ASTS — Insider Trading Activity

ASTS is not showing a cluster buy or a step-change versus its own baseline, so what the window amounts to is a single insider acting alone. Who is buying. The most credible buyer in this window is a Director ($500K–$1M), growing their stake by 1%. That insider’s track record: past buys beat the S&P 500 2 of 2 times (avg +48% vs S&P over 6 mo). Overall credibility score: 30/100 (Low).

By the numbers. One insider filed 3 open-market purchases at ASTS over the window, 10,822 shares in all at an average of $57.22 a share, most recently on August 31, 2026. On the other side, 2 insiders filed 2 sales covering 52,000 shares at an average of $58.92, the latest on September 16, 2026. That puts the average sale 3% above the average purchase — worth checking against where the stock trades today.

How we read these filings — which transaction codes count, how the cluster and credibility thresholds are set, and what the signals have and haven’t predicted — is written up in the insider trading methodology.
