 Form 10-K Summary

 ITEM 1 - Business

 Chicago Rivet & Machine Co. (the "Company") was incorporated under the laws of the State of Illinois in December 1927, as successor to the business of Chicago Rivet & Specialty Co. The Company operates in the United States in two segments as determined by its products. The fastener segment, which comprises the Company's wholly-owned subsidiary, H&L Tool Company Inc., and the Company's fastener operations, which consists of the manufacture and sale of rivets, cold-formed fasteners and parts, and screw machine products. The assembly equipment segment consists primarily of the manufacture of automatic rivet setting machines and parts and tools for such machines.

 The principal market for the Company's products is the North American automotive industry. Sales are solicited by employees and by independent sales representatives.

 The segments in which the Company operates are characterized by active and substantial competition. No single company dominates the industry. The Company's competitors include both larger and smaller manufacturers, and segments or divisions of large, diversified companies with substantial financial resources. Principal competitive factors in the market for the Company's products are price, quality and service.

 The Company serves a variety of customers. Revenues are primarily derived from sales to customers involved, directly or indirectly, in the manufacture of automobiles and automotive components. The level of business activity for the Company is closely related to the overall level of industrial activity in the United States. During 2023 sales to three customers were each at least 10% of the Company's consolidated revenues. Sales to TI Group Automotive Systems, LLC accounted for approximately 16% and 15% of the Company's consolidated revenues in 2023 and 2022, respectively. Sales to Cooper-Standard Holdings Inc. accounted for approximately 14% of the Company's consolidated revenues in both 2023 and 2022. Sales to Martinrea International Inc. accounted for approximately 11% of the Company's consolidated revenues in 2023.

 The Company's business has historically been stronger during the first half of the year due to the seasonality of automotive manufacturing.

 The Company purchases raw material from a number of sources, primarily within the United States. There are numerous sources of raw material, and the Company does not have to rely on a single source for any of its requirements.

 Patents, trademarks, licenses, franchises and concessions are not of significant importance to the business of the Company.

 The Company does not engage in significant research activities, but rather in ongoing product improvement and development. The amounts spent on product development activities in the last two years were not material.

 At December 31, 2023, the Company employed 207 people.

 The Company has no foreign operations. Sales to foreign customers represent approximately 18% of the Company's total sales in 2023.

 ITEM 1A - Risk Factors

 Our business is subject to a number of risks and uncertainties. If any of the events contemplated by the following risks actually occur, then our business, financial condition or results of operations could be materially adversely affected. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business, financial condition and results of operations.

 Our business over the last few years has been significantly affected by domestic and global economic and market conditions, including rising costs, supply chain disruptions and labor pressures.

 During 2022 and 2023 our business has experienced a period of significant material, labor and shipping price volatility (generally resulting from an increase in the price of commodities, energy costs, freight costs, labor costs and other input costs), as well as supply chain disruptions, in addition to an environment of rising interest rates. While some of these input cost increases moderated in fiscal 2023, other exposures will likely continue in fiscal 2024 and perhaps further into the future. This environment of significant price volatility has resulted in, and may continue to result in, increased costs that may not be, or may only be partially, offset by increasing sales prices and expense reduction. During this same period, we also experienced constrained labor availability which has resulted in inflationary wage pressures, both internally and at key vendors. Although we have developed and implemented strategies to mitigate the impact of supply chain disruptions along with the impact of higher input and other costs, these strategies, together with commercial negotiations with our customers and suppliers, typically offset only a portion (less than 100%) of the adverse impact. Additionally, our operating model typically requires long lead times between the design and development of products, the launch of production and the delivery of the final product. This lead time requires us to secure vendor supply well in advance to minimize launch and production inefficiencies. During such lead times, price commitments are subject to change and could lead to an inability to fully recover all such price changes.

 Labor shortages could prevent us from meeting customer demand.

 We and some of our third-party suppliers and service providers have experienced and may continue to experience a shortage of qualified labor at our and their facilities. A prolonged shortage of qualified labor could decrease our third-party vendors' ability to meet our demands and efficiently operate their facilities. Prolonged labor shortage could also lead to decreased productivity and increased labor costs from higher overtime, the need to hire temporary help to meet demand and higher wages rates in order to attract and retain employees. Any of these developments could materially increase our operating costs and have a material adverse effect on our business, results of operations and financial condition.

 We are dependent on the automotive industry.

 Demand for our products is directly related to conditions in the global automotive industry, which is highly cyclical and is affected by a variety of factors, including regulatory requirements, international trade policies, and consumer spending and preferences. The automotive industry is characterized by fierce competition and has undergone major restructuring in recent years. The impact of evolving technological changes, including a growing emphasis on electric vehicles, as well as any decline in the automotive industry, domestic or foreign, could have a material adverse effect on our business, results of operations and financial condition.

 We face intense competition.

 We compete with a number of other manufacturers and distributors that produce and sell products similar to ours. Price, quality and service are the primary elements of competition. Our competitors include a large number of independent domestic and international suppliers. We are not as large as a number of these companies and do not have as many financial or other resources. Faced with intense domestic and international competition and pressure to reduce costs, many customers have expanded their sourcing of components worldwide. As a result, we have experienced competition from suppliers in other parts of the world that benefit from economic advantages, such as lower labor costs, lower health care costs and fewer regulatory burdens. There can be no assurance that we will be able to compete successfully with existing or new competitors. Increased competition could have a material adverse effect on our business, results of operations and financial condition.

