Teradyne’s shares tumbled 19.4% following its Q1 2026 results on Apr. 28 as investors focused on the company’s softer-than-expected outlook and margin concerns rather than the strong quarter. While Q1 revenue surged 87% year-over-year to $1.282 billion and adjusted EPS jumped to $2.56, Q2 guidance called for revenue of only $1.15 billion – $1.25 billion (midpoint $1.20 billion) and implied gross margins of about 57.5%, down roughly 350 basis points sequentially.
Analysts noted that the guidance did not fully reflect the strong AI-driven demand that generated approximately 70% of Q1 revenue, leading investors to worry about growth in the second half of 2026 despite management’s positive outlook and analysts maintaining bullish ratings.
In comparison, rival Applied Materials, Inc. (AMAT) has outpaced TER stock on a YTD basis, with AMAT shares increasing 128.7%. However, AMAT stock has gained 244.5% over the past 52 weeks, lagging behind TER stock.
