Carlsberg said third-quarter sales stagnated as poor summer weather held back volumes in Europe and its sales in Russia fell compared to the previous year. Organic net revenue growth was flat in the three months to the end of 30 September. Beer volumes fell 3% on an organic basis for the period. In Northern & Western Europe, the group's market share improved slightly, mainly driven by Poland and the UK. In the first nine months of 2011, the group’s beer volumes grew by 2%, net revenue growth was 4% while operating profit declined by 12% in line with expectations. Joergen Buhl Rasmussen, chief executive, said: “We have faced headwinds from rising input costs, adverse weather conditions and soft trading conditions in our largest market. With an uncertain outlook for the global macro economy and consumer sentiment, we will closely monitor changes in our markets, so that we can adjust our investments in sales and marketing activities accordingly.”
