PROXY STATEMENT

FOR THE 20162019 ANNUAL MEETING OF STOCKHOLDERS



QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

Why did I receive a one-page notice in the mail regarding the Internet availability of proxy materials instead of a full set of proxy materials?

Pursuant to “Notice and Access” rules adopted by the Securities and Exchange Commission (the SEC), we have elected to provide access to our proxy materials over the Internet. Accordingly, we are sending an Important Notice Regarding the Availability of Proxy Materials (the Proxy Availability Notice) to our stockholders of record. All stockholders will have the ability to access the proxy materials on the website referred to in the Proxy Availability Notice free of charge or request to receive a printed set of the proxy materials for the Annual Meeting. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Proxy Availability Notice.

We provided some of our stockholders, including stockholders who have previously requestedasked to receive paper copies of the proxy materials, and some of our stockholders who are participants in our benefit plans, with paper copies of the proxy materials instead of the Proxy Availability Notice. If you received paper copies of the proxy materials, we encourage you to help us save money and reduce the environmental impact of delivering paper proxy materials to stockholders by signing up to receive all of your future proxy materials electronically.

We expect that this Proxy Statement and the other proxy materials will be available to stockholders on or about April 28, 2016.

26, 2019.

What does it mean if I receive more than one Proxy Availability Notice?

If you receive more than one Proxy Availability Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each Proxy Availability Notice to ensure that all of your shares are voted.

Will I receive any other proxy materials by mail?

We may send you a proxy card, along with a second Proxy Availability Notice, by mail on or after May 16, 2016.

How do I attend the Annual Meeting?

When are stockholder proposals for inclusion in our proxy statement for next year’s annual meeting due?

Stockholders wishing to present proposals for inclusion in our proxy statement for the 20172020 annual meeting of stockholders (the 20172020 Annual Meeting) pursuant to Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the Exchange Act), must submit their proposals so that they are received by us at our principal executive offices no later than December 30, 2016.27, 2019. Proposals should be sent to our Secretary at One Penumbra Place, Alameda, CA 94502.

When are other proposals and stockholder nominations for next year’s annual meeting due?

With respect to proposals and nominations not to be included in our proxy statement pursuant to Rule 14a-8 of the Exchange Act, our Amended and Restated Bylaws (our Bylaws) provide that stockholders who wish to nominate a director or propose other business to be brought before the stockholders at an annual meeting of

stockholders must notify our Secretary by a written notice, which notice must be received at our principal executive offices not less than 120 days nor more than 150 days prior to the anniversary date of the immediately preceding year’s annual meeting of stockholders.


4


Stockholders wishing to present nominations for director or proposals for consideration at the 20172019 Annual Meeting under these provisions of our Bylaws must submit their nominations or proposals so that they are received at our principal executive offices not earlier than January 9, 20177, 2020 and not later than February 8, 20176, 2020 in order to be considered. In the event that the 20172020 Annual Meeting is to be held on a date that is not within 30 days before or 70 days after the 1-year anniversary of the Annual Meeting, then a stockholder’s notice must be received by the Secretary no earlier than 120 days prior to such annual meeting and no later than the later of 70 days prior to the date of the meeting or the 10th day following the day on which we make a public announcement of the date of the 20172020 Annual Meeting.

A stockholder’s notice to nominate a director or bring any other business before the Annual Meeting or the 20172020 Annual Meeting must set forth certain information, which is specified in our Bylaws. A complete copy of our Bylaws may be found in the Governance section of the Investors section of our website at www.penumbrainc.com.

How are votes counted?

Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count, “For”, “Withhold” and broker non-votes for the proposal to elect directors, and with respect to other proposals, votes “For”, “Against”, “Abstain” and broker non-votes (if applicable).

What are “broker non-votes”?

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker, bank or other nominee holding the shares as to how to vote. Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker, bank or other nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker, bank or other nominee can still vote the shares with respect to matters that are considered to be “routine,” but cannot vote the shares with respect to “non-routine” matters. Under the rules and interpretations of the New York Stock Exchange (the NYSE), which generally apply to all brokers, bank or other nominees, on voting matters characterized by the NYSE as “routine,” NYSE member firms have the discretionary authority to vote shares for which their customers do not provide voting instructions. On non-routine proposals, such “uninstructed shares” may not be voted by member firms. Only the proposal to ratify the selection of our independent registered public accounting firm is considered a “routine” matter for this purpose and brokers, banks or other nominees generally have discretionary voting power with respect to such proposal. Broker non-votes will be counted for the purpose of determining whether a quorum is present at the Annual Meeting.

What is the effect of abstentions and broker non-votes?

Abstentions: Under Delaware law (under which Penumbra is incorporated), abstentions are counted as shares present and entitled to vote at the Annual Meeting, but they are not counted as shares cast. Our Bylaws provide that a stockholder action (other than the election of directors) shall be decided by the vote of the holders of a majority of the total number of votes of the Company’s capital stock cast on the matter. Therefore, abstentions will have no effect on Proposal No. 2—Ratification of the Selection by the Board of the Company’s Independent Registered Public Accounting Firm, orand Proposal No. 3—RatificationAdvisory Vote on Compensation of the 2014 Equity Incentive Plan.

Named Executive Officers.

Broker Non-Votes: A “broker non-vote” occurs when a broker, bank or other nominee holding your shares in street name does not vote on a particular matter because you did not provide the broker, bank or other nominee

voting instructions and the broker, bank or other nominee lacks discretionary voting authority to vote the shares because the matter is considered “non-routine” under the NYSE rules. The “non-routine” matters on the agenda for the Annual Meeting include Proposa1Proposal No. 1—Election of Directors, and Proposal No. 3—RatificationAdvisory Vote on Compensation of the 2014 Equity Incentive Plan.

Named Executive Officers.

Broker non-votes will be counted for the purpose of determining whether a quorum is present at the Annual Meeting. However, because broker non-votes are not considered under Delaware law to be entitled to vote at the Annual Meeting, they will have no effect on the outcome of the vote on Proposa1 No. 1—Election of Directors, or Proposal No. 3—RatificationAdvisory Vote on Compensation of the 2014 Equity Incentive Plan.Named Executive Officers. As a result, if you hold your shares in street name and you do not instruct your broker, bank or other nominee how to vote your shares in the election of directors or the advisory vote related to the approval of our executive compensation program,Say on Pay proposal, no votes will be cast on your behalf on these proposals.Therefore, it is critical that you indicate your vote on these proposals if you want your vote to be counted.The proposal to ratify the selection by the Board of Deloitte as our independent registered public accounting firm for the fiscal year ending December 31, 20162018 should be considered a “routine” matter. Therefore, your broker, bank or other nominee will be able to vote on Proposal No. 2—Ratification of the Selection by the Board of the Company’s Independent Registered Public Accounting Firm even if it does not receive instructions from you, so long as it holds your shares in its name.

A “Plurality,” with regard to the election of directors, means that the twothree nominees who receive the most “For” votes cast by the holders of shares either present in person or represented by proxy will be elected to our Board. A “Majority Cast,” with regard to the ratificationadvisory vote on compensation of the 2014 Equity Incentive Planour Named Executive Officers and the ratification of the selection by the Board of our independent registered public accounting firm means that a majority of the votes cast on the proposal are voted “For” the proposal.

Accordingly:

Proposal No. 1: For the election of directors, the twothree nominees receiving the most “For” votes from the holders of shares present in person or represented by proxy and entitled to vote on Proposal No. 1 will be elected as Class I directors to hold office until the 20192022 annual meeting of stockholders. Only votes “For” or “Withheld” will affect the outcome. Broker non-votes will have no effect.

Proposal No. 2: To be approved, a majority of the total votes cast on Proposal No. 2 must be voted “For” the ratification of the selection by the Board of Deloitte as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2016.2019. Abstentions and broker non-votes will not be considered votes cast on Proposal No. 2; however, the ratification of the selection by the Board of Deloitte is a matter on which a broker, bank or other nominee has discretionary voting authority, and thus, we do not expect any broker non-votes with respect to Proposal No. 2.

Proposal No. 3: To be approved, a majority of the total votes cast on Proposal No. 3 must be voted “For” the ratificationapproval on an advisory basis of the 2014 Equity Incentive Plan.compensation of our Named Executive Officers. Abstentions and broker non-votes will not be considered votes cast on Proposal NoNo. 3.

None of the proposals, if approved, entitles stockholders to appraisal rights under Delaware law or our charter.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid stockholder meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present in person or represented by proxy at the Annual Meeting. On the Record Date, there were 30,701,97134,732,088 shares outstanding and entitled to vote. Thus, the holders of at least 15,350,98617,366,045 shares must be present in person or represented by proxy at the Annual Meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy by mail, over the phone or through the Internet (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, then either the chair of the Annual Meeting or the holders of a majority of shares present at the Annual Meeting in person or represented by proxy may adjourn the meeting to another date. At any adjourned Annual Meeting at which a quorum is present, any business may be transacted that might have been transacted at the Annual Meeting as originally notified. If the adjournment is for more than 30 days, or if after that adjournment a new record date is fixed for the adjourned Annual Meeting, a notice of the adjourned Annual Meeting shall be given to each stockholder of record entitled to vote at the adjourned Annual Meeting.

How can I find out the results of the voting at the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a Current Report on Form 8-K that we expect to file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K with the SEC within four business days after the Annual Meeting, we intend to file a Form 8-K to publish the preliminary results within four business days after the Annual Meeting and file an additional Form 8-K to publish the final results within four business days after the final results are known to us.

JOBS Act Explanatory Note

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the JOBS Act).

For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,” including, but not limited to:

not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act;

not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;

reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and

exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

We could be an emerging growth company until the last day of the fiscal year following September 23, 2020, the fifth anniversary of the closing of our initial public offering, or until the earliest of (i) the last day of the first fiscal year in which our annual gross revenues exceed $1 billion, (ii) the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, which would occur at the end of the fiscal year during which the market value of our common stock held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, or (iii) the date on which we have issued more than $1 billion in non-convertible debt during the preceding three year period. Under Section 107(b) of the JOBS Act, emerging growth companies may delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, are subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

Because we have elected to take advantage of certain reduced disclosure obligations and may elect to take advantage of other reduced reporting requirements in future filings, the information that we provide to our stockholders may be different than you might receive from other public reporting companies in which you hold equity interests.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

This section describes key corporate governance guidelines and practices that we have adopted. Complete copies of our Corporate Governance Guidelines, the charters of the committees of the Board and our Code of Business Conduct and Ethics, described below, can be found in the Governance—Corporate Governance section of the Investors section of our website at www.penumbrainc.com. Alternatively, you can request a copy of any of these documents free of charge by writing to: Robert D. Evans,Johanna Roberts, Executive Vice President, General Counsel and Secretary, c/o Penumbra, Inc., One Penumbra Place, Alameda, CA 94502. Information on our website is not incorporated by reference in this Proxy Statement.

BOARD COMPOSITION

Our Board currently consists of sixseven members. In accordance with our Restated Certificate of Incorporation and our Bylaws, our Board is divided into three classes with staggered terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. The authorized number of directors may be changed by resolution of the Board. Our directors are divided among the three classes as follows:

Class I directors consist of Don Kassing, Janet Leeds, and Kevin Sullivan,Thomas Wilder, whose terms expire at the Annual Meeting;Meeting;

Class II directors consist of Arani Bose, M.D., and Walter Wang,Bridget O’Rourke, whose terms expire at the 2017 Annual Meeting;2020 annual meeting of stockholders; and

Class III directors consist of Adam Elsesser and Harpreet Grewal, whose terms expire at the 20182021 annual meeting of stockholders.

Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective terms. Each director’s term continues until the election and qualification of his successor, or his earlier death, resignation or removal.

INDEPENDENCE OF THE BOARD OF DIRECTORS

The Board has affirmatively determined that all of the nominees and continuing directors, other than Mr. Elsesser and Dr. Bose, are independent directors within the meaning of the applicable NYSE listing standards and relevant securities and other laws, rules and regulations regarding the definition of “independent” (the Independent Directors). There are no family relationships between any director and any of our executive officers.

BOARD LEADERSHIP STRUCTURE

The Board believes that it is important to retain the flexibility to allocate the responsibilities of the offices of Chairman of the Board (Chair) and Chief Executive Officer in any manner that it determines to be in the best interests of the Company at any point in time.


