Disclaimer Regarding Forward-looking Statements

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 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.

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 six months ended June 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. Although the litigation remains pending, in March 2025, the SEC voted to end its defense of 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.

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 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 over the next twelve months 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 $22 million during the six months ended June 30, 2025. Additionally, the Company had disposal price and other adjustments to the prior-year sale of TRANZACT resulting in a gain of $14 million for the six months ended June 30, 2025.

Amounts included in Corporate revenue may include eliminations, adjustments to reserves and impacts from hedged revenue transactions.

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 June 30, 2025 and December 31, 2024:

	June 30, 2025		December 31, 2024
Billed receivables, net of allowance for doubtful accounts of $34 million and $36 million	$	1,694	$	1,604
Unbilled receivables		527		569
Current contract assets		143		321
Accounts receivable, net	$	2,364	$	2,494
Non-current accounts receivable, net	$	27	$	18
Deferred revenue	$	765	$	732

During the three and six months ended June 30, 2025, revenue of $116 million and $462 million, respectively, was recognized that was reflected as deferred revenue at December 31, 2024. During the three months ended June 30, 2025, revenue of $302 million was recognized that was reflected as deferred revenue at March 31, 2025.

During the three and six months ended June 30, 2025, the Company recognized revenue of less than $1 million related to performance obligations satisfied prior to 2025.

Performance Obligations

The Company has contracts for which performance obligations have not been satisfied as of June 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 June 30, 2025	$	331	$	583	$	717	$	1,631

15

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 June 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.

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.

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 $3 million and $21 million for the three and six months ended June 30, 2024, respectively. Other costs incurred under the Transformation program are included in transaction and transformation and were $86 million and $205 million during the three and six months ended June 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

Benefit from income taxes for the three months ended June 30, 2025 was $21 million compared to a provision for income taxes of $26 million for the three months ended June 30, 2024. Provision for income taxes was $44 million and $74 million for the six months ended June 30, 2025 and 2024, respectively. The effective tax rates were (6.8)% and 7.1% for the three and six months ended June 30, 2025, respectively, and 15.6% and 18.1% for the three and six months ended June 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 current-year quarter’s effective tax rate is lower primarily due to favorable discrete tax items, which include an adjustment to the tax provision associated with the earnout received from the sale of our Willis Re business, changes in measurement for existing uncertain tax positions and an excess tax benefit on share-based compensation.

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 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 $2 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.

20

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 June 30, 2025 and December 31, 2024 had total notional amounts of $151 million and $176 million, respectively, with a net fair value asset of $7 million and a net fair value liability of $2 million, respectively.

At June 30, 2025, the Company estimates, based on current exchange rates, there will be $4 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 June 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 six months ended June 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 six months ended June 30, 2025 and 2024.

	Gain recognized in OCI (effective element)
	Three Months Ended June 30,				Six Months Ended June 30,

	$	2		$	1	$	2	$	1

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 June 30, 2025 and December 31, 2024, we had notional amounts $879 million and $1.2 billion, respectively, with a net fair value asset of $2 million and a net fair value liability of $3 million, respectively. 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 six months ended June 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.

(iv)See Note 9 — Derivative Financial Instruments for further information on our derivative investments.

(v)Probability weightings are based on our knowledge of the past and planned performance of the acquired entity to which the contingent consideration applies. The fair value weighted-average discount rates used in our material contingent consideration calculations were 11.00% and 13.43% at June 30, 2025 and December 31, 2024, respectively. Using different probability weightings and discount rates could result in an increase or decrease of the contingent consideration payable.

(vi)Consideration due to be paid across multiple years until 2029.

(i)Realized and unrealized losses include accretion and adjustments to contingent consideration liabilities, which are included within Interest expense and Other operating expenses, respectively, on the condensed consolidated statements of comprehensive income.

There were no significant transfers to or from Level 3 in the six months ended June 30, 2025

Held-to-Maturity Securities

During the three months ended June 30, 2025, the Company invested $50 million in debt securities, which it intends to hold to maturity. The following table summarizes the types of holdings and related values:

Held-to-Maturity Securities	Corporate securities
Amortized cost basis	$	50
Allowance for credit losses		—
Net carrying amount		50
Gross unrealized gains		—
Gross unrealized losses		—
Aggregate fair value	$	50

Non-recurring Fair Value Measurement

The Company has assets that may be required to be recorded at fair value on a non-recurring basis. These assets are evaluated when certain triggering events occur (including the planned disposal of a business or a decrease in estimated future cash flows) that indicate their carrying amounts may not be recoverable.

Fair Value Information about Financial Instruments Not Measured at Fair Value

The following tables present our assets and liabilities not measured at fair value on a recurring basis at June 30, 2025 and December 31, 2024:

(i)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 because 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.

Note 12 — Retirement Benefits

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.

Components of Net Periodic Benefit (Income)/Cost for Defined Benefit Pension Plans

The following tables set forth the components of net periodic benefit (income)/cost for the Company’s defined benefit pension plans for the three and six months ended June 30, 2025 and 2024:

Employer Contributions to Defined Benefit Pension Plans

The Company did not make any contributions to its U.S. plans during the six months ended June 30, 2025 and currently does not anticipate making contributions over the remainder of the fiscal year. The Company made contributions of $1 million to its U.K. plans for the six months ended June 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 six months ended June 30, 2025 and anticipates making additional contributions of $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 $41 million and $81 million during the three and six months ended June 30, 2025, respectively, and $42 million and $85 million during the three and six months ended June 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 six months ended June 30, 2025 and 2024:

	Three Months Ended June 30,						Six Months Ended June 30,
	2025			2024			2025			2024
Finance lease cost:
Amortization of right-of-use assets	$	1		$	—		$	1		$	1
Operating lease cost		30			29			59			71
Variable lease cost		5			16			15			30
Sublease income		(7	)		(5	)		(13	)		(10	)
Total lease cost, net	$	29		$	40		$	62		$	92

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 $2 million and $17 million incurred during the three and six months ended June 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 June 30, 2025, we have not incurred a material loss with respect to the indemnification of such third parties. In addition, as of June 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 June 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

26

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.

See Note 9 — Derivative Financial Instruments for additional details regarding the reclassification adjustments for the derivative settlements.

Note 18 — Earnings Per Share

Basic and diluted earnings per share are calculated by dividing net income attributable to WTW by the average number of ordinary shares outstanding during each period. The computation of diluted earnings 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 June 30, 2025 and 2024, there were 0.3 million and 0.5 million restricted time-based stock units outstanding, respectively, and 0.7 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 June 30, 2025 and 2024.

Basic and diluted earnings per share are as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2025			2024			2025			2024
Net income attributable to WTW	$	331		$	141		$	566		$	331
Basic average number of shares outstanding		99			103			100			103
Dilutive effect of potentially issuable shares		1			—			—			1
Diluted average number of shares outstanding		100			103			100			104
Basic earnings per share	$	3.34		$	1.37		$	5.68		$	3.22
Dilutive effect of potentially issuable shares		(0.02	)		(0.01	)		(0.04	)		(0.02	)
Diluted earnings per share	$	3.32		$	1.36		$	5.64		$	3.20

For the three and six months ended June 30, 2025 and 2024, 0.3 million and 0.1 million restricted stock units, respectively, 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 six months ended June 30, 2025 and 2024.

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

Market Conditions

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, we are currently 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 economies in the various geographic regions in 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 what we currently anticipate.

With regard to the market for exchanges, we believe that clients base their decisions on a variety of factors that include the ability of the provider to deliver measurable cost savings for clients, a strong reputation for efficient execution and an innovative service delivery model and platform. Part of the employer-sponsored insurance market has matured and become more fragmented while other segments remain in the entry phase. As these market segments continue to evolve, we may experience growth in intervals, with periods of accelerated expansion balanced by periods of modest growth. In recent years, growth in the market for exchanges has slowed, and this trend may continue.

Risks and Uncertainties of the Economic Environment

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 Middle East conflicts, among other geopolitical 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

31

the 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 creates additional uncertainty, in particular the ‘Act to provide for reconciliation pursuant to title II of H. Con. Res. 14,’ the direct and indirect effects of which are difficult to predict at this time, but are generally expected to include accounting and tax impacts. Other indirect impacts from changes in tariffs or from legislative or regulatory developments, such as changes in consumer sentiment, trade relations, economic activity, willingness to do business with U.S.-listed firms, inflationary pressures and employee distraction, 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 June 30, 2025 and 2024 was $2.3 billion, a decrease of $4 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 June 30, 2025. Revenue for the six months ended June 30, 2025 was $4.5 billion, compared to $4.6 billion for the six months ended June 30, 2024, a decrease of $122 million, or 3%, on an as-reported basis. Adjusting for the impacts of foreign currency and acquisitions and disposals, our organic revenue growth was 5% for the six months ended June 30, 2025.The decreases in as-reported revenue were due primarily to the sale of our TRANZACT business on December 31, 2024. The increase in organic revenue was 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 June 30, 2025, currency translation increased our consolidated revenue by $30 million. The primary currencies driving this change were the Pound Sterling and Euro. For the six months ended June 30, 2025, currency translation decreased our consolidated revenue by $6 million. The primary currency driving this change was the Mexican Peso.

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 six months ended June 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		21	%
France		6	%
Germany		3	%
Canada		2	%

The table below details the approximate percentage of our revenue and expenses by transactional currency for the six months ended June 30, 2025.

Transactional Currency	Revenue			Expenses (i)
U.S. dollars		52	%		47	%
Pounds sterling		13	%		20	%
Euro		18	%		14	%
Other currencies		17	%		19	%

(i)These percentages exclude certain expenses 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. These items include amortization of intangible assets.

The following tables set forth the total revenue for the three and six months ended June 30, 2025 and 2024, and the components of the change in total revenue for the three and six months ended June 30, 2025, as compared to the prior-year periods. The components of the revenue change may not add due to rounding.

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 June 30, 2025 and 2024, and the components of the change in revenue for the three months ended June 30, 2025 from the three months ended June 30, 2024.

						Components of Revenue Change
					As	Less:	Constant	Less:
	Three Months Ended June 30,				Reported	Currency	Currency	Acquisitions/	Organic
	2025		2024		Change	Impact	Change	Divestitures	Change

Total segment revenue	$	1,180	$	1,260	(6)%	1%	(8)%	(12)%	4%
Segment operating income	$	280	$	276

HWC segment revenue for the three months ended June 30, 2025 and 2024 was $1.2 billion and $1.3 billion, respectively. Health delivered organic revenue growth driven by double-digit increases outside North America and solid performance in North America. Wealth generated organic revenue growth from higher levels of Retirement work globally alongside growth in our Investments business from new business wins and product launches. Career had modest revenue growth as healthy demand for advisory project work outside North America was offset by North America client postponement decisions made earlier in the year. Benefits Delivery & Outsourcing revenue was materially flat, as increased project and core administration work within Europe was tempered by lower commission revenue in the Individual Marketplace business compared to the prior year.

HWC segment operating income for the three months ended June 30, 2025 and 2024 was $280 million and $276 million, respectively. HWC segment operating income increased primarily from operating efficiencies, which were partially offset by the prior-year sale of TRANZACT.

34

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

						Components of Revenue Change

Total segment revenue	$	2,345	$	2,596	(10)%	—%	(10)%	(13)%	3%
Segment operating income	$	591	$	612

HWC segment revenue for the six months ended June 30, 2025 and 2024 was $2.3 billion and $2.6 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 in Europe and International, alongside growth in our Investments business from new products and client wins. Career had modest revenue growth as increased advisory work outside of North America was tempered by some postponements amid economic uncertainty. Benefits Delivery & Outsourcing revenue was materially flat, as increased project and core administration work in Europe was offset by lower revenue in North America.

HWC segment operating income for the six months ended June 30, 2025 and 2024 was $591 million and $612 million, respectively. HWC segment operating income decreased primarily due to the prior-year sale of TRANZACT, partially offset by increases attributable to operating efficiencies.

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 June 30, 2025 and 2024, and the components of the change in revenue for the three months ended June 30, 2025 from the three months ended June 30, 2024.

						Components of Revenue Change
					As	Less:	Constant	Less:
	Three Months Ended June 30,				Reported	Currency	Currency	Acquisitions/	Organic

Interest income		23		29
Total segment revenue	$	1,047	$	979	7%	1%	6%	—%	6%
Segment operating income	$	222	$	202

R&B segment revenue for the three months ended June 30, 2025 and 2024 was $1.0 billion and $979 million, respectively. Corporate Risk & Broking had organic revenue growth driven by higher levels of new business activity and strong client retention globally. Insurance Consulting and Technology revenue was flat for the quarter as clients managed spend more cautiously amid ongoing economic uncertainty.

R&B segment operating income for the three months ended June 30, 2025 and 2024 was $222 million and $202 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.

