PROXY STATEMENT

FOR ANNUAL MEETING OF STOCKHOLDERS

To be held May 29, 2003

INFORMATION CONCERNING SOLICITATION AND VOTING

GENERAL

The enclosed proxy is solicited to the holders of Common Stock, Series D Preferred Stock and Series E Preferred Stock on behalf of the Board of Directors of American Technology Corporation, a Delaware corporation (the “Company”), for use at the Annual Meeting of Stockholders to be held on May 29, 2003, at 2:00 p.m. local time (the “Annual Meeting”), or at any adjournment or postponement thereof, for the purposes set forth herein and in the accompanying Notice of Annual Meeting. The Annual Meeting will be held at the offices of the Company, 13114 Evening Creek Drive South, San Diego, California 92128. The Company intends to mail this proxy statement, the accompanying proxy card and Notice of Annual Meeting on or about April 28, 2003 to all stockholders entitled to vote at the Annual Meeting.

SOLICITATION

The Company will bear the entire cost of solicitation of proxies, including preparation, assembly, printing and mailing of this proxy statement, the proxy and any additional information furnished to stockholders. Copies of solicitation materials will be furnished to banks, brokerage houses, fiduciaries and custodians holding in their names shares of Common Stock beneficially owned by others to forward to such beneficial owners. The Company may reimburse persons representing beneficial owners of Common Stock for their costs of forwarding solicitation materials to such beneficial owners. Original solicitation of proxies by mail may be supplemented by telephone, telegram or personal solicitation by directors, officers or other regular employees of the Company. No additional compensation will be paid to directors, officers or other regular employees for such services.

VOTING RIGHTS AND OUTSTANDING SHARES

Only stockholders of record at the close of business on April 4, 2003 (the “Record Date”) will be entitled to notice of and to vote at the Annual Meeting. At the close of business on April 4, 2003 the Company had outstanding and entitled to vote 15,156,670 shares of Common Stock, 65,000 shares of Series D Preferred Stock and 343,250 shares of Series E Preferred Stock.

Except as provided below, on all matters to be voted upon at the Annual Meeting, each holder of record of Common Stock and Series E of Preferred Stock on the Record Date will be entitled to one vote for each share held, and each holder of Series D Preferred Stock on the Record Date will be entitled to 2.4814 votes for each share held, or an aggregate of approximately 161,291 votes for the Series D Preferred Stock. With respect to the election of directors, stockholders may exercise cumulative voting rights, i.e., each stockholder entitled to vote for the election of directors may cast a total number of votes equal to the number of directors to be elected multiplied by the number of such stockholders shares (on an as-converted basis) and may cast such total of votes for one or more candidates in such proportions as such stockholder chooses. However, no stockholder will be entitled to cumulate votes unless the candidate’s name has been placed in nomination prior to the voting and at least one stockholder has given notice at the meeting, prior to the voting, of his or her intention to cumulate votes. Unless the proxyholders are otherwise instructed, stockholders, by means of the accompanying proxy, will grant the proxyholders discretionary authority to cumulate votes.

All votes will be tabulated by the inspector of election appointed for the meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes. Abstentions will be counted towards the tabulation of votes cast on proposals presented to the stockholders for the purposes of determining the presence of a quorum and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether a matter has been approved. If you sign your proxy card or broker voting instruction card with no instructions, your shares will be voted in accordance with the recommendations of the Board.

REVOCABILITY OF PROXIES

Any person giving a proxy pursuant to this solicitation has the power to revoke it at any time before it is voted. It may be revoked by filing with the Secretary of the Company at the Company’s principal executive office, 13114 Evening Creek Drive South, San Diego, California 92128, a written notice of revocation or a duly executed proxy bearing a later date, or it may be revoked by attending the meeting and voting in person. Attendance at the meeting will not, by itself, revoke a proxy.

STOCKHOLDER PROPOSALS

The deadline for submitting a stockholder proposal for inclusion in the Company’s proxy statement and form of proxy for the Company’s 2004 annual meeting of stockholders pursuant to Rule 14a-8 of the Securities and Exchange Commission is December 30, 2003. Unless a stockholder who wishes to bring a matter before the stockholders at the Company’s 2004 annual meeting of stockholders notifies the Company of such matter prior to March 14, 2004, management will have discretionary authority to vote all shares for which it has proxies in opposition to such matter.

