Is Mercury Systems (MRCY) stock Halal?
Mercury Systems, Inc. (MRCY) is not Shariah compliant in the September 2026 AAOIFI screening: it fails the non-permissible income screen. Tabadulat re-screens MRCY monthly, and a stock can return to compliance when new financial reports change its ratios.
Mercury Systems is a cutting-edge aerospace and defense technology company. It specializes in the design, manufacture, and commercialization of secure, sensor and safety-critical processing subsystems for the United States defense industry. Its products are vital for mission-critical applications, enabling real-time data processing in environments that demand enhanced security and reliability. Mercury Systems works closely with defense contractors and governmental agencies, providing solutions that enhance military operations across air, land, and sea domains. Before any of that matters to a Muslim investor, one question comes first: is Mercury Systems stock Halal?
Is Mercury Systems Shariah compliant?
Industrial businesses like Mercury Systems usually pass the activity screen without drama. The harder test is financial: heavy assets mean heavy financing, and AAOIFI Shariah Standard No. 21 tolerates interest bearing debt and investments only below 30% of market capitalisation, ratios that shift with every move in the share price.
Does Mercury Systems pass the business activity test?
The activity screen is only part of the picture this month: Mercury Systems currently fails the non-permissible income screen, so the overall verdict is not compliant regardless of the business itself. The activity itself raises no Shariah objection; the scrutiny belongs to the financing.
Is Mercury Systems' income Halal?
No. Mercury Systems' income from impermissible sources currently exceeds AAOIFI's 5% revenue ceiling, which makes the stock non-compliant on this screen regardless of the others. The screen is reassessed monthly, so the status can change when new financial statements arrive.
Does Mercury Systems meet AAOIFI's debt and investment ratio requirements?
Yes. Both caps hold this month: interest bearing investments and interest bearing debt each stay below 30% of market capitalisation. Because the caps move with the share price, our Shariah Supervisory Board has MRCY re-screened every month, and the result above always shows the latest verdict.
