Disclaimer Regarding For****ward-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 or certain considerations relating to our future results. All statements, other than statements of historical facts, that address activities, events or developments that we expect or anticipate may occur in the future, including such things as: our outlook; the potential impact of natural or man-made disasters like health pandemics and other world health crises; future capital expenditures; ongoing working capital efforts; future share repurchases; financial results (including our revenue, costs or margins) and the impact of changes to tax laws on our financial results; existing and evolving business strategies; our ability to execute strategic transactions, including both acquisitions and dispositions, including our ability to receive adequate consideration or any earnout proceeds in return for any dispositions or integrate or manage acquired businesses or effect internal reorganizations; incremental risks relating to the transitional arrangements in effect subsequent to our previously-completed sale of TRANZACT; demand for our services and competitive strengths; strategic goals; the benefits of new initiatives; growth of our business and operations; the sustained health of our product, service, transaction, client, and talent assessment and management pipelines; our ability to successfully manage ongoing leadership, organizational and technology changes, including investments in improving systems and processes; our recognition of future impairment charges; and plans and references to future successes, including our future financial and operating results, short-term and long-term financial goals, plans, objectives, expectations and intentions, including with respect to free cash flow generation, adjusted net income, adjusted operating margin and adjusted earnings per share, are forward-looking statements. Also, when we use words such as ‘may’, ‘will’, ‘would’, ‘anticipate’, ‘believe’, ‘estimate’, ‘expect’, ‘intend’, ‘plan’, ‘continues’, ‘seek’, ‘target’, ‘goal’, ‘focus’, ‘probably’, or similar expressions, we are making forward-looking statements. Such statements are based upon the current beliefs and expectations of the Company’s management and are subject to significant risks and uncertainties. Actual results may differ from those set forth in the forward-looking statements. All forward-looking disclosure is speculative by its nature.

A number of risks and uncertainties that could cause actual results to differ materially from the results reflected in these forward-looking statements are identified under ‘Risk Factors’ in Item 1A of this Annual Report on Form 10-K. These statements are based on assumptions that may not come true and are subject to significant risks and uncertainties.

Although we believe that the assumptions underlying our forward-looking statements are reasonable, any of these assumptions, and therefore also the forward-looking statements based on these assumptions, could themselves prove to be inaccurate. Given the significant uncertainties inherent in the forward-looking statements included in this Annual Report on Form 10-K, 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.

PART I.

The Company

WTW is a leading global advisory, broking and solutions company that provides data-driven, insight-led solutions in the areas of people, risk and capital. Utilizing the global view and local expertise of our approximately 49,000 colleagues serving more than 140 countries and markets, we help organizations sharpen strategies, enhance resilience, motivate workforces and maximize performance. 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. Working closely with our clients, we uncover opportunities for sustainable success.

Our clients operate on a global and local scale in a multitude of businesses and industries throughout the world and generally range in size from large, major multinational corporations to middle-market domestic and international companies. Our clients include many of the world’s leading corporations, including approximately 96% of the FTSE 100, 89% of the Fortune 1000, and 90% of the Fortune Global 500 companies. We also advise the majority of the world’s leading insurance companies. We work with major corporations, emerging growth companies, governmental agencies and not-for-profit institutions in a wide variety of industries, with many of our client relationships spanning decades. None of the Company’s clients individually represented more than 10% of its consolidated revenue for each of the years ended December 31, 2024, 2023 and 2022. We place insurance with approximately 2,500 insurance carriers, none of which individually accounted for a significant concentration of the total premiums we placed on behalf of our clients in 2024, 2023 or 2022.

Available Information

The Company files annual, quarterly and current reports, proxy statements and other information with the SEC. The SEC maintains a website that contains annual, quarterly and current reports, proxy statements and other information that issuers (including WTW) file electronically with the SEC. The SEC’s website is www.sec.gov.

The Company makes available, free of charge through our website, www.wtwco.com, our Annual Report on Form 10-K, our quarterly reports on Form 10-Q, our proxy statement, current reports on Form 8-K and Forms 3, 4, and 5 filed on behalf of directors and Section 16 officers, as well as any amendments to those reports filed or furnished pursuant to the Securities Exchange Act of 1934 (the ‘Exchange Act’) as soon as reasonably practicable after such material is electronically filed with, or furnished to, the SEC. Unless specifically incorporated by reference, information on our website is not a part of this Form 10-K.

