Company Overview

Capricor Therapeutics, Inc. is a biotechnology company focused on the development and potential commercialization of cell and exosome-based therapeutics for the treatment of Duchenne muscular dystrophy ("DMD"), a rare genetic disorder characterized by progressive muscle degeneration and premature death, as well as other diseases with significant unmet medical need. Since our inception, we have devoted substantial resources to the development of our lead product candidate, Deramiocel, a cell therapy designed to address the cardiac and skeletal muscle complications associated with DMD, as well as to advancing our exosome-based platform technologies, developing manufacturing capabilities and supporting our research and development activities. Our Biologics License Application ("BLA") for Deramiocel for the treatment of DMD is currently under review by the U.S. Food and Drug Administration ("FDA"), with a Prescription Drug User Fee Act ("PDUFA") target action date of August 22, 2026, for potential approval in the United States. We currently have no products approved for commercial sale. Our ability to generate product revenue and achieve profitability will depend on the successful development, regulatory approval and commercialization of Deramiocel and any other product candidates we may develop. If approved and if our litigation against NS Pharma, Inc. and Nippon Shinyaku Co., Ltd. (collectively, "NS") is successful, we intend to commercialize Deramiocel in the United States directly or through distributors, and we may also seek commercialization through strategic partners in other select international markets.

Our development efforts for Deramiocel for the treatment of DMD have progressed through multiple clinical studies, and we continue activities to support regulatory review and potential approval in the United States, as well as commercialization preparation, if approved.

Cell Therapy (Deramiocel)

Our core program is focused on the development and commercialization of Deramiocel, a cell therapy product candidate comprised of cardiosphere-derived cells ("CDCs"), a population of cardiac-derived stromal cells isolated from qualified donated human hearts. Deramiocel is designed to slow disease progression in DMD through immunomodulatory, anti-inflammatory, pro-angiogenic and anti-fibrotic activities of CDCs. These effects are mediated in part by exosomes secreted by CDCs that contain bioactive molecules, including microRNAs and other signaling factors, which may influence gene expression and cellular pathways involved in inflammation, fibrosis, and tissue repair.

Our clinical development program for Deramiocel has focused on adolescents and young adults with DMD, including many patients who are non-ambulatory and experiencing progressive cardiac and skeletal muscle decline. We believe therapies that address inflammatory and fibrotic processes contributing to muscle degeneration may provide potential benefit across a broad population of individuals with DMD.

Exosomes Platform Technology (StealthX^TM)

Extracellular vesicles ("EVs"), including exosomes and microvesicles, are nano-scale membrane-enclosed vesicles secreted by many cell types that contain characteristic lipids, proteins and nucleic acids, including messenger

RNA and microRNAs. These vesicles facilitate intercellular communication through the binding and activation of membrane receptors or through the delivery of molecular cargo into target cells. Through these mechanisms, EVs may influence a variety of biological processes, including cell survival, proliferation, inflammation and tissue repair.

Exosomes in particular have attracted increasing interest as potential therapeutic and diagnostic platforms. Their small size, generally low immunogenicity, and ability to deliver biologically active molecules to recipient cells may allow them to modulate complex biological pathways. Because exosomes are cell-free vesicles, they may be stored, handled, and administered using approaches similar to those used for certain established biologic therapies.

Our exosome platform is supported by internal research and external collaborations. Our collaborations and research around exosomes include the National Institutes of Health, the National Institute of Allergy and Infectious Diseases ("NIAID"), Johns Hopkins University ("JHU"), the Department of Defense, the U.S. Army Institute of Surgical Research, and Cedars-Sinai Medical Center ("CSMC"). Our platform leverages advances in RNA biology, protein engineering and targeted delivery technologies to support the development of exosome-based therapeutics and vaccines. We are currently exploring exosome-based approaches for infectious diseases, monogenic diseases and other potential indications.

Our current strategy is focused on advancing these programs through collaborations and partnerships that may provide additional development resources and capital to support potential clinical development.