 We rely on sales to major customers.

 Our sales to three customers constituted approximately 41% of our consolidated revenues in 2023. Sales to TI Group Automotive Systems, LLC, Cooper-Standard Holdings Inc, and Martinrea International Inc. accounted for approximately 16%, 14%, and 11% of the Company's consolidated revenues in 2023, respectively. The loss of any significant portion of our sales to these customers could have a material adverse effect on our business, results of operations and financial condition.

 We are subject to risks related to export sales.

 Our export sales have increased in recent years, and we are working to continue to expand our business relationships with customers outside of the United States. Export sales are subject to various risks, including risks related to changes in local economic, social and political conditions (particularly in emerging markets), changes in tariffs and trade policies and foreign currency exchange rate fluctuations, which could have a material adverse effect on our business, results of operations and financial condition.

 Increases in our raw material costs or difficulties with our suppliers could negatively affect us.

 While we currently maintain alternative sources for raw materials, our business is subject to the risk of price fluctuations and periodic delays in the delivery of certain raw materials. At various times in recent years, we have been adversely impacted by increased costs for steel, our principal raw material, which we have been unable to wholly mitigate, as well as increases in other materials prices, including price increases due to inflation. Any continued fluctuation in the price or availability of our raw materials could have a material adverse impact on our business, results of operations and financial condition.

 We may be adversely affected by supply chain disruptions.

 Many of our customers depend upon intricate just-in-time supply chain systems. A disruption in a supply chain caused by one or more suppliers, and/or an unrelated supplier, due to part shortages, work stoppages, labor shortages, economic hardships or bankruptcy, raw material shortages, transportation disruptions, natural disasters, health emergencies, tariffs, etc. could adversely impact our business, or our customers' business, which could have a material adverse effect on our business, results of operations and financial condition.

 We may be adversely affected by labor relations issues.

 Although none of our employees are unionized, the domestic automakers and many of their suppliers, including many of our customers, have unionized work forces. Work stoppages or slow-downs experienced by automakers or their suppliers could result in slow-downs or closures of assembly plants where our products are included in assembled components. In the event that one or more of our customers or their customers experiences a material labor relations issue, our business, results of operations and financial condition could be materially adversely affected.

 We may incur losses as a result of product liability, warranty or other claims that may be brought against us.

 We face risk of exposure to warranty and product liability claims in the event that our products fail to perform as expected or result, or are alleged to have resulted, in bodily injury, property damage or other losses. In addition, if any of our products are or are alleged to be defective, then we may be required to participate in a product recall. We may also be involved from time to time in legal proceedings and commercial or contractual disputes. Any losses or other liabilities related to these exposures could have a material adverse effect on our business, results of operations and financial condition.

 We could be adversely impacted by environmental laws and regulations.

 Our operations are subject to environmental laws and regulations. Currently, environmental costs and liabilities with respect to our operations, and the cost of compliance with such laws and regulations, are not considered material to our business, but there can be no assurance that we will not be adversely impacted by these costs and liabilities in the future either under present laws and regulations or those that may be adopted or imposed in the future.

 We could be adversely impacted by the loss of the services of key employees.

 The successful operation of our business depends, in part, upon the efforts of our executive officers and other key employees. Our current success depends, and our future success will depend, in part, upon our ability to attract and retain qualified personnel. Loss of the services of any of our key employees, or the inability to attract or retain employees could have a material adverse affect upon our business, financial condition and results of operations.

 Any significant disruption, interruption or failure of our information systems could disrupt the operation of our business, result in increased costs and decreased revenues and expose us to liability.

 Cybersecurity threats are growing in number and sophistication and include, among others, malicious software, attempts to gain unauthorized access to data, and other electronic security breaches that could lead to disruptions in critical systems, unauthorized release of confidential or otherwise protected information and corruption of data. In addition to security threats, we are also subject to other systems failures, including network, software or hardware failures, whether caused by us, third-party service providers, natural disasters, power shortages, terrorist attacks or other events. The unavailability of our information systems, the failure of these systems to perform as anticipated or any significant breach of data security could cause loss of data, disrupt our operations, lead to financial losses from remedial actions, require significant management attention and resources, and negatively impact our reputation among our customers, which could have a negative impact on our business, results of operations and financial condition.

 The price of our common stock is subject to volatility, and our stock is thinly-traded.

 Various factors, such as general economic changes in the financial markets, announcements or significant developments with respect to the automotive industry, actual or anticipated variations in our or our competitors' quarterly or annual financial results, the introduction of new products or technologies by us or our competitors, changes in other conditions or trends in our industry or in the markets of any of our significant customers, changes in governmental regulation, or changes in securities analysts' estimates of our competitors or our industry, could cause the market price of our common stock to fluctuate substantially.

 Our common stock is traded on NYSE American (not registered, trading privileges only). The average daily trading volume for our common stock during 2023 was less than 3,000 shares per day. As a result, shares of our common stock may be difficult to sell, and the price of our common stock may vary significantly based on trading volume.

