PROXY STATEMENT

FOR THE ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON MAY 24, 2018

Q UESTIONS AND A NSWERS

Why have these proxy materials been made available to me?

We made these proxy materials available to you on the Internet and/or we have delivered printed versions of these materials to you by mail, because the Board of Directors of Senomyx, Inc. is soliciting your proxy to vote at its 2018 Annual Meeting of Stockholders, including at any adjournments or postponements of the meeting. You are invited to attend the annual meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return the accompanying proxy card or you may elect to vote your shares using the Internet, by going to http://proxy2018.senomyx.com and following the instructions provided on the website.

Why did I receive a notice in the mail regarding the Internet availability of proxy materials?

As permitted by rules adopted by the Securities and Exchange Commission, or SEC, we are making this proxy statement and our annual report available to stockholders electronically via the Internet. Accordingly, we are sending by mail a Notice of Internet Availability of Proxy Materials to our stockholders of record containing instructions on how to access the proxy materials and vote by proxy over the Internet. All stockholders have the ability to access the proxy materials on a website referred to in the Notice of Internet Availability of Proxy Materials or request the delivery of a printed set of proxy materials. If you received a Notice of Internet Availability of Proxy Materials by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials included in the Notice of Internet Availability of Proxy Materials.

We intend to mail the Notice of Internet Availability of Proxy Materials (or this proxy statement, our annual report and a proxy card to stockholders with pre-existing requests to receive paper copies of such materials) on or about April 9, 2018 to all stockholders of record entitled to vote at the annual meeting.

Who can vote at the annual meeting?

Only stockholders of record at the close of business on March 28, 2018, the record date for the annual meeting, will be entitled to vote at the annual meeting. At the close of business on the record date, there were 48,304,277 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If at the close of business on the record date, your shares were registered directly in your name with our transfer agent, Computershare Shareowner Services, then you are a stockholder of record. As a stockholder of record, you may vote in person at the meeting or vote by proxy using the accompanying proxy card. Whether or not you plan to attend the meeting, we urge you to fill out and return the accompanying proxy card or vote by proxy through the Internet to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Agent

If at the close of business on the record date, your shares were held, not in your name, but rather in an account at a brokerage firm, bank or other agent, then you are the beneficial owner of shares held in “street name” and these proxy materials or the Notice of Internet Availability of Proxy Materials are being forwarded to you by your broker, bank or other agent. The broker, bank or other agent holding your account is considered to be the stockholder of record for purposes of voting at the annual meeting.

As a beneficial owner, you have the right to direct your broker, bank or other agent on how to vote the shares in your account. However, since you are not the stockholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy issued in your name from your broker, bank or other agent.

How can I attend the annual meeting?

You are entitled to attend the annual meeting only if you were a stockholder at the close of business on March 28, 2018, or you hold a valid proxy to vote at the meeting. In addition, each stockholder will be asked to present valid government-issued picture identification, such as a driver’s license, before being admitted to the meeting.

For registered stockholders, an admission ticket is attached to your proxy card. Please detach and bring the admission ticket with you to the meeting.

If your shares are held in the name of your broker, bank, or other nominee, you must bring to the meeting an account statement or letter from the nominee indicating that you beneficially owned the shares on March 28, 2018, the record date for voting.

Stockholders will be admitted only upon verification of ownership.

How can I vote in person at the annual meeting?

You may vote in person at the annual meeting those shares that you hold in your name as the stockholder of record. You may vote in person shares for which you are the beneficial owner only by obtaining a legal proxy giving you the right to vote the shares from the bank, broker or other nominee that is the registered holder of your shares.

Even if you plan to attend the Annual Meeting, we recommend that you also submit your proxy or voting instructions as described below so that your vote will be counted if you later decide not to attend.

What am I voting on?

There are four matters scheduled for a vote at the annual meeting:

•

the election of the seven nominees for director set forth in Proposal 1 to hold office until our 2019 Annual Meeting of Stockholders;

•

the approval of an amendment to the Senomyx, Inc. 2004 Employee Stock Purchase Plan to increase the maximum number of shares available for sale thereunder by 2,000,000 shares;

•

the ratification of the selection by the Audit Committee of our Board of Directors of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2018; and

•

advisory approval of the compensation of our named executive officers, as disclosed in this proxy statement in accordance with SEC rules.

What if another matter is properly brought before the meeting?

The Board of Directors knows of no other matters that will be presented for consideration at the annual meeting. If any other matters are properly brought before the meeting it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

How do I vote?

For the election of directors in Proposal 1, you may either vote “For” all nominees or you may “Withhold” your vote for any nominee you specify. For Proposals 2, 3 and 4, you may vote “For” or “Against” or abstain from voting. The procedures for voting are as follows:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote in person at the annual meeting. Alternatively, you may vote by proxy through the Internet or using the accompanying proxy card. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person if you have already voted by proxy.

•

To vote in person, come to the annual meeting and request a ballot. In order to cast your vote you will need to provide satisfactory identification corresponding to our stockholder records.

•

To vote on the Internet, go to http://proxy2018.senomyx.com and follow the instructions provided on the website. In order to cast your vote, you will be asked to provide the control number from the Notice of Internet Availability of Proxy Materials or the proxy card mailed to you. Your vote must be received by 11:59 p.m. Eastern Time on May 23, 2018 to be counted.

•

To vote using the proxy card, simply complete, sign and date the accompanying proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the annual meeting, we will vote your shares as you direct. If you received a Notice of Internet Availability of Proxy Materials and would like to request a proxy card by mail, please follow the instructions contained in the Notice of Internet Availability of Proxy Materials.

Beneficial Owner: Shares Registered in the Name of Broker, Bank or Other Agent

If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should have received voting instructions with these proxy materials from that organization rather than from us. Simply complete and return the voting instructions to ensure that your vote is counted. To vote in person at the annual meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker, bank or other agent included with these proxy materials, or contact your broker, bank or other agent to request a proxy form.

We provide Internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet access, such as usage charges from Internet access providers.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of the close of business on March 28, 2018, the record date for the annual meeting.

What if I return a proxy card or otherwise vote but do not make specific choices?

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of all nominees for director, “For” the approval of an amendment to the Senomyx, Inc. 2004 Employee Stock Purchase Plan to increase the maximum number of shares available for sale thereunder by 2,000,000 shares, “For” the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm, and “For” the compensation of our named executive officers, as discussed in this proxy statement. If any other matter is properly presented at the meeting, one of the individuals named on your proxy card as your proxy will vote your shares using his or her best judgment.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

What does it mean if I receive more than one Notice of Internet Availability of Proxy Materials or proxy card?

If you receive more than one set of proxy materials, your shares may be registered in more than one name or are registered in different accounts. Please follow the voting instructions on the proxy cards in the proxy materials to ensure that all of your shares are voted.

Can I revoke or change my vote after submitting my proxy?

Yes. You can revoke your proxy and change your vote at any time before the applicable vote at the meeting. If you are the record holder of your shares, you may revoke your proxy in any one of four ways:

•

you may submit another properly completed proxy with a later date,

•

you may vote again by Internet at a later time,

•

you may send a written notice that you are revoking your proxy to our Corporate Secretary at 4767 Nexus Centre Drive, San Diego, California 92121, or

•

you may attend the annual meeting and vote in person (however, simply attending the meeting will not, by itself, revoke your proxy or change your vote).

Your most current proxy card or Internet proxy is the one that is counted.

If your shares are held by your broker, bank or other agent, you should follow the instructions provided by them.

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

To be considered for inclusion in next year’s proxy materials, a stockholder proposal must be submitted in writing by December 10, 2018, to our Corporate Secretary at 4767 Nexus Centre Drive, San Diego, California 92121. If you wish to submit a proposal at the meeting that is not to be included in next year’s proxy materials, your proposal generally must be submitted in writing to the same address no later than February 23, 2019, but no earlier than January 24, 2019. Please review our Bylaws which contains additional requirements regarding advance notice of stockholder proposals.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count, for the proposal to elect directors, “For,” “Withhold” and broker non-votes; and with respect to any other proposals, votes “For” and “Against,” abstentions and, if applicable, broker non-votes. Abstentions will be counted towards the vote total for Proposal 2, Proposal 3 and Proposal 4 and will have the same effect as “Against” votes. Broker non-votes have no effect and will not be counted towards the vote total for any proposal.

What are “broker non-votes”?

If your shares are held by your broker, bank or other agent as your nominee (that is, in “street name”), you will need to obtain a proxy form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your broker, bank or other agent to vote your shares. If you do not give instructions to your broker, bank or other agent, they can vote your shares with respect to “discretionary” items, but not with respect to “non-discretionary” items. Discretionary items are proposals considered routine under the rules of the New York Stock Exchange on which your broker, bank or other agent may vote shares held in street name in the absence of your voting instructions. Non-discretionary items are matters that may substantially affect the rights

or privileges of stockholders, such as mergers, stockholder proposals, executive compensation (including advisory stockholder votes on executive compensation) and election of directors (even if not contested). On non-discretionary items for which you do not give instructions to your broker, bank or other agent, the shares will be treated as broker non-votes.

How many votes are needed to approve each proposal?

•

For the election of directors, the seven nominees receiving the most “For” votes from the holders of shares present in person or represented by proxy and entitled to vote on the election of directors will be elected. Only votes “For” or “Withhold” will affect the outcome.

•

The amendment of our 2004 Employee Stock Purchase Plan must receive “For” votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the matter. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.

•

The ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm must receive “For” votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the matter. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.

•

Advisory approval of the compensation of our named executive officers will be considered to be approved if it receives “For” votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the matter. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if at least a majority of the outstanding shares as of the close of business on the record date are represented by stockholders present at the meeting or by proxy. At the close of business on the record date, there were 48,304,277 shares outstanding and entitled to vote. Therefore, in order for a quorum to exist, 24,152,139 shares must be represented by stockholders present at the meeting or by proxy.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other agent) or if you vote in person at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, a majority of the votes present at the meeting may adjourn the meeting to another date.

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 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 within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

What proxy materials are available on the Internet?

The proxy statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 are available at http://proxy2018.senomyx.com .

PROPOSAL 1

ELECTION OF DIRECTORS

Our Board of Directors currently consists of eight members. Michael E. Herman will be retiring and will not be standing for re-election at the annual meeting. As a result of Mr. Herman’s retirement, effective as of immediately following the annual meeting, the size of the Board will be reduced to seven members.

Each director elected at the annual meeting will serve until our 2019 Annual Meeting of Stockholders and until his or her successor is duly elected and qualified, or until his or her death, resignation or removal. Each of the nominees is currently a director of Senomyx. Directors are elected by a plurality of the votes present at the meeting or by proxy and entitled to vote at the meeting. The seven nominees receiving the most “For” votes (among votes properly cast in person or by proxy) will be elected. If no contrary indication is made, shares represented by executed proxies will be voted “For” the election of the seven nominees named below or, if any nominee becomes unavailable for election as a result of an unexpected occurrence, “For” the election of a substitute nominee designated by our Board of Directors. Each nominee has consented to be named in the proxy statement and to serve as a director if elected, and we have no reason to believe that any nominee will be unable to serve.

