September 2019 NYSE: CCC Presentation

| 2 Forward - Looking Statements The accompanying materials contain certain forward - looking statements regarding Clarivate Analytics Plc (the “Company” or “ Clarivate ”), its financial condition and its results of operations, anticipated synergies and other future expectations . Forward - looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by which, if at all, such performance or results will be achieved . All of these statements are based on estimates and assumptions prepared by the Company’s management as of the date of this presentation that, although the Company believes to be reasonable as of such date, are inherently uncertain . These statements involve risks and uncertainties, including, but not limited to, statements regarding our intentions, beliefs or current expectations concerning, among other things, Clarivate’s results of operations, financial condition, liquidity, prospects, growth, strategies and the markets in which the Company operates . Forward - looking statements speak only as of the date the statements are made . The Company undertakes no obligation to update or revise any of the forward - looking statements contained herein, whether as a result of new information, future events or otherwise . If the Company does update one or more forward - looking statements, no inference should be drawn that the Company will make any additional updates with respect thereto or with respect to any other forward - looking statements . The consolidated financial information presented herein was based on certain assumptions and estimates, and may not necessarily reflect the results of operations that would have occurred if the Company had been a separate, standalone entity during the periods presented or the Company’s future results of operations . In addition, the estimated costs and anticipated cost savings presented herein, are based on management’s expectations, beliefs and projections, are subject to change and there can be no assurance that such expectations or projections will be achieved . Non - GAAP Financial Measures This presentation contains financial measures which have not been calculated in accordance with United States generally accepted accounting principles, consistently applied (“GAAP”), including Adjusted Revenues, Adjusted EBITDA and Adjusted EBITDA Margin, 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 are 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 . We urge you to review Clarivate’s financial statements contained in the Form F - 4 filed by Clarivate Analytics Plc with the Securities and Exchange Commission (“the SEC”) on April 25 , 2019 . At the end of 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 measure . 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, dated as of October 3 , 2016 , governing the Company’s term loan facility and revolving credit facility, as amended and/or supplemented from time to time (the “Credit Agreement”) and the indenture (the “Indenture”) governing the Company’s 7 . 875 % senior notes due 2024 (the “Notes”), 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 .