12


The Board reviews its leadership structure periodically as part of its annual self-assessment process. In addition, the Board continues to monitor developments in corporate governance as well as the approaches our peers undertake. Since January 2015, the Board has determined to combine the roles of Chair and Chief Executive Officer under the leadership of our co-founder Adam Elsesser. At the present time, the Board believes that this is the most effective leadership structure for Penumbra. We believe that combining the Chief Executive Officer and Chair positions helps ensure that the Board and management act with a common purpose. The Board believes that Mr. Elsesser’s combined role enables strong leadership, creates clear accountability and enhances our ability to communicate our message and strategy clearly and consistently to stockholders. In addition, we

believe that a combined Chief Executive Officer and Chair is better positioned to act as a bridge between management and the Board, maintaining the regular flow of information. The Board believes that the current board leadership structure, coupled with a strong emphasis on board independence, provides effective independent oversight of management while allowing the Board and management to benefit from Mr. Elsesser’s demonstrated senior leadership skills, expertise from years of experience in the medical device industry, and his experience and familiarity with our business as co-founder and Chief Executive Officer. Our Independent Directors bring experience, oversight and expertise from outside of our Company, while Mr. Elsesser brings company-specific experience and expertise.

The Board does not have a lead independent director. Our Corporate Governance Guidelines note that all directors are elected by the stockholders and all have an equal voice. The Board, therefore, does not believe it appropriate or necessary in serving the best interests of the Company to designate a lead director. The Chair and the Chief Executive Officer are free, as is the Board as a whole, to call upon any one or more directors to provide leadership in a given situation should a special need arise.

The Board has designated Don Kassing as the Presiding Director to lead the meetings of the non-managementnon-employee directors. If the designated Presiding Director is not present for a meeting, the other non-managementnon-employee directors appoint one of their number to act as Presiding Director for the meeting.

The Board, including each of its committees, also has complete and open access to any member of the Company’s management and the authority to retain independent advisors as the Board or such committee deems appropriate. In addition, all members of the Audit Committee, the NCG Committee and the Compensation Committee are Independent Directors, and the committee chairs have authority to hold executive sessions without management and non-Independent Directors present.

ROLE OF THE BOARD IN RISK OVERSIGHT

One of the Board’s key functions is informed oversight of the Company’s risk management process. The Board believes that its current leadership structure facilitates its risk oversight responsibilities. In particular, the Board believes the majority-independent Board and independent Board committees provide a well-functioning and effective balance to an experienced Chair. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through the various Board standing committees that address risks inherent in their respective areas of oversight. For example, the Board acts as the ultimate decision-making body of the Company and advises and oversees management, who are responsible for the day-to-day operations and management of the Company. The Audit Committee monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our internal audit function.function, and reviews the Company’s policies and practices with respect to risk assessment and risk management. The NCG Committee monitors the effectiveness of our corporate governance guidelines and policies. The Compensation Committee assesses and monitors whether any of our compensation programs, policies and programspractices has the potential to encourage excessive risk-taking.

It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board as quickly as possible. The Company’s Executive Vice President and General Counsel and Chief Financial Officer and Head of Strategy coordinate between the Board and management with regard to the determination and implementation of responses to any problematic risk management issues.

MEETINGS OF THE BOARD OF DIRECTORS

The Board oversees our business. It establishes overall policies and standards and reviews the performance of management. During the fiscal year ended December 31, 2015,2018, the Board held 13 meetings and took action by unanimous written consent on two occasions.six meetings. Each Board member

attended 75% or more of the aggregate meetings of the Board and of the committees on which he or she served held during the period for which he or she was a

director or committee member. The Company’s directors are encouraged to attend our annual meetings of stockholders, but we do not currently have a policy relating to director attendance. We did not hold a 2015 annual meetingOne of stockholders because we were not a publicly-traded company prior to September 2015.

the six directors serving at the time of the 2018 Annual Meeting of Stockholders attended that meeting.

Applicable NYSE listing standards require that non-managementnon-employee directors meet at regularly scheduled executive sessions without management. The Independent Directors meet from time to time in executive session. In accordance with the NYSE Standards, the Board typically holds an executive session of non-managementnon-employee directors (all of whom are Independent Directors), presided over by the Presiding Director, as a part of every regularly scheduled quarterly meeting of the Board.

INFORMATION REGARDING COMMITTEES OF THE BOARD OF DIRECTORS

The Board has a number of committees that perform certain functions for the Board. The current committees of the Board are the Audit Committee, the Compensation Committee, the NCG Committee, and the NCGExecutive Committee. Below is a description of each committee of the Board. Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The Board has determined that each member of each committeethe Audit Committee, the Compensation Committee, and the NCG Committee meets the applicable NYSE listing standards and relevant securities and other laws, rules and regulations regarding “independence” and that each member of the Audit Committee, the Compensation Committee, and the NCG Committee is free of any relationship that would impair his or her individual exercise of independent judgment with regard to our Company.

Audit Committee

The Board has a separately designated standing Audit Committee established in accordance with Section 3(a)(58) of the Exchange Act. The Audit Committee was established by the Board to assist the Board in its oversight of the integrity of our financial statements and internal controls, the design, implementation and performance of our internal audit function, and our compliance with legal and regulatory requirements. In addition, the Audit Committee assists the Board in its oversight of the qualification, independence and performance of our independent registered public accounting firm and recommends to the Board the appointment of our independent registered public accounting firm.

The Audit Committee was established in August 2015 and is currently composedconsists of threefour directors: Messrs. Kassing, Wang and Grewal (Chair). In 2015, the, Kassing, and Wilder, and Ms. O’Rourke. The Audit Committee met two times. six times during 2018.
The Audit Committee is governed by a written charter, which was adopted by the Board in August 2015. The Audit Committee charter can be found in the Governance—Corporate Governance section of the Investors section of our website at www.penumbrainc.com. Information on our website is not incorporated by reference in this Proxy Statement. The Audit Committee charter grants the Audit Committee authority to obtain, at our expense, advice and assistance from internal and external legal, accounting or other advisors and consultants and other external resources that the Audit Committee considers necessary or appropriate in the performance of its duties.

As required by its charter, the Audit Committee conducts a self-evaluation at least annually. The Audit Committee also reviews and assesses the adequacy of its charter at least annually and recommends any proposed changes to the Board for its consideration.

The Board annually reviews the NYSE listing standards’ definition of independence for Audit Committee members and has determined that all members of our Audit Committee are “independent” and “financially literate” under the NYSE listing standards and that members of the Audit Committee received no compensation from the Company other than for service as a director. The Board has determined that each of Mr.Messrs. Grewal, Kassing, and Mr. KassingWilder, and Ms. O’Rourke, qualifies as an “audit committee financial expert,” as defined in applicable SEC rules. In making that determination, the Board relied on the past business experience of Messrs. Grewal, Kassing, and Kassing.Wilder, and Ms. O’Rourke. Please see the description of the business experience for Messrs. Grewal, Kassing, and KassingWilder, and Ms. O’Rourke under the heading “Nominees for Director and Continuing Directors.”

Report of the Audit Committee of the Board of Directors

The Audit Committee reviews the Company’s financial reporting process on behalf of the Board. Management has the primary responsibility for the preparation and integrity of the consolidated financial statements and the reporting process, including establishing and monitoring the system of internal financial controls. In this context, during fiscal year 2015,2018, the Audit Committee met and held discussions with management and Deloitte & Touche LLP (Deloitte), the Company’s independent registered public accounting firm. Management has represented to the Audit Committee that the Company’s consolidated financial statements for the fiscal year ended December 31, 2015,2018, were prepared in accordance with accounting principles generally accepted in the United States of America, and the Audit Committee has reviewed and discussed the audited financial statements of the Company with management of the Company and with Deloitte. In addition, the Audit Committee has discussed with Deloitte the matters required to be discussed by Auditing Standard No. 16,1301, Communications with Audit Committees, as adopted by the Public Company Accounting Oversight Board (PCAOB). The Audit Committee has received from Deloitte the written disclosures and the letter required by applicable requirements of the PCAOB regarding Deloitte’s communications with the Audit Committee concerning independence and has discussed with Deloitte the independence of Deloitte from the Company and its management. The Audit Committee has also concluded that the provision of the non-audit services to the Company in fiscal year 20152018 was compatible with Deloitte’s independence. Based on the foregoing, the Audit Committee has recommended to the Board, and the Board has approved, that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015,2018, for filing with the SEC. The Audit Committee and the Board have also recommendedapproved the selection of Deloitte as the Company’s independent registered public accounting firm for the year ending December 31, 2016.

Nominating and Corporate Governance Committee

The NCG Committee is generally responsible for identifying qualified Board candidates, recommending director nominees and appointments to Board committees, evaluating Board performance, overseeing director compensation and overseeing the Company’s Corporate Governance Guidelines. To that end, the NCG Committee is responsible for, without limitation:

identifying and recommending candidates for membership on the Board;

reviewing and recommending to the Board the compensation of our directors;
reviewing and recommending our corporate governance guidelines and policies;

reviewing proposed waivers of the code of conduct for directors and executive officers;

overseeing the process of evaluating the performance of the Board; and

assisting the Board on corporate governance matters.

A detailed discussion of the NCG Committee’s procedures for recommending candidates for election as a director appears below under the captionProcedures of the Nominating and Corporate Governance Committee.

The NCG Committee was established in August 2015 and is composedcurrently consists of three directors, each of whom is “independent” under the listing standards of the NYSE. The members of the NCG Committee arefour directors: Messrs. Kassing (Chair), Grewal, and Sullivan.Wilder, and Ms. O’Rourke. The NCG Committee did notmet three times during 2018. The Board has determined that all members of our NCG Committee meet during 2015.

the independence requirements under SEC rules and NYSE listing standards.

The NCG Committee is governed by a written charter, which was adopted by the Board in August 2015. The NCG Committee charter can be found in the Governance—Corporate Governance section of the Investors section of our website at www.penumbrainc.com. The NCG Committee charter complies with the guidelines established by the NYSE. Information on our website is not incorporated by reference in this Proxy Statement. The charter of the NCG Committee grants the NCG Committee authority to retain and terminate any advisers, including search firms to identify director candidates, compensation consultants as to director compensation and legal counsel, including sole authority to approve all such advisers’ fees and other retention terms.

As required by its charter, the NCG Committee conducts a self-evaluation at least annually. The NCG Committee also periodically reviews and assesses the adequacy of its charter and recommends any proposed changes to the Board for approval.

Procedures of the Nominating and Corporate Governance Committee

In connection with nominating directors for election at the Annual Meeting and periodically throughout the year, the NCG Committee considers the composition of the Board and each committee of the Board to evaluate its effectiveness and whether or not changes should be considered to either the Board or any of the committees. In support of this process, the Board has determined that the Board as a whole must have the right diversity, mix of characteristics and skills for the optimal functioning of the Board in its oversight of our Company. The Board considers the following factors and qualifications:

the appropriate size and the diversity of the Board;

the needs of the Board with respect to the particular talents and experience of its directors;

the knowledge, skills and experience of nominees, including experience in the industry in which the Company operates, business, finance, management or public service, in light of prevailing business conditions and the knowledge, skills and experience already possessed by other members of the Board;

familiarity with domestic and international business matters;


18


legal and regulatory requirements; and

experience with accounting rules and practices.

Pursuant to the NCG Committee charter, the NCG Committee intends to periodically review the composition of the Board in light of the current challenges and needs of the Board and the Company, and determine whether it may be appropriate to add or remove individuals after considering issues of judgment, diversity, skills, background and experience. Although the NCG Committee does not have a formal policy respecting diversity on the Board, the NCG Committee is sensitive to the importance of nominating persons with different perspectives and experience to enhance the deliberation and decision-making processes of the Board.

Once the NCG Committee and the Board determine that it is appropriate to add a new director, either as a replacement or as a new position, the NCG Committee uses a flexible set of procedures in selecting individual director candidates. This flexibility allows the NCG Committee to adjust the process to best satisfy the objectives it is attempting to accomplish in any director search. The first step in the general process is to identify the type of candidate the NCG Committee may desire for a particular opening, including establishing the specific target skill areas, experiences and backgrounds that are to be the focus of a director search. The NCG Committee may consider candidates recommended by management, by other members of the NCG Committee, by the Board, by stockholders, or it may engage a third party to conduct a search for possible candidates. In considering candidates submitted by stockholders, the NCG Committee will take into consideration the needs of the Board and the qualifications of the candidate.

