Quarterly figures show solid top-line growth

On the fundamental side, Onto Innovation’s most recent reported numbers come from the first quarter of 2026. According to a summary of the company’s filings and releases compiled by Stock Titan, Onto Innovation reported first quarter 2026 revenue of USD 291.9 million, representing a 9.5 percent increase year over year. The same overview notes that, despite the top-line growth, GAAP net income for the quarter declined to USD 33.8 million, with diluted earnings per share falling to USD 0.67 from USD 1.30 a year earlier, while GAAP gross margin came in at 50.1 percent.

On a non-GAAP basis, Onto Innovation generated operating income of USD 77.9 million and diluted earnings per share of USD 1.42 in the first quarter of 2026, according to the data cited by Stock Titan. Looking ahead, the company guided revenue for the second quarter of 2026 to a range of USD 320 million to USD 330 million, with non-GAAP diluted EPS projected between USD 1.65 and USD 1.73. That revenue outlook represents an increase of roughly 9.7 percent to 13.1 percent relative to the first quarter 2026 revenue of USD 291.9 million, and the implied non-GAAP EPS range suggests further earnings expansion if the company executes on its guidance.

The same filing overview indicates that Onto Innovation had earlier provided guidance for first quarter 2026 revenue between USD 275 million and USD 285 million, with non-GAAP diluted EPS expected in a range of USD 1.26 to USD 1.36 and a non-GAAP operating margin between 25.5 percent and 26.5 percent. In a preliminary update, Onto Innovation later signaled that first quarter 2026 revenue would be approximately USD 292 million, above the high end of that original revenue guidance range of USD 285 million, as noted by Stock Titan. For investors, the fact that revenue ultimately exceeded the previously communicated outlook while margins and GAAP earnings showed some pressure underscores the importance of monitoring how product mix and cost structure affect profitability over the coming quarters.

Events and valuation considerations

The investor calendar compiled by MarketBeat lists Onto Innovation’s last earnings release as having occurred on August 6, 2026 and indicates an estimated next earnings date of November 5, 2026, with a dedicated investor day scheduled for December 17, 2026. While the November 5, 2026 date is flagged as an estimate rather than a formally confirmed schedule, it provides a working timeframe for when the company is expected to update the market on its second quarter performance and outlook.

At recent prices around the mid-USD 260s, Onto Innovation’s market capitalization stands in the multibillion-dollar range, reflecting its role as a mid-cap player in the semiconductor capital equipment space, though precise market-capitalization figures are not detailed in the available summaries. The combination of a high earnings multiple, robust expected EPS growth of 45.77 percent in the coming year and a consensus price target of USD 378.00 suggests that investors are betting on sustained demand for the company’s inspection and metrology tools as chipmakers invest in advanced nodes and new production capacity.
