Business-activity disclosure
Amphenol manufactures connectors, sensors, antennas and interconnect systems. Manufacturing is generally permissible, while aerospace, defense and customer end uses require separate review.
Limitation: The filing does not provide a reproducible prohibited-revenue numerator or a separately stated interest-income line.
Purification
A separate interest-income amount is not available in the extracted filing statement, so no scholar-approved purification percentage is inferred.
Inputs, assumptions and primary sources
- Amounts are USD millions from Amphenol's March 31, 2026 Form 10-Q.
- Debt includes current and long-term debt.
- Quarterly revenue is $7,620.1 million; interest income is not separately disclosed in the extracted statement.
- 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.
Liquidity/assets is 10.88% and receivables-plus-cash/assets is 23.74%; interest income and prohibited-activity revenue are not separately quantified. The debt failure drives the doubtful result.
Sharia Screening Methodology
Islamic scholars use several criteria to screen stocks:
- Business activity screen: Is the company's primary business halal?
- Debt ratio: Total debt / market cap must be under 33%
- Interest income: Interest income / total revenue must be under 5%
- Haram revenue: Revenue from haram sources must be under 5%
- Receivables ratio: Total receivables / total assets must be under 49–70% (varies by board)

Concerns to Be Aware Of
1. Acquisition-Related Debt
Amphenol is a frequent acquirer and funds deals partly with debt. This is the primary screening item.
Action required: Confirm that total debt / market cap stays under the 33% threshold using the latest filings.
2. Aerospace and Defense-Adjacent Work
A portion of Amphenol's revenue comes from aerospace and defense-adjacent programs. Standard screening does not treat this as haram, but stricter investors may want to review the segment mix.
3. Receivables and Minor Interest Income
As a component maker selling to OEMs and distributors, Amphenol carries receivables worth checking against the ratio screen, and a small amount of interest income on cash that should be checked against the 5% threshold and purified.
Action required: Confirm total receivables / total assets against your screening board's threshold (49–70%).
Methodology Interpretation
The debt ratio fails the examined FTSE Yasaar, MSCI and Malaysia asset proxies. This is our filing-based analysis, not a third-party classification.
Bottom Line
Amphenol (APH) is doubtful on the current filing-based screen. Its manufacturing activity is generally permissible, but debt/assets is above the examined limits.
For Muslim investors seeking halal exposure to the connectivity backbone of electronics, APH is a clean, manufacturing-based option.
