  * First-quarter ongoing revenues up 1%, down 2% before currency

    revenues flat, down 4% before currency

NEW YORK, NY, May 4, 2010 - Thomson Reuters (TSX / NYSE: TRI), the world's
leading source of intelligent information for businesses and professionals,
today reported results for the first quarter ended March 31, 2010.  Despite the
flow-through effect of weak 2009 net sales, the company reported ongoing
revenues of $3.1 billion, underlying operating profit of $555 million,
underlying profit margin of 17.7% and underlying free cash flow of $107 million.

"The tentative recovery in our net sales that we began to see in the second half
of 2009 has firmed and accelerated in the first quarter of 2010.  We continue to
expect that we will see revenue growth return in the second half of this year,"
said Thomas H. Glocer, chief executive officer of Thomson Reuters.

"These improving market trends, coupled with our ongoing investment in new
products and scalable infrastructure, position us very well for revenue,
operating profit margin and cash flow growth in 2011 and beyond.  In particular,
the launch of WestlawNext in Legal in the first quarter, the launch of our
Elektron data distribution service in Enterprise in the second quarter, and the
scheduled launches in the second half of the year of our Eikon desktop in
Markets and our new ONESOURCE global tax workstation in Tax & Accounting, equip
our sales forces with new flagship offerings to sell into a rising economy."

release. Additional information is provided in the explanatory note at the end
of this news release.



  * Revenues from ongoing businesses were $3.1 billion, an increase of 1% after
    currency and a decrease of 2% before currency.  Good growth in Healthcare &
    Science, Tax & Accounting, Enterprise and Legal's subscription business was
    offset by expected softness in print and a decline in Sales & Trading and
    Investment & Advisory revenues due to flow-through from prior-year negative
    net sales.
  * Underlying operating profit declined 6%, attributable to flow-through from
    lower revenues, product mix and previously-announced investments.
  * Adjusted EPS was $0.36 compared to $0.40 in the prior-year period and
    included integration-related costs of $0.10 per share ($0.09 in the first
    quarter of 2009), which are included in adjusted earnings but excluded from
    underlying operating profit.
  * Underlying free cash flow was $107 million in what is traditionally the
    company's weakest quarter.
  * Integration and legacy savings programs continue to progress well, achieving
    run-rate savings of $1.2 billion.

Unless otherwise noted, all revenue growth comparisons in this news release are
before the impact of foreign currency as Thomson Reuters believes this provides
the best basis to measure the performance of its business. All revenue growth
and operating profit comparisons are based upon results from ongoing businesses
and exclude the results of disposals.

 Professional Division Total    22.3%    24.7%



  * First-quarter revenues rose 1%.  Healthcare & Science, Tax & Accounting and
    subscription Legal products combined for 5% growth, but were offset by
    declines in print and non-subscription products.
  * First-quarter operating profit declined 8%, as anticipated, primarily due to
    the impact of revenue flow-through in Legal, revenue mix and continued
    investment in the business.


Legal

  * First-quarter revenues declined 3%.  Subscription-based products grew 3%,
    led by 15% growth in FindLaw.  Non-subscription revenues declined 8% and
    print products declined 17% due to tightened customer budgets and timing
    benefits in the first half of 2009.
  * First-quarter operating profit declined 13% and the associated margin was
    25.5%.  Lower revenues, particularly from high-margin print and
    non-subscription products, more than offset efficiency savings.
  * WestlawNext launched on February 1, 2010 and has strengthened the company's
    competitive position with its clean, modern interface and powerful search
    functionality.  With approximately 2,300 WestlawNext customers to date, the
    product is well ahead of initial expectations and customer feedback has been
    extremely positive.


