ATO Atmos Energy Corp

Atmos Energy Corporation (NYSE: ATO) today announced that an order has been issued by the Railroad Commission of Texas (Commission) relating to the company�s Mid-Tex Division rate case, filed in May of 2006. The order includes the following: A determination that the acquisition of the Mid-Tex assets was in the public interest. A permanent weather normalization adjustment (WNA) mechanism which is based upon the most recent 10 years of weather experience. The WNA mechanism provides for a stabilization of customer utility bills in periods of warmer or colder-than-normal weather. An approved capital structure of 52 percent debt/48 percent equity. An authorized return on equity of 10 percent. An annual revenue increase of approximately $4.5 million, or 66 cents per month for the average residential customer, effective immediately. A refund to customers of approximately $2.3 million related to the Gas Reliability Infrastructure Program (GRIP) annual filings. �This decision represents an important milestone for our Mid-Tex Division, with the finding that the acquisition of Mid-Tex by Atmos was in the public interest, the authorization for a permanent WNA mechanism, as well as the comprehensive review of our annual GRIP filings,� said Robert W. Best, chairman, president and CEO of Atmos Energy. Best added: �We commend the Commission for seeking to balance the interests of the company and our customers in this case. We remain committed to working within the regulatory process to recover our actual expenses, earn our authorized rate of return, and to continue making investments in our delivery system in the state of Texas.� Due to the continued strong performance of the company�s complementary non-regulated marketing business, Atmos Energy is reaffirming its fiscal 2007 earnings guidance in the range of $1.90 to $2.00 per diluted share. However, the mark-to market impact on the marketing company�s physical storage inventory at September 30, 2007, could affect earnings per diluted share.
