NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

(Amounts in thousands, except share and per share amounts)

1. NATURE OF BUSINESS AND BASIS OF PRESENTATION

Black Diamond Therapeutics, Inc. (the Company) is a clinical-stage oncology company developing MasterKey therapies that target families of oncogenic mutations in patients with cancer. The Company was originally organized as a limited liability company in December 2014 under the name ASET Therapeutics LLC. In September 2016, the Company was converted to a corporation under the laws of the State of Delaware under the name ASET Therapeutics, Inc. The Company changed its name to Black Diamond Therapeutics, Inc. in January 2018. Since its inception, the Company has devoted substantially all of its efforts to raising capital, obtaining financing and incurring research and development costs related to the development and advancement of its product candidates identified by its Mutation-Allostery-Pharmacology (MAP) drug discovery engine.

The Company is subject to risks and uncertainties common to clinical-stage companies in the biotechnology industry. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s technology will be obtained, that any products developed will obtain necessary government regulatory approval or that any products, if approved, will be commercially viable. The Company operates in an environment of rapid technological innovation and substantial competition from pharmaceutical and biotechnological companies. In addition, the Company is dependent upon the services of its employees, consultants and service providers. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.

On November 14, 2022, the Company filed a shelf registration statement on Form S-3 (the Shelf Registration Statement), with the Securities and Exchange Commission (the SEC), which covers the offering, issuance and sale of the Company’s common stock, preferred stock, debt securities, warrants and/or units of any combination thereof up to a maximum offering price of $500 million. The Company simultaneously entered into an Open Market Sale AgreementSM with Jefferies LLC (Jefferies), as sales agent, to provide for the issuance and sale by the Company of up to $150 million of its common stock from time to time through Jefferies (the ATM Program). The Shelf Registration Statement became effective on November 22, 2022. As of March 31, 2024, the Company sold 800,000 shares of its common stock pursuant to the ATM Program, resulting in gross proceeds to the Company of approximately $4.0 million ($3.9 million net of offering costs).

On July 5, 2023, the Company completed an underwritten public offering (the Follow-on Offering) of 15,000,000 shares of the Company’s common stock at a price to the public of $5.00 per share. The aggregate net proceeds from the Follow-on Offering totaled approximately $71.9 million, after deducting underwriting discounts and commissions.

The accompanying consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets, and the satisfaction of liabilities and commitments in the ordinary course of business. Historically, the Company has funded its operations primarily with proceeds from the sale of common stock and preferred stock. The Company has had recurring losses and negative cash flows from operations in all periods since inception and had an accumulated deficit of $435.7 million as of March 31, 2024. The Company expects to continue to generate operating losses for the foreseeable future.

As of May 9, 2024, the issuance date of the condensed consolidated financial statements, the Company expects that its cash, cash equivalents and investments will be sufficient to fund its currently planned operations for at least the next 12 months from the filing date of these condensed consolidated financial statements.

Table of Contents

The Company will seek additional funding through private or public equity financings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into collaborations or other arrangements. The terms of any financing may adversely affect the holdings or the rights of the Company's stockholders. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate some or all of its research and development programs, product portfolio expansion or commercialization efforts, or reduce headcount and general and administrative costs, which could adversely affect its business prospects. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed in the preparation of these condensed consolidated financial statements.

Principles of consolidation

The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and include the accounts of the Company and its wholly owned subsidiaries, Black Diamond Therapeutics Security Corporation and Black Diamond Therapeutics (Canada), Inc., after elimination of all significant intercompany accounts and transactions. On October 10, 2023, Black Diamond Therapeutics (Canada), Inc. was dissolved by way of voluntary dissolution.

Unaudited interim financial information

The condensed consolidated financial statements of the Company included herein have been prepared, without audit, pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this Quarterly Report, as is permitted by such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. In the opinion of the Company’s management, all adjustments (consisting of normal and recurring adjustments) considered necessary for a fair statement of the results for the interim periods presented have been included.

Use of estimates

The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual of research and development expenses and the valuation of stock-based awards. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ from those estimates or assumptions.

Table of Contents

The Company continues to monitor the impact of global economic developments, political unrest, high inflation, disruptions in capital markets, changes in international trade relationships and military conflicts, and health crises, on all aspects of its business, and has considered the impact of these factors on estimates within its financial statements. The extent to which future developments may impact the Company’s business, results of operations or financial condition are uncertain and cannot be predicted with confidence and there may be changes to estimates in future periods. As of the date of issuance of these condensed consolidated financial statements, the Company has not experienced material business disruptions or incurred impairment losses in the carrying value of its assets as a result of these factors and is not aware of any specific related event or circumstance that would require it to update its estimates.

Recently issued accounting pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09). ASU 2023-09 requires that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate). The standard is effective for annual and interim periods beginning after December 15, 2024. Adoption of the standard requires certain changes to be made prospectively, with some changes to be made retrospectively. The adoption is not expected to have a material impact on the Company’s consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures (Topic 280) (ASU 2023-07) which requires enhanced disclosure of (1) significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or loss, (2) the amount and description of the composition of other segment items which reconcile to segment profit or loss, and (3) the title and position of the entity’s CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and allocating resources. The amendments also expand the interim segment disclosure requirements. This new guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this ASU apply retrospectively to all prior periods presented in the financial statements. The Company is in the process of assessing the impact on its financial statements from the adoption of the new guidance and the period in which the new guidance will be adopted.

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (ASU 2023-06). The standard is effective for annual and interim periods beginning after December 15, 2024. Adoption of the standard requires certain changes to be made prospectively, with some changes to be made retrospectively. The adoption is not expected to have a material impact on the Company’s consolidated financial statements.

When developing fair value estimates, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. When available, the Company uses quoted market prices to measure fair value. The valuation technique used to measure fair value for the Company's Level 1 and Level 2 assets is a market approach, using prices and other relevant information generated by market transactions involving identical or comparable assets. If market prices are not available, the fair value measurement is based on models that use primarily market-based parameters including yield curves, volatilities, credit ratings and currency rates. In certain cases where market rate assumptions are not available, the Company is required to make judgments about assumptions market participants would use to estimate the fair value of a financial instrument.

There were no transfers in or out of Level 3 categories in the periods presented.

