Onto Innovation To Acquire Semilab International’s Materials Analysis Business
Onto Innovation has recently announced that it has entered into a definitive agreement to acquire the materials analysis business of Semilab International for $475 million in cash and 706,215 shares of Onto Innovation common stock – valuing the total transaction at approximately $545 million.
The acquisition adds four complementary product lines providing inline wafer contamination monitoring and materials interface characterization. As the use of exotic materials in semiconductor manufacturing rapidly expands, demand for advanced materials analysis is growing significantly. This portfolio has grown at an approximately 20% compound annual growth rate since 2021 and is projected to generate approximately $130 million in annual revenue in 2025. Onto Innovation expects to further enhance the customer value proposition by integrating its Ai Diffract modeling engine and leveraging advanced dimensional metrology, helping speed yield learning for new devices in packaging, power semiconductors and potentially the advanced nodes.
This acquisition aligns with Onto Innovation’s strategy to excel in high-growth, high-margin segments of the semiconductor value chain, particularly where device complexity is accelerating, such as the production of chips required for AI applications. It reflects the company’s disciplined approach to capital allocation and commitment to long-term shareholder value. The transaction is expected to be immediately accretive to both gross and operating margins and to increase non-GAAP earnings per share by more than 10% in the first year following close, adding over $130 million to Onto Innovation’s annual revenue. Onto Innovation expects a smooth integration, supported by strong cultural and technical alignment between the two organizations.
“We’re excited to welcome Semilab’s talented materials characterization team to Onto Innovation,” said Mike Plisinski, chief executive officer of Onto Innovation. “This acquisition expands our portfolio of process control technologies, which work together to help customers achieve their yield targets. This portfolio is exciting as it has demonstrated broad customer appeal and we see additional technical synergies with our modeling and acoustic metrology technologies, which we expect to provide additional benefit to our customers.”
