ITEM 1A. RISK FACTORS.

Investing in our securities involves a high degree of risk. You should carefully consider the risks described below, any of which may be relevant to decisions regarding an investment in or ownership of our stock. The occurrence of any of these risks could have a significant adverse effect on our reputation, business, financial condition, results of operations, growth, and ability to accomplish our strategic objectives. We have organized the description of these risks into groupings in an effort to enhance readability, but many of the risks interrelate or could be grouped or ordered in other ways, so no special significance should be attributed to the groupings or order below.

Risk Factor Summary

Risks Related to Our Financial Condition and Capital Requirements

•We are a vertically-integrated commercial stage biotechnology company with a single approved product and a limited operating history as a commercial company and have many other product candidates at the clinical stage. We have a history of operating losses, and we expect to continue to incur losses and may never be profitable, which, together with our limited operating history, makes it difficult to assess our future viability.

•We anticipate needing additional financing to fund our operations, complete the commercialization of our approved product, conduct clinical trials, and develop and commercialize our other product candidates.

•The RIPA imposes Revenue Interest Payment obligations, which may adversely affect our financial position and results of operations, as well as affirmative and negative covenants, which restrict our business operations.

•Our debt and revenue interest liability could adversely affect our cash flows and limit our flexibility to raise additional capital.

•The value of our warrants outstanding and the revenue interest liability are subject to potentially material increases and decreases based on fluctuations in the price of our common stock or projected sales and the probability of specific events, which may affect our results of operations and financial position and could adversely affect our stock price.

Risks Related to the Discovery, Development and Commercialization of our Approved Product and our Other Product Candidates

•We are substantially dependent on the successful commercialization of our approved product and the success and regulatory approval of our other product candidates. If we are unable to successfully commercialize our approved product or successfully complete clinical development of, obtain regulatory approval for, or commercialize, our other product candidates, or if we experience delays in doing so, our business will be materially harmed.

•We have limited experience as a commercial company and the sales, marketing, and distribution of our approved product or any future approved products may be unsuccessful or less successful than anticipated.

•We have developed an approved product and are developing other product candidates in combination with other therapies, which expose us to additional risks.

Risks Related to Reliance on Third Parties

•We have relied and will continue to rely on third parties and related parties to conduct some of our preclinical studies and clinical trials, manufacture products, and perform many essential services for any products that we commercialize. Any failure by a third party or related party to perform as expected, to comply with legal and regulatory requirements, to manufacture products in compliance with cGMP, or to conduct the clinical trials according to GCP guidelines, and in a timely manner, may delay or prevent our ability to commercialize our approved product, to seek or obtain regulatory approval for or commercialize our other product candidates or may subject us to regulatory sanctions.

•If third-party manufacturers, wholesalers and distributors fail to perform as expected, or fail to devote sufficient time and resources to our approved product or other product candidates, our clinical development may be delayed, our costs may be higher than expected or our other product candidates may fail to be approved, or we may fail to successfully commercialize our approved product or any other product candidates if approved.

Table of Contents

•We use the Clinic, a related party, in some of our clinical trials which may expose us to significant regulatory risks. If our data for this site is not sufficiently robust or if there are any data integrity issues, we may be required to repeat such studies or contract with other clinical trial sites, which could delay and/or increase the cost of our development plans.

•We have formed, and may in the future form or seek, strategic alliances or enter into collaborations with third parties or additional licensing arrangements, and we may not realize the benefits of such alliances or licensing arrangements, and we may engage in disputes with such third parties, which can be costly and time consuming.

Risks Related to Healthcare and Other Government Regulations

•While we have one FDA-approved product, we may be unable to obtain additional U.S. or foreign regulatory approval and, as a result, may be unable to commercialize our other product candidates. We are and will continue to be subject to ongoing extensive regulation, regulatory obligations and continued regulatory review, which may result in significant additional expense.

•Obtaining and maintaining regulatory approval of our approved product or other product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval in other jurisdictions.

•Even though we have a regulatory approved product, we will continue to be subject to ongoing regulatory requirements concerning it and our other product candidates which may result in significant additional expenses. Additionally, our other product candidates, if approved, could be subject to labeling and other restrictions, and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our approved product or product candidates.

•If we are unable to establish adequate sales, marketing and distribution capabilities, we may not be successful in commercializing our approved product or other product candidates if and when they are approved.

•Problems related to large-scale commercial manufacturing could cause delays in product launches, an increase in product costs, product recalls or product shortages.

Risks Related to Intellectual Property

•If we are unable to obtain, maintain, protect and enforce patent protection and other proprietary rights for our approved product and our other product candidates and technologies, we may not be able to compete effectively or operate profitably and our ability to prevent our competitors from commercializing similar or identical technology and we would be adversely affected.

•If any of our owned or in-licensed patent applications do not issue as patents in any jurisdiction, we may not be able to compete effectively.

•We or our licensors, collaborators, or any future strategic partners may become subject to third-party claims or litigation alleging infringement of patents or other proprietary rights or seeking to invalidate patents or other proprietary rights, and we may need to resort to litigation to protect or enforce our patents or other intellectual property or the patents or other intellectual property of our licensors, all of which could be expensive, time-consuming and unsuccessful, may delay or prevent the development and commercialization of our approved product and other product candidates, or may put our patents and other proprietary rights at risk.

Risks Related to Our Common Stock

•Dr. Soon-Shiong, our Founder, Executive Chairman, Global Chief Scientific and Medical Officer and principal stockholder, has significant interests in other companies which may conflict with our interests.

•Dr. Soon-Shiong, through his voting control of the company, has the ability to control actions that require stockholder approval.

•Conversion of related-party promissory notes, exercise of outstanding warrants and options to purchase our common stock, the achievement of the milestone under our outstanding CVRs, and potential additional equity issuances may dilute the ownership interest of existing stockholders or may otherwise depress the price of our common stock.

•The market price of our common stock has been and may continue to be volatile, and investors may have difficulty selling their shares.

Risks Related to Our Financial Condition and Capital Requirements

We are a vertically-integrated commercial stage biotechnology company with a single approved product and a limited operating history as a commercial company and have many other product candidates at the clinical stage. We have a history of operating losses, and we expect to continue to incur losses and may never be profitable, which, together with our limited operating history, makes it difficult to assess our future viability.

We are a vertically-integrated commercial stage biotechnology company with a limited operating history as a commercial company upon which you can evaluate our business and prospects regarding the commercialization of our approved product, and we have a broad portfolio of product candidates at various stages of development. Prior to the approval of ANKTIVA for commercial sale, we primarily generated revenues from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables, and grant programs. The company expects to continue to generate revenue from these programs.

On April 22, 2024, the FDA approved ANKTIVA with BCG for the treatment of adult patients with BCG-unresponsive NMIBC with CIS with or without papillary tumors for commercial sale, and we have commenced generating revenue, although we expect it to take some time to generate significant revenue from our approved product. We can provide no assurance when, or if, this will occur. We do not expect additional revenue from our other product candidates unless and until we obtain regulatory approval of and commercialize any of such other product candidates, and we do not know when, or if, this will occur. In addition, we have limited experience and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biotechnology industry, including in connection with obtaining marketing approvals, manufacturing a commercial-scale product or arranging for a third party to do so on our behalf, and conducting sales and marketingactivities necessary for successful product commercialization. Because of the numerous risks and uncertainties associated with the commercialization of our approved product and other development efforts, we are unable to predict when we may become profitable, if at all.

Since the commencement of our operations, we have incurred significant losses each year, and, as of December 31, 2024, we had an accumulated deficit of $3.4 billion. We expect to continue to incur significant expenses as we seek to expand our business, including in connection with conducting research and development across multiple therapeutic areas, participating in clinical trial activities, continuing to acquire or in-license technologies, maintaining, protecting and expanding our intellectual property, seeking regulatory approvals, increasing our manufacturing capabilities and, upon successful receipt of FDA approval, commercializing our other product candidates. Furthermore, the timing and magnitude of sales of our approved product and other revenues remain uncertain and may take a significant amount of time to materialize.

We expect our expenses and net losses to increase significantly as we continue to commercialize our approved product, continue to develop and seek regulatory approvals for our other product candidates, and plan to commercialize other approved products, if any, as well as hire additional personnel, protect our intellectual property and incur additional costs associated with operating as a public company. Since ANKTIVA is approved for use with BCG (and currently TICE BCG is the only FDA-approved strain of BCG available in the U.S., except for rBCG available in limited quantities through our agreement with Serum Institute pursuant to an EAP), any shortage or supply chain issues associated with TICE BCG could impact the demand for ANKTIVA and our ability to commercialize our approved product.

Our net losses may fluctuate significantly from quarter to quarter and year to year, depending on sales, the timing of our clinical studies and trials, associated manufacturing needs, commercialization activities of our approved product, and any of our other product candidates, if they are approved, and our expenditures on other research and development activities.

We also face the risks associated with the shift from development to commercialization of new products based on innovative technologies. Our ability to achieve profitability, if ever, is dependent upon, among other things, obtaining regulatory approvals for additional product candidates and successfully commercializing our approved product, and other product candidates alone or with third parties. However, our operations may not become profitable even with commercial sales of our approved product or other product candidates, even if they are successfully developed, approved and thereafter commercialized. Even if we do become profitable, we may not be able to sustain or increase our profitability on a quarterly or annual basis. As a result, it may be more difficult for you to assess our future viability than it could have been if we had a longer operating history.

We anticipate needing additional financing to fund our operations, complete the commercialization of our approved product, conduct clinical trials, and develop and commercialize our other product candidates. If we are unable to obtain such financing when needed or on acceptable terms, we may be unable to successfully commercialize our approved product or develop and commercialize our other product candidates. If we are unable to obtain such financing when needed or on acceptable terms, we could be forced to delay, limit, reduce, or terminate our development programs, commercialization efforts, and/or other operations.

The development of biopharmaceutical products, including conducting preclinical studies and clinical trials, is a very time-consuming, expensive and uncertain process that takes years to complete. Our operations have consumed substantial amounts of cash since inception. A significant portion of our funding has been in the form of related-party promissory notes. As of December 31, 2024, our indebtedness was comprised of a $505.0 million convertible promissory note held by an entity affiliated with Dr. Soon-Shiong.

As of December 31, 2024, we held cash and cash equivalents, and marketable securities totaling $149.8 million. We will need to obtain additional financing to fund our future operations, including the commercialization of our approved product and the development and commercialization of our other product candidates. Changing circumstances may cause us to increase our spending significantly faster than we currently anticipate and we may need to raise additional funds sooner than we presently anticipate. Moreover, research and development and our operating costs and fixed expenses such as rent and other contractual commitments, including those for our research collaborations, are substantial and are expected to increase in the future.

Unless and until we can generate a sufficient amount of revenue, we may finance future cash needs through public or private equity offerings, license agreements, debt financings, collaborations, strategic alliances or marketing and/or distribution arrangements. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms, or at all.

To the extent that we raise additional capital through the sale of equity or equity-linked securities (including warrants), convertible debt, our shelf registration statements, or other offerings, or if any of our current debt is converted into equity or if our existing warrants are exercised, your ownership interest will be diluted, and the liquidation or other preferences may adversely affect your rights as a stockholder. If we incur additional indebtedness, our fixed payment obligations will increase, and we may have to comply with certain restrictive covenants that are similar to those associated with the revenue interest liability, such as limitations on our ability to incur additional debt, limitations on our ability to acquire or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we raise additional funds through strategic partnerships and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or product candidates, or grant licenses on terms unfavorable to us, or exercise our Call Option (as defined in the RIPA) to purchase the outstanding revenue interest liability, which will require us to generate a significant amount of cash flow to offset these outflows. We have no committed source of additional capital, and if we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may be required to delay or reduce the scope of or eliminate one or more of our research or development programs or our commercialization efforts. See “—Our payment obligations under the RIPA may adversely affect our financial position and results of operations and our ability to raise additional capital, which in turn may increase our vulnerability to adverse regulatory developments or economic or business downturns”and Note11“Revenue InterestPurchase Agreement” of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for more information. Our current license and collaboration agreements may also be terminated if we are unable to meet the payment obligations under those agreements. As a result, we may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.

