Basalt Infrastructure Partners

Investment decisions are led by the senior partnership, with Rob Gregor and Steven Lowry as Senior Partners in London and John Hanna and David Greenblatt as Managing Partners in the New York office. The firm's flat partnership structure means major commitments require consensus among the senior team.

Basalt operates as an independent infrastructure fund manager, not a family office. It raises capital from institutional limited partners — pensions, insurers, and sovereign funds — and deploys it through closed-end commingled funds focused on mid-market infrastructure in Europe and North America.

Basalt emphasizes a proprietary, relationship-driven origination model aimed at founder-owned and family-held mid-market infrastructure assets. By maintaining senior operating partners with deep industry networks and avoiding reliance on broad auctions, the firm targets deals it believes carry less competitive tension on entry pricing.

Basalt invests directly into portfolio companies, typically taking control or significant minority stakes. It does not operate as a fund-of-funds; all capital is deployed through its own commingled vehicles, with the firm acting as the lead equity sponsor on each transaction.

Basalt focuses on power generation, regulated and contracted utilities, transportation infrastructure, and digital infrastructure (fiber, towers, data distribution). The geographic mandate is transatlantic — North America (US and Canada) and Europe (UK, Germany, Nordics, Italy, and others) — with occasional investments in Australia and New Zealand.

Basalt targets mid-market infrastructure equity checks, generally ranging from $50 million to $300 million per deal. The firm may invest smaller amounts in bolt-on acquisitions for existing platforms, but its strategy is built around assets that are too small for mega-funds and too operationally intensive for passive financial buyers.

Basalt applies mandatory sustainability pillars across all portfolio companies: climate resilience, environmental protection, human capital, and governance. Each investment receives a bespoke set of responsible-investment KPIs based on a materiality assessment. The firm publicly reports its ESG framework on its website, though it does not publish a standalone annual impact report as of early 2026.
