Press Release

Cadeler Further Strengthens its Financial Position with Additional Capacity Under its Upsized Green Corporate Loan Facility with HSBC Group and Standard Chartered as Lenders

Copenhagen, August 26, 2024 – Cadeler A/S (“Cadeler”) today announces that it has further increased the capacity available to it under its unsecured green corporate term loan facility (the “Green Corporate Loan Facility”), with the commitments thereunder increased by EUR 45 million, bringing the total capacity available to Cadeler under the Green Corporate Loan Facility to EUR 125 million.

Standard Chartered is the lender on the upsizing of the facility. The two banks are also participating in Cadeler’s EUR 425m Facility, which is the post-delivery financing of the P-Class vessels.

Prior to the upsizing of the Green Corporate Loan Facility, Cadeler had drawn EUR 80 million thereunder, with remaining EUR 20 million headroom under the accordion. With today’s announcement, a further EUR 45 million in committed funds has been confirmed, increasing the total capacity of the Green Corporate Loan Facility and the total committed funds thereunder to EUR 125 million. HSBC acted as Sole Mandated Lead Arranger, Green Loan Coordinator, and Facility Agent.

With this upsizing, Cadeler has increased its financial flexibility and ability to seize market opportunities as they rise. This increase in unsecured, committed funds further strengthens Cadeler’s financial position and growth prospects and will enable it to fund a variety of wind turbine installation activities.
