Overview
We are a clinical-stage biotechnology company committed to applying our leading expertise in the field of oncolytic immunotherapy to transform the lives of cancer patients through our novel oncolytic immunotherapies. Our proprietary oncolytic immunotherapy product candidates are designed and intended to maximally activate the immune system against cancer.
Oncolytic immunotherapy is an emerging drug class, which we intend to establish as the second cornerstone of immune-based cancer treatments, alongside checkpoint blockade. Oncolytic immunotherapy exploits the ability of certain viruses to selectively replicate in and directly kill tumors, as well as induce a potent, patient-specific, anti-tumor immune response. Our product candidates incorporate multiple mechanisms into a practical "off-the-shelf" approach that is intended to maximize the immune response against a patient's cancer and to offer significant advantages over other approaches of inducing anti-tumor immunity. We believe that the bundling of multiple approaches for the treatment of cancer into single therapies will increase clinical efficacy and simplify the development path of our product candidates, while also improving patient outcomes.
Financial
Since our inception, we have devoted substantially all of our resources to developing our proprietary RPx platform, building our intellectual property portfolio, conducting research and development of our product candidates, business planning, raising capital and providing selling, general and administrative support for our operations. To date, we have incurred significant operating losses and we have financed our operations primarily with proceeds from the sale of equity securities and to a lesser extent, proceeds from borrowing under secured loan facilities. Our ability to generate product revenue sufficient to achieve profitability will depend on the successful development and eventual commercialization of one or more of our product candidates. We do not have any products approved for sale and have not generated any revenue from product sales.
Since our initial public offering, or IPO, on July 20, 2018, we have raised an aggregate of approximately $1,132.9 million in net proceeds to fund our operations, of which $101.2 million was from our IPO, $862.0 million was from five separate follow-on offerings, or the Public Offerings, that we closed in November 2019, June 2020, October 2020, December 2022, and November 2024, respectively, $96.7 million was from our private placement transaction in June 2024, and $73.0 million was from at-the-market offerings.
Our net losses were $313.9 million and $247.3 million for the years ended March 31, 2026 and 2025, respectively. As of March 31, 2026, we had an accumulated deficit of $1,262.5 million. These losses have resulted primarily from costs incurred in connection with research and development activities and selling, general and administrative costs associated with our operations. We expect to continue to incur significant expenses and increasing operating losses for at least the next several years.
We anticipate that our expenses and capital requirements will fluctuate from period to period depending upon the Company's development programs and priorities. We expect to continue to incur costs in connection with our ongoing development activities, including further advancement of any preclinical activities and clinical trials of our product candidates across our platform, and if and as we:
•continue to conduct our current and future clinical trials;
•further preclinical development of our platform;
•operate our in-house manufacturing facility;
•seek to identify and develop additional product candidates;
•seek marketing approvals for any of our product candidates that successfully complete clinical trials, if any;
•establish a sales, marketing and distribution infrastructure to commercialize any products for which we may obtain marketing approval;
•maintain, expand and protect our intellectual property portfolio;
•hire, train and retain additional clinical, quality control, scientific and selling, general and administration personnel;
•acquire or in-license other drugs, technologies or intellectual property rights; and
TABLE OF CONTENTS
•add operational, financial and management information systems and personnel, including personnel to support our research and development programs, any future commercialization efforts and operations as a public company.
Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.
As of March 31, 2026, we had cash and cash equivalents and short-term investments of $268.9 million. Based on our current operating plan, we believe that our existing cash and cash equivalents and short-term investments will enable us to fund our operating expenses and capital expenditure requirements into the first calendar quarter of 2027, which includes scale up for the potential commercialization of RP1 in skin cancers and for working capital and general corporate purposes and excludes any potential revenue. We have based these estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect.
See "Results of Operations - Liquidity and capital resources" and "Risk factors - Risks related to our financial position and need for additional capital."
Components of our results of operations
Revenue
To date, we have not generated any revenue from product sales as we do not have any approved products and we can not be certain we will generate any revenue from the sale of products in the future. If our development efforts for RP1 or any other product candidates that we may develop in the future are successful and result in regulatory approval, or if we enter into collaboration or license agreements with third parties, we may generate revenue in the future from a combination of product sales or payments from those collaborations or license agreements.
