NUWE · Nuwellis, Inc. · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“These conditions, including continued operating losses, negative cash flows from operations, an accumulated deficit of $325.7 million, and the need for additional capital to fund ongoing operations and growth initiatives (including the integration of Rendiatech Ltd., and Israeli company ("Rendiatech") following the Company's acquisition), raise substantial doubt about the Company's ability to continue as a going concern for at least twelve months from the date these financial statements are issued. ... While management's plans, including recent financing activities, cost discipline initiatives, and contingency measures, are intended to address these conditions, such plans do not alleviate the substantial doubt.”View the 10-Q filed Aug 13, 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.
