Science in Sport shares tumbled 24.3% to 34.4p in late afternoon trading on Friday after the company announced a revenue climb of 12% in HY1 2022, coming in beneath market expectations.
The group reported an estimated improvement in HY2 through brand investment, digital channels and improved pricing.
Science in Sport added that its current assessment of external factors indicated an adverse £3.2 million of costs or margin loss for the year against its budget, including raw material price increases, fuel and logistics costs, people retention expenses and the closure of its Russian business.
The firm said its new Blackburn site was close to completion, with the logistics operation delivering the scheduled efficiencies and cost savings in line with the new business case.
Science in Sport confirmed its gel machine was being installed, with the site set to become fully operational by the end of July 2022.
