Leslie's, Inc. (LESL) operates in the pool and spa retail sector, offering maintenance products and services. This report evaluates its Shariah compliance across financial ratios, business activities, ESG factors, and index inclusions. Key concerns include an exceptionally high debt-to-market cap ratio of 894.55%, exceeding all standard thresholds, and an interest income ratio of 19.87%, requiring purification. While core business activities are permissible, financial metrics lead to non-compliance under major standards. No inclusion in Shariah indices confirms the overall status.
