Seven questions, 60-second thesis frame.
What changed, and when
GSK plc announced on 09 Jun 2026 that it has agreed to acquire Nuvalent Inc. in an all‑cash transaction valued at $10.6 billion (GSK press release). Independent reports confirm the terms and strategic rationale (Reuters, The Guardian, LiveMint).
60-second thesis frame
The acquisition immediately strengthens GSK’s oncology portfolio with three targeted assets, including two late-stage NSCLC candidates: zidesamtinib (ROS1 inhibitor) and neladalkib (ALK inhibitor), both under FDA review with expected decisions in late 2026 (GSK press release). A third asset, NVL‑330, plus preclinical programmes, expand the R&D pipeline. The deal is structured as an all-cash tender offer at $124 per Nuvalent share, with closure expected in Q3 2026 pending regulatory and shareholder approvals (LiveMint). Financially, GSK expects the acquisition to be accretive to sales and core operating profit by 2027 and EPS by 2029 (GSK press release).
