SUMMARY OF THE ANNUAL MEETING

This proxy statement contains information related to our 2018 Annual Meeting of Stockholders (the “Annual Meeting”) of Global Brass and Copper Holdings, Inc. (referred to herein as the “Company,” “GBC,” “we,” “us” or “our,” as the context requires) to be held at The Woodfield Corporate Center, 425 N. Martingale Road, Suite 90, Schaumburg, Illinois 60173, on May 24, 2018, at 10:00 a.m. (Central Time). This proxy statement is first being distributed to stockholders on or about April 12, 2018.

Why did you send me this proxy statement?

We sent you this proxy statement because the Board of Directors (the “Board”) of the Company is soliciting your proxy to vote at the Annual Meeting to be held on May 24, 2018, at 10:00 a.m. (Central Time) and at any postponements or adjournments of the Annual Meeting. This proxy statement summarizes information that is intended to assist you in making an informed vote on the proposals described in this proxy statement.

Who can vote at the Annual Meeting?

Only stockholders of record, as of the record date, are entitled to vote at the Annual Meeting. The record date to determine stockholders entitled to notice of and to vote at the Annual Meeting is the close of business on March 26, 2018. On the record date, there were 22,159,380 shares of our common stock, par value $0.01 per share, outstanding. Our common stock is the only class of voting securities outstanding.

How many shares must be present to conduct the Annual Meeting?

We must have a quorum present in person or by proxy to conduct the Annual Meeting. A quorum is established when a majority of shares entitled to vote is present in person or represented by proxy at the Annual Meeting. Abstentions and broker non-votes (as described below) are counted for purposes of determining whether a quorum is present.

What matters are to be voted on at the Annual Meeting?

The agenda for the Annual Meeting is to:

1. elect seven (7) directors;

2. ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2018;

3. to approve, on an advisory basis, the compensation of the Company’s named executive officers; and

4. conduct any other business properly brought before the meeting or any adjournments or postponements thereof.

As of the date of this proxy statement, we do not know of any other matters to be presented at the Annual Meeting. However, if any other matters properly come before the Annual Meeting, the persons named in your proxy will be authorized to vote or otherwise act in accordance with their judgment.

How does the Board recommend that I vote?

The Board recommends that you vote:

1. FOR the election of each of the Company’s director nominees named in this proxy statement;

2. FOR the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2018; and

3. FOR the approval, on an advisory basis, of the compensation of the Company’s named executive officers.

1

How do I vote at the Annual Meeting?

You may vote in person at the Annual Meeting or by proxy. There are three ways to vote by proxy:

• By Telephone-You can vote by telephone by following the instructions on your proxy card. You will need to use the control number appearing on your Notice or proxy card to vote by telephone;

• By Internet-You can vote via the Internet by following the instructions on your proxy card. You will need to use the control number appearing on your Notice or proxy card to vote via the internet; or

• By Mail-You can vote by completing, dating, signing and returning the proxy card in the enclosed postage-paid envelope.

Telephone and Internet voting facilities for stockholders of record will be available 24 hours a day. You may vote over the telephone or via the Internet until 10:59 p.m. (Central Time) on May 23, 2018. Even if you plan to attend the Annual Meeting in person, we recommend that you also submit your proxy or voting instructions as described above so that your vote will be counted if you later decide not to attend the Annual Meeting in person.

Your proxy will be voted in accordance with your instructions, so long as, in the case of a proxy card returned by mail, such card has been signed and dated. If you vote your shares via the Internet, by telephone or by executing and returning a proxy card by mail but you do not provide specific instructions with respect to the proposals, your shares will be voted FOR the director nominees named in this proxy statement, FOR the ratification of the appointment of our independent registered public accounting firm, and FOR the advisory approval of the compensation of our named executive officers, as described in this proxy statement.

As of the date of this proxy statement, we do not know of any other matters to be presented at the Annual Meeting except those described in this proxy statement. If any other matters properly come before the Annual Meeting, however, the persons named in the enclosed proxy will be authorized to vote or otherwise act in accordance with their judgment.

What should I do if I receive more than one set of proxy materials from the Company?

If you hold your shares in multiple accounts or registrations, or in both registered and street name, you may receive proxy materials for each account. Please vote by telephone or via the Internet for each Notice and set of proxy materials that you receive, or vote by mail by signing, dating and returning all proxy cards you receive from the Company. Only the latest dated proxy that you submit for each account will be voted and counted.

May I change my vote?

Yes. You may revoke your proxy at any time before it is voted at the Annual Meeting. To change your vote, if you are a stockholder of record, you may submit another later dated proxy by telephone, Internet or mail or by voting your shares in person at the Annual Meeting (your attendance at the Annual Meeting will not, by itself, revoke your proxy; you must vote in person at the Annual Meeting to revoke your proxy). If you are a beneficial owner and your shares are held in street name, you may change your vote by submitting new voting instructions to your bank, broker, trustee or nominee, or if you have obtained a legal proxy from such entity giving you the right to vote your shares, you may change your vote by attending the Annual Meeting and voting in person.

What vote is required to elect directors and approve the other matters described in this proxy statement?

Consistent with good governance policies, the Company’s amended and restated bylaws (“Bylaws”) provide for majority voting in uncontested elections. Because this is an uncontested election, the director nominees must receive the affirmative vote of a majority of the votes cast to be elected (i.e., the number of shares voted “for” a director nominee must exceed the number of votes cast “against” that nominee) (Proposal No. 1). Abstentions and broker non-votes will have no effect on the outcome of the election of directors.

For the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm (Proposal No. 2) and the approval, on an advisory basis, of the compensation of the Company’s named executive officers (Proposal No. 3), the affirmative vote of the holders of a majority of the shares represented in person or by proxy and entitled to vote on the proposal will be required for approval. Abstentions will not be voted but will be counted for purposes of determining whether there is a quorum. Accordingly, abstentions will have the effect of a negative vote on Proposals No. 2 and 3. Broker non-votes will have no effect on Proposal No. 3.

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

If your shares are registered in your name on the Company’s books and records or with our transfer agent, you are the “stockholder of record” of those shares, and this proxy statement and accompanying materials have been provided directly to you by the Company.

2

On the other hand, if you purchased your shares through a brokerage or other financial intermediary, the brokerage or other financial intermediary will automatically put your shares into “street name” which means that the brokerage or other financial intermediary will hold your shares in its name or another nominee’s name and not in your name, but will keep records showing you as the “beneficial owner.” If you hold shares beneficially in street name, this proxy statement and accompanying materials have been forwarded to you by your broker, bank or other holder of record.

How do I vote if my bank or broker holds my shares in “street name”?

If you hold your shares in “street name” through a bank, broker or other nominee, such bank, broker or nominee will vote those shares in accordance with your instructions. To so instruct your bank, broker or nominee, you should refer to the information provided to you by such entity. Without instructions from you, a bank, broker or nominee will be permitted to exercise its own voting discretion with respect to so-called routine matters but will not be permitted to exercise voting discretion with respect to non-routine matters. The only routine matter on our agenda for the Annual Meeting is Proposal No. 2 (ratification of auditors). Proposals No. 1 (director elections) and 3 (advisory vote on the compensation of our named executive officers) are each non-routine matters. Thus, if you do not give your bank, broker or nominee specific instructions with respect to Proposal No. 2, your shares will be voted in such entity’s discretion. If you do not give your bank, broker or nominee specific instructions with respect to the remaining proposals, your shares will not be voted on such proposals. This is called a “broker non-vote.” Shares represented by such broker non-votes will be counted in determining whether there is a quorum and will have the effect described above on each of the non-routine proposals. We urge you to provide your bank, broker or nominee with appropriate voting instructions so that all your shares may be voted at the Annual Meeting.

How many votes do I have?

Each share of common stock that you hold as of the record date entitles you to one vote, without cumulation, on each matter to be voted upon at the Annual Meeting.

How will the votes be counted at the Annual Meeting?

The votes will be counted by the inspector of elections appointed for the Annual Meeting.

How will the Company announce the voting results?

The Company will report the final results of the voting at the Annual Meeting in a filing with the SEC on a Current Report on Form 8-K.

Who pays for the Company’s solicitation of proxies?

