Neurocrine to Acquire Soleno Therapeutics for $2.9B, Expanding Rare Disease Portfolio

Neurocrine Biosciences has agreed to acquire Soleno Therapeutics in a $2.9 billion all-cash transaction, reinforcing its strategic expansion into endocrinology and rare disease treatments.

Under the terms of the agreement, Neurocrine will pay $53 per share — representing a premium of approximately 34% over Soleno’s recent closing price.

Strategic Move Into Rare Disease and Metabolic Therapies

The acquisition centers on Soleno’s lead therapy, Vykat XR, a treatment for Prader-Willi syndrome — a rare condition characterized by chronic and compulsive hunger.

According to The Wall Street Journal, the drug generated approximately $190 million in revenue in its first year following approval, underscoring strong early commercial traction in a niche but high-value market.

Commercial Expansion and Long-Term Value

The deal is expected to strengthen Neurocrine’s commercial portfolio and provide access to a differentiated, first-in-class therapy with long-term growth potential. Vykat XR is also supported by intellectual property protections extending into the mid-2040s, reinforcing its durability as a revenue-generating asset.

Neurocrine plans to fund the transaction primarily through cash on hand, complemented by a modest level of debt, with completion anticipated in the coming months.

Biotech M&A Momentum Accelerates

The transaction reflects a broader acceleration in biotechnology dealmaking, as companies increasingly target rare disease platforms with proven therapies and scalable pipelines.

As reported by The Wall Street Journal, the acquisition aligns with a surge in sector activity, with tens of billions of dollars in biotech deals already recorded in early 2026.
