Fourth Quarter 2023 Financial Results Net product revenue for the quarter ended December 31, 2023 was $168.4 million, compared to $128.3 million for the same period in 2022. The 31% growth versus the same period in 2022 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 US). The average number of patients on WAKIX increased by approximately 350 sequentially to approximately 6,150 for the quarter ended December 31, 2023. GAAP net income for the quarter ended December 31, 2023, was $26.6 million, or $0.45 per diluted share, compared to GAAP net income of $48.5 million, or $0.79 per diluted share, for the same period in 2022. Non-GAAP adjusted net income was $42.8 million, or $0.73 per diluted share, for the quarter ended December 31, 2023, compared to Non-GAAP adjusted net income of $61.9 million, or $1.01 per diluted share, for the same period in 2022. Reconciliations of applicable GAAP financial measures to Non-GAAP financial measures are included at the end of this press release. Harmony’s operating expenses include the following: Research and Development expenses were $30.3 million in the fourth quarter of 2023, as compared to $10.1 million for the same quarter in 2022, representing a 200% increase.

Expenses in the fourth quarter of 2023 included one-time Zynerba transaction related costs of $3.8 million; andTotal Operating Expenses were $85.1 million in the fourth quarter of 2023, as compared to $53.8 million for the same quarter in 2022, representing a 58% increase. Total Operating Expenses in the fourth quarter of 2023 included one-time Zynerba transaction related costs of $9.8 million. Full Year 2023 Financial Results Net product revenue for the year ended December 31, 2023 was $582.0 million, compared to $437.9 million for 2022. The 33% growth versus the same period in 2022 is primarily attributed to strong commercial sales of WAKIX driven by continued organic demand tapping into a large market opportunity. GAAP net income for the year ended December 31, 2023, was $128.9 million, or $2.13 per diluted share, compared to GAAP net income of $181.5 million, or $2.97 per diluted share, for 2022. The decrease in GAAP net income was primarily driven by the release of the valuation allowance on our deferred tax assets, which resulted in a $74.5 million income tax benefit for the year ended December 31, 2022. Non-GAAP adjusted net income was $188.4 million, or $3.12 per diluted share, for the year ended December 31, 2023, compared to Non-GAAP adjusted net income of $183.5 million, or $3.00 per diluted share, for 2022.

Non-GAAP Financial MeasuresIn addition to our GAAP results, we present certain Non-GAAP metrics 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 for 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. About WAKIX® (pitolisant) TabletsWAKIX, a first-in-class medication, is approved by the U.S. Food and Drug Administration for the treatment of excessive daytime sleepiness or cataplexy in adult patients with narcolepsy and has been commercially available in the U.S. since Q4 2019. 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 (H₃) receptor antagonist/inverse agonist. The mechanism of action of WAKIX is unclear; however, its efficacy could be mediated through its activity at H₃ 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. Indications and UsageWAKIX is indicated for the treatment of excessive daytime sleepiness or cataplexy in adult patients with narcolepsy. Important Safety Information ContraindicationsWAKIX 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. Warnings and PrecautionsWAKIX 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. The risk of QT prolongation may be greater in patients with hepatic or renal impairment due to higher concentrations of pitolisant; monitor these patients for increased QTc. Dosage modification is recommended in patients with moderate hepatic impairment and moderate or severe renal impairment (see full prescribing information). WAKIX is not recommended in patients with end-stage renal disease (ESRD). Adverse ReactionsIn the placebo-controlled clinical trials conducted in patients with narcolepsy with or without cataplexy, the most common adverse reactions (≥5% and twice placebo) for WAKIX were insomnia (6%), nausea (6%), and anxiety (5%). Other adverse reactions that occurred at ≥2% and more frequently than in patients treated with placebo included headache, upper respiratory infection, musculoskeletal pain, heart rate increased, hallucinations, irritability, abdominal pain, sleep disturbance, decreased appetite, cataplexy, dry mouth, and rash. Drug InteractionsConcomitant administration of WAKIX with strong CYP2D6 inhibitors increases pitolisant exposure by 2.2-fold. Reduce the dose of WAKIX by half. Concomitant use of WAKIX with strong CYP3A4 inducers decreases exposure of pitolisant by 50%. Dosage adjustments may be required (see full prescribing information). H1 receptor antagonists that cross the blood-brain barrier may reduce the effectiveness of WAKIX. Patients should avoid centrally acting H1 receptor antagonists. WAKIX is a borderline/weak inducer of CYP3A4. Therefore, reduced effectiveness of sensitive CYP3A4 substrates may occur when used concomitantly with WAKIX. The effectiveness of hormonal contraceptives may be reduced when used with WAKIX and effectiveness may be reduced for 21 days after discontinuation of therapy. Use in Specific PopulationsWAKIX may reduce the effectiveness of 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. 