The Board is soliciting your proxy to vote your shares of common stock at our Annual Meeting. We will bear the cost of soliciting proxies on behalf of the Company, including preparing, printing and mailing this proxy statement. Proxies may be solicited personally, by mail, email or by telephone by certain of our directors, officers, employees or representatives. Our directors and employees will not be paid any additional compensation for soliciting proxies. We will reimburse brokerage houses, banks, custodians, and other nominees and fiduciaries for out-of-pocket expenses incurred in forwarding our proxy solicitation materials.

What is “householding” and how does it work?

Under the rules adopted by the SEC, we may deliver a single set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as “householding” and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials, as requested, to any stockholder at the shared address to which a single copy of these documents was delivered. If you prefer to receive separate copies of the proxy statement or annual report, contact Broadridge Financial Solutions, Inc. by calling 1-866-540-7095 or in writing at 51 Mercedes Way, Edgewood, New York 11717, Attention: Householding Department.

In addition, if you currently are a stockholder who shares an address with another stockholder and would like to receive only one copy of future notices and proxy materials for your household, you may notify your broker if your shares are held in a brokerage account or you may notify us if you hold registered shares. Registered stockholders may notify us by contacting Broadridge Financial Solutions, Inc. at the above telephone number or address.

What do I need for admission to the Annual Meeting?

Attendance at the Annual Meeting or any adjournment or postponement thereof will be limited to record and beneficial stockholders as of the record date (March 26, 2018), individuals holding a valid proxy from a record holder, and other persons authorized by the Company. If you are a stockholder of record, your name will be verified against the list of stockholders of record prior to your admittance to the Annual Meeting or any adjournment or postponement thereof. You should be prepared to present photo identification for admission. If you hold your shares in a street name, you will need to provide proof of beneficial ownership on the record date, such as a brokerage account statement showing that you owned stock as of the record date, a copy of a voting instruction form provided by your broker, bank or other nominee, or other similar evidence of ownership as of the record date, as well as your photo identification, for admission. If you do not provide photo identification or comply with the other procedures described above, you will not be admitted to the Annual Meeting or any adjournment or postponement thereof. For security reasons, you and your bags may be subject to search prior to your admittance to the Annual Meeting.

Criteria for Selection of Directors

In accordance with our Corporate Governance Guidelines, the Nominating and Governance Committee is responsible for identifying, screening and recommending to the entire Board candidates for Board membership. The Nominating and Governance Committee is responsible for reviewing the qualifications and independence of the members of the Board and its various committees on a periodic basis as well as the Board’s composition as a whole. This assessment will include members’ independence, as well as consideration of diversity, age, skills and experience in the context of the needs of the Board. The following are general criteria that the Nominating and Governance Committee could use in evaluating candidates for Board membership. None of the following should be construed as minimum qualifications for director selection:

• background, experiences and record of achievement, including, without limitation, in the manufacturing and raw materials industries;

• diversity with respect to viewpoints, background, experience, skill, education, national origin, gender, race, age, culture and current affiliations;

• personal and professional ethics and integrity, collegiality, objective perspective and practical judgment;

• ability and willingness to devote sufficient time to carry out duties and responsibilities effectively;

• commitment to maximizing intrinsic stockholder value; and

• finance and accounting expertise.

Our Corporate Governance Guidelines provide guidelines with respect to the consideration of director candidates. Based on these guidelines, the Nominating and Governance Committee will review annually the relationships that each director has with the Company either directly or as a partner, member, stockholder, director or officer of an entity or organization that has a relationship with the Company. The Nominating and Governance Committee will review with the Board, on a periodic basis, the skills and characteristics required of the Board members in the context of the current director candidates in accordance with its charter. The Board itself will be ultimately responsible for selecting its own members and nominating them for election by stockholders.

The Nominating and Governance Committee will consider director candidates who are proposed by the Company’s stockholders in accordance with the Bylaws, the Nominating and Governance Guidelines and any other policies and procedures established from time to time by the Nominating and Governance Committee.

Recommendation of Directors by Stockholders

In accordance with the Corporate Governance Guidelines, the Nominating and Governance Committee will consider candidates for election as a director of the Company recommended by any stockholder, provided that the recommending stockholder follows the procedures set forth in Section 3.3 of the Bylaws for nominations by stockholders of persons to serve as directors. The Nominating and Governance Committee would evaluate such candidates in the same manner by which it evaluates other director candidates considered by the Nominating and Governance Committee, as described above.

Pursuant to Section 3.3 of the Bylaws, all nominations of stockholder nominees must be made by timely written notice given by a stockholder of record of the Company. To be timely, the notice must be delivered personally or mailed to and received at the Company’s office, addressed to the attention of the Corporate Secretary. In the case of the nomination at an annual meeting of stockholders, no earlier than 120 days and no later than 90 days before the first anniversary of the date of the prior year’s annual

9

meeting of stockholders; provided, however, that if the annual meeting of stockholders is more than 30 days earlier or 60 days later than the first anniversary of the prior year’s annual meeting of stockholders, no annual meeting was held during the prior year, the notice by the stockholder must be received no earlier than 120 days before such annual meeting and no later than the later of 90 days before such annual meeting or the tenth day after the day on which the notice of such annual meeting was made by mail or was otherwise publicly disclosed.

The stockholder’s notice or recommendation is required to contain certain prescribed information about each person whom the stockholder proposes to recommend for election as a director, the stockholder giving notice and the beneficial owner, if any, on whose behalf notice is given. The stockholder’s notice must also include the consent of the person proposed to be nominated and to serve as a director if elected. Recommendations or notices relating to director nominations should be sent to Global Brass and Copper Holdings, Inc., 475 N. Martingale Road Suite 1050, Schaumburg, Illinois 60173; Attention: Anne-Marie W. D’Angelo, General Counsel and Corporate Secretary.

A copy of our Bylaws, has been filed as an exhibit to our Form 8-K filed on March 10, 2015.

Independence of Directors

Our common stock is listed on the New York Stock Exchange (the “NYSE”). The NYSE rules require that a majority of the members of our Board and each of the members of our Compensation and Nominating and Governance Committees be independent. As of the date of this proxy statement, we have satisfied such NYSE requirements.

The Board has determined that Ms. Avril and Messrs. Marsh, Ray, Walker, Welch and Whitaker are “independent directors” as such term is defined by the applicable rules and regulations of the NYSE. Mr. Wasz does not qualify as an independent director, for purposes of the NYSE, because he is our current Chief Executive Officer and President.

Board’s Role in Risk Oversight

The Board has an oversight role, as a whole and also at the committee level, in overseeing management of our risks. Our Board focuses on our general risk management strategy, the most significant risks facing us, and oversees the implementation of risk mitigation strategies by management. The Board regularly reviews information regarding our credit, liquidity and operations, as well as the risks associated with each. The Compensation Committee of the Board is responsible for overseeing the management of risks relating to our employee compensation plans, policies and programs, as well as our annual report on executive compensation for inclusion in each proxy statement and the Audit Committee of the Board oversees the management of financial risks. The Nominating and Governance Committee of the Board is responsible for overseeing the management of risks relating to corporate governance matters. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks.

Corporate Governance

The Board has approved Corporate Governance Guidelines and a Code of Conduct and Ethics. All of our corporate governance documents, including the Corporate Governance Guidelines, the Code of Business Conduct and Ethics and committee charters, are available on our website at www.gbcholdings.com or in printed form upon request by contacting Global Brass and Copper Holdings, Inc. at 475 N. Martingale Road Suite 1050, Schaumburg, Illinois 60173, Attention: Investor Relations. The Board regularly reviews corporate governance developments and will modify these documents as warranted. Any modifications will be reflected on our website. The information on our website is not part of this proxy statement and is not deemed to be incorporated by reference herein.

Other Board Information

Leadership Structure of the Board

The Board has determined that the appropriate leadership structure for the Board at this time is for Mr. Walker, our former Chief Executive Officer, to serve as Chairman of the Board. Prior to February 2017, Mr. Walker served as the Non-Executive Chairman of the Board and Mr. Whitaker served as the lead independent director-a separate, independent, non-management director that provided independent leadership. In February 2017, the Board determined that Mr. Walker was an independent director, which eliminated the need for a separate lead independent director. Mr. Walker possesses detailed and in-depth knowledge of the issues, opportunities, and challenges facing the Company and its businesses and is thus best positioned to develop agendas that ensure that the Board’s time and attention are focused on the most critical matters. We believe that this structure is appropriate for the Company because it allows our Chairman to lead the Board in its fundamental role of managing the Company and providing advice to management, while also providing for effective oversight by a majority of independent directors and allowing our Chief Executive Officer and President to focus on the execution of our business strategy, growth and development.

