PROPOSAL ONE

ELECTION OF DIRECTORS

At the Annual Meeting, the stockholders will elect eleven directors to serve until the 20192020 Annual Meeting and until their successors are elected and qualified. The Board of Directors, based upon the recommendation of the Corporate Governance and Nominating Committee (the “Governance Committee”), has designated as nominees for election the eleven individuals named in the table below, all of whom currently serve as directors.

In nominating each of the director nominees, the Governance Committee and the Board considered, among other things, the Board’s Corporate Governance Guidelines, and Qualifications for Nomination to the Board, which werewas adopted in 2004 and most recently amended in March 2018.2018, and the Qualifications for Nomination to the Board, which was adopted in 2004. These documents are posted on our website atwww.3DSystems.com. These qualifications include, among other factors, a candidate’s ethical character, experience and diversity of background as well as whether the candidate is independent under applicable listing standards and financially literate. In considering the nomination of these individuals, the Governance Committee and the Board also took into consideration the following additional factors relating to each director since the 20172018 Annual Meeting:

Relevant information regarding the background and experience of each of the nominees for director that the Governance Committee and the Board considered in evaluating each nominee is set forth oppositebelow their respective names in “Information Concerning Nominees” below. See also “Corporate Governance Matters” below, which discloses additional information about the nominees and our corporate governance policies and practices.

The Governance Committee and the Board considered each nominee’s overall business experience, contributions to Board activities during 20172018 and independence in their evaluation of each nominee in conjunction with the factors discussed above, but did not otherwise give greater weight to any of the factors cited above compared with any of the others. While the Board considers diversity of background and experience in its nomination decisions, we do not maintain a diversity policy relating to the composition of our Board of

Directors. The Board believes that each of the nominees for director is well qualified to continue to serve as a director of the Company and that the nominees provide the mix of experience that is required to enable the Board to perform its functions.

If any nominee becomes unavailable for any reason or if a vacancy should occur before the election (which events are not anticipated), the holders of proxies may vote the shares represented by such duly executed proxies in favor of such other person as they may determine. Alternatively, in lieu of designating a substitute, the Board may reduce the number of directors.

Information Concerning Nominees

The following table sets forth for each nominee for director, his or her business experience, the year in which he or she first became a director, his or her age as of the record date for the Annual Meeting, and any directorships in publicly owned companies or registered investment companies that such nominee currently holds or has held during the past five years.

CORPORATE GOVERNANCE MATTERS

Our Board of Directors is committed to sound and effective corporate governance practices, to diligently exercising its oversight responsibilities with respect to our business and affairs consistent with the highest principles of business ethics, and to meeting the corporate governance requirements that apply to us.

Corporate Governance Guidelines

The Board has adopted Corporate Governance Guidelines that address various governance matters, including, among others, the functions of the Board, Board committees, director qualification standards and the director nomination process; director responsibilities; director access to management and independent advisors; director stock ownership; director orientation and continuing education; management succession; and an annual performance evaluation of the Board. The Governance Committee is responsible for overseeing these Guidelines, periodically assessing their adequacy, and modifying them to meet new circumstances. These Guidelines are posted on our website atwww.3DSystems.com under “Investor Relations,” and then under “Governance.”

Director Independence

Eight of our eleven directors are independent directors. Under the corporate governance standards of the New York Stock Exchange (the “NYSE”), at least a majority of our directors, and all of the members of the Audit Committee, Compensation Committee, and Governance Committee, must meet the test of “independence.” The NYSE standards provide that, to qualify as an “independent” director, in addition to satisfying certain bright-line criteria, the Board must affirmatively determine that a director has no material relationship with us (either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company). The Board has affirmatively determined that Ms. Clinton and Messrs. Curran, Humes, Kever, Loewenbaum, McClure, Moore, Tracy and Wadsworth satisfy the bright-line criteria of the listing standards of the NYSE and that they have no material relationships with us. In making its determination, the Board and the Governance Committee reviewed the related party transactions relating to Mr. Humes that are disclosed underRelated Party Transaction Policy and Procedures beginning on page 16 of this Proxy Statement, and the following relationships:

Mr. Joshi, our Chief Executive Officer (“CEO”), and Mr. Chuck Hull, one of our founders and our Chief Technology Officer, are executive officers of the Company and, as such, are not independent directors.

