UNITIL CORP 8-K

What Happened

• Unitil Corporation filed an 8-K on January 29, 2026, disclosing Amendment No. 1 to the Purchase and Sale Agreement (originally entered May 6, 2025) with Aquarion Water Authority and South Central Connecticut Regional Water Authority.
• The Amendment, dated January 23, 2026, changes the defined “Termination Date” in the Purchase Agreement from January 23, 2026 to February 23, 2026. The underlying agreement covers Unitil’s acquisition of Aquarion Water Company of Massachusetts, Aquarion Water Company of New Hampshire, and Abenaki Water Co., Inc.

Key Details

• Amendment date: January 23, 2026; 8-K filed January 29, 2026.
• Termination Date extended by one month: from January 23, 2026 → February 23, 2026.
• Parties: Unitil Corporation (buyer), Aquarion Water Authority (seller) and South Central Connecticut Regional Water Authority (limited party to certain sections).
• No other material changes to the Purchase Agreement; Unitil and its affiliates report no other material relationships with the seller or RWA.

Why It Matters

• The amendment keeps the pending acquisition on foot by extending the deadline to close the deal, giving the parties an additional month to satisfy closing conditions or complete the transaction.
• For investors, this affects the timing of when the Aquarion assets would become part of Unitil — but the Amendment does not change deal economics or other substantive terms disclosed previously.
• The filing notes that representations and warranties in the Amendment are contractual and made for the parties’ benefit; they should not be read as independent factual statements about Unitil’s condition.