10

We do not have a formal policy that requires the positions of Chairman and Chief Executive Officer to be separate, and the Board, in its discretion, may subsequently decide to change the leadership structure. Currently, the Chairman of our Board is our former Chief Executive Officer and the Board has determined that a lead independent director is not necessary at this time.

Lead Independent Director

In the future, the Company may choose to appoint a lead independent director to coordinate the activities of the other non-management directors, and to perform such other duties and responsibilities as the Board may from time to time determine. Through February 2017, Ronald C. Whitaker served as our lead independent director, and after such time, the role of the lead independent director concluded with the determination that Mr. Walker, the Chairman of the Board, was independent.

While serving as lead independent director, Mr. Whitaker has followed governance practices established by the Board that support effective communication and effective Board performance.

Board Meetings

In 2017, our Board held ten (10) meetings. In addition to our Board meetings, our directors attend meetings of committees established by our Board. Each of our director nominees attended at least 75% of the meetings of our Board and the committees on which he or she served during 2017 that were held when he or she was a director. Our directors are encouraged to attend all annual and special meetings of our stockholders. In 2017, all seven (7) directors attended the annual meeting of stockholders. Through February 2017, Mr. Whitaker presided over non-management sessions, and after February 2017, Mr. Walker has presided over non-management sessions.

Committees of the Board

The Board has four standing committees: the Audit Committee, the Compensation Committee, the Executive Committee, and the Nominating and Governance Committee. The following chart sets forth the directors who currently serve as members of each of the Board committees.

Audit Committee

In 2017, the Audit Committee held seven (7) meetings. Each of the members of the Audit Committee is a non-employee director. In addition, the Board has determined that all of the members of the Audit Committee are independent as defined in the listing standards of the NYSE and under Rule 10A-3 of the Exchange Act and that all such members are financially literate. The Board also has determined that all members of the Audit Committee are audit committee financial experts, as defined in Item 407(d) of Regulation S-K under the Exchange Act and have accounting or related financial management expertise. Our Corporate Governance Guidelines limit the number of public company audit committees on which an Audit Committee member can serve to three or fewer audit committees (including the Company’s Audit Committee) without approval of the Board. None of our Audit Committee members serve on more than three public company audit committees (including the Company’s Audit Committee).

11

The principal duties and responsibilities of our audit committee are to prepare the report required by the rules of the SEC to be included in our annual proxy statement or annual report and oversee and monitor the following:

• the integrity of our financial statements;

• the independence, qualifications and performance of our independent registered public accounting firm;

• compliance by our personnel with our code of ethics and related-person transactions policies;

• the performance of our internal audit function; and

• compliance by us with legal and regulatory requirements.

For a further discussion of the Audit Committee’s responsibilities and findings, see “Audit Committee Report.” The Audit Committee operates under a written charter setting forth its functions and responsibilities. A copy of the current charter is available on our website at www.gbcholdings.com or in printed form upon request.

Compensation Committee

In 2017, the Compensation Committee held six (6) meetings. Each of the current members of the Compensation Committee is a non-employee director. In addition, the Board has determined that all of the members of the Compensation Committee are independent as defined (i) in the listing standards of the NYSE, including the specific independence requirements for compensation committee members and (ii) the Company’s corporate governance guidelines. Additionally, the Board has determined that all of the members of the Compensation Committee are outside directors for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”).

The principal duties and responsibilities of the Compensation Committee are as follows:

• developing, reviewing, evaluating and monitoring our overall compensation policies, including, without limitation, determining the appropriate balance among base salary, annual bonus and long-term incentive awards, and establishing performance based incentives that support and reinforce (i) our objectives and performance goals and (ii) the long-term interests of our stockholders;

• annually reviewing and approving corporate goals and objectives relevant to our Chief Executive Officer’s compensation, evaluating our Chief Executive Officer’s performance in light of these goals and objectives, and determining and approving our Chief Executive Officer’s compensation level based on such evaluation;

• reviewing and approving the annual base salaries and annual incentive opportunities of our senior executives;

• reviewing and approving employment agreements, severance arrangements, change-in-control agreements, including any change-in-control provisions affecting any elements of compensation and benefits, all other incentive awards and opportunities, including both cash-based and equity-based awards and opportunities, any special or supplemental compensation and benefits for our current and former senior executives, including supplemental retirement benefits and the perquisites provided to them during and after employment;

• administering our incentive compensation plans and equity-based compensation plans and making recommendations to the Board with respect to those plans;

• reviewing our Compensation Discussion and Analysis and other reports and disclosures to be included in our various public filings and making recommendations to the Board with respect to those disclosures;

• reviewing our employee compensation programs as they relate to risk management and risk-taking incentives;

• reviewing and recommending to the Board for approval the compensation of directors for their services to the Board;

• overseeing compliance with NYSE rules with respect to our stockholders’ approval of our equity compensation plans; and

• providing regular reports to the Board and any Compensation Committee reports required by the SEC to be included in our proxy statement and annual report.

The Compensation Committee has engaged Willis Towers Watson (“WTW”) as its independent compensation consultant. WTW reports directly to the Compensation Committee and assists in the review and design of our executive compensation program. The Compensation Committee has reviewed and confirmed the independence of WTW and concluded that their work for the Compensation Committee does not raise any conflict of interest.

12

The Compensation Committee may form and delegate authority to subcommittees, including committees whose members are not members of the Board, as it deems appropriate.

No subject employee should attend that portion of any meeting where the subject employee's performance or compensation is discussed, unless specifically invited by the Compensation Committee. Meetings to determine the compensation of our Chief Executive Officer must be held in executive session. Meetings to determine the compensation of subject employees other than our Chief Executive Officer may be attended by our Chief Executive Officer, but our Chief Executive Officer may not vote on these matters.

The Compensation Committee operates under a written charter setting forth its functions and responsibilities. A copy of the current charter is available on our website at www.gbcholdings.com or in printed form upon request.

Nominating and Governance Committee

In 2017, the Nominating and Governance Committee held four (4) meetings. Each of the current members of our Nominating and Governance Committee is a non-employee director. In addition, the Board has determined that all of the current members of the Nominating and Governance Committee are independent as defined in the listing standards of the NYSE.

The principal duties and responsibilities of the Nominating and Governance Committee are as follows:

• to establish criteria for Board and committee membership and recommend to the Board proposed nominees for election to the Board and for membership on committees of the Board;

The Nominating and Governance Committee operates under a written charter setting forth its functions and responsibilities. A copy of the current charter is available on our website at www.gbcholdings.com or in printed form upon request.

Communications to the Board

Stockholders and interested parties can contact the Board or our non-employee directors through written communication sent to Global Brass and Copper Holdings, Inc., 475 N. Martingale Road Suite 1050, Schaumburg, Illinois 60173, Attention: Anne-Marie W. D’Angelo, General Counsel and Corporate Secretary. Our General Counsel reviews all written communications and forwards to the Board or our non-employee directors, as applicable, a summary and/or copies of any such correspondence that is directed to the Board or our non-employee directors, as applicable, or that, in the opinion of the General Counsel, deals with the functions of the Board, Board committees or our non-employee directors, as applicable, or that she otherwise determines require their attention. Concerns relating to accounting, internal accounting controls or auditing matters are immediately brought to the attention of our internal audit department and handled in accordance with procedures established by the Audit Committee with respect to such matters.

Communications of a confidential nature can be made directly to the Chairman of the Audit Committee regarding any accounting, internal accounting control or auditing matter, by submitting such concerns to the Audit Committee. Any submissions to the Audit Committee should be marked confidential and addressed to the Chairman of the Audit Committee, c/o Global Brass and Copper Holdings, Inc., 475 N. Martingale Road Suite 1050, Schaumburg, Illinois 60173. Any submission should contain, to the extent possible, a full and complete description of the matter, the parties involved, and the date of the occurrence or, if the matter is ongoing, the date the matter was initiated and any other information that the reporting party believes would assist the Audit Committee in the investigation of such matter.

Succession Planning

Our Board maintains a detailed succession plan for the CEO and other key officers, which the Nominating and Governance Committee reviews at least once each year.

Director Compensation

The objectives for our non-employee director compensation program are to attract highly-qualified individuals to serve on our Board and align their interests with those of our stockholders. Our Compensation Committee reviews our director compensation program annually to confirm that the program remains appropriate and competitive, and recommends any changes to our full Board for consideration and approval. During 2017, the Compensation Committee engaged WTW, our independent compensation consultant, to provide a comprehensive review of compensation for non-employee directors and to make recommendations with regard to director compensation matters. Pursuant to this engagement, WTW found that our 2017 director compensation (described below) approximates the median of the Company’s peer group. As such, only minor adjustments (i.e., annual equity award was increased by $5,000) were made to the director compensation program in 2017 to ensure that director compensation continues to be generally aligned with market and peer group practice.

The following table shows the director fees earned by our non-employee directors for 2017. In addition, we reimbursed the directors for reasonable expenses incurred in attending Board meetings.

Director Compensation in 2017

Name	Fees Earned or Paid in Cash ($)	Stock Awards (1) ($)	Total ($)
Vicki L. Avril	75,000	105,000	180,000

Currently, our directors are eligible for an annual cash retainer of $75,000 and an annual equity award of $105,000.

The chair of the Compensation Committee receives an additional annual retainer of $15,000 and the chair of the Nominating and Governance Committee receives an additional $10,000 cash retainer.

At our May 26, 2016 Annual Meeting of Stockholders, our stockholders approved an amendment and restatement of the Global Brass and Copper Holdings, Inc. 2013 Omnibus Equity Incentive Plan (the “Omnibus Plan”). Pursuant to this amendment and restatement, the Omnibus Plan provides that a non-employee director may not receive in any calendar year stock awards under the Omnibus Plan with an aggregate grant date fair market value greater than $300,000, whether or not such awards are settled in cash or in stock; provided, however, that the foregoing limit shall not apply to any equity awards allowed under the Omnibus Plan a non-employee director elects to receive at fair market value in lieu of all or a portion of such non-employee director’s retainer.

Our directors’ stock ownership guidelines are summarized under the Equity-Based Compensation section in this proxy statement.

• Motivate through ownership. We believe that the best way to inspire leadership and performance is by distributing ownership in the form of equity-based compensation and requiring executive management to retain meaningful exposure to our stock.

Setting Executive Compensation

Our current executive compensation program is informed by input received from our compensation consultant, WTW, and prevailing market practices.

Role of Compensation Committee

We comply with the NYSE corporate governance rules, as all of the Compensation Committee members are independent, including under the specific independence standards for compensation committee members. See “Directors, Executive Officers and Corporate Governance-Other Board Information-Committees of the Board-Compensation Committee.” The Compensation Committee consists of Ronald C. Whitaker (Chairman), Vicki L. Avril, Donald L. Marsh, Bradford T. Ray and Martin E. Welch, III.

Role of Compensation Consultant

Our Compensation Committee has engaged WTW in order to benchmark compensation and make recommendations for future compensation (including cash, annual bonus and equity-based compensation) for our named executive officers. The Compensation Committee reviews and evaluates the results of WTW’s work and uses its judgment and best practices with respect to the Company’s executive compensation arrangements. Since 2012, WTW has reviewed our executive compensation programs and provided recommendations and advice to our Compensation Committee regarding such reviews.

Peer Group Benchmarking

In 2017, WTW benchmarked the named executive officer compensation against a peer group of sixteen companies, which were selected in part because they are similar in size to us. WTW benchmarked the components of base salary, annual performance-based cash bonuses, and long-term equity based compensation against the 25th percentile, median and 75th percentile of our peer group. The Board and Compensation Committee did not determine to target total compensation at any specific percentile, but concluded that the compensation for our named executive officers is at (or slightly above or below) the median of our peer group. The companies in our peer group used to determine compensation in 2017 were:

•    Briggs & Stratton Corporation	•    Materion Corporation
•    Carpenter Technology Corporation	•    Mueller Industries, Inc.
•    Century Aluminum Co.	•    Ryerson Holding Corporation
•    EnPro Industries	•    Schnitzer Steel Industries Inc.
•    Gibraltar Industries, Inc.	•    Titan International, Inc.
•    Harsco Corporation	•    Valmont Industries, Inc.
•    Kaiser Aluminum Corporation	•    Watts Water Technologies, Inc.
•    Kennametal Inc.	•    Worthington Industries, Inc.

Based on WTW’s recommendation, our Compensation Committee removed A.M. Castle & Co. (filed for Chapter 11 bankruptcy protection and has been delisted) and Olin Corp (merged with Dow Chemical’s chlorine business and our Compensation Committee decided that the newly merged entity would not qualify as being includable in our peer group). To replace both of these companies, based on WTW’s recommendation, our Compensation Committee added the following companies: (i) EnPro Industries, a $1.2B industrial machinery industry sector and (ii) Kennametal Inc., a $2.1B industrial machinery industry sector.

Advisory Vote on the Compensation of our Named Executive Officers

The Compensation Committee reviewed the results of the 2017 stockholder advisory vote on named executive officer compensation and considered the results as one of the many factors considered in connection with the discharge of its responsibilities. Since a substantial majority (over 91%) of our stockholders at the annual meeting approved the compensation program described in our 2017 proxy statement, the Compensation Committee did not implement any significant changes to our executive compensation program as a direct result of the stockholders’ advisory vote.

The Company is in regular contact with investors concerning compensation and other issues. For example, our Chief Financial Officer typically speaks with investors two or three times a month along with attending investor meetings and conferences two or three times a year.

Principal Components of Compensation of Our Named Executive Officers

The allocation between different elements of compensation with respect to our named executive officers is based on a review of comparable practices within our peer group. The compensation package offered to our named executive officers consists of the following principal components: base salary, annual performance-based cash bonuses, and long-term equity-based compensation.

We have entered into an employment agreement with Mr. Wasz, as well as severance protection agreements with each of our other named executive officers. For additional information regarding Mr. Wasz’s employment agreement and the severance protection agreements of Messrs. Kodosky, Bense, Denner, and Toler see the “Executive Compensation-Potential Payments Upon Termination or Change in Control” section of this proxy.

Base Salary

We provide our named executive officers with base salary to compensate them for services rendered during the year. We believe that base salary should compensate the executives for their service and performance but that superior contributions and performance should be rewarded by other forms of compensation, including long-term equity-based compensation.

17

The following table shows the base salaries of our named executive officers during the past three years.

Base Salaries

Name	Base Salary January 1, 2016 ($)	Base Salary January 1, 2017 ($)		Base Salary April 4, 2017 ($)		Base Salary December 31, 2017 ($)
John J. Wasz	825,000	825,000		825,000		825,000
Christopher J. Kodosky	270,000	360,000	(1)	385,000	(2)	385,000
William G. Toler	375,000	385,000		385,000		385,000
Kevin W. Bense	290,000	310,000		335,000	(2)	335,000
Devin K. Denner	340,000	340,000		365,000	(2)	365,000
Scott B. Hamilton	314,000	325,000		335,000	(2)	335,000

(1)	Due to Mr. Kodosky's promotion to become our Chief Financial Officer, his base salary was increased effective July 1, 2016.
(2)	After our independent compensation consultant (WTW) reviewed all of our named executive officers’ base salaries, our Compensation Committee, based on this review, increased the base salaries of Messrs. Kodosky, Denner, Bense and Hamilton, as noted above, to align their base salary at the median percentile of our peer group.

Annual Cash Bonuses

During 2017, the Board approved an annual bonus plan with performance targets based on Company performance and individual performance. The Compensation Committee set a target annual incentive for each named executive officer based on the scope of each executive’s duties and respective individual capacity to affect our overall performance as follows: 100% of base salary for Mr. Wasz, 60% of base salary for Mr. Kodosky, 55% of base salary for Mr. Toler, 60% of base salary for Mr. Bense, 60% of base salary for Mr. Denner, and 50% of base salary for Mr. Hamilton with potential maximum bonuses of two times each executive’s respective target bonus amount.

