“Soleno Therapeutics (NASDAQ: SLNO) achieved a significant profitability milestone in 2025, posting full-year net income of $20.9 million driven by strong U.S. sales of its rare disease therapy VYKAT XR, just nine months after launch. Concurrently, the company announced the retirement of longtime CFO James Mackaness and the appointment of Jennifer Fulk as his successor, prompting investor scrutiny over leadership continuity, execution risks in a niche market, and whether the rapid shift to profitability justifies the stock’s elevated valuation multiples amid ongoing commercialization challenges.”
Soleno Therapeutics Achieves Profitability Milestone Amid CFO Transition
Soleno Therapeutics has marked a pivotal turn in its evolution from a development-stage biotech to a commercial player with the achievement of full-year profitability in 2025. The company’s flagship product, VYKAT XR (diazoxide choline) extended-release tablets, approved for treating hyperphagia in Prader-Willi syndrome (PWS), generated net revenue of $190.4 million for the year. This figure reflects less than nine months of commercial availability following the product’s U.S. launch, underscoring rapid market uptake in a patient population estimated at around 10,000 in the United States.
In the fourth quarter alone, net revenue reached $91.7 million, contributing to a quarterly net income of approximately $43.4 million, or $0.82 per basic share. For the full year, net income stood at $20.9 million, or $0.40 per basic share, a stark contrast to the $175.9 million net loss reported in 2024. This swing to profitability was supported by $48.7 million in cash flow from operating activities in the fourth quarter, highlighting operational efficiency as sales ramped up.
The company ended 2025 with a robust cash position of $506.1 million in cash, cash equivalents, and marketable securities, even after executing a $100 million accelerated share repurchase program in November. This liquidity provides a strong foundation for continued commercial efforts, potential international expansions, and pipeline advancements.
However, the profitability achievement has not come without questions, particularly as it coincides with a key executive transition. Soleno announced the planned retirement of Chief Financial Officer James Mackaness by the end of the first quarter of 2026, with Jennifer Fulk stepping in as successor effective early March. Mackaness, who has guided the company’s finances through its transition to commercialization, will remain as a consultant through the end of the year to facilitate a smooth handover.
Fulk brings extensive experience from more than two decades in public company finance, including 15 years at Eli Lilly in senior roles such as CFO for U.S. Bio-Medicines and Vice President of Investor Relations. Her background in large pharmaceutical operations and recent leadership in smaller entities positions her well for Soleno’s next phase, but the timing of the change—at a moment of demonstrated commercial success—has sparked debate among investors about potential disruptions in financial strategy, reporting, and capital allocation.
The leadership shift arrives as Soleno navigates the realities of sustaining momentum in a specialized rare disease market. VYKAT XR has achieved broad payer coverage, with over 185 million lives covered, and the company is targeting approximately 1,000 additional patient start forms in the coming 9 to 12 months to maintain growth. Yet, the niche nature of PWS hyperphagia treatment introduces execution risks, including physician adoption, patient persistence, and competition from off-label or emerging therapies.
Valuation considerations loom large in this context. With trailing twelve-month revenue at $190.4 million and net income around $20.5 million to $20.9 million, the stock trades at a premium multiple reflective of high growth expectations. Analysts have pointed to forward earnings forecasts suggesting continued expansion, but the rapid profitability ramp—fueled by a single product—raises questions about sustainability and margin durability. One-time items, such as a $5.5 million adjustment in contingent consideration liabilities related to prior acquisitions, also factor into earnings quality assessments.
Key Financial Highlights from 2025

Soleno’s path forward hinges on maintaining commercial traction while integrating new leadership. The profitability milestone validates the commercial model in a high-unmet-need rare disease space, but the CFO transition adds a layer of uncertainty that could influence investor sentiment and valuation reassessments in the near term. As the company eyes regulatory progress in Europe and other territories, the focus remains on translating early success into long-term, consistent earnings power.
