Expected Drivers of Future Revenue Growth for Supernus Pharmaceuticals (SUPN)

• Continued Growth of Key Products: Supernus Pharmaceuticals anticipates ongoing revenue growth from its established key products, Qelbree and GOCOVRI. Qelbree, an ADHD medication, has demonstrated robust performance with significant increases in net sales and prescription growth year-over-year. Similarly, GOCOVRI, used for Parkinson's disease, continues to show strong net sales growth and an expanding prescriber base.
• Ramp-up and Supply Resolution for ONAPGO: The recently launched product, ONAPGO (for Parkinson's disease), has experienced strong initial demand that has exceeded expectations since its introduction in April 2025. While the company has faced temporary supply constraints, resolving these bottlenecks and increasing manufacturing capacity will be a significant driver of revenue growth as Supernus aims to meet the high patient demand.
• Collaboration Revenue from ZURZUVAE: The strategic acquisition of Sage Therapeutics, completed on July 31, 2025, has introduced ZURZUVAE into Supernus's product portfolio. This collaboration is already contributing substantial revenue, with U.S. sales of ZURZUVAE increasing significantly in Q3 2025 compared to the previous year. This expansion into women's health is expected to be a sustained revenue stream.
• Advancement and Launch of Pipeline Products: Supernus has a promising pipeline of product candidates that could fuel future revenue. SPN-830 (for Parkinson's disease) is awaiting FDA approval, with a target date in early 2025. Additionally, SPN-820 for treatment-resistant depression and SPN-817 for epilepsy have shown positive Phase 2a data, with plans for Phase 2b studies commencing by the end of 2024 or in 2025 and 2026. The progression and potential commercialization of these and other pipeline assets like SPN-443 (for ADHD) represent significant growth opportunities.
• Strategic Acquisitions and Market Expansion: Supernus Pharmaceuticals is actively pursuing strategic opportunities to strengthen its market position and diversify its portfolio. The company aims to leverage its existing infrastructure to explore deals in new therapeutic areas, such as women's health and rare central nervous system (CNS) disorders. This inorganic growth strategy, exemplified by the Sage acquisition, is expected to broaden its market reach and revenue base.
