AMBQ — Insider Trading Activity
3 insiders sold outside 10b5-1 plans in 30 days at AMBQ, outside any pre-arranged Rule 10b5-1 plan, and not alone.
What this means for AMBQ
AMBQ is not showing a cluster buy or a step-change versus its own baseline, so what the window amounts to is selling only. Unusual selling. 3 insiders sold outside 10b5-1 plans in 30 days, and more than one insider sold inside the same window. None of it was executed under a pre-arranged Rule 10b5-1 plan, so the timing was the insider’s own choice — $1M–$5M of discretionary selling in total.
By the numbers. No insider at AMBQ filed an open-market purchase in the last 90 days. On the other side, 5 insiders filed 50 sales covering 339,387 shares at an average of $60.91, the latest on October 5, 2026.