Our payment obligations under the RIPA may adversely affect our financial position and results of operations and our ability to raise additional capital, which in turn may increase our vulnerability to adverse regulatory developments or economic or business downturns.

On December 29, 2023, we entered into the RIPA with Infinity and Oberland. Pursuant to the RIPA, Oberland acquired certain Revenue Interests from us for a gross purchase price of $200.0 million paid on closing, less certain transaction expenses. In addition, on May 13, 2024, Oberland purchased additional Revenue Interests from us in exchange for a $100.0 million Second Payment, which we requested upon satisfaction of certain conditions specified in the RIPA, including the receipt of approval from the FDA of our BLA for ANKTIVA with BCG for the treatment of adult patients with BCG-unresponsive NMIBC with CIS with or without papillary tumors on or before June 30, 2024. In consideration for the aforementioned payments, Oberland has the right

Table of Contents

to receive quarterly Revenue Interest Payments from us based on, among other things, our worldwide net sales, excluding those in China, which are tiered payments ranging from 4.50% to 10.00%, subject to increase or decrease, following December 31, 2029 depending on whether the aggregate payments made to Oberland as of that date met or exceeded the Cumulative Purchaser Payments (as defined in the RIPA). In addition, if the aggregate payments to Oberland as of December 31, 2029 do not equal or exceed the amount of the Cumulative Purchaser Payments, then we are obligated to make a one-time payment to Oberland in an amount equal to 100% of the Cumulative Purchaser Payments, less the aggregate amount of our previous payments to Oberland as of December 31, 2029 (the True-Up Payment, as defined in the RIPA). See Note 11“Revenue Interest Purchase Agreement” of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for more information.

The RIPA and our payment obligations to Oberland could have important negative consequences to holders of our securities. For example, a portion of our cash flow from operations will be needed to make required payments to Oberland and will not be available to fund future operations.

Payment requirements under the RIPA will increase our cash outflows. Our future operating performance is subject to market conditions and business factors that are beyond our control. If our cash inflows and capital resources are insufficient to allow us to make required payments, we may have to reduce or delay capital expenditures, sell assets or seek additional capital. If we raise funds by selling additional equity, such sales will result in dilution to our stockholders. There is no assurance that if we are required to secure funding, we can do so on terms acceptable to us, or at all. Failure to pay amounts owed to Oberland when due would result in a default under the RIPA and could result in foreclosure on all or substantially all of our assets, which would have a material adverse effect.

The RIPA contains affirmative and negative operational covenants and events of default, which may prevent us from capitalizing on business opportunities and taking some corporate actions and give rise to a Put Option in favor of Oberland, which could have a material adverse effect on our financial condition and business operations.

The RIPA contains affirmative and negative covenants and events of default, including covenants and restrictions that, among other things, restrict our ability to incur liens, incur additional indebtedness, make loans and investments, enter into transactions with affiliates, engage in mergers and acquisitions, engage in asset sales and exclusive licensing arrangements, and declare dividends to our stockholders, in each case, subject to certain exceptions set forth in the RIPA. Additionally, Oberland has a Put Option enabling them to terminate the RIPA and to require the company to repurchase the Revenue Interests upon enumerated events such as a bankruptcy event, failure to make a payment, an uncured material breach, default on certain third-party agreements, a breach or default under any subordination agreements with respect to indebtedness to existing stockholders, any right to repurchase or accelerate debt instruments like permitted convertible notes, existing stockholder indebtedness, or subordinated notes during certain time periods, judgments in excess of certain amounts against us, a material adverse effect, the loss of regulatory approval of our approved product, or a change of control. The triggering of the Put Option, including by our failure to comply with these covenants, would permit Oberland to declare certain amounts to be immediately due and payable. If we were to default under the terms of the RIPA, including by failure to make such accelerated payments, Oberland could exercise remedies, including initiating foreclosure proceedings against all or substantially all of our assets. Oberland’s right to repayment is senior to the rights of the holders of our common stock. Any triggering of the Put Option or other declaration by Oberland of an event of default under the RIPA could significantly harm our financial condition, business and prospects and could cause the price of our common stock to decline.

Our debt and revenue interest liability could adversely affect our cash flows and limit our flexibility to raise additional capital.

We have a significant amount of debt and a revenue interest liability and may need to incur additional debt to support our growth. As of December 31, 2024, our indebtedness was comprised of a $505.0 million convertible promissory note held by an entity affiliated with Dr. Soon-Shiong and a revenue interest liability with Oberland in excess of $300.0 million. The total amount paid to Oberland depends on when we repay this debt. See Note 11“Revenue Interest Purchase Agreement” of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for more information about the revenue interest liability.

Table of Contents

Our substantial amount of debt could have important consequences and could:

•require us to dedicate a substantial portion of our cash and cash equivalents to make interest and principal payments on our debt and revenue interest liability payments, reducing the availability of our cash and cash equivalents and cash flow from operations to fund future capital expenditures, working capital, execution of our strategy and other general corporate requirements;

•increase our cost of borrowing and even limit our ability to access additional debt to fund future growth;

•increase our vulnerability to general adverse economic and industry conditions and adverse changes in governmental regulations;

•limit our flexibility in planning for, or reacting to, changes in our business and industry, which may place us at a disadvantage compared with our competitors; and

•limit our ability to borrow additional funds, even when necessary to maintain adequate liquidity, which would also limit our ability to further expand our business.

The occurrence of any of the foregoing factors could have a material adverse effect on our business, results of operations and financial condition.

Further, the company’s ability to make scheduled payments of the principal of, potential Test Date payments of, to pay interest or royalties on, or to refinance any current or future indebtedness, including the related-party promissory note or the revenue interest liability, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate sufficient cash flows from operations in the future to service our indebtedness, pay the revenue interest liability, and make necessary capital expenditures. If we are unable to generate such cash flows, we may be required to adopt one or more alternatives, such as selling assets, restructuring indebtedness, including the revenue interest liability, or obtaining additional equity or equity-linked capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness, including the revenue interest liability, at maturity or otherwise, will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

There can be no assurance that we can refinance the related-party promissory note or revenue interest liability or what terms will be available in the market at the time of refinancing. Furthermore, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to the refinancing would increase. These risks could materially adversely affect our financial condition, cash flows and results of operations.

The value of our warrants outstanding and the revenue interest liability are subject to potentially material increases and decreases based on fluctuations in the price of our common stock or projected sales and the probability of specific events, which may affect our results of operations and financial position and could adversely affect our stock price.

In connection with our RDO during the year ended December 31, 2023, we entered into warrant agreements with certain institutional investors that allow such investors to purchase up to an aggregate total of 28,641,911 shares of our common stock at an exercise price of $3.2946 per share. As of December 31, 2024, 6,399,171 warrants were exercisable with an expiration date of July 24, 2026.

We account for the warrants as derivative instruments, and changes in the fair value of the warrants are included in other income (expense), net, on the consolidated statement of operations for each reporting period. As of December 31, 2024, the fair value of warrant liabilities included in the consolidated balance sheet was $8.6 million. We use the Black-Scholes option pricing model to determine the fair value of the warrants. As a result, the valuation of these derivative instruments is subjective, and the Black-Scholes option pricing model requires the input of subjective assumptions, including the expected stock price volatility and probability of a fundamental transaction (a strategic merger or sale). Changes in these assumptions can materially affect the fair value estimate. We could, at any point in time, ultimately incur amounts different than the carrying value, which could have a significant impact on our results of operations and financial position.

Table of Contents

We account for the revenue interest liability as a liability, net of a debt discount comprised of deferred issuance costs, the fair value of a freestanding option agreement related to the SPOA, and the fair value of embedded derivatives requiring bifurcation on the consolidated balance sheet. The company imputes interest expense associated with this liability using the effective interest rate method. The effective interest rate is calculated based on the rate that would enable the debt to be repaid in full over the anticipated life of the arrangement. Interest expense is recognized over the estimated term on the consolidated statement of operations. The interest rate on the liability and the underlying value of the bifurcated embedded derivative may vary during the term of the agreement depending on a number of factors, including the level of actual and forecasted net sales, and in the case of the derivative, specific probabilities associated with RIPA Put/Call events or Test Date payments underlying our Monte Carlo analysis. The company evaluates the interest rate quarterly based on actual and forecasted net sales utilizing the prospective method. A significant increase or decrease in actual or forecasted net sales will materially impact the revenue interest liability and/or the bifurcated embedded derivative, interest expense, and the time period for repayment.

Fluctuations in warrant, revenue interest liability, and derivative values, and changes in the assumptions and factors used in the model may impact our operating results, making it difficult to forecast our operating results and making period-to-period comparisons less predictive of future performance. In one or more future quarters, our results of operations may fall below the expectations of securities analysts and investors. In that event, the market price of our common stock could decline. In addition, the market price of our common stock may fluctuate or decline regardless of our operating performance.

The accounting method for convertible debt securities could have a material effect on our reported financial results.

We entered into a second amended and restated promissory note with Nant Capital on December 10, 2024 in connection with an equity offering. Pursuant to the terms of the second amended and restated promissory note, Tranche 1 of the prior promissory note (the December 2023 Promissory Note) with a principal amount of $125.0 million and Tranche 2 of the December 2023 Promissory Note with a principal amount of $380.0 million were combined into one convertible promissory note with a principal amount of $505.0 million (the December 2024 Promissory Note).

The December 2024 Promissory Note was accounted for as part of a debt extinguishment, in accordance with FASB ASC Topic 470-50, Debt – Modifications and Extinguishments (ASC 470-50), as the amendment was substantially different than the terms of the promissory notes prior to the amendment. The company elected the fair value option of accounting under FASB ASC Topic 825, Financial Instruments (ASC 825), for the December 2024 Promissory Note. As a result of the fair value option election, the December 2024 Promissory Note and the embedded derivative were accounted for as a single instrument in accordance with FASB ASC Topic 815, Derivatives and Hedging (ASC 815). Changes in fair value of the December 2024 Promissory Note are recorded as a component of other income (expense), net, on the consolidated statement of operations. There is no current observable market for the December 2024 Promissory Note and, as such, we determined the fair value by using the binomial lattice model with significant unobservable inputs including an expected market yield, an expected volatility, and a risk-free rate. The changes in fair value of the December 2024 Promissory Note may have a substantial effect and may have a negative impact on our statement of financial position and statement of operations. It is difficult to predict the effect on our future financial results as the significant inputs are outside of our control.

We invest our cash on hand in various financial instruments which are subject to risks that could adversely affect our business, results of operations, liquidity and financial condition.

We have typically invested our cash in a variety of financial instruments, including investment-grade short- to intermediate-term corporate debt securities, government-sponsored securities and European bonds; however, after our entry into the RIPA, we can no longer invest our excess funds in corporate or European bonds. Certain of our investments are subject to credit, liquidity, market, and interest rate risk. Such risks, including the failure or severe financial distress of the financial institutions that hold our cash and cash equivalents, and investments, may result in a loss of liquidity, impairment to our investments, realization of substantial future losses, or a complete loss of the investments in the long-term, which may have a material adverse effect on our business, results of operations, liquidity and financial condition. To manage the risk to our investments, we maintain an investment policy that, among other things, limits the amount that we may invest in any one issue or any single issuer and requires us to only invest in high credit quality securities to preserve liquidity.

Our ability to use NOLs and research and development credits to offset future taxable income may be subject to certain limitations.

