Teradyne jumps 7.2% as Apple-Intel deal lifts chip sector
Teradyne shares surged 7.2% in heavy trading after the Apple-Intel foundry deal sparked a broad semiconductor rally, though earnings estimate revisions suggest limited upside ahead.
Teradyne shares jumped 7.2% on above-average volume after President Trump announced Apple agreed to manufacture chips with Intel in the US, a foundry commitment that lifted the entire semiconductor test equipment sector.
"The deal serves as a direct boost for Intel and lifted sentiment across the industry," Art Hogan, chief market strategist at B Riley Wealth, said. The announcement ended over a year of market anticipation for a major foundry customer win at Intel's US facilities.
Teradyne's AI-related revenue accounted for nearly 70% of total sales in the first quarter of 2026, up from about 60% in the prior quarter, as demand for data center infrastructure accelerated. The company's Photon 100 platform for silicon photonics and co-packaged optics testing could expand its addressable market by $300 million to $700 million annually over the medium term, according to company estimates. Teradyne also recently partnered with Tokyo Electron to develop a known good device screening test cell combining its UltraFLEXplus platform with TEL's Prexa SDP prober for chiplet-based 2.5D and 3D architectures.
The question is whether the rally has staying power. Earnings estimate revisions do not suggest further near-term strength, and the stock remains sensitive to macro crosscurrents — it gained 5.6% just six days earlier when Trump canceled planned military strikes on Iran, easing the rate-hike pressure that had compressed semiconductor valuations. Intel, the direct beneficiary of the Apple deal, was double-upgraded by Bank of America from underperform to buy with a $135 price target.
Teradyne competes with Applied Materials in the semiconductor equipment space. While Teradyne focuses on test and automation, Applied Materials specializes in wafer fabrication equipment. Applied Materials expects its packaging revenue to increase more than 50% in 2026 as chipmakers rely more heavily on 3D chiplet architectures and HBM integration, according to the company's fiscal second-quarter report. The broader equipment spending cycle is shifting toward leading-edge foundry-logic, DRAM and advanced packaging, which Applied Materials said would drive more than 80% of year-over-year wafer fab equipment growth in calendar 2026.
For investors, the Apple-Intel deal reinforces the US reshoring narrative for semiconductor manufacturing, which benefits equipment suppliers across the value chain. But Teradyne's elevated valuation leaves it exposed to any reversal in the rate outlook. The stock's 7.2% move on above-average volume indicates strong buying interest, but the absence of upward earnings estimate revisions suggests the market may need to see concrete order flow from the Intel-Apple partnership before assigning higher multiples. Teradyne trades in a sector where multiples compress when the risk-free rate rises, making any shift in Fed policy a key risk to monitor.