 We face risks in connection with our internal control over financial reporting, and material weaknesses were identified.

 As more fully disclosed in Item 9A. Controls and Procedures, material weaknesses were identified that existed as of December 31, 2023, regarding deficiencies in internal control over financial reporting related to income taxes and valuation of inventory.

 ITEM 1B - Unresolved Staff Comments

 None.

 ITEM 1C - Cybersecurity
 We have established policies and processes for assessing, identifying, and managing material risk from cybersecurity threats, and have integrated these processes into our overall risk management systems and processes. We routinely assess material risks from cybersecurity threats, including any potential unauthorized occurrence on or conducted through our information systems that may result in adverse effects on the confidentiality, integrity, or availability of our information systems or any information residing therein.
 We conduct periodic risk assessments to identify cybersecurity threats, as well as assessments in the event of a material change in our business practices that may affect information systems that are vulnerable to such cybersecurity threats. These risk assessments include identification of reasonably foreseeable internal and external risks, the likelihood and potential damage that could result from such risks, and the sufficiency of existing policies, procedures, systems, and safeguards in place to manage such risks.
 Following these risk assessments, we re-design, implement, and maintain reasonable safeguards to minimize identified risks; reasonably address any identified gaps in existing safeguards; and regularly monitor the effectiveness of our safeguards. Responsibility for assessing, monitoring and managing our cybersecurity risks rests with third party expert consultants in conjunction with our IT Director, both reporting to our Chief Executive Officer, to manage the risk assessment and mitigation process.
 As part of our overall risk management system, we monitor and test our safeguards and train our employees on these safeguards, in collaboration with our IT Director and management. Personnel at all levels and departments are made aware of our cybersecurity policies through trainings.
 We engage consultants, or other third parties in connection with our risk assessment processes. These service providers assist us with designing and implementing our cybersecurity policies and procedures, as well as monitoring and testing our safeguards. We require each third-party service provider to certify that it has the ability to implement and maintain appropriate security measures, consistent with all applicable laws, to implement and maintain reasonable security measures in connection with their work with us, and to promptly report any suspected breach of its security measures that may affect our company.
 We have not encountered cybersecurity challenges that have materially impaired our operations or financial standing. For additional information regarding risks from cybersecurity threats, please refer to Item 1A, "Risk Factors," in this Annual Report on Form 10-K.

 ITEM 2 - Properties

 The Company's headquarters is located in Naperville, Illinois. The Company conducts its manufacturing and warehousing operations at three additional facilities. The Naperville property was sold during the third quarter of 2022, and was rented for the remainder of 2022 and the entirety of 2023 as the Company continues to lease office space at the location. Each other facility is owned by the Company and considered suitable and adequate for its present use.

 Of the properties described below, the Madison Heights, Michigan facility is used entirely in the fastener segment. The Albia, Iowa facility is used exclusively in the assembly equipment segment. The Tyrone, Pennsylvania and the Naperville, Illinois facilities are utilized in both operating segments.

 ITEM 3 - Legal Proceedings

 The Company is, from time to time involved in litigation, including environmental claims, in the normal course of business. While it is not possible at this time to establish the ultimate amount of liability with respect to contingent liabilities, including those related to legal proceedings, management is of the opinion that the aggregate amount of any such liabilities, for which provision has not been made, will not have a material adverse effect on the Company's business, financial position, liquidity, results of operations or cash flows.

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

 Forward-Looking Statements

 This discussion contains certain "forward-looking statements" which are inherently subject to risks and uncertainties that may cause actual events to differ materially from those discussed herein. Factors which may cause such differences in events include those disclosed above under "Risk Factors" and elsewhere in this Form 10-K. As stated elsewhere in this filing, such factors include, among other things: risk related to conditions in the domestic and international automotive industry, upon which we rely for sales revenue, the intense competition in our markets, the concentration of our sales with major customers, risks related to export sales, the price and availability of raw materials, supply chain disruptions, labor relations issues and rising costs, losses related to product liability, warranty and recall claims, costs relating to compliance with environmental laws and regulations, information systems disruptions and the threat of cyber attacks, and the loss of the services of our key employees. Many of these factors are beyond our ability to control or predict. Readers are cautioned not to place undue reliance on these forward-looking statements. We undertake no obligation to publish revised forward-looking statements to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events unless required under the federal securities laws.

 RESULTS OF OPERATIONS

 Operating results for 2023 continued to be impacted by commodity and overall economic inflationary factors. While automotive demand remained relatively steady overall during 2023, our timing in obtaining economic relief under restrictive automotive contracts, which are common in the market, lagged the pace of volatility and significantly impacted our margins. Abrupt changes in market prices of certain key materials and other production costs resulted in profitability challenges as we worked with our customers to mitigate the impact. In particular, the process of obtaining updated pricing from customers, to reflect the Company's increased operating costs, takes significant time to complete. As a result, in the interim as the Company has sought to update pricing, its margins have been negatively impacted. Additionally, non-automotive volumes declined year over year. While we have seen improvement in the labor market since the beginning of the year and raw material pricing has receded from historic highs, most of our production-related expenses remain elevated year over year. These conditions are expected to persist in the near term and our focus remains on updating pricing and improving efficiency while pursuing opportunities and relationships in the markets we serve. Fourth quarter sales were $6,780,894 compared to $6,857,154 in the fourth quarter of 2022, a decline of $76,260, or 1.1%. While the decline in sales was relatively minor our input costs remained elevated and contributed to reporting a net loss in the fourth quarter of $1,542,899, or $1.60 per share, compared to a net loss of $1,312,648, or $1.36 per share, in the fourth quarter of 2022. For the full year, net sales were $31,507,722 compared to $33,646,033 in 2022, a decline of $2,138,311, or 6.4%. Net loss for the full year was $4,401,584, or $4.56 per share, compared to net income of $2,867,629, or $2.97 per share in 2022. The positive figure for 2022 includes a pre-tax gain on the sale of our Naperville, Illinois property of $4,738,394 that was reported in the third quarter.

