On June 6, Onto Innovation fell 5.2% in regular trading, trading at $259.74/share, with trading volume of $104 million.

On the news front, the company's previously announced $1.1 billion convertible senior notes offering continues to weigh on shares. The initial announcement triggered a sharp decline of over 15%, and while Oppenheimer subsequently published a report arguing the pullback was primarily driven by convertible-related hedging activity and highlighted an attractive buying opportunity, dilution concerns have not been fully absorbed. The stock briefly recovered but has resumed its downward trajectory.

Meanwhile, the broader semiconductor equipment sector experienced a deep correction on the same day. Among sector peers, Teradyne fell 8.14%, KLA-Tencor fell 6.26%, Applied Materials fell 6.21%, Lam Research fell 6.19%, and ASML Holding fell 4.69%, with sector-wide selling pressure further amplifying downside momentum for Onto Innovation.
