Overview

We are a clinical stage biotechnology company discovering and developing precision medicines utilizing our proprietary Generative Phosphoproteomics Acrivon Predictive Precision Proteomics, or AP3, platform designed to interpret and quantify compound specific, drug-regulated pathway activity levels inside the intact cell in an unbiased and actionable manner. Our approach is designed to overcome the limitations of genetics-based precision medicine. We do this by using AP3 to discover and develop our pipeline of innovative oncology drug candidates. AP3 is engineered to measure compound-specific effects on the entire tumor cell protein, signaling network and drug-induced resistance mechanisms in an unbiased manner and is modality and disease agnostic. These distinctive capabilities enable AP3's direct application for drug design optimization for monotherapy activity, the identification of rational drug combinations, and the creation of drug-specific proprietary OncoSignature companion diagnostics that are used to identify the patients most likely to benefit from our drug candidates.

We are currently focused on oncology and advancing our pipeline of preclinical and clinical-stage small molecule inhibitors. ACR-368 (also known as prexasertib), which is a selective small molecule inhibitor targeting CHK1 and partially CHK2, is in a potentially registrational Phase 2 trial focusing on endometrial cancer. ACR-2316 is a novel, potent and selective inhibitor of WEE1 and PKMYT1 that is currently being advanced in Phase 1 studies for selected solid tumor types predicted sensitive by AP3. In addition, we are advancing a preclinical program directed against an undisclosed cell cycle regulatory target, with a development candidate nomination anticipated in 2025.

The ACR-368 registrational-intent multi-center Phase 2B trial is based on OncoSignature-predicted sensitivity to ACR-368 in endometrial cancer patients, a tumor type predicted to be sensitive to ACR-368 through preclinical AP3-based indication finding, and not previously evaluated in past clinical trials. Our ACR-368 OncoSignature test, which has not yet obtained regulatory approval, has been extensively evaluated in preclinical studies, including in two separate, blinded, prospectively-designed studies on pretreatment tumor biopsies collected from patients with ovarian cancer treated with ACR-368 in past Phase 2 clinical trials conducted by Lilly and at the National Cancer Institute providing evidence of robust enrichment of responders through our method. Moreover, the ongoing registrational-intent trial in endometrial cancer showed initial validation of the ACR-368 OncoSignature for prospective patient selection.

In May 2023, ACR-368 was granted Fast Track designation from the FDA for the investigation of ACR-368 monotherapy for patients with OncoSignature-positive, or BM+, endometrial cancer. In January 2025, the ACR-368 OncoSignature test was granted Breakthrough Device Designation for the identification of endometrial cancer patients who may benefit from treatment with ACR-368. These designations reflect the FDA's determination that the device is reasonably expected to provide for more effective treatment or diagnosis of life-threatening or irreversibly debilitating human disease or conditions.

At ESMO 2024 (September 14, 2024 R&D event and press release), we reported that endometrial cancer was our prioritized indication, as it represents the first potential registrational opportunity for ACR-368. We remain confident in this strategy based on emerging clinical data, competitive positioning given limited treatment options, and the strong commercial opportunity in both second- and front-line settings. Our blinded KOL market research estimates that there are approximately 27,000 U.S. patients annually in the second-line setting for high-grade endometrial cancer.

An interim data extract from the EDC clinical database was done on February 25, 2025, including 20 BM+ endometrial cancer patients treated with ACR-368 monotherapy and 38 OncoSignature-negative, or BM-, treated with ACR-368 plus ultra low-dose gemcitabine, or ULDG, that were efficacy-evaluable by RECIST (2 BM- had treatment discontinued without scan). All BM+ patients had progressed after prior platinum-based chemotherapy and prior anti-PD-1, and the median and mean prior lines of therapy for these patients were 2 and 2.6, respectively. Based on available EDC data, a majority of these BM+ patients were refractory to the last prior line of therapy, with aggressive, generally heavily pre-treated tumors: 12 had refractory disease (best overall response of progressive

