DTE Energy reports third quarter 2017 results, raises guidance

• Ranked second in overall customer satisfaction with electric and gas residential customers in the Midwest by J.D. Power

• Received FERC Certificate of Approval and Notice to Proceed for NEXUS Gas Transmission project

DETROIT - DTE Energy (NYSE:DTE) today reported third quarter 2017 earnings of $270 million, or $1.51 per diluted share, compared with $338 million or $1.88 per diluted share in 2016.

Operating earnings for the third quarter 2017 were $264 million, or $1.48 per diluted share, compared with 2016 operating earnings of $353 million, or $1.96 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.

“Our financial performance this year is strong, putting us in a position to raise our 2017 earnings guidance. We’re heading into the final quarter of the year positioned for another successful year,” said Gerry Anderson, DTE Energy Chairman and CEO.”

Anderson highlighted recent company accomplishments:

• DTE Energy sent 600 employees and contractors to Florida to help restore power following Hurricane Irma. Mutual assistance is a hallmark of the electric power industry, and hundreds of employees volunteered for this assignment.

• DTE Energy ranked second in overall customer satisfaction with electric and gas residential customers in the Midwest in J.D. Power’s 2017 study. DTE has improved its customer satisfaction score every year since 2012.

• DTE Energy filed a Certificate of Necessity with the Michigan Public Service Commission (MPSC) to build a natural gas-fired power plant. The nearly $1 billion project is scheduled to break ground in 2019, creating hundreds of Michigan jobs during construction. It is one of the many steps DTE is taking to provide clean, affordable and reliable power, and achieve its goal of reducing carbon emissions by 30 percent by the early 2020s, and more than 80 percent by 2050.

• The NEXUS Gas Transmission project received its Certificate of Approval and Notice to Proceed from the Federal Energy Regulatory Commission. A pipeline that will bring new natural gas supplies to Ohio and Michigan to enable the transition to new power sources, NEXUS recently received a Notice to Proceed with Construction, and is expected to be in operation late in the third quarter of 2018.

• DTE Energy is driving economic development in downtown Detroit by powering Little Caesars Arena -  the new home of the Detroit Red Wings and Detroit Pistons - and The District Detroit. DTE built a new substation, along with an underground electrical system, to power the multi-use facility and its high-tech entertainment features. DTE is also the provider of natural gas for the arena.

Outlook for 2017

DTE Energy increased its 2017 operating earnings per share guidance to $5.38 - $5.69 from $5.26 - $5.57.

“Strong earnings from our non-utility businesses allowed us to re-evaluate our guidance and make an upward revision,” said Peter Oleksiak, DTE Energy senior vice president and chief financial officer. “Given the company’s

strong year-to-date performance, we are confident in raising our operating earnings guidance midpoint by $0.12 from $5.42 to $5.54 per share.”

This earnings announcement and presentation slides are available at dteenergy.com/investors.

In this release, DTE Energy discusses 2017 operating earnings guidance. It is likely that certain items that impact the company's 2017 reported results will be excluded from operating results. Reconciliations to the comparable 2017 reported earnings guidance are not provided because it is not possible to provide a reliable forecast of specific line items (i.e. future non-recurring items, certain mark-to-market adjustments and discontinued operations). These items may fluctuate significantly from period to period and may have a significant impact on reported earnings.

Many factors impact forward-looking statements including, but not limited to, the following: impact of regulation by the EPA, the FERC, the MPSC, the NRC, and for DTE Energy, the CFTC, as well as other applicable governmental proceedings and regulations, including any associated impact on rate structures; the amount and timing of cost recovery allowed as a result of regulatory proceedings, related appeals, or new legislation, including legislative amendments and retail access programs; economic conditions and population changes in our geographic area resulting in changes in demand, customer conservation, and thefts of electricity and, for DTE Energy, natural gas; environmental issues, laws, regulations, and the increasing costs of remediation and compliance, including actual and potential new federal and state requirements; health, safety, financial, environmental, and regulatory risks associated with ownership and operation of nuclear facilities; changes in the cost and availability of coal and other raw materials, purchased power, and natural gas; volatility in the short-term natural gas storage markets impacting third-party storage revenues related to DTE Energy; impact of volatility of prices in the oil and gas markets on DTE Energy's gas storage and pipelines operations; impact of volatility in prices in the international steel markets on DTE Energy's power and industrial projects operations; volatility in commodity markets, deviations in weather, and related risks impacting the results of DTE Energy's energy trading operations; changes in the financial condition of DTE Energy's significant customers and strategic partners; the potential for losses on investments, including nuclear decommissioning and benefit plan assets and the related increases in future expense and contributions; access to capital markets and the results of other financing efforts which can be affected by credit agency ratings; instability in capital markets which could impact availability of short and long-term financing; the timing and extent of changes in interest rates; the level of borrowings; the potential for increased costs or delays in completion of significant capital projects; changes in, and application of, federal, state, and local tax laws and their interpretations, including the Internal Revenue Code, regulations, rulings, court proceedings, and audits; the effects of weather and other natural phenomena on operations and sales to customers, and purchases from suppliers; unplanned outages; the cost of

protecting assets against, or damage due to, cyber crime and terrorism; employee relations and the impact of collective bargaining agreements; the risk of a major safety incident at an electric distribution or generation facility and, for DTE Energy, a gas storage, transmission, or distribution facility; the availability, cost, coverage, and terms of insurance and stability of insurance providers; cost reduction efforts and the maximization of plant and distribution system performance; the effects of competition; changes in and application of accounting standards and financial reporting regulations; changes in federal or state laws and their interpretation with respect to regulation, energy policy, and other business issues; contract disputes, binding arbitration, litigation, and related appeals; implementation of new information systems; and the risks discussed in our public filings with the Securities and Exchange Commission. New factors emerge from time to time. We cannot predict what factors may arise or how such factors may cause results to differ materially from those contained in any forward-looking statement. Any forward-looking statements speak only as of the date on which such statements are made. We undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events.

Use of Operating Earnings Information – Operating earnings exclude non-recurring items, certain mark-to- market adjustments and discontinued operations. 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 (i.e. future non-recurring items, certain mark-to- market adjustments and discontinued operations). These items may fluctuate significantly from period to period and may have a significant impact on reported earnings. Reconciliation of reported to operating earnings (non-GAAP) 17
