PROXY STATEMENT FOR THE 2021 ANNUAL MEETING OF STOCKHOLDERS

 

 

June 3, 2021

INFORMATION ABOUT SOLICITATION AND VOTING

The accompanying proxy is solicited on behalf of the Board of Directors of Sutro Biopharma, Inc. (Sutro Biopharma or the Company) for use at Sutro Biopharma’s 2021 Annual Meeting of Stockholders (Annual Meeting) to be held via a virtual meeting due to the public health and travel concerns our stockholders may have and recommendations that public health officials have issued and may issue in light of the ongoing coronavirus (COVID-19) situation. You will be able to participate in the Annual Meeting and vote during the Annual Meeting via live webcast by visiting www.virtualshareholdermeeting.com/STRO2021 on Thursday, June 3, 2021 at 10:00 a.m. (Pacific Time), and any adjournment or postponement thereof. You will need the control number included on your proxy card or voting instruction form, or included in the e-mail to you if you received the proxy materials by e-mail, as such number will be required in order for stockholders to gain access to the virtual meeting.  

This proxy statement and the accompanying form of proxy were first mailed to stockholders on or about April 29, 2021. An Annual Report on Form 10-K for the year ended December 31, 2020 is enclosed with this proxy statement. An electronic copy of this proxy statement and Annual Report on Form 10-K are available at www.proxyvote.com.

GENERAL INFORMATION ABOUT THE MEETING

Purpose of the Meeting

At the meeting, stockholders will act upon the proposals described in this proxy statement. In addition, we will consider any other matters that are properly presented for a vote at the meeting. We are not aware of any other matters to be submitted for consideration at the meeting. If any other matters are properly presented for a vote at the meeting, the persons named in the proxy, who are officers of the company, have the authority in their discretion to vote the shares represented by the proxy.

Record Date; Quorum

Only holders of record of common stock at the close of business on April 12, 2021, the record date, will be entitled to vote at the meeting. At the close of business on April 12, 2021, 46,103,739 shares of common stock were outstanding and entitled to vote.

The holders of a majority of the voting power of the shares of stock entitled to vote at the meeting as of the record date must be present or represented by proxy at the meeting in order to hold the meeting and conduct business. This presence is called a quorum. Your shares are counted as present at the meeting if you are present and vote online at the virtual meeting or if you have properly submitted a proxy.

GENERAL PROXY INFORMATION

Voting Rights; Required Vote

Each holder of shares of common stock is entitled to one vote for each share of common stock held as of the close of business on April 12, 2021, the record date. You may vote all shares owned by you at such date, including (1) shares held directly in your name as the stockholder of record and (2) shares held for you as the beneficial owner in street name through a broker, bank, trustee or other nominee. Dissenters’ rights are not applicable to any of the matters being voted on.

Stockholder of Record: Shares Registered in Your Name. If on April 12, 2021, your shares were registered directly in your name with our transfer agent, American Stock Transfer & Trust Company, LLC, then you are considered the stockholder of record with respect to those shares. As a stockholder of record, you may vote at the meeting, or vote in advance through the internet or by telephone, or if you request to receive paper proxy materials by mail, by filling out and returning the proxy card.

Beneficial Owner: Shares Registered in the Name of a Broker or Nominee. If on April 12, 2021, your shares were held in an account with a brokerage firm, bank or other nominee, then you are the beneficial owner of the shares held in street name. As a beneficial owner, you have the right to direct your broker on how to vote the shares held in your account, and your broker has enclosed or provided voting instructions for you to use in directing it on how to vote your shares. Because the brokerage firm, bank or other nominee that holds your shares is the stockholder of record, if you wish to attend the meeting and vote your shares, you must obtain a valid proxy from the firm that holds your shares giving you the right to vote the shares at the meeting.

Each director will be elected by a plurality of the votes cast at the meeting. This means that the three individuals nominated for election to the Board of Directors at the meeting receiving the highest number of “FOR” votes will be elected. You may either vote “FOR” one, two or all of the nominees or “WITHHOLD” your vote with respect to one, two or all of the nominees. You may not cumulate votes in the election of directors. Approval of the ratification of the appointment of our independent registered public accounting firm will be obtained if the holders of a majority of the votes cast at the meeting vote “FOR” the proposal.

A proxy submitted by a stockholder may indicate that the shares represented by the proxy are not being voted (stockholder withholding) with respect to a particular matter. In addition, a broker may not be permitted to vote on shares held in street name on a particular matter in the absence of instructions from the beneficial owner of the stock (broker non-vote). The shares subject to a proxy which are not being voted on a particular matter because of either stockholder withholding or broker non-votes will count for purposes of determining the presence of a quorum, but are not treated as votes cast and, therefore, will have no effect on the election of directors, or the ratification of the appointment of Ernst & Young LLP. Abstentions are voted neither “for” nor “against” a matter, and, therefore, will have no effect on the election of directors or the ratification of the appointment of Ernst & Young LLP, but are counted in the determination of a quorum.

