With AST SpaceMobile now trading at US$70.89, you might be wondering whether the recent excitement around the stock still lines up with what it could be worth.

The share price has seen a mix of strong longer term returns, including 168.3% over the past year, alongside recent pullbacks of 7.2% over 7 days, 15.6% over 30 days, and 15.1% year to date. These movements can shift how investors think about both upside and risk.

Recent news coverage has focused on AST SpaceMobile's progress toward building space based mobile broadband and its efforts to scale a satellite constellation that aims to connect standard mobile phones directly. This has kept attention on execution risks, funding needs, and potential industry impact. In turn, that helps frame how investors interpret the sharp moves in the share price.

Right now the company holds a valuation score of 2 out of 6. The sections that follow will break down what different valuation methods say about that score, before finishing with a more complete way to think about value that goes beyond a single number.

AST SpaceMobile scores just 2/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

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

A Discounted Cash Flow model takes future cash flow projections and then discounts them back to today to estimate what the business could be worth in total and on a per-share basis.

For AST SpaceMobile, the model used is a 2 Stage Free Cash Flow to Equity approach. The company currently reports last twelve month free cash flow of a loss of $1,438.9 million. Analyst forecasts and subsequent extrapolations used by Simply Wall St project free cash flow reaching $975.6 million by 2030, with interim years moving from projected losses in 2026 and 2027 into positive territory from 2029 onward.

By discounting all of those projected cash flows back to today, the DCF model arrives at an estimated intrinsic value of about $132.99 per share. Compared with the current share price of $70.89, this implies the stock is 46.7% undervalued based on these assumptions and inputs.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests AST SpaceMobile is undervalued by 46.7%. Track this in your watchlist or portfolio, or discover 51 more high quality undervalued stocks.

Approach 2: AST SpaceMobile Price vs Book

For companies that are still building toward consistent profitability, price based metrics like P/B can be more useful than earnings based measures such as P/E, because they focus on what investors are paying relative to the net assets on the balance sheet rather than current profits.

Growth expectations and risk still matter though, since a higher growth and higher risk business will often trade at a higher “normal” multiple than a mature, lower risk peer. That is why it helps to compare any single ratio with a few reference points instead of viewing it in isolation.

AST SpaceMobile currently trades on a P/B of 11.27x. This sits above the Telecom industry average of 1.61x and also above the peer group average of 10.70x. This suggests investors are assigning a premium to the company’s equity base compared with many sector names.

Simply Wall St’s Fair Ratio is a proprietary estimate of what the P/B multiple could be, given the company’s earnings profile, industry, profit margin, market cap and specific risks. It aims to be more tailored than a simple comparison with peers, because it adjusts for growth, risk, profitability and size rather than assuming one benchmark fits all companies. In this case, the Fair Ratio is not available, so it is not possible to reach a clear conclusion on whether the current 11.27x P/B looks high, low or about in line with that model.

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, so Narratives are introduced here as a simple tool that lets you attach a clear story about AST SpaceMobile to specific numbers such as your own fair value range and assumptions for future revenue, earnings and margins. This way, the company’s story is directly linked to a financial forecast and then to a fair value you can compare with today’s US$70.89 share price.

On Simply Wall St’s Community page, Narratives are available for you to use by picking or adjusting a view that matches how you see the business. You can then compare the fair value for that view with the current price to help you judge whether AST SpaceMobile looks expensive, cheap or about in line for your assumptions, without needing to build a full model from scratch.

Narratives also update automatically when new information comes in, such as news about satellite launches or earnings. This means your fair value and key assumptions stay current instead of sitting in a static spreadsheet.

For example, one AST SpaceMobile Narrative on the platform applies a fair value range of US$25 to US$55 per share, while another uses a fair value of US$95. This shows how two investors can look at the same company, plug in very different expectations and then see those differences clearly reflected in their fair values and decisions.

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

These sit on opposite sides of the current US$70.89 share price, so together they give you a clear sense of how different assumptions can translate into very different fair values.

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

Implied discount to that fair value at US$70.89: about 25% below the narrative fair value.

Revenue growth assumption used: very large annual increase of about 4x per year.

• Assumes AST SpaceMobile converts more than US$1b of contracted and prepaid commitments from over 50 mobile network operator partners into recurring revenue, with a large addressable base of nearly 3 billion subscribers.
• Expects a fully funded balance sheet of over US$3.2b and vertically integrated production to support manufacturing and launching more than 100 satellites, while aiming for rising margins as scale builds.
• Builds in very high long term profitability and uses a future P/E of 18.8x on projected 2028 earnings, above the current US Telecom industry P/E of 8.9x, to justify a US$95.00 price target under a 6.96% discount rate.

Fair value used in this cautious narrative: midpoint of the US$25 to US$55 range, which is about US$40.00 per share.

Implied premium to that fair value at US$70.89: about 77% above the narrative fair value.

Revenue growth assumption used: very large increase over time that still results in a lower fair value than the current market price.

• Focuses on the gap between a roughly US$34.74b market value and US$70.9m of revenue, alongside levered free cash flow of about US$1.19b in the red, and estimates less than two years of runway at that burn rate against US$2.34b of cash.
• Works up to a scenario where revenue reaches about US$3b by 2029, EBITDA margin moves toward 30%, and a 15x EV/EBITDA multiple is applied, which points to an enterprise value that equates to roughly US$35 per share before higher growth and higher multiple cases lift the range to US$55.
• Highlights competition risk after Amazon’s acquisition of Globalstar, potential dilution from future capital raises, and execution risk around the BlueBird satellite program and carrier launches, which together keep the inferred fair value range well below recent trading levels.

Both Narratives use the same business, but plug in different views on execution, competition, margins and funding. The value for you as an investor comes from deciding which set of assumptions feels closer to your own expectations, then checking how that lines up with today’s US$70.89 share price.
