It said revenue in the three months to September 29 rose by 12.8% to £366.4 million helped by the warm summer weather and full availability of the Fruit Shoot brand.
Britvic indicated Fruit Shoot's market share in Britain is now back to where it was before a safety problem with a new bottle design forced a major recall in July last year. Still drink sales in Britain were 23.2% ahead, with prices up 6.2% and volumes by 16.2%, while carbonated beverages were up 8.6% overall, with prices rising 2.6% and volume 6.7%.
Irish quarterly revenue grew by 1.8%, in France it rose 13.5% and other international sales were up 35.7% with Fruit Shoot now rolled-out to 35 states in the US.
The fourth quarter performance means revenue for the full financial year is expected to come in 4.4% ahead at £1.32 billion, with operating profits predicted to be slightly greater than market expectations.
Analyst Wayne Brown, at Canaccord Genuity, upgraded Britvic shares from sell to hold and said: "We await the prelim results to see the true extent to which Britvic will be able to pay down debt and reduce its pension obligations against a backdrop of yet again more and more exceptional charges."
