Amphenol Corporation reports strong Q1 2026 results and closes the large CommScope Connectivity and Cable Solutions acquisition. Net sales rose to $7,620.1 million from $4,811.0 million, while net income attributable to Amphenol increased to $933.0 million and diluted EPS reached $0.72, up from $0.58.
Growth reflects both underlying demand and the addition of CommScope, which contributed net sales of $871.5 million but a small net loss due to heavy amortization and inventory step-up costs. Operating income climbed to $1,831.8 million, though the effective tax rate jumped to 42.7% from 22.7%, driven by a $130.0 million accrual and an additional $160.0 million tax obligation related to a China tax matter.
The CommScope deal, at a cash purchase price of about $10,592.9 million, was funded with new U.S. and Euro senior notes, two $1,534.1 million delayed draw term loans, and cash on hand, pushing total assets to $42,133.8 million and total debt to $18,748.9 million. Goodwill rose to $17,542.9 million and definite-lived intangibles to $5,132.0 million, highlighting the scale of recent acquisitions. The company also continued returning capital via dividends of $307.4 million and share repurchases of $178.0 million, while maintaining an undrawn $3,000.0 million revolving credit facility and no commercial paper outstanding.
Amphenol Corp ownership disclosure: Vanguard Capital Management reports beneficial ownership of 91,856,807 shares of Common Stock, representing 7.47% of the class as of 03/31/2026. The filing shows 11,981,351 shares with sole voting power and full dispositive power over the reported position.
Amphenol Corporation reported record first quarter 2026 results, with very strong growth and margins. Net sales rose to $7.62 billion, up 58% from a year earlier, driven by broad organic growth, especially in IT datacom, and contributions from acquisitions including CommScope. GAAP diluted EPS was $0.72, but excluding acquisition-related costs, inventory step-up amortization and tax items, Adjusted Diluted EPS reached $1.06, above the high end of guidance. Adjusted operating margin expanded to 27.3%, reflecting strong profitability.
The company also booked record orders, resulting in a book-to-bill of 1.24, indicating demand exceeded shipments. Amphenol returned nearly $485 million to shareholders in the quarter through $178 million of share repurchases and $307 million of dividends. Operating cash flow was $1.12 billion and free cash flow was $831.2 million, supporting ongoing investments and the large CommScope acquisition.
For the second quarter of 2026, Amphenol expects sales of $8.1–$8.2 billion, up 43–45% year over year, and Adjusted Diluted EPS of $1.14–$1.16, implying 41–43% growth versus the prior-year quarter.
