The increase in the gross carrying amount of intangible assets in the first three months of 2026 was primarily driven by certain customer relationships, proprietary technology, trade names and acquired backlog recognized as a result of the CommScope acquisition. Amortization expense for the three months ended March 31, 2026 and 2025 was

approximately $145.6 and $47.3, respectively. Amortization expense for the three months ended March 31, 2026 includes $46.9 related to the amortization of acquired backlog resulting from the CommScope and Trexon acquisitions. Amortization expense for the three months ended March 31, 2025 includes $10.0 related to the amortization of acquired backlog resulting from the Andrew acquisition. Amortization expense relating to the Company’s current intangible assets as of March 31, 2026 estimated for the remainder of 2026 is approximately $318.6, and for each of the next five fiscal years is approximately $387.0 in 2027, $379.8 in 2028, $368.9 in 2029, $366.2 in 2030 and $359.7 in 2031.
