NOTICE OF 2023 ANNUAL MEETING OF STOCKHOLDERS

To be held online on May 16, 2023 at www.virtualshareholdermeeting.com/BDTX2023

Notice is hereby given that the 2023 Annual Meeting of Stockholders, or the Annual Meeting, of Black Diamond Therapeutics, Inc., will be held online on May 16, 2023 at 9:00 a.m. Eastern Time. In light of continuing public health concerns resulting from the ongoing COVID-19 pandemic, and to support the health and well-being of our stockholders, employees and communities, the Annual Meeting will again be held as a virtual meeting, which will be conducted via live webcast. You may attend the meeting online, vote your shares electronically and submit questions by visiting www.virtualshareholdermeeting.com/BDTX2023.

The purpose of the Annual Meeting is the following:

To elect three Class III director nominees to our board of directors, to serve until the Company’s 2026 annual meeting of stockholders and until his or her successor has been duly elected and qualified, or until his or her earlier death, resignation or removal;

To ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023; and

To transact any other business properly brought before the Annual Meeting or any adjournment or postponement of the Annual Meeting.

Only Black Diamond Therapeutics, Inc. stockholders of record at the close of business on March 20, 2023, the record date for the Annual Meeting, are entitled to notice of, and to vote at, the Annual Meeting or any adjournment or postponement of the Annual Meeting.

You can find more information on each of the matters to be voted on at the Annual Meeting, including information regarding the nominees for election to our board of directors, in the accompanying proxy statement. The board of directors recommends a vote “FOR” the election of the three nominees for Class III directors and “FOR” the ratification of the appointment of our independent registered public accounting firm for the fiscal year ending December 31, 2023, as disclosed in the accompanying proxy statement.

We are pleased to take advantage of the rules of the Securities and Exchange Commission, or the SEC, that allow companies to distribute their proxy materials over the Internet under the “notice and access” approach. As a result, we are mailing to our stockholders a Notice of Internet Availability of Proxy Materials, or Notice of Availability, instead of a paper copy of our proxy materials and our Annual Report to Stockholders for the fiscal year ended December 31, 2022, or the 2022 Annual Report. We will mail the Notice of Availability on or about April 4, 2023, and it contains instructions on how to access those documents and to cast your vote via the Internet or by telephone. This process allows us to provide our stockholders with the information they need on a more timely basis, while reducing the environmental impact and lowering the costs of printing and distributing our proxy materials. If you would like to receive a printed copy of our proxy materials, including our proxy statement, our 2022 Annual Report and a form of proxy card, free of charge, please follow the instructions on the Notice of Availability.

Please see the “General Information” section of the proxy statement that accompanies this notice for more details regarding the logistics of the virtual Annual Meeting, including the ability of stockholders to submit questions during the Annual Meeting, and technical details and support related to accessing the virtual platform. You will not be able to attend the Annual Meeting in person.

To support the health and well-being of our stockholders, employees and communities, the Annual Meeting will again be a virtual meeting, which will be conducted via live webcast. You may attend the meeting online, vote your shares electronically and submit questions by visiting www.virtualshareholdermeeting.com/BDTX2023. The board of directors of Black Diamond Therapeutics, Inc. is using this proxy statement to solicit proxies for use at the Annual Meeting. In this proxy statement, the terms “Black Diamond Therapeutics,” “Black Diamond,” the “Company,” “we,” “us,” “our,” and similar designations refer to Black Diamond Therapeutics, Inc. and, where appropriate, our subsidiaries. The mailing address of our principal executive office is Black Diamond Therapeutics, Inc., One Main Street, 14th Floor, Cambridge, MA 02142.

Please see the “General Information” section of the proxy statement for more details regarding the logistics of the virtual Annual Meeting, including the ability of stockholders to submit questions during the Annual Meeting, and technical details and support related to accessing the virtual platform. You will not be able to attend the 2023 Annual Meeting in person.

All properly submitted proxies will be voted in accordance with the instructions contained in those proxies. If no instructions are specified, the proxies will be voted in accordance with the recommendation of our board of directors with respect to each of the matters set forth in the accompanying Notice of Meeting. You may revoke your proxy at any time before it is exercised at the meeting by giving our Corporate Secretary written notice to that effect.

We made this proxy statement and our Annual Report to Stockholders for the fiscal year ended December 31, 2022, or the 2022 Annual Report, available to stockholders on or about April 4, 2023.

We are an “emerging growth company” under applicable federal securities laws and therefore permitted to conform with certain reduced public company reporting requirements. As an emerging growth company, we provide in this proxy statement the scaled disclosure permitted under the Jumpstart Our Business Startups Act of 2012, including the compensation disclosures required of a “smaller reporting company,” as that term is defined in Rule 12b-2 promulgated under the Securities Exchange Act of 1934, as amended, or the Exchange Act. In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted. We will remain an “emerging growth company” until the earliest of (i) the last day of the fiscal year following the fifth anniversary of our initial public offering in February 2020; (ii) the last day of the fiscal year in which our total annual gross revenue is equal to or more than $1.235 billion; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the Securities and Exchange Commission, or the SEC.

PROXY STATEMENT
FOR THE 2023 ANNUAL MEETING OF STOCKHOLDERS
GENERAL INFORMATION

When are this proxy statement and the accompanying materials scheduled to be sent to stockholders?

We have elected to provide access to our proxy materials to our stockholders via the Internet. Accordingly, on or about April 4, 2023, we will begin mailing the Notice of Availability. Our proxy materials, including the Notice of the 2023 Annual Meeting of Stockholders, this proxy statement and the accompanying proxy card or, for shares held in “street name” (i.e., held for your account by a broker, bank or other nominee), a voting instruction form, and the 2022 Annual Report to Stockholders, or the 2022 Annual Report, will be mailed or made available to stockholders on the Internet on or about the same date.

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

Pursuant to rules adopted by the SEC, we are providing access to our proxy materials over the Internet rather than printing and mailing our proxy materials. We believe electronic delivery will expedite the receipt of such materials and will help lower our costs and reduce the environmental impact of our proxy materials. Therefore, the Notice of Availability was mailed to holders of record and beneficial owners of our common stock starting on or about April 4, 2023. The Notice of Availability provides instructions as to how stockholders may access and review our proxy materials, including the Notice of the 2023 Annual Meeting of Stockholders, this proxy statement, the proxy card and our 2022 Annual Report, on the website referred to in the Notice of Availability or, alternatively, how to request that a printed copy of the proxy materials, including a proxy card, be sent to them by mail. The Notice of Availability also provides voting instructions. In addition, stockholders of record may request to receive the proxy materials in printed form by mail, or electronically by e-mail, on an ongoing basis for future stockholder meetings. Please note that, while our proxy materials are available at the website referenced in the Notice of Availability and our Notice of the 2023 Annual Meeting of Stockholders, this proxy statement and our 2022 Annual Report are available on our website, no other information contained on either website is incorporated by reference in, or considered to be a part of, this proxy statement.

Who is soliciting my vote?

Our board of directors is soliciting your vote for the Annual Meeting.

When is the record date for the Annual Meeting?

The record date for determination of stockholders entitled to vote at the Annual Meeting is the close of business on March 20, 2023.

How many votes can be cast by all stockholders?

There were 36,504,836 shares of our common stock, par value $0.0001 per share, outstanding on March 20, 2023, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting. Each stockholder of record is entitled to one vote for each share of our common stock held by such stockholder.

How do I vote?

If you are a stockholder of record, there are several ways for you to vote your shares.

•

By Internet (before the Annual Meeting). You may vote at www.proxyvote.com, 24 hours a day, seven days a week, by following the instructions at that site for submitting your proxy electronically. You will be required to enter the 16-digit control number provided in the Notice of Availability or the proxy card. Votes submitted through the Internet must be received by 11:59 p.m. Eastern Time on May 15, 2023.

•

By Telephone. You may vote using a touch-tone telephone by calling 1-800-690-6903 (toll-free from the U.S., U.S. territories and Canada), 24 hours a day, seven days a week. You will be required to

TABLE OF CONTENTS

provide the 16-digit control number provided in the Notice of Availability or the proxy card. Votes submitted by telephone must be received by 11:59 p.m. Eastern Time on May 15, 2023.

•

By Mail. If you requested and received a printed copy of the proxy materials, you may vote by mail by completing, signing and dating the enclosed proxy card and returning it in the enclosed prepaid envelope. Votes submitted through the mail must be received prior to May 16, 2023.

