Our principal executive offices are located at Three Lincoln Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240-2620.

Please refer to the Glossary of Terms on page iii for the definitions of certain terms used in this proxy statement.

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING

Table of Contents

In addition, shareholders will vote on any other matter that may properly come before the meeting or any adjournment or postponement thereof.

Table of Contents

Brokerage firms or other nominees may not vote your shares on the election of a director nominee or proposal 2 (Say-on-Pay), proposal 3 (Reincorporation Proposal), proposal 4 (Opt Out Proposal) or proposal 5 (Adjournment Proposal) 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, 3, 4 or 5, your brokerage firm or other nominee may not vote with respect to the election of such director nominee or on proposal 2, 3, 4 or 5, 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, 3, 4 or 5.

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 2026 annual meeting that would allow a brokerage firm or nominee to vote 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, 3, 4 or 5, such uninstructed shares will be counted as not entitled to 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 at least one of proposal 2, 3, 4 or 5, such instructed shares will be counted as present and entitled to vote and are, therefore, included for purposes of determining whether a quorum is present at the annual meeting.

Valhi directly held approximately 82.7% of the outstanding shares of our common stock as of the record date. Valhi has indicated its intention to have its shares of our common stock represented at the meeting. If Valhi attends the meeting in person or by proxy, the meeting will have a quorum present.

Valhi 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 Valhi attends the meeting in person or by proxy and votes as indicated, the shareholders will elect all of the nominees named in this proxy statement to the board of directors.

Valhi 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 Valhi attends the meeting in person or by proxy and votes as indicated, the shareholders will, by a nonbinding advisory vote, approve this proposal.

Table of Contents

shares of our common stock were issued and outstanding, and 40,387,531 of those were beneficially owned by Valhi.

Valhi has indicated its intention to have its shares of our common stock represented at the meeting and to vote such shares FOR the Reincorporation Proposal. If Valhi attends the meeting in person or by proxy and votes as indicated, the Basic Vote Condition will be satisfied. However, the Minority Vote Condition requires at least 5,650,136 shares not owned by Valhi to vote for the Reincorporation Proposal, in order for the proposal to be approved.

Abstentions and broker/nominee non-votes will have the same effect as a vote against the Reincorporation Proposal for purposes of the Minority Vote Condition, but will have no effect on the Basic Vote Condition.

Valhi has indicated its intention to have its shares of our common stock represented at the meeting and to vote such shares FOR the Opt Out Proposal and FOR (if it is presented for a vote) the Adjournment Proposal. If Valhi attends the meeting in person or by proxy and votes as indicated, the shareholders will approve the Opt Out Proposal and (if it is presented for a vote at the meeting) the Adjournment Proposal.

In addition to the mailing of these proxy materials, the solicitation of proxies or votes may be made in person, by telephone or by electronic communication by our directors, officers and employees, who will not receive any additional compensation for such solicitation activities. In addition, we may reimburse brokerage firms and other persons representing beneficial owners of shares for their expenses in forwarding solicitation material to such beneficial owners.

CONTROLLING SHAREHOLDER

Valhi is the direct holder of approximately 82.7% of the outstanding shares of our common stock as of the record date. Valhi 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 and FOR proposal 2 (Say-on-Pay), proposal 3 (Reincorporation Proposal), proposal 4 (Opt Out Proposal) and (if necessary) proposal 5 (Adjournment Proposal). If Valhi attends the meeting in person or by proxy and votes as indicated, the meeting will have a quorum present and the shareholders will elect all of the nominees named in this proxy statement to the board of directors and will approve proposal 2, proposal 4, and (if necessary) proposal 5, and will approve the Basic Vote Condition with respect to proposal 3. Valhi’s presence and vote at the meeting will have no effect on the outcome of the Minority Vote Condition under proposal 3.

The following table and footnotes set forth as of the record date the beneficial ownership, as defined by regulations of the SEC, of our common stock held by each individual, entity or group known to us to own beneficially more than 5% of the outstanding shares of our 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 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.

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 the Family Trust, for which Tolleson Private Bank, a third-party financial institution, serves as trustee (the “Trustee”).

