Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Geospace Technologies Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Geospace Technologies Corporation and its subsidiaries (the Company) as of September 30, 2023 and 2022, the related consolidated statements of operations, comprehensive income, 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 September 30, 2023 and 2022, 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 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 Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate 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 matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Inventory Valuation

As described in Note 1 to the consolidated financial statements, the Company’s consolidated inventories balance, which is stated at lower of cost or net realizable value, was $43.3 million as of September 30, 2023. The valuation of inventories is based on the Company’s periodic review of the composition of its inventories to determine if market demand, product modifications, technology changes, excessive quantities on-hand and other factors hinder its ability to recover its investment in such inventories. The Company’s assessment is based upon historical product demand, estimated future product demand and various other judgments and estimates. Inventory obsolescence reserves are recorded when such assessments reveal that portions or components of the Company’s investment will not be realized in its operating activities.

We identified the valuation of inventories at the lower of cost or net realizable value as a critical audit matter due to the significant judgment and estimates required by management. Determining whether a decline in value has occurred requires management to make complex judgments related to (i) historical and estimated future product demand in relation to quantities on hand and (ii) obsolescence of certain products based on changes in technology and demand. Auditing these judgments is especially challenging and involved significant auditor judgment due to fluctuations in sales trends and evolving customer demands.

Our audit procedures related to the Company’s valuation of inventory included the following, among others:

● We evaluated management’s calculation of the inventory valuation reserve by testing the mathematical accuracy of the calculation.

● We tested the completeness, accuracy, and relevance of the reports and inputs used in the Company’s analysis.

● We evaluated the appropriateness and consistency of management’s methods and assumptions used in developing their estimate of the inventory valuation reserve, which included consideration of recent changes in historical usage information.

● We evaluated management’s process for subsequent adjustments to net realizable value by performing a retrospective review on an individual item basis to test for subsequent changes in the inventory values after the net realizable value had been established.

● We compared actual purchases and sales data on an individual item basis for all inventory items and aggregated to perform an independent assessment of the net realizable value of inventory.

Valuation of Long-lived Assets for impairment – Emerging Markets Asset Group

As discussed in Note 10 to the consolidated financial statements, the Company assessed $3.3 million of long-lived assets associated with its Emerging Markets asset group for recoverability. As part of their quantitative assessment, the Company performed a recoverability assessment in which its carrying value was compared to estimated undiscounted cash flows over the remaining useful life of the asset group’s primary asset, its developed technology. Key assumptions in the analyses include revenue projections, including the probability of obtaining new contracts, and cash flow projections. Estimated future cash flows of the Company’s Emerging Markets asset group include the Company’s ability to obtain an additional contract with its significant customer.

We identified the valuation of long-lived assets for the Emerging Market’s asset group as a critical audit matter because of the significant assumptions management makes in determining the estimate, including revenue and cash flow projections. Auditing management’s assumptions of revenue and cash flow projections involved a high degree of auditor judgment and increased audit effort, and changes in these assumptions could have a significant impact on the fair value of the Emerging Market’s asset group and potential impairment charges.

Our audit procedures related to the Company’s valuation of long-lived assets for the Emerging Markets asset group included the following, among others:

● We evaluated the reasonableness of management’s revenue and cash flow projections by comparing to historical results, inquiry of management of the asset group regarding additional contracts with its significant customer, review of publicly available industry information, and testing the completeness and accuracy of the data used in the projections.
