TER Benefits From Expanding Memory Test Portfolio
Teradyne is benefiting from rising demand for advanced memory testing, supported by strong high-bandwidth memory (HBM), DRAM and NAND requirements tied to artificial intelligence (AI) infrastructure. The company’s expanding memory test portfolio, led by Magnum platforms, has been noteworthy. It highlighted that Magnum testers combine memory and logic-test capabilities, providing memory manufacturers with attractive swing-tool flexibility.
Memory has emerged as an important growth engine for Teradyne. In the second quarter of 2026, memory revenues reached a record $212 million, marking the third consecutive quarter above $200 million. Growth was driven by robust demand for HBM and DRAM test solutions, as well as a recovery in NAND. Memory book-to-bill exceeded 2, indicating solid demand visibility. Management expects the 2026 memory test TAM to be more than 40% higher than 2025, supported by HBM, DRAM and NAND growth.
Further expanding its memory test portfolio, Teradyne recently launched Magnum E2, a next-generation high-speed memory test system designed to address growing test requirements driven by artificial intelligence and high-performance computing. Built on the company’s Near-DUT Test architecture, Magnum E2 supports advanced DRAM and flash interfaces, including LPDDR6, DDR6, GDDR7 and NAND flash. The platform offers higher parallelism, improved signal integrity and support for NRZ, PAM3 and PAM4 signaling. It also combines memory and logic testing on a single platform, helping manufacturers simplify testing while supporting qualification through high-volume production.
Rising memory bit production and technology transitions such as HBM3 to HBM4, DDR5 to DDR6, and next-generation flash should further increase test requirements, supporting Teradyne’s ability to expand its memory-testing footprint. Management expects memory revenues to grow in the second half compared to the first half.
TER Initiates Positive Q3 Guidance
Teradyne’s expanding portfolio and strong demand for AI-related applications are expected to drive the company’s top-line growth.
For the third quarter of 2026, Teradyne expects revenues in the range of $1.20-$1.30 billion. The Zacks Consensus Estimate for third-quarter 2026 revenues is pegged at $1.27 billion, suggesting a 65.20% year-over-year increase.
For the third quarter, the company’s non-GAAP earnings are expected to be between $1.85 and $2.15 per share. The consensus mark for earnings is pegged at $2.04 per share, which has been unchanged over the past 30 days. This indicates growth of 140% on a year-over-year basis.
Despite expanding portfolio and strong demand for AI-related applications, the company suffers from stiff competition in the AI infrastructure space from companies like Cohu (COHU - Free Report) . The company is also suffering from customer concentration, program timing, muted mobile demand, memory-driven margin dilution, higher operating spending and currency exposure.
Cohu’s improving semiconductor test demand and expanding exposure to AI computing, HBM inspection and software remain noteworthy. Growth in AI workloads is driving demand for HBM, and Cohu has established a position in this market through its Neon inspection platform. Cohu is extending its Neon inspection platform across HBM3, HBM4 and HBM4E production while investing in HBM5 and later generations.
