JELD-WEN Holding, Inc. (JELD) operates in the building products sector, manufacturing doors and windows, which is generally permissible under Shariah principles. However, severe financial ratio failures, particularly the debt-to-market cap ratio of 303.43%, lead to non-compliance across standards. While income ratios are acceptable, the company is excluded from all major Shariah indices due to leverage issues. Purification is required for non-compliant income, and investors should monitor deleveraging efforts.
