StockStory’s Take

Supernus Pharmaceuticals reported Q3 results that were above Wall Street’s revenue and profit expectations, but the market reacted negatively, reflecting concerns over execution challenges and forward guidance. Management attributed quarterly growth to robust demand for Qelbree and GOCOVRI, as well as initial contributions from Onapgo and collaboration revenue from Zurzuvae. CEO Jack Khattar acknowledged that supply constraints for Onapgo limited the company’s ability to fully meet patient demand, describing the issue as a “high-quality problem” but one that requires urgent resolution. Management also cited higher operating expenses related to the Sage acquisition as a key factor weighing on profitability.

Looking forward, Supernus’ updated full-year guidance reflects expectations for continued momentum from its four key growth products, though supply issues with Onapgo and integration expenses from recent acquisitions may impact near-term results. CEO Jack Khattar signaled that resolving Onapgo’s capacity bottleneck is a top priority, noting, “We’re working around the clock literally with our suppliers trying to line up more batches, line up more deliveries.” The company’s outlook also depends on successful integration of the Sage business, continued expansion in women’s health, and advancing its pipeline programs in central nervous system disorders.

Key Insights from Management’s Remarks

Management identified strong sales of Qelbree, GOCOVRI, and Zurzuvae as key drivers, while Onapgo’s early success was tempered by supply limitations and one-off acquisition costs.

• Qelbree growth sustained: Qelbree delivered 23% prescription growth and 31% net sales growth year-over-year, supported by strength in both pediatric and adult ADHD segments.
• Onapgo launch constrained by supply: Onapgo’s initial demand outpaced supply, with cartridge filling limitations slowing new patient starts. Management is prioritizing inventory for existing patients while seeking to resolve the bottleneck.
• Zurzuvae collaboration revenue boost: The integration of Sage and the addition of Zurzuvae contributed meaningfully to collaboration revenues. Management expects up to $200 million in annual synergies by mid-2026.
• GOCOVRI momentum continues: GOCOVRI posted 15% net sales growth, attributed to increasing prescriptions and a broader prescriber base in movement disorders.
• Acquisition costs weigh on margins: The quarter’s operating margin was significantly impacted by $70 million in Sage-related acquisition costs and higher intangible asset amortization, leading to a GAAP operating loss despite underlying product growth.

Drivers of Future Performance

Management’s outlook centers on resolving Onapgo supply constraints, maximizing growth from core products, and disciplined expense control amid ongoing integration activities.

• Onapgo supply resolution critical: Restoring full availability of Onapgo is seen as essential for sustaining momentum and recapturing patients who may have turned to alternatives during the supply shortage. Management emphasized that capacity improvements are underway, but timing remains uncertain.
• Pipeline and market expansion: Supernus is advancing new development programs, including planned trials for SPN-443 in ADHD and SPN-820 in major depressive disorder. The company also aims to leverage its infrastructure to pursue deals in women’s health and rare CNS disorders.
• Expense discipline post-acquisition: With integration of Sage nearing completion, management expects non-GAAP operating earnings to improve as one-time acquisition costs subside. However, ongoing R&D and SG&A investments are likely to keep reported margins under pressure in the near term.

Catalysts in Upcoming Quarters

In coming quarters, the StockStory team will closely monitor (1) progress in resolving Onapgo’s supply chain bottleneck and its impact on patient retention, (2) the pace of integration and realized synergies from the Sage acquisition, and (3) continued prescription growth for Qelbree and GOCOVRI. Advancements in pipeline programs and potential business development activity in women’s health or rare CNS disorders will also be important milestones.
