Important information

Gore Street Energy Storage Fund plc (ticker: GSF), London's first listed energy storage fund investing in income producing assets in the UK and internationally announces that further to the announcement on 31 July 2019, the Company has in total raised gross proceeds of approximately £30.9m in its latest fundraising campaign, thereby over doubling the available capital for GSF to deploy in energy storage assets since IPO. This total includes gross proceeds of £5.91 million by way of an Initial Placing and Offer for Subscription (the "Fundraise") together with an additional £25m commitment from the National Treasury Management Agency ("NTMA")¹ to be drawn upon as announced on 5 June 2019 which will give Gore Street considerable funds available for investment.

Since IPO in May 2018, following this fundraise, Gore Street has more than doubled in size to approximately £62m assets under management and has built a portfolio of 189MW across eight assets in the UK and the Republic of Ireland. GSF has an additional 500MW in pipeline in UK, Ireland and continental Europe, which it intends to execute against in the coming months.

Applications have been received under the Fundraise for 6,497,267 Ordinary Shares which will be issued at a price of 91 pence per Ordinary Share. Of these, 3,821,763 Ordinary Shares will be issued under the Initial Placing and 2,675,504 Ordinary Shares will be issued under the Offer for Subscription. The Fundraise included a subscription by the NTMA of 1,624,300 Ordinary Shares. This is in addition to their commitment to invest a further £25 million Additional NTMA Subscription pursuant to the terms of the NTMA Subscription Agreement. Also, further to the announcement on 16 July, the Fundraise includes a subscription by NEC Energy Solutions Inc., a related party of the Company, for 1,098,901 Ordinary Shares.

The proceeds of the Initial Issue will be used to invest in a diversified portfolio of utility scale energy storage projects and in particular the projects in Northern Ireland and the Republic of Ireland as set out in the Prospectus. To augment the proceeds of the Initial Issue, as referenced in the announcement on 31 July, the Company is well placed with funding sources for the Irish projects through the Placing Programme from investors which have expressed interest in the Initial Issue but have not been able to invest at this time, from other investment vehicles which are controlled by or have appointed as their investment adviser, the Adviser and through debt providers.

Applications will shortly be open for investors to subscribe for Ordinary Shares at the Issue Price of 91 pence per Ordinary Share pursuant to the Intermediaries Offer. Only the Intermediaries' retail investor clients in the United Kingdom are eligible to participate in the Intermediaries Offer. Investors may apply to any one of the Intermediaries to be accepted as their client.
