SUPPLEMENT TO PROXY STATEMENT
FOR 2026 ANNUAL GENERAL MEETING OF SHAREHOLDERS
To be held at 9:00 a.m., Eastern Time, on Thursday, June 11, 2026

This proxy statement supplement, dated May 6, 2026 (this “Supplement”), supplements the definitive proxy statement on Schedule 14A of Norwegian Cruise Line Holdings Ltd. (the “Company”), dated April 30, 2026 (the “Proxy Statement”), for the Company’s Annual Meeting of Shareholders to be held on June 11, 2026 (the “Annual Meeting”). The Company is providing this Supplement solely to revise the proxy card attached to the Proxy Statement to expand the description of Proposal 6 on the proxy card. Specifically, with respect to Proposal 6, the description of the shareholder proposal to be voted on at the Annual Meeting, if properly presented, has been revised to clarify that it relates to a proposal for declassification of the Board of Directors (the “Board”) of the Company.

Internet and telephone voting instructions are being updated to expand the description of Proposal 6. Instructions on how to vote or how to change or revoke a previously submitted proxy or voting instructions for the Annual Meeting are included in the “About the Annual General Meeting and Voting” section on page 86 of the Proxy Statement.

Your vote is important to us, and we appreciate your attention to this matter. Whether or not you plan to attend the Annual Meeting, we hope you will vote as soon as possible using the revised proxy card.

THIS SUPPLEMENT SHOULD BE READ IN CONJUNCTION WITH THE PROXY STATEMENT. EXCEPT AS SPECIFICALLY SUPPLEMENTED BY THE INFORMATION CONTAINED HEREIN, THIS SUPPLEMENT DOES NOT MODIFY ANY OF THE PROPOSALS OR OTHER INFORMATION SET FORTH IN THE PROXY STATEMENT, AND THE BOARD’S RECOMMENDATIONS ON THE PROPOSALS REMAIN UNCHANGED.
