Fiscal 2020 Business Performance Highlights
At Mercury Systems, we deliver Innovation That Matters®. We make mission-critical technologies profoundly more accessible and affordable for aerospace and defense. Our fiscal 2020 results demonstrate that our customers trust us more than ever to meet their current and emerging technology and business needs. We delivered record bookings, revenue, net income, adjusted EBITDA, and adjusted EPS in fiscal 2020 against a challenging coronavirus backdrop. We continued to invest organically in the business for future growth, improved our performance in operations and manufacturing, acquired American Panel Corporation ("APC"), and concluded the year with zero debt and nearly $1 billion of financial capacity.
Our footprint has increased in recent years to more than 300 programs and platforms. Our top-line growth reflects this expansion. Revenue for fiscal 2020 increased 22% year-over-year to a new Company record of $797 million. Our largest revenue programs were SEWIP, F-35, P8, Filthy Buzzard and ARCI.
Organic revenue, excluding recent acquisitions, was up 14% from fiscal 2019. Bookings grew 22% to $954 million – our sixth straight record. Year-end backlog increased 33% to a record $831 million, positioning us to continue delivering above industry average growth in fiscal 2021. It was also a record year for new design wins, which amounted to more than $2 billion in total lifetime value.
Our business model continues to perform well, and Mercury delivered strong results on the bottom line in fiscal 2020. GAAP net income increased 83% from fiscal 2019, driven by improved operating performance and the positive impact of one-time, non-operating items. Adjusted EBITDA grew 21% to a record $176 million. It also was a record year for free cash flow, defined as operating cash flow less capital expenditures, at $72 million.
We are beginning fiscal 2021 in an excellent position strategically. The team is doing an outstanding job managing through the virus pandemic. Although the public health and economic risks remain elevated, we are positive about the business outlook.
We continue to believe that Mercury is targeting the right parts of the market. The wave of modernization occurring in radar, electronic warfare, and C4I continues to drive growth in the business. Demand in weapons systems, space, avionics processing, and mission computing, as well as secure rugged servers, remains healthy.
Our bookings and design win activity reflect the impacts of three industry trends that we have previously discussed: 1) supply chain delayering by the government and the defense primes; 2) the primes' flight to quality suppliers; and 3) increased outsourcing by the primes at the subsystem level. Potentially a fourth trend is the government's drive to create a domestic supply chain for secure and trusted advanced electronics capabilities designed and built in the U.S.
Protecting the health, safety and livelihoods of our employees has been the center of our decision making since the earliest days of the COVID pandemic. In return, our team has performed superbly in maintaining their productivity and overcoming our operational challenges.
We are optimistic about our ability to continue delivering organic revenue growth at a rate that exceeds the industry average, and confident that we can improve Mercury's financial performance by executing our plans in five areas:
deliver robust organic revenue growth, supplemented by growth from acquisitions;
invest in new technologies, in our manufacturing assets and business systems, and in our people;
enhance margins and drive working capital efficiencies through manufacturing insourcing and performance improvements;
create stronger operating leverage in the business by growing revenue faster than expenses; and
fully integrate our acquired businesses to generate cost and revenue synergies.
This strategy has worked very well over the past six years. Given our ability to execute, we are confident that Mercury will extend this record of success. We anticipate another year of strong growth in revenue and adjusted EBITDA in fiscal 2021, driven by high single-digit to low double-digit organic revenue growth, in line with our long-term strategy.

Executive Compensation Highlights and Alignment of Compensation with Business Strategy
Pay for Performance
Our executive compensation program is designed to motivate, engage, and retain a talented leadership team and to appropriately reward them for their contributions to our business. Our performance framework consists of a combination of financial performance measures that provide a balance between short-term results and drivers of long-term value. We provide our executive officers with three primary elements of pay: base salary; a performance cash bonus opportunity; and long-term equity incentive compensation. By placing a substantial majority of our executives' compensation at risk through performance-based variable compensation, we align our compensation program with our business strategy. The following charts show the pay mix for our CEO and our other named executive officers for fiscal 2020.
https://cdn.kscope.io/7f601bd32f59d091feb29d789a7507c4-chart12.jpg
        Performance-based variable compensation accounted for 88% and 79% of total compensation for our CEO and other named executive officers, respectively, for fiscal 2020. The foregoing percentages were calculated using the salary, annual cash bonuses, and the grant date fair value of equity awards as reported for fiscal 2020 in the Summary Compensation and Grants of Plan-Based Awards Tables below. All other compensation for our named executive officers for fiscal 2020, which consisted of a $12,000 allowance for tax and financial planning for executives, and a 401(k) match which is available to all employees, amounted to less than 1% of total compensation for named executive officers and is not reflected in the table above due to rounding.
Executive Bonus Program
For our fiscal 2020 executive bonus program, 100% of the total value was based on our achieving corporate financial performance objectives. Our fiscal 2020 executive bonus plan was split into two halves, with specific financial performance targets addressing the first half and the second half of the fiscal year. We used two semi-annual performance periods with two different performance targets in order to align our cash incentive program with our strategic operating plan ("SOP") review and midyear SOP update. We determined the potential total size of the annual cash incentive bonuses at the beginning of the fiscal year as well as set the first half financial performance target, and then set the second half and full year performance target in connection with our midyear SOP update. Potential over-achievement awards were based on exceeding the sum of the two half year corporate financial performance objectives. Our executive officers earned payouts at 100% of the first half target corporate financial performance bonus and 99% of the second half target corporate financial performance bonus. The target bonus was weighted 44% for the first half and 56% for the second half of the fiscal year, reflecting the fiscal 2020 adjusted EBITDA split between the first and second halves of the fiscal year in our SOP, with a catch-up feature for unearned first half cash incentives based on our full year performance. No over-achievement bonuses were earned for fiscal 2020. During the fourth quarter of fiscal 2020, we amended our adjusted EBITDA definition for external financial reporting to add back COVID-related costs as we believe these incremental expenses are outside the normal operations of the Company and are not indicative of ongoing operating results. The Compensation Committee maintained the original adjusted EBITDA target for the second half of the fiscal year and approved the use of the new adjusted EBITDA definition for the bonus plan for the second half of the fiscal year.
Executive Equity Awards
        Each fiscal 2020 restricted stock award for our named executive officers was 50% performance-based vesting and 50% time-based vesting. For the time-based vesting half of the fiscal 2020 awards, one-third vests on each of the first three anniversaries of the grant date. For the performance-based vesting half of the fiscal 2020 awards, the awards vest based on
v


relative performance to our peer group for the three-year period ending in fiscal 2022. For fiscal 2020, we used two relative performance metrics for the performance-based awards: (i) a ratio of adjusted EBITDA to revenue, percentile ranked relative to our peer group (50% weighting); and (ii) revenue growth percentage, percentile ranked relative to our peer group (50% weighting).
Our fiscal 2018 performance-based restricted stock awards vested at 250% based on our performance for the three-year period ended in fiscal 2020. Our fiscal 2018 performance awards used a mix of the ratio of adjusted EBITDA to revenue, percentile ranked relative to our peer group (75% weighting), and revenue growth percentage, percentile ranked relative to our peer group (25% weighting). Our financial results for the fiscal 2018 performance awards were at the 80th and 95th percentiles, respectively, of EBITDA margin and revenue growth compared to our peer group.
Compensation Governance and Best Practices
What We Do

Maintain a clawback policy for actions that result in a financial restatement
What We Don't Do
Provide gross-up payments to cover personal income taxes or excise taxes pertaining to executive or severance benefits
Allow employees, executives, and directors to engage in hedging or pledging of Mercury shares
Reward excessive, inappropriate, or unnecessary risk-taking
Allow the repricing or backdating of equity awards
Provide pension plans or supplemental executive retirement plans

Our CEO is a member of the Government Relations Committee as we believe his experience with our customers and markets adds value to the Committee.
        Our Board of Directors and executives understand and embrace the importance to all of our primary stakeholders of environmental, social, and governance ("ESG") measurement and reporting. For a number of years, we have been addressing the aspects of ESG we believe have the greatest impact on our business, our stakeholders, and value creation. As it relates to environment and sustainability, our initial priorities include: talent management and culture; responsible sourcing and operational excellence; cyber security; and environmental stewardship. We have also addressed a number of key governance principles that are considered best practice and will continue to advance in this area as well. Of our areas of focus, we are more advanced in developing talent management and culture and cyber security because these have the greatest potential to create - and the highest risk to destroy - value for Mercury and our shareholders. We are committed to continued progress in our efforts, results, and reporting accountability, and will add both to what we do and how we report these efforts over time.
        For talent management and culture, we invest in the professional development of our team members, hiring and retaining a diverse workforce. We are committed to ongoing employee training in critical compliance areas including business ethics, export rules, and our culture of integrity. We adhere to high ethical and security standards and operating with integrity is a foundation of our culture and values. We disclose in the Corporate Sustainability section of our website gender, racial, and ethnicity data, our voluntary and involuntary termination rates, and our OSHA injury rates.
Identifying and quantifying historic pay gaps based solely on gender can be challenging given the unique backgrounds each of our employees brings to the company. Despite this challenge and evidencing our strong commitment to closing the historical gender pay gap in the U.S., in 2018 we engaged an internationally known human resources consulting firm to conduct an assessment to determine the extent to which gender could have an impact on pay levels across the organization for our U.S. employees. That assessment found that women - without adjustment for factors outside of gender that might reasonably command higher pay in the marketplace from employers - are paid on average approximately 2% - 4% less than men. Based on the assessment, we have proactively worked to address each employee's individual circumstances to determine whether the pay gap was associated with factors other than gender and initiated a process to provide pay adjustments for women, as appropriate. Any adjustments have been based on the statistically derived recommendations from our outside consultant, and we continuously leverage market data and other statistics to inform promotions, adjustments, and new hire offers to provide women with competitive pay without regard to gender.
        The layers of cyber security we have built into our business systems and incorporated into our processes help ensure the critical data that drives the development of customer solutions is secure and protects our employees' personal information. Our good work has been recognized and we remain committed to modeling industry best practices. We have deployed and have been relying upon a best in class industrial security program as evidenced by superior ratings from the U.S. Defense Counterintelligence and Security Agency (DCSA). Four of our cleared sites have been recognized with the James S. Cogswell
viii


Industrial Security Achievement Award in recent years, with our Andover, MA headquarters being recognized with this award in 2020; less than 1% of the 13,000+ cleared contractor locations receive this award annually.
        Responsible sourcing and operational excellence are an integral part of value creation. We work with all our suppliers to ensure that we all adhere to an equal and high standard of sustainability and ethical principles. We provide opportunities for small businesses to engage with us as we support our customers in the aerospace, defense, and intelligence markets. We work closely with many categories of small businesses, including small disadvantaged, women-owned, veteran-owned, service-disabled veteran-owned, and historically underutilized business zone (HUBZone) companies.
        As a technology company, we have relatively limited exposure to environmental stewardship risks in our operations. We are committed to promoting environmental stewardship and introducing innovative processes and technologies that improve our efforts, including quantifying and disclosing our environmental impact along with our efforts to maximize future generations' ability to live, work, and play in our shared natural environment. We disclose in the Corporate Sustainability section of our website our energy and water usage at our U.S. facilities, including our scope 2 greenhouse gas (GHG) emissions for indirect emissions from the generation of purchased energy, as well as the GHG emissions from our business travel.
        Our executive leadership team reviews our ESG efforts and the Compensation Committee of the Board of Directors reviews our ESG practices with a view toward how our efforts help attract, develop, and retain employee talent, including our culture and values as well as how we demonstrate our commitment to good corporate citizenship.
Please see the Corporate Sustainability section of our website, www.mrcy.com, under "Who We Are" for detailed disclosures on our commitment to sustainability and ESG practices. Information contained on our website does not constitute part of this proxy statement or our annual report on Form 10-K.

What constitutes a quorum at the meeting?
The presence at the meeting, in person or represented by proxy, of the holders of a majority of our common stock outstanding on August 24, 2020, the record date, will constitute a quorum for purposes of the meeting. On the record date, 56,000,597 shares of our common stock were outstanding. For purposes of determining whether a quorum exists, proxies received but marked "abstain" and so-called "broker non-votes" (described below) will be counted as present.
How do I vote my shares?
Beneficial Shareholders. If you own shares through a broker, bank, or other holder of record (that is, your shares are held in "street name"), you must instruct the holder of record how to vote your shares. In order to provide voting instructions to the holder of record of your shares, please refer to the materials forwarded by your broker, bank, or other holder of record. If your shares are held in "street name" and you wish to vote them online at the meeting, you must obtain from your broker a properly executed legal proxy identifying you as a Mercury shareholder, authorizing you to act on behalf of the broker at the meeting, and specifying the number of shares with respect to which the authorization is granted. Proxies submitted by internet or telephone must be received by 11:59 p.m., Eastern Time, on October 27, 2020.
Registered Shareholders. If you own shares that are registered in your name, you may vote by proxy before the annual meeting by internet at www.envisionreports.com/MRCY, by calling 1-800-652-VOTE (8683), or by signing and returning your proxy card. To vote by internet or telephone, you will need your voting control number, which can be found on your proxy card. Proxies submitted by internet or telephone must be received by 11:59 p.m., Eastern Time, on October 27, 2020. If you return a signed proxy card but do not provide voting instructions for some or all of the matters to be voted on, your shares will be voted on all uninstructed matters in accordance with the recommendations of the Board.
If you sign, date, and return the proxy card but do not specify how your shares are to be voted, then your proxy will vote your shares as follows:
FOR the election of the nominees for three Class II directors and one Class III director named below under "Proposal 1: Election of Three Class II Directors and One Class III Director;"
FOR the approval of, on an advisory basis, the compensation of our named executive officers as disclosed in this proxy statement;
FOR the approval of our amended and restated 2018 Stock Incentive Plan;
FOR the approval of our amended and restated 1997 Employee Stock Purchase Plan;
2


FOR the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for fiscal 2021; and
in the proxy's discretion as to any other business which may properly come before the meeting or any adjournment or postponement of the meeting.
What discretion does my broker have to vote my shares held in "street name"?
A broker holding your shares in "street name" must vote those shares according to any specific instructions it receives from you. If specific instructions are not received, your broker may vote your shares in its discretion, depending on the type of proposal involved. Under applicable rules, there are certain matters on which brokers may not vote without specific instructions from you, such as the election of directors, the advisory vote on say-on-pay, and the approval of our equity plans. If such matters come before the meeting and you have not specifically instructed your broker how to vote your shares, your shares will not be voted on those matters, giving rise to what is called a "broker non-vote." Shares represented by broker non-votes will be counted for purposes of determining the existence of a quorum for the transaction of business, but for purposes of determining the number of shares voting on a particular proposal, broker non-votes will not be counted as votes cast or shares voting.
Can I change my vote after I return my proxy card?
Beneficial Shareholders. Beneficial shareholders should contact their broker, bank, or other holder of record for instructions on how to revoke their proxies or change their vote.
Registered Shareholders. Registered shareholders may revoke their proxies or change their voting instructions at any time before 11:59 p.m., Eastern Time, on October 27, 2020, by submitting a proxy via internet, telephone, or mail that is dated later than the original proxy or by delivering written notice of revocation to our Corporate Secretary. Registered shareholders may also revoke their proxies or change their vote by attending the virtual annual meeting and voting by ballot.
Your attendance at the virtual meeting will not be deemed to revoke a previously delivered proxy unless you clearly indicate at the meeting that you intend to revoke your proxy and vote online at the meeting.
How are votes counted?
Election of directors. A director nominee receiving a majority of the votes properly cast at the meeting for the nominee's election (meaning he or she receives more votes cast "FOR" than cast "WITHHOLD") will be elected director. Abstentions and broker non-votes, which are described above, will have no effect on the outcome of voting on these matters.
All other proposals. All of the other proposals at the meeting require the favorable vote of a majority of the votes cast on the matter. Abstentions and broker non-votes, which are described above, will have no effect on the outcome of voting on these matters.
How is Mercury soliciting proxies?
We bear the cost of preparing, assembling, and mailing the proxy material relating to the solicitation of proxies by the Board of Directors for the meeting. In addition to the use of the mails, certain of our officers and regular employees may, without additional compensation, solicit proxies in person, by telephone, or by other means of communication. We will also request brokerage houses, custodians, nominees, and fiduciaries to forward copies of the proxy material to those persons for whom they hold shares, and will reimburse those record holders for their reasonable expenses in transmitting this material.

