Substantial doubt about the company's ability to continue as a going concern.
“These conditions raise substantial doubt about our ability to continue as a going concern for a period of time within one year from the date that the financial statements accompanying this Quarterly Report on Form 10-Q are issued.”View the 10-Q filed Aug 11, 2026
Every disclosed holder of PONO 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 PONO
13F quarter Jun 30, 2026No chart: the summed disclosures exceed shares outstanding, so they are not parts of one whole.
| Holder group | Shares | % Out |
|---|---|---|
| Institutional (13F) | 20,831,590 | 120.08% |
| Insiders (Forms 3, 4, 5) | 0 | 0.00% |
| 13D/G-only blocks | 4,939,221 | 28.47% |
| Remaining | 8,422,954 | -48.55% |
| Registered funds (N-PORT, not summed) | 419,777 | 2.42% |
Shares outstanding: 17,347,857, 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.
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.

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.
