Proxy Statement for the 2024 Annual Meeting of Stockholders
To be held on June 25, 2024
Questions and Answers About These Proxy Materials and Voting
Why did I receive
a notice regarding
the availability of
proxy materials on
the internet?
Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials over the internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials (the “Notice”) because the Board of Directors (sometimes referred to as the “Board”) of Kronos Bio, Inc. (sometimes referred to as “we,” “us,” “our,” the “Company” or “Kronos Bio”) is soliciting your proxy to vote at the 2024 Annual Meeting of Stockholders (“Annual Meeting”), including at any adjournments or postponements of the meeting. The Annual Meeting will be held virtually on June 25, 2024 at 4:00 p.m. Eastern Time. You can attend the Annual Meeting by visiting www.virtualshareholdermeeting.com/KRON2024, where you will be able to listen to the meeting live, submit questions, and vote online. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice.
We intend to first mail the Notice on April 29, 2024 to all stockholders of record entitled to vote at the Annual Meeting.
Will I receive
any other proxy
materials by mail?
We may send you a proxy card, along with a second Notice, on or after May 9, 2024.
Why are we
holding a virtual
Annual Meeting?
We have implemented a virtual format for our Annual Meeting, which will be conducted via live audio webcast and online stockholder tools. We believe a virtual format helps to facilitate stockholder attendance and participation by enabling stockholders to participate fully, and equally, from any location around the world without person-to-person contact, at no cost (other than any costs associated with your internet access, such as usage charges from internet access providers and telephone companies). A virtual Annual Meeting makes it possible for more stockholders (regardless of size, resources or physical location) to have direct access to information more quickly, while saving the Company and our stockholders time and money. We also believe that the online tools we have selected will increase stockholder communication. For example, the virtual format allows stockholders to communicate with us in advance of, and during, the Annual Meeting

so they can ask questions of our Board or management. During the Annual Meeting, we may answer questions submitted during the Annual Meeting and address those asked in advance, to the extent relevant to the business of the Annual Meeting, as time permits. We do not intend to post questions received during the Annual Meeting to our website.
What do I need to
do to attend the
Annual Meeting?
You will be able to attend the Annual Meeting online, submit your questions during the meeting and vote your shares electronically at the meeting by visiting www.virtualshareholdermeeting. com/KRON2024. To participate in the Annual Meeting, you will need the control number included on your Notice or proxy card. The Annual Meeting webcast will begin promptly at 4:00 p.m. Eastern Time on June 25, 2024. We encourage you to access the meeting prior to the start time. Online check-in will begin at 3:45 p.m. Eastern Time, and you should allow ample time for the check-in procedures.
Who can vote at the Annual Meeting?
Only stockholders of record at the close of business on April 26, 2024 will be entitled to vote at the Annual Meeting. On this record date, there were 60,094,409 shares of common stock outstanding and entitled to vote. A list of our stockholders of record will be open for examination by any stockholder for the ten days ending the day prior to the Annual Meeting at our headquarters located at 1300 So. El Camino Real, Suite 400, San Mateo, California 94402. If you would like to view the list, please contact our Corporate Secretary to schedule an appointment by calling (650) 781-5200 or writing to the Corporate Secretary at the address above.

Stockholder of Record: Shares Registered in Your Name
If on April 26, 2024, your shares were registered directly in your name with Kronos Bio’s transfer agent, Equiniti Trust Company, LLC, then you are a stockholder of record. As a stockholder of record, you may vote live online at the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return the proxy card that may be mailed to you or vote by proxy over the telephone or on the internet as instructed below to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank
If on April 26, 2024 your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and the Notice is being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting. If your shares are held in street name and you desire to vote online during the Virtual Annual meeting, you should follow the instructions provided by your bank, broker or other holder of record to be able to participate in the meeting.

TABLE OF CONTENTS

What am I
voting on?
There are three matters scheduled for a vote:

Proposal 1: Election of the Board’s three nominees for director named herein to hold office until the 2027 Annual Meeting of Stockholders and their successors are duly elected and qualified, or until their earlier death, resignation or removal;

Proposal 2: Advisory approval of the compensation of the Company’s Named Executive Officers, as disclosed in this proxy statement in accordance with SEC rules;

Proposal 3: Ratification of the selection, by the Audit Committee of the Board, of Ernst & Young LLP as the independent registered public accounting firm of the Company for its fiscal year ending December 31, 2024.
What if another
matter is properly brought before the meeting?
The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment. Discretionary authority for them to do so is provided for in the proxy card and other forms of proxy.
How do I vote?
You may vote “For” all the nominees to the Board of Directors, you may “Withhold” your vote for all nominees, or you may “Withhold” your vote for any nominee you specify. For both of the other proposals to be voted on, you may vote “For” or “Against” or abstain from voting.

The procedures for voting are fairly simple as described below:

Stockholder of Record: Shares Registered in Your Name
If you are a stockholder of record, you may vote live online at the Annual Meeting, vote by proxy over the telephone, vote by proxy through the internet or vote by proxy using a proxy card that you may request or that we may elect to deliver at a later time. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote live online even if you have already voted by proxy.

