Insights

Corporate Insider & Compensation Analyst

Routine vesting and plan-based sales reduced holdings by 2,627 shares.

The first sale of 1,351 shares on 10/02/2025 was an automatic transfer to cover withholding from vested restricted stock units, a common compensation tax event. The second sale of 1,276 shares on 10/03/2025 was executed under an existing Rule 10b5-1 plan adopted on 02/25/2025.

These actions lower reported direct holdings to 282,924 shares and are consistent with normal executive compensation mechanics; monitor future filings for further plan-based activity over the next 6–12 months.

Securities Compliance Counsel

Transactions follow documented compliance procedures (withholding sale and 10b5-1 plan).

The filing explicitly states the withholding sale and that the subsequent sale was effected pursuant to a Rule 10b5-1 trading plan, which provides an affirmative defense when properly adopted and executed. The Form 4 was executed by an attorney-in-fact and includes the required explanations.

From a compliance perspective, ensure the trading-plan adoption date and execution cadence remain documented; note any deviations would be visible in later Form 4 filings within standard reporting windows.