Operating expenses
Our expenses since inception have consisted solely of research and development costs and general and administrative costs.
Research and development expenses
Research and development expenses consist primarily of costs incurred for our research activities, including our discovery efforts and the development of our product candidates, and include:
•expenses incurred under agreements with third parties, including clinical research organizations, or CROs, that conduct research, preclinical activities and clinical trials on our behalf as well as contract manufacturing organizations, or CMOs that manufacture our product candidates for use in our preclinical and clinical trials;
•salaries, benefits and other related costs, including stock-based compensation expense, for personnel engaged in research and development functions;
•costs of outside consultants engaged in research and development functions, including their fees, stock-based compensation and related travel expenses;
•the costs of laboratory supplies and acquiring, developing and manufacturing preclinical study and clinical trial materials;
•costs related to compliance with regulatory requirements in connection with the development of our product candidates; and
•facility-related expenses, which include direct depreciation costs and allocated expenses for rent and maintenance of facilities and other operating costs.
We expense research and development costs as incurred. We recognize external development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our service providers. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in our consolidated financial statements as prepaid or accrued research and development expenses.
Direct research and development costs, consisting of costs, such as fees paid to consultants, contractors, CMOs and CROs in connection with our preclinical and clinical development activities, are tracked by study. Additional costs, consisting
TABLE OF CONTENTS
primarily of our initial manufacturing costs, including materials, supplies, depreciation and facility costs, are allocated at a program level, based upon manufacturing runs, as the drug product can be utilized across multiple studies for any particular program. Additional costs to label, package and distribute the drug product is then directly allocated to the specific studies when incurred, as that drug product has then been assigned to a particular study. In the event our additional future or ongoing study costs become meaningful to investors, we will present those costs by study.
We do not allocate personnel costs, costs associated with our discovery efforts, laboratory supplies or other indirect costs, to specific product development programs because these costs are deployed across multiple product development programs and, as such, are not separately classified.
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 that our research and development expenses will continue to increase for the foreseeable future as we continue enrollment in, and the initiation of, additional clinical trials, as well as the continued discovery and development of additional product candidates. However, if we determine that the continued development of RP1 is not viable, our outlook and plans may be uncertain and the impact on our research and development expenses will also be uncertain. At this time our ability to fund and successfully develop, and commercialize, if approved, our product candidates is highly uncertain. This is due to the numerous risks and uncertainties associated with product development and commercialization, including the following:
•the extent to which we are able to reach a mutually agreeable path forward with the FDA with respect to the scope, design, implementation and timing of an approval for RP1 (vusolimogene oderparepvec) in combination with nivolumab for the treatment of adult patients with advanced melanoma who have previously received an anti-PD-1 containing regimen the scope, rate of progress, expense and results of our ongoing clinical trials, as well as future clinical trials or other product candidates and other research and development activities that we may conduct;
•the number and scope of preclinical and clinical programs we decide to pursue;
•our ability to maintain our current research and development programs and to establish new ones;
•uncertainties in clinical trial design;
•the rate of enrollment in clinical trials;
•the successful completion of clinical trials with safety, tolerability, and efficacy profiles that are satisfactory to the FDA or any comparable foreign regulatory authority;
•the receipt of regulatory approvals from applicable regulatory authorities;
•our success in operating our manufacturing facility, or securing manufacturing supply through relationships with third parties;
•our ability to obtain and maintain patents, trade secret protection, and regulatory exclusivity, both in the United States and internationally;
•our ability to maintain, expand and protect our rights in our intellectual property portfolio;
•the commercialization of our product candidates, if and when approved and the timing of such approval;
•the acceptance of our product candidates, if approved, by patients, the medical community, and third-party payors;
•our ability to successfully develop our product candidates for use in combination with third-party products or product candidates;
•negative developments in the field of immuno-oncology;
•competition with other products; and
•significant and changing government regulation and regulatory guidance and the views and implementation of such regulation and guidance from the leadership of the applicable regulatory agency.
