PART I

ITEM 1.BUSINESS

General

CompX International Inc. (NYSE American: CIX), incorporated in Delaware in 1993, is a leading manufacturer of security products used in the postal, recreational transportation, office and institutional furniture, cabinetry, tool storage, healthcare applications and a variety of other industries. We are also a leading manufacturer of wake enhancement systems, stainless steel exhaust systems, gauges, throttle controls and trim tabs and related hardware and accessories for the recreational marine and various other industries. Our products are principally designed for use in medium to high-end product applications where design, quality and durability are valued by our customers.

At December 31, 2024, NL Industries, Inc. (NYSE: NL) owns approximately 87% of our outstanding common stock, Valhi, Inc. (NYSE: VHI) owns approximately 83% of NL’s outstanding common stock and a subsidiary of Contran Corporation owns approximately 91% of Valhi’s outstanding common stock. As discussed in Note 1 to our Consolidated Financial Statements, a majority of Contran’s outstanding voting stock is held directly by Lisa K. Simmons, and by family stockholders (Thomas C. Connelly (the husband of Ms. Simmons’ late sister), a family-owned entity and various family trusts established for the benefit of Ms. Simmons, Mr. Connelly and their children) who are required to vote their shares of Contran voting stock in the same manner as Ms. Simmons. Such voting rights are personal to Ms. Simmons and last through April 22, 2030. The remainder of Contran’s outstanding voting stock is held by another trust (the “Family Trust”), which was established for the benefit of Ms. Simmons and her late sister and their children and for which a third-party financial institution serves as trustee. Consequently, at December 31, 2024, Ms. Simmons and the Family Trust may be deemed to control Contran, and therefore may be deemed to indirectly control the wholly-owned subsidiary of Contran, Valhi, NL and us.

Our corporate offices are located at Three Lincoln Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240. Our telephone number is (972) 448-1400. We maintain a website at www.compxinternational.com.

Unless otherwise indicated, references in this report to “we,” “us,” or “our” refer to CompX International Inc. and its subsidiaries taken as a whole.

Forward-Looking Statements

This Annual Report on Form 10-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. Statements in this Annual Report that are not historical facts are forward-looking in nature and represent management’s beliefs and assumptions based on currently available information. In some cases, you can identify forward-looking statements by the use of words such as “believes,” “intends,” “may,” “should,” “could,” “anticipates,” “expects” or comparable terminology, or by discussions of strategies or trends. Although we believe the expectations reflected in such forward-looking statements are reasonable, we do not know if these expectations will be correct. Such statements by their nature involve substantial risks and uncertainties that could significantly impact expected results. Actual future results could differ materially from those predicted. The factors that could cause actual future results to differ materially from those described herein are the risks and uncertainties discussed in this Annual Report and those described from time to time in our other filings with the U.S. Securities and Exchange Commission (the “SEC”) and include, but are not limited to, the following:

- 2 -

​

Should one or more of these risks materialize (or the consequences of such development worsen), or should the underlying assumptions prove incorrect, actual results could differ materially from those currently forecasted or expected. We disclaim any intention or obligation to update or revise any forward-looking statement whether as a result of changes in information, future events or otherwise.

Industry Overview

We manufacture engineered components utilized in a variety of applications and industries. We manufacture mechanical and electrical cabinet locks and other locking mechanisms used in postal, recreational transportation, office and institutional furniture, cabinetry, tool storage, and healthcare applications. We also manufacture wake enhancement systems, stainless steel exhaust systems, gauges, throttle controls, trim tabs and related hardware and accessories for the recreational marine and other industries. We continuously seek to diversify into new markets and identify new applications and features for our products, which we believe provide a greater potential for higher rates of earnings growth as well as diversification of risk. See also Item 7 – “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Business Segments

We have two operating business segments – Security Products and Marine Components. For additional information regarding our segments, see “Part II – Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 2 to the Consolidated Financial Statements.

- 3 -

Manufacturing, Operations and Products

Security Products. Our Security Products segment manufactures mechanical and electrical cabinet locks and other locking mechanisms used in a variety of applications including mailboxes, ignition systems, file cabinets, desk drawers, tool storage cabinets, high security medical cabinetry, integrated inventory and access control secured narcotics boxes, electronic circuit panels, storage compartments, gas station security, vending and cash containment machines. Our Security Products segment has one manufacturing facility in Mauldin, South Carolina and one in Grayslake, Illinois which is shared with Marine Components. We believe we are a North American market leader in the manufacture and sale of cabinet locks and other locking mechanisms. These products include:

A substantial portion of our Security Products’ sales consist of products with specialized adaptations to an individual customer’s specifications, some of which are listed above. We also have a standardized product line suitable for many customers, which is offered through a North American distribution network to locksmith and smaller original equipment manufacturer (“OEM”) distributors via our STOCK LOCKS^® distribution program.

Marine Components. Our Marine Components segment manufactures and distributes wake enhancement systems, stainless steel exhaust components, gauges, throttle controls, trim tabs and related hardware and accessories primarily for ski/wakeboard boats (towboats) and performance boats. Our Marine Components segment has a facility in Neenah, Wisconsin and a facility in Grayslake, Illinois which is shared with Security Products. Our specialty Marine Component products are high precision components designed to operate within tight tolerances in the highly demanding marine environment. These products include:

For information regarding our three principal manufacturing facilities, see “Item 2 – Properties.”

Raw Materials

Our primary raw materials are:

- 4 -

These raw materials are purchased from several suppliers, are readily available from numerous sources and accounted for approximately 13% of our total cost of sales for 2024. Total material costs, including purchased components, represented approximately 46% of our cost of sales in 2024.

