Q2 2026 Results

• Gross margin: 53.4% GAAP (vs. 48.2% in Q2 2025); non-GAAP gross margin of 57.0% vs. 54.5% a year earlier.
• GAAP operating income: $63.6 million, or 18.5% of revenue, nearly doubling from $32.2 million (12.7% of revenue) in Q2 2025.

What Drove the Results

Adjusted EPS of $1.93 beat the $1.72 consensus by $0.21, a 12.2% positive surprise. Revenue of $343.1 million reflected broad-based demand strength: Advanced Nodes revenue grew 50% sequentially to a new quarterly record, driven by logic and memory customers, while Specialty Devices and Advanced Packaging revenue also reached an all-time high, supported by 2.5D logic, high-bandwidth memory, and silicon photonics demand. GAAP operating income of $63.6 million grew 97.5% year-over-year on the 35.3% revenue increase, reflecting substantial operating leverage.

The GAAP-to-adjusted EPS gap ($1.21 vs. $1.93) reflects non-cash and acquisition-related adjustments including amortization of intangibles and merger-related expenses that Onto excludes from its non-GAAP figures. For the first six months of 2026, non-GAAP net income of $166.8 million rose sharply from $136.1 million in the same period of 2025, even as GAAP net income of $93.9 million dipped from $98.0 million, illustrating how amortization charges weigh on reported results.

Backlog surpassed $1 billion for the first time in company history, a structural demand signal that management cited as support for its expectation of a strong second half of 2026 and demand trends extending into 2027.

Guidance

For Q3 2026, Onto Innovation guided revenue of $380 million to $400 million, GAAP diluted EPS of $1.54 to $1.70, and non-GAAP diluted EPS of $2.18 to $2.38. The company expects GAAP gross margin of 57.3% to 57.8% and non-GAAP operating margin of 31.5% to 32.5% in the third quarter, both above Q2 2026 levels.

Wall Street View

Analyst sentiment on Onto Innovation is broadly constructive heading into the second half of 2026. The company's record backlog and management commentary pointing to sustained AI and high-performance compute demand provide the forward-looking context analysts have been monitoring alongside the quarterly financial results.

Investor Takeaway

Onto Innovation's Q2 results confirm that operating leverage is materializing at scale: a 35.3% revenue increase translated into a 97.5% year-over-year gain in GAAP operating income, a ratio that suggests meaningful margin expansion potential if revenue growth holds. The record $1 billion-plus backlog provides visibility into H2 2026 and beyond, but investors should note that the gap between GAAP EPS of $1.21 and adjusted EPS of $1.93 reflects ongoing amortization and acquisition costs that weigh on reported profitability, making the trajectory of non-GAAP margins the more relevant execution benchmark to watch.