6. EQUITY METHOD INVESTMENT

In December 2022, the Company received 9,000,000 shares of common stock in a newly formed antibody-focused precision oncology company, Launchpad Therapeutics, Inc. (Launchpad), in exchange for contributing early discovery-stage antibody programs and granting Launchpad a license to use its MAP drug discovery engine to discover, develop and commercialize large molecule therapeutics. As of the transaction date and as of March 31, 2024, the Company has a 39.1% voting interest in Launchpad and one seat on Launchpad’s Board of Directors which provide the Company with significant influence over Launchpad. The remaining voting interest in Launchpad is held by Versant Ventures and New Enterprise Associates (NEA), who are shareholders of the Company.

The Company accounted for the transaction under the equity method and recorded the carrying value of the Company’s investment in Launchpad common shares of $2,250 in equity method investments in the consolidated balance sheets. The contributed in process research and development (IPR&D) had zero basis on the Company’s books prior to the transaction, therefore the Company recognized a gain on sale of IPR&D of $2,232 in the consolidated statements of operations and comprehensive loss for the year ended December 31, 2022. The Company also recognized a loss from investments in equity method investee of $1,540 in the consolidated statement of operations and comprehensive loss for the year ended December 31, 2022, associated with the Company’s proportionate share of Launchpad’s losses. The assets contributed by the Company were principally IPR&D and were not deemed a business by Launchpad, therefore the Company determined its remaining basis difference of $710 was substantially related to IPR&D and immediately expensed it. As of December 31, 2022, the carrying value of the investment in Launchpad was reduced to zero. Since the Company has no obligation to provide financing support to Launchpad, the Company is not required to record further losses exceeding the carrying value of the investment. The Company also determined that its investment in Launchpad is not material or significant to its operations or financial position. As of March 31, 2024, the carrying value of the investment in Launchpad was zero.

Options exercisable at March 31, 2024	4,242,313	$	11.65	6.7	$	3,488

For the three months ended March 31, 2024, total unrecognized compensation cost related to the unvested stock-options was $18,345, which is expected to be recognized over a weighted average period of 3.1 years.

Restricted stock units

The fair values of restricted stock units are based on the market value of the Company’s stock on the date of the grant. Under terms of the time-based restricted stock agreements covering the common stock, shares of restricted common stock are subject to a vesting schedule. The following table summarizes time-based restricted stock activity since January 1, 2024:


	Number of shares	Weighted average grant date fair value




Unvested restricted common stock as of December 31, 2023	20,799	$	2.41

Vested	(1,250)	$	3.79

Unvested restricted common stock as of March 31, 2024	19,549	$	2.32

The total fair value of time-based restricted stock units vested during the three months ended March 31, 2024 was $5.

For the three months ended March 31, 2024, total unrecognized compensation cost related to the time-based unvested restricted stock units was $6, which is expected to be recognized over a weighted average period of 0.1 years.

The Company had 19,000 performance restricted stock units outstanding at the year ended December 31, 2023. For the three months ended March 31, 2024, the Company granted no performance restricted stock units to its employees, released no performance restricted stock units due to the achievement of certain financing milestones, and had no performance restricted stock units forfeited. As of March 31, 2024, the Company had 19,000 performance restricted stock units outstanding.

Recognition of stock-based compensation expense associated with performance restricted stock units commences when the performance conditions are considered probable of achievement, using management’s best estimates, which consider the inherent risk and uncertainty regarding the future outcomes of the milestones.

Table of Contents

As of March 31, 2024, for performance-based restricted stock units that were outstanding, the achievement of the milestones that had not been met was considered not probable, and therefore no expense has been recognized related to these awards in the three months ended March 31, 2024.

Employee stock purchase plan

The 2020 ESPP enables eligible employees to purchase shares of the Company's common stock at the end of each six-month offering period at a price equal to 85% of the fair market value of the shares on the first business day or the last business day of the offering period, whichever is lower. Eligible employees generally included all employees. Offering periods begin on the first trading day of January and July of each year and end on the last trading day in June and December of each year, except for the first offering period which began on the first trading day in March and ended on the last trading day in June. Share purchases are funded through payroll deductions of up to 10% of an employee’s eligible compensation for each payroll period, up to $25 each calendar year.

During the three months ended March 31, 2024 and 2023, there were 26,659 and 33,202 shares, respectively, issued under the 2020 ESPP.

9. NET LOSS PER SHARE

Net loss per share

The following table summarizes the computation of basic and diluted net loss per share attributable to common shareholders of the Company (in thousands, except share and per share amounts):


	Three Months Ended March 31,
	2024		2023
Net loss	$	(18,225)	$	(20,875)
Weighted average common shares outstanding, basic and diluted	51,808,849		36,483,878
Net loss per share, basic and diluted	$	(0.35)	$	(0.57)

The Company’s potentially dilutive securities, which include options, unvested restricted stock and warrants to purchase common stock, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share for the periods indicated because including them would have had an anti-dilutive effect:


	Three Months Ended March 31,
	2024	2023
Options to purchase common stock	10,966,720	7,710,285
Unvested restricted stock	19,549	86,290
Shares issuable under employee stock purchase plan	86,858	102,351
Unvested performance restricted stock units	19,000	229,859
Warrants to purchase common stock	10,757	10,757
	11,102,884	8,139,542

10. LEASES

The Company has historically entered into lease arrangements for its facilities. As of March 31, 2024, the Company had two operating leases with required future minimum payments. The Company determined the classification of these leases to be operating leases and recorded right-of-use assets and lease liabilities as of the effective dates. The Company’s leases generally do not include termination or purchase options.

Operating leases

In July 2020, the Company entered into a seven-year agreement with an option to extend for five additional years to lease two floors totaling approximately 25,578 square feet of office space for its principal office, which is located in Cambridge, MA. The lease on the first floor commenced on August 1, 2020 and the lease on the second floor commenced March 9, 2021. The Company recognized the respective lease balances on the condensed consolidated balance sheets when the lease of each floor commenced. Under the terms of the lease, the Company was required to issue a $1,168 letter of credit as security for the lease, which was reduced to $779 in August 2023 pursuant to the terms of the lease agreement. Additionally, on December 12, 2022, the Company entered into a sublease for one floor of its Cambridge, Massachusetts office space. The sublease terminates on August 31, 2028, which is also the date on which the Company's lease terminates. Sublease income is recognized on a straight-line basis over the term of the sublease agreement. The Company was not relieved of its primary obligation under the Cambridge office lease as a result of the sublease.

