Is Teledyne Technologies Incorporated (TDY) Halal?

PASS

Teledyne Technologies Incorporated · NYSE: TDY · Industrials

The short answer

Yes -- Teledyne Technologies (TDY) passes this Shariah stock screen at all three gates. Per its own FY2025 10-K, Teledyne's principal business is enabling technologies -- digital imaging sensors, cameras, monitoring and control instruments, harsh-environment interconnects, electronic test equipment and defense electronics -- organized in four segments (Digital Imaging 52%, Instrumentation 24%, Aerospace and Defense Electronics 17%, Engineered Systems 7%): a sensors-and-instruments business, not a weapons manufacturer, and none of the classic prohibited lines appear in Item 1. Its interest-bearing debt of $2,475.4M is about 8.73% of its ~$28.37B market cap ($612.70 latest price retrieved October 2, 2026; 46,305,311 shares outstanding), below the ~33% ceiling. No separate interest income line is disclosed, so non-compliant income is effectively 0.00% of its $6,115.4M in revenue, below the 5% ceiling. Honest note: about 25.5% of 2025 net sales were U.S. Government-related, and investors applying a stricter defense screen should consult a scholar. Third-party positions, reported as found: Zoya flags TDY not Shariah-compliant (October 2026), Musaffa classifies it doubtful (October 2026), and ShariaPortfolio has no TDY coverage. This page is a factual screen, not a religious ruling.

Gate 1 — Business activity: PASS

Teledyne Technologies Incorporated (NYSE: TDY), based in Thousand Oaks, California, describes its principal business in its FY2025 10-K as enabling technologies to sense, analyze and distribute information for industrial growth markets requiring advanced technology and high reliability -- aerospace and defense, factory automation, environmental monitoring, oceanographic research, medical imaging and pharmaceutical research. It reports four segments: Digital Imaging (52% of 2025 sales), Instrumentation (24%), Aerospace and Defense Electronics (17%), and Engineered Systems (7%). None of the disclosed businesses are classic prohibited lines -- no conventional banking/lending, no insurance, no alcohol, gambling, pork, tobacco or adult entertainment. Defense exposure (honest note): about 25.5% of 2025 net sales were to agencies of, or prime contractors to, the U.S. Government ($1,203.6M to the U.S. Department of War directly), and the Digital Imaging and Aerospace and Defense Electronics segments sell defense products including multispectrum electro-optic/infrared imaging systems, radars, lasers, CBRNE detectors, and unmanned aerial and ground systems. Teledyne is not an arms manufacturer -- its core business is sensors, imaging systems and instrumentation. Some scholars apply a stricter defense screen, so investors following that view should consult a scholar. On the standard AAOIFI-style business screen, Gate 1 passes. Facts only.

Gate 2 — Debt and cash: PASS

Per Teledyne's FY2025 10-K (fiscal year ended December 28, 2025), total interest-bearing debt was $2,475.4M -- the Note 8 debt table: a $1.2B credit facility (undrawn at year end), 1.60% senior notes due April 2026 ($450.0M, current portion), 2.25% notes due 2028 ($700.0M), 2.50% notes due 2030 ($427.3M), 2.75% notes due 2031 ($910.7M), and $1.0M other debt, net of $13.6M discount/issuance costs. The filing states the company has no material finance leases. Against a market cap of about $28.37B ($612.70 latest price retrieved October 2, 2026; 46,305,311 shares outstanding per the 10-K cover), debt divided by market cap is about 8.73%, well below the ~33% ceiling. Cash and cash equivalents of $352.4M are about 1.24% of market cap. Gate 2 passes. Facts only.

Gate 3 — Non-compliant income: PASS

Teledyne's FY2025 10-K income statement reports net sales of $6,115.4M and the line interest and debt expense, net of $59.6M -- a cost, not income. No separate interest income line is disclosed in the filing (Zoya's TDY page likewise reports $0 of interest income for the FY2025 annual report), so non-compliant income is effectively 0.00% of revenue, well under the 5% ceiling. Gate 3 passes. Facts only.

