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. 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 including those related to acquisitions and dispositions; 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 ability to implement and realize anticipated benefits of any cost-savings initiatives generated from our completed multi-year operational transformation program or other expense savings initiatives; our recognition of future impairment charges; and plans and references to future performance, 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 revenue, adjusted operating margin and adjusted earnings per share, are all forward-looking statements.

•
fluctuation in revenue against our relatively fixed or higher-than-expected expenses;
•
the risk that market downturns can have a significant impact on investments made across our portfolios;
•
the laws of Ireland being different from the laws of the U.S. and potentially affording less protections to the holders of our securities; and
•
our holding company structure potentially preventing us from being able to receive dividends or other distributions in needed amounts from our subsidiaries.

The foregoing list of factors is not exhaustive and new factors may emerge from time to time that could also affect actual performance and results. For more information, please see Part I, Item 1A in our Annual Report on Form 10-K, and our subsequent filings with the SEC. Copies are available online at http://www.sec.gov or www.wtwco.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. Given the significant uncertainties inherent in the forward-looking statements included in this Quarterly Report on Form 10-Q, 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.

WILLIS TOWERS WATSON PUBLIC LIMITED COMPANY

Notes to the Condensed Consolidated Financial Statements

(Tabular amounts in millions of U.S. dollars, except per share data)

(Unaudited)

Note 1 — Nature of Operations

Willis Towers Watson Public Limited Company is a leading global advisory, broking and solutions company that provides data-driven, insight-led solutions in the areas of people, risk and capital. The Company has approximately 49,000 colleagues serving more than 140 countries and markets.

We design and deliver solutions that manage risk, optimize benefits, cultivate talent and expand the power of capital to protect and strengthen institutions and individuals.

Our risk control services include strategic risk consulting (including providing actuarial analysis), a variety of due diligence services, the provision of practical on-site risk control services (such as health and safety or property loss control consulting), and analytical and advisory services (such as hazard modeling and climate risk quantification). We also assist our clients with managing incidents or crises when they occur. These services include contingency planning, security audits and product tampering plans.

We help our clients enhance their business performance by delivering consulting services, technology and solutions that help them anticipate, identify and capitalize on emerging opportunities in human capital management, as well as offer investment advice to help them develop disciplined and efficient strategies to meet their investment goals.

As an insurance broker, we act as an intermediary between our clients and insurance carriers by advising on their risk management requirements, helping them to determine the best means of managing risk and negotiating and placing insurance with insurance carriers through our global distribution network.

We operate a private Medicare marketplace in the U.S. through which, along with our active employee marketplace, we help our clients move to a more sustainable economic model by capping and controlling the costs associated with healthcare benefits.

We are not an insurance company, and therefore we do not underwrite insurable risks for our own account. We help sharpen strategies, enhance organizational resilience, motivate workforces and maximize performance to uncover opportunities for sustainable success.

Note 2 — Basis of Presentation and Recent Accounting Pronouncements

Basis of Presentation

The accompanying unaudited quarterly condensed consolidated financial statements of WTW and our subsidiaries are presented in accordance with the rules and regulations of the SEC for quarterly reports on Form 10-Q and therefore certain footnote disclosures have been condensed or omitted from these financial statements as they are not required for interim reporting under U.S. GAAP. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, which are necessary for a fair presentation of the condensed consolidated financial statements and results for the interim periods. Certain prior-period amounts have been reclassified to conform to the current-period presentation. All intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements should be read together with the Company’s Annual Report on Form 10-K, filed with the SEC on February 25, 2025, and may be accessed via EDGAR on the SEC’s web site at www.sec.gov.

The results of operations for the three and nine months ended September 30, 2025 are not necessarily indicative of the results that can be expected for the entire year. The Company experiences seasonal fluctuations of its revenue. Revenue is typically higher during the Company’s first and fourth quarters due primarily to the timing of broking-related activities. The results reflect certain estimates and assumptions made by management, including those estimates used in calculating acquisition consideration and fair value of tangible and intangible assets and acquisition-related liabilities, professional liability claims, estimated bonuses, valuation of billed and unbilled receivables, and anticipated tax liabilities that affect the amounts reported in the condensed consolidated financial statements and related notes.

Recent Accounting Pronouncements

Not Yet Adopted

In March 2024, the SEC adopted final rules on the enhancement and standardization of climate-related disclosures for investors (the ‘SEC Climate Rules’). The SEC Climate Rules would require disclosure of certain climate-related information, including in the notes to the Company’s financial statements, in registration statements and annual reports on Form 10-K. Following a number of legal

12

challenges, the SEC voluntarily stayed the SEC Climate Rules pending the completion of judicial review of such consolidated petitions to avoid regulatory uncertainty for companies subject to the SEC Climate Rules. The Company is monitoring the outcome of the litigation.

In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expense, which is intended to provide transparency about the components of expenses included in the income statement. This ASU requires public companies to disclose additional information about certain expenses in the notes to the financial statements on a quarterly and annual basis, including purchases of inventory, employee compensation, depreciation, intangible asset amortization and depletion for each income statement line item that contains those expenses. The ASU requires a new tabular disclosure format that centralizes expense information and additional qualitative disclosure. The guidance does not change the existing income statement presentation. The annual requirements for this ASU become effective with the Company's Annual Report on Form 10-K for the year ended December 31, 2027, and for its interim periods beginning on January 1, 2028. Early adoption is permitted. The guidance is to be applied prospectively, with the option for retrospective application. The Company currently does not plan to early-adopt this ASU and is assessing the expected impact on its condensed consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which is intended to improve guidance on the measurement of credit losses for accounts receivable and contract assets. This ASU provides an optional practical expedient to assume that current conditions as of the balance sheet date do not change for the remaining life of the assets. The requirements for this ASU become effective for the Company on January 1, 2026. Early adoption is permitted and the guidance is applied prospectively to estimates of expected credit losses on asset balances prepared after the date of adoption. The Company does not intend to early-adopt this ASU and does not expect the ASU to have a material impact on its condensed consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which is intended to clarify and modernize the accounting for costs related to internal-use software. This ASU changes capitalization requirements from being tied to development stages and instead creates a capitalization threshold which is achieved when it is probable the software will be completed for its intended purpose. The annual and interim requirements for this ASU become effective for the Company on January 1, 2028. Early adoption is permitted and may be applied using a prospective, retrospective, or modified transition approach. The Company is assessing all aspects of the ASU, including adoption timing and transition method, and the expected impact on its condensed consolidated financial statements.

Adopted

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information within the income tax rate reconciliation and income taxes paid disclosures. It also includes certain other amendments intended to improve the effectiveness of income tax disclosures. Specifically, this ASU requires a tabular income tax rate reconciliation using both percentages and amounts disaggregated into specific categories with certain reconciling items at or above 5% of the statutory tax, further disaggregated by its nature and/or jurisdiction. Additionally, income taxes paid will be required to be presented by federal, state, local and foreign jurisdictions, including amounts paid to individual jurisdictions representing 5% or more of the total income taxes paid. This ASU became effective for the Company on January 1, 2025, at which time it was adopted. The Company will include the required disclosures within its Annual Report on Form 10-K for the year ended December 31, 2025.

Other Legislation

Pillar Two

On October 8, 2021, the Organisation for Economic Co-operation and Development (‘OECD’) announced an international agreement with more than 140 countries to implement a two-pillar solution to address tax challenges arising from the digitalization of the economy. The agreement introduced rules that would result in the reallocation of certain taxing rights over multinational companies from their home countries to the markets where they have business activities and earn profits, regardless of physical presence (‘Pillar One’) and introduced a global corporate minimum tax of 15% for certain large multinational companies starting in 2024 (‘Pillar Two’). On December 20, 2021, the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting released the Model Global Anti-Base Erosion (‘GloBE’) rules (the ‘OECD Model Rules’) under Pillar Two. On December 12, 2022, E.U. member states reached an agreement to implement Pillar Two and this agreement requires E.U. member states to enact domestic legislation to put Pillar Two into effect. In 2023, many E.U. countries enacted the necessary legislation (based on the OECD Model Rules) to implement Pillar Two in 2024. Ireland, in particular, enacted Pillar Two legislation by signing Finance (No. 2) Bill 2023 into law in December 2023. Other countries and territories have indicated they will introduce Pillar Two legislation beginning in 2025. The Pillar Two minimum tax is treated as a period cost beginning in 2024 and does not have a material impact on the Company's financial results of operations

13

for the periods presented. The Company continues to monitor evolving tax legislation as well as additional guidance to enacted legislation in the jurisdictions in which we operate.

H.R. 1

On July 4, 2025, the ‘Act to provide for reconciliation pursuant to title II of H. Con. Res. 14’ (‘H.R. 1’) was enacted into law and generally becomes effective on January 1, 2026, with certain exceptions. H.R. 1 included numerous changes to existing tax law affecting businesses, including extending and modifying certain key provisions of the Tax Cuts and Jobs Act of 2017, both domestic and international, expanding certain Investment Retirement Account incentives while accelerating the phase-out of others. The Company will continue to evaluate the overall impact of H.R. 1 and related regulations on our operations and tax positions and does not expect H.R. 1 to have a material impact on its financial results of operations.

Note 3 — Acquisitions and Divestitures

The Company completed acquisitions, including acquisitions of assets, and made contributions to interests in associates accounted for under the equity method of accounting, for combined cash payments of $30 million during the nine months ended September 30, 2025. Additionally, the Company disposed of a business and had disposal price and other adjustments to the prior-year sale of TRANZACT resulting in a gain of $40 million for the nine months ended September 30, 2025.

Note 4 — Revenue

Disaggregation of Revenue

The Company reports revenue by segment in Note 5 — Segment Information. The following tables present revenue by service offering and segment, as well as reconciliations to total revenue for the three and nine months ended September 30, 2025 and 2024. Along with reimbursable expenses and other, total revenue by service offering represents our revenue from customer contracts.