In December 2020, the Company entered into an eleven-year agreement to lease approximately 18,120 square feet of office and laboratory space in New York, NY. The Company has an option to extend the lease for five additional years. The lease commenced August 26, 2021 and the related lease balance was recognized on the condensed consolidated balance sheet.

The following table contains a summary of the lease costs recognized under ASC 842 and other information pertaining to the Company’s operating lease for the three months ended March 31, 2024 and 2023:


	Three Months Ended March 31,
	2024		2023
Lease Cost
Operating lease cost	$	1,054	$	1,054
Short-term lease cost	17		17
Variable lease cost	237		256
Sublease income	(456)		(135)
Total lease cost	$	852	$	1,192


Other Operating Lease Information	March 31, 2024			March 31, 2023

Cash paid for amounts included in the measurement of lease liability	$	1,080		$	1,051
Weighted-average remaining lease term	6.7			7.6
Weighted-average discount rate	5.3		%	5.3		%

The variable lease costs for the three months ended March 31, 2024 and 2023 include common area maintenance and other operating charges. As the Company’s leases do not provide an implicit rate, the Company utilized its incremental borrowing rate to discount lease payments, which reflects the fixed rate at which the Company could borrow on a collateralized basis the amount of the lease payments in the same currency, for a similar term, in a similar economic environment.

Table of Contents

Future minimum lease payments under the Company’s operating leases as of March 31, 2024 were as follows:


	As of March 31, 2024
2024 (excluding the three months ended March 31, 2024)	$	3,279
2025	4,477
2026	4,599
2027	4,724
2028	3,926
Thereafter	8,324
Total lease payments	29,329
Less: interest	(4,784)
Total lease liability	$	24,545

11. COMMITMENTS AND CONTINGENCIES

The Company enters into contracts in the normal course of business with contract research organizations (CROs), contract manufacturing organizations (CMOs) and other third parties for preclinical research studies, clinical trials and testing and manufacturing services. These contracts do not contain minimum purchase commitments and are cancelable upon prior written notice. Payments due upon cancellation consist only of payments for services provided or expenses incurred, including noncancelable obligations of service providers, up to the date of cancellation.

License agreements

The Company is a party to license agreements, which include contingent payments. These payments will become payable if and when certain development, regulatory and commercial milestones are achieved. As of March 31, 2024, the satisfaction and timing of the contingent payments is uncertain and not reasonably estimable.

Indemnification agreements

In the ordinary course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with members of its board of directors and executive officers that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is, in many cases, unlimited. To date, the Company has not incurred any material costs as a result of such indemnifications. The Company is not aware of any indemnification arrangements that could have a material effect on its financial position, results of operations or cash flows, and it has not accrued any liabilities related to such obligations in its consolidated financial statements as of March 31, 2024 or December 31, 2023.

Legal proceedings

The Company is not currently party to and is not aware of any material legal proceedings. At each reporting date, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company expenses as incurred the costs related to such legal proceedings.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the unaudited condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report and our audited consolidated financial statements and related notes thereto for the year ended December 31, 2023, as well as Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in our Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the SEC on March 12, 2024. This discussion and analysis and other parts of this Quarterly Report contain forward-looking statements based upon current beliefs, plans and expectations that involve risks, uncertainties and assumptions, such as statements regarding our plans, objectives, expectations, intentions and projections. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth in our Annual Report on Form 10-K and in other SEC filings.

Overview

We are a clinical-stage oncology company developing MasterKey therapies that target families of oncogenic mutations in patients with cancer. The foundation of our company is built upon a deep understanding of cancer genetics, onco-protein structure and function, and medicinal chemistry. Our MasterKey therapies are designed to address a broad spectrum of genetically defined tumors, overcome resistance, minimize wild-type mediated toxicities, and be brain-penetrant to treat central nervous system (CNS) disease. Our compounds target families of oncogenic mutations in clinically validated pathways. We are advancing two clinical-stage programs: BDTX-1535, a brain-penetrant, fourth-generation epidermal growth factor receptor (EGFR) MasterKey inhibitor, targeting epidermal growth factor receptor mutant (EGFRm) non-small cell lung cancer (NSCLC) and glioblastoma (GBM), and BDTX-4933, a brain-penetrant, RAF MasterKey inhibitor targeting KRAS, NRAS and BRAF alterations in solid tumors.

We believe that our lead product candidate, BDTX-1535, has the potential to treat newly diagnosed patients with EGFRm NSCLC, as well as those with recurrent disease, based upon BDTX-1535’s ability to address greater than 50 classical and non-classical oncogenic driver mutations with greater potency than other EGFR tyrosine kinase inhibitors (TKIs), as well as uniquely target the C797S resistance mutation which can be acquired after treatment with osimertinib. In our Phase 1 trial in patients with recurrent EGFRm NSCLC, BDTX-1535 was shown to be well tolerated and achieve durable clinical responses in patients whose tumors expressed a range of mutation subtypes, including the acquired C797S resistance mutation and a spectrum of non-classical mutations.

In April 2024, at the American Association of Cancer Research (AACR) annual meeting, we described real world evidence of the evolving EGFR mutation landscape in patients with NSCLC and the potential of BDTX-1535 to address a broader range of mutations compared to existing therapies. The analyses revealed a broad spectrum of non-classical mutations, as well as an increased prevalence of the acquired resistance mutation, C797S. These non-classical EGFR mutations were present in 22-30% of newly diagnosed EGFRm NSCLC patients.

We are currently evaluating BDTX-1535 in a Phase 2 clinical trial in patients with EGFRm NSCLC in the second- and third-line settings with non-classical driver mutations and acquired C797S resistance mutation, and in the first-line setting in patients with EGFRm NSCLC harboring non-classical EGFR mutations. We expect to announce results from the second- and third-line cohorts in the third quarter of 2024 and results from the first-line cohort in the first quarter of 2025. We are also assessing the potential development of BDTX-1535 for patients with EGFRm NSCLC following adjuvant treatment with osimertinib, where the broad mutation coverage of BDTX-1535 of C797S and non-classical mutations may be of benefit.

Table of Contents

We released top-line GBM results from the BDTX-1535 Phase 1 dose escalation study in the fourth quarter of 2023, showing clinical activity in heavily pretreated patients with GBM. BDTX-1535 was shown to be generally well tolerated and no new safety signals were observed. In the fourth quarter of 2023, enrollment began in a “window of opportunity” (also known as a Phase 0/1 “Trigger”) trial sponsored by the Ivy Brain Tumor Center, in patients with recurrent high-grade glioma (HGG). We plan to present Phase 1 dose escalation data and “window of opportunity” results at the American Society of Clinical Oncology (ASCO) Annual Meeting on June 1, 2024, which will inform potential next steps in the development of BDTX-1535 in GBM.

