 ITEM 1. Business

 Cincinnati Financial Corporation – Introduction
 We are an Ohio corporation formed in 1968. Our lead subsidiary, The Cincinnati Insurance Company, was founded in 1950. Our main business is property casualty insurance marketed through independent insurance agencies in 46 states. Our headquarters is in Fairfield, Ohio.

 Cincinnati Financial Corporation owns 100% of four subsidiaries: The Cincinnati Insurance Company (Cincinnati Insurance), Cincinnati Global Underwriting Ltd. SM (Cincinnati Global), CSU Producer Resources Inc. and CFC Investment Company. In addition, the parent company has an investment portfolio, owns the headquarters property and is responsible for corporate borrowings and shareholder dividends.

 The Cincinnati Insurance Company owns 100% of four additional insurance subsidiaries. Our standard market property casualty insurance group includes two of those subsidiaries – The Cincinnati Casualty Company and The Cincinnati Indemnity Company. This group writes a broad range of business, homeowner and auto policies. The Cincinnati Insurance Company also conducts the business of our reinsurance assumed operations, known as Cincinnati Re. Other subsidiaries of The Cincinnati Insurance Company include: The Cincinnati Life Insurance Company (Cincinnati Life), which provides life insurance policies and fixed annuities; and The Cincinnati Specialty Underwriters Insurance Company (Cincinnati Specialty Underwriters), which offers excess and surplus lines insurance products. In this report and elsewhere we often refer to any or all of these five companies as The Cincinnati Insurance Companies.

 Cincinnati Global owns 100% of Cincinnati Global Underwriting Agency Ltd. SM, a London-based, global specialty underwriter for Lloyd's Syndicate 318, and Cincinnati Global Dedicated No. 2 Ltd. SM, a Lloyd's corporate member and vehicle through which capital is provided by Cincinnati Financial Corporation and third-party names at Lloyd's.

 The two noninsurance subsidiaries of Cincinnati Financial Corporation are CSU Producer Resources, which offers insurance brokerage services to our independent agencies so their clients can access our excess and surplus lines insurance products; and CFC Investment Company, which offers commercial leasing and financing services to our agencies, their clients and other customers.

 Our filings with the U.S. Securities and Exchange Commission (SEC) are available on our website,
 investors.cinfin.com, as soon as possible after they have been filed with the SEC. Reports filed with the SEC may also be viewed at sec.gov. These filings include annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and exhibits and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934. In this report we reference various websites. These websites, including our own, are not incorporated by reference in this Annual Report on Form 10-K.

 Periodically, we refer to estimated industry data so that we can give information about our performance versus the overall U.S. insurance industry. Unless otherwise noted, the industry data is prepared by A.M. Best, a leading insurance industry statistical, analytical and insurer financial strength and credit rating organization. Information from A.M. Best is presented on a statutory accounting basis for insurance company regulation in the United States of America. When we provide our results on a comparable statutory accounting basis, we label it as such; all other company data is presented in accordance with accounting principles generally accepted in the United States of America (GAAP).

 Our Business and Our Strategy

 Introduction
 The Cincinnati Insurance Company was founded by four independent insurance agents and 2025 marks 75 years in business. They established the mission that continues to guide all of the companies in the Cincinnati Financial Corporation family – to grow profitably and enhance the ability of local independent insurance agents to deliver quality financial protection to the people and businesses they serve by:
 • providing insurance market stability through financial strength
 • producing competitive, up-to-date products and services
 • developing associates committed to superior service

 At year-end 2024, a select group of independent agencies in 46 states actively marketed our property casualty insurance within their communities. Standard market commercial lines and excess and surplus lines policies were
 marketed in 44 of those states. Personal lines policies were marketed in 45 of those states. Within our select group of agencies, we also seek to become the life insurance carrier of choice and to help agents and their clients – our policyholders – by offering leasing and financing services.

 Three competitive advantages distinguish our company, positioning us to build shareholder value and to be successful overall:
 • Commitment to our professional independent insurance agencies and to their continued success
 • Financial strength to fulfill our promises and be a consistent market for our agents' business, supporting stability and confidence
 • Operating structure that supports local decision making, showcasing our claims excellence and allowing us to balance growth with underwriting discipline

 Management and our board of directors has developed an agency-focused strategy that we believe positions our company for long-term success and value creation, while managing difficult economic, market or pricing cycles. We broadly group our key strategic initiatives into two areas of focus – managing insurance profitability and driving premium growth, as summarized below. Our strategic priorities include meeting the wants and needs of our agent customers, attracting and developing talented associates, achieving best-in-class field service and continually enhancing operational efficiency and effectiveness. To help guide our strategic efforts, we have placed an emphasis on innovation to accelerate operational improvement and to also favorably position us for the future. We find innovative ideas in many places, including: internally through management and other associates, with our traditional business partners and in the start-up business community.

 • Manage insurance profitability – Implementation of these initiatives is intended to enhance underwriting expertise and knowledge, thereby increasing our ability to manage our business while also gaining efficiency. We believe profit margins can be improved with additional information and expanded pricing capabilities we can access with the use of technology and analytics. This includes segmentation efforts that emphasize identification and retention of insurance policies we believe have relatively stronger pricing, while seeking more aggressive renewal terms and conditions on policies we believe have relatively weaker pricing. Pricing property casualty insurance policies includes estimates for expected losses, loss expenses to settle claims and expenses from underwriting policies while also considering the time value of money related to expected cash flows and a reasonable profit margin. In addition to enhancing company efficiency and more quickly deploying product or service enhancements, improving internal processes also supports the ability of the independent agencies that represent us to grow profitably by allowing them to serve clients faster and to more efficiently manage agency expenses as we make it easier for them to do business with us.
 • Drive premium growth – Implementation of these initiatives is intended to further penetrate each market we serve through our appointed independent agencies. Strategies aimed at specific market opportunities, along with service enhancements, can help our agents grow and increase our share of their business. This includes increasing opportunities for agencies to cross-serve their clients by providing updated products and services that aim to meet their life insurance needs. We continue to increase our capabilities to successfully underwrite both larger commercial policies, which we refer to as key accounts, and small business accounts that require greater efficiency. Premium growth initiatives also include expansion of Cincinnati Re and Cincinnati Global. Diversified growth also may reduce variability of losses from weather-related catastrophes.
 Cincinnati Financial Corporation - 2024 10-K - Page 6

 Independent Insurance Agency Marketplace
 The U.S. property casualty insurance industry is a highly competitive marketplace with more than 2,000 stock and mutual companies (carriers) operating independently or in groups.

 For the most part, we compete with standard market insurance companies that market through independent insurance agents. Agencies marketing our commercial lines or personal lines products typically represent several standard market insurance carriers. We also compete with carriers that market through captive agents representing a single carrier or that market directly to consumers, sometimes offering a less broad range of insurance products. Some of our agencies describe their roles as brokers instead of agents. Distribution through independent insurance agents or brokers represents approximately 60% of overall U.S. property casualty insurance premiums and approximately 80% of commercial property casualty insurance premiums, according to studies by the Independent Insurance Agents and Brokers of America.

 We are fully committed to the independent agency channel for marketing our insurance policies. For marketing standard lines insurance products, we choose independent agencies that share our philosophies. They generally do business person to person; offer broad, value-added services; and manage their agencies professionally, targeting long-term success. We develop our relationships with agencies, providing important knowledge of local market trends, opportunities and challenges.

 Our associates work to support agencies with tools and resources that help communicate the value of choosing an independent insurance agent and our insurance policies to their clients and prospective clients. We help our agencies meet the broader needs of their clients and increase and diversify their revenues and profitability by offering insurance solutions beyond our standard market property casualty insurance products. We market life insurance products through the agencies that offer our property casualty products and through other independent life agencies that represent Cincinnati Life without also representing our other subsidiaries. We operate our own excess and surplus lines insurance brokerage firm and insurance carrier so that we can offer our excess and surplus lines products exclusively to the independent agencies who market our other property casualty insurance products. Insurers operating in the excess and surplus lines marketplace generally market business through nonaffiliated excess and surplus lines brokers.

 The specialized nature of our other insurance operations helps avoid conflicts with the independent agency distribution channel. Cincinnati Re typically markets through broker organizations or similar intermediaries that specialize in reinsurance. Cincinnati Global markets its business through brokers and coverholders. Coverholders are entities that can be authorized by a Lloyd's syndicate to underwrite policies, manage risks, collect premiums or arrange claims settlements up to agreed upon limits.

 The table below includes data about property casualty agency relationships that market our standard market insurance products. It does not include Lloyd's brokers or coverholders that source business for Cincinnati Global.

 The annual total of agency new appointments may be partially offset by other changes in agency structures, such as consolidation through mergers or acquisitions. An increasing number of agencies have multiple, separately identifiable locations, reflecting their growth as well as consolidation of ownership within the independent
 Cincinnati Financial Corporation - 2024 10-K - Page 7

 agency marketplace. The number of reporting agency locations indicates our agents' regional scope and the extent of our presence within our active states. The difference between new appointments in total and the number of new relationships represents either: new branch offices opened by existing Cincinnati agencies; or agencies that merged with another Cincinnati agency and we still believed would produce a meaningful amount of new business premiums.

 On average, we have a 4.3% share of the standard lines property casualty insurance purchased through our reporting agency locations, according to 2023 data from agency surveys. Our share is 8.4% in reporting agency locations that have represented us for more than 10 years; 3.2% in agencies that have represented us for six to 10 years; 1.3% in agencies that have represented us for two to five years; and 0.3% in agencies that have represented us for one year or less.

 Our largest single agency relationship accounted for approximately 0.5% of our total property casualty earned premiums in 2024. No aggregate locations under a single ownership structure accounted for more than 8% of our earned premiums in 2024.

 Financial Strength
 We believe that our financial strength and strong capital and surplus position, reflected in our insurer financial strength ratings, are clear, competitive advantages in the segments of the insurance marketplace that we serve. This strength supports the consistent, predictable performance that our policyholders, agents, associates and shareholders have always expected and received, helping us withstand significant challenges.

 Effective capital management is an important part of creating long-term shareholder value, serving as a foundation to support other strategic areas focused on profitable growth of our insurance business. Our capital management philosophy is intended to preserve and build our capital while maintaining appropriate liquidity.

 While the potential exists for short-term financial performance variability due to our exposures to possible natural or man-made catastrophes or to significant capital market losses, the rating agencies consistently assert that we have built appropriate financial strength and flexibility to manage that variability. We remain committed to strategies that emphasize being a consistent, stable market for our agents' business rather than seeking short-term benefits that might accrue by quick, opportunistic reaction to changes in market conditions.

 We use various principles and practices such as diversification and enterprise risk management to maintain strong capital. For example, we maintain a diversified investment portfolio by reviewing and applying specific parameters and tolerances.
 • Our $16.182 billion fixed-maturity portfolio is diversified and exceeds total insurance reserves. The portfolio had an average rating of A2/A+, and its fair value exceeded total insurance reserve liabilities by approximately 25% at December 31, 2024. No corporate bond exposure accounted for more than 0.6% of our fixed-maturity portfolio, and no municipal exposure accounted for more than 0.1%.
 • The strength of our fixed-maturity portfolio provides an opportunity to invest for potential capital appreciation by purchasing equity securities. Our $11.185 billion equity portfolio minimizes concentrations in single stocks or industries. At December 31, 2024, no single security accounted for more than 8.3% of our portfolio of publicly traded common stocks, and no single sector accounted for more than 33%.

 Strong liquidity increases our flexibility through all periods to maintain our cash dividend and to continue to invest in and expand our insurance operations. At December 31, 2024, we held $5.243 billion of our cash and invested assets at the parent-company level, of which $4.563 billion, or 87.0%, was invested in common stocks, and $167 million, or 3.2%, was cash and cash equivalents.

 We minimize reliance on debt as a source of capital, with a debt-to-total-capital ratio of 5.5% at year-end 2024. Long-term debt at year-end 2024 totaled $790 million, matching year-end 2023, and our short-term debt was $25 million, matching the end of the prior year. The long-term debt consists of three nonconvertible, noncallable debentures, two due in 2028 and one in 2034. Ratings for our long-term debt are discussed in Item 7, Liquidity and Capital Resources, Long-Term Debt of Management's Discussion and Analysis.

 Cincinnati Financial Corporation - 2024 10-K - Page 8

 At year-end 2024 and 2023, risk-based capital (RBC) for our standard market property casualty insurance, excess and surplus lines insurance and life insurance subsidiaries was strong, far exceeding regulatory requirements.
 • We ended 2024 with a 1.0-to-1 ratio of property casualty premiums to surplus, a key measure of property casualty insurance company capacity and security. A lower ratio indicates more security for policyholders and greater capacity for growth by an insurer. We believe our ratio provides ample flexibility to diversify risk by expanding our operations into new geographies and product areas. The estimated industry average ratio was 0.8-to-1 at year-end 2024, based on industry data reported through the first nine months of 2024. On a statutory consolidated property casualty insurance basis, our ratio of investments in common stock, at fair value, to statutory capital and surplus was 72.3% at year-end 2024 compared with 83.2% at year-end 2023.
 • We ended 2024 with a 14.4% ratio of life statutory adjusted risk-based surplus to liabilities, a key measure of life insurance company capital strength. A higher ratio indicates an insurer's stronger security for policyholders and capacity to support business growth. Our life insurance subsidiary's RBC at year-end 2024 was 9.0 times the authorized control level RBC.

 Cincinnati Financial Corporation's senior debt is rated by four independent rating firms. In addition, the rating firms award our property casualty and life operations insurer financial strength ratings based on their quantitative and qualitative analyses. These ratings assess an insurer's ability to meet financial obligations to policyholders and do not necessarily address all of the matters that may be important to shareholders. Ratings may be subject to revision or withdrawal at any time by the ratings agency, and each rating should be evaluated independently of any other rating.

 At February 21, 2025, our insurance subsidiaries continued to be highly rated.

 Operating Structure
 We offer our broad array of insurance products through the independent agency distribution channel. We recognize that locally based independent agencies have relationships in their communities and local marketplace intelligence that can lead to profitable business and policyholder satisfaction and loyalty. Several of our strategic initiatives are intended not only to help us compete but also to enhance support of agencies that represent us, thereby contributing to agency success. We seek to be a consistent and predictable property casualty carrier that agencies can rely on to serve their clients.

 In our 10 highest volume states for consolidated property casualty premiums, 1,568 reporting agency locations wrote 50.1% of our 2024 consolidated property casualty earned premium volume compared with 1,487 locations and 50.1% in 2023. We continue efforts to geographically diversify our property casualty risks.

 Field Focus Emphasizing Service
 We rely on our force of 2,095 field associates to provide service and be accountable to our agencies for decisions we make at the local level. These associates live in the communities our agents serve, so they are readily available when agencies or policyholders need them. While their work is often conducted at the premises of the agency or policyholder, they also work from offices in their homes. Headquarters associates support agencies and field associates with underwriting, accounting, technology assistance, training and other services. Company executives and headquarters associates typically travel to visit agencies, strengthening the personal relationships we have with these organizations. Agents have opportunities for direct, personal conversations with our senior management team, and headquarters associates have opportunities to refresh their knowledge of marketplace conditions and field activities.

 The field team is coordinated by field marketing representatives responsible for underwriting new commercial lines business. They are joined by field representatives specializing in claims, loss control, commercial lines key accounts, personal lines, excess and surplus lines, machinery and equipment, management liability and surety, premium audit and life insurance. The field team provides a variety of services, such as recommending specific actions to improve the safety of the policyholder's operations. We seek to develop long-term relationships by understanding the unique needs of each agency's clients, who are also our policyholders.

 Technology enhances our service to agencies, allowing them to more easily access our systems and process business transactions. Policyholders can conveniently access pertinent policy information online, helping to reduce costs for agencies and the company. Technology and ongoing training also help our associates collaborate and process business efficiently, providing more time for personal service to agencies and their clients.

 We also provide and continue to develop enhanced, tailored services offered at the time a claim is reported for an insured loss event. Those services include assisting with car rental or towing, arranging temporary housing and coordinating emergency repairs to homes so additional damage is minimized.
 Cincinnati Financial Corporation - 2024 10-K - Page 10

 Our claims philosophy reflects our belief that we prosper as a company by responding to claims person to person, paying covered claims promptly, preventing false claims from unfairly adding to overall premiums and building financial strength to meet future obligations.

 Our 913 locally based field claims associates, often referred to as field claims representatives, work from their homes and are assigned to specific agencies. They respond personally to policyholders and claimants and are equipped to handle a claim from nearly anywhere. We believe we have a competitive advantage because of the person-to-person approach and the resulting high level of service that our field claims representatives and Express Claims Center associates deliver. For field claims representatives handling excess and surplus lines claims, guidance is provided by headquarters-based excess and surplus lines claims managers. Claims may be reported directly to us by calling our claims call center, online via our company website or through the MyCincinnatiSM app using a mobile device.

 Catastrophe response teams are comprised of our experienced field claims representatives who have the authority they need to do their jobs. In times of widespread loss, our field claims representatives confidently and quickly resolve claims, with the ability to provide claims payments on the same day they inspect the loss. Technology helps to enable fast initial contact with policyholders and easy sharing of information and data among storm teams, headquarters associates and local field claims representatives. When hurricanes or other weather events are predicted, we can identify through mapping technologies the expected number of our policyholders that may be impacted by the event and choose to have catastrophe response team members travel to strategic locations near the expected impact area. They are then in position to quickly get to the affected area and begin providing service to policyholders.

 Our 45 associates working in the Special Investigations Unit (SIU) include former law enforcement and claims professionals whose qualifications make them well suited to gathering facts to uncover potential fraud. While we believe our job is to pay what is due under each policy contract, we also want to prevent false claims from unfairly increasing overall premiums. Our SIU also contains a data analytics group and a computer forensics lab that supports field investigation efforts in various ways including assistance with link analysis, video evidence and data recovery.

 We seek to attract and retain high-quality independent insurance agencies with knowledgeable, professional staff. In turn, we make an exceptionally strong commitment to assist them in keeping their knowledge up to date and educating new people they bring on board as they grow. This includes offering classes, usually at no cost to agencies, except travel-related expenses they may incur, and other training support. We also offer noninsurance financial services. We believe that providing these services enhances agency relationships with the company and their clients, increasing loyalty while diversifying the agency's revenues.

 Cincinnati Financial Corporation - 2024 10-K - Page 11

 Human Capital
 At the end of 2024, we employed 5,624 associates, including 3,426 headquarters associates who provide support to 2,095 field associates and 103 associates at Cincinnati Global. The associate voluntary turnover rate was 4% in 2024, 6% in 2023 and 8% in 2022.

 We believe our compensation, training, technology, inclusive culture and career development opportunities help to attract and retain talented associates, which is critical to our strategy that emphasizes superior service to agencies and their clients, as described in this report. Our goal is to hire job candidates with promise, matching their strengths to positions within the company and providing resources to help them meet professional and personal goals. We are committed to providing equal opportunity for all associates, encouraging a work environment free from unlawful discrimination and harassment.

 We use multiple channels to ensure we attract a diverse pool of candidates rich with ideas and knowledge. For example, we build relationships with future talent by partnering with career services departments, faculty and staff at local and regional colleges and universities along with other programs that provide specific technical skills.

 We offer a base pay level for all roles that is competitive, market-based and re-evaluated on a recurring basis. The base pay is complemented by a matching 401(k) program, annual cash bonus and stock ownership opportunities along with healthcare benefits to provide a comprehensive compensation and benefits package. In addition, we have many special programs that appeal to associates while aligning with our corporate values. We believe our voluntary turnover rate indicates overall associate satisfaction with their working environment, compensation and benefits.

 We strive to offer equal pay for equal work and use independent consultants to conduct gender and ethnic minority pay equity studies examining total direct compensation, which consists of base salary, cash bonus and equity awards. Using a multivariate regression analysis, the independent studies in 2024 showed that we administer pay fairly and equitably because the factors used to make compensation decisions, such as role, salary grade, tenure and performance do in fact drive compensation awarded to each associate. More information is published in our Sustainability Report available on the Sustainability page of our website, investors.cinfin.com/sustainability, which is not incorporated by reference in this Annual Report on Form 10-K.

 We offer all regular, full- and part-time associates the opportunity to participate in the CFC Savings Plan, our 401(k) plan. We also offer all full-time associates the opportunity to purchase health, prescription, vision and dental insurance. Associates enrolled in our health plan can receive a free biometric screening – either onsite at our headquarters or with their personal physician. The screening helps associates learn about their health and identify risk factors while earning a company contribution into their Health Savings Account.

 While providing stock compensation at all levels of an organization may not be a common business practice, we firmly believe that stock ownership helps drive good decision making and encourages a long-term view by associates. We historically grant annual stock-based compensation to full-time, salaried associates in the form of stock options and restricted stock units that vest over time. In addition, each year all regular, full-time associates – salaried and hourly – are awarded one share of stock for each full calendar year of service, up to 10 shares, through our Holiday Stock Plan.

 Insurance Products
 We provide well-designed property casualty and life insurance products to bring policyholders convenience, discounts and a reduced risk of coverage gaps or disputes. For most agencies that represent us, we believe we offer insurance solutions for approximately 75% of the typical insurable risks of their clients. Products for various business lines within our reporting segments include insurance coverages for business property and liability, automobiles and homes.

 The table below shows net written premiums by segment and business line at year-end 2024, 2023 and 2022. We discuss our insurance segments in their respective sections later in this report.

 Our Segments
 Consolidated financial results primarily reflect the results of our five reporting segments. These segments are defined based on financial information we use to evaluate performance and to determine the allocation of assets.
 • Commercial lines insurance
 • Personal lines insurance
 • Excess and surplus lines insurance
 • Life insurance
 • Investments

 Revenues, income before income taxes and identifiable assets for each segment are shown in Item 8, Note 18 of the Consolidated Financial Statements. Some of that information is discussed in this section, where we explain the business operations of each segment. The financial performance of each segment is discussed in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations.

 Cincinnati Financial Corporation - 2024 10-K - Page 14

 Commercial Lines Insurance Segment
 In 2024, the commercial lines insurance segment contributed net earned premiums of $4.486 billion, representing 39.6% of consolidated total revenues. This segment reported profit before income taxes of $311 million. Commercial lines net earned premiums rose 5% in 2024 and 6% in 2023.

 We believe that our commercial lines business is best measured and evaluated on a segment basis. However, we also provide selected line of business data to summarize growth and profitability trends separately for our business lines. The five commercial business lines are:
 • Commercial casualty – Provides coverage to businesses against third-party liability from accidents occurring on their premises or arising out of their operations, including injuries sustained from products or liability related to professional services. Specialized casualty policies may include similar coverage such as umbrella liability or employment practices. The commercial casualty business line includes liability coverage written as part of commercial package policies.
 • Commercial property – Provides coverage for loss or damage to buildings, inventory and equipment caused by covered causes of loss such as fire, wind, hail, water, theft and vandalism, as well as business interruption resulting from a covered loss. Commercial property also includes other coverages such as inland marine, which covers losses related to builder's risk, cargo or equipment. Various property coverages can be written as stand-alone policies or can be added to a commercial package policy.
 • Commercial auto – Protects businesses against liability to others for both bodily injury and property damage, medical payments to insureds and occupants of their vehicles, physical damage to an insured's own vehicle from collision and various other perils, and damages caused by uninsured motorists.
 • Workers' compensation – Covers employers for government-specified benefits from work-related injuries to employees.
 • Other commercial lines – This includes several other types of insurance products for businesses, including:
 Management liability and surety – Includes director and officer (D&O) liability insurance, which covers liability for actual or alleged errors in judgment, breaches of duty or other wrongful acts related to activities of organizations and can optionally include other liability coverages. We market primarily to nonprofit organizations, privately held businesses, healthcare organizations, financial institutions and educational institutions. The for-profit portion includes approximately 120 bank or savings and loan financial institutions, with none having assets of $1 billion or more. The surety portion includes contract and commercial surety bonds for losses resulting from dishonesty, failure to perform and other acts and also includes fidelity bonds for fraudulent acts by specified individuals or dishonest acts by employees. Management liability coverage can also include cyber insurance as an affirmative coverage option on various insurance policies. We cede all of the related cyber insurance premiums to a reinsurer, therefore transferring substantially all of that risk. Ceded premiums for 2024 included $52 million for cyber insurance.
 Machinery and equipment – Specialized coverage provides protection for loss or damage to boilers and machinery, including production and computer equipment and business interruption, due to sudden and accidental mechanical breakdown, steam explosion or artificially generated electrical current.

 Our history of emphasizing products and services that agencies can market to small or midsized businesses in their communities remains a critical piece of our strategy even as we expand our appetite to insure larger businesses. While some of our property casualty agencies market only our personal lines or management liability and surety products, approximately 84% offer some or all of our standard market commercial insurance products.

 Cincinnati Financial Corporation - 2024 10-K - Page 15

 In 2024, our 10 highest volume commercial lines states generated 57.0% of our earned premiums compared with 56.2% in 2023. The aggregate number of reporting agency locations in our 10 highest volume states increased to 1,423 in 2024 from 1,330 in 2023.

 For new commercial lines business, policy-by-policy underwriting and pricing is coordinated by our locally based field marketing representatives who are also responsible for selecting new independent agencies. Our agents and our team of field associates get to know the people and businesses in their communities and can make informed decisions about each risk.

 Commercial lines policy renewals are managed by headquarters underwriters who are assigned to specific agencies and consult with local field associates as needed. As part of our team approach, headquarters underwriters also help oversee agency growth and profitability. They are responsible for formal issuance of all new business and renewal policies as well as policy endorsements. Further, the headquarters underwriters provide day-to-day customer service to agencies and our field marketing representatives by offering technical and industry expertise and product training, helping to determine underwriting eligibility and assisting with the mechanics of premium determination. We also continue a target markets emphasis to analyze opportunities and to develop new products and services, new coverage options and improvements to existing insurance products.

 Understanding evolving market conditions is a critical function for our success, accomplished through both informal commentary and formal reviews. Informally, our field marketing representatives, underwriters and product development associates routinely receive market intelligence from a variety of channels, including from the agencies with which they work. This market information helps identify the top competitors and our market strengths and weaknesses. The information obtained encompasses pricing, breadth of coverage and use of underwriting guidelines.

 Our historical emphasis on small to midsized businesses is reflected in the mix of our commercial lines premium volume by policy size. Approximately 70% of our commercial in-force policies have annual premiums of $10,000 or less, accounting in total for approximately 15% of our 2024 commercial lines premium volume. The remainder of policies have annual premiums greater than $10,000, including policies with annual premiums greater than $100,000 that account for approximately 35% of our 2024 commercial lines premium volume. Our average commercial lines policy size is approximately $17,000 in annual premiums.

 Our commercial lines packages typically are offered on a three-year policy term for most insurance coverages – a key competitive advantage. In our experience, multi-year packages appeal to the quality-conscious insurance buyers who we believe are typical clients of our independent agents. Customized insurance programs on a three-year term complement the long-term relationships these policyholders typically have with their agents and with our company. By reducing annual administrative efforts, multi-year policies lower expenses for our company and for our agents. The commitment we make to policyholders encourages long-term relationships and reduces their need to annually re-evaluate their insurance carrier or agency. We believe that the advantages of three-year policies in
 Cincinnati Financial Corporation - 2024 10-K - Page 16

 terms of improved policyholder convenience, increased account retention and reduced administrative costs outweigh the potential disadvantage of these policies, even in periods of rising rates.

 Although we offer three-year policy terms, premiums for some coverages within those policies are adjustable at the anniversary for the next annual period, and policies may be canceled at any time at the discretion of the policyholder. Contract terms often provide that rates for property, general liability, inland marine and crime coverages, as well as policy terms and conditions, are fixed for the term of the policy. However, the exposure we insure is reviewed annually, near the policy anniversary date, and the amount of premiums may be adjusted based on changes to that exposure.

 The general liability exposure basis may be audited annually. Commercial auto, workers' compensation, professional liability and most umbrella liability coverages within multi-year packages are rated at each of the policy's annual anniversaries for the next one-year period. The annual pricing could incorporate rate changes approved by state insurance regulatory authorities between the date the policy was written and its annual anniversary date, as well as changes in risk exposures and premium credits or debits relating to loss experience and other underwriting judgment factors. We estimate that approximately 75% of 2024 commercial premiums were subject to annual rating or were written on a one-year policy term. That 75% includes approximately one-third of policies offered on a three-year policy term that expire during any given year.

 We believe our commercial lines insurance segment premiums reflect a higher concentration, relative to industry commercial lines premiums, in contractor-related businesses. Since economic activity related to construction, which can heavily influence insured exposures of contractors, may experience cycles that vary significantly with the economy as a whole, our commercial lines premium trends could vary from commercial lines premium trends for the property casualty insurance industry. In 2024, we estimated that 38% of both our general liability premiums and our workers' compensation premiums came from the construction industry based on North American Industry Classification System (NAICS) codes.

 Personal Lines Insurance Segment
 The personal lines insurance segment contributed net earned premiums of $2.623 billion to 2024 consolidated total revenues, or 23.1% of the total, and reported profit before income taxes of $71 million. Personal lines net earned premiums rose 28% in 2024 and 21% in 2023.

 We prefer to write personal lines coverage in accounts that include both auto and homeowner coverages as well as coverages that are part of our other personal business line. At the end of 2024, for example, approximately 86% of our homeowner policies were accompanied by a personal auto policy in the same account. As a result of our account-based approach, we believe that our personal lines business is best measured and evaluated on a segment basis. However, we provide line of business data to summarize growth and profitability trends separately for three business lines:
 • Personal auto – Protects against liability to others for both bodily injury and property damage, medical payments to insureds and occupants of their vehicle, physical damage to an insured's own vehicle from collision and various other perils, and damages caused by uninsured motorists. In addition, many states require policies to provide first-party personal injury protection, frequently referred to as no-fault coverage.
 • Homeowner – Protects against losses to dwellings and contents from a wide variety of perils, as well as liability arising out of personal activities both on and off the covered premises. We also offer coverage for condominium unit owners and renters.
 • Other personal lines – This includes the other types of insurance products we offer to individuals, including dwelling fire, inland marine, personal umbrella liability and watercraft coverages.

 At year-end 2024, we marketed personal lines insurance products through 2,455, or approximately 73%, of our 3,355 agency reporting locations. The 2,455 personal lines agency locations were in 45 of the 46 states in which we offered property casualty insurance. Those agencies produced approximately 1.3 million personal lines policies in force for us, representing approximately 510,000 policyholders.

 Expansion of our personal lines insurance segment includes marketing through independent agencies to profitably grow our premiums for products and services offered to their high net worth personal lines clients. In 2024, our appointed agencies produced for us approximately $1.719 billion of net written premiums in total from policyholders with insured home values of $1 million or more, up 37% from 2023. We estimate those policyholders represent
 Cincinnati Financial Corporation - 2024 10-K - Page 17

 approximately 31% of our total personal lines policyholders. We refer to our high net worth products and services as Cincinnati Private ClientSM. Private client is a term used in the financial services industry to describe people who have complex needs based on their affluence, investments and belongings. It allows agencies and their customers to easily recognize that we stand ready to serve this client segment.

 In 2024, our 10 highest volume personal lines states generated 61.7% of our earned premiums compared with 63.5% in 2023. In 2015, our 10 highest volume personal lines states generated 78.5% of our earned premiums. The reduction in that percentage indicates progress over time toward our long-term objective of geographic diversification through new states for our personal lines operation. The aggregate number of reporting agency locations in our 10 highest volume states increased to 1,130 in 2024 from 1,055 in 2023.

 New and renewal personal lines business reflects our risk-specific underwriting philosophy. Each agency selects personal lines business primarily from within the geographic territory that it serves, based in part on agency staff's knowledge of the risks in those communities or familiarity with the policyholder. We have personal lines field marketing representatives who have underwriting authority and visit agencies on a regular basis. They focus primarily on key states targeted for growth, reinforcing the advantages of our personal lines products and offering training in the use of our policy processing system. Personal lines activities are further supported by headquarters associates assigned to individual agencies.

 Excess and Surplus Lines Insurance Segment
 The excess and surplus lines segment contributed net earned premiums of $615 million to 2024 consolidated total revenues, or 5.4% of the total, and reported profit before income taxes of $40 million. Excess and surplus lines net earned premium increased 13% in 2024 and 12% in 2023.

 Our excess and surplus lines policies typically cover business risks with unique characteristics, such as the nature of the business or its claim history, that are difficult to profitably insure in the standard commercial lines market. Excess and surplus lines insurers have more flexibility in coverage terms and rates compared with standard lines companies, generally resulting in policies with higher rates and terms and conditions customized for specific risks, including restricted coverage where appropriate. We target small to midsized risks, and policyholders in many cases also have standard market insurance with one of our other subsidiaries. Our average excess and surplus lines policy size is approximately $10,000 in annual premiums, and the majority have coverage limits of $1 million or less. All of our excess and surplus lines policies are written for a maximum term of one year. Approximately 89% of our 2024 earned premiums for the excess and surplus lines insurance segment provided commercial casualty coverages and about 11% provided commercial property coverages. Those coverages are described below.
 • Commercial casualty – Covers businesses for third-party liability from accidents occurring on their premises or arising out of their operations, including injuries sustained from products. Other coverages available include miscellaneous errors and omissions, professional liability and excess liability. Typical businesses covered include contractors, manufacturers, real estate owners and managers, retail, consultants, and bars or taverns. Policies covering liability at special events are also available.
 Cincinnati Financial Corporation - 2024 10-K - Page 18

 • Commercial property – Insures buildings, inventory, equipment and business income from loss or damage due to causes such as fire, wind, hail, water, theft and vandalism. Examples of property we commonly insure with excess and surplus lines policies include temporarily vacant buildings, habitational, restaurants and relatively higher-hazard manufacturing classes.

 At the end of 2024, we marketed excess and surplus lines insurance products in each of the 44 states in which we offer standard market commercial lines insurance. Offering excess and surplus lines helps agencies representing The Cincinnati Insurance Companies meet the insurance needs of their clients when coverage is unavailable in the standard market. By providing outstanding service, we can help agencies grow and prosper while also profitably growing our property casualty business.

 In 2024, our 10 highest volume excess and surplus lines states generated 53.9% of our earned premiums, compared with 53.5% in 2023.

 Agencies representing The Cincinnati Insurance Companies produce approximately $6 billion in annual premiums for all carriers writing excess and surplus lines policies for their clients. We estimate that approximately half of that premium volume matches the targeted business types and coverages we offer through our excess and surplus lines insurance segment. We structured the operations of this segment to meet the needs of these agencies and to market exclusively through them.

 Agencies have access to Cincinnati Specialty Underwriters' product line through CSU Producer Resources, the wholly owned insurance brokerage subsidiary of Cincinnati Financial Corporation. CSU Producer Resources has binding authority on all classes of business written through Cincinnati Specialty Underwriters and maintains appropriate agent and surplus lines licenses.

 We seek to earn a share of each agency's best excess and surplus lines accounts by offering several unique benefits. Agency producers have direct access through CSU Producer Resources to a group of our underwriters who focus exclusively on excess and surplus lines business. Those underwriters can tap into broader services we offer to provide policyholders additional value and help producers build the relationship through experienced and responsive loss control services and claims handling. CSU Producer Resources gives extra support to our independent agency producers by remitting surplus lines taxes and stamping fees and retaining admitted market diligent search affidavits, where required. Agencies marketing through CSU Producer Resources instead of a competing brokerage generally receive a higher commission because use of our internal brokerage subsidiary eliminates some of the intermediary costs. This business is factored in their profit-sharing agreement with The Cincinnati Insurance Companies. We also offer prompt service, generally issuing approximately 95% of policies within 24 hours of a request to bind a policy.

 Cincinnati Financial Corporation - 2024 10-K - Page 19

 Life Insurance Segment
 The life insurance segment contributed $321 million of net earned premiums, representing 2.8% of 2024 consolidated total revenues, and reported a gain before income taxes of $57 million. Life insurance net earned premiums increased 3% in 2024 and 4% in 2023.

 The Cincinnati Life Insurance Company supports our agency-centered business model by deepening the relationships we have with agents while also diversifying revenue and profitability for both the agency and our company. We primarily focus on life products that feature a steady stream of premium payments and that have the potential for generating revenue growth through increasing demand. Pricing life insurance policies includes assumptions for mortality, persistency, expenses and investment earnings while also considering the time value of money related to expected cash flows and a reasonable profit margin.

 Life Insurance Business Lines
 Four lines of business that account for approximately 99% of the life insurance segment's revenues are:
 • Term life insurance – Policies under which a death benefit is payable only if the insured dies during a specific period of time. Policy options include a return of premium provision, a benefit equal to the sum of all paid base premiums that is payable if the insured person survives to the end of the term. The policies are fully underwritten using traditional and accelerated methods.
 • Worksite products – Individually owned term life insurance, return of premium term life insurance and whole life insurance offered to employees on a voluntary basis through their employer. Premiums are collected by the employer using payroll deduction. Policies are issued using a simplified underwriting approach and on a guaranteed issue basis. Worksite insurance products provide our property casualty agency force with excellent cross-serving opportunities for both commercial and personal accounts.
 • Whole life insurance – Policies that provide life insurance for the entire lifetime of the insured. The death benefit is guaranteed never to decrease and premiums are guaranteed never to increase. While premiums are fixed, they must be paid as scheduled. These policies provide guaranteed cash values that are available as loans collateralized by the cash surrender value. The policies are fully underwritten.
 • Universal life insurance – Long-duration life insurance policies that are fully underwritten. Contract premiums are neither fixed nor guaranteed; however, the contract does specify a minimum interest crediting rate and a maximum cost of insurance charge and expense charge. The cash values, available as loans collateralized by the cash surrender value, are not guaranteed and depend on the amount and timing of actual premium payments and the amount of actual contract assessments.

