DTE Energy Announces Preliminary 2007 Earnings; Schedules Year-End Conference Call


DETROIT, Feb. 15 /PRNewswire-FirstCall/ -- DTE Energy (NYSE: DTE) today announced that it expects full year 2007 operating earnings of at least $2.70 per share excluding synthetic fuel, exceeding its previous guidance of $2.50 to $2.65 per share, due to solid performance in the company's utility and non- utility businesses.

Specifically, the company expects Detroit Edison's 2007 operating earnings to exceed its prior guidance range of $300 million to $310 million due primarily to lower operation and maintenance expenses in the fourth quarter, as well as a slightly better-than-expected local economy.

In addition, DTE Energy expects operating earnings from its non-utility businesses to exceed prior guidance primarily due to strong Power & Industrial and Gas Midstream performance.

DTE Energy plans to announce its full year 2007 earnings after market close Thursday, Feb. 21. DTE Energy will conduct a conference call to discuss earnings results at 9 a.m. EST Friday, Feb. 22.