We encourage, but do not require, our Board members to attend our annual meeting of stockholders. All of our directors who were then serving on our Board attended our 2017 Annual Meeting of Stockholders.

It is important to note that the Corporate Governance and Nominating Committee seeks to assemble a Board of Directors that, as a whole, possesses the appropriate balance of professional and industry knowledge, financial expertise and high-level management experience necessary to oversee and direct our business. To that end, the Corporate Governance and Nominating Committee has evaluated nominees in the broader context of the Board’s overall composition, with the goal of maintaining a group of individuals where each person’s professional skills and experience will complement the skills and experience of the other members. In addition, the Corporate Governance and Nominating Committee also seeks to maintain a Board where each individual exhibits the high level of integrity and appropriate application of sound business judgment and other qualities that the committee views as important for the effective functioning of the Board.

Nominees

The following is biographical information as of March 1, 2018 for each nominee for director.

The brief biographies below include information regarding the experience, qualifications, attributes or skills of each nominee that led the Corporate Governance and Nominating Committee to believe that the nominee should continue to serve on the Board. However, each of the members of the Corporate Governance and Nominating Committee may have a variety of reasons why he believes a particular person is an appropriate nominee for the Board, and these views may differ from the views of the other members.

Independence of the Board of Directors and its Committees

As required under NASDAQ Stock Market listing standards, a majority of the members of a listed company’s Board of Directors must qualify as “independent,” as affirmatively determined by the board. Our Board of Directors consults with our legal counsel to ensure that the Board’s determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in applicable NASDAQ listing standards, as in effect from time to time. Consistent with these considerations, our Board has determined that all of our current directors are independent directors within the meaning of the applicable NASDAQ listing standards, except for Mr. Poyhonen, our President and Chief Executive Officer.

As required under applicable NASDAQ listing standards, our independent directors meet in regularly scheduled executive sessions at which only independent directors are present. All of the committees of our Board of Directors are comprised entirely of directors determined by the Board to be independent within the meaning of the applicable NASDAQ listing standards and free of any relationship that would impair his or her individual exercise of independent judgment with regard to Senomyx.

Board Leadership Structure

Our Board of Directors retains the flexibility to determine on a case-by-case basis whether the positions of Chief Executive Officer and Chairman of the Board should be combined or separate and whether an independent director should serve as Chairman. This flexibility permits the Board to organize its functions and conduct its business in a manner it deems most effective in then prevailing circumstances. Our Board of Directors is currently chaired by Mr. Snyder. Our Board believes that Mr. Snyder’s in-depth knowledge of our industry, the complex business and operations of Senomyx and his long tenure as a director make him well suited for the role of Chairman of the Board. Because of his extensive experience with the Company as our former Chief Executive Officer, Mr. Snyder possesses a detailed knowledge of our business and strategy and he is able to efficiently communicate and oversee the implementation of feedback from the Board to members of the Company’s management team. In addition, the Board believes that Mr. Snyder possesses the leadership skills and integrity that are appropriate for a Board Chairman, and he is able to effectively moderate the Board’s discussions and build a consensus among different points of view.

We have established a lead independent director policy that provides that if the Chairman of the Board is the Chief Executive Officer or is not an independent director, the independent directors shall appoint a lead independent director who shall be responsible for, among other things, chairing executive sessions in the absence of the Chairman of the Board, serving as a liaison between the Chairman of the Board and the independent directors and serving as an independent point of contact for stockholders wishing to communicate to the Board of Directors other than through the Chairman of the Board. As reinforcement of the importance of an independent Board, and as described above, the Board also routinely meets outside the presence of the Company’s management, including Mr. Poyhonen. Although our Chairman, Mr. Snyder, is independent within the meaning of the applicable NASDAQ listing standards, the Board appointed Dr. Gray to serve as the lead independent director to replace Dr. Short when he retired, in response to feedback received from our stockholders.

Board’s Role in Risk Oversight

Our management is responsible for the day-to-day management of the risks facing Senomyx, including macroeconomic, financial, strategic, operational, public reporting, legal, regulatory, political, compliance, and reputational risks. Management carries out this risk management responsibility through a coordinated effort among the various risk management functions within Senomyx.

Under our Bylaws, the Board has responsibility for overseeing the business and affairs of Senomyx. This general oversight responsibility includes oversight of risk management, which the Board carries out as a whole or through its committees. Among other things, the Board as a whole periodically reviews our enterprise risk management processes for identifying, ranking and assessing risks across the organization, as well as the output of that process. The Board also receives regular reports from members of the Company’s senior management on areas of material risk to Senomyx. In particular, our Board monitors and considers risk associated with our business strategy, scientific and technical risk, risk associated with existing and potential future collaborative research, development and license agreements, regulatory risk, inventory risk, liquidity risk, cybersecurity risk and other external risks inherent in our business. The Board does not have a standing risk management committee, but has delegated some specific functions relating to risk oversight to each of its standing committees.

Under its charter, the Audit Committee has the responsibility to consider and review with management and the Company’s independent registered public accountants the Company’s major financial risk exposures and the steps taken by management to monitor and control these exposures. In that regard, the Audit Committee oversees the engagement and performance of services by our independent registered public accountants, including routinely meeting with our independent registered public accountants outside the presence of management. The Audit Committee also periodically reviews the Company’s investment policy and establishes and oversees appropriate complaint procedures whereby employees or others may report suspected questionable accounting or auditing matters, or violations of the Company’s Code of Business Conduct and Ethics.

Under its charter, the Compensation Committee reviews and approves our compensation policies and programs and benefit plans affecting our executive officers, but also other Senomyx employees generally. In the course of those reviews, the Compensation Committee evaluates the potential of those policies, programs and benefits to influence employees to encourage excessive risk-taking. We do not believe our compensation policies, programs and benefits are reasonably likely to have a material adverse effect on the Company.

The Corporate Governance and Nominating Committee is involved in risk oversight associated with management succession by periodically reviewing and evaluating succession plans for our officers. The Corporate Governance and Nominating Committee also oversees the annual self-assessment process for our Board of Directors and each of its standing committees, which is intended to evaluate the effectiveness of Board and committee operations and proactively identify areas of potential improvement for the effective operation and performance of the Board and its committees.

While each committee is responsible for evaluating and managing certain risks, the chairs of the committees regularly report during regularly scheduled meetings of our full Board of Directors the significant risks facing Senomyx, as identified by management, and the measures undertaken by management for controlling and mitigating those risks.

Information Regarding the Board of Directors and its Committees

Our Board of Directors has three standing committees to facilitate and assist the Board in the execution of its responsibilities. These committees are currently the Audit Committee, the Compensation Committee and the Corporate Governance and Nominating Committee. Each standing committee operates pursuant to a written charter. Charters for each standing committee are available on our website at http://www.senomyx.com .

The table below shows the current membership for each of the standing Board committees.

From time to time the Board of Directors may also form special committees with responsibility for other matters as the need may arise. The following is a description of each standing committee and its functions.

Audit Committee

The charter of the Audit Committee grants the Audit Committee full access to all of our books, records, facilities and personnel, as well as 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. The Audit Committee met four times during the fiscal year ended December 31, 2017. The functions of the Audit Committee include, among other things:

•

reviewing and pre-approving the engagement of our independent registered public accounting firm to perform audit services and any permissible non-audit services;

•

reviewing our annual and quarterly financial statements and reports and discussing the statements and reports with our independent registered public accounting firm and management;

•

reviewing with our independent registered public accounting firm and management significant issues that arise regarding accounting principles and financial statement presentation, and matters concerning the scope, adequacy and effectiveness of our financial controls;

•

reviewing and approving or rejecting transactions between Senomyx and any related persons; and

•

establishing procedures for the receipt, retention and treatment of complaints received by us regarding financial controls, accounting or auditing matters.

Our Board of Directors has determined that Mr. Twomey qualifies as an “audit committee financial expert,” as defined in applicable SEC rules and is independent within the meaning of the applicable NASDAQ listing standards. The Board made a qualitative assessment of Mr. Twomey’s level of knowledge and experience based on a number of factors, including his formal education and prior work experience.

Report of the Audit Committee of the Board of Directors

The material in this report is not “soliciting material,” is not deemed “filed” with the SEC, and is not to be incorporated by reference into any filing of Senomyx under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended.

The purpose of the Audit Committee is to assist our Board of Directors in its general oversight of, among other things: our financial reporting and the integrity of our financial statements and related financial information; our internal control environment, systems and performance; the qualifications and independence of our independent registered public accounting firm; and the performance of our independent registered public accounting firm.

In carrying out these responsibilities, the Audit Committee, among other things: oversees the preparation of our annual and quarterly financial statements by management and reviews with management and our independent registered public accounting firm, prior to issuance, the information to be released and our Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q; retains our independent registered public accounting firm and oversees their work by reviewing the scope of audit services, approving all audit and non-audit services and fees to be paid, evaluating performance, and confirming independence; and oversees management’s implementation and maintenance of effective systems of internal and disclosure controls, including review of the processes with respect to the certifications by our Chief Executive Officer and Vice President, Finance that are required in periodic reports filed by Senomyx with the SEC.

The Audit Committee charter describes in greater detail the full responsibilities of the Audit Committee. Our Board of Directors has determined that all members of the Audit Committee are independent (as independence for audit committee members is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the NASDAQ listing standards).

Management is responsible for the preparation, presentation and integrity of the financial statements, accounting and financial reporting principles, and internal controls and procedures designed to ensure compliance with accounting standards, applicable laws and regulations. Our independent registered public accounting firm is responsible for annually performing an audit of financial statements and expressing an opinion as to their conformity with U.S. generally accepted accounting principles and the effectiveness of our internal control over financial reporting. In addition, our independent registered public accounting firm conducts quarterly reviews of our financial statements.

The Audit Committee reviews with our independent registered public accounting firm the scope of their services, the results of their audits and reviews, their evaluation of our internal controls, and the overall quality of our financial reporting. Our independent registered public accounting firm also periodically updates the Audit Committee about new accounting developments and their potential impact on our reporting. The Audit Committee meets regularly with our independent registered public accounting firm without management present. The Audit Committee also meets regularly with management without our independent registered public accounting firm present, and discusses management’s evaluation of our independent registered public accounting firm’s performance. The Audit Committee is not, however, employed by us, nor does it provide any expert assurance or professional certification regarding our financial statements. The Audit Committee relies, without independent verification, on the accuracy and integrity of the information provided, and representations made, by management and our independent registered public accounting firm.

With respect to 2017, the Audit Committee has reviewed and discussed the audited financial statements with management and our independent registered public accounting firm. The Audit Committee has reviewed and discussed with management its process for preparing its report on its assessment of the internal control over financial reporting, and at regular intervals received updates on the status of this process and actions taken by management to respond to issues and deficiencies identified. The Audit Committee discussed and reviewed with our independent registered public accounting firm their audit of internal control over financial reporting and their attestation report on the effectiveness of internal control over financial reporting, and the overall scope, plan and results of the independent registered public accounting firm’s examination of the financial statements.