Tax & Accounting

  * First-quarter revenues grew 6%. Workflow & Software Solutions, which
    comprised two-thirds of the segment's revenues, grew 10%, led by income tax
    products and growth in the global tax businesses.  Business Compliance &
    Knowledge Solutions declined 3% as Checkpoint's growth of 6% was offset by a
    12% decline in print, which comprised 9% of the segment's revenues.
  * First-quarter operating profit declined 15% and the related margin fell to
    13.4%.  The anticipated declines were largely attributable to the dilutive
    impact of 2009 acquisitions.  Tax & Accounting is a seasonal business with
    nearly 50% of its operating profit traditionally generated in the fourth
    quarter.


Healthcare & Science

  * First-quarter revenues grew 9%.  Growth was driven by continued demand for
    healthcare spending analytics in Payer (up 10%), and outright sales and an
    acquisition in Scientific & Scholarly Research (up 13%).
  * First-quarter operating profit increased 42% versus 2009, and the
    corresponding margin was up almost 500 basis points to 21.2%.  These
    increases were attributable to flow-through from revenue growth, continued
    focus on expense management and one-time technology costs in the prior-year
    period.

 Operating Profit Margin %    17.5%    18.2%



  * First-quarter revenues declined 4%, attributable to flow-through from weak
    2009 net sales.
  * By geography, Asia was flat, while Europe, Middle East and Africa (EMEA) and
    the Americas declined 4% and 7%, respectively.
  * By market, growth in Commodities & Energy, Investment Banking and Enterprise
    was more than offset by declines in Fixed Income, Exchange Traded
    Instruments and Investment Management.
  * Sequential quarterly revenues from recurring subscriptions, transactions and
    recoveries were each up 2% in the first quarter of 2010 compared to the
    fourth quarter of 2009.
  * First-quarter operating profit declined 4% with the related margin
    declining, as expected, to 17.5%.  The margin decline was attributable to
    the impact of lower revenues.


Sales & Trading


  * First-quarter revenues decreased 7%. The decline was due to continued
    pressure on recoveries revenues and desktop reductions in the Exchange
    Traded Instruments and Fixed Income segments.
  * The Commodities & Energy sector benefitted from increased investment and a
    resilient market, growing 4% in the quarter.  Treasury was down 3% despite a
    4% increase in foreign exchange transaction revenues.


Investment & Advisory


  * First-quarter revenues declined 4%. The Investment Banking business grew 6%
    benefiting from improving market conditions and strong sales of
    ThomsonONE.com as well as certain timing effects.  Corporates grew 6%,
    driven primarily by recent acquisitions.
  * Investment Management revenues declined 9% in the first quarter as weak net
    sales in the first half of 2009 flowed through to reported results.
     Revenues were stable in the first quarter of 2010 versus the fourth quarter
    of 2009.
  * Wealth Management revenues declined as a result of the retirement of legacy
    desktop products (including ReutersPlus and ILX) as well as mergers among
    clients.


Enterprise


  * First-quarter revenues increased 3% against a difficult year-ago comparable
    period when revenues grew 11%.  Recurring revenues increased 5%, but overall
    growth was dampened by a decline in outright and transactions revenues.
  * Information Management Systems revenues (15% of total Enterprise revenues)
    increased 14%.  Enterprise Information revenues (60% of total Enterprise
    revenues) rose 4% driven by continued strong demand for pricing and related
    data.  Risk Management revenues were flat in the quarter.
  * Enterprise continues to benefit from the shift in demand from desktop to
    machine-based trading.


Media


  * First-quarter revenues declined 5% driven by weakness in the Agency business
    which continues to be impacted by tightened customer budgets.  The Consumer
    business transitioned to growth in the quarter.


Corporate & Other

First-quarter corporate costs were $163 million compared to $149 million in the
prior-year period.  The increase was primarily related to integration program
costs of $97 million, up $9 million, and fair-value currency-related adjustments
(non-cash) of $9 million, which were up $8 million. Core corporate costs were
$57 million, down $3 million.

