Who Can Vote

Only stockholders of record at the close of business on March 27, 2017,April 13, 2018, which we refer to as the record date, are entitled to notice of and to attend and vote at the Annual Meeting. As of the record date, there were 34,592,22334,658,733 outstanding shares of our common stock. Each share of our common stock outstanding on the record date will be entitled to cast one vote at the Annual Meeting.

How You Can Vote

Stockholders of record can simplify their voting by voting their shares via telephone or the Internet. Instructions for voting via telephone or the Internet are described on the Notice of Internet Availability of Proxy Materials. Being a record holder means that the shares are registered in your name, as opposed to the name of your broker or bank. If your shares are held in the name of a bank or broker (in “street name”), the availability of telephone and Internet voting will depend on the voting processes of the applicable bank or broker; therefore, it is recommended that you follow the voting instructions on the proxy card. If you request a paper copy of the proxy materials, please mark your choices on the proxy card and then date, sign and return the proxy card at your earliest opportunity pursuant to the instructions on the proxy card.

You may also vote in person at the meeting. If your shares are held in street name, you can vote at the meeting only if you have a valid proxy from your bank or broker confirming your beneficial ownership of shares of our common stock as of the record date and your authority to vote such shares. Please bring personal photo identification with you to the meeting. If you need directions to the Annual Meeting, please call us at (513)(214)458-2600.357-6181.

Revocability of Proxies

Stockholders who execute proxies retain the right to revoke them at any time before the shares are voted by proxy at the meeting. A stockholder may revoke a proxy by delivering a signed statement to our Corporate Secretary at or prior to the Annual Meeting or by timely executing and delivering, by Internet, telephone, mail or in person at the Annual Meeting, another proxy dated as of a later date. Furthermore, you may revoke a proxy by attending the Annual Meeting and voting in person, which will automatically cancel any proxy previously given.

Attendance at the Annual Meeting, however, will not automatically revoke any proxy that you have given previously unless you request a ballot and vote in person. If you hold shares through a bank or brokerage firm, you must contact the bank or brokerage firm to revoke any prior voting instructions.

Quorum Required

In order for business to be conducted, a quorum must be represented at the Annual Meeting. The holders of a majority of the outstanding shares of common stock, present in person or represented by proxy, shall constitute a quorum at the Annual Meeting. Shares represented by a proxy in which authority to vote for any matter considered is “withheld,” a proxy marked “abstain” or a proxy as to which there is a “brokernon-non-vote” vote” (described below) will be considered present at the meeting for purposes of determining a quorum.

- 2 -

Required Vote to Elect Directors

Directors will be elected by a plurality of the votes cast at the Annual Meeting, meaning the nineeight nominees receiving the most votes will be elected. Only votes cast for a nominee will be counted. Unless indicated otherwise by your proxy, the shares will be voted for the nineeight nominees named in this proxy statement. Instructions on the accompanying proxy to withhold authority to vote for one or more of the nominees will result in those nominees receiving fewer votes but will not count as a vote against the nominees.

Required Votes to Pass Other Proposals

Proposal 2 (approval, on an advisory basis, of the Company’s named executive officer compensation) and Proposal 3 (to ratify the selection of BDO USA, LLP as the independent registered public accounting firm of CECO for fiscal year 2017), Proposal 3 (approval, on an advisory basis, of the Company’s named executive officer compensation) and Proposal 4 (approval of the CECO Environmental Corp. 2017 Equity and Incentive Compensation Plan)2018), each requires the favorable vote of the majority of shares represented at the Annual Meeting for approval. Although these votes are advisory in nature and are not binding on the Company, the Board will consider the outcomes of these votes in future deliberations. For these proposals, abstentions are treated as shares present or represented and voting, so abstaining has the same effect as a negative vote.

BrokerNon-Votes

If your shares are held by a bank, broker or other nominee and you do not provide the bank, broker or other nominee with specific voting instructions, the organization that holds your shares may generally vote on “routine” matters but cannot vote onnon-routine matters.

If the bank, broker or other nominee that holds your shares does not receive instructions from you on how to vote your shares on anon-routine matter, the organization will inform our Inspector of Elections that it does not have the authority to vote on this matter with respect to your shares. This is generally referred to as a “brokernon-vote.”

