Teradyne (TER) Q4 2025: AI Drives 60%+ of Revenue, Reshaping Segment Mix and Earnings Model
AI-centric demand fundamentally shifted Teradyne’s revenue base, segment weighting, and long-term model in Q4 2025. The company’s results outpaced guidance, with AI now accounting for over 60% of revenue and a new evergreen target model anchored in a $12–14 billion ATE market. Management signals robust first-half 2026 momentum, but flags lumpiness and limited second-half visibility as AI infrastructure cycles evolve.
Summary
- AI-Driven Revenue Transformation: Over 60% of Q4 revenue now tied to AI, fundamentally shifting business mix.
- Segment Rebalancing Accelerates: Compute becomes largest SOC driver, with mobile and auto/industrial each now at a quarter share.
- Evergreen Earnings Model Debuts: New target model pivots to midterm ATE TAM, not fixed years, reflecting market unpredictability.
Performance Analysis
Teradyne delivered a standout Q4, with revenue and non-GAAP EPS both exceeding the top end of guidance, fueled by a surge in AI-related demand. The company saw 41% sequential revenue growth and more than doubled non-GAAP earnings from Q3, with every major business—semiconductor test, product test, and robotics—posting double-digit sequential gains. Semiconductor test revenue, led by AI compute and memory, was the primary engine, supported by robust SOC (system-on-chip) and record memory sales. Robotics revenue rose for a third straight quarter, propelled by a large e-commerce customer ramping AI-driven automation deployments.
AI’s influence is now unmistakable: In Q4, more than 60% of total revenue was AI-driven, up from 40–50% in Q3, and management expects this figure to climb to 70% in Q1 2026. The company’s revenue mix has migrated away from its historical mobile-centric base to a more balanced portfolio, with compute now making up nearly half of SOC revenue. Product test and robotics also delivered strong growth, with new customer wins and expanded applications in defense, aerospace, and logistics. Free cash flow remained robust, enabling $204 million in shareholder returns via buybacks and dividends in the quarter. Gross margins were stable, with strong semi-test performance offset by lower margins in product test and robotics, and a legacy inventory write-down.
- AI Demand Surges: AI now drives the majority of revenue, reshaping demand patterns, segment mix, and capital allocation.
- Segmental Growth Divergence: Compute SOC grew 90% YoY, while memory test and robotics posted record and multi-quarter gains, respectively.
- Cash Flow Enables Shareholder Returns: Free cash flow and disciplined capital allocation supported aggressive buybacks and dividends.
Teradyne’s Q4 marks a strategic inflection, with AI not only boosting top-line results but also catalyzing a reconfiguration of the company’s portfolio and earnings model. The shift from mobile to compute as the dominant SOC driver de-risks future earnings, but also introduces new lumpiness as AI infrastructure cycles replace historical seasonality.
Executive Commentary
"A striking trend was the increase in AI-driven revenue in the second half of 2025. This is obvious in computing memory. However, the rapid build-out of cloud and edge AI is also driving demand for power management, SLT, HDD, ICT, and optical test. This aligns with the themes of AI, verticalization, and electrification that we have highlighted in prior calls. When you roll it up, AI demand drove 40% to 50% of our revenue in Q3. In Q4, AI drove more than 60% of our revenue. Looking forward to Q1 of 2026, we expect that upwards of 70% of our revenue will be driven by AI applications."
Greg, President and Chief Executive Officer
"Fourth quarter sales were $1.83 billion with non-GAAP EPS of $1.80, both above the high end of our guidance range. Fourth quarter sales were the highest revenue quarter of 2025 and our second highest quarter in history... The product test group at $110 million grew double digits sequentially and year-on-year, driven by strong defense and aerospace demand. Robotics revenue of $89 million grew for the third consecutive quarter and was up 19% from Q3. In Q4, greater than 5% of our robotics revenue was driven by a large e-commerce customer."

Strategic Positioning
1. AI-Centric Portfolio Realignment
Teradyne’s business model has pivoted decisively toward AI infrastructure. Compute now comprises nearly half of SOC revenue, up from just 10% in 2023, while mobile and auto/industrial have each receded to roughly a quarter share. This diversification reduces exposure to mobile cyclicality, with AI data center and edge deployments driving both compute and memory test demand. The company’s roadmap now targets the full AI stack, from device and board test to robotics in data center operations.
2. Evergreen Earnings Model Anchored in $12–14B ATE TAM
Management abandoned year-specific targets, adopting a model tied to ATE TAM (Automated Test Equipment Total Addressable Market), which is projected to grow from $9B in 2025 to $12–14B in the midterm. The new model targets $6B in revenue, 59–61% gross margins, and $9.50–$11 non-GAAP EPS at scale, reflecting confidence in AI-driven secular growth but acknowledging market lumpiness and timing uncertainty.