In order for a stockholder to have a candidate considered by the NCG Committee, a stockholder should submit a written recommendation that includes (A) as to each person whom the stockholder proposes to nominate for election or reelection as director,director: (1) all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act, including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected; and (2) a reasonably detailed description of any compensatory, payment or other financial agreement, arrangement or understanding that such person has with any other person or entity other than the Company including the amount of any payment or payments received or receivable thereunder, in each case in connection with candidacy or service as a director of the Company, and (B) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the proposal is made: (1) the name and address of such stockholder (as they appear on the Company’s books) and any such beneficial owner; (2) for each class or series, if any, the number of shares of capital stock of the Company that are held of record or are beneficially owned by such stockholder and by any such beneficial owner; (3) a description of any agreement, arrangement or understanding between or among such stockholder and any such beneficial owner, any of their respective affiliates or associates, and any other person or persons (including their names) in connection with the proposal of such nomination or other business; (4) a description of any agreement, arrangement or understanding (including, regardless of the form of settlement, any derivative, long or short positions, profit interests, forwards, futures, swaps, options, warrants, convertible securities, stock appreciation or similar rights, hedging transactions and borrowed or loaned shares) that has been entered into by or on behalf of, or any other agreement, arrangement or understanding that has been made, the effect or intent of which is to create or mitigate loss to, manage risk or benefit of share price changes for, or increase or decrease the voting power of, such stockholder or any such beneficial owner or any such nominee with respect to the Company’s securities; (5) a representation that the stockholder is a holder of record of stock of the Company entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to bring such nomination or other business before the meeting; (6) a representation as to whether such stockholder or any such beneficial owner

intends or is part of a group that intends to (i) deliver a proxy statement and/or form of proxy to holders of at least the percentage of the voting power of the Company’s outstanding capital stock required to approve or adopt the proposal or to elect each such nominee and/or (ii) otherwise to solicit proxies from stockholders in support of such proposal or nomination; (7) any other information relating to such stockholder, beneficial owner, if any, or director nominee or proposed business that would be required to be disclosed in a proxy statement or other filing required to be made in connection with the solicitation of proxies in support of such nominee or proposal pursuant to Section 14 of the Exchange Act; and (8) such other information relating to any proposed item of business as the Company may reasonably require to determine whether such proposed item of business is a proper matter for stockholder action. Stockholder recommendations should be addressed to the NCG


19


Committee in care of our Secretary at the address set forth below under the headingStockholder Communications with the Board of Directors.

Once candidates are identified, the NCG Committee conducts an evaluation of qualified candidates. The evaluation generally includes interviews and background and reference checks. There is no difference in the evaluation process of a candidate recommended by a stockholder as compared to the evaluation process of a candidate identified by any of the other means described above. In identifying and evaluating potential nominees to serve as directors, the NCG Committee will examine each nominee on a case-by-case basis regardless of who recommended the nominee and take into account all factors it considers appropriate.

If the NCG Committee determines that a candidate should be nominated as a candidate for election to the Board, the candidate’s nomination is then recommended to the Board, and the directors may in turn conduct their own review to the extent they deem appropriate. When the Board has agreed upon a candidate, such candidate is recommended to the stockholders for election at an annual meeting of stockholders or appointed as a director by a vote of the Board as appropriate.

Our stockholder and investor outreach includes investor road shows, analyst meetings, and investor conferences and meetings. We also communicate with stockholders and other stakeholders through various media, including our annual report and SEC filings, proxy statement, news releases, and our website. Our conference calls for quarterly earnings releases are open to all. These calls are available in real time and as archived webcasts on our website for a period of time.

DIRECTOR STOCK OWNERSHIP GUIDELINES

The Corporate Governance Guidelines include stock ownership guidelines for our non-employee directors, which have been adopted by the Company. Under these guidelines, directors are expected to hold meaningful equity ownership positions in Penumbra. Specifically, each member of the Board must own at least 5,000 shares of the Company’s stock. Newly elected directors will have three years to comply with their specific stock ownership guidelines.

Board. The Board believes these stock ownership guidelines are an important tool in aligning the interests of our directors with the long-term interests of our stockholders. As

Under the stock ownership and retention guidelines for non-employee directors approved by the Board in April 2017, our non-employee directors are expected to hold shares of the Company’s common stock with a value equal to three times (3x) the director’s annual cash retainer (the Ownership Requirement). The value of a share of the Company’s common stock is calculated as of December 31, 2015, all31st of each calendar year (the Determination Date) based on the adjusted closing price of our directors werecommon stock on the NYSE on such date (or the business day immediately preceding December 31st if such date should fall on a weekend). Any change in compliancethe value of the shares of our common stock during the subsequent year does not affect the amount of stock a director should hold during that year pursuant to the Ownership Requirement. If the value of the shares of our common stock decreases during a particular year, each director has until the next Determination Date to acquire any additional shares needed to meet the Ownership Requirement. When a non-employee director is newly appointed to the Board, that director shall have a period of three years to accumulate the shares required to satisfy these ownership guidelines. In addition, in the event the annual retainer increases, the NCG Committee will recommend an appropriate period of time for each non-employee director to acquire any additional shares needed to satisfy the Ownership Requirement.
For purposes of determining ownership, the following is included in determining whether a director has satisfied the Ownership Requirement: (i) shares of our common stock owned individually, either directly or indirectly, including vested and unvested restricted stock awards and restricted stock units (RSUs), or shares acquired upon the exercise of stock options; and (ii) shares of our common stock owned jointly or separately by a spouse, domestic partner and/or minor children, directly or indirectly. No other rights to acquire shares of our common stock (including stock options or similar rights) are considered shares of our common stock owned for purposes of meeting the Ownership Requirement.
Should a non-employee director at any time following the calendar year’s Determination Date and before the the next year’s Determination Date cease to comply with thesethe Ownership Requirement, the NCG Committee, in its sole discretion, may review and address any such shortfall in ownership as it deems appropriate.
The Board has also adopted stock ownership guidelines.

We do not have specific equity or other security ownership requirements or guidelines for executive officers. However, given management’s significant equity stakeour Chief Executive Officer. These requirements are discussed in the Company, we do not believe ownership guidelines are needed at this time.

greater detail under Executive Compensation.

ANTI-HEDGING AND ANTI-PLEDGING POLICY

The Board has approved an anti-hedging and anti-pledging policy for our directors and executive officers. Under this policy, all of our executive officers and directors are prohibited from engaging in short-sales, transactions in put or call options, hedging transactions or other inherently speculative transactions in Penumbra stock or pledging Penumbra stock in any circumstance, including by purchasing Penumbra stock on margin or holding Penumbra stock in a margin account.

Further, in August 2015 Penumbra adopted a policy concerning trading in company securities (the Insider Trading Policy). The Insider Trading Policy applies to the Company’s directors, officers, and employees and includes a prohibition on engaging in any hedging transactions (including transactions involving options, puts, calls, prepaid variable forward contracts, equity swaps, collars and exchange funds or other derivatives) that are designed to hedge or speculate on any change in the market value of the Company’s equity securities.
DIRECTOR COMPENSATION

Our directors play a critical role in guiding our strategic direction and overseeing the management of Penumbra. The many responsibilities and risks and the substantial time commitment of being a director require that we provide adequate compensation commensurate with our directors’ workload and opportunity costs. Independent DirectorsOur non-employee directors receive a combination of annual cash retainers and annual refresh grants of restricted stock or restricted stock unitsRSUs in amounts that correlate to their responsibilities and levels of Board participation. Our two employee directors, Mr. Elsesser and Dr. Bose, receive no separate compensation for their service as directors.

Under the Company’s director compensation policy, which was approved by the Board in April 2017 following input from Compensia, each non-employee director receives an annual cash retainer of $40,000. The Audit Committee Chair receives an additional cash retainer of $25,000. Each non-employee director also receives an annual refresh grant of RSUs in an amount equal to three times (3x) the annual cash retainer received by the non-employee directors (currently $40,000), divided by the adjusted closing price of Penumbra’s common stock on the date of the grant, rounded up or down to the nearest whole share. The annual refresh grants vest over one year in equal quarterly installments on the last day of each calendar quarter, subject to each director’s continued service on the Board through the vesting date. Upon joining the Board, each non-employee director receives an initial grant of RSUs in an amount equal to three times (3x) the annual cash retainer received by non-employee directors (currently $40,000), divided by the adjusted closing price of Penumbra’s common stock on the date of the grant, rounded up or down to the nearest whole share. The initial grants vest over four years in equal quarterly installments beginning on the last day of the calendar quarter in which the director joined the Board, subject to the director’s continued service on the Board through the vesting date.

If the stockholders fail to ratify the selection, the Board will reconsider whether or not to retain Deloitte.

We arenot asking for any additional shares under the 2014 Equity Incentive Plan or any other modification to the 2014 Equity Incentive Plan.

Summary of Material Features of the 2014 Equity Incentive Plan

Stock awards. The 2014 Equity Incentive Plan provides for the grant of incentive stock options (ISOs), nonstatutory stock options (NSOs), stock appreciation rights, restricted stock, restricted stock units, performance awards and other awards (collectively, Awards). ISOs may be granted only to employees of the Company or any parent or subsidiary of the Company. All other Awards may be granted to employees, directors and consultants. 207 employees, directors and consultants received awards under the 2014 Equity Incentive Plan in 2015.

Shares subject to the 2014 Equity Incentive Plan. The aggregate number of shares of our common stock initially reserved for issuance pursuant to Awards under the 2014 Equity Incentive Plan after our IPO was 3,000,000, plus up to 2,203,534 shares of common stock subject to stock options or similar awards previously granted under the Penumbra, Inc. 2005 Stock Plan (the 2005 Plan) and the Penumbra, Inc. 2011 Equity Incentive Plan (the 2011 Plan) that expire or otherwise terminate without having been exercised in full and shares of common stock issued pursuant to awards granted under the 2005 Plan and the 2011 Plan that are forfeited to or repurchased by the Company. In addition, there were 1,911,709 outstanding awards under the 2014 Equity Incentive Plan at the time of our IPO. If an Award granted under the 2014 Equity Incentive Plan is forfeited back to us because of the failure to meet a contingency or condition required to vest, such shares will become available for subsequent issuance under the 2014 Equity Incentive Plan. In addition, shares withheld to satisfy income or employment withholding taxes and shares used to pay the exercise price of a stock option will become available for the grant of new Awards under the 2014 Equity Incentive Plan.

Automatic increase in share reserve.The number of shares available for issuance under the 2014 Equity Incentive Plan increases automatically on the first day of each fiscal year of the Company beginning with the 2016 fiscal year and ending with the 2025 fiscal year, in an amount equal to the least of (i) 2,500,000 shares,

(ii) 5% of the outstanding shares on the last day of the immediately preceding fiscal year or (iii) such number of shares determined by the Board, to the extent allowed by Section 422 of the Code, and the regulations promulgated thereunder. On January 1, 2016, the number of shares available for issuance under the 2014 Equity Incentive Plan automatically increased by 1,494,893 shares.

Section 162(m) Limits on Awards.The maximum number of shares with respect to which any Awards may be granted to any one participant in any calendar year is (a) 5,000,000 in the case of stock options and stock appreciation rights, (b) 2,000,000 in the case of stock-based performance awards, and (c) $10,000,000 in the case of cash-based performance Awards.

Limitations on Non-Employee Awards. No non-employee director may be granted, in any calendar year, (i) stock-based Awards with a grant date fair value of more than $1,000,000 (increased to $2,000,000 in connection with his or her initial year of service); and (ii) cash-based Awards with a grant date fair value of more than $1,000,000 (increased to $1,500,000 in connection with his or her initial year of service).

Administration. Our Board, or one or more duly authorized committees thereof, have the authority to administer the 2014 Equity Incentive Plan (in such capacity, the Committee). Subject to the terms of the 2014 Equity Incentive Plan, the Committee determines recipients, dates of grant, the numbers and types of Awards to be granted and the terms and conditions of the Awards, including the period of their exercisability and vesting schedule applicable to an Award. Subject to the limitations set forth below, the Committee will also determine the exercise price, strike price or purchase price of Awards granted and the types of consideration to be paid for the Award. The Committee has the authority to modify outstanding awards under the 2014 Equity Incentive Plan. Subject to the terms of the 2014 Equity Incentive Plan, the Committee has the authority to extend the post-termination exercisability period of option awards and to extend the maximum term of an option award. To the extent that the Committee determinesadvisory, it to be desirable to qualify Awards granted hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, the 2014 Equity Incentive Plan will be administered by a committee of two or more “outside directors” within the meaning of Section 162(m) of the Code.

Stock Options. ISOs and NSOs are granted pursuant to stock option agreements adopted by the Committee. The Committee determines the exercise price for a stock option, within the terms and conditions of the 2014 Equity Incentive Plan, provided that the exercise price of a stock option cannot be less than 100% of the fair market value of our common stock on the date of grant. In the case of an ISO granted to an employee who owns stock representing more than 10% of the voting power of all classes of our stock or any parent or subsidiary of us, the exercise price will be no less 110% of the fair market value on the date of the grant. Options vest at the rate specified by the Committee. At the time an option is granted, the Committee will fix the period within which the option may be exercised and will determine any conditions that must be satisfied before the option may be exercised. No ISOs may be issued more than ten years following the earlier of (i) the date of adoption or (ii) the most recent date of approval of the 2014 Equity Incentive Plan by the Company’s stockholders, except as permitted by Section 422 of the Code.