When our Inspector of Elections tabulates the votes for any matter, brokernon-votes will be counted for purposes of determining whether a quorum is present.

We believe that Proposal 2 (ratification of independent auditors) will be considered “routine” and we do not expect any brokernon-votes on this matter.

We believe that Proposal 1 (election of directors), and Proposal 32 (approval, on an advisory basis, of the Company’s named executive officer compensation) and Proposal 4 (approval of the CECO Environmental Corp. 2017 Equity and Incentive Compensation Plan) will be considered“non-routine,” and banks, brokers and certain other nominees that hold your shares in street name will not be able to cast votes on these proposals if you do not provide them with voting instructions. Any brokernon-votes will have the same effect as a vote against Proposal 3 and Proposal 4,2, but will not affect the outcome of Proposal 1 because directors are elected by a plurality of votes cast.

We believe that Proposal 3 (ratification of independent auditors) will be considered “routine” and we do not expect any brokernon-votes on this matter.

Please provide voting instructions to the bank, broker or other nominee that holds your shares by carefully following their instructions.

Other Information

If no instructions are indicated on a duly executed and returned proxy, the shares represented by the proxy will be voted FOR the election of the nineeight nominees for director proposed by the Board and set forth herein, FOR the approval, on an advisory basis, of the Company’s named executive officer compensation and FOR the ratification of the appointment of BDO USA, LLP as the independent registered public accounting firm of the Company for fiscal year 2017, FOR the approval, on an advisory basis, of the Company’s named executive officer compensation, FOR the approval of the CECO Environmental Corp. 2017 Equity and Incentive Compensation Plan2018, and in accordance with the judgment of the persons named in the proxy as to such other matters as may properly come before the Annual Meeting.

PROPOSAL 1

ELECTION OF DIRECTORS

Directors and Nominees

The Board has determined that the number of directors shall be nineeight and, accordingly, the Board has nominated, upon the recommendation of the Nominations and Governance Committee of the Board, the nineeight persons identified below to serve as directors to hold office until the next annual meeting or until their successors shall be duly elected and qualified. The names of, and certain information with respect to, the nominees of the Board for election as directors, are set forth below. The terms of Seth Rudin and Donald A. Wright, who are currently members of the Board, will expire at the Annual Meeting. All nominees are currently CECO directors, except for Mr. Liner.Nanda. Mr. Nanda was identified by the Nominations and Governance Committee as a potential director nominee at the recommendation of several directors, including certain members of the Nominations and Governance Committee, who knew of Mr. Nanda and had met him previously. If, for any reason, any nominee should become unable or unwilling to serve as a director, the Board may either reduce the number of directors to be elected or select a substitute nominee. If a substitute nominee is selected, the persons named in the proxy card may exercise their discretion to vote your shares for the substitute nominee. Mr. Liner was identified as a potential director nominee by the Nominations and Governance Committee on the recommendation of anon-management director.

All of our director nominees and directors who served during 2016,2017, other than Messrs. DeZwirek, Pollack and Sadlowski, (since becoming our interim Chief Executive Officer and President in January 2017), and our former Chief Executive Officer, President and director, Mr. Lang, qualify or qualified, as applicable, as independent directors in accordance with the listing requirements of The NASDAQ Stock Market LLC (the “NASDAQ”). The NASDAQ independence definition includes a series of objective tests, including that the director is not an employee of CECO and has not engaged in various types of business dealings with us. In addition, the Board has made a subjective determination as to each independent director that no relationships exist, which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

The following table shows information as of March 31, 2017April 15, 2018 for each director nominee.

The Board believes that the directors and director nominee as a whole will provide the diversity of experience and skills necessary for a well-functioning Board.

Set forth below is a more complete description of each director’s background, professional experience, qualifications and skills.

All directors attended at least 75% of the aggregate number of meetings of the Board and the Committees on which they served during the fiscal year ended December 31, 2016.2017.

Audit Committee

The Audit Committee held ninefive meetings in 2016.2017.

The primary purpose of the Audit Committee is to assist the Board in its general oversight of CECO’s financial reporting process and approval of the services provided to CECO by its auditors. The Audit Committee also evaluates transactions where the potential for a conflict of interest exists. The Audit Committee’s purposes are more fully described in its written charter, a copy of which can be found on our websitewww.cecoenviro.comon the Investor Relations, Corporate Governance section.

