Private company
Who owns Great Lakes Slag US, LLC
One company in the researched set discloses a stake in Great Lakes Slag US, LLC, none of it sized by anyone who discloses it. Great Lakes Slag US, LLC is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.
What this is
A 50/50 United States slag processing joint venture in the Great Lakes region, recorded only in its owners' own filings: CRH lists it in the Exhibit 21.1 subsidiary schedule of its 10-K as 50% held with products and services given simply as slag, and Votorantim Cimentos listed the predecessor Great Lakes Slag Inc. as a 50% US joint operation in its SEC registration statement.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- CRH plc. United States. Products/services: Slag. Not consolidated: accounted for under the equity method. CRH's FY2025 10-K reports a single combined 'Equity method investments' balance of $737 million as of 31 Dec 2025 ($620 million at 31 Dec 2024, $649 million at 31 Dec 2023, per the Adjusted ROIC reconciliation in Item 7 MD&A) covering ALL of the entities in this exhibit table together. The filing does not disclose a per-investee carrying value, so value_usd is null here per the combined-balance rule; the combined figure is recorded in notes and unknowns, not assigned to this row. sourcesource 2
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Great Lakes Slag US, LLC where a holder stated one, and are missing where no holder did.
