PROXY STATEMENT

     This Proxy Statement is furnished to the shareholders of First Interstate BancSystem, Inc. (the “Company” or “FIBS”) in connection with the solicitation of proxies of the Company’s shareholders by the Board of Directors to be voted at the Annual Meeting of Shareholders (the “Annual Meeting”) of the Company to be held on May 6, 2005 at 8:00 a.m., Mountain Time, at the Casper Petroleum Club, 1301 Wilkins Circle, Casper, Wyoming 82602, or any adjournment thereof.

     February 28, 2005 (the “Record Date”) is the Record Date for determining the holders of record of shares of the common stock of the Company (the “Common Stock”) entitled to notice of, and to vote at, the Annual Meeting of the Company and any adjournment thereof.

     The mailing of this Proxy Statement to shareholders of the Company commenced on or about March 31, 2005. The Company’s Annual Report on Form 10-K (the “Annual Report”), which includes audited financial statements for the fiscal year ended December 31, 2004, is being mailed to shareholders of the Company simultaneously with this Proxy Statement. All costs incurred in connection with the mailing of this Proxy Statement will be borne by the Company.


INFORMATION CONCERNING SOLICITATION AND VOTING

     Only holders of record of Common Stock at the close of business on the Record Date are entitled to vote at the Annual Meeting. A quorum for the purposes of conducting business at the Annual Meeting is a majority of the outstanding shares of Common Stock entitled to vote. As of the Record Date, the Company had 7,972,608 shares of Common Stock outstanding and entitled to vote. Holders of Common Stock are entitled to one vote per share of Common Stock at the Annual Meeting.

     All proxies that are properly executed and received in a timely manner will be voted in accordance with the instructions noted thereon. Any proxy which does not specify to the contrary will be voted in accordance with the recommendations of the Board of Directors as to the proposals. A shareholder granting a proxy in the form enclosed has the right to revoke it any time before it is voted by filing with the Secretary of the Company an instrument of revocation or by voting or delivering a later executed proxy at the Annual Meeting.

     If a shareholder abstains from voting on any matter, the Company intends to count the abstention as present for purposes of determining whether a quorum is present at the Annual Meeting for the transaction of business. Therefore, abstentions have the same effect as votes against the proposals, except with respect to the election of directors, in which case abstentions have the effect of neither votes cast for nor against specified director nominees. Any broker non-votes will be treated the same as abstentions.

     When a quorum is present in the election of directors, the nominees receiving the greatest number of votes will be elected to the Company’s Board of Directors. With respect to all other matters which may properly come before the Annual Meeting, unless a greater number of votes is required by law or by the Company’s Articles of Incorporation, when a quorum exists a matter will be approved by the shareholders if the votes cast in favor of the matter exceed the votes cast in opposition.

ELECTION OF DIRECTORS

     In accordance with the Company’s amended Bylaws, the number of directors of the Company shall be at least five and not more than eighteen. There are currently seventeen directors.

Board and Committee Matters

     The Company is not listed on any securities quotation system or exchange. The lineal descendants of Homer A. Scott, Sr. and Mildred S. Scott (the “Scott Family”) collectively own approximately 78% of the Company’s common stock and thus control the Company.

     During 2004, the Board of Directors met six times with each director attending at least 83% of the meetings, except Elouise C. Cobell, Homer A. Scott, Jr. and Michael J. Sullivan, each of whom attended 67% of the meetings. The Board of Directors is accountable to shareholders of the Company to build long-term financial performance and value in the Company and to assure that the Company operates consistently with shareholder values and strategic vision. The Board of Directors’ responsibilities include identifying organizational values and vision on behalf of the shareholders of the Company; hiring and evaluating the Chief Executive Officer; ensuring management succession; providing guidance, counsel and direction to management in formulating and evaluating operating strategies and plans; monitoring performance of the Company against established criteria; ensuring prudence and adherence to ethical practices; ensuring compliance with federal and state common and statutory law; ensuring that full and fair disclosure is provided to shareholders, regulators and other constituents and overseeing risk management; exercising all powers reserved to the Company by organizational documents of limited liability companies and partnerships in which the Company is a member or shareholder; and, establishing policies for Board operations. The Company encourages, but does not require, directors and director nominees to attend the annual meeting of shareholders. Seven members of the Board of Directors attended the 2004 Annual Meeting of Shareholders.

