Last earnings call, Jul 28, 2026 AI summary
- What they said
- Teradyne reported a strong Q2 2026 with record revenue above $1.3 billion (up >100% YoY) and non-GAAP EPS of $2.47 (up >300% YoY), driven predominantly by AI-related demand. All three business groups (Semi Test, Product Test and Robotics) grew year-over-year, with Semi Test exceeding $1 billion and strong memory and compute performance. Management characterized this as the start of a multiyear growth phase supported by a widening ATE TAM tied to escalating WFE (wafer fab equipment) investment and data center build-out. Key areas of emphasis included compute (CPUs, accelerators, networking), memory (HBM and DDR), silicon photonics/CPO opportunities, and robotics tied to automation in electronics manufacturing and semiconductors. Management discussed TAM dynamics and WFE-to-ATE correlations (noting a rising share historically and expecting a stabilized test share in the 7%-9% range), competition and potential share gains over 2027, and gross margin variability driven by product mix, new product introductions, and memory-related margin pressure. Management also provided midterm expectations for growth, a wide CPO TAM range for 2028 ($300M–$700M) and reiterated the company’s positioning across multiple networking and silicon photonics modes.
- Guidance
- Q3 gross margin guidance of approximately 58%–59% (company expects full-year gross margin roughly ~59%). Management did not provide explicit revenue or EPS numeric guidance for Q3 on the call but signaled continued AI-driven growth into 2027 and midterm TAM expansion; CPO TAM estimated in a wide range ($300M–$700M in 2028) with a low-end near $200M–$300M next year in one scenario.
- Risks flagged
- Supply-chain fragility and single-supplier constraints (customers adopting dual-vendor strategies); gross margin pressure from memory products and pricing; timing/time-lag and variability in the correlation between WFE and ATE demand; competitive dynamics and China localization risks in certain end-markets; early-stage uncertainty in silicon photonics/CPO adoption (wide TAM range and execution risk). Also the usual forward-looking statement risks (see company's safe-harbor and 10-K).
