We have based these forward-looking statements largely on our current expectations and projections about our business, the industry in which we operate and financial trends that we believe may affect our business, financial condition, results of operations and prospects, and these forward-looking statements are not guarantees of future performance or development. These forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q and are subject to a number of risks, uncertainties and assumptions described in the section titled “Item 1A. Risk Factors” and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the United States Securities and Exchange Commission on February 29, 2024, as well as in this Quarterly Report on Form 10-Q. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events or otherwise.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report on Form 10-Q, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain, and you are cautioned not to unduly rely upon these statements.

1. Formation and Business of the Company

Organization and Liquidity

PMV Pharmaceuticals, Inc. (the “Company” or “We”) was incorporated in the state of Delaware in March 2013. Since inception, the Company has devoted substantially all of its time and efforts to performing research and development activities and raising capital. We are a precision oncology company pioneering the discovery and development of small molecule, tumor-agnostic therapies targeting p53. The Company’s headquarters are located at One Research Way, Princeton, New Jersey.

The Company is subject to risks and uncertainties common to clinical stage companies in the biotechnology industry including, but not limited to, technical risks associated with the successful research, development and manufacturing of product candidates, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. Current and future programs will require significant research and development efforts, including extensive preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel, and infrastructure. 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.

The Company has incurred net losses and negative cash flows from operations since its inception. During the three and six months ended June 30, 2024, the Company incurred a net loss of $1,213 and $16,483, respectively. For the six months ended June 30, 2024, the Company used $17,782 of cash for operations. At June 30, 2024, the Company had an accumulated deficit of $326,486. Cash, cash equivalents, and marketable securities were $212,919 as of June 30, 2024. Management expects to incur substantial additional operating losses for the next several years and may need to obtain additional debt or equity financings in order to complete development of its products, obtain regulatory approvals, launch and commercialize its products and continue research and development programs. The Company believes it has adequate cash, cash equivalents, and marketable securities to operate for the next 12 months from the date of issuance of these condensed consolidated financial statements.

2. Summary of Significant Accounting Policies

The Company’s significant accounting policies are disclosed in the audited condensed consolidated financial statements for the year ended December 31, 2023, included in the Company’s Annual Report on Form 10-K filed with the United States Securities and Exchange Commission (the “SEC”) on February 29, 2024. Since the date of those condensed consolidated financial statements, there have been no changes to its significant accounting policies.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the interim period reporting requirements of Form 10-Q and Article 10 of Regulation S-X. The condensed consolidated balance sheet as of June 30, 2024, the condensed consolidated statements of operations and comprehensive loss, condensed consolidated statements of stockholders’ equity and condensed consolidated statements of statements of cash flows for the three and six months ended June 30, 2024 and 2023 are unaudited, but, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, which we consider necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The results for any interim period are not necessarily indicative of results for the year ending December 31, 2024, or for any other subsequent interim period. The condensed consolidated balance sheet as of December 31, 2023, has been derived from our audited condensed consolidated financial statements.

The accompanying condensed consolidated financial statements include our accounts and the accounts of our wholly owned subsidiary, PMV Pharma Australia Pvt Ltd. All significant intercompany transactions and balances have been eliminated upon consolidation. These condensed consolidated financial statements are presented in United States ("U.S.") Dollars, which is also the functional currency of the Company.

Use of Estimates

The preparation of 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 disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenues and expenses during the reporting period. The Company bases its estimates and assumptions on historical experience when available and on various factors that it believes to be reasonable under the circumstances. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, research and development costs, accrued research and development costs and related prepaid expenses. Actual results could differ materially from those estimates.

Cash, Cash Equivalents, and Marketable Securities

Management considers all highly liquid investments with original maturities of three months or less to be cash equivalents.

The Company’s marketable debt securities have been classified and accounted for as available-for-sale. The Company classifies its marketable debt securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. Marketable debt securities with maturities of 12 months or less are classified as short-term and marketable debt securities with maturities greater than 12 months are classified as long-term. The Company’s marketable debt securities are carried at fair value, with unrealized gains and losses, net of taxes, reported as a component of accumulated other comprehensive loss in stockholders’ equity. Premiums and discounts on marketable debt securities are amortized into earnings over the life of the security and recorded on the interest income, net line of the income statement. For the six months ended June 30, 2024 and 2023, the Company recorded $3,004 and $1,670 of accretion, respectively.

Restricted cash as of June 30, 2024 and December 31, 2023 included a $822 deposit at the Company’s commercial bank underlying a stand-by letter of credit issued in favor of a landlord (See Note 6) and is classified in current assets.

Comprehensive Loss and Accumulated Other Comprehensive Income (Loss)

Other comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources, including unrealized gains and losses on investments and foreign currency translation gains and losses.

