Item 12.  Disclosure of Results of Operations and Financial Condition

On January 28, 2004, Airgas, Inc. (the "Company") reported its earnings for
its third quarter and nine months ended December 31, 2003, as described in
the press release attached as Exhibit 99.1 and incorporated herein by

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 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.
