Onto Innovation (ONTO) has opened 2026 with Q1 revenue of US$291.9 million and basic EPS of US$0.68, setting a clear benchmark for how the rest of the year may shape up. The company has seen quarterly revenue move between US$218.2 million and US$291.9 million over the last six reported periods, while basic EPS has ranged from US$0.21 to US$1.30. This gives investors a concrete sense of how top line and per share earnings have tracked through recent cycles. With trailing 12 month net profit margins sitting below the prior year and a sizeable one off loss still in the rear view mirror, this set of results puts the focus squarely on how sustainably the business can protect and rebuild margins from here.

With the headline numbers on the table, the next step is to see how this earnings print lines up against the widely followed growth and risk narratives around Onto Innovation and where the latest trends in margins either back those stories or push against them.

Margins Reset After 21.3% To 10.3% Drop

• Over the last 12 months, Onto Innovation reported a net profit margin of 10.3% compared with 21.3% a year earlier, alongside a US$84.0 million one off loss that affected profitability.
• Consensus narrative expects margins to build over the next few years, which sits in contrast to the recent margin compression, so it is worth asking how that gap could close:
  • Trailing 12 month net income excluding extra items is US$106.4 million on US$1.0b of revenue, so the recent results already reflect both the lower margin and the one off loss.
  • Analysts are still forecasting revenue growth of 17.9% a year and earnings growth of 47.3% a year, so the current 10.3% margin is being interpreted as a starting point rather than a new normal.

TTM Earnings Of US$2.16 Per Share

• On a trailing 12 month basis, basic EPS sits at US$2.16, backed by US$1.0b of revenue and US$106.4 million of net income excluding extra items.
• Bulls argue that new platforms and acquisitions can support much higher earnings over time, and the recent EPS pattern gives some support but also leaves questions:
  • Quarterly basic EPS over the last six reported periods moved between US$0.21 and US$1.30, which shows earnings can flex quite a bit between stronger and softer periods.
  • Bullish views talk about recurring software and acquired product lines lifting earnings, and the current US$2.16 of trailing EPS is the baseline those expectations build from.

P/E Premium And DCF Gap

• With the share price at US$294.05, the stock is quoted at a 137.5x P/E on trailing earnings and above the DCF fair value of US$216.78.
• Bears point to this valuation as a key risk, and the current numbers give them several specific data points to lean on:
  • The 137.5x P/E is well above the 53.7x average for the US Semiconductor industry and the 86.6x peer average, so investors are paying a much higher multiple than the sector baseline.
  • With net profit margin at 10.3% and the one off US$84.0 million loss still in the trailing period, skeptics suggest that any further margin pressure could make this premium harder to justify.