Mr. Erickson, who was appointed to the Board on November 17, 2015, was party to a consulting agreement with the Company in 2016, as described further under “Related Party Transaction Policy and ProceduresProcedures” beginning on page 1617 of this Proxy Statement and, as such, is not an independent director.

Risk Responsibility and Oversight

Consistent with Delaware law, our business is managed by our officers under the direction and oversight of the Board of Directors. In this regard, our management, including our corporate officers, is responsible for theday-to-day management of the risks facing us, including macroeconomic, financial, strategic, operational, public reporting, legal, regulatory, political, compliance, and reputational risks. They carry out this responsibility through a coordinated effort among themselves in the management of our business.

In exercising its oversight responsibilities, as permitted by law, the Board receives and relies on reports and other information provided by management, reviews, and approves matters that it is required or permitted to approve by law or our Certificate of Incorporation orBy-Laws, each as amended, and receives information relating to, and enquires into, such other matters as it deems appropriate, including our business plans, prospects and performance, succession planning, risk management, and other matters for which it has oversight responsibility. The Board carries out its general oversight responsibility both by acting as a whole as well as through its committees. Among other things, the Board as a whole periodically reviews our processes for identifying, ranking, and assessing risks that affect our organization as well as the output of those processes. The Board as a whole also receives periodic reports from our management on various risks, including risks of the types mentioned above facing our businesses, risks presented by transactions that are presented to the Board for approval, and risks arising out of our corporate strategy.

11

As discussed below, the Board also maintains several standing committees with oversight responsibility for various Board functions. Although the Board has ultimate responsibility for overseeing risk, its standing committees perform certain of its oversight responsibilities. For example, in accordance with its charter, the Audit Committee engages in ongoing discussions regarding major financial and accounting risk exposures and the process and system employed to monitor and control such exposures. In addition, consistent with its charter, the Audit Committee engages in periodic discussions with management concerning the process by which risk assessment and management are undertaken, and it exercises oversight with regard to the risk assessment and management processes related to, among other things, internal controls, credit, capital structure, liquidity, cybersecurity and insurance programs. In carrying out these responsibilities, the Audit Committee, among other things, regularly reviews with the Internal Audit Director the audits or assessments of significant accounting and audit risks conducted by Internal Audit personnel based on their audit plan, and the Audit Committee regularly meets in executive sessions with the Internal Audit Director. The Audit Committee also regularly reviews with management our internal control over financial reporting, including any significant deficiencies or material weaknesses. As part of these reviews, the Audit Committee reviews steps taken by management to monitor, control and mitigate risks. The Audit Committee also regularly reviews with the Chief Legal Officer significant legal, regulatory and compliance matters that could have a material impact on our financial statements or business. Finally, from time to time executives who are responsible for managing particular risks report to the Audit Committee on how those risks are being controlled and mitigated.

Other Board committees also exercise responsibility to oversee risk within their areas of responsibility and expertise. For example, as noted in the section below entitled “Risk Assessment of Compensation Policies and Practices,” the Compensation Committee oversees risk assessment and management with respect to our compensation policies and practices, and it exercises oversight with respect to our 401(k) plan.

In those cases in which committees have risk oversight responsibilities, the Chairs of the committees regularly report to the full Board the significant risks facing the Company, as identified by management, and the measures undertaken by management for controlling and mitigating those risks.

Risk Assessment of Compensation Policies and Practices

We have reviewed our material compensation policies and practices, discussed the concept of risk as it is related to our compensation program, and considered various mitigating factors. Based on these reviews and discussion, the Compensation Committee does not believe our compensation program creates risks that are reasonably likely to have a material adverse effect on our business.

For more information regarding our compensation program, see the section of this Proxy Statement titled “Compensation Discussion & Analysis.”

