Thomson Reuters Provides Supplemental Financial Information Following Close of Global Print Transaction

TORONTO, October 19, 2026 -- As previously announced on October 1, 2026, Thomson Reuters (TSX/Nasdaq: TRI) (“the company”) sold a 51% stake in its Global Print business to capital accounts advised by KKR, with the two parties forming a joint venture to operate the Global Print business, now operating as Westbridge Print.

As a result of this transaction, Thomson Reuters will report Global Print as discontinued operations beginning in the third-quarter of 2026. Prior periods presented will be restated to reflect this change. A supplemental schedule has been posted to the “Investor Relations” section of thomsonreuters.com with revised 2025 and 2026 results that exclude the Global Print business.

On August 5, 2026, the company provided a third-quarter 2026 outlook for organic revenue growth of approximately 8% and adjusted EBITDA margin of approximately 36%, which included the results of the Global Print business. Calculated on the basis the company will use to report its third-quarter results, the previously provided outlook would have been approximately 9% organic revenue growth and approximately 35% adjusted EBITDA margin.

The revised historical information and the third-quarter 2026 outlook do not reflect certain arrangements that began on October 1, 2026, namely:

• Westbridge Print will pay a royalty to Thomson Reuters equal to 20% of its Professional revenue (approximately 85% – 90% of total Westbridge Print revenue) for the exclusive license to distribute the company’s intellectual property in print and on ProView, its eBook platform.

• Westbridge Print has entered into a multi-year agreement with Thomson Reuters where it will reimburse the company for certain transition services as the joint venture migrates to a standalone entity.

Beginning with fourth-quarter results, the impact of the royalty and transitional services arrangements are expected to largely offset stranded costs from the separation. As a result, the company continues to expect the impact from the Global Print transaction to be approximately neutral to adjusted EBITDA margin following the transaction close, as well as 60 – 70 basis points accretive to annual organic revenue growth.

The company will issue a revised full-year 2026 outlook when it reports its third-quarter earnings on November 3, 2026.

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 and accompanying web site post include certain non-IFRS financial measures, which include ratios that incorporate one or more non-IFRS financial measures, such as adjusted EBITDA (other than at the customer segment level) and the related margin, adjusted earnings and adjusted EPS, as well as financial measures for the “Big 3” segments. Non-IFRS financial measures are defined and reconciled to the most directly comparable IFRS measures in the supplemental schedules provided herein and on the website. Changes in revenues computed on an organic basis represent changes in revenues of the company’s existing businesses at constant currency. The metric excludes the distortive impacts of acquisitions and dispositions from not owning the business in both comparable periods.

Thomson Reuters uses these non-IFRS financial measures as supplemental indicators of its operating performance and financial position as well as for internal planning purposes and the company’s business outlook. Additionally, Thomson Reuters uses non-IFRS measures as the basis for management incentive programs. 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. The company’s 2026 outlook contains various non-IFRS financial measures. The company believes that providing reconciliations of forward-looking non-IFRS financial measures in its outlook would be potentially misleading and not practical due to the difficulty

Thomson Reuters Provides Supplemental Financial Information Following Close of Global Print Transaction of projecting items that are not reflective of ongoing operations in any future period. The magnitude of these items may be significant. Consequently, for purposes of its outlook only, the company is unable to reconcile these non-IFRS measures to the most directly comparable IFRS measures because it cannot predict, with reasonable certainty, the impacts of changes in foreign exchange rates which impact (i) the translation of its results reported at average foreign currency rates for the year, and (ii) other finance income or expense related to intercompany financing arrangements. Additionally, the company cannot reasonably predict the occurrence or amount of other operating gains and losses that generally arise from business transactions that the company does not currently anticipate.

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

Certain statements in this news release, including statements regarding the company’s expectations with respect to impacts from certain arrangements entered into with the Global Print joint venture are forward looking. The words “will”, “expect”, “believe”, “target”, “estimate”, “could”, “should”, “intend”, “predict”, “project” and similar expressions identify forward-looking statements. While the company believes that it has a reasonable basis for making forward-looking statements in this news release, they are not a guarantee of future performance or outcomes and there is no assurance that any of the other events described in any forward-looking statement will materialize. Forward-looking statements are subject to a number of risks, uncertainties and assumptions that could cause actual results or events to differ materially from current expectations. Many of these risks, uncertainties and assumptions are beyond the company’s control and the effects of them can be difficult to predict. 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, those discussed on pages 19-32 in the “Risk Factors” section of the company’s 2025 annual report. These and other risk 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 (SEC). Thomson Reuters’ annual and quarterly reports are also available in the “Investor Relations” section of thomsonreuters.com.

