MBRX · Moleculin Biotech, Inc. · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“As of June 30, 2026, the Company had an accumulated deficit of $226.5 million since inception and had not yet generated any revenues from operations. Additionally, management anticipates that its cash on hand of $7.3 million as of June 30, 2026, is not sufficient to fund its planned operations for a period of at least one year from when these condensed consolidated financial statements are issued. These factors raise substantial doubt regarding the Company's ability to continue as a going concern.”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.
