4 terms

Form 4/A regulatory

"This Form 4/A amends the Form 4 filed on July 13, 2026"

Form 4/A is an amended filing that corrects or updates an earlier Form 4, the mandatory report that insiders (like company executives, directors, or large shareholders) must file when their ownership stakes change. Think of it as an edited receipt showing who bought or sold stock and when; investors use it to track insider confidence, detect potential conflicts, and spot trading patterns that might signal future company prospects.

dividend reinvestment financial

"Includes shares acquired from dividend reinvestment"

Dividend reinvestment is when the money earned from a company's profit sharing, called dividends, is automatically used to buy more shares of that company instead of being received as cash. This process helps investors grow their holdings over time without extra effort, much like using earned interest to buy more of a savings account. It encourages long-term investment growth by continuously increasing the amount of shares owned.

compensation rate schedule financial

"received pursuant to the NorthWestern Energy Group, Inc. compensation rate schedule"

non-employee directors regulatory

"compensation rate schedule for non-employee directors"

Non-employee directors are board members who do not work for the company as salaried employees and usually do not hold day-to-day management roles. They act like outside referees or independent coaches, providing oversight, asking tough questions, and protecting shareholders’ interests; investors care because these directors help ensure management is accountable, reduce conflicts of interest, and influence decisions that affect company strategy and long-term value.