Our second product candidate, BDTX-4933, is designed to be a potent and selective, reversible oral inhibitor that targets broad families of oncogenic BRAF, KRAS and NRAS alterations. BDTX-4933 selectively targets constitutively active RAF dimers resulting from either BRAF mutations or other upstream oncogenic MAPK pathway alterations, such as KRAS and NRAS alterations. In preclinical tumor models, we observed that BDTX-4933 demonstrated brain-penetrant activity and achieved regression of tumors carrying a broad spectrum of KRAS mutations, NRAS alterations, as well as BRAF Class I, II, and III mutations. We initiated a Phase 1 clinical trial for BDTX-4933 in the second quarter of 2023 in patients with BRAF and select KRAS and NRAS mutation-positive cancers, with an emphasis on patients with non-G12C KRAS mutant NSCLC. The trial is currently in dose escalation with an update anticipated in the fourth quarter of 2024.

Since our inception in 2014, we have devoted substantially all of our efforts and financial resources to organizing and staffing our company, business planning, raising capital, discovering product candidates and securing related intellectual property rights while conducting research and development activities for our programs. We do not have any products approved for sale and have not generated any revenue from product sales. We may never be able to develop or commercialize a marketable product. We have not yet successfully completed any pivotal clinical trials, obtained any regulatory approvals, manufactured a commercial-scale drug, or conducted sales and marketing activities.

To date, we have funded our operations with proceeds from the sale of common stock and preferred stock. Since inception, we have incurred significant operating losses. Our net losses were $18.2 million and $20.9 million for the three months ended March 31, 2024 and 2023, respectively. As of March 31, 2024, we had an accumulated deficit of $435.7 million. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of one or more of our current or future product candidates. We expect that our expenses and capital requirements will increase substantially in connection with our ongoing activities, particularly if and as we:

•advance clinical trials for BDTX-1535 and BDTX-4933;

•obtain, maintain, expand, enforce and protect our intellectual property portfolio;

•attract and retain key clinical, scientific, management and commercial personnel;

•seek marketing approvals for our product candidates that successfully complete clinical trials, if any; and

•acquire or in-license additional product candidates.

As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, which may include collaborations with other companies or other strategic transactions. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we fail to raise capital or enter into such agreements as and when needed, we may have to significantly delay, scale back or discontinue the development and commercialization of one or more of our product candidates, and reduce headcount and general and administrative costs.

Table of Contents

Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.

Additionally, we continue to actively monitor macroeconomic conditions and market volatility resulting from global economic developments, political unrest, high inflation, disruptions in capital markets, changes in international trade relationships and military conflicts, and health crises. While we believe such factors have had no significant impact on our business or financial results during the periods presented, future developments and potential impacts on our business are uncertain and cannot be predicted with confidence.

As of March 31, 2024, we had cash, cash equivalents and investments of approximately $115.2 million, which we believe will enable us to fund our operating expenses and capital expenditure requirements into the third quarter of 2025. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. See “—Liquidity and capital resources.” To finance our operations beyond that point, we will need to raise additional capital, which cannot be assured. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of our product candidates or other research and development initiatives.

Components of our results of operations

Revenue

To date, we have not generated any revenue from any sources, including from product sales, and we do not expect to generate any revenue from the sale of products in the foreseeable future. If our development efforts for our product candidates are successful and result in regulatory approval, or license agreements with third parties, we may generate revenue in the future from product sales. However, there can be no assurance as to when we will generate such revenue, if at all.

Operating expenses

Research and development expenses

Research and development expenses consist primarily of costs incurred for our research activities, including our drug discovery efforts and the development of our product candidates. We expense research and development costs as incurred, which include:

•expenses incurred to conduct the necessary preclinical studies and clinical trials required to obtain regulatory approval;

•expenses incurred under agreements with contract research organizations (CROs) that are primarily engaged in the oversight and conduct of our drug discovery efforts, preclinical studies, and clinical trials as well as under agreements with contract manufacturing organizations (CMOs) that are primarily engaged to provide preclinical and clinical drug substance and product for our research and development programs;

•other costs related to the conduct of preclinical studies, clinical trials, and our drug discovery efforts, including acquiring and manufacturing materials, manufacturing validation batches, fees to investigative sites and consultants that conduct our clinical trials, preclinical studies and other scientific development support services;

•payments made in cash or equity securities under third-party licensing, acquisition and option agreements;

•employee-related expenses, including salaries and benefits, travel and stock-based compensation expense for employees engaged in research and development functions;

•costs related to compliance with regulatory requirements; and

Table of Contents

•allocated facilities-related costs, depreciation and other expenses, which include rent and utilities.

We recognize external development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our service providers. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual costs. Any nonrefundable advance payments that we make for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. Such amounts are expensed as the related goods are delivered or the related services are performed, or until it is no longer expected that the goods will be delivered or the services rendered.

Our direct external research and development expenses consist primarily of external costs, such as fees paid to outside consultants, CROs, CMOs and research laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities. Our direct research and development expenses also include fees incurred under license, acquisition and option agreements. We do not allocate employee costs, costs associated with our discovery efforts, laboratory supplies, and facilities, including depreciation or other indirect costs, to specific programs because these costs are deployed across multiple programs and, as such, are not separately classified. We use internal resources primarily to conduct our research and discovery as well as for managing our preclinical development, process development, manufacturing and clinical development activities. These employees work across multiple programs and, therefore, we do not track their costs by program.

Development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. As a result, we expect that our research and development expenses will increase substantially over the next several years as we continue our clinical trials for BDTX-1535 and BDTX-4933. In addition, we may incur additional expenses related to milestone and royalty payments payable to third parties with whom we may enter into license, acquisition and option agreements to acquire the rights to future product candidates.

