Firefly Aerospace CEO Jason Kim sits for an interview at the Firefly Aerospace mission operations center in Leander, Texas, U.S., July 9, 2025. Firefly Aerospace has lifted the share price range for its upcoming initial public offering in a move that would value the space technology company at more than $6 billion. The lunar lander and rocket maker said in a filing Monday that it expects to price shares in its upcoming IPO between $41 and $43 apiece. Firefly's new target range would raise nearly $697 million at the top end of the range. That's up from the previously expected $35 to $39 price per share that Firefly announced in a filing last week, which targeted a $5.5 billion valuation. Firefly announced plans to go public last month as interest in space technology gains steam, and billionaire-led companies such as Elon Musk's SpaceX rake in more funding.