     The Company has a Credit Committee, an Executive Committee, a Compensation Committee, a Governance Committee and an Audit Committee, all established by the Board of Directors and each of which consists of members of the Board of Directors.

     Credit Committee. Credit Committee members currently include Richard A. Dorn, William B. Ebzery, Lyle R. Knight, Robert L. Nance, Julie A. Scott, James R. Scott and Thomas W. Scott. The Credit Committee’s primary responsibility is to advise the Chief Executive Officer in the establishment of a loan portfolio that will assure the safety of depositors’ money, earn sufficient income to provide an adequate return on capital and enable communities in the Company’s trade area to prosper. The Credit Committee met twelve times in 2004 with each serving committee member attending at least 83% of the meetings with the exception of James R. Scott who attended 58% of the meetings.

     Executive Committee. Executive Committee members currently include David H. Crum, James W. Haugh, Charles M. Heyneman, Lyle R. Knight, Terry W. Payne, Homer A. Scott, Jr., James R. Scott, Julie A. Scott, Randall I. Scott, Thomas W. Scott, Michael J. Sullivan and Sandra A. Scott Suzor.

The Executive Committee met five times in 2004 with each serving committee member attending at least 80% of the meetings with the exception of Homer A. Scott, Jr. who attended 60% of the meetings.

Scott, Michael J. Sullivan and Sandra A. Scott Suzor.

serving committee member attending at least 83% of the meetings with the exception of Homer A. Scott, Jr. who attended 67% of the meetings. A current copy of the Compensation Committee Charter is maintained on the Company’s website found at www.firstinterstatebank.com.

     Governance Committee. Governance Committee members currently include David H. Crum, James W. Haugh, Charles M. Heyneman, Lyle R. Knight, Terry W. Payne, Homer A. Scott, Jr., James R. Scott, Julie A. Scott, Randall I. Scott, Thomas W. Scott, Michael J. Sullivan and Sandra A. Scott Suzor. The Governance Committee assists the Board in ensuring the Company has an effective and efficient system of governance, including development of criteria for Board membership; recruitment, orientation, development and evaluation of Board members; and, evaluation of services provided to and communications with shareholders. The Governance Committee met four times in 2004 with each serving committee member attending at least 75% of the meetings with the exception of Homer A. Scott, Jr. who attended 50% of the meetings.

     The Board of Directors has determined that Charles M. Heyneman, Lyle R. Knight, Homer A. Scott, Jr., James R. Scott, Julie A. Scott, Thomas W. Scott and Sandra A. Scott Suzor do not meet the independence requirements under Rule 4200(a)(15) of the NASD listing standards. Charles M. Heyneman, Lyle R. Knight and Julie A. Scott received salaries from the Company or its subsidiaries during 2004. Homer A. Scott, Jr., James R. Scott and Thomas W. Scott received salaries or other compensation for services from the Company during the previous three years and Sandra A. Scott Suzor is the daughter of Homer A. Scott, Jr. The Board of Directors has reviewed, assessed the adequacy of and approved a written charter for the Governance Committee. A current copy of the Governance Committee Charter is maintained on the Company’s website.

     The Governance Committee is responsible for identifying, screening and recommending candidates to the Board. The entire Board of Directors is responsible for nominating candidates for election to the Board at the Company’s annual meeting of shareholders and for filling vacancies on the Board that may occur between annual meetings of shareholders.

     When formulating its recommendations for Board of Director nominees, the Governance Committee will consider advice and recommendations offered by the Company’s Chief Executive Officer; shareholders of the Company including members of the Scott Family; and, any outside advisors the Governance Committee may retain.

     The Scott Family, through a family council, makes recommendations to the Governance Committee with respect to candidates for Board of Director membership from the Scott Family. The Governance Committee gives due and significant consideration to recommendations made by the Scott Family. All candidates for the Board of Directors are evaluated on the basis of broad experience, financial acumen, professional and personal accomplishments, educational background, wisdom, integrity, ability to make independent analytical inquires, understanding of the Company’s business environment and willingness to devote adequate time to Board duties. During 2004, non-management directors recommended Martin A. White to the Governance Committee as a candidate for the Board of Directors.

     The Company does not have a formal policy concerning shareholder recommendations of candidates for Board of Director membership. The Board of Directors views that such a formal policy is not necessary given the procedures described above and the Company’s willingness to consider candidates recommended by shareholders. Shareholders may recommend candidates by writing to the Company’s corporate secretary at the Company’s headquarters, 401 N. 31st Street, Billings, Montana 59116, giving the candidate’s name, contact information, biographical data and qualifications. A written statement from the candidate consenting to be named as a candidate and, if nominated and elected, to serve as a director should accompany any such recommendation. Shareholders who wish to nominate a director for election at an annual meeting of the shareholders of the Company must submit a shareholder proposal no later than December 1, 2005 for the 2006 Annual Meeting of Shareholders that is expected to be held on or about May 12, 2006. See “Shareholder Proposals” contained herein.

Principal Accountant Fees and Services

     Effective March 15, 2004, the Company dismissed Ernst & Young LLP as its principal accountants. The Audit Committee of the Board of Directors of the Company approved this action. Ernst & Young LLP’s reports on the Company’s consolidated financial statements for the audit years ended December 31, 2003 and 2002 did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. In connection with the audits of the Company’s consolidated financial statements for the two years ended December 31, 2003, and in the subsequent interim period through March 15, 2004, there were no disagreements with Ernst & Young LLP on any matters of accounting principles or practices, financial statement disclosure, or audit scope or procedures which, if not resolved to the satisfaction of Ernst & Young LLP, would have caused Ernst & Young LLP to make reference to the matter in its report.

     The Company appointed McGladrey & Pullen LLP as the Company’s principal accountants effective March 16, 2004. The Audit Committee approved this action. No consultations or communications, written or oral, regarding the application of accounting principles to specified transactions, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements took place between the Company and McGladrey & Pullen LLP during the two years ended December 31, 2003 or in the subsequent interim period through March 15, 2004.

Communication with the Board

     The Company has not, to date, developed a formal process for shareholder communications with the Board of Directors. The Company believes its current informal process, in which any communication sent to the Board of Directors either generally or in care of the Chief Executive Officer, Corporate Secretary or other corporate officer or director is forwarded to all members of the Board or Directors, has served the Board’s and the shareholders’ needs.

Code of Ethics

     The Company’s Chief Executive Officer, Chief Financial Officer and principal accounting officers or other persons performing similar functions are required to comply with the Company’s Code of Ethics for Chief Executive Officer and Senior Finance Officers (“Financial Code of Ethics”). The purpose of the Financial Code of Ethics is to deter wrongdoing and to promote, among other things, honest and ethical conduct; full, fair, accurate, timely and understandable disclosure in SEC and public filings; compliance with applicable governmental laws, rules and regulations; prompt internal reporting of violations of the Financial Code of Ethics; and, accountability for adherence to such code. Employees may submit concerns or complaints regarding ethical issues on a confidential basis by means of a toll-free telephone hotline or the use of an internet-based reporting system. All concerns and complaints are reported to the Company’s security officer in a summary format for investigation. A current copy of the Financial Code of Ethics is maintained on the Company’s website.

Employment Contracts

     Under an Employment Agreement (the “Agreement”) dated May 18, 1998, Lyle R. Knight is employed as an executive officer of the Company for a ten-year period ending May 18, 2008. During the term of the Agreement, Mr. Knight is entitled to base compensation and additional benefits as are customarily offered to Company executives. Pursuant to the terms of the Agreement, the Company is required to pay specified benefits if Mr. Knight is involuntarily terminated without cause or elects termination in the event of a change in control.

     Upon early termination by the Company without cause, Mr. Knight is entitled to receive severance pay equal to five times his base salary then in effect, bonus compensation and reimbursement of all premiums for group health insurance coverage for a period not exceeding five years. In the event of a change in control, Mr. Knight may elect to terminate the Agreement by giving 90 days written notice at any time on or after the first anniversary, but on or prior to the second anniversary of the change in control. Upon proper termination of the Agreement, Mr. Knight is entitled to severance pay as described above.

     In the event Mr. Knight is unable to perform his duties due to physical or mental disability, the Company may, at its option, terminate the Agreement. Upon termination of the Agreement, Mr. Knight is entitled to reimbursement of all premiums for group health insurance coverage for a period not to exceed five years.

     The Agreement also restricts Mr. Knight’s right to compete against the Company for a period of five years from the date of termination.

Endorsement Split Dollar Benefit

     The Company has obtained life insurance policies covering certain selected executive officers. Under these policies, the Company receives all benefits payable upon death of the insured. An endorsement split dollar agreement has been executed with each of the selected executive officers whereby a portion of the policy death benefit is payable to their designated beneficiary. The endorsement split dollar agreement will provide post retirement coverage for those selected key officers meeting specified retirement qualifications. The Company has entered into this type of endorsement split dollar agreement with Lyle R. Knight, Edward Garding, Terrill R. Moore and Robert A. Jones.

     The Company has obtained a group life insurance policy covering selected officers of the Company’s banking subsidiary. Under the policy, the Company receives all benefits payable upon death of the insured. An endorsement split dollar agreement has been executed with each of insured officers whereby a portion of the policy death benefit is payable to their designated beneficiary if they are employed by the Company at the time of death. The marginal income produced by the policy is used to offset the cost of employee benefit plans of the banking subsidiary. The Company has entered into this type of endorsement split dollar agreement with Lyle R. Knight, Edward Garding, Terrill R. Moore, Robert A. Jones and Ralph K. Cook.

Restricted Stock Plan

     In March 2004, the Company’s Board of Directors approved the 2004 Restricted Stock Award Plan (the “Restricted Stock Plan”). Under the Restricted Stock Plan, Common Stock may be issued at the discretion of the Board of Directors to officers or directors of the Company for no consideration in conjunction with services rendered. Shares issued under the Restricted Stock Plan are subject to terms and conditions determined by the Board of Directors at the date of issuance.

Stock Option Plans

     The Company has two non-qualified stock option plans for executive officers and certain other officers of the Company: the 2001 Plan and the Old Plan. Both the 2001 Plan, adopted by the Company in July 2001, and the Old Plan provide for granting of stock options which may be exercised within a maximum period of ten years from the date of grant. Subsequent to May 2001, the Company discontinued the granting of stock option awards under the Old Plan entirely.

Deferred Compensation Plans

     The Company has two non-qualified deferred compensation plans for a selected group of executive officers and highly compensated employees of the Company: the Executive Non-Qualified Deferred Compensation Plan (the “1998 Plan”) and the Deferred Compensation Plan (the “2000 Plan”). Both plans allow eligible employees, as determined by the Company’s Board of Directors or a committee appointed by the Board of Directors (“Plan Administrator”), to defer a portion of base salary and bonus subject to certain maximum limits set forth by the Plan Administrator. The Company may make discretionary contributions on behalf of a participant for 401(k) plan matching contributions and profit sharing contributions in excess of Internal Revenue Code limitations. In addition, the Company may make other contributions on behalf of a participant at the discretion of the Board of Directors. The deferral account of each participant is credited or debited with investment earnings or losses based upon the performance of the underlying investments selected by the participant from among alternatives selected by the Plan Administrator. Deferral accounts will generally be distributed upon termination of the participant’s service relationship with the Company subject to the participant’s election of predetermined distribution deferral periods or early distribution. Participants may receive distributions in a lump sum or in annual installments over not more than fifteen years.