Who sits on the Board of Directors?
Our by-laws provide for a Board of Directors of not fewer than three nor more than fifteen directors. As permitted by Massachusetts law, the Board of Directors is divided into three classes, with each class consisting, as nearly as may be possible, of one-third of the whole number of the Board of Directors. The Board of Directors currently consists of nine members, with James K. Bass, Michael A. Daniels, and Lisa S. Disbrow serving as Class I directors, Mark Aslett, Mary Louise Krakauer, and William K. O'Brien serving as Class II directors, and Orlando P. Carvalho, Barry R. Nearhos, and Vincent Vitto serving as Class III directors.
The terms of the Class I, Class II, and Class III directors expire in 2022, 2020, and 2021, respectively. With the expiration of its respective term, each class is nominated for election for a subsequent three-year term. We are proposing that the Class II nominees listed below, which consist of three incumbent directors, Mark Aslett, Mary Louise Krakauer, and William K. O'Brien, be elected to serve terms of three years and that the Class III nominee, Orlando P. Carvalho, an incumbent director, be elected to serve a term of one year, and in each case until their successors are duly elected and qualified or until they sooner die, resign, or are removed. Pursuant to our Board Policy, a director elected to the Board other than at a meeting of shareholders shall stand for election at the next shareholder meeting; accordingly, Mr. Carvalho is standing for election at this annual meeting as he was elected by the Board of Directors in January 2020.
Directors' Qualifications and Diversity
The Board of Directors believes that the Board, as a whole, should possess a combination of skills, professional experience, and backgrounds necessary to oversee the Company's business. In addition, the Board of Directors believes that there are certain attributes that every director should possess, as reflected in the Board's membership criteria. Accordingly, the
4


Board of Directors and the Nominating and Governance Committee consider the qualifications of directors and director candidates individually and in the broader context of the Board of Directors' overall composition and the Company's current and future needs.
The Nominating and Governance Committee is responsible for developing and recommending Board of Director membership criteria to the Board for approval. The criteria include independent and sound judgment, integrity, the ability to commit sufficient time and attention to Board of Director activities, and the absence of conflicts with the Company's interests. In addition, the Nominating and Governance Committee periodically evaluates the composition of the Board of Directors to assess the skills and experience that are currently represented on the Board of Directors as well as the skills and experience that the Board of Directors will find valuable in the future, given the Company's current situation and strategic plans. While the Nominating and Governance Committee does not have an explicit policy with respect to diversity, it may consider the Board's diversity of qualifications in terms of industry experience, functional skills, age, gender, race, ethnicity, governance service on other boards, prior work experience, educational background, and other important considerations. The Nominating and Governance Committee believes that it is important that Board of Director members represent diverse viewpoints and perspectives in their application of judgment to Company matters. In evaluating director candidates, and considering incumbent directors for renomination to the Board of Directors, the Nominating and Governance Committee considers, among other things, each nominee's independence, financial literacy, personal and professional accomplishments, and experience, including the following:

CORPORATE GOVERNANCE

Our CEO is a member of the Government Relations Committee as we believe his experience with our customers and markets adds value to the Committee.
Independence
The Board of Directors has determined that a majority of the members of the Board should consist of "independent directors," determined in accordance with the applicable listing standards of the Nasdaq Global Select Market as in effect from time to time. Directors who are also Mercury employees are not considered to be independent for this purpose. For a non-employee director to be considered independent, he or she must not have any direct or indirect material relationship with Mercury. A material relationship is one which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In determining whether a material relationship exists, the Board considers, among other things, the circumstances of any direct compensation received by a director or a member of a director's immediate family from Mercury, any professional relationship between a director or a member of a director's immediate family and Mercury's outside auditors, any participation by a Mercury executive officer in the compensation decisions of other companies employing a director or a member of a director's immediate family as an executive officer, and commercial relationships between Mercury and other entities with which a director is affiliated (as an executive officer, partner, or controlling shareholder). The Board has determined that directors who serve on the Audit Committee must qualify as independent under the applicable rules of the Securities and Exchange Commission ("SEC"), which limit the types of compensation an Audit Committee member may receive directly or indirectly from Mercury and require that Audit Committee members not be "affiliated persons" of Mercury or its subsidiaries. In addition, the Board of Directors has determined that directors who serve on the Compensation Committee must satisfy the standards for being considered a "non-employee director" within the meaning of Securities and Exchange Commission Rule 16b-3 and an "outside director" for purposes of Section 162(m) of the Internal Revenue Code.
Consistent with these considerations, the Board has determined that all of the members of the Board are independent directors, except Mr. Aslett, who is Mercury's President and Chief Executive Officer.
How are nominees for the Board selected?
Our Nominating and Governance Committee is responsible for identifying and recommending nominees for election to the Board. The Committee will consider nominees recommended by a shareholder if the shareholder submits the nomination in compliance with applicable requirements. The Committee did not receive any shareholder nominations for election of directors at this year’s meeting. With respect to the nominees for Class II director standing for election at the meeting, Ms. Krakauer and Messrs. Aslett and O'Brien were each most recently elected as a Class II director at the 2017 Annual Meeting of Shareholders.
14


With respect to the nominee for Class III director standing for election at the meeting, Mr. Carvalho was elected to the Board at a special Board of Directors meeting held in January 2020.
When considering a potential candidate for membership on the Board, the Nominating and Governance Committee will consider any criteria it deems appropriate, including, among other things, the experience and qualifications of any particular candidate as well as such candidate's past or anticipated contributions to the Board and its committees. At a minimum, each nominee is expected to have high personal and professional integrity and demonstrated ability and judgment, and to be effective, with the other directors, in collectively serving the long-term interests of our shareholders. In addition to these minimum qualifications, when considering potential candidates for the Board, the Committee seeks to ensure that the Board is comprised of a majority of independent directors and that the committees of the Board, other than the Government Relations Committee, are comprised entirely of independent directors. The Nominating and Governance Committee may also consider any other standards that it deems appropriate, including whether a potential candidate has direct experience in our industry and whether such candidate, if elected, would assist in achieving a mix of directors that represents a diversity of backgrounds and experiences. In practice, the Committee generally will evaluate and consider all candidates recommended by our directors, officers, and shareholders. The Committee intends to consider shareholder recommendations for directors using the same criteria that would be used with potential nominees recommended by members of the Committee or others.
Shareholders who wish to submit director candidates for consideration should send such recommendations to our Secretary at our executive offices not less than, unless a lesser time period is required by applicable law, 120 days nor more than 150 days prior to the anniversary date of the immediately preceding annual meeting of stockholders or special meeting in lieu of an annual meeting. Such recommendations must include the following information as to each person whom the shareholder proposes to nominate for election or reelection as a director:
the name and address of the shareholder and each of his or her nominees;
a description of all arrangements or understandings between the shareholder and each such nominee;
such other information as would be required to be included in a proxy statement soliciting proxies for the election of the nominees of such shareholder; and
the consent of each nominee to serve as a Director if so elected.
In addition, such recommendations must include the following information as to each shareholder giving the notice:
the number of all shares of Mercury stock held of record, owned beneficially (directly or indirectly) and represented by proxy by such shareholder as of the date of such notice and as of one year prior to the date of such notice;
a description of all arrangements or understandings between such shareholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by such shareholder;
a description of any derivative position held or beneficially held (directly or indirectly) by such shareholder with respect to Mercury stock;
a description of any proxy, contract, arrangement, understanding, or relationship between such shareholder and any other person or persons (including their names and addresses) in connection with the nomination or nominations to be made by such shareholder or pursuant to which such shareholder has a right to vote any Mercury stock; and
a description of any proportionate interest in Mercury stock or derivative positions with respect to Mercury held, directly or indirectly, by a general or limited partnership in which such shareholder is a general partner or, directly or indirectly, beneficially owns an interest in such a general partner.
We may require any proposed nominee to furnish such other information as may reasonably be required by us to determine the eligibility of such proposed nominee to serve as a director. Shareholders must also submit any other information regarding the proposed director candidate that is required to be included in a proxy statement filed pursuant to SEC rules. See also the information contained elsewhere in this proxy statement under the heading "Shareholder Proposals for the 2021 Annual Meeting."
Can I communicate with Mercury’s directors?
Yes. Shareholders who wish to communicate with the Board or with a particular director may send a letter to Mercury Systems, Inc., 50 Minuteman Road, Andover, Massachusetts 01810, attention: Secretary. The mailing envelope should contain a clear notation that the enclosed letter is a "Shareholder-Board Communication" or "Shareholder-Director Communication." All such letters should clearly state whether the intended recipients are all members of the Board or certain specified individual directors. Our Secretary will make copies of all such letters and circulate them to the appropriate director or directors.
15


What committees has the Board established?
The Board of Directors has standing Audit, Compensation, Nominating and Governance, M&A and Finance, and Government Relations Committees. As described above under the heading "Independence," all of the members of the Audit, Compensation, Nominating and Governance, and M&A and Finance Committees are deemed to be independent directors. Each of our Board committees acts under a written charter, copies of which can be found on our website at www.mrcy.com on the "Investor Relations" page under "Corporate Governance."
Audit Committee
The Audit Committee assists the Board in its oversight of management's conduct of our accounting and financial reporting processes, including by providing oversight with respect to the financial reports and other financial information provided by our systems of internal accounting and financial controls, and the annual audit of our financial statements. The Audit Committee also reviews the qualifications, independence, and performance of our independent registered public accounting firm, pre-approves all audit and non-audit services provided by such firm and its fees, and discusses with management and our independent registered public accounting firm the quality and adequacy of our internal control over financial reporting. The Audit Committee is directly responsible for the appointment, compensation, retention, and oversight of the work of our independent registered public accounting firm, which reports directly to the Audit Committee. The Audit Committee also is responsible for reviewing and approving related-person transactions in accordance with our Code of Business Conduct and Ethics and the Audit Committee charter.
Compensation Committee
The Compensation Committee is responsible for:
setting the compensation of our executive officers;
reviewing and approving employment agreements, consulting arrangements, severance or retirement arrangements, and change-in-control arrangements or provisions covering any of our current or former executive officers;
overseeing the administration of our equity-based and other long-term incentive plans;
exercising any fiduciary, administrative, or other function assigned to the committee under any of our health, benefit, or welfare plans, including our 401(k) retirement savings plan;
reviewing the compensation and benefits for non-employee directors and making recommendations for any changes to our Board;
overseeing the development and implementation of succession planning for our senior executives; and
reviewing our ESG practices with a view toward how our efforts help attract, develop, and retain employee talent, including our culture and values as well as how we demonstrate our commitment to good corporate citizenship.
All of the independent directors on the Board annually review and approve our CEO's corporate financial performance objectives, and evaluate the CEO's performance in light of those goals and objectives. Based on the foregoing, the Compensation Committee sets the CEO's compensation, including salary, target bonus, bonus and over-achievement payouts, and equity-based compensation, and any other special or supplemental benefits, which is then subject to ratification by a majority of the independent directors on our Board. Our CEO annually evaluates the contribution and performance of our other executive officers and provides input to the Compensation Committee, and the Compensation Committee sets their compensation. Our Senior Vice President, Chief Human Resources Officer and the Compensation Committee’s independent compensation consultant also make recommendations to the Compensation Committee regarding compensation for our executives.
The Compensation Committee may delegate to the Chief Executive Officer, the Chief Financial Officer, the General Counsel, and the Chief Human Resources Officer the authority to grant equity awards under our 2018 Stock Incentive Plan to individuals who are not subject to the reporting and other requirements of Section 16 of the Exchange Act. The Compensation Committee may also delegate the administration of the health, benefit, and welfare plans within the scope of its oversight to our human resources and finance departments and to outside service providers, as appropriate.
16