Compensation Committee

Board Leadership Structure and Risk Oversight

The positions of Chairman of the Board and Chief Executive Officer are held by different individuals: Jason DeZwirek serves as Chairman and Dennis Sadlowski serves as interim Chief Executive Officer and President.Officer. Our Bylaws provide that any two or more offices may be held by the same person, but the Board believes that the current separation of the offices of Chief Executive Officer and Chairman reflects the difference in the roles of those positions. The Chief Executive Officer is responsible for determining the strategic direction and theday-to-day leadership of the Company. The Chairman determines the agenda for and presides over Board meetings.

The separation of the roles of Chief Executive Officer and Chairman and the independence of a majority of the board members helps ensure independent oversight of management. All of the directors on the current Board, other than the Chairman, Jason DeZwirek, the interim Chief Executive Officer, and President, Dennis Sadlowski, and Jonathan Pollack qualify as independent under the applicable NASDAQ listing requirements. The standing committees — the Audit Committee, the Compensation Committee and the Nominations and Governance Committee — are comprised entirely of independent directors and provide independent oversight of management.

CECO’s management is responsible for identifying, assessing and managing the material risks facing CECO. The Board performs an important role in the review and oversight of these risks, and generally oversees CECO’s risk management practices and processes, with a strong emphasis on financial controls. The Board has delegated primary oversight of the management of (i) financial and accounting risks and related-party transaction risks to the Audit Committee, (ii) compensation risk to the Compensation Committee and (iii) corporate governance risk to the Nominations and Governance Committee. To the extent that the Audit Committee, Compensation Committee or the Nominations and Governance Committee identifies any material risks or related issues, the risks or issues are addressed with the full Board.

Nomination Process

The Company has a standing Nominations and Governance Committee. The Nominations and Governance Committee identifies individuals qualified to become Board members and makes recommendations to the Board regarding Board and committee composition, consistent with the Director Nomination Policy described below, and develops and recommends Board members to the Board for committee membership.

Director Qualifications and Diversity

Our Board believes that the Board, as a whole, should have a diverse range of characteristics and skills to function at an optimal level in exercising its oversight over the Company. When evaluating a person for nomination for election to the Board, the qualifications and skills considered by the Board, including the Nominations and Governance Committee, include:

The Board applies a broad concept of diversity, which includes all of the criteria listed above together with other factors such as the nominee’s age and leadership abilities. Although CECO does not have a diversity policy, when the Board seeks new director candidates to add to the Board or to replace directors who have resigned or recommends there-election of incumbent directors, the Board selects director nominees on the basis of all of these criteria with the goal of finding the best match for CECO’s Board.

With respect to skill set diversity, the Board seeks to have directors and nominees with not only experience and expertise related to environmental, energy or fluid handling, but also in a broad range of other areas, and the Board currently consists of members with expertise in manufacturing, finance, accounting and legal matters.

Board Composition Changes

We are also undergoing transition in our Board leadership. During 2017, we nominated a new, independent Board member, David Liner, who was elected to the Board at our 2017 annual meeting of shareholders and is the Chairman of our Nominations and Governance Committee. In 2018, the terms of service of two long-term directors (Messrs. Rudin and Wright) will expire at the Annual Meeting. Only one new, independent Board member (Mr. Nanda) has been nominated for election in 2018. Therefore, the Board will be reduced to eight members.

Shareholder Engagement and 2018 Changes to Executive Compensation Program

At our 2017 annual meeting of shareholders, we received approximately 98% approval, based on total votes cast for and against, for our advisory“Say-on-Pay” proposal to approve the compensation of our named executive officers. In 2017, we had direct contact and discussions with shareholders representing greater than 40% of shares outstanding. Our Chairman, CEO, CFO and other directors participated in these discussions and provided shareholder feedback to the Chairs of the Committees of the Board of Directors. Effective January 23, 2017, Mr. Sadlowski, a memberand to the remainder of the Board as a whole. The Compensation Committee considered the 2017Say-on-Pay voting results at its subsequent

meetings and remains dedicated to continuous improvement to the Company’s existing executive pay programs. However, the Compensation Committee did not make any changes to our executive compensation policies or practices that were specifically driven by the outcome of Directors,theSay-on-Pay vote.

