Teradyne's UltraFLEXplus Gains Traction: A Sign for More Upside?
Read MoreHide Full Article
Key Takeaways
Teradyne's UltraFLEXplus is driving higher Semiconductor Test revenue through faster, more efficient testing.
TER's Semiconductor Test revenues rose 7% year over year and 23% sequentially in Q3 2025.
Teradyne expanded UltraFLEXplus with UltraPHY 224G to support next-generation high-speed standards.
Teradyne (TER - Free Report) is benefiting from the growing demand for its UltraFLEXplus system, which has been specifically designed to address the complex testing requirements of high-performance processors and networking devices. UltraFLEXplus enables customers to reduce test development times, driving up high-efficiency volume production.
The UltraFLEXplus system has proven to be a key driver in boosting 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.
Building on this momentum in September 2025, 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.
The launch 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.
The growing demand for AI-driven applications, particularly in data centers, is expected to continue driving the adoption of UltraFLEXplus. Strong demand for the UltraFLEXplus system is expected to drive top-line growth. For the fourth quarter of 2025, Teradyne expects revenues between $920 million and $1 billion.
Teradyne Suffers From Stiff Competition
Teradyne is facing stiff competition in the semiconductor test market from companies such as Advantest Corporation (ATEYY - Free Report) and Cohu (COHU - Free Report) .
Advantest’s expanding footprint in the semiconductor test market has been noteworthy. Advantest recently announced the T2000 AiR2X, a next-generation air-cooled semiconductor test system that provides double the test resources of its predecessor while keeping power use low and its design compact. This platform focuses on evaluation and high-mix, low-volume production needs. It supports a wide range of devices and replaces older air-cooled test systems.
Cohu’s expanding portfolio has been noteworthy. The company has introduced innovative solutions, including the Eclipse platform, designed for seamless integration into diverse applications and providing flexibility to support evolving high-performance processor roadmaps. Additionally, Cohu has secured new orders for its Krypton system, enabling advanced optical inspection for high-bandwidth memory devices, further strengthening its position in the semiconductor test market.
