Southport Acquisition Corp. II has reported the forfeiture of 666,667 Class B ordinary shares, a move that comes after underwriters chose not to exercise their remaining over-allotment option. This development is significant as it reflects adjustments following the company's recent initial public offering (IPO) on October 2, 2026, which generated gross proceeds of $210 million.

The forfeited shares were part of the 7,666,667 Class B ordinary shares held by Southport Acquisition Sponsor II LLC, the company's sponsor. Originally, up to 1,000,000 of these shares were subject to forfeiture based on the underwriters' actions. On October 19, 2026, the underwriters notified the company of their decision, leading to the cancellation of the forfeited shares.

The company trades under the ticker symbols PORT and PORT-UN on the New York Stock Exchange. It is classified under the Standard Industrial Classification (SIC) code 6770, which pertains to blank checks.
