Analysis · GTBP · Life Sciences
GT Biopharma amended its September 14 securities purchase agreement to increase the offering from $7.45M to $7.75M and add a new purchaser, Nicholas Nikolov. The Greenshoe option also grew from $30M to $31.2M. This is a material delta from the prior 8-K — more capital raised and a new investor brought in — but the terms remain the same convertible preferred structure with warrants. For a company with a ~$13M market cap and going-concern doubts, this incremental capital is meaningful for runway, though the dilution mechanics are unchanged.
