Accompanying this proxy statement is Advanced Energy’s 2003 Annual Report to Stockholders and a form of proxy. All voting on matters presented at the annual meeting will be by paper proxy or by presence in person, in accordance with the procedures described in this proxy statement. Instructions for voting are included in the proxy statement. Your proxy may be revoked at any time prior to the meeting in the manner described in this proxy statement.

  DOUGLAS S. SCHATZ
  Chairman and Chief Executive Officer

This proxy statement and the accompanying proxy card are first being sent to stockholders on or about April 2, 2004.


Table of Contents

GENERAL

      This proxy statement and the accompanying materials are being sent to stockholders of Advanced Energy as part of a solicitation for proxies for use at the 2004 Annual Meeting of Stockholders. The Board of Directors of Advanced Energy is making this solicitation for proxies. By delivering the enclosed proxy card, you will appoint each of Douglas S. Schatz and Michael El-Hillow as your agent and proxy to vote your shares of common stock at the meeting. In this proxy statement, “proxy holders” refers to Messrs. Schatz and El-Hillow in their capacities as your agents and proxies.

      Advanced Energy’s principal executive offices are located at 1625 Sharp Point Drive, Fort Collins, Colorado 80525. The telephone number is (970) 221-4670.

Proposals

      We intend to present two proposals to the stockholders at the meeting:

        1. Election of six directors. The Corporate Governance and Nominations Committee of the Board of Directors of Advanced Energy has proposed that the stockholders re-elect the following directors: Douglas S. Schatz, Richard P. Beck, Robert L. Bratter, Arthur A. Noeth, Elwood Spedden and Gerald M. Starek.
 
        2. Ratification of the appointment of KPMG LLP as independent auditors of Advanced Energy for 2004.

      We do not know of any other matters to be submitted to the stockholders at the meeting. If any other matters properly come before the meeting, the proxy holders intend to vote the shares they represent as the Board of Directors may recommend.

Record Date and Share Ownership

      If you owned shares of Advanced Energy common stock in your name as of the close of business on Monday, March 15, 2004, you are entitled to vote on the proposals that are presented at the meeting. On that date, which is referred to as the “record date” for the meeting, 32,596,050 shares of Advanced Energy common stock were issued and outstanding and were held by approximately 836 stockholders of record, according to the records of American Stock Transfer & Trust Company, Advanced Energy’s transfer agent.

Voting Procedures

      Each share of Advanced Energy common stock that you hold entitles you to one vote on each of the proposals that are presented at the annual meeting. The inspector of the election will determine whether or not a quorum is present at the annual meeting. A quorum will be present at the meeting if a majority of the shares of common stock entitled to vote at the meeting are represented at the meeting, either by proxy or by the person who owns the shares. Advanced Energy’s transfer agent will deliver a report to the inspector of election in advance of the annual meeting, tabulating the votes cast by proxies returned to the transfer agent. The inspector of election will tabulate the final vote count, including the votes cast in person and by proxy at the meeting.

      If a broker holds your shares, this proxy statement and a proxy card have been sent to the broker. You may have received this proxy statement directly from your broker, together with instructions as to how to direct the broker concerning how to vote your shares. Under the rules for Nasdaq-quoted companies, brokers cannot vote on any of the proposals without instructions from you. If you do not give your broker instructions or discretionary authority to vote your shares on one or more of the proposals being considered at the meeting and your broker returns the proxy card without voting on a proposal, your shares will be recorded as “broker non-votes” with respect to the proposals on which the broker does not vote. Broker non-votes will be counted as present for purposes of determining a quorum, but will not be counted as shares entitled to vote. Under Advanced Energy’s Bylaws, most stockholder actions taken at a meeting where a quorum is present are by a majority of the votes cast, excluding abstentions. If you abstain from voting on a proposal, your shares will be

2


Table of Contents

counted as present at the meeting, for purposes of determining a quorum, and entitled to vote, but will have no effect on the outcome of the voting on the proposals described in this proxy statement.

