## Questions

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

Co-Founders and Managing Partners David Scaysbrook and Rory Quinlan jointly lead the firm. Both spent over a decade at Macquarie Group's infrastructure division before launching Quinbrook in 2015. The duo maintains a flat partnership structure, with investment decisions made through the senior partnership group that includes regional heads in the US, UK, and Australia.

### How does Quinbrook source its projects?

Quinbrook principally originates its own deals through a dedicated in-house development team rather than through competitive auctions or broker-led processes. The firm identifies favorable grid interconnection points, secures land rights, and progresses projects through permitting and offtake contracting. This originate-to-operate model is designed to capture development margin and retain control over asset quality.

### Which investment stages does Quinbrook typically target?

Quinbrook invests across the full lifecycle of energy infrastructure assets. It commits capital at the greenfield development stage, funds construction, and holds operating assets long-term. The firm will also selectively acquire late-stage development or repowering opportunities where it can apply its in-house engineering and commercial capabilities.

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

Quinbrook primarily structures and leads its own investments. The firm has not publicly promoted a co-investment club or systematic co-underwriting model with peer GPs. However, its fund vehicles are designed to accommodate co-investment by large limited partners on a deal-by-deal basis, which is standard practice for infrastructure fund managers of its size.

### Which geographies does Quinbrook focus on?

Quinbrook concentrates exclusively on three core OECD markets: the United States, the United Kingdom, and Australia. This geographic triangulation reflects the partners' own Macquarie backgrounds, the availability of large-scale renewable resource potential, and the presence of liquid power markets and transparent regulatory frameworks.

### How does Quinbrook's strategy differ from generalist infrastructure funds that also invest in renewables?

Quinbrook is purely thematic, investing only in energy transition infrastructure. Unlike diversified infrastructure funds that allocate a percentage to renewables alongside airports, toll roads, and utilities, Quinbrook's sole mandate is the build-out of low-carbon power assets. Additionally, its internal development capabilities mean it regularly takes on construction and merchant power price risk that many generalist infrastructure investors are not resourced to underwrite.
