Executive Compensation Program

The guiding principles of our executive compensation philosophy are pay-for-performance, accountability for annual and long-term performance, alignment with stockholders' interests, and providing competitive pay to attract and retain executives. The 2018 compensation program for our named executive officers has three primary components: annual base salary, annual cash incentives and long-term equity incentives.

Annual Base Salary
Following 2017, a year of 40% revenue growth, salaries were increased to a target percentile of our named peer group reflecting the increased size and complexity of the Company in 2018
We compare our salaries to the peer group selected by the Compensation Committee in consultation with its independent compensation advisor
Annual Cash Incentives
Financial performance fell short of target in 2018, which was reflected in payments that were less than in 2017
Variable cash compensation opportunity is based upon annual net sales and profitability against threshold, target and maximum performance goals
Long-Term Equity Incentives
Align interests of our executives and stockholders by motivating executive officers to increase long-term stockholder value
Service-based equity awards vest over four years providing long-term retention and additional compensation opportunity for increased stock prices
Performance-based stock unit awards provide additional incentives and are earned based on IPG's total stockholder return relative to a broad stock market index
Our CEO, as the founder and a significant stockholder, has not received an equity award since the Company’s public offering in 2006 resulting in lower compensation expenses and equity burn rate for the Company

Alignment with Stockholder Interests and Performance

98%
Say-on-pay approval
during last
stockholder vote
Annual cash incentives are capped and have challenging performance goals linked to key financial performance metrics
Long-term equity incentives are aligned with long-term stockholder value creation
Approximately 79% of non-CEO compensation in 2018 was performance-based
Executives exceed stock ownership guidelines, aligning with interests of stockholders
See “Compensation Discussion and Analysis” beginning on page 30 for a further information on our executive compensation.

Corporate Responsibility

At IPG, corporate responsibility is an important part of our mission. The major areas on which we focus include: (1) innovative and efficient products, (2) environmental stewardship, (3) health, safety and wellness programs for our employees and (4) community participation and contributions. The information below describes several of the key aspects of our corporate responsibility.

Innovative and Efficient ProductsEnvironment
IPG is a leader in fiber lasers. Our fiber lasers have 45-50% wall-plug electrical efficiency, as compared to other types of lasers such as lamp-pumped Nd:YAG and CO2 lasers which have approximately 2% and 7-8% wall-plug efficiencies, respectively.

We estimate that operation of IPG fiber lasers instead of other types of lasers resulted in approximately 28 billion pounds less global CO2 emission since 2011 and 10 billion pounds less CO2 emission in 2018 alone as a result of electricity savings.

To put these savings into perspective, 28 billion pounds of CO2 emission approximates the annual output of six 500 megawatt coal-fired electric plants.


Aside from the positive effect that the adoption of our efficient products provides, we are committed to reducing the environmental impact from our manufacturing and increasing the sustainability of our operations.

Our new construction is built at a level higher than energy codes require. Our new facilities incorporate LED light fixtures, reducing electricity use by 75% compared to incandescent bulbs, and the most water conservative plumbing fixtures available.

We have several co-generation plants that reduce emissions by recycling waste heat from power generation to heat and cool buildings.

IPG operations are compliant with the Restriction of Hazardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE) Directives and the Toxic Substances Control Act (TSCA).

EmployeesCommunities
We provide healthy and safe working conditions to employees and contractors and ensure an inclusive hiring process and work environment. IPG is committed to a culture where all can act with integrity, promote collaboration and deliver results in all that we do.

We have reduced OSHA recordable accidents from 4% in 2010 to 1% in 2018 as a percentage of employees at our Oxford plant.

IPG manufacturing employees undergo comprehensive safety training to help reduce workplace hazards and accidents.

IPG has a long history of caring for our communities around the world, focused on building and supporting collaborative programs to create positive outcomes where we live and work. Our charitable contributions target education, community welfare, civic and social service programs and arts and culture.

Among the many contributions to our communities, IPG sponsors the Society of Women Engineers, promoting the advancement of women in the engineering field.

Also, IPG is a co-founder of the Siegman International School on Lasers, created by the Optical Society of America to expand access to laser education.

QUESTIONS AND ANSWERS
ABOUT THE MEETING AND VOTING
When and Where Is the Annual Meeting? 
When:
  
Thursday, May 30, 2019, at 10:00 a.m. Eastern Time
Where:        
  
IPG Photonics Corporation
50 Old Webster Road
Oxford, Massachusetts 01540
What is the purpose of these materials?
The Board of Directors (the "Board") of IPG Photonics Corporation is soliciting proxies from our stockholders in connection with our annual meeting of stockholders to be held on Thursday, May 30, 2019 and any and all adjournments thereof. This proxy statement and our 2018 annual report are first being made available to stockholders of record on or about April 11, 2019 at investor.ipgphotonics.com. Information on the website does not constitute part of this proxy statement. Unless otherwise noted, the information in this proxy statement covers our 2018 fiscal year, which ran from January 1, 2018 through December 31, 2018.
What Matters Am I Being Asked to Vote On at the Meeting and What Vote is Required to Approve Each Matter?
You are being asked to vote on three proposals.
Proposal 1 requests the election of directors named in this proxy statement. Our bylaws require that, in uncontested elections, each director be elected by the majority of votes cast with respect to such director. This means that the number of shares voted “for” a director nominee must exceed the number of votes cast “against” that nominee in order for that nominee to be elected. Only votes “for” or “against” are counted as votes cast with respect to a director. Abstentions and broker non-votes (as defined below) will have no effect on Proposal 1. To be elected in a “contested election” of directors, which our bylaws define as an election in which the number of nominees for director is greater than the number of directors to be elected, as determined as of the tenth day preceding the date the Company first mails its notice of meeting to stockholders, a director nominee must receive a plurality of the votes cast. The election of directors at the 2019 annual meeting is an uncontested election.
Proposal 2 requests the ratification of the appointment of our independent registered public accounting firm for 2019. The affirmative vote of the holders of a majority of the outstanding shares which are present at the meeting in person or by proxy, and entitled to vote thereon, is required for approval of Proposal 2. Abstentions have the same effect as voting against Proposal 2. Because Proposal 2 is considered a “routine” matter, broker non-votes are not expected to occur with respect to this Proposal.
Proposal 3 requests the approval of the Stock Purchase Plan.  The affirmative vote of a majority of the shares which are present at the meeting in person or by proxy, and entitled to vote thereon, is required for approval of Proposal 3. Abstentions have the same effect as voting against Proposal 3. Broker non-votes will have no effect on Proposal 3.
No business can be conducted at the annual meeting unless a majority of all outstanding shares entitled to vote are either present in person or represented by proxy at the meeting. As far as we know, the only matters to be brought before the annual meeting are those referred to in this proxy statement. If any additional matters are presented at the annual meeting, the persons named as proxies may vote your shares in their discretion.
What happens if a director nominee fails to receive a majority vote in an uncontested election at the 2019 Annual Meeting of Stockholders?
If a nominee who currently is serving as a director does not receive the affirmative vote of at least a majority of the votes cast in an uncontested election, Delaware law provides that the director would continue to serve on the Board as a “holdover director.” However, under our bylaws, each incumbent director is required to submit a letter of resignation as a condition of becoming a nominee of the Board, with the resignation contingent upon not receiving a majority of the votes cast in an uncontested election and acceptance of the resignation by the Board. In such event, the Nominating and Corporate Governance Committee (or another committee designated by the Board) would
7


make a recommendation to the Board as to whether to accept or reject the tendered resignation, or whether other action should be taken. The Board would act on the tendered resignation, taking into account the committee’s recommendation, and would publicly disclose its decision regarding the resignation within 90 days after the results of the election are certified. If the resignation is not accepted, the director would continue to serve until the next annual meeting of stockholders and until the director’s successor is elected and qualified.
Who Is Entitled to Vote at the Meeting?
You are entitled to vote at the meeting if you owned shares of IPG Photonics (directly or in "street name," as defined below) as of the close of business on April 1, 2019, the record date for the meeting. On that date,  53,108,053 shares of our common stock were outstanding and entitled to vote and no shares of our preferred stock were outstanding. Each share of our common stock is entitled to one vote with respect to each matter on which it is entitled to vote. There is no cumulative voting with respect to any proposal.
What Do I Need to Do If I Plan to Attend the Meeting in Person?
If you plan to attend the annual meeting in person, you must provide proof of your ownership of our common stock and a form of personal identification, such as a driver's license, for admission to the meeting. If you are a stockholder of record, the top half of your proxy card is your admission ticket and will serve as proof of ownership. If you hold your shares in street name, a recent brokerage statement or a letter from your bank or broker are examples of proof of ownership. If you hold your shares in street name and you also wish to be able to vote at the meeting, you must obtain a proxy, executed in your favor, from your bank or broker.
What Is the Difference Between Holding Shares Directly as a Stockholder of Record and Holding Shares in "Street Name" at a Bank or Broker?
Most of our stockholders hold their shares directly through a broker, bank or other nominee rather than directly in their own name. As summarized below, there are differences between shares held of record and those held in "street name."
Stockholder of Record: If your shares are registered directly in your name with our transfer agent, Computershare, N.A., you are considered the stockholder of record with respect to those shares, and the proxy statement and annual report were sent directly to you. As the stockholder of record, you have the right to vote your shares as described herein.
"Street Name" Stockholder: If your shares are held by a bank, broker or other nominee on your behalf, you are considered the beneficial owner of shares held in "street name," and the proxy statement and annual report were forwarded to you by your bank, broker or other nominee who is considered the stockholder of record with respect to those shares. Your bank, broker or other nominee sent to you, as the beneficial owner, a document describing the procedure for voting your shares. You should follow the instructions provided by your bank, broker or other nominee to vote your shares. You are also invited to attend the annual meeting. However, if you wish to be able to vote at the meeting, you must obtain a proxy card, executed in your favor, from your bank, broker or other nominee.
What Does it Mean to Give a Proxy?
Your properly completed proxy/voting instruction card will appoint Valentin P. Gapontsev and Angelo P. Lopresti as proxy holders or your representatives to vote your shares in the manner directed therein by you. Dr. Gapontsev is our Chairman of the Board and Chief Executive Officer. Mr. Lopresti is our Senior Vice President, General Counsel and Secretary. Your proxy permits you to direct the proxy holders to vote "For," "Against," or "Abstain" for each of the proposals included in this proxy statement.
All of your shares entitled to vote and represented by a properly completed proxy or voting instruction received prior to the meeting and not revoked will be voted at the meeting in accordance with your instruction.
What Happens If I Sign, Date and Return My Proxy But Do Not Specify How I Want My Shares Voted on One of the Proposals?
Stockholder of Record: Your proxy will be counted as a vote "For" all of the nominees for director (Proposal 1), "For" the ratification of the appointment of our independent registered accounting firm (Proposal 2) and "For" the v approval of the "Stock Purchase Plan" (Proposal 3).
"Street Name" Stockholder: Your bank, broker or nominee may vote your shares only on those proposals on which it has discretion to vote. Under the rules of The Nasdaq Stock Market LLC ("Nasdaq"), your bank, broker or
8


nominee does not have discretion to vote your shares on non-routine matters such as the election of directors (Proposal 1) and approval of the Stock Purchase Plan (Proposal 3). This is called a "broker non-vote." However, your bank, broker or nominee does have discretion to vote your shares on routine matters such as the vote to ratify the appointment of our independent registered public accounting firm (Proposal 2). Accordingly, if you do not give your bank, broker or nominee specific instructions with respect to Proposal 2, your shares will be voted in such entity's discretion (but only with respect to Proposal 2). We urge you to promptly provide your bank, broker or nominee with appropriate voting instructions so that all of your shares may be voted at the meeting.
Can I Change My Vote Before the Meeting?
You can change your vote at any time before your proxy is exercised by delivering a properly executed, later-dated proxy (including an internet or telephone vote), by revoking your proxy by written notice to the Secretary of IPG Photonics, or by voting in person at the meeting. If you choose to revoke your proxy by attending the annual meeting, you must vote your shares for revocation to be effective. The method by which you vote by a proxy will in no way limit your right to vote at the meeting if you decide to attend in person.
If your shares are held in street name, please refer to the information forwarded by your bank, broker or nominee for procedures on changing your voting instructions.
Is the Proxy Statement Available on the Internet?
Yes. We are delivering our proxy statement and 2018 annual report pursuant to the Securities and Exchange Commission rules that allow companies to furnish proxy materials to their stockholders over the Internet. On or about April 11, 2019, we will mail to our stockholders a notice (the “Notice”) containing instruction on how to access this proxy statement and our annual report and to vote via the Internet or by telephone. Stockholders can view these documents on the Internet by accessing the website at investor.ipgphotonics.com.
What does it mean if I receive more than one Notice of Internet Availability of Proxy Materials?
You may receive more than one Notice, more than one e-mail or multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you may receive a separate Notice, a separate e-mail or a separate voting instruction card for each brokerage account in which you hold shares. If you are a stockholder of record and your shares are registered in more than one name, you may receive more than one Notice, more than one e-mail or more than one proxy card.
To vote all of your shares by proxy, you must complete, sign, date and return each proxy card and voting instruction card that you receive and vote over the Internet the shares represented by each Notice that you receive (unless you have requested and received a proxy card or voting instruction card for the shares represented by one or more of those Notices).
Who Is Soliciting my Proxy and Who is Paying for the Cost of this Proxy Solicitation?
The Board of IPG Photonics is soliciting your proxy to vote at the 2019 annual meeting of stockholders. IPG Photonics will bear the expense of preparing, posting to the Internet, printing and mailing this proxy material, as well as the cost of any required solicitation. Our directors, officers or employees may solicit proxies on our behalf. We have not engaged a proxy solicitation firm to assist us in the solicitation of proxies, but we may if we deem it appropriate. In addition, we will reimburse banks, brokers and other custodians, nominees and fiduciaries for reasonable expenses incurred in forwarding proxy materials to beneficial owners of our stock and obtaining their proxies.
Who Counts the Votes?
We have engaged Computershare, N.A. as our independent agent to receive and tabulate stockholder votes. Computershare, N.A. will separately tabulate "For" and "Against" votes, abstentions and broker non-votes. Computershare, N.A. will also act as independent election inspector to certify the results, determine the existence of a quorum and the validity of proxies and ballots, and perform any other acts required under the General Corporation Law of Delaware.

9


How Can I Vote?
Most stockholders have a choice of voting in one of four ways:
via the Internet,
using a toll-free telephone number,
completing a proxy/voting instruction card and mailing it in the postage-paid envelope provided or
in person at the meeting.
The telephone and internet voting facilities for stockholders of record will close at 1:00 a.m. Central Time on May 30, 2019. The internet and telephone voting procedures are designed to authenticate stockholders by use of a control number and to allow you to confirm that your instructions have been properly recorded.
If you hold your shares in "street name," your bank, broker or other nominee will send you a separate package describing the procedures and options for voting your shares. Please read this information carefully. If you hold your shares in "street name," and wish to vote in person at the annual meeting, you must obtain a "legal proxy" from the organization that holds your shares. A legal proxy is a written document that will authorize you to vote your shares held in "street name" at the annual meeting. Please contact the organization that holds your shares for instructions regarding obtaining a legal proxy. You must bring a copy of the legal proxy to the annual meeting and ask for a ballot when you arrive.

What Is the Quorum Required to Transact Business?
At the close of business on April 1, 2019, the record date, there were 53,108,053 shares of our common stock 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 broker non-votes and proxies marked "abstain" as present in determining whether a quorum exists.