Our Pipeline - Key Programs

Deramiocel: Duchenne Muscular Dystrophy Program: Deramiocel is Capricor's lead product candidate and is being developed for the treatment of DMD, a rare, progressive genetic disease characterized by degeneration of skeletal and cardiac muscle.

Deramiocel's mechanism of action is distinct from mutation-targeted approaches such as exon-skipping oligonucleotides and gene therapies, which aim to restore dystrophin expression in muscle cells. DMD is caused by mutations in the dystrophin gene that impair production of functional dystrophin, a structural protein important for maintaining muscle integrity. The absence of functional dystrophin leads to progressive skeletal and cardiac muscle damage, muscle cell death and replacement of muscle tissue with fibrosis. Cardiac involvement is a major component of disease progression in DMD. In patients with DMD, heart muscle cells progressively deteriorate and are replaced with scar tissue, leading to cardiomyopathy and ultimately heart failure, which is a leading cause of mortality in individuals with DMD. While several therapies have been developed to address certain genetic mutations associated with DMD, significant unmet medical need remains, particularly in patients with established skeletal and cardiac muscle disease.

We have conducted a comprehensive clinical development program evaluating Deramiocel in patients with DMD, including randomized controlled trials and long-term follow-up studies designed to assess safety and efficacy across multiple measures of disease progression. These studies include the Phase 3 HOPE-3 trial, the Phase 2 HOPE-2 trial and its ongoing open-label extension, and the earlier Phase I/II HOPE-Duchenne clinical trial.

Biologics License Application: In late 2024, we completed our submission of a BLA to the FDA seeking approval of Deramiocel for the treatment of DMD. The FDA accepted the BLA for review, granted Priority Review, and assigned a PDUFA target action date of August 31, 2025. In July 2025, we received a Complete Response Letter ("CRL") from the FDA stating that the application did not meet the statutory requirement for substantial evidence of effectiveness and requesting additional clinical data.

Following a Type A meeting with the FDA in August 2025, we aligned with the Agency on a regulatory path forward to address the CRL, including the submission of additional clinical data from the Phase 3 HOPE-3 trial. We subsequently submitted our response to the CRL, which the FDA accepted as a complete response and classified as a Class

2 resubmission, assigning a new PDUFA target action date of August 22, 2026. If approved, Deramiocel has the potential to become the first therapy designed to address both skeletal and cardiac muscle manifestations of DMD.

In parallel with our U.S. regulatory activities, we have initiated regulatory engagement in Europe and Japan and are working with the relevant health authorities to determine the most appropriate regulatory pathway for Deramiocel in those regions.

StealthX™ Exosome Platform: Our StealthX™ exosome platform program consists of engineered exosomes for vaccine and therapeutic development.

Exosome Platform: Engineered Exosome-Based Vaccines: The StealthX™ vaccine is a proprietary vaccine developed internally by Capricor utilizing exosomes that were engineered to express either spike or nucleocapsid proteins on the surface. Preclinical results from murine and rabbit models published in the peer-reviewed journal, Microbiology Spectrum, showed the StealthX™ vaccine resulted in robust antibody production, potent neutralizing antibodies, a strong T-cell response and a favorable safety profile. We were selected to be part of Project NextGen, an initiative by the U.S. Department of Health and Human Services to advance a pipeline of new, innovative vaccines providing broader and more durable protection for COVID-19. As part of Project NextGen, the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, is conducting a Phase 1 clinical study with our StealthX™ vaccine. Preliminary data indicated the StealthX™ vaccine has been generally well tolerated and demonstrated a favorable safety profile across all dose levels tested. Early analyses showed limited neutralizing antibody responses at the evaluated dose levels, which may reflect prior vaccination or infection among trial participants. Final results from the trial, including cellular immune response data, are expected later in 2026, subject to completion of the study by NIAID. If NIAID finds that our StealthX™ vaccine meets its criteria for safety and efficacy, they may consider our program for a funded Phase 2 study.

