Britvic Plc said poor weather and a recall of its Fruit Shoot products saw quarterly revenue drop by 11% in Ireland and 5% in the UK.
The company also said it was reviewing its plans for 2013 and expected to lower its previous outlook, including the deferral of a new Fruit Shoot line in France until 2014 at the earliest.
Britvic said prices are falling in Ireland because of aggressive competition and discounting particularly in supermarkets.
Shares in the company, whose own brands include Tango and J2O, have shed over 14% since the start of the year. They closed at 285.1 pence in London yesterday.
"The weak consumer environment and very disappointing weather at a key time for soft drink sales have had a marked impact on our performance," Chief Executive Paul Moody said. "In the foreseeable future, our resources will be fully focused on re-establishing Fruit Shoot in the market as soon as possible."
Last week, Britvic said the impact of the recall of its popular children's drinks Robinsons Fruit Shoot and Fruit Shoot Hydro in the UK and France was worse than it had anticipated.
