THE WET SEAL, INC. ANNOUNCES SECOND

QUARTER FISCAL 2012 RESULTS AND PROVIDES

FINANCIAL OUTLOOK FOR THIRD QUARTER 2012

Announces a Return to its Proven Fast Fashion

Merchandising Approach to Improve Performance

Addresses Strategic Initiatives to Enhance

Shareholder Value

FOOTHILL RANCH, CA, August 21, 2012 (BUSINESS WIRE) – The Wet Seal, Inc. (Nasdaq: WTSLA), a leading specialty retailer to young women, announced results for its fiscal second quarter ended July 28, 2012 and provided its financial outlook for the third quarter of fiscal 2012. The Company also announced that it is refocusing on its proven fast fashion merchandising approach to improve overall performance and is implementing several strategic initiatives to enhance shareholder value.

Hal Kahn, Chairman of the Board of The Wet Seal, Inc., said: “The end of the second quarter was the beginning of an important transition period for Wet Seal as we made the decision to return to our core expertise of fast fashion merchandising. We began taking aggressive actions to refocus our strategy in a way that we believe will address the issues that resulted in this disappointing quarter. We are returning to merchandising to a broader demographic, including the young teen customer, sourcing a wider variety of product more directly from fast fashion vendors, committing to merchandise purchases closer to time of need, and focusing our price points on our core customer, which long supported success at the Company.”

Mr. Kahn added: “As we execute on this return to our core expertise, we expect it will take several months to begin to realize the impact of the transition in our merchandise and in-store marketing. So, while we expect continued weak performance through the third quarter, we believe that this trend will bottom out in the coming months and that we will begin to see clear signs of improvement in the fourth quarter – ultimately returning to a level of sales and earnings that this strategy has driven for many years. As a result, we believe the Company will be positioned to stabilize the business during the holiday season and 2013.”

For the second quarter:

Mr. Kahn said: “These results are well below where we believe the Company is capable of performing when we have the right fast fashion merchandise mix in our stores. We have a seasoned team of merchandisers and senior professionals that have many years of experience successfully executing fast fashion strategies at Wet Seal, and we believe that this return to what we know best will revitalize our results in the near term.”

Mr. Kahn continued: “While the Board will continue to have a dialogue with all of our investors and remains open to considering all strategic opportunities available to the business, we are confident that we have the team, resources and strong balance sheet required to successfully implement our strategy. During this period of transition, we have taken additional steps to ensure that we maintain the appropriate level of support and stability to ensure seamless execution of our fast fashion strategy and optimal value for all shareholders.”

CEO Transition and Interim Leadership

On July 23, 2012, the Board announced the departure of the Company’s Chief Executive Officer, Susan McGalla, after determining that the current business and economic environment called for a change in the Company’s transition toward a focused fashion merchandising strategy and a prompt return to its fast fashion merchandising strategy.

“We greatly appreciate Susan McGalla’s leadership during her tenure at The Wet Seal, and we are grateful for the contributions she made to the Company, particularly the efforts to improve brand appeal for a focused fashion merchandising strategy, and to build company infrastructure and a strong leadership team which should help Wet Seal as it moves forward,” Mr. Kahn said. “The lagging economic recovery and other pressures on retail sales made it necessary for us to change our strategy in a timely fashion. We wish Susan all the best in her future endeavors.”

The Company is currently being led by the Board-appointed Office of the Chairman, which includes Mr. Kahn, the Company’s non-executive Chairman, President and Chief Operating Officer Ken Seipel, and Chief Financial Officer Steve Benrubi. Mr. Kahn has assumed direct leadership responsibility for all merchandising and marketing functions at the Company. Mr. Kahn is a long-time member of the Board and has over 35 years of industry experience. He was previously the CEO of Macy’s East.

The Board has hired a leading executive recruiter, Korn/Ferry International, to assist in its search for a Chief Executive Officer. It is too early in the search process to establish a useful timetable for selection of a new Chief Executive Officer.

