This Amendment No. 1 to Schedule 13D hereby (this "Amendment") amends the Schedule 13D filed with the Securities and Exchange Commission on October 19, 2026 (the "Original Schedule 13D") by Phillip Oldridge (the "Reporting Person") with respect to the Class A ordinary shares, par value $0.0025 per share (the "Shares"), of Rantizo, a Cayman Islands exempted company limited by shares (the "Issuer") and having its principal executive offices at 211 Highland Cross Drive, Houston, TX 77073.

Capitalized terms used but not otherwise defined in this Amendment have the meanings given to them in the Original Schedule 13D. Except as expressly amended and supplemented by this Amendment, the Original Schedule 13D remains in full force and effect.
