Teradyne Rides on Strong Semiconductor Test Segment
Teradyne is benefiting from a powerful surge in its semiconductor test segment, fueled by the global build-out of AI data centers and the resulting demand for advanced compute and memory technologies. In the second quarter of 2026, Teradyne delivered a remarkable 128% year-over-year growth in its Semiconductor Test business, contributing $1.12 billion out of the company’s total $1.3 billion in sales. This segment alone accounted for 84% of total sales.
The Semi Test group, which includes System-on-Chip (SOC), memory and storage test, was a standout performer, clearing the $1 billion mark for the second consecutive quarter. SOC revenues alone reached $843 million, with compute products heavily tied to AI making up 70% of that and growing nearly 600% year over year. This growth is directly linked to the proliferation of AI applications, which are driving increased investment in wafer fabrication and advanced packaging technologies.
Teradyne’s leadership in both SOC and memory test solutions positions it to capture a significant share of this expanding market. The company’s Magnum testers are well-suited for high-bandwidth memory (HBM) and DRAM, which are seeing robust demand due to AI and data center expansion.
In the second quarter of 2026, compute revenues within SOC grew nearly 600% year over year, and memory test revenues hit a record $212 million, driven by HBM, DRAM, and renewed demand for NAND. The company is also making strategic moves in networking and optical test, acquiring Quantifi Photonics and developing new solutions for emerging technologies like co-packaged optics, which is expected to be a $300-$700 million market by 2028.
Teradyne Benefits From Strong Robotics Demand
Teradyne is benefiting from a robust performance in its Robotics segment, which has become an increasingly important driver of growth for the company. In the second quarter of 2026, Robotics revenues reached $100 million, marking a 33% year-over-year increase and a 9% rise sequentially.
Electronics manufacturing and semiconductor revenues within Robotics surged 50% from the first quarter, making it the largest end market segment in this group. This growth is closely tied to the ongoing build-out of AI data centers and the broader trend toward automation in manufacturing and assembly processes. U.S. sales rose to 32% of Robotics revenues and a U.S. manufacturing center remains on schedule to open later in 2026.
Management expects Robotics to grow in the second half as data center construction drives more rack shipments and automation demand at contract manufacturers and original design manufacturers. Over time, robot-assisted test, assembly and data center operations can widen the addressable market beyond traditional factory automation.
TER Initiates Positive Q3 Guidance
Teradyne’s expanding portfolio and strong demand for AI-related applications are expected to drive the company’s top-line growth.
For the third quarter of 2026, Teradyne expects revenues in the range of $1.20-$1.30 billion. The Zacks Consensus Estimate for third-quarter 2026 revenues is pegged at $1.27 billion, suggesting a 64.67% year-over-year increase.
For the third quarter, the company’s non-GAAP earnings are expected to be between $1.85 and $2.15 per share. The consensus mark for earnings is pegged at $1.91 per share, which has increased 36.42% over the past 30 days. This indicates growth of 124.71% on a year-over-year basis.
Teradyne’s robust, diversified portfolio, which meets the rising demand for AI-driven technologies, is consistently contributing to its growth prospects. These factors have justified its premium valuation.
