German industrial group Thyssenkrupp revised its full-year forecasts on Friday, saying it now expected negative free cash flow as working capital rises due to higher prices for input raw materials and increased sales volumes.

The steel-to-elevators group said free cash flow would likely be in a negative triple-digit million-euro amount, versus its previous forecast for a slightly positive result.

Thyssenkrupp also raised its full-year forecast for adjusted earnings before interest and tax (EBIT) to 1.8 billion euros ($2 billion) from 1.7 billion after beating market expectations for EBIT, sales and orders in the second quarter.
