New York, New York – June 2, 2015 — G-III Apparel Group, Ltd. (NasdaqGS: GIII) today announced operating results for the first quarter of fiscal 2016. G-III’s two-for-one stock split was effective May 1, 2015 and all share and per share data have been retroactively adjusted to reflect the stock split.

For the quarter ended April 30, 2015, G-III reported that net sales grew 18% to $433.0 million compared to $366.2 million in the year-ago period. The Company’s net income for the first quarter was $6.8 million, or $0.15 per diluted share, as compared to $1.3 million, or $0.03 per diluted share, in the prior year’s comparable period.

Morris Goldfarb, G-III’s Chairman, Chief Executive Officer and President, said, “We designed and delivered compelling product and maintained good sell-throughs, in addition to building a strong order book for the upcoming fall season. Across our business, we met and exceeded plans for both sales and margins. Our performance included powerful organic growth across the full range of our wholesale businesses, led by Calvin Klein and dress businesses such as Eliza J and Vince Camuto. The momentum continued with respect to our turnaround and repositioning of the G.H. Bass business that we acquired in November 2013.”

Mr. Goldfarb concluded, “We are pleased to continue to report improved results while also delivering value to our shareholders. We are continuing to demonstrate our ability to simultaneously drive organic sales growth, further diversify our business, and enhance our profitability.”