      The following table reflects the vote required for each proposal and the effect of broker non-votes and abstentions on the vote, assuming a quorum is present at the meeting:

         
Effect of Broker Non-Votes
Proposal Vote Required and Abstentions



Election of directors   The six nominees who receive the most votes will be elected   No effect
Ratification of the appointment of KPMG LLP as independent auditors   Majority of the shares present at the meeting (by proxy or in person) and voting “For” or “Against‘ the proposal   No effect

      If any other proposals are properly presented to the stockholders at the meeting, the number of votes required for approval will depend on the nature of the proposal. Generally, under Delaware law the number of votes which may be required to approve a proposal is either a majority of the shares of common stock represented at the meeting and entitled to vote, or a majority of the shares of common stock represented at the meeting and casting votes either for or against the matter being considered. The enclosed proxy card gives discretionary authority to the proxy holders to vote on any matter not included in this proxy statement that is properly presented to the stockholders at the annual meeting.

Costs of Solicitation

      Advanced Energy will bear the costs of soliciting proxies in connection with the annual meeting. In addition to soliciting your proxy by this mailing, proxies may be solicited personally or by telephone or facsimile by some of Advanced Energy’s directors, officers and employees, without additional compensation. We may reimburse our transfer agent, American Stock Transfer & Trust Company, brokerage firms and other persons representing beneficial owners of Advanced Energy common stock for their expenses in sending proxies to the beneficial owners.

Delivery and Revocability of Proxies

      You may vote your shares by marking the enclosed proxy card and mailing it to American Stock Transfer & Trust Company in the enclosed postage prepaid envelope. If you mail your proxy, please allow sufficient time for it to be received in advance of the annual meeting.

      If you deliver your proxy and change your mind before the meeting, you may revoke your proxy by delivering notice to Jay Margulies, our Secretary, at Advanced Energy Industries, Inc., 1625 Sharp Point Drive, Fort Collins, Colorado 80525, stating that you wish to revoke your proxy or by delivering another proxy with a later date. You may vote your shares by attending the meeting in person but, if you have delivered a proxy before the meeting, you must revoke it before the meeting begins. Attending the meeting will not automatically revoke your previously-delivered proxy.

Delivery of Documents to Stockholders Sharing an Address

      If two or more stockholders share an address, Advanced Energy may send a single copy of this proxy statement and other soliciting materials, as well as the 2003 Annual Report to Stockholders, to the shared address, unless Advanced Energy has received contrary instructions from one or more of the stockholders sharing the address. If a single copy has been sent to multiple stockholders at a shared address, Advanced Energy will deliver a separate proxy card for each stockholder entitled to vote. Additionally, Advanced Energy will send an additional copy of this proxy statement, other soliciting materials and the 2003 Annual Report to Stockholders, promptly upon oral or written request by any stockholder to Investor Relations, Advanced Energy Industries, Inc., 1625 Sharp Point Drive, Fort Collins, Colorado 80525; telephone number (970) 221-4670. If any stockholders sharing an address receive multiple copies of this proxy statement, other soliciting

      The Corporate Governance and Nominations Committee was established by the Board of Directors in December 2003, by combining the Governance Committee and Nominating Committee. During 2003, each of the separate Committees met once.

 
Committee Charter and Responsibilities

      The Corporate Governance and Nominations Committee is governed by a written charter, which is available on our website at www.advanced-energy.com.

      The Committee is responsible for:

  •  establishing and administering the procedures for nominating persons to serve as directors;
 
  •  identifying and recommending candidates for nomination to the Board of Directors, consistent with criteria approved by the Board of Directors;
 
  •  considering any nominees recommended by stockholders;
 
  •  determining the appropriate number of authorized directors of Advanced Energy;
 
  •  developing and recommending to the Board of Directors, standards to be applied in making determinations as to the absence of material relationships between Advanced Energy and a director;
 
  •  establishing procedures for the Committee to exercise oversight of the evaluation of the Board of Directors and management;
 
  •  developing and recommending to the Board of Directors a set of corporate governance principles applicable to Advanced Energy, and to review those principles at least annually; and
 
  •  performing any other duties or responsibilities expressly delegated to the Committee by the Board of Directors from time to time relating to the nomination of Board and committee members.

      The Committee will consider any and all director candidates recommended by security holders. If you are a stockholder and wish to recommend a candidate for nomination to the Board of Directors, you should submit your recommendation in writing to the Corporate Governance and Nominations Committee, in care of the Secretary of Advanced Energy at 1625 Sharp Point Drive, Fort Collins, Colorado 80525. Your recommendation should include your name and address, the number of shares of Advanced Energy common stock that you own, the name of the person you recommend for nomination, the reasons for your recommendation, a summary of the person’s business history and other qualifications as a director of Advanced Energy and whether such person has agreed to serve, if elected, as a director of Advanced Energy. Please also see the information under “Proposals of Stockholders” on page 21 of this proxy statement.

      The Committee will apply the same processes and criteria in evaluating director candidates recommended by security holders as it applies in evaluating director candidates recommended by directors, members of management or any other person.

      The Committee does not pay a third party fee to assist in identifying and evaluating director candidates, but Advanced Energy does not preclude the potential for utilizing such services if the Committee deems such services to be necessary or appropriate.

Compensation Committee

 
Composition and Meetings

      The Compensation Committee consists of Messrs. Spedden (Chairman), Noeth and Starek. In 2003, Mr. Noeth was the Chairman of the Committee. Each of the members of the Compensation Committee is a “non-employee director” within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, an “outside director” within the meaning of Section 162(m) under the Internal Revenue Code and an “independent director” within the meaning of Rule 4200(a)(15) of the Marketplace Rules of the Nasdaq Stock Market. The Compensation Committee met three times in 2003.

 
Committee Charter and Responsibilities

      The Compensation Committee is governed by a written charter, which is available on our website at www.advanced-energy.com. The Compensation Committee is responsible for recommending salaries, incentives and other compensation for directors and officers of Advanced Energy, administering Advanced Energy’s incentive compensation and benefit plans for officers and recommending to the Board of Directors policies relating to such compensation and benefit plans.

 
Report on Executive Compensation
 
Compensation Policies

      One of the primary goals in setting compensation policies is to maintain competitive, progressive programs that attract, retain and motivate high-caliber executives, foster teamwork and maximize the long-term success of Advanced Energy by appropriately rewarding such individuals for their achievements. Another goal is to provide an incentive to executives to focus efforts on long-term strategic goals for Advanced Energy by closely aligning their financial interests with stockholder interests. To attain these goals Advanced Energy’s executive compensation program was designed to include base salary, annual incentives and long-term incentives.

      In formulating and administering the individual elements of Advanced Energy’s executive compensation program, planning, implementing and achieving long-term objectives are emphasized to establish performance objectives, evaluate performance and determine actual incentive awards.

 
Compensation Components
 
Base Salary

      The base salaries of executive officers are established after review of relevant data of other executives with similar responsibilities from published industry reports and surveys of similarly situated companies. The market reviewed is comprised of similarly sized high technology companies within and outside Advanced Energy’s industry as described and reported in two independent compensation surveys.

      The base salaries of the Chief Executive Officer and Chief Financial Officer are at approximately 70% of the market data discussed above. All other executives’ base salaries are at levels competitive with the market base salary of executive officers in similar positions.

 
Annual Incentives

      The Compensation Committee determines the range of possible annual bonuses for individual executives based on the same competitive market survey discussed above. Actual bonus payments within this range would be tied to meeting specific corporate and executive performance targets.

      While certain executive’s individual performance targets were met in 2003, the Committee believes that Advanced Energy’s financial performance, principally due to a malaise in the economy in general and the semiconductor industry in particular, makes the payment of an annual bonus to its executives unwarranted.

      The Committee believes that having a higher percentage of the Chief Executive Officer and Chief Financial Officer’s cash compensation derived from their annual incentive payments, when compared to

12


Table of Contents

competitive positions and other executives within Advanced Energy, is prudent given Advanced Energy’s recent financial results and the fact that they are Advanced Energy’s major decision makers.

      When Advanced Energy does achieve financial targets that may qualify executives for annual bonuses as determined by the Committee, the Committee may award bonuses to the Chief Executive Officer and Chief Financial Officer at levels that may bring their total cash compensation at least to an amount competitive with market compensation for similar positions.

 
Stock Options

      The Board of Directors grants stock options under Advanced Energy’s stock option plans to give executives a stake in the long-term performance of Advanced Energy and to focus their attention on maximizing stockholder value. In granting options, the Compensation Committee may consider several factors, including an executive’s individual performance, potential contributions to Advanced Energy, the vesting rates of existing stock options, if any, and options granted to executives in similar positions using the market data discussed above. Vesting schedules also may be used to encourage the long-term retention of executive officers. Options are granted with exercise prices equal to or greater than the fair market value of the common stock subject to the option on the date of grant, as reported on the Nasdaq National Market.

 
Compensation of the Chief Executive Officer

      The compensation of the Chief Executive Officer, Douglas S. Schatz, is based on the policies and procedures applicable generally to executive officers of Advanced Energy. In determining Mr. Schatz’ base salary and bonus, compensation levels for other chief executive officers in high technology firms within and outside the industry were examined. The salary paid to Mr. Schatz for 2003 was below the 35th percentile of compensation paid to chief executive officers of companies of similar size in similar industries, based on independent survey data, because the Committee believes that Mr. Schatz should receive a higher percentage of his cash compensation from his annual incentive payments.

      Given the extended downturn in the semiconductor industry and the negative financial impact it has had on the operating results of Advanced Energy, the Committee determined that Mr. Schatz’ base salary would not be changed in 2004, at this time, nor would he receive a bonus for 2003. In February 2004, the Board awarded Mr. Schatz 85,000 stock options that vest as to 21,250 shares per year over the next four years. In 2003, the exercise prices of certain of Mr. Schatz’ stock options were granted at 110% of the fair market value of the common stock on the date of grant.

      The Committee is currently working with an independent compensation consultant to establish a comprehensive executive compensation program that is market competitive. This study may result in changes to our executive compensation discussed above.

 
Effect of Section 162(m) of the Internal Revenue Code

      Section 162(m) of the Internal Revenue Code of 1986 generally limits to $1 million the corporate deduction for compensation paid to certain executive officers, unless the compensation is “performance-based” (as defined in Section 162(m)). Each of the Board of Directors and the Compensation Committee has carefully considered the potential impact of this limitation on executive compensation and has concluded in general that the best interests of Advanced Energy and the stockholders will be served if certain of Advanced Energy’s stock-based long-term incentives qualify as performance-based compensation within the meaning of Section 162(m). It is the intention of the Board of Directors and Compensation Committee that, so long as it is consistent with the Compensation Committee’s overall compensation objectives, virtually all executive compensation will be deductible for federal income tax purposes.

CERTAIN TRANSACTIONS WITH MANAGEMENT

      Advanced Energy leases its executive offices and certain manufacturing facilities in Fort Collins, Colorado from Prospect Park East Partnership and from Sharp Point Properties, LLC, and has secured future leasing rights for a parcel of land from Sharp Point Properties, LLC. Aggregate payments under such leases for 2003 totaled approximately $2.9 million. Douglas S. Schatz, Chief Executive Officer and Chairman of the Board of Advanced Energy, holds a 26.67% member interest in each of these leasing entities. Mr. Schatz did not participate in the negotiations of these leases. At the time of the negotiations, Advanced Energy compared the lease rates and other terms of similar properties in the Fort Collins area. Advanced Energy believes that the lease rates and other terms of the leases with Prospect Park East Partnership and Sharp Point Properties, LLC are no less favorable to Advanced Energy than could have been obtained from a third-party lessor of similar property.

      During 2003 Advanced Energy leased a condominium in Breckenridge, Colorado from AEI Properties, a partnership in which Mr. Schatz holds a 60% interest. Advanced Energy used the condominium to provide rewards and incentives to its customers, suppliers and employees. Aggregate payments to AEI Properties for 2003 totaled approximately $60,000. The rental rate was determined based upon a comparison of rental rates and other lease terms of similar properties in the area. Advanced Energy believes that the terms of the lease with AEI Properties was no less favorable than could have been obtained from a third party lessor for similar property. In February 2004, this lease agreement was terminated and Advanced Energy will no longer be using the facility.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Section 16(a) of the Securities Exchange Act of 1934 requires Advanced Energy’s executive officers and directors and persons who own more than ten percent of the outstanding common stock (“reporting persons”) to file with the Securities and Exchange Commission an initial report of ownership on Form 3 and changes in ownership on Forms 4 and 5. The reporting persons are also required to furnish Advanced Energy with copies of all forms they file. Based solely on its review of the copies of forms received by it and written representations from the reporting persons, Advanced Energy believes that each of the reporting persons timely filed all reports required to be filed in 2003 or with respect to transactions in 2003.