The Company’s Memorandum and Articles of Association, Corporate Governance Guidelines, Audit Committee Charter, Risk and Operational Oversight Committee Charter, Human Capital and Compensation Committee Charter, and Corporate Governance and Nominating Committee Charter are available on our website, www.wtwco.com, in the Investor Relations section, or upon request.

General Information

WTW offers its clients a broad range of services and solutions to help them to identify and control their risks, and to enhance business performance by improving their ability to attract, retain and engage a talented workforce. Our risk control services range from strategic risk consulting (including providing actuarial analysis) to a variety of due diligence services, to the provision of practical on-site risk control services (such as health and safety or property loss control consulting), as well as analytical and advisory services (such as hazard modeling and climate risk quantification). We assist clients in planning how to manage 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 our clients 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.

We derive the majority of our revenue from either commissions or fees for brokerage or consulting services. We do not determine the insurance premiums on which our commissions are generally based. Commission levels generally follow the same trend as premium levels as they are derived from a percentage of the premiums paid by the insureds. Fluctuations in these premiums charged by the insurance carriers can therefore have a direct and potentially material impact on our results of operations. Our fees for consulting services are spread across a variety of complementary businesses that generally remain 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.

Business Strategy

We believe that a unified and integrated approach to advisory, broking and solutions can be a path to growth for organizations around the world. We harness our collective power as ‘One WTW’ to make smart connections to serve and support our clients.

We operate in attractive markets – both growing and mature – with a diversified platform across industries, segments and businesses globally.

Our strategy is focused on extending and amplifying WTW’s strengths to deliver sustainable growth and profitability.

We believe we can achieve this through executing on our three objectives:

Accelerate performance: By executing on the segment growth strategies to strengthen business fundamentals, advance innovative solutions and capitalize on our global footprint.

Enhance efficiency: By having a continuous improvement mindset, delivering operating leverage in our segments and leveraging WTW Enterprise Delivery Organization (WE DO) to focus on right work, right place, right tools and real estate optimization.

Optimize portfolio: By intentionally managing our portfolio through inorganic and organic investment in areas of strength and deepen our large and high-growth businesses with strategic investments in corporate risk and broking, health and benefits and wealth. Also, by divesting businesses that are no longer a strategic fit or do not have our desired financial profile.

These objectives are enabled by a focused investment framework and capital allocation strategy.

Through this strategy, we aim to grow revenue, improve margins and increase free cash flow, EBITDA and earnings. In turn, we’ll be able to fulfill our shared company purpose – We transform tomorrows.

We care as much about how we work as we do about the impact that we make. This means commitment to our shared purpose and values, a framework that guides how we run o

Executive Summary of Risk Factors

The following contains a summary of each of our risk factors. For the complete disclosure of each risk factor contained herein, please click on the respective summary.

Strategic and Operational Risks

Our success largely depends on our ability to achieve our global business strategy as it evolves, and our results of operations and financial condition could suffer if the Company were unable to successfully establish and execute on its strategy and generate anticipated revenue growth and cost savings and efficiencies.

We may not be able to fully realize the anticipated benefits of our strategy or our expected product, service and transaction pipelines.

Our ability to successfully manage ongoing organizational changes could impact our business results and may involve significant or evolving costs and/or disruption to the management and/or operations of our business and generate fewer benefits than originally expected.

The growth and portfolio optimization elements of our strategy depend, in part, on our ability to execute strategic transactions, including both acquisitions and dispositions. We face risks when we acquire or divest businesses, and we could have difficulty in acquiring, integrating or managing acquired businesses, or with effecting internal reorganizations, all of which could harm our business, financial condition, results of operations and/or reputation.

The growth element of our strategy also depends, in part, on organic growth and our ability to develop and grow new and existing areas of our business. We face risks when we invest in new lines of business, products, services and platforms or other areas, which could harm our business, financial condition, results of operations and/or reputation.

Our business performance and growth plans could be negatively affected if we are not able to develop and implement improvements in technology and effectively apply technology, data and analytics to drive value for our clients through technology-based solutions or gain internal efficiencies through the effective application of technology, analytics and related tools.