CORPORATE GOVERNANCE
Significant Governance Highlights
At IPG Photonics, we believe that strong and effective corporate governance procedures and practices are an extremely important part of our corporate culture. The following summarizes the structure of our Board and key elements of our corporate governance framework:

Director Independence
Tenure of Independent DirectorsAverage Age of Independent Directors
Seven of ten directors are independent

The Board has delegated responsibility for oversight of specific risks to Board committees
 
The Board recently approved enhancements to our corporate governance: 
Proxy Access. In 2019, we adopted proxy access bylaw amendments.  Proxy access refers to the right of a long-term stockholder to nominate alternative board candidates on the Company’s proxy card for the Company’s annual meeting of stockholders and utilize the Company’s proxy statement to solicit votes for the stockholder’s nominees.
Majority Voting for Uncontested Elections. In 2018, we adopted majority voting provisions to our bylaws that provide for election of directors under a majority voting standard with a director resignation policy for failure to receive a majority vote in an uncontested election of directors. 
Additional information is provided below regarding these and certain other key corporate governance policies, which we believe enable us to manage our business in accordance with high standards of business practices and in the best interest of our stockholders.  
11


Corporate Governance Guidelines
Our Board has adopted Corporate Governance Guidelines that outline, among other matters, the roles and functions of the Board, the responsibilities of various Board committees and the mission of the Board. Each of the Board committees has a written charter that sets forth the purposes, goals and responsibilities of the committees as well as qualification for committee membership, procedures for committee membership, appointment and removal, committee structure and operations and committee reporting to the entire Board.
The Corporate Governance Guidelines provide, among other things, that:
a majority of our Board must be independent,
the Presiding Independent Director presides over executive sessions of independent directors,
the Board appoints all members and chairpersons 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 or on more than two other audit committees of public companies,
evaluation of the Board is conducted annually, and
the Board and key officers should have a meaningful financial stake in the Company.
The Board reviews changing legal and regulatory requirements, evolving best practices and other developments. The Board modifies the Corporate Governance Guidelines and its other corporate governance policies and practices from time to time, as appropriate. Several of our policies, including or Corporate Governance Guidelines and committee charters, may be found at investor.ipgphotonics.com/governance/governance-documents. Note that information on our website does not constitute part of this proxy statement.
Executive Sessions. Our independent directors meet privately, without employee directors or 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 of the independent directors are held as often as deemed necessary by them. The Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee meet without employee directors or management present from time to time as they deem necessary.
Director Meetings and Policy Regarding Board Attendance. It has been the practice of our Board and its committees to hold at least four in-person regular meetings each year. The Board and its committees also have telephone meetings throughout the year. See "Standing Committees and Board Membership" below for additional information regarding meetings held in 2018. In accordance with our Corporate Governance Guidelines, our directors are expected to prepare for, attend and actively participate in meetings of the Board and its committees. 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. In 2018, three of the directors in office attended the annual meeting of stockholders.
Stock Ownership Guidelines. The Board adopted stock ownership guidelines to more closely align the interests of our directors and executive officers with those of our long-term stockholders. Under the guidelines, the following persons are expected to maintain a minimum investment in our common stock as follows: for non-employee directors, the lesser of 3,000 shares or three times their annual cash Board retainer (excluding committee retainers); for the Chief Executive Officer, five times his annual salary; and for senior executive officers, the lesser of 5,000 shares or one times their respective annual salaries. Vested stock options and unvested restricted stock units count toward the stock ownership levels. Indirect ownership of shares through a separate legal entity counts toward fulfillment of the ownership guidelines. These ownership levels are to be achieved no later than four years after the election as a director or as an executive officer, except that prior to such time the director or officer is expected to retain a certain portion of stock issued upon exercise of stock options or vesting of restricted stock units until the minimum ownership levels are attained. All directors and executive officers were in compliance with our stock ownership guidelines as of December 31, 2018.



12


Board Self-Assessments. The Board conducts annual self-evaluations and its committees conduct bi-annual self-assessments to determine whether they are functioning effectively. The Nominating and Corporate Governance Committee oversees the Board and committee self-assessments. Each committee also reviews its own performance bi-annually and reports the results to the Board. Each committee reviews and reassesses the adequacy of its charter annually and recommends proposed changes to the Board.
Prohibition on Hedging; Limits on Pledging. Under our insider trading policy, no director or employee may engage in shorting shares of our common stock, or buying or selling puts, calls or derivatives related to our common stock or other Company securities, which includes equity compensation. A director or officer of the Company may not pledge shares constituting more than 20% of his or her total stock ownership. Pledges of shares constituting 20% or less of total stock ownership are subject to certain conditions.

Governance Trends and Director Education.  The Board and its committees proactively monitor legislative and regulatory initiatives, as well as other corporate governance trends and their potential impact on the Company. Each director has access to publications and other resources that cover these matters. In addition, we reimburse relevant director education expenses.
The Board receives presentations from professionals with expertise in corporate law, governance and other related topics. These experts have specialized knowledge of regulatory actions, governance trends and various other corporate governance topics. Additionally, our directors participate in continuing education sessions to remain informed on recent trends applicable to their committee duties.
Likewise, newly elected directors attend a comprehensive director orientation program that covers, among other things, our strategy, business structure, financial performance, and competitive landscape. New committee members are also provided training on committee policies, practices and trends. As part of this program, directors are invited to participate in a tour of selected facilities of the Company. To further familiarize directors with our expanding operations, we conduct Board meetings at our major facilities from time to time.

Code of Business Conduct. We have 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 investor.ipgphotonics.com/governance/governance-documents.
Procedures for Submitting Complaints. We have procedures to treat complaints regarding accounting, internal accounting controls, auditing matters, fight against bribery, banking, and financial crime, including submission of confidential and anonymous concerns regarding questionable accounting, internal accounting controls or auditing matters raised by our directors, officers and employees. These procedures are posted on our website at investor.ipgphotonics.com/governance/governance-documents.

1.The Board has determined that each member of the Audit Committee is financially literate. The Board has designated Ms. Lego and Mr. Seifert, who are each independent directors under the Nasdaq listing standings and the SECs audit committee requirements, as “audit committee financial experts” pursuant to the SEC’s final rules implementing Section 407 of the Sarbanes-Oxley Act. Stockholders should understand that the designation of Ms. Lego and Mr. Seifert each as an “audit committee financial expert” is an SEC disclosure requirement and that it does not impose upon them any duties, obligations, or liabilities that are greater than those imposed on them as members of the Audit Committee and the Board in the absence of such designation.
2.The Board has determined that each member of the Audit and Compensation Committees meets the independence standards specific to members of such committees under Nasdaq guidelines and SEC rules.

Copies of the charters of each of the three committees can be found on our website at investor.ipgphotonics.com/governance/governance-documents.
The table below sets forth the number of meetings held by each committee and the full Board in 2018. All incumbent directors attended 75% or more of the aggregate meetings of the Board and committees on which they served during 2018. We encourage directors to attend the annual meeting of stockholders, but we do not have a formal policy regarding such attendance. Last year, three of the directors in office attended the annual meeting.

Nomination of Directors 
Director Selection Guidelines. The Nominating and Corporate Governance Committee has approved guidelines for selecting directors. Criteria considered in the selection of directors include:
the extent that the director/potential director has demonstrated excellence, leadership and significant experience in a field of endeavor;
whether the director/potential director assists in achieving a collective membership on the Board with a broad spectrum of experience and expertise;  
diverse professional experience, substantive expertise, skills and background, as well as diversity in personal characteristics, such as age, ethnicity, gender and race;  
whether the director/potential director can read and understand financial statement fundamentals and is committed to representing the long-term interests of the Company’s stockholders, while keeping in perspective the interests of the Company’s customers, employees and the public;  
the needs of the Company at the time of nomination to the Board and the fit of a particular individual’s skills and personality with those of the other directors in building a Board that is effective and responsive to the needs of the Company; and  
whether the director/potential director meets the independence requirements of the listing standards of the Nasdaq and SEC rules (where independence is desired).
No potential director (excluding any incumbent director) with an age less than 21 years or greater than 72 years is eligible for election as a Board member. Each director/potential director must comply with the limits on other board memberships in our Corporate Governance Guidelines.
The Nominating and Corporate Governance Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. The Nominating and Corporate Governance Committee seeks a Board that reflects diversity, in experience, age, ethnicity, national origin, gender and race, although it does not have formal objective criteria for determining the degree of diversity desired on the Board.
In the last few years, the Board has taken an active approach to refreshing its members in order to increase the effectiveness of the Board, including by increasing its focus on Board diversity. For example, the Board has added a female director and two directors born in Europe with significant international business experience. In 2019, we added a director with experience in photonics and optical components businesses. Of these newer directors, two were under 60 years old when they joined our Board. We typically seek candidates with experience on public company boards as such candidates understand the role and duties of directors and individually who add different sets of experience and skills that are important to the Company. Based on this criterion, we have added directors with photonics, electronics and semiconductor equipment industry backgrounds, larger company and
15


