Organization and Nature of Operations	1. Organization and Nature of Operations AST SpaceMobile, Inc., collectively with its subsidiaries (“SpaceMobile” or the “Company”), is currently designing, developing and manufacturing the constellation of BlueBird (“BB”) satellites and has begun launching its planned space-based Cellular Broadband network distributed through a constellation of low Earth orbit (“LEO”) satellites. Once deployed and operational, the BB satellites are designed to provide connectivity directly to off-the-shelf and unmodified devices at broadband speeds (the “SpaceMobile Service”), and be accessible for other applications for government use. At that point, the Company intends to offer the SpaceMobile Service to cellular subscribers and others through wholesale commercial agreements with cellular service providers. The Company is headquartered in Texas where it operates 194,000 square feet of satellite assembly, integrating and testing (“AIT”) facilities. The Company’s intellectual property (“IP”) portfolio is diverse, containing numerous and various innovations of the direct-to-cell satellite ecosystem from space to Earth. The Company’s IP portfolio consists of 36 patent families worldwide. As of March 31, 2025, the Company has more than 3,650 patent and patent pending claims worldwide, of which approximately 1,650 have been officially granted or allowed. The Company launched its Blue Walker 3 (“BW3”) test satellite on September 10, 2022, and announced the completion of the deployment of the communication phased array antenna of the BW3 test satellite in orbit on November 14, 2022. Using the BW3 test satellite, the Company successfully completed two-way 5G voice calls directly to standard unmodified smartphones, achieved repeated successful download speeds of above 21 megabits per second (“Mbps”) to standard unmodified smartphones and spectral efficiency of approximately 3 bits per second per hertz. The Company has also successfully completed initial in-orbit and ground testing for non-communication government applications. The Company intends to continue testing capabilities of the BW3 test satellite, including further testing with cellular service providers and the government. The Company launched five first generation commercial BB satellites (“Block 1 BB satellites”) on September 12, 2024. The Block 1 BB satellites are of similar size and weight to the BW3 test satellite and have ten times higher throughput than the BW3 test satellite. In October 2024, the Company completed the deployment of the communication phased array antennas and Q/V antennas in orbit and performed a series of monitoring tests and activities to confirm the successful initial operations of the Block 1 BB satellites. In January 2025, the Company successfully made the first video call from space with Vodafone using standard unmodified 4G/5G smartphones. In February 2025, the Company completed the voice and video calls tests on standard unmodified smartphones with AT&T and Verizon in the U.S. and also completed the tests for non-communication applications for the United States government. All five Block 1 BB satellites have participated in the tests at various stages. In April 2025, together with Rakuten Mobile, Inc., the Company successfully conducted a two-way broadband video call in front of a live audience using unmodified smartphones on the SpaceMobile network enabled by a Block 1 BB satellite in orbit today. The Company expects to continue testing for SpaceMobile Service automation including beta testing prior to rollout of initial noncontinuous SpaceMobile Service in select markets including the United States, Europe, and Japan. On April 6, 2021, the Company completed a business combination (the “Business Combination”) with AST & Science, LLC (“AST LLC”). Following the consummation of the Business Combination, the Company is organized in an “Up-C” structure in which the business is operated by AST LLC and its subsidiaries and in which the Company's only direct assets consist of equity interests in AST LLC. As the managing member of AST LLC, the Company has full discretion to manage and control the business of AST LLC and to take all action it deems necessary to accomplish the purposes of AST LLC. The Company’s Class A Common Stock is listed on the Nasdaq Capital Market under the symbol “ASTS”. The Company operates from multiple locations that include its corporate headquarters and 194,000 square feet of AIT facilities in Texas where the final AIT is performed, engineering and development centers in the United States, India and Scotland, and engineering, development and production centers in Spain and Israel.