35

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

Interest income		45		57
Total segment revenue	$	2,074	$	1,957	6%	—%	6%	—%	6%
Segment operating income	$	448	$	405

R&B segment revenue for the six months ended June 30, 2025 and 2024 was $2.1 billion and $2.0 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 strong client retention across all regions. Insurance Consulting and Technology had organic revenue growth driven by the Consulting and Technology practices.

R&B segment operating income for the six months ended June 30, 2025 and 2024 was $448 million and $405 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 June 30, 2025 were $1.9 billion, compared to $2.1 billion for the three months ended June 30, 2024, a decrease of $160 million, or 8%. Total costs of providing services for the six months ended June 30, 2025 were $3.7 billion, compared to $4.1 billion for the six months ended June 30, 2024, a decrease of $430 million, or 10%. See the following discussion for further details.

Salaries and Benefits

Salaries and benefits for both the three months ended June 30, 2025 and 2024 were $1.4 billion, an increase of $52 million or 4%. 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 benefit and share-based compensation costs for the period, partially offset by lower incentive costs in the current-year period. Salaries and benefits, as a percentage of revenue, represented 64% and 62% for the three months ended June 30, 2025 and 2024, respectively.

Salaries and benefits for the six months ended June 30, 2025 were $2.8 billion, compared to $2.7 billion for the six months ended June 30, 2024, an increase of $34 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 in the current year, partially offset by lower incentive costs in the current year. Salaries and benefits, as a percentage of revenue, represented 62% and 59% for the six months ended June 30, 2025 and 2024, respectively.

Other Operating Expenses

Other operating expenses for the three months ended June 30, 2025 were $336 million, compared to $439 million for the three months ended June 30, 2024, a decrease of $103 million or 23%. The decrease was primarily due to lower marketing expenses attributable to the sale of our TRANZACT business on December 31, 2024, decreased costs associated with professional liability claims and lower non-income-related tax expense for the current-year period as compared to the prior-year period.

Other operating expenses for the six months ended June 30, 2025 were $701 million, compared to $896 million for the six months ended June 30, 2024, a decrease of $195 million or 22%. The decrease was primarily due to lower marketing expenses attributable to the sale of our TRANZACT business on December 31, 2024, decreased local office expenses and lower costs associated with professional liability claims, partially offset by higher travel and entertainment costs for the current year as compared to the prior year.

Depreciation

Depreciation for both the three months ended June 30, 2025 and 2024 was $57 million. Depreciation for the six months ended June 30, 2025 was $111 million, compared to $116 million for the six months ended June 30, 2024, a decrease of $5 million or 4%. The

36

year-over-year decrease was 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 June 30, 2025 was $49 million, compared to $60 million for the three months ended June 30, 2024, a decrease of $11 million or 18%. Amortization for the six months ended June 30, 2025 was $97 million, compared to $120 million for the six months ended June 30, 2024, a decrease of $23 million or 19%. 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 six months ended June 30, 2024 were $3 million and $21 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 June 30, 2025 were $2 million, compared to $97 million for the three months ended June 30, 2024, a decrease of $95 million. Transaction and transformation costs for the six months ended June 30, 2025 were $2 million, compared to $222 million for the six months ended June 30, 2024, a decrease of $220 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

Income from operations for the three months ended June 30, 2025 was $368 million, compared to $212 million for the three months ended June 30, 2024, an increase of $156 million. This increase resulted primarily from lower marketing expenses, decreased costs associated with professional liability claims and lower transformation and transaction costs due to the completion of our Transformation program during the fourth quarter of 2024, partially offset by higher salary expense and increased benefit and share-based compensation costs for the current-year period.

Income from operations for the six months ended June 30, 2025 was $800 million, compared to $492 million for the six months ended June 30, 2024, an increase of $308 million. This increase resulted primarily from lower transformation and transaction costs due to the completion of our Transformation program during the fourth quarter of 2024, and lower marketing expenses, decreased local office expenses and lower costs associated with professional liability claims in the current year, partially offset by lower revenue due to the prior-year sale of our TRANZACT business.

Interest Expense

Interest expense for the three months ended June 30, 2025 was $64 million, compared to $68 million for the three months ended June 30, 2024, a decrease of $4 million, or 6%. Interest expense for the six months ended June 30, 2025 was $129 million as compared to $132 million for the six months ended June 30, 2024, a decrease of $3 million or 2%. These decreases were 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 June 30, 2025 was income of $9 million, compared to income of $23 million for the three months ended June 30, 2024, a decrease of $14 million. The decrease was due primarily to lower pension income, which was attributable to a significant pension settlement in the current year, and unfavorable favorable foreign currency movement in the current-year period.

Other income/(loss), net for the six months ended June 20, 2025 was a loss of $55 million, compared to income of $49 million for the six months ended June 30, 2024, a decrease of $104 million. The decrease was due primarily to lower pension income, which was attributable to a significant pension settlement in the current year, and unfavorable foreign currency movement in the current year, partially offset by a gain on disposal pertaining to favorable disposal-price adjustments associated with the prior-year sale of our TRANZACT business.

37

Benefit from/(provision for) Income Taxes

Benefit from income taxes for the three months ended June 30, 2025 was $21 million, compared to a provision for income taxes of $26 million for the three months ended June 30, 2024, a decrease of $47 million. The effective tax rate was (6.8)% for the three months ended June 30, 2025, and 15.6% for the three months ended June 30, 2024. Provision for income taxes for the six months ended June 30, 2025 was $44 million, compared to $74 million for the six months ended June 20, 2024, a decrease of $30 million. The effective tax rate was 7.1% for the six months ended June 30, 2025 and 18.1% for the six months ended June 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 current-year quarter’s effective tax rate is lower primarily due to favorable discrete tax items, which include an adjustment to the tax provision associated with the earnout received from the sale of our Willis Re business, changes in measurement for existing uncertain tax positions and an excess tax benefit on share-based compensation.

Net Income Attributable to WTW

Net income attributable to WTW for the three months ended June 30, 2025 was $331 million, compared to $141 million for the three months ended June 30, 2024, an increase of $190 million, or 135%. This increase resulted primarily from lower marketing expenses, decreased transformation and transaction costs due to the completion of our Transformation program during the fourth quarter of 2024, and lower income tax expense, partially offset by higher salary expense and increased benefit and share-based compensation costs for the current-year period.

Net income attributable to WTW for the six months ended June 30, 2025 was $566 million, compared to $331 million for the six months ended June 30, 2024, an increase of $235 million, or 71%. This increase resulted primarily from lower transformation and transaction costs due to the completion of our Transformation program during the fourth quarter of 2024, and lower marketing expenses, decreased local office expenses and lower income tax expense in the current year, partially offset by lower revenue due to the prior-year sale of our TRANZACT business and pension settlement costs in the current year.

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 $1.5 billion revolving credit facility. 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 six months ended June 30, 2025, we repurchased $700 million of our outstanding shares and have authorization to repurchase an additional $742 million 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.

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.

38

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 June 30, 2025 totaled $2.0 billion, compared to $1.9 billion at December 31, 2024. The increase in cash from December 31, 2024 to June 30, 2025 was due primarily to the $750 million earnout related to the 2021 divestiture of Willis Re, $326 million of net cash from operations 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 $700 million of share repurchases, $179 million of dividend payments and $109 million of capital expenditures and capitalized software additions.

Additionally, we had all of the borrowing capacity available to draw against our $1.5 billion revolving credit facility at both June 20, 2025 and December 31, 2024.

Included within cash and cash equivalents at June 30, 2025 and December 31, 2024 are amounts held for regulatory capital adequacy requirements, including $106 million and $104 million, respectively, within our regulated U.K. entities.

Summarized Condensed Consolidated Cash Flows

The following table presents the summarized condensed consolidated cash flow information for the six months ended June 30, 2025 and 2024:

	Six Months Ended June 30,
	2025			2024

(i)The amounts of cash, cash equivalents and restricted cash, their respective classification on the condensed consolidated balance sheets, as well as their respective portions of the increase or decrease in cash, cash equivalents and restricted cash for each of the periods presented, have been included in Note 19 — Supplemental Disclosures of Cash Flow Information within Part I, Item 1 ‘Financial Statements’ within this Quarterly Report on Form 10-Q.

Cash Flows From Operating Activities

Cash flows from operating activities were $326 million for the six months ended June 30, 2025, compared to cash flows from operating activities of $431 million for the six months ended June 30, 2024. The $326 million of net cash from operating activities for the six months ended June 30, 2025 included net income of $571 million and $388 million of favorable non-cash adjustments, partially offset by unfavorable changes in operating assets and liabilities of $633 million. This decrease in cash flows from operations as compared to the prior year was primarily driven by increased compensation and cash tax payments as well as the absence of cash inflows from TRANZACT following its sale on December 31, 2024, partly offset by lower Transformation program spending and operational improvements.

The $431 million of net cash from operating activities for the six months ended June 30, 2024 included net income of $336 million and $335 million of favorable non-cash adjustments, partially offset by unfavorable changes in operating assets and liabilities of $240 million.

Cash Flows From/(Used In) Investing Activities

Cash flows from investing activities for the six months ended June 30, 2025 were $612 million as compared to cash flows used in investing activities of $158 million for the six months ended June 30, 2024. The cash flows from investing activities in the current

39

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, and our net purchases of held-to-maturity and available-for-sale securities. The cash flows used in investing activities in the prior year consisted primarily of capital expenditures, including software additions.

Cash Flows (Used In)/From Financing Activities

Cash flows used in financing activities for the six months ended June 30, 2025 were $800 million. The significant financing activities included share repurchases of $700 million and dividend payments of $179 million, partially offset by net proceeds from fiduciary funds held for clients of $141 million.

Cash flows from financing activities for the six months ended June 30, 2024 were $364 million. The significant financing activities included net proceeds from fiduciary funds held for clients of $783 million and $85 million of net proceeds from the issuance of debt, partially offset by share repurchases of $301 million and dividend payments of $176 million.

Indebtedness

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

	June 30, 2025			December 31, 2024
	($ in millions)
Long-term debt	$	4,762		$	5,309
Current debt		549			—
Total debt	$	5,311		$	5,309
Total WTW shareholders’ equity	$	8,100		$	7,940
Capitalization ratio		39.6	%		40.1	%

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

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 June 30, 2025 and December 31, 2024, we had fiduciary funds of $3.8 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. This increase brought the total approved authorization, since the announcement of the program on April 20, 2016, to $10.2 billion.

40

At June 30, 2025, approximately $742 million 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 June 30, 2025 of $306.50 was 2,420,076.

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

	Three Months Ended June 30, 2025	Six Months Ended June 30, 2025
Shares repurchased	1,614,427	2,221,648
Average price per share	$309.71	$315.08
Aggregate repurchase cost (excluding broker costs)	$500 million	$700 million

Capital Commitments

The Company’s capital expenditures for fixed assets, capitalized software and software for internal use were $109 million during the six months ended June 30, 2025. The Company estimates that there will be additional such expenditures in the range of $115 million - $140 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 $179 million were paid during the six months ended June 30, 2025. In May 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 July 15, 2025 to shareholders of record as of June 30, 2025.

Supplemental Guarantor Financial Information

As of June 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 $1.5 billion revolving credit facility, on which no balance was outstanding at June 30, 2025.

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 June 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. will be released from their guarantees under our credit agreement when they are fully liquidated.

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;

41

•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 June 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 June 30, 2025 and December 31, 2024, the intercompany balances of the Obligor group with non-guarantor subsidiaries were net receivables of $500 million and $1.0 billion, respectively, and net payables of $15.1 billion at both periods.

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 from operations/margin	Adjusted operating income/margin
Net income/margin	Adjusted EBITDA/margin
Net income attributable to WTW	Adjusted net income
Diluted earnings per share	Adjusted diluted earnings per share
Income 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.

•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.

43

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 six months ended June 30, 2025 from the three and six months ended June 30, 2024 are as follows. The components of revenue change may not add due to rounding.

(i)Interest income did not contribute to organic change for the three and six months ended June 30, 2025.

For the three months ended June 30, 2025, our as-reported revenue decreased by $4 million and our organic revenue grew by 5%. For the six months ended June 30, 2025, our as-reported revenue decreased by $122 million, or 3%, 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 from operations adjusted for 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.

44

Reconciliations of income from operations to adjusted operating income for the three and six months ended June 30, 2025 and 2024 are as follows:

	Three Months Ended June 30,						Six Months Ended June 30,

(i)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 June 30, 2025 to $419 million, from $385 million for the three months ended June 30, 2024 and increased for the six months ended June 30, 2025 to $899 million from $868 million for the six months ended June 30, 2024. These increases resulted primarily from lower marketing expenses and decreased local office 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.

Adjusted EBITDA is defined as net income adjusted for provision for income taxes, interest expense, 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.

