Is Leidos Stock (LDOS) Halal? A Complete Analysis

The Short Answer

Leidos stock (LDOS) is generally considered halal by most Islamic scholars and Sharia screening criteria, with caveats on defense end-market concentration. LDOS is a US technology-services company serving primarily US government customers across Defense, Civilian, Health, and Intelligence reporting segments. The services include software development, systems integration, cybersecurity, data analytics, and engineering services.

The technology-services business is permissible at the activity level — Leidos provides general-purpose IT, cyber, software, and engineering services rather than manufacturing weapons systems or munitions. Most Sharia advisory boards classify defense IT-services contractors as halal on the qualitative screen because the services are general-purpose rather than weapons production, but some stricter boards apply defense-end-market screens that exclude government contractors with significant defense revenue.

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)

Leidos's Business Activity

Leidos operates across four reporting segments:

• Defense Solutions: Combat support, mission systems, cyber operations, command-and-control systems, training and simulation, sensors
• Civil: Border security (CBP), public health, Federal Aviation Administration air-traffic-control modernization, transportation security, energy and environment
• Health: Defense Health Agency, Veterans Affairs IT modernization, electronic health records integration
• Intelligence: Mission-software, geospatial intelligence, signals intelligence, agile-software-development services for the intelligence community

Technology-services is permissible at the activity level — the work is IT, software, cyber, and engineering services rather than weapons production.

Concerns to Be Aware Of

1. Defense End-Market Concentration

A significant share of revenue comes from Department of Defense customers. Most Sharia advisory boards classify defense IT-services contractors as halal because the services are general-purpose rather than weapons production. Some stricter boards apply defense-end-market screens that exclude government contractors with significant defense revenue. Muslim investors should verify the qualitative screen against their preferred Sharia advisory board's methodology.

2. Intelligence-Community Customers

Leidos has a large intelligence-community customer base. Some Sharia advisory boards apply intelligence-end-market screens; others classify mission-software and analytics services as general-purpose IT.

3. Acquisition-Financing Debt

Leidos carries term-loan debt from prior acquisitions (notably the 2016 IS&GS deal with Lockheed Martin and the 2020 Dynetics and L3 acquisitions). The debt-to-market-cap ratio has historically been near or below the 33% Sharia threshold; verify current ratio at your preferred screening platform.

4. Minor Interest Income

LDOS earns modest interest income on cash reserves. Scholars require purification of approximately 1–2% of dividends.

Financial Ratios (2025)

Based on Leidos's most recent financial statements:

• Total Debt / Market Cap: Near or below 33% — verify current ratio ⚠️
• Interest Income / Revenue: Under 5% ✅
• Haram Revenue: Negligible at the activity-level; qualitative-screen view varies on defense end markets ⚠️
• Receivables Ratio: Within limits ✅

Verdict from Major Screening Agencies

Leidos stock screens as compliant or doubtful, depending on Sharia advisory board methodology on defense end markets:

• Zoya App — Often Compliant when ratios pass and the qualitative screen treats defense IT-services as general-purpose ⚠️
• MSCI Islamic criteria — Methodology view on defense end markets varies ⚠️
• Strict Sharia advisory boards — Some classify as failing the defense-end-market qualitative screen ❌
• Most major Sharia advisory boards — Approved as general-purpose IT services ✅

Bottom Line

Leidos (LDOS) is generally halal for Muslim investors who follow Sharia advisory boards that classify defense IT-services as general-purpose technology services. The financial screen typically passes, and the activity-level work is general-purpose IT and engineering rather than weapons production. Muslim investors who follow stricter defense-end-market screens may prefer to avoid LDOS in favor of commercial-IT-services peers without significant defense revenue.

For Muslim investors evaluating defense and government-services contractors, LDOS sits in a peer group with Booz Allen Hamilton, CACI, ICF, and Science Applications International — most of which screen halal or doubtful depending on the board's view of defense end-market exposure.
