Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors of

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of SANUWAVE Health, Inc. (the “Company”) and Subsidiaries as of December 31, 2024 and 2023, the related consolidated statements of comprehensive loss, stockholders’ deficit, and cash flows for each of the two years in the period ended December 31, 2024, and the related notes (collectively referred to as 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 each of the two years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

Explanatory Paragraph – Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 2, the Company has incurred recurring losses, has negative working capital, and needs to refinance its debt to meet its obligations and sustain its operations. These conditions raise substantial doubt about the Company's ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

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 audits 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 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.

Valuation of Financial Instruments (Warrant Liability)

Critical Audit Matter Description

As described in Note 13 to the consolidated financial statements, the Company has entered into warrant agreements accounted for as a liability and recorded at fair value. The fair value of the warrant liability was valued using valuation techniques and key inputs as described in the footnotes.

The principal considerations for our determination that the valuation of the warrant liability is a critical audit matter were the significant judgments made by management in determining the fair value of the warrant liability. This in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions. The audit also involved the use of professionals with specialized skill and knowledge.

How the Critical Audit Matter was Addressed in the Audit

Our audit procedures related to the valuation of the financial instruments included the following, among others:

▪We obtained an understanding of the design of the Company's controls over valuation of financial instruments, including controls over management's review of the valuation models, and the significant assumptions used in determining the fair value of the financial instruments.

▪With assistance of our valuation specialists, we audited the fair value of the warrant liability, valuation methodology, and key assumptions used in determining the fair value of the warrant liability by:

a. Evaluating the appropriateness of the valuation models and techniques used in determining the fair value;

b. Assessing the reasonableness of the significant valuation inputs, including the probability weighted expected value considering the merger agreement with SEPA Acquisition Corp. (“SEPA”), the risk adjusted expected exchange ratio, the value of SEPA’s Class A common stock, the expected timing of the closing of the merger, and the probability of the merger closing;

c. Assessing the reasonableness of the significant valuation inputs, including the probability weighted expected value considering the reverse stock split of the Company’s common stock (the “Reverse Stock Split”), the expected exchange ratio, the value of the Company’s common stock, the expected timing of the effectuating of the Reverse Stock Split, and the probability of the Reverse Stock Split occurring;

d. Assessing that the significant valuation assumption inputs in the Black Scholes valuation model of the implied volatility are consistent with those that would be used by market participants through the testing of source information; and

e. Checking the mathematical accuracy of the calculation, developing independent estimates, and comparing to those selected by management, where applicable, and recalculating management’s fair value, verifying it was reasonable.

▪We audited the completeness and accuracy of the underlying data supporting the significant valuation assumption inputs.
