Is Leidos (LDOS) stock halal?
Leidos (LDOS) passes Dow Jones Islamic but fails AAOIFI, S&P Shariah and MSCI Islamic on debt. It is borderline under Dow Jones Islamic and S&P Shariah, so a small price move could flip that verdict.
Passes 1 of 4 standards Screened 28 September 2026 on that day's price. Market-value tests move with the share price.
The four standards
| Standard | Debt measured against | Debt ratio | Limit | Verdict |
|---|---|---|---|---|
| AAOIFI | market capitalisation on the day | 41.5% | 30.0% | Fails on debt |
| Dow Jones Islamic | trailing 24-month average market capitalisation | 33.2% | 33.3% | Borderline pass |
| S&P Shariah | trailing 36-month average market capitalisation | 33.5% | 33.3% | Borderline fail |
| MSCI Islamic | total assets | 41.2% | 33.3% | Fails on debt |
Debt ratio is interest-bearing debt over each standard's own size measure. A company whose main business a standard excludes is never compliant under it, whatever its debt.
Business screen
| Industry (SEC code) | Services-Computer Integrated Systems Design (7373) |
|---|---|
| Main business | permitted |
| Income from side activities | not checked (needs segment revenue) |
The figures
| Market value | $15.3 billion |
|---|---|
| Interest-bearing debt (30 June 2026) | $6.3 billion |
| Total assets (30 June 2026) | $15.4 billion |
Debt and assets from SEC XBRL company facts; price from live market data.
At least one ratio sits within one percent of its threshold, where a small price move flips the verdict.
Each standard also limits income from prohibited side activities (usually to 5% of revenue). That needs the company's segment revenue, which Mizan does not read yet, so check it for companies with a mixed business.

How Mizan screens
First the business: a standard that excludes the company's main business (from its SEC industry code and Mizan's list of named companies) marks it non-compliant. Then the debt: interest-bearing debt over each standard's own size measure, compared with that standard's threshold. Averaged denominators use the trailing quarterly market capitalisations of the study panel with today's market capitalisation as the final observation.
Research behind it: Price-Driven Churn in Islamic Equity Screening (SSRN). Where the standards disagree.
Mizan reports how four published screening standards read a company's own filings and market price. It is research output, not investment advice and not a fatwa.