​

Ms. Simmons and the Family Trust are related to Dixie Rice, which directly holds 91.4% of the outstanding shares of Valhi common stock. We (including a wholly owned subsidiary of ours) and Kronos Worldwide own 1,197,746 shares and 143,743 shares, respectively, of Valhi common stock. Since we and Kronos Worldwide are majority owned subsidiaries of Valhi, and pursuant to Delaware law, Valhi treats the shares of Valhi common stock that we 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 us, Kronos Worldwide, 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 common stock, except to the extent of her pecuniary interest in such shares, if any. The Family Trust (and the Trustee) disclaim beneficial ownership of all shares of our common stock, except to the extent of their 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 Valhi’s direct ownership of approximately 82.7% of the outstanding shares of our common stock, we are considered a controlled company under the listing standards of the NYSE. Pursuant to the listing standards, a controlled company may choose not to have a majority of independent directors, independent compensation, nominations or corporate governance committees or charters for these committees. While we currently have a majority of independent directors, we have chosen not to have an independent nominations or corporate governance committee or charters for these committees. Our board of directors believes that the full board of directors best represents the interests of all of our shareholders and that it is appropriate for all matters that would otherwise be considered by a nominations, corporate governance or risk oversight committee to be considered and acted upon by the full board of directors. Applying the NYSE director independence standards without any additional categorical standards, our board of directors has determined that John E. Harper, Kevin B. Kramer, Meredith W. Mendes, Cecil H. Moore, Jr. and R. Gerald Turner are independent and have no material relationship with us other than serving as our directors. While the members of our management development and compensation committee currently satisfy the independence requirements of the NYSE, we have chosen not to satisfy all of the NYSE corporate governance standards for a compensation committee, including not having a charter for our management development and compensation committee.

2025 Meetings and Standing Committees of the Board of Directors. The board of directors held four meetings in 2025. Each of our incumbent directors attended all 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 2025. It is expected that each director nominee will attend our 2026 annual meeting of shareholders, which is held immediately before the annual meeting of the board of directors. All of our directors who were elected at our 2025 annual shareholder 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 shareholder 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 corporate governance standards (without additional categorical standards) and SEC regulations, as applicable, the board of directors has determined that:

No member of our audit committee serves on more than three public company audit committees. For further information on the role of our audit committee, see the Audit Committee Report in this proxy statement. The current members of our audit committee are Cecil H. Moore, Jr. (chairman), John E. Harper, Kevin B. Kramer, Meredith W. Mendes and R. Gerald Turner. Our audit committee held seven meetings in 2025.

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

Table of Contents

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 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 New Jersey law on what duties directors may delegate. The management development and compensation committee has delegated to a committee of our officers the authority to oversee the administration of the benefit plans sponsored by us for our retirees and their dependents. 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 Cecil H. Moore, Jr. (chairman), John E. Harper and Meredith W. Mendes. Our management development and compensation committee held one meeting and took action by written consent on one occasion in 2025.

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 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:

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 possess a diverse range of senior

Table of Contents

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 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 Courtney J. Riley serves on our board. The board of directors believes our current leadership structure is appropriate for a controlled company under the NYSE corporate governance guidelines. 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 shareholder value for all of our shareholders. 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.

Pursuant to our corporate governance guidelines, our non-management directors (who are not executive officers of NL) 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 2025, we complied with the NYSE requirements for meetings of our independent and non-management directors.

Shareholder Proposals and Director Nominations for the 2027 Annual Meeting of Shareholders. Under the rules of the SEC, in order to be considered for inclusion in next year’s proxy statement, a shareholder proposal must be received by us no later than [ • ], 2026. The notice should be in writing and must comply with the proxy rules of the SEC. If the date of our 2027 annual shareholders meeting changes by more than 30 days from May 14, 2027 (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 shareholder proposal or director nomination to be presented from the floor of our 2027 annual meeting must be received by our corporate secretary not later than the 120th day nor earlier than the 150th day prior to May 14, 2027 (the first anniversary of this year’s annual meeting). If the date of our 2027 annual meeting is more than 30 days before or after May 14, 2027, shareholder proposals must be delivered no later than the 10th day following the date that notice of the date of our annual meeting is mailed or the public disclosure of the date for such annual meeting, whichever is earlier. Any shareholder proposal must be, under law, an appropriate subject for shareholder action to be brought before the meeting. In addition, in order to present a shareholder proposal or nominate a director at our 2027 annual meeting, the shareholder must satisfy certain other requirements, including information requirements, set forth in our amended and restated bylaws. Shareholder proposals and director nominations should be directed to NL Industries, 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, shareholders who intend to solicit proxies in support of director nominees other than NL’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 14, 2027) and comply with the other requirements of that rule.

Communications with Directors. Shareholders 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 NL Industries, 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

Table of Contents

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 2025, Cecil H. Moore, Jr., John E. Harper and Meredith W. Mendes served on our management development and compensation committee. No such member of the committee:

For 2025, no executive officer of ours had any interlock relationships within the scope of the intent of applicable SEC rules. However, during 2025 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. We intend to disclose changes to or waivers from the code by posting to our website at www.nl-ind.com (under the company-corporate governance section) if disclosure is required by SEC or NYSE 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.nl-ind.com under the company-corporate governance section.

Insider Trading Policy. We have adopted an insider trading policy governing the purchase, sale, and other transactions involving our securities by our directors, officers and employees. A copy of our insider trading policy is filed as Exhibit 19.1 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. In addition, with regard to NL’s trading in its own securities, it is our policy to comply with the federal securities laws and the applicable exchange listing requirements.

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 each of the last three years, all of our named executive officers were employed by Contran and provided their services to us pursuant

Table of Contents

to our ISA with Contran. Such individuals also provided services to CompX and Kronos Worldwide under Contran’s ISAs with those companies.

