Insights

Corporate Governance / Insider Trading

TL;DR: Insider notice for sale of 12,000 shares (~$780K) tied to an option originally granted in 2016.

The Form 144 documents a planned open-market sale of 12,000 common shares on 10/03/2025 with an aggregate market value of $780,000.00, and states the shares were associated with an option granted 01/04/2016. This indicates the sale arises from a long-held equity award rather than an immediate corporate financing event.
