THOMSON REUTERS ANNOUNCES $1.0 BILLION SHARE REPURCHASE PROGRAM

Thomson Reuters Corp. plans to repurchase up to $1.0-billion of its shares. Purchases of shares will occur under a new normal course issuer bid (NCIB) that has been approved by the Toronto Stock Exchange (TSX).

Under the new NCIB, up to 10 million common shares (which represents approximately 2.22 per cent of the company's issued and outstanding common shares as of Aug. 12, 2025) may be repurchased between Aug. 19, 2025, and Aug. 18, 2026.

Under the NCIB, shares may be repurchased in open market transactions on the TSX, the Nasdaq Global Select Market (Nasdaq), and/or other exchanges and alternative trading systems, if eligible, or by such other means as may be permitted by the TSX and/or Nasdaq or under applicable law, including private agreement purchases or share purchase program agreement purchases if Thomson Reuters receives, if applicable, an issuer bid exemption order in the future from applicable securities regulatory authorities in Canada for such purchases. The price that Thomson Reuters will pay for common shares in open market transactions will be the market price at the time of purchase or such other price as may be permitted by the TSX. Any private agreement purchases made under an exemption order, if applicable, may be at a discount to the prevailing market price. In accordance with TSX rules, any daily repurchases (other than pursuant to a block purchase exception) on the TSX under the renewed NCIB are limited to a maximum of 91,026 shares, which represents 25 per cent of the average daily trading volume on the TSX of 364,105 for the six months ended July 31, 2025. Any shares that are repurchased are cancelled.

From time to time when Thomson Reuters does not possess material nonpublic information about itself or its securities, it may enter into a predefined plan with its broker to allow for the repurchase of shares at times when Thomson Reuters ordinarily would not be active in the market due to its own internal trading blackout periods, insider trading rules or otherwise. Any such plans entered into with Thomson Reuters' broker will be adopted in accordance with applicable Canadian securities laws and the requirements of Rule 10b5-1 under the U.S. Securities Exchange Act of 1934, as amended.

Thomson Reuters has historically maintained a disciplined capital strategy that balances growth, long-term financial leverage, credit ratings and returns to shareholders through dividends and share repurchases. The NCIB provides the company with a flexible way to provide returns to shareholders who choose to participate by selling their shares.

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.
