ISPR operates as a real estate investment trust (REIT) focused on acquiring and leasing properties to state-licensed cannabis operators. While financial ratios meet Shariah screening thresholds across AAOIFI, MSCI, and S&P standards, the core business activity involving the facilitation of cannabis production and distribution—considered haram under Islamic principles—renders the company non-compliant. No inclusion in major Shariah indices confirms this status. Investors should note the high qualitative risk despite strong quantitative metrics. Purification is required for incidental non-compliant income, but the business model disqualifies overall investment.
