“We delivered another outstanding quarter of operating performance!” said J. Patrick Gallagher, Jr., Chairman, President and CEO. “During the second quarter, our core brokerage and risk management segments combined to post 17% growth in revenue, of which 8.6% was organic revenue growth; net earnings margin improved by 106 basis points; and adjusted EBITDAC margins expanded by 30 basis points. We also completed 8 new tuck-in mergers with approximately $70 million of annualized revenues. While our proposed acquisition of certain Willis Towers Watson brokerage operations has terminated, our decades-long tuck-in merger program remains a proven strategic growth engine.

“Global P/C rates remain firm overall, and the increases we saw during the second quarter of 2021 were similar to the first quarter. At the same time, we are seeing increased economic activity across our client base. Customers are adding coverages and exposures to their existing policies, which is an encouraging sign for the underlying financial health of our clients. So as clients and prospects pivot away from controlling costs to growing their businesses and attracting, motivating and retaining their workforce, I believe our talented production staff is well positioned to help our clients navigate the current environment.

“2021 is shaping up to be a fantastic year!”

Termination of Agreement to Acquire Certain Willis Towers Watson plc Brokerage Operations

As we previously disclosed on July 26, 2021, our May 12, 2021 agreement to acquire certain Willis Towers Watson plc brokerage operations was terminated as a result of Aon plc and Willis Towers Watson plc terminating their combination. In conjunction with the termination of this agreement, we exercised the special optional redemption feature of our $650 million tranche of 10-year senior notes issued on May 20, 2021. These notes will be redeemed on August 13, 2021.

$1.5 Billion Share Repurchase Program

Today we also announced our Board of Directors authorized the repurchase of up to $1.5 billion of common stock under a new share repurchase plan. This repurchase plan replaces our prior repurchase program, of which approximately $1.0 billion remained.

Repurchases of common stock may be effected from time to time through open market purchases, trading plans established in accordance with the U.S. Securities and Exchange Commission’s rules, accelerated stock repurchases, private transactions or other means, depending on satisfactory market conditions, applicable legal requirements and other factors. The repurchase plan has no expiration date and we are under no commitment or obligation to repurchase any particular amount of our common stock under the plan. At our discretion, we may suspend the repurchase plan at any time.

Impact of COVID-19 Pandemic Recovery

Relative to second quarter 2020, during the second quarter 2021:

• Nearly all of our Brokerage segment operations’ revenues benefited from our clients’ improving business conditions which increases insured exposure units (i.e., insured values, payrolls, employees, miles driven, gross receipts, etc.),

• Our Risk Management segment operations revenue benefited from our clients’ improving business conditions which increases new arising workers compensation claims,

• Our clean energy investments benefited from higher electricity production due to increased demand for electricity from improving business conditions.

If economic conditions continue to improve, we believe we may also see favorable revenue benefits in our Brokerage and Risk Management segments and clean energy investments in the third and fourth quarters of 2021 relative to the same quarters in 2020. However, if economic recovery slows, we could see the favorable revenue and investment returns soften from second quarter 2021 levels.

During the second, third and fourth quarters of 2020 and first quarter 2021, we realized significant expense savings (totaling approximately $60 million to $75 million per quarter relative to the prior year same quarters, adjusted for pro forma full-quarter costs related to acquisitions) as a result of reduced travel, entertainment and advertising expenses, reduced costs from lower employee medical plan utilization, a reduction in workforce, wage controls, and reduced use of external consultants. During second quarter 2021, relative to second quarter 2020, as we increased our business activities, we saw modest increases in travel and entertainment, full restoration of advertising and more normalized usage of our employee medical plan, resumption of annual support-layer wage increases, increased use of external consultants, and a slight increase in incentive compensation. These incremental costs totaled approximately $15 million in our Brokerage segment relative to second quarter 2020. We believe we will see incremental Brokerage segment costs again in third and fourth quarter 2021, relative to the same quarters in 2020, of approximately $20 million and $30 million, respectively. However, if the pace of economic recovery accelerates, we could see expense increases greater than the estimates provided above.

Income Taxes

Gallagher allocates the provision for income taxes to its Brokerage and Risk Management segments using the local country statutory rates. Gallagher’s consolidated effective tax rate for the quarters ended June 30, 2021 and 2020 was 9.2% and 5.8%, respectively, which was lower than the statutory rate due to the production of IRC Section 45 clean energy tax credits. In third quarter 2020, Gallagher increased its estimated U.K. effective income tax rate from 17.5% to 19%. In second quarter 2021, the U.K. government enacted tax legislation that increases the corporate income tax rate from 19% to 25% effective in 2023. Gallagher incurred additional income tax expense in the quarter to adjust certain deferred income tax liabilities to the higher income tax rate.

