Termination of Discussions with RMII

In the Company's announcement on 11 August 2023, the Board of GCP Infra announced that it was in discussions with the Board of RM Infrastructure Income plc ("RMII") regarding a potential combination (the "RM Scheme").

The Board of GCP Infra has been unable to agree on structure and terms with RMII in respect of the RM Scheme that are acceptable to both parties. GCP Infra has therefore notified RMII of the termination of discussions relating to the RM Scheme.

As per its announcement on 11 August, GCP Infra remains in discussions with the board of GCP Asset Backed Income Fund Limited ("GABI") in respect of a proposed combination of GCP Infra with GABI (the "GABI Scheme"). Heads of Terms have been agreed and a shareholder feedback exercise is being conducted. A circular to shareholders of the Company, providing further details of the Proposals and convening a general meeting to approve the Investment Policy Change, alongside a prospectus, is expected to be published in due course.