In discharging its oversight responsibility as to the audit process, the Audit Committee obtained from our independent registered public accounting firm a formal written statement describing all relationships between our

independent registered public accounting firm and us that might bear on their independence consistent with applicable requirements of the Public Company Accounting Oversight Board (United States), or PCAOB. The Audit Committee discussed with our independent registered public accounting firm any relationships that may impact their objectivity and independence, including fees paid relating to the audit and any non-audit services performed, and satisfied itself as to that firm’s independence. The Audit Committee also discussed and reviewed with our independent registered public accounting firm all communications required by Auditing Standard No. 16, Communications with Audit Committees , as amended and as adopted by the PCAOB.

Based upon the Audit Committee’s discussion with management and our independent registered public accounting firm and the Audit Committee’s review of the representation of management and the report of the independent registered public accounting firm to the Audit Committee, subject to the limitations on the role and responsibility of the Audit Committee referred to in the written charter of the Audit Committee, the Audit Committee recommended to our Board of Directors that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2017 for filing with the SEC. The Audit Committee also approved the selection, subject to stockholder ratification, of our independent registered public accounting firm and the Board concurred in such authorization.

Compensation Committee

The Compensation Committee met six times during the fiscal year ended December 31, 2017. The functions of the Compensation Committee include, among other things:

•

determining the compensation and other terms of employment of our named executive officers and reviewing corporate performance goals and objectives relevant to such compensation;

•

recommending to our Board of Directors the type and amount of compensation to be paid or awarded to board members;

•

evaluating and recommending to our Board of Directors the equity incentive plans, compensation plans and similar programs for our employees, as well as modification or termination of existing plans and programs;

•

establishing policies with respect to equity compensation arrangements;

•

reviewing and approving the terms of any employment agreements, severance arrangements, change-in-control protections and any other compensatory arrangements for our named executive officers; and

•

reviewing with management our Compensation Discussion and Analysis and working with our management to prepare the relevant disclosures in proxy statements and other filings.

Typically, the Compensation Committee meets at least quarterly and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with the Chief Executive Officer and human resources and other representatives of senior management as necessary. The Compensation Committee meets regularly in executive session. However, various members of management and other employees, as well as outside advisors or consultants, may be invited by the Compensation Committee to make presentations, provide financial or other background information or advice or otherwise participate in Compensation Committee meetings. For instance, the Compensation Committee routinely monitors legislative and regulatory developments that may impact our compensation programs, and where appropriate solicits input from our internal and external legal counsel with respect to actual and proposed changes in applicable laws and regulations. The Chief Executive Officer does not participate and is not present during deliberations or determinations of the Compensation Committee regarding his compensation. The charter of the Compensation Committee grants the Compensation Committee full access to all of our books, records, facilities and personnel, as well as 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 Compensation Committee considers necessary or appropriate in the performance of its duties. In particular, the Compensation Committee has the sole authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. The Compensation Committee annually evaluates the qualifications, performance and independence of its advisors. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the compensation committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and NASDAQ, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

During the past fiscal year, the Compensation Committee approved the engagement of Marsh and McLennan Agency, or MMA, formerly known as MMA LLC, as our compensation consultants. The Compensation Committee requested that MMA evaluate the compensation for our Board of Directors and executive team and make recommendations as necessary to achieve our compensation objectives.

As part of its engagement, MMA was requested by the Compensation Committee to recommend a group of peer companies and to generate comparative compensation data from that peer group. At the request of the Compensation Committee, MMA, as necessary to perform their duties, also conducts individual interviews with members of senior management and human resources to learn more about Senomyx’s business operations and strategy, key performance metrics and strategic goals, as well as the labor markets in which Senomyx competes. MMA, with management’s assistance, ultimately developed recommendations that were presented to the Compensation Committee for its consideration.

Under its charter, the Compensation Committee may form, and delegate authority to, subcommittees, as appropriate. The Compensation Committee has formed a Non-Officer Stock Option Committee, or NOSOC, currently composed of Mr. Poyhonen, to which it delegated authority to grant, without any further action required by the Compensation Committee, stock options to our employees who are not officers. From time to time the NOSOC may also be authorized to grant, without any further action required by the Compensation Committee, stock options to external advisors or consultants. The purpose of delegating authority to the NOSOC is to enhance the flexibility of option administration and to facilitate the timely grant of options to non-management employees, particularly new employees, and key external advisors and consultants within specified limits approved by the Compensation Committee. The size of grants made by the NOSOC must be within limits pre-approved by the Compensation Committee. During the fiscal year ended December 31, 2017, the NOSOC exercised its authority to grant options to purchase an aggregate of 367,430 shares of Common Stock to non-officer employees.

Historically, the Compensation Committee has made adjustments to annual compensation, determined bonus and equity awards and established new performance objectives at one or more meetings held during the first quarter of the year. However, the Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the effectiveness of our compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Compensation Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee, which determines any adjustments to his compensation as well as awards to be granted. For all executives and directors, as part of its deliberations, the Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, company stock performance data, analyses of historical executive compensation levels and current company-wide compensation levels, and recommendations of the Compensation Committee’s compensation consultant, including analyses of executive and director compensation paid at other companies identified by the consultant.

The specific determinations of the Compensation Committee with respect to executive compensation are described in greater detail in the Compensation Discussion and Analysis section of this proxy statement.

Compensation Committee Interlocks and Insider Participation

As indicated above, the Compensation Committee currently consists of Dr. Gray and Messrs. Stebbins and Herman (who is retiring and will not be standing for re-election at the annual meeting). No member of the Compensation Committee has ever been an officer or employee of Senomyx. None of our named executive officers currently serves, or has served during the last completed fiscal year, on the Compensation Committee or Board of Directors of any other entity that has one or more named executive officers that is serving as a member of our Board of Directors or Compensation Committee.

Corporate Governance and Nominating Committee

The Corporate Governance and Nominating Committee has responsibility for, among other things, reviewing annually with the Board the size and composition of the Board with the objective of achieving the appropriate balance of knowledge, experience, skills, expertise and diversity required for the Board as a whole. The charter of the Corporate Governance and Nominating Committee grants the Corporate Governance and Nominating Committee full access to all of our books, records, facilities and personnel, as well as 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 Corporate Governance and Nominating Committee considers necessary or appropriate in the performance of its duties. The Corporate Governance and Nominating Committee met five times during the fiscal year ended December 31, 2017. The functions of the Corporate Governance and Nominating Committee include, among other things:

•

developing and maintaining a current list of the functional needs and qualifications of members of our Board of Directors;

•

overseeing the self-evaluation process on the Board and applicable committees of the Board and determining whether continued service on our Board is appropriate;

•

interviewing, evaluating, nominating and recommending individuals for membership on our Board of Directors;

•

evaluating nominations by stockholders of candidates for election to our Board;

•

overseeing the self-assessment process for our Board and the applicable committees of the Board;

•

developing, reviewing and amending a set of corporate governance policies and principles;

•

considering questions of possible conflicts of interest of directors as such questions arise; and

•

recommending to our Board of Directors the establishment of such special committees as may be desirable or necessary from time to time in order to address ethical, legal, business or other matters that may arise.

In evaluating candidates for the Board, the Governance Committee reviews each candidate’s biographical information and credentials, and assesses each candidate’s independence, skills, experience and expertise based on a variety of factors. Members of the Board should have the highest professional and personal ethics, integrity and values consistent with Senomyx’s values. The Corporate Governance and Nominating Committee will consider whether the candidate has had a successful career that demonstrates the ability to make the kind of important and sensitive judgments that the Board is called upon to make, and whether the candidate’s skills are complementary to the existing Board members’ skills. Board members must take into account and balance the legitimate interests and concerns of all of our stockholders and other stakeholders, and each must be able to devote sufficient time and energy to the performance of his or her duties as a director. However, the Corporate Governance and Nominating Committee retains the right to modify its approach to evaluating the qualifications of director nominees from time to time.

Candidates for director nominees are reviewed in the context of the current composition of our Board of Directors, our operating requirements and the long-term interests of our stockholders. In conducting this assessment, the Corporate Governance and Nominating Committee considers diversity, age, skills, and such other factors as it deems appropriate given the current needs of the Board and Senomyx, to maintain a balance of knowledge, experience and capability. Although the Board does not maintain a formal policy regarding diversity, the Corporate Governance and Nominating Committee considers diversity to include diversity of backgrounds, cultures, education, experience, skills, thought, perspectives, personal qualities and attributes. Our Corporate Governance and Nominating Committee and Board believe that a diverse representation on the Board fosters a robust, comprehensive, and balanced deliberative decision-making process that is essential to the continued effective functioning of the Board and our continued success.

In the case of incumbent directors whose terms of office are set to expire, the Corporate Governance and Nominating Committee reviews such directors’ overall service to us during their term, including the number of meetings attended, level of participation, quality of performance, and any other relevant considerations. In the case of new director candidates, the Corporate Governance and Nominating Committee considers all qualified candidates who may be identified by any one of the following sources: current or former Board members, a professional search firm, Company executives or stockholders. The Corporate Governance and Nominating Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Corporate Governance and Nominating Committee to become nominees for election to the Board at an annual meeting of stockholders must do so by complying with procedural requirements set forth in our Bylaws, including delivering at least 120 days prior to the anniversary date of the mailing of the proxy statement for our last annual meeting of stockholders a written recommendation to the Corporate Governance and Nominating Committee at the following address: Senomyx, Inc., 4767 Nexus Centre Drive, San Diego, California 92121. To date, the Corporate Governance and Nominating Committee has not received a director nominee from a stockholder or stockholders holding more than 5% of our voting stock.

Meetings of the Board of Directors and Board and Committee Member Attendance

Our Board of Directors met fourteen times during the last fiscal year. Each Board member attended at least 85% of all of the 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, respectively.

Stockholder Communications with the Board of Directors

Our Board of Directors has adopted a formal process by which our stockholders may communicate with our Board of Directors or individual directors. Stockholders who wish to communicate with our Board of Directors may do so by sending written communications addressed to our Corporate Secretary at Senomyx, Inc., 4767 Nexus Centre Drive, San Diego, California 92121. Each communication must set forth: the name and address of the Senomyx stockholder on whose behalf the communication is sent; and the number of shares of our common stock that are owned beneficially by such stockholder as of the date of the communication. All communications will be compiled by our Corporate Secretary and submitted to our Board of Directors, the appropriate committee thereof or an individual director, as applicable, on a periodic basis.

Hedging Policy

Our insider trading policy prohibits our directors, officers and other employees from engaging in any hedging transactions with respect to our common stock, including trading in any derivative security relating to Senomyx stock.

CODE OF BUSINESS CONDUCT AND ETHICS

We have adopted a Code of Business Conduct and Ethics that applies to all of our officers, directors and employees. The Code of Business Conduct and Ethics is available on our website at http://www.senomyx.com . If we make any substantive amendments to the Code of Business Conduct and Ethics or grant any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website, as well as via any other means then required by NASDAQ listing standards or applicable law.

ACCOUNTING AND AUDITING MATTERS OPEN DOOR POLICY

We have adopted an Open Door Policy for Reporting Complaints Regarding Accounting, Auditing and Other Matters to facilitate the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters, as well as the confidential, anonymous submission by our employees of concerns regarding these matters. The Open Door Policy is available on our website at http://www.senomyx.com .