Leases

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the circumstances present. The Company accounts for a contract as a lease when it has the right to control the asset for a period of time while obtaining substantially all of the asset’s economic benefits. The Company determines the initial classification and measurement of its operating right-of-use (“ROU”) assets and operating lease liabilities at the lease commencement date, and thereafter if modified. The lease term includes any renewal options that the Company is reasonably certain to exercise. The Company’s policy is to not record leases with a lease term of 12 months or less on its balance sheets. The Company’s only existing leases are for office and laboratory space.

The ROU asset represents the right to use the leased asset for the lease term. The lease liability represents the present value of the lease payments under the lease. The present value of lease payments is determined by using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the Company uses its estimated secured incremental borrowing rate for that lease term.

Lease expense for operating leases is recognized on a straight-line basis over the reasonably assured lease term based on the total lease payments and is included in operating expense in the statements of operations.

Payments due under each lease agreement include fixed and variable payments. Variable payments relate to the Company’s share of the lessor’s operating costs associated with the underlying asset and are recognized when the event on which those payments are assessed occurs. Variable payments have been excluded from the lease liability and associated right-of-use asset. Neither of the Company’s leases contain residual value guarantees.

PMV Pharmaceuticals, Inc.

Notes to Condensed Consolidated Financial Statements

(unaudited)

(in thousands, except share and per share amounts)

The interest rate implicit in lease agreements is typically not readily determinable, and as such, the Company utilizes the incremental borrowing rate to calculate lease liabilities, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment.

Concentration of Credit Risk and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash, cash equivalents, and marketable securities. Cash and cash equivalents were held at primarily two financial institutions. At times, such deposits may be in excess of insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. The Company’s marketable securities are carried at fair value and include any unrealized gains and losses. Any investments with unrealized losses are considered to be temporarily impaired.

The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, rapid technological change, uncertainty of market acceptance of the product, competition from substitute products and larger companies, protection of proprietary technology, any future strategic relationships and dependence on key individuals.

Products developed by the Company require clearances from the U.S. Food and Drug Administration or other international regulatory agencies prior to commercial sales. There can be no assurance the Company’s product candidates will receive the necessary clearances.

Operating Leases

In August 2018, the Company executed two noncancelable operating leases. One lease for approximately 6,000 square feet for vivarium, laboratory and general office space in South Brunswick, New Jersey. The lease was set to expire in July 2022. In January 2022, the Company signed a lease extension for up to one additional year through July 2023, with the option to terminate upon 120 days of written notice, with an increase in base rent as per the lease extension. The lease was terminated as of June 2023. The second lease is for office space in Lexington, Massachusetts, that terminated in August 2023.

In January 2021, the Company signed a lease for 50,581 square feet of office and laboratory space at One Research Way in Princeton, New Jersey. That lease term extends through 2032, has a five-year extension option, and replaced the Company’s two existing facilities as the Company’s headquarters in March 2023. Payment under this lease will total $19,889 through May 2032. The Company received a lease incentive of $4,046 from the lessor for a buildout of laboratory, vivarium, and office space. Management estimated the timing and amounts of reimbursements and included them as a reduction of lease payments when initially measuring the lease liability and right-of-use asset upon commencement. Since the inception date of the lease, $4,046 reimbursements were received. For the six months ended June 30, 2024, $242 of reimbursements were received.

At June 30, 2024, the total compensation cost related to nonvested awards not yet recognized was $14,576. The weighted-average period over which the nonvested awards is expected to be recognized was 2.7 years.

The Company estimated the fair value of the options using the Black-Scholes options valuation model. The fair value of the options is being amortized on a straight-line basis over the requisite service period of the awards. The fair value was estimated using the following assumptions:


	Six Months Ended		Six Months Ended
	June 30,		June 30,
	2024		2023
Risk-free interest rate		3.82% - 4.69%		3.45% - 3.95%
Expected life (in years)		5.50 - 6.25		5.50 - 6.44
Dividend yield		0%		0%
Expected volatility		85.55% - 86.76%		76.5% - 77.7%

The weighted average assumptions used to estimate the fair value of stock purchase rights under the ESPP are as follows:


	Six Months Ended		Six Months Ended
	June 30,		June 30,
	2024		2023
Risk-free interest rate		5.43%		5.36%
Expected life (in years)		0.50		0.49
Dividend yield		0%		0%
Expected volatility		85.55%		76.50%

Risk Free Interest Rate: The risk-free rate is based on the U.S. Treasury yields in effect at the time of grant for periods corresponding with the expected term of the option.

Expected Term: The Company uses the simplified method to calculate expected term described in the SEC’s Staff Accounting Bulletin No. 107, which takes into account vesting term and expiration date of the options.

Dividend Yield: The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and therefore, used an expected dividend yield of zero in the valuation model.

Volatility: Volatility is based on the historical volatility of the Company's publicly traded shares for the expected term.

9. Income Taxes

The Company’s effective tax rates were 92.6% and 0% for the three months ended June 30, 2024 and 2023, respectively. The income tax provision and effective tax rate are driven primarily by the proceeds from the sale of the Company’s New Jersey tax net operating loss carryforwards and R&D tax credits.

