Is RPM International Stock (RPM) Halal? A Complete Analysis

The Short Answer

RPM International stock (RPM) is generally considered halal by most Islamic scholars and Sharia screening criteria. RPM is a manufacturer and marketer of specialty coatings, sealants, building materials, and related products for industrial and consumer markets.

Specialty-coatings manufacturing, sealants-and-adhesives manufacturing, and building-and-construction-products manufacturing are unambiguously permissible at the activity level under standard Sharia methodology. The primary screening consideration is verifying leverage against the 33% threshold.

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)

RPM's Business Activity

RPM operates through reporting segments including Construction Products Group, Performance Coatings Group, Consumer Group, and Specialty Products Group. Its well-known brands include:

• Rust-Oleum: Consumer rust-prevention and home-improvement coatings
• DAP: Sealants, caulks, and adhesives
• Tremco & Carboline: Protective-and-industrial coatings and roofing-and-waterproofing systems
• Zinsser: Primers and specialty coatings

Manufacturing physical specialty chemicals, coatings, and construction products is a permissible industrial activity.

Concerns to Be Aware Of

1. Leverage Profile

This is the primary Sharia-screening consideration. RPM carries moderate leverage from its acquisitive growth strategy and a long-standing dividend program (it is a dividend-aristocrat), so the debt-to-market-cap ratio should be verified against the 33% Sharia threshold at the time of investment.

2. Minor Interest Income

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

3. Input-Cost Volatility

Raw-material (resin, solvent, pigment, and other petrochemical-derivative feedstock) input-cost volatility, along with construction-and-consumer-demand cycles, can drive earnings volatility. These are business-cycle considerations rather than Sharia screen concerns.

Bottom Line