Board Leadership Structure

The Board has separated the position of its Chairman from the position of CEO.Chief Executive Officer (“CEO”). As noted above, Mr. Loewenbaum,McClure, an independent director, serves as Chairman of the Board of Directors. Mr. McClure was appointed Chairman on October 3, 2018 following the retirement of G. Walter Loewenbaum, II from the Board. Mr. Loewenbaum served as Chairman of the Board of Directors since 1999.

Nevertheless, weWe do not have a policy regarding whether the Chairman and CEO roles should be combined or separated. Rather, our Board of Directors prefers to retain flexibility to choose its leadership structure and Chairman in any way that it deems best for the Company at any given time. The Board periodically reviews the appropriateness and effectiveness of its leadership structure given numerous factors. Currently, the Board believes that it is appropriate for Mr. LoewenbaumMcClure to remain as Chairman given his independence as a director, his backgroundbroad experience in domestic and international operations management, deep experience in executive management and hisdirector roles within publicly traded companies, and significant holdings of our Common Stock, which enable him to reflect the views of stockholdersexpertise in the deliberations ofautomotive industry, a key vertical for the Board of Directors.Company. With the foregoing in mind, the Board believes that the current Board leadership structure has promoted decisive leadership, ensured clear accountability, and enhanced our abilityallows Mr. Joshi to communicate with a consistent voicefocus on managing the daily operations of the Company in his role as CEO, while permitting Mr. McClure to stockholders, customers, employees, and other stakeholders.oversee the Board’s significant functions. The Board also believes that it has assisted in the efficient conduct of Board meetings as the directors discuss key business and strategic matters and other critical issues.

It also prohibits transactions in publicly traded options, such as puts, calls, and other derivative securities, or other hedging transactions on a securities exchange or other organized market. Our Insider Trading Policy requires that our directors and executive officerspre-clear any transactions in our securities with our Chief Legal Officer or Assistant General Counsel.

In addition, each award granted under the 2015 Incentive Plan is subject to the condition that we may require that such award be returned, and that any payment made with respect to such award must be repaid, if such action is required under the terms of any recoupment or “clawback” policy of ours as in effect on the date that the payment was made, or on the date the award was granted or exercised or vested or earned, as applicable.

DIRECTOR COMPENSATION

Director Compensation for 20172018

The following table sets forth information concerning all compensation of each of ournon-employee directors for their services as a director during the year ended December 31, 2017.2018. Ms. Clinton was appointed to the Board in March 2019; therefore, she did not receive any compensation as a director during the year ended December 31, 2018.

As discussed below,non-employee directors also receive annual equity awards. We also reimburse directors for their expenses of attendance at meetings of the Board of Directors or its committees.

Directors who are employees of the Company (Mr. Joshi and Mr. Hull) receive no additional compensation for service as a director.

Director Equity Awards

Director equity compensation is set by the Board, based upon the recommendation of the Governance Committee. Equity awards granted to our directors are made under the Directors Stock Plan and 2015 Incentive Plan described in further detail below. The equity compensation policy fornon-employee directors provides for annual grants of restricted stock to each director equal to $100,000 in total value. Pursuant to this policy, each director in office on the date of the 20172018 Annual Meeting was granted 4,2907,758 shares of restricted stock. Because our Directors Stock Plan limits the number of equity awards that may be granted to any director in a single year to 3,000 shares, equity awards made to ournon-employee directors were comprised of a grant of 3,000 shares under the Directors Stock Plan and a grant of 1,2904,758 shares under the 2015 Incentive Plan. Additionally, Mr. McClure, Dr. Tracy, and Dr. Wadsworth each received initial grants of 1,000 shares upon joining the Board and prorated annual awards for partial years served. All shares of Common Stock issued to directors as compensation for their services as directors are fully vested when issued.

Notwithstanding the stock grant amounts described above, the Directors Stock Plan limits the value of any award of shares made to an eligible director to $100,000 valued on the date of the award.

