DTE Energy reports first quarter 2015 results

DETROIT - DTE Energy (NYSE:DTE) today reported first quarter 2015 earnings of$273 million, or $1.53 per diluted share, compared with $326 million, or $1.84 per diluted share in 2014.

Operating earnings for the first quarter 2015 were$294 million or $1.65 per diluted share, compared with 2014 operating earnings of $300 million, or $1.69 per diluted share. Operating earnings exclude non-recurring items, certain mark-to-market adjustments and discontinued operations. Reconciliations of reported earnings to operating earnings are included at the end of this news release.

“DTE Energy’s solid first quarter performance sets us squarely on the path to achieve our financial and operational goals for 2015,” said Gerard Anderson, DTE Energy chairman and CEO. Anderson added that while he is proud of the company’s year-to-date 2015 financial results, he is also pleased with other recent developments that are beneficial to DTE customers.

• DTE Gas reduced natural gas prices charged to customers by 17 percent in the first quarter. Savings from a combination of reduced natural gas costs and DTE’s purchasing strategy is passed along to customers. The new gas cost is 57 percent lower than the April 2008 cost.

• DTE Electric reduced electric rates by six percent early in 2015, following a similar six percent reduction in early 2014.

• DTE Gas was recognized as highest in customer satisfaction¹ in its peer group for both residential and business customer satisfaction².

• DTE Energy was recently recognized by the Gallup organization as a Gallup Great Workplace for the third consecutive year - an award given to a handful of companies worldwide for their extraordinary ability to create an engaged workplace culture.

“DTE Energy continues to make significant investments to improve the reliability of electric distribution systems and reduce restoration times following power outages. We remain fully committed to providing clean, reliable and affordable energy for our customers,” concluded Anderson.

Outlook for 2015

DTE Energy reiterated its 2015 operating earnings per share guidance of $4.48 to $4.72.

“We are starting 2015 with a good first quarter. Colder than normal weather was a significant driver of our first quarter financial results, even though the winter of 2015 was less extreme than the record-setting cold winter of 2014,” said Peter Oleksiak, DTE Energy senior vice president and CFO. “We will continue to focus on maintaining our strong earnings as the year progresses.”

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 presentation, DTE Energy provides guidance for future period operating earnings. It is likely that certain items that impact the company’s future period reported results will be excluded from operating results. A reconciliation to the comparable future period reported earnings 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. For comparative purposes, 2009 through 2012 operating earnings exclude the Unconventional Gas Production segment that was classified as a discontinued operation on 12/31/2012.