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. The safety and effectiveness of WAKIX have not been established in patients less than 18 years of age. WAKIX 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. WAKIX is not recommended in patients with end-stage renal disease. Dosage adjustment of WAKIX is recommended in patients with moderate or severe renal impairment. Dosage reduction is recommended in patients known to be poor CYP2D6 metabolizers; these patients have higher concentrations of WAKIX than normal CYP2D6 metabolizers. Please see the Full Prescribing Information for WAKIX for more information. To 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. About NarcolepsyNarcolepsy 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 – its two cardinal symptoms – 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. About Idiopathic HypersomniaIdiopathic 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. About Prader-Willi SyndromePWS is an orphan/rare, genetic neurological disorder with many of the symptoms resulting from hypothalamic dysfunction. The hypothalamus is the part of the brain that controls both sleep-wake state stability and signals that mediate the balance between hunger and satiety, resulting in two of the main symptoms in patients with PWS; EDS and hyperphagia (an intense persistent sensation of hunger accompanied by food preoccupations, an extreme drive to consume food, food-related behavior problems, and a lack of normal satiety). Other features include low muscle tone, short stature, behavioral problems, and cognitive impairment. Approximately 15,000 to 20,000 people in the U.S. live with PWS, and over half of them experience EDS and the majority of them have behavioral disturbances. About Myotonic Dystrophy Type 1 Myotonic dystrophy Type 1 (DM1) is the most common form of adult-onset muscular dystrophy. It is a genetic disorder inherited in an autosomal-dominant pattern. Latest estimates suggest a prevalence of about one per 2,100 people with the genetic defect for DM1. This equates to about 150,000 people in the U.S. with the genetic defect for DM1. Estimates suggest there are 40,000 people currently diagnosed with DM1 in the U.S., with up to 90% of them reporting EDS and fatigue and over 60% of them experiencing cognitive dysfunction. About Fragile X SyndromeFragile X syndrome (FXS) is a rare genetic disorder that is the leading known cause of both inherited intellectual disability and autism spectrum disorder. The disorder negatively affects synaptic function, plasticity and neuronal connections, and results in a spectrum of intellectual disabilities and behavioral symptoms, such as social avoidance and irritability. While the exact prevalence is unknown, upwards of 80,000 patients in the U.S. and 121,000 patients in the European Union and the UK are believed to have FXS, based on FXS prevalence estimates of approximately 1 in 4,000 to 7,000 in males and approximately 1 in 8,000 to 11,000 in females. There is a significant unmet medical need in patients living with FXS as there are currently no FDA approved treatments for this disorder. FXS is caused by a mutation in FMR1, a gene which modulates a number of systems, including the endocannabinoid system, and most critically, codes for a protein called FMRP. The FMR1 mutation manifests as multiple repeats of a DNA segment, known as the CGG triplet repeat, resulting in deficiency or lack of FMRP. FMRP helps regulate the production of other proteins and plays a role in the development of synapses, which are critical for relaying nerve impulses, and in regulating synaptic plasticity. In people with full mutation of the FMR1 gene, the CGG segment is repeated more than 200 times, and in most cases causes the gene to not function. Methylation of the FMR1 gene also plays a role in determining functionality of the gene. In approximately 60% of patients with FXS, who have complete methylation of the FMR1 gene, no FMRP is produced, resulting in dysregulation of the systems modulated by FMRP. About ZYN002ZYN002 is the first-and-only pharmaceutically manufactured synthetic cannabidiol devoid of THC and formulated as a patent-protected permeation-enhanced gel for transdermal delivery through the skin and into the circulatory system. The product is manufactured through a synthetic process in a cGMP facility and is not extracted from the cannabis plant. ZYN002 does not contain THC, the compound that causes the euphoric effect of cannabis, and has the potential to be a nonscheduled product if approved. Cannabidiol, the active ingredient in ZYN002, has been granted orphan drug designation by the United States Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of FXS and for the treatment of 22q. Additionally, ZYN002 has received FDA Fast Track designation for the treatment of behavioral symptoms in patients with FXS. About HBS-102HBS-102, an investigational compound, is a melanin-concentrating hormone (MCH) receptor 1 (MCHR1) antagonist that targets MCH neurons in the brain. It has the potential to be a first-in-class molecule with a novel mechanism of action that could offer a new approach to the treatment of a variety of rare neurological diseases.

