PROPOSAL NO. 1
ELECTION OF DIRECTORS

        The first proposal on the agenda for the 20152018 Annual Meeting is the election of Marc A. Kastner and Gilles J. Martin to serve as Class II directors for a two-year term beginning at the 2015 Annual Meeting and ending at our 2017 Annual Meeting of Stockholders or until a successor has been duly elected and qualified and the election of Richard D. Kniss, Joerg C. Laukien, William A. Linton, Ph.D. and Chris van IngenAdelene Q. Perkins to serve as Class III directors for a three-year termterms beginning at the 20152018 Annual Meeting and ending at our 20182021 Annual Meeting of Stockholders or until a successor has been duly elected and qualified. The Company's Certificate of Incorporation, as amended, provides that the board of directors shall consist of three classes of directors with overlapping three-year terms. One class of directors is to be elected each year for a three-year term. Directors are assigned to each class in accordance with a resolution or resolutions adopted by the board of directors, each class consisting, as nearly as possible, of one-third the total number of directors. There are currently tentwelve members of our board of directors, consisting of four Class I directors serving terms expiring at the Company's Annual Meeting of Stockholders in 2016, one2019, four Class II directordirectors serving a termterms expiring at the Company's 2020 Annual Meeting of Stockholders in 2017 and fivefour Class III directors serving terms expiring at the Company's Annual Meeting of Stockholders in 2015. There is currently one vacancy within the class of Class II directors.2018.

        Effective as of the 20152018 Annual Meeting, in conjunction with the expiration of the terms of the fivefour current Class III directors, the number of directors will be reduced to eleven and the classes will be adjusted to consist of four Class I directors, three

four Class II directors and fourthree Class III directors, leaving an additional vacancy within the class of Class II directors. At the 20152018 Annual Meeting, fourthree nominees will be elected as Class III directors to serve for terms expiring at the 20182021 Annual Meeting of Stockholders. Additionally, although our bylaws provide that vacancies may remain unfilled or may be filled by a majority vote of the directors then in office, two nominees will be elected as Class II directors to serve for terms expiring at the 2017 Annual Meeting of Stockholders to fill the two vacancies in the class of Class II directors.

        Marc A. Kastner, one of the nominees for Class II director, previously served as a director of the Company from February 2013 to the expiration of his term in May 2014. Dr. Kastner was not nominated for election to an additional term at the Company's 2014 Annual Meeting of Stockholders because at that time his appointment to serve as Director of the Office of Science of the U.S. Department of Energy was awaiting confirmation by the United States Senate. Having not yet received Senate confirmation, Dr. Kastner withdrew his name from consideration in early 2015, thus making him again eligible for service on our board of directors. Gilles J. Martin, the other nominee for Class II director, is currently serving as a Class III director. Each of the nominees for Class III director, Richard D. Kniss, Joerg C. Laukien, William A. Linton, Ph.D. and Chris van Ingen,Adelene Q. Perkins, was previously elected by our stockholders and is currently serving as a Class III director. All nominees were unanimously approved by our board of directors, including unanimous approval by our independent directors, upon the unanimous recommendation of the Nominating Committee, which is comprisedCommittee.

        Richard D. Kniss, who has served as a Class III director since 2003, has not been nominated for re-election and, accordingly, his service on the board of three independent directors.directors will terminate at the 2018 Annual Meeting.

        Unless marked otherwise, proxies received will be votedFOR the election of each of the nominees for the office of director. If any such nominee is unwilling or unable to serve as a nominee for the office of director at the time of the 20152018 Annual Meeting, the proxies may be voted for a substitute nominee who shall be designated by the present board of directors to fill such vacancy. Alternatively, if no such nominee is designated, a vacancy will be created in Class II or Class III, as applicable.III. The board of directors has no reason to believe that any of the nominees will be unwilling or unable to serve if elected as a director.

        The Board of Directors recommends a vote FOR the election of Marc A. Kastner and Gilles J. Martin to serve as Class II directors and FOR the election of Richard D. Kniss, Joerg C. Laukien, William A. Linton, Ph.D. and Chris van IngenAdelene Q. Perkins to serve as Class III directors.

Nominees for Election to a Two-YearThree-Year Term Expiring at the 20172021 Annual Meeting

BOARD LEADERSHIP STRUCTURE

        Under our bylaws, the chairman of the Company's board of directors has the power to preside at all meetings of the board. Dr. Frank Laukien, our Chief Executive Officer and President, serves as the Chairman of our board of directors and has done so throughout the time we have been a public company. Although the board believes that the combination of the Chairman and Chief Executive Officer roles is appropriate in the current circumstances, the board does not have a fixed policy regarding the combination or separation of the offices of Chairman and Chief Executive Officer. Our board of directors believes that it should have the flexibility to make these determinations at any given point in time in the way that it considers best to provide appropriate leadership for the Company at that time.

        The Chief Executive Officer is appointed by our board to manage the Company's daily affairs and operations. Dr. Laukien's extensive industry knowledge and long history of direct involvement in the Company's operations make him best suited to serve as Chairman in order to (i) lead the board in productive discussions on important matters affecting the Company; (ii) create a firm link between management and the board and promote the development and implementation of corporate strategy; (iii) determine necessary and appropriate agenda items for meetings of the board with input from the independent lead director and board committee chairpersons; and (iv) determine and manage the amount of time and information devoted to discussion and analysis of agenda items and other matters that may come before the board. Additionally, his significant equity ownership, at over 23%approximately 26% of the outstanding shares of the Company's common stock, means that he has a close and direct alignment of interests with the interests of our other shareholders.stockholders.

        While we believe that having a unified Chairman and Chief Executive Officer is appropriate and in the best interests of the Company and its shareholdersstockholders at this time, our board structure also fosters strong oversight by independent directors. Since 2004, an independent lead director has been appointed by the independent directors to ensure an independent leadership contact. The lead director's responsibilities include: (i) consulting with the Chairman regarding agenda items for board meetings; (ii) chairing executive sessions of the independent directors; (iii) calling executive sessions of the independent directors of the board and advising the Chairman and Chief Executive Officer of actions or deliberations at such sessions; (iv) acting as a liaison between the independent directors and the full board, as necessary; and (iv) establishing, in consultation with the Chairman and Chief Executive Officer and any appropriate board committees, procedures to govern the board's work, ensuring that the board of directors is appropriately approving strategy and supervising management's progress. Dr. William Linton has served in the role of lead director since the position was established in 2004. Our Chairman and Chief Executive Officer consults periodically with the lead director on governance matters and on issues facing the Company. In addition, the lead director serves as the principal liaison between the Chairman and the independent directors and presides at executive sessions of independent directors at regularly scheduled in-person board meetings. The board of directors believes that this approach appropriately and effectively complements the Company's combined Chairman and Chief Executive Officer.

BOARD MEETINGS, COMMITTEES AND COMPENSATION

        There are currently tentwelve members of our board of directors. EightTen of our current directors, namely Wolf-Dieter Emmerich, Stephen W. Fesik, Brenda J. Furlong,Cynthia M. Friend, Marc A. Kastner, Richard D. Kniss, William A. Linton, Gilles J.G. Martin, John Ornell, Richard A. Packer, Adelene Q. Perkins, Hermann Requardt and Chris van Ingen,Robert Rosenthal, meet the independence requirements of the NASDAQ Stock Market LLC, or NASDAQ, listing standards. All of our director nominees, other than Mr. Joerg C. Laukien, are independent under such standards. Our former director, Chris van Ingen, was also determined to be independent when serving as a member of our board. In making its independence determinations, the board of directors considered, among other things, relevant transactions between the Company and entities associated with the independent directors, as further described in this proxy statement under

these rules, we are required to have an Audit Committee consisting of at least three independent members. The Audit Committee met seven times during 2014 in regular session. From time to time, the Audit Committee also held meetings or teleconferences to discuss certain topics, including, but not limited to, the Company's review of legal compliance matters at certain of its subsidiaries operating in China and Hong Kong. Ms. Furlong,2017. Mr. Ornell, Chair of the Audit Committee, qualifies as an audit committee financial expert pursuant to applicable SEC rules and regulations.

        The Audit Committee provides assistance to the board of directors in fulfilling its legal and fiduciary obligations with respect to matters involving the accounting, auditing, treasury, financial reporting and internal control functions of the Company and its subsidiaries. The Audit Committee works extensively with the independent auditors, pre-approves all audit and non-audit services provided to the Company by its independent auditors, reviews the performance of the independent auditors and replaces or terminates the independent auditors when circumstances warrant. The Audit Committee is also charged with establishing and monitoring procedures for (i) the receipt, retention or treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters, and (ii) the confidential submission by the Company's employees of concerns regarding questionable accounting or auditing matters. None of the members of the Audit Committee has participated in the preparation of any financial statements of the Company at any time during the last three fiscal years. The Audit Committee's charter is available on the Company's website at http:https://ir.bruker.com under the "Corporate Governance" section.

        Compensation Committee.    The Compensation Committee which is comprisedcurrently consists of Wolf-Dieter Emmerich, Stephen W. FesikRichard D. Kniss, Hermann Requardt and Richard D. Kniss,Packer, all of whom meet the independence requirements of the NASDAQ Listing Rules,listing rules. The Compensation Committee met eight times and acted by unanimous written consent four times during 2014.2017. Mr. Kniss is the ChairmanChair of the Compensation Committee. The Compensation Committee (i) administers the Company's stock incentive plan; (ii) determines the chief executive officer's salary, bonus, and equity based compensation; (iii) oversees the executive compensation program for the Company's other executive officers; and (iv) determines such compensation, reviews general policy matters relating to compensation and employee benefits and makes recommendations concerning these matters to the board of directors. From time to time, the Company expects that various of its senior executive officers will provide analysis and recommendations to the Compensation Committee on compensation issues, as requested by the Compensation Committee. In particular, the Chief Executive Officer annually evaluates the performance of the executive officers who report directly to him, including, without limitation,among others, the Chief Financial Officer, and makes recommendations to the Compensation Committee regarding such executive officers' compensation. Additionally, the Chief Financial Officer provides the Chief Executive Officer input on the annual evaluations of the performance of the Company's other named executive officers and makes recommendations to the Compensation Committee regarding the

compensation of these executive officers. The Compensation Committee reviews these performance evaluations and recommendations and discusses the recommendations with our Chief Executive Officer and, as appropriate, our Chief Financial Officer. In some cases, these discussions may lead to adjustments to an executive officer's performance evaluation and compensation recommendation. In other cases in which the Compensation Committee deems it appropriate, the evaluations and management recommendations may be approved by the Compensation Committee with little or no change. Our Chief Executive Officer, Chief Financial Officer and the Global Vice Presidentour Corporate Senior Director of Human Resources may routinely attend meetings of the Compensation Committee to provide information relating to matters the Compensation Committee is considering. The Compensation Committee may, from time to time, meet in executive session without any executive officers or other members of management present. The Compensation Committee's charter is available on the Company's website at http:https://ir.bruker.com under the "Corporate Governance" section.