In general, under Sections 382 and 383 of the Code, a corporation that undergoes an ownership change is subject to limitations on its ability to utilize its pre-change NOLs or credits, to offset future taxable income or taxes. For these purposes, an ownership change generally occurs when the aggregate stock ownership of one or more stockholders or groups of stockholders who own at least 5% of a corporation’s stock increases its ownership by more than 50 percentage points over its lowest ownership percentage within a specified testing period (“ownership shift”). We have not conducted a complete study to assess whether a change of control has occurred or whether there have been multiple changes of control since inception due to the significant complexity and cost associated with such a study. If we have experienced a change of control, as defined by Section 382, at any time since inception (including as a result of the March 2021 merger which pursuant to which NantKwest and NantCell combined their businesses), utilization of the NOL carryforwards or research and development tax credit carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the NOL carryforwards or research and development tax credit carryforwards before utilization. In addition, our NOLs or credits may also be impaired under state law. Accordingly, we may not be able to utilize a material portion of our NOLs or credits.

Since we will need to raise substantial additional funding to finance our operations, we may experience further ownership shifts in the future, some of which may be outside of our control. Limits on our ability to use our pre-change NOLs or credits to offset U.S. federal taxable income could potentially result in increased future tax liability to us if we earn net taxable income in the future. In addition, under the legislation commonly referred to as the TCJA, as modified by the Coronavirus Aid, Relief, and Economic Security Act, the amount of NOLs generated in taxable periods beginning after December 31, 2017, that we are permitted to deduct in any taxable year beginning after December 31, 2020 is limited to 80% of our taxable income in such year, where taxable income is determined without regard to the NOL deduction itself. The TCJA allows post-2017 unused NOLs to be carried forward indefinitely. Similar rules apply under state tax laws. In addition, some states, e.g., California, may suspend the use of NOL carryovers that may result in state taxable income and liabilities.

Our transfer pricing policies may be subject to challenge by the IRS or other taxing authorities.

Our intercompany relationships are subject to complex transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant tax authorities may disagree with our determinations as to the value of assets sold or acquired or income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and our position were not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows, and lower overall profitability of our operations. We believe that our consolidated financial statements reflect adequate reserves to cover such a contingency, but there can be no assurances in that regard.

Unanticipated changes in effective tax rates or adverse outcomes resulting from new tax statutes or regulations, examination of our income or other tax returns could expose us to greater than anticipated tax liabilities.

The tax laws applicable to our business, including the laws of the U.S. and other jurisdictions, are subject to change, interpretation and certain jurisdictions may aggressively interpret their laws to raise additional tax revenue. It is possible that tax authorities may disagree with certain positions we have taken, are currently taking or will take, and any adverse outcome of such a review or audit could have a negative effect on our financial position and results of operations. Further, the determination of our provision for income taxes and other tax liabilities requires significant judgment by management, and there are transactions where the ultimate tax determination is uncertain. Although we believe that our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded on the consolidated financial statements and may materially affect our financial results in the period or periods for which such determination is made.

In addition, tax laws are dynamic and subject to change as new laws are passed and new interpretations of the law are issued or applied. For example, in August 2022, the U.S. enacted the IRA, which imposes a 15% minimum tax on the adjusted financial statement income of certain large corporations, as well as a 1% percent excise tax on corporate stock repurchases by publicly traded companies. Additionally, for taxable years beginning on or after January 1, 2022, the Code eliminated the right to deduct research and development expenditures currently and requires taxpayers to capitalize and amortize U.S. and foreign research and development expenditures over 5 and 15 tax years, respectively. These updates, as well as any other changes to tax laws that are enacted, could adversely affect our tax liability.

Risks Related to the Discovery, Development and Commercialization of our Approved Product and our Other Product Candidates

We are substantially dependent on the successful commercialization of our approved product and the success and regulatory approval of our other product candidates. If we are unable to successfully commercialize our approved product or successfully complete clinical development of, obtain regulatory approval for, or commercialize, our other product candidates, or if we experience delays in doing so, our business will be materially harmed.

Prior to the approval of ANKTIVA with BCG for the treatment of adult patients with BCG-unresponsive NMIBC with CIS with or without papillary tumors for commercial sale, we primarily generated revenues from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables, and grant programs. The company expects to continue to generate revenue from these programs.

Until April 2024, we had no clinical products approved for commercial sale and thus had not generated any revenue from therapeutic and vaccine product candidates that are or were under development. In addition, now that we have received FDA approval for ANKTIVA with BCG for the treatment of adult patients with BCG-unresponsive NMIBC with CIS with or without papillary tumors, we have begun to generate revenue although we expect it to take some time to generate significant revenue from our approved product and we can provide no assurance when, or if, this will occur. We began commercial distribution of our approved product in May 2024; however, we can provide no assurance with respect to our future revenues, both in terms of amounts and pace, market acceptance, reimbursement from third-party payors, or the profitability of our approved product or any other product candidate for which we may obtain approval. We are required to comply with certain post-marketing commitments, including completion of our QUILT 3032 clinical trial and annual reporting for up to four years, with a final report submission to FDA by the end of 2029. Our business currently depends heavily on our ability to successfully commercialize our approved product in the U.S. and in other jurisdictions where we may obtain marketing approval. We may never be able to successfully commercialize our approved product or meet our, or analysts or other third parties’ expectations with respect to revenues. We have never marketed, sold, or distributed for commercial use any pharmaceutical product other than our approved product, with respect to which we recently began efforts to initiate commercial sales. There is no guarantee that the infrastructure, systems, processes, policies, relationships, and materials we have built for the launch and commercialization of our approved product in the U.S. or elsewhere will be sufficient for us to achieve success at the levels we expect.

We may encounter issues and challenges in commercializing our approved product and generating substantial revenues. We may also encounter challenges related to reimbursement of our approved product, including potential limitations in the scope, breadth, availability, or amount of reimbursement covering our approved product. Similarly, healthcare settings or patients may determine that the financial burdens of treatment are not acceptable and as a result physicians may be reluctant to recommend our approved product to their patients. We may face other limitations or issues related to the price of our approved product. Our results may also be negatively impacted if we have not adequately sized our field teams, or our physician segmentation and targeting strategy is inadequate or if we encounter deficiencies or inefficiencies in our infrastructure or processes. Other factors that may hinder our ability to successfully commercialize approved product, or any of our other product candidates if or when approved and generate substantial revenues, include:

•the acceptance of our approved product by patients and the medical community, including industry groups and third-party payors;

•the ability of our third-party manufacturer(s) to manufacture commercial supplies of our approved product at acceptable costs, to remain in good standing with regulatory agencies, and to maintain commercially viable manufacturing processes that are, to the extent required, compliant with cGMP regulations;

•our ability to remain compliant with laws and regulations that apply to us and our commercial activities;

•FDA-mandated package-insert requirements and successful completion of FDA post-marketing requirements;

•the actual market size for our approved product, which may be different than expected;

•the length of time that patients who are prescribed our drug remain on treatment;

•our ability to obtain marketing approval for our approved product outside of the U.S.;

•the sufficiency of our drug supply to meet commercial and clinical demands, which could be negatively impacted if our projections regarding the potential number of patients are inaccurate, we are subject to unanticipated regulatory requirements, or our current drug supply is destroyed, or negatively impacted at our manufacturing sites, storage sites, or in transit;

•the availability of reimbursement for our approved product and physicians’ understanding regarding the same;

•our ability to effectively compete with other therapies that may emerge for the treatment of bladder cancer; and

•our ability to maintain, enforce, and defend third party challenges to our intellectual property rights in and to our approved product or any of our other product candidates.

Any of these issues could impair our ability to successfully commercialize our approved product or to generate substantial revenues or profits or to meet our expectations with respect to the amount or timing of revenues or profits. Any issues or hurdles related to our commercialization efforts may materially adversely affect our business, results of operations, financial condition, and prospects. There is no guarantee that we will be successful in our launch or commercialization efforts with respect to our approved product. We may also experience significant fluctuations in sales of our approved product from period to period and, ultimately, we may never generate sufficient revenues from our approved product to reach or maintain profitability or sustain our anticipated levels of operations. Any inability on our part to successfully commercialize our approved product in the U.S., and any other international markets where it may subsequently be approved, or any significant delay, could have a material adverse impact on our ability to execute upon our business strategy.

In addition, while we are pursuing and anticipating certain additional regulatory submissions in 2025 following discussions with the FDA, such as a potential supplemental BLA submission for BCG-unresponsive NMIBC patients in the papillary indication, a BLA for second-line and third-line treatment of patients with NSCLC who are progressing on CPIs, and a potential BLA for the indication of reversal of lymphopenia in patients receiving standard-of-care chemotherapy and/or radiation and for the treatment of locally advanced or metastatic pancreatic cancer, among others, the regulatory review process is dynamic and highly uncertain. Even if we are able to prepare and submit these regulatory submissions on the anticipated timeline, there can be no assurance that the FDA will accept the BLAs and other regulatory submissions for filing and review, and there can be no assurance that the FDA will ultimately approve such BLAs and submissions if accepted for filing and review.

Further, we have invested a significant portion of our efforts and financial resources in the development of ANKTIVA, our novel antibody-cytokine fusion protein, and our other product candidates, second-generation hAd5 vaccine candidates, and our NK cell therapy candidates. Our other product candidates will require additional clinical and non-clinical development, regulatory approval, commercial manufacturing arrangements, enhancement of our commercial organization and service providers, significant marketing efforts, and further investment before we can generate any revenue from the sale of these other potential products. We expect to invest heavily in our other current product candidates and in any future product candidates that we may develop. Our product candidates are susceptible to the risks of failure inherent at any stage of product development, including the appearance of unexpected adverse events or failure to achieve primary endpoints in clinical trials. Furthermore, we cannot assure you that we will meet our timelines for current or future clinical trials, including post-market study requirements for our approved product, which may be delayed or not completed for a number of reasons. Additionally, our ability to generate revenues from our approved product and any other combination therapy products will depend on the availability of the other therapies used in combination therewith, including BCG, with which our approved product and other product candidates are intended to be used. In particular, there has been a shortage of TICE BCG in the U.S. According to the American Urological Association, Merck is the sole manufacturer and supplier of TICE BCG in the U.S. and many other countries around the world. Increasing demand for BCG has led to supply constraints for TICE BCG, which could materially impact the demand for our approved product and our ability to commercialize our approved product, and our efforts to introduce an alternative source of BCG in connection with our collaboration with the Serum Institute may not be successful.

We have limited experience as a commercial company and the sales, marketing, and distribution of our approved product or any future approved products may be unsuccessful or less successful than anticipated.

We recently began commercializing our approved product in the U.S. As a company, we have no prior experience commercializing a product. The success of our commercialization efforts for our approved product and any future approved products is difficult to predict and subject to the effective execution of our business plan, including, among other things, the continued development of our internal and external sales, marketing, and distribution capabilities and our ability to navigate the significant expenses and risks involved with the development and management of such capabilities.

Table of Contents

For example, we have hired and contracted for service providers in areas to support commercialization, including in sales management, sales representatives, marketing, access and reimbursement, sales support, and distribution. There are significant expenses and risks involved with establishing our sales, marketing, and distribution capabilities, including our ability to hire or contract, retain, and appropriately incentivize qualified individuals, provide adequate training to sales and marketing personnel, and effectively manage geographically dispersed sales and marketing teams to generate sufficient demand. Any failure or delay in the development of these capabilities could delay or negatively affect the success of our commercialization efforts and our business. For example, the commercialization of our approved product may not develop as planned or anticipated, which may require us to, among others, adjust or amend our business plan and incur significant expenses.

Further, given our lack of experience commercializing products, we do not have a track record of successfully executing on the commercialization of an approved product. If we are unsuccessful in accomplishing our objectives and executing on our business plan, or if the commercialization of our approved product does not develop as quickly as planned, or any future approved products does not develop as planned, we may require significant additional capital and financial resources, we may not become profitable, and we may not be able to compete against more established companies in our industry.

We have developed an approved product and are developing other product candidates in combination with other therapies, which expose us to additional risks.