 2023 Compared to 2022

 Fastener segment revenues were $5,965,995 in the fourth quarter of 2023 compared to $6,272,480 in the fourth quarter of 2022, a decline of $306,485, or 4.9%. During the quarter, sales to automotive customers decreased fractionally to $4,147,072 from $4,185,600 in the year earlier quarter. Slightly lower volumes were offset by new pricing agreements put in place during the mid to latter half of the quarter. Non-automotive revenues also decreased fractionally to $1,818,923 from $2,086,880 in the year earlier quarter. Fastener segment revenues for the full year 2023 were $28,161,362 compared to $30,291,547 in 2022, a decrease of $2,130,185, or 7.0%. For the full year 2023, sales to automotive customers were $19,297,188 compared to $18,454,238 in 2022, an increase of $842,950, or 4.6%. Sales to non-automotive customers in 2023 were $8,864,174 compared to $11,837,309 in 2022, a decline of $2,973,135, or 25%. The modest increase in automotive sales was primarily a result of new pricing agreements secured in the fourth quarter of 2023 but were more than offset by higher input costs experienced during the entire year. Overall, non-automotive fastener volume declined year over year. As a result, gross margin for the fastener segment was $(1,267,492) in 2023 compared to $3,167,104 in 2022.

 Assembly equipment segment revenues were $814,899 in the fourth quarter of 2023, compared to $584,674 in the fourth quarter of 2022, an increase of $230,225, or 39.3%. For the full year 2023, assembly equipment segment revenues were $3,346,360, compared to $3,354,486 reported in 2022, a decrease of $8,126, or 0.2%. While assembly equipment revenues remained flat year over year gross margins increased to $667,902 or 3.0% from $648,220 in 2022.

 Selling and administrative expenses were $5,237,656 in 2023 compared to $4,992,521 in 2022, an increase of $245,135, or 4.9%. We incurred an increase in outside consulting of $292,625, primarily related to hiring costs to fill certain positions, an increase in employee compensation expense of $250,133 as these positions were filled and increase in rent expense of approximately $64,150, primarily related to the lease agreement entered into upon the sale of the Naperville facility in the third quarter of 2022. These, and other smaller expense increases, were offset by a reduction in director fees and commissions of $275,677 and $203,464, respectively. The remaining net change relates to various smaller items. As a percentage of net sales, selling and administrative expenses were 16.6% in 2023 compared to 14.8% in 2022.

 As previously disclosed in a Current Report on Form 8-K filed on September 30, 2022, we sold our Naperville, Illinois facility in which the Company's headquarters and warehouse space is located for a selling price of $5,350,000 in cash, less customary closing costs. Concurrently with the completion of the sale, the Company entered into a lease agreement with the purchaser pursuant to which the Company leased the office and warehouse portion of the Naperville facility from the purchaser until December 31, 2022 and after extension will lease the office portion until December 31, 2024. The monthly rent payable by the Company under the Lease for 2023 was $8,500. The sale was undertaken in order to take advantage of favorable market conditions and to reduce the occupancy space devoted to the Company's administrative functions.

 Other income was $108,234 in 2023 compared to $91,433 in 2022. Other income is primarily comprised of interest income on our cash equivalents which increased modestly during the year due to higher interest rates.

 The Company's effective income tax rates were 23.2% and 21.5% in 2023 and 2022, respectively.

 DIVIDENDS

 In determining to pay dividends, the Board considers current profitability, the outlook for longer-term profitability, known and potential cash requirements and the overall financial condition of the Company. The Company paid four regular quarterly dividends in 2023 totaling $0.64 per share. On February 19, 2024, the Board of Directors declared a regular quarterly dividend of $0.10 per share, payable March 20, 2024 to shareholders of record on March 5, 2024. This continues the uninterrupted record of consecutive quarterly dividends paid by the Company to its shareholders that extends over 90 years.

 PROPERTY, PLANT AND EQUIPMENT

 Total capital expenditures in 2023 were $1,078,367. Of this total, $1,041,896 related to fastener segment activities, including $696,557 for cold heading and screw machine equipment, $299,502 for equipment to perform secondary operations and inspection of parts and $45,837 for general plant equipment. Assembly equipment segment additions in 2023 were $5,235 for general plant equipment. Additional investments of $31,236 were made in 2023 for facilities improvements and IT equipment that benefit both the assembly equipment segment and the fastener segment.

