Webinar Today

The Board of Gore Street Energy Storage Fund plc announces that it has today published a circular (the "Circular") setting out in full its unanimous recommendation to vote against all the Requisitioned Resolutions, and details of the Company's response to the letters and accompanying notices dated 16 July 2025 from RM Funds.

For the reasons set out below, your Board unanimously recommends that you VOTE AGAINST ALL the Resolutions that RM Funds has proposed and urges you to vote your Shares.

• The Company is delivering on its investment mandate. It now has broadened the commercial operation of its full 924.1 MWh portfolio, which is more than doubling its cash-generating assets during 2025, across five diversified markets.
• The Company has a positive outlook, with a strategic plan to increase revenue from existing assets being executed by a strong and independent Board. In the 12 months to 30 June 2025 share price total return was 12.2¹ per cent., with further value creation anticipated.
• The Board believes that RM Funds’ activist intentions are self-serving and that RM Funds’ interests are not aligned with the interests of all Shareholders.
• Your Board has positioned the Company well for sustainable long-term value creation, and this would be at risk of being derailed by an activist investor via its nominees. One of RM Funds’ proposed nominees is an individual known for joining boards of investment companies to restructure and start a managed run-off of portfolios.
• An independent Board is critical in representing the interests of all Shareholders, and not the interests of one particular Shareholder. The Board is concerned that RM Funds’ selected nominees may not act completely independently of RM Funds.
• The Board has today announced separately, that it is implementing a clear and detailed strategy to enhance shareholder value and designed to close the gap between the share price and NAV.

A copy of the Circular has been submitted to the National Storage Mechanism and will shortly be available for inspection at https://data.fca.org.uk/#/nsm/nationalstoragemechanism and on the Company's website at https://www.gsenergystoragefund.com/.

The Circular contains a Notice of Requisitioned General Meeting to be held at the offices of Stephenson Harwood LLP, 1 Finsbury Circus, London EC2M 7SH at 1 p.m. on 20 August 2025.

The full text is also available here: http://www.rns-pdf.londonstockexchange.com/rns/0847T_1-2025-7-29.pdf.

Action to be taken in respect of the Requisitioned General Meeting

EVERY VOTE WILL COUNT AND EACH VOTE IS IMPORTANT - SHAREHOLDERS SHOULD ENSURE THEY VOTE TO HAVE THEIR SAY IN THE FUTURE OF THEIR COMPANY.

All Shareholders are encouraged to vote on the Resolutions to be proposed at the Requisitioned General Meeting and, if their Ordinary Shares are not held directly, to arrange for their nominee to vote on their behalf. Further details on how to vote are available in the Circular.