Nonetheless, the Compensation Committee did approve changes to our executive compensation programs in 2017 and 2018, as further described below, to be more market competitive and more closely approximate what we believe are industry best practices. Among those changes were the following:

Overview of Compensation Program

The Compensation Committee oversees our compensation programs, with particular attention to the compensation for our Chief Executive OfficerCEO and the other named executive officers (other than for Mr. DeZwirek, our Chairman, who receives his compensation pursuant to the related person transaction arrangement with Icarus as described above). It is the responsibility of the Compensation Committee to review and approve (or, as the case may be, recommend to the Board for approval) changes to our executive compensation policies and benefits programs, to recommend and approve stock-based awards to named executive officers, and to otherwise ensure that the Company’s compensation philosophy is consistent with the best interests of the Company and its stockholders and is properly implemented and monitored. The Compensation Committee reports to the Board on all compensation matters regarding our directors, executives, and other key salaried employees. The Compensation Committee annually reviews and approves the compensation for our directors, executives, and other key salaried employees. The Compensation Committee does not generally delegate any of its authority to other persons, although it has the power to delegate certain authority as permitted by applicable law and the NASDAQ listing standards to subcommittees, the Board or management.

Theday-to-day administration of savings, health, welfare, and paidtime-off plans and policies applicable to salaried employees in general is handled by our human resources and finance department employees. The responsibility for certain fundamental changes outside theday-to-day requirements necessary to maintain these plans and policies belongs to the Compensation Committee.

At our 2016 Annual Meeting, we received approximately 89% approval, based on total votes cast, for our advisory“Say-on-Pay” proposal to approve the compensation of our named executive officers. The Compensation Committee considered the 2016 voting results at its subsequent meetings and remains dedicated to continuous improvement to the existing executive pay programs. As a result of its considerations, the Compensation Committee implemented the executive pay practices described below during the remainder of 2016. In addition, in early 2017 our Board adopted a clawback policy, as further described below.

The following discussion and analysis of our 20162017 executive compensation program, which may include forward-looking statements, should be read together with the compensation tables and related disclosures that follow this section.

Compensation Policy and Objectives

The principal objectives of our executive compensation program are to attract, motivate, retain and reward highly qualified persons who are committed to the achievement as our executive officers of solid financial performance and excellence in the management of the Company’s assets. The Compensation Committee believes that the most effective executive compensation program is one that is designed to reward the achievement of annual, long-term and strategic goals by the Company and to align the named executive officers’ interests with those of the Company’s other stockholders. The Compensation Committee seeks to accomplish this by providing competitive compensation designed to link executive compensation to the Company’s financial and operational performance, as well as rewarding the overall performance of its named executive officers, when applicable, in line with the ultimate objective of increasing stockholder value. The Compensation Committee generally evaluates compensation against individual performance and external market factors to help ensure that we maintain our ability to attract and retain key executive talent. To that end, total compensation for the named executive officers other than our Chairman generally is comprised of a base salary, plus incentive compensation,short-term incentives, and long-term incentives, a portion of which is designed to be earned based on the Company’s financial performance and other factors, including, for certain named executive officers, achievement ofnon-financial, qualitative goals. However, the Compensation Committee retains discretion to approve individual goals. Individualnon-incentive bonuses are also partto reward the individual efforts of overall compensation from time to time based on an individual’s special efforts.named executive officers.

Risk Considerations in our Compensation Program

We structure the compensation of management, other than for our Chairman, to consist of both fixed and variable compensation. The fixed (or salary) portion of compensation is designed to provide a steady income so management does not feel pressured to focus exclusively on short-term gains, which may be to the detriment of long-term stock price appreciation and other business metrics. The variable portions of compensation (cash bonus, short-term incentive and, in some cases, stock, stock-based and option awards) portions of compensation are designed to reward both individual performance and overall corporate performance. For individualIndividual performance cash bonuses areis qualitatively determined by the Compensation Committee. Company performance is determined based on overallachievement in operating income, achievement.bookings and revenue, working capital and (for certain officers) earnings per share, as further described below. We believe that the variable components of compensation are sufficient to motivate management to produce short- and long-term corporate results while the fixed element is also sufficient such that management is not encouraged to take unnecessary or excessive risks in working to produce such results. During 2016, we conducted a risk review of our 2016 compensation program for all employees. Based on this review, we believe our compensation policies and practices do not create risks that are reasonably likely to have a material adverse effect on the Company.

