Is Allison Transmission (ALSN) stock Halal?
Under AAOIFI Shariah Standard No. 21, a Halal stock keeps non-permissible income below 5% of revenue and interest-bearing debt and investments each below 30% of market capitalisation. Allison Transmission Holdings, Inc. (ALSN) does not meet the threshold for the interest-bearing debt screen as of September 2026, so it is not Shariah compliant.
Allison Transmission is a prominent global manufacturer and supplier of fully automatic transmissions and propulsion systems. The company primarily serves the commercial vehicle and defense sectors, delivering solutions that enhance the performance, efficiency, and reliability of heavy-duty vehicles. Known for its durable and high-performance products, Allison Transmission caters to a wide range of industries, including construction, emergency response, mining, and public transportation, amplifying its impact across the transportation infrastructure market. For Muslim investors, though, the most pressing question is simpler: is Allison Transmission a Halal investment?
Is Allison Transmission Shariah compliant?
For industrial companies like Allison Transmission, the product is rarely the problem; aircraft, vehicles and machinery are permissible. The exposure is leverage: fleets and factories are financed, and the 30% cap that AAOIFI Shariah Standard No. 21 places on interest bearing debt is the screen that decides most verdicts in this sector.
Does Allison Transmission pass the business activity test?
The activity screen is only part of the picture this month: Allison Transmission currently fails the interest-bearing debt screen, so the overall verdict is not compliant regardless of the business itself. The activity itself raises no Shariah objection; the scrutiny belongs to the financing.
Is Allison Transmission's income Halal?
Yes, within AAOIFI's tolerance. Allison Transmission's income from non-permissible sources stays below 5% of revenue in the September 2026 screening.
Does Allison Transmission meet AAOIFI's debt and investment ratio requirements?
Not in full. Interest bearing debt currently exceeds the 30% cap, while the other ratio stays within it. One breach is enough to fail the screening; the ratios are reassessed monthly under our Shariah Supervisory Board.
