Onto Innovation Signals Record Quarter on Surging AI Demand

WILMINGTON, Mass. – April 16, 2026 – Onto Innovation Inc. (NYSE: ONTO) is poised to deliver a blockbuster first quarter, driven by an intense, industry-wide surge in demand for artificial intelligence infrastructure. The semiconductor equipment manufacturer today announced preliminary first-quarter revenue of approximately $292 million, a figure that dramatically surpasses both its own prior guidance and prevailing Wall Street expectations.

The updated forecast, released just weeks before its official earnings announcement scheduled for May 5, 2026, significantly outpaces the company's initial projection of $275 million to $285 million. This bullish signal was further amplified by a newly issued revenue outlook for the second quarter of $320 million to $330 million, suggesting accelerating momentum into the summer. Investors and analysts, who had pegged Q1 consensus revenue closer to $280 million, are now recalibrating their models for a company firing on all cylinders.

The upcoming conference call on May 5, to be hosted by CEO Michael P. Plisinski and CFO Brian Roberts, has transformed from a routine financial update into a highly anticipated event. Stakeholders will be keen to unpack the drivers behind the outperformance and understand the sustainability of this growth trajectory.

Riding the AI and Advanced Packaging Wave

The semiconductor industry is in the midst of a powerful upcycle, and Onto Innovation appears to be a key beneficiary. The primary engine of this growth is the global rush to build out AI capabilities, which requires a new generation of powerful, complex microchips. This trend is fueling massive investment in leading-edge logic, high-bandwidth memory (HBM), and, critically, the advanced packaging techniques needed to assemble these components into functional systems.

Onto Innovation's specialization in process control—the metrology and inspection tools that ensure quality and yield in chip manufacturing—places it directly in the critical path of this expansion. The company’s technologies are essential for producing the complex, multi-layered chip packages that AI systems demand. According to recent industry reports, the global market for semiconductor manufacturing equipment is projected to soar to a record $133 billion in 2025 and continue climbing to $156 billion by 2027, with AI-related spending leading the charge.

Management has explicitly tied its recent success to this trend. The company's new Dragonfly® G5 inspection platform was recently qualified by a major customer for 2.5D advanced AI packaging, with initial shipments slated for June. This technology is vital for inspecting the intricate connections in chiplet-based designs, a cornerstone of modern AI hardware. The company projects that demand for its Dragonfly platform family will grow by more than 50% in 2026 compared to the previous year, positioning it as a significant revenue driver.

A Strong Start After a Resilient 2025

Onto Innovation's explosive start to 2026 comes on the heels of a resilient performance in 2025, a year that saw the company navigate market fluctuations to ultimately achieve record results. The company crossed the $1 billion revenue threshold for the full year, a significant milestone.

The year began with a strong first quarter, where revenue climbed 17% year-over-year to $267 million. However, the company experienced a softer period mid-year, with Q2 and Q3 revenues showing a sequential decline, reflecting broader market adjustments at the time. A robust recovery in the fourth quarter, which saw revenue rebound to nearly $267 million, set the stage for the current period of accelerated growth.

This historical performance demonstrates the company's ability to manage market cycles while executing on long-term strategic initiatives. The strong finish to 2025, combined with the powerful industry tailwinds from AI, has created a foundation for the exceptional results now being signaled for 2026.

Strategic Wins and a Competitive Landscape

The company's success is not merely a matter of being in the right market at the right time. Strategic execution has been pivotal. During its Q4 2025 earnings call, management highlighted the closing of a landmark volume purchase agreement estimated at over $240 million with a leading HBM manufacturer. The deal, which leverages Onto's Dragonfly® 2D inspection and 3D bump metrology, is set to support the customer's expansion plans through 2027 and serves as a powerful validation of its technology in a high-growth segment.

Furthermore, the company has been active in strategic acquisitions, such as the purchase of key product lines from Semilab International, bolstering its portfolio and expanding its technological capabilities. This combination of organic innovation and targeted acquisition appears to be paying dividends.

Onto Innovation's performance is also mirrored by its larger competitors, confirming the sector-wide boom. Industry giants like KLA Corporation and Applied Materials have also reported record or near-record results, citing the same AI-driven demand. KLA, for instance, recently guided for over 20% growth in its semiconductor equipment business in 2026, while Applied Materials pointed to the acceleration of AI computing as a primary fuel for its strong performance. This competitive context underscores that while the market is large and growing, execution and technological leadership are crucial for capturing share.

As the May 5th earnings date approaches, investors will be looking for confirmation of the stellar preliminary figures. The focus will be on the details behind the numbers: the precise contribution from advanced packaging versus other segments, the impact on gross margins, and any further updates to the full-year outlook. With Q1 revenue already exceeding expectations and Q2 guidance pointing to continued acceleration, Onto Innovation has set a high bar for the rest of the year.
