NOTICE OF 2024 ANNUAL MEETING OF STOCKHOLDERS

To be held online on June 6, 2024 at www.virtualshareholdermeeting.com/BDTX2024

Notice is hereby given that the 2024 Annual Meeting of Stockholders, or the Annual Meeting, of Black Diamond Therapeutics, Inc., will be held online on June 6, 2024 at 9:00 a.m. Eastern Time. The Annual Meeting will be held as a virtual meeting, which will be conducted via live webcast. We are utilizing a virtual-only meeting format in order to leverage technology to enhance stockholder access to the Annual Meeting by enabling attendance and participation from any location. We believe that the virtual-only meeting format will give stockholders the opportunity to participate fully and equally, and without cost, and to exercise the same rights as if they had attended an in-person meeting. You may attend the meeting online, vote your shares electronically and submit questions by visiting www.virtualshareholdermeeting.com/BDTX2024.

The purpose of the Annual Meeting is the following:

To elect two Class I director nominees to our board of directors, each to serve until the Company’s 2027 annual meeting of stockholders and until his or her successor has been duly elected and qualified, or until his 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, 2024;

To approve an amendment to our Fourth Amended and Restated Certification of Incorporation to limit the liability of certain officers of the Company as permitted by Delaware law; 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 April 9, 2024, 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. Our board of directors recommends a vote “FOR” the election of each of the two nominees for Class I directors, “FOR” the ratification of the appointment of our independent registered public accounting firm for the fiscal year ending December 31, 2024, and “FOR” the approval of the amendment to our approval of an amendment to our Fourth Amended and Restated Certificate of Incorporation to limit the liability of certain of our officers as permitted by Delaware law, as disclosed in more detail 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, 2023, or the 2023 Annual Report. We will mail the Notice of Availability on or about April , 2024, 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

TABLE OF CONTENTS

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 2023 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. There is no physical location for the Annual Meeting. You will not be able to attend the Annual Meeting in person.

Your vote is important. Whether or not you are able to attend the Annual Meeting virtually and vote your shares online, it is important that your shares be represented. To ensure that your vote is recorded promptly, please vote as soon as possible, even if you plan to attend the Annual Meeting, by submitting your proxy via the Internet at the address listed on the Notice of Availability, by telephone as described in the instructions included in the Notice of Availability or, if you requested copies of the proxy materials by mail, by completing, signing, dating and returning the proxy card. Submitting your vote via the Internet or by telephone or proxy card will not affect your right to vote online during the Annual Meeting if you decide to attend the Annual Meeting. If your shares are held in “street name” (i.e., held for your account by a broker or other nominee), you will receive instructions from your broker or other nominee explaining how to vote your shares, and you will have the option to cast your vote by telephone or over the Internet if your voting instruction form from your broker or nominee includes instructions and a toll-free telephone number or Internet website to do so. In any event, to be sure that your vote will be received in time, please cast your vote by your choice of available means, at your earliest convenience.

By order of the Board of Directors,

/s/ Mark A. Velleca

The mailing address of our principal executive offices is Black Diamond Therapeutics, Inc., One Main Street, 14th Floor, Cambridge, MA 02142.

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.

BLACK DIAMOND THERAPEUTICS, INC.
PROXY STATEMENT
FOR THE 2024 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 , 2024, we will begin mailing the Notice of Availability. Our proxy materials, including the Notice of the 2024 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 2023 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 , 2024. The Notice of Availability provides instructions as to how stockholders may access and review our proxy materials, including the Notice of the 2024 Annual Meeting of Stockholders, this proxy statement, the proxy card and our 2023 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 2024 Annual Meeting of Stockholders, this proxy statement and our 2023 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 April 9, 2024.

How many votes can be cast by all stockholders?

There were 52,530,334 shares of our common stock, par value $0.0001 per share, outstanding on April 9, 2024, 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 June 5, 2024.

•

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 June 5, 2024.

•

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 June 6, 2024.

•

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/BDTX2024. 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 our 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. We are utilizing a virtual-only meeting format in order to leverage technology to enhance stockholder access to the Annual Meeting by enabling attendance and participation from any location. We believe that the virtual-only meeting format will give stockholders the opportunity to participate fully and equally, and without cost, and to exercise the same rights as if they had attended an in-person meeting. We have designed our virtual format to enhance, rather than constrain, stockholder access, participation and communication.

