FOR 2024 ANNUAL MEETING OF STOCKHOLDERS

To be held at 9:30 a.m., Pacific Time, on Tuesday, June 18, 2024

The information provided in the “question and answer” format below is for your convenience only and is merely a summary of the information contained in this proxy statement. You should read this entire proxy statement carefully before voting your shares.

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND OUR ANNUAL MEETING

Why am I receiving these materials?

This proxy statement and the form of proxy are furnished in connection with the solicitation of proxies by our board of directors for use at the 2024 Annual Meeting of stockholders of Viracta Therapeutics, Inc., a Delaware corporation, and any postponements, adjournments or continuations thereof. The Annual Meeting will be held on Tuesday, June 18, 2024, at 9:30 a.m., Pacific Time. The Annual Meeting will be conducted virtually via live audio webcast. You will be able to attend the Annual Meeting virtually by visiting https://www.proxydocs.com/VIRX, where you will be able to listen to the meeting live, submit questions and vote online during the meeting by entering the control number on your proxy card. If you have difficulty accessing the virtual meeting during the check-in or meeting time, a technical assistance phone number will be made available on the virtual meeting registration page 15 minutes prior to the start time of the meeting.

The Notice of Internet Availability of Proxy Materials, or Notice of Internet Availability, containing instructions on how to access this proxy statement, the accompanying notice of annual meeting and form of proxy, and our annual report, is first being sent or given on or about April 26, 2024, to all stockholders of record as of April 22, 2024. The proxy materials and our annual report can be accessed as of April 26, 2024, by visiting https://www.proxydocs.com/VIRX. If you receive a Notice of Internet Availability, then you will not receive a printed copy of the proxy materials or our annual report in the mail unless you specifically request these materials. Instructions for requesting a printed copy of the proxy materials and our annual report are set forth in the Notice of Internet Availability.

What proposals will be voted on at the Annual Meeting?

The following proposals will be voted on at the Annual Meeting:

•

the election of four (4) Class III directors to hold office until our 2027 annual meeting of stockholders and until their respective successors are elected and qualified;

•

to approve, on an advisory basis, the compensation of our named executive officers; and

•

the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024.

As of the date of this proxy statement, our management and board of directors were not aware of any other matters to be presented at the Annual Meeting.

How does the board of directors recommend that I vote on these proposals?

Our board of directors recommends that you vote your shares:

•

“FOR” the election of each Class III director nominee named in this proxy statement;

•

“FOR” the approval, on an advisory basis, of the compensation of our named executive officers; and

•

“FOR” the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024.

Who is entitled to vote at the Annual Meeting?

Holders of our common stock as of the close of business on April 22, 2024, the record date for the Annual Meeting, may vote at the Annual Meeting. As of the record date, there were 39,272,434 shares of our common stock outstanding. Each share of common stock is entitled to one vote on each matter properly brought before the Annual Meeting. Stockholders are not permitted to cumulate votes with respect to the election of directors.

Stockholders of Record. If your shares are registered directly in your name with our transfer agent, Equiniti Trust Company, LLC, then you are considered the stockholder of record with respect to those shares, and the Notice of Internet Availability sent directly to you by us. As a stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or to vote on your own behalf at the Annual Meeting. Throughout this proxy statement, we refer to these holders as “stockholders of record.”

Street Name Stockholders. If your shares are held in a brokerage account or by a broker, bank or other nominee, then you are considered the beneficial owner of shares held in street name, and the Notice of Internet Availability was forwarded to you by your broker, bank or other nominee, which is considered the stockholder of record with respect to those shares. As a beneficial owner, you have the right to direct your broker, bank or other nominee on how to vote the shares held in your account by following the instructions that your broker, bank or other nominee sent to you. Throughout this proxy statement, we refer to these holders as “street name stockholders.”

How many votes are needed for approval of each proposal?

•

Proposal No. 1: Each director is elected by a plurality of the voting power of the shares present in person (including virtually) or represented by proxy at the Annual Meeting and entitled to vote on the election of directors. A plurality means that the nominees with the largest number of FOR votes are elected as directors. You may (1) vote FOR the election of all of the director nominees named herein, (2) WITHHOLD authority to vote for all such director nominees or (3) vote FOR the election of all such director nominees other than any nominees with respect to whom the vote is specifically WITHHELD by indicating in the space provided on the proxy. Because the outcome of this proposal will be determined by a plurality vote, any shares not voted FOR a particular nominee, whether as a result of choosing to WITHHOLD authority to vote or a broker non-vote, will have no effect on the outcome of the election.

•

Proposal No. 2: The approval, on an advisory basis, of the compensation of our named executive officers requires the affirmative vote of a majority of the voting power of the shares present in person (including virtually) or represented by proxy at the Annual Meeting and entitled to vote thereon. You may vote FOR or AGAINST this proposal, or you may indicate that you wish to ABSTAIN from voting on this proposal. Abstentions will be counted for purposes of determining the presence or absence of a quorum. However, abstentions are not considered votes cast for or against a proposal, and thus will have no effect on the outcome of the vote on this proposal. Broker non-votes will also be counted for purposes of determining the presence or absence of a quorum but will have no effect on the outcome of this proposal. Because this proposal is an advisory vote, the result will not be binding on our board of directors or our company. Our board of directors and our compensation committee will consider the outcome of the vote when determining named executive officer compensation.

•

Proposal No. 3: The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024, requires the affirmative vote of a majority of the voting power of the shares present in person (including virtually) or represented by proxy at the Annual Meeting and entitled to vote thereon. You may vote FOR or AGAINST this proposal, or you may indicate that you wish to ABSTAIN from voting on this proposal. Abstentions will be counted for purposes of determining the presence or absence of a quorum. However, abstentions are not considered votes cast for or against a proposal, and thus will have no effect on the outcome of the vote on this proposal. Because this is a routine proposal, we do not expect any broker non-votes on this proposal.

-2-

What is the quorum requirement for the Annual Meeting?

A quorum is the minimum number of shares required to be present or represented at the Annual Meeting for the meeting to be properly held under our amended and restated bylaws and Delaware law. The presence, in person (including virtually) or by proxy, of a majority of the voting power of our capital stock issued and outstanding and entitled to vote will constitute a quorum to transact business at the Annual Meeting. Abstentions, choosing to withhold authority to vote and broker non-votes are counted as present and entitled to vote for purposes of determining a quorum. If there is no quorum, the chairperson of the meeting may adjourn the meeting to another time or place.

