Looking at this filing, I need to identify the substantive disclosure content. The filing is a Form 10-Q cover page, table of contents, and glossary for CMS Energy Corporation / Consumers Energy Company for the period ended September 30, 2026. The substantive financial content (financial statements, MD&A) is referenced in the table of contents but not actually included in the extracted text provided. However, the cover page and glossary do contain substantive disclosure content about the registrants, their securities, share counts, and corporate structure. Let me assess: the cover page discloses share counts, securities listed, exchange listings, filer status, and the glossary defines key terms and entities. The total substantive content exceeds 150 words easily. Now I'll produce the article based on what the filing actually states.
