Insights

Equity compensation and insider-trading analyst

CTO’s 40,000-share 10b5-1 sale looks sizable but pre-planned.

The Chief Technology Officer of AST SpaceMobile executed an open-market sale of 40,000 Class A shares at a weighted average price of $88.88. Trades occurred within a price range of $86.71 to $90.70, reflecting typical execution across multiple fills.

Following the sale, the CTO directly holds 4,750 shares, implying a significantly smaller remaining direct equity stake from this filing’s perspective. However, the transaction was conducted pursuant to a Rule 10b5-1 trading plan adopted on June 12, 2025, which suggests the sales were scheduled in advance and reduces the informational value of their specific timing.

There are no derivative positions listed in this filing’s derivative summary, so the visible equity exposure consists of the remaining 4,750 directly held shares. Future company filings may clarify any additional equity awards or plans affecting the executive’s longer-term ownership profile.