3. Segmental Growth and Share Gain Opportunities
Teradyne expects to outgrow the ATE market in semi-test, led by AI compute and memory share gains, while also driving incremental growth in product test (defense, photonics, high-speed data) and robotics (physical AI, e-commerce automation). The newly announced Multilane joint venture expands its reach in data center interconnect test, further embedding Teradyne in the AI infrastructure build-out.
4. Robotics Scaling and E-Commerce Tailwind
Robotics revenue growth is accelerating, with a major e-commerce customer ramping deployments that are expected to triple revenue from this account in 2026. Management aims for robotics to reach breakeven this year, with positive contribution beyond as AI-driven warehouse and logistics automation scales globally.
5. Capital Allocation and M&A Flexibility
Teradyne maintains a disciplined capital allocation strategy, returning nearly all free cash flow to shareholders while preserving dry powder for opportunistic M&A. The company’s approach is to balance shareholder returns with investments in growth platforms and adjacencies, as evidenced by recent acquisitions and joint ventures to expand TAM and capture emerging AI opportunities.
Key Considerations
Teradyne’s Q4 and full-year results mark a structural shift in the company’s growth drivers, risk profile, and operational cadence. Investors should recalibrate expectations for seasonality, margin structure, and segmental leadership as AI transforms the business.
Key Considerations:
- AI Infrastructure Cycles Supplant Seasonality: Traditional mobile-driven Q2/Q3 peaks have given way to unpredictable, AI-driven demand surges, with 2026 sales expected to be first-half weighted.
- Customer Concentration Remains Material: Two specifying and one purchasing customer each contributed over 10% of 2025 revenue, underscoring ongoing lumpiness and exposure to large program ramps.
- Compute and Memory Test TAM Expansion: Compute TAM reached $5B in 2025, with memory TAM at $1.4B (dominated by DRAM/HBM); both are set for robust growth, but forecasting remains challenged by program timing and hyperscaler buying patterns.
- Robotics and Product Test Diversification: New e-commerce and defense wins de-risk the portfolio, but these segments remain smaller contributors versus semi-test.
- Capital Returns Balanced with Growth Investment: High free cash flow supports both aggressive shareholder returns and strategic M&A, such as the Multilane JV and photonics acquisitions.
Risks
Visibility beyond the first half of 2026 is limited, with management warning against extrapolating current run rates due to the “lumpiness” of AI infrastructure build-outs and concentrated customer programs. Customer concentration, unpredictable program ramps, and potential moderation in AI data center growth are key risks, as is the competitive intensity in compute and GPU test share. Capital efficiency improvements by customers could also dampen incremental tester demand even as device complexity rises.
Forward Outlook
For Q1 2026, Teradyne guided to:
- Revenue of $1.15B–$1.25B, a new quarterly record, driven by AI demand
- Non-GAAP EPS of $1.89–$2.25
- Gross margins of 58.5–59.5%
- Operating profit rate at 32% midpoint
For full-year 2026, management did not provide explicit guidance, but expects:
- Sales to be first-half weighted (60% H1, 40% H2), the inverse of 2025
- ATE TAM growth in the 20–40% range, but with wide uncertainty for H2
Management highlighted the following:
- Strong backlog and improved first-half visibility compared to prior years
- Second-half demand highly uncertain, with potential digestion period post-surge
Takeaways
Teradyne’s Q4 2025 results underscore a paradigm shift: AI is now the central force shaping revenue, segment mix, and long-term strategy.
- AI Demand Reshapes Business: Compute overtakes mobile as the dominant SOC driver, de-risking earnings but introducing new cyclicality tied to hyperscaler and data center build cycles.
- Evergreen Model Reflects Market Realities: The move to an ATE TAM-anchored model signals management’s recognition that year-specific targets are obsolete in a volatile, AI-driven market.
- Visibility and Lumpy Revenue Patterns Remain: Investors should expect continued unpredictability, with first-half surges and potential second-half slowdowns as AI infrastructure cycles evolve.
Conclusion
Q4 2025 marked a structural inflection for Teradyne, with AI demand now driving the majority of revenue and a new, more resilient segment mix. While the company is well-positioned for share gains and TAM expansion, investors must weigh the benefits of AI-driven growth against the risks of market lumpiness and concentrated customer exposure.
Industry Read-Through
Teradyne’s results are a clear signal that AI infrastructure build-outs are fundamentally altering demand patterns in semiconductor capital equipment and adjacent test markets. The migration from mobile to compute as the dominant revenue driver, and the growing importance of AI-centric test capabilities, will likely ripple across the supply chain, benefiting those with exposure to high-complexity, high-volume compute and memory test. Vendors with flexible, AI-optimized platforms and diversified customer bases are best positioned to capture share as hyperscaler and data center cycles drive new waves of capital investment. However, all players must navigate increased lumpiness, customer concentration, and the risk that AI build cycles moderate as infrastructure matures.
