 As of December 31, 2023, we had one loan totaling $96.0 million which bore interest at a floating rate. The variable interest rate payments are based on SOFR plus 1.60% and a 10 basis point spread adjustment which reflects our new interest rates under our 2022 Facility. The information in the table above reflects our projected interest rate obligations for the floating rate payments based on one-month SOFR as of December 31, 2023, of 5.40%.
On December 26, 2021, the Board of Trustees of Pillarstone REIT adopted a new rights agreement (the "Pillarstone Rights Agreement"), pursuant to which each holder of Pillarstone REIT common stock received one preferred share purchase right (a "Right") per common share held as of the applicable record date. Each Right entitles the registered holder to purchase from Pillarstone REIT one one-thousandth (a "Unit") of a series D preferred share of Pillarstone at a purchase price ("Purchase Price") of $7.00 per Unit, subject to adjustment. The Rights are exercisable upon the occurrence of certain events as described in the Pillarstone Rights Agreement, including the acquisition by certain holders of 5% or more of the common shares of Pillarstone REIT (an "Acquiring Person"). Upon the acquisition of Pillarstone REIT common shares by an Acquiring Person, each holder of a Right (other than an Acquiring Person), will have the right to receive upon exercise a number of Pillarstone REIT common shares having a market value of two times the Purchase Price. As set forth in the Amended and Restated Limited Partnership Agreement of Pillarstone OP, dated as of December 8, 2016 (the "Pillarstone Partnership Agreement"), we have the contractual right to have our limited partnership interests in Pillarstone redeemed at our discretion. However, upon receipt of a redemption notice, Pillarstone OP has the option of the applicable redemption price in cash, based on the market value of Pillarstone REIT common shares, or in Pillarstone REIT common shares. To the extent we seek to have our partnership units in Pillarstone OP redeemed and Pillarstone OP elects to pay the applicable redemption price in Pillarstone REIT common shares (and such shares represent 5% or more of the outstanding common shares of Pillarstone REIT), the Rights could become exercisable. To the extent the Rights are exercised as a result of our Pillarstone OP units being redeemed for Pillarstone REIT common shares, our ownership interest in Pillarstone REIT would be significantly diluted, which could adversely impact the value of our investment in Pillarstone OP. Because the Pillarstone Rights Agreement seeks to prevent Whitestone OP from exercising its contractual Redemption Right, on July 12, 2022, Whitestone OP filed suit against Pillarstone REIT in the Court of Chancery of the State of Delaware challenging the Pillarstone Rights Agreement due to Pillarstone REIT's breach of the Pillarstone OP partnership agreement, breach of its fiduciary duty as general partner of Pillarstone OP to Whitestone OP, and breach of the implied covenant of good faith and fair dealing under the Pillarstone OP partnership agreement. The lawsuit seeks rescission and voiding of the Pillarstone Rights Agreement; a declaration that the Pillarstone Rights Agreement is unenforceable, invalid, and of no force and effect; an order permanently enjoining enforcement of the Pillarstone Rights Agreement; an award of monetary damages; and broad restrictions on Pillarstone REIT's ability to conduct its business, including buying properties, enforcing the Rights Agreement, incurring expenses, or engaging in transactions. On September 8, 2022, the Company's Motion to Preserve the Status Quo was granted by the Court, limiting Pillarstone from engaging in any acts outside the ordinary course of business and otherwise imposing restrictions on Pillarstone to ensure that Whitestone's right of redemption right is not impaired while the underlying dispute is being considered by the Court. Trial was held on July 17-18, 2023, and the post-trial briefing was held on October 18, 2023. Whitestone OP asked the Court to declare the Pillarstone Rights Agreement unenforceable and to permit Whitestone OP to tender a Notice of Redemption. In addition (or alternatively), Whitestone OP sought an award of monetary damages of at least $51,200,600 based on the amount that Pillarstone's misconduct precluded Whitestone OP from receiving in or around December 2021, as well as an award of pre- and post-judgment interest at the statutory rate. On January 25, 2024, the Delaware Court of Chancery held that Pillarstone breached the implied covenant of good faith and fair dealing when it adopted shareholder rights plan (the "Rights Plan") that effectively thwarted Whitestone OP from exercising the unfettered contractual redemption right it obtained in connection with its investment in the partnership and the Court held that the Rights Plan was unenforceable as to the limited partner and allowed Whitestone OP to exercise its redemption right. On January 25, 2024, the Company exercised its notice of redemption for substantially all of its investment in the partnership. While we do not believe the overall impact of the Pillarstone Rights Agreement on the carrying value of our investment in Pillarstone OP is material, we cannot reasonably estimate a range of possible loss at this time. These amounts do not reflect future rental revenues from the renewal or replacement of existing leases and exclude reimbursements of operating expenses and rental increases that are not fixed.

 Forward-Looking Statements

 The following discussion should be read in conjunction with our audited consolidated financial statements and the notes thereto in this Annual Report on Form 10-K.

 This Annual Report on Form 10-K contains forward-looking statements within the meaning of the federal securities laws, including discussion and analysis of our financial condition, anticipated capital expenditures required to complete projects, amounts of anticipated cash distributions to our shareholders in the future and other matters. These forward-looking statements are not historical facts but reflect the intent, belief or current expectations of our management based on its knowledge and understanding of our business and industry. Forward-looking statements are typically identified by the use of terms such as "may," "will," "should," "potential," "predicts," "anticipates," "expects," "intends," "plans," "believes," "seeks," "estimates" or the negative of such terms and variations of these words and similar expressions, although not all forward-looking statements include these words. These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control, are difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements.

 Forward-looking statements that were true at the time made may ultimately prove to be incorrect or false. You are cautioned not to place undue reliance on forward-looking statements, which reflect our management's view only as of the date of this Annual Report on Form 10-K. We undertake no obligation to update or revise forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes to future operating results. Factors that could cause actual results to differ materially from any forward-looking statements made in this Annual Report on Form 10-K include:

 •

 the imposition of federal income taxes if we fail to qualify as a real estate investment trust ("REIT") in any taxable year or forego an opportunity to ensure REIT status;

 •

 uncertainties related to the national economy and the real estate industry, both in general and in our specific markets;

 •

 legislative or regulatory changes, including changes to laws governing REITs;

 •

 adverse economic or real estate developments or conditions in Texas or Arizona, Houston and Phoenix in particular, including the potential impact of public health emergencies such as COVID-19 on our tenants' ability to pay their rent, which could result in bad debt allowances or straight-line rent reserve adjustments;

 •

 our current geographic concentration in the Houston and Phoenix metropolitan area makes us susceptible to local economic downturns;

 •

 increases in interest rates, including as a result of inflation, which may increase our operating costs or general and administrative expenses

 •

 natural disasters, such as floods and hurricanes, which may increase as a result of climate change may adversely affect our returns and adversely impact our existing and prospective tenants;

 •

 increasing focus by stakeholders on environmental, social and governance matters;

 •

 financial institution disruptions;

 •

 availability and terms of capital and financing, both to fund our operations and to refinance our indebtedness as it matures;

 •

 decreases in rental rates or increases in vacancy rates;

 •

 harm to our reputation, ability to do business and results of operations as a result of improper conduct by our employees, agents or business partners;

 •

 litigation risks;

 •

 lease-up risks, including leasing risks arising from exclusivity and consent provisions in leases with significant tenants;

 •

 our inability to renew tenant leases or obtain new tenant leases upon the expiration of existing leases;

 •

 risks related to generative artificial intelligence tools and language models, along with the potential interpretations and conclusions they might make regarding our business and prospects, particularly concerning the spread of misinformation;

 •

 geopolitical conflicts, such as the ongoing conflict between Russia and Ukraine, the conflict in the Gaza Strip and unrest in the Middle East;

 •

 our inability to generate sufficient cash flows due to market conditions, competition, uninsured losses, changes in tax or other applicable laws;

 •

 the need to fund tenant improvements or other capital expenditures out of operating cash flow;

 •

 the risk that we are unable to raise capital for working capital, acquisitions or other uses on attractive terms or at all; and

 •

 the extent to which our estimates regarding Pillarstone OP's financial condition and results of operations differ from actual results.

 The forward-looking statements should be read in light of these factors and the factors identified in the "Risk Factors" section of this Annual Report on Form 10-K.

 Item 1. Business.

 General

 We are a Maryland REIT engaged in owning and operating commercial properties in culturally diverse markets in major metropolitan areas. We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the "Code").

 We are internally managed and, as of December 31, 2023, we wholly-owned a real estate portfolio of 55 properties that meet our Community Centered Property strategy containing approximately 5.0 million square feet of gross leasable area ("GLA"), located in Texas and Arizona. Our consolidated property portfolio has a gross book value of approximately $1.2 billion and book equity, including noncontrolling interests, of approximately $420 million as of December 31, 2023.

 Further, as of December 31, 2023, we, through our equity-method investment in Pillarstone Capital REIT Operating Partnership LP ("Pillarstone" or "Pillarstone OP"), owned a majority interest in eight properties that do not meet our Community Centered Property strategy containing approximately 0.9 million square feet of GLA (the "Pillarstone Properties"). We own 81.4% of the total outstanding units of Pillarstone OP, which we account for using the equity method. We also managed the day-to-day operations of Pillarstone OP pursuant to a management agreement, which was terminated on August 18, 2022. In this Annual Report on Form 10-K, unless otherwise indicated, we do not include the Pillarstone Properties when we refer to our properties.

 Our common shares of beneficial interest, par value $0.001 per share, are traded on the New York Stock Exchange (the "NYSE") under the ticker symbol "WSR." Our offices are located at 2600 South Gessner Road, Suite 500, Houston, Texas 77063. Our telephone number is (713) 827-9595 and we maintain a website at www.whitestonereit.com. The contents of our website are not incorporated into this filing.

 Our Strategy

 In October 2006, we adopted a strategic plan to acquire, redevelop, own and operate Community Centered Properties. We define Community Centered Properties as visibly located properties in established or developing culturally diverse neighborhoods in our target markets. We market, lease and manage our centers to match tenants with the shared needs of the surrounding neighborhood. Those needs may include specialty retail, grocery, restaurants, medical, educational, financial services, entertainment and experiences. Our goal is for each property to become a Whitestone-branded retail community that serves a neighboring five-mile radius around our property. We employ and develop a diverse group of associates who understand the needs of our multicultural communities and tenants.

 Our primary business objective is to increase shareholder value by acquiring, owning and operating Community Centered Properties. The key elements of our strategy include:

 •

 Strategically Acquiring Properties.

 Seeking High Growth Markets. We seek to strategically acquire commercial properties in high-growth markets. Our acquisition targets are located in densely populated, culturally diverse neighborhoods, primarily in and around Austin, Dallas-Fort Worth, Houston, Phoenix and San Antonio.

 Diversifying Geographically. Our current portfolio is concentrated in Houston and Phoenix. As of December 31, 2023, we wholly-owned 12 properties in Houston, nine properties in Dallas-Fort Worth, three properties in San Antonio, five properties in Austin and 26 properties in the Scottsdale and Phoenix, Arizona metropolitan areas.

 We believe that continued geographic diversification in markets where we have substantial knowledge and experience will help offset the economic risk from a single market concentration. We intend to continue to focus our expansion efforts on the Austin, Dallas-Fort Worth, Houston, Phoenix and San Antonio markets. We believe our management infrastructure and capacity can accommodate substantial growth in those markets. We may also pursue opportunities in other regions that are consistent with our Community Centered Property strategy. Markets in which we have developed some knowledge and contacts include Orlando, Florida and Denver, Colorado, both of which have economic, demographic and cultural profiles similar to our Arizona and Texas markets.

 Capitalizing on Availability of Reasonably Priced Acquisition Opportunities. We believe that currently and during the next several years there will continue to be excellent opportunities in our target markets to acquire quality properties at historically attractive prices. We intend to acquire assets in off-market transactions negotiated directly with owners or financial institutions holding foreclosed real estate and debt instruments that are either in default or on bank watch lists. Many of these assets may benefit from our Community Centered Property strategy and our management team's experience in turning around distressed properties, portfolios and companies. We have extensive relationships with community banks, attorneys, title companies and others in the real estate industry with whom we regularly work to identify properties for potential acquisition.

 •

 Redeveloping and Re-tenanting Existing Properties. We have substantial experience in repositioning underperforming properties and seek to add value through renovating and re-tenanting our properties to create Whitestone-branded Community Centered Properties. We seek to accomplish this by (1) stabilizing occupancy, with per property occupancy goals of 90% or higher; (2) adding leasable square footage to existing structures; (3) developing and building new leasable square footage on excess land; (4) upgrading and renovating existing structures; and (5) investing significant effort in recruiting tenants whose goods and services meet the needs of the surrounding neighborhood.

 •

 Recycling Capital for Greater Returns. We seek to continually upgrade our portfolio by opportunistically selling properties that do not have the potential to meet our Community Centered Property strategy and redeploying the sale proceeds into properties that better fit our strategy. Some of our properties that we own (the "non-core properties") may not fit our Community Centered Property strategy, and we may look for opportunities to dispose of these properties as we continue to execute our strategy.

 •

 Prudent Management of Capital Structure. Of our 55 properties, we currently have 50 properties that are unencumbered. We may seek to add mortgage indebtedness to existing and newly acquired unencumbered properties to provide additional capital for acquisitions. As a general policy, we intend to maintain a ratio of debt, net of cash, to undepreciated book value of real estate assets, including our proportional share of real estate from our unconsolidated real estate partnership, that is at or less than 60%. As of December 31, 2023, our ratio of debt, net of cash, to undepreciated book value of real estate assets was 50%.

 •

 Investing in People. We believe that our people are the heart of our culture, philosophy and strategy. We continually focus on developing associates who are self-disciplined and motivated and display, at all times, a high degree of character and competence. We provide them with equity incentives to align their interests with those of our shareholders.

 Our Structure

 Substantially all of our business is conducted through Whitestone REIT Operating Partnership, L.P., a Delaware limited partnership organized in 1998 (the "Operating Partnership"). We are the sole general partner of the Operating Partnership. As of December 31, 2023, we owned a 98.6% interest in the Operating Partnership.

 As of December 31, 2023, we wholly-owned a real estate portfolio consisting of 55 properties located in two states. The aggregate occupancy rate of our portfolio was 94% based on GLA as of December 31, 2023.

 We are hands-on owners who directly manage the operations and leasing of our properties. Substantially all of our revenues consist of base rents received under varying term leases. For the year ended December 31, 2023, our total revenues were approximately $147 million.

 Additionally, we, through our equity-method investment in Pillarstone, owned a majority interest in eight properties located in Dallas and Houston, Texas. The aggregate occupancy rate of the Pillarstone properties was approximately 54% based on GLA as of December 31, 2023.

 Our largest property, BLVD Place ("BLVD"), a retail community purchased on May 26, 2017 and located in Houston, Texas, accounted for 10.5% of our total revenues for the year ended December 31, 2023. BLVD also accounted for 15.9% of our consolidated real estate assets, net of accumulated depreciation, as of the year ended December 31, 2023.

 Competition

 All of our properties are located in areas that include competing properties. The amount of competition in a particular area could impact our ability to acquire additional real estate, sell current real estate, lease space and the amount of rent we are able to charge. We may be competing with owners, developers and operators, including, but not limited to, real estate investors, other REITs, insurance companies and pension funds.

 Should we decide to dispose of a property, we may compete with third-party sellers of similar types of commercial properties for suitable purchasers, which may result in our receiving lower net proceeds from a sale or in our not being able to dispose of such property at a time of our choosing due to the lack of an acceptable return. In operating and managing our properties, we compete for tenants based upon a number of factors including, but not limited to, location, rental rates, security, flexibility, expertise to design space to meet prospective tenants' needs and the manner in which the property is operated, maintained and marketed. We may be required to provide rent concessions, incur charges for tenant improvements and other inducements, or we may not be able to timely lease vacant space, all of which could adversely impact our results of operations.

 Many of our competitors have greater financial and other resources than us and also may have more operating experience. Generally, there are other neighborhood and community retail centers within relatively close proximity to each of our properties. There is, however, no dominant competitor in the Austin, Dallas-Fort Worth, Houston, Phoenix and San Antonio metropolitan areas. Our retail tenants also face increasing competition from outlet malls, internet retailers, catalog companies, direct mail and telemarketing.

 Compliance with Governmental Regulations

 Under various federal and state environmental laws and regulations, as an owner or operator of real estate, we may be required to investigate and clean up certain hazardous or toxic substances, asbestos-containing materials, or petroleum product releases at our properties. We may also be held liable to a governmental entity or to third parties for property damage and for investigation and cleanup costs incurred by those parties in connection with any such contamination. In addition, some environmental laws create a lien on a contaminated site in favor of the government for damages and costs the government incurs in connection with contamination on the site. The presence of contamination or the failure to remediate contamination at any of our properties may adversely affect our ability to sell or lease the properties or to borrow using the properties as collateral. We could also be liable under common law to third parties for damages and injuries resulting from environmental contamination coming from our properties.

 We will not purchase any property unless we are generally satisfied with the environmental status of the property. We typically obtain a Phase I environmental site assessment for each new acquisition, which includes a visual survey of the building and the property in an attempt to identify areas of potential environmental concerns, visually observing neighboring properties to assess surface conditions or activities that may have an adverse environmental impact on the property, and contacting local governmental agency personnel and performing a regulatory agency file search in an attempt to determine any known environmental concerns in the immediate vicinity of the property. A Phase I environmental site assessment does not include any sampling or testing of soil, groundwater or building materials from the property.

 We believe that our properties are in compliance in all material respects with all applicable federal, state and local laws and regulations regarding the handling, discharge and emission of hazardous or toxic substances. Because release of chlorinated solvents can occur as a result of dry cleaning operations, we participate in the Texas Commission on Environmental Quality Dry Cleaner Remediation Program ("DCRP") with respect to four of our properties that currently or previously had a dry cleaning facility as a tenant. The DCRP administers the Dry Cleaning Remediation fund to assist with remediation of contamination caused by dry cleaning solvents.

 We have not been notified by any governmental authority, and are not otherwise aware of any material noncompliance, liability or claim relating to hazardous or toxic substances in connection with any of our present or former properties. Nevertheless, it is possible that the environmental assessments conducted thus far and currently available to us do not reveal all potential environmental liabilities. It is also possible that subsequent investigations will identify material contamination or other adverse conditions, that adverse environmental conditions have arisen subsequent to the performance of the environmental assessments, or that there are material environmental liabilities of which management is unaware.

 Under the Americans with Disabilities Act ("ADA"), all places of public accommodation are required to meet certain federal requirements related to access and use by disabled persons. Our properties must comply with the ADA to the extent that they are considered "public accommodations" as defined by the ADA. The ADA may require removal of structural barriers to access by persons with disabilities in public areas of our properties where such removal is readily achievable. We believe that our properties are in substantial compliance with the ADA and that we will not be required to make substantial capital expenditures to address the requirements of the ADA. In addition, we will continue to assess our compliance with the ADA and to make alterations to our properties as required.

 Human Capital

 We believe that our people are the heart of our culture, philosophy and strategy. Our employees are in direct contact with our tenants and the communities we serve. We continually focus on developing associates who are self-disciplined and motivated and display at all times a high degree of character and competence. Employee engagement is critical to our long term success, so employees' performances are reviewed annually. Key employees are provided with equity incentives to align their interests with those of our shareholders. Every Whitestone associate is encouraged to be an owner.

 As of December 31, 2023, we had 79 employees, including 2 on leave.

 Diversity: We strive to create a culture of inclusivity and think of our shareholders, our tenants, and our communities as one. Every year, we hold diversity and sensitivity training for management and associates to reiterate the importance within our organization and to ensure that all associates practice this approach both internally and externally. We do not tolerate disrespectful or inappropriate behavior, unfair treatment, retaliation or harassment of any kind. In addition, pursuant to our bylaws, we seek to nominate trustees to the Board that represent a diversity of experience, gender, race, ethnicity and age. Though we have no formal policy addressing diversity, any individual who does not satisfy the qualifications above is not eligible for nomination or election as a trustee. This commitment to diversity applies across our Company.

 Employee Retention and Training: We conduct individual annual employee reviews that focus on goal setting as well as informal sessions with associates and executive team members. We created the Real Estate Executive Development program for associates that wish to continue their career and expand their knowledge of Whitestone REIT and real estate. Selected associates are chosen on an annual basis to participate in the program. In addition, for associates that wish to continue their education, whether it be receiving a Bachelors, MBA, or specialized certification, we will help to reimburse a portion of the fees for the program in accordance with Company policy. We also conduct a variety of trainings on an annual basis from OSHA and Safety Regulations to Anti-Harassment Training to ensure we are up-to-date on the most recent standards and regulations.

 Compensation and Benefits: We are committed to rewarding, supporting, and developing the associates who make it possible to deliver on our strategy. Our compensation package includes market-competitive pay, broad-based stock grants and bonuses, healthcare benefits, pension and retirement savings plans, among others. We also offer our team a variety of options for College Savings and 401(k) programs, including an employer 401(k) match up to 3.5%. There is a financial planner on site on a quarterly basis to help assist associates choose the best savings options.

 Health and Safety: The health and safety of our employees and their families is a top priority. We created an internal program that encourages associates to make healthy choices and lead a healthy lifestyle, including a gym reimbursement program.

 Environmental, Sustainability and Governance

 We believe that managing our environmental, sustainability and governance ("ESG") responsibilities is critical to creating and sustaining long-term value for our stakeholders. As part of our ESG initiatives, we have established an ESG Steering Committee, adopted a Sustainability Statement along with certain Environmental Policies, and prepared our 2023 ESG report. Our ESG efforts are supported by our ESG Steering Committee which helps us by setting our general ESG strategies, developing and implementing initiatives and policies, and monitoring and assessing developments related to improving our understanding of ESG matters.

 We seek to provide sustainable, high quality rental spaces with credit-worthy tenants, invest in our people to ensure we can attract and retain the talent we need to remain successful, and operate to the highest possible standards of ethics and transparency. Certain initiatives we have taken include installing electric vehicle charging stations at select centers, implementing green leases with our tenants, and onboarding software that allows us to track resource consumption and greenhouse gas emissions.

 Financial Information

 Additional financial information related to the Company is included in Item 8 "Financial Statements and Supplementary Data."

 Item 1A. Risk Factors.

 In addition to the other information contained in this Annual Report on Form 10-K, the following risk factors should be considered carefully in evaluating our business. Our business, financial condition, results of operations or the trading price of our common shares could be materially adversely affected by any of these risks. Please note that additional risks not presently known to us or which we currently consider immaterial may also impair our business and operations.

 Risks Associated with Real Estate

 Real estate property investments are illiquid due to a variety of factors and therefore we may not be able to dispose of properties when appropriate or on favorable terms.

 Our strategy includes opportunistically selling properties that do not have the potential to meet our Community Centered Property strategy. However, real estate property investments generally cannot be disposed of quickly. In addition, the Code imposes certain restrictions on the ability of a REIT to dispose of properties that are not applicable to other types of real estate companies. Therefore, we may not be able to vary our portfolio in response to economic or other conditions promptly or on favorable terms, which could cause us to incur extended losses, reduce our cash flows and adversely affect distributions to shareholders.

 We cannot predict whether we will be able to sell any property for the price or on the terms set by us or whether any price or other terms offered by a prospective purchaser would be acceptable to us, nor can we predict the length of time needed to find a willing purchaser and to close the sale of a property. To the extent we are unable to sell any properties for our book value, we may be required to take a non-cash impairment charge or loss on the sale, either of which would reduce our net income.