Compensation Committee Interlocks and Insider Participation in Compensation Decisions

     David H. Crum, James W. Haugh, Charles M. Heyneman, Terry W. Payne, Homer A. Scott, Jr., James R. Scott, Randall I. Scott, Michael J. Sullivan and Sandra A. Scott Suzor serve on the Compensation Committee of the Board of Directors. James R. Scott serves as Vice Chairman of the Board of Directors of the Company, for which he is compensated as described above. Homer A. Scott, Jr. is also compensated for his continuing involvement with the Board of Directors as described above. See “Compensation of Directors and Executive Officers-Director Compensation.” Charles M. Heyneman is employed by the Company’s banking subsidiary. Charles M. Heyneman, James R. Scott, Randall I. Scott and Sandra A. Scott Suzor each have a 2.5% ownership interest in a company that provides professional services to the Company. In addition, James R. Scott is Chairman of the Board of Directors of such company and Charles M. Heyneman and Randall I. Scott each serve as a director of such company. Terry W. Payne is a 42% owner of an insurance agency that provides insurance for the Company. See “Certain Relationships and Related Transactions” below.

     None of the executive officers of the Company served as a member of the compensation committee or as a director of any other company, one of whose executive officers served as a member of the Compensation Committee of the Board of Directors or as a director of the Company during 2004.

Board Compensation Committee Report on Executive Compensation

     Compensation Policy. The Company’s executive compensation policy is designed to establish an appropriate relationship between executive pay and the Company’s annual performance, its long-term growth objectives and its ability to attract and retain qualified executive officers. The Compensation Committee (the “Committee”) attempts to achieve these goals by integrating competitive annual base salaries with (a) bonuses based on corporate performance and on the achievement of specified performance objectives, and (b) key officer restricted stock and stock option awards through the Company’s restricted stock and stock option plans. The Committee believes that cash compensation in the form of salary and bonus provides Company executives with short-term rewards for success in operations. Long-term compensation, through the award of stock options and restricted stock, encourages growth in management stock ownership, which leads to expansion of management’s stake in the long-term performance and success of the Company.

     Base Salary. The Committee approved the 2004 base salary of the Chief Executive Officer and ratified the 2004 compensation of other executive officers as determined by the Chief Executive Officer. In determining or ratifying the base salary of each executive officer, the Committee relied on industry surveys of salaries paid to executive officers of financial institutions with comparable asset size to that of FIBS. The Committee ensures the base salaries of the Company’s executive officers are within a reasonable range of the salaries reflected in such surveys.

Table of Contents

     Bonuses. Annual incentives for the executive officers are intended to reflect the Company’s belief that management’s contribution to return on assets and shareholders’ equity comes from maximizing and improving the quality of earnings. Awards are based on the attainment of specified performance objectives, and the bonus amount is determined as a percentage of the recipient’s base salary. For 2004, executive officers were assigned bonus amounts ranging from 40% to 55% of their base salaries. The varying percentages reflect the Committee’s belief that as an executive officer’s duties and responsibilities in the Company increase, the officer will be increasingly responsible for the performance of the Company. Accordingly, a significant portion of the officer’s compensation should be incentive compensation. Actual bonuses payable depend on the level of achievement of specified performance objectives established for each executive officer. Performance objectives evaluated in determining 2004 executive officer bonuses included attainment of return on equity and related growth in earnings per share goals. In addition, selected executive officers were responsible for continuation of a formal succession planning process, continuation of the strategic planning process and management of capital investments.

     Restricted Stock. Certain executive officers as well as certain other officers of the Company and its subsidiaries were granted restricted stock under the Company’s restricted stock plan. The number of restricted shares issued to each officer was based primarily on the individual’s ability to influence the Company’s growth and profitability. The Committee believes restricted stock awards stimulate the active interest in development and financial success of the Company by those whose performance, contribution and skills are critical to the Company.

     Stock Options. The executive officers as well as certain other officers of the Company and its subsidiaries were granted options under the Company’s stock option plan to purchase a specified number of shares of Common Stock. The number of shares underlying the options granted to each officer was based primarily on the individual’s ability to influence the Company’s long-term growth and profitability as well as the number of options previously granted. The Committee believes stock option grants afford a desirable long-term compensation method because they closely ally the interest of management with shareholder value and the grants of stock options are the best way to directly link the financial interest of management with those of shareholders.