PROPOSAL NO. 2

RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

      On February 11, 2004, the Audit and Finance Committee approved the continued appointment of KPMG LLP for 2004 as independent auditors. If the stockholders fail to ratify the appointment of KPMG LLP, the Audit and Finance Committee will reconsider its selection.

      The Audit and Finance Committee intends to meet with KPMG LLP in 2004 on a quarterly or more frequent basis. At such times, the Audit and Finance Committee will review the services performed by KPMG LLP, as well as the fees charged for such services.

      A representative of KPMG LLP is expected to be present at the meeting and will have an opportunity to make a statement if he or she so desires. Moreover, the representative is expected to be available to respond to appropriate questions from the stockholders.

      On July 15, 2002, Advanced Energy appointed KPMG LLP to replace Arthur Andersen LLP as its independent accountants. The decision to change public accountants was recommended by Advanced Energy’s Audit and Finance Committee and approved by the Board of Directors.

      In connection with the audit of Advanced Energy’s consolidated financial statements as of and for the two years ended December 31, 2001, and with respect to the subsequent period through March 31, 2002, there were no disagreements with Arthur Andersen LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to their satisfaction, would have caused them to make reference in connection with their opinion on the subject matter of the disagreement.

      Arthur Andersen LLP’s reports on the consolidated financial statements of Advanced Energy as of and for the two years ended December 31, 2001 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

      None of the reportable events described under Item 304(a)(1)(v) of Regulation S-K occurred within the two years ended December 31, 2001, or during the subsequent interim period ended March 31, 2002.

      During the two years ended December 31, 2001 and the subsequent interim period ended March 31, 2002, Advanced Energy did not consult with KPMG LLP regarding any of the matters or events set forth in Item 304(a)(2)(i) or (ii) of Regulation S-K.

Tax Fees

      Tax service fees were for tax services related to Advanced Energy’s global stock-based compensation plans.

Required Vote

      Ratification of the appointment of KPMG LLP as the independent auditors for Advanced Energy for 2004 requires the affirmative (FOR) vote of a majority of the common stock cast on the matter. For purposes of determining the number of votes cast on the matter, only those cast “For” or “Against” are included. Abstentions and broker non-votes are not included.

      The Board of Directors recommends a vote “FOR” the proposed ratification of the appointment of independent auditors.

      The Audit and Finance Committee shall provide assistance to the Board of Directors in fulfilling its responsibility to the stockholders, potential stockholders, and investment community relating to corporate accounting, reporting practices of the Corporation, and the quality and integrity of the financial reports of the Corporation. In so doing, it is the responsibility of the Audit and Finance Committee to maintain free and open means of communication between the Directors, the independent auditors, the internal auditors, and the financial management of the Corporation. The Audit and Finance Committee shall also establish procedures, and maintain easy access to the Audit and Finance Committee, for all employees and consultants to the Corporation to voice concerns and report potential misconduct to the Audit and Finance Committee. The Audit and Finance Committee shall have a clear understanding with management and the independent auditors that the independent auditors are to report directly to the Audit and Finance Committee, and that the independent auditors are ultimately accountable to the Board and the Audit and Finance Committee, as representatives of the Corporation’s stockholders. The Committee shall have a meeting at least quarterly each fiscal year and at any additional time as either the Board or the Committee deems advisable.

III.     Responsibilities

      The Audit and Finance Committee’s policies and procedures in carrying out the Committee’s responsibilities should remain flexible, in order to best react to changing conditions and to ensure to the Directors and stockholders that the corporate accounting and reporting practices of the Corporation are in accordance with all requirements and are of the highest quality.

  •  Review, at least quarterly, with the independent auditors the Corporation’s critical accounting policies and practices and alternative treatments of financial information within generally accepted accounting principles that have been discussed with management.
 
  •  Provide sufficient opportunity for the internal, if applicable, and independent auditors to meet with the members of the Audit and Finance committee without members of Management present.
