Teledyne Technologies Inc. reported a stronger first quarter of 2026, with sales and earnings rising from the prior-year period as demand improved across most of its business lines and recent acquisitions added revenue. The quarterly report covers the period ended March 29, 2026, and was filed April 24, 2026. For the first quarter, Teledyne posted net sales of $1.560 billion, up 7.6% from $1.450 billion in the first quarter of 2025. Operating income rose 13.5% to $294.2 million from $259.3 million. Net income attributable to Teledyne increased 20.3%, and diluted earnings per share were $4.85, compared with $3.99 a year earlier. The company said the improvement was driven primarily by higher sales and a stronger overall operating margin. Costs rose with the higher revenue base, but margins improved in several areas. Cost of sales increased to $886.3 million from $830.4 million, while cost of sales as a percentage of sales declined to 56.8% from 57.3%. Selling, general and administrative expense increased modestly to $237.4 million from $233.9 million, but fell as a percentage of sales to 15.2% from 16.1%. Research and development expense increased to $84.6 million from $74.3 million, primarily reflecting higher spending in Digital Imaging. Acquired intangible asset amortization increased to $57.6 million from $52.0 million, mainly due to acquisitions completed in 2025 and 2026. Recent acquisitions contributed $33.3 million of incremental first-quarter sales, spread across Digital Imaging, Instrumentation, and Aerospace and Defense Electronics. Digital Imaging remained the company’s largest segment, with sales rising 7.9% to $816.9 million from $757.0 million and operating income increasing 15.9% to $141.7 million. The gains were driven by higher sales of infrared imaging detectors, components and subsystems for defense and commercial uses, as well as surveillance and unmanned air systems for defense applications. Recent acquisitions added $8.0 million of Digital Imaging revenue. Instrumentation sales increased 5.3% to $361.4 million, helped by stronger Marine Instrumentation and Environmental Instrumentation demand, including offshore energy, defense markets and gas detection products. However, segment operating income fell 4.6% to $88.4 million, reflecting unfavorable product mix. Recent acquisitions added $5.0 million of Environmental Instrumentation sales. Aerospace and Defense Electronics was the fastest-growing segment, with sales up 14.4% to $277.5 million and operating income up 28.2% to $71.4 million. The increase was driven by a $36.1 million rise in defense electronics sales, partially offset by a $1.1 million decrease in aerospace electronics. Recent acquisitions contributed $20.3 million of incremental defense electronics revenue. Engineered Systems sales declined 2.6% to $104.3 million due to lower engineered products sales, but operating income improved to $11.7 million from $8.3 million because of favorable program mix. Teledyne also reported lower net interest and debt expense, which declined to $12.3 million from $17.3 million because of reduced outstanding borrowings. Other expense was $5.9 million, primarily from foreign currency exchange losses. The company’s effective tax rate fell to 18.6% from 21.0%, aided by $8.0 million of net discrete income tax benefits in the 2026 quarter. Teledyne also noted that the “One Big Beautiful.
