Corporate Governance Expert

TL;DR: Insider purchases by the CEO and director are routine disclosures showing ownership increase.

The Form 4 reports multiple small open-market purchases by the company’s President and CEO, increasing his stake to 24,975 shares. This is a standard Section 16 disclosure of beneficial ownership changes and does not by itself indicate any corporate action beyond insider buying. Transaction sizes and prices are explicitly listed, and the filing is properly executed by power of attorney.
