QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING

Q:What is the purpose of the annual meeting?

A:At the annual meeting, stockholders will vote on the following, as described in this proxy statement:

In addition, stockholders will vote on any other matter that may properly come before the meeting.

Table of Contents

Q:How do I vote if my shares are held through a brokerage firm or other nominee?

Brokerage firms or other nominees may not vote your shares on the election of a director nominee or proposal 2 in the absence of your specific instructions as to how to vote. We encourage you to provide instructions to your brokerage firm or other nominee regarding the voting of your shares. If you do not instruct your brokerage firm or other nominee how to vote with respect to the election of a director nominee or proposal 2, your brokerage firm or other nominee may not vote with respect to the election of such director nominee or on proposal 2 and your vote will be counted as a “broker/nominee non-vote.” “Broker/nominee non-votes” are non-votes by a brokerage firm or other nominee for shares held in a client’s account for which the brokerage firm or other nominee does not have discretionary authority to vote on a particular matter and has not received instructions from the client. How we treat broker/nominee non-votes is separately described in each of the answers below regarding what constitutes a quorum and the requisite votes necessary to elect a director nominee or approve proposal 2.

Table of Contents

Shares that are voted “abstain” or “withheld” are counted as present and entitled to vote and are, therefore, included for purposes of determining whether a quorum is present at the annual meeting.

As already discussed in the previous answer regarding how to vote shares held through a brokerage firm or other nominee, there are no proposals for the annual meeting that would allow a brokerage firm or nominee to cast a vote on uninstructed shares. If a brokerage firm or other nominee receives no instruction for the election of any director nominee and receives no instruction for proposal 2, such uninstructed shares will be counted as not entitled to cast a vote and are, therefore, not considered for purposes of determining whether a quorum is present at the annual meeting. If a brokerage firm or other nominee receives instructions on the election of at least one director nominee or on proposal 2, such instructed shares will be counted as present and entitled to cast a vote and are, therefore, included for purposes of determining whether a quorum is present at the annual meeting.

NL directly held approximately 87.3% of the outstanding shares of our class A common stock as of the record date. NL has indicated its intention to have its shares of our common stock represented at the meeting. If NL attends the meeting in person or by proxy, the meeting will have a quorum present.

Table of Contents

NL has indicated its intention to have its shares of our common stock represented at the meeting and to vote such shares FOR the election of each of the director nominees named in this proxy statement. If NL attends the meeting in person or by proxy and votes as indicated, the stockholders will elect all of the nominees named in this proxy statement to the board of directors.

NL has indicated its intention to have its shares of our common stock represented at the meeting and to vote such shares FOR this nonbinding advisory proposal. If NL attends the meeting in person or by proxy and votes as indicated, the stockholders will, by a nonbinding advisory vote, approve this proposal.

SECURITY OWNERSHIP

Ownership of CompX. The following table and footnotes set forth as of the record date the beneficial ownership, as defined by regulations of the SEC, of our class A common stock held by each individual, entity or group known to us to own beneficially more than 5% of the outstanding shares of our class A common stock, each of our directors, each of the named executive officers, and all of our current directors and executive officers as a group. See footnotes 3 and 4 below for information concerning the relationships of certain individuals and entities that may be deemed to own indirectly and beneficially more than 5% of the outstanding shares of our class A common stock. All information is taken from or based upon ownership filings made by such individuals or entities with the SEC or upon information provided by such individuals or entities.

Table of Contents

A majority of Contran’s outstanding voting stock is held directly by Ms. Simmons, Thomas C. Connelly (the husband of Ms. Simmons’ late sister) and various family trusts established for the benefit of Ms. Simmons, Mr. Connelly and their children and for which Ms. Simmons, Mr. Connelly or Mr. Connelly’s sister, as applicable, serves as trustee (collectively, the “Other Trusts”). With respect to the Other Trusts for which Mr. Connelly or his sister serves as trustee, the trustee is required pursuant to a stockholders agreement to vote the shares of Contran voting stock held in such trusts in the same manner as Ms. Simmons. Such voting rights of Ms. Simmons last through April 22, 2030 and are personal to Ms. Simmons. The remainder of Contran’s outstanding voting stock is held by the Family Trust, for which Tolleson Private Bank, a third party financial institution, serves as trustee (the “Trustee”). Ms. Simmons can appoint qualifying successor trustees of the Family Trust if the Trustee resigns or otherwise decides not to serve as trustee. The business address of the Family Trust (and the Trustee) is 5550 Preston Road, Suite B, Dallas, Texas 75205.

Ms. Simmons serves as chair of the board of directors of Contran, and two other members of Contran management also serve on the board of directors of Contran.

Contran is the holder of the sole membership interest of Dixie Rice and may be deemed to control Dixie Rice.

Ms. Simmons and the Family Trust are related to Valhi, which directly holds 82.7% of the outstanding shares of NL common stock.

Ms. Simmons and the Family Trust are related to the following entities that directly hold the following percentages of the outstanding shares of Kronos Worldwide common stock:

Ms. Simmons and the Family Trust are related to Dixie Rice, which directly holds 91.4% of the outstanding shares of Valhi common stock. NL (including a wholly owned subsidiary of NL) and Kronos Worldwide own 1,197,746 shares and 143,743 shares, respectively, of Valhi common stock. Since NL and Kronos Worldwide are majority owned subsidiaries of Valhi and pursuant to Delaware law, Valhi treats the shares of Valhi common stock that NL and Kronos Worldwide own as treasury stock for voting purposes. Pursuant to Section 13(d)(4) of the Securities Exchange Act, such shares are not deemed outstanding for the purposes of calculating the percentage ownership of the outstanding shares of Valhi common stock as of the record date in this proxy statement.

​

By virtue of the stock ownership of each of Kronos Worldwide, NL, Valhi, Dixie Rice and Contran, Ms. Simmons being a beneficiary of the Family Trust, the direct holdings of Contran voting stock by Ms. Simmons, the voting rights conferred to Ms. Simmons by a stockholders agreement relating to Contran stock, Ms. Simmons’ position as chair of the Contran board, and the Family Trust’s ownership of Contran voting stock, in each case as described above:

Ms. Simmons disclaims beneficial ownership of all shares of our class A common stock, except to the extent of her pecuniary interest in such shares, if any. The Family Trust (and the Trustee) disclaims beneficial ownership of all shares of our class A common stock except to the extent of its pecuniary interest in such shares, if any.

We understand that Contran and related entities or persons may consider acquiring or disposing of shares of our common stock through open market or privately negotiated transactions, depending upon future developments, including, but not limited to, the availability and alternative uses of funds, the performance of our common stock in the market, an assessment of our business and prospects, financial and stock market conditions and other factors deemed relevant by such entities. We may similarly consider acquisitions of shares of our common stock and acquisitions or dispositions of securities issued by related entities.