•

During the Annual Meeting. If you are a stockholder of record as of the record date, you may vote during the live webcast of the Annual Meeting by visiting www.virtualshareholdermeeting.com/BDTX2023. You will be required to enter the 16-digit control number provided in the Notice of Availability or the proxy card. Submitting a proxy prior to the Annual Meeting will not prevent stockholders from attending the Annual Meeting, revoking their earlier-submitted proxy, and voting at the Annual Meeting.

If the Annual Meeting is adjourned or postponed, the deadlines above may be extended.

If you are a beneficial owner of shares held in “street name” by your broker, bank or other nominee, you should have received a voting instruction form with these proxy materials from your broker, bank or other nominee rather than from us. The voting deadlines and availability of telephone and Internet voting for beneficial owners of shares will depend on the voting processes of the broker, bank or other nominee that holds your shares. Therefore, we urge you to carefully review and follow the voting instruction form and any other materials that you receive from that organization. If you hold your shares in multiple accounts, you should vote your shares as described in each set of proxy materials you receive.

If you submit a proxy without giving voting instructions, your shares will be voted in the manner recommended by the board of directors on all matters presented in this proxy statement, and as the persons named as proxies in the proxy card may determine in their discretion with respect to any other matters properly presented at the Annual Meeting. You may also authorize another person or persons to act for you as proxy in a writing, signed by you or your authorized representative, specifying the details of those proxies’ authority. The original writing must be given to each of the named proxies, although it may be sent to them by electronic transmission if, from that transmission, it can be determined that the transmission was authorized by you.

If any other matters are properly presented for consideration at the Annual Meeting, including, among other things, consideration of a motion to adjourn the Annual Meeting to another time or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named in your proxy and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. We do not currently anticipate that any other matters will be raised at the Annual Meeting.

How can I virtually attend the Annual Meeting?

This year’s Annual Meeting will be held entirely online to support the health and well-being of our stockholders, employees and communities. Stockholders of record as of March 20, 2023 will be able to attend and participate in the Annual Meeting online by accessing www.virtualshareholdermeeting.com/BDTX2023.

To join the Annual Meeting, you will need to have your 16-digit control number, which is provided in the Notice of Availability or the proxy card. If your shares are held in “street name” through a broker, bank or other nominee and you do not have a 16-digit control number, you must contact such broker, bank or nominee in order to gain access to the meeting.

Access to the Live Webcast of the Annual Meeting

The live webcast of the Annual Meeting will begin promptly at 9:00 a.m. Eastern Time on May 16, 2023. Online access to the webcast will open approximately fifteen (15) minutes prior to the start of the Annual Meeting to allow time for you to log in and test the computer audio system. We encourage stockholders to log in to this website and access the webcast before the Annual Meeting’s start time. You should allow ample time in advance of the meeting.

TABLE OF CONTENTS

Submitting Questions at the Annual Meeting

During the Annual Meeting, if you have your 16-digit control number and wish to ask a question, you may do so by clicking the Q&A button on the virtual meeting platform and entering your question in the field provided in the web portal at or before the time the matters are before the Annual Meeting for consideration. During the formal portion of the meeting, all questions presented should relate directly to the proposal under discussion, which will be answered before the voting is closed. We will also hold a question and answer period at the end of the meeting, as time permits, during which time we welcome questions not relating to specific proposals. To allow us to answer questions from as many stockholders as possible, we will limit each stockholder to two questions. Questions from multiple stockholders on the same topic or that are otherwise related to a particular topic may be grouped, summarized and answered together. If questions submitted are irrelevant to the business of the Annual Meeting or are out of order or not otherwise suitable for the conduct of the Annual Meeting as determined by the Chair or Corporate Secretary in their reasonable judgment, we may choose not to address them. If there are any matters of individual concern to a stockholder and not of general concern to all stockholders, or if a question posed was not otherwise answered, such matters may be raised separately after the Annual Meeting. Following the meeting, we will post questions received during the meeting, and our responses thereto, on the Investors & News section of our website. If we received questions that were repetitive as to a particular topic, we may combine our answers to those questions into one answer on our website.

Our Annual Meeting will be governed by the Annual Meeting’s Rules of Conduct, which will address the ability of stockholders to ask questions during the meeting and include rules for how questions will be recognized and addressed. Please review the Annual Meeting’s Rules of Conduct for further details. The Annual Meeting’s Rules of Conduct are available at www.proxyvote.com and during the Annual Meeting at www.virtualshareholdermeeting.com/BDTX2023.

Annual Meeting Technical Assistance

Beginning 15 minutes prior to the start of and during the Annual Meeting, we will have a support team ready to assist stockholders with any technical difficulties they may have accessing or hearing the virtual meeting. If you encounter any 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 shareholder meeting log-in page.

How do I revoke my proxy?

If you are a stockholder of record, you may revoke your proxy by (1) following the instructions on the Notice of Availability and submitting a new vote by Internet, telephone or mail using the procedures described in the “How do I Vote?” section above before the applicable deadline, (2) attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not in and of itself revoke a proxy), or (3) by filing an instrument in writing revoking the proxy or submitting another duly executed proxy card bearing a later date with our Corporate Secretary. Any written notice of revocation or subsequent proxy card must be received by our Corporate Secretary prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be hand delivered to our Corporate Secretary or sent to our principal executive offices at Black Diamond Therapeutics, Inc., One Main Street, 14th Floor, Cambridge, MA 02142, Attention: Corporate Secretary.

If a broker, bank, or other nominee holds your shares, you must contact such broker, bank, or nominee in order to find out how to change your vote.

How is a quorum reached?

Our Amended and Restated Bylaws, or bylaws, provide that a majority of the outstanding shares entitled to vote, present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting. Shares present virtually during the Annual Meeting will be considered shares of common stock represented in person at the meeting.

Under the General Corporation Law of the State of Delaware, shares that are voted “abstain” or “withheld” and broker “non-votes” are counted as present for purposes of determining whether a quorum is present at the Annual Meeting. If a quorum is not present, the meeting may be adjourned until a quorum is obtained.

TABLE OF CONTENTS

How is the vote counted?

Under our bylaws, any proposal other than an election of directors is decided by a majority of the votes properly cast for and against such proposal, except where a larger vote is required by law, our Fourth Amended and Restated Certificate of Incorporation, or certificate of incorporation, or our bylaws. Abstentions and broker “non-votes” are not included in the tabulation of the voting results on any such proposal and, therefore, do not have an impact on such proposals. A broker “non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item, and has not received instructions from the beneficial owner.

If your shares are held in “street name” by a broker, bank or other nominee, your broker, bank or other nominee is required to vote your shares according to your instructions. If you do not give instructions to your broker, bank or other nominee, the broker, bank or other nominee will still be able to vote your shares with respect to certain “discretionary” items, but will not be allowed to vote your shares with respect to “non-discretionary” items. Proposal No. 1 is a “non-discretionary” item. If you do not instruct your broker how to vote with respect to this proposal, your broker, bank or other nominee may not vote for this proposal, and those votes will be counted as broker “non-votes.” Proposal No. 2 is considered to be a discretionary item, and your broker, bank or other nominee will be able to vote on this proposal even if it does not receive instructions from you.

What vote is required to adopt each proposal?

Each share of our common stock outstanding on the record date is entitled to one vote on any proposal presented at the Annual Meeting.

For Proposal No. 1, the election of directors, the nominees must receive a plurality of the votes properly cast on the proposal, meaning that the three director nominees receiving the most votes will be elected. Shares voting “withheld” and broker non-votes will have no effect on the outcome of Proposal No. 1.

For Proposal No. 2, a majority of the votes properly cast is required to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023. Abstentions and broker non-votes will have no effect on the outcome of Proposal No. 2.

Who pays the cost for soliciting proxies?

We are making this solicitation and will pay the entire cost of preparing and distributing the Notice of Availability and our proxy materials and soliciting votes. If you choose to access the proxy materials or vote over the Internet or by telephone, you are responsible for any Internet access or telephone charges that you may incur. Our officers and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, e-mails, or otherwise. We will also reimburse brokers, banks, custodians, other nominees, and fiduciaries for forwarding these materials to their principals to obtain the authorization for the execution of proxies.

How may stockholders submit matters for consideration at an annual meeting?

The required notice must be in writing and received by our Corporate Secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting. However, in the event that the date of the annual meeting is convened more than 30 days before or more than 60 days after the first anniversary of the preceding year’s annual meeting, or if no annual meeting were held in the preceding year, a stockholder’s notice must be so received not later than the close of business on the later of (i) the 90th day prior to the scheduled date of such annual meeting or (ii) the 10th day following the day on which public announcement of the date of such annual meeting was first made.

