Net profit for the 12 months through Sept. 28 was 31.8 million pounds ($49.1 million), down from 42.5 million pounds a year earlier. Britvic said the fall in profit was largely the result of 18.3 million pounds of one-time operating costs, relating mainly to the closure of the company's Cork factory in Ireland.
Revenue over the period rose 29 percent to 926.5 million pounds, defying the economic downturn.
The Tango soda maker said revenue was boosted by strong growth in its sales of juice and Gatorade.
As a result, shares closed up 6 percent to 232 pence in London.
"This is a strong performance achieved despite very challenging trading and cost environments," said Chief Executive Paul Moody.
