During the second quarter, we received FDA approval for and subsequently launched KHINDIVI, marking our third commercial launch in 2025. As the first and only FDA-approved oral solution of hydrocortisone, KHINDIVI is a game changer for many pediatric patients. We were excited to finally bring this important treatment to the market and look forward to continuing to raise awareness of its availability,” said Sean Brynjelsen , CEO of Eton Pharmaceuticals . “Our strong commercial execution helped us deliver an impressive 108% revenue growth in the quarter, driven primarily by ongoing growth from ALKINDI SPRINKLE and the relaunches of INCRELEX and GALZIN. INCRELEX continues to track well ahead of our original expectations with 100 active patients at the end of July. We previously expected to reach this mark at the end of the year, so we are proud of the team’s hard work to hit this milestone well ahead of schedule. With these recent successes and the ongoing strength of our entire portfolio, we now expect to achieve an $80 million annual revenue run rate in the third quarter, one quarter ahead of our prior projections.” “In addition to executing on these three product launches and driving significant revenue growth, we continue to advance our pipeline programs, evaluate new business development opportunities and prepare for the potential approval and launch of ET-600 in the first quarter of 2026,” concluded Brynjelsen. Second Quarter and Recent Business Highlights 18th straight quarter of sequential growth in product sales and 108% growth over prior year quarter. Eton reported second quarter 2025 product sales of $18.9 million . Year-over-year revenue growth was driven primarily by continued growth in ALKINDI SPRINKLE® and the addition of revenues from INCRELEX and GALZIN. INCRELEX relaunch outperforming expectations; reached 100 active patients at the end of July. Eton’s ongoing engagement with the pediatric endocrinology community has helped drive awareness and clinical adoption of INCRELEX. The Company had a robust presence at key scientific conferences during the quarter, including Pediatric Endocrine Nurses Society (PENS), Pediatric Endocrine Society (PES), and Endocrine Society (ENDO), where it met with multiple advisory boards and Key Opinion Leaders, participated in a product symposium, hosted exhibit booths, and presented a new scientific poster featuring real-world registry data demonstrating the efficacy and safety of INCRELEX. Due to the strong execution of Eton’s commercial organization, INCRELEX has grown from 67 active patients in December 2024 to 100 active patients at the end of July, a target the Company initially expected to reach at the end of 2025. FDA approval and commercial launch of KHINDIVI, Eton’s 8th commercial product. On May 28th , Eton received FDA approval for KHINDIVI as a replacement therapy in pediatric patients five years of age and older with adrenocortical insufficiency. The product became commercially available in June, and the Company has received favorable early feedback from patients and prescribers. Eton is also working to develop a new formulation for patients aged four years and under. Eton has already manufactured registration batches of a new KHINDIVI formulation with substantially reduced levels of the inactive ingredients polyethylene glycol 400, propylene glycol, and glycerin, which Eton believes will allow for an expansion of the product’s approved population age. A pre-submission meeting with the FDA is scheduled for September, and the Company expects to file a supplement to the existing KHINDIVI New Drug Application (NDA) in the first half of 2026, which could allow for approval before the end of 2026. Continued growth of ALKINDI SPRINKLE. In the second quarter, ALKINDI SPRINKLE delivered strong sequential and year-over-year growth in revenue and patients on treatment. Through the second quarter, year-to-date new patient prescriptions exceeded the first two quarters of all prior years. In recent months, Eton had a prominent footprint at major healthcare professional congresses such as PENS, PES, ENDO, and Pediatric Endocrinology Society of Texas , Oklahoma , Louisiana , Arkansas (PESTOL), where the Company presented a new scientific poster showcasing real-world ALKINDI SPRINKLE safety and adherence data. Strong initial trajectory for GALZIN commercial relaunch. Eton relaunched GALZIN in March and believes it has now successfully transitioned most existing users to Eton’s distribution network. The Company’s launch has been well received by the Wilson disease community, which has expressed excitement about Eton’s efforts to broaden access to treatment with its $0 copay for eligible patients and high-touch specialty pharmacy distribution to help support medication adherence. The Company sees a significant long-term growth opportunity and has launched awareness and educational campaigns to target patients that have historically used over-the-counter zinc supplement products that are not FDA-approved for Wilson disease. NDA for ET-600 accepted by the FDA and second patent received. In July, ET-600's NDA was accepted for review by the FDA and assigned a Target Action Date of February 25, 2026 . Commercialization activities are already underway in anticipation of a potential first quarter 2026 launch. Also in July, the United States Patent and Trademark Office (USPTO) granted the Company a second patent covering ET-600's proprietary formulation of desmopressin oral solution. The patent expires in 2044 and is expected to be listed in the FDA Orange Book upon the product’s approval. Second Quarter Financial Results Net Revenue: Net revenues for the second quarter of 2025 were $18.9 million compared with $9.1 million in the prior year period, an increase of 108%. The growth was driven primarily by increased sales of ALKINDI SPRINKLE and the addition of sales from INCRELEX and GALZIN. The company now expects to achieve an approximately $80 million annual revenue run rate in the third quarter of 2025, one quarter ahead of previous projections. Gross Profit: Gross profit for the second quarter of 2025 was $11.9 million compared with $5.6 million in the prior year period, an increase of 112%. Adjusted gross profit, which adjusts for the impact of acquired inventory step-up adjustments and intangible amortization, was $14.1 million in the second quarter of 2025, representing an adjusted gross margin of 75% compared to adjusted gross profit of $5.9 million and adjusted gross margin of 65% in the prior year period. The margin improvement was primarily driven by continued growth of higher-margin ALKINDI SPRINKLE and the addition of high margin INCRELEX revenue. The Company continues to expect to report full year 2025 adjusted gross profit of approximately 70%. Research and Development (R&D) Expenses: R&D expenses for the second quarter of 2025 were $3.7 million compared to $3.0 million in the prior year period. R&D expenses for the second quarter of 2025 included a $2.2 million expense for the FDA application fee associated with the submission of the Company’s NDA for ET-600 and a $0.5 million expense related to the licensing of AMGLIDIA®.General and Administrative (G&A) Expenses: G&A expenses for the second quarter of 2025 were $9.7 million compared to $5.6 million in the prior year period. The increase was primarily attributable to an increase in sales and marketing expenses associated with the ongoing product launches and an increase in compensation and benefit expenses due to an increase in general and administrative headcount. Adjusted G&A expense, which removes share-based compensation, transaction related costs, and other one-time expenses, was $7.6 million in the quarter, compared with $4.9 million the prior year period. The Company expects Adjusted G&A expenses to remain flat or decline through the second half of 2025. Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (Adjusted EBITDA): Adjusted EBITDA for the second quarter of 2025 was $3.1 million compared to $(1.6) million in the prior year period. Net Income/Loss: Net loss for the second quarter of 2025 was $2.6 million or $0.10 per basic and diluted share compared to a net loss of $3.0 million or $0.12 per basic and diluted share in the prior year period. On a non-GAAP basis, the Company reported net income of $1.5 million or $0.03 per diluted share, for the second quarter of 2025 compared to a net loss of $1.9 million , or $0.08 per diluted share in the prior year period. For a reconciliation of GAAP net loss to Earnings Before Interest, Taxes, Depreciation and Amortization EBITDA (“EBITDA”), Adjusted EBITDA and adjusted Non-GAAP basic and fully diluted earnings per share to the most directly comparable GAAP financial measure, please see the tables below. Cash Position: As of June 30, 2025 , the Company had cash and cash equivalents of $25.4 million and generated $8.0 million of operating cash flow during the quarter. Subsequent to the second quarter, Eton received a $4.6 cash payment for the INCRELEX ex- U.S. licensing agreement executed in the first quarter.

Forward-Looking Statements Statements contained in this press release regarding matters that are not historical facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including statements associated with the expected ability of Eton to undertake certain activities and accomplish certain goals and objectives. These statements include but are not limited to statements regarding Eton’s business strategy, Eton’s plans to develop and commercialize its product candidates, the safety and efficacy of Eton’s product candidates, Eton’s plans and expected timing with respect to regulatory filings and approvals, and the size and growth potential of the markets for Eton’s product candidates. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Words such as “believes,” “anticipates,” “plans,” “expects,” “intends,” “will,” “goal,” “potential” and similar expressions are intended to identify forward-looking statements. These forward-looking statements are based upon Eton’s current expectations and involve assumptions that may never materialize or may prove to be incorrect. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of various risks and uncertainties, which include, without limitation, risks associated with the process of discovering, developing and commercializing drugs that are safe and effective for use as human therapeutics, and in the endeavor of building a business around such drugs. These and other risks concerning Eton’s development programs and financial position are described in additional detail in Eton’s filings with the Securities and Exchange Commission . All forward-looking statements contained in this press release speak only as of the date on which they were made. Eton undertakes no obligation to update such statements to reflect events that occur or circumstances that exist after the date on which they were made. Non-GAAP Financial Measures In addition to the Company’s results of operations determined in accordance with U.S. generally accepted accounting principles (GAAP), which are presented and discussed above, management also utilizes Adjusted EBITDA, an unaudited financial measure that is not calculated in accordance with GAAP, to evaluate the Company’s financial results and performance and to plan and forecast future periods. Adjusted EBITDA is considered a “non-GAAP” financial measure within the meaning of Regulation G promulgated by the SEC . Management believes that this non-GAAP financial measure reflects an additional way of viewing aspects of the Company’s operations that, when viewed with GAAP results, provides a more complete understanding of the Company’s results of operations and the factors and trends affecting its business. Management believes Adjusted EBITDA provides meaningful supplemental information regarding the Company’s performance because (i) it allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making; (ii) it excludes the impact of non-cash or, when specified, non-recurring items that are not directly attributable to the Company’s core operating performance and that may obscure trends in the Company’s core operating performance; and (iii) it is used by institutional investors and the analyst community to help analyze the Company’s results. However, Adjusted EBITDA and any other non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP. Further, non-GAAP financial measures used by the Company and the way they are calculated may differ from the non-GAAP financial measures or the calculations of the same non-GAAP financial measures used by other companies, including the Company’s competitors. Adjusted EBITDAThe Company defines Adjusted EBITDA as net loss, excluding the effects of stock-based compensation and expenses, interest, taxes, depreciation, amortization, investment loss, net, and, if any and when specified, other non-recurring income or expense items. Management believes that the most directly comparable GAAP financial measure to Adjusted EBITDA is net loss. Adjusted EBITDA has limitations and should not be considered as an alternative to gross profit or net loss as a measure of operating performance or to net cash provided by (used in) operating, investing, or financing activities as a measure of ability to meet cash needs.
