About This Fund
Meridiam Infrastructure North America Fund III (MINA III) is a core infrastructure fund managed by Meridiam, a Paris-headquartered independent infrastructure investor and asset manager founded in 2005 by Thierry Déau. Meridiam manages over EUR 23 billion across more than 130 projects globally and is structured as a Benefit Corporation, uniquely aligning long-term financial returns with measurable social and environmental impact. The firm operates across the Americas, Europe, and Africa, with the MINA series representing its flagship North American infrastructure platform.
MINA III targets contracted, long-duration infrastructure assets across North America — primarily through public-private partnerships (P3) — the vehicle through which governments and private investors co-develop and operate critical public infrastructure under multi-decade concession agreements. The fund focuses on three core sectors: energy infrastructure (including low-carbon and energy transition assets), mobility infrastructure (express lanes, toll road concessions, and public transit), and social infrastructure (educational, judicial, and healthcare facilities). Investment holding periods typically span 20 to 35 years, aligned with concession terms and providing institutional LPs with stable, long-duration, contracted cash flows.
MINA III is the third vintage in Meridiam's flagship North America infrastructure series. The fund closed at approximately .41 billion with a 2017 vintage, following MINA II, which closed at approximately .05 billion in 2012–2013. MINA III's successor, MINA IV, closed in October 2025 at .8 billion — significantly exceeding its .7 billion target — reflecting the deepening institutional appetite for Meridiam's P3-focused infrastructure strategy in North America.