Exosome Platform: Engineered Exosome-Based Therapeutics: We are focused on developing a precision-engineered exosome platform technology that has the potential to deliver defined sets of effector molecules that exert their effects through defined mechanisms of action. At this time, we are exploring the use of our proprietary StealthX™ exosome platform for a broad range of therapeutic applications including targeted RNA, protein and small molecule therapeutics to treat or prevent a variety of diseases.

These programs represent our core technology and products.

Financial Operations Overview

As of March 31, 2026, we had cash, cash equivalents, and marketable securities totaling approximately $278.6 million. Since our inception, we have received approximately $600 million through a combination of equity financings, strategic collaborations, grants and other non-dilutive funding sources.

Due to our significant research and development expenditures, and general administrative costs associated with our operations, we have generated substantial operating losses in each period since our inception. Our net losses were approximately $33.9 million and approximately $24.4 million, for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, we had an accumulated deficit of approximately $338.8 million. We expect to incur significant expenses and operating losses for the foreseeable future.

As we seek to develop and commercialize Deramiocel or any other product candidates including those related to our exosomes program, we anticipate that our expenses will increase significantly and that we will need additional funding to support our continuing operations. Until such time when we can generate significant revenue from product sales, if ever, we expect to finance our operations through a combination of public or private equity financings, debt financings or other sources, which may include licensing agreements or strategic collaborations or other distribution agreements. We may be unable to raise additional funds or enter into such agreements or arrangements when needed on favorable terms, if at all. If we fail to raise capital or other potential funding or enter into such agreements as and when needed, we may have to significantly delay, scale back or discontinue the development or commercialization of Deramiocel or our other product candidates.

We have no commercial product sales to date and will not have the ability to generate any commercial product revenue until after we have received approval from the FDA or equivalent foreign regulatory bodies to begin selling our product candidates. Developing biological products is a lengthy and very expensive process. To date, most of our development expenses have related to our product candidates, consisting of Deramiocel and our exosome technologies. As we proceed with the clinical development and potential commercialization of Deramiocel, and as we further develop our exosome technologies, our expenses will further increase. Accordingly, our success depends not only on the safety and efficacy of our product candidates, but also on our ability to finance the development of our products and our clinical programs. Our recent major sources of working capital have been primarily proceeds from public equity sales of securities and upfront payments pursuant to our U.S. and Japan Distribution Agreements with Nippon Shinyaku. While we pursue our preclinical and clinical programs, we continue to explore potential partnerships for the development of one or more of our product candidates in the U.S. and in other territories across the world, subject to the rights of Nippon Shinyaku and the outcome of our litigation against NS.

Our results have included non-cash compensation expense due to the issuance of stock awards and warrants, as applicable. We expense the fair value of stock awards and warrants over their vesting period as applicable. When more precise pricing data is unavailable, we determine the fair value of stock options using the Black-Scholes option-pricing model. The terms and vesting schedules for share-based awards vary by type of grant and the employment status of the grantee. Generally, the stock awards vest based upon time-based conditions. Stock-based compensation expense is included in the condensed consolidated statements of operations under general and administrative ("G&A") or research and development ("R&D") expenses, as applicable. We expect to record additional non-cash compensation expense in the future, which may be significant.

Results of Operations

Revenue

Clinical Development Income. Clinical development income for the three months ended March 31, 2026 and 2025 was zero.

Operating Expenses

Research and Development Expenses. R&D expenses consist primarily of compensation and other related personnel costs, supplies, clinical trial costs, patient treatment costs, rent for laboratories and manufacturing facilities, consulting fees, costs of personnel and supplies for manufacturing, costs of service providers for preclinical, clinical and manufacturing, certain legal expenses resulting from intellectual property prosecution, stock-based compensation expense and other expenses relating to the design, development, testing and enhancement of our product candidates.

