\nHarmony Biosciences Holdings, Inc. (Nasdaq: HRMY) today announced earnings with reported revenue of $243.8 million for Q4 2025, representing 21% year-over-year revenue growth for WAKIX\u00ae<\/sup>. For the full year 2025, the company generated $868.5 million in net product revenue, reflecting continued commercial strength as evidenced by six consecutive years of revenue growth and profitability. The company enters the year with significant momentum, reinforcing its profile as a profitable, self-funding biotech company with a robust, late-stage pipeline and strong long-term growth potential.<\/p>\n
\n\u201cWAKIX is on track to exceed $1 billion in revenue and achieve blockbuster status in 2026, reflecting the strength and durability of the pitolisant franchise. Based on this commercial success and our strong momentum, we see even greater opportunity for pitolisant going forward,\u201d said Jeffrey M. Dayno, M.D., President and Chief Executive Officer of Harmony Biosciences. \u201cThe next-generation formulations of pitolisant are designed to grow our leadership in sleep-wake, extend the lifecycle of pitolisant into the 2040\u2019s, expand into additional orphan\/rare indications, and now broaden our reach beyond orphan\/rare into larger CNS patient populations. Our robust late-stage pipeline, including five ongoing Phase 3 registrational trials across five distinct CNS indications, positions Harmony for multiple near-term catalysts and meaningful long-term value creation.\u201d<\/p>\n

Non-GAAP adjusted net income, which we believe better reflects our core business performance, was $33.4 million ($0.57 per diluted share) for the fourth quarter of 2025 versus $64.2 million ($1.10 per diluted share) for the comparable 2024 period.<\/p>\n \nReconciliations of applicable GAAP financial measures to Non-GAAP financial measures are included at the end of this press release.<\/p>\n \nHarmony\u2019s operating expenses include the following:<\/p>\n Full Year 2025 Financial Results \nGAAP net income for the year ended December 31, 2025, was $158.7 million, or $2.71 earnings per diluted share, compared to GAAP net income of $145.6 million, or $2.51 earnings per diluted share, for the same period in 2024. Non-GAAP adjusted net income was $211.0 million, or $3.60 earnings per diluted share, for the year ended December 31, 2025, compared to Non-GAAP adjusted net income of $196.7 million, or $3.40 per diluted share, for the same period in 2024.<\/p>\n \nReconciliations of applicable GAAP financial measures to Non-GAAP financial measures are included at the end of this press release.<\/p>\n \nHarmony\u2019s operating expenses included the following:<\/p>\n \nAs of December 31, 2025, Harmony had cash, cash equivalents and investments of $882.5 million, compared to $576.1 million as of December 31, 2024.<\/p>\n 2026 Net Product Revenue Guidance Conference Call Today at 8:30 a.m. ET \nTo participate in the live call by phone, dial 800-274-8461 (domestic) or 203-518-9814 (international), and reference passcode HRMYQ425.<\/p>\n Non-GAAP Financial Measures About WAKIX\u00ae<\/sup> (pitolisant) Tablets Indications and Usage<\/b><\/p>\n \nWAKIX is indicated for the treatment of excessive daytime sleepiness (EDS) or cataplexy in patients 6 years of age and older with narcolepsy.<\/p>\n Important Safety Information<\/b><\/p>\n Contraindications Warnings and Precautions \nThe risk of QT prolongation may be greater in patients with higher concentrations of pitolisant (e.g., patients with hepatic or renal impairment). Monitor patients with hepatic or renal impairment for increased QTc. Dosage modification is recommended in patients with moderate hepatic impairment and moderate or severe renal impairment. WAKIX is contraindicated in patients with severe hepatic impairment and not recommended in patients with end-stage renal disease (ESRD).<\/p>\n Adverse Reactions Drug Interactions \nConcomitant use of WAKIX with strong CYP3A4 inducers decreases exposure of pitolisant by 50%. Dosage adjustments may be required.<\/p>\n \nH1 receptor antagonists that cross the blood-brain barrier may reduce the effectiveness of WAKIX. Patients should avoid centrally acting H1 receptor antagonists.<\/p>\n \nWAKIX is a borderline\/weak inducer of CYP3A4. WAKIX may reduce the effectiveness of sensitive CYP3A4 substrates, including hormonal contraceptives. Patients using hormonal contraception should be advised to use an alternative non-hormonal contraceptive method during treatment with WAKIX and for at least 21 days after discontinuing treatment.<\/p>\n Use in Specific Populations \nThe safety and effectiveness of WAKIX have not been established for the treatment of excessive daytime sleepiness or cataplexy in pediatric patients less than 6 years of age with narcolepsy.<\/p>\n \nWAKIX is extensively metabolized by the liver. WAKIX is contraindicated in patients with severe hepatic impairment. Dosage adjustment is required in patients with moderate hepatic impairment.<\/p>\n \nWAKIX is not recommended in patients with end-stage renal disease. Dosage adjustment of WAKIX is recommended in patients with eGFR <60 mL\/minute\/1.73 m2.<\/p>\n \nThe maximum recommended dosage is lower in patients who are CYP2D6 poor metabolizers because these patients have higher pitolisant concentrations than CYP2D6 normal metabolizers and may have increased risk of adverse events.<\/p>\n \nPlease see the Full Prescribing Information<\/a> for WAKIX for more information.<\/p>\n \nTo report suspected adverse reactions, contact Harmony Biosciences at 1-800-833-7460 or the FDA at 1-800-FDA-1088 or www.fda.gov\/medwatch<\/a>.<\/p>\n About Narcolepsy About Idiopathic Hypersomnia About Clemizole Hydrochloride (EPX-100) About Dravet Syndrome About Lennox-Gastaut Syndrome About Harmony Biosciences Forward-Looking Statements HARMONY BIOSCIENCES HOLDINGS, INC.

