Correction - TR-1 Notification of Major Holdings

On 14 May 2026, PureTech Health plc ("PureTech" or the "Company"), was notified by Citigroup Inc. that the TR-1 notification it submitted to the Company on 7 May 2026, and which was subsequently announced by the Company on 7 May 2026 under RNS number 5007D, was provided in error.

Accordingly, shareholders should disregard the TR-1 notification announced by the Company on 7 May 2026 and instead refer to the TR-1 notification in relation to Citigroup Inc. announced by the Company on 27 April 2026, which is available under RNS number 1025C.
