ASTS Director Buys $619K as AT&T Backs Satellite
NEW YORK, September 8 —
AST SpaceMobile, Inc. (ASTS) carries a $25 billion market cap on $0.12 billion in trailing revenue, a ratio that implies the BlueBird satellite constellation must become an entirely new tier of global wireless infrastructure. Director Adriana Cisneros made that bet explicit, spending $619,200 on open-market purchases last week as AT&T publicly committed the service will launch next year.
- Four consecutive EPS misses; most recent actual $-0.77 vs estimate $-0.332 (-132.6% surprise); free cash flow negative $1.80 billion trailing.
- 19.2% of the float is short; market cap $25.02 billion on $0.12 billion trailing revenue.
- Berenberg initiated with a buy; analyst consensus target $79.61 vs current price $64.29; FCC cleared 800 MHz for direct-to-device.
What the Carrier Call Changes
The FCC's decision to open 800 MHz spectrum for direct phone-to-satellite connectivity removes a key regulatory ceiling for AST SpaceMobile's BlueBird constellation, built to deliver broadband to standard unmodified smartphones without extra hardware. AT&T's public statement that the offering will "come to fruition" next year is more than partner diplomacy: it names a commercial timeline, and carrier commitments of that specificity are rare. Berenberg's buy initiation, reported by Barron's, added analyst credibility to that signal. The stock has already gained roughly 16-fold over the past three years; the open question is whether these catalysts justify holding at the current multiple.
The Burn Rate the Short Sellers Are Counting On
Four consecutive EPS misses, each wider than the last, anchor the bear case: the most recent landed at -132.6% (actual $-0.77 vs estimate $-0.332), following a -232.6% gap the quarter before. Trailing free cash flow ran to negative $1.80 billion, and the balance sheet carries $2.29 billion in cash against $2.99 billion in total debt. A July 2026 8-K filing disclosed a new debt obligation and unregistered equity issuance, showing the company is still raising capital from markets to fund construction. Run the stock through a DCF calculator at conservative growth assumptions and the current valuation demands a commercial timeline the financials have not yet earned.

The Insider Signal Worth Parsing
Director Cisneros's open-market purchases of 10,822 shares at $57.00, $58.87 on August 31, totaling $619,200, came roughly two weeks after the COO, CFO, and President each had shares withheld for mandatory RSU-vesting taxes at $70.98, $12 to $14 per share above where Cisneros chose to buy. Those withholdings were compulsory, not discretionary, per Form 4 filings, which makes the timing informative rather than contradictory. The next quarterly report is the real checkpoint: whether revenue accelerates and whether the EPS streak breaks, since a fifth consecutive miss would test the credibility of AT&T's next-year pledge.
