Market Update: Spin-Out Subscription and Forward Capitalisation

Global InterConnection Group is delighted to announce that SwissASC has received a formal subscription commitment for £21.5 million from the Offerors, The Truell Conservation Foundation and the Truell Intergenerational Family Limited Partnership, a related party transaction, in support of the previously announced Swiss ASC Spin-Out transaction. The subscription is due and payable to ASC Energy Ltd on or before 30th August 2025. Swiss ASC is taking on the liabilities of GIG, as well as 80% of the Atlantic SuperConnection project.

Consequently, investors will be able to decide whether to submit RoFR Purchase Requests for settlement 1st September 2025 in accordance with the revised timetable set out below. If an investor wishes to submit earlier, their submission will be considered and processed on the basis of settlement three business days after receipt of the RoFR Purchase Request.

Importantly, those investors who have already submitted RoFR Purchase Requests (and Warrant holders electing to exercise), in line with the original timetable, will now have the opportunity to revisit and, if they choose, revise their elections prior to the updated settlement windows.

However, the RoFR subscription price has been revised upwards to reduce the discount for subscriptions received after 19th July from 40% of the face value of CLNs, to 65% of the face value of CLNs.

As set out in the Explanatory Note circulated to eligible investors, the issuer reserves the right to reject any RoFR Purchase Request at its sole discretion.

The expected timetable for investors deciding to submit RoFR Purchase Requests for settlement on or before 30th August 2025 is as follows:

Final Date for Subscription 27thAugust 2025 (17:00 CEST) Closing Date 28th August 2025 (17:00 CEST) Closing Allocation and Announcement 29th August 2025 Settlement 1st September 2025 Admission of CLNs to TISE 4th September 2025

Full details of the offer are available on the TISE: https://tisegroup.com/market/news/347163

This funding enables the Spin-Out, capitalises SwissASC to support its next phase of delivery for Atlantic SuperConnection and puts in place the funding for the long term management contract with the Company . The Spin-Out provides a clear pathway to through to Final Investment Decision (FID) for Atlantic SuperConection, and positions GIG to continue its progress on key infrastructure platforms, including our strategic partnership with Scale 42.
