One company in the researched set discloses a stake in Nucor-Yamato Steel Company (Limited Partnership), none of it sized by anyone who discloses it.

Nucor-Yamato Steel runs a scrap based structural steel mini mill at Blytheville, Arkansas, using two electric arc furnaces to melt mostly recycled scrap with a small share of pig iron and roll it into wide flange beams, H piling, sheet piling, standard I beams, channels and other structural shapes for construction, energy, transportation and automotive customers. The mill has capacity for more than 2.5 million tons a year, describes itself as the largest structural steel mill in the Western Hemisphere, and employs on the order of 750 to 800 people. It was formed in 1987 as a partnership between Nucor and the Japanese structural steel maker Yamato Kogyo, which contributed beam rolling technology, and the plant started up on a former cotton field the following year.

Nucor-Yamato Steel Company (Limited Partnership) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Nucor-Yamato Steel (company website) and Nucor-Yamato Steel Blytheville plant (Global Energy Monitor). The ownership figures below come from the holders' filings instead, and are sourced row by row.
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.
- Nucor Corporation. FY2025 10-K: Nucor owns a 51% interest in Nucor-Yamato Steel Company (Limited Partnership), a Blytheville, Arkansas beam producer, and the entity is fully consolidated in Nucor's financial statements with the remaining 49% shown as noncontrolling interest, not carried as a separate equity-method investment. No fair value or carrying value for Nucor's 51% interest alone is disclosed anywhere in the 10-K or the Q2 2026 10-Q searched, so value_usd is null rather than estimated. The identity of the minority (49%) partner was not found in the text of either filing searched. source
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 Nucor-Yamato Steel Company (Limited Partnership) where a holder stated one, and are missing where no holder did.
