Amphenol delivered exceptional first quarter 2026 results, propelling shares significantly higher during Wednesday’s premarket session.
The company reported quarterly sales of $7.62B for the period ending March 31, representing a 58.4% increase compared to the prior year period. This figure substantially exceeded analyst projections of $7.08B.
Adjusted earnings per share reached $1.06, surpassing the consensus forecast of $0.94. The company achieved an adjusted operating margin of 27.3% during the quarter.
The company generated $1.1B in operating cash flow during the quarter, with free cash flow totaling $831M.
Chief Executive Officer R. Adam Norwitt highlighted that the quarter concluded with record-breaking sales and adjusted diluted earnings per share, both surpassing the upper range of company guidance. He emphasized robust organic expansion across the majority of end markets.
The IT datacom sector received particular attention, with Norwitt characterizing performance in this segment as “exceptional.” Connector and sensor system demand has accelerated as technology companies expand data center infrastructure to support artificial intelligence computing requirements.
Record Orders and a Strong Book-to-Bill
Amphenol registered record order levels during Q1, achieving a book-to-bill ratio of 1.24:1. This metric indicates the company is receiving more orders than it fulfills — a positive indicator for upcoming demand trends.
Second quarter projections proved equally impressive. The company forecasts adjusted EPS between $1.14 and $1.16 for the upcoming quarter, surpassing the analyst consensus of $1.05.
Second quarter revenue guidance stands at $8.1B to $8.2B, well above Wall Street’s $7.7B expectation.
CommScope Deal Adds Weight
This past January, Amphenol finalized its $10.5B acquisition of CommScope’s Connectivity and Cable Solutions division. This strategic transaction broadened the company’s portfolio in fiber-optic solutions and data center connectivity technologies.
The acquisition played a significant role in the substantial year-over-year revenue increase, complementing strong organic growth. Norwitt acknowledged both the organic performance momentum and the strategic acquisition program in his remarks.
Management will conduct a conference call at 1 p.m. EST to provide comprehensive details on the quarterly performance.
Premarket trading showed gains exceeding 9% during early Wednesday activity, with investors responding enthusiastically to both the first quarter performance and second quarter projections.
Amphenol’s Q2 revenue forecast reaching $8.2B at the high end stands approximately $500M above the LSEG-compiled analyst estimate of $7.69B at the guidance midpoint.
The 27.3% adjusted operating margin achieved in Q1 demonstrates sustained profitability management alongside accelerated revenue expansion.