The following table summarizes our R&D expenses by category for each of the periods indicated:

​

R&D expenses for the three months ended March 31, 2026 increased by approximately $8.5 million, or 45%, compared to the three months ended March 31, 2025. The increase was primarily driven by the following:

The increase was partially offset by a $0.7 million decrease in research expenses related to our exosomes platform, primarily related to timing of research activities for exosomes.

General and Administrative Expenses. G&A expenses consist primarily of compensation and other related personnel expenses for executive, finance and other administrative personnel, stock-based compensation expense, accounting, legal and other professional fees, consulting expenses, rent for corporate offices, business insurance and other corporate expenses.

The following table summarizes our G&A expenses by category for each of the periods indicated:

​

G&A expenses for the three months ended March 31, 2026 increased by approximately $3.3 million, or 55%, compared to the three months ended March 31, 2025. The increase was primarily driven by the following:

​

The increase was partially offset by a $0.2 million decrease in stock-based compensation expense primarily due to timing of recognition of stock-based compensation expenses.

​

Other Income (Expense)

Investment Income. Investment income for the three months ended March 31, 2026 and 2025 was approximately $2.9 million and $0.7 million, respectively. The increase in investment income for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025 is due to a higher principal balance in our marketable securities, savings and money market fund accounts.

Products Under Active Development

Deramiocel for the treatment of DMD - The expenses for our DMD program include costs for personnel, clinical, regulatory, commercial, and research activities, including expenses related to scale-up for potential commercial scale manufacturing if our Deramiocel product is approved. In 2026, we expect to spend approximately $100.0 million to $125.0 million primarily consisting of CMC expansion, product inventory buildout, clinical, regulatory and pre-commercial expenses for our Deramiocel program.

Exosome Platform - Our exosome platform is in early-stage development. We expect to spend approximately $7.0 million to $10.0 million during 2026 on development expenses related to our exosomes program, which includes personnel, preclinical studies and manufacturing related expenses for these technologies. Our expenses are primarily focused on the expansion of our engineered exosome platform for therapeutic development.

Our expenditures on current and future clinical development programs, particularly our Deramiocel and exosomes programs, cannot be predicted with any significant degree of certainty as they are dependent on the results of our current trials and our ability to secure additional funding and/or strategic partners. In particular, our expenditures on the commercialization of Deramiocel, if approved, will heavily depend on the outcome of our litigation with NS and, if we are successful in such litigation, whether we commercialize Deramiocel in the United States directly or through one or more distributors. Further, we cannot predict with any significant degree of certainty the amount of time which will be required to complete our clinical trials, the costs of completing research and development projects or whether, when and to what extent we will generate revenues from the commercialization and sale of any of our product candidates. The duration and cost of clinical trials may vary significantly over the life of a project as a result of unanticipated events arising during manufacturing and clinical development and as a result of a variety of other factors, including:

​

Liquidity and Capital Resources

The following table summarizes our liquidity and capital resources as of March 31, 2026 and December 31, 2025 and our net increase (decrease) in cash, cash equivalents, and marketable securities for the three months ended March 31, 2026 and 2025 and is intended to supplement the more detailed discussion that follows. The amounts stated in the tables below are expressed in thousands. We believe that our current cash, cash equivalents, and marketable securities are sufficient to fund our operating capital requirements for at least the next twelve months from the issuance date of these condensed consolidated financial statements.

​

​

​

Our total cash, cash equivalents and marketable securities as of March 31, 2026 were approximately $278.6 million compared to approximately $318.1 million as of December 31, 2025. The decrease in cash, cash equivalents and marketable securities from December 31, 2025 to March 31, 2026 is primarily due to our continuing efforts in preparing the Company for potential commercialization. As of March 31, 2026, we had approximately $47.6 million in total liabilities, consisting of approximately $14.8 million in lease liabilities, approximately $14.5 million in accounts payable and accrued expenses, $12.0 million relates to deferred revenue, and $6.3 million in CIRM liability, with net working capital of approximately $249.5 million.

