(“BlockchAIn”), a newly formed Delaware corporation created for the purpose of consummating the Company’s previously announced business combination with One Blockchain LLC (“One Blockchain”). The filing follows the Company’s confidential submissions of drafts of the Registration Statement with the SEC on July 8, 2025, August 28, 2025, and September 24, 2025.

As previously disclosed, on May 27, 2025, Signing Day Sports entered into a Business Combination Agreement with BlockchAIn, One Blockchain, and certain other parties, as amended on November 10, 2025. The Registration Statement provides information on the proposed business combination and listing of BlockchAIn common shares on the NYSE American LLC (“NYSE American”) under the ticker symbol “AIB.”

“Today marks an important milestone in our progress toward completing the business combination with One Blockchain and launching BlockchAIn as a publicly traded company,” said Daniel Nelson, Chief Executive Officer and Chairman of Signing Day Sports. “Filing the Registration Statement reflects the coordinated effort, preparation, and discipline shown by both organizations throughout this process. From the beginning, it has been clear that this combination is a strategic alignment of vision and long-term objectives. Our teams have worked together with a shared sense of purpose, ensuring that each step has been executed thoroughly and on schedule.”

“Looking ahead, we believe the combined company will be well-positioned to leverage Signing Day Sports’ technology-driven recruitment platform alongside One Blockchain’s digital infrastructure and high-performance computing resources. This structure will provide greater financial flexibility and broader technical capabilities. It also gives us the ability to pursue scalable growth initiatives that were previously out of reach.”

“The transaction further enables us to accelerate innovation across our platform and enhance the tools we offer to student-athletes and coaches. It creates opportunities to expand into new markets and partnerships. With our anticipated improved operational capacity and access to the public markets, we are confident in our ability to advance key initiatives, strengthen our competitive position, and create long-term value for shareholders.”

“I am incredibly proud of the diligence and collaboration that have brought us to this point, and we remain focused on completing this transformative transaction and executing on the opportunities that lie ahead,” concluded Nelson.
