Islandmagee Energy Judicial Review Update

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 Islandmagee Gas Storage Project Judicial Review (JR).

Following a recent review of the case, the parties have agreed to vacate the hearing dates of 16-20^th January 2023.

The new hearing is now listed for four days commencing 2 May 2023. Further updates will be made available in due course.

Harland & Wolff, group CEO John Wood, commented:

"Whilst it is disappointing that this has been delayed, we now have access to the majority of the submissions made and we remain confident that we will see a successful outcome to this review when it is undertaken in May.

As the UK continues to struggle to maintain adequate gas supplies in the UK there has never been a better time for this project to be developed."

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.
