Aon Reports Third-Quarter 2026 Results

Open on SEC ↗

October 28, 2026 - Aon plc (NYSE: AON) today reported results for the three months ended September 30, 2026.

• Aon delivered another quarter of strong performance, including 3% total revenue growth, 6% organic revenue growth and EPS growth. Our results showcased broad-based strength across solution lines, with organic revenue growth of 7% in Commercial Risk, 7% in Reinsurance, 6% in Health and 4% in Wealth

• Our disciplined capital allocation framework is supported by strong free cash flow generation. We expect the USI Acquisition to close in the fourth quarter of 2026, and will prioritize debt repayment with a path towards deleveraging to our 2.8x-3.0x objective in approximately 24 months

• We enter the fourth quarter with significant momentum, reinforcing our confidence in our ability to deliver strong financial performance for full-year 2026

“Our Aon United strategy continues to advance and differentiate our platform for clients” said Greg Case, president and CEO. “As we progress through the final year of our 3x3 Plan, our investments in AI-enabled analytics, innovative capabilities and capital solutions, and leading experts are helping clients address their risks, build resilience and drive better outcomes. At the same time, we are strengthening our context advantage and expanding our ability to serve clients across a broader market through the announced acquisition of USI, while creating new opportunities through greater access to both traditional and alternative sources of capital.”

Case added: “The impact of this strategy is further demonstrated by our strong third-quarter results with 6% organic revenue growth, 70 basis points of adjusted margin expansion and 10% adjusted EPS growth. We enter the fourth quarter with significant momentum, reinforcing confidence in our ongoing ability to deliver sustained, differentiated performance.”

in the third quarter increased 6%, to $2.23 per share on a diluted basis, compared to $2.11 per share on a diluted basis, in the prior-year period. Adjusted net income per share attributable to Aon shareholders increased 10% to $3.36 on a diluted basis, including a $0.02 favorable impact if prior-year period results were translated at current-period foreign exchange rates ("foreign currency translation”), compared to $3.05 in the prior-year period. Certain items that impacted third-quarter results and comparisons with the prior-year period are detailed in “Reconciliation of Non-GAAP Measures - Operating Income and Operating Margin (Unaudited)” and “Reconciliation of Non- GAAP Measures - Diluted Earnings Per Share (Unaudited)” beginning on page 11 of this press release.

in the third quarter increased 3% to $4.1 billion compared to the prior-year period, reflecting 6% organic revenue growth, partially offset by a 3% unfavorable impact primarily from divestitures. Risk Capital revenue increased $157 million, or 6%, to $2.7 billion and Human Capital revenue decreased $54 million, or 4%, to $1.4 billion.

in the third quarter increased 3% to $3.3 billion compared to the prior-year period due primarily to an increase in expense associated with 6% organic revenue growth, investments in long-term growth, and an increase in Accelerating Aon United Program expenses, partially offset by lower expenses associated with the sale of the NFP Wealth business and $20 million of net restructuring savings. Risk Capital operating expenses increased $134 million, or 7%, and Human Capital operating expenses decreased $68 million, or 6%.

translation had a $0.02 favorable impact on both diluted EPS and adjusted EPS in the third quarter. If currency were to remain stable at today’s rates, the Company would expect a de minimis impact on adjusted EPS in the fourth quarter of 2026 and a favorable impact on adjusted EPS of approximately $0.42 per share for the full year 2026.

was 20.6% in the third quarter compared to 21.3% 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 third quarter of 2026 was 20.2% compared to 19.2% in the prior-year period. The primary drivers of the change in the effective tax rate were changes to the geographical distribution of income and a greater net unfavorable impact from discrete items. The primary drivers of the change in the adjusted effective tax rate were changes to the geographical distribution of income and a net unfavorable impact from discrete items.

decreased to 213.0 million in the third quarter compared to 216.7 million in the prior-year period. The Company did not repurchase any shares in the third quarter. As of September 30, 2026, the Company had approximately $7.7 billion of remaining authorization under its share repurchase program.

for the first nine months of 2026 increased $93 million, or 4%, to $2.2 billion compared to the prior-year period, as strong adjusted operating income growth offset the impact of working capital and USI-related transaction costs. 2

, defined as cash flow from operations less capital expenditures, increased 3%, to $1.9 billion for the first nine months of 2026 compared to the prior-year period, reflecting an increase in cash flows provided by operations, partially offset by a $45 million increase in capital expenditures.