45

Reconciliations of net income to adjusted EBITDA for the three and six months ended June 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.

Adjusted EBITDA for the three months ended June 30, 2025 was $470 million, compared to $445 million for the three months ended June 30, 2024, and was $1.0 billion for the six months ended June 30, 2025, compared to $991 million for the six months ended June 30, 2024. These increases resulted primarily from lower marketing expenses and decreased local office expenses in the current-year periods, partially offset by lower revenue due to the prior-year sale of our TRANZACT business and higher benefit and share-based compensation costs in the current-year periods.

Adjusted Net Income and Adjusted Diluted Earnings Per Share

Adjusted net income is defined as net income attributable to WTW adjusted for 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.

46

Reconciliations of net income attributable to WTW to adjusted diluted earnings per share for the three and six months ended June 30, 2025 and 2024 are as follows:

(i)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.

(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 six months ended June 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 local office expenses in the current-year periods, partially offset by lower revenue due to the prior-year sale of our TRANZACT business and higher benefit and share-based compensation costs in the current-year periods.

Adjusted Income Before Taxes and Adjusted Income Taxes/Tax Rate

Adjusted income before taxes is defined as income from operations before income taxes and interest in earnings of associates adjusted for 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 income taxes adjusted for taxes on certain items of amortization, restructuring costs, transaction and transformation, gains and losses on disposals of operations, net periodic pension and postretirement benefits, the tax effects of significant adjustments and non-recurring items that, in management’s judgment, significantly affect the period-over-period assessment of operating results, divided by adjusted income before taxes. Adjusted income taxes is used solely for the purpose of calculating the adjusted income tax rate.

47

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 from operations before income taxes and interest in earnings of associates to adjusted income before taxes and provision for income taxes to adjusted income taxes for the three and six months ended June 30, 2025 and 2024 are as follows:

(i)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.

(ii)The tax effect was calculated using an effective tax rate for each item.

Our U.S. GAAP tax rates were (6.8)% and 15.6% for the three months ended June 30, 2025 and 2024, respectively, and 7.1% and 18.1% for the six months ended June 30 2025 and 2024, respectively. The current-year quarter’s effective tax rate is lower primarily due to favorable discrete tax items, which include an adjustment to the tax provision associated with the earnout received from the sale of our Willis Re business, changes in measurement for existing uncertain tax positions and an excess tax benefit on share-based compensation.

Our adjusted income tax rates were 18.0% and 22.4% for the three months ended June 30, 2025 and 2024, respectively, and 20.5% and 22.3% for the six months ended June 30, 2025 and 2024, respectively. The current-year quarter’s adjusted tax rate is lower primarily due to favorable discrete tax items, changes in measurement for existing uncertain tax positions and an excess tax benefit on share-based compensation.

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.

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.

48

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

	Six Months Ended June 30
	2025			2024
	(in millions)
Cash flows from operating activities	$	326		$	431
Less: Additions to fixed assets and software		(109	)		(126	)
Free cash flow	$	217		$	305

The decrease in free cash flow during the current-year period was primarily driven by increased compensation and cash tax payments as well as the absence of cash inflows from TRANZACT following its sale on December 31, 2024, partly offset by lower Transformation program spending and operational improvements.

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 six months ended June 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 second 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 $40 million and $79 million for the three and six months ended June 30, 2025, respectively, and $44 million and $87 million for the three and six months ended June 30, 2024, respectively. At June 30, 2025, we held $2.8 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 $7 million on an annualized basis.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of June 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 June 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.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, we are a party to various lawsuits, arbitrations or mediations that arise in the ordinary course of business. The disclosure called for by Part II, Item 1 regarding our legal proceedings is incorporated by reference herein from Part I, Item 1 Note 14 — Commitments and Contingencies - Legal Proceedings of the notes to the condensed consolidated financial statements in this Form 10-Q for the quarter ended June 30, 2025.

ITEM 1A. RISK FACTORS

There are no material changes from risk factors as previously disclosed in our Annual Report on Form 10-K, filed with the SEC on February 25, 2025. We urge you to read the risk factors contained therein.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

During the six months ended June 30, 2025, no shares were issued by the Company without registration under the Securities Act of 1933, as amended.

(c) Issuer Purchases of Equity Securities

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 these repurchase plans or programs.

On November 20, 2024, the board of directors approved a $1.0 billion increase to the existing share repurchase program. This increase brought the total approved authorization, since the announcement of the program on April 20, 2016, to $10.2 billion.

The following table presents specified information about the Company’s repurchases of its shares in the second quarter of 2025 and the Company’s remaining repurchase authority.

Period	Total number of shares purchased		Average price  paid per share		Total number of shares purchased as part of publicly announced plans or programs		Maximum number of shares that may yet be purchased under the plans or programs
April 1, 2025 through April 30, 2025		540,279	$	314.14		540,279		3,494,224
May 1, 2025 through May 31, 2025		807,216	$	308.99		807,216		2,687,008
June 1, 2025 through June 30, 2025		266,932	$	302.90		266,932		2,420,076
		1,614,427	$	309.71		1,614,427

At June 30, 2025 the maximum number of shares that may yet be purchased under the existing share repurchase plan is 2,420,076, with approximately $742 million remaining on the current open-ended repurchase authority granted by the board. An estimate of the maximum number of shares under the existing authorities was determined using the closing price of our ordinary shares on June 30, 2025 of $306.50.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

None.

ITEM 4. MINE SAFETY DISCLOSURES

Not applicable.

ARTICLE IIGRANT OF TIME-BASED RESTRICTED SHARE UNITS

Section 2.1- Grant of the Time-Based Restricted Share Units

Subject to the terms and conditions of the Plan and the additional terms and conditions set forth in this Agreement and the restrictive covenants set forth in the RCA, the Company hereby grants to the Colleague the number of RSUs specified in a schedule to the Agreement or as stated in the Colleague’s online account with the Company’s designated broker/stock plan administrator. The Colleague agrees that the grant of RSUs pursuant to this Agreement is sufficient consideration for the Colleague entering into the RCA.The Colleague agrees to execute and deliver or electronically accept this Agreement and the RCA within 60 days of the Grant Date. In the event the Colleague fails to execute and deliver or electronically accept the Agreement or the RCA in the manner and within the period specified in this Section 2.1, the Committee may, in its sole discretion, cancel the RSUs.

Section 2.2- RSU Payment

In accordance with Section 7(d)(ii) of the Plan, the Shares to be issued upon vesting and settlement of the RSUs must be fully paid up prior to issuance of such Shares (including, in the interest of clarity, each issuance of Fractional Share Interests) by payment of the Nominal Value per Share. The Committee shall ensure that payment of the Nominal Value for any Shares underlying the RSUs is received by it on behalf of the Colleague at the time the RSUs are settled from a non-Irish Subsidiary or other source and shall establish any procedures or protocols necessary to ensure that payment is timely received.

Section 2.3- Employment or Service Rights

Subject to the terms of the RCA, the rights and obligations of the Colleague under the terms of their Service shall not be affected by their participation in the Plan or any right which they may have to participate in it. The RSUs and the Colleague’s participation in the Plan will not be interpreted to form an employment agreement or service contract with the Company or any Subsidiary or a Designated Associate Company and the terms of any separate employment agreement or service contract to which the Colleague is a party shall remain in effect and will control to the extent that there are any inconsistencies with this Agreement. The Colleague hereby waives any and all rights to compensation or damages in consequence of the termination of Service for any reason whatsoever insofar as those rights arise or may arise from their ceasing

4

to have rights under or be entitled to earn or vest in their RSUs as a result of such termination of Service. If, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, the Colleague shall be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claims.

Section 2.4- Adjustments in RSUs Pursuant to Change of Control or Similar Event, etc.

Subject to Sections 11 and 12 of the Plan, in the event that the outstanding Shares subject to the RSUs are, from time to time, changed into or exchanged for a different number or kind of Shares or other securities, by reason of a share split, spin-off, share or extraordinary cash dividend, share combination or reclassification, recapitalization or merger, Change of Control, or similar event, the Committee shall, in its absolute discretion, substitute or adjust proportionally (i) the number and kind of Shares or securities subject to the RSUs; or (ii) the terms and conditions applicable to the RSUs. An adjustment may have the effect of reducing the price at which Shares may be acquired to less than their Nominal Value (the “Shortfall”), but only if and to the extent that the Committee shall be authorized to capitalize from the reserves of the Company a sum equal to the Shortfall and to apply that sum in paying up that amount on the Shares. Any such adjustment or determination made by the Committee shall be final and binding upon the Colleague, the Company and all other interested persons.

Section 2.5- Tax Withholding

The Colleague acknowledges that, regardless of any action taken by the Employer, the ultimate liability for all Tax-Related Items, is and remains the Colleague’s responsibility and may exceed the amount actually withheld by the Employer. The Colleague further acknowledges that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the RSUs, including, but not limited to, the grant, vesting or settlement of the RSUs, the subsequent sale of Shares acquired pursuant to such settlement and the receipt of any dividends and/or any dividend equivalents; and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the RSUs to reduce or eliminate the Colleague’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Colleague is subject to Tax-Related Items in more than one jurisdiction, the Colleague acknowledges that the Companyand/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, the Colleague agrees to make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items.

In this regard, the Colleague authorizes the Company and/or the Employer, or their respective agents, in their discretion, to satisfy the obligations with regard to all Tax-Related Items by withholding in Shares (including less than a whole Share) to be issued upon settlement of the RSUs, unless the Colleague instead elects, in accordance with the procedures established by the Company, to satisfy the obligations with regard to U.S. Federal Insurance Contribution Act taxes or other Tax-Related Items that become payable in a year prior to the year in which Shares are issued upon settlement of the RSUs and on a date when the Colleague is in the employ of the Employer through withholding from the Colleague’s wages or other cash amounts payable to the Colleague by the Company or the Employer in lieu of withholding in Shares. In the event that such withholding in Shares is problematic under applicable tax or securities law or has materially adverse accounting consequences, by the Colleague’s acceptance of the RSUs, the Colleague authorizes the Company and/or the Employer, or their respective agents, to (i) withhold from the Colleague’s wages or other cash amounts payable to the Colleague from the Company or the Employer, (ii) sell on the Colleague’s behalf a number of Shares (including less than a whole Share) from those Shares issued to the Colleague as the Company determines to be appropriate to generate cash proceeds sufficient

5

to satisfy the obligation for Tax-Related Items, or (iii) utilize any other method of withholding determined by the Company and permitted by applicable laws and the Plan.

The Company may withhold or account for Tax-Related Items by considering statutory withholding rates or other withholding rates, including minimum or maximum applicable rates applicable in the Colleague’s jurisdiction(s). In the event of over-withholding, the Colleague may receive a refund of any over-withheld amount in cash (with no entitlement to the Share equivalent), or if not refunded, the Colleague may seek a refund from the local tax authorities. In the event of under-withholding, the Colleague may be required to pay any additional Tax-Related Items directly to the applicable tax authority or to the Company and/or the Employer. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Colleague is deemed to have been issued the full number of Shares subject to the vested RSUs, notwithstanding that a number of Shares are held back solely for the purpose of paying the Tax-Related Items.

Finally, the Colleague agrees to pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the Colleague’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if the Colleague fails to comply with the Colleague’s obligations in connection with the Tax-Related Items.

Section 2.6- Dividend Equivalents

On each date that a cash dividend is paid to holders of Shares from the Grant Date through the date immediately prior to the date the RSUs are settled, an amount (the “Dividend Equivalent Amount”) equal to the cash dividend that is paid on each Share, multiplied by the total number of RSUs (including RSUs over Fractional Share Interests) and any Dividend Equivalent Units (as defined below) that remain unvested and outstanding as of the dividend payment record date, will be credited to the Colleague, and such credited amount will be converted into an additional number of RSUs (including RSUs over Fractional Share Interests resulting from the foregoing calculation) determined by dividing the Dividend Equivalent Amount by the Fair Market Value of a Share on the date of the dividend payment (“Dividend Equivalent Units”). Dividend Equivalent Units will be subject to the same conditions as the underlying RSUs with respect to which Dividend Equivalent Units were credited, including without limitation, the provisions governing time and form of settlement applicable to the underlying RSUs. Unless expressly provided otherwise, as used elsewhere in this Agreement, references to RSUs in this Agreement shall also include Dividend Equivalent Units that have been credited to the Colleague pursuant to this Section 2.6.