entrepreneurial experience, European and Asia experience, as well as experience in positions associated with accounting, finance and information technology, all of which contribute to the quality of the review and oversight by the Board, Board-management discussions and IPG's long-term strategy.
Director Nomination Process. The Nominating and Corporate Governance Committee identifies potential director nominees through contacts of the Board, executives and a variety of other sources. The committee has retained and may in the future retain a search firm or utilize third-party database search tools to identify director nominees.
The Nominating and Corporate Governance Committee considers several factors prior to nominating a candidate. Generally, the committee considers the existing size, future requirements of the Board, composition skills and diversity of the Board, evaluates biographical information and other background material and interviews each candidate selected. The Nominating and Corporate Governance Committee applies director selection criteria adopted by it based on the circumstances at the time and the criteria set forth in our Corporate Governance Guidelines.
The Nominating and Corporate Governance Committee considers all director candidates identified through the processes described above and evaluates each of them, including incumbents, based on the same criteria. If based on the committee’s initial evaluation, a director candidate continues to be of interest to the Nominating and Corporate Governance Committee, the chair of such committee and other committee members will interview the candidate and communicate the evaluation to the committee and executive management. Additional interviews are conducted and all members of the Board may interview the final candidates. Ultimately, the Nominating and Corporate Governance Committee will meet to finalize its list of recommended candidates for the Board’s consideration.
The Nominating and Corporate Governance Committee also considers candidates for nomination as a director submitted by stockholders. The Nominating and Corporate Governance Committee’s evaluation process and criteria does not vary based upon whether a candidate is recommended by a stockholder. However, the procedural requirements set forth in our bylaws and the procedures described under "Other Matters - 2020 Annual Meeting and Nominations" must be met.
Proxy Access Bylaw. In 2019, we adopted a proxy access provision in our bylaws. It permits a stockholder, or group of up to 20 eligible stockholders, that has maintained continuous ownership of three percent or more of our common stock continuously for at least three years to include in our proxy materials for an annual meeting of stockholders a number of director nominees constituting up to the greater of two director nominees or 20 percent of the number of directors up for election as of the last day on which a notice of proxy access nomination may be delivered to the Company.
The proponent is required to provide the information about itself and the proposed nominee(s) that is specified in the proxy access provision of our bylaws. The required information must be in writing and provided to the Secretary of the Company not less than 120 days nor more than 150 days prior to the anniversary of the date that the Company first distributed its proxy statement to stockholders for the immediately preceding annual meeting of stockholders. We are not required to include any proxy access nominee in our proxy statement if the nomination does not comply with the proxy access requirements of our bylaws. Any stockholder considering utilizing proxy access should refer to the specific requirements set forth in our bylaws.
Board Leadership Structure
As of the date of this proxy statement, the positions of Chairman of the Board and Presiding Independent Director are held by two different individuals. Dr. Gapontsev, our Chief Executive Officer, also serves as the Chairman of the Board. Our independent directors determined several years ago that, for effective Board governance, it is important to have a presiding independent director. Mr. Peeler has been selected as the Presiding Independent Director for the term ending May 2019.
Dr. Gapontsev became our Chief Executive Officer and Chairman in 1998. His dual role was created when the Board was first established in 2000. Our directors believe that each of the possible leadership structures for a board has its particular benefits and drawbacks which must be considered in the context of the specific circumstances, culture and challenges facing a company, and that such consideration is the responsibility of a company's board that has a diversity of views and experiences. Our directors come from a variety of organizational backgrounds and have direct experience with a wide range of leadership and management structures. The makeup of our Board puts it in a strong position to evaluate the pros and cons of the various types of board leadership structures and to ultimately decide which form is in the best interests of our stockholders. The independent directors believe that having
16


Dr. Gapontsev serve in both capacities is in the best interest of the Company and its stockholders because it allows Dr. Gapontsev to more effectively execute the Company's strategic initiatives and business plans. He is the founder of the Company and beneficially owns approximately 14% of the Company's common stock. The duality of Dr. Gapontsev's roles as Chairman and Chief Executive Officer creates clear and unambiguous authority, which is essential to effective management. The Board and management can respond more effectively to a distinct line of authority. Further, given that he is closer to the Company's business than any other Board member and he has the benefit of over twenty-five years of operations, technology, strategy and executive management experience within the Company, Dr. Gapontsev is best-positioned to set the Board's agenda and provide leadership. Dr. Gapontsev's extensive scientific and business experience also gives him vast industry knowledge, which the Board believes is critical for the chairman of the board of a company that operates in a highly technical industry. The combined Chairman/Chief Executive structure is a leadership model that has served our stockholders well for many years.
The Board also recognizes the importance of having in place, and building upon, a counterbalancing structure to ensure that it functions in an appropriately independent manner. As a result, the Board enhanced its governance structure several years ago by creating the position of Presiding Independent Director with leadership authority and responsibilities. The duties and responsibilities of the Presiding Independent Director include: setting the agenda for  and leading executive sessions of the independent directors; providing consolidated feedback from those meetings to the Chairman and Chief Executive Officer; providing input on the agenda for Board meetings; periodically providing feedback on the quality and quantity of information flow from management; having the authority to call meetings of the independent directors; facilitating discussions outside of scheduled Board meetings among the independent directors on key issues as required; serving as a non-exclusive liaison with the Chairman and Chief Executive Officer in consultation with the other independent directors; interviewing Board candidates as appropriate; and leading the determination of the goals and objectives for the Chairman and Chief Executive Officer with the input of the independent directors and the annual performance evaluation for him with the input of the independent directors. In the event of a crisis, the Presiding Independent Director would have an increased role in crisis management oversight. The independent directors of our Board elected Mr. Peeler as the Presiding Independent Director for the term ending May 2019, and this position is voted upon annually by our independent directors.
The independent directors as a group determine the CEO’s base salary and opportunities for annual and long-term compensation based upon recommendations of the Compensation Committee. Each year, the independent directors also determine the annual goals and objectives for the CEO, assess the CEO’s attainment of them and decide the CEO’s individual performance award under the Company’s annual incentive plan.  
The Board believes that the position and responsibilities of the Presiding Independent Director and the regular use of executive sessions of the independent directors without the CEO or other executive officers present, along with the Company's strong committee system and substantial majority of independent directors, allow the Board to maintain effective oversight.
Risk Oversight
The Board and management recognize that effectively monitoring and managing risk are essential to the successful execution of the Company's strategy. The Board reviews strategy regularly with management and provides input to management. As part of its oversight of operations, the entire Board reviews and discusses the performance of the Company and the principal risks involved in the operations and management of the Company. The Board allocates risk oversight responsibility among the full Board, the independent directors acting as a group and the three standing committees of the Board. The Nominating and Corporate Governance Committee periodically reviews risk oversight matters and responsibilities, then makes recommendations to the Board to allocate risk oversight responsibilities.
The Board as a whole reviews risk management practices and a number of significant risks in the course of its reviews of corporate strategy, management reports and other presentations. The independent directors as a group, the Audit Committee and the Compensation Committee all participate in senior executive succession and resource planning. The standing committees also contribute to succession and resource planning oversight for management. The Audit Committee oversees certain financial risks and recommends guidelines to monitor and control such exposures. The Compensation Committee reviews the Company's executive compensation programs, their effectiveness at both linking executive pay to performance and aligning the interests of our executives and our stockholders, and oversees an entity-wide compensation risk assessment. The Nominating and Corporate Governance Committee reviews significant related person transactions with directors, executives and managers and may conduct negotiations on behalf of the Company in connection with related person transactions and retain independent advisors to assist it. The Board's risk oversight role is independent from the Company's day-to-day
17


management, as more than two-thirds of the current directors are independent and therefore have no conflicts that might discourage critical review of the Company's risks.
Communication with our Board of Directors
Interested parties wishing to write to the Board, a specified director or a committee of the Board should send correspondence to the Office of the Secretary, IPG Photonics Corporation, 50 Old Webster Road, Oxford, Massachusetts 01540. All written communications received in such manner from stockholders of the Company will 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(s) of the Board, the communication shall be forwarded to all members of the Board.