 In addition, Cincinnati Life markets:
 • Deferred annuities that provide regular income payments that commence after the end of a specified period or when the annuitant attains a specified age. During the deferral period, any payments made under the contract accumulate at the crediting rate declared by the company but not less than a contract-specified guaranteed minimum interest rate. A deferred annuity may be surrendered during the deferral period for a cash value equal to the accumulated payments plus interest less the surrender charge, if any, and plus or minus a market value adjustment, if any.
 • Immediate annuities that provide some combination of regular income and lump-sum payments in exchange for a single premium.

 Life Insurance Distribution
 Cincinnati Life is licensed in 49 states and the District of Columbia. At year-end 2024, approximately 82% of our 2,175 property casualty agency relationships offered Cincinnati Life products to their clients. We also develop life business from approximately 466 other independent life insurance agencies. We are careful to solicit business from these other agencies in a manner that does not conflict with or compete with the marketing and sales efforts of our property casualty agencies.

 Cincinnati Financial Corporation - 2024 10-K - Page 20

 When marketing through our property casualty agencies, we have specific competitive advantages:
 • Because our property casualty operations are held in high regard, property casualty agency management is predisposed to consider selling our life products.
 • Marketing efforts for both our property casualty and life insurance businesses are directed by our field marketing department, coordinated with our life field marketing representatives, which assures consistency of communication and operations. Life field marketing representatives are available to meet face-to-face with agency personnel and their clients as well. Our life headquarters underwriters and other associates are available to the agents and field team to assist in the placement of business.

 We continue to emphasize the cross-serving opportunities of our life insurance, including term and worksite products, for the property casualty agency's personal and commercial accounts. In both the property casualty and independent life agency distribution systems, we enjoy the advantages of offering competitive, up-to-date products and providing personal attention in combination with financial strength and stability.
 • Term life insurance is our largest life insurance product line. We continue to develop and offer term products with features our agents indicate are important, such as a return of premium benefit and an accelerated underwriting option.
 • We also offer products addressing the needs of businesses with key person and buy-sell coverages. We offer quality, personal life insurance coverage to personal and commercial clients of our agencies.

 Because of our strong capital position, we can offer a competitive product portfolio, including guaranteed products, giving our agents a marketing edge. Our life insurance company maintains strong insurer financial strength ratings: A.M. Best, A+ (Superior); Fitch, A+ (Strong); and S&P, A+ (Strong). Our life insurance company has chosen not to establish a Moody's rating.

 Investments Segment
 Revenues of the investments segment are primarily from net investment income and from net investment gains and losses from investment portfolios managed for the holding company and each of the operating subsidiaries.

 Our investment department operates under risk guidelines set forth in our investment policy along with oversight of the investment committee of our board of directors. These guidelines set parameters for risk tolerances governing, among other items, the allocation of the portfolio as well as security and sector concentrations. These parameters are part of an integrated corporate risk management program. When allocating cash to various asset classes, we consider market-based factors such as risk adjusted after-tax yields as well as internal measures based in part on insurance department regulations and rating agency guidance.

 Cincinnati Financial Corporation - 2024 10-K - Page 21

 The fair value of our investment portfolio was $27.665 billion and $24.780 billion at year-end 2024 and 2023, respectively, as shown in the table below. The overall portfolio increased in fair value, including net purchases of securities in addition to an increase in its net investment gain position. The net investment gain position at year-end 2024, compared with year-end 2023, included a net increase for our equity security portfolio, reflecting a general increase in equity market valuations partially offset by equity securities sales. It also included a smaller net unrealized loss position in our fixed-maturity investments that reflected realized losses from the sales of some lower-yielding bonds in addition to tightening of corporate credit spreads.

 The cash we generate from insurance operations has been invested in three broad categories of investments:
 • Fixed-maturity investments – Includes taxable and tax-exempt bonds and redeemable preferred stocks. During 2024, the combined effect of purchases of securities and a net decrease in unrealized losses offset dispositions of fixed-maturity securities in our portfolio. During 2023, a net decrease in unrealized losses, combined with purchases, offset dispositions.
 • Equity investments – Includes common and nonredeemable preferred stocks. During 2024, the combined effect of a net increase in fair value and purchases of equity securities in our portfolio offset sales. During 2023, a net increase in fair value and purchases offset sales.
 • Short-term investments – Primarily commercial paper.

 In addition to securities held in our investment portfolio at year-end 2024, other invested assets included $567 million of private equity investments, $94 million of real estate through direct property ownership and development projects in the U.S., $36 million of life policy loans and $16 million held on deposit at Lloyd's.

 Our investment portfolio is further described below. Additional information about the composition and valuation of investments is included in Item 8, Note 2, Investments, and Note 3, Fair Value Measurements, of the Consolidated Financial Statements. A detailed listing of our portfolio is updated on our website, investors.cinfin.com, each quarter when we report our quarterly financial results.

 Fixed-Maturity Securities and Short-Term Investments
 By maintaining a well-diversified fixed-maturity portfolio, we attempt to manage overall interest rate, reinvestment, credit and liquidity risk. We pursue a buy-and-hold strategy and do not attempt to make large-scale changes to the portfolio in anticipation of rate movements. By investing new money on a regular basis and analyzing risk-adjusted after-tax yields, we work to achieve a general laddering effect to our portfolio that may mitigate some of the effects of adverse interest rate movements.

 At December 31, 2024, our investment-grade fixed-maturity securities represented 97.6% of the portfolio based on ratings provided by nationally recognized statistical ratings organizations or the Securities' Valuation Office of the National Association of Insurance Commissioners (NAIC). Nationally recognized statistical ratings organizations include Moody's, S&P, Fitch or Kroll Bond Rating Agency.

 While our strategy typically is to buy and hold fixed-maturity investments to maturity, we monitor credit profiles and fair value movements when determining holding periods for individual securities. With the exception of U.S. agency issues, no individual issuer's securities accounted for more than 0.8% of the taxable fixed-maturity portfolio at year-end 2024. Investment-grade corporate bonds had an average rating of Baa1 by Moody's or BBB+ by S&P at year-end 2024. Our taxable fixed-maturity portfolio included $551 million of asset-backed securities with an average rating of Aa1/AA at year-end 2024.

 Relative to a broad bond market index such as the Barclay's Aggregate, we are most heavily exposed to the investment-grade corporate bond asset class. Within that asset class, we have a weighting of 33.8% for the financial sector, lower than the 36.5% weighting for the financial sectors of the Bank of America Merrill Lynch U.S. Corporate Index.

 At December 31, 2024, we had $3.939 billion of tax-exempt fixed-maturity securities with an average rating of Aa2/AA by Moody's and S&P. The portfolio is well diversified among approximately 1,900 municipal bond issuers. No single municipal issuer accounted for more than 0.6% of the tax-exempt fixed-maturity portfolio at year-end 2024.

 Our short-term investments consist of commercial paper purchased within one year of maturity. We make short-term investments primarily with funds to be used to make upcoming cash payments, such as dividends, taxes or other corporate purposes. At year-end 2024, we had $298 million of short-term investments compared with none at year-end 2023.

 Equity Securities Investments
 After covering both our intermediate and long-range insurance obligations with fixed-maturity investments, we historically have used some available cash flow to invest in equity securities. Our equity securities portfolio includes common stocks and nonredeemable preferred stocks, primarily in larger-capitalization companies but sometimes in smaller entities with attractive growth prospects. Investments in equity securities have played an important role in achieving our portfolio objectives and have contributed to both growth of investment income and portfolio appreciation. We remain committed to our long-term equity focus, which we believe is a key factor to our company's long-term growth and stability. We believe our strategy of primarily investing in a diversified selection of high-quality, larger-capitalization, dividend-increasing companies generally results in reduced volatility relative to the broader equity markets.

 For federal income tax purposes, taxes on gains from appreciated investments generally are not due until securities are sold. We believe that the appreciated value of equity securities, compared with the cost of securities that is generally used as a tax basis, is a useful measure to help evaluate how fair value can change over time. On this basis, the net unrealized investment gains at year-end 2024 consisted of a net gain position in our equity portfolio of $7.232 billion. Events or factors such as economic growth or recession can affect the fair value of our equity securities.

 At year-end 2024, Apple Inc. (Nasdaq: AAPL) was our largest single common stock investment, comprising 8.2% of our publicly traded common stock portfolio and 3.2% of the entire investment portfolio. The five largest holdings in our common stock portfolio were Apple, Microsoft (Nasdaq: MSFT), Broadcom Inc. (Nasdaq: AVGO), JPMorgan Chase & Co (NYSE:JPM) and Abbvie Inc. (NYSE:ABBV), which had a combined fair value of $2.992 billion or 27.6% of our publicly traded common stock portfolio. The parent company held 42.1% of our common stock holdings (measured by fair value). The distribution of the portfolio among industry sectors is shown in the table below.

 We evaluate nonredeemable preferred stocks in a manner similar to our evaluation of fixed-maturity investments, seeking attractive relative yields. We generally focus on investment-grade nonredeemable preferred stocks issued by companies with strong histories of paying common dividends, providing us with another layer of protection. Consideration is also given to nonredeemable preferred stocks that offer a dividend received deduction for income tax purposes. We did not purchase any nonredeemable preferred stocks during 2024. During 2023, we purchased $22 million of nonredeemable preferred stocks.

 Other
 What we report as Other includes the noninvestment operations of the parent company and its noninsurer subsidiary, CFC Investment Company. At year-end 2024, this subsidiary had $120 million in receivables related to its commercial leasing and financing services, compared with $108 million in receivables at year-end 2023.

 We also report as Other the results of Cincinnati Re, which has contracts, also referred to as treaties, with other insurance or reinsurance companies to assume a portion of their insured risk in exchange for a portion of premiums from insurance policies covering those risks. The treaties and their exposure to losses are diverse in nature, including various lines of business and geographies for the reinsured risks. Some of our treaties reflect a type of contract commonly referred to as participating or proportional, typically sharing premiums and losses between the reinsured entity and us, as reinsurer, on a pro rata basis. Some are a contract type commonly referred to as excess of loss, where we indemnify the reinsured entity only for losses exceeding a predetermined amount.

 Net written premiums for Cincinnati Re totaled $597 million in 2024, compared with $558 million in 2023. Approximately 39% of 2024 net written premiums was for property exposures that include risk of loss from natural catastrophes and approximately 44% was for casualty exposures from various liability risks. The remainder of approximately 17% was a combination of what we consider to be more specialized coverages that include, but are not limited to, credit risk transfer related to residential mortgages, marine and energy risks and cyber risks.

 Also reported as Other are the results of Cincinnati Global, our London-based global specialty underwriter for Lloyd's Syndicate 318, which we acquired on February 28, 2019. We expect it to continue contributing to future earnings and book value growth. We provide capability for appointed independent agencies to offer their clients insurance solutions in the Lloyd's market through our insurance brokerage, CSU Producer Resources. Cincinnati Global and CSU Producer Resources partner by offering a variety of products through a binder authority agreement, enhancing our ability to serve more of our agent's clients and bring quality business to Cincinnati Global.

 Net written premiums for Cincinnati Global totaled $303 million in 2024, compared with $280 million in 2023. We continued to diversify its premiums to reduce underwriting profit volatility effects of property insurance. Most of the 2024 premiums were for U.S. and international property exposures that include risk of loss from natural catastrophes, including approximately 44% classified as direct and facultative and 20% as binder, where binding authority has been granted to various coverholders. The coverholders are mostly in the U.S., and we believe they have the ability to successfully underwrite and manage risks. The remainder, approximately 36%, was for other classes of business that include trade credit, terrorism, political violence, specie coverage for high-value portable property and contingency insurance with coverage for film and entertainment risks or event cancellation.

 Regulation
 The business of insurance in the United States (U.S.) is primarily regulated by state law. All of our U.S. insurance company subsidiaries are domiciled in the state of Ohio except The Cincinnati Specialty Underwriters Insurance Company, which is domiciled in the state of Delaware. Each domestic insurance subsidiary is primarily governed by the insurance laws and regulations in its respective state of domicile. We also are subject to regulatory authorities of all states in which we write insurance. The state laws and regulations that have the most significant effect on our insurance operations and financial reporting are discussed below.
 • Insurance Holding Company Regulation – We are regulated as an insurance holding company system in the respective states of domicile of our lead standard market property casualty company subsidiary and its surplus lines insurance subsidiary. These regulations require that we annually furnish financial and other information about the governance and operations of the individual companies within the holding company system. Information about the risks posed by any noninsurance company subsidiaries must also be disclosed. All transactions within a holding company system affecting insurers must be fair and equitable. Notice to the state insurance commissioner is required prior to the consummation of transactions affecting the ownership or control of an insurer and prior to certain material transactions between an insurer and any person or entity in its holding company group. In addition, some of those transactions cannot be consummated without the commissioner's prior approval.
 • Subsidiary Dividends – The Cincinnati Insurance Company is fully owned by Cincinnati Financial Corporation and is our lead insurance subsidiary. The dividend-paying capacity of The Cincinnati Insurance Company and its fully owned subsidiaries is regulated by the laws of the applicable state of domicile. Under these laws, our domestic insurance subsidiaries must provide a 10-day advance informational notice to the insurance commissioner for the domiciliary state prior to payment of any dividend or distribution to its shareholders. Generally, the most our domestic insurance subsidiaries can pay without prior regulatory approval is the greater of 10% of statutory capital and surplus or 100% of statutory net income for the prior calendar year.
 The domestic insurance company subsidiaries must give 30 days of notice to, and obtain prior approval from, the state insurance commissioner before the payment of an extraordinary dividend as defined by the state's insurance code. You can find information about the dividends paid by our lead insurance subsidiary during 2024 in Item 8, Note 9 of the Consolidated Financial Statements.
 • Insurance Operations – All of our domestic insurance subsidiaries are subject to licensing and supervision by departments of insurance in the states in which they do business. The nature and extent of such regulations vary, but generally are rooted in statutes that delegate regulatory, supervisory and administrative powers to state insurance departments. Such regulations, supervision and administration of the domestic insurance subsidiaries include: the standards of solvency that must be met and maintained; the licensing of insurers and their agents and brokers; the nature and limitations on investments; deposits of securities for the benefit of policyholders; regulation of standard market policy forms and premium rates; policy cancellations and nonrenewals; test audit programs; periodic examination of the affairs of insurance companies; annual and other reports required to be filed on the financial condition of insurers or for other purposes; requirements regarding reserves for unearned premiums, losses and other matters; the nature of and limitations on dividends to policyholders and shareholders; the nature and extent of required participation in insurance guaranty funds; the involuntary assumption of hard-to-place or high-risk insurance business, primarily workers' compensation insurance; and the collection, remittance and reporting of certain taxes and fees. Our primary insurance regulators in the U.S. have adopted the Model Audit Rule for annual statutory financial reporting. This regulation closely mirrors the Sarbanes-Oxley Act on matters such as auditor independence, corporate governance and internal controls over financial reporting. The regulation permits the audit committee of Cincinnati Financial Corporation's board of directors to also serve as the audit committee of each of our insurance subsidiaries for purposes of this regulation.
 • Insurance Guaranty Associations – For certain obligations of insolvent insurance companies to policyholders and claimants, states assess each member insurer in an amount relative to the insurer's proportionate share of business written by all member insurers in the state. While the amount of such assessments has not been material in recent years, we cannot predict the amount and timing of any future assessments or refunds on our insurance subsidiaries under these laws.
 Cincinnati Financial Corporation - 2024 10-K - Page 26

 • Shared Market and Joint Underwriting Plans – Assigned risk plans, reinsurance facilities and joint underwriting associations are mechanisms that generally provide applicants with various basic insurance coverages when they are not available in voluntary markets. States can require participation based upon the amount of an insurance company's voluntary market share, and underwriting results related to these pools could be adverse to our company.
 • Statutory Accounting – For public reporting, domestic insurance companies prepare financial statements in accordance with GAAP. However, certain data also must be calculated according to statutory accounting rules as defined in the NAIC's Accounting Practices and Procedures Manual. While not a substitute for any GAAP measure of performance, statutory data frequently is used by industry analysts and other recognized reporting sources to facilitate comparisons of the performance of insurance companies.
 • Insurance Reserves – State insurance laws require that property casualty and life insurers annually analyze the adequacy of reserves. Our appointed actuaries must submit an opinion that reserves are adequate for policy claims-paying obligations and related expenses.
 • Investment Regulation – Insurance company investments must comply with laws and regulations pertaining to the type, quality and concentration of investments. Such laws and regulations permit investments in federal, state and municipal obligations, corporate bonds, preferred and common equity securities, mortgage loans, real estate and certain other investments, subject to specified limits and other qualifications.
 • Risk-Based Capital Requirements – The NAIC's risk-based capital (RBC) requirements for property casualty and life insurers serve as an early warning tool for the NAIC and state regulators to identify companies that may be undercapitalized and may merit further regulatory action. The NAIC has a standard formula for annually assessing RBC. The formula for calculating RBC for property casualty companies takes into account asset and credit risks but places more emphasis on underwriting factors for reserving and pricing. The formula for calculating RBC for life insurance companies takes into account factors relating to insurance, business, asset and interest-rate risks.
 Although the federal government and its regulatory agencies generally do not directly regulate the business of insurance, federal legislation and administrative rules adopted can affect our business. Privacy laws, such as the Gramm-Leach-Bliley Act, the Fair Credit Reporting Act and the Health Insurance Portability and Accounting Act (HIPAA) are the federal laws that most affect our day-to-day operations. These apply to us because we gather and use personal nonpublic information to underwrite insurance and process claims. We also are subject to other federal laws, such as the Terrorism Risk Insurance Act (TRIA), anti-money laundering statute (AML), the Nonadmitted and Reinsurance Reform Act (NRRA), the U.S. Foreign Corrupt Practices Act (FCPA), and the rules and regulations of the Office of Foreign Assets Control (OFAC).

 Title V of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank) created the Federal Insurance Office to monitor the insurance industry and gather information to identify issues or gaps in the regulation of insurers that could contribute to a systemic crisis in the insurance industry that affects the United States' financial system and to recommend to the Financial Stability Oversight Council that it designate an insurer as a systemically significant entity requiring additional supervision by the Federal Reserve Board. We do not expect Dodd-Frank to result in federal oversight of our operations as a systemically significant entity.

 We do not expect to have any material effects on our expenditures, earnings or competitive position as a result of compliance with any federal, state or local provisions enacted or adopted relating to the protection of the environment. We currently do not have any material estimated capital expenditures for environmental control facilities.
 Cincinnati Financial Corporation - 2024 10-K - Page 27

 We operate in limited foreign jurisdictions. Our foreign insurance subsidiary, Cincinnati Global Underwriting Ltd., based in the United Kingdom (U.K.), holds a group of companies led by our managing agency, Cincinnati Global Underwriting Agency Ltd., of Lloyd's Syndicate 318, which is regulated by The Prudential Regulation Authority (PRA) and The Financial Conduct Authority (FCA). The PRA's primary objective with respect to insurers is to promote the safety and soundness of insurers for the protection of policyholders, while the FCA has three operational objectives: (i) to secure an appropriate degree of protection for consumers; (ii) to protect and enhance the integrity of the U.K. financial system; and (iii) to promote effective competition in the interests of consumers in the financial services markets. The PRA/FCA's Senior Managers and Certification Regime provides regulatory frameworks for standards of fitness and propriety, conduct and accountability for individuals in positions of responsibility at insurers. The PRA and FCA have also delegated certain additional regulatory responsibilities to the Council of Lloyd's. By virtue of Lloyd's international licenses, we can write business in various countries throughout the world. In each such country, we are subject to the laws and insurance regulations of that jurisdiction.

 Our operations in the U.K. are further subject to regulations retained following the U.K.'s exit from the European Union (EU). Generally, these requirements were adopted by the EU and then implemented by enabling legislation in the member countries. Significant areas of oversight in the U.K. include capital, solvency and risk management requirements (Solvency II), competition law and antitrust regulation, intermediary and distribution regulation, climate change, gender discrimination and data protection and privacy (General Data Protection Regulation).

 Cincinnati Financial Corporation - 2024 10-K - Page 28

 Enterprise Risk Management
 We manage enterprise risk, including cybersecurity risk, through formal risk management programs overseen by an executive officer of the company. Our ERM framework includes an enterprise risk management committee, which is responsible for overseeing risk activities and is comprised of senior executive-level risk owners from across the enterprise. The risk committee's activities are supported by a team of representatives from business areas that focus on identifying, evaluating and developing risk plans for emerging risks, including cybersecurity risks. A comprehensive report is provided quarterly to our chairman and chief executive officer and also to our board of directors and our senior executive team, as appropriate, on the status of risk metrics relative to identified tolerances and limits, risk assessments and risk plans. The use of operational audits, strategic plans and departmental business plans, as well as our culture of open communications and fundamental respect for our Code of Conduct, continue to help us manage risks on an ongoing basis. Our efforts to assess, identify and manage material risks from cybersecurity threats is further discussed in Item 1C, Cybersecurity.

 Our risk management programs include a formalized risk appetite element and a risk identification and quantification process. The overall enterprise objective is to appropriately balance risk and reward to achieve an appropriate return on risk capital. Our key risks are discussed in Item 1A, Risk Factors, including risks related to natural catastrophes, investments and operations.

 We continue to study emerging risks, including climate change risk and its potential financial effects on our results of operations and on those we insure. These effects include deterioration in the credit quality of our municipal or corporate bond portfolios and increased losses without sufficient corresponding increases in premiums. As with any risk, we seek to identify the extent of the risk exposure and possible actions to mitigate potential negative effects of risk at an enterprise level.

 Cincinnati Financial Corporation - 2024 10-K - Page 29

 ITEM 1A. Risk Factors
 Our business involves various risks and uncertainties that may affect achievement of our business objectives. Many of the risks could have ramifications across our organization. For example, risks related to setting insurance rates and establishing and adjusting loss reserves could have an impact on our investment activities, growth and overall results if actual results differ from our assumptions, judgments or estimates in these areas.

 The following discussion should be viewed as a starting point for understanding the significant risks we face. We organized the risks within each section to express the level of impact each could have on the company's value. This ordering contemplates both the magnitude and probability of a particular risk. It is not a definitive summary of their potential impacts or of our strategies to manage and control the risks. See Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, for a discussion of those strategies.

 If any risks or uncertainties discussed here have or will develop into actual events, they could have a material adverse effect on our business, financial condition, results of operations or cash flows. The failure of our risk management strategies could also have a material adverse impact. In that case, the market price of our common stock could decline materially.

 Readers should carefully consider this information together with the other information we have provided in this report, other reports and materials we file periodically with the Securities and Exchange Commission, news releases and other information we disseminate publicly.

 Risks related to insurance operations

 Loss reserves, our largest liability, are based on estimates and could be inadequate to cover actual losses.
 Our consolidated financial statements are prepared using GAAP. These principles require us to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes. Actual results could differ materially from those estimates. For a discussion of the significant accounting policies we use to prepare our financial statements, the material implications of uncertainties associated with the methods, assumptions and estimates underlying our critical accounting policies and the process used to determine our loss reserves, refer to Item 8, Note 1 of the Consolidated Financial Statements, and Item 7, Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves and Life Insurance Policy Reserves.

 Our most critical accounting estimate is loss reserves. Loss reserves are estimates and are inherently uncertain; they do not and cannot represent an exact measure of liability. Inflationary scenarios, especially scenarios outside of historical norms, or regulatory changes that affect the assumptions underlying our critical accounting estimates, may make it more difficult to estimate loss reserves. Examples of inflation effects include adverse changes in the tort environment caused by more aggressive attorney involvement in insurance claims, increased litigation, expanded theories of liability, higher jury awards, lawsuit abuse and third-party litigation funding. Accordingly, our loss reserves for past periods could prove to be inadequate to cover our actual losses and related expenses. Any changes in these estimates are reflected in our results of operations during the period in which the changes are made. An increase in our loss reserves would decrease earnings, while a decrease in our loss reserves would increase earnings.

 Unforeseen losses, or unintended coverages, the type and magnitude of which we cannot predict, may emerge. These additional losses could arise from changes in the legal environment, new or amended laws and regulations, climate change, catastrophic events, increases in loss severity or frequency, environmental claims, mass torts or other causes such as social inflation. Such future losses could be substantial. The increase in inflation in recent periods has significantly increased our loss costs in our auto and property businesses. It is possible that inflation could remain at high levels for a prolonged period or increase further, leading to additional increases in our loss costs. In addition, a significant portion of claims costs consists of medical costs. As a result, an increase in medical inflation could materially and adversely impact our loss costs and our loss reserves. Recent changes in the macroeconomic environment have impacted medical labor and materials costs, the potential persistency of which could result in future loss costs that are higher than our current expectations.

 Our life policy reserves are also subject to uncertainty. Periods of higher death claims outside of long-term historical norms, such as during the COVID-19 pandemic, and not anticipated within our actuarial models could make our life policy reserves inadequate to cover actual future death claims. Increases in estimates of future death claims would increase life policy reserve levels and in turn decrease earnings.
 Cincinnati Financial Corporation - 2024 10-K - Page 30

 In addition to the risks stated above, Cincinnati Re reserves are subject to uncertainty because a reinsurer relies on the original underwriting decisions and claims reserving practices of ceding companies. As a result, we are subject to the risk that ceding companies may not have adequately evaluated the risks reinsured by us and the premiums ceded may not adequately compensate us for the risks we assume. In addition, there is generally a longer lapse of time from the occurrence of the event to the reporting of the loss or benefit to the reinsurer and ultimate resolution or settlement of the loss. Similar risks exist for Cincinnati Global due to potential delays in loss reporting.

 Because of the inherent uncertainties involved in setting reserves, we cannot provide assurance that our existing reserves or future reserves will prove adequate in light of subsequent events. Our results of operations and financial condition have in the past been, and in the future could be, materially affected by adverse loss development for events that we insured in prior periods.

 We could experience an unusually high level of losses due to natural or man-made catastrophe, terrorism or epidemic events or risk concentrations.
 Our insurance operations expose us to claims arising out of catastrophes, which can be man-made or caused by natural perils in the U.S. or worldwide. Man-made catastrophes include, but are not limited to, industrial accidents, terrorist attacks, wars, cyberattacks, infrastructure failures, social unrest and riot. Other man-made events, such as hydraulic fracturing could cause damage from earth movement, while chemicals and other contaminants could create environmental and/or health hazards that in turn generate insurance losses. The geographic regions in which we market insurance and reinsurance are exposed to numerous natural catastrophes, such as:
 • Hurricanes
 • Earthquakes in many regions, most particularly in the New Madrid fault zone, California, the Northwest and Southwest
 • Landslides
 • Severe convective storms, tornadoes, windstorms, hailstorms and flooding
 • Wildfires
 • Winter storms

 On a worldwide basis, in the event of a severe catastrophic event or terrorist attack we may be exposed to material losses through our Cincinnati Re and Cincinnati Global operations. Due to the nature of these events, we are unable to precisely predict the frequency, severity or potential cost of catastrophe occurrences.

 The extent of losses from a catastrophe is a function of both the total amount of insured and reinsured exposure in the area affected by the event and the severity of the event. Our ability to appropriately manage catastrophe risk depends partially on catastrophe models, which may be affected by inaccurate or incomplete data, the uncertainty of the frequency and severity of future events and the uncertain impact of climate change. Additionally, these models are recalibrated and changed over time, with more data availability and changing opinions regarding the effect of current or emerging loss patterns and conditions. See Item 7, Liquidity and Capital Resources, Modeled Catastrophe Loss Exposure, for a further discussion of the loss estimates derived from these models.

 According to these models, probable maximum loss estimates from a single hurricane event that combines the effects of property casualty insurance written on a direct basis by The Cincinnati Insurance Companies, the Cincinnati Re reinsurance portfolio and risks insured by Cincinnati Global include the following amounts, net of amounts recoverable through reinsurance ceded and income taxes, and including the effects of estimated reinstatement premiums: $625 million for a once-in-a-100-year event and $949 million for a once-in-a-250-year event. See Item 7, Liquidity and Capital Resources, Modeled Catastrophe Loss Exposure, for a discussion of modeled losses considered in evaluating our risk mitigation strategy, which includes our ceded reinsurance program.

 The occurrence of terrorist attacks in the geographic areas we serve could result in substantially higher claims under our insurance policies than we have anticipated. Some of our insurance policies provide coverage for terrorism risk in all areas we serve, including Tier 1 and Tier 2 cities. We have exposure to small co-op utilities, water utilities, wholesale fuel distributors, small shopping malls and small colleges throughout our 46 active states. Because of the number of associates located at our Fairfield, Ohio, headquarters, it is also exposed to terrorism risk. Additionally, our life insurance subsidiary could be adversely affected in the event of a terrorist event or an
 Cincinnati Financial Corporation - 2024 10-K - Page 31

 epidemic, particularly if the epidemic were to affect a broad range of the population or affect the overall economy. A catastrophe or epidemic event also could affect our operations by damaging our headquarters facility, injuring associates and visitors or disrupting our associates' ability to perform their assigned tasks. Our associate health plan is self-funded and could similarly be affected.

 Our results of operations would be adversely affected if the level of losses we experience over a period of time were to exceed our actuarially determined expectations. In addition, our financial condition may be adversely affected if we were required to sell securities prior to maturity or at unfavorable prices to pay an unusually high level of loss and loss expenses. Securities pricing might be even less favorable as a result of widespread losses and catastrophic events impacting a number of other companies and insurers. We also may be exposed to state guaranty fund assessments if other carriers in a state cannot meet their obligations to policyholders.

 We market our standard market property casualty insurance products in 46 states, but our business is concentrated in the Midwest and Southeast, with a growing presence in California and New York. Our geographic concentration links our performance to business, economic, environmental and regulatory conditions in some states more than others. We also have exposure in states where we do not actively market insurance when clients of our independent agencies have businesses or properties in multiple states or we provide insurance through Cincinnati Global and reinsurance through Cincinnati Re.

 Cincinnati Re and Cincinnati Global provide reinsurance or insurance coverage for property catastrophe events on a worldwide basis, including coverage for losses due to war, terrorism or political violence. Wars can occur anywhere, and our results of operations could be adversely affected, especially if effects of wars expand over time and space. We have limited direct exposure within our insurance operations to businesses or individuals in Russia, Ukraine or Gaza. We have exposure within our insurance operations, primarily through reinsurance treaties, to insured losses related to wars that include risks in the Middle East region. If effects related to the war in Gaza expand significantly in the Middle East region, causing a high frequency of loss events, or a single extreme event, during the coverage period of our treaties or policies, our financial position and results of operations could be materially affected. Cincinnati Re is staffed with seasoned underwriting and analytical associates who strive to assume risks that we understand, both quantitatively and qualitatively, but given their global scope, a failure of their risk selection and modeling could materially affect our financial position and results of operations. We are also expanding Cincinnati Global, our global specialty underwriter with premiums primarily for U.S. and international property exposures. Cincinnati Global also writes North American and United Kingdom (U.K.) contingency and event cancellation coverage and worldwide credit and political risk coverage and political violence coverage. If there is a high frequency of large property catastrophe or terrorism events, or a single extreme event, during the coverage period of Cincinnati Global's policies, our financial position and results of operations could be materially affected.

 Climate change may adversely impact our results of operations and/or our financial position.
 Scientists have linked global climate change from rising planet temperatures over the last several decades to a number of factors that contribute to the increased unpredictability, frequency, duration and severity of weather events. This includes changing weather patterns, a rise in ocean temperatures and sea level. Certain catastrophe models assume an increase in frequency and severity of certain weather or other events, which could result in a disproportionate impact on insurers with certain geographic concentrations of risk. Changes in climate and/or weather patterns may increase the frequency and/or intensity of severe weather and natural catastrophe events, including hurricanes, heavy precipitation events, heavy wind events, flash flooding, sea level rise, droughts, heat waves and wildfires potentially leading to increased insured losses. A continuation of these trends would also likely increase the risks of writing property insurance in coastal areas or areas susceptible to wildfires or flooding, or in areas susceptible to heavy wind events. The risk could be even greater in jurisdictions that restrict pricing and underwriting flexibility. We cannot predict how legal, regulatory or social responses to concerns about climate change may impact our business.

 Our pricing and capital models could be flawed.
 We use various actuarial pricing methods, predictive pricing and underwriting models, stochastic models and/or forecasting techniques to help us understand our business, analyze risk and estimate future trends. The output of these techniques and models assists us in making underwriting, pricing, reinsurance, reserving and capital decisions and helps us set our strategic direction. These models contain numerous assumptions, including the assumption that the data used is sufficient and accurate. They are also subject to uncertainties and limitations inherent in any statistical analysis. Actual results may be materially different from modeled output, resulting in pricing our products incorrectly, overestimating or underestimating reserves, or inaccurately forecasting the impact of modeled events on our results. This could materially adversely impact the results of our operations.
 Cincinnati Financial Corporation - 2024 10-K - Page 32

 Our ability to properly underwrite and price risks and increased competition could adversely affect our results.
 Our financial condition, results of operations and cash flows depend on our ability to underwrite and set rates accurately for a full spectrum of risks. We establish our pricing based on assumptions about the level of losses that may occur within classes of business, geographic regions and other criteria.

 To properly price our products, we must collect, properly analyze and use data to make decisions and take appropriate action; the data must be sufficient, reliable and accessible. We also need to develop appropriate rating methodologies and formulae; and we need to identify and respond to trends quickly. We may overestimate or underestimate loss cost trends or these trends may unexpectedly change – such as inflation in recent years outside of historical norms – leading to losing business by pricing risks above our competitors or charging rates too low to maintain profitability. Legal trends in recent years have also made it more difficult to determine adequate pricing, including adverse changes in the tort environment caused by more aggressive attorney involvement in insurance claims, increased litigation, expanded theories of liability, higher jury awards, lawsuit abuse and third-party litigation funding. If rates are not accurate, we may not generate enough premiums to offset losses and expenses, or we may not be competitive in the marketplace. Cincinnati Global has additional risks due to its reliance on coverholders in underwriting parts of its business.

 Our ability to set appropriate rates are hampered if states where we write business refuse to allow rate increases that we believe are necessary to cover the risks insured. A state could also hamper our ability to set appropriate rates if it no longer allows us to use factors that we believe are predictive of loss, such as credit-based factors. Limitations on our ability to use various types of artificial intelligence (AI) in the development of pricing precision could adversely affect underwriting results. Multiple states require us to purchase reinsurance from a mandatory reinsurance fund. Such reinsurance funds can create a credit risk for insurers if not adequately funded by the state and, in some cases, the existence of a reinsurance fund could affect the prices charged for our policies. The effect of these and similar arrangements could reduce our profitability in any given period or limit our ability to grow our business.

 The insurance industry is cyclical and competitive. From time to time, the industry goes through prolonged periods of intense competition during which it is more difficult to attract new business, retain existing business and maintain profitability. Competition in our insurance business is based on many factors, including:
 • Competitiveness of premiums charged
 • Relationships among carriers, agents, brokers and policyholders
 • Underwriting and pricing methodologies
 • Compensation provided to agents
 • Underwriting discipline
 • Terms and conditions of insurance coverage
 • Speed with which products are brought to market
 • Product and marketing innovations, including advertising
 • Technological competence and innovation
 • Ability to control expenses
 • Quality of services and tools provided to agents and policyholders
 • Claims satisfaction and reputation

 We compete with major U.S., Bermudian, European, and other international insurers and reinsurers and with underwriting syndicates, some of which have greater financial, marketing and management resources than we do. Industry consolidation, including business combinations among insurance and other financial services companies, has resulted in larger competitors with even greater financial resources. We also compete with new companies that continue to enter the insurance and reinsurance markets. In addition, capital market participants have created alternative products that are intended to compete with Cincinnati Re's reinsurance products. Increased competition could result in fewer submissions, lower premium rates, and less favorable policy terms and conditions, which could reduce our underwriting margins and have a material adverse effect on our results of operations and financial condition.
 Cincinnati Financial Corporation - 2024 10-K - Page 33

 If our pricing were incorrect or we were unable to compete effectively because of one or more of these factors, our premium writings could decline and our results of operations and financial condition could be materially adversely affected. Large competitors could intentionally disrupt the market by targeting certain lines or underpricing the market. See the discussion of our Commercial Lines, Personal Lines, Excess and Surplus Lines and Life Insurance Segments in Item 1, Our Segments, for a discussion of our competitive position in the insurance marketplace.

 We rely primarily on independent insurance agents to distribute our products.
 We market our main products, insurance policies for businesses and individuals, through independent, nonexclusive insurance agents. These agents sell our competitors' products and are not obligated to promote our products. We must offer insurance products that meet the needs of these agents and their clients. We need to maintain good relationships with the agents who market our products. If we do not, these agents may market our competitors' products instead of ours. This could lead to a less desirable mix of business and affect our results of operations.

