ImmunityBio, Inc. (IBRX)

ITEM 7.     MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion and analysis of our financial condition and results of operations should be read together with the description of our business that appears in Part I, Item 1. “Business” and the consolidated financial statements and related notes thereto in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. This discussion contains forward-looking statements as a result of many factors, including those set forth under Part I, Item 1. “Business—Forward-Looking Statements” and Item 1A. “Risk Factors” and elsewhere in this Annual Report. These statements are based on our management’s beliefs and assumptions and on information currently available to our management. Actual results could differ materially from those discussed in or implied by such forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Annual Report, particularly in Part I, Item 1A. “Risk Factors.” Except as required by law, we do not undertake any responsibility to update any of these factors or to announce publicly any revisions to any of the forward-looking statements contained in this or any document, whether as a result of new information, future events, or otherwise.

ImmunityBio is a vertically-integrated commercial stage biotechnology company developing next-generation therapies that bolster the natural immune system to defeat cancers and infectious diseases. The company’s range of immunotherapy platforms, alone and together, act to drive an immune response with the goal of creating durable immune memory generating safe protection against disease. We are applying our science and platforms to treating cancers, including the development of potential cancer vaccines, as well as developing immunotherapies and cell therapies that we believe sharply reduce or eliminate the need for standard high-dose chemotherapy. These platforms and their associated product candidates are designed to be more effective, accessible, and easily administered than current standards of care in oncology and infectious diseases.

Our Approved Product – ANKTIVA

Our lead biologic product ANKTIVA is a novel first-in-class IL-15 receptor superagonist antibody-cytokine fusion protein. 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 (the “approved product”). ANKTIVA was approved with a label indicating an immunological mechanism of action which proliferates and activates NK, CD8+ and memory T cells without the proliferation of immunosuppressive T-reg cells leading to the establishment of memory T cells. We began commercial distribution of our approved product in May 2024.

We believe there is potential for ANKTIVA to become a therapeutic foundation across all phases of treatment, including in adjunctive therapy, to amplify, reactivate or extend the efficacy of standard of care. ANKTIVA is being clinically evaluated in multiple oncology indications. We believe that other oncology indications with registration potential for ANKTIVA include other types of NMIBC (BCG-unresponsive papillary, BCG-naïve CIS and BCG-naïve papillary), lung, colorectal, prostate and ovarian cancers, and GBM and NHL.

Data from multiple clinical trials suggest ANKTIVA has potential to enhance the activity of therapeutic mAbs, including CPIs (e.g., pembrolizumab/Keytruda), across a wide range of tumor types, including lung cancer. Further, ANKTIVA has been observed to increase lymphocyte count in healthy adults, making it a potential therapy to rescue lymphopenia. We are also exploring or pursuing several other studies of ANKTIVA in combination with our other product candidates, including in prostate cancer (ANKTIVA in combination with hAd5 PSA), colon cancer (ANKTIVA in combination with hAd5 TriAd), and NHL (ANKTIVA in combination with rituximab). We are also exploring ANKTIVA in infectious diseases, including HIV and long COVID.

Significant Developments

The following is a summary of selected significant developments affecting our business that occurred since the filing of our Quarterly Report dated September 30, 2024 with the SEC on November 12, 2024:

•ANKTIVA received a J-code assigned by the CMS in the U.S. for ANKTIVA, which became effective January 1, 2025.

•With a permanent J-code awarded in January 2025, our February 2025 ANKTIVA unit sales volume grew 97% over unit sales volume in December 2024 and 67% over unit sales volume in January 2025.

•We completed the submission of MAAs for the treatment of patients with BCG-unresponsive NMIBC with CIS with or without papillary tumors for ANKTIVA in combination with BCG to the MHRA in the UK in November 2024 and to the EMA in the EU in December 2024. Both MAAs were accepted for review, with the potential for approval in the UK and EU by 2026.

•In collaboration with Serum Institute, and in connection with our exclusive global supply arrangement that we announced during 2024, in February 2025 the FDA authorized an EAP allowing us to provide rBCG developed by Serum Institute to urologists to address the TICE BCG shortage in any settings where TICE BCG is approved, and we are also testing rBCG in an FDA-approved trial in the U.S. Serum Institute’s GMP capacity to manufacture large-scale volumes of rBCG, already tested for safety and efficacy in clinical trials in Europe in subjects with NMIBC, aims to address the shortage of TICE BCG, which we believe will help to ensure a reliable supply for patients in need. We expect to begin shipments of rBCG pursuant to the EAP during the first quarter of 2025.

•In January 2025, we announced a collaboration and supply agreement with BeiGene, Ltd. (to be renamed to BeOne Medicines, Ltd.) to conduct a confirmatory randomized Phase 3 clinical trial combining BeOne’s tislelizumab, a PD-1 CPI, and ANKTIVA in participants with advanced or metastatic NSCLC who have acquired resistance to immune CPI therapy.

•On February 27, 2025, the FDA granted us RMAT designation for ANKTIVA and CAR-NK (PD-L1 t-haNK) in combination with standard-of-care chemotherapy/radiotherapy indicated for the reversal of lymphopenia and treatment of multiply relapsed locally advanced or metastatic pancreatic cancer. This RMAT designation follows clinical data of ALC and significant overall survival correlations in QUILT trials across multiple tumor types including third-line or greater metastatic pancreatic cancer, checkpoint relapsed NSCLC, and supportive data from healthy volunteers. The reversal of lymphopenia by our IL-15 receptor superagonist is consistent with the mechanism of action of ANKTIVA demonstrating proliferation and activation of NK cells, CD4+ T cells, CD8+ T cells and memory T cells without upregulation of suppressive T-reg cells and approved in the ANKTIVA label (approved for the treatment of adult patients with BCG-unresponsive NMIBC with CIS with or without papillary tumors). We intend to submit a 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 which includes the first-in-class CAR-NK (PD-L1 t-haNK), and to provide data from fully enrolled clinical trials in metastatic pancreatic cancer (QUILT 88) and in checkpoint relapsed NSCLC (QUILT 3055, NSCLC Cohort) patients, as well as lymphopenia reversal across multiple tumor types (QUILT 3055, all Cohorts), with supportive data of lymphocyte proliferation in healthy volunteers (QUILT 1004). In addition, we intend to file an EAP for ANKTIVA and PD-L1 t-haNK in combination with standard of care chemotherapy/radiotherapy and to submit the protocol to the FDA.

Our Pipeline

Our proprietary platforms for the development of biologic products and product candidates include: (i) cytokine fusion proteins, (ii) vaccine vectors, and (iii) cell therapies. As of December 2024, our platforms have generated nine first-in-human therapeutic agents (including one agent approved by the FDA) that are currently or planned to be studied in clinical trials in liquid and solid tumors. These indications are among the most frequent and lethal cancer types and where there are high failure rates for existing standards of care or no available effective treatment. We are constantly monitoring and prioritizing clinical development based upon the availability of our resources and the efficacy and market developments of our competitors’ products and product candidates, among other factors.

Our platforms and their associated product and product candidates are designed to attack cancer and infectious pathogens by activating both the innate immune system, including NK cells, dendritic cells, and macrophages, as well as the adaptive immune system comprising B and T cells, in an orchestrated manner. The goal of this potentially best-in-class approach is to generate immunogenic cell death thereby eliminating rogue cells from the body whether they are cancerous or virally-infected. Our ultimate goal is to overcome the limitations of current treatments, such as CPIs, by turning immunologically cold, MHC-deficient tumors into hot tumors, and/or reducing the need for standard high-dose chemotherapy in cancer by employing a coordinated approach to establish “immunological memory” that confers long-term benefit for the patient.

