Atmos Energy Corporation CEO to Speak at Citigroup Conference; Company Maintains Fiscal 2006 Earnings Estimate.

DALLAS -- Robert W. Best, chairman, president and chief executive officer of Atmos Energy Corporation (NYSE:ATO), will speak at the Citigroup First Annual Power, Gas and Utilities Conference on Thursday, March 2, 2006, at 12:15 p.m. EST.

As previously disclosed, Atmos Energy Corporation is projecting to earn in the range of $1.80 to $1.90 per diluted share for the 2006 fiscal year. Because the company's operations are seasonal, operating results for the three months ended December 31, 2005, are not indicative of the results to be expected for the 12 months ended September 30, 2006.

A live webcast of this panel discussion will be broadcast on Atmos Energy's Web site at www.atmosenergy.com. The discussion will be archived for 30 days.
