4 EXHIBIT 99.1 AIRGAS REPORTS SOFTNESS IN SALES AND EARNINGS RADNOR, PA, December 18, 1998 -- Airgas, Inc. (NYSE - ARG) announced today that sales have continued to soften in the fiscal third quarter (which ends December 31, 1998). Same-store sales in the October-November period were slightly below the prior year. Lower revenues, coupled with the high level of repositioning activity and expense, will likely result in after-tax cash flow (net earnings plus depreciation, amortization and deferred income taxes) of $.42 - $.47 per share compared with $.48 per share last year, and earnings from operations of $.07 - $.12 per share, compared to the $.17 per share reported in last year's third quarter. Completion of the previously announced divestiture of the calcium carbide and carbon products manufacturing operations, expected late in the quarter, would result in a gain of approximately $.19 per share. Chairman and Chief Executive Officer Peter McCausland said, "Unfortunately, several segments of the U.S. industrial economy which Airgas serves have slowed dramatically at the same time that we are experiencing a high level of expenses associated with our Repositioning program and computer conversions. We see weakness in important customer segments such as oil and gas exploration and production, agricultural and farm machinery, and forest and paper products. In response to the weakening in these segments, we are taking actions to reduce future investments in, and accelerate the benefits of, the Airgas Direct Industrial infrastructure-build. In addition, we are implementing a company-wide cost improvement program. We are restricting acquisitions to industrial gas distributors. We continue to divest non-core businesses. We are aggressively managing capital expenditures and have targeted working capital improvements." Airgas is committed to making near-term improvements in financial performance while not jeopardizing the longer term ability to better meet the changing customer needs driven by consolidation of customer segments and aggressive initiatives by customers in supply chain management. Airgas, with its national network and extended product and service offerings will be ready to meet future customer requirements. Airgas expects to report its fiscal third quarter results on January 28, 1999. Airgas, Inc. is the largest distributor of industrial, medical and specialty gases and related equipment in the United States. Its distributor network includes over 700 locations in 44 states.
