We are pleased to invite you to Atlas Copco’s Capital Markets Day 2004. This time we will meet in Örebro, Sweden, on September 21, 2004.

The purpose of the meeting is to give an update on the strategy and development of the Atlas Copco Group and also to cover a specific theme. This time we want to focus on the Construction & Mining Technique business area and use this meeting to give you a more in-depth look at our activities in this business.