A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant trial delays due to patient enrollment or other reasons, we could be required to expend significant additional financial resources and time on the completion of clinical development. We may never succeed in obtaining regulatory approval for any of our product candidates.
TABLE OF CONTENTS
Selling, general and administrative expenses
Selling, general and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in our executive, finance, corporate, commercial, and business development and administrative functions. Selling, general and administrative expenses also include professional fees for legal, patent, accounting, auditing, tax and consulting services, pre-commercial planning, travel expenses, and facility-related expenses, which include direct depreciation costs and allocated expenses for rent and maintenance of facilities and other operating costs.
If the FDA provides an accelerated approval of our BLA for RP1 plus nivolumab for the treatment of advanced melanoma, we expect that our selling, general and administrative expenses will continue to increase in the future as we increase our selling, general and administrative headcount to support our continued operations and pre-launch activities to prepare for potential commercialization of our product candidates. We also expect to continue to incur increased expenses, including accounting, audit, legal, regulatory and tax-related services associated with maintaining compliance with exchange listing and SEC requirements; director and officer insurance costs; and investor and public relations costs. If we determine that the continued development of RP1 is not viable, we expect that our selling, general and administrative expenses will decrease but to what extent we are uncertain.
Other income (expense), net
Research and development incentives
Research and development incentives consists of reimbursements of research and development expenditures. We participate, through our subsidiary in the United Kingdom, in the research and development program provided by the United Kingdom tax relief program, such that a percentage of up to 16.2% of our qualifying research and development expenditures are reimbursed by the United Kingdom government, and such incentives are reflected as other income.
Investment income
Investment income consists of income earned on our cash and cash equivalents and short-term investments.
Interest expense on finance lease liability
Interest expense on finance lease liability consists of amortization of finance charges under our finance lease.
Interest expense on debt obligations
Interest expense on debt obligations consists of the amortization of debt discount and cash paid for interest under the Hercules Loan Agreement.
Other (expense) income, net
Other (expense) income, net consists primarily of realized and unrealized foreign currency transaction gains and losses.
Income taxes
During the years ended March 31, 2026 and 2025, the Company recorded an income tax benefit of $0.6 million and a provision of $0.5 million, respectively.

The total increase of $31.7 million in research and development expenses was driven by an increase of $24.5 million in our direct research and development costs, as well as an increase of $7.2 million in unallocated expenses. The increase of approximately $24.5 million in our direct research and development costs was driven by an increase of $13.9 million in spending on RP2 study costs during the year, primarily related to the REVEAL study, as the Company continued to ramp up enrollment and expanded this trial outside of the United States. In addition, RP1 costs increased by $12.9 million as a result of costs related to the IGNYTE-3 confirmatory study as well as an increase of $7.7 million in other RP1 study costs, specifically operating and lab supplies, and facility costs. These increases were partially offset by decreases in the IGNYTE and CERPASS
TABLE OF CONTENTS
studies as a result of the completion of enrollment in the IGNYTE advanced melanoma cohort and declining enrollment and the wind down of the CERPASS study.
The increase in unallocated expenses includes an increase of $9.8 million in personnel-related costs, which is primarily related to an increase of $11.6 million in payroll and fringe benefits which largely reflected the increase in personnel in our research and development functions year over year as we expanded the development plan in multiple indications. The decrease in other costs is driven by a year over year decrease in consulting costs.
Selling, general and administrative expenses
Selling, general and administrative expenses were $98.7 million for the year ended March 31, 2026, compared to $72.2 million for the year ended March 31, 2025. The increase of $26.6 million in sales, general and administrative costs is driven primarily by an increase of $20.3 million in personnel related costs, comprised of an increase of $21.4 million in payroll and fringe benefits slightly offset by a stock-based compensation decrease of $1.1 million. The increase in personnel related costs was driven by the continued hiring of additional personnel within our selling, general and administrative functions, specifically focusing on planning for a potential commercial launch. Personnel related costs for the year ended March 31, 2026 and 2025 included stock-based compensation expense of $15.5 million and $16.6 million, respectively.