disease in the last prior line of therapy), 6 had relapsed disease, and 2 unknown. Amongst these 20 BM+ patients, 15 were either serous or carcinosarcomas, 13 were pMMR (2 dMMR, 5 not tested), and 11 p53 mutated (3 wild-type; 6 unknown). In patients that had relapsed after the prior line of therapy (N=6), the confirmed overall response rate, or ORR, was 50% and the disease control rate, or DCR, was 100%. Amongst the 12 patients with tumors refractory to the last prior line of therapy (ORR = 0%) we observed meaningful ACR-368 clinical activity with a confirmed ORR of 33% and DCR of 75%. The ACR-368 OncoSignature accurately identified patients whose tumors are sensitive to ACR-368, with 80% of BM+ patients demonstrating tumor shrinkage. Among all 20 BM+ patients the confirmed ORR was 35% and the DCR was 80% with median duration of response >5.6 months (not yet reached). Overall, we observed significant anti-tumor activity and disease control in BM+ patients with aggressive, refractory tumors that did not respond at all (0 % ORR) to the last line of prior therapy, and with a confirmed ORR more than double (35%) the best ORR observed in the last prior line of therapy (15%) for all BM+ patients.

We have previously confirmed in preclinical studies that ULDG sensitizes both BM- and BM+ tumors to ACR-368, as predicted by the AP3 platform, and this is consistent with an upregulation of the ACR-368 OncoSignature biomarkers in both human tumor cell lines and in human tumor xenograft mouse models after ULDG treatment. We now have obtained further evidence of such OncoSignature biomarker upregulation in human patient tumors based on serial pre- and post-ULDG biopsies in an ongoing Investigator-Initiated Trial at the Moffitt Cancer Center in patients with head and neck cancer. Consistent with this preclinical and now clinical evidence of sensitization by ULDG in BM- patients, we are continuing to explore the combination of ACR-368 with ULDG in our ongoing endometrial cancer trial. Preliminary analyses of the 38 BM- patients, who are heavily pretreated (median of 3 prior lines of therapy) show a confirmed ORR of ~13% with the ACR-368 + ULDG combination, which is comparable to the best ORR in the last prior line of therapy (median = 3) in these patients, which was 17%. Based on the totality of the preclinical and observed clinical data, we believe this supports significant ULDG sensitization to ACR-368 in BM- patients. To study this, in July 2025 we initiated a Phase 2 single arm trial of ACR-368 with ULDG sensitization, in a biomarker unselected ("all comer") population in 2ndline endometrial cancer patients.

Based on additional preclinical drug combination and AP3 mechanistic studies, we believe that ACR-368 may exhibit broad synergy with numerous other chemotherapeutic agents, in particular topoisomerase inhibitor which is one of the most commonly incorporated payloads in antibody-drug conjugates, or ADCs. This supports the potential for ACR-368 treatment benefit in combination with such ADCs. We plan on conducting additional preclinical and clinical evaluations to further assess this synergistic potential and its utility in combination regimens.

We are also leveraging our proprietary AP3 precision medicine platform for streamlined drug discovery through AP3-based drug optimization in intact cells and co-crystallography and to develop our internally-discovered pipeline programs. ACR-2316, our second clinical stage asset, is a novel, selective WEE1/PKMYT1 inhibitor designed using AP3 for superior single-agent activity through strong activation of not only CDK1 and CDK2 but also of PLK1 to drive pro-apoptotic cell death, as observed in preclinical studies against benchmark inhibitors. Utilizing AP3, we were able to advance ACR-2316 to first dosing in a Phase 1 trial in 15 months, with dosing initiated in the third quarter of 2024. The Phase 1 study will assess the safety and tolerability of ACR-2316. Additionally, the study will seek to establish the pharmacokinetic, or PK, profile, evaluate preliminary anti-tumor activity and determine the recommended Phase 2 monotherapy dose. Dose optimization is being guided by drug target engagement in alignment with the FDA's Project Optimus. We anticipate providing a clinical data update in the second half of 2025. Based on PK analysis we have observed encouraging approximate dose proportionality in the first two dose level, or DL, cohorts. Moreover, using our internal MS-based AP3 profiling to support the clinical trial of ACR-2316, we have observed significant drug target engagement in peripheral blood mononuclear cells already at DL 1. In addition, initial clinical activity with tumor shrinkage has been observed across several solid tumor types predicted to be sensitive to ACR-2316 by AP3 during our dose escalation phase, including a confirmed partial response already at DL3, which is well below the anticipated RP2D. In addition, we are advancing a preclinical program directed against an undisclosed cell cycle regulatory target, with a development candidate nomination anticipated in 2025.