How do I vote and what are the voting deadlines?

Stockholder of Record. If you are a stockholder of record, you may vote in one of the following ways:

•

by Internet at https://www.proxydocs.com/VIRX 24 hours a day, 7 days a week, until 9:30 a.m., Pacific Time, on June 18, 2024 (have your Notice of Internet Availability or proxy card in hand when you visit the website);

•

by toll-free telephone at 1-866-458-1594, 24 hours a day, 7 days a week, until 9:30 a.m., Pacific Time, on June 18, 2024 (have your Notice of Internet Availability or proxy card in hand when you call);

•

by completing, signing and mailing your proxy card (if you received printed proxy materials), which must be received prior to the Annual Meeting; or

•

by attending the Annual Meeting virtually by visiting https://www.proxydocs.com/VIRX where you may vote during the meeting (have your Notice of Internet Availability or proxy card in hand when you visit the website).

Street Name Stockholders. If you are a street name stockholder, then you will receive voting instructions from your broker, bank or other nominee. The availability of Internet and telephone voting options will depend on the voting process of your broker, bank or other nominee. We therefore recommend that you follow the voting instructions in the materials you receive. If your voting instruction form or notice of internet availability of proxy materials indicates that you may vote your shares through the proxyvote.com website, then you may vote those shares at the Annual Meeting with the control number indicated on that voting instruction form or notice of internet availability of proxy materials. Otherwise, you may not vote your shares at the Annual Meeting unless you obtain a legal proxy from your broker, bank or other nominee.

What if I do not specify how my shares are to be voted or fail to provide timely directions to my broker, bank or other nominee?

Stockholder of Record. If you are a stockholder of record and you submit a proxy, but you do not provide voting instructions, your shares will be voted:

•

“FOR” the election of each Class III director nominee named in this proxy statement;

•

“FOR” the approval, on an advisory basis, of the compensation of our named executive officers; and

•

“FOR” the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024.

In addition, if any other matters are properly brought before the Annual Meeting, the persons named as proxies will be authorized to vote or otherwise act on those matters in accordance with their judgment.

Street Name Stockholders. Brokers, banks and other nominees holding shares of common stock in street name for customers are generally required to vote such shares in the manner directed by their customers. In the absence of timely directions, your broker, bank or other nominee will have discretion to vote your shares on our sole routine matter: the proposal to ratify the appointment of Ernst & Young LLP as our independent registered public

-3-

accounting firm for our fiscal year ending December 31, 2024. Your broker, bank or other nominee will not have discretion to vote on any other proposals, which are considered non-routine matters, absent direction from you. In the event that your broker, bank or other nominee votes your shares on our sole routine matter, but is not able to vote your shares on the non-routine matters, then those shares will be treated as broker non-votes with respect to the non-routine proposals. Accordingly, if you own shares through a nominee, such as a broker or bank, please be sure to instruct your nominee how to vote to ensure that your shares are counted on each of the proposals.

Can I change my vote or revoke my proxy?

Stockholder of Record. If you are a stockholder of record, you can change your vote or revoke your proxy before (or at) the Annual Meeting by:

•

entering a new vote by Internet or telephone (subject to the applicable deadlines for each method as set forth above);

•

completing and returning a later-dated proxy card, which must be received prior to the Annual Meeting;

•

delivering a written notice of revocation to our corporate secretary at Viracta Therapeutics, Inc., 2533 S. Coast Hwy. 101, Suite 210, Cardiff, California 92007, Attention: Corporate Secretary, which must be received prior to the Annual Meeting; or

•

attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not, by itself, revoke a proxy).

Street Name Stockholders. If you are a street name stockholder, then your broker, bank or other nominee can provide you with instructions on how to change or revoke your proxy.

What do I need to do to attend the Annual Meeting?

We will be hosting the Annual Meeting via live audio webcast only.

Stockholder of Record. If you were a stockholder of record as of the record date, then you may attend the Annual Meeting virtually, and will be able to submit your questions during the meeting and vote your shares electronically during the meeting by visiting https://www.proxydocs.com/VIRX. To attend and participate in the Annual Meeting, you will need the control number included on your Notice of Internet Availability or proxy card. The Annual Meeting live audio webcast will begin promptly at 9:30 a.m., Pacific Time. We encourage you to access the meeting prior to the start time. Online check-in will begin fifteen minutes prior to the meeting, and you should allow ample time for the check-in procedures.

Street Name Stockholders. If you were a street name stockholder as of the record date and your voting instruction form or notice of internet availability of proxy materials indicates that you may vote your shares through the proxyvote.com website, then you may access and participate in the Annual Meeting with the control number indicated on that voting instruction form or notice of internet availability of proxy materials. Otherwise, street name stockholders should contact their bank, broker or other nominee and obtain a legal proxy in order to be able to attend and participate in the Annual Meeting.

How can I get help if I have trouble checking in or listening to the Annual Meeting online?

If you encounter difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the virtual meeting log-in page.

-4-

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of our board of directors. Mark Rothera, our President and Chief Executive Officer and Melody Burcar, our Senior Vice President, Finance, have been designated as proxy holders for the Annual Meeting by our board of directors. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the Annual Meeting in accordance with the instructions of the stockholder. If the proxy is dated and signed, but no specific instructions are given, however, the shares will be voted in accordance with the recommendations of our board of directors on the proposals as described above. If any other matters are properly brought before the Annual Meeting, then the proxy holders will use their own judgment to determine how to vote your shares. If the Annual Meeting is postponed or adjourned, then the proxy holders can vote your shares on the new meeting date, unless you have properly revoked your proxy, as described above.

How can I contact Viracta’s transfer agent?

You may contact our transfer agent, Equiniti Trust Company, LLC, by telephone at (800) 937-5449, or by writing Equiniti Trust Company, LLC, at 6201 15^th Avenue, Brooklyn, NY 11219. You may also access instructions with respect to certain stockholder matters (e.g., change of address) via the Internet at https://equiniti.com/us/.

How are proxies solicited for the Annual Meeting and who is paying for such solicitation?

Our board of directors is soliciting proxies for use at the Annual Meeting by means of the proxy materials. We will bear the entire cost of proxy solicitation, including the preparation, assembly, printing, mailing and distribution of the proxy materials. Copies of solicitation materials will also be made available upon request to brokers, banks and other nominees to forward to the beneficial owners of the shares held of record by such brokers, banks or other nominees. The original solicitation of proxies may be supplemented by solicitation by telephone, electronic communications or other means by our directors, officers or employees. No additional compensation will be paid to these individuals for any such services, although we may reimburse such individuals for their reasonable out-of-pocket expenses in connection with such solicitation.

