DTE Energy Company (“DTE Energy”) will meet with investors August 24, 2017. A copy of the slide presentation from the meetings is furnished as Exhibit 99.1 to this report and will be available on DTE Energy's website, www.dteenergy.com on August 23, 2017. In the meetings, DTE Energy reaffirms its 2017 operating earnings per share guidance of $5.26-$5.57 per share.

In its slide presentation and this filing, 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.

40 Reconciliation of reported to operating earnings (non-GAAP) 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. Operating earnings are presented both with and without Energy Trading. The term “Growth Segments” refers to DTE Energy without Energy Trading and represents the business segments that management expects to generate earnings growth going forward. 2016 Actual DTE Electric DTE Gas Gas Storage and Pipelines Power and Industrial Projects Corporate and Other Growth Segments Energy Trading DTE Energy R r d rnings 622$ 138$ 119$ 95$ (61)$ 913$ (45)$ 868$ Pl t cl sure - - - - - - - - Link - - 8 - 2 10 - 10 Certain mark-to-market transactions - - - - - - 70 70 Operating Earnings 622$ 138$ 127$ 95$ (59)$ 923$ 25$ 948$ Net Income (millions) 2016 A u l DTE Electric DTE Gas Gas Storage and Pipelines Power and Industrial Projects Corporate and Other Growth Segments Energy Trading DTE Energy Repor ed Earnings 3.47 0.77 0.66 0.53 (0.35) 5.08 (0. ) 4.83 Plant closure - - - - - - - - Link 0.05 0.01 0.06 0.06 Certain mark-to-market transactions - - - - - - 0.39 0.39 Operating Earnings 3.47$ 0.77$ 0.71$ 0.53$ (0.34)$ 5.14$ 0.14$ 5.28$ EPS After-tax items: After-tax items: * ** * Total tax impact of adjustments to reported earnings: $51m ** Total tax impact of adjustments to reported EPS: $0.29

41 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)
