## Questions

### What is iSigma Capital's core investment strategy?

iSigma executes control-oriented buyouts in the Japanese middle market, including management buyouts, management buy-ins, and take-privates. It focuses on succession-driven transitions and corporate carve-outs where the firm can acquire a majority stake and actively manage the business through a generational handoff or restructuring.

### What types of companies does iSigma target?

iSigma targets cash-flow-positive businesses with established market positions, usually in sectors such as industrial manufacturing, niche technology, healthcare services, business services, and consumer goods. The firm looks for situations where a change in capital structure or leadership can improve performance — not turnaround situations alone.

### Does iSigma Capital make minority investments or growth-capital deals?

No. iSigma's disclosed strategy centers on control transactions. The firm acquires majority stakes in target companies through buyout structures, which distinguishes it from growth-capital or minority-focused investors in the Japanese market.
