Firefly Aerospace stock has fallen 48.4% over the past year, yet valuation checks still suggest the shares look expensive rather than like a clear bargain.

• Over the last 12 months the share price has declined 48.4%, which means recent buyers have taken on significant price pressure.
• New contracts with the U.S. Space Force, NASA and Lockheed Martin can support long term revenue expectations. However, delays to the Alpha Block 2 rocket and execution risks around new programs may influence how investors price that potential growth.
• Firefly Aerospace scores just 2 out of 6 on our valuation checks, which points to a stock that currently leans expensive on broader metrics rather than clearly undervalued.

The key question now is whether Firefly Aerospace's current price offers enough compensation for these risks and opportunities, based on what investors are willing to pay for the stock today.

Has Firefly Aerospace Run Too Far on Sales?

P/S is often the cleanest way to look at Firefly Aerospace because the company is still building towards consistent profitability and cash flows.

Firefly Aerospace trades on a P/S multiple of about 13.5x, compared with an Aerospace & Defense industry average near 4.4x and a peer average around 4.4x. The fair P/S ratio from the model, which blends factors like growth expectations, margins and risk, is closer to 6.1x. That is less than half of where the stock is currently priced.

Despite contracts such as the recent U.S. Space Force radar deal helping support revenue expectations, the share price still reflects a rich sales multiple relative to both sector norms and the tailored fair ratio. This suggests investors are paying a high price today for each dollar of Firefly Aerospace revenue.

On the P/S multiple, Firefly Aerospace currently screens as overvalued.

The Bottom Line

Firefly Aerospace still trades on a P/S multiple that screens as overvalued compared with sector peers and the tailored fair ratio. That premium leaves little room for disappointment if contract execution, rocket development or new program timelines turn out to be slower or bumpier than the market currently assumes. The crux for investors is whether Firefly Aerospace can deliver enough reliable revenue growth and margin progress to make today’s rich sales multiple feel justified rather than exposed.
