Disclosure of Results of Operations and Financial Condition ___________________________________________________________ On May 5, 2004, Airgas, Inc. (the "Company") reported its earnings for its fourth quarter and fiscal year ended March 31, 2004, as described in the press release attached as Exhibit 99.1 and incorporated herein by reference. The information contained in this Form 8-K report shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934 or incorporated by reference in any filing under the Securities Exchange Act of 1933, as amended, except as expressly set forth by specific reference in such a filing. Non-GAAP Measures: _________________ The press release attached as Exhibit 99.1 contains certain financial measures that are not defined under generally accepted accounting principles (GAAP). Free Cash Flow is a non-GAAP measure that provides investors meaningful insight into the Company's ability to generate cash from continuing operations, which can be used at management's discretion for acquisitions, the repayment of debt or to support other investing and financing activities. The Company uses the non-GAAP measure Adjusted Debt to provide investors with a more accurate and meaningful measure of the change in the Company's obligation to repay debt by adjusting for the non-recourse debt of the National Welders joint venture, non-cash interest rate hedging and funds received or repaid under the trade receivables securitization program. The Company's intent is to provide non-GAAP financial information to enhance investors' understanding of the Company's consolidated financial statements and should be considered by the reader in addition to, but not instead of, the financial statements prepared in accordance with GAAP.