Where can I find the voting results of the Annual Meeting?

We will disclose voting results on a Current Report on Form 8-K that we will file with the U.S. Securities and Exchange Commission, or SEC, within four business days after the meeting. If final voting results are not available to us in time to file a Form 8-K, we will file a Form 8-K to publish preliminary results and will provide the final results in an amendment to the Form 8-K as soon as they become available.

Why did I receive a Notice of Internet Availability instead of a full set of proxy materials?

In accordance with the rules of the SEC we have elected to furnish our proxy materials, including this proxy statement and our annual report, primarily via the Internet. As a result, we are mailing to our stockholders a Notice of Internet Availability instead of a paper copy of the proxy materials. The Notice of Internet Availability contains instructions on how to access our proxy materials on the Internet, how to vote on the proposals, how to request printed copies of the proxy materials and our annual report, and how to request to receive all future proxy materials in printed form by mail or electronically by e-mail. We encourage stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce our costs and the environmental impact of our annual meetings.

-5-

What does it mean if I receive more than one Notice of Internet Availability or more than set of printed proxy materials?

If you receive more than one Notice of Internet Availability or more than one set of printed proxy materials, then your shares may be registered in more than one name and/or are registered in different accounts. Please follow the voting instructions on each Notice of Internet Availability or each set of printed proxy materials, as applicable, to ensure that all of your shares are voted.

I share an address with another stockholder, and we received only one paper copy of the Notice of Internet Availability or proxy statement and annual report. How may I obtain an additional copy of the Notice of Internet Availability or proxy statement and annual report?

We have adopted a procedure approved by the SEC called “householding,” under which we can deliver a single copy of the Notice of Internet Availability and, if applicable, the proxy statement and annual report, to multiple stockholders who share the same address unless we receive contrary instructions from one or more stockholders. This procedure reduces our printing and mailing costs. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, we will deliver promptly a separate copy of the Notice of Internet Availability and, if applicable, the proxy statement and annual report, to any stockholder at a shared address to which we delivered a single copy of these documents. To receive a separate copy, or, if you are receiving multiple copies, to request that we only send a single copy of next year’s Notice of Internet Availability or proxy statement and annual report, as applicable, you may contact us as follows:

Viracta Therapeutics, Inc.

Attention: Investor Relations

2533 S. Coast Hwy. 101, Suite 210

Cardiff, California 92007

Tel: (858) 400-8470

Street name stockholders may contact their broker, bank or other nominee to request information about householding.

What is the deadline to propose actions for consideration at next year’s annual meeting of stockholders or to nominate individuals to serve as directors?

If a stockholder would like us to consider including a proposal in our proxy statement for our 2025 annual meeting pursuant to Rule 14a-8 of the Exchange Act, then the proposal must be received by our corporate secretary at our principal executive offices on or before December 27, 2024. In addition, stockholder proposals must comply with the requirements of Rule 14a-8 and Rule 14a-19 under the Exchange Act regarding the inclusion of stockholder proposals in company-sponsored proxy materials. Proposals should be addressed to:

Viracta Therapeutics, Inc.

Attention: Corporate Secretary

2533 S. Coast Hwy. 101, Suite 210

Cardiff, California 92007

Our amended and restated bylaws also establish an advance notice procedure for stockholders who wish to present a proposal or nominate a director at an annual meeting, but do not seek to include the proposal or director nominee in our proxy statement. In order to be properly brought before our 2025 annual meeting, the stockholder must provide timely written notice to our corporate secretary, at our principal executive offices, and any such proposal or nomination must constitute a proper matter for stockholder action. The written notice must contain the information specified in our amended and restated bylaws. To be timely, a stockholder’s written notice must be received by our corporate secretary at our principal executive offices no later than December 27, 2024.

-6-

In the event that we hold our 2025 annual meeting more than 30 days before or after the one-year anniversary of this year’s Annual Meeting, then such written notice must be received by our corporate secretary at our principal executive offices:

•

no earlier than the 120th day prior to the day of our 2025 annual meeting, and

•

no later than the 10th day following the day on which public announcement of the date of the annual meeting is first made by us.

If a stockholder who has notified us of his, her or its intention to present a proposal at an annual meeting of stockholders does not appear to present his, her or its proposal at such annual meeting, then we are not required to present the proposal for a vote at such annual meeting.

Availability of Bylaws

A copy of our amended and restated bylaws may be obtained by accessing our filings on the SEC’s website at www.sec.gov. You may also contact our corporate secretary at our principal executive offices for a copy of the relevant bylaw provisions regarding the requirements for making stockholder proposals and nominating director candidates.

Nominees for Director

Flavia Borellini, Ph.D., Director

Dr. Borellini has served as a member of the board of directors since August 2021. Dr. Borellini has more than 25 years of executive management experience in the pharmaceutical and biotechnology industry, with a particular focus on global development of targeted oncology drugs, from preclinical to commercial stage. She is the former Chief Executive Officer for Acerta Pharma, where she oversaw the successful development and approval of Calquence^® (acalabrutinib), a selective Bruton’s tyrosine kinase (BTK) inhibitor, for the treatment of mantle cell lymphoma and chronic lymphocytic leukemia (CLL). During her career, Dr. Borellini has also held key senior level positions within AstraZeneca, most recently Global Franchise Head, Hematology, with responsibility for the hematology portfolio in the company’s oncology business unit. While at AstraZeneca, she led the global development, approval, and commercialization of Tagrisso^® (osimertinib), a first-in-class epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor for the treatment of non-small cell lung cancer (NSCLC) caused by the T790M mutation. Prior to her tenure with AstraZeneca, Dr. Borellini spent nearly seven years at Genentech, a member of the Roche Group. During this time, she led the global development, approval and launch of Zelboraf^® (vemurafenib), a first-in-class BRAF inhibitor for the treatment of melanoma caused by the V600E BRAF mutation. Dr. Borellini also served as the program leader for Herceptin^® (trastuzumab), a targeted treatment for HER2 receptor positive cancers, including breast cancer, and Tarceva^® (erlotinib), an

-8-

EGFR tyrosine kinase inhibitor for the treatment of NSCLC and pancreatic cancer. Dr. Borellini also serves on the Board of Directors of Kartos Therapeutics, Cantargia AP, and Revolution Medicines (NASDAQ: RVMD). Dr. Borellini obtained a Ph.D. in Pharmaceutical Chemistry and Technology from the University of Modena in 1984.

