Insights

Securities Trading Expert

Routine tax-cover sales executed partly under a 10b5-1 plan.

The transactions show 7,627 shares sold across 10/02/2025 and 10/03/2025

One set of sales is identified as executed under a 10b5-1 trading plan adopted on 06/05/2025, which provides an affirmative defense to insider trading claims when properly structured. The reported weighted average prices ranged from $10.81 to $11.30

Watch for future Form 4s over the next few reporting periods to confirm whether this is a one-time tax-cover event or part of a continuing disposition schedule.

Corporate Governance Analyst

Disclosure is consistent and identifies motive and plan-based execution.

The filing explicitly states the sales satisfied tax liabilities from released restricted stock units and discloses the 10b5-1 adoption date, which strengthens governance transparency. The post-transaction direct ownership is reported as 65,960 shares, providing a clear ownership snapshot.

Governance stakeholders will note the transparent explanation and the willingness to provide per‑price details on request; any material change in ownership levels should appear on subsequent filings within the normal reporting cadence.