 Certain events or conditions could diminish our agents' desire to produce business for us and the competitive advantage that our independent agents enjoy, including:
 • Downgrade of the financial strength ratings of our insurance subsidiaries.
 • Concerns that doing business with us is difficult or not profitable, perceptions that our level of service is no longer a distinguishing characteristic in the marketplace, perceptions that our products do not meet the needs of our agents' clients or perceptions that our business practices are not compatible with agents' business models.
 • Mergers and acquisitions of agencies could result in a concentration of a significant amount of premium in one agency or a small number of agencies.
 • Delays in the development, implementation, performance and benefits of technology systems and enhancements or independent agent perceptions that our technology solutions do not match their needs.

 Certain changes to our independent agency appointment strategy could affect our results of operations, including:
 • A reduction in the number of independent agencies marketing our products.
 • The failure of agencies to successfully market our products or pay amounts due to us,
 • Changes in the strategy or operations of agencies or the choice of agencies to reduce their writings of our products.
 • Inability to replace underperforming or nonperforming agencies with agencies that produce adequate and profitable premiums.
 • A decline in the quality of independent agencies we are appointing.

 Our ability to react to changes in consumer behavior and preferences.
 The appeal of our value proposition could be affected by an unexpected change in the commoditization of insurance products. Policyholders may choose a competitor's product rather than our own because of real or perceived differences in price, terms and conditions, coverage or service. If the quality of the independent agencies with which we do business were to decline, that also might cause policyholders to purchase their insurance through different agencies or channels. Consumers, especially in the personal insurance industry segment, may increasingly choose to purchase insurance from distribution channels other than independent insurance agents. Increased advertising by insurers, especially direct marketers, could cause consumers to shift their buying habits, bypassing independent agents altogether. Innovation, new or changing technologies and/or buying trends or consumer preferences could reduce or eliminate the need or demand for products we sell.

 Economic downturns or other events have in the past and may in the future result in a softening of the insurance market and agents or consumers choosing a competitor's product that may in turn adversely affect our premium revenues and underwriting profit. Such economic events experienced during recent periods included elevated inflation, global supply chain disruptions, increasing interest rates, tightening credit markets and higher fuel costs.

 Cincinnati Financial Corporation - 2024 10-K - Page 34

 Our ability to obtain or collect on our reinsurance protection could affect our business, financial condition, results of operations or cash flows.
 We buy property casualty and life reinsurance coverage to mitigate the liquidity risk and earnings volatility risk of an unexpected rise in claims severity or frequency from catastrophic events or a single large loss. The availability, amount and cost of reinsurance depend on market conditions and may vary significantly. If we were unable to obtain reinsurance on acceptable terms and in appropriate amounts, our business and financial condition could be adversely affected. Our reinsurers might experience significant losses, potentially jeopardizing their ability to pay losses we cede to them. It could also reduce the availability of reinsurance. If we cannot obtain adequate reinsurance or primary insurance coverage at a reasonable cost, it could constrain how much business we can write.

 In addition, we are subject to credit risk with respect to our reinsurers. Although we purchase reinsurance to manage our risks and exposures to losses, this reinsurance does not discharge our direct obligations under the policies we write. We would remain liable to our policyholders even if we were unable to recover what we believe we are entitled to receive under our reinsurance contracts. Reinsurers might refuse or fail to pay losses that we cede to them, or they might delay payment. For long-tail claims, the creditworthiness of our reinsurers may change before we can recover amounts to which we are entitled. A reinsurer's insolvency, inability or unwillingness to make payments under the terms of its reinsurance agreement with our insurance subsidiaries could have a material adverse effect on our financial position, results of operations or cash flows. See Item 7, Liquidity and Capital Resources, 2025 Reinsurance Ceded Programs, for a discussion of selected reinsurance transactions.

 Our credit ratings or financial strength ratings of our insurance subsidiaries could be downgraded.
 We believe our strong insurer financial strength ratings, in particular, the A+ (Superior) ratings from A.M. Best for our standard market property casualty insurance group and each subsidiary in that group, are an important competitive advantage. If our property casualty or life insurance subsidiary insurer financial strength ratings were to be downgraded, our agents might find it more difficult to market our products or might choose to emphasize the products of other carriers. Additionally, a downgrade in our ratings may adversely impact our Cincinnati Re operations by reducing our ability to market our reinsurance products or compete with other highly rated reinsurers. A downgrade in one or more of our company's credit or debt ratings could adversely impact our borrowing costs or access to capital. Our ratings are subject to periodic review and there is no assurance that our ratings will not be changed. Rating agencies could change or expand their requirements or could find that our insurance subsidiaries no longer meet the criteria established for current ratings. See Item 1, Our Business and Our Strategy, Financial Strength, for additional discussion of our financial strength ratings.

 International operations subject us to additional regulation and expose us to additional investment, political and economic risks.
 International risks include restrictions such as price controls, capital controls, currency exchange limits, ownership limits and other restrictive or anti-competitive governmental actions or requirements, which could have an adverse effect on our business and reputation. Our business activities outside the U.S., including in the U.K., subject us to political and economic risks, including foreign currency and credit risk. Cincinnati Global in particular is subject to continued political and economic disruptions in the U.K. from its withdrawal from the European Union.

 Business activities outside the U.S. subject us to additional domestic and foreign laws and regulations, including the Foreign Corrupt Practices Act, the U.K. Bribery Act and similar laws in other countries that prohibit the making of improper payments to foreign officials. In addition, insurers in the U.K. (including managing agents and members of Lloyd's of London) are subject to Solvency II and the U.K. regulatory regime, which itself includes rules promulgated by Lloyd's. Although we have policies and controls in place that are designed to ensure compliance with these laws and regulatory requirements, if those controls are ineffective and an employee or intermediary fails to comply with applicable laws and regulations, we could suffer civil and criminal penalties and our business and reputation could be adversely affected. Some countries have laws and regulations that lack clarity and, even with local expertise and effective controls, it can be difficult to determine the exact requirements of, and potential liability under, the local laws. Failure to comply with local laws in a particular market may result in substantial liability and could have a significant and negative effect not only on our business in that market but also on our reputation generally.

 Business activities at Cincinnati Global are subject to Lloyd's approval of a business plan each year. There is risk that Cincinnati Global's plan will not be approved or will be limited. As a Lloyd's managing agent and syndicate, Cincinnati Global is exposed to various risks and their associated uncertainties, including Lloyd's rating agency
 Cincinnati Financial Corporation - 2024 10-K - Page 35

 ratings and reputation. Cincinnati Global also has an obligation to maintain funds at Lloyd's to support its underwriting activities and periodic assessment of its capital, governance and other aspects of its business.

 Risks related to investments or other financial matters

 Financial disruption or a prolonged economic downturn could affect our investment performance.
 Events, such as global supply chain disruptions, an increasing interest rate environment and inflationary pressures, have contributed to significant disruption and volatility for financial markets and decreased economic activity. In the event that these conditions occur or continue, recur or result in a prolonged economic downturn or recession, they could materially and adversely impact our financial condition, results of operations or cash flows. These market conditions have in the past, and could in the future, cause our investment income or the value of securities we own to decrease. Additionally, the companies we invest in might be severely affected by a severe catastrophic event, terrorist attack, or epidemic event, which could in turn lower their stock value and affect our financial condition and results of operations.

 Our ability to achieve our performance objectives could be affected by changes in the financial, credit and capital markets or the general economy.
 We invest premiums received from policyholders and other available cash to generate investment income and capital appreciation, while also maintaining sufficient liquidity to pay covered claims and operating expenses, service our debt obligations and pay dividends. The value of our invested assets is an important component of shareholders' equity or book value per share and changes in their valuation can have a significant impact. Changes in book value per share is a key performance objective as discussed in Item 7, Executive Summary of Management's Discussion and Analysis.

 For fixed-maturity investments such as bonds, which represented 58.4% of the fair value of our investment portfolio at the end of 2024, the inverse relationship between interest rates and bond prices leads to falling bond values during periods of increasing interest rates. Significant increases in the general level of interest rates, such as we experienced during recent periods, have an adverse effect on our shareholders' equity.

 Investment income is an important component of our revenues and net income. The ability to increase investment income and generate longer-term growth in book value is affected by factors beyond our control, such as: inflation, economic growth, interest rates, world political conditions, changes in laws and regulations, future actions or inactions of the U.S. government, epidemic events, terrorism attacks or threats, war, adverse events affecting other companies in our industry or the industries in which we invest, market events leading to credit constriction, and other widespread unpredictable events. These events have in the past and may in the future adversely affect the economy generally and cause our investment income or the value of securities we own to decrease. Wars can occur anywhere in the world and have an adverse effect on our investment portfolio, especially if effects of wars expand over time and space. We do not have material exposure to investments based in Russia, Ukraine, Israel or Gaza. If there is significant expansion of wars beyond these regions, it may have adverse effects on our investment performance. Any significant decline in our investment income will have an adverse effect on our net income, and thereby on our shareholders' equity and our statutory capital and surplus. For a more detailed discussion of risks associated with our investments, refer to Item 7A, Quantitative and Qualitative Disclosures About Market Risk.

 We have issued universal life contracts with guaranteed minimum returns, referred to as bank-owned life insurance contracts (BOLIs). A BOLI is designed with the bank as the policy owner and the policy beneficiary. We legally segregate and record as separate accounts the assets and liabilities for certain BOLIs, when required by the specific contract provisions. Minimum investment returns, account values and death benefits are guaranteed by us for our separate account BOLIs. We could incur losses in the performance of these guarantees.

 We also have life policy reserves established for traditional life policies including term, whole life and other products. Reserve variability can occur as reserves are based on certain cash flow assumptions as well as a discount rate assumption. Life policy reserves are required to be recorded using a discount rate assumption that is updated quarterly. As the discount rate increases during the quarter, life policy reserves decrease and accumulated other comprehensive income (AOCI) increases. Conversely, as the discount rate decreases during the quarter, life policy reserves increase and AOCI decreases. A significant decrease in discount rates, relative to the prior quarter, would have an adverse effect on shareholders' equity.

 Cincinnati Financial Corporation - 2024 10-K - Page 36

 Our investment performance also could suffer because of the types of investments, industry groups and/or individual securities in which we choose to invest. Market value changes related to these choices could cause a material change in our financial condition or results of operations.

 Our investments in private equity, private credit, real property assets, private limited partnerships, and other alternative investments are subject to a higher level of illiquidity, economic volatility and real estate market deterioration. They lack quoted prices and active trade markets, and are subject to changing tax laws and an increased focus from the SEC and other regulators. These alternative investments have in the past, and may in the future result in reduced net investment returns, losses on sales of these investments, and/or the writing down the value of these investments, which would result in an adverse impact on operating results.

 We also are exposed to credit risk related to guarantee and indemnification arrangements, which support our alternative investments and insurance operations. Our exposure to these guarantee and indemnification risks could materially and adversely affect our results of operations.

 At year-end 2024, common stock holdings made up 39.2% of our investment portfolio. Adverse news or events affecting the global or U.S. economy or the equity markets, such as we experienced during recent years, will affect our net income, book value and overall results, and could affect our ability to pay our common stock dividend. See Item 7, Investments Results, and Item 7A, Quantitative and Qualitative Disclosures About Market Risk, for a discussion of our investment activities.

 Deterioration in the banking sector or in banks with which we have relationships could affect our results of operations. Our ability to maintain or obtain short-term lines of credit could be affected if the banks from which we obtain these lines are acquired, fail or are otherwise negatively affected. We may lose premium revenue if a bank that owns appointed agencies were to change its strategies. We could experience increased losses in our director and officer liability line of business if claims were made against insured financial institutions.

 A deterioration of credit and market conditions could also impair our ability to access credit markets and could affect existing or future lending arrangements. In addition, a failure to comply with covenants and other requirements under our credit facilities, senior debt and other debt obligations could have a material adverse effect on us and our ability to access the credit markets.

 Our overall results are affected if a significant portion of our commercial lines or personal lines policyholders are adversely affected by marked or prolonged economic downturns and events such as a downturn in construction and related sectors, tightening credit markets and higher fuel costs experienced during recent periods. Such events make it more difficult for policyholders to finance new projects, complete projects or expand their businesses, and can lead to lower premiums from reduced payrolls and sales and lower purchases of equipment and vehicles. These events could also cause claims, including surety claims, to increase due to a policyholder's inability to secure necessary financing to complete projects or to collect on underlying lines of credit in the claims process. Such economic downturns and events have a greater impact in the construction sector where we have a concentration of risks and in geographic areas that are hardest hit by economic downturns.

 Deteriorating economic conditions could also increase the degree of credit risk associated with amounts due from independent agents who collect premiums for payment to us and could hamper our ability to recover amounts due from reinsurers.

 Our status as an insurance holding company with no direct operations could affect our ability to pay dividends in the future.
 Cincinnati Financial Corporation is a regulated holding company that transacts substantially all of its business through its subsidiaries. Our primary assets are the stock in our operating subsidiaries and our investments. Consequently, our cash flow to pay cash dividends and interest on our long-term debt depends on dividends we receive from our operating subsidiaries and income earned on investments held at the parent-company level.

 Dividends received from our lead insurance subsidiary are restricted by the insurance laws of Ohio, its domiciliary state. These laws establish minimum solvency and liquidity thresholds and limits. Generally, the maximum dividend that may be paid is limited to the greater of 10% of statutory capital and surplus or 100% of statutory net income for the prior calendar year. Dividends exceeding these limitations may be paid only with prior approval of the Ohio Department of Insurance. Meanwhile, other subsidiaries are also limited in their payment of dividends to the lead
 Cincinnati Financial Corporation - 2024 10-K - Page 37

 insurance subsidiary under applicable insurance laws. We might not be able to receive dividends in the amounts necessary to meet our debt obligations or to pay dividends on our common stock without liquidating securities. See Item 1, Regulation, and Item 8, Note 9 of the Consolidated Financial Statements, for a discussion of insurance holding company dividend regulations.

 General risk factors

 The effects of changes in industry practices, laws and regulations on our business are uncertain.
 As industry practices and legal, judicial, legislative, regulatory, political, social and other environmental conditions change, unexpected and unintended issues related to insurance pricing, claims and coverage emerge. There has been increased regulatory scrutiny of the use of machine learning and AI, and it is likely that we will be subject to new regulations that could materially adversely affect our operations or ability to write business profitably in one or more jurisdictions. These issues, and others, may adversely affect our business by impeding our ability to obtain adequate rates for covered risks or otherwise extending coverage beyond our underwriting intent, by increasing the number or size of claims, by varying assumptions underlying our critical accounting estimates or by increasing duties owed to policyholders beyond contractual obligations. In some instances, unforeseeable emerging and latent claim and coverage issues and court decisions or legislative changes may not become apparent until sometime after we have issued the insurance policies that could be affected by the changes. As a result, the full extent of liability under our insurance contracts may not be known for many years after a policy is issued and our pricing and reserve estimates may not accurately reflect its effect.

 Some of our existing or potential shareholders, policyholders, associates, regulators, and other stakeholders will evaluate our business practices according to a variety of sustainability guidelines and expectations, including those related to climate change, inclusive diversity and equity, data privacy, and the well-being of our employees. Our business practices and disclosures are evaluated against sustainability guidelines, which are continually evolving and not always well defined or readily measurable today. Our practices may not change in the particular ways or at the rate stakeholders expect, leading to business or reputational challenges.

 We are required to adopt new or revised accounting standards issued by recognized authoritative organizations, including the Financial Accounting Standards Board (FASB) and the SEC. Future changes required to be adopted could change the current accounting treatment that we apply and could result in material adverse effects on our results of operations, financial position or cash flows.

 Our investment income benefits from tax rate preferences for municipal bond interest and dividend income from equity securities. Market valuations for these securities also benefit from the tax-preference aspect of current tax laws, affecting the value of our investment portfolio and also shareholders' equity. Future changes in tax laws, or other changes such as regulations for applicability of alternative minimum taxes, could result in material adverse effects on our results of operations and financial condition.

 The NAIC, state insurance regulators and state legislators continually re-examine existing laws and regulations governing insurance companies and insurance holding companies, specifically focusing on modifications to statutory accounting principles, interpretations of existing laws, regulations relating to product forms and pricing methodologies and the development of new laws and regulations that affect a variety of financial and nonfinancial components of our business. Any proposed or future legislation, regulation or NAIC initiatives, if adopted, may be more restrictive on our ability to conduct business than current regulatory requirements or may result in higher costs. The loss or significant restriction on the use of a particular variable, such as credit, in pricing and underwriting our products could lead to future unprofitability and increased costs.

 Federal laws and regulations and the influence of international laws and regulations, including those that may be enacted in the wake of the financial and credit crises, may have adverse effects on our business, potentially including a change from a state-based system of regulation to a system of federal regulation, the repeal of the McCarran Ferguson Act, and/or measures under the Dodd-Frank Act that established the Federal Insurance Office and Financial Stability Oversight Council. The expansion of federal measures that change the scope of insurance and financial regulation may restrict our ability to conduct our insurance business, govern our corporate affairs or increase our cost of doing business.

 In addition, climate change and climate change transitions may continue to lead to new or enhanced regulation, which may be difficult or costly to comply with, or impact assets that we invest in, which may result in realized and
 Cincinnati Financial Corporation - 2024 10-K - Page 38

 unrealized losses in future periods that could have a material adverse impact on our results of operations and/or financial position. It is not possible to foresee the impacts of potential future climate regulation, or which, if any, assets, industries or markets may be materially and adversely affected by global climate change and global climate change transitions, nor is it possible to foresee the magnitude of such effects. The effects of such changes could adversely affect our results of operations. See Item 7, Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves and Life Insurance Policy Reserves, for a discussion of our reserving practices.

 Elevated inflation negatively impacts profit and the value of investments.
 Inflation in various forms, such as we experienced in recent periods, reduces underwriting profitability due to higher losses and loss expenses to repair damaged autos or other property that we insure. Inflationary volatility has and may in the future have an increased impact on us due to the three-year rates offered on some of our commercial lines policies. Elevated inflation can also be in the form of social inflation of litigation costs, jury awards and settlement expectations. In addition to adverse effects on the fair value of our equity portfolio, inflationary pressures can also cause or contribute to, or are the result of, increases in interest rates, which reduces the fair value of our fixed-maturity portfolio.

 Managing technology initiatives and meeting data security requirements are significant challenges.
 We use technology to process, store, retrieve, evaluate and use customer and company data and information. Our information technology and telecommunications systems, in turn, interface with and rely upon third-party systems. We must be able to access our systems to provide insurance quotes, process premium payments, make changes to existing policies, file and pay claims, provide customer support, manage our investment portfolios, report on financial results and perform other necessary business functions. Systems failures or outages could compromise our ability to perform these business functions in a timely manner, which could harm our ability to conduct business and hurt our relationships with our business partners and customers. In the event of a disaster such as a natural catastrophe, a pandemic, civil unrest, an industrial accident, a cyberattack, a blackout, a terrorist attack (including conventional, nuclear, biological, chemical or radiological) or war, systems upon which we rely may be inaccessible to our associates or independent agents for an extended period of time. Even if our associates and independent agents are able to report to work, they may be unable to perform their duties for an extended period of time if our data or systems used to conduct our business are disabled or destroyed. While technology can streamline many business processes and reduce the costs of operations, technology initiatives present short-term cost and also have implementation and operational risks. In addition, we may have inaccurate expense projections, implementation schedules or expectations regarding the effectiveness and user acceptance of the end product. These issues could escalate over time. If we were unable to find and retain associates with key technical knowledge, our ability to develop and deploy key technology solutions could be hampered.

 Our systems have been, and will likely continue to be, subject to viruses or other malicious code, unauthorized access, cyberattacks, cyber frauds or other computer-related penetrations. Increasing sophistication of cyber criminals and terrorists make keeping up with new threats difficult and could result in a breach. Patching and other measures to protect existing systems and servers could be inadequate, especially on systems that are being retired. Controls employed by our U.S., off-shore and cloud vendors could prove inadequate. We could also experience a breach by intentional or negligent conduct on the part of associates or other internal or external sources. Independent agencies with access to our systems and servers expose us to additional cyber threats. Our systems and those of third-party vendors may become vulnerable to damage or disruption due to circumstances beyond our or their control, such as from catastrophic events, power anomalies or outages, natural disasters, network failures, viruses, ransomware and malware.

 A breach of our security or the security of a vendor that results in unauthorized access to our data could expose us to a disruption or challenges relating to our daily operations as well as to data loss, litigation, damages, fines and penalties, significant increases in compliance costs and reputational damage. From time to time we have had to, and in the future we may need to, increase or expend resources to investigate or remediate vulnerabilities as a result of data security incidents. Such resources are costly in time and expense, and detract from resources spent on or are otherwise devoted to our core operations. In addition, depending on the nature of an incident, we may not be able to detect an incident readily, assess its severity or impact, or appropriately respond in a timely manner, which could increase our risk and exposures. See Item 1C, Cybersecurity, for further discussion of our cybersecurity risk management, strategy and governance.

 Cincinnati Financial Corporation - 2024 10-K - Page 39

 Any failure to protect the confidentiality of customer information could adversely affect our reputation or expose us to fines, penalties or litigation, which could impact our business, financial condition and results of operations.
 We necessarily collect, use and hold data concerning individuals and businesses with whom we have a relationship. We are required to safeguard the confidential personal information of our customers and applicants. We are subject to an increasing number of federal, state, local and international laws and regulations regarding privacy and data security, as well as contractual commitments. These laws and regulations are rapidly evolving, complex, vary significantly among jurisdictions, and sometimes conflict. In the absence of updated, uniform federal privacy legislation, there is a growing trend in the states in which we operate, to adopt comprehensive privacy legislation that provides consumers with various privacy rights and imposes significant compliance burdens on covered companies. Failure to comply with data security or privacy laws or regulations could subject us to regulatory enforcement actions and fines, penalties, litigation, private rights of action or public statements against us by consumer advocacy groups or others if confidential customer information is misappropriated from our computer systems, those of our vendors, our independent agents or others with whom we do business, or otherwise. Despite the security measures that may be in place, any such systems may be vulnerable to the types of attacks and security incidents described above. Any well-publicized compromise of security could deter people from entering into transactions that involve transmitting confidential information, impart reputational or other harm, and/or have a material adverse effect on our business. Additionally, privacy legislation may make our business partners more reluctant to share information with us that is useful in conducting our business.

 Our business depends on the uninterrupted operation of our facilities, systems, people and business functions.
 Our business depends on our associates' ability to perform necessary business functions, such as processing new and renewal policies and handling claims. We increasingly rely on technology and systems to accomplish these business functions in an efficient and uninterrupted fashion. Our inability to access our headquarters facilities for certain critical functions or a failure of technology, telecommunications or other systems or the loss or failure of services provided by key vendors, could significantly impair our ability to perform such functions on a timely basis or affect the accuracy of transactions. If sustained or repeated, such a business interruption or system failure could result in a deterioration of our ability to write and process new and renewal business, serve our agents and policyholders, pay claims in a timely manner, collect receivables or perform other necessary business functions. If our disaster recovery and business continuity plans did not sufficiently consider, address or reverse the circumstances of an interruption or failure, this could result in a materially adverse effect on our operating results and financial condition.

 Our ability to successfully execute business functions also depends on hiring and retaining the qualified associates we employ. Competition for high-quality executives and other key associates occurs within the insurance industry and from other industries. We also must effectively develop and manage associates, including providing training and resources. Such tools and information can allow them to effectively perform critical business functions and adapt to changing business needs. During tight labor markets, such as we experienced in recent years, there is intense competition for associates qualified to execute important business functions. Many markets in which we operate are experiencing a low unemployment rate and labor shortages are affecting many industries. If we are unable to attract and retain certain associates, or if we fail to provide adequate training or resources, or fail to provide a work environment that is attractive to associates, we could limit the success of executing our strategic plans and vital business functions.

 Loss of key personnel or an inability to successfully execute on succession plans could negatively impact growth, essential business relationships, profitability, and other business operations. Specifically, in May 2024, we underwent a CEO transition as part of a long-term succession plan. An inability to successfully execute on the leadership transition could result in an adverse effect on our operating results and financial condition.

 ITEM 1C. Cybersecurity

 Risk Management and Strategy
 As discussed further in Item 1, Regulation, Enterprise Risk Management, we manage cybersecurity as part of our overall enterprise risk programs.

 As part of this program to keep our systems and data secure and to assist in understanding, assessing, identifying and managing material risks from cybersecurity threats, we take various measures through internal risk management efforts and testing by third-party experts. Those measures assess our cybersecurity program structure and capabilities and include blocking attempted cyber intrusions, defending against service disruptions, performing frequent vulnerability assessments and maintaining procedures to ensure timely notification of critical cybersecurity incidents and performance of related disclosure controls. We also have developed procedures and reporting processes when we identify an attempted cyber intrusion to the systems of one of our independent agents.

 Additionally, the company uses third-party service providers, or vendors, in the course of conducting its operations. As such, the company has measures in place to help identify material risks from cybersecurity threats associated with the use of those vendors. When work with a vendor is evaluated, we consider, among other items, the availability of system and organization control reports, the use of artificial intelligence, interactions with our systems, the data involved and its level of sensitivity, the amount of data the vendor will process, where the data will be stored, what they will do with the data and destruction of data. Once a vendor is approved by the appropriate personnel, expectations regarding incident reporting are established and followed.

 We are not aware of having experienced a material cybersecurity incident and we take commercially reasonable measures, described above and below, to monitor and respond to threats to keep our systems and data secure. However, we acknowledge that administrative, technical and internal accounting controls as well as other preventative actions may be insufficient to prevent security breaches to our systems or those of third parties with whom we do business due to, among other factors, changing technologies as well as criminal and state-sponsored cybercrime and cyber threats. Further, a material breach of our security or the security of a vendor that results in unauthorized access to our data could expose us to a disruption or challenges relating to our daily operations as well as to data loss, litigation, damages, fines and penalties, significant increases in compliance costs and reputational damage and could affect the company's strategy, results of operations or financial condition. See Item 1A, Risk Factors, for additional details.

 Governance
 Cybersecurity matters are an important part of reporting to our board of directors, executive management team, risk committee and disclosure committee. From a board perspective, the audit committee oversees the company's cybersecurity efforts along with additional oversight from the entire board. Two members of the audit committee have obtained certifications in cybersecurity oversight. Each quarter, the chief information officer and chief information security officer report to the audit committee on cybersecurity risks and controls. Also occurring each quarter, the entire board, and our senior executive team, as appropriate, receives a comprehensive report from the chief risk officer on the status and management of risk and other metrics relative to identified tolerances and limits, risk assessments and risk plans. Additionally, the chief risk officer has direct access to all members of the board of directors and presents in person at board meetings twice each year.

 At the executive management and management levels, the chief information security officer leads the process of assessing and managing material risks from cybersecurity threats. Our chief information security officer has over 25 years of experience as a technology professional with in-depth knowledge of IT management processes and holds multiple degrees and professional designations, including as a certified information systems security professional (CISSP). The chief information security officer also works in collaboration with our chief information officer and chief risk officer and is supported by a cross-functional group of qualified and experienced professionals across various committees and functions. On a quarterly basis, the chief information officer provides a cybersecurity update to the disclosure committee and, on a monthly basis, the information security office team delivers a cybersecurity report to members of the senior executive team. Also refer to Item 10, Directors, Executive Officers and Corporate Governance, for additional qualification, experience and responsibility details.
 Cincinnati Financial Corporation - 2024 10-K - Page 41

 Associates involved in this area stay informed of industry trends and evolving threats using various resources including government authorities, peers, continuous education, industry publications, news outlets and other external parties that provide pertinent information. We take administrative, technical and internal accounting control measures to protect against cybersecurity incidents, including actions to monitor for, prevent, detect, mitigate and remediate any incidents that occur. These measures and actions include endpoint controls, multi-factor authentication and general cybersecurity education directed at our workforce and independent agents.

 From a monitoring perspective, generally speaking, our information security office associates monitor the environment for threats, events and potential incidents. Depending on the potential severity of any identified incident, the company's incident response process, modeled after National Institute for Standards and Technology (NIST) frameworks, is initiated. As part of this process, each incident is evaluated and inventoried by our incident response team and reported to our legal compliance subcommittee for further action. Depending on severity, certain other internal and external parties may participate in the incident response process from a compliance and financial reporting perspective.

 Incidents, regardless of severity, are evaluated and documented and are shared with the audit committee. In 2024, the audit committee received four updates on matters related to cybersecurity. The process of evaluating and documenting individual incidents, even when not deemed material, assists in determining how previous incidents have or may reasonably likely have a material effect on the company in the future.

 ITEM 7. Management's Discussion and Analysis of Financial Condition and
 Results of Operations

 Introduction
 The purpose of Management's Discussion and Analysis is to provide an understanding of Cincinnati Financial Corporation's consolidated results of operations and financial condition. Our Management's Discussion and Analysis should be read in conjunction with Item 8, Consolidated Financial Statements and related Notes. We present per share data on a diluted basis unless otherwise noted, adjusting those amounts for all stock splits and stock dividends.

 We begin with an executive summary of our results of operations, followed by other highlights and details about critical accounting estimates. In several instances, we refer to estimated industry data so that we can provide information on our performance within the context of the overall insurance industry. Unless otherwise noted, the industry data is prepared by A.M. Best, a leading insurance industry statistical, analytical and financial strength rating organization. Information from A.M. Best is presented on a statutory accounting basis for insurance company regulation in the United States of America. When we provide our results on a comparable statutory accounting basis, we label it as such; all other company data is presented in accordance with accounting principles generally accepted in the United States of America (GAAP).

 Through The Cincinnati Insurance Company, Cincinnati Financial Corporation is one of the 25 largest property casualty insurers in the nation, based on net written premium volume for the first nine months of 2024, among approximately 2,000 U.S. stock and mutual insurer groups. We market our insurance products through a select group of independent insurance agencies in 46 states as discussed in Item 1, Our Business and Our Strategy.

 The U.S. economy, the insurance industry and our company continue to face many challenges. Our long-term perspective has allowed us to address immediate challenges while also focusing on the major decisions that best position the company for success through all market cycles. We believe that this forward-looking view consistently benefits our shareholders, agents, policyholders and associates.

 To measure our progress, we have defined a measure of value creation that we believe captures the contribution of our insurance operations, the success of our investment strategy and the importance we place on paying cash dividends to shareholders. We refer to this measure as our value creation ratio (VCR) and it is made up of two primary components: (1) our rate of growth in book value per share plus (2) the ratio of dividends declared per share to beginning book value per share. This measure, intended to be all-inclusive regarding changes in book value per share, uses originally reported book value per share in cases where book value per share has been adjusted, such as after the adoption of Accounting Standards Updates with a cumulative effect of a change in accounting.

 The primary sources of our company's net income are summarized below. We discuss contributions to net income and VCR by source in Corporate Financial Highlights, followed by more detailed discussion in Financial Results.

 • Underwriting profit (loss) – Includes revenues from earned premiums for insurance and reinsurance policies or contracts, reduced by losses and loss expenses from associated insurance coverages. Those revenues are further reduced by underwriting expenses associated with marketing policies or related to administration of our insurance operations. The net result represents an underwriting profit when revenues exceed losses and expenses.
 • Investment income – Is generated primarily from investing the premiums collected for insurance policies sold, until funds are needed to pay losses for insurance claims or other expenses. Interest income from bonds or dividend income from stocks are the main categories of our investment income, with additional contribution from compounding effects over time.
 • Investment gains and losses – Occur from appreciation or depreciation of invested assets over time. Gains or losses are generally recognized from changes in market values of equity securities without a sale or when invested assets are sold or become impaired.

 We are targeting an annual value creation ratio averaging 10% to 13% over the next five-year period. At 19.8% for 2024, our performance was above the high end of that range. It was below the low end of the range for the three-year period and at the high end of the range for the five-year period, both that ended in December 2024.

 The table below shows the primary contributors of our value creation ratio on a percentage basis. Analysis of the contributors aids understanding of our financial performance. Our financial results are further analyzed in the Corporate Financial Highlights section below.

 The 2024 value creation ratio improved by 0.3 percentage points, compared with 2023, and again included a significant contribution from operating results, as shown in the table above, that was 0.8 percentage-points higher than last year. The 2024 ratio improvement from operating results was partially offset by a reduction in overall net gains from our investment portfolio and other items, including a reduction of 2.5 percentage points from our fixed-maturity securities investment portfolio. The increase in 2023, compared with 2022, was primarily due to an increase in overall net gains from our investment portfolio.

 When looking at our longer-term objectives, we see three primary performance drivers for our value creation ratio:
 • Premium growth – We believe over any five-year period our agency relationships and initiatives can lead to a property casualty written premium growth rate that exceeds the industry average. The compound annual growth rate of our net written premiums was 10.9% over the five-year period 2020 through 2024, exceeding the 7.9% estimated growth rate for the property casualty insurance industry, with 2024 representing industry data reported through the first nine months of 2024. The industry's growth rate excludes its mortgage and financial guaranty lines of business.
 • Combined ratio – We believe our underwriting philosophy and initiatives can drive performance to achieve our underwriting profitability target of a GAAP combined ratio over any five-year period that consistently averages within the range of 92% to 98% in the future. Our GAAP combined ratio averaged 94.6% over the five-year period 2020 through 2024, within the performance target range. Performance as measured by the combined ratio is discussed in Consolidated Property Casualty Insurance Results. Our statutory combined ratio averaged 94.0% over the five-year period 2020 through 2024, compared with an estimated 100.7% for the property casualty industry, with 2024 representing industry data reported through the first nine months of 2024. The industry's ratio again excludes its mortgage and financial guaranty lines of business.
 • Investment contribution – We believe our investment philosophy and initiatives can drive investment income growth and lead to a total return on our equity investment portfolio over a five-year period that exceeds the five-year total return of the S&P 500 Index.
 Investment income growth, on a pretax basis, had a compound annual growth rate of 9.7% over the five-year period 2020 through 2024.
 Over the five years ended December 31, 2024, our equity portfolio compound annual total return was 12.2% compared with a compound annual total return of 14.5% for the Index. Our equity portfolio favors larger-capitalization, high-quality, dividend-growing stocks with a slight value orientation. For the year 2024, our equity portfolio total return was 16.5%, compared with 25.0% for the Index.

 The board of directors is committed to rewarding shareholders directly through cash dividends and share repurchase authorizations. Through 2024, the company has increased the annual cash dividend rate for 64 consecutive years, a record we believe is matched by only seven other publicly traded U.S. companies.
 Cincinnati Financial Corporation - 2024 10-K - Page 47

 In addition to regular dividends, strong capital and excellent company performance has provided opportunities to further reward shareholders. The board regularly evaluates relevant factors in dividend-related decisions, and the 2024 increase to the regular dividend reflected confidence in our outstanding capital, liquidity and financial flexibility, as well as progress of our initiatives to improve earnings performance while growing insurance premium revenues. We discuss our financial position in more detail in Liquidity and Capital Resources.

 Our view of the shareholder value we can create over the next five years relies largely on three assumptions – each highly dependent on the external environment. First, we anticipate our property casualty average insurance prices will increase in proportion to, or in excess of, our loss cost trends. Second, we assume that the economy can maintain a long-term growth track. Third, we assume that valuations of our marketable securities will vary within a typical range over time, based on historical trends. If those assumptions prove to be inaccurate, we may not be able to achieve our performance targets even if we accomplish our strategic objectives.

 We discuss in Item 1A, Risk Factors, many potential risks to our business and our ability to achieve our qualitative and quantitative objectives.

We discuss our investment strategy in Item 1, Investments Segment, and results for the segment in Investments Results. Total assets increased by 11%, compared with year-end 2023. Shareholders' equity increased by 15% and book value per share increased by 16%, for reasons discussed in the preceding Executive Summary.

 The amount of our debt obligations at year-end 2024 matched year-end 2023. Our 5.5% ratio of debt to total capital (debt plus shareholders' equity) at year-end 2024 decreased by 0.8 percentage points compared with the prior-year ratio.

 Net income rose by $449 million in 2024, compared with 2023, including a $204 million increase in net investment gains on an after-tax basis. The improved 2024 net income also included an increase in property casualty underwriting income of $141 million after taxes, as discussed below, and a $104 million increase in investment income after taxes. Our investment operation's performance is discussed further in Investments Results. Net income of $1.843 billion in 2023, representing a $2.330 billion increase compared with net income for 2022, included a $2.050 billion increase in net investment gains after taxes. The improved 2023 net income also included an increase in property casualty underwriting income of $206 million after taxes and a $91 million increase in investment income after taxes.

 During 2024, 2023 and 2022, there were no material changes to our estimates for incurred losses and expenses related to the pandemic related to SARS-CoV-2, also known as COVID-19. Factors used in estimating reserves for business interruption losses or legal expenses related to the pandemic included estimates for attorney fees associated with the defense of such lawsuits filed against the company; litigation trends of such cases, including responding to amended and replead cases and cases on appeal; and trends in judicial decisions in cases filed
 Cincinnati Financial Corporation - 2024 10-K - Page 49

 against the company and other insurers. Loss experience for our insurance operations is influenced by many factors, as discussed in Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves. Also, there could be losses or legal expenses that increase due to inflation, pandemic effects or other factors.

 Property casualty net written premiums grew 15% and earned premiums grew 12% in 2024. The growth reflected average renewal price increases, premium growth initiatives and a higher level of insured exposures, including a contribution to net written premium growth of 1 percentage point from Cincinnati Re and Cincinnati Global in total. Growth in 2023 net written premiums and earned premiums was driven by factors similar to 2024. Trends and related factors are discussed in Commercial Lines, Personal Lines and Excess and Surplus Lines Insurance Results.

