## Questions

### What types of transactions does Marathon Capital Partners execute in Japan?

The firm's disclosed strategy spans buyouts, growth equity, expansion capital, and succession-driven recaps. It targets Japanese middle-market companies where founder retirement or corporate carve-outs create entry opportunities. The approach includes both control acquisitions and significant-minority positions in cash-flow-positive businesses.

### Is Marathon Capital Partners a domestic Japanese fund or a global firm?

Marathon Capital Partners is headquartered in Tokyo and focuses exclusively on the Japanese market. It operates as a domestic private equity manager rather than the Tokyo office of a global platform. This local structure is typical of the generation of independent Japanese GPs formed to address succession-driven deal flow.

### What differentiates Marathon Capital Partners from global mega-funds active in Japan?

As a Japan-domiciled GP, Marathon Capital Partners offers a culturally aligned, long-horizon partnership model that contrasts with the standard 3-to-5-year global fund timeline. This matters in succession transactions where founder-owners prioritize stewardship continuity. The firm's broad mandate — spanning buyout, growth, and early-stage — also provides greater structural flexibility than narrowly mandated global competitors.