Recommendations of the Board of Directors on Each of the Proposals Scheduled to be Voted on at the Meeting

The Board of Directors recommends that you vote FOR the election of each of the Class III directors named in this proxy statement (Proposal 1) and FOR the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021 (Proposal 2).

None of the directors or executive officers has any substantial interest in any matter to be acted upon, other than elections to office with respect to the directors nominated in Proposal 1.

Voting Instructions; Voting of Proxies

If you are a stockholder of record, you may:

 

 

vote online at the Annual Meeting – attend the Annual Meeting online and follow the instructions posted at www.virtualshareholdermeeting.com/STRO2021. You will need the control number included on your proxy card or voting instruction form, or included in the e-mail to you if you received the proxy materials by e-mail;

 

 

vote through the internet or by telephone – in order to do so, please follow the instructions shown on your proxy card; or

 

 

vote by mail – if you request or receive a paper proxy card and voting instructions by mail, simply complete, sign and date the proxy card and return it as soon as possible before the meeting in the envelope provided.

2


Votes submitted through the internet or by telephone must be received by 11:59 p.m., Eastern Time, on June 2, 2021. Submitting your proxy, whether by telephone, through the internet or by mail if you requested or received a paper proxy card, will not affect your right to vote online should you decide to attend the virtual meeting. If you are not the stockholder of record, please refer to the voting instructions provided by your nominee to direct how to vote your shares. For Proposal 1, you may either vote “FOR” all of the nominees to the Board of Directors, or you may withhold your vote from any nominee you specify. For Proposal 2, you may vote “FOR” or “AGAINST” or “ABSTAIN” from voting. Your vote is important. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure that your vote is counted.

All proxies will be voted in accordance with the instructions specified on the proxy card. If you sign a physical proxy card and return it without instructions as to how your shares should be voted on a particular proposal at the meeting, your shares will be voted in accordance with the recommendations of our Board of Directors stated above.

If you do not vote and you hold your shares in street name, and your broker does not have discretionary power to vote your shares, your shares may constitute “broker non-votes” (as described above) and will not be counted in determining the number of shares necessary for approval of the proposals. However, shares that constitute broker non-votes will be counted for the purpose of establishing a quorum for the meeting.

If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. To make certain all of your shares are voted, please follow the instructions included on each proxy card and vote each proxy card by telephone, through the internet or by mail. If you requested or received paper proxy materials by mail, please complete, sign, date and return each proxy card to ensure that all of your shares are voted.

Expenses of Soliciting Proxies

We will pay the expenses associated with soliciting proxies. Following the original distribution and mailing of the solicitation materials, we or our agents may solicit proxies by mail, email, telephone, facsimile, by other similar means, or in person. Our directors, officers and other employees, without additional compensation, may solicit proxies personally or in writing, by telephone, email or otherwise. Following the original distribution and mailing of the solicitation materials, we will request brokers, custodians, nominees and other record holders to forward copies of those materials to persons for whom they hold shares and to request authority for the exercise of proxies. In such cases, we, upon the request of the record holders, will reimburse such holders for their reasonable expenses. If you choose to access the proxy materials and/or vote through the internet, you are responsible for any internet access charges you may incur.

Revocability of Proxies

A stockholder of record who has given a proxy may revoke it at any time before the closing of the polls by the inspector of elections at the meeting by:

 

 

delivering to our Corporate Secretary (by any means, including facsimile) a written notice stating that the proxy is revoked;

 

 

signing and delivering a proxy bearing a later date;

 

 

voting again through the internet or by telephone; or

 

 

attending and voting online at the meeting by following the instructions posted at www.virtualshareholdermeeting.com/STRO2021 (although attendance at the meeting will not, by itself, revoke a proxy).

Please note, however, that if your shares are held of record by a brokerage firm, bank or other nominee, and you wish to revoke a proxy, you must contact that firm to revoke or change any prior voting instructions.

Voting Results

Voting results will be tabulated and certified by the inspector of elections appointed for the meeting. The final results will be tallied by the inspector of elections and filed with the SEC in a Current Report on Form 8-K within four business days of the meeting.

Implications of Being an “Emerging Growth Company” and “Smaller Reporting Company”

We are an “emerging growth company” as that term is used in the Jumpstart Our Business Startups Act of 2012, and a “Smaller Reporting Company” as defined under Rule 405 of the Securities Act of 1933, and, as such, have elected to comply with certain reduced public company reporting requirements. These reduced reporting requirements include reduced disclosure about the company’s executive compensation arrangements and no requirement to have non-binding advisory votes on executive compensation.

 

CORPORATE GOVERNANCE STANDARDS AND DIRECTOR INDEPENDENCE

We are committed to good corporate governance practices. These practices provide an important framework within which our Board of Directors and management pursue our strategic objectives for the benefit of our stockholders.