Business Environment Risks

Macroeconomic trends, including inflation, changes in interest rates and trade policies, as well as political events, trade and other international disputes, war, terrorism, natural disasters, public health issues and other business interruptions, can adversely affect our business, results of operations or financial condition.

Demand for our services could decrease for various reasons, including a general economic downturn, increased competition, or a decline in a client’s or an industry’s financial condition or prospects, all of which could substantially and negatively affect us.

Damage to our business, including to our reputation, arising from, among other things, the failure of third parties on whom we rely to perform services or maintain positive public perceptions, could adversely affect our business, operations and results.

Our business may be harmed by any negative developments that may occur in the insurance industry or if we fail to maintain good relationships with insurance carriers.

Human Capital Risks

We depend on the continued services of our executive officers, senior management team, and skilled individual contributors, and any changes in our management structure and in senior leadership could affect our business and financial results.

The loss of key colleagues or a large number of colleagues could damage or result in the loss of client relationships and could result in such colleagues competing against us.

Failure to maintain our corporate culture, including in a remote or hybrid work environment, could damage our reputation.

Intellectual Property, Technology, Cybersecurity and Data Protection Risks

Data and cybersecurity breaches or improper disclosure of confidential company or personal data could result in material financial loss, regulatory actions, reputational harm and/or legal liability.

Our inability to comply with complex and evolving laws and regulations related to data privacy and cybersecurity could result in material financial loss, regulatory actions, reputational harm and/or legal liability.

Our inability to successfully mitigate and recover should we experience a disaster or other business continuity problem could cause material financial loss, loss of human capital, regulatory actions, reputational harm and/or legal liability.

Material interruption to or loss of our information processing capabilities or failure to effectively maintain and upgrade our information processing hardware or systems could cause material financial loss, regulatory actions, reputational harm and/or legal liability.

Limited protection of our intellectual property could harm our business and our ability to compete effectively, and we face the risk that our services or products may infringe upon the intellectual property rights of others.

Legal, Non-Financial/Regulatory and Compliance Risks

From time to time, we receive claims and are party to lawsuits arising from our work, which could materially adversely affect our reputation, business, financial condition or results of operations.

We are subject from time to time to inquiries or investigations by governmental agencies or regulators that could have a material adverse effect on our business, financial condition or results of operations.

We are subject to political, economic, legal, regulatory, compliance, cultural, market, operational and other risks that are inherent in operating our global businesses.

Sanctions imposed by governments, or changes to such sanction regulations (such as sanctions imposed on Russia and China), and related counter-sanctions, could have a material adverse impact on our operations or financial results.

Our business will be negatively affected if we are not able to anticipate and keep pace with rapid changes in government laws or regulations, or if government laws or regulations decrease the need for our services, increase our costs or limit our compensation.

Our compliance systems and controls cannot guarantee that we comply fully with all applicable federal and state or foreign laws and regulations, and actions by regulatory authorities or changes in applicable laws and regulations in the jurisdictions in which we operate could impact our operations and/or have an adverse effect on our business.

Allegations of conflicts of interest or anti-competitive behavior, including in connection with accepting market derived income (‘MDI’), may have a material adverse effect on our business, financial condition, results of operation or reputation.

Our global operations expose us to increasing, and sometimes conflicting, legal and regulatory requirements in environmental, social and governance (‘ESG’) matters, and violation of these regulations could harm our business.

Increasing scrutiny and changing or competing expectations from government authorities, investors, clients and our colleagues with respect to our sustainability practices can impose additional costs on us or expose us to reputational, litigation or other risks.

The economic, regulatory and political impact of the United Kingdom’s exit from the European Union, which occurred on January 31, 2020, could adversely affect us.

Financial and Related Regulatory Risks

We have material pension liabilities that can fluctuate significantly and adversely affect our financial position or net income or result in other financial impacts.

None.

WTW’s management is responsible for the day-to-day management of risks, and the board, including through its committees, is responsible for understanding and overseeing the various risks facing WTW. As a professional services firm providing advice, broking and solutions in the areas of people, risk and capital, and often involving confidential and sensitive information, cybersecurity risk management is an integral part of our enterprise risk management (‘ERM’) strategy.

