Why analysts are watching it
Analysts are watching Teradyne (TER) due to its strong performance in the AI sector and recent strategic moves. On May 19, 2026, Business With Brian explained in his video "I've Bought Every AI Correction Since 2018. Here's My List" that Teradyne reported Q1 results that beat expectations on every metric, with earnings per share growing 241% year over year and AI-related demand making up nearly 70% of their total revenue. Despite this, Business With Brian observed that the stock fell 19% on the news. He also highlighted that Teradyne's Magnum memory tester provides a lead in high-bandwidth memory (HBM) testing, a critical component for AI accelerators, and noted the company's expansion into AI data center connectivity and test software through investments like the $157 million joint venture in Multilane Test Products and the acquisition of Test in Sight. Business With Brian further clarified that Teradyne, as a semiconductor equipment company, makes the test platforms necessary for all chips, including Nvidia GPUs and AMD CPUs, before they are shipped. The risk remains that a significant portion of their revenue is tied to the volatile AI market.

"The technology is test platforms specifically designed for high bandwidth memory. The kind of memory that sits right next to every AI accelerator. Their Magnum memory tester gives them a lead in HBM testing that competitors are still trying to catch up to."

"Their drive is to expand into AI data center connectivity and test software. They just invested $157 million in a joint venture called Multilane Test Products and acquired a software company called Test in Sight, adding capabilities for testing AI infrastructure from end to end."

"And the next name on the list is Teradyne, a semiconductor equipment company built directly into the AI chip production line. Once again, now Teradyne doesn't make chips. They make the test platforms that every chip has to pass through before it ships. They make the equipment that determines whether the Nvidia GPUs or the AMD CPUs actually work before they ship them."