Section 2.7- Clawback / Repayment

The RSUs (and any Shares or other payments resulting from settlement thereof or proceeds therefrom) shall be subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to facilitate compliance with (i) any clawback, forfeiture or other similar policy adopted by the Committee or the Board as in effect at the time the RSU award is granted, including, for the avoidance of doubt, the Company’s Compensation Recoupment Policy, effective November 28, 2023, or as may be adopted thereafter as the Committee determines necessary, appropriate or advisable in view of applicable laws, governance considerations or industry best practices; and/or (ii) applicable laws. Further, to the extent that the Colleague receives any amount in excess of the amount that the Colleague should otherwise have received under the terms of the RSU award for any reason (including, without limitation, by reason of a financial restatement, mistake in calculations or other administrative error), the Colleague shall be required to repay any such excess amount to the Company. For purposes of the foregoing, the Colleague expressly and explicitly authorizes the Company to issue instructions, on the Colleague’s behalf, to any brokerage firm and/or third-party administrator engaged by the Company to hold any Shares and other

6

amounts acquired pursuant to the RSUs to re-convey, transfer or otherwise return such Shares and/or other amounts to the Company upon the Company’s enforcement of this Section 2.7.

(b)Except as otherwise provided in this Section 3.1 or the terms of the Colleague’s employment, retention or similar agreement, in the event of the Colleague’s termination of Service prior to a Vesting Date, any RSUs that are unvested as of the Termination Date shall be forfeited immediately as of the Termination Date by the Colleague.

(c)In the event of the Colleague’s termination of Service after the first anniversary of the Grant Date and prior to a Vesting Date due to a Qualifying Retirement, any RSUs that are unvested as of the Termination Date shall continue to vest on the original Vesting Dates that occur following the Termination Date, subject to the Colleague’s compliance with the restrictive covenants legally applicable to the Colleague and other obligations contemplated under Section 6.2 of Article VI of this Agreement, as determined in the sole discretion of the Committee. If the Committee determines in its sole discretion that the Colleague has violated the restrictive covenants and other obligations under Section 6.2 of Article VI of this Agreement, any RSUs that are unvested as of the date of the Committee’s determination shall be forfeited immediately. For the avoidance of any doubt, the provisions of this Section 3.1(c) shall prevail over the provisions of Section 3.1 (e).

(d)In the event the RSUs are assumed or otherwise substituted or replaced by the successor corporation or an affiliate thereof in connection with a Change of Control and the Colleague’s Service is terminated (i) by the successor corporation or an affiliate employing the Colleague without Cause or (ii) by the Colleague for Good Reason, in each case, within the 24-month period commencing on the effective date of a Change of Control, all unvested RSUs shall vest as of the Termination Date.

(e)In the event of the Colleague’s (i) termination of Service without Cause by the Employer or (ii) termination of Service by the Colleague for Good Reason, in each case, after the first anniversary of the Grant Date and prior to the effective date of a Change of Control or after the 24-month period commencing on the effective date of a Change of Control, any RSUs that are unvested as of the Termination Date shall be forfeited automatically by the Colleague unless the Committee, in its sole discretion, approves the continued vesting on the original Vesting Dates that occur following the Termination Date of some or all of the unvested RSUs. The continued vesting benefit provided under this Section 3.1(e) shall be subject to the Colleague’s compliance with the restrictive covenants legally applicable to the Colleague and other obligations contemplated under Article VI of this Agreement, as determined in the sole discretion of the Committee. If no determination is made by the Committee as of the Termination Date, then the RSUs shall, to the extent not then vested, be immediately forfeited by the Colleague.

(f)In the event of the Colleague’s termination of Service as a result of the Colleague’s Permanent Disability or death, all unvested RSUs shall vest as of the Termination Date.

7

(g)In the event the RSUs are not assumed or otherwise substituted or replaced by the successor corporation or an affiliate thereof in connection with a Change of Control, all RSUs that are unvested as of the Change of Control shall vest immediately prior to the effective date of the Change of Control.

(h)Notwithstanding anything to the contrary in Section 3.1, no RSUs shall vest prior to the first anniversary of the Grant Date (i) except in the case of the Colleague’s termination of Service resulting from death or Permanent Disability or in connection with a Change of Control, or (ii) unless the Committee, in its sole discretion, determines that the RSUs shall be sourced from the Unrestricted Pool.

(i)Except as otherwise provided in Section 3.1(j), RSUs that become vested shall be settled in Shares (including, in the interest of clarity, Fractional Share Interests underlying the vested RSUs or that result from the withholding of less than a whole Share pursuant to Section 2.5) on the applicable Vesting Date or, if earlier, upon an accelerated vesting event pursuant to Sections 3.1(d), (f) or (g), or as soon as practicable, but not later than 31 days, thereafter. Notwithstanding the foregoing, a Fractional Share Interest may be paid in cash or rounded to the extent provided in Schedule A for the Colleague’s country or to the extent otherwise determined by the Committee in its sole discretion.

(j)Notwithstanding the foregoing, if the RSUs are considered non-qualified deferred compensation subject to Section 409A of the Code, as determined in the sole discretion of the Company, and the Colleague is a U.S. Taxpayer, RSUs that are no longer subject to a substantial risk of forfeiture, as determined in accordance with Section 409A of the Code, shall be settled, without regard to the vesting schedule set forth above, on the earliest to occur of (i) the applicable Vesting Date, (ii) a “change in control event” within the meaning of U.S. Treas. Reg. § 1.409A-3(i)(5) (a “409A CIC Event”), (iii) a “separation from service” within the meaning of Section 409A of the Code (a “Separation from Service”) that occurs following a 409A CIC Event, provided that if the Colleague is a “specified employee” within the meaning of Section 409A of the Code on the date the Colleague experiences a Separation from Service, then the RSUs shall instead be settled on the first business day of the seventh month following the Colleague’s Separation from Service, to the extent such delayed payment is required in order to avoid a prohibited distribution under Section 409A of the Code, (iv) the Colleague’s death, and (v) the Colleague’s disability, within the meaning of Section 409A of the Code.

Section 3.4- Limitation on Obligations

The Company’s obligation with respect to the RSUs granted hereunder is limited solely to the issuance to the Colleague of Shares within the period when such Shares are due to be issued hereunder, and in no event shall the Company become obligated to pay cash in respect of such obligation.

14

The RSUs shall be subject to any special provisions set forth in Schedule A for the Colleague’s country of residence, if any. If the Colleague relocates to one of the countries included in Schedule A prior to the vesting of the RSUs, the special provisions for such country shall apply to the Colleague, to the extent the Company determines that the application of such provisions is necessary or advisable for legal or administrative reasons. Schedule A constitutes part of this Agreement.

Section 7.15- Insider Trading / Market Abuse Laws

The Colleague acknowledges that, depending on the Colleague or the Colleague’s broker’s country of residence or where the Shares are listed, the Colleague may be subject to insider trading restrictions and/or market abuse laws, which may affect the Colleague’s ability to accept, acquire, sell or otherwise dispose of Shares or rights to Shares (e.g., RSUs) or rights linked to the value of Shares under the Plan during such times as the Colleague is considered to have “inside information” regarding the Company (as defined by the laws or regulations in the applicable jurisdictions of the Colleague’s country). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Colleague placed before the Colleague possessed inside information. Furthermore, the Colleague could be prohibited from (i) disclosing the inside information to any third party (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them otherwise to buy or sell securities. Third parties include fellow employees and consultants. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Colleague acknowledges they are responsible for complying with any applicable restrictions and is encouraged to speak to their personal legal advisor for further details regarding any applicable insider-trading and/or market-abuse laws in the Colleague’s country.

Section 7.16- Foreign Asset/Account Reporting Requirements and Exchange Controls

The Colleague’s country may have certain foreign asset and/or foreign account reporting requirements and exchange controls which may affect the Colleague’s ability to acquire or hold Shares under the Plan or cash received from participating in the Plan (including from any dividends paid on Shares, sale proceeds resulting from the sale of Shares acquired under the Plan) in a brokerage or bank account outside the Colleague’s country. The Colleague may be required to report such accounts, assets or transactions to the tax or other authorities in the Colleague’s country. The Colleague also may be required to repatriate sale proceeds or other funds received as a result of the Colleague’s participation in the Plan to the Colleague’s country through a designated bank or broker within a certain time after receipt. The Colleague acknowledges that it is their responsibility to be compliant with such regulations, and the Colleague should consult their personal legal advisor for any details.

Section 7.17- Waiver

The Colleague acknowledges that a waiver by the Company of breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by the Colleague or any other participant of the Plan.

15

Section 7.18- Counterparts

This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original and all of which together shall constitute one and the same instrument.

Section 7.19 - Code Section 409A

For purposes of United States taxpayers, it is intended that the terms of the RSUs will comply with the provisions of Section 409A of the Code and the Treasury Regulations relating thereto so as not to subject the Colleague to the payment of additional taxes and interest under Section 409A of the Code, and this Agreement will be interpreted, operated and administered in a manner that is consistent with this intent. In furtherance of this intent, the Committee may adopt such amendments to this Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, in each case, without the consent of the Colleague, that the Committee determines are reasonable, necessary or appropriate to comply with the requirements of Section 409A of the Code and related United States Department of Treasury guidance. In that light, the Company, its Subsidiaries and any Designated Associate Companies make no representation or covenant to ensure that the RSUs that are intended to be exempt from, or compliant with, Section 409A of the Code are not so exempt or compliant or for any action taken by the Committee with respect thereto. Nothing in the Agreement shall provide a basis for any person to take action against the Company, its Subsidiaries or its Designated Associate Companies based on matters covered by Section 409A of the Code, including the tax treatment of any Shares or other payments made under the RSUs granted hereunder, and the Company, its Subsidiaries and any Designated Associate Companies shall not under any circumstances have any liability to the Colleague or their estate or any other party for any taxes, penalties or interest due on amounts paid or payable under this Agreement, including taxes, penalties or interest imposed under Section 409A of the Code.

By the Colleague’s execution or electronic acceptance of this Agreement (including the Schedules attached hereto) in the manner specified in the Colleague’s online account with the Company’s designated broker/stock plan administrator, the Colleague and the Company have agreed that the RSUs are granted under and governed by the terms and conditions of the Plan and this Agreement (including the Schedules attached hereto).

(Time-Based Restricted Share Units)

WILLIS TOWERS WATSON PUBLIC LIMITED COMPANY

2012 EQUITY INCENTIVE PLAN, AS AMENDED AND RESTATED

Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Agreement or the Plan.

Terms and Conditions

This Schedule A includes additional terms and conditions that govern the Time-Based Restricted Share Unit Award granted to the Colleague under the Willis Towers Watson Public Limited Company 2012 Equity Incentive Plan, as amended from time to time (the “Plan”) and the applicable time-based Restricted Share Unit Agreement (the “Agreement”) if the Colleague resides in one of the countries listed below. This Schedule A forms part of the Agreement. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Agreement or the Plan.

Notwithstanding Section 1.10 and Section 3.1(c) of the Agreement, if the Company receives a legal opinion that there has been a legal judgment and/or legal development in the Colleague’s jurisdiction that likely would result in the favorable treatment that applies to the RSUs as a result of the Colleague’s retirement or reaching a certain age being unlawful and/or discriminatory, the favorable treatment contemplated under Section 1.10 and Section 3.1(c) shall not apply and Section 3.1 shall apply to the Colleague without giving effect to Section 3.1(c).

Notifications

This Schedule A also includes information based on the securities, exchange control and other laws in effect in the Colleague’s country as of February 2025. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Colleague not rely on the information noted herein as the only source of information relating to the consequences of the Colleague’s participation in the Plan because the information may be out of date at the time the RSUs vest under the Plan.

In addition, the information is general in nature. The Company is not providing the Colleague with any tax advice with respect to the RSUs. The information provided below may not apply to the Colleague’s particular situation, and the Company is not in a position to assure the Colleague of any particular result. Accordingly, the Colleague should seek appropriate professional advice as to how the tax or other laws in the Colleague’s country apply to the Colleague’s situation.

Finally, if the Colleague is a citizen or resident of a country other than the one in which the Colleague is currently residing and/or working, transfers employment and/or residency after the Grant Date, or is considered a resident of another country for local law purposes, the terms and conditions contained herein for the country the Colleague is residing and/or working in at the time of grant may not be applicable to the Colleague, and the Company shall, in its discretion, determine to what extent the terms and conditions contained herein shall be applicable to the Colleague. Similarly, the information contained herein may no longer be applicable in the same manner.

Willis Towers Watson

Global Employee Personal Information Protection Notice

Last Updated: December 2024

1.Introduction

Willis Towers Watson operates as a global business through its affiliated entities (together “the Willis Towers Watson Group”). The Willis Towers Watson Group values the trust of its employees worldwide and is committed to protecting their personal information.

The Willis Towers Watson Group operates in many different countries. Some of these countries have laws related to the collection, use, transfer and disclosure of the personal information of individuals, including our employees. The purpose of this Global Employee Personal Information Protection Notice (the “Notice”) is to give you information about what personal information the Willis Towers Watson Group collects, uses, transfers and discloses, and why.

