This Proxy Solicitation
 
We have sent you this proxy statement and the enclosed proxy card because our Board of Directors is soliciting your proxy to vote at the meeting (including any adjournment or postponement of the meeting).
 
  •  This proxy statement summarizes information about the proposals to be considered at the meeting and other information you may find useful in determining how to vote.
 
  •  The proxy card is the means by which you actually authorize another person to vote your shares at the meeting in accordance with your instructions.
 
We will pay the cost of soliciting proxies. Our directors, officers and employees may solicit proxies in person, by telephone or by other means. We will reimburse brokers and other nominee holders of shares for expenses they incur in forwarding proxy materials to the beneficial owners of those shares. We do not currently plan to retain the services of a proxy solicitation firm to assist us in this solicitation.
 
We are mailing this proxy statement and the enclosed proxy card to stockholders for the first time on or about April 21, 2008. In this mailing, we are including a copy of our 2007 Annual Report to Stockholders, which includes our Annual Report on Form 10-K for the year ended December 31, 2007 (excluding exhibits), as filed with the Securities and Exchange Commission, or the SEC. The 2007 Annual Report to Stockholders is not to be regarded as proxy soliciting material or as a communication by means of which any solicitation is to be made.

Who May Vote
 
Holders of record of our common stock at the close of business on April 14, 2008 are entitled to one vote per share of common stock on each proposal properly brought before the annual meeting.
 
A list of stockholders entitled to vote will be available at the annual meeting. In addition, you may contact our Secretary at our corporate offices, located at 50 Webster Road, Oxford, Massachusetts 01540, to make arrangements to review a copy of the stockholder list at those offices, between the hours of 9:00 a.m. and 4:30 p.m., local time, during the ten days before the date of the annual meeting.
 
How to Vote
 
You are entitled to one vote at the meeting for each share of common stock registered in your name at the close of business on April 14, 2008, the record date for the meeting. You may vote your shares at the meeting in person or by proxy.
 
  •  To vote in person, you must attend the meeting, and then complete and submit the ballot provided at the meeting.
 
  •  To vote by proxy, you may:
 
  •  call the toll-free number listed on the accompanying proxy card;
 
  •  visit the Internet site address listed on the accompanying proxy card; or
 
  •  complete, sign and date the accompanying proxy card and return it in the envelope provided.
 
The person named as proxy on the accompanying proxy card was designated by our Board and is one of our officers. All proxies that are properly received by us prior to the meeting, and not revoked, will be voted in accordance with the instructions given in the proxy. If a choice is not specified in the proxy, the shares represented by the proxy will be voted FOR election of the director nominees listed therein, FOR the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 2008 and FOR the approval of the 2008 Employee Stock Purchase Plan. Management is not aware of any other matters that will be presented for consideration at our 2008 annual meeting of stockholders. If any other matter not mentioned in this proxy statement is brought before the meeting, the proxy holder named in the enclosed proxy will have discretionary authority to vote all proxies with respect thereto in accordance with his judgment.
 
If you vote by proxy, you may revoke your proxy at any time before it is exercised by taking one of the following actions:
 
  •  sending written notice to our Secretary at our address set forth in the notice of meeting appearing on the cover of this proxy statement;
 
  •  voting again by proxy on a later date; or
 
  •  attending the meeting, notifying our Secretary that you are present, and then voting in person.
 
Shares Held by Brokers or Nominees
 
If a broker or nominee holds shares of our common stock for you in its name as record holder, then this proxy statement may have been forwarded to you with a voting instruction card, which allows you to instruct the broker or nominee how to vote your shares on the proposals described herein. To vote by proxy, you should follow the directions provided with the voting instruction card. If your shares are held by a broker and you do not provide timely voting instructions, the broker may have discretionary authority to vote your shares on matters which are considered routine. For non-routine matters, if you do not provide instructions, the broker will not vote your shares, which results in a “broker non-vote.” To vote your shares in person, you must obtain a properly executed legal proxy from the record holder of the shares which identifies you as an IPG Photonics Corporation stockholder and authorizes you to act on behalf of the record holder with respect to a specified number of shares.

Quorum Required to Transact Business
 
At the close of business on April 14, 2008, 44,227,241 shares of our common stock were outstanding. Our bylaws require that a majority of our common stock be represented, in person or by proxy, at the meeting in order to constitute the quorum we need to transact business at the meeting. We will count abstentions and broker non-votes in determining whether a quorum exists.
 
Multiple Stockholders Sharing the Same Address
 
If you and other residents at your mailing address own shares of the Company’s common stock through a broker or other nominee, you may have elected to receive only one copy of this proxy statement and our 2007 Annual Report to Stockholders. If you and other residents at your mailing address own shares of the Company’s common stock in your own names, you may have received only one copy of this proxy statement and our 2007 Annual Report to Stockholders unless you provided our transfer agent with contrary instructions. This practice, known as “householding,” is designed to reduce our printing and postage costs. You may promptly obtain an additional copy of this proxy statement, enclosed proxy card and our 2007 Annual Report to Stockholders by sending a written request to IPG Photonics Corporation, Attention: Secretary, 50 Old Webster Road, Oxford, Massachusetts 01540, or by calling our Secretary at (508) 373-1100.

Corporate Governance
 
Corporate Governance Guidelines.  Our Board has adopted Corporate Governance Guidelines (the “Governance Guidelines”) that outline, among other matters, the role and functions of the Board, the responsibilities of various Board committees and the mission of the Board. These Governance Guidelines are available, along with other important corporate governance materials, on our website at www.ipgphotonics.com. We will also provide an electronic or paper copy of these Governance Guidelines, free of charge, upon request made to our Secretary at the address listed on the cover of this proxy statement.
 
The Governance Guidelines provide, among other things, that:
 
  •  a majority of our Board of Directors must be independent;
 
  •  an independent director presides over executive sessions of independent directors;
 
  •  the Board appoints all members of the Board committees;
 
  •  the Audit, Compensation, and Nominating and Corporate Governance Committees consist solely of independent directors;
 
  •  the independent directors meet periodically in executive sessions without the presence of the non-independent directors or members of our management;
 
  •  directors may not serve on the boards of more than three other public companies; and
 
  •  evaluations of the Board and committees are to be conducted annually.
 
The Board regularly reviews changing legal and regulatory requirements, evolving best practices and other developments. The Board may modify the Governance Guidelines and its other corporate governance policies and practices from time to time, as appropriate.

Director Nominations.  The Nominating and Corporate Governance Committee of the Board considers candidates for director nominees proposed by directors and stockholders. This Committee may retain recruiting professionals to assist in identifying and evaluating candidates for director nominees. As set forth in our Governance Guidelines, the Board seeks members from diverse professional backgrounds with a reputation for integrity who do not have professional commitments that might unreasonably interfere with the demands and duties of a board member. Candidates for director are reviewed in the context of the current composition of the Board, the operating requirements of the Company and the long-term interests of the Company’s stockholders. In conducting this assessment, the Board considers diversity, age, skills and such other factors as it deems appropriate given the current needs of the Board and the Company to maintain a balance of knowledge, experience and capability. Candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements, and must be over 21 years of age and possess the highest personal integrity and ethics. The Committee also considers whether the nominee must be independent for Nasdaq purposes.
 
All members of the Board may interview the final candidates. The Nominating and Corporate Governance Committee has adopted a policy under which it will consider nominations by stockholders. The same identifying and evaluating procedures apply to all candidates for director nomination, including candidates submitted by stockholders. The Nominating and Corporate Governance Committee evaluates and interviews potential board candidates.
 
Director Independence.  IPG follows director independence rules under Nasdaq listing standards and SEC rules. Also, our Governance Guidelines require that a majority of our Board of Directors satisfy the independence rules of the Nasdaq Global Market and the SEC. Our Nominating and Corporate Governance Committee has determined that Messrs. Blair, Child, Dalton, Gauthier and Hurley and Dr. Krupke are “independent” as defined by Nasdaq Rule 4200(a)(15). Our Nominating and Corporate Governance Committee has determined that no such member has a relationship that would interfere with the exercise of independent judgment in carrying out his responsibilities as a director.
 
Executive Sessions.  Our independent directors meet privately, without management present, at least four times during the year. These private sessions are generally held in conjunction with the regular quarterly Board meetings. Other private meetings are held as often as deemed necessary by the independent directors. The Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee meet without management present from time to time as they deem necessary.
 
