On July 30, Teradyne rose 6.44% in after-hours trading, trading at $315.65/share, with turnover of $3.7023 million.

The rally was driven by the company's Q2 earnings report released earlier, which significantly exceeded market expectations. Q2 adjusted EPS came in at $2.47, well above the consensus estimate of $2.09, while revenue reached $1.33 billion, up 104% year-over-year and surpassing the expected $1.22 billion. The semiconductor test segment contributed $1.122 billion, powered by AI chip testing demand. Net income surged to $374.5 million from $78.4 million a year earlier.

Q3 guidance was equally strong, with projected adjusted EPS of $1.85 to $2.15 (midpoint $2.00) far exceeding the analyst consensus of $1.44, and revenue guidance of $1.2 to $1.3 billion well above the $1.06 billion estimate. Multiple investment banks have raised price targets, with Cantor Fitzgerald lifting its target to $550 from $400, while UBS, JPMorgan, and Goldman Sachs set targets between $450 and $500.
