Analysis
Macquarie Asset Management has expanded its ownership in Diamond Infrastructure Solutions to 49 percent through Macquarie Infrastructure Partners VI (MIP VI). The latest transaction adds an additional 9 percent stake in Dow’s U.S. Gulf Coast assets, bringing total proceeds for Dow to $3.0 billion, including $2.4 billion from the original 40 percent sale earlier in 2025.
Diamond Infrastructure Solutions operates five major industrial sites across Texas and Louisiana, providing infrastructure services such as power, water, and logistics support to both Dow and third-party tenants. The platform is designed to deliver efficiency, safety, and reliability, while positioning itself as a leading chemical park operator in North America.
Since its launch earlier in 2025, Diamond has signed new agreements with unaffiliated customers, demonstrating the strength of its independent model. With Macquarie’s increased stake, the business is expected to accelerate growth and broaden its tenant base across the Gulf Coast.
The deal underlines Macquarie Asset Management’s long-term commitment to essential industrial and energy infrastructure. Over the past two decades, Macquarie has invested more than $26 billion in 60 portfolio companies across the Americas, focusing on regulated utilities, industrial parks, and energy transition assets.
Similar transactions highlight growing investor appetite for large-scale industrial infrastructure. BlackRock’s Global Infrastructure Partners (GIP) acquired a stake in BASF’s Antwerp chemical complex, enhancing access for third-party users. Brookfield Infrastructure has expanded its midstream energy portfolio with multi-billion-dollar acquisitions of North American pipelines and export terminals. EQT Infrastructure entered the specialty industrial space through European logistics and energy transition hubs, while KKR has expanded its U.S. infrastructure portfolio with investments in energy storage and industrial service platforms.
These transactions reflect a broader trend of global funds targeting resilient industrial infrastructure with stable cash flows and long-term growth potential. By raising its stake in Diamond Infrastructure Solutions to 49 percent, Macquarie strengthens its position in the Gulf Coast market and demonstrates its ability to align fundraising success with strategic deployment in high-value industrial assets.
