Quarterhill is a diversified investment holding company actively engaged in acquiring technology-driven businesses across several sectors, primarily focusing on intelligent transportation systems and intellectual property licensing.

Notable features of Quarterhill's portfolio include operations in sectors such as automotive electronics, transportation infrastructure, and wireless communications, reflecting its broad industry impacts. Before any of that matters to a Muslim investor, one question comes first: is Quarterhill stock Halal?
Is Quarterhill Shariah compliant?
No. In the October 2026 screening Quarterhill (QTRH) does not pass AAOIFI screening: it fails the interest-bearing debt screen. The Shariah case on a technology company like Quarterhill is rarely about the product. What AAOIFI Shariah Standard No. 21 examines is the money around the product: cash parked in instruments that earn Riba, borrowing measured against a market capitalisation that moves daily, and any incidental income from sources Islam prohibits, which must stay below 5% of revenue.
Does Quarterhill pass the business activity test?
The activity screen is only part of the picture this month: Quarterhill currently fails the interest-bearing debt screen, so the overall verdict is not compliant regardless of the business itself. The watch item for technology names is incidental: cash returns and platform content can carry impermissible elements, which AAOIFI tolerates only below the thresholds.
Is Quarterhill's income Halal?
Yes, within AAOIFI's tolerance. Quarterhill's income from non-permissible sources stays below 5% of revenue in the October 2026 screening.
Does Quarterhill 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 CA$415M (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 Quarterhill?
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.
