Item 12.  Disclosure of Results of Operations and Financial Condition

On October 29, 2003, Airgas, Inc. (the "Company") reported its
earnings for its second quarter and six months ended September 30,
2003, 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 non-cash items 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.