Total other income (expense), net
Other income for the year ended March 31, 2026 was $5.4 million compared to $14.8 million for the year ended March 31, 2025. The net change of $9.4 million is primarily attributable to a decrease of $7.5 million in investment income in the current year as compared to the prior year as a result of the cash and investment balance being lower throughout the year as compared to the prior year due to normal cash burn, as well as an increase in interest expense on debt obligations in the amount of $1.0 million as a result of a higher debt balance during the current year vs. the prior year.
Income tax provision
The income tax benefit for the year ended March 31, 2026 was $0.6 million compared to an income tax provision of $0.5 million for the year ended March 31, 2025.
Liquidity and capital resources
Since our inception, we have not generated any revenue from product sales and have incurred significant operating losses and negative cash flows from our operations. Until we are able to generate sufficient revenue from RP1 and our other product candidates that we develop, if at all, we anticipate that we will continue to incur significant operating losses and negative cash flows from our operations.
Based on its current operating plan, the Company expects to continue to generate operating losses for the foreseeable future and that its existing cash, cash equivalents and short-term investments will be sufficient to fund its operating expenses and capital expenditure requirements only into the first calendar quarter of 2027, which is less than one year from the date these consolidated financial statements are issued. The Company does not have any committed source of additional funding and will be required to obtain additional financing to fund its operations beyond that date. These conditions raise substantial doubt about the Company's ability to continue as a going concern.
The Company is collaborating with the FDA regarding a path forward for RP1 and, if the BLA is approved, the Company will determine the best source of capital, which may be raising additional capital through public or private equity offerings (including under our at-the-market facilities), although there can be no guarantee that the Company will be able to raise such capital on acceptable terms, or at all. If the BLA is not approved, the Company will likely need to (i) execute a considerable restructuring and workforce reduction to reduce our cash burn, (ii) reconsider our product development efforts and strategies and (iii) pursue collaborations, strategic alliances, licensing arrangements, business combination, merger or acquisition, or other strategic business development activities to continue operations. In either scenario, our plans are subject to risks and uncertainties, including factors outside our control. Accordingly, we have not been able to conclude that these plans are probable of being effectively implemented and, as such, they do not alleviate the substantial doubt about our ability to continue as a going concern.
Sources of liquidity
To date, we have financed our operations primarily with proceeds from the sale of equity securities and, to a lesser extent, proceeds from borrowing under a secured loan facility. Through March 31, 2026, we had received net proceeds of $1,132.9
TABLE OF CONTENTS
million through the sale of shares of common stock and pre-funded warrants exercisable for common stock in public offerings, a private placement transaction, and at-the-market offerings, as well as our incurrence of debt under the Hercules Loan Agreement. As of March 31, 2026, we had cash and cash equivalents and short-term investments of $268.9 million.

Funding requirements
TABLE OF CONTENTS
Our plan of operation is to continue implementing our business strategy, continue research and development of RP1 and our other product candidates and continue to expand our research pipeline and our internal research and development capabilities. We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we advance the preclinical activities and clinical trials of our product candidates, and potential commercialization of RP1 and if and as we:
•conduct our current and future clinical trials with RP1, RP2 and RP3;
•further preclinical development of our RPx platform;
•operate, qualify and maintain our in-house manufacturing facility and qualify and maintain our product candidates made therein for use in our clinical trials;
•seek to identify and develop additional product candidates;
•seek marketing approvals for any of our product candidates that successfully complete clinical trials, if any;
•establish a sales, marketing and distribution infrastructure to commercialize any products for which we may obtain marketing approval;
•until our planned manufacturing facility is fully validated, continued limited manufacturing by third parties for clinical development;
•maintain, expand and protect our intellectual property portfolio;
•acquire or in-license other drugs, technologies or third-party intellectual property; and
•add operational, financial and management information systems and personnel, including personnel to support our research and development programs, any future commercialization efforts and operations as a public company.
As of March 31, 2026, we had cash and cash equivalents and short-term investments of $268.9 million and $83.3 million in long term debt. Based on our current operating plan, we believe that our existing cash, cash equivalents and short-term investments as of March 31, 2026, will enable us to fund operations into the first calendar quarter of 2027 which includes scale up for the potential commercialization of RP1 in skin cancers and for working capital and general corporate purposes and excludes any potential revenue. We have based these estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect.
