New York, New York – December 2, 2015 – G-III Apparel Group, Ltd. (NasdaqGS: GIII) today announced operating results for the third quarter of fiscal 2016 that ended October 31, 2015. All share and per share data in this release have been retroactively adjusted to reflect the two-for-one stock split effective May 1, 2015.

For the third quarter ended October 31, 2015, G-III reported that net sales increased by 12% to $910 million from $812 million in the year-ago period.

The Company’s net income for the third quarter increased to $87.2 million, or $1.87 per diluted share, from $80.6 million, or $1.76 per diluted share, in the prior year’s comparable period. On an adjusted basis, excluding items resulting in other income equal to $0.02 per share in the quarter ended October 31, 2015 and $0.22 per share in the quarter ended October 31, 2014, non-GAAP net income per diluted share for the third quarter increased to $1.85 from $1.54 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 a strong third quarter. Our organic sales and profit increase clearly differentiate us as a leader in our

industry. We achieved this performance in a challenging market environment. Although outerwear is off to a slow start at retail, our dress, sportswear and handbag businesses performed well in the quarter.”

Mr. Goldfarb continued, “We have made a guidance revision for the full year to reflect expected softness in consumer spending and reduced traffic in the fourth quarter. That said, we do have many sources of strength throughout our business. We continue to drive diversification across channels, supported by a strong brand portfolio and great execution. We remain focused on continuing to implement successful business strategies and creating value for our shareholders. The share repurchase program approved by our Board reflects confidence in our business. It is also consistent with our strategy of providing value to our stockholders while maintaining flexibility to use our financial resources to pursue new opportunities to grow our business.”

Share Repurchase Program

G-III announced today that its Board of Directors had reapproved and increased the previously authorized share repurchase program. There were 3,750,000 shares available under the prior program which the Board has increased to 5,000,000 shares. The timing and actual number of shares repurchased, if any, will depend on a number of factors, including market conditions and prevailing stock prices, and are subject to compliance with certain covenants contained in our loan agreement. Share repurchases may take place on the open market, in privately negotiated transactions or by other means, and would be made in accordance with applicable securities laws. The Company currently has approximately 45,537,000 shares of common stock outstanding.

Outlook

The Company today revised its prior guidance for the full fiscal year ending January 31, 2016. The Company is continuing to forecast net sales of approximately $2.40 billion. It now expects net income to be between $124 million and $131 million, or a range between $2.67 and $2.82 per diluted share, compared to its previous guidance of net income between $129 million and $134 million, or a range between $2.78 and $2.88 per diluted share, and to net income of $110.4 million, or $2.48 per diluted share, in the fiscal year ended January 31, 2015. In addition, the current annual guidance includes other income items included in our results for the third quarter equal to $0.02 per share.

The Company is forecasting non-GAAP net income per diluted share for the full 2016 fiscal year to increase by 17% to 24% to between $2.65 and $2.80 compared to $2.26 for the 2015 fiscal year.

The Company is now projecting adjusted EBITDA for fiscal 2016 to increase between 22% and 28% to between approximately $227 million and $238 million compared to adjusted EBITDA of $186.6 million in fiscal 2015 and from its previous guidance of adjusted EBITDA of between approximately $237 million and $245 million.

The forecasted and actual non-GAAP net income per share and forecasted and actual adjusted EBITDA reflect adjustments that exclude (i) items resulting in other income in fiscal 2016 equal to $0.02 per share, and (ii) items resulting in other income in fiscal 2015 equal to $0.22 per share, net of taxes.

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 and actual GAAP net income per share to forecasted and actual 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.

RECONCILIATION OF FORECASTED AND ACTUAL GAAP NET INCOME PER SHARE TO

FORECASTED AND ACTUAL NON-GAAP NET INCOME PER SHARE

(Unaudited)

Non-GAAP diluted net income per share is a “non-GAAP financial measure” that excludes (i) items resulting in other income in fiscal 2016 which consists of the reduction of the estimated contingent consideration payable in connection with the acquisition of Vilebrequin and (ii) items resulting in other income in fiscal 2015 which consists of (a) the sale of the right to operate Calvin Klein Performance stores in Asia, including the sale of the Company’s interest in a joint venture that operated Calvin Klein Performance stores in China and expenses associated with this other income incurred in the fourth quarter of fiscal 2015, (b) the reduction of a portion of the estimated contingent consideration payable in connection with the acquisition of Vilebrequin, and (c) the early extinguishment of debt due to the seller of Vilebrequin for an amount less than the principal amount of this debt. Management believes that this non-GAAP financial measure provides meaningful supplemental information regarding our performance by excluding items of other income 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 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. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

RECONCILIATION OF FORECASTED AND ACTUAL NET INCOME TO FORECASTED AND ACTUAL ADJUSTED EBITDA

(In thousands)

(Unaudited)

Adjusted EBITDA is a “non-GAAP financial measure” which represents earnings before depreciation and amortization, interest and financing charges, net, and income tax expense and excludes (i) items resulting in other income in fiscal 2016 which consists of the reduction of the estimated contingent consideration payable in connection with the acquisition of Vilebrequin and (ii) items resulting in other income in fiscal 2015 which consists of (a) the sale of the right to operate Calvin Klein Performance stores in Asia, including the sale of the Company’s interest in a joint venture that operated Calvin Klein Performance stores in China and expenses associated with this other income incurred in the fourth quarter of fiscal 2015, (b) the reduction of a portion of the estimated contingent consideration payable in connection with the acquisition of Vilebrequin, and (c) the early extinguishment of debt due to the seller of Vilebrequin for an amount less than the principal amount of this debt. Adjusted EBITDA is being presented as a supplemental disclosure because management believes that it is a common measure of operating performance in the apparel industry. Adjusted EBITDA should not be construed as an alternative to net income as an indicator of the Company’s operating performance, or as an alternative to cash flows from operating activities as a measure of the Company’s liquidity, as determined in accordance with generally accepted accounting principles.
