DEER PARK, Ill., Nov. 12, 2024 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals, Inc ("Eton" or "the Company") (NASDAQ:ETON), an innovative pharmaceutical company focused on developing and commercializing treatments for rare diseases, today reported financial results for the quarter ended September 30, 2024.

"Our strong product revenue growth in the third quarter allowed us to achieve positive GAAP net income from product revenue for the first time in the Company's history and we're pleased to reach this important milestone one quarter ahead of our original goal. We are proud of our ability to continue delivering exceptional growth, as demonstrated by our 15^th straight quarter of sequential growth in product revenue, while managing the bottom line," said Sean Brynjelsen, CEO of Eton Pharmaceuticals.

"This milestone is just the beginning of Eton's growth story. With the upcoming close of the Increlex acquisition and our ET-400 PDUFA date approaching, 2025 is shaping up to be a transformational year for Eton. We are very excited about what we can achieve in the coming quarters and years," concluded Brynjelsen.

Third Quarter and Recent Business Highlights

Delivered 15^thstraight quarter of sequential growth in product sales and reported positive GAAP net income. Eton reported third quarter 2024 product sales of $9.8 million, representing 40% growth over the prior year period, and 8% over the second quarter of 2024, driven primarily by the ongoing growth of ALKINDI SPRINKLE® and Carglumic Acid. During the quarter, Eton produced positive GAAP net income for the first time in Company history from product revenue alone.

Entered into an asset purchase agreement to acquire Increlex® (mecasermin injection) from Ipsen S.A. The transaction, which was announced in October, will add a high-value biologic product to the Company's commercial portfolio. The product is synergistic with Eton's existing pediatric endocrinology call point, and the acquisition is expected to be accretive to 2025 earnings. The Company anticipates the transaction closing near year-end 2024.

New Drug Application (NDA) for ET-400 accepted by the U.S. Food and Drug Administration (FDA). In July, the FDA accepted Eton's NDA for ET-400, its proprietary patented formulation of hydrocortisone oral solution and assigned the application a Prescription Drug User Fee Act (PDUFA) target action date of February 28, 2025. Eton expects to manufacture product inventory in the fourth quarter of 2024 to enable a commercial launch promptly after the expected approval in 2025. The Company believes the introduction of ET-400 will enable it to capture a greater percentage of the oral hydrocortisone market and, together with ALKINDI SPRINKLE, the two products are expected to achieve combined peak sales of more than $50 million annually.

Granted additional patent for ET-400. On November 5, Eton was granted an additional patent for ET-400 by the United States Patent & Trademark Office (USPTO), further strengthening the IP protection for the product. The patent, which expires in 2043, covers hydrocortisone oral liquid formulations and is expected to be listed in the FDA's Orange Book upon ET-400's approval.

Strong growth of ALKINDI SPRINKLE and the Company's metabolic portfolio. ALKINDI SPRINKLE reported 55% year-over-year revenue growth in Q3 2024. Carglumic Acid also reported another quarter of strong sequential and year-over-year growth. The commercial availability of Betaine Anhydrous, Nitisinone, and PKU GOLIKE® has helped increase the frequency of the Company's interactions with potential Carglumic Acid prescribers.

Initiation of ET-600 pivotal study. ET-600's pivotal bioequivalence study has been initiated. ET-600 is under development for the treatment of the pediatric endocrinology condition diabetes insipidus. If the study results are positive, Eton anticipates submitting an NDA for the product in the first quarter of 2025.

Third Quarter Financial Results

Net Revenue: Net sales for the third quarter of 2024 were $10.3 million compared to $7.0 million in the prior year period. Net sales in the current year period included $0.5 million of licensing payments received from out-licensing of the company's DS-200 product.

Product sales and royalty revenue were $9.8 million for the third quarter of 2024, an increase of 40% compared to $7.0 million in the prior year period, and an increase of 8% over the second quarter of 2024. The year-over-year increase in product sales revenue was primarily driven by growth in ALKINDI SPRINKLE and Carglumic Acid.

Gross Profit: Gross profit for the third quarter of 2024 was $6.3 million compared to $4.4 million in the prior year period.

Research and Development (R&D) Expenses: R&D expenses for the third quarter of 2024 were $0.5 million compared to $0.6 million in the prior year period as a result of decreased expenses associated with ET-400 project development activities.

General and Administrative (G&A) Expenses: G&A expenses for the third quarter of 2024 were $5.3 million compared to $4.3 million in the prior year period, mainly due to increased sales and marketing activities, legal expenses, and employee-related expenses.

Net Income: Net income for the third quarter of 2024 was $0.6 million or $0.02 per basic and diluted share. In the prior year period, net loss was $0.6 million, or $0.02 per basic and diluted share.

Cash Position: As of September 30, 2024, Eton had cash and cash equivalents of $20.3 million. The Company generated $2.9 million of operating cash flow during the quarter. The Company expects to generate positive cash flow in the fourth quarter and to fund its acquisition of Increlex with cash on hand and an expansion of its existing credit facility.
