UNITIL CORP 8-K

What Happened
Unitil Corporation filed an 8-K on May 27, 2026 announcing Amendment No. 3 to its Purchase and Sale Agreement with Aquarion Water Authority (Seller) and South Central Connecticut Regional Water Authority (RWA). The amendment changes the agreement’s “Termination Date” to June 30, 2026. The original Purchase Agreement, dated May 6, 2025, contemplates Unitil acquiring Aquarion Water Company of Massachusetts, Aquarion Water Company of New Hampshire, and Abenaki Water Co., Inc.

Key Details

• Amendment No. 3 was entered on May 25, 2026 and replaces the prior termination date of May 25, 2026 with June 30, 2026.
• Prior extensions: Amendment No.1 (Jan 23, 2026) moved the date to Feb 23, 2026; Amendment No.2 (Feb 23, 2026) moved it to May 25, 2026.
• Parties: Unitil (buyer), Aquarion Water Authority (seller); RWA is a party only with respect to certain sections.
• Unitil states it and its affiliates have no other material relationships with the Seller or RWA beyond these agreements.

Why It Matters
This amendment extends the deadline for completing Unitil’s planned acquisition of several Aquarion water companies, giving the parties additional time to satisfy closing conditions or secure approvals. For investors, the change signals a timing delay rather than a change in transaction terms or counterparty—other substantive terms of the Purchase Agreement remain unchanged.