The Willis Towers Watson Group entity responsible for collecting and processing your personal data is the entity that employs you. The Willis Towers Watson Group may also engage with outside entities to collect information consistent with this Notice. You can check which entity employs you by checking your contract of employment or by asking your usual HR contact. In this Notice, the term "we" or "us" refers to that entity. The information that we collect about you as an employee allows us to administer your benefits and helps to support routine Human Resources and operational processes, contingency planning, and internal talent searches.

2.What Personal Information about you that we collect, and how we collect Your Personal Information

In the course of your employment, we may have collected or will collect information about you and your working relationship with us, your spouse, domestic/civil partner and/or dependents (“Dependents”). We refer to such information as “Personal Information” (also known as Personal Data in the Cayman Islands). For more specific information regarding what Personal Information about you, we may collect, use, transfer and disclose, and the purposes for which it may be collected, used, transferred and disclosed, please see Annex 1 to this Notice. Local employee handbooks, office manuals, works council agreements and notices provided in your local office or on the Willis Towers Watson intranet site may provide additional details or information.

We may also collect additional Personal Information in operating our business and interacting with individuals in the course of our business, including employment. This may at times include “sensitive" information (otherwise known as “special categories of personal information” under the General Data Protection Regulation (“GDPR”), “sensitive data” under the Saudi Arabian Personal Data Protection Law (“PDPL”), “sensitive personal data” under the Cayman Islands Data Protection Law (“DPL”), or “sensitive personal information” under the California Consumer Privacy Act (“CCPA”) and Bermuda’s Personal Information Protection Act 2016 (“PIPA”)), such as data about your ethnic origin; religious beliefs; health records or criminal conviction data; physical or mental health or condition; medical data; commission, or alleged commission of an offense; any proceedings for an offense committed, or alleged to have been committed. Where required by law, we will provide specific data processing information to you regarding how we may process that data and what rights you may have regarding such processing.

B-1

For the United Kingdom only:

Please see Annex 4 to this Notice for our Policy on the processing of Special Categories of Personal Information.

Sources of Personal Information

We normally collect your Personal Information directly from you, for example when you apply for a job with us, when you commence your role, and from time to time throughout your employment when we ask you to provide information. We may be required as a consequence of our relationship with you as your employer, or by law, to collect certain Personal Information about you. Failure to provide this information may prevent or delay the fulfilment of our obligations as an employer. We will inform you at the time your information is collected whether certain information is compulsory and the consequences of the failure to provide such information.

We also collect certain Personal Information about you from other sources, including:

(a)background check information from employment screening agencies or publicly available registers (as allowed by law), or references obtained during recruitment;

(b)publicly available professional profiles on websites or social media (e.g. LinkedIn); and

(c)information about your performance or conduct from other employees, clients, or service providers you work with who may provide feedback about you or participate in performance evaluations or reviews.

3.The Legal Bases and purposes for which we use, transfer, and disclose Your Personal Information

UK and EU data protection laws and other laws around the world, for example the PDPL and the DPA and PIPA require that we only process Personal Information subject to one or more valid legal bases. In such cases our legal basis will be one of the following:

(a)to fulfil our contractual obligations to you in connection with your employment contract with us;

(b)to comply with our legal obligations, for example obtaining proof of your identity to enable us to meet our anti-money laundering obligations, or obtaining proof of your right to work status to enable us to meet relevant obligations;

(c)to comply with our legal obligations to you, for example health and safety obligations that we must comply with as your employer or to a third party (e.g. the taxation authorities);

(d)to meet our legitimate interests, for example to manage our employees effectively, to protect us against theft or other crime, to allow you access to our technology and HR resources, and to conduct analytics that allows us to manage our workforce efficiently and plan recruitment activities. When we process Personal Information to meet our legitimate interests, we put in place robust safeguards to ensure that your privacy is protected and to ensure that our legitimate interests are not overridden by your interests or fundamental rights and freedoms;

(e)where a reasonable person would view that you would not reasonably be expected to request that we cease or not begin to use your personal information and that our use will not prejudice your individual rights;

B-2

(f)to protect your or another person's vital interests, for example by providing your health information to a doctor in a medical emergency;

(g)the processing is necessary for medical purposes and is undertaken by (a) a health professional; or (2) a person who, in the circumstances, owes a duty of confidentiality equivalent to that which would arise if that person were a health professional. (see DPA);

(h)the Personal Information is publicly available information and will be used for a purpose that is consistent with the purpose of its public availability (See PIPA);

(i)the use of the Personal Information is necessary in the context of an individual’s present, or past employment relationship with WTW; or

(j)we may obtain your explicit consent to collect and use certain types of Personal Information when we are required to do so by law (for example, when we process some categories of sensitive personal information or, where required by law, execute a processing which is classified as “profiling”). If we ask for your consent to process your personal information, you may withdraw your consent at any time by contacting privacy@wtwco.com.

The purposes for which we use your Personal Information are explained in more detail in Annex 1 to this Notice.

4.Monitoring tools, profiling and automated decision-making

Some of the technology we use to protect company confidential information and ensure compliance with company policies monitors employee IT usage and employee communications and may automatically filter, record or block the sending of communications, or flag certain communications for further review, subject to meeting local legal requirements. For further information on this, please contact privacy@wtwco.com. Subject to restrictions under local laws, we may also use technology (including third party solutions) to process your Personal Information in a manner that constitutes "profiling". This involves the use of software that is able to evaluate your personal aspects and predict risks or outcomes. We do this to assist in workforce management, for example we may use software to ensure our workforce is managed and utilised efficiently, to predict risks in staff retention, to detect problems in the workplace, and/or to ensure that employees are being compensated fairly. Where biometric login is used by you on company devices such as laptops or mobile devices, your data is stored only on the device and cannot be accessed by Willis Towers Watson Group.

Although we may use this type of technology to assist our decision-making, where required by law, we do not make important decisions about employees (e.g. as to their compensation, dismissal or promotion) without a member of management and/or the HR team assessing all the circumstances.

5.Transfer of Personal Information

Due to the global nature of Willis Towers Watson Group operations, we may disclose Personal Information to personnel and departments in other entities which are part of the Willis Towers Watson Group to fulfil the purposes described in this Notice. This may include transferring Personal Information to other countries (including countries other than where you are based that have a different data protection regime than is found in the country where you are based). Where we use IT applications in

the collection of Personal Information, it may be transferred and hosted in offshore servers or hosting locations as and when it is entered into such IT applications. If you are located in the European Economic Area (the “EEA”), the UK or Switzerland this may include countries outside of the EEA, UK or Switzerland. If you are located in the Cayman Islands, this may include the United States, the European Union, India, and Bermuda. If you are located in Quebec, this may include other Canadian provinces, the

B-3

United States, the European Union, India or other countries. If you are located in the Kingdom of Saudi Arabia, this may include the UK, United States and India. If you are located in Bermuda, this may include Canada, United States, India, the European Union. Some of these countries are recognized by the European Commission or other regulators as providing an adequate level of protection (the full list of these countries deemed adequate in the EU, available here), while others are not. We have established safeguards to protect Personal Information that is transferred to other countries, including appropriate contractual protections such as standard contractual clauses published by applicable regulatory bodies. You may obtain more information about these measures and the Willis Towers Watson Group's Global Privacy Program by contacting privacy@wtwco.com.

Access to Personal Information within the Willis Towers Watson Group will be limited to those who have a need to know the information for the purposes described in Annex 1 to this Notice, and may include your managers and their designees, personnel in the international management, HR, IT, Compliance, Legal, Finance and Accounting and Internal Audit to the extent that it is legally necessary.

All personnel within the Willis Towers Watson Group will generally have access to your business contact information such as name, position, telephone number, postal address, email address and photograph.

From time to time, we and other entities within the Willis Towers Watson Group may need to make Personal Information available to other unaffiliated third parties. For a list of the categories of unaffiliated third parties, please see Annex 1 to this Notice. Some of the unaffiliated third parties will be located outside of your home jurisdiction, including in the United States and other jurisdictions that may not provide an adequate level of protection according to EEA standards. Third party service providers and professional advisors are required to protect the confidentiality and security of Personal Information, and only use Personal Information for the provision of services to Willis Towers Watson Group, and in compliance with applicable law.

When we transfer or disclose your Personal Information, we will do so in accordance with applicable law.

6.Security

Willis Towers Watson Group will use reasonable organizational, technical and administrative measures to protect Personal Information consistent with applicable privacy and data security laws and regulations, including requiring service providers to use appropriate measures to protect the confidentiality and security of Personal Information.

7.Data Processing, Retention and Destruction

The Willis Towers Watson Group uses various processing methods on the Personal Information it collects, including organization and structuring, storage, adaptation / alteration, consultation, use and disclosure.

We will keep your Personal Information for as long as you remain employed by us, and for a period of 10 years thereafter subject to local law requirements. We will only retain your Personal Information after this time if we are required to do so to comply with the law, or if there are outstanding or, where allowed by law, reasonably anticipated claims or complaints that will reasonably require your Personal Information to be retained. For additional details, please review our Records Management Policy.

If there is any information that we are unable, for technical reasons, to delete entirely from our systems, we will put in place appropriate measures to prevent any further processing or use of the data.

When we no longer require the use of your Personal Information, we may anonymize it as described in Annex 1, or we will securely destroy it.

•Collecting and using personal data for a lawful purpose only: We must only collect and use the minimum amount of personal data which is necessary for one or more legitimate business purposes, which must be lawful and justifiable.

•Safeguarding special categories of data: We must only process special categories of data when it is necessary to do so, and we have explicit consent from individuals or another legal basis to legitimise the processing.

•Data protection impact assessments: Where the collection and use of personal data is likely to result in significant risks to the rights and freedoms of individuals, we must carry out an assessment into the impact of the proposed collection and use on individuals.

•Ensuring data quality: We must keep personal data accurate and up to date.

•Retaining and disposing of data: We must keep personal data only for as long as is necessary for a specific business purpose and ensure that it is disposed of securely.

5.2In particular, we must only collect and use special categories of personal information where necessary and where we have a lawful basis to do so.

5.3When relying on explicit consent, we must ensure that suitable and explicit wording expressing the individual’s consent is provided in any consent forms. Where consent is not

B-17

relied upon, we must be able to demonstrate that there is another lawful basis under applicable law for the collection and use of such information and make a record of the basis on which such processing is undertaken.

5.4We may process special categories of personal information without the explicit consent of the individual affected if the processing is for one of the following purposes:

Based on the results of the DPIA, the local Data Protection Officer together with Local Compliance or Legal Teams or the Chief Privacy Officer can advise whether the processing is legitimate and advise how to mitigate any potential risks in this regard. In certain circumstances we may need to consult with the local supervisory authority regarding the use of such data.

GRANT OF PERFORMANCE-BASED RESTRICTED SHARE UNITS

Section 1.24- Grant of the Performance-Based Restricted Share Units

Subject to the terms and conditions of the Plan and the additional terms and conditions set forth in this Agreement and the restrictive covenants set forth in the RCA, the Company hereby grants to the

4

Colleague a number of PSUs equal to the Target Award representing the right to vest in the Earned PSUs. The Colleague agrees that the grant of PSUs pursuant to this Agreement is sufficient consideration for the Colleague entering into the RCA. The Colleague agrees to execute and deliver or electronically accept this Agreement and the RCA within 60 days of the Grant Date. In the event the Colleague fails to execute and deliver or electronically accept the Agreement or the RCA in the manner and within the period specified in this Section 2.1, the Committee may, in its sole discretion, cancel the PSUs.

Section 1.25- PSU Payment

In accordance with Section 7(d)(ii) of the Plan, the Shares to be issued upon vesting and settlement of the PSUs must be fully paid up prior to issuance of such Shares (including, in the interest of clarity, each issuance of Fractional Share Interests) by payment of the Nominal Value per Share. The Committee shall ensure that payment of the Nominal Value for any Shares underlying the PSUs is received by it on behalf of the Colleague at the time the PSUs are settled from a non-Irish Subsidiary or other source and shall establish any procedures or protocols necessary to ensure that payment is timely received.

Section 1.26- Employment or Service Rights

Subject to the terms of the RCA, the rights and obligations of the Colleague under the terms of their Service shall not be affected by their participation in the Plan or any right which they may have to participate in it. The PSUs and the Colleague’s participation in the Plan will not be interpreted to form an employment agreement or service contract with the Company or any Subsidiary or a Designated Associate Company and the terms of any separate employment agreement or service contract to which the Colleague is a party shall remain in effect and will control to the extent that there are any inconsistencies with this Agreement. The Colleague hereby waives any and all rights to compensation or damages in consequence of the termination of Service for any reason whatsoever insofar as those rights arise or may arise from their ceasing to have rights under or be entitled to earn or vest in their PSUs as a result of such termination of Service. If, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, the Colleague shall be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claims.

