Audio By Carbonatix

WASHINGTON--(BUSINESS WIRE)--Oct 2, 2025--

Meridiam is pleased to announce the successful close of MINA IV, its fourth-generation North America infrastructure fund, with commitments of more than $1.8 billion, above its $1.7bn-initial target and surpassing the previous fund, MINA III. This achievement reflects the robust interest and confidence of global investors in Meridiam’s differentiated long-term strategy and execution capabilities, especially in a complex market environment.

Meridiam’s successful fundraising comes at a pivotal moment for the firm, marking two decades of pioneering sustainable and resilient infrastructure globally since its founding in 2005.

MINA IV builds on Meridiam’s established expertise in delivering complex infrastructure projects and its tailored investment model focused on contracted infrastructure assets that offer long-term value creation and stable cash flows. MINA IV will focus on transformative infrastructure projects that deliver robust returns and measurable impact across energy, mobility, and essential services sectors.

The fund leverages Meridiam’s well-established positioning to access high-quality assets, including US express lanes, a segment where Meridiam has established a leading presence and deep expertise. In August Meridiam closed the SR400 Express Lanes P3 Project, one of the largest of its kind in the US with a total size of c.$11bn.

“We are deeply grateful for the trust and support of our investors,” said Thierry Déau, CEO and founder of Meridiam. “This successful fundraising reflects our ability to consistently deliver performance, with differentiated and resilient portfolios. It also reaffirms our commitment to shaping the future of infrastructure through innovation, resiliency, and long-term partnerships. With a strong pipeline of projects, we are well-positioned to deploy capital efficiently and drive sustainable growth.”