For 2017, for each named executive officer, other than Messrs. Bense and Denner, 70% of the annual bonus was based on the achievement of a financial metric of Adjusted Diluted Earnings per Common Share (defined below) (the “Financial Metric”) and 30% was based on the achievement of specific individual key measurable initiatives (the “Individual Bonus”). To be eligible for any portion of the Financial Metric, the Company was required to achieve a minimum of 85% of its Adjusted Diluted Earnings per Common Share target of $2.68. “Adjusted Diluted Earnings per Common Share” is a non-GAAP measure and is defined in our Annual Report on Form 10-K for the year ended December 31, 2017 in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” For Messrs. Bense and Denner, 50% of their annual bonus was based on achievement of Segment Adjusted EBITDA (defined below) at Chase Brass for Mr. Denner and at A.J. Oster for Mr. Bense (the “Segment EBITDA Bonus”), 25% was based on the Financial Metric and 25% was based on the Individual Bonus. “Segment Adjusted EBITDA” is a non-GAAP measure and is defined in our Annual Report on Form 10-K for the year ended December 31, 2017 in Note 4, “Segment Information,” to our Notes to Consolidated Financial Statements, as the “Adjusted EBITDA” for the Chase Brass and A.J. Oster segments.

Set forth below is a chart showing the sliding scale on which the named executive officer’s incentive compensation was based in terms of percentage of the budgeted Financial Metric and budgeted Segment Adjusted EBITDA component achieved and the payout as a percentage of his base salary. Linear interpolation of the Financial Metric and the Segment EBITDA Bonus payout occurs between 85% and 100% achievement of the respective target and separately between 100% and 110% achievement of the respective target, with a maximum payout of 200% of the component based on the level of achievement the respective target.

Level of Achievement of Financial Performance Target	% of Bonus Payout Based on Financial Performance Achievement
Less than 85%	—
85%	50
92.5%	75
100%	100
105%	150
110.0% (maximum)	200

18

For 2017, the target Financial Metric was $2.68. For 2017, we achieved a Financial Metric of $2.61, resulting in a payout of 91.3% for the Financial Metric component. In determining the level of achievement under the Financial Metric, our Compensation Committee adjusted the Financial Metric for insurance proceeds related to the 2016 Olin Brass Mill Outage and the impact of unexpected tax reform due to the Tax Cuts and Jobs Act.

The chart below sets forth the Financial Metric bonus that Messrs. Wasz, Kodosky, Toler and Hamilton achieved:

Name	Target Payout as a % of Salary	Actual Award ($)
John J. Wasz	70.0	527,258
Christopher J. Kodosky	42.0	147,632
William G. Toler	38.5	135,329
Scott B. Hamilton	35.0	107,049

The chart below sets forth the Financial Metric bonus that Messrs. Bense and Denner achieved.

Name	Target Payout as a % of Salary	Actual Award ($)
Kevin W. Bense	15.0	45,878
Devin K. Denner	15.0	49,987

For 2017, the target Segment Adjusted EBITDA for Chase Brass was $69.7 million, and Chase Brass achieved the maximum payout (200%). The target Segment Adjusted EBITDA for A.J. Oster was $19.9 million, and A.J. Oster achieved less than the threshold amount, which means no payout was earned.

The chart below sets forth the Segment EBITDA Bonus that Messrs. Bense and Denner achieved.

Name	Target Payout as a % of Salary	Actual Award ($)
Kevin W. Bense	30.0	—
Devin K. Denner	30.0	165,017

Each named executive officer’s Individual Bonus relates to the criteria necessary for such named executive officer to obtain any amount of the Individual Bonus from 0% to 200% of target. Messrs. Wasz, Kodosky, Toler and Hamilton were assessed on the progress they achieved in the efficiency, improvement, and sustainability of strategic, refinancing and growth initiatives both for the Company and for the individual business units, and improving investor awareness. Messrs. Bense and Denner were also assessed on the progress they achieved in supporting such growth initiatives, improving key strategies in the business units, and personnel initiatives, including developing improved human resources processes.

Overall, with respect to the aggregate assessment of the individual performance measures, the Compensation Committee determined that Mr. Wasz achieved 100% of his Individual Bonus goals, Mr. Kodosky achieved 130% of his Individual Bonus goals, Mr. Toler achieved 115% of his Individual Bonus goals, Mr. Hamilton achieved 115% of his Individual Bonus goals, Mr. Bense achieved 60% of his Individual Bonus goals and Mr. Denner achieved 135% of his Individual Bonus goals. The payouts based on the individual performance metrics are shown in the chart below.

Name	Target Payout as a % of Salary	Actual Award ($)
John J. Wasz	30.0	247,500
Christopher J. Kodosky	18.0	90,090
William G. Toler	16.5	73,054
Kevin W. Bense	15.0	30,150
Devin K. Denner	15.0	73,912
Scott B. Hamilton	15.0	57,788

The table below sets forth the amount of non-discretionary annual bonus earned for 2017 based on achievement of the Financial Metric and Segment Adjusted EBITDA, the amount that was earned based on individual objectives, the total actual award and the % of Base Salary.

Executive	Achievement of Financial Metric Criteria ($)	Achievement of Financial Metric & Segment Adjusted EBITDA Criteria ($)	Individual Objectives ($)	2017 Total Actual Award Paid ($)		% of Base Salary
John J. Wasz	527,258	—	247,500	774,758		93.9
Christopher J. Kodosky	147,632	—	90,090	237,722		61.7
William G. Toler	135,329	—	73,054	208,383		54.1
Kevin W. Bense	—	45,878	30,150	76,028	*	22.7
Devin K. Denner	—	215,004	73,912	288,916		79.2
Scott B. Hamilton	107,049	—	57,788	164,837		49.2

* In addition to the non-discretionary annual bonus earned for 2017 in the table above, our Compensation Committee paid Mr. Bense a transaction bonus of $30,000 in 2018 related to the successful consummation of the Alumet acquisition, which occurred in 2017. In addition to exemplary work regarding the successful consummation of the Alumet acquisition, our Compensation Committee, based on a recommendation from our independent compensation consultant (WTW), elected to provide this transaction bonus to Mr. Bense because this acquisition unfairly reduced any potential Segment EBITDA Bonus available to him to $0, which if left unrectified, our Compensation Committee decided would unfairly create a disconnect between pay and performance to Mr. Bense.

Equity-Based Compensation

Stock Options and Other Equity and Equity-Based Awards

In 2017, we granted performance share, stock option, and restricted stock awards to our named executive officers, under the Omnibus Plan, as further described below. Our long-term incentive opportunities directly connect executive compensation to Company performance. The equity grants our Compensation Committee made are structured to drive achievement of our business strategy while ensuring sharp focus on critical results and also on the passage of time. The amount awarded to each individual was based on the individual’s experience, competitive considerations, and input from our independent compensation consultant, which benchmarked our equity practices to ensure that we remain competitive with our peer companies. Our Compensation Committee approved a total long-term incentive opportunity for each named executive officer expressed as a percentage of such named executive officer’s base salary, as set forth in the table below. Total grant date award value was allocated 50% in the form of performance share awards, 25% in stock options, and 25% in restricted stock. Our Compensation Committee chose this allocation based on input from WTW regarding prevailing market practice and Our Compensation Committee’s desire to have a significant majority of the long-term incentive opportunity to be performance based. Total long-term incentive opportunities for our named executive officers approximated the median for comparable positions within our peer group (as provided in the “Compensation Discussion and Analysis-Peer Group Benchmarking” section of this proxy statement).

20

On February 9, 2017, the following awards were granted to our named executive officers:

Stock Awards Granted in 2017

Executive	Options #	Restricted Stock #	Performance Shares #	Total Grant Date Value of Equity Award ($)	Total Grant Date Value as Percentage of Base Salary (%)
John J. Wasz	44,380	16,195	32,390	2,196,012	266
Christopher J. Kodosky	10,105	3,688	7,374	500,001	130
William G. Toler	8,589	3,135	6,268	425,008	110
Kevin W. Bense	8,083	2,950	5,900	400,002	119
Devin K. Denner	9,094	3,319	6,637	450,001	123
Scott B. Hamilton	6,567	2,397	4,794	325,009	97

The options and restricted stock were made on terms consistent with the Omnibus Plan and will generally vest in three equal installments on each of the first, second and third anniversary of the date of grant, subject to continued employment on the applicable vesting date. All options were granted with an exercise price equal to the fair market value of a share of Company stock on the grant date.

In general, all performance shares granted in 2017 are scheduled to be earned in the following manner: (i) in the first quarter of 2019, our Compensation Committee will determine the amount of performance shares that are earned by our named executive officers based on our achievement of the return on invested capital performance criteria during the two year performance period that ends on December 31, 2018, (ii) 50% of the performance shares that are earned will be settled shortly after such determination is made and (iii) the remaining 50% of the performance shares that are earned are scheduled to vest and be settled one year after such determination of the performance criteria is made if the named executive officer remains employed through such payment date. All awards grated since 2015 have been subject to similar performance criteria and vesting terms.

