Insights

Financial Analyst

TL;DR: Routine insider sale of vested restricted stock; small absolute share count, disclosed under Rule 144.

The filing documents a planned sale of 8,728 common shares acquired via restricted stock vesting and paid as compensation. The use of Rule 144 indicates the seller is complying with resale limitations for restricted or control securities. The aggregate market value reported is $2,604,697.04 and the sale is to occur through Fidelity Brokerage Services on or about 09/09/2025. No prior sales in the past three months are reported, which supports this being a discrete transaction rather than an ongoing liquidation.

Corporate Governance Expert

TL;DR: Disclosure aligns with compliance expectations; signer attests no undisclosed material information.

The notice includes the required representations, including the signature attesting absence of undisclosed material adverse information and details on acquisition (restricted stock vesting) and consideration (compensation). The filing identifies the executing broker and an approximate sale date, meeting Rule 144 disclosure norms. The document does not provide the identity or role of the selling person nor any trading plan date, so governance context about insider status or trading intent is not specified.
