Ad hoc: HeidelbergCement’s figures for 1st quarter 2006 well above previous year

The key result figures of HeidelbergCement for the 1st quarter 2006 significantly exceed previous year’s figures.

EURmJan.-March 2006Jan.-March 2005
Operating income before depreciation19085
Operating income64-35

The improved figures can be explained amongst others with favourable market conditions in North America, an optimised cost level following first results of the implementation of the “win” project and positive growth in many markets. We therefore expect a significant increase in turnover and results for the entire year.

The interim report for the 1st quarter 2006 will be released on 4 May 2006.
