Unitil to Purchase Maine Natural Gas Company from Avangrid

HAMPTON, N.H., April 01, 2025 (GLOBE NEWSWIRE) -- Unitil Corporation (NYSE: UTL) () today announced that it has entered into a definitive agreement to acquire Maine Natural Gas Company (“Maine Natural”) from Avangrid Enterprises, Inc., for $86.0 million on a debt-free basis, subject to adjustment for closing working capital and transaction expenses. Upon closing of the transaction, which is expected to occur by the end of 2025, Maine Natural will become a wholly owned subsidiary of Unitil. The transaction is subject to approval by the Maine Public Utilities Commission.

Maine Natural Gas Company commenced operations in 1999 and serves approximately 6,300 residential and commercial natural gas customers in nine communities in the Greater Portland region of Maine, as well as the capital city of Augusta. Maine Natural’s gas system includes approximately 230 miles of distribution mains, providing opportunities for continued customer growth. Maine Natural is estimated to have approximately $69.0 million of rate base as of December 31, 2024. Customer growth over the most recent five-year period averaged 4.4% annually.

Maine Natural serves communities that are geographically contiguous with Unitil’s existing service areas in the Greater Portland region, an attractive and densely populated region of Maine. In combination with the Company’s most recent acquisition of Bangor Natural Gas Company, Unitil will serve communities representing over 40% of Maine’s total population. The transaction is expected to be earnings accretive over the long-term, supporting Unitil’s long-term earnings per share growth of 5% to 7%.

“Maine Natural Gas Company is highly complementary to our existing natural gas distribution operations in Maine,” said Thomas P. Meissner, Jr., Unitil’s Chairman and Chief Executive Officer. “Maine Natural Gas Company brings a dedicated team focused on providing safe, clean, reliable, and affordable energy to customers. We share their dedication to serving communities in Maine by providing responsive, high-quality service through locally-managed operations.”

Unitil has obtained committed debt financing from Scotiabank to fund the purchase price and is being advised in this transaction by Scotiabank and by the law firm of Dentons.
