Teledyne Technologies (TDY) FY2025 results: revenue $6.1 billion, up 7.9% on the year

Teledyne makes instruments and electronics that sense, analyse and move information, sold into markets that need high reliability: aerospace and defence, factory automation, environmental monitoring, electronics design, oceanographic research, deepwater oil and gas, and medical and pharmaceutical work. It is a Delaware corporation and became an independent public company on 29 November 1999. The financial year ends in late December. Four segments: Digital Imaging, which was 52 percent of net sales in 2025, Instrumentation at 24 percent, Aerospace and Defense Electronics at 17 percent and Engineered Systems at 7 percent. Growth comes partly by purchase; four companies were bought in 2025 and two in 2024, into the first three segments, with another completed after the year end that lands in Instrumentation.

Digital Imaging

Sensors, cameras and imaging systems across the visible, infrared, ultraviolet and X-ray spectra, for industrial, scientific, government, space, defence, security and medical use. Visible-spectrum sensors and cameras go into machine vision and automated quality control as well as medical and research work. The infrared line runs from cooled and uncooled sensors to camera cores and whole systems, used in space imaging, factory condition monitoring, gas leak detection and maritime thermal imaging. The X-ray line covers high-resolution low-dose sensors and high-power microwave and high-energy subsystems for medical, dental and industrial use. The segment also makes micro electromechanical systems, high-reliability semiconductors including analog-to-digital converters and uncrewed aerial and ground systems, and it houses a research and engineering group working in electronics, materials, optical systems and information science.

Instrumentation: the sea

Undersea interconnects go to offshore oil and gas, naval defence, oceanographic and telecom customers: wet-mateable electrical and fibre-optic systems, pressure vessel penetrators, and waterproof connectors and cable assemblies. Other marine products include acoustic modems for networked underwater communication, underwater cameras and LED lighting. The company builds complete autonomous underwater vehicles, including gliders used for oceanographic research and for surveillance for the U.S. Navy, and remotely operated vehicles for maritime security, search and rescue, aquaculture and science.

Instrumentation: air, water and the laboratory

Environmental monitors measure trace gases such as sulphur dioxide, carbon monoxide and ozone, and particulates, with systems for reporting industrial stack emissions and water systems for wastewater and for detecting pathogens and contaminants. Laboratory instruments cover sample automation, elemental analysis for trace inorganic contaminants in water, food and soil, high-precision pumps, liquid chromatography for purifying organic compounds, and instruments used to measure the release rate of dosage forms. Fixed and portable gas and flame detectors go to petrochemicals, power generation, oil and gas, food and beverage, mining and wastewater treatment.

Instrumentation: test and measurement

Oscilloscopes, high-speed protocol analysers, traffic generators and emulators, sold to the people designing complex electronics in aerospace and defence, internet infrastructure, automotive, computing and semiconductors, and power electronics. There are also modular analog-to-digital conversion systems, protocol validation tools for solid-state storage, interposers that link an oscilloscope to a protocol analyser when testing PCI Express, and torque sensors used to test control valves in nuclear power and industrial plants.

Aerospace and Defense Electronics, and Engineered Systems

The electronics segment supplies components and subsystems for aircraft, radar, electronic countermeasures, weapon systems, space and satellite communications, plus harsh environment interconnects and general aviation batteries. It also sells onboard avionics and ground systems that let civil and military aircraft operators reach and use their own flight data. Engineered Systems does systems engineering, integration and complex manufacturing for defence, space, environmental and energy customers, and makes electrochemical energy systems and specialty military electronics; its customers are NASA, the U.S. Department of War, the U.S. Department of Energy, foreign militaries and commercial buyers.

Customers and contracts

No commercial customer was more than 10 percent of net sales in 2025 or 2024, for any segment or for the company. Products went to customers in over 100 foreign countries, with about 90 percent of international sales going to 30 of them; the top five, the UK, Germany, Japan, China and France, were about 20 percent of total net sales. The principal government customer is the U.S. Department of War, and except in Engineered Systems no single government programme was more than 10 percent of any segment's net sales. About 81 percent of government prime contracts and subcontracts were fixed-price in 2025, against 78 percent in 2024, so the company carries the risk that a job costs more than the agreed price. Most raw materials are readily available, though some come from a limited set of suppliers. The workforce was approximately 15,800 employees in 38 countries at 28 December 2025.