Teledyne Technologies Incorporated (NYSE: TDY), based in Thousand Oaks, California, describes its principal business in its FY2025 10-K as enabling technologies to sense, analyze and distribute information for industrial growth markets that require advanced technology and high reliability, including aerospace and defense, factory automation, environmental monitoring, oceanographic research, medical imaging and pharmaceutical research. Its products include digital imaging sensors, cameras and systems, marine and environmental monitoring and control instruments, harsh-environment interconnects, electronic test and measurement equipment, aircraft information management systems, and defense electronics and satellite communication subsystems. It reports four segments: Digital Imaging (52% of 2025 net sales), Instrumentation (24%), Aerospace and Defense Electronics (17%), and Engineered Systems (7%). About 25.5% of 2025 net sales were to agencies of, or prime contractors to, the U.S. Government (the principal U.S. Government customer is the U.S. Department of War, $1,203.6M in 2025).

Why does Teledyne pass the business-activity screen despite its defense exposure?

Teledyne passes this screen at all three gates, but the defense exposure deserves an honest note. Its core business is sensors, imaging systems, and instrumentation -- enabling technologies, not arms manufacturing, and none of the classic prohibited lines (conventional banking/insurance, alcohol, gambling, pork, tobacco) appear in its Item 1 business description. That said, roughly a quarter of 2025 net sales were U.S. Government-related, and its Digital Imaging and Aerospace and Defense Electronics segments sell defense products including multispectrum electro-optic/infrared imaging systems, radars, lasers, CBRNE detectors, and unmanned aerial and ground systems. Some scholars apply a stricter defense screen, so investors following that view should consult a scholar. On the AAOIFI-style business screen applied on this site, Teledyne's business is not a weapons-manufacturing core, so Gate 1 passes. This is a factual screen, not a religious ruling.

What is Teledyne's interest-bearing debt ratio?

Per Teledyne's FY2025 10-K (fiscal year ended December 28, 2025), total interest-bearing debt was $2,475.4M -- the Note 8 debt table: a $1.2B credit facility (zero drawn at year end), 1.60% fixed rate senior notes due April 2026 ($450.0M, the current portion), 2.25% notes due April 2028 ($700.0M), 2.50% notes due August 2030 ($427.3M), 2.75% notes due April 2031 ($910.7M), plus $1.0M of other debt, net of $13.6M of debt discount and issuance costs. The filing states the company has no material finance leases. Against a market cap of about $28.37B ($612.70 latest price retrieved October 2, 2026; 46,305,311 shares outstanding per the 10-K cover), debt divided by market cap is about 8.73%, well below the ~33% ceiling. Cash and cash equivalents of $352.4M are about 1.24% of market cap. Gate 2 passes.

What is Teledyne's non-compliant income ratio?

Teledyne's FY2025 10-K income statement reports net sales of $6,115.4M and an expense line, interest and debt expense, net of $59.6M -- a cost, not income. No separate interest income line is disclosed in the filing (Zoya's TDY page likewise reports $0 of interest income for the FY2025 annual report). Because no interest-type income is disclosed, non-compliant income is effectively 0.00% of revenue, well under the 5% ceiling. Gate 3 passes.

Do Zoya, Musaffa, or ShariaPortfolio cover Teledyne?

Zoya covers TDY and flags it as not Shariah-compliant under its AAOIFI methodology (zoya.finance/stocks/tdy; the page's assessment date field was blank when accessed in October 2026) -- it does not rate Teledyne halal. Musaffa covers TDY and classifies it as doubtful as of October 2026 under its AAOIFI methodology (musaffa.com/stock/TDY/). ShariaPortfolio had no TDY screener page found. Both third-party positions are reported honestly here; this page's own screen, applied directly from Teledyne's FY2025 10-K, is PASS. This page is a factual screen, not a religious ruling -- consult a qualified scholar for personal rulings.
