Buy Plan / Sale Plan: These are also open market purchases/sales of shares, but in this case the transaction is part of a trading plan. Rule 10b5-1 allows insiders to setup a trading plan to buy/sell stocks over a certain period of time. Since the purchases/sales are predetermined, this protects the insiders from violating insider trading law.

Transaction was made pursuant to a contract, instruction or written plan for the purchase or sale of equity securities of the issuer that is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c).

F1	The original Form 4 filed on February 28, 2025 is amended to report the inadvertent omission of a transaction made pursuant to a Rule 10b5-1 trading plan established by the reporting person on September 16, 2024. As previously disclosed, Mr. Anderson has announced his intention to retire from his position as CEO of NW Holdings and NW Natural, effective April 1, 2025. At the time the 10b5-1 Plan was established, Mr. Anderson held more than 8 times his annual salary in NW Holdings' stock; an amount greater than required by the NW Holdings' stock ownership requirements. This trading arrangement allows Mr. Anderson to periodically sell a portion of his NW Holdings common stock to diversify his holdings in connection with his retirement.
