AZITRA INC (AZTR)
Institutional ownership reported to the SEC as of Q2 2026, across 13 quarters.
Institutions report 103,378,446 shares against 60,603,742 outstanding. Shares only - option lines are excluded, which is why this can be compared with the company at all. The count comes from the cover page of the company's own most recent report, so it is dated when that was filed rather than at quarter end. Over 100% because an adviser and a sub-adviser can both report the same shares, and both are counted.
Options share is the part of reported value carried in derivative lines rather than shares. A high figure means institutions are expressing a view on this security without owning much of it.
