CMS Energy Announces Departure of Chief Accounting Officer

CMS Energy Corp. disclosed the departure of its principal accounting officer in an 8-K filed with the SEC on June 3, 2026.

The filing, submitted under Items 5.02, 7.01 and 9.01, identifies the officer change and furnishes related disclosures. Item 5.02 requires companies to report departures or elections of directors and certain officers, including principal accounting officers, within four business days.

The departure alters the company's internal financial reporting leadership. Prior to the filing, the named individual held responsibility for CMS Energy's accounting functions and SEC reporting compliance as principal accounting officer. The new state leaves that role vacant until a successor is elected or an interim officer is designated.

The filing does not specify an effective date beyond the June 3 disclosure or cite a cause for the departure.

Downstream, the company must identify a replacement or interim principal accounting officer and file any subsequent Form 8-K updating Item 5.02 once that occurs. Regulation FD Item 7.01 indicates the company furnished additional information, attached as Exhibit 99.1 per Item 9.01, which markets and regulators will review for any material nonpublic details.

Standard SEC rules require the company to maintain accurate books and records and internal controls under the Sarbanes-Oxley Act, obligations now assigned to an acting officer until the position is permanently filled. Rating agencies and debt investors routinely factor executive continuity into credit assessments for utility holding companies such as CMS Energy.

This marks the latest executive transition reported by the Jackson, Michigan-based utility parent, whose primary subsidiaries include Consumers Energy. The Form 8-K represents the official record of the change; no prior announcements on the matter appear in the company's recent SEC filings.
