Amphenol posts record Q2 on AI infrastructure surge, raises CommScope outlook

Amphenol delivered record second-quarter results as surging demand for AI infrastructure drove broad-based growth across its portfolio. The company reported adjusted earnings per share of $1.35, beating the Zacks Consensus Estimate of $1.19, and revenues of $8.76 billion, exceeding the estimate of $8.30 billion. Orders reached a record $10.7 billion, yielding a book-to-bill ratio of 1.23:1.

The standout driver was the IT datacom market, where demand for AI infrastructure products accelerated sharply. IT datacom sales surged 89% year over year and grew 63% organically. CEO R. Adam Norwitt said customers are aggressively pursuing high-speed copper, fiber optic solutions, and power interconnect products as AI infrastructure expands. He noted that Amphenol's broad portfolio allows it to participate across multiple evolving architectures, reducing the company's exposure to a single technology path.

The Communications Solutions segment, bolstered by the CommScope acquisition, generated $5.4 billion in sales, up 85% year over year, with a segment operating margin of 33.6%. When pressed by a Jefferies analyst, Norwitt said CommScope has grown broadly, with particularly strong progress in IT datacom and AI-related optical interconnect applications. CommScope's IT datacom business has nearly doubled year over year, supported by its advanced optical interconnect solutions and Amphenol's customer relationships across the AI ecosystem. CFO Craig Lampo emphasized that CommScope's improved profitability has been driven by operating execution, factory improvements, and expense control rather than pricing, and noted the business operated with margins exceeding 20% during the quarter, including acquisition-related amortization.

Amphenol also reported strength in other end markets. The Harsh Environment Solutions segment generated $1.9 billion in sales, up 28% year over year. Defense sales grew 37% year over year and 24% organically, with management expecting third-quarter defense sales to increase in the low double-digit range from Q2 levels. Industrial sales rose 56% year over year and 18% organically, with growth across instrumentation, factory automation, electrification, battery storage, heavy equipment, and alternative energy.

Management significantly raised its expectations for the CommScope acquisition. Full-year 2026 sales are now projected at $4.6 billion (versus $4.1 billion previously) and adjusted EPS accretion at $0.30 (versus $0.15). Norwitt said the integration has benefited from CommScope employees embracing Amphenol's entrepreneurial culture and leveraging broader customer relationships.

For the third quarter, Amphenol expects sales of $9.3 billion to $9.4 billion and adjusted EPS of $1.40 to $1.42, implying 50–52% sales growth and 51–53% EPS growth year over year. Management expects IT datacom sales to continue rising in the third quarter, forecasting mid-teens sequential growth as AI data center investments accelerate. Norwitt stressed that customers remain focused on increasing interconnect content regardless of whether future architectures use copper, fiber, or different backplane designs.

During the quarter, Amphenol completed acquisitions of El.Com and Wilder Technologies, expanding its interconnect capabilities in industrial, defense, aerospace, and high-speed digital applications. The company generated $1.6 billion in operating cash flow and $1.2 billion in free cash flow and returned approximately $515 million to shareholders through repurchases and dividends. Adjusted operating margin reached a record 29.8%, up 420 basis points year over year and 250 basis points sequentially.
