TER shares have also outperformed their peers, which include Advantest Corporation (ATEYY - Free Report) and Cohu (COHU - Free Report) . Both Advantest and Cohu are expanding their footprints in the semiconductor test market. Advantest and Cohu shares have risen 124.6% and 31.1% in the trailing six-month period.
The uptick can be attributed to strong AI-related demand that is driving up huge investments in cloud AI build-out as customers accelerate production of a wide range of AI accelerators, networking, memory, and power devices.
This has primarily boosted the Semiconductor Test business. In the third quarter of 2025, Semiconductor Test revenues rose 7% year over year and 23% sequentially, accounting for 78.8% of sales in the reported quarter.

Teradyne Benefits From Expanding Portfolio
Teradyne’s expanding portfolio has been noteworthy, particularly through its focus on AI-driven technologies and semiconductor testing solutions. In October, Teradyne launched the ETS-800 D20, a new high-performance test system that aims to meet the increasing demand for precise and scalable power-semiconductor testing.
Its dual-sector design accommodates both low-volume and high-volume production, allowing for up to eight parallel test sites. With its high channel density and wide dynamic range, along with shared instruments and software across the ETS-800 platform, it provides faster testing and improved efficiency.
This development assists customers in meeting the growing demands of electric vehicles and AI-driven data centers by ensuring the reliable and accurate performance of power devices.
Teradyne Drives Robotics Growth With AI
Teradyne’s investments in robotics have been a major growth driver. The company is focusing on expanding its large customer and OEM channels while establishing its Universal Robots (UR) cobots as the preferred platform for AI-driven work cell applications.
In the third quarter of 2025, more than 8% of robotics sales were for AI-related products, up from 6% in the second quarter of 2025, showcasing the increasing adoption of AI features in robotics.
This has helped Teradyne fend off its competitors in the robotics segment from companies like ABB (ABBNY - Free Report) . ABB is also expanding its footprint in the robotics market. ABB shares have rallied 26.4% in the trailing six-month period.
Teradyne Advances High-speed Test With UltraPHY 224G
Teradyne’s UltraFLEXplus system, designed for high-performance processors and networking devices, has proven to be a key catalyst in meeting the demanding requirements of AI compute and networking devices. UltraFLEXplus enables customers to reduce test development times, driving up high-efficiency volume production.
Building on this momentum in September, Teradyne announced the launch of its UltraPHY 224G instrument for the UltraFLEXplus platform. This expands its high-speed PHY test capabilities beyond the UltraPHY 112G. The new solution offers bench-quality 224G performance.
It includes integrated DSO, AWG, and BERT functionality to meet the needs of next-generation data center and silicon photonics interfaces. Both UltraPHY 224G and 112G can work together in the same tester, allowing for complete coverage of current and future high-speed standards. The scalable design uses Teradyne’s IG-XL software and over 50 GHz signal delivery. This setup creates a fully integrated, production-ready test environment.
TER’s Initiates Positive Q4 Guidance
Teradyne’s expanding portfolio and strong demand for AI-related applications are expected to drive the company’s top-line growth.
For the fourth quarter of 2025, Teradyne expects revenues between $920 million and $1 billion. The Zacks Consensus Estimate for fourth-quarter 2025 revenues is pegged at $815.84 million, suggesting an 8.36% increase year over year.
