Milbank LLP advised Vietnamese conglomerate Masan Group Corporation and its portfolio companies in the sale of 100% of H.C.

The transaction is expected to close promptly following the attainment of regulatory approvals.

Starkâs business operations. Masan will also retain ownership in Nyobolt, a UK-based fast-charging lithium ion battery company, and potential monetary upside from future commercialization of H.C. Starckâs black mass technology and intellectual property.