PROPOSAL 2

APPROVAL OF AMENDMENT TO THE SENOMYX, INC.

2004 EMPLOYEE STOCK PURCHASE PLAN

Our Board of Directors approved the 2004 Employee Stock Purchase Plan, or 2004 ESPP, at its April 30, 2004, meeting and the first amendment to the 2004 ESPP, or First Amendment, on March 28, 2013. Our stockholders approved the 2004 ESPP on June 7, 2004 and the First Amendment on April 24, 2013. The 2004 ESPP is intended to encourage employee participation in the ownership of the Company by offering employees the opportunity to purchase our common stock through accumulated payroll deductions. We also believe that offering employees the opportunity to purchase our common stock through the 2004 ESPP is an effective and cost efficient method to recruit, motivate and retain the services of our employees.

As of March 31, 2018 there were 841,640 shares of our common stock available for future issuance under the terms of the 2004 ESPP and we anticipate that all of these shares will be purchased at the February 2019 purchase date under the 2004 ESPP.

In order to continue to offer employees the opportunity to purchase our common stock under the terms of the 2004 ESPP, on March 30, 2018 our Board of Directors approved a second amendment to the 2004 ESPP, or Second Amendment, subject to approval from stockholders at our 2018 Annual Meeting of Stockholders. The Second Amendment increases the shares of our common stock authorized and available for future issuance under the 2004 ESPP by 2,000,000 shares as of our 2018 Annual Meeting of Stockholders. If this Proposal 2 is approved by our stockholders, the additional 2,000,000 shares that will be made available under the 2004 ESPP for grants beginning with the first offering period that commences following our annual meeting. We anticipate that the additional 2,000,000 shares should be sufficient to satisfy subscriptions under future offerings for approximately two to three years.

If this Proposal 2 is approved by our stockholders, the Second Amendment will become effective upon the date of the annual meeting. In the event that our stockholders do not approve this Proposal 2, the Second Amendment will not become effective and the 2004 ESPP, as amended by the First Amendment, will continue in its current form until all shares available have been issued and thereafter the 2004 ESPP will terminate.

Because we believe that the 2004 ESPP aligns our employees’ interests with those of our stockholders, and is effective to motivate and retain the services of our employees and to recruit new employees, if our stockholders do not approve this Proposal 2 the Compensation Committee and Board of Directors may consider the implementation of alternative means to achieve the desired alignment between the interests of our employees and our stockholders and to restore the full range of incentive and retention values of the 2004 ESPP. Consequently, we believe that it is in the best interests of the Company that the stockholders approve this Second Amendment to the 2004 ESPP.

Participation in the 2004 ESPP

Participation in the 2004 ESPP is voluntary and is dependent on each eligible employee’s election to participate and his or her determination as to the level of payroll deductions. Accordingly, future purchases under the 2004 ESPP are not determinable. Non-employee directors are not eligible to participate in the 2004 ESPP.

Description of the 2004 ESPP

The material features of the 2004 ESPP are outlined below. This summary is qualified in its entirety by reference to the complete text of the 2004 ESPP, as amended by the Second Amendment. Stockholders are urged to read the actual text of the 2004 ESPP, as amended by the Second Amendment, in its entirety, which is appended as Appendix A to the copy of this Proxy Statement filed with the SEC, which may be accessed from the SEC’s website at www.sec.gov and which we made available online at http://www. proxy2018.senomyx.com.

General.

The 2004 ESPP provides a means by which employees may purchase our common stock through payroll deductions, and is intended to qualify as an employee stock purchase plan within the meaning of Section 423 of the Internal Revenue Code.

Share Reserve.

Following approval of the Second Amendment to the 2004 ESPP at our 2018 Annual Meeting of Stockholders, an aggregate of 2,841,640 shares of our common stock will be reserved for issuance under the 2004 ESPP which will include 2,000,000 shares of our common stock reserved for future grants under the 2004 ESPP beginning with the first offering period that commences following our 2018 Annual Meeting of Stockholders. These amounts are fixed so that stockholder approval is required to issue any additional shares.

Administration.

The 2004 ESPP will be administered by our Board of Directors, who may in turn delegate authority to administer the 2004 ESPP to a committee.

Offering.

The 2004 ESPP is implemented by offerings of rights to eligible employees. Under the 2004 ESPP, we may specify offerings with a duration of not more than 27 months, and may specify shorter purchase periods within each offering.

Unless otherwise determined by the Board of Directors or its authorized committee, common stock is purchased for accounts of employees participating in the 2004 ESPP at a price per share equal to the lower of (1) 85% of the fair market value of a share of our common stock on the date of commencement of participation in the offering or (2) 85% of the fair market value of a share of our common stock on the date of purchase. Generally, all regular employees, including executive officers, who work more than 20 hours per week and are customarily employed by us for more than five months per calendar year may participate in the 2004 ESPP and may authorize payroll deductions of up to 15% of their earnings for the purchase of common stock under the 2004 ESPP.

Limitations.

Eligible employees may be granted rights only if the rights, together with any other rights granted under employee stock purchase plans, do not permit the employee’s rights to purchase our stock to accrue at a rate which exceeds $25,000 of the fair market value of the stock for each calendar year in which such rights are outstanding. In addition, no employee will be eligible for the grant of any rights under the 2004 ESPP if immediately after such rights are granted, such employee has voting power over 5% or more of our outstanding capital stock.

Corporate Transactions.

In the event of certain corporate transactions, all outstanding purchase rights under the 2004 ESPP may be assumed or substituted for by any surviving entity. If the surviving entity elects not to assume or substitute for such purchase rights, then the purchase rights will be exercised prior to the corporate transaction and the ongoing offerings and purchase rights will terminate immediately following such exercise.

Plan Amendments and Termination.

Our Board of Directors has the authority to amend or terminate the 2004 ESPP. To the extent necessary to comply with applicable provisions of federal securities laws, state corporate and securities laws, the Internal Revenue Code, the rules of any applicable stock exchange or national market system, and the rules of any non-United States jurisdiction applicable to awards granted to residents therein, we shall obtain stockholder approval of any such amendment to the 2004 ESPP in such a manner and to such a degree as required. The 2004 ESPP will terminate at the time that all of the shares of our common stock reserved for issuance under the 2004 ESPP have been issued under the terms of the 2004 ESPP, unless our Board of Directors terminates it earlier.

Required Vote and Board of Directors Recommendation

Approval of this Proposal 2 requires the affirmative vote of a majority of the shares present or represented by proxy and entitled to vote on this matter at the annual meeting. Abstentions will be counted toward the tabulation of votes cast on the proposal and will have the same effect as “Against” votes. Broker non-votes are counted towards a quorum, but will have no effect on the outcome of the vote.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE APPROVAL OF THE AMENDMENT TO THE 2004 EMPLOYEE STOCK PURCHASE PLAN.

PROPOSAL 3

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of our Board of Directors has engaged Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2018 and is seeking ratification of such selection by our stockholders at the annual meeting. Ernst & Young LLP has audited our financial statements since 2000. Representatives of Ernst & Young LLP are expected to be present at the annual meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions. Neither our Bylaws nor other governing documents or law requires stockholder ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm. However, the Audit Committee is submitting the selection of Ernst & Young LLP to our stockholders for ratification as a matter of good corporate practice. If our stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain Ernst & Young LLP. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of one or more different independent registered public accounting firms at any time during the year if they determine that such a change would be in the best interests of Senomyx and our stockholders.

To be approved, the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm must receive a “For” vote from the majority of shares present and entitled to vote on this matter either in person or by proxy. Abstentions will be counted toward the tabulation of votes cast on this proposal and will have the same effect as “against” votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

Pre-Approval Policies and Procedures

The Audit Committee has established a policy that all audit and permissible non-audit services provided by our independent registered public accounting firm will be pre-approved by the Audit Committee. These services may include audit services, audit-related services, tax services and other services. The Audit Committee considers whether the provision of each non-audit service is compatible with maintaining the independence of our auditors. Pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. Our independent registered public accounting firm and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, and the fees for the services performed to date.

PROPOSAL 4

ADVISORY VOTE ON EXECUTIVE COMPENSATION

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and Section 14A of the Exchange Act, our stockholders are entitled to vote to approve, on an advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with SEC rules. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement.

The compensation of our named executive officers subject to the vote is disclosed in the Compensation Discussion and Analysis, the compensation tables, and the related narrative disclosure contained in this proxy statement. As discussed in those disclosures, the compensation of the named executive officers is designed to enable us to attract and retain talented and experienced executives to lead Senomyx successfully in a competitive environment. Not only do we believe the compensation program for the named executive officers is consistent with a pay-for-performance philosophy, we also believe that the compensation program is strongly aligned with the long-term interests of our stockholders. Overall, we believe our compensation program for our named executive officers has been instrumental in our achievement of research and development, commercial and financial goals over the past several years.

Accordingly, the Board is asking stockholders to indicate their support for the compensation of our named executive officers as described in this proxy statement by casting a non-binding advisory vote “FOR” the following resolution:

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

Because the vote is advisory, it is not binding on the Board of Directors or Senomyx. Nevertheless, the views expressed by stockholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.

Advisory approval of this proposal requires the vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote on this matter at the annual meeting. Abstentions will be counted toward the tabulation of votes cast on the proposal and will have the same effect as “Against” votes. Broker non-votes will be counted towards a quorum, but will not be counted for any purpose in determining whether this matter has been approved.

A VOTE FOR PROPOSAL 4

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table provides information regarding the beneficial ownership of our common stock as of March 1, 2018 by: (i) each of our directors, (ii) each of our named executive officers, (iii) all of our directors and executive officers as a group and (iv) each person, or group of affiliated persons, known by us to beneficially own more than five percent of our common stock. The table is based upon information supplied by our officers, directors and principal stockholders and a review of Schedules 13D and 13G, if any, filed with the SEC. Unless otherwise indicated in the footnotes to the table and subject to community property laws where applicable, we believe that each of the stockholders named in the table has sole voting and investment power with respect to the shares indicated as beneficially owned.

Applicable percentages are based on 48,304,277 shares outstanding on March 1, 2018, adjusted as required by rules promulgated by the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options or warrants that are either immediately exercisable or exercisable on April 30, 2018, which is 60 days after March 1, 2018. These shares are deemed to be outstanding and beneficially owned by the person holding those options or warrants for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Certain of the options in this table are exercisable at any time but, if exercised, are subject to a lapsing right of repurchase until the options are fully vested.

Officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations that no other reports were required, during the fiscal year ended December 31, 2017, all Section 16(a) filing requirements applicable to our officers, directors and greater than ten percent beneficial owners were complied with.

DIRECTOR COMPENSATION FOR FISCAL 2017

The following table sets forth in summary form information concerning the compensation that we paid during the fiscal year ended December 31, 2017 to each of our non-employee directors. Mr. Poyhonen, our President and CEO, is not included in this table as he is an employee of Senomyx and thus receives no compensation for his service as a director. Mr. Edrmann is not included in this table as he was not a director during the fiscal year ended December 31, 2017. The compensation paid to or earned by Mr. Poyhonen as an officer of Senomyx is shown in the 2017 Summary Compensation Table.


