Sales are expected to increase significantly from the 6.8 billion euros (£5.83 billion) in 2018, along with a slight increase in earnings before interest, tax, depreciation and amortisation (EBITDA), which stood at 227 million last year.

According to a Reuters poll of banks and brokerages, sales in 2019 are seen down 4 percent, while EBITDA is expected to decline by a quarter.
