AST SpaceMobile, Inc. (ASTS) Cash Flow Statement

The gap between net income and operating cash flow is largely attributable to $63.5M in stock-based compensation and $20.7M in depreciation, which are non-cash charges. This suggests that the reported net loss overstates the actual cash burn, but the underlying cash consumption remains substantial. Investors should monitor whether the increasing SBC, which has grown from $4.9M in 2024Q1 to $63.5M in 2026Q2, indicates a reliance on equity-based compensation to preserve cash.

The trajectory of free cash flow is sharply negative, reflecting the heavy capital expenditure required for satellite manufacturing and launches. The FCF margin has remained deeply negative, and the absolute burn has increased more than seven-fold over the period, indicating an acceleration in investment ahead of commercial scale. This suggests that the company is in a pre-revenue phase where cash consumption is expected to continue until the constellation is operational.

The sharp increase in capex, particularly in the most recent quarter, indicates a shift from development to production and launch activities. The capital intensity relative to revenue is extreme, though revenue is still minimal, suggesting that the company is investing heavily in its satellite fleet. This capex is likely growth-oriented, as it is aimed at building the constellation that will generate future service revenue, but it also implies a prolonged period of negative free cash flow.

The working capital fluctuations are likely tied to the timing of milestone-based revenue from NRE contracts and government services, as well as payments to suppliers. The positive change in 2025Q4 may indicate a large cash collection, while the negative change in 2026Q2 suggests an outflow, possibly for inventory or prepayments. This volatility underscores the lumpy nature of the company's current revenue streams and the need to monitor cash conversion cycles as the business transitions to recurring revenue.

The absence of capital returns is consistent with a pre-commercial company that is reinvesting all available cash into its satellite network. The company's capital deployment strategy appears focused on growth, with capex exceeding operating cash outflows by a wide margin. This suggests that external financing will be required to sustain the build-out, and investors should monitor the balance sheet for potential dilution.

The divergence between cumulative net income and operating cash flow is substantial, with net losses exceeding cash outflows by nearly three times. This gap is primarily due to non-cash charges such as stock-based compensation and depreciation, which have grown as the company scales. While this suggests that the cash burn is less severe than the income statement implies, the absolute cash consumption is still significant and will require continued funding.
