DWSN · Dawson Geophysical Company

This Form 10-K/A is filed exclusively to comply with General Instruction G(3) of Form 10-K, which permits the incorporation of Part III disclosures (Items 10 through 14) by amendment when those items are not yet available at the time of the initial filing. The original 10-K was filed on March 31, 2026; this amendment, filed April 30, 2026, adds the remaining Part III content without modifying any financial statements, notes, or management discussion. Critically, the authoritative financial packet confirms that no financial metrics — raw, derived, or segmented — were submitted, validated, or retained for FY2025 in connection with this filing. As a result, there are no audited or unaudited financial statements, no income statement line items, no balance sheet positions, no cash flow reconciliations, and no footnotes supporting quantitative assertions.

Because the filing contains no financial data, it offers no basis for assessing Dawson Geophysical’s revenue generation, cost structure, profitability, liquidity, capital expenditures, or working capital trends for FY2025. There is no discussion of seismic market demand, fleet utilization, backlog, contract renewals, or competitive positioning — all material to understanding the operational reality of a land-based geophysical services provider. Similarly, no forward-looking statements, risk factor updates, or strategic initiatives are introduced here; the document is strictly backward-looking and administrative in scope.

The absence of a business context packet further constrains interpretation: no governance structure details (e.g., board composition, voting control, or related-party affiliations), no industry benchmarks, and no regulatory or contractual constraints are provided to contextualize the procedural nature of the amendment. All previously drafted numeric claims — including references to related-party expenses, audit fees, and percentage changes — were removed during audit precisely because they lack traceable support in the submitted financial packet. This reinforces that the filing’s sole function is disclosure completeness, not performance communication. Investors seeking insight into Dawson’s FY2025 financial condition or operational execution must rely entirely on the original 10-K, which remains outside the scope of this amendment and is not reproduced or referenced herein. No reconciliation, restatement, or explanatory bridge between filings is offered — consistent with the narrow purpose of a G(3) amendment.
