Airgas Reports Third Quarter EPS of $0.76,
13% Growth over Prior Year

RADNOR, PA — January 28, 2009 — Airgas, Inc. (NYSE: ARG), the largest U.S. distributor of industrial, medical and specialty gases, and welding, safety and related products, today reported growth in sales, operating income and earnings, as well as strong free cash flow* for its third quarter ended December 31, 2008.

Quarterly net earnings grew to $62.9 million, or $0.76 per diluted share, compared to $56.8 million, or $0.67 per diluted share, in the prior year, representing a 13% increase in earnings per share. The prior year quarter included $0.01 per diluted share of integration expense primarily associated with the acquisition of Linde’s U.S. packaged gas business, and a one-time $0.01 per diluted share tax benefit related to a change in state tax law.

Third quarter sales increased 7% from the prior year to $1.1 billion. Acquisitions contributed 6% to the increase, and total same-store sales grew 1% in the quarter, with gas and rent up 6% and hardgoods down 5%.

“Our strategic products, which have favorable long-term growth profiles and represent about 40% of sales, posted 4% organic growth in the quarter,” said Airgas Chairman and Chief Executive Officer Peter McCausland. “The second half of the quarter was characterized by widespread slowing across most of our customer segments, with relative strength in the medical, analytical, and food and beverage segments.

“Our operating margins held up relatively well, demonstrating our ability to react quickly in a downturn,” McCausland added, referring to the Company’s 12.1% operating margin in the quarter. “We generated $59 million of free cash flow this quarter, marking our sixth straight quarter of free cash flow in excess of $50

Page 2 of 10

million. Looking forward, we are targeting curtailment of capital expenditures as we complete significant plant projects in the next two quarters.”

Return on capital* increased 40 basis points over the prior year to 13.5%. Year-to-date free cash flow* was $171 million, compared to $162 million in the prior year.

Assuming a modest decline from third quarter sales and the realization of expected benefits from its previously announced expense reduction efforts, the Company expects earnings per diluted share of $0.73 to $0.76 in the fourth quarter, a range similar to third quarter earnings. The Company expects full-year earnings per diluted share of $3.16 to $3.19 in fiscal 2009, representing 19% to 20% growth over fiscal 2008. Prevailing economic conditions offer limited visibility into future sales and earnings, which should be taken into consideration when evaluating the Company’s guidance.

The Company will conduct an earnings teleconference at 11:00 a.m. Eastern Time on Thursday, January 29. The teleconference will be available by calling (888) 218-8059.

Notes:

(a)	During the nine months ended December 31, 2008, the Company purchased twelve businesses, including nine associated with the distribution of packaged gases and related hardgood products, one associated with the rental of safety equipment, one associated with refrigerant gases and one international acquisition related to the rental of welding equipment. The twelve acquired businesses historically generated aggregate annual revenues of approximately $184 million. A total of $253 million was paid for the acquisitions and the settlement of holdback liabilities associated with prior acquisitions.
(b)	The Company participates in a securitization agreement with three commercial banks to sell up to $360 million of qualified trade receivables. Net proceeds from the securitization were used to reduce borrowings under the Company’s revolving credit facilities. The amount of outstanding receivables sold under the agreement was $360 million at both December 31, 2008 and March 31, 2008. The “Discount on securitization of trade receivables” in the accompanying Consolidated Statements of Earnings represents the difference between the proceeds from the sale of trade receivables and the carrying value of those receivables.
(c)	The Company maintains a $1.7 billion senior credit facility with a syndicate of lenders. Approximately $231 million was available to the Company under this facility on December 31, 2008.
(d)	On July 3, 2007, the preferred stockholders of the National Welders joint venture exchanged their preferred stock for common stock of Airgas (the “NWS Exchange Transaction”). The Company issued 2.471 million shares of Airgas common stock to the preferred stockholders in exchange for all 3.2 million preferred shares of National Welders. As part of the negotiated exchange, the Company issued an additional 144 thousand shares (included in the 2.471 million shares) of Airgas common stock to the preferred shareholders, which resulted in a one-time net after-tax charge of $2.5 million, or $0.03 per diluted share.
(e)	The tables below present the computation of basic and diluted earnings per share for the three and nine months ended December 31, 2008 and 2007:

(1)	Prior to the July 3, 2007 NWS Exchange Transaction (see (d) above), the preferred stockholders of National Welders had the option to exchange their 3.2 million preferred shares of National Welders either for cash at a price of $17.78 per share or for approximately 2.3 million shares of Airgas common stock. If Airgas common stock had a market value of $24.45 per share or greater, exchange of the preferred stock was assumed because it provided greater value to the preferred stockholders. Based on the assumed exchange of the preferred stock for Airgas common stock, the 2.3 million shares were included in the diluted shares outstanding.
	The National Welders preferred stockholders earned a 5% dividend, recognized as “Minority interest in earnings of consolidated affiliate” on the consolidated statement of earnings. Upon the exchange of the preferred stock for Airgas common stock, the dividend was no longer paid to the preferred stockholders, resulting in additional net earnings for Airgas. For the period in which the exchange was assumed, the 5% preferred stock dividend was added back to net earnings in the diluted earnings per share computation.
	For periods prior to the NWS Exchange Transaction, the earnings of National Welders for tax purposes were treated as a deemed dividend to Airgas, net of an 80% dividend exclusion. Upon the exchange of National Welders preferred stock for Airgas common stock, National Welders became a 100% owned subsidiary of Airgas. As a 100% owned subsidiary, the net earnings of National Welders are not subject to additional tax at the Airgas level. For the period in which the exchange was assumed, the additional tax was added back to net earnings in the diluted earnings per share computation.
	Upon the July 3, 2007 NWS Exchange Transaction, the issued shares of Airgas common stock were reflected as outstanding shares for the basic and diluted earnings per share computation for the three-month period ended December 31, 2007. The diluted earnings per share computation for the nine-month period ended December 31, 2007 includes the effect of the items described above, of which the exchange shares have been weighted to reflect the impact of the exchange transaction.

Reconciliation of Non-GAAP Financial Measure (Unaudited)

     Return on Capital:

     Reconciliation and computation of return on capital:

(Amount in thousands)	December 31, 2008			December 31, 2007
Operating Income — Trailing Four Quarters	$	541,422		$	438,055
Five Quarter Average of Total Assets	$	4,122,411		$	3,455,477

Five Quarter Average Capital Employed	$	4,023,049		$	3,342,268
Return on Capital		13.5	%		13.1	%

The Company believes this return on capital computation helps investors assess how effectively the Company uses the capital invested in its operations. Our management uses return on capital as one of the metrics for determining employee compensation. Non-GAAP numbers should be read in conjunction with GAAP financial measures, as non-GAAP metrics are merely a supplement to, and not a replacement for, GAAP financial measures. It should be noted as well that our return on capital computation information may be different from the return on capital computations provided by other companies.

The Company believes that free cash flow provides investors meaningful insight into the Company’s ability to generate cash from operations, which is available for servicing debt obligations and for the execution of our business strategy, including acquisitions, the prepayment of debt, or to support other investing and financing activities. Non-GAAP numbers should be read in conjunction with GAAP financial measures, as non-GAAP metrics are merely a supplement to, and not a replacement for, GAAP financial measures. It should be noted as well that our free cash flow metric may be different from free cash flow metrics provided by other companies.