 We may be required to expend resources to correct defects or to make improvements before a property can be sold. There can be no assurance that we will have funds available to correct those defects or to make those improvements, which may impede our ability to sell a property. Further, we may agree to transfer restrictions that materially restrict us from selling a property for a period of time or impose other restrictions, such as a limitation on the amount of debt that can be placed or repaid on that property. These transfer restrictions could impede our ability to sell a property even if we deem it necessary or appropriate. These facts and any others that would further contribute to the illiquid character of real estate properties and impede our ability to respond to adverse changes in the performance of our properties may have a material adverse effect on our business, financial condition, results of operations, our ability to make distributions to our shareholders and the trading price of our common shares.

 Our business is dependent upon our tenants successfully operating their businesses, and their failure to do so could have a material adverse effect on our ability to successfully and profitably operate our business.

 We depend on our tenants to operate their businesses in a manner that generates revenues sufficient to allow them to meet their obligations to us, including their obligations to pay rent, maintain certain insurance coverage, pay real estate taxes and maintain the properties in a manner so as not to jeopardize their operating licenses or regulatory status. The ability of our tenants to fulfill their obligations under our leases may depend, in part, upon the overall profitability of their operations. A number of our tenants operate service and retail businesses that require in-person interactions with their customers to generate revenues. Public health emergencies such as the COVID-19 pandemic have affected customers' willingness to frequent some of our tenants' businesses, which has impacted and may continue to impact their ability to fulfill their obligations to us in the event of a resurgence of COVID-19 or the rise of a variant of the virus. Although most tenant businesses have returned to operating at pre-pandemic levels, for certain categories of our tenants, such as dry cleaners and fitness tenants, the negative impact of COVID-19 was more severe and the recovery is still in progress. Cash flow generated by the businesses of certain tenants may not be sufficient for such tenants to meet their obligations to us and in some cases we may need to secure replacement tenants. Our financial position could be weakened and our ability to fulfill our obligations under our indebtedness and make distributions to our shareholders could be limited if a number of our tenants were unable to meet their obligations to us or failed to renew or extend their relationships with us as their lease terms expire, or if we were unable to lease or re-lease our properties on economically favorable terms.

 Inflation may adversely affect our financial condition and results of operations.

 Inflation has become a growing concern. Inflationary price increases could have an adverse effect on consumer spending, which could impact our tenants' sales and, in turn, our tenants' business operations. This could affect the amount of rent these tenants pay, including if their leases provide for percentage rent or percentage of sales rent, and their ability to pay rent. Also, inflation could cause increases in operating expenses, which could increase occupancy costs for tenants and, to the extent that we are unable to recover operating expenses from tenants, could increase operating expenses for us. In addition, if the rate of inflation exceeds the scheduled rent increases included in our leases, then our net operating income and our profitability would decrease. Continued inflation could also result in further increases in market interest rates, which could not only negatively impact consumer spending and tenant investment decisions but would also increase the borrowing costs associated with our existing or any future variable rate debt, to the extent such rates are not effectively hedged or fixed, or any future debt that we incur.

 Disruption in capital markets could adversely impact acquisition activities and pricing of real estate assets.

 Volatility or other disruption in capital markets could adversely affect our access to or the cost of debt and equity capital, which could adversely affect our acquisition and other investment activities. Disruptions could include price volatility or decreased demand in equity markets, further increasing interest rates, tightening of underwriting standards by lenders and credit rating agencies and the significant inventory of unsold collateralized mortgage backed securities in the market. As a result, we may not be able to obtain favorable equity and debt financing in the future or at all. This may impair our ability to acquire properties at favorable returns or adversely affect our returns on investments in development and re-development projects, which may adversely affect our results of operations and distributions to shareholders. Turmoil in the capital markets could adversely impact the overall amount of capital available to invest in real estate, which may result in price or value decreases of real estate assets.

 All of our properties are subject to property taxes that may increase in the future, which could adversely affect our cash flow.

 Our properties are subject to property taxes that may increase as property tax rates change and as the properties are assessed or reassessed by taxing authorities. While we require our tenants to pay taxes, as the owner of the properties, we are ultimately responsible for payment of the taxes to the government. If property taxes increase, our tenants may be unable to make the required tax payments, ultimately requiring us to pay the taxes. In addition, we will generally be responsible for property taxes related to any vacant space.

 Our assets may be subject to impairment charges.

 We periodically evaluate our real estate investments and other assets for impairment indicators. The judgment regarding the existence of impairment indicators is based on factors such as market conditions, tenant performance and legal structure. If we determine that a significant impairment has occurred, we would be required to make an adjustment to the net carrying value of the asset, which could have a material adverse effect on our results of operations and funds from operations in the period in which the write-off occurs.

 Compliance or failure to comply with laws requiring access to our properties by disabled persons could result in substantial cost.

 The ADA and other federal, state and local laws generally require public accommodations be made accessible to disabled persons. Noncompliance with these laws could result in the imposition of fines by the government or the award of damages to private litigants. These laws may require us to modify our existing properties, which could require a significant investment of our cash resources that could otherwise be invested in more productive assets. These laws may also restrict renovations by requiring improved access to such buildings by disabled persons or may require us to add other structural features which increase our construction costs. Legislation or regulations adopted in the future may impose further obligations, restrictions or increased compliance costs on us with respect to improved access by disabled persons. We may incur unanticipated expenses that may be material to our financial condition or results of operations to comply with ADA and other federal, state and local laws, or in connection with lawsuits brought by private litigants.

 We face intense competition, which may decrease, or prevent increases of, the occupancy and rental rates of our properties.

 We compete with a number of developers, owners and operators of commercial real estate, many of whom own properties similar to ours in the same markets in which our properties are located. If our competitors offer space at rental rates below current market rates, or below the rental rates we currently charge our tenants, we may lose existing or potential tenants and may be pressured to reduce our rental rates below those we currently charge or to offer more substantial rent abatements, tenant improvements, early termination rights or below-market renewal options in order to retain tenants when their leases expire. This competitive environment could have a material adverse effect on our ability to lease our properties or any newly developed or acquired property, as well as on the rents charged.

 Our acquisition strategy includes acquiring distressed commercial real estate, and we could face significant competition from other investors, REITs, hedge funds, private equity funds and other private real estate investors with greater financial resources and access to capital. Therefore, we may not be able to compete successfully for investments. In addition, the number of entities and the amount of purchasers competing for suitable investments may increase, all of which could result in competition for accretive acquisition opportunities and adversely affect our business plan and our ability to maintain our current dividend rate.

 Risks Associated with Our Operations

 Because a majority of our GLA is in the Houston and Phoenix metropolitan areas, an economic downturn in either area could adversely impact our operations and ability to make distributions to our shareholders.

 The majority of our assets and revenues are currently derived from properties located in the Houston and Phoenix metropolitan areas. As of December 31, 2023, 22% and 47% of our GLA was located in Houston and Phoenix, respectively. Our results of operations are directly affected by our ability to attract financially sound commercial tenants. A significant economic downturn in the Houston or Phoenix metropolitan area may adversely impact our ability to locate and retain financially sound tenants, could have an adverse impact on our existing tenants' revenues, costs and results of operations and may adversely affect their ability to meet their obligations to us. Likewise, we may be required to lower our rental rates to attract desirable tenants in such an environment. Consequently, because of the geographic concentration among our current assets, if either the Houston or Phoenix metropolitan area were to experience an economic downturn, our operations and ability to make distributions to our shareholders could be adversely impacted.

 Pandemics, epidemics, or other health crises could materially and adversely impact and disrupt our business, financial condition, results of operations and cash flows.

 The potential resurgence of COVID-19, emergence of new variants, or future pandemics or health crises may intensify other risks outlined herein, potentially leading to adverse effects on our business, financial position, operational results, cash flows, and market value. These events may affect our business in the following manners:

 •

 closures of, or other operational issues at, our properties resulting from government or tenant action;

 •

 changes in consumer behavior in favor of e-commerce, which could result in reduced economic brick-and-mortar retail activity impacting our tenants' ability to meet their rental and other obligations to us in full or at all;

 •

 the ability of our tenants who have been granted rent deferrals to timely pay deferred rent;

 •

 any inability to renew leases or lease vacant space on favorable terms, or at all;

 •

 tenant bankruptcies;

 •

 liquidity issues resulting from reduced cash flows from operations;

 •

 negative impacts to the credit and/or capital markets making it difficult to access capital on favorable terms or at all;

 •

 impairment in value of our tangible or intangible assets;

 •

 a general decline in business activity and demand for real estate transactions adversely affecting our ability to grow our portfolio of properties, dispose of non-core properties and service our indebtedness;

 •

 supply chain disruptions adversely affecting our tenants' operations, as well as general labor shortages; and

 •

 impacts on the health of our personnel and a disruption in the continuity of our business.

 Because substantially all of our income is derived from rentals of commercial real property, our business, income, cash flow, results of operations, financial condition, liquidity, prospects and ability to service our debt obligations and our ability to pay dividends and other distributions to our shareholders would be adversely affected if a significant number of tenants are unable to meet their obligations or their revenues decline. The extent to which a resurgence of COVID-19 pandemic, or a future pandemic, impacts our operations and those of our tenants will depend on future developments, which are highly uncertain and cannot be predicted with confidence.

 We lease our properties to approximately 1,500 tenants and leases for approximately 10% to 20% of our GLA expire annually. Each year we face the risk of non-renewal of a significant percentage of our leases and the cost of re-leasing a significant amount of our available space, and our failure to meet leasing targets and control the cost of re-leasing our properties could adversely affect our rental revenue, operating expenses and results of operations.

 Our Community Centered Property business model produces shorter term leases to smaller, non-national tenants, and substantially all of our revenues consist of base rents received under these leases. As of December 31, 2023, approximately 33% of the aggregate GLA of our properties is subject to leases that expire prior to December 31, 2025. We are subject to the risk that:

 •

 tenants may choose not to, or may not have the financial resources to, renew these leases;

 •

 we may experience significant costs associated with re-leasing a significant amount of our available space;

 •

 we may experience difficulties and significant time lags re-leasing vacated space, which may cause us to fail to meet our occupancy and average base rent targets and experience increased costs of re-leasing; and

 •

 the terms of any renewal or re-lease may be less favorable than the terms of the current leases.

 We routinely seek to renew leases with our existing tenants prior to their expiration and typically begin discussions with tenants as early as 18 months prior to the expiration date of the existing lease. While our early renewal program and other leasing and marketing efforts provide early focus on expiring leases, and have generally been effective in producing lease renewals prior to expiration of the leases at rates comparable to or slightly in excess of the current rates, market conditions, including new supply of properties, and macroeconomic conditions in our markets and nationally, including rising interest rates, could adversely impact our renewal rate and/or the rental rates we are able to negotiate. If any of these risks materialize, our rental revenue, operating expenses and results of operations could be adversely affected.

 Many of our tenants are small businesses, which may have a higher risk of bankruptcy or insolvency.

 Many of our tenants are small businesses that depend primarily on cash flows from their operations to pay their rent and without other resources could be at a higher risk of bankruptcy or insolvency than larger, national tenants. If tenants are unable to comply with the terms of our leases, we may be forced to modify the leases in ways that are unfavorable to us. Alternatively, the failure of a tenant to perform under a lease could require us to declare a default, repossess the space and find a suitable replacement tenant. There is no assurance that we would be able to lease the space on substantially equivalent or better terms than the prior lease, or at all, or successfully reposition the space for other uses. If one or more of our tenants files for bankruptcy relief, the Bankruptcy Code provides that a debtor has the option to assume or reject the unexpired lease within a certain period of time.

 Any bankruptcy filing by or relating to one or more of our tenants could bar all efforts by us to collect pre-bankruptcy debts from that tenant or seize its property. A tenant bankruptcy could also delay our efforts to collect past due balances under the lease and could ultimately preclude collection of all or a portion of these sums. It is possible that we may recover substantially less than the full value of any unsecured claims we hold, if any. Furthermore, dealing with a tenant's bankruptcy or other default may divert management's attention and cause us to incur substantial legal and other costs. The bankruptcy or insolvency of a number of smaller tenants may have an adverse impact on our business, financial condition and results of operations, our ability to make distributions to our shareholders and the trading price of our common shares.

 Uninsured losses relating to real property or excessively expensive premiums for insurance coverage may adversely affect our returns.

 We attempt to adequately insure all of our properties to cover casualty losses. However, there are types of losses, generally catastrophic in nature, such as losses due to wars, acts of terrorism, earthquakes, floods, hurricanes, pollution or environmental matters, including as a result of climate change, which are uninsurable or not economically insurable, or may be insured subject to limitations, such as large deductibles or co-payments. Our current geographic concentration in the Houston metropolitan area exposes us to physical risks from climate change and potentially increases the risk of damage to our portfolio due to hurricanes. Insurance risks associated with potential terrorism acts could sharply increase the premiums we pay for coverage against property and casualty claims. In some instances, we may be required to provide other financial support, either through financial assurances or self-insurance, to cover potential losses. We cannot assure you that we will have adequate coverage for these losses. Also, to the extent we must pay unexpectedly large insurance premiums, we could suffer reduced earnings that would result in less cash to be distributed to shareholders.

 Discovery of previously undetected environmentally hazardous conditions may adversely affect our operating results.

 Under various federal, state and local environmental laws, ordinances and regulations, a current or previous owner or operator of real property may be liable for the cost of removal or remediation of hazardous or toxic substances on, under or in its property. The costs of removal or remediation could be substantial. These laws often impose liability whether or not the owner or operator knew of, or was responsible for, the presence of any hazardous or toxic substances. Environmental laws also may impose restrictions on the manner in which a property may be used or businesses may be operated, and these restrictions may require substantial expenditures. Environmental laws provide for sanctions in the event of noncompliance and may be enforced by governmental agencies or, in certain circumstances, by private parties. Certain environmental laws and common law principles could be used to impose liability for release of and exposure to hazardous substances, including asbestos containing materials into the air. In addition, third parties may seek recovery from owners or operators of real properties for personal injury or property damage associated with exposure to released hazardous substances. The cost of defending against claims of liability, of compliance with environmental regulatory requirements, of remediating any contaminated property, or of paying personal injury claims could materially adversely affect our business, assets or results of operations and, consequently, amounts available for distributions to our shareholders.

 Certain of our properties currently include or have in the past included a dry cleaning facility as a tenant. See "Business - Compliance with Governmental Regulations."

 Our success depends in part on our ability to execute our Community Centered Property strategy.

 Our Community Centered Property strategy requires intensive management of a large number of small spaces and small tenant relationships. Our success depends in part upon our management's ability to identify potential Community Centered Properties and find and maintain the appropriate tenants to create such a property. Lack of market acceptance of our Community Centered Property strategy or our inability to successfully attract and manage a large number of tenant relationships could adversely affect our occupancy rates, operating results and dividend rate.

 Our business is significantly influenced by demand for retail space generally, and a decrease in such demand may have a greater adverse effect on our business than if we owned a more diversified real estate portfolio.

 Because our portfolio of properties consists primarily of community and neighborhood shopping centers, a decrease in the demand for retail space, due to the economic factors discussed above or otherwise, may have a greater adverse effect on our business and financial condition than if we owned a more diversified real estate portfolio. The market for retail space has been, and could continue to be, adversely affected by weakness in the national, regional and local economies, the adverse financial conditions of some retailing companies, the ongoing consolidation in the retail sector, the excess amount of retail space in a number of markets, health and safety concerns and increasing online consumer purchases.

 We face risks relating to cybersecurity attacks, loss of confidential information and other business disruptions.

 Our business is at risk from and may be impacted by cybersecurity attacks, including attempts to gain unauthorized access to our confidential data and other electronic security breaches. Such cyber-attacks can range from individual attempts to gain unauthorized access to our information technology systems to more sophisticated security threats including advance hacking tools and techniques such as artificial intelligence. We have experienced cyber-attacks, and while to date none of these incidents have been material to our operations, we expect to continue to face such threats in the future. We employ a number of measures to prevent, detect and mitigate these threats, but especially in light of increasingly sophisticated techniques used in cybersecurity attacks, there is no guarantee such efforts will be successful in preventing future cyber-attacks where we cannot fully anticipate, detect, repel, or implement fully effective preventative measures. In addition, cybersecurity incidents could compromise the confidential information of our tenants, employees and third party vendors that we collect in the ordinary course of our business. Laws and expectations relating to data protection and privacy vary by jurisdiction and continue to evolve, and we believe increased regulation in additional jurisdictions is likely to develop in the future. For example, the California Consumer Privacy Act (CCPA) that went into effect on January 1, 2020, as amended to include additional privacy protection for consumers by the California Privacy Rights Act (CPRA) that went into effect on January 1, 2023, requires covered companies to, among other things, provide new disclosures to California consumers, and afford such consumers new abilities to opt-out of certain sales of personal information. A cyber-attack or our ability or perceived inability to comply with regulations related to cybersecurity and/or data protection and privacy could materially and adversely affect the efficiency of our business operations, which in turn could have a material adverse effect on our reputation, competitiveness and results of operations. Please refer to Item 1C of this 10-K for additional information.

 We are subject to risks related to corporate social and environmental responsibility and reputation.

 A number of factors influence our reputation and brand value, including how we are perceived by our tenants, business partners, investors, associates, other stakeholders and the communities in which we do business. We face increasing scrutiny related to environmental, social and governance ("ESG") activities and disclosures and risk damage to our reputation if we fail to act appropriately and responsibly in ESG matters, including, among others, environmental stewardship, supply chain management, climate change, human rights, diversity and inclusion, workplace ethics and conduct, philanthropic activity and support for the communities we serve and in which we operate. Any damage to our reputation could impact the willingness of our business partners and customers to do business with us, or could negatively impact our associate hiring, engagement and retention, all of which could have a material adverse effect on our business, results of operations and cash flows.

 Loss of our key management could adversely affect performance and the value of our common shares.

 We are dependent on the efforts of our key management. Although we believe qualified replacement could be found for any departures of key executives, the loss of their services could adversely affect our performance and the value of our common shares.

 Risk related to the redemption of our partnership units in Pillarstone Capital REIT Operating Partnership.

 As set forth in the Amended and Restated Limited Partnership Agreement of Pillarstone OP, dated as of December 8, 2016 (the "Pillarstone Partnership Agreement"), we have the contractual right to have our limited partnership interests in Pillarstone redeemed at our discretion. However, upon receipt of a redemption notice, Pillarstone OP has the option to pay the applicable redemption price in cash, based on the market value of Pillarstone REIT common shares, or in Pillarstone REIT common shares.

 On December 26, 2021, the Board of Trustees of Pillarstone REIT adopted a new shareholder rights agreement (the "Pillarstone Rights Agreement"). Because Pillarstone REIT sought to use the Pillarstone Rights Agreement to prevent Whitestone OP from exercising its contractual Redemption Right, on July 12, 2022, Whitestone OP filed suit against Pillarstone REIT in the Court of Chancery of the State of Delaware challenging the Pillarstone Rights Agreement.

 On January 25, 2024, the Delaware Court of Chancery: held that Pillarstone breached the implied covenant of good faith and fair dealing when it adopted the Pillarstone Rights Agreement that thwarted Whitestone OP from exercising the unfettered contractual redemption right it obtained in connection with its investment in the partnership; and the Court held that the Rights Plan was unenforceable as to the limited partner and allowed Whitestone OP to exercise its redemption right; allowed Pillarstone to determine the current value of the Partnership's assets; and, as necessary, later enter a monetary judgment against Pillarstone for the difference between the amount Whitestone would have received in or around December 2021 and the current value.

 On January 25, 2024, the Company exercised its notice of redemption for substantially all of its investment in Pillarstone OP.

 On March 4, 2024, Pillarstone REIT authorized and filed the Chapter 11 bankruptcy of itself, Pillarstone OP, and the remainder of its special purpose entities in the United States Bankruptcy Court for the Northern District of Texas.

 As of the date of this filing, Whitestone has not received consideration for its redemption of its equity investment in Pillarstone OP as required by the partnership agreement. We intend to pursue collection of amounts due from Pillarstone OP through all means, including further litigation if necessary and while we do not know the ultimate amount to be collected, we believe the amount will be in excess of the current carrying value of our equity investment in Pillarstone OP.

 Risk of Litigation

 We assess the likelihood of any adverse judgments or outcomes to our cases, as well as potential ranges of probable losses, in a manner consistent with FASB ASC 450, Contingencies. However, it is possible that our financial position, cash flow, or results of operations could be negatively affected in any particular period by the resolution of one or more proceedings.

 We establish reserves for specific legal matters when we determine that the likelihood of loss is probable and the amount of loss can be reasonably estimated. These reserves are reevaluated periodically and adjusted as necessary to reflect changes in circumstances. Due to the uncertainty surrounding litigation, actual losses may differ from these estimates.

 Litigation is subject to inherent uncertainties, and there can be no assurance that the resolution of any particular legal proceeding will not have a material adverse impact on our business, financial condition, or results of operations. Depending on the nature and timing of any such disputes and their resolutions, litigation could lead to charges that may be material to our financial statements in any given reporting period.

 Shareholders and potential investors are cautioned to consider the risks and uncertainties associated with legal proceedings, as detailed herein, when making investment decisions regarding the Company's securities.

 Risk associated with the Kroger acquisition of Albertsons.

 On October 14, 2022, Kroger Co. ("Kroger") announced its intention to acquire Albertsons Companies, Inc. ("Albertsons"). In connection with obtaining the regulatory clearance necessary to close the transaction, C&S Wholesale Grocers has entered into a definitive agreement to purchase Albertsons' 413 stores. As of December 31, 2023, Whitestone REIT had 5 grocers owned by Albertsons. It does not appear that any of the Albertsons' stores currently leasing from Whitestone REIT are likely to be purchased by C&S Wholesale Grocers. Kroger has stated that they anticipate the closing will occur by August of 2024 and that they are in active and ongoing dialogue with the Federal Trade Commission and individual state Attorneys General regarding the proposed merger and divestiture plan.

 Risks Associated with Our Indebtedness and Financing

 Current market conditions could adversely affect our ability to refinance existing indebtedness or obtain additional financing for growth on acceptable terms or at all, which could adversely affect our ability to grow, our interest cost and our results of operations.

 Turbulence in the United States credit markets have in the past, and may in the future impact liquidity in the debt markets, making financing terms for borrowers less attractive, and may result in the unavailability of various types of debt financing. Reductions in our available borrowing capacity, or inability to refinance our revolving credit facility when required or when business conditions warrant, could have a material adverse effect on our business, financial condition and results of operations. In addition, we mortgage many of our properties to secure payment of indebtedness. If we are not successful in refinancing our mortgage debt upon maturity, then the property could be foreclosed upon or transferred to the mortgagee, or we might be forced to dispose of some of our properties upon disadvantageous terms, with a consequent loss of income and asset value. A foreclosure or disadvantageous disposal on one or more of our properties could adversely affect our ability to grow, financial condition, interest cost, results of operations, cash flow and ability to make distributions to our shareholders.

 Furthermore, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to that refinanced indebtedness would increase. Higher interest rates on newly incurred debt may negatively impact us as well. If interest rates continue to increase, our interest costs and overall costs of capital will increase, which could adversely affect our transaction and development activity, financial condition, results of operation, cash flow, our ability to pay principal and interest on our debt and our ability to make distributions to our shareholders.

 Our failure to hedge effectively against interest rate changes may adversely affect results of operations.