CORPORATE GOVERNANCE

Controlled Company Status, Director Independence and Committees. Because of NL’s ownership of 87.3% of the outstanding shares of our class A common stock, we are considered a controlled company under the corporate governance standards of the NYSE American. Pursuant to the corporate governance standards, a controlled company may choose not to have a majority of independent directors, independent compensation or nominations committees or charters for these committees. We have decided not to have an independent nominations committee. Our board of directors believes that the full board of directors best represents the interests of all of our stockholders and that it is appropriate for all matters that would otherwise be considered by a nominations or risk oversight committee to be considered and acted upon by the full board of directors. Applying the NYSE American director independence standards without any additional categorical standards, the board of directors has determined that Thomas E. Barry, Terri L. Herrington, Ann Manix, Gina A. Norris and Mary A. Tidlund are independent and have no material relationship with us that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. While the members of our management development and compensation committee currently satisfy the independence requirements of the NYSE American, we have chosen not to satisfy all of the NYSE American corporate governance standards for a compensation committee and not to have a charter for our management development and compensation committee.

2023 Meetings and Standing Committees of the Board of Directors. The board of directors held four meetings and took action by written consent on one occasion in 2023. Each of our incumbent directors attended all of the board meetings and meetings of the committees on which he or she served that were held while he or she was in office during 2023. It is expected that each director nominee will attend our annual meeting of stockholders, which is held immediately before the annual meeting of the board of directors. All of our directors who were elected at our 2023 annual stockholder meeting attended such meeting.

The board of directors has established and delegated authority to two standing committees, which are described below. The board of directors is expected to elect the members of the standing committees at the board of directors annual meeting immediately following the annual stockholder meeting. The board of directors from time to time may establish other committees to assist it in the discharge of its responsibilities.

Audit Committee. Our audit committee assists with the board of directors’ oversight responsibilities relating to our financial accounting and reporting processes and auditing processes, and to our management of risk. The purpose, authority, resources and responsibilities of our audit committee are more specifically set forth in its charter. Applying the requirements of the NYSE American corporate governance standards (without additional categorical standards) and SEC regulations, as applicable, the board of directors has previously determined that:

Herrington, Ann Manix, Gina A. Norris and Mary A. Tidlund. Our former director Kevin B. Kramer was a member of our audit committee until October 2023. Our audit committee held five meetings in 2023.

Management Development and Compensation Committee. The principal responsibilities of our management development and compensation committee are:

As discussed above, the board of directors has determined that each member of our management development and compensation committee is independent by applying the NYSE American director independence standards (without additional categorical standards). The management development and compensation committee may delegate to its members or our officers any or all of its authority as it may choose subject to certain limitations of Delaware law on what duties directors may delegate. The committee has not exercised this right of delegation. With respect to the role of our executive officers in determining or recommending the amount or form of executive compensation, see the Compensation Discussion and Analysis section of this proxy statement. With respect to director cash compensation, our executive officers make recommendations on such compensation directly to our board of directors for its consideration without involving the management development and compensation committee. The current members of our management development and compensation committee are Ann Manix (chair) and Thomas E. Barry. Our management development and compensation committee held one meeting in 2023.

Risk Oversight. Our board of directors oversees the actions we take in managing our material risks. Our management is responsible for our day-to-day management of risk. The board’s oversight of our material risks is undertaken through, among other things, various reports and assessments that management presents to the board and the related board discussions. The board has delegated some of its primary risk oversight to our audit committee and management development and compensation committee.

Our audit committee oversees risks associated with financial and accounting matters, including our financial reporting and internal control systems. The audit committee annually receives management’s report and assessment on the risk of fraud, and also periodically receives reports from our independent registered public accounting firm regarding, among other things, financial risks and the risk of fraud. In addition, the audit committee has responsibility for facilitating the board’s process of oversight of our overall risk management approach, and in that regard the audit committee annually receives management’s report on identification and assessment (including a ranking) of our material business risks and management’s approach for providing periodic updates to the board and applicable committees.

Our management development and compensation committee receives management’s assessments on the likelihood that our compensation policies and practices could have a material adverse effect on us, as more fully described in the Compensation Policies and Practices as They Relate to Risk Management section of this proxy statement.

The audit committee and management development and compensation committee report to the board of directors about their meetings. We believe the leadership structure of the board of directors is appropriate for our risk oversight.

Identifying and Evaluating Director Nominees. Historically, our management has recommended director nominees to the board of directors. As stated in our corporate governance guidelines:

Table of Contents

In identifying, evaluating and determining our director nominees, the board of directors follows such corporate governance guidelines. The board also considers the nominee’s ability to satisfy the need, if any, for required expertise on the board of directors or one of its committees. While we do not have any policy regarding the diversity of our nominees, the board does consider diversity in the background, skills and expertise at the policy making level of our director nominees, and as a result our board believes our director nominees do possess a diverse range of senior management experience that aids the board in fulfilling its responsibilities. The board of directors believes its procedures for identifying and evaluating director nominees are appropriate for a controlled company under the NYSE American corporate governance standards.

Leadership Structure of the Board of Directors and Independent Director Meetings. Loretta J. Feehan serves as our chair of the board (non-executive), and our chief executive officer Scott C. James serves on our board. The board of directors believes our current leadership structure is appropriate for a controlled company under the NYSE American corporate governance standards. While there is no single organizational structure that is ideal in all circumstances, the board of directors believes that having different individuals serve as our chair of the board (non-executive) and as our chief executive officer reflects the established working relationship for these positions regarding our business and provides an appropriate breadth of experience and perspective that effectively facilitates the formulation of our long-term strategic direction and business plans. In addition, the board of directors believes that since Ms. Feehan is a representative of Contran, her service as our chair of the board (non-executive) is beneficial in providing strategic leadership for us since there is a commonality of interest that is closely aligned in building long-term stockholder value for all of our stockholders. We have in the past, and may in the future, have a leadership structure in which the same individual serves as our chairman of the board and as our chief executive officer. In those instances, the individual has been, or would be expected to be, an employee or representative of Contran (or one of Contran’s subsidiaries, including us).

Pursuant to our corporate governance guidelines, our non-management directors (who are not executive officers of CompX) are entitled to meet on a regular basis throughout the year, and will meet at least once annually, without management participation. Our independent directors also meet at least once annually, without the participation of our other directors who are not independent. We are not required to have a lead independent director under the NYSE corporate governance standards. While we do not have a lead independent director, the chairman of our audit committee presides at all of the meetings of our non-management and independent directors. In 2023, we complied with the NYSE American requirements for meetings of our non-management and independent directors.

Stockholder Proposals and Director Nominations for the 2025 Annual Meeting of Stockholders. Under the rules of the SEC, in order to be considered for inclusion in next year’s proxy statement, a stockholder proposal must be received by us no later than December 10, 2024. The notice should be in writing and must comply with the proxy rules of the SEC. If the date of our 2025 annual stockholders meeting changes by more than 30 days from May 22, 2025 (the anniversary of this year’s annual meeting), then the deadline will be a reasonable time before the printing and mailing of our proxy materials in accordance with applicable SEC rules.