We occasionally enter into short-term commodity-related raw material supply arrangements to mitigate the impact of future price increases in commodity-related raw materials, including zinc, brass, aluminum and stainless steel. These arrangements generally provide for stated unit prices based upon specified purchase volumes, which help us to stabilize our commodity-related raw material costs to a certain extent. At other times we may make spot market buys of larger quantities of raw materials to take advantage of favorable pricing or volume-based discounts. Our raw material prices were generally stable through the first half of 2024, although beginning in the latter half of the third quarter we began to experience moderate increases in certain raw material costs, particularly brass. The zinc market was volatile in 2024, but we were successful in making strategic spot buys to keep our costs consistent with 2023. Prices for aluminum and stainless steel, which are the primary raw materials used for the manufacture of marine components (including marine exhaust headers and pipes, wake enhancement systems, throttles and trim tabs), were relatively stable in 2024 because we took advantage of volume purchase opportunities during the year. In most cases, commodity raw materials we purchase include processing and conversion costs, such as alloying, extrusion and rolling, which remain elevated due to costs of labor, transportation, and energy. Processing and conversion costs are not expected to decrease and may negate the benefit of softening commodity prices on our purchases. Based on current economic conditions, we expect the prices for zinc, brass, aluminum, stainless steel and other manufacturing materials in 2025 to be relatively stable, although governmental actions such as tariffs may impact markets. When purchased on the spot market, each of these raw materials may be subject to sudden and unanticipated price increases. When possible, we seek to mitigate the impact of fluctuations in these raw material costs on our margins through improvements in production efficiencies or other operating cost reductions. In the event we are unable to offset raw material cost increases with other cost reductions, it may be difficult to recover those cost increases through increased product selling prices or raw material surcharges due to the competitive nature of the markets in which we compete. Consequently, overall operating margins can be negatively affected by commodity-related raw material cost pressures. Commodity market prices are cyclical, reflecting overall economic trends, specific developments in consuming industries and speculative investor activities.

​

Patents and Trademarks

We hold a number of patents relating to our component products, certain of which we believe to be important to us and our continuing business activity. Patents generally have a term of 20 years, and our patents have remaining terms ranging from 1 to 16 years at December 31, 2024.

Our major trademarks and brand names in addition to CompX^® include:

​

Sales, Marketing and Distribution

A majority of our component sales are direct to large OEM customers through our factory-based sales and marketing professionals supported by engineers working in concert with field salespeople and independent manufacturer’s

- 5 -

representatives. We select manufacturer’s representatives based on special skills in certain markets or relationships with current or potential customers.

In addition to sales to large OEM customers, a substantial portion of our Security Products sales are made through distributors. We have a significant North American market share of cabinet lock security product sales as a result of the locksmith distribution channel. We support our locksmith distributor sales with a line of standardized products used by the largest segments of the marketplace. These products are packaged and merchandised for easy availability and handling by distributors and end users.

We sell to a diverse customer base with only one customer representing 10% or more of our sales in 2024 (United States Postal Service representing 21%). Our largest ten customers accounted for approximately 47% of our sales in 2024.

Competition

The markets in which we participate are highly competitive. We compete primarily on the basis of product design, including space utilization and aesthetic factors, product quality and durability, price, on-time delivery, service and technical support. We focus our efforts on the middle and high-end segments of the market, where product design, quality, durability and service are valued by the customer. Our Security Products segment competes against a number of domestic and foreign manufacturers. Our Marine Components segment competes with small domestic manufacturers and is minimally affected by foreign competitors.

Environmental, Social and Governance (“ESG”)

We seek to operate our business in line with sound ESG principles that include corporate governance, social responsibility, sustainability and cybersecurity. We believe ESG means conducting operations with high standards of environmental and social responsibility, practicing exemplary ethical standards, focusing on safety as a top priority, respecting human rights and supporting our local communities, and continuously developing our employees. At our facilities, we undertake various environmental sustainability programs, and we promote social responsibility and volunteerism through programs designed to support and give back to the local communities in which we operate. Each of our locations maintains site-specific safety programs and disaster response and business continuity plans. All manufacturing facilities have detailed, site-specific emergency response procedures we believe adequately address regulatory compliance, vulnerability to potential hazards, emergency response and action plans, employee training, alarms and warning systems and crisis communication.

In an effort to align our non-employee directors’ financial interests with those of our stockholders, our board of directors established share ownership guidelines for our non-management directors. In addition, we have adopted an insider trading policy that applies to both employees and non-employee directors.

Regulatory and Environmental Matters

We have a history of incorporating environmental management and compliance in our operations and decision making. We operate three manufacturing facilities and our production processes requiring waste-water discharge are consolidated at our Mauldin, South Carolina facility. This facility has received a ReWa Compliance Excellence Award multiple years for its exemplary performance from Renewable Water Resources, an organization which sets regulatory and water policies for the Mauldin facility’s geographic region. In addition, we operate extensive scrap metal recycling programs to reduce landfill waste.

Our operations are subject to federal, state and local laws and regulations relating to the use, storage, handling, generation, transportation, treatment, emission, discharge, disposal, remediation of and exposure to hazardous and non-hazardous substances, materials and wastes, some of which are becoming stricter over time. Our operations also are subject to federal, state and local laws and regulations relating to worker health and safety. We believe we are in substantial compliance with all such laws and regulations. To date, the costs of maintaining compliance with such laws and regulations have not significantly impacted our results; however, it is possible future laws and regulations may require us to incur significant additional expenditures.

Human Capital Resources

Employees – Our operating results depend in part on our ability to successfully manage our human capital resources, including attracting, identifying, and retaining key talent. We have a well-trained labor force with a substantial number of long-tenured employees. We provide competitive compensation and benefits to our employees. In addition to salaries, these programs can include annual bonuses, a defined contribution plan with employer matching, a profit sharing plan, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, family leave, family care resources, employee assistance programs and tuition assistance.

We recognize that everyone deserves respect and equal treatment. We embrace diversity and collaboration in our workforce and our business initiatives. We are an equal opportunity employer, and we base employment decisions on merit, competence and qualifications, without regard to race, color, national origin, gender, age, religion, disability, sex, sexual orientation or other characteristics protected by applicable law in the jurisdictions in which we operate. We promote a respectful, diverse and inclusive workplace in which all individuals are treated with respect and dignity.

As of December 31, 2024, we employed 510 people, all in the United States. We believe our labor relations are good.

