Going concern
Material uncertainty disclosed

“The financial statements have been prepared on a going concern basis notwithstanding net liabilities at 31 December 2025 of £195.4 million and a loss before tax for the year of £33.5 million. We draw attention to note 1.2 to the financial statements which indicates that there is a downside risk of a breach of one of the financial covenants under the Company’s external loan; that downside risk has also resulted in a material uncertainty in relation to the ability of the Company’s ultimate parent Dolphin Drilling AS, to continue as a going concern.”