We have established the Generative Phosphoproteomics AP3 platform which is designed to allow us to interpret and quantify the drug-regulated pathway activity levels inside the intact cell. The Generative Phosphoproteomics AP3 platform is comprised of a growing suite of powerful, internally developed tools, including the AP3 Interactome, the AP3 Kinase Substrate Relationship Predictor, the AP3 Data Portal, designed to enable the conversion of multimodal data into structured data amenable for generative AI analyses, and the AP3 Chatbot. Through the combination of these distinctive tools and capabilities, the platform enables us to go beyond current AI target-centric drug discovery and to rapidly design highly differentiated compounds with optimal, desirable pathway effects on the intracellular signaling network to mechanistically address the underlying molecular cause of disease. The integrated analyses of our AP3generated proprietary datasets through a unified computational interface enables streamlined transition from preclinical to the clinical phase, as exemplified by the development of ACR-2316.

Since our inception in 2018, we have devoted substantially all of our resources toward conducting discovery and research activities, organizing and staffing our company, business planning, acquiring and internally discovering drug candidates, establishing and protecting our intellectual property portfolio, developing and progressing ACR-368 and the ACR-368 OncoSignature, preparing for

and conducting preclinical studies and clinical trials, establishing arrangements with third parties for the manufacture of ACR-368, the ACR-368 OncoSignature and component materials, advancing our internal co-crystallography-driven, AP3-enabled preclinical programs, conducting preclinical studies, establishing arrangements with third parties for the manufacture of ACR-2316, and initiating a Phase 1b clinical trial for ACR-2316, as well as raising capital. We do not have any drug candidates approved for sale and have not generated any revenue from drug sales.

Since inception, we have funded our operations primarily with proceeds from the sales of shares of our convertible preferred stock, the issuance of convertible notes, our IPO and concurrent private placement. Upon the closing of our IPO on November 17, 2022, only common stock remains issued and outstanding. In addition, on April 8, 2024, we entered into a Private Investment in Public Equity, or PIPE, securities purchase agreement, or the PIPE Purchase Agreement, for the April 2024 Private Placement. Pursuant to the PIPE Purchase Agreement, we agreed to issue and sell to the PIPE investors an aggregate of (i) 8,235,000 shares of our common stock at a purchase price of $8.50 per share, and (ii) Pre-Funded Warrants to purchase up to an aggregate of 7,060,000 shares of our common stock at a purchase price of $8.499 per Pre-Funded Warrant, which represents the per share purchase price of our common stock less the $0.001 per share exercise price for each Pre-Funded Warrant. The Pre-Funded Warrants are exercisable at any time after the date of issuance and do not expire. The April 2024 Private Placement closed on April 11, 2024, for aggregate net proceeds of $123.8 million, after deducting fees and expenses of $6.2 million.

We have incurred recurring operating losses since inception. Our net losses for the nine months ended September 30, 2025 and 2024 were $58.9 million and $57.7 million, respectively. As of September 30, 2025, we had an accumulated deficit of $255.9 million. These losses have resulted primarily from costs incurred in connection with research and development activities and general and administrative costs associated with our operations. We expect to continue to incur significant and increasing expenses and operating losses for the foreseeable future, particularly if and as we:

continue to conduct or initiate new preclinical studies and clinical trials for our clinical stage assets, ACR-368 and ACR-2316;
continue to discover and develop additional drug candidates and drug-tailored OncoSignature tests;
acquire or in-license other drug candidates and technologies;
maintain, expand, and protect our intellectual property portfolio;
hire additional clinical and scientific personnel;
further develop and refine the manufacturing processes for ACR-368, the ACR-368 OncoSignature, ACR-2316, or any future drug candidates;
seek regulatory approvals and pursue commercialization for any drug candidates that successfully complete clinical trials; and
add operational, financial, and management information systems and personnel, including personnel to support our drug development and planned future commercialization efforts, as well as to support our obligations as a public reporting company.

We are incurring and expect to continue to incur significant costs associated with operating as a public company. Furthermore, we will not generate revenue from drug sales until we successfully complete clinical development and obtain regulatory approval for a drug candidate. In addition, if we obtain regulatory approval for a drug candidate and do not enter into a third-party commercialization partnership, we expect to incur significant expenses related to developing our commercialization capability to support drug sales, marketing, manufacturing and distribution activities. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our planned clinical studies, milestones achieved, and our expenditures on other research and development activities.

