## Questions

### Does MCPI invest from a fund or a corporate balance sheet?

MCPI invests from the corporate balance sheet of its parent, Mitsui & Co., and does not publicly raise third-party blind-pool funds. This permanent-capital structure eliminates fundraising timelines and fixed investment periods, granting the firm flexibility on entry timing, hold duration, and exit decisions. It also means MCPI does not report to external limited partners, a governance posture distinct from most Japanese private equity managers.

### What types of deals does MCPI typically execute?

The firm executes control buyouts—management successions, corporate divestitures, and public-to-private transactions—alongside minority growth positions where there is a strategic link to Mitsui's industrial divisions. Deal structures include direct equity, structured equity, and co-investments alongside other financial or corporate partners. MCPI's portfolio is weighted toward industrial, manufacturing, logistics, and branded consumer goods rather than capital-light software or services.

### What is MCPI's relationship with Mitsui & Co.'s broader investment portfolio?

MCPI operates as the dedicated domestic private equity unit within Mitsui & Co., distinct from the parent's principal investment group and its global commodities and infrastructure holdings. Its mandate is to execute control-oriented equity investments with active operational support, leveraging Mitsui's supply-chain access and industry experts inside Japanese portfolio companies. The unit reports into Mitsui's corporate structure rather than functioning as an autonomous external manager.

### Which sectors does MCPI explicitly avoid?

Based on disclosed portfolio positions, MCPI does not actively pursue early-stage venture, biotechnology, or heavy infrastructure projects — segments where Mitsui's parent-level teams or other subsidiaries take the lead. The domestic buyout portfolio shows no disclosed exposure to pure-play financial services, software-as-a-service, or real estate development, concentrating instead on operating businesses with tangible asset bases and industrial logic.
