Luxury retailer Barneys New York Inc has posted a 104 per cent jump in first quarter pre-tax earnings to $10.5 million, up from $5.1m in the same period a year earlier.

The company, which operates flagship stores in New York City, Beverly Hills and Chicago, also reported a 23.5 per cent increase in net sales for the quarter to $112.8m, up from $91.4m in the previous first quarter.

In addition, comparable store sales went up 22 per cent during the three-month period, while net income rose to $3.5m from a year-ago loss of $1.2m.

CEO Howard Socol said the first quarter results represented a "very positive start" to the current fiscal year.

"Sales were strong in substantially all merchandise categories and across all of our store formats," he said.

"These results are a testament to the continued execution of our core business strategies and the current momentum in the high-end retail sector."

In addition to its flagship locations, Barneys operates three regional full-price stores, three Co-Op Barneys New York stores, 12 outlet stores and two semi-annual warehouse sales events.