What happens if I do not vote?
Stockholder of Record: Shares Registered in Your Name
If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the internet or live online at the Annual Meeting, your shares will not be voted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank
If you are a beneficial owner and do not instruct your broker, bank, or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the New York Stock Exchange (“NYSE”) deems the particular proposal to be a “routine” matter. Brokers and nominees can use their discretion to vote “uninstructed” shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the NYSE, “non-routine” matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested), executive compensation (including any advisory stockholder votes on executive compensation and on the frequency of stockholder votes on executive compensation), and certain corporate governance proposals, even if management-supported. Accordingly, your broker or nominee may not vote your shares on Proposals 1 or 2 without your instructions, but may vote your shares on Proposal 3 even in the absence of your instruction.

If you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.
What if I return a proxy card or otherwise vote but do not make specific choices?
If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, (i) “For” the election of the three nominees for director; (ii) “For” the advisory approval of executive compensation; and (iii) “For” the ratification of the selection by the Audit Committee of the Board of Directors of Ernst & Young LLP as the independent registered public accounting firm of the Company for its fiscal year ending December 31, 2024. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card or other form of proxy) will vote your shares using his or her best judgment.
Who is paying for this proxy solicitation?
We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.
What does it mean if I receive more than one Notice?
If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each of the Notices to ensure that all of your shares are voted.

Can I change my vote after submitting my proxy?
Stockholder of Record: Shares Registered in Your Name
Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

•    You may submit another properly completed proxy card with a later date.
•    You may grant a subsequent proxy by telephone or through the internet.

•    You may send a timely written notice that you are revoking your proxy to the Company’s Secretary at 1300 So. El Camino Real, Suite 400, San Mateo, California 94402. Such notice will be considered timely if it is received at the indicated address by the close of business on the business day preceding the date of the Annual Meeting.

•    You may attend and vote online at the Annual Meeting (although attendance at the Annual Meeting will not, by itself, revoke a proxy).

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

Beneficial Owner: Shares Registered in the Name of Broker or Bank
If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.
When are stockholder proposals and director nominations due for next year’s annual meeting?
To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 30, 2024, to Kronos Bio, Inc., Attn: Secretary, 1300 So. El Camino Real, Suite 400, San Mateo, California 94402. If you wish to submit a proposal (including a director nomination) at the meeting, you must do so between February 25, 2025 and March 27, 2025. You are also advised to review the Company’s Bylaws, which contain additional requirements relating to advance notice of stockholder proposals and director nominations.

In addition to satisfying the foregoing requirements under the Company’s Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our Board’s nominees must provide notice that sets forth any additional information required by Rule 14a-19 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
How are votes counted?
Votes will be counted by the inspector of election appointed for the meeting, who will separately count, for the proposal to elect directors, votes “For,” “Withhold” and broker non-votes; and with respect to each other proposal, votes “For,” “Against,” abstentions and, if applicable, broker non-votes. Abstentions will be counted towards the vote total for Proposal 2 and Proposal 3, and will have the same effect as votes “Against” votes. Broker non-votes will be counted towards the presence of a quorum but will not be counted towards the vote total for any proposal.
What are “broker non-votes”?
As discussed above, when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed by the NYSE to be “non-routine,” the broker or nominee cannot vote the shares. These unvoted shares are counted as “broker non-votes.”

2024 Proxy Statement

TABLE OF CONTENTS

How many votes are needed to approve each proposal?
For the election of directors, the three nominees receiving the most “For” votes from the holders of shares present or represented by proxy and entitled to vote on the election of directors will be elected. Only votes “For” will affect the outcome.

Proposal 2, advisory approval for the compensation of the Company’s named executive officers, will be considered to be approved if it receives “For” votes from the holders of the majority of shares present at the Annual Meeting or represented by proxy and entitled to vote on the matter. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.

To be approved, Proposal 3, ratification of the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm for its fiscal year ending December 31, 2024, must receive “For” votes from the holders of a majority of shares present at the Annual Meeting or represented by proxy and entitled to vote on the matter. If you “Abstain” from voting, it will have the same effect as an “Against” vote. We do not expect there to be any broker non-votes for this proposal.
What is the quorum requirement?
A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote is present at the meeting or represented by proxy. On the record date, there were 60,094,409 shares outstanding and entitled to vote. Thus, the holders of at least 30,047,206 shares must be present at the meeting or represented by proxy at the meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote live online at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares present at the meeting or represented by proxy may adjourn the meeting to another date.
How can I find out the results of the voting at the Annual Meeting?
Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