Our advance notice bylaw provisions require that any stockholder proposal or director nomination to be presented from the floor of our 2025 annual meeting must be received by our corporate secretary not later than the 120th day nor earlier than the 150th day prior to May 22, 2025 (the first anniversary of this year’s annual meeting). If the date of our 2025 annual meeting is more than 30 days before or after May 22, 2025, stockholder proposals must be delivered no later than the 10th day following the date that notice of the date or our annual meeting is mailed or the public disclosure of the date for such annual meeting, whichever is earlier. Any stockholder proposal must be, under law, an appropriate subject for stockholder action to be brought before the meeting. In addition, in order to present a stockholder proposal or nominate a director at our 2025 annual meeting, the stockholder must satisfy certain other requirements,

Table of Contents

including information requirements, set forth in our amended and restated bylaws. Stockholder proposals and director nominations should be directed to CompX International Inc., c/o Corporate Secretary, Three Lincoln Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240.

In addition to satisfying the foregoing requirements under our amended and restated bylaws, stockholders who intend to solicit proxies in support of director nominees other than CompX’s nominees must provide us with the notice required under Rule 14a-19 under the Securities Exchange Act by the deadline for nominations under the advance notice provisions of our bylaws (that is, in most cases no later than January 22, 2025) and comply with the other requirements of that rule.

Communications with Directors. Stockholders and other interested parties who wish to communicate with the board of directors or its non-management or independent directors may do so through the following procedures. Such communications not involving complaints or concerns regarding accounting, internal accounting controls and auditing matters related to us may be sent to the attention of our corporate secretary at CompX International Inc., Three Lincoln Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240-2620. Provided that any such communication relates to our business or affairs and is within the function of our board of directors or its committees, and does not relate to insignificant or inappropriate matters, such communication, or a summary of such communication, will be forwarded to the chairman of our audit committee, who also serves as the presiding director of our non-management and independent director meetings.

Complaints or concerns regarding accounting, internal accounting controls and auditing matters, which may be made anonymously, should be sent to the attention of our general counsel with a copy to our chief financial officer at the same address as our corporate secretary. These complaints or concerns will be forwarded to the chairman of our audit committee. We will investigate and keep these complaints or concerns confidential and anonymous, to the extent feasible, subject to applicable law. Information contained in such a complaint or concern may be summarized, abstracted and aggregated for purposes of analysis and investigation.

Compensation Committee Interlocks and Insider Participation. During 2023, Ann Manix and Thomas E. Barry served on the management development and compensation committee. No member of the committee:

For 2023, no executive officer of ours had any interlock relationships within the scope of the intent of applicable SEC rules. However, during 2023 Michael S. Simmons was an executive officer of ours and on the board of directors of Contran when concurrently also serving as one of our directors.

Code of Business Conduct and Ethics. We have adopted a code of business conduct and ethics. The code applies to all of our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer and controller. Only the board of directors may amend the code. Only our audit committee or other committee of the board of directors with specifically delegated authority may grant a waiver of this code for a director or executive officer. We intend to disclose changes to or waivers from the code by posting to our website at www.compxinternational.com (under the governance section) if disclosure is required by SEC or NYSE American rules.

Corporate Governance Guidelines. We have adopted corporate governance guidelines to assist the board of directors in exercising its responsibilities. Among other things, the corporate governance guidelines provide for director qualifications, for independence standards and responsibilities, for approval procedures for ISAs and that our audit committee chairman preside at all meetings of the non-management or independent directors.

Availability of Corporate Governance Documents. A copy of each of our audit committee charter, code of business conduct and ethics and corporate governance guidelines is available on our website at www.compxinternational.com under the governance section.

Table of Contents

Employee, Officer and Director Hedging. We have not adopted any policies or practices regarding hedging of our equity securities by our employees (including officers) or directors. However, our employees (including officers) and directors must comply with our insider trading policy, which applies to hedging transactions involving our securities as it does to transactions in our securities generally.

COMPENSATION OF EXECUTIVE OFFICERS AND DIRECTORS

AND OTHER INFORMATION

Compensation Discussion and Analysis. This compensation discussion and analysis describes the key principles and factors underlying our executive compensation policies for our named executive officers. In 2023, we employed one of our named executive officers. Contran employed and directly compensated our four other named executive officers who provided their services to us in 2023 under our ISA with Contran.

As defined in the Glossary of Terms at the beginning of this proxy statement, the phrase “named executive officers” refers to the six persons whose compensation is summarized in the 2023 Summary Compensation Table in this proxy statement. Such phrase is not intended to refer, and does not refer, to all of our executive officers.

Nonbinding Advisory Stockholder Vote on Executive Officer Compensation. For the 2023 annual meeting of stockholders, we submitted a nonbinding advisory proposal recommending the stockholders adopt a resolution approving the compensation of our named executive officers as disclosed in the 2023 proxy statement. At the annual meeting, the resolution received the affirmative vote of 90.2% of the eligible votes. We considered the favorable result and determined not to make any material changes to our compensation practices.

Compensation of our Named Executive Officer Employed by Us. We have one named executive officer employed by us. Scott C. James is our president and chief executive officer and was an executive officer and employed by us for all of the last three years.

Overview. Prior to 2021, we decided to forgo long-term compensation (other than defined contribution plans that are generally available on a non-discriminatory basis to all employees) and implemented a compensation program that is primarily cash-based, with minimal perquisites, if any. Our objectives for the primarily cash-based compensation program as it relates to our senior officers, including Mr. James, are to:

In furtherance of our objectives and in an effort to separate annual operating planning from annual incentive compensation, we implemented discretionary incentive bonuses for our senior officers. As a result, annual compensation for Mr. James primarily consists of a base salary and a discretionary incentive bonus.

We do not base Mr. James’ compensation on any specific measure of, or formula based upon, our financial performance, although we do consider our financial performance as one factor in determining his compensation. We determine the amount of each component of such compensation solely in our collective business judgment and experience, without performing any independent market research. We have not entered into any written employment agreements with Mr. James.

Base Salary. We have established Mr. James’ annual base salary based on his responsibility and experience. We pay this portion of his compensation to provide Mr. James with a reliable amount of compensation for the year, subject to his continued at-will employment and satisfactory performance for his services at the level of his responsibilities. Our vice chairman of the board conducts an annual internal review of Mr. James’ salary level and makes a recommendation on the salary to our management development and compensation committee. The committee reviews the recommendation and may take such action, including modifications to the recommendation, as it deems appropriate.

Table of Contents

The recommendation of our vice chairman and the determinations of our management development and compensation committee are based on our evaluations of the past year annual base-salary amounts with adjustments made as a result of our past and expected future financial performance, inflation, past and potential future individual performance and contributions or alternative career opportunities that might be available to Mr. James, without performing any independent market research.

