GLW

Corning Incorporated

DOUBTFUL — DATA INCOMPLETEstock

Is GLW Halal?

Permissible specialty-materials manufacturer, but the current filing-based screen is incomplete because end-use activity is not fully quantified.

What You Should Know

Corning Incorporated makes specialty glass, ceramics and optical-fiber products. Its March 31, 2026 Form 10-Q reports assets of $31,253 million, debt of $8,973 million, cash of $1,755 million, accounts receivable of $2,676 million and quarterly revenue of $4,144 million. Debt/assets is 28.71%, liquidity/assets is 5.62%, receivables-plus-cash/assets is 14.18% and disclosed interest income/revenue is 0.22%, below the examined financial limits. A prohibited-activity revenue numerator is not separately disclosed, so the overall result remains incomplete.

⚠️ Concerns

  • Capital-intensive manufacturer carries $8,973 million of debt
  • Display, telecom and automotive end uses require qualitative review
  • Quarterly interest income is $9 million and requires purification analysis
  • Re-screen after the next filing

Business-activity disclosure

Corning makes specialty glass, ceramics, optical fiber and related materials. Materials manufacturing is generally permissible, while customer end uses require separate review.

Limitation: The filing does not provide a reproducible prohibited-revenue numerator across end markets.

Purification

Quarterly interest income is disclosed at $9 million, but no scholar-approved purification percentage is inferred.

Inputs, assumptions and primary sources
  • Amounts are USD millions from Corning's March 31, 2026 Form 10-Q.
  • Debt includes current and long-term debt; separately identified interest-bearing securities were not available, so the input is zero rather than an estimate.
  • Quarterly revenue is $4,144 million and interest income is $9 million.
  • No prohibited-activity revenue numerator is separately disclosed.

This is a reproducible financial screen, not a fatwa. A failed total-assets screen can coexist with a pass under a market-cap methodology. ZakatInvest keeps the qualitative assessment separate so numerical thresholds do not erase material context.
