Release of Thomson Reuters Second-Quarter 2008 Report

NEW YORK, NY - August 13, 2008 - Thomson Reuters (NYSE: TRI; TSX: TRI; LSE: TRIL; NASDAQ: TRIN) today announced that it has filed a quarterly report for the period ended June 30, 2008 containing management's discussion and analysis and related financial statements. Thomson Reuters previously announced its second-quarter earnings through a news release on August 12, 2008. Please click on the link below for a PDF copy of the second-quarter report.

http://www.rns-pdf.londonstockexchange.com/rns/2648B_-2008-8-13.pdf</fip P> On April 17, 2008, The Thomson Corporation acquired Reuters Group PLC (Reuters) and Thomson Reuters was formed. Canadian GAAP results in the second-quarter report only reflect results of Reuters from the closing date of the acquisition. For informational purposes, the management's discussion and analysis included in the second-quarter report contains pro forma results which estimate the performance of the Thomson Reuters business as if Thomson acquired Reuters on January 1, 2007. Thomson Reuters believes that pro forma financial information provides more meaningful period-to-period comparisons of its performance because Reuters results prior to the April 17, 2008 closing date are not included in Canadian GAAP results.

The second-quarter report is available at www.thomsonreuters.com within the 'Investor Relations' section of the website. The report has also been filed with the Canadian securities regulatory authorities and is available on the SEDAR website at www.sedar.com, and it has also been furnished to the U.S. Securities and Exchange Commission through EDGAR on Form 6-K and is available at www.sec.gov. A copy of the report will be available shortly at the UKLA Document Viewing Facility of the Financial Services Authority at 25 The North Colonnade, London E14 5HS, United Kingdom.

Thomson Reuters operates under a dual listed company structure (DLC) and has two parent companies - Thomson Reuters Corporation and Thomson Reuters PLC. Thomson Reuters primary financial statements are the consolidated financial statements of Thomson Reuters Corporation contained in the second-quarter report. Those statements account for Thomson Reuters PLC as a subsidiary and have been prepared in accordance with Canadian GAAP. Unaudited interim financial information for Thomson Reuters PLC on a standalone basis as of and for the six months ended June 30, 2008 will be announced separately later this month. Thomson Reuters PLC standalone financial information will exclude the results of Thomson Reuters Corporation and will be prepared under International Financial Reporting Standards as adopted in the European Union (IFRS). This information, together with the second-quarter report announced today, will comprise the Thomson Reuters PLC half-yearly 2008 financial report in accordance with the requirements of the UK Disclosure and Transparency Rules. Thomson Reuters considers the second-quarter report announced today to be the most appropriate presentation of its results given the report includes those of both Thomson Reuters Corporation and Thomson Reuters PLC.
