The Short Answer
Allegro MicroSystems stock (ALGM) is generally considered halal by most Islamic scholars and Sharia screening criteria — the semiconductor business is permissible — though investors should verify the company's term debt against the 33% threshold.
Designing and selling sensor and power semiconductors is a permissible technology activity at the activity level, with strong alignment to vehicle electrification and energy efficiency. The primary consideration is the financial screen: Allegro carries some term debt, so the debt-to-market-cap ratio should be checked at the time of investment.
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)
Allegro's Business Activity
Allegro designs analog and mixed-signal semiconductors, including:
- Magnetic sensors: Position, speed, and current sensing for vehicles and industry
- Power management: Regulators and motor-driver chips for electrified systems
- ADAS and clean-energy: Components for driver assistance and energy equipment
Designing and selling these semiconductors is permissible at the activity level — supporting electrification, safety, and energy efficiency.
Concerns to Be Aware Of
1. Term-Debt Leverage
Allegro carries interest-bearing term debt. Verify the debt-to-market-cap ratio against the 33% Sharia threshold at the time of investment — this is the primary screening consideration. Term loans are interest-bearing instruments.
2. Interest Income on Cash
Interest income from the company's cash balance should be checked against the 5% interest-income-to-revenue threshold, and the relevant portion of any returns purified.
3. Automotive Cyclicality
As an automotive-exposed semiconductor company, Allegro's revenue and margins can be cyclical and sensitive to vehicle-production swings. This is a business consideration rather than a Sharia screen concern.

Bottom Line
Allegro MicroSystems (ALGM) is generally halal with purification for Muslim investors, subject to verifying the debt ratio at the time of investment.
