We closed the year with another strong quarter of performance and delivered an outstanding full year 2024, with 6% Organic revenue growth, strong margins, double-digit adjusted EPS growth and $2.8 billion of Free Cash Flow, with NFP performing inline or better than our business case
We are introducing 2025 guidance that positions Aon to continue its long-term track record of delivering mid-single-digit or greater Organic revenue growth, adjusted margin expansion, strong adjusted EPS growth and double-digit Free Cash Flow growth
Our 2025 Free Cash Flow generation is expected to enable us to execute our capital allocation model, including meeting our leverage objective in Q4'25, investing in organic growth and tuck-in M&A, and returning capital to shareholders, including $1 billion in share repurchases

"We ended 2024 with another quarter of strong performance and outstanding execution across all aspects of our strategy," said Greg Case, CEO. "We generated 6% Organic revenue growth for the fourth quarter and full year, with mid-single digit growth or better across all our solution lines. This top-line strength and continued cost efforts drove strong margins, double-digit EPS growth, and $2.8 billion of free cash flow. As expected, executing our 3x3 Plan creates differentiation in how we serve our clients across Risk Capital and Human Capital, powered by Aon Business Services. As clients navigate increasingly complex market dynamics, demand for our solutions remains strong. We are well-positioned to build on our momentum in 2025 and drive long-term value creation for our colleagues, clients and shareholders."

Net income attributable to Aon shareholders in the fourth quarter increased 44%, or $3.28 per share on a diluted basis, compared to $2.47 per share on a diluted basis, in the prior year period. Adjusted net income per share attributable to Aon shareholders increased 14% to $4.42 on a diluted basis for the quarter, including an unfavorable impact of $0.07 per share if prior year period results were translated at current period foreign exchange rates ("foreign currency translation"), compared to $3.89 in the prior year. Certain items that impacted fourth quarter results and comparisons with the prior year period are detailed in "Reconciliation of Non-GAAP Measures - Operating Income, Operating Margin, and Diluted Earnings Per Share" on page 11 of this press release.

FOURTH QUARTER 2024 FINANCIAL SUMMARY

Beginning in the fourth quarter, the Company realigned from a single reporting segment to two: Risk Capital and Human Capital. This segmentation will align with how the Company addresses client needs, accelerating its Aon United strategy and maximizing value for Aon and its shareholders. Risk Capital is comprised of Commercial Risk Solutions and Reinsurance Solutions, while Human Capital is comprised of Health Solutions and Wealth Solutions.

Total revenue in the fourth quarter increased 23% to $4.1 billion compared to the prior year period reflecting acquired revenues from NFP and 6% Organic revenue growth, partially offset by a 1% unfavorable impact from foreign currency translation. Risk Capital revenue increased $299 million, or 13%, to $2.5 billion and Human Capital revenue increased $472 million, or 41% to $1.6 billion.

Total operating expenses in the fourth quarter increased 18% to $3.1 billion compared to the prior year period due primarily to the inclusion of NFP's ongoing operating expenses, an increase in expense associated with 6% Organic revenue growth, an increase in intangible asset amortization associated with the acquisition of NFP and investments in long-term growth, partially offset by a non-recurring charge in connection with certain settlement expenses in the prior year period and $40 million of restructuring savings realized in the quarter. Risk Capital operating expenses increased $88 million, or 5%, to $1.8 billion and Human Capital operating expenses increased $376 million, or 49%, to $1.1 billion.

Foreign currency translation in the fourth quarter had a $14 million, or $0.06 per share, unfavorable impact on U.S. GAAP net income and a $14 million, or $0.07 per share, unfavorable impact on adjusted net income. If currency were to remain stable at today's rates, the Company would expect an unfavorable impact of approximately $0.16 per share, or an approximately $48 million decrease in adjusted operating income, in the first quarter of 2025, and an unfavorable impact of approximately $0.32 per share, or an approximately $96 million decrease in adjusted operating income, for full year 2025.

