Atlas Copco Buys Compressor Rental Business

La Porte, Texas-based Atlas Copco Prime Energy LLC has purchased Scotland-based Aggreko Plc’s
compressor rental business. The deal, worth $18 million, expands Atlas Copco’s Specialty Rental
Division, adding some 200 oil-free air compressors and dryers to its European rental fleet. Various
Atlas Copco companies in Europe purchased the fleet assets.

“Aggreko’s business is a perfect fit with our Specialty Rental Division – as they serve
similar market segments and applications, broadening our customer base in Europe,” said Ronnie
Leten, business area president, Atlas Copco Compressor Technique. “The acquisition of the European
business of Aggreko Plc supports the growth of Specialty Rental’s core business, renting oil-free
air equipment.”
