Airgas Reports Second Quarter EPS Growth of 27%;
Outlook Remains Positive

RADNOR, PA — October 26, 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 earnings for its second quarter ended September 30, 2005. Net earnings for the quarter grew 30% to $29.6 million, or $0.38 per diluted share, compared to $22.8 million, or $0.30 per diluted share, in the same period a year ago. The current quarter includes pre-tax charges from asset losses related to hurricanes Katrina and Rita of $2.8 million, or $0.02 per share. The prior year includes integration expenses of $0.02 per diluted share related to the BOC acquisition.

Second quarter sales increased 19% to $714 million reflecting continued same-store sales growth and acquisitions. Total same-store sales were up 10% compared to the same quarter a year ago, with gas and rent up 8% and hardgoods up 11%, reflecting strength across customer segments and a supportive pricing environment.

“We delivered another strong performance, earning $0.40 per diluted share excluding the hurricane impact,” said Airgas Chairman and Chief Executive Officer Peter McCausland. “We remained focused on our core strategy and managing product supply and pricing in a tight market impacted by extraordinary events. Excluding the charges noted above, operating margin expanded 40 basis points to 9.3%, reflecting solid execution across the board.”

“Same-store sales of hardgoods were buoyed by general industrial demand and strong sales after the hurricanes in the Gulf Coast region,” added McCausland. “Gas and rent sales maintained good momentum, driven by solid volumes and pricing. We continued to see great results in our strategic growth categories of medical, specialty and bulk gas as well as safety products.”

Adjusted debt decreased $24 million in the quarter. Free cash flow for the six months ended September 30, 2005 was $26 million compared to $2 million for the period ended September 30, 2004. The definition of free cash flow, a reconciliation to the Consolidated Statement of Cash Flows, the definition of adjusted debt, a reconciliation to the Balance Sheet and a reconciliation of operating margin are included herein.

McCausland continued, “We are enjoying good momentum across our business. We expect to continue growing earnings nicely, with $0.37 to $0.39 per share in our third quarter, and we are affirming our full year EPS range of $1.50 to $1.56. The full year range includes the $0.02 per share impact from the hurricanes and both ranges contemplate the tight supply environment and recently announced price increases.”

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 $209.6 million and $189.9 million at September 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 (previously June 2006) and expire in June 2009.
(c)	Selling, distribution and administrative expenses in the three and six months ended September 30, 2005 include an estimated loss related to hurricanes Katrina and Rita of $2.8 million ($1.75 million after tax), or $0.02 per diluted share. The loss estimate is comprised of property damage and an additional provision for uncollectible trade receivables associated with customers in the affected areas.
(d)	Business segment information for the Company’s Distribution and All Other Operations segments is shown below:

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:

	Six Months Ended			Six Months Ended
(Amounts in thousands)	September 30, 2005			September 30, 2004
Net cash provided by operating activities	$	138,093		$	100,375
Less net cash provided by operating activities of NWS (1)		(8,761	)		(10,342	)
Plus:
Management fees paid by NWS (1)		607			530
Operating lease buyouts		7,141			8,110
Proceeds from sale of PP&E		2,646			2,200
Less:
Cash provided by the securitization of trade receivables		(19,700	)		(37,400	)

Add back capital expenditures of NWS (1)		12,128			4,429
Free Cash Flow	$	26,273		$	2,260

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)	September 30, 2005			June 30, 2005			Change in Adjusted Debt
Debt	$	803,737		$	819,836		$	(16,099	)
Adjustments to Debt:
Securitization of trade receivables		209,600			214,600			(5,000	)
National Welders – non-recourse debt (1)		(49,408	)		(45,764	)		(3,644	)
Interest rate swap agreements		(3,126	)		(3,539	)		413
Adjusted Debt	$	960,803		$	985,133		$	(24,330	)

⁽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.