In determining increases in Mr. James’ base salary for each of the last three years, we did not use any specific measure of, or formula based upon, our financial performance, although we did consider our financial performance as one factor in determining such increases. There is no specific weighting of factors in determining the increases. Mr. James’ base salary is disclosed in his salary column in the 2023 Summary Compensation Table in this proxy statement for each of the last three years.

Annual Incentive Bonus. We pay a discretionary incentive bonus annually in cash to Mr. James to motivate him to achieve higher levels of performance in attaining our corporate goals and reward him for such performance. We determine the amount of any such incentive bonus on a year-end discretionary evaluation of Mr. James’ responsibility, performance, attitude and potential. The amount of the incentive bonus is also influenced by the amount of his base salary and prior year incentive bonus, as well as our financial performance. We based our award of incentive bonuses for Mr. James primarily upon the recommendation of our vice chairman of the board and upon the determinations of our management development and compensation committee, which may take such action, including modifications to the recommendation, as it deems appropriate.

In determining Mr. James’ bonus for each of the last three years, we did not use any specific overall performance measures or any specific measure of, or formula based upon, our financial performance, although we did consider our financial performance as one factor in determining such bonuses. Additionally, there is no specific weighting of factors considered in the determination of the annual incentive bonus. We approved discretionary incentive bonuses for Mr. James in the last three years as a percentage of his base salary as follows.

The 2023 discretionary incentive bonus for Mr. James recognized, among other things, CompX’s overall strong operating performance despite softening demand in our marine components segment, and our operating cash flow generation. The 2022 discretionary incentive bonus for Mr. James recognized, among other things, substantial growth in sales and operating income in 2022 in both of our segments as compared to 2021 and the success in scaling up our marine components segment. The 2021 discretionary incentive bonus for Mr. James recognized, among other things, substantial growth in sales and operating income in 2021 in both of our segments as compared to 2020, despite industry challenges. These discretionary incentive bonuses are disclosed in the bonus column in the 2023 Summary Compensation Table in this proxy statement.

Defined Contribution Plans. We pay discretionary annual contributions to the CompX Capital Accumulation Plan, a profit sharing defined contribution plan, and The Employee 401(k) Retirement Plan, a 401(k) defined contribution plan. Participants of these plans are employees of certain of our operations. In March of each year, upon the recommendation of our chief executive officer and the approval of our management development and compensation committee, we contributed for the plan year that ended on December 31 of the prior year, subject to certain limitations under the respective plans and the U.S. Internal Revenue Code of 1986, as amended:

Table of Contents

Mr. James received such contributions for each of the last three years. These contributions are included in his all other compensation column in the 2023 Summary Compensation Table in this proxy statement.

Compensation of our Named Executive Officers Employed by Contran.  For each of the last three years, certain of our named executive officers were employed by Contran and provided their services to us pursuant to our ISA with Contran. Our named executive officers who provided services to us pursuant to our ISA with Contran are as follows:

​

​

The nature of the duties of each of our named executive officers who are employees of Contran is consistent with the duties normally associated with the officer titles and positions such officer holds with us.

Intercorporate Services Agreement with Contran. We pay Contran a fee for services provided pursuant to our ISA with Contran, which fee was approved by our independent directors after receiving the recommendation of our management development and compensation committee and the concurrence of our chief financial officer. Such services provided under this ISA included the services of our named executive officers employed by Contran, and as a result a portion of the aggregate ISA fee we pay to Contran is paid with respect to services provided to us by such named executive officers. The nature of the duties of each of our executive officers who are employees of Contran is consistent with the duties normally associated with the officer titles and positions such officer holds with us.

The charge under this ISA reimburses Contran for its cost of employing the personnel who provide the services by allocating such cost to us based on the estimated percentage of time such personnel were expected to devote to us over the year. The amount of the fee we paid for each year under this ISA for a person who provided services to us represents, in management’s view, the reasonable equivalent of “compensation” for such services. See the Intercorporate Services Agreements part of the Certain Relationships and Transactions section of this proxy statement for the aggregate amount we paid to Contran in 2023 under this ISA. Under the various ISAs among Contran and its subsidiaries and affiliates, we shared the cost of the employment of our executive officers employed by Contran with Contran and certain of its other publicly and privately held subsidiaries. For our named executive officers employed by Contran, the portion of the annual charge we paid for each of the last three years to Contran under this ISA attributable to each of their services, as applicable, is set forth in the 2023 Summary Compensation Table in this proxy statement. As discussed further below, the amount charged under the ISA is based upon Contran’s cost of employing or engaging the personnel who provide the services to us (including the services of our named executive officers employed by Contran) by allocating such cost to us based on the estimated percentage of time such personnel were expected to devote to us over the year. The amount charged under the ISA is not dependent upon our financial performance.

We believe the cost of the services received under our ISA with Contran, after considering the quality of the services received, is fair to us and is no less favorable to us than we could otherwise obtain from an unrelated third party for comparable services, based solely on our collective business judgment and experience without performing any independent market research.

In the early part of each year, Contran’s management, including certain of our executive officers, estimates the percentage of time that each Contran employee, including certain of our named executive officers, is expected to devote in the upcoming year to Contran and its subsidiaries and affiliates, including us. Contran’s management then allocates Contran’s cost of employing each of its employees among Contran and its various subsidiaries based on such estimated percentages. Contran’s aggregate cost of employing each of its employees comprises:

Table of Contents

Contran’s senior management subsequently make such adjustments to the details of the proposed ISA charge as they deem necessary for accuracy, overall reasonableness and fairness to us.

In the first quarter of each year reported in the 2023 Summary Compensation Table, the proposed charge for that year under our ISA with Contran was presented to our management development and compensation committee, and the committee considered whether to recommend that our board of directors approve the ISA charge. Among other things during such presentation, the committee was informed of:

In determining whether to recommend that the board of directors approve the proposed ISA fee to be charged to us, the management development and compensation committee considers the three elements of Contran’s cost of employing the personnel who provide services to us, as discussed above, including the cost of employing certain of our named executive officers, in the aggregate and not individually. After considering the information contained in such presentations, and following further discussion and review, our management development and compensation committee recommended that our board of directors approve the proposed ISA fee after concluding, based on their collective business judgment and experience without performing any independent market research, that:

In reaching its recommendation, our management development and compensation committee did not review:

Table of Contents

Based on the recommendation of our management development and compensation committee as well as the concurrence of our chief financial officer, our independent directors approved the proposed annual ISA charge effective January 1, 2023, with our other directors abstaining.

For financial reporting and income tax purposes, the ISA fee is expensed as incurred on a quarterly basis. Section 162(m) of the Code generally disallows an income tax deduction to publicly held companies for compensation over $1.0 million paid to the company’s chief executive officer, chief financial officer and three other most highly compensated executive officers. To the extent any individual’s charge to a publicly held company under the ISA was in excess of $1.0 million, the deductibility by the company of the charge for income tax purposes would be limited under Section 162(m), if such section were to be deemed applicable as it relates to the ISA. In 2021, 2022 and 2023 the ISA did not include, and in 2024 the ISA will not include, charges in excess of $1.0 million for any individual. In the event the fee we would pay to Contran under our ISA with Contran were ever to include the services for any individual with an ISA charge in excess of $1.0 million, Contran has agreed to absorb the impact of any such income tax deduction disallowance.

