Corporate Governance Analyst

Reported affiliate sales by a long‑term holder; routine notice of dispositions.

The Form 144 excerpt lists multiple specific dispositions by Harlan Robins, each with a trade date, share count, and sale proceeds. Examples include 10,000 shares on 01/06/2026 and 24,395 shares across two trades on 02/02/2026 (examples shown).

These entries are a regulatory disclosure of intended sales rather than a corporate action; cash‑flow treatment is linked to the selling person and not the issuer. Subsequent filings or broker reports would show execution details and aggregate impact.

Compensation & Equity Specialist

Restricted Stock Units noted; some sales appear to follow compensation vesting.

The excerpt records securities "Acquired as compensation -- Restricted Stock Units" with an acquisition date of 03/06/2023. Several later sales by the same holder are listed with explicit dates and proceeds, indicating disposition of previously granted equity.

Grant and sale dates are presented; the filing does not specify whether sales resulted from plan rules or tax withholding. Further filings may clarify whether any sales were to satisfy withholding or diversification.