Name	Fees Earned or Paid in Cash ($)		Option Awards (1)(2) ($)		Total ($)
Stephen A. Block, Esq.		60,000		12,256		72,256
Mary Ann Gray, Ph.D.		69,728		12,256		81,984
Michael E. Herman		47,500		12,256		59,756
Jay Short (3)		26,092		—		26,092
Kent Snyder		70,000		12,256		82,256
Daniel E. Stebbins		50,701		12,256		62,957
Christopher J. Twomey		67,000		12,256		79,256

(1)

Amounts listed in this column represent the full grant date fair value calculated in accordance with FASB ASC Topic 718 for awards granted during the fiscal year. Assumptions made for the purpose of computing these amounts are discussed in our Annual Report on Form 10-K for the year ended December 31, 2017 in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 1 to Financial Statements under the heading “Stock-Based Compensation.” The actual amount ultimately realized by a director will likely vary based on a number of factors.

(2)	The aggregate number of shares subject to option awards outstanding as of December 31, 2017 was as follows:


Name	Shares Subject to Option Awards
Stephen A. Block, Esq.		115,639
Mary Ann Gray, Ph.D.		148,750
Michael E. Herman		181,300
Kent Snyder*		1,941,000
Daniel E. Stebbins		70,000
Christopher J. Twomey		181,300

*	Mr. Snyder was awarded most of these options during his tenure as our President and CEO.

(3)	Dr. Short’s service as a non-employee director ended effective May 10, 2017 and, as a result, he received neither a stock option award for 2017 nor a cash retainer for the third and fourth fiscal quarters of 2017.

Effective January 1, 2015, we provided each of our non-employee directors with cash compensation in the form of an annual retainer of $40,000, except for the Chairman of the Board and lead independent director, who received an annual retainer of $70,000 and $60,000, respectively. In addition, during 2017 we compensated our directors for their service on Board committees with the payment of the following additional annual retainers:


Committee	Chairperson		Member
Audit Committee	$	22,000	$	10,000
Compensation Committee	$	15,000	$	7,500
Corporate Governance and Nominating Committee	$	10,000	$	5,000

All annual retainers are paid in equal quarterly installments in advance. No increases have been recommended to the cash compensation structure for our non-employee directors for the current 2018 calendar year. The cash compensation will be the same as the cash compensation structure described above for 2017.

As part of our current compensation structure for non-employee directors, we do not pay any additional per meeting attendance fees. However, we do reimburse our non-employee directors for their reasonable expenses incurred in attending meetings of our Board of Directors and committees of the Board. From time to time the Board of Directors may also form special committees with responsibility for matters as the need may arise and may implement additional compensation arrangements for a non-employee’s service on a special committee.

Each of our non-employee directors also receives stock option grants under our non-employee directors’ nonstatutory stock option program, or the directors’ program, which is a part of and administered under the Senomyx, Inc. 2013 Equity Incentive Plan, or the 2013 Equity Plan, which became effective on January 1, 2014. Prior to that date, the directors’ program was administered under the Senomyx, Inc. 2004 Equity Incentive Plan, or the 2004 Equity Plan. Only our non-employee directors or affiliates of such directors (as defined in the Internal Revenue Code) are eligible to receive stock awards for their service on the Board of Directors. Options granted to our non-employee directors or any affiliates of such directors are not intended to qualify as incentive stock options under the Internal Revenue Code.

Option grants under the directors’ program are non-discretionary. Each person who became a non-employee director in 2017 would have automatically received an initial option grant to purchase 30,000 shares of our common stock upon his or her election or appointment. These grants are referred to as initial grants.

Each person who is a non-employee director on the date of each annual meeting of our stockholders where he or she is re-elected to our Board of Directors is automatically granted, on the date of such re-election, an option to purchase shares of our common stock. These grants are referred to as annual grants. The size of any annual grant made to a non-employee director who has served for less than 12 months at the time of the annual meeting is reduced pro-rata for each full month prior to the date of grant for which such person did not serve as a non-employee director. In 2017, non-employee directors, including a non-employee Chairman of the Board, received annual grants to purchase 20,000 shares of our common stock.

The equity compensation structure for our non-employee directors for the current 2018 calendar year will be the same as the equity compensation structure described above for 2017.

The exercise price of the options granted under the directors’ program is equal to 100% of the fair market value of the common stock on the date of grant. Initial grants vest in equal monthly installments over a three-year period following the date of grant. Annual grants vest in equal monthly installments over a one year period following the option grant date. In the event of a change in our control, all outstanding options under the directors’ program become vested in full and fully exercisable. In general, the term of stock options granted under the directors’ program may not exceed ten years.

Under both the 2004 Equity Plan and the 2013 Equity Plan, unless the terms of an optionee’s stock option agreement provide for earlier or later termination, if an optionee’s service relationship with us, or any affiliate of ours, ceases due to disability or death, the optionee, or his or her beneficiary, may exercise any vested options up to 12 months, or 18 months in the event of death, after the date such service relationship ends. If an optionee’s service relationship with us, or any affiliate of ours, ceases without cause for any reason other than disability or death, the optionee may exercise any vested options up to twelve months from cessation of service, unless the terms of the stock option agreement provide for earlier or later termination. If an optionee’s relationship with us, or any affiliate of ours, ceases with cause, the option will terminate at the time the optionee’s relationship with us ceases. In no event may an option be exercised after its expiration date.

Acceptable consideration for the purchase of common stock issued under both the 2004 Equity Plan and the 2013 Equity Plan will be determined by our Board of Directors and may include cash, common stock previously owned by the optionee, the net exercise of the option, consideration received in a “cashless” broker-assisted sale and other legal consideration approved by our Board of Directors. Generally, an optionee may not transfer a stock option other than by will or the laws of descent and distribution unless the optionee holds a nonstatutory stock option that provides otherwise. However, an optionee may designate a beneficiary who may exercise the option following the optionee’s death.

In addition, under both the 2004 Equity Plan and the 2013 Equity Plan, the Board has the power to accelerate the time at which an option may first be exercised or the time during which an option will vest and the Board may amend the terms of any option, including, but not limited to, amendments to provide terms more favorable than previously provided in the agreement evidencing an option. Under the 2013 Equity Plan, the Board also has the power to make additional stock awards to directors outside of the non-discretionary directors’ program.

John Poyhonen		President, Chief Executive Officer
Dave Humphrey		Vice President, Finance
Catherine C. Lee		Senior Vice President, General Counsel and Corporate Secretary
Sharon Wicker		Senior Vice President and Chief Commercial Development Officer

(1)	Mr. Rogers resigned from his position of SVP and Chief Financial Officer, effective as of July 28, 2017.

Executive Summary

Our compensation program for executive officers is designed to align the financial interests of our executive officers with those of our stockholders. A key to creating this alignment is placing a substantial amount of executive compensation at risk based on both the short and long-term performance of the Company, while discouraging any short-sighted risk-taking behavior. Additionally, our success depends, among other things, on attracting and retaining executive officers with experience and skills in a number of different areas as we continue to discover, develop and commercialize products, pursue and establish key commercial relationships, and maintain a reliable supply chain and manufacturing alliances.

When determining the compensation for our executive officers, the Compensation Committee benchmarks the various components of compensation to executive compensation paid by public companies in our defined peer group, compensation data from industry surveys, historical review of all executive officer compensation and recommendations from our CEO (excluding his own compensation). The Compensation Committee also considers the current financial position of the Company, the strategic goals and the performance of each of our executive officers.

The Compensation Committee continued to strengthen the foundation of our executive compensation program, taking the following actions for fiscal 2017:

•

Continued to benchmark total direct compensation of our executive officers at the 50th percentile within the peer group. In 2017, the actual total direct compensation for all of our named executive officers was at or below the 50 ^th percentile within our peer group.

•

Continued the focus on pay for performance, basing the 2017 Executive Bonus Plan, or 2017 Bonus Plan, on the Company’s achievement of a combination of pre-determined commercialization, financial, and discovery and development goals. Our corporate goals are collectively designed to be stretch goals intended to be very challenging but attainable. In addition, a minimum corporate goal achievement of greater than or equal to 50% is required for an executive officer to earn a performance based cash bonus. Furthermore, minimum achievement thresholds were included in the 2017 Bonus Plan related to the commercialization and financial performance metrics of the corporate goals as further described below:

•

With respect to the commercial and development revenue performance metric, a minimum achievement threshold of 85% was required in order to attain partial goal achievement of such goal.

•

With respect to the net operating results performance metric, a minimum achievement threshold of 85% was required in order to attain partial goal achievement of such goal.

•

With respect to the cash balance performance metric, a minimum achievement threshold of 75% was required in order to attain goal achievement of such goal.

•

Continued to not provide tax reimbursements, supplemental retirement benefits or other perquisites to the executive officers that are not available to employees generally.

•

Continued use of an independent compensation consultant for independent advice and market data.

Our Compensation Philosophy

The ability to compete effectively in the market within which we operate depends to a large extent on our success in identifying, recruiting, developing and retaining management talent. We also need to remain focused on creating sustainable long-term growth and stockholder value. To this end, the design of our executive compensation program and the decisions made by the Compensation Committee are guided by the following principles:

•

Pay for performance . We believe that our program should motivate high performance among our executive officers and our compensation program places significant emphasis on pay-for-performance, which we measure primarily based on the achievement of the Company’s corporate goals. Our executive compensation can be highly variable, and is heavily influenced by our achievement of corporate goals. The cash bonus awards paid pursuant to our performance-based bonus plans are determined entirely on our achievement of specified corporate goals for the applicable year. Because a meaningful portion of the compensation program for the executive officers is tied to the Company’s achievement of its corporate goals, which are then used to establish more specific individual goals at different levels of management within the organization, we believe our compensation arrangements also had the effect of motivating all of the Company’s employees to achieve key corporate goals during the past several years. We believe this philosophy encourages the achievement of both near-term and long-term objectives in a way that is aligned with the interests of our stockholders.

With respect to equity based compensation, the amount of an annual stock option award is primarily determined by our overall performance against specified corporate goals during the prior year. In addition, the executive officer’s individual performance during the prior year and his or her level of responsibility within the organization are also taken into consideration. The Compensation Committee utilizes stock options to help ensure that executive officers will realize value only if our stockholders realize value on their shares. Stock options also foster retention of key executives since the awards generally vest over the four-year period following the performance period and we believe this is also consistent with a pay-for-performance philosophy.

•

Competitive compensation . We aim to provide compensation opportunities that is competitive with that being offered to individuals holding comparable positions at other public companies with which we compete for business and talent so that we can attract, motivate and retain qualified individuals. We target our compensation at the 50th percentile within our peer group. However, in 2017, the actual total direct compensation for all of our named executive officers was at or below the 50 ^th percentile within our peer group.

