The Cumbernauld-based firm unveiled the contract alongside interim results yesterday showing an 11 per cent increase in underlying profits, which hit £18.4 million in the six months to 27 July.
Sales increased by 5.4 per cent to £135.7m, helped by the firm’s sponsorship of the Glasgow Commonwealth Games.
The group will start to sell, market and distribute Snapple in January, after Dr Pepper’s current agreement with Orangina expires.
AG Barr chief executive Roger White said: “We are very excited about our new partnership. Snapple is an authentic, high quality brand that is very successful in the United States and we strongly believe in the significant potential of Snapple in Europe.”
He said the group would decide how much to invest in marketing the brand once it takes charge in the new year.
