Q4 and Full Year 2020 Earnings Supplemental Materials February 25, 2021

2 Forward-Looking Statements These materials contain “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. 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, outlook, anticipated cost savings, 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 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 2019 annual report on Form 10-K, our current report on Form 8-K filed on June 19, 2020, and our quarterly report on Form 10-Q for the quarters ended March 31, June 30 and September 30, 2020, 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. Forward-looking statements are based only on information currently available to our management and speak only as of the date of this press release. 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 Revenues, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Diluted EPS, Free Cash Flow, Adjusted Free Cash Flow, Standalone Adjusted EBITDA, and net debt 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 and performance or 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. Results excluding divestitures in this presentation exclude the previously announced November 6, 2020 divestiture of Techstreet and the January 1, 2020 divestiture of the MarkMonitor brand protection, antipiracy and antifraud product. Clarivate retained the MarkMonitor Domain Management business. Required Reported Data We are required to report Standalone Adjusted EBITDA, which is identical to Consolidated EBITDA and EBITDA as such terms are defined under our credit agreement, and the indenture governing our senior secured notes due 2026, respectively, pursuant to the reporting covenants contained in such agreements. In addition, management of the Company uses Standalone Adjusted EBITDA to assess compliance with various incurrence-based covenants in these agreements.

APPENDIX

16 Presentation of Certain Non-GAAP Financial Measures This presentation contains financial measures which have not been calculated in accordance with GAAP, including Adjusted Revenues and Adjusted EBITDA, 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. Adjusted Revenues Adjusted Revenues excludes the impact of the deferred revenues purchase accounting adjustment (primarily recorded in connection with recent acquisitions). Our presentation of Adjusted Revenues is presented for informational purposes only and is not necessarily indicative of our future results. You should compensate for these limitations by relying primarily on our GAAP results and only using Adjusted Revenues for supplementary analysis. Adjusted EBITDA Adjusted EBITDA is calculated using net (loss) income before provision for income taxes, depreciation and amortization and interest income and expense adjusted to exclude 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), stock-based compensation, unrealized foreign currency gains/(losses), transition services agreement costs entered into with Thomson Reuters in 2016 ("Transition Services Agreement"), separation and integration costs, transformational and restructuring expenses, acquisition-related adjustments to deferred revenues, non-cash income/(loss) on equity and cost method investments, non-operating income or expense, the impact of certain non-cash 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 future periods, the Company will need to make additional capital expenditures in order to replicate capital expenditures associated with previously shared services on a stand-alone basis. You are encouraged to evaluate these adjustments and the reasons the Company considers them appropriate for supplemental analysis. These measures are not measurements of the Company’s financial performance under GAAP and should not be considered in isolation or as alternatives to net income, net cash flows provided by operating activities, total net cash flows or any other performance measures derived in accordance with GAAP or as alternatives to net cash flows from operating activities or total net cash flows as measures of the Company’s liquidity. Reduction of ongoing standalone and Transition Services Agreement costs have been, and are expected to continue to be, a component of the Company’s strategy as it finalizes its transition to a standalone company following the 2016 Transaction. Certain of the adjustments included to arrive at Adjusted EBITDA are related to the Company’s transition to an independent company. 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.

17 Presentation of Certain Non-GAAP Financial Measures The use of Adjusted EBITDA instead of GAAP measures 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 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. Because the Company incurred transaction, transition, integration, transformation, restructuring, and Transition Services Agreement costs in connection with the 2016 Transaction and the transition, borrowed money in order to finance its operations, and used capital and intangible assets in its business, and because the payment of income taxes is necessary if the Company generates taxable income after the utilization of its net operating loss carryforwards, any measure that excludes these items has material limitations. As a result of these limitations, these measures should not be considered as a measure of discretionary cash available to the Company to invest in the growth of its business or as a measure of its liquidity. Adjusted EBITDA Margin Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by Adjusted Revenues.