Cash used in operating activities was approximately $29.3 million and approximately $6.4 million for the three months ended March 31, 2026 and 2025, respectively. The increase of approximately $22.8 million in cash used in operating activities is due to an approximately $9.5 million increase in net loss for the three months ended March 31, 2026 as compared to the same period in 2025. Furthermore, there was an increase of approximately $10.2 million in the change in receivables balances, as well as $4.4 million in the change in accounts payable and accrued expenses balances for the three months ended March 31, 2026 as compared to the same period in 2025. To the extent we obtain sufficient capital and/or long-term debt funding and are able to continue developing our product candidates, including if we expand our platform technology portfolio, engage in further research and development activities, and, in particular, conduct preclinical studies and clinical trials, we expect to continue incurring substantial losses.

We had cash flow used in investing activities of approximately $154.6 million for the three months ended March 31, 2026 and cash flow provided by investing activities of approximately $23.9 million for the three months ended March 31, 2025. The change in investing activities for the three months ended March 31, 2026 as compared to the same period of 2025 is due to the net effect from purchases, sales and maturities of marketable securities and the purchase of approximately $10.8 million in property and equipment, leasehold improvements and construction in progress in the three months ended March 31, 2026, compared to approximately $1.1 million in the three months ended March 31, 2025.

We had cash flow provided by financing activities of approximately $1.5 million and $0.1 million for the three months ended March 31, 2026 and 2025, respectively. The increase in cash provided by financing activities for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025 is primarily due to the net proceeds from the exercises of stock options.

From inception through March 31, 2026, we financed our operations primarily through private and public sales of our equity securities, government grants, and payments from distribution agreements and collaboration partners.

We may seek to raise additional funds through various potential sources, such as equity and debt financings, government grants, or through strategic collaborations and license agreements or other distribution agreements. We can give no assurances that we will be able to secure such additional sources of funds to support our operations, complete our clinical trials or if such funds become available to us, that such additional financing will be sufficient to meet our needs. Moreover, to the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates or grant licenses on terms that may not be favorable to us.

Our estimates regarding the sufficiency of our financial resources are based on assumptions that may prove to be wrong. We may need to obtain additional funds sooner than planned or in greater amounts than we currently anticipate. The actual amount of funds we will need to operate is subject to many factors, some of which are beyond our control. These factors include the following:

Collaborations

Commercialization and Distribution Agreement (Nippon Shinyaku - United States)

On January 24, 2022, Capricor entered into the U.S. Distribution Agreement with Nippon Shinyaku, a Japanese corporation. Under the terms of the U.S. Distribution Agreement, Capricor appointed Nippon Shinyaku as its exclusive distributor in the United States of Deramiocel for the treatment of DMD.

The Company has filed a Complaint for Equitable Relief and Application for Preliminary Injunction (the "Complaint") in the Superior Court of New Jersey, Chancery Division, Bergen County. The Complaint alleges a fundamental pricing flaw in the U.S. Distribution Agreement and that the defendants named therein, NS, have failed to adequately prepare for the commercial launch of the Company's product Deramiocel in the United States pursuant to the U.S. Distribution Agreement, and have otherwise materially breached the terms of the U.S. Distribution Agreement. In the Complaint, the Company seeks rescission of the U.S. Distribution Agreement, declaratory judgment that the Company has the right to distribute Deramiocel directly or through distributors other than NS, and other equitable remedies

Commercialization and Distribution Agreement (Nippon Shinyaku - Japan)

On February 10, 2023, Capricor entered into a Commercialization and Distribution Agreement (the "Japan Distribution Agreement") with Nippon Shinyaku. Under the terms of the Japan Distribution Agreement, Capricor appointed Nippon Shinyaku as its exclusive distributor in Japan of Deramiocel for the treatment of DMD.