As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time that we can generate significant revenue from drug sales, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. If we are unable to raise capital as needed, this could have a negative impact on our financial condition and ability to pursue our business strategies including requiring us to delay, reduce or eliminate drug development or future commercialization efforts. The amount and timing of our future funding requirements will depend on many factors including the successful advancement of ACR-368, the ACR-368 OncoSignature, ACR-2316, or any future drug candidates. Our ability to raise additional funds may also be adversely impacted by potential worsening global economic conditions, and disruptions to, and volatility in the credit and financial markets in the United States and worldwide, such as those resulting from conflicts in the Middle East and the war in Ukraine and the uncertainties related to

international trade policies and tariffs. There can be no assurances that the current operating plan will be achieved or that additional funding will be available on terms acceptable to us, or at all.

As of September 30, 2025, we had cash, cash equivalents and investments of $134.4 million. We believe that our existing cash, cash equivalents and investments as of September 30, 2025, will enable us to fund our operating expenses and capital expenditure requirements into the second quarter of 2027. 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 the section titled "-Liquidity and Capital Resources."

Companion Diagnostic Agreement

In June 2022, we entered into a companion diagnostic agreement, or the Akoya Agreement, with Akoya Biosciences, Inc., or Akoya, pursuant to which we agreed to co-develop, validate, and commercialize our proprietary ACR-368 OncoSignature test, the companion diagnostic that will be used to identify patients with endometrial cancer most likely to respond to ACR-368.

Pursuant to the agreement, as subsequently amended, we paid Akoya, now a wholly owned subsidiary of Quanterix Corporation, a one-time, non-refundable, non-creditable upfront payment in the amount of $0.6 million. We are obligated to pay Akoya up to an aggregate of $20.3 million upon the achievement of specified development and pre-commercialization milestones. As of November 13, 2025, development and pre-commercialization milestones totaling $18.2 million have been achieved by Akoya under the agreement. Other than certain specified pass-through costs, each party is responsible for its own costs associated with the development of the companion diagnostic. Akoya will procure and manufacture necessary supplies to perform the ACR-368 OncoSignature test to support our clinical development and commercial requirements, in accordance with a supply agreement to be mutually agreed upon by the parties. We may terminate the agreement at our convenience, subject to the payment of a termination fee in the amount of $1.0 million.

Components of Results of Operations

Revenue

To date, we have not generated any revenue, and we do not expect to generate any revenue in the foreseeable future from drug sales. We may in the future generate revenue from payments received under collaboration agreements, which could potentially include (but not be limited to) payments of upfront fees, license fees, milestone-based payments and reimbursements for research and development efforts.

Operating Expenses

Research and Development

The majority of our expenses have been research and development expenses, which consist primarily of costs incurred in connection with our research and development activities, including our drug discovery efforts and the development of ACR-368 and ACR-2316, and the ACR-368 OncoSignature. We expense research and development costs as incurred, which include:

direct cost for conducting internal research and development to generate preclinical validation data for ACR-368 including the ACR-368 OncoSignature, for ACR-2316, and for our internal preclinical drug discovery programs;
the cost to obtain and maintain licenses to intellectual property, such as those with Lilly and related future payments should certain milestones be achieved;
external research and development expenses incurred under agreements with contract research organizations, or CROs, as well as investigative sites and consultants that conduct our clinical trials and other scientific development services;
costs related to manufacturing material for our clinical trials, including fees paid to contract manufacturing organizations, or CMOs;
manufacturing scale-up expenses and the cost of acquiring and manufacturing clinical trial materials;
employee-related expenses, including salaries, bonuses, benefits, stock-based compensation, and other related costs for those employees involved in research and development efforts;
costs of outside consultants, including their fees, stock-based compensation, and related travel expenses;
expenses to acquire technologies to be used in research and development;
upfront and maintenance fees incurred under license, acquisition, and other third-party agreements;
costs related to regulatory activities, including filing fees paid to regulatory agencies and compliance with regulatory requirements; and
facilities, depreciation, and other expenses, which include direct and allocated expenses for rent, maintenance of facilities, and equipment and software.

