York Space Systems Awarded Multiple IDIQ Awards Supporting Next-Generation National Security Space Architectures

York Space Systems (York) (NYSE:YSS), a leading, U.S.-based national defense and commercial prime providing a comprehensive suite of mission-critical solutions, today announced it has secured multiple IDIQ contract awards across two mission areas critical to national security and defense. These awards expand York's role in next-generation space and defense architectures.

The work supports the development and deployment of critical national defense and warfighter space capabilities, including systems relevant to emerging, highly integrated missions, like Golden Dome.

"These awards reinforce the continued confidence government customers place in York to deliver on complex national security missions," said Michelle LeMar, VP of Business Development for York. "We remain focused on disciplined execution and delivering capabilities that meet the government's most demanding requirements."

York will compete for, and is well-positioned to win and execute, task orders under the IDIQ through its resilient U.S. supply chain and high-rate manufacturing capability, backed by numerous successful deliveries across national security and commercial missions.

As demand grows, York continues to scale its operations to support increasing demand. With 33 satellites currently on orbit and mission operations centers actively supporting five missions, including two operational constellations, York is broadening its role across a diverse portfolio of national security and commercial programs.
