On July 29, Teradyne rose 11.96% overnight, trading at $360.04/share, with turnover of $30,100. The surge was driven by the company's Q2 earnings report released after the prior session's close, which significantly exceeded analyst expectations across all key metrics.

Teradyne reported Q2 adjusted EPS of $2.47, beating the consensus estimate of $2.09 by 18.18%, representing a 333% increase from $0.57 per share in the year-ago period. Revenue reached $1.329 billion, surpassing the $1.223 billion estimate and more than doubling from $651.8 million a year earlier. The semiconductor test segment contributed $1.122 billion, with system test at $107 million and robotics at $100 million.

The company issued Q3 guidance of $1.85 to $2.15 in adjusted EPS on revenue of $1.20 billion to $1.30 billion, far exceeding analyst expectations of $1.56 EPS on $1.06 billion in revenue. The stock had declined nearly 7% during the prior regular session amid broad semiconductor equipment sector selling pressure, but reversed sharply on the strong results. UBS, JPMorgan, and Goldman Sachs have recently raised target prices to the $450-$500 range.