About WAKIX® (pitolisant) Tablets WAKIX, a first-in-class medication, is approved by the U.S. Food and Drug Administration for the treatment of excessive daytime sleepiness or cataplexy in adult patients with narcolepsy and has been commercially available in the U.S. since Q4 2019. 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 (H₃) receptor antagonist/inverse agonist. The mechanism of action of WAKIX is unclear; however, its efficacy could be mediated through its activity at H₃ 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. Indications and Usage WAKIX is indicated for the treatment of excessive daytime sleepiness or cataplexy in adult patients with narcolepsy. Important Safety Information Contraindications 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. Warnings and Precautions 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. The risk of QT prolongation may be greater in patients with hepatic or renal impairment due to higher concentrations of pitolisant; monitor these patients for increased QTc. Dosage modification is recommended in patients with moderate hepatic impairment and moderate or severe renal impairment (see full prescribing information). WAKIX is not recommended in patients with end-stage renal disease (ESRD). Adverse Reactions In the placebo-controlled clinical trials conducted in patients with narcolepsy with or without cataplexy, the most common adverse reactions (≥5% and at least twice placebo) for WAKIX were insomnia (6%), nausea (6%), and anxiety (5%). Other adverse reactions that occurred at ≥2% 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. Drug Interactions Concomitant administration of WAKIX with strong CYP2D6 inhibitors increases pitolisant exposure by 2.2-fold. Reduce the dose of WAKIX by half. Concomitant use of WAKIX with strong CYP3A4 inducers decreases exposure of pitolisant by 50%. Dosage adjustments may be required (see full prescribing information). H1 receptor antagonists that cross the blood-brain barrier may reduce the effectiveness of WAKIX. Patients should avoid centrally acting H1 receptor antagonists. WAKIX is a borderline/weak inducer of CYP3A4. Therefore, reduced effectiveness of sensitive CYP3A4 substrates may occur when used concomitantly with WAKIX. The effectiveness of hormonal contraceptives may be reduced when used with WAKIX and effectiveness may be reduced for 21 days after discontinuation of therapy. Use in Specific Populations WAKIX may reduce the effectiveness of 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. 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. The safety and effectiveness of WAKIX have not been established in patients less than 18 years of age. WAKIX 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. WAKIX is not recommended in patients with end-stage renal disease. Dosage adjustment of WAKIX is recommended in patients with moderate or severe renal impairment. Dosage reduction is recommended in patients known to be poor CYP2D6 metabolizers; these patients have higher concentrations of WAKIX than normal CYP2D6 metabolizers.