Presentation of certain non - GAAP financial measures | 27 Adjusted Revenue, Standalone Adjusted EBITDA, and Standalone Adjusted EBITDA Margin, as presented, are examples of supplement al non - GAAP measures of Clarivate’s performance. Adjusted Revenue normalizes for the impact of purchase accounting adjustments to deferred revenue and the impact o f divestments. Standalone Adjusted EBITDA is calculated using net income from continuing operations before provision for income taxes, depre cia tion and amortization and interest income and expense), adjusted to exclude acquisition or disposal - related transaction costs (such costs include net income from c ontinuing operations before provision for income taxes, depreciation and amortization and interest income and expense from the IPM product line which was divested in October 2018), losses on extinguishment of debt, stock - based compensation, unrealized foreign currency gains/(losses), Transition Services Agreement (“TS A”) costs, separation and integration costs, transformational and restructuring expenses, acquisition - related adjustments to deferred revenue, 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 Clarivate does not consider indicative of its ongoing operating performance, and certain unusual items impacting results in a particular period to more accurately reflect management’s view of the recurring profitability of the business, adjusted further to include the difference between annualized run - rate savi ngs and savings realized during that same fiscal year as well as the difference in Clarivate’s actual standalone costs incurred relative to the steady state standalone cost estimate that Clarivate expects to achieve after completion of the Transition and optimization of the standalone functions by 2021. Standalone Adjusted EBITDA Margin is de fined as Standalone Adjusted EBITDA divided by revenue before acquisition - related deferred revenue adjustments. In future periods, Clarivate 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 Clarivate considers them appropriate for supplemental analysis. These measures are not measurements of Clarivate’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 c ash 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 mea sur es of Clarivate’s liquidity. Reduction of ongoing standalone and transition services agreement costs have been, and are expected to continue to be, a comp one nt of Clarivate’s strategy as it finalizes its separation from Thomson Reuters Corporation. In this presentation, Clarivate sets forth its Standalone Adjusted EBITDA on a historical and projected basis. The adjustments reflected in Clarivate’s Standalone Adjusted EBITDA have not been prepared with a view towards complying with Article 11 of Regulation S - X. These standalone measures are intended to provide additional information on a more comparable basis than would be provided without suc h standalone adjustments. Certain of the adjustments included to arrive at Standalone Adjusted EBITDA are based on a historical and projected basis of exp ected costs related to Clarivate's transition to an independent company. In evaluating Standalone Adjusted EBITDA you should be aware that in the future Clarivate may incur expenses that are the same as or similar to some of the included adjustments. Our presentation of Standalone Adjusted EBITDA should not be construe d a s an inference that Clarivate's future results will be unaffected by any of the adjusted items, or that Clarivate's projections and estimates will be realized in their entirety or at all. Standalone Adjusted EBITDA is included in this presentation because Clarivate believes it is an important supplemental measure of Clarivate's operating performance and a basis upon which Clarivate's management assesses performance rather than cash flow measures. Our management also believes Standalone Adjusted EBITDA is useful to investors because they and similar measures are frequently used by securities analysts, investors, and other intere ste d parties to evaluate Clarivate's competitors and provide additional information regarding growth rates on a more comparable basis than would be provided witho ut such standalone adjustments. Adjusted revenue is included in this presentation because Clarivate believes it is an important supplemental measure of Clarivate’s operating performance and a basis upon which Clarivate’s management assesses performance. Our management believes Adjusted Revenue is useful to investors because it is frequently use d by securities analysts, investors, and other interested parties to evaluate performance and provide additional information regar din g growth rates on a more comparable basis than would be provided without such adjustments.

Presentation of certain non - GAAP financial measures ( cont’d) | 28 We also monitor Standalone Adjusted EBITDA because Clarivate’s credit agreement governing its credit facilities and its indenture governing its senior unsecured notes contain certain covenants (including debt incurrence and the making of restricted payments) based on a leverage ratio, whi ch uses Standalone Adjusted EBITDA. Standalone Adjusted EBITDA performance, along with the quantitative and qualitative information, may also be used by man agement and Clarivate’s Compensation Committee as an input for determining incentive payments to colleagues. The use of Standalone Adjusted EBITDA instead of U.S. GAAP measures has limitations as an analytical tool, and you should not co nsider Standalone Adjusted EBITDA in isolation or as a substitute for analysis of Clarivate’s results of operations and operating cash flows as reported under GAAP. For example, Standalone Adjusted EBITDA: • does not reflect Clarivate’s cash expenditures or future requirements for capital expenditures; • does not reflect changes in, or cash requirements for, Clarivate’s working capital needs; • does not reflect interest expense, or the cash requirements necessary to service interest or principal payments, on Clarivate’s debt; • does not reflect any cash income taxes or payments under the Tax Receivable Agreement that Clarivate may be required to pay; • does not reflect any cash requirements that may occur because assets are depreciated or amortized over estimated useful lives an d often have to be replaced in the future; and • does not reflect all non - cash income or expense items that are reflected in Clarivate’s statements of cash flows. Clarivate’s definition of and method of calculating Standalone Adjusted EBITDA may vary from the definitions and methods used by other co mp anies, which may limit their usefulness as comparative measures. Clarivate prepared the information included in this presentation based upon available information and assumptions and estimates that it b elieves are reasonable. Clarivate cannot assure you that its estimates and assumptions will prove to be accurate. Because Clarivate incurred transaction, transition, integration, transformation, restructuring, and transition services agreement costs in conn ec tion with its carve - out from Thomson Reuters, borrowed money in order to finance its operations, and used capital and intangible assets in its busine ss, and because the payment of income taxes is necessary if Clarivate generates taxable income after the utilization of its net operating loss carryforwards, any measure that excludes these items has material limitations.
