Onto Innovation's stock experienced a notable surge, climbing 6% on Tuesday and marking an impressive 85% year-to-date increase. This robust performance is primarily fueled by the escalating demand for its High Bandwidth Memory (HBM) and advanced packaging inspection tools, driven by the booming artificial intelligence sector. The company's positive trajectory is further supported by a record-setting quarter from its industry peer, Camtek, and NVIDIA's strategic $500 billion partnership aimed at financing AI infrastructure, collectively underscoring a period of significant growth within the semiconductor industry.
On Tuesday, Onto Innovation's shares rose by 5.9% to $308.51, building on Monday's closing price of $291.35. This upward movement is largely attributed to the positive ripple effect from Camtek's exceptional second-quarter 2026 earnings report, released on August 10, 2026. Camtek, a key player in semiconductor process control, reported record revenues of $133.24 million, surpassing analyst expectations of $130.19 million, and delivered non-GAAP earnings per share of $0.78, slightly above the $0.76 estimate. Camtek CEO Rafi Amit highlighted that year-to-date bookings had exceeded $600 million, with deliveries extending into 2027. Furthermore, Camtek projected Q3 revenue between $158 million and $160 million, indicating a 20% sequential growth, and noted a remarkable 70% growth in Advanced Packaging revenue between Q1 and Q4 2026. This growth is predominantly driven by AI-linked HBM memory and chiplet architectures, precisely the areas where Onto Innovation's Dragonfly and Atlas platforms excel.
Onto Innovation's strong position was evident even before Camtek's recent announcement. In its Q1 FY2026 8-K filing on May 5, 2026, Onto reported record revenues of $291.95 million, a 9.5% increase year-over-year, and non-GAAP earnings per share of $1.42, aligning with estimates. The advanced nodes segment saw a 13% sequential increase in revenue. CEO Mike Plisinski emphasized the successful qualification of the Dragonfly G5 inspection system with both a 2.5D logic customer and an HBM customer, as well as a second logic win for the Atlas G6 metrology system in gate-all-around technology. These advancements are crucial for the development of AI capacity, directly benefiting Onto's core business in metrology and inspection tools.
Adding further momentum to the AI supply chain, NVIDIA's announcement of a partnership with financial giants like Apollo and BlackRock to establish a financing platform for AI infrastructure significantly boosted market sentiment. This initiative aims to mobilize over $500 billion in third-party capital, reinforcing NVIDIA's leadership and transforming computing into an attractive investment asset class. Such an influx of capital is expected to spur further data center expansions, directly benefiting companies like Onto Innovation, whose metrology and inspection tools are essential for qualifying HBM stacks and 2.5D logic packages.
Onto Innovation's recent stock performance is part of an ongoing upward trend, with shares appreciating approximately 85% year-to-date and 183% over the past year, bringing its market capitalization to nearly $15.14 billion. Camtek also saw a significant increase, up roughly 49% year-to-date and a 13.1% jump in the past week. Other companies in the semiconductor and advanced packaging sectors, such as Cohu, which gained 4.8%, are also experiencing rallies, indicating broad-based positive sentiment across the industry.
The next critical event for Onto Innovation investors will be the Q2 FY2026 earnings report. Investors will be keenly watching for confirmation of the projected revenue guidance of $320 million to $330 million and any additional insights into advanced packaging order flows that might mirror Camtek's impressive $600 million year-to-date bookings. The market will also monitor whether the stock maintains its current gains and reclaims its recent highs, providing further indications of sustained growth.