 Capital expenditures in 2022 were $969,943. Fastener segment additions accounted for $868,654 of the total, including $92,880 for cold heading and screw machine equipment, $208,028 for equipment to perform secondary operations and inspection of parts and $215,540 for general plant equipment. The remaining $352,206 of fastener segment additions related to building improvements. Assembly equipment segment additions in 2022 were $3,207 for IT equipment. Investments for the benefit of both operating segments, primarily for building improvements, totaled $98,082 during 2022.

 Depreciation expense was $1,275,078 in 2023 and $1,279,870 in 2022.

 LIQUIDITY AND CAPITAL RESOURCES

 Working capital at December 31, 2023 was $13,976,864, a decrease of $6,096,225 from the beginning of the year. A decline in net accounts receivable during the year of $699,255 and a decrease in inventory of $1,793,577 had a negative impact on working capital. The Company's investing activities in 2023 included the proceeds from the sale of property and equipment of $50,422 and the net maturities from short-term investments of $919,880 less capital expenditures of $1,078,367. The only financing activity during 2023 was the payment of $618,325 in dividends on our common stock. These changes and other cash flow activity resulted in a balance of cash, cash equivalents and certificates of deposit of $3,158,195 at the end of 2023 compared to $6,736,101 as of the beginning of the year.

 Management believes that current cash, cash equivalents and operating cash flow will be sufficient to provide adequate working capital for the next twelve months.

 Off-Balance Sheet Arrangements

 The Company has not entered into, and has no current plans to enter into, any off-balance sheet financing arrangements.

 CRITICAL ACCOUNTING POLICIES AND ESTIMATES

 The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the amounts of revenue and expenses during the reporting period. We base our estimates and assumptions on historical experience, current trends and on various other assumptions that are believed to be reasonable under the circumstances. We evaluate our estimates and judgments required by our policies on an ongoing basis and update them as appropriate based on changing conditions. A summary of significant accounting policies can be found in Note 1 of the financial statements.

 Critical accounting estimates are those that require application of management's most difficult, subjective or complex judgments, often as a result of matters that are inherently uncertain and may change in subsequent periods. We have reviewed our accounting estimates, and none were deemed to be considered critical for the accounting periods presented. While we apply our judgment based on assumptions believed to be reasonable under the circumstances, actual results could vary from these assumptions. Additionally, future facts and circumstances could change and impact our estimates and assumptions.

 NEW ACCOUNTING STANDARDS

 The Company's financial statements and financial condition were not, and are not expected to be, materially impacted by new, or proposed, accounting standards. A summary of recent accounting pronouncements can be found in Note 1 of the financial statements.

 OUTLOOK FOR 2024

 Operating results for 2023 were negatively impacted by a number of factors, which the Company's new management team has been working diligently to address. We are committed to addressing these factors and returning to profitability. Operating costs have continued to increase significantly, particularly raw material, tooling, labor, and outside processing costs. Increases that were historically transient have become persistent. As a result, we have engaged in a thorough review of existing pricing and customer contracts and management remains actively engaged with our existing customers to ensure that our pricing reflects current economic conditions. We have had success in many of these interactions in 2023, however, there is still work to be done to ensure that all of our contracts are structured to allow for a return to profitability. We are committed to these efforts to update our pricing, and in connection with these efforts, will continue to evaluate our product lines and customer relationships to seek to identify opportunities to improve our margins and profitability. In addition to the pricing actions described above, we have also initiated reviews within each of our operating segments to ensure that we have a competitive cost structure and pursue actions for further cost and inventory reduction and cash flow improvement. We are also focused on increasing sales to existing and new customers. Assembly equipment revenues and profitability were a bright spot in 2023 and will remain a focus for 2024. Automotive volumes remained steady year over year, however, non-automotive demand decreased significantly. We are committed to identifying and executing on opportunities to expand existing customer relationships and to build new customer relationships going forward. In addition, we note that we increased our capital expenditures in 2023 over the previous year and expect to see the benefits of those investments in the future.

 As previously disclosed in the Current Reports on Forms 8-K that we filed during 2023, a new but experienced management team has been put in place to lead the Company in the next stage of our journey. Gregory D. Rizzo was hired as the Company's Chief Executive Officer in May 2023, and Joel Brown and Bill Stlaske joined the Company as Chief Financial Officer and Vice-President of Sales, respectively, in November of 2023. In addition, Michael J. Bourg, previously President and Chief Operating Officer of the Company, retired in December 2023. We appreciate Mr. Bourg's efforts on behalf of the Company. With an experienced leadership team in place, the Company will focus on the pricing and cost actions discussed above, with a renewed focus on increasing sales with our existing customers as well as identifying new customers, products, and markets for existing products.

 We believe that our sound financial condition, long history of success in a variety of challenging circumstances, as well as our experience, quality, and customer service in a very competitive global marketplace will provide the foundation for improved operating results in the future. We are grateful for the contributions of all our dedicated employees in what was again a very challenging year. We would like to recognize two key contributors who will be retiring in 2024: Michael P. Sweitzer from the Tyrone Pennsylvania facility who has been with the Company for 47 years, including 30 years as the Plant Manager, and Kimberly A. Kirhofer, Corporate Secretary, who has been with the Company for 41 years. These individuals have exemplified loyalty, dedication and commitment to the Company that are hallmarks of our employees and that have been, and remain, critical to the Company's success. We remain grateful to all our customers and shareholders that continue to support and believe in the Company.

