Is Onto Innovation Stock (ONTO) Halal? A Complete Analysis

The Short Answer

Onto Innovation (ONTO) has a qualitative business verdict that is HALAL and passes the known filing-based financial ratios, but the overall screen remains incomplete. Onto develops process-control tools, metrology-and-inspection systems, and advanced-packaging-lithography systems for semiconductor manufacturing.

Semiconductor-metrology, inspection, lithography, and process-control-software manufacturing are generally permissible at the activity level. The March 31, 2026 filing reports no drawn debt, and the known asset-based ratios pass; downstream activity revenue is not separately quantified.

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)

Onto's Business Activity

Onto Innovation, formed from the merger of Nanometrics and Rudolph Technologies, develops and manufactures:

• Metrology & inspection: Optical-metrology, defect-inspection, and wafer-and-package inspection systems
• Lithography: Advanced-packaging-lithography systems
• Software: Process-control software that integrates and analyzes fab process-control data

These are general-purpose semiconductor-capital-equipment businesses — manufacturing the tools that measure, inspect, and control semiconductor production. This is permissible at the activity level.

Concerns to Be Aware Of

1. Customer Concentration & Cyclicality

Revenue is exposed to the semiconductor-capital-equipment cycle and can be concentrated among a limited number of large fab-and-packaging customers. This is a business-cycle and customer-concentration consideration rather than a Sharia screen concern.

2. Export Controls & Geopolitics

Export-control and geopolitical restrictions on semiconductor equipment can affect specific end-markets. This is a regulatory-and-business consideration rather than a Sharia screen concern.

3. Minor Interest Income

The filing reports $5.102 million of net interest income, or 1.75% of quarterly revenue. ZakatInvest shows that disclosed line without prescribing a fixed purification percentage.

Filing-Based Ratios (March 31, 2026)

Using the latest Onto Innovation Form 10-Q (USD millions):

• Debt / total assets: 0.00%
• Cash + securities / total assets: 27.30%
• Receivables + cash / total assets: 23.32%
• Disclosed net interest income / revenue: 1.75%

Methodology Interpretation

These are ZakatInvest calculations from the cited filing, not claims of current index membership or an official scholar ruling:

• FTSE-style: Known financial ratios pass; business activity remains qualitative.
• MSCI-style: Known financial ratios pass; this is not an index-membership claim.
• Malaysia-style: Known debt and liquidity ratios pass; this is not an official classification.

Bottom Line

Onto Innovation (ONTO) has a generally permissible semiconductor-equipment business and passes the known filing-based financial ratios. Because no universal prohibited-revenue numerator is disclosed, the overall result remains incomplete rather than a universal halal certification; investors should apply their preferred methodology and review future filings.

For Muslim investors seeking semiconductor-equipment exposure, ONTO sits alongside other halal-screened names like Entegris (ENTG) and Advanced Energy (AEIS).
