Gemini – NDM Nominations

Updated: Friday 6 November 2026 - 1:10pm

Background

We have experienced an issue affecting NDM Nominations within Gemini, following recent Annual Quantity (AQ) data processing activities.

Our technical teams have identified discrepancies within the AQ data that is displayed within the Business Associate Balance and Nominations and Renominations Screens. Corrective action has been identified and is in progress to address the discrepancies ahead of the relevant close-out process today and minimise any further customer impact.

We will continue to monitor the situation and provide further updates.