Stockholders of record as of April 9, 2024 will be able to attend and participate in the Annual Meeting online by accessing www.virtualshareholdermeeting.com/BDTX2024.

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 Annual 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 June 6, 2024. Online access to the webcast will open approximately fifteen (15) minutes prior to the start of the

TABLE OF CONTENTS

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.

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 is available at www.proxyvote.com and during the Annual Meeting at www.virtualshareholdermeeting.com/BDTX2024.

Annual Meeting Technical Assistance

Beginning fifteen (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 your shares are held in “street name” through a broker, bank or other nominee, you must contact such broker, bank, or nominee holding your shares and follow their instructions to change your voting instructions.

How is a quorum reached?

Our Second Amended and Restated Bylaws, or bylaws, provide that a majority of the outstanding shares entitled to vote, present in person or by remote communication, if applicable, or represented by

TABLE OF CONTENTS

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 Annual 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.

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 our certificate of incorporation, or our bylaws. Except with respect to Proposal No. 3 (a proposal to amend our certificate of incorporation as permitted by Delaware law), 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. Proposal No. 3 is considered to be 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.”

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 two 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, 2024. Abstentions and broker non-votes, if any, will have no effect on the outcome of Proposal No. 2.

For Proposal No. 3, the approval of an amendment to our certificate of incorporation to limit the liability of certain of our officers as permitted by Delaware law requires the affirmative vote of the majority of our outstanding shares of capital stock entitled to vote. This means that more than 50% of our outstanding shares on the record date must vote “FOR” this proposal. Abstentions and broker non-votes, if any, will have the same effect on the outcome of Proposal No. 3 as a vote “AGAINST.”

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

TABLE OF CONTENTS

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 2025 must also satisfy the requirements of SEC Rule 14a-8 under the Exchange Act, and be received not later than , 2024. 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, then notice must be received within a reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC.

How can I know the voting results?

We plan to announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on Form 8-K, or Form 8-K, to be filed with the SEC within four business days following the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an amendment to the Form 8-K to publish the final results.

TABLE OF CONTENTS

PROPOSAL NO. 1 — ELECTION OF CLASS I DIRECTORS

Our board of directors currently consists of eight 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 Prakash Raman and Mark A. Velleca, and their terms will expire at Annual Meeting;

•

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, Shannon Campbell and Kapil Dhingra, and their terms will expire at the annual meeting of stockholders to be held in 2026.

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 Prakash Raman and Mark A. Velleca for election as the Class I 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.

Nominees for Election as Class I Directors

The following table identifies our director nominees, and sets forth their principal occupation and business experience during the last five years and their ages as of March 31, 2024.

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 two director nominees for Class I directors receiving the most votes 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 I directors nominated by our board of directors.

The board of directors recommends voting “FOR” the election of Prakash Raman and Mark A. Velleca, as the Class I directors, to serve for a three-year term ending at the annual meeting of stockholders to be held in 2027.

TABLE OF CONTENTS

PROPOSAL NO. 3 — APPROVAL OF AN AMENDMENT TO OUR CERTIFICATE OF INCORPORATION TO LIMIT THE LIABILITY OF CERTAIN OFFICERS OF THE COMPANY AS PERMITTED BY DELAWARE LAW

Background and Reasons for the Proposed Exculpation Amendment

In August 2022, the State of Delaware, which is our state of incorporation, enacted legislation that enables Delaware companies to limit the liability of certain of their officers in limited circumstances pursuant to amended Section 102(b)(7) of the General Corporation Law of the State of Delaware, or the DGCL. Amended DGCL Section 102(b)(7) permits exculpation for direct claims brought by stockholders for breach of an officer’s fiduciary duty of care, including class actions, but does not eliminate officers’ monetary liability for breach of fiduciary duty claims brought by the corporation itself or for derivative claims brought by stockholders in the name of the corporation. Furthermore, the limitation on liability does not apply to breaches of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, or any transaction in which the officer derived an improper personal benefit.

