C&C Group, the Irish cider maker, said it expects operating profit for the six months to 31 August to be down 35% on the previous year due to this summer’s extremely poor weather. The company, which owns the Magners brand, said that trading performance had deteriorated at an unexpected rate during the second half of July and that its cider sales volumes for the month declined significantly on the same period in 2006. The group said that taking into account the low rate of sale in July and the anticipated knock-on effect into August, it had reduced its view of the half-year outcome. It said that the size of the decline reflected weak cider volumes combined with substantially higher manufacturing and marketing costs. The company indicated that it expected operating profit for the full year to 28 February 2008 to match the previous year, including the anticipated decline in operating profit for the first half of the year.
