Amphenol reported fourth-quarter revenue of $6.4 billion, up 49% year-over-year in U.S. dollars and 48% in local currencies, with organic growth of 37%. GAAP operating income for the quarter reached $1.7 billion, delivering a GAAP operating margin of 26.8%. For full-year 2025, revenue totaled $23.1 billion, a 52% increase in U.S. dollars from 2024, while adjusted operating margin was 26.2% and adjusted diluted EPS exceeded the high end of guidance. Exceptional performance was driven by broad-based strength across automotive, industrial and data-communications end markets, supplemented by contributions from five acquisitions closed during the year.

Despite robust top-line and margin expansion, shares declined following the earnings release as some investors expressed concern over the modest beat relative to prior quarters. The company’s trailing P/E ratio stands near 48, reflecting high growth expectations. Guidance for Q1 2026 projects sales of $6.90 billion to $7.00 billion, a 43% to 45% increase over Q1 2025, but implies a sequential decline in adjusted EPS to a range of $0.91 to $0.93. This outlook incorporates approximately $900 million of incremental sales and $0.02 of EPS accretion from the recently closed CommScope Connectivity and Cable Solutions acquisition.

Amphenol returned nearly $1.5 billion to shareholders in 2025, including $171 million for 1.3 million shares repurchased in Q4 and $202 million in dividend payments. The company completed five strategic acquisitions during the year, highlighted by the November closing of Trexon and the January 12, 2026, acquisition of CommScope’s Connectivity and Cable Solutions business, which is expected to generate approximately $4.1 billion in sales and add $0.15 to 2026 adjusted diluted EPS. Management emphasized ongoing investment in high-technology interconnect solutions and geographic diversification to capitalize on accelerating demand in AI-driven data centers and next-generation automotive systems.
