The maker of Irn Bru and Rubicon AG Barr warned on Tuesday that the full year revenue could be down by up to 15%.
This comes amid trading volatility due to the pandemic, and revenue in the year to the end of January 2021 is predicted to fall by as much as 15%, compared to the previous year.
In the 26 weeks to 25 July, revenue was down by 8% to £113m on the previous year, whilst in the three months from April to June revenue was down by 12% during the lockdown.
Chief executive Roger White said: “I am incredibly proud of how our teams across the business have responded to the Covid-19 pandemic.
“These have been difficult times for everyone however, despite the challenging environment, we have maintained our quality and service standards, thanks to the dedication and adaptability of our people.
“We are a profitable and cash generative business in a robust drinks sector and I am confident that our business will continue to prove its resilience for the balance of the year and beyond.”