The Compensation Committee's independent compensation consultant provides input to the Compensation Committee regarding compensation for non-employee directors. The Compensation Committee then recommends any changes in the compensation and benefits for non-employee directors to the full Board for its consideration and approval.
The Compensation Committee is authorized to obtain advice and assistance from independent compensation consultants, outside legal counsel, and other advisors as it deems appropriate, at our expense. The Compensation Committee has engaged an outside compensation consultant, which has been Mercer since 2018, to assist the Committee in applying our compensation philosophy for our executive officers and non-employee directors, analyzing current compensation conditions in the marketplace generally and among our peers specifically, and assessing the competitiveness and appropriateness of compensation levels for our executive officers. Representatives of Mercer periodically attend meetings of the Compensation Committee, both with and without members of management present, and interact with members of our human resources department with respect to its assessment of the compensation for our executive officers. In addition, at the direction of the Compensation Committee, Mercer may assist management in analyzing the compensation of our non-executive employees. Mercer's services also include providing compensation survey data for non-employee directors, executives, and non-executive employees. Information regarding fees paid to Mercer can be found in the Compensation Discussion & Analysis section of this proxy statement under "How We Determine Executive Compensation".
Nominating and Governance Committee
The Nominating and Governance Committee assists the Board in identifying individuals qualified to become Board members, and recommends to the Board persons to be nominated for election as directors by the shareholders at the annual meeting of shareholders or by the Board to fill vacancies. The Committee has recommended the nominees for election at the annual meeting. In addition, the Committee oversees the process by which the Board and Committees each assesses its effectiveness as well as the individual director peer assessment process. The Committee also reviews our Board of Directors Policy and the charters for each of the Committees of the Board of Directors.
M&A and Finance Committee
The M&A and Finance Committee assists the Board in reviewing and assessing M&A transactions. The Committee is comprised of at least three members, all independent directors, as appointed by the Board. The Board has delegated to the Committee the authority to approve the acquisition or disposition of any other company, or any division, business unit or line of business of Mercury, for a purchase price of up to $25 million. The Committee also serves as the pricing committee for any of the Company's capital markets activities.
Government Relations Committee
The Government Relations Committee, consisting of three or more members as appointed by the Board, assists the Board with the following functions:
identifying and evaluating global security, political, budgetary, regulatory and other issues, trends, opportunities, and challenges that could impact our business activities and performance;
making recommendations to continue to raise our visibility in the marketplace and awareness of our commercial business model, as well as our products and capabilities; and
making recommendations concerning our government relations activities, including our interactions with local, state, and federal government on matters of impact to our business with the aim of enhancing our customer base.
In carrying out its duties and responsibilities, the Government Relations Committee has the authority to meet with and make inquiries of our employees as well as obtain advice and assistance from external advisors.

Number of Meetings During Fiscal 202097323
(1) The Board has determined that each of Messrs. Bass, Nearhos, and O’Brien and Ms. Disbrow qualified as an "audit committee financial expert" under Securities and Exchange Commission rules.
All of the directors attended at least 75% of the meetings of the Board of Directors and committees of the Board on which they served.
Our independent directors regularly meet in executive sessions outside the presence of management. The independent directors met four times during the last fiscal year in executive session without management present. All meetings, or portions of meetings, of the Board at which only independent directors were present were presided over by Mr. Vitto, our Chairman of the Board.
Does Mercury have a policy regarding director attendance at annual meetings of the shareholders?
Directors are encouraged to attend the annual meeting of shareholders, or special meeting in lieu thereof; however, we do not have a formal policy with respect to attendance at shareholder meetings. All of the directors then in office attended the 2019 annual meeting of shareholders.
Does Mercury have stock ownership guidelines for directors?
Each non-employee director is expected to own or control, directly or indirectly, shares of the Company's common stock equal to five times the value of the annual director cash retainer within five years of first becoming a non-employee director. Each non-employee director is expected to retain such investment in the Company as long as he or she is a non-employee director. Exceptions to this stock ownership guideline may be approved from time to time by the Board as it deems necessary to address individual circumstances.
Does Mercury have stock ownership guidelines and holding requirements for its Chief Executive Officer?
The CEO is expected to own or control, directly or indirectly, shares of Mercury common stock with a value of at least five times the CEO's base salary. The CEO is expected to meet this guideline within five years of first becoming CEO and is expected to retain such investment in the Company as long as he or she is the CEO. Prior to meeting the five times holding requirement per this guideline, after applicable tax withholding on the vesting of an equity award, the CEO is required to retain 50% of the net, after tax award until he or she is in compliance with the stock ownership guideline. Exceptions to this stock ownership guideline may be approved from time to time by the Board as it deems necessary to address individual circumstances. Mr. Aslett's holdings of our common stock satisfy the stock ownership guidelines.


18


Does Mercury have stock ownership guidelines and holding requirements for its executives who report to the Chief Executive Officer?
Each of the executives who report directly to the CEO is expected to own or control, directly or indirectly, shares of the Mercury common stock with a value of at least three times the individual's base salary. Each such executive is expected to meet this guideline within five years of first becoming a direct report to the CEO, or within five years of January 22, 2019, whichever is later. Each such executive is expected to retain such investment in the Company as long as he or she is a direct report to the CEO. Prior to meeting the three times holding requirement per this guideline, after applicable tax withholding on the vesting of an equity award, the executive is required to retain 50% of the net, after tax award until he or she is in compliance with the stock ownership guideline. Exceptions to this stock ownership guideline may be approved from time to time by the Board as it deems necessary to address individual circumstances. Each of our executive's holdings of our common stock satisfy the stock ownership guidelines.
Does Mercury have a Code of Business Conduct and Ethics?
Yes. We have adopted a Code of Business Conduct and Ethics applicable to our officers, directors, and employees. This code is posted on our website at www.mrcy.com on the "Investor Relations" page under "Corporate Governance." We intend to satisfy our disclosure requirements regarding any amendment to, or waiver of, a provision of our Code of Business Conduct and Ethics by disclosing such matters on our website.
Does Mercury have a Human Rights Policy?
Yes. We have adopted a Human Rights Policy applicable to our employees and our suppliers. Our Human Rights Policy is posted on our website at www.mrcy.com on the "Investor Relations" page under "Corporate Governance." This Policy goes beyond mere compliance with law. When differences arise between standards and legal requirements, the stricter standard applies, in compliance with applicable law. We also expect our employees and suppliers to conduct themselves in accordance with all other Mercury policies, including the Code of Business Conduct and Ethics.
Does Mercury have a Supplier Code of Conduct?
Yes. We have adopted a Supplier Code of Conduct. Our Supplier Code of Conduct is posted on our website at www.mrcy.com. Our Supplier Code establishes minimum expectations and requirements for suppliers, as well as their employees, subcontractors, and agents in connection with their business dealings with Mercury. We encourage suppliers to go beyond the principles outlined in the Supplier Code and to observe the highest international standards. If a matter is not expressly addressed in the Supplier Code, we expect suppliers to use good judgment and respect the spirit of the Supplier Code.
Does Mercury have a method for the anonymous reporting of accounting, legal, and ethical concerns?
Yes. Our Code of Business Conduct and Ethics, our Human Rights Policy, and our Supplier Code of Conduct each include a means for the anonymous reporting of any concerns about accounting, legal, and ethical matters. Any employee, supplier, customer, shareholder, or other interested party can submit a report via the following anonymous methods:
by telephone voicemail at 866-277-5739; or
by submitting a complaint via the internet at www.whistleblowerservices.com/mrcy.
Does Mercury have a written policy governing related-person transactions?
Yes. We have adopted a written policy which provides for the review and approval by the Audit Committee of transactions involving Mercury in which a related person is known to have a direct or indirect interest and that are required to be reported under Item 404(a) of Regulation S-K promulgated by the SEC. For purposes of this policy, a related person includes: (1) any of our directors, director nominees, or executive officers; (2) any known beneficial owner of more than 5% of any class of our voting securities; or (3) any immediate family member of any of the foregoing. In situations where it is impractical to wait until the next regularly scheduled meeting of the Audit Committee or to convene a special meeting of the Committee, the Chair of the Committee has been delegated authority to review and approve related-person transactions. Transactions subject to this policy may be pursued only if the Audit Committee (or the Chair of the Committee acting pursuant to delegated authority) determines in good faith that, based on all the facts and circumstances available, the transactions are in, or are not inconsistent with, the best interests of Mercury and our shareholders.

19


Does Mercury make corporate political contributions?
No, we do not use corporate funds for political contributions. If we were to use corporate funds for political activities, per our Code of Business Conduct and Ethics, any such contribution would require approval by the Board of Directors.
Does Mercury have a clawback policy?
Yes. We have adopted a clawback policy applicable to our executive officers. This policy is posted on our website at www.mrcy.com on the "Investor Relations" page under "Corporate Governance." Pursuant to our policy, the Board of Directors shall, in all appropriate circumstances, require reimbursement of any annual incentive payment or long-term incentive payment to an executive officer where: (1) the payment was predicated upon achieving certain financial results that were subsequently the subject of a substantial restatement of Company financial statements filed with the SEC; (2) the Board determines the executive engaged in intentional misconduct that caused or substantially caused the need for the substantial restatement; and (3) a lower payment would have been made to the executive based upon the restated financial results.
Does Mercury have a short sale and hedging policy?
Yes. Pursuant to our insider trading policy, no employee, executive officer, or director may at any time sell any securities of Mercury that are not owned by such person at the time of the sale. Also, no such employee, executive officer, or director may buy or sell puts, calls, or other derivative securities of Mercury at any time. In addition, no such employee, executive officer, or director may hold Mercury securities in a brokerage margin account.
Does Mercury have a shareholder rights agreement?
No, Mercury does not have a shareholder rights agreement or other "poison pill".
Does Mercury regularly engage with its shareholders?
Yes, corporate governance is a focus at Mercury. Our executive officers and the Board believe that shareholder engagement is an important component of our governance practices. We engage with shareholders on a variety of matters, such as corporate governance, executive compensation, and sustainability and have been responsive to the feedback provided by shareholders. Our shareholder engagement program is a year-round process that includes our annual investor day, our regular participation at investment conferences, and our engagement with shareholders on non-deal roadshows at which our executives regularly meet with shareholders.
How Does the Board of Directors Exercise Its Oversight of Risk?
Our Chief Executive Officer and senior management are principally responsible for risk identification, management, and mitigation. Our senior management engages in an enterprise risk management ("ERM") process each fiscal year. The process consists of an annual assessment of risks and an ongoing review of risk mitigation efforts and assessment of new risk developments. At regularly scheduled Board meetings, our Senior Director of Internal Audit reviews the key risks identified in the ERM process and management's plans for mitigating such risks. Our directors have the opportunity to evaluate such risks and mitigation plans, to ask questions of management regarding those risks and plans, and to offer their ideas and insights to management as to these and other perceived risks and the implementation of risk mitigation plans.
In addition to discussions at regular Board meetings, the Audit Committee focuses on risks related to accounting, internal controls, financial and tax reporting, and related-party transactions; the Compensation Committee focuses on risks associated with our executive compensation policies and practices and executive succession planning; the Nominating and Governance Committee focuses on risks associated with non-compliance with SEC and Nasdaq requirements for director independence and the implementation of our corporate governance policies; the M&A and Finance Committee focuses on risks related to our acquisition activities; and the Government Relations Committee focuses on risks to our business from governmental actions, including the defense budget and continuing budget resolutions.
How is the Leadership of the Board of Directors Structured and How Does this Leadership Structure Impact Risk Oversight?
Our Board Policy provides that the Chairman of the Board will be elected from among the independent directors, barring the Board's specific determination otherwise. If, in its judgment the Board determines that election of a non-independent Chairman would best serve the Company at a particular time, such a Chairman would be excluded from executive sessions of
20


the independent directors. In such case, a Lead Independent Director, as appointed from time to time, would preside over executive sessions and would perform such other duties as might be determined from time to time by the Board.
The Board has determined that having a separate Chairman and Chief Executive Officer is the most appropriate leadership structure for the Board of Directors at this time. However, the roles of Chairman and CEO may be filled by the same or different individuals. This allows the Board of Directors flexibility to determine whether the two roles should be combined in the future based upon the Company's needs and the Board of Directors’ assessment of the Company’s leadership from time to time.
As discussed above, our Chief Executive Officer and senior management are principally responsible for risk identification, management, and mitigation through our ERM process. Our Chairman of the Board is responsible for providing leadership for the Board, including the Board's evaluation of management’s ERM process.
The Board of Directors meets in executive session without management present at each quarterly Board meeting and the Audit Committee meets in executive session at each quarterly Committee meeting, as well as having regular executive sessions with our Senior Director of Internal Audit and our independent registered public accounting firm.
Do Our Compensation Programs Create a Reasonable Likelihood of Material Adverse Effects for the Company?
Our general employee compensation programs are substantially less weighted toward incentive compensation and equity awards than those for our executive officers. While managers below the executive officers do have incentive compensation tied to Company performance, and may receive equity awards in the form of restricted stock, the relative weight of their fixed salary compensation is much greater than for the executive officers. While some sales personnel are heavily dependent on sales-based commissions, the terms on which they may make sales are controlled by business unit managers and corporate-level bookings and revenue recognition procedures overseen and administered by non-sales executives.
Although any compensation program can create incentives that may include an element of risk and prove to be inappropriate to future circumstances, or that may encourage behavior that proves to be risky for the organization, the Compensation Committee believes that our programs, for both executives and other employees, do not create a reasonable likelihood of material adverse effects for the Company. In reaching this conclusion, the Compensation Committee has considered the following:
Our compensation program consists of both fixed and variable components, as well as short and long-term performance measures. The fixed portion (i.e., base salary) provides a steady income to our employees regardless of the performance of our business or stock price. The variable portion (i.e., bonus and equity awards) is based upon our financial performance against short- and long-term objectives and multi-year time-based vesting criteria. This mix of compensation is designed to motivate our employees, including our executive officers, to produce superior short- and long-term corporate performance without taking unnecessary or excessive risks to the detriment of important business metrics.
For the variable portion of compensation, the executive bonus program is focused on profitability while the executive equity program awards have a mix of time-based and multi-year performance-based vesting. We believe that these programs provide a check on excessive risk taking because to inappropriately benefit one would be a detriment to the other. In addition, we prohibit all our executive officers from short selling Mercury stock or from buying or selling puts, calls, or other derivative securities related to Mercury stock. By prohibiting such hedging transactions our executives cannot insulate themselves from the effects of poor stock performance.
In order for any employee, including our executive officers, to be eligible for the corporate financial performance element of our bonus program, we must first achieve a certain level of profitability that is established by the Compensation Committee (we refer to this metric as “adjusted EBITDA”). We believe that focusing on profitability rather than other measures encourages a balanced approach to our performance and emphasizes consistent behavior across the organization.
Our executive bonus program payout is capped, as are our performance equity awards. We believe this mitigates excessive risk taking by limiting payouts even if we dramatically exceed our financial targets and other performance metrics.
Our bonus program has been structured around attaining a certain level of profitability for several years and we have seen no evidence that it encourages unnecessary or excessive risk taking.
We have a clawback policy and stock ownership requirements for our executive officers which we believe limit excessive risk taking.