The Committee determines the term of stock options granted under the 2014 Equity Incentive Plan, up to a maximum of ten years. In the case of an ISO granted to an employee who owns stock representing more than 10% of the voting power of all classes of our stock or the stock of any of our parents or subsidiaries, the maximum term will be 5 years. Unless the terms of an option holder’s stock option agreement provide otherwise, if an option holder’s service relationship with us ceases for any reason other than disability or death, the option holder may generally exercise any vested options for a period of three months following the cessation of service or within such longer or shorter period of time as specified in the Award agreement. If an option holder’s service relationship with us ceases due to disability or death, the option holder or a beneficiary may generally exercise any vested options within six months following termination or within such longer or shorter period of time as is specified in the Award agreement. In no event may an option be exercised beyond the expiration of its term.

Acceptable consideration for the purchase of common stock issued upon the exercise of a stock option will be determined by the Committee and may include (i) cash, (ii) check, (iii) promissory note, (iv) other shares, (v) a broker-assisted cashless exercise, (vi) net exercise, (vii) such other consideration and method of payment for the issuance of shares to the extent permitted by applicable laws, or (viii) combination of the foregoing methods of payment.

Unless the Committee provides otherwise, options generally are not transferable except by will or by the laws of descent and distribution. An option holder may designate a beneficiary, however, who may exercise the option following the option holder’s death.

Stock Appreciation Rights. The 2014 Equity Incentive Plan permits the grant of stock appreciation rights. Stock appreciation rights give recipients the right to acquire a specified number of shares of stock at a predetermined price. The terms of any stock appreciation rights granted under the 2014 Equity Incentive Plan will be determined by the Committee in the Award agreement evidencing the Award, including the number of shares, exercise price, expiration date and other terms.

Restricted Stock and Restricted Stock Units. The 2014 Equity Incentive Plan permits the grant of restricted stock and/or restricted stock units. Restricted stock awards are grants of shares of our common stock. Restricted stock units represent the right to receive shares of our common stock (or a cash amount equal to the value of our common stock) on future specified dates. The terms of the restricted stock and/or restricted stock units granted under the 2014 Equity Incentive Plan are determined by the Committee in the Award agreement evidencing the Award, including the number of shares, period of restriction or vesting schedule, and other terms.

Performance Awards. The 2014 Equity Incentive Plan permits the grant of performance awards. Performance awards may be denominated as a cash amount, number of shares, or combination thereof, and may be earned upon achievement or satisfaction of performance conditions specified by the Committee, at its discretion, subject to the terms of the 2014 Equity Incentive Plan. The Committee may specify another award as a performance award by conditioning the right of a participant to exercise or have it settled upon achievement or satisfaction of such performance conditions as may be specified by the Committee.

If the Committee intends that a performance award be considered qualified performance-based compensation under Section 162(m) of the Code, such performance award will include a pre-established formula such that payment, retention or vesting of the award is subject to achievement of a level or levels of, or increases in, in each case as determined by the Committee, one or more of the following performance measures with respect to the Company: net sales; revenue; revenue growth or product revenue growth; operating income (before or after taxes); pre- or after-tax income or loss (before or after allocation of corporate overhead and bonus); net earnings; earnings per share; net income or loss (before or after taxes); return on equity; total shareholder return; return on assets or net assets; appreciation in and/or maintenance of share price; market share; gross profits; earnings or loss (including earnings or loss before taxes, before interest and taxes, or before earnings before interest, taxes, depreciation and amortization); economic value-added models or equivalent metrics; comparisons with various stock market indices; reductions in costs; cash flow or cash flow per share (before or after dividends); return on capital (including return on total capital or return on invested capital); cash flow return on investment; improvement in or attainment of expense levels or working capital levels, including cash, inventory and accounts receivable; operating margin; gross margin; cash margin; year-end cash; debt reduction; shareholder equity; operating efficiencies; market share; customer satisfaction; customer growth; employee satisfaction; research and development achievements; manufacturing achievements (including obtaining particular yields from manufacturing runs and other measurable objectives related to process development activities); regulatory achievements (including submitting or filing applications or other documents with regulatory authorities or receiving approval of any such applications or other documents and passing pre-approval inspections (whether of the Company or the Company’s third-party manufacturer) and validation of manufacturing processes (whether the Company’s or the Company’s third-party manufacturer’s)); financial ratios, including those measuring liquidity, activity, profitability or leverage; cost of capital or assets under management; financing and other

capital raising transactions (including sales of the Company’s equity or debt securities; factoring transactions; sales or licenses of the Company’s assets, including its intellectual property, whether in a particular jurisdiction or territory or globally; or through partnering transactions); and implementation, completion or attainment of measurable objectives with respect to research, development, manufacturing, commercialization, products or projects, production volume levels, acquisitions and divestitures; factoring transactions; and recruiting and maintaining personnel. Performance criteria may be measured on an absolute or relative basis and may be established on a corporate-wide basis or with respect to a business unit or division thereof. Relative performance may be measured against a group of peer companies, a financial market index or other acceptable objective and quantifiable indices. To the extent permitted by Section 162(m) of the Code, with respect to an award intended to qualify under Section 162(m) of the Code, the Award agreement may provide that if the Committee determines that a change in the business, operations, corporate structure or capital structure of the Company, or the manner in which the Company conducts its business, or other events or circumstances render the performance objectives unsuitable, the Committee may modify the performance objectives or the related minimum acceptable level of achievement, in whole or in part, as the committee deems appropriate and equitable.

Notwithstanding any provision of the 2014 Equity Incentive Plan to the contrary, with respect to any Award intended to qualify under Section 162(m) of the Code, the Committee is not authorized to increase the amount payable under any such Award upon attainment of such pre-established formula. Performance awards intended to qualify under Section 162(m) of the Code will be settled only after the end of the relevant performance period in cash, shares, other awards, other property, net settlement, or any combination thereof, in the discretion of the Committee. The Committee will specify the circumstances in which, and the extent to which, performance awards will be paid or forfeited in the event of a participant’s termination as a service provider.

Other Awards. The 2014 Equity Incentive Plan permits the grant of such other Awards, subject to limitations under applicable law, that may be denominated or payable in, valued in whole or in part by reference to, or otherwise basedbinding on or related to, shares or factors that may influence the value of shares, including convertible or exchangeable debt securities, other rights convertible or exchangeable into shares, purchase rights for shares, awards with value and payment contingent upon performance of the Company or business units thereof or any other factors designated by the Committee. The Committee will determine the terms and conditions of such Awards. Such shares delivered pursuant to an Award in the nature of a purchase right will be purchased for such consideration, paid for at such times, by such methods and in such forms, including cash, shares, other awards, other property, or any combination thereof, as the Committee will determine.

Tax Limitations on Incentive Stock Options. The aggregate fair market value, determined at the time of grant, of our common stock with respect to ISOs that are exercisable for the first time by an option holder during any calendar year under all of our stock plans may not exceed $100,000. Options or portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of our total combined voting power or that of any of our affiliates unless (i) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant, and (2) the option is not exercisable after the expiration of five years from the date of grant. No ISO may be issued more than ten years following the earlier of (i) the date of adoption or (ii) the most recent date of approval of the 2014 Equity Incentive Plan by the Company’s stockholders, except as permitted by Section 422 of the Code.

Section 409A.With respect to Awards subject to Section 409A of the Code, the 2014 Equity Incentive Plan is intended to comply with the requirements of Section 409A of the Code and the regulations thereunder (Section 409A). In any provision of the 2014 Equity Incentive Plan or any term or condition of any Award would otherwise frustrate or conflict with this intent, the provision, term or condition will be interpreted and deemed amended so as to avoid this conflict.

Adjustments; Corporate Transactions. In the event of certain changes in our corporate structure, including any dividend or other distribution, recapitalization, stock split, reverse stock split, reorganization, merger,

consolidation, splitup, spinoff, combination, repurchase, or exchange of shares of the Company, the Committee will make appropriate adjustments to outstanding awards to prevent diminutionBoard or enlargementthe Compensation Committee of the benefitsBoard. Nevertheless, the views expressed by the stockholders, whether through this vote or potential benefits available underotherwise, are important to our management, the 2014 Equity Incentive Plan.

Merger or ChangeBoard and the Compensation Committee. Our management, Board and Compensation Committee all intend to consider the results of Control. In the event of certain corporate transactions specifiedthis vote in making determinations in the 2014 Equity Incentive Plan, including a merger or change of control, as defined in the 2014 Equity Incentive Plan, each outstanding Award will be treated as the Committee determines, without a participant’s consent, including that (i) the Awards will be continued by the Company or assumed or substituted by the succeeding corporation; (ii) the Awards will terminate; (iii) outstanding Awards will vest and become exercisable, (iv) the Awards will terminate in exchange for an amount of cash and/or property, if any, equal to the amount that would have been attained upon the exercise of the Award or realization of the rights under the Award as of the date of the transaction, (v) the replacement of any Award with rights or property selected by the Committee or (vi) any combination of the above.

In the event that the Company does not continue,future regarding our executive compensation arrangements and the successor corporation does not assume or substituteCompany’s executive compensation program, policies and practices.

Advisory approval of this proposal requires the Award or portion thereof, then with respect such Award (or portion thereof), the participant will fully vest in and have the right to exercise allvote of his or her outstanding options and stock appreciation rights and all restrictions on restricted stock and restricted stock units will lapse and, with respect to Awards with performance-based vesting (including performance awards), unless otherwise provided in an Award agreement, performance goals will be deemed achieved at 100% of the target levels. The Committee is not obligated to treat all stock Awards, even those that are of the same type, in the same manner. Under the 2014 Equity Incentive Plan, a change of control is generally (i) the acquisition by a person or entity of more than 50% of our combined voting power other than by private financing that is approved by the Board, (ii) if we are public, the date on which a majority of the Board has been replaced during any twelve-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of appointment or election; or (iii) change in ownership of a substantial portion of our assets.

Amendment and Termination. The 2014 Equity Incentive Plan will continue in effect until terminatedshares cast by the Board. The Committee has the authorityholders of shares present in person or represented by proxy and entitled to amend or alter the 2014 Equity Incentive Plan, provided that such action does not materially impair the existing rights of any participant without such participant’s written consent.

Tax Aspects under the Code

The following is a summary of the principal federal income tax consequences of certain transactions under the 2014 Equity Incentive Plan. It does not describe all federal tax consequences under the 2014 Equity Incentive Plan, nor does it describe state or local tax consequences. Participants in the 2014 Equity Incentive Plan should review the current tax treatment with their individual tax advisorsvote at the time of grant, exercise or any other transaction relating to an Award or the underlying shares.

ISOs. No taxable income is generally realized by the optionee upon the grant or exercise of an ISO. If shares of common stock issued to an optionee pursuant to the exercise of an ISO are sold or transferred after two years from the date of grant and after one year from the date of exercise, then (i) upon sale of such shares, any amount realized in excess of the option price (the amount paid for the shares) will be taxed to the optionee as a long-term capital gain, and any loss sustained will be a long-term capital loss, and (ii) the Company will not be entitled to any deduction for federal income tax purposes. The exercise of an ISO will give rise to an item of tax preference that may result in alternative minimum tax liability for the optionee. If shares of common stock acquired upon the exercise of an ISO are disposed of prior to the expiration of the two-year and one-year holding periods described above (a disqualifying disposition), generally (i) the optionee will realize ordinary income in the year of disposition in an amount equal to the excess (if any) of the fair market value of the shares of common stock at exercise (or, if less, the amount realized on a sale of such shares of common stock) over the exercise price thereof and (ii) the Company will be entitled to deduct such amount. Special rules apply where all or a portion of the exercise price of the ISO is paid by tendering shares of common stock.

If an ISO is exercised at a time when it no longer qualifies for the tax treatment described above, the option is treated as an NSO. Generally, an ISO will not be eligible for the tax treatment described above if it is exercised more than three months following termination of employment (or one year in the case of termination of employment by reason of disability). In the case of termination of employment by reason of death, the three-month rule does not apply.

NSOs. No income is realized by the optionee at the time the option is granted. Generally, (i) at exercise, ordinary income is realized by the optionee in an amount equal to the difference between the option price and the fair market value of the shares of common stock on the date of exercise, and the Company receives a tax deduction for the same amount and (ii) at disposition, appreciation or depreciation after the date of exercise is treated as either short-term or long-term capital gain or loss depending on how long the shares of common stock have been held. Special rules apply where all or a portion of the exercise price of the NSO is paid by tendering shares of common stock. Upon exercise, the optionee will also be subject to Social Security taxes on the excess of the fair market value over the exercise price of the option.

Other Awards. The Company generally will be entitled to a tax deduction in connection with an Award under the 2014 Equity Incentive Plan in an amount equal to the ordinary income realized by the participant at the time the participant recognizes such income. Participants typically are subject to income tax and recognize such tax at the time that an Award is exercised, vests or becomes non-forfeitable, unless the Award provides for a further deferral.

