CLIR · ClearSign Technologies Corp · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“There can be no assurance that we will be successful in achieving our long term plans, or that such plans, if consummated, will result in profitable operations or enable us to continue in the long term as a going concern.”View the 10-Q filed Aug 14, 2026
Every disclosed holder of CLIR 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.

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.
