Special Note Regarding Forward-Looking Statements, Material Risks and Material Assumptions

This presentation consists of these slides and the associated remarks and comments, which are related and intended to be presented and understood together.

Certain statements in this presentation and discussion are forward-looking, including, but not limited to, statements regarding the potential or expected impact of the COVID-19 pandemic on , its customers and the general economy, statements about the company’s third-quarter 2021 and full-year 2021-2023 outlook and other expectations regarding the future financial and operational performance of the company and its individual business segments, the company’s strategic priorities, initiatives and opportunities and the company’s expectations regarding its Change Program and share repurchases. While the company believes that it has a reasonable basis for making forward-looking statements in this presentation, they are not a guarantee of future performance or outcomes and there is no assurance that any of the events described in any forward-looking statement will materialize. Forward-looking statements, including those related to the COVID-19 pandemic, 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 our company’s control and the effects of them can be difficult to predict. In particular, the full extent of the impact of the COVID-19 pandemic on our business, operations and financial results will depend on numerous evolving factors that we may not be able to accurately predict. Some of the factors that could cause actual results to differ materially from current expectations are discussed in the “Risk Factors” section of our annual report and in other materials that we from time to time file with, or furnish to, the Canadian securities regulatory authorities and the U.S. Securities and Exchange Commission. Many of those risks are, and could be, exacerbated by the COVID-19 pandemic and any worsening of the global business and economic environment as a result.

Our company has provided a business outlook for the purpose of presenting information about current expectations for the third quarter of 2021 and full-year 2021-2023. 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 presentation. Except as may be required by applicable law, Thomson Reuters disclaims any obligation to update or revise any forward-looking statements.

The company’s 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. Please refer to our first quarter 2021 management’s discussion and analysis, which is available on www.tr.com, for a discussion of material assumptions and material risks related to our business outlook. Material assumptions and material risks related to our business outlook will also be reflected in our second-quarter 2021 management’s discussion and analysis for the period ended June 30, 2021, expected to be filed shortly.

Non-IFRS Financial Measures

This presentation contains disclosures of certain non-IFRS financial measures. These measures include adjusted EBITDA and the related margin, free cash flow, adjusted earnings, adjusted EPS and net debt to adjusted EBITDA leverage ratio, selected measures before the impact of currency and changes in revenues computed on an organic basis.

Please see our earnings release dated August 5, 2021, which is available on www.tr.com, for a reconciliation of each of Thomson Reuters’ measures to the most directly comparable IFRS financial measure. You can also find IFRS reconciliations in the “Investor Relations” section of our website.
