24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Recent fundamentally positive company news (profitability, launch progress) saw negative price reactions, while litigation headlines produced mixed moves. Today’s acquisition news follows a stretch of volatility around legal and governance developments.
Over the last several months, Soleno transitioned into a commercial-stage company with VYKAT XR, reporting $91.7M Q4 and $190.4M full-year 2025 product revenue and turning to $20.9M net income. Despite this, shares fell after earnings and the CFO transition in late February. March brought governance updates, insider-selling-related Form 4s, and litigation-focused headlines with modest to negative moves. Against this backdrop, Neurocrine’s all-cash acquisition agreement marks a strategic outcome for the VYKAT XR franchise after its first profitable year.

Strategic Rationale and Financial Benefits of the Transaction
The transaction is expected to:
- Strengthen Neurocrine's Leadership in Endocrinology and Rare Disease, and Advance a Diversified Portfolio of First-in-Class Medicines: Following the completion of the transaction, Neurocrine will have three marketed, first-in-class therapies: INGREZZA®, the vesicular monoamine transmitter 2 (VMAT2) market leader for the treatment of tardive dyskinesia and the chorea associated with Huntington's disease, with
$2.51 billion $301 million $190 million - Add a First-in-Class Therapy with Durable Value Creation: VYKAT XR is the first and only FDA‑approved therapy for hyperphagia with PWS in
the United States . Following a successful launch in 2025, VYKAT XR is well positioned as the foundational first-line therapy for PWS and is supported by a strong intellectual property estate that is expected to extend into the mid-2040s, providing a durable platform for long‑term value creation. - Provide a Transformative Therapy Aligned with Neurocrine's Strategic Focus.

About PWS
Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder caused by an abnormality in the gene expression on chromosome 15. The Prader-Willi Syndrome Association USA estimates that PWS occurs in one in every 15,000 live births. The defining symptom of PWS is hyperphagia, a chronic and life-threatening condition characterized by an intense persistent sensation of hunger accompanied by food preoccupations, an extreme drive to consume food, food-related behavior problems, and a lack of normal satiety, which can severely diminish the quality of life for individuals with PWS and their families. Hyperphagia can lead to significant mortality (e.g., stomach rupture, choking, accidental death due to food-seeking behavior) and longer term, co-morbidities such as diabetes, obesity, and cardiovascular disease.
INDICATION
VYKAT XR (diazoxide choline) extended-release tablets is indicated for the treatment of hyperphagia in adults and pediatric patients 4 years of age and older with Prader-Willi syndrome (PWS).
IMPORTANT SAFETY INFORMATION
Contraindications
Use of VYKAT XR is contraindicated in patients who have a known hypersensitivity to diazoxide, other components of VYKAT XR, or to thiazides.
Warnings and Precautions
Hyperglycemia
Hyperglycemia, including diabetic ketoacidosis, has been reported. Before initiating VYKAT XR, test fasting plasma glucose (FPG) and HbA1c; optimize blood glucose in patients who have hyperglycemia. During treatment, regularly monitor fasting glucose (FPG or fasting blood glucose) and HbA1c. Monitor fasting glucose more frequently during the first few weeks of treatment in patients with risk factors for hyperglycemia.
Risk of Fluid Overload
Edema, including severe reactions associated with fluid overload, has been reported. Monitor for signs or symptoms of edema or fluid overload. VYKAT XR has not been studied in patients with compromised cardiac reserve and should be used with caution in these patients.