The company’s 2026 business outlook is based on information currently available to the company and is based on various external and internal assumptions made by the company in light of its experience and perception of historical trends, current conditions and expected future developments, as well as other factors that the company believes are appropriate under the circumstances. Material assumptions and material risks may cause actual performance to differ from the company’s expectations underlying its 2026 business outlook. In particular, the global economy has experienced substantial disruption due to concerns regarding economic effects associated with the macroeconomic backdrop and ongoing geopolitical risks. The company’s 2026 business outlook assumes that uncertain macroeconomic and geopolitical conditions will continue to disrupt the economy and cause periods of volatility, however, these conditions may last substantially longer than expected and any worsening of the global economic or business environment could impact the company’s ability to achieve its outlook and affect its results and other expectations. For a discussion of material assumptions and material risks related to the company’s 2026 outlook see pages 18-19 of the company’s second-quarter management’s discussion and analysis (MD&A) for the period ended June 30, 2026. The company’s quarterly MD&A was filed with, or furnished to, the Canadian securities regulatory authorities and the U.S. SEC and is also available in the “Investor Relations” section of thomsonreuters.com.

The company has provided an outlook for the purpose of presenting information about current expectations for the period presented. This information may not be appropriate for other 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.

(3) Reflects February 5, 2026 revisions between Legal Professionals, Corporates and Tax, Audit & Accounting Professionals to transfer certain customers reflecting how the segments are managed prospectively.

(1) The Company defines adjusted EBITDA as earnings or losses from continuing operations before tax expense or benefit, net interest expense, other finance costs or income, depreciation, amortization of software and other identifiable intangible assets, Thomson Reuters share of post-tax earnings or losses in equity method investments, other operating gains and losses, certain asset impairment charges, and fair value adjustments, including those related to acquired deferred revenue. The related margin is adjusted EBITDA expressed as a percentage of revenues. For purposes of this calculation, revenues are before fair value adjustments to acquired deferred revenue. See reconciliation of adjusted EBITDA margin included in this post. These measures provide a consistent basis to evaluate operating profitability and performance trends by excluding items that the Company does not consider to be controllable activities for this purpose.

(2) Fair value adjustments primarily represent gains or losses due to changes in foreign currency exchange rates on intercompany balances that arise in the ordinary course of business, which are a component of operating expenses, as well as adjustments related to acquired deferred revenue.

(1) The Company defines adjusted earnings as net earnings or loss including dividends declared on preference shares but excluding the post-tax impacts of fair value adjustments, including those related to acquired deferred revenue, amortization of acquired intangible assets (attributable to other identifiable intangible assets and acquired software), other operating gains and losses, certain asset impairment charges, other finance costs or income, our share of post-tax earnings or losses in equity method investments, discontinued operations and other items affecting comparability. Acquired intangible assets contribute to the generation of revenues from acquired companies, which are included in our computation of adjusted earnings. The post-tax amount of each item is excluded from adjusted earnings based on the specific tax rules and tax rates associated with the nature and jurisdiction of each item. Adjusted EPS is calculated from adjusted earnings using diluted weighted-average shares and does not represent actual earnings or loss per share attributable to shareholders. These measures provide a more comparable basis to analyze earnings and are commonly used by shareholders to measure performance.

(2) Fair value adjustments primarily represent gains or losses due to changes in foreign currency exchange rates on intercompany balances that arise in the ordinary course of business, which are a component of operating expenses, as well as adjustments related to acquired deferred revenue.

(3) In interim periods, the company makes an adjustment to reflect income taxes based on the estimated full-year effective tax rate. Earnings or losses for interim periods under IFRS reflect income taxes based on the estimated effective tax rates of each of the jurisdictions in which we operate. The non-IFRS adjustment reallocates estimated full-year income taxes between interim periods but has no effect on full-year income taxes.

(1) To compute segment and consolidated adjusted EBITDA margin, we exclude fair value adjustments related to acquired deferred revenue from our IFRS revenues. The chart above reconciles IFRS revenues to revenues used in the calculation of adjusted EBITDA margin, which excludes fair value adjustments related to acquired deferred revenue.

The Company reports its results in millions of U.S. dollars, but computes margins using whole-dollars to be more precise. As a result, adjusted EBITDA margins calculated from reported amounts may differ from those presented.