Research and development costs are expensed as incurred. We recognize external development costs as related goods are delivered or services are performed. Significant judgments and estimates are made in determining the accrued expense balances at the end of any reporting period.

We record direct costs for our early stage, discovery, and development drug candidates at the program level. Our indirect research and development costs are primarily personnel-related costs, facilities, and other costs. Employees and infrastructure are not directly tied to any one program and are deployed across our programs. As such, we do not track these costs on a specific program basis.

Our external research and development expenses consist primarily of fees paid to CROs, CMOs, research laboratories, and outside consultants in connection with our process development, manufacturing, and clinical development activities. Our direct external research and development expenses also include fees incurred under license and intellectual property purchase agreements. We track these external research and development costs on a program-by-program basis once we have identified a drug candidate.

The successful development of our ACR-368 and ACR-368 OncoSignature test, ACR-2316, or any other future drug candidates, is highly uncertain. We plan to substantially increase our research and development expenses for the foreseeable future as we continue the development and manufacturing of ACR-368 and ACR-2316 and conduct discovery and research activities for our preclinical programs.

We cannot determine with certainty the timing of initiation, the duration, or the completion costs of current or future clinical trials of our drug candidates due to the inherently unpredictable nature of preclinical and clinical development. Clinical development timelines, the probability of success and development costs can differ materially from expectations. We anticipate that we will make determinations as to which drug candidates to pursue and how much funding to direct to each drug candidate on an ongoing basis in response to the results of ongoing and future clinical trials, regulatory developments and our ongoing assessments as to each drug candidate's commercial potential. We will need to raise substantial additional capital in the future. Our clinical development costs are expected to increase significantly with our ongoing and planned clinical trials. We anticipate that our expenses will increase substantially, particularly due to the numerous risks and uncertainties associated with developing drug candidates, including the uncertainty of:

the scope, rate of progress and expenses of our ongoing research activities and clinical trials and other research and development activities;
confirming the appropriate safety profile established in past clinical trials;
successful enrollment in and completion of clinical trials;
whether our drug candidates show efficacy with an increased ORR through patient responder identification in our clinical trials;
receipt of marketing approvals from applicable regulatory authorities;
establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;
obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our drug candidates;
the extent to which we establish additional collaboration or license agreements;
commercializing drug candidates, if and when approved, whether alone or in collaboration with others; and
continued acceptable safety profile of the products following any regulatory approval.

Any changes in the outcome of any of these variables with respect to the development of our drug candidates in clinical development could mean a significant change in the costs and timing associated with the development of these drug candidates. We may never succeed in achieving regulatory approval for any of our drug candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of some drug candidates or focus on others. For example, if the FDA, European Medicines Agency 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 drug candidate.

General and Administrative

General and administrative expenses consist primarily of employee-related costs, including salaries, bonuses, benefits, and stock-based compensation expenses for personnel in executive, finance, accounting, human resources and other administrative functions. Other significant general and administrative expenses include legal fees relating to patent, intellectual property and corporate matters, fees paid for accounting, audit, consulting and other professional services, and expenses for rent, insurance and other operating costs.

We anticipate that our general and administrative expenses will continue to increase in the future as we increase our headcount and services to support our continued research activities and development of our drug candidates. We also anticipate that we will continue to incur significant accounting, audit, legal, regulatory, compliance and director and officer insurance costs, as well as investor and public relations expenses associated with operating as a public company.

Research and development expenses were $13.6 million for the three months ended September 30, 2025, compared to $18.9 million for the three months ended September 30, 2024. The decrease of $5.2 million was primarily due to:

a $7.1 million net decrease in costs driven by fewer scheduled and incurred milestones in the current period, as well as the prioritization of endometrial cancer over other tumor types in the ACR-368 clinical trial;
a $0.9 million net increase in costs related to ACR-2316, our novel, internally-discovered clinical stage asset. We initiated a clinical trial and related activities in the third quarter of 2024, which has continued to progress through 2025; and
a $0.7 million increase in personnel-related costs, including $0.2 million of changes to stock-based compensation expense, primarily due to higher annual salaries over time.

General and Administrative Expenses

General and administrative expenses of $6.0 million for the three months ended September 30, 2025 were consistent with general and administrative expenses for the three months ended September 30, 2024.

Total Other Income, Net

Total other income, net was $1.5 million for the three months ended September 30, 2025, compared to total other income, net of $2.7 million for the three months ended September 30, 2024. The change of $1.2 million is primarily attributable to a decrease in interest income and accretion earned on our investments.

Research and development expenses were $45.2 million for the nine months ended September 30, 2025, compared to $45.4 million for the nine months ended September 30, 2024. The decrease of $0.1 million was primarily due to:

a $6.5 million net decrease in costs driven by fewer scheduled and incurred milestones in the current period, as well as the prioritization of endometrial cancer over other tumor types in the ACR-368 clinical trial;
a $3.8 million net increase in costs related to ACR-2316, our novel, internally-discovered clinical stage asset. We initiated a clinical trial and related activities in the third quarter of 2024, which has continued to progress through 2025;
a $1.8 million net decrease in costs related to preclinical drug discovery activities progression, which prior to ACR-2316 initiation in the third quarter of 2024, had included ACR-2316 and in 2025 is significantly comprised of investment in our preclinical cell cycle program with an undisclosed target;
a $3.3 million increase in personnel-related costs, including $0.7 million of changes to stock-based compensation expense, primarily due to an increase in research and development headcount and higher annual salaries over time; and
a $1.0 million increase in facilities, supplies and other expenses, primarily driven by an increase in headcount and related research activities.

General and Administrative Expenses

General and administrative expenses of $18.8 million for the nine months ended September 30, 2025 were consistent with general and administrative expenses for the nine months ended September 30, 2024.

Total Other Income, Net

Total other income, net was $5.1 million for the nine months ended September 30, 2025, compared to total other income, net of $6.5 million for the nine months ended September 30, 2024. The change of $1.4 million is primarily attributable to a decrease in interest income and accretion earned on our investments.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception, we have not recognized any revenue and have incurred significant losses in each period and on an aggregate basis. We have not yet commercialized any drug candidates, and we do not expect to generate revenue from sales of any drug candidates or from other sources for several years, if at all. As of September 30, 2025, we had $134.4 million in cash, cash equivalents and investments, and we had an accumulated deficit of $255.9 million. We have funded our operations primarily with proceeds from the sales of shares of our convertible preferred stock, the issuance of convertible notes, our IPO and concurrent private placement, and our April 2024 Private Placement. We believe that our existing cash, cash equivalents and investments of $134.4 million as of September 30, 2025, will enable us to fund our operating expenses and capital expenditure requirements into the second quarter of 2027.

Net Cash Used in Operating Activities

Net cash used in operating activities was $48.4 million for the nine months ended September 30, 2025, compared to net cash used in operating activities of $48.3 million for the nine months ended September 30, 2024. The increase in net cash used in operating activities of $0.1 million was primarily driven by an increase in net loss of $1.2 million, partially offset by a $1.0 million increase in non-cash stock-based compensation expense.

Net Cash Provided by (Used in) Investing Activities

Net cash provided by investing activities was $44.6 million for the nine months ended September 30, 2025, resulting from $114.5 million in proceeds from maturities of investments, offset by purchases of investments of $68.5 million and purchases of property and equipment of $1.5 million.

Net cash used in investing activities was $66.2 million for the nine months ended September 30, 2024, resulting from purchases of investments of $168.2 million and purchases of property and equipment of $1.9 million, offset by $103.9 million in proceeds from maturities of investments.

Net Cash (Used In) Provided by Financing Activities

Net cash used in financing activities was $0.6 million for the nine months ended September 30, 2025, primarily resulting from $0.6 million of payments for tax withholdings related to the vesting of restricted stock units.

Net cash provided by financing activities was $121.7 million for the nine months ended September 30, 2024, resulting from $130.0 million in proceeds from the April 2024 Private Placement and $0.1 million in proceeds from the exercise of stock options, offset by $1.9 million of payments for tax withholdings related to the vesting of restricted stock units and $6.5 million of payments of offering costs.

Funding Requirements

As of September 30, 2025, our cash, cash equivalents and investments were $134.4 million. We believe that our existing cash, cash equivalents and investments as of September 30, 2025, will enable us to fund our operating expenses and capital expenditure requirements into the second quarter of 2027. We have based this estimate on assumptions that may prove to be wrong, and we could expend our capital resources sooner than we expect.