Because of the numerous risks and uncertainties associated with the development of RP1 and other product candidates and programs, and because the extent to which we may enter into collaborations with third parties for development of our product candidates is unknown, we are unable to estimate the timing and amounts of increased capital outlays and operating expenses associated with completing the research and development and potential commercialization of our product candidates. Our future capital requirements will depend on many factors, including those described in this section and above under "- Operating expenses - Research and development expenses."
Developing novel biopharmaceutical products, including conducting preclinical studies and clinical trials, is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval for any product candidates or generate revenue from the sale of any products for which we may obtain marketing approval. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of therapies that we do not expect to be commercially available for many years, if ever. Accordingly, we will need to obtain substantial additional funds to achieve our business objectives.
Adequate additional funds may not be available to us on acceptable terms, or at all. We do not currently have any committed external source of funds. To the extent that we raise additional capital through the sale of our equity or convertible debt securities, our shareholders' interest may be diluted, and the terms of these securities may include liquidation or other preferences and anti-dilution protections that could adversely affect the rights of our common stockholder. Additional debt or preferred equity financing, if available, may involve agreements that include restrictive covenants that may limit our ability to take specific actions, such as incurring debt, adversely impact our ability to conduct our business, and may require the issuance of warrants, which could potentially dilute your ownership interest.
If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technology, 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 collaborations, strategic alliances or licensing arrangements with third parties when needed, we may be required

to delay, limit, reduce and/or terminate our product development programs or any future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.
Contractual obligations and commitments
We have entered into arrangements that contractually obligate us to make payments that will affect our liquidity and cash flows in future periods. Our contractual obligations include those related to our operating and finance leases, long-term debt, as well as costs associated with contracts entered into in the normal course of business with CROs, CMOs and other third parties for clinical trials and preclinical research studies and testing.
Lease Commitments
As of March 31, 2026, the aggregate amount of future lease payments is approximately $45.1 million, with $4.0 million due within one year. For additional information on our leases and timing of future payments, see Note 13 Commitments and contingencies, of the "Notes to Consolidated Financial Statements" contained in Part II, Item 8 of this Annual Report on Form 10-K.
Loan Agreement
Our commitments due for our term loan under our arrangement with Hercules include principal payments of $80.0 million as of March 31, 2026. Borrowings under the term loan agreement are repayable in monthly interest-only payments through September 2027, and the agreement has a maturity date of October 2027. A balloon payment, inclusive of accrued interest and principal, are due on the maturity date of October 1, 2027. Our remaining commitments, based on our current draws, are due on October 2027, and include principal and interest payments of $84.2 million, and an additional fee upon maturity of the loan of $4.0 million. See Note 7, Long term debt, of the "Notes to Consolidated Financial Statements" contained in Part II, Item 8 of this Annual Report on Form 10-K for further discussion of the Hercules term loan.
Other Obligations
Manufacturing and research commitments include agreements that are enforceable and legally binding on us and that specify all significant terms, including fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. As of March 31, 2026, the aggregate amount of non-cancelable purchase obligations related to such manufacturing commitments are approximately $0.8 million and all of this balance is due within one year.
Collaborations
BMS
In February 2018, we entered into a Clinical Trial Collaboration and Supply Agreement with Bristol-Myers Squibb Company, or BMS. Pursuant to the agreement, BMS is providing to us, at no cost, nivolumab, its anti-PD-1 therapy, for use in combination with RP1 in our ongoing Phase 1/2 clinical trial. Under the agreement, we will sponsor, fund and conduct the clinical trial in accordance with an agreed-upon protocol. BMS granted us a non-exclusive, non-transferrable, royalty-free license (with a right to sublicense) under its intellectual property to use nivolumab in the clinical trial and has agreed to supply nivolumab, at no cost to us, for use in the clinical trial. Both parties will own the study data produced in the clinical trial, other than study data related solely to nivolumab, which will belong solely to BMS, or study data related solely to RP1, which will belong solely to us. In January 2020, this agreement was expanded to cover an additional cohort of 125 patients with anti-PD-1 failed melanoma.