Cybersecurity Risk Management and Strategy

Increased global cybersecurity vulnerabilities, threats and more sophisticated and targeted cyber-related attacks pose an ongoing risk to the security of our information systems and networks. WTW seeks to manage cybersecurity risks consistent with its general approach to ERM. As further described below, our cybersecurity risk management program is coordinated by cross-functional teams. Technology and cyber risks that meet certain thresholds are escalated and tracked by the ERM team within the WTW Risk function.

WTW has been certified by ISO 27001 and identifies, categorizes and manages cyber risks according to frameworks such as SOC 2 - Type 2 and the National Institute of Standards and Technology (‘NIST’) Framework. Additionally, WTW undertakes vulnerability scanning, and engages third parties from time-to-time to conduct penetration testing to help WTW identify and reduce the threat of known and emerging cybersecurity risks.

Board Oversight and Governance

WTW’s board of directors has delegated the oversight of cybersecurity risks to the Risk and Operational Oversight Committee (the ‘Risk Committee’), which was recently formed following the completion of the three-year term of the Operational Transformation Committee. The Risk Committee assists the board of directors in its oversight of the ERM framework, policies, and practices used by WTW to identify, assess, and manage WTW’s key operational risks, including without limitation: cybersecurity, technology, information security, privacy, and artificial intelligence risk. WTW’s Chief Information Security Officer (‘CISO’) and Global Head of Technology report to the Risk Committee on cybersecurity matters, including key risks. The Risk Committee reports to the board of directors at each formal board meeting and the board of directors discusses those reports.

Management Oversight and Governance

Management plays an important role in assessing and managing WTW’s material risks from cybersecurity threats. The CISO is responsible for designing and implementing a security program and strategy. WTW's CISO has served in various roles in information technology and information security for over 33 years, including serving as CISO of several public companies. The CISO holds undergraduate and graduate degrees in mathematics and strategic information systems and has attained the professional certification of

Certified Information Systems Security Professional. The CISO reports to the Global Head of Technology. WTW’s Global Head of Technology has served in various roles in information technology for over 25 years. The Global Head of Technology holds a graduate degree in business.

As part of the WTW cybersecurity program, cross-functional teams throughout WTW, including enterprise risk management, operational resilience, legal, compliance and information security, coordinate to monitor, consider, and, when appropriate, address cybersecurity threats and respond to cybersecurity incidents. Through ongoing communications among these teams, the CISO, the Global Head of Technology, and other members of senior management, as appropriate, are informed about and monitor the prevention, detection, mitigation, and remediation of cybersecurity threats and incidents and escalate such threats and incidents as appropriate through the processes described in more detail below.

WTW’s cybersecurity program is an ongoing process designed to identify, assess and manage WTW’s risk exposures over the short-, intermediate- and long-term. Management’s cybersecurity risk management strategy and processes include the following areas of focus:

Incident Response Planning: WTW has a global Information and Cyber Security Incident Response Plan (‘ICSIRP’ or ‘Plan’) for identifying and managing cyber and data security threats. The ICSIRP defines the roles and responsibilities of WTW stakeholders involved in responding to cyber and data security events, severity levels and incident categories, and it outlines a process for incident management, including escalation and communication procedures.

Technical Safeguards: WTW seeks to continuously improve implemented technical safeguards that are designed to protect WTW’s information systems. Standards include controls for access management, cyber threat and incident management, data security, encryption, human resource security, network and device security, secure asset management, secure system development, security operations and third-party security. While WTW seeks to maintain adequate controls, they may not always be effective or at the level of maturity that the Company ultimately wishes to maintain. See Part I, Item 1A Risk Factors under the heading ‘Data and cybersecurity breaches or improper disclosure of confidential company or personal data could result in material financial loss, regulatory actions, reputational harm and/or legal liability’ for more information about WTW’s technical controls, management, mitigation, and security practices as well as the risks related thereto.

Education and Awareness: WTW’s policy requires annual, mandatory privacy and information security training for all WTW colleagues.

Third-Party Risk Management: WTW’s risk management strategy includes a risk management process focused on third-party service providers and other parties with which we engage that is intended to align with the technology security key controls across the organization.

