Hydro One and Avista Mutually Agree to Terminate Merger Agreement

TORONTO and SPOKANE, WA, Jan. 23, 2019 /PRNewswire/ - Hydro One Limited ("Hydro One") (TSX: H) and Avista Corporation ("Avista") (NYSE: AVA) today announced that the companies have mutually agreed to terminate their previously announced merger agreement. This decision follows the recent orders by the Washington Utilities and Transportation Commission and the Idaho Public Utilities Commission which denied approval of the merger. After careful consideration and analysis of the likelihood of achieving a timely reversal of those orders, the Boards of Directors of Hydro One and Avista each individually determined that termination of the merger agreement is the best course of action for the companies and their respective shareholders.

Paul Dobson, acting President and CEO of Hydro One said, "Hydro One's Board, management and employees remain focused on delivering safe and reliable power, providing exceptional customer service and driving shareholder value. On behalf of Hydro One, I would like to thank the teams who have worked tirelessly on the proposed merger throughout this process."

Scott L. Morris, Chairman of the Board and CEO of Avista, said, "While disappointed with the outcome, I want to express our deepest gratitude to everyone who worked with us on this effort over the past 18 months. Avista is a strong, vibrant, and independent utility, and we look forward to building on our legacy of nearly 130 years by continuing to serve the best interests of our most important stakeholders—our valued customers, loyal employees, the communities we serve, and our shareholders."

As required by the merger agreement, Hydro One will pay Avista a US$103 million termination fee as a result of the termination of the merger agreement.
