AST SpaceMobile (ASTS): Revisiting Valuation After BlueBird 6 Launch Optimism and New Commercial Commitments

Simply Wall St

AST SpaceMobile (ASTS) is back in the spotlight after investor interest jumped ahead of its BlueBird 6 launch, a key test of whether the company can turn its space based mobile network into a real commercial business.

See our latest analysis for AST SpaceMobile.

The Christmas Eve BlueBird 6 launch has become the focal point for AST SpaceMobile, with the 1 day share price return of 15.03 percent adding to a 250.46 percent year to date share price return and a massive 1 year total shareholder return of 226.19 percent, suggesting momentum is clearly building as investors reassess the company’s long term rollout and execution risks.

If this kind of speculative momentum has your attention, it might also be worth scanning other high growth tech and satellite names via high growth tech and AI stocks for fresh ideas.

Yet with AST SpaceMobile trading above consensus price targets but still showing a hefty intrinsic discount, the real question is whether this launch fueled rally leaves upside on the table or already incorporates the growth story.

Price to Book of 17.2x, Is it Justified?

AST SpaceMobile trades at a steep premium to peers on a price to book basis, with the last close reflecting a richly valued balance sheet story.

The price to book ratio compares the company’s market value to its net assets, a useful lens for asset heavy, capital intensive telecom and satellite players. For AST SpaceMobile, this multiple signals that investors are paying far more than the accounting value of equity, effectively front loading expectations for future growth, profitability and returns on capital.

That optimism stands out when set against the wider US telecom space, where the average price to book multiple sits near 1.1 times. This highlights how stretched AST SpaceMobile’s 17.2 times figure appears. Against more direct peers, the stock still screens expensive versus a 6.3 times peer average, which underlines that the current valuation assumes the company will grow into a far more profitable, higher return profile than its sector.

Result: Price to Book of 17.2x (OVERVALUED)

However, execution risk around BlueBird deployment and ongoing cash burn, given negative net income, could quickly reverse sentiment if launches or partnerships disappoint.