Role of Executive Officers in Compensation Decisions

Based on the compensation objectives described above, the Compensation Committee has generally structured the Company’s annual and long-term incentive-based executive compensation with the intent to motivate the named executive officers other than our Chairman to achieve the business goals set by the Company and to reward them for achieving such goals. These goals have generally included an individual performance goal as well asmay include overall Company performance goals.goals and qualitative goals communicated to the individual named executive officer. The Compensation Committee from time to time relies upon recommendations made by the Company’s management, and in particular, the Chief Executive Officer,CEO, regarding compensation for the named executive officers other than himself and our Chairman. The Compensation Committee reviews and approves (or, if the situation warrants, recommends to the full Board for approval) all new executive compensation programs, including those for the named executive officers other than our Chairman. As part of its review and establishment of the performance criteria and compensation of our named executive officers, the Compensation Committee meets separately at least once on an annual basis with the Chief Executive OfficerCEO and other executives as it deems appropriate. The Chief Executive OfficerCEO and such other executives as the Chief Executive OfficerCEO deems appropriate, including the Chairman, annually review the performance of each of the other named executive officers of the Company, and the Chief Executive Officer’sCEO’s performance is reviewed by the Compensation Committee.Committee and thenon-executive members of the Board of Directors. The conclusions reached and recommendations based on these reviews are presented to the Compensation Committee.Committee and to the non-executive members of the Board of Directors. The Compensation Committee exercises its discretion in modifying any recommended adjustments or awards to named executive officers.

Role of Compensation Consultants in Compensation Decisions

Under its charter, the Compensation Committee has authority to engage such compensation consultants as it deems necessary or appropriate to carry out its responsibilities and to cause the Company to pay the reasonable compensation of such compensation consultants as established by the Compensation Committee.

In 2016,2017, the Compensation Committee engaged Meridian Compensation Partners, LLC (“Meridian”) as its independent executive compensation consultant to assessadvise the Company’s bonus plan design forCompensation Committee on executive officers.compensation matters. At the Compensation Committee’s direction, Meridian prepared, presented and made recommendations on peer group data, competitive market pay, compensation structure, and general market trends. More specifically, Meridian provided the Compensation Committee with market and peer group data to give the Compensation Committee context for the Company’s annual incentive plan participants, target award opportunities and the appropriate allocation between financial and qualitative metrics. In addition, Meridian recommended that the Company set bonusannual incentive targets to align with the Company’s short-term business strategy and complement its long-term incentive structure, as well as beingto be measurable and specific with respect to goals and ranges tied to creating shareholder value. The Compensation Committee considered the advice of Meridian as part of its compensation decision making process for a portion of 20162017 compensation, as further described below.

As noted above, the Company engaged Mr. Sadlowski to serve as interim CEO in January 2017. After a thorough internal and external search, and based on his successful tenure as interim CEO, the Company determined that Mr. Sadlowski was best positioned to take on the role of permanent CEO. In connection with Mr. Sadlowski’s appointment, Meridian advised the Compensation Committee on the design of Mr. Sadlowski’s compensation package, including the elements and magnitude of pay.

The Compensation Committee has assessed the independence of Meridian, as required under the NASDAQ listing requirements. The Compensation Committee also has considered and assessed all relevant factors, including those set forth in Rule10C-1(b)(4)(i) through (vi) under the Exchange Act, that could give rise to a potential conflict of interest with respect to Meridian during 2016.2017. Based on this review, the Compensation Committee did not identify any conflict of interest raised by the work of Meridian. Meridian does not provide any services to management or any other services to the Company.

Setting Executive Compensation

The Compensation Committee evaluates the performance of the Chief Executive OfficerCEO and the other named executive officers (other than our Chairman) and, based on such evaluation, reviews and approves the annual salary, annual cash incentive, bonus, long-term stock-based compensation, and other material benefits of the Chief Executive OfficerCEO and such other named executive officers, subject to the terms of any applicable employment agreements. In determining appropriate base salary levels, subjective consideration is given to the applicable named executive officer’s impact level, scope of responsibility and past accomplishments and other similar factors.accomplishments.

