Firefly Aerospace CEO Jason Kim sits for an interview at the Firefly Aerospace mission operations center in Leander, Texas, on July 9, 2025.
Firefly Aerospace will price shares at $35 to $39 each in its upcoming initial public offering, a deal that would value the rocket maker at about $5.5 billion.
The Texas-based space company said in an updated prospectus Monday that it's planning to sell about 16.2 million shares. The offering could raise up to $631.8 million.
Earlier this month, Firefly filed its plans to go public on the Nasdaq under the ticker symbol "FLY."
Its debut comes amid a renewed push in the space race, as billionaire-led companies such as Elon Musk's SpaceX funnel more money into space activities and startups try their luck at the public markets.
Space tech firm Voyager went public in June, while reusable rocket developer Innovative Rocket Technologies said it plans to debut through a $400 million special purpose acquisition company merger.
