Gulf Marine Services plc

Publication of Prospectus and Notice of General Meeting

Further to the announcements earlier today by Gulf Marine Services plc (LSE: GMS) ("GMS", the "Company" or, together with its subsidiary undertakings, the "Group") relating to Capital Raising, the Company announces that the Prospectus has been published today, having received approval from the Financial Conduct Authority, and is available on the Company's website at www.gmsplc.com.

The Prospectus includes a notice convening a General Meeting to be held at 2.00 p.m. (UAE time) on Friday, 25 June 2021 at Gulf Marine Services WLL, Office 403, International Tower, 24th (Karama) Street, Abu Dhabi, United Arab Emirates.

Capitalised terms not otherwise defined in this announcement have the meanings given to them in the announcement made by the Company at 7.00 a.m. this morning.

General Meeting

Due to the continued unpredictability caused by the COVID-19 pandemic, the uncertainty relating to the lifting of the coronavirus restrictions, and with the safety and well-being of the Company's Shareholders and employees in mind, the Board are planning to hold the General Meeting with the minimum attendance required to form a quorum. As such, the Board expect only one Director and another Company-designated shareholder representative to be in attendance at the venue for quorum purposes in order to conduct the business of the meeting. Shareholders and others are unlikely to be able to attend the General Meeting in person and are therefore strongly encouraged not to attend and to cast their votes by proxy appointing the Chairman of the meeting as proxy to vote on their behalf. The Board will continue to closely monitor the developing impact of COVID-19, including the latest guidance from the Abu Dhabi and UK Governments, and should the Board consider it necessary or appropriate to revise the current arrangements of the General Meeting to permit Shareholder attendance, this will be notified to Shareholders on the Company's website and via a Regulatory Information Service as soon as possible before the date of the General Meeting. If Shareholders are permitted to attend the General Meeting, appropriate social distancing and other protective measures will be applied, and the Board may require that such Shareholders provide prior advance warning of their proposed attendance.

Availability of the Prospectus

Copies of the Prospectus and the Form of Proxy in relation to the General Meeting, and certain other documents in relation to the Capital Raising, are available for inspection on the Company's website www.gmsplc.com. Mailing of the Prospectus and Proxy Form will commence today.

Copies of the Prospectus and the Form of Proxy in relation to the General Meeting have also been submitted to the Financial Conduct Authority via the National Storage Mechanism and will be available for viewing shortly at https://data.fca.org.uk/#/nsm/nationalstoragemechanism.