Under the terms of the Japan Distribution Agreement, Capricor received an upfront payment of $12.0 million in 2023 and in addition, Capricor will potentially receive additional development and sales-based milestone payments of up to approximately $89.0 million, subject to foreign currency exchange rates, and a meaningful double-digit share of product revenue. Nippon Shinyaku will be responsible for the distribution of Deramiocel in Japan. Capricor will be responsible for the conduct of clinical development and regulatory approval in Japan, as may be required, as well as the manufacturing of Deramiocel. Subject to regulatory approval, Capricor or its designee will hold the Marketing Authorization in Japan if the product is approved in that territory.

European Region Binding Term Sheet

​

On September 16, 2024, the Company entered into a binding term sheet with Nippon Shinyaku for the potential commercialization and distribution of Deramiocel for the treatment of DMD in Europe. The term sheet contemplated that the Company would be responsible for development and manufacturing, and Nippon Shinyaku would be responsible for sales and distribution in the European region, subject to execution of a definitive agreement and regulatory approval. As of March 31, 2026, no definitive agreement had been executed and the Company had not recognized any revenue, received any consideration, or recorded any amounts in connection with the term sheet. The term sheet expired in accordance with its terms on April 1, 2026.

Financing Activities by the Company

December 2025 Underwritten Public Offering

On December 5, 2025, the Company entered into an underwriting agreement with Piper Sandler & Co. and Oppenheimer & Co., Inc. as representatives of the underwriters (the "Underwriters"), pursuant to which the Company agreed to sell and issue, in a public offering an aggregate of 6,000,000 shares of common stock, including the exercise in full of the underwriters' option to purchase an additional 900,000 shares to cover over allotments, at a public offering price of $25.00 per share for total gross proceeds of approximately $172.5 million, before deducting underwriting commissions and other offering expenses payable by the Company. The Company paid cash commissions on the gross proceeds, plus reimbursement of expenses to the Underwriters, as well as legal and accounting fees in the aggregate amount of approximately $10.5 million.

​

September 2025 ATM Program

On September 10, 2025, the Company established an at-the-market offering under a prospectus supplement for aggregate sales proceeds of up to $150.0 million (the "September 2025 ATM Program"), pursuant to an Equity Distribution Agreement with Piper Sandler and Oppenheimer (collectively, the "Agents") by which the Agents may sell our common stock at the market prices prevailing at the time of sale. The Agents are entitled to compensation for their services at a commission rate of 3.0% of the gross sales price per share of common stock sold plus reimbursement of certain expenses. Effective December 5, 2025, the Company reduced the maximum offering amount from $150.0 million to $125.0 million.

Through March 31, 2026, the Company sold an aggregate of 2,682,307 shares of common stock under the September 2025 ATM Program at an average price of approximately $28.89 per share for gross proceeds of approximately $77.5 million. The Company paid approximately $2.4 million of aggregated fees related to this sale. From January 1, 2026 through the date of this filing, no additional shares have been sold under the September 2025 ATM Program.

​

CIRM Grant Award

On June 16, 2016, Capricor entered into an award agreement with the California Institute for Regenerative Medicine ("CIRM") for approximately $3.4 million to support, in part, the Company's Phase I/II HOPE-Duchenne clinical trial of Deramiocel for the treatment of DMD-associated cardiomyopathy. The award was subject to operational milestones, a co-funding requirement, and certain reporting, intellectual property and revenue-sharing obligations under CIRM's clinical-stage award policies. The Company completed all milestones and close-out activities associated with the award in 2019 and expended all funds received.

The Company accounts for the award as a liability rather than income because the Company had the option to convert the award into a loan. In February 2025, the Company notified CIRM of its election to convert the award into a loan. In April 2026, the Company and CIRM were finalizing documentation for a loan repayment agreement providing for repayment in two tranches: approximately $3.4 million due within three calendar days following execution of the agreement, and approximately $2.9 million due no later than June 12, 2026. As of March 31, 2026, the total repayment amount of approximately $6.3 million, consisting of $3.4 million in principal and $2.9 million in accrued interest, was recorded as a current liability in the condensed consolidated balance sheet.

