GSK plc simplifies ViiV Healthcare ownership as Pfizer exits and Shionogi raises stake
GSK plc wrapped up changes to ViiV Healthcare’s ownership structure on April 1. After Pfizer’s exit from the HIV-focused joint venture, Japan’s Shionogi bumped its stake up to 21.7%. GSK remains the majority owner with 78.3%, the company said. Timing is crucial here: ViiV is a core growth driver as GSK shifts focus toward specialty medicines. For 2025, GSK reported an 11% increase in HIV sales to 7.7 billion pounds, fueling a 17% jump in specialty medicines revenue.
