AI brief of an SEC Form 8-K · Unitil (UTL)

Unitil extends Aquarion acquisition deadline to June 30, 2026

Neutral Impact 3 of 5 m&a Written later

Unitil Corporation signed Amendment No. 3 on May 25, 2026, to its purchase agreement for Aquarion Water Authority's water utility subsidiaries. The amendment moves the agreement's termination date from May 25, 2026 to June 30, 2026, which is the third extension of that date. The filing does not describe other changes, so the deal's status and terms are otherwise unchanged.

Key points

  • Amendment No. 3 dated May 25, 2026 changes the Termination Date in Section 8.1(d) from May 25, 2026 to June 30, 2026.
  • The deal covers all outstanding shares of Aquarion Water Company of Massachusetts, Aquarion Water Company of New Hampshire, and Abenaki Water Co., Inc.
  • Prior amendments moved the date from January 23, 2026 to February 23, 2026, then to May 25, 2026.
  • Except for the termination date, the purchase agreement remains unchanged.