Presiding Independent Director.  In accordance with our Governance Guidelines, an independent director is selected at each meeting of the Board of Directors to preside over executive private meetings of the independent directors. The presiding independent director acts as a liaison between the independent directors and our Chief Executive Officer and communicates to him with respect to matters discussed at executive sessions and agenda items for the Board. The position of presiding independent director rotates at each meeting based upon date of first election to the Board.
 
Director Meetings.  It has been the practice of our Board to hold at least four regular meetings each year. Our Board of Directors met in person or by telephone nine times and acted by unanimous written consent once in 2007. All of our directors attended at least 75% of the aggregate of the total number of meetings held by the Board of Directors and committees on which they served in 2007 except for Mr. Samartsev, who attended 56% of Board meetings.
 
Policy Regarding Board Attendance.  In accordance with our Governance Guidelines, our directors are expected to prepare for, attend and actively participate in meetings of the Board of Directors and meetings of committees on which they serve. Our directors are expected to spend the time needed at each meeting and to meet as frequently as necessary to properly discharge their responsibilities. We encourage members of our Board to attend annual meetings of stockholders, but we do not have a formal policy requiring them to do so. Two of our directors attended our 2007 annual meeting of stockholders.
 
Stock Ownership Guidelines.  The Board adopted stock ownership guidelines in 2007 to more closely align the interests of our directors and executive officers with those of our stockholders. The guidelines

Table of Contents

provide that (i) non-employee directors should maintain an investment in our stock that is at least equal to five times their annual cash Board retainer (excluding committee retainers); (ii) the Chief Executive Officer should maintain an investment in our stock that is at least equal to five times his annual salary; and (iii) other executive officers should maintain an investment that is at least equal to two times their annual salaries. In each case, the investment levels phase in over time and the investment levels are to be achieved no later than five years following the director’s or executive’s initial election or appointment or December 12, 2011, whichever occurs later. All directors and executive officers are currently in compliance with our stock ownership guidelines.
 
Shareholder Communications.  Stockholders wishing to write to the Board or a specified director or a committee of the Board should send correspondence to IPG Photonics Corporation, attention Secretary, 50 Old Webster Road, Oxford, Massachusetts 01540. All written communications received in such manner from stockholders of the Company shall be forwarded to the members or committee of the Board to whom the communication is directed or, if the communication is not directed to any particular member(s) or committee of the Board, the communication shall be forwarded to all members of the Board.
 
Corporate Responsibility
 
Code of Business Conduct.  We have adopted a code of business conduct that applies to all of our directors and employees, including our Chief Executive Officer, Chief Financial Officer and other executive officers. Our code of business conduct includes provisions covering conflicts of interest, business gifts and entertainment, outside activities, compliance with laws and regulations, insider trading practices, antitrust laws, payments to government personnel, bribes or kickbacks, corporate record keeping and accounting records. The code of business conduct is posted on our website at www.ipgphotonics.com.
 
Procedures for Submitting Complaints Regarding Accounting and Auditing Matters.  Our Audit Committee has adopted procedures for the treatment of complaints regarding accounting, internal accounting controls or auditing matters, including procedures for the confidential and anonymous submission by our directors, officers and employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. These procedures are posted on our website at www.ipgphotonics.com.
 
Committees of the Board
 
Our Board has three separate standing committees: the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee. Each committee operates under a written charter adopted by the Board. Copies of the charters of all standing committees are available on our website at www.ipgphotonics.com. We will also provide electronic or paper copies of the standing committee charters free of charge, upon request made to our Secretary.
 
Audit Committee.  The current members of our Audit Committee are Mr. Hurley, who serves as Chairman, Mr. Child and Mr. Gauthier, each of whom is “independent” for Audit Committee purposes under the applicable rules of the Nasdaq Global Market and the SEC. The Nominating and Corporate Governance Committee has determined that Mr. Hurley qualifies as an “audit committee financial expert,” as defined under the Securities Exchange Act of 1934 and the applicable rules of the Nasdaq Global Market. The Audit Committee met in person or by telephone ten times in 2007. The Audit Committee, among other things:
 
  •  appoints, approves the fees of, and assesses the independence of our independent registered public accounting firm;
 
  •  reviews the Audit Committee charter annually and recommends any necessary amendments to such charter to our Board;
 
  •  oversees the work of our independent registered public accounting firm, which includes the receipt and consideration of certain reports from the independent registered public accounting firm;

Director Compensation Plan
 
Our non-employee director compensation plan provides for both cash and equity compensation for our non-employee directors. The principal features of the non-employee director compensation plan are described below. The Board determines director compensation based upon the review and recommendation of the Compensation Committee. The Board adopted the non-employee director compensation plan described below in June 2006 after consideration of an independent director compensation survey and consideration of independent director compensation at several publicly held companies in our industry or with which the directors were familiar that were comparable in size to the Company. In 2006, management gathered director compensation information for comparable companies and developed preliminary recommendations for consideration by the Compensation Committee and the Board.
 
In 2007, the Compensation Committee engaged Radford Surveys + Consulting, a unit of Aon Consulting (“Radford”), an independent compensation consultant, to provide a comprehensive review on compensation for membership on the Board and its committees and to make recommendations from time to time to the Board with regard to such compensation matters. Based upon the compensation assessment practices relative to our peers and other market data provided by Radford, the Board determined not to change director compensation in 2007.

We also reimburse directors for all reasonable out-of-pocket expenses incurred for attending Board and committee meetings. Non-employee directors do not receive any additional payments or perquisites. Directors who are also our employees receive no additional compensation for their service as directors.
 
Our Certificate of Incorporation limits the personal liability of our directors for breaches by them of their fiduciary duties. Our Certificate of Incorporation requires us to indemnify our directors to the fullest extent permitted by the Delaware General Corporation Law. We have also entered into indemnification agreements with all of our directors and we have purchased directors’ and officers’ liability insurance.

Equity Compensation
 
Pursuant to our non-employee director compensation plan that we adopted in 2006, non-employee directors continuing in office after each annual meeting of stockholders receive, effective following the meeting, a grant of stock options to purchase 6,667 shares of our common stock vesting in four equal annual installments. Upon initial election to the Board, each new non-employee director receives a grant of stock options to purchase 20,000 shares of our common stock vesting in four equal annual installments. The exercise price of each of these stock options was not less than the fair market value of our common stock on the date of grant. The non-employee director compensation plan provides that, with respect to options granted after the adoption of the plan, any director who retires after at least eight years of service on the Board will be entitled to full vesting of all options then held by such director. Our non-employee directors stock option plan is described under “Executive Compensation — 2000 Incentive Compensation Plan, 2006 Incentive Compensation Plan and Non-Employee Directors Stock Plan.”
 
PROPOSAL 2: RATIFICATION OF APPOINTMENT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
Deloitte & Touche LLP currently serves as our independent registered public accounting firm and audited our consolidated financial statements for the year ended December 31, 2007. Our Audit Committee has appointed Deloitte & Touche LLP to serve as our independent registered public accounting firm for 2008, and to conduct an integrated audit of our consolidated financial statements for the year ending December 31, 2008 and of our internal control over financial reporting as of December 31, 2008.
 
Our Audit Committee is responsible for selecting and appointing our independent registered public accounting firm, and this appointment is not required to be ratified by our stockholders. However, our Audit Committee has recommended that the Board of Directors submit this matter to the stockholders as a matter of good corporate practice. If the stockholders fail to ratify the appointment, the Audit Committee will reconsider whether to retain Deloitte & Touche LLP, and may retain that firm or another without re-submitting the matter

Table of Contents

to our stockholders. Even if the appointment is ratified, the Audit Committee may, in its discretion, direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and our stockholders.
 
In order to pass, this proposal must receive a majority of the votes cast. We will count abstentions but not broker non-votes when we tabulate votes cast and, as a result, an abstention with respect to this proposal will have the same effect as a vote against the proposal.
 
We expect that representatives of Deloitte & Touche LLP will attend the meeting, will have an opportunity to make a statement if they desire to do so, and will be available to respond to appropriate questions.
 
OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL TO RATIFY THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2008.
 