18


RELATED PERSON TRANSACTIONS
The Board adopted a related person transaction policy that requires the Company's executive officers, directors, nominees for director and owners of more than 5% of the Company's shares to promptly notify the 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. In deciding whether to approve or ratify the Related Person Transaction, the Nominating and Corporate Governance Committee considers relevant facts and circumstances. If the Nominating and Corporate Governance Committee determines that a 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 Corporate 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 are required to 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.
The Nominating and Corporate Governance Committee reviewed and approved the following Related Person Transactions which were conducted on an "arm's length" basis with the Company. Members of the Nominating and Corporate Governance Committee having an interest in a transaction excuse themselves for the consideration and approval of the transaction in which they have an interest.
In 2018, the Company purchased from Veeco Instruments Inc. various equipment, parts and services amounting to approximately $947,325 Mr. Peeler, a non-employee member of our Board, is the Executive Chairman of Veeco Instruments Inc. For several years before Mr. Peeler was elected to our Board, Veeco Instruments Inc. was a provider of equipment, parts and services to the Company.
Dr. Gapontsev leases the annual right to use 25% of the Company's corporate aircraft under an October 2014 lease (the "2014 Lease"), which was superseded by a new lease signed in July 2017 (the "2017 Lease") in connection with the purchase of a different aircraft. The 2017 Lease expires in July 2022. The annual lease rate under the 2017 Lease is $924,700 and future rent payments are adjusted annually. Dr. Gapontsev paid the Company $924,721 in 2018 for use of the aircraft, and in addition directly paid an unrelated flight management firm for the operating costs of his private use, including pilot fees, fuel and other costs.

Director Independence
Seven of our ten current directors are independent as defined by Nasdaq and SEC rules. A predominantly independent Board ensures that the Board is acting objectively and in the best interests of our stockholders. The independent directors also bring expertise and a diversity of perspectives to the Board. The culture of the Board enables directors to openly express their opinions in the boardroom and to raise challenges. The Nasdaq listing standards governing independence require that a majority of the members of the Board be independent as defined by Nasdaq. The Board conducted its annual review of director independence in March 2019. During this review, the Board examined all direct and indirect transactions or relationships between the Company or any of its subsidiaries and each current director and any immediate family member of the director and determined that no material relationships with the Company existed during 2018. On the basis of this review, the Board determined that each of the following directors qualifies as an independent director as defined in the Nasdaq guidelines and SEC rules: Michael C. Child, Gregory P. Dougherty, Henry E. Gauthier, Catherine P. Lego, Eric Meurice, John R. Peeler and Thomas J. Seifert.  The Board had previously determined that Mr. William Hurley, who served on the Board during 2018, was independent. Additionally, the Board has determined that each member of the Audit Committee and the Compensation Committee meets the independence standards specific for members of such committees under Nasdaq guidelines and SEC rules.

Compensation Committee Interlocks and Insider Participation
No member of our Compensation Committee (Ms. Lego and Messrs. Dougherty, Meurice and Peeler) is or has been an officer or employee of our Company or any of our subsidiaries. None of our executive officers served as a member of:
the compensation committee of another entity in which one of the executive officers of such entity served on our Compensation Committee; 
the compensation committee of another entity in which one of the executive officers of such entity served as a member of our Board; or
the board of directors of another entity, one of whose executive officers served on our Compensation Committee. 

Director Tenure 
Since 2012, IPG has undertaken a significant “refresh” of its independent directors. Now, over 70% of our independent directors have seven years or less of service with IPG:
chart-49c91e74a5014c3abfc.jpg
As of June 2019
The average tenure of our independent directors is seven years and the average age of our independent directors is 62 years. Fourteen percent of our independent directors represent gender diversity.
In determining whether to recommend a director for re-election, the Nominating and Corporate Governance Committee considers the director’s skills and expertise, participation in and contributions to the activities of the Board.
We believe that the tenure spectrum of our directors provides an effective mix of deep knowledge and new perspectives. The Board does not believe in a specific limit for the overall length of time an independent director may serve. Directors who have served on the Board for an extended period can provide valuable insight into the operations and future of the Company based on their experience with, and understanding of, the Company’s culture, history and objectives. Our Corporate Governance Guidelines provide that a director is expected to retire at the conclusion of the Board meeting immediately prior to a director’s 72nd birthday. The Board considered the
25


valuable continuing contribution of Mr. Gauthier and determined that he should remain on the Board in 2019. Mr. Gauthier, the former CEO of a large publicly-held laser developer and manufacturer, and Mr. Child, a former partner of a private equity fund, both have longer service on the Board. We see a strategic advantage from their senior-in-service status. Not only do they bring industry, acquisition and financial experiences, deep institutional knowledge, and historical context to the vitality and growth of IPG, they serve as seasoned and trusted advisors to Dr. Gapontsev and our executives.
Different tenures coupled with an independent and objective Board have served our stockholders well for many years.

PROPOSAL 1: ELECTION OF DIRECTORS
The Nominating and Corporate Governance Committee is responsible for identifying and evaluating nominees for director and for recommending to the Board a slate of nominees for election at the Annual Meeting. The Nominating and Corporate Governance Committee has recommended, and the Board has approved, the persons named as nominees for terms expiring in 2020 and, unless otherwise marked, a proxy will be voted for such nominees.
The stockholders are being asked to elect Dr. Gapontsev, Dr. Scherbakov, Mr. Samartsev, Mr. Child,  Mr. Dougherty, Mr. Gauthier, Ms. Lego, Mr. Meurice, Mr. Peeler and Mr. Seifert to terms ending with the annual meeting to be held in 2020, until a successor is elected and qualified or until his or her earlier death, resignation or removal.  All of the director nominees set forth in our proxy card have consented to being named in this proxy statement and to serving if elected. For more information regarding the nominees for director, see "Board of Directors."
In considering each director nominee and the composition of the Board as a whole, the Nominating and Corporate Governance Committee considers a diverse group of experiences, qualifications, attributes and skills, including diversity in age, gender, national origin, ethnicity and race, which the Nominating and Corporate Governance Committee believes enables a director nominee to make significant contributions to the Board, IPG and our stockholders.
The current-serving directors, including the nominees, collectively have a mix of various skills and qualifications, some of which are listed in the table below. These collective attributes enable the Board to provide insightful leadership as it strives to advance our strategies and deliver returns to stockholders.

COMPENSATION DISCUSSION AND ANALYSIS
This Compensation Discussion and Analysis provides a review of our executive compensation philosophy and program, and Compensation Committee decisions for fiscal 2018. The discussion in this section focuses on the compensation of the "Named Executive Officers" or "NEOs" for fiscal 2018, who were:
Valentin P. Gapontsev, Ph.D., our Chairman and Chief Executive Officer
Eugene Scherbakov, Ph.D., our Chief Operating Officer, the Managing Director of IPG Laser GmbH, our subsidiary, and Senior Vice President, Europe
Timothy P.V. Mammen, our Senior Vice President and Chief Financial Officer
Angelo P. Lopresti, our Senior Vice President, General Counsel and Secretary
Alexander Ovtchinnikov, Ph.D., our Senior Vice President, Components
Summary of Executive Compensation Pay Practices
The guiding principles of our executive compensation philosophy and practice continue to be pay-for-performance, accountability for annual and long-term performance, alignment to stockholders' interests, and providing competitive pay to attract and retain executives. We believe our compensation program strikes the appropriate balance between utilizing responsible, measured pay practices and effectively incentivizing our executives to dedicate themselves fully to value creation for our stockholders.
Executive Compensation Design
Our executive compensation program is designed to focus executive officers on both annual and long-term financial and operational performance, without encouraging unnecessary risk. The following graphs show approximately 36 percent of the CEO's total direct compensation and approximately 79 percent of the average total direct compensation of all of the other NEOs' compensation, as reflected in the 2018 column of the Summary Compensation Table, is at risk.
Our CEO, the Company's founder, does not receive long-term incentives because of his significant level of common stock ownership, which the independent directors believe provides him sufficient incentives to act in the best long-term interest of our stockholders. As a result, a smaller percentage of his total compensation is performance-based as compared to the chief executives of our peer companies who typically receive additional compensation in the form of substantial long-term incentives.

