Insights

Securities Analyst

TL;DR: Routine insider sale notice of a small RSU block shortly after vesting, filed under Rule 144.

This Form 144 documents a proposed sale of 2,000 common shares valued at $453,000, representing roughly 0.0077% of the reported 26,000,000 shares outstanding. The shares were acquired as RSUs on 08/28/2025 and are to be sold via Stifel Nicolaus around 09/03/2025 using a net exercise settlement. The timing—receipt on 08/28/2025 and near-term sale—appears consistent with an insider liquidating a recently vested award rather than a broader distribution event. No prior sales in the past three months are reported.

Corporate Governance Expert

TL;DR: Disclosure meets Rule 144 requirements; information is limited and indicates routine post-vesting disposition.

There is no indication of a trading plan date or 10b5-1 reliance in the provided fields.
