C&C Group, the company behind Magners cider, has warned that poor weather could hit its full year operating profit.

“Very poor weather in June and into July together with continued heavy price-led competition is likely to lead to a weak second quarter and, as a result, while the group expects strong volume growth for the full-year in Great Britain, it is reducing its sales volume expectation,” the group said in a trading update.

Lower sales volume expectations were likely to result in full-year operating profit matching last year, it added.

And marketing investment and costs associated with capacity expansion would result in a decline in operating profit for the half-year to August 2007.

Revenue rose 15% in the quarter to 31 May, boosted by the performance of Magners and Bulmers. Soft drinks revenue rose 7% but spirits and liqueurs fell 6%.