No Director Fees or Equity-Based Compensation for Executive Officers.  Our executive officers, including our named executive officers, are not eligible to receive cash or equity-based compensation for their service on our board of directors. For the years reflected in the 2023 Summary Compensation Table, we did not pay any compensation to Mr. James or Mr. Simmons for their service as one of our directors.

Prior to 2021, we decided to forgo the grant of any equity compensation other than annual awards of stock to our directors, as discussed above. We also do not have any security ownership requirements or guidelines for our management, although we do have stock ownership guidelines for our non-employee directors. We do not currently anticipate any equity-based compensation will be granted in 2024, other than the annual grants of stock to our directors who are not employees of Contran or one of its subsidiaries or affiliates.

Compensation Committee Report. The management development and compensation committee has reviewed with management the Compensation Discussion and Analysis section in this proxy statement. Based on the committee’s review and a discussion with management, the committee recommended to the board of directors that our compensation discussion and analysis be included in this proxy statement.

The members of our management development and compensation committee submit the foregoing report as of February 28, 2024.

Summary of Cash and Certain Other Compensation of Executive Officers. The 2023 Summary Compensation Table below provides information concerning compensation we and our subsidiaries paid or accrued for services rendered during the last three years by our chief executive officer, our chief financial officer, and each of the three other most highly compensated individuals (based on ISA charges to us) who were our executive officers at December 31, 2023. Other than Mr. James, all of our named executive officers were employees of Contran for their years reported in this table and provided their services to us and our subsidiaries pursuant to our ISA with Contran. For a discussion of this ISA, see the Intercorporate Services Agreements part of the Certain Relationships and Transactions section of this proxy statement.

2023 Summary Compensation (1)

​

Table of Contents

See the discussion of our retirement plan contributions in the Compensation Discussion and Analysis section of this proxy statement.

No Grants of Plan-Based Awards. During 2023, no named executive officer received any plan-based awards from us or our subsidiaries.

No Outstanding Equity Awards at December 31, 2023. At December 31, 2023, none of our named executive officers held outstanding stock options to purchase shares of our class A common stock (or common stock of our parent companies), or held any equity incentive awards for such shares.

No Option Exercises or Stock Vested. During 2023, no named executive officer exercised any stock options or held any stock subject to vesting restrictions.

Pension Benefits. We do not have any defined benefit pension plans in which our named executive officers participate.

Nonqualified Deferred Compensation. We do not owe any nonqualified deferred compensation to our named executive officers.

Pay Ratio Disclosure. SEC rules require annual disclosure of the ratio of a registrant’s median employee’s annual total compensation to the total annual compensation of its chief executive officer.  For 2023, the total annual compensation (as disclosed in the 2023 Summary Compensation Table) of Scott C. James, our chief executive officer, is $1,315,477; the reasonable estimate of the median of the annual total compensation of all of our employees except our chief executive officer, calculated in a manner consistent with Item 402(u) of Regulation S-K, is $49,934; and the ratio of such two amounts is 26 to 1.

For purposes of this disclosure, our “median employee” was estimated using a simple random sample statistical sampling technique, pursuant to which we and each of our consolidated subsidiaries selected every seventh employee listed on their first payroll register for the month of October 2023. Based on such random sample of our employees, and using the 2023 base salary (or equivalent for hourly employees) for each employee in such random sample as reflected in our payroll records, the median employee was estimated by determining the employee in such random sample who had the median 2023 base salary (or equivalent for hourly employees). Base salary (or equivalent) amounts were annualized for any employee who had less than a full year of service during 2023.

​

Table of Contents

Director Compensation. Our directors who are not employees of Contran or one of its subsidiaries or affiliates (including us) are eligible to receive compensation for service as directors. The table below reflects the annual rates of their retainers for 2023.

​

Additionally, our eligible directors receive a fee of $1,000 per day for attendance at meetings of the board of directors or its committees and an hourly rate (not to exceed $1,000 per day) for other services rendered on behalf of our board of directors or its committees. If a non-employee director who was first elected to our board prior to 2022 dies while serving on our board of directors, his or her designated beneficiary or estate will be entitled to receive a death benefit equal to the annual retainer then in effect. We reimburse our directors for reasonable expenses incurred in attending meetings and in the performance of other services rendered on behalf of our board of directors or its committees.

As preapproved by our management development and compensation committee, on the day of each of our annual stockholder meetings, each of our eligible directors elected on that day receives a grant of shares of our common stock under our 2012 Director Stock Plan, with the number of shares received by each eligible director equal in value to $20,000 (rounded up or down to the nearest 50 shares), based on the closing price of a share of our common stock on the date of grant, but not more than 10,000 shares. These shares are fully vested and tradable immediately on their date of grant, other than restrictions under applicable securities laws. Our corporate governance guidelines include stock ownership guidelines for our non-employee directors (that is, directors who are not employed by us or one of our affiliates), which provide that non-employee directors may not sell shares of our common stock acquired as part of the annual stock grants unless, immediately after any such sale, they will hold a number of shares of our common stock (including shares owned by their immediate family members residing in the same household) having a value of at least three times our base annual cash retainer for service as a director.

Compensation Consultants. Neither our board of directors, management development and compensation committee nor management has engaged any compensation consultants.

​

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act requires our executive officers, directors and persons who own more than 10% of a registered class of our equity securities to file reports of ownership with the SEC, the NYSE American and us. Based solely on the review of the copies of such forms and representations by certain reporting persons, we believe that for 2023 our executive officers, directors and 10% stockholders complied with all applicable filing requirements under section 16(a).

​

CERTAIN RELATIONSHIPS AND TRANSACTIONS

Related Party Transaction Policy. From time to time, we engage in transactions with affiliated companies. Pursuant to our Policy Regarding Related Party Transactions, or RPT Policy, all related party transactions (as defined in the RPT Policy) to which we are or are proposed to be a party are approved or (where permitted) ratified by our audit committee (unless another committee of our board of directors composed solely of independent directors, or all of the

Table of Contents

independent directors of our board, shall have approved the related party transaction). For certain ongoing related party transactions to which we are a party (referred to as ordinary course of business related party transactions), such approval or ratification shall occur no less frequently than once a year. The RPT Policy is available on our website at www.compxinternational.com under the governance section.

