WILLIS TOWERS WATSON PLC

We have included in this document ‘forward-looking statements’ within the meaning of Section 27A of the Securities Act of 1933, and Section 21E of the Securities Exchange Act of 1934, which are intended to be covered by the safe harbors created by those laws. These forward-looking statements include information about possible or assumed future results of our operations or certain considerations relating to our future results. All statements, other than statements of historical facts, that address activities, events or developments that we expect or anticipate may occur in the future, including such things as: our outlook; the potential impact of natural or man-made disasters like health pandemics and other world health crises; future capital expenditures; ongoing working capital efforts; future share repurchases; financial results (including our revenue, costs or margins) and the impact of changes to tax laws on our financial results; existing and evolving business strategies; our ability to execute strategic transactions, including both acquisitions and dispositions, including our ability to receive adequate consideration or any earnout proceeds in return for any dispositions or integrate or manage acquired businesses or effect internal reorganizations; incremental risks relating to the transitional arrangements in effect subsequent to our previously-completed sale of TRANZACT; demand for our services and competitive strengths; strategic goals; the benefits of new initiatives; growth of our business and operations; the sustained health of our product, service, transaction, client, and talent assessment and management pipelines; our ability to successfully manage ongoing leadership, organizational and technology changes, including investments in improving systems and processes; our recognition of future impairment charges; and plans and references to future successes, including our future financial and operating results, short-term and long-term financial goals, plans, objectives, expectations and intentions, including with respect to free cash flow generation, adjusted net income, adjusted operating margin and adjusted earnings per share, are forward-looking statements. Also, when we use words such as ‘may’, ‘will’, ‘would’, ‘anticipate’, ‘believe’, ‘estimate’, ‘expect’, ‘intend’, ‘plan’, ‘continues’, ‘seek’, ‘target’, ‘goal’, ‘focus’, ‘probably’, or similar expressions, we are making forward-looking statements. Such statements are based upon the current beliefs and expectations of the Company’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.

A number of risks and uncertainties that could cause actual results to differ materially from the results reflected in these forward-looking statements are identified under ‘Risk Factors’ in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and updated subsequent filings with the SEC. These statements are based on assumptions that may not come true and are subject to significant risks and uncertainties.

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 significant uncertainties inherent in the forward-looking statements, 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 discussed in this document may not occur, and we caution you against unduly relying on these forward-looking statements.
