NEWS RELEASE FOR IMMEDIATE RELEASE

Thomson Reuters Announces Proposed Unification of Dual Listed Company Structure

Shareholders to benefit from single consolidated pool of liquidity

NEW YORK, NY, June 22, 2009 – Thomson Reuters (NYSE: TRI; TSX: TRI; LSE: TRIL; NASDAQ: TRIN), the world’s leading source of intelligent information for businesses and professionals, today announced a plan to unify its dual listed company (DLC) structure. The Thomson Reuters Board of Directors has unanimously determined that unifying the company’s capital structure is in the best interests of all shareholders, as it will consolidate and improve the trading of the company’s shares and simplify its capital structure.  The Board recommends that all shareholders vote in favor of unification at shareholder meetings scheduled for August 7, 2009.

If unification is approved, Thomson Reuters will remain listed on the Toronto Stock Exchange and New York Stock Exchange and will no longer be listed on the London Stock Exchange and Nasdaq.

Following the proposed unification, Thomson Reuters PLC shareholders will have the same economic interest in Thomson Reuters as they do under the current DLC structure. Thomson Reuters PLC shareholders will receive one share in Thomson Reuters Corporation for every PLC share held. Holders of Thomson Reuters PLC American Depositary Shares (ADSs) will receive six Thomson Reuters Corporation common shares for each ADS held. Holders of Thomson Reuters Corporation common shares will continue to hold their existing shares. The proposed unification should not be a taxable transaction for shareholders based in Canada, the United Kingdom or the United States.

Thomson Reuters chief executive officer Thomas H. Glocer said, “The equity markets are increasingly global and electronic, and our investors deserve the very best capital structure we can provide. Our Board has determined that consolidating the trading of our shares into a single, global and deep pool of liquidity, listed on the Toronto and New York Stock Exchanges, is in the best interests of all shareholders.”

“When we formed Thomson Reuters, we believed a DLC structure was the best way for Reuters shareholders to stay invested in our shares and participate in our growth,” said Mr. Glocer.  “However, the shareholders of Thomson Reuters have changed considerably, and U.K. shareholders now only constitute 5% of the combined shareholder base.  Following the proposed unification, we hope that wherever possible shareholders currently holding London-traded PLC shares will stay invested in our company through our TSX and NYSE listed shares.”

 “Our commitment to customers, employees and other stakeholders in London, the United Kingdom and Europe is unchanged by where we list our shares.  London is a vital global capital for the markets that we serve, and home to more than 5,000 of our employees,” said Mr. Glocer.

The proposed unification will have no impact on Thomson Reuters global businesses, operations, strategy, financial position or employees.  Further, it will have no impact on dividend policy, credit ratings, the composition of the Board or the senior management team. The Reuters Trust Principles will continue to apply to all of Thomson Reuters. The company also reconfirmed its full-year guidance including revenue growth.

In connection with unification, Thomson Reuters may repurchase the equivalent of up to US$500 million of shares in one or more of its markets.

The proposed unification requires the approval of shareholders of both Thomson Reuters Corporation and Thomson Reuters PLC, voting separately, as well as U.K. court approval. Shareholder meetings will be held on August 7, 2009 in Toronto and London. The Woodbridge Company Limited, the controlling shareholder of Thomson Reuters, has committed to vote in favor of the proposed unification. If shareholders approve the proposed unification and the requisite court approval is obtained, it is expected that unification will occur by the end of the third quarter of 2009.  The City Code on Takeovers and Mergers (the “Takeover Code”) will not apply to the proposed unification and, following closing,  Thomson Reuters will no longer be subject to the Takeover Code.

Holders of Thomson Reuters Corporation common shares as of 5:00 p.m. (Eastern Daylight Time) on July 2, 2009 and holders of Thomson Reuters PLC ordinary shares as of 6:00 p.m. (British Summer Time) on August 5, 2009 will be entitled to vote at the meetings.

Additional information will be provided in the Thomson Reuters management information circular and notice of meeting, which will be available in the next few weeks.
