German energy group RWE AG (<a href="https://www.boerse-frankfurt.de/equity/rwe-ag-st" target="_blank">ETR:RWE</a>) said on Thursday that its adjusted net profit plunged to EUR 498 million (USD 558.5m) in the first quarter of 2025 from EUR 801 million a year earlier due to weaker trading business and normalisation of the income in the flexible generation unit.
