Item 4. Description of Securities.

Item 5. Interests of Named Experts and Counsel.

Item 6. Indemnification of Directors and Officers.

Carnival Corporation’s Third Amended and Restated Articles of Incorporation and By-Laws provide, subject to the requirements set forth therein, that with respect to any person who was or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, Carnival Corporation shall indemnify such person by reason of the fact that he is or was one of Carnival Corporation’s or Carnival plc’s directors or officers, and may indemnify such person by reason of the fact that he is or was one of Carnival Corporation’s or Carnival plc’s employees or agents or is or was serving at Carnival Corporation’s or Carnival plc’s request as a director, officer, employee or agent in another corporation, partnership, joint venture, trust or other enterprise, in either case against expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted

2

in good faith and in a manner he reasonably believed to be in or not opposed to Carnival Corporation’s or Carnival plc’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Carnival Corporation has entered into agreements with each of its directors providing essentially the same indemnities as are described in Carnival Corporation’s Third Amended and Restated Articles of Incorporation in the event that such director or such director’s heirs, executors or administrators are made a party to threatened, pending or completed actions, suits or proceedings as described above.

Article 288 of Carnival plc’s Articles of Association provides:

“Subject to and in so far as permitted by the Companies Acts. the Company may: (a) indemnify any director, office or employee of the Company or of any associated company against any liability pursuant to any qualifying third party indemnity provision or any qualifying pension scheme indemnity provision, or on any other basis as is then lawful, in each case on such terms as the board may decide; and (b) purchase and maintain for any director, officer or employee of the Company or of any associated company insurance against any liability. In this article “qualifying third party indemnity provision”, “qualifying pension scheme provision” and “associated company” have meanings that they have in Part 10 of the 2006 Act.”

Under the UK Companies Act 2006, a UK company is not permitted to indemnify a director or officer of the company (or any person employed by the company as an auditor) against any liability in respect of any fine imposed in criminal proceedings, a sum payable to a regulatory authority by way of a penalty in respect of non-compliance with any requirement of a regulatory nature, negligence, default, breach of duty or breach of trust of which he may be guilty in relation to the company.

UK companies, however, may:

Carnival plc has entered into agreements with each of its directors providing essentially the same indemnities as are described in Carnival plc’s articles of association as described above.

Item 9. Undertakings

The undersigned registrant hereby undertakes:

(a)    (1)      To file during any period in which offers or sales are being made, a post-effective amendment to this 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 Securities Exchange Act of 1934 (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.

6

(b)    The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’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 the registrant pursuant to the foregoing provisions, or otherwise, the registrant 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 the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant 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, the registrant 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.

REGISTRATION STATEMENT ON FORM S-8 OF CARNIVAL CORPORATION AND CARNIVAL PLC

INTRODUCTION

1.     In connection with the joint registration statement on Form S-8 (the Registration Statement) of Carnival Corporation, a corporation organized under the laws of the Republic of Panama (Carnival Corporation) and Carnival Plc, a public limited company incorporated under the laws of England and Wales (the Company), under the Securities Act 1933 (the Act), we have been requested to render our opinion on certain matters in connection with the Registration Statement.

Freshfields Bruckhaus Deringer LLP is a limited liability partnership registered in England and Wales with registered number OC334789. It is authorised and regulated by the Solicitors Regulation Authority. For regulatory information please refer to www.freshfields.com/support/legalnotice.

A list of the members (and of the non-members who are designated as partners) of Freshfields Bruckhaus Deringer LLP is available for inspection at its registered office, 65 Fleet Street, London EC4Y 1HS. Any reference to a partner means a member, or a consultant or employee with equivalent standing and qualifications, of Freshfields Bruckhaus Deringer LLP or any of its affiliated firms or entities.

2.    The Registration Statement relates to the registration under the Act of the issuance of 10,000,000 shares of Carnival Corporation common stock issuable under the Carnival Corporation 2020 Stock Plan (the Plan), 10,000,000 trust shares (the Trust Shares) of beneficial interest in the P&O Princess Special Voting Trust, a trust established under the laws of the Cayman Islands, that are paired with the shares of Carnival Corporation common stock issuable under the Plan, which Trust Shares are paired with the shares of Carnival Corporation common stock on a one-for-one basis and represent a beneficial interest in a special voting share of the Company and the Company’s special voting share of 1 pound sterling in the capital of the Company (the Special Voting Share) issued to Carnival Corporation (such share having been transferred to the trustee of the P&O Princess Special Voting Trust).

