Antin Infrastructure Partners S.A. is a leading independent private equity firm focused exclusively on infrastructure investments. Founded in 2007 and headquartered in Paris, the firm operates globally with additional offices in London, New York, Singapore, Seoul, and Luxembourg. Antin's business model centers on raising and managing capital across three primary investment strategies: its Flagship Fund series (targeting large-cap infrastructure), Mid Cap Fund series, and NextGen Fund series (focusing on next-generation sustainable infrastructure). The firm targets controlling stakes in businesses across four key sectors: energy and environment, digital technology, transportation, and social infrastructure.
Antin generates revenue primarily through long-term contracted management fees based on fee-paying assets under management (AUM), which stood at approximately €22 billion out of a total AUM of over €33 billion in 2025. The firm also earns carried interest and investment income based on the performance and successful exits of its portfolio companies. Management fees from its Flagship funds constitute the vast majority of its revenue, supplemented by steady contributions from its Mid Cap and NextGen strategies. Geographically, Antin focuses its investments primarily in Europe and North America, leveraging its local presence to source proprietary deals. The firm's competitive position is underpinned by its pure-play focus on infrastructure, its value-added operational approach to portfolio companies, and its strong track record of capital deployment and value creation across economic cycles.
