THE OFFER IS MADE IN THE EU/EEA SOLELY BY MEANS OF THE PROSPECTUS (AS DEFINED BELOW), AND IN THE UNITED STATES, THE U.S. PROSPECTUS/OFFER TO EXCHANGE (AS DEFINED BELOW). COPIES OF THE PROSPECTUS OR THE U.S. PROSPECTUS/OFFER TO EXCHANGE, AS APPLICABLE, MAY BE OBTAINED THROUGH THE WEBSITE OF CADELER AS SET FORTH ELSEWHERE IN THIS ANNOUNCEMENT.

Copenhagen, 21 September 2026 – With reference to the stock exchange announcement made by Cadeler A/S (”Cadeler”, and together with its consolidated subsidiaries, the “Cadeler Group”) on 27 August 2026, regarding the public filing of Registration Statement on Form F-4 with the SEC (as defined below), Cadeler plc, a public limited company incorporated under the laws of England and Wales, has today published a combined EU/EEA prospectus and offer document (the “Prospectus”) in connection with a contemplated redomiciliation of the Cadeler Group’s parent company from Denmark to the United Kingdom (the ”Redomiciliation”).

In connection with the Redomiciliation, Cadeler plc is making a voluntary offer to all holders of shares in Cadeler, each with a nominal value of DKK 1.00 (the “Cadeler Shares”), including Cadeler Shares represented by American Depositary Shares (each representing four (4) Cadeler Shares) (“Cadeler ADSs”), to exchange each Cadeler Share for one (1) share in Cadeler plc (the “Offer”). Holders of Cadeler ADSs who participate in and whose Cadeler Shares are accepted in the Offer will accordingly receive four (4) shares in Cadeler plc in exchange for each Cadeler ADS.

In addition to the Prospectus, and as announced on 27 August 2026, Cadeler plc has filed with the U.S. Securities and Exchange Commission (the “SEC”) a Registration Statement on Form F-4 under the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”), which includes an offering prospectus/offer to exchange (the “U.S. Prospectus/Offer to Exchange”).

Following completion of the Offer, each Cadeler shareholder will hold the same number of Cadeler plc shares as the number of Cadeler Shares (including Cadeler Shares represented by Cadeler ADSs) validly tendered by such shareholder in the Offer. Assuming that all outstanding Cadeler Shares (including Cadeler Shares represented by Cadeler ADSs) are tendered and exchanged pursuant to the Offer, each Cadeler shareholder will hold the same ownership (as a percentage of the outstanding share capital) in the Cadeler Group after the Offer as they held immediately prior to completion of the Offer.

"The Redomiciliation marks an important next step in Cadeler’s evolution. By establishing a UK-incorporated parent company, we are positioning the Group to attract a broader and more diverse international investor base, while creating a corporate structure that better reflects the scale and global reach of our operations. The board of directors fully supports this transaction", says Andreas Sohmen-Pao, Chair of the Cadeler Board (as defined below).

"The launch of the Offer is a significant milestone for the Cadeler Group. The Redomiciliation will provide a more flexible platform from which we can pursue our growth ambitions, strengthen our presence in key markets including the United Kingdom, and allow us to build on the momentum we have built since our initial listing on the Oslo Stock Exchange in 2020 and the New York Stock Exchange in 2023. We look forward to the next chapter of our journey as Cadeler plc", says Mikkel Gleerup, CEO of Cadeler.

Reasons for the Redomiciliation

The purpose of the Redomiciliation is to enhance the Cadeler Group’s strategic position. While the business carried out by the Cadeler Group following the implementation of the Redomiciliation will remain the same, the board of directors of Cadeler (the “Cadeler Board”) and the board of directors of Cadeler plc believe that the Redomiciliation and the direct listing and trading of Cadeler plc shares on the Oslo Stock Exchange and on the New York Stock Exchange (“NYSE”) will improve the marketability of the Cadeler Group and encourage a broader and more diversified international investor base. Additionally, the Redomiciliation supports the Cadeler Group’s business strategy generally, including by facilitating the greater physical presence of its senior management team in the United Kingdom and elsewhere in the markets in which the Cadeler Group operates.

For further details on the reasons behind the Redomiciliation, reference is made to Section 17.1.3 “Background and reasons for the Redomiciliation” of the Prospectus.

Highlights of the Offer

• Exchange ratio. Cadeler shareholders are offered one (1) share in Cadeler plc for each Cadeler Share tendered, including Cadeler Shares represented by Cadeler ADSs (each representing four (4) Cadeler Shares).