Health and Safety – Protecting the health and safety of our workforce, our customers, our business partners and the natural environment is one of our core values. We are committed to maintaining a strong safety culture where all workers meet or exceed required industry performance standards, and we continuously seek to improve occupational and process safety performance. We conduct our business in ways intended to provide all personnel with a safe and healthy work environment and have established safety and environmental programs and goals to achieve these results. We expect our manufacturing facilities to produce our products safely and in compliance with local regulations, policies, standards and practices intended to protect the environment and our people, and we have established policies designed to promote compliance. We require our employees to comply with such requirements. We provide our workers with the tools and training necessary to make the appropriate decisions to prevent accidents and injuries. Each of our operating facilities develops, maintains and implements safety programs encompassing key aspects of their operations. In addition, management reviews and evaluates safety performance throughout the year. We monitor conditions that could lead to a safety incident and keep track of injuries through reporting systems in accordance with laws in the jurisdictions in which we operate. We track this data to assess the quality of our safety performance, and we use lost time incidents as a key measure of worker safety. We define lost time incidents as work-related accidents where a worker sustains an injury that results in time away from work. We had three lost time incidents in 2022, and one in each of 2023 and 2024.

ITEM 1A.RISK FACTORS

Listed below are certain risk factors associated with us and our businesses. In addition to the potential effect of these risk factors discussed below, any risk factor which could result in reduced earnings, operating losses, or reduced liquidity, could in turn adversely affect our ability to service our liabilities or pay dividends on our common stock or adversely affect the quoted market prices for our securities.

Operational Risk Factors

We operate in mature and highly competitive markets, resulting in pricing pressure and the need to continuously reduce costs.

Many of the markets we serve are highly competitive, with a number of competitors offering similar products. We focus our efforts on the middle and high-end segment of the market where we feel that we can compete due to the importance of product design, quality and durability to the customer. However, our ability to effectively compete is impacted by a number of factors. The occurrence of any of these factors could result in reduced earnings or operating losses.

Our development of innovative features for current products is critical to sustaining and growing our sales.

Historically, our ability to provide value-added custom engineered products that address requirements of technology and space utilization has been a key element of our success. We spend a significant amount of time and effort to refine, improve and adapt our existing products for new customers and applications. Since expenditures for these types of activities are not considered research and development expense under accounting principles generally accepted in the United States of America (“GAAP”), the amount of our research and development expenditures, which is not significant, is not indicative of the overall effort involved in the development of new product features. The introduction of new product features requires the coordination of the design, manufacturing and marketing of the new product features with current and potential customers. The ability to coordinate these activities with current and potential customers may be affected by factors beyond our control. While we will continue to emphasize the introduction of innovative new product features that target customer-specific opportunities, we do not know if any new product features we introduce will achieve the same degree of success that we have achieved with our existing products. At times we work with new and existing customers on specific product innovations. Sometimes we have a cost sharing arrangement for development efforts although we may also fully bear the development costs. If a customer were to ultimately reject or abandon custom product innovation efforts, we may not be able to recover our development costs.

- 8 -

Higher costs or limited availability of our raw materials could negatively impact our financial results.

Certain raw materials used in our products are commodities that are subject to significant fluctuations in price in response to world-wide supply and demand as well as speculative investor activity. Zinc and brass are the principal raw materials used in the manufacture of security products. Stainless steel and aluminum are the major raw materials used in the manufacture of marine components. These raw materials are purchased from several suppliers and are generally readily available from numerous sources. We occasionally enter into short-term raw material supply arrangements to mitigate the impact of future increases in commodity-related raw material costs and ensure supply. Materials purchased outside of these arrangements are sometimes subject to unanticipated and sudden price increases.

Certain components used in our products are manufactured by foreign suppliers located in China and elsewhere. Global economic and political conditions, including natural disasters, terrorist acts, transportation disruptions, global conflicts and public health crises such as pandemics, could prevent our vendors from being able to supply these components. Should our vendors not be able to meet their supply obligations or should we be otherwise unable to obtain necessary raw materials or components, we may incur higher supply costs or may be required to reduce production levels. In addition, the imposition of new tariffs or increases in existing tariffs by the U.S. government on imports from China, Mexico or other countries from which we import raw materials and other components could increase our supply costs. Increases in our supply costs may decrease our liquidity or negatively impact our financial condition or results of operations as we may be unable to offset the higher costs with increases in our selling prices or reductions in other operating costs.

Legal, Compliance and Regulatory Risk Factors

We may be subject to litigation, the disposition of which could have a material adverse effect on our results of operations.

The nature of our operations exposes us to possible litigation claims, including disputes with customers and suppliers and matters relating to, among other things, product liability, intellectual property, employment and environmental claims. It is possible that judgments could be rendered against us in these or other types of cases for which we could be uninsured or not covered by indemnity, or which may be beyond the amounts that we currently have reserved or anticipate incurring for such matters. In addition, litigation can be costly, and the costs associated with defending litigation matters could potentially have a material adverse effect on our results of operations.

Failure to protect our intellectual property rights or claims by others that we infringe their intellectual property rights could substantially harm our business.

We rely on patent, trademark and trade secret laws in the United States and similar laws in other countries to establish and maintain our intellectual property rights in our technology and designs. Despite these measures, any of our intellectual property rights could be challenged, invalidated, circumvented or misappropriated. Third parties may independently discover our trade secrets and proprietary information, and in such cases we could not assert any trade secret rights against such parties. Further, we do not know if any of our pending trademark or patent applications will be approved. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our intellectual property rights. In addition, the laws of certain countries do not protect intellectual property rights to the same extent as the laws of the United States. Therefore, in certain jurisdictions, we may be unable to protect our technology and designs adequately against unauthorized third party use, which could adversely affect our competitive position.

Third parties may claim that we or our customers are infringing upon their intellectual property rights. Even if we believe that such claims are without merit, they can be time-consuming and costly to defend and distract our management’s and technical staff’s attention and resources. Claims of intellectual property infringement might also require us to redesign affected technology, enter into costly settlement or license agreements or pay costly damage awards, or face a temporary or permanent injunction prohibiting us from marketing or selling certain of our technology. If we cannot or do not license the infringed technology on reasonable pricing terms or at all, or substitute similar technology from another source, our business could be adversely impacted.

- 9 -

Climate change laws and regulations could negatively impact our financial results or limit our ability to operate our businesses.