External Pay Comparisons

The Compensation Committee used external pay comparison data as a market check on its compensation decisions, but not for specific benchmarking. In 2016,2015, Meridian prepared a list of peer companies with input from members of the Board and Mr. Lang. The composition of theBoard. This peer group was intended to place the Company at roughly median levels in terms of size based primarily on revenue and market capitalization andinitially designed to include companies with which we compete for executive talent. The market check peer group was determined to be appropriate again for 20162017 and consisted of the following 21 companies:

The market check peer group for 20162017 was generally the same as the market check peer group for 2015, except that PMFG, Inc., which we acquired2016 and 2015. Currently, the Company is in September 2015, was removed.the bottom quartile of the peer group in terms of size, based primarily on revenue and market capitalization.

Based on its review of the peer group data and market data and other factors outlined in the Compensation Discussion and Analysis, among other things, Meridian determined that Mr. Sadlowski’s 2018 total target compensation approximates the overall bonus targets for Mr. Lang were not aligned with25^th percentile of the peer group, median. Accordingly,which is in line with where the Compensation Committeere-aligned Mr. Lang’s bonus targets to generally align with CECO’s short-term business strategy and complementCompany is positioned within the long-term incentive structure,peer group, as well as making such bonus targets measurable and specific to goals and ranges, tied to creating shareholder value.described above.

Chief Executive Officer Stock Ownership Guidelines

Effective August 3, 2016, the Board implemented mandatory stock ownership guidelines for our Chief Executive OfficerCEO to further align the interests of the Chief Executive OfficerCEO and stockholders. The Chief Executive OfficerCEO is required to own shares of our common stock having a value equal to at least five times his or her base salary. The Chief Executive Officer shall haveOn March 30, 2018, the Compensation Committee approved revised stock ownership guidelines, which require the Company’s named executive officers to own shares of our common stock having values equal to the applicable multiple of base salary set forth in the table below:

A named executive officer has five years from his or her appointment as Chief Executive Officerto a participating position to comply with this requirement. The Compensation Committee in its discretion may extend the period of time for attainment of such ownership levels in appropriate circumstances. For purposes of this requirement, the Chief Executive Officer’s stock ownership includes all shares of our common stock owned by the Chief Executive Officernamed executive officer outright or held in trust for the Chief Executive OfficerCEO and his or her immediate family, plus the Chief Executive Officer’sCEO’s deferred or restricted stock or equivalentrestricted stock units. The value of a share shall beis measured as the greater of the then current market price or the closing price of a share of the common stock on the grant date.

Elements of Compensation

Base Salary

The Company provides named executive officers (other than our Chairman) with a base salary to compensate them for the expertise and value they bring to their jobs. Base salary is determined for each applicable named executive officer based on his position and responsibility by taking into account the named executive officer’s impact level, external market data, scope of responsibility, prior experience, past accomplishments and other similar factors, and the particular base salary is subject to any existing employment agreement with such named executive officer.

- 17 -

Salary levels offor the applicable named executive officers are reviewed and approved by the Compensation Committee annually as well as upon a promotion or other change in job responsibility. The salary levels, including any increases, are also based on the Compensation Committee’s evaluation of the individual’s strengths, development and expected future contributions with respect to the corporate goals and objectives relevant to the individual’s compensation, including individual performance. OurBase salary rates in effect during employment for the named executive officers’officers during 2017 were as follows:

None of the named executive officers who were employees in 2016 received a salary increase in 2017, except for Mr. Gohr, whose base salary shown in the table above reflects an increase of $37,635 per year (or approximately 25% of his base salary) on May 16, 2017 in connection with his promotion to Chief Accounting Officer. The base salaries of Messrs. Eckl and Sadlowski were unchanged from 2015determined based on the factors outlined above and impacted by arms’ length negotiations with such officers in 2016.connection with their commencement of employment during 2017.

Cash Incentive Compensation

Mr. Lang was entitled, under his employment agreement, to a cash bonus targeted at 100% of his base salary. The payout could vary depending on the extent to which performance objectives, as approved by the Compensation Committee, were met, ranging from 50% of the target payout in the event that a threshold aggregate performance level of 80% was achieved, to 120% of the target payout in the event that the maximum aggregate performance level of 110% was achieved. For 2016, the Compensation Committee established multiple objectives for Mr. Lang’s annual incentive opportunity. The objectives were both quantitative (weighted at 80%) and qualitative (weighted 20%). The target quantitative goals, each of which was weighted at 20%, consisted of achieving (1) earnings before interest, taxes, depreciation and amortization (“EBITDA”) of $59.3 million, (2) revenue of $452.3 million,(3) non-GAAP earnings per diluted share (“EPS”) of $0.94 and (4) working capital at 16% of 2016 revenue. The qualitative objectives consisted of continuing efforts in furthering the Company’s succession planning and updating the Company’s strategic plan.

