Copenhagen, 29 October 2026 - Reference is made to the stock exchange
announcement dated 21 September 2026 made by Cadeler A/S ("Cadeler", and
together with its consolidated subsidiaries, the "Cadeler Group") regarding the
launch of the voluntary offer (the "Offer") by Cadeler plc 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, each with a nominal value of USD 1.00,
in connection with the contemplated redomiciliation of the Cadeler Group's
parent company from Denmark to the United Kingdom (the "Redomiciliation"), and
to the stock exchange announcement made by Cadeler earlier today regarding the
preliminary results of the Offer.

In connection with the completion of the Offer, Cadeler has, in consultation
with the Oslo Stock Exchange, decided to request that trading in the Cadeler
Shares on the Oslo Stock Exchange be suspended with effect from the first day of
trading of the Cadeler plc shares on the Oslo Stock Exchange, which is expected
to be on or around 5 November 2026. The last day of trading in the Cadeler
Shares on the Oslo Stock Exchange is accordingly expected to be on or around 4
November 2026.

The suspension is being implemented to avoid simultaneous trading in the shares
of both Cadeler and Cadeler plc on the Oslo Stock Exchange during the period
until the Cadeler Shares are delisted, including the period prior to
commencement of the Squeeze-out (as defined below).

As announced earlier today, Cadeler plc intends, as promptly as practicable, to
initiate 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, and following completion of the Offer, 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, against payment of cash consideration, within
a four-week period, with both the cash consideration and the four-week period
set out in such notice. 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 against payment of the cash consideration.

Shareholders of Cadeler who did not tender their Cadeler Shares in the Offer
will not be able to trade their Cadeler Shares on the Oslo Stock Exchange after
the last day of trading. The suspension will not affect the Squeeze-out, and the
remaining shareholders of Cadeler will receive the cash consideration in the
Squeeze-out irrespective of the suspension.

The suspension is expected to remain in effect until the Cadeler Shares are
delisted from the Oslo Stock Exchange. Cadeler intends to hold an extraordinary
general meeting following expiry of the Squeeze-out period to approve the
delisting of the Cadeler Shares from the Oslo Stock Exchange. The delisting will
be subject to an application to, and approval by, the Oslo Stock Exchange
following completion of the Squeeze-out. Cadeler will remain subject to its
disclosure obligations as an issuer listed on the Oslo Stock Exchange until the
delisting has become effective.

Further, trading of the Cadeler ADSs on the New York Stock Exchange is expected
to be suspended before market open on or around 5 November 2026, with delisting
of the Cadeler ADSs from the New York Stock Exchange taking effect 10 days
thereafter. Cadeler's American Depositary Receipt programme will be terminated
thereafter.

Shareholders of Cadeler who have validly tendered their Cadeler Shares
(including Cadeler Shares represented by Cadeler ADSs) in the Offer will receive
Cadeler plc shares, which are expected to be admitted to trading on the Oslo
Stock Exchange and the New York Stock Exchange on or around 5 November 2026, and
will thus be able to trade in Cadeler plc shares from such date.

Forward-Looking Statements

This communication includes forward-looking statements with respect to the
proposed Redomiciliation and Offer, including statements regarding the

"potentially," "estimate," "continue," "anticipate," "intend," "could," "would,"
"should," "project," "target," "plan," "expect," or the negatives of these terms
or variations of them or similar terminology. The absence of these words,
however, does not mean that the statements are not forward-looking. These
forward-looking statements are based upon current expectations, beliefs,
estimates and assumptions that, while considered reasonable as and when made by
Cadeler plc and its management, and Cadeler and its management, as the case may
be. Such forward-looking statements are subject to risks, uncertainties, and
other factors that could cause actual results to differ materially from those
expressed or implied by such forward-looking statements. New risks and

all risks and uncertainties. Neither Cadeler plc nor Cadeler undertakes any
obligation to update any such statements in light of any future event or

the risk that the Offer is subject to conditions, not all of which are within
Cadeler plc's control. The foregoing is not exhaustive. There can be no
assurance that future developments affecting Cadeler plc, Cadeler or the Cadeler
Group will be those that the Cadeler Group has anticipated.

that may cause actual results or performance to be materially different from
those expressed or implied by these forward-looking statements or from
