Read MoreHide Full Article

Key Takeaways

  • Teradyne's Semiconductor Test sales jumped 128% year over year to $1.12B in Q2 2026.
  • New UltraFLEXplus tools target AI and data-center digital, PCIe Gen6 and high-power test needs.
  • Teradyne expects Q3 revenues of $1.20-$1.30B as AI demand supports UltraFLEXplus adoption.

Teradyne (TER - Free Report) is benefiting from accelerating artificial intelligence (AI)-driven semiconductor test demand, particularly across high-performance compute, networking, and advanced memory applications, positioning the company as a formidable player against KLA (KLAC - Free Report) and Cohu (COHU - Free Report) . The company’s growing demand for its UltraFLEXplus system, which is designed to address the complex testing requirements of high-performance processors and networking devices, has been noteworthy. UltraFLEXplus enables customers to reduce test development time, driving higher-efficiency volume production.

Building on this momentum, Teradyne recently launched three new instruments for its UltraFLEXplus semiconductor test platform to address growing AI and data-center computing requirements. The UltraPin5000-EM offers expanded vector memory and faster pattern loading for complex AI devices, while UltraPort-PCIe6 supports PCIe Gen6 testing at 64 Gbps across 32 lanes. The UltraVS64-HP delivers up to 1,280 amps per instrument to test increasingly power-intensive compute devices. Together, the products expand UltraFLEXplus capabilities across advanced digital, high-speed interface and power testing, supporting semiconductor manufacturers from wafer probe through final device validation.

The UltraFLEXplus system has proven to be a key driver in boosting the Semiconductor Test business. 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 growing demand for AI-driven applications, particularly in data centers, is expected to continue driving the adoption of UltraFLEXplus. The strong demand for UltraFLEXplus is likely to support top-line growth, strengthening Teradyne’s competitive position against KLA and Cohu in the semiconductor test market. For the third quarter of 2026, Teradyne expects revenues in the range of $1.20-$1.30 billion.

How Competitors Fare Against TER

Teradyne is facing stiff competition from companies such as KLA and Cohu. Both companies are expanding their footprint in the AI space.

KLA is benefiting from the growing demand for AI through its leadership in process control and its ability to address growth markets in wafer fab equipment, including high-bandwidth memory and advanced packaging.

In May 2026, Cohu received approximately $5 million in multiple orders for its Diamond X platform from a leading semiconductor manufacturer. The systems will support testing of next-generation GaN power devices for AI data centers, strengthening Cohu’s position in AI infrastructure and high-efficiency power semiconductor testing.