We believe Dr. Borellini is qualified to serve on our board of directors because of her management experience in the pharmaceutical and biotechnology industry.

Jane Chung, R.Ph., Director

Ms. Chung has served as a member of the board of directors since August 2022.

Director Independence

Our common stock is listed on Nasdaq. As a company listed on Nasdaq, we are required under Nasdaq listing rules to maintain a board comprised of a majority of independent directors as determined affirmatively by our board. Under Nasdaq listing rules, a director will only qualify as an independent director if, in the opinion of that listed company’s board of directors, the director does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In addition, the Nasdaq listing rules require that, subject to specified exceptions, each member of our audit, compensation and nominating and corporate governance committees be independent.

-12-

Audit committee members must also satisfy the additional independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and Nasdaq listing rules applicable to audit committee members. Compensation committee members must also satisfy the additional independence criteria set forth in Rule 10C-1 under the Exchange Act and Nasdaq listing rules applicable to compensation committee members.

Our board of directors has undertaken a review of the independence of each of our directors. Based on information provided by each director concerning his or her background, employment and affiliations, our board of directors has determined that Dr. Barlow, Dr. Borellini, Ms. Chung, Mr. Darcy, Dr. Murphy, Dr. Pomerantz, Dr. Rubino and Dr. Simon, representing eight (8) of our ten (10) directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is an “independent director” as defined under the listing standards of Nasdaq. Mark Rothera is not considered an independent director because of his position as our chief executive officer and Ivor Royston is not considered an independent director because of his former position as our chief executive officer.

In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances that our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them described in the section titled “Related Person Transactions.”

There are no family relationships among any of our directors, director nominees or executive officers.

Board Leadership Structure

Our corporate governance framework provides our board flexibility to determine the appropriate leadership structure for the company, and whether the roles of chairperson and chief executive officer should be separated or combined. In making this determination, our board considers many factors, including the needs of the business, our board’s assessment of its leadership needs from time to time and the best interests of our stockholders. If the role of chairperson is filled by a director who does not qualify as an independent director, then our corporate governance guidelines provide that one of our independent directors may serve as our lead independent director.

Our board believes that it is currently appropriate to separate the roles of chairperson and chief executive officer. The chief executive officer is responsible for day-to-day leadership, while our chairperson, along with the rest of our independent directors, ensures that our board’s time and attention is focused on providing independent oversight of management and matters critical to our company. The board believes that Dr. Pomerantz’s deep knowledge of the company and industry, as well as strong leadership and governance experience, enable Dr. Pomerantz to lead our board effectively and independently.

Role of Board in Risk Oversight Process

Risk is inherent with every business, and we face a number of risks, including strategic, financial, business and operational, legal and compliance and reputational. We have designed and implemented processes to manage risk in our operations. Management is responsible for the day-to-day management of risks the company faces, while our board of directors, as a whole and assisted by its committees, has responsibility for the oversight of risk management. Our board reviews strategic and operational risk in the context of discussions, question and answer sessions, and reports from the management team at each regular board meeting, receives reports on all significant committee activities at each regular board meeting, and evaluates the risks inherent in significant transactions.

In addition, our board has tasked designated standing committees with oversight of certain categories of risk management. Our audit committee assists our board in fulfilling its oversight responsibilities with respect to risk

-13-

management in the areas of internal control over financial reporting and disclosure controls and procedures, legal and regulatory compliance, and also, among other things, discusses with management and the independent auditor guidelines and policies with respect to risk assessment and risk management. Our compensation committee assesses risks relating to our executive compensation plans and arrangements, and whether our compensation policies and programs have the potential to encourage excessive risk taking. Our nominating and corporate governance committee assesses risks relating to our corporate governance practices, the independence of the board and potential conflicts of interest.

Our board of directors believes its current leadership structure supports the risk oversight function of the board.

Considerations in Evaluating Director Nominees

Our nominating and corporate governance committee uses a variety of methods for identifying and evaluating potential director nominees. In its evaluation of director candidates, including the current directors eligible for re-election, our nominating and corporate governance committee will consider the current size and composition of our board of directors and the needs of our board of directors and the respective committees of our board of directors and other director qualifications. While our board has not established minimum qualifications for board members, some of the factors that our nominating and corporate governance committee considers in assessing director nominee qualifications include, without limitation, issues of character, professional ethics and integrity,

-17-

judgment, business experience and diversity, and with respect to diversity, such factors as race, ethnicity, gender, differences in professional background, age and geography, as well as other individual qualities and attributes that contribute to the total mix of viewpoints and experience represented on our board. Although our board of directors does not maintain a specific policy with respect to board diversity, our board of directors believes that the board should be a diverse body, and the nominating and corporate governance committee considers a broad range of perspectives, backgrounds and experiences.

If our nominating and corporate governance committee determines that an additional or replacement director is required, then the committee may take such measures as it considers appropriate in connection with its evaluation of a director candidate, including candidate interviews, inquiry of the person or persons making the recommendation or nomination, engagement of an outside search firm to gather additional information, or reliance on the knowledge of the members of the committee, board or management.

After completing its review and evaluation of director candidates, our nominating and corporate governance committee recommends to our full board of directors the director nominees for selection. Our nominating and corporate governance committee has discretion to decide which individuals to recommend for nomination as directors and our board of directors has the final authority in determining the selection of director candidates for nomination to our board.

Stockholder Recommendations and Nominations to our Board of Directors

Our nominating and corporate governance committee will consider recommendations and nominations for candidates to our board of directors from stockholders in the same manner as candidates recommended to the committee from other sources, so long as such recommendations and nominations comply with our amended and restated certificate of incorporation and amended and restated bylaws, all applicable company policies and all applicable laws, rules and regulations, including those promulgated by the SEC. Our nominating and corporate governance committee will evaluate such recommendations in accordance with its charter, our bylaws and corporate governance guidelines and the director nominee criteria described above.

screen for communications that (1) are solicitations for products and services, (2) relate to matters of a personal nature not relevant for our stockholders to act on or for our board to consider and (3) matters that are of a type that are improper or irrelevant to the functioning of our board or our business, for example, mass mailings, job inquiries and business solicitations. If appropriate, our General Counsel will route such communications to the appropriate director(s) or, if none is specified, then to the chairperson of the board. These policies and procedures do not apply to communications to non-management directors from our officers or directors who are stockholders or stockholder proposals submitted pursuant to Rule 14a-8 under the Exchange Act.

