PROXY STATEMENT		PROSPECTUS OF
OF TREASURE STATE BANK		GLACIER BANCORP, INC.

MERGER PROPOSED – YOUR VOTE IS VERY IMPORTANT

Dear Treasure State Bank Shareholders:

As you may know, the boards of directors of Treasure State Bank (“TSB”) and Glacier Bancorp, Inc. (“Glacier”) have agreed on a merger of TSB with and into Glacier Bank, Glacier’s subsidiary, subject to approval of TSB shareholders.

Under the terms of the Agreement and Plan of Merger, dated April 20, 2016, Glacier will issue to TSB’s shareholders a combination of shares of Glacier common stock and a cash payment, with each portion of the merger consideration being subject to adjustment as provided in the merger agreement and described in the attached proxy statement/prospectus.

Under the merger agreement, each outstanding share of TSB common stock will be exchanged for a “unit” comprised of a number of shares of Glacier common stock (0.2030 shares) and an amount of cash ($1.9570), each determined and subject to adjustment in accordance with the merger agreement. The stock portion of each unit is subject to adjustment in the event that the average closing price for Glacier common stock prior to closing, calculated in accordance with the merger agreement, is less than $19.00 (or less than $19.99 if Glacier’s stock price has underperformed the KBW Regional Banking Index by more than 10 percent), or more than $27.05, in order to avoid termination of the merger agreement. The cash portion of each unit will be reduced on a pro rata basis to the extent TSB’s capital prior to the closing of the merger, calculated in accordance with the merger agreement, is less than an amount equal to $9,575,557. If TSB’s capital prior to closing of the merger is greater than the minimum amount required, TSB will, upon written notice to Glacier and effective prior to the closing of the merger, declare and pay a special distribution in the amount of such excess, subject to certain possible tax-related limitations. For purposes of illustration only, as of June 7, 2016, TSB’s closing capital would have been $9,766,007, and TSB would have been entitled to distribute approximately $190,450 in cash to its shareholders prior to closing.

Assuming for purposes of illustration only that (i) there is no increase or reduction of the cash portion of each unit, and (ii) the average closing price for Glacier common stock is $27.44, which was the closing price of Glacier common stock on June 7, 2016, for each of your shares of TSB common stock, you will receive consideration with an estimated current value of $7.4482, consisting of a combination of $1.9570 in cash and Glacier common stock valued at $5.4912. Because the Glacier closing price on June 7, 2016 was above $27.05, this example assumes an adjustment of the stock portion of each unit as described above. The actual Glacier average closing price will not be determined until 10 days prior to the closing of the merger, and thus we cannot predict whether such average closing price will be above or below $27.05. TSB common stock is quoted on the over-the-counter markets (“OTC Markets”) via the OTC Pink marketplace (“OTC Pink”) but is not actively traded. According to the OTC Pink, the most recent transaction in TSB common stock occurring prior to the announcement of the proposed merger was on February 29, 2016 at a price of $5.00 per share. Assuming the exchange of all outstanding TSB common stock for stock and cash in accordance with the merger agreement, TSB shareholders will own approximately 0.5% of Glacier’s outstanding common stock following the merger.

We will hold a special shareholders’ meeting to vote on the merger agreement. The special meeting of the shareholders of TSB will be held on July 20, 2016, at 8:00 a.m. local time, at 3660 Mullan Road, Missoula, Montana . Whether or not you plan to attend the special meeting, please take the time to vote by completing and mailing the enclosed form of proxy.

On behalf of the board of directors of TSB, I recommend that you vote FOR approval of the merger agreement.

QUESTIONS AND ANSWERS

Why am I receiving these materials?

We are sending you these materials to help you decide how to vote your shares of Treasure State Bank (“TSB”) common stock with respect to the proposed merger with Glacier Bank, a wholly owned subsidiary of Glacier Bancorp, Inc. (“Glacier”). The merger cannot be completed unless TSB receives the affirmative vote of the holders of at least two-thirds (66 2/3%) of the outstanding shares of TSB’s common stock. TSB is holding a special meeting of shareholders to vote on the proposals necessary to complete the merger. See “The Merger.” Information about the special meeting is contained in this document. See “TSB Special Shareholders Meeting.”

This document is both a proxy statement of TSB and a prospectus of Glacier. It is a proxy statement because the board of directors of TSB (the “TSB Board”) is soliciting proxies from TSB shareholders in connection with voting on the merger. It is a prospectus because Glacier will issue shares of its common stock in exchange for shares of TSB common stock as part of the consideration to be paid in the merger.

What will TSB shareholders receive in the merger?

Under the terms of the merger agreement, each share of TSB common stock will be exchanged for a “unit” comprised of 0.2030 shares of Glacier stock and $1.9570 in cash. Both the stock portion and the cash portion of each unit are subject to the adjustments described below.

The stock portion of each unit may be adjusted in certain circumstances based on whether Glacier common stock is trading either higher or lower than prices specified in the merger agreement immediately prior to the closing of the merger, in order to avoid termination of the merger agreement.

The cash portion of each unit will be subject to adjustment depending on the “TSB Closing Capital,” as defined in the merger agreement, immediately prior to the closing of the merger. The merger agreement provides that, if the adjusted TSB Closing Capital is less than $9,575,557, the cash portion of each unit will be reduced on a pro rata basis by the amount of such deficiency. For purposes of calculating “TSB Closing Capital,” to the extent TSB’s final transaction-related expenses exceed or are less than $1,100,000, the difference, on an after-tax basis, will be reflected as a pro forma adjustment to TSB’s actual capital.

If the adjusted TSB Closing Capital is greater than $9,575,557, TSB will, upon written notice to Glacier and effective prior to the closing of the merger, declare and pay a special distribution in the amount of such excess, subject to certain possible tax-related limitations.

On June 7, 2016, the closing price of Glacier’s common stock was $27.44 per share. If the average closing price (determined over a 20 trading day period prior to the closing of the merger, calculated 10 days prior to the closing) of Glacier’s common stock exceeds $27.05, Glacier may terminate the merger agreement, unless TSB elects to accept a reduction on a per-share basis in the number of shares of Glacier common stock to be issued in the merger. Based on the assumption that the average closing price is the price as of June 7, 2016, which was $27.44 per share, if TSB were to elect to accept such a reduction, the number of shares of Glacier stock to be issued for each TSB share in the merger would be reduced from 0.2030 to 0.2001.

Conversely, if the average closing price is (i) below $19.99 but not less than $19.00 and the price of Glacier common stock has underperformed KBW Regional Banking Index by more than 10%, or (ii) is below $19.00, TSB may terminate the merger agreement, unless Glacier elects to increase on a per-share basis the number of shares of Glacier common stock or cash to be issued in the merger. See “The Merger – Termination of the Merger Agreement.”

By voting to approve the merger agreement, TSB shareholders will give the TSB Board the authority to elect, with the advice of TSB’s legal counsel and its financial advisor, to cause TSB to accept a reduction in the number of shares of Glacier common stock to be issued in the merger, if the Glacier average closing price exceeds $27.05 as described above. See “The Merger – Termination of the Merger Agreement.”

What will I receive in the merger?

Under the merger agreement, each outstanding share of TSB common stock will be exchanged for a “unit” comprised of Glacier common stock (0.2030 shares) and cash ($1.9570). Each of the stock and cash portions of each unit will be subject to adjustment as described above.

Assuming for purposes of illustration only that (i) there is no increase or reduction of the cash portion of the merger consideration, and (ii) the average closing price for Glacier common stock is $27.44 (which was the closing price for Glacier common stock on June 7, 2016), each share of TSB common stock would be exchanged for consideration with a total value equal to $7.4482, consisting of $1.9570 in cash and 0.2001 shares of Glacier common stock valued based on the average closing price above. The number of Glacier shares issued for each TSB share in this example reflects a reduction from 0.2030 shares to 0.2001 shares because the June 7, 2016 Glacier closing price was above $27.05 and assumes that Glacier requires, and TSB accepts, a lower exchange ratio as described above. The actual Glacier average closing price will not be determined until 10 days prior to the closing of the merger, and it cannot be predicted whether such average closing price will be above or below $27.05. See “The Merger – Merger Consideration.”

When will the merger occur?

We presently expect to complete the merger during the third quarter of 2016. The merger will occur after the approval of the merger agreement by the affirmative vote of holders of at least two-thirds (66 2/3%) of the shares of TSB common stock, after the merger has received regulatory approval and following the satisfaction or waiver of the other conditions to the merger described in the merger agreement. Glacier and TSB are working toward completing the merger by August 31, 2016. If the merger does not occur for any reason by November 30, 2016, either Glacier or TSB may unilaterally terminate the merger agreement.

How soon after the merger is completed can I expect to receive my merger consideration?

Glacier will work with its exchange agent to distribute consideration payable in the merger as promptly as practicable following the completion of the merger.

Will the shares of Glacier common stock that I receive in the merger be freely transferable?

The Glacier common stock issued in the merger will be transferable free of restrictions under federal and state securities laws.

When and where will the special meeting take place?

TSB will hold a special meeting of its shareholders on Wednesday, July 20, 2016, at 8:00 a.m. local time, at 3660 Mullan Road, Missoula, Montana.

Who may vote at the special meeting?

The TSB Board has set June 6, 2016, as the record date for the special meeting. If you were the owner of TSB common stock at the close of business on June 6, 2016, you may vote at the special meeting.

What vote is required to approve the merger agreement?

Approval of the merger agreement requires the affirmative vote of the holders of at least two-thirds (66 2/3%) of the shares of TSB’s outstanding common stock. As described in this proxy statement, the directors of TSB have agreed to vote the shares they own in favor of the merger agreement. Such persons own approximately 19.37% of outstanding TSB common stock. See “TSB Special Shareholders’ Meeting” and “The Merger – Voting Agreement.”

What vote is required to approve the adjournment of the special meeting, if necessary or appropriate?

The proposal to adjourn the TSB special meeting, if necessary or appropriate, including adjournments to solicit additional proxies in favor of the merger, will be approved if the votes cast in favor of the proposal exceed the votes against the proposal, assuming a quorum is present. If less than a quorum is represented at the special meeting, a majority of shares so represented may adjourn the special meeting.

How do I vote?

To vote, please indicate on the enclosed proxy card how you want to vote and then sign, date, and mail your proxy card in the enclosed envelope as soon as possible so that your shares will be represented at the special meeting.

Can I change my vote after I have mailed my signed proxy card?

Yes. You may change your vote at any time before your proxy is voted at the special meeting. If your shares of TSB common stock are held in your own name, you may change your vote as follows:

•

You may send a written notice to the Secretary of TSB stating that you would like to revoke your proxy and provide new instructions on how to vote;

•

You may complete and submit a later-dated proxy card; or

•

You may attend the meeting and vote in person. If you intend to vote in person and your shares of TSB common stock are held by a broker, you should contact your broker for instructions.

If you choose either the first or second method above, you must submit your notice of revocation or your new proxy card to TSB’s Secretary prior to the vote at the special meeting.

What happens if I return my proxy but do not indicate how to vote my shares?

If you sign and return your proxy card, but do not provide instructions on how to vote your shares of TSB common stock, your shares of TSB common stock will be voted “FOR” approval of the merger agreement at the special meeting.

How does the TSB board of directors recommend that I vote?

The TSB Board recommends that TSB shareholders vote “FOR” the proposals described in this proxy statement/prospectus, including in favor of the merger agreement.

What do I need to do now?

We encourage you to read this proxy statement/prospectus in its entirety. Important information is presented in greater detail elsewhere in this document, and documents governing the merger are attached as appendices to this proxy statement/prospectus. In addition, much of the business and financial information about Glacier that may be important to you is incorporated by reference into this document from documents separately filed by Glacier with the Securities and Exchange Commission (“SEC”). This means that important disclosure obligations to you are satisfied by referring you to one or more documents separately filed with the SEC.

Following review of this proxy statement/prospectus, please complete, sign, and date the enclosed proxy card and return it in the enclosed envelope as soon as possible so that your shares of TSB common stock can be voted at TSB’s special meeting of shareholders.

If my shares are held in “street name” by a broker, bank or other nominee, will my broker or nominee vote my shares for me?

No. If your shares are held in “street name” in a stock brokerage account or by a bank or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank or broker. Please note that you may not vote shares held in street name by returning a proxy card directly to TSB or by voting in person at the shareholder meeting unless you provide a “legal proxy,” which you must obtain from your broker, bank or other nominee.

Brokers, banks and other nominees are not allowed to exercise their voting discretion on matters that are determined to be “non-routine” without specific instructions from you as the beneficial owner. If you are a TSB shareholder who owns shares in “street name” and you do not instruct your broker, bank or other nominee on how to vote your shares, your broker, bank or other nominee may not vote your shares on the proposal to approve the merger agreement, which will have the same effect as a vote “AGAINST” the proposal.

Should I send in my common stock certificates now?

No . Please do not send your TSB common stock certificates with your proxy card. You will receive written instructions from Glacier’s exchange agent promptly following the closing of the merger on how to exchange your TSB common stock certificates for the merger consideration.

What risks should I consider?

You should review carefully our discussion under “Risk Factors.” You should also review the factors considered by the TSB Board in approving the merger agreement. See “Background of and Reasons for the Merger.”

What are the tax consequences of the merger to me?

Glacier and TSB expect to report the merger of TSB with and into Glacier Bank as a tax-free reorganization for United States federal income tax purposes under Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code). In connection with the filing of the registration statement of which this document is a part, Garlington, Lohn & Robinson PLLP, special tax counsel to Glacier, has delivered an opinion to Glacier that the merger will qualify as a reorganization under Section 368(a).

In a tax-free reorganization, a shareholder who exchanges the shareholder’s shares of common stock in an acquired company for shares of common stock in an acquiring company, plus cash, must generally recognize gain (but not loss) on the exchange in an amount equal to the lesser of (1) the amount of gain realized (i.e., the excess of the sum of the fair market value of the shares of acquiring company common stock(including any fractional shares) and cash received pursuant to the merger (excluding any cash received in lieu of fractional shares) over the shareholder’s adjusted tax basis in the shareholder’s shares of acquired company common stock surrendered pursuant to the merger), or (2) the amount of cash (excluding any cash received in lieu of fractional shares) received pursuant to the merger.

For a detailed discussion of the material United States federal income tax consequences of the merger, see “The Merger – Material Federal Income Tax Consequences of the Merger.”

We urge you to consult your tax advisor to fully understand the tax consequences to you of the merger. Tax matters are very complicated and in many cases the tax consequences of the merger will depend upon your particular facts and circumstances.

Do I have appraisal or dissenters’ rights?

Yes. TSB shareholders are entitled to dissenters’ rights under Sections 35-1-826 through 35-1-839 of the Montana Business Corporation Act. If you vote against the merger agreement and take certain other actions required by Montana law to exercise these rights, you will be entitled to have your shares of TSB common stock purchased at “fair value,” as determined in accordance with Montana law. Please read the section entitled “The Merger – Dissenters’ Rights of Appraisal” for additional information.

The Merger

The merger agreement provides for the merger of TSB with and into Glacier Bank. In the merger, your shares of TSB common stock, if you do not dissent, will be exchanged for a combination of shares of Glacier common stock and cash. After the merger, you will no longer own shares of TSB. For additional information, see the discussion under the heading “The Merger” below.

The merger agreement is attached as Appendix A to this proxy statement/prospectus. We encourage you to read the merger agreement in its entirety.

In the merger, Glacier will issue shares of its common stock and pay cash for all shares of TSB common stock outstanding as of the date of the closing of the merger.

Under the merger agreement, each outstanding share of TSB will be exchanged for a “unit” comprised of Glacier common stock and cash, as follows:

•

Stock Portion : 0.2030 Glacier shares, subject to adjustment as follows: If the average closing price of Glacier stock calculated in accordance with the merger agreement exceeds $27.05, Glacier may elect to terminate the merger agreement, unless TSB elects to accept a decrease in the number of Glacier shares to be issued on a per-share basis, in order to avoid termination of the merger agreement. Conversely, if the average closing price is (i) below $19.99 but not less than $19.00 and the price of Glacier common stock has underperformed the KBW Regional Banking Index by more than 10%, or (ii) is below $19.00, TSB may elect to terminate the merger agreement, unless Glacier elects to increase the number of shares or amount of cash to be issued on a per-share basis, in order to avoid termination of the merger agreement. Glacier will not issue fractional shares, and will pay cash in lieu of such fractional shares, as described under “The Merger – Fractional Shares.”

•

Cash Portion : $1.9570 in cash, subject to adjustment as follows: If the adjusted “TSB Closing Capital” is less than $9,575,557, the cash portion of each unit will be reduced on a pro rata basis based on the amount of such deficit. The “TSB Closing Capital” is specifically defined in the merger agreement and is equal to an amount, estimated as of the closing date of the merger, equal to TSB’s capital stock, surplus and retained earnings determined in accordance with generally accepted accounting principles (“GAAP”) on a consolidated basis, net of goodwill and other intangible assets, and calculated in the same manner in which TSB’s consolidated tangible equity capital at December 31, 2015 was calculated, after giving effect to adjustments, calculated in accordance with GAAP, for accumulated other comprehensive income or loss as reported in TSB’s balance sheet.

For purposes of calculating “TSB Closing Capital,” to the extent TSB’s final transaction-related expenses exceed or are less than $1,100,000, the difference, on an after-tax basis, will be reflected as a pro forma adjustment to TSB’s actual capital. See “The Merger – Merger Consideration – Cash Portion of Merger Consideration.”

The actual amount of cash to be paid cannot be determined until shortly before the effective date of the merger. Accordingly, the actual amount of cash that you will receive for each of your shares of TSB common stock, if you do not dissent, will not be determined until shortly before the closing of the merger. See “The Merger – Merger Consideration.”

If the TSB Closing Capital is greater than $9,575,557, TSB will, upon written notice to Glacier and effective prior to the closing of the merger, declare and pay a special distribution in the amount of such excess. The amount of such special distribution may be limited, however, to the extent necessary to cause the merger to qualify as a tax-free reorganization within the meaning of applicable provisions of the Internal Revenue Code.

Recommendation of TSB Board of Directors

The TSB Board unanimously recommends that holders of TSB common stock vote “FOR” the proposal to approve the merger agreement.

For further discussion of TSB’s reasons for the merger and the recommendations of the TSB Board, see “Background of and Reasons for the Merger – Recommendation of the TSB Board of Directors.”

(“Davidson”) has served as financial advisor to TSB in connection with the merger and has given an opinion to the TSB Board that, as of April 20, 2016, the consideration that TSB’s shareholders will receive for their shares of TSB common stock in the merger is fair, from a financial point of view, to TSB shareholders.

A copy of the opinion delivered by Davidson is attached to this document as Appendix C. You should read the opinion carefully to understand the assumptions made, matters considered and limitations of the review undertaken by Davidson in providing its opinion.

The opinion is addressed to the TSB Board and is directed only to the fairness of the per-share consideration to the holders of TSB’s common stock from a financial point of view. It does not address the underlying business decision of TSB to engage in the merger or any other aspect of the merger and is not a recommendation as to how any TSB shareholder should vote with respect to the merger.

For further information, see “Background of and Reasons for the Merger – Opinion of Financial Advisor to TSB.”

Interests of TSB Directors and Executive Officers in the Merger

When you consider the unanimous recommendation of the TSB Board that TSB’s shareholders approve the merger agreement, you should be aware that certain members of TSB management have interests in the merger that are different from, or in addition to, their interests as TSB shareholders. These

interests arise out of, among other things, voting and non-competition agreements entered into by directors of TSB; change-in-control benefits payable to Mr. James Salisbury, Ms. Anne Robinson and Mr. Jason Erickson, in accordance with existing employment or change-in-control agreements with TSB; and provisions in the merger agreement relating to indemnification of TSB directors. For a description of the interests of TSB’s directors and executive officers in the merger, see “The Merger – Interests of Certain Persons in the Merger.”

The TSB Board was aware of these interests and took them into account in its decision to approve the merger agreement.

TSB Shareholders Dissenters’ Rights

Under Montana law, TSB shareholders have the right to dissent from the merger and receive cash for the “fair value” of their shares of TSB common stock. A shareholder electing to dissent must strictly comply with all the procedures required by the Montana statutes. These procedures are described later in this document, and a copy of the relevant statutory provisions is attached as Appendix B . For more information on dissenters rights, see “The Merger – Dissenters’ Rights of Appraisal.”

Regulatory Matters

Each of Glacier and TSB has agreed to use its reasonable best efforts to obtain all regulatory approvals required by the merger agreement and the transactions contemplated by the merger agreement. These approvals include approval from the Federal Deposit Insurance Corporation and the Commissioner of the Montana Division of Banking and Financial Institutions. Applications have been filed with these regulatory bodies seeking such approvals. We expect to obtain all such regulatory approvals, although we cannot be certain if or when we will obtain them. See “The Merger – Regulatory Requirements.”

Conditions to Completion of the Merger

Currently, Glacier and TSB expect to complete the merger during the third quarter of 2016. As more fully described in this proxy statement and in the merger agreement, the completion of the merger depends on a number of conditions being satisfied or, where legally permissible, waived. Neither Glacier nor TSB can provide assurance as to when or if all of the conditions to the merger can or will be satisfied or waived. See “The Merger – Conditions to the Merger.”

Termination of the Merger Agreement

The merger agreement provides that either Glacier or TSB may terminate the merger agreement either before or after the TSB special meeting, under certain circumstances. Among other things, the merger agreement provides that Glacier may terminate the merger agreement if the average trading price of its common stock, determined pursuant to the merger agreement, is above $27.05, unless TSB agrees to accept a reduced number of shares of Glacier common stock. If the average closing price is (i) below $19.99 but not less than $19.00 and the price of Glacier common stock has underperformed the KBW Regional Banking Index by more than 10%, or (ii) is below $19.00, TSB may elect to terminate the merger agreement, unless Glacier elects to increase the total number of shares or amount of cash to be issued, in order to avoid termination of the merger agreement. See “The Merger – Termination of the Merger Agreement.”

Termination Fees

If either party terminates the merger agreement due to specified breaches of the merger agreement by the other party, the breaching party will be required to pay the non-breaching party a termination fee of $250,000. See “The Merger – Termination Fees.”

Break-Up Fee

The merger agreement provides that TSB must pay Glacier a break-up fee of $590,000 if the merger agreement is terminated (i) by Glacier because the TSB Board fails to recommend approval of the merger agreement by TSB’s shareholders or modifies, withdraws or adversely changes its recommendation, or (ii) by the TSB Board due to its determination that an acquisition proposal received by TSB constitutes a “superior proposal,” as defined in the merger agreement, which is acted upon by TSB, or (iii) by Glacier because an acquisition event with respect to TSB has occurred. In addition, a break-up fee of $590,000 will be due if (1) Glacier terminates the merger agreement due to a failure of TSB’s shareholders to approve the merger agreement following a third party proposal to engage in, or enter into an agreement with respect to, an acquisition event, and (2) prior to one year after such termination, TSB enters into an agreement, or publicly announces its intention to engage in an acquisition event or within 18 months such an acquisition event will have occurred. It should be noted, however, that the failure of TSB’s shareholders to approve the merger agreement would not in and of itself trigger the obligation to pay the break-up fee, unless one of the foregoing factors also exists.

TSB agreed to pay the break-up fee under the circumstances described above in order to induce Glacier to enter into the merger agreement. This arrangement could have the effect of discouraging other companies from trying to acquire TSB. See “The Merger – Break-up Fee.”

TSB Shareholders’ Rights After the Merger

The rights of TSB shareholders are governed by Montana law, as well as by TSB’s articles of incorporation and bylaws. After completion of the merger, the rights of the former TSB shareholders receiving Glacier common stock in the merger will be governed by Montana law and by Glacier’s articles of incorporation and bylaws. Although Glacier’s articles of incorporation and bylaws are similar in many ways to TSB’s articles of incorporation and bylaws, there are some substantive and procedural differences that will affect the rights of TSB shareholders. See “Comparison of Certain Rights of Holders of Glacier and TSB Common Stock.”

RISK FACTORS

In addition to the other information contained in or incorporated by reference into this document, including the matters addressed under the caption “Cautionary Note Regarding Forward-Looking Statements,” you should consider the matters described below carefully in determining whether or not to approve the merger agreement and the transactions contemplated by the merger agreement.

Risks Associated with the Proposed Merger

Because the market price of the Glacier common stock may fluctuate, you cannot be sure of the value of the shares of Glacier common stock that you will receive.

At the time of the TSB special shareholder meeting, and prior to the closing of the merger, you will not be able to determine the value of the Glacier common stock that you would receive upon completion of the merger. Any change in the market price of Glacier common stock prior to completion of the merger will affect the value of the merger consideration that TSB shareholders will receive. Common stock price changes may result from a variety of factors, including but not limited to general market and economic conditions, changes in Glacier’s business, operations and prospects, and regulatory considerations. Many of these factors are beyond the control of Glacier or TSB. You should obtain current market prices for Glacier common stock.

The merger agreement provides that the number of shares of Glacier common stock to be issued for each share of TSB common stock in the merger may be decreased or increased, as the case may be, if the average trading price of Glacier common stock, determined pursuant to the merger agreement, is greater than or less than specified prices. If Glacier’s average trading price is greater than $27.05 and Glacier elects to terminate the merger agreement, the TSB Board would make the decision, without resoliciting the vote of TSB shareholders, whether or not to elect to accept a decrease on a per-share basis in the number of Glacier shares to be issued in the merger in lieu of such termination. See “The Merger – Termination of the Merger Agreement.”

The merger agreement limits TSB’s ability to pursue other transactions and provides for the payment of a break-up fee if TSB does so.

While the merger agreement is in effect, subject to very narrow exceptions, TSB and its directors, officers and agents are prohibited from initiating or encouraging inquiries with respect to alternative acquisition proposals. The prohibition limits TSB’s ability to seek offers that may be superior from a financial point of view from other possible acquirers. If TSB receives an unsolicited proposal from a third party that is superior from a financial point of view to that made by Glacier and the merger agreement is terminated, TSB may be required to pay a $590,000 break-up fee. This fee makes it less likely that a third party will make an alternative acquisition proposal. See “The Merger – Break-Up Fee.”

Under certain conditions, the merger agreement requires TSB to pay a termination fee.

Under certain circumstances (generally involving TSB’s breach of its representations and covenants in the merger agreement), Glacier can terminate the merger agreement and require TSB to pay a termination fee of $250,000. See “The Merger – Termination Fees.”

Combining our two companies may be more difficult, costly or time-consuming than we expect.

Glacier and TSB have operated and, until the completion of the merger, will continue to operate, independently. Although Glacier has successfully completed a number of mergers in the recent past, it is possible that the integration of TSB into Glacier Bank could result in the loss of key employees, the disruption of the ongoing business of TSB or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with customers and employees or to achieve the anticipated benefits of the merger. As with any merger of banking institutions, there also may be disruptions that cause us to lose customers or cause customers to take their deposits out of TSB.

Unanticipated costs relating to the merger could reduce Glacier’s future earnings per share.

Glacier believes that it has reasonably estimated the likely costs of integrating the operations of TSB into Glacier Bank, and the incremental costs of operating as a combined financial institution. However, it is possible that unexpected transaction costs or future operating expenses, as well as other types of unanticipated adverse developments, could have a material adverse effect on the results of operations and financial condition of Glacier after the merger. If the merger is completed and unexpected costs are incurred, the merger could have a dilutive effect on Glacier’s earnings per share, meaning earnings per share could be less than if the merger had not been completed.

Glacier has provisions in its articles of incorporation that could impede a takeover of Glacier.

Glacier’s amended and restated articles of incorporation contain provisions providing for, among other things, preferred stock and super majority shareholder approval of certain business combinations. Although these provisions were not adopted for the express purpose of preventing or impeding the takeover of Glacier without the approval of Glacier’s board of directors, they may have that effect. Such provisions may prevent you from taking part in a transaction in which you could realize a premium over the current market price of Glacier common stock. See “Comparison of Certain Rights of Holders of Glacier and TSB Common Stock” for a description of Glacier’s potential takeover provisions.

Risks Associated with Glacier’s Business

Glacier is, and will continue to be, subject to the risks described in Glacier’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, as updated by a Quarterly Report on Form 10-Q for the quarter ended March 31, 2016 and subsequent Current Reports on Form 8-K and Quarterly Reports on Form 10-Q, all of which are filed with the SEC and incorporated by reference into this proxy statement/prospectus. See “Documents Incorporated by Reference” and “Where You Can Find More Information About Glacier” included elsewhere in this proxy statement/prospectus.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This document, including information included or incorporated by reference in this document may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, (i) statements about the benefits of the merger, including future financial and operating results, cost savings, enhancements to revenue and accretion to reported earnings that may be realized from the merger; (ii) statements about our respective plans, objectives, expectations and intentions and other statements that are not historical facts; and (iii) other statements identified by words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” or words of similar meaning. These forward-looking statements are based on current beliefs and expectations of management and are inherently subject to significant

business, economic and competitive uncertainties and contingencies, many of which are beyond Glacier’s and TSB’s control. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change.

The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations in the forward-looking statements:

•

the merger may not close when expected or at all because required regulatory, shareholder or other approvals and other conditions to closing are not received on a timely basis or at all;

•

Glacier’s stock price could change before closing of the merger, due to among other things stock market movements and the performance of financial companies and peer group companies, over which Glacier has no control;

•

benefits from the merger may not be fully realized or may take longer to realize than expected, including as a result of changes in general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree competition in the geographic and business areas in which Glacier and TSB operate;

•

TSB’s business may not be integrated into Glacier’s successfully, or such integration may take longer to accomplish than expected;

•

the anticipated growth opportunities and cost savings from the merger may not be fully realized or may take longer to realize than expected;

•

operating costs, customer losses and business disruption following the merger, including adverse developments in relationships with employees, may be greater than expected; and

•

management time and effort may be diverted to the resolution of merger-related issues.

Additional factors that could cause actual results to differ materially from those expressed in the forward-looking statements are discussed in Glacier’s reports filed with the SEC.

All subsequent written and oral forward-looking statements concerning the proposed transaction or other matters attributable to Glacier or TSB or any person acting on behalf of Glacier or TSB are expressly qualified in their entirety by the cautionary statements above. Neither Glacier nor TSB undertakes any obligation to update any forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements are made.

Non-GAAP Financial Measures

In addition to the results presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”), the table above contains certain non-GAAP financial measures. Glacier believes that providing these non-GAAP financial measures provides investors with information useful in understanding Glacier’s financial performance, performance trends, and financial position. While Glacier uses these non-GAAP measures in its analysis of Glacier’s performance, this information should not be considered an alternative to measurements required by GAAP.

The reconciling item between the GAAP and non-GAAP financial measures was the third quarter of 2011 goodwill impairment charge (net of tax) of $32.6 million.

•

The goodwill impairment charge was $40.2 million with a tax benefit of $7.6 million which resulted in a goodwill impairment charge (net of tax) of $32.6 million. The tax benefit applied only to the $19.4 million of goodwill associated with taxable acquisitions and was determined based on Glacier’s marginal income tax rate of 38.9%.

•

The basic and diluted earnings per share reconciling items were determined based on the goodwill impairment charge (net of tax) divided by the weighted average diluted shares of 71,915,073.

•

The goodwill impairment charge (net of tax) was included in determining earnings for both the GAAP return on average assets and GAAP return on average equity. The average assets used in the GAAP and non-GAAP return on average assets ratios were $6.9 billion and $6.9 billion, respectively, for the year ended December 31, 2011. The average equity used in the GAAP and non-GAAP return on average equity ratios were $858 million and $866 million, respectively, for the year ended December 31, 2011.

•

The dividend payout ratio is calculated by dividing dividends declared per share by basic earnings per share. The non-GAAP dividend payout ratio uses the non-GAAP basic earnings per share for calculating the ratio.

TSB SPECIAL SHAREHOLDERS’ MEETING

Date, Time, Place

The TSB special meeting of shareholders will be held on July 20, 2016, at 8:00 a.m. local time, at 3660 Mullan Road, Missoula, Montana.

As described below under “Vote Required and Quorum,” approval of the merger agreement requires the affirmative vote of at least two-thirds (66 2/3%) of the shares of TSB’s outstanding common stock. The proposal to adjourn the special meeting, if necessary or appropriate, including adjournments to solicit additional proxies, will be approved if the votes cast in favor of the proposal exceed the votes cast against the proposal, assuming a quorum is present. If less than a quorum is represented at the special meeting, a majority of the shares so represented may adjourn the special meeting.

Purpose

At the special meeting, TSB shareholders will:

•

Consider and vote on a proposal to approve the Agreement and Plan of Merger, dated as of April 20, 2016, among Glacier, Glacier Bank, and TSB, under the terms of which TSB will merge with and into Glacier Bank. The merger agreement is attached as Appendix A .

See “The Merger – Dissenters’ Rights of Appraisal” and Appendix B .

The directors of TSB have agreed to vote all shares of TSB common stock held or controlled by them in favor of approval of the merger agreement. A total of 343,874 outstanding shares of TSB common stock, or approximately 19.37% of the outstanding shares of TSB common stock, are covered by the voting agreement. See “The Merger – Interests of Certain Persons in the Merger – Voting Agreement.”

Vote Required and Quorum

The affirmative vote of the holders of at least two-thirds (66 2/3%) of the shares of TSB’s outstanding common stock is required to approve the merger agreement. At least a majority of the total outstanding shares of TSB common stock must be present, either in person or by proxy, in order to constitute a quorum for the special meeting. For purposes of determining a quorum, abstentions and broker nonvotes (that is, proxies from brokers or nominees, indicating that such person has not received instructions from the beneficial owners or other persons entitled to vote shares as to a matter with respect to which the broker or nominees do not have discretionary power to vote) are counted in determining the shares present at a meeting.

For voting purposes, however, only shares actually voted for the approval of the merger agreement, and neither abstentions nor broker nonvotes, will be counted as favorable votes in determining whether or not the merger agreement is approved by the holders of TSB common stock. As a result, abstentions and broker nonvotes will have the same effect as votes against approval of the merger agreement.

The proposal to approve one or more adjournments of the special meeting, if necessary or appropriate, including adjournments to solicit additional proxies in favor of the merger agreement, will be

approved if the votes cast in favor of the proposal exceed the votes against the proposal, assuming a quorum is present. If less than a quorum is represented at the special meeting, a majority of the shares so represented may adjourn the special meeting.

Voting, Solicitation, and Revocation of Proxies

If the enclosed proxy card is duly executed and received in time for the special meeting, it will be voted in accordance with the instructions given. If the proxy card is duly executed and received but no instructions are given, it is the intention of the persons named in the proxy to vote the shares represented by the proxy for the approval of the merger agreement, for the proposal to approve one or more adjournments to solicit additional proxies, and in the proxy holder’s discretion on any other matter properly coming before the meeting. Any proxy given by a shareholder may be revoked before its exercise by:

•

sending written notice to the Secretary of TSB;

•

completing and submitting a later-dated proxy; or

•

attending and voting at the special meeting in person.

TSB is soliciting the proxy for the special meeting on behalf of the TSB Board. TSB will bear the cost of solicitation of proxies from its shareholders. In addition to using the mail, TSB may solicit proxies by personal interview, telephone, and facsimile. Banks, brokerage houses, other institutions, nominees, and fiduciaries will be requested to forward their proxy soliciting material to their principals and obtain authorization for the execution of proxies. TSB does not expect to pay any compensation for the solicitation of proxies. However, TSB will, upon request, pay the standard charges and expenses of banks, brokerage houses, other institutions, nominees, and fiduciaries for forwarding proxy materials to and obtaining proxies from their principals.

Voting in Person at the Special Meeting

Shareholders of Record . Shares held directly in your name as the shareholder of record may be voted in person at the special meeting. If you choose to vote your shares of TSB common stock in person, please bring the enclosed proxy card or proof of identification. Even if you plan to attend the special meeting, we recommend that you vote your shares of TSB common stock in advance as described above so that your vote will be counted if you later decide not to attend the special meeting.

Beneficial Owner . Shares held in street name may be voted in person by you only if you bring an account statement or letter from the nominee indicating that you were the beneficial owner of the shares on the record date.

BACKGROUND OF AND REASONS FOR THE MERGER

Background of the Merger

During 2015, the directors of TSB discussed and considered strategic alternatives to enhance shareholder value and achieve future shareholder liquidity, including stock buyback and merger and acquisition activity. Glacier’s management team had kept in touch with the management of TSB through the years and had expressed Glacier’s potential interest in acquiring TSB.

In mutual discussions between TSB and Glacier in late 2015, it was determined that there was enough interest on TSB’s part to hold a meeting between the two parties. TSB identified Glacier as a

potentially attractive future merger partner in view of Glacier’s successful track record with other acquisitions, its emphasis on locally managed community banking, its existing presence in Missoula and other Montana communities, and its strong financial performance.

On December 11, 2015, TSB signed a non-disclosure agreement with Glacier for the confidential exchange of nonpublic information in connection with a possible transaction, and James Salisbury, Chairman and CEO of TSB, met with Michael Blodnick, Glacier’s CEO, Randall Chesler, President of Glacier Bank, Scott Burke, President and CEO of Glacier’s First Security Bank operating division, and Bill Bouchee, a director of Glacier’s First Security Bank operating division, in Ronan, Montana to discuss a potential merger between TSB and Glacier. Thereafter, Glacier delivered a due diligence request list identifying the financial and operational information that Glacier would require in order to submit a preliminary proposal.

TSB contacted Davidson on December 17, 2015 about a possible engagement to act as TSB’s investment banking advisor. TSB engaged Davidson on December 28, 2015 as its investment banking advisor in the transaction.

On January 25, 2016, representatives from Davidson participated on a conference call with the TSB Board to discuss current market conditions for banks, merger and acquisition activity and pricing for comparable banks and a preliminary model of what a combination with Glacier could look like.

On February 16, 2016, representatives from Davidson met with Mr. Salisbury, Anne Robinson, Chief Financial Officer of TSB, Mr. Blodnick, Mr. Chesler and Mr. Burke in Polson, Montana to further discuss a potential merger. TSB and Davidson presented the rationale for the possible transaction, detailed forecasts of TSB’s financial performance, potential cost savings, a detailed merger model and possible next steps to help arrive at a transaction.

On February 24, 2016, Glacier delivered to TSB a term sheet that called for an $11.8 million purchase price that would be 60% in the form of Glacier stock and 40% in cash. After discussing the proposed term sheet with a TSB board committee, Davidson and TSB provided a counter term sheet to Glacier on February 26, 2016 that asked for additional consideration and a purchase price that was 70% in the form of Glacier stock and 30% in cash.

The TSB Board, along with TSB’s legal counsel and financial advisor, met on February 29, 2016 to review the proposal. As part of that board meeting, Davidson presented a financial analysis of the Glacier proposal as compared to TSB continuing to operate independently and in a manner consistent with current operations or, alternatively, following a new strategy involving stock buybacks and possibly enhanced dividends to shareholders. Davidson’s analysis led to a determination that the Glacier offer was superior in both cases.

The parties and their legal and financial advisors further negotiated the wording of several aspects of the term sheet, and on March 1, 2016, Mr. Blodnick and Mr. Salisbury signed the term sheet.

Between March 1 and April 20, 2016, Glacier, TSB and their respective financial and legal advisors conducted appropriate due diligence and drafted and negotiated the merger agreement and related ancillary agreements. Glacier’s due diligence review included an extensive loan review conducted by DLS Consulting and supported by Glacier’s Chief Credit Officer.

On April 11, 2016, as part of its monthly board of directors meeting, the TSB Board, along with its legal counsel, met to discuss the draft agreement and material terms of the proposed transaction and provided preliminary approval of the transaction.

On April 20 , 2016, the TSB Board, together with its legal counsel and Davidson, met to consider approval of the merger agreement. Davidson presented its analysis and opinion as to the fairness of the merger, from a financial point of view. Among other matters considered, the board reviewed the specific terms of the merger agreement, the form and value of the consideration to be received by shareholders, the price and historical performance of Glacier stock, current market conditions including comparable bank merger and acquisition transactions, and the implications of the merger to TSB’s employees, customers, and communities. After due consideration of these and other matters, and taking into consideration the fairness opinion delivered by Davidson, the TSB Board unanimously approved entering into the merger agreement and related ancillary agreements.

On April 20, 2016, the board of directors of Glacier, together with its legal counsel, met to consider approval of the merger agreement. Glacier management presented updated pro forma financial analyses and Glacier’s counsel presented a review of the key terms of the merger documents. Among other matters discussed, the board of directors and Glacier’s advisors discussed the results of due diligence reviews, the terms of the merger agreement and ancillary documents, key pricing metrics, the pro forma financial impact of the merger to Glacier’s shareholders, risks of the merger, and the timing and process for consummation of the merger, including the results of preliminary discussions with bank regulators. After due consideration of these and other matters, the Glacier board of directors unanimously approved entering into the merger agreement and related ancillary agreements.

On April 20, 2016, the parties executed the merger agreement and related documents. After the close of business on April 20, the parties issued a joint press release announcing the merger, and Glacier filed a Current Report on Form 8-K with the SEC on April 21, 2016.

Reasons For The Merger – TSB

At the board meeting held on April 20, 2016, the TSB Board determined that the terms of the merger agreement were in the best interests of TSB and its shareholders. In the course of reaching the decision to approve the merger agreement, the TSB Board consulted with Davidson, its financial advisor, and Bjornson Law Offices, PLLC, its legal counsel. In reaching their determination, the TSB Board considered a number of factors. Such factors also constituted the reasons that the TSB Board determined to approve the merger agreement and to recommend that TSB shareholders vote in favor of the merger agreement. Such reasons included the following:

•

the terms of the merger agreement and the value, form and mix of consideration to be received by TSB shareholders in the merger;

•

the historical trading ranges for Glacier common stock;

•

the historic and prospective business of TSB;

•

the likely impact of the merger on the employees and customers of TSB;

•

the future employment opportunities for the existing employees of TSB;

•

information concerning Glacier’s financial condition and results of operations as well as the likelihood that Glacier would be able to obtain regulatory approval for the merger;

•

the opinion of Davidson that the merger consideration to be received by TSB shareholders in the merger is fair from a financial point of view;

•

the expectation that TSB shareholders would have the opportunity to continue to participate in the growth of the combined company and would also benefit from the significantly greater liquidity of the trading market for Glacier common stock;

•

that Glacier has historically paid cash dividends on its common stock;

•

the fact that Glacier’s common stock is widely held and has an active trading market; whereas TSB’s stock is not actively traded;

•

the provisions in the merger agreement that provide for the ability of the TSB Board to respond to an unsolicited acquisition proposal that the TSB Board determines in good faith is a superior proposal as defined in the merger agreement;

•

the provisions of the merger agreement that provide for the ability of the TSB Board to terminate the merger agreement, subject to certain conditions including the payment of a break-up fee, if TSB has entered into a letter of intent or other agreement with respect to a superior proposal; and

•

the likelihood of the merger being approved by applicable regulatory authorities without undue conditions or delay.

The TSB Board also considered a number of uncertainties and risks in its deliberations concerning the transactions contemplated by the merger agreement, including the following:

•

that a portion of the merger consideration will be paid through the issuance of a fixed number of shares of Glacier common stock and any decrease in the market price of Glacier common stock will result in a reduction in the aggregate merger consideration to be received by TSB shareholders at the time of completion of the merger subject to the adjustment procedures described under “The Merger – Termination of the Merger Agreement”;

•

that TSB shareholders will not necessarily know or be able to calculate the actual value of the merger consideration which they would receive upon completion of the merger;

•

the possible disruption to TSB’s business that may result from the announcement of the merger and the resulting distraction of management’s attention from the day-to-day operations of TSB’s business; and

•

the restrictions contained in the merger agreement on the operation of TSB’s business during the period between signing of the merger agreement and completion of the merger, as well as the other covenants and agreements of TSB contained in the merger agreement.

The foregoing discussion of the reasons that led the TSB Board to approve the merger agreement and recommend that TSB’s shareholders vote in favor of the merger agreement is not intended to be exhaustive, but is believed to include all of the material reasons for the TSB Board’s decision. In

reaching their determination to approve and recommend the transaction, the TSB Board based its recommendation on the totality of the information presented to it and did not assign any relative or specific weights to the reasons considered in reaching that determination. Individual directors may have given differing weights to different reasons. After deliberating with respect to the merger with Glacier, considering, among other things, the matters discussed above and the opinion of Davidson referred to above, the TSB Board unanimously approved the merger agreement and the merger with Glacier as being in the best interests of TSB and its shareholders.

Opinion of Financial Advisor to TSB

On December 28, 2015, TSB entered into an engagement agreement with Davidson to render financial advisory and investment banking services to TSB. As part of its engagement, Davidson agreed to assist TSB in analyzing, structuring, negotiating and, if appropriate, effecting a transaction between TSB and another corporation or business entity. Davidson also agreed to provide the TSB Board with an opinion as to the fairness, from a financial point of view, to the holders of TSB common stock, of the consideration in the proposed merger. TSB engaged Davidson because Davidson is a nationally recognized investment banking firm with substantial experience in transactions similar to the merger and is familiar with TSB and its business. As part of its investment banking business, Davidson is continually engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

On April 20, 2016, the TSB Board held a meeting to evaluate the proposed merger. At this meeting, Davidson reviewed the financial aspects of the proposed merger and rendered an opinion to the TSB board that, as of such date and based upon and subject to assumptions made, procedures followed, matters considered and limitations on the review undertaken, the consideration to be paid to the holders of the TSB common stock in the proposed merger was fair, from a financial point of view.

The full text of Davidson’s written opinion, dated April 20, 2016, is attached as Appendix C to this proxy statement and is incorporated herein by reference. The description of the opinion set forth herein is qualified in its entirety by reference to the full text of such opinion. TSB’s shareholders are urged to read the opinion in its entirety.

Davidson’s opinion speaks only as of the date of the opinion, and Davidson undertakes no obligation to revise or update its opinion. The opinion is directed to the TSB Board and addresses only the fairness, from a financial point of view, of the consideration to be paid to the holders of TSB common stock in the proposed merger. The opinion does not address, and Davidson expresses no view or opinion with respect to, (i) the underlying business decision of TSB to engage in or proceed with the merger, (ii) the relative merits or effect of the merger as compared to any strategic alternatives or business strategies or combinations that may be or may have been available to or contemplated by TSB or the TSB Board, or (iii) any legal, regulatory, accounting, tax or similar matters relating to TSB, its shareholders or relating to or arising out of the merger. The opinion expresses no view or opinion as to any terms or other aspects of the merger. TSB and Glacier determined the consideration to be paid through the negotiation process. The opinion does not constitute a recommendation to any TSB shareholder as to how such shareholder should vote at the TSB meeting on the merger or any related matter. The opinion does not express any view as to the fairness of the amount or nature of the compensation to any of TSB’s or Glacier’s officers, directors or employees, or any class of such persons, relative to the merger consideration. The opinion has been reviewed and approved by Davidson’s Fairness Opinion Committee in conformity with its policies and procedures established under the requirements of Rule 5150 of the Financial Industry Regulatory Authority.

Davidson has reviewed the registration statement on Form S-4 of which this proxy statement/prospectus is a part and consented to the inclusion of its opinion to the TSB Board as Appendix C to this proxy statement/prospectus and to the references to Davidson and its opinion contained herein. A copy of the consent of Davidson is attached as Exhibit 23.3 to the registration statement on Form S-4.

In connection with rendering its opinion, Davidson reviewed, analyzed and relied upon material bearing upon the merger relating to the financial and operating condition of TSB and Glacier and the merger itself, including among other things, the following:

•

drafts of the merger agreement (including disclosure schedules) and voting agreement as of April 9, 2016;

•

certain financial statements and other historical financial and business information about TSB and Glacier made available to Davidson from published sources and/or from the internal records of TSB that Davidson deemed relevant;

•

the current market environment generally and the banking environment in particular;

•

the current and historical market prices and trading activity of the TSB common stock with that of certain other publicly traded companies that Davidson deemed relevant;

•

the current and historical market prices and trading activity of the Glacier common stock with that of certain other publicly traded companies that Davidson deemed relevant;

•

the net present value of TSB with consideration of projected financial results through 2021 (based on 2016-2018 TSB budget and projections and Davidson growth projections in years thereafter that were confirmed by management);

•

the financial terms of certain other similar transactions in the financial institutions industry, to the extent publicly available;

•

the market and trading characteristics of public companies and public bank holding companies in particular;

•

the pro forma financial impact of the merger on Glacier, taking into consideration the amounts and timing of the transaction costs and cost savings;

•

the net present value of TSB and Glacier, on a pro forma basis with the pro forma financial impact of the merger, with consideration of projected financial results; and

•

such other information, financial studies, analyses and investigations and financial, economic and market criteria as Davidson considered relevant, including discussions with management and other representatives and advisors of TSB concerning the business, financial condition, results of operations and prospects of TSB.

In arriving at its opinion, Davidson has assumed and relied upon the accuracy and completeness of all information supplied or otherwise made available to Davidson, discussed with or reviewed by or for Davidson, or publicly available, and Davidson has not assumed responsibility for independently verifying such information or undertaken an independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of TSB or Glacier, nor did Davidson make an independent appraisal or analysis of TSB or Glacier with respect to the merger. In addition, Davidson has not assumed any obligation to conduct, nor has Davidson conducted, any physical inspection of the properties or facilities of TSB or Glacier. Davidson has further relied on the assurances of management of TSB and Glacier that

they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. Davidson did not make an independent evaluation or appraisal of the specific assets or liabilities, including the amount of any fair value adjustments per Business Combinations Topic ASC 805. Davidson did not make an independent evaluation of the adequacy of the allowance for loan losses of TSB or Glacier nor has Davidson reviewed any individual credit files relating to TSB or Glacier. Davidson has assumed that the respective allowances for loan losses for both TSB and Glacier are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. Davidson has assumed that there has been no material change in TSB’s or Glacier’s assets, financial condition, results of operations, business or prospects since the date of the most recent financial statements provided to Davidson. Davidson has assumed in all respects material to its analysis that TSB and Glacier will remain as going concerns for all periods relevant to its analysis. Davidson has also assumed in all respects material to its analysis that all of the representations and warranties contained in the merger agreement and all related agreements are true and correct, that each party to such agreements will perform all of the covenants required to be performed by such party under such agreements and that the conditions precedent in the merger agreement are not waived. Davidson has assumed that in the course of obtaining the necessary regulatory or other consents or approvals (contractual or otherwise) for the merger, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that will have a material adverse effect on the contemplated benefits of the merger. Davidson’s opinion is necessarily based upon information available to Davidson and economic, market, financial and other conditions as they exist and can be evaluated on the date the fairness opinion letter was delivered to the TSB Board.

Set forth below is a summary of the material financial analyses performed by Davidson in connection with rendering its opinion. The summary of the analyses of Davidson set forth below is not a complete description of the analysis underlying its opinion, and the order in which these analyses are described below is not indicative of any relative weight or importance given to those analyses by Davidson. The following summaries of financial analyses include information presented in tabular format. You should read these tables together with the full text of the summary financial analyses, as the tables alone are not a complete description of the analyses.

Unless otherwise indicated, the following quantitative information, to the extent it is based on market data, is based on market data as of April 15, 2016, the trading day used by Davidson prior to the date which Davidson delivered the fairness opinion letter to the TSB Board, and is not necessarily indicative of market conditions after such date.

Control Premium Analysis

Davidson performed a control premium analysis and reviewed the acquisitions of publicly traded banks from January 1, 2004 to April 15, 2016 and for OTC Market-traded banks from January 1, 2004 to April 15, 2016. Control premiums as measured by the excess of the prior day stock price of the acquired company ranged from an average of 32.1% to 40.7%, as compared to the control premium for TSB of 43.8% as of April 15, 2016.

Pro Forma Dividend Pick-Up Analysis

Davidson reviewed the dividend and distribution history of TSB and Glacier common stock, including special dividends and distributions, since the beginning of 2000. In fourth quarter 2015, TSB declared and paid a $0.10 per common share annual distribution. In fourth quarter 2015, Glacier declared and paid a $0.19 per common share quarterly dividend and declared a $0.30 per common share special dividend, which was paid on January 21, 2016. In first quarter 2016, Glacier declared a $0.20 per common share quarterly dividend, which equates to an annualized dividend of $0.80, which was paid on April 21, 2016. Based on market data as of April 15, 2016 and using the exchange ratio, on a pro forma basis, TSB common shareholders would receive an annual dividend of $0.16 per share, or $0.22 per share including Glacier’s special annual dividend.

Net Present Value Analysis for Treasure State Bank

Davidson performed an analysis that estimated the net present value per share of TSB common stock under various circumstances. The analysis assumed: (i) TSB performed in accordance with TSB management’s financial forecasts for the years ending December 31, 2016, December 31, 2017 and December 31, 2018; and (ii) an estimated long-term growth rate for the years thereafter, as discussed with and confirmed by TSB management. To approximate the terminal value of TSB common stock at December 31, 2021, Davidson applied price-to-earnings multiples of 16.0x to 21.0x and multiples of tangible book value ranging from 115.0% to 140.0%. The income streams and terminal values were then discounted to present values using different discount rates ranging from 10.0% to 16.0%, chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of TSB’s common stock. In evaluating the discount rate, Davidson used industry standard methods of adding the current risk-free rate, which is based on the 10-year Treasury yield, plus the published Ibbotson Equity Risk Premium, plus the published Ibbotson Size Premium, plus the published Ibbotson Industry Premium.

At the meeting of the TSB Board on April 20, 2016, Davidson noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

As illustrated in the following tables, the analysis indicates an imputed range of values per share of TSB common stock of $3.52 to $5.97 when applying the price-to-earnings multiples to the financial forecasts and $3.79 to $6.05 when applying the multiples of tangible book value to the financial forecasts.

Financial Impact Analysis

Davidson performed pro forma merger analyses that combined projected income statement and balance sheet information of TSB and Glacier. Assumptions regarding the accounting treatment, acquisition adjustments and cost savings were used to calculate the financial impact that the merger would have on certain projected financial results of Glacier. In the course of this analysis, Davidson used the average FactSet Research Systems, Inc. consensus earnings estimates for Glacier for the years ending December 31, 2016 and December 31, 2017 and used the financial forecast, provided by TSB management, for TSB for the years ending December 31, 2016, December 31, 2017 and December 31, 2018. This analysis indicated that the merger is expected to be accretive to Glacier’s estimated earnings per share in 2016, after excluding non-recurring transaction-related expenses. The analysis also indicated that the merger is expected to be neutral to tangible book value per share for Glacier and that Glacier would maintain capital ratios in excess of those required for Glacier to be considered well capitalized under existing regulations. For all of the above analyses, the actual results achieved by TSB and Glacier prior to and following the merger will vary from the projected results, and the variations may be material.

Davidson prepared its analyses for purposes of providing its opinion to the TSB Board as to the fairness, from a financial point of view, of the consideration to be paid to the holders of TSB common stock in the proposed merger and to assist the TSB Board in analyzing the proposed merger. The analyses do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than those suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties and their respective advisors, none of TSB, Glacier or Davidson or any other person assumes responsibility if future results are materially different from those forecasted.

Davidson’s opinion was one of many factors considered by the TSB Board in its evaluation of the merger and should not be viewed as determinative of the views of the TSB Board or management with respect to the merger or the merger consideration.

Davidson and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions. Davidson acted as financial advisor to TSB in connection with, and participated in certain of the negotiations leading to the merger. Davidson is a full-service securities firm engaged in, among other things, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, and financing and brokerage activities for both companies and individuals. In the ordinary course of these

activities, Davidson and its affiliates may provide such services to TSB, Glacier, and their respective affiliates; may actively trade the debt and equity securities (or related derivative securities) of TSB and Glacier for their own account and for the accounts of their customers; and may at any time hold long and short positions of such securities. TSB selected Davidson as its financial advisor because Davidson is a recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement dated December 28, 2015, TSB engaged Davidson as its financial advisor in connection with the contemplated transaction. Pursuant to the terms of the engagement letter, TSB agreed to pay Davidson a non-refundable cash retainer fee of $15,000 upon execution of the engagement letter. TSB agreed to pay Davidson a cash fee of $75,000 concurrently with the rendering of its opinion. TSB will pay to Davidson at the time of closing of the merger a contingent cash fee equal to 1.50% of the aggregate consideration to be paid to TSB shareholders. TSB has also agreed to reimburse Davidson for all reasonable out-of-pocket expenses, including fees of counsel, and to indemnify Davidson and certain related persons against specified liabilities, including liabilities under the federal securities laws, relating to or arising out of its engagement.

Raymond Round, a Senior Vice President and Financial Advisor in Davidson’s Individual Investor Group, was a founder and has been a member of the TSB Board since its formation and has received compensation consistent with that received by other directors of TSB during the same period. In the past, Davidson has provided certain investment banking services to TSB and its affiliates, has had a material relationship with TSB and its affiliates and has received compensation and reimbursement of out-of-pocket expenses for such services. During the two years preceding the date of the opinion, Davidson had not received compensation from TSB. In the past, Davidson has advised Glacier on numerous transactions and helped raise debt and equity capital for Glacier. As of April 20, 2016, Davidson was not engaged on any assignments by Glacier. Additionally, Davidson may provide investment banking services to the combined company in the future and may receive future compensation.

Recommendation of the TSB Board of Directors

The TSB Board has unanimously concluded that the proposed merger as described in the merger agreement is in the best interest of TSB and its shareholders. After carefully considering the proposed merger, the board of directors unanimously recommends that the shareholders of TSB vote “FOR” the approval of the merger agreement.

THE MERGER

The following is a brief description of the material aspects of the merger. There are other aspects of the merger that are not discussed below but that are contained in the merger agreement. You are being asked to approve the merger in accordance with the terms of the merger agreement, and you are urged to read the merger agreement carefully. The merger agreement is attached to this proxy statement/prospectus as Appendix A .

Basic Terms of the Merger

The merger agreement provides for the merger of TSB with and into Glacier Bank, Glacier’s wholly owned subsidiary. Following the merger, TSB will operate under Glacier Bank’s division, First Security Bank, and as a part of that division.

In the merger, TSB shareholders will receive a combination of Glacier common stock and cash for their TSB common stock, as described below. See “– Merger Consideration.”

While Glacier and TSB believe that they will receive the necessary regulatory approvals for the merger, there can be no assurance that such approvals will be received or, if received, as to the timing of such approvals or as to the ability to obtain such approvals on satisfactory terms. See “– Conditions to the Merger” and “– Regulatory Requirements.”

Merger Consideration

The merger agreement provides that as of the effective date of the merger, each share of TSB common stock will be converted into the right to receive a “unit” comprised of Glacier common stock and cash, as follows:

Stock Portion of Merger Consideration

0.2030 Glacier shares, subject to adjustment as follows: If the average closing price of Glacier stock calculated in accordance with the merger agreement exceeds $27.05, Glacier may elect to terminate the merger agreement, unless TSB elects to accept a decrease in the per-share number of Glacier shares to be issued in the merger. Conversely, if the average closing price is (i) below $19.99 but not less than $19.00 and the price of Glacier common stock has underperformed the KBW Regional Banking Index by more than 10%, or (ii) is below $19.00, TSB may elect to terminate the merger agreement, unless Glacier elects to increase the per-share number of Glacier shares or amount of cash to be issued.

Assuming for purposes of illustration only that the average closing price of Glacier common stock is $27.44 (which was the per-share closing price of Glacier common stock on June 7, 2016), TSB shareholders would instead receive 0.2001 shares of Glacier common stock for each share of TSB common stock. This exchange ratio reflects a decrease from 0.2030 Glacier shares for each TSB share because the June 7, 2016 Glacier closing price exceeds $27.05 and assumes that Glacier requires, and TSB accepts, a reduction in the exchange ratio as described in the preceding paragraph. The actual Glacier average closing price will not be determined until 10 days prior to the closing of the merger, and it cannot be predicted whether such average closing price will be above or below $27.05.

Glacier will not issue fractional shares, and will pay cash in lieu of such fractional shares, as described under “The Merger – Fractional Shares.”

Cash Portion of Merger Consideration

$1.9570 in cash, subject to adjustment as follows: If the adjusted “TSB Closing Capital” is less than $9,575,557, which is expected to be the “Closing Capital Requirement” (as defined below), the cash portion of each unit will be reduced on a pro rata basis based on the amount of such deficit.

The “TSB Closing Capital” is specifically defined in the merger agreement and is equal to an amount, estimated as of the closing date of the merger, equal to TSB’s capital stock, surplus and retained earnings determined in accordance with generally accepted accounting principles (“GAAP”) on a consolidated basis, net of goodwill and other intangible assets, calculated in the same manner in which TSB’s consolidated tangible equity capital at December 31, 2015 was calculated, after giving effect to adjustments, calculated in accordance with GAAP, for accumulated other comprehensive income or loss as reported on TSB’s balance sheet.

The TSB Closing Capital may be adjusted based on the estimated final amount of transaction-related expenses to be incurred by TSB, as determined and agreed upon between TSB and Glacier in accordance with the merger agreement (the “Final Transaction-Related Expenses”). To the extent the Final Transaction-Related Expenses exceed or are less than $1,100,000, the difference, on an after-tax basis, will be reflected as a pro-forma adjustment to the TSB Closing Capital, reducing or increasing the amount of the TSB Closing Capital, as the case may be.

If the TSB Closing Capital exceeds the Closing Capital Requirement, TSB will, upon written notice to Glacier and effective prior to the closing of the merger, declare and pay a special distribution in the amount of such excess. However, the amount of such dividend may be limited to the extent necessary to cause the merger of TSB with and into Glacier Bank to qualify as a tax-free reorganization under applicable provisions of the Internal Revenue Code.

Assuming for purposes of illustration only that (i) there is no reduction of the cash portion of the merger consideration, and (ii) the average closing price of Glacier common stock immediately prior to the closing of the merger is $27.44 (which was the closing price for Glacier common stock on June 7, 2016), each share of TSB common stock would receive consideration with a value equal to $7.4482, consisting of $1.9570 in cash and 0.2001 shares of Glacier common stock.

Fractional Shares

No fractional shares of Glacier common stock will be issued to any holder of TSB common stock in the merger. For each fractional share that would otherwise be issued, Glacier will pay cash in an amount equal to the fraction multiplied by the Glacier average closing price calculated as provided in the merger agreement. No interest will be paid or accrued on cash payable in lieu of fractional shares of Glacier common stock.

Effective Date of the Merger

Subject to the satisfaction or waiver of conditions to the obligations of the parties to complete the merger as set forth in the merger agreement, the effective date of the merger will be the date of issuance of a Certificate of Merger by the Montana Secretary of State, which is expected to occur on the date of closing. Subject to the foregoing, it is currently anticipated that the merger will be consummated during the third quarter of 2016. Either Glacier or TSB may terminate the merger agreement if the effective date does not occur on or before November 30, 2016.

Letter of Transmittal

Promptly following the effective date of the merger, Glacier’s exchange agent will send a letter of transmittal to each holder of record of TSB common stock. This mailing will contain instructions on how to surrender TSB common stock certificates or other evidence of ownership in exchange for the merger consideration that the holder is entitled to receive under the merger agreement.

With the exception of any proposed dissenting shares, each TSB stock certificate will, from and after the effective date of the merger, be deemed to represent and evidence only the right to receive the portion of the merger consideration payable with respect to such certificate. TSB shareholders must provide properly completed and executed letters of transmittal in order to effect the exchange of their shares of TSB common stock for (i) evidence of issuance in book entry form, or upon the request of the holder, stock certificates, representing Glacier common stock in payment of the stock portion of the merger consideration; (ii) a check, or at the election of the TSB shareholder, a wire transfer (but only if the amount of cash included in such shareholder’s merger consideration exceeds $100,000) in payment of the cash portion of the merger consideration; and/or (iii) a check representing the amount of cash in lieu of fractional shares, if any.

Lost, Stolen or Destroyed Certificates

If a certificate for TSB common stock has been lost, stolen or destroyed, the exchange agent will be authorized to issue or pay the holder’s merger consideration, if the holder provides Glacier’s exchange agent with (i) satisfactory evidence that the holder owns the TSB common stock and that the certificate is lost, stolen or destroyed, (ii) any appropriate affidavit or security Glacier’s exchange agent may require, and (iii) any reasonable assurances that Glacier or Glacier’s exchange agent may require.

Voting Agreement

The directors of TSB have entered into a voting agreement, dated as of April 20, 2016. In the voting agreement, each person agrees, among other things, to vote the shares of TSB common stock that he owns or controls in favor of the merger agreement. The persons who have entered into the voting agreement are entitled to vote a total of 343,874 outstanding shares of TSB common stock, which is approximately 19.37% of the total outstanding shares of TSB common stock.

Dissenters’ Rights of Appraisal

Under Montana law, TSB shareholders have the right to dissent from the merger and to receive payment in cash for the “fair value” of their shares of TSB common stock.

TSB shareholders electing to exercise dissenters’ rights must comply with the provisions of the Montana appraisal laws in order to perfect their rights. The following is intended as a brief summary of the material provisions of the procedures that a TSB shareholder must follow in order to dissent from the merger and perfect dissenters’ rights. This summary, however, is not a complete statement of all applicable requirements and is qualified in its entirety by reference to the Montana appraisal laws, the full text of which is set forth in Appendix B to this document.

A shareholder who wishes to assert dissenters’ rights must:

•

deliver to TSB before the special meeting written notice of the shareholder’s intent to demand payment for the shareholder’s shares if the merger is completed, and

•

not vote the shares in favor of the merger.

A shareholder wishing to deliver a notice asserting dissenters’ rights should hand deliver or mail the notice to the following address:

Treasure State Bank

3660 Mullan Road

Missoula, Montana 59808

Attention: James A. Salisbury, Chief Executive Officer

A shareholder who wishes to exercise dissenters’ rights generally must dissent with respect to all of the shares the shareholder owns or over which the shareholder has the power to direct the vote. However, if a record shareholder is a nominee for several beneficial shareholders, some of whom wish to dissent and some of whom do not, then the record holder may dissent with respect to all the shares beneficially owned by any one person by notifying TSB in writing of the name and address of each person on whose behalf the record shareholder asserts dissenters’ rights. A beneficial shareholder may assert dissenters’ rights directly by submitting to TSB the record shareholder’s written consent and by dissenting with respect to all the shares of which the shareholder is the beneficial shareholder or over which the shareholder has power to direct the vote.

A shareholder who does not, prior to the special shareholders meeting, deliver to TSB a written notice of the shareholder’s intent to demand payment for the “fair value” of the shares will lose the right to exercise dissenters’ rights. In addition, any shareholder electing to exercise dissenters’ rights must either vote against the merger or abstain from voting.

If the merger is completed, Glacier (as the surviving corporation) will, within 10 days after the effective date of the merger, deliver a written notice to all TSB shareholders who properly gave notice of their intent to exercise dissenters’ rights. The notice will, among other things:

•

supply a form for demanding payment;

•

set a date by which Glacier must receive the payment demand, which date will be between 30 and 60 days after notice is delivered;

•

state Glacier’s estimate of the “fair value” for the shares and the date by which any notice to withdraw (discussed below) must be received; and

•

provide a copy of the dissenters’ rights provisions of the Montana Code Annotated, Sections 35-1-826 through 35-1-839.

A shareholder wishing to exercise dissenters’ rights must at that time file the payment demand and deliver share certificates as required in the notice. Failure to do so will cause that person to lose their dissenters’ rights.

A shareholder who has complied with the requirements summarized in the previous paragraph may nevertheless decline to exercise dissenters’ rights and withdraw from the appraisal process by notifying Glacier by the date set forth in the written notice provided by Glacier following consummation of the merger. If the shareholder does not withdraw from the appraisal process by the specified date, he or she may not do so thereafter unless Glacier consents to such withdrawal in writing.

Upon completion of the merger or receipt of the payment demand, whichever is later, Glacier will pay each dissenter with properly perfected dissenters’ rights Glacier’s estimate of the “fair value” of the shareholder’s shares, plus accrued interest from the effective date of the merger. With respect to a dissenter who did not beneficially own shares of TSB prior to the public announcement of the merger, Glacier is not required to make the payment until the dissenter has agreed to accept the payment in full satisfaction of the dissenter’s demands. “Fair value” means the value of the shares immediately before the effective date of the merger. The “fair value” may be less than, equal to or greater than the value of the consideration that a TSB shareholder would be entitled to receive under the merger agreement. The rate of interest is required to be the rate on judgments in the state of Montana.

Within 30 days of Glacier’s payment (or offer of payment in the case of shares acquired after public announcement of the merger) to a dissenting shareholder, a dissenter dissatisfied with Glacier’s estimate of the fair value may notify Glacier of the dissenter’s own estimate of the fair value and demand payment of that amount. If Glacier does not accept the dissenter’s estimate and the parties do not otherwise settle on a fair value, then Glacier must, within 60 days of receiving the estimate and demand, petition a court to determine the fair value.

In view of the complexity of the Montana statutes governing dissenters’ rights of appraisal, TSB shareholders who wish to dissent from the merger and pursue appraisal rights should consult their legal advisors.

The failure of a TSB shareholder to comply strictly with the Montana statutory requirements will result in a loss of dissenters’ rights. A copy of the relevant statutory provisions is attached as Appendix B. You should refer to Appendix B for a complete statement concerning dissenters’ rights and the foregoing summary of such rights is qualified in its entirety by reference to Appendix B.

Stock Options

The merger agreement provides that at the effective time of the merger, each outstanding and unexercised option to acquire shares of TSB (“TSB Options”), whether or not then vested, will be canceled, and in lieu thereof the holders of such TSB Options will be paid in cash an amount equal to the product of (a) the number of shares of TSB common stock subject to such option, and (b) the amount by which the per-share merger consideration value exceeds the exercise price per share of such TSB Option, net of tax withholding.

Conditions to the Merger

Consummation of the merger is subject to various conditions. No assurance can be provided as to whether these conditions will be satisfied or waived by the appropriate party. Accordingly, there can be no assurance that the merger will be completed.

Certain conditions must be satisfied or events must occur before the parties will be obligated to complete the merger. Each party’s obligations under the merger agreement are conditioned on satisfaction by the other party of conditions applicable to them. Some of these conditions, applicable to the respective obligations of both Glacier and TSB, are as follows:

•

the accuracy of the other party’s representations in the merger agreement and any certificate or other instrument delivered in connection with the merger agreement;

•

compliance by the other party of all material terms, covenants, and conditions of the merger agreement;

•

that there shall have been no damage, destruction, or loss, or other event or sequence of events, that has had or potentially may have a material adverse effect with respect to the other party;

•

that no action or proceeding has been commenced or threatened by any governmental agency to restrain or prohibit or invalidate the merger;

•

the parties shall have agreed on the amount of the TSB Closing Capital and Final Transaction-Related Expenses, each as defined in the merger agreement; and

•

TSB shall have received a fairness opinion from Davidson, and such fairness opinion shall not have been modified or withdrawn; and

•

the registration statement filed with the SEC, required to register the Glacier common stock to be issued to shareholders of TSB, has become effective, and no stop-order suspending such effectiveness has been issued and no proceedings for that purpose have been initiated or threatened by the SEC.

In addition to the above, the obligations of Glacier under the merger agreement are subject to conditions that:

•

in the opinion of the executive officers of TSB, TSB’s allowance for possible loan and lease losses is adequate to absorb its anticipated loan losses;

•

TSB shall have provided to Glacier, upon request, certain reports relating to its loans, other extensions of credit, and other assets that are adversely classified, and neither these reports nor any examination by Glacier will have revealed a change in adversely classified assets or other new information relating to TSB’s loans which constitutes a material adverse effect on TSB; and

•

TSB shall have received, from all holders of outstanding warrants to purchase shares of TSB common stock, warrant termination agreements in form and substance reasonably satisfactory to Glacier.

Additionally, either Glacier or TSB may terminate the merger if certain conditions applicable to the other party are not satisfied or waived. Those conditions are discussed below under “–Termination of the Merger Agreement.”

Either Glacier or TSB may waive any conditions applicable to its obligations, except those that are required by law (such as receipt of regulatory approvals and TSB shareholder approval). Either Glacier or TSB may also grant extended time to the other party to complete an obligation or condition.

Amendment of the Merger Agreement

The merger agreement may be amended upon authorization of the boards of directors of the parties, whether before or after the special meeting of the shareholders of TSB. To the extent permitted under applicable law, the parties may make any amendment or supplement without further approval of TSB shareholders. However, after shareholder approval, any amendments that would reduce the amount or change the form of the consideration that TSB shareholders will receive in the merger would require further TSB shareholder approval.

Termination of the Merger Agreement

The merger agreement contains several provisions entitling either Glacier or TSB to terminate the merger agreement under certain circumstances. The following briefly describes these provisions:

Lapse of Time . If the merger has not been consummated on or before November 30, 2016, then at any time after that date, the board of directors of either Glacier or TSB may terminate the merger agreement and the merger if (i) the terminating party’s board of directors decides to terminate by a majority vote of all if its members, and (ii) the terminating party delivers to the other party written notice that its board of directors has voted in favor of termination.

Mutual Consent . The parties may terminate the merger agreement at any time before closing, whether before or after approval by TSB shareholders, by mutual consent if the board of directors of each party agrees to terminate by a majority vote of all of its members.

Glacier Average Closing Price Greater than $27.05 . By specific action of its board of directors, Glacier may terminate the merger agreement if the Glacier average closing price (as defined in the merger agreement) is greater than $27.05.

If Glacier provides written notice of its intent to terminate the merger agreement because the Glacier average closing price is greater than $27.05, TSB may elect, within three business days of its receipt of such notice, to accept an adjustment to the per-share stock consideration through the issuance of fewer Glacier shares; in such event, the per-share stock consideration will be the number of Glacier shares equal to the quotient obtained by (a) dividing the result of (i) the number of shares of TSB Stock outstanding at the Effective Time, multiplied by (ii) the per-share stock consideration, multiplied by (iii) $27.05 by the Glacier average closing price, and (b) dividing that result by the number of TSB shares outstanding at the closing. If TSB makes the election to accept such decrease in the number of Glacier shares to be issued, no termination of the merger agreement will occur, and the merger agreement will remain in effect in accordance with its terms, except as the per-share stock consideration has been adjusted.

Glacier Average Closing Price Less than Specified Amounts . By specific action of its board of directors, TSB may terminate the merger agreement if the Glacier average closing price is less than certain amounts specified in the merger agreement.

TSB may terminate the merger agreement if the Glacier average closing price is less than $19.99 but not less than $19.00 and during the period from the execution date of the merger agreement to the determination date the price of Glacier common stock has underperformed the KBW Regional Banking Index by more than 10% TSB may also terminate the merger agreement if the Glacier average closing price is less than $19.00 (in such case no reference to the performance of Glacier stock relative to a peer group index would be required).

If TSB provides written notice of its intent to terminate the merger agreement because the Glacier average closing price is less than $19.99 but not less than $19.00 and the price of Glacier stock has underperformed the KBW Regional Banking Index by more than 10%, Glacier may elect, within three business of its receipt of such notice, to adjust the per-share stock consideration (or per-share cash consideration) such that the total value of Glacier stock to be issued (plus any additional cash consideration) is equal to the result of (i) the number of shares of TSB common stock outstanding at the closing of the merger multiplied by (ii) the per-share stock consideration multiplied by (iii) $19.99.

If TSB provides written notice of its intent to terminate the merger agreement because the Glacier average closing price is less than $19.00, Glacier may elect, within three business days of its receipt of such notice, to adjust the per-share stock consideration (or per-share cash consideration) such that the total value of Glacier stock to be issued (plus any additional cash consideration) is equal to the result of (i) the number of shares of TSB common stock outstanding at the closing of the merger multiplied by (ii) the per-share stock consideration multiplied by (iii) $19.00.

If Glacier elects to increase the per-share stock consideration (or per-share cash consideration) as described above, no termination of the merger agreement will occur, and the merger agreement will remain in effect in accordance with its terms, except as the consideration has been adjusted.

No Regulatory Approvals . Either party may terminate the merger agreement if the regulatory approvals required to be obtained are denied, or if any such approval is conditioned on a substantial deviation from the transactions contemplated by the merger agreement, subject to certain rights granted in the merger agreement to appeal the denial of such regulatory approval.

Breach of Representation or Covenant . Either party may terminate the merger agreement (so long as the terminating party is not then in material breach of any of its representations, warranties, covenants or agreements in the merger agreement) if there has been a material breach of any covenants or agreements set forth in the merger agreement by the other party, which is not cured within 30 days following written notice to the party committing such breach, or which breach, by its nature, cannot be cured prior to the closing of the merger.

Failure to Recommend or Obtain Shareholder Approval . Glacier may terminate the merger agreement if the TSB Board (i) fails to recommend to its shareholders approval of the merger, or (ii) modifies, withdraws or changes in a manner adverse to Glacier its recommendation to shareholders to approve the merger. Additionally, regardless of whether or not the TSB Board recommends approval of the merger to its shareholders, Glacier may terminate the merger agreement if TSB shareholders do not to approve the merger agreement.

Impracticability . Either party may terminate the merger agreement upon written notice to the other party if the board of directors of the party seeking termination has determined in its sole judgment, made in good faith and after due consideration and consultation with counsel, that the merger has become inadvisable or impracticable by reason of actions taken by the federal government or the government of the State of Montana to restrain or invalidate the merger or the merger agreement.

Dissenting Shares . Glacier may terminate the merger agreement if holders of 5% or more of the outstanding TSB shares have properly given notice of their intent to assert appraisal rights under Montana law.

Superior Proposal – Termination by TSB . TSB may terminate the merger agreement if its board of directors determines in good faith that TSB has received a “Superior Proposal” as defined in the merger agreement. This right is subject to the requirement that TSB may terminate the merger agreement only if TSB (i) has not breached its covenants regarding the initiation or solicitation of acquisition proposals from third parties; (ii) subsequent to delivering the notice of termination to Glacier, TSB intends to enter into a letter of intent, acquisition agreement or similar agreement relating to such Superior Proposal, (iii) TSB has provided Glacier with at least five days prior written notice that TSB is prepared to accept a Superior Proposal and has given Glacier, if it so elects, an opportunity to amend the terms of the merger agreement (and negotiated with Glacier in good faith with respect to such terms) in such a manner as would enable TSB to proceed with the merger and (iv) simultaneously upon entering into a letter of intent or agreement relating to the Superior Proposal, it delivers to Glacier the break-up fee described below.

Superior Proposal – Termination by Glacier . Glacier may terminate the merger agreement if (i) an “Acquisition Event” (as defined in the merger agreement) has occurred or (ii) a third party has made a proposal to TSB or its shareholders to engage in, or has entered into an agreement with respect to, an Acquisition Event, and the merger agreement and the merger are not approved at the special meeting of TSB shareholders.

Termination Fees

TSB will pay Glacier a termination fee of $250,000 if Glacier terminates the merger agreement based on a TSB breach of its representations or breach of its covenants. Glacier will pay TSB a termination fee of $250,000 if TSB terminates the merger agreement based on a Glacier breach of its representations or breach of its covenants.

Break-Up Fee

If the merger agreement is terminated because (i) the TSB Board fails to recommend shareholder approval of the merger agreement or modifies, withdraws or changes its recommendation in a manner adverse to Glacier; or (ii) TSB terminates the merger agreement after receiving a “Superior Proposal” (as defined in the merger agreement) and Glacier declines the opportunity to amend the terms of the merger agreement to enable the TSB Board to proceed with the merger; or (iii) Glacier terminates the merger agreement if an “Acquisition Event” (as defined in the merger agreement) has occurred, then TSB will immediately pay Glacier a break-up fee of $590,000. If the merger agreement is terminated by Glacier due to the merger agreement not being approved at the TSB special shareholders’ meeting following TSB’s receipt of a proposal to enter into an Acquisition Event, and prior to or within one year after such termination, TSB enters into an agreement, or publicly announces an intention to engage in an Acquisition Event, or within 18 months after such termination an Acquisition Event has occurred, then TSB will promptly pay Glacier the break-up fee of $590,000.

Allocation of Costs Upon Termination

If the merger agreement is terminated (except under circumstances that would require the payment of a termination fee or break-up fee) Glacier and TSB will each pay their own out-of-pocket expenses incurred in connection with the transaction and, except for any applicable termination or break-up fees, will have no other liability to the other party.

Conduct Pending the Merger

The merger agreement provides that, until the merger is effective, TSB will conduct its business only in the ordinary and usual course. The merger agreement also provides that, unless Glacier otherwise consents in writing, and except as required by applicable regulatory authorities, TSB will refrain from engaging in various activities such as:

•

effecting any stock split or other recapitalization with respect to TSB, or pledging or encumbering any shares of TSB stock;

•

other than as permitted by the merger agreement, declaring or paying any dividends, or making any other distributions with respect to shares of TSB;

•

acquiring, selling, transferring assigning or encumbering or otherwise disposing of any material assets having a value greater than $25,000, or making any material commitment other than in the ordinary course of business;

•

soliciting or accepting deposit accounts of a different type from accounts previously accepted by TSB or at rates materially in excess of prevailing interest rates, or, other than as permitted by the merger agreement, incurring any indebtedness for borrowed money;

•

other than as permitted by the merger agreement, offering or making loans or other extensions of credit of a different type, or applying different underwriting standards, from those previously offered or applied by TSB, or offering or making a new loan or extension of credit in an amount greater than $500,000 without prior consultation with Glacier, which consultation will not be unreasonably withheld or delayed and which will be deemed provided if Glacier has not responded to such request within three business days after Glacier’s receipt of a loan package concerning the loan at issue;

•

making any negative provisions to the ALLL or failing to maintain an adequate reserve for loan and lease losses;

•

other than as permitted by the merger agreement, acquiring an ownership or leasehold interest in real property without conducting an appropriate environmental evaluation and providing specified information and notices to Glacier;

•

other than as permitted by the merger agreement, entering into, renewing, amending or terminating any contracts calling for a payment of more than $10,000, with a term of one year or more;

•

other than as permitted by the merger agreement, entering into or amending any contract calling for a payment of more than $10,000, unless the contract may be terminated without cause or penalty upon 30 days’ notice or less;

•

other than as permitted by the merger agreement, entering into any personal services contract;

•

selling any securities other than in the ordinary course of business, or selling any securities even in the ordinary course of business if the aggregate gain or loss realized from all sales after the date of execution of the merger agreement would exceed $25,000, or transferring investment securities between portfolios;

•

other than as permitted by the merger agreement, implementing or adopting any material changes in its operations, policies or procedures;

•

other than in accordance with binding existing commitments, making capital expenditures in excess of $10,000 per project or related series of projects or $25,000 in the aggregate; and

•

entering into material transactions or making any material expenditures other than in the ordinary course of business except for expenses reasonably related to the completion of the merger.

TSB Management and Operations After the Merger

TSB will merge with and into Glacier Bank, and following the merger will operate under Glacier Bank’s division, First Security Bank, as part of that division, consistent with Glacier’s organizational structure.

Employee Benefit Plans

The merger agreement confirms Glacier’s intent that Glacier’s and Glacier Bank’s current personnel policies will apply to any employees of TSB who remain employed following the closing of the merger. Such employees will be eligible to participate in all of the benefit plans of Glacier that are generally available to similarly situated employees of Glacier and/or Glacier Bank. For purposes of such participation, current employees’ prior service with TSB will constitute prior service with Glacier for purposes of determining eligibility and vesting under benefit plans of Glacier and Glacier Bank, including vacation time and participation and benefits under the applicable Glacier or Glacier Bank severance plan for employees in effect at the time of any termination.

Interests of Certain Persons in the Merger

Certain members of the TSB Board and management may be deemed to have interests in the merger, in addition to their interests as shareholders of TSB generally. The TSB Board was aware of these factors and considered them, among other things, in approving the merger agreement.

Stock Ownership . TSB directors, executive officers and their spouses beneficially owned, as of the record date for the special meeting, 370,333 shares of TSB common stock, representing approximately 20.86% of all outstanding shares of TSB common stock. The directors and executive officers of TSB will receive the same consideration in the merger for their shares as other shareholders of TSB.

Voting Agreement . As described above under “—Voting Agreement,” the directors of TSB have entered into a voting agreement, dated as of April 20, 2016. Pursuant to the voting agreement, each signing person agrees to vote the shares of TSB common stock that he owns or controls in favor of the merger.

TSB Director Non-Competition Agreement . Each member of the TSB Board has entered into a non-competition agreement with Glacier and TSB. Except under certain limited circumstances, the non-competition agreement prohibits such directors from becoming involved in a business that competes with Glacier or any of Glacier’s subsidiaries, divisions or affiliates within Missoula, Ravalli or Lake Counties in Montana. The agreement also prohibits the solicitation of Glacier’s employees or customers. The term of the non-competition agreement commences upon the effective date of the merger and continues until two years following the closing of the merger.

Change-in-Control Payments . James Salisbury, President and CEO of TSB, and a TSB director, is a party to an employment agreement with TSB. The employment agreement provides that if TSB should undergo a change in control (as defined in the agreement) during the time the agreement is in effect, TSB will pay Mr. Salisbury additional compensation in the amount of one year’s salary.

Anne Robinson, Chief Financial Officer/Compliance Officer of TSB, and Jason Erickson, Senior Vice President/Chief Lending Officer of TSB, are parties to change-in-control agreements with TSB. The respective agreements provide that in the event of a qualified termination in connection with a change in control (as both such terms are defined in the agreements), the executive is entitled to payment equal to one year’s base salary plus the premium for single rate health insurance coverage for a period of one year or until the executive obtains other coverage, whichever comes first. The agreements state that the executive shall continue employment with TSB’s successor to facilitate a smooth transition.

Employment Agreement . Glacier Bank has entered into an employment agreement with Jason Erickson, Senior Vice President and Chief Lending Officer of TSB. The employment agreement is effective on (and conditioned upon) the closing of the merger, and is for a term of two years. The agreement provides that Mr. Erickson’s title will be Vice President and Commercial Loan Officer for First Security Bank, a division of Glacier Bank. Mr. Erickson will receive an annualized base salary of $96,000 and will be entitled to participate in Glacier Bank’s profit sharing and short- and long-term incentive plans, as well as any group life insurance, disability, health and accident insurance plans, and other employee fringe benefit plans that Glacier or Glacier Bank may have in effect from time to time for similarly situated employees.

If Mr. Erickson’s employment is terminated for Cause or he terminates his employment without Good Reason (as such terms are defined in the agreement), Glacier Bank will pay him the salary earned and expenses reimbursable incurred through the date of termination.

If Mr. Erickson’s employment is terminated without Cause or he terminates his employment with Good Reason, Glacier Bank will pay him a lump sum equal to the lesser of (i) one times his annual base salary at the time of termination, or (ii) the amount of salary remaining to be paid during the term of the agreement. The employment agreement provides that in the event Mr. Erickson is entitled to be paid severance benefits under his change-in-control agreement described above, the change-in-control agreement will govern and he will not be entitled to a payment under his employment agreement,

The employment agreement provides that during his employment and for the lesser of the remaining term of the agreement or one year following the date employment with Glacier Bank has ended, Mr. Erickson will not engage in any competitive activity in Missoula, Ravalli or Lake Counties in Montana, provided that the obligation not to compete will not apply if Mr. Erickson’s employment is terminated without cause. In addition, the employment agreement provides that during his employment and for a period of one year following any termination of his employment, Mr. Erickson will not persuade or entice, or attempt to persuade or entice, any employee of Glacier or Glacier Bank to terminate his or her employment with Glacier or Glacier Bank, or any person or entity to terminate or reduce its business relationship with Glacier or Glacier Bank

Indemnification of Directors and Officers; Insurance . The merger agreement provides that Glacier will, for a period of four years following the closing of the merger, indemnify the present and former directors and officers of TSB against liabilities or costs that may arise in the future, incurred in connection with claims or actions arising out of or pertaining to matters that existed or occurred prior to the effective date of the merger. The scope of this indemnification is to the fullest extent that such persons would have been entitled to indemnification under applicable law and the articles of incorporation or bylaws of TSB, as applicable.

The merger agreement also provides that for a period of four years following the closing of the merger, Glacier will use reasonable best efforts to cause to be maintained in effect, director and officer liability insurance substantially similar to that maintained by Glacier with respect to claims arising from facts or events that occurred before the effective date of the merger.

Regulatory Requirements

Closing of the merger is subject to approval by the appropriate banking regulatory authorities, including the Federal Deposit Insurance Corporation and the Commissioner of the Montana Division of Banking and Financial Institutions.

Material Federal Income Tax Consequences of the Merger

This section describes the anticipated material United States federal income tax consequences of the merger of TSB with and into Glacier Bank, to U.S. holders of TSB common stock who exchange shares of TSB common stock for a combination of shares of Glacier common stock and cash pursuant to the merger.

For purposes of this discussion, a U.S. holder is a beneficial owner of TSB common stock who for United States federal income tax purposes is:

•

a citizen or resident of the United States;

•

a corporation, or an entity treated as a corporation, created or organized in or under the laws of the United States or any state or political subdivision thereof;

•

a trust that (1) is subject to (A) the primary supervision of a court within the United States and (B) the authority of one or more United States persons to control all substantial decisions of the trust or (2) has a valid election in effect under applicable Treasury Regulations to be treated as a United States person; or

•

an estate that is subject to United States federal income tax on its income regardless of its source.

If a partnership (including for this purpose any entity treated as a partnership for United States federal income tax purposes) holds TSB common stock, the tax treatment of a partner generally will depend on the status of the partner and the activities of the partnership. If you are a partner of a partnership holding TSB common stock, you should consult your tax advisor.

This discussion addresses only those TSB shareholders that hold their TSB common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code, and does not address all the United States federal income tax consequences that may be relevant to particular TSB shareholders in light of their individual circumstances or to TSB shareholders that are subject to special rules, such as:

•

financial institutions;

In addition, the discussion does not address any alternative minimum tax or any state, local or foreign tax consequences of the merger.

The following discussion is based on the Internal Revenue Code, its legislative history, existing and proposed regulations thereunder and published rulings and decisions, all as currently in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. Any such change could affect the continuing validity of this discussion.

In connection with the filing of the registration statement of which this document is a part, Garlington, Lohn & Robinson, PLLP, special tax counsel to Glacier, has delivered an opinion to Glacier to the effect that the merger will for federal income tax purposes qualify as a reorganization within the meaning of Internal Revenue Code Section 368(a); and both Glacier and TSB expect to report the merger accordingly on their federal income tax returns. The opinion is based on assumptions, representations, warranties and covenants, including those contained in the merger agreement and in tax representation letters provided by Glacier, Glacier Bank and TSB. The accuracy of such assumptions, representations and warranties, and compliance with such covenants, could affect the conclusions set forth in such opinion. The opinion is not binding on the Internal Revenue Service or the courts. Glacier and TSB have not requested and do not intend to request any ruling from the Internal Revenue Service as to the United States federal income tax consequence of the merger. Accordingly, each TSB shareholder should consult its tax advisor with respect to the particular tax consequences of the merger to such holder.

Tax Consequences of the Merger Generally to Holders of TSB Common Stock. If the merger is a reorganization within the meaning of Section 368(a) of the Internal Revenue Code, the tax consequences are as follows:

•

TSB shareholders will exchange all of their TSB common stock for a combination of Glacier common stock and cash in the merger. Accordingly, holders of TSB common stock will recognize gain in an amount equal to the lesser of (1) the amount by which the sum of the fair market value of the Glacier common stock and cash received by a holder of TSB common stock exceeds such holder’s cost basis in its TSB common stock, and (2) the amount of cash received by such holder of TSB common stock in exchange for such holder’s TSB common stock (except with respect to any cash received instead of fractional share interests in Glacier common stock, as discussed in the section entitled “Cash Received Instead of a Fractional Share of Glacier Common Stock”);

•

a TSB shareholder’s aggregate tax basis in the Glacier common stock received in the merger will be equal to the shareholder’s aggregate tax basis in such shareholder’s TSB common stock surrendered, decreased by the amount of any cash received and increased by the amount of any gain recognized; and

•

the holding period of Glacier common stock received in exchange for shares of TSB common stock will include the holding period of the TSB common stock for which it is exchanged.

If holders of TSB common stock acquired different blocks of TSB common stock at different times or at different prices, any gain or loss will be determined separately with respect to each block of TSB common stock and such holders’ basis and holding period in their shares of Glacier common stock may be determined with reference to each block of TSB common stock. Any such holders should consult their tax advisors regarding the manner in which cash and Glacier common stock received in the exchange should be allocated among different blocks of TSB common stock and with respect to identifying the bases or holding periods of the particular shares of Glacier common stock received in the merger.

Gain that holders of TSB common stock recognize in connection with the merger generally will constitute capital gain and will constitute long-term capital gain if such holders have held (or are treated as having held) their TSB common stock for more than one year as of the date of the merger. Long-term capital gain of non-corporate holders of TSB common stock is generally taxed at preferential rates. In addition such gain may be subject to the 3.8% Unearned Income Medicare Contribution Tax on net investment income. In some cases, if a holder actually or constructively owns Glacier stock other than Glacier stock received pursuant to the merger, the recognized gain could be treated as having the effect of a distribution of a dividend under the tests set forth in Internal Revenue Code Section 302, in which case such gain would be treated as dividend income. Because the possibility of dividend treatment depends primarily upon each holder’s particular circumstances, including the application of the constructive ownership rules, holders of TSB common stock should consult their tax advisors regarding the application of the foregoing rules to their particular circumstances.

Cash Received Instead of a Fractional Share of Glacier Common Stock. A holder of TSB common stock who receives cash instead of a fractional share of Glacier common stock will generally be treated as having received the fractional share pursuant to the merger and then as having that fractional share of Glacier common stock redeemed for cash. As a result, a holder of TSB common stock will generally recognize gain or loss equal to the difference between the amount of cash received in lieu of the fractional share and the basis in his, her or its fractional share interest as set forth above. Except as described above, this gain or loss will generally be capital gain or loss, and will be long-term capital gain or loss if, as of the effective date of the merger, the holding period for such shares is greater than one year. The deductibility of capital losses is subject to limitations.

Backup Withholding and Information Reporting. Payments of cash to a holder of TSB common stock may, under certain circumstances, be subject to information reporting and backup withholding, unless the holder provides proof of an applicable exemption satisfactory to Glacier and the exchange agent or furnishes its taxpayer identification number, and otherwise complies with all applicable requirements of the backup withholding rules. Any amounts withheld from payments to a holder under the backup withholding rules are not additional tax and will be allowed as a refund or credit against the holder’s United States federal income tax liability, provided the required information is furnished to the Internal Revenue Service.

Reporting Requirements. TSB shareholders who are “significant holders” are required to file a statement with their U.S. federal income tax return setting forth certain information, including, but not limited to, their tax basis (determined immediately before the merger) in the TSB common stock exchanged in the merger and the fair market value (determined immediately before the merger) of the TSB common stock exchanged in the merger. For these purposes a “significant holder” is a holder of TSB common stock who immediately before the merger (i) owned at least 5% of the total outstanding stock of TSB by vote or value or (ii) owned stock of TSB with a tax basis of at least $1 million. All TSB shareholders will be required to retain permanent tax records of the basis of TSB common stock exchanged and the Glacier common stock and cash received in the merger.

The preceding discussion is intended only as a summary of material United States federal income tax consequences of the merger. It is not a complete analysis or discussion of all potential tax effects that may be important to you. Thus, you are strongly encouraged to consult your tax advisor as to the specific tax consequences resulting from the merger, including tax return reporting requirements, the applicability and effect of federal, state, local, and other tax laws and the effect of any proposed changes in the tax laws.

Accounting Treatment of the Merger

The acquisition of TSB will be accounted for using the acquisition method of accounting by Glacier under accounting principles generally accepted in the United States of America. Accordingly, using the acquisition method of accounting, the assets and liabilities of TSB will be recorded by Glacier at their respective fair values at the time of the merger. The excess of Glacier’s purchase price over the net fair value of assets acquired including identifiable intangible assets and liabilities assumed will be recorded as goodwill. Goodwill will be periodically assessed for impairment but no less frequently than on an annual basis. Prior period financial statements are not restated and results of operation of TSB will be included in Glacier’s consolidated statement of operations after the date of the merger. The identifiable intangible assets with finite lives, other than goodwill, will be amortized against the combined company’s earnings following completion of the merger.

Competition

TSB experiences competition in both lending and attracting funds from other commercial banks, savings banks, savings and loan associations, credit unions, finance companies, pension trusts, mutual funds, insurance companies, mortgage bankers and brokers, brokerage and investment banking firms, asset-based non-bank lenders, government agencies and certain other non-financial institutions, including retail stores, which may offer more favorable financing alternatives than TSB.

TSB also competes with companies located outside of its primary market that provide financial services to persons within this market. Some of TSB’s current and potential competitors have larger customer bases, greater brand recognition, and significantly greater financial, marketing and other resources than TSB and some of them are not subject to the same degree of regulation as TSB.

Employees

As of March 31, 2016, TSB had 17 full-time and 4 part-time employees. TSB believes that it has a good relationship with its employees and the employees are not represented by a collective bargaining agreement.

Properties

TSB owns and operates out of a commercial building built in 2008 at 3660 Mullan Road in Missoula, Montana.

Legal Proceedings

From time to time, litigation arises in the normal conduct of TSB’s business. TSB, however, is not currently involved in any litigation that management of TSB believes, either individually or in the aggregate, could reasonably be expected to have a material adverse effect on its business, financial condition or results of operations.

DESCRIPTION OF GLACIER’S CAPITAL STOCK

Glacier’s authorized capital stock consists of 117,187,500 shares of common stock, $0.01 par value per share, and 1,000,000 shares of preferred stock, $0.01 par value per share. As of the date of this proxy statement/prospectus, Glacier had no shares of preferred stock issued. The Glacier board of directors is authorized, without further shareholder action, to issue preferred stock shares with such designations, preferences and rights as the Glacier board of directors may determine.

Glacier common stock is listed for trading on The NASDAQ Global Select Market under the symbol “GBCI.”

Glacier’s shareholders do not have preemptive rights to subscribe to any additional securities that may be issued. Each share of Glacier common stock has the same relative rights and is identical in all respects to every other share of Glacier common stock. If Glacier is liquidated, the holders of Glacier common stock are entitled to share, on a pro rata basis, Glacier’s remaining assets after provision for liabilities.

For additional information concerning Glacier’s capital stock, see “Comparison of Certain Rights of Holders of Glacier and TSB Common Stock” below.

COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF

GLACIER AND TSB COMMON STOCK

Montana law and Glacier’s articles of incorporation and bylaws govern the rights of Glacier’s shareholders and will govern the rights of TSB’s shareholders, who will become shareholders of Glacier as a result of the merger. The rights of TSB’s shareholders are currently governed by Montana law and by TSB’s articles of incorporation and bylaws. The following is a brief summary of certain differences between the rights of Glacier and TSB shareholders. This summary is not intended to provide a comprehensive discussion of each company’s governing documents. This summary is qualified by the documents referenced and the laws of Montana. See also “Where You Can Find More Information About Glacier.”

General

Under its articles of incorporation, Glacier’s authorized capital stock consists of 117,187,500 shares of common stock, $0.01 par value per share, and 1,000,000 shares of preferred stock, $0.01 par value per share. No shares of preferred stock are currently outstanding.

Under its articles of incorporation, TSB’s authorized capital consists of 5,000,000 shares of common stock, par value $0.01 per share, and 1,000,000 shares of preferred stock. No shares of preferred stock are currently outstanding.

The following is a more detailed description of Glacier’s and TSB’s capital stock.

Common Stock

As of March 31, 2016, there were 76,168,388 shares of Glacier common stock issued and outstanding, in addition to 232,202 shares of unvested restricted stock awards, under Glacier’s employee and director equity compensation plans.

As of March 31, 2016, there were 1,740,951 shares of TSB common stock issued and outstanding, in addition to options for the purchase of 34,344 shares of TSB common stock.

Preferred Stock

As of the date of this proxy statement/prospectus, Glacier had no shares of preferred stock issued. The Glacier board of directors is authorized, without further shareholder action, to issue preferred stock shares with such designations, preferences and rights as the Glacier board of directors may determine.

As of the date of this proxy statement/prospectus, TSB had no shares of preferred stock issued. The TSB Board is authorized, without further shareholder action, to issue preferred stock shares with such designations, preferences and rights as the TSB Board may determine.