Other NEOs

The following provides details on the components of our executive compensation program:
Compensation ElementObjective
Base Salary  •Provide a competitive fixed component of cash compensation to attract and retain talented and experienced executives with the knowledge and skills necessary to achieve the Company's strategic business objectives.
  •The Compensation Committee uses the services of an independent compensation consultant to assess the base salaries as compared to a competitive target range of the Company's peer group.
  •The Compensation Committee considers these factors when setting base salaries of the executive officers: scope of the executive's responsibilities, contributions, skills, knowledge, experience, seniority and annual and long-term Company performance.
Annual Incentive Plan
  •Offer a variable cash compensation opportunity earned based upon the level of achievement of challenging corporate goals, with additional compensation opportunity based upon individual performance.
  •
Foster a shared commitment among executives through establishment of uniform Company financial goals.

  •
Award payouts are subject to a cap of 225% of target in a performance period.

Long-Term
Incentives
  •Align interests of our executives and stockholders by motivating executive officers to increase long-term stockholder value.
  •Service-based equity awards include stock options and restricted stock units. They offer certainty and long-term retention while providing additional compensation opportunity based upon increased stock price levels. Stock options further align executives with the long-term growth of stockholder value.
  •Performance-based stock units provide additional incentive to our NEOs (other than the CEO) and are earned based on IPG's total stockholder return relative to a broad stock market index.
  •Enhance retention with vesting over four years.
401(k) Retirement Savings Plan
  •Provides participants the opportunity to defer a portion of their compensation and receive a company match of 50% of deferrals subject to a maximum of 6% of eligible compensation.
  •The plan is available to all eligible U.S. employees.
Pension PlanWe provide no pension plan or deferred compensation plan.
PerquisitesPerquisites are limited.

Say-On-Pay
At our 2017 annual meeting of stockholders, our stockholders overwhelmingly approved our executive compensation structure in a "say-on-pay" advisory vote, voting 98% percent in favor of our executive compensation structure. At our stockholders meeting in 2017, the advisory proposal to hold "say-on-pay" advisory votes every three years received the greatest amount of votes and, therefore, we elected to submit the advisory "say-on-pay" proposal to our stockholders on a triennial basis. Accordingly, the next "say on pay" advisory vote is being held at our annual meeting of stockholders to be held in 2020.
2018 Base Salaries
We provide base salary to our NEOs 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 performance risk. The Compensation Committee reviews information provided by its compensation consultant and considers the experience, skills, seniority, knowledge and responsibilities of the executive and the individual's performance assessment provided by the CEO to assist it in evaluating base salary for each NEO. With respect to the CEO, the Compensation Committee additionally considers the performance of the Company as a whole in its recommendation to the independent directors, who set CEO compensation.
In 2018, the Compensation Committee evaluated the base salaries and total cash compensation for the NEOs with the assistance of Radford. The Compensation Committee reviewed Radford's assessment in connection with positioning the midpoint of the Company's target total cash compensation range near the 65th percentile of our peer group. Following 2017, a year of 40% revenue growth, salaries were increased in 2018, reflecting the larger size and complexity of the Company in 2018. Dr. Gapontsev received an increase in base salary of 12% bringing his base salary in line with the market 65th percentile of our peer group, which also factored in the fact that the Compensation Committee does not grant any equity awards to Dr. Gapontsev. Likewise, the salary of Dr.
31


Scherbakov increased approximately 26% to 550,900 (which was then equivalent to $679,400), which also factored in his additional management responsibilities related to his appointment as Chief Operating Officer in February 2018. Finally, the Compensation Committee approved merit increases of 5% for the base salaries of Messrs. Mammen, Ovtchinnikov and Lopresti.
2019 Update. In light of challenging macroeconomic conditions continuing into 2019, the independent directors accepted the Compensation Committee’s recommendation to not increase the base salary of the CEO and the Compensation Committee concurred with the CEO's recommendation to not increase the base salaries of the other NEOs in 2019.
2018 Cash Incentive Awards
To focus each executive on the importance of the Company's performance, a significant portion of the individual's potential short-term compensation is in the form of annual cash incentive pay that is tied to the achievement of goals set by the Compensation Committee. Our NEOs participate in our Senior Executive Annual Incentive Plan (the "AIP") administered by the Compensation Committee. The Compensation Committee determines who is eligible to receive awards under the AIP, defines performance goals and objectives for executives, establishes target awards for each participant for the relevant performance period, and determines the percentage of the target award that should be allocated to the achievement of each of the chosen performance goals in consultation with the CEO with respect to other executives. The target award percentages established by the Compensation Committee are chosen with input from the compensation assessment conducted by Radford and the seniority level of the executive.
Consistent with prior years, in 2018 the Compensation Committee identified two financial performance measures: net sales and adjusted EBIT and assigned a 50% weighting factor to each financial performance goal. Non-GAAP "Adjusted EBIT" is an internally defined performance measure that is derived from GAAP net income by adding back the provision for income taxes, interest expense and stock-based compensation expenses and deducting interest income. Adjusted EBIT excludes stock-based compensation expenses as they can vary substantially from period to period due to changes in the stock price, compensation practice and structure as well as the number of equity grants in the year, which are variables that are not under the control of the executives. We believe the use of non-GAAP Adjusted EBIT is a useful measure allowing the Compensation Committee to compare and reward operational performance on a more consistent basis without significant variations arising from income taxes, interest income or expense and stock-based compensation. The Compensation Committee intentionally focused on net sales growth and pretax profits so that our executives would be incentivized to deliver the types of growth that benefit our stockholders, namely increasing sales and profits.
Under the 2018 AIP, the NEOs could receive cash incentive payments in the table below as a percentage of base salaries based upon achievement of the minimum to maximum objectives for both financial performance measures and individual performance. If the financial performance exceeds one or more of the stretch objectives the incentive payments to the NEOs would be limited at 200% of the financial performance target payout. If both minimum financial objectives established by the Compensation Committee in 2018 are not met, the Compensation Committee has the discretion to grant an award for individual performance. The Compensation Committee also has the discretion to reduce the payments for attainment of revenue targets and individual performance measures if the Company incurs earnings losses. The individual goals and objectives for the CEO include operational and strategic targets determined by the independent directors.
The overall target awards in the table below are a percentage of the respective base salaries. The company-wide financial objectives are the same for all executive officers in order to foster a shared commitment among them.

While financial performance targets were intended to be achievable by the Company, a maximum bonus would require very high levels of Company performance. The Compensation Committee excluded the acquisition of
32


Genesis Systems Group, LLC and other acquisitions occurring in 2018 and significant unbudgeted legal expenses from the calculation of the 2018 bonus. The target levels for net sales and Adjusted EBIT were $1,619 million and $649 million, respectively, representing 15% and 9% increases, respectively, from prior year levels. The Compensation Committee's adjusted minimum and stretch targets for net sales were $1,409 million and $1,832 million, and for Adjusted EBIT were $521 million and $733 million.
After adjustments, the Company achieved net sales of $1,449 million and Adjusted EBIT of $550 million. These results represented a 3% increase in net sales and a 9% decrease in Adjusted EBIT from 2017 levels.  Following the high growth of 2017, the Company faced a challenging macroeconomic environment in 2018, affecting our two largest regions, Europe and China, exacerbated by the U.S.-China trade conflict, escalating tariffs and increased customer uncertainty. During the year, the Company continued to invest in future development and infrastructure which, together with the impact of increased price competition, lowered margins and earnings. Both net sales and Adjusted EBIT were below target levels but above threshold levels set by the Compensation Committee.  The independent directors set the individual goals and objectives for the CEO in 2018 and reviewed the CEO's attainment of the goals. As a result of this process, the independent directors awarded the CEO 27.5% of his base salary for his individual performance during 2018. The Compensation Committee, with input from the CEO, awarded the Chief Operating Officer 25.0% of his base salary and the other NEOs 20% of their respective base salaries for their individual performances in 2018.
The Compensation Committee may award discretionary bonuses to executives for exceptional performance. For 2018, the Compensation Committee did not exercise this right.
2019 Update. In February 2019, the Committee approved annual financial targets and incentive payouts to the NEOs for the fiscal year 2019 AIP. The financial performance targets have changed for the 2019 AIP, but the incentive payout targets as a percentage of salary have not changed from the 2018 AIP.

