Every disclosed holder of SCWO in one list: 13F institutions, Schedule 13D and 13G filers, insiders (Forms 3, 4 and 5) and registered funds, each from its own latest filing. Holders nest by CIK and SEC reporting links, never by name, and each is summed once.

Who Owns SCWO

13F quarter Sep 30, 2026, combined view: filers that have not filed yet carry their Jun 30, 2026 positions
Holder group Shares % Out
Institutional (13F) 1,856,964 10.48%
Insiders (Forms 3, 4, 5) 0 0.00%

Remaining 13,886,434 78.37%
Registered funds (N-PORT, not summed) 449,720 2.54%

Shares outstanding: 17,718,161, the issuer's latest cover-page count restated onto today's split basis.

Insiders are listed but not summed: the issuer has more than one class of common stock and Forms 3, 4 and 5 report one issuer-wide balance across them.

13D/G-only counts each filer's latest 13D or 13G that no 13F report of the listing contains, that names no 13F filer and that no counted insider files. Funds are never summed: their shares sit inside their advisers' 13F reports.

Shares are restated onto today's split basis. Change compares each row with the same holder's previous filing in the same source; a dash means there is none to compare. Nested 13D/G, insider and fund rows are not summed, since a 13F report already holds them.
