EXPLANATORY NOTE

On May 7, 2026, Carnival Corporation & plc completed the unification of its dual-listed company structure under a single company, Carnival Corporation Ltd., with Carnival plc as the wholly-owned UK subsidiary of Carnival Corporation (the "DLC Unification"). As part of the DLC Unification, Carnival Corporation migrated its jurisdiction of incorporation from Panama to Bermuda and changed its name to Carnival Corporation Ltd. (the "Redomiciliation"), and Carnival plc will subsequently be re-registered as a private limited company.

These Post-Effective Amendments (the "Post-Effective Amendments") are being filed to (i) withdraw and remove from registration certain securities of Carnival plc that remain unsold or otherwise unissued and (ii) to amend the terms of previously registered shares of Carnival Corporation common stock to describe the common shares, par value $0.01 per share (the "Common Shares"), of Carnival Corporation Ltd. following the Redomiciliation. As a result of the Redomiciliation, the rights of holders of Common Shares are now governed by the Memorandum of Continuance and Bye-Laws of Carnival Corporation Ltd., which are filed as exhibits hereto. These Post-Effective Amendments do not reflect any increase in the number of shares issuable pursuant to any of the plans listed on the cover page hereof (each, a "Plan" and collectively, the "Plans"). For the avoidance of doubt, the registration of Common Shares under each Registration Statement remains in full force and effect.

DEREGISTRATION OF SECURITIES

Carnival plc is filing Post-Effective Amendments to the following Registration Statements on Form S-8 previously filed with the Commission to withdraw and remove from registration (i) the Carnival plc special voting share, £1.00 par value (the "Special Voting Share"), held by the P&O Princess Special Voting Trust, (ii) the trust shares of beneficial interest in the P&O Princess Special Voting Trust (the "Trust Shares") and (iii) ordinary shares, represented by American Depositary Shares (the "ADS Shares"), that remain unsold or otherwise unissued under each Registration Statement:

·

Registration Statement No. 333-288351-01 filed with the Commission on June 26, 2025, relating to the registration of the Special Voting Share and 4,000,000 Trust Shares authorized for issuance under the Carnival Corporation 1993 Employee Stock Purchase Plan, as amended.

·

Registration Statement No. 333-272977-01 filed with the Commission on June 28, 2023, relating to the registration of the Special Voting Share and 21,650,000 Trust Shares authorized for issuance under the Carnival Corporation 2020 Stock Plan.

·

Registration Statement No. 333-257471-01 filed with the Commission on June 28, 2021, relating to the registration of the Special Voting Share and 10,000,000 Trust Shares authorized for issuance under the Carnival Corporation 2020 Stock Plan.

·

Registration Statement No. 333-237616-01 filed with the Commission on April 9, 2020, relating to the registration of the Special Voting Share and 15,000,000 Trust Shares authorized for issuance under the Carnival Corporation 2020 Stock Plan.

·

Registration Statement No. 333-173465-01 filed with the Commission on April 13, 2011, relating to the registration of the Special Voting Share and 15,000,000 Trust Shares authorized for issuance under the Carnival Corporation 2011 Stock Plan.

·

Registration Statement No. 333-125418-01 filed with the Commission on June 1, 2005, relating to the registration of the Special Voting Share and 200,000 Trust Shares authorized for issuance under the Amended and Restated Carnival Corporation 2001 Outside Director Stock Plan.

·

Registration Statement No. 333-124640 filed with the Commission on May 4, 2005, relating to the registration of 2,000,000 ADS Shares authorized for issuance under the Carnival plc 2005 Employee Stock Purchase Plan.

·

Registration Statement No. 333-104609 filed with the Commission on April 17, 2003, relating to the registration of the Special Voting Share and 55,143,012 Trust Shares.

For the avoidance of doubt, the Post-Effective Amendments to the above Registration Statements do not terminate the registration of Common Shares of Carnival Corporation Ltd. under any of the foregoing Registration Statements, which registration remains in full force and effect.

As a result of the consummation of the DLC Unification, Carnival plc has terminated all offerings of its securities pursuant to each Registration Statement. In accordance with an undertaking made by Carnival plc in each Registration Statement to remove from registration, by means of a post-effective amendment, any securities which remain unsold or unissued at the termination of the offering, Carnival plc hereby removes and withdraws from registration all securities of Carnival plc registered pursuant to any Registration Statement that remain unsold or otherwise unissued as of the date hereof. Each Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such securities, and Carnival plc hereby terminates the effectiveness of such Registration Statement.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Section 98 of the Companies Act 1981 of Bermuda, as amended (the "Bermuda Companies Act") provides generally that a Bermuda company may indemnify its directors, officers and auditors against any liability which by virtue of any rule of law would otherwise be imposed on them in respect of any negligence, default, breach of duty or breach of trust, except in cases where such liability arises from fraud or dishonesty of which such director, officer or auditor may be guilty in relation to the company. Section 98 further provides that a Bermuda company may indemnify its directors, officers and auditors against any liability incurred by them in defending any proceedings, whether civil or criminal, in which judgment is awarded in their favor or in which they are acquitted or granted relief by the Supreme Court of Bermuda pursuant to Section 281 of the Bermuda Companies Act.

Carnival Corporation Ltd.'s Bye-Laws provide that Carnival Corporation Ltd. will indemnify the officers and directors with respect to their actions and omissions, except in respect of their fraud or dishonesty but otherwise to the fullest extent and in the manner set forth in and permitted by the Bermuda Companies Act and any other applicable law from time to time in effect. Carnival Corporation Ltd.'s Bye-Laws provide that the shareholders waive all claims or rights of action that they might have, individually or in right of the company, against any of the company's directors or officers for any act or failure to act in the performance of such director's or officer's duties, except in respect of any fraud or dishonesty of such director or officer. Section 98A of the Bermuda Companies Act permits Carnival Corporation Ltd. to purchase and maintain insurance for the benefit of any officer or director in respect of any loss or liability incurred by such person in such capacity or arising out of his status as such, whether or not Carnival Corporation Ltd. may otherwise indemnify such officer or director.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

Not applicable.

ITEM 8. EXHIBITS.

The Exhibits to this registration statement on Form S-8 are listed in the Exhibit Index attached hereto and incorporated herein by reference.

ITEM 9. UNDERTAKINGS.

(a)

Carnival Corporation Ltd. hereby undertakes:

(1)      To file during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by us pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement;

(2)           That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)           To remove from registration by means of a post-effective amendment any of the securities being registered hereby which remain unsold at the termination of the offering.

(b)           Carnival Corporation Ltd. hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of Carnival Corporation Ltd.'s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering hereof.

(c)           Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of Carnival Corporation Ltd. pursuant to the foregoing provisions, or otherwise, Carnival Corporation Ltd. has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Carnival Corporation Ltd. of expenses incurred or paid by a director, officer or controlling person of Carnival Corporation Ltd. in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, Carnival Corporation Ltd. will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
