Ladies and Gentlemen:

We are acting as counsel to GameStop Corp., a Delaware corporation (the “Company”), in connection with the issuance and sale of up to 20,000,000 shares (the “Shares”) of the Company’s Class A Common Stock, par value $0.001 per share, all of which are authorized but heretofore unissued shares to be offered and sold by the Company pursuant to the Registration Statement on Form S-3 (File No. 333-279472) (the “Registration Statement”), filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), on May 17, 2024, which became effective automatically as of the date of filing, including the base prospectus contained therein, dated May 17, 2024 (the “Base Prospectus”), as supplemented by the prospectus supplement dated September 10, 2024, relating to the offer and sale of the Shares (as so supplemented, the “Prospectus”) pursuant to the Open Market Sale Agreement^SM (the “Sales Agreement”), dated as of May 17, 2024, by and between the Company and Jefferies LLC.

In connection with this opinion letter, we have examined (i) the Registration Statement, (ii) the Prospectus, (iii) the Third Amended and Restated Certificate of Incorporation of the Company, as amended, (iv) the Fifth Amended and Restated Bylaws of the Company, as amended, (v) certain resolutions of the board of directors of the Company (the “Board”) relating to the issuance, sale and registration of the Shares and (vi) the Sales Agreement. In addition, we have examined and relied upon such corporate records of the Company, and have made such examination of law, as we have deemed necessary or appropriate for purposes of the opinions expressed below. As to certain factual matters, unless otherwise indicated, we have relied, to the extent we have deemed proper, on certificates of certain officers of the Company.

We have assumed for purposes of rendering the opinions set forth herein, without any verification by us, the genuineness of all signatures, the legal capacity of all natural persons to execute and deliver documents, the authenticity and completeness of documents submitted to us as originals, the completeness and conformity with authentic original documents of all documents submitted to us as copies, and that all documents, books and records made available to us by the Company are accurate and complete.

Based upon, subject to and limited by the foregoing, we are of the opinion that the Shares have been duly and validly authorized by the Company and, upon issuance, delivery and payment therefor in the manner contemplated by the Registration Statement and the Prospectus, will be legally issued, fully paid and nonassessable.