In determining our performance goals, our Compensation Committee ensured the performance goals were aligned with the Company’s strategic plan and projected growth as well as our independent compensation consultant’s (WTW’s) assessment of the Company’s performance relative to our peer group, which, as noted below, has been consistently above the 75^th percentile in recent years.

On March 1, 2018, the remaining 50% of the performance shares related to the 2016 performance period were settled on March 1, 2017 because the time-based vesting criteria of these performance shares were met.

On March 7, 2018, the Compensation Committee certified that the performance criteria for the performance shares granted on February 11, 2016, were satisfied at the 150% level with respect to the two year performance period ending on December 31, 2017 and, pursuant to this determination, 50% of the applicable performance shares were settled on March 7, 2018. The remaining 50% are scheduled to vest and be settled on March 7, 2019, subject to continued employment through such date.

The performance share payouts for the performance periods ending in December 2016 and December 2017 were a result of our very strong relative (compared to our peer group) and absolute performance in fiscal years 2015, 2016 and 2017. For example, in 2018, our independent compensation consultant (WTW) reviewed our performance share payouts and determined that our return on invested capital (as well as several other financial metrics) were at or above the 75^th percentile of our peer group over the last three years. Moreover, WTW determined that our three year total shareholder return (TSR) was the highest in our peer group. Our Compensation Committee is determined to continue to set challenging performance goals moving forward with the expectation that maximum level performance share payouts will only occur as a result of exceptional performance.

21

Stock Ownership Guidelines

We maintain stock ownership guidelines for directors and members of senior management who participate in our equity compensation programs, to require those directors and members of senior management who participate in our equity compensation programs to meet the following minimum stock ownership guidelines.

Chief Executive Officer	4	Times Annual Base Salary
Chief Financial Officer, Chief Operating Officer, General Counsel and Business Unit Presidents	2	Times Annual Base Salary
Non-Executive Directors	4	Times Annual Retainer

To ease the financial burden of achieving these levels of stock ownership while ensuring that they will be met over time, it is expected that our directors and senior management will utilize their grants under our Omnibus Plan to reach the level of stock ownership required by the guidelines. In this regard, until the levels of ownership outlined above are achieved, directors and senior management are expected to retain a minimum of 75% of all shares (net of payment of options exercise prices, taxes and transaction costs) acquired pursuant to an award under the Omnibus Plan. During 2017, all of our directors and senior management have either met the minimum ownership thresholds or they have complied with the requirement that they retain a minimum of 75% of all shares acquired.

Risk Considerations in Our Compensation Program

The Compensation Committee, pursuant to its charter, is responsible for reviewing our employee compensation programs as they relate to risk management and risk-taking incentives. We do not believe that our compensation policies and practices give rise to risks that are reasonably likely to have a material adverse effect on us.

Our incentive compensation programs generally reward a mix of different performance measures, some of which are the financial performance measures. Additionally, our long-term incentives directly connect compensation to our performance by featuring stock options and performance shares. We believe that this mix of performance criteria mitigates any incentive to seek to maximize short-term performance at the expense of long-term performance or to maximize performance under one measure to the detriment of performance under another measure.

Maximum payouts under our incentive plans are capped at 200% of target payouts. We believe that these limits mitigate excessive risk-taking because the maximum amount that can be earned in a single cycle is limited. The incentive compensation for executives in key business segments is determined by company-wide performance measures as well as segment performance, to mitigate any incentive to pursue strategies that might maximize the performance of a single operating segment to the detriment of us as a whole.

Our senior management is subject to our stock ownership guidelines, which we believe incentivize our senior management to consider our long-term interests and our stockholders��� long-term interests. Additionally, these guidelines discourage excessive risk-taking that could negatively impact our stock price. Our incentive compensation programs are designed with payout curves that are relatively smooth and do not contain steep payout “cliffs” that might encourage short-term business decisions in order to meet a payout threshold.

In December 2014, the Company adopted our Incentive Compensation Recoupment Policy (the “Recoupment Policy”) to provide for recovery of incentive compensation, if any, in excess of what would have been paid to our executive officers or former executive officers in the event that the Company is required to restate its financial results.

On an annual basis, the Compensation Committee reviews, along with our independent compensation consultant WTW, the Audit Committee, our Chief Financial Officer and our senior risk officers, our employee compensation programs as they relate to risk management and risk-taking incentives in order to determine whether any risk arising from such compensation programs is reasonably likely to have a material adverse effect on the Company.

Incentive Compensation Recoupment Policy

The Recoupment Policy is a written clawback policy that we maintain. The Recoupment Policy applies to all incentive based cash and equity compensation awards granted on or after the effective date (“Incentive Compensation”) to any current or former executive officer of the Company (collectively, the “Covered Recipients”). In the event that the Company is required by applicable U.S. federal securities laws to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under such securities laws where such accounting restatement was caused or substantially caused by the intentional misconduct of the Covered Recipient, the Company will recover from such Covered Recipient who received Incentive Compensation during the three-year period preceding the date on which the Company is required to prepare an accounting restatement, based on the erroneous data, the amount, if any, in excess of what would have been paid to the Covered Recipient under the accounting restatement.

22

The Recoupment Policy is administered by the Compensation Committee, which has the sole discretion in making all determinations under the Policy. The Recoupment Policy will be interpreted and administered (and, as necessary, amended to be) consistent with the applicable requirements of Section 10D of the Exchange Act, as added by Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and any official guidance issued thereunder.

Anti-Hedging and Anti-Pledging Policy

Pursuant to the Company’s securities trading policy, directors, executive officers and other employees are prohibited from pledging any shares of stock or engaging in any hedging transactions involving or referencing Company securities.

Actions After Close of the Fiscal Year

In February and March 2018, the Compensation Committee made grants of annual cash bonuses, performance share awards and restricted stock under the Omnibus Plan. These grants were of the same type, and generally in the same aggregate amounts, as granted in prior years, except that starting in 2018, (i) our Compensation Committee changed the mix of equity awards granted to our named executive offices, such that our named executive officers will not receive any grants of stock options, but rather equity grants to our named executive officers will be subject to a 60/40 allocation (60% of which is allocated to performance shares and 40% allocated to restricted stock); and (ii) our Compensation Committee increased Mr. Kodosky’s target annual incentive to 65% of his base salary. Additionally, after our independent compensation consultant (WTW) reviewed all of our named executive officers’ base salaries, in April 2018, our Compensation Committee, based on this review, increased the base salaries of all of our named executive officers to align their base salary at the median percentile of our peer group.

Tax and Accounting Considerations

Deductibility of Executive Compensation

In general, Code Section 162(m) limits the amount that we may deduct from our Federal income taxes for remuneration paid to our ”covered employees” (as defined by Code Section 162(m)) up to one million dollars per covered employee per year. Prior to the enactment of the Tax Cuts and Jobs Act, Code Section 162(m) provided an exception from this deduction limitation for certain forms of “performance-based compensation,” as well as for the gain recognized by named executive officers upon the exercise of qualifying compensatory stock options with respect to taxable years beginning on or before December 31, 2017. Due to the enactment of the Tax Cuts and Jobs Act, the aforementioned performance-based compensation exception will no longer apply to taxable periods beginning after December 31, 2017, unless the compensation meets certain transition relief provided under Code Section 162(m) (i.e., remuneration, which is provided pursuant to a written binding contract in effect on November 2, 2017).

In the past, our Compensation Committee generally sought to structure performance-based compensation for our covered employees in a manner that complies with Code Section 162(m) in order to provide for the deductibility of such compensation and to the extent possible, our Compensation Committee will continue to structure performance-based compensation in a similar manner. However, the Compensation Committee may use its business judgment to determine (as done from time to time in the past) that it is in our best interest to provide for compensation that may not be fully deductible.

Taxation of “Parachute” Payments and Deferred Compensation

We do not maintain any arrangements that would provide any of our named executive officers any “gross-up” or other reimbursement payment for any tax liability that such individual might owe as a result of the application of Sections 280G, 4999, or 409A of the Code. Sections 280G and 4999 of the Code provide that executive officers, certain highly compensated employees, directors who hold significant equity interests and certain other service providers may be subject to an excise tax if they receive payments or benefits in connection with a change in control that exceeds certain prescribed limits, and that we, or a successor, may forfeit a deduction on the amounts subject to this additional tax. Section 409A of the Code also imposes additional significant taxes on the individual in the event that an executive officer, director or other service provider receives “deferred compensation” that does not meet the requirements of Section 409A of the Code.