Policy Prohibiting Hedging or Pledging of Securities

Under our insider trading policy, our employees, including our executive officers, and the members of our board of directors are prohibited from, directly or indirectly, among other things, (1) engaging in short sales, (2) trading in publicly-traded options, such as puts and calls, and other derivative securities with respect to our securities (other than stock options, restricted stock units and other compensatory awards issued to such individuals by us), (3) purchasing financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds), or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of equity securities granted to them by us as part of their compensation or held, directly or indirectly, by them, (4) pledging any of our securities as collateral for any loans and (5) holding our securities in a margin account.

Corporate Governance Guidelines and Code of Business Conduct and Ethics

Our board of directors has adopted corporate governance guidelines. These guidelines address, among other items, the qualifications and responsibilities of our directors and director candidates, the structure and composition of our board of directors and corporate governance policies and standards applicable to us in general. In addition, 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. The full text of our corporate governance guidelines and code of business conduct and ethics are available on our investor relations website at https://viracta.investorroom.com. We will post amendments to our code of business conduct and ethics or any waivers of our code of business conduct and ethics for directors and executive officers on the same website.

Director Compensation

Under our non-employee director compensation policy, as amended and restated in August 2023, non-employee directors will receive compensation in the form of cash and equity, as described below. We also reimburse our non-employee directors for expenses incurred in connection with attending board and committee meetings as well as continuing director education. Our compensation committee has primary responsibility for reviewing and approving the compensation paid to non-employee directors. Our compensation committee reviews at least annually the type and form of compensation paid to our non-employee directors.

Cash Compensation

Under our non-employee director compensation policy, each non-employee director is paid an annual cash retainer of $40,000. In addition, each non-employee director is entitled to receive the following cash compensation for his or her services under the policy:

•

$20,000 per year for service as chair of the audit committee;

•

$10,000 per year for service as a member of the audit committee;

•

$15,000 per year for service as chair of the compensation committee;

•

$7,500 per year for service as a member of the compensation committee;

-19-

•

$7,500 per year for service as chair of the nominating and corporate governance committee;

•

$5,000 per year for service as a member of the nominating and corporate governance committee;

•

$7,500 per year for service as chair of the science and technology committee; and

•

$5,000 per year for service as a member of the science and technology committee.

Each non-employee director who serves as a committee chair receives only the additional annual cash fee as the chair of the committee, and not the additional annual fee as a member of the committee. All cash payments to non-employee directors are paid quarterly in arrears on a prorated basis. The above-listed fees for service as chair or members of committees are payable in addition to the non-employee director retainer.

Equity Compensation

Initial Options. Each person who first becomes a non-employee director after the effective date of the non-employee director compensation policy will receive, on the first trading day on or after the date that the person first becomes a non-employee director, an initial award (or, the “Initial Award”) of stock options to purchase 80,000 shares of our common stock. The Initial Award will be scheduled to vest in equal installments as to 1/36th of the shares of our common stock subject to the Initial Award on a monthly basis following the Initial Award’s grant date, on the same day of the month as the grant date, subject to continued services to us through the applicable vesting dates. If the person was a member of our board of directors and also an employee, then becoming a non-employee director due to termination of employment will not entitle the person to an Initial Award.

Annual Options. Each continuing non-employee director automatically will receive, on the date of each annual meeting of our stockholders, an annual award (or, the “Annual Award)” of stock options to purchase 40,000 shares of our common stock. Each Annual Award will be scheduled to vest as to 1/12th shares subject to the Annual Award on a monthly basis following the Annual Award’s grant date on the same day of the month as such grant date (or the last day of the month, if there is no corresponding day in such month), or if earlier, 100% of the shares subject to the Annual Award shall vest on the day immediately before the date of the next annual meeting that occurs after the Annual Award’s grant date, subject to continued services to us through the applicable vesting date.

Chair Award. On the first trading day immediately following each annual meeting, the non-employee director then serving as the chairperson of the board of directors automatically will receive an award of stock options to purchase a number of shares equal to thirty-seven and one-half percent (37.5%) of the number of shares subject to the Annual Award, rounded down to the nearest whole share (the “Chair Award”). The Chair Award will be scheduled to vest as to one-twelfth (1/12^th) of the shares subject to the Chair Award on a monthly basis following the Chair Award’s grant date on the same day of the month as such grant date (or on the last day of the month, if there is no corresponding day in such month), or if earlier, the day immediately before the date of the next Annual Meeting that occurs after the Chair Award’s grant date, subject to continued services to us through the applicable vesting date.

Change in Control. In the event of a change in control, as defined in our 2021 Equity Incentive Plan, each non-employee director’s then outstanding company equity awards covering shares of our common stock will accelerate vesting in full, provided that he or she remains a non-employee director through the date of our change in control.

Other Award Terms. Each Initial Award and Annual Award is granted under our 2021 Equity Incentive Plan (or its successor plan, as applicable) and form of award agreement under such plan. These awards have a maximum term to expiration of 10 years from their grant and a per share exercise price equal to 100% of the fair market value of a share of our common stock on the award’s grant date.

PROPOSAL NO. 1

ELECTION OF CLASS III DIRECTORS

Our board of directors currently consists of ten (10) directors and is divided into three classes with staggered three-year terms. At the Annual Meeting, four (4) Class III directors will be elected for a three-year term to succeed the same class whose term is then expiring. Each director’s term continues until the expiration of the term for which such director was elected and until such director’s successor is elected and qualified or until such director’s earlier death, resignation or removal.

Nominees

Our nominating and corporate governance committee has recommended, and our board of directors has approved, Flavia Borellini, Ph.D., Jane Chung, R.Ph., Ivor Royston, M.D., Stephen Rubino, Ph.D., M.B.A as nominees for election as Class III directors at the Annual Meeting. If elected, each will serve as a Class III director until the 2027 annual meeting of stockholders and until his or her respective successor is elected and qualified or until his or her earlier death, resignation or removal. For more information concerning the nominees, please see the section titled “Board of Directors and Corporate Governance.”