As a condition of each award under the Directors Stock Plan, each participant is required to pay an issue price equal to the $0.001 par value per share of Common Stock issued under the Directors Stock Plan, to execute an agreement to hold the shares covered by such grant in accordance with the terms and conditions of the Directors Stock Plan (including, without limitation, restrictions on transferability provided for in the Directors Stock Plan) and to comply with certain other terms and conditions of the grant. Except in limited circumstances provided for in the Directors Stock Plan, aNon-Employee Director is not permitted to sell, transfer, pledge, or otherwise dispose of shares of Common Stock awarded under the Directors Stock Plan as long as (a) theNon-Employee Director remains a director of the Company or (b) a change of control as provided for in the Directors Stock Plan has not occurred.Non-Employee Directors who hold shares of Common Stock under the Directors Stock Plan are entitled to voting rights and any dividends paid with respect to such shares. Shares of Common Stock issued under the Directors Stock Plan are fully vested when issued. Excluding grants to newly-elected directors, the Directors Stock Plan limits the number of equity awards that may be granted to any director in a single year to 3,000 shares.

The Directors Stock Plan authorizes the issuance of up to 600,000 shares of Common Stock for awards under the Directors Stock Plan, subject to further adjustment in the event of changes in the Common Stock by reason of any stock dividend, stock split, combination of shares, reclassification, recapitalization, merger, consolidation, reorganization, or liquidation. At December 31, 2017, 50,1362018, 23,136 shares of Common Stock remained available for issuance under this Directors Stock Plan.

The Directors Stock Plan does not prevent the Board of Directors from exercising its authority to approve the payment of additional fees to members of the Board of Directors, to adopt additional plans or arrangements relating to the compensation of directors or to amend the existing cash fees paid to directors.

2015 Incentive Plan

Non-Employee Directors are also eligible to receive grants of Common Stock under the 2015 Incentive Plan, which was approved by our stockholders in May 2015 and amended and restated in May 2017. Subject to adjustment from time to time, not more than 10,000 shares of Common Stock, in the aggregate, may be made subject to awards under the 2015 Incentive Plan in respect of anyNon-Employee Director during any year; provided, however, that up to 50,000 shares of Common Stock, in the aggregate, may be made subject to awards under the 2015 Incentive Plan during any year in respect of anyNon-Employee Director who also provides consulting or other services to the Company in addition to the services provided as a member of the Board.

The 2015 Incentive Plan authorizes the issuance of up to 6,300,000 shares of Common Stock for awards under the 2015 Incentive Plan, subject to further adjustment in the event of changes in the Common Stock by reason of any stock dividend, stock split, combination of shares, reclassification, recapitalization, merger, consolidation, reorganization, or liquidation. At December 31, 2018, 4,854,649 shares of Common Stock remained available for issuance under this 2015 Incentive Plan.

EMPLOYEE COMPENSATION MATTERS

We maintain a compensation program for all of our employees that is based upon the following objectives:

We use the same principles in attracting and retaining our executives. In 2017, we established a consistent and unified market-based job architecture that now serves as the framework for all employee compensation decisions Company-wide.

All of our employees receive either fixed annual salaries or hourly wages for their services. Certain of them, including our executive officers, participate in annual incentive compensation programs that are approved by the Board of Directors or its committees as part of our annual budgeting process, and participants in those programs have fixed incentive compensation targets that are approved in advance. See “Executive Compensation” below. Other employees receive commissions atpre-established rates based on their sales or related customer activities that are intended to provide incentives to their achieving previously approved sales or service objectives.

Except with respect to his own compensation, our CEO oversees our employee compensation programs and makes recommendations to the Compensation Committee with respect to the compensation of each of his direct reports and other employees with base annual salaries of $300,000 or more. Generally, the manager of each reporting unit is annually allocated a salary pool for such reporting unit, and the manager determines how to allocate this pool among the employees in the reporting unit. Our annual incentive pool, if funded, is intended to be allocated similarly among reporting units for reporting unit managers to allocate among the employees in such reporting unit. Our CEO establishes target incentive bonuses for the current calendar year for each of his direct reports, and the manager of each reporting unit establishes target incentive bonuses for the current calendar year for each employee in the reporting unit eligible to participate in the annual incentive program. All employee compensation decisions by the CEO and reporting unit managers are now guided by the market-based job architecture established in 2017.

