Teradyne (TER), a leading manufacturer of testing equipment for semiconductors and electronics, experienced a significant 17% drop in its stock price, making it the biggest loser on the S&P 500 on Tuesday. This decline followed the company’s updated guidance, reflecting concerns about the potential impact of new tariffs and trade restrictions.
In a presentation preceding its Investor Day, Teradyne acknowledged anticipating short-term volatility, primarily within its SemiTest business. The company cited new uncertainties surrounding tariffs and trade restrictions as the main contributors to this volatility. While Teradyne doesn’t foresee order cancellations, it does expect some project postponements and capital expenditure reviews.
For the current quarter, Teradyne maintains its existing outlook. However, the company projects second-quarter revenue to be flat or potentially decline by up to 10% compared to the first quarter. Despite this, Teradyne anticipates a 5% to 10% year-over-year increase in full-year revenue. Looking further ahead to fiscal 2026, the company predicts that both earnings per share (EPS) and revenue will trend toward the lower end of its previous 2026 financial model.
Simultaneously with the guidance update, Teradyne announced the acquisition of Quantifi Photonics, a privately held company specializing in photonic integrated circuit testing devices. The acquisition price remains undisclosed. This strategic move expands Teradyne’s capabilities in the rapidly growing photonics market.
Before Tuesday’s decline, Teradyne’s stock price had remained relatively stable over the past year. However, the recent drop brought the stock to its lowest point in approximately a year and a half, reflecting investor concern over the potential impact of trade tensions on the company’s future performance. The acquisition of Quantifi Photonics, while potentially beneficial in the long term, did little to offset the negative impact of the revised guidance.

In conclusion, Teradyne’s updated guidance, driven by concerns over tariffs and trade restrictions, led to a substantial decline in its stock price. While the company anticipates continued revenue growth in the current fiscal year, the long-term outlook for 2026 appears less optimistic. The acquisition of Quantifi Photonics positions Teradyne for future growth in the photonics sector, but the immediate impact of trade uncertainties remains a significant concern for investors.
