The issuer has several share classes — market cap covers the whole company.
CMS Energy supplies electricity and gas to Michigan — a regulated utility with a long capital programme.
Profit is set by the rate base and the allowed return rather than by the volume of energy sold, so the capital plan replaces a revenue forecast here: retiring coal plants, building wind and solar, upgrading distribution networks and replacing gas mains are scheduled years ahead.
A distinct state problem is reliability: worn overhead lines leave tens of thousands of homes without power in storms, and the regulator links the allowed return to reliability metrics. Demand is supported by industry and new connections. Risks: commission decisions, borrowing costs and weather, which moves gas consumption in winter. The dividend is raised annually.