3.    We are acting as English legal advisers to the Company for the purposes of giving this opinion. In so acting, we have examined the following documents:

The documents listed in paragraphs 3(a) to 3(f) above are referred to in this opinion as the Documents and we have relied upon the statements as to factual matters contained in or made pursuant to each of Documents. In this opinion, the Winding-Up Enquiry means our search (carried out by us or by GlobalX on our behalf) on 25 June 2021 of the Central Registry of Winding up Petitions.

ASSUMPTIONS

4.    In considering the Documents and rendering this opinion we have with your consent and without any further enquiry assumed:

2|8

3|8

OPINION

5.    Based on and relying solely upon the foregoing and the assumptions in paragraph 4 above and subject to the matters set out in paragraphs 6 and 7 below and excluding any matters not disclosed to us, we are of the opinion that the Special Voting Share has been duly authorised and validly issued and is fully paid and non-assessable.

For the purposes of this opinion, we have assumed that the term “non-assessable” in relation to the Special Voting Share means under English law that the holder of such share, in respect of which all amounts due on such share as to the nominal amount and any premium thereon have been fully paid, will be under no further obligation to contribute to the liabilities of the Company solely in its capacity as holder of such share.

QUALIFICATIONS

6.    Our opinion is subject to the following qualifications:

4|8

since notice of these matters may not be filed with the Registrar of Companies immediately and, when filed, may not be entered on the public microfiche of the relevant company immediately.

In addition, the Company Search is not capable of revealing, prior to the making of the relevant order or the appointment of an administrator otherwise taking effect, whether or not a winding-up petition or an application for an administration order has been presented or notice of intention to appoint an administrator under paragraphs 14 or 22 of Schedule B1 to the Insolvency Act 1986 (the Insolvency Act) has been filed with the court;

5|8

OBSERVATIONS

7.    We should also like to make the following observations, it should be understood that:

LIMITATIONS OF LIABILITY

8.    Where you have received advice from a number of advisers in connection with the matters on which we opine in this opinion or any related matter in respect of which we could be potentially jointly or severally liable with any such other advisers for losses suffered by

6|8

you, our liability will not be affected by any limitation of liability which you may agree with any other advisers. Accordingly, our liability to you will be limited to such proportion of the losses suffered by you as is finally determined to be just and equitable, having regard to the relative responsibility of ourselves and any other person who is jointly or severally liable for such losses. If you have received advice from any other advisers with respect to matters on which we opine in this opinion which qualifies such opinions then, to the extent that such advice is correct, you will not place any reliance on the unqualified opinions contained in this opinion, and we will have no liability to you in connection therewith.

9.    Your reliance on the matters addressed in this opinion letter is on the basis that any associated recourse is against the firm’s assets only and not against the personal assets of any individual partner. The firm’s assets for this purpose consist of all assets of the firm’s business, including any right of indemnity of the firm or its partners under the firm’s professional indemnity insurance policies, but excluding any right to seek contribution or indemnity from or against any partner of the firm or person working for the firm or similar right. The restrictions in the previous sentences apply to any claim, whether in contract, tort (including negligence) for breach of statutory duty, or otherwise, but they do not apply in the case of our willful misconduct or fraud or where and to the extent prohibited by applicable law and regulation (including without limitation, the rules of professional responsibility governing the practice of law).

10.    This opinion is confined to matters of English law (including case law) as applied as at the date of this opinion by the English courts and is given on the basis that it and any non-contractual obligations arising out of or in relation to this opinion will be governed by and construed in accordance with current English law. Accordingly, we express no opinion with regard to any system of law other than the laws of England as currently applied by the English courts.

11.    We hereby consent to the use of our name in the Registration Statement and to the filing of this opinion as Exhibit 5.3 to the Registration Statement. In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required by the Act or by the rules and regulations promulgated thereunder.

BENEFIT OF OPINION

12.    This opinion is given to you for your benefit in relation to the Registration Statement to be filed under the Act. It is not to be transmitted to any person nor is it to be relied upon by any other person or for any purposes or quoted or referred to in any public document without our prior written consent, except that we consent to the use of our name in the Registration Statement on the basis stated in paragraph 11.

GOVERNING LAW AND JURISDICTION

13.    This opinion and any non-contractual obligations arising out of or in relation to this opinion are governed by English law.

14.    The English courts shall have exclusive jurisdiction, to which you and we submit, in relation to all disputes (including claims for set-off and counterclaims) arising out of or in

7|8

connection with this opinion, including, without limitation, disputes arising out of or in connection with: (i) the creation, effect or interpretation of, or the legal relationships established by, this opinion; and (ii) any non-contractual obligations arising out of or in connection with this opinion.
