The Regional CEOs contribute their significant expertise in coffee and business to the forum, actively participating in all discussions and deliberations to inform and support the decisions of the BoD.
Over the past year, NKG has continued to expand and strengthen its teams across the EMEA region as well as in the Americas and Asia Pacific. By decentralizing operations and integrating regional insights, NKG aims to enhance decision-making speed, foster collaboration, and unlock new growth opportunities. Since the introduction of the regional structure in early 2025, the company has made significant progress, says Group CEO David M. Neumann: “Of course, we still have a way to go, and optimization remains an ongoing process but I am confident that we are on the right track and that our teams are well positioned to drive NKG’s development in the regions.”
NKG’s regional teams for EMEA, Americas, and Asia Pacific bring together international experts from the fields of Operational Management, Finance, Controlling, HR, Tax, and IT. Led by the Regional CEOs, these offices serve as hubs for decision-making and strategic development tailored to their markets.
