CMS Energy Corporation

The full register, from 13F filings

The Register tab above is hand research: a dozen holders, each traced to the filing it came from. This asks the same question of the whole market for the quarter ended 31-mar-2026, where 786 managers reported a position. Broad where the research is deep, and shallow in the ways a 13F always is.

Built from 13F filings, which report US listed, long, US custodied positions only. A register from this source is a floor rather than a level: a holder's true position can be far larger, as BlackRock's ASML stake shows at 1.28m shares in a 13F against 26.3m in its 13G/A. Holdings held through derivatives, outside US custody, or below a manager's reporting obligation do not appear. Where a holder is marked as a family, its total sums several separate filing entities and describes something no single filing describes; the constituent entities and their share counts are listed so the total can be checked. That roll-up can legitimately exceed the family's own Schedule 13G, because a 13G is filed by one legal entity: Vanguard reports Alphabet through ten advisory entities, and The Vanguard Group Inc itself reported zero after its January 2026 disaggregation.

What a reader needs to know to read these numbers

• CMS Energy Corporation and its wholly owned subsidiary Consumers Energy Company file a COMBINED 10-Q/10-K. Every figure in this file (shares outstanding, balance sheet 'Investments' line, register) was taken specifically from the CMS Energy Corporation columns/cover-page entries, never the parallel Consumers Energy Company figures which appear alongside them on the same pages (e.g. the cover page separately states a Consumers Energy Company common share count under a different heading, and the Q2 2026 10-Q balance sheet section presents CMS Energy's consolidated figures, $40,905 million total assets, immediately followed by a separate Consumers Energy Company consolidated balance sheet, $38,266 million total assets; only the CMS Energy block was used).
• Holdings side: CMS Energy's NorthStar Clean Energy segment (via wholly owned subsidiary HYDRA-CO Enterprises, Inc.) holds a 50 percent equity-method interest in each of four non-consolidated VIE limited partnerships operating independent power plants: T.E.S. Filer City Station, Grayling Generating Station, Genesee Power Station, and Craven County Wood Energy, per the Q2 2026 10-Q's 'Non-consolidated VIEs' disclosure and confirmed by the FY2025 10-K Exhibit 21 subsidiary list's parenthetical ownership percentages for each partnership chain. None of the four is individually sized in dollars anywhere searched: the 10-Q's equity-method table lists only Name/Nature/Involvement with no dollar column, and CMS Energy's consolidated balance sheet carries a single combined 'Investments' line within Total other non-current assets ($63 million at 30 Jun 2026, $61 million at 31 Dec 2025) that is not broken out by investee. Per the project's combined-balance rule, all four holdings are recorded with shares and value_usd null; pct_of_target (50%) is sourced separately per investee from Exhibit 21 and is not affected by the combined-balance issue.
• Also searched the Q2 2026 10-Q and the FY2025 10-K Exhibit 21 for 'unconsolidated', 'joint venture', and 'non-marketable': zero hits for all three terms in the 10-Q (the filing instead uses 'partnerships' and 'variable interest entities'); Exhibit 21 is otherwise a subsidiary ownership-percentage list as described above, with no additional named minority equity stakes beyond the four VIE partnerships found.
• Register: 9 rows, share total 128,551,682, self-gate 128,551,682 / 313,577,136 = 41.00% of CMS Energy Corporation shares outstanding (13 Jul 2026 cover page denominator). No row carries is_aggregate=true with member rows rolling into it (the insider row is a single proxy-stated group total with no individually listed member rows in this register), so the self-gate reduces to a plain sum of all 9 rows.
• Vanguard case: parent CIK 0000102909 filed Form 13F-NT (notice, no holdings) for Q2 2026, so per the project's rule the 8 successor entities ARE the position. Swept all 8 (7 hold CMS, 1 holds zero); summed the 7 that hold, per the method_note on that row.
• Every institutional register row's implied price per share (value_usd / shares) clusters between $76.21 and $77.93 as of 30 Jun 2026, cross-validating the family sums and the T. Rowe Price / Cohen & Steers thousands-to-dollars conversions.
• The DEF 14A (filed 26 Mar 2026) separately discloses, from older Schedule 13G/A filings, stale figures for reconciliation: The Vanguard Group 37,037,011 sh / 12.0% (13G/A filed 13 Feb 2024), BlackRock, Inc. 26,393,497 sh / 8.5% (13G/A filed 17 Apr 2025), JP Morgan Chase & Co. 18,441,853 sh (13G/A filed 24 Oct 2025). Per the project's rule to prefer the fresh Q2 2026 13F over a stale 13G quoted in a proxy, these are superseded by the fresh figures above and recorded here only for reconciliation.
• Capital Group family sweep checked 5 registrants (Capital Research Global Investors, Capital World Investors, Capital International Investors, Capital International Inc./CA, Capital International Sarl); 3 hold zero CMS shares as of Q2 2026 and are excluded from the row rather than included at null.
• The project's own data/registers/CMS.json snapshot (period 31 Mar 2026) additionally lists large positions for MFS (Massachusetts Financial Services), Victory Capital, Wellington Management, DZ Bank AG, and Deutsche Bank AG among others; these were not individually re-verified against fresh Q2 2026 13F-HR filings within this chunk's time budget and are omitted from the register rather than carried forward stale. This is a scope choice, not a finding that they no longer hold CMS.
