Arista Networks Stock Rises 56% in a Year Amid AI Networking Demand

Amphenol's IT datacom business, which represented 43% of the company's total sales in the second quarter of 2026, saw revenues surge 89% year over year and 63% organically, with management saying the AI revenue run rate has reached roughly $10.5-$11 billion. Management noted that virtually all of the 22% sequential IT datacom growth in the quarter came from AI-related products, as customers require more copper, optics and power for larger, more complex AI clusters. The company's acquisition of CommScope contributed more than $1.2 billion in sales in the quarter, with CommScope's IT datacom business nearly doubling year over year; management expects that market to account for just under half of CommScope's 2026 sales, compared with roughly one-third in 2025. Amphenol faces tough competition from TE Connectivity, whose Digital Data Networks sales rose 34% year over year in the third quarter of fiscal 2026 with bookings up more than 70% year to date, and from Marvell Technology, whose data-center revenues increased 46% year over year to $2.17 billion in the second quarter of fiscal 2027. Amphenol shares have risen 16% year to date, trailing the broader Zacks Computer and Technology sector's 17% gain, and trade at a forward 12-month price/earnings of 25.32X versus the sector's 20.38X, while the Zacks Consensus Estimate for earnings stands at 72 cents per share, up 5 cents over the past 30 days and implying 53.19% growth.