Proposal 1
Election of Directors
Our Board of Directors is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a three-year term. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified.
Our Board of Directors currently consists of nine members. There are three directors in Class I, whose term of office expires at the Annual Meeting: Norbert Bischofberger, Ph.D., Roger D. Dansey, M.D. and Taiyin Yang, Ph.D. Dr. Bischofberger, Dr, Dansey and Dr. Yang have been nominated for re-election at the Annual Meeting.
Dr. Bischofberger, Dr. Dansey and Dr. Yang are each current directors of the Company. Drs. Bischofberger and Yang were each elected by our stockholders at our 2021 annual meeting and Dr. Dansey was appointed by our Board in April 2023. The nominees were each recommended by the Nominating and Corporate Governance Committee of the Board for nomination to the Board at the Annual Meeting. Each nominee for director to be elected at the Annual Meeting will serve for a three-year term until our 2027 Annual Meeting of Stockholders, and until his or her successor is duly elected and qualified, or until his or her earlier death, resignation or removal. It is our policy to invite directors and nominees for director to attend the Annual Meeting. All of our directors other than Mr. Tanen, Dr. Belldegrun, and Dr. Yang attended our 2023 Annual Meeting of Stockholders.
Directors are elected by a plurality of the votes of the holders of shares present at the Annual Meeting or represented by proxy and entitled to vote at the Annual Meeting. Accordingly, the three nominees receiving the most “For” votes (among votes properly cast at the Annual Meeting or by proxy) will be elected. If no contrary indication is made, shares represented by executed or authenticated proxies will be voted “For” the election of the three nominees named above or, if any nominee becomes unavailable for election as a result of an unexpected occurrence, “For” the election of a substitute nominee designated by our Board. Each nominee has agreed to serve as a director if elected and we have no reason to believe that any nominee will be unable to serve.
The Nominating and Corporate Governance Committee seeks to assemble a Board that, as a whole, possesses the appropriate balance of professional and industry knowledge, financial expertise and high-level management experience necessary to oversee and direct the Company’s business. The Nominating and Corporate Governance Committee also seeks to attain diversity and balance among directors of race, gender, geography, thought, viewpoints, and backgrounds. To those ends, the Nominating and Corporate Governance Committee has identified and evaluated nominees in the broader context of the Board’s overall composition, with the goal of recruiting members who complement and strengthen the skills of other members through diversity and who also exhibit integrity, collegiality, sound business judgment, and other qualities that the Nominating and

Corporate Governance Committee views as critical to effective functioning of the Board. The brief biographies below include information, as of the date of this proxy statement, regarding the specific and particular experience, qualifications, attributes or skills of each director/nominee that led the Nominating and Corporate Governance Committee to believe that that nominee should continue to serve on the Board. However, each of the members of the Nominating and Corporate Governance Committee may have a variety of reasons why he or she believes a particular person would be an appropriate nominee for the Board, and these views may differ from the views of other members.
The following is a brief biography of each director nominee, each director in the classes who are not standing for election at the Annual Meeting and whose term will continue after the Annual Meeting, and each of our executive officers.

Dr. Bischofberger joined Gilead in 1990 as Director of Chemistry after having worked as a Senior Scientist in Genentech’s DNA Synthesis Group from 1986 until 1990. During his 28-year tenure at Gilead, Dr. Bischofberger presided over the development and approval of more than 25 medicines, which led the transformation of the treatment of a range of serious diseases such as HIV, HCV and lymphoma. Dr. Bischofberger was part of the core management team that grew Gilead from less than 50 employees with no revenues to 10,000 employees with $25 billion in revenue. Dr. Bischofberger received a Ph.D. in organic chemistry from Zurich’s Eidgenössische Technische Hochschule and performed postdoctoral research in steroid chemistry at Syntex.

Information Regarding the Board of Directors and Corporate Governance
Independence of the Board of Directors
As required under the Nasdaq Stock Market (“Nasdaq”) listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by its board of directors. The Board consults with the Company’s counsel to ensure that the Boards’ determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.
Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent registered public accounting firm, the Board has affirmatively determined that all of our directors other than Dr. Bischofberger, Mr. Kazam and Mr. Tanen are independent directors, as defined by Rule 5605(a)(2) of the Nasdaq Listing Rules.
Board Leadership Structure
Our Board is currently chaired by Dr. Belldegrun, who has authority, among other things, to call and preside over Board meetings, set meeting agendas and determine materials to be distributed to the Board. Accordingly, the chairman has substantial ability to shape the work of the Board. We believe that separation of the positions of chairman and chief executive officer reinforces the independence of the Board in its oversight of our business and affairs. In addition, we have a separate chair for each committee of our Board. The chairs of each committee are expected to report periodically to our Board on the activities of their committees in fulfilling the responsibilities as detailed in the respective charters or advise of any shortcomings that may be identified.

Role of the Board in Risk Oversight
One of the key functions of our Board is informed oversight of our risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through the Audit Committee. The Audit Committee receives reports from management periodically regarding our assessment of risks, including cybersecurity risks. In addition, the Audit Committee reports regularly to our Board, which also considers our risk profile. The Audit Committee and our Board focus on the most significant risks we face and our general risk management strategies. While our Board oversees risk management, management is responsible for day-to-day risk management processes. Our Board expects management to consider risk and risk management in each business decision, to proactively develop and monitor risk management

strategies and processes for day-to-day activities, and to effectively implement risk management strategies adopted by the Audit Committee and our Board. We believe this division of responsibilities is the most effective approach for addressing the risks we face and that our Board’s leadership structure, which also emphasizes the independence of our Board in its oversight of its business and affairs, supports this approach.
Meetings of the Board of Directors
Our Board of Directors met six times during the last fiscal year. Each Board member attended at least 75% of the meetings of the Board and of the committees on which he or she served.