In addition, any stockholder proposal intended to be included in the proxy statement for the next annual meeting of our stockholders in 2024 must also satisfy the requirements of SEC Rule 14a-8 under the Exchange Act, and be received not later than December 8, 2023. If the date of the annual meeting is moved by more than 30 days from the date contemplated at the time of the previous year’s proxy statement,

TABLE OF CONTENTS

PROPOSAL NO. 1 — ELECTION OF CLASS III DIRECTORS

Our board of directors currently consists of nine members. In accordance with the terms of our certificate of incorporation and bylaws, our board of directors is divided into three classes, Class I, Class II and Class III, with members of each class serving staggered three-year terms. The members of the classes are divided as follows:

•

the Class I directors are Alexander Mayweg, Rajeev Shah and Mark A. Velleca, and their terms will expire at the annual meeting of stockholders to be held in 2024;

•

the Class II directors are Ali Behbahani, Garry E. Menzel and Samarth Kulkarni, and their terms will expire at the annual meeting of stockholders to be held in 2025; and

•

the Class III directors are David M. Epstein, Wendy L. Dixon and Kapil Dhingra, and their terms will expire at the Annual Meeting.

Upon the expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires.

Our certificate of incorporation and bylaws provide that the authorized number of directors may be fixed from time to time by resolution of the majority of our board of directors. Our certificate of incorporation provides that our directors may be removed only for cause by the affirmative vote of the holders of at least two-thirds (2/3) of the outstanding shares then entitled to vote at an annual election of directors, and that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office.

Our board of directors has nominated David M. Epstein, Wendy L. Dixon and Kapil Dhingra for election as the Class III directors at the Annual Meeting. The nominees are presently directors, and each has indicated a willingness to continue to serve as a director, if elected. If the nominees become unable or unwilling to serve, however, the proxies may be voted for a substitute nominee selected by our board of directors.

Vote Required and Board of Directors’ Recommendation

To be elected, the directors nominated via Proposal No. 1 must receive a plurality of the votes properly cast on the proposal, meaning that the three director nominees for Class III directors receiving the most votes

TABLE OF CONTENTS

will be elected. You may vote FOR all the nominees, FOR any one of the nominees, WITHHOLD your vote from all the nominees or WITHHOLD your vote from any one of the nominees. Votes that are withheld will not be included in the vote tally for the election of directors. If your shares are held in “street name” by a broker, bank or other nominee, your broker, bank or other nominee does not have authority to vote your unvoted shares held by the firm for the election of directors. As a result, any shares not voted by you will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote.

The proxies will be voted in favor of the above nominees unless a contrary specification is made in the proxy. The nominees have consented to serve as our directors if elected. However, if the nominees are unable to serve or for good cause will not serve as a director, the proxies will be voted for the election of such substitute nominee as our board of directors may designate.

The proposal for the election of directors relates solely to the election of Class III directors nominated by our board of directors.

The board of directors recommends voting “FOR” the election of David M. Epstein, Wendy L. Dixon and Kapil Dhingra, as the Class III directors, to serve for a three-year term ending at the annual meeting
of stockholders to be held in 2026.

However, the board of directors believes that submitting the appointment of PwC to the stockholders for ratification is good corporate governance. If the stockholders do not ratify this appointment, the audit committee will reconsider whether to retain PwC. If the selection of PwC is ratified, the audit committee, at its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of Black Diamond Therapeutics and its stockholders.

A representative of PwC is expected to virtually attend the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders.

CORPORATE GOVERNANCE

Director Nomination Process

Our nominating and corporate governance committee is responsible for identifying individuals qualified to serve as directors, consistent with criteria approved by our board of directors, and recommending such persons to be nominated for election as directors, except where we are legally required by contract, law or otherwise to provide third parties with the right to nominate.

The process followed by our nominating and corporate governance committee to identify and evaluate director candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates, and interviews of selected candidates by management, recruiters, members of the committee and our board. The qualifications, qualities and skills that our nominating and corporate governance committee believes must be met by a committee-recommended nominee for a position on our board of directors are as follows:

•

Nominees should demonstrate high standards of personal and professional ethics and integrity.

•

Nominees should have proven achievement and competence in the nominee’s field and the ability to exercise sound business judgment.

•

Nominees should have skills that are complementary to those of the existing board.

•

Nominees should have the education, expertise and business acumen to assist and support management and make significant contributions to the Company’s success.

•

Nominees should have an understanding of the fiduciary responsibilities that are required of a member of the board of directors and the commitment of time and energy necessary to diligently carry out those responsibilities.

Stockholders may recommend individuals to the nominating and corporate governance committee for consideration as potential director candidates. Any such proposals should be submitted to our Corporate Secretary at our principal executive offices no later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the one-year anniversary of the date of the preceding year’s annual meeting and should include appropriate biographical and background material to allow the nominating and corporate governance committee to properly evaluate the potential director candidate and the number of shares of our stock beneficially owned by the stockholder proposing the candidate. Stockholder proposals should be addressed to Black Diamond Therapeutics, Inc., One Main Street, 14th Floor, Cambridge, MA 02142, Attention: Corporate Secretary. Assuming that biographical and background materials have been provided on a timely basis in accordance with our bylaws, any recommendations received from stockholders will be evaluated in the same manner as potential nominees proposed by the nominating and corporate governance committee. If our board of directors determines to nominate a stockholder-recommended candidate and recommends such candidate’s election, then such candidate’s name will be included on our proxy card for the next annual meeting of stockholders. See “Stockholder Proposals” for a discussion of submitting stockholder proposals.

Director Independence

Our common stock was approved for listing on The Nasdaq Global Select Market. Under the Nasdaq listing rules, independent directors must comprise a majority of a listed company’s board of directors within twelve months from the date of listing. In addition, the Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent and that audit committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act and that nominating and corporate governance committee members satisfy independence criteria set forth in Rule 10C-1 under the Exchange Act. Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of the listed company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3 under the Exchange Act, a member of an audit committee of a listed company may not,

TABLE OF CONTENTS

other than in such member’s capacity as a member of the audit committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries, other than compensation for board service; or (2) be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C-1, the board of directors consider, for each member of a nominating and corporate governance committee of a listed company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a nominating and corporate governance committee member, including, but not limited to: the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director, and whether the director is affiliated with the company or any of its subsidiaries or affiliates.

Our board of directors has determined that all members of the board of directors, except David M. Epstein and Alexander Mayweg, are independent directors, including for purposes of the rules of Nasdaq and the SEC. In making such independence determination, our board of directors considered the relationships that each director has with us 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 director. In considering the independence of the directors listed above, our board of directors considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors or executive officers.

Director Diversity

Our Amended and Restated Nomination and Corporate Governance Committee Policies and Procedures for Director Candidates, or the Director Guidelines, provide that the value of diversity should be considered in determining director candidates as well as other factors such as a candidate’s character, judgment, skills, education, expertise and absence of conflicts of interest. Our priority in selection of board members is identification of members who will further the interests of our stockholders through their established records of professional accomplishment, their ability to contribute positively to the collaborative culture among board members, and their knowledge of our business and understanding of the competitive landscape in which we operate and adherence to high ethical standards. While our Director Guidelines do not specify assigned weights to particular criteria, our board of directors and nominating and corporate governance committee believe it is essential that members of our board of directors represent diverse viewpoints and that the backgrounds and qualifications of our directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will allow our board to promote our strategic objectives and fulfill its responsibilities to our stockholders. In particular, diversity in terms of race, ethnicity, age, and gender is viewed as important, in addition to many other factors, including industry knowledge, operational experience, scientific and academic expertise and personal backgrounds. Under the recently approved Nasdaq listing rule, directors who self-identify as (i) female, (ii) an underrepresented minority, or (iii) LGBTQ+ are defined as being diverse.

In addition to each of the nominees and continuing directors’ specific experience, qualifications, attributes and skills that our board of directors and our nominating and corporate governance committee considered in determining that he or she should serve as a director, we also believe that each of our directors has demonstrated business acumen, integrity and an ability to exercise sound judgment, as well as a commitment of service to the Company and our board of directors.

