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.

The K+S Group expects EBITDA for the 2022 financial year to range between EUR 1.6 billion and EUR 1.9 billion (2021: preliminary around EUR 960 million, including approximately EUR 220 million one-off effect from the REKS transaction). This forecast significantly exceeds the current market expectation (Vara 2022 consensus: EUR 1.269 billion). K+S will therefore more than double EBITDA compared to the figure of the previous year (adjusted for the effect from the REKS transaction).

Based on preliminary earnings figures for the K+S Group financial statements as of December 31, 2021, EBITDA of continuing operations amounts to approximately EUR 960 million (previous outlook 2021: EUR 830 million; Vara consensus: EUR 863 million; both including REKS transaction; previous year: EUR 266.9 million).

Today, the German Federal Cartel Office has granted the final approval for the merger of the new REKS joint venture.
