PROXY STATEMENT

​

​

GENERAL INFORMATION

​

We are providing this proxy statement in connection with the solicitation of proxies by and on behalf of our board of directors for use at our 2024 annual meeting of shareholders to be held on Thursday, May 16, 2024, and at any adjournment or postponement of the meeting. We are furnishing our proxy materials to holders of our common stock as of the close of business on March 19, 2024. We will begin distributing a notice of internet availability of our proxy materials to the holders of our common stock on or about April 3, 2024. Our proxy materials include:

We are not incorporating the 2023 annual report into this proxy statement and you should not consider the annual report as proxy solicitation material. The accompanying notice of annual meeting of shareholders sets forth the time, place and purposes of the meeting. 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

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

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) 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 2024 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, 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 proposal 2, 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.

Table of Contents

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

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 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. 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.

Ownership of Related Companies. Some of our directors and executive officers own equity securities of certain companies related to us.

Ownership of Kronos Worldwide and Valhi. The following table and footnotes set forth the beneficial ownership, as of the record date, of the shares of Kronos Worldwide and Valhi common stock held by each of our current directors, each of the named executive officers, and all of our current directors and executive officers as a group.

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 and Cecil H. Moore, Jr. 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.

2023 Meetings and Standing Committees of the Board of Directors. The board of directors held four meetings in 2023. 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 2023. It is expected that each director nominee will attend our 2024 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 2023 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 and Meredith W. Mendes. Our former director Thomas P. Stafford was a member of our audit committee until his death in March 2024.

Table of Contents

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 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. and (since February 2024) John E. Harper. Our former director Thomas P. Stafford was a member and chairman of our management development and compensation committee until his death in March 2024. 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 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 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 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 2023, we complied with the NYSE requirements for meetings of our independent and non-management directors.

Shareholder Proposals and Director Nominations for the 2025 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 December 3, 2024. The notice should be in writing and must comply with the proxy rules of the SEC. If the date of our 2025 annual shareholders meeting changes by more than 30 days from May 16, 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 shareholder 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 16, 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 16, 2025, shareholder 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 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 2025 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 Industries’ 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

Table of Contents

notice provisions of our bylaws (that is, in most cases no later than January 16, 2025) 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 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, Thomas P. Stafford and Cecil H. Moore, Jr. served on our management development and compensation committee. No such 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. 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.

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 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 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 Shareholder Vote on Executive Officer Compensation. For the 2023 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 2023 proxy statement. At the annual meeting, the resolution received the affirmative vote of 86.6% 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 2023 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 2023 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:

​

​

​

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 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.

​

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 2021, 2022 and 2023, the $1.0 million limit was exceeded by NL for certain individuals, and it may be exceeded in 2024.

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 2023 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 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 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 22, 2024. Thomas P. Stafford was the chairman and a member of the committee on February 22, 2024, but is not listed below due to his death in March 2024.

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 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.

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 Courtney J. Riley, our chief executive officer, is $1,399,000; 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 28 to 1.

Table of Contents

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.

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 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 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 2023 director services provided to us.

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 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% shareholders 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 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.nl-ind.com under the company-corporate governance section.

During 2023, our audit committee reviewed, adopted and ratified 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:

​

Table of Contents

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 and ratify 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. Our audit committee was also not required to approve and ratify the secured revolving credit facility with Valhi, as extended in November 2022, which provides for loans by Valhi to NLKW of up to $50 million, because such loan facility was 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 CompX, Contran, Kronos Worldwide 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.

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

Table of Contents

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 Intercorporate Services Agreements 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.

The following table sets forth the fees paid by us, our subsidiaries and Kronos Worldwide to Contran in 2023 and the amount anticipated to be paid to Contran in 2024 for services Contran provided, or will provide, us, our subsidiaries and Kronos Worldwide under the various ISAs, including the services of all of our named executive officers.
