Lennox International announces new $500 million share repurchase plan; to be completed by the end of third quarter 2008

DALLAS, July 25, 2007 — Lennox International Inc. (NYSE: LII) today announced its board of directors has approved a share repurchase plan for $500 million. Based on the closing price on July 24, 2007, a $500 million repurchase would represent over 20% of the company’s market capitalization.

“The board of directors and I are committed to improving shareholder returns through a balanced and disciplined approach to investing cash,” said Todd Bluedorn, LII CEO. “We are confident a leveraged share repurchase program is an effective way to enhance the capital structure of LII, while maintaining the flexibility to pay quarterly dividends and pursue strategic opportunities to grow the business.

“This authorization underscores the confidence the board and I have in Lennox International and our future growth prospects. It is our plan to fully execute the repurchase by the end of 3Q 2008.”

The new share repurchase plan announced today will replace the share repurchase plan approved by the board in September 2005.
