Insights
Large holder adopts plan to sell up to half its stake.
Rakuten Mobile, a key shareholder of AST SpaceMobile, reports ownership of 26,080,155 Class A shares, or 8.9% of the company, through this amended Schedule 13D. This confirms its role as a significant but non-controlling investor.
The amendment discloses an April 14, 2026 trading plan with BofA Securities covering up to 15,510,077 shares, about half of Rakuten’s position and 5.3% of outstanding stock. It also lists recent open-market sales totaling 4,940,000 shares at prices between $86.2211 and $91.4194.
Potential effects depend on how many shares are ultimately sold, since Rakuten Mobile can terminate the plan at any time. Future company disclosures that update ownership levels or report additional share sales will help clarify the ongoing impact of this trading plan.
