The tell is the capex line. AST SpaceMobile's filings show capital expenditures of $1,064.7 million in fiscal 2025 — a roughly six-fold jump from $174.1 million in 2024. That is the financial signature of a company moving from prototypes to a deployed constellation: the BlueBird satellites and the manufacturing to build them are showing up as property-and-equipment spend, not as expense.
Crucially, the cash kept pace. ASTS ended 2025 with $2,335.7 million in cash and equivalents, up from $565.0 million a year earlier, and the Q1 2026 Form 10-Q reports $3,029.6 million as of March 31, 2026. A company that lifts capex six-fold and simultaneously triples its cash balance is doing one thing: financing the build ahead of the spend, almost entirely from raised capital rather than operations.
That is the structure to read plainly. For a pre-revenue direct-to-cell operator, capex is the business plan made visible, and every dollar of it has to be funded before service scales. The Q3 2025 Form 10-Q earlier in the year showed the same trajectory — cash at $1.20 billion in September against nine-month capex of $669 million. The cushion is large, but it exists to be spent on satellites.
The capital-markets read: ASTS has bought itself a long runway, but the runway is denominated in launches and manufacturing, not quarters of profit. The figures to track are capex against the cash cushion and whether the next raise arrives before the cushion thins — because for this kind of constellation, the build always finds the cash.