Operating Results

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. Now that we have received FDA approval for ANKTIVA, 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, 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 do not expect additional revenue from our other product candidates unless and until we obtain regulatory approval of and commercialize any of our other product candidates, and we do not know when, or if, this will occur.

We expect to continue to incur significant expenses as we seek to expand our business, including commercializing our approved product, seeking regulatory approvals, 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, and increasing our manufacturing capabilities. Furthermore, the timing and magnitude of our approved product sales and revenue remain uncertain and may take a significant amount of time to materialize, if ever.

We have incurred net losses in each year since our inception and, as of December 31, 2024, we had an accumulated deficit of $3.4 billion. During the years ended December 31, 2024, 2023 and 2022, net losses attributable to ImmunityBio common stockholders were $413.6 million, $583.2 million, and $416.6 million, respectively. Substantially all of our net losses resulted principally from costs incurred in connection with our ongoing clinical trials and operations, our research and development programs, and from selling, general and administrative costs associated with our operations, including stock-based compensation expense.

As of December 31, 2024, we had 680 employees. Personnel of related companies who provide corporate, general and administrative, certain research and development, and other support services under our shared services agreement with NantWorks are not included in this number. See Note 13 “Related-Party Agreements” 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. In anticipation of the ongoing commercialization of our approved product, we expect to continue to incur significant expenses and increasing operating expenses for the foreseeable future, which may fluctuate significantly from quarter-to-quarter and year-to-year. See “—Future Funding Requirements” below for a discussion of our anticipated expenditures and sources of capital we expect to access to fund these expenditures.

Collaboration Agreements

We anticipate that strategic collaborations will continue to be an integral part of our operations, providing opportunities to leverage our partners’ expertise and capabilities to gain access to new markets for our approved product and acquire new technologies or further expand the potential of our technologies, approved product and product candidates across relevant platforms. We believe we are well positioned to become a leader in immunotherapy due to our broad and vertically-integrated platforms and through complementary strategic partnerships.

We believe that our innovative approach to orchestrate and combine therapies for optimal immune system response will become a therapeutic foundation across multiple indications. Additionally, we believe that data from multiple clinical trials indicates ANKTIVA has broad potential to enhance the activity of therapeutic mAbs, including CPIs, across a wide range of tumor types and potentially rescue lymphopenia by proliferation and activation of NK and T cells. We may also enter into supply arrangements for various investigational agents to be used in our clinical trials. See Part I, Item 1. “Business—Collaboration and License Agreements” in this Annual Report for a more detailed discussion regarding our collaboration and license agreements.

Contingent Value Rights

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, our Founder, Executive Chairman and Global Chief Scientific and Medical Officer, and his related party hold approximately $139.8 million of net sales CVRs. See Note 9 “Commitments and Contingencies” 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 regarding the CVRs.

Components of our Results of Operations

Product Revenue, Net

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.

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. Now that we have received FDA approval for ANKTIVA, 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, 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 do not expect additional revenue from our other product candidates unless and until we obtain regulatory approval of and commercialize any of our other product candidates, and we do not know when, or if, this will occur.

Cost of Sales

Cost of sales consists primarily of third-party manufacturing costs, distribution, and overhead costs related to ANKTIVA sales. Cost of sales may also include costs related to excess or obsolete inventory adjustment charges, abnormal costs, unabsorbed manufacturing and overhead costs, and manufacturing variances. All costs associated with the production of ANKTIVA prior to receiving regulatory approval were expensed in research and development expense, on the consolidated statement of operations in the period incurred and therefore are not reflected in cost of sales. We expect the cost of sales for ANKTIVA to increase in relation to product revenues as we deplete these inventories.

Operating Expenses

We generally classify our operating expenses into research and development, and selling, general and administrative expenses. Personnel costs, including salaries, benefits, bonuses, and stock-based compensation expense comprise a significant component of our research and development, and selling, general and administrative expense categories. We allocate expenses associated with our facilities and information technology costs between these two categories, primarily based on the nature of each cost.

Research and Development

Research and development expense consists of expenses incurred while performing research and development activities to discover and develop our technology and product candidates. This includes conducting preclinical studies and clinical trials, manufacturing development efforts, and activities related to regulatory submissions for our approved product and product candidates. We expense research and development costs as they are incurred.

Our research and development expenses primarily consist of:

•clinical trial and regulatory-related costs;

•expenses incurred under agreements with investigative sites and consultants that conduct our clinical trials;

•expenses incurred under collaborative agreements;

135

Table of Contents

•manufacturing and testing costs and related supplies and materials;

•employee-related expenses, including salaries, benefits, travel and stock-based compensation; and

•facility expenses dedicated to research and development.

The company classifies its research and development expenses as either external or internal. The company’s external research and development expenses support its various preclinical and clinical programs. The company’s internal research and development expenses include payroll and benefits expenses, facilities and equipment expense, and other indirect research and development expenses incurred in support of its research and development activities. The company’s external and internal resources are not directly tied to any one research or drug discovery program and are typically deployed across multiple programs and are not allocated to specific product candidates or development programs.

We expect our research and development expenses to increase significantly for the foreseeable future as we continue to invest in research and development activities related to expanding our product into new indications and markets, developing our other product candidates, and conducting our ongoing and planned clinical trials.

The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. The successful development of product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs required to complete the remaining development of our other product candidates or to expand potential approved markets and indications for ANKTIVA. This is due to the numerous risks and uncertainties associated with the development of product candidates.

The costs of clinical trials may vary significantly over the life of a project owing to, but not limited to, the following:

•per patient trial costs;

•the number of sites included in the clinical trials;

•the countries in which the clinical trials are conducted;

•the length of time required to enroll eligible patients;

•the number of patients that participate in the clinical trials;

•the number of doses that patients receive;

•the cost of comparative or combination agents used in clinical trials;

•the drop-out or discontinuation rates of patients;

•potential additional safety monitoring or other studies or incremental cohorts requested by regulatory agencies;

•the duration of patient follow-up; and

•the safety profile and efficacy of the product candidate.

We have only one approved product, ANKTIVA, for which we received approval from the FDA on April 22, 2024. We began commercial distribution of our approved product in May 2024. There can be no assurance that our other product candidates will be approved for commercial sale by the FDA in the near term, if ever.

Selling, General and Administrative

Selling, general and administrative expense consists primarily of salaries and personnel-related costs, including employee benefits and any stock-based compensation, for employees performing functions other than research and development. This includes personnel in executive, finance, human resources, information technology, legal, sales and administrative support functions. Other selling, general and administrative expenses include sales and marketing costs, facility-related costs not otherwise allocated to research and development expense, professional fees for auditing, tax and legal services, advertising costs, expenses associated with strategic business transactions and business development efforts, obtaining and maintaining patents, consulting costs, royalties and licensing costs, and costs of our information systems.

136

Table of Contents

We expect that our selling, general and administrative expense will increase for the foreseeable future as we commercialize our approved product and expand operations, build out information systems and increase our headcount to support continued research activities and the development of our clinical programs. We have incurred and expect that we will continue to incur in the future, additional costs associated with operating as a public company, including costs to comply with stock exchange listing and SEC requirements, future funding efforts, corporate governance, internal controls, investor relations, disclosure and similar requirements applicable to public companies. Additionally, if and when we believe that a regulatory approval of one of our other product candidates appears likely, we expect to incur significant increases in our selling, general and administrative expense relating to the sales and marketing of any additional approved product candidate.

