Description

Stonepeak Infrastructure Partners is a leading global private equity firm specializing in infrastructure investments, established in 2011 and headquartered in New York. The firm focuses on long-term investments in essential infrastructure assets across various sectors, including energy, transportation, digital infrastructure, and utilities. Stonepeak's investment philosophy centers on acquiring assets that exhibit stable cash flows, provide inflation linkage, and benefit from high barriers to entry, aiming to create value through operational improvements and strategic growth.

Stonepeak manages substantial capital, with its total assets under management exceeding $60 billion as of early 2024. This significant capital base enables the firm to undertake large-scale, complex transactions globally. Their investment strategy involves taking control or significant minority stakes in companies that provide critical services, often through long-term contracts. The firm's disciplined approach emphasizes due diligence and a deep understanding of the regulatory and operational landscapes of the infrastructure sector.

In February 2024, Stonepeak successfully closed its latest flagship fund, Stonepeak Infrastructure Fund V, at an impressive $33 billion, making it one of the largest infrastructure funds ever raised. This substantial fund underscores the firm's continued ability to attract significant institutional capital and its commitment to deploying large equity checks into high-quality infrastructure opportunities. Stonepeak typically commits equity ranging from several hundred million dollars to over a billion dollars per transaction, reflecting its focus on major infrastructure projects and companies that require substantial capital for development, expansion, or acquisition.
