PART I

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 two segments of the fastener industry: fasteners and assembly equipment. The fastener segment 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, automatic assembly equipment and parts and tools for such machines. For further discussion regarding the Company’s operations and segments, see Note 6 of the financial statements which appears on page 9 of the Company’s 2013 Annual Report to Shareholders. The 2013 Annual Report is filed as an exhibit to this report.

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. Information concerning backlog of orders is not considered material to the understanding of the Company’s business due to relatively short production cycles. The level of business activity for the Company is closely related to the overall level of industrial activity in the United States. During 2013, sales to two customers exceeded 10% of the Company’s consolidated revenues. Sales to TI Group Automotive Systems Corporation accounted for approximately 18% of the Company’s consolidated revenues in both 2013 and 2012. Sales to Fisher & Company accounted for approximately 14% and 15% of the Company’s consolidated revenues in 2013 and 2012, respectively.

The Company’s business has historically been stronger during the first half of the year.

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, 2013, the Company employed 235 people.

The Company has no foreign operations, and sales to foreign customers represent only a minor portion of the Company’s total sales.

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.

We are dependent on the domestic automotive industry.

Demand for our products is directly related to conditions in the domestic 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 domestic automotive industry is characterized by fierce competition, and has undergone major restructuring in recent years in response to overcapacity, narrowing profit margins, significant pension and health care liabilities and excess debt. Conditions in the domestic automotive industry declined significantly during 2008, and worsened further in 2009 as the global recession took hold, resulting in a substantial decline in vehicle sales. Overall, automotive production in the United States declined approximately 50 percent between 2000 and 2009, before rebounding in 2010. Although automotive production and sales have increased in 2010 through 2013, any decline in the domestic automotive industry 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. The competitive environment has also changed dramatically over the past several years as our customers, faced with intense international competition and pressure to reduce costs, have expanded their worldwide sourcing of components. As a result, we have experienced competition from suppliers in other parts of the world that enjoy 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 two major customers.

Our sales to two customers constituted approximately 32% and 33% of our consolidated revenues in 2013 and 2012, respectively. Sales to TI Group Automotive Systems Corporation accounted for approximately 18% of the Company’s consolidated revenues in both 2013 and 2012. Sales to Fisher & Company accounted for approximately 14% and 15% of the Company’s consolidated revenues in 2013 and 2012, 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.

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. In recent years, we have been adversely impacted by increased

4

Table of Contents

costs for steel, our principal raw material, which we have been unable to wholly mitigate, as well as increases in other materials prices. 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 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 are not material, 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.

Successful operations depend, in part, upon the efforts of executive officers and other key employees. 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.

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 the NYSE MKT (not registered, trading privileges only). The average daily trading volume for our common stock during 2013 was less than 4,000 shares per day. As a result, you may have difficulty selling shares of our common stock, and the price of our common stock may vary significantly based on trading volume.

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: conditions in the domestic automotive industry, upon which we rely for sales revenue, the intense competition in our markets, the concentration of our sales to two major customers, the price and availability of raw materials, labor relations issues, losses related to product liability, warranty and recall claims, costs relating to environmental laws and regulations, 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.

RESULTS OF OPERATIONS

Results for 2013 reflect strong growth in sales and net income compared to the year earlier periods. Revenues were $37,117,830 in 2013, an 8.5 percent increase from $34,223,772 reported in 2012. This includes a 14.2 percent increase in

8

Table of Contents

revenues, to $9,202,673, in the fourth quarter of 2013 from $8,056,614 in the fourth quarter of 2012. Both the fastener segment and the assembly equipment segment achieved increases in revenue and higher gross margins during the year, aided by growth in domestic automotive production, which is our primary market, as well as increased sales to certain non-automotive customers. The increase in revenue and improved margins resulted in a 42 percent increase in net income, to $2,479,029, or $2.57 per share, compared with net income of $1,745,741, or $1.81 per share, in 2012. These positive results have allowed us to make significant investments in production equipment and facilities improvements in 2013, while increasing shareholder distributions.

2013 Compared to 2012

The average age of vehicles on U.S. roads reached a new high in 2013, which, coupled with an improving economy, led to increased sales of automobiles and light trucks during the year. Our fastener segment, which relies on the automotive sector for the majority of its revenues, benefited from this environment as well as our ongoing efforts to increase sales in all markets. Fastener segment sales were $33,616,593 in 2013, compared with $30,999,163 in 2012, an increase of 8.4 percent. This marked the fourth consecutive year of sales exceeding the year earlier period. Favorable material pricing in combination with higher sales resulted in an increase in fastener segment gross margins of $1,054,281 during 2013 compared to 2012.

Assembly equipment segment revenues were $3,501,237 in 2013, an increase of $276,628, or 8.6 percent, compared to $3,224,609 recorded in 2012. An increase in the number of machines shipped, as well as a certain high-value order shipped during the fourth quarter of 2013, accounted for most of the increase in the assembly equipment segment sales. The higher sales for the segment combined with overhead costs that were kept at levels consistent with the prior year, resulted in an increase in assembly equipment segment gross margins of $157,372 in 2013.

Selling and administrative expenses were $5,397,861 in 2013, an increase of $211,101, or 4.1 percent, compared to the 2012 total of $5,186,760. The change is primarily due to an increase in profit sharing expense of $114,600, related to improved operating results, and higher commissions of $89,477 related to the increase in sales. As a percentage of net sales, selling and administrative expenses declined from 15.2 percent in 2012 to 14.5 percent in 2013.