Interest and other income is included in segment revenue and total revenue, however it has been presented separately in the above tables because it does not arise directly from contracts with customers. The significant components of interest and other income are as follows for the periods presented above:

Contract Balances

The Company reports accounts receivable, net on the condensed consolidated balance sheets, which includes billed and unbilled receivables and current contract assets. In addition to accounts receivable, net, the Company had the following non-current contract assets and deferred revenue balances at September 30, 2025 and December 31, 2024:

|  | September 30, 2025 |  |  | December 31, 2024 |
Billed receivables, net of allowance for doubtful accounts of $33 million and $36 million |  | $ | 1,538 |  |  | $ | 1,604 |
Unbilled receivables |  |  | 557 |  |  |  | 569 |
Current contract assets |  |  | 94 |  |  |  | 321 |
Accounts receivable, net |  | $ | 2,189 |  |  | $ | 2,494 |
Non-current accounts receivable, net |  | $ | 37 |  |  | $ | 18 |
Deferred revenue |  | $ | 717 |  |  | $ | 732 |

During the three and nine months ended September 30, 2025, revenue of $51 million and $513 million, respectively, was recognized that was reflected as deferred revenue at December 31, 2024. During the three months ended September 30, 2025, revenue of $314 million was recognized that was reflected as deferred revenue at June 30, 2025.

15

During the three and nine months ended September 30, 2025, the Company recognized revenue of $4 million and $5 million, respectively, related to performance obligations satisfied prior to 2025.

Performance Obligations

The Company has contracts for which performance obligations have not been satisfied as of September 30, 2025 or have been partially satisfied as of this date. The following table shows the expected timing for the satisfaction of the remaining performance obligations. This table does not include contract renewals or variable consideration, which was excluded from the transaction prices in accordance with the guidance on constraining estimates of variable consideration.

In addition, in accordance with ASC 606, Revenue From Contracts With Customers (‘ASC 606’), the Company has elected not to disclose the remaining performance obligations when one or both of the following circumstances apply:

•
Performance obligations which are part of a contract that has an original expected duration of less than one year, and
•
Performance obligations satisfied in accordance with ASC 606-10-55-18 (‘right to invoice’).

|  | Remainder of 2025 |  |  | 2026 |  |  | 2027 onward |  |  | Total |
Revenue expected to be recognized on contracts as of September 30, 2025 |  | $ | 179 |  |  | $ | 631 |  |  | $ | 807 |  |  | $ | 1,617 |

Since most of the Company’s contracts are cancellable with less than one year’s notice and have no substantive penalty for cancellation, the majority of the Company’s remaining performance obligations as of September 30, 2025 have been excluded from the table above.

Note 5 — Segment Information

WTW has two reportable operating segments or business areas:

•
Health, Wealth & Career (‘HWC’); and
•
Risk & Broking (‘R&B’).

WTW’s chief operating decision maker (‘CODM’) is its chief executive officer. We determined that the operational data used by the CODM is at the segment level. Management bases strategic goals and decisions for these segments on the data presented below which is used to assess the adequacy of strategic decisions and the methods of achieving these strategies and related financial results. Management evaluates the performance of its segments and allocates resources to them based on net segment operating income performance and prospects on a pre-tax basis.

Under the segment structure and for internal and segment reporting, WTW segment revenue includes commissions and fees, interest and other income. U.S. GAAP revenue also includes amounts that were directly incurred on behalf of our clients and reimbursed by them (reimbursable expenses), which are not included in segment revenue. There is no significant segment revenue derived from transactions between the segments.

Following the adoption of ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (‘ASC 2023-07’), the Company has not presented any individual significant expense categories due to the following factors:

•
The CODM’s review focuses on segment operating income results in total, rather than on individual expenses to arrive at segment operating income. The CODM uses segment operating income to make decisions and allocate resources.
•
The CODM does not regularly review any individual significant expense categories at the segment level. Rather, the segment leaders are tasked with achieving the targeted segment operating income and have discretion to determine how to manage their respective expense categories to achieve the targets set by the CODM.
•
Instead, the CODM routinely reviews budgeted, forecasted and actual expense information at the consolidated level only and not at the individual segment level.

Segment operating income excludes certain costs, including (i) amortization of intangibles; (ii) restructuring costs; (iii) certain transaction and transformation expenses; and (iv) to the extent that the actual expense based upon which allocations are made differs from the forecast/budget amount, a reconciling item will be created between internally-allocated expenses and the actual expenses that we report for U.S. GAAP purposes. Although not reviewed individually by the CODM, amounts included in segment expenses may be determined on both a direct and allocated basis and are related to salaries and benefits, depreciation, corporate overhead charges and other operating expenses, including for occupancy, colleague travel costs, legal, marketing, technology, professional fees and professional liability costs.

16

The Company experiences seasonal fluctuations of its revenue. Revenue is typically higher during the Company’s first and fourth quarters due primarily to the timing of broking-related activities.

The following table presents segment revenue, segment expenses and segment operating income for our reportable segments for the three months ended September 30, 2025 and 2024.

Note 6 — Restructuring Costs

In the fourth quarter of 2024, the Company concluded a three-year ‘Transformation program’ designed to enhance operations, optimize technology and align its real estate footprint to its new ways of working. The program incurred cumulative costs of $1.115 billion and capital expenditures of $130 million, resulting in a total investment of $1.245 billion. Although the Transformation program concluded in 2024, we expect additional cash outflows in 2025 from the settlement of accrued costs.

The main categories of charges were in the following four areas:

•
Real estate rationalization — included costs to align the real estate footprint to the new ways of working (hybrid work) as well as breakage fees and the impairment of ROU assets and other related leasehold assets.
•
Technology modernization — these charges were incurred in moving to common platforms and technologies, including migrating certain platforms and applications to the cloud. This category included the impairment of technology assets that were duplicative or no longer revenue-producing, as well as costs for technology investments that did not qualify for capitalization.
•
Process optimization — these costs were incurred in the right-shoring strategy and automation of our operations, which included optimizing resource deployment and appropriate colleague alignment. These costs included process and organizational design costs, severance and separation-related costs and temporary retention costs.
•
Other — other costs not included above including fees for professional services, other contract terminations not related to the above categories and supplier migration costs.

Certain costs under the Transformation program were accounted for under ASC 420, Exit or Disposal Cost Obligation, and are included as restructuring costs in the condensed consolidated statements of comprehensive income. Restructuring costs were $8 million and $29 million for the three and nine months ended September 30, 2024, respectively. Other costs incurred under the Transformation program are included in transaction and transformation and were $67 million and $272 million during the three and nine months ended September 30, 2024, respectively.

A rollforward of the liability associated with cash-based charges related to restructuring costs associated with the Transformation program, including costs paid and payable following the Transformation program’s conclusion on December 31, 2024, is as follows:

|  | Real estate rationalization |  |  | Technology modernization |  |  | Process optimization |  |  | Other |  |  | Total |

Note 7 — Income Taxes

Provision for income taxes for the three months ended September 30, 2025 was $77 million compared to a benefit from income taxes of $322 million for the three months ended September 30, 2024. Provision for income taxes for the nine months ended September 30, 2025 was $121 million compared to a benefit from income taxes of $248 million for the nine months ended September 30, 2024. The effective tax rates were 19.7% and 12.0% for the three and nine months ended September 30, 2025, respectively, and 16.1% and 15.6% for the three and nine months ended September 30, 2024, respectively. These effective tax rates are calculated using extended values from our condensed consolidated statements of comprehensive income and are therefore more precise tax rates than can be calculated from rounded values. The prior-year effective tax rate for the three months ended September 30, 2024 was lower due to deferred tax benefits recognized on the gross-up to carrying value of net assets to be disposed and a deferred tax benefit of $56 million, net of a $37 million valuation allowance, on the expected tax loss associated with the sale of our TRANZACT business. The current-year effective tax rate for the nine months ended September 30, 2025 is lower due to favorable discrete tax items, primarily related to provision-to-tax return adjustments.

The Company recognizes deferred tax balances related to the undistributed earnings of subsidiaries when it expects that it will recover those undistributed earnings in a taxable manner, such as through receipt of dividends or sale of the investments. Historically, the Company has not provided taxes on cumulative earnings of its subsidiaries that have been reinvested indefinitely. As a result of its plans to restructure or distribute accumulated earnings of certain foreign operations, the Company has recorded an estimate of non-U.S. withholding and state income taxes. However, the Company asserts that the historical cumulative earnings of its other subsidiaries are reinvested indefinitely and therefore does not provide deferred tax liabilities on these amounts.

The Company records valuation allowances against net deferred tax assets based on whether it is more likely than not that the deferred tax assets will be realized. We have liabilities for uncertain tax positions under ASC 740, Income Taxes of $52 million, excluding

19

interest and penalties. The Company believes the outcomes that are reasonably possible within the next 12 months may result in a reduction in the liability for uncertain tax positions of approximately $1 million to $24 million, excluding interest and penalties.

Note 9 — Derivative Financial Instruments

We are exposed to certain foreign currency risks. Where possible, we identify exposures in our business that can be offset internally. Where no natural offset is identified, we may choose to enter into various derivative transactions. These instruments have the effect of reducing our exposure to unfavorable changes in foreign currency rates. The Company’s board of directors reviews and approves policies for managing this risk as summarized below. Additional information regarding our derivative financial instruments can be found in Note 11 — Fair Value Measurements and Investments and Note 17 — Accumulated Other Comprehensive Loss.

Foreign Currency Risk

Certain non-U.S. subsidiaries receive revenue and incur expenses in currencies other than their functional currency, and as a result, the foreign subsidiary’s functional currency revenue and/or expenses will fluctuate as the currency rates change. Additionally, the forecast Pounds sterling expenses of our London brokerage market operations may exceed their Pounds sterling revenue, and the entity with such operations may also hold significant foreign currency asset or liability positions in the condensed consolidated balance sheets. To reduce such variability, we use foreign exchange contracts to hedge against this currency risk.

