## Questions

### Who runs investment decisions at IA Partners?

The investment committee holds decision-making authority. Three members carry voting rights: President Harry Murakami and managing directors Chihiro Shima and Ryo Sato. Other managing directors and senior advisors, including Tadanobu Nishibayashi, Satoshi Tomii, and external counselors, contribute to deal evaluation without disclosed voting power.

### How does IA Partners source proprietary deal flow?

The firm targets corporate carve-outs and subsidiary divestitures directly from large Japanese companies. Its team's backgrounds in restructuring and spin-offs suggest relationships with corporate development and strategic planning divisions at Japanese conglomerates, though no specific origination channels or intermediaries are publicly disclosed.

### Does IA Partners participate in fund commitments or only direct deals?

The firm's disclosed activity focuses exclusively on direct investments — majority buyouts, minority stakes, and growth equity transactions in Japanese companies. There is no mention of fund-of-funds commitments, LP investments in external PE funds, or secondary market participation on its website.

### What investment stages does IA Partners typically target?

IA Partners targets mature businesses undergoing ownership transitions: corporate subsidiaries being divested, public companies going private, and businesses requiring restructuring. It does not disclose venture-stage or early-growth investments. The firm seeks control or significant influence through majority or large minority positions.