 Our property casualty insurance operations generated an underwriting profit for each of the three years ending in 2024. Underwriting results improved in both 2024 and 2023, compared with the respective prior-year period. For both years, the underwriting profit increase included improved overall insured loss experience before catastrophe effects, as price increases helped to offset elevated losses reflecting economic or other forms of inflation that increased our uncertainty regarding ultimate losses. Loss experience is discussed further in Financial Results for our property casualty business and related segments. The $179 million increase in 2024 underwriting profit, compared with 2023, included a $66 million increase in losses from natural catastrophe events and $27 million less benefit from net favorable reserve development on prior accident years before catastrophe losses. The $261 million increase in 2023, compared with 2022, included a $31 million increase in losses from catastrophe events and $81 million more benefit from net favorable reserve development on prior accident years before catastrophe losses.

 We measure property casualty underwriting profitability primarily by the combined ratio. Our combined ratio measures the percentage of each earned premium dollar spent on claims plus all expenses related to our property casualty operations, all on a pretax basis. A lower ratio indicates more favorable results and better underlying performance. A ratio below 100% represents an underwriting profit.

 Initiatives to improve our combined ratio are discussed in Item 1, Our Business and Our Strategy, Strategic Initiatives. In 2024, 2023 and 2022, favorable development on reserves for claims that occurred in prior accident years helped offset other incurred losses and loss expenses. Reserve development is discussed further in Property Casualty Loss and Loss Expense Obligations and Reserves. Losses from weather-related catastrophes are another important item influencing the combined ratio and are discussed along with other factors in Financial Results for our property casualty business and related segments.

 Our life insurance segment reported a profit of $57 million in 2024, $41 million in 2023 and $27 million in 2022. We discuss results for the segment in Life Insurance Results. Most of this segment's investment income is included in our investments segment results. In addition to investment income, investment gains and losses from the life insurance investment portfolio are also included in our investments segment results.

 Critical Accounting Estimates
 Cincinnati Financial Corporation's financial statements are prepared using U.S. GAAP. These principles require management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes. Actual results could differ materially from those estimates.

 The significant accounting policies used in the preparation of the financial statements are discussed in Item 8, Note 1 of the Consolidated Financial Statements. In conjunction with that discussion, material implications of uncertainties associated with the methods, assumptions and estimates underlying the company's critical accounting policies are discussed below. The audit committee of the board of directors reviews the annual financial statements with management and the independent registered public accounting firm. These discussions cover: the quality of earnings; review of reserves and accruals; reconsideration of the suitability of accounting principles; review of highly judgmental areas including critical accounting estimates; audit adjustments; and such other inquiries as may be appropriate.

 Property Casualty Insurance Loss and Loss Expense Reserves
 We establish loss and loss expense reserves for our property casualty insurance business as balance sheet liabilities. Unpaid loss and loss expenses are the estimated amounts necessary to pay for and settle all outstanding insured claims, including incurred but not reported (IBNR) claims. These reserves account for unpaid loss and loss expenses as of a financial statement date.

 For some lines of business that we write, a considerable and uncertain amount of time can elapse between the occurrence, reporting and payment of insured claims. The amount we will actually have to pay for such claims also can be highly uncertain. This uncertainty, together with the size of our reserves, makes the loss and loss expense reserves our most significant estimate. Gross loss and loss expense reserves were $9.937 billion at year-end 2024 compared with $8.975 billion at year-end 2023.

 How Reserves Are Established
 Our field claims representatives establish case reserves when claims are reported to the company to provide for our unpaid loss and loss expense obligation associated with known claims. Field claims managers supervise and review all claims with case reserves less than $100,000. Additionally, a headquarters supervisor and regional claims manager review claims under $100,000 if litigation or a certain specialty claim is involved. All claims with case reserves of $100,000 or greater are reviewed and approved by experienced headquarters supervisors and regional claims managers. Upper-level headquarters claims managers also review case reserves of $175,000 or more.

 Our claims representatives base their case reserve estimates primarily upon case-by-case evaluations that consider:
 • type of claim involved
 • circumstances surrounding each claim
 • policy provisions pertaining to each claim
 • potential for subrogation or salvage recoverable
 • general insurance reserving practices

 Case reserves of all sizes are generally reviewed on a 90-day cycle, or more frequently if new information about a loss becomes available. As part of the review process, we monitor industry trends, cost trends, relevant court cases, legislative activity and other current events in an effort to ascertain new or additional loss exposures.

 Cincinnati Financial Corporation - 2024 10-K - Page 51

 We also establish IBNR reserves to provide for all unpaid loss and loss expenses not accounted for by case reserves:
 • For events designated as natural catastrophes resulting in losses incurred related to premiums written on a direct basis by The Cincinnati Insurance Companies, we calculate IBNR reserves directly as a result of an estimated IBNR claim count and an estimated average claim amount for each event. Once case reserves are established for a catastrophe event, we reduce the IBNR reserves. Our claims department management coordinates the assessment of these events and prepares the related IBNR reserve estimates. Such an assessment involves a comprehensive analysis of the nature of the event, of policyholder exposures within the affected geographic area and of available claims intelligence. Depending on the nature of the event, available claims intelligence could include surveys of field claims representatives within the affected geographic area, feedback from a catastrophe claims team sent into the area, as well as data on claims reported as of the financial statement date.
 To determine whether an event is designated as a catastrophe, related to premiums written on a direct basis by The Cincinnati Insurance Companies, we generally use the catastrophe definition provided by Property Claims Service (PCS), a division of Insurance Services Office. PCS defines a catastrophe as an event that causes U.S., Puerto Rico and U.S. Virgin Islands damage of $25 million or more in insured property losses and affects a significant number of policyholders and insureds.
 • For events designated as natural catastrophes resulting in losses for Cincinnati Re and Cincinnati Global, we begin with a review of in-force policies, treaties and related limits likely to be affected by each event. For both Cincinnati Re and Cincinnati Global, use of information from third-party catastrophe models, industry estimates, and our own proprietary adjustments are used for the estimate of ultimate losses for each catastrophe event. Incurred losses from catastrophe events for both Cincinnati Re and Cincinnati Global can be designated catastrophes by PCS, or deemed as a catastrophe by the international insurance industry or, for Cincinnati Re, as reported by ceding companies. IBNR reserves are calculated as the difference between the estimate of the ultimate loss and loss expenses and the sum of total loss and loss expense payments and total case reserves.
 • For asbestos and environmental claims, we calculate IBNR reserves by deriving an actuarially-based estimate of total unpaid loss and loss expenses. We then reduce the estimate by total case reserves. We discuss the reserve analysis that applies to asbestos and environmental reserves in Liquidity and Capital Resources, Asbestos and Environmental Loss and Loss Expense Reserves.
 • For loss expenses that pertain primarily to salaries and other costs related to our claims associates, also referred to as adjusting and other expense or AOE, we calculate reserves based on an analysis of the relationship between paid losses and paid AOE. Reserves for AOE are allocated to company, line of business and accident year based on a claim count algorithm. Claim counts reported and used in the reserving process are primarily measured by insurance coverages that are triggered when a loss occurs and a reserve is established. Coverages are defined as unique combinations of certain attributes such as line of business and cause of loss. Claims that are opened and closed without payment are included in the reported claim counts. Claim counts are presented on a direct basis only and do not reflect any assumed or ceded reinsurance.
 • For all other claims and events, including reinsurance assumed or ceded, IBNR reserves are calculated as the difference between an actuarial estimate of the ultimate cost of total loss and loss expenses incurred reduced by the sum of total loss and loss expense payments and total case reserves estimated for individual claims. Reserve amounts for those other claims and events are significant, and represent the majority of amounts shown as IBNR reserves and loss expense reserves in the table included in Liquidity and Capital Resources, Property Casualty Loss and Loss Expense Obligations and Reserves. We discuss below the development of actuarially based estimates of the ultimate cost of total loss and loss expenses incurred.

 Our actuarial staff applies significant judgment in selecting models and estimating model parameters when preparing reserve analyses. Unpaid loss and loss expenses are inherently uncertain as to timing and amount. Uncertainties relating to model appropriateness, parameter estimates and actual loss and loss expense amounts are referred to as model, parameter and process uncertainty, respectively. Our management and actuarial staff address these uncertainties in the reserving process in a variety of ways.

 Cincinnati Financial Corporation - 2024 10-K - Page 52

 Our actuarial staff bases its IBNR reserve estimates for these losses primarily on the indications of methods and models that analyze accident year data. Accident year is the year in which an insured claim, loss or loss expense occurred. The specific methods and models that our actuaries have used for the past several years are:
 • paid and reported loss development methods
 • paid and reported loss Bornhuetter-Ferguson methods
 • individual and multiple probabilistic trend family models

 Our actuarial staff uses diagnostics to evaluate the appropriateness of the models and methods listed above. The appropriateness of these models and methods for estimating IBNR reserves tends to depend on the tail for a line of business. Tail refers to the time interval between a typical claim's occurrence and its settlement. The loss development and Bornhuetter-Ferguson methods, particularly the reported loss variations, tend to produce more appropriate IBNR reserve estimates for our short-tail lines such as homeowner and commercial property. For our mid-tail and long-tail lines, all models and methods provide useful insights.

 Our actuarial staff also devotes significant time and effort to the estimation of model and method parameters. The loss development and Bornhuetter-Ferguson methods require the estimation of numerous loss development factors. The Bornhuetter-Ferguson methods also involve the estimation of numerous expected loss ratios by accident year. Models from the probabilistic trend family require the estimation of development trends, calendar year inflation trends and exposure levels. Consequently, our actuarial staff monitors a number of trends and measures to gain key business insights necessary for exercising appropriate judgment when estimating the parameters mentioned, such as:
 • company and industry pricing
 • company and industry exposure
 • company and industry loss frequency and severity
 • past large loss events
 • company and industry premium
 • company in-force policy count

 These trends and measures also support the estimation of expected accident year loss ratios needed for applying the Bornhuetter-Ferguson methods and for assessing the reasonability of all IBNR reserve estimates computed. Our actuarial staff reviews these trends and measures quarterly, updating parameters derived from them as necessary.

 Quarterly, our actuarial staff summarizes their reserve analysis by preparing an actuarial best estimate and a range of reasonable IBNR reserves intended to reflect the uncertainty of the estimate. An inter-departmental committee that includes our actuarial management team reviews the results of each quarterly reserve analysis. The committee establishes management's best estimate of IBNR reserves, which is the amount that is included in each period's financial statements. In addition to the information provided by actuarial staff, the committee also considers factors such as:
 • large loss activity and trends in large losses
 • new business activity
 • judicial decisions
 • general economic trends such as inflation
 • trends in litigiousness and legal expenses
 • product and underwriting changes
 • changes in claims practices

 Cincinnati Financial Corporation - 2024 10-K - Page 53

 The determination of management's best estimate, like the preparation of the reserve analysis that supports it, involves considerable judgment. Changes in reserving data or the trends and factors that influence reserving data may signal fundamental shifts or may simply reflect single-period anomalies. Even if a change reflects a fundamental shift, the full extent of the change may not become evident until years later. Moreover, since our methods and models do not explicitly relate many of the factors we consider directly to reserve levels, we typically cannot quantify the precise impact of such factors on the adequacy of reserves prospectively or retrospectively.

 Due to the uncertainties described above, our ultimate loss experience could prove better or worse than our carried reserves reflect. To the extent that reserves are inadequate and increased, the amount of the increase is a charge in the period that the deficiency is recognized, raising our loss and loss expense ratio and reducing earnings. To the extent that reserves are redundant and released, the amount of the release is a credit in the period that the redundancy is recognized, reducing our loss and loss expense ratio and increasing earnings.

 Key Assumptions – Loss Reserving
 Our actuarial staff makes a number of key assumptions when using their methods and models to derive IBNR reserve estimates. Appropriate reliance on these key assumptions essentially entails determinations of the likelihood that statistically significant patterns in historical data may extend into the future. The four most significant of the key assumptions used by our actuarial staff and approved by management are:
 • Emergence of loss and defense and cost containment expenses, also referred to as DCCE, on an accident year basis. Historical paid loss, reported loss and paid DCCE data for the business lines we analyze contain patterns that reflect how unpaid losses, unreported losses and unpaid DCCE as of a financial statement date will emerge in the future. Unless our actuarial staff or management identifies reasons or factors that invalidate the extension of historical patterns into the future, these patterns can be used to make projections necessary for estimating IBNR reserves. Our actuaries significantly rely on this assumption in the application of all methods and models mentioned above.
 • Calendar year inflation. For long-tail and mid-tail business lines, calendar year inflation trends for future paid losses and paid DCCE do not vary significantly from a stable, long-term average. Our actuaries base reserve estimates derived from probabilistic trend family models on this assumption.
 • Exposure levels. Historical earned premiums, when adjusted to reflect common levels of product pricing and loss cost inflation, can serve as a proxy for historical exposures. Our actuaries require this assumption to estimate expected loss ratios and expected DCCE ratios used by the Bornhuetter-Ferguson reserving methods. They may also use this assumption to establish exposure levels for recent accident years, characterized by "green" or immature data, when working with probabilistic trend family models.
 • Claims having atypical emergence patterns. Characteristics of certain subsets of claims, such as high frequency, high severity, or mass tort claims, have the potential to distort patterns contained in historical paid loss, reported loss and paid DCCE data. When testing indicates this to be the case for a particular subset of claims, our actuaries segregate these claims from the data and analyze them separately. Subsets of claims that could fall into this category include hurricane claims or claims for other weather events where total losses we incurred were very large, individual large claims and asbestos and environmental claims.

 These key assumptions have not changed since 2005, when our actuarial staff began using probabilistic trend family models to estimate IBNR reserves.

 Paid losses, reported losses and paid DCCE are subject to random as well as systematic influences. As a result, actual paid losses, reported losses and paid DCCE are virtually certain to differ from projections. Such differences are consistent with what specific models for our business lines predict and with the related patterns in the historical data used to develop these models. As a result, management does not closely monitor statistically insignificant differences between actual and projected data.

 Cincinnati Financial Corporation - 2024 10-K - Page 54

 Reserve Estimate Variability
 Management believes that the standard error of a reserve estimate, a measure of the estimate's variability, provides the most appropriate measure of the estimate's sensitivity. The reserves we establish depend on the models we use and the related parameters we estimate in the course of conducting reserve analyses. However, the actual amount required to settle all outstanding insured claims, including IBNR claims, as of a financial statement date depends on stochastic, or random, elements as well as the systematic elements captured by our models and estimated model parameters. For the lines of business we write, process uncertainty – the inherent variability of loss and loss expense payments – typically contributes more to the imprecision of a reserve estimate than parameter uncertainty.

 Consequently, a sensitivity measure that ignores process uncertainty would provide an incomplete picture of the reserve estimate's sensitivity. Since a reserve estimate's standard error accounts for both process and parameter uncertainty, it reflects the estimate's full sensitivity to a range of reasonably likely scenarios.

 The table below provides standard errors and reserve ranges by major property casualty lines of business and in total for net loss and loss expense reserves as well as the potential effects on our net income, assuming a 21% federal tax rate. Standard errors and reserve ranges for assorted groupings of these lines of business cannot be computed by simply adding the standard errors and reserve ranges of the component lines of business, since such an approach would ignore the effects of product diversification. See Liquidity and Capital Resources, Property Casualty Loss and Loss Expense Obligations and Reserves, Range of Reasonable Reserves, for more details on our total reserve range. While the table reflects our assessment of the most likely range within which each line's actual unpaid loss and loss expenses may fall, one or more lines' actual unpaid loss and loss expenses could nonetheless fall outside of the indicated ranges.

 Life Policy and Investment Contract Reserves
 We establish the reserves for traditional life policies, including term, whole life and other products based on certain cash flow assumptions including mortality and lapse rates. These assumptions are established based on our current expectations and are reviewed annually to determine any necessary updates. They are also updated on an interim basis if evidence suggests that they should be revised. We use both our own experience and industry experience, adjusted for historical trends, in arriving at our cash flow assumptions. These reserves also include a discount rate assumption that is based on upper-medium grade fixed-income instrument yields (market value discount rates) and is updated quarterly.

 The gross reserve balance for term and whole life policy reserves was $1.456 billion, or 49.2%, of total life policy and investment contract reserves at December 31, 2024. The following table summarizes the sensitivity, on a net basis, of our term and whole life policy reserves and reinsurance recoverable amounts to hypothetical changes in key assumptions and the resulting increase/(decrease) to pretax net income and pretax other comprehensive income:

 We establish reserves for our universal life, deferred annuity and other investment contracts, equal to the cumulative account balances, which include premium deposits plus credited interest less charges and withdrawals. Charges include surrender and contract administration charges as well as asset-based fees. The reserve balance for these contracts was $1.276 billion, or 43.1%, of total life policy and investment contract reserves, at December 31, 2024.

 Some of our universal life insurance policies contain no-lapse guarantee provisions. For these policies, we establish a reserve, or other additional liability, in addition to the account balance based on expected no-lapse guarantee benefits and expected policy assessments. Key assumptions used to establish this other additional liability reserve are expected investment returns and projected lapse rates. These assumptions, and other relevant inputs, are reviewed annually and on an interim basis in line with the process described above for traditional life policies. The reserve balance was $130 million, or 4.4%, of total life policy and investment contract reserves at December 31, 2024, and is included as a component of universal life reserves in Item 8, Note 5 of the Consolidated Financial Statements.

 Asset Impairment
 Our investment portfolio is our largest asset. We monitor the fixed-maturity portfolio and all other assets for signs of credit-related or other impairment. We monitor decreases in the fair value of invested assets and the need for an allowance for credit losses for our fixed-maturity portfolio; allowances for expected credit losses on receivable and recoverable assets considering past events, current conditions and reasonable and supportable forecasts; an accumulation of company costs in excess of the amount originally expected to acquire or construct an asset; or other factors such as bankruptcy, deterioration of creditworthiness or failure to pay interest; and changes in legal factors or in the business climate.

 Cincinnati Financial Corporation - 2024 10-K - Page 56

 The application of our invested assets impairment policy resulted in write-downs of impaired securities intended to be sold that reduced our income before income taxes by less than $1 million in 2024, $4 million in 2023 and $5 million in 2022. Write-downs represent noncash charges to income and are reported as investment losses. The application of our noninvested assets impairment policy did not have a material effect on our financial condition in 2024 or 2023.

 Our internal investment portfolio managers monitor their assigned portfolios. If a fixed-maturity security is valued below amortized cost, the portfolio managers undertake additional reviews. Such declines often occur in conjunction with events taking place in the overall economy and market, combined with events specific to the industry or operations of the issuing organization. Managers review quantitative measurements such as a declining trend in fair value and the extent of the fair value decline, as well as qualitative measures such as pending events, credit ratings and issuer liquidity. We are even more proactive when these declines in valuation are greater than might be anticipated when viewed in the context of overall economic and market conditions. We provide detailed information about fixed-maturity securities fair valued in a continuous loss position at year-end 2024 in Item 7A, Quantitative and Qualitative Disclosures About Market Risk.

 An available for sale fixed maturity is impaired if the fair value of the security is below amortized cost. The impaired loss is charged to net income when we have the intent to sell the security or it is more likely than not we will be required to sell the security before recovery of the amortized cost. For impaired securities we intend to hold, an allowance for credit related losses is recorded in investment losses when the company determines a credit loss has been incurred based on certain factors such as adverse conditions, credit rating downgrades or failure of the issuer to make scheduled principal or interest payments. A credit loss is determined using a discounted cash flow analysis by comparing the present value of expected cash flows with the amortized cost basis, limited to the difference between fair value and amortized cost. Noncredit losses are recognized in other comprehensive income as a change in unrealized gains and losses on investments. We provide information about valuations of our invested assets in Item 8, Note 2 of the Consolidated Financial Statements.

 Cincinnati Financial Corporation - 2024 10-K - Page 57

 Fair Value Measurements

 Valuation of Financial Instruments
 Fair value is defined as the exit price or the amount that would be (1) received to sell an asset or (2) paid to transfer a liability in an orderly transaction between marketplace participants at the measurement date. When determining an exit price, we must, whenever possible, rely upon observable market data.

 We have categorized our financial instruments, based on the priority of the inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure the financial instruments fall within different levels of the hierarchy, the categorization is based on the lowest level that is significant to the fair value measurement of the instrument. While we consider pricing data from outside services, we ultimately determine whether the data or inputs used by these outside services are observable or unobservable.

 Financial assets and liabilities recorded in the Consolidated Balance Sheets are categorized based on the inputs to the valuation techniques as described in Item 8, Note 3 of the Consolidated Financial Statements.

 Level 1 and Level 2 Valuation Techniques
 Substantially all of the $27.665 billion of securities in our investment portfolio at year-end 2024, measured at fair value, are classified as Level 1 or Level 2. Financial assets that fall within Level 1 and Level 2 are priced according to observable data from identical or similar securities that have traded in the marketplace. Also within Level 2 are securities that are valued by outside services or brokers where we have evaluated and verified the pricing methodology and determined that the inputs are observable.

 Recent Accounting Pronouncements
 Information about recent accounting pronouncements is provided in Item 8, Note 1 of the Consolidated Financial Statements.

 Financial Results
 Consolidated financial results primarily reflect the results of our five reporting segments. These segments are defined based on financial information we use to evaluate performance and to determine the allocation of assets.
 • Commercial lines insurance
 • Personal lines insurance
 • Excess and surplus lines insurance
 • Life insurance
 • Investments

 We report as Other the noninvestment operations of the parent company and its noninsurer subsidiary, CFC Investment Company. In addition, Other includes the financial results of our reinsurance assumed operations, known as Cincinnati Re, and our London-based global specialty underwriter, known as Cincinnati Global Underwriting Ltd. SM (Cincinnati Global).

 We measure profit or loss for our commercial lines, personal lines, excess and surplus lines and life insurance segments based upon underwriting results (profit or loss), which represent net earned premium less loss and loss expenses, or contract holders' benefits incurred, and underwriting expenses on a pretax basis. We also evaluate results for our consolidated property casualty insurance operations. That is the total of our standard market segments (commercial lines and personal lines), our excess and surplus lines insurance segment, Cincinnati Re and Cincinnati Global. For analysis of our consolidated property casualty insurance results, it is important to include the earned premiums, loss and loss expenses and also underwriting expenses reported as Other. Underwriting results and segment pretax operating income are not substitutes for net income determined in accordance with GAAP.

 For our consolidated property casualty insurance operations as well as the insurance segments, statutory accounting data and ratios are key performance indicators that we use to assess business trends and to make comparisons to industry results, since GAAP-based industry data generally is not as readily available.

 Investments held by the parent company and the investment portfolios for the insurance subsidiaries are managed and reported as the investments segment, separate from our underwriting business. Net investment income and net investment gains and losses for our investment portfolios are discussed in the Investments Results.

 The calculations of segment data are described in more detail in Item 8, Note 18, of the Consolidated Financial Statements. The following sections provide analysis and discussion of results of operations for each of the five segments.

 Consolidated Property Casualty Insurance Results
 Earned and net written premiums for our consolidated property casualty operations grew in 2024, reflecting average renewal price increases, a higher level of insured exposures and strategic initiatives for targeted growth. A key measure of property casualty profitability is underwriting profit or loss. Profit increased in 2024, reflecting improved overall insured loss experience before catastrophe effects, as price increases helped to offset elevated losses reflecting economic or other forms of inflation that increased our uncertainty regarding ultimate losses. Our 2024 underwriting profit of $580 million was $179 million more than in 2023, including a $66 million unfavorable effect from a higher amount of catastrophe losses, mostly caused by severe weather. Prior accident year loss experience before catastrophes during 2024 was $27 million less favorable than in 2023. We continue working to improve underwriting profitability, such as through higher pricing and our ongoing initiatives to improve pricing precision and loss experience related to claims and loss control practices. Underwriting profit trends are discussed further below.

 The table below highlights property casualty results, with analysis and discussion in the sections that follow. That analysis and discussion includes sections by segment.

 Performance highlights for consolidated property casualty operations include:
 • Premiums – Agency renewal written premiums increased $819 million or 13% in 2024, compared with 2023, and continued to contribute to growth in earned premiums and net written premiums that rose in each of our property casualty insurance segments. The renewal premium increase was largely due to average renewal price increases and a higher level of insured exposures. Price increases with enhanced precision continue to benefit operating results.
 Cincinnati Financial Corporation - 2024 10-K - Page 60

 New business written premiums produced through agencies increased $364 million in 2024, compared with 2023. Agents appointed during 2024 or 2023 produced a 2024 increase in standard lines new business of $116 million. Growth initiatives also favorably affect growth in subsequent years, particularly as newer agency relationships mature over time.
 Cincinnati Re produced $597 million of 2024 net written premiums and contributed $39 million to growth in other written premiums, compared with 2023. Cincinnati Re assumes risks through reinsurance treaties and in some cases cedes part of the risk and related premiums to one or more unaffiliated reinsurance companies through transactions known as retrocessions. In 2024, earned premiums for Cincinnati Re totaled $573 million.
 Cincinnati Global also contributed to the increase in other written premiums. Net written premiums were $303 million in 2024, and contributed $23 million of the growth in other written premiums, compared with 2023. In 2024, earned premiums for Cincinnati Global totaled $271 million.
 Other written premiums also include premiums ceded to reinsurers as part of our ceded reinsurance program. An increase in ceded premiums, other than Cincinnati Re and Cincinnati Global premiums, reduced net written premium growth by $49 million in 2024.

 • Combined ratio – The combined ratio improved by 1.5 percentage points in 2024, compared with 2023, including a 0.2 percentage-point decrease in the ratio for catastrophe losses. The 2024 ratio for current accident year losses and loss expenses before catastrophes decreased by 1.8 percentage points. That ratio improvement included an increase of 1.4 points for the IBNR portion and a decrease of 3.2 points for the case incurred portion. Price increases and other underwriting efforts have helped to offset losses that have elevated significantly since 2021 due to inflation effects discussed below, as earned premiums in 2024 grew faster than those losses and loss expenses. The remainder of the 2024 combined ratio improvement included a decrease of 0.1 percentage points in the ratio for underwriting expenses, offset by 0.6 percentage points less benefit in the ratio for prior accident year losses and loss expenses before catastrophes. We further discuss ratios related to reserve development in the sections that follow the Catastrophe Losses Incurred table below.
 Elevated inflation since 2021 has resulted in higher losses and loss expenses as costs have increased significantly to repair damaged autos or other property that we insure. We also experienced higher losses for liability coverages for some of our lines of business. Higher losses and loss expenses for various lines of business reflect increased uncertainty of estimated ultimate losses. Until longer-term paid loss cost trends become more clear, we intend to remain prudent in reserving for estimated ultimate losses. We believe future property casualty underwriting results will continue to benefit from price increases and our ongoing initiatives to improve pricing precision and loss experience related to claims and loss control practices.
 Our statutory combined ratio was 92.9% in 2024 compared with 94.6% in 2023 and 97.7% in 2022. The estimated statutory combined ratio for the property casualty industry, with the industry's ratio excluding its mortgage and financial guaranty lines of business and based on industry data reported through the first nine months of 2024, was 97.9% in 2024, 103.7% in 2023 and 103.1% in 2022. The contribution of catastrophe losses to our statutory combined ratio was 8.4 percentage points in 2024, 8.8 percentage points in 2023 and 8.9 percentage points in 2022, compared with industry estimates of 8.8, 7.8 and 6.7 percentage points, respectively, with 2024 representing industry data reported through the first nine months of 2023. Components of the combined ratio are discussed below.
 Catastrophe loss trends are an important factor in assessing trends for overall underwriting results. Our 10-year historical annual average contribution of catastrophe losses to the combined ratio was 8.0 percentage points at December 31, 2024. Our five-year average was 9.2 percentage points.

 Cincinnati Financial Corporation - 2024 10-K - Page 61

 Effective June 1, 2024, we restructured our reinsurance program for Cincinnati Re only, providing retrocession coverages with various triggers, exclusions and unique features. The program included property catastrophe excess of loss coverage with a total available aggregate limit of $60 million in excess of $80 million per occurrence. During 2024, there was no recovery from reinsurers for losses pertaining to this program. See Item 7, Liquidity and Capital Resources, 2025 Reinsurance Ceded Programs, for a discussion of other reinsurance coverage.

 The following table shows catastrophe losses incurred for the past two calendar years, net of reinsurance, as well as the effect of loss development on prior period catastrophe reserves. We individually list declared catastrophe events for which our incurred losses reached or exceeded $25 million.

 Consolidated Property Casualty Insurance Loss and Loss Expenses
 Loss and loss expenses include both net paid losses and reserve changes for unpaid losses as well as the associated loss expenses. For all property casualty lines of business in aggregate, net loss and loss expense reserves at December 31, 2024, were $1.055 billion higher than at year-end 2023, including $998 million for incurred but not reported (IBNR) reserves. The $1.055 billion reserve increase raised year-end 2023 net loss and loss expense reserves by 12%, matching a 12% increase in 2024 earned premiums.

 Most of the incurred losses and loss expenses shown in the consolidated property casualty insurance results three-year highlights table are for the respective current accident years, with reserve development on prior accident years shown separately. Since less than half of our consolidated property casualty current accident year incurred losses and loss expenses represents net paid amounts, the majority represents reserves for our estimate of ultimate losses and loss expenses. These reserves develop over time, and we re-estimate previously reported reserves as we learn more about the development of the related claims. The table below illustrates that development. For example, the 67.7% accident year 2023 loss and loss expense ratio reported as of December 31, 2023, developed favorably by 4.9 percentage points to 62.8% due to claims settling for less than previously estimated, or due to updated reserve estimates for unpaid claims, as of December 31, 2024. Accident years 2023 and 2022 have both developed favorably, as indicated by the progression over time for the ratios in the table.

 Catastrophe loss trends, discussed above, accounted for some of the movement in the current accident year loss and loss expense ratio for 2024, compared with 2023. Catastrophe losses added 9.6 percentage points in 2024, 9.3 points in 2023 and 10.2 points in 2022 to the respective consolidated property casualty current accident year loss and loss expense ratios in the table above.

 The 56.6% ratio for current accident year loss and loss expenses before catastrophe losses for 2024 decreased 1.8 percentage points compared with the 58.4% accident year 2023 ratio measured as of December 31, 2023. The decrease included a 1.4 percentage-point decrease in the ratio for current accident year losses of $2 million or more per claim, shown in the table below.

 Reserve development on prior accident years continued to net to a favorable amount in 2024, and was primarily due to less-than-anticipated loss emergence on known claims. We recognized $236 million of favorable development in 2024, compared with $215 million in 2023 and $159 million in 2022. Of the $21 million increase in 2024, compared with 2023, $19 million was attributable to our commercial property line of business. Approximately 89% of our net favorable reserve development on prior accident years recognized during 2024 occurred in our workers' compensation, commercial property and homeowner lines of business. In 2023, our workers' compensation, commercial property and homeowner lines of business were responsible for approximately 80% of the favorable reserve development. As discussed in Liquidity and Capital Resources, Property Casualty Loss and Loss Expense Obligations and Reserves, Property Casualty Insurance Development of Estimated Reserves by Accident Year, commercial casualty and workers' compensation are considered long-tail lines with the potential for revisions inherent in estimating reserves. Favorable development recognized during 2022 was primarily from our workers' compensation and homeowner lines of business. Development by accident year is further discussed in Liquidity and Capital Resources, Property Casualty Insurance Development of Estimated Reserves by Accident Year.

 In 2024, total large losses incurred decreased by $98 million, or 26%, net of reinsurance, primarily due to a decrease for our commercial lines insurance segment. The corresponding 2024 ratio decreased 1.7 percentage points, compared with 2023. The large loss data included in the table above does not include Cincinnati Re and Cincinnati Global. Our analysis of large losses incurred indicated no unexpected concentration of these losses and reserve increases by geographic region, policy inception, agency or field marketing territory. We believe the inherent volatility of aggregate loss experience for our portfolio of larger policies is greater than that of our portfolio of smaller policies, and we continue to monitor the volatility in addition to general inflationary trends in loss costs.

 Consolidated property casualty commission expenses rose $167 million, or 12%, in 2024, with profit-sharing commissions for agencies increasing by $18 million. The 2024 ratio of commission expenses as a percent of earned premiums decreased by 0.1 percentage points, compared with 2023. The ratio for 2023 decreased compared with 2022. In 2024, other underwriting expenses as a percent of earned premiums matched 2023, as earned premiums kept pace with other underwriting expenses. In 2023, other underwriting expenses as a percent of earned premiums increased, compared with 2022, as earned premiums rose at a slower pace than other underwriting expenses. The three-year period ending in 2024 also included ongoing expense management efforts.

 Commission expenses include our profit-sharing commissions, which are primarily based on one-year and three-year profitability of an agency's business. The aggregate profit trend for agencies that earn these profit-based commissions can differ from the aggregate profit trend for all agencies reflected in our consolidated property casualty results.

 Salaries, benefits and payroll taxes for our associates account for approximately half of our property casualty other underwriting expenses. Most of our associates either provide direct service to the property casualty portion of our agencies' businesses or provide support to those associates.

 Discussions below of our property casualty insurance segments provide additional details about our results.

 Performance highlights for the commercial lines insurance segment include:
 • Premiums – Earned premiums and net written premiums rose in 2024, including a $211 million, or 5%, increase in renewal written premiums that continued to include higher average pricing and a higher level of insured exposures. New business written premiums in 2024 increased $157 million, or 27%, compared with 2023, as we continued to carefully underwrite each policy in a highly competitive market.
 • Combined ratio – The 2024 combined ratio improved by 3.0 percentage points compared with 2023, including a 1.8 percentage-point decrease in the ratio component for catastrophe losses. The 2024 combined ratio also improved by 1.5 points due to a lower ratio for current accident year loss and loss expenses before catastrophe losses, compared with 2023. That ratio improvement included an increase of 2.9 points for the IBNR portion and a decrease of 4.4 points for the case incurred portion. Price increases and other underwriting actions have helped offset losses that have elevated significantly since 2021 due to inflation effects, as earned premiums in 2024 grew faster than those losses and loss expenses. Development on prior accident years loss and loss expense reserves before catastrophes during 2024 was 0.2 percentage points less favorable than in 2023, as discussed below.
 When estimating the ultimate cost of total loss and loss expenses, we consider many factors, including trends for inflation, historical paid and reported losses, large loss activity and other data or information for the industry or our company. Elevated inflation since 2021 has resulted in higher losses and loss expenses as costs have increased significantly to repair damaged business property or autos that we insure, in addition to higher losses for liability coverages for some of our lines of business. Due to increased uncertainty regarding ultimate losses, we intend to remain prudent in reserving for estimated ultimate losses until longer-term loss cost trends become more clear.

 Pricing precision and other initiatives to improve commercial lines underwriting profitability complement our business practices that continue to leverage the local presence of our field associates. Field marketing representatives meet with local agencies to assess each risk, determine limits of insurance and establish appropriate terms and conditions. They underwrite new business, with collaboration and expertise from headquarters associates as needed, while field loss control, machinery and equipment and claims representatives conduct on-site inspections. Field claims representatives also assist underwriters by preparing full reports on their first-hand observations of risk quality.
 Our commercial lines statutory combined ratio was 92.2% in 2024, compared with 95.6% in 2023 and 98.5% in 2022. The contribution of catastrophe losses to our commercial lines statutory combined ratio was 5.4 percentage points in 2024, 7.2 percentage points in 2023 and 7.0 percentage points in 2022.

 We continue to refine our use of predictive analytics tools to improve pricing precision as we further segment commercial lines policies, emphasizing identification and retention of policies we believe have relatively stronger price adequacy. These tools better align individual insurance policy pricing to risk attributes, providing our underwriters with enhanced abilities to target profitability and to discuss pricing impacts with our agencies. We also continue to leverage our local relationships with agents through the efforts of our teams that work closely with them. We believe our field focus is unique and has several advantages, including providing us with quality intelligence on local market conditions. We seek to maintain appropriate pricing discipline for both new and renewal business as management continues to emphasize the importance of our agencies and underwriters assessing account quality to make careful decisions on a case-by-case basis whether to write new business or renew a policy. Premium rate credits may be used to retain renewals of quality business and to earn new business, but we do so selectively in order to avoid commercial accounts that we believe have insufficient profit margins.

 Our 5% increase in 2024 agency renewal written premiums included higher average pricing. We measure average changes in commercial lines renewal pricing as the rate of change in renewal premium for the new policy period compared with the premium for the expiring policy period, assuming no change in the level of insured exposures or policy coverage between those periods for respective policies. In 2024, our standard commercial lines policies averaged an estimated pricing change at a percentage near the low end of the high-single-digit range. Our average commercial lines pricing change includes the flat pricing effect of certain coverages within package policies written for a three-year term that were in force but did not expire during the period being measured. Therefore, the average commercial lines pricing change we report reflects a blend of policies that did not expire and other policies that did expire during the measurement period.

 Cincinnati Financial Corporation - 2024 10-K - Page 67

 For only those commercial lines policies that did expire and were then renewed during 2024, we estimate that the average price increase was at a percentage in the high-single-digit range. During 2024, we continued to further segment our commercial lines policies, emphasizing identification and retention of policies we believed had relatively stronger price adequacy. Conversely, we continued to seek more aggressive renewal terms and conditions on policies we believed had relatively weaker pricing, in turn retaining fewer of those policies.