All of our production facilities are located in the United States and each requires energy, including electricity and natural gas in order to conduct operations.  The U.S. government has determined that the consumption of energy derived from fossil fuels is a major contributor to climate change and is contemplating regulatory changes in response to the potential impact of climate change, including laws and regulations regarding carbon emission costs, Green House Gas (“GHG”) emissions and renewable energy targets. To date, laws and regulatory actions related to climate change have not had a material adverse effect on our financial results. Until the timing, scope and extent of any new or future regulation becomes known, we cannot predict the effect on our business, results of operations or financial condition. However, if new laws or regulations or regulatory actions related to climate change were to be enacted or implemented, it could negatively impact our future results from operations through increased costs of production, particularly as it relates to our energy requirements. If such increased costs of production were to materialize, we may be unable to pass price increases on to our customers to compensate for increased production costs, which may decrease our liquidity, operating income and results of operations. In addition, any adopted future climate change laws and regulations could negatively impact our ability (or that of our customers and suppliers) to compete with companies situated in areas not subject to such limitations.  

General Risk Factors

Technology failures or cybersecurity breaches could have a material adverse effect on our operations.

We rely on information technology systems to manage, process and analyze data, as well as to facilitate the manufacture and distribution of our products to and from our facilities. We receive, process and ship orders, manage the billing of and collections from our customers, and manage the accounting for and payment to our vendors. Although we have systems and procedures in place to protect our information technology systems, there can be no assurance that such systems and procedures will be sufficiently effective. Therefore, any of our information technology systems may be susceptible to outages, disruptions or destruction from power outages, telecommunications failures, employee error, cybersecurity breaches or attacks and other similar events. This could result in a disruption of our business operations, injury to people, harm to the environment or our assets, and/or the inability to access our information technology systems and could adversely affect our results of operations and financial condition. We have in the past experienced, and we expect to continue to experience, cyber-attacks, including phishing, and other attempts to breach or gain unauthorized access to our systems. To date we have not suffered breaches in our systems, either directly or through a trusted third-party vendor, which have led to material losses. Due to the increase in global cybersecurity incidents it has become increasingly difficult to obtain insurance coverage on reasonable pricing terms to mitigate some risks associated with technology failures or cybersecurity breaches, and we are experiencing such difficulties in obtaining insurance coverage.

Physical impacts of climate change could have a material adverse effect on our costs and operations.

​

Climate change may increase both the frequency and severity of extreme weather conditions and natural disasters such as hurricanes, thunderstorms, tornadoes, drought and snow or ice storms. Extreme weather conditions may increase our costs or cause damage to our facilities, and any damage resulting from extreme weather may not be fully insured. Furthermore, periods of extended inclement weather may inhibit our facility operations and delay or hinder shipments of our products to customers. Any such events could have a material adverse effect on our costs or results of operations.

ITEM 1B.UNRESOLVED STAFF COMMENTS

None.

ITEM 1C.CYBERSECURITY

- 10 -

We have a Cybersecurity Incident Disclosure and Controls Committee (CIDAC) which is central to the response and evaluation of cybersecurity incidents. Our CIDAC is comprised of our director of IT and senior executives including our chief executive officer, chief financial officer and general counsel, and our executive vice president who is also the Contran chief information officer. Security events and data incidents are evaluated, ranked by severity and prioritized for response and remediation. The IT team is responsible for categorizing cybersecurity incidents, and those deemed high-risk or critical are escalated to the CIDAC for review and response coordination.  Incidents are evaluated to determine materiality and for operational, financial and reputational impact. Our CIDAC performs simulations and tabletop exercises at a management level to evaluate our readiness and response to cybersecurity incidents. As needed, we collaborate with external cybersecurity experts and legal advisors to help ensure a robust response strategy.

Our board of directors oversees management’s processes for identifying and mitigating risks, including cybersecurity risks, to help align our risk exposure with our strategic objectives. Senior leadership, including our chief executive officer and chief financial officer, provides regular updates to the board of directors on our cybersecurity posture, emerging threats and our risk mitigation efforts. Our board of directors is apprised of cybersecurity incidents deemed to have significant business impact, even if they are not material to us. The board has delegated some of its primary risk oversight to board committees, including that our audit committee facilitates the board’s process of oversight of our overall risk management approach. Our full board retains oversight of cybersecurity because of its importance to us and visibility with our customers.

​

In the event of an incident, we follow a structured incident response playbook, which outlines clear and defined steps to be followed from incident detection to mitigation, recovery and notification, including notifying functional areas (such as legal), senior leadership and the board, as appropriate. We also conduct post-incident reviews to identify lessons learned and implement continuous improvements.

​

We face a number of cybersecurity risks. To date, such risks have not materially affected us, including our business strategy, results of operations or financial condition. While we have not experienced any major breaches, we actively monitor and mitigate cyber threats, including phishing attempts, malware and targeted attacks. Thus far all such incidents have been minor, isolated and promptly contained. For more information about the cybersecurity risks we face, see the risk factor entitled “Technology failures or cybersecurity breaches could have a material adverse effect on our operations.” in Item 1A- Risk Factors.

ITEM 2.PROPERTIES

Our principal executive offices are located in leased space at 5430 LBJ Freeway, Dallas, Texas 75240. The following table sets forth the location, size and business operating segment for each of our principal operating facilities.

​

SP – Security Products business segment

MC – Marine Components business segment

We believe all of our facilities are well maintained and satisfactory for their intended purposes.

ITEM 3.LEGAL PROCEEDINGS

We are involved, from time to time, in various environmental, contractual, product liability, patent (or intellectual property), employment and other claims and disputes incidental to our business. In addition to the information included below, see Note 11 to our Consolidated Financial Statements.

In 2024, we were served with four lawsuits by public water companies in South Carolina that seek recovery of future costs to remove perfluoroalkyl and polyfluoroalkyl substances (known as “PFAS”) from their water supplies. The lawsuits have been consolidated with other PFAS cases before a single judge in Spartanburg, South Carolina and were subsequently removed to federal court. The defendants in the lawsuits include the manufacturers of PFAS products, as well as companies that allegedly used PFAS-containing products in their manufacturing operations. The four lawsuits naming CompX allege that CompX was one of many companies that used products containing PFAS in its manufacturing operations, and that such operations have collectively impacted drinking water supplies used by the water companies. The plaintiffs do not allege that CompX has failed to comply with, or has violated, any environmental regulation, permit or statute.  The plaintiffs instead assert claims under common law theories of negligence, nuisance, trespass, failure to warn, and unfair trade practices. We intend to deny liability and will defend vigorously against all claims.

