  • Nuvalent Shares Surge Near $124 Following GSK's $10.6 Billion Buyout Offer
    June 9, 2026, 10:35 AM EDT. Nuvalent's stock jumped 38.9% to $122.93 after GSK announced a $10.6 billion cash acquisition at $124 per share, reflecting a 40% premium to the last close. The deal highlights GSK's strategic move to expand its oncology portfolio beyond its current 6% share of sales, aiming to capitalize on Nuvalent's two lung cancer drugs pending FDA decisions this year. The tender offer needs the approval of at least half of Nuvalent's Class A shares and U.S. antitrust clearance. Early analyst reactions included target price adjustments but echoed caution over valuation. Nuvalent's pipeline products could face competition from existing ALK-targeted therapies by Pfizer and Roche.
