Nossaman Announcement

Nossaman congratulates the California High-Speed Rail Authority (Authority) on executing a Co Development Agreement (CDA) with Momentum Alliance Partners, a global consortium of high-speed rail, infrastructure and investment firms positioned to help finance and deliver future high-speed rail expansion projects through potential public-private partnership models and long-term infrastructure commercialization opportunities. Momentum Alliance Partners includes internationally recognized firms specializing in infrastructure investment, rail operations, engineering, systems integration and commercial development, including Plenary Americas, CDPQ Infra, Keolis, SNCF Voyageurs, Jacobs, Sener, SYSTRA, Setec, Arup and Steer. The agreement marks a significant step in the Authority’s effort to position California high-speed rail for commercially viable expansion into the state’s major population centers.

Authority CEO Ian Choudri said, “Over the past year, the Authority has taken significant steps to reposition California high-speed rail around a more commercially focused and delivery-oriented strategy designed to accelerate expansion into the state’s major population centers. This agreement reflects growing market confidence in that strategy and the long-term potential of California high-speed rail as a transformative investment in California’s future. As construction advances and we prepare to begin high-speed rail track installation this year, partnerships like this allow us to evaluate how private-sector expertise, financing and delivery models could help accelerate system expansion.”

Nossaman serves as lead outside counsel for the Authority. The Nossaman team for the CDA is led by Yukiko Kojima and includes Frank Liu and Kimberly Kamkar. Through Nossaman Consults, Brent Butzin serves as commercial and strategic advisor to the Authority and the executive leadership team for the implementation of the CDA.
