NEWS RELEASE ARTHUR J. GALLAGHER & CO. ANNOUNCES FOURTH QUARTER AND FULL YEAR 2013 FINANCIAL RESULTS

ITASCA, IL, January 28, 2014 - Arthur J. Gallagher & Co. (NYSE: AJG) today reported its financial results for the quarter and year ended December 31, 2013. A printer-friendly format and supplemental quarterly data is available at www.ajg.com. For a

description of the non-GAAP measures used to report financial results in this earnings release, please see "Information Regarding

Non-GAAP Measures" beginning on page 7.

"We had an excellent quarter to finish an outstanding year, and we are well positioned for 2014," said J. Patrick Gallagher, Jr., Chairman, President and CEO. "In the fourth quarter, our combined Brokerage and Risk Management segments posted 18% growth in adjusted total revenues, 6.2% organic growth in commission and fee revenues, 22% growth in adjusted EBITDAC and adjusted EBITDAC margin improved by 71 basis points."

Our Brokerage segment had a terrific quarter. Adjusted total revenues were up 22%, base organic commission and fee revenues grew 5.8%, adjusted EBITDAC was up 28% and adjusted EBITDAC margin was up 110 basis points. For the year, adjusted total revenues were up 18%, base organic commission and fee revenues grew 5.6%, adjusted EBITDAC was up

23% and adjusted EBITDAC margin was up 110 basis points.

Our Risk Management segment had an excellent organic growth quarter of 7.3%, yet adjusted EBITDAC margin of 14.3% fell slightly short of our fourth quarter target of 15.8%, almost entirely due to adverse medical plan severity. For the year, adjusted total revenues were up 8%, organic fees grew 9.3%, adjusted EBITDAC was up 6%. Adjusted EBITDAC margin of

15.8% nearly matched our forecasted target of 16% for the year.

Our acquisition program finished strong and our integration efforts are on track. During the fourth quarter, the Brokerage segment completed another 13 acquisitions with annualized revenues of $193.5 million bringing the count for the year to 30 with annualized revenues of $369.9 million. The Risk Management segment also closed a claim portfolio transfer from an insurance company, and going forward we will be their preferred administrator for certain claims. This transaction should generate another $12 to $15 million of annualized revenues for this segment. We are extremely pleased to welcome all of our new merger partners and associates to the growing family of Gallagher professionals.

As a result of our acquisition program and subsequent centralization efforts, during the fourth quarter we took actions to consolidate our management ranks and related support staff, mostly in our international operations. As a result, pretax charges in the Brokerage and Risk Management segments totaled $6.6 million and $1.5 million, respectively and should generate annual workforce cost savings of $9.0 million and $2.3 million, respectively.

Our clean energy investments had an outstanding quarter, exceeding our forecast. For the year, they generated

$63.7 million of after tax earnings, which was nearly double that of 2012.

We are comfortable with the current rate environment. Stable rates with carriers quoting individual lines and covers based on rational and informed underwriting continues to bode well for us. In this rate environment, our professionals can create solutions based on our deep industry knowledge, access the right markets and demonstrate our high-quality service offering.

We are increasingly optimistic about the recovering economy in the US and in the UK. We are hearing our clients speak more of growth and opportunity than we have in years.

"Finally, I am thrilled with the dozens of awards and recognitions we are receiving for our impeccable culture, our high-quality service, and our excellence in leadership and talent development. All of these demonstrate that our unique culture is thriving and most importantly, we are delivering valuable solutions to our clients and prospects."

Debt, interest and banking - At December 31, 2013, Gallagher had $925.0 million of long-term borrowings and

$530.5 million of short-term borrowings under its line of credit facility. As previously announced, Gallagher has entered into a note purchase agreement for a private placement of $600 million of senior unsecured notes, which is expected to fund on February 27, 2014. Proceeds will be used primarily to pay down its line of credit facility.

At-the-market equity program - Gallagher previously announced on November 20, 2013, that it had established an at-the- market equity program under which it may sell up to $200 million of its common stock through Morgan Stanley & Co. LLC as sales agent. During the fourth quarter 2013, Gallagher sold 91,572 shares of its common stock under the program at a weighted average price of $47.41 per share, resulting in net proceeds to Gallagher, after sales commissions, of approximately $4.3 million.

