Insights

Securities Analyst

TL;DR: Insider plans to sell vested RSUs: 33,292 shares (~$581k) via Morgan Stanley the day after vesting.

The filing documents a routine disposition of equity compensation: restricted share units vested on 09/10/2025 and the holder intends to sell those 33,292 shares on 09/11/2025 through Morgan Stanley Smith Barney LLC on the NYSE. The notice includes aggregate market value and outstanding share count but does not state the seller's role or motivation. This is a straightforward Rule 144 notice that provides transparency about an insider sale but contains no operational or financial performance details.

Corporate Governance Expert

TL;DR: Disclosure meets Rule 144 format; transaction arose from compensation vesting and is being executed through a broker.

The form indicates compliance with disclosure requirements for an intended sale of equity compensation. The report confirms the securities were acquired as RSUs from the issuer and that the sale will be broker-assisted. The filing includes the required representation regarding absence of undisclosed material adverse information. It does not identify the filer relationship to the company, any trading plan, or additional context on timing beyond the dates provided.
