On July 29, Teradyne rose 14.73% in regular trading, trading at $359.63/share, with turnover of $209 million. The surge was driven by the company's Q2 earnings report released after the prior session's close, which significantly exceeded market expectations.

Teradyne reported Q2 adjusted EPS of $2.47, far surpassing the analyst consensus of $2.09, representing a 333% increase from $0.57 a year earlier. Revenue reached $1.33 billion, up 104% year-over-year from $651.8 million, beating the expected $1.22 billion. Net income surged to $374.5 million from $78.4 million in the prior year. The semiconductor test segment contributed $1.122 billion, serving as the core growth engine fueled by AI chip testing demand and advanced packaging investments.

Q3 guidance was equally impressive, with projected adjusted EPS of $1.85 to $2.15 (midpoint $2.00) versus the $1.44 consensus, and revenue guidance of $1.2 billion to $1.3 billion, well above the Street estimate of $1.06 billion. Multiple investment banks including UBS, JPMorgan, and Goldman Sachs have recently raised price targets to the $450-$500 range.
