Every disclosed holder of EOSE 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 EOSE

13F quarter Sep 30, 2026, combined view: filers that have not filed yet carry their Jun 30, 2026 positions

No chart: the summed disclosures exceed shares outstanding, so they are not parts of one whole.

Holder group	Holders	Shares	% Out	Summed
Institutional (13F)	350	228,043,756	62.62%	Yes
Insiders (Forms 3, 4, 5)	16	7,614,204	2.09%	Yes
13D/G-only blocks	4	195,261,381	53.62%	Yes
Remaining	—	66,751,597	-18.33%	Negative
Registered funds (N-PORT, not summed)	168	62,406,501	17.14%	No

Shares outstanding: 364,167,744, the issuer's latest cover-page count restated onto today's split basis.

Remaining is negative: the summed disclosures exceed shares outstanding, as when filings are dated at different times or holders that do not disclose their links count the same shares. It is flagged, not clipped.

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.
