Copenhagen, 1 July 2025 -- Cadeler A/S (NYSE: CDLR / OSE: CADLR) today announces
that it has received a notice of termination from Ørsted A/S in relation to the
Long-Term Agreement for an A Class Windfarm Installation Vessel initially
disclosed on 8 April 2024. The agreement had secured A-Class vessel capacity
from Q1 2027 through the end of 2030. 

The termination of the Long-Term Agreement is principally a result of Ørsted's
decision to discontinue work towards the Hornsea 4 Offshore Wind Farm. 

Cadeler is entitled to agreed compensation as a consequence of the termination
of the Long-Term Agreement. In addition, Cadeler is now free to deploy the
vessel on alternative projects currently under discussion with third parties.
Cadeler does not believe that the termination of the Long-Term Agreement will
adversely affect Cadeler's long-term financial performance. Receipt of the
termination compensation noted above will positively impact financial guidance
for the 2025 calendar year.

Update to 2025 Guidance

Cadeler is revising upwards its revenue guidance for the financial year ending
December 31, 2025, with full-year revenue now expected to be within the range of
EUR 588 million and EUR 628 million (previously expected to be within the range
of EUR 485 million and EUR 525 million). In addition, Cadeler is revising
upwards its EBITDA guidance for the financial year ending December 31, 2025,
with full-year EBITDA now expected to be within the range of EUR 381 million and
EUR 421 million (previously expected to be within the range of EUR 278 million
and EUR 318 million.
