FOR IMMEDIATE RELEASE

PACIFIC SUNWEAR ANNOUNCES FIRST QUARTER OPERATING
RESULTS; ISSUES SECOND QUARTER GUIDANCE

ANAHEIM, CA/May 24, 2011 — Pacific Sunwear of California, Inc. (NASDAQ: PSUN, the “Company”), announced today that net sales for the first quarter of fiscal 2011 ended April 30, 2011 were $186 million, a decrease of 2% from net sales of $190 million for the first quarter of fiscal 2010 ended May 1, 2010. Total Company same-store sales increased 1% during the first quarter of fiscal 2011.

The Company reported a net loss of $31 million, or $(0.48) per share, for the first quarter of fiscal 2011 compared to a net loss of $31 million, or $(0.47) per share, for the first quarter of fiscal 2010. Results for the first quarter of fiscal 2011 reflect the continuing impact of a valuation allowance against the Company’s deferred tax assets. On a comparable non-GAAP basis, using a normalized 36.5% income tax rate, the Company’s non-GAAP net loss for the quarter was $20 million, or $(0.30) per share.

“Getting back to a positive comp is certainly an important step in the turnaround of our business,” said Gary H. Schoenfeld, President and Chief Executive Officer. “As our new team comes together, we have initiated a number of important changes in merchandising, marketing and in-store experience that customers are beginning to respond to.”

Financial Outlook for Second Fiscal Quarter of 2011

The Company’s guidance range for the second quarter of fiscal 2011 contemplates a GAAP net loss per share of $(0.36) to $(0.46) which reflects the continuing impact of maintaining a valuation allowance against deferred tax assets and a low effective tax rate. On a non-GAAP basis, using a normalized effective income tax rate of 36% to 37%, the Company’s guidance range translates to a net loss of $(0.22) to $(0.29) per share for the second quarter of fiscal 2011. The forecasted second quarter GAAP guidance range is based on the following major assumptions:

	•		Same-store sales of -3% to +2%;
	•		Gross margin rate, including buying, distribution and occupancy, of 19% to 21%;
	•		SG&A expenses in the range of $67 million to $69 million; and
	•		Minimal income tax expense as the Company no longer records income tax benefits against its operating losses.

ABOUT NON-GAAP FINANCIAL MEASURES

The accompanying press release dated May 24, 2011 contains non-GAAP financial measures. These non-GAAP financial measures include non-GAAP net loss and non-GAAP net loss per share for the first quarter of fiscal 2011 and non-GAAP net loss per share guidance for the second quarter of fiscal 2011. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same names and may differ from non-GAAP financial measures with the same or similar names that are used by other companies. The Company computes non-GAAP financial measures using the same consistent method from quarter to quarter and year to year. The Company may consider whether other significant items that arise in the future should be excluded from the non-GAAP financial measures. The Company has excluded the following item from all of its non-GAAP financial measures:

•

Deferred tax asset valuation allowance charges

The Company believes that these non-GAAP financial measures provide meaningful supplemental information regarding the Company’s operating results primarily because they exclude amounts that are not considered part of ongoing operating results when planning and forecasting and when assessing the performance of the organization, individual operating segments or its senior management. In addition, the Company believes that non-GAAP financial information is used by analysts and others in the investment community to analyze the Company’s historical results and in providing estimates of future performance and that failure to report these non-GAAP measures, could result in confusion among analysts and others and create a misplaced perception that the Company’s results have underperformed or exceeded expectations.
