CASE CASSIOPEA in cooperation with ABN AMRO acted as the exclusive financial adviser to Erdgas Münster on the sale of Nowega to Igneo Infrastructure Partners
10. November 2026
Erdgas Münster GmbH (“EGM”), ultimately owned by ExxonMobil, Harbour Energy, Shell, Neptune Energy and Vermilion Energy, has entered into a binding agreement to sell 100% of Nowega GmbH (“Nowega”), a gas transmission system operator (“TSO”) in Germany, to Igneo Infrastructure Partners.
Headquartered in Münster, Germany, and with approximately 150 employees, Nowega is a mid-sized gas TSO, which owns, operates, maintains and markets approximately 1,500 kilometres of high-pressure gas pipelines. Its network extends from the Dutch border across Lower Saxony and parts of North Rhine-Westphalia to the Wendland region and forms part of both Germany’s national gas transmission system and the intra-European transport routes for gas. It transports natural gas and hydrogen to industrial customers, utilities and distribution networks and is strategically located close to major industrial demand centres and north Germany’s key hydrogen production and import clusters.
EGM is a German gas infrastructure company headquartered in Münster, North Rhine-Westphalia. It operates an approximately 740-kilometre high-pressure pipeline network through which around half of Germany's domestically produced natural gas is transported.
Commenting on the successful transaction, Stephan Dietzmann, Managing Director of EGM, said: “CASE CASSIOPEA and ABN AMRO provided highly committed and hands-on support throughout the process. Their deep sector expertise and strong execution capabilities were instrumental in navigating a complex transaction and achieving an excellent outcome.”
CASE CASSIOPEA in cooperation with ABN AMRO acted as the exclusive financial adviser to EGM and its ultimate shareholders ExxonMobil, Harbour Energy, Shell, Neptune Energy and Vermilion Energy.
The transaction is expected to close in the first quarter of 2027, subject to customary regulatory approvals.