 Our 2024 increase of 5% for the commercial lines segment's agency renewal written premiums also included a higher level of insured exposures, in addition to other factors such as changes in policy retention rates or changes in mix of business that can cause variations in average premiums per policy. Part of the insured exposure increase reflects our response to inflation effects that increase the cost of building materials to repair damaged commercial structures. We use building valuation software to automate much of that underwriting process and may also manually adjust premiums to reflect property costs.

 Changes in the economy can affect insured exposures that directly relate to premium amounts charged for some policies. For commercial accounts, we usually calculate initial estimates for general liability premiums based on estimated sales or payroll volume, while we calculate workers' compensation premiums based on estimated payroll volume. A change in sales or payroll volume generally indicates a change in demand for a business's goods or services, as well as a change in its exposure to risk. Policyholders who experience sales or payroll volume changes due to economic factors may also have other exposures requiring insurance, such as commercial auto or commercial property. Premium levels for these other types of coverages generally are not linked directly to sales or payroll volumes.

 Premiums resulting from audits of actual sales or payrolls that confirmed or adjusted initial premium estimates are part of net written premiums and earned premiums. They also contribute to increases or decreases in our agency renewal written premiums. The contribution to our commercial lines earned premiums was $107 million, $157 million and $127 million in 2024, 2023 and 2022, respectively. The contribution on a net written premium basis was $108 million, $136 million and $101 million in 2024, 2023 and 2022, respectively. These net written premium amounts are included with agency renewal written premiums in the Commercial Lines Insurance Premiums table above.

 In 2024, our commercial lines new business premiums written by our agencies increased $157 million, or 27%, compared with 2023, as we continued to carefully underwrite each policy in a highly competitive market. New business premium volume in recent years has been significantly influenced by new agency appointments. Agencies appointed since the beginning of 2023 produced commercial lines new business written premiums of $72 million, in aggregate, during 2024, up $56 million from what they produced during 2023. All other agencies contributed the remaining $669 million, up $101 million from the $568 million they produced in 2023.

 For new business, our field associates are frequently meeting with our agents to: help judge the quality of each account; emphasize the Cincinnati value proposition; call on sales prospects with those agents; and provide appropriate quotes after carefully evaluating risk exposures. Some of our new business comes from accounts that are not new to the agent. We believe these seasoned accounts tend to be priced more accurately than business that is new to us and the agency. As we appoint new agencies who choose to move accounts to us, we report these accounts as new business to us.

 Other written premiums primarily consist of premiums that are ceded to reinsurers and lower our net written premiums. An increase in ceded premiums reduced net written premium growth by $20 million in 2024.

 Commercial Lines Insurance Loss and Loss Expenses
 Loss and loss expenses include both net paid losses and reserve changes for unpaid losses as well as the associated loss expenses. Most of the incurred losses and loss expenses shown in the commercial lines insurance segment three-year highlights table are for the respective current accident years, with reserve development on prior accident years shown separately. Since less than half of our commercial lines insurance segment current accident year incurred losses and loss expenses represents net paid amounts, the majority represents reserves for our estimate of ultimate losses and loss expenses. These reserves develop over time, and we re-estimate previously reported reserves as we learn more about development on the related claims. The table below illustrates that development. For example, the 68.2% accident year 2023 loss and loss expense ratio reported as of December 31, 2023, developed favorably by 5.0 percentage points to 63.2% due to claims settling for less than previously estimated, or due to updates to reserve estimates for unpaid claims, as of December 31, 2024. Accident years 2023 and 2022 for the commercial lines insurance segment have both developed favorably, as indicated by the progression over time of the ratios in the table.

 Catastrophe losses, as discussed in Consolidated Property Casualty Insurance Results, explain some of the movement in the current accident year loss and loss expense ratio for accident year 2024, compared with 2023. Catastrophe losses added 6.1 percentage points in 2024, 7.4 points in 2023 and 7.6 points in 2022 to the respective commercial lines current accident year loss and loss expense ratios in the table above.

 The 59.3% ratio for current accident year loss and loss expenses before catastrophe losses for 2024 decreased 1.5 percentage points compared with the 60.8% accident year 2023 ratio measured as of December 31, 2023. The change included a decrease in large losses incurred, described below including a table with corresponding ratios for new losses above $2 million, with a 2.2 percentage-point decrease in the 2024 ratio. Contributions to the ratio decrease included inflation effects that were offset by the favorable impact from various initiatives, such as those to improve pricing precision, risk selection and loss experience related to claims and loss control practices.

 Commercial lines reserve development on prior accident years of $138 million in 2024 continued to net to a favorable amount and provided a larger benefit than the $123 million recognized in 2023. The $15 million net increase in 2024, compared with 2023, included $19 million from our commercial property line of business and $17 million from our workers' compensation line of business, partially offset by an $11 million decrease from our commercial casualty line of business. Most of our commercial lines net favorable reserve development on prior accident years recognized during 2024 occurred in our workers' compensation and commercial property lines of business. Favorable development recognized during 2023 and 2022 was also mostly from our workers' compensation and commercial property lines of business. As discussed in Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves, stable paid and reported loss patterns are a key assumption used to make projections necessary for estimating IBNR reserves. Development by accident year and other trends for commercial lines loss and loss expenses and the related ratios are further discussed in Liquidity and Capital Resources, Property Casualty Insurance Development of Estimated Reserves by Accident Year.

 In 2024, total large losses incurred decreased by $103 million, or 35%, net of reinsurance. The corresponding 2024 ratio decreased 2.6 percentage points, compared with 2023. The 2024 decrease on a dollar basis was primarily due to a decrease of $116 million for our commercial property line of business. In 2023, total large losses incurred and the corresponding ratio were higher than in 2022, largely due to higher amounts of large losses for our commercial property line of business. Our analysis indicated no unexpected concentration of these losses and reserve increases by geographic region, policy inception, agency or field marketing territory. We believe the inherent volatility of aggregate loss experience for our portfolio of larger policies is greater than that of our portfolio of smaller policies, and we continue to monitor the volatility in addition to general inflationary trends in loss costs.

 Commercial lines commission expenses as a percent of earned premiums decreased slightly in 2024, compared with 2023, reflecting a decrease in the ratio for profit-sharing commissions for agencies. The ratio for 2023 decreased slightly compared with 2022. In 2024, other underwriting expenses as a percent of earned premiums increased, compared with 2023, as earned premiums rose at a slower pace than other underwriting expenses, primarily employee-related expenses. In 2023, other underwriting expenses as a percent of earned premiums increased, compared with 2022, as earned premiums rose at a slower pace than other underwriting expenses. The three-year period ending in 2024 also included ongoing expense management efforts.

 Commercial Lines Insurance Outlook
 Renewal and new business pricing for commercial risks continues to experience significant inflationary and competitive pressure, and we continue to respond with enhanced pricing analytics and careful risk selection. We are committed to our agencies and focus on a long-term strategy when considering how to successfully navigate changing, and often challenging, market pressures and conditions while profitably growing our commercial lines insurance segment.

 We intend to grow through additional agency appointments, expansion of our local field presence, enhanced expertise and product expansion that meets the needs of an even larger percentage of our agencies' total commercial portfolio. Our goal is to provide flexibility in our process so that we can deliver an industry-leading agency experience to all of our agents as we work to be the first and last solution when they are considering business placement.

 We intend to keep marketing our products to a broad range of business classes with a total account approach, while also continuing to diversify our book of business. Work continues to improve our pricing precision and further segment commercial risks as underwriters emphasize underwriting discipline and careful management of rate levels. They seek to accurately match exposures with appropriate premiums, evaluating each risk on a policy-by-policy basis for decisions about rates, terms and conditions based on each account's individual characteristics. We believe that our initiatives to improve pricing precision and lower loss costs will continue to benefit commercial lines profitability during 2025.

 Performance highlights for the personal lines insurance segment include:
 • Premiums – Earned premiums and net written premiums continued to grow in 2024, due to increases in new business written premiums and renewal written premiums that included higher average pricing and a higher level of insured exposures. Renewal written premiums rose $538 million, or 27%, in 2024, compared with 2023, while new business written premiums rose $188 million, or 45%. Cincinnati Private ClientSM net written premiums, included in the personal lines insurance segment, rose $462 million, or 37%, to approximately $1.719 billion in 2024, representing 57.3% of the segment's 2024 net written premiums. Cincinnati Private Client net written premiums included excess and surplus lines homeowner policies with premiums totaling $166 million in 2024 and $109 million in 2023.
 • Combined ratio – The 2024 combined ratio improved by 2.9 percentage points, compared with 2023, including a decrease of 1.2 points in the ratio for catastrophe losses. The improvement also included 2.5 points from a lower ratio for current accident year loss and loss expenses before catastrophe losses. That ratio decrease included an increase of 2.0 points for the IBNR portion and a decrease of 4.5 points for the case incurred portion. Price increases and other underwriting efforts have helped to offset losses that have elevated significantly since 2021 due to inflation effects, as earned premiums in 2024 grew faster than those losses and loss expenses. The ratio decreases for catastrophe losses and current accident year results were partially offset by an increase of 1.7 points from reserve development on prior accident year loss and loss expenses before catastrophes during 2024 that was unfavorable by 0.7 points compared with favorable development of 1.0 points in 2023.
 When estimating the ultimate cost of total loss and loss expenses, we consider many factors, including trends for inflation, historical paid and reported losses, large loss activity and other data or information for the industry or our
 Cincinnati Financial Corporation - 2024 10-K - Page 72

 company. Elevated inflation since 2021 has resulted in higher losses and loss expenses as costs have increased significantly to repair damaged autos or homes that we insure, in addition to higher losses for liability coverages for some of our lines of business. Due to increased uncertainty regarding ultimate losses, we intend to remain prudent in reserving for estimated ultimate losses until longer-term loss cost trends become more clear.
 We have increased our pricing precision and implemented numerous rate increases in recent years to improve our personal lines insurance segment results. In addition, we have made greater use of higher minimum loss deductibles and enhanced our property inspection processes to verify condition and insurance to value. We have worked to improve our geographic diversification by expanding our personal lines operation to additional states as the type of catastrophe risk can vary by state.
 Our personal lines statutory combined ratio was 95.5% in 2024, compared with 98.3% in 2023 and 97.7% in 2022. The contribution of catastrophe losses to our personal lines statutory combined ratio was 13.9 percentage points in 2024, 15.1 percentage points in 2023 and 11.4 percentage points in 2022.

 Personal lines insurance is a strategic component of our overall relationship with most of our agencies and is an important component of our agencies' relationships with their clients. We believe agents recommend our personal insurance products to their clients who seek to balance quality and price and who are attracted by our superior claims service and the benefits of our package approach. We also believe our continuing efforts to improve pricing precision are helping us attract and retain more of our agencies' preferred business, while also obtaining higher rates for more thinly priced business.

 The 27% increase in agency renewal written premiums in 2024 included the effect of various rate changes. We estimate that premium rates for our personal auto line of business increased at an average percentage in the low-double-digit range during 2024, with some individual policies experiencing lower or higher rate changes based on enhanced pricing precision enabled by predictive models that consider characteristics of specific risks. For our homeowner line of business, we estimate that price increases during 2024 averaged a percentage in the high-single-digit range. Similar to our personal auto line of business, that average varied widely by state, and some individual policies experienced lower or higher rate changes based on pricing precision and current rate level indications that helped determine appropriate premium rates.

 The increase in agency renewal written premiums in 2024 also included a higher level of insured exposures and other factors such as changes in policy deductibles or mix of business. Part of the insured exposure increase reflects our response to inflation effects that increase the cost of building materials to repair damaged homes.

 Personal lines new business written premiums grew by $188 million, or 45%, during 2024, compared with 2023, including approximately $89 million from Cincinnati Private Client policies and $99 million from middle-market policies. We believe we maintained underwriting and pricing discipline across all personal lines markets as we expanded use of enhanced pricing precision tools. Some of what we report as new business came from accounts that were not new to our agents. We believe our agents' seasoned accounts tend to be priced more accurately than business that may be less familiar to them.

 Other written premiums primarily consist of premiums that are ceded to reinsurers and lower our net written premiums. An increase in ceded premiums reduced net written premium growth by $28 million in 2024.

 Personal Lines Insurance Loss and Loss Expenses
 Loss and loss expenses include both net paid losses and reserve changes for unpaid losses as well as the associated loss expenses. Most of the incurred losses and loss expenses shown in the personal lines insurance segment three-year highlights table are for the respective current accident years, with reserve development on prior accident years shown separately. Since approximately two-thirds of our personal lines current accident year incurred losses and loss expenses represent net paid amounts, the remaining one-third represents reserves for our estimate of ultimate losses and loss expenses. These reserves develop over time, and we re-estimate previously reported reserves as we learn more about the development on the related claims. The table below illustrates that development. For example, the 73.7% accident year 2023 loss and loss expense ratio reported as of December 31, 2023, developed favorably by 2.6 percentage points to 71.1% due to claims settling for less than previously estimated, or due to updated reserve estimates for unpaid claims, as of December 31, 2024. Accident year 2022 for the personal lines segment developed favorably for the two-year period ending December 31, 2024, as indicated by the progression over time for the ratios in the table. It experienced a small amount of unfavorable development during 2024, driven by the personal auto line of business as described below, and favorable development during 2023.

 Catastrophe losses, as discussed in Consolidated Property Casualty Insurance Results, explain some of the movement in the current accident year loss and loss expense ratio for accident year 2024, compared with accident year 2023. Catastrophe losses added 15.6 percentage points in 2024, 17.3 points in 2023 and 14.0 points in 2022 to the respective personal lines current accident year loss and loss expense ratios in the table above. Personal lines catastrophe losses for 2024 resulted in a ratio higher than our 11.4% 10-year annual average for personal lines. Personal lines catastrophe losses are inherently volatile, as discussed above and in Consolidated Property Casualty Insurance Results.

 The 53.9% ratio for current accident year loss and loss expenses before catastrophe losses for 2024 improved 2.5 percentage points compared with the 56.4% accident year 2023 ratio measured as of December 31, 2023. The decrease included an improvement in the ratios for new losses above $2 million, with a 0.7 percentage-point decrease in the 2024 ratio. Other contributions included inflation effects that were offset by the favorable impact from various initiatives, such as those to improve pricing precision, risk selection and loss experience related to claims and loss control practices.

 Personal lines loss and loss expense reserve development on prior accident years recognized in 2024 was favorable by $26 million, in aggregate, compared with $64 million in 2023. The 2024 net favorable reserve development included $54 million for our homeowner line of business offset by $20 million of unfavorable development for our personal auto line of business. The 2023 net favorable reserve development included $53 million for our homeowner line of business and $15 million for our personal auto line of business. As discussed in Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves, stable paid and reported loss patterns are a key assumption used to make projections necessary for estimating IBNR reserves. Development by accident year and other trends for personal lines loss and loss expenses and the related ratios are further discussed in Liquidity and Capital Resources, Property Casualty Insurance Development of Estimated Reserves by Accident Year.

 In 2024, personal lines total large losses incurred decreased by $1 million, or 1%, net of reinsurance. The corresponding 2024 ratio decreased 0.9 percentage points, compared with 2023. The 2024 decrease was primarily due to a lower amount for our homeowner line of business. In 2023, total large losses increased, compared with 2022, primarily due to higher amounts for our homeowner line of business. Our analysis indicated no unexpected concentration of these losses and reserve increases by risk category, geographic region, policy inception, agency or field marketing territory. We believe the inherent volatility of aggregate loss experience for our portfolio of larger policies is greater than that of our portfolio of smaller policies, and we continue to monitor the volatility in addition to general inflationary trends in loss costs.

 Personal lines commission expense as a percent of earned premiums decreased slightly in 2024 compared with 2023, as earned premiums rose at a faster pace than commission expenses. The ratio for 2023 decreased slightly compared with 2022, as earned premiums rose at a faster pace than commission expenses. Other underwriting expenses as a percent of earned premiums in 2024 decreased, compared with 2023, reflecting ongoing expense management efforts, as premium growth outpaced growth in other underwriting expenses. In 2023, other underwriting expenses as a percent of earned premiums matched the 2022 percentage, reflecting ongoing expense management efforts, as the pace of premium growth was in line with growth in other expenses.

 Personal Lines Insurance Outlook
 The personal lines market of the U.S. property casualty industry continued to experience challenges in 2024, including elevated inflation, increasing loss costs and pricing pressures as insurers pursued rate adequacy. Our response continues to include rate increases, pricing precision for individual risks and use of inflation factors that respond to higher costs to repair property. We believe we can continue to profitably grow premiums in our personal lines insurance segment through new agency appointments and an ongoing focus on diversification of product and geography. We serve middle market, mass affluent and high net worth clients, helping us grow across the U.S. and spreading our catastrophe risk. Drivers of profitable growth for our Cincinnati Private Client business also include selectively using non-admitted insurance property forms and rates in certain catastrophe-prone states and geographies.

 Our high net worth initiative, along with various other actions to improve performance in our personal lines insurance segment, is discussed in greater detail in Personal Lines Insurance Results and also in Item 1, Our Business and Our Strategy, Strategic Initiatives and Our Segments, Personal Lines Insurance Segment.

 Our excess and surplus lines insurance segment includes results of The Cincinnati Specialty Underwriters Insurance Company and CSU Producer Resources Inc. Performance highlights for this segment include:
 • Premiums – Earned premiums and net written premiums continued to grow during 2024, primarily due to higher renewal written premiums that included average renewal estimated price increases in the high-single-digit range. New business written premiums rose 11% in 2024, compared with 2023, and also contributed to premium growth.
 • Combined ratio – The combined ratio increased by 3.4 percentage points in 2024, compared with 2023, primarily due to unfavorable reserve development on prior accident year loss and loss expenses that offset a lower ratio for current accident year loss and loss expenses before catastrophe losses. Approximately 89% of our 2024 earned premiums for the excess and surplus lines insurance segment provided commercial casualty coverages for various insured liability claims that have experienced higher losses reflecting elevated inflation. Due to uncertainty regarding ultimate losses, we intend to remain prudent in reserving for estimated ultimate losses until longer-term loss cost trends become more clear. The higher 2024 combined ratio also included increases in ratios for underwriting expenses and catastrophe losses.

 The $70 million increase in 2024 renewal premiums largely reflected higher renewal pricing. Average renewal estimated price increases were in the high-single-digit range during 2024. We measure average changes in excess and surplus lines renewal pricing as the rate of change in renewal premium for the new policy period compared with the premium for the expiring policy period, assuming no change in the level of insured exposures or policy coverage between those periods for respective policies.

 New business written premiums in 2024 grew by $19 million, or 11%, compared with 2023, as we continued to carefully underwrite each policy in a highly competitive market. Other written premiums in 2024 reduced net written premium growth by $5 million more than in 2023 and are primarily premiums that are ceded to reinsurers and therefore reduce our net written premiums.

 Excess and Surplus Lines Loss and Loss Expenses
 Loss and loss expenses include both net paid losses and reserve changes for unpaid losses, as well as the associated loss expenses. The majority of the total incurred losses and loss expenses shown above in the three-year highlights table are for the respective current accident years, with reserve development on prior accident years shown separately. Since less than 20% of our excess and surplus lines current accident year incurred losses and loss expenses represents net paid amounts, a large majority represents reserves for our estimate of unpaid losses and loss expenses. These reserves develop over time, and we update our estimates of previously reported reserves as we learn more about the development on the related claims. The table below illustrates that development. For example, the 66.6% accident year 2023 loss and loss expense ratio reported as of December 31, 2023, developed favorably by 10.5 percentage points to 56.1% due to claims settling for less than previously estimated, or due to updated reserve estimates for unpaid claims, as of December 31, 2024. Accident year 2022 for the segment developed favorably for the two-year period ending December 31, 2024, as indicated by the progression over time for the ratios in the table. It experienced unfavorable development during 2024 and favorable development during 2023.

 Catastrophe losses, as discussed in Consolidated Property Casualty Insurance Results, explain some of the movement among components of the current accident year loss and loss expense ratio for accident year 2024, compared with 2023. Catastrophe losses added 1.3 percentage points in 2024, 0.7 points in 2023 and 1.0 points in 2022 to the respective excess and surplus lines current accident year loss and loss expense ratios in the table above.

 The 64.2% ratio for current accident year loss and loss expenses before catastrophe losses for 2024 improved by 1.7 percentage points compared with the 65.9% accident year 2023 ratio measured as of December 31, 2023. The improvement was partially offset by a 0.7 percentage-point increase in the ratio for current accident year losses of $2 million or more per claim, shown in the table below.

 Cincinnati Financial Corporation - 2024 10-K - Page 78

 Excess and surplus lines reserve development on prior accident years was a net unfavorable $8 million for 2024 and a net favorable $11 million for 2023. The net unfavorable amount for 2024 was primarily for accident years 2021 and prior and was due primarily to higher-than-anticipated loss emergence on known claims.

 We believe the loss and loss expense reserves for our excess and surplus lines business are adequate. The amount of outstanding reserves for our excess and surplus lines operation can be seen in a table in Liquidity and Capital Resources, Property Casualty Loss and Loss Expense Obligations and Reserves. One indication of how long it takes for most of the outstanding reserves to be settled is to measure outstanding reserves by accident year at different points in time, using Item 8, Note 4 of the Consolidated Financial Statements. For example, for accident years 2017, 2016 and 2015, in aggregate, after subtracting cumulative paid amounts from incurred amounts at December 31, 2017, reserves for estimated unpaid losses, plus the portion of loss expenses known as ALAE, equaled $203 million. For those same accident years, at December 31, 2024, the reserve estimate for the remaining unpaid amount equaled $18 million. As discussed in Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves, stable paid and reported loss patterns are a key assumption used to make projections necessary for estimating IBNR reserves. The inherent uncertainty in estimating reserves is discussed in Liquidity and Capital Resources, Property Casualty Insurance Loss and Loss Expense Obligations and Reserves. Development trends by accident year are further discussed in Property Casualty Insurance Development of Estimated Reserves by Accident Year.

 In 2024, total large losses increased by $6 million, net of reinsurance. The ratio for 2024 large losses as a percent of earned premiums increased by 1.0 percentage points, compared with 2023. That ratio for 2023 decreased by 0.7 points, compared with 2022. Our analysis indicated no unexpected concentration of these losses and reserve increases by risk category, geographic region, policy inception, agency or field marketing territory. We believe the inherent volatility of aggregate loss experience for our portfolio of larger policies is greater than that of our portfolio of smaller policies, and we continue to monitor the volatility in addition to general inflationary trends in loss costs.

 Excess and surplus lines commission expense as a percent of earned premiums for 2024 increased compared with 2023, primarily from an increase in the ratio for profit-sharing commissions for agencies. The ratio for 2023 increased compared with 2022, including increases in the ratios for reinsurance commissions and profit-sharing commissions for agencies. The ratio for other underwriting expenses increased in 2024 largely due to increases in employee-related expenses. The ratio for other underwriting expenses increased slightly in 2023. The three-year period ending in 2024 also reflected ongoing expense management efforts and changes in the pace of premium growth.

 Excess and Surplus Lines Insurance Outlook
 The excess and surplus lines market is expected to see the magnitude of rate increases moderate for property-driven risks, except for catastrophe exposures, according to industry publications. For casualty-driven risks, premium rates in the foreseeable future are expected to be firm, primarily driven by social inflation and litigation funding impacts. New business opportunities are expected to increase as standard market insurance companies continue to re-underwrite business they previously took from the excess and surplus lines market and as larger excess and surplus lines companies re-underwrite their business with an emphasis on underwriting profitability.

 Industry reports continue to suggest that there are opportunities for profitability and growth through greater use of technology. Technology and data are also being used by excess and surplus lines insurance companies to identify new exposures in emerging businesses that need insurance protection or other value-added services. We have implemented artificial intelligence technology that has reduced data entry time and improved the quality of our data analytics and expect ongoing benefits in the future.

 As we continue to execute our strategy of providing superior service, we expect another year of profitable growth for our excess and surplus lines insurance segment despite challenging market conditions. Our experienced excess and surplus lines underwriters in the field intend to carefully select and price risks, providing prompt delivery of insurance quotes and policies, as they work with other local field associates who provide outstanding claims and loss control service while also handling standard lines business for their assigned agencies. These local representatives are supported by headquarters underwriters and claims managers who specialize in excess and surplus lines.

 Performance highlights for the life insurance segment include:
 • Revenues – Earned premiums increased 3% for the year 2024, as shown in the table below that includes details by major line of business. Our largest life insurance product line, term life insurance, rose 3%. Net in-force policy face amounts rose 2% to $84.245 billion at year-end 2024 from $82.361 billion at year-end 2023 and $80.482 billion at year-end 2022.
 • Profitability – Our life insurance segment typically reports a smaller profit compared with the life insurance subsidiary because profits from investment income spreads are included in our investments segment results. We include only investment income credited to contract holders (including interest assumed in life insurance policy reserve calculations) in life insurance segment results. A profit of $57 million for our life insurance segment in 2024, compared with $41 million in 2023, was primarily due to more favorable unlocking of interest rate and other actuarial adjustments and more favorable mortality experience. A profit of $41 million in 2023 compared with $27 million in 2022 was primarily due to increased earned premiums and fee revenues along with favorable mortality experience.

 Earned premiums increased $8 million in 2024, primarily due to a $6 million increase in term life insurance earned premiums, as shown in the table below.

 Products we market include term, whole and universal life insurance and also fixed annuities. In addition, we offer term and whole life insurance to employees at their worksite. These products provide our property casualty agency force with excellent cross-serving opportunities for both commercial and personal accounts.

 Over the past several years, we have worked to maintain a portfolio of simple, yet competitive, products. Our product development efforts emphasize death benefit protection and guarantees. Distribution expansion within our property casualty insurance agencies remains a high priority. Our 37 life field marketing representatives work in partnership with our property casualty field marketing representatives. Approximately 60% of our term and other life insurance product premiums were generated through our property casualty insurance agency relationships.

 Life insurance segment expenses consist principally of:
 • Contract holders' benefits incurred, related to traditional life and interest-sensitive products, accounted for 76.4% of 2024 total benefits and expenses (inclusive of investment interest credited to contract holders) compared with 78.4% in 2023 and 78.3% in 2022. Total contract holders' benefits decreased in 2024, compared with 2023, largely due to more favorable impacts from the unlocking of interest rate and other actuarial assumptions. Total
 Cincinnati Financial Corporation - 2024 10-K - Page 81

 contract holder benefits increased slightly in 2023, compared with 2022, largely due to less favorable impacts from the unlocking of interest rate and other actuarial assumptions. Mortality experience was more favorable in 2024, compared with 2023, and net death claims were below our mortality projections.
 • Underwriting expenses incurred, net of deferred acquisition costs, accounted for 23.6% of 2024 total benefits and expenses (inclusive of investment interest credited to contract holders) compared with 21.6% in 2023 and 21.7% in 2022. Expenses in 2024 increased 7%, compared with 3% growth in earned premiums. Expenses in 2023 increased 4%, compared with 4% growth in earned premiums. The 2024 increase in underwriting expenses, compared with the same period a year ago, was largely due to higher general insurance expense levels and increased amortization of deferred policy acquisition costs. The 2023 increase in underwriting expenses was largely due to the same factors that impacted the 2024 increase.

 Life insurance segment profitability depends largely on premium levels, the adequacy of product pricing, underwriting skill and operating efficiencies. This segment's results include only investment interest credited to contract holders (interest assumed in life insurance policy reserve calculations). The remaining investment income is reported in the investments segment results. The life investment portfolio is managed to earn target spreads between earned investment rates on general account assets and rates credited to policyholders. We consider the value of assets under management and investment income for the life investment portfolio as key performance indicators for the life insurance segment. We seek to maintain a competitive advantage with respect to benefits paid and reserve increases by consistently achieving better than average claims experience due to skilled underwriting.

 We recognize that assets under management, capital appreciation and investment income are integral to evaluation of the success of the life insurance segment because of the long duration of life products. On a basis that includes investment income and investment gains or losses from life insurance-related invested assets, our life insurance subsidiary reported net income of $91 million in 2024, compared with $75 million in 2023 and $65 million in 2022. The life insurance subsidiary portfolio had after-tax net investment losses of $6 million in 2024 compared with $7 million in 2023 and $2 million in 2022. Investment gains and losses are discussed under Investments Results. We exclude most of our life insurance company investment income from investments segment results.

 Life Insurance Outlook
 We believe the life insurance market remains attractive. Life insurance ownership remains low compared to historical levels. While people like to research life insurance online, we believe they prefer to speak to a professional agent before making a purchase. Our strong agency relationships and expanding base of agencies gives us a competitive edge in satisfying the life insurance needs that exist for so many Americans.

 Artificial intelligence and improved computing power will continue to allow us to improve our efficiency in writing new business and servicing it. Underwriting in particular will continue to evolve as we work to prudently adopt new, and refine existing models, to evaluate mortality risk without requiring invasive and time intensive traditional medical exams. We believe this improved buying experience will encourage more of our agencies to offer a life insurance product to their property casualty customers.

 Within the life insurance market, we view the voluntary life space as particularly attractive. With our large commercial lines presence, our agencies have tremendous opportunities to serve the employees of these businesses with a simple, voluntary life product. We are enhancing our ability to enroll this business and service it more efficiently, including hiring dedicated associates to augment our agencies' ability to conduct the enrollments. These accounts often lead to business life insurance opportunities that are designed to ensure the viability of the businesses in the event of a death of a key employee or business owner.

 The investments segment contributes investment income and investments gains and losses to results of operations. Investment income is generally our primary source of pretax and after-tax profits.
 • Investment income – Pretax investment income grew $131 million, or 15%, in 2024, due to increases from both interest income and dividends. Interest income grew 22% in 2024, compared with 2023, as net purchases of fixed-maturity securities in recent years and higher average yields for bonds are working to generally offset effects of the low interest rate environment for several years prior to 2022. Dividend income grew less than 1% in 2024, compared with 2023. Dividend rates generally have increased, although more slowly than in prior years. Minor asset allocation adjustments in our equity portfolio, including larger than usual net sales of equity securities during the second half of 2024, unfavorably affected dividend income. Pretax investment income rose 14% in 2023, including increases in interest and dividend income. Average yields in the investment income table below are based on the average invested asset and cash amounts indicated in the table using fixed-maturity securities valued at amortized cost and all other securities at fair value.
 • Investment gains and losses – We reported an investment gain in 2024 and 2023, primarily due to favorable changes in fair values of equity securities even though we continue to hold the securities or as otherwise required by GAAP. We reported an investment loss in 2022, due to unfavorable changes in fair values of equity securities.

 We believe it is useful to analyze our overall investment performance by using total investment return over several years. Total investment return considers changes in unrealized gains and losses that are not included in net income, in addition to net investment income and investment gains and losses that are included in net income. Changes in unrealized gains and losses shown in the table below include other invested assets. Considering total investment gains and losses over several years helps evaluate performance since gains and losses may experience typical variability during shorter periods of time.

 Cincinnati Financial Corporation - 2024 10-K - Page 83

 The table below shows total return based on assumptions that simplify cash flow timing that is commonly used in total return measures. This simplified calculation uses data shown in our consolidated financial statements or notes to those statements. Added to invested asset amounts from our consolidated balance sheets are 50% of annual amounts pertaining to invested asset categories included in net cash used in investing activities from our consolidated statements of cash flows. The cash flow amounts are reduced by net gains from investment portfolio securities sales or called bonds, with the net result reduced by 50% to represent estimated new cash invested during each respective year. All new cash is assumed to be invested at the midpoint of the year.

 Total investment return of 9.3% in 2024 was lower than the 9.9% return in 2023. The 2024 contribution from the investment income component was enhanced by the net favorable effect of the investment gains and losses components. Comparing contributions for 2024 with 2023, investment income rose $131 million, investment gains increased by $264 million and the invested assets net change in unrealized gains and losses decreased by $260 million. The base component of the return calculation, annual average invested assets, was up 13% in 2024. For 2023 compared with 2022, total investment return of 9.9% in 2023 was significantly more than the negative 9.2% return in 2022, as the 2023 contribution from the investment income component was enhanced by the net favorable effect of the investment gains and losses components. The base component of the return calculation, annual average invested assets, decreased 8% in 2023.

 Investment Income
 The primary drivers of investment income are highlighted below, followed by additional details of our investment results.
 • Interest income increased by $133 million, or 22%, in 2024, compared with 2023. The average fixed-maturity pretax yield increased by 28 basis points in addition to a larger fixed-maturity portfolio that rose 15% on an average amortized cost basis. Interest income in 2023 increased by $90 million, compared with 2022, when that yield increased by 34 basis points while the portfolio rose 8% on an amortized cost basis.
 • Dividend income rose $1 million, or less than 1%, in 2024. The increase includes dividend rates that generally have increased, although more slowly than in prior years. Minor asset allocation adjustments in our equity portfolio, including larger than usual net sales of equity securities during the second half of 2024, unfavorably affected dividend income. Dividend income rose $7 million, or 3%, in 2023 reflecting dividend rates that generally increased, minor asset allocations and an increase in funds invested in that portfolio.

 In 2024, we continued to invest available cash flow in both fixed income and equity securities in a manner that we believe balances current income needs with longer-term invested asset growth goals. As bonds in our generally laddered portfolio mature or are called over the near term, we reinvest with a balanced approach, keeping in mind our long-term strategy and pursuing attractive risk-adjusted after-tax yields. While our bond portfolio more than covers our insurance reserve liabilities, we believe our diversified common stock portfolio of mainly blue chip, dividend-paying companies represents one of our best investment opportunities for the long term. We continually perform fundamental analysis of both industry and company-specific opportunities as well as the potential impact from changes in the interest rate environment and the potential for elevated inflation.

 Total Investment Gains and Losses
 Investment gains and losses are recognized on the sales of investments, for certain changes in fair values of securities even though we continue to hold the securities or as otherwise required by GAAP. The change in fair value for equity securities still held is reported in net income, as disclosed in Note 1, Summary of Significant Accounting Policies. Total investment gains and losses in 2024 included $1.275 billion of net gains from the recognition of fair value changes of equity securities still held that prior to 2018 would have been reported in other comprehensive income (OCI) instead of net income. Change in unrealized gains or losses for fixed-maturity securities are included as a component of OCI. Accounting requirements for the allowance for credit losses and impairment charges for write-downs of impaired securities in the fixed-maturity portfolio are disclosed in Item 8, Note 1, Summary of Significant Accounting Policies. The factors we consider when evaluating impairments are also discussed in Critical Accounting Estimates, Asset Impairment.

 The timing of gains or losses from sales can have a material effect on results in any given period. However, such gains or losses usually have little, if any, effect on total shareholders' equity because most equity and fixed-maturity investments are carried at fair value.

 As appropriate, we buy, hold or sell both fixed-maturity and equity securities on an ongoing basis to help achieve our portfolio objectives. We generally purchase fixed-maturity securities with the intention to hold until maturity. If they no longer meet our investment criteria, they are divested. Sales of fixed-maturity securities are usually due to a change in credit fundamentals. Pretax total investment gains in 2024 and 2023 were largely due to favorable changes in fair values of equity securities, even though we continue to hold the securities, as shown in the table below. In 2022, the pretax total investment loss was due to unfavorable changes in fair values of equity securities and a net unfavorable change in unrealized gains or losses for fixed-maturity securities. Additional information about investment gains or losses is included in Item 8, Note 2 of the Consolidated Financial Statements.

 The table below summarizes total investment gains and losses, before taxes.

 Investments Outlook
 Federal Reserve inaction due to inconsistent inflation data points led to volatile interest rate levels over the course of 2024. With data seeming to indicate inflation was under control, the Federal Reserve pivoted and began its rate cutting program in late September.

 With yields at highs not seen in years, we focused our purchase activity on fixed-maturity securities and diverted new money away from equity securities as the S&P 500 Index return in 2024 exceeded 20% for the second consecutive year. We benefited from our ongoing equity exposure but repositioned the portfolio to take advantage of the strength in stocks and the yields in the bond market.

 Our investment portfolio is well-positioned to pursue market opportunities that present themselves in 2025. If yields remain high, we are ready to continue emphasizing bond purchases. If the stock market retrenches, we are prepared to take advantage of value opportunities, maintaining our longer-term approach of seeking both growth of investment income and portfolio appreciation. We discuss our portfolio strategies in Item 1, Our Segments, Investments Segment.

 Cincinnati Financial Corporation - 2024 10-K - Page 89

 Other
 Total revenues in 2024 and 2023 for our Other operations increased, compared with the respective prior-year periods, primarily due to higher earned premiums from Cincinnati Re and Cincinnati Global in total. Other also includes noninvestment operations of the parent company and its commercial leasing and financial services subsidiary, CFC Investment Company. Total expenses for Other increased in 2024 but decreased in 2023, with the change for both years primarily due to losses and loss expenses and underwriting expenses from Cincinnati Re and Cincinnati Global.

 Other income or loss in the table below represents profit or losses before income taxes. For 2024 and 2023, Other income was driven by underwriting profit for Cincinnati Re and Cincinnati Global. For 2022, Other loss was largely driven by interest expense from debt of the parent company. Net results for the combination of Cincinnati Re and Cincinnati Global were an underwriting profit of $158 million in 2024, $183 million in 2023 and $36 million in 2022.