As discussed above under “Corporate Governance Matters – Risk Assessment of Compensation Policies and Practices”, we believe that our compensation practices do not create inappropriate or unintended risks and that any such risks that do exist are not reasonably likely to result in a material adverse effect on us. We endeavor to manage any of these risks that may arise through our system of internal financial and operational controls and our Board and management oversight processes.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This Compensation Discussion and Analysis provides detailed information and analysis regarding the compensation of our named executive officers as reported in the Summary Compensation Table and other tables located in the “Executive Compensation” section of this Proxy Statement.

Summary of Key 20172018 Compensation Actions

Our Executive Compensation Philosophy

Our executive compensation program, practices and policies have been structured to reflect the Board’s commitment to excellence in corporate governance, and to align rewards with achievement of short- and long-term performance objectives that drive stockholder value. The compensation we pay to employees is generally subject to the same principles and guidelines that apply to our executive compensation program. Nevertheless, the following is a discussion and analysis of the material elements of our compensation programs as it relates to the NEOs.

Determining Executive Compensation

The Compensation Committee is responsible for setting the compensation of all executive officers, including the NEOs. It is also responsible for setting the compensation of any other employees of the Company or our subsidiaries who report directly to our CEO or have base annual salaries of $300,000 or more. For additional information about the responsibilities of this Committee, see“Corporate Governance Matters – Compensation Committee”above.

The Compensation Committee reviews the CEO’s recommendation for each of the other NEO’s compensation during the first quarter of each year. The purpose of this annual review is:

As part of this review, our CEO gives the Compensation Committee a recommendation for incentive compensation awards for the prior year, salary adjustments for the current year and target incentive bonuses for the current year for each other NEO. In 2017, we established a new market-based job architecture for all employees to ensure appropriate levels of pay at each employee classification across the Company. Additionally, concrete personal objectives were established for each NEO by which such executive’s individual performance is measured. Our CEO uses the market-based job architecture and evaluation of each individual NEO’s progress towards assigned strategic imperatives and concrete personal objectives to guide his compensation recommendations to the Compensation Committee. The Compensation Committee reviews those recommendations and modifies them to the extent it considers appropriate. As part of this process, the Compensation Committee approves the amount of any annual incentive compensation to be awarded to each individual with respect to the preceding calendar year, approves the amount of any adjustments to be made to the annual salary of each such individual for the current year, approves the terms of our incentive compensation program for the current calendar year, and establishes target incentive bonuses for the current year for each of our NEOs and each of the other individuals whose compensation it oversees. The Compensation Committee may also approve adjustments to compensation for specific individuals at other times during any year when there are significant changes in the responsibilities of such individuals or under other circumstances that the Compensation Committee considers appropriate.

Our CEO’s compensation is determined under similar principles but follows a different process. This process is designed to comply with applicable law and listing requirements under which, after discussing his self-evaluation with him and receiving the views of other independent directors, the Compensation Committee evaluates his performance, reviews the Compensation Committee’s evaluation with him, and, based on that evaluation and review, determines his compensation and personal annual incentive objectives. Our CEO is excused from meetings of the Compensation Committee during voting or deliberations regarding his compensation.

*No annual incentive awards were paid with respect to 2018. See“2018 Incentive Compensation Program” for further details.

**41% of the target 2018 performance based equity awards were earned.

Base Salaries

We pay annual salaries to provide executives, including the NEOs, with a base level of monthly compensation for services rendered during the year. Salaries are also designed to help achieve our objectives of attracting and retaining executive talent. Adjustments to base salaries are based on the Company’s market-based job architecture, which takes into consideration the responsibilities of the executives, the Compensation Committee’s evaluation of the market demand for executives with similar capability and experience, and each individual NEO’s progress towards assigned strategic imperatives and concrete personal objectives.

Annual Incentive Program

Our annual incentive compensation program is designed to provide appropriate incentives to reward performance and motivate our executives, including the NEOs, to attain our strategic objectives.

