Trendy clothing producer Quiksilver Inc on Wednesday posted a double-digit jump in third quarter net profit as it was boosted by a sharp rise in revenue on the back of a big increase in sales through holiday bookings.

The California-based firm, whose brands include Roxy, Raisins and Radio Fiji, reported net earnings for the quarter ended July 31 of $11.9 million, or 21 cents per share, compared to a profit of $8.8m, or 18 cents per share, in the year-ago period.

Revenue jumped 44 per cent to $251.5m from $175m last year with bookings for the holiday season, excluding its newly added Asia/Pacific division, up 11 per cent overall on a constant-dollar basis.

Quiksilver said revenues in the Americas increased 28 per cent during the quarter to $137.4m from $107.3m, with European revenues up 41 per cent to $93.9m from $66.6m.

Chairman and CEO, Robert McKnight Jr, said: "We were pleased with our results for the quarter which were primarily driven by a strong increase in sales and significant gross margin expansion.

"Our financial performance reflects the vitality of our brands and an ongoing commitment to develop the best product in the marketplace.

"Our ability to continue to post strong results despite the ongoing challenges in the retail environment is a testament to our diversified portfolio of leading lifestyle brands, disciplined execution of our key strategies and ongoing dedication to becoming the dominant lifestyle company for the global youth market.

"Our multi-brand, multi-channel, multi-country approach to our business sets us apart from our competition and offers us significant growth opportunities into the future."
