Sales at fashion retailer SuperGroup, owner of the ultra-trendy Superdry brand, continued to climb steeply in the third quarter and continued growth is expected.

SuperGroup, which floated last year, posted a 91.8% increase in retail sales to £61.4m in the period to January 30, bringing the figure for the nine months to that date to ££115.8m – an 81.7% increase.

Total group sales rose 86.9% to £81.7m in the quarter and over the nine-month period leaped 74.7% to £172m.

The retailer opened six shops during the quarter, bringing the UK total to 59.

SuperGroup is expanding fast internationally, partly through franchising, and last week bought its France and Benelux franchise and distribution partner CNC.

SuperGroup chief executive Julian Dunkerton said: “Such strong results combined with our continued UK roll-out, further expansion across Europe and additional store openings in the Far East, US, Australia and the UAE demonstrate the continued global potential of our brand.

“Our acquisition of CNC provides an exciting opportunity to further accelerate our European expansion over the coming years.”

Numis analyst Andy Wade said that SuperGroup has made “dramatic progress” since the launch of Superdry in 2003. He said: “We believe the success of the brand is far more than a fad, with success built on a high quality product priced to fill a gap in the market.”