Section 1.27- Adjustments in PSUs Pursuant to Change of Control or Similar Event, etc.

Subject to Sections 11 and 12 of the Plan, in the event that the outstanding Shares subject to the PSUs are, from time to time, changed into or exchanged for a different number or kind of Shares or other securities, by reason of a share split, spin-off, share or extraordinary cash dividend, share combination or reclassification, recapitalization or merger, Change of Control, or similar event, the Committee shall, in its absolute discretion, substitute or adjust proportionally (i) the number and kind of Shares or securities subject to the PSUs; or (ii) the terms and conditions applicable to the PSUs (including without limitation, any applicable Performance Objectives with respect thereto). An adjustment may have the effect of reducing the price at which Shares may be acquired to less than their Nominal Value (the “Shortfall”), but only if and to the extent that the Committee shall be authorized to capitalize from the reserves of the Company a sum equal to the Shortfall and to apply that sum in paying up that amount on the Shares. Any such adjustment or determination made by the Committee shall be final and binding upon the Colleague, the Company and all other interested persons.

Section 1.28– Tax Withholding

The Colleague acknowledges that, regardless of any action taken by the Employer, the ultimate liability for all Tax-Related Items, is and remains the Colleague’s responsibility and may exceed the amount actually withheld by the Employer. The Colleague further acknowledges that the Company

5

and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PSUs, including, but not limited to, the grant, vesting or settlement of the PSUs, the subsequent sale of Shares acquired pursuant to such settlement and the receipt of any dividends and/or any dividend equivalents; and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the PSUs to reduce or eliminate the Colleague’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Colleague is subject to Tax-Related Items in more than one jurisdiction, the Colleague acknowledges that the Companyand/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, the Colleague agrees to make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items.

In this regard, the Colleague authorizes the Company and/or the Employer, or their respective agents, in their discretion, to satisfy the obligations with regard to all Tax-Related Items by withholding in Shares (including less than a whole Share) to be issued upon settlement of the PSUs, unless the Colleague instead elects, in accordance with the procedures established by the Company, to satisfy the obligations with regard to U.S. Federal Insurance Contribution Act taxes or other Tax-Related Items that become payable in a year prior to the year in which Shares are issued upon settlement of the PSUs and on a date when the Colleague is in the employ of the Employer through withholding from the Colleague’s wages or other cash amounts payable to the Colleague by the Company or the Employer in lieu of withholding in Shares. In the event that such withholding in Shares is problematic under applicable tax or securities law or has materially adverse accounting consequences, by the Colleague’s acceptance of the PSUs, the Colleague authorizes the Company and/or the Employer, or their respective agents, to (i) withhold from the Colleague’s wages or other cash amounts payable to the Colleague from the Company or the Employer, (ii) sell on the Colleague’s behalf a number of Shares (including less than a whole Share) from those Shares issued to the Colleague as the Company determines to be appropriate to generate cash proceeds sufficient to satisfy the obligation for Tax-Related Items, or (iii) utilize any other method of withholding determined by the Company and permitted by applicable laws and the Plan.

The Company may withhold or account for Tax-Related Items by considering statutory withholding rates or other withholding rates, including minimum or maximum applicable rates applicable in the Colleague’s jurisdiction(s). In the event of over-withholding, the Colleague may receive a refund of any over-withheld amount in cash (with no entitlement to the Share equivalent), or if not refunded, the Colleague may seek a refund from the local tax authorities. In the event of under-withholding, the Colleague may be required to pay any additional Tax-Related Items directly to the applicable tax authority or to the Company and/or the Employer. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Colleague is deemed to have been issued the full number of Shares subject to the vested PSUs, notwithstanding that a number of Shares are held back solely for the purpose of paying the Tax-Related Items.

Finally, the Colleague agrees to pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the Colleague’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if the Colleague fails to comply with the Colleague’s obligations in connection with the Tax-Related Items.

Section 1.29- Dividend Equivalents

On each date that a cash dividend is paid to holders of Shares from the Grant Date through the date immediately prior to the date the PSUs are settled, an amount (the “Dividend Equivalent Amount”) equal to the cash dividend that is paid on each Share, multiplied by the Target Award (including PSUs over Fractional Share Interests) and any Dividend Equivalent Units (as defined below) that remain

6

unvested and outstanding as of the dividend payment record date, will be credited to the Colleague, and such credited amount will be converted into an additional number of PSUs (including PSUs over Fractional Share Interests resulting from the foregoing calculation) determined by dividing the Dividend Equivalent Amount by the Fair Market Value of a Share on the date of the dividend payment (“Dividend Equivalent Units”). At the end of the Performance Period, the number of Dividend Equivalent Units will be adjusted to reflect a number of Dividend Equivalent Units that is calculated based on the formula described above, but replacing the Target Award with the number of Earned PSUs (such adjusted number, the “Earned Dividend Equivalent Units”). During the period beginning immediately following the last day of the Performance Period and ending on the date the Earned PSUs are paid pursuant to Section 3.2(a) below, Dividend Equivalent Units will accrue on any Earned PSUs and any Earned Dividend Equivalent Units. Dividend Equivalent Units and Earned Dividend Equivalent Units will be subject to the same conditions as the underlying PSUs with respect to which Dividend Equivalent Units and Earned Dividend Equivalent Units were credited, including without limitation, the vesting condition and the provisions governing time and form of settlement applicable to the underlying PSUs. Unless expressly provided otherwise, as used elsewhere in this Agreement, references to PSUs in this Agreement shall also include Dividend Equivalent Units and Earned Dividend Equivalent Units that have been credited to the Colleague pursuant to this Section 2.6.

Section 1.30- Clawback / Repayment

The PSUs (and any Shares or other payments resulting from settlement thereof or proceeds therefrom) shall be subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to facilitate compliance with (i) any clawback, forfeiture or other similar policy adopted by the Committee or the Board as in effect at the time the PSU award is granted, including, for the avoidance of doubt, the Company’s Compensation Recoupment Policy, effective November 28, 2023, or as may be adopted thereafter as the Committee determines necessary, appropriate or advisable in view of applicable laws, governance considerations or industry best practices; and/or (ii) applicable laws. Further, in the event that the Colleague receives any amount in excess of the amount that the Colleague should otherwise have received under the terms of the PSU award for any reason (including, without limitation, by reason of a financial restatement, mistake in calculations or other administrative error), the Colleague shall be required to repay any such excess amount to the Company.For purposes of the foregoing, the Colleague expressly and explicitly authorizes the Company to issue instructions, on the Colleague’s behalf, to any brokerage firm and/or third-party administrator engaged by the Company to hold any Shares and other amounts acquired pursuant to the PSUs to re-convey, transfer or otherwise return such Shares and/or other amounts to the Company upon the Company’s enforcement of this Section 2.7.

(k)Notwithstanding anything to the contrary in this Section 3.1, no PSUs shall vest prior to the first anniversary of the Grant Date (i) except in the case of the Colleague’s termination of Service resulting from death or Permanent Disability or in connection with a Change of Control, or (ii) unless the Committee, in its sole discretion, determines that the PSUs shall be sourced from the Unrestricted Pool.

Section 1.32- Settlement

(a)Except as otherwise provided in Section 3.2(b), PSUs that become vested shall be settled in Shares (including, in the interest of clarity, Fractional Share Interests underlying the vested PSUs or that result from the withholding of less than a whole Share pursuant to Section 2.5) on the Vesting Date, or, if earlier, upon an accelerated vesting event pursuant to Sections 3.1(g) or (j), or as soon as practicable, but no later than 31 days, thereafter. Notwithstanding the foregoing, a Fractional Share Interest may be paid in cash or rounded to the extent provided in Schedule A for the Colleague’s country or to the extent otherwise determined by the Committee in its sole discretion.

(b)Notwithstanding the foregoing, if the PSUs are considered non-qualified deferred compensation subject to Section 409A of the Code, as determined in the sole discretion of the Company, and the Colleague is a U.S. Taxpayer, PSUs that are no longer subject to a substantial risk of forfeiture, as determined in accordance with Section 409A of the Code, shall be settled, without regard to the vesting schedule set forth above, on the earliest to occur of (i) the Vesting Date, (ii) a “change in control event” within the meaning of U.S. Treas. Reg. § 1.409A-3(i)(5) (a “409A CIC Event”), and (iii) a “separation from service” within the meaning of Section 409A of the Code (a “Separation from Service”) that occurs following a 409A CIC Event, provided that if the Colleague is a “specified employee” within the meaning of Section 409A of the Code on the date the Colleague experiences a Separation from Service, then the PSUs shall instead be settled on the first business day of the seventh month following the Colleague’s Separation from Service, to the extent such delayed payment is required in order to avoid a prohibited distribution under Section 409A of the Code.

Section 1.33- Conditions to Issuance of Shares

The Shares underlying the Earned PSUs to be issued hereunder shall be previously authorized but unissued Shares. Such Shares shall be fully paid.

(b)The Colleague has paid or made arrangements to pay the Tax-Related Items pursuant to Section 2.5.

Without limiting the generality of the foregoing, the Committee may require an opinion of counsel reasonably acceptable to it to the effect that any subsequent transfer of Shares acquired on the settlement of PSUs does not violate the Exchange Act and may issue stop-transfer orders covering such Shares.

9

Section 1.34- Rights as Shareholder

The Colleague shall not be, nor have any of the rights or privileges of, a shareholder of the Company in respect of any Shares that may be received upon the settlement of the PSUs unless and until certificates representing such Shares or their electronic equivalent shall have been issued by the Company to the Colleague.

In the event a Fractional Share Interest is issued, the Colleague shall have with respect to such Fractional Share Interest the right to receive dividends payable with respect to a Share that are proportionate to the interest the Fractional Share Interest bears to a whole Share, but the Colleague shall otherwise not be, nor have any of the other rights or privileges of, a shareholder of the Company, including the right to vote, in respect of any Fractional Share Interests held by the Colleague until the Fractional Share Interests issued to a Colleague aggregate to a whole Share.

Section 1.35- Limitation on Obligations

The Company’s obligation with respect to the PSUs granted hereunder is limited solely to the issuance to the Colleague of Shares within the period when such Shares are due to be issued hereunder, and in no event shall the Company become obligated to pay cash in respect of such obligation.

For any Colleague whose termination of Service with the Company constitutes a Qualifying Retirement (“Qualifying Retiree”), in order for the Qualifying Retiree to continue to vest in the PSUs in accordance with the provisions of Section 3.1(f), the Qualifying Retiree shall furnish to the Company on an annual basis (for the duration of an Award’s vesting), or at such time and in such manner as the Company may otherwise reasonably require from time to time, in a form provided to the Qualifying Retiree: (i) a statement of any outside employment or consulting services in which the Qualified Retiree has engaged or seeks to engage during the period between the Termination Date and the Vesting Date; and (ii) a statement confirming that the Qualifying Retiree has not disclosed or used any Confidential Information as prohibited by the RCA (together with the statement described in Section 6.2(i), the “Retirement Disclosure”). In the event that a Qualifying Retiree does not make the required Retirement Disclosure, or the Company’s Chief Executive Officer, Chief Human Resources Officer, and General Counsel (jointly), or the Committee Chair, in the case of the current or any former Chief Executive Officer of the Company (the “Retirement Compliance Officers”) determine in their sole and absolute discretion that, based on the Retirement Disclosure or otherwise, the Qualifying Retiree is engaging in outside employment or consulting services that are deemed to be competitive with the Business of the Company, as defined by the RCA, in accordance with applicable law in those states or jurisdictions where such provisions are lawful, or that the Qualifying Retiree has breached the obligations regarding the use and disclosure of Confidential Information (each of the foregoing, a “Retirement Noncompliance Event”), the Retirement Compliance Officers may determine, in their sole and absolute discretion in accordance with applicable law in those states or jurisdictions where such a provision is lawful, that all vesting under Section 3.1(f) shall cease immediately and any rights afforded under this Agreement to the Qualified Retiree shall be forfeited. Notwithstanding a finding of a Retirement Noncompliance Event, the Retirement Compliance Officers may, in their sole and absolute discretion, permit the Qualifying Retiree to continue to vest in the PSUs in accordance with the provisions of Section 3.1(f). Notwithstanding the above, pursuant to California Business & Professions Code § 16600.1, if the Colleague is a current employee of the Company who works in California, or if they were employed by the Company in California at any time after January 1, 2022, they are hereby provided with notice that any clause or agreement between them and the Company that prohibits post-employment competition in California is hereby rescinded and shall be deemed null and void.

