What You Should Know

Carlisle Companies is a US specialty-building-products manufacturer organized into two reporting segments after a multi-year portfolio repositioning: Carlisle Construction Materials (single-ply commercial roofing membranes, polyurethane spray-foam and rigid-board insulation, waterproofing, and metal roofing under brands including Carlisle SynTec, Henry, Versico, and Hunter Panels) and Carlisle Weatherproofing Technologies (waterproofing membranes, sealants, and air-and-vapor barriers for residential and commercial building envelopes). The customer base consists of commercial roofing contractors, residential builders, and building-products distributors across North America. Specialty building-envelope and roofing products are unambiguously permissible at the activity level. Carlisle has divested its industrial-products and interconnect-technology segments to focus on building products. The balance sheet has been used for sizable acquisitions (notably the 2023 Henry Company acquisition), and the debt-to-market-cap ratio has at times sat near the 33% Sharia threshold, but Carlisle has been deleveraging from strong free cash flow. The qualitative screen passes cleanly across major Sharia advisory boards. Muslim investors should verify the current debt-to-market-cap ratio at their preferred screening platform.
