Consolidated group revenues rose 23 percent at constant exchange rates to 726.4 million, with the Moncler brand at 604.8 million (+28 percent) and Stone Island at 121.6 million (+5 percent), a note said.

According to the consensus provided by the company, analysts expected revenues of 689 million, including 565 million for Moncler alone and 124 million for Stone Island.

Robert Triefus, meanwhile, has been appointed CEO of Stone Island (more specifically Sportswear Company, which develops, manufactures and distributes the Stone Island brand) effective June 1. "As the first phase of Stone Island's development, in which the brand took direct control of the main markets in which it operates, draws to a close, Triefus will lead the second phase of development, dedicated to the strategic evolution of the brand and international growth," says a second note.

Triefus comes from 15 years at Gucci (Kering group) and had previously worked for Armani and Calvin Klein.

Moncler Group's quarterly revenues were supported by strong growth in Asia (+32 percent)-thanks to a recovery in China, but also in Japan and Korea-and in Europe (+29 percent), driven by local demand and tourists.

"The year has just begun, the geopolitical environment remains uncertain, and the most important months are still ahead of us, but we are ready to face them and seize exciting new opportunities," president and CEO Remo Ruffini says in the note.
