Reference is made to the stock exchange announcement on 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), to
exchange each Cadeler Share for one (1) share in Cadeler plc in connection with
the contemplated redomiciliation of the Cadeler Group's parent company from
Denmark to the United Kingdom (the "Redomiciliation").

Further, reference is made to the combined EU/EEA prospectus and offer document
(the "Prospectus") published by Cadeler plc on 21 September 2026 in connection
the contemplated Redomiciliation. 

Based on information supplied to Cadeler plc prior to the publication of the
Prospectus, the Prospectus stated that Norwegian share savings accounts (Nw.:
aksjesparekonto) were ineligible to hold shares in Cadeler plc following
completion of the Offer and thus that any shares in Cadeler plc delivered to a
VPS account affiliated with a Norwegian share savings account upon completion of
the Offer would need to be transferred to an eligible VPS account or sold within
10 days of delivery. This statement can be disregarded. Shareholders that
currently hold their Cadeler Shares in a Norwegian share savings account (Nw.:
aksjesparekonto) are entitled both to receive and to continue to hold any
Cadeler plc shares they receive as consideration for such Cadeler Shares through
the Offer in their Norwegian share savings account indefinitely. Please note,
however, that any subsequent purchases of shares in Cadeler plc via the Oslo
Stock Exchange must be conducted through an ordinary VPS account and not a
Norwegian share savings account.

The information set out above does not apply to Cadeler plc's offer to acquire
the American Depositary Shares, each representing four (4) Cadeler Shares which
are admitted to trading and listing on the New York Stock Exchange, or to any
subsequent trading of the Cadeler plc shares on the New York Stock Exchange.

For further information regarding the offer, reference is made to the combined
EU/EEA prospectus and offer document, which is available at:
https://ir.cadeler.com/ and www.dnb.no/emisjoner, subject to regulatory
restrictions in certain jurisdictions. 

Any questions or requests for assistance concerning acceptance of the Offer
should be directed to the Receiving Agent (as defined in the Prospectus) on