Fees Paid to Deloitte & Touche LLP
 
The fees for services provided by Deloitte & Touche LLP, member firm of Deloitte Touche Tohmatsu, and their respective affiliates (collectively, “Deloitte & Touche”), to the Company in the last two fiscal years were as follows:
 
                 
    Fees  
Fee Category
  2007     2006  
 
Audit fees
  $ 974,354     $ 1,033,375  
Tax fees
        $ 20,671  
Total Fees
  $ 974,354     $ 1,054,046  
                 
 
Audit fees.  These fees comprise fees for professional services rendered in connection with the audit of the Company’s consolidated financial statements that are customary under auditing standards generally accepted in the United States. Audit fees also include fees for consents and reviews related to SEC filings and quarterly services with respect to the preparation of our unaudited quarterly financial statements. During 2006, the audit fees related to various audit services associated with the initial public offering of our common stock in December 2006 (the “IPO”) totaled $0.8 million.
 
Tax fees.  Fees for tax services consisted of fees for tax compliance services and tax planning and advice services.
 
Tax compliance services are services rendered based upon facts already in existence or transactions that have already occurred to document, compute and obtain government approval for amounts to be included in tax filings and consisted of (i) federal, state and local income tax return assistance, (ii) sales and use, property and other tax return assistance and (iii) assistance with tax audits and appeals.
 
Tax planning and advice are services rendered with respect to proposed transactions or that alter a transaction to obtain a particular tax result. Such services consisted of tax advice related to (i) certain internal legal restructuring actions and other intra-group restructuring actions, (ii) transfer pricing and (iii) other miscellaneous consultations.
 
The Audit Committee has concluded that the provision of the non-audit services listed above is consistent with maintaining the independence of Deloitte & Touche.
 
Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm
 
The Audit Committee pre-approves all audit and permissible non-audit services provided by the independent registered public accounting firm. These services may include audit services, audit-related services and tax services as well as specifically designated non-audit services that, in the opinion of the Audit Committee, will not impair the independence of the independent registered public accounting firm. Pre-

Table of Contents

approval is generally provided for each fiscal year, and any pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. The independent registered public accounting firm and our management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, including the fees for the services performed to date. In addition, the Audit Committee also may pre-approve particular services on a case-by-case basis, as required.
 
AUDIT COMMITTEE REPORT
 
The primary role of the Audit Committee is to assist the Board of Directors in fulfilling its oversight responsibilities by reviewing the financial information proposed to be provided to stockholders and others, the adequacy of the system of internal control over financial reporting and disclosure controls and procedures established by management and the Board, and the audit process and the independent auditors’ qualifications, independence and performance.
 
Management has primary responsibility for the financial statements and is responsible for establishing and maintaining the Company’s system of internal controls and for preparation of the Company’s financial statements. The Company’s independent registered public accounting firm, Deloitte & Touche LLP, is responsible for performing an integrated audit of the Company’s consolidated financial statements and the effectiveness of internal controls over financial reporting in accordance with generally accepted auditing standards and issuing an opinion on the financial statements and the effectiveness of internal controls over financial reporting. The Audit Committee has met and held discussions with management and the Company’s independent auditors, and has also met separately with the Company’s independent auditors, without management present, to review the adequacy of the Company’s internal controls, financial reporting practices and audit process.
 
The Audit Committee has reviewed and discussed the Company’s audited consolidated financial statements for the year ended December 31, 2007 with management and the independent auditors. As part of this review, the Audit Committee discussed with Deloitte & Touche LLP the communications required by generally accepted auditing standards, including those described in Statement on Auditing Standards No. 61, as amended, Communication with Audit Committees, as well as the results of their audit of the effectiveness of internal controls over financial reporting.
 
The Audit Committee has received from Deloitte & Touche LLP a written statement describing all relationships between that firm and the Company that might bear on the auditors’ independence, consistent with Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees. The Audit Committee has discussed the written statement with the independent auditors and has considered whether the independent auditors’ provision of any consultation and other non-audit services to the Company is compatible with maintaining the auditors’ independence.
 
Based on the above-mentioned reviews and discussions with management and the independent auditors, the Audit Committee recommended to the Board of Directors that the Company’s audited consolidated financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2007, as filed with the SEC.

PROPOSAL 3: APPROVAL OF
THE 2008 EMPLOYEE STOCK PURCHASE PLAN
 
Stockholders are being asked to approve our new employee stock purchase plan, the 2008 Employee Stock Purchase Plan (the “Purchase Plan”). The Board has determined that it is in our and our stockholder best interests to have an employee stock purchase plan.
 
A total of 400,000 shares of our common stock will be made available for purchase under the Purchase Plan. In addition, the Purchase Plan provides for an annual increase in the number of shares available for purchase under the Purchase Plan on the first day of each fiscal year, equal to the greater of (i) the number of shares of common stock available under the Purchase Plan as of the last day of the immediately preceding fiscal year and (ii) the lesser of (A) 400,000 shares of common stock and (B) 0.75% of the outstanding shares of common stock on the last day of the immediately preceding fiscal year.
 
Vote Required
 
In order to pass, this proposal must receive a majority of the votes cast. We will count abstentions but not broker non-votes when we tabulate votes cast and, as a result, an abstention with respect to this proposal will have the same effect as a vote against this proposal.
 
Description of the 2008 Employee Stock Purchase Plan
 
The following is a summary of the principal features of the Purchase Plan and its operation. The summary is qualified in its entirety by reference to the Purchase Plan, a copy of which is attached as Appendix A to this proxy statement.
 
General.  The Purchase Plan was adopted by the Board in March 2008, subject to stockholder approval at the Annual Meeting. The purpose of the Purchase Plan is to provide employees with an opportunity to purchase shares of our common stock through accumulated payroll deductions. The Purchase Plan is intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code. Prior to the adoption of the Purchase Plan, we did not have an employee stock purchase plan.
 
Administration.  The Board or committee of independent directors appointed by the Board (referred to as the “Administrator”) administers the Purchase Plan. All questions of interpretation or application of the Purchase Plan are determined by the Administrator and its decisions are final, conclusive and binding upon all participants.
 
Eligibility.  Each of our employees or the employees of our subsidiaries who is an employee and whose customary employment with us or one of our subsidiaries is at least twenty hours per week and more than five months in a calendar year is eligible to participate in the Purchase Plan, subject to the laws pursuant to which our subsidiaries operate. In addition, an employee must be employed by us or by a designated subsidiary for at least six months prior becoming eligible to participate in the Purchase Plan. However, an employee cannot be granted any rights to purchase shares under the Purchase Plan to the extent that (i) immediately after the grant, such employee would own 5% or more of the total combined voting power or value of all classes of our capital stock or the capital stock of one of the subsidiaries, or (ii) the employee’s rights to purchase stock under all of our employee stock purchase plans accrue at a rate that exceeds $25,000 worth of our stock (determined at the fair market value of the shares at the time such option is granted) for each calendar year in which such rights are outstanding. As of December 31, 2007, we and our subsidiaries had approximately 1,300 employees.
 
Offering Period.  The Purchase Plan provides for consecutive, non-overlapping six-month offering periods. Unless the Administrator determines otherwise, the offering periods generally begin on the first trading day on or after January 1 and July 1 of each year, except that the first offering period will commence and end on the trading days selected by the Administrator in accordance with Section 423 of the Internal Revenue Code. At the beginning of each offering period, each participant is deemed to have been granted an option to purchase shares of our common stock. The option is automatically exercised on the last trading day


13


Table of Contents

of the offering period and the amounts deducted and accumulated by the participant are used to purchase shares of our common stock.
 
Participation.  To participate in the Purchase Plan, an eligible employee must authorize payroll deductions pursuant to the Purchase Plan. Such payroll deductions must be in whole percentages not to exceed 10% of a participant’s compensation during the offering period. Once an employee becomes a participant in the Purchase Plan, the employee automatically will participate in each successive offering period until the employee’s employment with us and the designated subsidiaries terminates, or until the employee elects to terminate participation prior to and effective upon the next offering period.
 
Purchase Price.  Shares of our common stock may be purchased under the Purchase Plan at a purchase price equal to 85% of the lesser of the fair market value of the common stock on (i) the first trading day of the offering period or (ii) the last trading day of the offering period. The fair market value of our common stock on any relevant date will be the closing price per share as quoted on the Nasdaq Global Market and reported in The Wall Street Journal or such other source as the Administrator deems reliable.
 
Purchase of Shares.  The number of shares of our common stock that a participant may purchase at the end of an offering period will be determined by dividing the total amount of payroll deductions withheld from the participant’s compensation during that offering period by the purchase price; provided, however, that a participant may not purchase more than a number of shares determined by dividing $12,500 by the fair market value of a share on the first trading day of the offering period. During the offering period, a participant may not discontinue his or her participation in the Purchase Plan and may not decrease or increase the rate of payroll deductions in an offering period.
 
All payroll deductions made for a participant are credited to the participant’s account under the Purchase Plan and are included in our general funds. Funds received by us pursuant to exercises under the Purchase Plan are also used for general corporate purposes. A participant may not make any additional payments into his or her account.
 
Withdrawal.  Generally, a participant may not elect to withdraw from or change his or her payroll deduction election during an offering period.
 
Termination of Employment.  Upon termination of a participant’s employment for any reason, including disability or death, the payroll deductions credited to the participant’s account (to the extent not used to make a purchase of our common stock) will be returned to him or her or, in the case of death, to the person or persons entitled thereto as provided in the Purchase Plan, and the participant’s option will automatically be terminated.
 
Adjustments; Change of Control.  In the event that any change to the outstanding common stock occurs (whether by reason of any recapitalization, stock dividend, stock split, exchange or combination of shares or other change in corporate structure), the Administrator will make adjustments to preserve the benefits under the Plan. These may include appropriate adjustments to:
 
  •  the number and class of securities that may be issued or delivered under the Purchase Plan;
 
  •  the number of securities purchasable per participant during any Purchase Plan offering; or
 
  •  the purchase price per share.
 
It is intended that any adjustments will prevent any dilution or enlargement of rights under the Plan. In the event of various corporate events such as our dissolution or liquidation, or a merger, or a sale of all or substantially all of our assets, the Plan offering which would otherwise be in effect on the date of the event will accelerate and will end on the last pay day before the date of the event. On that date, all outstanding purchase rights will automatically be exercised.
 
Amendment and Termination of the Plan.  The Board may, in its sole discretion, terminate or amend the Plan, but the amendment and termination of the Plan may not adversely affect outstanding purchase rights without the consent of the holders of those rights. The approval of the stockholders is required to alter the aggregate number of shares that may be issued under the Plan (except for the adjustments and annual increases


14


Table of Contents

provided for in the Plan) or the class of employees eligible to receive offerings of shares under the Plan. If we terminate the Purchase Plan, we may end an offering period and accelerate the exercise date of all outstanding purchase rights. We will refund (without interest) any remaining payroll deductions after we terminate the Purchase Plan.
 
New Plan Benefits.  Participation in the Purchase Plan is voluntary and depends on each eligible employee’s election to participate and his or her determination as to the level of payroll deductions. Accordingly, future purchases under the employee stock purchase plan are not determinable. Non-employee directors are not eligible to participate in the Purchase Plan. We cannot determine the benefits that our executive officers and other employees may receive under the Purchase Plan. No purchases have been made under the Purchase Plan since its adoption by the Board.
 
Federal Income Tax Considerations
 
The following summary of the effect of U.S. federal income taxation upon the participants and us with respect to the shares purchased under the Purchase Plan does not purport to be complete, and does not discuss the tax consequences of a participant’s death or the income tax laws of any state or foreign country in which the participant may reside.
 
The Purchase Plan, and the right of participants to make purchases thereunder, are intended to qualify under the provisions of Sections 421 and 423 of the Internal Revenue Code. Under these provisions, no income will be taxable to a participant until the shares purchased under the Purchase Plan are sold or otherwise disposed of. Upon sale or other disposition of the shares, the participant generally will be subject to tax in an amount that depends upon the holding period. If the shares are sold or otherwise disposed of more than two years from the first trading day of the applicable offering period and one year from the applicable date of purchase, the participant will recognize ordinary income measured as the lesser of (i) the excess of the fair market value of the shares at the time of such sale or disposition over the purchase price or (ii) the excess of the fair market value of the shares on the first trading day of the applicable offering period over the purchase price. Any additional gain will be treated as long-term capital gain.
 
If the shares are sold or otherwise disposed of before the expiration of these holding periods, the participant will recognize ordinary income generally measured as the excess of the fair market value of the shares on the date the shares are purchased over the purchase price. Any additional gain or loss on such sale or disposition will be long-term or short-term capital gain or loss, depending on how long the shares have been held from the date of purchase. We generally are not entitled to a deduction for amounts taxed as ordinary income or capital gain to a participant except to the extent of ordinary income recognized by participants upon a sale or disposition of shares prior to the expiration of the holding periods described above.

The stock options were non-qualified stock options to purchase common stock at an exercise price of $1.50 per share. These options vested immediately and expire in March 2010.

COMPENSATION DISCUSSION AND ANALYSIS
 
Compensation Program Objectives and Philosophy
 
We believe that our success depends on the continued contributions of our executive officers. We refer to our Chief Executive Officer, Chief Financial Officer and our three other most highly compensated executive officers, as “Named Executive Officers.” Our executive compensation programs are designed with the philosophy of attracting, motivating and retaining experienced and qualified executive officers and recognizing individual merit and overall business results.
 
In General
 
The objectives of our compensation programs are to:
 
  •  attract and retain talented and experienced executives;
 
  •  motivate and reward executives whose knowledge, skills and performance are critical to achieving strategic business objectives;
 
  •  align the interests of our executive officers and stockholders by motivating executive officers to increase stockholder value;
 
  •  incent future performance through both short-term and long-term financial incentives to build a sustainable company and foster the creation of stockholder value; and
 
  •  foster a shared commitment among executives through establishment of uniform company goals.
 
In order to be effective, we believe our executive compensation program should meet the needs of the Company, our employees and our stockholders. Our policies are also intended to support the attainment of our strategic objectives by tying the interests of our executive officers with those of our stockholders through financial and operational performance goals and equity-based compensation.
 
How We Determine and Assess Executive Compensation
 
Role of the Compensation Committee.  The Compensation Committee of our Board determines, approves and administers the compensation of our executive officers, including our Named Executive Officers. Our Compensation Committee is also responsible for making recommendations to the Board with respect to the adoption of stock and benefit plans. The Compensation Committee may delegate authority whenever it deems appropriate, but it did not do so in 2007.
 
Our Compensation Committee’s policy is to set senior executive pay in accordance with the objectives of the Company’s compensation programs as described above. In our view, the Company’s executive compensation program provides an overall level of compensation opportunity that is competitive with other companies in the laser source and photonics industry, as well as with a broader group of companies of comparable size and complexity that have similar growth rates and international scope. Actual compensation levels may be

Table of Contents

greater or less than average competitive levels provided by similar companies based upon annual and long-term Company performance, as well as individual performance, contributions, skills, experience and responsibilities.
 
Prior to December 2005, the non-employee directors on our Board determined and approved the compensation of our executive officers and negotiated employment agreements to retain key management and provide stability during our critical periods of growth. In December 2005, the Compensation Committee assumed the responsibilities of determining and approving executive officer compensation in addition to the other matters set forth in the Compensation Committee charter. We completed our IPO in December 2006. The Compensation Committee is now comprised of three independent directors: Robert A. Blair, Chair, Michael C. Child and Henry E. Gauthier. Two of the Committee members have experience serving on compensation committees of publicly traded companies and one member was the president and chief executive officer of a publicly traded photonics company.
 
Role of Executive Officers in Compensation Decisions.  The Compensation Committee regularly meets with Dr. Valentin Gapontsev, our Chief Executive Officer, to obtain recommendations with respect to the compensation programs, practices and packages for our Named Executive Officers. Additionally, Mr. Mammen, our Chief Financial Officer, and Mr. Lopresti, our General Counsel, are regularly invited to meetings of the Compensation Committee or otherwise asked to assist the Committee. Such assistance includes providing financial information and analysis for the Compensation Committee and its compensation consultants, taking minutes of the meeting or providing legal advice, developing compensation proposals for consideration, and providing insights regarding our employees (executive and otherwise). The Named Executive Officers will attend portions of Compensation Committee meetings when requested, but leave the meetings as appropriate when matters that will potentially affect them personally are discussed. From time to time, outside legal counsel and the compensation consultant attend Compensation Committee meetings. The Compensation Committee makes decisions regarding Dr. Valentin Gapontsev’s compensation without him present.
 
Role of Compensation Consultant.  In 2007, the Compensation Committee engaged Radford, an independent compensation consultant, to conduct a comprehensive review and analysis of our executive compensation program and to make recommendations. The compensation consultant provides the Compensation Committee with an independent evaluation of an executive compensation, and is available as needed by the Committee to provide advice and counsel. Prior to our IPO in December 2006, the Company did not employ the services of a compensation consultant.
 
This review and analysis was requested by the Compensation Committee. Radford serves at the discretion of the Compensation Committee and does no other work for the Company other than that authorized by the Compensation Committee. The Compensation Committee believes that it is critical for the compensation consultant to confer with management for perspective on the impact of compensation recommendations.
 
Pay Positioning Strategy and Benchmarking of Compensation
 
We strive to position the midpoint of the Company’s target compensation ranges near the 50th percentile of our peers, resulting in targeted total compensation that is competitive within our labor market for performance that meets the objectives established by the Compensation Committee. An individual’s actual salary, non-equity incentive compensation opportunity and equity compensation may fall below or above the target position based on the individual’s experience, seniority, skills, knowledge, performance and contributions. These factors are weighed individually by the Compensation Committee in its judgment, and no single factor takes precedence over others nor is any formula used in making these decisions. The Chief Executive Officer’s review of the performance of his direct reports is carefully considered by the Compensation Committee in making individual pay decisions. Actual pay will be higher or lower than the targeted amounts for each individual based primarily on Company performance.
 
In analyzing our executive compensation program relative to this target market positioning, the Compensation Committee utilizes a comparative analysis of the compensation of our executive officers measured against a group of peer companies selected with the assistance of Radford and management. For 2007, the peer companies included industry peer companies and high-technology companies that recently became


18


Table of Contents

publicly traded (“high-tech companies”). The industry peers were Avanex Corporation, Cognex Corporation, GSI Group Inc., Newport Corporation, Optium Corporation, Palomar Medical Technologies, Inc., and Rofin-Sinar Technologies Inc. The high-technology companies were Acme Packet, Inc, Eagle Test Systems, Inc., First Solar, Inc., Globalstar, Inc., Hittite Microwave Corporation, Nextest Systems Corporation, NTELOS Holdings Corp., Synchronoss Technologies, Inc., Thermage, Inc. and Volcano Corporation.
 
The Compensation Committee reviews the peer group annually to ensure that the comparisons are meaningful. Several factors were considered in selecting the peer group in 2007, the most important of which were:
 
  •  Industry (primarily laser, semiconductor, optical components and related device companies); and
 
  •  Revenue and employee levels (primarily companies with between $50 million and $420 million in annual revenues, and between 150 and 1,400 employees).
 
The Compensation Committee believes that companies that meet these criteria are our most likely competitors for executive talent in our labor markets. Radford also used the Radford Executive Compensation Survey to provide benchmark data used in the compensation analysis.
 
For 2008, Radford recommended that the Compensation Committee approve modifications to the group of peer companies for conducting compensation analyses based on the factors set forth above to better reflect the Company’s current size, industry, strategy and business. In accordance with this recommendation, the Committee removed all of the high-tech companies and Optium Corporation from the peer group, and added Coherent, Inc., Excel Technology, Inc., EXFO Electro-Optical Engineering Inc., FEI Company, FormFactor, Inc., II-IV Incorporated, Measurement Specialties, Inc., Opnext, Inc., SiRF Technology Holdings, Inc. and Veeco Instruments Inc. to the peer group for 2008.
 
Components of Compensation
 
The principal components of our executive officer compensation during 2007 included:
 
  •  Base salary;
 
  •  Annual cash incentives;
 
  •  Long-term equity-based incentive awards;
 
  •  Severance benefits;
 
  •  Retirement savings benefits provided under a 401(k) plan; and
 
  •  Executive perquisites and benefit programs generally available to other employees.
 
These components were selected because the Compensation Committee believes that a combination of salary, incentive pay, benefits and perquisites is necessary to help us attract and retain the executive talent on which our success depends. The annual cash incentives are designed to allow the Compensation Committee to reward performance over a fiscal year and to provide an incentive for executives to appropriately balance their focus on short-term and long-term strategic goals. The fixed components, including salary, benefits and perquisites, are structured to provide a minimum level of security for our executives relative to their day-to-day spending needs and long-term needs for income. The Compensation Committee believes that, when taken together, these components are effective in achieving the objectives of our compensation program and philosophy and are reasonable relative to our strategy of managing total compensation near the 50th percentile of market practices.
 
The Compensation Committee annually reviews the entire compensation program with the assistance of its compensation consultant. However, the Compensation Committee may at any time review one or more components as necessary or appropriate to ensure such components remain competitive and appropriately designed to reward performance. In setting compensation levels for a particular Named Executive Officer, the Committee considers both individual (as described above) and corporate factors.

Table of Contents

Base Salary.  We provide base salary to our Named Executive Officers and other employees to compensate them for services rendered on a day-to-day basis during the fiscal year. Unlike annual cash incentives and long-term equity incentives, base salary is not subject to our performance risk. Prior to our IPO, base salaries for our executives were established based on the scope of their responsibilities and their prior relevant background, training, experience and compensation levels at their prior employment, taking into account market compensation levels and the overall market demand for such executives at the time of hire. Starting in 2007, the Compensation Committee reviewed information provided by its compensation consultant, including information from the Radford Executive Compensation Survey and peer companies’ proxy filings with respect to similarly situated individuals at the peer companies, to assist it in evaluating base salary for each Named Executive Officer. In addition, the Compensation Committee considers each individual’s experience, skills, knowledge and responsibilities. In reviewing the base salary of each Named Executive Officer other than the Chief Executive Officer, the Compensation Committee also considers such individual’s performance review provided by the Chief Executive Officer. With respect to the Chief Executive Officer, the Compensation Committee additionally considers the performance of the Company as a whole.
 
Based upon the information provided by its compensation consultant, the Compensation Committee determined not to change the base salaries of the Named Executive Officers in 2007 from the levels set by the Compensation Committee in 2006. Salaries for our Named Executive Officers were aligned with the 50th market percentile range from the survey of our peers and Radford Executive Compensation Survey data, except for our Chief Financial Officer and General Counsel whose salaries were approximately 20% and 30%, respectively, above the 50th percentile.
 
Annual Cash Incentives under our Non-Equity Incentive Plan.  To focus each executive officer on the importance of the performance of IPG, a significant portion of the individual’s potential short-term compensation is in the form of annual cash incentive pay that is tied to achievement of goals established by the Compensation Committee.
 
Annual cash incentives are granted under our Senior Executive Short-Term Incentive Plan (“STIP”) that was adopted in 2005. The STIP is administered by the Compensation Committee, which has discretion to determine the type of award, whether cash or non-cash, granted pursuant to the terms of the STIP. Historically, the emphasis of the STIP has been on company-wide performance goals in order to foster a shared commitment among executives. Generally, award levels for executives are the same as a percentage of salary, except for the Chief Executive Officer who generally receives awards at a greater percentage of salary than the other officers for achievement of the same performance goals. The Compensation Committee determines who is eligible to receive awards under the STIP, establishes performance goals and objectives for those eligible employees, establishes target awards for each participant for the relevant performance period, and determines what percentage of the target award should be allocated to the achievement of each of the chosen performance targets.
 
In 2007, the Compensation Committee identified two financial performance measures, net sales and earnings before taxes (excluding equity-based compensation expenses and litigation expenses in excess of budgeted amounts), each as determined under the STIP, and assigned a 50% weighting factor to each performance measure. The Compensation Committee chose to focus on revenue growth and pretax profits so that our executive management would be incentivized to deliver the types of growth which benefit our stockholders, namely increasing sales and profitability.
 
Upon the achievement of the objectives for each performance measure determined by the Compensation Committee, the Chief Executive Officer could receive a cash incentive payment ranging from 16% (upon achievement of the minimum level of performance) to 98% (upon achievement of the maximum level of performance) of base salary, and other participants in the STIP could receive a cash incentive payment ranging from 11% (upon achievement of the minimum level of performance) to 65% (upon achievement of the maximum level of performance) of base salary. The financial objectives were the same for all executive officers. The range of possible payout amounts under the STIP for each Named Executive Officer for 2007 is disclosed in the 2007 Grants of Plan-Based Awards table below. Consistent with our pay-for-performance philosophy, no payments for the financial measures would be made if the minimum objectives established by


20


Table of Contents

the Compensation Committee in 2007 were not met. While objectives were intended to be achievable by the Company, a maximum bonus would require very high levels of Company performance. The Compensation Committee believes that the goals are reasonably difficult to achieve, as demonstrated by the fact that the Company has not achieved all of the maximum targets in any year since the STIP was adopted in 2005.
 