These derivatives were designated as hedging instruments and at September 30, 2025 and December 31, 2024 had total notional amounts of $141 million and $176 million, respectively, with a net fair value asset of $3 million and a net fair value liability of $2 million, respectively.

At September 30, 2025, the Company estimates, based on current exchange rates, there will be $2 million of net derivative gains on forward exchange rates reclassified from accumulated other comprehensive loss into earnings within the next twelve months as the forecast transactions affect earnings. At September 30, 2025, our longest outstanding maturity was 1.7 years.

The effects of the material derivative instruments that are designated as hedging instruments on the condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2025 and 2024 are below. Amounts pertaining to the ineffective portion of hedging instruments and those excluded from effectiveness testing were immaterial for the three and nine months ended September 30, 2025 and 2024.

The Company engages in intercompany borrowing and lending between subsidiaries, primarily through its in-house banking operations which give rise to foreign exchange exposures. The Company mitigates these risks through the use of short-term foreign currency forward and swap transactions that offset the underlying exposure created when the borrower and lender have different functional currencies. These derivatives are not generally designated as hedging instruments, and at September 30, 2025 and December 31, 2024, we had notional amounts of $737 million and $1.2 billion, respectively, with net fair value liabilities of $3 million for both periods presented. Such derivatives typically mature within three months.

The effects of derivatives that have not been designated as hedging instruments on the condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2025 and 2024 are as follows (see Note 16 — Other Income/(Loss), Net for the net foreign currency impact on the Company’s condensed consolidated statements of comprehensive income which includes the results of the offset of underlying exposures):

Note 11 — Fair Value Measurements and Investments

The Company has categorized its assets and liabilities that are measured at fair value on a recurring and non-recurring basis into a three-level fair value hierarchy, based on the reliability of the inputs used to determine fair value as follows:

•
Level 1: refers to fair values determined based on quoted market prices in active markets for identical assets;
•
Level 2: refers to fair values estimated using observable market-based inputs or unobservable inputs that are corroborated by market data; and
•
Level 3: includes fair values estimated using unobservable inputs that are not corroborated by market data.

The following methods and assumptions were used by the Company in estimating its fair value disclosure for financial instruments:

•
Mutual funds and exchange-traded funds are classified as Level 1 because we use quoted market prices in active markets in determining the fair value of these securities.
•
Commingled funds are not leveled within the fair value hierarchy as the funds are valued at the net value of shares held as reported by the manager of the funds. These funds are not exchange-traded.
•
Hedge funds are not leveled within the fair value hierarchy as the fair values for these investments are estimated based on the net asset values derived from the latest audited financial statements or most recent capital account statements provided by the funds’ investment manager or third-party administrator, as a practical expedient.
•
Market values for our derivative instruments have been used to determine the fair values of forward and option foreign exchange contracts based on estimated amounts the Company would receive or have to pay to terminate the agreements, taking into account observable information about the current foreign currency forward rates. Such financial instruments are classified as Level 2.
•
Contingent consideration payable is classified as Level 3, and we estimate fair value based on the likelihood and timing of achieving the relevant milestones of each arrangement, applying a probability assessment to each of the potential outcomes, which at times includes the use of a Monte Carlo simulation and discounting the probability-weighted payout. Typically, milestones are based on revenue or earnings growth for the acquired business.

The note receivable was settled with the Company on April 30, 2025.

The carrying value of our revolving credit facility approximates its fair value. The fair values above, which exclude accrued interest, are not necessarily indicative of the amounts that the Company would realize upon disposition, nor do they indicate the Company’s intent or ability to dispose of the financial instruments. The fair values of our held-to-maturity securities are considered Level 1 financial instruments as they are based on quoted market prices in active markets. The fair values of our respective senior notes and short-term note receivable are considered Level 2 financial instruments as they are corroborated by observable market data.

Defined Benefit Plans

WTW sponsors both qualified and non-qualified defined benefit pension plans throughout the world. The majority of our plan assets and obligations are in the U.S. and the U.K. We have also included disclosures related to defined benefit plans in certain other countries, including Canada, France, Germany, Switzerland and Ireland. Together, these disclosed funded and unfunded plans represent 98% of WTW’s pension obligations and are disclosed herein.

Employer Contributions to Defined Benefit Pension Plans

The Company did no t make any contributions to its U.S. plans during the nine months ended September 30, 2025 and currently does no t anticipate making contributions over the remainder of the fiscal year. The Company made contributions of $1 million to its U.K. plans for the nine months ended September 30, 2025 and anticipates making additional contributions of $1 million for the remainder of the fiscal year. The Company made contributions of $6 million to its other plans for the nine months ended September 30, 2025 and anticipates making additional contributions of less than $1 million for the remainder of the fiscal year.

Annuity Purchase

In February 2025, the Company’s Willis Towers Watson Pension Plan for U.S. Employees, a qualified pension plan (‘the Plan’), purchased a nonparticipating single premium group annuity contract from a third-party insurance company and irrevocably transferred to that insurance company approximately $423 million of the Plan’s defined benefit pension obligations and related plan assets, thereby reducing the pension obligations and assets of the Plan by this same amount. The group annuity contract was purchased using assets of the Plan and no additional funding contribution was required by the Company. As a result of this transaction, WTW recognized a one-time, non-cash pre-tax pension settlement charge of $82 million in the first quarter of 2025, attributable to the accelerated recognition of accumulated actuarial losses of the Plan.

Defined Contribution Plans

The Company had defined contribution plan expense of $39 million and $120 million during the three and nine months ended September 30, 2025, respectively, and $43 million and $128 million during the three and nine months ended September 30, 2024, respectively.

Note 13 — Leases

The following tables present lease costs recorded on our condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2025 and 2024:

|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Finance lease cost: |  |  |  |  |  |  |  |  |  |  |  |
Amortization of right-of-use assets |  | $ | — |  |  | $ | — |  |  | $ | 1 |  |  | $ | 1 |
Interest on lease liabilities |  |  | 1 |  |  |  | 1 |  |  |  | 1 |  |  |  | 1 |
Operating lease cost |  |  | 29 |  |  |  | 31 |  |  |  | 88 |  |  |  | 102 |
Variable lease cost |  |  | 10 |  |  |  | 11 |  |  |  | 25 |  |  |  | 41 |
Sublease income |  |  | (11 | ) |  |  | (5 | ) |  |  | (24 | ) |  |  | (15 | )
Total lease cost, net |  | $ | 29 |  |  | $ | 38 |  |  | $ | 91 |  |  | $ | 130 |

The total lease cost is recognized in different locations in our condensed consolidated statements of comprehensive income. Amortization of the finance lease ROU assets is included in depreciation, while the interest cost component of these finance leases is included in interest expense. All other costs are included in other operating expenses, with the exception of $4 million and $21 million incurred during the three and nine months ended September 30, 2024, respectively, that were included in restructuring costs (see Note 6 — Restructuring Costs) that primarily related to the acceleration of amortization of certain abandoned ROU assets and the payment of early termination fees.

Note 14 — Commitments and Contingencies

Indemnification Agreements

WTW has various agreements with third parties pursuant to which it may be obligated to indemnify the other party to the agreement with respect to certain matters. Generally, these indemnification provisions are included in contracts arising in the normal course of business and in connection with the purchase and sale of certain businesses, including the completed sale of the TRANZACT business. It is not possible to predict the maximum potential amount of future payments that may become due under these indemnification agreements because of the conditional nature of the Company’s obligations, the limited history of prior indemnification claims, and the unique facts of each particular agreement and each indemnification provision therein (even where such indemnification provisions are subject to a maximum liability limit). As of September 30, 2025, we have not incurred a material loss with respect to the indemnification of such third parties. In addition, as of September 30, 2025, we do not believe that any potential liability that may arise from such indemnity obligations is probable or will be material.

Legal Proceedings

In the ordinary course of business, the Company is subject to various actual and potential claims, lawsuits and other proceedings. Some of the claims, lawsuits and other proceedings seek damages in amounts which could, if assessed, be significant. The Company also receives subpoenas in the ordinary course of business and, from time to time, receives requests for information in connection with governmental investigations.

Errors and omissions claims, lawsuits and other proceedings arising in the ordinary course of business are covered in part by professional indemnity or other appropriate insurance. The terms of this insurance vary by policy year. Regarding self-insured risks, the Company has established provisions which are believed to be adequate in light of current information and legal advice, or, in certain cases, where a range of loss exists, the Company accrues the minimum amount in the range if no amount within the range is a better estimate than any other amount. The Company adjusts such provisions from time to time according to developments. See Note 15 — Supplementary Information for Certain Balance Sheet Accounts for the amounts accrued at September 30, 2025 and December 31, 2024 in the condensed consolidated balance sheets.

On the basis of current information, the Company does not expect that the actual claims, lawsuits and other proceedings to which it is subject, or potential claims, lawsuits and other proceedings relating to matters of which it is aware, will ultimately have a material adverse effect on its financial condition, results of operations or liquidity. Nonetheless, given the large or indeterminate amounts sought in certain of these actions, and the inherent unpredictability of litigation and disputes with insurance companies, it is possible that an adverse outcome or settlement in certain matters could, from time to time, have a material adverse effect on the Company’s results of operations or cash flows in a particular quarterly or annual period.

The Company provides for contingent liabilities based on ASC 450, Contingencies, when it is determined that a liability, inclusive of defense costs, is probable and reasonably estimable. The contingent liabilities recorded are primarily developed actuarially. Litigation

is subject to many factors which are difficult to predict so there can be no assurance that in the event of a material unfavorable result in one or more claims, we will not incur material costs.

