The Greek writedown wiped two thirds off Remy’s group net profit, which slumped to €14.1m (£11.83m) in the six months through September.
Remy said there had been a “highly unfavourable impact” on operating profitability in liqueur and spirits from a decline in Metaxa sales in Greece, though it gave no numbers.
However Remy chief Jean-Marie Laborde said he was confident on the second half of the group’s current year through March, partly due to a fresh round of price increases.
“We’re completely confident on the second half,” Laborde said, adding the group’s loss-making champagne unit – which is anyway being sold – would be at the very least break-even at the operating level for the year.
Remy Cointreau is selling its champagne operations, which include the Charles Heidsieck and Piper-Heidsieck brands, to focus more on cognac, which is a popular drink in China.
The group should receive indicative offers for the champagne unit by the end of December and finalise a deal in March, Laborde said.
