Firefly Aerospace raised about $868 million in an upsized U.S. initial public offering after pricing 19.3 million shares at $45 apiece, above an already increased $41-$43 marketing range. The satellite-launch and lunar-lander company will begin trading today on the Nasdaq under the symbol FLY. The offering assigns the Cedar Park, Texas-based firm a market valuation of roughly $6.3 billion. Bookrunners said the deal was about 20 times oversubscribed, and pre-market indications pointed to an opening price of $68-$70, suggesting a first-day gain of more than 50%. Goldman Sachs, JPMorgan Chase, Jefferies and Wells Fargo led the syndicate. Proceeds are earmarked for repaying debt, settling preferred-stock dividends and general corporate purposes. Investor enthusiasm has been stoked by Firefly’s March mission that made it only the second private company to land on the Moon, underscoring growing public-market appetite for so-called New Space businesses. Separately, AI data-center operator WhiteFiber priced 9.4 million shares at $17, the top of its range. The stock, set to trade as WYFI, was indicated to open as high as $34, highlighting the broader rebound in U.S. IPO activity.
