Is MPLX LP (MPLX) Halal?

FAIL

MPLX LP · NYSE: MPLX · Energy

The short answer

No - MPLX LP (MPLX) fails this Shariah stock screen at the debt gate. MPLX, the Findlay, Ohio-based master limited partnership sponsored by Marathon Petroleum, operates midstream energy infrastructure (crude/product pipelines, marine, terminals, storage, gas gathering/processing, NGL fractionation) - its business activity is clean. But interest-bearing debt of $25,640M is about 43.86% of its ~$58.46B market cap (October 2, 2026), above the ~33% ceiling. Interest income is $68M (FY2025 10-K Note 18), about 0.52% of $12,998M revenue - under the 5% ceiling. Third-party screeners agree with the non-compliant outcome: Zoya marks MPLX not Shariah-compliant, Musaffa marks it Not Halal (AAOIFI, October 2026), and ShariaPortfolio says it 'is not Shariah Compliant because it fails the financial ratios.' This is a factual screen, not a religious ruling - consult a qualified scholar for personal rulings.
