DTE Energy reports third quarter 2011 results; narrows 2011 earnings guidance

DETROIT — DTE Energy (NYSE:DTE) today reported third quarter 2011 earnings of $183 million, or $1.07 per diluted share, compared with $163 million, or $0.96 per diluted share, in the third quarter of 2010.

Operating earnings for the third quarter 2011 were $183 million, or $1.07 per diluted share, compared with third quarter 2010 operating earnings of $163 million, or $0.96 per diluted share. Operating earnings increased primarily due to improved results at Energy Trading and Corporate & Other, partially offset by lower earnings at Power & Industrial Projects, Detroit Edison and MichCon. Operating earnings exclude non-recurring items and discontinued operations. Reconciliations of reported earnings to operating earnings are at the end of this news release.

“DTE Energy delivered good results in the third quarter, and we are on track to achieve our 2011 goals,” said Gerard M. Anderson, DTE Energy chairman, president and CEO. “Our aspiration is to be the best operated energy company in North America and our employees take great pride in finding opportunities to control costs, strengthen operating performance, and improve our customers’ experiences with DTE Energy.”

Reported earnings for the first nine months ended September 30, 2011 were $561 million or $3.30 per diluted share versus $478 million or $2.84 per diluted share in 2010. Year-to-date operating earnings were $482 million or $2.83 per diluted share, compared with $458 million or $2.72 per diluted share in 2010.

Outlook for 2011

DTE Energy narrowed its 2011 operating earnings guidance to $3.50 to $3.70 per diluted share from $3.40 to $3.70 per diluted share.

“With our solid operational and financial performance through the first nine months of the year, we are able to confidently narrow our operating earnings guidance range for 2011,” said David E. Meador, DTE Energy executive vice president and chief financial officer. “Looking beyond 2011, we will continue to execute on our utility and non-utility growth strategies, and are committed to being a force for growth and prosperity in the communities we serve.”

Earlier this year, DTE Energy joined a number of prominent companies across the state to become part of the Pure Michigan Business Initiative, a public-private venture to help perpetuate the philosophy of “economic gardening” in Michigan. The company committed to increasing purchases of goods and services from Michigan-based companies by $750 million over the next five years. As an example of this commitment, Meador pointed to DTE Energy’s recent groundbreaking of the Gratiot County Wind Farm, which when operational will generate clean, renewable energy for more than 50,000 Michigan homes. This project, which is being constructed by a Livonia, Michigan-based company, will provide over 200 temporary and permanent jobs and yield long-term economic benefits to the community.

This earnings announcement, as well as a package of slides and supplemental information, is available at www.dteenergy.com.

Use of Operating Earnings Information — DTE Energy management believes that operating earnings provide a more meaningful representation of the company’s earnings from ongoing operations and uses operating earnings as the primary performance measurement for external communications with analysts and investors. Internally, DTE Energy uses operating earnings to measure performance against budget and to report to the Board of Directors.

In this release, DTE Energy discusses 2011 operating earnings guidance. It is likely that certain items that impact the company’s 2011 reported results will be excluded from operating results. Reconciliations to the comparable 2011 reported earnings guidance are 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.
