Assessing Firefly Aerospace (FLY) Valuation After a Sharp 3-Month Share Price Decline

Firefly Aerospace (FLY) has had a choppy stretch lately, with the stock jumping about 8% in the last session but still sitting sharply lower over the past 3 months.

See our latest analysis for Firefly Aerospace.

That sharp 1 day share price return of 8.31% looks more like a brief relief rally than a trend change, given the roughly 55% 3 month and 66% year to date share price declines. These moves signal that sentiment and momentum are still fading despite the company’s growth story.

If Firefly’s recent volatility has you rethinking your exposure to the sector, this could be a good moment to explore other aerospace and defense stocks that might offer a different balance of risk and upside.

With analysts seeing upside to their target price and fundamentals showing rapid top line growth but steep losses, the key question now is whether Firefly is trading below its true potential or if the market already reflects its future trajectory.

Price-to-Sales of 28.7x: Is It Justified?

On a price-to-sales basis, Firefly Aerospace looks richly valued, with its 28.7x multiple sitting well above both peers and the broader Aerospace and Defense industry, despite the recent share price slide to 20.07 dollars.

The price-to-sales ratio compares the company’s market value with its revenue, a useful lens for high growth, loss making businesses where earnings are still negative. For Firefly, investors are effectively paying nearly 29 dollars for every 1 dollar of current sales, which assumes substantial future scaling and margin improvement to justify that premium.

Compared with the US Aerospace and Defense industry average of about 3x sales, as well as a peer average of roughly 2.9x, Firefly’s multiple is almost an order of magnitude higher. That gap suggests the market is already baking in aggressive growth and a successful transition to profitability, leaving less room for disappointment if execution or sector conditions fall short.

Result: Price-to-Sales of 28.7x (OVERVALUED)

However, significant ongoing losses and execution risk on ambitious launch and lunar programs could quickly challenge the premium valuation if milestones slip.

Another Angle: Our DCF Model Suggests It May Be Cheap

While the rich 28.7x sales multiple appears to indicate overvaluation, our DCF model suggests fair value around 52.29 dollars a share, about 61.6% above today’s price. Is the market putting a high price on sales yet underestimating long term cash generation potential?

Look into how the SWS DCF model arrives at its fair value.
