NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2026

(unaudited)

Note 1 – Organization and basis of presentation:

Organization. We (NYSE American: CIX) were approximately 87% owned by NL Industries, Inc. (NYSE: NL) at March 31, 2026. At March 31, 2026, Valhi, Inc. (NYSE: VHI) owned approximately 83% of NL’s outstanding common stock and a wholly-owned subsidiary of Contran Corporation owned approximately 91% of Valhi’s outstanding common stock. 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 March 31, 2026, 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.

Basis of presentation. Consolidated in this Quarterly Report are the results of CompX International Inc. and its subsidiaries. The unaudited Condensed Consolidated Financial Statements contained in this Quarterly Report have been prepared on the same basis as the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2025 that we filed with the Securities and Exchange Commission (“SEC”) on March 4, 2026 (the “2025 Annual Report”). In our opinion, we have made all necessary adjustments (which include only normal recurring adjustments) in order to state fairly, in all material respects, our consolidated financial position, results of operations and cash flows as of the dates and for the periods presented. We have condensed the Consolidated Balance Sheet at December 31, 2025 contained in this Quarterly Report as compared to our audited Consolidated Financial Statements at that date, and we have omitted certain information and footnote disclosures (including those related to the Consolidated Balance Sheet at December 31, 2025) normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Our results of operations for the interim period ended March 31, 2026 may not be indicative of our operating results for the full year. The Condensed Consolidated Financial Statements contained in this Quarterly Report should be read in conjunction with our 2025 Consolidated Financial Statements contained in our 2025 Annual Report.

Our operations are reported on a 52 or 53-week year. For presentation purposes, annual and quarterly information in the Condensed Consolidated Financial Statements and accompanying notes are presented as ended March 31, 2025, December 31, 2025 and March 31, 2026. The actual dates of our annual and quarterly periods are March 30, 2025, December 28, 2025 and March 29, 2026, respectively. Unless otherwise indicated, references in this report to “we”, “us” or “our” refer to CompX International Inc. and its subsidiaries, taken as a whole.

​

On July 4, 2025, the One Big Beautiful Bill Act was signed into law. It did not have a material impact on our consolidated financial statements.

​

Note 7 – Leases:

In March 2026, we entered into an operating lease for our distribution center located in Southern California. Upon commencement, we recognized an operating lease right-of-use asset and a corresponding operating lease liability, which are included in our Condensed Consolidated Balance Sheet. As of March 31, 2026, the remaining lease term of our operating lease was approximately 7 years and the discount rate associated with such lease was 6.75%.

Note 8 – Commitments and contingencies:

From time to time, we may be involved in various environmental, contractual, product liability, patent (or intellectual property), employment and other claims and disputes incidental to our business. At least quarterly our management discusses and evaluates the status of any pending litigation to which we are a party. The factors considered in such evaluation include, among other things, the nature of such pending cases, the status of such pending cases, the advice of legal counsel and our experience in similar cases (if any). Based on such evaluation, we make a determination as to whether we believe (i) it is probable a loss has been incurred, and if so if the amount of such loss (or a range of loss) is reasonably estimable, or (ii) it is reasonably possible but not probable a loss has been incurred, and if so if the amount of such loss (or a range of loss) is reasonably estimable, or (iii) the probability a loss has been incurred is remote. We have not accrued any amounts for litigation matters because of the uncertainty of the liability and inability to reasonably estimate the liability, if any. We currently believe the disposition of all claims and disputes, individually or in the aggregate, should not have a material adverse effect on our Consolidated Financial Statements, results of operations or liquidity.

Note 9 – Financial instruments:

The following table presents the financial instruments that are not carried at fair value but which require fair value disclosure:

​

Due to their near-term maturities, the carrying amounts of accounts receivable and accounts payable are considered equivalent to fair value. See Notes 3 and 5.