PROPOSAL 1

ELECTION OF DIRECTORS

There are six nominees for the seven Board positions presently authorized in accordance with the Company’s Bylaws. Each director to be elected will hold office until the next annual meeting of stockholders and until his successor is elected and has qualified, or until such director’s earlier death, resignation or removal. Each nominee listed below other than Mr. James Irish is currently a director of the Company. All current directors were elected by the stockholders at the Company’s 2002 annual meeting.

Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the five nominees named below, subject to the discretionary power to cumulate votes. In the event that any nominee should be unavailable for election as a result of an unexpected occurrence, such shares will be voted for the election of such substitute nominee as management may propose.

PROPOSAL TWO

Stockholder ratification of the selection of BDO Seidman, LLP is not required by the Company’s Bylaws or otherwise. However, the Board is submitting the selection of BDO Seidman, LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Board will consider whether or not to retain that firm. Even if the selection is ratified, the Board in its discretion may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interest of the Company and its stockholders.

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the Annual Meeting will be required to ratify the selection of BDO Seidman, LLP. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders for the purpose of determining a quorum and will have the same effect as negative votes.

Other professional services include tax preparation, potential acquisition matters and securities offerings.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934 (the “Act”) requires the Company’s officers, directors and persons who own more than 10% of a class of the Company’s securities registered under Section 12(g) of the Act to file reports of ownership and changes in ownership with the Securities and Exchange Commission (“SEC”). Officers, directors and greater than 10% stockholders are required by SEC regulation to furnish the Company with copies of all Section 16(a) forms they file.

Based solely on a review of copies of such reports furnished to the Company and written representations that no other reports were required during the fiscal year ended September 30, 2002, the Company believes that all persons subject to the reporting requirements pursuant to Section 16(a) filed the required reports on a timely basis with the SEC, except Mr. Croft filed late a Form 5 report disclosing one transaction.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

Introductory Note: The following report is not deemed to be incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933, as amended, or under the Securities Exchange Act of 1934, as amended, except to the extent that the Company specifically incorporates this information by reference, and shall not otherwise be deemed soliciting material or filed under such Acts.

The primary philosophy of the Compensation Committee regarding compensation is to offer packages which reward each of the members of senior management proportionately to each person’s individual performance and to the Company’s overall financial performance and growth during the previous fiscal year.

The Compensation Committee measured individual and team performance on the basis of both quantitative and qualitative factors. The Compensation Committee believes that the components of executive compensation should include base salary, annual and long-term incentive compensation, stock option grants and other benefits summarized below.

Executive compensation

Base salary.    Base salaries are intended to be competitive with market rates and are based on an internal evaluation of the responsibilities of each position. Salaries for executive officers are reviewed on an annual basis. The Committee’s compensation policies are designed to set the Company’s executive compensation, including salary and short-term and long-term incentive programs, at a level consistent with amounts paid to executive officers of comparable companies and consistent with marketplace requirements to attract and retain management personnel with the experience and background to drive the commercialization of the Company’s technologies.

The Committee’s compensation policies are particularly designed to align executive officer and senior management salaries and bonus compensation to the individual’s performance in the short-term and to emphasize compensation from equity, primarily employee stock options, for long-term incentives.

Long term incentives.    The Company’s long-term incentive program consists of a stock option program pursuant to which the Chief Executive Officer and other executive officers (as well as other key employees) are periodically granted stock options at the then fair market value (or higher prices) of the Company’s Common Stock. These option programs are designed to provide such persons with significant compensation based on overall Company performance as reflected in the stock price, to create a valuable retention device through standard three to five year vesting schedules and to help align employees’ and shareholders’ interests. Stock options are typically granted at the time of hire to key new employees, at the time of promotion to certain employees and periodically to a broad group of existing key employees and executive officers.

Chief Executive Officer compensation

Mr. Elwood G. Norris served as our Chief Executive Officer for all of the year ended September 30, 2002, and continued in such position through February 10, 2003. Mr. Norris currently remains active in management of the Company as Chairman of the Board. Prior to his appointment as Chief Executive Officer in September 2000, Elwood G. Norris had been employed by the Company as Chief Technology Officer pursuant to an employment agreement dated September 1, 1997. The agreement has a three-year term, but continues in effect until one party gives thirty-day advance written notice to the other party of an intent to terminate the agreement. Though his duties shifted to those of Chief Executive Officer, Mr. Norris remained employed under the terms of that agreement throughout the year ended September 30, 2002. The agreement provides for a base salary of $10,000 per month, which may in the future be adjusted by the Board of Directors. The agreement also provides that Mr. Norris will participate in bonus, benefit and other incentives at the discretion of the Board of Directors.

