Teradyne, Inc., TER

Q4 revenue came in at $1.08B, crushing the consensus estimate of $969.33M. That represents a 44% increase compared to the same quarter last year. Non-GAAP earnings per share reached $1.80, beating analyst predictions of $1.36 by $0.44.

The performance reflected strength across the entire business. Semiconductor Test revenue hit $883M. Product Test generated $110M, while Robotics contributed $89M. All three segments showed sequential growth.

AI Testing Demand Fuels Growth

Artificial intelligence applications drove much of the quarter’s success. The company benefited from increased testing needs in compute, networking, and memory sectors tied to AI workloads.

Teradyne holds a strong position in the high-bandwidth memory testing market. The company currently commands roughly 50% of the HBM market share. Its new Magnum 7H system supports testing for HBM3E and HBM4, with upgrade capabilities for future generations.

Volume shipments of the Magnum 7H began in Q3 2025. The HBM testing market presents growing opportunities as memory requirements for AI applications become more complex.

Q1 Guidance Stuns Wall Street

The company’s first quarter outlook delivered another surprise. Teradyne expects Q1 revenue between $1.15B and $1.25B, far exceeding the $966.57M consensus estimate.

Non-GAAP earnings guidance for Q1 ranges from $1.89 to $2.25 per share. Analysts had anticipated just $1.25 per share. The midpoint of guidance represents a 61% beat over expectations.

Stock Performance and Analyst Views

The stock closed at $249.57 Monday before the pre-market surge. Over the past three months, shares gained 34.89%. The 12-month return stands at 124.66%.

Analyst sentiment improved following the report. The company received 16 positive EPS revisions in the last 90 days with zero negative revisions.

Green Mage Capital noted management’s 2028 targets of $8 to $9.50 EPS. At a 25x earnings multiple, the stock appears fairly valued but offers upside if growth accelerates.

Michael Del Monte highlighted the HBM opportunity. As testing complexity increases, Teradyne may expand its already substantial market share in this growing segment.

The company’s quant rating sits at Hold, with top marks for momentum and profitability metrics.
