26. March 2026 kl. 12:55

NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART, DIRECTLY OR INDIRECTLY, IN OR INTO THE UNITED STATES, AUSTRALIA, CANADA, HONG KONG, SOUTH AFRICA OR JAPAN, EXCEPT AS PERMITTED BY APPLICABLE LAW, OR ANY OTHER JURISDICTION IN WHICH THE RELEASE, PUBLICATION OR DISTRIBUTION IS UNLAWFUL OR REQUIRES REGISTRATION OR ANY OTHER MEASURES.

THIS ANNOUNCEMENT IS NOT A PROSPECTUS AND DOES NOT CONSTITUTE A PUBLIC OFFER OF ANY OF THE SECURITIES DESCRIBED HEREIN.

Reference is made to the stock exchange announcement made by Cadeler A/S (“Cadeler” or the “Company”) on 25 March 2026, regarding a contemplated private placement of new ordinary shares in the Company, each with a par value of DKK 1.00 (the “Offer Shares”), up to 10% of the outstanding share capital in the Company (the “Private Placement”).

The Company is pleased to announce that the Private Placement has been successfully completed, raising gross proceeds of approximately NOK 1,965 million (equivalent to approximately USD 203 million) through the allocation of 35,095,758 Offer Shares, each at an offer price of NOK 56.00, equivalent to approximately 10% of the Company’s outstanding shares. The Private Placement took place through an accelerated bookbuilding process managed by DNB Carnegie, a part of DNB Bank ASA, and Jefferies GmbH (jointly, the “Managers”) as Joint Global Coordinators and Joint Bookrunners.

The Company intends to use the net proceeds from the Private Placement, alongside available cash-on-hand and operational cash flow, to finance the equity portion of i) two proposed Wind Foundation Installation Vessel newbuilds (the “T-Class newbuilds”), to be delivered in mid-2030 and mid-2031, and ii) the potential acquisition and conversion of a heavy-lift vessel to a +23,000t inclined fall-pipe vessel, which, if acquired, would enable the Company to internalize the scour protection (rock installation) scope.

It is emphasised that no agreements have been entered into with respect to the possible T-Class newbuilds or with respect to the possible heavy-lift vessel contemplated for conversion into an inclined fall-pipe vessel for scour protection, that it may be that no such agreements will be exercised, and that terms described herein are indicative and current estimates only and may change (if and when agreements are entered into).

BW Altor Pte. Ltd. (“BW Altor”) and Scorpio Holdings Limited (“Scorpio”) were allocated 12,126,875 and 6,929,642 Offer Shares, corresponding to the NOK equivalent of approximately USD 70m and 40m in the Private Placement. Following completion of the Private Placement and the issuance of the New Shares (as defined below), BW Altor and Scorpio will hold 108,292,909 and 49,356,825 shares, respectively, in the Company, representing approximately 28.1% and 12.8%, respectively, of the outstanding shares in the Company.

The Private Placement, allocation of the Offer Shares and issuance of new shares corresponding to the final number of Offer Shares (the "New Shares") at NOK 56.00 per share were resolved by the board of directors of the Company (the “Board”) following advice from the Managers after the book-building process in accordance with Article 3.1 in Cadeler’s Articles of Association, pursuant to which the Board is authorised to make the share capital increase under the authorisation granted to the Board by the general meeting on 23 April 2024.

Delivery of the Offer Shares allocated to investors (other than BW Altor) in the Private Placement will be made by delivery of existing shares in the Company already listed on Euronext Oslo Børs pursuant to a share lending agreement (the "Share Lending Agreement") entered into by the Company, DNB Carnegie, a part of DNB Bank ASA (on behalf of the Managers) and BW Altor for the purpose of facilitating delivery-versus-payment (“DVP”) settlement. The Offer Shares allocated to applicants (other than BW Altor) will thus be tradable from allocation. The Managers will settle the share loan and deliver Offer Shares to BW Altor with the New Shares to be issued by the Company upon receiving full payment and registration of the New Shares with the Danish Business Authority.

Notification of allocation, including settlement instructions, is expected to be distributed by the Managers today, 26 March 2026 at 13:00 (CET), with settlement on a DVP basis on or about 30 March 2026.

The Private Placement involves the setting aside of the shareholders’ preferential rights to subscribe for shares in the Company. When resolving the issuance of the New Shares in the Private Placement, the Board considered the equal treatment obligations under the Norwegian Securities Trading Act and applicable Danish law. The Board is of the opinion that the Private Placement is in compliance with the equal treatment requirements and that it is in the common interest of the Company and its shareholders to raise equity through a private placement. By structuring the transaction as a private placement, the Company was able to raise capital in an efficient manner with significantly lower completion risks compared to a rights issue with longer lead time and higher cost, and strengthen the Company's shareholder base. The Private Placement was publicly announced prior to commencement of the bookbuilding process and the offer price of NOK 56.00 per share was based on the applications in the accelerated bookbuilding process. The price is therefore considered to represent professional investors' view of the market price for the shares in a share offering of this size. Based on this, the Board resolved not to conduct a subsequent offering directed towards shareholders not participating in the Private Placement.

The New Shares

The New Shares will rank pari passu in all respects with existing shares in Cadeler. The New Shares will be negotiable instruments, and no restrictions will apply to their transferability. No shares, including the New Shares, carry or will carry any special rights. Rights conferred by the New Shares, including voting rights and dividend rights, will apply from the time when the capital increase is registered with the Danish Business Authority. The New Shares must be registered in the name of the holder in the Company’s register of shareholders.

The nominal par value of the share capital increase of DKK 35,095,758.00 pertaining to the Private Placement represents 10.0% of Cadeler’s currently registered share capital, and will account for 9.1% of Cadeler’s registered share capital upon completion of the share capital increase, which will constitute a nominal par value of DKK 386,053,341.00 divided into 386,053,341shares of a nominal par value of DKK 1.00 each.
