• Investors may be wondering whether AST SpaceMobile’s recent share price still leaves room for value, or if the stock has already run ahead of itself.
• The stock last closed at US$65.35, with a 1 year return of 158.8% and a very large 3 year gain. Over the shorter term, the 30 day return of a 29.4% decline and 7 day return of an 11.6% decline show sharp pullbacks that can change how investors think about risk and reward.
• Recent coverage has focused on AST SpaceMobile’s ambitious aim to build a space based cellular broadband network and its progress on launching and testing satellites. This has kept attention firmly on execution risk and funding needs. At the same time, headlines have highlighted the stock’s very large multi year share price move, which can make valuation a central question for anyone considering it now.
• Simply Wall St’s valuation checks give AST SpaceMobile a 3 out of 6 value score. The next sections will walk through the different valuation methods behind that result, and then finish with a way to get an even fuller picture of what the current price could mean for long term investors.

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 the company’s future cash flows and discounting them back to today’s dollars.

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 $1,438.9 million, and analyst inputs combined with Simply Wall St extrapolations indicate free cash flow turning positive over time, reaching $975.6 million in 2030. Between 2026 and 2035, the projections move from large losses to positive cash flows in the hundreds of millions of dollars each year. These figures are all expressed in US$ and then discounted back to today.

On this basis, the estimated intrinsic value from the DCF model is US$131.94 per share, compared with the recent share price of US$65.35. That implies the stock is about 50.5% undervalued according to this specific cash flow scenario.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests AST SpaceMobile is undervalued by 50.5%. Track this in your watchlist or portfolio, or discover 51 more high quality undervalued stocks.

Approach 2: AST SpaceMobile Price vs Book

For many profitable companies, price-based multiples are a straightforward way to think about valuation because they relate the share price to a familiar business metric like earnings, sales or the accounting value of net assets.

What investors consider a reasonable multiple often reflects how much growth they expect and how much risk they are willing to accept. Higher expected growth or lower perceived risk can support a higher multiple, while more uncertainty usually points to a lower one.

For AST SpaceMobile, the preferred metric is the P/B ratio. The stock trades around 10.60x book value, compared with a Telecom industry average of 1.40x and a peer average of about 10.80x. This already places the shares well above the broader sector, but broadly in line with closer peers.

Simply Wall St’s Fair Ratio is a proprietary estimate of what a company’s preferred multiple might be given its earnings growth profile, profit margins, industry, market cap and risk characteristics. This tailored yardstick can be more useful than simple peer or industry comparisons, which do not adjust for those differences.

In this case, the Fair Ratio is not available, so this approach cannot indicate whether the current P/B of 10.60x points to the stock being overvalued or undervalued.

Upgrade Your Decision Making: Choose your AST SpaceMobile Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so Narratives are introduced here as short, clear stories that you create about AST SpaceMobile, linking what you believe about its satellites, carrier partnerships, funding needs and competition to a financial forecast and then to a fair value that you can compare with the current share price.

On Simply Wall St’s Community page, Narratives let you set your own assumptions for future revenue, earnings, margins and even the P/E or P/B multiple. You can then instantly see how those inputs translate into a Fair Value that can sit anywhere from a more cautious view, such as a fair value range of about US$25 to US$55, through to a more optimistic view near US$95, all based on the same company but different expectations.

Because Narratives are refreshed when new updates like satellite launch news, carrier agreements or earnings numbers are added to the platform, you always see how your story stacks up against the latest information and how other investors are thinking about AST SpaceMobile. This can help you decide whether the gap between your Fair Value and the live Price points to an opportunity or a risk for your own portfolio.

For AST SpaceMobile however we'll make it really easy for you with previews of two leading AST SpaceMobile Narratives:

First are the investors who look at the same business and conclude that the current share price does not fully reflect its potential cash generation, balance sheet and commercial pipeline.

Fair value in this bullish narrative: US$95.00 per share

Implied undervaluation vs last close: about 31.2%

Revenue growth assumption: very large, around 395% a year

• Sees AST SpaceMobile as using a large pool of mobile network operator agreements, prepaid revenue commitments above US$1b and a cash and liquidity position of more than US$3.2b to scale a global space based cellular broadband network.
• Builds in very strong improvements in profitability, from a current loss position to profit margins in the 90% range within a few years, supported by vertically integrated satellite production and extensive spectrum access across S Band, L Band and more than 1,150 megahertz of tunable spectrum.
• Accepts bullish analyst assumptions that by around 2028 revenue could be about US$2.2b and earnings about US$2.1b, with the stock trading on a P/E of 18.8x, above the current US Telecom industry P/E of 8.9x, and then discounts those cash flows using a rate of about 7.0%.

On the other side are investors who focus more on cash burn, capital intensity and new competitive threats and decide that the recent share price already prices in very optimistic outcomes.

Fair value in this bearish narrative: about US$40.00 per share

Implied overvaluation vs last close: about 63.4%

Revenue growth assumption: very large, around 335% a year

• Starts from a context where the market value sits far above current revenue, with levered free cash flow of about US$1.19b in the red against cash of about US$2.34b, which limits the runway and makes further capital raises a key concern.
• Assumes AST SpaceMobile eventually scales to about US$3b of revenue by 2029 with EBITDA margin near 30%, then applies a 15x EV/EBITDA multiple and a 12% discount rate to arrive at a fair value range of roughly US$25 to US$55 per share, below a consensus analyst target of US$86.40.
• Flags competitive pressure from Amazon following its acquisition of Globalstar, the risk of carrier partners hedging their commitments, and execution risk around the larger BlueBird satellites and the pace of launches as potential triggers for a reset in expectations.

Taken together, these two narratives show how the same data on AST SpaceMobile can support very different conclusions about upside and downside. The key is which assumptions you find more reasonable for future revenue, margins, funding needs and competition, and how that lines up with your own risk tolerance and time horizon.