 Opinion on the Financial Statements

 We have audited the accompanying consolidated balance sheets of Chicago Rivet & Machine Co. (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of operations, shareholders' equity, and cash flows for the years then ended, and the related notes (collectively referred to as the "financial statements"). In our opinion, the 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 the years then ended, in conformity with accounting principles generally accepted in the United States of America.

 Basis for Opinion

 These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

 Our audits included performing procedures to assess the risks of material misstatement of the 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 financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

 Critical Audit Matters

 Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

 Notes to Consolidated Financial Statements

 1 - Nature of Business and Significant Accounting Policies

 Nature of Business- The Company operates in the fastener industry and is in the business of producing and selling rivets, cold-formed fasteners and parts, screw machine products, automatic rivet setting machines and parts and tools for such machines.

 A summary of the Company's significant accounting policies follows:

 Principles of Consolidation- The consolidated financial statements include the accounts of Chicago Rivet & Machine Co. and its wholly-owned subsidiary, H & L Tool Company, Inc. ("H & L Tool"). All significant intercompany accounts and transactions have been eliminated.

 Revenue Recognition- Revenue is recognized when control of the promised goods or services is transferred to our customers, generally upon shipment of goods or completion of services, in an amount that reflects the consideration we expect to receive in exchange for those goods or services. Sales taxes we may collect concurrent with revenue producing activities are excluded from revenue. Revenue is recognized net of certain sales adjustments to arrive at net sales as reported on the statement of income. These adjustments primarily relate to customer returns and allowances, which vary over time. The Company records a liability and reduction in sales for estimated product returns based upon historical experience. If we determine that our obligation under warranty claims is probable and subject to reasonable determination, an estimate of that liability is recorded as an offset against revenue at that time. As of December 31, 2023 and 2022, reserves for warranty claims were not material.

 Cash received by the Company prior to shipment is recorded as unearned revenue. For certain assembly equipment segment transactions, revenue is recognized based on progress toward completion of the performance obligation using a labor-based measure. Labor incurred and specific material costs are compared to milestone payments per sales contract. Based on our experience, this method most accurately reflects the transfer of goods under such contracts. During 2023, the Company realized $ 342,328 of revenue related to such contracts, and has $ 123,172 for the remaining performance obligation under such contracts which the Company expects to recognize as revenue in the first quarter of 2024. Contract assets of $ 118,301 was recorded relating to these contracts. Shipping and handling fees billed to customers are recognized in net sales, and related costs as cost of sales, when incurred.

 Credit Risk- The Company extends credit on the basis of terms that are customary within our markets to various companies doing business primarily in the automotive industry. The Company has a concentration of credit risk primarily within the automotive industry and in the Midwestern United States. The Company has established an allowance for accounts that may become uncollectible in the future. This estimated allowance is based primarily on management's evaluation of the financial condition of the customer and historical experience. The Company monitors its accounts receivable and charges to expense an amount equal to its estimate of potential credit losses. The Company considers a number of factors in determining its estimates, including the length of time its trade accounts receivable are past due, the Company's previous loss history and the customer's current ability to pay its obligation. The Company also considers current economic conditions, the economic outlook and industry-specific factors in its evaluation. Accounts receivable balances are charged off against the allowance when it is determined that the receivable will not be recovered.

 Cash and Cash Equivalents and Short-Term Investments- The Company considers all highly liquid investments, including U.S. Treasury bills and certificates of deposit, with a maturity of three months or less when purchased to be cash equivalents. Certificates of deposit and treasury bills with an original maturity of greater than three months but less than one year are separately presented as Short-Term Investments at cost which approximates market value. The Company maintains cash on deposit in several financial institutions. At times, the account balances may be in excess of Federal Deposit Insurance Corporation insured limits.

 Fair Value of Financial Instruments- The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, certificates of deposit, treasury bills, accounts receivable and accounts payable approximate fair value based on their short-term nature.

 Inventories- Inventories are stated at the lower of cost or net realizable value, cost being determined by the first-in, first-out method. The value of inventories is reduced for estimated excess and obsolete inventories based on a review of on-hand inventories compared to historical and estimated future sales and usage.

 Property, Plant and Equipment- Properties are stated at cost and are depreciated over their estimated useful lives using the straight-line method for financial reporting purposes. Accelerated methods of depreciation are used for income tax purposes. Direct costs related to developing or obtaining software for internal use are capitalized as property and equipment. Capitalized software costs are amortized over the software's useful life when the software is placed in service. The estimated useful lives by asset category are:

 Asset Category

 Estimated Useful Life

 Land improvements..

 15 to 40 years

 Buildings and improvements

 10 to 40 years

 Machinery and equipment

 5 to 18 years

 Capitalized software costs

 3 to 5 years

 Other equipment

 3 to 10 years

 The Company reviews the carrying value of property, plant and equipment for impairment whenever events and circumstances indicate that the carrying value of an asset may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. In cases where undiscounted expected future cash flows are less than the carrying value, an impairment loss is recognized equal to an amount by which the carrying value exceeds the fair value of assets. There were no triggering events requiring assessment of impairment as of December 31, 2023 and 2022.

