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

A Discounted Cash Flow, or DCF, model takes projected future cash flows, then discounts them back to today to estimate what the business might be worth now. It is essentially asking what those future dollars are worth in today’s money.

For AST SpaceMobile, the latest twelve month free cash flow (FCF) is a loss of $1,438.9m, so the model starts from a deeply negative cash position. Analysts have provided FCF estimates out to 2030, with Simply Wall St extrapolating further to build a 2 Stage Free Cash Flow to Equity model. Within this, annual projections move from losses in 2026 and 2027 into positive FCF by 2029, reaching $975.6m in 2030, all in $.

When all these projected cash flows are discounted back, the DCF model arrives at an estimated intrinsic value of about $133 per share. Against a recent share price of $76.40, this implies the stock is 42.6% undervalued on these assumptions.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests AST SpaceMobile is undervalued by 42.6%. Track this in your watchlist or portfolio, or discover 56 more high quality undervalued stocks.

Approach 2: AST SpaceMobile Price vs Book

For companies where earnings are not yet a steady guide, price based on book value can be a helpful cross check, because it compares what you pay in the market to the net assets on the balance sheet. Investors usually accept a higher or lower price to book ratio depending on growth expectations, quality of assets and perceived risk, so there is no single “right” level across all businesses.

AST SpaceMobile currently trades on a P/B of 12.14x. That is higher than the Telecom industry average P/B of 1.52x and also above the selected peer group average of 10.59x. Simply Wall St’s “Fair Ratio” is a proprietary estimate of what the P/B might be, given factors such as the company’s growth profile, profit margins, risk factors, industry and market cap. This tailored approach aims to be more precise than a simple comparison with peers or the broad industry, which may not share the same risk and growth characteristics.

In this case, AST SpaceMobile’s actual 12.14x P/B sits above the Fair Ratio estimate, which points to the shares looking overvalued on this metric alone.

Result: OVERVALUED

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

Fair Value: US$95.00

Implied undervaluation vs last close: around 19.6%

Revenue growth assumption: 394.61%

• Assumes AST SpaceMobile converts a large base of mobile network operator agreements and more than US$1b of contracted and prepaid revenue into recurring service income, supported by substantial cash and liquidity to fund a fleet of over 100 satellites.
• Reflects very strong improvements in profitability, with margins moving from deep losses today toward high positive levels, supported by vertically integrated production, scale benefits and AI driven spectrum management.
• Targets a Fair Value of US$95 based on bullish analyst expectations for revenue, earnings and P/E by 2028, while highlighting execution, cost control, spectrum access and partner commitment as key risks to that view.

Fair Value range: US$25.00 to US$55.00

Implied overvaluation vs last close: about 217.6% at US$25 and about 39.5% at US$55

Revenue growth assumption: 335.17%

• Emphasizes that at higher share prices the market is already pricing in a flawless future despite a reported annual cash burn of about US$1.2b and a finite cash runway, which could lead to further capital raises.
• Frames competition and partner behavior as central, pointing to Amazon’s entry via the Globalstar acquisition and the risk that carrier partners hedge their bets in ways that could pressure margins and limit the value of existing contracts.
• Builds a Fair Value range of US$25 to US$55 using revenue scenarios out to 2029, margin assumptions and EV/EBITDA multiples, and notes that any setback in satellite deployment or commercial launches could challenge the high market valuation.
