Unitil Closes Aquarion NH and Abenaki Purchase, Secures $136 Million Credit and Transition Services

Unitil narrowed its Aquarion transaction to New Hampshire and Abenaki operations via a fourth amendment to the purchase agreement, then closed the deal on June 30, 2026 for $42.1 million in cash plus about $0.6 million for working capital and reimbursable capex. To support funding, Unitil entered an amended and restated credit agreement with Bank of Nova Scotia, providing up to $136 million across two tranches and drew $42.7 million at closing. The company also signed a transition services agreement with Aquarion Water Authority and Eversource Energy for up to 60 months to ensure operational continuity.
