DTE Energy reports third quarter 2013 results; tightens guidance range

DETROIT - DTE Energy (NYSE:DTE) today reported earnings for the nine months ended Sept. 30, 2013 of $537 million, or $3.07 per diluted share, versus $529 million, or $3.08 per diluted share, in 2012. Year-to-date operating earnings were $541million or $3.09 per diluted share, compared with $529 million or $3.08 per diluted share in 2012. Operating earnings exclude non-recurring items and discontinued operations. Reconciliations of reported earnings to operating earnings are at the end of this news release.

Reported earnings for third quarter 2013 were $198 million, or $1.13 per diluted share, compared with $227 million, or $1.31 per diluted share in 2012. Operating earnings were $198 million or $1.13 per diluted share, versus $226 million, or $1.30 per diluted share in 2012. A return to near-normal temperatures this quarter from the record-setting high temperatures in DTE Energy’s electric service territory last year was partially offset by strong underlying temperature normal sales growth. Additionally, lower earnings this year from the gas segment was more representative of typical historical third quarter performance.

Gerry Anderson, DTE Energy’s chairman, president and CEO, said that he was pleased with year to date results and that the company was on track to meet its earnings guidance for the year. The solid financial results for the first nine months of the year reflect the company’s ongoing commitment to improve operations and reduce structural costs.

“These actions provide us the platform that allows us to invest in electric and gas system reliability, and to take an environmental leadership position by increasing our investments in renewable energy and environmental quality,” Anderson said.

The company said that it is proud of the environmental progress to date which is the result of significant investments in emission controls at all of its facilities, with particularly large investments at the Monroe Power Plant. Key emissions have been drastically reduced by over 80 percent so far. By 2016, all of these emissions will have been reduced by more than 90 percent.

Anderson also said that he expects the company to be actively engaged in both the federal greenhouse gas regulatory arena and the Michigan energy policy arena to drive continued environmental progress. It will also be crucial to strike a balance between environmental outcomes, and the reliability and affordability needs of customers.

“Our energy production will evolve significantly over the next decade to include increased quantities of renewable energy and natural gas generation,” Anderson said. “We know that the decisions we make will impact the environmental and financial health of the communities we serve, and we will work to ensure that these decisions provide the best balance of cleaner, affordable and reliable energy for our customers.”

Outlook for 2013

DTE Energy tightened its 2013 operating earnings guidance range to $3.95 - $4.15 per diluted share from $3.90 to $4.20 per diluted share.

“We are confident in our ability to achieve our financial goals in 2013 and are tightening our 2013 operating earnings guidance range,” said David E. Meador, DTE Energy executive vice president and chief financial officer.

“While our continued efforts to control costs and improve our day-to-day operations are clearly paying off, we have not wavered on our commitment to be a force for growth and prosperity in the communities we serve.” Meador added. “Since we made our commitment to increase spending with Michigan-based businesses at the end of 2010, DTE has spent close to $2 billion, representing thousands of new and sustained jobs in the state.”

This earnings announcement, as well as a slide presentation and supplemental information, is available at www.dteenergy.com.

DTE Energy plans to conduct a conference call with the investment community hosted by Meador at 11 a.m. EDT Friday, Oct. 25, to discuss third quarter 2013 earnings results.

In this release, DTE Energy discusses 2013 operating earnings guidance. It is likely that certain items that impact the company's 2013 reported results will be excluded from operating results. Reconciliations to the comparable 2013 reported earnings guidance are not provided because it is not possible to provide a reliable forecast of specific line items.

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, 2008 through 2012 operating earnings exclude the Unconventional Gas Production segment that was classified as a discontinued operation on 12/31/2012.
