Dow Inc. has finalized a strategic partnership with Macquarie Asset Management by selling a 40% equity interest in Diamond Infrastructure Solutions, a standalone infrastructure entity holding select U.S. Gulf Coast assets. The agreement marks a significant move in Dow’s ongoing strategy to unlock value from non-core assets and enhance its balance sheet.

The equity stake was acquired by a fund managed by Macquarie Asset Management, a global leader in infrastructure and energy asset investment. Dow received initial cash proceeds of approximately $2.4 billion. Under the agreement, Macquarie has the option to increase its ownership to 49% within six months of the transaction's closing. If exercised, Dow would receive an additional $600 million, bringing total proceeds to roughly $3 billion in 2025.

"This growth-focused transaction to create a new infrastructure business entity represents a strategic partnership between Dow and Macquarie Asset Management that has been several years in the making," said Dow Chair and CEO Jim Fitterling. "With key assets strategically placed across the U.S. Gulf Coast, Diamond Infrastructure Solutions will provide safe and reliable operations for its existing customers while focusing on customer growth."

Diamond Infrastructure Solutions was established by Dow in 2023 and formally announced in December 2024. The company’s formation reflects Dow’s aim to drive operational efficiency and attract new customers by dedicating resources and leadership to infrastructure-specific operations. Since its launch, Diamond’s leadership team has been advancing a targeted growth strategy, with priorities including safety, workforce alignment and active outreach to new customers.

Despite the minority stake sale, Dow will retain majority ownership and control of Diamond to ensure the continued safety and reliability of its Gulf Coast operations. The company views the collaboration with Macquarie as a long-term opportunity to drive profitable growth and deliver value for both partners.

The partnership with Macquarie is consistent with Dow’s broader corporate strategy to streamline its global asset portfolio by divesting non-product producing operations. The company expects the deal to contribute positively to both Dow’s and Macquarie’s financial performance in the years ahead.

Dow’s collaboration with Macquarie further positions Diamond Infrastructure Solutions as a key player in the energy and infrastructure sector, supporting operational excellence and long-term customer partnerships along the U.S. Gulf Coast.