Dr. Borellini, Ms. Chung, Dr. Royston and Dr. Rubino have agreed to serve as directors if elected, and management has no reason to believe that they will be unavailable to serve. In the event a nominee is unable or declines to serve as a director at the time of the Annual Meeting, proxies will be voted for any nominee designated by the present board of directors to fill the vacancy.

Vote Required

Each director is elected by a plurality of the voting power of the shares present in person (including virtually) or represented by proxy at the meeting and entitled to vote on the election of directors. Because the outcome of this proposal will be determined by a plurality vote, any shares not voted FOR a particular nominee, whether as a result of choosing to WITHHOLD authority to vote or a broker non-vote, will have no effect on the outcome of the election.

Board Recommendation

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE ELECTION OF EACH OF THE DIRECTOR NOMINEES NAMED ABOVE.

-23-

PROPOSAL NO. 2

ADVISORY VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

At the 2019 annual meeting of stockholders, our board of directors recommended and the stockholders approved holding an advisory vote on the compensation of the company’s named executive officers every year, and we are maintaining the frequency of such vote. Accordingly, pursuant to Section 14A of the Exchange Act, we are asking our stockholders to approve, on an advisory or non-binding basis, the compensation of our named executive officers as described in this proxy statement. This proposal, commonly referred to as the “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our named executive officers’ compensation as a whole. This vote is not intended to address any specific item of compensation or any specific named executive officer, but rather the overall compensation of all of our named executive officers and the philosophy, policies and practices described in this proxy statement.

The say-on-pay vote is advisory, and therefore is not binding on us, our compensation committee or our board of directors. The say-on-pay vote will, however, provide information to us regarding investor sentiment about our executive compensation philosophy, policies and practices, which our compensation committee will be able to consider when determining executive compensation for the remainder of the current fiscal year and beyond. Our board of directors and our compensation committee value the opinions of our stockholders. To the extent there is any significant vote against the compensation of our named executive officers as disclosed in this proxy statement, we will endeavor to communicate with stockholders to better understand the concerns that influenced the vote and consider our stockholders’ concerns, and our compensation committee will evaluate whether any actions are necessary to address those concerns.

You are encouraged to review the section titled “Executive Compensation”, which provides an overview of our executive compensation program and contains tabular information and narrative discussion about the compensation of our named executive officers.

We are asking our stockholders to approve the compensation of our named executive officers as described in this proxy statement by voting for the following non-binding resolution:

“RESOLVED, that the stockholders approve, on an advisory basis, the compensation paid to our named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the compensation tables and the narrative discussion.”

Vote Required

The approval, on an advisory basis, of the compensation of our named executive officers requires the affirmative vote of a majority of the voting power of the shares present in person (including virtually) or represented by proxy at the Annual Meeting and entitled to vote thereon. Abstentions and broker non-votes will have no effect on the outcome of the vote on this proposal.

As an advisory vote, the result of this proposal is non-binding. Although the vote is non-binding, our board of directors and our compensation committee value the opinions of our stockholders and will consider the outcome of the vote when making future compensation decisions for our named executive officers.

Board Recommendation

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT.

Our audit committee has appointed Ernst & Young LLP as our independent registered public accounting firm to audit our consolidated financial statements for our fiscal year ending December 31, 2024. Ernst & Young LLP has served as our independent registered public accounting firm since 1998.

At the Annual Meeting, we are asking our stockholders to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024. Our audit committee is submitting the appointment 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. Notwithstanding the appointment of Ernst & Young LLP, and even if our stockholders ratify the appointment, our audit committee, in its discretion, may appoint another independent registered public accounting firm at any time during our fiscal year if our audit committee believes that such a change would be in the best interests of our company and our stockholders. If our stockholders do not ratify the appointment of Ernst & Young LLP, then our audit committee may reconsider the appointment. One or more representatives of Ernst & Young LLP are expected to be present at the Annual Meeting, and they will have an opportunity to make a statement and are expected to be available to respond to appropriate questions from our stockholders.

Fees Paid to the Independent Registered Public Accounting Firm

Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm

Our Audit Committee has established a policy governing our use of the services of our independent registered public accounting firm. Under the policy, our Audit Committee is required to pre-approve all audit and permissible non-audit services performed by our independent registered public accounting firm in order to ensure that the provision of such services does not impair such accounting firm’s independence. All fees paid to Ernst & Young LLP for our fiscal years ended December 31, 2023 and 2022 were pre-approved by our Audit Committee.

Vote Required

The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024, requires affirmative vote of a majority of the voting power of the shares present in person (including virtually) or represented by proxy at the Annual Meeting and entitled to vote thereon. Abstentions will have the same effect as a vote AGAINST this proposal.

Board Recommendation

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR OUR FISCAL YEAR ENDING DECEMBER 31, 2024.

REPORT OF THE AUDIT COMMITTEE

The audit committee is a committee of the board of directors comprised solely of independent directors as required by Nasdaq listing rules and the rules and regulations of the SEC. The audit committee operates under a written charter adopted by the board of directors. This written charter is reviewed annually for changes, as appropriate. With respect to Viracta’s financial reporting process, Viracta’s management is responsible for (1) establishing and maintaining internal controls and (2) preparing Viracta’s consolidated financial statements. Viracta’s independent registered public accounting firm, Ernst & Young LLP, is responsible for performing an independent audit of Viracta’s consolidated financial statements. It is the responsibility of the audit committee to oversee these activities. It is not the responsibility of the audit committee to prepare Viracta’s financial statements. These are the fundamental responsibilities of management. In the performance of its oversight function, the audit committee has:

•

reviewed and discussed the audited consolidated financial statements with management and Ernst & Young LLP;

•

discussed with Ernst & Young LLP the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board, or PCAOB, and the SEC; and

•

received the written disclosures and the letter from Ernst & Young LLP required by the applicable requirements of the PCAOB regarding the independent accountant’s communications with the audit committee concerning independence, and has discussed with Ernst & Young LLP its independence.

Based on the review and discussions noted above, the audit committee recommended to the board of directors that the audited consolidated financial statements be included Viracta’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for filing with the SEC.

Respectfully submitted by the members of the audit committee of the board of directors:

Thomas E. Darcy, CPA (Chair)

Stephen Rubino, Ph.D., MBA

Barry J. Simon, M.D.

