We closed the pivotal acquisition of Increlex, acquired another high-value rare disease product in Galzin, and boosted our product pipeline with the license of Amglidia and initiation of two exciting new internal development projects, ET-700 and ET-800. We completed all this while continuing to execute on our base business, delivering record product sales and our 16th straight quarter of sequential revenue growth,” said Sean Brynjelsen, CEO of Eton Pharmaceuticals. “We are poised for an acceleration of growth in 2025. Increlex was relaunched in January with our now fully dedicated pediatric endocrinology sales force and is already adding new patients at a pace well ahead of our expectations. Galzin was relaunched in March with our newly deployed metabolic sales force and has been well received by the Wilson disease community. Launch inventory for ET-400 has been manufactured and our team stands ready to launch the product within days of its PDUFA goal date of May 28, if approved. Finally, ET-600’s successful pivotal study results allow us to file an additional high-value NDA in the coming weeks.” concluded Brynjelsen. Fourth Quarter and Recent Business Highlights Delivered 16th straight quarter of sequential growth in product sales. Eton reported fourth quarter 2024 net sales of $11.6 million, an increase of 59% over the prior year period, driven primarily by strong growth of ALKINDI SPRINKLE® and Carglumic Acid. The company expects sequential growth in quarterly product revenue to continue through 2025 and beyond. Relaunched Increlex, which is tracking ahead of expectations. Increlex is a highly durable, complex biologic used for the treatment of an ultra-rare pediatric endocrinology condition that is estimated to impact approximately 200 children in the U.S. Eton closed the acquisition in late December and relaunched the product in the United States in January. The Company intends to leverage its existing sales team and relationships in the pediatric endocrinology community to promote the product and increase awareness of this underdiagnosed and undertreated condition. The launch has seen strong initial results, with numerous new patients added in January, February, and the first half of March. Awarded second patent for ET-400 and preparing for potential launch. During the fourth quarter, Eton was granted an additional patent for ET-400 by the United States Patent & Trademark Office (USPTO). The patent, which expires in 2043, covers hydrocortisone oral liquid formulations and is expected to be listed in the FDA’s Orange Book upon approval. The Company has successfully manufactured launch quantities for the product and its sales and promotional campaigns are ready to go live. If approved on its May 28 Prescription Drug User Fee Act (PDUFA) goal date, the Company anticipates being in position to quickly launch the product. Acquired and re-launched Galzin. In January, Eton added the ultra-rare disease commercial product Galzin to its metabolic portfolio. Seeing the need for improved patient experience, increased awareness, and broader access and affordability, the Company relaunched Galzin on March 3 with its newly deployed metabolic sales force and robust Eton Cares patient support service. The Eton Cares patient support program ensures patients can access Galzin with $0 co-pays, patient assistance, reimbursement support, and overnight shipments. Announced positive pivotal study results for ET-600 and the issuance of a patent. ET-600 passed its pivotal bioequivalence study, successfully demonstrating pharmacokinetic equivalence to the reference product. In addition, the Company was issued a patent covering the product’s proprietary formulation of desmopressin oral solution. The patent expires in 2044 and is expected to be listed in the FDA’s Orange Book upon the product’s approval. Eton is preparing to submit an NDA for ET-600 in April, which could allow for approval in the first quarter of 2026. Disclosed two new internal development programs, ET-700 and ET-800. The Company has two new, high-value product candidates under development internally. More details regarding these previously undisclosed programs will be shared during Eton’s Investor Day conference call. Acquired U.S. rights to Amglidia (glyburide oral suspension). Amglidia, which has been approved in the E.U. since 2018, is under development in the U.S. for the treatment of neonatal diabetes mellitus and has been granted Orphan Drug Designation by the FDA. Amglidia is a strong strategic fit with Eton’s existing pediatric endocrinology portfolio, and the Company is scheduled to meet with the FDA in April 2025 to discuss the product’s clinical pathway. Fourth Quarter Financial Results Net Revenue: Total net revenues for the fourth quarter of 2024 increased 59% to $11.6 million compared to $7.3 million in the prior year period, driven primarily by growth in ALKINDI SPRINKLE and Carglumic Acid. The Increlex and Galzin acquisitions closed in late December and contributed less than $0.2 million of revenue during the fourth quarter. Gross Profit: Gross profit for the fourth quarter of 2024 was $6.5 million, compared to gross profit of $3.6 million for the fourth quarter of 2023. The increase was primarily due to increased product sales. In addition, fourth quarter 2023 gross profit was negatively impacted by $1.0 million as a result of ALKINDI SPRINKLE net sales triggering a one-time commercial success-based milestone under the terms of the product’s licensing agreement. Research and Development (R&D) Expenses: R&D expenses for the fourth quarter of 2024 were $(0.9) million compared to $1.0 million in the prior year period. During the fourth quarter of 2024, Eton’s ET-400 product was granted Orphan Drug Designation by the FDA, which resulted in Eton receiving a refund of the NDA filing fee that was paid and expensed in the second quarter of 2024. General and Administrative (G&A) Expenses: G&A expenses for the fourth quarter of 2024 were $6.7 million compared to $4.6 million in the prior year period. The increase was primarily due to personnel additions and increased sales and marketing investments that were initiated in the fourth quarter of 2024 to support the 2025 launches of Increlex, Galzin, and ET-400, as well as Increlex related transaction costs. Net Loss: Net loss for the fourth quarter of 2024 was $0.6 million or $0.02 per basic and diluted share compared to a net loss of $2.3 million or $0.09 per basic and diluted share in the prior year period. Cash Position: As of December 31, 2024, Eton had cash and cash equivalents of $14.9 million.
