For Muslim investors, though, the most pressing question is simpler: is Allison Transmission a Halal investment?

Is Allison Transmission Shariah compliant?

No. In the October 2026 screening Allison Transmission (ALSN) does not pass AAOIFI screening: it fails the interest-bearing debt screen. For consumer companies like Allison Transmission, the products are rarely the problem; clothing, cars, travel and home goods are permissible. The exposure is usually financing: stores, inventory and expansion are often funded with borrowing, 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 October 2026 screening.

Does Allison Transmission meet AAOIFI's debt and investment ratio requirements?

Not in full. Interest bearing debt currently exceeds the 30% cap, measured against a market capitalisation of $9.35B (market data as of 1 October 2026), 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.

Why do other halal screeners show a different verdict for Allison Transmission?

Screeners can disagree without either being wrong. AAOIFI Shariah Standard No. 21, which Tabadulat applies, measures interest bearing debt and investments against market capitalisation with a 30% ceiling. MSCI and FTSE measure them against total assets with a 33% ceiling, and S&P and Dow Jones Islamic use a multi year average of market capitalisation. Data dates differ too, because each provider reads filings and prices on its own schedule. The same company can therefore pass one standard and fail another in the same month. Tabadulat publishes one answer, the AAOIFI result as of October 2026, and re-screens it every month.
