The transaction valued at US$2.55 billion will result in Avangrid becoming a wholly owned subsidiary of Iberdrola.

Partner Chang-Do Gong, who is the Co-Head of the firm’s US M&A practice, led the transaction.

Gong said, “It was a privileged to have the opportunity to lead this complex transaction, and I look forward to continuing to advise Iberdrola to help bring the transaction to a successful closing.”
