Signing Day Sports (SGN) has set the exchange ratio for its three-way merger with BlockchAIn Digital Infrastructure and One Blockchain LLC, moving the deal one step closer to completion.
The merger structure will see SGN become a wholly owned subsidiary of BlockchAIn. At the same time, One Blockchain LLC will also merge into BlockchAIn through a separate subsidiary.
SGN stockholders will receive registered common shares of BlockchAIn as part of the deal. The exchange ratio is calculated by dividing SGN’s last reported sale price on the final trading day before closing by 7.5.
If that calculation produces a fractional share, it gets rounded up to one full share for that holder. It’s a small but practical detail that protects smaller investors from being left with nothing.
The agreement guarantees that SGN stockholders will hold at least 8.5% of BlockchAIn’s outstanding common shares on a fully diluted basis after the deal closes. That figure excludes any out-of-the-money options and warrants.
The exchange ratio adjustment is also designed to help BlockchAIn meet NYSE American listing requirements. Getting that listing is clearly a key goal for the combined company.
The SEC declared the Form S-4 registration statement effective, clearing a major regulatory hurdle. Proxy materials have already been sent to SGN stockholders seeking approval for the combination.

A second amendment extended the termination deadline from December 31, 2025, to February 17, 2026. If the S-4 was declared effective by that date, the termination window would extend further to April 30, 2026.
