Why AST SpaceMobile Stock Jumped 14.1% Today

AST SpaceMobile stock surged 14% following an announcement of a joint venture with Japanese carrier Rakuten to provide satellite cell service to underserved areas in Japan. However, the company's Q3 revenue of $42.3 million missed Wall Street expectations, though it maintained its full-year guidance of $150-200 million and expects to launch intermittent U.S. coverage by year-end.
