AIIA starts separate NYSE trading for Class A shares and rights

Rhea-AI Filing Summary

AI Infrastructure Acquisition Corp. reported that, starting on November 24, 2025, investors who bought its IPO units can choose to trade the pieces of those units separately. Each unit had included one Class A ordinary share and one right to receive one-fifth of a Class A ordinary share if the company completes its first business combination.

The Class A ordinary shares now trade on the New York Stock Exchange under the symbol “AIIA”, and the rights trade under “AIIA R”. Any units that are not split will keep trading under “AIIA U”. Holders who want to separate their units must have their brokers contact the transfer agent, Odyssey Transfer and Trust Company. The company also issued a press release describing this change.
