Edwin Roks
Chief Executive Officer at Teledyne Technologies
Thank you, Robert. This is Edwin and I will report on the -- first report on the digital imaging segment, which represents 54% of Teledyne's portfolio. And like Teledyne as a whole, this segment is a mix of longer cycle businesses such as defense, space and healthcare combined with shorter cycle markets, including industrial automation, semiconductor inspection and infrared components and cameras for applications ranging from factory condition monitoring to maritime navigation. Second quarter 2024 sales declined 6.8% compared with last year. As expected, sales to industrial machine vision markets declined approximately 30% year-over-year. However, this was partially offset by increased sales from FLIR defense and from generalized space-based infrared imaging detectors. Furthermore, for the fourth consecutive quarter, healthy margins across the entire FLIR business portfolio helped us protect overall operating margin even given the significant year-over-year production in sales of our typically highest contribution margin product lines.
I will now report on the other three segments, which represent the remaining 46% of Teledyne. The instrumentation segment consists of marine, environmental and test and measurement businesses which contribute a little over 24% of sales. For the total segment, overall second quarter sales increased 1.6% versus last year. Sales of marine instruments increased 60% in the quarter, primarily due to strong offshore energy and subsea defense. Sales of environmental instruments decreased 1.6% with greater sales of drugs discovery and laboratory instruments, offset by lower sales of processed gas, emission monitoring systems and gas flame safety analyzers. Sales of electronics and measurement systems which include oscilloscopes, digitizers and protocol analyzers decreased 50.8% year-over-year on a tough quarterly comparison versus 2023. Overall instrumentation segment operating profit increased in the second quarter with GAAP operating margins increasing on a 36 basis points to 26.1% and 134 basis points on a non-GAAP basis to 27.2%.
In the Aerospace and Defense Electronics segment which represents 14% of Teledyne sales, second quarter sales increased 4.5% driven by the growth of commercial aerospace and defense microwave products. GAAP and non-GAAP segment operating profits increased year-over-year with segment margin increasing approximately 77 basis points. For the engineered system segment which contributes 8% to overall sales, second quarter revenue decreased 8.7% and operating profit was impacted by lower sales and unfavorable program mix.
I will now pass the call back to Robert.
