WILLIS TOWERS WATSON PLC

Evaluation of Disclosure Controls and Procedures

As of September 30, 2026, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Chief Executive Officer (‘CEO’) and the Chief Financial Officer (‘CFO’), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the ‘Exchange Act’). Based upon that evaluation, our management, including the CEO and CFO, concluded that the our disclosure controls and procedures are effective in providing reasonable assurance that the information required to be included in the periodic reports we file or submit under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (2) accumulated and communicated to our management, including the CEO and the CFO, as appropriate, to allow for timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, identified in connection with the evaluation required by Rules 13a-15(d) or 15d-15(d) under the Exchange Act during the quarter ended September 30, 2026 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls

Management, including the CEO and CFO, does not expect that our disclosure controls and procedures will necessarily prevent all errors and all fraud. However, management does expect that the control system provides reasonable assurance that its objectives will be met. A control system, no matter how well designed and operated, cannot provide absolute assurance that the control system’s objectives will be met. In addition, the design of such internal controls must take into account the costs of designing and maintaining such a control system. Certain inherent limitations exist in control systems to make absolute assurances difficult, including the realities that judgments in decision-making can be faulty, that breakdowns can occur because of a simple error or mistake, and that individuals can circumvent controls. The design of any control system is based in part upon existing business conditions and risk assessments. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in business conditions or deterioration in the degree of compliance with policies or procedures. As a result, they may require change or revision. Because of the inherent limitations in a control system, misstatements due to error or fraud may occur and may not be detected. Nevertheless, the disclosure controls and procedures are designed to provide reasonable assurance of achieving their stated objectives, and the CEO and CFO have concluded that the disclosure controls and procedures are effective at a reasonable assurance level.