Review of Capital Plan and Strategic Initiatives

In addition to creating the new Office of the Chairman under Mr. Kahn’s leadership, the Company’s Board of Directors has appointed a Strategic Oversight Committee, comprised of Board members Sidney Horn, Kenneth Reiss and Henry Winterstern, which will be responsible for reviewing and making recommendations to the Board concerning the Company’s capital allocation as well as evaluating potential strategic initiatives to enhance shareholder value.

The Board has engaged the firms Guggenheim Securities, LLC and Peter J. Solomon Company, L.P. to act as financial advisors to the Company on a variety of issues, including an assessment of the Company’s capital needs, cash balance and potential strategic options to enhance shareholder value. The Committee will consider the Company’s cash position in light of its recent negative financial performance, revised operational strategy and other potential strategic opportunities available to the Company. The Committee plans to provide timely updates to stakeholders on its significant decisions and actions, as warranted.

Employee Retention Plan

To retain the talent critical to executing the Company’s strategy and maximizing shareholder value, the Company has implemented an Employee Retention Plan for 35 employees.

Mr. Kahn said, “Wet Seal’s senior leadership and merchandising teams are very in tune with the Company’s target customer base and have extensive experience executing the fast fashion merchandising strategy we have relied on for many years. We believe it is critical to retain this talent base, and this retention plan will help provide stability and continuity for the Company during this important transition period.”

In addition, in recognition of the significant additional duties being assumed by Chairman Hal Kahn and members of the Board’s Strategic Oversight Committee, their compensation has been increased for a six month period.

Please see the Company’s Form 8-K filed today with the Securities and Exchange Commission for more details on the Employee Retention Plan and on changes in Director compensation.

Shareholder Rights Plan

The Board has adopted a short-term Shareholder Rights Plan (“Rights Plan”), which is scheduled to expire on June 30, 2013 and which is intended to protect all of the Company’s shareholders while the Company implements its return to its fast fashion strategy so that all shareholders will be able to realize the underlying value of their investment in the Company. The rights are not being distributed in response to any specific effort to acquire control of the Company. The rights are designed to ensure that the Board of Directors has sufficient time to consider any proposal and make sure that all stockholders receive fair and equal treatment in the event of any proposed takeover of the Company.

In addition, the Rights Plan will guard against partial tender offers, open market accumulations and other coercive tactics aimed at gaining control of the Company without paying all stockholders a full control premium for their shares. Under the Rights Plan, one preferred stock purchase right will be distributed for each share of Class A common stock held by stockholders of record on September 4, 2012.

Subject to limited exceptions, the Rights Plan will be triggered if a person or group acquires 10% or more of the outstanding Class A common stock of the Company or announces a tender offer for 10% or more of the Class A common stock.

Store Openings and Closings

During the quarter, the Company opened three stores and closed four stores at Wet Seal, with no store openings and two store closings at Arden B. At July 28, 2012, the Company operated 550 stores in 47 states and Puerto Rico, including 468 Wet Seal stores and 82 Arden B stores.

As the Company focuses on restoring its fast fashion merchandising strategy, it has deferred making additional new store opening commitments in its Wet Seal division through the remainder of fiscal 2012. The Company’s real estate plan is now expected to total from two to four net store closings at Wet Seal for fiscal 2012, which is a decrease from its prior plan of 20 to 22 net store openings. At Arden B, the Company’s real estate plan remains unchanged from its prior plan, with 15 to 20 net store closings during fiscal 2012. As a result, the Company estimates it will end fiscal 2012 with 468 to 470 Wet Seal stores and 66 to 71 Arden B stores.

Capital Expenditures and Depreciation

The Company invested $7.8 million in capital expenditures during the quarter, including $6.6 million for construction of new stores and remodeling of existing stores. The Company recognized tenant improvement allowances of $0.8 million, associated primarily with new store construction, which resulted in net capital expenditures for the quarter of $7.0 million.

Depreciation in the quarter totaled $4.6 million as compared to $4.8 million in the prior year period.

The Company now forecasts fiscal 2012 net capital expenditures will range between $20 million to $22 million, with between $14 million and $15 million for construction of new stores or remodeling of existing stores upon lease renewals and/or store relocations. This updated capital expenditure guidance represents a decrease from previous guidance for 2012 of $27 million to $29 million.