Potential Payments Upon Termination or Change in Control

Employment Agreement with John J. Wasz

Mr. Wasz, our President, Chief Executive Officer and Chief Operating Officer, is party to an employment agreement, dated as of May 8, 2014. Mr. Wasz’s employment agreement provides him with severance benefits upon certain terminations of employment. Mr. Wasz’s employment can be terminated at any time and for any reason. If Mr. Wasz’s employment is terminated by us for “cause” (as defined below) then he is only entitled to receive any base salary that had been earned but not paid through the date of termination. If his employment is terminated due to his death or disability, he is entitled to (a) the base salary accrued through the date of termination, (b) pay for any vacation time earned but not taken, (c) any earned but unpaid bonus for the year prior to termination, and (d) any business expenses incurred by him but unreimbursed on the date of termination, provided that such expenses and required

28

substantiation and documentation thereof are submitted within thirty (30) calendar days of termination and that such expenses are reimbursable under our policy (collectively, “Final Compensation”).

Mr. Wasz’s employment can be terminated by us without “cause” or by him for “good reason.” Upon such a termination, he is entitled to receive: (a) two years of base salary, (b) his target annual bonus, (c) health, dental, and life insurance coverage for a period of one year.

“Cause” under Mr. Wasz’s employment agreement generally means any of the following:

• the failure or refusal to perform the duties of his position after written notice from the Board;

• willful misconduct or gross negligence in the performance of his duties that has an adverse effect on our operations after receipt of at least one warning from us;

• intentional breach by the executive of a written covenant with us or of a written policy, in each case relating to the use and preservation of intellectual property and/or confidentiality;

• being impaired by or under the influence of alcohol, illegal drugs or controlled substances while working or while on our property;

• conviction of or plea of nolo contendere to a felony; or

• dishonest, disloyal or illegal conduct or gross misconduct that materially and adversely affects his performance or our reputation or business (it being agreed that a petty offense or a violation of the motor vehicle code shall not constitute “cause”).

Prior to the determination that “cause” has occurred with respect to any of the grounds listed above other than a conviction of or plea of nolo contendere to a felony, Mr. Wasz will have a 30-day cure period to remedy such breach, unless, in the Board’s discretion, the “cause” event is incapable of reasonably prompt cure or if the Board determines that its fiduciary duty requires such termination.

“Good reason” under Mr. Wasz’s employment agreement generally means any of the following events occurring without his consent:

• our failure to continue Mr. Wasz in the position of President and Chief Executive Officer;

• our requiring that Mr. Wasz report to an individual or body other than the Board;

• a material diminution in Mr. Wasz’s position with us or the duties and responsibilities associated with such position; or

• a material reduction of Mr. Wasz’s base salary, annual target bonus opportunity, benefits, and annual equity incentive awards in the aggregate, excluding any reduction in Mr. Wasz’s annual equity incentive awards that (a) is applicable to all similarly situated executives or (b) is 10% or less and results from adjustments to the allocation of a fixed pool among similarly situated executives.

Mr. Wasz is required to provide written notice of any event claimed to constitute “good reason” within 30 days after the initial occurrence of such event and to provide us with an opportunity to cure the applicable circumstance within 30 days following such written notice. If we fail to cure such circumstance, Mr. Wasz’s resignation for “good reason” must be tendered, if at all, within 60 days after our failure to cure.

Mr. Wasz is subject to non-competition and non-solicitation covenants for 24 months post-termination, which applies to the 24-month period following his resignation. In addition, he is subject to perpetual confidentiality covenants.

Severance Protection Agreement with Christopher J. Kodosky

Mr. Kodosky, our Chief Financial Officer, is party to a severance protection agreement, dated as of July 11, 2016. Mr. Kodosky’s employment may be terminated by us at any time for any reason. If Mr. Kodosky’s employment is terminated by us without “cause” or if he resigns for “good reason,” he would be entitled to a severance payment in a cash lump sum, equal to (i) one year of base pay at the highest rate of base salary during the one-year period immediately prior to the termination and (ii) the higher of (x) the target annual bonus amount for the year preceding the termination and (y) the average annual bonus earned and paid over the three years immediately prior to his termination. Mr. Kodosky and his dependents will also be entitled to continued health and welfare participation for one year following such termination, unless he obtains coverage from a new employer and COBRA coverage at the end of such one-year period if he has not obtained new coverage.

Mr. Kodosky’s severance protection agreement generally uses the same definitions of “cause” and “good reason” as Mr. Wasz’s employment agreement, except that, (i) under Mr. Kodosky’s severance protection agreement “good reason” includes any assignment of duties materially and adversely inconsistent with his position, any material reduction in his base salary, target annual cash bonus opportunity plan, benefits, and annual equity incentive awards in the aggregate, excluding any reduction in his annual equity incentive

29

awards that (a) is applicable to all similarly situated executives or (b) is twenty percent (20%) or less and results from adjustments to the allocation of a fixed pool among similarly situated executives, any requirement that his principal place of employment is other than our principal executive office or there is a change in his principal place of employment that increases the distance between his residence as of the date of this Agreement to his principal place of employment by more than fifty (50) miles (ii) and Mr. Kodosky must give written notice of a claim for good reason within 60 days of its initial occurrence.

Additionally, a payment will be received with respect to performance shares based on actual performance for the entire performance period, prorated based on the time elapsed from the date of grant to the date employment terminated. The amounts in the above table are based on the closing price of Company stock on December 29, 2017 (the last trading day of the fiscal year), which was $33.10. Based on a death or disability occurring on December 31, 2017, the same accelerated vesting amounts determined under footnote three (3) would apply to footnote four (4).

The information contained in this Report shall not be deemed to be “soliciting material” or to be “filed” with the SEC or subject to Regulation 14A or 14C other than as set forth in Item 407 of Regulation S-K, or subject to the liabilities of Section 18 of the Exchange Act, except to the extent that we specifically request that the information contained in this Report be treated as soliciting material, nor shall such information be incorporated by reference into any past or future filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except to the extent that we specifically incorporate it by reference in such filing.

AUDIT COMMITTEE REPORT

The Audit Committee of the Board is responsible for evaluating audit performance, appointing, compensating, retaining and overseeing the work of our independent registered public accounting firm and evaluating policies and procedures relating to internal accounting functions and controls. The Audit Committee is currently comprised of Ms. Avril and Messrs. Marsh, Ray, Welch and Whitaker, each a non-employee and independent director, and operates under a written charter.

The Audit Committee members are neither professional accountants nor auditors, and their functions are not intended to duplicate or to certify the activities of management and the independent auditor, nor can the Audit Committee certify that the independent auditor is “independent” under applicable rules. The Audit Committee serves a board-level oversight role in which it provides advice, counsel and direction to management and the auditors on the basis of the information it receives, discussions with management and the auditors and the experience of the Audit Committee’s members in business, financial and accounting matters. Our management has the primary responsibility for the financial statements and reporting process, including our systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed with management the audited consolidated financial statements included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2017, as well as the report of management and the opinion thereon of PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm, for the year ended December 31, 2017, regarding the Company’s internal control over financial reporting required by Section 404 of the Sarbanes-Oxley Act.

The Audit Committee has discussed with PricewaterhouseCoopers LLP, our independent registered public accounting firm, the matters required to be discussed under the Public Company Accounting Oversight Board standards (“PCAOB”). The Audit Committee has also received written disclosures and the letter from PricewaterhouseCoopers LLP required by applicable requirements of the PCAOB regarding PricewaterhouseCoopers LLP’s communications with the Audit Committee concerning independence and has discussed with PricewaterhouseCoopers LLP its independence from the Company.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board that the Company’s audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, filed with the SEC on March 1, 2018.

The information contained in this Report shall not be deemed to be “soliciting material” or to be “filed” with the SEC or subject to Regulation 14A or 14C, other than as set forth in Item 407 of Regulation S-K, or subject to the liabilities of Section 18 of the Exchange Act, except to the extent that we specifically request that the information contained in this Report be treated as soliciting material, nor shall such information be incorporated by reference into any past or future filing under the Securities Act or the Exchange Act, except to the extent that we specifically incorporate it by reference in such filing.

This Report is submitted by Ms. Avril and Messrs. Marsh, Ray, Welch and Whitaker, being all of the members of the Audit Committee.

