Capital markets analyst

Administrative step in the CEPT–Securitize de-SPAC; terms to come in S-4.

This notice signals progression toward a de-SPAC: CEPT and Securitize signed a Business Combination Agreement on October 27, 2025, and intend to file a Form S-4 containing the proxy/prospectus. It also references a concurrent PIPE of CEPT Class A ordinary shares and clarifies those PIPE securities are unregistered at this stage.

Key dependencies include CEPT shareholder approval, transaction closing conditions, potential redemptions, and Pubco’s exchange listing status. The filing lists sector-specific uncertainties tied to digital assets and tokenization, alongside typical public-company cost and execution factors.

Investors can later evaluate economics—such as consideration mix, redemption levels, and any PIPE terms—once the S-4 is available. Actual outcomes will hinge on approvals and market conditions described in the risk disclosures.
