Insights

Corporate Governance Analyst

Director received a stock award of 199 shares, increasing reported beneficial ownership to 12,402 shares.

The Form 4 discloses an equity award granted 10/01/2025 under the company’s 2024 Omnibus Equity Plan. The award is recorded at a $0 price, reflecting a grant rather than a market purchase.

This is a routine insider equity grant and is material as required by Section 16 reporting rules because it updates insider ownership levels; however, the absolute size (199 shares) is modest relative to total outstanding common stock and therefore likely has limited economic impact.
