Is Joby Aviation Stock (JOBY) Halal? Current Quantitative Sharia Screen

The Short Answer

Joby Aviation (JOBY) is doubtful under this screen. Civil aviation and clean transportation are broadly permissible activities, but the latest filing-backed liquidity proxy is 84.24% of assets and the conservative investment-income proxy is 73.35% of quarterly revenue. The filing also does not isolate government-flight or defense-related revenue into a universal prohibited-revenue numerator. This is a screening judgment, not a fatwa or personalized investment advice.

This is a reproducible ZakatInvest calculation from Joby Aviation's first-quarter 2026 Form 10-Q for the period ended March 31, 2026. It separates reported financial inputs from school-dependent qualitative conclusions and does not claim an official third-party index classification.

Current Quantitative Screen (March 31, 2026)

• Debt / assets: 23.95% — $701.056 million of long-term debt against $2,927.654 million of total assets
• Cash plus identifiable interest-bearing securities / assets: 84.24% — $874.524 million of cash plus $1,591.665 million of short-term investments
• Receivables + cash / assets: 30.26% — $11.498 million of accounts and other receivables plus cash
• Quarterly revenue: $24.246 million — $21.754 million passenger revenue and $2.492 million other revenue
• Interest and other income, net: $17.784 million, or 73.35% of quarterly revenue; this is a conservative upper bound, not a pure-interest-only figure
• Market-cap denominator methods: Not calculated because a licensed, reproducible historical market-cap series is not stored

Debt/assets and receivables plus cash are below the examined limits, but identifiable liquidity fails all examined asset-based methods and the conservative combined-income proxy exceeds the FTSE income limit. The result is therefore a financial-screen failure even though Joby is still early in commercial operations.

Joby's Business Activity

Joby is developing a clean, quiet, fully electric vertical takeoff and landing aircraft for passenger air-taxi service. Its current operations also include passenger flights, engineering, rental income and government flight services. The company has partnerships and commercial relationships involving manufacturing, booking, launch planning and aviation infrastructure.

Civil aviation and clean transportation are broadly permissible. The Form 10-Q reports passenger revenue separately, while other revenue includes customer-directed flights and on-base operations for U.S. Department of Defense agencies, engineering services and rental income. It does not provide a reproducible percentage for defense, dual-use or downstream end-use activity, so the business screen remains incomplete rather than being assigned an invented prohibited-revenue figure.

Why JOBY Is Doubtful — The Financial Screen

1. Short-term investments dominate the balance sheet

At March 31, 2026, Joby reported $874.524 million of cash and $1,591.665 million of short-term investments against $2,927.654 million of assets. The combined 84.24% liquidity proxy is above the examined FTSE Yasaar, MSCI and Malaysia SAC asset-based limits. The filing describes money-market funds, term deposits, asset-backed securities, government debt securities and corporate debt securities, so instrument treatment should be reviewed under the investor's chosen methodology.

2. The income line is unusually large relative to current revenue

Joby reported $17.784 million of interest and other income, net against $24.246 million of quarterly revenue. The filing says interest income consists primarily of interest earned on cash and investments, but the line is not a pure-interest-only numerator; ZakatInvest uses it as a conservative upper bound and does not turn it into a fixed purification prescription.

3. New convertible debt and a mortgage loan changed the profile

Joby issued $690 million principal amount of 0.75% convertible senior notes and entered a $30.75 million mortgage loan during the quarter. Debt/assets remains below the examined limits, but the new financing means the older equity-funded description is stale and should not be carried forward without a filing date.

4. Defense and government services remain qualitative

Government-flight services and Department of Defense work may be viewed as dual-use transportation rather than weapons activity, while stricter advisers may apply a different end-use analysis. The filing does not quantify those revenues separately enough to resolve every school-specific view.

How to Read the Result

JOBY has a broadly permissible civil-aviation business, but the current asset-based financial screen fails because identifiable liquidity is 84.24% of assets and the conservative income proxy is unusually high relative to revenue. Government-flight and defense-related revenue remains incomplete. The result is doubtful—not an official index label—and can change as Joby converts investments into aircraft infrastructure, generates more passenger revenue, repays debt or reports a clearer revenue mix.

Bottom Line

Joby Aviation (JOBY) is currently doubtful for Muslim investors under the retained quantitative and qualitative framework. Civil eVTOL transportation is broadly permissible, but reported investment liquidity and the conservative investment-income proxy fail the examined financial screens, while government-flight revenue remains disclosure-limited. Investors should consult a qualified Sharia adviser for a school-specific conclusion.
