Insights

Securities Analyst

TL;DR: Insider plans to sell 42,237 shares (0.022% of outstanding) via Morgan Stanley on 08/21/2025; recent insider sales totaled 17,353 shares for $871,722.75.

The filing is a routine Form 144 disclosure showing an intended sale of restricted stock by an affiliate/insider. The size of the proposed sale (42,237 shares, aggregate market value $2.09M) is small relative to the reported outstanding shares (191.17M), suggesting limited direct dilution or market impact solely from this transaction. Recent sales by the same name on 08/18/2025 totaling 17,353 shares and $871,722.75 in proceeds are documented and should be considered when assessing insider disposition activity.

Compliance/Risk Analyst

TL;DR: Form 144 properly lists acquisition dates, restricted stock nature, broker, and recent sales; signer certifies absence of undisclosed material adverse information.

The disclosure includes required details: broker name, exact share counts, acquisition dates and nature (restricted stock), and recent sales by the filer. The filing contains the standard attestation regarding material adverse information and warns against intentional misstatements. No regulatory exceptions or missing mandatory fields are evident within the provided content.