We have developed an approved product and are developing other product candidates in combination with one or more other therapies. We are studying ANKTIVA therapy along with other products and product candidates, such as BCG, CPIs, hAd5 TAAs, PD-L1 t-haNK, and M-ceNK. Since we have developed a product, or if we choose to develop other products for use in combination with an approved therapy, we are subject to the risk that the FDA, EMA or comparable foreign regulatory authorities in other jurisdictions could revoke approval of, or that safety, efficacy, manufacturing or supply issues could arise with the therapy used in combination with our approved product or our other product candidates. In particular, supply chain issues or shortages of other products used in combination with our approved product or any other product candidates could impact our ability to obtain FDA regulatory approval, meet clinical trial timelines, and commercialize our approved product or other product candidates. The FDA may require us to use more complex clinical trial designs in order to evaluate the contribution of each product and product candidate to any observed effects. To the extent that we do not have rights to already approved products, this may require us to work with another company to satisfy such a requirement or increase our cost of development. It is possible that the results of these trials could show that any positive results are attributable to the already approved product. Following product approval, the FDA may require that products used in conjunction with each other be cross labeled for combined use. If the therapies we use in combination with our approved product or our other product candidates are replaced as the standard-of-care for the indications we choose for our approved product or any of our other product candidates, the FDA or comparable foreign regulatory authorities may require us to conduct additional clinical trials. The occurrence of any of these risks could result in our own products, if approved, being removed from the market or being less successful commercially.

In addition, unapproved therapies face the same risks described with respect to our product candidates currently in development and clinical trials, including the potential for serious adverse effects, delays in clinical trials and lack of FDA approval. If the FDA or comparable foreign regulatory authorities do not approve or revoke their approval of these other therapies, or if safety, efficacy, quality, manufacturing or supply issues arise with, the therapies we choose to evaluate in combination with any of our product candidates, we may be unable to obtain approval of or market such other combination therapies.

Our clinical trials may fail to adequately demonstrate the safety and efficacy of our product candidates, which would prevent or delay regulatory approval and commercialization of other product candidates.

Our research and development programs of our other non-FDA-approved product candidates are at various stages of development. The clinical trials of our product candidates as well as the manufacturing and marketing of our product candidates will be subject to extensive and rigorous review and regulation by numerous government authorities in the U.S. and in other countries where we intend to test and market our product candidates. Before obtaining regulatory approvals for the commercial sale of any of our other product candidates, we must demonstrate through lengthy, complex, and expensive preclinical testing and clinical trials that our product candidates are safe, pure, and potent for use in their target indications. Each product candidate must demonstrate an adequate risk vs. benefit profile in its intended patient population and for its intended use. The risk/benefit profile required for product licensure will vary depending on these factors and may include not only the ability to show tumor shrinkage, but also adequate duration of response, a delay in the progression of the disease, and/or improvement in survival. For example, response rates from the use of our product candidates or their contribution of effect may not be sufficient to obtain regulatory

Table of Contents

approval unless we can also show an adequate duration of response. The clinical trials for our product candidates under development may not be completed on schedule, and regulatory authorities may ultimately disagree with our chosen endpoints or may find that our studies or study results do not support product approval. The FDA or foreign regulatory authorities may not interpret the results as we do or accept the therapeutic effects as valid endpoints in clinical trials necessary for market approval, or they may find that our clinical trial design or conduct does not meet the applicable approval requirement, and more trials could be required before we submit our product candidates for approval. Success in early clinical trials does not ensure that large-scale clinical trials will be successful, nor does it predict final results. Product candidates in later stages of clinical trials may fail to show the desired safety, tolerability, and efficacy traits despite having progressed through preclinical studies and initial clinical trials and after reviewing test results, we or our collaborators may abandon projects that we might previously have believed to be promising.

In addition, we do not have data on possible harmful long-term effects of our product candidates and do not expect to have this data in the near future. As a result, our ability to generate clinical safety and effectiveness data sufficient to support submission of a marketing application or commercialization of our product candidates is uncertain and is subject to significant risk.

The ongoing shortage of TICE BCG in the U.S. may adversely impact market uptake of ANKTIVA and it may also delay our ability to execute our clinical trials or seek new approvals.

There is an ongoing shortage of TICE BCG in the U.S., which may adversely impact market uptake of our approved product. The TICE BCG shortage may impact the number of patients who are treated with BCG for NMIBC with CIS with or without papillary tumors, therefore limiting the pool of BCG-unresponsive patients who may be candidates for our approved product. In addition, the TICE BCG shortage may also constrain the number of patients we can treat with our approved product since our product is administered along with BCG. In addition, we are currently enrolling patients in our Phase 2b blinded, randomized, two-cohort, open-label, multi-center trial of intravesical BCG with ANKTIVA vs. BCG alone, in BCG-naïve patients with high-grade NMIBC with CIS (Cohort A) and NMIBC papillary (Cohort B), which is impacted by the availability of TICE BCG. If we do not complete new trials timely, our ability to generate clinical safety and effectiveness data sufficient to support submission of a marketing application or commercialization of our product candidates in new indications could harm our business, operating results, prospects or financial condition. In addition, our efforts to introduce an alternative source of BCG in connection with our collaboration with Serum Institute (including a recent EAP approved by the FDA) and ultimately obtain regulatory approval for such alternative BCG supply may not be successful in mitigating the TICE BCG shortage, or at all.

We may choose to expend our limited resources on programs that do not yield successful product candidates or additional indications and may fail to capitalize on other indications and product candidates that may ultimately have been more profitable or had a greater likelihood of success.

We do not have sufficient resources to pursue development of all or even a substantial portion of the potential opportunities that we believe will be afforded to us by our product candidates. Because we have limited resources and access to capital to fund our operations, our management must make strategic decisions as to which product candidates and indications to pursue and how much of our resources to allocate to each. Our management must also evaluate the benefits of developing in‐licensed or jointly owned technologies, which in some circumstances we may be contractually obligated to pursue, relative to developing other product candidates, indications or programs. Our management has broad discretion to suspend, scale down, or discontinue any or all of these development efforts, or to initiate new programs to treat other diseases. If we select and commit resources to opportunities that we are unable to successfully develop, or we forego more promising opportunities, our business, financial condition, and results of operations will be adversely affected.

Our projections regarding the market opportunities for our approved product and our other product candidates may not be accurate, and the actual market for our approved product and other product candidates may be smaller than we estimate.

Since our approved product, current product candidates, and any future product candidates represent novel approaches to treating various conditions, it may be difficult to accurately estimate the potential revenues from our approved product and these other product candidates. Accordingly, we may spend significant capital trying to successfully commercialize our approved product or obtain approval for our other product candidates that have an uncertain commercial market. Our projections of addressable patient populations that may benefit from treatment with our approved product or other product candidates are based

Table of Contents

on our beliefs and estimates of the therapeutic benefit and adverse event profile of our approved product and other product candidates. These estimates, which have been derived from a variety of sources, including scientific literature, preclinical and clinical studies, surveys of clinics, patient foundations, or market research by third parties, may prove to be incorrect. Further, new studies or approvals of new therapeutics may change the estimated incidence or prevalence of these diseases. The number of patients may turn out to be lower than expected. Additionally, the potentially addressable patient population for our approved product or other product candidates may be limited or may not be amenable to treatment with our approved product or other product candidates and may also be limited by the cost of our treatments and the reimbursement of those treatment costs by third-party payors. Even if we obtain significant market share for our approved product or other product candidates, because the potential target populations may be small, we may never achieve profitability without obtaining regulatory approval for additional indications.

There can be no assurance that we will complete a strategic partnership transaction on acceptable terms, or at all.

We continue to explore potential global strategic partnership transactions for commercialization of ANKTIVA for certain indications. Factors that may impact our ability, or decision, to enter into such a strategic partnership, include, without limitation, the put/call features of the RIPA that may be triggered by entry into a strategic partnership depending on its scope and terms, and ultimately there can be no assurance that we will complete a transaction on acceptable terms, or at all. If we do not execute a strategic partnership transaction in the near term, it would eliminate a potential source of near-term funding, and may impact our ability to raise additional funds to meet our business needs. In addition, there are significant risks involved with building and managing a commercial infrastructure on a stand-alone basis, which could materialize in the event we do not execute a strategic partnership transaction or depending on the geographic scope of any executed transaction.

Interim, initial, top-line and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose preliminary, interim, or top-line data from our preclinical studies and clinical trials, which are based on preliminary analyses of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available or as patients from our clinical trials continue other treatments for their disease, or as inclusion and exclusion criteria is discussed with regulators. We also may make assumptions, estimations, calculations, and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the interim, top-line, or preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data has been received and fully evaluated. Top-line data also remains subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, top-line data should be viewed with caution until the final data are available. Adverse differences between preliminary or interim data and final data could significantly harm our business prospects. Further, disclosure of interim data by us or by our competitors could result in volatility in the price of our common stock.

In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is typically selected from a more extensive amount of available information, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure. If the interim, top-line, or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Our clinical trials may not be initiated or completed when we expect, or at all, may take longer and cost more to complete than we project, and may have higher costs than for more conventional therapeutic technologies or drug products. We may be required to conduct additional clinical trials or modify current or future clinical trials based on feedback we receive from the FDA.

We cannot guarantee that any current or future clinical trials will be conducted as planned or completed on schedule, if at all, or that any of our other product candidates will receive regulatory approval. A failure of one or more clinical trials can occur at any stage of the clinical trial process, other events may cause us to stop a clinical trial temporarily or permanently, and our future clinical trials may not be successful.

Table of Contents

Because our current product candidates include, and we expect our future product candidates to include, candidates based on advanced therapy technologies, we expect that they will require extensive research and development and have substantial manufacturing costs. In addition, costs to treat patients and to treat potential side effects that may result from our product candidates can be significant. Some clinical trial sites may not bill, or obtain coverage from Medicare, Medicaid, or other third-party payors for some or all of these costs for patients enrolled in our clinical trials, and clinical trial sites outside of the U.S. may not reimburse for costs typically covered by third-party payors in the U.S. As a result, we may be required by those trial sites to pay such costs. Accordingly, our clinical trial costs are likely to be significantly higher per patient than those of more conventional therapeutic technologies or drug products.

Collaborations with other entities may be subject to additional delays because of the management of the trials, contract negotiations, the need to obtain agreement from multiple parties, and the necessity of obtaining additional approvals for therapeutics used in the combination trials. These combination therapies will require additional testing, and clinical trials will require additional FDA approval and will increase our future costs.

Any inability to successfully complete preclinical and clinical development could result in additional costs to us, slow down our product development and approval process, or impair our ability to commence product sales and generate revenues. In addition, if we make manufacturing changes to our approved product or other product candidates, we may be required to, or we may elect to, conduct additional trials to bridge our modified approved product or other product candidates to earlier versions. These changes may require FDA approval or notification and may not have their desired effect. The FDA may also not accept data from prior versions of the product to support an application, delaying our clinical trials or programs or necessitating additional clinical trials or preclinical studies. We may find that this change has unintended consequences that necessitate additional development and manufacturing work, additional clinical and preclinical studies, or that results in refusal to file or non-approval of a BLA and/or NDA.

Clinical trial delays could shorten any period during which our product candidates have patent protection and may allow our competitors to bring products to market before we do, which could impair our ability to successfully commercialize our product candidates and may harm our business and results of operations. In addition, we have in the past experienced clinical holds imposed upon certain of our or investigator-led clinical trials for various reasons, and we may experience further clinical trial holds in the future. If we fail to commence or complete, or experience delays in, any of our planned clinical trials, our stock price and our ability to conduct our business as currently planned could be harmed.

If we are required by the FDA or any equivalent foreign regulatory authority to perform clinical trials or studies in addition to those we currently expect to conduct, or if there are any delays in completing the clinical trials of our other product candidates, our expenses could increase substantially. On April 22, 2024, the FDA approved our product, ANKTIVA with BCG for the treatment of adult patients with BCG-unresponsive NMIBC with CIS with or without papillary tumors. We are required to comply with certain post-marketing commitments, including completion of our QUILT 3032 clinical trial and annual reporting for up to four years, with a final report submission to the FDA by the end of 2029.

Even if more of our product candidates are approved and commercialized, we still may not become profitable.