Effective tax rate for the fourth quarter was 17.6%, compared to 16.7% in the prior year period, primarily driven by changes in the geographical distribution of income. After adjusting to exclude the applicable tax impact associated with certain non-GAAP adjustments, the adjusted effective tax rate for the fourth quarter of 2024 was 16.7% compared to 18.2% in the prior year period. The primary drivers of the change in the adjusted effective tax rate were the changes in the geographical distribution of income and a net favorable impact from discrete items.

Weighted average diluted shares outstanding increased to 218.3 million in the fourth quarter compared to 202.0 million in the prior year period due to the issuance of 19.0 million shares in the second quarter of 2024 to fund the NFP acquisition. The Company repurchased 0.6 million class A ordinary shares for approximately $200 million in the fourth quarter. As of December 31, 2024, the Company had approximately $2.3 billion of remaining authorization under its share repurchase program.

FULL YEAR 2024 CASH FLOW SUMMARY

The full year 2024 cash flow summary provided below includes supplemental information related to free cash flow, which is a non-GAAP measure that is described in detail in "Reconciliation of Non-GAAP Measures - Organic Revenue Growth and Free Cash Flow" on page 10 of this press release.

Cash flows provided by operations for 2024 decreased $400 million, or 12%, to $3.0 billion compared to the prior year period, primarily due to higher cash taxes, and payments related to restructuring, legal settlement expenses, transaction and integration costs, partially offset by strong adjusted operating income growth and working capital improvements.

Free cash flow, defined as cash flow from operations less capital expenditures, decreased 11%, to $2.8 billion in 2024 compared to the prior year, reflecting a decrease in cash flows from operations, partially offset by a $34 million decrease in capital expenditures as spend in the prior year was elevated.

The following factors, among others, could cause actual results to differ from those set forth in or anticipated by the forward looking statements: changes in the competitive environment, due to macroeconomic conditions (including impacts from instability in the banking or commercial real estate sectors) or otherwise, or damage to Aon's reputation; fluctuations in currency exchange, interest, or inflation rates that could impact our financial condition or results; changes in global equity and fixed income markets that could affect the return on invested assets; changes in the funded status of Aon's various defined benefit pension plans and the impact of any increased pension funding resulting from those changes; the level of Aon's debt and the terms thereof reducing Aon's flexibility or increasing borrowing costs; rating agency actions that could limit Aon's access to capital and our competitive position; volatility in Aon's global tax rate due to being subject to a variety of different factors, including the adoption and implementation in the European Union, the United States, the United Kingdom, or other countries of the Organization for Economic Co-operation and Development tax proposals or other pending proposals in those and other countries, which could create volatility in that tax rate; changes in Aon's accounting estimates or assumptions on Aon's financial statements; limits on Aon's subsidiaries' ability to pay dividends or otherwise make payments to Aon; the impact of legal proceedings and other contingencies, including those arising from acquisition or disposition transactions, errors and omissions and other claims against Aon (including proceeding and contingencies relating to transactions for which capital was arranged by Vesttoo Ltd. or related to actions we may take in being responsible for making decisions on behalf of clients in our investment business or in other advisory services that we currently provide, or may provide in the future); the impact of, and potential challenges in complying with, laws and regulations in the jurisdictions in which Aon operates, particularly given the global nature of Aon's operations and the possibility of differing or conflicting laws and regulations, or the application or interpretation thereof, across jurisdictions in which Aon does business; the impact of any regulatory investigations brought in Ireland, the U.K., the U.S. and other countries; failure to protect intellectual property rights or allegations that Aon infringes on the intellectual property rights of others; general economic and political conditions in different countries in which Aon does business around the world; the failure to retain, attract and develop experienced and qualified personnel; international risks associated with our global operations, including impacts from military conflicts or political instability, such as the ongoing Russian war in Ukraine and the conflicts in the Middle East; the effects of natural or human-caused disasters, including the effects of health pandemics and the impacts of climate related events; any system or network disruption or breach resulting in operational interruption or improper disclosure of confidential, personal, or proprietary data, and resulting liabilities or damage to our reputation; Aon's ability to develop, implement, update and enhance new technology; the actions taken by third parties that perform aspects of Aon's business operations and client services; Aon's ability to continue, and the costs and risks associated with, growing, developing and integrating acquired business, and entering into new lines of business or products; Aon's ability to secure regulatory approval and complete transactions, and the costs and risks associated with the failure to consummate proposed transactions; changes in commercial property and casualty markets, commercial premium rates or methods of compensation; Aon's ability to develop and implement innovative growth strategies and initiatives intended to yield cost savings (including the Accelerating Aon United Program), and the ability to achieve such growth or cost savings; the effects of Irish law on Aon's operating flexibility and the enforcement of judgments against Aon; adverse effects on the market price of Aon's securities and/or operating results for any reason, including, without limitation, because of a failure to realize the expected benefits of the acquisition of NFP (including anticipated revenue and growth synergies) in the expected timeframe, or at all; significant integration costs or difficulties in connection with the acquisition of NFP or unknown or inestimable liabilities; and potential impact of the consummation of the acquisition of NFP on relationships, including with suppliers, customers, employees and regulators.

