Business-activity disclosure

Acuity manufactures lighting, lighting controls and intelligent-building products. General-purpose building technology is generally permissible, while commercial, institutional and infrastructure end markets remain qualitative.

Limitation: The filing does not provide a universal prohibited-revenue numerator across the product and end-market mix.

Purification

A small disclosed investment-interest amount is reported, but no universal prohibited-revenue numerator or scholar-specific purification instruction is provided.

Inputs, assumptions and primary sources
  • Amounts are USD millions from Acuity's May 31, 2026 Form 10-Q for the nine months ended that date.
  • Conservative debt combines $697.3 million noncurrent debt with $107 million operating-lease liabilities.
  • Cash is $411.9 million, net accounts receivable is $610.9 million and the reported period revenue is $1,198 million.
  • Disclosed investment interest income is $1.7 million, or 0.14% of the reported revenue period.
  • Lighting, controls and intelligent-spaces products are generally permissible, while end-market allocation remains qualitative.

This is a reproducible financial screen, not a fatwa. A failed total-assets screen can coexist with a pass under a market-cap methodology. ZakatInvest keeps the qualitative assessment separate so numerical thresholds do not erase material context.

Lighting manufacturing, lighting-controls manufacturing, and intelligent-building-management-systems manufacturing are generally permissible at the activity level under standard Sharia methodology. Known asset ratios pass, while the current filing-based result remains incomplete for income and prohibited-revenue allocation.

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)

Acuity's Business Activity

Acuity operates through two reporting segments:

  • Acuity Brands Lighting and Lighting Controls (ABL): Luminaires, lighting-controls, and components for commercial, industrial, institutional, and residential applications under brands including Lithonia Lighting, Holophane, and Juno
  • Intelligent Spaces Group (AIS): Building-management-systems, controls, and spatial-data-and-location-aware technologies

Manufacturing physical lighting and building-management products is a permissible general-purpose building-products-and-technology activity.

Concerns to Be Aware Of

1. Minor Interest Income

Minor interest income on cash and short-term investment balances means purification of a small portion of dividends may be advisable.

2. Leverage Profile

The debt-to-market-cap ratio should be re-verified against the 33% Sharia threshold at the time of investment given Acuity's acquisition activity (including the QSC intelligent-spaces acquisition) and share-repurchase program. It generally sits below the threshold.

3. Cyclicality

Exposure to non-residential-construction and renovation cycles, along with raw-material (steel, aluminum, electronic-components) and freight input-cost volatility, can drive earnings volatility. These are business-cycle considerations rather than Sharia screen concerns.

Filing-Based Ratios (May 31, 2026)

Based on Acuity's latest Form 10-Q:

  • Debt / Total Assets: 17.35% — below examined limits ✅
  • Liquidity / Total Assets: 8.89% ✅
  • Receivables + Cash / Total Assets: 22.06% ✅
  • Disclosed Investment Interest / Revenue: 0.14% ⚠️
  • Prohibited-Product Revenue: No universal numerator disclosed — qualitative review required ⚠️

Methodology Interpretation

The current filing-based asset ratios pass the examined FTSE, MSCI and Malaysia-style limits. The building-technology activity remains generally permissible, but investment-income and end-market treatment require review.

  • Core activity: Lighting, controls and intelligent-building products
  • Quantitative status: Known asset ratios pass; data remains incomplete
  • Scholar review: Confirm income and end-market treatment

Bottom Line

Acuity Brands, Inc. (AYI) has a generally permissible core activity and passing known asset ratios, but the current filing-based result is incomplete because the filing does not provide a universal prohibited-revenue numerator.

For Muslim investors seeking building-products-and-technology exposure, AYI sits alongside other halal-screened names like Hubbell (HUBB) and nVent Electric (NVT).