If approved for marketing by applicable regulatory authorities, our ability to generate revenues from our other product candidates will depend on our ability to:

•price our other product candidates competitively such that third-party and government reimbursement leads to broad product adoption;

•prepare a broad network of clinical sites for administration of our other product candidates;

•create market demand for our other product candidates through our own or our partner’s marketing and sales activities, and any other arrangements to promote these product candidates that we may otherwise establish;

•receive regulatory approval for the targeted patient population(s) and claims that are necessary or desirable for successful marketing;

•manufacture our other product candidates through third-party CMOs or in our own manufacturing facilities or facilities owned by entities affiliated with Dr. Soon-Shiong in sufficient quantities and at acceptable quality and manufacturing cost to meet regulatory requirements and commercial demand at launch and thereafter;

Table of Contents

•establish and maintain agreements with wholesalers, distributors, pharmacies, and group purchasing organizations on commercially reasonable terms;

•obtain, maintain, protect, and enforce patent and other intellectual property protection and regulatory exclusivity for our other product candidates;

•successfully commercialize any of our other product candidates that receive regulatory approval;

•maintain compliance with applicable laws, regulations, and guidance specific to commercialization including interactions with health care professionals, patient advocacy groups, and communication of health care economic information to payors and formularies;

•achieve market acceptance of our other product candidates by patients, the medical community, and third-party payors;

•achieve appropriate reimbursement for our product candidates;

•maintain a distribution and logistics network capable of product storage within our specifications and regulatory guidelines, and further capable of timely product delivery to commercial clinical sites;

•effectively compete with other therapies or competitors; and

•following launch, ensure that our approved product will be used as directed and that additional unexpected safety risks will not arise.

We can provide no assurance with respect to the profitability or the market share that we might achieve for our product candidates, if approved. The target patient population for which we obtain approval may be narrower than we expect. Additionally, we may not be able to obtain the labeling claims necessary or desirable for the promotion of our approved product. Further, supply chain issues or shortages associated with combination products that may be used with our approved product, such as ANKTIVA plus BCG, may limit the demand for our approved product.

We are also party to agreements that may require substantial payments upon the occurrence of certain milestones. As an example, in connection with our 2017 acquisition of Altor, we issued CVRs under which we agreed to pay the prior stockholders of Altor approximately $304.0 million of contingent consideration upon calendar-year worldwide net sales of ANKTIVA exceeding $1.0 billion prior to December 31, 2026 with amounts payable in cash or shares of our common stock or a combination thereof. As of December 31, 2024, Dr. Soon-Shiong and his related party hold approximately $139.8 million of net sales CVRs, and they have both irrevocably agreed to receive shares of the company’s common stock in satisfaction of their CVRs. We may be required to pay the other prior Altor stockholders up to $164.2 million for their net sales CVRs should they choose to have their CVRs paid in cash instead of common stock. If this were to occur, we may need to seek additional sources of capital, and any such financing activities may be restricted by the covenants included in the terms of the RIPA. As such, we may face difficulties raising additional capital and may have to accept unfavorable terms and as a result, we may not be able to achieve profitability or positive cash flow.

In connection with our financing in December 2023, we entered into the RIPA with Infinity and Oberland. Oberland has the right to receive quarterly Revenue Interest Payments from us based on, among other things, our worldwide net sales, excluding those in China, which are tiered payments ranging from 4.50% to 10.00%, subject to increase or decrease, following the Test Date depending on whether our aggregate payments made to Oberland as of the Test Date have met or exceeded the Cumulative Purchaser Payments. In addition, if our aggregate payments made as of the Test Date to Oberland do not equal or exceed the amount of the Cumulative Purchaser Payments as of such date, then we are obligated to make a one-time payment True-Up Payment as described above. In addition to other considerations of the RIPA and the associated impact to our profitability and cash flow, if we were required to make a True-Up Payment, we may need to seek additional sources of capital, and we may not be able to achieve profitability or positive cash flow.

Table of Contents

If we encounter delays or difficulties enrolling and/or maintaining patients in our clinical trials, our clinical development activities, and receipt of necessary marketing approvals, could be delayed or otherwise adversely affected.

The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until its conclusion. We may experience difficulties or delays in patient enrollment and retention in our clinical trials for a variety of reasons.

Because the number of qualified clinical investigators is limited, we may need to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites. In addition, in the past we have engaged, and we intend to continue to engage, in clinical trial efforts outside of the U.S., which gives rise to additional potential complexity and challenges, and further reliance upon third parties in foreign jurisdictions. Moreover, because our product candidates represent a departure from more commonly used methods for cancer and/or viral disease treatment, potential patients and their doctors may be inclined to use conventional therapies, such as chemotherapy and approved immunotherapies that have established safety and efficacy profiles, rather than enroll patients in any future clinical trial.

Delays or failures in planned patient enrollment or retention may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the development of our product candidates or could render further development impossible.

Our approved product and other product candidates may cause undesirable side effects, adverse events, or have other properties or safety risks that could halt their clinical development, delay or prevent their regulatory approval, result in regulatory warning letters, product recalls, regulatory and manufacturing holds, or limit their commercial potential or result in other significant negative consequences.

Results of our trials could reveal a high and unacceptable severity and prevalence of side effects, adverse events or unexpected characteristics. Combination immunotherapy that includes our current product candidates may be associated with more frequent adverse events or additional adverse events. Undesirable side effects or unacceptable toxicities caused by our other product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials or order our clinical trials to be placed on clinical hold, and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities for any or all targeted indications. The FDA or comparable foreign regulatory authorities may also require additional data, clinical trials, or preclinical studies should unacceptable toxicities arise. We may need to abandon development or limit development of that product candidate to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe, or more acceptable from a risk/benefit perspective. Even if we were to receive product approval, such approval could be contingent on inclusion of unfavorable information in our product labeling, such as limitations on the indicated uses for which the products may be marketed or distributed, a label with significant safety warnings, including boxed warnings, contraindications, and precautions, a label without statements necessary or desirable for successful commercialization, or requirements for costly post marketing testing and surveillance, or other requirements, including a REMS to monitor the safety or efficacy of the products, and in turn prevent us from commercializing and generating revenues from the sale of our current or future product candidates. In addition, these serious adverse effects may not be appropriately recognized or managed by the treating medical staff, as toxicities resulting from our other product candidates are not normally encountered in the general patient population and by medical personnel. They may have difficulty observing patients and treating toxicities, which may be more challenging due to personnel changes, shift changes, house staff coverage or related issues. This could lead to more severe or prolonged toxicities or even patient deaths, which could result in us or the FDA delaying, suspending or terminating one or more of our clinical trials and which could jeopardize regulatory approval. Any of these occurrences may materially harm our business, financial condition and prospects.

The manufacture of our approved product and other product candidates is complex, and we may encounter difficulties in production, particularly with respect to process development, quality control, cGMP compliance, or scaling-up of our manufacturing capabilities. If we or our related parties, or any of our third-party manufacturers, encounter such difficulties, our ability to gain approval, or to provide adequate supply of our product candidates for clinical trials or our products for patients, if approved, could be delayed or stopped, or we may be unable to maintain a commercially viable cost structure.

The manufacture of our approved product and other product candidates involves complex processes, especially for our biologics, vectors and cell therapy product candidates, which are complex, highly regulated and subject to multiple risks. As a result of the complexities, the cost to manufacture biologics, vectors, and cell therapies is generally higher than traditional small molecule chemical compounds, and the manufacturing process is less reliable and is more difficult to reproduce. The manufacture

Table of Contents

of fusion proteins, DNA and vaccine vectors, and cell therapy products require significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of cell therapy products often encounter difficulties in production, particularly in scaling up initial production. These problems include difficulties with production costs and yields, quality control, including stability of the product or other product candidates and quality assurance testing, shortages of qualified personnel, and compliance with strictly enforced federal, state, local, and foreign regulations. We may also find that the manufacture of our approved product or other product candidates is more difficult than anticipated, resulting in an inability to produce a sufficient amount of our other product candidates for our clinical trials or, if approved, commercial supply. Even minor deviations from normal manufacturing processes could result in reduced production yields, product defects, and other supply disruptions. Our approved product and other product candidates are manufactured using processes developed or modified by us, our affiliates, or by our third-party collaborators that we may not utilize for more advanced clinical trials or commercialization.

Currently we manufacture our approved product and other product candidates in our own manufacturing facilities, facilities owned by entities affiliated with Dr. Soon-Shiong and/or through third-party CMOs. Our clinical trials will need to be conducted with product candidates and materials that were produced under cGMP and/or GTP regulations, which are enforced by regulatory authorities. Our approved product and other product candidates may compete with other products and product candidates for access to manufacturing facilities. Moreover, because of the complexity and novelty of our manufacturing process, there are only a limited number of manufacturers that operate under cGMP regulations and that are both capable of manufacturing our approved product and other product candidates for us and willing to do so. If our third-party CMOs cease manufacturing for us, we would experience delays in obtaining sufficient quantities of our approved product for commercial supply and other product candidates for clinical trials and, if approved, commercial supply of such future products. Further, our third-party CMOs may breach, terminate, or not renew our agreements with them. If we were to need to find alternative manufacturing facilities or transfer between existing facilities it may take us significant time to find a replacement, if we are able to find a replacement at all and it would significantly impact our ability to develop, obtain regulatory approval for or market our approved product and/or other product candidates, if approved. The commercial terms of any new arrangement could be less favorable than our existing arrangements and the expenses relating to the transfer of necessary technology and processes could be significant.

We and our suppliers and third-party CMOs must maintain compliance with cGMP requirements and other applicable regulatory requirements. Any failure to comply with these regulations may require us to cease sales of our approved product or repeat clinical trials, which would delay the regulatory review process of our other product candidates. We may not be able to demonstrate sufficient comparability between products manufactured in different runs at the same or at different facilities to allow for inclusion of the clinical results from patients treated with products from these different runs, in our product registrations or to ensure a cGMP process to qualify our other product candidates.

We also are required to register certain clinical trials and post the results of certain completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within specified timeframes. Failure to do so could result in enforcement actions and adverse publicity.

Reliance on third-party manufacturers entails exposure to risks to which we would not be subject if we manufactured the product candidate ourselves, including:

•inability to negotiate manufacturing and quality agreements with third parties under commercially reasonable terms;

•reduced day-to-day control over the manufacturing process for our other product candidates as a result of using third-party manufacturers for all aspects of manufacturing activities;

•reduced control over the protection of our trade secrets, know-how, and other proprietary information from misappropriation or inadvertent disclosure or from being used in such a way as to expose us to potential litigation;

•termination or non-renewal of manufacturing agreements with third parties in a manner or at a time that may be costly or damaging to us or result in delays in the development or commercialization of our approved product or other product candidates; and

•disruptions to the operations of our third-party manufacturers or suppliers caused by conditions unrelated to our business or operations, including the bankruptcy or personnel turnover at the manufacturer or supplier.

Moreover, any problems or delays we or our third-party CMOs experience in preparing for commercial scale manufacturing of a product candidate may result in a delay in the FDA approval of the product candidate or may impair our ability to manufacture commercial quantities or such quantities at an acceptable cost, which could result in the delay, prevention, or impairment of clinical development and commercialization of our product candidates and could adversely affect our business. Furthermore, if we or our third-party CMOs fail to deliver the required commercial quantities of our product candidates on a timely basis and at reasonable costs, we would likely be unable to meet demand for our products and we would lose potential revenues. We may ultimately be unable to reduce the cost of goods for our other product candidates to levels that will allow for an attractive return on investment if and when those product candidates are commercialized.