In light of the Company’s financial position, Mr. Norris agreed to accept compensation pursuant to his 1997 agreement which the Committee believes is below market for a person of his experience and responsibilities. Accordingly, the compensation paid to Mr. Norris during fiscal 2002 was not specifically performance related.

14

Effective February 10, 2003, the Company entered into a 90-day engagement letter with Mr. James Irish to serve as Chief Executive Officer. Upon completion of the 90-day term the Company and Mr. Irish will enter into a formal three-year employment contract. The three-year employment contract will expire on May 11, 2006. The engagement letter provides for a base salary of $12,500 per month, subject to review by the Board of Directors from time to time in its discretion. The engagement letter also provides that Mr. Irish will participate in bonus, benefit and other incentives at the discretion of the Board of Directors. Mr. Irish was granted 100,000 options under the Company’s 2002 Stock Option Plan. These options vest at a rate of 25 percent at date of grant and 25 percent annually thereafter. The Compensation Committee will consider performance related criteria in connection with the three-year employment agreement to be entered into in May 2003.

Performance-based compensation

Under Section 162(m) of the Internal Revenue Code, compensation payments in excess of $1 million to each person who served as Chief Executive Officer at the end of a taxable year, and to each of the other most highly compensated executive officers whose compensation must be disclosed in SEC filings (collectively, “Covered Employees”), are subject to a limitation of $1 million on the amount the Company may deduct as an ordinary business expense. Certain performance-based compensation is not subject to the limitation on deductibility, but the Company’s option grants prior to January 2001 did not qualify as performance-based compensation. The total taxable compensation to each Covered Employee during the taxable year ended September 30, 2002 from the Company was below $1 million.

The Company issued stock options prior to January 2001 to the Covered Employees and to certain other executive officers who may be Covered Employees in future taxable years. Where these options are non-qualified stock options, or if any Covered Employee makes a disqualifying disposition of an incentive stock option, the amount of the deduction that the Company would otherwise be entitled may be limited to the extent the ordinary income recognized by the Covered Employee upon such exercise or disqualifying disposition, together with all other compensation in a given taxable year, exceeds $1 million. The Compensation Committee intends to attempt to qualify as performance-based compensation future stock option grants to persons who are or may become Covered Employees. However, the Committee may in its discretion award stock options to existing or potential future Covered Employees which do not qualify as performance-based compensation, and the exercise or subsequent disposition of stock acquired from such options may therefore be subject to the limitation on deductibility in Section 162(m).

COMPANY STOCK PRICE PERFORMANCE

Introductory Note: The stock price performance graph below is required by the SEC and will not deemed to be incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933, as amended, or under the Securities Exchange Act of 1934, as amended, except to the extent that the Company specifically incorporates this information by reference, and shall not otherwise be deemed soliciting material or filed under such Acts.

The following graph compares the five-year cumulative total return on the Company’s Common Stock to the total returns of 1) NASDAQ Stock Market and 2) NASDAQ Stock—Electronic & Electrical Equipment & Components, excluding Computer Equipment. This comparison assumes in each case that $100 was invested on September 30, 1997 and all dividends were reinvested. The Company’s fiscal year ends on September 30.

CERTAIN TRANSACTIONS

In September 2001, a family trust for which Mr. Elwood G. Norris serves as trustee purchased $250,000 in principal amount of the Company’s 12% Convertible Subordinated Promissory Notes, and in connection with such purchase, received a warrant to purchase 125,000 shares of Common Stock. The purchase by such trust was on the same terms as those offered to the other purchasers in the same financing. In November 2002, the Company and a majority of the holders of such notes agreed to extend the maturity date of the notes, including the note held by Mr. Norris’ trust, from December 31, 2002 to December 31, 2003.

Certain beneficial owners of more than 5% of the Company’s then outstanding shares of Series D Preferred Stock also held 12% Convertible Subordinates Notes whose maturity dates were extended on the same terms as those described above. These holders were: Canusa Trading, Ltd. ($200,000 principal amount), Jerry E. Polis Family Trust ($250,000 principal amount), Leonard M. Teninbaum Keogh Account ($300,000 principal amount), NGHK Holdings, LLC ($250,000 principal amount), Stifel, Nicolaus Custodian for Jonathan A. Berg ($50,000 principal amount), and James C. Zolin and Josephine M. Zolin (aggregate $150,000 principal amount).