This program is adopted annually, is designed with our strategic objectives in mind, and has historically focused partly on the achievement ofpre-determined corporate financial objectives and partly, for each executive, on personal objectives. Prior to 2017, 55% of each executive’s annual incentive compensation target was based on the achievement ofpre-approved corporate financial objectives with the remaining 45% based on the achievement of personal objectives.

In 2017, our Compensation Committee revised our annual incentive compensation program so that the pool available for payout thereunder is based 100% on the achievement ofpre-determined corporate financial objectives. Under the new annual incentive compensation program, if thepre-determined corporate financial objectives are achieved and the pool is funded, the allocation of the pool among participants is based on each participant’s progress towards assigned strategic-imperatives and concrete personal objectives. If thepre-determined corporate financial objectives are not achieved, no employees receive awards under our annual incentive compensation program. Even if thepre-determined corporate financial objectives are achieved, our Compensation Committee always retains the discretion to reduce the funding of the Company-wide annual incentive plan pool or any individual participant’s award.

As an overriding condition, a failure to perform in accordance with our Code of Conduct or Code of Ethics may serve as a basis for a participant in this program not to receive an incentive award. We consider this aspect of our incentive compensation program to be consistent with sound principles of corporate governance.

27

As part of its goal-setting process, the Compensation Committee establishes current-year target incentive awards for each NEO with the following principles in mind:

Financial objectives are determined based on our business plan for the year in question. This business plan is developed by management and approved by the Board of Directors. Concrete personal objectives for all NEOs, other than the CEO, are developed through collaboration between each NEO and the CEO. The CEO’s personal objectives are reviewed and approved by the Compensation Committee. The Compensation Committee maintains the ability to adjust performance objectives for extraordinary items and other items as it deems appropriate.

With respect to financial measures, 100% of each NEO’s bonus related to each financial measure would generally be deemed to have been earned if the target for that financial measure is fully achieved.

Each NEO’s performance is measured against his personal objectives, and such performance is used to determine the allocation of the bonus pool if, and only if, the pool is funded by the Company’s achievement of thepre-determined corporate financial objectives.

For a discussion of the 20172018 Annual Incentive Program, see below at “—20172018 Incentive Compensation Program.”

Long-Term Equity Compensation

The Compensation Committee administers our 2015 Incentive Plan. Under the 2015 Incentive Plan, the Compensation Committee is authorized to grant restricted stock awards, restricted stock units, stock options and other awards that are provided for under the 2015 Incentive Plan to such of our employees and employees of our subsidiaries as the Compensation Committee determines to be eligible for awards. Awards granted to a participant are based upon a number of factors, including the recipient’s position, salary and performance as well as our overall corporate performance.

The 2015 Incentive Plan is intended to provide an effective method of motivating performance from key employees, including our NEOs, and of creating an alignment of interests in participants with the interests of our stockholders. Awards are made under the 2015 Incentive Plan as long-term incentive compensation to NEOs and other key employees when the Compensation Committee believes such awards are appropriate.

The Compensation Committee makes awards under the 2015 Incentive Plan both to reward performance and to motivate the recipient’s long-term performance. Historically, the majority of the equity awards made to our executive officers under the Plans2015 Incentive Plan have been restricted stock awards with time-based vesting conditions. In 2016,

28

our Committee granted stock options and restricted stock awards with share price-based vesting conditions under the 2015 Incentive Plan. The equity awards with share price-based vesting conditions granted to our NEOs in 2016 do not vest until the closing price of our Common Stock on each of the trading days during the immediately prior ninety consecutive calendar days is at least $30 or $40, as applicable, representing a significant increase in market capitalization as compared to the closing price of our Common Stock on the date of grant.

conditions. As mentioned above, the Compensation Committee engaged Pearl Meyer in 2017 to assist the Committee in its review and evaluation of the compensation for the executive officers. Consequent to the Compensation Committee’s comprehensive review, we granted restricted stock awards with time-based vesting conditions to our executive officers, including our NEOs, in December 2017 and performance share units in February 2018. The performance share units were granted in February 2018 so that we could review more current perspectives on our business outlook and budgeting process when establishing revenue and operating income performance targets. These performance share unit awards willcould only be earned by the NEOs only upon our achievement ofpre-determined levels of 2018 revenue and operating income. If earned,A portion of the performance share unit awards were earned based on 2018 revenue and operating income; such awards vest in three equal annual installments.