Cautionary Information

This press release contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. When used in this press release, the words “anticipates,” “believes,” “contemplates,” “see,” “should,” “could,” “will,” “estimates,” “expects,” “intends,” “plans” and variations thereof and similar expressions, are intended to identify forward-looking statements. Examples of forward-looking statements include, but are not limited to, statements regarding the redemption of our $650 million tranche of senior notes; the repurchase of shares under our newly authorized share repurchase program; changes in our expenses in the next several quarters; the impact of the COVID-19 pandemic recovery; anticipated future results or performance of any segment or the Company as a whole; the premium rate environment and the state of insurance markets; and the economic environment.

Gallagher’s actual results may differ materially from those contemplated by the forward-looking statements. Readers are therefore cautioned against relying on any of the forward-looking statements, which are neither statements of historical fact nor guarantees or assurances of future performance. Important factors that could cause actual results to differ materially from those in the forward-looking statements include changes in worldwide and national economic conditions, including the pace of economic recovery following COVID-19; our actual acquisition opportunities; or other factors like Brexit; trade wars or tariffs; political unrest in the U.S. or other countries around the world; changes in premium rates and in insurance markets generally; and changes in the insurance brokerage industry’s competitive landscape.

(9 of 15)

In particular, the global spread of COVID-19 has created significant volatility and uncertainty and economic disruption that may impact our forward-looking statements. The extent to which the pandemic impacts our business, operations and financial results will depend on numerous evolving factors, many of which are not within our control and that we may not be able to accurately predict, including: its duration and scope; the effectiveness of vaccines, how quickly vaccines are distributed and administered, and our employees’ and the general population’s willingness to receive them; governmental, business and individuals’ actions that have been and continue to be taken in response to the pandemic, including new laws that raise corporate tax rates; the impact of the pandemic on economic activity and actions taken in response; the effect on our clients and client demand for our services; our ability to sell and provide our services, including limitations on travel and difficulties of our clients and employees working from home and closure of their facilities; the ability of our clients to pay their insurance premiums which could impact our commission and fee revenues for our services; the nature and extent of possible claims that might impact the ability of underwriting enterprises to pay supplemental and contingent commissions; the decrease in new arising workers’ compensation and general liability claims; the long-term impact of closing our offices and our employees working from home; the impact of lost revenue on our employees’ variable and base compensation levels; the impact of reduced investments and postponements related to business modernization projects; the impact of furloughed or terminated employees; and the impact of reduced advertising and sponsorship investments.

Please refer to Gallagher’s filings with the SEC, including Item 1A, “Risk Factors,” of its Annual Report on Form 10-K for the fiscal year ended December 31, 2020, its subsequently filed Quarterly Reports on Form 10-Q and the prospectus filed on May 17, 2021 for a more detailed discussion of these and other factors that could impact its forward-looking statements. The COVID-19 pandemic currently amplifies, and in the future could continue to amplify, the risks, uncertainties and assumptions, reflected in such risk factors. Any forward-looking statement made by Gallagher in this press release speaks only as of the date on which it is made. Except as required by applicable law, Gallagher does not undertake to update the information included herein or the corresponding earnings release posted on Gallagher’s website.

Information Regarding Non-GAAP Measures

In addition to reporting financial results in accordance with GAAP, this press release provides information regarding EBITDAC, EBITDAC margin, adjusted EBITDAC, adjusted EBITDAC margin, diluted net earnings per share, as adjusted (adjusted EPS), adjusted revenue, adjusted compensation and operating expenses, adjusted compensation expense ratio, adjusted operating expense ratio and organic revenue. These measures are not in accordance with, or an alternative to, the GAAP information provided in this press release. Gallagher’s management believes that these presentations provide useful information to management, analysts and investors regarding financial and business trends relating to Gallagher’s results of operations and financial condition or because they provide investors with measures that our chief operating decision maker uses when reviewing the company’s performance. See further below for definitions and additional reasons each of these measures is useful to investors. Gallagher’s industry peers may provide similar supplemental non-GAAP information with respect to one or more of these measures, although they may not use the same or comparable terminology and may not make identical adjustments. The non-GAAP information provided by Gallagher should be used in addition to, but not as a substitute for, the GAAP information provided. As disclosed in its most recent Proxy Statement, Gallagher makes determinations regarding certain elements of executive officer incentive compensation, performance share awards and annual cash incentive awards, partly on the basis of measures related to adjusted EBITDAC.

Adjusted Non-GAAP presentation - Gallagher believes that the adjusted non-GAAP presentations of the current and prior period information presented in this earnings release provide stockholders and other interested persons with useful information regarding certain financial metrics of Gallagher that may assist such persons in analyzing Gallagher’s operating results as they develop a future earnings outlook for Gallagher. The after-tax amounts related to the adjustments were computed using the normalized effective tax rate for each respective period. See pages 14 and 15 for a reconciliation of the adjustments made to income taxes.