Note 18 — Earnings/(Loss) Per Share

Basic and diluted earnings/(loss) per share are calculated by dividing net income/(loss) attributable to WTW by the average number of ordinary shares outstanding during each period. The computation of diluted earnings/(loss) per share reflects the potential dilution that could occur if dilutive securities and other contracts to issue shares were exercised or converted into shares or resulted in the issuance of shares that then shared in the net income of the Company.

At September 30, 2025 and 2024, there were 0.3 million and 0.5 million restricted time-based stock units outstanding, respectively, and 0.6 million restricted performance-based stock units outstanding for both periods presented. The Company had no time-based share options or performance-based share options outstanding at September 30, 2025 and 2024.

Basic and diluted earnings/(loss) per share are as follows:

|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Net income/(loss) attributable to WTW |  | $ | 304 |  |  | $ | (1,675 | ) |  | $ | 870 |  |  | $ | (1,344 | )
Basic average number of shares outstanding |  |  | 98 |  |  |  | 102 |  |  |  | 99 |  |  |  | 103 |
Dilutive effect of potentially issuable shares |  |  | — |  |  |  | — |  |  |  | 1 |  |  |  | — |
Diluted average number of shares outstanding |  |  | 98 |  |  |  | 102 |  |  |  | 100 |  |  |  | 103 |
Basic earnings/(loss) per share |  | $ | 3.12 |  |  | $ | (16.44 | ) |  | $ | 8.80 |  |  | $ | (13.11 | )
Dilutive effect of potentially issuable shares |  |  | (0.01 | ) |  |  | — |  |  |  | (0.06 | ) |  |  | — |
Diluted earnings/(loss) per share |  | $ | 3.11 |  |  | $ | (16.44 | ) |  | $ | 8.74 |  |  | $ | (13.11 | )

There were no anti-dilutive restricted stock units for the three months ended September 30, 2025. For the nine months ended September 30, 2025, 0.1 million restricted stock units were not included in the computation of the dilutive effect of potentially issuable shares because their effect was anti-dilutive. There were no anti-dilutive options for the three and nine months ended

29

September 30, 2025. The dilutive effect of potentially issuable shares was not computed for the three and nine months ended September 30, 2024 as the Company reported a net loss within its condensed consolidated statements of comprehensive income.

Note 20 — Subsequent Event

On October 17, 2025, Trinity Acquisition plc entered into a third amended and restated revolving credit facility (the ‘Third A&R RCF’) for $1.5 billion that will mature on October 17, 2030. The Third A&R RCF supersedes and replaces the Company’s previous $1.5 billion revolving credit facility which was due to expire in October 2026.

Borrowing costs under the Third A&R RCF differ if the borrowing is a ‘base rate’ borrowing or a ‘Term Benchmark’ borrowing, both as defined in the Third A&R RCF, and equal the sum of the relevant benchmark plus a margin based on the Company’s senior unsecured long-term debt rating as described below:

•
For base rate borrowings, the benchmark rate will be the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Effective Rate in effect on such day plus 0.50%, and (c) the term secured overnight financing rate (‘Term SOFR’, as further defined in the Third A&R RCF) plus 1.0%. The margin on the base rate benchmark is 0.00% to 0.375% depending on the Company’s senior unsecured long-term debt rating.
•
For Term Benchmark or Daily Simple Risk-Free Rate (‘RFR’) borrowings, the rate will be the applicable secured overnight financing rate (‘SOFR’, as further defined in the Third A&R RCF) or Daily Simple RFR (as applicable based on the currency of the borrower) plus a margin of 0.75% to 1.375% depending on the Company’s guaranteed unsecured long-term debt rating.

The Third A&R RCF also carries a commitment (unused) fee of 0.065% to 0.15%, which is also based on the Company’s senior unsecured long-term debt rating.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This discussion includes forward-looking statements. See ‘Disclaimer Regarding Forward-looking Statements’ for certain cautionary information regarding forward-looking statements and a list of factors that could cause actual results to differ materially from those predicted in those statements.

This discussion includes references to non-GAAP financial measures as defined in the rules of the SEC. We present such non-GAAP financial measures, specifically, adjusted, constant currency and organic non-GAAP financial measures, as we believe such information is of interest to the investment community because it provides additional meaningful methods of evaluating certain aspects of the Company’s operating performance from period to period on a basis that may not be otherwise apparent under U.S. GAAP, and these provide a measure against which our businesses may be assessed in the future.

See ‘Non-GAAP Financial Measures’ below for further discussion of our adjusted, constant currency and organic non-GAAP financial measures.

Executive Overview

Impact of Market Conditions on Our Business

Typically, our business benefits from regulatory change, political risk or economic uncertainty. Insurance broking generally tracks the economy, but demand for both insurance broking and consulting services usually remains steady during times of uncertainty. We have some businesses, such as our health and benefits and administration businesses, which can be counter cyclical during the early period of a significant economic change.

Within our insurance and brokerage business, due to the cyclical nature of the insurance market and the impact of other market conditions on insurance premiums, commission revenue may vary widely between accounting periods. A period of low or declining premium rates, generally known as a ‘soft’ or ‘softening’ market, generally leads to downward pressure on commission revenue and can have a material adverse impact on our revenue and operating margin. A ‘hard’ or ‘firming’ market, during which premium rates rise, generally has a favorable impact on our revenue and operating margin. Rates, however, vary by geography, industry and client segment. As a result, and due to the global and diverse nature of our business, we view rates in the aggregate. Overall, at the time of filing this Quarterly Report, we are seeing a softening market.

Market conditions in the broking industry in which we operate are generally defined by factors such as the strength of the various geographical economies which we serve around the world, insurance rate movements, and insurance and reinsurance buying patterns of our clients.

The markets for our consulting, technology and solutions, and marketplace services are affected by economic, regulatory and legislative changes, technological developments, and increased competition from established and new competitors. We believe that the primary factors in selecting a human resources or risk management consulting company include reputation, the ability to provide measurable increases to shareholder value and return on investment, global scale, quality of service and the ability to tailor services to clients’ unique needs. In that regard, we are focused on developing and implementing technology, data and analytic solutions for both internal operations and for maintaining industry standards and meeting client preferences. We have made such investments from time to time and may decide, based on perceived business needs, to make investments in the future that may be different from past practice or our current expectations.

With regard to the market for exchanges, we believe that clients base their decisions on a variety of factors that include the role of health care coverage in recruiting/retaining employees and transitioning employees to retirement, the availability of price competitive individual insurance policies, the array of coverage choices available through the exchange provider and its ability to deliver measurable cost savings for corporate clients, and to both execute efficiently and deliver high quality service. Since the individual insurance market for Medicare policies is well-established and a significant portion of corporate employers have already implemented an exchange for their Medicare retirees, growth in this population segment will be derived from public employers and educational and other not-for-profit institutions. This growth may be more episodic in nature. Growth in other population segments is likely to remain low unless a more competitive individual insurance market emerges for these segments.

U.S. and global markets are continuing to experience uncertainty, volatility and disruption as a result of uncertain macroeconomic conditions including tariff actions and uncertainties relating to global trade, fluctuations in currency exchange rates, volatility in debt and equity markets, uncertainty around interest rates, softening consumer confidence and labor markets, the implementation of a broad range of U.S. policy changes, and the ongoing Russia-Ukraine and other geopolitical conflicts and tensions. Although the length and impact of these situations are highly unpredictable, the ongoing uncertainty and volatility of the global economy and capital markets,

which has resulted in persistent inflation and fluctuating interest rates in many of the markets in which we operate, could accelerate recessionary pressures and continue to lead to further market disruptions. Further, in addition to the direct impact of the continuing dynamic tariff environment on our business (which we do not expect to be significant, so long as retaliatory actions do not extend to services), recent U.S. legislation and other U.S. federal government actions continue to create uncertainty for the business as well as accounting and tax matters. Other indirect impacts from changes in tariffs or from legislative or regulatory developments, such as changes in consumer sentiment, trade relations, economic activity, disruption of U.S. federal government operations, willingness to do business with U.S.-listed firms, inflationary pressures and employee distraction, among others, could negatively affect our business, operations and financial condition.

These general economic conditions, including inflation, stagflation, political volatility, costs of labor, cost of capital, interest rates, bank stability, credit availability and tax rates, affect not only the cost of and access to liquidity, but also our costs to run and invest in our business, including our operating and general and administrative expenses, and we have no control or limited ability to control such factors. These general economic conditions impact revenue from customers, as well as income from funds we hold on behalf of customers and pension-related income. While parts of our business could benefit from uncertainty or regulatory change, we may see increased caution in spending on services we provide that are more discretionary in nature or where there are alternatives, such as self-insurance. Other parts of our business, such as M&A-related services, may be adversely impacted when there is lower economic activity or transaction volumes.

If our costs grow significantly in excess of our ability to raise revenue, whether as a result of the foregoing global economic factors or otherwise, our margins and results of operations may be materially and adversely impacted and we may not be able to achieve our strategic and financial objectives.

See Part I, Item 1A ‘Risk Factors’ in our Annual Report on Form 10-K, filed with the SEC on February 25, 2025, for a discussion of risks that may affect, among other things, our growth relative to expectation and our ability to achieve our objectives.

Consolidated Revenue

Revenue for both the three months ended September 30, 2025 and 2024 was $2.3 billion, a decrease of $1 million on an as-reported basis. Adjusting for the impacts of foreign currency and acquisitions and disposals, our organic revenue growth was 5% for the three months ended September 30, 2025. Revenue for the nine months ended September 30, 2025 was $6.8 billion, compared to $6.9 billion for the nine months ended September 30, 2024, a decrease of $123 million, or 2%, on an as-reported basis. Adjusting for the impacts of foreign currency and acquisitions and disposals, our organic revenue growth was 5% for the nine months ended September 30, 2025. The decreases in as-reported revenue were due primarily to the sale of our TRANZACT business on December 31, 2024. The increases in organic revenue were driven by strong performances in both segments. For additional information, please see the section entitled ‘Segment Revenue and Segment Operating Income’ elsewhere within this Item 2 of this Quarterly Report on Form 10-Q.

