On May 9, 2022, PureTech Health plc (LSE: PRTC, Nasdaq: PRTC) (the “Company”) announced the commencement of a $50 million share repurchase program (the “Program”) of its ordinary shares of one pence each (“Ordinary Shares”). The Company plans to execute the Program in two equal tranches, the first of which was completed on October 26, 2022. In respect of each of the two tranches, PureTech entered into an irrevocable non-discretionary instruction with Jefferies International Limited (“Jefferies”) in relation to the purchase by Jefferies of Ordinary Shares for an aggregate consideration (excluding expenses) of no greater than $25 million and the simultaneous on-sale of such Ordinary Shares by Jefferies to PureTech. Jefferies makes its trading decisions in relation to the Ordinary Shares independently of, and uninfluenced by, the Company. Purchases may continue during any close period to which the Company is subject. Any purchase of Ordinary Shares under the second tranche of the Program are carried out on the London Stock Exchange and any other UK recognized investment exchange which may be agreed, in accordance with pre-set parameters and in accordance with, and subject to limits, including those limits related to daily volume and price, prescribed by the Company’s general authority to repurchase Ordinary Shares granted by its shareholders at its most recent annual general meeting on June 15, 2022, Chapter 12 of the Financial Conduct Authority’s UK Listing Rules, Article 5(1) of Regulation (EU) No. 596/2014 (as incorporated into UK domestic law by the European Union (Withdrawal) Act 2018) and Commission Delegated Regulation (EU) 2016/1052 (as incorporated into UK domestic law by the European Union (Withdrawal) Act 2018). All Ordinary Shares repurchased under the Program will be held in treasury.

During the month ended May 31, 2023, the Company had the following daily purchases of its own Ordinary Shares under the Program through Jefferies:
