Re:	Legal Opinion Regarding Validity of Securities Offered

Members of the Board:

We have acted as special counsel for Glacier Bancorp, Inc., a Montana corporation (“Glacier”), in connection with the registration under the Securities Act of 1933, as amended (the “Act”), of 1,600,000 shares of Glacier common stock, $0.01 par value per share (the “Shares”), authorized for issuance under the Glacier Bancorp, Inc. 2025 Stock Incentive Plan (the “2025 Equity Plan”) that was approved by the Company’s shareholders on April 30, 2025.

In connection with the Shares that will be issued under the 2025 Equity Plan, we have examined the following: (i) the 2025 Equity Plan; (ii) the Registration Statement on Form S-8 to be filed by Glacier with the Securities and Exchange Commission (the “Registration Statement”) (iii) resolutions adopted by the Board of Directors of Glacier relating to the authorization and approval of the 2025 Equity Plan and the registration of the Shares under the Registration Statement; and (iv) such other documents as we have deemed necessary to form the opinion expressed below. We have assumed that the documents reviewed and relied upon in giving the opinion expressed below are true and correct copies of the documents and the signatures on such documents are genuine. As to various questions of fact material to such opinion, where relevant facts were not independently established, we have relied upon statements of officers of Glacier or representations of Glacier contained in the 2025 Equity Plan. We have assumed, without independent investigation or review, the accuracy and completeness of the facts and representations and warranties contained in the documents listed above or otherwise made known to us.

Our opinion assumes that the Shares are issued in accordance with the terms of the 2025 Equity Plan after the Registration Statement has become effective under the Act.

Based upon and relying solely upon the foregoing, and subject to the exceptions and limitations set forth herein, it is our opinion that, under existing law, the Shares, or any portion thereof, when issued pursuant to and in accordance with the 2025 Equity Plan, after the Registration Statement has become effective under the Act, will be validly issued under the laws of the State of Montana and will be fully paid and non-assessable.
