Consolidated Results

As reported, USD millions, except %

_{¹ The revenue amounts included in this release are presented on a U.S. GAAP basis except where stated otherwise. The segment discussion is on an organic basis.
² Income in Operations, Operating Margin, Net Income and Diluted EPS for the third quarter of 2025 over the prior-year period is not meaningful (NM) given the pre-tax non-cash losses and impairment charges for the third quarter of 2024 relating to the sale of TRANZACT.
³ Refer to "WTW Non-GAAP Measures" below and the Q3-25 Supplemental Slides for recast of historical Non-GAAP measures.}

Revenue was $2.29 billion for the third quarter of 2025, which was flat compared to $2.29 billion for the same period in the prior year due to the sale of TRANZACT. Excluding the impact of foreign currency, revenue decreased 1%. On an organic basis, revenue increased 5%. See Supplemental Segment Information for additional detail on book-of-business settlements and interest income included in revenue.

Net Income for the third quarter of 2025 was $306 million compared to Net Loss of $1.67 billion in the prior-year third quarter. Adjusted EBITDA for the third quarter was $515 million, or 22.5% of revenue, an increase of 8%, compared to Adjusted EBITDA of $479 million, or 20.9% of revenue, in the prior-year third quarter. The U.S. GAAP tax rate for the third quarter was 19.7%, and the adjusted income tax rate for the third quarter used in calculating adjusted diluted earnings per share was 22.4%.

Cash Flow and Capital Allocation

Cash flows from operating activities were $1.0 billion for the nine months ended September 30, 2025, compared to cash flows from operating activities of $913 million for the same prior-year period. Free cash flow for the nine months ended September 30, 2025 and 2024 was $838 million and $724 million, respectively, an increase of $114 million. The increase was primarily due to operating margin expansion and the abatement of remaining Transformation program cash outflows. During the quarter ended September 30, 2025, the Company repurchased 1,848,098 of its outstanding shares for $600 million.

Third Quarter 2025 Segment Highlights

Health, Wealth & Career (“HWC”)

As reported, USD millions, except %

The HWC segment had revenue of $1.26 billion in the third quarter of 2025, a decrease of 5% (6% decrease constant currency and organic growth of 4%) from $1.33 billion in the prior year due to the sale of TRANZACT. Health delivered organic revenue growth, with increases across all regions, partially offset by prior-year book-of-business settlement activity. Wealth generated organic revenue growth from strong levels of Retirement work in Great Britain and North America, as well as growth in our Investments business from new products and client wins. Career revenue growth is largely attributed to strong demand for advisory project work in Europe. A change in compensation survey delivery patterns moved some revenue from this quarter to the fourth quarter. Benefits Delivery & Outsourcing revenue increased due to strong levels of project and core administration work within Europe which was tempered by lower commission revenue in North America.

Operating margins in the HWC segment increased 390 basis points from the prior-year third quarter to 28.6%, primarily due to the sale of TRANZACT. Excluding TRANZACT operating margins increased 100 basis points due to increased operating efficiencies. Please refer to the Supplemental Slides for TRANZACT's standalone historical financial results.

Risk & Broking (“R&B”)

As reported, USD millions, except %

The R&B segment had revenue of $1.01 billion in the third quarter of 2025, an increase of 7% (5% increase constant currency and organic growth of 6%) from $940 million in the prior year. Corporate Risk & Broking’s (CRB) organic revenue growth was primarily driven by new business and revenue recognized from project-based placements within the global specialty businesses, offsetting the negative impact of insurance rate headwinds. Insurance Consulting and Technology (ICT) revenue was flat for the quarter as clients continued to manage spend more cautiously amid ongoing economic uncertainty.

Operating margins in the R&B segment increased 70 basis points from the prior-year third quarter to 18.8%. The increase was driven by operating leverage from strong organic revenue growth and savings from the Transformation program, partially offset by decreased interest income and foreign currency fluctuations.

