Q3 2022 Earnings Call November 8, 2022

Forward-Looking Statements This communication contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. These statements, which express management’s current views concerning future business, events, trends, contingencies, financial performance, or financial condition, appear at various places in this communication and may use words like “aim,” “anticipate,” “assume,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “future,” “goal,” “intend,” “likely,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “see,” “seek,” “should,” “strategy,” “strive,” “target,” “will,” and “would” and similar expressions, and variations or negatives of these words. Examples of forward- looking statements include, among others, statements we make regarding: guidance outlook and predictions relating to expected operating results, such as revenue growth and earnings; strategic actions such as acquisitions, joint ventures, and dispositions, including the anticipated benefits therefrom, and our success in integrating acquired businesses; anticipated levels of capital expenditures in future periods; our ability to successfully realize cost savings initiatives and transition services expenses; our belief that we have sufficient liquidity to fund our ongoing business operations; expectations of the effect on our financial condition of claims, litigation, environmental costs, the impact of inflation, the impact of foreign currency fluctuations, the COVID-19 pandemic and governmental responses thereto, contingent liabilities, and governmental and regulatory investigations and proceedings; and our strategy for customer retention, growth, product development, market position, financial results, and reserves. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on management’s current beliefs, expectations, and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy, and other future conditions. Because forward-looking statements relate to the future, they are difficult to predict and many of which are outside of our control. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include those factors discussed under the caption “Risk Factors” in our annual report on Form 10-K, along with our other filings with the U.S. Securities and Exchange Commission (“SEC”). However, those factors should not be considered to be a complete statement of all potential risks and uncertainties. Additional risks and uncertainties not known to us or that we currently deem immaterial may also impair our business operations. Forward-looking statements are based only on information currently available to our management and speak only as of the date of this communication. We do not assume any obligation to publicly provide revisions or updates to any forward-looking statements, whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws. Please consult our public filings with the SEC or on our website at www.clarivate.com. Non-GAAP Financial Measures This presentation contains financial measures which have not been calculated in accordance with United States generally accepted accounting principles (“GAAP”), including Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow, Adjusted Free Cash Flow, Standalone Adjusted EBITDA, and Organic/Inorganic Revenues because they are a basis upon which our management assesses our performance, and we believe they reflect the underlying trends and indicators of our business. Although we believe these measures may be useful for investors for the same reasons, these financial measures should not be considered as an alternative to GAAP financial measures as a measure of the Company’s financial condition, profitability, performance and liquidity. In addition, these financial measures may not be comparable to similar measures used by other companies. At the Appendix to this presentation, we provide further descriptions of these non-GAAP measures and reconciliations of these non-GAAP measures to the corresponding most closely related GAAP measures.

This presentation contains financial measures which have not been calculated in accordance with generally accepted accounting principles in the United States of America (“US GAAP“), including Organic/Inorganic Revenues, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow and Adjusted Free Cash Flow because they are a basis upon which our management assesses our performance, and we believe they reflect the underlining trends and indicators of our business. Organic/Inorganic Revenues Organic revenues illustrates growth in businesses owned by the Company as of January 1, 2021 at constant currency. Inorganic revenues illustrates via growth in the business via acquisitions. Adjusted EBITDA Adjusted EBITDA represents net loss before the provision for income taxes, depreciation and amortization, interest income and expense adjusted to exclude the acquisition or disposal-related transaction costs (such costs include net income from continuing operations before provision for income taxes, depreciation and amortization and interest income and expense from divestitures), share-based compensation, mandatory convertible preferred share dividend expense, unrealized foreign currency gains (losses), transformational and restructuring expenses, acquisition-related adjustments to deferred revenues, non-operating income or expense, the impact of certain non-cash, mark-to-market adjustments on financial instruments, legal settlements and other items that are included in net income for the period that the Company does not consider indicative of its ongoing operating performance and certain unusual items impacting results in a particular period. In evaluating Adjusted EBITDA, you should be aware that in the future the Company may incur expenses that are the same as or similar to some of the included adjustments. The Company’s presentation of Adjusted EBITDA should not be construed as an inference that the Company’s future results will be unaffected by any of the adjusted items, or that the Company’s projections and estimates will be realized in their entirety or at all. Presentation of Certain Non-GAAP Financial Measures © 2022 Clarivate Plc. All rights reserved.

