2024 ANNUAL REPORT AND NOTICE OF 2025 ANNUAL GENERAL MEETING

In compliance with UK Listing Rule 6.4.1R, the Company announces that the Annual Report & Accounts of the Company for the year ended 31 December 2024, the Circular to shareholders of the Company, including Notice of the Annual General Meeting ("AGM"), and the form of proxy for use at the AGM, have been submitted to the National Storage Mechanism in unedited full text and will shortly be available for inspection at:

The Company's AGM will be held at 2:30 pm (UAE time) on Thursday 29 May 2025 at the offices of Gulf Marine Services WLL, Office 403, International Tower, 24th (Karama) Street, Abu Dhabi, United Arab Emirates.

The Annual Report & Accounts 2024 (in pdf and ESEF format), the AGM Notice and form of proxy are now available on the Company's website at www.gmsplc.com.  

Hard copies of the above documents will be mailed to those shareholders having elected to receive paper copies.

The Board recognises that the AGM is an important event for shareholders in the corporate calendar and is committed to ensuring that shareholders can exercise their right to vote and ask questions in connection with this meeting. Accordingly, for those shareholders who do not wish to or unable to attend, questions in connection with the business of the AGM can be submitted on reasonable notice by email to [email protected] in advance of the AGM and, in so far as relevant to the business of the meeting, questions will be responded to by email and taken into account as appropriate at the meeting itself.  We are not planning to have a Directors' presentation at the AGM and it will be held strictly to conduct the business of the AGM.

Voting at the AGM will be by way of a poll so that all the votes cast in advance by shareholders appointing the Chairman of the Meeting as their proxy to vote on their behalf can be taken into account. Shareholders have one vote for each ordinary share held when voting on a poll and this procedure ensures that every vote can be cast.

Shareholders wishing to vote on any of the matters of business at the AGM are encouraged to submit their votes as soon as possible in advance of the meeting and in any case, by 11.30am (UK time) on 27 May 2025 through the proxy and electronic voting facilities and to appoint the Chairman of the meeting as their proxy for this purpose. Further details are included in the Notice of the AGM.

The results of the AGM will be announced as soon as practical after it has taken place.

Notes to Editors:

Gulf Marine Services PLC, a company listed on the London Stock Exchange, was founded in Abu Dhabi in 1977 and has become a world‐leading provider of advanced self‐propelled self‐elevating support vessels (SESVs). The fleet serves the offshore energy industries from its offices in the United Arab Emirates, Saudi Arabia, Qatar and the United Kingdom. The Group's assets are capable of serving clients' requirements across the globe, including those in the Middle East, Europe, South East Asia, West Africa, North and South America, and the Gulf of Mexico.

The GMS fleet of 14 SESVs is amongst the youngest in the industry. The vessels support GMS's clients in a broad range of offshore platform refurbishment and maintenance activities, well intervention work, and offshore wind turbine maintenance work (which are opex‐led activities), as well as offshore platform installation and decommissioning and offshore wind turbine installation (which are capex‐led activities).

The SESVs are categorised by size ‐ K‐Class (Small), S‐Class (Mid), and E‐Class (Large) ‐ with these capable of operating in water depths of 45m to 80m depending on leg length. The vessels are four‐legged and are self‐propelled, which means they do not require tugs or similar support vessels for moves between locations in the field; this makes them significantly more cost‐effective and time‐efficient than conventional offshore support vessels without self‐propulsion. They have a large deck space, crane capacity, and accommodation facilities (for up to 300 people) that can be adapted to the requirements of the Group's clients.