 When properties are retired or sold, the related cost and accumulated depreciation are removed from the respective accounts, and any gain or loss on disposition is recognized in current operations. Maintenance, repairs and minor betterments that do not improve the related asset or extend its useful life are charged to operations as incurred.

 Income Taxes— Deferred income taxes are determined under the asset and liability method. Deferred income taxes arise from temporary differences between the income tax basis of assets and liabilities and their reported amounts in the financial statements. Deferred taxes are shown on the balance sheet as a net long-term asset or liability.

 The Company applies a comprehensive model for the financial statement recognition, measurement, classification and disclosure of uncertain tax positions. In the first step of the two-step process, the Company evaluates the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. In the second step, the Company measures the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. As of December 31, 2023 and 2022, the Company determined that there are no uncertain tax positions with a more than 50% likelihood of being realized upon settlement.

 The Company classifies interest and penalties related to unrecognized tax benefits as a component of income tax expense. There were no such expenses in 2023 or 2022.

 The Company's federal income tax returns for the 2020 through 2022 tax years are subject to examination by the Internal Revenue Service ("IRS"). While it may be possible that a reduction could occur with respect to the Company's unrecognized tax benefits as an outcome of an IRS examination, management does not anticipate any adjustments that would result in a material change to the results of operations or financial condition of the Company.

 No statutes have been extended on any of the Company's federal income tax filings. The statute of limitations on the Company's 2020, 2021 and 2022 federal income tax returns will expire on September 15, 2024, 2025 and 2026, respectively.

 The Company's state income tax returns for the 2020 through 2022 tax years are subject to examination by various state authorities with the latest closing period on October 31, 2026. The Company is currently not under examination by any state authority for income tax purposes and no statutes for state income tax filings have been extended.

 Segment Information- The Company reports segment information based on the internal structure and reporting of the Company's operations.

 Net Income Per Share- Net income per share of common stock is based on the weighted average number of shares outstanding of 966,132 in 2023 and 2022.

 Use of Estimates- The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Significant items subject to estimates and assumptions include depreciable lives, deferred taxes and valuation allowances for accounts receivable and inventory obsolescence. Actual results could differ from those estimates.

 Recent Accounting Pronouncements- In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and in November 2018 issued an amendment, ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. ASU 2016-13 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. This may result in the earlier recognition of allowances for losses. ASU 2016-13 and ASU 2018-19 should be applied on either a prospective transition or modified-retrospective approach depending on the subtopic. ASU 2016-13 is effective for annual periods beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. The Company adopted this ASU on January 1, 2023. The impact of the adoption on our consolidated financial statements was not material and primarily resulted in new/enhanced disclosures only.

 In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose its significant segment expense categories and amounts for each reportable segment. The new guidance is effective for fiscal years beginning after December 15, 2023, and interim periods in fiscal years beginning after December 15, 2024. The Company is evaluating the impact of this ASU.

 In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance the transparency and decision usefulness of income tax disclosures providing investors with information to better assess how an entity's operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. The new guidance is effective for annual periods beginning after December 31, 2024. The Company is evaluating the impact that it will have on our consolidated financial statements and disclosures.

 At December 31, 2023, the Company had federal net operating loss carryforwards of approximately $ 6,045,000. The net operating loss carryforwards are not subject to expiration, however are subject to annual utilization limitations for U.S. federal income tax purposes. The Company believes it is more-likely-than-not that its deferred tax assets will be realized, based primarily on its expectation of future taxable income and considering future reversals of existing taxable temporary differences. The Company reviews the need for a valuation allowance on a quarterly basis for each of its tax jurisdictions.

 4 - Profit Sharing Plan- The Company has a noncontributory profit sharing plan covering substantially all employees. Total expenses relating to the profit sharing plan were zero in 2023 and $ 170,000 in 2022.

 The Company does not allocate certain selling and administrative expenses for internal reporting, thus, no allocation was made for these expenses for segment disclosure purposes. Segment assets reported internally are limited to accounts receivable, inventory and long-lived assets. Certain long-lived assets of one plant location are allocated between the two segments based on estimated plant utilization, as this plant serves both fastener and assembly equipment activities. Other assets are not allocated to segments internally and to do so would be impracticable.

 Sales to one customer in the fastener segment accounted for 16 % of consolidated revenues during 2023 and 15 % in 2022. The accounts receivable balance for this customer accounted for 15 % and 19 % of consolidated accounts receivable as of December 31, 2023 and 2022, respectively. Sales to a second customer in the fastener segment accounted for 14 % of consolidated revenues during 2023 and 2022. The accounts receivable balance for this customer accounted for 14 % and 16 % of consolidated accounts receivable as of December 31, 2023 and 2022, respectively. Sales to a third customer were 11 % of consolidated revenue in 2023. The accounts receivable balance for this customer accounted for 20 % of consolidated accounts receivable as of December 31, 2023.