ITEM 4.MINE SAFETY DISCLOSURES

Not applicable.

ITEM 6.RESERVED

​

Business Overview

We are a leading manufacturer of engineered components utilized in a variety of applications and industries. Through our Security Products segment we manufacture mechanical and electrical cabinet locks and other locking mechanisms used in postal, recreational transportation, office and institutional furniture, cabinetry, tool storage, healthcare applications and a variety of other industries. We also manufacture wake enhancement systems, stainless steel exhaust systems, gauges, throttle controls, trim tabs and related hardware and accessories for the recreational marine and other industries through our Marine Components segment.

Operating Income Overview

We reported operating income of $17.0 million in 2024 and $25.4 million in each of 2023 and 2022. The decrease in operating income in 2024 compared to 2023 is due to lower sales and gross margin at both Security Products and Marine Components. Operating income in 2023 was comparable to 2022 as lower Marine Components sales were offset by higher Security Products sales and higher gross margin percentages across both segments. See results of operations discussion below.

Our product offerings consist of a large number of products that have a wide variation in selling price and manufacturing cost, which results in certain practical limitations on our ability to quantify the impact of changes in individual product sales quantities and selling prices on our net sales, cost of sales and gross margin. In addition, small variations in period-to-period net sales, cost of sales and gross margin can result from changes in the relative mix of our products sold.

Results of Operations - 2024 Compared to 2023 and 2023 Compared to 2022

​

Net Sales. Net sales decreased $15.4 million in 2024 compared to 2023 primarily due to lower Marine Components sales to the towboat market and lower Security Products sales to the government security market as a result

- 14 -

of sales related to a pilot project that shipped in the third and fourth quarters of 2023 and for which there were no related sales in 2024. See segment results discussion below.

Net sales decreased $5.3 million in 2023 compared to 2022 due to lower Marine Components sales primarily to the towboat market, partially offset by higher Security Products sales largely in the fourth quarter of 2023. See segment results discussion below.

Cost of Sales and Gross Margin. Cost of sales decreased in 2024 compared to 2023 primarily due to the effects of lower sales at both Security Products and Marine Components partially offset by higher production costs across both business segments. As a result, cost of sales as a percentage of net sales increased over the same period. Gross margin as a percentage of net sales decreased in 2024 compared to 2023 primarily due to the factors affecting cost of sales and decreased coverage of fixed costs due to lower sales. See segment results discussion below.

Cost of sales decreased in 2023 compared to 2022 primarily due to the effects of lower production costs at both Security Products and Marine Components as well as lower Marine Components sales. Gross margin as a percentage of net sales increased over the same period primarily due to the factors affecting cost of sales. See segment results discussion below.

Operating Costs and Expenses. Operating costs and expenses consist primarily of sales and administrative-related personnel costs, sales commissions and advertising expenses directly related to product sales and administrative costs relating to business unit and corporate management activities, as well as gains and losses on sales of property and equipment. Operating costs and expenses increased $.5 million in 2024 compared to 2023 predominantly due to higher employee salary and benefit costs at Security Products. As a percentage of net sales, operating costs and expenses increased in 2024 compared to 2023 primarily due to increased operating costs and expenses and decreased coverage of operating cost and expenses due to lower sales. See segment results discussion below.

Operating costs and expenses increased in 2023 compared to 2022 predominantly due to higher salary and benefit costs at Security Products which increased by $.6 million. As a percentage of net sales, operating costs and expenses increased in 2023 compared to 2022 primarily due to the effect of the increased operating costs and expenses on lower sales. See segment results discussion below.

Operating Income. As a percentage of net sales, operating income decreased in 2024 compared to 2023 and increased in 2023 compared to 2022. Operating income margins were primarily impacted by the factors affecting net sales, cost of sales, gross margin and operating costs discussed above. See segment results discussion below.

General. Our profitability primarily depends on our ability to utilize our production capacity effectively, which is affected by, among other things, the demand for our products and our ability to control our manufacturing costs, primarily comprised of labor costs and materials. The materials used in our products consist of purchased components and raw materials some of which are subject to fluctuations in the commodity markets such as zinc, brass, aluminum and stainless steel. Total material costs represented approximately 46% of our cost of sales in 2024, with commodity-related raw materials representing approximately 13% of our cost of sales. Our raw material prices were generally stable through the first half of 2024, although beginning in the latter half of the third quarter we began to experience moderate increases in certain raw material costs, particularly brass. The zinc market was volatile in 2024, but we were successful in making strategic spot buys to keep our costs consistent with 2023. Prices for aluminum and stainless steel, the primary raw materials used for the manufacture of marine components (including marine exhaust headers and pipes, wake enhancement systems, throttles and trim tabs), were relatively stable in 2024 because we took advantage of volume purchase opportunities during the year. In most cases, commodity raw materials we purchase include processing and conversion costs, such as alloying, extrusion and rolling, which remain elevated due to costs of labor, transportation and energy. Processing and conversion costs are not expected to decrease and may negate the benefit of softening commodity prices on our purchases. Based on current economic conditions, we expect the prices for zinc, brass, aluminum, stainless steel and other manufacturing materials in 2025 to be relatively stable, although governmental actions such as tariffs may impact markets.

- 15 -

We occasionally enter into short-term commodity-related raw material supply arrangements to mitigate the impact of future increases in commodity related raw material costs. See Item 1 - “Business- Raw Materials.”

Interest Income. Interest income increased in 2024 compared to 2023 and increased in 2023 compared to 2022.  The increase for both comparative periods is primarily due to higher interest rates and higher average investment balances, somewhat offset by lower average loan balances on our loan to an affiliate. See Notes 3 and 10 to our Consolidated Financial Statements.

