The company has signed a definitive agreement to acquire 100% equity stake in MBJ through a wholly owned special purpose vehicle to be incorporated in Japan. The transaction is expected to close in Q2 FY27, subject to regulatory approvals and customary closing conditions.

MBJ is engaged in fermentation-based research, development and manufacturing of pharmaceuticals, specialty chemicals and CDMO services. The Japanese company has capabilities across oncology APIs, plasmid DNA manufacturing, ADC conjugation and biologics.

MBJ reported estimated revenue of JPY 9.5 billion, or around Rs 570 crore, for FY26. Around 40% of its revenue comes from overseas markets outside Japan.

Gujarat Themis said the acquisition marks a strategic step in its transition from a fermentation-led intermediates business to a technology-driven Contract Development and Manufacturing Organisation (CDMO) platform focused on precision fermentation and next-generation drug manufacturing.

The company added that the deal will provide access to MBJ’s proprietary technologies, global customer relationships and regulated manufacturing infrastructure. Two of MBJ’s three manufacturing facilities in Japan have undergone audits by the US FDA and Japan’s PMDA.

The acquisition is proposed to be funded through a mix of debt and equity and is expected to be earnings accretive.