Our revenue can be materially impacted by changes in currency conversions, which can fluctuate significantly over the course of a calendar year. For the three months ended September 30, 2025, currency translation increased our consolidated revenue by $32 million. The primary currencies driving this change were the Euro and Pound Sterling. For the nine months ended September 30, 2025, currency translation increased our consolidated revenue by $26 million. The primary currencies driving this change were the Pound Sterling and Euro.

The following table details our top five markets based on the percentage of consolidated revenue (in U.S. dollars) from the countries where work was performed for the nine months ended September 30, 2025. These figures do not represent the currency of the related revenue, which is presented in the next table.

Geographic Region |  | % of Revenue |
United States |  |  | 44 | %
United Kingdom |  |  | 22 | %
France |  |  | 5 | %
Canada |  |  | 3 | %

Definitions of Constant Currency Change and Organic Change are included under the section entitled ‘Non-GAAP Financial Measures’ elsewhere within Item 2 of this Form 10-Q.

Segment Revenue and Segment Operating Income

The segment descriptions below should be read in conjunction with the full descriptions of our businesses contained in Part I, Item 1. ‘Business’, within our Annual Report on Form 10-K, filed with the SEC on February 25, 2025.

Segment revenue excludes amounts that were directly incurred on behalf of our clients and reimbursed by them (reimbursed expenses); however, these amounts are included in consolidated revenue, as required by applicable accounting standards and SEC rules. Segment operating income excludes certain costs, including (i) amortization of intangibles; (ii) restructuring costs; and (iii) certain transaction and transformation expenses, and includes certain expense amounts which may be determined on both a direct and allocated basis. See Note 5 – Segment Information within Part I, Item 1 ‘Financial Statements’ of this Quarterly Report on Form 10-Q for more information about how our segment revenue and segment operating income are calculated and for a reconciliation to our GAAP results.

The Company experiences seasonal fluctuations in its revenue. Revenue is typically higher during the Company’s first and fourth quarters due primarily to the timing of broking-related activities.

For each table presented below, the components of the revenue change may not add due to rounding.

Health, Wealth & Career

The Health, Wealth & Career (‘HWC’) segment provides an array of advice, broking, solutions and technology for employee benefit plans, institutional investors, compensation and career programs, and the employee experience overall. Our portfolio of services supports the interrelated challenges that the management teams of our clients face across human resources and finance.

HWC is the larger of the two segments of the Company. Addressing four key areas, Health, Wealth, Career and Benefits Delivery & Outsourcing, the segment is focused on addressing our clients’ people and risk needs to help them succeed in a global marketplace.

The following table sets forth HWC revenue for the three months ended September 30, 2025 and 2024, and the components of the change in revenue for the three months ended September 30, 2025 from the three months ended September 30, 2024.

Segment operating income |  | $ | 361 |  |  | $ | 329 |  |  |  |  |  |  |  |  |  |  |

HWC segment revenue for both the three months ended September 30, 2025 and 2024 was $1.3 billion. Health delivered organic revenue growth, with increases across all regions, partially offset by the headwind from the prior-year’s 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.

HWC segment operating income for the three months ended September 30, 2025 and 2024 was $361 million and $329 million, respectively. HWC segment operating income increased primarily from operating efficiencies.

The following table sets forth HWC segment revenue for the nine months ended September 30, 2025 and 2024 and the components of the change in revenue for the nine months ended September 30, 2025 from the nine months ended September 30, 2024.

Segment operating income |  | $ | 952 |  |  | $ | 941 |  |  |  |  |  |  |  |  |  |  |

HWC segment revenue for the nine months ended September 30, 2025 and 2024 was $3.6 billion and $3.9 billion, respectively. Health delivered organic revenue growth in all regions, led by double-digit increases across International which benefited from strong new business and geographic expansion coupled with the ongoing appeal of our Global Benefits Management solution. Wealth generated organic revenue growth from higher levels of Retirement work globally, alongside growth in our Investments business. Career reported moderate revenue growth, largely driven by an uptick in advisory work in Europe. Benefits Delivery & Outsourcing increased primarily due to robust project and core administrative work in Europe, although this was partially offset by lower revenue in North America.

HWC segment operating income for the nine months ended September 30, 2025 and 2024 was $952 million and $941 million, respectively. HWC segment operating income increased primarily from operating efficiencies which were partially offset by the prior-year sale of TRANZACT.

Risk & Broking

The Risk & Broking (‘R&B’) segment provides a broad range of risk advice, insurance brokerage and consulting services to clients worldwide ranging from small businesses to multinational corporations. The segment comprises two primary businesses - Corporate Risk & Broking and Insurance Consulting and Technology.

The following table sets forth R&B revenue for the three months ended September 30, 2025 and 2024, and the components of the change in revenue for the three months ended September 30, 2025 from the three months ended September 30, 2024.

Segment operating income |  | $ | 189 |  |  | $ | 170 |  |  |  |  |  |  |  |  |  |  |

R&B segment revenue for the three months ended September 30, 2025 and 2024 was $1.0 billion and $940 million, respectively. Corporate Risk & Broking's 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 revenue was flat for the quarter as clients continued to manage spending more cautiously amid ongoing economic uncertainty.

R&B segment operating income for the three months ended September 30, 2025 and 2024 was $189 million and $170 million, respectively. R&B segment operating income increased due primarily to operating leverage driven by strong organic revenue growth and Transformation program savings, which were partially offset by headwinds from decreased interest income and foreign currency fluctuations.

Segment operating income |  | $ | 637 |  |  | $ | 575 |  |  |  |  |  |  |  |  |  |  |

R&B segment revenue for the nine months ended September 30, 2025 and 2024 was $3.1 billion and $2.9 billion, respectively. Corporate Risk & Broking had organic revenue growth primarily driven by the success of our global lines, with higher levels of new business activity and revenue recognized from project-based placements within the global specialty businesses along with strong client retention across all regions. Insurance Consulting and Technology had organic revenue growth driven primarily by the Technology practice.

R&B segment operating income for the nine months ended September 30, 2025 and 2024 was $637 million and $575 million, respectively. R&B segment operating income increased due primarily to operating leverage driven by strong organic revenue growth and transformation savings which were partially offset by headwinds from decreased interest income and foreign currency fluctuations.

Costs of Providing Services

Total costs of providing services for the three months ended September 30, 2025 were $1.9 billion, compared to $3.1 billion for the three months ended September 30, 2024, a decrease of $1.2 billion, or 39%. Total costs of providing services for the nine months ended September 30, 2025 were $5.6 billion, compared to $7.2 billion for the nine months ended September 30, 2024, a decrease of $1.6 billion, or 23%. See the following discussion for further details.

Salaries and Benefits

Salaries and benefits for both the three months ended September 30, 2025 and 2024 were $1.4 billion, an increase of $17 million or 1%. The increase in the current year is primarily due to higher salary expense, driven by increased colleague headcount and cost-of-living compensation adjustments, and higher share-based compensation and benefit costs, partially offset by lower incentive costs. Salaries and benefits, as a percentage of revenue, represented 62% and 61% for the three months ended September 30, 2025 and 2024, respectively.

Salaries and benefits for the nine months ended September 30, 2025 were $4.2 billion, compared to $4.1 billion for the nine months ended September 30, 2024, an increase of $51 million or 1%. The increase in the current year is primarily due to higher salary expense, driven by increased colleague headcount and cost-of-living compensation adjustments, and higher share-based compensation costs, partially offset by lower incentive costs. Salaries and benefits, as a percentage of revenue, represented 62% and 60% for the nine months ended September 30, 2025 and 2024, respectively.

Other Operating Expenses

Other operating expenses for the three months ended September 30, 2025 were $352 million, compared to $419 million for the three months ended September 30, 2024, a decrease of $67 million or 16%. The decrease was primarily due to lower marketing expenses attributable to the sale of our TRANZACT business on December 31, 2024 and lower professional services costs for the current-year period as compared to the prior-year period.

Other operating expenses for the nine months ended September 30, 2025 were $1.1 billion, compared to $1.3 billion for the nine months ended September 30, 2024, a decrease of $262 million or 20%. The decrease was primarily due to lower marketing expenses attributable to the sale of our TRANZACT business on December 31, 2024, decreased office and technology expenses, and lower professional services and occupancy costs, partially offset by higher non-income-related tax expense for the current year as compared to the prior year.

36

Impairment

Impairment for both the three and nine months ended September 30, 2024 was $1.0 billion. Impairment was attributable to the goodwill impairment associated with our Benefits, Delivery and Administration (‘BDA’) reporting unit related to the sale of our TRANZACT business.

Depreciation

Depreciation for the three months ended September 30, 2025 was $56 million, compared to $60 million for the three months ended September 30, 2024, a decrease of $4 million or 7%. Depreciation for the nine months ended September 30, 2025 was $167 million, compared to $176 million for the nine months ended September 30, 2024, a decrease of $9 million or 5%. These decreases were primarily due to a lower depreciable base of assets resulting from disposals associated with the Company’s Transformation program that concluded in the fourth quarter of 2024 and a lower dollar value of assets placed in service during the past few years.

Amortization

Amortization for the three months ended September 30, 2025 was $47 million, compared to $56 million for the three months ended September 30, 2024, a decrease of $9 million or 16%. Amortization for the nine months ended September 30, 2025 was $144 million, compared to $176 million for the nine months ended September 30, 2024, a decrease of $32 million or 18%. These decreases were due in part to the disposal of intangible assets associated with the sale of our TRANZACT business. Our intangible amortization is generally more heavily weighted to the initial years of the useful lives of the related intangibles, and therefore amortization related to intangible assets has decreased and will continue to decrease over time.