Parachute Payments. The vesting of any portion of an option or other Award that is accelerated due to the occurrence of a change in control (such as a sale event) may cause a portion of the payments with respect to such accelerated Awards to be treated as “parachute payments,” as defined in the Code. Any such parachute payments may be non-deductible to the Company, in whole or in part, and may subject the recipient to a non-deductible 20% federal excise tax on all or a portion of such payment (in addition to other taxes ordinarily payable).

Limitation on Deductions. Under Section 162(m) of the Code, the Company’s deduction for certain awards under the 2014 Equity Incentive Plan may be limited to the extent that the chief executive officer or other executive officer whose compensation is required to be reported in the summary compensation table (other than the principal financial officer) receives compensation in excess of $1 million a year (other than performance-based compensation that otherwise meets the requirements of Section 162(m) of the Code). The 2014 Equity Incentive Plan is structured to allow certain awards to qualify as performance-based compensation.

Stock Price

On April 21, 2016, the closing price of our common stock as reported by the NYSE was $54.40.

Plan Benefits

Because the grant of awards under the 2014 Equity Incentive Plan is within the discretion of the Board, or one or more duly authorized committee thereof, and dependent upon individual and corporate performance, among other factors, it is not possible to determine at this time the amount or dollar value to be received by a person or group under the 2014 Equity Incentive Plan.

The Board believes that it is in the Company’s best interest and in the best interest of the Company’s stockholders to ratify the 2014 Equity Incentive Plan to allow the Company to continue to grant equity awards under this plan. The Company’s Named Executive Officers have an interest in this proposal as they are eligible to receive awards under the 2014 Equity Incentive Plan.

EXECUTIVE COMPENSATION

Our Named Executive Officers (NEOs)

COMPENSATION DISCUSSION AND ANALYSIS
The following Compensation Discussion and Analysis (CD&A) provides information about our 2018 compensation program for fiscal 2015, which consist ofthe individuals who served as our principal executive officer, principal financial officer and three other most highly-compensated executive officers as of December 31, 2018, or the Named Executive Officers (whom we refer to in this discussion as our NEOs), each of whose compensation is set forth in the Summary Compensation Table and the next two most highly-compensated executives, are:

other compensation tables included in this proxy statement:
Adam Elsesser, our Chairman, President and Chief Executive Officer;

Sri Kosaraju, our Chief Financial Officer and Head of Strategy;
Lynn Rothman, our Executive Vice President and Chief Business Officer;

Arani Bose, M.D., our Chief Innovator; and
Daniel Davis, our Chief Commercial Officer and 2018 President, North America.America (as of January 21, 2019, the role of President, North America no longer exists; Mr. Davis is continuing in his role as Chief Commercial Officer and in that capacity no longer serves as an executive officer of the Company).

This CD&A also discusses our executive compensation philosophy; decisions involving our executive team, including the NEOs, with respect to compensation paid for 2018; the role of Compensia, our compensation consultant; the individual components of our executive compensation program; and certain other policies affecting executive compensation at Penumbra.
Executive Summary

2018 Executive Compensation Highlights
For the year ended December 31, 2018, the key highlights of our compensation program included:
Below Market CEO Total Cash Compensation. Throughout his tenure as our Chief Executive Officer, Mr. Elsesser has expressed a preference to our Compensation Committee that his cash compensation be modest so we could invest in other areas of the business. Mr. Elsesser maintained this preference in fiscal year 2018 and was not granted any new equity grant or cash compensation increases. As such, his total cash compensation is below the competitive market 10th percentile.
Below Market Executive Officer Total Cash Compensation. Because we generally do not pay bonuses or other short-term cash incentive compensation, total cash compensation levels approximated or were below the competitive market 25th percentile for all of our executive officers other than Mr. Davis, whose total cash compensation level approximated the competitive market 45th percentile, and Ms. Rothman, whose total cash compensation level approximated the competitive market 75th percentile.
Peer Group. We modified our compensation peer group to add six new companies and remove five former members of the compensation peer group. Two of the removals were due to acquisition activity; the remaining changes to the compensation peer group were made to make our compensation peer group consistent with the updates to compensation peer group inclusion criteria, which reflected changes in our revenue, market cap and growth profile.
Increases to Base Salary. Our NEOs have not received increases to base salary since 2015. In June 2018 we increased the base salary of two of our NEOs, Mr. Kosaraju and Ms. Rothman, from $500,000 to $600,000 as a result of a review of their prior year’s base salary relative to the competitive market and after consideration of the increased scale and complexity of the Company.

29


Short-Term Incentive Compensation Award. With one exception, our NEOs have not received cash bonus or other short-term incentive compensation since 2015. In February 2019 we granted a cash bonus to Mr. Davis that was based on his responsibilities over the 2018 performance of our North American sales team.
Equity Awards. With one exception, our NEOs have not received equity award grants since 2015. In 2018 we granted an emerging growthequity award to Mr. Davis, who was granted an equity award in the form of RSUs for retention purposes.
Executive Compensation Philosophy
Our Board and Compensation Committee maintain a simple structure for our executive compensation program focused on base salary and equity ownership. We pay our NEOs cash compensation in the form of a base salary that is at the higher end of the competitive market, but because we generally do not pay bonuses or other cash or equity incentive compensation, our NEOs receive total executive cash compensation levels that are with limited exceptions at the lower end of the competitive market.
We are confident that our streamlined compensation program aligns with our culture of cooperation and that it incentivizes our NEOs to work for the overall long-term good of the Company.
The Compensation Committee continually reviews our compensation philosophy to determine whether any changes to our current philosophy are required going forward to reward, incentivize, and retain our executive officers, or for other purposes.
Executive Compensation Philosophy, Objectives, Design and Components

It is critical to accomplishing our business objectives that we attract and retain talented executives whose skills and expertise enable them to contribute to our long-term success. As such, the principle objectives of our executive compensation program are to fairly reward, incentivize, and retain members of our executive team so that they perform in a manner that aligns their long-term interests with those of the Company and our stockholders. The following table identifies the main elements of our executive compensation program, the reasons for each, and the key features of each element within our executive compensation program:

ElementReason for Providing ElementKey Features
Base SalaryProvide our NEOs a competitive fixed level of cash compensation for their services based on their knowledge, skills, and experienceReviewed annually for market competitiveness. Typically we do not make annual increases to the base salaries of our NEOs.
Short-Term Cash Incentive CompensationEncourage our NEOs to achieve short-term individual and company goals that drive our growthWe do not have an established annual program of paying cash incentive compensation to our NEOs. However, we continually evaluate whether short-term cash incentive compensation is warranted. In 2018 we paid short-term cash incentive compensation to one NEO based on his particular responsibilities.
Long-Term Equity AwardsProvide long-term retention and incentives to our NEOs that align their interests with our stockholders’ interestsWe do not have an established annual program of awarding equity grants to our NEOs. We continually evaluate whether long-term equity awards are needed for retention, interest alignment, or other purposes. Only one NEO has received long-term equity awards since 2015.


30


Since our founding in 2004, we have optedconsistently maintained a transparent and simple executive compensation program that fosters an ownership mentality by emphasizing long-term equity compensation coupled with cash compensation in the form of a base salary that meets current needs. The primary components of the compensation programs for our NEOs are base salary and equity awards in the form of stock options, and restricted stock and restricted stock unit (RSU) awards, all subject to time-based vesting. Our 2014 Equity Incentive Plan allows us to grant, and we may consider granting, performance awards as an additional component of compensation in the future. To date, we have not established a practice of granting equity awards annually or on any other regular basis.

We are confident that our executive compensation program aligns with our culture of cooperation, and incentivizes our NEOs to work for the overall long-term good of the Company. We believe that short-term incentive compensation or other cash bonus programs can result in individuals adapting their conduct to meet specific short-term goals, the achievement of which may have unintended consequences over the long term. Moreover, differences in compensation resulting from short-term incentive compensation and other cash bonus programs can create distractions that are contrary to our culture of cooperation.

We pay our NEOs cash compensation in the form of a base salary that is at the higher end of the competitive market (at or above the market 90th percentile for all of our executive officers as of February 2018). However, because we generally do not pay bonuses or other cash or equity incentive compensation, our total executive cash compensation levels are with limited exceptions at the lower end of the competitive market (below the 25th percentile for all of our executive officers other than Mr. Davis, whose total cash compensation level approximated the 45th percentile, and Ms. Rothman, whose total cash compensation level approximated the 75th percentile, as of February 2018).
Typically, we do not make annual increases to the base salaries of our executive officers. However, we increased the annual base salaries of two of our executive officers in June 2018, which was the first time we had increased the annual base salaries of any of our executive officers since 2015.
Since our IPO in September 2015, we have not granted any of our executive officers, other than Mr. Davis, equity awards or bonuses or other cash incentive compensation. While we constantly evaluate compensation of our executive officers to reward, incentivize and retain them as appropriate, the Compensation Committee concluded that, with the exception of the grant of an equity award for retention and short-term incentive compensation based on his responsibilities over the 2018 performance of our North American sales team, both of which were awarded to Mr. Davis, no additional equity grants or other short-term incentive compensation were necessary in 2018.
The Compensation Committee will continue to review our compensation philosophy to determine whether any changes to our current philosophy are required going forward to reward, incentivize, and retain our executive officers, or for other purposes.
2018 Say-on-Pay Vote and Stockholder Engagement

At the 2018 Annual Meeting, approximately 99% of the stockholders voting at the meeting approved the compensation paid to our NEOs in 2017. Although the vote was non-binding, the Compensation Committee believes this level of approval indicates that stockholders strongly support our executive compensation program and policies. Accordingly, the Company has substantially maintained the same approach to executive compensation for 2018.

The Company carefully considers stockholder feedback regarding our executive compensation program. Our senior management team, including our Chief Executive Officer and Chief Financial Officer and Head of Strategy, regularly interacts with our stockholders throughout the year on a number of matters, including executive compensation. Through these and other outreach efforts, we believe we can understand our stockholders’ opinions and concerns on executive compensation and gather and convey stockholder views and comments directly to the Compensation Committee and the rest of the Board. For additional information concerning our stockholder outreach efforts, please refer to the section entitled “Stockholder Communications with the Board of Directors.

The Compensation Committee will consider the results of this year’s say-on-pay proposal, as well as feedback from our stockholders, when making future executive compensation decisions.

Roles of Compensation Committee, Management and Compensation Consultant

Role of Compensation Committee. The Compensation Committee charter requires the Compensation Committee to review and approve the compensation of our Chief Executive Officer and each of our other executive officers and to review and evaluate our executive compensation and benefits programs and policies in general. In making its determination about our compensation and benefits programs and policies, the Compensation Committee considers a number of factors, including the recruitment, development, promotion, retention and compensation of executive officers and other employees of the Company; the recommendations of the Chief Executive Officer (other than with respect to his own compensation); current and past total direct compensation; current and past equity ownership; competitive market data and analysis provided by the Compensation Committee’s compensation consultant; the Company’s performance and each executive officer’s impact on such performance; our operational goals; internal equity pay considerations; the performance of our common stock; and any other factors that it deems appropriate, with no one factor being determinative. The Compensation Committee also reviews and evaluates our current compensation philosophy, with input from our management and Compensia (including the development of a comparative group of medical device companies to use as our peer group for compensation decisions), to determine whether any changes to our current philosophy are required going forward.

For additional information on the Compensation Committee, see the section titled “Information Regarding Committees of the Board of DirectorsCompensation Committee” elsewhere in this proxy statement.

Role of Management. In 2018, members of management, including our Chief Executive Officer, our Chief Financial Officer and Head of Strategy, and our Executive Vice President and General Counsel, worked with the Chair of the Compensation Committee as well as the members of the Compensation Committee to develop our executive compensation program for the year. Our Chief Executive Officer, our Chief Innovator, our Executive Vice President and General Counsel, and our Vice President and Deputy General Counsel attended Compensation Committee meetings as appropriate. Our Chief Executive Officer did not participate in the discussion and decisions relating to his own compensation in 2018.

Role of Compensation Consultant. The Compensation Committee is authorized to engage its own advisers to assist it in performing its duties, and the Company pays the fees charged by such advisors. Since 2015, the Compensation Committee has engaged Compensia, a national compensation consulting firm, to assist the Compensation Committee in discharging its responsibilities by providing information on competitive market compensation practices, including market data on executive compensation, our non-employee director compensation program, compensation trends and developments, and supplying such other information and recommendations as the Compensation Committee may from time to time to request. In 2018, Compensia worked with the Compensation Committee to develop a peer group against which to compare the Company’s executive and director compensation programs and prepared reports analyzing the Company’s executive and board compensation structures against the competitive market.

