In Q1 2026, Onto Innovation reported revenues of $291.9 million, underpinned by the late-2025 acquisition of Semilab USA which enhanced its inline contamination and materials characterization offerings. The company’s pending minority investment in Rigaku introduces strategic potential but carries regulatory approval risks. Onto Innovation’s comprehensive toolset across front-end and back-end semiconductor manufacturing, combined with advanced software integration, reinforces its competitive moat amid growing demand for advanced packaging driven by AI applications. Near-term execution hinges on successful integration, realization of acquisition synergies, and closing of the Rigaku deal.
