Amphenol Corporation reported fourth-quarter revenue of $6.4 billion, a 49% increase in U.S. dollars and 48% in local currencies versus Q4 2024, driven by 37% organic growth. Full-year 2025 revenue reached $23.1 billion, up 52% in U.S. dollars, with GAAP operating income of $1.7 billion and an operating margin of 26.8%. Adjusted operating margin for the full year was 26.2%, reflecting exceptional profitability across multiple end markets including IT datacom and automotive.

The Communications Solutions segment delivered $3.4 billion in Q4 sales, up 78% in U.S. dollars and 60% organically, with an operating margin of 32.5%. Exceptional organic growth was also recorded in the IT datacom market, contributing to adjusted diluted EPS growth of 76% year-over-year. The company realized adjusted operating margins of 27.5% in Q4 and 26.2% for the full year, underscoring disciplined cost management and pricing leverage across its interconnect and sensor businesses.

During 2025 Amphenol completed five acquisitions, including Trexon in November, and in January 2026 closed the CommScope Connectivity and Cable Solutions business, which is expected to add approximately $4.1 billion in full-year sales and $0.02 per share to 2026 adjusted EPS. The company returned nearly $1.5 billion to shareholders in 2025 through $171 million of share repurchases in Q4 and $202 million in dividends, reflecting a commitment to capital allocation and balance sheet strength.

For Q1 2026 Amphenol expects sales of $6.90 billion to $7.00 billion, a 43% to 45% increase over the prior year quarter, and adjusted diluted EPS of $0.91 to $0.93, up 44% to 48% from Q1 2025. Despite these strong metrics, shares initially declined on post-earnings valuation concerns, with the company trading at a high price-to-earnings multiple that reflects investor expectations for sustained double-digit growth and ongoing demand from AI-driven data centers.
