27 May 2026 08:00 CEST

Copenhagen, 27 May 2026: Cadeler A/S (OSE: CADLR / NYSE: CDLR) (“Cadeler”) today
announces the launch of a share buy-back programme of up to NOK 7.6 million
(approx. EUR 700,000) (the “Programme”), pursuant to the authorisation for the
acquisition of treasury shares granted by Cadeler’s shareholders to its Board of
Directors at the company’s general meeting held on April 21, 2026.

The Programme is to be implemented in accordance with Article 5 of Regulation
(EU) no. 596/2014 of the European Parliament and of the Council of April 16,
2014, as amended (the “Market Abuse Regulation”) and the Commission’s Delegated
Regulation (EU) 2016/1052 of March 8, 2016 (together with the Market Abuse
Regulation, the “Safe Harbour Rules”).

The purpose of the Programme is to enable Cadeler to meet its obligations to its
employees arising from certain of Cadeler’s share-based incentive programmes.

The Programme will be conducted in the period from 27 May 2026 until 5 June
2026, both days included, unless the maximum number of shares or repurchase
amount under the Programme is earlier reached. Cadeler may, however, suspend or
terminate the Programme at any time.

The following additional conditions apply to the Programme:

- The Programme will be managed by an independent lead manager on Cadeler’s
behalf. The independent lead manager will make its trading decisions regarding
the timing of the share repurchases independently of, and without influence
from, Cadeler.

- The maximum amount allocated to the Programme is NOK 7.6 million,
corresponding to approximately EUR 700,000.

- The maximum number of shares that may be acquired under the Programme is
105,275 shares, each with a nominal value of DKK 1.00.

- Shares acquired under the Programme may not be purchased at a price exceeding
the higher of (i) the share price of the last independent trade and (ii) the
highest current independent purchase bid on the trading venue where the purchase
is carried out.

- Purchases made on a single day may not exceed 25% of the average daily trading
volume on the trading venue where the purchases are made, calculated based on
the average daily traded volume during the 20 trading days preceding the date of
purchase.

Information about any shares acquired under the Programme will be published no
later than every seventh trading day on Cadeler’s investor relations website,
https://ir.cadeler.com, and by stock exchange announcements. Cadeler will
similarly publish information about subsequent amendments to the Programme (if
any), including any termination of the Programme.