During 2023, our audit committee reviewed and approved the following ordinary course of business related party transactions to which we are a party in accordance with the terms of such RPT Policy, each of which was part of an ongoing program or agreement that had been previously approved:

Each of these ordinary course of business related party transactions, and the actions taken by the audit committee in fulfilling its duties and responsibilities under the RPT Policy, are more fully described below.  Our audit committee was not required to approve the fee we paid to Contran in 2023 under our intercorporate services agreement with Contran, because such intercorporate services fee is approved by all of the independent directors of our board, as more fully described below. During 2023, we were not a party to any other related party transactions (ordinary course of business related party transactions or otherwise) requiring approval or ratification under the RPT Policy.

Relationships with Related Parties. As set forth under the Security Ownership section of this proxy statement, Lisa K. Simmons and the Family Trust may be deemed to control us. We and other entities that may be deemed to be controlled by or related to Ms. Simmons and the Family Trust sometimes engage in the following:

We periodically consider, review and evaluate and understand that Contran and related entities periodically consider, review and evaluate such transactions. Depending upon the business, tax and other objectives then relevant and restrictions under indentures and other agreements, it is possible that we might be a party to one or more of such transactions in the future. In connection with these activities, we may consider issuing additional equity securities or incurring additional indebtedness. Our acquisition activities have in the past and may in the future include participation in acquisition or restructuring activities conducted by other companies that may be deemed to be related to Ms. Simmons and the Family Trust.

Certain directors or executive officers of Contran, NL, Kronos or Valhi also serve as our directors or executive officers. Such relationships may lead to possible conflicts of interest. These possible conflicts of interest may arise under circumstances in which such companies may have adverse interests. In such an event, we implement such procedures as are appropriate for the particular transaction and as are consistent with the provisions of the RPT Policy.

Table of Contents

Intercorporate Services Agreements. As discussed elsewhere in this proxy statement, we and certain related companies have entered into ISAs. Under the ISAs, employees of one company provide certain services, including executive officer services, to the other company on an annual fixed fee basis. The services rendered under the ISAs may include executive, management, financial, internal audit, accounting, tax, legal, insurance, insurance claims management, risk management, real estate management, environmental management, treasury, human resources, technical, consulting, administrative, office, occupancy and other services as required from time to time in the ordinary course of the recipient’s business. The fees paid pursuant to the ISAs are generally based upon an estimated percentage of the time devoted by employees of the provider of the services to the business of the recipient and the employer’s cost related to such employees, which includes the expense for the employees’ compensation and an overhead component that takes into account other employment related costs. Generally, each of the ISAs renews on a quarterly basis subject to termination by either party pursuant to a written notice delivered 30 days prior to the start of the next quarter. Because of the number of companies related to Contran and us, we believe we benefit from cost savings and economies of scale gained by not having certain management, financial, legal, tax, real estate and administrative staffs duplicated at each company, thus allowing certain individuals to provide services to multiple companies. With respect to a publicly held company that is a party to an ISA, the ISA and the related aggregate annual charge are approved by the independent directors of the company after receiving the recommendation from the company’s management development and compensation committee as well as the concurrence of the chief financial officer. See the Compensation of our Named Executive Officers Employed by Contran part of the Compensation Discussion and Analysis section in this proxy statement for a more detailed discussion on the procedures and considerations taken by our independent directors in approving the aggregate 2023 fee charged to us under our ISA with Contran.

In 2023, we paid Contran fees of approximately $3.1 million for its services under our ISA with Contran, including amounts for the services of certain of our named executive officers that are employees of Contran, as disclosed in the 2023 Summary Compensation Table in this proxy statement. In 2024, we expect to pay Contran fees of approximately $3.2 million for its services under this ISA, including the services of certain of our named executive officers that are employees of Contran.

Risk Management Program. We and Contran participate in a combined risk management program. Pursuant to the program, Contran and certain of its subsidiaries and related entities, including us and certain of our subsidiaries and related entities, as a group purchase insurance coverage and risk management services. The program apportions its costs among the participating companies.

Tall Pines is a captive insurance company wholly owned by Valhi that underwrites certain insurance policies to Contran and certain of its subsidiaries and related entities, including us. Tall Pines purchases reinsurance from highly rated (as determined by A.M. Best or other internationally recognized ratings agency) third-party insurance carriers for substantially all of the risks it underwrites. Consistent with insurance industry practices, Tall Pines receives commissions from reinsurance underwriters and/or assesses fees for certain of the policies that it underwrites. Insurance policies that are not underwritten by Tall Pines are purchased from third-party insurance carriers with an A.M. Best Company rating of generally at least an “A-” (excellent) or equivalent rating.

With respect to certain of such jointly owned insurance policies, it is possible that unusually large losses incurred by one or more insureds during a given policy period could leave the other participating companies without adequate coverage under that policy for the balance of the policy period. As a result, and in the event that the available coverage under a particular policy would become exhausted by one or more claims, Contran and certain of its subsidiaries and affiliates, including us, have entered into a loss sharing agreement under which any uninsured loss arising because the available coverage had been exhausted by one or more claims will be shared ratably by those entities that had submitted claims under the relevant policy.  We believe the benefits in the form of reduced premiums and broader coverage associated with the group coverage for such policies justify the risk associated with the potential for any uninsured loss.

Following NL’s sale of EWI’s insurance and risk management business to a third party in November 2019, the third-party brokerage and risk management company that purchased the business became the broker for Contran’s and our insurance policies and Tall Pines’ reinsurance policies and provides risk management services for Contran and its subsidiaries, including us. Accordingly, Contran and its subsidiaries and affiliates participating in the combined risk management program continue to have access to the experienced risk management personnel formerly with EWI, including in the areas of loss controls and claims management.

Table of Contents

During 2023, we paid approximately $3.4 million under the combined risk management program. This amount principally represents premiums and fees for insurance, including approximately $1.1 million for policies underwritten by Tall Pines. The full amount also includes reimbursements to insurers or reinsurers of claims within our applicable deductible or retention ranges that such insurers and reinsurers paid to third parties on our behalf, as well as amounts for risk management services and various other third-party fees and expenses incurred by the program. We expect that these relationships will continue in 2024.

In November 2023, our management made a presentation to our audit committee regarding our participation in the combined risk management program. Among other things during such presentation, the committee was informed of the following (in addition to the matters described above):

As part of such presentations, our chief financial officer, after consultation with other members of our management, advised the committee of her belief that our participation in the risk management program, including the allocation of its costs among us and the other entities participating in the risk management program, is fair and reasonable to us, and is on terms no less favorable than we could otherwise obtain from unrelated parties. She then provided the committee with her recommendation that the committee reapprove, adopt and ratify our participation in the risk management program in all respects.

After considering the information contained in the presentations, including the recommendation of our chief financial officer, and following further discussion and review by the audit committee, our audit committee determined that our participation in the risk management program is fair and reasonable to us, and is on terms no less favorable than we could otherwise obtain from unrelated parties, in each case based on the collective business judgment and experience of members of the committee, and the committee reapproved, adopted and ratified our participation in the risk management program in all respects.