considering questions of possible conflicts of interest of directors as such questions arise; and
reviewing and assessing on an annual basis the performance of the Nominating and Corporate Governance Committee and the Nominating and Corporate Governance Committee charter.
We believe that the composition and functioning of our Nominating and Corporate Governance Committee comply with all applicable requirements of the Sarbanes-Oxley Act, and all applicable SEC and Nasdaq rules and regulations. We intend to comply with future requirements to the extent they become applicable to us.
The Nominating and Corporate Governance Committee believes that the candidates for director, both individually and collectively, have the integrity, experience, judgment, commitment (including having sufficient time to devote to us and level of participation), skills and expertise appropriate for us. In assessing the directors, both individually and collectively, the Nominating and Corporate Governance Committee considers our current needs, and the needs of the Board, to maintain a balance of knowledge, experience, capability, race, gender, geographical representation, thought, viewpoints, backgrounds, skills, and expertise. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time.
The Nominating and Corporate Governance Committee uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. Candidates for director nominees are reviewed in the context of the current composition of the Board, our operating requirements and the long-term interests of stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee typically considers diversity (including with respect to race, gender, geography, thought, viewpoints, and backgrounds), age, skills and such other factors as it deems appropriate given our current needs and the needs of the Board, to maintain a balance of knowledge, experience and capability, especially in light of the existing composition of the Board and in light of the stage of the Company. In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews these directors’ overall service to us during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors’ independence. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. To the extent any search firm is retained to assist the Nominating and Corporate Governance Committee in seeking candidates for the Board, the search firm will be instructed to seek to include diverse candidates in terms of race, gender, geography, thought, viewpoints, backgrounds, skills, experience, and expertise from, among other areas, professional and academic areas relevant to the Company’s area of focus. In addition, the Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board by majority vote.
The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate 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. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: 1300 So.

The purpose of the Corporate Strategy Committee is to assist the Board in fulfilling its responsibilities to (1) oversee the development, with our Chief Executive Officer and our other management, of our strategic objectives; (2) oversee our corporate/business development strategic planning; and (3) review and evaluate our specific strategic initiatives, including the terms, risks and opportunities relating to such initiatives. The Board has adopted a written Corporate Strategy Committee charter that is available to stockholders on the Company’s website at www.kronosbio.com.
Stockholder Communications with the Board of Directors
The Board has adopted a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board may do so by sending written communications addressed to: Kronos Bio, Inc., Attn: Secretary, 1300 So. El Camino Real, Suite 400, San Mateo, California 94402. These communications will be reviewed by the Secretary, who will determine whether the communication is appropriate for presentation to the Board or the relevant director. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations and hostile communications).
Code of Ethics
The Company has adopted the Code of Business Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on the Company’s website at www.kronosbio.com. The Nominating and Corporate Governance Committee of our Board is responsible for overseeing our Code of Business Conduct and Ethics and any waivers applicable to any director, executive officer or employee. If the Company makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver on its website.

Proposal 2
Advisory Vote on Executive
Compensation
At our 2022 Annual Meeting of Stockholders, the stockholders indicated their preference that we solicit a non-binding advisory vote on the compensation of our named executive officers, commonly referred to as a “say-on-pay” vote, every year. The Board has adopted a policy that is consistent with that preference. In accordance with that policy, this year, we are asking the stockholders to approve, on an advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with SEC rules.
This vote is not intended to address any specific item of compensation, but rather the overall compensation of the Company’s named executive officers and the philosophy, policies and practices described in this proxy statement. The compensation of the Company’s named executive officers subject to the vote is disclosed in the compensation tables and the related narrative disclosure contained in this proxy statement. As discussed in those disclosures, we believe that our compensation policies and decisions are performance driven and foster a performance-oriented culture, are strongly aligned with our stockholders’ interests and are consistent with current market practices. Compensation of the Company’s named executive officers is designed to enable the Company to attract and retain talented and experienced executives to lead the Company successfully in a competitive environment.
Accordingly, the Board is asking the stockholders to indicate their support for the compensation of the Company’s named executive officers as described in this proxy statement by casting a non-binding advisory vote “For” the following resolution:
“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the compensation tables and narrative discussion, is hereby APPROVED.”
Because the vote is advisory, it is not binding on the Board or the Company. Nevertheless, the views expressed by the stockholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.
Advisory approval of this proposal requires the vote of the holders of a majority of the shares present at the Annual Meeting or represented by proxy and entitled to vote on the matter at the Annual Meeting. Unless the Board decides to modify its policy regarding the frequency of soliciting advisory votes on the compensation of the Company’s named executive officers, the next scheduled say-on-pay vote will be at the 2025 Annual Meeting of Stockholders.

Proposal 3
Ratification of Selection
of Independent Registered
Public Accounting Firm
The Audit Committee of the Board has selected Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Ernst & Young LLP has audited the Company’s financial statements since 2019. Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.
Neither the Company’s Bylaws nor other governing documents or law require stockholder ratification of the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm. However, the Audit Committee of the Board is submitting the selection of Ernst & Young LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.
The affirmative vote of the holders of a majority of the shares present at the Annual Meeting or represented by proxy and entitled to vote on the matter at the Annual Meeting will be required to ratify the selection of accounting firm.

Executive Compensation Philosophy and Objectives
We operate in a highly competitive and rapidly evolving market, and our ability to compete is directly correlated to our ability to recruit and retain talented executives and employees. Our executive compensation program is intended to incentivize their achievement and align their interests with our stockholders. Our five principal objectives are to:
Attract, retain and inspire the most talented executives in our industry;
Link rewards to the achievement of critical strategic priorities;
Create incentives for our executive officers to further our ability to create long-term stockholder value;
Kronos Bio