Our board of directors believes it is appropriate for public companies in states that allow exculpation of officers to have exculpation clauses in their certificates of incorporation. Adopting an officer exculpation provision that aligns with the protections afforded under the DGCL could prevent protracted or otherwise meritless litigation that distracts from our primary objective of creating stockholder value over the long term. The nature of the role of directors and officers often requires them to make decisions on crucial matters. Frequently, directors and officers must make decisions in response to time-sensitive opportunities and challenges, which can create substantial risk of investigations, claims, actions, suits, or proceedings seeking to impose liability on the basis of hindsight, especially in the current litigious environment and regardless of merit. Our board of directors believes that limiting concern about personal liability will empower officers to best exercise their business judgment in furtherance of stockholder interests without the distraction of potentially being subject to claims following actions taken in good faith.

In addition, our board of directors believes it is important to provide protection to officers to the extent permitted by the DGCL to attract and retain executive talent. This protection has long been afforded to directors and other public companies have updated their governing documents to align with amended Section 102(b)(7) of the DGCL, and we expect this practice to continue. The corporate law codes of several other states already permit corporations to exculpate officers in a similar manner to Section 102(b)(7). Therefore, our ability to attract and retain highly qualified officer candidates may be adversely impacted if we do not implement the expanded protections now offered under Delaware law. Further, our board of directors believes that the proposed amendment to our certificate of incorporation would not negatively impact shareholder rights, particularly taking into account the narrow class and type of claims for which officers’ liability would be exculpated.

Accordingly, on March 7, 2024, our board of directors determined that it is advisable and in the best interests of the Company and our stockholders to amend our certificate of incorporation to add Article X to adopt amended DGCL Section 102(b)(7), or the Exculpation Amendment, and extend exculpation protection to our officers, and authorized and approved the proposed Exculpation Amendment, subject to approval by our stockholders at the Annual Meeting. Our board of directors believes the proposed Exculpation Amendment would better position the Company to attract top officer candidates, retain our current officers and enable our officers to exercise their business judgment in furtherance of the interests of the stockholders without the potential for distraction posed by the risk of personal liability. Additionally, it would align the protections for our officers with those protections currently afforded to our directors.

Text of the Proposed Exculpation Amendment

Our certificate of incorporation currently provides for the exculpation of directors, but does not include a provision that allows for the exculpation of officers. The Exculpation Amendment would amend our certificate of incorporation by adding a new article to reflect new Delaware law provisions regarding exculpation of officers as follows:

TABLE OF CONTENTS

“ARTICLE X

OFFICER LIMITATION OF LIABILITY

1. Officers. To the fullest extent permitted by the DGCL, an Officer (as defined below) of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of his or her fiduciary duty as an Officer of the Corporation, except for liability (a) for any breach of the Officer’s duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) for any transaction from which the Officer derived an improper personal benefit, or (d) arising from any claim brought by or in the right of the Corporation. If the DGCL is amended after the effective date of this Certificate to authorize corporate action further eliminating or limiting the personal liability of Officers, then the liability of an Officer of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. For purposes of this Article X, “Officer” shall mean an individual who has been duly appointed as an officer of the Corporation and who, at the time of an act or omission as to which liability is asserted, is deemed to have consented to service of process to the registered agent of the Corporation as contemplated by 10 Del. C. § 3114(b).

2. Amendment or Modification. Any amendment, repeal or modification of this Article X by either of (i) the stockholders of the Corporation or (ii) an amendment to the DGCL, shall not adversely affect any right or protection existing at the time of such amendment, repeal or modification with respect to any acts or omissions occurring before such amendment, repeal or modification of a person serving as an Officer at the time of such amendment, repeal or modification.”

The proposed Certificate of Amendment to our certificate of incorporation, or the Certificate of Amendment, reflecting the foregoing Exculpation Amendment is attached as Appendix A to this proxy statement.

Timing and Effect of the Proposed Exculpation Amendment

If the proposed Exculpation Amendment is approved by our stockholders, it will become effective immediately upon the filing of the Certificate of Amendment with the Secretary of State of the State of Delaware, which we expect to file promptly after the Annual Meeting. Other than the addition of Article X, the remainder of our certificate of incorporation will remain unchanged after effectiveness of the Certificate of Amendment. If the proposed Exculpation Amendment is not approved by our stockholders, our certificate of incorporation will remain unchanged. In accordance with the DGCL, our board of directors may elect to abandon the proposed Exculpation Amendment without further action by the stockholders at any time prior to the effectiveness of the filing of the Certificate of Amendment with the Secretary of State of the State of Delaware, notwithstanding stockholder approval of the proposed Exculpation Amendment. The proposed Exculpation Amendment is not being proposed in response to any specific resignation, threat of resignation or refusal to serve by any officer.

