Insights

Financial Analyst

TL;DR: Insider purchased a small block (500 shares) at $48.52; stake after purchase is 93,952 shares, indicating continued ownership rather than material accumulation.

The purchase of 500 shares at $48.52 is a factual insider buy but represents a small change relative to the total beneficial ownership reported (93,952 shares). The filing discloses restricted stock grants totaling 9,334 shares subject to future vesting schedules and participation in the Employee Stock Purchase Plan for additional exempt acquisitions. From an analyst perspective, this transaction is informational and does not materially alter ownership percentages or signal a significant shift in alignment with shareholders given its modest size.

Corporate Governance Expert
