DALLAS, TEXAS … November 5, 2025 … CompX International Inc. (NYSE American: CIX) announced today net sales of $40.0 million for the third quarter of 2025 compared to $33.6 million in the same period of 2024. Operating income was $4.8 million in the third quarter of 2025 compared to $3.3 million in the same period of 2024. Net income was $4.2 million, or $.34 per basic and diluted common share, for the third quarter of 2025 compared to $3.5 million, or $.28 per basic and diluted common share, in the same period of 2024.

For the nine months ended September 30, 2025, net sales were $120.6 million compared to $107.5 million in the previous year.

Third quarter and year-to-date 2025 net sales increased over the comparable 2024 periods due to higher Security Products sales primarily to the government security market and higher Marine Components sales to various markets including the towboat, government and industrial markets. Operating income increased in the third quarter and for the first nine months of 2025 compared to the same periods in 2024 due to higher sales and gross margin at each of the Security Products and Marine Components segments.

CompX is a leading manufacturer of security products and recreational marine components. It operates from three locations in the U.S. and employs approximately 558 people.

Forward-Looking Statements

The statements in this press release relating to matters that are not historical facts are forward-looking statements that represent management’s belief and assumptions based on currently available information. Although we believe the expectations reflected in such forward-looking statements are reasonable, we cannot give any assurances that these expectations will be correct. Such statements, by their nature, involve substantial risks and uncertainties that could significantly impact expected results, and actual future results could differ materially from those predicted. While it is not possible to identify all factors, we continue to face many risks and uncertainties.

-1-

The factors that could cause our actual future results to differ materially 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;

●

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;

●

Our ability to protect or defend our intellectual property rights;

●

Potential difficulties in integrating future acquisitions;

●

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

-2-

●

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.