     Compensation of Chief Executive Officer. For the fiscal year ended December 31, 2004, the Company paid Lyle R. Knight, Chief Executive Officer of the Company, a salary of $360,000 and a bonus of $200,000. Mr. Knight’s compensation package was determined to be appropriate by the Committee based on compensation surveys for chief executive officers of financial institutions of comparable size, type and profile, achievement of work plan objectives and improvements in the Company’s financial performance from 2003. Mr. Knight’s compensation package, including bonus, was higher than those granted to other executives of the Company in recognition of his responsibilities and his performance in his position. In establishing Mr. Knight’s compensation package, work plan objectives reviewed included development and implementation of operating plans to achieve earnings goals and capital budgets, continuation of formal succession planning processes, continuation of strategic planning processes and provision of leadership and direction to executive management.

Performance Graph

     The following graph sets forth the cumulative total stockholder return for the Common Stock based on the minority appraised value of the Common Stock compared to an overall stock market index (Russell 2000 Index) and the Company’s peer group index (SNL $1B-$5B Bank Index). The Russell 2000 Index represents a universe of U.S. publicly-owned companies with market capitalizations that are comparable to the

Table of Contents

Company. The SNL $1B-$5B Bank Index is comprised of publicly-owned banks or bank holding companies with total assets between $1 billion and $5 billion. The presented returns are computed assuming the reinvestment of dividends at the frequency with which dividends were paid during the applicable years. The plot points used to prepare the graph were provided by SNL Financial LC, Charlottesville, VA.

     The Common Stock of the Company is not actively traded, and there is no established trading market for the stock. The appraised minority value of the Common Stock represents the estimated fair market valuation of a minority interest in such stock as of a specific date, taking into account adjustments for the lack of marketability of the stock and other factors. In addition, this graph illustrates performance during a limited period of time, and, as a result, may not be indicative of future performance of the Common Stock.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     The Company has had, and expects to have in the future, banking transactions in the ordinary course of business with related parties, including business with directors, officers, stockholders and their associates, on the same terms as those prevailing at the same time for comparable transactions with unrelated persons and that did not involve more than a normal risk of collectibility or present other unfavorable features. To the extent that such transactions consisted of extensions of credit to Company executive officers and directors and to certain members of the Scott Family, such extensions of credit were made in the ordinary course of business, were made on substantially the same terms, including interest rates and collateral on loans, as those prevailing at the same time for comparable transactions with unrelated persons and did not involve more than a normal risk of collectibility or present other unfavorable features. Loans to FIBS’ executive officers, directors and their related interests represented approximately 4.8% of the Company’s shareholders’ equity as of December 31, 2004.

     The Company purchases property and casualty insurance from Payne Financial Group, Inc., an insurance agency in which Terry W. Payne, a director of the Company, has a 42% ownership interest. The Company paid insurance premiums of $339,000 to Payne Financial Group, Inc. in 2004.

Indebtedness of the partnership ($6,204,000 as of December 31, 2004) is recourse to the partners and guaranteed by the Company. The Company paid rent to the partnership of $1,563,000 in 2004.

     The Company leases a Citation 525 aircraft from an entity wholly-owned by Thomas W. Scott, Chairman of the Board. Under the terms of the lease, the Company pays all of the third-party operating expenses of the aircraft, which totaled approximately $204,000 in 2004, net of cost reimbursements of $79,000 from Thomas W. Scott for his personal use of the aircraft. In addition to paying operating expenses, the Company paid Thomas W. Scott’s entity $45,000 for use of the aircraft.

     The Company purchases professional services from a company in which seven directors of Company, including Thomas W. Scott, James R. Scott, Homer A. Scott, Jr., Julie A. Scott, Randall I. Scott, Sandra A. Scott Suzor and Charles M. Heyneman, each have a 2.5% ownership interest. In addition, James R. Scott is Chairman of the Board of Directors of such company and Charles M.