Vote Required and Board of Directors’ Recommendation

The affirmative vote of holders of a majority of the shares outstanding and entitled to vote as of the record date is required to approve the Exculpation Amendment. Abstentions and broker non-votes will have the effect of a vote against the Exculpation Amendment.

The board of directors recommends voting “FOR” Proposal No. 3 to approve an amendment to our certificate of incorporation to limit the liability of certain officers of the Company as permitted by Delaware law.

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 of directors. 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 of directors.

•

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, or Nasdaq. 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

TABLE OF CONTENTS

company may not, 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 Mark A. Velleca, 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, 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. For more information on our director nomination process, please see “— Director Nomination Process.”

Board Committees

Our board of directors has established an audit committee, a compensation committee, and a nominating and corporate governance committee.

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, https://investors.blackdiamondtherapeutics.com/corporate-governance/governance-documents.

Audit Committee

Garry E. Menzel, Ali Behbahani and Prakash Raman serve on the audit committee, which is chaired by Garry E. Menzel. Our board of directors has determined that each member of the audit committee is “independent” for audit committee purposes as that term is defined by the rules of the SEC and Nasdaq, and that each has sufficient knowledge in financial and auditing matters to serve on the audit committee. Our board of directors has designated Garry E. Menzel as an “audit committee financial expert,” as defined under the applicable rules of the SEC. During the fiscal year ended December 31, 2023, the audit committee met five (5) times. The audit committee’s responsibilities include:

•

Compensation Committee

Ali Behbahani, Garry E. Menzel and Shannon Campbell serve on the compensation committee, which is chaired by Ali Behbahani. Our board of directors has determined that each member of the compensation committee is “independent” as defined in the applicable Nasdaq rules. During the fiscal year ended December 31, 2023, the compensation committee met three (3) times. The compensation committee’s responsibilities include:

•

annually reviewing and recommending to our 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 our board of directors the cash compensation of our Chief Executive Officer and (ii) reviewing and recommending to our board of directors any grants and awards to our Chief Executive Officer under equity-based plans;

TABLE OF CONTENTS

•

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., or Radford, has served as the compensation committee’s independent compensation consultant since 2019. Radford reports directly to the compensation committee, and the compensation committee has the sole authority to hire, fire and direct the work of Radford. Radford 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, Radford 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. Radford also provides the compensation committee with advice and analysis regarding compensation of non-employee directors. The compensation committee has assessed the independence of Radford pursuant to SEC and Nasdaq rules and concluded that the work of Radford for the compensation committee does not raise any conflict of interest.

Nominating and Corporate Governance Committee

Kapil Dhingra, Samarth Kulkarni and Prakash Raman serve on the nominating and corporate governance committee, which is chaired by Kapil Dhingra. 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. During the fiscal year ended December 31, 2023, the 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 our 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 our 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 our board of directors;

•

developing and recommending to our 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

TABLE OF CONTENTS

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. Our 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 our 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 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 eleven (11) times during fiscal year 2023. 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 our 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 our board of directors on which such person served (during the periods that such person served).

TABLE OF CONTENTS

Director Attendance at Annual Meeting of Stockholders

Under our corporate governance guidelines, each of our directors is expected to attend our annual meetings of stockholders to the extent practicable, and we encourage our directors to attend our annual meetings of stockholders. Last year, we held an annual meeting of stockholders on May 16, 2023, at which nine directors who were members of our board of directors at such time 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 short sales and derivative transactions of our stock and purchases or sales of puts, calls, or other derivative securities of the Company or any derivative securities that provide the economic equivalent of ownership of any of the Company’s securities or an opportunity, direct or indirect, to profit from any change in the value of the Company’s securities or engage in any other hedging transaction with respect to the Company’s securities, at any time, by our executive officers, directors, employees and certain designated consultants and contractors.

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.

