Expro International is to sell its connectors and measurements (C&M) business to Siemens for a total consideration of $630m.

The sale, subject to approval of competition authorities in Norway, is expected to take place in May and also includes Expro brands Tronic and Matre.

The business provides services in design, manufacture, assembly and installation of subsea electrical power and data connectors, as well as temperature and pressure sensors. Last year, it had revenues of $119m.

Expro chief executive officer Charles Woodburn said that in the past 12 months, the company received several unsolicited indications of interest for its C&M business.

"We will look to use the net proceeds from the sale of the C&M business to repay existing borrowings and support our strong position within the industry by further investing in the growth strategy of our core business," he said.

Arle Capital Partners partner Mark Dickinson added that his company would now concentrate on working with Expro to ensure it capitalises on its existing growth.

"Expro has had a winning start to 2012, having recently added several significant order wins and enjoying an order pipeline of well over $1 billion," he said.