We expect to incur significant expenses and operating losses for the foreseeable future as we advance our drug candidates through clinical development, seek regulatory approval and pursue commercialization of any approved drug candidates. We expect that our research and development and general and administrative costs will increase in connection with our planned research and clinical activities and operating as a public company. If we receive regulatory approval for any of our drug candidates, we expect to incur significant commercialization expenses related to drug manufacturing, sales, marketing and distribution, depending on where we choose to commercialize. We may also require additional capital to pursue in-licenses or acquisitions of other drug candidates.

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

the scope, timing, progress, results and costs of preclinical and clinical development activities;
the costs, timing and outcome of regulatory review of drug candidates;
the costs of future activities, including drug sales, medical affairs, marketing, manufacturing and distribution, for any drug for which we receive marketing approval;
the costs of establishing and maintaining arrangements with third party manufacturers for the commercial supply of products that receive marketing approval, if any;
the revenue, if any, received from commercial sale of our products, should any drug candidates receive marketing approval;
the cash requirements of any future in-licenses, acquisitions or discovery of drug candidates;
the cost and timing of attracting, hiring and retaining skilled personnel to support our operations and continued growth;
the cost of implementing operational, financial and management systems;
the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;
our ability to establish and maintain collaborations, strategic partnerships or marketing, distribution, licensing or other strategic arrangements with third parties on favorable terms, if at all; and
the timing, receipt and amount of sales of, or milestone payments related to or royalties on, current or future drug candidates, if any.

A change in the outcome of any of these or other variables with respect to the development of ACR-368, the ACR-368 OncoSignature, ACR-2316, or any drug or development candidate we may develop in the future could significantly change the costs and timing associated with our development plans. Further, our operating plans may change in the future, and we may need additional funds to meet operational needs and capital requirements associated with such operating plans.

Until such time, if ever, as we can generate substantial drug revenues to support our expenses, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations and other similar arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be or could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing and 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 capital expenditures or declaring dividends. If we raise funds through collaborations, or other similar arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs, drug candidates or grant licenses on terms that may not be favorable to us and/or may reduce the value of our common stock. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our drug development or future commercialization efforts or grant rights to develop and market our drug candidates even if we would otherwise prefer to develop and market such drug candidates ourselves.

Contractual Obligations

Except as discussed in Note 12 to our unaudited condensed consolidated financial statements appearing elsewhere in this Quarterly Report, during the nine months ended September 30, 2025, there were no material changes to our contractual obligations and commitments from those described in our Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the SEC on March 27, 2025.

Critical Accounting Policies and Significant Judgments and Estimates

Our financial statements are prepared in accordance with generally accepted accounting principles in the United States. The preparation of our financial statements and related disclosures requires us to make estimates, assumptions and judgments that affect the reported amount of assets, liabilities, revenue, costs and expenses, and related disclosures. 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 Significant Judgments and Estimates" in our Annual Report on Form 10-K. If actual results or events differ materially from the estimates, judgments and assumptions used by us in applying these policies, our reported financial condition and results of operations could be materially affected. There have been no significant changes to our critical accounting policies from those described in our Annual Report on Form 10-K.

Recent Accounting Pronouncements

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

Emerging Growth Company and Smaller Reporting Company Status

The JOBS Act provides that, among other things, an "emerging growth company" can take advantage of an extended transition period for complying with new or revised accounting standards. This provision allows an emerging growth company to delay the adoption of some accounting standards until those standards would otherwise apply to private companies. As an emerging growth company, we have elected not to "opt out" of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for private companies on a case-by-case basis 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. As a result, our consolidated financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates. We may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for private companies. We intend to rely on certain of the other exemptions and reduced reporting requirements provided by the JOBS Act. As an emerging growth company, we are not required to, among other things, (i) provide an auditor's attestation report on our system of internal controls over financial reporting pursuant to Section 404(b), and (ii) comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding a supplement to the auditor's report providing additional information about the audit and the financial statements (auditor discussion and analysis).

We will remain an emerging growth company until the earlier to occur of (1) the last day of our fiscal year (a) following the fifth anniversary of the closing of our IPO, (b) in which we have total annual gross revenues of at least $1.235 billion or (c) in which we are deemed to be a "large accelerated filer" under the rules of the SEC, which means the market value of our common shares that is held by non-affiliates exceeds $700 million as of the last day of our second quarter, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

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 is 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 on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.
