Is BLDR (Builders FirstSource, Inc.) Halal or Haram?

Builders FirstSource, Inc. (BLDR) is a major U.S. supplier of structural building materials and manufactured components. The company provides essential construction products like dimensional lumber, engineered wood, roof trusses, and custom window units to professional homebuilders and contractors. For Muslim investors using HalalStocks.co.uk, BLDR is currently classified as Doubtful. While its core business of supplying physical building materials is completely halal, the stock fails the AAOIFI financial screening criteria due to a significant breach in the debt threshold. The primary concern for Islamic portfolios is the company's debt-to-market cap ratio, which stands at 57.9%, far exceeding the 33% limit. On a positive note, the company maintains very clean revenue streams with 0.00% interest income and holds minimal cash and securities at just 1.9% of its market cap. Since the non-compliance is entirely driven by capital structure rather than haram business activities, Muslim investors should monitor BLDR's balance sheet. If the company pays down its debt or experiences a significant market cap expansion that lowers the ratio below 33%, it could quickly regain shariah-compliant status. Builders FirstSource, Inc. operates in the Industrials sector under the Construction industry and is headquartered in Irving, TX, US. The company is led by CEO Peter Jackson and employs approximately 29,000 people.

BLDR was screened using AAOIFI-based shariah compliance criteria. Four tests are applied: (1) Business Activity — the company's core business must not derive primary income from haram (prohibited) activities such as alcohol, gambling, tobacco, or interest-based finance. (2) Debt-to-Market-Cap — total debt must not exceed 33% of market capitalization. (3) Interest Income — interest income must not exceed 5% of total revenue. (4) Cash & Securities — cash and interest-bearing securities must not exceed 33% of market cap. BLDR passed 3 of these 4 screens.

BLDR was last screened on 2026-04-29. Shariah compliance status can change as companies report new financial data, acquire new businesses, or shift revenue streams. We recommend checking back periodically for the most up-to-date screening results.