During the three and six months ended June 30, 2024 and 2023, the Company recorded a full valuation allowance on federal and state net deferred tax assets since management does not forecast the Company to be in a taxable position in the near future.

The State of New Jersey's Technology Business Tax Certificate Program allows certain high technology and biotechnology companies to sell unused net operating loss ("NOL") carryforwards and R&D tax credits to other New Jersey-based corporate taxpayers. As of June 30, 2024, the Company received $16,176 of cash for the NOL and R&D tax credit sales related to the tax years ended December 31, 2015 to 2022. The sale of the NOLs and R&D tax credits has been recorded as an income tax benefit within the condensed consolidated statement of operations.

10. Net Loss per Share

Total consulting fees paid during the six months ended June 30, 2024 and 2023 were $87 and $42, respectively. There were no amounts owed under the consulting agreements as of June 30, 2024.

12. Restructuring

On January 18, 2024, the Company announced a restructuring plan involving the reduction of its workforce by approximately 30% of the Company's employees. Substantially all of the costs under the restructuring plan were incurred during the six months ended June 30, 2024. The remaining expected costs are not expected to be material and will be complete by September 30, 2024. The Company is taking these steps in order to streamline operations, reduce costs and preserve capital as it advances into late-stage development for its lead product candidate, PC14586.

As a result of the reduction in force, the Company incurred an aggregate non-recurring charge of $630, consisting primarily of employee severance and benefit costs associated with the restructuring. The Company has recorded these charges in research and development expenses in the accompanying condensed consolidated statement of operations based on responsibilities of the impacted employees.

The Company accounts for employee termination benefits that represent a one-time benefit in accordance with ASC Topic 420, Exit or Disposal Cost Obligations. It records such costs into expense over the employee’s future service period, if any.

The following sets forth information regarding the balances and activity associated with the Company's accrued employee severance and benefits costs (in thousands):

13. Subsequent Event

On July 16, 2024, the Company filed with the Securities and Exchange Commission a Tender Offer Statement on Schedule TO defining the terms and conditions of a one-time voluntary stock option exchange to its employees of certain options to purchase up to an aggregate of 2,820,491 shares of the Company’s common stock (the "Exchange Offer"). The completion date of the Exchange Offer will be August 13, 2024 (unless otherwise extended), at which time the new stock options will be granted to employees who tender their respective eligible stock options and elect to participate in the Exchange Offer.

On August 5,2024, the Company entered into a Lease Termination Agreement with BMR-One Research Way LLC, a Delaware limited liability company, in connection with the termination of the lease for 50,581 square feet of office and laboratory space at One Research Way in Princeton, New Jersey. Pursuant to the Termination Agreement, the Company and

Overview

We are a precision oncology company pioneering the discovery and development of small molecule, tumor-agnostic therapies targeting p53. p53 is a well-defined tumor suppressor protein known as the “guardian of the genome,” and normal, or wild-type, p53 has the ability to eliminate cancer cells. However, mutant p53 proteins can be misfolded and lose their wild-type tumor suppressing function. These p53 mutations are found in approximately half of all cancers. The field of p53 biology was established by our co-founder Dr. Arnold Levine when he discovered the p53 protein in 1979. We have leveraged more than four decades of research experience and developed unique insights into p53 to create a precision oncology platform designed to generate selective, small molecule, tumor-agnostic therapies that structurally correct specific mutant p53 proteins to restore their wild-type function. We are deploying our precision oncology platform to target p53 mutations and other p53-related cancers.

Since our formation in March 2013, we have devoted substantially all of our time and efforts to performing research and development activities and raising capital. We are not profitable and have incurred losses in each year since our inception. During the three and six months ended June 30, 2024, the Company incurred net losses of $1.2 million and $16.5 million, respectively. As of June 30, 2024, we had an accumulated deficit of $326.5 million. We do not currently have any product candidates approved for sale, and we continue to incur significant research and development and general administrative expenses related to our operations. We initiated a Phase 1/2 clinical trial, PYNNACLE, in October 2020 for our lead product candidate, PC14586 (rezatapopt). In October 2020, we were granted FDA Fast Track Designation of PC14586 for the treatment of patients with locally advanced or metastatic solid tumors that have a p53 Y220C mutation. In July 2023, we concluded our End of Phase 1 meeting with the FDA with alignment on the recommended Phase 2 dose and key elements of the single arm, Phase 2 registrational portion of the PYNNACLE study. In October 2023, we presented our updated Phase 1 clinical data for PC14586 at the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics Meeting. We are continuing to dose patients in the pivotal Phase 2 monotherapy portion of our PYNNACLE trial, and have activated over 60% of sites globally across the US, Europe and Asia-Pacific. In addition, for the separate Phase 1b arm of the PYNNACLE trial, which combines rezatapopt with KEYTRUDA® (pembrolizumab) in collaboration with Merck and Co, we have updated patient eligibility criteria to exclude patients with KRAS single-nucleotide variant, consistent with the Phase 2 monotherapy eligibility criteria, and are continuing to identify the optimal combination dose. We expect to provide interim data on the Phase 2 monotherapy registrational portion of the PYNNACLE trial by mid-2025.

