Insights

Securities Analyst

TL;DR: Director adds 2,042 AM shares; total now 105,206—incremental, low-impact insider buy.

The Form 4 shows a modest acquisition that increases David H. Keyte’s direct stake by roughly 2% to 105,206 shares. With no accompanying sales or derivative exercises, insider exposure has inched higher, but the absolute size is small relative to the company’s share count. The filing is routine and does not materially alter the overall insider ownership profile, so market impact is expected to be limited.
