New York, New York – December 4, 2013 – G-III Apparel Group, Ltd. (NasdaqGS: GIII) today announced operating results for the third quarter of fiscal 2014 that ended October 31, 2013.

For the third quarter ended October 31, 2013, G-III reported that net sales increased by 23% to a record $668.7 million compared to $543.5 million in the year-ago period.

The Company’s net income for the third quarter increased by 23% to $59.6 million, or $2.85 per diluted share, compared to net income of $48.3 million, or $2.37 per diluted share, in the prior year’s comparable period. On an adjusted basis, excluding expenses in the quarter ended October 31, 2013 associated with the Company’s acquisition of G.H. Bass & Co. and other potential transactions and in the quarter ended October 31, 2012 associated with the acquisition of Vilebrequin, Non-GAAP net income per diluted share for the third quarter increased 19% to $2.88 compared to $2.43 in the prior year’s third quarter. A reconciliation of GAAP net income per share to Non-GAAP net income per share is presented in a table accompanying the condensed financial statements included in this release.

Morris Goldfarb, G-III’s Chairman, Chief Executive Officer and President, said, “We are pleased to report excellent results in our key third quarter season driven by across-the-board strength in our business. In our wholesale business, great product design, compelling price and value, and a portfolio of strong brands drove our business to record levels of both net sales and net income per share.”

Mr. Goldfarb continued, “In our specialty retail business, we continued a powerful comp sales trend in our Wilsons’ business and proceeded with our full-priced store test in time for the holiday season. In addition, we acquired G.H. Bass & Co., which is an iconic brand with great potential and a business that should integrate well into our existing retail platform.”

Mr. Goldfarb concluded, “We have had consistent growth over the last several years and our opportunities have never had greater scale or wider scope than they do today. Our team and culture have never been stronger. We look forward to the work ahead and to the continuing opportunity we have to create value for our shareholders.”

Outlook

The Company today revised its prior guidance for the full fiscal 2014 year ending January 31, 2014 to reflect its strong third quarter financial performance and the expected results from G.H. Bass & Co. in the fourth fiscal quarter. The Company is now forecasting net sales of approximately $1.73 billion compared to its previous guidance of $1.61 billion. It now expects net income in the range of $72.0 million to $74.0 million, or $3.47 to $3.57 per diluted share, compared to its previous guidance of net income between $68.6 million and $70.6 million, or a range between $3.30 and $3.40 per diluted share. The revised upward guidance for fiscal 2014 includes the expenses associated with the acquisition of G.H. Bass and other potential transactions incurred through October 31, 2013. The Company’s full year guidance of $3.47 to $3.57 per diluted share includes a projected net loss of $0.10 to $0.15 per share in the fourth quarter in connection with the operations of its newly acquired G.H. Bass & Co. business. The full year estimates exclude the impact of any purchase price accounting adjustments relating to the acquisition of G.H. Bass.

The Company is forecasting Non-GAAP net income per diluted share for the full 2014 fiscal year to be in the range of $3.50 to $3.60 compared to $2.92 for the 2013 fiscal year.

The Company is now projecting adjusted EBITDA for fiscal 2014 to increase approximately 22% to 25% to between $139.0 million and $142.5 million compared to adjusted EBITDA of $114.0 million in fiscal 2013 and an increase from its previous guidance of adjusted EBITDA of between approximately $132.3 million and $135.4 million.

The forecasted Non-GAAP net income per share and forecasted adjusted EBITDA for the full fiscal 2014 year reflect adjustments that exclude any expenses associated with the Company’s acquisition of G.H. Bass & Co. and other potential transactions incurred through October 31, 2013.

Non-GAAP net income per diluted share and adjusted EBITDA should be evaluated in light of the Company’s financial results prepared in accordance with U.S. GAAP. Reconciliations of forecasted

GAAP net income per share to forecasted Non-GAAP net income per share and of GAAP net income to adjusted EBITDA are included in tables accompanying the condensed financial statements in this release.

Bass and other potential transactions in the fiscal 2014 periods. The non-GAAP information in the tables above reflects an adjustment for expenses and integration costs associated with the (i) Vilebrequin acquisition that were incurred through fiscal 2013 and (ii) G. H. Bass acquisition and other potential transactions that were incurred through October 31, 2013, but does not reflect expenses and integration costs that may be incurred in the fourth quarter of this fiscal year. Management believes that this non-GAAP financial measure provides meaningful supplemental information regarding our performance by excluding discrete expenses and integration costs associated with these acquisitions and potential transactions that are not indicative of our core business operating results. Management uses this non-GAAP financial measure to assess our performance on a comparative basis and believes that that it is also useful to investors to enable them to assess our performance on a comparative basis across historical periods and facilitate comparisons of our operating results to those of our competitors.
