INTRODUCTION

This Amendment No. 3 (“Amendment No. 3”) amends and supplements the Tender Offer Statement on Schedule TO originally filed on November 1, 2021, as amended by Amendment No. 1 dated November 17, 2021 and Amendment No. 2 dated January 10, 2022 (as so amended, the “Schedule TO”) relating to the offer (the “Offer”) by WB Acquisitions Inc., a subsidiary of Wilks Brothers, LLC, to purchase for cash, less any applicable withholding taxes, the shares of the common stock of Dawson Geophysical Company to include disclosure related to the expiration of the Offer.

Only those items amended or supplemented are reported in this Amendment No. 3. Except as specifically provided herein, the information contained in the Schedule TO remains unchanged. You should read this Amendment No. 3 together with the Schedule TO, the Offer to Purchase, dated November 1, 2021 (the “Offer to Purchase”) and the related Letter of Transmittal, as each may be amended or supplemented from time to time. Capitalized terms used but not defined herein have the meanings ascribed to them in the Offer to Purchase.

AMENDMENTS

(a)    Items 1 through 9 and Item 11.

The Offer to Purchase and Items 1 through 9 and Item 11 of the Schedule TO, to the extent such Items incorporate by reference the information contained in the Offer to Purchase, are hereby amended and supplemented as set forth below:

The Offer expired at the end of the day on January 14, 2022 (the “Expiration Date”). American Stock Transfer & Trust Company LLC, in its capacity as depositary and paying agent for the Offer, has advised Parent and Merger Sub that a total of 15,285,001 Shares were validly tendered and not validly withdrawn (excluding Shares tendered pursuant to guaranteed delivery procedures that were not yet delivered in satisfaction of such guarantee), pursuant to the Offer as of the Expiration Date, which when combined with the 2,094,237 Shares owned by Parent and its affiliates (the “Parent Shares”), represents approximately 73.5% of the outstanding Shares. In addition, Notices of Guaranteed Delivery were delivered for 342,452 Shares, representing approximately 1.4% of the outstanding Shares, which Shares will also be purchased by Merger Sub provided such Shares are delivered in satisfaction of such guarantee.

The number of Shares validly tendered and not properly withdrawn pursuant to the Offer, when combined with the Parent Shares, satisfies the 66.67% Minimum Condition. All Conditions to the Offer having been satisfied or waived, Merger Sub irrevocably accepted for payment all such Shares validly tendered and not validly withdrawn prior to the Expiration Date. Payment of the Offer Price for such Shares will be promptly made by the Depositary in accordance with the terms of the Offer.

On January 18, 2022, Parent issued a press release announcing the final results of the Offer. A copy of such press release is filed as Exhibit (a)(5)(B) to this Amendment and is incorporated herein by reference.