        The Company anticipates appointing an incumbent independent director to succeed Mr. Kniss in his Compensation Committee assignments prior to the 2018 Annual Meeting.

        Nominating Committee.    The Nominating Committee is comprisedcurrently consists of Wolf-Dieter Emmerich,Marc A. Kastner, Richard A. Packer and William A. Linton, and Richard A. Packer, all of whom meet the independence requirements of the NASDAQ Listing Rules.listing rules. Mr. Packer is the ChairmanChair of the Nominating Committee. The purpose of the Nominating Committee is to assist the board in identifying and recruiting individuals qualified to become board members, consistent with criteria approved by the board, and to recommend to the board nominees for election to the office of director at the next annual meeting of stockholders, or for election to fill any vacancies between annual meetings. While the board of directors retains responsibility for selecting nominees and recommending them for election by the Company's stockholders, the Nominating Committee is responsible for developing and implementing a process to identify qualified and willing candidates for recommendation to the board. The Nominating Committee is assisted by non-voting advisors from our board, including Dr. Frank Laukien, our Chairman, President, CEO and largest stockholder, and Mr. Joerg Laukien, a director and significant stockholder. The role of the advisors is to provide input to the Nominating Committee as major shareholders of the Corporation. The Nominating Committee's charter is available on the Company's website at http:https://ir.bruker.com under the "Corporate Governance" section.

        The Nominating Committee met three timesone time and acted by unanimous written consent once during 2014.2017. In addition, to these meetings, members of the Nominating Committee communicated periodically throughout the year regarding candidates for director and director nomination matters. At a meeting held in February 2015,2018, the Nominating Committee unanimously recommended each of the current nominees for director to the full board of directors.

        In addition to the standing committees described above, in 2013 the board of directors established a temporary BEST Special Committee, comprised of Chris van Ingen, Frank Laukien and Joerg Laukien, to focus on key issues relating to the Company's Bruker Energy and Supercon Technologies division.

DIRECTOR NOMINATIONS

        On March 3, 2004, the Company adopted a policy by board resolution governing the nomination of directors, according to which the full board of directors approves all nominees for board membership. All nominees must also be approved by a majority of the Company's independent directors. Upon recommendation of the Nominating Committee, the qualifications of candidates will be reviewed by at least a majority of the independent directors of the Company, as well as the full board of directors. Stockholders may recommend director candidates for inclusion by the board of directors in the slate of nominees which the board recommends to stockholders for election as described below.

        The process followed to identify and evaluate potential candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by the members of the Nominating Committee, the independent directors and the board.

The Nominating Committee, the independent directors and the board are each authorized to retain advisers and consultants and to compensate them for their services. No such advisers or consultants were retained for this purpose during 2014.2017.

        The Company does not have a formal policy with regard to the consideration of diversity in identifying director nominees, but strives to identify and recruit director candidates with a variety of complementary skills, expertise and backgrounds so that, as a group, the board will possess the appropriate talent, skills and expertise to oversee the Company's business. WhenThe Committee seeks to promote through the nominations process an appropriate diversity in board composition, recognizing that the Corporation's businesses and operations are diverse and global in nature. In considering a potentialindividual director candidate,candidates, the Nominating Committee evaluatestakes into account such factors as diversity in professional experience, skills and background, as well as diversity in gender, race and ethnicity. Search firms retained to assist the entirety of each candidate's experienceCommittee are advised to actively seek to identify qualified, diverse candidates, including women and qualifications. The Nominating Committee looks for personal and professional integrity, demonstrated ability and judgment and business experience.minorities.

        In considering whether to recommend any candidate for inclusion in the board's slate of recommended director nominees, the board and the independent directors apply the criteria which are set forth in a resolution of the board approved and adopted on March 3, 2004.

        These criteria include, but are not limited to, the following:

•

experience in aspects of business or technology relevant to the Company's business;



•

sufficient time available to devote to the affairs of the Company;



•

character and integrity;



•

ability to represent the best interests of stockholders as a whole rather than special interest groups;



•

willingness to participate actively as a board member; and



•

communication, decision-making and interpersonal skills.

        The board and the independent directors may also consider the following for some of the director nominees:

•

experience serving as a director of a public company;



•

familiarity with corporate governance issues;



•

independence, as determined in accordance with SEC rules and regulations and NASDAQ listing standards;



•

experience in running a comparable company or division of a comparable company;



•

insight into the Company, its strategy, business model, operations, and financials;



•

knowledge of industry trends and markets; and



•

qualification as an "audit committee financial expert" to serve on the Audit Committee in accordance with SEC and NASDAQ definitions.

        In evaluating candidates recommended by the Nominating Committee, the board and the independent directors do not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. We believe that the backgrounds and qualifications of the directors, considered as a group, should provide a significant composite mix of experience, knowledge, backgrounds and abilities that will allow the board to fulfill its responsibilities.

        Although the Company does not have a specific policy with respect to the nomination of directors by stockholders, the Nominating Committee will consider nominations made by stockholders. The Company believes that it is not necessary to have a policy for director nominations by stockholders because the board of directors, including the Nominating Committee and the independent directors, is

able to effectively locate and evaluate potential candidates for nomination to the board of directors due to the directors' intimate knowledge of the Company and the life science industry. However, stockholders may communicate directly with the Nominating Committee of the board of directors by written communication submitted to Richard M. Stein at the address set forth below under "Stockholder Communications." Mr. Stein shall be primarily responsible for monitoring the communications and providing summaries or copies of such communications to the Nominating Committee or the board of directors as he deems appropriate, and, as described below, will submit communications to the Nominating Committee or the board of directors, as appropriate, relating to corporate governance matters and long-term corporate strategy. Stockholders may use this process to suggest potential nominations to the board of directors. Such suggested nominations shall be forwarded to the Nominating Committee and the proposed candidates shall be evaluated using substantially the same process and applying the same criteria as used and applied in evaluating candidates submitted by board members. Nominations must be received by the Company within the timeframe set forth herein under "Time for Submission of Stockholder Proposals."

        At the 20152018 Annual Meeting, stockholders will be asked to consider the re-election of Richard D. Kniss, Joerg C. Laukien, William A. Linton, Ph.D. and Chris van IngenAdelene Q. Perkins to serve as Class III directors and the election of Marc A. Kastner and Gilles J. Martin to serve as Class II directors. Each of the nominees is standing for election following the unanimous recommendation for nomination first by the Nominating Committee, and then by the full board of directors, including the unanimous approval of all of the Company's independent directors.

ROLE OF THE BOARD IN RISK OVERSIGHT

        Our board of directors considers general oversight of the Company's risk management efforts to be a responsibility of the entire board. The Audit and Compensation Committees assist the board in carrying out this responsibility by focusing on specific key areas of risk that our business faces. The board's role in risk oversight includes receiving regular reports from members of senior management on areas of material risk to the Company, or to the success of a particular project or endeavor under consideration, including operational, financial, legal and regulatory, strategic and reputational risks. The full board of directors, the Audit Committee in the case of financial and compliance risks that are within the oversight of the Audit Committee or the Compensation Committee in the case of matters relating to our compensation policies and practices, receives these reports from members of management to enable the board or the Audit or Compensation Committee, as applicable, to understand the Company's risk identification, risk management, and risk mitigation strategies. To facilitate this process and assist the Audit Committee in fulfilling its responsibility for monitoring legal and compliance risks, our senior director of internal audit, who reports directly to our Senior Vice President, Corporate Finance and Accounting,Chief Financial Officer, also has a dotted line reporting relationship to the chairperson of the Audit Committee. The Audit Committee chairperson is authorized to give instructions and assignments directly to the senior director of internal audit, as to which assignments the director of internal audit reports directly and only to the Audit Committee chairperson. When a report is evaluated at the Audit Committee level, the chairperson of the Audit Committee subsequently reports on the matter to the full board to ensure coordination of the board's risk oversight activities. Our board of directors also believes that risk management is an integral part of our strategic planning process, which addresses, among other things, the risks and opportunities facing the Company.

Executive Overview

        Our executive compensation program is designed to attract, motivate, retain and reward the individuals thatwho lead the Company.Company and who are responsible for developing and executing the overall business strategy. Our approach to compensation for our executive officers targets a mix of competitive salaries, performance-based cash incentive awards linked to corporate and individual objectives and long-term equity incentive awards. The majority of our executive officers' pay opportunities are in the form of incentives, rather than base salary, with a significant amount of those opportunities tied to long-term equity incentive awards, thereby strongly linking the interests of our overall pay program with those of our shareholders. We provide limited perquisites and no excise tax gross ups. We also have a recoupment ("clawback") provision under our 2017 incentive plans that allows us to seek reimbursement of short-term incentive payments and repayment of stock award gains in the following circumstances: (a) to the extent of the excess of what would have been paid to the participant in the event of a restatement, due to material noncompliance with any financial reporting requirements, that is required to be prepared at any time during the three-year period following such payment or (b) in the event the recipient engages in activities that are detrimental to the business of the Company.

        We believe that our compensation policies and practices are effectively designed to motivate and reward performance, and that the mix of compensation elements creates incentives that are closely aligned with increasing shareholder value without encouraging excessive or unnecessary risk-taking.

2017 Financial Performance

        Our business strategy is to create value for our stockholders based on our ability to innovate and generate revenue growth, both organically and through acquisitions. Achieving improvements in our gross profit margins, operating margins, earnings and cash flow are also criticalimportant to our success. In 2014,2017, our revenues declinedincreased by approximately 2%$154.6 million, or 9.6%, to $1.81 billion$1,765.9 million from $1.84 billion, reflecting a difficult economic environment$1,611.3 million in certain of our key markets, as well as the impact of changes in foreign exchange rates.2016. Included in 2014our 2017 revenues were a decreasewas an increase of approximately $25.4$77.2 million attributable to our recent acquisitions and an increase of approximately $19.6 million from the impact of foreign exchange due tocurrency translation caused by the strengtheningweakening of the U.S. Dollar versus the Japanese Yen, Russian Rubleeuro and other currencies, and an increasecurrencies. Excluding the effects of approximately $2.9 million attributable to recent acquisitions and divestitures. Adjusted for changes in foreign exchange ratescurrency translation and our recent acquisitions, and divestitures, our 2014 revenues decreasedorganic revenue, a non-GAAP financial measure, increased by $8.0$57.8 million, or 0.4%3.6%. Our gross profit declinedmargin remained

Excluding various charges for amortization of acquisition-related intangible assets and our gross profit margin for fiscal 2014 dropped to 42.2% from 43.8% for fiscal 2013. On a non-GAAP basis, excluding the effects ofother acquisition-related costs and restructuring charges totaling,costs, our non-GAAP gross profit margin also was consistent at 48.1% in each of the aggregate, $44.4 millionyears ended December 31, 2017 and $27.3 million2016. Operating income for the year ended December 31, 2014 and 2013, respectively, our gross profit margins declined approximately 60 basis points to 44.7% for fiscal 2014,

Ourthe year ended December 31, 2016. The operating incomemargin increase reflected improved operating leverage on higher sales following our multi-year operational transformation, cost discipline and savings from restructuring initiatives. These factors more than offset dilution from recent acquisitions and foreign currency translation effects.