 Equity-Based Incentives Granted in 2018
 The goal of our equity-based award program is to provide employees and executives with the perspective of an owner with a long-term financial stake in our success, further increasing alignment with stockholders. Our equity-based incentives align the interests of our executives and stockholders by motivating executives to increase long-term stockholder value.
In 2018, our equity-based award program for executives included service-based stock options (33%), service-based restricted stock units (33%), and performance-based stock units (at target, 33%). The type and proportion of the equity grants reflected a 2018 review by our Compensation Committee with the assistance of Radford of grant practices at peer companies. The value of stock options, restricted stock units and performance-based stock units are tied to the Company stock price which links pay to performance.
Consistent with our pay-for-performance philosophy, the service-based stock option awards have no value unless our stock price increases after the grant date. Another reason why we use service-based stock options is because it fosters an innovative environment focused on long-term growth of the Company and creation of increased stockholder value.
In 2018, the Compensation Committee decided to compare performance of the Company's stock to the Russell 3000 Index, which includes the Company. This directly aligns executives' compensation with stockholders interest because the number of shares earned depends upon performance against the Russell 3000 Index and the value of the shares fluctuates based on the stock price. For each 1% that IPG's common stock exceeds the performance of the Russell 3000 Index for the trailing 60 trading days from the end of the performance measurement period (March 1, 2021) against the comparable period from the beginning of the performance measurement period (March 1, 2018), the grant recipient would receive a 2% increase in the number of shares above target (up to a maximum share cap of 200% of the target award).
For each 1% below the Russell 3000 Index's performance, the grant recipient would receive a 2% decrease in the number of shares (down to zero). In addition, NEOs cannot receive a number of shares that exceeds 600% of the value of the target award on the date of grant. The vesting date is March 1, 2021, should any performance-based stock units vest at all.
In 2018, the Compensation Committee targeted granting equity compensation near the 65th percentile of the target compensation of our peer group, balancing the perspective of delivering competitive compensation based upon Black-Scholes option pricing values and Monte Carlo simulations for performance-based stock units. The Compensation Committee analyzed several aspects of the equity grant program, including (i) the "in the money" value, the degree to which executives have incentives to remain employed by the Company through unvested option values, and (ii) the aggregate equity usage in terms of (a) annual usage, typically called burn rate, and (b) cumulative equity delivery, typically called overhang, to determine the dilutive effect of equity awards on
33


investors. The majority of outstanding equity award holdings of the executives were allocated to unvested shares in the aggregate, and all such executives had a minimum of two years' worth of annual award values in unvested equity value. Based upon this information, Radford advised the Compensation Committee that our equity program provides strong retention incentives.
Since the Company's initial public offering in 2006, the Compensation Committee has not granted the CEO any equity compensation awards. As the Company's founder and the beneficial owner of a large number of our shares, he has the perspective of an owner with a significant financial stake in the Company's success and a long-term outlook. This practice has resulted in substantially lower total compensation earned by our CEO as compared to the chief executives of our named peers despite our outstanding business and earnings growth. In addition, this practice results in a lower compensation expense and lower equity burn rate for the Company.
The table below provides information on grants of service-based stock options, service-based restricted stock units and performance-based stock units to the NEOs in 2018. All awards in the table below vest 25% on each anniversary of March 1, 2018, except for the performance-based stock units which vest on March 1, 2021.

The Compensation Committee believes that vesting of awards of service-based options and restricted stock units over four years provides a strong incentive for executives to remain employed by us and to focus on increasing our financial performance over the long-term, while discouraging excessive short-term risk taking. The Compensation Committee believes that performance-based stock units should vest over three years, rather than four years, because having a four-year performance period would reduce the utility of the performance award and not properly align pay with performance. Service-based restricted stock units granted in 2018 may be entitled to dividends, should any be paid, at the discretion of the Compensation Committee. Any dividends on shares underlying the performance-based stock units do not vest until the performance-based stock units vest.
2019 Update. The Compensation Committee approved the grant of service-based stock options and restricted stock units and performance-based stock units to the NEOs (other than the CEO) in February 2019.  All equity awards in the table below vest as follows: service-based stock options and restricted stock units vest 25% on each anniversary of March 1, 2019 and performance-based stock units vest on March 1, 2022, the last day of the performance period which is three years after the start of the performance period. The Compensation Committee also changed the index against which the relative performance of the Company’s stock is measured for the 2019 and future awards. The Committee considered the analysis of Radford for the current peer index, the Russell 3000, and other peer index alternatives. The Committee selected the S&P Composite 1500 Electronic Equipment, Instrument and Components index as the 2019 relative stock index for the performance-based stock units because, among other reasons, it has a higher overall correlation among constituents with the Company, and the Company’s market cap, revenue and volatility are in line with the range of such measures in the index.  IPG is a member of the index.

All Other Compensation
Severance Benefits. The severance benefits we offer assist us in recruiting and retaining talented individuals and are consistent with the range of severance benefits offered by our peer group. The severance provisions of our employment agreements are summarized below in the section titled "Potential Payments upon Termination or Change in Control."
Retirement Benefits. We do not offer an executive retirement plan or a non-qualified deferred compensation plan. Executives in the United States are eligible to participate in our 401(k) retirement savings plan on the same terms as all other U.S. employees. Our 401(k) retirement savings plan is a tax-qualified plan and therefore is 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 NEOs). We made matching contributions to our employees at a rate of 50% of deferrals subject to a maximum of 6% of eligible compensation under the 401(k) retirement savings plan, including the NEOs, who participate in the plan as set forth in the Summary Compensation Table. Dr. Scherbakov, who resides in Germany, participates in a government-sponsored retirement program.
Personal Benefits. Our executives are eligible to participate in employee benefit plans, including medical, dental, life and disability insurance and vacation plans as well as an employee stock purchase plan, which is intended to be qualified under Section 423 of the Code. The employee stock purchase plan allows participants to purchase Company shares at a price equal to 85% of the lesser of the fair market value at the first day or last day of the six month offering period, subject to limitations on the amount of shares. These plans generally are available to all salaried employees and do not discriminate in favor of executives. Benefits are intended to be competitive with the overall market in order to facilitate attraction and retention of high-quality employees.
The Compensation Committee compared the Company's executive perquisites policies against the 2018 peer group and made no changes. The Company provides the use of a corporate aircraft to the CEO and other executives for business travel integral to the performance of their duties. Executives are encouraged to use the aircraft for efficiency, safety and security. However, executives are not allowed to use the aircraft for personal use that has not been paid for, except that family and other guests may accompany executives on the aircraft for business travel. The Company provides the CEO with a car and driver in the United States so that he may use his travel time for company purposes. The Company also provides Dr. Scherbakov use of an automobile, as it does for other high-ranking employees in Germany.
Role of Compensation Committee
The Compensation Committee determines, approves and administers the compensation programs for our executive officers, including our NEOs. The Compensation Committee recommends to the independent directors the CEO's annual base salary, annual incentive opportunity and long-term incentive opportunity. The independent directors approve the CEO's compensation and our Compensation Committee approves the compensation for other executive officers in consultation with our CEO. Our Compensation Committee is also responsible for making recommendations to the Board with respect to the adoption of equity plans and certain other benefit plans.
The Compensation Committee may delegate authority whenever it deems appropriate. In 2018 the Compensation Committee delegated authority to grant equity awards for non-executives to the CEO subject to certain conditions including amounts of awards and review of awards by the Compensation Committee.
Our Compensation Committee's policy is to set executive pay in accordance with the objectives of the Company's compensation programs as described above. In the Compensation Committee's view, the Company's executive compensation program provides an overall level of compensation opportunity that is competitive with peer companies. Actual compensation levels may be greater or less than target compensation levels provided by similar companies based upon annual and long-term Company performance, as well as individual performance, contributions, skills, seniority, knowledge, experience and responsibilities.
Role of Management  
The CEO participates in the establishment of the compensation targets and payout levels for the other NEOs. He assesses the performance of all NEOs and recommends to the Compensation Committee the overall levels of achievement, and personal performance in the year. Upon request, the NEOs provide supplemental material to the Compensation Committee to assist in the determination and implementation of compensation, policies and practices. The CEO is not involved in decisions regarding the setting of any component of his compensation. The CEO and other members of senior management attend Compensation Committee meetings at the invitation of the Compensation Committee.
35