Dividend Rights

Dividends may be paid on Glacier common stock as and when declared by the Glacier board of directors out of funds legally available for the payment of dividends. The Glacier board of directors may issue preferred stock that is entitled to such dividend rights as the board of directors may determine, including priority over the common stock in the payment of dividends.

The ability of Glacier to pay dividends basically depends on the amount of dividends paid to it by its subsidiaries. The payment of dividends is subject to government regulation, in that regulatory authorities may prohibit banks and bank holding companies from paying dividends in a manner that would constitute an unsafe or unsound banking practice. In addition, a bank may not pay cash dividends if doing so would reduce the amount of its capital below that necessary to meet minimum applicable regulatory capital requirements. State laws also limit a bank’s ability to pay dividends. Accordingly, the dividend restrictions imposed on the subsidiaries by statute or regulation effectively may limit the amount of dividends Glacier can pay.

Dividends may be paid on TSB common stock as and when declared by the TSB Board out of funds legally available for the payment of dividends. TSB’s payment of dividends is generally subject to the same considerations described above with respect to Glacier, except that TSB has no subsidiaries and thus funds legally available for the payment of dividends are generated by TSB’s operations.

Voting Rights

All voting rights are currently vested in the holders of Glacier common stock and TSB common stock, with each share being entitled to one vote.

The articles of incorporation of Glacier provide that shareholders do not have cumulative voting rights in the election of directors. The articles of incorporation of TSB provide that shareholders do not have cumulative voting rights in the election of directors.

Preemptive Rights

Neither Glacier’s nor TSB’s shareholders have preemptive rights to subscribe to any additional securities that may be issued.

Liquidation Rights

If Glacier is liquidated, the holders of Glacier common stock are entitled to share, on a pro rata basis, Glacier’s remaining assets after provision for liabilities. The Glacier board of directors is authorized to determine the liquidation rights of any preferred stock that may be issued.

If TSB is liquidated, the holders of TSB common stock are entitled to share, on a pro rata basis, TSB’s remaining assets after provision for liabilities.

Assessments

All outstanding shares of Glacier common stock are, and the shares to be issued in the merger will be, fully paid and nonassessable. Shares of TSB common stock are fully paid and nonassessable.

Amendment of Articles and Bylaws

The Montana Business Corporation Act (“MBCA”) authorizes a corporation’s board of directors to make various changes of an administrative nature to its articles of incorporation. Other amendments to a corporation’s articles of incorporation must be recommended to the shareholders by the board of directors, unless the board determines that because of a conflict of interest or other special circumstances it should make no recommendation, and must be approved by a majority of all votes entitled to be cast by each voting group that has a right to vote on the amendment. The Glacier board of directors may, by a majority vote, amend Glacier’s bylaws. The bylaws may also be amended by the holders of a majority of votes cast at an annual or special meeting of shareholders.

The MBCA applies to TSB’s ability to amend its articles of incorporation in the manner described above. The TSB Board may amend or repeal TSB’s bylaws, or adopted new bylaws; however, any bylaws, or any alteration, amendment or repeal of the bylaws, may be subsequently changed or repealed by the holders of a majority of the stock entitled to vote at any shareholders meeting. The bylaws may also be amended or repealed by the shareholders at any regular or special shareholders meeting.

Board of Directors - Number of Directors

Glacier’s articles of incorporation provide that the number of directors may not be less than 7 or more than 17. Glacier’s board currently consists of 10 members, each of whom is currently serving an annual term.

TSB’s articles of incorporation provide that the number of directors may not be less than 7 or more than 12. TSB’s board currently consists of 7 members, each of whom is serving an annual term.

Indemnification and Limitation of Liability

Under the MBCA, indemnification of directors and officers is authorized to cover judgments, amounts paid in settlement, and expenses arising out of actions where the director or officer acted in good faith and in or not opposed to the best interests of the corporation, and in criminal cases, where the director or officer had no reasonable cause to believe that his or her conduct was unlawful. Unless limited by the corporation’s articles of incorporation, Montana law requires indemnification if the director or officer is wholly successful on the merits of the action. Glacier’s bylaws provide that Glacier shall indemnify its directors and officers to the fullest extent not prohibited by law, including

indemnification for payments in settlement of actions brought against a director or officer in the name of the corporation, commonly referred to as a derivative action. Under the MBCA, any indemnification of a director in a derivative action must be reported to shareholders in writing prior to the next annual meeting of shareholders.

Glacier’s articles of incorporation provide that the personal liability of directors and officers for monetary damages shall be eliminated to the full extent permitted by the MBCA.

The indemnification of TSB directors and officers pursuant to its articles of incorporation and bylaw is substantially similar to that described with respect to Glacier above. TSB’s articles of incorporation provide that the personal liability of directors and officers shall be eliminated to the fullest extent permitted by the MBCA and the Montana Bank Act.

Potential “Anti-Takeover” Provisions

Glacier’s articles of incorporation contain a provision requiring that specified transactions with an “interested shareholder” be approved by 80% of the voting power of the then outstanding shares unless it is (i) approved by Glacier’s board of directors, or (ii) certain price and procedural requirements are satisfied. An “interested shareholder” is broadly defined to include the right, directly or indirectly, to acquire or to control the voting or disposition of 10% or more of Glacier’s voting stock.

In addition, the authorization of preferred stock, which is intended primarily as a financing tool and not as a defensive measure against takeovers, may potentially be used by management to make more difficult uninvited attempts to acquire control of Glacier (for example, by diluting the ownership interest of a substantial shareholder, increasing the amount of consideration necessary for shareholder to obtain control, or selling authorized but unissued shares to friendly third parties).

The “supermajority” approval requirement for certain business transactions and the availability of Glacier’s preferred stock for issuance without shareholder approval, may have the effect of lengthening the time required for a person to acquire control of Glacier through a tender offer, proxy contest or otherwise, and may deter any potentially unfriendly offers or other efforts to obtain control of Glacier. This could deprive Glacier’s shareholders of opportunities to realize a premium for their Glacier common stock, even in circumstances where such action was favored by a majority of Glacier’s shareholders.

TSB’s articles of incorporation provide that in the event the board of directors is presented with a possible tender offer or merger or consolidation with another corporation or a purchase of substantially all of the assets of TSB, the board may give, but shall not be required to give, in determining what is in the best interests of TSB and its shareholders, consideration of the social and economic effects on the employees and customers of TSB, and the communities in which TSB’s facilities are located and which TSB serves, in addition to any other factors deemed relevant.

CERTAIN LEGAL MATTERS

The validity of the Glacier common stock to be issued in the merger will be passed upon for Glacier by its special counsel, Moore, Cockrell, Goicoechea & Johnson, P.C, Kalispell, Montana.

(5) “Interest” means interest from the effective date of the corporate action until the date of payment at the average rate currently paid by the corporation on its principal bank loans or, if the corporation has no loans, at a rate that is fair and equitable under all the circumstances.

(6) “Record shareholder” means the person in whose name shares are registered in the records of a corporation or the beneficial shareholder to the extent of the rights granted by a nominee certificate on file with a corporation.

(7) “Shareholder” means the record shareholder or the beneficial shareholder.

35-1-827. Right to dissent . (1) A shareholder is entitled to dissent from and obtain payment of the fair value of the shareholder’s shares in the event of any of the following corporate actions:

B - 1

(d) an amendment of the articles of incorporation that materially and adversely affects rights in respect of a dissenter’s shares because it:

(i) alters or abolishes a preferential right of the shares;

(ii) creates, alters, or abolishes a right in respect of redemption, including a provision with respect to a sinking fund for the redemption or repurchase of the shares;

(2) A beneficial shareholder may assert dissenters’ rights as to shares held on the beneficial shareholder’s behalf only if the beneficial shareholder:

(a) submits to the corporation the record shareholder’s written consent to the dissent not later than the time the beneficial shareholder asserts dissenters’ rights; and

(2) The shareholder who demands payment and deposits the shareholder’s certificates under subsection (1) retains all other rights of a shareholder until these rights are canceled or modified by the taking of the proposed corporate action.

(2) The corporation shall commence the proceeding in the district court of the county where a corporation’s principal office is located or, if its principal office is not located in this state, in Lewis and Clark County. If the corporation is a foreign corporation, it shall commence the proceeding in the county in this state where the principal office of the domestic corporation merged with or whose shares were acquired by the foreign corporation was located or, if the domestic corporation did not have its principal office in the state at the time of the transaction, in Lewis and Clark County.

(3) The corporation shall make all dissenters whose demands remain unsettled, whether or not residents of this state, parties to the proceeding as in an action against their shares, and all parties must be served with a copy of the petition. Nonresidents may be served by certified mail or by publication as provided by law.

(4) The jurisdiction of the district court in which the proceeding is commenced under subsection (2) is plenary and exclusive. The court may appoint one or more persons as appraisers to receive evidence and recommend decision on the question of fair value.

(5) Each dissenter made a party to the proceeding is entitled to judgment:

(a) for the amount, if any, by which the court finds the fair value of the dissenter’s shares plus interest exceeds the amount paid by the corporation; or

(b) for the fair value plus accrued interest of the dissenter’s after-acquired shares for which the corporation elected to withhold payment under 35-1-836.

35-1-839. Court costs and attorney fees . (1) The court in an appraisal proceeding commenced under 35-1-838 shall determine all costs of the proceeding, including the reasonable compensation and expenses of appraisers appointed by the court. The court shall assess the costs against the corporation, except that the court may assess costs against all or some of the dissenters, in amounts the court finds equitable, to the extent the court finds dissenters acted arbitrarily, vexatiously, or not in good faith in demanding payment under 35-1-837.

(2) The court may also assess the fees and expenses of counsel and experts for the respective parties, in amounts the court finds equitable:

(a) against the corporation and in favor of any or all dissenters if the court finds the corporation did not substantially comply with the requirements of 35-1-829 through 35-1-837; or

(b) against either the corporation or a dissenter, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by 35-1-826 through 35-1-839.

(3) If the court finds that the services of counsel for any dissenter were of substantial benefit to other dissenters similarly situated and that the fees for those services should not be assessed against the corporation, the court may award the counsel reasonable attorney fees to be paid out of the amounts awarded the dissenters who were benefited.

Members of the Board:

We understand that Treasure State Bank (“Treasure State”) proposes to enter into an Agreement and Plan of Merger to be dated April 20, 2016 (the “Agreement”) with Glacier Bancorp, Inc. (“GBCI”), pursuant to which, among other things, GBCI will acquire all of the issued and outstanding common stock of Treasure State and then Treasure State will merge with and into Glacier Bank (the “Merger”). As set forth in the Agreement, GBCI will pay each a unit for each share of Treasure State stock outstanding of (i) $1.9570 in cash and (ii) 0.2030 shares of GBCI common stock. The value of that unit that will be paid for each common share outstanding of Treasure State common stock is defined in the Agreement as the Per Share Consideration Value. The cash portion of the merger consideration is subject to the certain adjustments pursuant to Sections 1.2, and 4.15 of the Agreement, as to which we express no opinion. You have advised us that the Merger will qualify as a tax-free reorganization for U.S. federal income tax purposes. The terms and conditions of the Merger are more fully set forth in the Agreement.

Capitalized terms used herein without definition have the respective meanings ascribed to them in the Agreement.

You have requested our opinion as to the fairness, from a financial point of view, to the holders of Treasure State Common Stock of the Per Share Consideration Value to be paid to each such holder in the proposed Merger.

In connection with preparing our opinion, we have reviewed, among other things:

(i)

drafts of the Agreement (including disclosure schedules) and Voting Agreement as of April 9, 2016;

(xi)

such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant, including discussions with management and other representatives and advisors of Treasure State concerning the business, financial condition, results of operations and prospects of Treasure State.

In arriving at our opinion, we have, with your consent, assumed and relied upon the accuracy and completeness of all information that was publicly available or supplied or otherwise made available to, discussed with or reviewed by or for us. We have not independently verified (nor have we assumed responsibility for independently verifying) such information or its accuracy or completeness. We have not undertaken or been provided with any independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of Treasure State, and we did not make an independent appraisal or analysis of Treasure State with respect to the Merger. In addition, we have not assumed any obligation to conduct, nor have we conducted, any physical inspection of the properties or facilities of Treasure State, and have not been provided with any reports of such physical inspections. We have assumed that there has been no material change in Treasure State’s business, assets, financial condition, results of operations, cash flows or prospects since the date of the most recent financial statements provided to us, and that neither Treasure State nor GBCI is party to any material pending transaction, including without limitation any financing, recapitalization, acquisition or merger, divestiture or spin-off, other than the Merger.

With respect to the financial forecasts and other analyses provided to or otherwise reviewed by or for or discussed with us, we have been advised by management of Treasure State, and have assumed with your consent, that such forecasts and other analyses were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of management of Treasure State as to the future financial performance of Treasure State and the other matters covered thereby, and that the financial results reflected in such forecasts and analyses will be realized in the amounts and at the times projected. We assume no responsibility for and express no opinion as to these forecasts and analyses or the assumptions on which they were based. We have relied on the assurances of management of Treasure State that they are not aware of any facts or circumstances that would make any of such information, forecasts or analyses inaccurate or misleading.

We are not experts in the evaluation of loan and lease portfolios, classified loans or other real estate owned or in assessing the adequacy of the allowance for loan losses with respect thereto, and we did not make an independent evaluation or appraisal thereof, or of any other specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Treasure State or GBCI or any of their respective subsidiaries. We have not reviewed any individual loan or credit files relating to Treasure State or GBCI. We have assumed, with your consent, that the respective allowances for loan and lease losses for both Treasure State and GBCI are adequate to cover such losses and will be adequate on a pro forma

C-2

basis for the combined entity.

Our opinion is limited to the fairness, from a financial point of view, of the Per Share Consideration Value to be paid to the holders of Treasure State Common Stock in the proposed Merger. We do not express any view on, and our opinion does not address, any other term or aspect of the Agreement or Merger (including, without limitation, the form or structure of the Merger) or any term or aspect of any other agreement or instrument contemplated by the Agreement or entered into in connection with the Merger, including the fairness of the Merger to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors or other constituencies of Treasure State, or as to the underlying decision by Treasure State to engage in the Merger.

We have acted as Treasure State’s financial advisor in connection with the Merger and will receive a fee for our services, a portion of which is payable upon the rendering of this opinion and a significant portion of which is contingent upon consummation of the Merger. In addition, Treasure State has agreed to reimburse our reasonable expenses and indemnify us against certain liabilities arising out of our engagement.

We may seek to provide investment banking or other financial services to Treasure State or GBCI and its affiliates in the future for which we would expect to receive compensation.
