Amphenol posted record fourth-quarter 2025 revenue of $6.4 billion, a 49 percent increase in U.S. dollars versus the year-ago period, with 48 percent growth in local currencies and 37 percent organic expansion. Full-year 2025 sales reached $23.1 billion, up 52 percent in U.S. dollars. GAAP operating income for Q4 was $1.7 billion, yielding a 26.8 percent operating margin, while the Communications Solutions segment delivered $3.4 billion in sales—up 78 percent in U.S. dollars and 60 percent organically—with a 32.5 percent margin contribution.

During Q4, the company repurchased 1.3 million shares for $171 million and paid $202 million in dividends. In 2025, total capital returned to shareholders approached $1.5 billion. The acquisition of CommScope’s Connectivity and Cable Solutions business closed in January 2026; this unit is expected to contribute approximately $4.1 billion in 2026 sales and add about $0.15 to adjusted EPS. Amphenol completed five acquisitions over the past year, reinforcing its market and geographic diversification strategy.

Seaport Global has set a price target implying over 40 percent upside, citing robust end-market demand and margin resilience. First-quarter 2026 guidance calls for sales of $6.90 billion to $7.00 billion (up 43 percent to 45 percent year-over-year) and adjusted diluted EPS of $0.91 to $0.93 (up 44 percent to 48 percent), including roughly $900 million of sales and $0.02 of EPS accretion from the recent acquisition. The forward P/E ratio stands at approximately 48, reflecting strong growth expectations but also valuation scrutiny after a modest earnings beat and sequential EPS forecast decline.