Corporate Governance Guidelines

Our Board of Directors has adopted Corporate Governance Guidelines that set forth expectations for directors, director independence standards, Board committee structure and functions, and other policies for the governance of the company. Our Corporate Governance Guidelines are available without charge on the investor relations section of our website at https://ir.sutrobio.com/corporate-governance/governance-overview.

Board Composition and Leadership Structure

The positions of Chief Executive Officer and Chair of our Board of Directors are held by two different individuals (William J. Newell and Connie Matsui, respectively). This structure allows our Chief Executive Officer to focus on our day-to-day business while our Chair leads our Board of Directors in its fundamental role of providing advice to and independent oversight of management. Our Board of Directors believes such separation is appropriate, as it enhances the accountability of the Chief Executive Officer to the Board of Directors and strengthens the independence of the Board of Directors from management.

Board’s Role in Risk Oversight

Our Board of Directors believes that open communication between management and the Board of Directors is essential for effective risk management and oversight. Our Board of Directors meets with our Chief Executive Officer and other members of the senior management team at quarterly Board of Director meetings, where, among other topics, they discuss strategy and risks in the context of reports from the management team and evaluate the risks inherent in significant transactions. While our Board of Directors is ultimately responsible for risk oversight, our Board committees assist the Board of Directors in fulfilling its oversight responsibilities in certain areas of risk. The Audit Committee assists our Board of Directors in fulfilling its oversight responsibilities with respect to risk management in the areas of internal control over financial reporting and disclosure controls and procedures. The Compensation Committee assists our Board of Directors in assessing risks created by the incentives inherent in our compensation policies. The Nominating and Governance Committee assists our Board of Directors in fulfilling its oversight responsibilities with respect to the management of corporate, legal and regulatory risk. The Science and Technology Committee assists our Board of Directors in fulfilling its oversight responsibilities with respect to our research and development and platform programs.

Director Independence

Our common stock is listed on the Nasdaq Global Market. Under the rules of the Nasdaq Stock Market, independent directors must constitute a majority of a listed company’s Board of Directors. In addition, the rules of the Nasdaq Stock Market require that, subject to specified exceptions, each member of a listed company’s Audit, Compensation and Nominating and Governance Committees must be an “independent director”. Under the rules of the Nasdaq Stock Market, a director will only qualify as an “independent director” if, in the opinion of that company’s Board of Directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Additionally, Compensation Committee members must not have a relationship with the listed company that is material to the director’s ability to be independent from management in connection with the duties of a Compensation Committee member.

Audit Committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (Exchange Act). In order to be considered independent for purposes of Rule 10A-3, a member of an Audit Committee of a listed company may not, other than in his or her capacity as a member of the Audit Committee, the Board of Directors or any other Board committee: (i) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (ii) be an affiliated person of the listed company or any of its subsidiaries.

Our Board of Directors has undertaken a review of the independence of each director and considered whether each director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, our Board of Directors determined that Connie Matsui, Michael Dybbs, John Freund, Joseph Lobacki, James Panek, Shalini Sharp, and Jon Wigginton representing seven of our nine incumbent directors, are “independent directors” as defined under the applicable rules and regulations of the SEC and the listing requirements and rules of the Nasdaq Stock Market. In making these determinations, our Board of Directors reviewed and discussed information provided by the directors and us with regard to each directors’ business and personal activities and relationships as they may relate to us and our management, including the beneficial ownership of our capital stock by each non-employee director and any affiliates.

Committees of Our Board of Directors

Our Board of Directors has established an Audit Committee, a Compensation Committee, a Nominating and Governance Committee and a Science and Technology Committee, each of which has the composition and responsibilities described below. Members serve on these committees until their resignation or until otherwise determined by our Board of Directors. Each of these committees has a written charter, copies of which are available without charge on the investor relations section of our website at https://ir.sutrobio.com/corporate-governance/governance-overview.

Audit Committee

 

Our Audit Committee is composed of Ms. Sharp, Dr. Freund, and Mr. Lobacki. Ms. Sharp is the Chair of our Audit Committee. The composition of our Audit Committee meets the requirements for independence under the current Nasdaq Stock Market and SEC rules and regulations. Each member of our Audit Committee is financially literate. In addition, our Board of Directors has determined that Ms. Sharp is an “audit committee financial expert” as defined in Item 407(d)(5)(ii) of Regulation S-K promulgated under the Securities Act. Our Audit Committee is directly responsible for, among other things:

 

selecting and hiring our independent registered public accounting firm;

 

the qualifications, independence and performance of our independent auditors;

 

the preparation of the audit committee report to be included in our annual proxy statement;

 

our accounting and financial reporting processes, including our financial statement audits and the integrity of our financial statements; and

 

reviewing and approving related-person transactions.

