We help our existing clients create lasting impact

PRIVATE SECTOR CLIENTS

Investors and companies

Infrastructure investors need access to investment opportunities and must appraise those opportunities for value and risk. We use our extensive market knowledge, networks, models, database and advanced analytic techniques to assist investors. We identify opportunities, advise on strategy, and assist with commercial, market, regulatory and political due diligence. Once capital is committed, we assist investors in achieving value through shaping policy, developing compelling regulatory submissions, and providing expert evidence when disputes arise.

Strategy and proprietary deal flow

Projects and transactions

Regulation policy and litigation support

PUBLIC SECTOR CLIENTS

Governments, regulators and international agencies

We help governments and international organizations to create the policies, markets and regulatory frameworks that enable the finance and efficient provision of infrastructure and social services. Our wealth of international experience enables us to identify the gaps and bottlenecks that impede finance and service delivery. We work with our clients to develop master plans, investment pipelines, and new financing structures, often blending public and private finance. We ensure value for money in public expenditure through cost-benefit analysis, feasibility studies, and assessment of alternative finance and delivery options for projects. Where private finance and delivery is appropriate, we structure and manage transactions to bring in the best private partner. We assist regulators in setting tariffs and service standards, and in crafting pro-competitive access regimes. We provide governments with the frameworks they need to manage fiscal risk in infrastructure, and to maximize the finance available for development of essential services.