 We currently have mortgages that bear interest at variable rates, and we may incur additional variable rate debt in the future. Accordingly, further increases in interest rates on variable rate debt will continue to increase our interest expense, which could reduce net earnings and cash available for payment of our debt obligations and distributions to our shareholders.

 We may seek to manage our exposure to interest rate volatility by using interest rate hedging arrangements, such as interest cap agreements and interest rate swap agreements. These agreements involve risks, such as the risk that counterparties may fail to honor their obligations under these arrangements, that these arrangements may not be effective in reducing our exposure to interest rate changes and that a court could rule that such an agreement is not legally enforceable. In the past, we have used derivative financial instruments to hedge interest rate risks related to our variable rate borrowings. We will not use derivatives for speculative or trading purposes and intend only to enter into contracts with major financial institutions based on their credit rating and other factors, but we may choose to change this practice in the future. As of December 31, 2023, we had fixed rate hedges on $315 million of our variable rate unsecured credit facility. We may enter into additional interest rate swap agreements for our variable rate debt not currently subject to hedges, which totaled $96 million as of December 31, 2023. Hedging may reduce the overall returns on our investments. Failure to hedge effectively against interest rate changes may materially and adversely affect our results of operations.

 We currently have and may incur additional mortgage indebtedness and other borrowings, which may increase our business risks and may adversely affect our ability to make distributions to our shareholders.

 If we determine it to be in our best interests, we may, in some instances, acquire real properties by using either existing financing or borrowing new funds. In addition, we may incur or increase our current mortgage debt to obtain funds to acquire additional properties. We may also borrow funds if necessary to satisfy the REIT distribution requirement described above, or otherwise as may be necessary or advisable to ensure that we maintain our qualification as a REIT for federal income tax purposes.

 As of December 31, 2023, we had outstanding indebtedness, net of cash, of $636.0 million, including, through our Operating Partnership, $92.9 million aggregate principal amount of the Notes (as defined below) and $411.0 million drawn on the 2022 Facility (as defined below). As of December 31, 2023, our unused borrowing capacity under our 2022 Facility was $104.0 million. Obligations under the Notes and the 2022 Facility are guaranteed by the Company and certain subsidiary guarantors. Our current debt agreements, including the agreements governing the Notes and the 2022 Facility, contain, and any future debt agreements may contain, a number of restrictive and financial covenants that impose significant operating and financial constraints on us. Such restrictive covenants may significantly limit our ability to:

 •

 incur additional debt, including issuing guarantees;

 •

 incur liens;

 •

 make certain investments;

 •

 sell or otherwise dispose of assets;

 •

 make acquisitions;

 •

 engage in mergers or consolidations or certain other "change of control" transactions;

 •

 make distributions to our shareholders;

 •

 engage in restructuring activities;

 •

 engage in certain sale and leaseback transactions; and

 •

 issue or repurchase common shares or other securities.

 Such agreements may also require us to satisfy other requirements, including maintaining certain financial ratios and condition tests. Our ability to meet these requirements can be affected by events beyond our control, and we may be unable to meet them. To the extent we fail to meet any such requirements and are in default under our debt obligations, our financial condition may be materially adversely affected. Further, these restrictions may limit our ability to engage in activities that could otherwise benefit us. To the extent that we are unable to engage in activities that support the growth, profitability and competitiveness of our business, our results of operations may be materially adversely affected.

 We may also incur mortgage debt on a particular property if we believe the property's projected cash flow is sufficient to service the mortgage debt. As of December 31, 2023, we had approximately $136.7 million of mortgage debt secured by five of our properties. If there is a shortfall in cash flow, however, the amount available for distributions to shareholders may be affected. In addition, incurring mortgage debt increases the risk of loss because defaults on such indebtedness may result in loss of property in foreclosure actions initiated by lenders. For tax purposes, a foreclosure of any of our properties would be treated as a sale of the property for a purchase price equal to the outstanding balance of the debt secured by the mortgage. If the outstanding balance of the debt secured by the mortgage exceeds our tax basis in the property, we would recognize taxable income on foreclosure, but would not receive any cash proceeds. We may give lenders full or partial guarantees for mortgage debt incurred by the entities that own our properties. When we give a guaranty on behalf of an entity that owns one of our properties, we will be responsible to the lender for satisfaction of the debt if it is not paid by that entity. If any mortgages contain cross-collateralization or cross-default provisions, there is a risk that more than one property may be affected by a default. If any of our properties are foreclosed upon due to a default, our ability to pay cash distributions to our shareholders may be adversely affected. For more discussion, see "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources."

 If we set aside insufficient working capital or are unable to secure funds for future tenant improvements, we may be required to defer necessary property improvements, which could adversely impact the quality of our properties and our results of operations.

 When tenants do not renew their leases or otherwise vacate their space, it is possible that, in order to attract replacement tenants, we may be required to expend substantial funds for tenant improvements and refurbishments to the vacated space. If we have insufficient working capital reserves, we will have to obtain financing from other sources. Because most of our leases provide for tenant reimbursement of operating expenses, we have not established a permanent reserve for maintenance and repairs for our properties. However, to the extent that we have insufficient funds for such purposes, we may establish reserves for maintenance and repairs of our properties out of cash flow generated by operating properties or out of non-liquidating net sale proceeds. If these reserves or any reserves otherwise established are insufficient to meet our cash needs, we may have to obtain financing from either affiliated or unaffiliated sources to fund our cash requirements. We cannot assure you that sufficient financing will be available or, if available, will be available on economically feasible terms or on terms acceptable to us. Additional borrowing for working capital purposes will increase our interest expense, and therefore our financial condition and our ability to pay cash distributions to our shareholders may be adversely affected. In addition, we may be required to defer necessary improvements to our properties that may cause our properties to suffer from a greater risk of obsolescence or a decline in value, or a greater risk of decreased cash flow as a result of fewer potential tenants being attracted to our properties. If this happens, we may not be able to maintain projected rental rates for affected properties, and our results of operations may be negatively impacted.

 We have in the past and may continue to structure acquisitions of property in exchange for limited partnership units in our Operating Partnership on terms that could limit our liquidity or our flexibility.

 We have in the past and may continue to acquire properties by issuing limited partnership units in our Operating Partnership ("OP units") in exchange for a property owner contributing property to the Operating Partnership. If we enter into such transactions, in order to induce the contributors of such properties to accept OP units, rather than cash, in exchange for their properties, it may be necessary for us to provide them with additional incentives. For instance, our Operating Partnership's limited partnership agreement provides that any holder of OP units may redeem such units for cash, or, at our option, common shares on a one-for-one basis. We may, however, enter into additional contractual arrangements with contributors of property under which we would agree to redeem a contributor's OP units for our common shares or cash, at the option of the contributor, at set times. If the contributor required us to redeem OP units for cash pursuant to such a provision, it would limit our liquidity and thus our ability to use cash to make other investments, satisfy other obligations or pay distributions. Moreover, if we were required to redeem OP units for cash at a time when we did not have sufficient cash to fund the redemption, we might be required to sell one or more properties to raise funds to satisfy this obligation. Furthermore, we might agree that if distributions the contributor received as a limited partner in our Operating Partnership did not provide the contributor with a defined return, then upon redemption of the contributor's OP units, we would pay the contributor an additional amount necessary to achieve that return. Such a provision could further negatively impact our liquidity and flexibility. Finally, in order to allow a contributor of a property to defer taxable gain on the contribution of property to our Operating Partnership, we might agree not to sell a contributed property for a defined period of time or until the contributor redeemed the contributor's OP units for cash or our common shares. Such an agreement would prevent us from selling those properties, even if market conditions made such a sale favorable to us.

 Risks Associated with Income Tax Laws

 If we fail to qualify as a REIT, our operations and distributions to shareholders would be adversely impacted.

 We intend to continue to be organized and to operate so as to qualify as a REIT under the Code. A REIT generally is not taxed at the corporate level on income it currently distributes to its shareholders. Qualification as a REIT involves the application of highly technical and complex rules for which there are only limited judicial or administrative interpretations. The determination of various factual matters and circumstances not entirely within our control may affect our ability to continue to qualify as a REIT. In addition, new legislation, new regulations, administrative interpretations or court decisions could significantly change the tax laws, possibly with retroactive effect, with respect to qualification as a REIT or the federal income tax consequences of such qualification.

 If we were to fail to qualify as a REIT in any taxable year:

 •

 we would not be allowed to deduct our distributions to shareholders when computing our taxable income;

 •

 we would be subject to federal income tax on our taxable income at regular corporate rates;

 •

 we would be disqualified from being taxed as a REIT for the four taxable years following the year during which qualification was lost, unless entitled to relief under certain statutory provisions;

 •

 our cash available for distributions to shareholders would be reduced; and

 •

 we may be required to borrow additional funds or sell some of our assets in order to pay corporate tax obligations that we may incur as a result of our disqualification.

 We may need to incur additional borrowings to meet the REIT minimum distribution requirement and to avoid excise tax.

 In order to maintain our qualification as a REIT, we are required to distribute to our shareholders at least 90% of our annual real estate investment trust taxable income (excluding any net capital gain and before application of the dividends paid deduction). In addition, we are subject to a 4% nondeductible excise tax on the amount, if any, by which certain distributions paid by us with respect to any calendar year are less than the sum of (i) 85% of our ordinary income for that year, (ii) 95% of our net capital gain for that year and (iii) 100% of our undistributed taxable income from prior years. Although we intend to pay distributions to our shareholders in a manner that allows us to meet the 90% distribution requirement and avoid this 4% excise tax, we cannot assure you that we will always be able to do so.

 Our income consists almost solely of our share of our Operating Partnership's income, and the cash available for distribution by us to our shareholders consists of our share of cash distributions made by our Operating Partnership. Because we are the sole general partner of our Operating Partnership, our board of trustees determines the amount of any distributions made by our Operating Partnership. Our board of trustees may consider a number of factors in authorizing distributions, including:

 •

 the amount of cash available for distribution;

 •

 our Operating Partnership's financial condition;

 •

 our Operating Partnership's capital expenditure requirements; and

 •

 our annual distribution requirements necessary to maintain our qualification as a REIT.

 Differences in timing between the actual receipt of income and actual payment of deductible expenses and the inclusion of income and deduction of expenses when determining our taxable income, as well as the effect of nondeductible capital expenditures and the creation of reserves or required debt amortization payments could require us to borrow funds on a short-term or long-term basis or make taxable distributions to our shareholders of our shares or debt securities to meet the REIT distribution requirement and to avoid the 4% excise tax described above. In these circumstances, we may need to borrow funds to avoid adverse tax consequences even if our management believes that the then prevailing market conditions generally are not favorable for borrowings or that borrowings would not be advisable in the absence of the tax consideration.

 If our Operating Partnership were classified as a " publicly traded partnership " taxable as a corporation for federal income tax purposes under the Code, we would cease to qualify as a REIT and would suffer other adverse tax consequences.

 We structured our Operating Partnership so that it would be classified as a partnership for federal income tax purposes. In this regard, the Code generally classifies "publicly traded partnerships" (as defined in Section 7704 of the Code) as associations taxable as corporations (rather than as partnerships), unless substantially all of their taxable income consists of specified types of passive income. In order to minimize the risk that the Code would classify our Operating Partnership as a "publicly traded partnership" for tax purposes, we placed certain restrictions on the transfer and/or redemption of our OP units. If the Internal Revenue Service were to assert successfully that our Operating Partnership is a "publicly traded partnership," and substantially all of its gross income did not consist of the specified types of passive income, the Code would treat our Operating Partnership as an association taxable as a corporation.

 In such event, the character of our assets and items of gross income would change and would prevent us from continuing to qualify as a REIT. In addition, the imposition of a corporate tax on our Operating Partnership would reduce our amount of cash available for payment of distributions by us to our shareholders.

 Complying with REIT requirements may cause us to forego otherwise attractive opportunities or liquidate otherwise attractive investments.

 To qualify as a REIT for federal income tax purposes, we must continually satisfy tests concerning, among other things, the sources of our income, the nature and diversification of our assets, the amounts we distribute to our shareholders and the ownership of our shares. In order to meet these tests, we may be required to forego investments we might otherwise make. Thus, compliance with the REIT requirements may hinder our performance.

 In particular, we must ensure that at the end of each calendar quarter, at least 75% of the value of our assets consists of cash, cash items, government securities and qualified real estate assets. The remainder of our investment in securities (other than government securities and qualified real estate assets) generally cannot include more than 10% of the outstanding voting securities of any one issuer or more than 10% of the total value of the outstanding securities of any one issuer. In addition, in general, no more than 5% of the value of our assets (other than government securities and qualified real estate assets) can consist of the securities of any one issuer, and no more than 20% of the value of our total assets can be represented by the securities of one or more taxable REIT subsidiaries. If we fail to comply with these requirements at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain statutory relief provisions to avoid losing our REIT qualification and suffering adverse tax consequences. As a result, we may be required to liquidate otherwise attractive investments. These actions could have the effect of reducing our income and amounts available for distribution to our shareholders.

 Dividends payable by REITs do not qualify for the reduced tax rates available for some dividends.

 For non-corporate taxpayers the maximum tax rate applicable to "qualified dividend income" paid by regular "C" corporations to U.S. shareholders generally is 20%. Dividends payable by REITs, however, generally are not eligible for the reduced rates on qualified dividend income. Instead, our ordinary dividends generally are taxed at the higher tax rates applicable to ordinary income, the current maximum rate of which is 37%. However, for taxable years prior to 2026, individual stockholders are generally allowed to deduct 20% of the aggregate amount of ordinary dividends distributed by us, subject to certain limitations, which would reduce the maximum marginal effective tax rate for individuals on the receipt of such ordinary dividends to 29.6%.

 Complying with REIT requirements may limit our ability to hedge effectively and may cause us to incur tax liabilities.

 The REIT provisions of the Code substantially limit our ability to hedge our liabilities. Any income from a hedging transaction that we enter into to manage risk of interest rate changes, price changes or currency fluctuations with respect to borrowings made or to be made to acquire or carry real estate assets does not constitute "gross income" for purposes of the 75% or 95% gross income tests. To the extent that we enter into other types of hedging transactions, the income from those transactions is likely to be treated as non-qualifying income for purposes of both of the gross income tests. As a result of these rules, we may need to limit our use of advantageous hedging techniques or implement those hedges through taxable REIT subsidiaries. This could increase the cost of our hedging activities because any taxable REIT subsidiary that we may form would be subject to tax on gains or expose us to greater risks associated with changes in interest rates than we would otherwise want to bear. In addition, losses in taxable REIT subsidiaries will generally not provide any tax benefit, except for being carried forward against future taxable income in the taxable REIT subsidiaries.

 Changes to the U.S. federal income tax laws, including the enactment of certain tax reform measures, could have an adverse impact on our business and financial results.

 We cannot predict whether, when, or to what extent any new U.S. federal tax laws, regulations, interpretations, or rulings will impact the real estate investment industry or REITs. Prospective investors are urged to consult their tax advisors regarding the effect of potential future changes to the federal tax laws on an investment in our shares.

 Risks Related to Ownership of our Common Shares

 Increases in market interest rates may result in a decrease in the value of our common shares.

 One of the factors that may influence the price of our common shares will be the dividend distribution rate on the common shares (as a percentage of the price of our common shares) relative to market interest rates. If market interest rates continue to rise, prospective purchasers of shares of our common shares may expect a higher distribution rate. Higher interest rates would not, however, result in more funds being available for distribution and, in fact, would likely increase our borrowing costs and might decrease our funds available for distribution. We therefore may not be able, or we may not choose, to provide a higher distribution rate. As a result, prospective purchasers may decide to purchase other securities rather than our common shares, which would reduce the demand for, and result in a decline in the market price of, our common shares.

 Maryland takeover statutes may deter others from seeking to acquire us and prevent shareholders from making a profit in such transactions.

 The Maryland General Corporation Law ("MGCL") contains many provisions, such as the business combination statute and the control share acquisition statute, that are designed to prevent, or have the effect of preventing, someone from acquiring control of us. The business combination statute, subject to limitations, prohibits certain business combinations between us and an "interested shareholder" (defined generally as any person who beneficially owns 10% or more of the voting power of our outstanding voting shares or an affiliate or associate of our Company who, at any time within the two-year period prior to the date in question, was the beneficial owner of 10% or more of the voting power of our then outstanding shares) or an affiliate of an interested shareholder for five years after the most recent date on which the person becomes an interested shareholder and thereafter imposes super-majority voting requirements on these combinations. The control share acquisition statute provides that "control shares" of our Company (defined as shares which, when aggregated with other shares controlled by the shareholder (except solely by virtue of a revocable proxy), entitle the shareholder to exercise one of three increasing ranges of voting power in electing trustees) acquired in a "control share acquisition" (defined as the direct or indirect acquisition of ownership or control of issued and outstanding control shares) have no voting rights except to the extent approved by our shareholders by the affirmative vote of at least two-thirds of all the votes entitled to be cast on the matter, excluding all interested shares.

 We are currently subject to the control share acquisition statute, although our board of trustees may amend our Amended and Restated Bylaws, or our bylaws, without shareholder approval, to exempt any acquisition of our shares from the statute. Our board of trustees has adopted a resolution exempting any business combination with any person from the business combination statute. The business combination statute (if our board of trustees revokes the foregoing exemption) and the control share acquisition statute could delay or prevent offers to acquire us and increase the difficulty of consummating any such offers, even if such a transaction would be in our shareholders' best interest.

 The MGCL, the Maryland REIT Law and our organizational documents limit shareholders ' rights to bring claims against our officers and trustees.

 The MGCL and the Maryland REIT Law provide that a trustee will not have any liability as a trustee so long as he performs his duties in good faith, in a manner he reasonably believes to be in our best interests, and with the care that an ordinarily prudent person in a like position would use under similar circumstances. In addition, our declaration of trust provides that no trustee or officer will be liable to us or to any shareholder for money damages except to the extent that (a) the trustee or officer actually received an improper benefit or profit in money, property or services, for the amount of the benefit or profit in money, property, or services actually received; or (b) a judgment or the final adjudication adverse to the trustee or officer is entered in a proceeding based on a finding in the proceeding the trustee's or officer's action or failure to act was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding. Finally, our declaration of trust authorizes our Company to obligate itself, and our bylaws obligate us, to indemnify and advance expenses to our trustees and officers to the maximum extent permitted by Maryland law.

 The terms of our employment agreements with our executive officers and severance arrangements with other employees and the terms of certain equity awards granted to our employees may deter others from seeking to acquire us or reduce the price of any such acquisition.

 We have entered into employment agreements with our executive officers and severance arrangements with other of our employees, and have granted equity awards to a number of our employees. In certain cases, upon a change of control acquisition of us, such agreements and awards would entitle the officer or employee to severance payments and vesting of otherwise unvested awards. The cost of these payments and the impact of the vesting of such awards could deter a third party from seeking to acquire us or could cause the price payable to shareholders in connection with any such acquisition to be lower than it otherwise may have been. These effects could delay or prevent offers to acquire us and increase the difficulty in consummating any such offers, even if such a transaction would be in our shareholders' best interests.

 We may issue preferred shares with a preference in distributions over our common shares, and our ability to issue preferred shares and additional common shares may deter or prevent a sale of our common shares in which you could profit.

 Our declaration of trust authorizes our board of trustees to issue up to 400,000,000 common shares and 50,000,000 preferred shares. Our board of trustees may amend our declaration of trust from time to time to increase or decrease the aggregate number of shares or the number of any class or series that we have authority to issue. In addition, our board of trustees may classify or reclassify any unissued common shares or preferred shares and may set the preferences, rights and other terms of the classified or reclassified shares. The terms of preferred shares could include a preference in distributions senior to our common shares. If we authorize and issue preferred shares with a distribution preference senior to our common shares, payment of any distribution preferences of outstanding preferred shares would reduce the amount of funds available for the payment of distributions on our common shares. Further, holders of preferred shares are normally entitled to receive a preference payment in the event we liquidate, dissolve or wind up before any payment is made to our common shareholders, likely reducing the amount our common shareholders would otherwise receive upon such an occurrence. In addition, under certain circumstances, the issuance of preferred shares or a separate class or series of common shares may render more difficult or tend to discourage:

 •

 a merger, tender offer or proxy contest;

 •

 assumption of control by a holder of a large block of our shares; or

 •

 removal of incumbent management.

 Future offerings of debt, which would be senior to our common shares upon liquidation, and/or preferred equity securities that may be senior to our common shares for purposes of distributions or upon liquidation, may adversely affect the market price of our common shares.

 In the future, we may attempt to increase our capital resources by making additional offerings of debt or preferred equity securities, including medium-term notes, trust preferred securities, senior or subordinated notes and preferred shares. Upon liquidation, holders of our debt securities and preferred shares and lenders with respect to other borrowings will receive distributions of our available assets prior to the holders of our common shares. Additional equity offerings may dilute the holdings of our existing shareholders or reduce the market price of our common shares, or both. Holders of our common shares are not entitled to preemptive rights or other protections against dilution. Our preferred shares, if issued, could have a preference on liquidating distributions or a preference on distribution payments that could limit our ability to pay distributions to the holders of our common shares. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, our common shareholders bear the risk of our future offerings reducing the market price of our common shares and diluting their share holdings in us.

 General Risk Factors

 Market disruptions may significantly and adversely affect our financial condition and results of operations.

 World financial markets have, from time to time, experienced significant disruption. Our results of operations may be sensitive to changes in overall economic conditions that impact tenants of our properties or tenant leasing practices. Adverse economic conditions affecting tenant income, such as employment levels, business conditions, interest rates, tax rates, fuel and energy costs and other matters, could reduce overall tenant leasing or cause tenants to shift their leasing practices. In addition, periods of economic slowdown or recession, further increasing interest rates or declining demand for real estate, or the public perception that any of these events may occur, could result in a general decline in rents or an increased incidence of defaults under existing leases. In addition, financial markets may again experience significant and prolonged disruption, including as a result of unanticipated events, or as a result of recent uncertainty regarding legislative and regulatory shifts relating to, among other things, taxation and trade, and which could adversely affect our tenants and our business in general. For example, a general reduction in consumer spending and the level of tenant leasing could adversely affect our ability to maintain our current tenants and gain new tenants, affecting our growth and profitability. Accordingly, if financial and macroeconomic conditions deteriorate, or if financial markets experience significant disruption, it could have a significant adverse effect on our cash flows, profitability, results of operations and the trading price of our common shares.

 The value of investments in our common shares will be directly affected by general economic and regulatory factors we cannot control or predict.

 Investments in real estate typically involve a high level of risk as the result of factors we cannot control or predict. One of the risks of investing in real estate is the possibility that our properties will not generate income sufficient to meet operating expenses or will generate income and capital appreciation, if any, at rates lower than those anticipated or available through investments in comparable real estate or other investments. The following factors may affect income from properties and yields from investments in properties and are generally outside of our control:

 •

 conditions in financial markets;

 •

 continuing deterioration of the brick-and-mortar retail industry;

 •

 over-building in our markets;

 •

 a reduction in rental income as the result of the inability to maintain occupancy levels;

 •

 adverse changes in applicable tax, real estate, environmental or zoning laws;

 •

 changes in general economic conditions or economic conditions in our markets;

 •

 a taking of any of our properties by eminent domain;

 •

 adverse local conditions (such as changes in real estate zoning laws that may reduce the desirability of real estate in the area);

 •

 acts of God, such as hurricanes, earthquakes or floods, health and safety epidemics, and other uninsured losses, some of which may increase due to climate change;

 •

 geopolitical instability, including the ongoing conflict between Russia and Ukraine, the conflict in the Gaza Strip and unrest in the Middle East;

 •

 changes in supply of or demand for similar or competing properties in an area;

 •

 changes in interest rates and availability of permanent debt capital, which may render the sale of a property difficult or unattractive; and

 •

 periods of high interest rates, inflation or tight money supply.