Restructuring Costs

Restructuring costs for the three and nine months ended September 30, 2024 were $8 million and $29 million, respectively, and primarily related to the real estate rationalization component of our completed Transformation program.

Transaction and Transformation

Transaction and transformation costs for the three months ended September 30, 2025 were $2 million, compared to $74 million for the three months ended September 30, 2024, a decrease of $72 million. Transaction and transformation costs for the nine months ended September 30, 2025 were $4 million, compared to $296 million for the nine months ended September 30, 2024, a decrease of $292 million. Transaction and transformation costs in the current year were comprised of transaction-related costs, and costs incurred in the prior year primarily included consulting and compensation costs related to our completed Transformation program.

Income from operations for the three months ended September 30, 2025 was $418 million, compared to a loss of $766 million for the three months ended September 30, 2024, an increase of $1.2 billion. This increase resulted primarily from the current-year absence of impairment expense associated with the prior-year sale of our TRANZACT business, lower transformation and transaction costs due to the completion of our Transformation program during the fourth quarter of 2024, and lower marketing expenses for the current-year period.

Income from operations for the nine months ended September 30, 2025 was $1.2 billion, compared to a loss of $274 million for the nine months ended September 30, 2024, an increase of $1.5 billion. This increase resulted primarily from the current-year absence of impairment expense associated with the prior-year sale of our TRANZACT business, lower transformation and transaction costs due to the completion of our Transformation program during the fourth quarter of 2024, lower marketing expenses and decreased office and technology expenses in the current year, partially offset by lower revenue due to the prior-year sale of our TRANZACT business.

Interest Expense

Interest expense for both the three months ended September 30, 2025 and 2024 was $65 million. Interest expense for the nine months ended September 30, 2025 was $194 million as compared to $197 million for the nine months ended September 30, 2024, a decrease of $3 million or 2%. The year-over-year decrease was primarily due to a lower average level of indebtedness in the current year.

Other Income/(Loss), Net

Other income/(loss), net for the three months ended September 30, 2025 was income of $37 million, compared to a loss of $1.2 billion for the three months ended September 30, 2024, an increase of $1.2 billion. Other income/(loss), net for the nine months ended September 30, 2025 was a loss of $18 million, compared to a loss of $1.1 billion for the nine months ended September 30, 2024, an increase of $1.1 billion. These increases were primarily due to gains on disposals of operations in the current year, as compared to the

37

significant loss on disposal in the prior year, which was attributable to the sale of our TRANZACT business, partially offset by lower pension income, which was a result of a significant pension settlement in the current year.

(Provision for)/Benefit from Income Taxes

Provision for income taxes for the three months ended September 30, 2025 was $77 million, compared to a benefit from income taxes of $322 million for the three months ended September 30, 2024, an increase of $399 million. The effective tax rate was 19.7% for the three months ended September 30, 2025, and 16.1% for the three months ended September 30, 2024. Provision for income taxes for the nine months ended September 30, 2025 was $121 million, compared to a benefit from income taxes of $248 million for the nine months ended September 30, 2024, an increase of $369 million. The effective tax rate was 12.0% for the nine months ended September 30, 2025 and 15.6% for the nine months ended September 30, 2024. These effective tax rates are calculated using extended values from our condensed consolidated statements of comprehensive income and are therefore more precise tax rates than can be calculated from rounded values. The prior-year effective tax rate for the three months ended September 30, 2024 was lower due to deferred tax benefits recognized on the gross-up to carrying value of net assets to be disposed and a deferred tax benefit of $56 million, net of a $37 million valuation allowance, on the expected tax loss associated with the sale of our TRANZACT business. The current-year effective tax rate for the nine months ended September 30, 2025 is lower due to favorable discrete tax items, primarily related to provision-to-tax return adjustments.

Net Income/(Loss) Attributable to WTW

Net income attributable to WTW for the three months ended September 30, 2025 was $304 million, compared to a net loss of $1.7 billion for the three months ended September 30, 2024, an increase of $2.0 billion. This increase resulted primarily from the current-year absence of loss on disposal and impairment expense associated with the sale of our TRANZACT business in the prior-year period, partially offset by higher tax expense due to prior-year tax benefits attributable to the losses associated with the sale.

Net income attributable to WTW for the nine months ended September 30, 2025 was $870 million, compared to a net loss of $1.3 billion for the nine months ended September 30, 2024, an increase of $2.2 billion. This increase resulted primarily from the current-year absence of loss on disposal and impairment expense associated with the sale of our TRANZACT business in the prior-year period, lower transformation and transaction costs due to the completion of our Transformation program during the fourth quarter of 2024, and lower marketing expenses for the current year, partially offset by higher tax expense due to prior-year tax benefits attributable to the losses associated with the TRANZACT sale as well as lower revenue due to the sale.

Liquidity and Capital Resources

Executive Summary

Our principal sources of liquidity are funds generated by operating activities, available cash and cash equivalents and amounts available under our revolving credit facility and any new debt offerings.

There has been significant volatility in financial markets, including occasional declines in equity markets, inflation and changes in interest rates and reduced liquidity on a global basis and we expect this volatility could continue, all of which may impact our access to liquidity.

Based on our current balance sheet and cash flows, current market conditions and information available to us at this time, we believe that WTW has access to sufficient liquidity to meet our cash needs, including debt repayment, for the next twelve months. Including our cash generated from operations, our liquidity also includes all of the borrowing capacity available to draw against our recently-amended and restated $1.5 billion revolving credit facility (see Note 20 — Subsequent Event in Part I, Item 1 ‘Financial Statements’ in this Quarterly Report on Form 10-Q for further information). The use of these funds includes investments in the business for growth, scheduled debt repayments, share repurchases, dividend payments and general corporate purposes. Additionally, under our minority ownership interest in a joint venture with Bain Capital, in connection with which we re-entered the reinsurance broking space during the fourth quarter of 2024, we have an option to acquire a controlling interest in the joint venture in the future. Given the initial funding needs of a start-up venture, we expect to make certain capital contributions from time to time resulting in a reduction to earnings until such time as the joint venture generates sufficient revenue to be profitable.

During the nine months ended September 30, 2025, we repurchased $1.3 billion of our outstanding shares and have authorization to repurchase an additional $1.6 billion under our share repurchase program (as further described below under ‘Share Repurchase Program’). We consider many factors, including market and economic conditions, applicable legal requirements and other business considerations, when considering whether to repurchase shares. Our Share Repurchase Program has no termination date and may be suspended or discontinued at any time.

38

Events that could change the historical cash flow dynamics discussed above include significant changes in operating results, potential future acquisitions or divestitures, material changes in geographic sources of cash, unexpected adverse impacts from litigation or tax or regulatory matters, or future pension funding during periods of severe downturn in the capital markets.

Undistributed Earnings of Foreign Subsidiaries

The Company recognizes deferred tax balances related to the undistributed earnings of subsidiaries when it expects that it will recover those undistributed earnings in a taxable manner, such as through receipt of dividends or sale of the investments.

We continue to have certain subsidiaries whose earnings have not been deemed permanently reinvested and for which we have been accruing estimates of the tax effects of such repatriation. Excluding these certain subsidiaries, we continue to assert that the historical cumulative earnings for the remainder of our subsidiaries have been reinvested indefinitely and therefore do not provide deferred taxes on these amounts. If future events, including material changes in estimates of cash, working capital, long-term investment requirements or additional legislation, necessitate that these earnings be distributed, an additional provision for income and foreign withholding taxes, net of credits, may be necessary. Other potential sources of cash may be through the settlement of intercompany loans or return of capital distributions in a tax-efficient manner.

Cash and Cash Equivalents

Our cash and cash equivalents at September 30, 2025 and December 31, 2024 totaled $1.9 billion. The significant changes in cash from December 31, 2024 to September 30, 2025 were due primarily to $1.0 billion of net cash from operations, receipt of the $750 million earnout related to the 2021 divestiture of Willis Re and $62 million associated with the settlement of a note receivable related to the sale of our Max Matthiessen subsidiary in 2020, partially offset by cash outflows of $1.3 billion of share repurchases, $269 million of dividend payments and $166 million of capital expenditures and capitalized software additions.

Additionally, at both September 30, 2025 and December 31, 2024, we had all of the borrowing capacity available to draw against our $1.5 billion revolving credit facility, which was amended and restated on October 17, 2025 (see Note 20 – Subsequent Event in Part I, Item 1 ‘Financial Statements’ of this Quarterly Report on Form 10-Q for additional information about the new revolving credit facility).

Included within cash and cash equivalents at September 30, 2025 and December 31, 2024 are amounts held for regulatory capital adequacy requirements, including $105 million and $104 million, respectively, within our regulated U.K. entities.

Summarized Condensed Consolidated Cash Flows

Cash Flows From Operating Activities

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 nine months ended September 30, 2024. The $1.0 billion of net cash from operating activities for the nine months ended September 30, 2025 included net income of $877 million and $556 million of favorable non-cash adjustments, partially offset by unfavorable changes in operating assets and liabilities of $429 million. This increase in cash flows

39

from operations as compared to the prior year was primarily driven by operating margin expansion and lower Transformation program residual cash outflows.

The $913 million of net cash from operating activities for the nine months ended September 30, 2024 included $2.4 billion of favorable non-cash adjustments, partially offset by a net loss of $1.3 billion and unfavorable changes in operating assets and liabilities of $139 million.

Cash Flows From/(Used In) Investing Activities

Cash flows from investing activities for the nine months ended September 30, 2025 were $530 million as compared to cash flows used in investing activities of $230 million for the nine months ended September 30, 2024. The cash flows from investing activities in the current year consisted primarily of net proceeds from sales of operations resulting from divestitures that occurred in prior years. These inflows were partially offset by capital expenditures, including software additions, our net purchases of held-to-maturity and available-for-sale securities and cash and fiduciary fund transfers.