2024 Proxy Statement

TABLE OF CONTENTS

Provide appropriate level of risk and reward relative to an executive’s position with us; and
Differentiate compensation based on individual performance, rewarding our strongest executive performance.
The compensation of our named executive officers generally consists of a base salary, annual cash bonus, and equity incentive awards, as well as the employee benefits that are generally made available to our salaried employees.
Process for Setting Executive Compensation
We seek to foster a performance-oriented culture, where individual performance is aligned with organizational objectives. To achieve this, we evaluate and reward our executive officers based on their contributions to the achievement of annual goals and objectives set early in the year. Performance is reviewed at least annually through processes discussed further below, with a focus on our research, clinical, regulatory, financial and operational performance, and in view of economic and financial conditions affecting the performance period.
Role of Compensation Committee and Board of Directors
Our Compensation Committee is responsible for determining the compensation of our executive officers, other than our Chief Executive Officer (“CEO”), and for making recommendations to the Board with respect to our CEO’s compensation. In making compensation decisions, our Compensation Committee reviews our management regarding base salaries, annual bonus, and equity incentive awards for our executive officers (other than the CEO) as well as recommendations and information provided by our independent compensation consultant. Our Compensation Committee is ultimately responsible for determining (or recommending, in the case of our CEO) the compensation of our executive officers. Our CEO is not present for any discussions of the Compensation Committee or Board regarding his performance or compensation.
The Compensation Committee’s authority, duties and responsibilities are further described in its charter. See “Information Regarding Committees of the Board of Directors – Compensation Committee” above.
The Compensation Committee retains a compensation consultant (as described below) to provide support in its review and assessment of our executive compensation programs.
Compensation Committee Processes and Procedures
Typically, the Compensation Committee meets at least quarterly and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with the Chief Executive Officer, Senior Vice President, Corporate Operations and Legal, and Pearl Meyer and Partners, LLC (“Pearl Meyer”), the Compensation Committee’s independent compensation consultant. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, provide financial or other background information or advice, or otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive

advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.
During the past fiscal year, after taking into consideration the six factors prescribed by the SEC and Nasdaq that did not raise a conflict of interest, the Compensation Committee continued its engagement of Pearl Meyer as a compensation consultant. The Compensation Committee requested that Pearl Meyer review industry-wide compensation practices and trends to assess the competitiveness of our executive and non-employee director compensation programs.
As part of its engagement, Pearl Meyer was requested by the Compensation Committee to review and propose changes to comparative group of companies and to perform analyses of competitive performance and compensation levels for that group. Pearl Meyer also meets with certain members of management and human resources to learn more about the Company’s business operations and strategy, key performance metrics and strategic goals, as well as the labor markets in which the Company competes. Pearl Meyer ultimately developed recommendations primarily pertaining to our peer group and executive and non-employee director compensation determinations that were presented to the Compensation Committee for its consideration and to the Board for its information. Following an active dialogue with Pearl Meyer, the Compensation Committee recommended that the Board approve certain recommendations of Pearl Meyer.
Role of Management
In making compensation decisions, our Compensation Committee considers the recommendations of our CEO, with input from our Senior Vice President, Corporate Operations and Legal. Our CEO makes recommendations to our Compensation Committee with respect to executive officers, but does not participate in deliberations or determination of his own compensation. Our Compensation Committee reviews and makes a recommendation to the full Board related to the approval of corporate objectives and goals pursuant to the powers delegated under its charter. The CEO annually leads the development of our corporate objectives and goals, which are typically reviewed and approved by the Compensation Committee and then our Board. Our CEO provided the Company’s business and operations perspective to help our Compensation Committee review our 2023 goal progress. Other than as described above, no other executive officers participate in the determination or recommendation of the amount or form of executive officer compensation.

Role of Compensation Consultant
Our Compensation Committee engaged Pearl Meyer as its independent compensation consultant. Pearl Meyer has assisted our Compensation Committee by providing analysis and recommendations regarding trends in executive compensation, peer group selection, compensation practices, and equity plan utilization.

Elements of 2023 Compensation
Annual Base Salary
The base salaries of our executive officers are designed to compensate them for day-to-day services rendered during the fiscal year. Appropriate base salaries are used to recognize the experience, skills, knowledge, and responsibilities required of each executive officer, and to allow us to attract and retain individuals capable of leading us to achieve our business goals in competitive market conditions.
The base salaries of our executive officers are reviewed at least annually by our Compensation Committee and adjustments are made to reflect Company and individual performance, as well as competitive market practices. Our Compensation Committee also takes into account subjective performance criteria, such as an executive officer’s ability to lead, organize and motivate others, develop the skills necessary to grow with us as an organization, set realistic goals to be achieved in their respective area, and recognize and pursue new business opportunities that enhance our growth and success. Our Compensation Committee does not apply specific formulas to determine increases, but instead evaluates each executive officer’s contributions to our long-term success. Annual adjustments to base salaries are effective as of January 1 of each year, with mid-year adjustments to base salaries made under special circumstances, such as promotions or increased responsibilities.
The 2023 base salaries for our named executive officers were as follows:

Annual Bonus Opportunity
Our named executive officers are eligible to receive performance-based cash bonuses, which are designed to provide appropriate incentives to our executive officers to achieve pre-established annual corporate goals and reward them for individual performance towards these goals. The annual performance-based bonus each current named executive officer is eligible to receive is generally based on the extent to which we achieve the corporate goals that the Board establishes early each year. At the end of the year, the Board and Compensation Committee review our performance and evaluate the extent to which we achieved each of these corporate goals. Generally, the Board and Compensation Committee, as applicable, will assess each named executive officer’s individual contributions toward reaching our annual corporate goals.

