U.S.-based holding company DTE Energy Co. and its utility subsidiaries, DTE Electric Co. and DTE Gas Co., (collectively, DTE), continue to maintain sizable nonutility businesses, weighing down the overall business risk profile. We view DTE's business risk profile as "excellent" and its financial risk profile as "significant." We are revising our rating on outlook on DTE to stable from positive. We are also affirming our ratings on DTE, including the 'BBB+' issuer credit rating. The stable outlook reflects our base-case scenario that DTE will maintain its "excellent" business risk profile over the long term by strategically deciding not to grow its energy trading business and our view that the company's regulatory risk will remain low.
