AND FULL YEAR 2025 RESULTS

Fourth Quarter 2025 Highlights:

Full Year 2025 Highlights:

Wallingford, Connecticut, January 28, 2026. Amphenol Corporation (NYSE: APH) today reported record fourth quarter and full year 2025 results.

"We are pleased to have closed 2025 with record fourth quarter and full-year sales and Adjusted Diluted EPS, both significantly exceeding the high end of our guidance," said Amphenol President and Chief Executive Officer, R. Adam Norwitt. "Sales in the fourth quarter and for the full year increased from prior year by 49% and 52%, respectively, driven by strong organic growth in virtually all of our end markets, including exceptional organic growth in the IT datacom market, as well as contributions from the Company's acquisition program. For both the quarter and full year we once again realized excellent profitability with Adjusted Operating Margin reaching 27.5% and 26.2%, respectively. We are extremely proud of the Company's outstanding performance during the quarter and for the full year 2025."

Throughout 2025, the Company continued to deploy its financial strength in a variety of ways to increase shareholder value. During the fourth quarter, the Company purchased 1.3 million shares of its common stock for $171 million and paid dividends of $202 million, resulting in total capital returned to shareholders of nearly $1.5 billion in 2025.

Amphenol remains focused on expanding its growth opportunities through a deep commitment to developing enabling technologies for customers across its served end markets, an ongoing strategy of market and geographic diversification as well as an active and successful acquisition program. To that end, the Company completed five acquisitions during 2025, including the previously announced closing of the Trexon acquisition in November. In addition, on January 12, 2026, the Company announced the closing of its acquisition of CommScope's Connectivity and Cable Solutions (CCS) business. As previously disclosed, Amphenol expects the CCS business to generate full-year 2026 sales of approximately $4.1 billion and add approximately $0.15 to Amphenol's 2026 Adjusted Diluted EPS.

First Quarter 2026 Outlook

Assuming the continuation of current market conditions as well as constant exchange rates, for the first quarter of 2026, Amphenol expects sales to be in the range of $6.90 billion to $7.00 billion, representing a 43% to 45% increase over the prior year quarter. Adjusted Diluted EPS is expected to be in the range of $0.91 to $0.93, representing a 44% to 48% increase from the first quarter of 2025. This guidance includes approximately $900 million in sales and $0.02 in Adjusted Diluted EPS accretion from the CCS business.

Mr. Norwitt continued, "I am very pleased with the Company's strong finish to a very successful 2025. The revolution in electronics continues to accelerate, with new innovations creating exciting growth opportunities for Amphenol across each of our diversified end markets. In turn, we have expanded our range of high-technology interconnect products, both through our organic innovation efforts as well as through our successful acquisition program. This expanded technology position coupled with our unique entrepreneurial culture has strengthened our competitive advantage. Our ongoing drive to leverage that competitive advantage and thereby create sustained financial strength has established an excellent base for the Company's future performance. I am confident in the ability of our outstanding entrepreneurial management team to continue to dynamically adjust to changing market conditions, to capitalize on the wide array of growth opportunities that arise in all market cycles and to continue to generate sustainable long-term value for our shareholders and other stakeholders."
