VAT Group AG Announces Acquisition of Atonarp

VAT Group AG has agreed to acquire Atonarp Inc., a Japanese company specializing in real-time molecular profiling for semiconductor and industrial processes. This acquisition, valued at approximately CHF 110 million, will be financed through a new bilateral loan agreement. The addition of Atonarp's miniaturized sensor technology complements VAT's core valve business and aligns with its growth strategy outlined in 2025.

The transaction highlights the critical need for precise, real-time monitoring in semiconductor manufacturing, especially as technologies advance below 2nm node sizes. Atonarp’s sensors, which utilize mass spectrometry, provide comprehensive data to enhance process control and integrate AI-driven intelligence into manufacturing.

Both VAT and Atonarp will operate independently post-acquisition. Closing is anticipated in Q3 2026, pending regulatory approvals and customary conditions.
