Is Acuity (AYI) stock Halal?

Acuity is a leading provider of lighting solutions and building management systems. The company designs, produces, and distributes innovative lighting products for various settings, including commercial, institutional, industrial, infrastructure, and residential applications. Acuity Brands is known for integrating quality engineering and smart controls into their products, ensuring efficient energy use and enhanced building environments. Before any of that matters to a Muslim investor, one question comes first: is Acuity stock Halal?

Is Acuity Shariah compliant?

Yes. In the October 2026 screening Acuity (AYI) passes AAOIFI Shariah Standard No. 21: the business activity screen and every financial ratio screen hold. For a utility like Acuity, AAOIFI Shariah Standard No. 21 has little quarrel with the service itself; the scrutiny falls on how the infrastructure is financed. Regulated networks are usually built with long term borrowing, which the standard tolerates only below 30% of market capitalisation, a ratio that moves with the share price as well as the debt.

Does Acuity pass the business activity test?

Yes. In the October 2026 screening Acuity holds an overall PASS, which a stock only earns when its core business clears the activity screen. Delivering power or water raises no Shariah objection in itself; the scrutiny belongs to the debt behind the network.

Is Acuity's income Halal?

Yes, within AAOIFI's tolerance. Acuity's income from non-permissible sources stays below 5% of revenue in the October 2026 screening, and the small impure portion is handled through purification: the factor of 99.86% tells holders of AYI what share of each dividend to keep and what remainder to donate to charity. On a dividend yield of around 0.25%, the purification amount is modest but real.

Does Acuity meet AAOIFI's debt and investment ratio requirements?

Yes. Both caps hold this month: interest bearing investments and interest bearing debt each stay below 30% of market capitalisation, measured against a market capitalisation of $9.27B (market data as of 1 October 2026). Because the caps move with the share price, our Shariah Supervisory Board has AYI re-screened every month, and the result above always shows the latest verdict.

Why do other halal screeners show a different verdict for Acuity?

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.

Tabadulat is an ADGM regulated brokerage whose license covers Shari'a Compliant Regulated Activities, as the FSRA permission names them. New to the terminology? Gharar and Maysir, Sukuk, Zakat and purification are all explained in plain English.