Income tax expense. A tabular reconciliation of our actual tax provision to the U.S. federal statutory income tax rate of 21% is included in Note 8 to the Consolidated Financial Statements. As a member of the group of companies consolidated for U.S. federal income tax purposes with Contran, the parent of our consolidated U.S. federal income tax group, we compute our provision for income taxes on a separate company basis, using the tax elections made by Contran.

Our effective income tax rate was 24% in each of 2022, 2023 and 2024. See Notes 8 and 11 to our Consolidated Financial Statements. We currently expect our effective income tax rate for 2025 to be comparable to our effective income tax rate for 2024.

Segment Results

The key performance indicator for our segments is operating income (see discussion below). For additional information regarding our segments refer to Note 2 to our Consolidated Financial Statements.

​

Security Products. Security Products net sales decreased 5% to $115.2 million in 2024 compared to $121.2 million in 2023 primarily due to lower sales to the government security market as a result of sales related to a pilot project for a government security customer that shipped in the third and fourth quarters of 2023 and for which there were no related sales in 2024. Relative to prior year, sales were $8.3 million lower to the government security market, $2.0 million lower to the transportation market and $.9 million lower to distributors, partially offset by $4.1 million higher sales to the healthcare market and $.7 million higher sales to the tool storage market. Gross margin as a percentage of net sales for 2024 decreased as compared to 2023 primarily due to lower sales, a less favorable customer and product mix, higher employee related costs (primarily increased medical costs), higher materials costs (primarily brass and electronics) in the latter half of the year and decreased coverage of fixed costs due to lower sales. Operating income margin decreased for 2024 compared to 2023 primarily due to the factors impacting gross margin, as well as decreased coverage of operating costs and expenses from lower sales and increased operating costs and expenses, including higher employee salaries and benefit costs of $.5 million, primarily in the first half of the year.

Security Products net sales increased 6% to $121.2 million in 2023 compared to $114.5 million in 2022 primarily due to higher sales related to a pilot project for a government security customer. Relative to prior year, sales were $8.3 million higher to the government security market and $1.5 million higher to distributors, partially offset by $1.7 million lower sales to the office furniture market and $.7 million lower sales to the gas station security market. Gross margin as a percentage of net sales for 2023 increased as compared to 2022 primarily due to lower production costs (including lower material, overtime and shipping costs) and increased coverage of fixed costs on higher sales, primarily in the fourth quarter.

- 16 -

Operating income margin increased for 2023 compared to 2022 primarily due to the factors impacting gross margin, as well as increased coverage of operating costs and expenses from higher sales, partially offset by increased operating costs and expenses, including higher employee salaries and benefit costs of $.6 million.

​

Marine Components. Marine Components net sales decreased 23% in 2024 as compared to 2023 primarily due to $8.7 million lower sales to the towboat market through the first three quarters of 2024, partially offset by higher sales in the fourth quarter of 2024, including $1.1 million higher sales to the towboat market and $1.0 million higher sales to the government market. Relative to the full year of 2023, sales were $7.6 million lower to the towboat market (primarily to original equipment boat manufacturers), $1.4 million lower to the industrial market and $.6 million lower to each the engine builder market and distributors, partially offset by $1.4 million higher sales to the government market. Gross margin as a percentage of sales decreased in 2024 compared to 2023 primarily due to higher cost inventory produced during the fourth quarter of 2023 and sold in the first quarter of 2024 and decreased coverage of fixed costs as a result of lower sales, partially offset by a more favorable customer and product mix, lower employee salaries and benefits of approximately $1.8 million primarily related to headcount reductions and decreased labor costs of $1.2 million due to lower production volumes. Operating income as a percentage of net sales decreased in 2024 compared to 2023 due to the factors impacting gross margin, as well as decreased coverage of operating costs and expenses on lower sales, partially offset by reduced operating costs and expenses, including lower employee related expenses of $.2 million.

Marine Components net sales decreased 23% in 2023 as compared to 2022. Relative to prior year, sales were $12.8 million lower to the towboat market (primarily to original equipment boat manufacturers) and $2.0 million lower to the engine builder market, partially offset by $1.2 million higher industrial sales and $.8 million higher sales to the center console boat market. Gross margin as a percentage of sales increased in 2023 compared to 2022 primarily due to lower raw material costs (primarily stainless steel and aluminum), lower supplies costs driven by lower volume, lower shipping costs and lower labor costs from reduced employee overtime due to lower sales volumes, partially offset by decreased coverage of fixed costs as a result of lower sales. Operating income as a percentage of net sales decreased slightly in 2023 compared to 2022 primarily due to the factors impacting gross margin, as well as decreased coverage of operating costs and expenses from lower sales.

Outlook. As noted above, in the second half of 2023 Security Products had significant sales related to a pilot project for a government security customer. Excluding these sales in 2023, Security Products sales would have increased in 2024 as compared to 2023 due to increased sales across a variety of markets, particularly increased sales of mechanical locks to the government security market. At Marine Components, the decline in sales to the towboat market as a result of the contraction in the recreational marine industry that began in the second quarter of 2023 continued through the third quarter of 2024. Marine Components net sales increased in the fourth quarter of 2024 compared to the fourth quarter of 2023 as a result of stabilizing demand in the towboat market as well as increased sales to the government market. Raw material prices remained relatively stable through the first half of the year; however, beginning in the third quarter of 2024 we experienced price increases in certain commodity raw materials, primarily brass and electronic components at Security Products.

We expect Security Products net sales in 2025 to improve modestly over 2024, and we expect gross margin and operating income percentages in 2025 to be slightly above 2024 due to pricing improvements on the Security Products

- 17 -

product mix. We expect Marine Components net sales to increase in 2025 due to higher expected sales to the government and industrial markets. We believe the recreational marine market has stabilized, and we expect Marine Components sales to the towboat market in 2025 will be comparable to 2024. Overall we expect Marine Components to have improved gross margins and operating income percentages in 2025 compared to 2024 due to higher expected sales volumes. During 2024 we were aggressive in aligning our production capabilities and inventories to demand levels. In 2025, we will continue to monitor current and anticipated near-term customer demand levels to ensure our production capabilities and inventories are aligned accordingly.

