AST has $3.5B in
the bank — and is
spending it fast.
For a pre-profit company, the only question that matters is how long the cash lasts.

✦ The bottom line
AST holds about $3.5 billion in cash — a genuine war chest. But it's spending over $1 billion a year building satellites and lost $342M last year. The clock is the whole story.

How long the money lasts
For a company that spends more than it earns, 'cash runway' is the number of years it can keep going before it needs more money. Lots of cash buys time; heavy spending burns it. The gap between them is everything.
Wall Street calls this
Cash runway
AST's bet only works if it can launch a working network *before* the cash runs out — or raise more on good terms.

$3.5
B
About $3.5B in cash, equivalents and restricted cash — among the strongest balance sheets of any pre-profit company. It bought this time by selling stock and debt.
$3.5 billion sounds like plenty — until you see the spending. Each satellite costs tens of millions to build and launch, and AST is building dozens. So the cash flows out fast, mostly into hardware. How fast? Look at what it spent on satellites and equipment last year.

B
Roughly $1.1B spent on satellites and equipment in 2025 alone — plus a $342M net loss. The constellation is enormously expensive to build.

Put the two together — about $3.5B in the bank, more than $1B a year going out the door — and you get a runway measured in just a few years. That's enough to launch a meaningful chunk of the constellation, but probably not the whole 100-plus-satellite network. Which means AST will almost certainly have to raise more money before it's done.

Watch
A $3.5B war chest, but burning $1B+ a year — the runway, and the next raise, are the whole question.
