Macquarie Asset Management has announced that its infrastructure fund, Macquarie Infrastructure Partners VI (MIP VI), has exercised an option to increase its equity stake in Diamond Infrastructure Solutions. The move raises MIP VI’s ownership from 40% to 49% in select U.S. Gulf Coast infrastructure assets owned by Dow Inc.
Diamond Infrastructure Solutions operates at five sites across Texas and Louisiana, providing services to Dow and other industrial customers. The company aims to improve operational efficiency and attract new customers as part of its business model.
“In the four months since the joint venture between MAM and Dow was established, Diamond has established itself as an independent company focused on delivering world class infrastructure services and has already attracted a number of new unaffiliated customers,” said Ben Way, Global Head of Macquarie Asset Management. “We are thrilled to have the opportunity to increase our investment in Diamond as it grows its presence as the premier chemical park operator in North America.”
Dow will receive total cash proceeds of about $3 billion from these transactions, including $2.4 billion related to the initial sale of a 40% equity stake.
