PLYMOUTH MEETING, Pa.–(BUSINESS WIRE)–Feb. 25, 2025– Harmony Biosciences Holdings, Inc. (Nasdaq: HRMY) today announced a record $201.3 million in net product revenues for the fourth quarter 2024, and full year 2024 net revenues of $714.7 million, ending the year with $576 million in cash, cash equivalents and investments on the balance sheet. The company has guided 2025 WAKIX® net revenues to $820 – $860 million, targeting a $1B+ opportunity with WAKIX in narcolepsy alone.

“2025 is set up to be a transformational year for Harmony, as our robust, late-stage pipeline comes into focus and we advance our long-term growth strategy,” said Jeffrey M. Dayno, M.D., President and Chief Executive Officer of Harmony Biosciences. “This year will bring major milestones for Harmony, with the topline data readout from our Phase 3 registrational trial with ZYN002 in Fragile X syndrome expected in Q3 and the potential, if successful, to bring the first approved treatment to the Fragile X patient community. In Q4, we will be initiating two Phase 3 registrational trials with our next gen Pitolisant HD formulation in both narcolepsy and idiopathic hypersomnia, potentially extending the pitolisant franchise out to the 2040s and further solidifying our leadership in sleep/wake. Taken together, these catalysts underscore the importance of 2025 as a pivotal year in Harmony’s long-term growth strategy. With at least one new product candidate or indication launch each year over the coming years, our pipeline has the potential to deliver over $3 billion in net revenue as the leading CNS company focused on developing and delivering innovative treatments for patients with unmet needs.”