At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the clinical development of any of our product candidates or when, if ever, material net cash inflows may commence from any of our product candidates. The successful development and commercialization of our product candidates is highly uncertain. This uncertainty is due to the numerous risks and uncertainties associated with product development and commercialization, including the uncertainty of the following:

•the scope, progress, outcome and costs of our clinical trials and other development activities;

•successful patient enrollment in and the initiation and completion of clinical trials;

•the timing, receipt and terms of any marketing approvals from applicable regulatory authorities including the U.S. Food and Drug Administration (FDA) and non-U.S. regulators;

•the extent of any required post-marketing approval commitments to applicable regulatory authorities;

•establishing clinical and commercial manufacturing capabilities or making arrangements with third-party manufacturers in order to ensure that we or our third-party manufacturers are able to make product successfully;

•development and timely delivery of clinical-grade and commercial-grade drug formulations that can be used in our clinical trials and for commercial launch;

•obtaining, maintaining, defending and enforcing patent claims and other intellectual property rights;

•significant and changing government regulation;

•launching commercial sales of our product candidates, if and when approved, whether alone or in collaboration with others; and

Table of Contents

•maintaining a continued acceptable safety profile of our product candidates following approval, if any, of our product candidates.

Any changes in the outcome of any of these variables with respect to the development of our product candidates could mean a significant change in the costs and timing associated with the development of these product candidates. For example, if the FDA or another regulatory authority were to delay our planned start of clinical trials or require us to conduct clinical trials or other testing beyond those that we currently expect or if we experience significant delays in enrollment in any of our planned clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development of that product candidate.

General and administrative expenses

General and administrative expenses consist primarily of salaries and benefits, travel and stock-based compensation expense for personnel in executive, business development, finance, human resources, legal, information technology, pre-commercial and support personnel functions. General and administrative expenses also include direct and allocated facility-related costs as well as insurance costs and professional fees for legal, patent, consulting, investor and public relations, accounting and audit services.

We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support continued development of our product candidates and prepare for potential commercialization activities. Additionally, if and when we believe a regulatory approval of a product candidate appears likely, we anticipate an increase in payroll and other employee-related expenses as a result of our preparation for commercial operations, especially as it relates to the sales and marketing of that product candidate.

Other income (expense)

Other income (expense) consists primarily of interest income earned on our cash equivalents and investment balances, sublease income, realized and unrealized foreign currency transaction gains and losses, and gain (loss) on sale of IP related to equity method investment.

Equity in (losses) of unconsolidated entity

Equity in (losses) of unconsolidated entity consists of our share of equity method investee losses on the basis of our equity ownership percentage and IPR&D charges resulting from basis differences.

Results of operations

Comparison of the three months ended March 31, 2024 and 2023

The following table summarizes our results of operations for the three months ended March 31, 2024 and 2023:

Research and development

Research and development expenses were $13.5 million for the three months ended March 31, 2024, compared to $14.8 million for the three months ended March 31, 2023. The following table summarizes our research and development expenses for the three months ended March 31, 2024 and 2023:


	Three Months Ended March 31,
	2024		2023		Change
	(in thousands)
BDTX-1535 research and development expenses	$	5,742	$	3,733	$	2,009
BDTX-4933 research and development expenses	1,507		1,679		(172)

Other research programs and platform development expenses	602		2,787		(2,185)
Personnel expenses	4,528		5,109		(581)

Other expenses	306		436		(130)
	$	13,545	$	14,753	$	(1,208)

The decrease of $1.2 million for the three months ended March 31, 2024 was primarily due to an increase of $2.0 million related to the progression of our clinical trial for BDTX-1535, offset by decreased spend relating to other research programs and platform development of $2.2 million due to reduced spending on early discovery projects as we deepen our focus on our clinical-stage assets, compared to the three months ended March 31, 2023. In addition, personnel expenses decreased by $0.6 million as we continue to capitalize on workforce efficiencies and focus on our development programs.

Table of Contents

General and administrative

General and administrative expenses were $6.7 million for the three months ended March 31, 2024 compared to $6.8 million for the three months ended March 31, 2023. This was primarily a result of a decrease in personnel-related costs, legal and other professional fees.

Other income (expense)

Other income was $2.0 million for the three months ended March 31, 2024, compared to $0.7 million for the three months ended March 31, 2023. The increase was primarily attributable to accretion on investments increasing at a higher rate in 2024 compared to 2023.

Liquidity and capital resources

Sources of liquidity

Since our inception, we have not generated any revenue from any product sales or any other sources and have incurred significant operating losses and negative cash flows from our operations. We have not yet commercialized any of our product candidates, and we do not expect to generate revenue from sales of any product candidates for several years, if at all. We have funded our operations to date primarily with proceeds from the sale of common and preferred stock.

On February 3, 2020, we completed an IPO of 12,174,263 shares of our common stock, including the exercise in full by the underwriters of their option to purchase up to 1,587,947 additional shares of common stock, for aggregate gross proceeds of $231.3 million. We received $212.1 million in net proceeds after deducting underwriting discounts and commissions and other estimated offering expenses payable by us. Through March 31, 2024, we had received net cash proceeds of $200.6 million from previous sales of our preferred stock and as of March 31, 2024, we had cash, cash equivalents and investments of $115.2 million.

On November 14, 2022, we filed a shelf registration statement on Form S-3 (the Shelf Registration Statement) with the SEC, which covers the offering, issuance and sale of our common stock, preferred stock, debt securities, warrants and/or units of any combination thereof up to a maximum price of $500 million. We simultaneously entered into an Open Market Sale AgreementSM (the Sales Agreement) with Jefferies LLC (Jefferies), as sales agent, to provide for the issuance and sale by us of up to $150 million of our common stock, or the Shares, from time to time through Jefferies as our sales agent (the ATM Program). The Shelf Registration Statement became effective on November 22, 2022. Upon delivery of a placement notice and subject to the terms and conditions of the Sales Agreement, Jefferies may sell the Shares by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act. We may sell the Shares in amounts and at times to be determined by us from time to time subject to the terms and conditions of the Sales Agreement, but we have no obligation to sell any Shares under the Sales Agreement. We or Jefferies may suspend or terminate the offering of Shares upon notice to the other party and subject to other conditions. As of March 31, 2024, we sold 800,000 shares of our common stock pursuant to the ATM Program, resulting in gross proceeds to us of approximately $4.0 million ($3.9 million net of offering costs).

On July 5, 2023, we completed an underwritten public offering (the Follow-on Offering) of 15,000,000 shares of our common stock at a price to the public of $5.00 per share. The aggregate net proceeds from the Follow-on Offering totaled approximately $71.6 million after deducting underwriting discounts and commissions, as well as other offering expenses. The underwriters did not exercise any portion of their 30-day overallotment option to purchase up to an additional 2,250,000 shares of our common stock at the public offering price, which expired on July 29, 2023, and therefore no additional proceeds from the Follow-on Offering were received.

