Basis of Presentation

GameStop Corp. (together with its predecessor companies, “GameStop,” “we,” “us,” “our,” or the “Company”), a Delaware corporation, is the world’s largest multichannel video game retailer. The Company sellsWe sell new and pre-owned video game hardware, physical and digital video game software, accessories, as well as PC entertainment software, new and pre-owned mobile and consumer electronics products and other merchandise. The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting only of normal, recurring adjustments) which are, in theour opinion, of the Company’s management, necessary for a fair presentation of the information for the periods presented. These unaudited condensed consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the instructions to Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all disclosures required under GAAP for complete consolidated financial statements. These condensed consolidated financial statements should be read in conjunction with the Company’sour annual report on Form 10-K for the 53 weeks ended February 2, 2013 (“fiscal 2012”). The preparation of financial statements in conformity with GAAP requires managementus to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. In preparing these financial statements, management haswe have made itsour best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. Changes in the estimates and assumptions used by managementus could have a significant impact on the Company’sour financial results. Actual results could differ from those estimates.

Due to the seasonal nature of the business, the results of operations for the 1326 weeks ended May 4,August 3, 2013 are not indicative of the results to be expected for the 52 weeks ending February 1, 2014 (“fiscal 2013”).

Certain reclassifications have been made to conform the prior period data to the current interim period presentation.Restricted Cash

Restricted cash of $10.4 million, $12.0 million and $13.4 million as of August 3, 2013, July 28, 2012 and February 2, 2013, respectively, consists primarily of bank deposits serving as collateral for bank guarantees issued on behalf of our foreign subsidiaries and is included in other noncurrent assets in our condensed consolidated balance sheets.

Recently AdoptedIssued Accounting Standards

In July 2013, accounting standards update (“ASU”) 2013-11“Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” was issued requiring an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as either a reduction to a deferred tax asset or separately as a liability depending on the existence, availability and/or use of an operating loss carry forward, a similar tax loss, or a tax credit carry forward. This ASU will be effective for us beginning the first quarter of 2014. We do not expect that this ASU will have an impact on our condensed consolidated financial statements as we currently do not have any unrecognized tax benefits in the same jurisdictions in which we have tax loss or credit carryovers.

GAMESTOP CORP.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

In March 2013, an accounting standard updateASU 2013-05“Foreign Currency Matters (Topic 830)” was issued providing guidance with respect to the release of cumulative translation adjustments into net income when a parent company sells either a part or all of an investment in a foreign entity. The accounting standard updateASU requires the release of cumulative translation adjustments when a company no longer holds a controlling financial interest in a foreign subsidiary or a group of assets that constitutes a business within a foreign entity. This accounting standard update isASU will be effective for fiscal yearsus beginning after December 15, 2013, with early adoption permitted. The Company isthe first quarter of 2014. We are evaluating the effect of this accounting standard update,ASU, but doesdo not expect it to have a significant impact on itsour condensed consolidated financial statements.

In February 2013, an accounting standard updateASU 2013-02“Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” was issued regarding disclosure of amounts reclassified out of accumulated other comprehensive income by component. An entity is required to present either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

about those amounts. This accounting standard update isASU was effective for the Company’sour annual and interim periods beginning in fiscal 2013. The accounting standard updateASU had no effect on the Company’sour condensed consolidated financial statements.

In July 2012, an accounting standard update was issued related to testing indefinite-lived intangible assets for impairment. The purpose of the update is to simplify the guidance for testing indefinite-lived intangible assets for impairment and the update permits entities to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. Unless an entity determines, through its qualitative assessment, that it is more likely than not that an indefinite-lived intangible asset is impaired, it would not be required to calculate the fair value of the asset. This standard is effective for annual and interim impairment tests of indefinite-lived intangible assets performed in fiscal years beginning after September 15, 2012, and early adoption is permitted. This standard did not have an impact on our annual indefinite-lived asset impairment testing process in fiscal 2012 as we did not elect to perform a qualitative assessment. The adoption of this guidance may result in a change in how we perform our goodwill impairment assessment; however, it is not expected to have a material impact on our consolidated financial statements.

The following is a summary of the stock-based awards granted during the periods indicated:

For stock options granted, the Company records share-basedwe record stock-based compensation expense in earnings based on the grant-date fair value. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. This valuation model requires the use of subjective assumptions, including expected option life, expected volatility, expected dividend yield and expected employee forfeiture rate. The Company usesWe use historical data to estimate the option life, dividend yield and the employee forfeiture rate, and usesuse historical volatility when estimating the stock price volatility. ThereThe following assumptions were noused with respect to the stock options granted during the 13 weeks ended April 28, 2012. During the 13 weeks ended May 4, 2013, 457 thousand options of Class A Common Stock were granted with a fair value of $7.10 per common share, using the following assumptions:granted:

The stock options granted become exercisable ratably over a three-year period, commencing one year after the grant date, subject to continued service to the Company, and expire in February 2023, or ten years after the grant date.