Integration Programs

Thomson Reuters achieved combined run-rate savings of $1.2 billion at the end of
the first quarter of 2010 from the Reuters integration and legacy savings
programs.  An incremental $125 million increase in run-rate savings was
attributable to content consolidation and organizational realignment in the
Markets division and leveraging of the Thomson Reuters global footprint by the
Professional division.  Integration-related costs in the quarter totaled $97
million.

Recent Developments

In March 2010, Thomson Reuters issued $500 million principal amount of 5.85%
notes due 2040.  The company used the net proceeds from this offering (together
with available cash resources) to redeem all of its outstanding $700 million
principal amount of 6.20% notes due 2012.  As a result of these transactions,
the company extended the average maturity for its long-term debt to
approximately eight years.

Business Outlook (Before Currency)

Thomson Reuters today reaffirmed its business outlook for 2010 that was
previously communicated in February.

Based on the current environment in the markets that the company serves, Thomson
Reuters expects its revenues to be flat to slightly down in 2010 due to the
impact of negative net sales in 2009.  The company expects net sales to
strengthen throughout 2010.

The company expects its underlying operating profit margin to be comparable to
2009 before investments in the major new products and platforms launching this
year.  These investments are expected to have an impact of approximately 100
basis points.

The company's plan to continue its aggressive investment focus to drive growth
and capture efficiencies is likely to result in 2010 underlying free cash flow
being slightly down on the prior year.

The information in this section is forward-looking and should be read in
conjunction with the section below entitled "Special Note Regarding
Forward-Looking Statements, Material Assumptions and Material Risks."

Dividend

As previously announced, Thomson Reuters increased its 2010 dividend by $0.04
per share, resulting in a quarterly dividend of $0.29 per share and an
annualized dividend of $1.16 per share.  Thomson Reuters will pay a quarterly
dividend on June 15, 2010 to shareholders of record as of May 20, 2010.

Annual Renewal of Share Repurchase Facility

Thomson Reuters today announced that it has received approval from the Toronto
Stock Exchange (TSX) to renew its annual Normal Course Issuer Bid (NCIB) share
repurchase facility for an additional 12-month period.  Under the NCIB, up to
15 million common shares (representing less than 2% of the total outstanding
shares) may be repurchased in open market transactions on the TSX or the New
York Stock Exchange between May 13, 2010 and May 12, 2011.  On April 30, 2010,
there were 831,123,337 Thomson Reuters shares outstanding.  In accordance with
TSX rules, any daily repurchases would be limited to a maximum of 258,267
shares, which represents 25% of the average daily trading volume on the TSX for
the six months ended April 30, 2010.  Although Thomson Reuters has not
repurchased any shares since 2008, it may buy back shares (and subsequently
cancel them) from time to time as part of its capital management strategy.

NON-IFRS FINANCIAL MEASURES

Thomson Reuters prepares its financial statements in accordance with
International Financial Reporting Standards (IFRS), as issued by the
International Accounting Standards Board (IASB).

This news release includes certain non-IFRS financial measures. Thomson Reuters
uses these non-IFRS financial measures as supplemental indicators of its
operating performance and financial position. These measures do not have any
standardized meanings prescribed by IFRS and therefore are unlikely to be
comparable to the calculation of similar measures used by other companies, and
should not be viewed as alternatives to measures of financial performance
calculated in accordance with IFRS. Non-IFRS financial measures are defined and
reconciled to the most directly comparable IFRS measures in the appended tables.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS, MATERIAL ASSUMPTIONS AND
MATERIAL RISKS

Certain statements in this news release, including, but not limited to
statements in the "Integration Programs" and "Business Outlook (Before
Currency)" sections and Mr. Glocer's comments, are forward-looking. These
forward-looking statements are based on certain assumptions and reflect our
company's current expectations. As a result, forward-looking statements are
subject to a number of risks and uncertainties that could cause actual results
or events to differ materially from current expectations. There is no assurance
that the events described in any forward-looking statement will materialize. A
business outlook is provided for the purpose of presenting information about

purposes. You are cautioned not to place undue reliance on forward-looking
statements which reflect expectations only as of the date of this news release.
Except as may be required by applicable law, Thomson Reuters disclaims any
obligation to update or revise any forward-looking statements.

