each of CCIX’s current executive officers and directors, and all executive officers and directors of CCIX as a group, in each case pre-business combination;

each person who will become a named executive officer or director of the Post-Closing Company, and all executive officers and directors of the Post-Closing Company as a group, in each case post-business combination;

each person who is known to be the beneficial owner of more than five percent of (1) PlusAI Class A common stock or (2) PlusAI Class B common stock; and

each person who is expected to be the beneficial owner of more than five percent of either the Post-Closing Company Class A common stock or Post-Closing Company Class A common stock post-business combination.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if they possess sole or shared voting or investment power over that security. Unless otherwise indicated, CCIX believes that all persons named in the table below have sole voting and investment power with respect to the voting securities beneficially owned by them.

Shares subject to stock options or warrants that are currently exercisable or exercisable within 60 days of September 30, 2025 and RSUs that would vest based on time and service-based vesting conditions, assuming any applicable liquidity event condition had been achieved, within 60 days of September 30, 2025 are deemed to be outstanding and to be beneficially owned by the person holding the stock option, warrant or RSU for the purpose of computing the percentage ownership of that person. These shares have not been deemed outstanding, however, for the purpose of computing the percentage ownership of any other person, and have not been deemed to be outstanding or beneficially owned for the purpose of the calculation of percentage of votes in the table below.

The beneficial ownership of CCIX Ordinary Shares pre-business combination is based on 29,475,000 CCIX Class A Ordinary Shares and 7