In addition, the manufacturing process and facilities for our approved product and any other products that we may develop are subject to FDA and foreign regulatory authority approval processes, and we or our third-party CMOs will need to meet all applicable FDA and foreign regulatory authority requirements, including cGMP, on an ongoing basis. cGMP requirements include quality control, quality assurance and the maintenance of records and documentation. The FDA and other regulatory authorities enforce these requirements through facility inspections. Manufacturing facilities must submit to pre-approval inspections by the FDA that will be conducted after we submit our marketing applications, including BLAs and NDAs, to the FDA. Manufacturers are also subject to continuing FDA and other regulatory authority inspections following marketing approval. Further, we and our third-party CMOs must supply all necessary CMC documentation in support of a BLA or NDA on a timely basis. Our or our third-party CMOs’ manufacturing facilities may be unable to comply with our specifications, cGMP, and with other FDA, state, and foreign regulatory requirements, and there is no guarantee that we or our third-party CMOs will be able to successfully pass all aspects of a pre-approval or continued inspection by the FDA or other foreign regulatory authorities. For example, on May 9, 2023 the FDA delivered a CRL to us regarding the BLA filed in May 2022, indicating that the FDA had determined that it could not approve the original BLA submission in its initial form, and the FDA made recommendations to address the issues raised. The deficiencies in the CRL related to the FDA’s pre-license inspection of the company’s third-party CMOs, among other items. The CRL we received in response to our initial BLA submission required us to resubmit the BLA to the FDA addressing the issues in the CRL, resulting in additional expense and delay. On April 22, 2024, the FDA approved ANKTIVA with BCG for the treatment of adult patients with BCG-unresponsive NMIBC with CIS with or without papillary tumors.

Poor control of production processes can lead to the introduction of adventitious agents or other contaminants, or to inadvertent changes in the properties or stability of our product or other product candidates that may not be detectable in final product testing. If microbial, viral, environmental, or other contaminants are discovered in our product or other product candidates or in the manufacturing facilities in which our product or other product candidates are made, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination which could delay commercial sales and clinical trials and adversely harm our business. If we or our third-party CMOs are unable to reliably produce products to specifications acceptable to the FDA or other regulatory authorities, or in accordance with the strict regulatory requirements, we may not obtain or maintain the initial or continued approvals we need to commercialize such products. There is no assurance that either we or our third-party CMOs will be able to manufacture our approved product or any subsequently approved product candidate to specifications acceptable to the FDA or other regulatory authorities, to produce our product or other product candidates in sufficient quantities to meet the requirements for the launch of such products, or to meet potential future demand.

Deviations from manufacturing requirements may further require remedial measures that may be costly and/or time-consuming for us or a third party to implement and may include the temporary or permanent suspension of a clinical trial or commercial sales or the temporary or permanent closure of a facility. Any such remedial measures imposed upon us or third parties with whom we contract could materially harm our business.

As product candidates progress through preclinical and clinical trials to marketing approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize yield and manufacturing batch size, minimize costs and achieve consistent quality and results. Such changes carry the risk that they will not achieve these intended objectives. Any of these changes could cause our product or other product candidates to perform differently and affect our commercial sales or the results of planned clinical trials or other future clinical trials conducted with the altered materials. This could cause commercial sales to cease, delay completion of clinical trials, require the conduct of bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates, and jeopardize our ability to commercialize our other product candidates, if approved, and generate revenues.

Table of Contents

To the extent we use third-party CMOs, we are ultimately responsible for the manufacture of our products, once approved, and our other product candidates. A failure to comply with these requirements may result in regulatory enforcement actions against our manufacturers or us, including fines and civil and criminal penalties, which could result in imprisonment, suspension or restrictions of production, injunctions, delay or denial of product approval or supplements to approved products, clinical holds or termination of clinical trials, warning or untitled letters, regulatory authority communications warning the public about safety issues with the biologic, refusal to permit the import or export of the products, product seizure, detention, or recall, operating restrictions, suits under the federal civil FCA, corporate integrity agreements, consent decrees, or withdrawal of product approval.

Any of these challenges could cause us to cease commercial sales, delay completion of clinical trials, require bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidate, impair commercialization efforts, increase our cost of goods, and have a material adverse effect on our business, financial condition, results of operations and growth prospects.

We may not be successful in managing the buildout of our manufacturing facilities and associated costs or satisfying manufacturing-related regulatory requirements.

We have entered into facility leases for our planned manufacturing operations and related activities under which we are responsible for the buildout of the facility space and associated costs. The buildout of these facilities and related equipment purchases are complex and specialized and will involve substantial capital expenditures, and it could take longer, and cost more, than currently expected. Significant delays and/or cost overruns would result in higher expenditures and could be disruptive to operations, any of which could have a negative impact on our financial condition or results of operations. For example, during the first quarter of 2022 we acquired a leasehold interest in the 409,000 square foot Dunkirk Facility as described below. While we believe that governmental funding will assist in funding a small portion of the further buildout of the Dunkirk Facility, we will need to plan and fund most of the additional buildout of, and purchase additional equipment for, the Dunkirk Facility in connection with our planned full operations. In addition, it is possible that, once built, the leased facilities may prove to be less conducive to our operations than is currently anticipated, resulting in operational inefficiencies or similar difficulties that could prove difficult or impossible to remediate and result in an adverse impact on our financial condition or results of operations.

We also may not successfully realize the anticipated benefits from capital expenditures at such facilities based on factors such as delays and uncertainties regarding development, regulatory approval, and commercialization of our product candidates, as well as the potential to lose access to the leased facilities.

Further, in the future if we transition from our current third-party CMOs to our own manufacturing facilities, or to alternative third-party CMOs, for one or more of our products or other product candidates, including our approved product, we will need to conduct additional preclinical, analytical and/or clinical testing and obtain FDA approval before such manufacturing changes are implemented. If we are unsuccessful in demonstrating the comparability of supplies before and after a manufacturing change, such manufacturing change can result in a delay or disruption in our clinical development plan or our ability to commercialize any approved product. Any production shortfall that impairs the supply of our product or other product candidates could negatively impact our ability to sell our approved product, complete clinical trials, obtain regulatory approval, and commercialize our other product candidates. A product shortfall could have a material adverse effect on our business, financial condition and results of operations and adversely affect our ability to satisfy demand for our product or other product candidates, which could materially and adversely affect our revenue and results of operations.

In addition, our planned operations, including our development, testing, and future manufacturing activities, are subject to numerous environmental, health, and safety laws and regulations. These laws and regulations govern, among other things, the controlled use, handling, release, and disposal of and the maintenance of a registry for, hazardous materials and biological materials, such as chemical solvents, human cells, carcinogenic compounds, mutagenic compounds, and compounds that may have a toxic effect on reproduction, laboratory procedures and exposure to blood-borne pathogens. If we fail to comply with such laws and regulations, we could be subject to fines or other sanctions. Failure to successfully complete our buildouts and successfully operate our planned manufacturing facilities and satisfy manufacturing-related regulatory requirements could adversely affect the commercial viability of our product candidates and our business.

Cell-based therapies and biologics rely on the availability of reagents, specialized equipment, and other specialty materials, which may not be available to us on acceptable terms or at all. For some of these reagents, equipment, and materials, we rely or may rely on sole source vendors or a limited number of vendors, which could impair our ability to manufacture and supply our approved product and any future products, if approved.

We currently depend on a small number of suppliers for some of the materials used in, and processes required to develop, our approved product and other product candidates. For some of these reagents, equipment, and materials used in the manufacture of our approved product and other product candidates, we rely and may in the future rely on sole source vendors or a limited number of vendors. Some of these suppliers may not have the capacity to support commercial scale or clinical trials and commercial products manufactured under cGMP by biopharmaceutical firms or may otherwise be ill-equipped to support our needs. We also do not have supply contracts with many of these suppliers and may not be able to obtain supply contracts with them on acceptable terms or at all. Accordingly, we may experience delays in receiving key materials and equipment to support clinical or commercial manufacturing. An inability to continue to source product from any of these suppliers could adversely affect our ability to satisfy demand for our approved product and other product candidates, which could adversely and materially affect our product sales and operating results or our ability to conduct clinical trials, either of which could significantly harm our business.

As we seek to develop and scale our manufacturing process, we expect that we will need to obtain rights to and supplies of certain materials and equipment to be used as part of that process. We may not be able to obtain rights to such materials on commercially reasonable terms, or at all, and if we are unable to alter our process in a commercially viable manner to avoid the use of such materials or find a suitable substitute, it would have a material adverse effect on our business. Even if we are able to alter our process so as to use other materials or equipment, such a change may lead to a delay in our clinical development and/or commercialization plans. If such a change occurs for a product candidate that is already in clinical testing, the change may require us to perform both ex vivo comparability studies and to collect additional data from patients prior to undertaking more advanced clinical trials.

Because our approved product and other product candidates represent, and our other potential product candidates will represent, novel approaches to the treatment of disease, there are many uncertainties regarding the development, market acceptance, public opinion, third-party reimbursement coverage, and the commercial potential of our approved product and other product candidates, which may impact public perception of us and our approved product and other product candidates and which may adversely affect our ability to conduct our business and implement our business plans.

Human immunotherapy products are a new category of therapeutics. We use relatively novel technologies involving ANKTIVA, hAd5 and yeast constructs, and cell-based therapies, and our NK cell platform utilizes a relatively novel technology involving the genetic modification of human cells and utilization of those modified cells in other individuals. Because this is a relatively new and expanding area of novel therapeutic interventions, there are many uncertainties related to development, marketing, reimbursement, and the commercial potential for our approved product and other product candidates. There can be no assurance as to the length of the trial period, the number of patients the FDA will require to be enrolled in the trials in order to establish the safety, efficacy, purity and potency of immunotherapy products, or that the data generated in these trials will be acceptable to the FDA to support marketing approval. Adverse public attitudes may adversely impact our ability to enroll patients in clinical trials. The FDA may take longer than usual to come to a decision on any BLA and/or NDA that we submit and may ultimately determine that there is not enough data, information, or experience with our product candidates to support an approval decision. The FDA may also require that we conduct additional post-marketing studies or implement risk management programs, such as REMS, until more experience with our other product candidates is obtained. Finally, after increased usage, we may find that our product or other product candidates do not have the intended effect, do not work with other combination therapies or have unanticipated side effects, potentially jeopardizing initial or continuing regulatory approval and commercial prospects. More restrictive government regulations or negative public opinion could have an adverse effect on our business or financial condition and may delay or impair the commercialization of our approved product and development and commercialization of our product candidates or demand for our product or any products we may develop. Adverse events in our clinical trials, even if not ultimately attributable to our product candidates, and the resulting publicity could result in increased governmental regulation, unfavorable public perception, potential regulatory delays in the testing or approval of our potential product candidates, stricter labeling requirements for those product candidates that are approved and a decrease in demand for any such product candidates.

There is no assurance that the approaches offered by our approved product or other product candidates will gain broad acceptance among doctors or patients or that governmental agencies or third-party medical insurers will be willing to provide reimbursement coverage for our proposed product candidates. Public perception may be influenced by claims, such as claims that our technologies are unsafe, unethical or immoral and, consequently, our approach may not gain the acceptance of the public or the medical community. Negative public reaction to cell-based immunotherapy in general could result in greater government regulation and stricter labeling requirements of immunotherapy products, including our other product candidates, and could cause a decrease in the demand for our approved product and any other products we may develop. Moreover, our success will depend upon physicians specializing in the treatment of those diseases that our product or other product candidates target prescribing, and their patients being willing to receive treatments that involve the use of our product or other product candidates in lieu of, or in addition to, existing treatments they are already familiar with and for which greater clinical data may be available. The market for any products that we successfully develop will also depend on the cost of the products. Our goal is to reduce the cost of manufacturing and providing our therapies. However, unless we can reduce those costs to an acceptable amount, we may never be able to develop a commercially viable product. If we do not successfully develop and commercialize products based upon our approach or find suitable and economical sources for materials used in the production of our product or potential products, we will not become profitable, which would materially and adversely affect the value of our common stock. Our ANKTIVA therapies and our other therapies may be provided to patients in combination with other agents provided by third parties or our affiliates. The cost of such combination therapy may increase the overall cost of therapy and may result in issues regarding the allocation of reimbursements between our therapy and the other agents, all of which may affect our ability to obtain reimbursement coverage for the combination therapy from governmental or private third-party medical insurers.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our approved product or other product candidates.

