Teradyne (TER) Q3 2025: AI-Driven Revenue Hits 50%, Reshaping Segment Mix for 2026
AI demand now drives over half of Teradyne’s revenue, accelerating a fundamental shift in business mix and capital allocation. Compute and memory test surged as hyperscaler and data center customers pulled in orders, while legacy mobile and robotics remained subdued. With AI-centric investments compounding, Teradyne signaled a heavier weighting toward compute in its 2026 and long-term model, setting up new competitive dynamics and margin structure for the coming year.
Summary
- AI Revenue Inflection: Over 50% of revenue in Q3, rising to 60% in Q4, now comes from AI-centric segments.
- Compute and Memory Outperformance: Data center and hyperscaler demand drove upside, while mobile and robotics lagged.
- 2026 Model Pivot: Long-term guidance will be more heavily weighted to compute and AI-driven memory, altering growth levers.
Performance Analysis
Teradyne’s Q3 saw a decisive shift as AI-related compute and memory test demand powered a sequential revenue increase and propelled earnings to the high end of guidance. Semiconductor test (semi-test) revenue reached $606 million, dominated by System-on-Chip (SOC) at $440 million, which was up double digits both sequentially and YoY. Memory test revenue more than doubled from Q2, with High Bandwidth Memory (HBM) and DRAM for AI applications representing the lion’s share, while flash remained weak, echoing industry TAM contraction.
Non-GAAP gross margin outperformed at 58.5% on favorable mix, but operating expenses climbed due to intensified R&D and go-to-market investments targeting AI, as well as higher variable compensation. Robotics revenue remained flat and well below prior-year levels, reflecting ongoing softness in indirect channels and a slow recovery from Q1’s trough. Free cash flow was modest, pressured by working capital tied to late-quarter sales and inventory build for upcoming AI-driven ramps.
- AI Mix Shift: AI-driven compute and memory now represent the majority of semi-test revenue, fundamentally changing segment composition.
- Legacy Segment Weakness: Mobile SOC and robotics continued to underperform, with only modest signs of improvement expected in 2026.
- Capital Return Acceleration: Share repurchases far exceeded free cash flow, signaling confidence in long-term AI-driven growth.
Overall, Q3 marked a turning point in Teradyne’s revenue mix and operational focus, setting the stage for a structurally different 2026.
Executive Commentary
"An example of this AI strength is in compute, where our view of the second half of 2025 revenue is more than 50% higher than our expectations just three months ago... As design process and packaging technologies for AI compute rapidly advance, we expect that our growth will continue."
Greg Smith, CEO
"In the second half of 2025, we're continuing to lean into R&D and go-to-market investments for AI opportunities that we expect will drive revenue in 2026 and beyond... At the midpoint of our Q4 guidance, we'll have full-year revenue growth of 9% and OpEx growth of 7%."

Strategic Positioning
1. AI-Centric Business Model Transformation
Teradyne’s business model is now anchored around AI data center buildout, with compute, networking, and memory test as the primary growth engines. The company’s Ultraflex Plus platform, designed for high-performance processors and networking, is seeing increased demand as chip complexity and test intensity rise. Design wins in HBM and system-level test (SLT) further cement Teradyne’s foothold in AI-driven workflows.
2. R&D and Capacity Investment
Focused R&D and applications engineering are driving product differentiation, especially for compute and HBM memory segments. Teradyne is expanding manufacturing capacity across multiple geographies to meet surging demand, while also investing in new features like singulated stack performance test for HBM4. These investments are expected to yield both near-term and multi-year returns as AI test needs accelerate.
3. Segment Realignment and Market Share Dynamics
Legacy mobile and robotics segments remain challenged, but AI-driven test is offsetting these headwinds. In memory test, Teradyne’s share is highest in DRAM/HBM final test but lower in wafer sort. The company expects overall memory revenue growth in 2026, but not necessarily share gains in expanding wafer sort SAM. Robotics growth is now tied to large customer and OEM channels, with AI-related robotics sales slowly increasing but still a small portion of total robotics revenue.