 

Compensation Committee

 

Our Compensation Committee is composed of Mr. Lobacki and Ms. Matsui. Mr. Lobacki is the Chair of our Compensation Committee. The composition of our Compensation Committee meets the requirements for independence under the current Nasdaq Stock Market and SEC rules and regulations. Our Compensation Committee is responsible for, among other things:

 

evaluating, recommending, approving and reviewing executive officer compensation arrangements, plans, policies and programs;

5


 

evaluating and providing input for non-employee director compensation arrangements for determination by the management team;

 

providing oversight for our cash-based and equity-based compensation plans; and

 

compliance with regulatory requirements associated with the compensation of directors, officers and employees.

The Compensation Committee has the sole authority and responsibility, subject to any approval by the Board of Directors which the Compensation Committee or legal counsel determines to be desirable or required by applicable law or the Nasdaq rules, to determine all aspects of executive compensation packages for the Chief Executive Officer and other executive officers. The Compensation Committee also makes recommendations to our Board of Directors regarding the form and amount of compensation of non-employee directors. The Compensation Committee may take into account the recommendations of the Chief Executive Officer with respect to compensation of the other executive officers, and the recommendations of the Board of Directors or any member of the Board of Directors with respect to compensation of the Chief Executive Officer and other executive officers.

The Compensation Committee engaged an independent executive compensation consulting firm, Frederick W. Cook & Co., Inc. (FW Cook), to evaluate our executive compensation and Board of Directors compensation program and practices and to provide advice and ongoing assistance on these matters for the fiscal year ended December 31, 2020. Specifically, FW Cook was engaged to:

 

provide compensation-related data for a peer group of companies to serve as a basis for assessing competitive compensation practices;

 

review and assess our current Board of Directors, Chief Executive Officer and other executive officer compensation policies and practices and equity profile, relative to market practices;

 

review and assess our current executive compensation program relative to market to identify any potential changes or enhancements to be brought to the attention of the Compensation Committee; and

 

review market practices regarding base salary, bonus and equity programs.

Representatives of FW Cook met informally with the Chair of the Compensation Committee and attended the regular meetings of the Compensation Committee, including executive sessions from time to time without any members of management present. During the fiscal year ended December 31, 2020, FW Cook worked directly with the Compensation Committee (and not on behalf of management) to assist the committee in satisfying its responsibilities and undertook no projects for management without the committee’s prior approval. The Compensation Committee has determined that none of the work performed by FW Cook during the fiscal year ended December 31, 2020 raised any conflict of interest.

Nominating and Governance Committee

Our Nominating and Governance Committee is composed of Ms. Matsui and Dr. Dybbs. Ms. Matsui is the Chair of our Nominating and Governance Committee. Our Nominating and Governance Committee is responsible for, among other things:

 

identifying, considering and recommending candidates for membership on our Board of Directors;

 

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

 

advising our Board of Directors on other corporate governance matters.

 

our compliance with legal and regulatory requirements;

Science and Technology Committee

Our Science and Technology Committee is composed of Dr. Dybbs, Mr. Panek and Dr. Wigginton. Dr. Dybbs is the Chair of our Science and Technology Committee. Our Science and Technology Committee is responsible for, among other things:

 

 

reviewing our overall scientific, research and development and platform strategy;

 

overseeing our research and development and platform programs;

 

reviewing external scientific research, discoveries and commercial developments, as appropriate; and

 

evaluating our overall intellectual property strategies.

Codes of Conduct and Ethics

Our Board of Directors has adopted a code of business conduct and ethics that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer and other executive and senior financial officers. We intend to disclose future amendments to certain provisions of our code of conduct, or waivers of these provisions, on our website or in public filings.

6


The full text of our code of conduct is posted on the investor relations section of our website at https://ir.sutrobio.com/corporate-governance/governance-overview.

Anti-hedging

We have adopted an Insider Trading Policy that that applies to all of our employees, officers and directors, including our Chief Executive Officer and other executive officers, which prohibits such individuals from purchasing financial instruments, or otherwise engaging in transactions, that hedge or offset, or are designed to hedge or offset, any decrease in market value of our common stock,  such as prepaid variable forward contracts, equity swaps, collars, forward sale contracts and exchange funds.

Compensation Committee Interlocks and Insider Participation

During 2020, Mr. Lobacki and Ms. Matsui served on our Compensation Committee. None of our current executive officers has served as a member of the Board of Directors, or as a member of the Compensation or similar committee, of any entity that has one or more executive officers who served on our Board of Directors or Compensation Committee during the fiscal year ended December 31, 2020.

Board and Committee Meetings and Attendance

The Board of Directors and its committees meet regularly throughout the year and also hold special meetings and act by written consent from time to time. During 2020, the Board of Directors held six meetings including telephonic meetings; the Audit Committee held four meetings; the Compensation Committee held four meetings; the Science and Technology Committee held two meetings; and the Nominating and Governance Committee held three meetings. During 2020, none of the directors attended fewer than 75% of the aggregate of the total number of meetings held by the Board of Directors during his or her tenure and the total number of meetings held by all committees of the Board of Directors on which such director served during his or her tenure. The independent members of the Board of Directors also meet separately without management directors on a regular basis to discuss such matters as the independent directors consider appropriate.

