The Competition Commission will deliver its provisional findings on the proposed merger between Britvic and AG Barr at the end of May or early June.

The findings will be made public before the publication of the final report, which is due by the end of July.

Speaking to The Grocer after Irn-Bru manufacturer AG Barr reported a 4.3% increase in full-year pre-tax profits to £35m, AG Barr CEO Roger White said that having to provide the commission with the data and information required for the investigation was “reasonably onerous” but the company remained committed to the proposed merger.

“We’ve believed since the start of the process and still believe today that the proposed merger will not result in any substantial lessening of competition,” he said.

Commenting on the results, White added: “It is a strong set of results in a busy and challenging year, achieved despite the poor weather we endured over the summer and, in the second half, the added effort and uncertainty with the potential merger.”

The accounts revealed AG Barr had spent £3.2m on professional and legal fees related to the merger.