•

Focus on total direct compensation . We seek to offer a total executive compensation package that best supports our leadership talent and business strategies with a combination of base salary, performance-based bonus, and long-term equity awards:


Element	Form	Purpose
Base Salary	Cash (Fixed)	Provides a competitive level of pay that reflects the executive’s experience, role and responsibilities
Annual Performance-Based Bonus	Cash (Variable)	Rewards achievement of predetermined corporate commercialization, financial, and discovery and development goals for the most recently completed fiscal year
Long-Term Incentives	Equity (Variable)	Provides meaningful incentives for management to execute on longer-term financial and strategic growth goals that drive stockholder value creation and supports the Company’s retention strategy

We believe this combination of cash and equity, subject to strategic allocation among such components, is largely consistent with the forms of compensation provided by other companies with which we compete for executive talent. We also believe that this combination provides appropriate incentive levels to retain our executives, reward them for performance in the short term and contribute to the creation of value in the Company over the long term. We view the different components of our executive compensation as distinct, each serving a particular function in furthering our compensation philosophy and objectives, and, together, providing a holistic approach to achieving our philosophy and objectives.

Advisory Vote on Executive Compensation

At our 2017 Annual Meeting of Stockholders, we held a stockholder advisory vote on the compensation of our named executive officers and it received the support of 81% of the total votes cast. At that same meeting, we also held an advisory vote on the frequency of future advisory votes on executive compensation, and our stockholders supported our recommendation to hold future advisory votes every year.

The Compensation Committee has considered the results of the vote in 2017 and, in part because our compensation program is comprised of similar components and metrics as previously presented to stockholders, has concluded that the executive compensation program continues to provide a competitive pay-for-performance package that effectively motivates our executive officers and encourages long-term retention. Accordingly, the Compensation Committee made no significant changes to our executive compensation programs during the year. The Compensation Committee will continue to consider stockholder views about our core compensation principles and objectives when determining our executive compensation program in the future.

CEO Pay Ratio

We believe our executive compensation program must be internally consistent and equitable to motivate our employees to create stockholder value. We are committed to internal pay equity, and the Compensation Committee monitors the relationship between the compensation of our executive officers and the compensation of our non-executive employees. We believe we achieve this goal by providing all employees access to, or the ability to participate in, our compensation programs. The compensation for our CEO in 2017 was approximately 10 times the median pay of our full-time employees.

We identified the median employee by examining the 2017 total cash compensation for all individuals, excluding our CEO, who were employed by us on December 29, 2017, the last day of our payroll year (whether employed on a full-time, part-time, or seasonal basis). For such employees, we did not make any assumptions,

adjustments, or estimates with respect to total cash compensation, and we did not annualize the compensation for any full-time employees that were not employed by us for all of 2017. After identifying the median employee, we calculated annual total compensation for such employee using the same methodology we use for our named executive officers as set forth in the 2017 Summary Compensation Table later in this proxy statement. As illustrated below, our CEO to median employee pay ratio is 10 to 1:


	President and CEO		Median Employee
Base Salary	$	533,000	$	97,363
Non-Equity Incentive Plan Compensation		311,805		12,049
Option Awards		289,481		1,666
All Other Compensation		4,050		1,600
TOTAL		1,138,364		112,678

The Role of Our Compensation Committee

The Compensation Committee is comprised of independent directors within the meaning of the applicable SEC and NASDAQ Stock Market rules. The Compensation Committee responsibilities and duties are outlined in detail under the heading “Information Regarding the Board of Directors and its Committees – Compensation Committee” and the Compensation Committee charter, which is available on our website at www.senomyx.com . Pursuant to its charter, the Compensation Committee’s responsibilities include determining the compensation for our executive officers and evaluating the Chief Executive Officer’s performance in light of such applicable pre-determined goals and objectives and reviewing and recommending the Chief Executive Officer’s compensation to the Board for approval.

Use of Peer Group Data

Our Compensation Committee compares our executive compensation program to a group of companies that are comparable based on a number of factors including size and industry and companies with which we compete for talent, or a peer group. The overall purpose of this peer group is to provide a market frame of reference for evaluating our compensation arrangements (current or proposed), understanding compensation trends among comparable companies, and reviewing other compensation-related topics that may arise during the course of the year.

During 2017, the Compensation Committee approved the engagement of MMA to serve as an outside compensation consultant. The Compensation Committee has considered whether the work of MMA as a compensation consultant has raised any conflict of interest, taking into account the following factors: (i) the amount of fees paid by us to MMA as a percentage of the firm’s total revenue; (ii) the provision of other services to us by MMA; (iii) MMA’s policies and procedures that are designed to prevent conflicts of interest; (iv) any business or personal relationship of the individual compensation advisors with any member of the Compensation Committee; (v) any business or personal relationship of MMA or the individual compensation advisors employed by the firm with any of our executive officers; and (vi) any of our stock owned by the individual compensation advisors employed by the firm. Based on the above factors, the Compensation Committee has concluded that the work of MMA and the individual compensation advisors employed by MMA as compensation consultants to us has not created any conflict of interest. Going forward, the Compensation Committee intends to assess the independence of any of our compensation advisers consistent with applicable NASDAQ listing standards.

MMA was involved with the process of selecting an appropriate peer group for us and in collecting and analyzing compensation data of the companies within our peer group and, if the data from our peer group is insufficient for a specific individual, from other market surveys. Our Compensation Committee determined our peer group in May of 2016 based on factors that were relevant at the time of the determination. This peer data was then used by the Compensation Committee in late 2016 and early 2017 as a tool to determine appropriate compensation levels for our executive officers for the 2017 calendar year. For the purpose of determining compensation levels of our executive officers for the 2017 calendar year, our peer group was comprised of 20 companies that were selected primarily based on their similarities to Senomyx, as of the time that the survey was performed, with respect to

revenue, market capitalization, industry, nature of operations, the overlapping labor market for top management talent, number of employees and location. For instance, at the end of May 2016, our market capitalization was approximately $127 million. In addition, during the immediately preceding fiscal year we had approximately $24.8 million in revenue and we ended 2015 with approximately 90 full-time employees. Therefore, following best practices, our peer group was mostly comprised of companies with revenue of less than $50 million for the most recently completed fiscal year, market capitalization of less than $500 million, and less than 200 employees. Most of the companies in our peer group that did not meet all of the parameters were companies that were included in our peer group during the preceding year and that the Compensation Committee still believed were appropriate although they did not necessarily meet all of the parameters as of the date of the survey. With respect to company location and type of business, 15 of the 20 companies in our peer group were located in California and the companies were primarily life science companies.

The specific list of companies that the Compensation Committee considered as our peers for purposes of determining compensation levels of our executive officers for the 2017 calendar year was as follows:


Amyris, Inc.	Geron Corp.	Rigel Pharmaceuticals, Inc.
Anika Therapeutics Inc.	Inovio Pharmaceuticals, Inc.	Sangamo Therapeutics, Inc.
ArQule, Inc.	Orexigen Therapeutics, Inc.	Sorrento Therapeutics, Inc.
Array BioPharma, Inc.	Organovo Holdings, Inc.	TerraVia Holdings, Inc.
BioAmber, Inc.	Peregrine Pharmaceuticals, Inc.	Vical, Inc.
Codexis, Inc.	Progenics Pharmaceuticals, Inc.	Xenoport, Inc.
Cytokinetics	Raptor Pharmaceuticals Corp.

In determining the 2017 compensation for our executive officers, we believe that the practices of the companies in the compensation peer group provide our Compensation Committee with relevant compensation information, not only because of the similarity of their business models and financial characteristics, but because several of these companies have similar organizational structures and compete with us for executive talent. The Compensation Committee will continue to evaluate our peer group companies on an ongoing basis when it makes determinations about the compensation of our executive officers in the future.

For purposes of determining compensation levels of our executive officers for the current 2018 calendar year, during May 2017 the Compensation Committee undertook a similar process and also utilized the services of MMA to select an appropriate peer group for the Company and to collect and analyze compensation data of the companies within our peer group.

To aid the Compensation Committee in performing its duties, our Chief Executive Officer provides recommendations concerning the compensation of the executive officers, excluding himself. Our CEO reviews and approves the individual performance goals of our executive officers (other than his own goals), monitors their progress in completing these goals, and conducts an annual performance evaluation for each executive officer. These assessments form the basis of his recommendations to the Compensation Committee with respect to the compensation of our executive officers. Although the Compensation Committee considers these recommendations in its deliberations, it exercises its own independent judgment in determining the compensation of our executive officer.

Additionally, our Chief Executive Officer, with the assistance of the entire management team, provides the Compensation Committee with the management team’s analysis of annual corporate goal achievement. The Compensation Committee excludes the Chief Executive Officer during the specific portions of any meeting when the committee discusses the Chief Executive Officer’s annual performance or considers and determines his base salary, annual performance based bonus or new equity awards.

Components of Executive Compensation Program

The Company’s executive compensation program for the executive officers includes:

•

Base salaries;

•

Annual performance based cash bonus awards;

•

Long-term equity awards in the form of stock options and through participation in our employee stock purchase plan; and

•

Other benefits, including severance and change-in-control benefits.

Base Salary

The base salaries of our executive officers are reviewed annually by the Compensation Committee and adjusted when necessary to reflect individual roles and performance and the competitive market. Base salaries represent a fixed component of our executive compensation program that are intended to keep us competitive with the market while remaining cost effective and providing security to our executive officers as a predictable stream of income. The Compensation Committee considers many factors, including the Company’s overall financial and corporate performance, the individual executive’s performance, qualifications and experience, competitive pay practices for base salary, prevailing market conditions, pay parity and a subjective assessment of the level and scope of responsibilities of the individual compared to persons performing similar roles at companies within the peer group.

In February 2017, Mr. Poyhonen received an increase to his base salary of 3.3%, effective January 1, 2017. Mr. Rogers and Ms. Wicker each received an increase in their respective base salaries of 2.7%, effective January 1, 2017. Ms. Lee received an increase in her base salary of 7.7%, effective January 1, 2017, in recognition of her promotion to Senior Vice President.

In February 2018, the Compensation Committee reviewed current base salaries for each of our executive officers in the context of the Company’s performance in 2017, the budget for 2018, and benchmark data at the 50 ^th percentile for our peer group. The Compensation Committee approved a 2.7% annual base salary increase for each of Mr. Poyhonen and Ms. Wicker, a 3.3% annual base salary increase for Ms. Lee and a 6.0% annual salary increase for Mr. Humphrey, effective January 1, 2018.

Annual Performance-Based Bonus

The Company’s performance based cash bonus awards are designed to provide incentives to executives to effectively pursue and achieve the difficult research and development, commercial and financial goals established by the Board. These goals are key to the success of our business and are intended to drive the achievement of both near-term and long-term objectives in a way that is aligned with the interests of our stockholders.

2017 Bonus Plan. In February 2017, our Compensation Committee approved the 2017 Bonus Plan under which our executive officers were provided with the opportunity to earn bonus payments conditioned upon the achievement of specified corporate goals. Under the 2017 Bonus Plan, each individual was assigned a target and range of bonus opportunity, calculated as a percentage of that individual’s 2017 base salary, based on the person’s role and title in the Company.