The following Board Diversity Matrix presents our board of directors’ diversity statistics in accordance with Nasdaq Rule 5606, as self-disclosed by our directors. Our board of directors satisfies the minimum objectives of Nasdaq Rule 5605(f)(3) by having at least one director who identifies as female and at least one director who identifies as a member of an Underrepresented Minority (as defined by Nasdaq Rules). As we pursue future recruitment efforts for our board of directors and the board’s composition continues to evolve following the Company’s initial public offering in 2020, our nominating and corporate governance committee will continue to seek out candidates who can contribute to the diversity of views and perspectives of the board of directors. In particular, we intend to prioritize opportunities for the appointment of qualified candidates to increase further gender diversity on our board of directors by the date of our next annual meeting. For more information on our director nomination process, please see “— Director Nomination Process”.

Board Committees

In April 2022, our board of directors reconstituted its board committee structure from a two-committee structure, consisting of an audit committee and a compensation, nomination and corporate governance committee to a three-committee structure, consisting of an audit committee, a compensation committee, and a nominating and corporate governance committee. In connection therewith, our board of directors also approved reconstituted charters for each of the committees consistent with the committee changes made. Each of the audit committee, compensation committee, and nominating and corporate governance committee operates under a charter that satisfies the applicable standards of the SEC and Nasdaq. Each such committee reviews its respective charter at least annually. A current copy of the charter for each of the committees is posted on the corporate governance section of our website.

Compensation Committee

Mark A. Velleca, Ali Behbahani and Garry E. Menzel serve on the compensation committee, which is chaired by Mark A. Velleca. Our board of directors has determined that each member of the compensation committee is “independent” as defined in the applicable Nasdaq rules. In 2022, we reconstituted our committees and separated our compensation, nomination and corporate governance committee into a compensation committee and a nominating and corporate governance committee. During the fiscal year ended December 31, 2022, the compensation committee met two (2) times as the former compensation, nomination and corporate governance committee, and two (2) times as the existing compensation committee. The compensation committee’s responsibilities include:

•

annually reviewing and recommending to the board of directors the corporate goals and objectives relevant to the compensation of our Chief Executive Officer;

•

evaluating the performance of our Chief Executive Officer in light of such corporate goals and objectives and, based on such evaluation, (i) recommending to the board of directors the cash compensation of our Chief Executive Officer and (ii) reviewing and recommending to the board of directors any grants and awards to our Chief Executive Officer under equity-based plans;

•

reviewing and approving the compensation of our other executive officers;

•

reviewing and establishing our overall management compensation philosophy and policy;

TABLE OF CONTENTS

•

overseeing and administering our compensation and similar plans;

•

evaluating and assessing potential and current compensation advisors in accordance with the independence standards identified in the applicable Nasdaq listing rules;

•

reviewing and approving our policies and procedures for the grant of equity-based awards;

•

reviewing and recommending to the board of directors the compensation of our directors;

•

reviewing and discussing annually with management our “Compensation Discussion and Analysis,” if and when required, to be included in our annual proxy statement;

•

preparing our compensation committee report if and when required by the SEC rules to be included in our annual proxy statement; and

•

reviewing and approving the retention or termination of any consulting firm or outside advisor to assist in the evaluation of compensation matters.

The compensation committee may delegate its authority to grant certain equity awards to one or more officers of the Company, including our Chief Executive Officer, and in 2021 it delegated such authority to our Chief Executive Officer and our Chief Operating Officer and General Counsel.

Aon Consulting, Inc. (Aon) has served as our independent compensation consultant since 2019. Aon reports directly to the compensation committee, and the compensation committee has the sole authority to hire, fire and direct the work of Aon. Aon provides various executive compensation services to the compensation committee, including an analysis of executive compensation as relates to base salary, target annual cash incentives and long-term equity incentives for executive officers and advice on evolving industry practices and market information. As part of its engagement, Aon assists our compensation committee 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. Aon also provides the compensation committee with advice and analysis regarding compensation of non-employee directors. The compensation committee has assessed the independence of Aon pursuant to SEC and Nasdaq rules and concluded that the work of Aon for the compensation committee does not raise any conflict of interest.

Nominating and Corporate Governance Committee

Wendy L. Dixon, Kapil Dhingra and Samarth Kulkarni serve on the nominating and corporate governance committee, which is chaired by Wendy L. Dixon. Our board of directors has determined that each member of the nominating and corporate governance committee is “independent” as defined in the applicable Nasdaq rules. The nominating and corporate governance committee became a stand-alone committee in April 2022. During the fiscal year ended December 31, 2022, the former compensation, nomination and corporate governance committee met two (2) times and the existing nominating and corporate governance committee met two (2) times. Prior to becoming a stand-alone committee, matters related to nominating and corporate governance were among the responsibilities of the compensation committee. The nominating and corporate governance committee’s responsibilities include:

•

reviewing and advising management regarding the company’s human capital management strategies, including culture, diversity and inclusion strategies, programs and initiatives;

•

developing and recommending to the board of directors criteria for board and committee membership;

•

establishing procedures for identifying and evaluating board of director candidates, including nominees recommended by stockholders;

•

reviewing the composition of the board of directors to ensure that it is composed of members containing the appropriate skills and expertise to advise us;

•

identifying individuals qualified to become members of the board of directors;

•

recommending to the board of directors the persons to be nominated for election as directors and to each of the board’s committees;

TABLE OF CONTENTS

•

developing and recommending to the board of directors a code of business conduct and ethics and a set of corporate governance guidelines;

•

reviewing and overseeing the company’s environmental, social and governance, or ESG, strategy, initiatives, and policies, including matters related to environmental, health and safety, diversity and inclusion, and ethics and compliance programs; and

•

overseeing the evaluation of our board of directors and management.

The nominating and corporate governance committee considers candidates for board of director membership suggested by its members and our Chief Executive Officer. Additionally, in selecting nominees for directors, the nominating and corporate governance committee will review candidates recommended by stockholders in the same manner and using the same general criteria as candidates recruited by the committee and/or recommended by our board of directors. Any stockholder who wishes to recommend a candidate for consideration by the committee as a nominee for director should follow the procedures described later in this proxy statement under the heading “Stockholder Proposals.” The nominating and corporate governance committee will also consider whether to nominate any person proposed by a stockholder in accordance with the provisions of our bylaws relating to stockholder nominations as described later in this proxy statement under the heading “Stockholder Proposals.”

We believe that the composition and functioning of our nominating and corporate governance committee complies 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.

Our board of directors may from time to time establish other committees.

Identifying and Evaluating Director Nominees.

Our board of directors is responsible for filling vacancies on our board of directors and for nominating candidates for election by our stockholders each year in the class of directors whose term expires at the relevant annual meeting. The board of directors delegates the selection and nomination process to the nominating and corporate governance committee, with the expectation that other members of the board of directors, and of management, will be requested to take part in the process as appropriate.

Generally, the nominating and corporate governance committee identifies candidates for director nominees in consultation with management, through the use of search firms or other advisors, through the recommendations submitted by stockholders or through such other methods as the nominating and corporate governance committee deems to be helpful to identify candidates. Once candidates have been identified, the nominating and corporate governance committee confirms that the candidates meet all of the minimum qualifications for director nominees established by nominating and corporate governance committee. The nominating and corporate governance committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the nominating and corporate governance committee deems to be appropriate in the evaluation process. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition, needs and diversity of our board of directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the board of directors’ approval to fill a vacancy or as director nominees for election to the board of directors by our stockholders each year in the class of directors whose term expires at the relevant annual meeting.

Minimum Qualifications for Director Nominees.

Our nominating and corporate governance committee and our board of directors consider a broad range of factors relating to the qualifications of nominees. Our nominating and corporate governance committee’s and our board of directors’ priority in selecting board members is the identification of persons who will provide a composite mix of backgrounds, experience, knowledge and capabilities that will allow our board to promote our strategic objectives and fulfill its responsibilities to our stockholders. Our nominating and corporate governance committee and our board of directors highly value diversity and, as

TABLE OF CONTENTS

such, also consider diversity of gender, race, ethnicity, age, gender identity, gender expression and sexual orientation when selecting members of our board of directors.

Board and Committee Meetings Attendance

The full board of directors met six (6) times during fiscal year 2022. Each incumbent director attended in person or participated via teleconference in 75% or more of the aggregate of (i) the total number of meetings of the board of directors (held during the period for which such person has been a director), and (ii) the total number of meetings held by all committees of the board of directors on which such person served (during the periods that such person served).

Director Attendance at Annual Meeting of Stockholders

Directors are responsible for attending the annual meeting of stockholders to the extent practicable. The Company encourages its directors to attend the annual meeting of stockholders. We held an annual meeting of stockholders on June 7, 2022, at which five directors were present.

Policy on Trading, Pledging and Hedging of Company Stock

Certain transactions in our securities (such as purchases and sales of publicly traded put and call options, and short sales) create a heightened compliance risk or could create the appearance of misalignment between management and stockholders. In addition, securities held in a margin account or pledged as collateral may be sold without consent if the owner fails to meet a margin call or defaults on the loan, thus creating the risk that a sale may occur at a time when an officer or director is aware of material, non-public information or otherwise is not permitted to trade in Company securities. Our amended and restated insider trading policy expressly prohibits derivative transactions of our stock by our executive officers, directors and employees. In addition, our amended and restated insider trading policy also expressly prohibits purchases of any derivative securities that provide the economic equivalent of ownership.

Rule 10b5-1 Trading Plan Policy

We have adopted a Rule 10b5-1 trading plan policy, which permits our officers, directors, and certain other persons to enter into trading plans complying with Rule 10b5-1 under the Exchange Act. Generally, under these trading plans, the individual relinquishes control over the transactions once the trading plan is put into place and can only put such plans into place while the individual is not in possession of material non-public information. Accordingly, sales under these plans may occur at any time, including possibly before, simultaneously with, or immediately after significant events involving our company.

Environmental, Social and Governance

A continued area of focus for our board of directors has been our ESG-related practices which are integrated into our business strategy and planning including product safety, human capital management, and ethics and compliance. These are among the areas of focus that are critical to our long-term success and resiliency. We are therefore committed to increasing our transparency and further identifying issues that may have a material effect on corporate strategy, risks, opportunities or performance.

Human Capital Management. As of February 15, 2023, we had 65 full-time employees. Our workforce is highly skilled, with 22 of our employees holding an M.D., Ph.D. or Pharm.D. degree. Of our full-time employees, 43 were engaged in research and development activities. We consider our relationship with our employees to be good and our future success depends on our ability to attract, develop and retain key personnel, maintain our culture, and ensure diversity and inclusion in our board, management and broader workforce. As these areas directly impact our ability to compete and innovate, they are key focus areas for our board of directors and senior executives. The biopharmaceutical industry is highly competitive and recruiting and retaining employees is critical to the continued success of our business. To attract, maintain and motivate our team of high achieving professionals, we offer competitive compensation and benefits, a collaborative work environment, ongoing professional development initiatives, attractive career advancement opportunities and a culture that highly values diversity, equity and inclusion (DE&I). We are committed to being an equal opportunity employer and continuously strive to enhance awareness and understanding

TABLE OF CONTENTS

regarding DE&I issues. Our employees are motivated by our mission to expand the reach of precision oncology medicine through the development of novel MasterKey therapies.

Ethics and Compliance. We continue to strengthen corporate compliance through our commitment to honest and ethical conduct and with clear oversight and accountability from senior executives and directors. Our internal policies are based on industry-standard principles for behavior in this area. This also includes our Code of Business Conduct and Ethics, which outlines our commitment to ethical business practices and applies to all of our employees, officers and directors.

Health and Safety. The success of our business is fundamentally connected to the well-being of our employees. Accordingly, we are committed to their health, safety and wellness. We provide our employees and their families with access to a variety of innovative, flexible and convenient health and wellness programs, including benefits that provide protection and security so they can have peace of mind concerning events that may require time away from work or that impact their financial well-being; that support their physical and mental health by providing tools and resources to help them improve or maintain their health status and encourage engagement in healthy behaviors; and that offer choice where possible so they can customize their benefits to meet their needs and the needs of their families. In response to the ongoing COVID-19 pandemic, we implemented necessary changes that we determined were in the best interest of our employees, as well as the communities in which we operate, and which comply with government regulations. This includes enhanced safety measures for our lab-based employees working on-site, and hybrid work arrangements for our office-based employees.

Code of Business Conduct and Ethics

We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A current copy of the code is posted on the corporate governance section of our website, which is located at https://investors.blackdiamondtherapeutics.com/corporate-governance/governance-documents. If we make any substantive amendments to, or grant any waivers from, the code of business conduct and ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a Current Report on Form 8-K.

Environmental

We are committed to minimizing the environmental impacts of our business. We encourage all employees to reduce waste and emissions through recycling and other energy conservation measures. The following are a few of the initiatives that demonstrate our commitment to environmental impact:

•

We are subject to numerous environmental, health and safety laws and regulations.

•

Our employees are required to promptly report any known or suspected violations of environmental laws or any events that may result in a discharge or emission of hazardous materials.

•

We have recycling in all facilities.

•

We minimize use of disposable bottles and printing of paper.

•

We have commuter benefits programs in place that encourage employees to walk, bike or utilize public transportation instead of cars for their commute.

•

We encourage video conferencing for non-essential meetings to reduce travel and commute emissions.

Board Leadership Structure and Board’s Role in Risk Oversight

Currently, the role of chair of the board is separated from the role of Chief Executive Officer, and we plan to keep these roles separate. We believe that separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the chair of the board to lead the board of directors in its fundamental role of providing advice to, and independent oversight of, management. Our board of directors recognizes the time, effort, and energy that the Chief Executive Officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our chair,

TABLE OF CONTENTS

particularly as the board of directors’ oversight responsibilities continue to grow. While our bylaws and our corporate governance guidelines do not require that our chair and Chief Executive Officer positions be separate, our board of directors believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.

Risk is inherent to every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and commercialization activities, operations, strategic direction and intellectual property. Management is responsible for the day-to-day management of risks we face, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

The role of the board of directors in overseeing the management of our risks is conducted primarily through committees of the board of directors, as disclosed in the descriptions of each of the committees above and in the charters of each of the committees. The full board of directors (or the appropriate board committee in the case of risks that are under the purview of a particular committee) discusses with management our major risk exposures, their potential impact on us, and the steps we take to manage them. When a board committee is responsible for evaluating and overseeing the management of a particular risk or risks, the chair of the relevant committee reports on the discussion to the full board of directors during the committee reports portion of the next board meeting. This enables the board of directors and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

Communication with the Directors of Black Diamond Therapeutics

Any stockholder or interested party may communicate with our board of directors, as a whole, or with individual directors on the board of directors, through an established process for stockholder and other interested party communication. For a communication directed to the board of directors as a whole, stockholders and other interested parties may submit a written communication by postal mail to the attention of the chair of our board of directors at the following address: Black Diamond Therapeutics, Inc., Attention: Chair of the Board of Directors, c/o Corporate Secretary, One Main Street, 14th Floor Cambridge, MA 02142.

For a communication directed to an individual director in his capacity as a member of the board of directors, stockholders and other interested parties may send such communication to the attention of the individual director at the following address: Black Diamond Therapeutics, Inc., Attention: [Name of Individual Director], c/o Corporate Secretary, One Main Street, 14th Floor Cambridge, MA 02142.

We will forward by U.S. Mail any such communication to each director, and the chair of the board of directors in his capacity as a representative of the board of directors, to whom such communication is addressed to the address specified by each such director and the chair of the board of directors, unless there are safety or security concerns that mitigate against further transmission. A copy of any such written communication may also be forwarded to the Company’s general counsel and a copy of such communication may be retained for a reasonable period of time. You may submit your concern anonymously or confidentially.

Communications may be forwarded to other directors if they relate to important substantive matters and include suggestions or comments that may be important for other directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications.

The audit committee oversees the procedures for the receipt, retention, and treatment of complaints received by the Company regarding accounting, internal accounting controls, or audit matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. The Company has also established a toll-free telephone number for the reporting of such activity, which is (855)-996-3716.

Mr. Ingram resigned from our board in December 2022.

