YZJ Shipbuilding's stock surged 3.21% during intraday trading on Wednesday, following the company's announcement of a major strategic investment.

The Singapore-listed shipbuilder revealed plans to acquire a 10% stake in Poseidon, the holding company of containership owner and operator Seaspan Corp., for approximately $825.7 million. Seaspan is a long-term customer of Yangzijiang, and the deal is expected to strengthen collaboration between the two companies.

Yangzijiang stated that the investment will enhance alignment between vessel demand and its production planning and yard development strategy. The company also noted that the acquisition will provide closer access to end-market dynamics, enabling better market intelligence and responsiveness to customer demand. The transaction is intended to be funded with internal cash resources.
