Signing Day Sports announced the closing of its underwritten public offering, raising approximately $5.6 million in gross proceeds before fees and expenses. The company issued 9,483,500 shares of common stock together with warrants to purchase up to 14,225,250 additional shares. Each warrant is initially exercisable at a price of $0.7086 per share, may be converted on a zero-cash basis subject to a floor price of $0.6760 and a beneficial ownership limitation, and expires upon full exercise, five years from initial exercise, or completion of the business combination with BlockchAIn Digital Infrastructure, Inc. Maxim Group LLC served as sole book‐running manager. The registration statement on Form S-1 (File No. 333-292569) was declared effective by the SEC on January 13, 2026, with the final prospectus available electronically via the SEC’s website and directly from Maxim Group’s syndicate department.

Expanding beyond its established football offering, Signing Day Sports hosted its first college basketball combine in Salt Lake City, Utah, in collaboration with former NBA All-Star Thurl Bailey. Leveraging Bailey’s experience and youth-development expertise, the event validated the company’s video-verified measurables and data-driven recruitment tools—such as height, wingspan, shooting mechanics and academic credentials—in a basketball context. Management plans to roll out additional regional combines and integrate basketball-specific metrics into its app over the coming months, aiming to provide coaches nationwide with standardized, verified profiles for high school prospects and extend the company’s mission to empower student-athletes across multiple sports.