The corporate goals used in our 2023 annual cash bonus plan were proposed by management and reviewed and approved by our Compensation Committee and our Board. The Board considered and assigned a relative weight to each corporate goal to appropriately focus efforts on achievements that were intended to enhance long-term stockholder value.
Our corporate goals for 2023, and the relative weighting of each corporate goal, were as follows:
For our KB-0742 program:
Enrolling a minimum of twenty-five patients across the two expansion cohorts and 80mg dose escalation cohort (weighted at 20%)
Having at least fifteen cohort-B defined evaluable patients (either dosed for a minimum of two cycles or discontinued earlier because of pharmacodynamics) to enable a response assessment (weighted at 20%)
Determining the safety and tolerability of the 80mg dose (weighted at 15%)
For our lanraplenib program:
Enrolling three cohorts in the dose escalation stage of the lanraplenib/gilteritinib phase 1b/2 trial or declare a recommended phase 2 dose (weighted at 20%)
Stretch goal: Enrolling the first patient in a fourth cohort or expansion (weighted at an additional 5%)
For our discovery programs:
Nominating a new development candidate originated from internal efforts (weighted at 10%)
Advancing one hit-to-lead project derived from internal efforts to the lead optimization stage (weighted at 5%)
Stretch goal: Proposing a compound for nomination as a discovery hit under the company’s Genentech collaboration (weighted at an additional 5%)
In our business development efforts:
Closing either (i) a platform/discovery collaboration, (ii) a regional partnering transaction for KB-0742 or (iii) another strategic transaction (weighted at 5%)
Stretch goal: Extending expected cash runway through cash inflows into 2026 (weighted at an additional 5%)
In our General and Administrative (“G&A”) efforts:
Increasing overall employee engagement score by at least ten percentage points with an at least 85% participation rate (weighted at 5%)

In December 2023 and January 2024, our Compensation Committee and our Board reviewed our progress against these 2023 corporate goals and determined that, on an overall basis, we had attained 100% of our corporate goals. Our Compensation Committee and our Board determined that we had achieved all of our goals with respect to our KB-0742 and lanraplenib programs, including the lanraplenib stretch goal, totaling 80%. With respect to the discovery goals, the Compensation Committee and the Board determined we achieved both goals, though not the stretch goal, totaling an additional 15%. The Compensation Committee and the Board determined neither business development goal was met. With respect to the G&A goal, the Compensation Committee and the Board determined the goal was met and awarded an additional 5%.
In recognition of their efforts toward our achievement of such corporate goals and milestones, our Compensation Committee approved awarding Dr. DiMartino and Ms. Kosacz 100% of their respective target annual cash bonus opportunity for 2023. Though Dr. Bischofberger also achieved 100% of his bonus opportunity, he elected to receive his bonus in restricted stock units (“RSUs”), which were granted by the Board on February 15, 2024.
The 2023 annual bonus payments are summarized in the tables below.

Long-Term Incentive Compensation
We provide long-term incentive compensation to our executive officers through the grant of equity awards. We believe that equity awards incentivize our executive officers to execute our long-term strategic plan with the goal of creating value for our stockholders. We also believe equity awards foster an ownership culture, which is critical for aligning financial interests with that of our stockholders. In addition, the vesting requirements of our equity awards contributes to executive retention by providing an added incentive to our executive officers to remain employed by us during the vesting period.
Generally, equity awards are granted when an executive officer commences employment with us. Thereafter, equity awards may be granted at varying times and in varying amounts at the discretion of our Compensation Committee or, if awards are being granted to the CEO, at the discretion of the Board. Grants are generally made once a year, unless such executive officer is promoted or to recognize outstanding performance. None of our executive officers is currently a party to an employment agreement that provides for an automatic grant of stock options or other equity awards.
Before approving equity awards, the Compensation Committee receives preliminary recommendations for equity awards from our CEO for executive officers (other than himself) for annual awards and awards made in connection with an executive’s hire or promotion. The Compensation Committee then reviews our compensation consultant’s market-based recommendations based on our peer group and survey data, and approves equity awards for our executive officers, with the exception of our CEO whose grant is reviewed and approved by the Board once it receives the recommendation of the Compensation Committee.

