AI Demand Fuels Semiconductor Test Segment Growth

Revenue increased 104% year over year, while adjusted earnings rose more than 300%, marking the second consecutive record for revenue and exceeding the high end of the company's own guidance 1

1

. The Semiconductor Test segment generated $1.122 billion in revenue during the quarter, representing a 128% jump and driving the majority of growth 3

3

. Teradyne is benefiting directly from rising technology content in AI-driven chips, as the architectures used in data centers require more computing power, memory, and reliability 3

3

. As components become more complex and expensive, manufacturers multiply inspection steps, enabling test equipment to gain value within the production chain.

Strong AI-Related Demand Extends Beyond Advanced Processors

Chief Executive Officer Greg Smith said strong demand across semiconductor test and Robotics, particularly AI-related opportunities spanning wafer production to data centers, drove another record quarter 1

. The company also reported record memory revenue, driven by sustained DRAM and NAND demand and a recovery in NAND final test activity 1

1

. This broadening beyond the most advanced processors suggests AI is filling order book across multiple segments, as the buildout of AI-driven infrastructure investments pulls storage and memory needs along with it 3

Robotics and Product Test Add Diversified Revenue Streams

Product Test contributed $107 million in revenue, up 25%, while Robotics added $100 million, representing 33% year-over-year growth driven by deployments with major e-commerce customers 3

3

. These divisions remain overshadowed by semiconductors but provide a revenue base less dependent on hyperscaler-driven demand from a handful of massive programs 3

3

. Cash generation confirms the quality of the quarter, with free cash flow reaching $378 million versus $132 million a year earlier, providing substantial resources to fund R&D spending and continue share buybacks 3

Bullish Outlook for Q3 Exceeds Expectations Despite Sequential Moderation

For the third quarter, Teradyne expects adjusted earnings of $1.85 to $2.15 per share, above the analyst consensus estimate of $1.53, while forecasting revenue of $1.20 billion to $1.30 billion, exceeding the consensus estimate of $1.042 billion 1

1

. Management guided Q3 2026 EPS to a range well above Street consensus, with CEO Greg Smith stating the bullish outlook "reflects robust AI-related demand" 2

2

. Smith added that near-term AI demand remains robust, while higher investments in wafer fabrication equipment are expected to support growth beyond 2027 1

1

. However, the midpoint implies a sequential decline of roughly 6% in revenue and nearly 19% in earnings per share, marking the end of a run of sequential accelerations 3

3

. Investors should watch whether orders remain concentrated and sensitive to investment timing from a small number of customers, even as the year-over-year comparisons remain impressive.