Compensation Adjustments and Peer Group Process

We generally review our compensation practices on an annual basis over the course of several meetings of the Compensation Committee and the Board. The first step in the process is for the Compensation Committee, with the support of Compensia and management, to review the composition of the peer group. In connection with its analysis of our executive and director compensation programs, for 2018, Compensia collected and analyzed compensation data from a comparator group of health care equipment and health care supply companies approved by the Compensation Committee (the “peer group”).

The companies in the peer group are selected based on various criteria including size, market capitalization, stage of development, product revenue and product focus. The criteria used to select the peer group for 2018 was drawn from health care equipment and health care supply companies:

with revenue generally between $196 million and $785 million;


32


with market capitalization generally between $1.2 billion and $18.5 billion; and

headquartered in the United states.
The companies comprising the 2018 peer group (the 2018 Peer Group) were as follows:
Abaxis(1)
InogenNevro
ABIOMEDInsulet
NxStage Medical(1)
AtriCureMasimoQuidel
CryoLifeMedidata SolutionsTeladoc Health
DexComMerit Medical SystemsVarex Imaging
GlaukosNeogenVeeva Systems

(1)Abaxis was acquired in 2018 and NxStage Medical was acquired in 2019. However, compensation information was available at the time of Compensia’s 2018 review and analysis so they were included in our 2018 Peer Group.
We review and make changes to our peer group from time to time to ensure that the peer group companies satisfy our selection criteria. In comparison to the 2017 peer group:

Cynosure, Vascular Solutions, and ZELTIQ Aesthetics were removed as a result of acquisition activity;
Endologix and ICU Medical were removed based on the updated inclusion criteria; and
Glaukos, Medidata Solutions, Merit Medical Systems, Quidel, Teladoc Health, and Varex Imaging were added based on the updated inclusion criteria.

As of February 2018, as compared to the 2018 Peer Group, we were at the 40th percentile for revenue for the preceding four quarters, at approximately the 55th percentile for market capitalization, and at approximately the 75th percentile for one-year revenue growth.

The Compensation Committee uses the competitive market data provided by Compensia as a reference point, but does not believe it necessary at this stage to target any specific percentile or range of percentiles for cash, equity or total compensation for our executive officers relative to the peer group. The Compensation Committee believes the data provided by Compensia provides a useful tool in its deliberations on executive compensation.

Principal Elements of Compensation

With one exception (as described below), the 2018 compensation of our NEOs and our other executive officers consisted entirely of base salary. Only one of our NEOs received an RSU award and performance-based compensation during 2018, and none of our NEOs received any stock option or other equity awards during 2018. The mix and amount of compensation elements has been and will continue to be within the discretion and business judgment of our Board and Compensation Committee. The Compensation Committee considered total equity ownership and other factors, including but not limited to those described above under Role of the Compensation Committee, in making its compensation decisions, with no one factor being determinative, and concluded that with the one exception previously noted, it was not necessary to grant any equity awards to our NEOs in 2018.

Base Salary. We provide base salaries to our NEOs to compensate them for services rendered on a day-to-day basis and to provide sufficient fixed cash compensation to allow them to fund their personal and household expenses while remaining focused on their responsibilities to the Company. In June 2018, the Compensation Committee increased the annual base salaries of several of our executive officers, including two of our NEOs, Mr. Kosaraju and Ms. Rothman, each of whom received an increase in annual base salary from $500,000 to $600,000. These increases were the results of review of their prior year’s base salary relative to the competitive market and after consideration of the increased scale and complexity of the Company. This was the first time we increased the annual base salaries of any of our executive officers since 2015. We expect that the Compensation Committee will generally review base salary levels on a periodic basis and may review them more frequently, for example in connection with a promotion, changes in responsibilities, or general cost of living adjustments.


33


Annual Cash Incentive Bonuses. With one exception, the Company did not offer short-term cash incentive bonus opportunities to any of our NEOs in 2018. Rather, our Board and Compensation Committee continue to believe that our reliance on base salary and long-term incentive compensation in the form of equity awards adequately facilitates the achievement of our corporate operational goals and aligns each NEO’s interests with long-term stockholder interests.

In 2018, the exception to this approach involved our Chief Commercial Officer and 2018 President, North America, Mr. Davis, who was eligible to receive a short-term cash incentive bonus based on his responsibilities over the 2018 performance of our North American sales team. This bonus was equal to one million dollars ($1,000,000) and was awarded to Mr. Davis in February 2019.

Equity Awards. The Compensation Committee grants equity awards to our employees, including our executive officers and our NEOs, so that their long-term interests are aligned with those of our stockholders. Equity awards take the form of stock options and grants of either restricted stock or RSUs.

Stock options allow our executive officers (including our NEOs) to purchase shares of Company common stock at a price per share equal to the fair market value of our common stock on the date of grant. Our stock options generally vest 25% after one year, and then monthly over the subsequent three-year period as to the remaining shares subject to the options. Awards of restricted stock and RSUs allow our executive officers to acquire shares of our common stock on vesting. Awards of restricted stock and RSUs generally vest in four equal annual installments.

We do not have a practice of making equity awards annually or on any other regular basis. Rather, awards are generally made on joining the Company, when a merit-based award is appropriate, in connection with a promotion or other event, or for retention purposes. Awards made to our NEOs in 2018 reflect this philosophy. Only our Chief Commercial Officer and 2018 President, North America received an equity award in the form of RSUs in 2018, which was granted for retention purposes. Information about this equity award can be found in the 2018 Outstanding Equity Awards at Fiscal Year-EndTable below.

Perquisites, Retirement and Other Benefits. We generally do not provide perquisites or other personal benefits to our NEOs other than those available to our employees generally. We have established a 401(k) tax-deferred savings plan, which permits participants, including our NEOs, to make contributions by salary deduction pursuant to Section 401(k) of the Internal Revenue Code of 1986, as amended (the Code). We are responsible for the administrative costs of the 401(k) plan. We make matching contributions to the 401(k) plan up to specified limits. Three of our NEOs participated in the 401(k) plan in 2018. We provide all employees, including our NEOs, with life insurance equal to twice their annual salary to a maximum of $1,000,000, as well as with long-term disability insurance.

Our NEOs are eligible to participate in the Company’s health, dental, disability and other insurance plans on the same terms and at the same cost as such plans are available to all of the Company’s full-time employees. The Company does not have or provide any supplemental executive retirement plan or similar plan that provides for specified retirement payments or benefits. Moreover, the Company does not have or provide any defined contribution or other plan that provides for the deferral of compensation on a basis that is not tax-qualified.

Additionally, all full-time U.S. employees of the Company, including the NEOs, are eligible to participate in the Company’s 2014 Employee Stock Purchase Plan (the ESPP). Under the ESPP, no Company employee is permitted to purchase shares of common stock having a market value of more than $25,000 per calendar year, as calculated under the ESPP (or more than 2,000 shares of the Company’s common stock per purchase period if the value of all common stock purchased under the ESPP in any calendar year is less than $25,000). Employees of the Company’s non-U.S. subsidiaries are not eligible to participate in the ESPP but instead participate in the Penumbra, Inc. OUS Employee Stock Purchase Rebate Plan, which was approved by the Company’s stockholders at the 2018 annual meeting.

Severance and Change in Control Payments and Benefits. None of our current arrangements with our NEOs provide for severance or change in control-related payments or benefits. None of our NEOs is subject to an arrangement that is not terminable at will by the Company.

34



Equity awards held by our NEOs are subject to the terms of the relevant equity incentive plan and are each governed by an award agreement evidencing such award. The award agreements set forth the terms and conditions of the respective award and, among other things, describe the effect of various termination events on the vesting and delivery of unvested equity awards. The equity awards held by our employees, including our NEOs, provide that all unvested awards will vest immediately upon a change of control of the Company, subject to the grant recipient continuing to be a Service Provider (as defined in the relevant plan) through the date of such change in control.

No Gross-ups of Parachute Payments and Deferred Compensation

We did not provide any NEO with a “gross-up” or other reimbursement payment for any tax liability that he or she might owe as a result of the application of Sections 280G, 4999, or 409A of the Code during 2018, and we have not agreed and are not otherwise obligated to provide any NEOs with such a “gross-up” or other reimbursement.

Other Compensation-Related Policies

Compensation Recoupment Policy

We maintain a formal policy stating that, in the event that the Company is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws, the Company will recover from any current or former executive officer of the Company who received incentive-based compensation (cash or stock subject to performance-based vesting) during the three-year period preceding the date on which the Company is required to prepare an accounting restatement, based on the erroneous data, the excess of what would have been paid to the executive officer under the accounting restatement.

Stock Ownership Guidelines

To align our CEO’s interests with those of our stockholders, we maintain stock ownership guidelines requiring that our CEO hold Penumbra shares with a value equal to three times (3x) his base salary (the Ownership Requirement). The value of a share of the Company’s common stock is calculated as of December 31st of each calendar year (the Determination Date) based on the adjusted closing price of our common stock on the NYSE on such date (or the business day immediately preceding December 31st if such date should fall on a weekend). Any subsequent change in the value of the shares of our common stock during that year does not affect the amount of stock our CEO should hold during that year pursuant to the Ownership Requirement. If the value of the shares of our common stock decreases during a particular year, our CEO has until the next Determination Date to acquire any additional shares needed to meet the Ownership Requirement.

For purposes of determining ownership, the following shares are included in determining whether our CEO has satisfied the Ownership Requirement: (i) shares of our common stock owned individually, either directly or indirectly, including vested and unvested restricted stock awards and RSUs, or shares acquired upon exercise of stock options; and (ii) shares of our common stock owned jointly or separately by a spouse, domestic partner and/or minor children, directly or indirectly. No other rights to acquire shares of our common stock (including stock options or similar rights) are considered shares of our common stock owned for purposes of meeting the Ownership Requirement.

Should our CEO at any time following the Compliance Period and before the next Determination Date cease to comply with the Ownership Requirement, the NCG Committee, in its sole discretion, may review and address any such shortfall in ownership as it deems appropriate.
As of December 31, 2018, our CEO met his stock ownership guidelines.

Compensation Policies and Practices as they relate to Risk Management

Our Compensation Committee has reviewed our compensation-related risks, and the Compensation Committee does not believe that our compensation policies and practices encourage undue or inappropriate risk taking or create risks that are reasonably likely to have a material adverse effect on the Company.

Tax and Accounting Considerations

Deductibility of Executive Compensation

Section 162(m) of the Code limits the amount that we may deduct from our federal income taxes for remuneration paid to certain of our executive compensation disclosure rules applicableofficers to emerging growth companies pursuant to the JOBS Act, which require compensation disclosure for our principalone million dollars (U.S.$1,000,000) per executive officer per year. The exemption from the Section 162(m) deduction limit for “performance-based compensation” was repealed by the tax reform legislation signed into law on December 22, 2017, effective for taxable years beginning after December 31, 2017, unless transition relief for certain compensation arrangements in place as of November 2, 2017 is available.

While our Compensation Committee is mindful of the benefit to us of the full deductibility of compensation and will consider deductibility when analyzing potential compensation alternatives, our Compensation Committee believes that it should not be constrained by the two most highly compensatedrequirements of Section 162(m) where those requirements would impair flexibility in compensating our executive officers other thanin a manner that can best promote our principalcorporate objectives. Therefore, our Compensation Committee has not adopted a policy that requires that all compensation be deductible.

Accounting Treatment

We account for stock compensation in accordance with the authoritative guidance set forth in ASC Topic 718, which requires companies to measure and recognize the compensation expense for all share-based awards made to employees and directors, including stock options and RSUs, over the period during which the award recipient is required to perform services in exchange for the award (for executive officer.

officers, generally the four-year vesting period of the award). We estimate the fair value of stock options using the Black-Scholes option-valuation model. This calculation is performed for accounting purposes and reported in the compensation tables below.

Executive Officer Employment Arrangements

Our executive officers are employed on an at-will“at-will” basis. Mr. Elsesser, Mr. Kosaraju and Mr. Davis have entered into at-will offer letters with us that set forth the initial terms of their employment. We do not have agreements or policies that would require us to provide severance payments or benefits or change-in-control payments or benefits to our executive officers, other than the provisions under our equity plans and agreements described in the 2018 Outstanding Equity Awards at Fiscal Year-End” tableTable above.

Employee Benefit Plans

Our executive officers are entitled to participate in our equity incentive plans. All executive officers are eligible to participate in our 401(k) plan on the same terms as all other employees. We do not maintain any supplemental health or welfare plans for our NEOs.

Pension Benefits

We do not maintain any defined benefit pension plans.

Nonqualified Deferred Compensation

We do not maintain any nonqualified deferred compensation plans.