Off-Balance Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Critical Accounting Policies and Estimates

Our financial statements are prepared in accordance with generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis, including research and development and clinical trial accruals, and stock-based compensation estimates. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates. We believe the following critical accounting policies reflect the more significant judgments and estimates used in the preparation of our financial statements and accompanying notes.

Leases

The Company accounts for its leases in accordance with ASC Topic 842, Leases ("ASC 842"), which requires lessees to recognize most leases on the balance sheet with a corresponding right-to-use asset ("ROU asset") and a lease liability for most leases. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at lease commencement based on present value of fixed lease payments over the lease term.

​

Leases are classified as either financing or operating leases. The Company's leases are primarily operating leases. The Company elects the short-term lease exemption for leases with a term of twelve months or less.

​

The Company uses its incremental borrowing rate to measure lease liabilities when the implicit rate is not readily determinable.

​

The Company has elected the practical expedient to combine lease and non-lease components for real estate leases. This practical expedient is not elected for manufacturing facilities and equipment embedded in product supply arrangements.

​

Revenue Recognition

The Company recognizes revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"), using a five-step model to recognize revenue when control of promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled. The Company's arrangements may include fixed consideration, such as upfront payments and milestones, as well as variable consideration, such as sales-based royalties and shared revenues. Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty is resolved.

​

Revenue is recognized either at a point in time or over time, depending on when control of the promised goods or services is transferred to the customer. For performance obligations satisfied over time, the Company recognizes revenue based on a measure of progress that depicts the transfer of services to the customer. Upfront payments received in advance of performance are recorded as deferred revenue.

​

Research and Development Expenses and Accruals

R&D expenses consist primarily of salaries and related personnel costs, supplies, clinical trial costs, patient treatment costs, rent for laboratories and manufacturing facilities, consulting fees, costs of personnel and supplies for manufacturing, costs of service providers for preclinical, clinical, manufacturing and commercial activities, and certain legal expenses resulting from intellectual property prosecution, stock compensation expense and other expenses relating to the design, development, testing and enhancement of our product candidates. Except for certain capitalized intangible assets, R&D costs are expensed as incurred.

Our cost accruals for clinical trials and other R&D activities are based on estimates of the services received and efforts expended pursuant to contracts with numerous clinical trial centers and contract research organizations ("CROs"), clinical study sites, laboratories, consultants or other clinical trial vendors that perform activities in connection with a trial. Related contracts vary significantly in length and may be for a fixed amount, a variable amount based on actual costs incurred, capped at a certain limit, or for a combination of fixed, variable and capped amounts. Activity levels are monitored through close communication with the CROs and other clinical trial vendors, including detailed invoice and task completion review, analysis of expenses against budgeted amounts, analysis of work performed against approved contract budgets and payment schedules, and recognition of any changes in scope of the services to be performed. Certain CRO and significant clinical trial vendors provide an estimate of costs incurred but not invoiced at the end of each quarter for each individual trial. These estimates are reviewed and discussed with the CRO or vendor as necessary, and are included in R&D expenses for the related period. For clinical study sites which are paid periodically on a per-subject basis to the institutions performing the clinical study, we accrue an estimated amount based on subject screening and enrollment in each quarter. All estimates may differ significantly from the actual amount subsequently invoiced, which may occur several months after the related services were performed.

In the normal course of business, we contract with third parties to perform various R&D activities in the ongoing development of our product candidates. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under the contracts depend on factors such as the achievement of certain events, the successful enrollment of patients, and the completion of portions of the clinical trial or

similar conditions. The objective of the accrual policy is to match the recording of expenses in the financial statements to the actual services received and efforts expended. As such, expense accruals related to clinical trials and other R&D activities are recognized based on our estimates of the degree of completion of the event or events specified in the applicable contract.

No adjustments for material changes in estimates have been recognized in any period presented.

Stock-Based Compensation

Our results include non-cash compensation expense related to stock options and restricted stock awards granted to employees, directors and consultants. The Company has six equity plans; however, it currently issues awards only under the 2020 Equity Incentive Plan, the 2021 Equity Incentive Plan, and the 2025 Equity Incentive Plan. The Company no longer issues awards under the 2006 Stock Option Plan, the 2012 Restated Equity Incentive Plan or the 2012 Non-Employee Director Stock Option Plan.

