A Discounted Cash Flow, or DCF, model estimates what a business might be worth by projecting its future cash flows and then discounting those back to today’s value.
For AST SpaceMobile, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is a loss of about US$1,438.9 million, and analyst based and extrapolated estimates suggest free cash flow staying negative in 2026 and 2027, then turning positive and reaching US$975.6 million by 2030. Beyond the explicit analyst window, Simply Wall St extrapolates further free cash flow projections out to 2035 using growth assumptions built into the model.
Aggregating and discounting these projected cash flows results in an estimated intrinsic value of about US$132.99 per share. Against a current share price around US$98.97, the model implies the stock trades at a 25.6% discount. This indicates a material gap between the cash flow based estimate and the market price.
Result: UNDERVALUED
Our Discounted Cash Flow (DCF) analysis suggests AST SpaceMobile is undervalued by 25.6%. Track this in your watchlist or portfolio, or discover 55 more high quality undervalued stocks.

For companies that are not yet producing consistent profits, price based multiples tied to the balance sheet, such as P/B, are often more practical than earnings based measures. They relate the market value of the equity to the accounting value of net assets, which can be easier to interpret when earnings are volatile or negative.
In general, investors tend to accept a higher “normal” valuation multiple when they expect stronger growth or see lower risk, and a lower multiple when growth expectations are modest or risks are higher. For AST SpaceMobile, the current P/B ratio is about 15.73x, compared with a telecom industry average of 1.33x and a peer group average of 9.42x. This means the shares trade at a higher level than both of those benchmarks.
Simply Wall St’s Fair Ratio is a proprietary estimate of what the P/B multiple might be, given factors such as earnings growth profile, industry, profit margins, market cap and risk characteristics. That tailored approach can be more informative than simple comparisons with industry or peer averages, because it explicitly adjusts for the company’s own fundamentals and risk profile. In this case, without a specific Fair Ratio value, the comparison cannot be completed, so no clear judgment can be made on whether the shares look overvalued, undervalued or about fair on a P/B basis.

Earlier it was mentioned that there is an even better way to understand valuation. Narratives are used to connect your view of AST SpaceMobile’s story with clear numbers by letting you set assumptions for future revenue, earnings and margins, link those to a Fair Value, and then compare that Fair Value with the current price inside the Simply Wall St Community page. Narratives update automatically as news or earnings arrive. One investor might build a higher Fair Value Narrative that leans on expectations similar to the US$95.00 bullish target, while another might prefer a lower Fair Value closer to the US$43.00 bearish target. Seeing those side by side makes it easier to decide whether the current share price looks above or below the range that fits your own view of the business.
