Excess Returns in Electric Utility Mergers during Transition to Competition

Author

Abstract

A standard event methodology is used to evaluate recent electric utility mergers as the industry moves to competitive generation markets. Statistically significant effects were focused on the day before the announcement and the day of the announcement, and were fairly small, although statistically significant. Shareholders perceive very little merger benefits occurring in a highly competitive generation sector. Markets reacted more positively to the gas/electric mergers, indicating stockholder appreciation for opportunities for scope economies. U.S. acquirers suffered no significant wealth losses in mergers with British and Australian utilities. Copyright 2000 by Kluwer Academic Publishers
