    Dividend History

    Gamma has maintained a progressive dividend since IPO in 2014, increasing payments by 10-15% annually. Following the announcement on the proposed acquisition of the Group, the Group does not intend to declare or pay any further dividends prior to the effective date. It is also noted that the share buyback programme announced on 13 January 2026 is currently suspended, as the current share price is not within certain pre-set parameters agreed with Investec Bank plc, which was appointed to manage the share buyback programme.