Compensation Recovery Policy

In accordance with the requirements of the SEC and Nasdaq listing rules, our board of directors adopted a compensation recovery policy on October 2, 2023. The compensation recovery policy provides that in the event we are required to prepare a restatement of financial statements due to material noncompliance with any financial reporting requirement under securities laws, we will seek to recover any incentive-based compensation that was based upon the attainment of a financial reporting measure and that was received by any current or former executive officer during the three-year period preceding the date that the restatement was required if such compensation exceeds the amount that the executive officers would have received based on the restated financial statements.

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. To facilitate talent attraction and retention, we strive to make Black Diamond a safe and rewarding workplace, with opportunities for our employees to grow and develop in their careers, supported by strong compensation, benefits and health and wellness programs, and by programs that build connections between our employees.

Human Capital Management. As of February 15, 2024, we had 54 full-time employees. Our workforce is highly skilled, with 20 of our employees holding an M.D., Ph.D. or Pharm.D. degree. Of our full-time employees, 33 were engaged in research and development activities. None of our employees are represented by labor unions or covered by collective bargaining agreements. We consider our relationship with our employees to be good. Our future success depends on our ability to attract, develop and retain key personnel,

TABLE OF CONTENTS

maintain our culture, and ensure diversity and inclusivity 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 have adopted policies and initiatives that foster an inclusive work environment and diverse workforce. Our commitment to inclusivity is reflected in our corporate goals and underpins our social, cultural and philanthropic initiatives. We work collaboratively with external organizations to attract, retain and develop diverse talent by ensuring we have a culture of inclusivity for all.

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.

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

Our bylaws and corporate governance guidelines provide our board of directors the flexibility to determine the appropriate leadership structure for our board of directors, including whether the offices of

TABLE OF CONTENTS

Chief Executive Officer and chair should be separate or combined and why our board of directors’ leadership structure is appropriate given the specific characteristics or circumstances of our Company and our board of directors’ assessment of its leadership from time to time. Mark A. Velleca, our President and Chief Executive Officer since September 2023, also has served as the chair of our board of directors since December 2022, and Samarth Kulkarni currently serves as our lead independent director. Our board of directors has concluded that our current leadership structure is appropriate at this time. Our board of directors is of the view that the combined role of chair and Chief Executive Officer promotes united leadership and direction and provides management a clear focus to execute our strategy and business plans. As Chief Executive Officer, Dr. Velleca is best suited to ensure that critical business issues are brought before our board of directors, which enhances our board of directors’ ability to develop and implement business strategies. In sessions of our board of director meetings in which our management, including our Chief Executive Officer, does not participate, the lead independent director serves as a liaison to management on behalf of the non-employee members of our board of directors. The lead independent director’s duties and responsibilities also include serving as the liaison between the chair of our board of directors and the independent directors, reviewing meeting agendas and schedules of meetings of the board of directors to assure that there is sufficient time for discussion of all agenda items and having the authority to call meetings of the independent directors.

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 activities, operations, strategic direction, cybersecurity 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

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 2024, 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 chair 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	$	40,000
Additional Annual Retainer for Board Membership
Annual service as non-executive chair of the board	$	30,000
Annual service as lead independent director of the board	$	25,000
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

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 61,100 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 30,550 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 becomes a non-employee director; and (ii) $750,000 in any other calendar year. For the purpose of this limitation, the value of any equity award is its grant date fair value.

This program is intended to provide a total compensation package that enables us to attract and retain qualified and experienced individuals to serve as directors and to align our directors’ interests with those of our stockholders.

Employee directors will receive no additional compensation for their service as a director.

Narrative to 2023 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 2023, the compensation 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 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 2023, the annual base salaries for Dr. Velleca, Dr. Epstein, Dr. Ni

