Gravitics Holdings, focused on the research and development of large space structures and orbital systems, submitted its IPO filing to the U.S. Securities and Exchange Commission (SEC) on Monday, July 20th, planning to raise up to $125 million in funds. The company is primarily engaged in the design, development, and commercialization of large space structures, including orbital launchers, cargo logistics spacecraft, and space station modules, targeting government and commercial customers. Its flagship commercial contract is a fixed-price agreement worth $125 million with Axiom Space.
