GSK, Pfizer and Shionogi complete changes to ViiV Healthcare shareholding

·   Completion of Pfizer's exit of its investment in ViiV Healthcare

·   Increase of Shionogi's holding to 21.7%, with GSK maintaining 78.3% majority share

 

GSK plc (LSE/NYSE: GSK) ("GSK"), and Shionogi & Co., Ltd (Head Office: Osaka, Japan; Chief Executive Officer: Isao Teshirogi, Ph.D) ("Shionogi"), further to their announcements on 20 January 2026, announce the completion of the transaction for the 11.7% economic interest in ViiV Healthcare Limited ("ViiV Healthcare") previously held by Pfizer Inc. (NYSE: PFE) ("Pfizer") to be replaced with an investment by Shionogi. As a result of this transaction, Shionogi has increased its economic interest in ViiV Healthcare to 21.7%. GSK maintains its 78.3% majority owned economic interest.

ViiV Healthcare issued new shares to Shionogi for consideration of $2.125 bn and cancelled Pfizer's holding in ViiV Healthcare. Pfizer received $1.875 bn and GSK received a special dividend of $0.250 bn (paid in GBP).

Financial Considerations

The Pfizer put option liability shown in GSK's accounts for the year ended 31 December 2025 was extinguished through retained earnings at completion. The put option liability was remeasured immediately prior to completion on the same methodology as at 31 December 2025, with the fair value change in the liability recognised as an adjusting item through other operating income.
