Why is Teradyne, Inc. Common Stock (TER) stock moving?
Teradyne reported a strong Q3 2026, with revenue of $1,306M (up 70% year over year) and non-GAAP EPS of $2.29, above the high end of its guidance. Memory and Integrated Systems Test set records, and Robotics reached profitability. The Q4 guidance, however, is revenue of $1,250M to $1,350M and non-GAAP EPS of $1.95 to $2.25, with the midpoint below the Q3 actual, and the stock sold off hard after the report. The close fell from a 328.83 intraday high on Oct 27 to a 211.63 low on Nov 5, roughly 36% lower, on heavy volume: 11.09M shares that day, more than double the recent average. Analysts stayed constructive but cut targets, with UBS at $430 (from $485), Baird at $385 (from $420) and BofA at $450, all still well above the 245.40 close on Nov 10. ARK disclosed a significant purchase, and a CNBC guest said he bought the stock. Since the Nov 5 low, the price has rebounded about 16%, with the Nov 9 session on 5.36M shares supported by the Omnyx Edge launch for AI-related circuit board testing. Overall, fundamentals and analyst support are firm, but the Q4 guide and the sharp drawdown leave the near-term direction unclear.

About Teradyne, Inc. Common Stock
Teradyne is a Massachusetts-based maker of automated test equipment that checks chips, electronics and systems for defects, and it also owns the collaborative-robot (cobot) maker Universal Robots and Mobile Industrial Robots. What sets it apart is its major position in testing AI processors and memory chips. The company says more than 60% of its revenue now comes from AI-related demand.
How it makes money
Most of its revenue comes from Semiconductor Test, meaning testers like UltraFLEXplus and Magnum sold to chipmakers and contract test houses for compute, memory (including high-bandwidth memory) and other chips. That segment brought in about 82% of Q3 2026 revenue of roughly $1.3 billion. Product Test (about 11%) covers system-level and board testing, and Robotics (about 7%) sells cobots and autonomous mobile robots. Service and support add recurring income.