21


The calculation of our adjusted EBITDA for the executive bonus program is reviewed and defined annually by our Compensation Committee and is designed to keep it from being susceptible to manipulation by any employee, including our named executive officers.
Does Mercury have a commitment to sustainability and provide information on its Environmental, Social, and Governance ("ESG") practices?
        We discuss on our website, www.mrcy.com, under "Who We Are" and "Corporate Sustainability" our commitment to sustainability and our ESG practices.
        Our Board of Directors and executives understand and embrace the importance to all of our primary stakeholders of environmental, social, and governance ("ESG") measurement and reporting. For a number of years, we have been addressing the aspects of ESG we believe have the greatest impact on our business, our stakeholders, and value creation. As it relates to environment and sustainability, our initial priorities include: talent management and culture; responsible sourcing and operational excellence; cyber security; and environmental stewardship. We have also addressed a number of key governance principles that are considered best practice and will continue to advance in this area as well. Of our areas of focus, we are more advanced in developing talent management and culture and cyber security because these have the greatest potential to create - and the highest risk to destroy - value for Mercury and our shareholders. We are committed to continued progress in our efforts, results, and reporting accountability, and will add both to what we do and how we report these efforts over time.
        For talent management and culture, we invest in the professional development of our team members, hiring and retaining a diverse workforce. We are committed to ongoing employee training in critical compliance areas including business ethics, export rules, and our culture of integrity. We adhere to high ethical and security standards and operating with integrity is a foundation of our culture and values. We disclose in the Corporate Sustainability section of our website gender, racial, and ethnicity data, our voluntary and involuntary termination rates, and our OSHA injury rates.
Identifying and quantifying historic pay gaps based solely on gender can be challenging given the unique backgrounds each of our employees brings to the company. Despite this challenge and evidencing our strong commitment to closing the historical gender pay gap in the U.S., in 2018 we engaged an internationally known human resources consulting firm to conduct an assessment to determine the extent to which gender could have an impact on pay levels across the organization for our U.S. employees. That assessment found that women - without adjustment for factors outside of gender that might reasonably command higher pay in the marketplace from employers - are paid on average approximately 2% - 4% less than men. Based on the assessment, we have proactively worked to address each employee's individual circumstances to determine whether the pay gap was associated with factors other than gender and initiated a process to provide pay adjustments for women, as appropriate. Any adjustments have been based on the statistically derived recommendations from our outside consultant, and we continuously leverage market data and other statistics to inform promotions, adjustments, and new hire offers to provide women with competitive pay without regard to gender.
        The layers of cyber security we have built into our business systems and incorporated into our processes help ensure the critical data that drives the development of customer solutions is secure and protects our employees' personal information. Our good work has been recognized and we remain committed to modeling industry best practices. We have deployed and have been relying upon a best in class industrial security program as evidenced by superior ratings from the U.S. Defense Counterintelligence and Security Agency (DCSA). Four of our cleared sites have been recognized with the James S. Cogswell Industrial Security Achievement Award in recent years, with our Andover, MA headquarters being recognized with this award in 2020; less than 1% of the 13,000+ cleared contractor locations receive this award annually.
        Responsible sourcing and operational excellence are an integral part of value creation. We work with all our suppliers to ensure that we all adhere to an equal and high standard of sustainability and ethical principles. We provide opportunities for small businesses to engage with us as we support our customers in the aerospace, defense, and intelligence markets. We work closely with many categories of small businesses, including small disadvantaged, women-owned, veteran-owned, service-disabled veteran-owned and historically underutilized business zone (HUBZone) companies.
        As a technology company, we have relatively limited exposure to environmental stewardship risks in our operations. We are committed to promoting environmental stewardship and introducing innovative processes and technologies that improve our efforts, including quantifying and disclosing our environmental impact along with our efforts to maximize future generations' ability to live, work, and play in our shared natural environment. We disclose in the Corporate Sustainability section of our website our energy and water usage at our U.S. facilities, including our scope 2 greenhouse gas (GHG) emissions for indirect emissions from the generation of purchased energy, as well as our GHG emissions from corporate travel.

        Our executive leadership team reviews our ESG efforts and the Compensation Committee of the Board of Directors reviews our ESG practices with a view toward how our efforts help attract, develop, and retain employee talent, including our culture and values as well as how we demonstrate our commitment to good corporate citizenship.
        Please see the Corporate Sustainability section of our website, www.mrcy.com, under "Who We Are" for detailed disclosures on our commitment to sustainability and ESG practices. Information contained on our website does not constitute part of this proxy statement or our annual report on Form 10-K.
Does Mercury have a commitment to culture and values?
We are aware that the workforce required to grow our business and deliver creative solutions is rich in diversity of thought, experience, and culture. Our diversity and inclusion focus on building and maintaining the talent that will create cohesive and collaborative teams that drive innovation.
Our industry leadership is attributable to the spirit and commitment of our employees.

DIRECTOR COMPENSATION
How are the directors compensated?
The Compensation Committee performs an annual review of non-employee director compensation. Our director compensation philosophy is to provide our non-employee directors with competitive compensation. Our compensation philosophy is intended to offer compensation that attracts highly qualified non-employee directors and retain the leadership and skills necessary to build long-term shareholder value.
Cash Compensation for Non-Employee Directors for Fiscal 2020
Directors who are also our employees receive no additional compensation for serving on the Board of Directors. During fiscal 2020, our non-employee directors received an annual cash retainer of $60,000 and the following positions received additional cash retainers:
Independent Chairman of the Board$45,000 per annum
Chairman of the Audit Committee25,000 per annum

Chairman of the Nominating and Governance Committee12,000 per annum
Chairman of the Government Relations Committee12,000 per annum
Chairman of the M&A and Finance Committee12,000 per annum
All of these retainers are paid in cash in quarterly installments. Directors are also reimbursed for their reasonable expenses incurred in connection with attendance at Board and committee meetings.
Equity Compensation for Non-Employee Directors for Fiscal 2020
New non-employee directors are granted restricted stock awards in connection with their first election to the Board. These awards are granted by the Board of Directors and consist of shares of restricted stock for the number of shares of common stock equal to $225,000 divided by the average closing price of our common stock during the 30 calendar days prior to the date of grant. These awards vest as to 50% of the covered shares on each of the first two anniversaries of the date of grant.
Non-employee directors also receive annual restricted stock awards for the number of shares of common stock equal to $150,000 divided by the average closing price of our common stock during the 30 calendar days prior to the date of grant. These awards vest on the first anniversary of the date of grant.
Non-employee directors will not be eligible to receive an annual restricted stock award for the fiscal year in which they are first elected. Non-employee directors who are first elected to the Board during the first half of our fiscal year will be eligible to receive an annual restricted stock award for the next fiscal year; otherwise, non-employee directors will not be eligible to receive their first annual restricted stock award until the second fiscal year following the fiscal year in which they are first elected to the Board.
Cash and Equity Compensation for Non-Employee Directors for Fiscal 2021
        The Compensation Committee, with the assistance of the Committee's independent compensation consultant, performed its annual review of the Company's compensation for non-employee directors. Based on market data, including data for our peer group, the Compensation Committee recommended, and the Board of Directors approved, the following changes to the compensation policy for non-employee directors effective for fiscal 2021:
eliminated the restriction that non-employee directors who are first elected to the Board during the second half of Company's fiscal year would not be eligible to receive an annual restricted stock award for the next fiscal year.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION ("SAY-ON-PAY")
Pursuant to Section 14A of the Securities Exchange Act of 1934, as amended, we provide our shareholders with the opportunity to vote to approve, on a nonbinding, advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with the compensation disclosure rules of the Securities and Exchange Commission.
As described in greater detail under the heading "Compensation Discussion and Analysis," we seek to closely align the interests of our named executive officers with the interests of our shareholders. Our compensation programs are designed to reward our named executive officers for the achievement of short-term and long-term strategic and operational goals, which should result in increased value for our shareholders, while at the same time avoiding the encouragement of unnecessary or excessive risk-taking.
Required Vote
This vote is advisory, which means that the vote on executive compensation is not binding on us, our Board of Directors, or the Compensation Committee. The vote on this resolution is not intended to address any specific element of compensation, but rather relates to the overall compensation of our named executive officers, as described in this proxy statement in accordance with the compensation disclosure rules of the Securities and Exchange Commission. To the extent there is a significant vote against our named executive officer compensation as disclosed in this proxy statement, the Compensation Committee will evaluate whether any actions are necessary to address our shareholders’ concerns.
The affirmative vote of a majority of the shares present or represented and entitled to vote either in person or by proxy is required to approve this Proposal 2.
Accordingly, we ask our shareholders to vote on the following resolution at the Annual Meeting:
"RESOLVED, that the Company's shareholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company's Proxy Statement for the Annual Meeting of Shareholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table, and the other related tables and disclosure."
Recommendation
The Board of Directors recommends a vote FOR the approval of the compensation of our named executive officers, as disclosed in this proxy statement.

PROPOSAL 3: APPROVAL OF AMENDED AND RESTATED 2018 STOCK INCENTIVE PLAN
In August 2020, our Board of Directors adopted, subject to the approval of our shareholders, our amended and restated 2018 Stock Incentive Plan (the "2018 Plan") to increase the number of shares available for issuance by 3,000,000 shares and make the additional changes discussed below.
Summary of Changes
Additional Shares
In order to be able to make anticipated grants, the Board has amended the 2018 Plan to increase the number of shares authorized for issuance under the 2018 Plan by an additional 3,000,000 shares. If the shareholders approve the proposed amendment and restatement of the 2018 Plan, the additional shares to be issued under the 2018 Plan will be authorized but unissued shares.
As of August 24, 2020, there were 1,693,970 shares available for issuance under the 2018 Plan, with 921,221 outstanding time-based and performance-based restricted and deferred shares (assuming maximum performance on all performance-based awards). There were no stock options outstanding under the 2018 Plan as of August 24, 2020. We believe the additional 3,000,000 shares requested for the plan, together with the shares available under the plan, should last for two or three fiscal years depending on our organic growth, future M&A transactions, and changes in the price of our common stock.
Other Changes
The amended 2018 Plan now includes minimum vesting provisions for stock options and stock appreciation rights similar to the other equity awards permitted under the plan. In the event stock options or stock appreciation rights awarded to employees have a performance-based goal, the vesting period will be at least one year, and in the event any stock options or stock appreciation rights awarded to employees have a time-based restriction, the vesting period will be at least three years, but vesting can occur incrementally over the three-year period. No portion of any stock option or stock appreciation right granted to employees may vest prior to the first anniversary of the grant date.
Corporate Governance and Best Practice Highlights
The 2018 Plan and our corporate guidelines reflect best practices in equity compensation, including:
awards do not vest solely on account of a change in control (requires a qualifying termination following a change in control or an acquiring company refusing to assume outstanding awards);
no repricing of stock options or stock appreciation rights;
no discounted stock options or stock appreciation rights;
awards are subject to forfeiture provisions;
the plan does not allow for "liberal share counting" (that is, reuse of shares tendered, exchanged, or withheld to cover option exercise costs, any award shares withheld to cover taxes, and all shares underlying an award of stock appreciation rights once such stock appreciation rights are exercised);
the plan does not contain any "evergreen" provisions that automatically add shares to the plan reserve;
no payment of dividends or dividend equivalents on unvested awards;
we require executives and directors to comply with significant stock ownership guidelines; and
we prohibit hedging and pledging of company stock.
Summary of the Amended and Restated 2018 Plan
The following is a summary of certain major features of the 2018 Plan. This summary is subject to the specific provisions contained in the full text of the 2018 Plan, which is attached as Appendix A to this proxy statement.
Plan Administration. The Compensation Committee has full power to select, from among the individuals eligible for awards, the individuals to whom awards will be granted, to make any combination of awards to participants, and to determine the specific terms and conditions of each award, subject to the provisions of the 2018 Plan. The Compensation Committee may
29