The cash flows used in investing activities for the nine months ended September 30, 2024 consisted primarily of capital expenditures and capitalized software additions.

Cash Flows (Used In)/From Financing Activities

Cash flows used in financing activities for the nine months ended September 30, 2025 were $1.3 billion. The significant financing activities included share repurchases of $1.3 billion and dividend payments of $269 million, partially offset by net proceeds from fiduciary funds held for clients of $343 million.

Cash flows from financing activities for the nine months ended September 30, 2024 were $205 million. The significant financing activities included net proceeds from fiduciary funds held for clients of $934 million and $84 million of net proceeds from the issuance of debt, partially offset by share repurchases of $506 million and dividend payments of $265 million.

Indebtedness

Total debt, total equity, and the capitalization ratios at September 30, 2025 and December 31, 2024 were as follows:

|  | September 30, 2025 |  |  | December 31, 2024 |
|  | ($ in millions) |
Long-term debt |  | $ | 4,763 |  |  | $ | 5,309 |
Current debt |  |  | 550 |  |  |  | — |
Total debt |  | $ | 5,313 |  |  | $ | 5,309 |
Total WTW shareholders’ equity |  | $ | 7,735 |  |  | $ | 7,940 |
Capitalization ratio |  |  | 40.7 | % |  |  | 40.1 | %

At September 30, 2025, our mandatory debt repayments over the next twelve months include $550 million outstanding on our 4.400% senior notes, which will mature during the first quarter of 2026. In addition, our $1.5 billion revolving credit facility, which was set to expire on October 6, 2026, was replaced on October 17, 2025 by our third amended and restated $1.5 billion revolving credit facility (see Note 20 – Subsequent Event in Part I, Item 1 ‘Financial Statements’ of this Quarterly Report on Form 10-Q for further information).

For more information regarding our current and long-term debt, please see ‘Supplemental Guarantor Financial Information’ elsewhere within this Item 2 of this Quarterly Report on Form 10-Q.

At September 30, 2025 and December 31, 2024, we were in compliance with all financial covenants.

40

Fiduciary Funds

As an intermediary, we hold funds, generally in a fiduciary capacity, for the account of third parties, typically as the result of premiums received from clients that are in transit to insurers and claims due to clients that are in transit from insurers. We also hold funds for clients of our benefits account businesses, some of which are invested in open-ended mutual funds as directed by the participant. These fiduciary funds are included in fiduciary assets on our condensed consolidated balance sheets. We present the equal and corresponding fiduciary liabilities related to these fiduciary funds representing amounts or claims due to our clients or premiums due on their behalf to insurers on our condensed consolidated balance sheets.

Fiduciary funds are generally required to be kept in regulated bank accounts subject to guidelines which emphasize capital preservation and liquidity; such funds are not available to service the Company’s debt or for other corporate purposes. Notwithstanding the legal relationships with clients and insurers, the Company is entitled to retain investment income earned on certain of these fiduciary funds in accordance with industry custom and practice and, in some cases, as supported by agreements with insureds.

At September 30, 2025 and December 31, 2024, we had fiduciary funds of $4.0 billion and $3.4 billion, respectively.

Share Repurchase Program

The Company is authorized to repurchase shares, by way of redemption or otherwise, and will consider whether to do so from time to time, based on many factors, including market conditions. There are no expiration dates for our repurchase plans or programs.

On November 20, 2024, the board of directors approved a $1.0 billion increase to the existing share repurchase program. Additionally, on September 16, 2025, the board of directors approved a $1.5 billion increase to the existing share repurchase program. These increases brought the total approved authorization, since the announcement of the program on April 20, 2016, to $11.7 billion.

At September 30, 2025, approximately $1.6 billion remained on the current repurchase authority. The maximum number of shares that could be repurchased based on the closing price of our ordinary shares on September 30, 2025 of $345.45 was 4,752,506.

During the three and nine months ended September 30, 2025, the Company had the following share repurchase activity:

|  |  | Three Months Ended September 30, 2025 |  | Nine Months Ended September 30, 2025
Shares repurchased |  |  | 1,848,098 |  | 4,069,746
Average price per share |  |  | $324.66 |  | $319.43
Aggregate repurchase cost (excluding broker costs) |  |  | $600 million |  | $1.3 billion

Capital Commitments

The Company’s capital expenditures for fixed assets, capitalized software and software for internal use were $166 million during the nine months ended September 30, 2025. The Company estimates that there will be additional such expenditures in the range of $60 million - $85 million during the remainder of 2025. We currently expect cash from operations to adequately provide for these cash needs. There have been no material changes to our capital commitments since December 31, 2024.

Dividends

Total cash dividends of $269 million were paid during the nine months ended September 30, 2025. In August 2025, the board of directors approved a quarterly cash dividend of $0.92 per share ($3.68 per share annualized rate), which was paid on October 15, 2025 to shareholders of record as of September 30, 2025.

Supplemental Guarantor Financial Information

As of September 30, 2025, WTW has issued the following debt securities (the ‘notes’):

a)
Willis North America Inc. (‘Willis North America’) has approximately $4.5 billion senior notes outstanding, of which $1.0 billion were issued on September 10, 2018, $1.0 billion were issued on September 10, 2019, $275 million were issued on May 29, 2020, $750 million were issued on May 19, 2022, $750 million were issued on May 17, 2023 and $750 million were issued on March 5, 2024; and
b)
Trinity Acquisition plc has approximately $825 million senior notes outstanding, of which $275 million were issued on August 15, 2013 and $550 million were issued on March 22, 2016, and a recently-amended and restated $1.5 billion revolving credit facility, on which no balance was outstanding, nor on the prior facility, at September 30, 2025.

41

The following table presents a summary of the entities that issue each note and those wholly-owned subsidiaries of the Company that guarantee each respective note on a joint and several basis as of September 30, 2025. These subsidiaries are all consolidated by Willis Towers Watson plc (the ‘parent company’) and together with the parent company comprise the ‘Obligor group’. On December 16, 2024, TA I Limited, Willis Towers Watson UK Holdings Limited and Willis Netherlands Holdings B.V. ceased to be guarantors of our notes and are no longer part of the Obligor group, following the transfer of their respective properties and assets to other existing guarantors within the Obligor group. Further, Willis Towers Watson UK Holdings Limited was released from its guarantees under our credit agreement. TA I Limited and Willis Netherlands Holdings B.V. are not guarantors under our amended and restated credit agreement (see Note 20 – Subsequent Event in Part I, Item 1 ‘Financial Statements’ of this Quarterly Report on Form 10-Q for further information).

Entity |  | Trinity Acquisition plc Notes |  | Willis North America Inc. Notes
Willis Towers Watson plc |  | Guarantor |  | Guarantor
Trinity Acquisition plc |  | Issuer |  | Guarantor
Willis North America Inc. |  | Guarantor |  | Issuer
Willis Investment UK Holdings Limited |  | Guarantor |  | Guarantor
Willis Group Limited |  | Guarantor |  | Guarantor
Willis Towers Watson Sub Holdings Unlimited Company |  | Guarantor |  | Guarantor

The notes issued by Willis North America and Trinity Acquisition plc:

•
rank equally with all of the issuer’s existing and future unsubordinated and unsecured debt;
•
rank equally with the issuer’s guarantee of all of the existing senior debt of the Company and the other guarantors, including any debt under the Revolving Credit Facility;
•
are senior in right of payment to all of the issuer’s future subordinated debt; and
•
are effectively subordinated to all of the issuer’s secured debt to the extent of the value of the assets securing such debt.

All other subsidiaries of the parent company are non-guarantor subsidiaries (‘the non-guarantor subsidiaries’).

Each member of the Obligor group has only a stockholder’s claim on the assets of the non-guarantor subsidiaries. This stockholder’s claim is junior to the claims that creditors have against those non-guarantor subsidiaries. Holders of the notes will only be creditors of the Obligor group and not creditors of the non-guarantor subsidiaries. As a result, all of the existing and future liabilities of the non-guarantor subsidiaries, including any claims of trade creditors and preferred stockholders, will be structurally senior to the notes. As of and for the periods ended September 30, 2025 and December 31, 2024, the non-guarantor subsidiaries represented substantially all of the total assets and accounted for substantially all of the total revenue of the Company prior to consolidating adjustments. The non-guarantor subsidiaries have other liabilities, including contingent liabilities that may be significant. Each indenture does not contain any limitations on the amount of additional debt that the Obligor group and the non-guarantor subsidiaries may incur. The amounts of this debt could be substantial, and this debt may be debt of the non-guarantor subsidiaries, in which case this debt would be effectively senior in right of payment to the notes.

The notes are obligations exclusively of the Obligor group. Substantially all of the Obligor group’s operations are conducted through its non-guarantor subsidiaries. Therefore, the Obligor group’s ability to service its debt, including the notes, is dependent upon the net cash flows of its non-guarantor subsidiaries and their ability to distribute those net cash flows as dividends, loans or other payments to the Obligor group. Certain laws restrict the ability of these non-guarantor subsidiaries to pay dividends and make loans and advances to the Obligor group. In addition, such non-guarantor subsidiaries may enter into contractual arrangements that limit their ability to pay dividends and make loans and advances to the Obligor group.

Intercompany balances and transactions between members of the Obligor group have been eliminated. All intercompany balances and transactions between the Obligor group and the non-guarantor subsidiaries have been presented in the disclosures below on a net presentation basis, rather than a gross basis, as this better reflects the nature of the intercompany positions and presents the funding or funded position that is to be received or owed. The intercompany balances and transactions between the Obligor group and non-guarantor subsidiaries, presented below, relate to a number of items including loan funding for acquisitions and other purposes, transfers of surplus cash between subsidiary companies, funding provided for working capital purposes, settlement of expense accounts, transactions related to share-based payment arrangements and share issuances, intercompany royalty and related arrangements, intercompany dividends and intercompany interest. At September 30, 2025 and December 31, 2024, the intercompany balances of the Obligor group with non-guarantor subsidiaries were net receivables of $441 million and $1.0 billion, respectively, and net payables of $15.9 billion and $15.1 billion, respectively.