(5 of 11)

Corporate Segment Fourth Quarter Highlights (continued) Clean energy investments - The following provides certain information related to Gallagher's investments in limited liability companies that own 34 clean coal production plants, which produce refined coal using proprietary technologies owned by Chem-Mod. We believe that the production and sale of refined coal at these plants qualifies to receive refined coal tax credits under IRC Section 45 through 2019 for the fourteen 2009 Era Plants and through 2021 for the twenty 2011 Era Plants. The underlying operations of those investments where Gallagher has a controlling ownership interest are consolidated.

* Reflects management's current best estimate of the ultimate future potential annual after-tax earnings based on production estimates from the host utilities. However, host utilities do not consistently utilize the refined fuel plants at ultimate production levels due to seasonal electricity demand, as well as many operational, regulatory and environmental compliance reasons.

Gallagher's investment in Chem-Mod generates royalty income from clean energy plants owned by those limited liability companies in which it invests as well as refined coal production plants owned by other unrelated parties. Based on current production estimates provided by licensees, Chem-Mod could generate for Gallagher approximately $3.6 million of net after- tax earnings per quarter.

All estimates set forth above regarding the potential future earnings impact of our clean energy investments are subject to significant risks. 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, 2012, for a more detailed discussion of these and other factors that could impact the information above.

Acquisition costs - Consists mostly of external professional fees and other due diligence costs related to acquisitions. In fourth quarter 2013, this line also includes a net $0.4 million after-tax fair value loss related to three foreign currency

derivative investment contracts Gallagher executed in third quarter in connection with the signing of the agreement to acquire The Giles Group of Companies. These contracts were designed to hedge a portion of the GBP denominated purchase price consideration of this acquisition.

Corporate - Consists of overhead allocations mostly related to corporate staff compensation. Income Taxes

Gallagher allocates the provision for income taxes to its Brokerage and Risk Management segments as if those segments were computing income tax provisions on a separate company basis. Gallagher historically has reported, and anticipates reporting for the foreseeable future, an effective tax rate of approximately 37% to 39% in both its Brokerage and Risk Management segments. Gallagher's consolidated effective tax rate for the years ended December 31, 2013 and 2012 was

2.2% and 20.5%, respectively. Gallagher's tax rate for year ended December 31, 2013 was lower than the statutory rate and was lower than 2012 due to the amount of IRC Section 45 tax credits earned in 2013 compared to 2012.

Webcast Conference Call

Gallagher will host a webcast conference call on Wednesday, January 29, 2014 at 9: 15 a.m. ET/8:15 a.m. CT. To listen to this call, please go to www.ajg.com. The call will be available for replay at such website for not less than 90 days.

1995. When used in this press release, the words "anticipates," "believes," "contemplates," "see," "should," "could," "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 (i) the

amount of, and potential uses for, investment returns generated by Gallagher's clean energy investments; (ii) our corporate

income tax rate; (iii) anticipated future results or performance of any segment or the Company as a whole (including recent new business wins in the Risk Management segment and the Giles acquisition); (iv) anticipated cost savings from workforce reductions; (v) the premium rate environment; (vi) the economic environment; and (vii) anticipated funding under a note purchase agreement.

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 the following:

Risks and uncertainties related to Gallagher's clean energy investments including uncertainties related to political and regulatory risks, including potential actions by Congress or challenges by the IRS eliminating or reducing the availability of tax credits under IRC Section 45 retroactively and/or going forward; the ability to maintain and find co-investors; the potential for divergent business objectives by co-investors and other stakeholders; plant operational risks, including supply-chain risks; utilities' future use of, or demand for, coal; the market price of coal; the costs of moving a clean coal plant; intellectual property risks; and environmental risks - all could impact (i) and (ii) above; and

Changes in worldwide and national economic conditions (including an economic downturn due to a U.S. government shutdown or default and uncertainty regarding the European debt crisis), changes in premium rates and in insurance markets generally and changes in the insurance brokerage industry's competitive landscape - all could impact (iii) - (vii) above.

