Since Meridiam’s inception, our mission has always been to invest in and develop sustainable infrastructure that improves the quality of people’s lives.

Impact investing is founded on the intention to deliver positive environmental and societal benefits alongside a financial return. In 2022, we achieved B Corporation status, joining an elite group of some 6,500 companies worldwide that have a clear focus redefining the role of business to be a force for good.

“We have never considered an infrastructure project without thinking about what it can do for people. Our next step is to further professionalize impact investment, so it becomes even more sustainable for the long term.” says Thierry DéauFounding partner, Chief Executive Officer of Meridiam.

In 2022, we’ve invested over $4 billion in our three core sectors and created over 237,000 direct and indirect jobs, while also building on progress with investment and initiatives to reinforce many of our existing infrastructure projects and platforms.
