Kering, the owner of Gucci, on Tuesday reported lower second-quarter financial returns than what was expected, pointing to "uncertain" global factors.

Gucci sales plunged as shoppers turned away from Kering’s largest brand that’s undergoing a second design revamp in three years.

Gucci sales, which make up nearly half of total group revenues, plunged 25% over the quarter to 1.46 billion euros.