However, as a resultthe year ended December 31, 2016. For the year ended December 31, 2017, we reported GAAP diluted earnings per share (EPS) of a combination of improvements$0.49, compared to $0.95 for the year ended December 31, 2016. The decrease in our inventory management programs andGAAP EPS was primarily attributed to charges related to the estimated impact of U.S. tax reform legislation which resulted in a significantly higher effective tax rate for the year ended December 31, 2017. On a non-GAAP basis, our diluted non-GAAP EPS for the year ended December 31, 2017 of $1.21 compared to $1.19 for the year ended December 31, 2016, which in turn had benefited from an unusually favorable effects of foreign exchange on our operating costs, oureffective tax rate in fiscal year 2016.

        Organic revenue, non-GAAP gross profit margin, non-GAAP operating margin and non-GAAP EPS are non-GAAP financial measures we use to supplement our financial results prepared and presented in accordance with U.S. generally accepted accounting principles (GAAP).⁽¹⁾ The Compensation Committee considers these non-GAAP measures, as well as other non-GAAP measures, when setting incentive compensation targets. We use these non-GAAP financial measures to evaluate

Non-GAAP Financial Measures—For additional information regarding our organic revenue, non-GAAP gross profit margin and non-GAAP operating margin non-GAAP financial measures, including reconciliations to the most directly comparable GAAP financial measures, please see pages 41 to 42 and pages 45 to 47 under Part II, Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report on Form 10-K filed with the SEC on March 16, 2018. Non-GAAP EPS includes the following adjustments to our reported GAAP EPS:

our period-over-period operating performance because our management believes they provide more comparable measures of our continuing business because they adjust for certain items that are not reflective of the underlying performance of our business. These measures may also be useful to investors in evaluating the underlying operating performance of our business. We regularly use these non-GAAP financial measures internally to understand, manage, and evaluate our business results and make operating decisions. We also measure our employees and compensate them, in part, based on such non-GAAP measures and use this information for our planning and forecasting activities. The presentation of these non-GAAP financial measures is not intended to be a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP and may be different from non-GAAP financial measures used by other companies, and therefore, may not be comparable among companies.

        We remained focusedIn 2017, we significantly exceeded the performance goals for each of the financial performance goals established by the Compensation Committee at the Corporate level, other than our goal linked to reducing our working capital ratio. Specifically, our Corporate level goals linked to currency-adjusted revenue growth, increasing our non-GAAP operating profit and meeting our earnings per share target were exceeded. Our goal of reducing our working capital ratio was not achieved. Our underlying business results also were generally favorable, with the Bruker CALID and Bruker Nano Groups overachieving with respect to their Group level currency-adjusted revenue growth, non-GAAP gross profit improvement and non-GAAP operating profit improvement metrics, though not achieving their Group level goals related to reducing the working capital ratio. The Bruker BioSpin Group did not achieve its Group level financial objectives in 20142017. Our management team also continued to make significant progress returning the business to positive revenue growth, as well as on variousa number of strategic initiatives aimed at reducing our operating costs and improving our operating efficiency. For example, in 2014 we commenced a plan to divest certain assets and implement a restructuring program in the Bruker CALID Group's CAM division as a result of management's conclusion that the CAM business would be unable to achieve acceptable financial performance in the next two years. In the second half of 2014, we completed the sale of certain assets of the CAM division, including the Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) product line and the Gas Chromatography (GC) and GC Single Quadrupole Mass Spectrometry (GC-SQ-MS) sales and manufacturing business. Restructuring and other one-time charges in connection with this plan totaled approximately $24 million in 2014,efficiency, which was partially offset by a gain we recognized on the sale of the product lines of $8 million. As a result of lower revenues, adverse changes in foreign exchange rates, costs relating to our restructuring initiatives and investments in infrastructure improvements, our GAAP earnings per share declined to $0.33 per share in 2014 from $0.48 per share in 2013 and our 2014 non-GAAP earnings per share fell to $0.75 from $0.77 for 2013.

        Although we significantly exceeded our goal for improvement in our working capital ratio, we did not fully achieve the other financial goals established by the Compensation Committee for 2014. However, our management team made significant progress on a number of strategic initiatives that we believe will benefit the Company and ultimately contribute to positive shareholder value creation.creation over the long-term. Consequently, consistent with our pay for performance philosophy, the 20142017 cash incentive awards approved for our executive officers reflectedreflect these mixedgenerally strong results at the Corporate and Group levels and were below targetedsubstantially above target award amounts.levels.

2017 Executive Compensation Actions

        Highlighted below are some of the key actions and decisions with respect to our executive compensation programs for fiscal year 2014,2017, as approved by the Compensation Committee:

•

Salaries.  For fiscal 2014,2017, the Compensation Committee evaluated our executive officers' base salaries in light of competitive market levels and approved a 9%5.2% salary increase for Dr. Frank Laukien, our Chief Executive Officer. The Compensation Committee considered this adjustment appropriate based on peer group survey data, as Dr. Laukien's base salary and total target cash compensation continue to be significantly below the market median for chief executive officers of the Company's compensation peer group. The 20142017 base salaries for each of our other executive officers, other than Mr. Knell, were set at levels which the Compensation Committee considered appropriate given their respective responsibilities, overall performance and competitive market conditions.conditions with salary increases ranging from 5% to 7%.



•

Performance-Based Cash Incentive Awards and Payouts.  Consistent with our pay-for-performance philosophy, a significant portion of our executive officers' total compensation potential for fiscal 20142017 was linked to achievement of corporate and individual quantitative and qualitativeperformance goals. AsAdditionally, as executive officers assume greater responsibility, a larger portion of their total cash compensation is designed to and does become dependent on and varies based on Company and individual performance. For example, the Chief Executive Officer's variable cash compensation comprisesrepresented nearly 60% of his total cash compensation opportunity based on target levels. For the remaining named executive officers, cash-based variable pay comprises approximately 33% to 50%represented nearly 40% of total cash

compensation based on target levels, tying a substantial amountover one-third of their total earnings opportunity to strategic performance objectives which are aligned with shareholder value creation.




•

As within past years, the Compensation Committee established specific fiscal year 20142017 financial quantitative and individual qualitativeperformance goals for our executive officers. Quantitative financial performanceFinancial goals represented 70% of each of our executive officers' total cash incentive compensation potential, with the remaining 30% allocated to individual qualitative performance goals established by the Compensation Committee.



•

A frequency of once every year received the highest number of votes cast, as well as a majority of the votes cast on the proposal. Our Board of Directors considered these results and determined that we will hold an annual advisory say on pay vote.

Over 98%97% percent of the shares voted on the matter at the 20142017 Annual Meeting of Stockholders approved the compensation decisions and policies described in the 20142017 proxy statement. The Compensation Committee considered this result in 20142017 and determined that it was not necessary to make any material changes to the Company's compensation policies and practices in response to the most recent advisory vote. However, the Compensation Committee regularly reviews the compensation programs of our executive officers to ensure that they achieve our objectives.

Consistent with these results, our stockholders will next be asked to cast an advisory vote regarding executive officer compensation at the Company's 20172023 Annual Meeting of Stockholders.

Executive Compensation Philosophy and Process

Key Considerations in Setting Compensation

        Our key objectives in structuring and determining executive compensation are to:

•

attract and retain qualified executive officers by offering competitive and comprehensive compensation packages;



•

motivate existing officers to perform by providing meaningful incentive-based compensation;



•

align compensation with Bruker Corporation's annual and long-term strategic performance goals; and



•

balance both the short-term goals of the Company with a focus on creating long-term value for our stockholders, without encouraging excessive or unnecessary risk-taking.

        To achieve these objectives, we have embraced a compensation philosophy that seeks to align compensation with our strategic objectives and reward our executive officers for meeting or exceeding certain pre-determined performance goals. Executive compensation at Bruker is based in large part on a pay-for-performance philosophy, through annual incentive bonus awards which emphasize both company and individual performance measures that correlate closely with the achievement of our short and long term strategic performance objectives. To motivate our executive officers, we focus on cash compensation in the form of salary and annual performance incentives, a portion of which is tied to the individual's performance, and we augment this cash compensation with equity grants. In structuring executive compensation, the Compensation Committee focuses on our goal of long-term enhancement of stockholdershareholder value through grants of equity incentive awards with extended multi-year vesting schedules.




Role of the Compensation Committee

        Our executive compensation program is administered by the Compensation Committee of the board of directors. The Compensation Committee oversees the Company's equity incentive plan, including determining overall option and restricted stock award guidelines and aggregate share usage and dilution levels, determines the Chief Executive Officer's salary, target and actual bonus, and equity-based compensation, oversees the executive compensation program for our other executive officers, including reviewing and approving the overall values and forms of compensation for the named executive officers listed in the Summary Compensation Table included in this proxy statement as well as for other officers, reviews general policy matters relating to compensation and employee benefits and makes recommendations concerning these matters to the board of directors.




        The Compensation Committee conducts the annual performance evaluation of our Chief Executive Officer. Generally, the process begins with the Chief Executive Officer completing a self-evaluation, which is submitted to the Compensation Committee for review and discussion. As part of this review, the ChairmanChair of the Compensation Committee may solicit views from other members of our board of directors, after which the ChairmanChair of the Compensation Committee provides feedback to the Chief Executive Officer. The Compensation Committee uses this evaluation along with market data comprised of peer group and salary survey information in setting the Chief Executive Officer's compensation.

        For executive officers other than our Chief Executive Officer, the Compensation Committee relies primarily on input and recommendations from our Chief Executive Officer in the case of our Chief Financial Officer and Group presidents. In the case of our other executive officers who report directly to our Chief Executive Officer, the Compensation Committee relies primarily on the input and recommendations from our Chief Financial Officer. Our Chief Executive Officer, Chief Financial Officer and our Global Vice PresidentCorporate Senior Director of Human Resources also may contribute input to the Compensation Committee in connection with its evaluation of executive officers' performance objectives and performance of the executive officers against those objectives to assist it in making appropriate decisions regarding salary and incentive awards. The Global Vice PresidentCorporate Senior Director of Human Resources may also provide market analyses and other relevant market intelligence to the Compensation Committee as part of its evaluation and deliberations.

        Prior to the end of the first quarter of each fiscal year, the Compensation Committee reviews and approves changes to our executive officers' total target cash compensation, including base salary and target incentive compensation. During the first quarter of each fiscal year,Also during this time, the Compensation Committee also reviews recommendations from management on the most recently completed fiscal year short-term incentive compensation programs relative to anticipated corporate and individual performance. Additionally, during the first quarterthird and fourth quarters of each fiscal year, the Compensation Committee reviews and makes recommendations to the full board of directors regarding any changes to board compensation. The Compensation Committee generally reviews recommendations for long-term equity incentive awards during the second and third quarters of the fiscal year.

