Atlas Copco closes acquisition of Dynapac

Stockholm, Sweden, May 31, 2007: Atlas Copco AB today completed the purchase of
Dynapac AB, a leading supplier of compaction and paving equipment for the road
construction market.

The agreement with Altor Equity Partners to acquire Dynapac was first announced
on Feb. 5 and has now received approval from all relevant authorities.

Dynapac, which had sales in 2006 of approximately BSEK 4.6 (MEUR 505) and 2 100
employees, will operate as a separate division, Atlas Copco Road Construction
Equipment, within the Construction and Mining Technique business area. 

Claes Ahrengart has been appointed President of the newly formed division and
will begin in his new position immediately. He has previously been President of
Atlas Copco's Construction Tools division. Dynapac's former CEO, Ronald Kok,
will be a board member of the Road Construction Equipment division.

The acquisition of Dynapac, which has production sites in six countries and
sales in over 115 countries, will give Atlas Copco additional products and sales
channels to grow in the expanding road construction market, particularly in
nations such as China and India.