The material assumptions underlying the company's 2010 business outlook are
based on various external and internal assumptions. Economic and market
assumptions include, but are not limited to, positive global GDP growth led by
rapidly developing economies and a continued increase in the number of
professionals around the world and their demand for high quality information and
services. Internal financial and operational assumptions include, but are not
limited to, the successful execution of the company's new product release
programs, globalization strategy, other growth initiatives and efficiency
programs, including the integration program.

Some of the material risk factors that could cause actual results or events to
differ materially from those expressed in or implied by forward-looking
statements in this news release include, but are not limited to, changes in the
general economy; actions of competitors; increased accessibility to free or
relatively inexpensive information sources; failure to develop new products,
services, applications and functionalities to meet customers' needs, attract new
customers or expand into new geographic markets; failure to maintain a high
renewal rate for subscription-based services; failures or disruptions of network
systems or the Internet; detrimental reliance on third parties for information
and other services; changes to legislation and regulations; failure to meet the
challenges involved in operating globally; failure to protect the reputation of
Thomson Reuters; impairment of goodwill and identifiable intangible assets;
inadequate protection of intellectual property rights; threat of legal actions
and claims; downgrading of credit ratings and adverse conditions in the credit
markets; fluctuations in foreign currency exchange and interest rates; failure
to recruit and retain high quality management and key employees; the effect of
factors outside of the control of Thomson Reuters on funding obligations in
respect of pension and post-retirement benefit arrangements; actions or
potential actions that could be taken by the company's principal shareholder,
The Woodbridge Company Limited; failure to fully derive anticipated benefits
from future or existing acquisitions, joint ventures, investments or
dispositions; and failure to achieve benefits from integration programs to the
extent, or within the time period, currently expected. These and other factors
are discussed in materials that Thomson Reuters from time to time files with, or
furnishes to, the Canadian securities regulatory authorities and the U.S.
Securities and Exchange Commission. Thomson Reuters annual and quarterly reports

[1] Results for 2009 have been restated to reflect the 2010 presentation.
[2] Revenues and operating profit from ongoing businesses exclude the results of
disposals. Disposals include the results of businesses sold or held for sale
that do not qualify as discontinued operations.
[3]Underlying operating profit excludes amortization of other intangible assets,
impairment charges, fair value adjustments, integration program expenses, other
operating gains and losses and the results of disposals.  Underlying operating
profit margin is the underlying operating profit expressed as a percentage of
revenues from ongoing businesses.
[4] Adjusted earnings from continuing operations and adjusted earnings per share
from continuing operations include dividends declared on preference shares and
integration program expenses, but exclude the pre-tax impacts of amortization of
other intangible assets as well as the post-tax impacts of fair value
adjustments, other operating gains and losses, impairment charges, the results
of disposals (see note [2] above), other finance (income) costs, Thomson Reuters
share of post-tax earnings in equity method investees, discontinued operations
and other items affecting comparability.  Adjusted earnings per share from
continuing operations is calculated using diluted weighted average shares and
does not represent actual earnings per share attributable to shareholders.
[5]Adjustment to reflect income taxes based on estimated full-year effective tax
rate.  Reported earnings for interim periods reflect income taxes based on the
estimated effective tax rates of each of the jurisdictions in which Thomson
Reuters operates. The adjustment reallocates estimated full-year income taxes
between interim periods, but has no effect on full-year income taxes.

[1]  Free cash flow  is net cash  provided by operating  activities less capital
expenditures,  other investing activities,  investing activities of discontinued
operations  and dividends  paid on  our preference  shares. Thomson Reuters uses
free  cash flow as a performance measure because it represents cash available to
repay  debt,  pay  dividends  and  fund  share repurchases and new acquisitions.
[2]  Underlying free cash flow  is free cash flow  excluding one-time cash costs
associated with integration programs.