Actual achievement for 2016 with respect to the quantitative objectives was as follows:

After consideration of the degree of achievement of the quantitative and qualitative objectives, and in connection with Mr. Lang’s entry into the Separation Agreement described below inEmployment and Separation Agreements, the Compensation Committee awarded a bonus to Mr. Lang of $575,000, which was 100% of his then-current base salary.

In addition, weWe believe that a portion of the compensation paid to our other named executive officers (other than the Chairman) should be designed to be earned based on our annual performance, so that the executives are appropriately motivated to maximize our operating performance each year. To that end, in 2017 the Compensation Committee and the Board approved and adopted an Amended and Restated 2006 Executive Incentive Compensation Plan (the “Bonus Plan”).annual incentive award opportunities for our named executive officers under our annual incentive program. Under the Bonus Plan,annual incentive program, the Compensation Committee selects the executive officers to participate in the Bonus Plan,annual incentive program, determines the amounts of awards for each such executive officer, determines the performance goals, and determines whether objectives and conditions for earning awards have been met. The performance goals may consist of both objective financial targets and (for certain named executive officers) personal qualitativeperformance targets.

The Compensation Committee selected theEach of our participating named executive officers to participate inhad a target cash incentive opportunity for 2017 expressed as a percentage of base salary. In 2017, following consultation with Meridian, the Bonus Plan, determined performance goals for fiscal year 2016, and determined whether objectives and conditions for earning awards were met. For 2016,Company proposed, the Compensation Committee selectedrecommended, and the Board approved, a modification to the annual incentive compensation program to expand the range of payouts for above target performance for certain named executive officers, including by increasing the maximum payout for the CEO and the CFO to 200%. Previously, the CEO and CFO were eligible for a payout of up to 120% of their annual incentive target. Mr. Prajzner and Mr. Cook to participateLang was not a participant in the Bonus Plan. There2017 cash incentive program as he was no longer employed by the Company at the time performance targets were two componentsset. Mr. DeZwirek was not a participant in the 2017 cash incentive program, as he receives his compensation pursuant to the related person transaction arrangement with Icarus, as described above. Target awards and potential payout levels for the participating named executive officers for 2017 are shown in the following table:

For 2017, in recognition of his promotion to Chief Accounting Officer and his increased responsibilities, Mr. Gohr’s target award was increased from 25% of base salary (which was the applicable target level for his 2016 annual incentive) to 35% of base salary.

Depending on the performance results achieved, actual awards can vary as a percentage of target from a threshold of 50% to a maximum level, as set forth in the table above. For 2017, the Compensation Committee approved the specific performance measures for the 2017 cash incentive program and their relative weightings. If the designated target level for each performance metric is attained, the cash incentive award is designed to pay out at 100% for that metric. The threshold is the lowest level of payout below which no payment is made for the specific component. If performance for a metric is between the identified threshold and target, or target and maximum, the actual payout is determined based on straight-line mathematical interpolation. However, regardless of the actual attainment of any of the individual metrics, the awards were designed so that no payout was to occur if we did not achieve a threshold operating income goal of $46,400,000 for the performance period.

The following performance metrics were selected for the 2017 cash incentive program to drive desired behavior that impacts shareholder value:

To the extent earned, the performance units generally vest over a four-yearon the third anniversary of the grant date. If, upon the conclusion of the performance period, our stock price performance is between performance levels, there will be no interpolation between payout levels.

Personal Benefits and Perquisites

The Company provides certain named executive officers with perquisites and other personal benefits that the Company and the Compensation Committee believe are reasonable and consistent with the Company’s overall compensation program to better enable the Company to attract and retain employees for key positions. These perquisites consist of car allowances and payment of life insurance premiums, as applicable, as further described in the 20162017 Summary Compensation Table below.