• Adjusted measures - Revenues (for the Brokerage segment), revenues before reimbursements (for the Risk Management segment), net earnings, compensation expense and operating expense, respectively, each adjusted to exclude the following, as applicable:

• Net gains on divestitures, which are primarily net proceeds received related to sales of books of business and other divestiture transactions, such as the disposal of a business through sale or closure.

• Acquisition integration costs, which include costs related to certain large acquisitions, outside the scope of the usual tuck-in strategy, not expected to occur on an ongoing basis in the future once Gallagher fully assimilates the applicable acquisition. These costs are typically associated with redundant workforce, extra lease space, duplicate services and external costs incurred to assimilate the acquisition with our IT related systems.

• Transaction-related costs associated with the due diligence related to its now terminated agreement to acquire certain assets of Willis Towers Watson plc.

• Workforce related charges, which primarily include severance costs (either accrued or paid) related to employee terminations and other costs associated with redundant workforce.

• Lease termination related charges, which primarily include costs related to terminations of real estate leases and abandonment of leased space.

(10 of 15)

• Acquisition related adjustments, which include change in estimated acquisition earnout payables adjustments, impairment charges and acquisition related compensation charges.

• The impact of foreign currency translation, as applicable. The amounts excluded with respect to foreign currency translation are calculated by applying current year foreign exchange rates to the same periods in the prior year.

• U.K.-related tax-rate change, which represents the impact in second quarter 2021 of one-time income tax expense associated with the change in the U.K. effective income tax rate from 19% to 25% that is effective in 2023.

• Adjusted ratios - Adjusted compensation expense and adjusted operating expense, respectively, each divided by adjusted revenues.

Non-GAAP Earnings Measures

• EBITDAC and EBITDAC margin - EBITDAC is net earnings before interest, income taxes, depreciation, amortization and the change in estimated acquisition earnout payables and EBITDAC margin is EBITDAC divided by total revenues (for the Brokerage segment) and revenues before reimbursements (for the Risk Management segment). These measures for the Brokerage and Risk Management segments provide a meaningful representation of Gallagher’s operating performance for the overall business and provide a meaningful way to measure its financial performance on an ongoing basis.

• Adjusted EBITDAC and Adjusted EBITDAC Margin - Adjusted EBITDAC is EBITDAC adjusted to exclude net gains on divestitures, acquisition integration costs, workforce related charges, lease termination related charges, acquisition related adjustments and the period-over-period impact of foreign currency translation, as applicable and Adjusted EBITDAC margin is Adjusted EBITDAC divided by total adjusted revenues (defined above). These measures for the Brokerage and Risk Management segments provide a meaningful representation of Gallagher’s operating performance, and are also presented to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.

• Adjusted EPS and Adjusted Net Earnings - Adjusted net earnings have been adjusted to exclude the after-tax impact of net gains on divestitures, acquisition integration costs, the impact of foreign currency translation, workforce related charges, lease termination related charges, acquisition related adjustments and effective income tax rate impact, as applicable. Adjusted EPS is Adjusted Net Earnings divided by diluted weighted average shares outstanding. This measure provides a meaningful representation of Gallagher’s operating performance (and as such should not be used as a measure of Gallagher’s liquidity), and for the overall business is also presented to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.

Organic Revenues (a non-GAAP measure) - For the Brokerage segment, organic change in base commission and fee revenues, supplemental revenues and contingent revenues exclude the first twelve months of such revenues generated from acquisitions and such revenues related to divested operations in each year presented. These revenues are excluded from organic revenues in order to help interested persons analyze the revenue growth associated with the operations that were a part of Gallagher in both the current and prior periods. In addition, organic change in base commission and fee revenues, supplemental revenues and contingent revenues excludes the period-over-period impact of foreign currency translation to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability. For the Risk Management segment, organic change in fee revenues excludes the first twelve months of fee revenues generated from acquisitions in each year presented. In addition, change in organic growth excludes the period-over-period impact of foreign currency translation to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.

These revenue items are excluded from organic revenues in order to determine a comparable, but non-GAAP, measurement of revenue growth that is associated with the revenue sources that are expected to continue in the current year and beyond. Gallagher has historically viewed organic revenue growth as an important indicator when assessing and evaluating the performance of its Brokerage and Risk Management segments. Gallagher also believes that using this non-GAAP measure allows readers of our financial statements to measure, analyze and compare the growth from its Brokerage and Risk Management segments in a meaningful and consistent manner.

Reconciliation of Non-GAAP Information Presented to GAAP Measures - This press release includes tabular reconciliations to the most comparable GAAP measures, as follows: for EBITDAC (on pages 12 and 13, for adjusted revenues, adjusted EBITDAC and adjusted diluted net earnings per share (on pages 1 and 2), for organic revenue measures (on pages 4 and 6, respectively, for the Brokerage and Risk Management segments), for adjusted compensation and operating expenses and adjusted EBITDAC margin (on pages 5, 6 and 7, respectively, for the Brokerage and Risk Management segments).