42

No balances or transactions of non-guarantor subsidiaries are presented in the disclosures other than the intercompany items noted above.

Presented below is certain summarized financial information for the Obligor group.

Non-GAAP Financial Measures

In order to assist readers of our condensed consolidated financial statements in understanding the core operating results that WTW’s management uses to evaluate the business and for financial planning purposes, we present the following non-GAAP measures and their most directly comparable U.S. GAAP measure:

Most Directly Comparable U.S. GAAP Measure |  | Non-GAAP Measure
As reported change |  | Constant currency change
As reported change |  | Organic change
Income/(loss) from operations/margin |  | Adjusted operating income/margin
Net income/(loss)/margin |  | Adjusted EBITDA/margin
Net income/(loss) attributable to WTW |  | Adjusted net income
Diluted earnings/(loss) per share |  | Adjusted diluted earnings per share
Income/(loss) from operations before income taxes and interest in earnings of associates |  | Adjusted income before taxes
Provision for income taxes/U.S. GAAP tax rate |  | Adjusted income taxes/tax rate
Net cash from operating activities |  | Free cash flow

The Company believes that these 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 BDA reporting unit related to the sale of our TRANZACT business.

43

•
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.

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.

Constant Currency Change and Organic Change

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.

•
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.

The constant currency and organic change results, and a reconciliation from the reported results for consolidated revenue are included in the ‘Consolidated Revenue’ section within this Form 10-Q. These measures are also reported by segment in the ‘Segment Revenue and Segment Operating Income’ section within this Form 10-Q.

Reconciliations of the as-reported change to the constant currency and organic changes for the three and nine months ended September 30, 2025 from the three and nine months ended September 30, 2024 are as follows. The components of revenue change may not add due to rounding.

Interest income did not contribute to organic change for the three and nine months ended September 30, 2025.

For the three months ended September 30, 2025, our as-reported revenue decreased by $1 million and our organic revenue grew by 5%. For the nine months ended September 30, 2025, our as-reported revenue decreased by $123 million, or 2%, and our organic revenue grew by 5%. These decreases in as-reported revenue were due primarily to the sale of our TRANZACT business on December 31, 2024. The increases in organic revenue were driven by strong performances in both segments. For additional information, please see the section entitled ‘Segment Revenue and Segment Operating Income’ elsewhere within Item 2 of this Quarterly Report on Form 10-Q.

Adjusted Operating Income/Margin

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 operating income is defined as 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.

Reconciliations of income/(loss) from operations to adjusted operating income for the three and nine months ended September 30, 2025 and 2024 are as follows:

Represents a provision related to potential litigation arising out of a structured insurance program originally placed for a client over 15 years ago. The program is of a type and complexity that was highly bespoke to the client and for that reason is unlikely to be exactly replicated elsewhere. Because of this, while we do not believe the potential litigation is material, we believe excluding this matter from adjusted results makes results more comparable from period to period and more representative of our core business operations.

Adjusted operating income increased for the three months ended September 30, 2025 to $467 million, from $414 million for the three months ended September 30, 2024 and increased for the nine months ended September 30, 2025 to $1.4 billion from $1.3 billion for the nine months ended September 30, 2024. These increases resulted primarily from lower marketing expenses and decreased office and technology expenses in the current-year periods, partially offset by lower revenue due to the prior-year sale of our TRANZACT business.

Adjusted EBITDA/Margin

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.

45

Adjusted EBITDA is defined as 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.

Reconciliations of net income/(loss) to adjusted EBITDA for the three and nine months ended September 30, 2025 and 2024 are as follows:

Adjusted EBITDA for the three months ended September 30, 2025 was $515 million, compared to $479 million for the three months ended September 30, 2024, and was $1.5 billion for both the nine months ended September 30, 2025 and 2024. These increases resulted primarily from lower marketing expenses and decreased office and technology expenses in the current-year periods, partially offset by lower revenue due to the prior-year sale of our TRANZACT business.

Adjusted Net Income and Adjusted Diluted Earnings Per Share

Adjusted net income is defined as 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 is defined as 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.

Reconciliations of net income/(loss) attributable to WTW to adjusted diluted earnings per share for the three and nine months ended September 30, 2025 and 2024 are as follows:

(ii)
The tax effect was calculated using an effective tax rate for each item.
(iii)
Per share values and totals may differ due to rounding.

Our adjusted diluted earnings per share increased for both the three and nine months ended September 30, 2025 as compared to the prior year primarily due to a lower weighted-average outstanding share count due to our share repurchase activity over the last year, and lower marketing expenses and decreased office and technology expenses in the current-year periods, partially offset by lower revenue due to the prior-year sale of our TRANZACT business.

Adjusted Income Before Taxes and Adjusted Income Taxes/Tax Rate

Adjusted income before taxes is defined as 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 is defined as the 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

47

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 significant adjustments, which are not core to our current and future operations.

Reconciliations of income/(loss) from operations before income taxes and interest in earnings of associates to adjusted income before taxes and provision for/(benefit from) income taxes to adjusted income taxes for the three and nine months ended September 30, 2025 and 2024 are as follows:

Because of this, while we do not believe the potential litigation is material, we believe excluding this matter from adjusted results makes results more comparable from period to period and more representative of our core business operations.
(ii)
The tax effect was calculated using an effective tax rate for each item.

Our U.S. GAAP tax rates were 19.7% and 16.1% for the three months ended September 30, 2025 and 2024, respectively, and 12.0% and 15.6% for the nine months ended September 30 2025 and 2024, respectively. The prior-year effective tax rate for the three months ended September 30, 2024 was lower due to deferred tax benefits recognized on the gross-up to carrying value of net assets to be disposed and a deferred tax benefit of $56 million, net of a $37 million valuation allowance, on the expected tax loss associated with the sale of our TRANZACT business. The current-year effective tax rate for the nine months ended September 30, 2025 is lower due to favorable discrete tax items, primarily related to provision-to-tax return adjustments.

Our adjusted income tax rates were 22.4% and 19.7% for the three months ended September 30, 2025 and 2024, respectively, and 21.2% and 21.5% for the nine months ended September 30, 2025 and 2024, respectively. The current-year quarter’s adjusted tax rate is higher primarily due to the geographical distribution of profits. The adjusted tax rate for the first nine months ended September 30, 2025 is lower due to favorable discrete items, primarily related to provision-to-tax return adjustments, in comparison to the prior year.

Free Cash Flow

Free cash flow is defined as 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.

48

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.

Management believes that free cash flow presents the core operating performance and cash generating capabilities of our business operations.

Reconciliations of cash flows from operating activities to free cash flow for the nine months ended September 30, 2025 and 2024 are as follows:

|  | Nine Months Ended September 30 |
|  | 2025 |  |  | 2024 |
|  | (in millions) |
Cash flows from operating activities |  | $ | 1,004 |  |  | $ | 913 |
Less: Additions to fixed assets and software |  |  | (166 | ) |  |  | (189 | )
Free cash flow |  | $ | 838 |  |  | $ | 724 |

The increase in free cash flow during the current-year period was primarily driven by operating margin expansion and lower Transformation program residual cash outflows.

Critical Accounting Estimates

There were no material changes from the Critical Accounting Estimates disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 25, 2025.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We have considered changes in our exposure to market risks during the nine months ended September 30, 2025 and have determined that there have been no material changes to our exposure to market risks from those described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 25, 2025. However, we have provided the following information to supplement or update our disclosures on our Form 10-K.

The Company has a global investment policy which is designed to ensure that we maintain diversification of our cash investments throughout the world in order to minimize the risk of loss due to a counterparty failure.

Interest Income on Fiduciary Funds

As described in our Annual Report on Form 10-K, we are exposed to interest rate risk. Specifically, as a result of our operating activities, we receive cash for premiums and claims which we deposit in high-quality bank term deposit and money market funds, on which we earn interest, where permitted. We also hold funds for clients of our benefits accounts businesses. For the benefit funds not invested, cash and cash equivalents are held, on which we earn interest, until the funds are directed by plan participants to either be invested in mutual funds or paid out on their behalf. This interest earned is included in our condensed consolidated financial statements as interest income. These funds are regulated in terms of access and the instruments in which they may be invested, most of which are short-term in maturity. Short-term rates in major currencies began to decrease over the second half of 2024 from end-of-2023 levels. This followed some steep central bank rate increases in 2023. Our increased interest income in 2024 reflected a combination of relatively high-average interest rates over the course of 2024 and some increases in our invested cash balances. Through the third quarter of 2025, although at levels below the same period in 2024, short-term rates have remained largely stable. Significant economic uncertainty prevails at this time, and the timing and magnitude of future central bank rate changes are uncertain. As to be expected, interest income in the future will be a function of the short-term rates we are able to obtain by currency and the cash balances available to invest. Interest income was $42 million and $121 million for the three and nine months ended September 30, 2025, respectively, and $43 million and $130 million for the three and nine months ended September 30, 2024, respectively. At September 30, 2025, we held $3.1 billion of fiduciary funds invested in interest-bearing accounts. If short-term interest rates increased or decreased by 25 basis points, interest earned on these invested fiduciary funds, and therefore our interest income recognized, would increase or decrease by approximately $8 million on an annualized basis.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of September 30, 2025, 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, 2025 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

50

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.

On November 20, 2024, the board of directors approved a $1.0 billion increase to the existing share repurchase program. Additionally, on September 16, 2025, the board of directors approved a $1.5 billion increase to the existing share repurchase program. These increases brought the total approved authorization, since the announcement of the program on April 20, 2016, to $11.7 billion.
