BMZ German divisions start restructuring plan

The immediate trigger behind the insolvency is the loss of a major customer in the stationary energy storage segment, which reportedly led to a sudden liquidity crisis and triggered legal disputes and unforeseen costs. BMZ has not disclosed the identity of the client. The group emphasized that this development affects only the German operations, while its international subsidiaries remain fully operational.

The company’s plan, according to its official release, is to maintain operational continuity while restructuring the German business into a new organizational framework, preserving customer relationships and ongoing contracts. Financial stability is being supported by a bridge financing package from the group’s shareholders, with further funds earmarked for recapitalization.

As reported on Battery-Tech.net, “the process will conclude with a restructuring plan that includes carving out the operational activities of BMZ Germany GmbH into a new entity. The group emphasized that other core business units will remain outside the insolvency process and continue normal operations”.