Other Income (Expense), Net

Other income (expense), net consists primarily of interest and investment income (loss), interest expense (including amortization of debt discounts), unrealized gains and losses from investments in equity securities and equity-method investments, changes in fair value of warrant liabilities, derivative liabilities, and convertible notes, realized gains and losses on debt and equity securities, and gains and losses on foreign currency transactions.

Income Taxes

We are subject to U.S. federal income tax, as well as income tax in Italy, South Korea, California and other states. From inception through December 31, 2024, we have not been required to pay U.S. federal and state income taxes because of current and accumulated NOLs.

Discussion of Consolidated Results of Operations

Comparison of the Years Ended December 31, 2024 and 2023

Product Revenue, Net

Product revenue, net increased $14.1 million during the year ended December 31, 2024, as compared to the year ended December 31, 2023. The increase was driven by sales of ANKTIVA after FDA approval in April 2024.

Other Revenues

Other revenues are consistent during the year ended December 31, 2024, as compared to the year ended December 31, 2023.

138

Table of Contents

Cost of Sales

We did not report cost of sales during the years ended December 31, 2024 and 2023. Cost of sales consists primarily of third-party manufacturing, distribution and overhead costs. All costs associated with the production of ANKTIVA prior to receiving regulatory approval were expensed in research and development expense, on the consolidated statement of operations in the period incurred and therefore are not reflected in cost of sales. As a result, our initial product gross margin is higher as our pre-launch inventory costs are not included in the cost of sales. We expect the cost of sales for ANKTIVA to increase in relation to product revenues as we deplete these inventories.

Research and Development Expense

Research and development expense decreased $42.2 million during the year ended December 31, 2024, as compared to the year ended December 31, 2023. The following table summarizes our research and development expenses during the years ended December 31, 2024 and 2023, together with the changes in those items (in thousands):

Research and development expense decreased $42.2 million primarily attributable to the following:

•a $37.9 million decrease in external research and development expenses that was primarily due to a reduction in CMO fees and testing services, a reduction in clinical trial costs, and a reduction in outside service costs;

•a $1.8 million increase in personnel-related costs that was primarily due to an increase in salary and benefits expenses from the expansion of the regulatory and sales teams during the year ended December 31, 2024, a reversal in 2023 of the 2022 accrued discretionary bonuses and a reduction in headcount during the year ended December 31, 2023, partially offset by an increase in shared service costs charged out and a decrease in stock-based compensation costs due to the prior years’ retention awards fully vesting during the year ended December 31, 2024;

•a $0.4 million increase in equipment, depreciation, and facility costs that was primarily due to increases in software purchases, facility expenses and common area maintenance costs, partially offset by decreases in depreciation and amortization expenses and lease expenses; and

•a $6.5 million decrease in other research and development costs, primarily attributable to lower material supply costs due to decreased production activities, a reclass of overhead costs to capitalized inventory and lower research agreement expenses, partially offset by an increase from no costs allocated to a joint venture and an increase in drug costs.

We expect our research and development expenses to increase significantly for the foreseeable future as we continue to invest in research and development activities related to developing our product candidates and conduct our ongoing and planned clinical trials.

139

Table of Contents

Selling, General and Administrative Expense

Selling, general and administrative expense increased $39.2 million during the year ended December 31, 2024, as compared to the year ended December 31, 2023. The rise in expenses was primarily due to a $19.8 million increase in legal expenses driven by higher defense and settlement costs and increased general legal services, a $14.6 million increase in consulting fees primarily associated with commercial readiness activities, an $8.3 million increase in salary and benefits primarily from the reversal in 2023 of the 2022 accrued discretionary bonuses, and a reduction in headcount during the year ended December 31, 2023, a $2.2 million increase in other operating costs due to post commercialization marketing activities, a $1.3 million increase in license fees, a $1.1 million increase in audit and tax fees, a $0.9 million increase in recruiting and training costs and a $0.4 million increase in travel expenses, partially offset by a $9.4 million decrease in stock-based compensation expense.

Impairment of Intangible Assets

Impairment of intangible assets decreased $0.9 million during the year ended December 31, 2024 as compared to the year ended December 31, 2023. The $0.9 million impairment charge during the year ended December 31, 2023 was related to indefinite-lived intangible assets associated with the Tarmogen platform as the research and development program was limited. There was no impairment of intangible assets incurred during the year ended December 31, 2024.

Other Income (Expense), Net

Other income (expense), net decreased $152.2 million during the year ended December 31, 2024, as compared to the year ended December 31, 2023. The reduction in other income (expense), net was primarily due to a change of $79.7 million in fair value of convertible notes driven by the revaluation gain of $43.5 million during the year ended December 31, 2024, as compared to the $36.2 million loss during the year ended December 31, 2023, a change of $67.6 million due to the reduction of fair value of warrant liabilities, a decrease of $14.3 million in interest expense (including amounts with related parties), a change of $13.5 million in the fair value of derivative liabilities, a decrease of $7.5 million due to loss on equity method investments recorded during the year ended December 31, 2023, an increase of $6.8 million in interest and investment income, net and a decrease of $2.2 million in other income (expense), net (including amounts with related parties), partially offset by an increase of $39.4 million in interest expense related to the revenue interest liability.

Comparison of the Years Ended December 31, 2023 to 2022

See Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations” of our Annual Report filed with the SEC on March 19, 2024 for a discussion of the company’s results of operations during the year ended December 31, 2023 compared to the year ended December 31, 2022.

Financial Condition, Liquidity and Capital Resources

Sources of Liquidity

From inception through December 31, 2024, we have funded our operations primarily through proceeds from the issuance of related-party promissory notes, sales of common stock under our shelf registration statements and through RDOs, and a RIPA financing.

Cash and Marketable Securities on Hand

As of December 31, 2024, we had cash and cash equivalents, and marketable securities of $149.8 million compared to $267.4 million as of December 31, 2023. We have typically invested our cash in a variety of financial instruments and classified these investments as available-for-sale. 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 risks. The general condition of the financial markets and the economy may increase those risks and may affect the value and liquidity of investments and restrict our ability to access the capital markets.

Table of Contents

Shelf Registration Statements

During 2023, we filed a $750.0 million shelf registration statement with the SEC on Form S-3 for the offering and sale of equity and equity-linked securities, including common stock, preferred stock, debt securities, depositary shares, warrants to purchase common stock, preferred stock or debt securities, subscription rights, purchase contracts, and units. As of December 31, 2024, we had $565.6 million available for use under this shelf.

In April 2024, we filed a shelf registration statement with the SEC on Form S-3ASR pursuant to which we may, from time to time, sell an indeterminate amount of our common stock, preferred stock, debt securities, depositary shares, warrants, subscription rights, purchase contracts, or units, and an associated prospectus related to the ATM.

Exercise of Warrants

Pursuant to warrant agreements issued in connection with our RDOs, we issued warrants to institutional holders. During the year ended December 31, 2024, institutional holders exercised a total of 22,242,740 warrants pursuant to the warrant agreements at an exercise price of $3.2946 per share resulting in the issuance of 22,242,740 shares of the company’s common stock for proceeds totaling $73.3 million. As of December 31, 2024, a total of 6,399,171 warrants remain outstanding with an exercise price of $3.2946 per share and an expiration date of July 24, 2026.

Revenue Interest Purchase Agreement

On December 29, 2023, we entered into the RIPA with Infinity and Oberland. Pursuant to the RIPA, Oberland had the option to purchase additional Revenue Interests from us in exchange for a $100.0 million Second Payment upon satisfaction of certain conditions in the RIPA, including receipt of approval from the FDA of our BLA for ANKTIVA on or before June 30, 2024. On April 22, 2024, the FDA approved our product ANKTIVA and as a result, on May 13, 2024 Oberland purchased additional Revenue Interests from us for a gross purchase price of $100.0 million, less certain issuance costs.

As consideration for the aforementioned payments, Oberland has the right to receive quarterly Revenue Interest Payments from us based on, among other things, a certain percentage of our net sales during such quarter, which are tiered payments ranging from 4.5% to 10.0% (before funding of the Second Payment, 3.0% to 7.0%) of the company’s worldwide net sales, excluding those in China. 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 regarding our payment obligations under the RIPA.

Conversion of Related-Party Promissory Notes

On December 10, 2024 in connection with an equity offering, the company received written notices from Nant Capital, the holder of the $30.0 million promissory note due December 31, 2025 and the $200.0 million promissory note due September 11, 2026, of its election to convert the entire outstanding principal and accrued interest due under the existing notes into shares of the company’s common stock. As of such date, the total outstanding principal and accrued and unpaid interest due under the existing notes of approximately $30.7 million was converted into 13,475,172 shares of the company’s common stock at a price of $2.28 per share (for the $30.0 million note) and approximately $200.7 million was converted into 103,710,088 shares of the company’s common stock at a price of $1.9350 per share (for the $200.0 million note) in accordance with the terms of the existing promissory notes.

See Note 12 “Related-Party Debt” 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 regarding our related-party debt.

Stock Purchase and Option Agreement

On December 29, 2023 and in connection with the RIPA, we entered into an SPOA with Oberland. Under this agreement, Oberland had an option to purchase up to $10.0 million of our common stock, at a price per share to be determined by reference to the 30-day trailing volume weighted-average price of our common stock, calculated from the date of exercise. The option is exercisable by Oberland at any time until the earliest of (i) December 29, 2028, (ii) a change of control of the company, or (iii) a sale of substantially all of the company’s assets. Among other limitations, the option may only be exercised to the extent that the common stock issuable pursuant to such exercise would not exceed 19.9% of the common stock outstanding immediately after giving effect to such exercise.

Pursuant to the SPOA, in April 2024 Oberland exercised its option to purchase 858,990 shares of our common stock at an exercise price of $5.8208 per share generating net proceeds of approximately $4.9 million. In relation to this transaction, we recorded $7.6 million in additional paid-in capital, on the statement of stockholders’ deficit during the year ended December 31, 2024. Following such exercise, approximately $5.0 million remains available for future exercise under the SPOA as of December 31, 2024.

Uses of Liquidity

In addition to the cash used to fund our operating activities discussed in “—Future Funding Requirements” below, we will require cash to settle the following obligations:

•As of December 31, 2024, our indebtedness payable at maturity is $505.0 million. This convertible promissory note is held by Nant Capital, an entity affiliated with Dr. Soon-Shiong. In connection with the RIPA, our related-party promissory note is a general unsecured obligation of the company that is subordinated in right of payment to indebtedness, obligations, and other liabilities under the RIPA, the Revenue Interests issued pursuant to such agreement, and refinancing of the foregoing.

There can be no assurance that the company can refinance this promissory note 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 refinanced indebtedness would increase. These risks could materially adversely affect the company’s financial condition, cash flows and results of operations.

•On December 29, 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 will be tiered payments initially ranging from 4.5% to 10.0% (before funding of the Second Payment, 3.0% to 7.0%), subject to increase or decrease, following December 31, 2029 (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 True-Up Payment to Oberland in an amount equal to 100% of the Cumulative Purchaser Payments as of the Test Date, less the aggregate amount of our previous payments to Oberland as of the Test Date. 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 regarding the RIPA.

•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. We may need to seek additional sources of capital to satisfy the CVR obligations if they are achieved.

•In connection with our acquisition of VivaBioCell, we are obligated to pay the former owners approximately $2.1 million of contingent consideration upon the achievement of a regulatory milestone relating to the GMP-in-a-Box technology.

Discussion of Consolidated Cash Flows

The following discussion of ImmunityBio’s cash flows is based on the consolidated statements of cash flows in Part II, Item 8. “Financial Statements and Supplementary Data” and is not meant to be an all‑inclusive discussion of the changes in its cash flows for the years presented below.

The following table sets forth our primary sources and uses of cash for the years indicated (in thousands):

Operating Activities

During the year ended December 31, 2024, net cash used in operating activities of $391.2 million consisted of a net loss of $413.6 million and $19.4 million of cash used in net working capital, partially offset by $41.8 million in adjustments for non-cash items.

Adjustments for non-cash items primarily consisted of $38.0 million of non-cash interest expense related to the revenue interest liability, $34.4 million in stock-based compensation expense, $22.6 million in amortization of related-party note discounts, $17.6 million in depreciation and amortization expense, $5.8 million in non-cash lease expense related to operating lease right‑of‑use assets, $1.2 million in non-cash interest primarily related to related-party promissory notes, $0.6 million in unrealized losses on equity securities driven by a decrease in the value of our investments, and $0.1 million in other items, reduced by a $43.5 million change in the fair value of a related-party convertible note, a $20.0 million change in fair value of warrant liabilities, a $13.5 million change in the fair value of derivative liabilities, and $1.5 million of accretion of discounts on marketable debt securities.

During the year ended December 31, 2023, net cash used in operating activities of $366.8 million consisted of a net loss of $583.9 million, partially offset by $213.1 million in adjustments for non-cash items and $4.0 million of cash provided by net working capital. Adjustments for non-cash items primarily consisted of $49.2 million in stock-based compensation expense, $47.6 million in change in fair value of warrant liabilities, $42.4 million in amortization of debt issuance costs and accretion of discounts, $36.2 million in change in fair value of convertible notes, $18.5 million in depreciation and amortization expense, $8.9 million in non-cash interest primarily related to related-party promissory notes, $6.1 million in non-cash lease expense related to operating lease right‑of‑use assets, $2.0 million of transaction costs allocable to warrant liabilities, $1.6 million in unrealized losses on equity securities driven by a decrease in the value of our investments, $0.9 million in loss on impairment of intangible assets, and $0.3 million of non-cash interest expense related to the revenue interest liability, partially offset by $0.5 million in other items and a decrease of $0.1 million in amortization of premiums, net of discounts on marketable debt securities. The changes in net working capital consisted primarily of an increase of $6.7 million in accrued expenses, a decrease of $6.0 million in prepaid expenses and other current assets, and a decrease of $1.9 million in other assets, partially offset by a decrease of $6.5 million in accounts payable, a decrease of $3.0 million in operating lease liabilities, and a decrease of $1.1 million in due to related parties.

We have historically experienced negative cash flows from operating activities, with such negative cash flows likely to continue for the foreseeable future.

Investing Activities

During the year ended December 31, 2024, net cash used in investing activities was $12.2 million, which included cash outflows of $140.2 million for purchases of marketable debt securities, $6.9 million in purchases of property, plant and equipment, $1.0 million used for the acquisition of a business, net of transaction costs, and $0.7 million cash paid for other investments, partially offset by proceeds of $136.6 million from maturities and sales of marketable debt and equity securities.

During the year ended December 31, 2023, net cash used in investing activities was $30.5 million, which included cash outflows of $30.6 million in purchases of property, plant and equipment (including construction in progress and the completion of a warehouse facility), and $10.4 million in purchases of marketable debt securities, partially offset by cash inflows of $10.5 million from maturities and sales of marketable debt and equity securities.