The Compensation Committee strove to set aggressive performance objectives, including minimum and maximum targets for net sales from $180 million to $216 million, representing annual growth levels of 26% to 51% from the prior year. The minimum and maximum earnings before taxes targets were set from $48 million to $77 million, representing growth levels of 71% to 174% from the prior year level. After reviewing the Company’s financial performance for 2007, the Compensation Committee awarded the Chief Executive Officer a cash incentive payment equal to approximately 45% of base salary and the other Named Executive Officers a cash incentive payment equal to approximately 30% of base salary. These amounts are set forth in the “Non-Equity Incentive Plan Compensation” column of the 2007 and 2006 Summary Compensation Table below.
 
The Compensation Committee may make adjustments to our overall corporate performance goals and the ways that our actual performance results are calculated that may cause differences between the numbers used for our performance goals and the numbers reported in our financial statements. These adjustments may exclude all or a portion of both the positive or negative effect of external events that are outside the control of our executives, such as natural disasters, litigation or changes in accounting or taxation standards. These adjustments also may exclude all or a portion of both the positive or negative effect of unusual or significant strategic events that are within the control of our executives but that are undertaken with an expectation of improving our long-term financial performance, such as restructurings, acquisitions or divestitures. In 2007, there were no specific individual performance objectives for incentive awards under the STIP. The Compensation Committee may exercise its discretion and take into account individual performance in determining awards in the future. Target total cash compensation levels for all executives was aligned with the 50th market percentile, with the exception of the General Counsel, whose target cash compensation was at the 75th market percentile.
 
Long-term Equity Incentives.  The goal of our equity-based award program is to provide employees and executives with the perspective of an owner who has a financial stake in the success of IPG, thus further increasing alignment with stockholder interest. Long-term incentive awards provide employees with the incentive to stay with us for longer periods of time, which, in turn, provides us with greater stability, and directly links compensation to the long-term performance of the Company. In addition, these awards are less costly to us in the short term than cash compensation. We review long-term equity incentives for our Named Executive Officers and other executives annually.
 
For our Named Executive Officers, our stock option program is based on grants that were individually negotiated in connection with their hiring by the Company and subsequent periodic grants. We have traditionally used stock options as equity compensation because stock options provide a relatively straightforward incentive for our executives, result in less immediate dilution of existing stockholders’ interests and, prior to our adoption of SFAS 123(R), resulted in less compensation expense for us relative to other types of equity awards. Generally, our stock options vest in four equal installments on anniversaries of the dates of grant. Historically, our Chief Executive Officer has not received annual grants of stock options because, as the Company’s largest stockholder, he has the perspective of an owner with a significant financial stake in IPG’s success.
 
In light of a 2006 grant of stock options designed to provide long-term incentives for executives to remain with us following our IPO in December 2006 and the compensation consultant’s determination that equity compensation levels were at the 75th market percentile, the Compensation Committee did not approve the grant of any stock options to executives in 2007. Beginning in 2008, the Compensation Committee will consider an annual equity compensation program based upon 50th market percentile levels. Employees, including the Named Executive Officers, will also be eligible to participate in our 2008 Employee Stock Purchase Plan, if such plan is approved by our stockholders at the 2008 annual meeting of stockholders.

Stock Option Grant Process.  In 2007, the Compensation Committee adopted a stock option grant policy as follows:
 
  •  only the Compensation Committee has the authority to approve equity grants;
 
  •  grants made by the Compensation Committee occur only after discussion at a meeting of the Compensation Committee;
 
  •  equity award grants ordinarily are made by the Compensation Committee only during an open trading window period under our insider trading policy;
 
  •  the grant date ordinarily is within five business days following the first day of the open trading window period, or such other date as the Compensation Committee determines; and
 
  •  the exercise price (if applicable) for all equity awards is the closing price on the date of grant and stock options are granted with an exercise price of no less than fair market value on the date of grant.
 
In general, we issue nonqualified stock options to employees and executives, although we have issued incentive stock options and restricted stock in the past. Options typically have a life of ten years and vest over a four-year period, with the options vesting commencing on the first anniversary of the date of grant.
 
Severance Benefits.  The employment agreements with our Named Executive Officers have severance provisions, the terms of which are described below in the section entitled “Executive Compensation — Potential Payments Upon Termination or Change in Control.” We believe these severance benefits are an essential element of our executive compensation package, are consistent with market practices and assist us in recruiting and retaining talented individuals.
 
Retirement Savings Plans.  Executive officers in the United States are eligible to participate in our 401(k) retirement plan on the same terms as all other U.S. employees. Our 401(k) retirement plan is a tax-qualified plan and thereby subject to certain Internal Revenue Code limitations on the dollar amounts of deferrals and Company contributions that can be made to plan accounts. These limitations apply to our more highly-compensated employees (including the Named Executive Officers). We made matching contributions at a rate of 50% of eligible contributions under the 401(k) retirement plan to our employees, including Named Executive Officers, that participate in the plan as set forth in the 2007 Summary Compensation Table. Our executives outside of the United States participate in government-sponsored retirement programs. We do not maintain a supplementary executive retirement plan or a non-qualified deferred compensation plan for executives or for our directors.
 
Other Compensation.  All of our executives are eligible to participate in our employee benefit plans, including medical, dental, vacation and life insurance. These plans are available to all salaried employees and do not discriminate in favor of executive officers. Benefits are intended to be competitive with the overall market in order to facilitate attraction and retention of high-quality employees. Subject to local customs and the international nature of our business and management, it is generally our policy not to extend significant perquisites to our executives that are not generally available to our employees. Dr. Gapontsev uses Company-owned housing located on the site of our Burbach, Germany facilities and is provided with an automobile leased by the Company for Company business when he visits our German operations. Because of the Company’s multiple locations and the Chief Executive Officer’s travel demands, the Company believes that the use of Company-owned housing and a leased automobile are cost-effective and necessary to enable the Chief Executive Officer to perform his duties while he is in Germany on Company business. The Company also provides Dr. Shcherbakov with an automobile, as it does to other high-ranking employees in Germany.
 
Other Factors Affecting Compensation
 
Tax Deductibility Under Section 162(m).  Section 162(m) of the Internal Revenue Code of 1986, as amended, limits the deductibility for federal income tax purposes of certain compensation paid in any year by a publicly held corporation to its chief executive officer and its three other most highly compensated officers other than its chief financial officer to $1 million per executive (the “$1 million cap”). The $1 million cap does not apply to “performance-based” compensation as defined under Section 162(m) or to compensation


22


Table of Contents

“paid pursuant to certain plans that existed prior to a corporation becoming publicly held”. Historically, none of our executive officers has received annual compensation in an amount that would be subject to limitation under Section 162(m). Once the transition rules are no longer available, it is intended that stock option awards made under the Company’s 2006 Incentive Compensation Plan will qualify as “performance-based” compensation for purposes of Section 162(m). We believe we can continue to preserve related federal income tax deductions, although individual exceptions may arise. The Compensation Committee’s policy with respect to Section 162(m) is to make a reasonable effort to cause compensation to be deductible by the Company while simultaneously providing our executive officers with appropriate rewards for their performance.
 
Accounting Considerations.  The Company considers the accounting implications of all aspects of its executive compensation program. With the adoption of SFAS 123(R), we do not expect accounting treatment of differing forms of equity awards to vary significantly and, therefore, accounting treatment is not expected to have a material effect on our selection of forms of equity compensation. In addition, accounting treatment is just one of many factors impacting plan design and pay determinations. Our executive compensation program is designed to achieve the most favorable accounting and tax treatment possible as long as doing so does not conflict with intended plan design or program objectives.
 
Stock Ownership Guidelines
 
The Board adopted stock ownership guidelines in 2007 to more closely align the interests of our executive officers with those of our stockholders. The guidelines require that the Chief Executive Officer should maintain an investment in our stock that is at least equal to five times his annual salary, and other executive officers should maintain an investment that is at least equal to two times their annual salaries. The ownership levels are phased in over time and the ownership levels are to be achieved no later than five years following the executive’s initial appointment or December 12, 2011, whichever occurs later. All executive officers are currently in compliance with the stock ownership guidelines.
 