The third-quarter revenue reviews provided below include supplemental information related to organic revenue growth, 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.

Total revenue increased $104 million, or 3%, compared to the prior-year period, reflecting 6% organic revenue growth, driven by net new business and ongoing strong retention, partially offset by a 3% unfavorable impact primarily from divestitures largely due to the sales of the NFP Wealth business and Stroz Friedberg. Risk Capital revenue increased $157 million, or 6%, and Human Capital revenue decreased $54 million, or 4%.

Commercial Risk Solutions Organic revenue growth of 7% reflects strong growth in North America and EMEA, driven by net new business and ongoing strong retention. Net market impact was slightly positive. Within North America, performance was highlighted by strong growth in M&A services and U.S. core P&C, and growth in construction.

Reinsurance Solutions Organic revenue growth of 7% reflects strong growth in treaty placements, driven by net new business and strong retention, and a favorable impact from the reversal of the constraint applied against prior period revenue. Net market impact was unfavorable in the quarter.

Health Solutions Organic revenue growth of 6% reflects strong growth in core health and benefits, including particular strength internationally, driven by net new business and ongoing strong retention, as well as growth in Talent Solutions driven by talent analytics. Net market impact was modestly positive.

Wealth Solutions Organic revenue growth of 4% reflects strong growth in Retirement, driven by continued demand for advisory work in the UK and EMEA related to the ongoing impact of regulatory change. 3

expense increased $16 million, or 1%, compared to the prior-year period, due primarily to higher expenses associated with 6% organic revenue growth and investments in long-term growth, partially offset by lower expenses from the sale of the NFP Wealth business and savings from Accelerating Aon United restructuring actions.

expense increased $16 million, or 11%, compared to the prior-year period, due primarily to Aon Business Services investments in ongoing technology initiatives.

expense decreased $2 million, or 2%, compared to the prior-year period, as we continued to optimize our real estate footprint and recognize savings from Accelerating Aon United restructuring actions.

decreased $18 million, or 9%, compared to the prior-year period, due primarily to the decrease in intangible assets associated with the sale of the NFP Wealth business.

increased $36 million, or 8%, compared to the prior-year period, due primarily to a recovery in the prior-year period associated with a legal settlement as well as USI-related transaction costs.

Accelerating Aon United Restructuring Program expense increased $61 million, or 191%, compared to the prior-year period, due primarily to costs related to workforce optimization. 4

Certain noteworthy items impacted adjusted operating income and adjusted operating margin in the third quarters of 2026 and 2025, which are also described in detail in “Reconciliation of Non-GAAP Measures - Operating Income and Operating Margin (Unaudited)” and “Reconciliation of Non-GAAP Measures - Diluted Earnings Per Share (Unaudited)” on page 11 of this press release.

increased 70 basis points to 27.0%, each compared to the prior-year period. The increase in adjusted operating income reflects organic revenue growth, scale improvements in ABS and net restructuring savings, partially offset by investments for growth.

increased $24 million compared to the prior-year period, primarily reflecting higher cash balances as a result of the net proceeds raised from debt issuance.

was flat compared to the prior-year period. Lower average debt balances during much of the quarter were offset by interest expense associated with debt issued near the end of the quarter to fund the USI Acquisition.

were $15 million compared to $13 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.

increased 4% to $476 million compared to $458 million in the prior-year period. Adjusted net income attributable to Aon shareholders increased 8% to $715 million compared to $660 million in the prior-year period.