18 Presentation of Certain Non-GAAP Financial Measures Adjusted Net Income and Adjusted Diluted EPS We have begun to 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 provision for income taxes, depreciation and amortization and interest income and expense from the divested business), amortization related to acquired intangible assets, stock-based compensation, unrealized foreign currency gains/(losses), Transition Services Agreement costs, separation and integration costs, transformational and restructuring expenses, acquisition-related adjustments to deferred revenues, non-cash income (loss) on equity and cost method investments, non- operating income or expense, the impact of certain non-cash and other items that are included in net income for the period that the Company does not consider indicative of its ongoing operating performance, 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 pursuant to the reporting covenants contained in the Credit Agreement and the Indenture. Standalone Adjusted EBITDA is identical to Consolidated EBITDA and EBITDA as such terms are defined under the Credit Agreement and the Indenture, respectively. In addition, the Credit Agreement and the Indenture 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 and excess standalone costs. Because Standalone Adjusted EBITDA is required pursuant to the terms of the reporting covenants under the Credit Agreement and the Indenture 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 as an input for determining incentive payments to employees. Excess standalone costs are the difference between our actual standalone company infrastructure costs, and our estimated steady state standalone infrastructure costs. We make an adjustment for the difference because we have had to incur costs under the Transition Services Agreement after we had implemented the infrastructure to replace the services provided pursuant to the Transition Services Agreement, after we had implemented the infrastructure to replace the services provided pursuant to the Transition Services Agreement, thereby incurring dual running costs. Furthermore, there has been a ramp up period for establishing and optimizing the necessary standalone infrastructure. Since our separation from Thomson Reuters, we have had to transition quickly to replace services provided under the Transition Services Agreement, with optimization of the relevant standalone functions typically following thereafter. Cost savings reflect the annualized “run rate” expected cost savings, net of actual cost savings realized, related to restructuring and other cost savings initiatives undertaken during the relevant period. Standalone Adjusted EBITDA is calculated under the Credit Agreement and the Indenture by using our Net Income for the trailing twelve month period (defined in the Credit Agreement and the Indenture as our GAAP net income adjusted for certain items specified in the Credit Agreement and the Indenture) adjusted for items including: taxes, interest expense, depreciation and amortization, non-cash charges, 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 following the separation of the Company’s business from Thomson Reuters (the “2016 Transaction”) 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 Notes 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 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 transition services agreement, transition, transformation and integration expenses, transaction related costs and debt issuance costs offset by cash received for hedge accounting transactions.

20 Diluted Share Count 1 2 3 3 4 5 6 7 Note: the analysis is not intended to replace the Treasury Stock Method as required under ASC 260, Earnings per Share 1. Inconsistent with the requirements of ASC 260, but for illustrative purposes, this analysis uses hypothetical shares prices and not the actual average share price for the period as required under US GAAP. 2. Debt and cash amounts reflect 12/31/20 balances. 3. Per the requirements of the Treasury Stock Method this excludes all management options that are antidilutive at the assumed share prices in this analysis and includes consideration of unrecognized compensation costs. 4. Consists of actual 2019 and 2020, as well as forecasted 2021 RSUs and their related activity. This includes forecasted issuances of 1.8M RSUs in 2021. 5. Consistent with the requirements of ASC 260, performance conditions for 0.6M of the PSUs granted in 2020 are not likely to be achieved as of this time, and therefore are excluded from this dilution analysis. Market conditions for 0.3M of the PSUS granted in 2020 are likely to be achieve based on the stock price's performance in the past year, and therefore are included in this dilution analysis. This figure does not include forecasted PSU grants for 2021 since the probability of achieving related performance obligations is unable to be measured at this time. 6. Consistent with the requirement of ASC 260, the impact of 2.9M estimated shares to be issued on the one year anniversary of acquisition of DRG (February 28, 2021) is included within this dilution analysis. 7.