Non-Employee Director Compensation Program

Our non-employee directors are compensated pursuant to a formal policy, which we most recently amended and restated in March 2023, pursuant to which we pay our non-employee directors a cash retainer for service on the board of directors and for service on each committee on which the director is a member. The chairman of each committee receives a higher retainer for such service. The fees paid to non-employee directors for service on the board of directors and for service on each committee of the board of directors on which the director is a member are as follows:

	Annual Retainer for Board Membership
	Annual service on the board of directors					35,000
	Additional compensation for service as non-executive chair of the board of directors					30,000
	Additional Annual Retainer for Committee Membership*
	Annual service as member of the audit committee (other than chair)					7,500
	Annual service as chair of the audit committee					15,000
	Annual service as member of the compensation committee (other than chair)					5,000
	Annual service as chair of the compensation committee					10,000
	Annual service as member of the nominating and corporate governance committee (other than chair)					4,000
	Annual service as chair of the nominating and corporate governance committee					8,000

In April 2022, our compensation, nomination and corporate governance committee was split into two separate committees: a compensation committee and a nominating and corporate governance committee. Prior to such split, the annual retainer for such committee was $5,000 for members and $10,000 for the chair. The amounts reflected in the “Non-Employee Director Compensation Table” above reflect the pro-rated amount each applicable non-employee director received for serving on the compensation, nomination and corporate governance committee prior to April 2022, and the pro-rated amount each applicable non-employee director received for serving on the compensation committee and a nominating and corporate governance committee, as applicable.

Non-employee directors are given the opportunity to elect to receive all or a portion of their cash retainer and committee fees in the form of an equity award of unrestricted shares having a grant date fair value equal to the amount (or portion of the amount) of such retainer and committee fees. We also reimburse our non-employee directors for reasonable out-of-pocket expenses incurred by our non-employee directors in connection with attending our meetings of the board of directors and committees thereof.

In addition, each new non-employee director elected to our board of directors will be granted an option to purchase 33,000 shares of our common stock on the date of such director’s election or appointment to the board of directors, which will vest ratably in thirty-six (36) equal monthly installments following the grant date, subject to the director’s continued service on our board of directors through such vesting date. On the date of each annual meeting of stockholders of our Company, each continuing non-employee director will be granted an option to purchase 16,500 shares of our common stock, which will vest in full upon the earlier to occur of the first anniversary of the date of grant or the date of the next annual meeting, subject to the director’s continued service on our board of directors through such vesting date.

The value of all equity awards and all other cash compensation paid by the Company to any non-employee director in any calendar year may not exceed: (i) $1,000,000 in the first calendar year an individual

EXECUTIVE COMPENSATION

As an “emerging growth company,” we have opted to comply with the executive compensation disclosure rules applicable to “smaller reporting companies,” as such term is defined in the rules promulgated under the Securities Act. This section provides an overview of the compensation awarded to, earned by, or paid to each individual who served as our principal executive officer during our fiscal year 2022, and our next two most highly compensated executive officers in respect of their service to our Company for fiscal year 2022. We refer to these individuals as our named executive officers. Our named executive officers for fiscal year 2022 are:

•

David M. Epstein, Ph.D., our President and Chief Executive Officer;

•

Brent Hatzis-Schoch, our Chief Operating Officer and General Counsel; and

•

Fang Ni, Pharm. D., our Chief Business Officer and Chief Financial Officer.

Our executive compensation program is based on a pay for performance philosophy. Compensation for Drs. Epstein and Ni and Mr. Hatzis-Schoch is composed primarily of the following main components: base salary, bonus, and equity incentives in the form of performance-based restricted stock units and stock options. Like all full-time employees, our executive officers are eligible to participate in our health and welfare benefit plans. We will continue to evaluate our compensation philosophy and compensation plans and arrangements as circumstances require.

2022 Summary Compensation Table

The following table presents the compensation awarded to, earned by or paid to each of our named executive officers for the years indicated.

(1)

The amount reported represents the second installment of a one-time sign-on bonus totaling $50,000 paid to Dr. Ni in 2021 and 2020.

(2)

The Company granted performance restricted stock units (PRSUs) to Dr. Epstein, Mr. Hatzis-Schoch and Dr. Ni during fiscal year 2022 which will vest upon the achievement of certain R&D and corporate development milestones. The Company applied FASB ASC Topic 718, Compensation — Stock Compensation, to report the aggregate grant date fair value of the PRSUs based on the probability of achievement of the performance criteria as of the grant date. Under this guidance, the amounts reported reflect an accounting cost of zero for the PRSUs and do not correspond to the actual economic value that may be received by our executives if performance criteria are met and vesting occurs, and the maximum value of the PRSUs granted to Dr. Epstein, Mr. Hatzis-Schoch and Dr. Ni is $214,000, $64,200 and $70,620, respectively. There were no PRSUs granted during fiscal year 2021.

(3)

The amounts reported represent the aggregate grant date fair value of the stock options awarded to our named executive officers during fiscal years 2022 and 2021 calculated in accordance with FASB or ASC Topic 718, Compensation — Stock Compensation. Such grant date fair value does not take into account any estimated forfeitures. The assumptions used in calculating the grant date fair value of the stock option reported in this column are set forth in Note 8 to our audited consolidated financial

TABLE OF CONTENTS

statements in our Annual Report on Form 10-K for the year ended December 31, 2022. The amount reported in this column reflects the accounting cost for the stock option and does not correspond to the actual economic value that may be received by our executives upon the exercise of the stock option or any sale of the underlying shares of common stock.

(4)

The amounts reported reflect bonuses based upon achievement of certain company and individual performance metrics.

Narrative to 2022 Summary Compensation Table

Our board of directors and compensation committee review compensation annually for our executive officers. In setting executive base salaries and bonuses and granting equity incentive awards, we consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders, and a long-term commitment to our Company. We target a general competitive position, based on independent third-party benchmark analytics to inform the mix of compensation of base salary, bonus or long-term incentives.

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 executive compensation programs and related policies. In fiscal year 2022, the compensation committee (formerly our “compensation, nomination and corporate governance committee”) continued to retain Aon’s Human Capital Solutions practice, a division of Aon plc to provide it with market information, analysis and other advice relating to executive compensation on an ongoing basis. The compensation committee engaged Aon to, among other things, assist in developing a group of peer companies to help us determine overall compensation for our executive officers, as well as to assess each separate element of compensation. The goal was to ensure that the compensation we offer to our executive officers, individually as well as in the aggregate, is competitive and aligned with our business and executive talent requirements. We do not believe the retention of, and the work performed by, Aon creates any conflict of interest because Aon performs no other work for the Company besides advising the compensation committee.

Our compensation committee is responsible for determining the compensation for all executive officers. Our Chief Executive Officer makes recommendations to our compensation committee, 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. Based on its discretion, taking into account the factors noted above, the compensation, committee sets the compensation for each executive officer, including for the Chief Executive Officer, without the Chief Executive Officer present.

Base Salaries

Each named executive officer’s base salary is a fixed component of annual compensation for performing specific duties and functions, and has been established by our compensation committee or board of directors, as applicable, taking into account each individual’s role, responsibilities, skills, and experience. Base

TABLE OF CONTENTS

salaries for our named executive officers are reviewed annually by our compensation committee or board of directors, as applicable, typically in connection with our annual performance review process, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. For fiscal year 2022, the annual base salaries for Dr. Epstein, Mr. Hatzis-Schoch and Dr. Ni were $554,350, $452,100 and $411,740, respectively, representing an increase of 3%, 3% and 6%, respectively, over the annual base salaries of the prior year.

Annual Bonuses

Our named executive officers, as well as other executive officers, are eligible to participate in our Senior Executive Cash Incentive Bonus Plan, or the Bonus Plan, which is an annual bonus program intended to reward our named executive officers for meeting objective or subjective performance goals for a fiscal year. The Bonus Plan provides for cash payments based upon the attainment of performance targets established by the board of directors, which may relate to financial and operational measures or objectives with respect to the Company, as well as individual performance objectives. Annual corporate goals are established by the board of directors and reviewed and approved by the compensation committee at the beginning of each year. Each executive officer who is selected to participate in the Bonus Plan will have a target bonus opportunity set for each performance period.

With respect to performance in fiscal year 2022, the target bonus opportunity as a percentage of base salary for each of Dr. Epstein, Mr. Hatzis-Schoch and Dr. Ni was 50%, 40% and 40%, respectively. Other than for our Chief Executive Officer whose target award opportunity is solely based on corporate performance goals, the target award opportunity for each of our other named executive officers is based 20% on individual performance goals and 80% on corporate performance goals. Individual performance goals include objectives related to functions managed by the executive officer and other objectives supportive of corporate performance goals. We believe this executive bonus plan provides incentive that motivates and rewards achievement of performance goals that directly correlates to enhancement of stockholder value, consistent with our compensation philosophy.

