Airgas Reports First Quarter EPS of $0.66

Sales down 12%, same-store sales down 17%
Effective expense reductions mitigate impact of sales decline; operating margin of 11.0%
Diluted EPS of $0.66, down 19%, consistent with Company guidance
Adjusted cash from operations* of $183 million up 31%, free cash flow* of $119 million up 106%
Second quarter diluted EPS guidance of $0.64 to $0.69; full-year $2.65 to $2.85

RADNOR, Pa.--(BUSINESS WIRE)--July 23, 2009--Airgas, Inc. (NYSE:ARG), the largest U.S. distributor of industrial, medical, and specialty gases, and welding, safety, and related products, today reported earnings of $0.66 per diluted share for its first quarter ended June 30, 2009, consistent with the Company’s guidance.

Quarterly EPS results represent a 19% decline from prior year earnings of $0.81 per diluted share. First quarter sales were $1.0 billion, a decline of 12% from the prior year. Total same-store sales declined 17%, with hardgoods down 27% and gas and rent down 10%. Acquisitions contributed 5% sales growth in the quarter.

“Sales were consistently at the low end of our expectations throughout the quarter, and demand continues to be weak across most customer segments,” said Airgas Chairman and Chief Executive Officer Peter McCausland. “Manufacturing has shown the deepest declines, analytical and utilities have shown some resilience, and our medical sales posted positive growth.”

Between December and March, as previously announced, the Company fully implemented $45 million of annual expense reductions, which were in addition to $10 million of expected annual savings in fiscal 2010 from ongoing efficiency initiatives. “We have reacted quickly and effectively,” McCausland continued, “reducing expenses to mitigate the impact of declining sales. As a result, we have experienced only a modest decline in operating margin, to 11.0% from 11.5% last quarter and 12.1% in the first quarter last year.”

In light of the continued weak business climate and few signs of near-term recovery, the Company has identified an additional $12 million of annual expense reductions that will be fully implemented by the end of the second quarter.

“In addition to our focus on cost management, we continue to enhance and expand our offerings and capabilities to best serve our customers,” continued McCausland. “I am pleased with our ability to win new business, such as the supply contract we recently announced with NIST, the National Institute of Standards and Technology, which is the standard-setting body for EPA protocol gases.”

Free cash flow* in the first quarter was $119 million compared to $58 million last year, driven by adjusted cash from operations* of $183 million, up from $140 million last year, and by a 21% reduction in capital expenditures to $67 million this year. Return on capital* was 11.8% compared to 13.3% in the prior year.

“We continue to generate strong free cash flow, which we used to reduce debt and increase our dividend this quarter,” added McCausland. “We remain cautious in our near-term outlook and focused on forward progress for the long run.”

The Company expects earnings per diluted share of $0.64 to $0.69 for the second quarter. For fiscal 2010, the Company is updating its expectations to $2.65 to $2.85 per diluted share. The previously announced range was $2.60 to $2.90.

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 Friday, July 24. The teleconference will be available by calling (877) 857-6149.

Notes:

(a)		The Company participates in a securitization agreement with three commercial banks to sell up to $345 million of qualified trade receivables. Cash used for the securitization resulted in increased borrowings under the Company’s revolving credit facilities. The amount of outstanding receivables sold under the agreement was $295 million and $311 million at June 30, 2009 and March 31, 2009, respectively. 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.

(b)		The Company maintains a senior credit facility with a syndicate of lenders. Approximately $319 million was available to the Company under this facility at June 30, 2009.

(c)		Certain reclassifications have been made to the prior period consolidated financial statements to conform to the current presentation. These reclassifications principally resulted in increasing cost of products sold (excluding depreciation) and reducing selling, distribution and administrative expenses. Additionally, some revenue was reclassified between Gas and Rent and Hardgoods. These reclassifications were the result of conforming the accounting policies of National Welders to the Company’s accounting policies and were not material. Consolidated net sales and net earnings for the prior period were not impacted by the reclassifications.

(d)		During the fourth quarter of fiscal 2009, the Company changed the operating practices and organization of its air separation production facilities and national specialty gas labs. The new operating practices and organization reflect the evolution of these businesses and their role to support the regional distribution companies. The regional distribution companies market to and manage the end customer relationships, coordinating and cross-selling the Company’s multiple product and service offerings in a closely coordinated and integrated manner. As a result of these changes, these businesses are now reflected in the Distribution business segment. Also as a result of an organizational realignment, Airgas National Welders is now part of the Distribution business segment. Segment information from fiscal 2009 has been restated to reflect these changes. Business segment information for the Company’s Distribution and All Other Operations business segments is shown below:

Reconciliations of Non-GAAP Financial Measures (Unaudited)

Return on Capital

Operating Income - Trailing Four Quarters	$	497,922		$	499,643

Five Quarter Average of Total Assets	$	4,320,704		$	3,880,112

Five Quarter Average Capital Employed	$	4,213,459		$	3,769,728

Return on Capital		11.8	%		13.3	%

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 and adjusted cash from operations provide 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 its 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 and adjusted cash from operations metrics may be different from free cash flow and adjusted cash from operations metrics provided by other companies.