Other income was $160,835 in 2013 compared to $118,099 in 2012. The increase was primarily due to gains on the sale of certain equipment formerly used in our fastener segment operations, as a result of the investment in new equipment.

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. In November 2013, the quarterly dividend was increased from $.15 per share to $.18 per share. The Company paid four regular quarterly dividends totaling $.63 per share during 2013. On February 17, 2014, the Board of Directors declared a regular quarterly dividend of $.18 per share, payable March 20, 2014 to shareholders of record on March 5, 2014. This continues the uninterrupted record of consecutive quarterly dividends paid by the Company to its shareholders that extends over 80 years. At that same meeting, the Board also declared an extra dividend of $.40 per share payable March 20, 2014 to shareholders of record on March 5, 2014.

PROPERTY, PLANT AND EQUIPMENT

Capital expenditures during 2013 totaled $3,474,858, of which $3,092,842 was invested in equipment for our fastener operations. Cold heading and screw machine equipment comprised $2,678,440 of the total and $414,402 was expended for equipment used in performing secondary operations on parts, inspection equipment and other general plant equipment. Assembly equipment segment additions totaled $90,010, primarily for building improvements. Additional investments of $292,006 for building improvements and office equipment were made in 2013 that benefit both operating segments.

Total capital expenditures in 2012 were $1,187,746, of which $1,018,734 was invested in equipment for our fastener operations. Inspection equipment accounted for $450,720 of the fastener segment additions while cold heading and screw machine equipment comprised $371,466 of the total. Equipment to perform secondary operations on parts accounted for $46,582, while the remaining additions of $149,966 were for various general plant and office equipment. Assembly equipment segment additions in 2012 were $68,203, for a new turning center. Investments for the benefit of both operating segments, primarily for building improvements, totaled $100,809 during 2012.

Depreciation expense amounted to $1,093,062 in 2013 and $993,951 in 2012.

LIQUIDITY AND CAPITAL RESOURCES

Working capital at December 31, 2013 was $15.5 million, a reduction of $.3 million from the beginning of the year. The most significant factor reducing working capital during the year was the $2.3 million increase in capital expenditures during the year compared to 2012. Partially offsetting that amount was the $.9 million increase in accounts receivable as of year-end as a result of higher fourth quarter sales. The Company’s holdings in cash, cash equivalents and certificates of deposit amounted to $6.7 million at the end of 2013, a decrease of $.8 million. The Company’s investing activities in 2013 consisted primarily of capital expenditures of $3.5 million. The only financing activity during 2013 was the payment of $.6 million in dividends.

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

Off-Balance Sheet Arrangements

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

APPLICATION OF CRITICAL ACCOUNTING POLICIES

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. A summary of critical accounting policies can be found in Note 1 of the financial statements.

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 2014

While automotive sales did not reach the double digit growth levels of the previous three years, 2013 was nonetheless another strong year for the automotive sector, which outperformed the overall economy. Currently, most forecasts call for automotive sales in 2014 to improve to their highest level since 2007, which would again outpace the overall domestic economy. Pent-up demand, low interest rates and an improving housing market are all factors cited to support this view. Our fastener segment should continue to benefit, based on this outlook, as the majority of that segment’s revenue comes from that market sector. Growth in our assembly equipment segment, which has a broader customer base, is more closely tied to overall economic activity and may be more difficult due to the moderate economic growth forecast and the inclusion of a certain large order in 2013 sales.

During the past year, we benefited from favorable material pricing, however, history has shown that raw material prices can be volatile and forecasting such costs is difficult. Many of our customers expect us to keep prices unchanged due to similar expectations from their customers, making it difficult to recover such increases in costs. In early 2014, we incurred a significant increase in health insurance expense which will impact results throughout the year. Additionally, heating and fuel costs are higher than a year earlier due to the harsh winter. While we will continue our efforts to mitigate such increases through rigorous quoting and by working to improve our operational efficiency, based on the size of some of these increases, the potential success of such efforts is uncertain.

Our profitable results since the end of the recent recession have allowed us to make significant investments in our operations, which have provided additional capacity and production capabilities. We believe these investments are necessary to allow us to take advantage of opportunities that may improve revenue and profitability in the future. We will continue to pursue new customer relationships and work to build on existing ones in all the markets we serve by emphasizing value over price and by concentrating our efforts on producing more complex parts for which our expertise, quality and service are important factors in our customers’ purchasing decisions.

There are many factors that contributed to the successful results in 2013 and will need to be present for future success. A key element is the dedicated efforts of our employees, who consistently work to meet the ever-changing challenges that characterize today’s manufacturing environment. We gratefully acknowledge their contributions as well as the loyalty of our customers, who have placed their confidence in us to provide them with quality solutions. We also take this opportunity to thank our shareholders for their support.

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, with the participation of the Company’s Chief Executive Officer and President, Chief Operating Officer and Treasurer (the Company’s principal financial officer), assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).

The attestation report requirement for non-accelerated filers was permanently removed from the Sarbanes-Oxley Act by Section 989C of the Dodd-Frank Act as adopted by the SEC.

Changes in Internal Control Over Financial Reporting.

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, 2013 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders

of Chicago Rivet & Machine Co.

We have audited the accompanying consolidated balance sheets of Chicago Rivet & Machine Co. (an Illinois corporation) and subsidiary (the “Company”) as of December 31, 2013 and 2012, and the related consolidated statements of income, retained earnings, and cash flows for each of the two years in the period ended December 31, 2013. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Chicago Rivet & Machine Co. and subsidiary as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the two years in the period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.
