Overview

Prelude is a clinical-stage precision oncology company built on a foundation of drug discovery excellence to deliver novel precision cancer medicines to underserved patients. By leveraging our core competencies in cancer biology and medicinal chemistry, combined with our clinical development capabilities, we have built an efficient, drug discovery engine and the development expertise necessary to identify compelling biological targets and create new chemical entities, or NCEs, that we advance into clinical trials. We believe our approach could result in better targeted cancer therapies. Our discovery excellence has been supported by our steady progress in creating a wholly-owned, internally developed pipeline. We also are working with our partner AbCellera Biologics Incorporated ("AbCellera") on an early-stage discovery program involving potent degraders as payloads for novel antibodies targeting tumor specific antigens. Since our inception in 2016, we have received clearance from the U.S. Food and Drug Administration, or the FDA, for multiple investigational new drug applications, or INDs, and successfully advanced several programs into clinical trials. In addition, we have other differentiated proprietary programs in various stages of preclinical development.

By focusing on developing molecules using broad mechanisms that have multiple links to oncogenic driver pathways in select patients, we have developed a diverse pipeline consisting of multiple distinct programs including kinases, targeted protein degraders, and precision antibody drug conjugates. Our pipeline is designed to serve patients with high unmet medical need, where there are limited or no treatment options. We believe we can best address these diseases by developing therapies that target primary and secondary resistance mechanisms.

We have several drug candidates in clinical development and our objective is to generate proof-of-concept clinical data to guide our future regulatory pathways to approval.

PRT3789 is a first-in-class, highly selective degrader of SMARCA2 protein, which along with SMARCA4 controls gene regulation through chromatin remodeling. Patients with SMARCA4 mutated cancer have a poor clinical prognosis. We believe this represents an area of high unmet medical need. Cancer cells with SMARCA4 mutations are dependent on SMARCA2 for their growth and survival and selectively degrading SMARCA2 induces cell death in cancer cells while sparing normal cells in preclinical models. We believe a selective SMARCA2 degrader has the potential to be of benefit in up to 10% of non-small cell lung cancer, or NSCLC, patients in the United States including many other tumor types with the SMARCA4 mutation.

PRT3789 has completed Phase 1 clinical development in patients with biomarker selected SMARCA4-mutated cancers. The Company anticipates providing updated data from the Phase 1 study by year-end 2025.

We are enrolling patients in a Phase 2 clinical trial evaluating PRT3789 in combination with KEYTRUDA (pembrolizumab) in patients with SMARCA4-mutated cancers, per the previously announced collaboration with Merck (known as MSD outside of the US and Canada).

Our discovery team has identified a series of potent, selective and orally bioavailable SMARCA2 degraders. In July 2024, we received IND clearance for the lead oral molecule, PRT7732. PRT7732 is >1000-fold selective for SMARCA2 vs. SMARCA4 and

demonstrates robust activity in SMARCA4 deficient cancer models both as monotherapy and in combination with docetaxel at well-tolerated doses. PRT7732 demonstrates good oral bioavailability and half-life suitable for once daily oral dosing. In the fourth quarter of 2024, the we initiated and enrolled the first patients in a phase 1 multi-dose escalation trial of PRT7732 (NCT06560645) in biomarker selected SMARCA4 mutated cancers. Enrollment continues to advance rapidly, and we are currently enrolling patients in the seventh dose escalation cohort (125 mg once daily). We expect to provide an initial first-in-human data update including PK/PD, safety and initial clinical activity at biologically relevant doses by year-end 2025.

As one of our first precision ADC programs we and our partner AbCellera began work on an early-stage discovery program involving potent degraders of the SMARCA family of proteins as payloads for novel antibodies targeting tumor specific antigens. Given the potent anti-tumor activity of these molecules in pre-clinical models of cancers beyond those targeted by our SMARCA2 selective degraders, we believe that these precision ADCs have the potential to extend the therapeutic utility of this class. The partnership includes up to five precision ADC targets. Under the terms of the agreement, we and AbCellera will jointly discover, develop, and commercialize products emerging from the collaboration. AbCellera will lead manufacturing activities and we will lead clinical development and global commercialization, subject to AbCellera's option to co-promote any resulting commercial products in the United States.

Outside of the AbCellera collaboration, we have discovered and optimized a number of pre-clinical precision payloads. We disclosed first data at the 36th EORTC-NCI-AACR Symposium describing preclinical proof-of-concept using a novel, potent SMARCA2/4 dual degrader as a "Precision Payload" conjugated to multiple antibodies. Prelude's SMARCA2/4 dual degraders have shown picomolar potency with potential for increased efficacy, selectivity and improved therapeutic index. Precision ADCs have potential to expand the reach of SMARCA degrader technology to cancers without SMARCA4 mutations.

Myeloproliferative neoplasms (MPN) are hematopoietic disorders arising from clonal expansion of hematopoietic stem cells (HSC) in the bone marrow. Current treatment options for MPN patients offer symptomatic benefit but fail to eliminate disease-initiating clones leading to treatment resistance and progression to secondary AML. Therapeutic approaches that can selectively eliminate disease-initiating HSCs and induce molecular remission are an unmet medical need.

Mutations in JAK2, CALR and MPL are phenotypic drivers of disease in over 90% of MPN cases. CALR mutations are the second most common driver alteration in MPN, accounting for 20-30% of all cases. Selective expression of mutant CALR on diseased cells but not on normal cells makes CALR a high value target for antibody-directed therapies in MPN.

In June, at the European Hematology Association, we delivered an oral presentation about our mutant CALR discovery efforts, including the first-in-class CALR-targeted pADCs that selectively target mutant CALR expressing cells, with the potential to achieve responses by eliminating MPN clones. These data demonstrate that a CALRxSMARCA2/4 degrader antibody conjugate can selectively degrade SMARCA2/4 in CALR mutant cells and robustly inhibit CALR-mutant cell growth in vitro and in vivo.

We have discovered and are developing a series of selective and orally bioavailable KAT6A selective degraders. We are now advancing a development candidate and remain on track to file an IND in the first half of 2026. KAT6 is a clinically validated target with promising activity in breast cancer and other solid tumors. We recently presented preclinical data from this program at the American Association for Cancer Research (AACR) 2025 Annual Meeting.

Our CDK9 candidate, PRT2527, is a potent and highly selective CDK9 inhibitor that has the potential to avoid off-target toxicities observed with other less selective CDK9 inhibitors. We presented interim phase 1 results of the dose-escalation study as part of a poster session at the 66th American Society of Hematology Annual Meeting (ASH) in the fourth quarter of 2024. PRT2527 demonstrated activity across a range of relapsed/refractory lymphoid malignancies, including patients who received prior CAR-T therapy. As previously announced, we intend to seek a partner for any future continued advancement of PRT2527.

Nasdaq Delisting Notice

On March 27, 2025, the Company received a letter (the "Bid Price Notice") from the Listing Qualifications staff (the "Staff") of The Nasdaq Stock Market LLC ("Nasdaq") indicating that, based upon the closing bid price of the Company's common stock for the prior 30 consecutive business days, the Company was not in compliance with the requirement to maintain a minimum bid price of $1.00 per share for continued listing on Nasdaq, as set forth in Nasdaq Listing Rule 5550(a)(2) (the "Minimum Bid Price Requirement").

The Bid Price Notice has no immediate effect on the continued listing status of the Company's common stock on Nasdaq, and, therefore, the Company's listing remains fully effective.

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has been provided an initial compliance period of 180 calendar days, or until September 23, 2025, in which to regain compliance with the deficiency. In order to regain compliance with the Minimum Bid Price Requirement, the closing bid price of the common stock must be at least $1.00 per share for a minimum of ten consecutive business days during this 180-day period. If the Company does not regain compliance with this requirement by September 23, 2025, the Company may be eligible for an additional 180 calendar day compliance period provided that (i) the Company meets all

other continued listing standards and (ii) the Company provides written notice to Nasdaq of its intention to cure the deficiency during the second grace period, generally by effecting a reverse stock split, if necessary.

If the Company does not regain compliance within the allotted compliance period(s), including any extensions that may be granted by Nasdaq, Nasdaq will provide notice that the Common Stock will be subject to delisting. At that time, the Company may appeal the Staff's determination to a Nasdaq Hearings Panel.

The Company intends to monitor the closing bid price of the common stock and consider its available options to resolve the noncompliance with the Minimum Bid Price Requirement.

There can be no assurance that the Company will be able to regain compliance with the Minimum Bid Price Requirement or will otherwise be in compliance with other Nasdaq listing criteria.

Components of Results of Operations

Since inception, we have devoted substantially all of our resources to developing product and technology rights, conducting research and development, organizing and staffing our company, business planning and raising capital. We have incurred recurring losses, the majority of which are attributable to research and development activities, and negative cash flows from operations. We have funded our operations primarily through the sale of convertible preferred stock, common stock and pre-funded warrants. Our net loss was $63.3 million and $66.2 million for the six months ended June 30, 2025 and 2024, respectively. As of June 30, 2025, we had an accumulated deficit of $646.9 million. Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures, and to a lesser extent, general and administrative expenditures. 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 to continue to incur significant expenses and operating losses for the foreseeable future as we advance our product candidates through all stages of development and clinical trials and, ultimately, seek regulatory approval. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials and our expenditures on other research and development activities.

Revenue

To date, we have not recognized any revenue from product sales, and we do not expect to generate any revenue 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 in connection with the discovery and development of our product candidates. We expense research and development costs as incurred, including:

expenses incurred to conduct the necessary discovery-stage laboratory work, preclinical studies and clinical trials required to obtain regulatory approval;
personnel expenses, including salaries, benefits and stock-based compensation expense for our employees engaged in research and development functions;
costs of funding research performed by third parties, including pursuant to agreements with clinical research organizations, or CROs, that conduct our clinical trials, as well as investigative sites, consultants and CROs that conduct our preclinical and nonclinical studies;
expenses incurred under agreements with contract manufacturing organizations, or CMOs, including manufacturing scale-up expenses and the cost of acquiring and manufacturing preclinical study and clinical trial materials;
fees paid to consultants who assist with research and development activities;
expenses related to regulatory activities, including filing fees paid to regulatory agencies; and
allocated expenses for facility costs, including rent, utilities, depreciation and maintenance.

We track outsourced development costs and other external research and development costs to specific product candidates on a program-by-program basis, fees paid to CROs, CMOs and research laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities. However, we do not track our internal research and development expenses on a program-by-program basis as they primarily relate to compensation, early research and other costs which are deployed across multiple projects under development.

Research and 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. We expect to continue to incur research and development expenses over the next several years related to personnel costs, including stock-based compensation, clinical trials, including later-stage clinical trials, for current and future product candidates and preparing regulatory filings for our product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel expenses, including salaries, benefits and stock-based compensation expense, for employees and consultants in executive, finance and accounting, legal, operations support, information technology and human resource functions. General and administrative expense also includes corporate facility costs not otherwise included in research and development expense, including rent, utilities, depreciation and maintenance, as well as legal fees related to intellectual property and corporate matters and fees for accounting and consulting services.

We expect to continue to incur general and administrative expense in the future to support our continued research and development activities and potential commercialization efforts. These expenses will likely include costs related to the hiring of personnel and fees to outside consultants and legal support, among other expenses. The costs associated with being a public company include expenses related to services associated with maintaining compliance with the requirements of Nasdaq and the Securities and Exchange Commission, or SEC, insurance and investor relations costs. If any of our current or future product candidates obtains U.S. regulatory approval, we expect that we would incur significantly increased expenses associated with building a sales and marketing team.

Other Income, Net

Other income, net consists primarily of interest earned on our cash equivalents and marketable securities and grant income received from the State of Delaware. We anticipate re-applying for grants from the State of Delaware from time to time as long as we maintain qualifying headcount levels.

Income Taxes

Since our inception, we have not recorded any income tax benefits for the net operating losses, or NOLs, we have incurred or for our research and development tax credits, as we believe, based upon the weight of available evidence, that it is more likely than not that all of our NOLs and tax credits will not be realized.

General and Administrative Expenses

General and administrative expenses decreased from $7.7 million for the three months ended June 30, 2024 to $6.4 million for the three months ended June 30, 2025. The decrease was primarily driven by a decrease in non-cash expense related to stock-based compensation expense. Included in general and administrative expenses for the three months ended June 30, 2025, was $1.6 million of non-cash expense related to stock-based compensation expense compared to $2.7 million for the three months ended June 30, 2024, due to the tapering off of the vesting period of prior granted options and lower valuation on more recent grants due to the decrease in our stock price.

Other Income, net

Other income, net decreased from $2.4 million for the three months ended June 30, 2024, to $1.0 million for the three months ended June 30, 2025 primarily due to lower income earned our investments due to lower balances.

Other income, net decreased from $5.3 million for the six months ended June 30, 2024, to $3.5 million for the six months ended June 30, 2025 primarily due to lower income earned our investments due to lower balances partially offset by the receipt and recognition of research and development tax credits.

Liquidity and Capital Resources

Overview

Since our inception, we have not recognized any product revenue and have incurred operating losses and negative cash flows from our operations. We have not yet commercialized any product and we do not expect to generate revenue from sales of any products for several years, if at all.

At June 30, 2025 the Company had cash, cash equivalents, restricted cash and marketable securities totaling $77.3 million. Absent additional funding, the Company believes that its cash, cash equivalents, restricted cash and marketable securities will not be sufficient to fund its operating expenses and capital expenditure requirements for at least the next twelve months from the filing date of this Quarterly Report on Form 10-Q. As a result, substantial doubt exists about our ability to continue as a going concern.

Since our inception, we have funded our operations primarily through the sale of convertible preferred stock, common stock, and pre-funded warrants. We will need to raise substantial additional capital 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 plan 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. There are no assurances that we will be successful in obtaining an adequate level of financing as and when needed to finance our operations on terms acceptable to us or at all. Any failure to raise capital as and when needed could have a negative impact on our financial condition and on our ability to pursue our business plans and strategies. If we are unable to secure adequate additional funding, we may have to significantly delay, scale back or discontinue the development and commercialization of one or more product candidates or delay our pursuit of potential in-licenses or acquisitions.

Funding Requirements

Our primary use of cash is to fund operating expenses, primarily research and development expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable, accrued expenses and prepaid expenses.

Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:

the scope, timing, progress and results of discovery, preclinical development, laboratory testing and clinical trials for our product candidates;
the costs of manufacturing our product candidates for clinical trials and in preparation for marketing approval and commercialization;
the extent to which we enter into collaborations or other arrangements with additional third parties in order to further develop our product candidates;
the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;
the costs and fees associated with the discovery, acquisition or in-license of additional product candidates or technologies;
expenses needed to attract and retain skilled personnel;
costs associated with being a public company;
the costs required to scale up our clinical, regulatory and manufacturing capabilities;
the costs of future commercialization activities, if any, including establishing sales, marketing, manufacturing and distribution capabilities, for any of our product candidates for which we receive marketing approval; and
revenue, if any, received from commercial sales of our product candidates, should any of our product candidates receive marketing approval.

We will need additional funds to meet operational needs and capital requirements for clinical trials, other research and development expenditures, and business development activities. We currently have no credit facility or committed sources of capital. Because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current and anticipated clinical studies.

In May 2024, the Company filed a shelf registration statement (the "2024 Shelf Registration Statement") with the SEC for the issuance of common stock, preferred stock, debt securities, warrants, subscription rights and units up to an aggregate amount of $400 million. The 2024 Shelf Registration statement was declared effective on June 10, 2024. The 2024 Shelf Registration statement expires in May 2027, and as of June 30, 2025 there was $400 million remaining under the 2024 Shelf Registration Statement.

In March 2023, in connection with filing a prospectus supplement to our shelf registration statement previously filed in November 2021 (the "2021 Shelf Registration Statement"), we entered into an Open Market Sales Agreement (the "Sales Agreement") with Jefferies LLC, as the sales agent, pursuant to which we may offer and sell shares of our common stock having an aggregate offering amount of up to $75.0 million. We will pay Jefferies LLC a commission rate of up to 3.0% of the aggregate gross proceeds from the sale of any shares of common stock pursuant to the Sales Agreement. In November 2024, the 2021 Shelf Registration Statement expired with respect to the shares to be sold under the Sales Agreement. Accordingly, we expect to file a prospectus supplement to the 2024 Shelf Registration Statement in order to continue to allow us to access the Sales Agreement. We have $75.0 million remaining under the Sales Agreement as of June 30, 2025.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic 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.

Emerging Growth Company and Smaller Reporting Company Status

In April 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an "emerging growth company" can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of this exemption from complying with new or revised accounting standards and, therefore, will not be subject to the same new or revised accounting

standards as other public companies that are not emerging growth companies. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Subject to certain conditions, as an emerging growth company, we may rely on certain other exemptions and reduced reporting requirements, including without limitation, exemption to the requirements for providing an auditor's attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act. We anticipate that we will no longer be an emerging growth company as of December 31, 2025 and, as a result, we will no longer be able to take advantage of reduced disclosure and other obligations that are available to emerging growth companies after that date.

We are also a "smaller reporting company," meaning that the market value of our stock held by non-affiliates is less than $700.0 million and our annual revenue is less than $100.0 million during the most recently completed fiscal year. We may continue to be a smaller reporting company after if either (i) the market value of our stock held by non-affiliates is less than $250.0 million or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700.0 million. If we remain a smaller reporting company once 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 on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.