 Cincinnati Re represented 68% of Other earned premiums in 2024 and 54% of underwriting profit. Earned premiums in 2024, compared with 2023, grew 8%. The mix of 2024 earned premiums for Cincinnati Re by primary type of insured exposures included 43% for casualty, 40% for property and 17% for specialty. Cincinnati Re in total generated an underwriting profit of $86 million in 2024, $118 million in 2023 and $13 million in 2022.

 Cincinnati Global represented 32% of Other earned premiums in 2024 and 46% of underwriting profit. In 2024, earned premiums rose 2%, compared with 2023. Underwriting profit for Cincinnati Global was $72 million in 2024, $65 million in 2023 and $23 million in 2022.

 Taxes
 We had a $566 million income tax expense in 2024, compared with $433 million in 2023 and an income tax benefit of $207 million in 2022. The corporate effective tax rate for 2024 was 19.8% compared with 19.0% in 2023 and 29.8% in 2022.

 The changes in our effective tax rate between periods were primarily due to large changes in our net investment gains and losses included in income for the periods, and changes in underwriting income and investment income.

 Our effective tax rate includes impacts from Cincinnati Global's operations in the United Kingdom. The United Kingdom is one of several global jurisdictions that have enacted laws consistent with The Organisation for Economic Co-operation and Development (OECD) "Pillar Two" model rules aimed at imposing a global minimum tax rate of 15 percent. The UK's Pillar Two laws, generally effective as of January 1, 2024, did not have a material impact on our effective tax rate in 2024.

 Historically, we have pursued a strategy of investing some portion of cash flow in tax-advantaged, fixed-maturity securities and some in equity securities to minimize our overall tax liability and maximize after-tax earnings. See Item 1, Our Segments, Fixed-Maturity Securities Investments, for further discussion on municipal bond purchases in our fixed-maturity investment portfolio.

 For tax years after 2017, for our property casualty insurance subsidiaries, approximately 75% of interest from tax-advantaged, fixed-maturity investments and approximately 40% of dividends from qualified equities are exempt from federal tax after applying proration. For our noninsurance companies, the dividend received deduction exempts 50% of dividends from qualified equities. Our life insurance company does not own tax-advantaged, fixed-maturity investments or equities subject to the dividend received deduction.

 Our effective tax rate reconciliation is found in Item 8, Note 11 of the Consolidated Financial Statements.

 Cincinnati Financial Corporation - 2024 10-K - Page 91

 Liquidity and Capital Resources
 We seek to maintain prudent levels of liquidity and financial strength for the protection of our policyholders, creditors and shareholders. We manage liquidity at two levels to meet the short- and long-term cash requirements of business obligations and growth needs. The first is the liquidity of the parent company. The second is the liquidity of our lead insurance subsidiary. Management of liquidity at both levels is essential because each has different funding needs and sources, and each is subject to certain regulatory guidelines and requirements.

 In addition to our historically positive operating cash flow to meet the needs of operations, we have the ability to slow investing activities if such need arises or to sell a portion of our high-quality, liquid investment portfolio. We also have additional capacity to borrow on our revolving short-term line of credit, as described further below.

 Parent Company Liquidity
 At December 31, 2024, the parent company had $5.203 billion in cash and marketable securities, providing strong liquidity to fund cash outflows, as needed. The parent company's primary sources of cash inflows are dividends from our lead insurance subsidiary, investment income and sale proceeds from investments. The parent company's cash outflows are primarily interest and principal payments on long- and short-term debt, dividends to shareholders, common stock repurchases, and general operating expenses. To support our shareholders' dividend payment, we could use subsidiary dividends, our line of credit or sell a portion of our marketable securities.

 The table below shows a summary, by the direct cash flow method, of the major sources and uses of cash flow of the parent company.

 Share repurchases

 Debt interest payments

 Use of liquidity for share repurchases are discretionary depending on cash availability and capital management decisions. In addition, the subsidiaries have the discretion to pay dividends to the parent company. Cincinnati Global is required to maintain certain capital funding requirements with Lloyd's, which the parent company may deposit on its behalf. These funding requirements may fluctuate based on the profitability of Cincinnati Global and syndicate solvency capital requirements as set by Lloyd's, which may result in additional contributions to or return of funds on deposit. Other than share repurchases and funding at Lloyd's, the majority of expenditures for the parent company have been consistent during the last three years, and we expect future expenditures to remain stable.

 Cincinnati Financial Corporation - 2024 10-K - Page 92

 Insurance Subsidiary Liquidity
 The parent company's lead insurance subsidiary largely represents the operations of the property casualty segments. The primary sources of cash inflows are collection of premiums, investment income, maturity of fixed-income securities and sale proceeds from investments. Property casualty insurance premiums generally are received before losses are paid under the policies purchased with those premiums. Cash outflows are primarily loss and loss expenses, commissions, salaries, taxes, operating expenses and investment purchases. Over the three-year period ended December 31, 2024, premium receipts and investment income have been more than sufficient to pay claims and operating expenses. Excess cash flows were partially used to pay dividends to the parent company. We are not aware of any known trends that would materially change historical cash flow results, other than fluctuations in catastrophe claims and other large losses, either individually or in aggregate.

 The table below shows a summary of operating cash flow for property casualty insurance (direct method). Historically, annual variation in operating cash flow has been largely related to changes in amounts of catastrophe losses.

 Other Sources of Liquidity
 Cash in excess of operating requirements is invested in fixed-maturity and equity securities. Cash generated from investment income provides an important investment contribution to cash flow and liquidity. The sale of investments could provide an additional source of liquidity at either the parent company or insurance subsidiary level, if required. In addition to possible sales of investments, proceeds of calls or maturities of fixed-maturity securities also can provide liquidity. During the five-year period beginning in 2025, fair value of $5.244 billion, or 31.8%, of our fixed-maturity and short-term portfolio is scheduled to mature. At December 31, 2024, we had $10.836 billion of common stock securities, with $ 4.563 billion, or 42%, held by the parent company.

 Financial resources of the parent company also could be made available to our insurance subsidiaries, if circumstances required it. This flexibility would include our ability to access the capital markets and short-term bank borrowings. We generally have minimized our reliance on debt financing, although we may use the line of credit to fund short-term cash needs.

 Cincinnati Financial Corporation - 2024 10-K - Page 93

 Long-Term Debt
 We provide details of our three long-term notes in Item 8, Note 8 of the Consolidated Financial Statements. None of the notes are encumbered by rating triggers. The total principal amount of our long-term debt at December 31, 2024, was $793 million and included:
 •$28 million aggregate principal amount of 6.900% senior debentures due 2028.
 •$391 million aggregate principal amount of 6.920% senior debentures due 2028.
 •$374 million aggregate principal amount of 6.125% senior debentures due 2034.

 The company's senior debt is rated investment grade by four independent rating agencies. None of the rating agencies made changes to our debt ratings in 2024. At February 21, 2025, our debt ratings from the rating agencies were: a from A.M. Best, A- from Fitch, A3 from Moody's and BBB+ from S&P.

 Note Payable
 At December 31, 2024, we had a $300 million line of credit with commercial banks, with $25 million borrowed at both December 31, 2024 and 2023. That unsecured revolving line of credit has an accordion feature giving us the option to double the $300 million amount, under the same terms and conditions. Terms and conditions of the agreement include a debt-to-total capital maximum of 35% and the agreement has no net worth covenant. It was due to expire on February 4, 2024, with the option of two one-year extensions. We exercised both one-year options to extend the term of the line of credit by two additional years to February 4, 2026.

 At year-end 2024, we were in compliance with all covenants under the credit agreement and believe we will remain in compliance. The credit agreement provides alternative interest charges based on the type of borrowing and our debt rating. On March 23, 2023, we amended our line of credit agreement to replace LIBOR with the Secured Overnight Financing Rate (SOFR) plus a credit spread adjustment.

 Capital Resources
 Capital resources, consisting of shareholders' equity and total debt, represent our overall financial strength to support current obligations and growth in our insurance businesses. At December 31, 2024, we had total capital of $14.750 billion. Shareholders' equity was $13.935 billion, an increase of $1.837 billion, or 15%, from the prior year. Our total debt was $815 million, unchanged from a year ago. We seek to maintain a solid financial position and provide capital flexibility by keeping our ratio of debt to total capital moderate. At year-end 2024, the ratio was 5.5%, compared with 6.3% at year-end 2023.

 At times we enter into letter of credit agreements to support our Cincinnati Re and Cincinnati Global operations. On December 23, 2024, we entered into a reimbursement agreement to allow for issuances of letters of credit necessary for the operations of Cincinnati Re, not to exceed $25 million. No amounts were drawn at December 31, 2024. We had an unsecured letter of credit agreement of $94 million to provide a portion of the capital needed to support Cincinnati Global's obligations at Lloyd's, with no amounts drawn at December 31, 2023. On September 12, 2024, we terminated our unsecured letter of credit agreement and replaced the letter of credit agreement with common equities, bringing total common equities held in Lloyd's trust accounts to $216 million, at December 31, 2024.

 At the discretion of the board of directors, the company can return capital directly to shareholders as discussed below.
 • Dividends to shareholders – The ability of our company to continue paying cash dividends is subject to factors the board of directors deems relevant. While the board and management believe there is merit to sustaining the company's long record of dividend increases, our first priority is the company's financial strength. Over the past 10 years, the company has paid an average of 29% of net income as dividends. Through 2024, the board had increased our cash dividend for 64 consecutive years. The board's decision in January 2025 to increase the dividend demonstrated confidence in the company's strong capital, liquidity, financial flexibility and initiatives to grow earnings.
 • Common stock repurchase – Generally, our board believes that share repurchases can help fulfill our commitment to enhancing shareholder value. Consequently, the board has authorized the repurchase of outstanding shares, giving management discretion to purchase shares at reasonable prices in light of circumstances at the time of purchase. Our approach has been to hold capital adequate to support future growth of our insurance operations and repurchase shares at management's discretion. Repurchases are intended to offset the issuance of shares
 Cincinnati Financial Corporation - 2024 10-K - Page 94

 through equity compensation plans, primarily due to vesting of service-based restricted stock units of equity awards granted in the past. The amount of future repurchases may be more, or less, than the past, depending on circumstances and discretion exercised by management. Our corporate Code of Conduct restricts repurchases during certain time periods. The details of the repurchase authorizations and activity are described in Item 5, Market for the Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

 Obligations
 We pay obligations to customers, suppliers and associates in the normal course of our business operations. Some are contractual obligations that define the amount, circumstances and/or timing of payments. We have other commitments for business expenditures; such as $188 million we expect to fund for our private equity and real estate investments, however, the amount, circumstances and/or timing of our other commitments are not dictated by contractual arrangements.

 Liquidity and Capital Resources Outlook
 At December 31, 2024, we had $983 million in cash and cash equivalents. During 2025, our lead insurance subsidiary may pay a maximum of $1.245 billion in dividends to our parent company without regulatory approval. That strong liquidity and our consistent cash flows give us the flexibility to meet current obligations and commitments while building value by prudently investing where we see potential for both current income and long-term return. Our cash and cash equivalents provide adequate financial cushion when short-term operating results do not meet our objectives.

 A long-term perspective governs our liquidity and capital resources decisions, with the goal of benefiting our policyholders, agents, shareholders and associates over time. Our underwriting philosophy and initiatives can drive performance to achieve underwriting profit. Our GAAP combined ratio averaged 94.6% over the five-year period 2020 through 2024, resulting in strong underwriting profits.

 In any year, we consider the most likely source of pressure on liquidity would be an unusually high level of catastrophe loss payments within a short period of time. There could be additional obligations for our insurance operations due to increasing severity or frequency of noncatastrophe claims. To address the risk of unusually large insurance loss obligations, including catastrophe events, we maintain property casualty reinsurance contracts with highly rated reinsurers, as discussed under 2025 Reinsurance Ceded Programs. We also monitor the financial condition of our reinsurers because their insolvency could jeopardize a portion of our $523 million reinsurance recoverable asset at December 31, 2024. Parent-company liquidity could also be constrained by Ohio regulatory requirements that restrict the dividends insurance subsidiaries can pay.

 Economic weakness also has the potential to affect our liquidity and capital resources in a number of different ways, including delinquent payments from agencies, defaults on interest payments by fixed-maturity holdings in our portfolio, dividend reductions by holdings in our equity portfolio or declines in the market value of holdings in our portfolio.

 Cincinnati Financial Corporation - 2024 10-K - Page 95

 Off-Balance-Sheet Arrangements
 We do not use any special-purpose financing vehicles or have any undisclosed off-balance-sheet arrangements (as that term is defined in applicable SEC rules) that are reasonably likely to have a current or future material effect on the company's financial condition, results of operation, liquidity, capital expenditures or capital resources.

 Property Casualty Loss and Loss Expense Obligations and Reserves
 Our estimate of future gross property casualty loss and loss expense payments of $9.937 billion is lower than loss and loss expense reserves of $10.003 billion reported on our balance sheet at December 31, 2024. The $66 million difference is due to certain life and health loss reserves. Reserving practices are discussed in Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves.

 For the business lines in the commercial and personal lines insurance segments, and in total for the excess and surplus lines insurance segment and for other parts of our property casualty insurance operations, the following table details gross reserves among case, IBNR and loss expense reserves, net of salvage and subrogation. The $962 million increase in total gross reserves included an $8 million decrease in case loss reserves, a $788 million increase in IBNR loss reserves and a $182 million increase in loss expense reserves. The increase in total gross reserves included $335 million for our commercial casualty line of business, $177 million for excess and surplus lines and $168 million for Cincinnati Re.

 Asbestos and Environmental Loss and Loss Expense Reserves
 We carried $119 million of net loss and loss expense reserves for asbestos and environmental claims at year-end 2024, compared with $98 million at year-end 2023. The asbestos and environmental claims amounts for each respective year constituted less than 2.0% of total net loss and loss expense reserves at these year-end dates.

 We believe our exposure to asbestos and environmental claims is limited, largely because our reinsurance retention was $500,000 or below prior to 1987. We also were predominantly a personal lines company in the 1960s and 1970s, when asbestos and pollution exclusions were not widely used by commercial lines insurers. During the 1980s and early 1990s, commercial lines grew as a percentage of our overall business and our exposure to asbestos and environmental claims grew accordingly. Over that period, we endorsed to or included in most policies an asbestos and environmental exclusion.

 Additionally, since 2002, we have revised policy terms where permitted by state regulation to limit our exposure to mold claims prospectively and further reduce our exposure to environmental claims generally. Finally, we have not engaged in any mergers or acquisitions through which such a liability could have been assumed. We continue to monitor our claims for evidence of material exposure to other mass tort classes, but we have found no such credible evidence to date.

 Reserving data for asbestos and environmental claims has characteristics that limit the usefulness of the methods and models used to analyze loss and loss expense reserves for other claims. Specifically, asbestos and environmental loss and loss expenses for different accident years do not emerge independently of one another as loss development and Bornhuetter-Ferguson methods assume. In addition, asbestos and environmental loss and loss expense data available to date did not reflect a well-defined tail, greatly complicating the identification of an appropriate probabilistic trend family model. At year-end 2024, we used a weighted average of a paid survival ratio method and report year method to estimate reserves for IBNR asbestos and environmental claims. Our exposure to such claims is limited; we believe a weighted average of both methods produces a sufficient level of reserves.

 Gross Property Casualty Loss and Loss Expense Payments
 While we believe that historical performance of property casualty and life loss payment patterns is a reasonable source for projecting future claim payments, there is inherent uncertainty in this estimate of contractual obligations. We believe that we could meet our obligations under a significant and unexpected change in the timing of these payments because of the liquidity of our invested assets, strong financial position and access to lines of credit.

 Our estimates of gross property casualty loss and loss expense payments do not include reinsurance receivables or ceded losses. As discussed in 2025 Reinsurance Ceded Programs, we purchase reinsurance to mitigate our property casualty risk exposure. Ceded property casualty reinsurance unpaid receivables of $269 million at year-end 2024 are an offset to our gross property casualty loss and loss expense obligations. Our reinsurance program mitigates the liquidity risk of a single large loss or an unexpected rise in claim severity or frequency due to a catastrophic event. Reinsurance does not relieve us of our obligation to pay covered claims. The financial strength of our reinsurers is important because our ability to recover losses under our reinsurance agreements depends on the financial viability of the reinsurers.

 We direct our associates to settle claims and pay losses as quickly as is practical, and we made $4.381 billion of net claim payments during 2024. At year-end 2024, total net property casualty reserves of $9.668 billion reflected $3.499 billion in unpaid amounts on reported claims (case reserves), $1.785 billion in loss expense reserves and $4.384 billion in estimates of claims that were incurred but had not yet been reported (IBNR). The specific amounts and timing of obligations related to case reserves and associated loss expenses are not set contractually. The amounts and timing of obligations for IBNR claims and related loss expenses are unknown. We discuss our methods of establishing loss and loss expense reserves and our belief that reserves are adequate in Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves.

 Cincinnati Financial Corporation - 2024 10-K - Page 98

 The historical pattern of using premium receipts for the payment of loss and loss expenses has enabled us to extend slightly the maturities of our investment portfolio beyond the estimated settlement date of the loss reserves. The effective duration of our consolidated property casualty fixed-maturity portfolio was 5.2 years at year-end 2024. By contrast, the duration of our loss and loss expense reserves was approximately 3.3 years. We believe this difference in duration does not affect our ability to meet current obligations because cash flow from operations is sufficient to meet these obligations. In addition, investment holdings could be sold, if necessary, to meet higher than anticipated loss and loss expenses.

 Range of Reasonable Reserves
 The company established a reasonably likely range for net loss and loss expense reserves of $8.948 billion to $9.816 billion at year-end 2024, with the company carrying net reserves of $9.668 billion. The range was $7.926 billion to $8.704 billion at year-end 2023, with the company carrying net reserves of $8.613 billion. Our loss and loss expense reserves are not discounted for the time-value of money, but we have reduced the reserves by an estimate of the amount of salvage and subrogation payments we expect to recover.

 The low point of each year's range corresponds to approximately one standard error below each year's mean reserve estimate, while the high point corresponds to approximately one standard error above each year's mean reserve estimate. We discussed management's reasons for basing reasonably likely reserve ranges on standard errors in Critical Accounting Estimates, Reserve Estimate Variability.

 The ranges reflect our assessment of the most likely unpaid loss and loss expenses at year-end 2024 and 2023. However, actual unpaid loss and loss expenses could nonetheless fall outside of the indicated ranges.

 Management's best estimate of total loss and loss expense reserves as of year-end 2024 and 2023 was consistent with the corresponding actuarial best estimate.

 Overall favorable development for consolidated property casualty reserves of $236 million in 2024 illustrated the potential for revisions inherent in estimating reserves, especially for long-tail lines such as commercial casualty and workers' compensation. As noted in Critical Accounting Estimates, Key Assumptions Loss Reserving, our models predict that actual loss and loss expense emergence will differ from projections, and we do not attempt to monitor or identify such normal variations. The table in Property Casualty Loss and Loss Expense Obligations and Reserves shows reserves by segment and lines of business and the components of gross reserves among case, IBNR and loss expense reserves.

 Cincinnati Financial Corporation - 2024 10-K - Page 100

 Favorable reserve development was $83 million for our workers' compensation line of business, $74 million for our commercial property line of business and $54 million for our homeowner line of business, together accounting for approximately 89% of the overall total. Unfavorable, or adverse, reserve development included $26 million for our commercial casualty line of business. Drivers of significant reserve development typically reflect loss emergence on known claims that was more favorable or less favorable than previously anticipated for various lines of business and are discussed below.
 • Commercial casualty – During 2024 and 2023, we experienced unfavorable development on prior accident years in aggregate, driven by general liability coverages. Loss emergence for general liability claims rose more than anticipated and reflected economic or other forms of inflation. Due to increased uncertainty regarding ultimate losses, we intend to remain prudent in reserving for estimated ultimate losses until longer-term loss cost trends become more clear. We continue to monitor activity for various commercial casualty coverages so we can detect changes in trends on a timely basis.
 • Workers' compensation – We experienced favorable reserve development again during 2024, for all prior accident years in aggregate, as claim frequencies continued to decline more than we expected. However, we continue to monitor this line of business closely, as a sudden increase in trend for future payments has a highly leveraged effect.
 • Commercial auto – Ultimate losses developed favorably by small amounts during calendar years 2024 and 2023, for all prior accident years in aggregate. We believe inflation in recent years and reduced driving during the pandemic caused deviations from historical loss patterns. Due to increased uncertainty regarding ultimate losses, we intend to remain prudent in reserving for estimated ultimate losses until longer-term loss cost trends become more clear.
 • Commercial property and homeowner – Loss emergence was less than anticipated for both 2024 and 2023. The majority of homeowner favorable reserve development for both years related to natural catastrophe events with inherently variable loss patterns. For commercial property, catastrophe events accounted for a significant portion, but less than half, of the favorable reserve development for both years.

 For the excess and surplus lines insurance segment, the table showing reserves by segment and lines of business in Property Casualty Loss and Loss Expense Obligations and Reserves, shows the components of gross reserves among case, IBNR and loss expense reserves. Total gross reserves increased $177 million from year-end 2023, largely due to the increase in premiums and exposures for this segment, as we discussed in Excess and Surplus Lines Insurance Results. Net reserve development was an unfavorable $8 million during 2024, following favorable development of $11 million during 2023 and $9 million during 2022. Approximately 90% of our excess and surplus lines insurance premiums are for commercial casualty coverages. In 2024, loss emergence for claims rose more than anticipated and reflected economic or other forms of inflation, similar to our commercial casualty line of business. Unfavorable reserve development following a period of favorable development, or vice-versa, shown in the table above, illustrates the potential for revisions inherent in estimating reserves.

 Cincinnati Financial Corporation - 2024 10-K - Page 101

 Life Insurance Policyholder Obligations and Reserves

 Gross Life Insurance Policyholder Obligations
 Our estimates of life, annuity and disability policyholder obligations reflect future estimated cash payments to be made to policyholders for future policy benefits, policyholders' account balances and separate account liabilities. These estimates include death and disability income claims, policy surrenders, policy maturities, annuity payments, minimum guarantees on separate account products, commissions and premium taxes offset by expected future deposits and premiums on in-force contracts. Further, these estimates are based on mortality, morbidity and lapse assumptions reflective of our recent experience and expectations of future payment obligations.

 Our estimates of gross life, annuity and disability obligations do not reflect net recoveries from reinsurance agreements. Ceded life reinsurance receivables were $207 million at year-end 2024. As discussed in 2025 Reinsurance Ceded Programs, we purchase reinsurance to mitigate our life insurance risk exposure. At year-end 2024, ceded death benefits represented approximately 32% of our total gross policy face amounts in force.

 These estimated cash outflows are undiscounted with respect to interest. As a result, the sum of the cash outflows for all years of $5.971 billion (total of life insurance obligations) exceeds the liabilities recorded in life policy and investment contract reserves and separate accounts for future policy benefits and claims of $3.909 billion (total of life insurance policy reserves and separate account policy reserves). A significant portion of the difference can be attributed to the time value of money.

 We have made significant assumptions to determine the estimated undiscounted cash flows of these policies and contracts that include mortality, morbidity, future lapse rates and interest crediting rates. Due to the significance of the assumptions used, the amounts presented could materially differ from actual results.

 Life Insurance Reserves
 Gross life policy and investment contract reserves were $2.960 billion at year-end 2024, compared with $3.068 billion at year-end 2023. The decrease was primarily due to an increase in market value discount rates partially offset by continued growth in net in-force life insurance policy face amounts. We establish reserves for traditional life insurance policies based on certain cash flow assumptions including mortality, morbidity and lapse rates as well as a discount rate assumption. The cash flow assumptions are based on our current expectations and are reviewed annually to determine any necessary updates. These assumptions are also updated on an interim basis if evidence suggests that they should be revised. The discount rate assumption is based on upper-medium grade fixed-income instrument yields (market value discount rates) and is updated quarterly. We use both our own experience and industry experience adjusted for historical trends in arriving at our cash flow assumptions.

 We establish reserves for our universal life, deferred annuity and other investment contracts equal to the cumulative account balances, which include premium deposits plus credited interest less charges and withdrawals. Some of our universal life insurance policies contain no-lapse guarantee provisions. For these policies, we establish a reserve in addition to the account balance based on expected no-lapse guarantee benefits and expected policy assessments.

 Modeled Catastrophe Loss Exposure
 A single large loss or an unexpected rise in claims severity or frequency due to a catastrophic event is a risk to the company's liquidity and financial strength. To control such losses, we limit marketing property casualty insurance in specific geographic areas and monitor our exposure in certain coastal regions. Examples of this include limiting our earthquake writings in the New Madrid region or leveraging more restrictive terms and conditions through the use of our excess and surplus company in higher risk areas for wildfire or hurricane. Loss exposures in these areas have been identified as a major contributor to our catastrophe probable maximum loss estimates. We also continually review aggregate exposures to large disasters and purchase reinsurance protection to cover these exposures. For business other than Cincinnati Re and Cincinnati Global, we use the Risk Management Solutions (RMS) and Verisk models to evaluate exposures to a once-in-a-100-year and a once-in-a-250-year event to help determine appropriate reinsurance coverage programs. In conjunction with these activities, we also continue to evaluate information provided by our reinsurance broker. Examples include deterministic modeling of probable maximum loss contribution from growth in new geographic territories.

 To help determine appropriate reinsurance coverage for hurricane, earthquake and severe convective storm exposures, for business other than Cincinnati Re and Cincinnati Global we use the RMS and Verisk models to estimate the probable maximum loss from a single event or multiple events occurring in a one-year period. The models are proprietary in nature, and the vendors that provide them periodically update the models, sometimes resulting in significant changes to their estimate of probable maximum loss. As of the end of 2024, both models indicated that a hurricane event represents our largest amount of exposure to losses. The table below summarizes estimated probabilities and the corresponding probable maximum loss from a single hurricane event occurring in a one-year period and indicates the effect of such losses on consolidated shareholders' equity at December 31, 2024. Net losses are net of reinsurance, estimated reinstatement premiums and income taxes, assuming a 21% federal tax rate, and assume our 2025 reinsurance programs apply.

According to these models, probable maximum loss estimates from a single hurricane event that combine the effects of property casualty insurance written on a direct basis by The Cincinnati Insurance Companies, the Cincinnati Re reinsurance portfolio and risks insured by Cincinnati Global include the following amounts, net of amounts recoverable through reinsurance ceded and also income taxes, and including the effects of estimated reinstatement premiums: $625 million for a once-in-a-100-year event and $949 million for a once-in-a-250-year event.

 The modeled losses according to RMS in the table are based on its RiskLink version 24 catastrophe model and use a long-term storm catalog methodology. The modeled losses according to Verisk in the table are based on its Touchstone version 10.0 catastrophe model and use a long-term methodology. The Verisk and RMS storm catalogs include decades of documented weather events used in simulations for probable maximum loss projections.

 Based on treaties in effect at January 1, 2025, the largest loss exposure to us for Cincinnati Re is from natural catastrophe events. That exposure includes probable maximum loss estimates of the following amounts: $242 million for a once-in-a-100-year event and $321 million for a once-in-a-250-year event. Those effects are on a standalone basis and represent a single hurricane event and include the effects of income taxes, estimated reinstatement premiums and applicable reinsurance ceded, including any retrocessions for reinsurance assumed, and estimated reinstatement premiums. They are based on probable maximum loss estimates from the Verisk Touchstone version 10.0 catastrophe model.

 2025 Reinsurance Ceded Programs
 Reinsurance mitigates the risk of highly uncertain exposures and limits the maximum net loss that can arise from large risks or risks concentrated in areas of exposure. Management's decisions about the appropriate structure of reinsurance protection and level of risk retention are affected by various factors, including changes in our underwriting practices, capacity to retain risks and reinsurance market conditions.

 Reinsurance does not relieve us of our obligation to pay covered claims. The financial strength of our reinsurers is important because our ability to recover for losses covered under any reinsurance agreement depends on the financial viability of the reinsurer.

 For 2025, the primary participants on our standard market property and casualty per-risk and per-occurrence reinsurance ceded programs include Hannover Ruck SE, Munich Reinsurance America, Partner Reinsurance Company of the U.S., Transatlantic Reinsurance Company and Swiss Reinsurance America Corporation, all of which had A.M. Best insurer financial strength ratings of A (Excellent) or better as of December 31, 2024. Our property catastrophe program is subscribed through a broker by reinsurers from the U.S., Bermuda, London and the European markets. The largest participant in our property catastrophe program, representing approximately 16% of total participation, is the Lloyd's of London placement that features numerous syndicates. Some of the other reinsurers with large participation in the program include Partner Reinsurance Company Ltd., Mapfre Re, Lancashire Insurance Company Limited, Chubb Tempest Reinsurance Ltd. and Hamilton Re, Ltd.

 The following table shows our five largest property casualty reinsurance receivable amounts by reinsurer at year-end 2024 and 2023. Michigan Catastrophic Claims Association is a mandatory nonprofit association which runs a reinsurance program funded by an annual premium assessment per vehicle. This assessment covers Michigan's automobile no-fault policies, which provide unlimited lifetime coverage for medical expenses resulting from auto accidents. The A.M. Best insurer financial strength ratings as of the end of the two most recent years are also shown for each of those reinsurers that have an applicable rating.

 Primary components of the 2025 property and casualty reinsurance program are summarized below. The premium estimates below occurred near the beginning of each respective year, when direct written premiums that were subject to applicable reinsurance treaties were also estimated.
 • Property per risk treaty – The primary purpose of the property treaty is to provide capacity up to $50 million, adequate for the majority of the risks we write. It also includes protection for extra-contractual liability coverage losses. We retain the first $15 million of each loss. Losses between $15 million and $50 million are reinsured at 100%. The 2025 ceded premium estimate was $52 million, compared with $71 million for the 2024 estimate when we retained the first $10 million of each loss.
 • Property excess treaty – We purchased a property reinsurance treaty that provides an additional $75 million in protection for certain property losses. This treaty, along with the property per risk treaty, provides a total of $125 million of protection. The 2025 ceded premium estimate was approximately $14 million, compared with $9 million for the 2024 estimate when the coverage amount was $50 million.
 • Casualty per occurrence treaty – The casualty treaty provides capacity up to $25 million. Similar to the property treaty, it provides sufficient capacity to cover the vast majority of casualty accounts we insure and also includes protection for extra-contractual liability coverage losses. We retain the first $10 million of each loss. Losses between $10 million and $25 million are reinsured at 100%. The 2025 ceded premium estimate was $21 million, compared with $20 million for the 2024 estimate.
 • Casualty excess treaty – We purchase a casualty reinsurance treaty that provides an additional $55 million in protection for certain casualty losses. This treaty, along with the casualty per occurrence treaty, provides a total of
 Cincinnati Financial Corporation - 2024 10-K - Page 105

 $80 million of protection for workers' compensation, extra-contractual liability coverage and clash coverage losses, which would apply when a single occurrence involves multiple policyholders of The Cincinnati Insurance Companies or multiple coverages for one insured. The 2025 ceded premium estimate was approximately $5 million, compared with $4 million for the 2024 estimate when the coverage was $70 million.
 • Property catastrophe treaty – To protect against catastrophic events such as wind and hail, wildfires, winter storms, hurricanes or earthquakes, we purchased property catastrophe reinsurance with a limit up to $1.500 billion. This treaty and our property and casualty treaties contain exclusions for communicable disease and cyber losses. Aggregation of losses into one event, sometimes referred to as an hours clause, varies by peril. For example, the general provision in this treaty is 168 hours, but it is 120 hours for a wind event and 96 hours for a riot or civil commotion event. Losses from the same occurrence can be aggregated into one limit over the hour period applicable to the peril causing the loss and applied to the treaty towards recovery. The treaty contains one reinstatement provision. The 2025 ceded premium estimate was $98 million, compared with $76 million for the 2024 estimate when the limit of coverage was $1.200 billion and we retained more risk for some of the layers described below. We retain the first $200 million of any loss, and a share of losses up to $1.500 billion. The percentage share we retain for each layer of coverage is indicated below:
 56.3% of losses between $200 million and $300 million
 25.0% of losses between $300 million and $400 million
 12.5% of losses between $400 million and $600 million
 12.5% of losses between $600 million and $800 million
 12.5% of losses between $800 million and $1.000 billion
 15.0% of losses between $1.000 billion and $1.300 billion
 15.0% of losses between $1.300 billion and $1.450 billion
 15.0% of losses between $1.450 billion and $1.500 billion
 After reinsurance our maximum exposure to a catastrophic event that causes $1.500 billion in covered losses in 2025 would be $431 million, compared with retention of $748 million in 2024 for an event causing $1.500 billion in covered losses. The largest catastrophe loss event in our history prior to 2025 occurred during 2022 from a December 21-31 winter storm system that affected many states in the U.S. Our losses from that storm were estimated to be $247 million, before reinsurance, as of December 31, 2024. The second largest catastrophe loss event in our history occurred during 2011 from a May 20-27 storm system that included a tornado in Joplin, Missouri, and that also included significant losses from hail in the Dayton, Ohio, area. Our losses from that storm were estimated to be $226 million, before reinsurance, based on updated estimates as of December 31, 2017.

 Individual risks with insured values in excess of $125 million, as identified in the policy, are handled through a different reinsurance mechanism. We typically reinsure commercial property coverage for individual risks with insured values between $125 million and $360 million under an automatic facultative agreement. For commercial property risks with property values exceeding $360 million, we negotiate the purchase of facultative coverage on an individual certificate basis. For casualty coverage on individual risks with limits exceeding $25 million, facultative reinsurance coverage is placed on an individual certificate basis. For risks with casualty limits that are between $25 million and $27 million, we sometimes forego facultative reinsurance and retain an additional $2 million of loss exposure.

 Terrorism coverage at various levels has been secured in most of our reinsurance agreements. The broadest coverage for this peril is found in the property and casualty working treaties, the property per risk treaty and the casualty per occurrence treaty, which provide coverage for commercial and personal risks. Our property catastrophe treaty provides terrorism coverage for personal risks and commercial risks. For insured values between $15 million and $125 million, there also may be coverage in the property working treaty.

 A form of reinsurance is also provided through The Terrorism Risk Insurance Act of 2002 (TRIA). TRIA was originally signed into law on November 26, 2002, and extended on several occasions. The most recent extension was signed into law on December 20, 2019, and is scheduled to expire on December 31, 2027. TRIA provides a temporary federal backstop for losses related to the writing of the terrorism peril in property casualty insurance policies. Under regulations promulgated under this statute, insurers are required to offer terrorism coverage for certain lines of property casualty insurance, including property, commercial multi-peril, fire, ocean marine, inland marine, liability, aircraft and workers' compensation. In the event of a terrorism event defined by TRIA, the federal government would reimburse terrorism claim payments subject to the insurer's deductible. The deductible is calculated as
 Cincinnati Financial Corporation - 2024 10-K - Page 106

 a percentage of subject written premiums for the preceding calendar year. Our deductible in 2024 was $763 million (20% of 2023 subject premiums), and we estimate it is $815 million (20% of 2024 subject premiums) for 2025.

 Reinsurance protection for the company's surety business is covered under a separate treaty with many of the same reinsurers that write the property casualty working treaties.

 Reinsurance protection for cyber coverage is also through a separate treaty. We offer cyber insurance as an affirmative coverage option on various insurance policies written on a direct basis and subsequently cede all of the related cyber insurance premiums to a reinsurer, therefore transferring substantially all of that risk.

 Effective in March 2024, we added a quota share reinsurance arrangement for personal lines earthquake risks in California that we insure through excess and surplus lines policies. We cede all of the related premiums to a reinsurer, therefore transferring substantially all of that risk. Ceded premiums for this treaty in 2024 totaled $1 million.

 Effective June 1, 2024, we restructured our reinsurance program for Cincinnati Re only, providing retrocession coverages with various triggers, exclusions and unique features. That program included property catastrophe excess of loss coverage with a total available aggregate limit of $60 million in excess of $80 million per occurrence. Coverage for Cincinnati Re only with a total available aggregate limit of $20 million in excess of $80 million per occurrence expired during the second quarter of 2024. That expiration also included the shared coverage for Cincinnati Re and the direct business applying to catastrophe losses in excess of $600 million.

 Reinsurance protection for Cincinnati Global's business is also provided through separate treaties.

 The Cincinnati Specialty Underwriters Insurance Company has separate property and casualty reinsurance treaties for 2025 through its parent, The Cincinnati Insurance Company. Primary components of the treaties include:
 • Property per risk treaty – The property treaty provides limits up to $6 million, which is adequate capacity for the risk profile we insure. It also includes protection for extra-contractual liability coverage losses. Cincinnati Specialty Underwriters retains the first $2 million of any policy loss. Losses between $2 million and $6 million are reinsured at 100% by The Cincinnati Insurance Company.
 • Casualty treaties – The casualty treaty is written on an excess of loss basis and provides limits up to $6 million, which is adequate capacity for the risk profile we insure. A second treaty layer of $5 million excess of $6 million is written to provide coverage for extra contractual obligations or clash exposures. The maximum retention for any one casualty loss is $2 million by Cincinnati Specialty Underwriters. Losses on a per occurrence basis between $2 million and $6 million and extra contractual and clash losses between $6 million and $11 million are reinsured at 100% by The Cincinnati Insurance Company.
 • Basket retention – Cincinnati Specialty Underwriters has purchased this coverage to limit their retention to $2 million in the event that the same occurrence results in both a property and a casualty loss.
 • Property catastrophe treaty – As a subsidiary of The Cincinnati Insurance Company, Cincinnati Specialty Underwriters is a named insured under our corporate property catastrophe treaty. All terms and conditions of this reinsurance coverage apply to policies underwritten by Cincinnati Specialty Underwriters.

