Approach 1: AST SpaceMobile Discounted Cash Flow (DCF) Analysis
A Discounted Cash Flow, or DCF, model estimates what a stock could be worth by projecting future cash flows and discounting them back to today using a required rate of return.
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 $1,712.8 million and analyst based estimates point to continued free cash flow losses through 2028, followed by positive free cash flow of $538.2 million in 2029 and $1,068.3 million in 2030. Beyond the explicit analyst period, Simply Wall St extrapolates cash flows using its own assumptions to complete the projection.
On this basis, the DCF model arrives at an estimated intrinsic value of $138.34 per share, compared to the recent share price of $107.29. That indicates the stock is trading at a discount of about 22.4% on this cash flow view.
Result: UNDERVALUED
Our Discounted Cash Flow (DCF) analysis suggests AST SpaceMobile is undervalued by 22.4%. Track this in your watchlist or portfolio, or discover 46 more high quality undervalued stocks.

Approach 2: AST SpaceMobile Price vs Book
For companies that are still building up earnings, price based on book value can be a useful cross check because it compares what you pay for the stock with the accounting value of the business on the balance sheet.
In general, higher growth expectations and lower perceived risk can justify a higher multiple, while slower growth prospects or higher uncertainty often line up with a lower, more conservative multiple. That context helps frame what looks like a “normal” or “fair” P/B ratio for a stock.
AST SpaceMobile currently trades on a P/B of 15.41x. This compares with a Telecom industry average P/B of 1.49x and a peer average of 12.15x, so the stock is priced well above both broad and closer benchmarks on this metric.
Simply Wall St’s “Fair Ratio” is its own estimate of what a suitable P/B might be, based on factors such as earnings growth, profit margins, industry, market cap and key risks. Because it uses company specific inputs rather than broad group averages, this Fair Ratio can give a more tailored reference point than a simple comparison with peers or the wider industry.
There is no Fair Ratio figure available here, so this approach alone cannot indicate whether the current P/B suggests the stock is overvalued, undervalued or about right.
Result: ABOUT RIGHT

Upgrade Your Decision Making: Choose your AST SpaceMobile Narrative
Earlier it was mentioned that there is an even better way to understand valuation. Meet Narratives, a simple framework on Simply Wall St’s Community page where you link your view of AST SpaceMobile’s story to a concrete forecast for revenue, earnings and margins, then to a Fair Value that you can compare with today’s price to decide whether the stock looks attractive. Each Narrative updates automatically as new news or earnings arrive, and different investors express very different views, such as an optimistic Fair Value of US$524.70 at the high end and US$0.28 at the low end.
For AST SpaceMobile however, we’ll make it really easy for you with previews of two leading AST SpaceMobile Narratives:
On Simply Wall St’s Community page, investors have already laid out detailed bullish and bearish stories that connect business assumptions to a concrete fair value per share. Here is how two of the most followed Narratives line up side by side.
Fair value in this bullish Narrative: US$170.00 per share
Implied discount to that fair value at the recent US$107.29 share price: about 36.9% below the Narrative fair value
Revenue growth assumption used in the Narrative model: 284.87%
-
The Narrative sees AST SpaceMobile as a high risk, high potential “execution driven moonshot” that could become important space based cellular infrastructure if the satellite rollout and carrier partnerships progress as planned.
-
It highlights Q1 2026 revenue of US$14.7 million, management’s 2026 revenue guidance of US$150 million to US$200 million, a target of around 45 BlueBird satellites in orbit by year end 2026, and a reported cash balance of about US$3.5b as factors that support the long term build out plan.
-
The author sets an optimistic fair value of US$170 per share, while stressing that this outcome relies on successful execution across deployment, commercialization with mobile network operators and government work, and that the wide range of potential outcomes keeps risk high.
Fair value in this bearish Narrative: US$40.00 per share
Implied premium to that fair value at the recent US$107.29 share price: about 168.2% above the Narrative fair value
Revenue growth assumption used in the Narrative model: 335.17%
-
This Narrative argues that at higher share prices AST SpaceMobile was already pricing in a very optimistic future, with the stock framed more as a momentum trade than a growth investment once factors such as reported free cash flow burn and cash runway are taken into account.
-
The author anchors fair value using a scenario where revenue reaches US$3b by 2029, EBITDA margin is 30%, and the business is valued on a 15x EV/EBITDA multiple, which leads to a present fair value range of US$25 to US$55 per share versus the higher market price figures cited in the Narrative.
-
Key concerns include the scale of expected capital needs, the possibility of further dilutive funding, competition after Amazon’s acquisition of Globalstar, and execution risk around satellite deployment and commercial launches with carriers such as TELUS Canada.
Taken together, these Narratives show how investors looking at exactly the same company and public data can reach very different views on fair value, risk and upside. If you want to see the full assumptions, forecasts and reasoning behind each side of the debate in one place, the Community Narratives on Simply Wall St set it all out in detail.
