**ADDITIONAL INFORMATION REGARDING THE BOARD OF DIRECTORS**

#### Status as a Controlled Company
Because Messrs. Dan Wilks and Farris Wilks, entities owned by or affiliated with them and certain individuals related to or affiliated with such persons or entities (collectively, the "Wilks Parties") beneficially own 24,659,095 shares of our Common Stock, representing approximately 79% of the voting power of the Company as of April 21, 2026, we are a controlled company under the Sarbanes-Oxley Act of 2002 ("Sarbanes-Oxley") and rules of The Nasdaq Stock Market ("Nasdaq"). Additionally, the Wilks Parties are currently, and we expect that they will continue to be, deemed a group for purposes of certain rules and regulations of the SEC. Under the Nasdaq rules, a company of which more than 50% of the voting power is held by another person or group of persons acting together is a controlled company and may elect not to comply with certain Nasdaq corporate governance requirements, including the requirements that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a majority of the board of directors consist of independent directors as defined under the rules of Nasdaq;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• director nominees be selected or recommended for the board's selection by independent directors constituting a majority of the board's independent directors or by a nominating committee composed entirely of independent directors, with a written charter or board resolution, as applicable, addressing the committee's purpose and responsibilities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the compensation committee be composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities.

**Discussions with Controlling Stockholder**

We have been in discussion with our controlling shareholder, Wilks Brothers, LLC ("Wilks Brothers"), and certain of its affiliates with respect to one or more transactions involving assets owned by Wilks Brothers and/or certain of its affiliates, which may include, among other things, asset contributions or sales, a business combination transaction or other similar transactions.

There is no guarantee that we will enter into a definitive agreement with any such parties regarding any such transaction. The terms of any potential agreement between us and Wilks Brothers, and/or any of its affiliates, would be contingent on certain conditions, including completion of due diligence and the negotiation of definitive transaction documents. Our Board of Directors has formed a special committee of independent directors (the "Special Committee"), which has retained independent legal and financial advisors, to evaluate, negotiate and make recommendations to the Board regarding any such transaction with Wilks Brothers and/or its affiliates, including whether to pursue or decline to pursue any proposed transaction.

[**Table of Contents**](#TOC)

#### Director Independence
Our Board of Directors has determined that Messrs. Bradley, Conly and Fernandes qualify as "independent" in accordance with the published listing requirements of Nasdaq and that each of the members of the Audit Committee, Compensation Committee and Nominating Committee, as applicable, qualify as "independent" in accordance with Nasdaq requirements. The Nasdaq independence definition includes a series of objective tests, such as that the director is not an employee of the company and has not engaged in various types of business dealings with the company. In addition, as further required by the Nasdaq rules, our Board of Directors has made a subjective determination as to each independent director that no relationships exist that, in the opinion of the Board of Directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

In addition, each of the members of the Audit Committee and Compensation Committee of our Board of Directors qualify as "independent" under additional standards established by the Securities and Exchange Commission ("SEC") for members of such committees. The Audit Committee includes at least one member who is determined by our Board of Directors to meet the qualifications of an "audit committee financial expert" in accordance with SEC rules, including that the person meets the relevant definition of an "independent" director. Mr. Conly has been determined to be an audit committee financial expert, which was determined based on our Board of Director's qualitative assessment of Mr. Conly's level of knowledge, experience and formal education. The designation does not impose on Mr. Conly any duties, obligations or liabilities that are greater than those that are generally imposed on him as a member of the Audit Committee and the Board of Directors, and Mr. Conly's designation as an audit committee financial expert pursuant to this SEC requirement does not affect the duties, obligations or liabilities of any other member of the Audit Committee or the Board of Directors.

**Meetings and Committees of Directors**

During 2025, the Board of Directors held five meetings, the Audit Committee held five meetings, the Compensation Committee held two meetings, and the Nominating Committee held no meetings. Each of the directors attended all of the meetings of the Board of Directors and all of the committees on which they served during 2025.

*Audit Committee. The Audit Committee is a standing committee of the Board of Directors. The functions of the Audit Committee are to determine whether our management has established internal controls which are sound, adequate and working effectively; to ascertain whether our assets are verified and safeguarded; to review and approve external audits; to select, engage and supervise our independent public accountants; and to determine and approve the fees paid to the independent public accountants. The members of the Audit Committee are Messrs. Bradley, Conly (Chair) and Fernandes.* 

The Audit Committee operates under a written charter adopted by the Board of Directors. The Audit Committee Charter is reviewed annually, and is posted on our website at www.dawson3d.com in the "Corporate Governance" area of the "Investor Relations" section.

