THE HENDERSON SMALLER COMPANIES INVESTMENT TRUST PLC

General Meeting held on Wednesday, 4 March 2026

The Henderson Smaller Companies Investment Trust plc (the "Company") announces that, at the General Meeting held at 9.30 am on Wednesday, 4 March 2026, the special resolution set out in the Notice of General Meeting issued on 28 January 2026 was duly passed on a poll.

The resolution authorises the Company to undertake market purchases of the Company's ordinary shares of up to a maximum of 8,674,958 (or if less, 14.99% of the number of ordinary shares in issue (excluding shares held in Treasury) immediately prior to the passing of this resolution), at the maximum price per share (exclusive of expenses) not exceeding the higher of: a) 105% of the average middle market quotations for the five business days preceding the date of purchase; and b) the higher of the last independent bid and the highest current independent bid on the London Stock Exchange. This authority shall expire at the conclusion of the next Annual General Meeting, expected to be held in October 2026.

The poll results received were as follows:

For the purposes of s341 Companies Act 2006, the votes validly cast are expressed in the table above as a percentage of the Company's total voting rights as at close of business on 2 March 2026, being the time at which a shareholder had to be registered in the register of members to attend and vote at the General Meeting. A vote 'withheld' is not a vote in law and has therefore not been counted as a vote 'for' or 'against' any resolutions.

The aggregate number of ordinary shares in issue at the date of this announcement is 74,385,131, of which 16,834,663 were held in Treasury at close on 3 March 2026. Each ordinary share carries one vote.

The full poll results will also be available on the Company's website at www.hendersonsmallercompanies.com. The full text of the resolution is in the Notice of General Meeting issued on 28 January 2026 and also available on the Company's website. The special business resolutions will be submitted to the National Storage Mechanism ("NSM") and will shortly be available for inspection on the NSM website at https://data.fca.org.uk/#/nsm/nationalstoragemechanism.
