Gulf Marine Services PLC, down 6.7% at 18.81 pence, 12-month range 14.66p-24.30p. Reports higher revenue in 2025 but flags rising uncertainty due to geopolitical tensions, with its 2026 outlook under review. The company says revenue rises 12% to $188.1 million from $167.5 million, while pretax profit falls to $35.8 million from $43.2 million. Gulf Marine adds that escalating conflict in the Gulf region is increasing volatility in oil and gas markets and causing disruptions to offshore operations, including a customer’s force majeure declaration. As a result, the group says its previously guided $105 million to $115 million adjusted Ebitda range for 2026 is now under assessment. Despite the uncertainty, the company notes improved day rates and a strong backlog, but cautions that the evolving geopolitical situation creates significant uncertainty over its operational and financial outlook.
