York Space Systems Inc. (YSS)

York Space Systems Inc. is an aerospace company based in Denver, Colorado, whose common stock trades on the New York Stock Exchange. Founded in 2012, York designs and manufactures satellites and spacecraft platforms, known as buses, built on a standardized and repeatable production approach.

The company provides end-to-end space missions, combining spacecraft production with launch coordination and on-orbit mission operations through its own software and ground systems. This model is intended to deliver satellites faster and at lower cost than traditional custom-built spacecraft.

York's customers are primarily U.S. government and defense organizations, including the Space Development Agency, for which it builds satellites for low Earth orbit constellations supporting military communications and tracking. It also serves commercial and civil space customers.