Select 2025 Financial Considerations

Changes to Non-GAAP financial measures:

• All reported non-GAAP metrics will exclude non-cash net periodic pension and postretirement benefits
• Free cash flow and free cash flow margin will capture cash outflows for capitalized software costs
• Refer to Supplemental Slides for recast of historical Non-GAAP measures
  

Business mix:

• TRANZACT business, which contributed $1.14 to adjusted diluted earnings per share in 2024, is no longer part of the business portfolio following the completion of the TRANZACT sale in the fourth quarter of 2024
• Reinsurance joint venture with Bain Capital expected to be a headwind on adjusted diluted earnings per share of approximately $0.20, which will be partially mitigated by gains from other equity investments, resulting in a net headwind of approximately $0.10 per share at the interest in earnings of associates level

Free cash flow:

• Expect cash outflows in 2025 from the payment of accrued costs related to the Transformation program which concluded in 2024
  

Capital allocation:

• Expect share repurchases of ~$1.5 billion, subject to market conditions and potential capital allocation to organic and inorganic investment opportunities
  

Foreign exchange:

• Expect a foreign currency tailwind on adjusted diluted earnings per share of approximately $0.15 in the fourth quarter of 2025 and approximately $0.10 for the full year 2025 at today's rates
  

Adjusted operating margin outlook:

• ~100 basis points of average annual margin expansion over next 3 years in R&B
• Incremental annual margin expansion at HWC and enterprise levels

The 2025 Financial Considerations above include Non-GAAP financial measures. We do not reconcile forward-looking Non-GAAP measures for reasons explained under "WTW Non-GAAP Measures" below.

WTW Non-GAAP Measures

In order to assist readers of our consolidated financial statements in understanding the core operating results that WTW’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, (9) Free Cash Flow and (10) Free Cash Flow Margin.

We believe that those measures are relevant and provide pertinent 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.

Within the measures referred to as ‘adjusted’, we adjust for significant items which will not be settled in cash, or which we believe to be items that are not core to our current or future operations. Some of these items may not be applicable for the current quarter, however they may be part of our full-year results. Additionally, we have historically adjusted for certain items which are not described below, but for which we may adjust in a future period when applicable. Items applicable to the quarter or full year results, or the comparable periods, include the following:

• Restructuring costs and transaction and transformation – Management believes it is appropriate to adjust for restructuring costs and transaction and transformation when they relate to a specific significant program with a defined set of activities and costs that are not expected to continue beyond a defined period of time, or significant acquisition-related transaction expenses. We believe the adjustment is necessary to present how the Company is performing, both now and in the future when the incurrence of these costs will have concluded.
• Impairment – Adjustment to remove the non-cash goodwill impairment associated with our Benefits, Delivery and Administration (‘BDA’) reporting unit related to the sale of our TRANZACT business.
• Provisions for specified litigation matters – We will include provisions for litigation matters which we believe are not representative of our core business operations. Among other things, we determine this by reference to the amount of the loss (net of insurance and other recovery receivables) and by reference to whether the matter relates to an unusual and complex scenario that is not expected to be repeated as part of our ongoing, ordinary business. These amounts are presented net of insurance and other recovery receivables. See the footnotes to the reconciliation tables below for more specificity on the litigation matter excluded from adjusted results.
• Gains and losses on disposals of operations – Adjustment to remove the gains or losses resulting from disposed operations that have not been classified as discontinued operations.
• Net periodic pension and postretirement benefits – Adjustment to remove the recognition of net periodic pension and postretirement benefits (including pension settlements), other than service costs. We have included this adjustment as applicable in our prior-period disclosures in order to conform to the current-period presentation.
• Tax effect of significant adjustments – Relates to the incremental tax expense or benefit resulting from significant or unusual events including significant statutory tax rate changes enacted in material jurisdictions in which we operate, internal reorganizations of ownership of certain businesses that reduced the investment held by our U.S.-controlled subsidiaries and the recovery of certain refunds or payment of taxes related to businesses in which we no longer participate.

We evaluate our revenue on an as reported (U.S. GAAP), constant currency and organic basis. We believe presenting constant currency and organic information provides valuable supplemental information regarding our comparable results, consistent with how we evaluate our performance internally.

We consider Constant Currency Change, Organic Change, Adjusted Operating Income/Margin, Adjusted EBITDA/Margin, Adjusted Net Income, Adjusted Diluted Earnings Per Share, Adjusted Income Before Taxes, Adjusted Income Taxes/Tax Rate and Free Cash Flow to be important financial measures, which are used to internally evaluate and assess our core operations and to benchmark our operating and liquidity results against our competitors. These non-GAAP measures are important in illustrating what our comparable operating and liquidity results would have been had we not incurred transaction-related and non-recurring items. Reconciliations of these measures are included in the accompanying tables with the following exception: The Company does not reconcile its forward-looking non-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-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 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.

Our non-GAAP measures and their accompanying definitions are presented as follows:

Constant Currency Change – Represents the year-over-year change in revenue excluding the impact of foreign currency fluctuations. To calculate this impact, the prior year local currency results are first translated using the current year monthly average exchange rates. The change is calculated by comparing the prior year revenue, translated at the current year monthly average exchange rates, to the current year as reported revenue, for the same period. We believe constant currency measures provide useful information to investors because they provide transparency to performance by excluding the effects that foreign currency exchange rate fluctuations have on period-over-period comparability given volatility in foreign currency exchange markets.

