Irn-Bru maker AG Barr said increased marketing and promotions had helped drum up demand for its drinks in its first quarter, sending revenues up 5.2%.
The firm's brands include Rubicon, Orangina and Irn-Bru, the fizzy orange drink that outsells Coca-Cola in Scotland.
It also said its chairman, Ronnie Hanna, had decided to retire from the board at the end of the year.
Hanna has been on AG Barr's board for 11 years, serving five as chairman.
AG Barr said today that total revenue for the 15 weeks to May 11 had risen 5.2% on a year ago, well ahead of market growth of 1.9%, and had been underpinned by rising volumes.
The company said margins were in line with its expectations and it remained confident on its full-year targets.
