Willis Towers Watson Forward Looking Statements

This document contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. You can identify these statements and other forward-looking statements in this document by words such as "may", "will", "would", "expect", "anticipate", "believe", "estimate", "plan", "intend", "continue", or similar words, expressions or the negative of such terms or other

comparable terminology. These statements include, but are not limited to, such things as our outlook, the impact of the COVID-19 pandemic on our business, our pending business combination with Aon plc, future capital expenditures, ongoing working capital efforts, future share repurchases, growth in revenue, the impact of changes to tax laws on our financial results, existing and evolving business strategies and acquisitions and dispositions, demand for our services and competitive strengths, goals, the benefits of new initiatives, growth of our business and operations, our ability to successfully manage ongoing organizational and technology changes, including investments in improving systems and processes, and plans and references to future successes, including our future financial and operating results, plans, objectives, expectations and intentions and other statements that are not historical facts. Such statements are based upon the current beliefs and expectations of Willis Towers Watson's management and are subject to significant risks and uncertainties. Actual results may differ from those set forth in the forward-looking statements. All forward-looking disclosure is speculative by its nature.

There are important risks, uncertainties, events and factors that could cause our actual results or performance to differ materially from those in the forward-looking statements contained herein, including the following: the ability of the company to successfully establish, execute and achieve its global business strategy as it evolves; changes in demand for our services, including any decline in consulting services, defined benefit pension plans or the purchasing of insurance; changes in general economic, business and political conditions, including changes in the financial markets; the risk that the COVID- 19 pandemic substantially and negatively impacts the demand for our products and services and cash flows, and/or continues to materially impact our business operations, including increased demand on our information technology resources and systems and related risks of cybersecurity breaches or incidents; the risks relating to or arising from our pending business combination with Aon plc announced in March 2020, including, among others, our ability to consummate the transaction, including on the terms of the business combination agreement, on the anticipated timeline, and/or with the required regulatory approvals; significant competition that the company faces and the potential for loss of market share and/or profitability; the impact of seasonality and differences in timing of renewals; the failure to protect client data or breaches of information systems or insufficient safeguards against cybersecurity breaches or incidents; the risk of increased liability or new legal claims arising from our new and existing products and services, and expectations, intentions and outcomes relating to outstanding litigation; the risk the Stanford litigation settlement approval will be overturned on appeal, the risk that the Stanford bar order may be challenged in other jurisdictions, and the risk that the charge related to the Stanford settlement may not be deductible; the risk of substantial negative outcomes on existing litigation or investigation matters; changes in the regulatory environment in which the company operates, including, among other risks, the impact of pending competition law and regulatory investigations; various claims, government inquiries or investigations or the potential for regulatory action; the company's ability to make divestitures or acquisitions and its ability to integrate or manage such acquired businesses (including the recently-completed acquisition in Latin America); our ability to successfully hedge against fluctuations in foreign currency rates; our ability to integrate direct-to-consumer sales and marketing solutions with our existing offerings and solutions; the ability to comply with complex and evolving regulations related to data privacy and cyber security; the ability to successfully manage ongoing organizational changes, including investments in improving systems and processes; disasters or business continuity problems; the impact of Brexit; risks relating to the U.S. 2020 election, including a potential increase in the corporate tax rate; our ability to successfully enhance our billing, collection and other working capital efforts, and thereby increase our free cash flow; the potential impact of the anticipated replacement of LIBOR; the ability of the company to properly identify and manage conflicts of interest; reputational damage, including from association with third parties; reliance on third-party services; the loss of key employees; doing business internationally, including the impact of exchange rates; compliance with extensive government regulation; the risk of sanctions imposed by governments, or changes to associated sanction regulations; our ability to effectively apply technology, data and analytics changes for internal operations, maintaining industry standards and meeting client preferences; changes and developments in the insurance industry or the United States healthcare system, including those related to Medicare; the inability to protect the company's intellectual property rights, or the potential infringement upon the intellectual property rights of others; fluctuations in the company's pension assets and liabilities; the company's capital structure, including indebtedness amounts, the limitations imposed by the covenants in the documents governing such indebtedness and the maintenance of the financial and disclosure controls and procedures of each; the ability of the company to obtain financing on favorable terms or at all; adverse changes in the credit ratings of the company; the impact of recent changes to U.S. tax laws, including on our effective tax rate, and the enactment of additional, or the revision of existing, state, federal, and/or foreign regulatory and tax laws and regulations; U.S. federal income tax consequences to U.S. persons owning at least 10% of the company's shares; changes in accounting principles, estimates or assumptions; fluctuation in revenue against the company's relatively fixed or higher than expected expenses; the laws of Ireland being different from the laws of the United States and potentially affording less protections to the holders of our securities; and the company's holding company structure potentially preventing it from being able to receive dividends or other distributions in needed amounts from our subsidiaries. These factors also include those described under "Risk Factors" in the company's most recent 10-K and 10-Q filings and subsequent filings filed with the SEC, including definitive additional materials, the merger proxy statement and other filings generally applicable to significant transactions and related integrations that are or will be filed with the SEC. Copies are available online at http://www.sec.gov or www.willistowerswatson.com.

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. In light of the significant 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. In light of these risks, uncertainties and assumptions, the forward-looking events discussed in this document may not occur, and we caution you against relying on these forward-looking statements.

Willis Towers Watson Non-GAAP Measures

In order to assist readers of our consolidated financial statements in understanding the core operating results that Willis Towers 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 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 and (9) Free Cash Flow.

The Company believes that these measures are relevant and provide useful information widely used by analysts, investors and other 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-lookingnon-GAAP financial measures to the corresponding U.S. GAAP measures, due to variability 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 quantitative reconciliation of these forward-lookingnon-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 address 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 calculations and the U.S. GAAP measures may be materially different than the non-GAAP measures.
