JSPR · Jasper Therapeutics, Inc. · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“Accordingly, based on the Company's current operating plan, and along with the Company's history of operating losses, and given the potential risk of having to repurchase the Non-Voting Convertible Preferred Stock if the Company is unable to obtain stockholder approval to convert it to Common Stock within 12 months, the Company's current cash and cash equivalents may not be sufficient to fund the Company's ongoing operations for a period of at least twelve months from the issuance date of these condensed consolidated financial statements. Accordingly, the Company has concluded that substantial doubt exists about its ability to continue as a going concern.”View the 10-Q filed Aug 14, 2026

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.