Threat Intelligence: Through its regular monitoring processes, WTW obtains intelligence on cyber threats relevant to the Company at strategic, operational and tactical levels to help inform and reassess its cybersecurity risk management priorities.

Material Effects of Cybersecurity Incidents

Although we and our vendors regularly experience cybersecurity incidents, we do not believe that risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected our business strategy, results of operations or financial condition. However, there is no guarantee that a future cyber incident would not materially affect our business strategy, results of operations or financial condition. To learn more about risks from cybersecurity threats, review the risk factors included in Part I, Item 1A Risk Factors in this Annual Report on Form 10-K, as updated by WTW’s subsequent SEC filings. The risks described in such filings are not the only risks facing WTW. Additional risks and uncertainties not currently known or that may currently be deemed to be immaterial also may materially adversely affect WTW’s business, financial condition or results of operations.

We operate offices in many countries throughout the world and believe that our properties are generally suitable and adequate for the purposes for which they are used. The principal properties are located in the United States and the United Kingdom. In addition, we have other offices in various locations, including among others, Europe, Asia, Australia and Latin America. Operations of each of our segments are carried out in owned or leased offices under operating leases that typically do not exceed 10 years in length, except for certain properties in key locations. We do not anticipate difficulty in meeting our space needs at lease expiration.

From time to time, we are party to various lawsuits, arbitrations or mediations that arise in the ordinary course of business. The disclosure called for by Item 3 regarding our legal proceedings is incorporated by reference herein from Note 15 — Commitments and Contingencies, within Item 8 in this Annual Report on Form 10-K.

Not applicable.

PART II.

Share Data

Our ordinary shares trade on the NASDAQ Global Select Market under the symbol ‘WTW’ as of January 10, 2022. As of February 24, 2025, there were 958 shareholders of record of our ordinary shares, not including those ordinary shares held in street or nominee name.

Dividends

We normally pay dividends on a quarterly basis to shareholders of record on March 31, June 30, September 30 and December 31. In February 2025, the board of directors approved a quarterly cash dividend of $0.92 per share ($3.68 per share annualized rate), which will be paid on or around April 15, 2025 to shareholders of record as of March 31, 2025.

There are no governmental laws, decrees or regulations in Ireland that restrict the remittance of dividends or other payments to non-resident holders of the Company’s shares.

In circumstances where one of Ireland’s many exemptions from dividend withholding tax (‘DWT’) does not apply, dividends paid by the Company will be subject to Irish DWT (currently 20 percent). Residents of the United States should be exempt from Irish DWT provided relevant documentation supporting the exemption has been put in place. While the U.S.-Ireland Double Tax Treaty contains provisions reducing the rate of Irish DWT in prescribed circumstances, it should generally be unnecessary for U.S. residents to rely on the provisions of this treaty due to the wide scope of exemptions from Irish DWT available under Irish domestic law. Irish income tax may also arise in respect of dividends paid by the Company. However, U.S. residents entitled to an exemption from Irish DWT generally have no Irish income tax liability on dividends.

With respect to non-corporate U.S. shareholders, certain dividends from a qualified foreign corporation may be subject to reduced rates of taxation. A foreign corporation is treated as a qualified foreign corporation with respect to dividends received from that corporation on shares that are readily tradeable on an established securities market in the United States, such as our shares. Non-corporate U.S. shareholders that do not meet a minimum holding period requirement for our shares during which they are not protected from the risk of loss or that elect to treat the dividend income as investment income pursuant to section 163(d)(4) of the Code will not be eligible for the reduced rates of taxation regardless of our status as a qualified foreign corporation. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. U.S. shareholders should consult their own tax advisors regarding the application of these rules given their particular circumstances.

The graph charts the performance of $100 invested on the initial date indicated, December 31, 2019, assuming full dividend reinvestment.

Unregistered Sales of Equity Securities and Use of Proceeds

During the year ended December 31, 2024, no shares were issued by the Company without registration under the Securities Act of 1933, as amended.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

The Company is authorized to repurchase shares, by way of redemption, 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. The following table presents specified information about the Company’s repurchases of ordinary shares in the fourth quarter and the Company’s repurchase authority.

