K+S AG is raising its forecast for the expected EBITDA of the K+S Group for the current year to € 2.3 billion to € 2.6 billion (previously: € 1.6 billion to € 1.9 billion; previous year: € 969 million). The increase in the forecast is mainly based on further higher average prices in the Agriculture customer segment.

This forecast significantly exceeds the current market expectation (Vara 2022 consensus: EUR 1.269 billion).