 For property risks with limits exceeding $6 million or casualty risks with limits exceeding $6 million, underwriters place facultative reinsurance coverage on an individual certificate basis.

 Cincinnati Life, our life insurance subsidiary, purchases reinsurance under separate treaties with many of the same reinsurers that write the property casualty working treaties. Our corporate retention is $1 million on a single life. For our core term life insurance line of business, effective November 1, 2015, we increased our retention to $1 million for issue ages up to 61 years on new term life insurance sales, ceding the balance using excess over retention mortality coverage, and retaining the policy reserve. For issue ages 61 years or older, our retention is $500,000. Prior to November 1, 2015, and after 2004, we retain $500,000 per life. For term life insurance business written prior to 2005, we retain 10% to 25% of each term policy, not to exceed $500,000, ceding the balance of mortality risk and policy reserve.

 We did not renew the catastrophe reinsurance coverage on our life insurance operations that reimbursed us for covered net losses in excess of $14 million. No similar treaty replaced this expiring coverage.

 Cincinnati Financial Corporation - 2024 10-K - Page 110

 • Events, such as an epidemic, natural catastrophe or terrorism, that could hamper our ability to assemble our workforce at our headquarters location or work effectively in a remote environment
 Further, our insurance businesses are subject to the effects of changing social, global, economic and regulatory environments. Public and regulatory initiatives have included efforts to adversely influence and restrict premium rates, restrict the ability to cancel policies, impose underwriting standards and expand overall regulation. We also are subject to public and regulatory initiatives that can affect the market value for our common stock, such as measures affecting corporate financial reporting and governance. The ultimate changes and eventual effects, if any, of these initiatives are uncertain.

 ITEM 7A. Quantitative and Qualitative Disclosures About Market Risk

 Introduction
 Market risk is the potential for a decrease in securities value resulting from broad yet uncontrollable forces such as inflation, economic growth, interest rates, world political conditions or other widespread unpredictable events. It is comprised of many individual risks that, when combined, create a macroeconomic impact. The company accepts and manages risks in its investment portfolio as part of the means of achieving portfolio objectives. Some of the risks are:
 • Political – the potential for a decrease in value due to the real or perceived impact of governmental policies or conditions
 • Regulatory – the potential for a decrease in value due to the impact of legislative proposals or changes in laws or regulations
 • Economic – the potential for a decrease in value due to changes in general economic factors (recession, inflation, deflation, etc.)
 • Revaluation – the potential for a decrease in value due to a change in relative value (change in market multiple) of the market brought on by general economic factors
 • Interest-rate – the potential for a decrease in value of a security or portfolio due to its sensitivity to changes (increases or decreases) in the general level of interest rates
 Company-specific risk is the potential for a particular issuer to experience a decline in value due to the impact of sector or market risk on the holding or because of issues specific to the firm:
 • Fraud – the potential for a negative impact on an issuer's performance due to actual or alleged illegal or improper activity of individuals it employs
 • Credit – the potential for deterioration in an issuer's financial profile due to specific company issues, problems it faces in the course of its operations or industry-related issues
 • Default – the possibility that an issuer will not make a required payment (interest payment or return of principal) on its debt. Generally this occurs after its financial profile has deteriorated (credit risk) and it no longer has the means to make its payments

 The investment committee of the board of directors monitors the investment risk management process primarily through its executive oversight of our investment activities. We take an active approach to managing market and other investment risks, including the accountabilities and controls over these activities. Actively managing these market risks is integral to our operations and could require us to change the character of future investments purchased or sold or require us to shift the existing asset portfolios to manage exposure to market risk within acceptable ranges.

 Sector risk is the potential for a negative impact on a particular industry due to its sensitivity to factors that make up market risk. Market risk affects general supply or demand factors for an industry and affects companies within that industry to varying degrees.

 Fixed-Maturity Securities Investments
 For fixed-maturity securities, the inverse relationship between interest rates and bond prices leads to falling bond values during periods of increasing interest rates. We address this risk by attempting to construct a generally laddered maturity schedule that allows us to reinvest cash flows at prevailing rates. Although the potential for a worsening financial condition, and ultimately default, does exist with investment-grade corporate bonds, we address this risk by performing credit analysis and monitoring as well as maintaining a diverse portfolio of holdings.

 The primary risk related to high-yield corporate bonds is credit risk. A weak financial profile can lead to rating downgrades from the credit rating agencies, which can put further downward pressure on bond prices. Interest rate risk, while significant, is less of a factor with high-yield corporate bonds, as valuation is related more directly to underlying operating performance than to general interest rates. This puts more emphasis on the financial results achieved by the issuer rather than on general economic trends or statistics within the marketplace. We address this concern by analyzing issuer- and industry-specific financial results and by closely monitoring holdings within this asset class.

 The primary risks related to tax-exempt bonds are interest rate risk and political risk associated with the specific economic environment within the political boundaries of the issuing municipal entity. We address these concerns by focusing on municipalities' general-obligation debt and on essential-service bonds. Essential-service bonds derive a revenue stream from municipal services that are vital to the people living in the area (water service, sewer service, etc.). Another risk related to tax-exempt bonds is regulatory risk or the potential for legislative changes that would negate the benefit of owning tax-exempt bonds. We monitor regulatory activity for situations that may negatively affect current holdings and our ongoing strategy for investing in these securities.

 The final, less significant risk is our exposure to credit risk for a portion of the tax-exempt portfolio that has support from corporate entities. Examples are bonds insured by corporate bond insurers or bonds with interest payments made by a corporate entity through a municipal conduit or authority. Our decisions regarding these investments primarily consider the underlying municipal situation. The existence of third-party insurance is intended to reduce risk in the event of default. In circumstances in which the municipality is unable to meet its obligations, risk would be increased if the insuring entity were experiencing financial duress. Because of our diverse exposure and selection of higher-rated entities with strong financial profiles, we do not believe this is a material concern as we discuss in Item 1, Our Segments, Investments Segment.

 Interest Rate Sensitivity Analysis
 Because of our strong shareholders' equity, long-term investment horizon and ability to hold most fixed-maturity investments to maturity, we believe the company is well-positioned if interest rates were to rise. A higher rate environment would provide the opportunity to invest cash flow in higher-yielding securities, while reducing the likelihood of untimely redemptions of currently callable securities. While higher interest rates would be expected to increase the number of fixed-maturity holdings fair valued below 100% of amortized cost, we believe lower fixed-maturity security values due solely to interest rate changes would not signal a decline in credit quality.

 Cincinnati Financial Corporation - 2024 10-K - Page 113

 Our dynamic financial planning model uses analytical tools to assess market risks. As part of this model, the effective duration of the fixed-maturity portfolio is continually monitored by our investment department to evaluate the theoretical impact of interest rate movements.

 The table below summarizes the effect of an instantaneous hypothetical change in interest rates on the fair value of our fixed-maturity portfolio.

 The effective duration of the fixed-maturity portfolio was 5.0 years at year-end 2024, up from 4.3 years at year-end 2023. A 100-basis-point movement in interest rates would result in an approximately 5.1% change in the fair value of the fixed-maturity portfolio. Generally speaking, the higher a bond is rated, the more directly correlated movements in its fair value are to changes in the general level of interest rates, exclusive of call features. The fair values of average- to lower-rated corporate bonds are additionally influenced by the expansion or contraction of credit spreads.

 In the dynamic financial planning model, the selected interest rate change of 100 to 200 basis points represents our views of a shift in rates that is quite possible over a one-year period. The rates modeled should not be considered a prediction of future events as interest rates may be much more volatile in the future. The analysis is not intended to provide a precise forecast of the effect of changes in rates on our results or financial condition, nor does it take into account any actions that we might take to reduce exposure to such risks.

 Short-Term Investments
 Our short-term investments consist of commercial paper purchased within one year of maturity. We make short-term investments primarily with funds to be used to make upcoming cash payments, such as dividends, taxes or other corporate purposes. At year-end 2024, we had $298 million of short-term investments compared with none at year-end 2023.
 Cincinnati Financial Corporation - 2024 10-K - Page 114

 Equity Securities Investments
 Our equity portfolio is subject to a variety of risk factors encompassed under the umbrella of market risk. General economic swings influence the performance of the underlying industries and companies within those industries. Industry- and company-specific risks also have the potential to substantially affect the value of our portfolio. Our investment guidelines help address these risks by diversifying the portfolio and establishing parameters to help manage exposures.

 The table below summarizes the effect of hypothetical changes in market prices on the fair value of our equity portfolio.

 Our equity holdings represented $11.185 billion in fair value at year-end 2024. No holding had a fair value greater than 8.3% of our $10.836 billion common stock portfolio. We had 38 holdings (among nine different sectors) each with a fair value greater than $100 million. See Item 1, Our Segments, Investments Segment and Item 8, Note 2 of the Consolidated Financial Statements, for additional details on our holdings.

 The primary risks related to preferred stocks are similar to those related to investment-grade corporate bonds. Rising interest rates adversely affect market values due to the normal inverse relationship between interest rates and bond prices. Credit risk exists due to the subordinate position of preferred stocks in the capital structure. We minimize this risk by primarily purchasing investment-grade preferred stocks of issuers with a strong history of paying a common stock dividend.

 Cincinnati Financial Corporation - 2024 10-K - Page 115

 Application of Asset Impairment Policy
 As discussed in Item 7, Critical Accounting Estimates, Asset Impairment, our fixed-maturity investment portfolio is evaluated for credit-related impairments. The company's asset impairment committee monitors a number of significant factors for indications of investments with a fair value below the carrying amount that may not be recoverable. The application of our impairment policy resulted in write-downs of impaired securities intended to be sold that reduced our income before income taxes by less than $1 million in 2024, $4 million in 2023 and $5 million in 2022. Impairments are discussed in Item 7, Investments Results.

 We expect the number of fixed-maturity and short-term securities with a fair value below 100% of amortized cost to fluctuate as interest rates rise or fall and credit spreads expand or contract due to prevailing economic conditions. Further, amortized cost for some securities have been revised due to impairment charges recognized in prior periods. At year-end 2024, 3,723 of the 5,090 fixed-maturity and short-term securities we owned had a fair value below 100% of amortized cost compared with 2,840 of the 4,738 at year-end 2023 and 3,272 of the 4,521 at year-end 2022.

 The 3,723 holdings fair valued below amortized cost at year-end 2024 represented 75.9% of our fixed-maturity and short-term investments portfolio and $631 million in unrealized losses.
 •2,874 of these holdings were fair valued between 90% and 100% of amortized cost. The value of these securities fluctuates primarily because of changes in interest rates. The fair value of these 2,874 securities was $10.993 billion at year-end 2024, and they accounted for $272 million in unrealized losses.
 •830 of these holdings were fair valued between 70% and 90% of amortized cost. The fair value of these holdings was $1.485 billion, and they accounted for $344 million in unrealized losses.
 •19 of these holdings had a fair value below 70% of amortized cost. The fair value of these holdings was $28 million, and they accounted for $15 million in unrealized losses.

 ITEM 8. Financial Statements and Supplementary Data

 Responsibility for Financial Statements
 We have prepared the consolidated financial statements of Cincinnati Financial Corporation and our subsidiaries for the year ended December 31, 2024, in accordance with accounting principles generally accepted in the United States of America (GAAP).

 We are responsible for the integrity and objectivity of these financial statements. The amounts, presented on an accrual basis, reflect our best estimates and judgment. These statements are consistent in all material aspects with other financial information in the Annual Report on Form 10-K. Our accounting system and related internal controls are designed to assure that our books and records accurately reflect the company's transactions in accordance with established policies and procedures as implemented by qualified personnel.

 Our board of directors has established an audit committee of independent outside directors. We believe these directors are free from any relationships that could interfere with their independent judgment as audit committee members.

 The audit committee meets periodically with management, our independent registered public accounting firm and our internal auditors to discuss how each is handling its respective responsibilities. The audit committee reports its findings to the board of directors. The audit committee recommends to the board the annual appointment of the independent registered public accounting firm. The audit committee reviews with this firm the scope of the audit assignment and the adequacy of internal controls and procedures.

 Deloitte & Touche LLP, our independent registered public accounting firm, audited the consolidated financial statements of Cincinnati Financial Corporation and subsidiaries for the year ended December 31, 2024. Deloitte & Touche LLP met with our audit committee to discuss the results of its audit. They have the opportunity to discuss the adequacy of internal controls and the quality of financial reporting without management present.

 Management's Annual Report on Internal Control Over Financial Reporting
 The management of Cincinnati Financial Corporation and its subsidiaries is responsible for establishing and maintaining adequate internal controls, designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America (GAAP). The company's internal control over financial reporting includes those policies and procedures that:
 • Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;
 • Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP and that receipts and expenditures of the company are being made only in accordance with authorizations of management and the directors of the company; and
 • Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

 All internal control systems, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention of overriding controls. Accordingly, even effective internal control can provide only reasonable assurance with respect to financial statement preparation and presentation. Further, because of changes in conditions, the effectiveness of internal control may vary over time.

 The company's management assessed the effectiveness of the company's internal control over financial reporting as of December 31, 2024, as required by Section 404 of the Sarbanes Oxley Act of 2002. Management's assessment was based on the criteria established in the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and was designed to provide reasonable assurance that the company maintained effective internal control over financial reporting as of December 31, 2024. The assessment led management to conclude that, as of December 31, 2024, the company's internal control over financial reporting was effective based on those criteria.

 The company's independent registered public accounting firm has issued an audit report on our internal control over financial reporting as of December 31, 2024.

 Report of Independent Registered Public Accounting Firm
 To the Shareholders and Board of Directors of Cincinnati Financial Corporation

 Opinions on the Financial Statements and Internal Control over Financial Reporting
 We have audited the accompanying consolidated balance sheets of Cincinnati Financial Corporation and subsidiaries (the "Company") as of December 31, 2024 and 2023, the related consolidated statements of income, comprehensive income, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2024, and the related notes and the schedules listed in the Index at Item 15(b) (collectively referred to as the "financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
 In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

 Basis for Opinions
 The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these financial statements and an opinion on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

 Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

 Definition and Limitations of Internal Control over Financial Reporting
 A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

 Cincinnati Financial Corporation - 2024 10-K - Page 121

 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

 Critical Audit Matter
 The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

 Property and Casualty Insurance Loss and Loss Expense Reserves — Refer to Note 4 to the financial statements.
 Critical Audit Matter Description
 The Company's property and casualty insurance loss and loss expense reserves for long-tailed lines of business, such as workers' compensation, commercial casualty and certain other liability lines (referred to as "loss and loss expense reserves"), are determined by the Company using actuarial methods, models, assumptions, and judgment to estimate the reserves ("actuarial estimates") required to pay for and settle all outstanding insured claims, including incurred but not reported (IBNR) claims, as of the financial statement date. The actuarial estimates of loss and loss expense reserves are subject to review and adjustment by Company management.

 Loss and loss expense reserves are inherently uncertain as to timing and amount and the recorded loss and loss expense reserves may vary materially from the actual ultimate cost of claims. Given the subjectivity in estimating ultimate loss and loss expense reserves, due to uncertainties concerning the future emergence of loss and loss expenses, inflation trends, and the judicial environment, among other factors, auditing loss and loss expense reserves involved an especially high degree of auditor judgment, including the need to involve our actuarial specialists.

 How the Critical Audit Matter Was Addressed in the Audit
 Our audit procedures related to loss and loss expense reserves included the following, among others:
 • We tested the effectiveness of controls related to loss and loss expense reserves, including those over the review of actuarial methods, models, assumptions and judgments used, and management's review of the estimates.
 • We tested the underlying data that served as the basis for the actuarial analyses, including historical claims data, to test the reasonableness of key inputs to the actuarial estimates.
 • With the assistance of our actuarial specialists, we used the Company's claims data and other inputs, to develop a range of independent estimates for the loss and loss expense reserves. We used these independent estimates to assess the reasonableness of the Company's reserves by comparing our estimates to the Company's recorded loss and loss expense reserves.
 • We compared the Company's prior year estimates of expected incurred losses to actual experience during the current year to identify potential bias in the determination of loss and loss expense reserves.

 Notes to Consolidated Financial Statements

 NOTE 1 – Summary of Significant Accounting Policies

 Nature of Operations
 Cincinnati Financial Corporation (CFC) operates through The Cincinnati Insurance Company and Cincinnati Global Underwriting Ltd. SM (Cincinnati Global) insurance subsidiaries and two complementary subsidiary companies.

 The Cincinnati Insurance Company leads our insurance group that also includes two subsidiaries: The Cincinnati Casualty Company and The Cincinnati Indemnity Company. This group markets a broad range of standard market commercial and personal policies. The group focuses on delivery of quality customer service to our select group of 2,175 independent insurance agencies with 3,355 reporting locations across 46 states. Other subsidiaries of The Cincinnati Insurance Company include: The Cincinnati Life Insurance Company, which markets life insurance and fixed annuities; and The Cincinnati Specialty Underwriters Insurance Company, which offers excess and surplus lines property casualty insurance products. The Cincinnati Insurance Company also conducts the business of our reinsurance assumed operations, Cincinnati Re.

 The two CFC complementary subsidiaries are CSU Producer Resources Inc., which provides insurance brokerage services to our independent agencies so their clients can access our excess and surplus lines insurance products, and CFC Investment Company, which offers commercial leasing and financing services to our agents, their clients and other customers.

 Basis of Presentation
 Our consolidated financial statements include the accounts of the parent and its wholly owned subsidiaries and are presented in conformity with accounting principles generally accepted in the United States of America (GAAP). Foreign exchange rates related to Cincinnati Global's operations did not have a material impact to our consolidated financial statements. All intercompany balances and transactions have been eliminated in consolidation.

 The preparation of the consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Our actual results could differ from those estimates.

 Our portfolio investments are primarily in publicly traded fixed-maturity, equity security and short-term investments. Fixed-maturity (taxable bonds, including redeemable preferred equities, tax-exempt bonds and asset-backed securities) and short-term (commercial paper purchased within one year of maturity) investments classified as available for sale and equity security investments (common and nonredeemable preferred equities) are recorded at fair value in the consolidated financial statements. Changes in fair value of fixed-maturity and short-term investments are reported in other comprehensive income while changes in fair value of equity securities are reported in net income. The number of fixed-maturity securities with fair values below 100% of amortized cost can be expected to fluctuate as interest rates rise or fall. Because of our strong capital and long-term investment horizon, our general intent is to hold fixed-maturity investments until maturity, regardless of short-term fluctuations in fair values.

 An available for sale fixed maturity is impaired if the fair value of the security is below amortized cost. The impaired loss is charged to net income when we have the intent to sell the security or it is more likely than not we will be required to sell the security before recovery of the amortized cost. For impaired securities we intend to hold, an allowance for credit related losses is recorded in investment losses when the company determines a credit loss has been incurred based on certain factors such as adverse conditions, credit rating downgrades or failure of the issuer to make scheduled principal or interest payments. A credit loss is determined using a discounted cash flow analysis by comparing the present value of expected cash flows with the amortized cost basis, limited to the difference between fair value and amortized cost. Noncredit losses are recognized in other comprehensive income as a change in unrealized gains and losses on investments. As securities are sold, we recognize the gain or loss in net income based on the trade date.

 Cincinnati Financial Corporation - 2024 10-K - Page 128

 Included within our other invested assets were $ 567 million and $ 434 million of private equity investments, $ 94 million and $ 66 million of real estate through direct property ownership and development projects in the United States, $ 36 million and $ 33 million of life policy loans and $ 16 million and $ 44 million held on deposit at Lloyd's at December 31, 2024 and 2023, respectively. The private equity investments provide their financial statements to us and generally report investments on their balance sheets at fair value. We use the equity method of accounting for private equity and real estate development investments. Lloyd's deposits primarily consist of highly liquid short-term investment instruments. Life policy loans are carried at the receivable value.

 Investment income, net of expenses, consists mainly of interest and dividends. We record interest on an accrual basis and record dividends at the ex-dividend date. We amortize premiums and discounts on fixed-maturity securities using the effective interest method over the expected life of the security.

 Fair Value Disclosures
 Fair value is defined as the exit price or the amount that would be (1) received to sell an asset or (2) paid to transfer a liability in an orderly transaction between marketplace participants at the measurement date. When determining an exit price, we rely upon observable market data whenever possible. We primarily base fair value for investments in equity, fixed-maturity and short-term securities (including assets held in separate accounts) on quoted market prices or on prices from the company's nationally recognized pricing vendors, outside resources that supply global securities pricing, dividend, corporate action and descriptive information to support fund pricing, securities operations, research and portfolio management. The company obtains and reviews the pricing services' valuation methodologies and related inputs and validates these prices by replicating a sample across each asset class using a discounted cash flow model. When a price is not available from these sources, as in the case of securities that are not publicly traded, we determine the fair value using various inputs including quotes from independent brokers. The fair value of investments not priced by the company's nationally recognized pricing vendors is immaterial.

 For the purpose of Accounting Standards Codification (ASC) 825, Financial Instruments disclosure, we estimate the fair value of our long-term senior notes on market pricing of similar debt instruments that are actively trading. We estimate the fair value of our note payable on the year-end outstanding balance because it is short term and tied to a variable interest rate. We estimate the fair value of liabilities for investment contracts and annuities using discounted cash flow calculations across a wide range of economic interest rate scenarios with a provision for our nonperformance risk. We estimate the fair value for policyholder loans on insurance contracts using a discounted cash flow model. Determination of fair value for structured settlements assumes the discount rates used to calculate the present value of expected payments are the risk-free spot rates plus an A3 rated bond spread for financial issuers at December 31, 2024, to account for nonperformance risk. See Note 3, Fair Value Measurements, for further details.

 Cash and Cash Equivalents
 Cash and cash equivalents are highly liquid instruments that include liquid debt instruments with original maturities of less than three months. These are carried at cost, which approximates fair value.

 Property Casualty Insurance
 The consolidated property casualty companies actively write property casualty insurance through independent agencies in 46 states. Our 10 largest states generated 50.1 % of total earned premiums in 2024 and 2023. Ohio, our largest state, accounted for 13.1 % and 13.4 % of total earned premiums in 2024 and 2023, respectively. Illinois, New York, North Carolina and Pennsylvania each accounted for between 4 % and 6 % of total earned premiums in 2024. Our largest single agency relationship accounted for approximately 0.5 % of our total property casualty earned premiums in 2024. No aggregate agency relationship locations under a single ownership structure accounted for more than 8 % of our total property casualty earned premiums in 2024. We record revenues for installment charges as fee revenues in the consolidated statements of income.

 Property casualty written premiums are deferred and recorded as earned premiums primarily on a pro rata basis over the terms of the policies. We record as unearned premiums the portion of written premiums that applies to unexpired policy terms. Expenses associated with successfully acquiring insurance policies – commissions, premium taxes and underwriting costs – are deferred and amortized over the terms of the policies. We assess recoverability of deferred acquisition costs at a level consistent with the way we acquire, service and manage insurance policies and measure profitability. We analyze our acquisition cost assumptions to reflect actual experience, and we evaluate potential premium deficiencies.

 Cincinnati Financial Corporation - 2024 10-K - Page 129

 Certain property casualty policies are not entered into policy underwriting systems as of the effective date of coverage. An estimate is recorded for these unprocessed written premiums. A large majority of the estimate is unearned and has no material impact on earned premiums.

 An allowance for credit losses on uncollectible property casualty premiums is updated and reviewed on a quarterly basis. The allowance for credit losses was $ 18 million, $ 16 million and $ 13 million at December 31, 2024, 2023 and 2022, respectively. Changes in the amount for each period were immaterial.

 We establish reserves to cover the expected cost of claims, losses and expenses related to investigating, processing and resolving claims. Although the appropriate amount of reserves is inherently uncertain, we base our decisions on past experience and current facts. Reserves are based on claims reported prior to the end of the year and estimates of incurred but not reported (IBNR) claims. We regularly review and update reserves using the most current information available. Any resulting adjustments are reflected in current calendar year insurance losses and policyholder benefits. We estimate that we may recover some of our costs through salvage and subrogation.

 Policyholder Dividends
 Certain workers' compensation policies include the possibility of a policyholder earning a return of a portion of premium in the form of a policyholder dividend. The dividend generally is calculated by determining the profitability of a policy year along with the associated premium. We reserve for all probable future policyholder dividend payments. We record policyholder dividends as other underwriting expenses.

 Life Insurance
 We offer several types of life insurance and we account for each according to the duration of the contract. Short-duration life and health contracts are written to cover claims that arise during a short, fixed term of coverage. We generally have the right to change the amount of premium charged or cancel the coverage at the end of each contract term. We record premiums for short-duration life and health contracts similarly to property casualty contracts.

 Long-duration contracts are written to provide coverage for an extended period of time. Traditional long-duration contracts require policyholders to pay scheduled gross premiums, generally not less frequently than annually, over the term of the coverage. Premiums for these contracts, such as whole life insurance, are recognized as revenue when due. Some traditional long-duration contracts, such as ten-pay whole life insurance, have premium payment periods shorter than the period over which coverage is provided. For these contracts, the excess of premium over the amount required to pay expenses and benefits is recognized over the term of the coverage rather than over the premium payment period.

 We establish reserves for traditional long-duration contracts, including term, whole life and other products, based on the present value of future benefits and claim expenses less the present value of future net premiums. Net premium is the portion of gross premium required to provide for all benefits and claim expenses. We estimate future benefits and claim expenses and net premium using certain cash flow assumptions including mortality, morbidity and lapse rates as well as a discount rate assumption. The cash flow assumptions are established based on our current expectations and are reviewed annually to determine any necessary updates. These assumptions are also updated on an interim basis if evidence suggests that they should be revised. We use both our own experience and industry experience, adjusted for historical trends, in arriving at our cash flow assumptions. The discount rate assumption is based on upper-medium grade fixed-income instrument yields (market value discount rates) and is updated quarterly. Certain assumptions, including the mortality, lapse and long-term interest rate reversion targets, were updated in 2024 as part of our annual assumption unlocking. See Note 5, Life Policy and Investment Contract Reserves, for further detail regarding the measurement impact on traditional long-duration contract reserves due to changes in the inputs, judgments and assumptions during the period.

 We also offer universal life, deferred annuity and other investment contracts. Universal life contracts are long-duration contracts for which contractual provisions are not fixed, unlike whole life insurance. Universal life contracts allow policyholders to vary the amount of premium, within limits, without our consent. However, we may vary the mortality, expense charges and the interest crediting rate, within limits, used to accumulate policy values. We do not record universal life premiums as revenue. Instead we recognize as revenue the mortality charges, administration charges and surrender charges when assessed. Some of our universal life contracts assess administration charges in the early years of the contract that are compensation for services we will provide in the later years of the contract. These administration charges are deferred and are recognized over the period when we provide those future
 Cincinnati Financial Corporation - 2024 10-K - Page 130

 services. Deferred annuities provide regular income payments to annuitants once certain criteria are met. During the deferral period, payments made by the annuitants under the contract accumulate at the crediting rate declared by the company but not less than a contract-specified guaranteed minimum interest rate. We also do not record deferred annuity premiums as revenue.

 We establish reserves for our universal life, deferred annuity and other investment contracts equal to the cumulative account balances, which include premium deposits plus credited interest less charges and withdrawals. Some of our universal life insurance policies contain no-lapse guarantee provisions. For these policies, we establish a reserve in addition to the account balance based on expected no-lapse guarantee benefits and expected policy assessments.

 We capitalize acquisition costs associated with successfully acquiring traditional and universal life long-duration contracts. We charge these capitalized costs to expenses on a constant-level basis that approximates straight-line amortization over the expected term of the related contracts.

 An allowance for credit losses on uncollectible life insurance premiums is updated and reviewed on a quarterly basis. At December 31, 2024, 2023 and 2022, the allowance, including changes in the amount for each period, was immaterial.

 Separate Accounts
 We have issued universal life contracts with guaranteed minimum returns, referred to as bank-owned life insurance contracts (BOLIs). A BOLI is designed so the bank is the policy owner and the policy beneficiary. We legally segregate and record as separate accounts the assets and liabilities for certain BOLIs, when required by the specific contract provisions. We guarantee minimum investment returns, account values and death benefits for our separate account BOLIs. Our other BOLIs are general account products.

 We carry the assets of separate account BOLIs at fair value. The liabilities on separate account BOLIs primarily are carried at an amount equal to the contract holders' account value, plus any cumulative unrealized gains on the related assets impacting separate account liabilities. The contract holders' account value exceeded the current fair value of the BOLI invested assets and cash by approximately $ 42 million and $ 43 million at December 31, 2024 and 2023, respectively.

 Generally, investment income and investment gains and losses of the separate accounts accrue directly to the contract holder, and we do not include them in the consolidated statements of income. Revenues and expenses related to separate accounts consist of contractual fees and mortality, surrender and expense risk charges. Also, each separate account BOLI includes a negotiated capital gain and loss sharing arrangement between the company and the bank. A percentage of each separate account's investment gains and losses representing contract fees and assessments accrues to us and is transferred from the separate account to our general account and is recognized as revenue or expense. We record as revenues separate account investment management fees in fee revenues of the consolidated statements of income.

 Reinsurance
 The Cincinnati Insurance Company offers reinsurance assumed for casualty (predominantly domestic exposure), specialty and property (worldwide exposure). Treaties are written on a pro rata and excess of loss basis. We also continue to assume risk with limited exposure as a reinsurer for involuntary state pools.

 Written premium is recorded, net of contract specific retrocessions, on an ultimate estimate basis and primarily earned on a pro rata basis over the coverage period of the treaty. Expenses are recorded as per contract terms and deferred over the earning period of the premium.

 We establish known loss reserves when reported. We establish reserves for losses in excess of reported activity in the form of IBNR. Reserves are established using actuarial analysis, which includes models and methods traditionally used for the types of exposures written. We establish reserves for event specific occurrences using modeling data and company specific data when available.

 We enter into other reinsurance transactions to reduce risk and uncertainty by buying property casualty reinsurance and retrocessional reinsurance as well as life reinsurance. Reinsurance and retrocessional reinsurance contracts do
 Cincinnati Financial Corporation - 2024 10-K - Page 131

 not relieve us from our obligation to policyholders, but rather help protect our financial strength to perform that duty. All of these ceded reinsurance contracts transfer the economic risk of loss.

 Premiums that we cede are deferred and recorded as earned premiums on a pro rata basis over the terms of the contracts. We estimate loss amounts recoverable from our reinsurers based on the reinsurance policy terms. Historically, our claims with reinsurers have been paid.

 An allowance for credit losses on uncollectible reinsurance premiums and recoverable assets is updated and reviewed on a quarterly basis. At December 31, 2024, 2023 and 2022, the allowances, including changes in the amount for each period, were immaterial.

 Income Taxes
 We calculate deferred income tax liabilities and assets using tax rates in effect when temporary differences in taxable income and financial statement income are expected to reverse. We recognize deferred income taxes for numerous temporary differences between our taxable income and financial statement income and other changes in shareholders' equity. Such temporary differences relate primarily to unrealized gains and losses on investments and differences in the recognition of deferred acquisition costs, unearned premiums, insurance reserves, international earnings and basis differences in the carrying value of investments held. We charge deferred income taxes associated with balances that impact other comprehensive income, such as unrealized gains and losses of fixed-maturity investments, to shareholders' equity in accumulated other comprehensive income (AOCI). We charge deferred taxes associated with other differences to income.

 See Note 11, Income Taxes, for further detail on our uncertain tax positions and other income tax items. Although no Internal Revenue Service (IRS) penalties currently are accrued, if incurred, they would be recognized as a component of income tax expense.

 Earnings per Share
 Net income per common share is based on the weighted average number of common shares outstanding during each of the respective years. We calculate net income per common share (diluted) assuming the exercise or conversion of share based awards using the treasury stock method.

 Land, Building and Equipment
 We record land at cost, and record building and equipment at cost less accumulated depreciation. Equipment held under finance leases also is classified as property and equipment with the related lease obligations recorded as liabilities. We capitalize and amortize costs for internally developed computer software during the application development stage. These costs generally consist of external consulting fees and internal payroll-related costs. Our depreciation is based on estimated useful lives (ranging from three to 39.5 years) using straight-line and accelerated methods. Depreciation expense was $ 34 million for 2024, $ 30 million for 2023 and $ 33 million for 2022. We review our accumulated depreciation for our building, equipment and software assets and write off fully depreciated assets for obsolescence and nonuse. We monitor land, building and equipment and software assets for potential impairments. Indicators of potential impairments may include a significant decrease in the fair values of the assets, considerable cost overruns on projects, a change in legal factors or business climate or other factors that indicate that the carrying amount may not be recoverable or useful. There were no recorded land, building and equipment impairments for 2024, 2023 or 2022.

 Finance Receivables
 Our leasing subsidiary provides auto and equipment direct financing (leases and loans) to commercial and individual clients. We generally transfer ownership of the property to the client as the terms of the leases expire. Our lease contracts contain bargain purchase options. We account for these leases and loans as sales-type leases. We capitalize and amortize lease or loan origination costs over the life of the financing, using the effective interest method. These costs may include, but are not limited to finder fees, broker fees, filing fees and the cost of credit reports. We record income as other revenues over the financing term using the effective interest method in the consolidated statements of income. An allowance for credit losses on finance receivables is updated and reviewed on a quarterly basis. At December 31, 2024, 2023 and 2022, the allowance, including changes in the amount for each period, was immaterial.

 Cincinnati Financial Corporation - 2024 10-K - Page 132

 Employee Benefit Pension Plan
 We sponsor a qualified defined benefit pension plan that was modified during 2008. We closed entry into the pension plan, and only participants 40 years of age or older could elect to remain in the plan. Our pension expenses are based on certain actuarial assumptions and also are composed of several components that are determined using the projected unit credit actuarial cost method. Refer to Note 13, Employee Retirement Benefits, for more information about our defined benefit pension plan.

 Share-Based Compensation
 We grant qualified and nonqualified share-based compensation under authorized plans. The stock options generally vest on a graded scale over three years following the date of grant and are exercisable over 10 -year periods. We grant service-based restricted stock units that cliff vest three years after the date of grant as well as service-based restricted stock units that vest ratably over the three -year vesting term. We also grant performance-based restricted stock units that vest if certain market conditions are attained. In 2024, the CFC compensation committee approved share-based awards including incentive stock options, nonqualified stock options, service-based restricted and performance-based restricted stock units. See Note 17, Share-Based Associate Compensation Plans, for further details.

 Goodwill and Intangible Assets
 We recognize goodwill and intangible assets generated through acquisitions within other assets in the consolidated balance sheets. Goodwill arises when the fair value of consideration transferred exceeds the fair value of the net identifiable assets acquired at the acquisition date. Goodwill and intangible assets with an indefinite life are not amortized. Intangible assets with a definite life are amortized on a straight-line basis over the estimated useful lives as follows: broker relationships, over 15 years; internally developed technology, over five years, and which became fully amortized during 2024. We test for impairments on an annual basis or more frequently if events or circumstances indicate that the asset might be impaired. The company performed its annual impairment test on goodwill and intangibles at September 30, which did not result in the recognition of an impairment loss. Within Cincinnati Global, and included in Other, the company held goodwill of $ 30 million and intangible assets with an indefinite life of $ 31 million at December 31, 2024 and 2023, respectively.

 Subsequent Events
 In January 2025, a series of wildfires began to spread in southern California, particularly in areas surrounding Los Angeles.

 Related to these wildfires, we currently estimate first quarter 2025 pretax catastrophe losses of approximately $ 450 million to $ 525 million, net of reinsurance recoveries, with approximately 73 % of the impact to our personal lines insurance segment, 24 % to Cincinnati Re and 3 % to our Cincinnati Global operations. On a gross basis, these first quarter 2025 pretax catastrophe losses are estimated to be approximately $ 950 million to $ 1.15 billion. This estimate includes assessments from the California Fair Access to Insurance Requirements (FAIR) plan.

 We reinstated the applicable layers of our primary property catastrophe reinsurance treaty coverage and our reinsurance program for Cincinnati Re only. As a result, we will cede additional premiums to our reinsurers. The payments for additional ceded premiums will be partially offset by additional premiums received by Cincinnati Re from treaties reinstated for its reinsurance assumed operations. The estimated net effect on first quarter earned premiums is a decrease of $ 50 million to $ 60 million.

 After reinstating coverage for reinsurance to provide coverage for catastrophic events, our primary property catastrophe reinsurance treaty provides the same coverage that was effective on January 1, 2025. The remaining coverage from our reinsurance program for Cincinnati Re provides a total available aggregate limit up to $ 38 million in excess of $ 80 million per occurrence.

 There were no subsequent events requiring adjustment to the 2024 consolidated financial statements and, with the exception of the above disclosure, no additional disclosures required in the notes to our consolidated financial statements.

