Firefly Aerospace Inc. has filed an S-1 to register 12,000,000 shares of Common Stock. The company is offering 4,000,000 shares, while selling securityholders are offering 8,000,000 shares, with an additional 1,800,000 shares available to underwriters under an option.
Firefly estimates net proceeds of about $190.1 million from its portion of the sale, assuming a $49.50 per share price, and plans to use the cash for general corporate purposes and to support growth of its core business and recently awarded programs. As of March 31, 2026, 160,067,383 shares of Common Stock were outstanding.
The company highlights its position as a space and defense technology provider with launch vehicles and spacecraft solutions, and notes a recent $75 million award from NASA’s Jet Propulsion Laboratory for the MoonFall mission.

Firefly Aerospace is registering the resale of up to 11,111,116 shares of Common Stock issued to the SciTec sellers, valued at $555.6 million based on $50.00 per share. These shares were paid as stock consideration in the acquisition of SciTec Innovations, and any sales will be made from time to time by the selling securityholders, not by the company.
Firefly will not receive any proceeds from these sales, though it will cover registration expenses while the selling holders pay any underwriting discounts and their own costs. The SciTec holders are restricted from transferring the shares until February 7, 2026. Shares outstanding were 159,251,122 as of November 10, 2025; this is a baseline figure, not the amount being offered.
The company positions itself as a market-leading space and defense technology provider, with its Alpha launch vehicle already in orbit and the larger Eclipse vehicle in development. It recently closed the SciTec acquisition to strengthen AI-enabled defense software capabilities and add more than 475 specialized employees. Firefly is an emerging growth and controlled company, has recorded sizeable net losses and depends heavily on a small number of major and U.S. government customers, and it highlights extensive operational, budget, launch and supply-chain risks for investors to consider.
