willistowerswatson.com Willis Towers Watson Non - GAAP Measures © 2021 Willis Towers Watson. All rights reserved. In order to assist readers of our consolidated financial statements in understanding the core operating results that Willis T owe rs Watson’s management 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 O perating 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 Ra te and (9) Free Cash Flow. The Company believes that these measures are relevant and provide useful information widely used by analysts, investors and o the r 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 fo reign currency impacts necessary for a quantitative reconciliation of these forward - looking non - GAAP financial measures to the most directly comparable U.S. GAAP financial measure, is available to t he Company without unreasonable efforts. For the same reasons, the Company is unable to address the probable significance of the unavailable information. The Company provides non - GAA P financial measures that it believes will be achieved, however it cannot accurately predict all of the components of the adjusted calculations and the U.S. GAAP measures may be mat eri ally different than the non - GAAP measures. 2
