Price-to-Sales of 0.7x: Is it justified?

At a price-to-sales ratio of 0.7x, Spirit AeroSystems sits well below its US Aerospace & Defense sector peers, yet the company remains unprofitable at present. The last close price of $35.87 reflects a significant discount to both the industry average and the company’s robust annual revenue growth.

The price-to-sales ratio compares a company’s stock price to its revenues, offering investors a way to value businesses that might not yet be profitable. In aerospace manufacturing, this multiple can reveal whether the market is pricing in future growth, operational turnaround, or ongoing risks.

Spirit AeroSystems’ 0.7x price-to-sales ratio is not just low in absolute terms; it is substantially cheaper than the sector, where peers average 2.9x. Even compared to the peer group’s 2.5x, SPR stands out as a relative bargain. If the market shifts back toward the sector fair ratio, there could be notable upside.
