Mayer Brown wins multiple Proximo “Deals of Year” Awards
Mayer Brown advised on three transactions honored by Proximo as 2025 “Deals of the Year.” The awards represent the premier benchmark for outstanding achievements in project, infrastructure, and energy finance across key industries in North America.
The winning transactions are:
Proximo North America Transport Deal of the Year 2025 - SR 400 Peach Partners
Led by Projects & Infrastructure partner Stephanie Wagner, the Mayer Brown team acted as sponsors' counsel to SR 400 Peach Partners, LLP — a consortium composed of Meridiam, Acciona, and ACS — in connection with the financial close of a public-private partnership for the design, construction, operation, maintenance, and tolling of the new SR 400 Express Lanes project north of Atlanta. Representing a total investment of roughly $11 billion, the project includes a nearly $3.9 billion USDOT TIFIA loan, the largest of its kind to date, as well as a $3.4 billion private activity bonds issuance, the largest ever for a US public-private partnership.
Proximo North America Rail Deal of the Year 2025 - Brightline West
In March 2025, Mayer Brown represented Morgan Stanley in connection with the issuance by Brightline West, a high-speed rail network connecting Las Vegas and Southern California, of $2.5 billion in private activity bonds to refinance existing debt and fund ongoing construction in a financing that incorporated innovative structuring to provide collateral security in a $3 billion Federal Railroad Administration grant. Subsequently in fourth quarter of 2025, we advised on the restructuring of outstanding private activity bonds through a series of tender and exchange offers. The Mayer Brown team was led by Banking & Finance partners David Narefsky and George Miller. (Brightline West, and its sister company Brightline Florida, are the first privately developed and operated passenger rail in the US in over a century, and the only privately developed and operated high speed passenger rail in the US, connecting among the most heavily travelled East and West Coast transportation corridors. Both projects are owned, developed, and operated by affiliates of Fortress Investment Group.)
Proximo North America LNG Deal of the Year 2025 - Port Arthur LNG 2
Led by Banking & Finance partners Paul Jorissen and George Miller, the Mayer Brown team represented Goldman Sachs & Co. LLC in relation to an equity investment in Port Arthur LNG Phase 2, a liquefied natural gas infrastructure development led by Sempra Infrastructure Partners. A consortium of investors spearheaded by Blackstone Credit & Insurance, which also comprised Goldman Sachs, KKR, and funds managed by Apollo, purchased a 49.9% minority equity stake in the project for approximately $7 billion.