Retirement and Post-Employment Benefits

The Company sponsors a 401(k) retirement plan for our employees (the “401(k) Plan”). Pursuant to the 401(k) Plan, the Company matches contributions each pay period at 100% of the employee’s contributions for the first 3%, and 50% on the next 3%, of an employee’s compensation for a maximum match of 4.5%. The named executive officers (other than our Chairman) may participate in the 401(k) Plan on the same terms as the rest of our employees. We believe the 401(k) Plan is set at a reasonable level, is highly valued by recipients, has limited cost, is part of a competitive compensation program and is consistent with our overall goal of attracting and retaining qualified employees.

For more information about our Incentive Plan andequity compensation awards under that plan for 2016,2017, see the 20162017 Grants of Plan-Based Awards Table and theOutstanding Equity Awards at 20162017 FiscalYear-End Table and the accompanying narratives below.

Agreements with Individual Named Executive Officers

We entered into an employment agreement with Mr. Eckl effective as of January 9, 2017. We entered into an interim offer letter with Mr. Sadlowski on January 26, 2017, and then entered into an employment agreement with Mr. Sadlowski on June 10, 2017 when he was appointed as permanent CEO. These employment agreements and offer letters, as applicable, set forth the basic terms and conditions of employment for such named executive officers, including initial base salary, annual incentive opportunity, and long-term incentive opportunity, as well as certainsign-on equity and cash bonus compensation and certain perquisites and personal benefits. The employment agreements also include customary restrictive covenants and provide for certain severance compensation and benefits in the event of a qualifying termination of employment. The terms of these employment agreements reflect the product of arms’ length negotiations between the named executive officers and the Company.

At the beginning of 2017, we were party to an employment agreement with Mr. Lang. However, in connection with Mr. Lang’s separation from the Company, on February 1, 2017 we entered into a Separation Agreement with Mr. Lang pursuant to which the Company provided him certain severance compensation and benefits. In connection with his separation from the Company on July 21, 2017, Mr. Prajzner entered into a separation agreement and release with the Company, pursuant to which the Company provided him certain severance compensation and benefits.

For more information regarding these individual arrangements and the benefits provided thereunder, please see Potential Payments Upon Termination or Change of Control below.

Clawback Policy

In April 2017, our Board adopted a clawback policy. Under the clawback policy, if (1) the Company is required to prepare an accounting restatement due to the Company’s material noncompliance with any financial reporting requirement under the U.S. federal securities laws and (2) the Board reasonably in good faith determines that any current or former “Section 16 officer” of the Company willfully committed an act of fraud, dishonesty or recklessness that contributed to the noncompliance or benefitted materially from excessive incentive-based compensation, then the Board may direct the Company to use prompt and reasonable efforts to recover the excessive incentive-based compensation.

2018 Compensation Decisions

As noted above, for 2018, the Compensation Committee has approved certain changes to the Company’s executive compensation practices. Generally these changes were approved, with the advice of Meridian, to be more market competitive and more closely approximate what we believe are industry best practices.

- 20 -Under the annual incentive program for 2018, payouts for Messrs. Sadlowski and Eckl will range from 0% of target to a maximum level of 200% of target. However, for all other eligible named executive officers, payouts can range from 0% of target to a maximum level of 150% of target. The performance metrics applicable to 2018 annual incentive awards are revenue, adjusted operating income and adjusted free cash flow. We believe these metrics help inspire and drive desired behaviors and performance. We expect to describe the actual goals associated with these metrics in next year’s proxy statement.

The Compensation Committee also approved a change to the Company’s long-term incentive program for 2018. In particular, stock options will not be granted during 2018 to our named executive officers. Instead, long-term incentive awards will generally consist of time-based RSUs and performance-based RSUs. For Mr. Sadlowski, 70% of the target long-term incentive award value will be allocated to performance-based RSUs, and the remaining 30% will be allocated to time-based RSUs. For Mr. Eckl, the target long-term incentive award value will be allocated evenly between time-based and performance-based RSUs. For Mr. Gohr, 30% of such value will be allocated to performance-based RSUs, and the remaining 70% will be allocated to time-based RSUs. Performance-based RSUs will be subject to an EBITDA metric. This design is intended to help align named executive officer rewards with shareholder interests, and to help create a stronger and more direct connection to success drivers and stock price performance.
