Yoox Net-a-Porter Group, the entity created following the merger of Yoox and Net-a-Porter, has reported a sales growth of nearly 31 percent over the course of 2015. The merger was effective Oct. 5, 2015. Sales were boosted by the increasing use by consumers of mobile phones and tablets for shopping. At constant currencies, pro-forma sales for the online fashion retailer rose by 21 percent to €1.7 billion.

The merger was accompanied by organizational changes. The group has been restructured into three separate business lines: In-season, which includes Net-a-Porter, Mr. Porter, Porter magazine, The Corner, and Shoescribe; Off-season, which includes The Outnet and Yoox; and Online flagship stores, as the group powers 40 online flagship stores including those of luxury brands like Armani and Lanvin. The new structure became effective on Feb. 1.

The In-season business posted sales of €893.3 million during the year, representing a 36.9 percent increase from 2014, mostly driven by Net-a-Porter and Mr. Porter. Off-season sales jumped by 26.1 percent to €596.4 million. The revenues from online flagships rose by 19.2 percent. 

Following the reorganization into three business units, Alison Loehnis, former president of Net-a-Porter, is now president of In-season, and responsible for 53.7 percent of the overall group's revenues for the year ended Dec. 31. Lucas Martines, formerly the president of Yoox.com, is now president of the Off-season business, which made up 35.8 percent of the group's revenues. Paolo Mascia, who was previously in charge of Yoox' monobrand division, is now president of the group's online flagship stores, which accounted for 10.5 percent of the group's sales by the year end. All three presidents report directly to Federico Marchetti, the group's chief executive.
