Quiksilver Reports Fiscal 2012 Third Quarter Financial Results

—Revenues Increase to $512.4 Million, Up 8% in Constant Currency—

Huntington Beach, California, Sept. 6, 2012—Quiksilver, Inc. (NYSE:ZQK) today announced operating results for the third fiscal quarter ended July 31, 2012.

“During the quarter, we continued to make solid progress on our three long-term initiatives, which are strengthening our brands, expanding our business and driving operational efficiencies throughout the business,” said Robert B. McKnight, Jr., Chairman of the Board, Chief Executive Officer and President of Quiksilver, Inc.

“From a brand perspective, we launched integrated social media marketing campaigns, hosted the premier skate tour in the industry and had outstanding team-rider success in surfing,” continued McKnight. “From a growth standpoint, our business performed admirably. DC posted sales growth of 16% and e-commerce sales more than doubled. European sales grew modestly, which positions us well compared with our peers. In the area of operational efficiencies, we made tough decisions during the quarter regarding SG&A, including effecting staff eliminations in all our regions, as well as reductions in other operating expenses. Also, after implementing our new ERP system in the Americas in the second quarter, we kicked off our European ERP rollout in the third quarter, which will drive efficiencies by helping to integrate our operations and standardize our business processes globally. I applaud our team’s tenacity during this time of transformation and believe we are focusing on the right actions to strengthen our business and drive sustainable value.”

Fiscal Third Quarter Review:

All comparisons are between the third quarter of fiscal 2012 and the third quarter of fiscal 2011. A reconciliation of GAAP results to pro-forma results is provided in the accompanying tables.

Revenues grew 2% to $512.4 million compared with $503.3 million, and grew 8%, or $38 million, in constant currency.

Please refer to the accompanying tables to better understand the impact of foreign currency exchange rates on revenue trends.

SG&A increased to $225.8 million compared with $221.2 million, up 10 basis points as a percentage of sales, primarily driven by $3.9 million of costs associated with staff eliminations and restructuring.

Pro-forma Adjusted EBITDA was $51.2 million compared with $52.7 million, with the decline largely driven by the contraction in gross margin mentioned above.

Net income was $12.6 million, or $0.07 per diluted share, compared with net income of $10.4 million, or $0.06 per diluted share.

Pro-forma income, which excludes $3.8 million of net after-tax restructuring charges and asset impairments, was $16.4 million, or $0.09 per diluted share, compared with pro-forma income of $10.4 million, or $0.06 per diluted share.

Definition of Adjusted EBITDA:

Adjusted EBITDA is defined as net income (loss) attributable to Quiksilver, Inc. before (i) interest expense, (ii) income tax expense, (iii) depreciation and amortization, (iv) non-cash stock-based compensation expense and (v) asset impairments. Adjusted EBITDA is not defined under generally accepted accounting principles (“GAAP”), and it may not be comparable to similarly titled measures reported by other companies. We use Adjusted EBITDA, along with other GAAP measures, as a measure of profitability because Adjusted EBITDA helps us to compare our performance on a consistent basis by removing from our operating results the impact of our capital structure, the effect of operating in different tax jurisdictions, the impact of our asset base, which can differ depending on the book value of assets, the accounting methods used to compute depreciation and amortization, the existence or timing of asset impairments and the effect of non-cash stock-based compensation expense. We believe EBITDA is useful to investors as it is a widely used measure of performance and the adjustments we make to EBITDA provide further clarity on our profitability. We remove the effect of non-cash stock-based compensation from our earnings which can vary based on share price, share price volatility and the expected life of the equity instruments we grant. In addition, this stock-based compensation expense does not result in cash payments by us. We remove the effect of asset impairments from Adjusted EBITDA for the same reason that we remove depreciation and amortization as it is part of the impact of our asset base. Adjusted EBITDA has limitations as a profitability measure in that it does not include the interest expense on our debts, our provisions for income taxes, the effect of our expenditures for capital assets and certain intangible assets, the effect of non-cash stock-based compensation expense and the effect of asset impairments.

SUPPLEMENTAL EXCHANGE RATE INFORMATION

(Unaudited)

In order to better understand growth rates in our operating segments, we make reference to constant currency. Constant currency reporting improves visibility into actual growth rates as it adjusts for the effect of changing foreign currency exchange rates from period to period. Constant currency is calculated by taking the ending foreign currency exchange rate (for balance sheet items) or the average foreign currency exchange rate (for income statement items) used in translation for the current period and applying that same rate to the prior period. The following table presents revenues by segment in both historical currency and constant currency for the three months ended July 31, 2012 and 2011 (in thousands):
