**(c) Address of Issuer's Principal Executive Offices:**
508 West Wall, Suite 800, Midland, TX, 79701

This Amendment No. 6 (this "Amendment") amends and supplements the Schedule 13D originally filed by Dan Wilks, Staci Wilks, Wilks Brothers, LLC ("Wilks") and Farris Wilks with the Securities and Exchange Commission (the "SEC") on January 19, 2021, as amended by Amendment No. 1 thereto filed on October 25, 2021, Amendment No. 2 thereto filed on January 14, 2022, Amendment No. 3 thereto filed on January 28, 2022, Amendment No. 4 thereto filed on June 26, 2023, and Amendment No. 5 thereto filed on October 30, 2023  (collectively, the "Schedule 13D"), relating to shares of common stock, par value $0.01 per share ("Common Stock"), of Dawson Geophysical Company (the "Issuer"). Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.

**Item 4. Purpose of Transaction**

The Reporting Persons have had and intend to continue to engage in discussions with the Issuer with respect to one or more transactions involving assets owned by the Reporting Persons and/or certain of their affiliates, which may include, among other things, asset sales, a business combination transaction or other similar transactions.  There is no guarantee that the Reporting Persons (or their applicable affiliates) and the Issuer will enter into a definitive agreement regarding any such a transaction, nor is there certainty as to the form or structure that any such transaction may take. 

The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer's financial position and investment strategy, the price levels of the shares of Common Stock, conditions in the securities markets and general economic and industry conditions, the Reporting Persons intend to continue to consider, explore and/or develop plans and may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with the Issuer's management and the Board, engaging in discussions with shareholders of the Issuer and others about the Issuer and the Reporting Persons' investment, making proposals to the Issuer concerning strategic transactions, including business combinations, a sale of the Issuer as a whole or in parts or acquisitions or investments by the Issuer, changes to the capital allocation strategy, capitalization, ownership structure, Board structure (including Board composition), operations of the Issuer, purchasing additional shares of Common Stock, selling some or all of their shares of Common Stock, engaging in short selling of or any hedging or similar transaction with respect to the shares of Common Stock, or take any other actions with respect to their investment in the Issuer permitted by law, including any or all of the actions set forth in paragraphs (a)-(j) of Item 4 of Schedule 13D.

**Item 5. Interest in Securities of the Issuer**

**(a)**
Each Reporting Person's beneficial ownership of the Common Stock and percentage ownership as of the date of this Amendment is reflected on that Reporting Person's cover page, which is incorporated herein by reference.  The percent of class stated therein for each Reporting Person is based on the 31,047,801 shares of Common Stock of Issuer issued and outstanding as of August 11, 2025, as reported in the Issuer's Quarterly Report filed with the SEC on August 13, 2025.

Wilks beneficially owns 24,658,746 shares of Common Stock, representing 79.42% of the issued and outstanding Common Stock, consisting of (i) 9,111,736 shares of Common Stock directly owned by Wilks and (ii) 15,547,010 shares of Common Stock directly owned by WB Acquisitions Inc. ("WBA"), which is a subsidiary of Wilks. If Wilks and WBA were deemed to be a group with Staci Wilks, such group would beneficially own 24,659,095 shares of Common Stock. Wilks is a manager-managed limited liability company, managed by Dan Wilks and Farris Wilks. Dan Wilks and Farris Wilks are brothers and may be deemed to indirectly beneficially own the shares of Common Stock directly beneficially owned by each of Wilks and WBA.

**(b)**
Items 7 through 10 of the cover pages of this Schedule 13D for each of the Reporting Persons are incorporated herein by reference.

**(c)**
Not applicable.