Note 10 – Related party transactions:

From time to time, we may have loans and advances outstanding between us and various related parties pursuant to term and demand notes. We generally enter into these loans and advances for cash management purposes. When we loan funds to related parties, we are generally able to earn a higher rate of return on the loan than we would earn if we invested the funds in other instruments, and when we borrow from related parties, we are generally able to pay a lower rate of interest than we would pay if we had incurred third-party indebtedness. While certain of these loans to affiliates

• 10 -

may be of a lesser credit quality than cash equivalent instruments otherwise available to us, we believe we have considered the credit risks in the terms of the applicable loans. In this regard, we have an unsecured revolving demand promissory note with Valhi under which, as amended, we agreed to loan Valhi up to $25 million. Our loan to Valhi, as amended, bears interest at prime plus 1.00%, payable quarterly, with all principal due on demand, but in any event no earlier than December 31, 2027. Loans made to Valhi at any time under the agreement are at our discretion. At March 31, 2026, the outstanding principal balance receivable from Valhi under the promissory note was $7.4 million. Interest income (including unused commitment fees) on our loan to Valhi was $.2 million for each of the three months ended March 31, 2025 and 2026.

Note 11 – Recent accounting pronouncements:

In November 2024, the FASB issued ASU No. 2024-03, Reporting Comprehensive Income - Expense Disaggregation Disclosures. The ASU requires additional information about specific expense categories in the notes to financial statements for both interim and annual reporting periods. The ASU is effective for us beginning with our 2027 Annual Report, and for interim reporting in the first quarter of 2028, with early adoption permitted. We are in the process of evaluating the additional disclosure requirements.

General

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. Statements in this Quarterly 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 that 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 Quarterly Report and those described from time to time in our other filings with the SEC and include, but are not limited to, the following:

• Future supply and demand for our products;
• Changes in our raw material and other operating costs (such as zinc, brass, aluminum, steel and energy costs), including as a result of additional or changed tariffs on imported raw materials, and our ability to pass those costs on to our customers or offset them with reductions in other operating costs;
• Price and product competition from low-cost manufacturing sources (such as China);
• The impact of pricing and production decisions;
• Customer and competitor strategies including substitute products;
• Our ability to retain key customers;
• Uncertainties associated with new product development and the development of new product features;
• Pending or possible future litigation (such as litigation related to our use of certain permitted chemicals in our production process) or other actions;
• 11 -
• Our ability to protect or defend our intellectual property rights;
• Decisions to sell operating assets other than in the ordinary course of business;
• Environmental matters (such as those requiring emission and discharge standards for existing and new facilities);
• The ultimate outcome of income tax audits, tax settlement initiatives or other tax matters, including future tax reform;
• Government laws and regulations and possible changes therein including new environmental, health and safety, sustainability or other regulations;
• General global economic and political conditions that disrupt our supply chain, reduce demand or perceived demand for component products or impair our ability to operate our facilities (including changes in the level of gross domestic product in various regions of the world, natural disasters, terrorist acts, global conflicts and public health crises);
• Operating interruptions (including, but not limited to, labor disputes, leaks, natural disasters, fires, explosions, unscheduled or unplanned downtime, transportation interruptions, certain regional and world events or economic conditions and public health crises);
• The introduction of new, or changes in existing, tariffs, trade barriers or trade disputes (including tariffs imposed by the U.S. government on imports from China and Mexico);
• Technology related disruptions (including, but not limited to, cyber-attacks; software implementation, upgrades or improvements; technology processing failures; or other events) related to our technology infrastructure that could impact our ability to continue operations, or at key vendors which could impact our supply chain, or at key customers which could impact their operations and cause them to curtail or pause orders; and
• Possible disruption of our business or increases in the cost of doing business resulting from terrorist activities or global conflicts.

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.

Operating Income Overview

Operating income in the first quarter of 2026 was $7.1 million compared to $5.9 million in the same period of 2025. The increase in operating income in the first quarter of 2026 compared to 2025 is primarily due to higher gross margin at Security Products and, to a lesser extent, the impact of higher sales at Marine Components.

We sell 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

Net sales. Net sales increased $.3 million in the first quarter of 2026 compared to the same period in 2025 primarily due to higher Marine Components sales to the industrial market partially offset by lower Security Products sales.

• 12 -

See segment discussion below.