Under the 2017 Bonus Plan, the range of bonus opportunity as a percentage of 2017 base salary for each of our named executive officers was as follows:


		Bonus Opportunity Range
Name	Title	Threshold			Target			Maximum
John Poyhonen	President, Chief Executive Officer		30	%		60	%		90	%
Dave Humphrey	Vice President, Finance		20	%		40	%		60	%
Catherine Lee	Senior Vice President, General Counsel and Corporate Secretary		20	%		40	%		60	%
Sharon Wicker	Senior Vice President and Chief Commercial Development Officer		20	%		40	%		60	%
Antony E. Rogers ⁽¹⁾	Former Senior Vice President and Chief Financial Officer		20	%		40	%		60	%

(1)	Mr. Rogers resigned from his position of SVP, Chief Financial Officer, effective as of July 28, 2017.

Under the terms of our 2017 Bonus Plan, the payout for all of our executive officers was calculated entirely based on our achievement of corporate goals during 2017 and a minimum corporate goal achievement of greater than or equal to 50% was required for an executive to earn any performance-based cash bonus. The actual payment was determined by looking separately at R&D goals and financial and commercial goals. For R&D goals, the weighted bonus payment was based on a linear continuum from 1-50%, and for attainment above 50%, a two for one weighted payout could be earned with a maximum of 150%. For financial and commercial goals, a performance matrix was used that set a minimum threshold requirement of 85% goal achievement resulting in 70% weighted target payout; a target of 100% goal achievement resulting in 100% weighted target payout and a goal achievement of 120% resulting in 150% weighted target payout. However, it is also important to note that the Compensation Committee retained broad discretion to modify the 2017 Bonus Plan at any time, including the methodology for calculating the specific bonus amounts. The Compensation Committee could have also, in its sole discretion, determined to either increase the payout under the 2017 Bonus Plan for extraordinary achievement or to reduce payout if economic and business conditions warranted.

Our corporate goals are collectively designed to be stretch goals intended to be very challenging but attainable (i.e., viewed by Senomyx as 100% goal achievement being attainable only rarely and substantially less than 50% of the time). 100% goal achievement would represent an extremely high level of success in our discovery and development programs coupled with achievement in our numerous financial and commercial goals. For 2017, our corporate performance objectives were a combination of commercialization and financial goals, which represented 55% of our corporate performance objectives, and discovery and development goals, which represented the remaining 45% of our corporate performance objectives. In setting these financial and non-financial goals and their relative weights, our Compensation Committee considered the Company’s strategic vision and key areas necessary to our growth and financial success.

The details of our 2017 corporate goals are as follows:


Commercialization and Financial Goals	Goal Weighting
Generate commercial revenues in line with internal business objectives		10	%
Generate development revenues in line with internal business objectives		15	%
Achieve fiscal year 2017 net operating results in line with internal business objectives		10	%
Achieve 2017 year-end cash and investment balance in line with internal business objectives to support long term business objectives		20	%
Subtotal		55	%


Discovery and Development Goals	Goal Weighting
Continue with targeted synthetic sweet program discovery and development in support of future direct sales opportunities		7.5	%
Complete 2017 research plan for natural sweet modifiers and natural high potency sweetener		35	%
Complete 2017 salt modifier research plan		2.5	%
Subtotal		45	%
TOTAL		100.0	%

There were four components to the commercialization and financial portion of the corporate goals. Three of the components, those relating to generation of commercial and development revenues and net operating results, required at least 85% minimum threshold achievement, and the other, relating to year-end cash and investment balance required at least 75% minimum threshold achievement, to receive credit for goal achievement of such goal. The discovery and development goals did not contain specific minimum thresholds in order to measure credit for partial goal achievement, and goal achievement was evaluated by the Compensation Committee based on the Compensation Committee’s subjective assessment of Senomyx’s progress towards the achievement of a specific goal.

In February 2018, the Compensation Committee and the Board assessed the Company’s performance during the 2017 fiscal year against the 2017 corporate performance goals and determined that the overall corporate goal achievement was 90% which resulted in a 97.5% target bonus.

2018 Bonus Plan. In February 2018, the Compensation Committee approved our 2018 Executive Bonus Plan, or 2018 Bonus Plan. Under the 2018 Bonus Plan, all of our executive officers are provided with the opportunity to earn bonus payments conditioned upon the achievement of specified corporate metrics, which are intended to support our achievement of both near-term and long-term objectives. Under the 2018 Bonus Plan, each individual is assigned a target and range of bonus opportunity, calculated as a percentage of that individual’s 2018 base salary, based on the person’s role and title in the Company.

Under the 2018 Bonus Plan, the range of bonus opportunity expressed as a percentage of 2018 base salary for each of our named executive officers is as follows:


Name	Title	Threshold			Target			Maximum
John Poyhonen	President, Chief Executive Officer		30	%		60	%		90	%
Dave Humphrey	Vice President, Finance		20	%		40	%		60	%
Catherine Lee	Senior Vice President, General Counsel and Corporate Secretary		20	%		40	%		60	%
Sharon Wicker	Senior Vice President and Chief Commercial Development Officer		20	%		40	%		60	%

Under the 2018 Bonus Plan, the Compensation Committee retains the discretion to pay bonus awards in full or in part in the form of cash or as stock awards under our 2013 Equity Plan, or any similar equity incentive plan that we subsequently adopt. In the event that the Compensation Committee elects to pay a bonus under the 2018 Bonus Plan in the form of a stock award, the Compensation Committee will have discretion to determine the specific form and number of such awards that would be equivalent to the dollar value of any bonus payable under the terms of the 2018 Bonus Plan.

Long-Term Equity-Based Incentives

Stock Option Awards

Our long-term equity-based incentives, in the form of annual stock option awards, help ensure that executive officers will realize value only if our stockholders realize value on their shares. Stock options also foster retention of key executives since the awards generally vest a period of time and have a 10-year term. Our stock option awards for employees, including our executive officers, typically vest 25% at the end of the first year following the date of the award and 1/48 ^th per month thereafter through a four year period and have a 10 year term. We believe this vesting schedule promotes employee retention, and we will continue to utilize this vesting schedule for new stock option awards to all employees during 2018.

Stock options granted to our executive officers are approved by the Compensation Committee and, since December 2006, are granted effective as of the 15 ^th day of the month following the date of approval (or the next business day if the 15 ^th is not a business day); although the Compensation Committee retains the discretion to grant stock options as of any date. Prior to December 2006, stock options were generally granted effective as of the date of approval. Stock options granted to our executive officers are incentive stock options, to the extent permissible under the Internal Revenue Code, and commence vesting upon the effective date of grant. Generally, 25% of the shares subject to the stock options vest one year from the effective date of grant and the remainder of the shares vest in equal monthly installments over the 36 months thereafter, subject to acceleration of vesting in certain circumstances. As noted above, the stock options expire ten years from the effective date of grant. The exercise price per share of each stock option granted to our executive officers is equal to the fair market value of our common stock on the effective date of grant, which is deemed to be equal to the closing sales price of our common stock as reported on the NASDAQ Global Market on the last market trading day prior to the effective date of grant.

In general, each executive officer receives stock option grants in connection with his or her hire or promotion, and annually in the first quarter of each year. The size of each annual grant is typically based on an analysis of the following key factors for each executive officer:

•

corporate and individual performance against goals;

•

our stated compensation philosophy;

•

the emphasis placed on equity in the mix of total compensation;

•

the scope, responsibility and business impact of the executive officer’s position; and

•

benchmarking against our peer group and market survey data, including an analysis of option plan utilization percentages.

In February 2017, the Compensation Committee approved annual stock option grants to our executive officers tied to 2016 performance. The size of these annual stock option grants was based on the analysis described above. Stock option grants made during 2017 to our named executive officers are reflected in the Grants of Plan-Based Awards Table and outstanding stock option awards to named executive officers as of December 31, 2017 are reflected in the Outstanding Equity Awards at Fiscal Year-End Table.

Employee Stock Purchase Plan

During 2004, we adopted the 2004 Employee Stock Purchase Plan, as amended in 2013, or the 2004 ESPP. The 2004 ESPP allows all eligible employees to purchase shares of our common stock at the lower of: (i) 85% of the fair market value on the first day of a two-year offering period; or (ii) 85% of the fair market value on the last date of each six-month purchase period within the two-year offering period, with the objective of allowing employees to profit when the value of our common stock increases over time. During 2017, our named executive officers purchased an aggregate of 60,909 shares of our common stock at a weighted average price of $0.67 per share under the terms of the 2004 ESPP.

Severance and Change in Control Payments

We believe the interests of stockholders will be best served if the interests of our executive officers are aligned with them. By offering change in control benefits we believe we will eliminate the reluctance of executive officers to pursue potential change in control transactions that may be in the best interests of stockholders. However, these agreements only provide for benefits if the individual’s employment with the Company is actually or effectively terminated following a change-in-control transaction. Our agreements do not include any benefits solely as a result of a change-in-control. We also believe severance and change in control benefits are an essential element of our executive compensation package and assist us in recruiting and retaining talented individuals. As such, we have entered into employment agreements containing severance benefits and change in control agreements with each of our named executive officers, the terms of which are described under the headings “Employment and Change in Control Agreements” and “Potential Payments Upon Termination or Change in Control.”

Sabbatical Leave Benefit

Under a legacy arrangement, all employees who commenced employment with us on or before February 12, 2004 are eligible for four weeks of paid sabbatical after four years of employment with Senomyx. Employees who joined Senomyx after February 12, 2004 are not eligible for this benefit. Mr. Poyhonen is eligible for this program, but has not taken any paid sabbatical leave to-date. Mss. Lee and Wicker and Mr. Humphrey are not eligible for this benefit. If an eligible employee should leave Senomyx without using all or part of his or her sabbatical, the employee will be paid out their remaining sabbatical at the time of separation from the Company.

Other Benefits

We provide benefits such as an opportunity to participate in our 401(k) savings/retirement plan, medical, dental and life insurance and disability coverage to all our employees, including our executive officers. We also maintain a 401(k) matching program available to all employees, including executive officers. Under the terms of the 401(k) matching program, we will match 50% of employee participant contributions up to 3% of salary, resulting in a maximum match of not more than 1.5% of the employee participants’ salary (subject to IRS and plan limitations). Contribution matches under the 401(k) matching program are subject to a four-year vesting schedule measured from the date of an individual’s commencement of employment with us. Therefore, the 401(k) matching contributions for all of our named executive officers are now fully vested, with the exception of Ms. Lee who joined Senomyx in 2014. We also provide personal paid time off and other paid holidays to all employees, including our executive officers, which are comparable to those provided at similar companies.

