Price-to-Book of 22.8x: Is it justified?

With AST SpaceMobile’s last close at $71.15, its price-to-book ratio sits at 22.8x, making the stock appear significantly more expensive than both its peers and the industry average.

The price-to-book ratio compares a company's market value to its balance sheet equity. This measure helps highlight how much investors are paying versus the company’s net assets. For a capital-intensive sector like telecom, this metric is often used to gauge whether the market is pricing in future growth or over-optimism.

In this case, AST SpaceMobile’s price-to-book ratio is over four times the peer average of 5.4x and far exceeds the US Telecom industry average of 1.2x. Such a premium suggests investors expect transformative growth, but it raises questions as to whether those expectations are sustainable given the company’s lack of meaningful revenue and recurring losses.

Result: Price-to-Book of 22.8x (OVERVALUED)

However, persistent losses and a price below analyst targets highlight real risks. These factors could challenge the current optimism around AST SpaceMobile’s valuation.
