5 November 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 on 29 October 2026 regarding the contemplated suspension of trading in the Cadeler Shares.

The suspension is being implemented to avoid simultaneous trading in the shares of both Cadeler and Cadeler plc (ticker: "CDLR" and ISIN GB00BN49H029) 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).

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

As announced in the stock exchange announcement made by Cadeler on 29 October 2026, 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, Cadeler plc will publish a notice on or about 9 November 2026 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.

The suspension will 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

Shareholders of Cadeler who have validly tendered their Cadeler Shares (including Cadeler Shares represented by Cadeler ADSs) in the Offer have received Cadeler plc shares, which are expected to be admitted to trading and be tradeable on the Oslo Stock Exchange and the New York Stock Exchange today, 5 November 2026.
