Firefly Aerospace Inc. (FLY) experienced a pre-market plunge of 5.10%, reversing its recent rebound as selling pressure resumed during the early trading session.

The decline is attributed to broad weakness across the Aerospace & Defense sector, with several key industry players also trading lower, creating a negative market environment for the stock. Additionally, investors are engaging in profit-taking following the stock's sharp rally in the prior two sessions, capitalizing on gains after the price recovered to elevated levels.

Despite Firefly Aerospace reporting strong quarterly results, including 45% year-over-year revenue growth and a significant U.S. Space Force contract secured by its subsidiary, the combination of sector headwinds and tactical selling has driven the pre-market decline.
