American Shared Hospital Services, Inc.

Opinion on the Financial Statements

We have audited the accompanyingconsolidated balance sheets of American Shared Hospital Services, Inc. (the “Company”) as of December 31, 2023 and 2022, and the related consolidated statements of operations, shareholders’ equity and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2023 and 2022, and the consolidated 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 consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated 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 audits to obtain reasonable assurance about whether the consolidated 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 consolidated financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated 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 they relate.

Rental Revenue from Medical Equipment Leasing–** Estimates of Reimbursement Rates**

As described in Note 2 in the Company’s consolidated financial statements, the Company has rental revenue from medical equipment leasing on either a fee per use or revenue sharing basis that are recognized under Accounting Standards Codification 842,Leases. Under revenue sharing arrangements, the Company receives a contracted percentage of the reimbursement received by the hospital. Under fee per use arrangements, the Company receives payment from the hospital as determined by each hospital’s lease agreement with the Company.

We identified management’s estimates of reimbursement rates to record rental revenue from medical equipment leasing and related accounts receivable, as a critical audit matter. Rental revenue from medical equipment leasing and related accounts receivable involves significant judgment and estimation, including measurement uncertainty, by management based on the estimates and assumptions used and are subject to adjustments based on actual reimbursements received by the Company. In turn, auditing management’s judgments and estimates related to rental revenue from medical equipment leasing and related accounts receivable involved a high degree of subjectivity, as they are based on estimates of reimbursement rates.

The primary procedures we performed to address this critical audit matter included:
