Insights

Securities Analyst

TL;DR: Routine Rule 144 notice for a modest insider sale; immaterial versus total share count.

The Form 144 discloses an intended sale of 47,000 common shares (aggregate value $250,792) through Morgan Stanley Smith Barney on 09/16/2025. Shares were granted as performance shares by the issuer on 05/17/2024. Given the reported 306,828,335 shares outstanding, the position represents about 0.015% of outstanding stock, indicating the transaction is small in absolute and percentage terms and unlikely to materially affect liquidity or valuation.