Our investments in property, plant and equipment are primarily related to acquisitions of equipment that will be used for the manufacturing of our approved product and product candidates and expenditures related to the buildout of our manufacturing facilities. We expect to accelerate our capital spending as we scale our GMP manufacturing capabilities, which will require significant capital for the foreseeable future.

Financing Activities

During the year ended December 31, 2024, net cash provided by financing activities was $281.6 million, which consisted of $111.4 million in net proceeds from equity offerings, $97.0 million in net proceeds from payments received pursuant to the RIPA, $73.3 million of proceeds from the exercise of warrants, $4.9 million in net proceeds from the partial exercise of the Oberland stock option, and $0.7 million in proceeds from the exercise of stock options, partially offset by $5.6 million related to net share settlement of vested RSUs for payment of payroll tax withholding and $0.1 million in principal payments of finance leases.

During the year ended December 31, 2023, net cash provided by financing activities was $558.3 million, which consisted of $258.7 million in net proceeds from issuances of related-party promissory notes, $192.8 million in net proceeds from payments received pursuant to the RIPA, $100.5 million in net proceeds from equity offerings, $9.5 million in net proceeds from issuance of common stock in connection with the RIPA, and $0.3 million in proceeds from the exercise of stock options, partially offset by $3.4 million related to net share settlement of vested RSUs for payment of payroll tax withholding, and $0.1 million used for principal payments of finance leases.

Comparison of the Years Ended December 31, 2023 to 2022

See Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations” of our Annual Report filed with the SEC on March 19, 2024 for a discussion of the company’s consolidated cash flows for the year ended December 31, 2023 compared to the year ended December 31, 2022.

Future Funding Requirements

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.

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. Now that we have received FDA approval for ANKTIVA, 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, 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 do not expect additional revenue from our other product candidates unless and until we obtain regulatory approval of and commercialize any of our other product candidates, and we do not know when, or if, this will occur. In addition, we expect our operating expenses to significantly increase in connection with our ongoing development activities,

144

Table of Contents

particularly as we continue the research, development and clinical trials of, and seek regulatory approval for, our other product candidates. We have also incurred and expect that we will continue to incur in the future additional costs associated with operating as a public company as well as costs related to future fundraising efforts. In addition, subject to obtaining regulatory approval of our other product candidates, we expect to incur significant incremental commercialization expenses for product sales, marketing, manufacturing and distribution. We anticipate that we will need substantial additional funding in connection with our continuing operations.

We expect that our operating expenses will increase substantially if and as we:

•commercialize our approved product;

•continue research and development, including preclinical and clinical development of our other existing product candidates;

•seek regulatory approval of our approved product in incremental markets and indications and potentially seek regulatory approval for our other product candidates;

•seek to discover and develop additional product candidates;

•establish a commercialization infrastructure and scale up our manufacturing and distribution capabilities to commercialize any of our other product candidates for which we may obtain regulatory approval;

•seek to comply with regulatory standards and laws;

•maintain, leverage and expand our intellectual property portfolio;

•hire clinical, manufacturing, scientific and other personnel to support our product candidates’ development and future commercialization efforts;

•add operational, financial and management information systems and personnel; and

•incur additional legal, accounting and other expenses in operating as a public company.

As a result of continuing anticipated operating cash outflows as we commercialize our approved product and accelerate our development efforts, we believe that substantial doubt exists regarding our ability to continue as a going concern without additional funding or financial support. However, we believe our existing cash and cash equivalents, and investments in marketable securities; sales of our approved product; capital to be raised through equity offerings, including but not limited to, the offering, issuance and sale by us of our common stock under the February 2023 shelf registration statement, of which we had $565.6 million available for future offerings as of December 31, 2024; and our potential ability to borrow from affiliated entities will be sufficient to fund our operations through at least the next 12 months following the issuance date of the consolidated financial statements based primarily upon our Founder, Executive Chairman and Global Chief Scientific and Medical Officer’s intent and ability to support our operations with additional funds, including loans from affiliated entities, as required, which we believe alleviates such doubt. In addition to funds from the future sales of our approved product, which we expect to take time to establish, we may also seek to sell additional equity, through one or more follow-on public offerings, or in separate financings, or obtain a credit facility, issue other debt in compliance with the terms of the RIPA, or engage in strategic partnership transactions. However, we may not be able to secure such external financing in a timely manner or on favorable terms, if at all. Without additional funds, we may choose to delay or reduce our operating or investment expenditures. Further, because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we may need additional funds to meet our needs sooner than planned.

We will need to obtain additional financing to fund our future operations, including completing 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.

145

Table of Contents

Our future funding requirements will depend on many factors, including, but not limited to:

•our ability and the time required to successfully commercialize our approved product;

•progress, timing, number, scope and costs of researching and developing our product candidates and our ongoing, planned and potential clinical trials;

•time and cost of regulatory approvals;

•our ability to successfully commercialize any of our other product candidates, if approved and the costs of such commercialization activities;

•revenue from product candidates that we may commercialize, if any, including the selling prices for such potential products and the availability of adequate third-party coverage and reimbursement for patients;

•interest and principal payments on our related-party promissory note, and repayment of Revenue Interests and Test Date payments due under the RIPA;

•cost of building, staffing and validating our own manufacturing facilities in the U.S., including having a product candidate successfully manufactured consistent with FDA and EMA regulations;

•terms, timing and costs of our current and any potential future collaborations, business or product acquisitions, CVRs, milestones, royalties, licensing or other arrangements that we have established or may establish;

•time and cost necessary to respond to technological, regulatory, political and market developments; and

•costs of filing, prosecuting, maintaining, defending and enforcing any patent claims and other intellectual property rights.

Unless and until we can generate a sufficient amount of revenues, we may finance future cash needs through public or private equity offerings, license agreements, debt financings, collaborations, strategic alliances and marketing 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 or through 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 terms may include liquidation or other preferences that adversely affect your rights as a stockholder. The incurrence of additional indebtedness would result in increased fixed payment obligations and could involve certain restrictive covenants, 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 and our revenue interest liability may come due. 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. 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.

Contractual Obligations

We have material cash requirements to pay related-party affiliates and third parties under various contractual obligations discussed below:

•We are obligated to make payments to several related-party affiliates under written agreements and other informal arrangements. We are also obligated to pay interest and to repay principal under our related-party promissory note. See Note 12 “Related-Party Debt” of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for information regarding our financing obligations.

146

Table of Contents

•We are obligated to make payments to Oberland associated with our revenue interest liability, which do not have a fixed repayment schedule. Oberland’s right to receive payments under the RIPA shall terminate when Oberland has received maximum payments (including any True-Up Payment) equal to 195.0% of the then Cumulative Purchaser Payments unless the RIPA is terminated prior to such date.

Under the terms of the agreement, prior to the Test Date, every $100.0 million of worldwide net sales, excluding those in China, of less than or equal to $600.0 million in a calendar year will result in a tiered Revenue Interest Payment of approximately $10.0 million or 10.0% (after funding of the Second Payment). Worldwide net sales, excluding those in China, for a calendar year exceeding $600.0 million will result in a tiered Revenue Interest Payment of approximately $4.5 million or 4.5% (after funding of the Second Payment) for every $100.0 million of worldwide net sales, excluding those in China, above the threshold.

In the future, cumulative worldwide net sales, excluding those in China, levels up to the Test Date will determine whether or not we are required to make a True-Up Payment and implement modified payment rates. The amount of the obligation and timing of payment is likely to change. 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 regarding the RIPA.

•We are obligated to make payments under our operating leases, which primarily consist of facility leases. See Note 10 “Lease Arrangements” and Note 13 “Related-Party Agreements” of the “Notes to Consolidated Financial Statements” that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for information regarding our lease obligations.

•In connection with the acquisitions of Altor and VivaBioCell, we are obligated to pay contingent consideration upon the achievement of certain milestones. See Note 9 “Commitments and Contingencies—Contingent Consideration Related to Business Combinations” of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for information regarding our contingent consideration obligations.

•We have certain contractual commitments to make payments to related-party affiliates and third parties that are expected to be paid during the following periods:

◦Fiscal Year 2025 – $37.0 million is estimated to be payable, primarily related to capital expenditures and open purchase orders as of December 31, 2024 for the acquisition of goods and services in the ordinary course of business, and near-term upfront milestone payments to third parties. The timing of payment depends on the actual progress of buildouts, completion of services, and the realization of milestones associated with third-party agreements; and

◦Fiscal year 2026 and beyond – Up to a maximum of $387.8 million as of December 31, 2024 based on the achievement of various development, regulatory and commercial milestones for agreements with third parties. These payments may not be realized or may be modified and are contingent upon the occurrence of various future events, substantially all of which have a high degree of uncertainty of occurring.

See Note 9 “Commitments and Contingencies—Unconditional Purchase Obligations” of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for information on these unconditional purchase obligations.

•In connection with our leasehold interest in the Dunkirk Facility, we committed to spend an aggregate of $1.52 billion on operational expenses during the initial 10-year term, and an additional $1.50 billion on operational expenses if we elect to renew the lease for the additional 10-year term. These amounts are not included in the discussion above. See Note 8 “Collaboration and License Agreements and Acquisition—Acquisition” 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 on these obligations.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Those estimates can be complex and actual results could differ materially from those estimates. Estimates are assessed each period and updated to reflect current information.

While our significant accounting policies are more fully described in the notes accompanying our consolidated financial statements that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report, we believe the following accounting policies to be the most critical in understanding the judgments and estimates we use in preparing our consolidated financial statements:

Revenue Recognition

Product Revenue, Net

After FDA approval in April 2024, the company began recognizing revenue from the sale of ANKTIVA in accordance with FASB ASC Topic 606, Revenue from Contracts with Customers (ASC 606). The provisions of ASC 606 require the following steps to determine revenue recognition: (i) identification of contract with the customers; (ii) identification of performance obligations; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) we satisfy each performance obligation. At contract inception, we assess the goods or services promised within each contract, determine whether each promised good or service is distinct and identify those that are performance obligations. We recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

The company entered into a third-party logistics agreement to engage a 3PL Agent to distribute the company’s products to its customers. The 3PL Agent provides services to the company that include storage, shipping and distribution, processing product returns, as well as customer service, order to cash, and logistics support. The company’s customers are currently limited to pharmaceutical specialty distributors and specialty pharmacy. The company primarily sells ANKTIVA to specialty distributors through a drop-ship arrangement under which orders from various healthcare institutions such as hospitals, medical facilities, physician practices, pharmacies and government agencies are processed through and controlled by specialty distributors. Under the drop-ship arrangement, the 3PL Agent ships the product to various health care institutions without the specialty distributor ever taking physical possession of the product. The company recognizes product revenue when ANKTIVA is delivered to the destination as instructed and controlled by specialty distributors.

The company also sells ANKTIVA directly to a specialty pharmacy who then subsequently distributes ANKTIVA to physicians, clinics, and certain medical centers, hospitals or other healthcare institutions. The company recognizes product revenue when ANKTIVA is delivered to the specialty pharmacy location.

Product revenue is recorded with each sale at wholesale acquisition cost, net of: (a) consideration payable to customers; and (b) variable considerations. The company pays fees to the specialty distributors for certain administrative services associated with the distribution of the product wherein the terms of which are also detailed in its contracts. Such fees are not for a distinct good or service and, accordingly, are recorded as a reduction of revenue, as well as a reduction of accounts receivable (trade discounts) or as a component of accrued expenses (distributor fees). The variable consideration components include, but are not limited to, prompt payment discounts, product returns, chargebacks, rebates, and co-payment assistance, which are collectively referred to as “Gross-to-Net Adjustments.” In accordance with ASC 606, the company must make significant judgments to determine the estimates for certain variable considerations. Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The company utilizes the expected value method when estimating the amount of variable consideration to include in the transaction price with respect to each of the foregoing variable consideration components. Where appropriate, these estimates are based on factors such as industry and forecasted customer buying and payment patterns, our experience, current contractual and statutory requirements, and specific known market events and trends.

148

Table of Contents

Variable considerations are reassessed each reporting period, and adjustments are recorded on a cumulative catch-up basis, which affects product revenue and net income in the period of adjustment. The actual amounts of variable consideration ultimately received may differ from our estimates. If actual results in future periods vary from our estimates, we adjust these estimates accordingly. As we gain more experience, estimates will be more heavily based on the expected utilization from historical data we have accumulated since the ANKTIVA product launch. The consideration payable to customers and contingent considerations reflect our best estimates of the amount of consideration to which we are entitled based on the terms of the contracts.

Other Revenues

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.

We sell our proprietary GMP-in-a-Box bioreactors and related consumables to affiliated companies and third parties. The arrangements typically include delivery of bioreactors, consumables, and providing installation service and perpetual software licenses for using the equipment. We recognize revenue when customers obtain control and can benefit from the promised goods or services, generally upon installation of the bioreactors, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. Upfront payments and fees are recorded as deferred revenue upon receipt and recognized as revenue when we satisfy our performance obligations under these arrangements.

Grant revenue is typically paid for reimbursable costs incurred over the duration of the associated research project or clinical trial and is recognized either when expenses reimbursable under the grants have been incurred and payments under the grants become contractually due or when cash is received, depending on the certainty of payment and other factors specific to each grant.

License Agreements with Third Parties

The company has nonexclusive license agreements with a limited number of pharmaceutical and biotechnology companies that grant them the right to use our cell lines and intellectual property for non-clinical use. These agreements generally include upfront fees and annual research license fees for such use, as well as commercial license fees for sales of the licensee products developed or manufactured using our intellectual property and cell lines.

Under our license agreements with customers, we typically promise to provide a license to use certain cell lines and related patents, the related know-how, and future research and development data that affect the license. We have concluded that these promises represent a single performance obligation due to the highly interrelated nature of the promises. We provide the cell lines and know-how immediately upon entering into the contracts. Research and development data are provided throughout the term of the contract when and if available. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation based on relative standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied.

Our license agreements may include non-refundable upfront payments, event-based milestone payments, sales-based royalty payments, or some combination of these. The event-based milestone payments represent variable consideration, and we use the most likely amount method to estimate this variable consideration. Given the high degree of uncertainty around the achievement of these milestones, we do not recognize revenue from these milestone payments until the uncertainty associated with these payments is resolved. We currently estimate variable consideration related to milestone payments to be zero and, as such, no revenue has been recognized for milestone payments. We recognize revenue from sales-based royalty payments when or as sales occur. On a quarterly basis, we re-evaluate our estimate of milestone variable consideration to determine whether any amount should be included in the transaction price and recorded in revenue prospectively.

Inventories

Inventory is stated at the lower of cost or net realizable value and consists of raw materials, work-in-progress and finished goods. Cost is determined using a standard cost method, which approximates actual cost, and assumes a FIFO flow of goods. Inventory that is used for clinical development purposes is expensed in research and development expense, on the consolidated statement of operations when consumed.

