Firefly Aerospace (FLY): Valuation in Focus After Rocket Test Failure and Sharply Lower Share Price

Simply Wall St · 10/03/2025 21:39

Firefly Aerospace (FLY) is under the microscope after its Alpha Flight 7 rocket exploded during a preflight test. This incident sent shares tumbling and intensified investor unease about the company’s reliability and commercial future.

See our latest analysis for Firefly Aerospace.

Shares of Firefly Aerospace rallied after its August IPO but quickly lost altitude, with the 30-day share price return slipping and investor sentiment cooling in the wake of its Alpha rocket mishap and disappointing quarterly results. Despite headline-grabbing NASA contract wins and a recent S&P TMI Index addition, the momentum has faded as risk perceptions rise and the company’s early promise faces real world setbacks.

Amid these turbulent launches and shifting momentum, it could be the perfect time to see which other aerospace innovators are on investors’ radar. See the full list for free.

With shares now trading at a sharp discount to analyst targets after disappointing results and rocket setbacks, is the market overlooking Firefly's long-term potential, or is all of the risk already priced in?

Price-to-Sales Ratio of 38.2x: Is it justified?

Firefly Aerospace is trading at a price-to-sales ratio of 38.2x, placing the stock at a sharp premium compared to both its direct peers and the broader US Aerospace & Defense sector.

The price-to-sales (P/S) ratio compares the company’s stock price to its revenues. This metric is especially relevant for early-stage aerospace firms that may not yet be profitable, as it helps investors gauge expectations for future revenue growth relative to what the market is willing to pay today.

At 38.2x, Firefly’s ratio stands far above the US Aerospace & Defense industry average of 3.4x and also exceeds the peer group average of 2.7x. This steep multiple suggests the market is pricing in aggressive growth expectations or placing a premium on the company’s position in a high-potential but volatile market segment.

Result: Price-to-Sales ratio of 38.2x (OVERVALUED)

However, persistent revenue losses and recent share price declines could further erode investor confidence if commercial growth targets are not met soon.