Potential Payments Upon Termination or Change in Control
Our executive officers, including our named executive officers, are or were entitled to certain severance and change of control payments and benefits pursuant to our Severance and Change in Control Plan (the “Change in Control Plan”). The Change in Control Plan provides for, in the event of an involuntary termination of employment without “cause” or a resignation with “good reason,” and subject to our receipt of an effective waiver and release of claims from the executive, a combination of (1) cash severance for the severance period and (2) the payment or reimbursement of premiums or continued coverage under group health plans for the severance period. The severance period is 24 months in the case of our Chief Executive Officer, and 12 months in the case of our other named executive officers.
In the event that the involuntary termination of employment occurs within the period commencing as of the closing of the change of control of the Company and ending 12 months after a change in control of the Company, then the participants in the Change in Control Plan are entitled to the same benefits described above, other than our former Chief Financial Officer, former Chief Medical Officer and Executive Vice President of Research and Development, former General Counsel and Chief Operating Officer, and former Chief Scientific Officer, whose severance periods were 18 months. In addition, our Chief Executive Officer would be entitled to 200% of his annual target bonus and our other named executive officers would be entitled to 150% of his or her annual target bonus, and each of our named executive officers would be entitled to accelerated vesting of outstanding equity compensation awards.
Under the Change in Control Plan, the term “cause” generally means (i) the employee’s commission of any crime involving fraud, dishonesty or moral turpitude; (ii) the employee’s attempted commission of or participation in a fraud or act of dishonesty against us that results in (or might have reasonably resulted in) material harm to our business; (iii) the employee’s intentional, material violation of any contract or agreement between us and the employee or any statutory duty that the employee owes to us; or (iv) the employee’s conduct that constitutes gross insubordination, incompetence or habitual neglect of duties and that results in (or might have reasonably resulted in) material harm to our business. The term “change in control” generally means (1) the acquisition by any person or company of more than 50% of the combined voting power of our then outstanding stock, (2) a merger, consolidation or similar transaction in which our stockholders immediately before the transaction do not own, directly or indirectly, more than 50% of the combined voting power of the surviving entity (or the parent of the surviving entity) in substantially the same proportions as their ownership immediately prior to such transaction, (3) a sale, lease, exclusive license or other disposition of all or substantially all of our assets other than to an entity more than 50% of the combined voting power of which is owned by our stockholders in substantially the same proportions as their ownership of our outstanding voting securities immediately prior to such transaction, or (4) a complete dissolution or liquidation of the company.
The term “good reason” generally means (i) a material reduction of such employee’s annual base salary, which is a reduction of at least 10% of such employee’s base salary (unless pursuant to a salary reduction program applicable generally to the Company’s similarly situated employees); (ii) a material reduction in such employee’s authority, duties or responsibilities; (iii) a relocation of such employee’s principal place of employment with the Company (or successor to the Company, if applicable) to a place that increases such employee’s one-way commute by more than 50 miles as compared to such employee’s then-current principal place of employment immediately prior to such relocation (excluding regular travel in the ordinary course of business).

Health and Welfare Benefits
Our named executive officers are or were eligible to participate in our employee benefit plans, including our medical, dental, group term life, disability and accidental death and dismemberment insurance plans, in each case on the same basis as all of our other employees. We also maintain a Section 401(k) plan for our employees, including our named executive officers, as discussed in the section below entitled “— Section 401(k) Plan.”
Kronos Bio

2024 Proxy Statement

TABLE OF CONTENTS

Section 401(k) Plan
We maintain a defined contribution employee retirement plan (the “401(k) Plan”) for our employees. Our executive officers are eligible to participate in the 401(k) Plan on the same basis as our other employees. The 401(k) Plan provides that each participant may contribute up to the lesser of 1-80% of the participant’s compensation, or the statutory limit, which was $22,500 for calendar year 2023. Participants 50 years or older could also make “catch-up” contributions of up to $7,500 in 2023. We currently make matching contributions to each participant’s account equal to 100% of eligible contributions up to the first 4% of eligible compensation. Participant contributions are held by the plan’s trustee and invested pursuant to the participant’s instructions.
Perquisites
We generally do not provide perquisites or personal benefits to our named executive officers. We do, however, from time to time, provide relocation benefits to our named executive officers as determined in the Board’s discretion.
Post-Employment Compensation
Our named executive officers are or were entitled to certain severance and change of control payments and benefits pursuant to our Change in Control Plan, as described in more detail in the section entitled “—Potential Payments Upon Termination or Change of Control.”
Given the industry in which we operate and the range of strategic initiatives that we may explore, we believe these arrangements are an essential element of our executive compensation package and assist us in recruiting and retaining highly talented individuals. In addition, as we believe it may be difficult for our executive officers to find comparable employment following an involuntary termination of employment in connection with or following a change of control of the Company, these payments and benefits are intended to ease the consequences to an executive officer of an unexpected termination of employment. By establishing these payments and benefits, we believe we can mitigate the distraction and loss of executive officers that may occur in connection with rumored or actual fundamental corporate changes and thereby protect stockholder interests while a transaction is under consideration or pending.
Accounting and Tax Considerations
Under Financial Accounting Standard Board ASC Topic 718, or ASC Topic 718, we are required to estimate and record an expense for each share-based payment award (including stock options) over the vesting period of the award. We record share-based compensation expense on an ongoing basis according to ASC Topic 718. Our Compensation Committee has considered, and may in the future consider, the grant of performance-based or other types of stock awards to our executive officers in lieu of or in addition to stock options in light of the accounting impact of ASC Topic 718 and other considerations.
For federal income tax purposes, publicly-traded companies may be prohibited under Section 162(m) of the Code (“Section 162(m)”) from deducting employee remuneration in excess of $1 million paid to their chief executive officer, chief financial officer, any other executive officer whose total compensation is required to be reported to stockholders under the Exchange Act by reason of such individual being among the three highest compensated executive officers for the tax year, and any executive officer who was subject to the deduction limit in any tax year beginning after December 31, 2016. Even if Section 162(m) may limit the compensation deduction, our Board and our Compensation Committee believe our compensation policies and practices should be designed to help us meet our established goals and objectives. While our Board and Compensation Committee will consider the impact of the Section 162(m) deduction limitation, they intend to continue to compensate our named executive officers in a manner that is in the best interests of our stockholders and reserve the right to make compensation decisions that may not be deductible under Section 162(m) where they determine the compensation to be appropriate and in the best interests of the Company and our stockholders.

compensation with Company performance, those Company measures are not financial performance measures and are therefore not presented in the Item 402(v) Pay Versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s 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 Item 402(v) Pay Versus Performance table above.
Compensation Actually Paid and Net Loss
The chart below compares CAP to our PEO, the average CAP to our Non-PEO NEOs, and the Company’s net income (loss), over the three years presented in the table.
Because the Company is a pre-commercial stage company, we had no revenue during the periods presented. Consequently, we do not use net income (loss) as a performance measure in our executive compensation program. Therefore, we do not believe there is any meaningful relationship between our net loss and compensation actually paid to our NEOs during the periods presented.

