Jason Kim, chief executive officer of Firefly Aerospace, center, during the company's initial public offering at the Nasdaq MarketSite in New York, US, on Thursday, Aug. 7, 2025.
Firefly Aerospace stock climbed 9% Monday, after the space company said it's buying defense technology contractor SciTec for $855 million as it looks to strengthen its national security offering.
The deal, announced Sunday, is slated to close at the end of the year and includes $300 million cash and $555 million in Firefly shares.
"These capabilities significantly enhance our ability to deliver integrated, software-defined solutions for critical national security imperatives, particularly Golden Dome," said CEO Jason Kim in a release.
The company plans to integrate SciTec's software into its tools. Capabilities such as missile warning, tracking and defense and autonomous command control will also support Firefly's launch and space services, the company said.
