“The financial statements are prepared on the assumption of going concern. The Company has maintained a high profitability level in 2025, and the profit for the year 2025 was in line with 2024. The markets have continued to be strong during 2025 and based on the Group's high backlog and the budgets for the next 12 months, the Board of Directors is of the opinion that the Company is a going concern. Furthermore, the Directors have obtained confirmation from the parent Company, DOF Subsea AS, that it will provide the necessary support to enable the Company to meet its obligations as they fall due. The confirmation is valid for a minimum of 12 months from the date of approval of the financial statements.”
