Re: Dividend Announcement

The Directors of TwentyFour Select Monthly Income Fund Limited (“SMIF”), the listed, closed-ended investment company that invests in a diversified portfolio of credit securities, have declared that a dividend of 0.5 pence per share will be paid, in line with the Prospectus, representing the regular monthly targeted dividend for the financial period ended 30 June 2026 as follows: Ex-Dividend Date 16 July 2026Record Date 17 July 2026 Payment Date 31 July 2026 Dividend per Share 0.50 pence (Sterling)

Given the ongoing interest rate environment and volatility in the global markets, the Directors have given careful consideration to the Company's projected income for the year against their assessment of risks currently affecting the markets and those inherent in achieving its target dividend payment of 6 pence per share per annum. Based on this analysis the Directors believe that dividends payable in respect of the year ending 30 September 2026 are likely to be in excess of 6.5 pence per share.