Harmony Biosciences reported net product revenue of $243.8 million for the quarter ended December 31, 2025, compared to $201.3 million for the same period in 2024, representing 22% year-over-year growth. This performance reflects both continued demand for WAKIX within the large narcolepsy market opportunity (approximately 80,000 diagnosed patients in the U.S.) and the product’s broad clinical utility. The continued success has been driven by strong execution across the organization from sales effectiveness to marketing and promotion and supported by broad payer coverage and how the company supports patients over time.<\/p>\n\n
\n<\/b>
Net product revenues for the year ended December 31, 2025, were $868.5 million, compared to $714.7 million for the same period in 2024. The 22% growth versus the same period in 2024 is primarily attributed to strong commercial sales of WAKIX driven by continued organic demand tapping into a large market opportunity (approximately 80,000 patients diagnosed with narcolepsy in the U.S.) and the broad clinical utility of WAKIX across the approximately 9,000 HCPs that we call on (about 5,000 of whom do not participate in an oxybate REMS program).<\/p>\n\n

We are hosting our fourth quarter 2025 financial results conference call and webcast today, beginning at 8:30 a.m. Eastern time. The live and replay webcast of the call will be available on the investor relations page of our website https:\/\/ir.harmonybiosciences.com\/<\/a>.<\/p>\n
\n<\/b>
In addition to our GAAP results, we present certain Non-GAAP measures including Non-GAAP adjusted net income and Non-GAAP adjusted net income per share, which we believe provides important supplemental information to management and investors regarding our performance. These measurements are not a substitute for GAAP measurements, and the manner in which we calculate Non-GAAP adjusted net income and Non-GAAP adjusted net income per share may not be identical to the manner in which other companies calculate adjusted net income and adjusted net income per share. We use these Non-GAAP measurements as an aid in monitoring our financial performance from quarter-to-quarter and year-to-year and benchmarking against comparable companies. Non-GAAP financial measures should not be considered in isolation or as a substitute for comparable GAAP measures; should be read in conjunction with our consolidated financial statements prepared in accordance with GAAP; have no standardized meaning prescribed by GAAP; and are not prepared under any comprehensive set of accounting rules or principles. In addition, from time to time in the future there may be other items that we may exclude for purposes of our Non-GAAP financial measures; and we may in the future cease to exclude items that we have historically excluded for purposes of our Non-GAAP financial measures.<\/p>\n
\n<\/b>
WAKIX, a first-in-class medication, is approved by the U.S. Food and Drug Administration for the treatment of excessive daytime sleepiness (EDS) or cataplexy in patients 6 years of age and older with narcolepsy. It was granted orphan drug designation for the treatment of narcolepsy in 2010, and breakthrough therapy designation for the treatment of cataplexy in 2018. WAKIX is a selective histamine 3 (H\u2083) receptor antagonist\/inverse agonist. The mechanism of action of WAKIX is unclear; however, its efficacy could be mediated through its activity at H\u2083 receptors, thereby increasing the synthesis and release of histamine, a wake promoting neurotransmitter. WAKIX was designed and developed by Bioprojet (France). Harmony has an exclusive license from Bioprojet to develop, manufacture and commercialize pitolisant in the United States.<\/p>\n
\n<\/b>
WAKIX is contraindicated in patients with known hypersensitivity to pitolisant or any component of the formulation. Anaphylaxis has been reported. WAKIX is also contraindicated in patients with severe hepatic impairment.<\/p>\n
\n<\/b>
WAKIX prolongs the QT interval; avoid use of WAKIX in patients with known QT prolongation or in combination with other drugs known to prolong the QT interval. Avoid use in patients with a history of cardiac arrhythmias, as well as other circumstances that may increase the risk of the occurrence of torsade de pointes or sudden death, including symptomatic bradycardia, hypokalemia or hypomagnesemia, and the presence of congenital prolongation of the QT interval.<\/p>\n
\n<\/b>