delegate to our CEO, our Chief Human Resources Officer, or any executive officer the authority to grant awards at fair market value to employees who are not subject to the reporting and other provisions of Section 16 of the Exchange Act.
Eligibility and Limitations on Grants. Persons eligible to participate in the 2018 Plan are those full or part-time officers, employees, non-employee directors, and other key persons (including consultants) of the Company and its subsidiaries as selected from time to time by the Compensation Committee. As of August 24, 2020, approximately 1,958 individuals were eligible to participate in the 2018 Plan. The closing price per share of our common stock as reported by the NASDAQ Global Select Market was $76.29 on August 24, 2020.
Shares Reserved for Issuance. Of the 2,862,000 shares of our common stock, par value $.01 per share, authorized for issuance under the 2018 Plan, there were only 1,693,970 shares remaining available for issuance as of August 24, 2020. If the proposed amendment to the plan is approved by shareholders, the aggregate number of shares reserved and available for issuance will be increased by 3,000,000 shares, and the total number of shares authorized for issuance under the 2018 Plan from its inception will be increased from 2,862,000 shares to 5,862,000 shares. With this change, the maximum number of shares of stock reserved and available for issuance under the 2018 Plan will be 5,862,000 shares, plus the number of shares of stock reserved and available for issuance under the Company's Amended and Restated 2005 Stock Incentive Plan (the "2005 Stock Incentive Plan") as of October 24, 2018, the date of shareholder approval of the original 2018 Plan. For purposes of this limitation, the shares of stock underlying any awards that are forfeited, are canceled, expire or are terminated (other than by exercise) under (i) the 2018 Plan or (ii) from and after shareholder approval of the 2018 Plan, the 2005 Stock Incentive Plan shall be added to the shares of stock available for issuance under the 2018 Plan. Shares tendered or held back upon exercise of an option or settlement of an award to cover the exercise price or tax withholding shall not be available for future issuance under the 2018 Plan. In addition, upon exercise of stock appreciation rights, the gross number of shares exercised shall be deducted from the total number of shares remaining available for issuance under the 2018 Plan. Also, shares purchased in the open market using proceeds received upon the exercise of a stock option shall not be available for future issuance under the 2018 Plan. The maximum award of stock options or stock appreciation rights granted to any one individual will not exceed 500,000 shares of common stock (subject to adjustment for stock splits and similar events) for any calendar year period.
Effect of Grants. The grant of any award other than a stock option or a stock appreciation right will reduce the number of shares of common stock available for issuance under the 2018 Plan by 2.0 shares of common stock for each such share actually subject to the award. The grant of a stock option or a stock appreciation right will be deemed as an award of one share of common stock for each such share actually subject to the award.
Stock Options. The 2018 Plan permits the granting of (1) options to purchase common stock intended to qualify as incentive stock options under Section 422 of the Code and (2) options that do not so qualify. Options granted under the 2018 Plan will be non-qualified options if they fail to qualify as incentive options or exceed the annual limit on incentive stock options. Non-qualified options may be granted to any persons eligible to receive incentive options and to non-employee directors and key persons. The option exercise price of each option will be determined by the Compensation Committee but may not be less than 100% of the fair market value of the common stock on the date of grant. The 2018 Plan provides for 5,862,000 shares that can be granted in the form of incentive stock options. No dividends or dividend equivalents shall be paid on stock options.
The term of each option will be fixed by the Compensation Committee and may not exceed seven years from the date of grant. The Compensation Committee will determine at what time or times each option may be exercised. Options may be made exercisable in installments and the exercisability of options may be accelerated by the Compensation Committee. Options may be exercised in whole or in part with written notice to the Company.
Upon exercise of options, the option exercise price must be paid in full (1) in cash, by certified or bank check, or other instrument acceptable to the Compensation Committee, (2) by delivery (or attestation to the ownership) of shares of common stock that are beneficially owned by the optionee, (3) subject to applicable law, by a broker pursuant to irrevocable instructions to the broker from the optionee, or (4) by net exercise.
To qualify as incentive options, options must meet additional federal tax requirements, including a $100,000 limit on the value of shares subject to incentive options that first become exercisable by a participant in any one calendar year.
In the event stock options awarded to employees have a performance-based goal, the vesting period will be at least one year, and in the event any stock options awarded to employees have a time-based restriction, the vesting period will be at least three years, but vesting can occur incrementally over the three-year period. No portion of any stock option granted to employees may vest prior to the first anniversary of the grant date.
Stock Appreciation Rights. The Compensation Committee may award a stock appreciation right either as a freestanding award or in tandem with a stock option. The Compensation Committee may award stock appreciation rights subject to such conditions and restrictions as the Compensation Committee may determine, provided that (1) upon exercise of a stock appreciation right granted in tandem with an option, the applicable portion of any related option shall be surrendered, and
30


(2) stock appreciation rights granted in tandem with options are exercisable at such time or times and to the extent that the related stock options are exercisable. The term of each stock appreciation right may not exceed seven years. No dividends or dividend equivalents shall be paid on stock appreciation rights.
In the event awards made to employees have a performance-based goal, the restriction period will be at least one year, and in the event any awards made to employees have a time-based restriction, the restriction period will be at least three years, but vesting can occur incrementally over the three-year period. No portion of any stock appreciation right granted to employees may vest prior to the first anniversary of the grant date.
Restricted Stock. The Compensation Committee may award shares of common stock to participants subject to such conditions and restrictions as the Compensation Committee may determine. These conditions and restrictions may include the achievement of certain performance goals and/or continued employment with the Company through a specified restricted period. However, in the event awards made to employees have a performance-based goal, the restriction period will be at least one year, and in the event any awards made to employees have a time-based restriction, the restriction period will be at least three years, but vesting can occur incrementally over the three-year period. No portion of any restricted stock award granted to employees may vest prior to the first anniversary of the grant date. Cash dividends and stock dividends, if any, with respect to restricted stock shall be withheld by the Company for the grantee's account, and shall be subject to forfeiture to the same degree as the shares of restricted stock to which such dividends relate. Except as otherwise determined by the Committee, no interest will accrue or be paid on the amount of any cash dividends withheld.
Deferred Stock Awards. The Compensation Committee may award phantom stock units as deferred stock awards to participants. Deferred stock awards are ultimately payable in the form of shares of common stock and may be subject to such conditions and restrictions as the Compensation Committee may determine. These conditions and restrictions may include the achievement of certain performance goals and/or continued employment with the Company through a specified vesting period. However, in the event awards made to employees have a performance-based goal, the restriction period will be at least one year, and in the event any awards have a time-based restriction, the restriction period will be at least three years, but vesting can occur incrementally over the three-year period. No portion of any deferred stock award granted to employees may vest prior to the first anniversary of the grant date. In the Compensation Committee's sole discretion and subject to the participant's compliance with the procedures established by the Compensation Committee and requirements of Section 409A of the Code, it may permit a participant to make an advance election to receive a portion of his or her future cash compensation otherwise due in the form of a deferred stock award. During the deferral period, a grantee shall have no rights as a shareholder; provided, however, that the grantee may be credited with dividend equivalent rights with respect to the phantom stock units underlying his deferred stock award, subject to such terms and conditions as the Committee may determine, but shall not be entitled to dividends, if any, or dividend equivalents prior to settlement.
Performance-Based Awards. The 2018 Plan provides that the Compensation Committee may require that the vesting of awards be conditioned on the satisfaction of one or more of the performance criteria.
Detrimental Activity. The Compensation Committee may cancel, rescind, suspend, or otherwise limit any award to a participant if the participant engages in detrimental activities, including rendering services to a competitor of the Company, disclosing confidential information without permission, refusing to assign inventions to the Company, soliciting employees or customers of the Company, engaging in an activity that results in a termination for cause, materially violating any internal policies of the Company, or being convicted of, or pleading guilty to, a crime.
Tax Withholding. Participants in the 2018 Plan are responsible for the payment of any federal, state, or local taxes that we are required by law to withhold upon any option exercise or vesting of other awards. Subject to approval by the Compensation Committee, depending on the withholding method, a grantee may elect to have such grantee’s tax withholding obligation satisfied at the minimum or other applicable withholding rate in the grantee’s applicable jurisdiction, including maximum applicable rates that may be utilized without creating adverse accounting treatment under Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor pronouncement thereto) and permitted under applicable withholding rules promulgated by the Internal Revenue Service or another applicable governmental entity, in whole or in part, by (i) authorizing the Company to withhold from shares of stock to be issued pursuant to any award a number of shares with an aggregate fair market value (as of the date the withholding is effected) that would satisfy such withholding amount, or (ii) transferring to the Company shares of stock owned by the grantee with an aggregate fair market value (as of the date the withholding is effected) that would satisfy such withholding amount.
Change of Control Provisions. The 2018 Plan provides that, if there is a change in control of the Company that is approved by the Board of Directors, if the grantee has a minimum of six months of service and within six months of the consummation of the change of control, the grantee’s employment is involuntarily terminated by us for reasons other than for "cause" or the grantee resigns for "good reason", 50% of such grantee’s unvested awards will become vested and immediately exercisable. If, in connection with the change of control, awards granted under the 2018 Plan are cancelled or otherwise terminated upon consummation of the change of control, then instead of accelerated vesting, the grantee will receive a cash
31


payment for 50% of the value of his or her unvested awards (determined based on the price of our common stock at the time of consummation of the change of control). The foregoing is conditioned on the grantee’s execution of an effective release of claims if the value of the accelerated vesting or cash payment exceeds $25,000.
If there is a change of control that is not approved by the Board of Directors, all of the unvested awards under the 2018 Plan (regardless of the grant date) will become vested and immediately exercisable upon the change of control. Further, upon any change of control all outstanding awards held by non-employee directors will automatically become fully vested.
Amendments and Termination. The Board may at any time amend or discontinue the 2018 Plan, and the Compensation Committee may at any time amend or cancel any outstanding award for the purpose of satisfying changes in the law or for any other lawful purpose. However, no such action may adversely affect any rights under any outstanding award without the holder’s consent. Any amendments that materially change the terms of the 2018 Plan, including any amendments that increase the number of shares reserved for issuance under the 2018 Plan, expand the types of awards available under the 2018 Plan, materially expand the eligibility to participate in the 2018 Plan, materially extend the term of the 2018 Plan, or materially change the method of determining the fair market value of common stock, will be subject to approval by shareholders. Amendments shall also be subject to approval by our shareholders if and to the extent determined by the Compensation Committee to be required by the Code to preserve the qualified status of incentive options. In addition, except in connection with a reorganization or other similar change in the capital stock of the Company or a merger or other transaction, without prior shareholder approval, the Compensation Committee may not reduce the exercise price of an outstanding stock option or stock appreciation right or effect repricing of an outstanding stock option or stock appreciation right through cancellation or regrants.
No Repricing of Awards Without Stockholder Approval. Notwithstanding any other provision of the 2018 Plan, the repricing of awards shall not be permitted without stockholder approval. For this purpose, a "repricing" means any of the following (or any other action that has the same effect as any of the following): (1) changing the terms of an award to lower its exercise or base price (other than on account of capital adjustments resulting from share splits, etc.); (2) any other action that is treated as a repricing under GAAP; and (3) repurchasing for cash or canceling an award in exchange for another award at a time when its exercise or base price is greater than the fair market value of the underlying share of stock, unless the cancellation and exchange occurs in connection with a capital adjustment event.
Grantees Outside of the United States. The Compensation Committee may modify the terms of any award under the 2018 Plan made to or held by a grantee who is then a resident, or is primarily employed or providing services, outside of the United States in any manner deemed by the Compensation Committee to be necessary or appropriate in order that such award shall conform to laws, regulations, and customs of the country in which the grantee is then a resident or primarily employed or providing services, or so that the value and other benefits of the award to the grantee, as affected by non–U.S. tax laws and other restrictions applicable as a result of the grantee's residence, employment, or providing services abroad, shall be comparable to the value of such award to a grantee who is a resident, or is primarily employed or providing services, in the United States. An award may be modified in a manner that is inconsistent with the express terms of the 2018 Plan, so long as such modifications will not contravene any applicable law or regulation or result in actual liability under Section 16(b) of the Exchange Act for the grantee whose award is modified. Additionally, the Compensation Committee may adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the 2018 Plan by eligible persons who are non–U.S. nationals or are primarily employed or providing services outside the United States.
Data Privacy. As a condition of receipt of any award, each grantee explicitly and unambiguously consents to the collection, use, and transfer, in electronic or other form, of personal data by and among, as applicable, the Company and its affiliates for the exclusive purpose of implementing, administering, and managing the 2018 Plan and awards. The Company and its affiliates may hold certain personal information about a grantee, including, but not limited to, the grantee’s name, home address, telephone number, date of birth, social security or insurance number or other identification number, salary, nationality, job title(s), information regarding any securities of the Company or any of its affiliates, and details of all Awards (the "Data"). In addition to transferring the Data amongst themselves as necessary for the purpose of implementation, administration, and management of the 2018 Plan and awards, the Company and its affiliates may each transfer the Data to any third parties assisting the Company in the implementation, administration, and management of the 2018 Plan and awards. Recipients of the Data may be located in the grantee's country or elsewhere, and the grantee's country and any given recipient's country may have different data privacy laws and protections. The Company may cancel the grantee’s eligibility to participate in the 2018 Plan, and in the Compensation Committee's discretion, the grantee may forfeit any outstanding awards if the grantee refuses or withdraws the consents described above.
U.S. Federal Income Tax Considerations
Awards of restricted stock under the 2018 Plan generally are not subject to federal income tax when awarded, unless the participant properly elects to accelerate the tax recognition. Restricted stock is generally subject to ordinary income tax at
32


the time the restrictions lapse. We are entitled to a corresponding deduction at the time the participant recognizes taxable income on the restricted stock.
Stock options under the 2018 Plan may either be granted as incentive stock options, which are intended to comply with the requirements of Internal Revenue Code Section 422 or as non-qualified stock options. Generally, no federal income tax is payable by the recipient upon the grant of an incentive stock option and no deduction is taken by us. If certain holding periods are met, the exercise of an incentive stock option does not result in taxation to the recipient; rather, the recipient is taxed only at the time of sale. If the shares have been held for at least one year after the date of exercise and at least two years from the date of grant of the option, the recipient will be taxed on any appreciation in excess of the exercise price as long-term capital gains. In that event, we are not entitled to a deduction for the amount of the capital gains. Under current tax laws, if a recipient exercises a non-qualified stock option, the recipient will be taxed on the difference between the fair market value of the stock on the exercise date and the exercise price and, thereafter, the recipient would receive capital gains on any appreciation in stock value after the exercise date, depending upon the length of time the recipient held the stock after exercise. When the option is exercised, we will be entitled to corresponding tax deduction.
New Plan Benefits
It is not possible to state the persons who will receive options or awards under the 2018 Plan in the future or the amount of options or awards that will be granted under the 2018 Plan. The following table provides information with respect to awards granted under the 2018 Plan in the fiscal year ended July 3, 2020. This table does not include any grants made following the end of fiscal year 2020 as described in "Compensation Discussion and Analysis."