Cash flows

The following table summarizes our sources and uses of cash for each of the periods presented (in thousands):


	Three Months Ended March 31,
	2024		2023
Cash used in operating activities	$	(21,199)	$	(20,031)
Cash (used in) provided by investing activities	(13,734)		24,806
Cash provided by financing activities	4,130		51
Net increase (decrease) in cash and cash equivalents	$	(30,803)	$	4,826

Operating activities

During the three months ended March 31, 2024, we used cash in operating activities of $21.2 million, primarily resulting from our net loss of $18.2 million, partially offset by the non-cash charge related to stock compensation expense of $1.7 million.

During the three months ended March 31, 2023, we used cash in operating activities of $20.0 million, primarily resulting from our net loss of $20.9 million, partially offset by the non-cash charge related to stock compensation expense of $2.7 million.

Changes in accounts payable and accrued expenses in all periods were generally due to growth in our business, the advancement of our product candidates and the timing of vendor invoicing and payments.

Investing activities

During the three months ended March 31, 2024, we had cash used in investing activities of $13.7 million primarily from the sales and maturities of investments, netted against our purchase of investments.

During the three months ended March 31, 2023, we had cash provided by investing activities of $24.8 million primarily from the sales and maturities of investments.

Financing activities

During the three months ended March 31, 2024, we had cash provided by financing activities of $4.1 million, consisting of proceeds from exercise of stock options and participation in the employee stock purchase plan as well as the sale of shares of our common stock in March 2024 pursuant to the ATM Program.

During the three months ended March 31, 2023, we had cash provided by financing activities of $0.1 million consisting of proceeds from the participation in the employee stock purchase plan.

Funding requirements

We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we advance clinical trials of our product candidates. In addition, we expect to incur additional costs associated with operating as a public company, including significant legal, accounting, investor relations and other expenses. The timing and amount of our operating expenditures will depend largely on our ability to:

•advance BDTX-1535 and BDTX-4933 through clinical trials;

•manufacture, or have manufactured on our behalf, our drug material and develop processes for late stage and commercial manufacturing;

•seek regulatory approvals for any product candidates that successfully complete clinical trials;

Table of Contents

•establish a sales, marketing, medical affairs and distribution infrastructure to commercialize any product candidates for which we may obtain marketing approval and intend to commercialize on our own;

•hire additional clinical, quality control and scientific personnel; and

•obtain, maintain, expand, enforce and protect our intellectual property portfolio.

As of March 31, 2024, we had cash, cash equivalents and investments of $115.2 million. We believe that our existing cash, cash equivalents and investments will enable us to fund our operating expenses and capital expenditure requirements into the third quarter of 2025. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect. We anticipate that we will require additional capital as we seek regulatory approval of our product candidates and if we choose to pursue in-licenses or acquisitions of other product candidates. If we receive regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution, depending on where we choose to commercialize.

Because of the numerous risks and uncertainties associated with research, development and commercialization of product candidates, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to further reduce or terminate our operations. Our future funding requirements will depend on and could increase significantly as a result of many factors, including:

•the scope, progress, results and costs of developing our product candidates, and conducting clinical trials;

•the costs, timing and outcome of regulatory review of our product candidates;

•the costs, timing and ability to manufacture our product candidates to supply our clinical development efforts and our clinical trials;

•the costs of future activities, including product sales, medical affairs, marketing, manufacturing and distribution, for any of our product candidates for which we receive marketing approval;

•subject to receipt of regulatory approval, the costs of commercialization activities for our product candidates, to the extent such costs are not the responsibility of any future collaborators, including the costs and timing of establishing product sales, marketing, distribution and manufacturing capabilities;

•the ability to receive additional non-dilutive funding;

•the revenue, if any, received from commercial sale of our product candidates, should any of our product candidates receive marketing approval;

•the costs of preparing, filing and prosecuting patent applications, obtaining, maintaining, expanding and enforcing our intellectual property rights and defending intellectual property-related claims;

•our ability to establish and maintain collaborations on favorable terms, if at all;

•the extent to which we acquire or in-license other product candidates and technologies; and

•the costs of operating as a public company.

Table of Contents

As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time, if ever, as we can generate substantial product revenue from product sales, we expect to finance our operations through a combination of public or private equity offerings, debt financings, collaborations, strategic partnerships and alliances or marketing, distribution or licensing arrangements with third parties or through other sources of financing. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. However, the trading prices for our common stock and for other biopharmaceutical companies have been highly volatile. As a result, we may face difficulties raising capital through sales of our common stock, and such sales may be on unfavorable terms. Similarly, adverse macroeconomic conditions and market volatility resulting from global economic developments, political unrest, high inflation, global health crises, or other factors could materially and adversely affect our ability to consummate an equity or debt financing on favorable terms or at all. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all.

To the extent that we raise additional capital through the sale of private or public equity or convertible debt securities, the ownership interest of our stockholders may be materially diluted, and the terms of such securities could include liquidation or other preferences and anti-dilution protections that could adversely affect the rights of our common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, that could adversely impact our ability to conduct our business. In addition, debt financing may involve significant cash payment obligations and specific financial ratios that may restrict our ability to operate our business would result in fixed payment obligations.

If we raise additional funds through collaborations, strategic partnerships and alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, we may be required to delay, limit, reduce or terminate our research, product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves, obtain capital through arrangements with collaborators on terms unfavorable to us or pursue merger or acquisition strategies, all of which could adversely affect the holdings or the rights of our stockholders.

Contractual obligations and commitments

Critical accounting policies and significant judgments and use of estimates

Our condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States (GAAP). The preparation of our condensed consolidated financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

Our critical accounting policies are described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Critical Accounting Policies and Use of Estimates” in our Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the SEC on March 12, 2024. During the three months ended March 31, 2024, there were no material changes to our critical accounting policies from those previously disclosed.

Recently issued accounting pronouncements

A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 2 to our condensed consolidated financial statements appearing elsewhere in this Quarterly Report.

Emerging growth company and smaller reporting company status

The Jumpstart Our Business Startups Act of 2012 (the JOBS Act) permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. We have elected to not “opt out” of this provision and, as a result, we will adopt new or revised accounting standards at the time private companies adopt the new or revised accounting standard and will do so until such time that we either (i) irrevocably elect to “opt out” of such extended transition period or (ii) no longer qualify as an emerging growth company.

