Cadeler initiates its redomiciliation from
Denmark to the United Kingdom, to be implemented through a share exchange offer by Cadeler plc for all outstanding shares of Cadeler A/S
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.

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. As the Offer is being made in agreement
with the Cadeler Board, the Norwegian Financial Supervisory Authority has, pursuant to Section 6-16(4) of the Norwegian Securities Trading
Act, decided that the formal statement otherwise to be issued by the Cadeler Board under Section 6-16 shall instead be issued by Kroll,
LLC as an independent third party. 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). The statement by Kroll, LLC is publicly available on https://newsweb.oslobors.no/

duty or stamp duty reserve tax in the U.K., (xxix) the risk that the listing of shares in Cadeler plc on the New York Stock Exchange
and Oslo Stock Exchange may not succeed as expected, and (xxx) the ability of certain of the Cadeler Group’s largest shareholders
to influence matters requiring shareholder approval. The foregoing list of factors is not exhaustive and the factors identified are not
set out in any particular order. There can be no assurance that future developments affecting Cadeler plc, Cadeler or the Group will
be those that the Group has anticipated.
These forward-looking statements involve a number
of risks, uncertainties (some of which are beyond Cadeler plc's or Cadeler’s control) or other assumptions that may cause actual
results or performance to be materially different from those expressed or implied by these forward-looking statements or from historical