Organic Change – Excludes the impact of fluctuations in foreign currency exchange rates, as described above and the period-over-period impact of acquisitions and divestitures on current-year revenue. We believe that excluding transaction-related items from our U.S. GAAP financial measures provides useful supplemental information to our investors, and it is important in illustrating what our core operating results would have been had we not included these transaction-related items, since the nature, size and number of these transaction-related items can vary from period to period.

Adjusted Operating Income/Margin – Income/(Loss) from operations adjusted for impairment, amortization, restructuring costs, transaction and transformation and non-recurring items that, in management’s judgment, significantly affect the period-over-period assessment of operating results. Adjusted operating income margin is calculated by dividing adjusted operating income by revenue. We consider adjusted operating income/margin to be important financial measures, which are used internally to evaluate and assess our core operations and to benchmark our operating results against our competitors.

Adjusted EBITDA/Margin – Net Income/(Loss) adjusted for provision for/(benefit from) income taxes, interest expense, impairment, depreciation and amortization, restructuring costs, transaction and transformation, gains and losses on disposals of operations, net periodic pension and postretirement benefits, and non-recurring items that, in management’s judgment, significantly affect the period-over-period assessment of operating results. Adjusted EBITDA Margin is calculated by dividing adjusted EBITDA by revenue. We consider adjusted EBITDA/margin to be important financial measures, which are used internally to evaluate and assess our core operations, to benchmark our operating results against our competitors and to evaluate and measure our performance-based compensation plans.

Adjusted Net Income – Net Income/(Loss) Attributable to WTW adjusted for impairment, amortization, restructuring costs, transaction and transformation, gains and losses on disposals of operations, net periodic pension and postretirement benefits, and non-recurring items that, in management’s judgment, significantly affect the period-over-period assessment of operating results and the related tax effect of those adjustments and the tax effects of internal reorganizations. This measure is used solely for the purpose of calculating adjusted diluted earnings per share.

Adjusted Diluted Earnings Per Share – Adjusted Net Income divided by the weighted-average number of ordinary shares, diluted. Adjusted diluted earnings per share is used to internally evaluate and assess our core operations and to benchmark our operating results against our competitors.

Adjusted Income Before Taxes – Income/(Loss) from operations before income taxes and interest in earnings of associates adjusted for impairment, amortization, restructuring costs, transaction and transformation, gains and losses on disposals of operations, net periodic pension and postretirement benefits, and non-recurring items that, in management’s judgment, significantly affect the period-over-period assessment of operating results. Adjusted income before taxes is used solely for the purpose of calculating the adjusted income tax rate.

Adjusted Income Taxes/Tax Rate – (Provision for)/benefit from income taxes adjusted for taxes on certain items of impairment, amortization, restructuring costs, transaction and transformation, gains and losses on disposals of operations, net periodic pension and postretirement benefits, the tax effects of significant adjustments and non-recurring items that, in management’s judgment, significantly affect the period-over-period assessment of operating results, divided by adjusted income before taxes. Adjusted income taxes is used solely for the purpose of calculating the adjusted income tax rate. Management believes that the adjusted income tax rate presents a rate that is more closely aligned to the rate that we would incur if not for the reduction of pre-tax income for the adjusted items and the tax effects of internal reorganizations, which are not core to our current and future operations.

Free Cash Flow – Cash flows from operating activities less cash used to purchase fixed assets and software. Free Cash Flow is a liquidity measure and is not meant to represent residual cash flow available for discretionary expenditures. Management believes that free cash flow presents the core operating performance and cash-generating capabilities of our business operations. As a result of our change in presentation, free cash flow for the prior period has been adjusted to conform to the current period, which includes the deduction of our capitalized software costs.

Free Cash Flow Margin – Free Cash Flow as a percentage of revenue, which represents how much of revenue would be realized on a cash basis. We consider this measure to be a meaningful metric for tracking cash conversion on a year-over-year basis due to the non-cash nature of our pension income, which is included in our GAAP and Non-GAAP earnings metrics presented herein.

These non-GAAP measures are not defined in the same manner by all companies and may not be comparable to other similarly titled measures of other companies. Non-GAAP measures should be considered in addition to, and not as a substitute for, the information contained within our condensed consolidated financial statements.

Given 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. 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.

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