In fiscal year 2022, we made substantial progress and achieved a number of significant milestones relating to our development programs BDTX-1535 and BDTX-4933 and our research activities as well as meeting key corporate goals related to organizational and financial objectives. In particular, in the areas of research and development we achieved key development objectives related to the initiation of the phase 1 study for BDTX-1535 and the enrollment of patients in the dose escalation portion of the study, the submission of the investigational new drug application for BDTX-4933, in addition to advancing two other pipeline programs towards development candidate nomination. We also delivered on critical organizational and financial objectives, such as the appointment of our new chief medical officer in June 2022, and ending 2022 with approximately $122.8 million in cash, cash equivalents and investments, which the Company believes is sufficient to fund its anticipated operating expenses and capital expenditure requirements into the third quarter of 2024. Based on a determination that the Company achieved corporate performance goals at 112% of target and taking into account individual performance for executive officers other than the chief executive officer, the compensation committee determined that the bonuses would be paid in the amounts as set forth above in the Summary Compensation Table, representing a payment at 112% of target for Dr. Epstein, 115% of target for Mr. Hatzis-Schoch and 120% of target for Mr. Ni.

Equity Compensation

Although we do not have a formal policy with respect to the grant of equity incentive awards to our executive officers, we believe that equity grants provide our executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives and our stockholders. In addition, we believe that equity grants with a time-based vesting feature promote executive retention because this feature incentivizes our executive officers to remain in our employment during the vesting period, while equity grants with performance-based vesting features encourage achievement of critical R&D and corporate development milestones. Accordingly, our board of directors periodically reviews the equity incentive compensation of our named executive officers and from time to time may grant equity incentive awards to them. During fiscal year 2022, we granted options to purchase shares of our common stock and restricted stock units with performance based vesting criteria to Dr. Epstein, Mr. Hatzis-Schoch, and Dr. Ni,

TABLE OF CONTENTS

with performance-based restricted stock units (PRSUs) representing 25% of the total equity awards to these individuals in 2022. Commencement of vesting of the performance restricted stock units granted to our named executive officers in 2022 is subject to the achievement within specified time periods in 2022 and 2023 of certain development objectives related to the phase 1 study of BDTX-1535, the investigational new drug application for BDTX-4933, and nomination of a development candidate for an undisclosed program, as well as certain financial and business development goals. Partial vesting of the PRSUs occurs upon achievement of the performance objectives, with full vesting of the PSRUs occurring 18 months from the grant date. See the “Outstanding Equity Awards at 2022 Fiscal Year End” table for additional detail.

Retirement Programs

401(k) Plan

We maintain a tax-qualified 401(k) and Profit Sharing defined contribution plan (the 401(k) Plan) in which substantially all of our full-time U.S. employees, including our executive officers, are eligible to participate. We provide an employer safe harbor matching contribution equal to 100% of a participant’s eligible contributions of up to 6% of eligible compensation, subject to limits established by the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the Code). All matching contributions are fully vested when made. Our 401(k) Plan is intended to provide our employees, including our executive officers, with an opportunity for tax-efficient retirement savings and long-term financial security. We do not sponsor any qualified or non-qualified defined benefit plans for any of our employees or executives.

Group Retirement Savings Plan

We maintained a Group Retirement Savings Plan (GRSP) into December 2022, which is a group retirement savings plan registered with the Canada Revenue Agency. Eligible employees of our Canadian subsidiary were able to contribute to the GRSP on their behalf or on behalf of their spouse, and income earned on these contributions is not taxable to associates until withdrawn from the GRSP. Employee contributions eligible for company match could not exceed the overall maximum amount allowed by the Income Tax Act (Canada), which amount is set by the Canada Revenue Agency each year.

Health and Welfare Benefits

All of our full-time employees, including our executive officers are eligible to participate in certain medical, disability and life insurance benefit programs offered by us. We pay the premiums for term life insurance and long-term disability for all of our employees, including our executive officers. We also provide all employees, including executive officers, with a flexible spending account plan, an employee stock purchase plan and paid time off benefits including, vacation, sick time and holidays.

Employee Stock Purchase Plan

Pursuant to our employee stock purchase plan, employees, including our named executive officers, have an opportunity to purchase our common shares at a discount on a tax-qualified basis through payroll deductions. The employee stock purchase plan is designed to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. The purpose of the employee stock purchase plan is to encourage our employees, including our named executive officers, to become our shareholders and better align their interests with those of our other shareholders.

Employment Arrangements with Our Named Executive Officers

In January 2020, we entered into employment agreements with Dr. Epstein and Mr. Hatzis-Schoch. Each of them is employed “at will.” The employment agreements provide for Dr. Epstein’s and Mr. Hatzis- Schoch’s continued employment and set forth their annual base salary of $515,000, and $420,000 (which have since been increased as set forth above), respectively, the terms of their discretionary annual bonus, the term of their employment, certain expense reimbursements, and their eligibility to participate in our benefit plans generally. Pursuant to the employment agreements, in the event that the named executive officer’s service relationship with the Company is terminated without “cause” (as defined in their employment agreements) or upon the named executive officer’s resignation from the Company for “good reason” (as defined in their employment agreements), in either case within 12 months after the occurrence of the first event constituting a “change in control” (as defined in their employment agreements), subject to the execution of an effective release of claims in favor of the Company, the named executive officer may be entitled to the following severance benefits: (i) a lump sum payment equal to twelve months (or in the case of Dr. Epstein, eighteen months) of his then current base salary or the base salary in effect immediately prior to the change in control, if higher; (ii) an amount equal to his annual target bonus for the then-current year (or in the case of Dr. Epstein, equal to eighteen months of his target bonus for the then-current year); (iii) immediate acceleration of all stock options and other stock-based awards held by the named executive officer; and (iv) up to twelve months (or in the case of Dr. Epstein, eighteen months) of COBRA premiums reimbursements. Upon the termination of a named executive officer’s service relationship by the Company without cause or upon the named executive officer’s resignation from the Company for good reason, in either case other than in connection with a change in control, subject to the execution of an effective release of claims in favor of the Company, the named executive officer may be entitled to the following severance benefits: (i) continuation of salary payments at the base salary rate effective at the time of termination for a period of twelve months following the termination date; (ii) an amount equal to his target bonus for the then-current year; (iii) up to twelve months of COBRA premiums reimbursements; and, in the case of Dr. Epstein only, (iv) partial accelerated vesting of Dr. Epstein’s outstanding stock options with respect to the same number of shares that would have vested if he had continued in employment with the Company through the next anniversary of the grant date for such option, in accordance with the vesting schedule applicable to such option, provided that if the termination date falls on an anniversary of the grant date of any stock option, no accelerated vesting will be provided for such option. Furthermore, for Dr. Epstein only, in the event of a termination of his employment by death or “disability” (as defined in Dr. Epstein’s employment agreement), and subject to Dr. Epstein’s (or his estate’s or heirs’, as applicable) execution of an effective release of claims in favor of the Company, Dr. Epstein is eligible to receive the following severance benefits: (i) continuation of salary payments at the base salary rate effective at the time of termination for a period of 75 days following the termination date; and (ii) partial accelerated vesting of Dr. Epstein’s outstanding stock options with respect to the same number of shares that would have vested if he had continued in employment with the Company through the next anniversary of the grant date for such option, in accordance with the vesting schedule applicable to such option, provided that if the termination date falls on an anniversary of the grant date of any stock option, no accelerated vesting will be provided for such option.

In addition, we entered into an employment agreement with Dr. Ni on August 3, 2020, which was amended effective March 9, 2023. Dr. Ni is employed “at will.” The employment agreement set forth Dr. Ni’s annual base salary of $450,860 and Dr. Ni is eligible for an annual performance-based incentive cash bonus in an amount up to 40% of Dr. Ni’s then-current base salary. In the event Dr. Ni’s employment is terminated for any reason, the Company shall pay or provide to Dr. Ni (i) any salary earned through the date of termination, (ii) unpaid expense reimbursements and (iii) any vested benefits Dr. Ni may have under any employee benefit plan of the Company through the date of termination (the “Accrued Obligations”).

TABLE OF CONTENTS

In the event Dr. Ni’s employment is terminated by the Company without Cause or by Dr. Ni for Good Reason outside of the Change in Control Period, in addition to the Accrued Obligations, subject to his signing and complying with a release agreement and the release agreement becoming irrevocable, Dr. Ni will be entitled to (i) receive a lump sum cash payment equal to 100% of Dr. Ni’s annual base salary then in effect, (ii) receive 100% of his target annual performance bonus for the then-current year and (iii) receive a monthly payment equal to the monthly employer contribution the Company would have made to provide health insurance had Dr. Ni remained employed, paid to either the group health plan provider, the COBRA provider or directly to Dr. Ni. In the event Dr. Ni’s employment is terminated by the Company without Cause or by Dr. Ni for Good Reason within the Change in Control Period, in addition to the Accrued Obligations, subject to his signing and complying with a release agreement and the release agreement becoming irrevocable, Dr. Ni will be entitled to the same rights listed immediately above and will also be entitled to full acceleration of vesting of any of his unvested equity awards. The terms “Cause,” “Good Reason” and “Change in Control Period” are each defined in Dr. Ni’s employment agreement.