We are also a “smaller reporting company” meaning that the market value of our stock held by non-affiliates is less than $700 million and our annual revenue was less than $100 million during the most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information required under this item.

Use of Proceeds from IPO of Common Stock

On February 3, 2020, we completed the IPO of our common stock pursuant to which we issued and sold 12,174,263 shares of our common stock, including the exercise in full by the underwriters of their option to purchase up to 1,587,947 additional shares of common stock, at a public offering price of $19.00 per share.

The offer and sale of all of the shares of our common stock in our IPO were registered under the Securities Act pursuant to a registration statement on Form S-1, as amended (File No. 333-235789), which was declared effective by the SEC on January 29, 2020.

NATURE OF BUSINESS AND BASIS OF PRESENTATION	3 Months Ended
NATURE OF BUSINESS AND BASIS OF PRESENTATION	Mar. 31, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
NATURE OF BUSINESS AND BASIS OF PRESENTATION	NATURE OF BUSINESS AND BASIS OF PRESENTATION Black Diamond Therapeutics, Inc. (the Company) is a clinical-stage oncology company developing MasterKey therapies that target families of oncogenic mutations in patients with cancer. The Company was originally organized as a limited liability company in December 2014 under the name ASET Therapeutics LLC. In September 2016, the Company was converted to a corporation under the laws of the State of Delaware under the name ASET Therapeutics, Inc. The Company changed its name to Black Diamond Therapeutics, Inc. in January 2018. Since its inception, the Company has devoted substantially all of its efforts to raising capital, obtaining financing and incurring research and development costs related to the development and advancement of its product candidates identified by its Mutation-Allostery-Pharmacology (MAP) drug discovery engine. The Company is subject to risks and uncertainties common to clinical-stage companies in the biotechnology industry. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s technology will be obtained, that any products developed will obtain necessary government regulatory approval or that any products, if approved, will be commercially viable. The Company operates in an environment of rapid technological innovation and substantial competition from pharmaceutical and biotechnological companies. In addition, the Company is dependent upon the services of its employees, consultants and service providers. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales. On November 14, 2022, the Company filed a shelf registration statement on Form S-3 (the Shelf Registration Statement), with the Securities and Exchange Commission (the SEC), which covers the offering, issuance and sale of the Company’s common stock, preferred stock, debt securities, warrants and/or units of any combination thereof up to a maximum offering price of $500 million. The Company simultaneously entered into an Open Market Sale AgreementSM with Jefferies LLC (Jefferies), as sales agent, to provide for the issuance and sale by the Company of up to $150 million of its common stock from time to time through Jefferies (the ATM Program). The Shelf Registration Statement became effective on November 22, 2022. As of March 31, 2024, the Company sold 800,000 shares of its common stock pursuant to the ATM Program, resulting in gross proceeds to the Company of approximately $4.0 million ($3.9 million net of offering costs). On July 5, 2023, the Company completed an underwritten public offering (the Follow-on Offering) of 15,000,000 shares of the Company’s common stock at a price to the public of $5.00 per share. The aggregate net proceeds from the Follow-on Offering totaled approximately $71.9 million, after deducting underwriting discounts and commissions. The accompanying consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets, and the satisfaction of liabilities and commitments in the ordinary course of business. Historically, the Company has funded its operations primarily with proceeds from the sale of common stock and preferred stock. The Company has had recurring losses and negative cash flows from operations in all periods since inception and had an accumulated deficit of $435.7 million as of March 31, 2024. The Company expects to continue to generate operating losses for the foreseeable future. As of May 9, 2024, the issuance date of the condensed consolidated financial statements, the Company expects that its cash, cash equivalents and investments will be sufficient to fund its currently planned operations for at least the next 12 months from the filing date of these condensed consolidated financial statements. The Company will seek additional funding through private or public equity financings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into collaborations or other arrangements. The terms of any financing may adversely affect the holdings or the rights of the Company's stockholders. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate some or all of its research and development programs, product portfolio expansion or commercialization efforts, or reduce headcount and general and administrative costs, which could adversely affect its business prospects. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Mar. 31, 2024
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The following is a summary of significant accounting policies followed in the preparation of these condensed consolidated financial statements. Principles of consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and include the accounts of the Company and its wholly owned subsidiaries, Black Diamond Therapeutics Security Corporation and Black Diamond Therapeutics (Canada), Inc., after elimination of all significant intercompany accounts and transactions. On October 10, 2023, Black Diamond Therapeutics (Canada), Inc. was dissolved by way of voluntary dissolution. Unaudited interim financial information The condensed consolidated financial statements of the Company included herein have been prepared, without audit, pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this Quarterly Report, as is permitted by such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. In the opinion of the Company’s management, all adjustments (consisting of normal and recurring adjustments) considered necessary for a fair statement of the results for the interim periods presented have been included. Use of estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual of research and development expenses and the valuation of stock-based awards. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ from those estimates or assumptions. The Company continues to monitor the impact of global economic developments, political unrest, high inflation, disruptions in capital markets, changes in international trade relationships and military conflicts, and health crises, on all aspects of its business, and has considered the impact of these factors on estimates within its financial statements. The extent to which future developments may impact the Company’s business, results of operations or financial condition are uncertain and cannot be predicted with confidence and there may be changes to estimates in future periods. As of the date of issuance of these condensed consolidated financial statements, the Company has not experienced material business disruptions or incurred impairment losses in the carrying value of its assets as a result of these factors and is not aware of any specific related event or circumstance that would require it to update its estimates. Recently issued accounting pronouncements In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09). ASU 2023-09 requires that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate). The standard is effective for annual and interim periods beginning after December 15, 2024. Adoption of the standard requires certain changes to be made prospectively, with some changes to be made retrospectively. The adoption is not expected to have a material impact on the Company’s consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures (Topic 280) (ASU 2023-07) which requires enhanced disclosure of (1) significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or loss, (2) the amount and description of the composition of other segment items which reconcile to segment profit or loss, and (3) the title and position of the entity’s CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and allocating resources. The amendments also expand the interim segment disclosure requirements. This new guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this ASU apply retrospectively to all prior periods presented in the financial statements. The Company is in the process of assessing the impact on its financial statements from the adoption of the new guidance and the period in which the new guidance will be adopted. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (ASU 2023-06). The standard is effective for annual and interim periods beginning after December 15, 2024. Adoption of the standard requires certain changes to be made prospectively, with some changes to be made retrospectively. The adoption is not expected to have a material impact on the Company’s consolidated financial statements.

