This represents a reduction of revenue as compared to the last projection around 312.5 million made on 21 August 2018 by 6.1%. The development is due to the postponement and delay of orders from Russian customers, lower proppant prices in the second half of 2018 and to a sensitive weakened of average exchange rate of EUR/RUB in H2 2018 versus the same indicator in Q1-Q2 2018 by 5.7%.