The board of directors has authorized the current open-ended repurchase program for a total of up to $10.2 billion, which was most recently increased by $1.0 billion on November 20, 2024. At December 31, 2024, the maximum number of shares that may be purchased under the existing stock repurchase program is 4,602,709, with approximately $1.4 billion 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 December 31, 2024 of $313.24.

Securities Authorized for Issuance Under Equity Compensation Plans

The following table provides information, as of December 31, 2024, about the securities authorized for issuance under the Company’s equity compensation plans and is categorized according to whether or not the equity plan was previously approved by shareholders.

(i)

Includes options and RSUs outstanding under the Towers Watson & Co. 2009 Long-Term Incentive Plan and the 2012 Equity Incentive Plan (‘2012 Plan’). The Company intends to only grant future awards under the 2012 Plan.

(ii)

Represents shares available for issuance pursuant to awards that may be granted under the 2012 Plan (3,911,221 shares) and the Willis Towers Watson Public Limited Company Amended and Restated 2010 North American Employee Stock Purchase Plan (1,008,481 shares).

This discussion includes forward-looking statements. See ‘Disclaimer Regarding Forward-looking Statements’ for certain cautionary information regarding forward-looking statements and Part I, Item 1A Risk Factors for 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.

Our methods of calculating these measures may differ from those used by other companies and therefore comparability may be limited. These financial measures should be viewed in addition to, not in lieu of, the consolidated financial statements for the year ended December 31, 2024.

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 stabilizing to 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 volatility and disruption as a result of the ongoing Russia-Ukraine and Middle East conflicts. Although the length and impact of these situations are highly unpredictable, the conflicts have contributed to negative impacts on and volatility of the global economy and capital markets, resulting in significant inflation and fluctuating interest rates in

many of the markets in which we operate, and could continue to lead to further market disruptions. This impacts not only the cost of and access to liquidity, but also other costs to run and invest in our business.

Other global economic events, such as accommodative monetary and fiscal policy, supply chain disruptions and geopolitical tensions beyond the aforementioned ongoing wars, contributed to significant inflation across the globe. In particular, inflation in the United States, Europe and other geographies has risen to levels not experienced in recent decades, and while this has eased somewhat in the last year, we are seeing its impact on various aspects of our business. Moreover, U.S. and global economic conditions have created market uncertainty and volatility. Such general economic conditions, including inflation, stagflation, political volatility, costs of labor, cost of capital, interest rates, bank stability, credit availability and tax rates, affect our cost of doing 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, including revenue from customers as well as income from funds we hold on behalf of customers and pension-related income.

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 this Annual Report on Form 10-K for a discussion of risks that may affect, among other things, our growth relative to expectation and our ability to achieve our objectives.

Transformation Program

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 — includes costs to align the real estate footprint to our new ways of working (hybrid work) and includes breakage fees and the impairment of right-of-use assets and other related leasehold assets.

Technology modernization — these charges are incurred in moving to common platforms and technologies, including migrating certain platforms and applications to the cloud. This category includes the impairment of technology assets that are duplicative or no longer revenue-producing, as w

Financial Risk Management

We are exposed to market risk from changes in foreign currency exchange rates. In order to manage the risk arising from these exposures, we enter into a variety of foreign currency derivatives. We do not hold financial or derivative instruments for trading purposes.

A discussion of our accounting policies for financial and derivative instruments is included in Note 2 — Basis of Presentation, Significant Accounting Policies and Recent Accounting Pronouncements and Note 10 — Derivative Financial Instruments within Item 8 of this Annual Report on Form 10-K.

Foreign Exchange Risk

Because of the large number of countries and currencies we operate in, movements in currency exchange rates may affect our results.

We report our operating results and financial condition in U.S. dollars. Our U.S. operations earn revenue and incur expenses primarily in U.S. dollars. Outside the U.S., we predominantly generate revenue and expenses in the local currency with the exception of our London market operations which earn revenue in several currencies but incur expenses predominantly in Pounds sterling.

The table below gives an approximate analysis of revenue and expenses from continuing operations by currency in 2024.

(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 and transaction and transformation.

Our principal exposures to foreign exchange risk arise from:

our London market operations;

intercompany lending between subsidiaries; and

translation.

