Eon on Wednesday raised its full-year earnings outlook for the second time this year as Germany’s largest power company benefited from a lower-than-expected increase in interest expenses on its acquisition-enlarged debt pile.

The Düsseldorf-based company said full-year adjusted net income, which excludes extraordinary effects such as the marking-to-market of derivatives, would decline by 3-5 per cent, an improvement on its previous forecast of a 5-10 per cent fall.
