ICG, the global alternative asset manager, today announces the expansion of its global infrastructure platform with the launch of a European infrastructure debt strategy (“the Strategy”). The Strategy will provide flexible financing solutions to infrastructure transactions, projects and businesses across Europe, focusing on core/core+ infrastructure sectors underpinned by long-term structural growth trends. Augustin Segard and Grégoire Castres Saint Martin have been appointed to establish and lead the Strategy.
Augustin joins ICG in London from Schroders Capital, where he most recently served as Head of Junior Infrastructure Debt and led the successful “JULIE” fund series, investing across the credit spectrum and deploying significant capital into European infrastructure assets. Prior to this, he held roles at AXA Investment Managers and InfraRed Capital Partners. Grégoire joins ICG in Paris from Antin Infrastructure Partners, where he was most recently Managing Director within the firm’s financing team and where he built a strong expertise in structuring complex and innovative financings across the capital structure. He previously worked in infrastructure financing and advisory at BNP Paribas.
The launch reflects sustained growth in investor demand for infrastructure debt, driven by institutional appetite for essential-asset exposure and the long-term capital required to finance the energy transition, digitalisation and broader infrastructure investment. The Strategy will focus on the sub-investment grade segment of the market, an area that remains underserved and where ICG sees a compelling opportunity to provide flexible, higher-yielding capital solutions.
The Strategy will leverage ICG’s long-standing credit expertise, developed across a suite of strategies including Senior Debt Partners, the firm’s flagship direct lending fund series, which closed its fifth vintage at c.€15.2bn in 2024 and has established a leading position in the European direct lending market. The Strategy will also complement existing capabilities within ICG’s established infrastructure platform, which comprises dedicated European and Asia-Pacific teams. Both teams invest across the capital structure to provide growth capital to mid-market businesses, with the European team recently raising €3.15bn for its second fund vintage.
Benoît Durteste, CIO and CEO of ICG, commented:
The launch of our infrastructure debt strategy is a natural extension of our platform and reflects our ability to evolve in response to investor demand. Having built a market-leading infrastructure business, we are excited to expand into debt, drawing on ICG’s credit heritage and expertise. Augustin and Grégoire are highly respected investors with deep sector knowledge, and we are delighted to welcome them to ICG.