 Some or all of these factors may affect our properties, which could adversely affect our operations and ability to make distributions to shareholders.

 We may not be successful in consummating suitable acquisitions or investment opportunities, which may impede our growth and adversely affect the trading price of our common shares.

 Our ability to expand through acquisitions is integral to our business strategy and requires us to consummate suitable acquisition or investment opportunities that meet our criteria and are compatible with our growth strategy. We may not be successful in consummating acquisitions or investments in properties that meet our acquisition criteria on satisfactory terms or at all. Failure to consummate acquisitions or investment opportunities, the failure of an acquired property to perform as expected, or the failure to integrate successfully any acquired properties without substantial expense, delay or other operational or financial problems, would slow our growth, which could in turn adversely affect the trading price of our common shares.

 Our ability to acquire properties on favorable terms may be constrained by the following significant risks:

 •

 competition from other real estate investors with significant capital, including other REITs and institutional investment funds;

 •

 competition from other potential acquirers which may significantly increase the purchase price for a property we acquire, which could reduce our growth prospects;

 •

 unsatisfactory results of our due diligence investigations or failure to meet other customary closing conditions;

 •

 the failure of an acquired property to perform as expected; and

 •

 failure to finance an acquisition on favorable terms or at all.

 If any of these risks are realized, our business, financial condition and results of operations, our ability to make distributions to our shareholders and the trading price of our common shares may be materially and adversely affected.

 Our systems may not be adequate to support our growth, and our failure to successfully oversee our portfolio of properties could adversely affect our results of operations.

 We make no assurances that we will be able to adapt our portfolio management, administrative, accounting and operational systems, or hire and retain sufficient operational staff, to support our growth. Our failure to successfully oversee our current portfolio of properties or any future acquisitions or developments could have a material adverse effect on our results of operations and financial condition and our ability to make distributions.

 Shareholder activism efforts or unsolicited offers from a third-party could cause a material disruption to our business and financial results.

 We may be subject to various legal and business challenges due to actions instituted by shareholder activists or unsolicited third-party offers. Perceived uncertainties as to our future direction as a result of shareholder activism may lead to the perception of a change in the direction of the business or other instability and may affect our relationships with vendors, prospective and existing tenants, prospective and current employees and others. Proposed or future laws and regulations may increase the chance we become the target of shareholder activist campaigns, including ESG-related actions. If shareholder activist campaigns are initiated against us, our response to such actions could be costly and time-consuming, which could divert the attention and resources of the Board, Chief Executive Officer and senior management from the pursuit of our business strategies, which could harm our business, negatively impact our stock price, and have an adverse effect on our business and financial results.

 There can be no assurance that we will be able to pay or maintain cash distributions or that distributions will increase over time.

 There are many factors that can affect the availability and timing of cash distributions to shareholders. Distributions are based upon our funds from operations, financial condition, cash flows and liquidity, debt service requirements, capital expenditure requirements for our properties and other matters our board of trustees may deem relevant from time to time. If we do not have sufficient cash available for distributions, we may need to fund the shortage out of working capital or borrow to provide funds for such distributions, which would reduce the amount of capital available for real estate investments and increase our future interest costs.

 We can give no assurance that we will be able to continue to pay distributions or that distributions will increase over time. In addition, we can give no assurance that rents from our properties will increase, or that future acquisitions of real properties, mortgage loans or our investments in securities will increase our cash available for distributions to shareholders. Our actual results may differ significantly from the assumptions used by our board of trustees in establishing the distribution rate to shareholders. Our inability to make distributions, or to make distributions at expected levels, could result in a decrease in the trading price of our common shares.

 Any weaknesses identified in our system of internal controls by us and our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 could have an adverse effect on our business.

 Section 404 of the Sarbanes-Oxley Act of 2002 requires that public companies evaluate and report on their systems of internal control over financial reporting. In addition, our independent registered public accounting firm must report on management's evaluation of those controls. We may identify deficiencies in our system of internal controls over financial reporting that may require remediation. Any deficiencies or material weaknesses could result in significant time and expense to remediate, which could have a material adverse effect on our financial condition, results of operations and ability to make distributions to our shareholders.

 Item 1C. Cybersecurity.

 Risk Management and Strategy

 Ensuring the protection of sensitive data is fundamental to our operational integrity and strategic vision. Cybersecurity and data protection form essential pillars of our long-term strategy, safeguarding confidential information concerning our business, employees, customers, suppliers, and shareholders.

 Our corporate infrastructure, including information technology systems, communication networks, enterprise applications, and financial platforms, serves as vital tools for our business operations. These systems support crucial functions such as tenant and vendor management, internal communications, and financial record-keeping, underscoring the criticality of secure data collection, storage, and transmission.

 To mitigate material risks posed by cybersecurity threats to our critical networks, third-party services, and data assets, we have instituted a comprehensive suite of information security processes. These measures encompass the diligent identification, assessment, and management of potential risks, threat monitoring services, and vulnerability assessments.

 Our cybersecurity risk management strategy is underpinned by three key principles:

 •

 Cross-Functional Collaboration and Coordination: We foster collaboration among various departments, including our information security function, legal team, management, and third-party service providers, to effectively identify, assess, and manage cybersecurity risks.

 •

 Ongoing Evaluation and Assessment of Systems and Processes: We continuously evaluate and enhance our systems and processes to adapt to evolving cybersecurity threats, ensuring the resilience and effectiveness of our security measures.

 •

 Security Awareness Program: We conduct regular training and testing programs to enhance the cybersecurity awareness and readiness of our personnel, empowering them to actively contribute to our cybersecurity efforts.

 Additionally, we engage third-party providers to augment our cybersecurity capabilities. These partnerships entail ongoing assistance for threat monitoring and mitigation, as well as targeted support for specialized security expertise.

 As of December 31, 2023, we have not detected any cybersecurity threats, including prior incidents, that have materially impacted the Company, our business strategy, our financial results, or our financial health. For an examination of cybersecurity threats that could potentially have a material impact on us, please refer to our Risk Factors discussion in the section titled "We face risks relating to Cybersecurity attacks, loss of confidential information and other business disruptions" in this Form 10-K.

 Governance

 Aligned with our risk management governance structure, our management team oversees the daily management of cybersecurity risk, while our Board and its Audit Committee maintain an active and ongoing oversight role, with the Audit Committee receiving regular reports from management regarding cybersecurity risks and countermeasures being undertaken or considered, including updates to the internal and external cybersecurity landscape and relevant technical developments.

 Item 2. Properties.

 General

 As of December 31, 2023, we wholly-owned 55 commercial properties, including 12 properties in Houston, nine properties in Dallas-Fort Worth, three properties in San Antonio, five properties in Austin, and 26 properties in the Scottsdale and Phoenix, Arizona metropolitan areas.

 Our tenants consist of national, regional and local businesses. Our properties generally attract a mix of tenants who provide basic staples, convenience items and services tailored to the specific cultures, needs and preferences of the surrounding community. These types of tenants are the core of our strategy of creating Whitestone-branded Community Centered Properties. We also believe daily sales of basic items are less sensitive to fluctuations in the business cycle than higher priced retail items. Our largest tenant represented only 2.1% of our total revenues for the year ended December 31, 2023, and no single tenant exceeded 2.1%.

 Substantially all of our revenues consist of base rents received under leases that generally have terms that range from less than one year to 15 years. The following table summarizes certain information relating to our properties as of December 31, 2023:

 Our largest property, BLVD Place, a retail community purchased on May 26, 2017 and located in Houston, Texas, accounted for 10.5% of our total revenues for the year ended December 31, 2023. BLVD also accounted for 15.9% of our real estate assets, net of accumulated depreciation, for the year ended December 31, 2023.

 As of December 31, 2023, approximately $136.7 million of our total debt of $640.5 million was secured by five of our properties with a combined net book value of $212.3 million.

 Location of Properties

 Of our 55 wholly-owned properties, 12 are located in the greater Houston metropolitan statistical area. These properties represent 25% of our revenue for the year ended December 31, 2023. An additional 26 of our wholly-owned properties are located in the greater Phoenix metropolitan statistical area and represent 42% of our revenue for the year ended December 31, 2023.

 According to the United States Census Bureau, Houston and Phoenix ranked fifth and twelfth, respectively, in the largest United States metropolitan statistical areas as of December 31, 2023.

 Calculated as the tenant's actual December 31, 2023 base rent (defined as cash base rents including abatements) multiplied by 12. Excludes vacant space as of December 31, 2023. Because annualized base rental revenue is not derived from historical results that were accounted for in accordance with generally accepted accounting principles, historical results differ from the annualized amounts.

 Insurance

 We believe that we have property and liability insurance with reputable, commercially rated companies. We also believe that our insurance policies contain commercially reasonable deductibles and limits, adequate to cover our properties. We expect to maintain this type of insurance coverage and to obtain similar coverage with respect to any additional properties we acquire in the near future. Further, we have title insurance relating to our properties in an aggregate amount that we believe to be adequate.

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

 You should read the following discussion of our financial condition and results of operations in conjunction with our audited consolidated financial statements and the notes thereto included in this Annual Report on Form 10-K. For more detailed information regarding the basis of presentation for the following information, you should read the notes to our audited consolidated financial statements included in this Annual Report on Form 10-K.

 Overview of Our Company

 We are a fully integrated real estate company that owns and operates commercial properties in culturally diverse markets in major metropolitan areas. Founded in 1998, we are internally managed with a portfolio of commercial properties in Texas and Arizona.

 In October 2006, we adopted a strategic plan to acquire, redevelop, own and operate Community Centered Properties. We define Community Centered Properties as visibly located properties in established or developing culturally diverse neighborhoods in our target markets. We market, lease, and manage our centers to match tenants with the shared needs of the surrounding neighborhood. Those needs may include specialty retail, grocery, restaurants and medical, educational and financial services. Our goal is for each property to become a Whitestone-branded retail community that serves a neighboring five-mile radius around our property. We employ and develop a diverse group of associates who understand the needs of our multicultural communities and tenants.

 As of December 31, 2023, we wholly-owned 55 commercial properties consisting of:

 Consolidated Operating Portfolio

 •

 50 properties that meet our Community Centered Properties strategy; and containing approximately 5.0 million square feet of GLA and having a total carrying amount (net of accumulated depreciation) of $970.3 million; and

 Redevelopment, New Acquisitions Portfolio

 •

 five parcels of land held for future development that meet our Community Centered Properties strategy having a total carrying amount of $21.4 million.

 As of December 31, 2023, we had an aggregate of 1,453 tenants. We have a diversified tenant base with our largest tenant comprising only 2.1% of our total revenues for the year ended December 31, 2023. Lease terms for our properties range from less than one year for smaller tenants to more than 15 years for larger tenants. Our leases generally include minimum monthly lease payments and tenant reimbursements for taxes, insurance and maintenance. We completed 299 new and renewal leases during 2023, totaling 976,767 square feet and $118.9 million in total lease value.

 We had 79 employees as of December 31, 2023. As an internally managed REIT, we bear our own expenses of operations, including the salaries, benefits and other compensation of our employees, office expenses, legal, accounting and investor relations expenses and other overhead costs.

 Real Estate Partnership

 As of December 31, 2023, we, through our investment in Pillarstone OP, owned a majority interest in eight properties that do not meet our Community Centered Property strategy containing approximately 0.9 million square feet of GLA (the "Pillarstone Properties"). We own 81.4% of the total outstanding units of Pillarstone OP, which we account for using the equity method. We also managed the day-to-day operations of Pillarstone OP pursuant to a management agreement, which was terminated on August 18, 2022.

 Market Conditions

 Inflation

 We anticipate that the majority of our leases will continue to be triple-net leases or otherwise provide that tenants pay for increases in operating expenses and will contain provisions that we believe will mitigate the effect of inflation. In addition, many of our leases are for terms of less than five years, which allows us to adjust rental rates to reflect inflation and other changing market conditions when the leases expire. Consequently, increases due to inflation, as well as ad valorem tax rate increases, generally do not have a significant adverse effect upon our operating results.

 Rising Interest Rates

 As of December 31, 2023, $96.0 million, or approximately 15% of our outstanding debt, was subject to floating interest rates of SOFR plus 1.60% and a 10 basis point credit spread adjustment and not currently subject to a hedge. The impact of a 1% increase or decrease in interest rates on our non-hedged variable rate debt would result in a decrease or increase of annual net income of approximately $1.0 million, respectively.

 Refer to "Item 1A - Risk Factors" in this Annual Report on Form 10-K for additional information.

 How We Derive Our Revenue

 Substantially all of our revenue is derived from rents received from leases at our properties. We had total revenues of approximately $ 146,969,000 for the year ended December 31, 2023 as compared to $ 139,421,000 for the year ended December 31, 2022, an increase of $ 7,548,000, or 5%.

 Known Trends in Our Operations; Outlook for Future Results

 Rental Income

 We expect our rental income to increase year-over-year due to the addition of properties and rent increases on renewal leases. The amount of net rental income generated by our properties depends principally on our ability to maintain the occupancy rates of currently leased space and to lease currently available space, newly acquired properties with vacant space, and space available from unscheduled lease terminations. The amount of rental income we generate also depends on our ability to maintain or increase rental rates in our submarkets. Included in our adjustments to rental revenue for the years ending December 31, 2023 and 2022, were bad debt adjustments of $0.3 million and $0.6 million, respectively, and a straight-line rent reserve adjustments of $(0.002) million and $0.3 million, respectively, related to credit loss for the conversion of 20 and 80 tenants, respectively, to cash basis revenue as a result of collectability analysis.

 Scheduled Lease Expirations

 We tend to lease space to smaller businesses that desire shorter term leases. As of December 31, 2023, approximately 33% of our GLA was subject to leases that expire prior to December 31, 2025. Over the last three years, we have renewed expiring leases with respect to approximately 68% of our GLA. We routinely seek to renew leases with our existing tenants prior to their expiration and typically begin discussions with tenants as early as 18 months prior to the expiration date of the existing lease. Inasmuch as our early renewal program and other leasing and marketing efforts target these expiring leases, we hope to re-lease most of that space prior to expiration of the leases. In the markets in which we operate, we obtain and analyze market rental rates through review of third-party publications, which provide market and submarket rental rate data and through inquiry of property owners and property management companies as to rental rates being quoted at properties that are located in close proximity to our properties and we believe display similar physical attributes as our nearby properties. We use this data to negotiate leases with new tenants and renew leases with our existing tenants at rates we believe to be competitive in the markets for our individual properties. Due to the short term nature of our leases, and based upon our analysis of market rental rates, we believe that, in the aggregate, our current leases are at market rates. Market conditions, including new supply of properties, and macroeconomic conditions in our markets and nationally affecting tenant income, such as employment levels, business conditions, interest rates, tax rates, fuel and energy costs and other matters, could adversely impact our renewal rate and/or the rental rates we are able to negotiate. We continue to monitor our tenants' operating performances as well as overall economic trends to evaluate any future negative impact on our renewal rates and rental rates, which could adversely affect our cash flow and ability to make distributions to our shareholders.

 Property Acquisitions and Dispositions

 We seek to acquire commercial properties in high-growth markets. Our acquisition targets are properties that fit our Community Centered Properties strategy, primarily in and around Phoenix, Dallas-Fort Worth, San Antonio and Houston. We may acquire properties in other high growth cities in the future. We have extensive relationships with community banks, attorneys, title companies and others in the real estate industry, which we believe enables us to take advantage of these market opportunities and maintain an active acquisition pipeline. We market, lease and manage our centers to match tenants with the shared needs of the surrounding neighborhood. Those needs may include specialty retail, grocery and restaurants as well as medical, educational and financial services. Our goal is for each property to become a Whitestone-branded business center or retail community that serves a neighboring five-mile radius around our property.

 Property Acquisitions.

 On June 12, 2023, we acquired Arcadia Towne Center, a property that meets our Community Centered Property strategy, for $25.5 million in cash and net prorations. Arcadia Towne Center, a 69,503 square foot property, was 100% leased at the time of purchase and is located in Phoenix, Arizona.

 On December 21, 2022, we acquired Lake Woodlands Crossing, a property that meets our Community Centered Property strategy, for $22.5 million in cash and net prorations. Lake Woodlands Crossing, a 60,246 square foot property, was 89.3% leased at the time of purchase and is located in The Woodlands, Texas.

 On December 2, 2022 we acquired Dana Park Pad, a property that meets our Community Centered Property strategy, for $4.9 million in cash and net prorations. Dana Park Pad, a 12,000 square foot property, was 100% leased at the time of purchase and is located in the Mesa submarket of Phoenix, Arizona.

 Property Dispositions. We seek to continually upgrade our portfolio by opportunistically selling properties that do not have the potential to meet our Community Centered Property strategy and redeploying the sale proceeds into properties that better fit our strategy. Some of our properties that we own (the "non-core properties") may not fit our Community Centered Property strategy, and we may look for opportunities to dispose of these properties as we continue to execute our strategy.

 On December 8, 2016, we, through our Operating Partnership, entered into a Contribution Agreement (the "Contribution Agreement") with Pillarstone and Pillarstone REIT pursuant to which we contributed all of the equity interests in four of our wholly-owned subsidiaries that, at the time, owned 14 non-core properties (the "Pillarstone Properties") that did not fit our Community Centered Property strategy, to Pillarstone for aggregate consideration of approximately $84 million, consisting of (1) approximately $18.1 million of Class A units representing limited partnership interests in Pillarstone ("Pillarstone OP Units") and (2) the assumption of approximately $65.9 million of liabilities (collectively, the "Contribution").

 As of December 31, 2023, we owned approximately 81.4% of the total outstanding Pillarstone OP Units, which we account for under the equity method. See Note 4 Investment in Real Estate Partnership to the accompanying consolidated financial statements for more information on our accounting treatment of our investment in Pillarstone OP.

 Leasing Activity

 As of December 31, 2023, we wholly-owned 55 properties with 4,995,190 square feet of GLA, which were approximately 94% occupied. The following is a summary of the Company's leasing activity for the year ended December 31, 2023:

 Liquidity and Capital Resources

 Our short-term liquidity requirements consist primarily of distributions to holders of our common shares and OP units, including those required to maintain our REIT status and satisfy our current quarterly distribution target of $0.12 per share and OP unit, recurring expenditures, such as repairs and maintenance of our properties, non-recurring expenditures, such as capital improvements and tenant improvements, debt service requirements, and, potentially, acquisitions of additional properties.

 During the year ended December 31, 2023, our cash provided from operating activities was $47.6 million and our total dividends and distributions paid were $24.0 million. Therefore, we had cash flow from operations in excess of distributions of approximately $23.6 million. The 2022 Facility included a $250 million unsecured borrowing capacity under a revolving credit facility. The 2022 Facility also included an accordion feature that allowed the Operating Partnership to increase the borrowing capacity by $200 million, upon the satisfaction of certain conditions. We anticipate that cash flows from operating activities and our borrowing capacity under the 2022 Facility will provide adequate capital for our distributions, working capital requirements, anticipated capital expenditures and scheduled debt payments in the short term. We also believe that cash flows from operating activities and our borrowing capacity will allow us to make all distributions required for us to continue to qualify to be taxed as a REIT for federal income tax purposes.

 Our long-term capital requirements consist primarily of maturities under our longer-term debt agreements, development and redevelopment costs, and potential acquisitions. We expect to meet our long-term liquidity requirements with net cash from operations, long-term indebtedness, sales of common shares, issuance of OP units, sales of underperforming and non-core properties and other financing opportunities, including debt financing. We believe we have access to multiple sources of capital to fund our long-term liquidity requirements, including the incurrence of additional debt and the issuance of additional equity. However, our ability to incur additional debt will be dependent on a number of factors, including our degree of leverage, the value of our unencumbered assets and borrowing restrictions that may be imposed by lenders. As of December 31, 2023, subject to any potential future paydowns or increases in the borrowing base, we have $104.0 million remaining availability under the revolving credit facility.

 Our ability to access the capital markets will be dependent on a number of factors as well, including general market conditions for REITs and market perceptions about our Company. In light of the dynamics in the capital markets impacted by macro economic factors and economic uncertainty, our access to capital may be diminished. Despite these potential challenges, we believe we have sufficient access to capital for the foreseeable future, but we can provide no assurance that such capital will be available to us on attractive terms or at all.

 On May 20, 2022, our universal shelf registration statement on Form S-3 was declared effective by the SEC, which registers the issuance and sale by us of up to $500 million in securities from time to time, including common shares, preferred shares, debt securities, depositary shares and subscription rights.

 On September 9, 2022, we entered into eleven equity distribution agreements for an at-the-market equity distribution program (the "2022 equity distribution agreements") providing for the issuance and sale of up to an aggregate of $100 million of the Company's common shares pursuant to our Registration Statement on Form S-3 (File No. 333-264881). Actual sales will depend on a variety of factors determined by us from time to time, including (among others) market conditions, the trading price of our common shares, capital needs and our determinations of the appropriate sources of funding for us, and will be made in transactions that will be deemed to be "at-the-market" offerings as defined in Rule 415 under the Securities Act. We have no obligation to sell any of our common shares and can at any time suspend offers under the 2022 equity distribution agreements or terminate the 2022 equity distribution agreements. Net proceeds from common shares issued pursuant to the 2022 equity distribution agreements will be used for general corporate purposes, which may include acquisitions of additional properties, the repayment of outstanding indebtedness, capital expenditures, the expansion, redevelopment and/or re-tenanting of properties in our portfolio, working capital and other general purposes.

 We expect that our rental income will increase as we continue to acquire additional properties, subsequently increasing our cash flows generated from operating activities. We intend to finance the continued acquisition of such additional properties through equity issuances and through debt financing.

 Our capital structure includes non-recourse secured debt that we assumed or originated on certain properties. We may hedge the future cash flows of certain debt transactions principally through interest rate swaps with major financial institutions.

 As discussed in Note 2 to the accompanying consolidated financial statements, pursuant to the terms of our $15.1 million 4.99% Note, due January 6, 2024 (see Note 8 to the accompanying consolidated financial statements), which is collateralized by our Anthem Marketplace property, we were required by the lenders thereunder to establish a cash management account controlled by the lenders to collect all amounts generated by our Anthem Marketplace property in order to collateralize such promissory note. Amounts in the cash management account are classified as restricted cash.

 Cash and Cash Equivalents

 We had cash and cash equivalents and restricted cash of approximately $4,640,000 at December 31, 2023, as compared to $6,355,000 at December 31, 2022. The decrease of $1,715,000 was primarily the result of the following:

 Sources of Cash

 •

 Net proceeds from sale of properties of $19,847,000 for the year ended December 31, 2023 compared to $33,723,000 for the year ended December 31, 2022;

 •

 Cash flow from operations of $47,600,000 for the year ended December 31, 2023 compared to cash flow from operations of $44,431,000 for the year ended December 31, 2022;

 Uses of Cash

 •

 Acquisition of real estate of $25,474,000 compared to $16,992,000;

 •

 Acquisition of ground lease of $0 compared to $9,786,000;

 •

 Additions to real estate of $17,055,000 compared to $13,659,000;

 •

 Escrowed loan repayment on behalf of real estate partnership of $13,633,000 compared to $0.

