ALTANA seeks delisting in the U.S.

Frankfurt / Wesel, April 26, 2007. ALTANA’s Management Board has decided to delist from the New York Stock Exchange (NYSE) and to file a deregistration application with the Securities and Exchange Commission (SEC). After successful deregistration, ALTANA will no longer be subject to the regulations of the U.S. securities laws including the reporting obligations and regulations of the Sarbanes-Oxley Act resulting from a registration with the SEC. ALTANA has not arranged for the listing of its ADSs or ordinary shares on another national securities exchange or for the quotation of its common stock in a quotation medium in the United States.

The U.S. activities of ALTANA Pharma, which was sold to Nycomed as of December 31, 2006, had caused ALTANA to opt for a listing on the New York Stock Exchange in 2002. After the sale of ALTANA Pharma, this reason is no longer valid. By delisting from the NYSE, ALTANA is taking into consideration the new Group structure as a pure specialty chemicals company.
