Key takeaways • Revenue for the first three months of 2026 increased by EUR 59 million to EUR 125 million compared to the same period in 2025, primarily driven by higher contracted days following fleet expansion. • Revenue increase driven by higher contracted days from an expanded fleet, despite utilisation declining as available days increased faster due to fleet expansion and transition activity. Fleet utilisation decreased to 47.6% compared to 55.3% in Q1 2025 with adjusted utilisation of 77.7% compared to 79.4% in Q1 2025. • Cost of sales increased by EUR 53 million to EUR 98 million, driven mainly by the addition of three new operating vessels (Wind Ally, Wind Mover and Wind Keeper) compared to seven vessels in operation in the prior year. • SG&A increased as the organisation scaled onshore functions to meet the demands of an expanded fleet and continued project growth. • EBITDA increased by EUR 23 million to EUR 47 million, driven by higher revenue despite lower utilisation. • Vessel OpEx per day increased, driven by temporary project preparation costs and a small number of one-off items in Q1. | 13 1) Vessel OPEX per day based on crewing costs, technical costs and insurance. e en e Cost o sales ross pro it and other e penses peratin pro it Finance net ro it e ore inco e ta Inco e ta e pense ro it a ter ta I D essel per da o. o o ned essels eadco nt onshore era e Consolidated P&L for Q1 2026
