What Meridiam does

Meridiam SAS is a Paris-headquartered, AMF-regulated infrastructure investment and asset management firm (Société par Actions Simplifiée; AMF approval GP-14000003; founded 2005) that develops, structures, finances, and operates long-duration public infrastructure assets through Public-Private Partnerships (P3s) across Europe, North America, the Middle East, and Africa. Its core offering is a platform of regional and thematic investment funds — including Meridiam Infrastructure North America IV (which led the $3.8 billion upfront concession payment on the $12 billion SR-400 Express Lanes P3 in Georgia), the over-€2 billion European Infrastructure CV fund, and the Green Impact Growth Fund (€27M into iwell, €150M into Allego) — rather than a single unified product. Under its French Société à Mission governance and B Corp certification, Meridiam embeds ESG/SDG objectives into fund mandates and consortium leadership on 25-30+ year concessions spanning transportation (SR-400, I-77, Calcasieu River Bridge, Sepulveda Transit Corridor), water desalination (€4 billion Jordan Red Sea project serving 3 million people), renewable hydrogen, EV charging, battery storage, and digital infrastructure.

Meridiam monetizes through three principal streams: recurring management and performance fees on AMF-regulated infrastructure funds offered to qualified/professional investors only via Confidential Private Placement Memoranda; long-duration concession cash flows from availability payments, tolls, user fees, and offtake agreements on operating P3 assets; and investment principal and co-investment equity returns from Meridiam's own capital committed alongside fund investors in each project. Pricing and fees are not publicly disclosed, and no retail or secondary market exists for fund interests. Go-to-market is enterprise-field-sales and event-driven: direct relationship origination with sovereigns, municipal/state DOTs, and multilateral development institutions (World Bank, AfDB, EBRD, IFC) through high-level convenings such as the Africa Forward Summit and Mission 300 Private Sector Council. Capital partners include Samsung Life Insurance (20% shareholder since April 2023), GIC (lead buyer on the European CV), Invest-NL, Rabobank, and a broad European institutional LP base; operational consortia pair Meridiam with tier-one EPC and operating partners including Bechtel, SUEZ, ENGIE North America, and American Triple I.

Revenue model

1. Infrastructure fund management fees: Recurring management and performance fees earned on AMF-regulated infrastructure investment funds (e.g., the European infrastructure CV fund exceeding €2 billion). Investors are qualified/professional clients only; capital is locked-in for fund life with no secondary market.
2. Concession returns / asset ownership income: Long-duration (typically 25–30+ year) cash flows from operating P3 concession assets in transportation (e.g., SR-400 Express Lanes GA, I-77 NC, I-10 Calcasieu River Bridge), water desalination (Jordan Red Sea project), renewable hydrogen (Kaskade Germany), and EV charging (Allego). Revenue is generated through availability payments, tolls, user fees, and offtake agreements.
3. Investment principal and co-investment returns: Meridiam commits its own capital alongside fund investors in each project, generating equity returns and co-investment fees on successful project delivery.

Product overview

Meridiam SAS is a global infrastructure investment and asset management firm that develops, structures, finances, and operates long-term public infrastructure assets through public-private partnerships (P3s). Its offering is organized as a platform of distinct regional and thematic investment funds rather than a single unified product: Meridiam Infrastructure North America IV handles large-scale North American infrastructure deals (such as the $12 billion SR-400 Express Lanes concession in Georgia), the European Infrastructure CV Fund channels over €2 billion into European infrastructure assets (including the LA Sepulveda Transit Corridor and the Jordan Aqaba-Amman desalination project), and the Green Impact Growth Fund targets sustainability-themed investments such as battery storage. Together these fund vehicles form the company's core offering, with investment coverage spanning energy transition, sustainable mobility, water infrastructure, and digital connectivity.