The weighted average exercise price is calculated based solely on outstanding stock options. It does not take into account the shares of our common stock underlying restricted stock units, which have no exercise price.
(2)
As of December 31, 2023, under our 2017 Equity Incentive Plan (the “Prior Plan”), the number of outstanding awards under column (a) includes 2,261,827 shares which are issuable upon the exercise of outstanding options (including options that are immediately exercisable) at a weighted-average exercise price of $4.62.
(3)
In October 2020, we adopted our 2020 Equity Incentive Plan (the “2020 Plan”) which replaced the Prior Plan. Initially, the aggregate number of shares of our common stock that may be issued under the 2020 Plan was 11,938,152. Additionally, in each year, commencing in 2021 and ending in 2030, the number of shares authorized for issuance under the 2020 Plan is automatically increased by a number equal to: (a) 5% of the total number of shares of capital stock outstanding on December 31 of the preceding calendar year; or (b) such lesser number of shares of common stock as is determined by our Board or a designated committee thereof for the applicable year. As of December 31, 2023, under our 2020 Plan the number of outstanding awards under column (a) includes: (1) 5,934,979 shares to be issued upon the exercise of outstanding options (including options that are immediately exercisable) at a weighted-average exercise price of $10.62; and (2) 1,635,416 shares issuable upon the vesting of outstanding restricted stock units. On January 1, 2024, the number of shares authorized for issuance under the 2020 Plan was 20,417,192 shares.
(4)
In October 2020, we adopted our Employee Stock Purchase Plan (the “ESPP”). The ESPP initially authorized the issuance of 688,000 shares of our common stock pursuant to purchase rights granted to our employees or to employees of any of our designated affiliates. Additionally, in each year, commencing in 2021 and ending in 2030, the number of shares authorized for issuance under the 2020 ESPP is automatically increased by a number equal to the lesser of: (a) 1% of the total number of shares of capital stock outstanding on December 31 of the preceding calendar year; (b) 1,376,000 shares; or (c) such lesser number of shares of our common stock as is determined by our Board for the applicable year. The ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Code. On January 1, 2024, the number of shares authorized for issuance under the ESPP was 2,383,807 shares.

Transactions with Related Persons
Related-Person Transactions Policy and Procedures
We have adopted a written related-person transactions policy that sets forth our policies and procedures regarding the identification, review, consideration and oversight of “related-person transactions.” For purposes of our policy only, a “related-person transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we and any “related person” are participants involving an amount that exceeds $120,000. Transactions involving compensation for services provided to us as an employee, consultant or director are not considered related-person transactions under this policy. A related person is any executive officer, director, nominee to become a director or a holder of more than five percent of our common stock, including any of their immediate family members and affiliates, including entities owned or controlled by such persons.
Under the policy, where a transaction has been identified as a related-person transaction, management must present information regarding the proposed related-person transaction to our Audit Committee (or, where review by our Audit Committee would be inappropriate, to another independent body of our Board) for review. The presentation must include a description of, among other things, all of the parties thereto, the direct and indirect interests of the related persons, the purpose of the transaction, the material facts, the benefits of the transaction to us and whether any alternative transactions are available, an assessment of whether the terms are comparable to the terms available from unrelated third parties and management’s recommendation. To identify related-person transactions in advance, we rely on information supplied by our executive officers, directors and certain significant stockholders. In considering related-person transactions, our Audit Committee or another independent body of our Board takes into account the relevant available facts and circumstances including, but not limited to:
the risks, costs and benefits to us;
the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated;
the terms of the transaction;
the availability of other sources for comparable services or products; and
the terms available to or from, as the case may be, unrelated third parties.
In the event a director has an interest in the proposed transaction, the director must recuse himself or herself from the deliberations and approval.

Certain Relationships and Related-Person Transactions
The following sections summarize transactions since January 1, 2022 to which we have been a party, in which the amount involved in the transaction exceeded $120,000 and in which any of our directors, executive officers or, to our knowledge, beneficial owners of more than 5% of our capital stock, including any of their immediate family members and affiliates, including entities owned or controlled by such persons, had or will have a direct or indirect material interest, other than equity and other compensation, termination, change in control and other arrangements, which are described under “Executive Compensation” and “Director Compensation.”
Indemnification Agreements
We have entered into indemnification agreements with each of our current directors and executive officers.
Householding of Proxy Materials
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other annual meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other annual meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.
This year, a number of brokers with account holders who are Company stockholders will be “householding” the Company’s proxy materials. A single Notice of Internet Availability of Proxy Materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate Notice of Internet Availability of Proxy Materials, please notify your broker or the Company. Direct your written request to Kronos Bio, Inc., Secretary, 1300 So. El Camino Real, Suite 400, San Mateo, California 94402, or call us at (650) 781-5200. Stockholders who currently receive multiple copies of the Notices of Internet Availability of Proxy Materials at their addresses and would like to request “householding” of their communications should contact their brokers.
