Item 1.01 Entry into a Material Definitive Agreement.

As previously disclosed, Brag House Holdings, Inc. (the “Company”) has entered into a Merger Agreement, dated as of October 12, 2025, by and among the Company, Brag House Merger Sub, Inc., a Delaware corporation (“Merger Sub”), and House of Doge Inc., a Texas corporation (“House of Doge”), as amended pursuant to Amendment No. 1 thereto dated as of November 26, 2025 and Amendment No 2. thereto dated as of February 2, 2026 (the “Merger Agreement”), pursuant to which, among other things, Merger Sub will merge with and into House of Doge (the “Merger”), with House of Doge surviving the Merger as a wholly owned subsidiary of the Company.

On March 26, 2026, the parties entered into an Amendment No. 3 to the Merger Agreement (the “Amendment”). The Amendment permits House of Doge to: (i) extend restrictions, which would otherwise be applicable pursuant to existing agreements between House of Doge and its stockholders, on the holders’ ability to transfer the shares of the Company’s common stock that are issued to HOD stockholders in the Merger; and (ii) impose similar transfer restrictions on holders of vested House of Doge restricted stock units that receive shares of the Company’s common stock in the Merger and limit the amount of shares that any such former holder of restricted stock units can transfer or otherwise dispose of based on the trading volume of the Company’s common stock on the Nasdaq Stock Market LLC or other applicable exchange on which shares of the Company’s common stock is then trading on the day prior to such transfer. The Amendment also provides that the Company will instruct the exchange agent to place appropriate stop transfer orders against or restrictive legends on the shares of the Company’s common stock issued to the former House of Doge stockholders or holders of restricted stock units in the Merger.

The amendment also extends the date after which either the Company or House of Doge can terminate the Merger Agreement if the transactions contemplated thereby have not been consummated to May 29, 2026.

The foregoing summary of the terms of the Amendment is subject to, and qualified in its entirety by, the full text of the Amendment, which is filed as Exhibit 2.1 to this Current Report on Form 8-K.
