Continuation of Share Buyback Programme

River UK Micro Cap Limited (the "Company") is pleased to announce that it has appointed Singer Capital Markets Securities Limited to manage an irrevocable share buyback programme (the "Share Buyback Programme") to buy back ordinary shares of no par value ("Ordinary Shares") for up to a maximum aggregate consideration of £2.0 million and subject to Ordinary Shares being available to purchase at a price representing a discount of 8.0 per cent. to the most recently announced NAV per share prevailing at the time of repurchase, alongside other certain pre-set parameters.

The Share Buyback Programme will commence today, and any shares repurchased pursuant to the Share Buyback Programme will count towards the Company's general buy back authority of 14.99 per cent. of the Company's issued share capital, as approved at the Company's last annual general meeting on 11 March 2026.

Under the Buyback Programme, the repurchased shares will be held in treasury at the Company's discretion for later cancellation. Shares held in treasury are not entitled to dividends and have no voting rights at the Company's general meetings.

The Company confirms that it currently has no inside information.