Board Attendance at Annual Stockholders’ Meeting

We invite and encourage each member of our Board of Directors to attend our annual meetings of stockholders. All of our directors attended our 2020 annual meeting of stockholders, which was held virtually.  We do not have a formal policy regarding attendance of our annual meetings of stockholders by the members of our Board of Directors.

Communication with Directors

Stockholders and interested parties who wish to communicate with our Board of Directors, non-management members of our Board of Directors as a group, a committee of the Board of Directors or a specific member of our Board of Directors (including our Chair) may do so by letters addressed to:

Sutro Biopharma, Inc.

c/o Corporate Secretary

310 Utah Avenue, Suite 150

South San Francisco, California, 94080

All communications by letter addressed to the attention of our Corporate Secretary will be reviewed by the Corporate Secretary and provided to the members of the Board of Directors unless such communications are unsolicited items, sales materials and other routine items and items unrelated to the duties and responsibilities of the Board of Directors.

Considerations in Evaluating Director Nominees

The Nominating and Governance Committee is responsible for identifying, considering and recommending candidates to the Board of Directors for Board membership. A variety of methods are used to identify and evaluate director nominees, with the goal of maintaining and further developing a diverse, experienced and highly qualified Board of Directors. Candidates may come to our attention through current members of our Board of Directors, professional search firms, stockholders or other persons.

The Nominating and Governance Committee will recommend to the Board of Directors for selection all nominees to be proposed by the Board of Directors for election by the stockholders, including approval or recommendation of a slate of director nominees to be proposed by the Board of Directors for election at each annual meeting of stockholders, and will recommend all director nominees to be appointed by the Board of Directors to fill interim director vacancies.

 

Our Board of Directors encourages selection of directors who will contribute to the company’s overall corporate goals. The Nominating and Governance Committee may from time to time review and recommend to the Board of Directors the desired qualifications, expertise and characteristics of directors, including such factors as business experience, diversity and personal skills in life sciences and biotechnology, finance, marketing, financial reporting and other areas that are expected to contribute to an effective Board of Directors. Exceptional candidates who do not meet all of these criteria may still be considered. In evaluating potential candidates for the Board of Directors, the Nominating and Governance Committee considers these factors in the light of the specific needs of the Board of Directors at that time.

In addition, under our Corporate Governance Guidelines, a director is expected to spend the time and effort necessary to properly discharge such director’s responsibilities. Accordingly, a director is expected to regularly attend meetings of the Board of Directors and committees on which such director sits, and to review prior to meetings material distributed in advance for such meetings. Thus, the number of other public company boards and other boards (or comparable governing bodies) on which a prospective nominee is a member, as well as his or her other professional responsibilities, will be considered. Also, under our Corporate Governance Guidelines, there are no limits on the number of three-year terms that may be served by a director. However, in connection with evaluating recommendations for nomination for reelection, the Nominating and Governance Committee considers director tenure. We value diversity on a company-wide basis but have not yet adopted a specific policy regarding Board diversity.

Stockholder Recommendations for Nominations to the Board of Directors

The Nominating and Governance Committee will consider properly submitted stockholder recommendations for candidates for our Board of Directors who meet the minimum qualifications as described above. The Nominating and Governance 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. A stockholder of record can nominate a candidate for election to the Board of Directors by complying with the procedures in Article I, Section 1.12 of our bylaws. Any eligible stockholder who wishes to submit a nomination should review the requirements in the bylaws on nominations by stockholders. Any nomination should be sent in writing to our Corporate Secretary, Sutro Biopharma, Inc., 310 Utah Avenue, Suite 150, South San Francisco, California, 94080. Submissions must include the full name of the proposed nominee, complete biographical information, a description of the proposed nominee’s qualifications as a director, other information specified in our bylaws, and a representation that the nominating stockholder is a beneficial or record holder of our stock. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected. These candidates are evaluated at meetings of the Nominating and Governance Committee and may be considered at any point during the year. If any materials are provided by a stockholder in connection with the recommendation of a director candidate, such materials are forwarded to the Nominating and Governance Committee.

Additional information regarding the process for properly submitting stockholder nominations for candidates for membership on our Board of Directors is set forth below under Stockholder Proposals to Be Presented at Next Annual Meeting.

PROPOSAL NO. 1

ELECTION OF CLASS III DIRECTORS

Our Board of Directors is divided into three classes. Each class serves for three years, with the terms of office of the respective classes expiring in successive years. Directors and director nominees in Class III will stand for election at this meeting. The terms of office of directors in Class I and Class II do not expire until the annual meetings of stockholders to be held in 2022 and 2023, respectively. Our Nominating and Governance Committee recommended to our Board of Directors, and our Board of Directors nominated Mr. Lobacki, Ms. Sharp and Mr. Petree, each an incumbent Class III director, for election as Class III directors at the Annual Meeting. At the recommendation of our Nominating and Governance Committee, our Board of Directors proposes that each of the Class III nominees be elected as a Class III director for a three-year term expiring at the annual meeting of stockholders to be held in 2024 and until such director’s successor is duly elected and qualified or until such director’s earlier resignation or removal.