Accounting and Tax Considerations

Our Compensation Committee considers the deductibility of executive compensation under Section 162(m) of the Code in designing, establishing and implementing our executive compensation policies and practices. Section 162(m) generally prohibits us from deducting any compensation over $1 million per taxable year paid to certain of our named executive officers unless, under tax laws in effect prior to January 1, 2018, such compensation is treated as “performance-based compensation” within the meaning of Section 162(m). The Tax Cuts and Jobs Act (the “Tax Act”), among other changes, repealed the exception from the deduction limit under Section 162(m) for performance-based compensation effective for taxable years beginning after December 31, 2017, such that compensation paid to our covered executive officers in excess of $1 million will not be deductible unless it qualifies for transition relief applicable to certain arrangements in place as of November 2, 2017 that are not materially modified after that date. As the cash compensation paid by us to our named executive officers for taxable years beginning before January 1, 2018 has below $1 million and the Compensation Committee believes that stock options granted under the 2004 and 2013 Equity Plans to our named executive officers meet the requirements for treatment as performance-based compensation, the Compensation Committee believes that Section 162(m) will not affect the tax deductions available to Senomyx with respect to the compensation granted to its named executive officers for taxable years beginning before January 1, 2018. However, because of ambiguities and uncertainties as to the application and interpretation of Section 162(m) as revised by the Tax Act, including the uncertain scope of the transition relief adopted in connection with repealing Section 162(m)’s performance-based compensation exception, no assurance can be given that previously granted compensation intended to satisfy the requirements for performance-based compensation will in fact qualify for such exception. The Compensation Committee will administer any awards granted prior to November 2, 2017 which qualify as performance-based compensation under Section 162(m), as amended by the Tax Act, in accordance with the transition rules applicable to binding contracts in effect on November 2, 2017, and will have the sole discretion to revise compensation arrangements to conform with the Tax Act and our Compensation Committee’s administrative practices, all without obtaining further stockholder approval. In addition, our Compensation Committee reserves the right to modify compensation that was initially intended to be exempt from the Section 162(m) deduction limit when it was granted if the Compensation Committee determines that such modifications are consistent with our business needs. In determining the form and amount of compensation for our named executive officers, the Compensation Committee will continue to consider all elements of the cost of such compensation, including the potential impact of Section 162(m). While the Compensation Committee considers the deductibility of awards as one factor in determining executive compensation, the Compensation Committee also looks at other factors in making its decisions and retains the flexibility to award compensation that it determines to be consistent with the goals of our executive compensation program even if the awards are not deductible by us for tax purposes.

Summary of Compensation

The following table sets forth in summary form information concerning the compensation that we paid during the fiscal years ended December 31, 2017, 2016 and 2015 to our named executive officers.

Employment

and Change in Control Agreements

We have entered into employment agreements with Messrs. Poyhonen and Humphrey and Mss. Lee and Wicker. The employment agreements set forth the applicable executive’s initial base salary and the terms of an initial stock option grant. Each of our named executive officers is entitled to receive all customary and usual fringe benefits provided to our executives.

In connection with Mr. Poyhonen’s appointment as our Chief Executive Officer, we entered into a new employment agreement with him in September 2013. Mr. Poyhonen’s employment agreement provides that we may terminate his employment at will upon 30 days’ notice. However, if we terminate his employment for any reason other than cause, he will be entitled to one year’s salary from the date of termination.

Ms. Wicker’s employment agreement provides that we may terminate her employment at will upon 30 days’ notice. However, if we terminate her employment for any reason other than cause, she will be entitled to six months’ salary from the date of termination.

On October 10, 2006, we entered into change in control agreements with Mr. Poyhonen and Ms. Wicker. The change in control agreements with these named executive officers were amended in December 2008 for purposes of compliance with regulations under Section 409A of the Internal Revenue Code. We subsequently amended our change in control agreements with Mr. Poyhonen in September 2009 in connection with his promotion at that time.

In connection with Mr. Poyhonen’s appointment as our Chief Executive Officer, we amended our change in control agreement with him again in September 2013. Mr. Poyhonen’s change in control agreement provides that if his employment is terminated by us without cause or by him for good reason within one month prior or 18 months after a change in control, Mr. Poyhonen’s stock options will immediately vest in full and he will be entitled to a lump sum payment equal to 150% of the sum of his base salary in effect on the date of termination and his last annual bonus received prior to the date of termination.

We entered into a change in control agreement with Ms. Lee on May 28, 2014, which was subsequently amended on February 19, 2016. The change in control agreements for Mss. Lee and Wicker provide that if the executive’s employment is terminated by us without cause or by the executive for good reason within one month prior or 18 months after a change in control, the executive will be entitled to immediate vesting in full of the executive’s stock options and a lump sum payment equal to 100% of the sum of the executive’s base salary in effect on the date of termination and the executive’s last annual bonus received prior to the date of termination.

On June 9, 2017, we entered into a change in control agreement with Mr. Humphrey. Mr. Humphrey’s change in control agreement provides that if his employment is terminated by us without cause or by him with good reason within one month prior or 18 months after a change in control, Mr. Humphrey’s stock options will immediately vest in full and he will be entitled to receive a lump sum payment equal to 75% of the sum of his base salary in effect on the date of termination and his last annual bonus received prior to the date of termination.

All of the change in control agreements also provide for reimbursement for health insurance benefits elected by the executives for themselves and their families under the Consolidated Omnibus Reconciliation Act of 1985 (COBRA) until the earliest of 12 months following termination, the expiration of continuation coverage under COBRA or the date the executive becomes eligible for health insurance benefits with a subsequent employer. All benefits received under any of the change in control agreements are subject to delivery of a general release in favor of Senomyx and payments under the agreements may be reduced in order to provide for the best after tax treatment of the payments in the event the payments are subject to the excise taxes imposed by Section 4999 of the Internal Revenue Code.

In establishing the triggering events for payment obligations in connection with termination events under our employment and change in control agreements with our named executive officers, the Compensation Committee considered several factors. Payments upon termination by us without cause are provided as a recruiting and retention tool and because we consider such a termination to be generally beyond the control of a terminated employee and a termination that under different circumstances would not have occurred. The termination benefits are intended to ease the consequences to an employee of an unexpected termination of employment. Senomyx benefits by requiring a general release from terminated employees. Payments and option acceleration upon terminations in connection with a change in control are intended to mitigate the distraction and loss of key management personnel that may occur in connection with rumored or actual fundamental corporate changes. Such payments protect stockholder interests by enhancing employee focus during rumored or actual change in control activity through incentives to remain with Senomyx despite uncertainties while a transaction is under consideration or pending, assurance of severance and benefits for terminated employees and access to the equity component of total compensation after a change in control.

Potential Payments Upon Termination or Change-in-Control

The following table sets forth potential payments to our named executive officers upon various termination or change in control events assuming such events occurred as of December 31, 2017.

(1)

Amounts shown for option awards represent the value of unvested options that would have accelerated if the named executive officer was terminated on December 31, 2017 in connection with a change in control based on the difference between the closing price of our common stock on December 31, 2017, which was $1.30 per share, and the exercise price of the respective options.

Mr. Rogers, our Former SVP and Chief Financial Officer, resigned effective as of July 28, 2017. On such date, Mr. Rogers was paid all accrued and unused paid time off earned through such date and all unused sabbatical time, less deductions and withholdings. We entered into a consulting services agreement with Mr. Rogers, which began on July 28, 2017 and terminated on December 22, 2017. During such period, Mr. Rogers’ issued and outstanding stock options under the 2004 Equity Plan and the 2013 Equity Plan continued to vest. Mr. Rogers also received aggregate cash compensation of approximately $12,115 in exchange for up to ten hours of service to the Company per month. In addition, the exercise period for all of Mr. Rogers’ vested and unexercised stock options was extended until December 31, 2018.

Grants of Plan-Based Awards

Before January 1, 2014, we granted stock options to our executive officers under the 2004 Equity Plan. Since January 1, 2014, we have granted stock options to our executive officers under the 2013 Equity Plan. As of March 1, 2018, options to purchase a total of 9,673,570 shares were outstanding under the 2004 Equity Plan and 2013 Equity Plan, and a total of 2,802,819 shares remained available for grant under the 2013 Equity Plan.

All stock options granted to the executive officers are incentive stock options, to the extent permissible under the Internal Revenue Code. Generally, 25% of the shares subject to options vest one year from the date of hire and the remainder of the shares vest in equal monthly installments over the 36 months thereafter, subject to acceleration of vesting pursuant to the change in control agreements described in Employment and Change in Control Agreements . Options expire ten years from the date of grant.

The following table provides information regarding grants of plan-based awards to the named executive officers in the fiscal year ended December 31, 2017.

P OLICIES AND P ROCEDURES WITH R ESPECT TO R ELATED P ARTY T RANSACTIONS

Our Board of Directors is committed to upholding the highest legal and ethical conduct in fulfilling its responsibilities and recognizes that related party transactions can present a heightened risk of potential or actual conflicts of interest. Accordingly, as a general matter, it is Senomyx’s preference to avoid related party transactions.

Our Audit Committee charter requires that members of the Audit Committee, all of whom are independent directors, review and approve all related party transactions for which such approval is required under applicable law, including SEC rules and NASDAQ listing standards. A related party transaction includes any transaction, arrangement or relationship involving an amount that exceeds $120,000 in which Senomyx is a participant and in which any of the following persons has or will have a direct or indirect interest: any executive officer, director, or more than 5% stockholder of Senomyx, including any of their immediate family members, and any entity owned or controlled by such persons.

In addition, the Audit Committee is responsible for reviewing and investigating any matters pertaining to the integrity of management, including conflicts of interest and adherence to our Code of Business Conduct and Ethics. Under our Code of Business Conduct and Ethics, directors, officers and all other members of the workforce are expected to avoid any relationship, influence or activity that would cause or even appear to cause a conflict of interest.

C ERTAIN R ELATIONSHIPS AND R ELATED T RANSACTIONS

During the fiscal year ended December 31, 2017, we granted options to purchase an aggregate of 1,045,550 shares of our common stock to our directors and executive officers, with exercise prices ranging from $0.87 to $1.02 per share.

Our Bylaws provide that we will indemnify our directors and executive officers, and may indemnify other officers, employees and other agents, to the fullest extent permitted by law. Our Bylaws also permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in connection with their services to us, regardless of whether our Bylaws permit such indemnification. We have obtained a policy of directors’ and officers’ liability insurance.

We have entered, and intend to continue to enter, into indemnification agreements with our directors and executive officers, in addition to the indemnification provided for in our Bylaws. These agreements, among other things, require us to indemnify our directors and executive officers for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of their services as one of our directors or executive officers, or any of our subsidiaries or any other company or enterprise to which the person provides services at our request.

H OUSEHOLDING OF P ROXY M ATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers, banks or other agents) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials and annual meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Material or set of annual meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of broker, banks or other agents with account holders who are stockholders of Senomyx will be “householding” our proxy materials. A single Notice of Internet Availability of Proxy Material or set of annual meeting materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker, bank or other agent that it 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 Notice of Internet Availability of Proxy Material or set of annual meeting materials, please notify your broker, bank or other agent, and direct a written request for the separate Notice of Internet Availability of Proxy Material or set of annual meeting materials to 4767 Nexus Centre Drive, San Diego, California 92121, Attn: Corporate Secretary, or contact Catherine Lee at (858) 646-8300. Stockholders whose shares are held by their broker, bank or other agent as nominee and who currently receive multiple copies of the Notice of Internet Availability of Proxy Material or set of annual meeting materials at their address that would like to request “householding” of their communications should contact their broker, bank or other agent.

OTHER MATTERS

Our Board of Directors knows of no other matters that will be presented for consideration at the annual meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.
