THOMSON REUTERS ANNOUNCES ANNUAL RENEWAL OF NORMAL COURSE ISSUER BID

Thomson Reuters Corp. has received approval from the Toronto Stock Exchange (TSX) for the annual renewal of its normal course issuer bid (NCIB).

Under the NCIB, up to 15 million common shares (representing less than 2 per cent of the total outstanding shares) may be repurchased in open market transactions on the TSX or the New York Stock Exchange between May 22, 2012, and May 21, 2013. In accordance with TSX rules, any daily repurchases would be limited to a maximum of 315,657 shares, which represents 25 per cent of the average daily trading volume on the TSX for the six months ended April 30, 2012 (other than pursuant to a block purchase exception). On May 8, 2012, there were 828,646,016 Thomson Reuters common shares outstanding. Any shares that are repurchased will be cancelled. Decisions regarding any future repurchases will be based on market conditions, share price and other factors, including opportunities to invest capital for growth. Under its NCIB that began on May 13, 2011, and expired on May 12, 2012, Thomson Reuters repurchased 12,372,300 common shares for a total cost of $372.3-million (U.S.), representing an average price of $30.09 (U.S.) per share.

From time to time, when Thomson Reuters does not possess material non-public 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.

We seek Safe Harbor.
