The Short Answer
AST SpaceMobile stock (ASTS) is doubtful under Sharia screening. Building space-based cellular broadband is a permissible activity, but AST is a development-stage, largely pre-revenue company that funds its satellite build-out with convertible notes and other interest-bearing debt, which can push the debt-to-market-cap ratio past the 33% threshold.

Business-activity disclosure
AST SpaceMobile is developing space-based cellular broadband infrastructure and carrier partnerships. Satellite telecommunications is generally permissible, but the filing does not classify every future government application, customer end use or partnership into a universal prohibited-revenue numerator.
Limitation: The company is development-stage and largely pre-commercial; the filing does not provide a universal prohibited-activity numerator for future services, government applications or customer end uses.
Purification
AST SpaceMobile discloses $26.998 million of interest income, but ZakatInvest does not prescribe a scholar-approved purification percentage; the development-stage revenue base also makes the ratio unusually volatile.
Inputs, assumptions and primary sources
- Amounts are USD millions from AST SpaceMobile's March 31, 2026 Form 10-Q.
- Interest-bearing debt is current debt of $8.236 million plus noncurrent debt of $2,963.296 million; convertible notes and other debt are included, while operating lease liabilities are excluded.
- Cash and cash equivalents are $3,029.591 million and short-term investments are $2.800 million; restricted cash is excluded from the liquidity numerator.
- Accounts receivable of $27.453 million plus a $18.481 million related-party notes-and-loans receivable are included as receivables; first-quarter revenue is $14.735 million.
- The filing separately discloses $26.998 million of interest income; the net interest-income/expense line is not used as the gross-income numerator.
- Satellite telecommunications and carrier connectivity are generally permissible, while future government applications, counterparties and end uses remain qualitative.
This is a reproducible financial screen, not a fatwa. A failed total-assets screen can coexist with a pass under a market-cap methodology. ZakatInvest keeps the qualitative assessment separate so numerical thresholds do not erase material context.
The business activity itself is fine. The verdict hinges on the financial screen — and the reliance on conventional, riba-based financing means the debt screen can strain or fail depending on the quarter.
Sharia Screening Methodology
Islamic scholars use several criteria to screen stocks:
- Business activity screen: Is the company's primary business halal?
- Debt ratio: Total debt / market cap must be under 33%
- Interest income: Interest income / total revenue must be under 5%
- Haram revenue: Revenue from haram sources must be under 5%
- Receivables ratio: Total receivables / total assets must be under 49–70% (varies by board)
AST SpaceMobile's Business Activity
AST SpaceMobile is building a satellite constellation designed to connect ordinary smartphones directly to space, providing cellular broadband in partnership with mobile network operators. Its activity is:
- Satellite telecommunications: Space-based cellular broadband infrastructure
- Carrier partnerships: Revenue-sharing with mobile operators (largely future)
Satellite telecommunications is a permissible activity with no haram business line — the issue is purely financial.
Why ASTS Is Doubtful
1. Debt Ratio — The Decisive Concern
AST funds its expensive satellite build-out with convertible notes and other interest-bearing debt. Depending on the period, the debt-to-market-cap ratio can strain or exceed the 33% Sharia threshold, which is the primary reason ASTS is flagged as doubtful.
2. Pre-Revenue, Cash-Burning Stage
As a largely pre-revenue development-stage company, AST's ratios are volatile and must be re-screened against the latest filings. A clean pass cannot be assumed from quarter to quarter.
3. Convertible, Interest-Based Financing
Convertible notes are conventional riba-based instruments. Investors who object to such financing should weigh this regardless of where the ratio sits, and any interest income on raised capital should be checked and purified.
Current quantitative Sharia screen
AST SpaceMobile's Form 10-Q for the period ended March 31, 2026 (figures in USD millions) shows:
- Debt / total assets: 49.11% (USD 2,971.532m / USD 6,051.141m) — above the 33.33% asset-based limit.
- Cash + interest-bearing securities / total assets: 50.11% (USD 3,032.391m / USD 6,051.141m).
- Receivables + cash / total assets: 50.83% (USD 3,075.525m / USD 6,051.141m).
- Disclosed interest income / revenue: 183.22% (USD 26.998m / USD 14.735m), reflecting a pre-revenue treasury-heavy period; treatment is methodology-dependent.
Methodology interpretation
Satellite telecommunications is qualitatively permissible, but the current filing-based asset screen fails because convertible debt is 49.11% of assets. ASTS is still development-stage, so investors should re-screen each filing; this analysis is not an official certification by a screening provider.
Bottom Line
AST SpaceMobile (ASTS) is doubtful for Muslim investors. The satellite-telecom business is clearly permissible, but the decisive issue is the convertible and interest-bearing debt used to fund the satellite build-out, plus the pre-revenue, cash-burning stage that makes the ratios volatile. Cautious investors should avoid ASTS until the balance sheet stabilizes; others should verify the current debt ratio carefully and purify any interest income.
For Muslim investors seeking permissible communications and space exposure, compare ASTS with cleaner-balance-sheet peers like Intuitive Machines (LUNR).
