Emerging growth company ☐

If an emerging growth company, indicate by check mark if the registrant has elected not to use the extended transition period for complying with any new or revised financial accounting standards provided pursuant to Section 13(a) of the Exchange Act. ☐

Item 2.02 Results of Operations and Financial Condition.

On November 6, 2025, Eton Pharmaceuticals, Inc. issued a press release announcing its financial results for the third quarter ended September 30, 2025. A copy of the press release is attached hereto as Exhibit 99.1.

The information in this Item 2.02 and the attached Exhibit 99.1 are being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section. The information in this Item 2.02 and the attached exhibit shall not be incorporated by reference into any registration statement or other document pursuant to the Securities Act of 1933, as amended.

Discussion of Non-GAAP Financial Measures

In the Press Release, we present certain financial information, specifically Adjusted EBITDA, which is not in accordance with generally accepted accounting principles (“U.S. GAAP”). We present Adjusted EBITDA in the Press Release because this metric assists us in comparing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. Our management uses Adjusted EBITA:

● for planning purposes, including the preparation of our annual operating budget and developing and refining our internal projections for future periods;

● to evaluate the effectiveness of our business strategies and as a supplemental tool in evaluating our performance against our budget for each period;

● in communication with our board of directors and investors concerning our financial performance;

● to evaluate prior acquisitions in relation to the existing business; and

● to evaluate comparative net sales performance in prior and future periods.

We believe that the disclosure of Adjusted EBITDA offers an additional financial metric which, when coupled with U.S. GAAP results and the reconciliation to U.S. GAAP results, provides a more complete understanding of our results of operations and the factors and trends affecting our business for securities analysts, investors and other interested parties in the evaluation of our company. We believe Adjusted EBITDA is useful to investors for the following reasons:

● Adjusted EBITDA and similar non-GAAP measures are widely used by investors to measure a company’s operating performance without regard to items that can vary substantially from company to company depending upon financing and accounting methods, book values of assets, tax jurisdictions, capital structures and the methods by which assets were acquired; and

● by comparing our Adjusted EBITDA in different historical periods, our investors can evaluate our operating performance excluding the impact of certain items.
