CLRB Cellectar Biosciences, Inc.
Executive Summary
Cellectar Biosciences filed Amendment No. 1 to its S-1 registration statement to register up to 51,998,413 shares of common stock for resale by selling stockholders, including shares issued in a May 2026 private placement and shares issuable upon exercise of warrants. The company will not receive proceeds from the resale but could receive up to $108.2 million if all warrants are exercised for cash. The filing highlights the company's pre-revenue status, going concern risk, and need for additional capital to fund regulatory strategy for its lead candidate iopofosine I 131.
