DTE Energy announces 2007 Results: $5.70 Per Share of Reported Earnings, $2.82 Per Share of Operating Earnings

Non-utility asset sales drive reported earnings increase
PRNewswire-FirstCall
DETROIT
(NYSE:DTE)

DETROIT, Feb. 21 /PRNewswire-FirstCall/ -- DTE Energy (NYSE: DTE) today announced reported 2007 earnings of $971 million, or $5.70 per diluted share, compared with $433 million, or $2.43 in 2006. The earnings growth was largely due to the sale of the company's Antrim Shale business and an increase in synthetic fuel income.

"We are pleased with our reported earnings because it reflects the success of our non-utility monetization plan," said Anthony F. Earley Jr., DTE Energy Chairman and CEO. "We recognize, however, that the long-term growth of our utilities, Detroit Edison and MichCon, is the key to our future success. Our core utility businesses are now positioned to deliver strong, sustained earnings.

"We expect more than 80 percent of our earnings to come from our utilities in 2008 and beyond as we make investments in our utilities to produce clean, reliable and cost-effective energy for our customers. In 2008 we look forward to collaborating with key stakeholders to enact comprehensive energy legislation that will secure Michigan's energy future."

2007 operating earnings excluding synthetic fuel were $2.82 per diluted share compared with $2.89 in 2006. Earnings increased at the company's MichCon gas utility business primarily due to colder weather, while Power & Industrial Projects showed strong earnings growth primarily due to benefits from project restructuring actions taken in 2006. The repurchase of approximately 13.8 million shares of common stock during 2007 also drove earnings per share higher. These increases were offset by the temporary rate reduction at Detroit Edison and lower earnings at Energy Trading primarily due to the absence of strong earnings recorded in 2006. Reconciliations of reported to operating earnings for both the quarter ended and 12 months ended Dec. 31, 2007 and 2006, are at the end of this news release.

Operating earnings and other results for 2007, by segment:

Electric Utility: Operating earnings for Detroit Edison were $2 per diluted share versus $2.03 in 2006. Drivers of the variance included the temporary rate reduction, which expires in April 2008, computer system start- up costs and higher storm-restoration expense, partially offset by the return of customers from Electric Choice, warmer summer weather and the reconciliation of power supply costs from 2004 and 2005.

Gas Utility: Primarily consisting of MichCon, this segment had operating earnings of $0.48 per diluted share compared with $0.36 in 2006. Driving the improvement was favorable weather partially offset by computer system start-up costs.

Coal and Gas Midstream: This segment had operating earnings of $0.31 per diluted share compared with $0.29 in 2006. Higher gas storage revenues were the primary driver for the increase in earnings.

Unconventional Gas Production: Operating earnings for this segment were $0.06 per diluted share compared with $0.05 in 2006, primarily due to higher gas production from the Barnett Shale offset by the impact from the June 2007 sale of the company's Antrim Shale business.

Power and Industrial Projects: Operating earnings from Power and Industrial Projects were $0.15 per diluted share compared with an operating loss of $0.04 per diluted share in 2006. Key earnings drivers were increased coke production in 2007 and improved performance from projects restructured in 2006.

Energy Trading: This segment had operating earnings of $0.31 per diluted share compared with $0.54 in 2006. Timing-related gains in 2006 were not repeated in 2007.

Corporate and Other: This segment had an operating loss of $0.49 per diluted share, compared with a loss of $0.34 in 2006, primarily due to higher single-business tax and interest in 2007.

Synthetic Fuel: As planned, the company classified the synthetic fuel business as a discontinued operation as of Dec. 31, 2007, due to the expiration of production (or Section 29) tax credits. Therefore, synthetic fuel earnings are excluded from operating earnings. This segment had GAAP reported earnings of $1.20 per diluted share versus $0.27 in 2006. This favorable variance was driven by increased production.

Outlook for 2008

DTE Energy reiterated its 2008 operating earnings guidance of $2.70 to $3.10 per diluted share.

"In 2008, we remain committed to earning our authorized returns at Detroit Edison and MichCon," said David E. Meador, DTE Energy executive vice president and chief financial officer. "We delivered $100 million in incremental cost reductions in 2007 and expect that our current continuous improvement initiatives will enable us to provide best-in-class operational efficiency and customer service while producing long-term earnings growth."
