SHARE BUYBACK MANAGEMENT

3 August 2026

International Public Partnerships Limited ('INPP', or the 'Company') notes that it is about to enter a closed period ahead of the notification of its half-year results for the six months to 30 June 2026 (the 'HY26 Closed Period').

The Company has previously appointed Deutsche Numis to manage an irrevocable, non-discretionary share buyback programme to continue the Company's buybacks of its ordinary shares in the market (the 'Irrevocable') during closed periods. The Irrevocable instructs Deutsche Numis to operate these buybacks automatically during the respective closed periods.

The Company's existing share buyback programme of up to £225 million, is expected to run until the end of March 2027. At the time of writing, c.£150 million of shares have been bought by the Company.

Details of the half-year results publications will follow shortly.

ENDS.