This audit committee report shall not be deemed to be “soliciting material” or to be “filed” with the SEC or subject to Regulation 14A promulgated by the SEC or to the liabilities of Section 18 of the Exchange Act, and shall not be deemed incorporated by reference into any prior or subsequent filing by Viracta under the Securities Act of 1933, as amended, or the Securities Act, or the Exchange Act, except to the extent Viracta specifically requests that the information be treated as “soliciting material” or specifically incorporates it by reference.

EXECUTIVE COMPENSATION

Processes and Procedures for Compensation Decisions

Our compensation committee is responsible for the executive compensation programs for our executive officers and reports to our board of directors on its discussions, decisions and other actions. Typically, our Chief Executive Officer makes recommendations to our compensation committee, often attends committee meetings and is involved in the determination of compensation for the respective executive officers who report to him, except that the Chief Executive Officer does not make recommendations as to his own compensation. Our Chief Executive Officer makes recommendations to our compensation committee regarding short- and long-term compensation for all executive officers (other than himself) based on our results, an individual executive officer’s contribution toward these results and performance toward individual goal achievement. Our compensation committee then reviews the recommendations and other data. Our compensation committee makes decisions as to total compensation for each executive office, although it may instead, in its discretion, make recommendations to our board of directors regarding executive compensation for its approval.

Our compensation committee is authorized to retain the services of one or more executive compensation advisors, as it sees fit, in connection with the establishment of our compensation programs and related policies. In each of 2022 and 2023, our compensation committee retained Aon Radford, an independent compensation consultant, to provide it with information, recommendations and other advice relating to executive compensation on an ongoing basis. Aon Radford continues to serve at the discretion of our compensation committee. Our compensation committee engaged Aon Radford to assist in developing an appropriate group of peer companies to help us determine the appropriate level of overall compensation for our executive officers, as well as assess each separate element of compensation, with a goal of ensuring that the compensation we offer to our executive officers is competitive and fair.

Our named executive officers, consisting of our principal executive officer and the two most highly compensated executive officers (other than our principal executive officer), as of December 31, 2023, were:

•

Mark Rothera., our President, Chief Executive Officer, and Director;

•

Darrel Cohen, M.D., our Chief Medical Officer; and

•

Daniel Chevallard, our former Chief Financial Officer, Chief Operating Officer, Treasurer and Secretary.*

*	In March 2024, Daniel Chevallard resigned from his positions as an officer of the Company.

Non-Equity Incentive Plan Compensation

At the beginning of each of 2022 and 2023, we adopted a bonus plan for our executive and non-executive employees that provides for cash incentives for performance in the applicable year. Each of the 2022 and 2023 bonus opportunities for our executives was based on the assessment of our board of directors of the achievement of company objectives that were established by our board of directors or our compensation committee, as applicable, for the applicable year as well as other achievements which occurred during the year. The company objectives for each of 2022 and 2023 consisted primarily of clinical, pre-clinical and corporate development goals. Based on our performance against the approved company objectives and other operational milestones during the year, our board of directors or our compensation committee, as applicable, determined to fund the 2022 bonus plan at 85.0% of the target level and the 2023 bonus plan at 102.5% of the target level.

The amounts in the Summary Compensation Table under the column “Non-equity incentive plan compensation” are based on the named executive officer’s target bonus amount multiplied by the achievement percentage set by our board of directors or our compensation committee, as applicable, consistent with the determinations under the applicable year’s bonus plan (and further pro-rated based on the period of time during which they were employed with us during the year).

Executive Incentive Compensation Plan

Effective March 14, 2022, we adopted an Executive Incentive Compensation Plan (the “Incentive Compensation Plan”). Our Incentive Compensation Plan allows our compensation committee (or other committee designated by our board of directors) to grant incentive awards, generally payable in cash, to employees selected by our compensation committee, including our executive officers, based upon performance goals established by our compensation committee.

Under our Incentive Compensation Plan, our compensation committee determines the performance goals applicable to any award, which goals may include, without limitation, goals related to research and development, regulatory milestones or regulatory-related goals, financial milestones, new product or business development, other product release milestones, publications, cash flow, internal structure, leadership development, project, function or portfolio- specific milestones, license or research collaboration agreements, capital raising, patentability and individual objectives such as peer reviews or other subjective or objective criteria. The performance goals may differ from participant to participant and from award to award. For 2022 and 2023, the applicable performance goals for our named executive officers were certain product and corporate goals, as well as individual performance.

The compensation committee administers our Incentive Compensation Plan and may, in its sole discretion and at any time, increase, reduce or eliminate a participant’s actual award, and/or increase, reduce or eliminate the amount allocated to the bonus pool for a particular performance period. The actual award may be below, at or above a participant’s target award, in the discretion of the administrator. The administrator may determine the amount of any increase, reduction or elimination on the basis of such factors as it deems relevant, and it will not be required to establish any allocation or weighting with respect to the factors it considers.

Actual awards generally will be paid in cash (or its equivalent) only after they are earned, and, unless otherwise determined by the administrator, to earn an actual award a participant must be employed by us through the date the actual award is paid. The administrator of the Incentive Compensation Plan may reserve the right to settle an actual award with a grant of an equity award under our then-current equity compensation plan, which equity award may have such terms and conditions, including vesting, as the administrator determines. Payment of awards will occur as soon as practicable after they are earned, but no later than the dates set forth in our Incentive Compensation Plan.

Awards under our Incentive Compensation Plan are subject to any clawback policy of ours, which we may be required to adopt from time to time to comply with applicable laws. The administrator also may impose such other clawback, recovery or recoupment provisions with respect an award under our Incentive Compensation Plan as the administrator determines necessary or appropriate, including for example, reduction, cancellation, forfeiture or recoupment upon a termination of a participant’s employment for cause. Certain participants may be required to reimburse us for certain amounts paid under an award under our Incentive Compensation Plan in connection with certain accounting restatements we may be required to prepare due to our material noncompliance with any financial reporting requirements under applicable securities laws, as a result of misconduct.

-32-

Our board of directors and our compensation committee have the authority to amend, suspend or terminate our Incentive Compensation Plan, provided such action does not impair the existing rights of any participant with respect to any earned awards.

Potential Payments Upon Termination or Change of Control

Regardless of the manner in which a named executive officer’s service terminates, that named executive officer is entitled to receive amounts earned during his term of service, including unpaid salary and unused vacation, as applicable. In addition, each named executive officer is entitled to receive certain benefits upon Viracta’s termination of his or her employment without cause or his or her resignation for good reason, as provided above under “—Employment Arrangements.”

