Airgas Announces Pricing Actions Effective August 1, 2008

Business Wire, June 30, 2008

RADNOR, Pa. -- Airgas, Inc. (NYSE:ARG) today announced that beginning August 1, 2008, or as contracts permit, its operating units will increase prices on gases and equipment. Prices will increase, on average, as follows:

* 20% for bulk and cylinder acetylene, argon, and hydrogen

* 15% for bulk and cylinder oxygen, nitrogen, carbon dioxide, helium, and specialty gases

* 15% for cylinder and bulk equipment rental fees

Prices will also increase for hardgoods and safety supplies, and delivery and other service charges.

These actions are being implemented in response to increases in product costs from suppliers and rising operating costs at Airgas plants and distribution facilities, driven by higher raw material, energy, electricity, and labor costs. Rising metal prices are also driving up costs for cylinders, bulk tanks, gas handling plants, and equipment.

"Costs continue to escalate rapidly, while strong demand is sustained across our customer base," said Airgas Chairman and Chief Executive Officer Peter McCausland. "Airgas associates are working hard every day to enhance our supply chain and meet our customers' needs. We will continue to invest in our infrastructure so we can meet the demands of our customers, improve operating efficiencies, and fulfill the safety and security requirements of our industry."