In addition, each of our named executive officers have entered into an agreement with us, which contains protections of confidential information, requires the assignment of inventions and contains other restrictive covenants.

Compensation Risk Assessment

We believe that although a portion of the compensation provided to our named executive officers and other employees is performance-based, our executive compensation program does not encourage excessive or unnecessary risk taking. Our compensation programs are designed to encourage our named executive officers and other employees to remain focused on both short-term and long-term strategic goals, in particular in connection with our pay-for-performance compensation philosophy. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

Stock Option Grants to Executive Officers

We have granted stock options to our named executive officers as more fully described in the section entitled “Executive Compensation.”

Indemnification Agreements

We have entered into agreements to indemnify our directors and executive officers. These agreements, among other things, require us to indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts incurred by such person in any action or proceeding on account of any services undertaken by such person on behalf of our Company or any other company or enterprise to which such person provides services at our request to the maximum extent allowed under Delaware law.

Agreements with Our Stockholders

In connection with our preferred stock financings prior to our initial public offering, or IPO, we entered into investors’ rights, voting and right of first refusal and co-sale agreements as well as management rights letters containing registration rights, information rights, voting rights and rights of first refusal, among other things, with certain holders of our convertible preferred stock and certain holders of our common stock. The management rights letters provide for certain information rights and rights to consult with our management. These stockholder agreements and management rights letters terminated immediately prior to the completion of our IPO, other than the provisions relating to registration rights, which continued in effect following the completion of our IPO and entitle the holders of such rights to demand that we file a registration statement, subject to certain limitations, and to request that their shares be covered by a registration statement that we are otherwise filing.

TABLE OF CONTENTS

Related Person Transaction Policy

Our board of directors adopted a written related person transaction policy providing that transactions with our directors, executive officers and holders of five percent or more of our voting securities and their affiliates, each a related person, must be approved by the audit committee. This policy became effective on February 3, 2020 in connection with our IPO. Pursuant to this policy, the audit committee has the primary responsibility for reviewing and approving or disapproving “related person transactions,” which are transactions between us and related persons and in which a related person has or will have a direct or indirect material interest.

Pursuant to this policy, the material facts as to the related person’s relationship or interest in the transaction are disclosed to our audit committee prior to their consideration of such transaction. The audit committee will consider, among other factors that it deems appropriate, whether the transaction is on terms no less favorable to us than terms generally available in a transaction with an unaffiliated third-party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

DELINQUENT SECTION 16(A) REPORTS

Section 16(a) of the Exchange Act requires our officers and directors, and persons who own more than 10% of a registered class of our equity securities, to file reports of ownership and changes in ownership (Forms 3, 4, and 5) with the SEC. Officers, directors, and greater than 10% stockholders are required to furnish us with copies of all such forms which they file.

To our knowledge, based solely on our review of such reports, and any amendments thereto, or written representations from certain reporting persons, we believe that all of the filing requirements applicable to our officers, directors, greater than 10% beneficial owners, and other persons subject to Section 16 of the Exchange Act were complied with during the year ended December 31, 2022.

REPORT OF THE AUDIT COMMITTEE

The audit committee is appointed by the board of directors to assist the board of directors in fulfilling its oversight responsibilities with respect to (1) the integrity of Black Diamond Therapeutics’ financial statements, (2) Black Diamond Therapeutics’ compliance with legal and regulatory requirements, (3) the qualifications, independence and performance of Black Diamond Therapeutics’ independent auditors engaged for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for Black Diamond Therapeutics and (4) other matters as set forth in the charter of the audit committee approved by the board of directors.

Management is responsible for the preparation of Black Diamond Therapeutics’ financial statements and the financial reporting process, including its system of internal control over financial reporting and its disclosure controls and procedures. The independent registered public accounting firm is responsible for performing an audit of Black Diamond Therapeutics’ financial statements in accordance with the standards of the Public Company Accounting Oversight Board, or the PCAOB, and issuing a report thereon. The audit committee’s responsibility is to monitor and oversee these processes.

In connection with these responsibilities, the audit committee reviewed and discussed with management and the independent registered public accounting firm the audited consolidated financial statements of Black Diamond Therapeutics for the fiscal year ended December 31, 2022. The audit committee also discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the PCAOB and the SEC. In addition, the audit committee has received and reviewed the written disclosures and the letter from the independent registered public accounting firm as required by applicable requirements of the PCAOB regarding that firm’s communications with the audit committee concerning independence and has discussed with the independent registered public accounting firm their independence.

Based on the reviews and discussions referred to above, the audit committee recommended to the board of directors that the audited consolidated financial statements of Black Diamond Therapeutics be included in Black Diamond Therapeutics’ Annual Report on Form 10-K for the fiscal year ended December 31, 2022, that was filed with the SEC.

TABLE OF CONTENTS

HOUSEHOLDING

We have adopted a procedure called “householding,” which the SEC has approved. Under this procedure, we deliver a single copy of the Notice of Internet Availability and, if applicable, our proxy materials to multiple stockholders who share the same address, unless we have received contrary instructions from one or more of such stockholders. This procedure reduces our printing costs, mailing costs and fees. 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, our proxy materials to any stockholder at a shared address to which we delivered a single copy of any of these materials. This request may be submitted by contacting Black Diamond Therapeutics, Inc., One Main Street, 14th Floor, Cambridge, MA 02142, Attention: Corporate Secretary, telephone: 617-252-0848. Any such stockholder may also contact our Corporate Secretary using the above contact information if he or she would like to receive separate proxy statements, notice of internet availability and annual reports in the future. If you want to receive separate copies of the proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and phone number.

STOCKHOLDER PROPOSALS

A stockholder who would like to have a proposal considered for inclusion in our 2024 proxy statement must submit the proposal in accordance with the procedures outlined in Rule 14a-8 of the Exchange Act so that it is received by us no later than December 8, 2023. However, if the date of the annual meeting of stockholders in 2024 (the 2024 Annual Meeting) is changed by more than 30 days from the date of the previous year’s meeting, then the deadline is a reasonable time before we begin to print and send our proxy statement for the 2024 Annual Meeting. SEC rules set standards for eligibility and specify the types of stockholder proposals that may be excluded from a proxy statement. Stockholder proposals should be addressed to Black Diamond Therapeutics, Inc., One Main Street, 14th Floor, Cambridge, MA 02142, Attention: Corporate Secretary. We also encourage you to submit any such proposals via email to proxy@bdtx.com.

If a stockholder wishes to propose a nomination of persons for election to our board of directors or present a proposal outside of Rule 14a-8 of the Exchange Act at an annual meeting but does not wish to have the proposal considered for inclusion in our proxy statement and proxy card, our bylaws establish an advance notice procedure for such nominations and proposals. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting (i) by or at the direction of the board of directors or (ii) by a stockholder who was a stockholder of record at the time of giving notice, who is entitled to vote at the meeting, who is present (in person or by proxy) at the meeting and who has delivered timely notice in proper form to our Corporate Secretary of the stockholder’s intention to bring such business before the meeting.

In accordance with the advance notice procedure specified in our bylaws, for any stockholder proposal submitted outside the processes of Rule 14a-8 of the Exchange Act to be considered timely, the required notice must be in writing and received by our Corporate Secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting. However, in the event that the date of the annual meeting is convened more than 30 days before or more than 60 days after the first anniversary of the preceding year’s annual meeting, or if no annual meeting were held in the preceding year, a stockholder’s notice must be so received not later than the close of business on the later of (i) the 90th day prior to the scheduled date of such annual meeting or (ii) the 10th day following the day on which public announcement of the date of such annual meeting was first made. Accordingly, for stockholder proposals to be brought before the 2024 Annual Meeting, the required notice must be received by our corporate secretary at our principal executive offices not later than February 16, 2024 and no earlier than January 17, 2024. Stockholder proposals and the required notice should be addressed to Black Diamond Therapeutics, Inc., One Main Street, 14th Floor, Cambridge, MA 02142, Attention: Corporate Secretary.
