CEDAR PARK, Texas, October 5, 2025 – Firefly Aerospace (Nasdaq: FLY), a market leading space and defense technology company, has entered into a definitive agreement to acquire SciTec, Inc., a leader in advanced national security technologies, for approximately $855 million through a combination of $300 million in cash and $555 million in Firefly shares issued to SciTec owners at a price of $50 per share.

“The acquisition of SciTec enhances our ability to support a growing number of defense missions and provides us with a significant operational advantage,” said Jason Kim, CEO of Firefly Aerospace. “SciTec’s mission-proven software and big data processing capabilities provide warfighters with rapid, accurate information to enable informed decisions that protect our homeland from emerging threats. These capabilities significantly enhance our ability to deliver integrated, software-defined solutions for critical national security imperatives, particularly Golden Dome. We are excited to welcome the SciTec team to the Firefly family and look forward to working together to continue to deliver leading edge solutions to advance our country’s strategic advantage in space.”

The acquisition will advance Firefly’s comprehensive space services by adding mission-proven defense software analytics, remote sensing, and multi-phenomenology data expertise. SciTec’s core capabilities – which include missile warning, tracking and defense, intelligence, surveillance and reconnaissance, space domain awareness, and autonomous command and control – will supplement Firefly’s launch, lunar, and in-space services. SciTec further adds ground and onboard data processing as well as AI-enabled systems designed for low latency operations to support advanced threat tracking and response across multiple domains.

SciTec generated revenues of approximately $164 million for the twelve-month period ending June 30, 2025, driven by robust contracts supporting the intelligence community, defense and national security agencies, and commercial customers. Earlier this year, SciTec was awarded a $259 million contract by the U.S. Space Force to further enhance the Future Operational Resilient Ground Evolution (FORGE) framework. SciTec is delivering a scalable, cyber-secure ground processing capability to strengthen the Space Force’s missile warning and tracking mission and accelerate threat-responsive solutions for warfighters.

“We believe Firefly is the best home for our business and people,” said Jim Lisowski, CEO SciTec. “In addition to the strong strategic fit, our cultures are similar. Both teams are empowered, rapid innovators who are passionate about our critical missions and willing to take on near impossible tasks to ensure we protect our country from future threats. We share a unique focus on providing differentiated, leading-edge solutions to our customers.”

SciTec is headquartered in Princeton, N.J., and maintains five additional facilities strategically positioned near key space and defense customers.

The acquisition is expected to close by year end 2025, subject to regulatory approvals and customary conditions. Once finalized, SciTec will be operated as a Firefly subsidiary under its current business model led by Jim Lisowski, current CEO of SciTec, who will report to Firefly’s CEO Jason Kim.

Goldman Sachs & Co. LLC is serving as exclusive financial advisor and Kirkland & Ellis LLP is serving as legal advisor to Firefly. Baird is serving as exclusive financial advisor and Cooley LLP is serving as legal advisor to SciTec.