 7 - Gain on Sale of Property - On August 12, 2022, the Company entered into a Purchase and Sale Agreement (the "PSA") with Frontenac Properties LLC (the "Purchaser") pursuant to which the Company agreed, subject to the terms and conditions of the PSA, to sell its facility in Naperville, Illinois, in which the Company's headquarters and warehouse space are located, to the Purchaser. On September 27, 2022, the Company's sale of the facility to the Purchaser was completed for a selling price of $5,350,000 in cash, less customary closing costs. The net gain on the transaction was $4,738,394. A portion of the net proceeds was invested in U.S. Treasury bills and is included in cash and cash equivalents as of December 31, 2022.

 Concurrently with the completion of the sale of the Naperville facility, the Company and the Purchaser entered into a lease agreement pursuant to which the Company leased the office and warehouse portion of the Naperville facility from the Purchaser until December 31, 2022 and the office portion until June 30, 2023. The monthly rent payable by the Company under the lease was $12,500 for the period from the closing until December 31, 2022 and was $ 8,500 for the period from January 1, 2023 to June 30, 2023. For the period from July 1, 2023 through December 31, 2023 the lease was extended on a month to month basis at $ 8,500 per month. The Company adopted the practical expedient for short-term leases under ASC 842 which allows for leases of 12 months or less to be expensed on a straight-line basis over the lease term without reporting on the balance sheet.

 8 - Commitments and Contingencies- The Company recorded rent expense aggregating approximately $ 128,000 and $ 91,000 in 2023 and 2022, respectively. Total future minimum rentals at December 31, 2023 were $ 112,800.

 The Company is, from time to time involved in litigation, including environmental claims, in the normal course of business. While it is not possible at this time to establish the ultimate amount of liability with respect to contingent liabilities, including those related to legal proceedings, management is of the opinion that the aggregate amount of any such liabilities, for which provision has not been made, will not have a material adverse effect on the Company's financial position.

 9. - Risks and Uncertainties for Health Emergencies. Our global operations expose us to risks associated with pandemics, epidemics, or other public health emergencies. Such events could lead to restrictions and mandates, and there could be global impacts resulting directly or indirectly from such an event including labor shortages, logistical challenges, and supply chain disruptions such as increases in costs for certain goods and services. While much of our customer demand and shipments have recovered from the impact of the COVID-19 pandemic, the extent to which any resurgence in the future would impact our business, including the automotive industry upon which we rely for sales, will depend on a number of evolving factors, all of which are highly uncertain and cannot be predicted, and could last for an extended period of time.

 10 - Subsequent Events- On February 19, 2024, the Board of Directors declared a regular quarterly dividend of $ 0.10 per share, or $ 96,613.20, payable March 20, 2024 to shareholders of record on March 5, 2024.

 On January 1, 2024, the Company entered into a one-year lease agreement for the Naperville facility that extends through December 31, 2024 at the rate of $ 9,400 per month.

 ITEM 9 - Changes in and Disagreements with Accountants on
 Accounting and Financial Disclosure

 None.

 ITEM 9A – Controls and Procedures

 Disclosure Controls and Procedures.

 The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, have evaluated the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the "Exchange Act") as of the end of the period covered by this report. Based on such evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, the Company's disclosure controls and procedures were not effective due to weaknesses in internal control over financial reporting as described below.

 Management's Report on Internal Control Over Financial Reporting.

 The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting, as that term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). The Company's management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2023, based on the 2013 criteria established in Internal Control—Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on this assessment, the Company's management has concluded that the Company's internal control over financial reporting was not effective as of December 31, 2023 as described below.

 Material Weaknesses in Internal Control Over Financial Reporting

 A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis.

 A material weakness in internal control over financial reporting related to income taxes was identified in the Company's internal control over financial reporting as previously reported. Specifically, the Company did not design and maintain effective controls related to the review of the presentation of the tax provision related to unusual items.

 A material weakness in internal control over financial reporting related to inventory valuation was identified in the Company's internal control over financial reporting as of December 31, 2023. Specifically, the Company did not design and maintain effective controls related to the review of the valuation of inventory.

 Remediation Plans for the Material Weaknesses

 The Company's management, under the oversight of the Audit Committee, has designed and implemented changes in processes and controls to remediate the material weakness in internal control over financial reporting related to income taxes. We have engaged external tax advisors to review complex tax matters and assist with provision and classification as necessary.

 The Company's management, under the oversight of the Audit Committee, is in the process of designing and implementing changes in processes and controls to remediate the material weakness in internal control over financial reporting related to inventory valuation. Our enhanced design includes the timely review and update of new standards and subsequent review of variance accounts.

 The material weaknesses will not be considered remediated until management completes its remediation plans and the enhanced controls operate for a sufficient period of time and management has concluded, through testing, that the related controls are effective. The Company will monitor the effectiveness of its remediation plans and will refine its remediation plans as appropriate.

 Notwithstanding the material weaknesses noted above, the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer has concluded that our financial statements included in this Annual Report present fairly, in all material respects, our financial position, results of operations, and cash flows for the periods presented in accordance with accounting principles generally accepted in the United States of America.

 This Annual Report on form 10-K is not required to, and does not, include an attestation report of the Company's registered public accounting firm on the Company's internal control over financial reporting, because the Company is not an accelerated filer or a large accelerated filer as defined in Rule 12b-2 under the Exchange Act.

 Changes in Internal Control Over Financial Reporting.

 Except as described above, there have not been any changes in the Company's internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