Each director will be elected by a plurality of the votes present online at the virtual Annual Meeting or represented by proxy at the Annual Meeting and entitled to vote on the election of directors. This means that the three individuals nominated for election to the Board of Directors at the Annual Meeting receiving the highest number of “FOR” votes will be elected. You may either vote “FOR” one, two or all of the nominees or “WITHHOLD” your vote with respect to one, two or all of the nominees. Shares represented by proxies will be voted “FOR” the election of each of the Class III nominees, unless the proxy is marked to withhold authority to so vote. You may not cumulate votes in the election of directors. If any nominee for any reason is unable to serve, the proxies may be voted for such substitute nominee as the proxy holders, who are officers of our company, might determine. Each nominee has consented to being named in this proxy statement and to serve if elected. Proxies may not be voted for more than three directors.

PROPOSAL NO. 2

RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Our Audit Committee has selected Ernst & Young LLP as our principal independent registered public accounting firm to perform the audit of our financial statements for the fiscal year ending December 31, 2021. Ernst & Young LLP audited our financial statements for the fiscal years ended December 31, 2020 and 2019. We expect that representatives of Ernst & Young LLP will be present at the Annual Meeting, will be able to make a statement if they so desire and will be available to respond to appropriate questions.

At the Annual Meeting, the stockholders are being asked to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021. Although ratification by stockholders is not required by law, our Audit Committee is submitting the selection of Ernst & Young LLP to our stockholders because we value our stockholders’ views on our independent registered public accounting firm and as a matter of good corporate governance. If this proposal does not receive the affirmative approval of a majority of the votes cast on the proposal, the Audit Committee would reconsider the appointment. Notwithstanding its selection and even if our stockholders ratify the selection, our Audit Committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year if the Audit Committee believes that such a change would be in our best interests and the interests of our stockholders.

The following table presents fees for professional audit services rendered by Ernst & Young LLP for the audit of our annual financial statements for the years ended December 31, 2020 and 2019.

Executive Severance Plan

On March 17, 2021, we adopted an executive severance and change in control plan, or Severance Plan, for each of our executives with the title of vice president or above. Under the Severance Plan, if we terminate an executive other than for cause or if the executive resigns for good reason, each as defined in the Severance Plan, the executive will receive: (i) cash severance payments equal to 18 months of his or her annual base salary for our chief executive officer, 15 months for our other chief executives and 9 months for our senior vice presidents and vice presidents; (ii) a pro rata portion of his or her bonus based on actual achievement of applicable metrics for the year; (iii) payment of COBRA premiums for continued medical coverage for up to 18 months for our chief executive officer, 15 months for our other chief executives and 9 months for our senior vice presidents and vice presidents; and (iv) accelerated vesting on outstanding time-based stock options and restricted stock units that vest within 18 months for our chief executive officer, 15 months for our other chief executives and 9 months for our senior vice presidents and vice presidents (any performance-based equity awards will only be accelerated by the terms of such awards).

In the event an executive’s employment terminates without cause or the executive resigns for good reason and such termination occurs on or within 18 months following a Change in Control, as defined in the Severance Plan, he or she will receive: (i) cash severance payments equal to 18 months of his or her annual base salary for our chief executive officer, 15 months for our other chief executives and 9 months for our senior vice presidents and vice presidents; (ii) a pro rata portion of his or her target bonus for the year; (iii) cash severance payments equal to his or her target bonus for the year multiplied by 1.5 for our chief executive officer, 1.25 for our other chief executives and 0.75 for our senior vice presidents and vice presidents; (iv) payment of COBRA premiums for continued medical coverage for up to 18 months for our chief executive officer, 15 months for our other chief executives and 9 months for our senior vice presidents and vice presidents; and (v) full accelerated vesting on all outstanding stock options and restricted stock units (any performance-based equity awards will only be accelerated by the terms of such awards).

As a condition to receiving these severance benefits, the executive is required to execute a release of claims agreement in favor of us. The Severance Plan continues in effect for three years and shall automatically renew thereafter, unless we give notice of non-renewal prior to such renewal date. Although we have the right to amend or terminate the Severance Plan, we may not do so in any manner that diminishes any benefits being paid to an executive at the time of such amendment or termination.

Employment Agreements

As of December 31, 2020, we were party to employment agreements with certain senior management personnel, including our named executive officers. Each of these agreements provided for at-will employment and includes each officer’s base salary, a discretionary annual incentive bonus opportunity that may be based on individual and company performance and standard employee benefit plan participation. These agreements also provided for severance benefits upon termination of employment or a change in control of our company.  These agreements have been superseded by the Severance Plan.

Mr. Newell’s Employment Offer Letter

Mr. Newell is party to an offer letter with us dated December 29, 2008 pursuant to which he serves as our Chief Executive Officer. The terms and conditions of his offer letter provide for an annual base salary, and eligibility for an annual bonus, health insurance and other benefits, all subject to adjustment from time to time. Mr. Newell is an at-will employee.

