    Executive summary

    Teradyne Q4 FY25 — AI-Driven Revenue Surges, New Target Model Unveiled

    Teradyne delivered a strong Q4 FY25, exceeding guidance with significant sequential growth driven by surging AI demand across its Semiconductor Test, Product Test, and Robotics segments. The company introduced a new evergreen target earnings model, projecting substantial revenue and EPS growth based on an expanded ATE TAM, reflecting confidence in AI's long-term impact despite near-term lumpiness and second-half visibility challenges.

    Highlights

    5

    • Q4 FY25 revenue of $1.083 billion exceeded high guidance, representing 41% sequential growth.

    • Q4 FY25 non-GAAP EPS of $1.80 was above high guidance, with over 100% sequential growth.

    • AI-driven revenue surged to over 60% of Q4 FY25 revenue, up from 40-50% in Q3 FY25, and is expected to reach 70% in Q1 FY26.

    • Full-year 2025 revenue grew 13% to $3.2 billion, with SoC and memory contributing a 17% year-over-year increase.

    • The new target earnings model projects approximately $6 billion in revenue and $9.50-$11 non-GAAP EPS at an ATE TAM of $12 billion-$14 billion.

    Concerns

    3

    • Forecasting SoC TAM is challenging due to high concentration and less predictable product ramps, where a single large socket can significantly impact year-to-year growth.

    • Uncertainty surrounds the 2026 mobile TAM, despite expected device complexity increases, due to questions about unit volume, product mix, and capital efficiency improvements.

    • Limited visibility into the second half of 2026 suggests that the strong Q1 performance might be part of a "2-, 3-quarter surge" potentially followed by a period of digestion.

    Questions about unit volume, product mix, and capital efficiency improvements.

    Second Half 2026 VisibilityH2 2026

    Limited visibility into the second half of 2026.

    Mitigation: Cautious guidance, expecting a potential 'shorter period of digestion' after Q1 strength.

    Lumpiness of Revenue

    Revenue will continue to be lumpy yet follow a less predictable pattern.

    Mitigation: New evergreen target earnings model designed to reflect this inherent lumpiness.

    Q&A highlights

    7

    How should we think about calendar 2026 revenue, particularly the H1/H2 weighting and overall growth rate, given the Q1 strength?

    Michelle Turner noted strong backlog and better H1 visibility for 2026, expecting sales to be 60% in H1 and 40% in H2 (inverse of 2025). Greg Smith cautioned that Q1 strength might be a 2-3 quarter surge leading to digestion, and H2 visibility is limited, making full-year linearity unpredictable.

    “The run rate that we have in Q1 is like we have a fair amount of strength in Q1. We don't have great visibility into the second half. So we're a little bit cautious that we don't want people to sort of take that and run with it for the full year. We expect that we're in kind of a 2-, 3-quarter surge that may lead to a shorter period of digestion afterwards.”

    Detailed Narrative

    01

    AI-Driven Demand Surge

    Teradyne experienced a significant surge in AI-driven revenue, accounting for over 60% of Q4 FY25 revenue, a notable increase from 40-50% in Q3 FY25. This trend is expected to continue, with AI applications projected to drive upwards of 70% of Q1 FY26 revenue. This robust demand spans various segments including compute, memory, power management, SLT, HDD, ICT, and optical test, aligning with the company's strategic themes of AI, verticalization, and electrification.

    02

    Strategic Pivot to Compute

    The company has successfully pivoted its business mix, with compute becoming the largest component of its SoC revenue in 2025, growing 90% year-over-year. This marks a significant shift from 2023, when compute represented only about 10% of SoC product revenue, while auto/industrial and mobile each comprised roughly 25%. This rebalancing has enabled the capture of valuable new design wins and is seen as a strategy to derisk the target earnings model by diversifying away from historical mobile dominance.

    03

    Memory Market Resurgence and Share Gains

    The memory test market saw a significant shift in 2025, with DRAM and HBM comprising nearly 90% of the memory TAM, a substantial change from 2020-2021 when FLASH and DRAM were more evenly split. Teradyne expects a resurgent memory market in 2026 with low double-digit TAM growth over 2025, driven by continued strength in HBM and DRAM. The company anticipates continuing its incremental share gains in this market, building on its performance in 2025 where it gained share in a roughly flat market.

    04

    IST Expansion and Diversification

    The Instrument Systems Test (IST) business delivered over 50% growth from 2024 to 2025, driven by successful diversification beyond its historical concentration. This expansion includes winning a new customer in mobile SLT in 2024, entering compute SLT with two new customers in 2025, and securing orders from a new HDD customer in late 2025, expected to ramp in 2026. This broader customer base and segment entry are setting up IST for continued strong revenue growth in 2026 and beyond.

    05

    New Evergreen Target Earnings Model

    Teradyne introduced an evergreen target earnings model, framing its P&L around an ATE TAM of $12 billion to $14 billion, which is a significant increase from $9 billion in 2025 and is believed to be achievable within the midterm. This model projects roughly $6 billion in revenue, gross margins between 59% and 61%, OpEx of 27-29% of revenue, operating profit of 30-34%, and non-GAAP EPS of $9.50-$11. This approach reflects confidence in the long-term growth potential of the ATE TAM driven by AI, while acknowledging the inherent lumpiness of demand.

    06

    MultiLane Joint Venture for AI Data Center Market

    In alignment with its strategy to serve the AI data center market from wafer to data center, Teradyne announced an agreement with MultiLane to form a joint venture called MultiLane Test Products. MultiLane is a global leader in high-speed I/O and data center interconnect test solutions. Teradyne will be the majority owner, with the transaction expected to close in the first half of 2026. This deal is anticipated to be accretive to EPS in 2026, albeit with a de minimis impact.
