Rhea-AI Filing Summary

Harmony Biosciences Holdings, Inc. reported record Q2 2026 results, with net product revenue of $261.3 million for WAKIX, representing 30% year-over-year growth and supporting reiterated 2026 WAKIX net revenue guidance of $1.0 billion to $1.04 billion.

Average treated patients were about 8,950, an increase of 450. Cost of product sold was $63.2 million, or 24.2% of net product revenue, primarily reflecting new royalties related to the Novitium license agreement. Net income was $75.4 million, or $1.28 per diluted share, compared with $39.8 million, or $0.68, in Q2 2025. As of June 30, 2026, cash, cash equivalents and investments totaled $962.5 million, and stockholders’ equity was $999.2 million versus $870.2 million at year-end 2025.

The company also highlighted pipeline and regulatory progress. Phase 1 single ascending dose data for orexin-2 agonist BP-205 showed favorable pharmacokinetic and safety/tolerability profiles, with additional Phase 1 and Phase 2 studies planned through 2027. The NDA for Pitolisant GR was accepted with a target PDUFA date of April 1, 2027, while Pitolisant HD is expected to deliver Phase 3 topline data in 2027 and has a target PDUFA date in 2028.

PDUFA date regulatory
"Pitolisant GR NDA accepted in July; Target PDUFA Date April 1, 2027"
PDUFA date is the deadline the U.S. Food and Drug Administration sets to complete its review of a drug or biologic application and decide whether to approve it. Investors watch it like a court verdict date: the decision can unlock sales and growth if approved or sharply reduce expected value if denied, so markets often move significantly as the date approaches or when the outcome is announced.
IND regulatory
"BP-205 IND Open in US; Initiating Phase 1b Study in Sleep-Deprived Healthy Volunteers"
single ascending dose medical
"encouraging single ascending dose (SAD) data from its Phase 1 study of BP-205"
A single ascending dose is a method used in testing new medicines where small amounts are given to participants, gradually increasing each time to find the safest and most effective dose. For investors, it provides important information about a drug’s safety and potential, helping gauge the progress and prospects of a pharmaceutical development.
orexin-2 receptor agonist medical
"potential best-in-class orexin-2 receptor (OX2R) agonist with broad clinical utility"
A drug that activates orexin-2 receptors — specific brain proteins that help control wakefulness and the sleep–wake switch — to promote alertness or stabilize sleep patterns; think of it as flipping a light switch that keeps the brain’s wake circuit on. Investors care because clinical trial outcomes, safety results and regulatory approvals determine whether the medicine can win market share in large sleep- and alertness-related markets, which can materially affect a developer’s value.
comprehensive income financial
"UNAUDITED CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS AND COMPREHENSIVE INCOME"
Comprehensive income is the total change in a company’s value in a reporting period that comes from everyday operations plus other gains or losses not shown on the regular profit-and-loss statement. Think of net income as the visible money earned this year and comprehensive income as that money plus hidden adjustments—such as currency swings, unrealized gains or losses on investments, and pension revaluations—that also affect shareholders’ stake and help investors see the fuller financial picture.
Net product revenue $261,280 (in thousands) 30% year-over-year growth vs $200,489 (in thousands) in 2025

Conference Call and Webcast Today at 8:30 a.m. ET

PLYMOUTH MEETING, Pa., August 4, 2026 /Business Wire/ -- Harmony Biosciences Holdings, Inc. (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.”

Second Quarter 2026 Financial Results

Harmony Biosciences reported net product revenue of $261.3 million for the quarter ended June 30, 2026, compared to $200.5 million for the same period in 2025, representing 30% year-over-year growth. 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.
