Update on the Judicial Review for the Islandmagee Gas Storage Project

Harland & Wolff Group Holdings plc (AIM: HARL), the UK quoted company focused on strategic infrastructure projects and physical asset lifecycle management, provides an update on the Judicial Review (JR) in connection with the marine licence for the Islandmagee gas storage project.

The Company has been informed by the court that some of the affidavits were submitted late by the applicant (No Gas Caverns Limited) and the respondent (Department of Agriculture, Environment and Rural Affairs) had lengthy affidavits of its own to submit in its defence. Given the complexity and voluminous documentation to be submitted to the courts, a request was made to the court to delay the hearing so that all affidavits could be submitted in good order. The court has, therefore, granted an extension and the hearing will now be held on 16 January 2023.

The Company will make further announcements on the JR and other commercial matters in due course.

John Wood Chief Executive Officer commented "An extension to the hearing date is disappointing as we are keen to get this matter resolved and move the project to its next stage of development especially since we are in a national energy crisis. A fast cycle storage project like Islandmagee is exactly what the country needs at this time. Regardless of the extension to the hearing date, we remain confident of a positive outcome in January 2023."

About Harland & Wolff

Harland & Wolff is a multisite fabrication company, operating in the maritime and offshore industry through five markets: commercial, cruise and ferry, defence, energy and renewables and six services: technical services, fabrication and construction, decommissioning, repair and maintenance, in-service support and conversion.

Its Belfast yard is one of Europe's largest heavy engineering facilities, with deep water access, two of Europe's largest drydocks, ample quayside and vast fabrication halls. As a result of the acquisition of Harland & Wolff (Appledore) in August 2020, the company has been able to capitalise on opportunities at both ends of the ship-repair and shipbuilding markets where there will be significant demand.

In February 2021, the company acquired the assets of two Scottish-based yards along the east and west coasts. Now known as Harland & Wolff (Methil) and Harland & Wolff (Arnish), these facilities will focus on fabrication work within the renewables, energy and defence sectors.

In addition to Harland & Wolff, it owns the Islandmagee gas storage project, which is expected to provide 25% of the UK's natural gas storage capacity and to benefit the Northern Irish economy as a whole when completed.