Role of Independent Consultant
The Compensation Committee engaged Radford, an independent compensation consultant, to conduct a comprehensive review and analysis of our executive and non-employee director compensation programs and to make recommendations for compensation related to 2018. The consultation included non-executive compensation data and valuation services for equity incentives. Radford’s parent company does not perform any other work for the Company. The Compensation Committee reviews the independence of Radford in light of SEC rules and Nasdaq listing standards regarding compensation consultants. The Compensation Committee believes that there were no actual or potential conflicts of interest with Radford in 2018.
Pay Positioning Strategy
Consistent with prior years, the Compensation Committee in 2018 set the market 65th percentile as its target for base salary, target annual bonus, long-term incentives and total direct compensation (the sum of the three compensation elements).  Also, competitive target ranges for the elements and target total direct compensation were established. Within the comparative framework, the primary data was the named peer group of specific peers discussed below and the secondary data was broader, size-appropriate comparisons in the high technology industry using Radford High Technology Survey Data. In 2018, the midpoint of the Company's target total cash compensation range was near the 65th percentile. An individual's actual compensation may fall below or above the target positions based on the individual's experience, seniority, skills, knowledge, performance, responsibilities and contributions as well as the Company's performance.
These factors are weighed by the Compensation Committee in its judgment, and no single factor takes precedence over others nor is any formula used in making these decisions.
In analyzing our executive compensation program relative to this target market positioning, the Compensation Committee utilizes a comparative analysis of the compensation of our executives measured against a group of peer companies selected by the Compensation Committee. The peer companies are companies in the laser source and photonics industry, as well as a broader group of technology companies of comparable size and complexity with international scope that experience growth.
For 2018, the peer companies were:
Arista Networks, Inc.Barnes Group, Inc.Cognex Corporation
Coherent, Inc.Dolby Laboratories, Inc.Donaldson Company, Inc.
Entegris, Inc.FLIR Systems, Inc.Graco, Inc.
IDEX CorporationII-VI IncorporatedITT, Inc.
MKS Instruments, Inc.National Instruments, Inc.Nordson Corporation
Teradyne, Inc.Trimble Navigation LimitedWaters Corporation
Zebra Technologies, Inc.

The Compensation Committee reviews this peer group annually with input from Radford to ensure that the comparisons are meaningful. In this review, the Compensation Committee considers several factors in developing a peer group: it considers the current peer group to determine appropriateness, the peers used by institutional governance advisors, the companies that list our company as peer to understand crossover peers and broader research based upon established selection criteria to identify potential future peers. The Committee then develops criteria for business sector, market capitalization, revenue and headcount. Radford also supplements its peer analysis with the data from a broader list of high-technology public company participants in the AON Radford Executive Technology Survey targeting technology companies with comparable revenue levels. Companies that are no longer publicly traded have been omitted from the peer group. Based upon the process and applying the criteria above, the Compensation Committee (i) added Arista Networks, Inc., Donaldson Company, Inc. and Waters Corporation to the peer group and (ii) removed Fabrinet and OSI Systems, Inc. from the peer group.
2019 Update. For 2019 compensation determinations, the Compensation Committee applied the methodology above and determined the historical peer group continues to be appropriate for 2019.

36


Other Factors Affecting Compensation
Tax Deductibility under Section 162(m).  Section 162(m) of the Internal Revenue Code ("Section 162(m)") limits the deductibility for federal income tax purposes of certain compensation paid in any year by a publicly held corporation to its "covered employees" as defined by Section 162(m) (generally, our current and former NEOs) to $1 million per executive (the "$1 million cap"). Prior to the enactment of the Tax Cuts and Jobs Act (“TCJA”), Section 162(m) provided an exception from this deduction limitation for certain forms of “performance-based compensation,” which included annual incentive payments, the gain recognized by NEOs upon the exercise of stock options and the income recognized on the vesting of performance share awards. Due to the TCJA, the "performance-based" compensation exception to the $1 million cap does not apply for tax years after 2017, unless certain limited transition relief is met. The Compensation Committee retains the discretion to grant or pay compensation that may exceed the $1 million cap or may not qualify for the performance-based compensation exception to Section 162(m). The Compensation Committee believes it is appropriate to retain the flexibility to authorize payments of compensation that may not qualify for deductibility if, in the Compensation Committee's judgment, it is in the Company’s best interest to do so. In the past, the Compensation Committee generally sought to structure performance-based compensation for our covered employees, and to undertake the required ministerial actions, in a manner that complies with Section 162(m) in order to provide for the deductibility of such compensation to the extent possible. We generally will continue to emphasize performance-based compensation, even though it may no longer be deductible.
Accounting Considerations. We consider the accounting implications of our executive compensation program. In addition, accounting treatment is just one of many factors impacting plan design and pay determinations. Our executive compensation program is designed to achieve a favorable accounting and tax treatment as long as doing so does not conflict with the intended plan design or program objectives.
Compensation Risk
Management conducts an annual risk assessment of the Company's compensation policies and practices for all employees, including non-executives, and reports its findings to the Compensation Committee. In 2018, management concluded that the Company's compensation policies and practices are balanced and do not motivate imprudent risk taking. Management believes that IPG’s compensation policies do not create risks that are reasonably likely to have a material adverse effect on IPG.
In reaching this conclusion, they considered the following factors:
our compensation program is designed to provide a mix of both fixed and variable incentive compensation; 
our senior executives are subject to stock ownership guidelines, which we believe incentivize our executives to consider the long-term interests of the Company and our stockholders and discourage excessive risk-taking that could negatively impact our stock price;
our senior executives are subject to compensation recovery policy, which discourages excessive risk-taking that could negatively affect our stock price;  
our incentive compensation programs are designed with vesting terms that are relatively consistent, spread out over several years, and do not contain steep payout "cliffs" that might encourage short-term business decisions in order to meet a vesting or payout threshold; and
our senior executive incentive compensation program caps the amounts that may be paid for performance above target level.
Other Policies
Anti-Hedging and Limitations on Pledging of Company Stock. The Board adopted policies prohibiting hedging transactions and limiting the pledging of our common stock. Under our insider trading policy, no director or employee may engage in shorting shares of our common stock or any type of securities that we may issue, or buying or selling puts, calls or derivatives related to our common stock. A director or officer of the Company may not pledge shares constituting more than 20% of his or her total stock ownership. Pledges of shares constituting 20% or less of total stock ownership are subject to certain conditions. 

Stock Ownership Guidelines. The Board adopted stock ownership guidelines to closely align the interests of our executives with those of our long-term stockholders. Under the guidelines, the CEO is expected to maintain a minimum investment on our common stock of five times his annual salary and other senior executives are expected to maintain a minimum investment on our common stock of the lesser of 5,000 shares or one times their respective
37


annual salaries. All of our senior executives substantially exceed the ownership requirements under our stock ownership guidelines. These ownership levels are to be achieved no later than four years after the election as an executive officer, except that prior to such time the officer is expected to retain a certain portion of stock issued upon exercise of stock options or vesting of restricted stock awards until the minimum ownership levels are attained. For more information, see "Corporate Governance - Stock Ownership Guidelines."

Clawback Policies. In 2015, the Compensation Committee approved a compensation recovery policy that allows the Company to recapture performance-based compensation from executives if the amount of the award was based upon achieving certain financial results that were later restated due to the participant's misconduct. In addition, all equity awarded to employees since 2007 contain a provision under which employees may be required to forfeit equity awards or profit from equity awards if they engage in certain conduct, including competing against the Company, disclosing confidential information, or soliciting its employees or customers.

1.Valuation based on the fair value of such award as of the grant date determined pursuant to Financial Accounting Standards Board Accounting Standards Codification Topic 718 ("ASC Topic 718"). The assumptions that we used with respect to the valuation of service-based restricted stock units, performance-based stock units and stock option awards are set forth in Note 12 to our Consolidated Financial Statements in our Annual Report on Form 10-K filed with the SEC on February 27, 2019. The amounts in the Stock Awards column reflect service-based restricted stock units and performance-based stock units granted in 2018.