*Compensation Committee. The Compensation Committee is a standing committee of the Board of Directors. The primary function of the Compensation Committee is to determine that compensation for our executive officers is competitive and enables the Company to motivate and retain the talent needed to lead and grow our business. The members of the Compensation Committee are Messrs. Bradley (Chair) and Conly.* 

The Compensation Committee operates under a written charter adopted by the Board of Directors. The charter is reviewed annually and is posted on our website at www.dawson3d.com in the "Corporate Governance" area of the "Investor Relations" section.

*Nominating Committee. The Nominating Committee is a standing committee of the Board of Directors. The primary function of the Nominating Committee is to determine the slate of director nominees for election to our Board of Directors. The Nominating Committee considers candidates recommended by our shareholders, directors, officers and outside sources, and considers each nominee's personal and professional integrity, experience, skills, ability, and willingness to devote the time and effort necessary to be an effective board member with the commitment to acting in the best interests of the Company and our shareholders. While the Company has no formal diversity policy, the Nominating Committee gives consideration to having an appropriate mix and diversity of backgrounds, skills and professional experiences on our Board of Directors, the qualifications that the Committee believes must be met by prospective nominees, qualities or skills that the Committee believes are necessary for one or more of our directors to possess, and standards for the overall structure and composition of our Board of Directors. The same criteria would be evaluated with respect to candidates recommended by shareholders. The members of the Nominating Committee are Messrs. Wilks and Krylov (Chair). In reliance on exemptions permitted for a controlled company under Nasdaq rules, the Nominating Committee is not composed of independent directors (as defined under Nasdaq rules).*

[**Table of Contents**](#TOC)

The Nominating Committee operates under a written charter adopted by the Board of Directors. The charter is reviewed annually and is posted on our website at www.dawson3d.com in the "Corporate Governance" area of the "Investor Relations" section.

**Director Qualifications**

Because the identification, evaluation and selection of qualified directors is a complex and subjective process that requires consideration of many intangible factors, and will be significantly influenced by the particular needs of our Board from time to time, our Board has not adopted a specific set of minimum qualifications, qualities or skills that are necessary for a nominee to possess, other than those that are necessary to meet U.S. legal, regulatory and Nasdaq listing requirements and the provisions of our Amended and Restated Certificate of Formation and Amended and Restated Bylaws (the "Bylaws"), and the charters of the committees of our Board. When considering nominees, our Board may take into consideration many factors including, among other things, a candidate's experience in corporate management, professional and academic experience relevant to the Company's industry and strategic plan, diversity, skills, financial and other expertise, breadth of experience, knowledge about our business or industry and ability to devote adequate time and effort to responsibilities of our Board in the context of its existing composition. In general, persons recommended by shareholders will be considered on the same basis as candidates from other sources. If a shareholder wishes to recommend a candidate for election as a director at the 2027 Annual Meeting of Shareholders, it must follow the procedures described in "*Shareholders Nominations to our Board of Directors*" below.

**Board of Directors' Role in Risk Oversight**

The Board of Directors is generally responsible for risk oversight. Management has implemented internal processes to identify and evaluate the risks inherent in the Company's business and to assess the mitigation of those risks. Our Board of Directors' leadership structure, including the Audit Committee's responsibility to oversee any significant financial risk exposures and our practice of a high degree of interaction between our directors and members of senior management, facilitates and provides this oversight function. Management reports either to the Audit Committee or the full Board of Directors, depending on the type of risk involved, regarding the identified risks and the mitigation strategies planned or in place to address such risks.

**Stockholder Nominations to our Board of Directors**

In accordance with our Bylaws, shareholders who wish to have their nominees for election to the Board of Directors considered by the Nominating Committee must submit such nomination to our Secretary for receipt not less than 60 days nor more than 90 days prior to the anniversary date of the date on which the Company first mailed its proxy materials for the preceding annual meeting of shareholders. Pursuant to our Bylaws, the notice of nomination is required to contain certain information about both the nominee and the shareholder making the nomination, including information sufficient to allow the independent directors to determine if the candidate meets the criteria for Board of Director membership. A nomination that does not comply with the above procedure will be disregarded.

**Code of Business Conduct and Ethics**

The Company has adopted a Code of Business Conduct and Ethics that represents both the code of ethics for the principal executive officer, principal financial officer, and principal accounting officer, as required pursuant to Rule 406 of Regulation S-K, and the code of business conduct and ethics for directors, officers and employees under Nasdaq listing standards. Every director, officer and employee of the Company must conduct himself or herself according to the Code of Business Conduct and Ethics, which is available on the Company's website at www.dawson3d.com.

