At the end of August SuperGroup implemented an upgrade programme to its warehouse management systems to increase capacity and efficiency at its Barnwood site to meet future growth in demand. Once live, the business encountered some short-term issues in the transition which has caused a significant, temporary reduction both in the amount of stock and range of sizes reaching its UK stores.

Superdry estimate that the total cost of this isolated event, including the additional temporary warehousing capability and resulting lost sales during the period, will impact the current year's profitability by between £6-9 million. Stock levels will also increase by c.£2 million.
