Approach 1: AST SpaceMobile Discounted Cash Flow (DCF) Analysis

A DCF model takes estimates of the cash a business could generate in the future, then discounts those cash flows back to today to arrive at an implied value per share.

For AST SpaceMobile, the model uses a 2 Stage Free Cash Flow to Equity approach based on cash flow projections in $. The latest twelve month free cash flow is a loss of $1,078.1m. Analyst and extrapolated forecasts in the model point to free cash flow of $1,122.2m in 2030, with a path that includes negative and positive years between 2026 and 2035 as set out in the ten year projection table.

When all of those projected cash flows are discounted back to today, the model arrives at an estimated intrinsic value of $102.38 per share, compared with the recent share price of $85.73. That gap implies the shares trade at a 16.3% discount to this particular DCF estimate.

Approach 2: AST SpaceMobile Price vs Book

For companies that are still building toward consistent profitability, the price to book, or P/B, ratio can be a useful way to think about value because it compares the market price to the accounting value of assets rather than current earnings.

In general, investors tend to accept a higher P/B ratio when they expect stronger growth and are comfortable with the risk profile, while slower expected growth or higher risk usually lines up with a lower, more conservative multiple.

AST SpaceMobile currently trades on a P/B ratio of 19.41x. That compares with an average P/B of 1.13x for the wider Telecom industry and 6.14x for its peer group, which highlights how different the market’s expectations appear to be for this company versus more established operators.

Simply Wall St’s Fair Ratio is a proprietary estimate of what a reasonable P/B might look like once you factor in elements such as earnings growth, profit margins, industry, market cap and specific risks, rather than just lining it up against broad industry or peer averages.

Because the Fair Ratio figure for AST SpaceMobile is not available here, you cannot yet make a clean call on whether 19.41x suggests the shares are overvalued, undervalued or about right using this framework alone.

Upgrade Your Decision Making: Choose your AST SpaceMobile Narrative

Earlier we mentioned that there is an even better way to think about valuation, so let us introduce you to Narratives, which let you attach a clear story to the numbers you are using for fair value, future revenue, earnings and margins.

A Narrative is simply your view of how a company’s story might play out, translated into a forecast and then into a fair value that you can compare with today’s price.

On Simply Wall St, Narratives are available on the Community page and are used by millions of investors as an accessible way to set assumptions, see the implied fair value and then decide whether the gap between Fair Value and Price suggests an opportunity or a warning for their own situation.

These Narratives update automatically when new information such as news or earnings is added to the platform, so your story and valuation stay aligned without you rebuilding a model each time.

For example, one AST SpaceMobile Narrative on the Community page might assume very strong future adoption and place fair value well above US$85.73. Another might use more cautious forecasts and put fair value well below the current price, which shows how two investors can reasonably land in very different places using the same tool.
