Umicore SA Business Unit Precious Metals Refining (Umicore) - Conclusion of Incident Review Process
The Incident Review Process (IRP) was invoked against Umicore SA following LBMA’s quality control of its FY2024 independent assurance deliverables which flagged concerns regarding the assurance provider’s challenge of risk classification. A different assurance provider, Arche Advisors was appointed to repeat the FY2024 engagement as well as conduct the FY2025 engagement. The assurance work completed by the new assurance provider identified no zero‑tolerance non‑conformances for either year. Umicore remains a Good Delivery List Refiner. The IRP has been closed.
