Investment Details
Dow has received an additional $540 million following Macquarie Asset Management's decision to increase its minority equity stake in Diamond Infrastructure Solutions from 40% to 49%. This transaction brings the total proceeds to approximately $3 billion.
Strategic Partnership
The increase in equity stake is part of a strategic partnership between Dow and a fund managed by Macquarie Asset Management, which led to the creation of Diamond Infrastructure Solutions. This company focuses on infrastructure assets across the U.S. Gulf Coast.
Operational Control and Services
Despite the increased stake by Macquarie, Dow maintains operational control as the majority owner of Diamond. The partnership aims to drive growth through a range of services across sectors such as energy, environment, infrastructure, and pipelines, serving over 70 existing and new customers.

Additionally, Diamond and Third Pillar Solar have agreed on exclusive access to Diamond's Texas reservoir system to explore the potential deployment of up to 500MW of floating solar projects.
