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. Together, these agreements streamline the acquisition scope, secure financing, and stabilize post-close operations.
