LOGOLOGO

MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear Northwest Bancorporation, Inc.Idaho Independent Bank Shareholder:

On April 25,October 11, 2018, First Interstate BancSystem, Inc. (which we refer to as “First Interstate”), First Interstate Bank and Northwest Bancorporation, Inc.Idaho Independent Bank (which we refer to as “Northwest”“IIBK”) entered into an Agreement and Plan of Merger (which we refer to as the “merger agreement”) under which NorthwestIIBK will merge with and into First Interstate Bank, with First Interstate Bank remaining as the surviving entity. This transaction is referred to in this document as the “merger.” FollowingBefore the merger Inland Northwest Bank, the wholly-owned subsidiary of Northwest, will merge with and into First Interstate Bank, the wholly-owned subsidiary of First Interstate, with First Interstate Bank as the surviving entity. This transaction is referred to in this document as the “bank merger.” Before we complete the merger,can be completed, the shareholders of NorthwestIIBK must approve the merger agreement.

If the merger is completed, NorthwestIIBK shareholders will be entitled to receive for each share of Northwest common stock they own, 0.5160.50 shares of First Interstate Class A common stock.stock for each share of IIBK common stock they own. The maximum number of shares of First Interstate Class A common stock estimated to be issuable upon completion of the merger is 3,982,842.4,045,302. Based on First Interstate’s closing price of $40.10$44.62 on April 25,October 11, 2018, which was the last trading date preceding the public announcement of the proposed merger, each share of NorthwestIIBK common stock exchanged for 0.5160.50 shares of First Interstate Class A common stock would have a value of $20.69,$22.31, or approximately $159.7$180.5 million in the aggregate. Based on First Interstate’s closing price of $[●]$37.90 on [●], 2018,January 14, 2019, which is the most recent practicable trading day before the printing of this document, each share of NorthwestIIBK common stock exchanged for 0.5160.50 shares of First Interstate Class A common stock would have a value of $[●].$18.95. The common stock of First Interstate trades on the Nasdaq Global Select Market under the symbol “FIBK.” The common stock of NorthwestIIBK trades on the OTC Market’s Pink MarketplaceMarket Place under the symbol “NBCT.“IIBK.” The market price of both First Interstate Class A common stock and NorthwestIIBK common stock will fluctuate before the completion of the merger; therefore,merger. Therefore, you are urged to obtain current market quotations for First Interstate Class A common stock and NorthwestIIBK common stock.

Although the number of shares of First Interstate Class A common stock that holders of NorthwestIIBK common stock will be entitled to receive is fixed, the market value of the stock consideration will fluctuate with the market price of First Interstate Class A common stock and will not be known at the time NorthwestIIBK shareholders vote on the merger. However, NorthwestIIBK has the right to terminate the merger agreement if, at any time during afive-day period commencing on the fifth day before closing, the average closing price of First Interstate Class A common stock over the 20 consecutive trading days ending on and including the fifth day before closing (1) is less than $32.00$36.54 and (2) underperforms the KBW Regional Banking Index by more than 20% during the same time period. If NorthwestIIBK elects to exercise this termination right, then First Interstate has the option to increase the exchange ratio to a level that would eliminate the effectsability of IIBK to terminate the two requirements of this termination right.merger agreement.

The affirmative vote oftwo-thirds a majority of the votes cast at a meeting at which a quorum consisting of at least a majority of the outstanding shares of NorthwestIIBK common stock is present is required to approve the merger agreement. NorthwestIIBK shareholders will vote to adopt the merger agreement at a special meeting of shareholders to be held at [●]:[●] [●].m.9:30 a.m., local time,Pacific Time, on [●], 2018March 27, 2019 at the Airway Heights branchcorporate office of Inland Northwest BankIIBK located at 11917 West Sunset Highway, Airway Heights, Washington.1260 W.

You are also being asked to vote on a proposal to adjourn the shareholder meeting to a later date or dates, if necessary, to permit the further solicitation of proxies if there are not sufficient votes at the meeting to approve the merger agreement (which we refer to as the “Northwest“IIBK adjournment proposal”).

 

Q:

WHAT VOTE DOES NORTHWEST’SIIBK’S BOARD OF DIRECTORS RECOMMEND?

 

A:Northwest’s

IIBK’s board of directors has determined that the proposed merger is in the best interests of NorthwestIIBK shareholders, has unanimously approved the merger agreement and unanimously recommends that NorthwestIIBK shareholders vote “FOR” the approval of the merger agreement and “FOR” the NorthwestIIBK adjournment proposal. See the section entitled “Description of the Merger—Northwest’sIIBK’s Reasons for the Merger and Recommendation of the Board of Directors” beginning on page 33 of this document.

 

Q:

WHAT WILL NORTHWESTIIBK SHAREHOLDERS RECEIVE IN THE MERGER?

 

A:

If the merger is completed, NorthwestIIBK shareholders will receive 0.5160.50 shares of First Interstate Class A common stock (which we refer to as the “merger consideration”) for each share of NorthwestIIBK common stock held immediately before the merger.

Q:

WHAT HAPPENS IF I AM ELIGIBLE TO RECEIVE A FRACTION OF A SHARE OF FIRST INTERSTATE CLASS A COMMON STOCK AS PART OF THE MERGER CONSIDERATION?

A:

First Interstate will not issue any fractional shares of First Interstate Class A common stock in the merger. If the aggregate number of shares of First Interstate Class A common stock that you are entitled to receive as part of the merger consideration includes a fraction of a share of First Interstate Class A common stock, you

will receive cash instead of that fractional share. First Interstate will pay to each former NorthwestIIBK shareholder who holds fractional shares an amount in cash determined by multiplying the average of the closing sale prices of First Interstate Class A common stock for the 20 consecutive trading days ending on and including the fifth day preceding the closing date of the merger, which we refer to as the “average closing price,” by the fraction of a share (rounded to the nearest cent) of First Interstate Class A common stock that such shareholder would otherwise be entitled to receive. See the section entitled “Description of the MergerConsideration to be Received in the Merger” beginning on page 28 of this document.

Q:

HOW WILL THE MERGER AFFECT NORTHWEST EQUITY AWARDS?IIBK STOCK OPTIONS?

 

A:Northwest equity awards

At the effective time of the merger, each outstanding IIBK stock option, whether or not vested, will be affected as follows:

Stock Purchase Warrants: At the effective time of the merger, each warrant to purchase shares of Northwest common stock outstanding immediately before the effective time of the merger, whether or not vested, will be canceled and, upon First Interstate’s receipt of a warrant termination agreement from the holder, exchanged for aconverted into the right to receive cash payment equal to the product of (1) the number of shares of Northwest common stock subject to the warrant multiplied by (2) the amount by which the product of (1) the number of shares of IIBK common stock subject to the stock option and (2) the amount by which the value of the merger consideration exceeds the exercise price. For purposes of this calculation, the value of the merger consideration is the product of 0.50 and the average closing price and the exchange ratio exceeds the exercise price of such warrant, less applicable withholding taxes.

Restricted Stock Awards: At the effective time of the merger, each outstanding share of restricted stock will vest and be converted into the right to receive 0.516 shares of First Interstate Class A common stock.

 

Q:

FIRST INTERSTATE AND FIRST INTERSTATE BANK ARE ALSO ACQUIRING COMMUNITY 1ST BANK, SIMULTANEOUSLY WITH THE MERGER. WHAT IMPACT WILL THE COMMUNITY 1ST BANK MERGER HAVE ON FIRST INTERSTATE’S AND FIRST INTERSTATE BANK’S MERGER WITH IIBK?

A:

First Interstate and First Interstate Bank entered into a merger agreement to acquire Community 1st Bank (“CMYF”) on the same date that it entered into the merger agreement with IIBK. The completion of IIBK’s merger is not conditioned upon or subject to the completion of the merger with CMYF (the “CMYF Merger”). However, since First Interstate and First Interstate Bank will be required to obtain the necessary regulatory approvals for two transactions rather than one, it is possible that the CMYF Merger will lengthen the amount of time that would otherwise be needed to obtain all regulatory approvals of the merger if IIBK were the only banking institution being acquired by First Interstate and First Interstate Bank. See “Risk Factors—Risks Related to the Merger—First Interstate and First Interstate Bank are also acquiring CMYF in the CMYF Merger and the conditions to completing that merger may result in delays in completing the IIBK merger, or make it more difficult or time consuming than expected” for a discussion of the impact that the CMYF acquisition would have on First Interstate’s and First Interstate Bank’s business and operations if both the IIBK and CMYF acquisitions are completed.

Q:

WHAT EQUITY STAKE WILL NORTHWESTIIBK SHAREHOLDERS HOLD IN FIRST INTERSTATE IMMEDIATELY FOLLOWING THE MERGER?

a financial point of view, to the holders of NorthwestIIBK common stock.

Davidson’s opinion, the underlying business decision of the NorthwestIIBK board of directors to engage in the merger or enter into the merger agreement or constitute a recommendation to the NorthwestIIBK board of directors in connection with the merger, and it does not constitute a recommendation to any holder of NorthwestIIBK common stock as to how to vote in connection with the merger or any other matter.

Terminating the Merger Agreement (page 72)67)

The merger agreement may be terminated by mutual written consent of First Interstate and NorthwestIIBK at any time before the completion of the merger. Additionally, subject to conditions and circumstances described in the merger agreement, either First Interstate or NorthwestIIBK may terminate the merger agreement if, among other things, any of the following occur:

 

Northwest

IIBK shareholders do not approve the merger agreement at the NorthwestIIBK special meeting (in the case of NorthwestIIBK terminating, only if NorthwestIIBK has complied with certain obligations, including calling the NorthwestIIBK special meeting and recommending that the NorthwestIIBK shareholders approve the merger);

 

any required regulatory approval has been denied and such denial has become final andnon-appealable, or a governmental authority or court has issued a final, unappealable order prohibiting consummation of the transactions contemplated by the merger agreement;

 

the merger has not been consummated by JanuaryMay 31, 2019, unless the failure to complete the merger by that time was due to the failure of the party seeking to terminate the merger agreement to perform or observe the covenants and agreements provided in the merger agreement; or

 

there is a breach by the other party of any covenant or agreement contained in the merger agreement, or any representation or warranty of the other party becomes untrue, in each case such that the conditions to closing would not be satisfied and such breach or untrue representation or warranty has not been or cannot be cured within 30 days after the giving of written notice to such party of such breach.

First Interstate may also terminate the merger agreement if NorthwestIIBK breaches its obligations in any material respect regarding the solicitation of other acquisition proposals or submission of the merger agreement to Northwest’sIIBK’s shareholders or if the NorthwestIIBK board of directors does not publicly recommend in this document that NorthwestIIBK shareholders approve the merger agreement or withdraws or revises its recommendation in a manner adverse to First Interstate.

NorthwestIIBK may also terminate the merger agreement:

 

before adoption and approval of the merger agreement by its shareholders, to enter into an agreement with respect to a superior proposal to be acquired by a third party, but only if Northwest’sIIBK’s board of directors has determined in good faith based on the advice of legal counsel that failure to take such action would cause the NorthwestIIBK board of directors to violate its fiduciary duties and NorthwestIIBK has not breached its obligations regarding the solicitation of other acquisition proposals; and



within thefive-day period commencing with the fifth day before the closing date of the merger (which we refer to as the “determination date”), if both of the following conditions have been satisfied:

 

the average daily closing sale prices of a share of First Interstate Class A common stock as reported on the Nasdaq Global Select Market for the 20 consecutive trading days ending on and including the determination date is less than $32.00 (80% of the closing sale price of First Interstate Class A common stock on the last trading date before the date of the first public announcement of the merger agreement); and



including the determination date is less than $36.54 (80% of the closing sale price of First Interstate Class A common stock on the third trading date before the date of the first public announcement of the merger agreement); and

 

First Interstate Class A common stock underperforms the KBW Regional Banking Index by more than 20% during the same period.

However, if NorthwestIIBK chooses to exercise this termination right, First Interstate has the option, within five days of receipt of notice from Northwest,IIBK, to adjust the merger consideration and prevent termination under this provision.

Termination Fee (page 73)68)

Under certain circumstances described in the merger agreement in connection with the termination of the merger agreement, including circumstances involving alternative acquisition proposals with respect to NorthwestIIBK and changes in the recommendation of the NorthwestIIBK board of directors to its shareholders, NorthwestIIBK will owe First Interstate a $5.1$6.8 million termination fee. See “Description of the Merger—Termination Fee” for a description of the circumstances under which the termination fee is payable. The termination fee could discourage other companies from seeking to acquire Northwest.IIBK.

Accounting Treatment of the Merger (page 56)50)

The merger will be accounted for using the acquisition method in accordance with U.S. generally accepted accounting principles.

Comparison of Rights of Shareholders (page 81)75)

When the merger is completed, NorthwestIIBK shareholders will receive shares of First Interstate Class A common stock and become First Interstate shareholders with their rights governed by Montana law and by First Interstate’s amended and restated articles of incorporation and bylaws. The rights of NorthwestIIBK shareholders will change as a result of the merger due to differences in First Interstate’s and Northwest’sIIBK’s governing documents. See “Comparison of Rights of Shareholders” for a summary of the material differences between the respective rights of NorthwestIIBK shareholders and First Interstate shareholders.

