(Nasdaq: HRMY) today reported Q2 2026 net revenue for WAKIX® (pitolisant) of $261.3 million, delivering 30% year-over-year growth in its seventh year on the market. These results underscore continued strong demand for WAKIX, disciplined commercial execution across the franchise and sustained momentum through the first half of 2026. Average patients for the quarter were approximately 8,950, an increase in average patients of 450. WAKIX remains on track to achieve full-year net revenue guidance of $1.0 billion to $1.04 billion. The Company also announced encouraging single ascending dose (SAD) data from its Phase 1 study of BP-205, demonstrating favorable pharmacokinetic (PK) and safety/tolerability profiles that reinforce Harmony’s conviction in BP-205 as a potential best-in-class orexin-2 receptor (OX2R) agonist. These data support Harmony’s robust orexin development strategy, including initiating Phase 2 studies beginning in mid-2027 to evaluate multiple CNS indications. “Our record second-quarter revenue reflects sustained demand for WAKIX and keeps us firmly on track to deliver over $1 billion in revenue this year. With this strong foundation, we are aggressively advancing our pipeline, with our orexin-2 agonist BP-205 as the centerpiece, that we believe can create significant long-term value for both patients and shareholders,” said Jeffrey M. Dayno, MD, President and Chief Executive Officer of Harmony Biosciences. “The Phase 1 clinical PK and safety/tolerability data for BP-205 that we shared today, together with pre-clinical data demonstrating the highest potency of any orexin-2 agonist currently in the clinic, reinforce our conviction that BP-205 has the potential to be the best-in-class orexin-2 agonist with broad clinical utility across multiple CNS indications.” Bruce C. Corser, MD, Medical Director of the Sleep Management Institute, said, “The Phase 1 single ascending dose pharmacokinetic and safety/tolerability data for BP-205 are compelling. The potential for rapid onset of action and once-daily dosing, along with a favorable safety/tolerability profile, exceptional potency and high selectivity, suggests that BP-205 may have potential clinical utility in indications beyond orexin deficiency. I look forward to following the continued clinical development of this program.” Key Drivers of Value Creation Continued WAKIX Growth in an Evolving Market Second Quarter 2026 Net Product Revenue for WAKIX Net product revenue for the quarter ended June 30, 2026, was $261.3 million, representing 30% growth vs 2Q25  Estimated average number of patients grew 450 to 8,950 in Q2, which is the 2nd highest average patient growth ever Executed expansion of field sales, remote sales, field reimbursement and patient outreach teams with all roles hired, trained and fully deployed in 2Q Launched online portal and changes to reimbursement support process to enable patients to secure WAKIX faster and with higher success rate On Track to Achieve 2026 WAKIX Net Revenue Guidance of $1.0 Billion to $1.04 Billion Advance a Robust, Self-Funded Pipeline Orexin-2 receptor agonist BP-205 (BP1.15205) is Harmony’s OX2R agonist discovered by Teijin Pharma and developed in partnership with Bioprojet. It is designed to deliver a differentiated profile through its high potency, excellent selectivity, favorable safety/tolerability, and a predictable PK profile with the potential for once-a-day dosing. It is the most potent OX2R agonist currently in clinical development.

This performance reflects continued strong demand for WAKIX within the large narcolepsy market opportunity (approximately 80,000 diagnosed patients in the U.S.), disciplined commercial execution across the franchise and the product's broad clinical utility. The continued success of WAKIX has been driven by strong demand and commercial execution. Based on our results for the first half of 2026, WAKIX remains on track to achieve full-year net revenue of $1.0 billion to $1.04 billion. Cost of product sold was $63.2 million in the second quarter of 2026, or 24.2% as a percentage of net product revenue, as compared to $38.2 million, or 19.0%, for the same quarter in 2025, representing a 66% increase. The increase in cost of product sold as a percentage of net product revenue was primarily driven by new royalties related to the Novitium license agreement. Net income for the second quarter was $75.4 million, or $1.28 per diluted share, compared to $39.8 million, or $0.68 per diluted share, for the same quarter in 2025. Harmony’s operating expenses include the following: Research and Development expenses were $46.6 million in the second quarter of 2026, as compared to $50.2 million for the same quarter in 2025, representing a 7% decrease; this was primarily driven by a $15.0 million up-front payment related to the agreement with CiRC that was entered into during the second quarter of 2025, for which there was no corresponding amount in the current year period; Sales and Marketing expenses were $34.1 million in the second quarter of 2026, as compared to $30.1 million for the same quarter in 2025, representing a 13% increase, primarily driven by the expansion of our field-based teams; General and Administrative expenses were $28.1 million in the second quarter of 2026, as compared to $33.9 million for the same quarter in 2025, representing a 17% decrease; this was primarily driven by a charge related to an ANDA settlement in the second quarter of 2025, for which there was no corresponding amount in the current year period; and Total Operating expenses were $108.8 million in the second quarter of 2026, as compared to $114.2 million for the same quarter in 2025, representing a 5% decrease As of June 30, 2026, Harmony had cash, cash equivalents and investments of $962.5 million, compared to $882.5 million as of December 31, 2025. 2026 Net Product Revenue Guidance Reiterated 2026 WAKIX net revenue guidance of $1.0 billion to $1.04 billion.
