JUNS · Jupiter Neurosciences, Inc. · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“Our management has concluded that our historical recurring losses from operations and negative cash flows from operations as well as our dependence on private equity and other financings raise substantial doubt about our ability to continue as a going concern and our auditor has included an explanatory paragraph relating to our ability to continue as a going concern in its audit report for the fiscal years ended December 31, 2025 and 2024.”View the 10-Q filed Aug 14, 2026

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.