In the 13 weeks ended May 4, 2013 and April 28, 2012, the Company included compensation expense relating to stock option grants of $0.2 million and $0.7 million, respectively, in selling, general and administrative expenses in the accompanying condensed consolidated statements of operations. As of May 4, 2013, the unrecognized compensation expense related to the unvested portion of our stock options was $3.0 million, which is expected to be recognized over a weighted average period of 2.8 years. The total intrinsic value of options exercised during the 13 weeks ended May 4, 2013 and April 28, 2012 was $10.6 million and $0.4 million, respectively.

During the 13 weeks ended May 4, 2013, 1.2 million shares of restricted stock were granted with a fair value of $24.82 per common share. Of these restricted shares, 614 thousand shares vest in equal annual installments over three years, 262 thousand shares are performance-based and 303 thousand shares vest in full in

Of the 262 thousand performance-based restricted shares granted during the 13 weeks ended May 4, 2013, 131 thousand shares will be measured following the completion of fiscal 2013 with the portion earned vesting in equal annual installments over three years. The remaining 131 thousand shares will be measured following the completion of the 52 weeks ending January 30, 2016. These grants will vest immediately upon measurement to the extent earned. Shares subject to performance measures may generally be earned in greater or lesser percentages if targets are exceeded or not achieved by specified amounts. During the 13 weeks ended April 28, 2012, 1.4 million shares of restricted stock were granted with a fair value of $23.73 per common share. Of these shares, 770 thousand vest in equal annual installments over three years and 626 thousand shares are subject to performance measures. Of the performance related restricted shares granted, 126 thousand vest in equal annual installments, to the extent earned, over three years subject to performance targets based on fiscal 2012 operating results. Based on actual fiscal 2012 operating results, only 101 thousand of these performance-based shares were earned. The remaining 500 thousand shares of performance-based restricted shares granted are subject to performance targets which will be measured following the completion of the 52 weeks ending January 31, 2015.

Recurring Fair Value Measurements and Derivative Financial Instruments

The Company defines fairFair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value accounting guidance applies to our forward exchange contracts, foreign currency options and cross-currency swaps (together, the “Foreign Currency Contracts”), Company-owned life insurance policies with a cash surrender value and certain nonqualified deferred compensation liabilities that are measured at fair value on a recurring basis in periods subsequent to initial recognition.

GAMESTOP CORP.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Fair value accounting guidance requires disclosures that categorize assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1 for the asset or liability, either directly or indirectly through market-corroborated inputs. Level 3 inputs are unobservable inputs for the asset or liability reflecting our assumptions about pricing by market participants.

We value our Foreign Currency Contracts, Company-owned life insurance policies with cash surrender values and certain nonqualified deferred compensation liabilities based on Level 2 inputs using quotations provided by major market news services, such as Bloomberg, and The Wall Street Journal, and industry-standard models that consider various assumptions, including quoted forward prices, time value, volatility factors, and contractual prices for the underlying instruments, as well as other relevant economic measures. When appropriate, valuations are adjusted to reflect credit considerations, generally based on available market evidence.

The following table provides the fair value of our assets and liabilities measured at fair value on a recurring basis and recorded on our condensed consolidated balance sheets (in millions):

The Company uses

We use Foreign Currency Contracts to manage currency risk primarily related to intercompany loans denominated in non-functional currencies and certain foreign currency assets and liabilities. These Foreign Currency Contracts are not designated as hedges and, therefore, changes in the fair values of these derivatives are recognized in earnings, thereby offsetting the current earnings effect of the re-measurement of related intercompany loans and foreign currency assets and liabilities. The total gross notional value of derivatives related to our Foreign Currency Contracts was $686.7$692.3 million and $447.9$576.4 million as of May 4,August 3, 2013 and

Nonrecurring Fair Value Measurements

In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company recordswe record certain assets and liabilities at fair value on a nonrecurring basis as required by GAAP. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges. The CompanyWe did not record any significant impairment charges related to assets measured at fair value on a nonrecurring basis during the 1326 weeks ended May 4,August 3, 2013 and Aprilor July 28, 2012.

On January 4, 2011, the Companywe entered into a $400 million credit agreement (the “Revolver”), which amended and restated, in its entirety, the Company’sour prior credit agreement entered into in October 2005 (the “Credit Agreement”). The Revolver provides for a five-year, $400 million asset-based facility, including a $50 million letter of credit sublimit, secured by substantially all of the Company’s and its domestic subsidiaries’ assets. The Company hasWe have the ability to increase the facility, which matures in January 2016, by $150 million under certain circumstances. The extension of the Revolver to 2016 reduces our exposure to potential tightening or other adverse changes in the credit markets.

