Item 1.01.Entry Into Material Definitive Agreement

On October 31, 2025, Dawson Geophysical Company (the “Company”) and Dawson Operating LLC, a Texas limited liability company and a wholly owned subsidiary of the Company (“Dawson Operating” and together with the Company, the “Borrowers”), entered into a Revolving Credit Note (the “Revolving Credit Note”) in favor of Equify Financial, as lender (the “Lender”).

Pursuant to the Revolving Credit Note, the Borrowers, jointly and severally, may, from time to time until November 20, 2028, request loans from the Lender for up to an aggregate principal amount of $5,035,032. The loans outstanding under the Revolving Credit Note are payable by the Borrowers in thirty-six (36) monthly installments of principal in the amount of $139,862, together with all accrued and unpaid interest on the outstanding principal balance thereunder, commencing on December 20, 2025, and continuing thereafter until the maturity date. The interest rate applicable to loans outstanding under the Revolving Credit Note is a rate per annum equal to 13%.

The maximum borrowing limit under the Revolving Credit Note is initially $5,035,032, and such amount is reduced by $139,862 on each monthly payment date. The Borrowers may prepay up to 75% of the then outstanding principal and accrued but unpaid interest at any time without a prepayment fee.

The obligations under the Revolving Credit Note are secured by a lien on the Company’s vibrator energy source vehicles, pursuant to a Security Agreement by and between the Company and Equify, dated as of October 31, 2025.

Dan Wilks and Farris Wilks, together with certain of their affiliates, collectively hold a controlling interest in the Company and in Equify. The transaction was reviewed and approved by the Company’s Audit Committee of the Board of Directors.