We face an inherent risk of product liability as a result of the commercialization of our approved product and clinical development, testing and manufacturing of our other product candidates. For example, we may be sued if our approved product or other product candidates cause or are perceived to cause injury or are found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claim may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability, or a breach of warranties. Claims could also be asserted under state consumer protection acts. Large judgments have been awarded in class action lawsuits based on therapeutics that had unanticipated side effects. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our approved product or other product candidates. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in a regulatory investigation of the safety and effectiveness of our products, our third-party manufacturer’s manufacturing processes and facilities or our marketing programs and potentially a recall of our products or more serious enforcement action, including limitations on the approved indications for which our product candidates may be used or suspension or withdrawal of approvals, decreased demand for our products, injury to our reputation, costs to defend the related litigation, a diversion of management’s time and our resources, substantial monetary awards to trial participants or patients and a decline in our stock price.

Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of our approved product or other products we may develop, alone or with corporate collaborators. Our insurance policies may also have various exclusions, and we may be subject to product liability claims for which we have no coverage. While we have obtained clinical trial insurance for our clinical trials, we may have to pay amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. Even if our agreements with any future corporate collaborators entitle us to indemnification against losses, such indemnification may not be available or adequate should any claim arise.

We will face significant competition from other biotechnology and pharmaceutical companies and from non-profit institutions.

Competition in the field of cancer and infectious disease therapy is intense and is accentuated by the rapid pace of technological development. We compete with a variety of multi-national biopharmaceutical companies and specialized biotechnology companies, as well as technology being developed at universities and other research institutions. These competitors have developed, may develop, and are developing product candidates and processes competitive with our approved product or other product candidates. Research and discoveries by others may result in breakthroughs which may render our approved product

Table of Contents

or other product candidates obsolete even before they generate any revenues. We believe that a significant number of products are currently under development, and may become commercially available in the future, for the treatment of conditions for which our product treats or for which we are developing product candidates. Many of our competitors have several therapeutic products that have already been developed, approved and successfully commercialized, or are in the process of obtaining regulatory approval for their therapeutic products in the U.S. and internationally. Many of our competitors, either alone or with their strategic partners, have substantially greater financial, technical, and human resources than we do, as well as significantly greater experience in the discovery and development of product candidates, obtaining FDA and other regulatory approvals of treatments and commercializing those treatments. Accordingly, our competitors may be more successful in obtaining approval of treatments and achieving widespread market acceptance, rendering our treatments obsolete or non-competitive, possibly even before we are able to enter the market. Accelerated merger and acquisition activity in the biotechnology and biopharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

The availability and price of our competitors’ products could limit the demand and the price we are able to charge for our approved product or any of our other product candidates, if approved. The level of generic competition and the availability of reimbursement from government and other third-party payors will also significantly affect the pricing and competitiveness of our products.

We may not be able to implement our business plan if the acceptance of our approved product or other product candidates is inhibited by price competition or the reluctance of physicians to switch from other methods of treatment to our approved product, or if physicians switch to other new therapies, drugs or biologic products or choose to reserve our products for use in limited circumstances. We may be adversely impacted if any of these competitors gain market share as a result of new technologies, commercialization strategies or otherwise.

We may seek orphan drug status or Breakthrough Therapy, Fast Track or RMAT designations or other designation from the FDA or comparable non-U.S. regulatory authorities for one or more of our product candidates, but even if any such designation or status is granted, it may not lead to a faster development process or regulatory review and may not increase the likelihood that our product candidates will receive marketing approval, and we may be subject to significant costs including those associated with EAPs, and be unable to maintain any benefits associated with such designations or status, including market exclusivity.

We have been awarded Breakthrough Therapy,Fast Track andRMAT designations, and may seek in the future such designations for current or future product candidates. Receipt of a designation to facilitate product candidate development is within the discretion of the FDA. Accordingly, even if we believe one of our product candidates meets the criteria for a designation, the FDA may disagree. If we are unable to obtain such approval, we may be required to conduct additional preclinical studies or clinical trials beyond those that we contemplate, which could increase the expense of obtaining, and delay the receipt of, necessary marketing approvals. In any event, the receipt of such a designation for our product candidates may not result in a faster development process, review, or approval compared to product candidates considered for approval under conventional FDA procedures and does not ensure ultimate marketing approval by the FDA. In addition, the FDA may later decide that the product candidates no longer meet the designation conditions. See Item 1. “Business—Government Regulation—BLA/NDA Submission and Review by the FDA” for additional information regarding these designations. If granted, accelerated approval is usually contingent on the sponsor’s agreement to conduct, in a diligent manner, additional post-approval confirmatory studies to verify and describe the drug’s clinical benefit, and the FDA is permitted to require, as appropriate, that such studies be underway prior to approval or within a specified period after the date of approval. Sponsors must also update the FDA on the status of these studies, and the FDA has increased authority to withdraw approval of a drug granted accelerated approval on an expedited basis if the sponsor fails to conduct such studies in a timely manner, or send the necessary updates to the FDA, or if such post-approval studies fail to verify the drug’s predicted clinical benefit. Prior to seeking accelerated approval, we will seek feedback from the FDA or comparable non-U.S. regulatory authorities and will otherwise evaluate our ability to seek and receive such accelerated approval. There can be no assurance that after our evaluation of the feedback and other factors we will decide to pursue or submit a BLA for accelerated approval or any other form of expedited development, review or approval. Similarly, there can be no assurance that after subsequent feedback from the FDA or comparable non-U.S. regulatory authorities, we will

Table of Contents

continue to pursue or apply for accelerated approval or any other form of expedited development, review or approval, even if we initially decide to do so. Furthermore, if we decide to submit an application for accelerated approval, there can be no assurance that such application will be accepted or that any approval will be granted on a timely basis, or at all. The FDA or other comparable non-U.S. regulatory authorities could also require us to provide expensive investigational drug at non-commercial pricing or at no cost as part of a designation associated required EAP. For example, as part of our RMAT designation associated with lymphopenia and pancreatic cancer, we intend to submit an EAP for ANKTIVA and PD-L1 t-haNK in combination with standard-of-care chemotherapy/radiotherapy. The FDA or other comparable non-U.S. regulatory authorities could also require us to conduct further studies prior to considering our application or granting approval of any type, including, for example, if other products are approved via the accelerated pathway and subsequently converted by FDA to full approval. A failure to obtain accelerated approval or any other form of expedited development, review or approval for our product candidate would result in a longer time period to commercialization of such product candidate, could increase the cost of development of such product candidate, and could harm our competitive position in the marketplace. Moreover, even if we are able to obtain accelerated approval for any of our product candidates, there is no guarantee that post-approval studies will be able to confirm the clinical benefit, which could cause the FDA to withdraw our approval.

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition or for which there is no reasonable expectation that the cost of developing and making available the drug or biologic will be recovered from sales in the U.S. If a product that has orphan drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including a full BLA to market the same drug or biologic for the same indication for seven years, except in limited circumstances. We may seek orphan drug status for one or more of our product candidates, but exclusive marketing rights in the U.S. may be lost if we seek approval for an indication broader than the orphan designated indication and may be lost if the FDA later determines that the request for designation was materially defective or if we are unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition. In response to Catalyst Pharms., Inc. v. Becerra, 14 F.4th 1299 (11th Cir. 2021), the FDA clarified in a January 2023 notice that it intends to continue to apply its longstanding interpretation of the regulations to matters outside of the scope of the Catalyst order – that is, the agency will continue tying the scope of orphan-drug exclusivity to the uses or indications for which a drug is approved, which permits other sponsors to obtain approval of a drug for new uses or indications within the same orphan designated disease or condition that have not yet been approved. It is unclear how future litigation, legislation, agency decisions, and administrative actions will impact the scope of the orphan drug exclusivity.

As a condition of approval, the FDA may require that we implement various post-marketing requirements and conduct post-marketing studies, any of which would require a substantial investment of time, effort, and money, and which may limit our commercial prospects.

As a condition of biologic licensing, the FDA is authorized to require that sponsors of approved BLAs implement various post-market requirements, including REMS and Phase 4 trials. In connection with the regulatory approval of ANKTIVA with BCG for the treatment of adult patients with BCG-unresponsive NMIBC with CIS with or without papillary tumors, we are required to comply with certain post-marketing commitments, including completion of our QUILT 3032 clinical trial and annual reporting for up to four years, with a final report submission to the FDA by the end of 2029. If we receive approval of our other product candidates, the FDA may determine that similar or additional or more burdensome post-approval requirements are necessary to ensure that our product candidates are safe, pure and potent. For example, in connection with FDA approval of another company’s drug, the FDA required significant post-marketing commitments, including a Phase 4 trial, revalidation of a test method, and a substantial REMS program that included, among other requirements, the certification of hospitals and their associated clinics that dispensed the drug, including the implementation of a training program and limited distribution only to certified hospitals and their associated clinics. To the extent that we are required to establish and implement any post-approval requirements, we will likely need to invest a significant amount of time, effort and money. Such post-approval requirements may also limit the commercial prospects of our product candidates.

Table of Contents

We have never commercialized a product candidate before our approved product, and we may lack the necessary expertise, personnel and resources to successfully commercialize any products on our own or together with suitable collaborators. We may be unable to establish effective marketing and sales capabilities or enter into agreements with third parties or related parties to market and sell our other product candidates, if they are approved, and as a result, we may be unable to generate product revenues.

We have little to no prior experience in the marketing, sale and distribution of biopharmaceutical products. To achieve commercial success for our approved product and other product candidates, which we may license to others, we may rely on the assistance and guidance of those collaborators. In order to commercialize our approved product and our other product candidates for which we retain commercialization rights and marketing approval, if approved, we must continue to build out our marketing, sales and distribution capabilities, including a comprehensive healthcare compliance program, and/or arrange with third parties to perform these services, which will continue to take time and require significant financial expenditures, and could delay any product launch and we may not be successful in doing so. There are significant risks involved with building and managing a commercial infrastructure. We, our collaborators and third-party contractors, have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train, manage and retain medical affairs, marketing, sales and commercial support personnel. Recruiting, training, and retaining a sales force is expensive and time-consuming and could delay any product launch. If the commercial launch of our approved product or any other product candidate for which we or our third-party contractors recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we would have incurred these commercialization expenses prematurely or unnecessarily. These efforts may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel. In the event we are unable to develop a commercial infrastructure, we may not be able to commercialize our current or future product candidates, which would limit our ability to generate product revenues. Even if we and/or our potential partners and/or third-party contractors are able to effectively establish a sales force and develop a marketing and sales infrastructure, such sales force and marketing teams may not be successful in commercializing our approved product or any other current or future product candidates. To the extent we rely on third parties to commercialize any products for which we obtain regulatory approval, which we are doing to a certain extent in connection with our approved product launch, we may have less control over their sales efforts and could be held liable if they failed to comply with applicable legal or regulatory requirements.

If our approved product or any of our other product candidates do not achieve broad market acceptance, the revenues that we generate from their sales will be limited.