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, 2012, for a more detailed discussion of these and other factors that could impact its forward- looking statements.

The after-tax amounts related to the adjustments were computed using the normalized effective tax rate for each respective period.

Adjusted revenues and expenses - Gallagher defines these measures as revenues, compensation expense and operating expense, respectively, each adjusted to exclude net gains realized from sales of books of business, acquisition integration costs, New Zealand earthquake claims administration, South Australia and claim portfolio transfer ramp up fees/costs, workforce related charges, lease termination related charges, acquisition related adjustments and the impact of foreign currency translation, as applicable. Integration costs include costs related to transactions not expected to

occur on an ongoing basis in the future once we fully assimilate 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.

Adjusted ratios - Adjusted compensation expense ratio and adjusted operating expense ratio are defined as adjusted compensation expense and adjusted operating expense, respectively, each divided by adjusted revenues.

(7 of 11)

Earnings Measures - Gallagher believes that each of EBITDAC, EBITDAC margin, adjusted EBITDAC, adjusted EBITDAC margin and diluted net earnings per share (as adjusted) for the Brokerage and Risk Management segments, as defined below, provides a meaningful representation of its operating performance. Gallagher considers EBITDAC and EBITDAC margin as a way to measure financial performance on an ongoing basis. Adjusted EBITDAC, adjusted EBITDAC margin and diluted net earnings per share (as adjusted) for the Brokerage and Risk Management segments are presented to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.

EBITDAC - Gallagher defines this measure as net earnings before interest, income taxes, depreciation, amortization and the change in estimated acquisition earnout payables.

EBITDAC margin - Gallagher defines this measure as EBITDAC divided by total revenues.

Adjusted EBITDAC - Gallagher defines this measure as EBITDAC adjusted to exclude net gains realized from sales of books of business, acquisition integration costs, workforce related charges, lease termination related charges, New Zealand earthquake claims administration costs, South Australia and claim portfolio transfer ramp up fees/costs, acquisition related adjustments and the period-over-period impact of foreign currency translation, as applicable.

Adjusted EBITDAC margin - Gallagher defines this measure as adjusted EBITDAC divided by total adjusted revenues

(defined above).

Diluted net earnings per share (as adjusted) for the Brokerage and Risk Management segments - Gallagher defines this measure as net earnings adjusted to exclude the after-tax impact of net gains realized from sales of books of business, acquisition integration costs, New Zealand earthquake claims administration, South Australia and claim portfolio transfer ramp up fees/costs, the impact of foreign currency translation, workforce related charges, lease termination related charges, acquisition related adjustments and effective income tax rate impact divided by diluted weighted average shares outstanding. The effective income tax rate impact represents the difference in income tax expense for tax amounts derived using the actual effective tax rate compared to tax amounts derived using a normalized effective tax rate.

Organic Revenues - For the Brokerage segment, organic change in base commission and fee revenues excludes the first twelve months of net commission and fee revenues generated from acquisitions accounted for as purchases and the net commission and fee revenues related to operations disposed of in each year presented. These commissions and fees 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 year. In addition, change in organic growth excludes the impact of supplemental commission and contingent commission revenues and the period-over-period impact of foreign currency translation. 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. For the Risk Management segment, organic change in fee revenues excludes the first twelve months of fee revenues generated from acquisitions accounted for as purchases and the fee revenues related to operations disposed of in each year presented. In addition, change in organic growth excludes the impact of South Australia ramp up fees, New Zealand earthquake claims administration and 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 or are due to the limited-time nature of these revenue sources.

These revenue items are excluded from organic revenues in order to determine a comparable 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 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 page 9), for adjusted revenues, adjusted EBITDAC and adjusted diluted net earnings per share (on page 2), for organic revenue measures (on pages 3

and 4, respectively, for the Brokerage and Risk Management segments), for adjusted compensation and operating expenses and adjusted EBITDAC margin (on pages 4 and 5, respectively, for the Brokerage and Risk Management segments). Reported compensation and operating expense ratios can be found in the supplemental quarterly data available at www.ajg.com.
