GSK plc: Rebuilt Biopharma, Racing the Patent Cliff

GSK plc is a UK biopharma rebuilt around vaccines and specialty medicines after the 2022 Haleon demerger, with 2025 sales of £32.7bn anchored by Shingrix and the ViiV HIV franchise. Specialty medicines now drive growth (£13.5bn, +14% CER in Q1 2026) and core operating profit rose 11% to £9.8bn, yet the whole story hinges on replacing the dolutegravir HIV cliff in 2028–2030 before it arrives. Rating Hold: a genuinely higher-quality franchise at roughly 11.6x core earnings, but the price already assumes much of the patent-cliff bridge, leaving little margin of safety.