149

Table of Contents

Cost of sales consists primarily of third-party manufacturing costs, distribution, and overhead costs related to sales of approved product subsequent to receiving regulatory approval. Cost of sales may also include costs related to excess or obsolete inventory adjustment charges, abnormal costs, unabsorbed manufacturing and overhead costs, and manufacturing variances. All costs associated with the production of ANKTIVA prior to receiving regulatory approval were expensed in research and development expense, on the consolidated statement of operations in the period incurred and therefore are not reflected in cost of sales.

The work-in-progress materials consists of bulk drug substance and drug product, which have a multi-year shelf life. When the bulk drug substance is manufactured into ANKTIVA drug product, those goods have a shelf life of two years from the date of manufacture. During September 2024, the shelf life of ANKTIVA drug product was extended to three years. The work-in-progress drug product gets converted to finished goods at the time of labeling. Our expectation is to sell finished goods at least twelve months prior to expiration. Due to our long manufacturing lead time, it was necessary to build up inventory in support of ANKTIVA forecasted sales. As a result of being in the early stages of the ANKTIVA product launch, the company is continuing to evaluate the length of its operating cycle.

On a quarterly basis, the company analyzes its inventory levels for excess quantities and obsolescence (expiration), taking into account factors such as historical and anticipated future sales compared to quantities on hand and the remaining shelf life. As of December 31, 2024, we determined that a reserve related to ANKTIVA inventory for excess quantities and obsolescence was not required. In addition, since the FDA approval of ANKTIVA the company has not recorded any inventory write downs.

Revenue Interest Liability

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. In addition, Oberland may purchase additional Revenue Interests from us in exchange for the $100.0 million Second Payment upon satisfaction of certain conditions specified in the RIPA. Under the RIPA, Oberland has the right to receive quarterly payments from us based on, among other things, a certain percentage of our worldwide net sales, excluding those in China, during such quarter. The RIPA is considered a sale of future revenues and is accounted for 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 this liability may vary during the term of the agreement depending on a number of factors, including the level of actual and forecasted net sales. 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, interest expense, and the time period for repayment.

Derivative Liabilities

Embedded derivatives that are required to be bifurcated from the underlying debt instrument that do not meet the derivative scope exception and equity classification criteria are accounted for and valued as separate financial instruments. The terms of an embedded derivative related to a contingent exercisable prepayment feature of a convertible note have been evaluated and deemed to require bifurcation. This embedded derivative was initially measured at fair value and is remeasured to fair value at each reporting date until the derivative is settled. On December 10, 2024, the company and Nant Capital entered into a second amended and restated promissory note (the $505.0 million December 2024 Promissory Note) for which the FVO method of accounting was elected. As such, the bifurcation of the embedded derivative is not required. The embedded derivative is now included within the fair value of the second amended and restated promissory note recorded in related-party convertible note payable at fair value, on the consolidated balance sheet.

In addition, the RIPA contains certain features that meet the definition of being an embedded derivative requiring bifurcation as a separate compound financial instrument apart from the RIPA. The derivative liability is initially measured at fair value upon issuance and is subject to remeasurement at each reporting period with changes in fair value recognized in other income (expense), net, on the consolidated statement of operations.

Research and Development Costs

Major components of research and development costs include cash compensation and other personnel-related expenses, stock-based compensation, depreciation and amortization expense on research and development property and equipment and intangible assets, costs of preclinical studies, clinical trials costs, including CROs and related clinical manufacturing, including third-party CMOs, costs of drug development, costs of materials and supplies, facilities cost, overhead costs, regulatory and compliance costs, and fees paid to consultants and other entities that conduct certain research and development activities on our behalf. Costs incurred in research and development are expensed as incurred.

The company classifies its research and development expenses as either external or internal. The company’s external research and development expenses support its various preclinical and clinical programs. The company’s internal research and development expenses include payroll and benefits expenses, facilities and equipment expense, and other indirect research and development expenses incurred in support of its research and development activities. The company’s external and internal resources are not directly tied to any one research or drug discovery program and are typically deployed across multiple programs and are not allocated to specific product candidates or development programs.

Included in research and development costs are clinical trial and research expenses based on the services performed pursuant to contracts with research institutions and clinical research organizations and other vendors that conduct clinical trials and research on our behalf. We record accruals for estimated costs under these contracts. When evaluating the adequacy of the accrued liabilities, we analyze the progress of the preclinical studies or clinical trials, including the phase or completion of events, invoices received, contracted costs and purchase orders. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period based on the facts and circumstances known at that time. Although we do not expect the estimates to be materially different from the amounts actually incurred, if the estimates of the status and timing of services performed differ from the actual status and timing of services performed, we may report amounts that are too high or too low in any particular period. Actual results could differ from our estimates. We adjust the accruals in the period when actual costs become known.

Contingencies

We record accruals for loss contingencies to the extent that we conclude it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. We accrue for the best estimate of a loss within a range; however, if no estimate in the range is better than any other, then we accrue the minimum amount in the range. If we determine that a material loss is reasonably possible, we disclose the possible loss or range of loss, or that the amount of loss cannot be estimated at this time. We evaluate, on a quarterly basis, developments in legal proceedings and other matters that could cause a change in the potential amount of the liability recorded or the range of potential losses disclosed. Moreover, we record gain contingencies only when they are realizable and the amount is known. Additionally, we record our rights to insurance recoveries, limited to the extent of incurred or probable losses, as a receivable when such recoveries have been agreed to with our third-party insurers and when receipt is deemed probable. This includes instances when our third-party insurers have agreed to pay, on our behalf, certain legal defense costs and settlement amounts directly to applicable law firms and a settlement fund.

Warrants

The company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in FASB ASC Topic 480, Distinguishing Liabilities from Equity (ASC 480), and ASC 815. The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the company’s own stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For warrants that meet all criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital, on the consolidated statement of stockholders’ deficit at the time of issuance. For warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and on each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss in other income (expense), net, on the consolidated statement of operations. The fair value of the warrants was estimated using the Black-Scholes option pricing model.

Fair Value Option Election

The company elected to apply the FVO method of accounting in line with ASC 825 and account for certain of its notes and embedded derivatives at fair value as a single instrument in accordance with ASC 815. The notes for which the FVO is elected are recorded at fair value upon the date of issuance and subsequently remeasured to fair value at each reporting period. Changes in the fair value of the notes accounted for at fair value are recorded as a component of other income (expense), net, on the consolidated statement of operations. Any changes in fair value caused by instrument-specific credit risk are recorded separately in other comprehensive income (loss), on the consolidated statement of comprehensive loss. The cumulative amount previously recorded in other comprehensive income (loss) resulting from changes in the instrument-specific credit risk for extinguished notes are reclassified and reported in current earnings on the consolidated statement of operations. All costs associated with the issuance of the convertible promissory note accounted for using the FVO were expensed upon issuance.

The company has applied the FVO on the $505.0 million December 2024 Promissory Note and $30.0 million March 2023 Promissory Note prior to its extinguishment on December 29, 2023. See Note 12 “Related-Party Debt” for more information. During the year ended December 31, 2024, the company recorded $1.2 million changes in fair value related to instrument-specific credit risk.

