Adjusted net income per share attributable to Aon shareholders increased 19% to $3.49 on a diluted basis compared to $2.93 in the prior year period. Certain items that impacted second 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.

SECOND QUARTER 2025 FINANCIAL SUMMARY

Total revenue in the second quarter increased 11% to $4.2 billion compared to the prior year period, reflecting 6% organic revenue growth, the contribution from NFP and 1% favorable impact from foreign currency translation. Risk Capital revenue increased $216 million, or 8%, to $2.9 billion and Human Capital revenue increased $166 million, or 15%, to $1.3 billion.

Total operating expenses in the second quarter increased 6% to $3.3 billion compared to the prior year period due primarily to the inclusion of NFP's ongoing operating expenses, an increase in intangible asset amortization associated with the NFP acquisition and an increase in expense associated with 6% organic revenue growth and investments in long-term growth, partially offset by transaction costs incurred in the prior year period, lower Accelerating Aon United program expense and $35 million of net restructuring savings. Risk Capital operating expenses increased $136 million, or 7%, to $2.0 billion and Human Capital operating expenses increased $139 million, or 13%, to $1.2 billion.

Foreign currency translation had a de minimis impact on EPS in the second quarter. If currency were to remain stable at today's rates, the Company would expect an unfavorable impact on adjusted EPS of approximately $0.05 per share for the full year 2025.

Effective tax rate was 15.5% in the second quarter compared to 22.9% in the prior year period. After adjusting to exclude the applicable tax impact associated with certain non-GAAP adjustments, the adjusted effective tax rate for the second quarter of 2025 was 16.5% compared to 22.2% in the prior year period. The primary drivers of the change in adjusted effective tax rate were the net favorable impact from discrete items and changes in the geographical distribution of income.

Weighted average diluted shares outstanding increased to 217.3 million in the second quarter compared to 213.3 million in the prior year period. The Company repurchased 0.7 million class A ordinary shares for approximately $250 million in the second quarter. As of June 30, 2025, the Company had approximately $1.8 billion of remaining authorization under its share repurchase program.

YEAR TO DATE 2025 CASH FLOW SUMMARY

Cash flows provided by operations for the first six months of 2025 increased $114 million, or 14%, to $936 million compared to the prior year period, primarily due to strong adjusted operating income growth and days sales outstanding improvements, partially offset by higher payments related to incentive compensation, interest, and restructuring.

Free cash flow, defined as cash flow from operations less capital expenditures, increased 13%, to $816 million for the first six months of 2025 compared to the prior year period, reflecting an increase in cash flows provided by operations, partially offset by a $19 million increase in capital expenditures.

Accelerating Aon United Restructuring Program expense decreased $38 million, or 29%, compared to the prior year period due to lower costs related to workforce optimization and asset impairments, partially offset by higher costs related to technology and other costs.

SECOND QUARTER 2025 INCOME SUMMARY

Certain noteworthy items impacted adjusted operating income and Adjusted operating margin in the second quarters of 2025 and 2024, which are also described in detail in "Reconciliation of Non-GAAP Measures - Operating Income, Operating Margin and Diluted Earnings Per Share" on page 11 of this press release.

	Three Months Ended June 30,
*(millions)*	2025	2024	% Change
Revenue	$ 4,155	$ 3,760	11 %
Expenses	3,296	3,104	6 %
Operating income	$ 859	$ 656	31 %
Operating margin	20.7 %	17.4 %
Adjusted operating income	$ 1,171	$ 1,029	14 %
Adjusted operating margin	28.2 %	27.4 %

Adjusted operating income increased $142 million, or 14%, and Adjusted operating margin increased 80 basis points to 28.2%, each compared to the prior year period. The increase in adjusted operating income reflects organic revenue growth, the impact from NFP, and net restructuring savings, partially offset by increased expenses and investments in long-term growth.

Interest income decreased $31 million compared to the prior year period due primarily to interest earned in the prior year period on the investment of $5 billion of term debt proceeds which were used to fund the purchase of NFP. Interest expense decreased $13 million compared to the prior year period, reflecting lower total debt.

Other income was $56 million compared to $236 million in the prior year period, primarily due to gains related to the sale of a business in the prior year period, partially offset by deferred consideration from the 2017 sale of our outsourcing business. Adjustedother expense was $32 million compared to $15 million in the prior year period, primarily due to the unfavorable impact of exchange rates on the remeasurement of assets and liabilities in non-functional currencies and an increase in non-cash pension expense.

Net income attributable to Aon shareholders increased 10% to $579 million compared to $524 million in the prior year period. Adjusted net income attributable to Aon shareholders increased 22% to $759 million compared to $624 million in the prior year period.

Safe Harbor Statement
This communication contains certain statements related to future results, or states Aon's intentions, beliefs and expectations or predictions for the future, all of which are forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from either historical or anticipated results depending on a variety of factors. These forward-looking statements include information about possible or assumed future results of Aon's operations. All statements, other than statements of historical facts, that address activities, events or developments that Aon expects or anticipates may occur in the future, including such things as our outlook, market and industry conditions, including competitive and pricing trends, the development and performance of our services and products, our cost structure and the outcome of cost-saving or restructuring initiatives, including the impacts of the Accelerating Aon United Program, the integration of NFP, actual or anticipated legal settlement expenses, future capital expenditures, growth in commissions and fees, changes to the composition or level of our revenues, cash flow and liquidity, expected tax rates, expected foreign currency translation impacts, business strategies, competitive strengths, goals, the benefits of new initiatives, growth of our business and operations, plans, references to future successes, and expectations with respect to the benefits of the acquisition of NFP are forward-looking statements. Also, when Aon uses words such as "anticipate", "believe", "continue", "could", "estimate", "expect", "forecast", "intend", "looking forward", "may", "might", "plan", "potential", "opportunity", "commit", "probably", "project", "positioned", "should", "will", "would" or similar expressions, it is making forward-looking statements.

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 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 geopolitical conflicts, tariffs, or changes in trade policies; 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; and significant integration costs or difficulties in connection with the acquisition of NFP or unknown or inestimable liabilities.

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, 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, adjusted operating income, adjusted operating margin, adjusted earnings per share (EPS), 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. Aon does not provide a reconciliation of forward-looking non-GAAP measures, where Aon believes such a reconciliation would imply a degree of precision and certainty that could be misleading and is unable to reasonably predict certain items contained in the corresponding GAAP measures without unreasonable efforts. This is due to the inherent difficulty of forecasting the timing or amount of various items that have not yet occurred and are out of the Aon's control, or cannot be reasonably predicted. For these reasons, Aon is also unable to address the probable significance of the unavailable information.
