Acceptance of this presentation further constitutes your acknowledgment and agreement that none of Cushman & Wakefield plc or any of its affiliates (i) makes any express or implied representation or warranty as to the accuracy or completeness of the information contained in this presentation or (ii) shall have any liability to the recipient or its representatives relating to or arising from the information contained in this presentation or any omissions from such information. This presentation speaks only as to the date hereof and the Company assumes no duty to update or revise the information contained in this presentation. Figures in tables and charts in this presentation may not foot due to rounding. All statements in this presentation other than historical facts are forward-looking statements, which rely on a number of estimates, projections and assumptions concerning future events. Such statements are also subject to a number of uncertainties and factors outside Cushman & Wakefield’s control. Such factors include, but are not limited to, disruptions in general macroeconomic conditions and global and regional demand for commercial real estate; our ability to attract and retain members of our senior management and qualified revenue producing employees; disruptions to our business and to our clients’ businesses caused by COVID-19; the inability of our acquisitions and joint ventures to perform as expected and the unavailability of similar future opportunities; our ability to preserve, grow and leverage the value of our brand; the concentration of business with corporate clients; our ability to appropriately address actual or perceived conflicts of interest; our ability to maintain and execute information technology strategies, maintain the security of our information and adapt to changes in technology; interruption or failure of our information technology, communications systems or data services; our vulnerability to material breaches related to our information technology; our ability to comply with current and future data privacy regulations and other confidentiality obligations; the extent to which natural disasters, global health crises, building defects, terrorist attacks and mass shootings may disrupt our ability to manage client properties; the potential impairment of our goodwill and other intangible assets; our ability to comply with new laws or regulations or changes in existing laws or regulations and to make correct determinations in complex tax regimes; our ability to execute on our strategy for operational efficiency; the seasonality of significant portions of our revenue and cash flow; the failure of third parties to comply with contract, regulatory or legal requirements; risks associated with the effects of climate change and ability to achieve our sustainability goals; the possibility that we may be subject to environmental liability as a result of our role as a real estate services provider; our ability to compete globally, regionally and locally; social, political and economic risks in different countries as well as foreign currency volatility; the ability of our principal shareholders to exert significant influence over us; the effects from either us or our existing shareholders selling a large number of ordinary shares in the market; our intention or ability to pay cash dividends on our ordinary shares; uncertainties related to the timing and amount of any potential share repurchases; the operating and financial restrictions that our 2018 Credit Agreement and the indenture governing the 2020 Notes impose on us and the possibility that in an event of default all of our borrowings may become immediately payable; our substantial indebtedness; the potential that we may incur more debt; our ability to generate sufficient cash flow from operations to satisfy our debt service obligations; risks related to litigation; the fact that the rights of our shareholders differ in certain respects from the rights typically offered to shareholders of a Delaware corporation; the fact that U.S. investors may have difficulty enforcing liabilities against us or be limited in their ability to bring a claim in a judicial forum they find favorable in the event of a dispute; and the possibility that English law and provisions in our articles of association may have anti-takeover effects that could discourage an acquisition of us by others or require shareholder approval for certain capital structure decisions. Should any Cushman & Wakefield estimates, projections and assumptions or these other uncertainties and factors materialize in ways that Cushman & Wakefield did not expect, there is no guarantee of future performance and the actual results could differ materially from the forward-looking statements in this presentation, including the possibility that recipients may lose a material portion of the amounts invested. While Cushman & Wakefield believes the assumptions underlying these forward-looking statements are reasonable under current circumstances, recipients should bear in mind that such assumptions are inherently uncertain and subjective and that past or projected performance is not necessarily indicative of future results.