Tax Matters. We and our qualifying subsidiaries are members of the consolidated U.S. federal tax return of which Contran is the parent company, which we refer to as the “Contran Tax Group.” We are also a party to a tax sharing agreement with Contran and NL. As a member of the Contran Tax Group and pursuant to the tax sharing agreement, we and our qualifying subsidiaries compute our provision for U.S. income taxes on a separate company basis using tax elections made by Contran. Pursuant to the tax sharing agreement and using tax elections made by Contran, we make payments to or receive payments from NL in amounts we would have paid to or received from the U.S. Internal Revenue Service had we not been a member of the Contran Tax Group but instead had been a separate taxpayer.

Table of Contents

Refunds are limited to amounts previously paid under the tax sharing agreement. We and our qualifying subsidiaries are also a part of consolidated tax returns filed by Contran in certain U.S. state jurisdictions, and the terms of the tax sharing agreement also apply to state payments to these jurisdictions.

Under applicable law, we, as well as every other member of the Contran Tax Group, are each jointly and severally liable for the aggregate federal income tax liability of Contran and the other companies included in the group for all periods in which we are included in the group. Under our tax sharing agreement with NL, NL has agreed to indemnify us for any liability for income taxes of the Contran Tax Group in excess of our tax liability previously computed and paid by us in accordance with the tax sharing agreement.

Under certain circumstances, tax regulations could require Contran to treat items differently than we would have treated them on a stand-alone basis. In such instances, accounting principles generally accepted in the United States of America require us to conform to Contran’s tax elections. For 2023, pursuant to our tax sharing agreement, we made net cash payments for income taxes to NL of approximately $7.3 million.

In March 2023, our management made a presentation to our audit committee regarding our tax sharing agreement with Contran and NL. Among other things during such presentation, the committee was informed of the following (in addition to the matters described above):

As part of such presentation, our chief financial officer and our vice president, tax advised the committee of their belief that the terms of the tax sharing agreement are consistent with the terms of applicable law and regulations, and are fair and reasonable to us, and are on terms no less favorable than would be present if we were not a party to the tax sharing agreement, and provided the committee with their recommendation that the committee approve, adopt and ratify the tax sharing agreement in all respects.

After considering the information contained in the presentations, including the recommendation of our chief financial officer and vice president, tax, and following further discussion and review by the audit committee, our audit committee determined that the terms of the tax sharing agreement are fair and reasonable to us and on terms no less favorable than would be present if we were not a party to the tax sharing agreement, in each case based on the collective business judgment and experience of members of the committee, and the committee approved, adopted and ratified the tax sharing agreement in all respects.

Related Party Loans for Cash Management Purposes. From time to time, loans and advances are made between us and various related parties pursuant to term and demand notes. These loans and advances are entered into principally for cash management purposes pursuant to our cash management program. 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 the funds were invested in other instruments. While certain of such loans may be of a lesser credit quality than cash equivalent instruments otherwise available to us, we believe that we have evaluated the credit risks involved, and that those risks are reasonable and reflected in the terms of the applicable loans. When we have outstanding indebtedness, we may still decide to enter into a loan to a related party either because the interest rate on the loan to the related party is at a higher rate of return as compared to the interest rate we are paying on our outstanding indebtedness, or the funds we would be loaning to the related party would not otherwise be used to pay down the outstanding indebtedness (such as, for example, in the case when the outstanding indebtedness has a maturity longer than the maturity of the loan to the related party). When we borrow from related parties, we are generally able to pay a lower rate of interest than we would pay if we borrowed from unrelated parties.

​

During 2023, we had an unsecured revolving promissory note with Valhi whereby we agreed to loan Valhi up to $25 million, bearing interest at the prime rate plus 1.00% (9.5% at December 31, 2023), payable quarterly, with all principal and unpaid interest due on demand, but in any event no earlier than December 31, 2024. At December 31, 2023, this unsecured revolving promissory note was amended, per prior general authorization from our audit committee,

Table of Contents

to extend the demand period to no earlier than December 31, 2025. The agreement contains no financial covenants or other financial restrictions. Loans made to Valhi at any time under the agreement are at our discretion. During our fiscal year ended January 1, 2024, we made aggregate loans to Valhi of $27.9 million, Valhi repaid an aggregate of $30.5 million, and the largest amount of principal outstanding under the loan was $13.9 million. At December 31, 2023, the outstanding balance of such loan to Valhi was $10.6 million. During 2023, we earned aggregate interest under this note (including unused commitment fees) of approximately $1.2 million.

​

In March 2023, our management made a presentation to our audit committee regarding our loan to Valhi. Among other things during such presentation, the committee was informed of the following (in addition to the matters described above):

As part of such presentation, our chief financial officer, after consultation with our treasurer and other members of our management, advised the committee of her belief that the terms of our loan to Valhi are fair and reasonable to us, and are on terms no less favorable than we could otherwise obtain from unrelated parties, and provided the committee with his recommendation that the committee approve, adopt and ratify our loan to Valhi, as most recently amended, in all respects.

After considering the information contained in the presentation, including the recommendation of our chief financial officer, and following further discussion and review by the audit committee, our audit committee determined that the terms of our loan to Valhi are fair and reasonable to us, and are on terms no less favorable than we could otherwise obtain from unrelated parties, in each case based on the collective business judgment and experience of members of the committee, and the committee approved, adopted and ratified our loan to Valhi in all respects.

AUDIT COMMITTEE REPORT

Our audit committee of the board of directors is composed of five directors and operates under a written charter adopted by the board of directors. All members of our audit committee meet the independence standards established by the board of directors and the NYSE American and promulgated by the SEC under the Sarbanes-Oxley Act of 2002. Two members of our audit committee meet the audit committee financial expert requirements under the applicable SEC rules. The audit committee charter is available on our website at www.compxinternational.com under the governance section.

Our management is responsible for, among other things, preparing our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America, or “GAAP,” establishing and maintaining internal control over financial reporting (as defined in Securities Exchange Act Rule 13a-15(f)) and evaluating the effectiveness of such internal control over financial reporting. Our independent registered public accounting firm is responsible for auditing our consolidated financial statements in accordance with the standards of the PCAOB and for expressing an opinion on the conformity of the financial statements with GAAP.

Our audit committee assists the board of directors in fulfilling its responsibility to oversee management’s implementation of our financial reporting process and the audit of our consolidated financial statements. Our audit committee is directly responsible for the appointment, compensation, retention and oversight of our independent registered public accounting firm. As part of fulfilling this responsibility, our audit committee engages in an annual evaluation of, among other things, the firm’s qualifications, competence, integrity, expertise, performance, independence and communications with the committee (including these factors as they relate specifically to the firm’s lead audit engagement partner), and whether the current firm should be retained for the upcoming year’s audit. Our audit committee discusses with our independent registered public accounting firm the overall scope and plans for the audit they will perform, and the committee meets with the firm throughout the year, both with and without management being present, to monitor the firm’s execution of and results obtained from their audit. Our audit committee performs other activities throughout the year, in accordance with the responsibilities of the audit committee specified in the audit committee charter, including the oversight of the performance of internal audit and the approval or ratification of certain related party transactions in accordance with the terms of our RPT Policy, as discussed above in the Certain Relationships and Transactions section in this proxy statement.

