Recent Tax Law Changes

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the United States. The legislation includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Act and Jobs Act, modifications to the international tax framework and the restoration of favorable business tax provisions, such as 100% bonus depreciation and immediate expensing of domestic research and experimental expenditures. The legislation contains multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. While we are continuing to evaluate the full impact of the legislation, we do not expect the OBBBA to have a material effect on our estimated fiscal 2025 effective tax rate.

Recent Developments

On September 9, 2025, the Company issued a press release announcing that the Board declared a warrant dividend distribution (the “Warrant Distribution”) to the record holders of Common Stock, in the form of warrants to purchase Common Stock (the “Warrants”). The Warrants will be distributed on or around October 7, 2025 to the record holders of Common Stock as of the close of business on October 3, 2025 (the “Record Date”). Holders of Common Stock will receive one (1) warrant for each ten (10) shares of Common Stock, rounded down to the nearest whole number. Additionally, in lieu of an adjustment to the applicable conversion rate, holders of the Convertible Notes as of the Record Date will also receive, at the same time and on the same terms as holders of Common Stock, Warrants, without having to convert such holder’s Convertible Notes, as if such holder held a number of shares of Common Stock, equal to the product of (i) the conversion rate applicable to the Convertible Notes in effect on the Record Date and (ii) the aggregate principal amount (expressed in thousands) of Convertible Notes held by such holder on the Record Date. The expiration date of the warrants is expected to be on or about October 30, 2026 and will have an exercise price of $32.00 per share. We intend to apply for the warrants to be listed on the New York Stock Exchange to facilitate trading, which may begin under ticker symbol GME WS on the first day of trading following the distribution date.