COMPENSATION COMMITTEE REPORT
 
The Compensation Committee of the Board of Directors has reviewed and discussed with management the Compensation Discussion and Analysis included in this proxy statement. Based on this review and discussion, the Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in the Company’s proxy statement for the Company’s 2008 annual meeting of stockholders.

Each of these agreements has a two-year term, except for Dr. Gapontsev, whose agreement has a three-year term. The employment agreements automatically renew upon the completion of their initial terms for successive one-year period unless either we or the executive officer gives 180 days’ prior written notice of intent not to extend the agreement. The employment agreements set the annual base salaries for the Named Executive Officers at $360,000, €235,200, $270,000, $270,000 and $240,000, respectively. The agreements entitle these executive officers to participate

in bonus plans, standard insurance plans such as life, accidental death and dismemberment, short-term disability and long-term disability insurance and retirement benefits, such as the 401(k) plan and stock option plans described above, on similar terms and on a similar basis as such benefits are available to executives at similar levels within the organization. The agreements for Drs. Gapontsev, Shcherbakov and BuAbbud require each of them to refrain from competing with us for a period of one year following the termination of their employment with us for any reason and from hiring our employees or soliciting our customers for a period ending eighteen months following the termination of their employment with us for any reason. The severance provisions of the agreements are described below under “Potential Payments Upon Termination or Change in Control”.

2000 Incentive Compensation Plan, 2006 Incentive Compensation Plan and Non-Employee Directors Stock Plan
 
In April 2000, our Board of Directors adopted our 2000 Incentive Compensation Plan, or 2000 plan, and in February 2006, our Board of Directors adopted our 2006 Incentive Compensation Plan, or 2006 plan. The 2000 plan and the 2006 plan have been approved by our stockholders. We reserved 5,833,333 shares under the 2000 plan and 4,000,000 shares under the 2006 plan for the issuance of awards under the plans. Other than the number of shares reserved, the plans are substantially identical. Each plan will terminate ten years after its adoption, unless terminated earlier by our Board of Directors.
 
The 2000 plan and the 2006 plan are administered by the Compensation Committee of our Board of Directors. The Compensation Committee approves awards under the plans, including the exercise price and other terms of each award, subject to the provisions of the plans and has general authority to administer the plans, including to accelerate the vesting of awards and grant awards in replacement of previously granted awards.
 
Each plan authorizes the grant of options to purchase common stock intended to qualify as incentive stock options, as defined in Section 422 of the Internal Revenue Code, and nonstatutory stock options. The plans also provide for awards of restricted stock, stock units, performance shares, performance units, stock appreciation rights and cash awards. The 2000 plan also provides for awards of unrestricted stock.

Table of Contents

Our officers, directors, employees, consultants and advisors are eligible to receive awards under the plans. No participant may receive awards for over 1,333,333 shares of common stock in any calendar year under the 2000 plan, or over 1,666,667 shares of common stock in any calendar year under the 2006 plan.
 
In June 2006, our Board of Directors adopted our Non-Employee Directors Stock Plan (the non-employee director plan) and in October 2006 the non-employee director plan was approved by our stockholders. Only our non-employee directors are eligible to receive awards under the non-employee director plan. We reserved 166,666 shares for issuance under the non-employee director plan. The maximum number of shares that may be issued or transferred under the plan equals 0.75% of the number of outstanding shares of our Company (on a fully diluted basis) at the end of the plan year preceding the then-current plan year, or on January 1, 2006, whichever is greater, up to a maximum of 166,666 shares. The non-employee director plan will terminate ten years after its adoption, unless terminated earlier by our Board of Directors.
 
The non-employee director plan is administered by our Compensation Committee. The Compensation Committee approves awards under the plan, including the exercise price and other terms of each award, subject to the provisions of the plan and has general authority to administer the plan, including to grant awards in replacement of other awards. The exercise price must be at least equal to the fair market value of our common stock on the date of grant.
 
The non-employee director plan authorizes the grant of options to purchase common stock that are not intended to qualify as incentive stock options, as defined in Section 422 of the Code. The plan also provides for awards of stock appreciation rights, stock units, stock awards and cash awards.
 
Each of the 2000 plan and the 2006 plan provides that, upon a change in control of our company, the Compensation Committee may, in its sole discretion:
 
  •  accelerate the time for exercise or payout of all outstanding awards;
 
  •  cancel the award after notice to the holder of an outstanding award as long as the holder receives a payment equal to the difference between the fair market value of the award on the date of the change in control and the exercise price per share, if any, of such award; or
 
  •  provide that all outstanding awards will be either assumed by the entity that acquires control or substituted for similar awards by such entity.
 
In addition, in the event that the 2000 plan or 2006 plan is terminated due to a merger or acquisition of our company, the Compensation Committee has the right, but not the obligation, to direct the repurchase of outstanding stock options at a price equal to the fair market value of the shares subject to the repurchased options less the exercise price per share.
 
The non-employee director plan provides that awards become fully vested and exercisable upon a change in control. For these purposes, a “change in control” means the occurrence of any of the following:
 
  •  any person becomes a beneficial owner of our securities representing at least 50% of the combined voting power of our then-outstanding securities;
 
  •  persons who, at the beginning of any period of two consecutive years, were members of the Board of Directors cease to constitute a majority of the Board of Directors unless the election or nomination for election by the stockholders of each new director during that two-year period is approved by at least two-thirds of the incumbent directors then still in office;
 
  •  the occurrence of a merger, sale of all or substantially all of our assets, cash tender or exchange offer, contested election or other business combination under circumstances in which our stockholders immediately prior to such merger or other such transaction do not, after such transaction, own shares representing at least a majority of our voting power or the surviving or resulting corporation, as the case may be; or
 
  •  our stockholders approve a complete liquidation.

(1) The value realized is based upon the difference between the sale price (with respect to non-qualified stock options) or the reported closing sale price on the date of sale (with respect to incentive stock options) and the exercise price.
 
Pension Benefits
 
None of our Named Executive Officers participate in or have account balances in qualified or nonqualified defined benefit pension plans sponsored by us. The Compensation Committee may elect to adopt qualified or nonqualified defined benefit pension plans in the future if the Compensation Committee determines that doing so is in our best interests.
 
Nonqualified Deferred Compensation
 
None of our Named Executive Officers participate in or have account balances in nonqualified defined contribution plans or other nonqualified deferred compensation plans maintained by us. The Compensation Committee may elect to provide our officers and other employees with nonqualified defined contribution or other nonqualified deferred compensation benefits in the future if the Compensation Committee determines that doing so is in our best interests.
 
Potential Payments Upon Termination or Change in Control
 
Pursuant to the employment agreements, each Named Executive Officer, except Dr. Gapontsev, would continue to receive 100% of his base salary for a period of twelve months from the date of termination if the Company terminates his employment without cause or if the officer terminates employment for good reason. In the event that Dr. Gapontsev terminates his employment for good reason, he would receive 100% salary continuation for the longer of one year or the remaining term of his agreement, but in no event longer than two years. The definition of “good reason” for each Named Executive Officer includes the failure of the executive to maintain his specific executive position, a material reduction in the executive’s authorities and responsibilities, a relocation of the offices of the executive of more than 35 miles or a material breach by us of the executive’s employment agreement. Under the employment agreements, we are not obligated to make any cash payments to these executives if their employment is terminated by us for cause or by the executive not for good reason. A change in control does not affect the amount of any cash severance payments.
 
The stock options awarded to the Named Executive Officers do not provide for automatic accelerated vesting if the Company terminates employment without cause, if the employee terminates employment for good reason or upon a change in control. Each of the 2000 Incentive Compensation Plan and the 2006 Incentive Compensation Plan provides that, upon a change in control of the Company, the Compensation Committee, in its sole discretion, may (i) accelerate the time for exercise or payout of all outstanding awards, (ii) pay the holder equal to the difference between the fair market value of the award on the date of the change in control and the exercise price per share, if any, of such award or (iii) provide that all outstanding awards will either be assumed by the entity that acquires control or substituted for similar awards by such entity.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
 
Transactions with IP Fibre Devices
 
We sublease office space in London, England from IPFD and reimburse IPFD for general and administrative expenses. We paid IPFD $116,000 in 2007 relating to the sublease. Dr. Valentin P. Gapontsev, Dr. Denis Gapontsev, our Vice President, Research and Development, Dr. Eugene Shcherbakov, a member of our Board of Directors and Managing Director of IPG Laser, and Igor Samartsev, a member of our Board of Directors and Acting General Manager of NTO IRE-Polus, own 53%, 15%, 8% and 8%, respectively, of IPFD, which owns 8,004,002 shares of our common stock, which represents approximately 18% of our outstanding common stock. IPFD is a limited company organized under the laws of the United Kingdom. Its primary purpose is to hold financial and other assets and it does not engage in any business that is competitive to ours.
 