CHIEF EXECUTIVE OFFICER PAY RATIO

As required by the SEC, we are providing the following information regarding the relationship of our median employee’s annual total compensation compared to the annual total compensation of Mr. Wasz, our Chief Executive Officer.

Identification of Median Employee

We selected December 31, 2017 as the date on which to determine the median employee. As of that date, we had approximately 1,980 employees (1,899 in the United States and Puerto Rico and 81 outside of the United States). For purposes of identifying the median employee, we used 2017 taxable year-to date compensation as our consistently applied compensation measure. To identify the median employee, we excluded 81 non-U.S. employees from the following jurisdictions: 33 from the Republic of China, 41 from Mexico and 7 from Singapore. After applying this exemption, we analyzed a total of 1,899 employees to determine the median employee.

In determining the annual total compensation of the median employee and our Chief Executive Officer, we calculated their compensation in accordance with Item 402(c)(2)(x) of Regulation S-K as required by the SEC. This calculation is the same calculation used to determine annual total compensation reported above in the Summary Compensation Table for our Chief Executive Officer. We believe that the pay ratio disclosed below is a reasonable estimate calculated in a manner consistent with the applicable SEC disclosure rules.

2017 Chief Executive Officer Pay Ratio

	2017 Annual Total Compensation		CEO Pay Ratio
John J. Wasz	$	3,851,471	56:1
Median Employee	$	68,909

This above information is being provided solely for compliance purposes. Because our Compensation Committee has determined the ratio is not an adequate indicator of linking pay with performance, our Compensation Committee does not materially consider this ratio when evaluating compensation arrangements.

36

FEES OF INDEPENDENT ACCOUNTANTS

In addition to retaining PricewaterhouseCoopers LLP to audit our consolidated financial statements for 2017, we retained PricewaterhouseCoopers LLP, as well as other accounting firms, to provide tax and other advisory services in 2017. We understand the need for PricewaterhouseCoopers LLP to maintain objectivity and independence in its audit of our consolidated financial statements.

In order to assure that the provision of audit and permitted non-audit services provided by PricewaterhouseCoopers LLP, our independent registered public accounting firm, does not impair its independence, the Audit Committee is required to pre-approve the audit and permitted non-audit services to be performed by PricewaterhouseCoopers LLP, other than de minimis services that satisfy the requirements pertaining to de minimis exceptions for non-audit services described in Section 10A of the Exchange Act. The Audit Committee has adopted policies and procedures for pre-approving all audit and permitted non-audit work performed by PricewaterhouseCoopers LLP. Any pre-approval must also set forth in detail the particular service or category of services approved and is generally subject to a specific cost limit. All of the fees for audit, audit-related, tax and other services performed by PricewaterhouseCoopers LLP were pre-approved by the Audit Committee in accordance with the pre-approval policies and procedures described in this paragraph.

The Audit Committee has adopted policies regarding our ability to hire employees, former employees and certain relatives of employees of the Company’s independent registered public accounting firm.

During 2017 and 2016, we retained PricewaterhouseCoopers LLP to provide services in the following categories and amounts:

	2017		2016
Audit fees (1)	$	3,130,000	$	2,690,900
Audit-related fees (2)	30,000		—
Tax fees (3)	—		70,000
All other fees	—		—
Total	$	3,160,000	$	2,760,900

(1)	Audit fees consist of fees incurred for the audit of our annual consolidated financial statements and review of our quarterly consolidated financial statements that are normally provided by PricewaterhouseCoopers LLP in connection with consents and reviewing documents to be filed with the SEC.
(2)	Audit-related fees consist of fees incurred for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements and are not reported under “Audit fees.” In 2017, audit-related fees included fees billed for professional services provided in connection with the new revenue recognition standard.
(3)	Tax fees include professional services in connection with tax compliance and advice.

37

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

We maintain and enforce a Related Person Transaction Policy, which sets forth our policy with respect to the review, approval, ratification and disclosure of all related person transactions by our Audit Committee. In accordance with our Related Person Transaction Policy, our Audit Committee has overall responsibility for the implementation and compliance with this policy.

For the purposes of our Related Person Transaction Policy, a “related person transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we were, are or will be a participant and in which any related person (as defined in our Related Person Transaction Policy) had, has or will have a direct or indirect material interest in excess of $10,000. A “related person transaction” does not include any employment relationship or transaction involving an executive officer and any related compensation resulting solely from that employment relationship which has been reviewed and approved by the Board or Compensation Committee.

Our Related Person Transaction Policy requires that notice of a proposed related person transaction be provided to our legal department prior to entering into such transaction. If our legal department determines that such transaction is a related person transaction, the proposed transaction will be submitted to our Audit Committee for consideration at its next meeting. Under our Related Person Transaction Policy, our Audit Committee will only be permitted to approve those related person transactions that are in, or not inconsistent with, our best interests. In the event we become aware of a related person transaction that has not been previously reviewed, approved or ratified under our Related Person Transaction Policy and that is ongoing or is completed, the transaction will be submitted to the Audit Committee so that it may determine whether to ratify, rescind or terminate the related person transaction.

Our Related Person Transaction Policy also provides that the Audit Committee will review certain previously approved or ratified related person transactions that are ongoing to determine whether the related person transaction remains in our best interests and the best interests of our stockholders.

In addition, our Code of Business Conduct and Ethics prohibits activities that conflict with, or have the appearance of conflicting with, the best interests of the Company and its stockholders. Such conflicts of interest may arise when an employee, or a member of the employee’s family, receives improper personal benefits as a result of such individual’s position in the Company.

Certain Transactions

There were no related party transactions in 2017.

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

(PROPOSAL NO. 2)

Our Audit Committee has appointed PricewaterhouseCoopers LLP as our independent registered public accounting firm for the year ending December 31, 2018. A proposal will be presented at the Annual Meeting to ratify this appointment. Ratification of the appointment of our independent registered public accounting firm requires the affirmative vote of the majority of shares present in person or represented by proxy at the Annual Meeting and entitled to vote. If the stockholders fail to ratify such selection, another independent registered public accounting firm will be considered by our Audit Committee, but the Audit Committee may nonetheless choose to engage PricewaterhouseCoopers LLP. Even if the appointment of PricewaterhouseCoopers LLP is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders. We have been advised that a representative of PricewaterhouseCoopers LLP will be present at the Annual Meeting and will be available to respond to appropriate questions and, if such person chooses to do so, make a statement.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” RATIFICATION OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2018.

PROXIES SOLICITED BY THE BOARD WILL BE VOTED FOR THE PROPOSAL UNLESS STOCKHOLDERS SPECIFY A CONTRARY VOTE.

39

ADVISORY VOTE TO APPROVE, ON AN ADVISORY BASIS, THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS, AS SET FORTH IN THIS PROXY STATEMENT

(PROPOSAL NO. 3)

Pursuant to Section 14A of the Exchange Act, we are seeking the advisory approval by stockholders of the compensation of our named executive officers, as disclosed in this proxy statement. While this vote is advisory, and not binding on the Board, it will provide information to the Board and Compensation Committee regarding investor sentiment about our executive compensation programs and practices, which the Compensation Committee will carefully review when evaluating our executive compensation program. In 2014, our stockholders approved a non-binding resolution to require an advisory vote on the compensation of our named executive officers every year, and accordingly, we have elected to provide this vote annually.

Stockholders are being asked to vote on the following advisory resolution:

“RESOLVED, that the Company’s stockholders approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed in the 2018 proxy statement pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the 2017 Summary Compensation Table and the other related tables and disclosures.”

The Company is committed to maintaining executive compensation programs and practices that are aligned with the Company’s business strategy.

We urge our stockholders to read the “Compensation Discussion and Analysis” section above, which describes in detail how our executive compensation program and practices operate and are designed to achieve our compensation objectives, as well as the accompanying compensation tables, which provide detailed information on the compensation of our named executive officers.

The affirmative vote of a majority of the shares of common stock present in person or represented by proxy and entitled to be voted on the proposal at the Annual Meeting is required for approval of this advisory resolution.

THE BOARD RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS SET FORTH IN THIS PROXY STATEMENT.

PROXIES SOLICITED BY THE BOARD WILL BE VOTED FOR THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS SET FORTH IN THIS PROXY STATEMENT UNLESS STOCKHOLDERS SPECIFY A CONTRARY VOTE.
