The Company is also reporting the completion of the name change process2 from Meridian Mining UK Societas to Meridian Mining Plc, effective for trading purposes, at market open on December 10, 2025. The change is due to the Company's November 2025 conversion to a public limited company ("PLC") in the United Kingdom, as voted on by shareholders at the Annual & Special Meeting3. As such, the Company's ISIN has changed to GB00BVPND783, and concurrently, the Company's CUSIP has changed to G6017H 103. The previous ISIN and CUSIP numbers are now inactive. There is no change in the trading symbols or share capital.
Mr. Gilbert Clark, CEO, comments: "I would like to congratulate David on accepting the full-time role as the Company's CFO. The expansion of Meridian's finance team's capacity since his tenure as Interim CFO has been exceptional, and it is well on its way to being ready for the demands of Cabaçal's future project financing. I am very pleased that Catherine has joined our Executive team. She brings a wealth of corporate and legal experience to the Company. At the same time as these welcome additions, we have a departure with Mariana leaving the Company. I would like to thank her for her strong contribution to the Company's success during a period of major growth for Meridian and we all wish her our very best in her new role."
"Lastly, the name change to Meridian Mining Plc reflects our United Kingdom base and the final administrative closure related to Brexit. We are now focused on rolling out Cabaçal's DFS and the greater exploration upside in 2026."