        The Compensation Committee assesses competitive market compensation for our executive officers using a variety of external sources, including cash and long-term incentive compensation data derived from independent sources, including market surveys and proxy information, for a reference group of publicly-traded companies in the same or similar industries. Although individual pay is driven largely by individual and corporate performance considerations, the Compensation Committee has historically used reference group data as a "market check" to help ensure that individual cash compensation levels remain reasonable and competitive. In September 2013, theThe Company has retained independent consulting firm Radford Consulting, or Radford, since September 2013 to provide support in evaluating the Company's executive compensation levels and practices, particularly with respect to total direct compensation, internal pay equity, pay for performance alignment, and long-term incentive award levels, and types of equity vehicles and processes, including the impact of overall shareholderstockholder dilution resulting from equity awards.




        The Compensation Committee retains the discretion to approve awards in excess of those calculated to have been earned under the pre-established cash incentive plans of our executive officers in recognition of exceptional individual performance or contributions to Company performance. Additionally, the Compensation Committee may exercise its discretion not to approve cash incentive plan awards calculated to have been earned under a pre-established cash incentive plan of an executive officer in the event the Compensation Committee determines that such executive officer has violated Company policies or has failed to meet minimum performance expectations of an executive officer in that executive's position. The Compensation Committee may also recoup incentive compensation payments if it determines that a recipient has engaged in activities detrimental to the Company's business, as well as excess payments made resulting from a financial restatement which results from material non-compliance with accepted financial requirements or reporting standards.




Role of Management

        The Chief Executive Officer, with the assistance of the Chief Financial Officer, is responsible for making recommendations to the Compensation Committee for our Company-wide financial performance goals and their respective weightings. He is also responsible for making recommendations to the Compensation Committee for the individual incentive goals and weightings for the Company's other executive officers. The Chief Executive Officer is also responsible for developing and providing a proposal to the Compensation Committee for his own cash incentive plan, including the goals, weightings and target levels. The Compensation Committee reviews the recommendations of the Chief Executive Officer and Chief Financial Officer and determines the final incentive plan structure and goals for each of the executive officers, including threshold performance and target incentive paymentperformance levels. After the close of the fiscal year, the Chief Executive Officer, assisted by the Chief Financial Officer and the Senior Director of Human Resources, provides the Compensation Committee with his assessment of the performance of the other executive officers against their respective bonus goals and proposed cash incentive payout. When determining the cash incentive plan payout for our executive officers, the Compensation Committee, while considering the recommendations of the Chief Executive Officer, and Chief Financial Officer, makes the final determination based on its assessment of each executive officer's performance relative to his or her performance-based goals.

        The Chief Executive Officer Chief Financial Officer and Global Vice Presidentthe Senior Director of Human Resources participate in Compensation Committee meetings, at the request of the Compensation Committee, to provide background information and explanations supporting compensation recommendations, including the results of annual performance evaluations for our Chief Executive Officer, and Chief Financial Officer conduct onand our other named executive officers. The Chief Financial Officer also participates in Compensation Committee meetings to provide perspective and supplemental information related to the Company's financial goals and other financial plan topics.

Role of Compensation Consultants

        In light of the growth and evolution in recent years in the size and complexity of the Company and its global operations, changes in the competitive landscape as a result of industry consolidation and changes in the Company's own organizational and management structure, the Compensation Committee and management have worked with compensation consultantsRadford to, among other things, providereview market surveys, observations and recommendations regarding our executive compensation program relative to other similarly situated public companies.companies and receive external perspectives on evolving trends related to executive compensation program design, best practices and changes in the regulatory landscape.

        InSince September 2013, Company management retainedhas engaged Radford to provide support to management and the Compensation Committee, including the selection of a new peer group of companies and expandeddevelopment of peer group survey data, as well as analysis and advice on the Company's executive compensation structure, program design and market practices. Services provided during fiscal 20132017 by




Radford under its engagement with the Company included working with the Company to develop a newassess the current peer group to be used for reasonableness and various compensation assessments, analyzing the Company's executive compensation pay levelsanalyses and practices, including the Company's share allocation and utilization as compared with selected peer companies, and providing advice with respect to incentive plan design changes.assessments. The analyses and recommendations provided by Radford were among the inputs considered in the evaluation of the Company's compensation process, program design and executive compensation determinations for 2014.2017. The selected peer group is generally used for compensation assessments and analyzing the Company's executive compensation pay levels and practices, including the Company's share allocation and utilization for employee equity awards as compared with peer companies.

        Aon and Aon Hewitt, affiliates of Radford, also provided human resourcesinsurance consulting services to the Company in 20132017 for which services they received aggregate fees of $118,000 in 2014.$52,500. For its services as an executive compensation consultant to the Company, Radford received aggregate fees of $52,000approximately $84,000 in 2014, and an additional $64,9462017, as well as approximately $43,000 for non-executive compensation consulting and surveys. The Compensation Committee has assessedevaluated Radford's independence by considering each of the independence of Radfordfactors adopted by NASDAQ and the SEC. Based on such evaluation, the Committee determined that Radford is independent and that no conflicts of interest existed during fiscal 20142017 or exist currently. The Compensation Committee has the authority to retain, compensate and terminate any consultants or advisers it deems necessary to assist it in the fulfillment of its responsibilities.




Peer Group Review and Market Data

        In establishing and evaluating fiscal 20142017 compensation for our executive officers, as well as for executive officers hired in 2014, the Compensation Committee utilized survey market data and peer group analysis provided by Radford. The Compensation Committee believes that it is important to consider compensation practices of companies that are comparable to us in terms of revenue, market capitalization, employees, global reach, scale and complexity, along with industry. Radford generally targeted companies in the range of 1/2 to three times the size of the Company across various categories, considering the global complexity and reach of the Company. The market data provided by Radford was based on published survey sources, including Radford's Global Technology Survey and Aon Hewitt's Total Compensation Management Database, as well as recent proxy statements of the Company's peer group companies. The Compensation Committee references ranges of the market data provided, including the 25^th, 50^th,10th, 25th, 50th, and 75^th75th percentiles, considering all of these sources in determining the appropriate level of compensation for our executive officers.

        For fiscal 20142017 compensation evaluations, the peer group identified by Radford and referenced by the Compensation Committee was comprised of 1716 other companies in the scientific tools, instruments, and services industries. The Compensation Committee believes that a peer group consisting of broad competitors of various sizes provides useful insight for theirits consideration of compensation levels, including information about the range and median of competitive salaries, cash bonuses and long-term incentives. In addition to industry, complexity and size characteristics, the Compensation Committee also considers the extent to which our selected peer group companies consider us a peer, how other third-party organizations categorize the Company, such as the Standard and Poor's GICS methodology, and other companies which shareholder advisory firms, such as ISS, consider comparable to us. The Committee also strives for consistency in the peer group from year to year, to maintain consistency of results. The same peer group has generally been used since 2013, with modifications primarily due to industry consolidation. In 2017, at the time Radford compiled data for the peer group companies, the companies in theour selected peer group ranged in size on a revenue basis from approximately $800 million$1.97 to $3.3$3.0 billion, at the 25th and 75th percentiles, respectively, with a median of $2$2.3 billion, as compared to our trailing twelve month revenue of $1.8$1.6 billion, and a range of 5,560 to 12,675 employees at the 25th and 75th percentiles, respectively, with median number of employees of 6,2007,900 compared to our 6,400.




6,200. The peer group considered by the Compensation Committee for its evaluation of 2014 base salary2017 executive compensation levels and annual cash incentive targets of our executive officerspractices included:

• AMETEK, Inc.Agilent Technologies		• KLA-Tencor CorporationIllumina Inc.
• Bio-Rad Laboratories,AMETEK,  Inc.		• Mettler-Toledo International Inc.KLA-Tencor Corporation
• C.R. Bard,Bio-Rad Laboratories,  Inc.		• OSI Systems,Mettler-Toledo International Inc.

• FLIR Systems,  Inc.		• Sigma-Aldrich CorporationPerkinElmer,  Inc.
• Haemonetics Corporation		• Varian Medical Systems,  Inc.
• Hologic,  Inc.		• Waters Corporation
• Illumina Inc.

        In general, in light of our relative market position, the Compensation Committee considered the range and median compensation levels of the companies in the peer group to be appropriate and reasonable competitive comparisons for our executive officers when evaluating and approving 20142017 compensation packages.

Executive Compensation Components and 20142017 Compensation Determinations

        Consistent with our compensation objectives and philosophy, when setting compensation for our named executive officers the Compensation Committee focuses on providing a competitive and complementary mix of pay components, including base salary, annual incentive compensation and long-term equity incentive awards, designed to work together to reward performance and create incentives that encourage behavior consistent with the overall short- and long-term interests of the Company.

        In determining compensation packages for our named executive officers, the Compensation Committee seeks to strike an appropriate balance between fixed and variable compensation and between short-and long-term compensation. We believe that making a significant portion of our named executive officers' compensation variable and long-term supports our pay-for-performance executive compensation philosophy, while also mitigating potential excessive risk-taking behavior.




Components of Executive Compensation

        Total direct compensation consists of cash compensation in the form of annual base salary and annual incentive bonus awards, as well as long-term incentive compensation in the form of stock option and restricted stock grants.

        Annual Base Salary.    Base salaries are determined based on a variety of factors, including each officer's level of responsibility, scope of the role, experience and potential, performance and a comparison of salaries paid to peers within the Company and to those with similar roles at other similarly situated companies.companies, including those found in the market surveys and peer group data reviewed by the Compensation Committee. Base salaries are set at levels that the Compensation Committee believes are reasonably competitive to allow us to attract and retain qualified executives. Base salaries are reviewed annually and may be adjusted after considering the various factors described above.

        Annual Cash Incentive Awards.    Annual incentive awards in the form of performance-based cash incentive bonuses for the Chief Executive Officer and our other executive officers are based upon management's success in meeting our financial and strategic goals. Specific criteria for these awards are based on a combination of quantitative financial and qualitative individual measures established each year by the Compensation Committee after consultation with management. The specific goals vary for each executive officer based on responsibilities and role within our Company and may include financial or strategic measures, including, among others, revenue growth, gross profit and operating profit margin improvement, working capital ratio improvements, achieving return on invested capital goals, meeting earnings per share targets, identifying and developing new product and market opportunities and furthering or achieving other strategic initiatives. The individual goals are intended to reward performance which results in our Company meeting or exceeding its financial or operational goals.




