AST SpaceMobile filed this prospectus supplement on April 1, 2022 to update its satellite broadband network development plan, with the company targeting commercial satellite launches beginning in 2023 and expecting to achieve substantial global coverage by end of 2024 after deploying 110 satellites, followed by full MIMO capabilities in 2025 with 168 satellites. The company had approximately 386 employees worldwide and an estimated $1.9 billion capital requirement to build and launch its full constellation of 168 high-powered LEO satellites designed to provide direct cellular broadband to standard mobile phones through partnerships with mobile network operators covering roughly 1.8 billion subscribers globally. As of March 31, 2022, AST SpaceMobile had incurred approximately $70.5 million in cumulative net losses since inception, with the company remaining pre-revenue as it continued advancing its BlueWalker 3 test satellite toward a summer 2022 launch to validate the technology stack for commercial BlueBird satellites.