We expense the fair value of stock-based compensation over the vesting period. For stock options, when more precise pricing data is unavailable, we determine the fair value using the Black-Scholes option-pricing model. This valuation model requires us to make assumptions and judgments about the variables used in the calculation. These variables and assumptions include the weighted-average period of time that the options granted are expected to be outstanding, the volatility of our common stock, and the risk-free interest rate. We account for forfeitures upon occurrence. For restricted stock awards, we determine the fair value using the Company's stock price at the grant date.

The terms and vesting schedules for share-based awards vary by type of grant and the employment status of the grantee. Generally, the awards vest based upon time-based conditions. Stock-based compensation expense is included in general and administrative expense or research and development expense, as applicable, in the Statements of Operations and Comprehensive Income (Loss). We expect to record additional non-cash compensation expense in the future, which may be significant.

Clinical Trial Expense

As part of the process of preparing our condensed consolidated financial statements, we are required to estimate our accrued expenses. Our clinical trial accrual process is designed to account for expenses resulting from our obligations under contracts with vendors, consultants, contract research organizations ("CROs"), and clinical site agreements in connection with conducting clinical trials. The financial terms of these contracts are subject to negotiations which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided to us under such contracts. Our objective is to reflect the appropriate clinical trial expenses in our condensed consolidated financial statements by matching the appropriate expenses with the period in which services are provided and efforts are expended. We account for these expenses according to the progress of the trial as measured by patient progression and the timing of various aspects of the trial. We determine accrual estimates through financial models that take into account discussions with applicable personnel and outside service providers as to the progress or state of completion of trials, or the services completed. During the course of a clinical trial, we adjust our clinical expense recognition if actual results differ from our estimates. We make estimates of our accrued expenses as of each balance sheet date in our condensed consolidated financial statements based on the facts and circumstances known to us at that time. Our clinical trial accrual and prepaid assets are dependent, in part, upon the receipt of timely and accurate reporting from CROs and other third-party vendors. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us reporting amounts that are too high or too low for any particular period.

Recently Issued or Newly Adopted Accounting Pronouncements

In December 2024, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (Topic 740), which requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as additional information on income taxes paid. ASU 2023-09 is effective on a prospective basis for annual periods beginning after

December 15, 2024. The Company adopted ASU 2023-09 in the fourth quarter of 2025 and applied it retrospectively. Please refer to Note 13 - "Income Taxes" for further information and disclosure.

​

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which is intended to improve the navigability of the guidance in ASC 270, Interim Reporting, and clarify when it applies. Under the amendments, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with GAAP. ASU 2025-11 also addresses the form and content of such financial statements, interim disclosures requirements, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, and early adoption is permitted. The Company is currently evaluating the impact of this ASU on its financial statements.

​

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which amends the guidance in ASC 350-40, Intangibles - Goodwill and Other - Internal-Use Software. The amendments modernize the recognition and disclosure framework for internal-use software costs, removing the previous "development stage" model and introducing a more judgment-based approach. The ASU is effective for fiscal years beginning after December 15, 2027, and for interim periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its financial statements.

​

In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40). The ASU requires the disaggregated disclosure of specific expense categories, including purchases of inventory, employee compensation, depreciation, and amortization, within relevant income statement captions. This ASU also requires disclosure of the total amount of selling expenses along with the definition of selling expenses. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Adoption of this ASU can either be applied prospectively to consolidated financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the consolidated financial statements. Early adoption is also permitted. This ASU will likely result in the required additional disclosures being included in our consolidated financial statements, once adopted. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures.

Other recent accounting pronouncements issued by the Financial Accounting Standards Board, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the SEC, did not or are not believed by management to have a material impact on the Company's present or future consolidated financial statement presentation or disclosures.