        The Compensation Committee also considers the mix of performance goals in order to balance the incentives created to mitigate risks that may be associated with a particular performance goal. In 2014,2017, for example, and as in recent prior years, the cash incentive compensation plans, or ICPs, established for our corporate level officers, including our Chief Executive Officer and Chief Financial Officer, consisted of a revenue target goal along with targets for non-GAAP operating profit improvement, improvement in working capital and non-GAAP earnings per share, such that the combination of goals emphasized profitprofitable revenue growth and cash flow improvements as well as top-line revenue growth performance based on the business plan approved by our board of directors. For our Group presidents, the financial metrics included Group level revenue growth, increases in Group level non-GAAP gross and operating profit and gross profit, improvements in Group level working capital, andas well as linkage to the overall Bruker profit resultsnon-GAAP earnings per share result, to ensure alignment and teamwork across the leadership team. Through a mix of quantitative financial metrics and qualitative individual goals, cash incentive awards reflect both the individual's contributions compared to his or her specific performance goals for the year and the overall performance of our Company or the particular operations under the executive officer's leadership.

        Long-Term Incentive Awards.    Equity incentive compensation in the form of stock optionsoption, restricted stock awards and restricted stock unit (RSU) awards is designed to provide long-term incentives to executive officers and other employees, to encourage the executive officers and other employees to remain with us and to enable recipients to develop and maintain a long-term stock ownership position in our common stock, which in turn motivates the recipient to focus on creating long-term enhancement to stockholdershareholder value. The

        Effective as of its approval by our stockholders in May 2016, the Company's 20102016 Incentive Compensation Plan, or the 2016 Plan, is the vehicle used for grants of stock options and restricted stockequity incentive awards to our executive officers and other employees. Prior to the approval of the 2016 Plan, equity incentives in the form of stock option and restricted stock awards were granted pursuant to the Company's 2010 Incentive Compensation Plan. The 2016 Plan provides for the grant of awards of options, including nonqualified stock options or incentive stock options, restricted stock, unrestricted stock, restricted stock units, stock appreciation rights, performance shares and performance units, as well as cash-based awards. Following adoption of the 2016 Plan, we shifted to the use of RSU awards from restricted stock awards to provide a more tax-effective equity vehicle for our international employees and additional flexibility for the Company to deliver awards in the form of stock or cash. The Company management evaluates the efficacy of our long-term incentive compensation on an ongoing basis and provides input and recommendations to the Compensation Committee with regard to the optimal form and extent of equity incentives to be granted to employees, including the executive officers.

        Stock option and restricted stock grantsEquity incentive awards are discretionary and may be granted by the Compensation Committee at any time. Historically, we have not awarded equity incentive compensation with performance-based vesting, meaning that individual vesting is not based upon the achievement of




any specific pre-determined goals or objectives. However, increases in stock price provide the only value available to executives from stock options, and increases in shareholder value deliver higher values in the restricted stock.stock and RSU awards held by our executive officers and other key personnel. The Compensation Committee also considers individual and Company performance in determining the value of total and individual equity awards. The Compensation Committee has determined that equity compensation awards to executives and all other employees should be based upon the economic value of the grant award and should be considered part of the overall compensation package in determining award levels. In making specific grants to executives, the Compensation Committee evaluates each executive officer's total equity compensation package. The Compensation Committee also generally reviews the option and restricted stock holdings of each of the executive officers, as well, including vesting and exercise price and the then current in-the-money value of such options or restricted stock, in addition to the impact of those values under various stock price scenarios. We consider long-term equity compensation to be an integral part of a competitive executive compensation package as both a way to reinforce the




individual's commitment to the Company, create an ownership mentality and provide an important mechanism to align the interests of management with those of our stockholders.

Mix of Compensation

        In accordance with our pay-for-performance philosophy, variable compensation in the form of short-term cash incentive compensation and long-term equity incentive awards are intended to be a significant portion of overall compensation, with this at-risk component increasing as a percentage of overall compensation potential as the individual officer's responsibility increases. For example, almost 80%approximately 84% of the Chief Executive Officer's total compensation is variable or "at risk.risk," meaning these amounts must be re-earned each year. Similarly, over two-thirdsalmost 69% of the other NEO total compensation of our other named executive officers is comprised of variable pay.

        Specifically, on a target basis in 20142017, approximately 57%58% of our Chief Executive Officer's total potential cash compensation at the target level was at risk through his short-term cash incentive program. Additionally, recognizing the importance of providing further incentives directly linked to the performance of our common stock and aligned with shareholderstockholder interests, in 20142017 the Compensation Committee approved market competitive long-term incentive awards to our named executive officers, including, among others, awards to Dr. Laukien, our Chief Executive Officer, and Mr. Wagner,Mattacchione, our Chief Financial Officer during fiscal year 2017, of stock options and restricted stock grantsRSU awards valued at the time of the respective awards at over 250%385% and 210%184% of base salary, respectively, subject in each case subject to time-based vesting over four years and continued employment. Equity awards for the other named executive officers ranged from 107% toour Group presidents on average approximated 155% of base salary, signifying strong alignment for our executive team with shareholderstockholder interests. Equity compensation comprised approximately 62% of our Chief Executive Officer's total direct compensation and approximately half of both the Chief Executive andour Chief Financial OfficersOfficer's total direct compensation, which includes base salary, annual bonus and long-term incentives. Long-term incentives as a percent of total direct compensation for our Group presidents also approximated half of their total direct compensation. Long-term incentives as a percent of total direct compensation for the other named executive officers as a group, including the CEO, ranged from 41%approximately 49% to 52%62%.




        The following charts and table illustrate the mix of base salary at approved 2017 levels, short-term cash incentive bonus at target levels and long-term incentive awards ("LTI") provided in the compensation packages of our Chief Executive Officer ("CEO"), and, on average, our named executive officers other than our Chief Executive Officer ("Other NEOs").

        For fiscal 2014,2017, the Compensation Committee approved a 9.1%5.2% salary increase for Dr. Laukien, our Chief Executive Officer. The Compensation Committee considered this adjustment appropriate based on the updated peer group data reviewed by the Compensation Committee, as Dr. Laukien's base salary and total compensation potential was, and after the increase continued to be, significantly below the market median for chief executive officers of the Company's compensation peer group.

The Compensation Committee considered this adjustment appropriate based on the updated peer group data and Mr. Mattacchione's performance evaluation.

        The Compensation Committee determined that, based on Dr. Munch's performance evaluation and the comparison to compensation paid to executives in comparable positions according to peer group and other market data reviewed by the Compensation Committee, Dr. Munch's base salary for fiscal 20142017 should be increased by 5.3%.

Cash Incentive Plans and Review of 20142017 Performance

        Annual cash incentive compensation supports the Compensation Committee's pay-for-performance philosophy and aligns individual goals with Company goals.those of the Company. Under the annual short-term incentive compensation plans, or ICPs, executive officers are eligible for cash awards based on a combination of the Company's attainment of pre-established financial performance metrics and achievement of specific individual qualitativeperformance goals. ConsistentWhile still measurable, individual performance goals may not always be as quantifiable as the financial objectives. Thus, and consistent with its past practice, the Compensation Committee structured our executive officers' 2014 cash incentive plans2017 ICPs as follows:

•

At the beginning of the fiscal year, the Compensation Committee established performance measures and goals, which included the financial and strategic metrics being assessed, performance thresholds and targets and weightings for each metric.



•

Also at the beginning of the fiscal year, the Compensation Committee set individual target awards for each executive officer, expressed as a percentage of base salary, based on the executive's level of responsibility and upon a review of management recommendations, compensation information from our peer group and survey market data for comparable positions.



•

Also at the beginning of the fiscal year, the Compensation Committee established performance measures and goals for the ICPs, which included the financial and strategic metrics being assessed, performance thresholds and targets and weightings for each metric. The Compensation Committee also approved the executive officers' individual performance goals.



•

After the close of the fiscal year, the Compensation Committee received a report from management regarding Company, operating Group and individual performance against the pre-established performance goals.goals of the ICPs. Actual awards for 20142017 were approved based on each named executive officer's individual award target percentage and the overall Company, Group and/or individual performance relative to the specific performance goal, as determined by the Compensation Committee.




        The Compensation Committee sets the performance metrics as well as the performance thresholds and targets for each metric after consultation with management. The two primary classifications of




performance goals utilized in the annual incentive plansICPs are quantitative financial goals and individual qualitative performance goals. Each performance metric represents part of the total incentive award calculation, with the quantitative financial goals accounting for, in the aggregate, 70% of the target award potential and the individual qualitative performance goals accounting for, in the aggregate, 30% of the total incentive award potential. Payments for cash incentive bonuses linked to the achievement of pre-established quantitativefinancial performance goals are calculated based on percentage achievement of the quantitativefinancial target goal. While there is no maximum payout for any individual quantitativesingle financial goal, total incentive award payouts, after combining both financial and qualitativeindividual portions, are subject to a maximum amount of 200% of the individual's incentive award target.

        Payments for individual qualitativeperformance goals are made in a range of 0% to 125%, with 50%based on evaluation of the target amount payable ifnamed executive officer's performance and determined by the Compensation Committee determines that a qualitative goal was partially achieved, 75% ofaccording to the target amount payable if the Compensation Committee determines that a qualitative goal was mostly achieved, 100% of the target amount payable if the Compensation Committee determines that a qualitative goal was substantially or completely achievedfollowing schedule:

        Individual qualitativeperformance goals are generally set as stretch but attainable goals, with over-achievement of goals anticipated to occur in very limited circumstances, such that only up to 15% of such goals may be awarded with payout of 125% for outstanding performance.circumstances. Additionally, the Compensation Committee may, in its discretion, award cash incentive bonuses above the target level in the event it determines that an executive officer has delivered exceptional performance. Effective in 2014, the cashCash incentive compensation plans of our named executive officers all operate under a common set of performance metrics and calculation methodologies, with goals adjusted at the Corporate or Group level to reflect individual areas of responsibility. Moreover, each Group president also has a portion of his financial quantitative goals tied to the overall profitability of the Company, creating additional alignment, unity of purpose and teamwork across the Company.

20142017 Cash Incentive Plans

        Setting Incentive Target Levels.    The Compensation Committee establishes cash incentive plansannual ICPs for our executive officers, including each of our named executive officers, which are designed to provide meaningful performance incentives, relative to both fixed cash compensation in the form of salary and overall potential cash compensation, consistent with the Company's strategic goals and objectives and each individual executive officer's responsibilities. The following table summarizes the 2014 cash incentive2017 ICP target levels approved for each of our named executive officers, other than Mr. Knell, and the relationship of performance-based cash compensation at target levels to base salary and total potential cash compensation. Mr. Knell resigned effective March 31, 2017 and was not eligible to participate in the 2017 ICP program.