PROPOSAL 4: APPROVAL OF AMENDED AND RESTATED 1997 EMPLOYEE STOCK PURCHASE PLAN
In August 2020, the Board of Directors adopted, subject to the approval of our shareholders, our amended and restated 1997 Employee Stock Purchase Plan (the "ESPP").
Summary of Changes
We offer eligible employees the opportunity to purchase shares of our common stock on a regular basis through payroll deductions under the ESPP. The purpose of the ESPP is to encourage ownership of our common stock by our employees. The ESPP is intended to be an "employee stock purchase plan" within the meaning of Section 423(b) of the Internal Revenue Code of 1986, as amended (the "Code").
The Board believes that the number of shares currently remaining available for issuance under the ESPP is not sufficient for future needs. We believe that continuing to offer eligible employees an opportunity to purchase shares of our common stock under the ESPP enables us to attract and retain key personnel, and helps to align employee and shareholder interests by encouraging employee stock ownership. Accordingly, our Board of Directors has adopted, and is seeking shareholder approval of, an amendment to the ESPP that would increase the aggregate number of shares of our common stock reserved and available for issuance under the ESPP by 500,000 shares. If the proposed amendment to the ESPP is not approved by shareholders, it is likely that all currently remaining shares available for issuance under the ESPP will be purchased in our current fiscal year.
Summary of the Amended and Restated ESPP
The following is a summary of certain major features of the amended and restated ESPP incorporating the changes to the plan discussed above. This summary is subject to the specific provisions contained in the full text of the amended and restated ESPP, which is attached as Appendix B to this proxy statement.
Term of the Plan. The ESPP will continue in effect until June 30, 2025. Our Board may terminate the ESPP at any time. The ESPP will terminate in any case when all or substantially all of the unissued shares of our common stock reserved for the purposes of the ESPP have been purchased.
Plan Administration. The Compensation Committee of our Board of Directors administers the ESPP and has full authority to make, administer, and interpret such equitable rules and regulations regarding the ESPP as it deems advisable.
Eligibility. Persons eligible to participate in the ESPP are full-time employees of Mercury or any of its subsidiaries designated as a participating employer who work at least 20 hours per week and more than five months per year, except for persons who are deemed for purposes of Section 423(b)(3) of the Code to own five percent or more of our voting stock. As of August 24, 2020 approximately 1,823 individuals were eligible to participate in the ESPP.
Purchase Periods; Exercise Price. The ESPP provides for two "purchase periods" within each calendar year, the first commencing on January 1 and ending on June 30, and the second commencing on July 1 and ending on December 31. Eligible employees may elect to become participants in the ESPP by enrolling prior to each semi-annual period. On the first day of each purchase period, subject to the terms of the ESPP, each eligible employee who is then a participant in the ESPP is granted an option to purchase on the last business day of the purchase period a number of shares of our common stock equal to (1) the aggregate payroll deductions in the purchase period authorized by the participant, divided by (2) the exercise price (as defined below). Shares are purchased through the accumulation of payroll deductions of not less than 1% nor more than 10% of each participant’s compensation, subject to an overall annual maximum of $25,000 per participant. The maximum number of shares that can be purchased by an individual participant in any purchase period is 833 shares (or such other number determined from time to time by the Compensation Committee).
The "exercise price" for each purchase period is equal to the lower of (1) 85% of the fair market value per share of our common stock on the first business day of the relevant purchase period, or (2) 85% of the fair market value per share of our common stock on the last business day of the relevant purchase period. As of August 24, 2020, the closing price per share of our common stock as reported by the Nasdaq Global Select Market was $76.29.
Participation/ Cancellation. A participant may only purchase shares under the ESPP during his or her lifetime and the ability to purchase shares under the ESPP is not transferable. A participant may cancel his or her participation in the ESPP with respect to any purchase period so long as the participant's notice of cancellation is received by us at least 10 days prior to the last business day of the purchase period. Participation in the ESPP automatically terminates upon a participant's termination of employment for any reason. Upon any such cancellation or termination, all accumulated payroll deductions are refunded in cash.

34


Shares Subject to the Plan. Of the 1,800,000 shares of our common stock, par value $.01 per share, authorized for issuance under the ESPP, there were only 28,779 shares remaining available for issuance as of August 24, 2020. If the proposed amendment to the ESPP is approved by shareholders, the aggregate number of shares reserved and available for issuance under the ESPP will be increased by 500,000 shares, and the total number of shares authorized for issuance under the ESPP from its inception will be increased from 1,800,000 shares to 2,300,000 shares. If our capital structure changes because of a stock dividend, stock split, or similar event, the number of shares that can be issued under the ESPP will be appropriately adjusted.
Amendments and Termination. Our Board of Directors may at any time amend or terminate the ESPP. However, any such termination by the Board will not affect a participant's ability to purchase shares then outstanding under the ESPP, and any such amendment will not adversely affect the ability to purchase shares then outstanding under the ESPP without the participant's consent. Certain amendments, such as an increase in the number of shares available for issuance under the ESPP, will not be effective without the approval of our shareholders.
U.S. Federal Income Tax Considerations
The ESPP is intended to qualify as an "employee stock purchase plan" as defined in Section 423(b) of the Code, which provides that an employee participating in the plan is not required to pay any federal income tax when joining the plan or when purchasing the shares of common stock at the end of the purchase period. The employee is, however, required to pay federal income tax on the difference, if any, between the price at which he or she sells the shares and the price he or she paid for them. If shares acquired under the ESPP are sold more than two years after the first day of the purchase period pursuant to which the shares were purchased, no taxable income results if the sale price is less than the price paid for the shares, and the employee will recognize a long-term capital loss for the difference between the sale price and the purchase price. If the proceeds of the sale are higher than the purchase price, the employee will recognize ordinary income for the year in which the sale occurs equal to the lesser of (a) fifteen percent (15%) of the fair market value of the common stock on the first day of the purchase period in which the shares were purchased, or (b) the excess of the amount actually received for the shares over the amount paid. In addition, the employee will recognize a long-term capital gain in an amount equal to the difference between the proceeds of the sale and the employee’s basis in the shares (i.e., the employee’s purchase price plus the amount taxed to the employee as ordinary income). No deduction is allowed to Mercury.
If shares acquired under the ESPP are sold within two years of the first day of the purchase period pursuant to which the shares were purchased, the employee will recognize ordinary income equal to the difference between the fair market value of the shares on the last business day of the purchase period in which the shares were purchased and the employee’s purchase price. This amount is reportable as ordinary income even if no profit was realized on the sale of shares or the shares were sold at a loss. Long-term or short-term (depending on the holding period for the shares) capital gain or loss will be recognized in an amount equal to the difference between the proceeds of sale and the employee's basis in the shares (i.e., the fair market value of the shares on the last business day of the purchase period in which the shares were purchased). The amount reportable as ordinary income for a sale made within two years of the first day of the purchase period pursuant to which the shares were purchased will generally be allowed as a tax deduction to Mercury.
New Plan Benefits
Since participation in the ESPP is voluntary, the benefits or amounts that will be received by or allocated to any individual or group of individuals under the amended and restated ESPP are not determinable.
Required Vote
Approval of the amended and restated ESPP requires the affirmative FOR vote of a majority of the votes cast on the proposal. Unless marked to the contrary, proxies received will be voted FOR approval of the amendment and restatement of the ESPP.
Recommendation
The Board of Directors recommends a vote FOR the amendment and restatement of the ESPP.

PROPOSAL 5: RATIFICATION OF APPOINTMENT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Audit Committee of the Board of Directors has appointed KPMG LLP as our independent registered public accounting firm for the fiscal year ending July 2, 2021. We are asking shareholders to ratify this appointment. Although ratification by shareholders is not required by law or by our by-laws, the Audit Committee believes that submission of its selection to shareholders is a matter of good corporate governance. Even if the selection is ratified, the Audit Committee, in its discretion, may select a different independent registered public accounting firm at any time if the Audit Committee believes that such a change would be in the best interests of Mercury and our shareholders. If our shareholders do not ratify the selection of KPMG, the Audit Committee will take that fact into consideration, together with such other factors it deems relevant, in determining its next selection of an independent registered public accounting firm.
Representatives of KPMG will attend the annual meeting, where they will have the opportunity to make a statement if they wish to do so and will be available to answer questions from shareholders.
Required Vote
Approval of the ratification of the appointment of KPMG as our independent registered public accounting firm for fiscal 2021 requires the affirmative FOR vote of a majority of the votes cast on the proposal. Unless marked to the contrary, proxies received will be voted FOR approval of the ratification of the appointment.
Recommendation
The Board of Directors recommends a vote FOR the ratification of the appointment of KPMG as our independent registered public accounting firm for fiscal 2021.

COMPENSATION DISCUSSION AND ANALYSIS
Fiscal 2020 Business Performance Highlights
At Mercury Systems, we deliver Innovation That Matters®. We make mission-critical technologies profoundly more accessible and affordable for aerospace and defense. Our fiscal 2020 results demonstrate that our customers trust us more than ever to meet their current and emerging technology and business needs. We delivered record bookings, revenue, net income, adjusted EBITDA, and adjusted EPS in fiscal 2020 against a challenging coronavirus backdrop. We continued to invest organically in the business for future growth, improved our performance in operations and manufacturing, acquired American Panel Corporation ("APC"), and concluded the year with zero debt and nearly $1 billion of financial capacity.
Our footprint has increased in recent years to more than 300 programs and platforms. Our top-line growth reflects this expansion. Revenue for fiscal 2020 increased 22% year-over-year to a new Company record of $797 million. Our largest revenue programs were SEWIP, F-35, P8, Filthy Buzzard and ARCI.
Organic revenue, excluding recent acquisitions, was up 14% from fiscal 2019. Bookings grew 22% to $954 million – our sixth straight record. Year-end backlog increased 33% to a record $831 million, positioning us to continue delivering above industry average growth in fiscal 2021. It was also a record year for new design wins, which amounted to more than $2 billion in total lifetime value.
Our business model continues to perform well, and Mercury delivered strong results on the bottom line in fiscal 2020. GAAP net income increased 83% from fiscal 2019, driven by improved operating performance and the positive impact of one-time, non-operating items. Adjusted EBITDA grew 21% to a record $176 million. It also was a record year for free cash flow, defined as operating cash flow less capital expenditures, at $72 million.
We are beginning fiscal 2021 in an excellent position strategically. The team is doing an outstanding job managing through the virus pandemic. Although the public health and economic risks remain elevated, we are positive about the business outlook.
We continue to believe that Mercury is targeting the right parts of the market. The wave of modernization occurring in radar, electronic warfare, and C4I continues to drive growth in the business. Demand in weapons systems, space, avionics processing, and mission computing, as well as secure rugged servers, remains healthy.
Our bookings and design win activity reflect the impacts of three industry trends that we have previously discussed: 1) supply chain delayering by the government and the defense primes; 2) the primes' flight to quality suppliers; and 3) increased outsourcing by the primes at the subsystem level. Potentially a fourth trend is the government's drive to create a domestic supply chain for secure and trusted advanced electronics capabilities designed and built in the U.S.
Protecting the health, safety and livelihoods of our employees has been the center of our decision making since the earliest days of the COVID pandemic. In return, our team has performed superbly in maintaining their productivity and overcoming our operational challenges.
We are optimistic about our ability to continue delivering organic revenue growth at a rate that exceeds the industry average, and confident that we can improve Mercury's financial performance by executing our plans in five areas:
deliver robust organic revenue growth, supplemented by growth from acquisitions;
invest in new technologies, in our manufacturing assets and business systems, and in our people;
enhance margins and drive working capital efficiencies through manufacturing insourcing and performance improvements;
create stronger operating leverage in the business by growing revenue faster than expenses; and
fully integrate our acquired businesses to generate cost and revenue synergies.
This strategy has worked very well over the past six years. Given our ability to execute, we are confident that Mercury will extend this record of success. We anticipate another year of strong growth in revenue and adjusted EBITDA in fiscal 2021, driven by high single-digit to low double-digit organic revenue growth, in line with our long-term strategy.

Executive Compensation Highlights and Alignment of Compensation with Business Strategy
Pay for Performance
Our executive compensation program is designed to motivate, engage, and retain a talented leadership team and to appropriately reward them for their contributions to our business. Our performance framework consists of a combination of financial performance measures that provide a balance between short-term results and drivers of long-term value. We provide our executive officers with three primary elements of pay: base salary; a performance cash bonus opportunity; and long-term equity incentive compensation. By placing a substantial majority of our executives' compensation at risk through performance-based variable compensation, we align our compensation program with our business strategy. The following charts show the pay mix for our CEO and our other named executive officers for fiscal 2020.
https://cdn.kscope.io/7f601bd32f59d091feb29d789a7507c4-chart12.jpg
        Performance-based variable compensation accounted for 88% and 79% of total compensation for our CEO and other named executive officers, respectively, for fiscal 2020. The foregoing percentages were calculated using the salary, annual cash bonuses, and the grant date fair value of equity awards as reported for fiscal 2020 in the Summary Compensation and Grants of Plan-Based Awards Tables below. All other compensation for our named executive officers for fiscal 2020, which consisted of a $12,000 allowance for tax and financial planning for executives, and a 401(k) match which is available to all employees, amounted to less than 1% of total compensation for named executive officers and is not reflected in the table above due to rounding.
Executive Bonus Program
For our fiscal 2020 executive bonus program, 100% of the total value was based on our achieving corporate financial performance objectives. Our fiscal 2020 executive bonus plan was split into two halves, with specific financial performance targets addressing the first half and the second half of the fiscal year. We used two semi-annual performance periods with two different performance targets in order to align our cash incentive program with our strategic operating plan ("SOP") review and midyear SOP update. We determined the potential total size of the annual cash incentive bonuses at the beginning of the fiscal year as well as set the first half financial performance target, and then set the second half and full year performance target in connection with our midyear SOP update. Potential over-achievement awards were based on exceeding the sum of the two half year corporate financial performance objectives. Our executive officers earned payouts at 100% of the first half target corporate financial performance bonus and 99% of the second half target corporate financial performance bonus. The target bonus was weighted 44% for the first half and 56% for the second half of the fiscal year, reflecting the fiscal 2020 adjusted EBITDA split between the first and second halves of the fiscal year in our SOP, with a catch-up feature for unearned first half cash incentives based on our full year performance. No over-achievement bonuses were earned for fiscal 2020. During the fourth quarter of fiscal 2020, we amended our adjusted EBITDA definition for external financial reporting to add back COVID-related costs as we believe these incremental expenses are outside the normal operations of the Company and are not indicative of ongoing operating results. The Compensation Committee maintained the original adjusted EBITDA target for the second half of the fiscal year and approved the use of the new adjusted EBITDA definition for the bonus plan for the second half of the fiscal year.
Executive Equity Awards
        Each fiscal 2020 restricted stock award for our named executive officers was 50% performance-based vesting and 50% time-based vesting. For the time-based vesting half of the fiscal 2020 awards, one-third vests on each of the first three anniversaries of the grant date. For the performance-based vesting half of the fiscal 2020 awards, the awards vest based on relative performance to our peer group for the three-year period ending in fiscal 2022. For fiscal 2020, we used two relative performance metrics for the
42


performance-based awards: (i) a ratio of adjusted EBITDA to revenue, percentile ranked relative to our peer group (50% weighting); and (ii) revenue growth percentage, percentile ranked relative to our peer group (50% weighting).
Our fiscal 2018 performance-based restricted stock awards vested at 250% based on our performance for the three-year period ended in fiscal 2020. Our fiscal 2018 performance awards used a mix of the ratio of adjusted EBITDA to revenue, percentile ranked relative to our peer group (75% weighting), and revenue growth percentage, percentile ranked relative to our peer group (25% weighting). Our financial results for the fiscal 2018 performance awards were at the 80th and 95th percentiles, respectively, of EBITDA margin and revenue growth compared to our peer group.