Our expectations for our operations and the markets we serve are based on a number of factors outside our control. Currently, our supply chains are stable and transportation and logistical delays are minimal. We have in the past experienced global and domestic supply chain challenges, and any future impacts on our operations will depend on, among other things, any future disruption in our operations or our suppliers’ operations, the effect of tariffs and the impact of economic conditions and geopolitical events on demand for our products or our customers’ and suppliers’ operations, all of which remain uncertain and cannot be predicted.

Critical Accounting Policies and Estimates

Our significant accounting policies are more fully described in Note 1 to our Consolidated Financial Statements. Our Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America, or GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. On an ongoing basis we evaluate our estimates, including those related to the recoverability of long-lived assets, the realization of deferred income tax assets, income tax and other contingencies. We base our estimates on historical experience and on various other assumptions which we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the reported amounts of assets, liabilities, revenues and expenses. Actual results may differ significantly from previously-estimated amounts under different assumptions or conditions.

We believe the most critical accounting policies and estimates involving significant judgment primarily relate to the considerations in the impairment assessments for goodwill and certain long-lived assets. We have discussed the development, selection and disclosure of our critical accounting estimates with the audit committee of our board of directors.

When performing a qualitative assessment, considerable management judgment is necessary to evaluate the qualitative impact of events and circumstances on the fair value of a reporting unit. Events and circumstances considered in our impairment evaluations, such as historical profits and stability of the markets served, are consistent with factors utilized with our internal projections and operating plan. However, future events and circumstances could result in materially different findings which could result in the recognition of a material goodwill impairment.

- 18 -

Evaluations of possible impairment utilizing the quantitative impairment test require us to estimate, among other factors: forecasts of future operating results, revenue growth, operating margin, tax rates, capital expenditures, depreciation, working capital, weighted average cost of capital, long-term growth rates, risk premiums, terminal values, and fair values of our reporting units and assets. The goodwill impairment test is subject to uncertainties arising from such events as changes in competitive conditions, the current general economic environment, material changes in growth rate assumptions that could positively or negatively impact anticipated future operating conditions and cash flows, changes in the discount rate, and the impact of strategic decisions. If any of these factors were to materially change, such change may require revaluation of our goodwill. Changes in estimates or the application of alternative assumptions could produce significantly different results.

In 2024, we used the qualitative assessment for our annual impairment test and determined it was not necessary to perform the quantitative goodwill impairment test, as we concluded it is more-likely-than-not the fair value of the Security Products reporting unit exceeded its carrying amount. See Notes 1 and 6 to our Consolidated Financial Statements.

Significant judgment is required in estimating such cash flows. Adverse changes in such estimates of future net cash flows or estimates of fair value could result in an inability to recover the carrying value of the long-lived asset, thereby possibly requiring an impairment charge to be recognized in the future. We do not assess our property and equipment for impairment unless certain impairment indicators are present. We did not evaluate any long-lived assets for impairment during 2024 because no such impairment indicators were present.

Liquidity and Capital Resources

Summary

Our primary source of liquidity on an on-going basis is our cash flow from operating activities, which is generally used to (i) fund capital expenditures, (ii) repay short-term or long-term indebtedness incurred primarily for capital expenditures, business combinations or buying back shares of our outstanding stock and (iii) provide for the payment of dividends (if declared). From time-to-time, we may incur indebtedness to fund capital expenditures, business combinations or other investment activities. In addition, from time-to-time, we may also sell assets outside the ordinary course of business, the proceeds of which are generally used to repay indebtedness (including indebtedness which may have been collateralized by the assets sold) or to fund capital expenditures or business combinations.

Consolidated cash flows

Operating activities. Trends in cash flows from operating activities, excluding changes in assets and liabilities, for the last three years have generally been similar to the trends in our earnings. Depreciation and amortization decreased in 2024 compared to 2023 primarily due to reductions in capital spending in 2023 and 2024 as a result of generally reduced demand levels. Depreciation and amortization in 2023 was comparable to 2022. See Note 1 to our Consolidated Financial Statements.

Changes in assets and liabilities result primarily from the timing of production, sales and purchases. Such changes in assets and liabilities generally tend to even out over time. However, year-to-year relative changes in assets and liabilities can significantly affect the comparability of cash flows from operating activities. Cash provided by operating activities was $22.9 million in 2024 compared to $25.8 million in 2023. The $2.9 million decrease in cash provided by operating activities was primarily the net result of:

- 19 -

Cash provided by operating activities was $25.8 million in 2023 compared to $16.9 million in 2022. The $8.9 million increase in cash provided by operating activities was primarily the result of:

Relative changes in working capital can have a significant effect on cash flows from operating activities. As shown below, the total average days sales outstanding decreased from December 31, 2023 to December 31, 2024 and is primarily impacted by the timing of sales and collections in the last month of the year. For comparative purposes, we have provided 2022 numbers below.

​

As shown below, our average number of days in inventory at  December 31, 2024 was comparable to December 31, 2023 as the increase at Security Products was offset by the decline at Marine Components. Security Products days in inventory at December 31, 2024 increased from December 31, 2023 due to the fulfillment and shipping of a significant order during the fourth quarter of 2023. The average number of days in inventory for Marine Components declined from December 31, 2023 to December 31, 2024 due to elevated inventory balances at December 31, 2023 as a result of prior orders of certain raw materials with longer lead times delivered in the fourth quarter of 2023. For comparative purposes, we have provided 2022 numbers below.

Investing activities. Capital expenditures have primarily emphasized improving our manufacturing facilities and investing in manufacturing equipment, utilizing new technologies and increased automation of the manufacturing process, to provide for increased productivity and efficiency in order to meet expected customer demand and properly maintain our facilities and technology infrastructure. Capital expenditures were $3.7 million in 2022, $1.1 million in 2023 and $1.4 million in 2024. Our 2022 capital expenditures were higher as we accelerated the timeline for certain projects designed to increase capacity and improve our capabilities in response to strong customer demand. Beginning in the latter half of 2022 and continuing through 2024, we limited investments primarily to those expenditures required to meet our existing customer demand and to properly maintain our facilities and technology infrastructure. See Note 2 to our Consolidated Financial Statements.

We expect our capital expenditures for 2025 will be approximately $3.2 million primarily to meet our expected customer demand and those required to properly maintain our facilities and technology infrastructure. Capital spending for 2025 is expected to be funded through cash on hand and cash generated from operations.

