(Reuters) – A.G. Barr on Tuesday warned of a hit to its operating margins in the short term due to inflationary pressures and acquisitions, even as the Irn-Bru maker forecast annual profit growth in line with its expectations.

The warnings comes after the beverage maker reported a 13.3% rise in adjusted profit before tax for the year ended Jan. 29 to 43.5 million pounds ($53.58 million).
