Strong Datacenter Growth Boosts TER's Prospects Against CSCO & VRT

Teradyne TER is benefiting from accelerating AI-driven data-center investments, which are expanding demand across semiconductor test, networking, storage, product test and robotics. This momentum is strengthening Teradyne’s prospects in the broader data-center infrastructure ecosystem alongside Cisco Systems CSCO and Vertiv Holdings VRT. More than 60% of Teradyne’s second-quarter 2026 revenues were AI-driven, underscoring the success of its wafer-to-AI-data-center strategy.

A key driver of Teradyne’s momentum is the acceleration in semiconductor capital expenditures, especially in wafer fabrication equipment (WFE). As WFE CapEx is forecasted to approach $250 billion by the end of the decade, this is expected to drive 5% to 10% annual growth in wafer production and 15% to 20% compound annual growth in total transistor production. The increase in wafer and transistor production directly boosts demand for automated test equipment. 

Teradyne’s leadership in both SOC and memory test solutions, especially for high-bandwidth memory (HBM) and DRAM, ensures it is well-placed to capitalize on this growth. The company’s memory business also saw revenues exceed $200 million for the third consecutive quarter in the second quarter of 2026, driven by strong demand for HBM and DRAM and a revival in NAND testing. 

Growth is being reinforced by Quantifi Photonics and the Multilane Test Products JV, which expand Teradyne’s exposure to optical and high-speed interconnect testing. The company expects the Co-Packaged Optics testing market alone to reach $300-$700 million by 2028. Robotics is also benefiting as AI data-center construction boosts automation demand in electronics manufacturing and semiconductor production.

Teradyne expects sustained AI data-center build-outs to drive greater demand for compute, networking, memory, product-test and automation solutions, strengthening its position across the broader infrastructure ecosystem that includes Cisco Systems and Vertiv. The company expects third-quarter 2026 revenues between $1.20 billion and $1.30 billion.

How Competitors Fare Against TER

Teradyne is facing stiff competition from companies such as Cisco Systems and Vertiv. Both companies are also expanding their footprints in the AI and data center markets. 

Cisco Systems is benefiting from strong data center growth by capturing surging demand for AI infrastructure and networking solutions, with data center networking orders growing more than 35% year over year in the fourth quarter of fiscal 2026. The company’s comprehensive portfolio, which includes Silicon One-powered systems, optics and integrated security, positions it as a key provider for hyperscalers and enterprises modernizing their data centers to support advanced AI workloads.

Vertiv is benefiting from the robust demand for AI-driven infrastructure, which is driving significant growth in the data center market. The company’s robust demand across its core markets, particularly in the Americas and APAC regions, remains noteworthy. In the second quarter of 2026, net sales increased 24% year over year, with the Americas and APAC both growing 29%. EMEA also returned to positive net sales growth.
