("Gresham House", the "Company" or the "Group")

Completion of Acquisition of Appian Asset Management to establish Gresham House Ireland

Gresham House (AIM: GHE), the specialist alternative asset manager, is pleased to announce the completion of the acquisition of Appian Asset Management Ltd ("Appian"), following regulatory approval from the Central Bank of Ireland (the "Acquisition").

Based in the Republic of Ireland, Appian is an active asset manager with c.€350 million in Assets Under Management (AUM) as at 31 December 2020. The Acquisition enhances the Group's capabilities to develop existing strategies in Ireland and Europe, particularly those with a sustainability focus including forestry, sustainable infrastructure and real estate.

Appian's existing funds complement those offered by Gresham House and will benefit from the support of the Gresham House brand, infrastructure and central resources. In addition, the ambition to increase its presence in alternative asset classes dovetails with the Group's existing forestry asset management platform and growth strategy in Ireland.

The Acquisition forms part of the Group's international expansion plans as the addition of a regulated EU-based platform post-Brexit. It accelerates Gresham House's growth plans, as set out in its five-year strategy GH25, and is expected to be earnings enhancing for the Group with potential further value creation through synergies and identified growth initiatives.

Application will be made for the admission to trading on AIM ("Admission") for 104,168 new ordinary shares of 25p each in the Company ("Ordinary Shares") to be issued as part of the initial consideration for the Acquisition. It is anticipated that the new Ordinary Shares will be admitted to trading on AIM on or around 5 July 2021.

Following Admission, the Company's issued share capital will comprise 32,945,875 Ordinary Shares, this figure may be used by shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change in their interest in, the share capital of the Company under the FCA's Disclosure and Transparency Rules.

Appian will be known as Gresham House Ireland going forward, subject to regulatory and other approvals.
