On May 19, 2026, satellite manufacturer York Space Systems (NYSE: YSS) announced a definitive merger agreement to acquire Solestial, Inc., an Arizona-based pioneer in next-generation space solar technology.

The acquisition follows two other multi-million-dollar deals completed earlier in the year:
