Letter from Seafox re Board Composition

The Company announces that it has received a letter from Seafox International Limited ("Seafox"), which owns approximately 29.9 per cent of the Company's shares. Seafox has asked that the Company's non-executive directors, Mr. Mike Turner (Senior Independent Director and RemCo Chairman), Mr. David Blewden (Audit Committee Chairman), Mr Mo Bississo and Dr. Shona Grant, voluntarily step down from the Board of GMS (the "GMS Board") and that the GMS Board appoint in their place three UAE-based individuals - Mr. Rashid Al Jarwan, Mr. Mansour Al Alami and Mr Saeed Mer Abdulla Khoory.

Seafox further stated that if the Company fails to implement its request by no later than 23 September 2020, it will requisition a General Meeting of Shareholders (a "General Meeting") to remove Mr. Turner, Mr. Blewden, Mr. Bississo and Dr. Grant, and to appoint Seafox's recommended candidates to the GMS Board.

The members of the GMS Board excluding the two Seafox representatives (for purposes of this announcement, the "Board"), have met to consider Seafox's letter.

The Board believes it is not in the best interests of the Company's shareholders for any of the current directors to resign.

None of the three candidates recommended by Seafox are known to the Board and it is not currently in a position to assess their suitability to be directors of a UK listed company or the value that they might bring to GMS.

As a result of Seafox's actions, the Board believes it now has no option but to put the plans for the equity capital raise on hold.

The Company has informed the UK Takeover Panel of Seafox's proposal, as it believes that these actions evidence an attempt by Seafox to take control of the Company. In this context, the Board is seeking clarification from both Mazrui International and Horizon Group whether or not they support Seafox's proposal in the light of their voting patterns with Seafox at the 2020 AGM.

The Board has written to Seafox to urge it to reconsider its proposed actions, which will give rise to a costly and value destructive exercise and significantly harm the interests of the Company's other shareholders.

The Company will provide a further update to the market in due course.

ABOUT GMS

GMS, 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 oil, gas and renewable energy industries from its offices in the United Arab Emirates and Saudi Arabia. The Group's assets are capable of serving clients' requirements across the globe, including those in the Middle East, South East Asia, West Africa, North America, the Gulf of Mexico and Europe.

The GMS fleet of 13 SESVs is amongst the youngest in the industry, with an average age of eight years. The vessels support GMS's clients in a broad range of offshore oil and gas platform refurbishment and maintenance activities, well intervention work and offshore wind turbine maintenance work (which are opex-led activities), as well as offshore oil and gas 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.

The Company's Legal Entity Identifier is 213800IGS2QE89SAJF77.
