## Questions

### Who runs investment decisions at Quinbrook Infrastructure Partners?

David Scaysbrook and Rory Quinlan serve as co-founders and managing partners, leading the firm's investment committee. Both previously led Babcock & Brown's North American and Australian infrastructure activities before its collapse in 2009. The firm maintains a dedicated investment team across its offices, though specific composition is not publicly detailed.

### Does Quinbrook participate in fund commitments or only direct deals?

Quinbrook primarily makes direct infrastructure investments through its commingled funds, such as the Quinbrook Net Zero Power Fund, which closed at $3.6 billion in January 2025. The firm also engages in co-investments alongside institutional limited partners and structures separate accounts for certain clients, but it does not operate as a fund-of-funds.

### Which sectors does Quinbrook explicitly focus on?

Quinbrook focuses exclusively on energy transition infrastructure across three pillars: renewables (solar, wind, battery storage), power delivery (transmission and distribution), and industrial decarbonization (green hydrogen, carbon capture, sustainable fuels). The firm does not invest in fossil-fuel production, general real estate, or unconnected sectors.
