 5. PFIC Considerations.”

Each U.S. Holder is urged to consult its own tax advisor concerning the application of the PFIC rules, including the proposed Treasury Regulations, to the exchange of CCIX Class A Ordinary Shares for CCIX Class A Common Stock and CCIX Warrants for CCIX Delaware Warrants pursuant to the Domestication.

Moreover, U.S. Holders of CCIX public shares exercising redemption rights will be subject to the potential tax consequences of the Domestication.

Additionally, the Domestication may cause Non-U.S. Holders (as defined in “Proposal No. 1 — The Business Combination Proposal — Material U.S. Federal Income Tax Consequences of the Business Combination to CCIX Shareholders”) to become subject to U.S. federal withholding taxes on any amounts treated as dividends paid in respect of such Non-U.S. Holder’s PlusAI common stock after the Domestication.

The tax consequences of the Domestication are complex and will depend on a holder’s particular circumstances. All holders of CCIX Class A Ordinary Shares or CCIX Warrants are urged to consult their tax advisor regarding the tax consequences to them of the Domestication, including the applicability and effect of U.S. federal, state, local and non-U.S. tax laws. The opinion of Willkie Farr & Gallagher LLP, a copy of which is attached as an exhibit to the registration statement of which this proxy statement/prospectus is a part, expresses no opinion on the potential U.S. federal income tax consequences of the Domestication pursuant to Section 367 of the Code or the PFIC rules. For a more complete discussion of the U.S. federal income tax considerations of the Domestication, see “Proposal No. 1 — The Business Combination Proposal — Material U.S. Federal Income Tax Consequences of the Business Combination to CCIX Shareholders.”
