Airgas Reports Record First Quarter Earnings per Share of $0.38

RADNOR, PA – July 27, 2005 — Airgas, Inc., (NYSE: ARG), the largest U.S. distributor of industrial, medical and specialty gases, welding, safety and related products, today reported strong growth in sales, operating income and net earnings for its first quarter ended June 30, 2005. Net earnings for the quarter grew 34% to $29.6 million, or $0.38 per diluted share, compared to $22.1 million, or $0.29 per diluted share, in the same period a year ago.

First quarter sales increased 27% to $691 million reflecting continued same-store sales growth and acquisitions. Total same-store sales were up 12% compared to the same quarter a year ago, with gas and rent up 10% and hardgoods up 14%, reflecting pricing actions and strength across customer segments.

“We delivered another strong quarter, growing EPS by 31%, as we capitalized on good market conditions. We had exceptional results in our strategic growth categories of medical, specialty and bulk gas and safety products,” said Airgas Chairman and Chief Executive Officer Peter McCausland. “Our leading market position and solid execution are contributing to steady growth of sales and earnings.”

“Demand continued to be quite strong,” added McCausland. “Same-store sales of hardgoods led the way again in the quarter, with gas and rent sales reaching double-digit growth, driven by strong volumes and pricing. The pricing actions also helped improve our operating margin by 30 basis points to 9.2%.”

Adjusted debt increased $57 million in the quarter, as the Company completed four acquisitions with annual sales totaling nearly $100 million. Free cash flow for the quarter ended June 30, 2005 was $7 million compared to a negative $9 million in the quarter ended June 30, 2004. Low or negative free

cash flow is typical in the first quarter due to fiscal year-end related payments. The definition of free cash flow, a reconciliation to the Consolidated Statement of Cash Flows, the definition of adjusted debt and a reconciliation to the Balance Sheet are included herein.

McCausland continued, “We have the right strategic focus and are committed to disciplined growth. Our customer markets are strong, we are executing well, and our fiscal 2006 outlook remains robust. We expect to earn $0.37 to $0.39 per share in our second quarter, and we are increasing our full year EPS guidance to $1.50 to $1.56.”

Notes:
(a)	The Company participates in a securitization agreement with two commercial banks to sell up to $225 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 under the agreement was $214.6 million and $189.9 million at June 30, 2005 and March 31, 2005, respectively.
(b)	On June 6, 2005, the Company’s consolidated affiliate, National Welders, entered into an agreement with its preferred stockholders under which the preferred stockholders prepaid their $21 million note payable to National Welders. National Welders used the proceeds from the prepayment of the preferred stockholders’ note to pay-off its $21 million term loan, which had been collateralized by the preferred stockholders’ note. The preferred stockholders’ note payable to National Welders had been reflected as a reduction of “Minority interest in affiliate” in the consolidated financial statements of the Company. Consequently, the prepayment of the preferred stockholders’ note resulted in a $21 million increase to the Company’s “Minority interest in affiliate.” Additionally, the preferred stockholders and National Welders agreed to modify the dates between which the preferred stockholders have the option to redeem their preferred stock for cash or Airgas common stock to commence in June 2005 and expire in June 2009.

Reconciliation of Non-GAAP Financial Measures (Unaudited)

Free Cash Flow:

Reconciliation of net cash provided by operating activities per the Consolidated Statement of Cash Flows to Free Cash Flow:

	Quarter Ended			Quarter Ended
(Amounts in thousands)	June 30, 2005			June 30, 2004
Net cash provided by operating activities	$	76,499		$	28,528
Less net cash provided by operating activities of NWS (1)		(3,445	)		(5,249	)
Plus:
Management fees paid by NWS (1)		298			263
Operating lease buyouts		941			922
Proceeds from sale of PP&E		735			678
Less:
Cash provided by the securitization of trade receivables		(24,700	)		(8,900	)
Capital expenditures		(47,265	)		(26,634	)
Add back capital expenditures of NWS (1)		4,409			1,555
Free Cash Flow	$	7,472		$	(8,837	)

Free Cash Flow provides investors meaningful insight into the Company’s ability to generate cash from operations, which can be used at management’s discretion for acquisitions, the prepayment of debt or to support other investing and financing activities.

⁽¹⁾ National Welders Supply Co. (“NWS”) is a consolidated corporate joint venture meeting the definition of a variable interest entity and for which the Company is the primary beneficiary as described under FIN 46R. The liabilities of NWS are non-recourse to the Company. Likewise, the cash flows in excess of a management fee paid by NWS are not available to the Company. Accordingly, the cash flows of NWS have been excluded from the Company’s non-GAAP liquidity measures.

Adjusted Debt:

Reconciliation of the change in debt per the Balance Sheet to the increase in debt adjusted for the non-recourse debt of NWS, off-balance sheet financing and non-cash interest rate hedging (“adjusted debt”):

(Amounts in thousands)	June 30, 2005			March 31, 2005			Change in Adjusted Debt
Debt	$	819,836		$	808,583		$	11,253
Adjustments to Debt:
Securitization of trade receivables		214,600			189,900			24,700
National Welders – non-recourse debt (1)		(45,764	)		(66,019	)		20,255
Interest rate swap agreements		(3,539	)		(3,948	)		409
Adjusted Debt	$	985,133		$	928,516		$	56,617

⁽¹⁾ In calculating the Adjusted Debt measure, the debt of the NWS joint venture has been excluded because the debt is non-recourse to Airgas.

The Company uses Adjusted Debt to provide investors with a more meaningful measure of the change in the Company’s obligation to repay debt by adjusting for the non-recourse debt of NWS, non-cash interest rate hedging and funds received (or repaid) under the trade receivables securitization program.