London market operations

The Company’s primary foreign exchange risks in its London market operations arise from changes in the exchange rate between the U.S. dollar and Pound sterling as its London market operations earn the majority of its revenue in U.S. dollars but incur expenses predominantly in Pounds sterling and may also hold significant foreign currency asset or liability positions on its consolidated balance sheet. In addition, the London market operations earn significant revenue in Euros.

The foreign exchange risks in our London market operations are hedged to the extent that:

forecasted Pounds sterling expenses exceed Pounds sterling revenue, in which case the Company limits its exposure to this exchange rate risk by the use of forward and option contracts matched to a portion of the forecasted Pounds sterling outflows arising in the ordinary course of business. In addition, we are also exposed to foreign exchange risk on any net non-dollar asset or liability positions on our London market operations' balance sheets; and

the U.K. operations also earn significant revenue in Euros. The Company limits its exposure to changes in the exchange rates between the U.S. dollar and Euros by the use of foreign exchange contracts matched to a proportion of forecast revenue inflows in these specific currencies and periods.

Intercompany lending between subsidiaries

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 December 31, 2024, we had notional amounts of $1.2 billion (denominated primarily in U.S. dollars, Pounds sterling and Euros), with a net fair value liability of $3 million. Such derivatives typically mature within three months.

Translation risk

Outside our U.S. and London market operations, we predominantly earn revenue and incur expenses in the local currency. When we translate the results and net assets of these operations into U.S. dollars for reporting purposes, movements in exchange rates will affect reported results and net assets. For example, if the U.S. dollar strengthens against the Euro, the reported results of our Eurozone operations in U.S. dollar terms will be lower.

The table below provides information about our foreign currency forward exchange and option contracts which are designated as hedging instruments and are sensitive to exchange rate risk. The table summarizes the U.S. dollar equivalent amounts of each currency bought and sold forward and the weighted-average contractual exchange rates. All forward exchange contracts mature within two years.

(i)

Represents the difference between the contract amount and the cash flow in U.S. dollars which would have been receivable had the foreign currency forward exchange contracts been entered into on December 31, 2024 at the forward exchange rates prevailing at that date.

Income earned within foreign subsidiaries outside of the U.K. is generally offset by expenses in the same local currency, however the Company does have exposure to foreign exchange movements on the net income of these entities.

Interest Rate Risk

The Company has access to $1.5 billion under a revolving credit facility (see Note 11 — Debt within Item 8 of this Annual Report on Form 10-K for further information). As of December 31, 2024, no amount was drawn on this facility. We are also subject to market risk from exposure to changes in interest rates based on our investing activities where our primary interest rate risk arises from changes in short-term interest rates in U.S. dollars, Pounds sterling and Euros.

The table below provides information about our financial instruments that are sensitive to changes in interest rates. The Company had no outstanding floating rate-based debt at December 31, 2024.

(i)

Represents the net present value of the expected cash flows discounted at current market rates of interest or quoted market rates as appropriate.

Interest Income on Fiduciary Funds

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 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 increase in interest income in 2024 reflects a combination of relatively high average interest rates over the course of 2024 and some increases in our invested cash balances. 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 $166 million, $145 million and $55 million for the years ended December 31, 2024, 2023 and 2022, respectively. At December 31, 2024, we held $2.6 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 $6 million on an annualized basis.

Credit Risk and Concentrations of Credit Risk

Credit risk represents the loss that would be recognized at the reporting date if counterparties failed to perform as contracted. The Company currently does not anticipate non-performance by its counterparties. The Company generally does not require collateral or other security to support financial instruments with credit risk.

Concentrations of credit risk that arise from financial instruments exist for groups of customers or counterparties when they have similar economic characteristics that would cause their ability to meet contractual obligations to be similarly affected by changes in economic or other conditions. Financial instruments on the balance sheet that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, fiduciary funds, accounts receivable and derivatives which are recorded at fair value.

The Company maintains a policy of providing for the diversification of cash and cash equivalent investments and places such investments in an extensive number of financial institutions to limit the amount of credit risk exposure. These financial institutions are monitored on an ongoing basis for credit quality predominantly using information provided by credit agencies.

Concentrations of credit risk with respect to receivables are limited due to the large number of clients and markets in which the Company does business, as well as the dispersion across many geographic areas. Management does not believe that significant risk exists in connection with the Company’s concentrations of credit as of December 31, 2024.

