Signing Day Sports completed a registered offering of 9,483,500 common shares together with detachable warrants to purchase 14,225,250 common shares, raising approximately $5.6 million in gross proceeds. Maxim Group LLC served as sole book-running manager, and the offering was declared effective under SEC File No. 333-292569 on January 13, 2026.

Each warrant grants the holder the right to acquire one share of common stock under terms that include an initial exercise framework and a formula-based cashless exercise option subject to a floor price of $0.6760 per share. Warrants may be exercised until January 23, 2026, and will expire upon full exercise, five years from issuance, or completion of the pending business combination with BlockchAIn Digital Infrastructure.

Proceeds from the offering are intended to support Signing Day Sports’ anticipated merger with BlockchAIn Digital Infrastructure, under an agreement first announced May 27, 2025. The combined entity aims to leverage the Company’s athlete recruitment platform alongside blockchain-enabled services, positioning the business for accelerated growth in digital sports infrastructure.

A final prospectus was filed on the SEC website and is available for review electronically via Maxim Group’s syndicate department. The offering was conducted solely by prospectus; no state-level sales occurred prior to qualification. Ongoing disclosures, including risk factors and forward-looking statements, remain accessible through the Company’s SEC filings.