In its oversight role, our audit committee reviewed and discussed our audited consolidated financial statements with management and with PwC, our independent registered public accounting firm for 2023. Our audit committee also reviewed and discussed our internal control over financial reporting with management and with PwC. Management and PwC indicated that our consolidated financial statements as of and for the year ended December 31, 2023 were fairly stated in accordance with GAAP. Our audit committee discussed with PwC and management the significant accounting policies used and significant estimates made by management in the preparation of our audited consolidated financial statements, and the overall quality of management’s financial reporting process. Our audit committee and PwC also discussed any issues deemed significant by PwC or the committee, including the matters required to be discussed pursuant to the standards of the PCAOB, the rules of the SEC and other applicable regulations. PwC has provided to our audit committee written disclosures and the letter required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the audit committee concerning independence, and our audit committee discussed with PwC the firm’s independence. Our audit committee also concluded that PwC’s provision of other permitted non-audit services to us and our related entities is compatible with PwC’s independence.

Based upon the foregoing considerations, our audit committee recommended to the board of directors that our audited consolidated financial statements be included in our 2023 Annual Report on Form 10-K for filing with the SEC.

The members of our audit committee respectfully submit the foregoing report as of February 28, 2024.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM MATTERS

Independent Registered Public Accounting Firm. PwC served as our independent registered public accounting firm for the year ended December 31, 2023. Our audit committee has appointed PwC to review our quarterly unaudited condensed consolidated financial statements to be included in our Quarterly Report on Form 10-Q for the first quarter of 2024. We expect PwC will be considered for appointment to:

Representatives of PwC are not expected to attend our 2024 annual stockholder meeting.

Fees Paid to PricewaterhouseCoopers LLP. The following table shows the aggregate fees that our audit committee has authorized and PwC has billed or is expected to bill to us for services rendered for 2022 and 2023. Additional fees for 2023 may subsequently be authorized and paid to PwC, in which case the amounts disclosed below for fees paid to PwC for 2023 would be adjusted to reflect such additional payments in our proxy statement relating to next year’s annual stockholder meeting. In this regard, we have similarly adjusted the audit fees shown for 2022 from the amounts disclosed in our 2023 proxy statement.

Preapproval Policies and Procedures. For the purpose of maintaining the independence of our independent registered public accounting firm, our audit committee has adopted policies and procedures for the preapproval of audit and other permitted services the firm provides to us or any of our subsidiaries. We may not engage the firm to render any audit or other permitted service unless the service is approved in advance by our audit committee pursuant to the committee’s preapproval policy. Pursuant to the policy:

These other permitted services include:

The policy also lists certain services for which the independent auditor is always prohibited from providing us under applicable requirements of the SEC or the PCAOB.

Pursuant to the policy, our audit committee has delegated preapproval authority to the chairman of the committee or his designee to approve any fees in excess of the annual preapproved limits for these categories of other permitted services provided by our independent registered public accounting firm. The chairman must report any action taken pursuant to this delegated authority at the next meeting of the committee.

For 2023, our audit committee preapproved all of PwC’s services provided to us or any of our subsidiaries in compliance with our preapproval policy without the use of the SEC’s de minimis exception to such preapproval requirement.

PROPOSAL 2

NONBINDING ADVISORY RESOLUTION ON NAMED EXECUTIVE OFFICER COMPENSATION

Background. Pursuant to Section 14A of the Securities Exchange Act, a publicly held company is required to submit to its stockholders a nonbinding advisory vote to approve the compensation of its named executive officers, commonly known as a “Say-on-Pay” proposal. At our 2023 annual meeting our stockholders approved, on a nonbinding advisory basis, an annual frequency for this Say-on-Pay proposal. After the 2024 annual meeting of stockholders, the next nonbinding stockholder advisory vote on a Say-on-Pay proposal will be at our 2025 annual meeting of stockholders. The next nonbinding stockholder advisory vote on the frequency of a Say-on-Pay proposal will be at our 2029 annual meeting of stockholders.

Say-on-Pay Proposal. This proposal affords our stockholders the opportunity to submit a nonbinding advisory vote on our named executive officer compensation. The Compensation Discussion and Analysis section, the tabular disclosure regarding our named executive officer compensation and the related disclosure in this proxy statement describe our named executive officer compensation and the compensation decisions made by our management and our management development and compensation committee of the board of directors with respect to our named executive officers. This proposal is not intended to address any specific element of compensation of our named executive officers as described in this proxy statement, but the compensation of our named executive officers in general. Our board of directors requests that each stockholder cast a nonbinding advisory vote to adopt the following resolution:

RESOLVED, that, by the affirmative vote of the holders of the majority of the class A shares of common stock present in person or represented by proxy at the 2024 annual stockholder meeting and entitled to vote on the subject matter, the stockholders of CompX International Inc. approve, on a nonbinding advisory basis, the compensation of its executive officers named in the 2023 Summary Compensation Table in the 2024 annual meeting proxy statement of CompX International Inc. as such compensation is disclosed in the proxy statement pursuant to the executive compensation disclosure rules of the U.S. Securities and Exchange Commission, which disclosure includes the compensation discussion and analysis, the compensation tables and any related disclosure in the proxy statement.

Effect of the Proposal. The Say-on-Pay proposal is nonbinding and advisory. Our stockholders’ approval or disapproval of this proposal will not require our board of directors, its management development and compensation committee or our management to take any action regarding our executive compensation practices.

Vote Required. Because this proposal is a nonbinding advisory vote, there is no minimum requisite vote to approve the Say-on-Pay proposal. The proposed resolution provides that the nonbinding affirmative vote of the holders of the majority of the class A shares of common stock present in person or represented by proxy at the 2024 annual meeting and entitled to vote on the subject matter will be the requisite vote to adopt the resolution and approve the compensation of our named executive officers as such compensation is disclosed in this proxy statement. Accordingly, abstentions will be counted as represented and entitled to vote and will therefore have the effect of a negative vote. Broker/nominee non-votes, if any, will not be counted as entitled to vote and will have no effect on this proposal.

NL has indicated its intention to have its shares of our common stock represented at the meeting and to vote such shares FOR the Say-on-Pay proposal and adoption of the resolution that approves the compensation of our named executive officers as described in this proxy statement. If NL attends the meeting in person or by proxy and votes as indicated, the meeting will have a quorum present and the stockholders will adopt the resolution and approve the nonbinding advisory Say-on-Pay proposal.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE SAY-ON-PAY PROPOSAL AS SET FORTH IN THE NONBINDING ADVISORY RESOLUTION APPROVING OUR NAMED EXECUTIVE OFFICER COMPENSATION AS DISCLOSED IN THIS PROXY STATEMENT.