​

As defined in the Glossary of Terms at the beginning of this proxy statement, the phrase “named executive officers” refers to the five persons whose compensation is summarized in the 2025 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 Shareholder Vote on Executive Officer Compensation. For the 2025 annual meeting of shareholders, we submitted a nonbinding advisory proposal recommending the shareholders adopt a resolution approving the compensation of our named executive officers as disclosed in the 2025 proxy statement. At the annual meeting, the resolution received the affirmative vote of 87.0% of the shares of our common stock eligible to vote at the annual meeting. We considered the favorable result and determined not to make any material changes to our compensation practices.

Intercorporate Services Agreements. We pay Contran a fee for services provided by Contran to us 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, all of which as noted above were employed by Contran, and as a result a portion of the aggregate ISA fee we paid to Contran was paid for services provided to us by our named executive officers. The nature of the duties of each of our named executive officers who are employees of Contran are consistent with the duties normally associated with the officer titles and positions such officer holds with us. Pursuant to Contran’s ISAs with CompX and Kronos Worldwide, those companies also paid a fee to Contran for, among other things, the services our named executive officers provided to those companies, which fees were approved by the independent directors of those companies.

The charges under these ISAs reimburse 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 these ISAs 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 2025 under these ISAs. Under the various ISAs among Contran and its subsidiaries and affiliates, we share the cost of the employment of our named executive officers with Contran and certain of its other publicly and privately held subsidiaries. For our named executive officers, the portion of the annual charge we paid for each of the last three years to Contran under these ISAs attributable to each of their services is set forth in the 2025 Summary Compensation Table in this proxy statement. As discussed further below, the amounts charged under the ISAs are dependent upon Contran’s cost of employing or engaging the personnel who provide the services to us (including the services of our named executive officers) 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 ISAs 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 named executive officers, estimates the percentage of time that each Contran employee, including 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 and affiliates 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 2025 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 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, 2025.

​

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 (plus any other amounts required by tax regulations) is 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. However, Contran has agreed to absorb the impact of any such income tax deduction disallowance resulting from such totals in excess of $1.0 million. In each of 2023, 2024 and 2025, the $1.0 million limit was exceeded by NL for certain individuals, and it may be exceeded in 2026.

No Director Fees or Equity-Based Compensation for Executives.  Our executive officers, including our named executive officers, are not eligible to receive cash compensation or equity-based compensation for their service on the board of directors of us, CompX or Kronos Worldwide. For the years reflected in the 2025 Summary Compensation Table, we did not pay Mr. Simmons any compensation for his service as a director of us, CompX or Kronos Worldwide and did not pay Ms. Riley for her services as one of our directors.

​

Prior to 2023, 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 2026, 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 that our compensation discussion and analysis be included in this proxy statement.

Our management development and compensation committee submits the foregoing report as of February 26, 2026.

Summary of Cash and Certain Other Compensation of Executive Officers. The 2025 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, 2025. All of our named executive officers were employees of Contran and provided their services to us and our subsidiaries pursuant to our ISA with Contran for each year in which they are included in the 2025 Summary Compensation Table. For a discussion of this ISA, see the Intercorporate Services Agreements part of the Certain Relationships and Transactions section of this proxy statement.

2025 Summary Compensation Table (1)

Table of Contents

​

No Grants of Plan-Based Awards. During 2025, no named executive officer received any plan-based awards from us or our subsidiaries.

No Outstanding Equity Awards at December 31, 2025. At December 31, 2025, none of our named executive officers held outstanding stock options to purchase shares of our common stock (or common stock of our parent or subsidiary companies or Kronos Worldwide or its subsidiaries) or held any equity incentive awards for such shares. We do not have policies or practices on the timing of awards of options in relation to the disclosure of material nonpublic information because we do not award options.

No Option Exercises or Stock Vested. During 2025, 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 2025, the total annual compensation (as disclosed in the 2025 Summary Compensation Table) of Courtney J. Riley, our chief executive officer, is $1,412,000; the reasonable estimate of the median of the annual total compensation of all of our employees except our

Table of Contents

chief executive officer, calculated in a manner consistent with Item 402(u) of Regulation S-K, is $81,209; and the ratio of such two amounts is 17 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 worldwide 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 the random sample as reflected in our payroll records, the median employee was estimated by determining the employee in the 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. There has been no change in our employee population or employee compensation arrangements since that median employee was identified that we believe would significantly impact our pay ratio disclosure, except that the median employee that we identified in October 2023 left the company during 2024. As permitted by SEC rules we identified a new median employee, whose compensation is substantially similar to the original median employee based on the compensation measure used to select the original median employee.

Director Compensation. Our directors who are not employees of Contran or one of its subsidiaries or affiliates are eligible for cash compensation for their service as one of our directors. The table below reflects the annual rates of their retainers for 2025.

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 shareholder meetings, each of our eligible directors elected on that day receives a grant of shares of our common stock 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.

The following table provides information with respect to compensation each of our eligible directors earned for their 2025 director services provided to us.
