Publication of Circular

The Board of Smithson Investment Trust plc (the "Company") announces that it has today published a Circular (the "Circular") which contains notice of a general meeting of the Company (the "General Meeting"), at which the Board will seek shareholders' approval to renew the Company's share buy-back authority. The General Meeting will be held at 9.30 a.m. on 3 December 2025 at the offices of Apex Group, 4th Floor 140 Aldersgate Street, London, England, EC1A 4HY.

Since April 2022, the Company has undertaken regular share buy-backs while the Company's shares have been trading at a discount to the Company's net asset value per share. In the light of the Company's recent buy-back activity, the Board anticipates that the existing authority to repurchase shares (granted at the Company's last annual general meeting held on 23 April 2025) may be fully utilised before it can be refreshed at the Company's next annual general meeting, which is expected to be held in April 2026.

Accordingly, the Board wishes to convene the General Meeting in order to seek the necessary shareholder approval for a renewal of the Company's share buy-back authority prior to the 2026 AGM. The granting of such authority by shareholders will allow the Board to continue to operate the Company's share buy-back programme.

The Circular and the Notice of General Meeting are available on the Company's website at www.smithson.co.uk. A copy of the Circular will also be submitted to the National Storage Mechanism and will shortly be available for inspection at https://data.fca.org.uk/#/nsm/nationalstoragemechanism.
