DTE Energy announces third quarter 2007 earnings

     DETROIT — DTE Energy (NYSE:DTE) today reported third quarter 2007 earnings of $197 million, or $1.19 per diluted share, compared with reported earnings of $188 million, or $1.06 per diluted share in the third quarter of 2006.

     Operating earnings including synfuels for the third quarter 2007 were $181 million, or $1.09 per diluted share, compared with third quarter 2006 operating earnings of $255 million, or $1.44 per diluted share. Operating earnings exclude non-recurring items, certain timing-related items and discontinued operations. Operating earnings decreased primarily due to mark-to-market gains at Energy Trading during third quarter 2006 that were not expected to repeat and 2007 startup and transition costs for new enterprise business systems.

     Year-to-date operating earnings excluding synfuels were $317 million or $1.84 per diluted share, compared with $377 million or $2.12 per diluted share in 2006. Operating earnings in the first three quarters of 2007 decreased primarily due to impacts at Detroit Edison including the one-time enterprise business system startup costs, a temporary rate reduction which expires in April 2008, lower service area sales and higher storm restoration expenditures.

     DTE Energy also reported year-to-date cash flow from operations of approximately $792 million. Including synfuel production payments, adjusted cash from operations was approximately $1.04 billion. Additionally, the company repurchased 14.8 million shares since December 2006, representing approximately $727 million of the expected $900 million share repurchase program.

     “We are confident that we’ll meet our updated annual operating earnings per share guidance of $2.50 to $2.65 excluding synfuels,” said Anthony F. Earley Jr., DTE Energy chairman and CEO. “When you set aside the one-time items this year, the underlying business is performing well. In addition, the strong cash flow from our successful restructuring of our non-utility businesses and synfuels provides significant flexibility to fund near-term growth.”

     Reported earnings for the nine months ended Sept. 30, 2007, were $716 million or $4.15 per diluted share versus $291 million or $1.64 per diluted share in 2006. Reported earnings increased primarily due to the gain from the sale of the company’s Antrim Shale gas exploration and production business. Year-to-date operating earnings were $436 million or $2.53 per diluted share, compared with $426 million or $2.40 per diluted share in 2006. Reconciliations of reported earnings to operating earnings for both the quarter ended and nine months ended Sept. 30, 2007 and 2006, are at the end of this news release.

Third quarter 2007 operating earnings results, by segment:

     Electric Utility:Operating earnings for Detroit Edison were $0.69 per diluted share versus $0.82 in the third quarter of 2006. Drivers of the variance included the temporary rate reduction agreed to in August 2006 as part of the settlement of the show cause proceeding, enterprise business system startup and transition costs, and increased storm restoration costs in 2007. The temporary rate reduction is approximately $79 million annualized and expires April 13, 2008.

     Gas Utility:MichCon had a seasonal operating loss of $0.13 per diluted share versus a $0.05 loss in the third quarter of 2006. The quarter-over-quarter variance was driven by enterprise business system startup and transition costs and higher uncollectible expense.

     Coal and Gas Midstream:Operating earnings in this segment, which includes non-utility gas pipelines and storage as well as coal transportation and marketing, were $0.09 per diluted share versus $0.06 in the third quarter of 2006. The improvement was primarily driven by increased storage margins.

     Unconventional Gas Production:Operating earnings from unconventional gas operations were $0.01 per diluted share, equivalent to third quarter 2006 operating earnings, primarily due to increased production from the Barnett Shale offset by the earnings impact from the second quarter sale of the Antrim business.

     Power and Industrial Projects:Operating earnings from Power and Industrial Projects were $0.02 per diluted share, equivalent to third quarter 2006 operating earnings.

     Energy Trading:Energy Trading had operating earnings of $0.27 per diluted share versus $0.36 in the third quarter of 2006. The year-ago quarter included mark to market gains.

     Synthetic Fuel:Operating earnings from the Synthetic Fuel segment were $0.27 per diluted share compared with $0.28 in the third quarter of 2006. Earnings declined primarily due to higher reserves for potential refunds to partners resulting from tax credit phase outs in 2007 offset by increased production.

     Corporate and Other:The Corporate and Other segment had an operating loss of $0.13 per diluted share compared with a loss of $0.06 in the third quarter of 2006. Driving the performance were higher taxes and interest in 2007.

Outlook for 2007/2008

     On Nov. 2, DTE Energy announced it revised its 2007 operating earnings guidance excluding synfuels to $425 million to $450 million from $450 million to $485 million. The revision was driven primarily by lower-than-expected earnings at Detroit Edison due to enterprise business system startup and transition costs, higher storm restoration expense and a slight decline in electric sales.

     DTE Energy raised its 2007 earnings guidance for its Coal and Gas Midstream and its Power and Industrial Projects segments. Coal and Gas Midstream has benefited from higher gas storage revenue.

     Higher earnings from the Power and Industrial segment resulted from increased sales at several of its projects. The delay in closing the sale of a 50 percent interest in a portfolio of projects also contributed to higher earnings in this segment. The company expects the sale to close by year-end.

     DTE is maintaining its outlook for 2008 and targets an 11 percent return on equity for both Detroit Edison and MichCon next year.

     “With many of the one-time cost pressures behind us by year-end 2007, I remain confident in our plan to produce 5 percent to 6 percent annual utility earnings growth for the foreseeable future,” said David E. Meador, DTE Energy executive vice president and CFO. “The expiration of the temporary rate reduction in April 2008 and expected resolution of the electric rate case in third quarter 2008 will help Detroit Edison earn its authorized return on equity next year. In addition, MichCon’s recent regulatory agreement provides an innovative framework for the company to earn its authorized return over the next two years.”

Conference call and webcast information

     This earnings announcement, as well as a package of supplemental financial information, will be available on the company’s website at dteenergy.com/investors.

     Use of Adjusted Cash From Operations — DTE Energy management believes that adjusted cash from operations provides a more meaningful representation of the company’s cash from ongoing operations and uses adjusted cash from operations as a primary performance measurement for communication with analysts and investors. Internally, DTE Energy uses adjusted cash from operations to measure performance against budget and to report to the Board of Directors.

     In this release, DTE Energy discusses 2007 operating earnings guidance. It is likely that certain items that impact the company’s 2007 reported results will be excluded from operating results. A reconciliation to the comparable 2007 reported earnings guidance is not provided because it is not possible to provide a reliable forecast of specific line items. These items may fluctuate significantly from period to period and may have a significant impact on reported earnings.
