The Waltham, Mass.-based lab instruments giant plans to pay about $118.50 per share for Dionex, for a total value of more than $2.1 billion.
“The acquisition of Dionex is consistent with our strategy of accelerating growth by increasing our depth of capabilities in innovative technologies and emerging markets,” said Marc Casper, president and chief executive officer of Thermo Fisher said in a prepared release. “This combination creates a leading offering for our customers in chromatography instruments, software, consumables and services. With Dionex, we will expand our presence in attractive applied markets, including environmental analysis, water testing and food safety, and increase our commercial capabilities in China and other growing Asia-Pacific regions.”