Any or all of Aon's forward-looking statements may turn out to be inaccurate, and there are no guarantees about Aon's performance. The factors identified above are not exhaustive. Aon and its subsidiaries operate in a dynamic business environment in which new risks may emerge frequently. Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of the dates on which they are made. In addition, results for prior periods are not necessarily indicative of results that may be expected for any future period. Further information concerning Aon and its businesses, including factors that could materially affect Aon's financial results, is contained in Aon's filings with the SEC. See Aon's Annual Report on Form 10-K for the year ended December 31, 2023 and the risk factors set forth under the headings "Risks Related to Aon and the NFP business after Completion of the Transaction" and "Risks Related to NFP's Business" in Aon's registration statement on Form S-4 filed on April 23, 2024 for a further discussion of these and other risks and uncertainties applicable to Aon and its businesses. These factors may be revised or supplemented in subsequent reports filed with the SEC. Aon is not under, and expressly disclaims, any obligation to update or alter any forward-looking statement that it may make from time to time, whether as a result of new information, future events or otherwise.

Explanation of Non-GAAP Measures

This communication includes supplemental information not calculated in accordance with generally accepted accounting principles in the United States ("U.S. GAAP"), including Organic revenue growth, free cash flow, free cash flow margin, adjusted operating income, adjusted operating margin, adjusted earnings per share, adjusted net income attributable to Aon shareholders, adjusted diluted net income per share, adjusted effective tax rate, adjusted other income (expense), and adjusted income before income taxes that exclude the effects of intangible asset amortization and impairment, Accelerating Aon United Program expenses, contingent consideration, NFP transaction and integration costs, certain pension settlements, capital expenditures, and certain other noteworthy items that affected results for the comparable periods. Organic revenue growth includes the impact of intercompany activity and excludes foreign exchange rate changes, acquisitions (provided that Organic revenue growth includes Organic growth of an acquired business as calculated assuming that the acquired business was part of the combined company for the same proportion of the relevant prior year period), divestitures (including held for sale disposal groups, if any), transfers between revenue lines, fiduciary investment income, and gains or losses on derivatives accounted for as hedges. Currency impact represents the effect on prior year period results if they were translated at current period foreign exchange rates. Reconciliations to the closest U.S. GAAP measure for each non-GAAP measure presented in this communication are provided in the attached appendices. Supplemental Organic revenue growth information and additional measures that exclude the effects of certain items noted above do not affect net income or any other U.S. GAAP reported amounts. Free cash flow is cash flows from operating activity less capital expenditures. The adjusted effective tax rate excludes the applicable tax impact associated with adjustments previously described, generally at the estimated annual effective tax rate or jurisdictional rate, where appropriate. Beginning in the third quarter of 2024, the adjusted effective tax rate also excludes interest accruals for income tax reserves related to the termination fee payment made in connection with the Company's terminated proposed combination with Willis Towers Watson. Management believes that these measures are important to make meaningful period-to-period comparisons and that this supplemental information is helpful to investors. Management also uses these measures to assess operating performance and performance for compensation. Non-GAAP measures should be viewed in addition to, not in lieu of, Aon's Condensed Consolidated Financial Statements. Industry peers provide similar supplemental information regarding their performance, although they may not make identical adjustments.