We expect that our operating expenses will increase significantly as we advance our product candidates through preclinical and clinical development, seek regulatory approval, and prepare for and, if approved, proceed to commercialization; acquire, discover, validate, and develop additional product candidates; obtain, maintain, protect, and enforce our intellectual property portfolio; and hire additional personnel. Furthermore, we have incurred and will continue to incur additional costs associated with operating as a public company that we did not experience as a private company. We expect to continue to incur significant losses for the foreseeable future.

Our ability to generate product revenue will depend on the successful development, regulatory approval, and eventual commercialization of one or more of our product candidates. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through private or public equity or debt financings, collaborative, or other arrangements with corporate sources, or through other sources of financing. Adequate funding may not be available to us

on acceptable 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 our product candidates.

We plan to continue to use third-party service providers, including clinical research organizations, or CROs, and contract manufacturing organization, or CMOs, to carry out our preclinical and clinical development and to manufacture and supply the materials to be used during the development and commercialization of our product candidates. We do not currently have a sales force.

Components of 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

Our research and development expenses consist primarily of costs incurred to conduct research, such as the discovery and development of our product candidates as well as the development of future product candidates. Research and development expenses include personnel costs, including stock-based compensation expense, third-party contractor services, laboratory materials and supplies, and depreciation and maintenance of research equipment. We expense research and development costs as they are incurred.

We do not allocate our costs by product candidate or development program, as a significant amount of research and development expenses include compensation costs, materials, supplies, depreciation on and maintenance of research equipment, and the cost of services provided by outside contractors, which are not tracked by product candidate or development program. In particular, with respect to internal costs, several of our departments support multiple product candidate research and development programs, and therefore the costs cannot be allocated to a particular product candidate or development program. Substantially all of our research and development costs are associated with our lead product candidate, PC14586 (rezatapopt). We initiated a Phase 1/2 clinical trial in October 2020 for our lead product candidate, PC14586. In October 2020, we were granted FDA Fast Track Designation of PC14586 for the treatment of patients with locally advanced or metastatic solid tumors that have a p53 Y220C mutation. In October 2023, we presented our updated Phase 1 clinical data for PC14586 at the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics Meeting. We are continuing to dose patients, and have activated over 60% of sites globally across the US, Europe and Asia-Pacific, in the registrational, tumor-agnostic PYNNACLE Phase 2 trial of PC14586 in patients with advanced solid tumors harboring a TP53 Y220C mutation and KRAS wild-type (WT). In addition, for the separate Phase 1b arm of the PYNNACLE trial, which combines rezatapopt with KEYTRUDA® (pembrolizumab) in collaboration with Merck and Co., we have updated patient eligibility criteria to exclude patients with KRAS single-nucleotide variant, consistent with the Phase 2 monotherapy eligibility criteria, and are continuing to identify the optimal combination dose. We expect to provide interim data on the Phase 2 monotherapy registrational portion of the PYNNACLE trial by mid-2025.

We expect our research and development expenses to increase substantially in absolute dollars in the future as we advance our product candidates into and through clinical trials and pursue regulatory approval of our product candidates. The process of conducting the necessary clinical research to obtain regulatory approval is costly and time-consuming. The actual probability of success for our product candidates may be affected by a variety of factors including: the safety and efficacy of our product candidates, clinical data, investment in our clinical program, the ability of any future collaborators to successfully develop our licensed product candidates, competition, manufacturing capability, and commercial viability. We may never succeed in achieving regulatory approval for any of our product candidates. As a result of the uncertainties discussed above, we are unable to determine the duration and completion costs of our research and development projects.

General and Administrative Expenses

General and administrative expenses include personnel costs, expenses for outside professional services and other allocated expenses. Personnel costs consist of salaries, bonuses, benefits, and stock-based compensation. Outside professional services consist of legal, accounting and audit services and other consulting fees. Allocated expenses consist of rent expense related to our office and research and development facilities. We also expect to increase our general and administrative

expenses as we advance our product candidates through preclinical research and development, manufacturing, clinical development, and commercialization.

Total	$	14,628	$	13,843	$	785

Research and development expenses were $14.6 million for the three months ended June 30, 2024, compared to $13.8 million for the three months ended June 30, 2023. The increase of $0.8 million, compared to the three months ended June 30, 2023, was primarily due to the following:

•

$0.4 million decrease in research expenses, largely driven by decreased contractual research organization costs;

•

$1.3 million increase in development expenses associated with advancing our lead product candidate, PC14586, through the Phase 1/2 clinical trial; and

•

$0.1 million decrease in expenses for personnel related costs and stock-based compensation, primarily driven by decreased headcount.

General and Administrative Expenses

General and administrative expenses were $5.5 million for the three months ended June 30, 2024, compared to $6.3 million for the three months ended June 30, 2023. The decrease of $0.8 million, compared to the three months ended June 30, 2023, was primarily due to following:

•

$0.6 million decrease in personnel expenses driven by a decrease in headcount, $0.3 million decrease in facility and equipment expenses due to expiration of three leases, and $0.2 million decrease in director and officer insurance fees, offset by a $0.3 million increase in finance and legal support expenses

Interest Income, Net

Interest income, net primarily consists of interest income from our interest-bearing cash, cash equivalents and marketable securities and interest costs related to accretion and amortization of discounts and premiums on marketable securities. Interest income, net was $2.8 million for the three months ended June 30, 2024. The increase of $0.1 million compared to the three months ended June 30, 2023, is driven by increased interest rates from cash and investments in marketable securities and U.S treasuries during the three months ended June 30, 2024.

Income Tax Benefit

As of June 30, 2024, the Company received $16,176 of cash for the NOL and R&D tax credit sales related to the tax years ended December 31, 2015 to 2020. The sale of the NOLs and R&D tax credits have been recorded as an income tax benefit within the condensed consolidated statement of operations.

Research and development expenses were $27.8 million for the six months ended June 30, 2024, compared to $28.9 million for the six months ended June 30, 2023. The decrease of $1.1 million, compared to the six months ended June 30, 2023, was primarily due to the following:

•

$1.6 million decrease in research and development expenses, largely driven by decreased contractual research organization costs; offset by

•

$0.5 million increase in expenses for personnel related costs and stock-based compensation as a result of the non-recurring charges from our reduction in force initiated in January 2024.

General and Administrative Expenses

General and administrative expenses were $10.6 million for the six months ended June 30, 2024, compared to $12.7 million for the six months ended June 30, 2023. The decrease of $2.1 million, compared to the six months ended June 30, 2023, was primarily due to following:

•

$1.0 million decrease in personnel expenses driven by a decrease in headcount, $1.1 million decrease in facility and equipment expenses due to expiration of three leases, and $0.3 million decrease in director and officer insurance fees and legal expenses, offset by a $0.3 million increase in finance and legal support expenses.

Interest Income, Net

Interest income, net primarily consists of interest income from our interest-bearing cash, cash equivalents and marketable securities and interest costs related to accretion and amortization of discounts and premiums on marketable securities. Interest income, net was $5.8 million for the six months ended June 30, 2024. The increase of $0.7 million compared to the six months ended June 30, 2023, is driven by increased interest rates from cash and investments in marketable securities and U.S treasuries during the six months ended June 30, 2024.

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. As of June 30, 2024, we had cash, cash equivalents, and marketable securities of $212.9 million and an accumulated deficit of $326.5 million.

We have a shelf registration statement on Form S-3 on file with the SEC, which registers the offering, issuance, and sale of up to $200 million of various equity and debt securities and up to $150 million of common stock pursuant to our at-the-market equity offering program, dated October 4, 2021, or the ATM Program. During the three and six months ended June 30, 2024, the Company did not sell any shares of its common stock under the ATM Program. As of June 30, 2024, we have approximately $113.8 million remaining in gross proceeds available for future issuances of common stock under the ATM Program.

Contractual Obligations and Commitments

We enter into contracts in the normal course of business with CROs and other vendors to assist in the performance of our research and development activities and other services and products for operating purposes. These contracts generally provide for termination on notice, and therefore are cancelable contracts and not included in the table of contractual obligations and commitments.

In January 2021, we signed a lease for 50,581 square feet of office and laboratory space at One Research Way in Princeton, New Jersey. That lease term extends through 2032 and has a five-year extension option. Amounts related to future lease payments as of June 30, 2024, totaled $14.3 million, with $1.8 million to be paid within the next 12 months.

Plan of Operation and Future Funding Requirements

We use our capital resources primarily to fund operating expenses, mainly research and development expenditures. On January 18, 2024, we announced a restructuring plan involving the reduction of our workforce by approximately 30% of our employees. Substantially all of the costs under the restructuring plan were incurred during the six months ended June 30, 2024. The remaining expected costs are not expected to be material and will be complete by September 30, 2024. As announced, we are taking these steps in order to streamline operations, reduce costs and preserve capital as we advance our lead candidate, PC14586, into late-stage development. At this time, due to the inherently unpredictable nature of preclinical and clinical development, we cannot reasonably estimate the costs we will incur and the timelines that will be required to complete development, obtain marketing approval and commercialize our current product candidates or any future product candidates, if at all. For the same reasons, we are also unable to predict when, if ever, we will generate revenue from product sales or whether, or when, if ever, we may achieve profitability. Clinical and preclinical development timelines, the probability of success, and development costs can differ materially from expectations. In addition, we cannot forecast which product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements.

Due to our significant research and development expenditures, we have generated substantial operating losses in each period since inception. We have incurred an accumulated deficit of $326.5 million through June 30, 2024. We expect to incur substantial additional losses in the future as we expand our research and development activities. For the six months ended June 30, 2024 and 2023, our cash operating expenditures were $17.8 million and $27.9 million, respectively. Based on our research and development plans, we expect that our cash, cash equivalents and marketable securities as of June 30, 2024 will be sufficient to fund our operations to the end of 2026.

We have based this estimate on assumptions that may prove to be wrong, however, and we could use our capital resources sooner than we expect.

The timing and amount of our operating expenditures will depend largely on:

•

the timing and progress of preclinical and clinical development activities;

•

the number and scope of preclinical and clinical programs we decide to pursue;

•

the timing and amount of milestone payments we may receive under any future collaboration agreements;

•

our ability to maintain future licenses and research and development programs and to establish new collaboration and/or in-licensing arrangements;

•

the costs involved in prosecuting and enforcing patent and other intellectual property claims;

•

the cost and timing of regulatory approvals;

•

the costs involved in implementing our announced reduction in force and related reorganization; and

•

our efforts to manage our office and laboratory headquarters, enhance operational systems and hire additional personnel to support development of our product candidates and satisfy our obligations as a public company.

Until such time, if ever, as we can generate substantial revenue from product sales, we expect to fund our operations and capital funding needs through equity and/or debt financing. We may also consider entering into collaboration arrangements or selectively partnering for clinical development and commercialization. The sale of additional equity would result in additional dilution to our stockholders. The incurrence of debt financing would result in debt service obligations and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations or our ability to incur additional indebtedness or pay dividends, among other items. If we raise additional funds through governmental funding, 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 not able to secure adequate additional funding, we may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. Any of these actions could materially and adversely affect our business, financial condition, results of operations and prospects.

Cash Flows

The following table summarizes our cash flows for the period indicated (in thousands):


	Six Months Ended June 30,
	2024 (Unaudited)			2023 (Unaudited)
Cash used in operating activities	$	(17,782	)	$	(27,913	)

Impact of exchange rates on cash, cash equivalents, and restricted cash		(28	)		—
Net increase (decrease) in cash and cash equivalents	$	10,820		$	(40,088	)

Operating Activities

Net cash used in operating activities for the six months ended June 30, 2024, was $17.8 million, which consisted primarily of net loss of $16.5 million partially offset by non-cash charges of $2.9 million. Changes in our net operating assets decreased operating cash by $4.2 million. The non-cash charges primarily consisted of stock-based compensation of $5.4 million, accretion of discounts on marketable securities of $3.0 million, depreciation of $0.7 million, and non-cash lease income of $0.2 million. The change in our net operating assets and liabilities was primarily due to an increase in prepaid expenses and other assets, and a decrease in outstanding payables and accrued expenses.

Net cash used in operating activities for the six months ended June 30, 2023, was $27.9 million, which consisted primarily of net loss of $36.6 million partially offset by non-cash charges of $4.8 million. Changes in our net operating assets increased operating cash by $3.9 million. The non-cash charges primarily consisted of stock-based compensation of $6.1 million, accretion of premiums on marketable securities of $1.7 million, depreciation of $0.5 million, and non-cash lease income of $0.2 million. The change in our net operating assets and liabilities was primarily due to a decrease in prepaid expenses and other assets, and an increase in outstanding payables and accrued expenses.

Investing Activities

Our investing activities provided $28.5 million of cash during the six months ended June 30, 2024, which consisted primarily of maturities of marketable securities of $100.5 million, partially offset by purchases of marketable securities of $71.4 million, along with purchase of property and equipment of $0.6 million.

Our investing activities used $14.3 million of cash during the six months ended June 30, 2023, which consisted primarily of purchases of marketable securities of $129.6 million, along with purchase of property and equipment of $0.7 million, partially offset by maturities of marketable securities of $116.0 million.

Financing Activities

Our financing activities provided $0.1 million of cash during the six months ended June 30, 2024. This consisted of $0.1 million of proceeds from the exercise of stock options.

Our financing activities provided $2.1 million of cash during the six months ended June 30, 2023. This consisted of $2.0 million of common stock issued under the ATM Program, net of issuance costs, and $0.1 million of proceeds from the exercise of stock options.

Critical Accounting Policies and Significant Judgments and Estimates

The preparation of our condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and judgments that affect the amounts reported in those condensed consolidated financial statements and accompanying notes. Although we believe that the estimates we use are reasonable, due to the inherent uncertainty involved in making those estimates, actual results reported in future periods could differ from those estimates.

We believe that the accounting policies described below involve a high degree of judgment and complexity. Accordingly, these are the policies we believe are the most critical to aid in fully understanding and evaluating our financial condition and results of our operations. During the six-month period ended June 30, 2024, there were no material changes to our critical accounting policies from those described in our audited condensed consolidated financial statements for the year ended December 31, 2023, included in our Annual Report on Form 10-K filed with the SEC on February 29, 2024, except as noted below.

Research and Development Costs, Accrued Research and Development Costs and Related Prepaid Expenses

Research and development costs are expensed as incurred. Research and development expenses consist principally of personnel costs, including salaries, stock-based compensation and benefits for employees, third-party license fees and other operational costs related to our research and development activities, including sourcing of raw materials and manufacturing of our product candidates, allocated facility-related expenses and external costs of outside vendors, and other direct and indirect costs. Non-refundable research and development advance payments are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or services are performed.

As part of the process of preparing our condensed consolidated financial statements, we are required to estimate our accrued research and development expenses. This process involves reviewing open contracts and purchase orders, communicating with our applicable 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. The majority of our service providers invoice us in arrears for services performed, on a pre-determined schedule or when contractual milestones are met; however, some require advance payments. We make estimates of our accrued expenses as of each balance sheet date in the condensed consolidated financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of the estimates with the service providers and make adjustments if necessary. Examples of estimated accrued research and development expenses include fees paid to:

•

vendors, including research laboratories, in connection with preclinical development activities;

•

CROs and investigative sites in connection with preclinical studies and clinical trials; and

•

CMOs in connection with drug substance and drug product formulation of preclinical studies and clinical trial materials.

We base our expenses related to preclinical studies and clinical trials on our estimates of the services received and efforts expended pursuant to quotes and contracts with multiple research institutions and CROs that supply, conduct and manage preclinical studies and clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, we adjust the accrual or the prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in reporting amounts that are too high or too low in any particular period. To date, there have not been any material adjustments to our prior estimates of accrued research and development expenses.

Recent Accounting Pronouncements

For a description of recent accounting pronouncements, see Note 2 of the notes to our unaudited condensed consolidated financial statements for the six months ended June 30, 2024 included elsewhere in this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risks in the ordinary course of our business. These risks primarily relate to interest rate risks.

We had cash, cash equivalents, and marketable securities of $212.9 million and restricted cash of $0.8 million as of June 30, 2024. The Company’s cash equivalents consist of interest-bearing U.S. treasury securities, money market funds, and corporate debt securities. Our exposure due to changes in interest rates is not material due to the nature and amount of our money-market funds and marketable securities.

We are not currently exposed to significant market risk related to changes in foreign currency exchange rates; however, we may contract with foreign vendors that are located outside the United States in the future. This may subject us to fluctuations in foreign currency exchange rates in the future.

Item 4. Controls and Procedures.

We maintain disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in our Securities Exchange Act of 1934, as amended reports is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We carry out a variety of ongoing procedures, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, to evaluate the effectiveness of the design and operation of our disclosure controls and procedures. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2024.

There have not been any changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

We are not currently involved in any litigation or legal proceedings that, in management’s opinion, are likely to have any material adverse effect on the Company.

Item 1A. Risk Factors.

There have been no material changes to the Company’s risk factors as set forth in Part I, Item 1A of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as filed with the SEC on February 29, 2024, as supplemented by our Quarterly Report on Form 10-Q for the quarter ended March 31, 2024, as filed with the SEC on May 9, 2024. You should carefully review and consider the information regarding certain factors which could materially affect our business, financial condition or future results set forth under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as filed with the SEC on February 29, 2024, and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2024, as filed with the SEC on May 9, 2024.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

(a) Unregistered Sales of Equity Securities

None.

(b) Use of Proceeds

Our registration statement on Form S-1 (File No. 333-248627) relating to the IPO was declared effective by the SEC. The IPO closed on September 25, 2020 at which time we sold 13,529,750 shares of common stock (including the exercise in full by the underwriters of their option to purchase an additional 1,764,750 shares of common stock) at a public offering price of $18.00 per share. We received net proceeds from the IPO of approximately $223.2 million, after deducting the underwriting discounts and commissions of approximately $17.0 million and estimated offering related expenses of approximately $3.3 million. No offering expenses were paid or payable, directly, or indirectly, to our directors, officers, or persons owning 10% or more of any class of equity securities or to our affiliates. Goldman Sachs & Co. LLC, BofA Securities, Cowen, and Evercore ISI acted as joint book-running managers for the offering.

There has been no material change in the planned use of proceeds from the IPO from that described in the prospectus filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act on September 24, 2020.

We have a shelf registration statement on Form S-3 (File No. 333-260012), which was declared effective by the SEC on April 28, 2022. The shelf registration statement consists of (i) a base prospectus pursuant to which we may offer and sell, from time to time, up to $200 million of shares of our common stock, shares of our preferred stock, various series of debt securities and warrants to purchase any of such securities in one or more registered offerings, and (ii) a prospectus supplement pursuant to which we may offer and sell, from time to time, up to $150 million of shares of common stock in "at-the-market" offerings. During the three and six months ended June 30, 2024, the Company did not sell any shares of its common stock under the ATM Program. As of June 30, 2024, we have approximately $113.8 million remaining in gross proceeds available for future issuances of common stock under the ATM Program. There has been no material change in the planned use of proceeds as described in the shelf registration statement. None of the offering expenses were paid or payable, directly, or indirectly, to our directors, officers, or persons owning 10% or more of any class of equity securities or to our affiliates.