Clinically meaningful improvements demonstrated in excessive daytime sleepiness and fatigue [07-December-2023] PLYMOUTH MEETING, Pa., Dec. 7, 2023 /PRNewswire/ -- Harmony Biosciences Holdings, Inc. ("Harmony" or the "Company") (Nasdaq: HRMY) today announced positive topline results from its Phase 2 signal detection study evaluating the safety and efficacy of pitolisant in adult patients with myotonic dystrophy type 1 (DM1). A clinically meaningful improvement was demonstrated on the primary efficacy endpoint, the change from baseline to the end of the double-blind period for excessive daytime sleepiness (EDS) as measured by the Daytime Sleepiness Scale (DSS). A clinically meaningful improvement was also demonstrated for fatigue, a secondary efficacy endpoint measured by the Fatigue Severity Scale (FSS). EDS and fatigue occur in up to 80-90% of patients with DM1 and impact daily functioning as much as muscular symptoms (myotonia and muscle weakness). "These strong topline results add to the body of evidence supporting the effectiveness of pitolisant for improving EDS," said Jeffrey M. Dayno, M.D., President and CEO of Harmony Biosciences. "In addition, a positive signal for pitolisant has been demonstrated for fatigue, suggesting it could be a potential new treatment option for this symptom as well. We are encouraged by these results, which underscore our commitment to translating innovative science into therapeutic possibilities for patients living with unmet medical needs." Topline results include: Clinically meaningful improvements were demonstrated in EDS as measured by DSS, Epworth Sleepiness Scale (ESS), and Clinical Global Impression of Severity (CGI-S) of EDS. On DSS, the mean change from baseline to end of double-blind period was -2.5 and -1.0 for the higher dose and lower dose pitolisant treatment groups, respectively, compared to -0.2 for placebo. On ESS, the mean change from baseline to end of double-blind period was -4.88 for the higher dose pitolisant treatment group compared to -0.10 for placebo. On CGI-S, the mean change from baseline to end of double-blind period was -0.9 for the higher dose pitolisant treatment group compared to -0.1 for placebo. Clinically meaningful improvements were demonstrated for fatigue as measured by the Fatigue Severity Scale (FSS). On FSS, the mean change from baseline to end of double-blind period was -0.86 and -0.36 for the higher dose and lower dose pitolisant treatment groups, respectively, compared to -0.13 for placebo. A clear and consistent dose-response was demonstrated with the higher dose pitolisant group showing a greater response than the lower dose group across the study endpoints. Safety and tolerability pro adult patients with DM1 was consistent with the established safety pro pitolisant with no new safety signals detected and no serious adverse events reported. "EDS is the most common non-muscular complaint in patients living with DM1, being present in the majority of patients," said Dr. Jean-Denis Brisson, Centre Intégré Universitaire De Santé Et De Services Sociaux du Saguenay-Lac-Saint-Jean. "The positive signals from this Phase 2 study are very encouraging, and support pitolisant as a potential treatment option for DM1." This Phase 2 signal detection study was a randomized, double-blind, placebo-controlled study in adults ages 18-65 with DM1. This study was not powered to demonstrate statistical significance. Thirty patients were randomized at baseline to receive lower dose pitolisant, higher dose pitolisant, or placebo in a 1:1:1 treatment ratio titrated over three weeks, followed by eight weeks of stable dosing. "These positive signals for pitolisant are promising news for the DM1 patient community, where 80-90 percent of the approximately 40,000 diagnosed DM1 patients in the U.S. experience significant EDS and fatigue with no FDA-approved treatments available," said Kumar Budur, M.D., M.S., Chief Medical Officer at Harmony Biosciences. "The strong signals for pitolisant reinforce our confidence in it as a potential treatment option worthy of further study in patients with DM1." The full dataset from this trial will include findings from other secondary outcomes, including the Myotonic Dystrophy Health Index (MDHI), cognitive functions, and the safety and effectiveness of pitolisant from the ongoing Open-Label Extension (OLE) Phase. Additional results from the trial will be shared early next year. Detailed results will be presented at an upcoming medical meeting and will be submitted for publication. Pitolisant is marketed as WAKIX® in the U.S. and is FDA approved to treat excessive daytime sleepiness or cataplexy in adults with narcolepsy. Pitolisant is not approved for use in patients with DM1 and is currently being evaluated as an investigational agent in this patient population. About Myotonic Dystrophy Type 1 Myotonic dystrophy Type 1 (DM1) is the most common form of adult-onset muscular dystrophy. It is a genetic disorder inherited in an autosomal-dominant pattern. Latest estimates suggest a prevalence of about one per 2,100 people with the genetic defect for DM1. This equates to about 150,000 people in the U.S. with the genetic defect for DM1. Estimates suggest there are 40,000 people currently diagnosed with DM1 in the U.S., with up to 90% of them reporting EDS and fatigue and over 60% of them experiencing cognitive dysfunction.
