Mainmark announces the completion of a strategic alliance with Mitsui & Co.

Mainmark announces the completion of a strategic alliance with Mitsui & Co., Principal Investments Ltd. (MCPI), a wholly owned subsidiary of Mitsui & Co., Ltd, following the sale of its Japan operations to a fund managed by MCPI.

This alliance will establish a formal framework for collaboration between the two organisations, focused on advancing technical capability, expanding market access, and strengthening delivery of ground engineering solutions internationally.

As part of the transaction, MCPI will assume independent operational control of the Japanese jurisdiction under a branding and strategic alliance arrangement, while leveraging Mitsui & Co. Group’s network and support structure. Mainmark will retain full operational control of all other global regions, with no change to existing operating structures outside Japan.

The alliance aligns with Mainmark’s long-term strategy to expand global capability, strengthen technical leadership, and support sustainable international growth.