Potential Payments Upon Termination or Change in Control
None of our arrangements with our NEOs provide for severance or change in control-related payments or benefits. None of our NEOs is subject to an arrangement that is not terminable at will by the Company. Equity awards held by our NEOs, like equity awards held by all of our other employees, provide that all unvested awards will vest immediately upon a change of control of the Company, subject to the grant recipient continuing to be a Service Provider (as defined in the relevant plan) through the date of such change in control.

The table below sets forth the intrinsic value, as of December 31, 2018, the final trading day of fiscal 2018, of the unvested equity awards held by our NEOs which would accelerate under the circumstances described in the preceding paragraph. The actual amounts of payments that would be provided can only be determined at the time of

40


the change in control of the Company. Per SEC rules, the intrinsic value of accelerated options shown in the table below is the aggregate spread between $122.20, the closing price of our common stock on December 31, 2018, and the exercise prices of the accelerated options, if less than $122.20.

Transactions with Related Persons, Promoters and Certain Control Persons

Since January 1, 2015, other than one transaction with Mr. Pray which is described below under the section entitled “Indebtedness of Directors and Executive Officers”,2018, there has not been nor is there currently proposed any transaction or series of similar transactions to which we were or are to be a party in which the amount involved exceeds $120,000 and in which any director, executive officer, holder of more than 5% of our common stock, or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest other than compensation agreements and other arrangements, which are described elsewhere in this Proxy Statement. See the section entitled “Indebtedness of Directors and Executive Officers” below for a description of one transaction with Mr. Pray, one of our executive officers.

Review, Approval, and Ratification of Transactions with Related Party

Parties

Our NCG Committee has primary responsibility for reviewing and approving in advance or ratifying all related party transactions. Additionally, on at least an annual basis, the Audit Committee also reviews all identified related party transactions. In conformance with SEC regulations, we define related persons to include our executive officers, our directors and nominees to become a director of our company, any person who is known to us to be the beneficial owner of more than 5% of any class of our voting securities, any immediate family member of any of the foregoing persons, and any firm, corporation or other entity in which any of the foregoing persons is employed, is a general partner or in which such person has a 5% or greater beneficial ownership interest.

We have several processes that we use to ensure that we identify and review all related party transactions. First, each director, director nominee and executive officer is required to notify the Corporate Secretary of any transaction involving the Company and a related person, and the Corporate Secretary will present any new related party transactions to the NCG Committee at its next regularly scheduled meeting. Second, each year, we require our directors and executive officers to complete director and officer questionnaires identifying any transactions with us in which the executive officer or director or their family members have an interest.

The NCG Committee reviews related party transactions due to the potential for such transactions to create a conflict of interest. A conflict of interest occurs when an individual’s private interest interferes, or appears to interfere, with our interests. The NCG Committee will not approve or ratify a related person transaction unless it first determines that, upon consideration of all relevant information, the transaction is in, or not inconsistent with, the best interests of the Company and its stockholders. In reviewing the transaction or proposed transaction, the NCG Committee considers all relevant facts and circumstances, including without limitation the commercial reasonableness of the terms, the benefit and perceived benefit, or lack thereof, to the Company, opportunity costs of alternate transactions, the materiality and character of the related person’s direct or indirect interest, and the actual or apparent conflict of interest of the related person.

CEO Pay Ratio Disclosure
As required by Section 953(b) of Directorsthe Dodd-Frank Wall Street Reform and Executive Officers

In 2005, we made a loan to oneConsumer Protection Act, and Item 402(u) of Regulation S-K, the following presents information regarding the relationship of the annual total compensation of our executive officers, James Pray,employees and the annual total compensation of our Chief Executive Officer, Mr. Elsesser.

We identified the median employee for our 2017 pay ratio analysis using the following methodology:
We selected December 24, 2017, as the date on which to determine our median employee (the Determination Date). As of the Determination Date, we employed approximately 1,700 individuals. This population consisted of full-time, part-time, and temporary employees. In addition to the United States, the Company has employees in Canada, Australia, Brazil, Singapore, and throughout Europe.
To identify the form of a full-recourse secured promissory note inmedian employee from our employee population, we compared the amount of $85,000, to permit him to exercise stock options granted to him. This note was

secured by a stock pledge agreement covering 500,000 sharessalary, wages and fringe benefits of all of our common stock held byemployees who were employed as of the Determination Date (excluding Mr. Pray. This note accrued interestElsesser), as reflected in Box 1 of Form W-2 for 2017 (for our U.S.-based employees), and information gathered from our 2017 payroll reports from our payroll providers (for our international employees) as of the Determination Date.

Wages and salaries were annualized for those employees that were not employed for the full year of 2017. We did not make any cost-of-living adjustments in identifying the median employee. Employee pay rates in foreign currencies were converted to U.S. Dollars using exchange rates on December 31, 2017. Using this methodology we determined that our median employee was a full-time hourly employee working in our manufacturing facilities at our campus in Alameda, California.
SEC rules permit us to identify the ratemedian employee only once every three years, unless there have been changes in our employee population or employee compensation arrangements that we believe would result in a significant change in our pay ratio disclosure. There has been no change in our employee population or employee compensation arrangements that we reasonably believe would result in a significant change to our pay ratio disclosure. As a result, we decided to use the same median employee that we identified for our 2017 pay ratio disclosure.
In determining our 2018 pay ratio, we combined all elements of 2.92% per annum, with principal and interest due and payableour median employee’s compensation for 2018 using the same methodology that we used for calculating Mr. Elsesser’s total compensation shown in the 2018 Summary Compensation Table, resulting in annual total compensation of $51,611. Mr. Elsesser’s annual total compensation, as reported in the 2018 Summary Compensation Table, was $726,648. Based on January 31, 2015, provided that uponthis information, the occurrenceratio of a changethe annual total compensation of control of Penumbra, Mr. Pray would be required to pre pay principal in an amount equalElsesser to the product of the number of sharesannual total compensation of our common stockmedian employee was 14.1 to 1 for 2018.
We believe that vestedthe above pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. In addition, because the SEC rules for identifying the median employee allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as a result of such change of controlother companies may have different employment and $0.01. On April 14, 2015, the Board forgave this loan to Mr. Praycompensation practices and may utilize different methodologies, exclusions, estimates and assumptions in its entirety, including accrued and unpaid interest thereon.

Other than the foregoing, none of our directors or executive officers or associates of any director or executive officer is or at any time since January 1, 2015 has been indebted to us.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Proxy Availability Notice or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Proxy Availability Notice or other Annual Meeting Materials addressed to those stockholders. This process, which is commonly referred to as householding, potentially provides extra convenience for stockholders and cost savings for companies. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards.

This year, a number of brokers with account holders who are our stockholders will be “householding” our proxy materials. A Proxy Availability Notice or proxy materials will be delivered in one single envelope to multiple stockholders sharing an address unless contrary instructions have been received from one or more of the affected stockholders. Once you have received notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate Proxy Availability Notice or proxy materials, please notify your broker or contact Broadridge Financial Solutions, Inc. in writing: Attn: Householding Department, 51 Mercedes Way, Edgewood, NY 11717; or by telephone: (800) 542-1061. Stockholders who currently receive multiple copies of the Proxy Availability Notice or proxy materials at their address and would like to request householding of their communications should contact their broker. In addition, we will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the Proxy Availability Notice or proxy materials to a stockholder at a shared address to which a single copy of the documents was delivered.

4.Administration of the Plan.

(a)Procedure.

(i) Multiple Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the Plan.

(ii) Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards granted hereunder as “performance-based compensation” within the meaning of Section 162(m), the Plan will be administered by a Committee of two (2) or more “outside directors” within the meaning of Section 162(m).

(iii) Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3.

(i) to determine the Fair Market Value;

(ii) to select the Service Providers to whom Awards may be granted hereunder;

(iii) to determine the number of Shares to be covered by each Award granted hereunder;

(iv) to approve forms of Award Agreements for use under the Plan;

Such terms and conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine;

(vi) to institute and determine the terms and conditions of an Exchange Program;

(vii) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan;

(viii) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans and Award Agreements established for the purpose of satisfying applicable foreign laws or for qualifying for favorable tax treatment under applicable foreign laws;

(ix) to modify or amend each Award (subject to Section 20(c) of the Plan), including but not limited to the discretionary authority to extend the post-termination exercisability period of Awards and to extend the maximum term of an Option (subject to Section 6(d));

(x) to allow Participants to satisfy withholding tax obligations in a manner prescribed in Section 16;

(xi) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by the Administrator;

(xii) to allow a Participant to defer the receipt of the payment of cash or the delivery of Shares that otherwise would be due to such Participant under an Award; and

(xiii) to make all other determinations deemed necessary or advisable for administering the Plan.

(c)Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations will be final and binding on all Participants and any other holders of Awards.

5.Eligibility and Limitations.

(a)Eligibility. Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock, and Restricted Stock Units may be granted to Service Providers. Incentive Stock Options may be granted only to Employees.

(b)Outside Director Limitations. No Outside Director may be granted, in any calendar year, (i) stock-based Awards with a grant date fair value (determined in accordance with U.S. generally accepted accounting principles) of more than $1,000,000, increased to $2,000,000 in connection with his or her initial year of service) and (ii) cash-based Awards with a grant date fair value (determined in accordance with U.S. generally accepted accounting principles) of more than $1,000,000 (increased to $1,500,000 in connection with his or her initial year of service).

(c)Individual Limitations. The following limits shall apply to the amount that may be awarded to any Participant during any calendar year, subject to adjustment as provided in Section 15: (i) Options and SARs that relate to no more than 5,000,000 Shares; (B) Performance Awards that relate to no more than 2,000,000 Shares and (C) cash-based Performance Awards that relate to no more than $10,000,000.

6.Stock Options.

(a)Grant of Options. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time, may grant Options in such amounts as the Administrator, in its sole discretion, will determine.

(b)Option Agreement. Each Award of an Option will be evidenced by an Award Agreement that will specify the exercise price, the term of the Option, the number of Shares subject to the Option, the exercise restrictions, if any, applicable to the Option, and such other terms and conditions as the Administrator, in its sole discretion, will determine.

(c)Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. Notwithstanding such designation, however, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(c), Incentive Stock Options will be taken into account in the order in which they were granted, the Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted, and calculation will be performed in accordance with Code Section 422 and Treasury Regulations promulgated thereunder. No Incentive Stock Options may be issued more than ten years following the earlier of (i) the date of adoption or (ii) the most recent date of approval of this Plan by the Company’s stockholders, except as permitted by Section 422 of the Code.

(d)Term of Option. The term of each Option will be stated in the Award Agreement; provided, however, that the term will be no more than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement.

(e)Option Exercise Price and Consideration.

(i) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the exercise of an Option will be determined by the Administrator, but will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. In addition, in the case of an Incentive Stock Option granted to an Employee who owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant. Notwithstanding the foregoing provisions of this Section 6(e)(i), Options may be granted with a per Share exercise price of less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Code Section 424(a).

(ii) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised.

(iii) Form of Consideration. The Administrator will determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely of: (1) cash; (2) check; (3) promissory note, to the extent permitted by Applicable Laws, (4) other Shares, provided that such Shares have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option will be exercised and provided further that accepting such Shares will not result in any adverse accounting consequences to the Company, as the Administrator determines in its sole discretion; (5) consideration received by the Company under cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with the Plan; (6) by net exercise, (7) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws, or (8) any combination of the foregoing methods of payment.

(f)Exercise of Option.

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share.

An Option will be deemed exercised when the Company receives: (i) notice of exercise (in such form as the Administrator may specify from time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable tax withholding). Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 15 of the Plan.

Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

(ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s termination as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within three (3) months following termination, or such longer or shorter period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement) to the extent that the Option is vested on the date of termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

(iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the Participant may exercise his or her Option within six (6) months following termination, or such longer or shorter period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement) to the extent the Option is vested on the date of termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

(iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised within six (6) months following the Participant’s death, or within such longer or shorter period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement) to the extent that the Option is vested on the date of death, by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to the Participant’s death in a form acceptable to the Administrator. If no such beneficiary has been designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the laws of descent and distribution. Unless otherwise provided by the Administrator, if at the time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

7.Stock Appreciation Rights.

(a)Grant of Stock Appreciation Rights. Subject to the terms and conditions of the Plan, a Stock Appreciation Right may be granted to Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion.

(b)Number of Shares. The Administrator will have complete discretion to determine the number of Shares subject to any Award of Stock Appreciation Rights.

(c)Exercise Price and Other Terms. The per Share exercise price for the Shares that will determine the amount of the payment to be received upon exercise of a Stock Appreciation Right as set forth in Section 7(f) will be determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, the Administrator, subject to the provisions of the Plan, will have complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under the Plan.

(d)Stock Appreciation Right Agreement. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine.