Each named executive officer holds stock options granted subject to the general terms of our 2021 Equity Incentive Plan. A description of the termination and change in control provisions in our 2021 Equity Incentive Plan and applicable to the stock options granted to Viracta’s named executive officers is provided below under “—Outstanding Equity Awards at Fiscal 2021 Year-End” and above under “—Employment Arrangements.”

Analysis of the Information Presented in the Pay Versus Performance Table

The Company generally seeks to incentivize long-term performance, and therefore does not specifically align performance measures with “compensation actually paid” (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, we are providing the following descriptions of the relationships between information presented in the Pay Versus Performance table.

Compensation Actually Paid and Net Income (Loss)

Because we are not a commercial-stage company, we did not have any revenue during the periods presented, other than a gain on a royalty purchase agreement with XOMA (US) LLC entered into in 2021. Consequently, the Company has not historically looked to net income (loss) as a performance measure for our executive compensation program. From 2022 to 2023, our net loss increased and the compensation actually paid for our PEO decreased. The average compensation actually paid to non-PEO NEOs saw a slight increase from 2022 to 2023 due to the departure of Dr. Rojkjaer and the hire of Dr. Cohen, which distorted the year-over-year comparison. From 2021 to 2022, our net loss increased when excluding one-time operating expenses in 2021 related to acquired in-process research and development of $88.5 million, and the compensation actually paid for both our PEOs and non-PEO NEOs decreased between 2021 and 2022.

Compensation Actually Paid and Cumulative TSR

As shown in the following graph, the compensation actually paid to Mr. Rothera, Dr. Royston and the average amount of compensation actually paid to our other named executive officers as a group during the periods presented are positively correlated. We utilize several performance measures to align executive compensation with our performance, but those tend not to be financial performance measures, such as TSR. For example, as described in more detail above in the section “Employment Arrangements,” part of the compensation our named executive officers are eligible to receive consists of annual cash bonuses which are designed to provide appropriate incentives to our executives to achieve defined annual corporate goals and to reward our executives for individual achievement of performance objectives. Additionally, we view stock options, which are an integral part of our executive compensation program, as related to company performance although not directly tied to TSR, because they provide value only if the market price of our common stock increases, and if the executive officer continues in our employment over the vesting period. These stock option awards strongly align our executive officers’ interests with those of our stockholders by providing a continuing financial incentive to maximize long-term value for our stockholders and by encouraging our executive officers to continue in our employment for the long-term.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth the beneficial ownership of our common stock as of April 22, 2024 by:

•

each person, or group of affiliated persons, known by us to beneficially own more than 5% of our common stock;

•

each of our named executive officers;

•

each of our directors; and

•

all of our executive officers and directors as a group.

We have determined beneficial ownership in accordance with the rules of the SEC, and thus it represents sole or shared voting or investment power with respect to our securities. Unless otherwise indicated, to our knowledge, the persons or entities identified in the table have sole voting power and sole investment power with respect to all shares shown as beneficially owned by them, subject to community property laws where applicable.

We have based our calculation of the percentage of beneficial ownership on 39,272,434 shares of our common stock outstanding as of April 22, 2024. We have deemed shares of our common stock subject to stock options that are currently exercisable or exercisable within 60 days of April 22, 2024, or issuable pursuant to RSUs which are subject to vesting and settlement conditions expected to occur within 60 days of April 22, 2024, to be outstanding and to be beneficially owned by the person holding the stock option or RSU for the purpose of computing the percentage ownership of that person. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address for each person or entity listed in the table is c/o Viracta Therapeutics, Inc., 2533 S. Coast Hwy. 101, Suite 210, Cardiff, California 92007.

RELATED PERSON TRANSACTIONS

Since January 1, 2022, we have not entered into any transactions, nor are there any currently proposed transactions to which we will be a party, in which:

•

the amounts involved exceeded or will exceed $120,000; and

•

any of our directors, nominees for director, executive officers or holders of more than 5% of our outstanding capital stock, or any immediate family member of, or person sharing the household with, any of these individuals or entities, had or will have a direct or indirect material interest.

Consulting Agreement with Daniel Chevallard

In connection with Mr. Chevallard’s resignation, we entered into a consulting agreement with Mr. Chevallard, as more fully described in the section titled “Executive Compensation—Employment Arrangements”.

Policies and Procedures for Related Person Transactions

We have adopted a formal, written policy regarding related person transactions. This written policy regarding related person transactions provides that a related person transaction is a transaction, arrangement or relationship or any series of similar transactions, arrangements or relationships, in which we are a participant and in which a related person has, had or will have a direct or indirect material interest and in which the aggregate amount involved exceeds $120,000. For purposes of this policy, a related person means any of our executive officers and directors (including director nominees), in each case at any time since the beginning of our last fiscal year, or holders of more than 5% of any class of our voting securities and any member of the immediate family of, or person sharing the household with, any of the foregoing persons.

Our audit committee has the primary responsibility for reviewing and approving, ratifying or disapproving related person transactions. In determining whether to approve, ratify or disapprove any such transaction, our audit committee will consider, among other factors, (1) whether the transaction is fair to us and on terms no less favorable than terms generally available to unaffiliated third parties under the same or similar circumstances, (2) the extent of the related person’s interest in the transaction, (3) whether there are business reasons for us to enter into such transaction, (4) whether the transaction would impair the independence of any of our outside directors and (5) whether the transaction would present an improper conflict of interest for any of our directors or executive officers.

The policy grants standing pre-approval of certain transactions, including (1) certain compensation arrangements for our directors or executive officers, (2) transactions with another company at which a related person’s only relationship is as a non-executive employee, director or beneficial owner of less than 10% of that company’s shares, provided that the aggregate amount involved does not exceed the greater of $200,000 or 5% of such company’s total annual revenues and the transaction is on terms no less favorable than terms generally available to unaffiliated third parties under the same or similar circumstances, (3) charitable contributions by us to a charitable organization, foundation or university at which a related person’s only relationship is as a non-executive employee or director, provided that the aggregate amount involved does not exceed the greater of $200,000 or 5% of such organization’s total annual receipts, (4) transactions where a related person’s interest arises solely from the ownership of our common stock and all holders of our common stock received the same benefit on a pro rata basis and (5) any indemnification or advancement of expenses made pursuant to our organizational documents or any agreement. In addition to our policy, our audit committee charter provides that our audit committee shall review and approve or disapprove any related person transactions.
