Additionally, Onto Innovation is scheduled to report earnings on May 5 after market close. Consensus estimates project quarterly revenue of approximately $292 million, representing a 9.68% year-over-year increase. However, adjusted earnings per share are expected to decline 3.44% year-over-year to approximately $1.42. Last quarter, the company posted revenue of $267 million with a net margin of 3.95% and adjusted EPS of $1.26, which reflected a 16.56% year-over-year decline. The anticipated earnings pressure may be amplifying near-term volatility as the report date approaches.
