Schering AG (FSE: SCH, NYSE: SHR) announced today that a dividend of
EUR 1.20 per share will be proposed to the Annual General Meeting on
April 19, 2006 based on a continuous positive business development in
2005. This equals an increase of 20 percent compared to the previous
year.

Furthermore, Schering announced a settlement with Bayer AG regarding
parts of the warranty claims asserted by Bayer. This settlement
relates to the sale of Schering's stake in the plant protection
company Aventis CropScience in 2002. This will lead to a reversal of
provisions with a positive one-time effect on the result after taxes
of approximately seventy to a hundred million Euro.

This positive effect will partially compensate for potential negative
one-time effects. These result from restructuring measures in regard
to Schering's FOCUS-program, which, among other things, includes a
strategic realignment of its radiopharmaceutical business CIS bio
International.