Income Taxes

The Company had an effective income tax rate of 36.7% for the quarter, which included the effect of a $0.3 million write-off of certain deferred tax assets in the quarter. The Company expects its effective rate for the fiscal year to be approximately 37.6%.

Third Quarter Fiscal 2012 Financial Outlook

For the third quarter of fiscal 2012, the Company estimates net loss per diluted share in the range of $0.13 to $0.16 versus net income per diluted share of $0.04 in the prior year third quarter.

The financial outlook is based on the following assumptions:

Segment Reporting (Unaudited)

The Company operates exclusively in the retail apparel industry in which it sells fashionable and contemporary apparel and accessories items, primarily through mall-based chains of retail stores, to female consumers with a young, active lifestyle. The Company has identified two operating segments (“Wet Seal” and “Arden B”) as defined under applicable accounting standards. E-commerce operations for Wet Seal and Arden B are included in their respective operating segments. Information for the 13 and 26 weeks ended July 28, 2012, and July 30, 2011, for the two reportable segments is set forth below (in thousands, except store counts and sales per square foot):

Exhibit B (Continued)

The “Corporate” column is presented solely to allow for reconciliation of store contribution amounts to consolidated operating income (loss), interest income or expense, net, and income (loss) before provision (benefit) for income taxes. Wet Seal and Arden B segment results include net sales, cost of sales, asset impairment and other direct store and field management expenses, with no allocation of corporate overhead or interest income and expense. Corporate expenses during the 13 and 26 weeks ended July 28, 2012, include $1.9 million of estimated CEO severance costs.

Wet Seal operating segment results during the 13 and 26 weeks ended July 28, 2012, and July 30, 2011, include $7.9 million, $10.6 million, $0.6 million and $0.8 million, respectively, of asset impairment charges.

Arden B operating segment results during the 13 and 26 weeks ended July 28, 2012, and July 30, 2011, include $1.1 million, $2.0 million, $0.5 million and $0.5 million, respectively, of asset impairment charges.

Exhibit C

Reconciliation of Non-GAAP Financial Measures to Most Directly Comparable Financial Measures

Included within this press release are references to net cash (used in) provided by operating activities, operating (loss) income, net (loss) income and net (loss) income per diluted share excluding the effect of certain adjustments and charges, which are measures not in compliance with accounting principles generally accepted in the United States of America, or “non-GAAP financial measures.” The following is a reconciliation of these non-GAAP financial measures to the applicable GAAP financial measures for the 13 week periods ended July 28, 2012, and July 30, 2011 (in millions, except for net (loss) income per diluted share):

Due to the relatively early timing of its second quarter of fiscal 2012 end date, the Company had not yet paid August 2012 rents and other landlord costs at that time, and instead paid those costs in the third quarter of fiscal 2012. As a result, the Company paid only two calendar months of these costs during the second quarter of fiscal 2012 versus typical payment of three calendar months of such costs within a fiscal quarter. Given this unique payment cycle, the Company believes the presentation of cash flows used in operating activities for the second fiscal quarter of 2012 assuming the typical three calendar months of rents and other landlord costs being paid is beneficial to investors’ understanding of the Company’s operating cash flows.

13

During the second quarter of fiscal 2012, the Company recorded significant estimated severance costs related to the departure of its Chief Executive Officer. Given the unique nature and substantial amount of these charges, the Company believes presentation of historical financial information excluding these charges to be beneficial to its investors.

From time to time, the Company determines the carrying values of certain of its long-lived assets are not supported by their anticipated future cash flows and, as a result, must record non-cash charges to impair these assets. The timing and magnitude of these charges can be sporadic, thus significantly affecting the reported financial results of the fiscal period in which they are recorded. Given the unique nature and sporadic timing of these charges, the Company consistently presents these charges as a separate line item within its statements of operations and, similarly, believes the presentation of its historical financial information excluding these non-cash charges to be beneficial to its investors.
