This is the company's own disclosure. A payment disclosed on a Form D is a disclosed use of proceeds, not a finding of wrongdoing.
Each marker is one filing. The larger marker is the filing this page is about.
Trailing twelve months. 771 filings in Biotechnology, totalled by week. The dot is this raise, $25M, on the same scale — one filing against the whole group's total, so it sits low by construction.