**11. *EXECUTIVE COMPENSATION***

**Director Compensation**

We have adopted a comprehensive director compensation program in order to attract and retain qualified non-employee directors who are essential to our future success, growth, and governance. For services performed in 2025, each non-employee director received fees consisting of annualized compensation of $125,000 representing quarterly cash payments of approximately $31,250. Members of the Audit Committee received additional annualized compensation of $18,000, with the Chairman receiving $24,000, representing quarterly cash payments of approximately $4,500 and $6,000, respectively. Members of the Compensation Committee received additional annualized compensation of $6,000 representing quarterly cash payments of $1,500. We also reimburse reasonable expenses incurred by our directors in attending meetings and other company business. None of the reimbursements for our non-employee directors exceeded

**Potential Payments Upon a Change of Control or Termination**

Award agreements under the amended and restated Dawson Geophysical Company 2016 Stock and Performance Incentive Plan (the "Restated 2016 Plan") generally permit accelerated vesting of awards in the event of a change of control or upon termination of employment for reasons other than cause, or termination of employment due to death or disability.

*Payment Upon Termination by the Company Without Cause or by the Executive for Good Reason*

If there is a termination of Mr. Clark's employment by the Company without "cause" or by Mr. Clark for "good reason" (as those terms are defined in the Clark Employment Agreement), Mr. Clark will be entitled to receive, subject to his execution and nonrevocation of a general release of claims: (i) severance payments in an amount equal to his then-current base salary for the remainder of the then-applicable term of his employment (as described below), (ii) a lump sum payment of any earned but unpaid performance bonus for the calendar year or fiscal year, as applicable, ending immediately prior to such termination, (iii) a lump sum payment equal to the cost to Mr. Clark to extend his then-current group health plan benefits for 18 months following the date of termination (the "Clark COBRA Benefit"), and (iv) if such termination occurs more than four months into the year, a lump sum payment equal to the performance bonus, if any, that Mr. Clark would have earned for the calendar year or fiscal year, as applicable, during which such termination occurs, based on the Company's achievement of applicable performance metrics, prorated to reflect the portion of such year during which Mr. Clark was employed by the Company (the "Clark Prorated Bonus"). Additionally, Mr. Clark's "covered awards" (as defined in the Clark Employment Agreement) shall become automatically fully vested and exercisable, as the case may be, but only to the extent such acceleration would not result in the imposition of an applicable tax under Section 409A of the Code.

If there is a termination of Mr. Mays' employment by the Company without "cause" or by Mr. Mays for "good reason" (as those terms are defined in the Mays Employment Agreement), Mr. Mays will be entitled to receive, subject to his execution and nonrevocation of a general release of claims: (i) severance payments in an amount equal to his then-current base salary, (ii) a lump sum payment of any earned but unpaid performance bonus for the calendar year or fiscal year, as applicable, ending immediately prior to such termination, (iii) a lump sum payment equal to the cost to Mr. Mays to extend his then-current group health plan benefits for 18 months following the date of termination (the "Mays COBRA Benefit"), and (iv) if such termination occurs more than four months into the year, a lump sum payment equal to the performance bonus, if any, that Mr. Mays would have earned for the calendar year or fiscal year, as applicable, during which such termination occurs, based on the Company's achievement of applicable performance metrics, prorated to reflect the portion of such year during which Mr. Mays was employed by the Company (the "Mays Prorated Bonus").

[**Table of Contents**](#TOC)

*Payment Upon Termination Following a Change of Control*

The Restated 2016 Plan defines a "change of control" as, except as otherwise reflected in an award agreement, occurring when (i) any "person" (as such term is used in Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) is or becomes a beneficial owner, directly or indirectly, of securities of the Company representing 20% or more of the total voting power of the Company's then outstanding securities; (ii) the individuals who were members of the Board of Directors of the Company immediately prior to a meeting of the shareholders of the Company involving a contest for the election of directors shall not constitute a majority of the Board of Directors following such election unless a majority of the new members of the Board were recommended or approved by majority vote of members of the Board of Directors immediately prior to such shareholders' meeting; (iii) the Company shall have merged into or consolidated with another corporation, or merged another corporation into the Company, on a basis whereby less than 50% of the total voting power of the surviving corporation is represented by shares held by former shareholders of the Company prior to such merger or consolidation; or (iv) the Company shall have sold, transferred or exchanged all, or substantially all, of its assets to another corporation or other entity or person. The change of control definition under Section 409A of the Internal Revenue Code will apply to the extent necessary to comply with the requirements of Section 409A of the Internal Revenue Code in the event an award under the Restated 2016 Plan is subject to Section 409A of the Internal Revenue Code. The definition of "change of control" under the Employment Agreements is defined in a manner consistent with the Restated 2016 Plan.