Compensation Philosophy and Objectives
We are a high-performing, results-driven organization made up of talented people:
who are engaged, developed, and challenged to achieve their full potential;
who are aligned to aggressive personal and business objectives; and
who are rewarded for their contribution to the achievement of Mercury's goals as a leading aerospace and defense electronics company, positioned at the intersection of high-tech and defense.
        Total compensation is designed to reward employees who share our values and achieve outstanding results in our high-performance organization. Paying for performance is the guiding principle of our total compensation strategy. Our pay for performance strategy is aligned with the interests of our shareholders, with the ultimate goal of driving, improving, and enhancing shareholder value.
        Our intent is to deliver actual total compensation that is aligned with our performance and that is competitive with technology and aerospace and defense peer companies that we compete with for talent. We pay salaries and all incentives aligned with the market for strong performance. Our headquarters is located in the greater Boston area, where competition for talent is particularly intense for executives with the experience and aptitude to motivate and lead engineers in designing, developing, and managing new subsystems, as well as qualified sales and operations personnel familiar with the unique requirements of the A&D industry.

Say-On-Pay Shareholder Vote Results
        We have held an annual non-binding advisory vote on the compensation of our named executive officers in our proxy statements since our 2011 annual meeting of shareholders. The following table shows the percentage of shareholder approval for the compensation of our named executive officers for the past five years:
Historical Say-On-Pay Vote Results
% Voted For97.54%97.38%99.39%83.24%99.46%
Year20152016201720182019
        As shown in this table, at our 2019 annual meeting of shareholders, the most recent non-binding shareholder vote on the compensation of our named executive officers, 99.46% of the votes cast by our shareholders were voted in favor of the compensation of our named executive officers.
        The Board of Directors has adopted a policy providing for an annual advisory vote on the compensation of our named executive officers. This policy is consistent with our shareholders’ preference as expressed at our 2017 annual meeting of shareholders on the frequency of holding future advisory votes on the compensation of our named executive officers.
How We Determine Executive Compensation
The Compensation Committee has responsibility for our executive compensation philosophy and the overall design of our executive compensation programs. The Compensation Committee is primarily responsible for setting executive compensation, which in the case of our CEO, is subject to ratification by a majority of the independent directors on the Board. Information about the Compensation Committee, including its composition, responsibilities, and processes, can be found earlier in this proxy statement under "Corporate Governance—What committees has the Board established? – Compensation Committee."
The compensation of our executive officers is reviewed and approved by the Compensation Committee (with ratification of the CEO's compensation by a majority of the independent directors on the Board). The Compensation Committee analyzes all elements of compensation separately and in the aggregate. In addition to evaluating our executives' contribution and performance in light of corporate financial performance objectives, we also base our compensation decisions on market considerations. The Compensation Committee benchmarks our cash and equity incentive compensation against programs available to employees in comparable roles at peer group companies and the Radford Global Technology Survey.
        The Compensation Committee has engaged the services of Mercer as an independent compensation consultant. Mercer assists the Compensation Committee in, among other things, applying our compensation philosophy for our executive officers and non-employee directors, analyzing current compensation conditions in the marketplace generally and among our peers specifically, and assessing the competitiveness and appropriateness of compensation levels for our executive officers. Representatives of Mercer periodically attend meetings of the Compensation Committee, both with and without members of management present, and interact with members of our human resources department with respect to its assessment of the compensation for our executive officers. In addition, Mercer may assist management in analyzing the compensation of our non-executive employees. For fiscal 2020, Mercer's services included providing compensation survey data for non-employee directors, executives, and non-executive employees. The Compensation Committee's expenditures for Mercer were $177,370 for fiscal 2020. For fiscal 2020, our human resources department expended $60,547 for Mercer market surveys for non-executive employees and selected job matches to market requests and other non-executive compensation related work.
In connection with its benchmarking efforts, the Compensation Committee uses data included in the Radford Global Technology Survey and also specific peer group data. The Compensation Committee annually reviews the companies included in our peer group and adds or removes companies as necessary to ensure that the peer group comparisons are meaningful.
Data with respect to the peer group listed below and the Radford Global Technology Survey was considered by the Compensation Committee in determining the base compensation, bonus targets, and the equity awards for fiscal 2020.

During fiscal 2020, Mercer assisted us in reviewing our peer group. We retained the same peer group with the following exception: we removed Cray Inc. from our peer group due to it being acquired in an M&A transaction.
        Data with respect to the updated peer group listed below and the Radford Global Technology Survey was considered by the Compensation Committee in determining the base compensation, bonus targets, and the equity awards for fiscal 2021.

CTS Corp.M/A-COM Technology Solutions Holdings, Inc. Ribbon Communications, Inc.
Diodes Inc.Methode Electronics, Inc.Rogers Corp.
In selecting our peer group, the Compensation Committee focused on company size (as indicated by revenue, number of employees, and market capitalization) and on creating a balanced and blended mix of companies in the defense and technology sectors. The Compensation Committee included technology companies in our peer group given our business model and financial profile is more aligned with technology companies than defense companies and because we most often compete with technology companies for executive and senior management talent. In addition, if the Compensation Committee had chosen purely defense companies for our peer group, our performance versus the peer group could conceivably be at the high end of the range.
In particular, the Compensation Committee reviewed the following elements of compensation against the benchmarking data:
base salary;
target bonus;
total target cash compensation (i.e., base salary plus target bonus);
target long-term incentive compensation, which consists of equity awards; and
target total direct compensation (i.e., target cash plus target long-term incentive compensation).
Each such element of compensation was compared to peer group data. The peer group used for fiscal 2020 had revenues generally between $474 million and $1.86 billion, with a median revenue of $781 million. By way of comparison, our revenue for fiscal 2020 was $797 million.
The Radford Global Technology Survey data and peer group data, as applicable, were reviewed together to form a final market data view. All forms of compensation were then evaluated relative to the market.
Our Elements of Total Compensation
Our total compensation program consists of fixed elements, such as base salary and benefits, and variable performance-based elements, such as annual and long-term incentives. Our fixed compensation elements are designed to provide a stable source of income and financial security to our executives. For fiscal 2020, our variable performance-based elements were designed to reward corporate financial performance compared to business goals for cash bonuses and growth and profitability relative to our peer group for performance-based equity awards.
The objective of this approach is to remain competitive with other companies in the same market for executive talent, while ensuring that our executives are given the appropriate incentives to deliver strong short- and long-term financial results. The Compensation Committee has chosen to put a substantial portion of each executive's total compensation at risk, contingent upon the achievement of our annual strategic operating plan profitability for performance-based cash bonuses, and growth and profitability relative to our peer group for performance-based equity awards.
Base salaries, target bonuses, and equity awards for our executive officers (other than the CEO) are set by the Compensation Committee following its review and approval of recommendations from the CEO. For the CEO, these elements of compensation are set by the Compensation Committee, and are subject to ratification by a majority of independent directors on the Board.

Base Salary
When the Compensation Committee annually considers executive base salaries, it takes into account each executive's role and level of responsibility. Individual compensation pay levels may vary relative to the market based on individual performance and other considerations, including the initial compensation levels required to attract qualified new hires and the compensation levels required to retain highly qualified executives.
For fiscal 2020, effective October 1, 2019, the Compensation Committee increased the base salaries for our named executive officers by 12% for our Chief Executive Officer, by 10% for our Chief Operating Officer, by 5% for our Chief Financial Officer, and by 3% for our General Counsel to the amounts below:
Named Executive Officer and Title           Fiscal 2020 Salary (effective October 1, 2019)
Mark Aslett, President and Chief Executive Officer
$692,000 
Christopher C. Cambria, EVP, General Counsel, and Secretary
377,000 
Michael D. Ruppert, EVP, Chief Financial Officer, and Treasurer
405,000 
Didier M.C. Thibaud, EVP, Chief Operating Officer
448,000 
These increases were consistent with market conditions and the growth in the size of the Company from acquisitions and organic growth.
A portion of Mr. Thibaud's salary is paid in Euros. The salary column in the Summary Compensation Table reflects the conversion of each monthly payment from Euros into U.S. Dollars (USD) based on the average conversion rate between Euros and USD for such month.
For fiscal 2021, effective September 26, 2020, the Compensation Committee increased the base salaries for our named executive officers by 6% for our Chief Executive Officer and by 3% for each of our General Counsel, Chief Financial Officer, and Chief Operating Officer to the amounts below:
Named Executive Officer and Title          Fiscal 2021 Salary (effective September 26, 2020)

Executive Bonus Program for Fiscal 2020
In establishing the executive bonus program for fiscal 2020, the Compensation Committee reviewed our multi-year performance and noted that our annual financial goals have been very aggressive relative to the financial performance of our peer group, with achievement of our strategic operating plan consistently positioning us in the top quartile. In order to provide incentives for continued top quartile performance going forward, the Committee set the target bonus as a percentage of base salary for the Chief Executive Officer at 150%; for each of the Executive Vice President, Chief Financial Officer and the Executive Vice President, Chief Operating Officer at 110%; and for the Executive Vice President, General Counsel at 90%.
Our executive bonus program is a variable performance-based element of our overall compensation program. This bonus program provides the potential for cash compensation for our executive officers based on achieving the corporate financial performance goals contained in the annual strategic operating plan that is approved by our Board of Directors in the first month of the fiscal year. Participants in the program are senior executives who have a strategic function and are recommended by the CEO to the Compensation Committee for participation in the program. In general, executives with the highest level and amount of responsibility have the highest percentage of their total target compensation at risk. This program consists of two elements: (1) target bonuses; and (2) potential over-achievement awards. Each executive officer's target bonus is determined based on position, responsibilities, and total target cash compensation, and may be subject to change from year to year. For fiscal 2020, each executive officer's target bonus was determined based on actual adjusted EBITDA (defined below) achieving budgeted adjusted EBITDA as set in our strategic operating plan for the fiscal year. Each executive officer's potential over-achievement award was determined based on actual adjusted EBITDA exceeding budgeted adjusted EBITDA for the fiscal year.
Adjusted EBITDA is a non-GAAP measure and all references to actual adjusted EBITDA in this Compensation Discussion and Analysis refer to such non-GAAP measure. As used in our fiscal 2020 executive bonus plan, adjusted EBITDA for the first half of the year included net income (prior to the impact, if any, of a payout of any potential over-achievement award) and was adjusted for the following: interest income and expense; other non-operating income (expense) not otherwise adjusted for; income taxes; depreciation; amortization of acquired intangible assets; restructuring and other charges; impairment of long-lived assets; acquisition and financing costs; fair value adjustments from purchase accounting; litigation and settlement expenses; and stock-based and other non-cash compensation expense. During the fourth quarter of fiscal 2020, we amended our adjusted EBITDA definition for external financial reporting to add back COVID-related costs as we believe these incremental expenses are outside the normal operations of the Company and are not indicative of ongoing operating results. The Compensation Committee maintained the original adjusted EBITDA target for the second half of the fiscal year and approved the use of the new adjusted EBITDA definition for the bonus plan for the second half of the fiscal year.  
A reconciliation between adjusted EBITDA and the most directly comparable GAAP financial measure is included as Appendix C to this proxy statement.
The following table indicates for fiscal 2020: (1) the target bonus for each named executive officer as a percentage of his base salary; and (2) the percentage of the target bonus tied to corporate financial performance objectives.

 Corporate Financial Performance Objectives
As part of our fiscal 2020 strategic operating plan, the Compensation Committee set the financial portion of our executive bonus plan for the first half of fiscal 2020 at the July 2019 meeting of the Board of Directors. The Compensation Committee set the financial portion of our executive bonus plan for the second half and full year for fiscal 2020 at the January 2020 meeting of the Board of Directors as part of our mid-year strategic operating plan review. At its April 2020 meeting, the Compensation Committee amended the definition of adjusted EBITDA in the bonus plan to add back COVID-related expenses but otherwise maintained the financial targets for the second half and full fiscal year that were approved at the January 2020 meeting. Payouts for corporate financial performance for fiscal 2020 were based on objectives for the fiscal year broken into the first half of the year and the full fiscal year, with a catch-up feature for unearned first half cash incentives based on our full year performance. The table below is a summary of the thresholds, targets, and maximums for the fiscal 2020 executive bonus plan, including the payout percentages for each element of the plan.

