Thomson Reuters Announces Final Results of Exchange Offers and Consent Solicitations

and Intention to File Replacement Base Shelf Prospectus

TORONTO, March 17, 2025 – Thomson Reuters (TSX/Nasdaq: TRI), a global content and technology company, announced today the expiry of its previously announced offers to exchange, and related consent solicitations of, certain series of notes (“Old Notes”) of Thomson Reuters Corporation, an Ontario corporation (“TRC”), for new notes (“New Notes”) to be issued by TR Finance LLC (“TR Finance”), an indirect 100% owned U.S. subsidiary of TRC, at 5:00 p.m., New York City time, on March 17, 2025 (the “Expiration Time”). As of the Expiration Time, the aggregate principal amounts of each series of Old Notes listed in the table below had been validly tendered (and not validly withdrawn) for exchange.

As announced on February 11, 2025, TRC is making the exchange offers to optimize the Thomson Reuters group capital structure and align revenue generation to indebtedness and give existing holders of Old Notes the option to receive notes issued by TR Finance with the same financial terms and substantially similar covenants as the applicable series of Old Notes. Thomson Reuters expects the settlement date of the exchange offers to be on or about March 20, 2025.
