    Executive summary

    Teradyne Q3 FY25 — AI-Driven Semiconductor Test Fuels Strong Growth

    Teradyne's Q3 FY25 performance was significantly boosted by robust AI-driven demand in Semiconductor Test, particularly for compute and memory, leading to strong sequential revenue and EPS growth. The company anticipates this AI momentum to continue, driving solid growth into 2026, despite ongoing softness in robotics, mobile, and auto industrial markets. Management is strategically investing in R&D and capacity to capitalize on these AI opportunities, which are also influencing a shift in the business's seasonality.

    Risks & headwinds

    5
    Robotics Market WeaknessQ3 FY25

    Robotics revenue flat quarter-on-quarter at $75 million and down year-over-year in Q3 FY25.

    Mitigation: Expanding large customer and OEM channels; leveraging AI features for AMRs and UR cobots.

    Mobile and Auto Industrial Market WeaknessQ3 FY25

    Conditions in mobile and auto industrial remained somewhat weak.

    Mitigation: Anticipate business conditions will improve, but timing and intensity of recovery are uncertain.

    Memory TAM DeclineFY25

    Total memory TAM for 2025 will be down low double digits, with flash being the weakest part.

    Mitigation: Memory revenue expected to sustain at 2024 levels despite TAM decline, driven by HBM and AI-related LPDDR demand.

    Lumpy Shipments in AI MarketOngoing

    Timing of any one project can affect the delivery schedule for hundreds of testers, swinging quarterly results significantly.

    Mitigation: Investing in R&D, applications, sales, support, and manufacturing capacity for expansion; expediting supply chain and accelerating production capacity.

    One-time Supply CostsQ4 FY25

    Some one-time supply costs in Q4 FY25 to meet accelerated demand, impacting gross margin.

    Mitigation: Expediting supply chain and accelerating production capacity growth at factories in multiple geographies.

    What to watch in Q4 FY25

    5

    Mobile SoC demand

    2026
    Currentpretty low level for the past couple of years
    Targetbigger than it is this year

    Why it matters

    A significant upward inflection in handset sales is the 'big X factor' for mobile TAM and overall revenue, influencing the magnitude of recovery.

    Looking forward to next year, we don't know. I think the honest answer is we don't know exactly how big it would be. We're optimistic that it should be bigger than it is this year, but we're unsure of the magnitude of that.

    Q&A highlights

    6

    What are the main drivers of the Q4 upside, and how do chiplet designs and dual sourcing impact long-term compute test intensity?

    Q4 upside is primarily 2/3 from compute and networking and 1/3 from memory, with HBM being a strong contributor. Compute test intensity is expected to grow due to larger die sizes, higher performance requirements, escalating scrap costs with chiplet designs, and low tolerance for latent defects in data centers. The trend of dual sourcing in the primary semiconductor driver market is also favorable for Teradyne.

    “The other thing that's happened in compute is that because it's now the primary driver for the semiconductor industry that many of the strategies that we've seen in the mobile space for years and years around things like dual sourcing, are becoming much more important to the producers in this space.”

    Detailed Narrative

    01

    AI-Driven Semiconductor Test Dominance

    Teradyne's Q3 performance was significantly propelled by AI demand in Semiconductor Test, with compute and memory test sales seeing substantial increases. The company's UltraFLEXplus system is architected for high-performance processors and networking devices, which have demanding power, pin count, and test data requirements. The Magnum 7H product supports HBM performance test across multiple generations, including HBM3E, HBM4, HBM4E, and HBM5, and began volume shipments for HBM singulated stack performance test in Q3.

    02

    Strategic Investments and Market Alignment

    Teradyne is making focused R&D investments in compute test, yielding new differentiated capabilities, and expanding engineering teams to help customers develop and ramp production of complex AI devices. These investments are expected to drive growth in 2026 and beyond, aligning the company with the primary demand driver of AI data center investments. Management noted that the returns on these investments are well worth the cost, as evidenced by the strong Q3 results and Q4 guidance.

    03

    Robotics and Other Businesses Performance

    Robotics continues a slow recovery from its Q1 trough, with persistent weakness in the core indirect distribution channel. However, the company is expanding its large customer and OEM channels, and AI-related products accounted for over 8% of robotics sales in Q3, up from 6% in Q2. Service revenue also increased to 14% of sales, up from 12% in Q2, reflecting an important element of the robotics strategy to deliver value-added service to its installed base of over 100,000 robots.

    04

    Shift in End-Market Dynamics and Seasonality

    The Semi Test business has evolved, with AI data center investments now being the largest demand driver, replacing consumer end markets. This shift is expected to change the seasonality of Teradyne's business, moving away from mobile launch-driven demand to more lumpy, customer launch-driven compute projects. The company noted that projects are accelerating into Q4, reflecting customers' drive to pull AI projects in from Q1, and they are expediting the supply chain and accelerating production capacity.

    05

    2026 Outlook and Long-Term Model

    Management expects 2026 to be a year of solid growth, driven primarily by AI and verticalization. While mobile, auto industrial, and robotics are anticipated to improve, the timing and intensity of their recovery remain uncertain. The long-term model will be updated in January, with a heavier weighting on AI-driven compute and memory markets, as massive investments in data centers translate into strong demand for UltraFLEXplus and Magnum products.

    06

    CFO Transition

    Michelle Turner will become Chief Financial Officer effective November 3, 2025. She brings 30 years of financial and strategic leadership experience in the technology and manufacturing sectors. Outgoing CFO Sanjay Mehta will remain as an executive advisor to operations, focusing on capacity expansion in 2026, and was thanked for his excellent leadership and contributions over the past six years.
