Mahmud Kamani and Carol Kane, joint CEOs, said: “Our multi-brand strategy is delivering above-market rates of growth globally. Significant market share gains have been achieved in all of our key focus markets, with our compelling combination of the latest fashion at incredible prices, backed by great customer service resonating strongly with our customers. The scale of group revenue is aligning with our ambition to become one of the dominant global online retailers and our focus on profitability continues to deliver industry-leading margins.
“Our infrastructure continues to see record levels of investment as we invest ahead of our growth curve and develop a distribution network capable of supporting £3bn of net sales globally. The distribution centre extension and automation project at Burnley remain on track to complete towards the end of the financial year, with PrettyLittleThing’s move to its own warehouse expected to complete early in the second half of the financial year.
“We remain highly encouraged by our performance in the first quarter and confident of our expectations for the remainder of the year and beyond as we continue to execute on our winning strategy.”
