Investing across the capital structure to scale the critical infrastructure that powers, connects and sustains the modern economy
What we do
We partner with owners, operators, sponsors and management teams to support acquisitions and growth, navigate complexity and create value across markets globally. Our approach pairs flexible capital and capital structure insight with active asset management, value-add resources and deep sector expertise.
We approach every opportunity through the lens of the underlying business. Working as one integrated team, we provide everything from direct asset ownership and control equity to creative, balance-sheet-enhancing capital solutions.
Leveraging a deep, long-term capital base, we invest across equity, credit and asset partnerships with a flexible mandate. Our solutions-oriented approach, patient capital and meaningful scale allow us to support the infrastructure industry’s most significant transactions while structuring bespoke financing solutions for our companies and management teams.
We engage as a consistent, accountable partner—from first conversation through ownership—and we look to support management teams over the long term. Unconstrained by predetermined hold periods, we focus on patient value creation that adapts as business needs grow.
Our experience spans decades of investing across energy infrastructure, power, utilities, renewables and digital infrastructure. The convergence of power generation, grid transmission and surging data demand is fundamentally reshaping global infrastructure, creating a critical nexus our team is purpose-built to navigate.
Built on trust, transparency and a track record of delivering on our commitments, our long-standing global relationships across the infrastructure landscape enable us to connect people, assets and ideas to create differentiated value for our partners.
