| Schedule of Income, Assets, and Liabilities from Discontinued Operations | At September 30, 2026, the assets and liabilities classified as held for sale consisted of the following:
Certain of the entities held for sale are not wholly owned by NorthStar Clean Energy and are VIEs. As the primary beneficiary of these entities, NorthStar Clean Energy consolidates these entities and the remaining ownership interest is presented as noncontrolling interest on CMS Energy’s consolidated balance sheet. The noncontrolling interest associated with these consolidated VIEs held for sale totaled $479 million at September 30, 2026, before the attribution of $102 million of the impairment loss to the noncontrolling interest. NorthStar Clean Energy is obligated under certain indemnities, with varying durations, that protect the noncontrolling interests against losses incurred as a result of breaches of representations and warranties under the associated membership agreements. At September 30, 2026, the maximum obligation associated with these indemnifications was $180 million, and no amount has been recorded. CMS Energy expects to complete the divestment within 12 months of the date the disposal groups were classified as held for sale, subject to negotiating contractual terms with third parties, regulatory approvals, and other customary closing conditions. Because the sales process remains ongoing and is subject to market conditions and transaction-specific factors, the losses recognized upon completion of the sales could differ from the impairment charges recorded for the three and nine months ended September 30, 2026. Presented in the following table are the expenses comprising NorthStar Clean Energy impairment, disposal, and exit costs on CMS Energy’s consolidated statements of income:
1Includes $102 million attributable to noncontrolling interests. 2Includes breakage fees associated with development and equipment purchase contracts. Breakage fees incurred were reported as other current liabilities on CMS Energy’s consolidated balance sheet at September 30, 2026. Additional contract termination costs associated with the divestment strategy are not expected to be significant. 3The aggregate cost of the retention incentive and severance program is estimated to be $10 million and is expected to be substantially completed by December 31, 2026. Retention and severance amounts incurred to date were reported as other current liabilities on CMS Energy’s consolidated balance sheet at September 30, 2026.
