Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of NovaBay Pharmaceuticals, Inc. and subsidiaries (the “Company”) as of December 31, 2024 and 2023, and the related consolidated statements of operations, stockholders’ (deficit) equity, 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 “consolidated financial statements”). In our opinion, the consolidated 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.

Emphasis of Matter

As discussed in Note 1 to the consolidated financial statements, the Company is seeking approval from its stockholders to dissolve and distribute all remaining assets to stockholders. Management has determined that it is in the best interest of the Company and its stockholders to continue pursuing the voluntary Dissolution pursuant to the Plan of Dissolution and management’s plans regarding these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these 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 audit 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 that 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.

Allowances for Product Returns

Description of the Matter

As described in Note 2 of the consolidated financial statements, when recognizing revenue from product sales, the Company makes an estimate of the amount of consideration the Company expects to be entitled to receive. Upon recognition of these product sales, the Company records estimates for variable consideration consisting of service fees, discounts, rebates, and product returns, resulting in a reduction in product revenue. The variable consideration provisions are recorded within accrued liabilities in the same period that the related revenue is recognized. Liabilities related to the allowance for product returns involve the use of significant assumptions and judgments in their calculation. These significant assumptions and judgments include historical sales and return rates and inventory levels in the distribution channel, as well as existing return policies with customers.

The Company’s estimated allowance for product returns requires a high degree of judgment and is subject to change based on various quantitative and qualitative factors. Accordingly, extensive audit effort and a high degree of auditor judgment were needed to evaluate management’s estimates and assumptions used in the determination of the allowance for product returns. Therefore, we identified the Company’s allowance for product returns as a critical audit matter.

How We Addressed the Matter in Our Audit

We obtained an understanding of and evaluated the design of controls relating to the Company’s processes for estimating the allowance for product returns. We evaluated the significant accounting policies relating to product returns, as well as management’s application of the policies, for appropriateness and reasonableness.

We obtained the Company’s allowance for product returns analysis and performed testing procedures on the underlying data that was used in management’s development of the product returns estimate. We compared the significant assumptions used by management to customer contract information, tested the historical returns data used in the analysis, and reviewed subsequent product return activity. In addition, we performed sensitivity analyses of significant assumptions used in the analysis to determine what changes in assumptions are particularly sensitive when calculating the amount of the allowance for product returns. Additionally, we tested the mathematical accuracy of management’s calculation of revenue, net of product sales allowances, and the associated timing of revenue recognition, in the consolidated financial statements.