Adjusted EBITDA The use of Adjusted EBITDA instead of US GAAP has limitations as an analytical tool, and you should not consider Adjusted EBITDA in isolation, or as a substitute for analysis of the Company’s results of operations and operating cash flows as reported under US GAAP. For example, Adjusted EBITDA does not reflect: – the Company’s cash expenditures or future requirements for capital expenditures – changes in, or cash requirements for, the Company’s working capital needs – interest expense, or the cash requirements necessary to service interest or principal payments, on the Company’s debt – any cash income taxes that the Company may be required to pay – any cash requirements for replacements of assets that are depreciated or amortized over their estimated useful lives and may have to be replaced in the future – all non-cash income or expense items that are reflected in the Company’s statements of cash flows The Company’s definition of and method of calculating Adjusted EBITDA may vary from the definitions and methods used by other companies when calculating adjusted EBITDA, which may limit their usefulness as comparative measures. The Company prepared the information included in this presentation based upon available information and assumptions and estimates that it believes are reasonable. The Company cannot assure you that its estimates and assumptions will prove to be accurate. Adjusted EBITDA Margin Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by Revenues, net plus the impact of the deferred revenue purchase accounting adjustments relating to acquisitions prior to 2021.

Adjusted Net Income and Adjusted Diluted EPS We use Adjusted Net Income and Adjusted Diluted Earnings Per Share ("Adjusted Diluted EPS") in our analysis of the financial performance of the Company. We believe Adjusted Net Income and Adjusted Diluted EPS are meaningful measures of the performance of the Company because they adjust for items that do not directly affect our ongoing operating performance in the period. Adjusted Net Income is calculated using net income (loss), adjusted to exclude acquisition or disposal-related transaction costs (such costs include net income from continuing operations before the provision for income taxes, depreciation and amortization and interest income and expense from the divested business), amortization related to acquired intangible assets, share-based compensation, mandatory convertible preferred share dividend expense, unrealized foreign currency gains/(losses), transformational and restructuring expenses, acquisition-related adjustments to deferred revenues, the impact of certain non-cash mark-to-market adjustments on financial instruments, interest on debt held in escrow, and other items that are included in net income for the period that the Company does not consider indicative of its ongoing operating performance and certain unusual items impacting results in a particular period, and the income tax impact of any adjustments. We calculate Adjusted Diluted EPS by using Adjusted Net Income divided by diluted weighted average shares for the period. Standalone Adjusted EBITDA We are required to report Standalone Adjusted EBITDA, which is identical to Consolidated EBITDA and EBITDA as such terms are defined under our credit facilities, dated as of October 31, 2019, and the indentures governing our secured notes due 2026 issued by Camelot Finance S.A. and guaranteed by certain of our subsidiaries, and the indentures governing the secured and unsecured notes issued by Clarivate Science Holdings Corporation in August 2021, respectively. In addition, the credit facilities and the indentures contain certain restrictive covenants that govern debt incurrence and the making of restricted payments, among other matters. These restrictive covenants utilize Standalone Adjusted EBITDA as a primary component of the compliance metric governing our ability to undertake certain actions otherwise proscribed by such covenants. Standalone Adjusted EBITDA reflects further adjustments to Adjusted EBITDA for cost savings already implemented. Because Standalone Adjusted EBITDA is required pursuant to the terms of the reporting covenants under the credit facilities and the indentures and because this metric is relevant to lenders and noteholders, management considers Standalone Adjusted EBITDA to be relevant to the operation of its business. It is also utilized by Management and the Compensation Committee of the Board of Directors as an input for determining incentive payments to employees. Standalone Adjusted EBITDA is calculated under the credit facilities and the indentures by using our Consolidated Net Loss for the trailing 12-month period (defined in the credit facilities and the indentures as our U.S. GAAP net income adjusted for certain items specified in the credit facilities and the indentures) adjusted for items including: taxes, interest expense, depreciation and amortization, non-cash charges, including goodwill impairment, expenses related to capital markets transactions, acquisitions and dispositions, restructuring and business optimization charges and expenses, consulting and advisory fees, run- rate cost savings to be realized as a result of actions taken or to be taken in connection with an acquisition, disposition, restructuring or cost savings or similar initiatives, “run rate” expected cost savings, operating expense reductions, restructuring charges and expenses and synergies related to the transition projected by us, costs related to any management or equity stock plan, other adjustments that were presented in the offering memorandum used in connection with the issuance of the secured notes due in 2026 and earnout obligations incurred in connection with an acquisition or investment.

Free Cash Flow and Adjusted Free Cash Flow We use free cash flow and adjusted free cash flow in our operational and financial decision-making and believe free cash flow and adjusted free cash flow is useful to investors because similar measures are frequently used by securities analysts, investors, ratings agencies and other interested parties to evaluate our competitors and to measure the ability of companies to service their debt. Free cash flow is calculated using net cash provided by operating activities, less capital expenditures. Adjusted free cash flow is calculated as free cash flow, less cash paid for restructuring and lease-exit activities, payments related to the CPA Global equity plan, transaction related costs, interest on debt held in escrow, debt issuance costs, and other one-time payments that the Company does not consider indicative of its ongoing operating performance.

Reconciliation of Non-GAAP Financial Measures (QTD) 1 Reflects the deferred revenues adjustment made as a result of purchase accounting prior to the adoption of ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.
