Unitil (UTL) SVP & Gen. Counsel Carleton B. Simpson Receives Awards

What Happened
Carleton B. Simpson, Unitil Corporation's Senior Vice President, General Counsel & Secretary, received three equity awards on January 27, 2026 totaling 3,975 shares: two grants of 1,590 shares each and one contingent award of 795 shares. The awards were granted (transaction code A) at $0.00 per share (standard for equity awards) and will be valued at the market price on the applicable vesting or grant date. These are grants/awards (not purchases or sales) and reflect compensation rather than an open-market investment by the insider.

Context
Equity awards are a common form of executive compensation and typically vest over time or upon meeting performance goals. These grants do not represent an immediate cash transaction and do not, by themselves, signal insider buying or selling sentiment. The performance-based and contingent portions mean some shares may never be issued unless Unitil meets the specified goals.
