HENDERSON OPPORTUNITIES TRUST PLC

Payment of first interim dividend

On 7 March 2024, prior to the share split being approved by shareholders, Henderson Opportunities Trust plc (the "Company") declared a first interim dividend of 7.5 pence per ordinary share of 25p each, in respect of the quarter to 31 January 2024 for the period ending 31 October 2024.

As the 5 for 1 share split has now become effective the Company clarifies that the interim dividend equates to 1.5p per ordinary share of 5p each. The aggregate dividend to be paid for every five shares held post share split remains the same (i.e. 7.5p) as if one ordinary share of 25p each had been held. The dates for the dividend remain unchanged.

The dividend will be paid on 20 June 2024 to shareholders registered at the close of business on 17 May 2024. The Company's shares will go ex-dividend on 16 May 2024.
