## Questions

### Who runs investment decisions at Milestone Investisseurs?

Investment decisions are controlled by the two managing partners, Erick Rinner and Olivier Antomarchi, who together own the firm. They are supported by a team of seven investment professionals and a network of operating partners with more than 55 years of combined experience, as stated on the firm's website.

### How does Milestone Investisseurs source proprietary deal flow?

Milestone focuses on founder- and family-owned small and mid-cap companies in French-speaking Switzerland, France, Belgium, and Luxembourg. The firm's sourcing model relies on direct engagement with management teams and a network of experienced independent directors and entrepreneurs, rather than broad auctions, according to its own disclosures.

### Does Milestone Investisseurs participate in fund commitments or only direct deals?

Milestone Investisseurs only executes direct majority-control deals. The firm does not make fund commitments or minority growth investments. Each transaction is capitalized through a dedicated single-deal fund structure rather than a blind-pool commingled fund.

### What investment stages and enterprise-value bands does Milestone target?

The firm targets buyouts, management buy-ins, divestitures, spin-offs, and carve-outs in small and medium-sized enterprises with enterprise values of €30M to €300M. It invests €5M to €50M in equity per transaction and requires targets to have a minimum EBITDA of €5M.

### Which sectors does Milestone Investisseurs explicitly avoid or prioritize?

Milestone is a generalist but expresses particular expertise and interest in healthcare (services and manufacturing), business services, branded consumer goods, specialty distribution, personal services, energy/environment, information technology, and niche or advanced industrial sectors, per the firm's own investment-strategy page.

### What is Milestone Investisseurs's known posture on co-investments alongside external GPs?

Milestone takes majority positions and structures each deal as a standalone fund for its own group of international institutional and family backers. The firm does not describe a practice of participating as a minority co-investor alongside unrelated general partners.
