## Questions

### Who runs investment decisions at Menadiona?

Investment decisions sit with CEO Carlos Cosin and the board, now including Portobello Capital representatives after the 2024 majority acquisition. The firm does not employ a dedicated CIO or formal investment committee structure typical of standalone family offices.

### How does Menadiona source deals?

Deal flow originates from the firm's industrial network in specialty chemicals, life sciences, and manufacturing. Menadiona co-invests alongside external venture investors, as seen in the Roka Furadada Series A round with O Financial Club and Women Angels for Steam, rather than leading rounds independently.

### Does Menadiona accept outside capital?

Not directly. Menadiona is not an asset manager open to third-party commitments. External investors can co-invest alongside Menadiona in specific deals, and Portobello Capital holds the majority stake, but there is no open fund vehicle.

### Which sectors does Menadiona target for investment?

Investments follow the firm's operational expertise: pharmaceutical APIs and intermediates, performance chemicals for coatings and adhesives, and contract manufacturing technologies. The Roka Furadada investment extends this into advanced materials for sun protection.
