Firefly Aerospace Inc., the Texas-based space technology company, has raised the size of its upcoming initial public offering (IPO) to as much as $697 million, signaling strong investor interest in the rapidly growing commercial space sector.
According to a filing with the US Securities and Exchange Commission (SEC) on Monday, Firefly plans to sell 16.2 million shares at a price range of $41 to $43 per share. This marks an increase from the company’s earlier target of $35 to $39 per share.
At the top of this range, Firefly’s market capitalization would reach $6 billion, with a fully diluted valuation — including stock options and warrants — of roughly $6.8 billion. The IPO is expected to price on August 6, Bloomberg reported, citing a marketing presentation.
Rising Financial Ambitions
The company’s most recent earnings report showed a net loss of $60.1 million on $55.9 million in revenue for Q1 2025. This represents a significant revenue jump from $8.3 million in the same quarter last year, when Firefly posted a $52.8 million loss.
In May 2025, Firefly raised $50 million in a funding round led by Northrop Grumman Corp. The aerospace giant is collaborating with Firefly to develop a next-generation rocket for space station resupply missions, as well as commercial and national security launches.
Backed by Strong Investors
The company’s Series D-3 round earlier this year valued it at $2.95 billion, according to PitchBook data. Firefly is majority-owned by AE Industrial Partners, an aerospace and defense-focused private equity firm that acquired its stake in 2022 from Noosphere Venture Partners. Post-IPO, AE will retain majority voting control.
IPO Underwriters & Market Debut
Goldman Sachs, JPMorgan, Jefferies, and Wells Fargo are leading the offering. Firefly shares are set to list on the Nasdaq Global Market under the ticker FLY.
With growing demand for launch vehicles, spacecraft, and satellite delivery services, Firefly’s IPO could position it as one of the most closely watched space technology public debuts of 2025.
