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

Spirit AeroSystems is currently trading at a price-to-sales (P/S) ratio of 0.7x, which places it at a premium relative to its own estimated fair P/S ratio of 0.4x. Since the most recent closing price was $38.56, this ratio suggests that the market is attaching more value to each dollar of revenue than what the fair ratio would indicate.

The price-to-sales ratio measures how much investors are willing to pay per dollar of the company’s sales, making it especially useful when companies have volatile or negative earnings. For an unprofitable company like Spirit AeroSystems, P/S can offer a clearer picture of relative value than profit-based multiples.

While Spirit AeroSystems’ sales metric looks expensive compared to its own fair value benchmark, it appears attractively valued when compared to both its peer group (average 11.6x) and the broader US Aerospace & Defense industry (average 3.1x). This significant gap suggests the market may be skeptical about the company’s path to sustainable profits, or is discounting potential risks more sharply than it does for industry peers. If the market moves closer to the fair ratio, investors could see a shift in sentiment.