In 2016, our Compensation Committee granted stock options and restricted stock awards with share price-based vesting conditions under the 2015 Incentive Plan. The equity awards with share price-based vesting conditions granted to our NEOs in 2016 do not vest until the closing price of our Common Stock on each of the trading days during the immediately prior ninety consecutive calendar days is at least $30 or $40, as applicable, representing a significant increase in market capitalization as compared to the closing price of our Common Stock on the date of grant.

Restricted stock awards and performance share unit awards issued pursuant to the 2015 Incentive Plan remain subject to forfeiture until the vesting of such shares pursuant to the terms of the applicable award. Stock options made under the 2015 Incentive Plan generally have a 10 year term and an exercise price based on the fair market value of our Common Stock on the date of grant.

Shares of restricted stock, performance share units and stock options issued pursuant to the 2015 Incentive Plan may not be sold, transferred or encumbered by the employee prior to vesting (and exercise in the case of stock options). The compensation associated with these awards is expensed over the vesting period. The shares covered by restricted stock awards are considered outstanding upon issuance following the acceptance of each award for the purpose of calculating diluted earnings per common share, and holders of shares issued pursuant to restricted stock awards are entitled to vote such shares and to receive any dividends declared in respect of our Common Stock. Shares covered by performance share units are not considered outstanding until vested and shares covered by stock option awards are not considered outstanding until exercise except, in each case, for the purpose of calculating diluted earnings per common share. The holders of performance share units and stock options are not entitled to vote shares or receive any dividends declared with respect to the shares covered by such awards.

20172018 Salaries

At its meeting on March 27, 2017,22, 2018, the Compensation Committee determined not to make any changes toincrease the base salaries of our NEOs in 2017.2018. The current2018 and 2017 base salaries of our NEOs are as follows:

29

20172018 Incentive Compensation Program

Consistent with the principles discussed above, at its meetings on February 6, 2017 and March 27, 2017,22, 2018, the Compensation Committee approved an annual incentive program for 2017.2018. The 20172018 target incentive awards for each the participating NEOs were set at 50% of their 20172018 annual base salaries, except for Mr. Joshi, whose 20172018 target incentive award was set at 100% of his 20172018 annual base salary. The 20172018 threshold and maximum annual incentive award for all NEOs were set at 50% and 150%, respectively, of the target annual incentive award.

On March 1, 2019, following the finalization of the Company’s 2018 audited financials, the Compensation Committee determined that, based on the Company’s actual 2018 revenue and operating income, 41% of the target performance share units were earned by each NEO.

Employment Agreements and Other Agreements with NEOs

In April 2016 and July 2016, Vyomesh I. Joshi and John N. McMullen joined the Company as our President and CEO and Executive Vice President and Chief Financial Officer, respectively. In connection with each of these appointments, we entered into an employment agreement under which we have agreed to certain compensation arrangements and severance benefits. With the purpose of retaining our key executive officers during a significant management transition, we entered into similar employment agreements with each of Messrs. Hull and Johnson in 2016. Mr. McAlea has an existing severance agreement with the Company.

Each of these agreements was determined based on negotiations with the applicable NEO and taking into account his background and qualifications and the nature of his position. We believe that these compensation packages are appropriate in light of the intense competition for top executives in our industry and among similarly-situated companies, and that the terms of these arrangements are consistent with our executive compensation goals, including the balancing of short-term and long-term compensation to properly motivate our NEOs.

