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. I look forward to seeing you at the meeting. 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 5, 2002. 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 2002 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 eight directors. The Nominating Committee of the Board of Directors of Advanced Energy has proposed that the stockholders re-elect the current directors: Douglas S. Schatz, G. Brent Backman, Richard P. Beck, Trung T. Doan, Arthur A. Noeth, Elwood Spedden, Gerald M. Starek and Arthur W. Zafiropoulo. 2. Approval of an increase in the number of authorized shares of Advanced Energy common stock from 55 million shares to 70 million shares. 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 18, 2002, 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, 31,892,670 shares of Advanced Energy common stock were issued and outstanding and were held of record by 783 persons, according to the records of American Stock Transfer & Trust Company, Advanced Energy's transfer agent. VOTING 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 how to vote your shares. If you do not give your broker instructions or discretionary authority to vote your shares on one or more of the proposals and your broker returns the proxy card indicating such lack of authority, your shares will be "broker non-votes" with respect to the proposals for which the broker does not have authority to 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. 1 The following table reflects the vote required for each proposal and the effect of broker non-votes on the vote, assuming a quorum is present at the meeting: PROPOSAL VOTE REQUIRED EFFECT OF BROKER NON-VOTES -------- ------------- -------------------------- Election of directors the eight nominees who receive no effect the most votes will be elected Increase in the number of majority of the shares issued same as a vote against authorized shares of common and outstanding as of the the proposal stock record date If you abstain from voting on a proposal, your shares will be counted as present at the meeting, for purposes of determining a quorum, and entitled to vote. As a result, abstentions will have no effect on the election of directors but will have the same effect as a vote against the proposal to increase the number of authorized shares of common stock. 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 required to approve a proposal is a majority of the shares of common stock represented at the meeting. 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 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 2001 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 2001 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.

REPORT OF THE AUDIT AND FINANCE COMMITTEE We are governed by a written charter that was adopted in 1999 and are responsible for: - recommending engagement of Advanced Energy's independent auditors; - reviewing the scope of the audit; - reviewing the independence and performance of Advanced Energy's independent auditors; - evaluating the comments made by the independent auditor with respect to accounting procedures and internal controls and determining whether to bring such comments to the attention of Advanced Energy's management; and - reviewing the internal accounting procedures and controls with Advanced Energy's financial and accounting staff. We also conduct quarterly financial reviews with Advanced Energy's independent accountants prior to the release of financial statements and quarterly reports on Form 10-Q. Management has primary responsibility for Advanced Energy's financial statements and the overall reporting process, including systems of internal controls. The independent auditors audit the annual financial statements prepared by management, express an opinion as to whether those financial statements fairly present the financial position, results of operations and cash flows of Advanced Energy in conformity with generally accepted accounting principles and discuss with us any issues they believe should be raised. We have reviewed Advanced Energy's audited financial statements and met separately with both management and the auditors to discuss and review those financial statements and reports prior to issuance. In addition, we have discussed with the independent auditors the matters outlined in Statement on Accounting Standards No. 61 (Communication with Audit Committees) to the extent applicable. We have received the written disclosures and the letter from the independent accountants required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees). We have also discussed with the independent auditors their independence. Based on our review and discussion of the foregoing matters and information, we recommended to the Board of Directors that the audited financial statements be included in Advanced Energy's 2001 Annual Report on Form 10-K. THE AUDIT AND FINANCE COMMITTEE Gerald M. Starek, Chairman Arthur A.

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. None of the members of the Compensation Committee is or has been an officer or employee of Advanced Energy or any of its subsidiaries. REPORT ON EXECUTIVE COMPENSATION COMPENSATION POLICIES One of the primary goals in setting compensation policies is to maintain competitive, progressive programs to 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 objective is to maintain Advanced Energy's annual executive salaries at levels competitive with the market base salary of executive officers in similar positions. The market reviewed is comprised of similarly sized high technology companies within and outside Advanced Energy's industry as described and reported in the Radford Executive Compensation Survey ("Radford") and in a study conducted for Advanced Energy by SCA Consulting. There are approximately 90 companies in the Radford universe used by the Compensation Committee. In March and June 2001, each of Advanced Energy's executive officers agreed to salary reductions totaling up to 20% of base salary. Effective January 1, 2002, the executive officers' base salaries returned to March 2001 levels. We expect base salaries to remain at current levels until June 2002 at the earliest, except with respect to James Gentilcore, whose responsibilities as Chief Operating Officer have increased substantially. Annual Incentives The Compensation Committee determines the range of possible annual bonuses for individual executives by reviewing a competitive market survey for executives at similar levels and similarly sized companies as described and reported in the Radford Executive Compensation Survey. Actual bonus payments within this range are tied to meeting specific corporate and executive performance targets. Advanced Energy's revenue decreased 46% from 2000 to 2001, and Advanced Energy reported a net loss of $31.4 million in 2001 compared to a net profit of $68.0 million in 2000. These results did not meet the targets for corporate performance in 2001 set by the Compensation Committee and, accordingly, no bonuses were paid for 2001. 10 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, current equity ownership in Advanced Energy and the vesting rates of existing stock options, if any. Vesting schedules also may be used to encourage the long-term retention of executive officers. Options are granted with exercise prices equal to the fair market value of the common stock subject to the option on the date of grant, as reported on the Nasdaq National Market Because the value of an option will increase when Advanced Energy's stock performs well, the Compensation Committee believes stock options serve to align the interests of executive officers closely with those of other stockholders. COMPENSATION OF 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. This information was compared to the performance of such firms relative to Advanced Energy's performance. The salary paid to Mr. Schatz for 2001 was below the 50th percentile of compensation paid to chief executive officers of companies of similar size in similar industries, based on data from the 2001 Radford Executive Compensation Report and 2001 AEA High-Tech Industry Executive Compensation Survey. Mr. Schatz did not receive a bonus for 2001. EFFECT OF SECTION 162(M) OF THE INTERNAL REVENUE CODE Section 162(m) of the Internal Revenue Code of 1986 (the "Tax Code") 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.

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, and G. Brent Backman, a director of Advanced Energy, holds a 6.6% member interest in each of these leasing entities. Aggregate payments under such leases for 2001 totaled approximately $2.23 million. Neither Mr. Schatz nor Mr. Backman participated 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 Fort Collins. 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. Advanced Energy also leases a condominium in Breckenridge, Colorado from AEI Properties, a partnership in which Mr. Schatz holds a 60% interest and Mr. Backman holds a 40% interest. Advanced Energy uses the condominium to provide rewards and incentives to its customers, suppliers and employees. Aggregate payments to AEI Properties for 2001 totaled approximately $47,000. 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 is no less favorable than could have been obtained from a third party lessor for similar property. Richard and Brenda Scholl are both executive officers of Advanced Energy. Richard Scholl's compensation is set forth above under the caption "Executive Compensation." During 2001, Advanced Energy paid to Brenda Scholl a base salary of $153,382 and granted options to her to purchase 6,000 shares of Advanced 15 Energy common stock under the 1995 Stock Option Plan, with an average exercise price of $27.9285 per share. 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 Form 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 2001 or with respect to transactions in 2001. PROPOSAL NO. 2 INCREASE IN NUMBER OF AUTHORIZED SHARES Advanced Energy's Certificate of Incorporation currently authorizes the issuance of 55 million shares of common stock and 1 million shares of preferred stock. As of March 18, 2002, a total of 40,694,790 shares of common stock were outstanding or reserved for issuance as follows: 31,892,670 shares issued and outstanding; 5,948,337 shares reserved for issuance under Advanced Energy's stock option and purchase plans; and 5,839,838 shares reserved for issuance upon conversion of outstanding convertible notes issued by Advanced Energy in November 1999 and September 2001. Advanced Energy proposes to increase the number of shares of common stock that it is authorized to issue to 70 million shares. The number of authorized shares of preferred stock would remain the same. The Board of Directors approved the proposed increase in authorized capitalization at a meeting held on February 12, 2002, subject to stockholder approval. If the stockholders approve the proposal, Paragraph A of Article IV of the Certificate of Incorporation will be amended to read as follows: This corporation is authorized to issue two classes of stock to be designated, respectively, "Common Stock" and "Preferred Stock." The total number of shares which the corporation is authorized to issue is seventy-one million (71,000,000) shares. Seventy million (70,000,000) shares shall be Common Stock, par value $0.001 per share, and one million (1,000,000) shares shall be Preferred Stock, par value $0.001 per share. POTENTIAL USES OF COMMON STOCK Advanced Energy historically has used its common stock principally for the following purposes: - raise capital through equity or convertible debt offerings; - acquire other companies and technologies using common stock; and - adopt benefit plans involving the issuance of common stock to employees, directors and consultants. Advanced Energy has no immediate plans or commitments to issue additional shares of common stock, other than shares that are reserved for issuance as described above. Successfully implementing Advanced Energy's business plans, however, likely will require the availability of authorized but unissued shares. Advanced Energy seeks to increase its product offerings, customer base and total available market, which it historically has done through both internal development and acquisitions. Achieving further increases in these areas through internal development will require Advanced Energy to be able to offer competitive incentives to its employees and prospective employees, including stock options and other stock-based compensation. Acquiring additional companies and technologies also may require the availability of authorized shares of 16 common stock, whether as a currency for the purchase price or to provide incentives to the employees of acquired companies. Both internal development of new products and technologies and acquisitions also may require Advanced Energy to raise working capital in the public and private markets. If required to call a special meeting of stockholders to approve an increase in the authorized capitalization when these or other purposes are identified, Advanced Energy may be prevented from taking advantage of the opportunities because of the time or uncertainty involved in obtaining the requisite approval. DILUTIVE EFFECTS ON CURRENT STOCKHOLDERS If the stockholders approve the proposed increase in the authorized number of shares of common stock, no additional action or authorization by Advanced Energy's stockholders would be necessary prior to the issuance of the shares, unless required by applicable law or the rules of the Nasdaq National Market. When Advanced Energy issues additional shares of common stock, the issuance could have a dilutive effect on earnings per share, as well as the voting power of the current stockholders. Under the Certificate of Incorporation, Advanced Energy's stockholders do not have preemptive rights with respect to the common stock. This means that, when Advanced Energy issues additional shares of common stock, the current stockholders do not have any preferential rights to purchase the shares being issued. POTENTIAL ANTI-TAKEOVER EFFECTS; MANAGEMENT CONTROL The proposed increase in the authorized number of shares of common stock could have an anti-takeover effect under certain circumstances, even though this is not the intention of this proposal. For example, in the event of a hostile attempt to take over control of Advanced Energy, it may be possible for Advanced Energy to issue shares of common stock to dilute the voting power of the other outstanding shares and increase the potential cost to acquire control of Advanced Energy. By potentially discouraging initiation of an unsolicited takeover attempt, the proposed increase in the authorized shares may limit the opportunity for stockholders to dispose of their shares at the higher price generally available in takeover attempts or that may be available under a merger proposal. The issuance of additional shares to parties friendly to Advanced Energy also may have the effect of permitting Advanced Energy's current management, including the current Board of Directors, to retain their positions, and place them in a better position to resist changes that stockholders may wish to make if dissatisfied with the conduct of Advanced Energy's business. REQUIRED VOTE Approval of the proposed amendment to the Certificate of Incorporation to increase the authorized capitalization of Advanced Energy requires the affirmative (FOR) vote of a majority of the shares of common stock issued and outstanding on the record date, which is March 18, 2002. On the record date, there were 31,892,670 shares of common stock issued and outstanding. Unless otherwise instructed on the proxy card, the proxy holders will vote the proxies received by them FOR this proposal. Abstentions and broker non-votes will have the same effect as votes against the proposal.