We are in the process of commercializing our approved product. Our approved product and other product candidates, if approved by the appropriate regulatory authorities for marketing and sale, may not gain acceptance among physicians, patients, third-party payors, and others in the medical community. If our approved product or any other product candidate for which we obtain regulatory approval does not gain an adequate level of market acceptance, we may not generate significant product revenues or become profitable. Market acceptance of our approved product or any other product candidates by the medical community, patients and third-party payors will depend on a number of factors, some of which are beyond our control. For example, physicians are often reluctant to switch their patients, and patients may be reluctant to switch from existing therapies even when new and potentially more effective or safer treatments enter the market. Efforts to educate the medical community and third-party payors on the benefits of our approved product and other product candidates may require significant resources and may not be successful. Even if the medical community accepts that our approved product and other product candidates are safe and effective for their approved indications, physicians and patients may not immediately be receptive to such approved product or other product candidates and may be slow to adopt them as an accepted treatment of the approved indications, including, for example, if third-party payors require high co-payments or if physicians perceive that reimbursement will not be available on a timely basis or at all. If our product or any of our other product candidates is approved but does not achieve an adequate level of market acceptance, we may not generate significant revenues and we may not become profitable. The degree of market acceptance of our approved product or any of our other product candidates will depend on a number of factors, including:

•the continued safety and efficacy of our approved product or other product candidates;

•the prevalence and severity of adverse events associated with such approved product or other product candidates;

•the clinical indications for which the products are approved and the approved claims that we may make for the products;

•limitations or warnings contained in the product’s FDA-approved labeling, including potential limitations or warnings for such products that may be more restrictive than other competitive products or distribution and use restrictions imposed by the FDA with respect to such approved product or other product candidates or to which we agree as part of a mandatory REMS or voluntary risk management plan;

Table of Contents

•changes in the standard-of-care for the targeted indications for such approved product or other product candidates;

•the relative difficulty of administration of our approved product or other product candidates;

•our ability to offer our approved product or other product candidates for sale at competitive prices, including the cost of treatment vs. economic and clinical benefit in relation to alternative treatments or therapies;

•the availability of adequate coverage or reimbursement by third parties, such as insurance companies and other healthcare payors, and by government healthcare programs, including Medicare and Medicaid;

•the extent and strength of our marketing and distribution of such approved product or other product candidates;

•the safety, efficacy and other potential advantages over, and availability of, alternative treatments already used or that may later be approved for any of our intended indications;

•the timing of market introduction of our approved product or other product candidates, as well as competitive products;

•the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

•the extent and strength of our third-party manufacturer and supplier support;

•adverse publicity about the product or favorable publicity about competitive products; and

•potential product liability claims.

If our approved product or any other product candidate that we commercialize fails to achieve market acceptance, it could have a material and adverse effect on our business, financial condition, results of operations, and prospects.

Our approved product and our product candidates may face competition sooner than anticipated.

The enactment of the BPCIA created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, the FDA cannot make an approval of an application for a biosimilar product effective until 12 years after the original branded product was approved under a BLA. Certain changes, however, and supplements to an approved BLA, and subsequent applications filed by the same sponsor, manufacturer, licensor, predecessor in interest or other related entity do not qualify for the 12-year exclusivity period.

Our approved product and/or product candidates may qualify for the BPCIA’s 12-year period of exclusivity. There is a risk that any product candidates we may develop that are approved as a biological product under a BLA would not qualify for the 12-year period of exclusivity or that this exclusivity could be shortened due to congressional action or otherwise, or that the FDA will not consider our approved product or any other product candidates we may develop to be reference products for competing products, potentially creating the opportunity for generic competition sooner than anticipated. Additionally, this period of regulatory exclusivity does not block companies pursuing regulatory approval via their own traditional BLA, rather than via the abbreviated pathway. Even if we receive a period of BPCIA exclusivity for our approved product, if subsequent products do not include a modification to the structure of the product that impacts safety, purity, or potency, we may not receive additional periods of exclusivity for those products. Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of our reference product candidates in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing. Medicare Part B encourages use of biosimilars by paying the provider the same percentage of the reference product average sale price as a mark-up, regardless of which product is reimbursed. It is also possible that payors will give reimbursement preference to biosimilars even over reference biologics absent a determination of interchangeability.

For our small molecular product candidates, if qualified, the regulatory exclusivity period is less than for our biologic product candidates. The FD&C Act provides a five-year period of non-patent marketing exclusivity within the U.S. to the first applicant to gain approval of an NDA for a drug where the FDA has not previously approved any other new drug containing the same active molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an abbreviated NDA or a 505(b)(2) NDA submitted by another company for a generic version of such drug where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement. The FD&C Act also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, which were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example, new indications, dosages or strengths of an existing drug. As such, we may face competition from generic versions of our small molecule product candidates, which will negatively impact our long-term business prospects and marketing opportunities.

We will need to obtain FDA approval of any proposed branded product names, and any failure or delay associated with such approval may adversely affect our business.

Any name we intend to use for our product candidates in the U.S. will require approval from the FDA regardless of whether we have secured a formal trademark registration from the USPTO. The FDA typically conducts a review of proposed product names, including an evaluation of the potential for confusion with other product names. The FDA may also object to a product name if it believes the name inappropriately implies medical claims or contributes to an overstatement of efficacy. If the FDA objects to any of our proposed product names, we may be required to adopt alternative names for our product candidates. If we adopt alternative names, we will lose the benefit of any existing trademark applications for such product candidate and may be required to expend significant additional resources in an effort to identify a suitable product name that would qualify under applicable trademark laws, not infringe or otherwise violate the existing rights of third parties, and be acceptable to the FDA. We may be unable to build a successful brand identity for a new product name in a timely manner or at all, which would limit our ability to commercialize our product candidates.

Our systems, infrastructure or data, or those used by our CROs, CMOs, clinical sites or other contractors or consultants, may fail or suffer a cyberattack, security breach or other incident, including a breakdown or compromise of the confidentiality, integrity and availability of our systems, networks or data, which could adversely affect the operation of our business and reputation.

We are and will be dependent upon information technology systems, infrastructure, and data. In the ordinary course of our business, we will directly or indirectly collect, store, transmit, and otherwise process sensitive and confidential information, including intellectual property, preclinical, and clinical trial data, proprietary business information, and personal information of our clinical trial patients and employees, including in our data centers and on our systems and networks or on those of third parties. The secure maintenance, transmission, and processing of data is critical to our operations. The multitude and complexity of our systems and those of our CROs, CMOs, clinical sites, or other contractors or consultants may subject them to various threats, including interruption, destruction, malicious intrusion, and random attack. Privacy or security breaches or other incidents, including by third parties, employees, contractors or others, may pose a risk that sensitive or confidential information, including our intellectual property, trade secrets or personal information of our employees, patients, or other business partners may be exposed to unauthorized persons or to the public. Further, as many of our employees work remotely, our reliance on our and third-party systems has increased substantially and is expected to continue to increase.

Despite the implementation of security measures, our systems, infrastructure and data, and those of our CROs, CMOs, clinical sites and other contractors and consultants, are subject to risks relating to cyberattacks, security breaches, or other incidents, including through viruses and other malware, employee error, unauthorized access, natural disasters, terrorism, war, fire, telecommunication and electrical failures, denial of service attacks, social engineering (including phishing attacks) and other means. As the cyberthreat landscape evolves, these cyberattacks are increasing in their frequency, sophistication and intensity and are becoming increasingly difficult to detect. The techniques used by cybercriminals change frequently, may not be recognized until launched and can originate from a wide variety of sources, including outside groups such as external service providers, organized crime affiliates, terrorist organizations or hostile foreign governments or agencies. Cyberattacks affect service reliability and threaten data confidentiality, integrity and availability. While we and our shared services partner, NantWorks, have

invested, and continue to invest, in the protection of our data, systems, and infrastructure, there can be no assurance that our efforts, or the efforts of our partners, vendors, CROs, CMOs, clinical sites and other contractors and consultants, will be successful. Any failure or perceived failure in our systems, infrastructure or data, or to identify or prevent cyberattacks, security breaches or other incidents, including service interruptions could adversely affect our business and operations, result in the loss, unavailability, misuse, unauthorized use or acquisition, or other unauthorized processing of critical or sensitive information, and result in financial, legal, business or reputational harm. In addition, our liability insurance may not be sufficient in type or amount to cover us against claims related to any such failures, security breaches, cyberattacks or other incidents.

If any such event were to occur, it could also cause interruptions in our operations, including a disruption of our product development programs. For example, the loss of clinical trial data from completed or ongoing clinical trials for a product candidate could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data or may limit our ability to effectively execute a product recall, if required. Any such event could result in liability, delays in the development and commercialization of product candidates, claims, demands or proceedings initiated by regulatory authorities or private parties, violations of laws, including laws that protect the privacy or security of personal information, significant liabilities, including regulatory penalties, damage to our reputation, and a loss of confidence in us and our ability to conduct clinical trials.

A pandemic, epidemic or outbreak of an infectious disease, such as COVID-19, or the perception of its effects, may materially and adversely affect our business, operations and financial condition.

Public health outbreaks, such as epidemics or pandemics may significantly disrupt our business. Such outbreaks pose the risk that we or our employees, contractors, suppliers, and other partners may be prevented from conducting business activities for an indefinite period of time due to the spread of the disease, due to shutdowns that may be requested or mandated by federal, state, and local governmental authorities or certain employers, or due to the economic consequences associated with the pandemic. Business disruptions could include disruptions or restrictions on our ability to travel, as well as temporary closures of our facilities and the facilities of our partners, clinical trial sites, service providers, suppliers, or CMOs. For example, the COVID-19 pandemic caused a temporary disruption in our ability to recruit participants for our clinical trials in the calendar year 2020 and the first quarter of 2021. While it is not possible to predict whether another pandemic, epidemic, or infectious disease outbreak similar to COVID-19 will materialize, any measures taken by governments and local authorities in response to such future health crises have the potential to disrupt and delay the initiation of new clinical trials, the progress of our ongoing clinical trials and our preclinical activities, and potentially the manufacture or shipment of both drug substance and finished drug product of our approved product and our other product candidates for preclinical testing and clinical trials, may adversely impact our business, financial condition, or operating results.

Risks Related to Reliance on Third Parties

We have relied and will continue to rely on third parties and related parties to conduct some of our preclinical studies and clinical trials, manufacture our approved product and other product candidates, and perform many essential services for any products that we commercialize, including services related to sales and marketing, distribution, government price reporting, customer service, accounts receivable management, cash collection and adverse event reporting. Any failure by a third party or related party to perform as expected, to comply with legal and regulatory requirements, to manufacture products in compliance with cGMP, or to conduct the clinical trials according to GCP guidelines, and in a timely manner, may delay or prevent our ability to commercialize our approved product, to seek or obtain regulatory approval for or commercialize our other product candidates or may subject us to regulatory sanctions.

Large-scale clinical trials require significant financial and management resources. We expect to be heavily reliant on third and related parties, including medical institutions, academic institutions, clinical investigators or CROs to conduct, supervise or monitor some or all aspects of our clinical trials, and in some cases, third-party CMOs to manufacture our approved product or other product candidates, which may force us to encounter delays and challenges that are outside of our control. Nevertheless, we are responsible for ensuring that each of our trials is conducted in accordance with the applicable trial protocol and legal, regulatory and scientific standards, and our reliance on CROs, clinical trial sites, and other third parties does not relieve us of these responsibilities. Our CROs and other third parties must communicate and coordinate with one another in order for our trials to be successful. We have a limited history of conducting clinical trials and have limited experience as a company in submitting and supporting the applications necessary to gain marketing approvals. Our relative lack of experience conducting clinical trials may contribute to our planned clinical trials not beginning or completing on time, if at all. Securing marketing approval also requires the submission of information about the product manufacturing process to, and inspection of manufacturing facilities and clinical trial sites by, applicable regulatory authorities.

For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial and for ensuring that our preclinical studies are conducted in accordance with GLP guidelines, as appropriate. Moreover, the FDA and comparable foreign regulatory authorities require us and the third parties upon which we intend to rely for conducting our clinical trials to comply with GCP guidelines for conducting, recording, and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity, and confidentiality of trial participants are protected. Regulatory authorities enforce these requirements through periodic inspections (including pre-approval inspections once a BLA or NDA is filed with the FDA) of trial sponsors, clinical investigators, trial sites, and certain third parties including CMOs. If we, our CROs, clinical trial sites, or other third parties fail to comply with applicable GCP guidelines or other regulatory requirements, we or they may be subject to enforcement or other legal actions, the clinical data generated in our clinical trials may be deemed unreliable and have to be repeated, and our submission of marketing applications may be delayed or the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with GCP guidelines.

We rely on third parties to manufacture, package, label, and ship our approved product and some of our other product candidates for the clinical trials that we conduct. Any performance failure on the part of these third parties could delay commercialization of our approved product or other product candidates, or the clinical development or marketing approval of our product candidates producing additional losses and depriving us of potential product revenues.