Cost of sales and gross margin. Cost of sales as a percentage of net sales decreased 2.5% in the first quarter of 2026 compared to the same period in 2025. As a result, gross margin as a percentage of net sales increased over the same period. Gross margin percentage increased in the first quarter of 2026 compared to the same period in 2025 primarily due to higher gross margin percentage at Security Products. See segment 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 any gains and losses on property and equipment. Operating costs and expenses for the first quarter of 2026 were comparable to same period in 2025. Operating costs and expenses as a percentage of net sales for the first quarter of 2026 decreased slightly due to increased coverage of operating costs and expenses as a result of higher sales.

Operating income. As a percentage of net sales, operating income for the first quarter of 2026 increased compared to the same period of 2025 and was primarily impacted by the factors impacting sales, cost of sales, gross margin and operating costs and expenses. See segment discussion below.

• 13 -

Interest income. Interest income decreased $.2 million in the first quarter of 2026 compared to the same period in 2025 primarily due to lower average interest rates and decreased average investment balances.

Provision for income taxes. A tabular reconciliation of our actual tax provision to the U.S. federal statutory income tax rate is included in Note 6 to the Condensed Consolidated Financial Statements. Our operations are wholly within the U.S. and therefore our effective income tax rate is primarily reflective of the U.S. federal statutory rate and applicable state taxes.

Segment Results

Key performance indicators for our segments are gross margin and operating income.

Security Products. Security Products net sales decreased 1% in the first quarter of 2026 compared to the same period last year primarily due to lower sales across a variety of markets. The decrease was driven by $.3 million lower sales to the healthcare market and $.2 million lower sales to each of the general cabinetry, electric control panel, and gas station security markets. These decreases were partially offset by $.3 million higher sales to the tool storage market and $.2 million higher sales to the institutional furniture market. Gross margin as a percentage of net sales increased in the first quarter primarily due to a more favorable customer and product mix. Operating income margin also increased, primarily due to the improvement in gross margin discussed above.

​

Marine Components. Marine Components net sales increased 6% in the first quarter of 2026 compared to the same period last year primarily due to $1.9 million higher sales to the industrial market partially offset by $1.4 million lower sales to the towboat market. Towboat market sales in the first quarter of 2025 benefitted from a one-time customer stocking event that did not repeat in 2026. Gross margin as a percentage of net sales decreased in the first quarter of 2026 compared to the same period last year primarily due to higher cost inventory produced during the fourth quarter of 2025 and sold in the first quarter of 2026, partially offset by increased coverage of fixed costs on higher sales. Operating income margin decreased primarily due to the factors impacting gross margin discussed above, partially offset by increased coverage of operating costs and expenses on higher sales.

• 14 -

Outlook. Net sales for the first quarter of 2026 exceeded the prior year period, primarily driven by improved demand in the industrial market at Marine Components. Security Products sales reflected mixed performance across the original equipment manufacturer (“OEM”) markets, driven by differences in customer demand cycles and project timing, resulting in slightly lower net sales compared to the prior year period. Operating income increased compared to the prior year primarily due to a more favorable customer and product mix at Security Products and, to a lesser extent, the impact of higher sales at Marine Components.

For the full year 2026, we expect modest net sales growth as we continue to align pricing, product features, and service levels with market conditions and customer requirements. Net sales growth at Marine Components is expected to be driven primarily by the industrial market. Recreational marine sales have largely stabilized and sales to the towboat market in 2026 are expected to be generally comparable to 2025 (excluding the impact of the one-time stocking event noted above). At Security Products, we expect net sales to be consistent with the prior year, reflecting anticipated continued variability across multiple OEM markets.

We expect gross margin and operating income margins across both segments in 2026 to remain generally comparable to 2025. Operating income margin at Security Products benefited from favorable mix in the first quarter of 2026; however, margins are expected to moderate over the remainder of the year. We increased inventory levels across both segments during 2025 to support customer demand. These actions included an insourcing initiative at Security Products and a shift in customer mix at Marine Components. Inventory levels at the end of the first quarter of 2026 were comparable to those at December 31, 2025 and are expected to remain at these levels, consistent with near-term operating requirements.