 •

 Payment of dividends and distributions to common shareholders and OP unit holders of $24,016,000 compared to $23,304,000;

 •

 Payments of notes payable of $30,945,000 compared to $3,468,000;

 •

 Repurchase of common shares of $525,000 compared to $537,000;

 •

 Net (proceeds from) payment of credit facility of ($42,500,000) compared to $16,000,000;

 •

 Payment of loan originations cost of $0 compared to $3,632,000;

 •

 Payment of exchange offering cost of $0 compared to $335,000; and

 •

 Payment of finance lease liability of $14,000 compared to $0;

 We place all cash in short-term, highly liquid investments that we believe provide appropriate safety of principal.

 Promissory note includes an interest rate swap that fixed the SOFR portion of the term loan at an interest rate of 2.16% through October 28, 2022, 2.76% from October 29, 2022 through January 31, 2024, and 3.32% beginning February 1, 2024 through January 31, 2028.

 A portion of the unsecured line of credit includes an interest rate swap to fix the SOFR portion of the loan at 3.71%.

 On March 22, 2019, we, through our Operating Partnership, entered into a Note Purchase and Guarantee Agreement (the "Note Agreement") together with certain subsidiary guarantors as initial guarantor parties thereto (the "Subsidiary Guarantors") and The Prudential Insurance Company of America and the various other purchasers named therein (collectively, the "Purchasers") providing for the issuance and sale of $100 million of senior unsecured notes of the Operating Partnership, of which (i) $50 million are designated as 5.09% Series A Senior Notes due March 22, 2029 (the "Series A Notes") and (ii) $50 million are designated as 5.17% Series B Senior Notes due March 22, 2029 (the "Series B Notes" and, together with the Series A Notes, the "Notes") pursuant to a private placement that closed on March 22, 2019 (the "Private Placement"). Obligations under the Notes are unconditionally guaranteed by the Company and by the Subsidiary Guarantors.

 On December 16, 2022, Whitestone REIT (the "Company") and its operating partnership, Whitestone REIT Operating Partnership, L.P. (the "Operating Partnership"), amended its Note Purchase and Guarantee Agreement originally executed on March 22, 2019 (the "Existing Note Agreement"), pursuant to the terms and conditions of an Amendment No. 1 to Note Purchase and Guaranty Agreement, dated as of December 16, 2022 (the Existing Note Purchase Agreement, as so amended, the "Amended Note Agreement"), by and among the Company and the Operating Partnership, together with certain subsidiary guarantors as initial guarantor parties thereto and The Prudential Insurance Company of America and the various other purchasers named therein.

 Neither the term of the Existing Note Agreement, the interest rate, nor the principal amounts, were amended. The purpose of the amendment is to conform certain covenants and defined terms contained in the Amended Note Agreement with the Company's recently amended unsecured credit facility with the lenders party thereto, Bank of Montreal, as administrative agent, Truist Bank, as syndication agent, and BMO Capital Markets Corp., Truist Bank, Capital One, National Association, and U.S. Bank National Association, as co-lead arrangers and joint book runners.

 The principal of the Series A Notes began to amortize on March 22, 2023 with annual principal payments of approximately $7.1 million. The principal of the Series B Notes will begin to amortize on March 22, 2025 with annual principal payments of $10.0 million. The Notes will pay interest quarterly on the 22nd day of March, June, September and December in each year until maturity.

 The Operating Partnership may prepay at any time all, or from time to time part of, the Notes, in an amount not less than $1,000,000 in the case of a partial prepayment, at 100% of the principal amount so prepaid, plus a make-whole amount. The make-whole amount is equal to the excess, if any, of the discounted value of the remaining scheduled payments with respect to the Notes being prepaid over the aggregate principal amount of such Notes (as described in the Note Agreement). In addition, in connection with a Change of Control (as defined in the Note Purchase Agreement), the Operating Partnership is required to offer to prepay the Notes at 100% of the principal amount plus accrued and unpaid interest thereon.

 The Note Agreement contains representations, warranties, covenants, terms and conditions customary for transactions of this type and substantially similar to the Operating Partnership's existing senior revolving credit facility, including limitations on liens, incurrence of investments, acquisitions, loans and advances and restrictions on dividends and certain other restricted payments. In addition, the Note Agreement contains certain financial covenants substantially similar to the Operating Partnership's existing senior revolving credit facility, including the following:

 •

 maximum total indebtedness to total asset value ratio of 0.60 to 1.00;

 •

 maximum secured debt to total asset value ratio of 0.40 to 1.00;

 •

 minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges ratio of 1.50 to 1.00;

 •

 maximum secured recourse debt to total asset value ratio of 0.15 to 1.00;

 •

 maintenance of a minimum tangible net worth (adjusted for accumulated depreciation and amortization) of 75% of the Company's total net worth as of December 31, 2021 plus 75% of the net proceeds from additional equity offerings (as defined therein); and

 •

 minimum adjusted property NOI to implied unencumbered debt service ratio of 1.50 to 1.00.

 In addition, the Note Agreement contains a financial covenant requiring that maximum unsecured indebtedness not exceed the ratio of unsecured indebtedness to unencumbered asset pool of 0.60 to 1.00. That covenant is substantially similar to the borrowing base concept contained in the Operating Partnership's existing senior revolving credit facility.

 The Note Agreement also contains default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-performance of covenants, cross-defaults with other indebtedness and guarantor defaults. The occurrence of an event of default under the Note Agreement could result in the Purchasers accelerating the payment of all obligations under the Notes. The financial and restrictive covenants and default provisions in the Note Agreement are substantially similar to those contained in the Operating Partnership's existing credit facility.

 Net proceeds from the Private Placement were used to refinance existing indebtedness. The Notes have not been and will not be registered under the Securities Act of 1933, as amended (the "Securities Act"), and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act. The Notes were sold in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act.

 On September 16, 2022, we, through our Operating Partnership, entered into an unsecured credit facility (the "2022 Facility") with the lenders party thereto, Bank of Montreal, as administrative agent (the "Administrative Agent"), Truist Bank, as syndication agent, and BMO Capital Markets Corp., Truist Bank, Capital One, National Association, and U.S. Bank National Association, as co-lead arrangers and joint book runners. The 2022 Facility amended and restated the Company's previous unsecured revolving credit facility, dated January 31, 2019 (the "2019 Facility").

 The 2022 Facility is comprised of the following two tranches:

 •

 $250.0 million unsecured revolving credit facility with a maturity date of September 16, 2026 (the "2022 Revolver");

 •

 $265.0 million unsecured term loan with a maturity date of January 31, 2028 ("Term Loan").

 Borrowings under the 2022 Facility accrue interest (at the Operating Partnership's option) at a Base Rate or an Adjusted Term Secured Overnight Financing Rate ("SOFR") plus an applicable margin based upon our then existing leverage. As of December 31, 2023, the interest rate on the 2022 Revolver was 7.05%. Based on our current leverage ratio, the revolver has initial interest rate of SOFR plus 1.60% and a 10 basis point credit spread adjustment. In addition, we entered into interest rate swaps to fix the interest rates on the Term Loan. The Term Loan with the swaps has the following interest rates:

 •

 2.16% plus 1.55% through October 28, 2022

 •

 2.80% plus 1.55% from October 29, 2022 through January 31, 2024

 •

 3.42% plus 1.55% from February 1, 2024 through January 31, 2028

 The 2022 Facility also has a pricing provision where the applicable margin can be adjusted by an aggregate 0.02% per annum based on the Company's performance on certain sustainability performance targets. Base Rate means, for any day, the higher of: (a) the Administrative Agent's prime commercial rate, (b) the sum of (i) the rate per annum equal to the weighted average of the rates on overnight federal funds transactions with members of the Federal Reserve System, as published by the Federal Reserve Bank of New York for such day, plus (ii) 0.50%, or (c) the sum of (i) Adjusted Term SOFR for a one-month tenor in effect on such day plus (ii) 1.10%. Adjusted Term SOFR means, for any such day, the sum of (i) the SOFR-based term rate for the day two (2) business days prior and (ii) 0.10%.

 The 2022 Facility includes an accordion feature that will allow the Operating Partnership to increase the borrowing capacity by $200.0 million, upon the satisfaction of certain conditions. As of December 31, 2023, subject to any potential future paydowns or increases in the borrowing base, we have $104.0 million remaining availability under the 2022 Revolver. As of December 31, 2023, $411.0 million was drawn on the 2022 Facility and our unused borrowing capacity was $104.0 million, assuming that we use the proceeds of the 2022 Facility to acquire properties, or to repay debt on properties, that are eligible to be included in the unsecured borrowing base. The Company used $379.5 million of proceeds from the 2022 Facility to repay amounts outstanding under the 2019 Facility.

 The Company, each direct and indirect material subsidiary of the Operating Partnership and any other subsidiary of the Operating Partnership that is a guarantor under any unsecured ratable debt will serve as a guarantor for funds borrowed by the Operating Partnership under the 2022 Facility. The 2022 Facility contains customary terms and conditions, including, without limitation, customary representations and warranties and affirmative and negative covenants including, without limitation, information reporting requirements, limitations on investments, acquisitions, loans and advances, mergers, consolidations and sales, incurrence of liens, dividends and restricted payments. In addition, the 2022 Facility contains certain financial covenants including the following:

 •

 maximum total indebtedness to total asset value ratio of 0.60 to 1.00;

 •

 maximum secured debt to total asset value ratio of 0.40 to 1.00;

 •

 minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges ratio of 1.50 to 1.00;

 •

 maximum other recourse debt to total asset value ratio of 0.15 to 1.00; and

 •

 maintenance of a minimum tangible net worth (adjusted for accumulated depreciation and amortization) of $449 million plus 75% of the net proceeds from additional equity offerings (as defined therein).

 The 2022 Facility also contains customary events of default with customary notice and cure, including, without limitation, nonpayment, breach of covenant, misrepresentation of representations and warranties in a material respect, cross-default to other major indebtedness, change of control, bankruptcy and loss of REIT tax status. If an event of default occurs and is continuing under the 2022 Facility, the lenders may, among other things, terminate their commitments under the 2022 Facility and require the immediate payment of all amounts owed thereunder.

 As of December 31, 2023, our $136.7 million in secured debt was collateralized by five properties with a carrying value of $212.3 million. Our loans contain restrictions that would require the payment of prepayment penalties for the acceleration of outstanding debt and are secured by deeds of trust on certain of our properties and by assignment of the rents and leases associated with those properties. As of December 31, 2023, we were in compliance with all loan covenants.

 Capital Expenditures

 We continually evaluate our properties' performance and value. We may determine it is in our shareholders' best interest to invest capital in properties we believe have potential for increasing value. We also may have unexpected capital expenditures or improvements for our existing assets. Additionally, we intend to continue investing in similar properties outside of Texas and Arizona in cities with exceptional demographics to diversify market risk, and we may incur significant capital expenditures or make improvements in connection with any properties we may acquire.

 As of December 31, 2023, we had one loan totaling $96.0 million which bore interest at a floating rate. The variable interest rate payments are based on SOFR plus 1.60% and a 10 basis point spread adjustment which reflects our new interest rates under our 2022 Facility. The information in the table above reflects our projected interest rate obligations for the floating rate payments based on one-month SOFR as of December 31, 2023, of 5.40%.

 (2)

 The unused commitment fees on our unsecured credit facility, payable quarterly, are based on the average daily unused amount of our unsecured credit facility. The fees are 0.20% for facility usage greater than 50% or 0.25% for facility usage less than 50%. The information in the table above reflects our projected obligations for our unsecured credit facility based on our December 31, 2023 balance of $411.0 million.

 U.S. federal income tax law generally requires that a REIT distribute annually to its shareholders at least 90% of its REIT taxable income, without regard to the deduction for dividends paid and excluding net capital gains, and that it pay tax at regular corporate rates on any taxable income that it does not distribute. We currently, and intend to continue to, accrue distributions quarterly and make distributions in three monthly installments following the end of each quarter. For a discussion of our cash flow as compared to dividends, see "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources."

 The timing and frequency of our distributions are authorized and declared by our board of trustees in exercise of its business judgment based upon a number of factors, including:

 •

 Summary of Critical Accounting Policies and Estimates

 Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements. We prepared these financial statements in conformity with GAAP. The preparation of these financial statements required us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We based our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. Our results may differ from these estimates. For a better understanding of our accounting policies, you should read Note 2 to our accompanying consolidated financial statements in conjunction with this " Management ' s Discussion and Analysis of Financial Condition and Results of Operations."

 We have described below the critical accounting policies and estimates that we believe could impact our consolidated financial statements most significantly.

 Revenue Recognition. All leases on our properties are classified as operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases. Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon which they are based have been met. Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We combine lease and nonlease components in lease contracts, which includes combining base rent, recoveries, and percentage rents into a single line item, Rental, within the consolidated statements of operations and comprehensive income (loss). Additionally, we have tenants who pay real estate taxes directly to the taxing authority. We exclude these costs paid directly by the tenant to third parties on our behalf from revenue recognized and the associated property operating expense.

 Other property income primarily includes amounts recorded in connection with management fees and lease termination fees. Pillarstone OP paid us management fees for property management, leasing and day-to-day advisory and administrative services. Their obligations were satisfied over time. Pillarstone OP was billed monthly and typically paid quarterly. Revenues were governed by the Management Agreements (as defined in Note 4 to our accompanying consolidated financial statements). The management agreement was terminated on August 18, 2022. Additionally, we recognize lease termination fees in the year that the lease is terminated and collection of the fee is probable. Amounts recorded within other property income are accounted for at the point in time when control of the goods or services transfers to the customer and our performance obligation is satisfied.

 Estimates regarding Pillarstone OP ' s financial condition and results of operations and guarantee. We rely on the reports furnished by our third-party partners for financial information regarding the Company's investment in Pillarstone OP. As of December 31, 2023 and 2022, Pillarstone OP's financial statements have not been made accessible to us. Consequently, we have estimated the financial status and operational outcomes of Pillarstone OP based on the information accessible to us at the time of this report.

 The Company has a limited guarantee on Pillarstone OP's loan for its Uptown Tower property located in Dallas, Texas, with an aggregate principal amount of $14.4 million as of September 30, 2023. The guarantee is a so-called "bad boy" carve-out guarantee, which is generally only applicable if and when the borrower engages in acts such as fraud, prohibited transfers, breaches of material representations, environmental matters, and bankruptcy. The debt matured on October 4, 2023, and is currently in default, as Pillarstone OP failed to refinance the loan. The loan is also secured by the Uptown Tower property.

 On October 24, 2023, the Lender provided notice of a planned foreclosure sale on December 5, 2023. The Lender also claimed that an additional sum of $4.6 million was due which included default interest of approximately $6.3 million and net credits from escrowed funds and other charges of approximately $1.7 million. The default interest charges are in dispute, and we believe that the value of Uptown Tower exceeds the total amount claimed by the Lender.

 On December 1, 2023, the Company reached an agreement with the Lender that would avoid foreclosure and secure the release of the lien and discharge of the guarantee, and the Company negotiated and satisfied a payoff as of December 4, 2023, in the amount of $13,632,764 (the "DPO Amount"). We paid the DPO amount and will be entitled to assert a subrogation claim against Pillarstone OP. We recorded the DPO amount as an asset in our financial statement line escrows and deposits. We intend to pursue collection of amounts due from Pillarstone OP including the DPO amount and believe the amount will be in excess of the current carrying value of our equity investment in Pillarstone OP.

 The DPO Amount included a compromise settlement of approximately $1,688,000 for the disputed default interest and other fees. The Company's share of it was recorded in the 4th quarter of fiscal year 2023 in the financial statement line equity (deficit) in earnings of real estate partnership. Per the agreement, this payment would satisfy the Loan. The Company wired the DPO Amount to Lender on December 4, 2023, with accompanying releases as required by Lender, fully satisfying the agreement.

 On December 1, 2023, Pillarstone OP authorized and filed the Chapter 11 bankruptcy of its special purpose entity borrower that owns Uptown Tower (Whitestone Uptown Tower LLC) in Case No. 23-32832-mvl-11, in the United States Bankruptcy Court for the Northern District of Texas.

 On January 25, 2024, the Company exercised its notice of redemption for substantially all of its investment in Pillarstone OP.

 On February 9, 2024, the Lender filed suit in New York County, New York against the guarantor Whitestone OP and the Company for alleged amounts due under the guarantee. The compromise settlement is our best estimate of the amount due.

 On March 4, 2024, Pillarstone REIT authorized and filed the Chapter 11 bankruptcy of itself, Pillarstone OP, and the remainder of its special purpose entities in the United States Bankruptcy Court for the Northern District of Texas. As of the date of this filing, Whitestone has not received consideration for its redemption of its equity investment in Pillarstone OP as required by the partnership agreement. We intend to pursue collection of amounts due from Pillarstone OP through all means, including further litigation if necessary and while we do not know the ultimate amount to be collected, we believe the amount will be in excess of the current carrying value of our equity investment in Pillarstone OP.

 Equity Method. In accordance with Accounting Standards Update ("ASU") 2014-09 ("Topic 606") and Accounting Standards Codification ("ASC") 610, " Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets," the Company recognizes its investment in Pillarstone OP under the equity method.

 Development Properties. Land, buildings and improvements are recorded at cost. Expenditures related to the development of real estate are carried at cost which includes capitalized carrying charges and development costs. Carrying charges (interest, real estate taxes, loan fees, and direct and indirect development costs related to buildings under construction), are capitalized as part of construction in progress. The capitalization of such costs ceases when the property, or any completed portion, becomes available for occupancy. For the year ended December 31, 2023, approximately $ 552,000 and $ 262,000 in interest expense and real estate taxes, respectively, were capitalized. For the year ended December 31, 2022, approximately $455,000 and $281,000 in interest expense and real estate taxes, respectively, were capitalized. For the year ended December 31, 2021, approximately $414,000 and $291,000 in interest expense and real estate taxes, respectively, were capitalized.

 Acquired Properties and Acquired Lease Intangibles. We allocate the purchase price of the acquired properties to land, building and improvements, identifiable intangible assets and to the acquired liabilities based on their respective fair values at the time of purchase. Identifiable intangibles include amounts allocated to acquired out-of-market leases, the value of in-place leases, the value of the ground lease and customer relationship value, if any. We determine fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in our analysis of determining the as-if-vacant property value include an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt. The Company also utilizes valuations from independent real estate appraisal firms.

 Depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of 3 to 43 years for improvements and buildings. Tenant improvements are depreciated using the straight-line method over the life of the improvement or remaining term of the lease, whichever is shorter.

 Impairment. We review our properties and other long-lived assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. The first step of the impairment test is to determine whether an indicator of impairment is present. If an indicator of impairment is present, we determine whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property. If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. Management has determined that there has been no impairment in the carrying value of our real estate assets as of December 31, 2023.

 Accrued Rents and Accounts Receivable. Included in accrued rents and accounts receivable are base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant's payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. We recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue. As of December 31, 2023 and 2022, we had an allowance for uncollectible accounts of $13.6 million and $13.8 million, respectively. For the years ending December 31, 2023, 2022 and 2021, we recorded an adjustment to rental revenue in the amount of $1.0 million, $1.2 million and $(0.1) million, respectively. Included in the adjustment to rental revenue for the years ending December 31, 2023, 2022 and 2021, was a bad debt adjustment of $0.3 million, $0.6 million, and $0.1 million, respectively, and a straight-line rent reserve adjustment of $(0.002) million, $0.3 million, and $0.9 million, respectively, related to credit loss for the conversion of 20, 80, and 59 tenants, respectively.

 Unamortized Lease Commissions and Loan Costs. Leasing commissions are amortized using the straight-line method over the terms of the related lease agreements. Loan costs are amortized on the straight-line method over the terms of the loans, which approximates the interest method. Costs allocated to in-place leases whose terms differ from market terms related to acquired properties are amortized over the remaining life of the respective leases.

 Prepaids and Other Assets. Prepaids and other assets include escrows established pursuant to certain mortgage financing arrangements for real estate taxes and insurance and acquisition deposits which include earnest money deposits on future acquisitions.

 Federal Income Taxes. We elected to be taxed as a REIT under the Code beginning with our taxable year ended December 31, 1999. As a REIT, we generally are not subject to federal income tax on income that we distribute to our shareholders. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate rates. We believe that we are organized and operate in such a manner as to qualify to be taxed as a REIT, and we intend to operate so as to remain qualified as a REIT for federal income tax purposes.

 State Taxes. We are subject to the Texas Margin Tax which is computed by applying the applicable tax rate (1% for us) to the profit margin, which, generally, will be determined for us as total revenue less a 30% standard deduction. Although the Texas Margin Tax is not an income tax, Financial Accounting Standards Board ("FASB") ASC 740, " Income Taxes " ("ASC 740") applies to the Texas Margin Tax. As of December 31, 2023, 2022 and 2021, we recorded a margin tax provision of $0.5 million, $0.4 million and $0.4 million, respectively.

 Fair Value of Financial Instruments. Our financial instruments consist primarily of cash, cash equivalents, accounts receivable and accounts and notes payable. The carrying value of cash, cash equivalents, accounts receivable and accounts payable are representative of their respective fair values due to their short-term nature. The fair value of our long-term debt, consisting of fixed rate secured notes, variable rate secured notes and an unsecured revolving credit facility aggregate to approximately $612.4 million and $579.7 million as compared to the book value of approximately $640.5 million and $626.0 million as of December 31, 2023 and 2022, respectively. The fair value of our long-term debt is estimated on a Level 2 basis (as provided by ASC 820, " Fair Value Measurements and Disclosures "), using a discounted cash flow analysis based on the borrowing rates currently available to us for loans with similar terms and maturities, discounting the future contractual interest and principal payments.

 The fair value of our loan guarantee to Pillarstone OP is estimated on a Level 3 basis (as provided by ASC 820, " Fair Value Measurements and Disclosures "), using a probability-weighted discounted cash flow analysis based on a discount rate, discounting the loan balance. The fair value of the loan guarantee is $0 and $0.1 million as compared to the book value of approximately $0 and $0.1 million as of December 31, 2023 and 2022, respectively.

 Disclosure about fair value of financial instruments is based on pertinent information available to management as of December 31, 2023 and 2022. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since December 31, 2023, and current estimates of fair value may differ significantly from the amounts presented herein.

 Derivative Instruments and Hedging Activities. We utilize derivative financial instruments, principally interest rate swaps, to manage our exposure to fluctuations in interest rates. We have established policies and procedures for risk assessment, and the approval, reporting and monitoring of derivative financial instruments. We recognize our interest rate swaps as cash flow hedges with the effective portion of the changes in fair value recorded in comprehensive income (loss) and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. Any ineffective portion of a cash flow hedge's change in fair value is recorded immediately into earnings. Our cash flow hedges are determined using Level 2 inputs under ASC 820. Level 2 inputs represent quoted prices in active markets for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable. As of December 31, 2023, we consider our cash flow hedges to be highly effective.

 Recent Accounting Pronouncements. In March 2020, the FASB issued Accounting Standards Update No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04"), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate ("LIBOR") or by another reference rate expected to be discontinued because of reference rate reform. In January 2021, the FASB issued Accounting Standards Update No. 2021-01, "Reference Rate Reform (Topic 848): Scope" ("ASU 2021-01"), which clarified the scope and application of the original guidance. We have elected this option and adopted ASU 2020-04 and ASU 2021-01 effective September 2022. There was no material impact on the Company's consolidated financial statement as a result of adopting this guidance.

