DAWSON GEOPHYSICAL CO

To the Stockholders and Board of Directors of

Dawson Geophysical Company

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Dawson Geophysical Company and its subsidiaries (the Company) as of December 31, 2024 and 2023, the related consolidated statements of operations and comprehensive loss, stockholders’ equity and cash flows for the years then ended, and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Impairment Testing of Long-Lived Assets ​As discussed in Note 2 to the financial statements, long-lived assets are tested for impairment at the asset group level when events or changes in circumstances indicate the carrying value of the asset group may not be recoverable. Recognition of an impairment charge is required if future expected undiscounted net cash flows are insufficient to recover the carrying value of the asset group and the fair value of the asset group is below its carrying value. Depending upon the facts and circumstances, when indicators of asset impairment exist, management will test the asset group for impairment through developing a forecast of future undiscounted cash flows expected to be generated by the asset group or by estimating the fair value of assets within the asset group in lieu of detailed cash flow projections. If either the future undiscounted cash flows expected to be generated by the asset group or the fair of the assets within the asset group exceeds the carrying value of the asset group no impairment would be

recognized. During the year ended December 31, 2024, management tested two of its asset groups for impairment through estimating the fair value of certain assets within the asset groups using a market approach or cost approach, as applicable. Because the fair value of these assets collectively exceeded the carrying value of the asset groups, no impairment charges were recognized for the year ended December 31, 2024.​We identified management’s impairment testing of long-lived assets as a critical audit matter because of the significant assumptions management used in estimating the fair value of certain assets within the asset groups. Auditing management’s assumptions involved a high degree of auditor judgment and an increase in audit effort, including the use of our valuation specialists, due to the impact these assumptions could have on the accounting estimate.​Our audit procedures related to the Company’s impairment testing of long-lived assets included the following, among others:​●We tested the completeness and accuracy of the underlying data used by management by agreeing it to the underlying support.​●We utilized our valuation specialists to assist in the following procedures:oCorroborated management’s estimates through obtaining publicly available market data for certain assets within the population. oDeveloped an independent estimate of fair value for certain assets within the asset groups, utilizing publicly available market data and other information, and compared our independent estimate to the carrying value of the asset groups. ​