Section 2.16- Insider Trading / Market Abuse Laws

The Colleague acknowledges that, depending on the Colleague or the Colleague’s broker’s country of residence or where the Shares are listed, the Colleague may be subject to insider trading restrictions and/or market abuse laws, which may affect the Colleague’s ability to accept, acquire, sell or otherwise dispose of Shares or rights to Shares (e.g., PSUs) or rights linked to the value of Shares under the Plan during such times as the Colleague is considered to have “inside information” regarding the Company (as defined by the laws or regulations in the applicable jurisdictions of the Colleague’s country). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Colleague placed before the Colleague possessed inside information. Furthermore, the Colleague could be prohibited from (i) disclosing the inside information to any third party (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them otherwise to buy or sell securities. Third parties include fellow employees and consultants. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Colleague acknowledges they are responsible for complying with any applicable restrictions and is encouraged to speak to their personal legal advisor for further details regarding any applicable insider-trading and/or market-abuse laws in the Colleague’s country.

Section 2.17- Foreign Asset/Account Reporting Requirements and Exchange Controls

The Colleague’s country may have certain foreign asset and/or foreign account reporting requirements and exchange controls which may affect the Colleague’s ability to acquire or hold Shares under the Plan or cash received from participating in the Plan (including from any dividends paid on Shares, sale proceeds resulting from the sale of Shares acquired under the Plan) in a brokerage or bank account outside the Colleague’s country. The Colleague may be required to report such accounts, assets or transactions to the tax or other authorities in the Colleague’s country. The Colleague also may be required to repatriate sale proceeds or other funds received as a result of the Colleague’s participation in the Plan to the Colleague’s country through a designated bank or broker within a certain time after

15

receipt. The Colleague acknowledges that it is their responsibility to be compliant with such regulations, and the Colleague should consult their personal legal advisor for any details.

Section 2.18- Waiver

The Colleague acknowledges that a waiver by the Company of breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by the Colleague or any other participant of the Plan.

Section 2.19- Counterparts

This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original and all of which together shall constitute one and the same instrument.

Section 2.20 - Code Section 409A

For purposes of United States taxpayers, it is intended that the terms of the PSUs will comply with the provisions of Section 409A of the Code and the Treasury Regulations relating thereto so as not to subject the Colleague to the payment of additional taxes and interest under Section 409A of the Code, and this Agreement will be interpreted, operated and administered in a manner that is consistent with this intent. In furtherance of this intent, the Committee may adopt such amendments to this Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, in each case, without the consent of the Colleague, that the Committee determines are reasonable, necessary or appropriate to comply with the requirements of Section 409A of the Code and related United States Department of Treasury guidance. In that light, the Company, its Subsidiaries and any Designated Associate Companies make no representation or covenant to ensure that the PSUs that are intended to be exempt from, or compliant with, Section 409A of the Code are not so exempt or compliant or for any action taken by the Committee with respect thereto. Nothing in the Agreement shall provide a basis for any person to take action against the Company, its Subsidiaries or its Designated Associate Companies based on matters covered by Section 409A of the Code, including the tax treatment of any Shares or other payments made under the PSUs granted hereunder, and the Company, its Subsidiaries and any Designated Associate Companies shall not under any circumstances have any liability to the Colleague or their estate or any other party for any taxes, penalties or interest due on amounts paid or payable under this Agreement, including taxes, penalties or interest imposed under Section 409A of the Code.

16

By the Colleague’s execution or electronic acceptance of this Agreement (including the Schedules attached hereto) in the manner specified in the Colleague’s online account with the Company’s designated broker/stock plan administrator, the Colleague and the Company have agreed that the PSUs are granted under and governed by the terms and conditions of the Plan and this Agreement (including the Schedules attached hereto).

(Performance-Based Restricted Share Units)

WILLIS TOWERS WATSON PUBLIC LIMITED COMPANY

2012 EQUITY INCENTIVE PLAN, AS AMENDED AND RESTATED

Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Agreement or the Plan.

Terms and Conditions

This Schedule A includes additional terms and conditions that govern the PSUs granted to the Colleague under the Willis Towers Watson Public Limited Company 2012 Equity Incentive Plan, as amended from time to time (the “Plan”) and the applicable Performance-Based Restricted Share Unit Agreement (the “Agreement”) if the Colleague resides in one of the countries listed below. This Schedule A forms part of the Agreement. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Agreement or the Plan.

Notwithstanding Section 1.16 and 3.1(f) of the Agreement, if the Company receives a legal opinion that there has been a legal judgment and/or legal development in the Colleague’s jurisdiction that likely would result in the favorable treatment that applies to the PSUs as a result of the Colleague’s retirement or reaching a certain age being unlawful and/or discriminatory, the favorable treatment contemplated under Section 1.16 and 3.1(f) shall not apply and Section 3.1 shall apply to the Colleague without giving effect to Section 3.1(f).

Notifications

This Schedule A also includes information based on the securities, exchange control and other laws in effect in the Colleague’s country as of February 2025. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Colleague not rely on the information noted herein as the only source of information relating to the consequences of the Colleague’s participation in the Plan because the information may be out of date at the time the PSUs vest under the Plan.

In addition, the information is general in nature. The Company is not providing the Colleague with any tax advice with respect to the PSUs. The information provided below may not apply to the Colleague’s particular situation, and the Company is not in a position to assure the Colleague of any particular result. Accordingly, the Colleague should seek appropriate professional advice as to how the tax or other laws in the Colleague’s country apply to the Colleague’s situation.

Finally, if the Colleague is a citizen or resident of a country other than the one in which the Colleague is currently residing and/or working, transfers employment and/or residency after the Grant Date, or is considered a resident of another country for local law purposes, the terms and conditions contained herein for the country the Colleague is residing and/or working in at the time of grant may not be applicable to the Colleague, and the Company shall, in its discretion, determine to what extent the terms and conditions contained herein shall be applicable to the Colleague. Similarly, the information contained herein may no longer be applicable in the same manner.

Willis Towers Watson

Global Employee Personal Information Protection Notice

Last Updated: December 2024

1.Introduction

Willis Towers Watson operates as a global business through its affiliated entities (together “the Willis Towers Watson Group”). The Willis Towers Watson Group values the trust of its employees worldwide and is committed to protecting their personal information.

The Willis Towers Watson Group operates in many different countries. Some of these countries have laws related to the collection, use, transfer and disclosure of the personal information of individuals, including our employees. The purpose of this Global Employee Personal Information Protection Notice (the “Notice”) is to give you information about what personal information the Willis Towers Watson Group collects, uses, transfers and discloses, and why.

The Willis Towers Watson Group entity responsible for collecting and processing your personal data is the entity that employs you. The Willis Towers Watson Group may also engage with outside entities to collect information consistent with this Notice. You can check which entity employs you by checking your contract of employment or by asking your usual HR contact. In this Notice, the term "we" or "us" refers to that entity. The information that we collect about you as an employee allows us to administer your benefits and helps to support routine Human Resources and operational processes, contingency planning, and internal talent searches.

2.What Personal Information about you that we collect, and how we collect Your Personal Information

In the course of your employment, we may have collected or will collect information about you and your working relationship with us, your spouse, domestic/civil partner and/or dependents (“Dependents”). We refer to such information as “Personal Information” (also known as Personal Data in the Cayman Islands). For more specific information regarding what Personal Information about you, we may collect, use, transfer and disclose, and the purposes for which it may be collected, used, transferred and disclosed, please see Annex 1 to this Notice. Local employee handbooks, office manuals, works council agreements and notices provided in your local office or on the Willis Towers Watson intranet site may provide additional details or information.

We may also collect additional Personal Information in operating our business and interacting with individuals in the course of our business, including employment. This may at times include “sensitive" information (otherwise known as “special categories of personal information” under the General Data Protection Regulation (“GDPR”), “sensitive data” under the Saudi Arabian Personal Data Protection Law (“PDPL”), “sensitive personal data” under the Cayman Islands Data Protection Law (“DPL”), or “sensitive personal information” under the California Consumer Privacy Act (“CCPA”) and Bermuda’s Personal Information Protection Act 2016 (“PIPA”)), such as data about your ethnic origin; religious beliefs; health records or criminal conviction data; physical or mental health or condition; medical data; commission, or alleged commission of an offense; any proceedings for an offense committed, or alleged to have been committed. Where required by law, we will provide specific data processing information to you regarding how we may process that data and what rights you may have regarding such processing.

C-1

For the United Kingdom only:

Please see Annex 4 to this Notice for our Policy on the processing of Special Categories of Personal Information.

•Sources of Personal Information

We normally collect your Personal Information directly from you, for example when you apply for a job with us, when you commence your role, and from time to time throughout your employment when we ask you to provide information. We may be required as a consequence of our relationship with you as your employer, or by law, to collect certain Personal Information about you. Failure to provide this information may prevent or delay the fulfilment of our obligations as an employer. We will inform you at the time your information is collected whether certain information is compulsory and the consequences of the failure to provide such information.

We also collect certain Personal Information about you from other sources, including:

(a)background check information from employment screening agencies or publicly available registers (as allowed by law), or references obtained during recruitment;

(b)publicly available professional profiles on websites or social media (e.g. LinkedIn); and

(c)information about your performance or conduct from other employees, clients, or service providers you work with who may provide feedback about you or participate in performance evaluations or reviews.

3.The Legal Bases and purposes for which we use, transfer, and disclose Your Personal Information

UK and EU data protection laws and other laws around the world, for example the PDPL and the DPA and PIPA require that we only process Personal Information subject to one or more valid legal bases. In such cases our legal basis will be one of the following:

(a)to fulfil our contractual obligations to you in connection with your employment contract with us;

(b)to comply with our legal obligations, for example obtaining proof of your identity to enable us to meet our anti-money laundering obligations, or obtaining proof of your right to work status to enable us to meet relevant obligations;

(c)to comply with our legal obligations to you, for example health and safety obligations that we must comply with as your employer or to a third party (e.g. the taxation authorities);

(d)to meet our legitimate interests, for example to manage our employees effectively, to protect us against theft or other crime, to allow you access to our technology and HR resources, and to conduct analytics that allows us to manage our workforce efficiently and plan recruitment activities. When we process Personal Information to meet our legitimate interests, we put in place robust safeguards to ensure that your privacy is protected and to ensure that our legitimate interests are not overridden by your interests or fundamental rights and freedoms;

(e)where a reasonable person would view that you would not reasonably be expected to request that we cease or not begin to use your personal information and that our use will not prejudice your individual rights;

C-2

(f)to protect your or another person's vital interests, for example by providing your health information to a doctor in a medical emergency;

(g)the processing is necessary for medical purposes and is undertaken by (a) a health professional; or (2) a person who, in the circumstances, owes a duty of confidentiality equivalent to that which would arise if that person were a health professional. (see DPA);

(h)the Personal Information is publicly available information and will be used for a purpose that is consistent with the purpose of its public availability (See PIPA);

(i)the use of the Personal Information is necessary in the context of an individual’s present, or past employment relationship with WTW; or

(j)we may obtain your explicit consent to collect and use certain types of Personal Information when we are required to do so by law (for example, when we process some categories of sensitive personal information or, where required by law, execute a processing which is classified as “profiling”). If we ask for your consent to process your personal information, you may withdraw your consent at any time by contacting privacy@wtwco.com.

The purposes for which we use your Personal Information are explained in more detail in Annex 1 to this Notice.

4.Monitoring tools, profiling and automated decision-making

Some of the technology we use to protect company confidential information and ensure compliance with company policies monitors employee IT usage and employee communications and may automatically filter, record or block the sending of communications, or flag certain communications for further review, subject to meeting local legal requirements. For further information on this, please contact privacy@wtwco.com. Subject to restrictions under local laws, we may also use technology (including third party solutions) to process your Personal Information in a manner that constitutes "profiling". This involves the use of software that is able to evaluate your personal aspects and predict risks or outcomes. We do this to assist in workforce management, for example we may use software to ensure our workforce is managed and utilised efficiently, to predict risks in staff retention, to detect problems in the workplace, and/or to ensure that employees are being compensated fairly. Where biometric login is used by you on company devices such as laptops or mobile devices, your data is stored only on the device and cannot be accessed by Willis Towers Watson Group.

Although we may use this type of technology to assist our decision-making, where required by law, we do not make important decisions about employees (e.g. as to their compensation, dismissal or promotion) without a member of management and/or the HR team assessing all the circumstances.

5.Transfer of Personal Information

Due to the global nature of Willis Towers Watson Group operations, we may disclose Personal Information to personnel and departments in other entities which are part of the Willis Towers Watson Group to fulfil the purposes described in this Notice. This may include transferring Personal Information to other countries (including countries other than where you are based that have a different data protection regime than is found in the country where you are based). Where we use IT applications in

C-3

the collection of Personal Information, it may be transferred and hosted in offshore servers or hosting locations as and when it is entered into such IT applications. If you are located in the European Economic Area (the “EEA”), the UK or Switzerland this may include countries outside of the EEA, UK or Switzerland. If you are located in the Cayman Islands, this may include the United States, the European Union, India, and Bermuda. If you are located in Quebec, this may include other Canadian provinces, the United States, the European Union, India or other countries. If you are located in the Kingdom of Saudi Arabia, this may include the UK, United States and India. If you are located in Bermuda, this may include Canada, United States, India, the European Union. Some of these countries are recognized by the European Commission or other regulators as providing an adequate level of protection (the full list of these countries deemed adequate in the EU, available here), while others are not. We have established safeguards to protect Personal Information that is transferred to other countries, including appropriate contractual protections such as standard contractual clauses published by applicable regulatory bodies. You may obtain more information about these measures and the Willis Towers Watson Group's Global Privacy Program by contacting privacy@wtwco.com.