Unless earlier terminated, the agreement will remain in effect until (i) the completion of the clinical trial, (ii) all related clinical trial data have been delivered to both parties and (iii) the completion of any statistical analyses and bioanalyses contemplated by the clinical trial protocol or any analysis otherwise agreed upon by the parties. The agreement may be terminated by either party (x) in the event of an uncured material breach by the other party, (y) in the event the other party is insolvent or in bankruptcy proceedings or (z) for safety reasons. Upon termination, the licenses granted to us to use nivolumab in the clinical trial will terminate. The agreement contains representations, warranties, undertakings and indemnities customary for a transaction of this nature.
In April 2019, we entered into a separate agreement with BMS on terms similar to the terms set forth in the agreement described above, pursuant to which BMS will provide, at no cost to us, nivolumab for use in our Phase 1 clinical trial of RP2 in combination with nivolumab.
Roche
TABLE OF CONTENTS
In December 2022, we entered into a Master Clinical Trial Collaboration and Supply Agreement with Roche in relation to our RP2 and RP3 programs in colorectal cancer, or CRC, and hepatocellular carcinoma, or HCC. Under the agreement, the companies intended to collaborate in 30 patient cohort signal finding studies in third-line, or 3L, CRC and in first- and second-line, or 1L and 2L, respectively, HCC. Following our re-prioritization of our product development portfolio in December 2023, we have agreed with Roche to terminate the CRC collaboration and pursue the 2L cohort in HCC with RP2 only. Roche has continued to supply its currently approved drugs, atezolizumab and bevacizumab for the 2L cohort in HCC but is not sharing costs following our re-prioritization. Under the terms of the initial agreement we retained the responsibility of operating the clinical trials as well as retaining all the rights to the development and commercialization of our product candidates. The agreement may be terminated by either party upon sixty days prior written notice to the other party.
Critical accounting policies and estimates
Our management's discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States. The preparation of our consolidated financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, costs and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.
While our significant accounting policies are described in greater detail in Note 2 to our consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our consolidated financial statements.
Accrued research and development expenses
As part of the process of preparing our 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 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 advanced payments. We make estimates of our accrued expenses as of each balance sheet date in the consolidated financial statements based on facts and circumstances known to us at that time. Examples of estimated accrued research and development expenses include fees paid to:
•CROs in connection with performing research activities and conducting preclinical studies and clinical trials on our behalf;
•CMOs in connection with the production of preclinical and clinical trial materials;
•investigative sites or other service providers in connection with clinical trials;
•vendors in connection with preclinical and clinical development activities; and
•vendors related to product manufacturing and development and distribution of preclinical and clinical supplies.
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 CMOs 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 amount of prepaid expenses 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 and/or timing of receiving invoices for actual 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.
TABLE OF CONTENTS
Stock-based compensation
We issue stock-based awards to employees, directors, consultants and non-employees in the form of stock options, restricted stock units, or RSUs, and performance-based restricted stock units, or PSUs. We measure such stock-based awards in accordance with ASC 718, Compensation - Stock Compensation, which requires all stock-based awards to be recognized in the consolidated statements of operations and comprehensive loss based on their fair value on the date of the grant and the related compensation expense for those awards is recognized over the requisite service period, which is generally the vesting period of the respective award. We have, to date, issued stock-based awards with service-based and performance-based vesting conditions. Expense for stock-based awards with service-based vesting conditions is recorded using the straight-line method and for PSUs with performance-based vesting conditions, the expense is recorded using the graded vesting method. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model, which requires inputs based on certain subjective assumptions, including the expected stock price volatility, the expected term of the option, the risk-free interest rate for a period that approximates the expected term of the option, and our expected dividend yield. See Note 10 of the "Notes to Consolidated Financial Statements" contained in Part II, Item 8 of this Annual Report on Form 10-K for more information. Forfeitures are accounted for as they occur. The fair value of each RSU and PSU is estimated on the date of grant based on the fair value of our common stock on that same date.
We classify stock-based compensation expense in our consolidated statements of operations in the same manner in which the award recipient's payroll costs are classified or in which the award recipient's service payments are classified.