 We define "Non-Same Stores" as properties that have been acquired since the beginning of the period being compared and properties that have been sold, but not classified as discontinued operations. For purposes of comparing the twelve months ended December 31, 2023 to the twelve months ended December 31, 2022, Non-Same Stores include properties acquired between January 1, 2022 and December 31, 2023 and properties sold between January 1, 2022 and December 31, 2023, but not included in discontinued operations.

 (3)

 We define "Same Stores" as properties that have been owned during the entire period being compared. For purposes of comparing the twelve months ended December 31, 2023 to the twelve months ended December 31, 2022, Same Stores include properties owned before January 1, 2022 and not sold before December 31, 2023. Straight line rent adjustments, above/below market rents, and lease termination fees are excluded.

 Year Ended December 31, 2022 Compared to Year Ended December 31, 2021

 For a discussion and comparison of the results of our operations for the year ended December 31, 2022 with the year ended December 31, 2021, refer to "Management's Discussion and Analysis of Financial Conditions and Results of Operations" in our Form 10-K for the year ended December 31, 2022 filed with the SEC on March 8, 2023.

 Reconciliation of Non-GAAP Financial Measures

 Funds From Operations (NAREIT) ( " FFO ") and Core FFO

 The National Association of Real Estate Investment Trusts ("NAREIT") defines FFO as net income (loss) available to common shareholders computed in accordance with GAAP, excluding depreciation and amortization related to real estate, gains or losses from the sale of certain real estate assets, gains and losses from change in control, and impairment write-downs of certain real estate assets and investments in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity. We calculate FFO in a manner consistent with the NAREIT definition and also include adjustments for our unconsolidated real estate partnership.

 Core Funds from Operations ("Core FFO") is a non-GAAP measure. From time to time, we report or provide guidance with respect to "Core FFO" which removes the impact of certain non-recurring and non-operating transactions or other items we do not consider to be representative of our core operating results including, without limitation, default interest on debt of real estate partnership, extinguishment of debt cost, gains or losses associated with litigation involving the Company that is not in the normal course of business, and proxy contest professional fees.

 Management uses FFO as a supplemental measure to conduct and evaluate our business because there are certain limitations associated with using GAAP net income (loss) alone as the primary measure of our operating performance.

 Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time. Because real estate values instead have historically risen or fallen with market conditions, management believes that the presentation of operating results for real estate companies that use historical cost accounting is insufficient by itself. In addition, securities analysts, investors and other interested parties use FFO as the primary metric for comparing the relative performance of equity REITs.

 FFO and Core FFO should not be considered as an alternative to net income or other measurements under GAAP, as an indicator of our operating performance or to cash flows from operating, investing or financing activities as a measure of liquidity. FFO and Core FFO does not reflect working capital changes, cash expenditures for capital improvements or principal payments on indebtedness. Although our calculation of FFO is consistent with that of NAREIT, there can be no assurance that FFO and Core FFO presented by us is comparable to similarly titled measures of other REITs.

 Below are the calculations of FFO and Core FFO and the reconciliations to net income, which we believe is the most comparable GAAP financial measure (in thousands):

Because Pillarstone OP financial statements as of December 31, 2023 and 2022 have not been made available to us, we have estimated depreciation and amortization, loss (gain) on sale or disposal of properties or assets of real estate partnership, and default interest on debt of real estate partnership based on the information available to us at the time of this report.

 Property Net Operating Income ( " NOI ")

 NOI: Net Operating Income: Management believes that NOI is a useful measure of our property operating performance. We define NOI as operating revenues (rental and other revenues) less property and related expenses (property operation and maintenance and real estate taxes). Other REITs may use different methodologies for calculating NOI and, accordingly, our NOI may not be comparable to other REITs. Because NOI adjusts for general and administrative expenses, depreciation and amortization, equity in earnings of real estate partnership, interest expense, interest dividend and other investment income, provision for income taxes, gain or loss on sale of property from discontinued operations, management fee, net of related expenses, gain or loss on sale or disposal of assets, our pro rata share of NOI of equity method investments and net income attributable to noncontrolling interests, it provides a performance measure that, when compared year-over-year, reflects the revenues and expenses directly associated with owning and operating commercial real estate properties and the impact to operations from trends in occupancy rates, rental rates and operating costs, providing perspective not immediately apparent from net income. We use NOI to evaluate our operating performance since NOI allows us to evaluate the impact that factors such as occupancy levels, lease structure, lease rates and tenant base have on our results, margins and returns. In addition, management believes that NOI provides useful information to the investment community about our property and operating performance when compared to other REITs since NOI is generally recognized as a standard measure of property performance in the real estate industry. However, NOI should not be viewed as a measure of our overall financial performance since it does not reflect general and administrative expenses, depreciation and amortization, interest expense, interest income, provision for income taxes and gain or loss on sale or disposition of assets, the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties.

 Taxes

 We elected to be taxed as a REIT under the Code beginning with our taxable year ended December 31, 1999. As a REIT, we generally are not subject to federal income tax on income that we distribute to our shareholders. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate rates. We believe that we are organized and operate in a manner to qualify and be taxed as a REIT, and we intend to operate so as to remain qualified as a REIT for federal income tax purposes.

 Off-Balance Sheet Arrangements

 Guarantees We may guarantee the debt of a real estate partnership primarily because it allows the real estate partnership to obtain funding at a lower cost than could be obtained otherwise. This results in a higher return for the real estate partnership on its investment, and a higher return on our investment in the real estate partnership. We may receive a fee from the real estate partnership for providing the guarantee. Additionally, when we issue a guarantee, the terms of the real estate partnership's partnership agreement typically provide that we may receive indemnification from the real estate partnership or have the ability to increase our ownership interest. See Note 4 to the accompanying consolidated financial statements for information related to our guarantees of our real estate partnership's debt as of December 31, 2023 and 2022.

 Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

 Our future income, cash flows and fair value relevant to our financial instruments depend upon prevailing market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. Based upon the nature of our operations, we are not subject to foreign exchange rate or commodity price risk. The principal market risk to which we are exposed is the risk related to interest rate fluctuations. Many factors, including governmental monetary and tax policies, domestic and international economic and political considerations, and other factors that are beyond our control contribute to interest rate risk. Our interest rate risk objective is to limit the impact of interest rate fluctuations on earnings and cash flows and to lower our overall borrowing costs. To achieve this objective, we manage our exposure to fluctuations in market interest rates for our borrowings through the use of fixed rate debt instruments to the extent that reasonably favorable rates are obtainable.

 All of our financial instruments were entered into for other than trading purposes.

 Fixed Interest Rate Debt

 As of December 31, 2023, $544.5 million, or approximately 85%, of our outstanding debt was subject to fixed interest rates, which limit the risk of fluctuating interest rates. Though a change in the market interest rates affects the fair market value, it does not impact net income to shareholders or cash flows. Our total outstanding fixed interest rate debt has an average effective interest rate as of December 31, 2023 of approximately 4.70% per annum with expirations ranging from 2024 to 2029 (see Note 8 to our accompanying consolidated financial statements for further detail). Holding other variables constant, a 1% increase or decrease in interest rates would cause an $15.1 million decline or increase in the fair value for our fixed rate debt.

 Variable Interest Rate Debt

 As of December 31, 2023, $96.0 million, or approximately 15%, of our outstanding debt was subject to floating interest rates of SOFR plus 1.50% to 2.10% and not currently subject to a hedge. The impact of a 1% increase or decrease in interest rates on our floating rate debt would result in a decrease or increase, respectively, of annual net income of approximately $1.0 million.

 Item 9A. Controls and Procedures.

 Evaluation of Disclosure Controls and Procedures

 In connection with the preparation of this Annual Report on Form 10-K, as of December 31, 2023, an evaluation was performed under the supervision and with the participation of the Company's management, including our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rule 13a-15(e) under the Exchange Act. In performing this evaluation, management reviewed the selection, application and monitoring of our historical accounting policies. Based on that evaluation, the CEO and CFO concluded that as of December 31, 2023, these disclosure controls and procedures were effective and designed to ensure that the information required to be disclosed in our reports filed with the SEC is recorded, processed, summarized and reported on a timely basis. In designing and evaluating disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Management is required to apply judgment in evaluating the cost-benefit relationship of possible controls and procedures. We maintain disclosure controls and procedures that are designed to provide a reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow for timely decisions regarding required disclosure.

 Management ' s Annual Report on Internal Control Over Financial Reporting

 The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of its management, including its CEO and CFO, the Company conducted an evaluation of the effectiveness of its internal control over financial reporting based on the framework in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its evaluation under the framework in Internal Control - Integrated Framework (2013), the Company's management concluded that its internal control over financial reporting was effective as of December 31, 2023.

 The Company's independent registered public accounting firm has issued a report on the effectiveness of the Company's internal control over financial reporting, which appears on page F-4 of this Annual Report on Form 10-K.

 The Company's system of internal control over financial reporting was designed to provide reasonable assurance regarding the preparation and fair presentation of published financial statements in accordance with accounting principles generally accepted in the United States. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance and 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.

 Changes in Internal Control Over Financial Reporting

 There have been no significant changes in our internal control over financial reporting during the Company's quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting other than the remediation of material weakness discussed above.

 Item 9B. Other Information.

 During the fiscal quarter ended December 31, 2023, none of the Company's director of executive officers adopted, modified or terminated any contract, instruction or written plan for the purchase or sale of Company securities that was intended to satisfy the affirmative defense conditions of Rule 10b5 - 1 (c) or any "non-Rule 10b5 - 1 trading arrangement."

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 To the Board of Trustees and Shareholders of

 Whitestone REIT:

 Opinion on the Consolidated Financial Statements

 We have audited the accompanying consolidated balance sheets of Whitestone REIT and subsidiaries (the "Company") as of December 31, 2023 and 2022, and the related consolidated statements of operations and comprehensive income (loss), changes in equity, and cash flows for each of the years in the three year period ended December 31, 2023, and the related notes and financial statement schedules listed in the Index to Consolidated Financial Statements at Item 15 (collectively referred to as the "Consolidated Financial Statements"). In our opinion, the Consolidated Financial Statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three year period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

 We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"), and our report dated March 13, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.

 Basis for Opinion

 These Consolidated Financial Statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's Consolidated Financial Statements based on our audits. We are a public accounting firm registered with the 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 Consolidated Financial Statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the Consolidated Financial Statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the Consolidated 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 Consolidated Financial Statements. We believe that our audits provide a reasonable basis for our opinion.

 Critical Audit Matters

 The critical audit matters communicated below are matters arising from the current period audit of the Consolidated Financial Statements that were communicated or required to be communicated to the audit committee and that: (i) relate to accounts or disclosures that are material to the Consolidated Financial Statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the Consolidated Financial Statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

 Impairment Assessment of Investment in Real Estate Partnership

 As described in Note 2 to the Consolidated Financial Statements, management reviews properties and other long-lived assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. The first step of the impairment test is to determine whether an indicator of impairment is present. If an indicator of impairment is present, management determines if an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property. Actual results could differ from estimates supporting the Company's impairment analysis. If management's analysis indicates an impairment, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. As of December 31, 2023, the Company had approximately $32 million of investment in real estate partnership, with no impairment recognized for the year ended December 31, 2023.

 We identified management's impairment assessment as a critical audit matter primarily because of the significant estimates involved in management's impairment analysis, as these estimates resulted in audit procedures involving a high degree of auditor judgment and subjectivity and challenges in obtaining and evaluating audit evidence.

 Our testing procedures to address this critical audit matter included the following:

 •

 testing the design and operating effectiveness of the Company's internal control over financial reporting applicable to management's impairment assessment, including controls pertaining to management's estimates supporting the impairment analysis;

 •

 evaluating the methodology used by management in its impairment analysis;

 •

 evaluating market and fair value data used by management; and

 •

 evaluating the Company's assessment of the impact of subsequent events on the value of the Company's investment in real estate partnership.

 Impairment Assessment of Real Estate Assets

 As described in Note 2 to the Consolidated Financial Statements, management reviews properties and other long-lived assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. The first step of the impairment test is to determine whether an indicator of impairment is present. If an indicator of impairment is present, management determines if an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property. Actual results could differ from estimates supporting the Company's impairment analysis. If management's analysis indicates an impairment, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. As of December 31, 2023, the Company had approximately $1 billion in real estate assets, net of accumulated depreciation, with no impairment recognized for the year ended December 31, 2023.

 We identified management's impairment assessment as a critical audit matter primarily because of the significant estimates involved in management's impairment analysis, as these estimates resulted in audit procedures involving a high degree of auditor judgment and subjectivity and challenges in obtaining and evaluating audit evidence.

 Our testing procedures to address this critical audit matter included the following:

 •

 testing the design and operating effectiveness of the Company's internal control over financial reporting applicable to management's impairment assessment, including controls pertaining to management's estimates supporting the impairment analysis;

 •

 evaluating the methodology used by management in its impairment analysis;

 •

 evaluating the accuracy of occupancy rates used by management in its impairment analysis;

 •

 recalculating individual property net operating income using audited account balances;

 •

 evaluating inputs used for undiscounted cash flow assessment, including consideration of individual property net operating income, as discussed above;

 •

 evaluating management's analysis of market trends and identification of properties requiring further assessment; and

 •

 evaluating market and fair value data used by management.

 Acquisitions of Real Estate Assets

 As described in Note 2 to the Consolidated Financial Statements, management allocates the purchase price of acquired properties to land, buildings and improvements, identifiable intangible assets, and to be acquired liabilities based on respective fair values at the time of purchase. Management determines fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and specific market and economic conditions that may affect the property. During the year ended December 31, 2023, the Company acquired Arcadia Towne Center for $25.5 million in cash and net prorations.

 We identified acquisitions of real estate as a critical audit matter primarily because of the significant estimates involved in management's purchase price allocation, as these estimates resulted in audit procedures involving a high degree of auditor judgment and subjectivity and challenges in obtaining and evaluating audit evidence.

 Our testing procedures to address this critical audit matter included the following:

 •

 testing the design and operating effectiveness of the Company's internal control over financial reporting applicable to management's purchase price allocation, including controls pertaining to management's estimates supporting the purchase price allocation;

 •

 evaluating the methodology used by management in its purchase price allocation;

 •

 evaluating the consistency of the purchase price allocation with acquisition documents, payment transactions, and other supporting information; and

 •

 evaluating the use of a specialist for property valuation and purchase price allocation in accordance with AS 1105.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 To the Board of Trustees and Shareholders of

 Whitestone REIT:

 Opinion on Internal Control over Financial Reporting

 We have audited Whitestone REIT and subsidiaries' (the "Company's") internal control over financial reporting as of December 31, 2023, 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 Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control—Integrated Framework (2013) issued by COSO.

 We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the consolidated balance sheets and the related consolidated statements of operations and comprehensive income (loss), changes in equity, and cash flows of the Company, and our report dated March 13, 2024, expressed an unqualified opinion.

 Basis for Opinion

 The Company's management is responsible 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 appearing under Item 9A. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. 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 audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

 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.

 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.

 1. DESCRIPTION OF BUSINESS AND NATURE OF OPERATIONS

 Whitestone REIT ("Whitestone") was formed as a real estate investment trust, pursuant to the Texas Real Estate Investment Trust Act on August 20, 1998. In July 2004, we changed our state of organization from Texas to Maryland pursuant to a merger where we merged directly with and into a Maryland real estate investment trust formed for the sole purpose of the reorganization and the conversion of each of our outstanding common shares of beneficial interest of the Texas entity into 1.42857 common shares of beneficial interest of the Maryland entity. We serve as the general partner of Whitestone REIT Operating Partnership, L.P. (the "Operating Partnership" or "WROP" or "OP"), which was formed on December 31, 1998 as a Delaware limited partnership. We currently conduct substantially all of our operations and activities through the Operating Partnership. As the general partner of the Operating Partnership, we have the exclusive power to manage and conduct the business of the Operating Partnership, subject to certain customary exceptions. As of December 31, 2023, 2022 and 2021, we owned 55, 57, and 60 commercial properties, respectively, in and around Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio.

 As of December 31, 2023, these properties consist of:

 Consolidated Operating Portfolio

 •

 50 wholly-owned properties that meet our Community Centered Properties strategy; and

 Redevelopment, New Acquisitions Portfolio

 •

 five parcels of land held for future development.

 As of December 31, 2023, we, through our equity-method investment in Pillarstone Capital REIT Operating Partnership LP ("Pillarstone" or "Pillarstone OP"), owned a majority interest in eight properties that do not meet our Community Centered Property strategy containing approximately 0.9 million square feet of GLA (the "Pillarstone Properties"). We own 81.4 % of the total outstanding units of Pillarstone OP, which we account for using the equity method. We also managed the day-to-day operations of Pillarstone OP pursuant to a management agreement, which was terminated on August 18, 2022.

 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND ESTIMATES

 Basis of Consolidation. We are the sole general partner of the Operating Partnership and possess full legal control and authority over the operations of the Operating Partnership. As of December 31, 2023, 2022 and 2021, we owned a majority of the partnership interests in the Operating Partnership. Consequently, the accompanying consolidated financial statements include the accounts of the Operating Partnership.

 Noncontrolling interest in the accompanying consolidated financial statements represents the share of equity and earnings of the Operating Partnership allocable to holders of operating partnership interests other than us. Net income or loss is allocated to noncontrolling interests based on the weighted-average percentage ownership of the Operating Partnership during the year. Issuance of additional common shares of beneficial interest in Whitestone (the "common shares") and units of limited partnership interest in the Operating Partnership that are convertible into cash or, at our option, common shares on a one -for- one basis (the "OP units") changes the percentage of ownership interests of both the noncontrolling interests and Whitestone.

 F-

 Estimates regarding Pillarstone OP ' s financial condition and results of operations and guarantee. We rely on the reports furnished by our third -party partners for financial information regarding the Company's investment in Pillarstone OP. As of December 31, 2023 and 2022, Pillarstone OP's financial statements have not been made accessible to us. Consequently, we have estimated the financial status and operational outcomes of Pillarstone OP based on the information accessible to us at the time of this report.

 The Company has a limited guarantee on Pillarstone OP's loan for its Uptown Tower property located in Dallas, Texas, with an aggregate principal amount of $ 14.4 million as of September 30, 2023. The guarantee is a so-called "bad boy" carve-out guarantee, which is generally only applicable if and when the borrower engages in acts such as fraud, prohibited transfers, breaches of material representations, environmental matters, and bankruptcy. The debt matured on October 4, 2023, and is currently in default, as Pillarstone OP failed to refinance the loan. The loan is also secured by the Uptown Tower property.

 On October 24, 2023, the Lender provided notice of a planned foreclosure sale on December 5, 2023. The Lender also claimed that an additional sum of $ 4.6 million was due which included default interest of approximately $ 6.3 million and net credits from escrowed funds and other charges of approximately $ 1.7 million. The default interest charges are in dispute, and we believe that the value of Uptown Tower exceeds the total amount claimed by the Lender.

 On December 1, 2023, the Company reached an agreement with the Lender that would avoid foreclosure and secure the release of the lien and discharge of the guarantee, and the Company negotiated and satisfied a payoff as of December 4, 2023, in the amount of $ 13,632,764 (the "DPO Amount"). We paid the DPO amount and will be entitled to assert a subrogation claim against Pillarstone OP. We recorded the DPO amount as an asset in our financial statement line escrows and deposits. We intend to pursue collection of amounts due from Pillarstone OP including the DPO amount and believe the amount will be in excess of the current carrying value of our equity investment in Pillarstone OP.

 The DPO Amount included a compromise settlement of approximately $ 1,688,000 for the disputed default interest and other fees. The Company's share of it was recorded in the 4th quarter of fiscal year 2023 in the financial statement line equity (deficit) in earnings of real estate partnership. Per the agreement, this payment would satisfy the Loan. The Company wired the DPO Amount to Lender on December 4, 2023, with accompanying releases as required by Lender, fully satisfying the agreement.

 On December 1, 2023, Pillarstone OP authorized and filed the Chapter 11 bankruptcy of its special purpose entity borrower that owns Uptown Tower (Whitestone Uptown Tower LLC) in Case No. 23 - 32832 -mvl- 11, in the United States Bankruptcy Court for the Northern District of Texas.

 On January 25, 2024, the Company exercised its notice of redemption for substantially all of its investment in Pillarstone OP.

 On February 9, 2024, the Lender filed suit in New York County, New York against the guarantor Whitestone OP and the Company for alleged amounts due under the guarantee. The compromise settlement is our best estimate of the amount due.

 On March 4, 2024, Pillarstone REIT authorized and filed the Chapter 11 bankruptcy of itself, Pillarstone OP, and the remainder of its special purpose entities in the United States Bankruptcy Court for the Northern District of Texas. As of the date of this filing, Whitestone has not received consideration for its redemption of its equity investment in Pillarstone OP as required by the partnership agreement. We intend to pursue collection of amounts due from Pillarstone OP through all means, including further litigation if necessary and while we do not know the ultimate amount to be collected, we believe the amount will be in excess of the current carrying value of our equity investment in Pillarstone OP.

 Equity Method. In accordance with Accounting Standards Update ("ASU") 2014 - 09 ("Topic 606") and Accounting Standards Codification "ASC" 610, " Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets," the Company recognizes its investment in Pillarstone OP under the equity method.

 As of December 31, 2023, we, through our investment in Pillarstone OP, owned a majority interest in eight properties that do not meet our Community Centered Property strategy containing approximately 0.9 million square feet of GLA. We own 81.4 % of the total outstanding units of Pillarstone OP. We also managed the day-to-day operations of Pillarstone OP pursuant to a management agreement, which was terminated on August 18, 2022. In this Annual Report on Form 10 -K, unless otherwise indicated, we do not include the Pillarstone Properties when we refer to our properties.

 Basis of Accounting. Our financial records are maintained on the accrual basis of accounting whereby revenues are recognized when earned and expenses are recorded when incurred.

 Use of Estimates. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates that we use include the estimated fair values of properties acquired, the estimated useful lives for depreciable and amortizable assets and costs, the grant date fair value of common share units included in share-based compensation expense, the estimated allowance for doubtful accounts, the estimated fair value of interest rate swaps, the estimates supporting our impairment analysis for the carrying values of our real estate assets and the estimates made regarding Pillarstone REIT Operating Partnership LP's financial condition and results of operations. Actual results could differ from those estimates.

 Reclassifications. We have reclassified certain prior year amounts in the accompanying consolidated financial statements in order to be consistent with the current fiscal year presentation. These reclassifications had no effect on net income, total assets, total liabilities or equity.

 Restricted Cash. We classify all cash pledged as collateral to secure certain obligations and all cash whose use is limited as restricted cash. During 2015, pursuant to the terms of our $ 15.1 million 4.99 % Note, due January 6, 2024, which is collateralized by our Anthem Marketplace property, we were required by the lenders thereunder to establish a cash management account controlled by the lenders to collect all amounts generated by our Anthem Marketplace property in order to collateralize such promissory note.

 Share-Based Compensation. From time to time, we award nonvested restricted common share awards or restricted common share unit awards, which may be converted into common shares, to executive officers and employees under our 2018 Long-Term Equity Incentive Ownership Plan (the "2018 Plan"). Awarded shares and units vest when certain performance conditions are met. We recognize compensation expense when achievement of the performance conditions is probable based on management's most recent estimates using the fair value of the shares as of the grant date. We recognized $ 3.7 million, $ 1.5 million and $ 5.9 million in share-based compensation expense for the years ended December 31, 2023, 2022 and 2021, respectively.