EQUITY METHOD INVESTMENT	Mar. 31, 2024
Equity Method Investments and Joint Ventures [Abstract]
EQUITY METHOD INVESTMENT	EQUITY METHOD INVESTMENT In December 2022, the Company received 9,000,000 shares of common stock in a newly formed antibody-focused precision oncology company, Launchpad Therapeutics, Inc. (Launchpad), in exchange for contributing early discovery-stage antibody programs and granting Launchpad a license to use its MAP drug discovery engine to discover, develop and commercialize large molecule therapeutics. As of the transaction date and as of March 31, 2024, the Company has a 39.1% voting interest in Launchpad and one seat on Launchpad’s Board of Directors which provide the Company with significant influence over Launchpad. The remaining voting interest in Launchpad is held by Versant Ventures and New Enterprise Associates (NEA), who are shareholders of the Company. The Company accounted for the transaction under the equity method and recorded the carrying value of the Company’s investment in Launchpad common shares of $2,250 in equity method investments in the consolidated balance sheets. The contributed in process research and development (IPR&D) had zero basis on the Company’s books prior to the transaction, therefore the Company recognized a gain on sale of IPR&D of $2,232 in the consolidated statements of operations and comprehensive loss for the year ended December 31, 2022. The Company also recognized a loss from investments in equity method investee of $1,540 in the consolidated statement of operations and comprehensive loss for the year ended December 31, 2022, associated with the Company’s proportionate share of Launchpad’s losses. The assets contributed by the Company were principally IPR&D and were not deemed a business by Launchpad, therefore the Company determined its remaining basis difference of $710 was substantially related to IPR&D and immediately expensed it. As of December 31, 2022, the carrying value of the investment in Launchpad was reduced to zero. Since the Company has no obligation to provide financing support to Launchpad, the Company is not required to record further losses exceeding the carrying value of the investment. The Company also determined that its investment in Launchpad is not material or significant to its operations or financial position. As of March 31, 2024, the carrying value of the investment in Launchpad was zero.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES The Company enters into contracts in the normal course of business with contract research organizations (CROs), contract manufacturing organizations (CMOs) and other third parties for preclinical research studies, clinical trials and testing and manufacturing services. These contracts do not contain minimum purchase commitments and are cancelable upon prior written notice. Payments due upon cancellation consist only of payments for services provided or expenses incurred, including noncancelable obligations of service providers, up to the date of cancellation. License agreements The Company is a party to license agreements, which include contingent payments. These payments will become payable if and when certain development, regulatory and commercial milestones are achieved. As of March 31, 2024, the satisfaction and timing of the contingent payments is uncertain and not reasonably estimable. Indemnification agreements In the ordinary course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with members of its board of directors and executive officers that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is, in many cases, unlimited. To date, the Company has not incurred any material costs as a result of such indemnifications. The Company is not aware of any indemnification arrangements that could have a material effect on its financial position, results of operations or cash flows, and it has not accrued any liabilities related to such obligations in its consolidated financial statements as of March 31, 2024 or December 31, 2023. Legal proceedings The Company is not currently party to and is not aware of any material legal proceedings. At each reporting date, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company expenses as incurred the costs related to such legal proceedings.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Mar. 31, 2024
Accounting Policies [Abstract]
Principles of consolidation and unaudited interim financial information	Black Diamond Therapeutics, Inc. (the Company) is a clinical-stage oncology company developing MasterKey therapies that target families of oncogenic mutations in patients with cancer. The Company was originally organized as a limited liability company in December 2014 under the name ASET Therapeutics LLC. In September 2016, the Company was converted to a corporation under the laws of the State of Delaware under the name ASET Therapeutics, Inc. The Company changed its name to Black Diamond Therapeutics, Inc. in January 2018. Since its inception, the Company has devoted substantially all of its efforts to raising capital, obtaining financing and incurring research and development costs related to the development and advancement of its product candidates identified by its Mutation-Allostery-Pharmacology (MAP) drug discovery engine. The Company is subject to risks and uncertainties common to clinical-stage companies in the biotechnology industry. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s technology will be obtained, that any products developed will obtain necessary government regulatory approval or that any products, if approved, will be commercially viable. The Company operates in an environment of rapid technological innovation and substantial competition from pharmaceutical and biotechnological companies. In addition, the Company is dependent upon the services of its employees, consultants and service providers. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales. Principles of consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and include the accounts of the Company and its wholly owned subsidiaries, Black Diamond Therapeutics Security Corporation and Black Diamond Therapeutics (Canada), Inc., after elimination of all significant intercompany accounts and transactions. On October 10, 2023, Black Diamond Therapeutics (Canada), Inc. was dissolved by way of voluntary dissolution. Unaudited interim financial information The condensed consolidated financial statements of the Company included herein have been prepared, without audit, pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this Quarterly Report, as is permitted by such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. In the opinion of the Company’s management, all adjustments (consisting of normal and recurring adjustments) considered necessary for a fair statement of the results for the interim periods presented have been included.

On October 10, 2023, Black Diamond Therapeutics (Canada), Inc. was dissolved by way of voluntary dissolution.
Use of estimates	Use of estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual of research and development expenses and the valuation of stock-based awards. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ from those estimates or assumptions.
Recently issued accounting pronouncements	Recently issued accounting pronouncements In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09). ASU 2023-09 requires that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate). The standard is effective for annual and interim periods beginning after December 15, 2024. Adoption of the standard requires certain changes to be made prospectively, with some changes to be made retrospectively. The adoption is not expected to have a material impact on the Company’s consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures (Topic 280) (ASU 2023-07) which requires enhanced disclosure of (1) significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or loss, (2) the amount and description of the composition of other segment items which reconcile to segment profit or loss, and (3) the title and position of the entity’s CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and allocating resources. The amendments also expand the interim segment disclosure requirements. This new guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this ASU apply retrospectively to all prior periods presented in the financial statements. The Company is in the process of assessing the impact on its financial statements from the adoption of the new guidance and the period in which the new guidance will be adopted. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (ASU 2023-06). The standard is effective for annual and interim periods beginning after December 15, 2024. Adoption of the standard requires certain changes to be made prospectively, with some changes to be made retrospectively. The adoption is not expected to have a material impact on the Company’s consolidated financial statements.