        When setting individual target incentive levels for fiscal 2014,2017 ICPs, the Compensation Committee reviewed, for each named executive officer, individual target awards applicable in fiscal 2013,2016, the total cash compensation established for fiscal 20132016 and the projected cash compensation for fiscal 2014,2017, considering how the total cash compensation of each named executive officer compared to peer group and related market data, and the responsibilities of each named executive officer. Additionally, the Committee considered long-term incentive target levels, to take into account a total direct compensation view, so that no one element was determined in isolation, but rather the entire total compensation picture was considered. Based upon this review, as well as the increase in Dr. Laukien's 2014 base salary, the Compensation Committee determined that his cash incentive target should be adjusted to provide both a meaningful increase in his total cash compensation potential and to maintain an appropriate mix of short-term fixed and variable compensation. As a result, Dr. Laukien's cash incentive target was raised to $800,000 from $700,000, or to 133%should remain at 140% of base salary from 127% of base salary, which represented a modest increase in Dr. Laukien's relative amount of "at risk" potential cash compensation.pay. The Compensation Committee also determined that a greater amount of Mr. Srega'sMattacchione's potential cash compensation should be tied to performance incentives in light of his current responsibilities and therefore increased his cash incentive target to $204,743 from $185,948, or from 50%70% of base salary to 55%from 65% of base salary. Additionally,salary in light of2016. Finally, based on its review of peer group data and the overall compensation of each other named executive officer, the Compensation Committee determined to maintain the relative levels of Mr. Wagner'sSrega's and Dr. Munch's cash incentive targettargets for 2017 at 100%55% and 60% of base salary, for 2014. Given that Mr. Bachmann was new to the Company in August 2013, his compensation remained unchanged for fiscal 2014.respectively.

        Setting Performance Goals and Thresholds.    The Compensation Committee establishes specific Corporate level quantitative financial performance goals for our executive officers with corporate responsibilities, including named executive officers Dr. Laukien and Mr. Wagner,Mattacchione, and Group level quantitativefinancial performance goals for our executive officers with Group level management responsibilities, including Mr. Srega Mr. Bachmann and Dr. Munch, based on key Corporate, Group or divisional business plan goals for the fiscal year. In addition to goals tied to Group level financial performance, each of our Group Presidents has a portion of his incentive award potential linked directly to our profitability at the Corporate level, creating additional alignment with the overall strategic objectives of the Company. QuantitativeFinancial performance goals generally reflect targeted growth over the results achieved in the prior year for the relevant metric, with a threshold level of current year performance required for any cash incentive payout that is typically equal to the prior year performance. However, in the case of business plan goals for which only modest or no growth is forecast, performance thresholds may be set at 95% of the business plan goal, which may result in a performance threshold




that is less than the results achieved in the prior year. For example, because our 20142017 business plan included goals of less than 5% currency-adjusted revenue growth at the Corporate and Bruker CALID and Bruker Nano Group levels, the performance thresholds for Dr. Laukien's, Mr. Wagner's, Mr. Srega's and Dr. Munch's quantitativeour named executive officers' financial performance targets tied to revenue growth at the Corporate or Group level, as applicable, waswere set at approximately 95% of the relevant business plan goal. As a result, the threshold level of 20142017 revenue needed to earn any portion of their goals linked to revenue growth, on a currency-adjusted basis, was slightly below 20132016 results.

        For purposes of measuring Similarly, the performance threshold for our named executive officers' financial performance relativetied to their respective cash incentive plan financial objectives, it is our practice to exclude from our financial results the impact of significant one-time or extraordinary events, such as acquisitions or divestitures. Consistent with that practice and because during 2014 we decided to restructure the CAM division and exit or divest businesses relating to two of that division's three main product lines, the Compensation Committee determined that itincrease in non-GAAP EPS was appropriate to exclude the financial resultsset at 95% of the CAM division from our overall corporate financial results for 2013 and 2014 for purposesrelevant business plan goal. As a result, the threshold level of determining 2014 cash incentive payouts2017 non-GAAP EPS needed to earn any portion of their goals linked to Corporate level quantitative financial goals established for our executive officers. However, CAM division financial results were considered for purposes of determining Mr. Srega's Group level incentive award payout because, as President of the Bruker CALID Group, henon-GAAP EPS growth was responsible for the performance of the CAM division and also received in November 2014 a special cash incentive award in connection with his contributions to the asset sales completed as part of the CAM division restructuring.

        The following tables provide a summary of the specific Corporate level financial goals and performance thresholds established by the Compensation Committee for our executive officers' 2014 cash incentive plans, as well as the adjustments that were considered by the Compensation Committee for purposes of determining incentive award payouts for our executive officers' 2014 performance relative to these goals.

        For 2014,2017, the Compensation Committee established quantitative financial performance targets that represented 70% of each named executive officer's total incentive award target. The Corporate level goals for these executive officers emphasized key elements of our strategy for providing value to our stockholders, with a mix of goals that focus on generating revenue growth, improving efficiency and profitability, and working capital reduction. As summarized in the table above, Dr. Laukien and




Mr. Wagner partially achieved the currency-adjusted revenue growthwe did not achieve our Corporate level reduction in working capital goal, andbut significantly exceeded the working capital ratio improvement goaleach of the Company's 2014 business plan, which together accounted for 50% of the potential incentive award payment forour other Corporate level quantitative goals, but did not meet or exceed the threshold performance level for targeted non-GAAP operating profit or non-GAAP earnings per share improvements, resulting in no award earned for such goals. As a result of the challenges to the Company's financial performance in 2014 and consistentgoals. Consistent with our pay-for-performance philosophy, the cash incentives earned by Dr. Laukien and Mr. WagnerMattacchione for the quantitative financial performance portion of their 2014 cash incentive plans2017 ICPs was equal to approximately 76%177% of their cash incentive targets linked to quantitativefinancial performance goals, or approximately 53%124% of their respective total cash incentive targets.


Individual Performance Goals

The individual performance goals for Dr. Laukien's and Mr. Mattacchione's 2017 ICPs are described below.

Dr. Laukien

        The individual performance goals established by the Compensation Committee for Dr. Laukien's 2017 ICP were designed to measure and reward the achievement of objectives relating to strategic acquisition targets, continued strengthening and development of the senior management team, innovation in product development to drive organic revenue growth, tax planning and implementation of operational efficiency initiatives and management of the Bruker BioSpin Group leadership transition. The Compensation Committee assessed Dr. Laukien's performance relative to these individual performance goals and rewarded Dr. Laukien wasfor fully achieving his goals relating to strategic acquisition targets, management development, implementation of operational efficiency initiatives and management of the Bruker BioSpin Group leadership transition. The Compensation Committee also rewarded Dr. Laukien for mostly achieving goals linked to management development, as well as the Company's outsourcing and restructuring initiatives, new product innovation and divisionaltax planning initiatives. Consistent with this assessment of performance, in addition to partially achieving goalsDr. Laukien earned 90% of the portion of his cash incentive target linked to capital deployment.individual performance goals, or 27% of his total cash incentive target.

Mr. Mattacchione

        Mr. Mattacchione's individual performance goals were designed to measure and reward the achievement of goals relating to strengthening and increasing the effectiveness of the global finance and internal audit organizations, implementing process improvement initiatives and advancing systems improvements.

Section 162(m) Limitations

        Section 162(m) of the U.S. Internal Revenue Code limits the tax deductibility by a corporation of compensation in excess of $1,000,000 paid for any fiscal year to certain "covered employees." Prior to the U.S. tax reform legislation enacted in December 2017 ("2017 Tax Act"), covered employees generally consisted of our Chief Executive Officer and each of the next three highest compensated officers serving at the end of the taxable year other than our Chief Financial Officer, and compensation that qualified as "performance-based" under Section 162(m) was exempt from this $1 million deduction limitation if specific requirements were met. Under the 2017 Tax Act, this exemption for performance-based compensation will not be available with respect to taxable years beginning after December 31, 2017 unless the compensation is pursuant to a written binding contract which was in effect on November 2, 2017 and is not modified in any othermaterial respect on or after such date. Additionally, the 2017 Tax Act expanded the definition of its fourcovered employees to cover additional executive officers, including the chief financial officer, so that the compensation of the chief executive officer and chief financial officer (at any time during the fiscal year), and the three other most highly compensated executive officers. Compensation which qualifies as "performance-based" may qualify for exclusion fromofficers (as of the $1,000,000 limit if, among other requirements,end of any fiscal year) will be subject to Section 162(m) of the Code. Any executive officer whose compensation is payable only upon attainment of pre-established, objective performance goals under a plan approved by stockholders. Having considered the requirements of Section 162(m), the Compensation Committee believes that stock option grants to date meet the requirement that such grants be "performance-based" and are, therefore, exempt from the limitations on deductibility. Base salaries, awards under our executive officers' cash incentive plans, any other bonus payments and compensation in the form of restricted stock awards, however, are generally subject to Section 162(m) of the $1,000,000 limit on tax deductible compensation.Code in taxable years beginning after December 31, 2016 will have compensation subject to Section 162(m) of the Code for all future years, including years after the executive terminates employment or dies.

        The Compensation Committee and management consider the accounting and tax effects of various compensation elements when designing our annual incentive and equity compensation plans and making other compensation decisions. Although we have undertakenconsidered the impact of Section 162(m) when designing our executive compensation programs and incentive plans so that a number of awards may be granted under these plans and programs in a manner that complies with the requirements imposed by Section 162(m), tax deductibility is not the primary factor used by the Compensation Committee in setting compensation and likely will become less of a factor following the changes to qualify certain components of our incentive compensation to executive officers forSection 162(m) as provided in the performance exception to non-deductibility,2017 Tax Act. Rather, these considerations are secondary to meeting the overall objectives of the executive compensation program. The Compensation Committee will continue to monitor the compensation levels potentially payable under our compensation programs but intends to retain the flexibility necessary to provide total compensation in line with competitive practice and our compensation philosophy. Under certain circumstances,philosophy, even if such as the payment of cash bonus awards and the granting of restricted stock awards, the Committee may decide to award executive compensation in an amount and form that is not deductible under Section 162(m).




Other Benefit Plans

        In October 2009, the board of directors of BEST adopted the Bruker Energy & Supercon Technologies, Inc. 2009 Stock Option Plan, or the BEST Plan.

The BEST Plan allows a committee of the BEST board of directors to grant incentive stock options and non-qualified stock options to key employees and directors of the Company.