On January 28, 2009, we entered into a Management Continuity Agreement with Mr. Newell, subsequently amended on September 27, 2016, which entitles Mr. Newell to certain severance benefits.

Upon a Change of Control (as defined in the Management Continuity Agreement) and subject to Mr. Newell’s execution of a release of claims in a form satisfactory to us, he would have been entitled to (i) 18 months of his then current annual base salary and (ii) 100% accelerated vesting on all outstanding Company stock options and restricted stock. Additionally, Mr. Newell would have been entitled to 100% paid premiums for his continued health benefits under COBRA for 18 months if we terminated his employment without Cause (as defined in the Management Continuity Agreement) or Mr. Newell voluntarily terminated his employment for Good Reason (as defined in the Management Continuity Agreement) following such Change of Control.

Absent a Change of Control, if we terminated Mr. Newell’s employment without Cause (as defined in the Management Continuity Agreement), or Mr. Newell voluntarily terminated his employment for Good Reason (as defined in the Management Continuity Agreement), and subject to his execution of a separation agreement and release of claims in a form satisfactory to us, he would have been entitled to (i) 18 months of his annual base salary, (ii) 18 months of accelerated vesting on all outstanding Company stock options and restricted stock and (iii) 100% paid premiums for his continued health benefits under COBRA for 18 months.  

22


Ms. Fitzpatrick’s Employment Offer Letter

Ms. Fitzpatrick is party to an offer letter with us dated August 8, 2018 pursuant to which she serves as our Chief People and Communications Officer. The terms and conditions of her offer letter provide for an annual base salary and eligibility for an annual bonus, health insurance and other benefits, all subject to adjustment from time to time. Ms. Fitzpatrick is an at-will employee.

Absent a Change of Control, if we terminated Ms. Fitzpatrick’s employment due to an Involuntary Termination (as defined in her offer letter), subject to Ms. Fitzpatrick’s execution of a separation agreement and release of claims in a form satisfactory to us, she would have been entitled to (i) 12 months of her then current annual base salary, (ii) 12 months of accelerated vesting on all outstanding stock options, (iii) payment of a pro rata portion of Ms. Fitzpatrick’s annual bonus (less applicable tax withholdings) and (iv) reimbursement for paid premiums for her continued health benefits under COBRA for 12 months.

If we terminated Ms. Fitzpatrick’s employment due to an Involuntary Termination (as defined in her offer letter) and such termination occurred on or within 12 months following a Change of Control (as defined in her offer letter), subject to Ms. Fitzpatrick’s execution of a separation agreement and release of claims in a form satisfactory to us, she would have been entitled to 100% accelerated vesting on all outstanding stock options.

Dr. Hallam’s Employment Offer Letter

Dr. Hallam is party to an offer letter with us dated November 12, 2010 pursuant to which he serves as our Chief Scientific Officer. The terms and conditions of his offer letter provide for an annual base salary and eligibility for an annual bonus, health insurance and other benefits, all subject to adjustment from time to time. Dr. Hallam is an at-will employee.

On September 27, 2016, we entered into an amendment with Dr. Hallam to amend certain severance provisions of his offer letter.

Absent a Change of Control (as defined in his amended offer letter), if we terminated Dr. Hallam’s employment without Cause or he resigned for Good Reason (each as defined in his amended offer letter), subject to Dr. Hallam’s execution of a separation agreement and release of claims in a form satisfactory to us, he would have been entitled to (i) 12 months of his then current annual base salary, (ii) 12 months of accelerated vesting on all outstanding stock options and restricted stock and (iii) reimbursement for paid premiums for his continued health benefits under COBRA for 12 months.

If we terminated Dr. Hallam’s employment without Cause or he resigns for Good Reason (each as defined in his amended offer letter) and such termination occurred on or within 12 months following a Change of Control (as defined in his amended offer letter), subject to Dr. Hallam’s execution of a separation agreement and release of claims in a form satisfactory to us, he would have been entitled to (i) 12 months of his then current annual base salary, (ii) 100% accelerated vesting on all outstanding stock options and restricted stock and (iii) reimbursement for paid premiums for his continued health benefits under COBRA for 12 months.