The availability under the Revolver is limited to a borrowing base which allows the Companyus to borrow up to 90% of the appraisal value of the inventory, in each case plus 90% of eligible credit card receivables, net of certain reserves. Letters of credit reduce the amount available to borrow by their face value. The Company’sOur ability to pay cash dividends, redeem options and repurchase shares is generally permitted, except under certain circumstances, including if Revolver excess availability is less than 20%, or is projected to be within 12 months after such

payment. In addition, if Revolver usage is projected to be equal to or greater than 25% of total commitments during the prospective 12-month period, the Company iswe are subject to meeting a fixed charge coverage ratio of 1.1:1.0 prior to making such payments. In the event that excess availability under the Revolver is at any time less than the greater of (1) $40.0 million or (2) 12.5% of the lesser of the total commitment or the borrowing base, the Companywe will be subject to a fixed charge coverage ratio covenant of 1.1:1.0.

The Revolver places certain restrictions on the Companyus and itsour subsidiaries, including limitations on asset sales, additional liens, investments, loans, guarantees, acquisitions and the incurrence of additional indebtedness. Absent consent from itsour lenders, the Companywe may not incur more than $750 million of additional unsecured indebtedness to be limited to $250 million in general unsecured obligations and $500 million in unsecured obligations to finance acquisitions valued at $500 million or more.

The per annum interest rate under the Revolver is variable and is calculated by applying a margin (1) for prime rate loans of 1.25% to 1.50% above the highest of (a) the prime rate of the administrative agent, (b) the federal funds effective rate plus 0.50% or (c) the London Interbank Offered (“LIBO”) rate for a 30-day interest period as determined on such day plus 1.00%, and (2) for LIBO rate loans of 2.25% to 2.50% above the LIBO rate. The applicable margin is determined quarterly as a function of the Company’sour average daily excess availability under the facility. In addition, the Company iswe are required to pay a commitment fee of 0.375% or 0.50%, depending on facility usage, for any unused portion of the total commitment under the Revolver. As of May 4,August 3, 2013, the applicable margin was 1.25% for prime rate loans and 2.25% for LIBO rate loans, while the required commitment fee was 0.50% for the unused portion of the Revolver.

The Revolver provides for customary events of default with corresponding grace periods, including failure to pay any principal or interest when due, failure to comply with covenants, any material representation or warranty made by the Companyus or the borrowers proving to be false in any material respect, certain bankruptcy, insolvency or receivership events affecting the Companyus or itsour subsidiaries, defaults relating to certain other indebtedness, imposition of certain judgments and mergers or the liquidation of the Company or certain of its subsidiaries. During the 26 weeks ended August 3, 2013, we borrowed $130.0 million under the Revolver and repaid $80.0 million, leaving an outstanding balance of $50.0 million as of August 3, 2013. During the 26 weeks ended July 28, 2012, we borrowed and repaid $36.0 million under the Revolver. Average borrowings under the Revolver for the 13 weeks and 26 weeks ended August 3, 2013 were $44.2 million and $22.1 million, respectively. Our average interest rates on those outstanding borrowings for the 13 weeks and 26 weeks ended August 3, 2013 were 2.9% for both periods. As of May 4,August 3, 2013, total availability under the Revolver was $340.2$253.3 million, there were nowas $50.0 million of borrowings outstanding and standby letters of credit outstanding totaled $9.0 million. We are currently in compliance with the requirements of the Revolver.

In September 2007, the Company’sour Luxembourg subsidiary entered into a discretionary $20.0 million Uncommitted Line of Credit (the “Line of Credit”) with Bank of America. There is no term associated with the Line of Credit and Bank of America may withdraw the facility at any time without notice. The Line of Credit is available to the Company’sour foreign subsidiaries for use primarily as a bank overdraft facility for short-term liquidity needs and for the issuance of bank guarantees and letters of credit to support operations. As of May 4,August 3, 2013, there were no cash overdrafts outstanding under the Line of Credit and bank guarantees outstanding totaled $4.8$4.6 million.

We accrue for the effects of uncertain tax positions and the related potential penalties and interest. Our recorded liability for unrecognized tax benefits decreased by $8.5 million during the 13 weeks ended August 3, 2013 and by $17.9 million during the 26 weeks ended August 3, 2013. The decrease in the liability for unrecognized tax benefits was primarily the result of payments made to settle certain U.S. federal income tax items and did not have a material impact on our income tax provision. There were no net material adjustments to our recorded liability for unrecognized tax benefits during the 13 and 26 weeks ended May 4, 2013.July 28, 2012. It is reasonably possible that the amount of the unrecognized tax benefit with respect to certain of our unrecognized tax positions could significantly increase or decrease during the next 12 months. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.

The income tax provisions for the 13 weeks and 26 weeks ended May 4,August 3, 2013 and AprilJuly 28, 2012 are based upon management’s estimate of the Company’sour annualized effective tax rate.