In the placebo-controlled clinical trials conducted in patients with narcolepsy with or without cataplexy, the most common adverse reactions (\u22655% and at least twice placebo) for WAKIX were insomnia (6%), nausea (6%), and anxiety (5%). Other adverse reactions that occurred at \u22652% and more frequently than in patients treated with placebo included headache, upper respiratory tract infection, musculoskeletal pain, heart rate increased, hallucinations, irritability, abdominal pain, sleep disturbance, decreased appetite, cataplexy, dry mouth, and rash. In the placebo-controlled phase of the clinical trial conducted in pediatric patients 6 years and older with narcolepsy with or without cataplexy, the most common adverse reactions (\u22655% and greater than placebo) for WAKIX were headache (19%) and insomnia (7%). The overall adverse reaction profile of WAKIX in the pediatric clinical trial was similar to that seen in the adult clinical trial program.<\/p>\n
\n<\/b>
Concomitant administration of WAKIX with strong CYP2D6 inhibitors increases pitolisant exposure by 2.2-fold. Reduce the dose of WAKIX by half.<\/p>\n
\n<\/b>
There is a pregnancy exposure registry that monitors pregnancy outcomes in women who are exposed to WAKIX during pregnancy. Patients should be encouraged to enroll in the WAKIX pregnancy registry if they become pregnant. To enroll or obtain information from the registry, patients can call 1-800-833-7460.<\/p>\n

Narcolepsy is a rare, chronic, debilitating neurological disease of sleep-wake state instability that impacts approximately 170,000 Americans and is primarily characterized by excessive daytime sleepiness (EDS) and cataplexy \u2013 its two cardinal symptoms \u2013 along with other manifestations of REM sleep dysregulation (hallucinations and sleep paralysis), which intrude into wakefulness. EDS is the inability to stay awake and alert during the day and is the symptom that is present in all people living with narcolepsy. In most patients, narcolepsy is caused by the loss of hypocretin\/orexin, a neuropeptide in the brain that supports sleep-wake state stability. This disease affects men and women equally, with typical symptom onset in adolescence or young adulthood; however, it can take up to a decade to be properly diagnosed.<\/p>\n
\n<\/b>
Idiopathic Hypersomnia (IH) is a rare and chronic neurological disease that is characterized by excessive daytime sleepiness (EDS) despite sufficient or even long sleep time. EDS in IH cannot be alleviated by naps, longer sleep or more efficient sleep. People living with IH experience significant EDS along with the symptoms of sleep inertia (prolonged difficulty waking up from sleep) and ‘brain fog’ (impaired cognition, attention, and alertness). The cause of IH is unknown, but it is likely due to alterations in areas of the brain that stabilize states of sleep and wakefulness. IH is one of the central disorders of hypersomnolence and, like narcolepsy, is a debilitating sleep disorder that can result in significant disruption in daily functioning.<\/p>\n
\n<\/b>
EPX-100, clemizole hydrochloride, is under development for the treatment of Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS). EPX-100 acts by targeting central 5-hydroxytryptamine receptors to modulate serotonin signaling. The drug candidate is administered orally twice a day in a liquid formulation and has been developed based on a proprietary phenotype-based zebrafish drug screening platform.DS is caused by a loss of function mutation in the SCN1A gene, and scn1 mutant zebrafish replicate the genetic etiology and phenotype observed in the majority of DS patients. The scn1Lab mutant zebrafish model that expresses voltage gated sodium channels has been used for high-throughput screening of compounds that modulate Nav1.1 in the central nervous system.<\/p>\n
\n<\/b>
Dravet syndrome (DS) is a severe and progressive epileptic encephalopathy that begins in infancy and causes significant impact on patient functioning. DS begins in the first year of life and is characterized by high seizure frequency and severity, intellectual disability, and a risk of sudden unexpected death in epilepsy. Approximately 85% of Dravet syndrome cases are caused by de novo loss-of-function (LOF) mutations in a voltage-gated sodium channel gene, SCN1A1. DS has an estimated incidence rate of 1:15,700.<\/p>\n
\n<\/b>
Lennox-Gastaut syndrome (LGS) is a rare and drug-resistant epileptic encephalopathy characterized by onset in children between 3-5 years of age. The underlying cause of LGS is unknown and can be related to a wide range of factors including genetic differences and structural differences in the brain.As a result, patients experience multiple seizure types, including atonic seizures, and developmental, cognitive, and behavioral issues. LGS affects approximately 48,000 patients in the U.S.<\/p>\n