Material U.S. Federal Income Tax Consequences of the Merger (page 56)50)

The merger is intended to qualify for U.S federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code. Accordingly, U.S. holders of NorthwestIIBK common stock generally will not recognize any gain or loss on the exchange of shares of NorthwestIIBK common stock for shares of First Interstate Class A common stock. However, a U.S. holder of NorthwestIIBK common stock generally will recognize gain or loss with respect to cash received instead of a fractional share of First Interstate Class A common stock that a U.S. holder would otherwise be entitled to receive.

This tax treatment may not apply to all NorthwestIIBK shareholders. Determining the actual tax consequences of the merger to you can be complicated and will depend on your particular circumstances. NorthwestIIBK shareholders should consult their own tax advisor for a full understanding of the merger’s tax consequences that are particular to each shareholder.



To review the tax consequences of the merger to NorthwestIIBK shareholders in greater detail, please see the section “Description of the Merger—Material U.S. Federal Income Tax Consequences of the Merger.”



Risk Factors (page 14)15)

You should consider all the information contained in or incorporated by reference into this document in deciding how to vote for the proposals presented in the document. In particular, you should consider the factors described under “Risk Factors.”



RISK FACTORS

In deciding how to vote, you should consider carefully all of the information included in this document and its annexes, all of the information incorporated by reference into the document and the risk factors identified by First Interstate with respect to First Interstate’s operations included in its filings with the SEC, including First Interstate’s Annual Report onForm 10-K for the year ended December 31, 2017. See “Where You Can Find More Information.” In addition, you should consider the following risk factors.

Risks Related to the Merger

Because the price of First Interstate Class A common stock will fluctuate, NorthwestIIBK shareholders cannot be certain of the market value of the merger consideration.

Upon the completion of the merger, each share of NorthwestIIBK common stock outstanding immediately before the completion of the merger will be converted into the right to receive 0.5160.50 shares of First Interstate Class A common stock. The market value of the merger consideration may vary from the closing price of First Interstate Class A common stock on the date the execution of the merger agreement was announced, on the date that this document was mailed to NorthwestIIBK shareholders, on the date of the NorthwestIIBK special meeting and on the date the merger is completed. The market price of First Interstate Class A common stock may fluctuate as a result of a variety of factors, including general market and economic conditions, changes in First Interstate’s business, operations and prospects, and regulatory considerations. Therefore, at the time of the NorthwestIIBK special meeting, NorthwestIIBK shareholders will not know or be able to calculate the market value of the First Interstate Class A common stock they will receive upon completion of the merger. For example, based on the range of closing prices of First Interstate Class A common stock during the period from April 25,October 11, 2018, the last trading day before public announcement of the merger, through [●], 2018,January 14, 2019, the last practicable date before the date of this document, the merger consideration represented a market value ranging from a low of $[●]$17.31 to a high of $[●]$22.31 for each share of NorthwestIIBK common stock. You should obtain current market quotations for shares of First Interstate Class A common stock and NorthwestIIBK common stock. See “Market Price and Dividend Information” on page 9082 for ranges of historic market prices of First Interstate Class A common stock and NorthwestIIBK common stock.

The price of First Interstate Class A common stock might decrease after the merger.

Upon completion of the merger, holders of NorthwestIIBK common stock will become shareholders of First Interstate. First Interstate Class A common stock could decline in value after the merger. For example, during the twelve-month period ending on [●], 2018January 14, 2019 (the most recent practicable date before the printing of this document), the closing price of First Interstate Class A common stock varied from a low of $[●]$35.03 to a high of $[●]$46.95 and ended that period at $[●].$37.90. The market value of First Interstate Class A common stock fluctuates based upon general market conditions, First Interstate’s business, operations and prospects and other factors. Further, the market price of First Interstate Class A common stock after the merger may be affected by factors different from those currently affecting the common stock of First Interstate or Northwest.IIBK. The businesses of NorthwestIIBK and First Interstate Bank differ and, accordingly, the results of operations of the combined company and the market price of the combined company’sFirst Interstate’s shares of common stock following the merger may be affected by factors different from those currently affecting the independent results of operations and market prices of common stock of each of NorthwestIIBK and First Interstate. For a discussion of the business of First Interstate, First Interstate Bank and of certain factors to consider in connection with itsFirst Interstate’s business, see the documents incorporated by reference in this document and referred to under “Where You Can Find More Information”beginning on page 93.84.

NorthwestIIBK, First Interstate Bank and First Interstate will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainty about the effects of the merger on employees and customers may have an adverse effect on NorthwestIIBK, First Interstate Bank or First Interstate. These uncertainties may impair Northwest’sIIBK’s, First Interstate Bank’s or

First Interstate’s ability to attract,

retain and motivate key personnel until the merger is completed, and could cause customers and others that interact with NorthwestIIBK, First Interstate Bank or First Interstate to seek to change existing business relationships with NorthwestIIBK, First Interstate Bank or First Interstate. Retention of certain employees by NorthwestIIBK, First Interstate Bank or First Interstate may be challenging while the merger is pending, as certain employees may experience uncertainty about their future roles with the combined company. If key employees depart because of issues relating to the uncertainty and difficulty of integration, or a desire not to remain with NorthwestIIBK or First Interstate, Northwest’sIIBK’s business or First Interstate’s business could be harmed. In addition, subject to certain exceptions, NorthwestIIBK has agreed to operate its business in the ordinary course before closing, which may prevent it from pursuing certain growth opportunities. See “Description of the Merger—Conduct of Business Before the Merger”for a description of the restrictive covenants applicable to NorthwestIIBK and First Interstate.

Failure to complete the merger could negatively impact the stock prices and future businesses and financial results of First Interstate, First Interstate Bank and Northwest.IIBK.

There can be no assurance that the merger will be completed. If the merger is not completed, the ongoing businesses of First Interstate, First Interstate Bank and NorthwestIIBK may be adversely affected and First Interstate, First Interstate Bank and NorthwestIIBK will be subject to a number of risks, including the following:

 

First Interstate and NorthwestIIBK will be required to pay certain costs relating to the merger, whether or not the merger is completed, such as legal, accounting, financial advisor, proxy solicitation and printing fees;

 

under the merger agreement, First Interstate, First Interstate Bank and NorthwestIIBK are subject to certain restrictions on the conduct of their respective businesses before completing the merger, which may adversely affect their ability to execute certain of its business strategies if the merger is terminated; and

 

matters relating to the merger may require substantial commitments of time and resources by First Interstate, First Interstate Bank and NorthwestIIBK management, which could otherwise have been devoted to other opportunities that may have been beneficial to First Interstate, First Interstate Bank and NorthwestIIBK as independent companies.

In addition, if the merger is not completed, First Interstate, First Interstate Bank and/or NorthwestIIBK may experience negative reactions from the financial markets and from their respective customers and employees. First Interstate, First Interstate Bank and/or NorthwestIIBK also could be subject to litigation related to any failure to complete the merger or to proceedings commenced by First Interstate and First Interstate Bank on the one hand, or NorthwestIIBK on the other hand, against the other seeking damages or to compel the other to perform its obligations under the merger agreement. These factors and similar risks could have an adverse effect on the results of operation, business and stock prices of First Interstate, First Interstate Bank and Northwest.IIBK.

First Interstate and First Interstate Bank may be unable to successfully integrate Northwest’sIIBK’s operations or retain Northwest’sIIBK’s employees, which could adversely affect the combined company.

The merger involves the integration of two companiesbanks that have previously operated independently. The difficulties of combining the operations of the two companiesbanks include, among other things: integrating personnel with diverse business backgrounds; combining different corporate cultures; and retaining key employees.

The process of integrating operations could cause an interruption of, or loss of momentum in, the activities of the business and the loss of key personnel. The integration of the two companiesbanks will substantially benefit from the experience and expertise of certain key employees of NorthwestIIBK who are expected to be retained by First Interstate.Interstate Bank. First Interstate Bank may not be successful in retaining these employees for the time period necessary to successfully integrate Northwest’sIIBK’s operations with those of First Interstate.Interstate Bank. The diversion of management’s attention and any delays or difficulties encountered in connection with the merger and the integration of the two companies’ operations could have an adverse effect on the business and results of operations of First Interstate Bank following the merger.

Additionally, First Interstate and First Interstate Bank may not be able to successfully achieve the level of cost savings, revenue enhancements and other synergies that it expects, and may not be able to capitalize upon the existing customer

relationships of NorthwestIIBK to the extent anticipated, or it may take longer, or be more difficult or expensive than expected, to achieve these goals. These matters could have an adverse effect on First Interstate’s business, results of operation and stock price.

First Interstate and First Interstate Bank are also acquiring CMYF in the CMYF Merger and the conditions to completing that merger may result in delays in completing the IIBK merger, or make it more difficult or time consuming than expected.

First Interstate and First Interstate Bank announced the proposed acquisition of CMYF in the CMYF Merger on the same date as the IIBK merger. The CMYF Merger is subject to customary closing conditions, including receipt of regulatory approvals for the CMYF Merger, as well as the approval of the shareholders of CMYF. The preparation and filing of regulatory applications, and a separate prospectus/proxy statement, as well as planning the integration of CMYF at the same time as obtaining the regulatory approvals and planning the integration of IIBK is time consuming and could divert management attention and resources away from the IIBK merger. It is possible that because of the complexities involved in acquiring two financial institutions simultaneously, First Interstate and First Interstate Bank could experience delays in regulatory approval. This could result in the merger process taking longer than anticipated, which could be costly to First Interstate, First Interstate Bank and IIBK, disrupt First Interstate’s or IIBK’s ongoing businesses relationships with their respective clients, customers, depositors and employees or result in a failure to achieve the anticipated benefits of the IIBK merger.

The termination fee and the restrictions on solicitation contained in the merger agreement may discourage other companies from trying to acquire Northwest.IIBK.

Until the completion of the merger, with some exceptions, NorthwestIIBK is prohibited from soliciting, initiating, encouraging or participating in any discussion of or otherwise considering any inquiry or proposal that may lead to an acquisition proposal, such as a merger or other business combination transactions, with any person other than First Interstate.Interstate and First Interstate Bank. In addition, NorthwestIIBK has agreed to pay a $5.1$6.8 million termination fee to First Interstate in specified circumstances. These provisions could discourage other companies that may have an interest in acquiring NorthwestIIBK from considering or proposing such an acquisition even though those other companies might be willing to offer greater value to Northwest’sIIBK’s shareholders than First Interstate has offered in the merger. The payment of the termination fee would also have a material adverse effect on Northwest’sIIBK’s financial condition and results of operations.

Certain of Northwest’sIIBK’s directors and officers have interests that are different from, or in addition to, interests of NorthwestIIBK shareholders generally.

Certain executive officers and directors and officers of NorthwestIIBK have interests in the merger that are different from, or in addition to, the interests of NorthwestIIBK shareholders generally. These include: (1) employment and change in control agreements for certain directors andexecutive officers of Northwest and Inland Northwest BankIIBK that provide for cash severance payments upon aan involuntary termination without cause or a voluntary termination generally with good reason following the completion of the merger; (2) a cash payment in connection with the acceleration of vestingtermination of all outstanding restrictedIIBK stock awards;options; (3) settlement agreements entered into with each of Russell A. Lee, PresidentJack W. Gustavel and Chief Executive Officer of Northwest, and Holly A. Poquette, Executive Vice President and Chief Financial Officer of Northwest,Kurt R. Gustavel, concurrent with the execution of the merger agreement; (4) anon-competition agreement and a consulting and release agreement entered into with Mr. Lee concurrent with the execution of the merger agreement; (5) continued employment of Mr. LeeKurt R. Gustavel as First Interstate Bank’s Executive ViceRegional President of Special Projects; (6) continued employment of Ms. Poquetteresponsible for up to six months to facilitateoperations in the integration of Inland Northwest Bank with First Interstate Bank;Idaho and (7)Eastern Washington region; and (5) provisions in the merger agreement relating to indemnification of directors and officers and insurance for directors and officers of NorthwestIIBK for events occurring before the merger. For a more detailed discussion of these interests, see “Description of the Merger—Interests ofCertain Persons in the Merger that are Different from Yours”beginning on page 59.54.

Both First Interstate and NorthwestIIBK shareholders will have a reduced ownership and voting interest after the merger and will exercise less influence over management of the combined organization.

First Interstate shareholders and NorthwestIIBK shareholders each currently have the right to vote in the election of their respective board of directors and on various other matters affecting their respective company. Upon the completion of the merger, Northwest’sIIBK’s shareholders will become shareholders of First Interstate with a percentage ownership of the combined organization that is substantially smaller than such shareholders’ percentage ownership of Northwest. Further, becauseIIBK. Following completion of the merger, IIBK shareholders will own approximately 10.2% of the outstanding shares of First Interstate Class A common stock will be issuedand 6.7% of the aggregate outstanding shares of the First Interstate common stock, which equates to existing Northwest shareholders,2.8% of the shareholdersvoting power of First Interstate Class A common stock will have theirstock. Additionally, upon the completion of the CMYF Merger, IIBK’s shareholders percentage ownership interests diluted by approximately [●]% and voting interests diluted by approximately [●]% and the shareholders of First Interstate Class B common stock will have their ownership interests diluted by approximately [●]% and voting interests diluted by approximately [●]%.further decrease.

The reduced voting power of NorthwestIIBK shareholders is further effected by the two classes of common stock that First Interstate maintains. First Interstate Class B common stock is entitled to five votes per share, while shares of First Interstate Class A common stock, which is what will be issued to NorthwestIIBK shareholders, are

entitled to one vote per share. As of [●], 2018,January 14, 2019, members of the Scott family held [●]21,285,014 shares of First Interstate Class B common stock and, therefore, controlled in excess of [●]%71% of the voting power of First Interstate’s outstanding common stock. As a result, the Scott family will be able to exert a significant degree of influence or actual control over First Interstate’s management and affairs and over matters requiring shareholder approval, including the election of directors, a merger, consolidation or sale of all or substantially all of First Interstate’s assets and any other significant transaction. This concentrated control will limit NorthwestIIBK shareholders’ future ability to influence corporate matters, and the interests of the Scott family may not always coincide with First Interstate’s interests or your interests.

The fairness opinion to the board of directors Northwest rendered on the date of the signing of the merger agreementIIBK’s financial advisor does not reflect any changes in circumstances aftersince the date of such fairness opinions.opinion.

D.A. DavidsonOn October 11, 2018, Sandler O’Neill delivered to the board of directors of NorthwestIIBK its opinion to the effect that, as of such date and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on April 25, 2018.the review undertaken by Sandler O’Neill, as set forth in its opinion, the exchange ratio in the proposed merger was fair, from a financial point of view, to the holders of IIBK common stock. The opinion does not reflect changes that may occur or may have occurred after the date of such opinion, including changes to the operations and prospects of First Interstate or Northwest,IIBK, changes in general market and economic conditions or regulatory or other factors that may materially alter or affect the value of First Interstate Class A common stock or NorthwestIIBK common stock. The opinion speaks only as of the date on which it was rendered and not as of the date of this document or any other date. For a description of the opinion that the IIBK board of directors received from Sandler O’Neill, please refer to the section entitled “Description of the Merger—Opinion of IIBK’s Financial Advisor.”

There is no assurance when or even if the merger will be completed.

Completion of the merger is subject to satisfaction or waiver of a number of conditions. See “Description of the Merger—Conditions to Completing the Merger”beginning on page 63.58. There can be no assurance that First Interstate, First Interstate Bank and NorthwestIIBK will be able to satisfy the closing conditions or that closing conditions beyond their control will be satisfied or waived.

First Interstate and NorthwestIIBK can agree at any time to terminate the merger agreement, even if NorthwestIIBK shareholders have already voted to approve the merger agreement. First Interstate and NorthwestIIBK can also terminate the merger agreement under other specified circumstances.

Regulatory approvals may not be received, may take longer than expected, or may impose conditions that are not presently anticipated or that could have an adverse effect on the combined company following the merger.

Before the merger and the bank merger may be completed, First Interstate, First Interstate Bank and NorthwestIIBK must obtain approvals from the Federal Reserve Board, the Montana Division and the WashingtonIdaho Department. First Interstate has received the approvals from the Montana Division and the Idaho Department. Other approvals, waivers or consents from regulators may also be required. In determining whether to grant these approvals the regulators consider a variety of factors, including the regulatory standing of each party. An adverse development in either party’s regulatory standing or other factors could result in an inability to obtain approval or delay their receipt. These regulators may impose conditions on the completion of the merger or the bank merger or require changes to the terms of the merger or the bank merger. Such conditions or changes could have the effect of delaying or preventing completion of the merger or the bank merger or imposing additional costs on or limiting the revenues of the combined company following the merger and the bank merger, any of which might have an adverse effect on the combined company following the merger.

The shares of First Interstate Class A common stock to be received by NorthwestIIBK shareholders as a result of the merger will have different rights from the shares of NorthwestIIBK common stock.

Upon completion of the merger, NorthwestIIBK shareholders will become First Interstate shareholders. Their rights as shareholders of Class A common stock will be governed by Montana corporate law and the amended and restated articles of incorporation and bylaws of First Interstate. The rights associated with NorthwestIIBK common stock are governed by WashingtonIdaho law and the articles of incorporation and bylaws of NorthwestIIBK and are

different from the rights associated with First Interstate Class A common stock. See the section of this document entitled “Comparison of Rights of Shareholders” beginning on page 8175 for a discussion of the different rights associated with First Interstate Class A common stock.

Goodwill incurred in the merger may negatively affect First Interstate’s financial condition.

To the extent that the merger consideration, consisting of shares of First Interstate Class A common stock to be issued in the merger, cash paid for fractional shares, and cash paid to terminate IIBK options, exceeds the fair value of the net assets acquired in the merger, including identifiable intangibles of Northwest,IIBK, that amount will be reported as goodwill by First Interstate. In accordance with current accounting guidance, goodwill will not be amortized but will be evaluated for impairment annually. A failure to realize expected benefits of the merger could adversely impact the carrying value of the goodwill recognized in the merger, and in turn negatively affect First Interstate’s financial condition.

Risks Relating to First Interstate’s Business

You should read and consider risk factors specific to First Interstate’s business that will also affect the combined company after the merger. These risks are described in the sections entitled “Risk Factors” in First Interstate’s Annual Report on Form10-K for the fiscal year ended December 31, 2017 and in other documents incorporated by reference into this document.

UNAUDITED COMPARATIVE PRO FORMA PER SHARE DATA

The following table shows information about First Interstate’s, IIBK’s and Northwest’sCMYF’s earnings per common share, dividends per share and book value per share, and similar information giving effect to the merger (which we refer to as “pro forma” information). In presenting the unaudited comparative pro forma information as of and for the periods shown, we assumed that First Interstate, IIBK and NorthwestCMYF had been merged on the date indicated or at the beginning of the periods presented, as applicable.

The information listed as “pro forma combined” was prepared using the exchange ratio of 0.516. The information listed as “per equivalent NorthwestIIBK share” was obtained by multiplying the pro forma amounts by the exchange ratio of 0.516.0.50. First Interstate anticipates that the combined company will derive financial benefits from the merger that include reduced operating expenses and the opportunity to earn more revenue. The unaudited pro forma combined information, while helpful in illustrating the financial characteristics of First Interstate following the mergermergers under one set of assumptions, does not reflect these benefits and, accordingly, does not attempt to predict or suggest future results. The unaudited pro forma combined information also does not necessarily reflect what the historical results of First Interstate would have been had our companies been combined during this period.

The information in the following table is based on, and should be read together with, the historical financial information that we have presented in or incorporated by reference in this document.

Completion of the CMYF Merger is subject to customary closing conditions, including receipt of required regulatory approvals and approval of CMYF’s shareholders. The completion of the IIBK merger is not conditioned upon or subject to the completion of the CMYF Merger. Under the terms of the CMYF merger agreement, holders of CMYF common stock will receive 0.3784 shares of First Interstate Class A common stock for each share of CMYF common stock, which equates to an aggregate transaction value of approximately $21.0 million as of the date of the CMYF merger agreement.

At September 30, 2018, CMYF had total consolidated assets of approximately $133.1 million, total deposits of approximately $118.7 million, and total common shareholders’ equity of approximately $13.8 million.

For additional information on the CMYF Merger, including certain pro forma financial information, see “Unaudited Comparative Pro Forma Per Share Data.”

Consideration to be Received in the Merger

When the merger becomes effective, each share of NorthwestIIBK common stock issued and outstanding immediately before completion of the merger will automatically be converted into the right to receive 0.5160.50 shares of First Interstate Class A common stock, plus cash in lieu of any fractional share, without interest.

If First Interstate declares a stock dividend or distribution on shares of its common stock or subdivides, splits, reclassifies or combines the shares of First Interstate Class A common stock before the effective time of the merger, then the exchange ratio will be adjusted to provide NorthwestIIBK shareholders with the same economic effect as contemplated by the merger agreement before any of these events.

Northwest’sIIBK’s shareholders will not receive fractional shares of First Interstate Class A common stock. Instead, Northwest’sIIBK’s shareholders will receive a cash payment for any fractional shares in an amount equal to the product of (1) the fraction of a share of First Interstate Class A common stock to which he, she or it is entitled multiplied by (2) the average closing sales price of First Interstate Class A common stock over the 20 consecutive trading days ending on and including the fifth day before the closing date of the merger.

Background of the Merger

As part of the ongoing consideration and evaluation of Northwest’sIIBK’s long-term prospects and strategies, Northwest’sIIBK’s board of directors and senior management have regularly reviewedreview and assessedassess business strategies and objectives, including strategic opportunities and challenges and have considered various strategic options potentiallythat might be available to Northwest,IIBK, all with the goal of enhancing value for NorthwestIIBK shareholders. The strategic discussions have focused on among other things, remaining asa variety of factors, including: the growth opportunities and risks of IIBK continuing on a stand-alone company,basis; the risks, costs, and benefits associated with becoming a public company,merging with another financial institution; the local and national economic environment; the business and regulatory environment facing financial institutions generally, and Northwest,IIBK in particular, as well as conditionsparticular; and ongoing consolidation in the financial services industry.

As part of this ongoing evaluation, the NorthwestIIBK board of directors considered the merits of selling the institution,a sale, merging with another financial institution of similar size and complementary business, or remaining independent, as well as thestaying independent. The challenges of remaining competitive in the current economic, regulatory, and interest rate climate,environment, competition, and the potentially increased operatingimpact of new technology on the banking industry and the costs and risks associated with regulatory compliance, technology investmentsuch technological changes were also important considerations. In the months preceding the merger announcement, IIBK’s senior management had been invited to meet with the senior management of other banks, some of which were potential acquirers of IIBK. In June 2018, Jack Gustavel, IIBK’s Executive Chairman met with Kevin Riley, President and competitive forces.Chief Executive Officer of First Interstate. During that meeting, Mr. Riley indicated that First Interstate wanted to further expand in Idaho and might want to acquire IIBK. The meeting concluded, and Chairman Gustavel and Mr. Riley agreed to stay in contact.

On September 19, 2017, D.A. Davidson was invited to present various strategic alternatives with the NorthwestJune 21, 2018, at a meeting of IIBK’s board of directors, includingrepresentatives of Sandler O’Neill, the financial advisor for IIBK, presented an analysis of IIBK’s primary strategic alternatives of remaining independent versus merging with a larger financial institution. The analysis and discussion considered the impact on IIBK shareholder value along with the possible risks, benefits, and challenges of pursuing organic growth, an acquisition strategy, merger transactions, an initial public offering (which we refer to as an “IPO”), or outright strategic salethe alternatives. As part of Northwest, and to discuss the overall market conditions. Following this meeting,discussion, the NorthwestIIBK board of directors decidedreviewed the landscape of potential partners and discussed which ones might be the best fit strategically and have the strongest desire and capacity to pursuemaximize value for IIBK’s shareholders. Chairman Gustavel related various aspects of his meeting with Mr. Riley and reminded the IPO strategy.

On December 19, 2017, D.A. Davidson discussed with the Northwest board of directors of past meetings with potential acquirers of IIBK. There was considerable discussion, and at the IPO market conditions, strategy for an IPO, potential timeline and D.A. Davidson’s experience in leading public offerings for bank holding companies.

On January 19, 2018, D.A. Davidson was retained byend of the Northwestmeeting, the IIBK board of directors requested that Sandler O’Neill follow with a further assessment of the execution risk and shareholder value proposition of pursuing a merger transaction with another financial institution. The following day, representatives of Sandler O’Neill provided IIBK’s senior management with the additional analysis. After further consideration, the IIBK board of directors determined that it would be prudent to serve as lead managing underwriter for Northwestbetter understand the value that could be realized by a merger and authorized management to conductwork with Sandler O’Neill to pursue contacting a group of seven potential acquirers to determine if an IPO to raise capital for strategic growth opportunitiesattractive merger transaction might be achievable. Over the next two weeks, representatives of Sandler O’Neill and potentially to repay indebtedness. Subsequently, D.A. Davidsonsenior management prepared a package of confidential information that could be shared with interested acquirers following the signing of a nondisclosure agreement.

In early July 2018, Chairman Gustavel and Northwest began due diligenceKurt Gustavel, IIBK President and preparing necessary offering documentation.

On February 20, 2018, Northwest’s CEOChief Executive Officer, directed D.A. DavidsonSandler O’Neill to contact seven prospective acquirers to determine if there was any interest in an acquisition of Northwest, as an alternative to and in comparison with Northwest’s IPO strategy. Northwest approved a list of four companies to be contacted to solicit potential interest for an acquisition of Northwest. TwoIIBK. Six of the prospective acquirersseven expressed an interest including First Interstatein learning more about a potential acquisition and another bank (which we refer to as “Bank B”) each of which signed a confidentiality agreementexecuted nondisclosure agreements in order to receive the confidential information about Northwest.information. The confidentialitynondisclosure agreements did not restrict NorthwestIIBK from negotiating and/or entering into a definitive agreement with any other party at any time. D.A. Davidson requested for bothThe nondisclosure agreement with First Interstate was entered into on July 12, 2018. Four of the parties who entered into a nondisclosure agreement met with Chairman Gustavel and Bank BCEO Gustavel at different times over the next few weeks. One such meeting that included Chairman Gustavel and CEO Gustavel and Mr. Riley and Marcy Mutch, Executive Vice President and Chief Financial Officer of First Interstate took place on July 24, 2018. In that meeting, Mr. Riley verbally expressed First Interstate’s interest in pursuing an acquisition of IIBK in a 100% stock transaction with a fixed exchange ratio of 0.4750 First Interstate shares in exchange for each IIBK share. Based on First Interstate’s stock price at the time, the value of the transaction would have been approximately $20.50 per IIBK share.

There were other meetings throughout July and early August 2018. Following one such meeting, Party A expressed its desire to submitnon-binding indicationacquire IIBK and indicated a 100% stock deal structure with a preliminary range of interest by March 13, 2018,values, subject to due diligence, the high end of which would identify, among other items,was valued at just under $21.00 per IIBK share at the proposed purchase price, the form of consideration, the plans for the combined company, timeline to complete a transaction and conditions and approvals required to complete a strategic transaction.time.

In early MarchAugust 2018, Russell A. Lee,two of the CEO of Northwest,six potential acquirers who hadin-person meetings with signed the CEOs of bothnondisclosure agreement indicated they could not, or would not, pursue a combination at the time. Four parties: First Interstate, Party A, Party B, and Bank B, respectively.

On March 9, 2018, First Interstate sentParty C expressed a desire to submit anon-binding indication of interest describing value and other principal terms on which they would pursue the acquisition of IIBK. Each of the parties was reminded that the primary goal of the IIBK board of directors was to maximize value for IIBK’s shareholders. Sandler O’Neill

requested that thenon-binding indications of interest be communicated verbally prior to the IIBK board of directors meeting scheduled for August 16, 2018. Prior to the August 16, 2018 meeting,non-binding indications of interest were received from First Interstate, Party A, Party B and Party C.

On August 16, 2018, IIBK held its board of directors meeting to review the fournon-binding indications of interest and consider the proposed merger values as compared to the estimated value of IIBK on a stand-alone basis. Representatives of Sandler O’Neill described and compared the terms of the preliminarynon-binding indications of interest. All four of the proposals were structured asall-stock transactions with a fixed exchange ratio. First Interstate increased its exchange ratio from 0.4750 to 0.50 First Interstate shares in exchange for each IIBK share, and at the meeting, that value was equal to $22.28 per IIBK share, the highest value of the four. Party A increased the low and high end of their indication of interest, subject to due diligence, the high end of which was valued at just under $21.50 per IIBK share at the time of the meeting. The value of the Party B indication was just over $21.50 per IIBK share at the time of the meeting with the possibility of an increase or decrease based upon the outcome of third-party valuations of IIBK’s owned facilities. Party C indicated a high and low range of value, subject to due diligence, the high end of which was valued at just under $21.00 a share at the time of the meeting.

It was noted that all four parties anticipated employing CEO Gustavel in comparable management roles to assist with integration following a combination, and two of the parties contemplated one or more current representatives from the IIBK board of directors joining their board of directors. Under all four of the indications of interest, existing employment agreements and retirement plans with IIBK’s management would be honored, including applicablechange-in-control provisions. Also, eligible IIBK employees would receive severance payments and/or retention bonuses depending upon whether or not they would remain employed following consummation of a transaction. The IIBK board of directors evaluated other social considerations, including anticipated impact on IIBK employees, customers, and the communities served by IIBK, and whether or not, IIBK would continue as a subsidiary or regional division under each of the proposals. The IIBK board of directors also considered the four parties’ prior experience at integrating other acquisitions. In addition, Witherspoon Kelley, outside legal counsel to IIBK, reviewed with the board of directors their fiduciary duties to IIBK and its shareholders.

Representatives of Sandler O’Neill and IIBK’s senior management then reviewed with the IIBK board of directors the financial analyses that had been performed on the four parties, including multiple financial comparisons, past financial performance, stock valuations, performance history and trading liquidity, history of paying cash dividends, the estimates and recommendations of institutional research analysts, and the expected pro forma impact to the financial position of each party. It was noted that each party was in good financial position with ample capital, core deposit funding, good credit quality, and strong profitability. In addition, each party had a track record of successfully completing merger transactions. Representatives of Sandler O’Neill also reviewed publicly available analyst estimates of future valuations for each of the potential buyer’s stock prices. It was noted that First Interstate had an excellent performance history, even through the recent financial downturn. First Interstate was also noted to have an exceptional history of paying cash dividends, and its stock price was expected to have a good future value based on the projections of the institutional research analysts.

The IIBK board of directors then engaged in a lengthy discussion about the relative merits and risks of a transaction with each party, the cultural and reputational issues associated with a potential merger, the potential impacts on employees, customers and the communities IIBK serves, and whether IIBK could achieve the same value for shareholders by remaining independent. It was evident to the board of directors that thenon-binding indications of interest represented a significant premium to IIBK’s then current market price, tangible book value per share, earnings per share, and in most cases, could be expected to provide a better return to shareholders when compared to IIB as a standalone institution. In addition, under all of thenon-binding indications of interest, IIBK shareholders would benefit from better stock trading liquidity in varying degrees.

After further discussion related to the merits of each of the fournon-binding indications of interest and a determination that the First Interstate indication of interest was the most favorable to IIBK and its shareholders,

the IIBK board of directors unanimously authorized and instructed Chairman Gustavel and CEO Gustavel to proceed with negotiating and executing anon-bindingletter of intent with First Interstate and to Northwest whichtake such actions as they deemed necessary and appropriate to further discussions on a confidential basis. Following the meeting, IIBK requested that First Interstate provide IIBK with a written indication of interest confirming the terms that had been verbally communicated. Party A, Party B, and Party C were contacted and informed that theirnon-binding indications of interest were inadequate.

On August 17, 2018, First Interstate provided IIBK with a written indication of interest and exclusivity agreement. Also on August 17, 2018, Party A advised Sandler O’Neill of its intent to submit a revised indication of interest, and later that day, it submitted a written indication of interest that included an increased per share value for IIBK.

Northwest’sIIBK’s Reasons for the Merger and Recommendation of the Board of Directors

The NorthwestIIBK board of directors believes the merger is in the best interests of the NorthwestIIBK shareholders. After careful consideration, the NorthwestIIBK board of directors unanimously approved the merger agreement at a meeting held on April 25,October 11, 2018 and recommends that NorthwestIIBK shareholders vote “FOR” approval of the merger agreement and “FOR” the adjournment of the meeting to a later date or dates to permit further solicitation of proxies, if necessary.

In reaching its determination to unanimously approve the merger agreement, the NorthwestIIBK board of directors consulted with Northwest’sIIBK’s management, D.A. DavidsonSandler O’Neill and Witherspoon Kelley and considered a number of factors. Following is a description of each of the material factors that the NorthwestIIBK board of directors believes favor the merger:

 

the NorthwestIIBK board of directors’directors assessment, based in part on presentations by D.A. DavidsonSandler O’Neill and its management and the results of the due diligence investigation of First Interstate conducted by Northwest’sIIBK’s management and financial and legal advisors, of the business, financial performance, operations, capital level, asset quality, management, financial condition, competitive position and stock performance of First Interstate on an historical and a prospective basis, and of the combined company on a pro forma basis, including anticipated cost savings;

 

the NorthwestIIBK board of directors’ knowledge of Northwest’sIIBK’s business, operations, financial condition, earnings, asset quality and prospects;

 

the financial and growth prospects for NorthwestIIBK and its shareholders of a business combination with First Interstate as compared to continuing to operate as a stand-alone entity;

 

  

the information presented by D.A. DavidsonSandler O’Neill to the NorthwestIIBK board of directors with respect to the financial aspects of the merger and the opinion of D.A. DavidsonSandler O’Neill to the effect that, as of the date of that opinion, the exchange ratio to be paid to the NorthwestIIBK common shareholders in the transaction was fair from a financial point of view to such common shareholders (see “Description of the MergerD.A. DavidsonOpinion of IIBKs Opinion to Northwests Board of DirectorsFinancial Advisor”);

 

the dividend payment history of First Interstate and possible dividend payments following the merger;

the benefits to NorthwestIIBK and its customers of operating as part of a larger organization, including enhancements in products and services, expanded network of branch locations, higher lending limits, and greater financial resources;

 

the NorthwestIIBK board of directors’ belief that the two companies share a common vision of the importance of customer service and local decision-making and that management and employees of NorthwestIIBK and First Interstate possess complementary skills and expertise;

 

the current and prospective economic and competitive environment facing the financial services industry generally, and NorthwestIIBK in particular, including the continued rapid consolidation in the financial services industry and the competitive effects of the increased consolidation on smaller financial institutions such as Northwest;IIBK;

 

First Interstate’s interest in expanding its business bankingretail, commercial, mortgage, and commercial real estate businessesbanking operations in Northwest’sIIBK’s market areas, and the complementary market areas, banking philosophy, and the employee and community focus of both NorthwestIIBK and First Interstate;

 

First Interstate’s historical record and commitment with respect to the communities and employees of the companies it has acquired and its belief that NorthwestIIBK is a high quality financial services company with a compatible business culture and shared approach to customer service and increasing shareholder value;

 

the increasing importance of operational scale and financial resources in maintaining efficiency and remaining competitive over the long term and being able to capitalize on technological developments, which significantly impact industry competitive conditions;

the greater market capitalization and trading liquidity of First Interstate common stock in the event that Northwestif IIBK shareholders desire to sell the shares of First Interstate common stock to be received by them following completion of the merger;

 

the expected social and economic impact of the merger on the constituencies served by Northwest,IIBK, including its borrowers, customers, depositors, employees, suppliers, and communities;

 

the employee and severance benefits to be provided to NorthwestIIBK employees and career opportunities in a larger organization;

 

that Northwest’sIIBK’s shareholders will be able to exchange their shares in atax-free transaction; and

 

the NorthwestIIBK board of directors’ assessment with the assistance of counsel concerning the expected likelihood that First Interstate would obtain all regulatory approvals required for the merger.

In the course of its deliberations regarding the merger, the NorthwestIIBK board of directors also considered the following information that the NorthwestIIBK board of directors determined did not outweigh the benefits to NorthwestIIBK and its shareholders expected to be generated by the merger:

 

the potential risk of diverting management attention and resources from the operation of Northwest’sIIBK’s business and towards the completion of the merger;

 

the restrictions on the conduct of Northwest’sIIBK’s business prior to the completion of the merger, which are customary for public company merger agreements involving financial institutions, but which, subject to specific exceptions, could delay or prevent NorthwestIIBK from undertaking business opportunities that may arise or any other action it would otherwise take with respect to the operations of NorthwestIIBK absent the pending merger;

 

the potential risks associated with achieving anticipated cost synergies and savings and successfully integrating Northwest’sIIBK’s business, operations and workforce with those of First Interstate;

 

the transaction costs;

 

  

that the interests of certain of Northwest’sIIBK’s directors and executive officers may be different from, or in addition to, the interests of Northwest’sIIBK’s other shareholders as described under the heading “—Interests of Certain Persons in the Merger that are Different from YoursYours;;

that, while NorthwestIIBK expects that the merger will be consummated, there can be no assurance that all conditions to the parties’ obligations to complete the merger agreement will be satisfied, including the risk that necessary regulatory or shareholder approvals might not be obtained and, as a result, the merger may not be consummated;

 

the risk of potential employee attrition and/or adverse effects on Northwest’sIIBK’s business and customer relationships as a result of the pending merger;

 

that: (1) NorthwestIIBK would be prohibited from affirmatively soliciting acquisition proposals after execution of the merger agreement; and (2) NorthwestIIBK would be obligated to pay to NorthwestFirst Interstate a termination fee of $5.1$6.8 million if the merger agreement is terminated under certain circumstances, all of which may discourage other parties potentially interested in a strategic transaction with NorthwestIIBK from pursuing such a transaction; and

 

  

the other risks described under“Risk Factors” beginning on page 14.15.

The above discussion of the information and factors considered by the NorthwestIIBK board of directors is not intended to be exhaustive, but includes the material factors the board of directors considered. In reaching its determination to approve and recommend the acquisition, the board of directors did not assign any relative or specific weights to the foregoing factors, and individual directors may have given differing weights to different factors. The NorthwestIIBK board of directors also did not undertake to make any specific determination as to whether any factor was decisive in reaching its ultimate determination. The NorthwestIIBK board of directors instead based its recommendation on the totality of the information presented.

In considering the recommendation of the NorthwestIIBK board of directors with respect to the proposal to adopt and approve the merger agreement, NorthwestIIBK shareholders should be aware that Northwest’sIIBK’s directors and executive officers have interests in the merger that may be different from, or in addition to, those of other NorthwestIIBK shareholders. The board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the merger and in recommending that the merger agreement be approved by Northwest’sIIBK’s shareholders. See “—Interests of Certain Persons in the Merger that are Different from Yours.”

In the course of its deliberations with respect to the merger, the NorthwestIIBK board of directors discussed the anticipated impact of the merger on Northwest,IIBK, its shareholders, and its various other constituencies, and determined that the benefits to NorthwestIIBK and its constituencies expected to result from the merger would likely outweigh any disadvantages identified during the board of directors’ deliberations.

For the reasons set forth above, the NorthwestIIBK board of directors determined that the merger, the merger agreement, and the transactions contemplated by the merger agreement are advisable and in the best interests of Northwest’sIIBK’s shareholders, and approved the merger agreement. The NorthwestIIBK board of directors unanimously recommends that the NorthwestIIBK shareholders vote “FOR” the approval of the merger agreement and “FOR” the NorthwestIIBK adjournment proposal.

This summary of the reasoning of the NorthwestIIBK board of directors and other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under “Cautionary Statement About Forward-Looking Statements.”

Set forth below is a summary of the material financial analyses performed by D.A. Davidson in connection withIn rendering its opinion.opinion, Sandler O’Neill performed a variety of financial analyses. The summary of the analyses of D.A. Davidson set forth below is not a complete description of the analysisanalyses underlying itsSandler O’Neill’s opinion or the presentation made by Sandler O’Neill to IIBK’s board of directors, but is a summary of all material analyses performed and the order in which these analyses are described below is not indicative of any relative weight or importance given to those analysespresented by D.A. Davidson.Sandler O’Neill. The following summaries of financial analyses includesummary includes information presented in tabular format.

The tables alone aredo not constitute a complete description of the financial analyses.

Unless otherwise indicated, the following quantitative information, The preparation of a fairness opinion is a complex process involving subjective judgments as to the extentmost appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Sandler O’Neill believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Sandler O’Neill’s comparative analyses described below is identical to IIBK or First Interstate and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or transaction values, as the case may be, of IIBK and the companies to which they are being compared. In arriving at its opinion, Sandler O’Neill did not attribute any particular weight to any analysis or factor that it is basedconsidered. Rather, Sandler O’Neill made qualitative judgments as to the significance and relevance of each analysis and factor. Sandler O’Neill did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion, rather, Sandler O’Neill made its determination as to the fairness of the exchange ratio on market data, is based on market datathe basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

In performing its analyses, Sandler O’Neill also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of April 23, 2018which are beyond the control of IIBK, First Interstate and isSandler O’Neill. The analyses performed by Sandler O’Neill are not necessarily indicative of market conditions afteractual values or future results, both of which may be significantly more or less favorable than suggested by such date.

Implied Valuation Multiplesanalyses. Sandler O’Neill prepared its analyses solely for Northwest basedpurposes of rendering its opinion and provided such analyses to IIBK’s board of directors at its October 11, 2018 meeting. Estimates on the Merger Considerationvalues of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Sandler O’Neill’s analyses do not necessarily reflect the value of IIBK common stock or the prices at which IIBK common stock or First Interstate common stock may be sold at any time. The analyses of Sandler O’Neill and its opinion were among a number of factors taken into consideration by IIBK’s board of directors in making its determination to approve the merger agreement and should not be viewed as determinative of the exchange ratio or the decision of IIBK’s board of directors or management with respect to the fairness of the merger. The type and amount of consideration payable in the merger were determined through negotiation between IIBK and First Interstate.

IIBK Net Present Value Analysis for NorthwestAnalyses.

D.A. Davidson Sandler O’Neill performed an analysis that estimated the net present value per share of NorthwestIIBK common stock under various circumstances. The analysis assumed: (1) Northwestassuming IIBK performed in accordance with management’s budgetinternal financial

projections for the years ending December 31, 2018 andthrough December 31, 2019;2022, as provided by the senior management of IIBK and (2) an estimated long-term growth ratedividend payout ratio for the years thereafter,ending December 31, 2018 through December 31, 2022, as discussed with and confirmeddirected by Northwest management.the senior management of IIBK. To approximate the terminal value of Northwesta share of IIBK common stock at December 31, 2023, D.A. Davidson2022, Sandler O’Neill applied price to 2022 earnings per share multiples ofranging from 12.0x to 22.0x and multiples ofprice to December 31, 2022 tangible book value per share multiples ranging from 140.0%140% to 240.0%240%. The income streams and terminal values were then discounted to present values using different discount rates ranging from 12.00%9.0% to 17.00%15.0% which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Northwest’sIIBK common stock. In evaluatingAs illustrated in the discount rate, D.A. Davidson used industry standard methodsfollowing tables, the analysis indicated an imputed range of addingvalues per share of IIBK common stock of $13.52 to $28.93 when applying multiples of earnings per share and $11.73 to $23.28 when applying multiples of tangible book value per share.

Sandler O’Neill also considered and discussed with the current risk-free rate, which is based on the20-year Treasury yield, plus the published Duff & Phelps Industry Equity Risk Premium and the published Duff & Phelps Size Premium.

At the April 25, 2018 NorthwestIIBK board of directors meeting, D.A. Davidsonhow this analysis would be affected by changes in the underlying assumptions, including variations with respect to projected net income. To illustrate this impact, Sandler O’Neill performed a similar analysis assuming IIBK’s net income varied from 15% above projections to 15% below projections. This analysis resulted in the following range of per share values for IIBK common stock, applying the price to 2022 earnings per share multiples range of 12.0x to 22.0x referred to above and a discount rate of 12.68%.

First Interstate Net Present Value Analyses. Sandler O’Neill performed an analysis that estimated the net present value per share of First Interstate common stock assuming that First Interstate performed in accordance with publicly available mean analyst net income estimates for First Interstate for the years ending December 31, 2018 through December 31, 2020, as well as an estimated long-term net income growth rate for the years thereafter and estimated annual dividends per share for the years ending December 31, 2018 through December 31, 2022, as directed by the senior management of First Interstate. To approximate the terminal value of a share of First Interstate common stock at December 31, 2022, Sandler O’Neill applied price to 2022 earnings per share multiples ranging from 12.0x to 20.0x and price to December 31, 2022 tangible book value per share multiples ranging from 180% to 280%. The terminal values were then discounted to present values using different discount rates ranging from 8.0% to 13.0% which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of First Interstate common stock. As illustrated in the following tables, the analysis indicatesindicated an imputed range of values per share of NorthwestFirst Interstate common stock of $9.66$31.67 to $22.77$59.92 when applying the pricemultiples of earnings per share and $34.00 to earnings multiples to the financial forecasts and $10.62 to $23.41$60.63 when applying the multiples of tangible book value to the financial forecasts.

Illustrative Net Present Value Analysis for Pro Forma Northwest

For illustrative purposes, D.A. Davidson performed an analysis that estimated the net present value per share of Northwest common stock if reinvested in First Interstate under various circumstances, including the impact of the merger with First Interstate. The analysis assumed (1) Northwest performed in accordance with management budget for the years ending December 31, 2018 and December 31, 2019, (2) an estimated long-term growth rate for the years thereafter, as discussed with and confirmed by Northwest management; and (3) the pro forma financial impact of the merger with First Interstate including the cost savings estimates, purchase accounting adjustments and transaction expenses, as discussed with and confirmed by Northwest management. The analysis also assumed (1) First Interstate performed in accordance with publicly available consensus Street estimates for the years ending December 31, 2018 and December 31, 2019, and (2) an estimated long-term growth rate for the years thereafter, as discussed with and confirmed by First Interstate and Northwest management. To approximate the terminal value of Northwest common stock at December 31, 2022, D.A. Davidson applied forward price to earnings multiples of 12.0x to 22.0x and multiples of tangible book value ranging from 180.0% to 280.0%. The income streams and terminal values were then discounted to present values using different discount rates ranging from 8.00% to 13.00% chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Northwest’s common stock. In evaluating the discount rate, D.A. Davidson used industry standard methods of adding the current risk-free rate, which is based on the20-year Treasury yield, plus the published Duff & Phelps Industry Equity Risk Premium and the published Duff & Phelps Size Premium.

At the April 25, 2018 Northwest board of directors meeting, D.A. DavidsonSandler O’Neill 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

Pro Forma Merger Analysis. Sandler O’Neill analyzed certain potential pro forma effects of the merger. In performing this analysis, Sandler O’Neill utilized the following information and assumptions: (1) the merger closes on March 31, 2019; (2) certain internal financial projections for IIBK for the years ending December 31, 2018 through December 31, 2022, as provided by the senior management of IIBK, as well as an estimated dividend payout ratio for the years ending December 31, 2018 through December 31, 2022, as directed by the senior management of IIBK; (3) publicly available mean analyst net income estimates for First Interstate for the years ending December 31, 2018 through December 31, 2020, as well as a long-term net income growth rate for the years thereafter and annual dividends per share for the years ending December 31, 2018 through December 31, 2022, as directed by the senior management of First Interstate; and (4) certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as estimated revenue impacts following the closing of the merger, as directed by the senior management of First Interstate. The analysis indicated that the merger could be accretive to First Interstate’s earnings per share (excludingone-time transaction costs and expenses) in the following tables, the analysis indicates an imputed range of values per share of Northwest common stock, after adjusting for the exchange ratio of 0.516, of $16.62years ending December 31, 2019 through December 31, 2022, and dilutive to $35.70 when applying the forward price to earnings multiples to the financial forecasts and $17.50 to $32.31 when applying the multiples ofFirst Interstate’s estimated tangible book value to the financial forecasts.at closing.

Financial Impact Analysis

D.A. Davidson performed pro forma merger analyses that combined projected income statement and balance sheet information of Northwest and First Interstate. 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 First Interstate. In the course of this analysis, D.A. Davidson used the publicly available consensus street estimates for First Interstate for the years ending December 31, 2018 and December 31, 2019, and used management’s budget for Northwest for the years ending December 31, 2018 and December 31, 2019 provided by Northwest management. This analysis indicated that the merger is expected to be accretive to First Interstate’s estimated earnings per share beginning in 2018, after excludingnon-recurring transaction-related expenses. The analysis also indicated that the merger is expected to be dilutive to tangible book value per share for First Interstate and that First Interstate would maintain capital ratios in excess of those required for First Interstate to be considered well-capitalized under existing regulations. For allclosing of the above analyses,transaction, and noted that the actual results achieved by First Interstate and Northwest prior to and following the merger willcombined company may vary from the projected results and the variations may be material.

D.A. Davidson preparedSandler O’Neill’s Relationship. Sandler O’Neill acted as IIBK’s financial advisor in connection with the transaction and will receive a fee for its analyses for purposes of providing its opinionservices in an amount equal to Northwest’s board of directors as to the fairness, from a financial point of view,1.40% of the exchange ratio toaggregate purchase price, which fee at the holderstime of Northwest’s common stock inannouncement based on the proposed merger and to assist Northwest’s board of directors 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 Northwest, First Interstate or D.A. Davidson or any other person assumes responsibility if future results are materially different from those forecasted.

D.A. Davidson’s opinionclosing price on October 10, 2018 was oneapproximately $2.6 million. Sandler O’Neill received $150,000 of many factors considered bysuch fee upon the Northwest’s board of directors in its evaluationsigning of the merger agreement and should not be viewed as determinativethe remainder is contingent upon consummation of the viewsmerger. Sandler O’Neill also received a fee of $350,000 for rendering its opinion, which fairness opinion fee will be credited in full towards the portion of the boardfee becoming due and payable to Sandler O’Neill on the day of directorsclosing of Northwest or management with respectthe merger. IIBK has also agreed to indemnify Sandler O’Neill against certain claims and liabilities arising out of Sandler O’Neill’s engagement. In the merger ortwo years preceding the merger consideration.

Certain Financial Projections Utilized by the NorthwestIIBK Board of Directors and Northwest’sIIBK’s Financial Advisor

NorthwestIIBK does not, as a matter of course, publicly disclose forecasts or internal projections as to future performance, earnings, or other results due to, among other reasons, the uncertainty of the underlying assumptions and estimates. However, Northwest’sIIBK’s management provided its financial advisor, D.A. Davidson,Sandler O’Neill, and First Interstate with certainnon-public unaudited prospective financial information regarding NorthwestIIBK prepared by Northwest’sIIBK’s management that was considered by D.A. Davidson for the purpose ofSandler O’Neill in preparing its fairness opinion, as described in this document under the heading “– D.A. Davidson’s Opinion to Northwest’s Board of DirectorsIIBK’s Financial Advisor” beginning on page 35. Thisnon-public unaudited prospective financial information was prepared as part of Northwest’sIIBK’s overall process of analyzing various strategic initiatives, and was not prepared for the purposes of, or with a view toward, public disclosure or with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information, published guidelines of the SEC regarding forward-looking statements, or GAAP.generally accepted accounting principles. A summary of certain significant elements of this information is set forth below. The information included below does not comprise all of the prospective financial information provided by NorthwestIIBK to D.A. DavidsonSandler O’Neill and First Interstate.

Although presented with numeric specificity, the financial forecasts reflect numerous estimates and assumptions of Northwest’sIIBK’s management made at the time they were prepared, and assume execution of various strategic initiatives that NorthwestIIBK is no longer pursuing in light of the merger. These and the other estimates and assumptions underlying the financial forecasts involve judgments with respect to, among other things, the future interest rate environment and other economic, competitive, regulatory, and financial market conditions and future business decisions that may not be realized and that are inherently subject to significant business, economic, competitive, and regulatory uncertainties and contingencies, including, among other things, the inherent uncertainty of the business and economic conditions affecting the industry in which NorthwestIIBK operates, and the risks and uncertainties described under “Risk Factors” beginning on page 1415 and “Cautionary Note AboutForward-Looking Statements” beginning on page 19, all of which are difficult to predict and many of which are outside the control of NorthwestIIBK and will be beyond the control of the combined company. There can be no assurance that the underlying assumptions would prove to be accurate or that the projected results would be realized, and actual results likely would differ materially from those reflected in the financial forecasts, whether

or not the merger is completed. Further, these assumptions do not include all potential actions that management could or might have taken during these time periods.

The inclusion in this document of thenon-public unaudited prospective financial information below should not be regarded as an indication that Northwest,IIBK, First Interstate, their respective boards of directors, or D.A. DavidsonSandler O’Neill considered, or now consider, these projections and forecasts to be a reliable predictor of future results. The financial forecasts are not fact and should not be relied upon as being necessarily indicative of future results, and this information should not be relied on as such. In addition, this information represents NorthwestIIBK management’s evaluation at the time it was prepared of certain measures of Northwest’sIIBK’s expected future financial performance on a stand-alone basis, assuming execution of certain strategic initiatives. The unaudited prospective financial information does not give effect to the merger, including the impact of negotiating or executing the merger agreement, the expenses that may be incurred in connection with consummating the merger, the potential synergies that may be achieved by the combined company as a result of the merger, the effect on either First Interstate or Northwest,IIBK, as applicable, of any business or strategic decision or action that has been or will be taken as a result of the merger agreement having been executed, or the effect of any business or strategic decisions or actions that would likely have been taken if the merger agreement had not been executed, but that were instead altered, accelerated, postponed, or not taken in anticipation of the merger.

No assurances can be given that these financial forecasts and the underlying assumptions are reasonable or that, if they had been prepared as of the date of this document, similar assumptions would be used. In addition, the financial forecasts may not reflect the manner in which First Interstate would operate the NorthwestIIBK business after the merger. First Interstate and NorthwestIIBK do not intend to, and each disclaims any obligation to, make publicly available any update or other revision to this unaudited prospective financial information to reflect circumstances occurring since its preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error, or to reflect changes in general economic or industry conditions.

The financial forecasts summarized in this section were prepared by and are the responsibility of the management of Northwest.IIBK. No independent registered public accounting firm has examined, compiled, or otherwise performed any procedures with respect to the prospective financial information contained in these financial forecasts and, accordingly, no independent registered public accounting firm has expressed any opinion or given any other form of assurance with respect thereto and no independent registered public accounting firm assumes any responsibility for the prospective financial information.

Further, the unaudited prospective financial information does not take into account the effect on Northwest or Inland Northwest BankIIBK of any possible failure of the merger to occur. None of Northwest, Inland Northwest Bank, or D.A. Davidson,Neither IIBK nor Sandler O’Neill, or their respective affiliates, officers, directors, advisors, or other representatives has made, makes, or is authorized in the future to make any representation to any shareholder of Northwest,IIBK, or other person regarding Northwest’sIIBK’s ultimate performance compared to the information contained in the unaudited prospective financial information or that the projected results will be

achieved. The inclusion of the unaudited prospective financial information herein should not be deemed an admission or representation by First Interstate or NorthwestIIBK that it is viewed as material information of Northwest or Inland Northwest BankIIBK particularly in light of the inherent risks and uncertainties associated with such projections.

In light of the foregoing, and taking into account that the NorthwestIIBK special meeting will be held several months after the unaudited prospective financial information was prepared, as well as the uncertainties inherent in any forecasted information, NorthwestIIBK shareholders are cautioned not to place unwarranted reliance on such information.

The following table presents select unaudited prospective financial data of NorthwestIIBK for the years ending December 31, 2018 through 20192022 prepared by Northwest’sIIBK’s management and provided to D.A. DavidsonSandler O’Neill and First Interstate.

IIBK’s community banking orientation, its favorable reputation within its local communities and its compatibility with First Interstate and its subsidiaries;

 

First Interstate management’s review of the business, operations, earnings and financial condition, including asset quality, of Northwest;IIBK;

 

that following the mergers with IIBK and CMYF, First Interstate will have the sixth largest market share in Idaho;

First Interstate’s expectation that it will achieve cost savings equal to 56% of IIBK’s current annualizednon-interest expense;

that the transaction is expected to be accretive to earnings per share in 2019;

the pro forma financial effects of the proposed transaction, including the expected dilution to tangible book value per share;

continued geographic diversificiation into attractive, high growth markets in the Pacific Northwest, including Boise and Coeur d’Alene;

obtaining low cost deposits and significant execess liquidity;

the scale, scope and strength of operations, product lines and delivery systems that could be achieved by combining First Interstate and Northwest;IIBK;

 

the complementary nature of the business, market areas and corporate cultures of First Interstate and Northwest;IIBK;

 

First Interstate’s historic performance in similar markets, including its recent successes in Oregon, Idaho and Washington following its acquisitionacquisitions of Bank of the Cascades in 2017;2017 and Inland Northwest Bank in 2018;

 

the expectation that the merger will create the opportunity for the combined company to have superior future earnings and prospects compared to First Interstate’s earnings and prospects on a stand-alone basis;

First Interstate’s successful track record of creating shareholder value through merger and acquisition transactions, including its proven experience in successfully integrating acquired businesses and management’s belief that it will be able to integrate NorthwestIIBK with First Interstate Bank successfully;

 

the financial presentation, dated April 23,October 10, 2018, of SandlerPiper Jaffray & Co. (“Piper”) to the First Interstate board of directors and the opinion, dated April 23,October 10, 2018, of SandlerPiper to the First Interstate board of directors as to the fairness, from a financial point of view and as of the date of the opinion, to First Interstate of the exchange ratiomerger consideration in the proposed merger;

 

the review by First Interstate’s board of directors with its management and legal advisors of the structure and other terms of the merger and the expectation of First Interstate’s legal advisors that the merger will qualify as a transaction of a type that is generallytax-free to NorthwestIIBK shareholders for U.S. federal income tax purposes (except with respect to cash received in lieu of fractional shares of First Interstate Class A common stock); and

 

First Interstate’s expectation that it will achieve cost savings equal to 30% of Northwest’s current annualizednon-interest expense;

that the transaction is expected to be accretive to earnings per share;

the pro forma financial effects of the proposed transaction, including the expected dilution to tangible book value per share; and

the likelihood of regulators approving the merger without burdensome conditions or delay.

The foregoing discussion of the information and factors considered by First Interstate’s board of directors is not intended to be exhaustive. In reaching its decision to approve the merger agreement, the merger and the other transactions contemplated by the merger agreement, First Interstate’s board of directors did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. First Interstate’s board of directors considered all these factors as a whole, with the assistance of First Interstate’s management and First Interstate’s outside financial and legal advisors, and overall considered the factors to be favorable to, and to support, its determination.

Treatment of NorthwestIIBK Stock Purchase Warrants and Restricted StockOptions

At the effective time of the merger, each stock purchase warrantoption to purchase shares of NorthwestIIBK common stock outstanding immediately before the effective time of the merger, whether or not vested, will be canceledcancelled and, upon First Interstate’s receipt of a warrant terminationan option surrender agreement from the holder, exchanged for a cash payment equal to the product of (1) the number of shares of NorthwestIIBK common stock subject to the stock purchase warrantoption multiplied by (2) the amount by which the product of the average closing price and the exchange ratiomerger consideration exceeds the exercise price of such warrant,option, less applicable withholding taxes.

At For purposes of this calculation, the effective timemerger consideration is the product of the merger, each outstanding share of restricted stock will vest and be converted intoexchange ratio times the right to receive 0.516 sharesaverage closing sales price of First Interstate Class A common stock.stock over the 20 consecutive trading days ending on the fifth day before the closing date of the merger.

Surrender of Stock Certificates

The conversion of NorthwestIIBK common stock into the right to receive the merger consideration will occur automatically at the effective time of the merger. As soon as practicable after the completion of the merger, the exchange agent will mail to NorthwestIIBK shareholders a letter of transmittal, together with instructions for the exchange of their NorthwestIIBK common stock certificates for the merger consideration. Until you surrender your NorthwestIIBK stock certificates for exchange after completion of the merger, you will not be paid dividends or other distributions declared after the merger with respect to any First Interstate Class A common stock into which your NorthwestIIBK shares have been converted. When you surrender your NorthwestIIBK stock certificates accompanied by a properly completed letter of transmittal, First Interstate will pay any unpaid dividends or other distributions, without interest, that had become payable with respect to the shares of First Interstate Class A common stock into which your NorthwestIIBK shares had been converted.

If you own shares of NorthwestIIBK common stock in “street name” through a broker, bank or other nominee, you should receive or seek instructions from the broker, bank or other nominee holding your shares concerning how to surrender your shares of NorthwestIIBK common stock in exchange for the merger consideration.

If you own shares of NorthwestIIBK common stock in book-entry form, you are not required to take any additional action to exchange such shares for the merger consideration. Promptly following the completion of the merger,

shares of NorthwestIIBK common stock held in book-entry form automatically will be exchanged for shares of First Interstate Class A common stock in book-entry form and cash to be paid in exchange for fractional shares, if any.

If your NorthwestIIBK stock certificates have been lost, stolen or destroyed, you will have to provide an affidavit claiming your NorthwestIIBK stock certificates to be lost, stolen or destroyed, and post a bond in such amount as the exchange agent may direct before you receive any consideration for your shares.

After the completion of the merger, there will be no further transfers of NorthwestIIBK common stock. NorthwestIIBK stock certificates presented for transfer after the completion of the merger will be canceledcancelled and exchanged for the merger consideration.

Accounting Treatment of the Merger

First Interstate will account for the merger under the “acquisition” method of accounting according to U.S. generally accepted accounting principles. Using the acquisition method of accounting, the assets (including identifiable intangible assets) and liabilities of NorthwestIIBK will be recorded by First Interstate at their respective fair values at the time of the completion of the merger. The excess of First Interstate’s purchase price over the net fair value of the assets acquired and liabilities assumed will then be recorded as goodwill.

Material U.S. Federal Income Tax Consequences of the Merger

General. The following discussion sets forth the material United StatesU.S. federal income tax consequences of the merger to U.S. holders (as defined below) of NorthwestIIBK common stock. This discussion does not address any tax consequences arising under the laws of any state, locality, foreign jurisdiction or U.S. federal tax laws other than federal income tax law. This discussion is based upon the Internal Revenue Code, the regulations of the United States Department of the Treasury and court and administrative rulings and decisions in effect on the date of this document. These laws may change, possibly retroactively, and any change could affect the continuing validity of this discussion.

For purposes of this discussion, the term “U.S. holder” means:

 

an individual who is a citizen or resident of the United States for U.S. federal income tax purposes;

 

a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof or anythe District of its political subdivisions;Columbia;

S. Treasury regulations to be treated as United StatesU.S. person; or

 

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

This discussion assumes that you are a U.S. holder and you hold your shares of NorthwestIIBK common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code. Further, the discussion does not address all aspects of United StatesU.S. federal income taxation that may be relevant to you in light of your particular circumstances or that may be applicable to you if you are subject to special treatment under the United StatesU.S. federal income tax laws, including if you are:

 

a financial institution;

 

atax-exempt organization;

 

an S corporation

a pass-through entity or other pass-through entity;investor therein;

 

an insurance company;

a mutual fund;

 

a mutual fund;

If a partnership (including an entity treated as a partnership for United StatesU.S. federal income tax purposes) holds NorthwestIIBK common stock, the tax treatment of a partner in the partnership will generally depend on the status of such partner and the activities of the partnership.

This discussion is not intended to be tax advice to any particular holder of NorthwestIIBK common stock. Tax matters regarding the merger are complicated, and the tax consequences of the merger to you will depend on your particular situation. NorthwestIIBK shareholders are urged to consult their tax advisors as to the U.S. federal income tax consequences of the merger, as well as the effects of state, local, federalnon-income andnon-U.S. tax laws.

It is a condition to the closing of the merger that First Interstate receive the opinion of its legal counsel, Luse Gorman, PC, and NorthwestIIBK receive the opinion of its legal counsel, Witherspoon Kelley, each dated as of the effective time of the merger, substantially to the effect that, on the basis of facts, representations and assumptions set forth or referred to in thateach opinion (including factual representations contained in certificates of officers of First Interstate and Northwest)IIBK), the merger will be treated for U.S. federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code. The tax opinions are not binding on the Internal Revenue Service, which we refer to as the “IRS,” or any court. First Interstate and NorthwestIIBK have not sought and will not seek any ruling from the IRS regarding any matters relating to the merger and, as a result, there can be no assurance that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. In addition, if any of the representations or assumptions upon which the opinions are based are inconsistent with the actual facts, the U.S. federal income tax consequences of the merger could be adversely affected.

Based onAssuming that the merger is completed in the manner set forth in the merger agreement, and that the representations found in the merger agreement and in the officers’ certificates provided by First Interstate and IIBK delivered at the time of closing will be true and complete without qualification as of the effective time of the merger, it is the opinion of each of Luse Gorman, PC and Witherspoon Kelley that the merger will qualify as a reorganization“reorganization” within the meaning of Section 368(a) of the Internal Revenue Code,Code.

Based solely on the information set forth herein, and subject to the assumptions, qualifications and limitations set forth herein and in their respective federal income tax opinions filed as exhibits to the registration

statement on FormS-4, this discussion of the material U.S. federal income tax consequences of the merger, to the extent such discussion expresses conclusions as to the application of U.S. federal income tax law, constitutes the opinions of Luse Gorman, PC, legal counsel to First Interstate, and Witherspoon Kelley, legal counsel to IIBK. In rendering their respective tax opinions, each counsel relied upon representations and covenants, including those contained in officers’ certificates of First Interstate and IIBK, reasonably satisfactory in form and substance to each such counsel. If any of the representations, covenants or assumptions upon which the opinions are based are inconsistent with the actual facts, the U.S. federal income tax consequences of the merger could be adversely affected. Copies of the tax opinions are attached as Exhibits 8.1 and 8.2 to the registration statement onForm S-4.

Subject to the foregoing, the material U.S. federal income tax consequences of the merger are as follows:

 

No gain or loss will be recognized by a U.S. holder of NorthwestIIBK common stock upon the receipt of shares of First Interstate Class A common stock in exchange thereforfor such holder’s IIBK common stock pursuant to the merger (except in respect of cash received in lieu of fractional shares, as discussed below);

 

The aggregate adjusted tax basis of the shares of First Interstate Class A common stock received by the U.S. holder in the merger will be the same as the aggregate adjusted tax basis of shares of NorthwestIIBK common stock surrendered in exchange therefor, reduced by the tax basis allocable to any fractional share of First Interstate Class A common stock for which cash is received;

 

The holding period of First Interstate Class A common stock received by a U.S. holder will include the holding period of the NorthwestIIBK common stock exchanged therefor; and

 

Although no fractional shares of First Interstate Class A common stock will be issued in the merger, a U.S. holder who receives cash in lieu of such a fractional share of First Interstate Class A common stock will generally be treated as having received the fractional share pursuant to the merger and then having sold that fractional share of First Interstate Class A common stock for cash. As a result, a U.S. holder will generally recognize gain or loss equal to the difference between the amount of cash received and the portion of the holder’s aggregate adjusted tax basis of the shares of NorthwestIIBK common stock surrendered that is allocable to its fractional share. Any capital gain or loss will be long-term capital gain or loss if the holding period for the fractional share (including the holding period of the shares of NorthwestIIBK common stock surrendered therefor) is more than one year. Long-term capital gains of individuals generally are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

For purposes of the above discussion of the basis and holding periods for shares of NorthwestIIBK stock and First Interstate Class A common stock, NorthwestIIBK shareholders who acquired different blocks of NorthwestIIBK common stock

at different times or at different prices must calculate their basis and holding periods separately for each identifiable block of such stock exchanged or received in the merger.

Backup Withholding. Payments of cash (including cash in lieu of a fractional share, if any) to aAnon-corporate U.S. holder of Northwest stock may under certain circumstances, be subject to information reporting and backup withholding (currently at a rate of 24%) unless such holder provides proof of an applicable exemption or,on any cash received in the casemerger, including cash received in lieu of backupa fractional share of First Interstate Class A common stock. Backup withholding furnishes itsgenerally will not apply, however, to U.S. holders who:

Furnish a correct taxpayer identification number, certify that they are not subject to backup withholding on FormW-9 or successor form and otherwise compliescomply with all the applicable requirements of the backup withholding rules. rules; or

Provide proof that they are otherwise exempt from backup withholding.

Any amounts withheld from payments to a U.S. holder of Northwest stock under the backup withholding rules are not an additional tax andwill generally will be allowed as a refund or credit against suchthe U.S. holder’s U.S. federal income tax liability, provided that the holder timely furnishes the required information is timely furnished to the IRS.

Reporting Requirements. U.S. holders of NorthwestIIBK common stock who receive First Interstate Class A common stock pursuant to the merger will be required to retain records pertaining to the merger, and any such holder who, immediately before the merger, holds at least 5%1% (by vote or value) of the outstanding NorthwestIIBK stock, or securities of NorthwestIIBK with a basis for U.S. federal income tax purposes of at least $1 million, will be required to file with its U.S. federal income tax return for the year in which the merger takes place a statement setting forth certain facts relating to the merger. U.S. holders are urged to consult with their tax advisors with respect to these and other reporting requirements applicable to the merger.

The preceding discussion is a summary of the material U.S. federal income tax consequences of the merger to a U.S. holder of NorthwestIIBK stock and does not address all potential tax consequences that apply or that may vary with, or are contingent on, individual circumstances, and should not be construed as tax advice. Moreover, the discussion does not address any U.S. federalnon-income tax or any foreign, state or local tax consequences of the merger. Tax matters are very complicated and, accordingly, we strongly urge you to consult with a tax advisor to determine the particular federal, state, local and foreign income and other tax consequences to you of the merger.

Regulatory Matters Relating to the Merger

Completion of the merger is subject to the receipt of all required approvals and consents from regulatory authorities. The merger is subject to approval by the Federal Reserve Board, the Montana Division and the WashingtonIdaho Department. First Interstate has filed the required applications. While First Interstate does not know of any reason why it would not obtain the approvals in a timely manner, other than the complexities involved in acquiring two financial institutions simultaneously, First Interstate cannot be certain when or if it will receive the regulatory approvals.

Federal Reserve Board.The merger and the bank merger areis subject to approval by the Federal Reserve Board under the Bank Holding Company Act of 1956, as amended, and the Bank Merger Act, respectively.Act.

The Federal Reserve Board takes into consideration a number of factors when acting on applications under the Bank Merger Act and the Bank Holding Company Act, including: (1) the financial and managerial resources and the effect of the proposed merger on these resources (including capital and pro forma capital ratios of the combined organization, the management expertise, internal controls, and risk management systems, especially those with respect to compliance with laws applicable to consumers and “fair lending” laws); (2) the effect of the proposal on competition; (3) the future prospects of the existing and merged entities; (4) the convenience and needs of the communities served; (5) any risk to the stability of the United States banking or financial system; and (6) the effectiveness of the acquiring entity in combating money laundering activities. The Federal Reserve Board also reviews the records of the relevant insured depository institutions under the Community Reinvestment Act of 1997, which we refer to as the “CRA.” In connection with such a review, the Federal Reserve Board will provide an opportunity for public comment on the application and is authorized to hold a public meeting or other proceeding if it determines such meeting or other proceeding would be appropriate.

In addition, a period of 15 to 30 days must expire following approval by the Federal Reserve Board before completion of the merger is allowed, within which period the United States Department of Justice may file

objections to the merger under the federal anti-trust laws. While First Interstate and Northwest believe that the likelihood of objection by the Department of Justice is remote in this case, thereThere can be no assurance that the Department of Justice will not initiate proceedings to block the merger.

Montana Division.Prior approval of the bank merger is required from the Montana Division. The Division requires a30-day public comment period on a bank merger application and may consider any comments received and other factors in considering the bank merger. On January 10, 2019, First Interstate received the approval from the Montana Division.

WashingtonIdaho Department.The bank merger is subject to and must comply with the requirements of the Revised Code of Washington, which we refer to as the “RCW.”Idaho Bank Act. Under the RCW, noticeIdaho Bank Act, an application for approval of the bank merger must be provided to the Washington Idaho

Department, along withwhich includes a copy of the Bank Merger Act application filed with the Federal Reserve Board and the applicable fee.

Additional Regulatory Approvals and Notices.Notifications and/or applications requesting approval may be submitted to various other federal and state regulatory authorities and self-regulatory organizations. The bank merger will result in First Interstate’s acquisitiondirector of Northwest branches located in Idaho and Oregon. Accordingly, First Interstate will submit a notice to the Idaho Department will not approve the application if, among other things: (1) the merger would be detrimental to the safety and soundness of FinanceFirst Interstate Bank or IIBK; (2) First Interstate Bank, its executive officers, directors or principal shareholders do not have a record of sound performance, efficient management, financial responsibility and integrity such that it would be against the Oregon Departmentinterest of Consumerthe depositors, other customers, creditors or shareholders of IIBK, or against the public interest to authorize the merger; or (3) the financial condition of First Interstate Bank or IIBK is such that the financial stability of First Interstate Bank or First Interstate might be jeopardized or the interests of depositors or other customers of First Interstate Bank or First Interstate might be prejudiced; (4) the consummation of the merger will tend to substantially lessen competition within Idaho unless the director finds that the anticompetitive effects of the merger are clearly outweighed by the benefit of meeting the convenience and Business Services.needs of the community to be served; or (5) First Interstate Bank has not established a record of meeting the credit needs of the communities which it services. On January 10, 2019, First Interstate Bank received the approval from the Idaho Department.

The merger cannot proceed in the absence of the requisite regulatory approvals. See “—Conditions to Completing the Merger” and “—Terminating the Merger Agreement.” There can be no assurance that the requisite regulatory approvals will be obtained, and if obtained, there can be no assurance as to the date of any approval. There also can be no assurance that any regulatory approvals will not contain a condition or requirement that causes the approvals to fail to satisfy one or more conditions set forth in the merger agreement and described under “—Conditions to Completing the Merger.”

The approval of any application merely implies the satisfaction of regulatory criteria for approval, which does not include, for example, review of the merger from the standpoint of the adequacy of the merger consideration. Furthermore, regulatory approvals do not constitute an endorsement or recommendation with respect to the merger.

Interests of Certain Persons in the Merger that are Different from Yours

In considering the recommendation of the board of directors of NorthwestIIBK to approve the merger agreement and the merger, you should be aware that Northwest’sIIBK’s executive officers and directors have employment and other compensation agreements or plans that give them financial interests in the merger that are different from, or in addition to, the interests of NorthwestIIBK shareholders generally, which are described below. Northwest’sThe board of directors of IIBK was aware of these interests and considered them, among other matters, in approving the merger agreement and the transactions contemplated by the merger agreement.

Treatment of Restricted Stock Awards.Options.The merger agreement provides that at the effective time of the merger, each unvested share of restrictedall options to purchase IIBK common stock issued by Northwest and outstanding at the effective time of the merger, whether or not vested, will fully vestbe cancelled and, convert intosubject to First Interstate’s receipt of an option surrender agreement, the right to receive the same merger consideration that all other shares of Northwest common stock areholder will be entitled to receive ina lump sum cash payment equal to the merger.

The written demand should be sent to the following address:

not vote in favor of the merger agreement; and

before the time of the vote taken by Northwest shareholders, notify Northwest of the shareholder’s intent to exercise dissenters’ rights.

Except in certain circumstances specified in the WBCA, a shareholder electing to assert dissenters’ rights must generally assert such rights with respect to all shares of Northwest common stock beneficially owned by the shareholder.If a shareholder fails to meet the requirements for assertion of dissenters’ rights such shareholder is not entitled to payment for his or her shares under the WBCA.

If a shareholder properly asserts dissenters’ rights and the proposed merger is consummated, First Interstate, as the surviving corporation in the merger, will send each shareholder who has properly exercised dissenters’

rights a dissenter’s notice, notifying the shareholder of, among other things, the completion of the merger and providing the shareholder instructions for the deposit of certificates representing the dissenter’s Northwest shares and supplying a form for demanding payment.A dissenting shareholder failing to timely demand payment or to deposit certificates representing the dissented Northwest common stock is not thereafter entitled to receive payment for his or her shares under the WBCA.

First Interstate, as the surviving corporation in the merger, is required to pay all dissenting Northwest shareholders who have properly and timely exercised dissenters’ rights, deposited certificates and demanded payment of the “fair value” for their shares of Northwest common stock. The amount of payment is determined by First Interstate and made to dissenting shareholders within time frames specified by the WBCA. If a shareholder is dissatisfied with the amount of the payment determined by First Interstate, such shareholder may notify First Interstate in writing, within 30 days after First Interstate made or offered to make payment, of the shareholder’s own estimate of the fair value of his or her shares and demand payment for such amount (less any payment made by First Interstate). First Interstate may, after the receipt of such demand, elect to pay the additional amount demanded or, within 60 days following receipt of such demand, commence a legal proceeding for a determination of the “fair value” of the shares.

Preferred Stock

First Interstate’s board of directors is authorized, without approval of the holders of First Interstate Class A common stock or First Interstate Class B common stock, to issue preferred stock from time to time in one or more series in such number and with such designations, preferences, powers and other special rights as may be stated in the resolution providing for such preferred stock. The issuance of First Interstate preferred stock with voting, dividend, liquidation and conversion rights could dilute the voting strength of the holders of First Interstate common stock and may assist management in impeding an unfriendly takeover or attempted change in control.

Anti-Takeover Considerations and Provisions of First Interstate’s Articles, Bylaws and Montana Law

A number of provisions of First Interstate’s amended and restated articles of incorporation and bylaws concern matters of corporate governance and the rights of First Interstate’s shareholders. Certain of these provisions may have an anti-takeover effect by discouraging takeover attempts not first approved by First Interstate’s board of directors, including takeovers that may be considered by some of First Interstate’s shareholders to be in their best interests. To the extent takeover attempts are discouraged, temporary fluctuations in the market price of First Interstate Class A common stock, which may result from actual or rumored takeover attempts, may be inhibited. Such provisions also could delay or frustrate the removal of incumbent directors or the assumption of control by shareholders, even if such removal or assumption would be viewed by First Interstate’s shareholders as beneficial to their interests. These provisions also could discourage or make more difficult a merger, tender offer or proxy contest, even if such a transaction could be viewed by First Interstate’s shareholders as beneficial to their interests and could potentially depress the market price of First Interstate Class A common stock. First Interstate’s board of directors believes that these provisions are appropriate to protect First Interstate’s interests and the interests of First Interstate’s shareholders.

Preferred Stock. First Interstate’s board of directors may from time to time authorize the issuance of one or more classes or series of preferred stock without shareholder approval. Subject to the provisions of First

Interstate’s articles of incorporation, limitations prescribed by law and the rules of The Nasdaq Stock Market, if applicable, First Interstate’s board of directors is authorized to adopt resolutions to issue shares, establish the number of shares, change the number of shares constituting any series and provide or change the voting powers, designations, qualifications, limitations or restrictions on shares of First Interstate’s preferred stock, including dividend rights, terms of redemption, conversion rights and liquidation, dissolution andwinding-up preferences, in each case without any action or vote by First Interstate’s shareholders.

One of the effects of undesignated preferred stock may be to enable First Interstate’s board of directors to discourage an attempt to obtain control of First Interstate by means of a tender offer, proxy contest, merger or otherwise. The issuance of preferred stock may adversely affect the rights of holders of First Interstate Class A common stock and First Interstate Class B common stock by, among other things:

 

restricting dividends on either or both classes of common stock;

 

diluting the voting power of either or both classes of common stock;

 

impairing the liquidation rights of either or both classes of common stock;

 

delaying or preventing a change in control without further action by the shareholders; or

 

decreasing the market price of either or both classes of common stock.

Meetings of Shareholders. First Interstate’s bylaws provide that annual meetings of First Interstate’s shareholders will be held at such time as is determined by First Interstate’s board of directors to elect directors and for the transaction of any other business as may come before the annual meeting. First Interstate’s amended and restated articles of incorporation provide that special meetings of shareholders may be called by (1) First Interstate’s board of directors, (2) the Chairman of First Interstate’s board of directors, (3) the Chief Executive

Officer of First Interstate, or (4) a holder, or a group of holders, of common stock holding more than 10% of the total voting power of the outstanding shares of First Interstate capital stock then entitled to vote.

Advance Notice Provisions. First Interstate’s bylaws provide that nominations for directors may not be made by shareholders at any special meeting thereof unless the shareholders intending to make a nomination notifies First Interstate of its intention a specified number of days in advance of the meeting and furnishes to First Interstate certain information regarding itself and the intended nominee. First Interstate’s bylaws also require a shareholder to provide written demand to the First Interstate secretary and must describe the purpose for which the special meeting is to be held. Only business within the purposes described in the notice of the meeting may be conducted at a special meeting. These provisions could delay shareholder actions that are favored by the holders of a majority of First Interstate’s outstanding capital stock until the next shareholders’ meeting.

Filling of Board Vacancies. Unless First Interstate’s board of directors otherwise determines or is otherwise required by applicable law, vacancies and newly created directorships resulting from any increase in the authorized number of directors elected by the shareholders may be filled only by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of First Interstate’s board of directors, or by a sole remaining director. Each such director will hold office until the next election of directors and until such director’s successor is elected and qualified.

Amendment of the First Interstate Amended and Restated Articles of Incorporation. First Interstate’s amended and restated articles of incorporation may be amended in the manner allowed under the MBCA; however, the affirmative vote of the holders of at least 70% of the outstanding shares of the First Interstate Class A common stock, voting separately as a class, is required to amend or repeal any of the provisions in the amended and restated articles of incorporation of First Interstate relating to First Interstate common stock, a change in control transaction or a Class B acquisition transaction (each as defined in the First Interstate amended and restated articles of incorporation).

Amendment of the First Interstate Bylaws. First Interstate’s amended and restated articles of incorporation provide that the First Interstate bylaws may be adopted, altered, amended or repealed by First

Interstate’s board of directors upon the affirmative vote of at least a majority of the directors then in office. First Interstate’s amended and restated articles of incorporation also provide that the bylaws may be adopted, amended, or repealed by a majority of the voting power of the shareholders entitled to vote.

Change in Control. First Interstate’s amended and restated articles of incorporation provide for certain voting thresholds needed to consummate a change in control transaction (as defined in the First Interstate amended and restated articles of incorporation). Accordingly, if First Interstate proposes to engage in a change in control transaction in which holders of First Interstate Class A common stock and First Interstate Class B common stock will receive different consideration, First Interstate will need to obtain, in addition to any shareholder approval required by the MBCA and the First Interstate amended and restated articles of incorporation, the approval of at least 70% of the outstanding shares of First Interstate Class A common stock, voting separately as a single class.

In addition, if First Interstate proposes to merge into another corporation and in the twelve months before such merger the acquiring company acquired any shares of First Interstate Class B common stock, then such merger transaction will require the affirmative vote of 70% of the outstanding shares of First Interstate Class A common stock, voting separately as a single class, unless the holders of the First Interstate Class A common stock and First Interstate Class B common stock receive the same consideration for their shares in the merger and the merger consideration paid is at least equal to the highest amount paid by the acquiring corporation for the First Interstate Class B common stock.

Transactions with Interested Shareholders. First Interstate cannot merge with or sell any material assets to any shareholder of First Interstate Class B common stock unless such transaction is approved by a majority of

the disinterested directors on First Interstate’s board of directors and the holders of a majority of the shares of First Interstate Class A common stock, voting separately as a single class.

No Cumulative Voting.The MBCA provides that shareholders are not entitled to cumulate votes in the election of directors unless First Interstate’s articles of incorporation provide otherwise. First Interstate’s amended and restated articles of incorporation prohibit cumulative voting.

Dual Class Structure

As discussed above, First Interstate Class B common stock is entitled to five votes per share, while First Interstate Class A common stock is entitled to one vote per share. First Interstate Class A common stock is the class of stock to be issued to NorthwestIIBK shareholders in the merger and is the only class of First Interstate’s capital stock that is publicly traded. As of [Record Date],January 14, 2019, members of the Scott family held [•]21,285,014 shares of First Interstate Class B common stock and, therefore, controlled in excess of [•]%71% of the voting power of First Interstate’s outstanding stock. As a result, the Scott family will be able to exert a significant degree of influence or actual control over First Interstate’s management and affairs and over matters requiring shareholder approval, including the election of directors, a merger, consolidation or sale of all or substantially all of First Interstate’s assets and any other significant transaction. This concentrated control will limit the ability of other shareholders to influence corporate matters and the interests of the Scott family may not always coincide with First Interstate’s interests or the interests of other shareholders.

Transfer Agent and Registrar

The transfer agent and registrar for First Interstate’s common stock is American Stock Transfer & Trust Company, LLC.

Restrictions on Ownership

Under the federal Change in Bank Control Act, a notice must be submitted to the Federal Reserve Board if any person (including a company), or group acting in concert, seeks to acquire “control” of a bank holding

company or a bank. An acquisition of “control” can occur upon the acquisition of ten percent or more of the voting stock of a bank holding company or depository institution or as otherwise defined by the Federal Reserve Board. Under the Change in Bank Control Act, the Federal Reserve Board has 60 days from the filing of a complete notice to act, taking into consideration certain factors, including the financial and managerial resources of the acquirer and the anti-trust effects of the acquisition. Any company that so acquires control would then be subject to regulation as a bank holding company.

COMPARISON OF RIGHTS OF SHAREHOLDERS

The rights of shareholders of First Interstate are currently governed by First Interstate’s amended and restated articles of incorporation, bylaws and the MBCA. The rights of shareholders of NorthwestIIBK are currently governed by Northwest’sIIBK’s articles of incorporation, bylaws and the WBCA.Idaho Bank Act. If the merger is completed, NorthwestIIBK shareholders will become First Interstate shareholders and their rights will likewise be governed by First Interstate’s amended and restated articles of incorporation, First Interstate’s bylaws and the MBCA.

The following summary compares the rights of a Northwestan IIBK shareholder and the rights of a shareholder of First Interstate. The following summary is not a complete statement of the differences between the rights of NorthwestIIBK shareholders and the rights of First Interstate shareholders and is qualified in its entirety by reference to the articles of incorporation and bylaws of each corporation. Copies of First Interstate’s amended and restated articles of incorporation and bylaws are on file with the SEC and are available on written request addressed to Kirk D.

Such indemnification is only permitted if (1) the indemnitee acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal proceeding, the indemnitee had no reasonable cause to believe the conduct was unlawful and (2) the indemnification is properly authorized by First Interstate according to the procedures set forth in its bylaws.

Agreement. We express no view as to, and our opinion does not address, the relative merits of the Transaction as compared to any alternative business transactions or strategies, or whether such alternative transactions or strategies could be achieved or are available.

We do not express any opinion as to the value of any asset of the Company whether at current market prices or in the future, or as to the price at which the Company or its assets could be sold in the future.

We are not expressing any opinion as to the impact of the Transaction on the solvency or viability of the Company or Parent or the ability of the Company or Parent to pay their respective obligations when they come due.

We have acted as the Company’s financial advisor in connection with the Transaction 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 Transaction. In addition, the Company has agreed to reimburse our reasonable expenses and indemnify us against certain liabilities arising out of our engagement.

During the two years preceding the date of this letter, we have provided investment banking and other financial services to the Company for which we have received customary compensation. Such services during such period have included serving as the Company’s financial advisor for its acquisition of CenterPointe Community Bank in 2017.

Davidson & Co. and its affiliates may actively trade or hold securities of the Company or Parent for our own accounts or for the accounts of our customers and, accordingly, may at any time hold long or short positions in such securities.

Item 20.

Item 20.

Indemnification of Directors and Officers

Sections35-1-451 through35-1-459 of the Montana Business Corporation Act (the “MBCA”) provide that a corporation may indemnify its directors and officers. In general, the MBCA provides that a corporation must indemnify a director or officer who is wholly successful, on the merits or otherwise, in his or her defense of a proceeding to which he or she is a party because of his or her status as a director or officer of the corporation, against reasonable expenses incurred by the director in connection with the proceeding, unless limited by the articles of incorporation. Pursuant to the MBCA, a corporation may indemnify a director or officer if it is determined that the director or officer engaged in good faith and meets certain standards of conduct. A corporation may not indemnify a director or officer under the MBCA when a director or officer is adjudged liable to the corporation, or when such person is adjudged liable on the basis that personal benefit was improperly received. The MBCA also permits a director or officer of a corporation who is a party to a proceeding to apply to the courts for indemnification or advancement of expenses, unless the articles of incorporation provide otherwise and the court may order indemnification or advancement of expenses under certain circumstances.

First Interstate’s articles provide for the indemnification of directors and officers to the fullest extent permitted by Montana law. First Interstate’s bylaws also provide for the indemnification of directors and officers, including (i) the mandatory indemnification of a director or officer who was wholly successful, on the merits or otherwise, in the defense of any proceeding, (ii) the mandatory indemnification of a director or officer if a determination has been made that such person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal proceeding, with no reasonable cause to believe such person’s conduct was unlawful, (iii) for the reimbursement of reasonable expenses incurred by a director or officer who is party to a proceeding in advance of final disposition of the proceeding, if the standards have been met as set forth in the bylaws. First Interstate has also obtained officers’ and directors’ liability insurance, which insures against liabilities that officers and directors may, in such capacities, incur.Section 35-1-458 of the MBCA provides that a corporation may purchase and maintain insurance on behalf of a director or officer of the corporation against liability asserted against or incurred by such director or officer while serving at the request of the corporation in such capacity, or arising from the individual’s status as a director or officer, whether or not the corporation would have power to indemnify the individual against the same liability under the MBCA.

The foregoing is only a general summary of certain aspects of Montana law and the First Interstate amended and restated articles of incorporation and bylaws dealing with indemnification of directors and officers, and does not purport to be complete. It is qualified in its entirety by reference to the detailed provisions of those sections of the MBCA referenced above and the First Interstate amended and restated articles of incorporation and bylaws.

(2)

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fideoffering thereof.

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

 

II-2


(4)

That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fideoffering thereof.

(5)

That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the registrant undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(6)

That every prospectus (i) that is filed pursuant to paragraph (5) above, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment has become effective, and that for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fideoffering thereof.

In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