Transactions with NTO IRE-Polus
 
We own 58.6% of NTO IRE-Polus, our Russian subsidiary. Dr. Valentin P. Gapontsev and Igor Samartsev own 26.7% and 4.9%, respectively, of NTO IRE-Polus. The remaining 9.8% of NTO IRE-Polus is owned by certain of NTO IRE-Polus’s other current and former employees and unaffiliated third parties. NTO IRE-Polus provides us with low-cost contract manufacturing capacity and sells products to customers in Russia and neighboring countries. We acquired our majority ownership interest directly from NTO IRE-Polus in 2001. At such time, we agreed to invest up to $5.0 million in NTO IRE-Polus, subject to our approval of the business plan of NTO IRE-Polus. We have invested the full $5.0 million as of March 2007. This investment did not increase our equity interest in NTO IRE-Polus. The investment has been used solely for equipment purchases and the development of additional manufacturing capacity. All profits earned by NTO IRE-Polus to date have been re-invested in NTO IRE-Polus and there have been no distributions to stockholders of NTO IRE-Polus since we purchased our majority interest. The charter of NTO IRE-Polus provides that the stockholders of NTO IRE-Polus may each quarter, once a half-year, or once a year approve net profit distributions to the stockholders in proportion to their shares in NTO IRE-Polus’s authorized capital.
 
In the ordinary course of business, we sell components to NTO IRE-Polus. NTO IRE-Polus also sells us components, tools and equipment that we use in our production and testing. Sales by us to NTO IRE-Polus were approximately $12.1 million in 2007, and sales by NTO IRE-Polus to us were approximately $15.8 million in 2007.
 
In 2007, we guaranteed a Euro 3.0 million line of credit to NTO IRE-Polus from Duetsche Bank AG. We also guarantee the lines of credit to our other subsidiaries. Dr. Valentin P. Gapontsev and Mr. Samartsev agreed to reimburse the Company a pro rata portion of amounts paid by the Company under the guarantee based upon their proportionate ownership interests in NTO IRE-Polus.
 
Dr. Valentin P. Gapontsev’s significant ownership interest in this entity creates the possibility of a conflict of interest since, by having an ownership interest in both our company and NTO IRE-Polus, his economic interests may be affected by transactions between the two entities. To address potential or perceived conflicts of interest, we have implemented the following procedures:
 
  •  we have adopted a policy that the Audit Committee of our Board of Directors will review and approve any distributions and dividends to stockholders of NTO IRE-Polus;
 
  •  in accordance with the applicable rules of the Nasdaq Global Market, we conduct an appropriate review of all related party transactions for potential conflict of interest situations on an ongoing basis and all such transactions must be approved by our audit committee;
 
  •  Dr. Valentin P. Gapontsev and Mr. Samartsev granted a proxy to us to vote their shares with respect to NTO IRE-Polus, giving us the ability to vote 90.2% of the total shares of NTO IRE-Polus. We therefore have sufficient votes to elect the general manager of NTO IRE-Polus and approve other changes that require the approval of 662/3% of NTO IRE-Polus’s stockholders; and

Table of Contents

 
  •  Dr. Valentin P. Gapontsev and Mr. Samartsev granted a right of first refusal to us with respect to any sale of their shares of NTO IRE-Polus to existing stockholders of NTO IRE-Polus. Pursuant to the right of first refusal, we may purchase these shares at a price equal to the lesser of the per-share fair value or book value of NTO IRE-Polus as of June 30, 2006. The charter documents of NTO IRE-Polus and applicable Russian law also provide that existing stockholders, including us, have a right of first refusal up to their respective pro rata interests with respect to transfers of shares of NTO IRE-Polus to third parties.
 
Compensation of Dr. Denis Gapontsev
 
Dr. Denis Gapontsev has served as our Vice President, Research and Development since August 2000. Dr. Denis Gapontsev is the son of Dr. Valentin P. Gapontsev, our Chief Executive Officer. The Compensation Committee approves compensation of all executive officers, including that of Dr. Denis Gapontsev. The Nominating and Corporate Governance Committee also has reviewed and approved Dr. Denis Gapontsev’s compensation. Compensation earned in 2007 by Dr. Denis Gapontsev included $240,000 in salary, $72,965 in non-equity incentive plan compensation and $403 in other compensation.
 
Reliant Technologies
 
Mr. Gauthier is a non-employee member of the Board of Directors of Reliant Technologies, Inc., one of our customers. Our total sales in 2007 to Reliant Technologies were $10.3 million.
 
Transactions with International Gull Corporation
 
International Gull Corporation provides consulting services to us, including assistance in opening and managing our operations in India, and acts as a sales representative for us in India. Consulting fees, commissions and health insurance reimbursement amounts paid to International Gull totaled $223,000 in 2007. Verghese Mammen, the owner of International Gull, is the father of Timothy P.V. Mammen, our Chief Financial Officer. Timothy P.V. Mammen has no economic interest in International Gull. Verghese Mammen also serves as a director of our Indian subsidiary, for which he receives no additional compensation.
 
Series B Preferred Stockholders
 
In 2000, we sold 3,800,000 shares of our series B preferred stock and warrants to purchase common stock to a group of investors for a total purchase price of $95.0 million.

Policies and Procedures with Respect to Related Party Transactions
 
The Board adopted a related party transaction policy that requires the Company’s executive officers, directors and nominees for director to promptly notify the Corporate Secretary in writing of any transaction in which (i) the amount exceeds $100,000, (ii) the Company is, was or is proposed to be a participant and (iii) such person or such person’s immediate family members (“Related Persons”) has, had or may have a direct or indirect material interest (a “Related Person Transaction”). Subject to certain exceptions in the policy, Related Person Transactions must be brought to the attention of the Nominating and Corporate Governance Committee for an assessment of whether the transaction or proposed transaction should be permitted to proceed. In deciding whether to approve or ratify the Related Person Transaction, the Nominating and Corporate Governance Committee is required to consider all relevant facts and circumstances, including without limitation the materiality of the Related Person’s direct or indirect interest in the Related Person Transaction, the materiality of the Related Person Transaction to the Company, the impact of the Related Person Transaction on the Related Person, the impact of the Related Person Transaction on the Related Person’s independence (as determined by the Governance Guidelines and the listing standards of the Nasdaq Global Market) and the actual or apparent conflict of interest of the Related Person participating in the Related Person Transaction. If the Nominating and Corporate Governance Committee determines that the Related Person has a direct or indirect material interest in any such transaction, the Committee must review and approve, ratify or disapprove the Related Person Transaction.
 
Pursuant to our Governance Guidelines, we expect each of our directors to ensure that other existing and future commitments do not conflict with or materially interfere with his or her service as a director. Directors are expected to avoid any action, position or interest that conflicts with our interests or gives the appearance of a conflict. In addition, directors should inform the chairman of our Nominating and Corporate Governance Committee prior to joining the Board of another public company to ensure that any potential conflicts, excessive time demands or other issues are carefully considered.

Section 16(a) Beneficial Ownership Reporting Compliance
 
Section 16(a) of the Securities Exchange Act of 1934 requires our directors and executive officers, and persons who beneficially own more than 10% of a registered class of our equity securities, to file reports of ownership of, and transactions in, our securities with the SEC. These directors, executive officers and 10% stockholders are also required to furnish us with copies of all Section 16(a) forms that they file. Based solely on a review of the copies of such forms received by us, and on written representations from certain reporting persons, we believe that during 2007 our directors, executive officers and 10% stockholders complied with all applicable Section 16(a) filing requirements, except Mr. Lopresti filed a Form 4 in September 2007 that contained a clerical error, which was corrected in October 2007 with the filing of an amended Form 4.

Action by the Administrator may include adjustment of: (i) the number and class of Common Stock that may be delivered under the Plan, (ii) the Purchase Price per share, (iii) the number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and (iv) the numerical limits of Section 6.01.