(1) The bonus targets for the second half and full year fiscal 2020 were set in January 2020. As a result, the first half and second half targets will not add up to the full fiscal year. We approved the second half and full fiscal year financial targets in January 2020 in connection with the Board of Director's review of our mid-year strategic operating plan, which reflects the completion of our acquisition of American Panel Corporation during the first half of the year.
Our executive officers earned payouts at 100% and 99%, respectively, for the first half and second half and full fiscal year corporate financial performance bonuses for fiscal 2020. No over-achievement bonuses were earned for fiscal 2020.
Performance-based bonuses comprised 19% of our CEO's compensation for fiscal 2020 and 22% of the compensation for our other executives, on average, for fiscal 2020.https://cdn.kscope.io/7f601bd32f59d091feb29d789a7507c4-chart31.jpg
Executive Bonus Program for Fiscal 2021
For fiscal 2021, the target bonus as a percentage of base salary for the Chief Executive Officer under the executive bonus program will be 150%; for each of the Chief Operating Officer and the Chief Financial Officer will be 110%; and for the General Counsel will be 90%. For fiscal 2021, the performance targets are based on our growth goals and margin expansion plans that are translated into a target level of adjusted EBITDA measured in dollars compared to budgeted adjusted EBITDA as set forth in our strategic operating plan for fiscal 2021, with targets again relating to the first and second halves of the fiscal year. Due to the
48


increased risks associated with the coronavirus pandemic, we have reduced the bonus payment threshold for fiscal 2021 to 60% of plan compared to our prior fiscal year threshold of 75% of plan.
Equity Compensation
We believe that compensation in the form of Mercury stock should be a significant portion of our executive officers’ total compensation in order to align with shareholder interests. Equity compensation creates a link to the creation of shareholder value. Our 2018 Stock Incentive Plan allows for several types of equity instruments, including stock options, stock appreciation rights, restricted stock, and deferred stock awards. The Compensation Committee determines which instruments to use on a grant-by-grant basis. When approving equity awards for an executive officer, the Compensation Committee considers the executive's current contribution to Mercury, the anticipated contribution to meeting our long-term strategic performance goals, and industry practices and norms. Long-term incentives granted in prior years, existing levels of stock ownership by executive officers, and aggregate grants to all executive officers are also taken into consideration. The Compensation Committee also considers the other elements of incentive compensation available to the executive officers and the performance metrics associated with those incentives, with a view toward providing an appropriately diverse set of different performance criteria and objectives to incent different aspects and time periods of performance and avoid multiple forms of reward for the same achievement.
In considering the executive’s current contribution to Mercury, the Compensation Committee reviews the executive's role within Mercury, the contribution that the executive is currently making to Mercury, the results achieved by the executive, and input from the CEO with respect to executive officers other than the CEO. In general, executives with higher levels and amounts of responsibility receive larger equity awards. As a result, the Chief Executive Officer, Chief Operating Officer, Chief Financial Officer, and General Counsel tend to have larger equity awards than our other executives.
In terms of the executive's anticipated contribution to meeting long-term strategic performance goals, the Compensation Committee reviews the potential role of the executive in achieving the long-term strategic goals set forth in our strategic operating plan, again with input from the CEO with respect to executives other than the CEO. The Compensation Committee considers the incentive and retention value that equity awards may provide.
Finally, the Compensation Committee reviews proposed equity awards to executives against benchmarking and peer group data. The Compensation Committee believes that equity awards create an incentive in addition to the executive bonus program in order to attract and retain senior executives who would contribute to our future success. As a result, the Compensation Committee intends for equity awards granted to executives as part of their long-term incentive compensation to generally be in line with industry practices and norms, both in terms of the type of equity award (e.g., restricted stock versus stock options) and the amount of the award.
The Compensation Committee has adopted an equity compensation awards policy that describes how equity awards are granted, including that any award granted to the CEO is subject to ratification by a majority of the independent directors on the Board.
Fiscal 2020 Equity Awards
The target number of shares awarded for the executive grant effective as of August 15, 2019 for each named executive officer was determined by dividing the dollar value fixed for such executive grant by the average closing price of our common stock during the 30 calendar days prior to August 15, 2019. The grant date of the fiscal 2020 equity awards was August 15, 2019.
Each fiscal 2020 restricted stock award for our named executive officers has 50% performance-based vesting and 50% time-based vesting. For the time-based vesting half of the fiscal 2020 awards, one-third vests on each of the first three anniversaries of the grant date. For the performance-based vesting half of the fiscal 2020 awards, the award vests based on relative performance to our peer group for the three-year period ending in fiscal 2022. For the fiscal 2020 performance-based awards, we used two relative performance metrics: (i) a ratio of adjusted EBITDA to revenue, percentile ranked relative to our peer group (50% weighting); and (ii) revenue growth percentage, percentile ranked relative to our peer group (50% weighting). These metrics were chosen to incent strong relative long-term growth in revenue and profitability. If we do not achieve at least the 25th percentile for a given performance metric, no vesting will occur for the performance-based shares tied to that metric. The maximum combined grant date value of the time and performance-based elements of the grant is capped at two times the award value.
Our fiscal 2020 executive compensation program utilized a diverse set of performance elements to drive different performance objectives over multiple time frames. Our fiscal 2020 executive cash bonus plan used adjusted EBITDA, expressed as a dollar amount, to drive profitability for fiscal 2020 in line with our strategic operating plan for the year. Our fiscal 2020 performance equity grant used a mix of the ratio of adjusted EBITDA to revenue, percentile ranked relative to our peer group (50% weighting), and revenue growth percentage, percentile ranked relative to our peer group (50% weighting), as performance measures to drive revenue growth and profitability over a three-year period. This is different from the absolute profitability measure used for our fiscal 2020 annual executive cash bonus plan, which cash plan was aligned with our fiscal 2020 strategic operating plan. Our
49


fiscal 2020 performance equity grant was aligned with relative performance compared with our peer group, an important factor in the creation of long term value for Mercury and its shareholders.

The maximum potential number of shares (assuming the highest level of performance achievement) that could be earned is: Mr. Aslett – 69,159 shares; Mr. Cambria – 13,830 shares; Mr. Ruppert – 22,725 shares; and Mr. Thibaud – 22,725 shares.
These equity grants were made based on the Compensation Committee’s assessment of both competitive annual grant levels and its determination of retention needs reflected by the pre-existing unvested long-term incentive awards previously granted to the executives.
Equity awards comprised 69% of our CEO's compensation for fiscal 2020 and 57% of the compensation for our other executives, on average, for fiscal 2020, in each case with half of the award using performance-based equity and the other half using time-based equity.

Fiscal 2018 Performance-Based Restricted Stock Awards
For the fiscal 2018 performance-based restricted stock awards, the performance period was calculated for the three-year period ended in fiscal 2020. Our fiscal 2018 performance equity grant used a mix of the ratio of adjusted EBITDA to revenue, percentile ranked relative to our peer group (75% weighting), and revenue growth percentage, percentile ranked relative to our peer group (25% weighting). Based on our relative performance compared with our peer group, the fiscal 2018 performance awards vested at 250%. Our financial results for the fiscal 2018 performance awards were at the 80th and 95th percentiles, respectively, of EBITDA margin and revenue growth compared to our peer group.
Fiscal 2019 Performance-Based Restricted Stock Awards
For the fiscal 2019 performance-based restricted stock awards, the performance period is the three-year period ending in fiscal 2021. Accordingly, none of these awards was eligible to vest for the period ended July 3, 2020.
Fiscal 2020 Performance-Based Restricted Stock Awards
For the fiscal 2020 performance-based restricted stock awards, the performance period is the three-year period ending in fiscal 2022. Accordingly, none of these awards was eligible to vest for the period ended July 3, 2020.

Fiscal 2021 Equity Awards
Since these awards occurred during fiscal 2021, they are not reflected in the Outstanding Equity Awards at Fiscal Year-End Table for fiscal 2020 included in this proxy statement. The target number of shares awarded for the executive grant effective as of August 17, 2020 for each named executive officer was determined by dividing the dollar value fixed for such executive grant by the average closing price of our common stock during the 30 calendar days prior to August 17, 2020. The grant date of the fiscal 2021 equity awards was August 17, 2020.
Each fiscal 2021 restricted stock award for our named executive officers is 50% performance-based vesting and 50% time-based vesting. For the time-based vesting half of the fiscal 2021 awards, one-third vests on each of the first three anniversaries of the grant date. For the performance-based vesting half of the fiscal 2021 awards, the award vests based on relative performance to our peer group for the three-year period ending in fiscal 2023. For the fiscal 2021 performance-based awards, we are using two relative performance metrics: (i) a ratio of adjusted EBITDA to revenue, percentile ranked relative to our peer group (50% weighting); and (ii) revenue growth percentage, percentile ranked relative to our peer group (50% weighting). These metrics were chosen to incent strong relative long-term growth in revenue and profitability.

Employee Benefits
We offer employee benefit programs that are intended to provide financial protection and security for our employees and to reward them for the total commitment we expect from them in service to Mercury. All of our named executive officers are eligible to participate in these programs on the same basis as our other employees. These benefits include the following: (1) medical, dental, and vision insurance, with employees sharing a percentage of the cost that may be adjusted from year to year; (2) Company-paid group life and accident insurance of one times base salary (up to $350,000); (3) employee-paid supplemental group life and accident insurance up to five times base salary (overall combined basic company-paid insurance plus supplemental insurance is $1,350,000); (4) short- and long-term disability insurance; (5) a qualified 401(k) retirement savings plan with a 50% company match up to 6% of eligible pay as contributed by the individual to the 401(k) plan (subject to IRS limits on contributions); and (6) an employee stock purchase plan, which entitles participants to purchase our common stock at a 15% discount.

Perquisites and Personal Benefits
For fiscal 2020, based on a market analysis performed by Mercer, the Compensation Committee's independent compensation consultant, we provided our executive officers with a $12,000 annual allowance for personal tax and financial planning. We plan to maintain the same executive perquisites for fiscal 2021.
Employment and Severance Agreements
We have entered into an employment agreement with Mr. Aslett and a severance agreement with each of our other executive officers as described below. The Compensation Committee consulted with Mercer regarding the market parameters of similar compensation arrangements for executive officers in connection with entering into these agreements. For more details, please refer to "Agreements with Named Executive Officers."
Change in Control Severance Agreements
We recognize that Mercury, as a publicly-traded company, may become the target of a proposal which could result in a change in control, and that such possibility and the uncertainty and questions which such a proposal may raise among management could cause our executive officers to leave or could distract them in the performance of their duties, to the detriment of Mercury and our shareholders. Our named executive officers have agreements intended to reinforce and encourage the continued attention of our executives to their assigned duties without distraction and to ensure the continued availability to Mercury of each of our executives in the event of a proposed change in control transaction. We believe that these objectives are in the best interests of Mercury and our shareholders. Provisions of these agreements relating to termination and change in control are summarized under "Potential Payments to Named Executive Officers upon Termination of Employment Following a Change in Control."
Tax Considerations
        Generally, Section 162(m) of the Internal Revenue Code disallows a federal income tax deduction for public corporations with respect to remuneration in excess of $1 million paid in any fiscal year to certain specified executive officers. For taxable years beginning before January 1, 2018, (i) these executive officers consisted of a public corporation's chief executive officer and up to three other executive officers (other than the chief financial officer) whose compensation is required to be disclosed to stockholders under the Securities Exchange Act of 1934, as amended, because they are our most highly-compensated executive officers, and (ii) qualifying "performance-based compensation" was not subject to this deduction limit if specified requirements were met.
        Pursuant to the Tax Cuts and Jobs Act of 2017, which was signed into law on December 22, 2017 (the Tax Act), for taxable years beginning after December 31, 2017, the remuneration of a public corporation's chief financial officer is also subject to the deduction limit. In addition, subject to certain transition rules (which apply to remuneration provided pursuant to written binding contracts that were in effect on November 2, 2017 and are not subsequently modified in any material respect), for taxable years beginning after December 31, 2017, the exemption from the deduction limit for "performance-based compensation" is no longer available. Consequently, for fiscal years beginning after December 31, 2017, no remuneration in excess of $1 million paid to a specified executive will be deductible (unless paid pursuant to an arrangement in effect on November 2, 2017).
        In designing our executive compensation program and determining the compensation of our executive officers, the Compensation Committee considers a variety of factors, including the potential impact of the Section 162(m) deduction limit. However, the Compensation Committee will not limit executive compensation to that which is or may be deductible under Section 162(m). The deductibility of some types of compensation depends upon the timing of an executive officer's vesting or exercise of previously granted rights. Further, interpretations of and changes in the tax law and other factors beyond the Compensation Committee's control also affect the deductibility of compensation.
        To maintain flexibility to compensate our executive officers in a manner designed to promote our short-term and long-term corporate goals, the Compensation Committee has not adopted a policy that all compensation must be deductible. The Compensation Committee believes that our stockholders' interests are best served if its discretion and flexibility in awarding compensation is not restricted, even though some compensation awards may result in nondeductible compensation expense.
Does Mercury have stock ownership guidelines and holding requirements for its Chief Executive Officer?
The CEO is expected to own or control, directly or indirectly, shares of Mercury common stock with a value of at least five times the CEO's base salary. The CEO is expected to meet this guideline within five years of first becoming CEO and is expected to retain such investment in the Company as long as he or she is the CEO. Prior to meeting the five times holding requirement per this guideline, after applicable tax withholding on the vesting of an equity award, the CEO is required to retain 50% of the net, after tax award until he or she is in compliance with the stock ownership guideline. Exceptions to this stock ownership guideline may be
52


approved from time to time by the Board as it deems necessary to address individual circumstances. Mr. Aslett's holdings of our common stock satisfy the stock ownership guidelines.
Does Mercury have stock ownership guidelines and holding requirements for its executives who report to the Chief Executive Officer?
Each of the executives who report directly to the CEO is expected to own or control, directly or indirectly, shares of the Mercury common stock with a value of at least three times the individual's base salary. Each such executive is expected to meet this guideline within five years of first becoming a direct report to the CEO, or within five years of January 22, 2019, whichever is later. Each such executive is expected to retain such investment in the Company as long as he or she is a direct report to the CEO. Prior to meeting the three times holding requirement per this guideline, after applicable tax withholding on the vesting of an equity award, the executive is required to retain 50% of the net, after tax award until he or she is in compliance with the stock ownership guideline. Exceptions to this stock ownership guideline may be approved from time to time by the Board as it deems necessary to address individual circumstances. Each of our executive's holdings of our common stock satisfy the stock ownership guidelines.
Does Mercury have a clawback policy?
        Yes. We have adopted a clawback policy applicable to our executive officers. This policy is posted on our website at www.mrcy.com on the "Investor Relations" page under "Corporate Governance." Pursuant to our policy, the Board of Directors shall, in all appropriate circumstances, require reimbursement of any annual incentive payment or long-term incentive payment to an executive officer where: (1) the payment was predicated upon achieving certain financial results that were subsequently the subject of a substantial restatement of Company financial statements filed with the SEC; (2) the Board determines the executive engaged in intentional misconduct that caused or substantially caused the need for the substantial restatement; and (3) a lower payment would have been made to the executive based upon the restated financial results.
Does Mercury have a short sale and hedging policy?
        Yes. Pursuant to our insider trading policy, no employee, executive officer, or director may at any time sell any securities of Mercury that are not owned by such person at the time of the sale. Also, no such employee, executive officer, or director may buy or sell puts, calls, or other derivative securities of Mercury at any time. In addition, no such employee, executive officer, or director may hold Mercury securities in a brokerage margin account.

(1)Represents the aggregate grant date fair value for equity awards made to our named executive officers in fiscal years 2018, 2019, and 2020. The amounts reported in this table do not reflect whether the named executive officer has actually realized a financial benefit from the award. Grant date fair value of equity awards is computed in accordance with Accounting Standards Codification Topic 718 (ASC Topic 718). For a discussion of the assumptions and methodologies used to calculate grant date fair value in this proxy statement, please refer to Note B of the financial statements in our annual report on Form 10-K for the fiscal year ended July 3, 2020. For the performance-based restricted stock awards, these amounts reflect the grant date fair value of such awards based upon the probable outcome at the time of grant.
