LEHIGH VALLEY, Pa. (September 23, 2008) – Based on current financial data, Air Products (NYSE:APD) today announced that it anticipates posting fiscal 2008 fourth quarter diluted earnings per share (EPS) from continuing operations in the range of $1.24 to $1.26. The company’s previous earnings expectations for the fourth quarter were in the range of $1.37 to $1.42.

This revised outlook for the quarter is primarily attributable to the following factors:

• A fire sustained at the company’s Ulsan, Korea nitrogen trifluoride (NF₃) production facility required the plant to be shut down and is expected to impact fourth quarter EPS by $0.05. Air Products has been able to continue supplying NF₃ to its customers. The company anticipates bringing the Ulsan plant back online beginning in January 2009.

• Hurricanes Gustav and Ike reduced short-term demand from U.S. Gulf Coast customers and drove temporary increases in operational costs. This is expected to affect fourth quarter EPS by $0.05.

• The continued strengthening of the dollar against the Euro and Pound Sterling is expected to negatively impact fourth quarter EPS by $0.03.

• The slowdown in both semiconductor foundry and liquid crystal display (LCD) manufacturing has lowered demand for electronic equipment and materials and is expected to impact fourth quarter EPS by $0.03.

• Further weakening of the manufacturing environment in Europe has slowed sales and is expected to reduce fourth quarter EPS by $0.03.

• The company expects to see a favorable tax rate due to lower taxable income, which is expected to favorably impact fourth quarter EPS by $0.03.

Commenting on the revised outlook, Chairman, President and Chief Executive Officer John McGlade said, “Despite the fire, the hurricanes and a challenging economic environment, our financial position remains strong. With our capital spending increasing, a strong backlog of projects, and growing needs for industrial gases in the energy markets, we are very confident in our future growth. We remain committed to achieving double-digit earnings growth while continuing to improve our margins and returns.”

Air Products today published current business information addressing the quarter-to-date period on its Web site at www.airproducts.com/Invest/financialnews/current.htm.

The company will provide fiscal 2008 fourth quarter financial results on Wednesday, October 22, 2008, before the stock market opens and will host a teleconference later that day at 10:00 a.m. Eastern Daylight Time (EDT).
