Completion of Acquisition by GE Energy and cancellation of listing.

Sondex announces that the Scheme of Arrangement implementing the £289 million recommended cash offer by Drilling and Wireline Solutions Limited for Sondex is now effective, and Sondex has been re-registered as a private limited company. The acquisition of Sondex by GE Energy will further expand its capability and expertise in oil & gas drilling and wireline technology.

For more than 30 years, GE Energy has served the oil and gas services sector with specialized equipment from its Reuter Stokes Measurement Solutions product lines, which designs and produces detectors for use in high temperature and shock environments.  In oil & gas exploration and production, GE provides equipment to enable oilfield service companies to navigate drill strings and to identify underground oil and gas reserves.  The Sondex acquisition will expand the product portfolio and allow customers worldwide to benefit from the combined capabilities, capacity and resources of the two businesses.

As of 8.00am today, Sondex’s ordinary shares ceased to be listed and trading on the London Stock Exchange.

Martin Perry, Chief Executive of Sondex said:

“Sondex has enjoyed four successful years on the London Stock Exchange; completing five acquisitions and increasing our share price by 460% since we listed.  Our acquisition by GE delivers a good premium, on unaffected share price, to all shareholders and positions the company well for further phases of expansion in the oilfield technology sector.  The whole team look forward to working with GE going forwards.”

Brian Palmer, vice president of GE Energy’s Optimization and Control business commented:

“The Sondex people, technology and global relationships are an important addition to GE Energy's portfolio of businesses, complementing our existing oilfield technology product line.  The company brings to us a broad range of advanced products, as well as a management team and employees with a deep understanding of the customers they serve. We expect the combination to form a technology growth platform for GE going forward."