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 pending USI Acquisition, 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 USI are forward-looking statements. Also, when Aon uses words such as “anticipate”, “believe”, “continue”, “confidence”, “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; Aon’s global tax rate being subject to a variety of different factors, including the application of the OECD’s Pillar Two tax regime by Ireland, the U.K., Singapore, and many E.U. member states, among others, 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 or related to acquisition or disposition transactions, errors and omissions and other claims against Aon (including proceedings 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, including but not limited to in the areas of cybersecurity, data privacy and artificial intelligence; 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, sanctions, 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 pending acquisition of USI (including anticipated revenue and growth synergies) in the expected timeframe, or at all; significant transaction and integration costs or difficulties in connection with the pending acquisition of USI or unknown or inestimable liabilities; and the potential impact of the consummation of the pending USI Acquisition on relationships, including with suppliers, customers, employees and regulators. 6 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, 2025 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.

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 net income, adjusted net income attributable to Aon shareholders, adjusted diluted net income per share (“EPS”), adjusted effective tax rate, adjusted other income (expense), adjusted income tax expense, leverage ratio, and adjusted income before income taxes that exclude the effects of intangible asset amortization and impairment, Accelerating Aon United Program expenses, contingent consideration, NFP integration costs, USI transaction 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, which are adjusted from organic revenue growth upon classification as held-for-sale), 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. Leverage ratio is calculated by dividing total debt by trailing 12-month EBITDA. EBITDA is net income minus the impact of interest, taxes, depreciation and amortization, and the non-recurring gain from the sale of the substantial majority of NFP's Wealth business. 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 certain of 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 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, such as adjusted operating margin, adjusted other income (expense) and adjusted effective tax rate, and leverage ratio 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 Aon's control, or cannot be reasonably predicted. For these reasons, Aon is also unable to address the probable significance of the unavailable information.

“Our Aon United strategy continues to advance and differentiate our platform for
clients” said Greg Case, president and CEO. “As we progress through the final
year of our 3x3 Plan, our investments in AI-enabled analytics, innovative
capabilities and capital solutions, and leading experts are helping clients
address their risks, build resilience and drive better outcomes. At the same
time, we are strengthening our context advantage and expanding our ability to
serve clients across a broader market through the announced acquisition of USI,
while creating new opportunities through greater access to both traditional and
alternative sources of capital.”

Case added: “The impact of this strategy is further demonstrated by our strong
third-quarter results with 6% organic revenue growth, 70 basis points of
adjusted margin expansion and 10% adjusted EPS growth. We enter the fourth
quarter with significant momentum, reinforcing confidence in our ongoing ability
to deliver sustained, differentiated performance.”

in the third quarter increased 3% to $4.1 billion compared to the prior-year
period, reflecting 6% organic revenue growth, partially offset by a 3%
unfavorable impact primarily from divestitures. Risk Capital revenue increased
$157 million, or 6%, to $2.7 billion and Human Capital revenue decreased $54
million, or 4%, to $1.4 billion.

in the third quarter increased 3% to $3.3 billion compared to the prior-year
period due primarily to an increase in expense associated with 6% organic
revenue growth, investments in long-term growth, and an increase in Accelerating
Aon United Program expenses, partially offset by lower expenses associated with
the sale of the NFP Wealth business and $20 million of net restructuring
savings. Risk Capital operating expenses increased $134 million, or 7%, and
Human Capital operating expenses decreased $68 million, or 6%.

translation had a $0.02 favorable impact on both diluted EPS and adjusted EPS in
the third quarter. If currency were to remain stable at today’s rates, the
Company would expect a de minimis impact on adjusted EPS in the fourth quarter
of 2026 and a favorable impact on adjusted EPS of approximately $0.42 per share
for the full year 2026.

was 20.6% in the third quarter compared to 21.3% 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 third quarter of 2026 was
20.2% compared to 19.2% in the prior-year period. The primary drivers of the
change in the effective tax rate were changes to the geographical distribution
of income and a greater net unfavorable impact from discrete items. The primary
drivers of the change in the adjusted effective tax rate were changes to the
geographical distribution of income and a net unfavorable impact from discrete
items.

decreased to 213.0 million in the third quarter compared to 216.7 million in the
prior-year period. The Company did not repurchase any shares in the third

Total revenue increased $104 million, or 3%, compared to the prior-year period,
reflecting 6% organic revenue growth, driven by net new business and ongoing
strong retention, partially offset by a 3% unfavorable impact primarily from
divestitures largely due to the sales of the NFP Wealth business and Stroz
Friedberg. Risk Capital revenue increased $157 million, or 6%, and Human Capital
revenue decreased $54 million, or 4%.