Mr. Clark and Mr. Mays are the only employees of the Company with change in control protections in their employment agreements. See below for specific obligations of the Company with respect to their employment agreements.

If, in the 12-month period immediately following a "change in control" of the Company, there is a termination of Mr. Clark's employment by the Company without "cause" or by Mr. Clark for "good reason" (as those terms are defined in the Clark Employment Agreement), Mr. Clark will be entitled to receive an amount equal to 2x his then-current base salary that would have been payable to Mr. Clark had he remained employed by the Company for the applicable period, 2x the Clark COBRA Benefit and 2x the Clark Prorated Bonus. Additionally, Mr. Clark's "covered awards" (as defined in the Clark Employment Agreement) shall become automatically fully vested and exercisable, as the case may be, but only to the extent such acceleration would not result in the imposition of an applicable tax under Section 409A of the Code.

The Clark Employment Agreement has a 2-year term commencing June 16, 2023 (the effective date of Mr. Clark's original employment agreement with the Company), with automatic annual renewal thereafter on each anniversary of such date, unless notice of non-renewal is provided at least 60 days prior to such anniversary (and subject to earlier termination in accordance with the terms of the agreement). The Clark Employment Agreement includes certain restrictive covenants that apply during, and for specified periods after, Mr. Clark's employment, including with respect to confidentiality, non-disparagement, non-solicitation, and intellectual property assignment.

If, in the 12-month period immediately following a "change in control" of the Company, there is a termination of Mr. Mays' employment by the Company without "cause" or by Mr. Mays for "good reason", Mr. Mays will be entitled to receive an amount equal to 2x his then-current base salary, 2x the Mays COBRA Benefit and 2x the Mays Prorated Bonus.

The Mays Employment Agreement has a 2-year term commencing November 20, 2023, with automatic annual renewals thereafter at the end of such term, unless notice of non-renewal is provided at least 60 days prior to the end of the then-applicable term (and subject to earlier termination in accordance with the terms of the agreement). The agreement includes certain restrictive covenants that apply during, and for specified periods after, Mr. Mays' employment, including with respect to confidentiality, non-disparagement, non-solicitation, and intellectual property assignment.

**Insider Trading and Short-Selling, Hedging and Pledging Prohibitions**

We have adopted insider trading policies and procedures governing the purchase, sale and other transactions in Company securities by the Company's directors, officers, and employees, and other covered persons, that we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations and applicable exchange listing standards. We do not permit our directors or executive officers to speculate in our common stock which includes, without limitation, "short-selling" and/or buying publicly traded options. We also do not permit our directors or executive officers to enter into hedging transactions with respect to their ownership of our common stock or to pledge any of our common stock.

[**Table of Contents**](#TOC)

**Timing of Equity Grants**

All equity grants made to executive officers must be approved by the Compensation Committee. The Compensation Committee does not currently take material non-public information into account when determining the timing of equity grants, and the Company does not time nor does it plan to time the release of material, non-public information for the purpose of affecting the value of employee or Board compensation. During fiscal year 2025 and 2024, the Company did not grant stock options (or similar awards) to any NEO during any period beginning four business days before and ending one day after the filing of any Company periodic report on Form 10-Q or Form 10-K, or the filing or furnishing of any Company Form 8-K that disclosed any material non-public information.

Pursuant to the Indemnification Agreements, we agreed to indemnify each Indemnitee to the fullest extent permitted by applicable law against any and all expenses arising from any Proceeding (as defined in the Indemnification Agreements) in which an Indemnitee was, is or will be involved as a party or otherwise by reason of any Indemnitee's service as, or actions taken while (i) a director or officer of the Company or (ii) at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. Following a request by an Indemnitee, we are required to advance (within five days of receipt of such request) to such Indemnitee any and all expenses relating to the Indemnitee's defense of such Proceeding, subject to the Indemnitee's compliance with certain provisions of the Texas Business Organizations Code ("TBOC").

Our obligation to provide indemnification under the Indemnification Agreements is subject to a determination in accordance with Section 8.103(a)(1) or (2) of the TBOC.

We are not required to indemnify an Indemnitee to the extent such indemnification conflicts with Texas law.
