Although we believe that the assumptions underlying our forward - looking statements are reasonable, any of these assumptions, and therefore also the forward - looking statements based on these assumptions, could themselves prove to be inaccurate. Given the si gnificant uncertainties inherent in the forward - looking statements included in this document, our inclusion of this information is not a representation or guarantee by us that our objectives and plans will be achieved. Our forward - looking statements speak only as of the date made and we will not update these forward - looking statements unless the securities laws require us to do so. With regard to these risks, uncertainties and assumptions, the forward - looking events disc ussed in this document may not occur, and we caution you against unduly relying on these forward - looking statements. © 2025 WTW.

See “WTW Forward - Looking Statements“ above for information about forward - looking statements and cautionary language, including how actual results may differ materially from those in the slide presentation. WTW Non - GAAP Measures In order to assist readers of our consolidated financial statements in understanding the core operating results that WTW’s ma nag ement uses to evaluate the business and for financial planning, we present the following non - GAAP measures: (1) Constant Currency Change, (2) Organic Change, (3) Adjusted Operating Income/Margin, (4) Adjusted EBITDA/Margin, (5) Adjusted Net Income, (6) Adjusted Diluted Earnings Per Share, (7) Adjusted Income Before Taxes, (8) Adjusted Income Taxes/Tax Rate, (9) Free Cash Flow and (10) Free Cash Flow Margin. The Company believes that those measures are relevant and provide pertinent information widely used by analysts, investors an d o ther interested parties in our industry to provide a baseline for evaluating and comparing our operating performance, and in the case of free cash flow, our liquidity results. Reconciliations of these measures are included in the accompanying appendix of these earning release supplemental materials. The Company does not reconcile its forward - looking non - GAAP financial measures to the corresponding U.S. GAAP measures, due to v ariability and difficulty in making accurate forecasts and projections and/or certain information not being ascertainable or accessible; and because not all of the information, such as foreign currency impacts necessary for a quantit ati ve reconciliation of these forward - looking non - GAAP financial measures to the most directly comparable U.S. GAAP financial measure, is available to the Company without unreasonable efforts. For the same reasons, the Company is unable to a ddr ess the probable significance of the unavailable information. The Company provides non - GAAP financial measures that it believes will be achieved, however it cannot accurately predict all of the components of the adjusted calcul ati ons and the U.S. GAAP measures may be materially different than the non - GAAP measures. 3
