Insights

Securities Analyst

TL;DR: Routine insider sale from vested restricted stock; size appears small relative to a public company.

The filing documents a proposed sale of 462 shares derived from restricted stock vesting and a recent sale of 500 shares. Both transactions appear to be routine dispositions of compensation-related equity rather than an open-market disposition triggered by specific corporate events. The disclosed aggregate market values ($90,972.42 and $94,564.25) suggest these are modest in absolute terms for a publicly traded company, implying limited direct impact on capitalization or share supply.

Compliance & Governance Expert

TL;DR: Form 144 appears complete for Rule 144 notification; includes acquisition, payment, and recent sales information.

The form records required elements: acquisition date and manner (restricted stock vesting), nature of payment (compensation), broker details, intended sale date, and prior sales within three months. The signer’s certification about absence of undisclosed material adverse information is included. From a governance perspective, the filing follows standard disclosure practices for Rule 144 notifications and supports market transparency for insider-derived sales.
