Revenue grew at constant exchange rate at 3.8%.
• EBITDA € 276.8 million, increased by 8.4% at current exchange rate compared to 2018 and equal to 39.2% of revenues. Increase in profitability mainly driven by the upward trend in the Gross Profit, following an increase of specialty sales and a favorable geographical and channel mix. Net of both the exchange rate effect and some one-off costs in Q4'19, among which those relating to the manufacturing facility closure in South Africa, EBITDA increased by 7.6%, equal to 39.6% of Group Revenues.