(3)

Any shares of common stock that are subject to outstanding awards under the 2004 Plan that are issuable upon the exercise of stock options that expire or become unexercisable for any reason without having been exercised in full will generally become available for future grant and issuance under our 2018 EIP. In addition, this includes 1,710,824 shares of common stock that remain available for grant under our 2018 EIP and 361,539 shares of common stock that remain available for purchase under the 2018 ESPP. Additionally, the number of shares reserved for issuance under our 2018 EIP will increase automatically on January 1 of each of 2019 through 2028 by the number of shares equal to the lesser of 5% of the aggregate number of outstanding shares of our common stock as of the immediately preceding December 31, or a number as may be determined by our Board of Directors. Pursuant to this provision, the number of shares reserved for grant and issuance under our 2018 EIP increased by 2,287,605, 1,154,948, and 1,142,409 shares, respectively, on January 1, 2021, 2020 and 2019. Similarly, the number of shares reserved for issuance under our 2018 ESPP will increase automatically on January 1 of each of 2019 through 2028 by the number of shares equal to the lesser of 1% of the aggregate number of outstanding shares of our common stock as of the immediately preceding December 31, or a number of shares as may be determined by our Board of Directors. Pursuant to this provision, the number of shares reserved for grant and issuance under our 2018 ESPP increased by 457,521, 230,989 and 228,481 shares, respectively, on January 1, 2021, 2020 and 2019.

CERTAIN RELATIONSHIPS AND RELATED-PARTY TRANSACTIONS

From January 1, 2020 to the present, there have been no transactions, and there are currently no proposed transactions, in which the amount involved exceeds $120,000 to which we or any of our subsidiaries was (or is to be) a party and in which any director, director nominee, executive officer, holder of more than 5% of our capital stock, or any immediate family member of or person sharing the household with any of these individuals, had (or will have) a direct or indirect material interest, except for payments set forth under “Proposal No. 1 Election of Class III Directors” and “Executive Compensation” above.

Policies and Procedures for Related-Person Transactions

 

Our Board of Directors has adopted a written related-person transactions policy. Under this policy, our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of our common stock, and any members of the immediate family of and any entity affiliated with any of the foregoing persons, are not permitted to enter into a material related person transaction with us without the review and approval of our audit committee, or a committee composed solely of independent directors in the event it is inappropriate for our audit committee to review such transaction due to a conflict of interest. The policy provides that any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of our common stock or with any of their immediate family members or affiliates in which the amount involved exceeds $120,000 will be presented to our audit committee for review, consideration and approval. In approving or rejecting any such proposal, our audit committee will consider the relevant facts and circumstances available and deemed relevant to the audit committee, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

ADDITIONAL INFORMATION

Stockholder Proposals to be Presented at Next Annual Meeting

Requirements for Stockholder Proposals to be Brought Before an Annual Meeting. Our bylaws provide that for stockholder nominations to our Board of Directors or other proposals to be considered at an annual meeting of stockholders, the stockholder must give timely notice thereof in writing to the Corporate Secretary at Sutro Biopharma, Inc., 310 Utah Avenue, Suite 150, South San Francisco, California, 94080.

A stockholder’s notice to the Corporate Secretary must set forth as to each matter the stockholder proposes to bring before the 2022 Annual Meeting the information required by applicable law and our bylaws. However, if the date of the 2022 Annual Meeting is more than 30 days before or more than 70 days after the one-year anniversary of the date of our 2021 Annual Meeting, for the stockholder notice to be timely, it must be delivered to the Corporate Secretary at our principal executive offices not earlier than the close of business on the 120th day prior to the currently proposed annual meeting and not later than the close of business on the later of (1) the 90th day prior to such annual meeting or (2) the close of business on the 10th day following the day on which public announcement of the date of such meeting is first made by us.

Available Information

The Annual Report on Form 10-K is also available at https://ir.sutrobio.com/.

“Householding” – Stockholders Sharing the Same Address

The SEC has adopted rules that permit companies and intermediaries (such as brokers) to implement a delivery procedure called “householding.” Under this procedure, multiple stockholders who reside at the same address may receive a single copy of our Annual Report on Form 10-K and proxy materials, unless the affected stockholder has provided other instructions. This procedure reduces printing costs and postage fees, and helps protect the environment as well.

 

We expect that a number of brokers with account holders who are our stockholders will be “householding” our Annual Report on Form 10-K and proxy materials. A single set of our Annual Report on Form 10-K and other proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from one or more of the affected stockholders. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. Stockholders may revoke their consent at any time by contacting their broker. Stockholders may revoke their consent at any time by contacting American Stock Transfer & Trust Company, LLC, either by calling toll-free (800) 937-5449, or by writing to American Stock Transfer & Trust Company, LLC, Operations Center, 6201 15th Avenue, Brooklyn, New York 11219.

Upon written or oral request, we will undertake to promptly deliver a separate copy of the proxy statement, proxy card, Annual Report on Form 10-K and other proxy materials to any stockholder at a shared address to which a single copy of any of those documents was delivered. To receive a separate copy of the proxy statement, proxy card, Annual Report on Form 10-K and other proxy materials, you may write our Investor Relations Department at Sutro Biopharma, Inc., 310 Utah Avenue, Suite 150, South San Francisco, California, 94080, Attn: Investor Relations, or call Annie Chang, Head of Investor Relations, at (650) 801-5728.  

Any stockholders who share the same address and currently receive multiple copies of our Annual Report on Form 10-K and other proxy materials who wish to receive only one copy in the future can contact their bank, broker or other holder of record to request information about “householding” or our Investor Relations Department at the address or telephone number listed above.