 F-

 Noncontrolling Interests. Noncontrolling interests are the portion of equity in a subsidiary not attributable to a parent. The ownership interests not held by the parent are considered noncontrolling interests. Accordingly, we have reported noncontrolling interests in equity on the consolidated balance sheets but separate from Whitestone's equity. On the consolidated statements of operations and comprehensive income (loss), subsidiaries are reported at the consolidated amount, including both the amount attributable to Whitestone and noncontrolling interests. Consolidated statements of changes in equity are included for both quarterly and annual financial statements, including beginning balances, activity for the period and ending balances for shareholders' equity, noncontrolling interests and total equity.

 Revenue Recognition. All leases on our properties are classified as operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases. Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon which they are based have been met. Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We combine lease and nonlease components in lease contracts, which includes combining base rent, recoveries, and percentage rents into a single line item, Rental, within the consolidated statements of operations and comprehensive income (loss). Additionally, we have tenants who pay real estate taxes directly to the taxing authority. We exclude these costs paid directly by the tenant to third parties on our behalf from revenue recognized and the associated property operating expense.

 Other property income primarily includes amounts recorded in connection with management fees and lease termination fees. Pillarstone OP paid us management fees for property management, leasing and day-to-day advisory and administrative services. The management agreement with Pillarstone OP was terminated on August 18, 2022. Additionally, we recognize lease termination fees in the year that the lease is terminated and collection of the fee is probable. Amounts recorded within other property income are accounted for at the point in time when control of the goods or services transfers to the customer and our performance obligation is satisfied.

 Cash and Cash Equivalents. We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents as of December 31, 2023 and 2022 consisted of demand deposits at commercial banks and brokerage accounts. We may have net book credit balances in our primary disbursement accounts at the end of a reporting period. We classify such credit balances as accounts payable in our consolidated balance sheets as checks presented for payment to these accounts are not payable by our banks under overdraft arrangements, and, therefore, do not represent short-term borrowings.

 Real Estate

 Development Properties. Land, buildings and improvements are recorded at cost. Expenditures related to the development of real estate are carried at cost which includes capitalized carrying charges and development costs. Carrying charges (interest, real estate taxes, loan fees, and direct and indirect development costs related to buildings under construction) are capitalized as part of construction in progress. The capitalization of such costs ceases when the property, or any completed portion, becomes available for occupancy. For the year ended December 31, 2023, approximately $ 552,000 and $ 262,000 in interest expense and real estate taxes, respectively, were capitalized. For the year ended December 31, 2022, approximately $ 455,000 and $ 281,000 in interest expense and real estate taxes, respectively, were capitalized. For the year ended December 31, 2021, approximately $ 414,000 and $ 291,000 in interest expense and real estate taxes, respectively, were capitalized.

 F-

 Acquired Properties and Acquired Lease Intangibles. We allocate the purchase price of the acquired properties to land, building and improvements, identifiable intangible assets and to the acquired liabilities based on their respective fair values at the time of purchase. Identifiable intangibles include amounts allocated to acquired out-of-market leases, the value of in-place leases, the value of the ground lease and customer relationship value, if any. We determine fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in our analysis of determining the as-if-vacant property value include an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt. The Company also utilizes valuations from independent real estate appraisal firms.

 Depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of 3 to 43 years for improvements and buildings. Tenant improvements are depreciated using the straight-line method over the life of the improvement or remaining term of the lease, whichever is shorter.

 Impairment. We review our properties and other long-lived assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. The first step of the impairment test is to determine whether an indicator of impairment is present. If an indicator of impairment is present, we determine whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property. If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. Management has determined that there has been no impairment in the carrying value of our real estate assets as of December 31, 2023.

 Accrued Rents and Accounts Receivable. Included in accrued rents and accounts receivable are base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant's payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. We recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue. As of December 31, 2023 and 2022, we had an allowance for uncollectible accounts of $ 13.6 million and $ 13.8 million, respectively. For the years ending December 31, 2023, 2022 and 2021, we recorded an adjustment to rental revenue in the amount of $ 1.0 million, $ 1.2 million and $( 0.1) million, respectively. Included in the adjustment to rental revenue for the years ending December 31, 2023, 2022 and 2021, was a bad debt adjustment of $ 0.3 million, $ 0.6 million, and $ 0.1 million, respectively, and a straight-line rent reserve adjustment of $( 0.002) million, $ 0.3 million, $ 0.9 million, respectively, related to credit loss for the conversion of 20, 80, and 59 tenants, respectively.

 Unamortized Lease Commissions and Loan Costs. Leasing commissions are amortized using the straight-line method over the terms of the related lease agreements. Loan costs are amortized on the straight-line method over the terms of the loans, which approximates the interest method. Costs allocated to in-place leases whose terms differ from market terms related to acquired properties are amortized over the remaining life of the respective leases.

 Prepaids and Other Assets. Prepaids and other assets include escrows established pursuant to certain mortgage financing arrangements for real estate taxes and insurance and acquisition deposits which include earnest money deposits on future acquisitions.

 Federal Income Taxes. We elected to be taxed as a REIT under the Code beginning with our taxable year ended December 31, 1999. As a REIT, we generally are not subject to federal income tax on income that we distribute to our shareholders. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate rates. We believe that we are organized and operate in such a manner as to qualify to be taxed as a REIT, and we intend to operate so as to remain qualified as a REIT for federal income tax purposes.

 F-

 State Taxes. We are subject to the Texas Margin Tax, which is computed by applying the applicable tax rate ( 1 % for us) to the profit margin, which, generally, will be determined for us as total revenue less a 30 % standard deduction. Although the Texas Margin Tax is not considered an income tax, Financial Accounting Standards Board ("FASB") ASC 740, " Income Taxes " ("ASC 740") applies to the Texas Margin Tax. As of December 31, 2023, 2022 and 2021, we recorded a margin tax provision of $ 0.5 million, $ 0.4 million and $ 0.4 million, respectively.

 Fair Value of Financial Instruments. Our financial instruments consist primarily of cash, cash equivalents, accounts receivable and accounts and notes payable. The carrying value of cash, cash equivalents, accounts receivable and accounts payable are representative of their respective fair values due to their short-term nature. The fair value of our long-term debt, consisting of fixed rate secured notes, variable rate secured notes and an unsecured revolving credit facility aggregate to approximately $ 612.4 million and $ 579.7 million as compared to the book value of approximately $ 640.5 million and $ 626.0 million as of December 31, 2023 and 2022, respectively. The fair value of our long-term debt is estimated on a Level 2 basis (as provided by ASC 820, " Fair Value Measurements and Disclosures " ("ASC 820")), using a discounted cash flow analysis based on the borrowing rates currently available to us for loans with similar terms and maturities, discounting the future contractual interest and principal payments.

 The fair value of our loan guarantee to Pillarstone OP is estimated on a Level 3 basis (as provided by ASC 820), using a probability-weighted discounted cash flow analysis based on a discount rate, discounting the loan balance. The fair value of the loan guarantee is $ 0 and $ 0.1 million as compared to the book value of approximately $ 0 and $ 0.1 million as of December 31, 2023 and 2022, respectively.

 Disclosure about fair value of financial instruments is based on pertinent information available to management as of December 31, 2023 and 2022. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since December 31, 2023, and current estimates of fair value may differ significantly from the amounts presented herein.

 Derivative Instruments and Hedging Activities. We utilize derivative financial instruments, principally interest rate swaps, to manage our exposure to fluctuations in interest rates. We have established policies and procedures for risk assessment, and the approval, reporting and monitoring of derivative financial instruments. We recognize our interest rate swaps as cash flow hedges with the effective portion of the changes in fair value recorded in comprehensive income (loss) and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. Any ineffective portion of a cash flow hedge's change in fair value is recorded immediately into earnings. Our cash flow hedges are determined using Level 2 inputs under ASC 820. Level 2 inputs represent quoted prices in active markets for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable. As of December 31, 2023, we consider our cash flow hedges to be highly effective.

 Concentration of Risk. Substantially all of our revenues are obtained from office and retail locations in the Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio metropolitan areas. We maintain cash accounts in major U.S. financial institutions. The terms of these deposits are on demand to minimize risk. The balances of these accounts sometimes exceed the federally insured limits, although no losses have been incurred in connection with these deposits.

 Recent Accounting Pronouncements. In March 2020, the FASB issued ASU No. 2020 - 04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020 - 04"), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate ("LIBOR") or by another reference rate expected to be discontinued because of reference rate reform. In January 2021, the FASB issued Accounting Standards Update No. 2021 - 01, "Reference Rate Reform (Topic 848): Scope" ("ASU 2021 - 01"), which clarified the scope and application of the original guidance. We have elected this option and adopted ASU 2020 - 04 and ASU 2021 - 01 effective September 2022. There was no material impact on the Company's consolidated financial statement as a result of adopting this guidance.

 4. INVESTMENT IN REAL ESTATE PARTNERSHIP

 On December 8, 2016, we, through our Operating Partnership, entered into a Contribution Agreement (the "Contribution Agreement") with Pillarstone OP and Pillarstone Capital REIT ("Pillarstone REIT") pursuant to which we contributed all of the equity interests in four of our wholly-owned subsidiaries that, at the time, owned 14 non-core properties that did not fit our Community Centered Property strategy (the "Pillarstone Properties"), to Pillarstone OP for aggregate consideration of approximately $ 84 million, consisting of ( 1) approximately $ 18.1 million of Class A units representing limited partnership interests in Pillarstone OP ("Pillarstone OP Units") and ( 2) the assumption of approximately $ 65.9 million of liabilities (collectively, the "Contribution").

 In connection with the Contribution, Whitestone TRS, Inc., a subsidiary of the Company ("Whitestone TRS"), entered into a management agreement with the entities that own the contributed Pillarstone Properties (collectively, the "Management Agreements"). Pursuant to the Management Agreements, Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services. The management agreement was terminated on August 18, 2022. Prior to the termination of the Management Agreement, we reported approximately $ 144,000 in property management fee income on a quarterly basis.

 F-

 In connection with the Contribution, on December 8, 2016, the Operating Partnership entered into a Tax Protection Agreement with Pillarstone REIT and Pillarstone OP pursuant to which Pillarstone OP agreed to indemnify the Operating Partnership for certain tax liabilities resulting from its recognition of income or gain prior to December 8, 2021 if such liabilities result from a transaction involving a direct or indirect taxable disposition of all or a portion of the Pillarstone Properties or if Pillarstone OP fails to maintain and allocate to the Operating Partnership for taxation purposes minimum levels of liabilities as specified in the Tax Protection Agreement, the result of which causes such recognition of income or gain and the Company incurs taxes that must be paid to maintain its REIT status for federal income tax purposes.

 As of December 31, 2023, we owned approximately 81.4 % of the total outstanding units of Pillarstone OP.

 In accordance with ASU 2014 - 09 ("Topic 606") and ASC 610, " Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets," the Company recognizes its investment in Pillarstone OP under the equity method.

 On December 26, 2021, the Board of Trustees of Pillarstone REIT adopted a new shareholder rights agreement (the "Pillarstone Rights Agreement"). Because Pillarstone REIT sought to use the Pillarstone Rights Agreement to prevent Whitestone OP from exercising its contractual Redemption Right, on July 12, 2022, Whitestone OP filed suit against Pillarstone REIT in the Court of Chancery of the State of Delaware challenging the Pillarstone Rights Agreement. On September 8, 2022, Whitestone OP's Motion to Preserve the Status Quo was granted by the Court, limiting Pillarstone OP from engaging in any acts outside the ordinary course of business and otherwise imposing restrictions on Pillarstone OP to ensure that Whitestone's right of redemption is not impaired while the underlying dispute is being considered by the Court. On January 25, 2024, the Delaware Court of Chancery: held that Pillarstone breached the implied covenant of good faith and fair dealing when it adopted the Pillarstone Rights Agreement that thwarted Whitestone OP from exercising the unfettered contractual redemption right it obtained in connection with its investment in the partnership; and the Court held that the Rights Plan was unenforceable as to the limited partner and allowed Whitestone OP to exercise its redemption right; allowed Pillarstone to determine the current value of the Partnership's assets; and, as necessary, later enter a monetary judgment against Pillarstone for the difference between the amount Whitestone would have received in or around December 2021 and the current value. On January 25, 2024, the Company exercised its notice of redemption for substantially all of its investment in Pillarstone OP. On March 4, 2024, Pillarstone REIT authorized and filed the Chapter 11 bankruptcy of itself, Pillarstone OP, and the remainder of its special purpose entities in the United States Bankruptcy Court for the Northern District of Texas. As of the date of this filing, Whitestone has not received consideration for its redemption of its equity investment in Pillarstone OP as required by the partnership agreement. We intend to pursue collection of amounts due from Pillarstone OP through all means, including further litigation if necessary and while we do not know the ultimate amount to be collected, we believe the amount will be in excess of the current carrying value of our equity investment in Pillarstone OP.

 We rely on reporting provided to us by our third -party partners for financial information regarding the Company's investment in Pillarstone OP. Because Pillarstone OP financial statements as of December 31, 2023 and 2022 have not been made available to us, we have estimated net income and its components based on the information available to us at the time of this report.

 The amortization of the basis difference between the cost of investment and the Company's share of underlying net book value for all three years ended December 31, 2023, 2022 and 2021 was $ 108,000. The Company amortized the difference into equity in earnings of real estate partnership on the consolidated statements of operations and comprehensive income (loss).

 The Company's maximum exposure to loss relating to Pillarstone OP is limited to its investment in Pillarstone OP and its guarantee of promissory notes issued to Pillarstone OP. Please refer to Note 16 of this 10 -K report for additional information.

 The Company has evaluated its guarantee to Pillarstone OP pursuant to ASC 460, Guarantees, and has determined the guarantee to be a performance guarantee, for which ASC 460 contains initial recognition and measurement requirements, and related disclosure requirements. The Company is obligated in two respects: (i) a noncontingent liability, which represents the Company's obligation to stand ready to perform under the terms of the guarantee in the event that the specified triggering event(s) occur; and (ii) the contingent liability, which represents the Company's obligation to make future payments if those triggering events occur. The Company recognized a noncontingent liability of $ 462,000 at the inception of the guarantee at fair value and is recorded on the Company's consolidated balance sheet as a liability. The Company amortizes the guarantee liability into income over seven years. For the years ended December 31, 2023, 2022, and 2021, the amortization of the guarantee liability was $ 18,000, $ 37,000, and $ 38,000, respectively.

 7. LEASES

 As a Lessor. All leases on our properties are classified as noncancelable operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases. Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon which they are based have been met. Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We combine lease and nonlease components in lease contracts, which includes combining base rent, recoveries, and percentage rents into a single line item, Rental, within the consolidated statements of operations and comprehensive income (loss).

 A summary of minimum future rents to be received (exclusive of renewals, tenant reimbursements, contingent rents, and collectability adjustments under Topic 842) under noncancelable operating leases in existence as of December 31, 2023 is as follows (in thousands):

 As of December 31, 2023, the Company had one ground lease with the lease term of 98 years. The lease is classified as a finance lease. The ground lease provides for variable rental payments based on CPI adjustment.

 The following table summarizes the fixed, future minimum rental payments, excluding variable costs, which are discounted by our weighted average incremental borrowing rates to calculate the lease liabilities for our operating and finance leases in existence as of December 31, 2023 in which we are the lessee (in thousands):

 On March 22, 2019, we, through our Operating Partnership, entered into a Note Purchase and Guarantee Agreement (the "Note Agreement") together with certain subsidiary guarantors as initial guarantor parties thereto (the "Subsidiary Guarantors") and The Prudential Insurance Company of America and the various other purchasers named therein (collectively, the "Purchasers") providing for the issuance and sale of $ 100 million of senior unsecured notes of the Operating Partnership, of which (i) $ 50 million are designated as 5.09 % Series A Senior Notes due March 22, 2029 ( the "Series A Notes") and (ii) $ 50 million are designated as 5.17 % Series B Senior Notes due March 22, 2029 ( the "Series B Notes" and, together with the Series A Notes, the "Notes") pursuant to a private placement that closed on March 22, 2019 ( the "Private Placement"). Obligations under the Notes are unconditionally guaranteed by the Company and by the Subsidiary Guarantors.

 On December 16, 2022, Whitestone REIT (the "Company") and its operating partnership, Whitestone REIT Operating Partnership, L.P. (the "Operating Partnership"), amended its Note Purchase and Guarantee Agreement originally executed on March 22, 2019 ( the "Existing Note Agreement"), pursuant to the terms and conditions of an Amendment No. 1 to Note Purchase and Guaranty Agreement, dated as of December 16, 2022 ( the Existing Note Purchase Agreement, as so amended, the "Amended Note Agreement"), by and among the Company and the Operating Partnership, together with certain subsidiary guarantors as initial guarantor parties thereto and The Prudential Insurance Company of America and the various other purchasers named therein.

 Neither the term of the Existing Note Agreement, the interest rate, nor the principal amounts, were amended. The purpose of the amendment is to conform certain covenants and defined terms contained in the Amended Note Agreement with the Company's recently amended unsecured credit facility with the lenders party thereto, Bank of Montreal, as administrative agent, Truist Bank, as syndication agent, and BMO Capital Markets Corp., Truist Bank, Capital One, National Association, and U.S. Bank National Association, as co-lead arrangers and joint book runners.

 The principal of the Series A Notes began to amortize on March 22, 2023 with annual principal payments of approximately $ 7.1 million. The principal of the Series B Notes will begin to amortize on March 22, 2025 with annual principal payments of $ 10.0 million. The Notes will pay interest quarterly on the 22nd day of March, June, September and December in each year until maturity.

 The Operating Partnership may prepay at any time all, or from time to time part of, the Notes, in an amount not less than $ 1,000,000 in the case of a partial prepayment, at 100 % of the principal amount so prepaid, plus a make-whole amount. The make-whole amount is equal to the excess, if any, of the discounted value of the remaining scheduled payments with respect to the Notes being prepaid over the aggregate principal amount of such Notes (as described in the Note Agreement). In addition, in connection with a Change of Control (as defined in the Note Purchase Agreement), the Operating Partnership is required to offer to prepay the Notes at 100 % of the principal amount plus accrued and unpaid interest thereon.

 The Note Agreement contains representations, warranties, covenants, terms and conditions customary for transactions of this type and substantially similar to the Operating Partnership's existing senior revolving credit facility, including limitations on liens, incurrence of investments, acquisitions, loans and advances and restrictions on dividends and certain other restricted payments. In addition, the Note Agreement contains certain financial covenants substantially similar to the Operating Partnership's existing senior revolving credit facility, including the following:

 •

 maximum total indebtedness to total asset value ratio of 0.60 to 1.00;

 •

 maximum secured debt to total asset value ratio of 0.40 to 1.00;

 •

 minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges ratio of 1.50 to 1.00;

 •

 maximum secured recourse debt to total asset value ratio of 0.15 to 1.00;

 •

 maintenance of a minimum tangible net worth (adjusted for accumulated depreciation and amortization) of 75 % of the Company's total net worth as of December 31, 2021 plus 75 % of the net proceeds from additional equity offerings (as defined therein); and

 •

 minimum adjusted property NOI to implied unencumbered debt service ratio of 1.50 to 1.00.

 In addition, the Note Agreement contains a financial covenant requiring that maximum unsecured indebtedness to unencumbered asset pool of 0.60 to 1.00. That covenant is substantially similar to the borrowing base concept contained in the Operating Partnership's existing senior revolving credit facility.

 The Note Agreement also contains default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-performance of covenants, cross-defaults with other indebtedness and guarantor defaults. The occurrence of an event of default under the Note Agreement could result in the Purchasers accelerating the payment of all obligations under the Notes. The financial and restrictive covenants and default provisions in the Note Agreement are substantially similar to those contained in the Operating Partnership's existing credit facility.

 F-

 Net proceeds from the Private Placement were used to refinance existing indebtedness. The Notes have not been and will not be registered under the Securities Act of 1933, as amended (the "Securities Act"), and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act. The Notes were sold in reliance on the exemption from registration provided by Section 4 (a)( 2) of the Securities Act.

 On September 16, 2022, we, through our Operating Partnership, entered into an unsecured credit facility (the "2022 Facility") with the lenders party thereto, Bank of Montreal, as administrative agent (the "Administrative Agent"), Truist Bank, as syndication agent, and BMO Capital Markets Corp., Truist Bank, Capital One, National Association, and U.S. Bank National Association, as co-lead arrangers and joint book runners. The 2022 Facility amended and restated the Company's previous unsecured revolving credit facility, dated January 31, 2019 ( the "2019 Facility").

 The 2022 Facility is comprised of the following two tranches:

 •

 $ 250.0 million unsecured revolving credit facility with a maturity date of September 16, 2026 ( the "2022 Revolver"); and

 •

 $ 265.0 million unsecured term loan with a maturity date of January 31, 2028 ( "Term Loan")

 Borrowings under the 2022 Facility accrue interest (at the Operating Partnership's option) at a Base Rate or an Adjusted Term Secured Overnight Financing Rate ("SOFR") plus an applicable margin based upon our then existing leverage. As of December 31, 2023, the interest rate on the 2022 Revolver was 7.05 %. Based on our current leverage ratio, the revolver has initial interest rate of SOFR plus 1.60 % and a 10 basis point credit spread adjustment. In addition, we entered into interest rate swaps to fix the interest rates on the Term Loan. The Term Loan with the swaps has the following interest rates:

 •

 2.16 % plus 1.55 % through October 28, 2022

 •

 2.80 % plus 1.55 % from October 29, 2022 through January 31, 2024

 •

 3.42 % plus 1.55 % from February 1, 2024 through January 31, 2028

 The 2022 Facility also has a pricing provision where the applicable margin can be adjusted by an aggregate 0.02 % per annum based on the Company's performance on certain sustainability performance targets. Base Rate means, for any day, the higher of: (a) the Administrative Agent's prime commercial rate, (b) the sum of (i) the rate per annum equal to the weighted average of the rates on overnight federal funds transactions with members of the Federal Reserve System, as published by the Federal Reserve Bank of New York for such day, plus (ii) 0.50 %, or (c) the sum of (i) Adjusted Term SOFR for a one -month tenor in effect on such day plus (ii) 1.10 %. Adjusted Term SOFR means, for any such day, the sum of (i) the SOFR-based term rate for the day two ( 2) business days prior and (ii) 0.10 %.

 The 2022 Facility includes an accordion feature that will allow the Operating Partnership to increase the borrowing capacity by $ 200.0 million, upon the satisfaction of certain conditions. As of December 31, 2023, subject to any potential future paydowns or increases in the borrowing base, we have $ 104.0 million remaining availability under the 2022 Revolver. As of December 31, 2023, $ 411.0 million was drawn on the 2022 Facility and our unused borrowing capacity was $ 104.0 million, assuming that we use the proceeds of the 2022 Facility to acquire properties, or to repay debt on properties, that are eligible to be included in the unsecured borrowing base. The Company used $ 379.5 million of proceeds from the 2022 Facility to repay amounts outstanding under the 2019 Facility.

 F-

 The Company, each direct and indirect material subsidiary of the Operating Partnership and any other subsidiary of the Operating Partnership that is a guarantor under any unsecured ratable debt will serve as a guarantor for funds borrowed by the Operating Partnership under the 2022 Facility. The 2022 Facility contains customary terms and conditions, including, without limitation, customary representations and warranties and affirmative and negative covenants including, without limitation, information reporting requirements, limitations on investments, acquisitions, loans and advances, mergers, consolidations and sales, incurrence of liens, dividends and restricted payments. In addition, the 2022 Facility contains certain financial covenants including the following:

 •

 maximum total indebtedness to total asset value ratio of 0.60 to 1.00;

 •

 maximum secured debt to total asset value ratio of 0.40 to 1.00;

 •

 minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges ratio of 1.50 to 1.00;

 •

 maximum other recourse debt to total asset value ratio of 0.15 to 1.00; and

 •

 maintenance of a minimum tangible net worth (adjusted for accumulated depreciation and amortization) of $ 449 million plus 75 % of the net proceeds from additional equity offerings (as defined therein).