TABLE OF CONTENTS

and Dr. Yurasov were $620,000, $582,070, $450,860 and $488,250, respectively. For Dr. Yurasov, Dr. Epstein and Dr. Ni, this represented an increase of 5.00%, 5.00% and 9.50% , 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 2023, the target bonus opportunity as a percentage of base salary for each of Dr. Velleca, Dr. Epstein, Dr. Ni and Dr. Yurasov was 55%, 55%, 40% and 40%, respectively. Other than for our Chief Executive Officers 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 2023, we made substantial progress and achieved a number of significant milestones relating to our development programs BDTX-1535 and BDTX-4933. In particular, we achieved key development objectives related to the enrollment of patients in the phase 1 dose expansion portion of our BDTX-1535 study and the enrollment of patients in the phase 1 dose escalation portion of our BDTX-4933 study. We also delivered on critical financial objectives, such as completing an underwritten public offering in July 2023 for aggregate net proceeds totaling approximately $71.6 million, after deducting underwriting discounts and commissions, as well as other offering expenses and ending 2023 with approximately $131.4 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 second quarter of 2025. Based on a determination that the Company achieved corporate performance goals at 100% 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 100% of target for Dr. Velleca pro-rated for the period he served as CEO, 105% of target for Dr. Yurasov, and 105% of target for Dr. Ni. Dr. Epstein did not receive a bonus since he resigned as an employee prior to the payment date, though his separation agreement provided him with a cash amount equal to his target bonus.

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.

See the “Outstanding Equity Awards at 2023 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.

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

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.”

TABLE OF CONTENTS

Indemnification Agreements

Our certificate of incorporation provides that we will indemnify our directors and officers to the fullest extent permitted by Delaware law. In addition, we enter into indemnification agreements with our officers and directors that may be broader in scope than the specific indemnification provisions contained in the Delaware General Corporation Law. See “Limitation of Liability and Indemnification of Officers and Directors” below for additional information regarding these agreements.

Limitation of Liability and Indemnification of Officers and Directors

As permitted by Delaware law, provisions in our certificate of incorporation and bylaws limit or eliminate the personal liability of directors for a breach of their fiduciary duty of care as a director. The duty of care generally requires that, when acting on behalf of the corporation, a director exercises an informed business judgment based on all material information reasonably available to him or her. Consequently, a director will not be personally liable to us or our stockholders for monetary damages or breach of fiduciary duty as a director, except for liability for:

•

any breach of the director’s duty of loyalty to us or our stockholders;

•

any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

•

any act related to unlawful stock repurchases, redemptions or other distributions or payments of dividends; or

•

any transaction from which the director derived an improper personal benefit.

These limitations of liability do not limit or eliminate our rights or any stockholder’s rights to seek non-monetary relief, such as injunctive relief or rescission. These provisions will not alter a director’s liability under other laws, such as the federal securities laws or other state or federal laws. Our certificate of incorporation also authorizes us to indemnify our officers, directors and other agents to the fullest extent permitted under Delaware law.

As permitted by Delaware law, our bylaws provide that:

•

we will indemnify our directors, officers, employees and other agents to the fullest extent permitted by law;

•

we must advance expenses to our directors and officers, and may advance expenses to our employees and other agents, in connection with a legal proceeding to the fullest extent permitted by law; and

•

the rights provided in our bylaws are not exclusive.

If Delaware law is amended to authorize corporate action further eliminating or limiting the personal liability of a director or officer, then the liability of our directors or officers will be so eliminated or limited to the fullest extent permitted by Delaware law, as so amended. Our bylaws also permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in connection with their services to us, regardless of whether our bylaws permit such indemnification. We have obtained such insurance.

In addition to the indemnification provided for in our certificate of incorporation and bylaws, we enter into indemnification agreements with our directors and executive officers. These indemnification agreements require us, among other things, to indemnify our directors and executive officers for some expenses, including attorneys’ fees, expenses, judgments, fines and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of his or her service as one of our directors or executive officers or any other company or enterprise to which the person provides services at our request. We believe that these provisions and agreements are necessary to attract and retain qualified individuals to serve as directors and executive officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been

TABLE OF CONTENTS

advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable.

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.

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.

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, 2023. 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, 2023, that was filed with the SEC. The information contained in this report shall not be deemed to be (1) “soliciting material,” (2) “filed” with the SEC, (3) subject to Regulations 14A or 14C of the Exchange Act, or (4) subject to the liabilities of Section 18 of the Exchange Act. This report shall not be deemed incorporated by reference into any of our other filings under the Exchange Act or the Securities Act, except to the extent that we specifically incorporate it by reference into such filing.

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 2025 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 , 2024. However, if the date of the annual meeting of stockholders in 2025, or the 2025 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 2025 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, containing the information specified in our bylaws, 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 2025 Annual Meeting, the required notice must be received by our corporate secretary at our principal executive offices not later than March 10, 2025 and no earlier than February 6, 2025. 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.