Access to Personal Information within the Willis Towers Watson Group will be limited to those who have a need to know the information for the purposes described in Annex 1 to this Notice, and may include your managers and their designees, personnel in the international management, HR, IT, Compliance, Legal, Finance and Accounting and Internal Audit to the extent that it is legally necessary.

All personnel within the Willis Towers Watson Group will generally have access to your business contact information such as name, position, telephone number, postal address, email address and photograph.

From time to time, we and other entities within the Willis Towers Watson Group may need to make Personal Information available to other unaffiliated third parties. For a list of the categories of unaffiliated third parties, please see Annex 1 to this Notice. Some of the unaffiliated third parties will be located outside of your home jurisdiction, including in the United States and other jurisdictions that may not provide an adequate level of protection according to EEA standards. Third party service providers and professional advisors are required to protect the confidentiality and security of Personal Information, and only use Personal Information for the provision of services to Willis Towers Watson Group, and in compliance with applicable law.

When we transfer or disclose your Personal Information, we will do so in accordance with applicable law.

6.Security

Willis Towers Watson Group will use reasonable organizational, technical and administrative measures to protect Personal Information consistent with applicable privacy and data security laws and regulations, including requiring service providers to use appropriate measures to protect the confidentiality and security of Personal Information.

7.Data Processing, Retention and Destruction

The Willis Towers Watson Group uses various processing methods on the Personal Information it collects, including organization and structuring, storage, adaptation / alteration, consultation, use and disclosure.

We will keep your Personal Information for as long as you remain employed by us, and for a period of 10 years thereafter subject to local law requirements. We will only retain your Personal Information after this time if we are required to do so to comply with the law, or if there are outstanding or, where allowed by law, reasonably anticipated claims or complaints that will reasonably require your Personal Information to be retained. For additional details, please review our Records Management Policy.

C-4

If there is any information that we are unable, for technical reasons, to delete entirely from our systems, we will put in place appropriate measures to prevent any further processing or use of the data.

When we no longer require the use of your Personal Information, we may anonymize it as described in Annex 1, or we will securely destroy it.

8.Access and correction requests, questions, and complaints

You have certain rights regarding your Personal Information, subject to local law, which may include the right to request:

•correct the information we hold about you;

5.The Rules on processing special categories of personal information

5.1The Willis Towers Watson Global Privacy Policy must be followed when processing special categories of personal information. This contains the following rules and sets out the practical steps that apply in relation to each rule:

The Rules

•Transparency: We must be transparent about the way in which we use personal data.

•Collecting and using personal data for a lawful purpose only: We must only collect and use the minimum amount of personal data which is necessary for one or more legitimate business purposes, which must be lawful and justifiable.

•Safeguarding special categories of data: We must only process special categories of data when it is necessary to do so, and we have explicit consent from individuals or another legal basis to legitimise the processing.

•Data protection impact assessments: Where the collection and use of personal data is likely to result in significant risks to the rights and freedoms of individuals, we must carry out an assessment into the impact of the proposed collection and use on individuals.

•Ensuring data quality: We must keep personal data accurate and up to date.

•Retaining and disposing of data: We must keep personal data only for as long as is necessary for a specific business purpose and ensure that it is disposed of securely.

•Respecting individuals' rights: We must be receptive to any queries, requests or complaints made by individuals in connection with their personal data in accordance with applicable law.

•Taking appropriate security measures: We must implement appropriate technical and organisational security measures to protect personal data.

•Adopting privacy by design: We must adopt privacy by design and privacy by default in systems, databases, tools and features that process personal data.

•Using subcontractors/vendors: We must ensure that providers of services to us also adopt appropriate and equivalent security measures.

•Disclosing to third parties: We must only comply with requests for disclosure of personal data to third parties where we have a legal basis on which to do so, or with the consent of affected individuals.

•Ensuring adequate protection for international transfers: We must ensure that adequate protection is put in place when making transfers of personal data from one country to another country.

C-21

5.2In particular, we must only collect and use special categories of personal information where necessary and where we have a lawful basis to do so. The lawful basis for processing is usually explicit consent, but the Act permits some processing of special category personal data without consent in the circumstances set out in the table below. In addition, we may be able to process special category personal data personal data without explicit consent when we are co-operating in criminal or other government investigations or inquiries. Prior to processing special category personal data for criminal or other government investigations or inquiries you must consult the local Compliance Team and local Legal counsel who in turn may consult with the Chief Privacy Officer if necessary. All exceptions must be authorised by the Global Head of Compliance.

5.3When relying on explicit consent, we must ensure that suitable and explicit wording expressing the individual’s consent is provided in any consent forms. Where consent is not relied upon, we must be able to demonstrate that there is another lawful basis under applicable law for the collection and use of such information and make a record of the basis on which such processing is undertaken.

C-22

5.4We may process special categories of personal information without the explicit consent of the individual affected if the processing is for one of the following purposes:

Act Ref in Schedule 1	Purpose	Examples
Paragraph 1	Employment, social security and social protection	Processing health information for managing employee sick leave and pay
Paragraph 2	Health or social care purposes	Processing disability information for assessing the working capability of employees

Paragraph 20	Insurance	Processing health information or crime- related information for an insurance purpose

5.5The local Data Protection Officer and the Chief Privacy Officer should be informed of any planned significant use of special categories of data. Where the processing of special category data is likely to pose significant risks to the rights and freedoms of individuals, a Data Protection Impact Assessment (DPIA) must be carried out.

Nature of Operations

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.

Basis of Presentation and Recent Accounting Pronouncements

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 six months ended June 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

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

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. Although the litigation remains pending, in March 2025, the SEC voted to end its defense of 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.

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 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 over the next twelve months and does not expect H.R. 1 to have a material impact on its financial results of operations.

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 June 30, 2025 and December 31, 2024:

	June 30, 2025		December 31, 2024
Billed receivables, net of allowance for doubtful accounts of $34 million and $36 million	$	1,694	$	1,604
Unbilled receivables		527		569
Current contract assets		143		321
Accounts receivable, net	$	2,364	$	2,494
Non-current accounts receivable, net	$	27	$	18
Deferred revenue	$	765	$	732

During the three and six months ended June 30, 2025, revenue of $116 million and $462 million, respectively, was recognized that was reflected as deferred revenue at December 31, 2024. During the three months ended June 30, 2025, revenue of $302 million was recognized that was reflected as deferred revenue at March 31, 2025.

During the three and six months ended June 30, 2025, the Company recognized revenue of less than $1 million related to performance obligations satisfied prior to 2025.

Performance Obligations

The Company has contracts for which performance obligations have not been satisfied as of June 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 June 30, 2025	$	331	$	583	$	717	$	1,631

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 June 30, 2025 have been excluded from the table above.

Segment Reporting [Abstract]

Segment Information

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.

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 June 30, 2025 and 2024.

Restructuring and Related Activities [Abstract]

Restructuring Costs

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 $3 million and $21 million for the three and six months ended June 30, 2024, respectively. Other costs incurred under the Transformation program are included in transaction and transformation and were $86 million and $205 million during the three and six months ended June 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:

Income Tax Disclosure [Abstract]

Income Taxes

Note 7 — Income Taxes

Benefit from income taxes for the three months ended June 30, 2025 was $21 million compared to a provision for income taxes of $26 million for the three months ended June 30, 2024. Provision for income taxes was $44 million and $74 million for the six months ended June 30, 2025 and 2024, respectively. The effective tax rates were (6.8)% and 7.1% for the three and six months ended June 30, 2025, respectively, and 15.6% and 18.1% for the three and six months ended June 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 current-year quarter’s effective tax rate is lower primarily due to favorable discrete tax items, which include an adjustment to the tax provision associated with the earnout received from the sale of our Willis Re business, changes in measurement for existing uncertain tax positions and an excess tax benefit on share-based compensation.

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 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 $2 million, excluding interest and penalties.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

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 June 30, 2025 and December 31, 2024 had total notional amounts of $151 million and $176 million, respectively, with a net fair value asset of $7 million and a net fair value liability of $2 million, respectively.

At June 30, 2025, the Company estimates, based on current exchange rates, there will be $4 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 June 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 six months ended June 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 six months ended June 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 June 30, 2025 and December 31, 2024, we had notional amounts $879 million and $1.2 billion, respectively, with a net fair value asset of $2 million and a net fair value liability of $3 million, respectively. 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 six months ended June 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):

Fair Value Measurements and Investments

Fair Value Disclosures [Abstract]

Fair Value Measurements and Investments

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 following tables present our assets and liabilities measured at fair value on a recurring basis at June 30, 2025 and December 31, 2024:

(iii)Consists of the Towers Watson Alternative Credit Fund, for which the redemption period is generally quarterly, however requires a 50-day notice.

(iv)See Note 9 — Derivative Financial Instruments for further information on our derivative investments.

(v)Probability weightings are based on our knowledge of the past and planned performance of the acquired entity to which the contingent consideration applies. The fair value weighted-average discount rates used in our material contingent consideration calculations were 11.00% and 13.43% at June 30, 2025 and December 31, 2024, respectively. Using different probability weightings and discount rates could result in an increase or decrease of the contingent consideration payable.

(vi)Consideration due to be paid across multiple years until 2029.

The following table summarizes the change in fair value of the Level 3 liabilities:

There were no significant transfers to or from Level 3 in the six months ended June 30, 2025

Held-to-Maturity Securities

During the three months ended June 30, 2025, the Company invested $50 million in debt securities, which it intends to hold to maturity. The following table summarizes the types of holdings and related values:

Non-recurring Fair Value Measurement

The Company has assets that may be required to be recorded at fair value on a non-recurring basis. These assets are evaluated when certain triggering events occur (including the planned disposal of a business or a decrease in estimated future cash flows) that indicate their carrying amounts may not be recoverable.

Fair Value Information about Financial Instruments Not Measured at Fair Value

The following tables present our assets and liabilities not measured at fair value on a recurring basis at June 30, 2025 and December 31, 2024:

(i)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 because 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 not make any contributions to its U.S. plans during the six months ended June 30, 2025 and currently does not anticipate making contributions over the remainder of the fiscal year. The Company made contributions of $1 million to its U.K. plans for the six months ended June 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 six months ended June 30, 2025 and anticipates making additional contributions of $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 $41 million and $81 million during the three and six months ended June 30, 2025, respectively, and $42 million and $85 million during the three and six months ended June 30, 2024, respectively.

Commitments and Contingencies

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 June 30, 2025, we have not incurred a material loss with respect to the indemnification of such third parties. In addition, as of June 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 June 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.

Earnings Per Share [Abstract]

Earnings Per Share

Note 18 — Earnings Per Share

Basic and diluted earnings per share are calculated by dividing net income attributable to WTW by the average number of ordinary shares outstanding during each period. The computation of diluted earnings 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 June 30, 2025 and 2024, there were 0.3 million and 0.5 million restricted time-based stock units outstanding, respectively, and 0.7 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 June 30, 2025 and 2024.

Basic and diluted earnings per share are as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2025			2024			2025			2024
Net income attributable to WTW	$	331		$	141		$	566		$	331
Basic average number of shares outstanding		99			103			100			103
Dilutive effect of potentially issuable shares		1			—			—			1
Diluted average number of shares outstanding		100			103			100			104
Basic earnings per share	$	3.34		$	1.37		$	5.68		$	3.22
Dilutive effect of potentially issuable shares		(0.02	)		(0.01	)		(0.04	)		(0.02	)
Diluted earnings per share	$	3.32		$	1.36		$	5.64		$	3.20

For the three and six months ended June 30, 2025 and 2024, 0.3 million and 0.1 million restricted stock units, respectively, 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 six months ended June 30, 2025 and 2024.

Accounting Policies [Abstract]

Basis of Presentation

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 six months ended June 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

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

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. Although the litigation remains pending, in March 2025, the SEC voted to end its defense of 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.

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

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 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 over the next twelve months and does not expect H.R. 1 to have a material impact on its financial results of operations.

Fair Value of Financial Instruments

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.

Segment Reporting, CODM, Individual Title and Position or Group Name [Extensible Enumeration]	srt:ChiefExecutiveOfficerMember
Segment Reporting, CODM, Profit (Loss) Measure, How Used, Description	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.