WILLIS TOWERS WATSON PUBLIC LIMITED COMPANY

INDEX TO FORM 10-K

For the year ended December 31, 2024

REPORT OF INDEPENDENT REGIST****ERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Willis Towers Watson Public Limited Company

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Willis Towers Watson Public Limited Company and subsidiaries (the ‘Company’) as of December 31, 2024 and 2023, the related consolidated statements of comprehensive income, changes in equity and cash flows, for each of the three years in the period ended December 31, 2024, and the related notes (collectively referred to as the ‘financial statements’). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America (‘US GAAP’).

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (‘PCAOB’), the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2025, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Provisions for Liabilities - Errors & Omissions Reserve — Refer to Notes 2, 15 and 16 to the financial statements

Critical Audit Matter Description

The Company has established provisions against various actual and potential claims, lawsuits and other proceedings relating principally to alleged errors and omissions (‘E&O’) which arise in connection with the placement of insurance and reinsurance and provision of broking, consulting and outsourcing services in the ordinary course of business. Such provisions cover claims that have been reported but not paid and also claims that have been incurred but not reported (‘IBNR’). These provisions are established based on actuarial estimates together with individual case reviews. Significant management judgment is required to estimate the amounts of such claims.

Auditing management’s judgments related to its E&O provision, and in particular the broking, consulting and outsourcing business provisions related to the IBNR, and the provisions related to significant claims reported but not paid, involved especially complex and subjective judgment and an increased extent of effort, including the need to involve our actuarial specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the determination of E&O provisions included the following, among others:

We tested the effectiveness of controls over the Company’s estimation of the E&O provisions, including controls over the underlying historical claims data, the actuarial methodology used, the assumptions selected by management that are used to calculate the broking, consulting and outsourcing business IBNR provisions, and the establishment and quarterly evaluation of provisions for reported claims, including significant claims.

For the IBNR provisions, we evaluated the appropriateness of the IBNR models, and evaluated the consistency of the model with prior years in order to challenge the methodology used to estimate the provisions. With the assistance of our actuarial specialists, we assessed the methodology and models used, including key inputs and assumptions used in, and arithmetical accuracy of, the models used. We also performed retrospective reviews of management’s estimated claims emergence in comparison to actual results and evaluated the provisions set by management in comparison to a range of independent estimates that we developed.

We evaluated the E&O matters and the appropriateness of their projected settlement values through inquiries of, and confirmations from, in-house counsel and external lawyers handling those matters for the Company.

Evaluation of Disclosure Controls and Procedures

An evaluation was performed under the supervision and with the participation of our chief executive officer (‘CEO’) and chief financial officer (‘CFO’), of the effectiveness of the design and operation of our 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’), as of the end of the period covered by this Annual Report on Form 10-K. Based upon that evaluation, our management, including the CEO and CFO, concluded that our disclosure controls and procedures were effective as of December 31, 2024 in providing reasonable assurance that the information required to be disclosed 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 in the quarter and year ended December 31, 2024 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Internal control over financial reporting refers to the process designed by, or under the supervision of, our CEO and CFO, and overseen by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles (‘U.S. GAAP’), and includes those policies and procedures that:

(1)

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

(2)

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

(3)

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting can also be circumvented by collusion or improper management override. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

Management is responsible for establishing and maintaining the adequacy and effectiveness of our internal control over financial reporting. Under the supervision and with the participation of our management, including our CEO and CFO, we evaluated the effectiveness of our internal control over financial reporting as of December 31, 2024. In making this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in the report entitled Internal Control — Integrated Framework (2013). Based on this evaluation, management has concluded that we maintained effective internal control over financial reporting as of December 31, 2024.

The effectiveness of our internal control over financial reporting has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report titled ‘Report of Independent Registered Public Accounting Firm on Internal Control over Financial Reporting,’ which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Willis Towers Watson Public Limited Company

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Willis Towers Watson Public Limited Company and subsidiaries (the ‘Company’) as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (‘COSO’). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (‘PCAOB’), the consolidated financial statements as of and for the year ended December 31, 2024, of the Company and our report dated February 25, 2025, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
