WILMINGTON, Mass. -- (Business Wire)

Onto Innovation Inc. (NYSE: ONTO) today announced the successful closing of its previously announced acquisition of key product lines from the materials analysis business of Semilab International. Valued at approximately $495 million, the transaction adds three advanced product lines—FAaST^®, CnCV^® and MBIR—to Onto Innovation’s portfolio, significantly enhancing the company’s capabilities in inline wafer contamination monitoring, materials characterization and unique surface charge metrology.

“We’re thrilled to welcome the talented team of engineering, support, and applications, and all other functions that have made these products so successful to Onto Innovation. Semilab customers can expect uninterrupted service, further enhanced by Onto Innovation’s global support and manufacturing infrastructure,” said Mike Plisinski, chief executive officer of Onto Innovation. “This acquisition strengthens our materials portfolio in high-growth segments like advanced logic, AI-enabling advanced packaging, and power semiconductors. The combination of Semilab’s products alongside Onto’s OCD or defect inspection capabilities will enable more accurate electrical defectivity location and characterization, not previously available in the industry, greatly reducing the number of latent defective devices sold into the market and ultimately generating higher value for our customers.”

For the fourth quarter, the Company is updating its revenue guidance range to $258 to $275 million as the acquisition is expected to contribute approximately $8 to $10 million of revenue from today through January 3, 2026. Although the acquired business is performing at a level consistent with the expected run rate, the majority of fourth quarter revenue was recognized prior to today’s close due to previously committed customer shipment dates. Excluding the impact of purchase accounting, the acquisition is expected to be immediately accretive to margins and add approximately $0.02 to $0.04 to diluted earnings per share in the fourth quarter. The Company continues to expect the acquired product lines to contribute approximately $120 million in revenue in 2026, with revenue likely weighted towards the second half of the year. The Company will provide additional commentary on its next earnings call in early 2026.

Barclays Capital Inc. served as financial advisor, and Simpson Thacher & Bartlett LLP as legal advisor, to Onto Innovation in connection with the transaction. Semilab was advised by Needham & Company, LLC and Hill, Ward & Henderson P.A.