None.

Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Jun. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the interim period reporting requirements of Form 10-Q and Article 10 of Regulation S-X. The condensed consolidated balance sheet as of June 30, 2024, the condensed consolidated statements of operations and comprehensive loss, condensed consolidated statements of stockholders’ equity and condensed consolidated statements of statements of cash flows for the three and six months ended June 30, 2024 and 2023 are unaudited, but, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, which we consider necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The results for any interim period are not necessarily indicative of results for the year ending December 31, 2024, or for any other subsequent interim period. The condensed consolidated balance sheet as of December 31, 2023, has been derived from our audited condensed consolidated financial statements. The accompanying condensed consolidated financial statements include our accounts and the accounts of our wholly owned subsidiary, PMV Pharma Australia Pvt Ltd. All significant intercompany transactions and balances have been eliminated upon consolidation. These condensed consolidated financial statements are presented in United States ("U.S.") Dollars, which is also the functional currency of the Company.
Use of Estimates	Use of Estimates The preparation of 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 disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenues and expenses during the reporting period. The Company bases its estimates and assumptions on historical experience when available and on various factors that it believes to be reasonable under the circumstances. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, research and development costs, accrued research and development costs and related prepaid expenses. Actual results could differ materially from those estimates.
Cash, Cash Equivalents, and Marketable Securities	Cash, Cash Equivalents, and Marketable Securities Management considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company’s marketable debt securities have been classified and accounted for as available-for-sale. The Company classifies its marketable debt securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. Marketable debt securities with maturities of 12 months or less are classified as short-term and marketable debt securities with maturities greater than 12 months are classified as long-term. The Company’s marketable debt securities are carried at fair value, with unrealized gains and losses, net of taxes, reported as a component of accumulated other comprehensive loss in stockholders’ equity. Premiums and discounts on marketable debt securities are amortized into earnings over the life of the security and recorded on the interest income, net line of the income statement. For the six months ended June 30, 2024 and 2023, the Company recorded $3,004 and $1,670 of accretion, respectively. Restricted cash as of June 30, 2024 and December 31, 2023 included a $822 deposit at the Company’s commercial bank underlying a stand-by letter of credit issued in favor of a landlord (See Note 6) and is classified in current assets.
Comprehensive Loss and Accumulated Other Comprehensive Income (Loss)	Comprehensive Loss and Accumulated Other Comprehensive Income (Loss) Other comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources, including unrealized gains and losses on investments and foreign currency translation gains and losses.
Leases	Leases At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the circumstances present. The Company accounts for a contract as a lease when it has the right to control the asset for a period of time while obtaining substantially all of the asset’s economic benefits. The Company determines the initial classification and measurement of its operating right-of-use (“ROU”) assets and operating lease liabilities at the lease commencement date, and thereafter if modified. The lease term includes any renewal options that the Company is reasonably certain to exercise. The Company’s policy is to not record leases with a lease term of 12 months or less on its balance sheets. The Company’s only existing leases are for office and laboratory space. The ROU asset represents the right to use the leased asset for the lease term. The lease liability represents the present value of the lease payments under the lease. The present value of lease payments is determined by using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the Company uses its estimated secured incremental borrowing rate for that lease term. Lease expense for operating leases is recognized on a straight-line basis over the reasonably assured lease term based on the total lease payments and is included in operating expense in the statements of operations. Payments due under each lease agreement include fixed and variable payments. Variable payments relate to the Company’s share of the lessor’s operating costs associated with the underlying asset and are recognized when the event on which those payments are assessed occurs. Variable payments have been excluded from the lease liability and associated right-of-use asset. Neither of the Company’s leases contain residual value guarantees. The interest rate implicit in lease agreements is typically not readily determinable, and as such, the Company utilizes the incremental borrowing rate to calculate lease liabilities, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment.
Concentration of Credit Risk and Other Risks and Uncertainties	Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash, cash equivalents, and marketable securities. Cash and cash equivalents were held at primarily two financial institutions. At times, such deposits may be in excess of insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. The Company’s marketable securities are carried at fair value and include any unrealized gains and losses. Any investments with unrealized losses are considered to be temporarily impaired. The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, rapid technological change, uncertainty of market acceptance of the product, competition from substitute products and larger companies, protection of proprietary technology, any future strategic relationships and dependence on key individuals. Products developed by the Company require clearances from the U.S. Food and Drug Administration or other international regulatory agencies prior to commercial sales. There can be no assurance the Company’s product candidates will receive the necessary clearances. If the Company is denied clearance, clearance is delayed or it is unable to maintain clearance, it could have a materially adverse impact on the Company.