Under the terms of an Assignment of Technology Agreement dated March 2, 1993 and an Addendum Agreement dated December 2, 1996, the Company is also obligated to pay Mr. Norris a 2% royalty on net sales from certain of its technologies, including HyperSonic Sound. The royalty obligation continues until at least March 1, 2007, and for any longer period during which the Company sells products or license technologies subject to any

17

patent assigned to the Company by Mr. Norris under this agreement. The Company has no present plans to market any of the technologies subject to such agreement other than HyperSonic Sound. No royalties were paid under this agreement in the fiscal year ended September 30, 2002. Because HyperSonic Sound entered commercial production and sale during the first quarter of fiscal 2003, it is expected that royalties will be paid to Mr. Norris during fiscal 2003. The amount of such royalties will depend on actual sales.

Certain beneficial owners of more than 5% of the Company’s then outstanding shares of Series D Preferred Stock purchased the Company’s 8% Senior Secured Promissory Notes on September 30, 2002. These holders were: NGHK Holdings, LLC ($1,500,000 principal amount), Sunrise Management Profit Sharing Plan ($50,000 principal amount), Sunrise Capital, Inc. ($100,000 principal amount), and Canusa Trading Ltd. ($350,000 principal amount). These notes were originally due December 31, 2003. The notes are secured by the Company’s accounts receivable, equipment, goods, instruments and inventory. The Company may redeem the notes at any time at its option. The notes are also subject to mandatory redemption upon the closing of a sale of equity securities in an amount exceeding $3,000,000. If the notes are redeemed, the Company must pay to the holders principal and accrued interest through the date of redemption, plus two months’ additional accrued interest. If the notes were redeemed prior to December 31, 2002, the Company agreed to pay accrued interest through February 28, 2003. In February 2003, these notes were amended with the consent of the holders of a majority of the outstanding principal amount to extend the maturity date to December 31, 2004. The notes were further amended to permit the then-applicable amount payable by the Company on redemption to be converted into equity securities. Each of Canusa Trading Ltd., Sunrise Management Profit Sharing Plan and Sunrise Capital, Inc. converted their entire principal amounts to Series E Preferred Stock, and NGHK Holdings, LLC converted $500,000 of its principal amount to Series E Preferred Stock. Each converting holder was paid in cash the amount of accrued interest through April 2003.

Certain beneficial owners of more than 5% of the Company’s then outstanding shares of Series D Preferred Stock purchased the shares of the Company’s Series E Preferred Stock and associated warrants. Each such purchase was on the same terms as those offered to other investors in the Series E round. The $10.00 purchase price of each share of Series E Preferred Stock, increased by $0.60 per share per year, may be converted at the election of a holder one or more times into Common Stock at a conversion price of $3.25. If after September 30, 2003, 90% of the volume weighted average price of the Common Stock for the five trading days prior to conversion (the “Discount Market Price”) is less than $3.25, the conversion price will be reduced to the Discount Market Price; provided, however, that the conversion price cannot be below $2.00 per share. The Series E Preferred Stock may be called by the Company for conversion if the market price of the Common Stock exceeds $9.50 per share for ten consecutive trading days and certain conditions are met. The Series E Preferred Stock will be subject to mandatory conversion on December 31, 2006. Each purchaser of Series E Preferred Stock was also granted a warrant to purchase one and one half shares of Common Stock for each share of Series E Preferred Stock purchased, exercisable until December 31, 2007 at a price of $3.25 per share. Granite Capital LP and Granite Capital II LP purchased 22,500 and 2,500 shares of Series E Preferred Stock, and obtained warrants to purchase 33,750 and 3,750 shares of Common Stock, respectively; and Stifel Nicolaus Custodian for Jonathan Berg IRA purchased 10,000 shares of Series E Preferred Stock and obtained warrants to purchase 15,000 shares of Common Stock. NGHK Holdings, LLC, Canusa Trading, Ltd, Sunrise Management Profit Sharing Plan and Sunrise Capital, Inc. also purchased Series E Preferred Stock and associated warrants via conversion of principal of 8% Senior Secured Notes, as discussed above.

During the fiscal year ended September 30, 2002, the Company paid $121,250 in consulting fees for financial and management advisory services to Sunrise Capital, Inc., which at one time was the beneficial owner of more than 5% of the outstanding Series D Preferred Stock. The Company also issued to Sunrise Capital, Inc. warrants to purchase 100,000 shares of Common Stock at $4.25 per share exercisable until September 30, 2007.
