KALV Stock Surges 38.6% on $1.9B Chiesi Acquisition Deal

KalVista Pharmaceuticals (KALV) stock exploded higher on April 29, 2026, after Italy’s Chiesi Group announced plans to acquire the Cambridge-based biotech company for approximately $1.9 billion in an all-cash transaction. KALV stock surged 38.6% to close at $26.67 per share on massive trading volume of 71.4 million shares, far exceeding the 50-day average of 1.16 million. The acquisition price of $27 per share represents a significant premium to recent trading levels. This deal marks a major milestone for KalVista, which specializes in small molecule protease inhibitors targeting rare diseases like hereditary angioedema (HAE) and diabetic macular edema (DME). The transaction is expected to close later this year, subject to customary closing conditions.

Why Chiesi Acquired KalVista

Chiesi Group, a privately held Italian pharmaceutical company, is expanding its rare disease portfolio through this strategic acquisition. KalVista’s lead programs align perfectly with Chiesi’s focus on specialty therapeutics. The company’s sebetralstat candidate is advancing through Phase 3 clinical trials (KONFIDENT program) as a potential oral, on-demand therapy for acute HAE attacks. KalVista also has KVD824 in development for chronic HAE management and KVD001, which completed Phase II trials for diabetic macular edema treatment.

The acquisition provides Chiesi with immediate access to KalVista’s clinical-stage assets and experienced management team led by CEO Benjamin L. Palleiko. This deal strengthens Chiesi’s position in the rare disease market, where unmet medical needs remain significant. The all-cash structure demonstrates Chiesi’s confidence in KalVista’s pipeline and commitment to completing the transaction without financing contingencies.
