Molex, a maker of electronic connectors and cable assembly products, said privately owned energy and chemicals conglomerate Koch Industries will buy it for about $7.2 billion.
The deal for $38.50 per share in cash represents a 42 percent premium on average to the Friday closing prices of Molex's two classes of publicly traded shares, Molex said.
Molex will become a standalone unit of Koch Industries and will continue to be run by the company's current management.
