APH's Communications Growth Surges: Can Rivals Dent Its Momentum?

Amphenol APH is riding on strong growth in its Communications Solutions segment, supported by surging AI-related IT datacom demand and contributions from acquisitions. In the second quarter of 2026, Communications Solutions revenues jumped 85% year over year and 42% organically, representing roughly 62% of total revenues. Growth was primarily driven by outsized IT datacom demand, particularly for AI applications, along with strength in industrial, mobile-device and automotive markets. 

AI infrastructure remains the biggest growth engine and is helping the company fight off competition from the likes of TE Connectivity TEL and Bel Fuse BELFB. IT datacom accounted for 43% of Amphenol’s quarterly sales and grew 89% year over year and 63% organically. Sequential growth reached 22%, with virtually all of the increase attributed to AI-related products. Amphenol expects another mid-teen sequential increase in the third quarter as AI data-center investments accelerate and cloud and enterprise customers expand infrastructure spending. Its exposure spans high-speed copper, fiber-optic and power interconnect solutions, allowing it to capture rising connectivity content across AI systems.

Acquisitions are further strengthening this position. CommScope’s IT datacom business, focused on advanced optical interconnect solutions, nearly doubled year over year, while Amphenol raised CommScope’s expected 2026 revenues to $4.6 billion from $4.1 billion. Wilder Technologies also expands APH’s capabilities in high-speed digital, RF and signal-integrity applications.

For the third quarter of 2026, APH expects sales of $9.3-$9.4 billion. The range implies year-over-year growth of 50-52%, assuming current market conditions and constant exchange rates. Adjusted earnings are projected between $1.40 and $1.42 per share, representing growth of 51-53% from the prior-year quarter.

How Rivals Stack Up Against APH

TE Connectivity poses significant competition in AI connectivity. TEL’s Digital Data Networks revenues increased 34% year over year to $813 million in the third quarter of fiscal 2026, while Industrial Solutions revenues advanced nearly 22%. The company is benefiting from rising demand for connectivity technologies that distribute power, signal and data across AI-enabled data centers, with AI momentum helping drive record companywide orders of $5.7 billion, up 27% year over year.

Bel Fuse is a smaller but growing challenger. The company’s Data Solutions revenues surged 55% year over year to roughly $58 million as recent high-performance-computing project wins began ramping. Bel Fuse is also seeing stronger demand for integrated connector modules and RF connectors, while bookings remain strong across Data Solutions and distribution channels. This growing HPC and connectivity exposure could increase competitive pressure on APH for specialized interconnect and power content in next-generation computing infrastructure.
