Is TDY (Teledyne Technologies Incorporated) Halal or Haram?

Based on our AAOIFI-standard shariah screening, TDY is Halal and considered permissible for Muslim investors. It passed all 4 of 4 compliance screens including business activity review, debt-to-market-cap ratio (8.89% vs ≤33% threshold), interest income ratio (0.00% vs ≤5% threshold), and cash & securities ratio (1.19% vs ≤33% threshold).

Teledyne Technologies Incorporated (TDY) is a leading provider of sophisticated instrumentation, digital imaging products, and aerospace electronics. The company supplies critical hardware, including marine environmental sensors, industrial digital cameras, and electronic test equipment used across various global markets. For Muslim investors, TDY represents a strong Halal investment opportunity within the technology hardware sector. The stock successfully passes all AAOIFI shariah screens, meaning its core business activities and financial structures align closely with Islamic finance principles. From an Islamic finance perspective, Teledyne's financials are exceptionally robust. The company carries minimal leverage, with a Debt to Market Cap ratio of just 8.9%, well below the 33% threshold, and generates absolutely no impermissible interest income (0.00%). While the stock is clearly compliant today, halal investors should continue to monitor its product applications, particularly in aerospace and defense, to ensure its technologies are not predominantly repurposed for prohibited activities, though current industrial use cases remain perfectly permissible. Teledyne Technologies Incorporated operates in the Technology sector under the Hardware, Equipment & Parts industry and is headquartered in Thousand Oaks, CA, US. The company is led by CEO George C. Bobb and employs approximately 14,900 people.

TDY was screened using AAOIFI-based shariah compliance criteria. Four tests are applied: (1) Business Activity — the company's core business must not derive primary income from haram (prohibited) activities such as alcohol, gambling, tobacco, or interest-based finance. (2) Debt-to-Market-Cap — total debt must not exceed 33% of market capitalization. (3) Interest Income — interest income must not exceed 5% of total revenue. (4) Cash & Securities — cash and interest-bearing securities must not exceed 33% of market cap. TDY passed 4 of these 4 screens.

TDY has negligible interest income, so purification may not be necessary. However, it is always advisable to consult a qualified scholar regarding your specific investment situation.