 Adopted Accounting Updates

 ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
 In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07 enhances reportable segment disclosures by requiring entities to disclose significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within the reported measure of profit or loss. This ASU also requires disclosure of the title and position of the CODM as well as a description of how the reported measure of profit or loss is used to assess segment performance and allocate resources. The effective date of ASU 2023-07 is for annual reporting periods beginning after December 15, 2023, and interim reporting periods within annual periods beginning after December 15, 2024, and should be applied retrospectively to all prior periods presented. We retrospectively adopted this ASU effective December 31, 2024. The adoption did not have a material impact on our company's consolidated financial position, results of operations or cash flows, but the ASU required additional disclosure in Note 18, Segment Information, to these consolidated financial statements and will require additional disclosure in our interim financial statements in 2025.

 Pending Accounting Updates

 ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures
 In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 enhances the transparency and decision usefulness of income tax disclosures by requiring entities to disclose specific categories within their rate reconciliation as well as additional items within those categories above a prescribed threshold. This ASU also requires disclosure of the amount of income taxes paid (net of refunds received) disaggregated by federal, state and foreign taxes as well as additional items within those categories above a prescribed threshold. The effective date of ASU 2023-09 is for annual reporting periods beginning after December 15, 2024, and should be applied prospectively with retrospective application permitted. The ASU has not yet been adopted and will not have a material impact on our company's consolidated financial position, results of operations or cash flows, but the ASU will require additional disclosures in our annual financial statements.

 ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses
 In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 requires increased quantitative disclosure of certain categories of expenses contained within relevant expense captions. A relevant expense caption is an expense caption presented on the face of the income statement that contains employee compensation, depreciation, intangible asset amortization and other captions. The ASU also requires a qualitative description of the remaining amount of relevant expense captions as well as total selling expenses on an interim basis and how selling expenses are defined on an annual basis. The effective date of ASU 2024-03 is for annual periods beginning after December 15, 2026, and interim reporting periods within annual periods beginning after December 15, 2027. The ASU should be applied prospectively with retrospective application and early adoption permitted. The ASU has not yet been adopted and will not have a material impact on our company's consolidated financial position, results of operations or cash flows, but the ASU will require additional disclosures in our annual and interim financial statements.

 The decrease in net unrealized investment losses in our fixed-maturity portfolio at December 31, 2024, is primarily due to a tightening of corporate credit spreads as well as realized losses on sales of some lower-yielding fixed maturities. Our asset-backed securities had an average rating of Aa1/AA and Aa3/AA- at December 31, 2024 and 2023, respectively.

 NOTE 3 – Fair Value Measurements

 Fair Value Hierarchy
 The fair value hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within different levels of the fair value hierarchy, the lowest observable input that has a significant impact on fair value measurement is used. Our valuation techniques have not changed from those used at December 31, 2023, and ultimately management determines fair value. Financial instruments reported at fair value in our consolidated financial statements are categorized based upon the following characteristics or inputs to the valuation techniques:

 • Level 1 – Financial assets and liabilities for which inputs are observable and are obtained from reliable quoted prices for identical assets or liabilities in active markets. This is the most reliable fair value measurement and includes, for example, active exchange-traded equity securities.
 • Level 2 – Financial assets and liabilities for which values are based on quoted prices in markets that are not active or for which values are based on similar assets and liabilities that are actively traded. This also includes pricing models for which the inputs are corroborated by market data.
 The technique used for the Level 2 fixed-maturity securities is the application of market-based modeling. The inputs used for all classes of fixed-maturity securities listed in the table below include relevant market information by asset class, trade activity of like securities, marketplace quotes, benchmark yields, spreads off benchmark yields, interest rates, U.S. Treasury or swap curves, yield to maturity and economic events. Specific to asset-backed securities, key inputs also include prepayment and default projections based on performance of the underlying collateral and current market data. Level 2 fixed-maturity securities are priced by a nationally recognized pricing vendor.
 The Level 2 nonredeemable preferred equities technique used is the application of market-based modeling. The inputs used, similar to those used by the pricing vendor for our fixed-maturity securities, include relevant market information, trade activity of like securities, yield to maturity, corporate action notices and economic events. Level 2 nonredeemable preferred equities are priced by a nationally recognized pricing vendor.
 • Level 3 – Financial assets and liabilities for which values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Level 3 inputs include the following:
 Quotes from brokers or other external sources that are not considered binding;
 Quotes from brokers or other external sources where it cannot be determined that market participants would in fact transact for the asset or liability at the quoted price; or
 Quotes from brokers or other external sources where the inputs are not deemed observable.

 Cincinnati Financial Corporation - 2024 10-K - Page 138

 The following tables illustrate the fair value hierarchy for those assets measured at fair value on a recurring basis at December 31, 2024 and 2023. We do not have any liabilities carried at fair value.

 Fair value of the note payable was determined based upon the outstanding balance at December 31, 2024 and 2023, because it is short term and tied to a variable interest rate. Fair value of the long-term debt was determined under the fair value measurements and disclosure accounting rules based on market pricing of similar debt instruments that are actively traded. We determine fair value for our debt the same way that we value corporate fixed maturities in our investment portfolio. Fair value can vary with macroeconomic conditions. Regardless of the fluctuations in fair value, the outstanding principal amount of our long-term debt was $ 793 million at December 31, 2024 and 2023. None of the long-term debt is encumbered by rating triggers. The note payable and long-term debt were classified as Level 2 as an active market does not exist, but fair value is determined based on observable inputs.

 Outstanding principal and interest for these life policy loans totaled $ 36 million and $ 33 million at December 31, 2024 and 2023, respectively. To determine the fair value, we make the following significant assumptions: (1) the discount rates used to calculate the present value of expected payments are the risk-free spot rates, as nonperformance risk is minimal; and (2) the loan repayment rate by which policyholders pay off their loan balances is in line with past experience.

 Recorded reserves for the deferred annuities were $ 595 million and $ 656 million at December 31, 2024 and 2023, respectively. Recorded reserves for the structured settlements were $ 116 million and $ 123 million at December 31, 2024 and 2023, respectively.

 Fair values for deferred annuities were calculated based upon internally developed models because active markets and observable inputs do not exist. To determine the fair value, we made the following significant assumptions: (1) the discount rates used to calculate the present value of expected payments are the risk-free spot rates plus an A3 rated bond spread for financial issuers at December 31, 2024 and 2023, to account for nonperformance risk; (2) the rate of interest credited to policyholders is the portfolio net earned interest rate less a spread for expenses and profit; and (3) additional lapses occur when the credited interest rate is exceeded by an assumed competitor credited rate, which is a function of the risk-free rate of the economic scenario being modeled.

 Fair values for structured settlements were calculated based on internally developed models which assume the discount rates used to calculate the present value of expected payments are the risk-free spot rates plus an A3 rated bond spread for financial issuers at December 31, 2024 and 2023, to account for nonperformance risk. The structured settlements were classified as Level 2, as an active market does not exist, but fair value is based on observable inputs.

 NOTE 4 – Property Casualty Loss and Loss Expenses
 We use actuarial methods, models, assumptions and judgment to estimate, as of a financial statement date, the property casualty loss and loss expense reserves required to pay for and settle all outstanding insured claims, including IBNR claims, as of that date. The actuarial estimate is subject to review and adjustment by an inter-departmental committee that includes actuarial, claims, underwriting, loss prevention and finance management. This committee is familiar with relevant company and industry business, claims and underwriting trends, as well as general economic and legal trends that could affect future loss and loss expense payments. The amount we will actually have to pay for claims can be highly uncertain. This uncertainty, together with the size of our reserves, makes the loss and loss expense reserves our most significant estimate.

 Our reserving process takes into account known facts and interpretations of circumstances and factors including the type of claim, policy provisions pertaining to each claim, potential subrogation or salvage recoverable, large loss activity and trends, new business activity, judicial decisions, economic conditions, changes in law and regulation and product and underwriting changes. There have been no significant changes in methodologies and assumptions used in calculating loss and loss expense reserves for all years presented. There were no material additional premiums or return premiums accrued for as a result of prior-year effects.

 Our claims representatives establish case reserves when claims are reported to provide for our unpaid loss and loss expense obligation associated with individual claims.

 For events designated as natural catastrophes resulting in losses incurred related to direct premiums, we calculate IBNR reserves directly as a result of an estimated claim counts and estimated average dollar amount per claim for each event. Once individual case reserves are established for a catastrophe event, we reduce the IBNR reserves.

 Our actuarial staff uses generally accepted actuarial methods and models to derive ultimate loss and IBNR reserve estimates. The time interval between a claims occurrence and its settlement is one of the crucial attributes when estimating ultimate losses and IBNR reserves.

 Due to the uncertainties inherent with loss reserves, our ultimate loss experience could prove better or worse than what our carried reserves reflect. To the extent that reserves are inadequate and are required to be increased, the amount of the increase is a charge in that period, raising our loss and loss expense ratio and reducing earnings. To the extent that reserves are redundant and are required to be released, the amount of the release is a credit in that period, reducing our loss and loss expense ratio and increasing earnings.

 The reserve for loss and loss expense in the consolidated balance sheets also included $ 66 million, $ 75 million and $ 64 million, at December 31, 2024, 2023 and 2022, respectively, for certain life and health loss and loss expense reserves. Additional disclosures for reserves related to these health claims are not material and therefore not provided.

 We experienced $ 236 million of favorable development on prior accident years including $ 138 million of favorable development in commercial lines, $ 26 million of favorable development in personal lines and $ 8 million of unfavorable development in excess and surplus lines during 2024. Within commercial lines, we recognized favorable development of $ 83 million for the workers' compensation line and $ 74 million for the commercial property line due to reduced uncertainty of prior accident year loss and loss expense for these lines. This was partially offset by unfavorable development of $ 26 million for the commercial casualty line. Within personal lines, we recognized favorable reserve development of $ 54 million for the homeowner line of business and unfavorable reserve development of $ 20 million in personal auto.

 We experienced $ 215 million of favorable development on prior accident years including $ 123 million of favorable development in commercial lines, $ 64 million of favorable development in personal lines and $ 11 million of favorable development in excess and surplus lines during 2023. Within commercial lines, we recognized favorable development of $ 66 million for the workers' compensation line and $ 55 million for the commercial property line due to reduced uncertainty of prior accident year loss and loss expense for these lines. This was partially offset by unfavorable development of $ 15 million for the commercial casualty line. Within personal lines, we recognized favorable reserve development of $ 53 million for the homeowner line of business and $ 15 million in personal auto.

 We experienced $ 159 million of favorable development on prior accident years including $ 76 million of favorable development in commercial lines, $ 61 million of favorable development in personal lines and $ 9 million of favorable development in excess and surplus lines during 2022. Within commercial lines, we recognized favorable development of $ 63 million for the workers' compensation line and $ 44 million for the commercial property line due to reduced uncertainty of prior accident year loss and loss expense for these lines. This was partially offset by unfavorable development of $ 25 million for the commercial casualty line and $ 23 million for the commercial auto line. Within personal lines, we recognized favorable reserve development of $ 54 million for the homeowner line of business.

 Included in our lines of business are asbestos and environmental claims. We carried $ 119 million and $ 98 million of net loss and loss expense reserves for asbestos and environmental claims at December 31, 2024 and 2023, respectively. The asbestos and environmental claims amounts for each respective year constituted less than 2.0 % of total net loss and loss expense reserves at these year-end dates. We believe our exposure to asbestos and environmental claims is limited, largely because our reinsurance retention was $ 500,000 or below prior to 1987. We also were predominantly a personal lines company in the 1960s and 1970s. During the 1980s and early 1990s, commercial lines grew as a percentage of our overall business and our exposure to asbestos and environmental claims grew accordingly. Over that period, we included an asbestos and environmental exclusion in almost all policies or endorsed the exclusion to the policies. We have no exposure to asbestos and environmental claims related to our acquisition of Cincinnati Global. We continue to monitor our claims for evidence of material exposure to other mass tort classes but have found no such credible evidence to date.

 For all lines of business, the claim counts reported are primarily measured by insurance coverages that are triggered when a loss occurs and a reserve is established. For this purpose, coverages are defined as unique combinations of certain attributes such as line of business and cause of loss. Claims that are opened and closed without payment are included in the reported claim counts. Claim counts are presented on a direct basis only and do not reflect any assumed or ceded reinsurance.

 In the following tables, commercial casualty, workers' compensation and excess and surplus lines each disclose 10 accident years of loss and ALAE reserves and the cumulative number of reported claims. Commercial auto, commercial property, personal auto and homeowner each disclose five accident years of loss and ALAE reserves and the cumulative number of reported claims consistent with the number of years for which claims incurred typically remain outstanding.

 NOTE 6 – Deferred Policy Acquisition Costs
 Expenses directly related to successfully acquired insurance policies – primarily commissions, premium taxes and underwriting costs – are deferred and amortized over the terms of the policies. We update our acquisition cost assumptions periodically to reflect actual experience. For property casualty, we evaluate the costs for recoverability. No premium deficiencies were recorded in the consolidated statements of income in 2024, 2023 and 2022, as the sum of the anticipated loss and loss expenses, policyholder dividends and unamortized deferred acquisition expenses did not exceed the related unearned premiums and anticipated investment income.

 NOTE 7 – Note Payable
 We have one unsecured revolving credit facility through multiple commercial banks that expires on February 4, 2026. The borrowing capacity is $ 300 million with an additional $ 300 million accordion feature. Terms and conditions of the agreement include a debt-to-total capital maximum of 35 %. We had no compensating balance requirements on short-term debt for either 2024 or 2023. The line of credit had $ 25 million drawn at both December 31, 2024 and 2023. The interest rate charged on our borrowings on this credit agreement ranged from 5.56 % to 6.34 % during 2024 and ranged from 5.27 % to 6.33 % during 2023. In addition, we have letters of credit related to our Cincinnati Re operations with no amounts drawn at December 31, 2024 and 2023. On September 12, 2024, we terminated our $ 94 million unsecured letter of credit agreement, which provided a portion of the capital needed to support Cincinnati Global's obligations at Lloyd's, and replaced the letter of credit agreement with common equities held in Lloyd's trust accounts. No amount was drawn on the unsecured letter of credit agreement at December 31, 2023.

 NOTE 9 – Shareholders' Equity and Dividend Restrictions
 Declared cash dividends per share were $ 3.24, $ 3.00 and $ 2.76 for the years ended December 31, 2024, 2023 and 2022, respectively.

 Our lead insurance subsidiary, The Cincinnati Insurance Company, paid dividends to the parent company of $ 290 million, $ 526 million and $ 729 million in 2024, 2023 and 2022, respectively. State regulatory requirements restrict the dividends insurance subsidiaries can pay. Generally, the most our lead insurance subsidiary can pay without prior regulatory approval is the greater of 10 % of statutory capital and surplus or 100 % of statutory net income for the prior calendar year. Dividends exceeding these limitations may be paid only with approval of the insurance department of the domiciliary state. During 2025, the total that our lead insurance subsidiary may pay in dividends is approximately $ 1.245 billion.

 Dividend payments from Cincinnati Global to the parent company are subject to regulation by U.K. law. Cincinnati Global paid no dividends to the parent company in 2024, 2023 or 2022.

 NOTE 10 – Reinsurance
 Primary components of our property casualty reinsurance assumed operations include involuntary and voluntary assumed as well as contracts from our reinsurance assumed operations, known as Cincinnati Re. Primary components of our ceded reinsurance include a property per risk treaty, property excess treaty, casualty per occurrence treaty, casualty excess treaty, property catastrophe treaty and retrocessions on our reinsurance assumed operations. Management's decisions about the appropriate level of risk retention are affected by various factors, including changes in our underwriting practices, capacity to retain risks and reinsurance market conditions.

 Deferred tax assets and liabilities reflect temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amount recognized for tax purposes.

 Deferred tax assets are reduced by a valuation allowance when management believes it is more likely than not that some, or all, of the deferred tax assets will not be realized. After considering all positive and negative evidence of taxable income in the carryback and carryforward periods as permitted by law, we believe it is more likely than not that all of the deferred tax assets on our U.S. domestic operations will be realized. As a result, we have no valuation allowance at December 31, 2024 and 2023, for our U.S. domestic operations.

 For financial reporting purposes, income (loss) before income taxes includes the following components:

 The provision (benefit) for federal income taxes is based upon the filing of a consolidated income tax return for the company and its domestic subsidiaries within the United States. We had no operating or capital loss carryforwards in the United States at December 31, 2024 and 2023. As more fully discussed below, Cincinnati Global, has operating loss carryforwards in the United Kingdom.

 Unrecognized Tax Benefits
 During 2022, we received favorable guidance from the Internal Revenue Service (IRS) supporting our tax position related to our unrecognized tax benefit set up in 2018. As a result of this guidance, we released our $ 34 million gross unrecognized tax benefit liability at December 31, 2022. The $ 34 million release was recognized as an additional income tax benefit and is shown separately in our effective income tax rate reconciliation. We had no unrecognized tax benefit at December 31, 2024 or 2023.

 During the third quarter of 2024, we were notified by the IRS that the audit of tax years ended December 31, 2021 and 2020, has concluded. Despite the closure, the statute of limitations remains open through September 2025 for these two tax years. The statute of limitations is closed for tax years ended December 31, 2019 and earlier and is open for tax years ended December 31, 2022 and later.

 In addition to our IRS filings, we file income tax returns with immaterial amounts in various state jurisdictions and record these amounts in our provision for income taxes for both current and deferred taxes. The statute of limitations for state income tax purposes has closed for tax years ended December 31, 2020 and earlier.

 Cincinnati Global operates in the United Kingdom and as such, is subject to tax in that jurisdiction. The statute of limitations for tax return review by His Majesty's Revenue and Customs (HMRC) has closed for tax returns with a submission deadline ended December 31, 2022, and earlier. There are currently no tax returns under review by HMRC.

 Income taxes paid in our consolidated statements of cash flows are shown net of refunds received. We received no refund in 2024, a $ 2 million refund in 2023 and no refund in 2022.

 Deferred tax assets are reduced by a valuation allowance when management believes it is more likely than not that some, or all, of the deferred tax assets will not be realized. After considering all positive and negative evidence of taxable income in the carryback and carryforward periods as permitted by law, we believe it is more likely than not that all of the deferred tax assets of Cincinnati Global will be realized. As a result, we had no valuation allowance at December 31, 2024 or 2023. We had a valuation allowance of $ 31 million at December 31, 2022.

 The following is a tabular reconciliation of the total amounts of our Cincinnati Global valuation allowance:

 Cincinnati Global had no operating loss carryforwards in the United States and $ 78 million in the United Kingdom at December 31, 2024, and none in the United States and $ 100 million in the United Kingdom at December 31, 2023. These Cincinnati Global losses can only be utilized within the Cincinnati Global group in both the United States and in the United Kingdom and cannot offset the income of our domestic operations in the United States.

 The sources of dilution of our common shares are certain equity-based awards as discussed in Note 17, Share-Based Associate Compensation Plans. The above table includes the number of anti-dilutive share-based awards at year-end 2024, 2023 and 2022. In accordance with Accounting Standards Codification 260, Earnings per Share, the assumed exercise of share-based awards were excluded from the computation of diluted loss per share for the year-ended 2022, because their exercise would have anti-dilutive effects.

 NOTE 13 – Employee Retirement Benefits
 We sponsor a qualified defined benefit pension plan that we closed entry into for new associates as of June 30, 2008, and only participants 40 years of age or older as of August 31, 2008, could elect to continue to participate. During 2008, we changed the form of retirement benefit we offer some associates to a company match on contributions to a 401(k) plan as further explained below. For participants remaining in the pension plan, we continue to fund future benefit obligations. Benefits for the defined benefit pension plan are based on years of credited service and compensation level. Contributions are based on the prescribed method defined in the Pension Protection Act. Our net periodic benefit cost is based on certain actuarial assumptions and also is composed of several components that are determined using the projected unit credit actuarial cost method. The qualified plan has been amended to allow for distribution of vested balances to terminated participants.

 We sponsor a defined contribution plan (401(k) plan) for eligible associates with matching company contributions totaling $ 29 million, $ 26 million and $ 24 million during the years 2024, 2023 and 2022, respectively. Associates who are not accruing benefits under the pension plan are eligible to receive the company match of up to 6 % of cash compensation. Participants vest in the company match for the 401(k) plan after three years of eligible service.

 We maintain a supplemental executive retirement plan (SERP) with a benefit obligation of $ 13 million at
 year-end 2024 and $ 11 million at year-end 2023, which is included in the projected benefit obligation. The company also makes available to a select group of associates the CFC Top Hat Savings Plan, a nonqualified deferred compensation plan, which had a fair value of $ 87 million and $ 67 million at December 31, 2024 and 2023, respectively. Company matching contributions to the CFC Top Hat Savings Plan totaled approximately $ 1 million for the years 2024, 2023 and 2022, respectively.

 Defined Benefit Pension Plan Assumptions
 We evaluate our pension plan assumptions annually and update them as necessary. This is a summary of the weighted-average assumptions used to determine our benefit obligations at December 31 for the plans:

 To determine the discount rate for each plan, a theoretical settlement portfolio of high-quality rated corporate bonds was chosen to provide payments approximately matching the plan's projected benefit payments. A single interest rate for each plan was determined resulting in a discounted value of the plan's benefit payments that equates to the market value of the selected bonds. The discount rate is reflective of current market interest rate conditions and our plan's liability characteristics. Based on this analysis, we increased the rate from the prior year by 0.64 percentage points for the qualified pension plan and by 0.55 percentage points for the SERP. Compensation increase assumptions reflect anticipated rates of inflation, real return on wage growth and merit and promotional increases. The mortality assumption is updated annually to reflect the updated mortality scales. The Pri-2012 tables with Scale MP-2021 was used for the years 2024, 2023 and 2022.

 This is a summary of the weighted-average assumptions used to determine our net periodic benefit cost for the plans:

 The discount rate was decreased by 0.30 percentage points for the qualified pension plan and 0.31 percentage points for the SERP due to market interest rate conditions at the beginning of 2024. The discount rate assumptions for our benefit obligation generally track with high-quality rated corporate bond yields chosen in our theoretical settlement portfolio, and yearly adjustments reflect any changes to those bond yields. We believe the expected
 Cincinnati Financial Corporation - 2024 10-K - Page 167

 return on plan assets is representative of the expected long-term rate of return on these assets, which is consistent with 2024 expectations of interest rates and based partially on the fact that the plan's common stock holdings pay dividends. We review historical actual return on plan assets when determining our expected long-term rate of return. Total portfolio return for 2024 was 18.7 % and for 2023 was 11.8 %. Our compensation increase assumptions in 2024 reflect anticipated rates of inflation, real return on wage growth and merit and promotional increases.

 The 2024 change in the amount recognized in other comprehensive income from 2023 is largely due to higher year over year return on plan assets and increases in actuarial gain resulting from increases in discount rates.

 Service costs and non-service costs (benefit) are allocated in the same proportion primarily to underwriting, acquisition and insurance expenses line item with the remainder allocated to the insurance losses and contract holders' benefits line item on the consolidated statements of income for 2024, 2023 and 2022.

 Defined Benefit Pension Plan Assets
 The pension plan assets are managed to maximize total return over the long term while providing sufficient liquidity and current return to satisfy the cash flow requirements of the plan. The plan's day-to-day investment decisions are managed by our internal investment department; however, overall investment strategies are discussed with our employee benefits committee. Our investment strategy is to weight our portfolio towards large-cap, high-quality, dividend-growing equities that we have historically favored. As our plan matures and interest rates normalize, we expect a greater allocation to fixed-income securities to better align asset and liability market risks. Our fixed-maturity bond portfolio is investment grade. The plan does not engage in derivative transactions.

 Including cash, during 2024 we held approximately 83 % of our pension portfolio in domestic common equity investments. The remainder of the portfolio consisted of 10 % percent in cash, 4 % in United States
 Cincinnati Financial Corporation - 2024 10-K - Page 169

 government fixed-maturity investments, 2 % in domestic corporate fixed-maturity investments, and 1 % in states, municipalities and taxable political subdivisions fixed-maturity investments. Our common equity portfolio consisted of 31 % in the information technology sector, 20 % in the financial sector, 17 % in the industrials sector, and 12 % in the healthcare sector, at year-end 2024. No additional sectors accounted for 10 % or more of our common equity portfolio balance at year-end 2024.

 Investments in securities are valued based on the fair value hierarchy outlined in Note 3, Fair Value Measurements. The pension plan did not have any liabilities carried at fair value during the years ended December 31, 2024 and 2023. The following table shows the fair value hierarchy for those assets measured at fair value on a recurring basis at December 31, 2024 and 2023. Excluded from the table below is cash on hand of $ 36 million and $ 16 million at December 31, 2024 and 2023, respectively.

 Our pension plan assets included 100,610 shares of the company's common stock, which had a fair value of $ 14 million and $ 10 million at December 31, 2024 and 2023, respectively. The defined benefit pension plan did not purchase or sell any of our common stock during 2024 or 2023. The company paid less than $ 1 million in both 2024 and 2023 in cash dividends on our common stock to the pension plan.

 We estimate $ 8 million of benefit payments from the SERP during 2025. We expect to make the following benefit payments for our qualified plan and SERP, reflecting expected future service:

 NOTE 14 – Statutory Accounting Information
 Insurance companies' statutory financial statements are presented on the basis of accounting practices prescribed or permitted by applicable state insurance departments of domicile. Insurance companies use statutory accounting practices (SAP) as recognized by various states. We have adopted the National Association of Insurance Commissioners' (NAIC) Accounting Practices and Procedures manual, version effective January 1, 2001, and updates through the current year as a component of prescribed or permitted practices by laws of the state of domicile. The primary differences between SAP and GAAP include the valuation of investment gains and losses, expensing of policy acquisition costs, actuarial assumptions for life insurance reserves and deferred income taxes based on differences in statutory and taxable income.

 Statutory net income and capital and surplus are determined in accordance with SAP prescribed or permitted by insurance regulatory authorities for five legal entities, our lead insurance subsidiary and its four insurance subsidiaries. Statutory capital and surplus for our insurance subsidiary, The Cincinnati Insurance Company, includes capital and surplus of its four insurance subsidiaries. All capital and surplus amounts exceed statutory risk-based capital requirements. The statutory net income and statutory capital and surplus are presented below:

 Cincinnati Financial Corporation - 2024 10-K - Page 171

 NOTE 16 – Commitments and Contingent Liabilities
 The company, through its insurance subsidiaries, is involved in claims litigation arising in the ordinary course of conducting its business, both as a liability insurer defending or providing indemnity for third-party claims brought against insureds and as an insurer defending coverage claims brought against it. The company accounts for such activity through the establishment of unpaid loss and loss expense reserves. Subject to the uncertainties discussed in Note 4, Property Casualty Loss and Loss Expenses, and in the discussion in the balance of this Note, we believe that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses, costs of defense, and reinsurance recoveries, is immaterial to our consolidated financial position, results of operations and cash flows.

 The company and its subsidiaries also are occasionally involved in other legal and regulatory proceedings, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of state or national classes. Such proceedings have alleged, for example, improper depreciation of labor costs in repair estimates. The company's insurance subsidiaries also are occasionally parties to individual actions in which extra-contractual damages, punitive damages or penalties are sought, such as claims alleging bad faith handling of insurance claims or writing unauthorized coverage or claims alleging discrimination by former or current associates.

 On a quarterly basis, we review these outstanding matters. Under current accounting guidance, we establish accruals when it is probable that a covered loss has been incurred and we can reasonably estimate its potential exposure. The company accounts for such probable and estimable losses, if any, through the establishment of legal expense reserves. Based on our quarterly review, we believe that our accruals for probable and estimable losses are reasonable and that the amounts accrued do not have a material effect on our consolidated financial position, results of operations and cash flows. However, if any one or more of these matters results in a judgment against us or settlement for an amount that is significantly greater than the amount accrued, the resulting liability could have a material effect on the company's consolidated financial position, results of operations and cash flows. Based on our most recent review, our estimate for any other matters for which the risk of loss is not probable, but more than remote, is immaterial.

 NOTE 17 – Share-Based Associate Compensation Plans
 Four equity compensation plans currently permit us to grant various types of equity awards. We currently grant incentive stock options, nonqualified stock options, service-based restricted stock units and performance-based restricted stock units to associates, including some with market-based performance objectives under our shareholder-approved plans. We also have a Holiday Stock Plan that permits annual awards of one share of common stock to each full-time associate for each full calendar year of service up to a maximum of 10 shares. One of our equity compensation plans permits us to grant stock to our outside directors as a component of their annual compensation. We used treasury shares for share-based compensation award issues or exercises during 2024 and 2023.

 Share-based compensation cost after tax was $ 37 million, $ 32 million and $ 29 million for the years ended
 December 31, 2024, 2023 and 2022, respectively. The related income tax benefit recognized was $ 9 million,$ 8 million and $ 7 million for the years ended December 31, 2024, 2023 and 2022, respectively. Options exercised during the years ended December 31, 2024, 2023 and 2022, had intrinsic value of $ 32 million, $ 14 million and $ 21 million, respectively. Intrinsic value is the market price less the exercise price. Options vested during the years ended December 31, 2024 and 2022 had total intrinsic value of $ 12 million and $ 2 million, respectively. Options vested during the year ended December 31, 2023 had no intrinsic value because the weighted average exercise price was greater than the market price on the reporting date.

 As of December 31, 2024, we had $ 44 million of unrecognized total compensation cost related to nonvested stock options and restricted stock unit awards. That cost will be recognized over a weighted-average period of 1.7 years.

 Stock Options
 Stock options are granted to associates at an exercise price equal to the fair value as determined by the average high and low sales price reported on the Nasdaq Global Select Market for the grant date and are exercisable over 10 -year periods. The stock options generally vest ratably over a three -year period. In determining the share-based compensation amounts, we estimate the fair value of each option granted on the date of grant using the Black Scholes pricing model. We make the following assumptions to develop the Black Scholes pricing model as follows:
 • Weighted-average expected term is based on historical experience of similar awards with consideration for current exercise trends.
 • Expected volatility is based on our stock price over a historical period that approximates the expected term.
 • Dividend yield is determined by dividing the annualized per share dividend by the stock price on the date of grant.
 • Risk-free rates are the implied yield currently available on zero-coupon U.S. Treasury issues with a remaining term approximating the expected term.

 The following weighted average assumptions were used in determining fair value for option grants issued:

 Cash received from the exercise of options was $ 10 million, $ 9 million and $ 10 million for the years ended December 31, 2024, 2023 and 2022, respectively. We acquired 259,224, 72,549 and 80,538 shares totaling
 $ 33 million, $ 8 million and $ 10 million, respectively, from associates in consideration for option exercises during 2024, 2023 and 2022. The weighted-average remaining contractual life for options expected to vest as of December 31, 2024, was 8.54 years.

 Under all active shareholder approved plans, a total of 19.3 million shares were authorized to be granted. At December 31, 2024, 11.4 million shares remained available for future issuance under the plans. During 2024, we granted 9,779 shares of common stock to our directors for 2023 board service fees.

 Restricted Stock Units
 Service-based restricted stock units granted to associates are valued at fair value of the shares on the date of grant less the present value of the dividends that holders of restricted stock units do not receive on the shares underlying the restricted stock units during the vesting period. Service-based restricted stock units generally cliff vest three years after the date of grant. We also grant restricted stock units which vest on a three year ratable vesting schedule. Service-based restricted stock units vested during the year had an intrinsic value of $ 23 million, $ 22 million and $ 32 million for the years ended December 31, 2024, 2023 and 2022, respectively.

 We have performance-based awards that vest on the first day of March after a three -calendar-year performance period. These awards vest according to the level of three -year total shareholder return achieved compared with a peer group over a three -year performance period with payouts ranging from 0 % to 200 % for awards granted in 2024, 2023 and 2022. Three -year total shareholder return is calculated by using annualized total return of a stock to an investor due to capital gain appreciation plus reinvestment of all dividends.

 For the three-year performance period ended December 31, 2024, our total shareholder return exceeded three of our nine peers. We expect 30 % payout of these shares to occur in March 2025. During 2024 and 2023, no shares of performance-based restricted stock units were issued for the three-year performance period ended December 31, 2023 and 2022, as our total shareholder return exceeded two of eight peers in our 2021 peer group and one of eight peers in our 2020 peer group. Performance-based awards vested during the year end December 31, 2022 had an intrinsic value of $ 6 million.

 These performance-based awards are valued using a Monte-Carlo valuation on the date of grant, which uses a risk-neutral framework to model future stock price movements based upon the risk-free rate of return, the volatility of each peer and the pairwise correlations of each peer being modeled. Compensation cost is recognized regardless of whether the market-based performance objective has been satisfied. We make assumptions to develop the Monte-Carlo model as follows:
 • Correlation coefficients are based upon the stock price data used to calculate the historical volatilities. The correlation coefficients are used to model the way the price of each entity's stock tends to move in relation to each other.
 • Expected volatility is based on each company's historical volatility using daily stock price observations with the period commensurate with the performance measurement period.
 Cincinnati Financial Corporation - 2024 10-K - Page 174

 • Dividend yield assumption is based on our current expected annual cash dividend and the valuation date stock price.
 • Risk-free rates are equal to the yield, as of the measurement date, of the zero-coupon U.S. Treasury bill that is commensurate with the performance measurement period.

 NOTE 18 – Segment Information
 We operate primarily in two industries, property casualty insurance and life insurance. Our CODM is the chief executive officer who regularly reviews our reporting segments to make decisions about allocating resources and assessing performance. Our reporting segments are:
 • Commercial lines insurance
 • Personal lines insurance
 • Excess and surplus lines insurance
 • Life insurance
 • Investments

 We report as Other the noninvestment operations of the parent company and its noninsurer subsidiary, CFC Investment Company. We also report as Other the underwriting results of Cincinnati Re and Cincinnati Global.

 Revenues come primarily from unaffiliated customers:
 • All four insurance segments record revenues from insurance premiums earned.
 • Fee revenues for the commercial, personal and excess and surplus insurance segments primarily represent installment fees. Fee revenues for the life insurance segment represent separate account investment management fees.
 • Our investments' revenues consist of pretax net investment income and investment gains and losses.
 • Other revenues are primarily finance income and earned premiums of Cincinnati Re and Cincinnati Global.

 Income or loss before income taxes for each segment are reported based on the nature of that business area's operations:
 • Income or loss before income taxes for the insurance segments is defined as underwriting profit or loss.
 For commercial lines, personal lines and excess and surplus lines insurance segments, we calculate underwriting profit or loss as premiums earned and fee revenue minus loss and loss expenses and underwriting expenses incurred.
 For the life insurance segment, we calculate underwriting profit or loss as premiums earned and fee revenue, minus contract holders' benefits and expenses incurred, plus investment interest credited to contract holders.
 • Income or loss before income taxes for the investments segment is net investment income plus investment gains and losses for investments of the entire company, minus investment interest credited to contract holders of the life insurance segment.
 • Income or loss before income taxes for the Other category is primarily due to Cincinnati Re and Cincinnati Global premiums earned minus loss and loss expenses and underwriting expenses incurred. It also includes interest expense from debt of the parent company as well as operating expenses of our headquarters.

 For all segments, the CODM uses income or loss before income taxes, and its components, to allocate resources (including associate, financial and capital resources) primarily during the annual budgeting and forecasting process and throughout the year as necessary. For the commercial lines, personal lines, excess and surplus and life segments, the CODM uses this metric to assess performance by analyzing the relationship between premium revenue and loss and loss expenses and underwriting expenses. As part of this analysis, the drivers and components of those revenue and expense items, such as pricing, exposure growth and inflation, are also considered as necessary. For the investments segment, the CODM considers overall investment performance as well as current conditions to invest available cash flow in both fixed-maturity and equity securities in a manner that balances current income needs with longer-term investment growth goals.

 We do not separately report the identifiable assets of property casualty insurance for the commercial, personal and excess and surplus lines segments or for Cincinnati Re because we do not use that measure to analyze performance. We include all investment portfolio assets, regardless of ownership, in the investments segment.

 ITEM 9. Changes in and Disagreements With Accountants on
 Accounting and Financial Disclosure
 We had no disagreements with the independent registered public accounting firm on accounting and financial disclosure during the last two fiscal years.

 ITEM 9A. Controls and Procedures
 Evaluation of Disclosure Controls and Procedures – The company maintains disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act)).

 Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. The company's management, with the participation of the company's chief executive officer and chief financial officer, has evaluated the effectiveness of the design and operation of the company's disclosure controls and procedures as of December 31, 2024. Based upon that evaluation, the company's chief executive officer and chief financial officer concluded that the design and operation of the company's disclosure controls and procedures provided reasonable assurance that the disclosure controls and procedures are effective to ensure that:
 • information required to be disclosed in the company's reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and
 • such information is accumulated and communicated to the company's management, including its chief executive officer and chief financial officer, as appropriate, to allow for timely decisions regarding required disclosures.

 Changes in Internal Control over Financial Reporting – During the three months ended December 31, 2024, there were no changes in our internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We are continually monitoring and assessing any potential impact on the design and operating effectiveness of our internal controls over financial reporting related to the alternating of associate schedules between working at our headquarters and working from remote locations. Management's Annual Report on Internal Control Over Financial Reporting and the Report of the Independent Registered Public Accounting Firm are set forth in Item 8.

 ITEM 9B. Other Information
 Neither the company nor any of our officers or directors adopted or terminated a Rule 10b5-1 or non-Rule 10b5-1 trading arrangement as defined by Item 408(a) and Item 408(d) of Regulation S-K during the last fiscal quarter.

 ITEM 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections
 This item is not applicable to the company.