We manufacture substantially all our products in the U.S. and source a substantial majority of our raw materials from U.S. suppliers. We also source certain components, primarily electronic components, from suppliers in Asia, including China. Beginning in the second quarter of 2025 and continuing through the first quarter of 2026, we incurred tariff-related surcharges to certain raw materials, primarily electronic components. In addition, some of our U.S.-based suppliers are applying tariff-related surcharges on certain domestically sourced materials. Where possible, we increase selling prices to recover these higher raw material costs, although the extent to which we can fully recover such costs will depend on a variety of factors including the ultimate tariff rate, duration of tariffs, and our customers’ ability to substitute alternative products. 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 experienced global and domestic supply chain challenges in the past. Any future impacts on our operations will depend on, among other things, disruption to our operations or our suppliers’ operations, the effect of tariffs, and the impact of broader economic conditions, consumer confidence, and geopolitical events affecting demand for our products or our customers’ and suppliers’ operations, all of which remain uncertain and cannot be predicted.

Liquidity and Capital Resources

Consolidated cash flows –

Operating activities. Trends in cash flows from operating activities, excluding changes in assets and liabilities, have generally been similar to the trends in operating earnings. Changes in assets and liabilities result primarily from the timing of production, sales and purchases. Changes in assets and liabilities generally tend to even out over time. However, period-to-period relative changes in assets and liabilities can significantly affect the comparability of cash flows from operating activities.

We generally report a net use of cash from operating activities in the first three months of each year due to seasonal changes in the level of our working capital. Our net cash used by operating activities for the first three months of 2026 increased by $1.0 million as compared to the first three months of 2025. The increase in net cash used is primarily due to the net effects of a $1.9 million increase in the amount of net cash used by relative changes in our inventories, receivables, prepaids, payables and non-tax related accruals in 2026 and a $1.2 million increase in operating income in 2026.

Changes in working capital can have a significant effect on cash flows from operating activities. As shown below, the change in our average days sales outstanding increased from December 31, 2025 to March 31, 2026, with changes

• 15 -

varying by segment primarily as a result of relative changes in the timing of sales and collections relative to the end of the quarter. For comparative purposes, we have provided December 31, 2024 and March 31, 2025 numbers below.

​

As shown below, our average number of days in inventory decreased from December 31, 2025 to March 31, 2026 primarily due to lower days in inventory at Marine Components driven by higher sales volumes in the first quarter of 2026 as compared to the fourth quarter of 2025. For comparative purposes, we have provided December 31, 2024 and March 31, 2025 numbers below.

Investing activities. Our capital expenditures were $.4 million and $.8 million in the first three months of 2026 and 2025, respectively. During the first three months of 2026, Valhi repaid a net $.6 million under the promissory note ($3.1 million of gross borrowings and $3.7 million of gross repayments). During the first three months of 2025, the promissory note balance with Valhi had net activity of nil ($.5 million of gross borrowings and $.5 million of gross repayments). See Note 10 to our Condensed Consolidated Financial Statements.

Financing activities. Financing activities consisted only of cash dividends. Our board of directors declared a regular quarterly dividend of $.30 per share in each of the first quarters of 2025 and 2026. 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.

Future cash requirements –

Liquidity. Our primary source of liquidity on an ongoing 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, investment activities or reducing our outstanding stock, (iii) provide for the payment of dividends (if declared), and (iv) lend to affiliates. From time-to-time, we will incur indebtedness, primarily to fund capital expenditures or business combinations.

Periodically, we evaluate 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, 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.

We believe that cash generated from operations together with cash on hand, as well as our ability to obtain external financing, will be sufficient to meet our liquidity needs for working capital, capital expenditures, debt service, dividends (if declared) and any amounts we might loan from time to time under the terms of our revolving loan to Valhi discussed in Note 10 to our Condensed Consolidated Financial Statements (which loans would be solely at our discretion) for both the next 12 months and five years. To the extent that our actual operating results or other developments differ from our expectations, our liquidity could be adversely affected.

All of our $49.4 million aggregate cash and cash equivalents at March 31, 2026 were held in the U.S.

• 16 -

Capital expenditures. Firm purchase commitments for capital projects in process at March 31, 2026 totaled $.4 million. We expect our capital expenditures for 2026 will be approximately $4.3 million primarily to improve our manufacturing facilities and invest in manufacturing equipment, including new technologies and increased automation.

Stock repurchase program. At March 31, 2026, we have 523,647 shares available for repurchase under a stock repurchase program authorized by our board of directors.
