Amentum has recently completed a supplier ID restructure that might have impacted your previously used supplier ID. All data associated with your legacy ID has been transferred to your new ID with no impact to your PO’s or payments. Please direct any questions to your buyer or the supplier management team (suppliermanagement@amentum.com)