- 20 -

We have entered into an unsecured revolving demand promissory note with Valhi under which, as amended, we have agreed to loan Valhi up to $25 million. Our loan to Valhi, as amended, bears interest at prime rate plus 1.00%, payable quarterly, with all principal due on demand, but in any event no earlier than December 31, 2026. Loans made to Valhi at any time under the agreement are at our discretion. Under the promissory note, Valhi repaid a net $5.5 million in 2022 ($24.3 million of gross borrowings and $29.8 million of gross repayments), repaid a net $2.6 million in 2023 ($27.9 million of gross borrowings and $30.5 million of gross repayments) and repaid a net $1.3 million in 2024 ($25.0 million of gross borrowings and $26.3 million of gross repayments). See Note 10 to our Consolidated Financial Statements.

During 2022, we had gross purchases of U.S. treasury marketable securities aggregating $33.0 million. During 2023, we had gross purchases of U.S. treasury marketable securities aggregating $36.3 million and received gross proceeds totaling $36.0 million related to U.S. treasury bill maturities. During 2024, we received gross proceeds totaling $36.0 million related to U.S. treasury bill maturities. See Note 3 to our Consolidated Financial Statements.

Financing activities. Regular quarterly dividends paid totaled $12.4 million and $12.3 million ($1.00 per share, or $.25 per share per quarter) in 2022 and 2023, respectively, and $14.8 million ($1.20 per share, or $.30 per share per quarter) in 2024. In addition, our board of directors declared special dividends on our Class A common stock which totaled $21.5 million ($1.75 per share) paid in August 2022 and $24.6 million ($2.00 per share) paid in August 2024. On March 5, 2025 our board of directors declared a first quarter 2025 dividend of $.30 per share, to be paid on March 25, 2025 to CompX stockholders of record as of March 17, 2025. The declaration and payment of future dividends and the amount thereof, if any, is discretionary and is dependent upon our results of operations, financial condition, cash requirements for our businesses, contractual requirements and restrictions and other factors deemed relevant by our board of directors. The amount and timing of past dividends is not necessarily indicative of the amount or timing of any future dividends which we might pay.

During 2022, we acquired 78,900 shares of our Class A common stock (8,900 shares from affiliates and 70,000 shares in a single market transaction) for an aggregate purchase price of $1.7 million. See Note 9 to our Consolidated Financial Statements.

Future Cash Requirements

We believe cash generated from operations together with cash on hand will be sufficient to meet our liquidity needs for working capital, capital expenditures, debt service and dividends (if declared) for the next twelve months and our long term obligations for the next five years. To the extent that actual operating results or other developments differ materially from our expectations, our liquidity could be adversely affected.

All of our $60.8 million aggregate cash and cash equivalents at December 31, 2024 were held in the U.S.

We periodically evaluate our liquidity requirements, alternative uses of capital, capital needs and available resources in view of, among other things, our capital expenditure requirements, dividend policy and estimated future operating cash flows. As a result of this process, we have in the past and may in the future seek to raise additional capital, refinance or restructure indebtedness, issue additional securities, repurchase shares of our common stock, modify our dividend policy or take a combination of such steps to manage our liquidity and capital resources. In the normal course of business, we may review opportunities for acquisitions, joint ventures or other business combinations in the component products industry. In the event of any such transaction, we may consider using available cash, issuing additional equity securities or increasing our indebtedness or that of our subsidiaries.

Commitments and contingencies

As more fully described in the Notes to the Consolidated Financial Statements, we are a party to various agreements that contractually and unconditionally commit us to pay certain amounts in the future. See Note 11 to our Consolidated Financial Statements. Additionally, we have purchase obligations of $19.8 million ($19.3 million payable in 2025 and $.5 million payable in 2026/2027) which consists of open purchase orders and contractual obligations, primarily commitments to purchase raw materials and for capital projects in process at December 31, 2024. The timing and amount

- 21 -

for purchase obligations are based on the contractual payment amount and the contractual payment date for those commitments.

See Note 11 to our Consolidated Financial Statements for legal proceedings and other commitments.

Recent accounting pronouncements

See Note 13 to our Consolidated Financial Statements.

ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

General. We are exposed to market risk from changes in interest rates and raw materials prices.

Interest rates. We are exposed to market risk from changes in interest rates, primarily related to our note receivable from affiliate and or investment in marketable debt securities. The outstanding principal amount of the note receivable from affiliate of $9.3 million at December 31, 2024 bears interest at prime plus 1.0% (8.5% at December 31, 2024). We received interest income of $1.0 million from the note during 2024.

Raw materials. We will occasionally enter into short term commodity-related raw material supply arrangements to mitigate the impact of future increases in commodity-related raw material costs. We do not have long-term supply agreements for our raw material requirements because either we believe the risk of unavailability of those raw materials is low and we believe the downside risk of price volatility to be too great or because long-term supply agreements for those materials are generally not available. We do not engage in commodity raw material hedging programs.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of CompX International Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of CompX International Inc. and its subsidiaries (the "Company") as of December 29, 2024 and December 31, 2023, and the related consolidated statements of income and comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended December 29, 2024, including the related notes (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 29, 2024 and December 31, 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 29, 2024 in conformity with accounting principles generally accepted in the United States of America.

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 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 of these consolidated financial statements 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. 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 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 matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

​

Revenue Recognition

​

As described in Note 1 to the consolidated financial statements, the Company’s net sales were $145.9 million for the year ended December 29, 2024. The Company’s sales involve single performance obligations to ship products pursuant to customer purchase orders. The Company records revenue when performance obligations are satisfied by transferring control of products to its customers, which generally occurs at point of shipment or upon delivery. Revenue is recorded in an amount that reflects the net consideration the Company expects to receive in exchange for the products.

​

The principal consideration for our determination that performing procedures relating to revenue recognition is a critical audit matter is a high degree of auditor effort in performing procedures related to the Company’s revenue recognition.

​

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process. These procedures also included, among others, testing revenue recognized for a sample of revenue transactions by obtaining and inspecting source documents, such as purchase orders, invoices, proof of shipment, and cash receipts.
