Management Comments

• "The approximately 80,000 U.S. families in the Fragile X community have been waiting far too long for a treatment that addresses the core symptoms of this serious condition. We are on track to announce the Phase 3 readout for ZYN002 in the third quarter, which represents a potentially transformative moment for these patients and for Harmony. With global rights to this product, if successful, we see a meaningful opportunity to address this significant unmet medical need both in the U.S. and around the world."
• "Based on the strength of our commercial business, our continued profitability and commitment to patients, Harmony is building a commercially durable business with a robust pipeline and clear path to delivering long-term value for patients, providers, and shareholders alike."

Industry Context

Harmony Biosciences operates in the specialized and high-growth rare neurological disease market, focusing on areas with significant unmet medical needs such as narcolepsy, Fragile X Syndrome, and various epileptic encephalopathies. The strong performance of WAKIX, a first-in-class medication, positions the company as a leader in the sleep/wake disorder segment, particularly as it approaches blockbuster status. The strategic expansion into Fragile X Syndrome with ZYN002 and rare epilepsies with EPX-100 and EPX-200 aligns with the broader industry trend of targeting orphan diseases, which often benefit from expedited regulatory pathways and premium pricing due to high unmet needs. The company's focus on developing next-generation formulations of pitolisant and novel mechanisms like orexin-2 agonists and regenerative cellular therapies reflects the industry's drive for innovation and differentiated products to maintain competitive advantage against potential generic entries and emerging therapies.

Comparison to Industry Standards

• The company's 16% year-over-year revenue growth for WAKIX in its sixth year on the market is strong, indicating sustained demand and effective commercialization, which compares favorably to many pharmaceutical products that typically see growth deceleration post-launch.
• Achieving over $672 million in cash and investments positions Harmony Biosciences as a self-funding biotech, a unique and strong financial profile compared to many smaller biotech companies that frequently rely on external capital raises to fund their extensive R&D pipelines.
• The advancement of four ongoing Phase 3 registrational trials, with plans for up to six by year-end, demonstrates a robust and active late-stage pipeline, which is competitive with larger pharmaceutical companies and indicative of significant future growth potential in rare disease markets.
• The patent settlement for WAKIX extending exclusivity until at least January 2030 (or July 2030 with pediatric exclusivity) provides a clear runway for continued revenue generation, a critical factor for specialty pharmaceutical companies facing generic competition.

Legal Proceedings

• The company announced a settlement agreement with Lupin Limited, resolving patent infringement litigation related to Lupin's Abbreviated New Drug Application (ANDA) for a generic version of WAKIX. Lupin received a license to launch its generic product no earlier than January 2030 (or July 2030 with pediatric exclusivity).
• The company continues to litigate its consolidated patent infringement case against several other companies that have filed ANDAs seeking approval for generic versions of WAKIX (pitolisant hydrochloride).
