Onto Innovation stock gains as Q1 2026 figures and advanced packaging outlook impress

Onto Innovation stock (ISIN US6833441057) closed at USD 250.11 on Nasdaq on September 17, 2026, giving the semiconductor equipment specialist a market capitalization of about USD 15.29 billion as investors react to strong Q1 2026 figures and robust guidance for advanced packaging tools.

Q1 2026 results and guidance underpin momentum

According to MoneyDJ, Onto Innovation reported revenue of USD 292.0 million in the first quarter of 2026, with the period showing non-GAAP gross margin of 55.7 percent and non-GAAP operating margin of 26.7 percent.

Non-GAAP earnings per share reached USD 1.42 in Q1 2026, supported by strong demand in both advanced packaging and special device segments, signaling a solid start to the year compared with the company’s historical performance in earlier periods described by MoneyDJ.

For Q2 2026, Onto Innovation guided revenue to a range of USD 320 million to USD 330 million, implying growth of roughly 9.6 percent to 13.0 percent versus the reported Q1 2026 revenue of USD 292.0 million, with non-GAAP gross margin expected between 56.0 percent and 56.5 percent and non-GAAP operating margin between 28.0 percent and 28.6 percent as shown in the same MoneyDJ report.

Advanced packaging and Semilab acquisition drive growth story

The Q1 2026 revenue mix highlights the central role of advanced packaging in Onto Innovation’s strategy, with special devices and advanced packaging contributing USD 160.0 million in the quarter, about 54.8 percent of total revenue of USD 292.0 million, and approximately two-thirds of that USD 160.0 million coming from advanced packaging tools according to MoneyDJ.

In the same Q1 2026 breakdown, Onto Innovation’s advanced node business contributed USD 80.0 million in revenue, with around 60 percent coming from memory customers and 40 percent from logic, underscoring the company’s exposure to both cutting-edge DRAM and NAND and leading logic foundry processes as detailed by MoneyDJ.

Onto Innovation expects full-year 2026 revenue to exceed USD 1.3 billion, with management forecasting that second-half 2026 revenue will grow at least 15 percent compared with the first half, and aiming for advanced packaging revenue to expand by more than 50 percent while advanced node revenue grows about 25 percent over the year, according to guidance summarized by MoneyDJ.

The same source notes that Onto Innovation has begun receiving initial orders for silicon photonics equipment, and its JetStep system has been qualified by two AI device packaging suppliers, which ties the company more directly to the acceleration in artificial intelligence hardware deployment documented by MoneyDJ.

To further strengthen its position in advanced materials and metrology, Onto Innovation announced a USD 710 million all-cash investment to acquire a 27 percent equity stake in Rigaku, with the transaction expected to close in the second half of 2026 and funded mainly from existing cash, as reported by MoneyDJ.

Analyst attention and valuation context

A recent overview from Simply Wall St on September 18, 2026 notes that Onto Innovation has attracted strong support from brokerage firms, with average recommendations positioned near the top of their rating scales based on around 13 covering firms.

As Simply Wall St highlights, the renewed analyst interest is tied to expectations that Onto Innovation’s earnings could benefit significantly as chipmakers rely more on process control tools for complex packaging and new device architectures, in particular as advanced packaging orders and silicon photonics applications move from initial qualification to volume deployment.

An article referenced by TechFlowPost discussing Onto Innovation’s Dragonfly G5 platform suggests that volume ramp-up of this advanced packaging inspection system could support around 30 percent growth over the next few years and create room for valuation repricing, framing the stock as a potential beneficiary of AI chip and heterogeneous integration investment cycles.

At the September 17, 2026 close of USD 250.11, Onto Innovation’s shares sit well below their recent quoted intraday level of USD 258.09 cited in the same week by MoneyDJ, but the combination of growing revenue, high margins and analyst upgrades keeps the focus on how far earnings can expand as the company executes its advanced packaging strategy.
