York Space Systems, which makes satellites and mission-critical systems for space and defense programs, filed on Monday with the SEC to raise what we estimate could be up to $400 million in an initial public offering.

Its spacecraft suite includes its S-CLASS, LX-CLASS, and M-CLASS families. York is the number one provider to the Department of Defense PWSA program by spacecraft operating in orbit (33), number of contracts (6), and variety of contract types, and has logged over 4 million on-orbit hours across 74 missions and 17 flight-heritage products. The company operates more than 45 ground antennas worldwide.
The Denver, CO-based company was founded in 2012 and booked $357 million in revenue for the 12 months ended September 30, 2025. It plans to list on the NYSE under the symbol YSS.