Vyomesh I. Joshi

Mr. Joshi’s employment agreement provides for a minimum base annual salary of $925,000 and a minimum target bonus opportunity of 100% of his base salary, with the exact amount of any such bonus to be based upon the achievement of performance goals to be determined by the Compensation Committee. The employment agreement entitles Mr. Joshi to participate in all other benefits generally available to our other executive employees, including participation in the Company’s health benefit plans and equity award programs. Pursuant to the employment agreement entered into in connection with his hiring in April 2016, Mr. Joshi was also granted the following equity awards: (1) 150,000 shares of restricted stock that vest in three equal annual installments; (2) 500,000 stock option awards, comprised half of option awards subject to $30 per share price-based vesting conditions and half of option awards subject to $40 per share price-based vesting conditions; and (3) 75,000 shares of restricted stock, 50,000 of which are subject to $30 per share price-based vesting conditions and 25,000 of which shares are subject to $40 per share price-based vesting conditions.

Change of Control Severance Policy

On February 22, 2018, the Compensation Committee adopted the Company’s Change of Control Severance Policy (the “COC Severance Policy”). The COC Severance Policy is intended to provide eligible officers with reasonable financial security in their employment and position with the Company, without distraction from uncertainties regarding their employment created by the possibility of a potential or actual change of control. The COC Severance Policy applies to our Chief Executive Officer and all Executive Vice Presidents and Senior Vice Presidents (each, a “Participant”), which includes all of our NEOs. For a more detailed discussion of the benefits payable to our NEOs under the COC Severance Policy, see “Potential Benefits upon Termination or Change of Control” beginning on page 3739 below.

Other Compensation Matters

Benefits and Perquisites

We provide our employees, including the NEOs, with a benefit program that we believe is reasonable, competitive and consistent with the objectives of our compensation program. As a matter of policy, the Compensation Committee does not award personal benefits or perquisites to our NEOs that are unrelated to our business. However, under certain circumstances discussed below, the Compensation Committee has approved certain personal benefits or perquisites that are either provided to ana NEO by contract or that it deemed to be in our interests in order to induce executives to commence or maintain employment with us. Those amounts are reported in the Summary Compensation Table. All other perquisites for the NEOs amount to less than $10,000 per person.

Our executives, including the NEOs, are eligible to participate in employee benefit programs that we provide to our employees generally, which include a group insurance program providing group health, dental, vision, life and long-term disability insurance. Other benefits include a Section 401(k) plan, health savings accounts, flexible spending accounts for health and dependent care expenses, sick leave, holiday time and vacation time.

Accounting and Tax Considerations

The Compensation Committee generally considers the financial accounting implications of stock awards and other compensation to the Company’s executive officers in evaluating and establishing the Company’s compensation policies and practices. Section 162(m) of the Code limits to $1 million the U.S. federal income tax deductibility of compensation paid in one year to certain covered employees, including a company’s principal executive officer, principal financial officer and the next three highest paid executive officers. Prior to the enactment of the Tax Cuts and Jobs Act in December 2017, certain types of compensation to these covered employees were deductible if the requirements of Section 162(m) of the Code with respect to performance-based compensation were satisfied.

For 2018 and subsequent years, covered officers, include the principal executive officer, principal financial officer and next three highest paid executive officers. Compensation paid in 2018 and later years will generally be subject to the $1 million deduction limits of Section 162(m) of the Code, without an exception for performance-based compensation.

The Compensation Committee believes that in establishing incentive compensation programs for our NEOs, the potential deductibility of the compensation payable should be only one of several factors taken into consideration and notconsideration. Therefore, while the sole governing factor. As was the case prior to the enactment of the Tax Cuts and Jobs Act, theCompensation Committee

price or stockholder return, but we believe that pursuing these longer range objectives should result in performance that is more likely to maximize total return to our stockholders over time.

Since our executive compensation is based upon factors relating to our growth and profitability and the performance of our business as well as the contributions of each of our executives to achieving our objectives, we believe that we have provided appropriate incentives to align management’s interests with our long-term growth and development and the interests of our stockholders. We also believe that there are many ways in which our executives contribute to building a successful company. While our financial statements and stock price reflect the results of some of those efforts, many long-term strategic decisions made in pursuing our growth and development may have little visible impact on our stock price in the short term.short-term.
