THOMSON REUTERS ESTABLISHES AUTOMATIC SHARE PURCHASE PLAN

In connection with Thomson Reuters Corp.'s previously announced $1.0-billion share repurchase program and normal course issuer bid (NCIB) to purchase up to 10 million common shares between Aug. 19, 2025, and Aug. 18, 2026, it has entered into an automatic share purchase plan (ASPP) with its broker. The ASPP is intended to allow for the purchase of shares under the NCIB during predetermined times when the company would ordinarily not be permitted to purchase shares due to customary blackout periods or other regulatory restrictions.

Purchases under the ASPP will be made by the company's broker based upon parameters set by Thomson Reuters when it is not in possession of material non-public information relating to the company or the shares. The ASPP has been entered into in accordance with the requirements of the TSX and applicable Canadian securities laws and will terminate when the NCIB expires, unless terminated earlier in accordance with its terms. All purchases made under the ASPP will be included in computing the number of shares purchased under the NCIB. Outside of predetermined blackout periods, shares may be purchased under the NCIB based on management's discretion, in compliance with TSX rules and applicable securities laws.

Decisions regarding any future repurchases will depend on certain factors, such as market conditions, share price and other opportunities to invest capital for growth. Thomson Reuters may elect to suspend or discontinue share repurchases at any time, in accordance with applicable laws.
