1.b. Last Insights on ETON

The recent 3 months performance of Eton Pharmaceuticals, Inc. was negatively impacted by the extension of the PDUFA goal date for ET-400, pushing the new approval date to May 28, 2025. Additionally, the company's acquisition and relaunch of Increlex, a pediatric endocrinology biologic, was offset by the out-licensing of commercial rights to Increlex in territories outside of the U.S. to Esteve Pharmaceuticals, S.A. The company's patent portfolio expansion with the issuance of a new U.S. patent for ET-600 provided some positive news, but the overall performance was marred by the delay in ET-400's approval.

2. Eton Pharmaceuticals' Q3 2025 Earnings: Strong Revenue Growth and Pipeline Progress

Eton Pharmaceuticals reported a significant increase in product revenue for Q3 2025, with $22.5 million in sales, representing a 129% year-over-year growth and a 19% sequential increase. However, the company's adjusted gross margin was negatively impacted by INCRELEX ex U.S. related costs, resulting in a 38% decline in adjusted gross profit to $6.4 million. The earnings per share (EPS) came in at -$0.07, missing estimates of $0.16.

Publication Date: Nov -18

📋 Highlights
  • Revenue Growth:: Q3 2025 product revenue reached $22.5M, a 129% YoY increase and 19% QoQ growth.
  • Cash Flow & Margin Control:: Generated $12M in cash from operations and reduced adjusted SG&A expenses by $2.8M sequentially.
  • EBITDA Expansion:: Adjusted EBITDA rose to $2.9M (45% YoY), offset by non-recurring INCRELEX ex-U.S. costs; expects stronger margins ahead.
  • Product Performance:: ALKINDI SPRINKLE drove 19th consecutive quarter of growth, while INCRELEX exceeded projections with 10 new patients targeted by year-end.
  • Future Pipeline & Cash Position:: $37M cash balance supports acquisitions; expects 70%+ adjusted gross margin in Q4 2025 and >75% by 2028.

Revenue Growth Drivers

The revenue growth was primarily driven by strong sales of ALKINDI SPRINKLE, Carglumic Acid, INCRELEX, and GALZIN. ALKINDI SPRINKLE continued its reliable growth trend, while Carglumic Acid saw a year-over-year increase due to new patient adds. INCRELEX revenue and patient count continue to track well ahead of original projections, driven by market education and awareness efforts.

Pipeline Progress and Future Expectations

Eton Pharmaceuticals made significant progress on its pipeline products, including ET-700, an extended-release version of GALZIN, and ET-600, an oral solution of desmopressin to treat central diabetes insipidus, which was accepted by the FDA for review with a February 25 PDUFA date. The company expects continued strong revenue growth from its commercial products and attractive pipeline and label expansion opportunities.

Valuation and Outlook

With a P/S Ratio of 6.58 and an expected revenue growth rate of 36.7% next year, the company's valuation appears to be partially justified by its growth prospects. However, the negative EPS and high P/B Ratio of 20.07 may indicate overvaluation. The company's guidance for gross margins to reach north of 75% by 2028, driven by a shift in product revenue growth towards higher-margin products, is a positive factor.

Cash Flow and Balance Sheet

Eton Pharmaceuticals generated $12 million in cash from operations in Q3 2025 and finished the quarter with $37.1 million in cash on hand. The company's ability to finance acquisitions and drive growth through business development transactions is supported by its diversified and growing business, which is already generating strong EBITDA.