 The 2022 Facility also contains customary events of default with customary notice and cure, including, without limitation, nonpayment, breach of covenant, misrepresentation of representations and warranties in a material respect, cross-default to other major indebtedness, change of control, bankruptcy and loss of REIT tax status. If an event of default occurs and is continuing under the 2022 Facility, the lenders may, among other things, terminate their commitments under the 2022 Facility and require the immediate payment of all amounts owed thereunder.

 As of December 31, 2023, our $ 136.7 million in secured debt was collateralized by five properties with a carrying value of $ 212.3 million. Our loans contain restrictions that would require the payment of prepayment penalties for the acceleration of outstanding debt and are secured by deeds of trust on certain of our properties and by assignment of the rents and leases associated with those properties. As of December 31, 2023, we were in compliance with all loan covenants.

 On March 31, 2023, we, through our Operating Partnership, entered into an interest rate swap of $ 50 million ("Revolver Swap") with Bank of Montreal that fixed the unhedged SOFR portion of the variable rate debt at 3.71 %. Pursuant to the terms of the agreement governing the interest rate swap, Bank of Montreal assigned $ 10.0 million of the swap to U.S. Bank, $ 10.0 million of the swap to Capital One, $ 12.5 million of the swap to SunTrust Bank, and $ 2.5 million of the swap to Associated Bank. The swap began on March 31, 2023 and will mature on September 16, 2026. We designated the interest rate swap as a cash flow hedge with the effective portion of the changes in fair value recorded in comprehensive income and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. The Company does not expect any amount of the existing gains or losses to be reclassified into earnings within the next 12 months.

 On September 16, 2022, we, through our Operating Partnership, entered an interest rate swap with Bank of Montreal that fixed the unhedged SOFR portion of Term Loan under the 2022 Facility at 3.32 %. The notional amount of the swap begins at $ 100 million on October 29, 2022, and increases to $ 265 million on February 1, 2024, maturing on January 31, 2028. Pursuant to the terms of the agreement governing the interest rate swap, Bank of Montreal assigned beginning and ending notionals of $ 20.7 million and $ 54.8 million of the swap, respectively, to U.S. Bank, National Association, beginning and ending notionals of $ 25.4 million and $ 67.2 million of the swap, respectively, to Truist Bank, beginning and ending notionals of $ 20.7 million and $ 54.8 million of the swap, respectively, to Capital One, National Association, and beginning and ending notionals of $ 5.9 million and $ 15.7 million of the swap, respectively, to Associated Bank. See Note 8 (Debt) for additional information regarding the 2022 Facility. We designated the interest rate swap as a cash flow hedge with the effective portion of the changes in fair value recorded in comprehensive income and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. The Company does not expect any amount of the existing gains or losses to be reclassified into earnings within the next 12 months.

 On January 31, 2019, we, through our Operating Partnership, entered into an interest rate swap of $ 165 million with Bank of Montreal that fixed the LIBOR portion of our $ 165 million term loan under the 2019 Facility at 2.43 %. Pursuant to the terms of the agreement governing the interest rate swap, Bank of Montreal assigned $ 32.6 million of the swap to U.S. Bank, National Association, $ 29.4 million of the swap to Regions Bank, $ 40.0 million of the swap to SunTrust Bank, and $ 15.0 million of the swap to Associated Bank. Effective September 7, 2022, Regions Bank novated $ 29.4 million of the swap to Bank of Montreal. See Note 8 (Debt) for additional information regarding the 2019 Facility. The swap began on February 8, 2021 and will mature on January 31, 2024. Effective September 16, 2022, our contracts indexed to LIBOR were converted to SOFR. We have designated the interest rate swap as a cash flow hedge with the effective portion of the changes in fair value to be recorded in comprehensive income and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. The ineffective portion of the change in fair value, if any, will be recognized directly in earnings. The Company does not expect any amount of the existing gains or losses to be reclassified into earnings within the next 12 months.

 On November 19, 2015, we, through our Operating Partnership, entered into a $ 100 million interest rate swap with Bank of Montreal that fixed the LIBOR portion of our $ 100 million term loan under the 2018 Facility at 1.73 %. In the fourth quarter of 2015, pursuant to the terms of the agreement governing the interest rate swap, Bank of Montreal assigned $ 35.0 million of the swap to U.S. Bank, National Association, and $ 15.0 million of the swap to SunTrust Bank. See Note 8 (Debt) for additional information regarding the 2018 Facility. The swap began on November 30, 2015 and matured on October 28, 2022. We designated the interest rate swap as a cash flow hedge with the effective portion of the changes in fair value recorded in comprehensive income.

 10. EARNINGS PER SHARE

 Basic earnings per share for our common shareholders is calculated by dividing income from continuing operations excluding amounts attributable to unvested restricted shares and the net income attributable to non-controlling interests by our weighted-average common shares outstanding during the period. Diluted earnings per share is computed by dividing the net income attributable to common shareholders excluding amounts attributable to unvested restricted shares and the net income attributable to non-controlling interests by the weighted-average number of common shares including any dilutive unvested restricted shares.

 Certain of our performance-based restricted common shares are considered participating securities, which require the use of the two -class method for the computation of basic and diluted earnings per share. During the years ended December 31, 2023, 2022 and 2021, 693,803, 737,983, and 772,383 OP units, respectively, were excluded from the calculation of diluted earnings per share because their effect would be anti-dilutive.

 For the years ended December 31, 2023, 2022 and 2021, distributions of $ 0, $ 0 and $ 0, respectively, were made to the holders of certain restricted common shares, none of which were charged against earnings. See Note 14 for information related to restricted common shares under the 2008 Plan.

 11. FEDERAL INCOME TAXES

 Federal income taxes are not provided because we intend to and believe we qualify as a REIT under the provisions of the Code and because we have distributed and intend to continue to distribute all of our taxable income to our shareholders. Our shareholders include their proportionate taxable income in their individual tax returns. As a REIT, we must distribute at least 90% of our real estate investment trust taxable income to our shareholders and meet certain income sources and investment restriction requirements. In addition, REITs are subject to a number of organizational and operational requirements. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate tax rates.

 Taxable income differs from net income for financial reporting purposes principally due to differences in the timing of recognition of interest, real estate taxes, depreciation and rental revenue.

 For federal income tax purposes, the cash distributions to shareholders are characterized as follows for the years ended December 31:

Mastandrea, the former Chairman and Chief Executive Officer of Whitestone REIT, also served as the Chairman and Chief Executive Officer of Pillarstone REIT and beneficially owns approximately 66.7 % of the outstanding equity in Pillarstone REIT (when calculated in accordance with Rule 13d - 3 (d)( 1) under the Exchange Act of 1934, as amended (the "Exchange Act")). He resigned as a member of the Board of Whitestone REIT on April 18, 2022. Prior to his employment termination, February 9, 2022, Mr. John J. Dee, the Company's former Chief Operating Officer and Corporate Secretary, also served as the Senior Vice President and Chief Financial Officer of Pillarstone REIT and beneficially owns approximately 20.0 % of the outstanding equity in Pillarstone REIT (when calculated in accordance with Rule 13d - 3 (d)( 1) under the Exchange Act). In addition, Mr. Paul T. Lambert, a Trustee of the Company, until expiration of his term on May 12, 2023, also served as a Trustee of Pillarstone REIT.

 The Contribution is pursuant to the Company's strategy of recycling capital by disposing of Non-Core Properties that do not fit the Company's Community Centered Property strategy and the terms of the Contribution Agreement, the OP Unit Purchase Agreement, the Tax Protection Agreement and the Contribution were determined through arm's-length negotiations. The Contribution was unanimously approved and recommended by a special committee of independent Trustees of the Company. See Note 4 for additional disclosure on the Contribution.

 Pillarstone OP. In accordance with ASU 2014 - 09 ("Topic 606") and ASC 610, " Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets," the Company recognizes its investment in Pillarstone OP under the equity method.

 During the ordinary course of business, we had transactions with Pillarstone OP that include, but are not limited to, rental income, interest expense, general and administrative costs, commissions, management and asset management fees, and property expenses. The management agreement was terminated on August 18, 2022.

 13. EQUITY

 Under our declaration of trust, as amended, we have authority to issue up to 400 million common shares of beneficial interest, $ 0.001 par value per share, and up to 50 million preferred shares of beneficial interest, $ 0.001 par value per share.

 Equity Offerings

 On May 20, 2022, our universal shelf registration statement on Form S- 3 was declared effective by the SEC, which registers the issuance and sale by us of up to $ 500 million in securities from time to time, including common shares, preferred shares, debt securities, depositary shares and subscription rights.

 On September 9, 2022, we entered into eleven equity distribution agreements for an at-the-market equity distribution program (the "2022 equity distribution agreements") providing for the issuance and sale of up to an aggregate of $ 100 million of the Company's common shares pursuant to our Registration Statement on Form S- 3 (File No. 333 - 264881). Actual sales will depend on a variety of factors determined by us from time to time, including (among others) market conditions, the trading price of our common shares, capital needs and our determinations of the appropriate sources of funding for us, and were made in transactions that will be deemed to be "at-the-market" offerings as defined in Rule 415 under the Securities Act. We have no obligation to sell any of our common shares and can at any time suspend offers under the 2022 equity distribution agreements or terminate the 2022 equity distribution agreements.

 We have in the past, and expect to in the future, enter into at-the-market equity distribution programs providing for the issuance and sale of common shares. Actual sales will depend on a variety of factors determined by us from time to time, including (among others) market conditions, the trading price of our common shares, capital needs and our determinations of the appropriate sources of funding for us, and were made in transactions that will be deemed to be "at-the-market" offerings as defined in Rule 415 under the Securities Act of 1933, as amended (the "Securities Act"). For the years ended December 31, 2023 and 2022, we did not sell common shares under the equity distribution agreements.

 Operating Partnership Units

 Substantially all of our business is conducted through the Operating Partnership. We are the sole general partner of the Operating Partnership. As of December 31, 2023, we owned a 98.6 % interest in the Operating Partnership.

 Limited partners in the Operating Partnership holding OP units have the right to redeem their OP units for cash or, at our option, common shares at a ratio of one OP unit for one common share. Distributions to OP unit holders are paid at the same rate per unit as distributions per share to Whitestone common shares. As of December 31, 2023 and 2022, there were 50,182,938 and 49,996,356 OP units outstanding, respectively. We owned 49,489,991 and 49,301,876 OP units as of December 31, 2023 and 2022, respectively. The balance of the OP units is owned by third parties, including certain trustees. Our weighted-average share ownership in the Operating Partnership was approximately 98.6 %, 98.6 % and 98.3 % for the years ended December 31, 2023, 2022 and 2021, respectively. For the years ended December 31, 2023 and 2022, 1,533 and 76,010 OP units, respectively, were redeemed for an equal number of common shares.

 14. INCENTIVE SHARE PLAN

 The Company's 2008 Long-Term Equity Incentive Ownership Plan (as amended, the "2008 Plan") expired in July 2018. At the Company's annual meeting of shareholders on May 11, 2017, our shareholders voted to approve the 2018 Long-Term Equity Incentive Ownership Plan (the "2018 Plan"). The 2018 Plan provides for the issuance of up to 3,433,831 common shares and OP units pursuant to awards under the 2018 Plan. The 2018 Plan became effective on July 30, 2018, which is the day after the 2008 Plan expired.

 The Compensation Committee administered the 2008 Plan and administers the 2018 Plan except, in each case, with respect to awards to non-employee trustees, for which the 2008 Plan was and the 2018 Plan is administered by the board of trustees. The Compensation Committee is authorized to grant share options, including both incentive share options and non-qualified share options, as well as share appreciation rights, either with or without a related option. The Compensation Committee is also authorized to grant restricted common shares, restricted common share units, performance awards and other share-based awards. On September 6, 2017, the Compensation Committee approved the grant of an aggregate of 965,000 performance-based restricted common share units under the 2008 Plan which only vest immediately prior to the consummation of a Change in Control (as defined in the 2008 Plan) that occurs on or before September 30, 2024 ( the "CIC Units") to certain of our employees. Continued employment is required through the vesting date. If a Change in Control does not occur on or before September 30, 2024, the CIC Units shall be immediately forfeited. The Company considers a Change in Control on or before September 30, 2024 to be improbable, and no expense has been recognized for the CIC Units. If a Change in Control occurs, any outstanding CIC Units would be expensed immediately on the date of the Change in Control using the grant date fair value. The grant date fair value for each CIC Unit of $ 13.05 was determined based on the Company's closing share price on the grant date. On January 1, 2020, the remaining unvested 247,978 TSR units that were granted on September 6, 2017 vested at 200 % achievement into 495,956 common shares.

 Total compensation recognized in earnings for share-based payments was $ 3.7 million, $ 1.5 million, and $ 5.9 million for the years ended December 31, 2023, 2022, and 2021, respectively.

 As of December 31, 2023, there were 455,000 CIC Units outstanding that we do not expect to vest before their period of restriction lapses in 9 months because the Company considers a Change in Control unlikely on or before September 30, 2024. As of December 31, 2023, there was approximately $ 2.6 million in unrecognized compensation cost related to outstanding non-vested TSR Units, which are expected to vest over a period of 24 months and approximately $ 2.7 million in unrecognized compensation cost related to outstanding non-vested time-based shares, which are expected to be recognized over a period of approximately 30 months beginning on January 1, 2024.

 We expect to record approximately $ 5.3 million in share-based compensation subsequent to the year ended December 31, 2023. The unrecognized share-based compensation cost is expected to vest over a weighted average period of 23 months. The dilutive impact of the performance-based shares will be included in the denominator of the earnings per share calculation beginning in the period that the performance conditions are expected to be met. The dilutive impact of the TSR Units is based on the Company's TSR Peer Group Ranking as of the reporting date and weighted according to the number of days outstanding in the period. As of December 31, 2023, the TSR Peer Group Ranking called for 200 % and 150 % attainment of the TSR Units granted in 2022 and 2023, respectively. The dilutive impact of the CIC Units is based on the probability of a Change in Control. Because the Company considers a Change in Control on or before September 30, 2024 to be improbable, no CIC Units are included in the Company's dilutive shares.

 16. COMMITMENTS AND CONTINGENCIES

 Guarantor for Pillarstone OP's loan

 The Company has a limited guarantee on Pillarstone OP's loan for its Uptown Tower property located in Dallas, Texas, with an aggregate principal amount of $ 14.4 million as of September 30, 2023. The guarantee is a so-called "bad boy" carve-out guarantee, which is generally only applicable if and when the borrower engages in acts such as fraud, prohibited transfers, breaches of material representations, environmental matters, and bankruptcy. The debt matured on October 4, 2023, and is currently in default, as Pillarstone OP failed to refinance the loan. The loan is also secured by the Uptown Tower property.

 On October 24, 2023, the Lender provided notice of a planned foreclosure sale on December 5, 2023. The Lender also claimed that an additional sum of $ 4.6 million was due which included default interest of approximately $ 6.3 million and net credits from escrowed funds and other charges of approximately $ 1.7 million. The default interest charges are in dispute, and we believe that the value of Uptown Tower exceeds the total amount claimed by the Lender.

 On December 1, 2023, the Company reached an agreement with the Lender that would avoid foreclosure and secure the release of the lien and discharge of the guarantee, and the Company negotiated and satisfied a payoff as of December 4, 2023, in the amount of $ 13,632,764 (the "DPO Amount"). The DPO Amount included a compromise settlement of approximately $ 1,688,000 for the disputed default interest and other fees. The Company's share of it was recorded in the 4th quarter of fiscal year 2023 in the financial statement line equity (deficit) in earnings of real estate partnership. Per the agreement, this payment would satisfy the Loan. The Company wired the DPO Amount to Lender on December 4, 2023, with accompanying releases as required by Lender, fully satisfying the agreement.

 On December 1, 2023, Pillarstone OP authorized and filed the Chapter 11 bankruptcy of its special purpose entity borrower that owns Uptown Tower (Whitestone Uptown Tower LLC) in Case No. 23 - 32832 -mvl- 11, in the United States Bankruptcy Court for the Northern District of Texas.

 On January 25, 2024, the Company exercised its notice of redemption for substantially all of its investment in Pillarstone OP.

 On February 9, 2024, the Lender filed suit in New York County, New York against the guarantor Whitestone OP and the Company for alleged amounts due under the guarantee. The compromise settlement is our best estimate of the amount due.

 On March 4, 2024, Pillarstone REIT authorized and filed the Chapter 11 bankruptcy of itself, Pillarstone OP, and the remainder of its special purpose entities in the United States Bankruptcy Court for the Northern District of Texas.

 The Company paid the DPO amount will be entitled to assert a subrogation claim against Pillarstone OP. As of the date of this filing, Whitestone has not received consideration for its redemption of its equity investment in Pillarstone OP as required by the partnership agreement. The Company intends to pursue collection of amounts due from Pillarstone OP including the DPO amount and believe the amount will be in excess of the current carrying value of our equity investment in Pillarstone OP. The Company does not believe a probable loss will be incurred, nor does it anticipate a material adverse effect on its financial position, results of operations, cash flows or liquidity. Therefore, the Company has not recorded a charge as a result of Pillarstone REIT bankruptcy.

 Former COO Litigation

 On May 9, 2023, the Company's former COO, John Dee, filed suit against the Company in the District Court of Harris County, Texas. Claimant purports to assert claims for breach of his change-in-control agreement arising from the Company's termination of its former CEO James Mastandrea for cause, and is seeking monetary relief in excess of $ 1,000,000 in damages and equitable relief. The Company denies the claims, has substantial legal and factual defenses against the claims, and intends to vigorously defend against the claims. The Company does not believe a probable loss will be incurred, nor does it anticipate a material adverse effect on its financial position, results of operations, cash flows or liquidity. Therefore, the Company has not recorded a charge as a result of this action.

 Litigation between the Company and Pillarstone REIT

 On September 16, 2022, Pillarstone Capital REIT and Pillarstone Capital REIT Operating Partnership, L.P. filed suit against the Company and certain of its subsidiaries (Whitestone TRS, Inc. and Whitestone REIT Operating Partnership, L.P.) along with certain of its executives (Peter Tropoli, Christine Mastandrea, and David Holeman) in the District Court of Harris County, Texas, alleging claims relating to the limited partnership agreement between Pillarstone Capital REIT and Whitestone REIT Operating Partnership, as well as the termination of Management Agreements between Pillarstone Capital REIT Operating Partnership, L.P. and Whitestone TRS, Inc. On November 25, 2022, the claims against Peter Tropoli, Christine Mastandrea and David Holeman were dismissed. The claimants seek monetary relief in excess of $ 1,000,000 in damages and equitable relief. However, the Company denies the claims, has substantial legal and factual defenses against the claims, and intends to vigorously defend against the claims. The Company does not believe a probable loss will be incurred, nor does it anticipate a material adverse effect on its financial position, results of operations, cash flows or liquidity. Therefore, the Company has not recorded a charge as a result of this action.

 Former CEO Litigation

 On February 23, 2022, the Company's former CEO, James Mastandrea, filed suit against the Company and certain of its trustees (Nandita Berry, Jeff Jones, Jack Mahaffey, and David Taylor) and officers (David Holeman, Christine Mastandrea, Peter Tropoli) in the District Court of Harris County, Texas, alleging claims relating to the termination of his employment. Claimant purports to assert claims for breach of his employment contract, negligence, tortious interference with contract, civil conspiracy, and declaratory judgment. On September 12, 2022, the claim for breach of fiduciary duty was dismissed and a claim for negligence was added (as to the trustee defendants). The claimant seeks a maximum of $ 25 million in damages and equitable relief.

 On December 6, 2023, the 215th District Court of Harris County granted summary judgement and dismissed all claims against the Company related to the termination of Mr. Mastandrea. The court also dismissed all claims against certain of the Company's trustees and officers. The dismissal is subject to appeal. The Company's counter-claims against Mr. Mastandrea for breach of fiduciary duty, theft, and conversion of company property remain in place. A trial to adjudicate the Company's counter-claims against Mr. Mastandrea is scheduled to begin on August 12, 2024.

 Pillarstone Rights Plan

 On December 26, 2021, the Board of Trustees of Pillarstone REIT adopted a new shareholder rights agreement (the "Pillarstone Rights Agreement"). Because Pillarstone REIT sought to use the Pillarstone Rights Agreement to prevent Whitestone OP from exercising its contractual Redemption Right, on July 12, 2022, Whitestone OP filed suit against Pillarstone REIT in the Court of Chancery of the State of Delaware challenging the Pillarstone Rights Agreement.

 On September 8, 2022, Whitestone OP's Motion to Preserve the Status Quo was granted by the Court, limiting Pillarstone OP from engaging in any acts outside the ordinary course of business and otherwise imposing restrictions on Pillarstone OP to ensure that Whitestone's right of redemption is not impaired while the underlying dispute is being considered by the Court.

 On January 25, 2024, the Delaware Court of Chancery: held that Pillarstone breached the implied covenant of good faith and fair dealing when it adopted the Pillarstone Rights Agreement that thwarted Whitestone OP from exercising the unfettered contractual redemption right it obtained in connection with its investment in the partnership; and the Court held that the Rights Plan was unenforceable as to the limited partner and allowed Whitestone OP to exercise its redemption right; allowed Pillarstone to determine the current value of the Partnership's assets; and, as necessary, later enter a monetary judgment against Pillarstone for the difference between the amount Whitestone would have received in or around December 2021 and the current value.

 On January 25, 2024, the Company exercised its notice of redemption for substantially all of its investment in Pillarstone OP.

 On March 4, 2024, Pillarstone REIT authorized and filed the Chapter 11 bankruptcy of itself, Pillarstone OP, and the remainder of its special purpose entities in the United States Bankruptcy Court for the Northern District of Texas.

 As of the date of this filing, Whitestone has not received consideration for its redemption of its equity investment in Pillarstone OP as required by the partnership agreement. We intend to pursue collection of amounts due from Pillarstone OP through all means, including further litigation if necessary and while we do not know the ultimate amount to be collected, we believe the amount will be in excess of the current carrying value of our equity investment in Pillarstone OP.

 We are subject to various legal proceedings and claims that arise in the ordinary course of business. These matters are generally covered by insurance. While the resolution of these matters cannot be predicted with certainty, management believes the final outcome of such matters will not have a material adverse effect on our financial position, results of operations, cash flows or liquidity.

 19. SUBSEQUENT EVENTS

 On January 25, 2024, the Delaware Court of Chancery held that Pillarstone breached the implied covenant of good faith and fair dealing when it adopted shareholder rights plan (the "Rights Plan") that effectively thwarted Whitestone OP from exercising the unfettered contractual redemption right it obtained in connection with its investment in the partnership and the Court held that the Rights Plan was unenforceable as to the limited partner and allowed Whitestone OP to exercise its redemption right. On January 25, 2024, the Company exercised its notice of redemption for substantially all of its investment in Pillarstone OP.

 On February 20, 2024, we acquired Garden Oaks Shopping Center for $ 27.2 million in cash and net prorations. Garden Oaks Shopping Center, a 106,858 square foot property, was 95.8 % leased at the time of purchase and is located in Houston, Texas.