4. Capital Allocation and Financial Discipline
Teradyne accelerated buybacks and maintained dividends, returning $575 million to shareholders year-to-date—well above free cash flow. Management signaled continued balanced capital allocation, with OpEx growth targeted at half the rate of revenue growth in the long run, and near-term willingness to leverage the revolver to support working capital and capacity expansion.
5. Leadership Transition and Strategic Continuity
Incoming CFO Michelle Turner brings a mandate for growth and operational efficiency, as outgoing CFO Sanjay Mehta stays on as an advisor during the capacity ramp. The transition is framed as a continuation of Teradyne’s pivot to AI and disciplined capital deployment.
Key Considerations
Teradyne is navigating a structural pivot from legacy mobile and industrial test to AI-centric compute and memory test, with substantial implications for its revenue mix, margin profile, and competitive positioning.
Key Considerations:
- AI Test Intensity Rising: Chiplet-based designs and hyperscale data centers are driving higher test complexity and volume, increasing demand for Ultraflex Plus and Magnum platforms.
- Memory TAM Volatility: DRAM/HBM dominates, but flash remains depressed; 2026 could see flash uptick if mobile or SSD protocols shift.
- Seasonality and Lumpy Demand: Legacy mobile seasonality is fading, replaced by project-driven, volatile AI compute cycles that can swing quarterly results.
- Robotics Channel Shift: Indirect channel weakness persists, while large customer/OEM focus and AI-enabled robotics offer longer-term upside but remain nascent.
- Operational Leverage Commitment: Management reiterated the target of OpEx growth at half the rate of revenue, but near-term R&D and supply chain costs are elevated to capture AI opportunity.
Risks
AI-driven demand is highly concentrated among a few hyperscale customers, making Teradyne vulnerable to project timing shifts and purchasing cycles. Memory and compute test demand is inherently lumpy, and robotics recovery remains uncertain. Elevated OpEx and working capital needs could pressure margins if AI project ramps slow or macro volatility returns. Competitive dynamics in wafer sort and potential for share loss if new test insertions are not secured remain watchpoints.
Forward Outlook
For Q4 2025, Teradyne guided to:
- Sales between $920 million and $1 billion, reflecting continued AI project pull-ins.
- Gross margin of 57% to 58%, with temporary supply chain and capacity expansion costs offsetting volume leverage.
- OpEx at 31% to 33% of sales, as R&D and variable compensation remain elevated.
- Non-GAAP EPS between $1.20 and $1.46.
For full-year 2025, management expects:
- Revenue growth of 9% and OpEx growth of 7%.
Leadership highlighted:
- AI compute and memory as primary growth engines, with Q4 demand exceeding initial expectations.
- 2026 outlook stronger than six months ago, with AI and verticalization as key growth drivers and potential for legacy segment recovery.
Takeaways
Teradyne is now structurally an AI test company, with compute and memory test at the core of its growth and capital allocation strategy.
- AI Drives Mix and Margin: Over half of revenue now comes from AI, and this is expected to increase, altering business model economics and capital needs.
- Legacy Segments Still Weak: Mobile and robotics remain challenged, with only gradual improvement expected; AI must continue to deliver for guidance to hold.

Conclusion
Teradyne’s Q3 results and Q4 guidance confirm a rapid pivot to AI-centric demand as the dominant force in its business, with compute and memory test now the primary growth levers. The company’s investments in R&D, capacity, and go-to-market are paying off, but the future will be defined by the pace and concentration of AI-driven projects and the company’s ability to sustain operational leverage as the revenue mix evolves.
Industry Read-Through
Teradyne’s results reinforce that AI data center buildout is fundamentally reshaping the semiconductor test landscape, with demand for advanced compute and memory test outpacing legacy mobile and industrial applications. The shift away from consumer seasonality toward project-driven hyperscale cycles will likely become the new normal for test and automation peers. Robotics and industrial automation remain soft, suggesting that broader manufacturing recovery is still lagging the AI wave. Investors in semiconductor capital equipment and automation should expect continued volatility, with outsized opportunity for those positioned at the intersection of AI, compute, and advanced packaging.