Commercial Risk Solutions Organic revenue growth of 7% reflects strong growth in
North America and EMEA, driven by net new business and ongoing strong retention.
Net market impact was slightly positive. Within North America, performance was
highlighted by strong growth in M&A services and U.S. core P&C, and growth in
construction.

Reinsurance Solutions Organic revenue growth of 7% reflects strong growth in
treaty placements, driven by net new business and strong retention, and a
favorable impact from the reversal of the constraint applied against prior
period revenue. Net market impact was unfavorable in the quarter.

Health Solutions Organic revenue growth of 6% reflects strong growth in core
health and benefits, including particular strength internationally, driven by
net new business and ongoing strong retention, as well as growth in Talent
Solutions driven by talent analytics. Net market impact was modestly positive.

Wealth Solutions Organic revenue growth of 4% reflects strong growth in
Retirement, driven by continued demand for advisory work in the UK and EMEA
related to the ongoing impact of regulatory change.

191%, compared to the prior-year period, due primarily to costs related to

decreased 70 basis points to 19.7%, each compared to the prior-year period.

increased 70 basis points to 27.0%, each compared to the prior-year period. The
increase in adjusted operating income reflects organic revenue growth, scale
improvements in ABS and net restructuring savings, partially offset by
investments for growth.

increased $24 million compared to the prior-year period, primarily reflecting
higher cash balances as a result of the net proceeds raised from debt issuance.

was flat compared to the prior-year period. Lower average debt balances during
much of the quarter were offset by interest expense associated with debt issued
near the end of the quarter to fund the USI Acquisition.

were $15 million compared to $13 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.

increased 4% to $476 million compared to $458 million in the prior-year period.
Adjusted net income attributable to Aon shareholders increased 8% to $715

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 pending USI Acquisition, 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
USI are forward-looking statements. Also, when Aon uses words such as
“anticipate”, “believe”, “continue”, “confidence”, “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; Aon’s global tax
rate being subject to a variety of different factors, including the application
of the OECD’s Pillar Two tax regime by Ireland, the U.K., Singapore, and many
E.U. member states, among others, 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 or related to acquisition or disposition transactions, errors and omissions
and other claims against Aon (including proceedings 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,
including but not limited to in the areas of cybersecurity, data privacy and
artificial intelligence; 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, sanctions, 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 pending
acquisition of USI (including anticipated revenue and growth synergies) in the
expected timeframe, or at all; significant transaction and integration costs or
difficulties in connection with the pending acquisition of USI or unknown or
inestimable liabilities; and the potential impact of the consummation of the
pending USI Acquisition on relationships, including with suppliers, customers,
employees and regulators.
                                       6                                        
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, 2025 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 net income, adjusted net
income attributable to Aon shareholders, adjusted diluted net income per share
(“EPS”), adjusted effective tax rate, adjusted other income (expense), adjusted
income tax expense, leverage ratio, and adjusted income before income taxes that
exclude the effects of intangible asset amortization and impairment,
Accelerating Aon United Program expenses, contingent consideration, NFP
integration costs, USI transaction 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, which are adjusted from
organic revenue growth upon classification as held-for-sale), 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. Leverage ratio is
calculated by dividing total debt by trailing 12-month EBITDA. EBITDA is net
income minus the impact of interest, taxes, depreciation and amortization, and
the non-recurring gain from the sale of the substantial majority of NFP's Wealth
business. 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 certain of 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 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, such as
adjusted operating margin, adjusted other income (expense) and adjusted
effective tax rate, and leverage ratio 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 Aon's control, or cannot be reasonably predicted. For these reasons,
Aon is also unable to address the probable significance of the unavailable
information.
