EXPLANATORY NOTE

Signing Day Sports, Inc., a Delaware corporation (the "Company" or "Signing Day Sports"), is filing this Amendment No. 2 on Form 8-K/A to amend its Current Report on Form 8-K, filed with the U.S. Securities and Exchange Commission (the "SEC") on July 22, 2025 (the "Original Form 8-K"), as amended by its Amendment No. 1 on Form 8-K/A filed with the SEC on August 29, 2025 (the "Form 8-K/A1"), to amend Item 8.01 and Item 9.01 to the Form 8-K/A1. Other than as disclosed in such amended items, this filing does not update, amend, or modify any information, statement or disclosure contained in or filed with the Original Form 8-K or Form 8-K/A1.

Item 8.01 Other Events.

As previously reported in the Current Report on Form 8-K filed by Signing Day Sports with the SEC on May 28, 2025 (the "Prior Form 8-K"), on May 27, 2025, the Company entered into a Business Combination Agreement (the "Business Combination Agreement") with BlockchAIn Digital Infrastructure, Inc., a Delaware corporation ("BlockchAIn" or the "Combined Company"), One Blockchain LLC, a Delaware limited liability company ("One Blockchain"), BCDI Merger Sub I Inc., a Delaware corporation and a wholly owned subsidiary of BlockchAIn ("Merger Sub I"), and BCDI Merger Sub II LLC, a Delaware limited liability company and a wholly owned subsidiary of BlockchAIn ("Merger Sub II").

The Business Combination Agreement provides that, upon the terms and subject to the conditions set forth therein, the parties will effect a business combination transaction in which: (a) Merger Sub I will merge with and into Signing Day Sports (the "First Merger"), with Signing Day Sports surviving the First Merger as a direct wholly owned subsidiary of BlockchAIn; and (b) Merger Sub II will merge with and into One Blockchain (the "Second Merger" and, together with the First Merger, the "Business Combination," and, together with the other transactions contemplated by the Business Combination Agreement, the "Transactions"), with One Blockchain surviving the Second Merger as a direct wholly owned subsidiary of BlockchAIn. At the effective time of the First Merger, each outstanding share of common stock of Signing Day Sports, $0.0001 par value per share ("Signing Day Sports common stock"), will be automatically canceled and converted into the right to receive a common share, $0.0001 par value per share, of BlockchAIn (collectively, "BlockchAIn common shares" or "BlockchAIn common stock"). Each outstanding Signing Day Sports option and warrant will be assumed by BlockchAIn and converted into options and warrants, respectively, to acquire BlockchAIn common shares, with the same terms and conditions, including exercise price, and each assumed option will immediately become fully vested. At the effective time of the Second Merger, the outstanding membership interests of One Blockchain (collectively, "One Blockchain membership interests") will be canceled and converted into the right to receive a number of BlockchAIn common shares equal to the quotient of the total number of shares of Signing Day Sports common stock outstanding immediately prior to the First Merger on a fully diluted and as-converted basis, not including certain out-of-the-money derivative securities, divided by 0.085, less the total number of BlockchAIn common shares that the shares of Signing Day Sports common stock will be converted into the right to receive at the effective time of the First Merger, subject to certain adjustments.

The Business Combination Agreement provides for the issuance of additional BlockchAIn common shares (the "Earnout Shares") to Tiger Cloud LLC, a Delaware limited liability company ("Tiger Cloud"), and VCV Digital Solutions LLC, a Delaware limited liability company ("VCV Digital" and together with Tiger Cloud, the "One Blockchain Securityholders"), who hold One Blockchain membership interests immediately prior to the closing of the Business Combination (the "Closing") (which is expected to occur in the fourth quarter of 2025) if the net income plus interest, taxes, depreciation and amortization of BlockchAIn for the fiscal year ending December 31, 2026 ("2026 EBITDA") equals or exceeds $25 million. The Earnout Shares will equal 11.628% of the total number of BlockchAIn common shares issued to the One Blockchain Securityholders at the Closing, subject to adjustment. If the conditions for the issuance of the Earnout Shares are met, the Earnout Shares will be issued within ten calendar days following the date on which BlockchAIn files its annual report for its 2026 fiscal year with the SEC.

In addition, the Business Combination Agreement provides that BlockchAIn will issue to Maxim Partners LLC ("Maxim Partners") (or its designees) a number of BlockchAIn common shares equal to 3.5% of the total transaction enterprise value at the Closing, and, if applicable, 3.5% of the Earnout Shares, in accordance with the M&A Advisory Agreement between One Blockchain c/o VCV Digital and Maxim Group LLC ("Maxim Group"), dated January 29, 2025 (the "Advisory Agreement"). The number of BlockchAIn common shares issued to Maxim Partners (or its designees) will reduce only the equity ownership otherwise allocable to the holders of One Blockchain membership interests.

The Business Combination Agreement provides that BlockchAIn may adjust the number of BlockchAIn common shares into which the shares of Signing Day Sports common stock and the One Blockchain membership interests may be converted so long as the aggregate number of BlockchAIn common shares that the Signing Day Sports stockholders (the "Signing Day Sports Stockholders") are entitled to receive pursuant to the terms of the Business Combination Agreement will be at least 8.5% of the BlockchAIn common shares that are outstanding on a fully diluted basis immediately after the Closing (excluding any out-of-the-money options and warrants) and (ii) such adjustment does not have a negative impact on the qualification of the BlockchAIn common shares to become listed on the NYSE American LLC (the "NYSE American").

For a description of certain additional terms and conditions that are contained in the Business Combination Agreement, see the Prior Form 8-K, which is incorporated by reference herein.
