AST SpaceMobile (ASTS) is back in focus after reports that it may join SpaceX in bidding for nationwide 800 MHz spectrum licenses, a move closely tied to its direct to device broadband plans.

The spectrum headlines come on top of a volatile year for AST SpaceMobile, with a 1 day share price return of 5.52%, a 30 day share price gain of 22.15%, a 90 day share price decline of 35.15%, and a year to date share price decline of 17.75%. At the same time, longer term total shareholder returns remain strong, with a 1 year total shareholder return of 45.85% and a very large 3 year total shareholder return, suggesting momentum has shifted recently even as the long term story has rewarded patient holders.

AST SpaceMobile now trades at a sizeable discount to both analyst targets and some intrinsic value estimates after the latest spectrum headlines. Is that a genuine mispricing, or a fair reflection of execution and loss risks?

Most Popular Narrative: 59.6% Undervalued

According to the most followed narrative on AST SpaceMobile, the fair value sits well above the recent close of $68.65, which puts the current discount in sharp focus.

The current numbers show both the promise and the risk. AST reported Q1 2026 revenue of $14.7 million, but that missed some market expectations, and the company posted a loss of $0.66 per share. Management nevertheless reaffirmed 2026 revenue guidance of $150 to $200 million and said it expects revenue to build sequentially through the year.

Curious what has to happen between those early losses and that higher fair value. The narrative leans heavily on steep revenue ramp, richer margins, and a premium future multiple. The exact mix of those assumptions is what really matters.

Result: Fair Value of $170 (UNDERVALUED)

However, this optimistic AST SpaceMobile narrative can quickly be tested if satellite deployment targets slip or major carrier partners are slow to convert agreements into meaningful revenue.

Another View on AST SpaceMobile’s Valuation

The popular AST SpaceMobile narrative leans on a fair value of $170, yet the company trades on a P/B of 10.9x compared with 1.8x for the US Telecom industry and 13.6x for peers. That premium relative to the sector but discount relative to peers raises a simple question: is this paying up for quality or just paying up.