You are cautioned not to place undue reliance on such forward-looking statements or other information in this presentation and should rely on your own assessment of an investment or a transaction. Any estimates or projections as to events that may occur in the future are based upon the best and current judgment of Cushman & Wakefield as actual results may vary from the projections and such variations may be material. Any forward-looking statements speak only as of the date of this presentation and, except to the extent required by applicable securities laws, Cushman & Wakefield expressly disclaims any obligation to update or revise any of them, whether as a result of new information, future events or otherwise. Additional information concerning factors that may influence the Company’s results is discussed under “Risk Factors” in Part I, Item 1A of its Annual Report on Form 10-K for the year ended December 31, 2022 and in its other periodic reports filed with the Securities and Exchange Commission (the “SEC”).

NON-GAAP FINANCIAL MEASURES AND OTHER FINANCIAL INFORMATION This presentation uses the following financial measures, which are considered non-GAAP financial measures under SEC guidelines: i. Free cash flow; ii.Adjusted earnings before interest, taxes, depreciation and amortization ( Adjusted EBITDA ) and Adjusted EBITDA margin; iii.Local currency; and iv.Net Debt Our management principally uses these non-GAAP financial measures to evaluate operating performance, develop budgets and forecasts, improve comparability of results and assist our investors in analyzing the underlying performance of our business. These measures are not recognized measurements under GAAP. When analyzing our operating results, investors should use them in addition to, but not as an alternative for, the most directly comparable financial results calculated and presented in accordance with GAAP. Because the Company’s calculation of these non-GAAP financial measures may differ from other companies, our presentation of these measures may not be comparable to similarly titled measures of other companies. The Company believes that these measures provide a more complete understanding of ongoing operations, enhance comparability of current results to prior periods and may be useful for investors to analyze our financial performance. The measures eliminate the impact of certain items that may obscure trends in the underlying performance of our business. The Company believes that they are useful to investors for the additional purposes described below. Free cash flow: Free cash flow is a financial performance metric which consists of net cash provided by (used in) operating activities and payment for property and equipment. Adjusted EBITDA and Adjusted EBITDA margin: We have determined Adjusted EBITDA to be our primary measure of segment profitability. We believe that investors find this measure useful in comparing our operating performance to that of other companies in our industry because these calculations generally eliminate integration and other costs related to merger, pre-IPO stock-based compensation, unrealized (gains) / losses on investments, acquisition related costs and efficiency initiatives, cost savings initiatives, CEO transition costs and other non-recurring items. Adjusted EBITDA also excludes the effects of financings, income tax and the non-cash accounting effects of depreciation and intangible asset amortization. Adjusted EBITDA margin, a non-GAAP measure of profitability as a percent of revenue, is measured against service line fee revenue. Service line fee revenue represents revenue for fees generated from each of our service lines. EBITDA as defined in the Issuer’s Senior Secured Credit Facilities and as defined in the indenture governing the Notes will allow for certain addbacks and adjustments that are not included in the Company's Adjusted EBITDA as presented in this presentation. Local currency: In discussing our results, we refer to percentage changes in local currency. These metrics are calculated by holding foreign currency exchange rates constant in year-over-year comparisons. Management believes that this methodology provides investors with greater visibility into the performance of our business excluding the effect of foreign currency rate fluctuations. Net Debt: Net debt is used as a measure of our liquidity and is calculated as total debt minus cash and cash equivalents. With respect to the Company’s guidance language, the Company is not able to provide a reconciliation of these non-GAAP financial measures to GAAP because it cannot provide specific guidance for the various extraordinary, nonrecurring or unusual charges and other certain items. These items have not yet occurred and/or cannot be reasonably predicted. As a result, reconciliation of the non-GAAP guidance measures to GAAP is not available without unreasonable effort and the Company is unable to address the probable significance of the unavailable information. The interim financial information for the three months ended June 30, 2023 and 2022 is unaudited. All adjustments, consisting of normal recurring adjustments, except as otherwise noted, considered necessary for a fair presentation of the unaudited interim condensed consolidated financial information for these periods have been included. Users of all of the aforementioned unaudited interim financial information should refer to the audited Consolidated Financial Statements of the Company and notes thereto for the year ended December 31, 2022 in the Company's 2022 Annual Report on Form 10-K.