Pension Benefits


        Retirement Plan for Mr. Srega.    A personal pension scheme established for Mr. Srega's benefit, which was in part carried forward from his former employer, is funded by contributions made by Bruker Daltonik GmbH and voluntary contributions by Mr. Srega, if any, during the term of his employment. The personal pension scheme has three components: a contribution-based plan of Bruker Daltonik GmbH (the "Bruker Daltonik Plan"); a pension fund guarantee (the "Guarantee Plan"); and a cash value life insurance policy (the "Life Insurance Policy"). The Bruker Daltonik Plan provides for monthly Company contributions in the amount of €5,500€5,541 (approximately $80,223$6,638 per month or $79,656 per year) and a lifetime monthly retirement benefit based on the value of accumulated capital beginning at age 67 or a lump-sum payment. In the event of termination of employment or death prior to age 67, the Bruker Daltonik Plan provides for a reduced benefit to be determined based on the cash assets of the plan at such time. Mr. Srega may also elect to receive a reduced benefit beginning at age 62 in the event of early retirement. The Guarantee Plan provides an inflation hedge and an additional monthly retirement benefit, commencing December 1, 2019, with an annually increasing benefit based on Guarantee Plan earnings or, at Mr. Srega's election, a lump-sum payment. The Guarantee Plan is funded by annual Company contributions during the term of employment in amounts which increase annually by the same percentage as the upper earnings limit established under German law for pension insurance contributions. In the event of death prior to December 1, 2019, the Guarantee Plan provides for a lump-sum payment in an amount to be determined based on the plan assets at such time. In the event of death on or after December 1, 2019, benefits will terminate effective November 30, 2024. If Mr. Srega's employment terminates prior to the eligible retirement age, Mr. Srega may elect to continue funding through personal contributions or the Guarantee Plan may be transferred to a




subsequent employer. Under the Life Insurance Policy, which matures on November 1, 2019, Mr. Srega is entitled to receive at the earlier of death or maturity a payment in the amount €53,028 (approximately $64,455)$63,528), adjusted for increases in the value of accumulated surplus and reserves, if any. In the event Mr. Srega's employment terminates prior to the maturity date, other than by reason of




death, the Life Insurance Policy and continued funding obligations are to be transferred to Mr. Srega. Amounts payable in euros are converted to U.S. dollars at the average midpoint conversion rate of €1.0=$1.21551.1980 as of December 31, 2014.2017. Mr. Srega may also make voluntary contributions to the personal pension scheme during the term of his employment.

        Swiss Pension Plan.    As an employee of our BioSpin AG subsidiary in Switzerland, Mr. Bachmann is eligible to participate in a defined benefit plan available to all employees of our subsidiaries in Switzerland, which we refer to as the Swiss Pension Plan. Mr. Bachmann participates in the plan on the same terms and conditions as all other Swiss employees and does not receive any additional supplemental executive pension contributions. The Swiss Pension Plan is a cash balance based pension arrangement, under which we contribute an annual amount based on a percentage of salary and the participant's age. Employees may also make contributions based on a percentage of salary and age. Additionally, participants are allocated annual savings and interest credits based on age and account value, respectively. Payments to participants are based on accumulated capital in the participant's plan account and may be taken as a lump sum or annuity at normal retirement, beginning at age 65. Participants may also elect to receive a reduced benefit beginning at age 58 in the event of early retirement. In the event of premature death and disability, the Swiss Pension Plan also provides for payments in the form of an annuity based on a percentage of the participant's salary or as a lump-sum based on accumulated plan account assets.

        Information about our contributions to the personal pension scheme of Mr. Srega and the Swiss Pension Plan in which Mr. Bachmann is a participant is provided in the Summary Compensation Table above under the column entitled "All Other Compensation" and the related footnotes.

Potential Payments upon Termination or Change-in-Control


        The following information describes and quantifies certain compensation and benefits that would have been payable under existing agreements, plans, and arrangements if the named executive officer's employment had terminated on December 31, 2014,2017, given his compensation and service levels as of that date. These benefits are in addition to the benefits to which the named executive officer was already entitled or in which he was vested as of such date, as well as certain benefits that are generally available to salaried employees. Due to the number of factors that affect the nature and amount of the compensation and benefits potentially payable upon the events described below, any amounts actually




paid or distributed may be different than those shown in the table. Factors that could affect these amounts include the nature of or basis for such termination, the timing during the year of any such event, whether and when a named executive officer decides to exercise stock options and our stock price on that date and the exercise of discretion by the Board or Compensation Committee regarding the payment of compensation and benefits.

        Severance Benefits.    The cash severance benefits contained in the employment agreementsagreement for Messrs. Wagner andMr. Srega, and the amounts each of those named executive officershe would be paid in connection with (a) a termination of the executive officer's employment within six months of a change in voting control of the Company or (b) in the case of Mr. Wagner only, termination without cause, if such termination had occurred on December 31, 2014 are described in the Compensation and Discussion & Analysis section of this proxy statement under the heading "Employment Agreements,




Termination of Employment and Change in Control Arrangements." The separation arrangement and agreement provided for Mr. Knell are also described in that section of this proxy statement. Other than as contained in thosesuch agreements, we do not have arrangements with any of our other named executive officers, including Dr. Laukien, Mr. Mattacchione and Dr. Munch, and Mr. Bachmann, which provide cash severance benefits in the event of termination of employment or a change in control of the Company. Upon completion of his transition responsibilities, Mr. Knell received a payment of $116,573 in connection with the termination of his employment.

        Equity Awards.    The unvested equity awards held by each of the named executive officers as of December 31, 20142017 are described above in the 20142017 Outstanding Equity Awards table. We made eachEach of thosethe stock option and restricted stock awards granted prior to May 20, 2016 were granted pursuant to our 2010 Incentive Compensation Plan, or 2010 Plan. Each of the equity-based awards granted on or after May 20, 2016 were granted pursuant to our 2016 Plan. In accordance with that planthe terms of the 2010 Plan and the 2016 Plan and our related award agreements, except as noted below, no accelerated vesting of stock options or restricted stock awards would have occurred as of December 31, 20142017 in the event of a voluntary termination by a named executive officer or an involuntary termination by us, whether with or without cause. Generally, upon termination of employment, (a) any unvested restricted stock is forfeited and (b) the participant has a period of 90 days from termination to exercise any vested option awards (or, if earlier, until the option expiration date). However, in the event of termination for cause, including as a result of dishonesty with respect to the Company or any of its affiliates, breach of fiduciary duty, insubordination, substantial malfeasance or non-feasance of duty, unauthorized disclosure of confidential information, material failure or refusal to comply with Company's published policies generally applicable to all employees or conduct materially harmful to the business of the Company or any of its affiliates, all vested and unexercised options are forfeited immediately upon termination. Additionally, in the event of death or disability of a plan participant, including any named executive officer, (a) any unvested restricted stock will become vested and (b) all vested stock options will remain exercisable for a period of 90 days following such event (or, if earlier, until the stock option expiration date).

        The Compensation Committee has discretion to revise or amend outstanding equity awards and may, at its discretion, accelerate vesting of any unvested option or restricted stock awards, including in connection with a "Change in Control" of the Company, as defined in our 2010 Incentive Compensation Plan.Plan or 2016 Plan, as applicable. Under that plan,these plans, a "Change in Control" occurs if: (a) within one year of any merger, consolidation, sale of a substantial part of the Company's assets, or contested election, the persons who were directors of the Company immediately before such transaction cease to constitute a majority of the board of directors of the Company or its successor to the Company; (b) if, as a result of any such transaction, the Company does not survive as an entity, or its shares are changed into the shares of another corporation unless the stockholders of the Company immediately prior to the transaction own a majority of the outstanding shares of such other corporation immediately following the transaction; (c) any person or group who owned less than twenty percent of the outstanding common stock of the Company at the time of adoption of the 2010 Incentive Compensation Plan or 2016 Plan, as applicable, acquires ownership of fifty percent or more of the Company's outstanding common stock; (d) the dissolution or liquidation of




the Company is approved by its stockholders; or (e) the members of the board of directors as of the date the 2010 Incentive Compensation Plan or 2016 Plan, as applicable, was adopted cease to represent at least two-thirdstwo thirds of the Board, subject to certain exceptions.

        Additionally, with respect to awards granted pursuant to the 2016 Plan, in the event of a Change in Control, if (a) an award is assumed or continued (including through conversion or substitution for a substantially similar award of the successor) and, within twenty four (24) months following the Change in Control (or such shorter period as specified in the applicable award agreement), the executive officer's employment is terminated without cause or is voluntarily terminated for good reason (a "double-trigger" provision), or (b) an award is not assumed or continued, then any then outstanding awards of stock options will vest and become fully exercisable and any outstanding unvested awards of restricted stock units that are not performance-based will be treated as vested.

        Retirement Plans.    The retirement plansplan provided for Mr. Srega and Mr. Bachmann areis described under the heading "Pension Benefits" above. In the event of termination of employment as of December 31, 20142017 by reason of death, Mr. Srega's beneficiary would be entitled to receive an estimated lump-sum payment of $283,236,$521,488, which amount is payable in euros and converted to U.S. dollars based on the average midpoint conversion rate of €1.0 =$1.2155€1.0=$1.1980 as of December 31, 2014.2017.


PAY RATIO DISCLOSURE


        InAs required by Section 953(b) of the eventDodd-Frank Wall Street Reform Act and Consumer Protection Act of termination2010, and Item 402(u) of employmentRegulation S-K, we are providing the following disclosure about the ratio of the annual total compensation of Dr. Frank Laukien, our President and Chief Executive Officer (CEO), to the annual total compensation of our median employee.

        For 2017, our last completed fiscal year, the median of the annual total compensation of all employees of our Company (other than our CEO) was $72,517. The 2017 annual total compensation of our CEO, as reported in the Summary Compensation Table included in this proxy statement, was $4,872,009. Based on this information, for 2017 the ratio of our CEO's annual total compensation to the annual total compensation of our median employee was 67:1. This ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

        For purposes of reporting annual total compensation and the ratio of annual total compensation of the CEO to the median employee, both the CEO and median employee's annual total compensation




were calculated consistent with the disclosure requirements of executive compensation under the Summary Compensation Table.

        To identify the median employee, we examined the 2017 target total cash compensation, including annualized base salaries plus target performance bonus, incentive pay and commissions, for all individuals, excluding our CEO, who were employed by us as of DecemberOctober 31, 2014, other than2017, as reflected in our payroll records. In accordance with Item 402(u) and instructions thereto, we included all 6,125 full-time, part-time, temporary and seasonal employees. We selected target total cash compensation for reasonall employees as a consistently applied compensation measure because we do not widely distribute annual equity awards to employees and because we believe that this measure reasonably reflects the total annual compensation of death or disability, Mr. Bachmann would be entitled to receive a lump-sum paymentour employees. For purposes of vested benefitscalculating the target total cash compensation of our non-U.S. employees, we converted local currencies at the applicable 2017 average exchange rates as of October 31, 2017.

        Once we identified our median employee based on that analysis, we then determined that employee's total compensation in the amountsame manner that we determine the total compensation of $38,207. Inour named executive officers for purposes of the event of disabilitySummary Compensation Table, as of December 31, 2014, Mr. Bachmann would be entitled to receive an annual disability pension in the amount of $65,689. In the event of death, Mr. Bachmann's beneficiary would be entitled to estimated annual survivor benefits of $39,413. Amounts reported for Mr. Bachmann, which are payable in Swiss Francs, are converted to U.S. dollars based on the average midpoint conversion rate of CHF 1.0 =$1.0106 as of December 31, 2014.discussed above.


