Background
Marcus Lorentz is a Managing Director at Prostar Capital and Head of its Sydney office. He joined the firm in March 2019 as a Principal, arriving from Natixis, where he was a Director in the Project Finance team. At Natixis he was mandated with building the bank's Australian business, acting as lead arranger across infrastructure sectors in the project-finance market. Prior to Natixis he spent more than four years as a Director at Crédit Agricole CIB, working across both the London and Sydney offices. Reporting at the time of his hire credited him with over 17 years of global infrastructure advisory experience.
At Prostar, Lorentz is responsible for deal structuring, execution, asset management, monitoring and reporting for the firm's investments. His expertise centers on structuring and executing investments in the clean-energy and decarbonization sectors, with a particular focus on midstream market opportunities across the Asia-Pacific region.
Educationally, Lorentz received his undergraduate degree in 1999 from the University of Canterbury (New Zealand) and a graduate degree in 2001 from the University of New South Wales (Built Environment).
Prostar Capital itself is a private investment firm founded in 2012, focused on the global energy supply chain and the transition to carbon neutrality. It manages over US$800 million in assets, and its partners have collectively originated and managed 18 infrastructure investments representing roughly US$4.0 billion of enterprise value and US$1.9 billion of equity invested.
Investment Thesis & Focus
- Invests in mid-market energy-infrastructure and energy-transition assets in OECD Asia-Pacific countries, not early-stage startups — the "angel / seed" label in the source stub does not match Prostar's actual mandate.
- Targets midstream assets "essential to the movement of energy from its source to its end-users" — gathering, processing, storage, transmission and distribution — located in strategic trading and logistics hubs.
- Seeks mid-sized companies/assets with enterprise valuations under ~US$1 billion that generate "definitive and sustainable cash flows" with growth potential.
- Positions the firm as "a responsible and sustainable investor in energy infrastructure, supporting rising global demand and energy resiliency in the transition to carbon neutrality."
- Sector emphasis on natural gas/midstream, renewables and hydrogen; takes a hands-on, operational approach to portfolio assets, applying technical and financial management to advance them.
Notable Investments
- Kyungnam Energy — South Korean city-gas distribution business; Prostar acquired 95%+ alongside co-investor BlackRock in 2017.
- Prostar Asia-Pacific Energy Infrastructure Fund I — the firm's first APAC-dedicated vehicle, targeting ~US$400m for energy-transition assets including natural gas, renewables and hydrogen projects in OECD markets including Australia.
- *(Firm-level track record: partners have collectively managed 18 infrastructure investments totaling ~US$4.0bn enterprise value; individual deal attribution to Lorentz is not publicly broken out.)*