Eligible Cadeler shareholders may accept the Offer in the period from and including 22 September 2026 to 21 October 2026 at 5:00 PM Eastern Time / 11:00 PM CEST (or such subsequent date to which the expiration of the Offer is extended) as set out in the Prospectus and U.S. Prospectus/Offer to Exchange.

• Listing and delisting. Following completion of the Offer, Cadeler plc shares are expected to be listed and admitted to trading on the Oslo Stock Exchange and the NYSE, and the Cadeler Shares (including Cadeler Shares represented by Cadeler ADSs) are expected to be delisted from Oslo Stock Exchange and NYSE, respectively. Cadeler’s American Depositary Receipt programme will be terminated. The Cadeler plc shares are expected to commence trading on both the Oslo Stock Exchange and NYSE on 29 October 2026.

In addition, the Offer is conditional upon, among other things, there being no legal prohibition, the Registration Statement on Form F-4 filed with the SEC having become effective, the Prospectus having been approved by the Norwegian Financial Supervisory Authority and passported to Denmark, and the Cadeler plc shares having been approved for listing on the NYSE and for admission to trading on the Oslo Stock Exchange. The full conditions to the Offer are set out in the Prospectus and in the U.S. Prospectus/Offer to Exchange, and it is expected that an announcement by Cadeler plc with preliminary results on whether or not the conditions to the Offer have been satisfied or, to the extent legally permitted, waived will be published on or prior to 22 October 2026, and that an announcement with the final results will be published on or prior to 26 October 2026.

Squeeze-out

If the Offer is completed and Cadeler plc holds more than 90% of the total number and of the aggregate voting power of the Cadeler Shares then outstanding (excluding any treasury shares held by Cadeler), then Cadeler plc intends, as promptly as practicable thereafter, to initiate and complete a compulsory acquisition of the Cadeler Shares (including Cadeler Shares represented by Cadeler ADSs) not acquired in the Offer, for cash, in accordance with the Danish Companies Act (the “Squeeze-out”).

To initiate the Squeeze-out, Cadeler plc will publish a notice requesting that remaining Cadeler shareholders transfer their Cadeler Shares, including Cadeler Shares represented by Cadeler ADSs (the “Squeeze-out Cadeler Shares”), to Cadeler plc within a four-week period to be set out in such notice. The cash consideration to be paid for the Squeeze-out Cadeler Shares will be determined by Cadeler plc in accordance with Danish law, and will be based on the price of the Cadeler Shares on the Oslo Stock Exchange prior to the initiation of the Offer. After the expiry of such four-week period, any Squeeze-out Cadeler Shares not committed to be transferred will be acquired compulsorily by Cadeler plc. Cadeler plc has entered into a financing arrangement with DNB Bank ASA for the purpose of financing any cash payments due in connection with the Squeeze-out.

Tax considerations

Cadeler shareholders and potential investors are advised to consult their own tax advisers regarding the applicable tax consequences of the Offer and the Squeeze-out, as well as acquiring, holding and disposing of the Cadeler Shares, based on their particular circumstances.

Recommendation by the board of directors and independent third-party statement

The Cadeler Board and the board of directors of Cadeler plc, respectively, have unanimously determined that the Redomiciliation, including the Offer, is fair to, and in the best interests of, the two companies and their shareholders. The Cadeler Board unanimously recommends that Cadeler shareholders accept the Offer and tender their Cadeler Shares (including Cadeler Shares represented by Cadeler ADSs) pursuant to the Offer.

The Cadeler Board has based its recommendation on an assessment of various factors including, but not limited to, the strategic benefits of the Redomiciliation involving a broader international investor base, greater financing flexibility, commercial advantages from expanded United Kingdom operations following the Eneti combination, improved risk management and more efficient internal cash flows. The Cadeler Board has also considered the terms of the Offer, including the one-for-one exchange ratio, and believes the Offer is fair to, and in the best interests of, Cadeler and its shareholders as a whole.

The members and the composition of the board of directors of Cadeler plc are identical to the Cadeler Board, including with respect to the chair and vice chair.

This statement by the Cadeler Board does not constitute a statement as described in Section 6-16 of the Norwegian Securities Trading Act.

In its statement, Kroll, LLC has concluded that as of the date hereof, the Offer Consideration (as defined in the Prospectus) is fair from a financial point of view to the Cadeler’s shareholders (without giving effect to any impact on any particular shareholder other than in its capacity as a shareholder).