RELATED PERSONS TRANSACTIONS


Review and Approval of Transactions with Related Persons

        We have adopted a written Related Person Transactions Policy that prohibits transactions involving the Company and any related person, except in accordance with the policy. For purposes of this policy, related persons include (a) our executive officers, directors, director nominees or greater than 5% shareholders, or any of their immediate family members and (b) any firm, academic entity or other entity in which any of the foregoing persons is employed or is a partner or principal or in a similar position or in which such person has more than a 10% beneficial ownership interest. The Related Person Transactions Policy applies to any transaction or series of transactions, other than product or service sales or purchases entered into in the ordinary course of business involving aggregate amounts of less than $50,000 annually, in which the Company is a participant and in which any related person has a direct or indirect interest.

        Our Related Person Transactions Policy provides for standing pre-approval of certain categories of transactions with related persons, including:

•

transactions involving indebtedness for ordinary business travel and expense payments and similar indebtedness transactions arising in the ordinary course of business;



•

transactions in which a related person's interest arises solely from the ownership of a class of the Company's equity securities and in which all holders receive proportional benefits;



•

transactions involving compensation to executive officers approved by the Compensation Committee; and



•

transactions involving compensation to directors for services as a director of the Company.




        Under our Related Person Transactions Policy, any related person transaction not in one of the preceding categories must be submitted to our Chief Financial Officer for review and approval. Related person transactions involving amounts of $500,000 or less, as well as all product or service sales and purchases in the ordinary course of business, are subject solely to review and approval, ratification, amendment, termination or rescission by our Chief Financial Officer. Any transaction in excess of $500,000, other than a transaction involving product or service sales or purchases in the ordinary course of business, must be forwarded to the Audit Committee for review and approval, ratification, amendment, termination or rescission, at the discretion of the Audit Committee. In reviewing such transactions, our Chief Financial Officer or Audit Committee, as applicable, evaluates all material facts




relating to the transaction and takes into account, among other factors deemed appropriate, the related person's relationship to the Company and interest in the transaction, the terms of the transaction, including its aggregate value, whether the transaction is in the best interests of the Company, the impact on a director's independence in the event the related person is a director, a family member of a director, or an entity in which a director is a partner, shareholder or executive officer and, if applicable, the availability of other sources of comparable products or services and whether the transaction is on terms comparable to the terms available to an unrelated third party. Neither the Chief Financial Officer nor any member of the Audit Committee may participate in the review of any transaction involving such person or any of his or her immediate family members.

PROPOSAL NO. 2
ADVISORY VOTE ON EXECUTIVE COMPENSATION


        The Board of Directors recognizes the interest our stockholders have in the compensation of our executives. In recognition of that interest and as required by the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") and SEC rules, we are providing our stockholders the opportunity to cast a non-binding advisory vote on the compensation of our named executive officers, as disclosed pursuant to the compensation disclosure rules of the SEC.

        The compensation of our named executive officers is disclosed in the Compensation Discussion and Analysis, or "CD&A," the compensation tables, and the related disclosures contained in this Proxy Statement. As described in our CD&A, we have adopted an executive compensation philosophy designed to deliver competitive total compensation, upon the achievement of financial and/or strategic performance objectives, which will attract, motivate and retain leaders who will drive the creation of shareholder value. In order to implement that philosophy, the Compensation Committee has established a disciplined and rigorous process for the adoption of executive compensation programs and individual executive officer pay actions.

        We believe that our compensation policies and decisions are focused on pay-for-performance principles, are strongly aligned with the long-term interests of our stockholders, and provide an appropriate balance between risk and incentives. Stockholders are urged to read the CD&A section of this Proxy Statement, which discusses in greater detail how our compensation policies and procedures implement our executive compensation philosophy. We are asking our stockholders to indicate their support for our named executive officer compensation, as described in this Proxy Statement, by approval of the following resolution:

"RESOLVED, that the compensation paid to the Company's named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby APPROVED."

        Your vote on this Proposal No. 2 is advisory, and therefore not binding on the Company, the Compensation Committee, or the board of directors. The vote will not be construed to create or imply any change to the fiduciary duties of the Company or the board, or to create or imply any additional fiduciary duties for the Company or the board. The approval or disapproval of this proposal by stockholders will not require the Company's board of directors or the Compensation Committee to take any action regarding the Company's executive compensation practices. However, our board and our Compensation Committee value input from stockholders and will consider the outcome of the vote when making future executive compensation decisions.

The Board of Directors recommends a vote FOR the approval, on an advisory basis, of the 2017 compensation paid to the named executive officers, as disclosed in the Compensation Discussion and Analysis, the compensation tables, and related narratives in this Proxy Statement.





PROPOSAL NO. 3
RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


        PricewaterhouseCoopers LLP has been our independent registered public accounting firm since June 1, 2016, and has been selected by the Audit Committee of the board of directors as our independent registered public accounting firm for the fiscal year ending December 31, 2018. Although the Company is not required to seek stockholder approval of this appointment, the board of directors believes it to be sound corporate governance to do so. In the event that the stockholders fail to ratify the appointment, the Audit Committee will investigate the reasons for stockholder rejection and will reconsider the appointment. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent public accounting firm during the year if the Audit Committee believes that such a change would be in the best interests of the Company and its stockholders.

        A representative of PricewaterhouseCoopers LLP is expected to be present at the 2018 Annual Meeting and will have the opportunity to make a statement if he or she so desires to do so and will be available to respond to appropriate stockholder questions.

The Board of Directors recommends a vote FOR the ratification of the appointment of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm for fiscal 2018.





INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


        At a meeting held on June 1, 2016, the Audit Committee of the Company's Board of Directors approved the dismissal of Ernst & Young LLP ("Ernst & Young") as the Company's independent registered public accounting firm, effective June 1, 2016, and the appointment of PricewaterhouseCoopers LLP ("PwC") as the Company's independent registered public accounting firm, effective June 1, 2016, to perform independent audit services for the fiscal year ending December 31, 2016. During the fiscal years ended December 31, 2014 and 2015 and through June 1, 2016, neither the Company, nor anyone on its behalf, consulted PwC regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered with respect to the consolidated financial statements of the Company, and no written report or oral advice was provided to the Company by PwC that was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K and related instructions or a reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.

        The reports of Ernst & Young on the consolidated financial statements of the Company for each of the fiscal years ended December 31, 2015 and 2014 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

        In connection with the audits of our financial statements for each of the fiscal years ended December 31, 2015 and 2014, and in the subsequent interim period through June 1, 2016, there were no "disagreements" (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with Ernst & Young on any matter of accounting principles or practices, financial statement disclosure, or auditing scope and procedures, which, if not resolved to the satisfaction of Ernst & Young, would have caused Ernst & Young to make reference to the matter in their reports for such years. There were no "reportable events" as that term is described in Item 304(a)(1)(v) of Regulation S-K, except for a material weakness in the Company's internal control over financial reporting as of December 31, 2015 concerning the accounting for income taxes, which material weakness was identified subsequent to the filing of our Annual Report on Form 10-K for the year ended December 31, 2015.

        As a result of such material weakness, our management concluded in November 2016 that the Company's internal control over financial reporting was not effective at December 31, 2015. On November 15, 2016, the Company filed Amendment No. 1 to its Annual Report on Form 10-K for the fiscal year ended December 31, 2015, as well as amendments to each of its Quarterly Reports on Form 10-Q for the periods ended March 31, 2016, and June 30, 2016, to reflect the conclusion by management that there was a material weakness in internal control over financial reporting as of the end of the periods covered by those reports. The Company's Amendment No. 1 to its Annual Report on Form 10-K for the fiscal year ended December 31, 2015 also included revised auditor's reports from Ernst & Young stating that the Company's internal control over financial reporting at December 31, 2015 was not effective. During the year ended December 31, 2017, we remediated the material weakness in our internal controls over the accounting for income taxes.

Audit Committee Pre-Approval Policies and Procedures

        In order to ensure that audit and non-audit services proposed to be performed by the Company's independent registered public accounting firm do not impair the auditor's independence from the Company, the Audit Committee has adopted, and the board of directors has ratified, the following pre-approval policies and procedures.

Policies

        Before engaging the independent registered public accounting firm to render the proposed service, the Audit Committee must either (i) approve the specific engagement ("specific pre-approval") or (ii) enter into the engagement pursuant to pre-approval policies and procedures established by the Audit Committee ("general pre-approval"), provided the policies and procedures are detailed for the particular service, the Audit Committee is informed of each service, and such policies and procedures do not include delegation of the Audit Committee's responsibilities to management. The Audit Committee annually reviews and pre-approves the services that may be provided by the independent registered public accounting firm without obtaining specific pre-approval. The Audit Committee will add to or subtract from this list of general pre-approved services from time to time, based on subsequent determinations.

        Unless a type of service has received general pre-approval, it requires specific pre-approval by the Audit Committee if it is to be provided by the independent registered public accounting firm. Any proposed services exceeding pre-approved cost levels or budgeted amounts also require specific pre-approval by the Audit Committee.




        For both types of pre-approval, the Audit Committee considers whether such services are consistent with the SEC's and the PCAOB's rules on auditor independence. The Audit Committee also considers whether the independent registered public accounting firm is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with the Company's business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Company's ability to manage or control risk or improve audit quality. All such factors are considered as a whole, and no one factor will necessarily be determinative.

        The Audit Committee also considers the relationship between fees for audit and non-audit services in deciding whether to pre-approve any such services and may determine, for each fiscal year, the




appropriate ratio between the total amount of fees for Audit, Audit-related and Tax services and the total amount of fees for certain permissible non-audit services classified as All Other services.

        The Audit Committee may delegate either type of pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting.

Procedures

        Pre-approval fee levels or budgeted amounts for all services to be provided by the independent registered public accounting firm are established annually by the Audit Committee. Any proposed services exceeding these levels or amounts require specific pre-approval by the Audit Committee, even if previously generally pre-approved.

        All requests or applications for services to be provided by the independent registered public accounting firm that do not require specific approval by the Audit Committee are submitted to the Chief Financial Officer and must include a detailed description of the services to be rendered.

        Requests or applications to provide services that require specific approval by the Audit Committee must be submitted to the Audit Committee by both the independent registered public accounting firm and the Chief Financial Officer, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC's rules on auditor independence.

        The Audit Committee monitors the performance of all services provided by the independent auditor and assesses whether such services are in compliance with this policy.


PROPOSAL NO. 2
RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Although the Company is not required to seek stockholder approval of this appointment, the board of directors believes it to be sound corporate governance to do so. In the event that the stockholders fail to ratify the appointment, the Audit Committee will investigate the reasons for stockholder rejection and will reconsider the appointment. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent public accounting firm during the year if the Audit Committee believes that such a change would be in the best interests of the Company and its stockholders.

        The board will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Absent unusual circumstances or as contemplated by committee charters and subject to any required assistance or advice from legal counsel, Mr. Stein, the Secretary of the Company, is primarily responsible for monitoring communications from stockholders and for providing copies or summaries of such communications to the other directors as he considers appropriate.




        Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that Mr. Stein considers to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we may receive repetitive or duplicative communications.
