For release:  IMMEDIATELY

              AIRGAS REPORTS FOURTH QUARTER EPS OF $0.25

RADNOR, PA - May 7, 2003  -- Airgas, Inc., (NYSE: ARG) today reported
earnings for its fourth quarter and fiscal year ended March 31, 2003.
Net earnings for the quarter were $18.2 million, or $0.25 per diluted
share, compared to $8.7 million, or $0.12 per diluted share, in the same
period a year ago.  The prior-year fourth quarter included a charge
related to a litigation settlement of $8.5 million ($5.7 million after
tax) or $.08 per diluted share.

The reported net earnings before the cumulative effect of a change in
accounting principle for the year ended March 31, 2003 were $68.1
million, or $0.94 per diluted share, compared to $48.6 million, or $0.69
per diluted share for the prior year.  Net earnings per diluted share
were $0.94 for year ended  March 31, 2003 versus a loss of ($0.15) in
the prior year, which reflects a change in accounting for goodwill.
Fiscal 2003 earnings reflect a first quarter restructuring charge of
$2.7 million ($1.7 million after tax) or $.03 per diluted share related
to the integration of the Air Products acquisition.

"The weak industrial economy created a very tough sales environment in
fiscal 2003.  However, we remained focused on executing our strategic
initiatives, pursuing growth in niches like medical and specialty gas,
and integrating acquired assets," said Airgas Chairman and Chief
Executive Officer Peter McCausland.  "I am very proud of the drive and
determination displayed by all Airgas associates during the year."

While fourth quarter sales increased 6% to $443 million, total same-
store sales declined 1% compared to the same quarter a year ago,
reflecting continued weakness in manufacturing and other industrial
segments.  Same-store sales in the Distribution segment were down 2%,
reflecting a 4% decline in hardgoods while gas and rent was flat.  Same-
store sales for the Gas Operations segment increased 6%.


The Company continued to generate strong free cash flow during fiscal
2003, enabling it to reduce adjusted debt by $96 million.  In line with
the new guidance from the Securities and Exchange Commission on the use
of non-GAAP financial measures, the Company has revised the calculation
of its liquidity measure "Free Cash Flow", making this useful measure
more transparent and traceable to the Statement of Cash Flows.  The new
definition of Free Cash Flow and a reconciliation to the attached
Consolidated Statement of Cash Flows, as well as the definition of
adjusted debt and reconciliation to the balance sheet are attached.
Free Cash Flow for the year ended March 31, 2003 was $104 million versus
$133 million in the prior year.  The fiscal 2003 decline in free cash
flow reflects an investment in the new liquid CO2 plant in Hopewell, VA;
a cash disbursement related to a prior year litigation settlement; and
higher cash interest payments on the prior year's subordinated debt
issuance resulting from a long first coupon period.

McCausland continued, "The year ahead looks like it may not be an easy
one as we could face as many challenges as opportunities, but I believe
we are a strong organization with the ability to execute in any
environment.  We expect to continue growing our earnings and project to
earn between $1.05 and $1.12 per diluted share in fiscal 2004.  The low
end of the range reflects a continuation of the current environment and
the high end assumes improvement."

2003, beginning at 8:30 a.m. Eastern Time.  Access the teleconference by

Notes:

(a)  Selling, distribution, and administrative expenses for the three months
   and year ended March 31, 2002 reflect the settlement of litigation, net of
   previously established reserves, of $8.5 million ($5.7 million after-tax)
   related to litigation brought about by Praxair, Inc. against the Company in
   July 1996.

(b)  Special charges of $2.7 million ($1.7 million after-tax) for the year
   ended March 31, 2003 consist of a first quarter restructuring charge
   related to the integration of the business acquired from Air Products and
   costs related to the consolidation of certain of the Company's procurement
   functions.  The special charges include facility exit costs associated with
   the closure of certain Airgas facilities and severance for approximately
   130 employees.

   On February 28, 2002, the Company completed its acquisition of the
   majority of
   the U.S. packaged gas business of Air Products and Chemicals, Inc.

(c)  In connection with the adoption of SFAS 142, the year ended March 31,
   2002 includes a $59 million non-cash charge recorded as the cumulative
   effect of a change in accounting principle for the write-down of goodwill
   to its fair value.  The impaired goodwill was not deductible for taxes, and
   consequently, no tax benefit was recorded in relation to the charge.

(d)  The Company participates in a securitization agreement with two
   commercial banks to sell up to $175 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 $158.9 million and $134 million at
   March 31, 2003 and March 31, 2002, respectively.
