Yangzijiang Shipbuilding has agreed to acquire a 10% equity stake in Poseidon Corp, the holding company of independent containership owner and operator Seaspan Corporation, in a deal valued at $825.7m.
The transaction, structured through two conditional share purchase agreements, represents a clear move toward strategic vertical integration for the Chinese shipbuilder.
Yangzijiang said Seaspan is already a long-standing and important customer of the group, and that the investment is intended to reinforce the relationship, create closer long-term alignment and better connect vessel demand with the company’s production planning and shipyard development strategy.
The company also described the transaction as a way to deploy surplus funds into a long-term strategic asset with relatively stable return characteristics.
The move reflects Yangzijiang’s broader ambition to strengthen its position across the maritime value chain while securing deeper ties with a major containership leasing player. It also comes during a week of major activity around Poseidon, with Ocean Network Express increasing its own stake in the holding company to 48.9%.