(e)Expiration of Stock Appreciation Rights. A Stock Appreciation Right granted under the Plan will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(d) relating to the maximum term and Section 6(f) relating to exercise also will apply to Stock Appreciation Rights.

(f)Payment of Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation Right, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying:

(i) The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times

(ii) The number of Shares with respect to which the Stock Appreciation Right is exercised.

At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be in cash, in Shares of equivalent value, or in some combination thereof.

8.Restricted Stock.

(a)Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine.

(b)Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of Restricted Stock until the restrictions on such Shares have lapsed.

(c)Transferability. Except as provided in this Section 8 or as the Administrator determines, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction.

(d)Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock as it may deem advisable or appropriate.

(e)Removal of Restrictions. Except as otherwise provided in this Section 8, Shares of Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may determine. The Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed.

(f)Voting Rights. During the Period of Restriction, Service Providers holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise.

(g)Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock will be entitled to receive all dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If any such dividends or distributions are paid in Shares, the Shares will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid.

(h)Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan.

9.Restricted Stock Units.

(a)Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. After the Administrator determines that it will grant Restricted Stock Units, it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units.

(b)Vesting Criteria and Other Terms. The Administrator will set vesting criteria in its discretion, which, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator may set vesting criteria based upon continued employment or service and/or the achievement of Company-wide, business unit, individual or other goals, or any other basis determined by the Administrator in its discretion.

(c)Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will be entitled to receive a payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a payout.

(d)Form and Timing of Payment. Payment of earned Restricted Stock Units will be made as soon as practicable after the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may settle earned Restricted Stock Units in cash, Shares, or a combination of both.

(e)Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units will be forfeited to the Company.

10.Performance Awards. The Committee is authorized to grant Performance Awards to Participants with the following terms and conditions and with such additional terms and conditions, in either case not inconsistent with the provisions of the Plan, as the Committee shall determine:

(a) Performance Awards may be denominated as a cash amount, number of Shares or a combination thereof and are Awards which may be earned upon achievement or satisfaction of performance conditions specified by the Committee. In addition, the Committee may specify that any other Award shall constitute a Performance Award by conditioning the right of a Participant to exercise the Award or have it settled, and the timing thereof, upon achievement or satisfaction of such performance conditions as may be specified by the Committee. The Committee may use such business criteria and other measures of performance as it may deem appropriate in establishing any performance conditions. Subject to the terms of the Plan, the performance goals to be achieved during any performance period, the length of any performance period, the amount of any Performance Award granted and the amount of any payment or transfer to be made pursuant to any Performance Award shall be determined by the Committee.

(b) If the Committee intends that a Performance Award be considered qualified performance-based compenastion under Section 162(m), such Performance Award shall include a pre-established formula, such that payment, retention or vesting of the Award is subject to the achievement during a Performance Period or Performance Periods, as determined by the Committee, of a level or levels of, or increases in, in each case as determined by the Committee, one or more of the following performance measures with respect to the Company: net sales; revenue; revenue growth or product revenue growth; operating income (before or after taxes); pre- or after-tax income or loss (before or after allocation of corporate overhead and bonus); net earnings; earnings per share; net income or loss (before or after taxes); return on equity; total shareholder return; return on assets or net assets; appreciation in and/or maintenance of share price; market share; gross profits; earnings or loss (including earnings or loss before taxes, before interest and taxes, or before earnings before interest, taxes, depreciation and amortization); economic value-added models or equivalent metrics; comparisons with various stock market indices; reductions in costs; cash flow or cash flow per share (before or after dividends); return on capital (including return on total capital or return on invested capital); cash flow return on investment; improvement in or attainment of expense levels or working capital levels, including cash, inventory and accounts receivable; operating margin; gross margin; cash margin; year-end cash; debt reduction; shareholder equity; operating efficiencies; market share; customer satisfaction; customer growth; employee satisfaction; research and development achievements; manufacturing achievements (including obtaining particular yields from manufacturing runs and other measurable objectives related to process development activities); regulatory achievements (including submitting or filing applications or other documents with regulatory authorities or receiving approval of any such applications or other documents and passing pre-approval inspections (whether of the Company or the Company’s third-party manufacturer) and validation of manufacturing processes (whether the Company’s or the Company’s third-party manufacturer’s)); financial ratios, including those measuring liquidity, activity, profitability or leverage; cost of capital or assets under management; financing and other capital raising transactions (including sales of the Company’s equity or debt securities; factoring transactions; sales or licenses of the Company’s assets, including its intellectual property, whether in a particular jurisdiction or territory or globally; or through partnering transactions); and implementation, completion or attainment of measurable objectives with respect to research, development, manufacturing, commercialization, products or projects, production volume levels, acquisitions and divestitures; factoring transactions; and recruiting and maintaining personnel. Performance criteria may be measured on an absolute (e.g., plan or budget) or relative basis, and may be established on a corporate-wide basis or with respect to one or more business units, divisions, subsidiaries or business segments. Relative performance may be measured against a group of peer companies, a financial market index or other acceptable objective and quantifiable indices. To the extent permitted by Section 162(m), with respect to an award intended to qualify under Section 162(m), the Award Agreement may provide that if the Committee determines that a change in the business, operations, corporate structure or capital structure of the Company, or the manner in which the Company conducts its business, or other events or circumstances render the performance objectives unsuitable, the Committee may modify the performance objectives or the related minimum acceptable level of achievement, in whole or in part, as the Committee deems appropriate and equitable. Performance measures may vary from Performance Award to Performance Award, respectively, and from Participant to Participant, and may be established on a stand-alone basis, in tandem or in the alternative. The Committee shall have the power to impose such other restrictions on Awards subject to this Section as it may deem necessary or appropriate. Notwithstanding any provision of the Plan to the contrary, with respect to any Award intended to qualify under Section 162(m), the Committee shall not be authorized to increase the amount payable under any Award to which this subsection (b) applies upon attainment of such pre-established formula. Performance Awards intended to qualify under Section 162(m) will be settled only after the end of the relevant Performance Period.

(c) Settlement of Performance Awards shall be in cash, Shares, other Awards, other property, net settlement, or any combination thereof, in the discretion of the Committee.

(d) The Committee shall specify the circumstances in which, and the extent to which, Performance Awards shall be paid or forfeited in the event of a Participant’s termination as a Service Provider.

11.Other Awards. The Committee is authorized, subject to limitations under applicable law, to grant to Participants such other Awards that may be denominated or payable in, valued in whole or in part by reference to, or otherwise based on, or related to, Shares or factors that may influence the value of Shares, including

convertible or exchangeable debt securities, other rights convertible or exchangeable into Shares, purchase rights for Shares, Awards with value and payment contingent upon performance of the Company or business units thereof or any other factors designated by the Committee. The Committee shall determine the terms and conditions of such Awards. Shares delivered pursuant to an Award in the nature of a purchase right granted under this Section shall be purchased for such consideration, paid for at such times, by such methods and in such forms, including cash, Shares, other Awards, other property, or any combination thereof, as the Committee shall determine. Cash awards may also be granted pursuant to this Section.

12.Compliance With Code Section 409A. Awards will be designed and operated in such a manner that they are either exempt from the application of, or comply with, the requirements of Code Section 409A, except as otherwise determined in the sole discretion of the Administrator. The Plan and each Award Agreement under the Plan is intended to meet the requirements of Code Section 409A and will be construed and interpreted in accordance with such intent, except as otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Code Section 409A the Award will be granted, paid, settled or deferred in a manner that will meet the requirements of Code Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A.

13.Leaves of Absence/Transfer Between Locations. Unless the Administrator provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of absence. A Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or (ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed three (3) months, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then six (6) months following the first (1st) day of such leave, any Incentive Stock Option held by the Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option.

14.Limited Transferability of Awards. Unless determined otherwise by the Administrator, Awards may not be sold, pledged, assigned, hypothecated, or otherwise transferred in any manner other than by will or by the laws of descent and distribution, and may be exercised, during the lifetime of the Participant, only by the Participant.

15.Adjustments; Dissolution or Liquidation; Merger or Change in Control.

(a)Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will adjust the number and class of shares of stock that may be delivered under the Plan and/or the number, class, and price of shares of stock covered by each outstanding Award, and the Share limits set forth in Sections 3 and 5 of the Plan.

(b)Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action.

(c)Merger or Change in Control. In the event of a merger of the Company with or into another corporation or other entity or a Change in Control, each outstanding Award will be treated as the Administrator determines (subject to the provisions of the following paragraph) without a Participant’s consent, including,

without limitation, that (i) Awards will be continued by the Company or assumed, or substantially equivalent Awards will be substituted, by the acquiring or succeeding corporation (or an affiliate thereof) with appropriate adjustments as to the number and kind of shares and prices; (ii) upon written notice to a Participant, that the Participant’s Awards will terminate upon or immediately prior to the consummation of such merger or Change in Control; (iii) outstanding Awards will vest and become exercisable, realizable, or payable, or restrictions applicable to an Award will lapse, in whole or in part prior to or upon consummation of such merger or Change in Control, and, to the extent the Administrator determines, terminate upon or immediately prior to the effectiveness of such merger or Change in Control; (iv) (A) the termination of an Award in exchange for an amount of cash and/or property, if any, equal to the amount that would have been attained upon the exercise of such Award or realization of the Participant’s rights as of the date of the occurrence of the transaction (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction the Administrator determines in good faith that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment), or (B) the replacement of such Award with other rights or property selected by the Administrator in its sole discretion; or (v) any combination of the foregoing. In taking any of the actions permitted under this subsection (c), the Administrator will not be obligated to treat all Awards, all Awards held by a Participant, or all Awards of the same type, similarly.

In the event that the Company does not continue, and the successor corporation does not assume or substitute for the Award (or portion thereof), then with respect to such Award (or portion thereof), the Participant will fully vest in and have the right to exercise all of his or her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting (including Performance Awards), unless otherwise provided in an Award Agreement, all performance goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not continued, assumed or substituted in the event of a merger or Change in Control, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period.

For the purposes of this subsection (c), an Award will be considered assumed if, following the merger or Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the merger or Change in Control, the consideration (whether stock, cash, or other securities or property) received in the merger or Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit or Performance Award, for each Share subject to such Award, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the merger or Change in Control.

Notwithstanding anything in this subsection (c) to the contrary, unless otherwise provided in an Award Agreement, an Award that vests, is earned or paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals without the Participant’s consent in a manner that would be adverse to the Participant; provided, however, a modification to such performance goals only to reflect the successor corporation’s post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption.

Notwithstanding anything in this subsection (c) to the contrary, if a payment under an Award Agreement is subject to Code Section 409A and if the change in control definition contained in the Award

Agreement does not comply with the definition of “change of control” for purposes of a distribution under Code Section 409A, then any payment of an amount that is otherwise accelerated under this Section will be delayed until the earliest time that such payment would be permissible under Code Section 409A without triggering any penalties applicable under Code Section 409A.

16.Tax Withholding.

(a)Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise or vesting or settlement thereof, as applicable), the Company will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to be withheld with respect to such Award (or exercise or vesting or settlement thereof, as applicable).

(b)Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld, (iii) delivering to the Company already-owned Shares having a Fair Market Value equal to the statutory amount required to be withheld, provided the delivery of such Shares will not result in any adverse accounting consequences, as the Administrator determines in its sole discretion, or (iv) selling a sufficient number of Shares otherwise deliverable to the Participant through such means as the Administrator may determine in its sole discretion (whether through a broker or otherwise) equal to the amount required to be withheld.

(c)Section 409A of the Code. With respect to Awards subject to Section 409A of the Code, the Plan is intended to comply with the requirements of Section 409A of the Code and the regulations thereunder (“Section 409A”), and the provisions of the Plan and any Award Agreement shall be interpreted in a manner that satisfies the requirements of Section 409A, and the Plan shall be operated accordingly. If any provision of the Plan or any term or condition of any Award would otherwise frustrate or conflict with this intent, the provision, term or condition will be interpreted and deemed amended so as to avoid this conflict.

17.No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right with respect to continuing the Participant’s relationship as a Service Provider with the Company or any Parent or Subsidiary of the Company, nor will they interfere in any way with the Participant’s right or the right of the Company, or any Parent or Subsidiary of the Company, to terminate such relationship at any time, with or without cause, to the extent permitted by Applicable Laws.

18.Date of Grant. The date of grant of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant within a reasonable time after the date of such grant.

19.Term of Plan. The Plan will continue in effect until terminated by the Board.

20.Amendment and Termination of the Plan.

(a)Amendment and Termination. The Administrator may at any time amend, alter, suspend or terminate the Plan.

(b)Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws.

(c)Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the

Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination.

21.Conditions Upon Issuance of Shares.

(a)Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares will comply with Applicable Laws.

(b)Investment Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

22.Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority will not have been obtained.

23.Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.