Debt Modification and Extinguishment

The company evaluates amendments to its debt instruments in accordance with ASC 470-50. This evaluation includes comparing (1) if applicable, the net present value of future cash flows of the amended debt to that of the original debt and (2) the change in fair value of an embedded conversion feature to that of the carrying amount of the debt immediately prior to amendment to determine, in each case, if a change greater than 10% occurred. In instances where the net present value of future cash flows or the fair value of an embedded conversion feature, if any, changed more than 10%, the company applies extinguishment accounting. In instances where the net present value of future cash flows and the fair value of an embedded conversion feature, if any, changed less than 10%, the company accounts for the amendment to the debt as a debt modification. Gains and losses on debt amendments that are considered extinguishments are recognized in current earnings or in additional paid-in capital if the transactions are with entities under common control. Debt amendments that are considered debt modifications are accounted for prospectively through yield adjustments, based on the revised terms. The increase in fair value of the embedded conversion feature from the debt modification was accounted for as an increase in debt discount with a corresponding increase in additional paid-in capital. Legal fees and other costs incurred with third parties that are directly related to debt modifications are expensed as incurred. Amounts paid by the company to the lenders, are reflected as additional debt discount and amortized as an adjustment of interest expense over remaining term of modified debt using the effective interest rate method.

Provision for Income Taxes

Our provision for income taxes is computed under the asset and liability method. Significant estimates are required in determining our provision for income taxes. Some of these estimates are based on interpretations of existing tax laws or regulations. We recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined on the basis of the difference between the tax basis of assets and liabilities and their respective financial reporting amounts (temporary differences) at enacted tax rates in effect for the years in which the differences are expected to reverse. A valuation allowance is established for deferred tax assets for which it is more likely than not that some portion or all of the deferred tax assets, including net operating losses and tax credits, will not be realized. We periodically re-assess the need for a valuation allowance against our deferred tax assets based on various factors including our historical earnings experience by taxing jurisdiction, and forecasts of future operating results and utilization of net operating losses and tax credits prior to their expiration. Significant judgment is required in making this assessment and, to the extent that a reversal of any portion of our valuation allowance against our deferred tax assets is deemed appropriate, a tax benefit will be recognized against our provision for income taxes in the period of such reversal.

Stock-Based Compensation

We account for stock-based compensation under the provisions of FASB ASC Topic 718, Compensation—Stock Compensation (ASC 718). We estimate fair value of each stock option award on the date of grant using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the use of subjective assumptions, including, but not limited to, expected stock price volatility over the term of the awards and the expected term of the stock options. We measure the fair value of an equity-classified award at the grant date and recognize the stock-based compensation expense over the period of vesting on the straight-line basis for our outstanding share awards that do not contain a performance condition. For awards subject to performance-based vesting conditions, we assess the probability of the individual milestones under the award being achieved and stock-based compensation expense is recognized over the service period using the graded vesting method once management believes the performance criteria is probable of being met. For awards with service or performance conditions, we recognize the effect of forfeitures in compensation cost in the period that the award was forfeited.

Recent Accounting Pronouncements

Other Company Information

Transition from Smaller Reporting Company Status

On December 31, 2024, we ceased to be a “smaller reporting company” because the market value of our common stock held by non-affiliates exceeded $700.0 million as of June 28, 2024. However, we are complying with certain scaled disclosure requirements available to smaller reporting companies in this Annual Report (including as incorporated by reference to the information contained in our Proxy Statement), which we are permitted to do under SEC rules because we were a smaller reporting company in 2024. As a result, the information that we provide to our stockholders may be different than what you might receive from other public reporting companies in which you hold equity interests.

ITEM 7.     MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion and analysis of our financial condition and results of operations should be read together with the description of our business that appears in Part I, Item 1. “Business” and the consolidated financial statements and related notes thereto in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. This discussion contains forward-looking statements as a result of many factors, including those set forth under Part I, Item 1. “Business—Forward-Looking Statements” and Item 1A. “Risk Factors,” and elsewhere in this Annual Report. These statements are based on our management’s beliefs and assumptions and on information currently available to our management. Actual results could differ materially from those discussed in or implied by such forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Annual Report, particularly in Part I, Item 1A. “Risk Factors.” Except as required by law, we do not undertake any responsibility to update any of these factors or to announce publicly any revisions to any of the forward-looking statements contained in this or any document, whether as a result of new information, future events, or otherwise.

Our Business

We are an integrated clinical-stage biotechnology company discovering, developing, and commercializing next-generation immuno- and cellular therapies that bolster the natural immune system to drive and sustain an immune response. Using our proprietary platforms that amplify both the innate and adaptive branches of the immune system, our teams of clinical, scientific, and manufacturing experts, advance novel therapies and vaccines aimed at defeating urologic and other cancers, as well as infectious diseases. Although such designations may not lead to a faster development process or regulatory review and may not increase the likelihood that a product candidate will receive approval, N-803 (Anktiva), our lead biologic commercial product candidate, has received Breakthrough Therapy and Fast Track designations and is currently under review by the FDA for treatment in combination with BCG of patients with BCG-unresponsive NMIBC with CIS with or without Ta or T1 disease and has a new user fee goal date (PDUFA date) of April 23, 2024.

Our platforms and their associated product candidates are designed to attack cancer and infectious pathogens by activating both the innate immune system, including—NK cells, dendritic cells, and macrophages, as well as—the adaptive immune system comprising—B and T cells,—in an orchestrated manner. The goal of this potentially best-in-class approach is to generate immunogenic cell death thereby eliminating rogue cells from the body whether they are cancerous or virally-infected. Our ultimate goal is to overcome the limitations of current treatments, such as checkpoint inhibitors, and/or reduce the need for standard high-dose chemotherapy in cancer by employing this coordinated approach to establish “immunological memory” that confers long-term benefit for the patient.

Our proprietary platforms for the development of biologic product candidates include: (i) antibody-cytokine fusion proteins, (ii) DNA, RNA, and recombinant protein vaccines, and (iii) cell therapies. These platforms have generated 9 novel therapeutic agents for which clinical trials are either underway or planned in solid and liquid tumors. Specifically, our clinical focus includes bladder, lung, and colorectal cancers and GBM, which are among the most frequent and lethal cancer types, and where there are high failure rates for existing standards of care or no available effective treatment.

Our lead biologic commercial product candidate Anktiva is an IL-15 superagonist antibody-cytokine fusion protein. In May 2022, we announced the submission of a BLA to the FDA for Anktiva in combination with BCG for the treatment of patients with BCG-unresponsive NMIBC with CIS with or without Ta or T1 disease. 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. Satisfactory resolution of the observations noted at the pre-license inspection would be required before the BLA could be approved. At the time, the FDA further provided recommendations specific to additional CMC issues and assays to be resolved. The CRL did not request new preclinical studies or Phase III clinical trials to evaluate safety or efficacy. The FDA requested that the company provide updated duration of response data for the efficacy population as identified by the FDA in the company’s resubmission, as well as a safety update.

Table of Contents

On October 23, 2023, we announced that we had completed the resubmission of the BLA addressing the issues in the CRL. As part of our resubmission, we provided an update of the duration of response regarding the responders identified by the FDA in the efficacy population for BCG unresponsive subjects with high-risk CIS disease. On October 26, 2023, we announced that the FDA had accepted our BLA resubmission for review and considered it as a complete response to the CRL. The FDA has set a new user fee goal date (PDUFA date) of April 23, 2024. While we believe the BLA resubmission addresses the issues identified in the CRL, there is no guarantee that the FDA will ultimately agree that such issues have been successfully addressed and resolved. It is unclear when the FDA will approve our BLA, if at all.

Further late-stage efforts for Anktiva are in development within the broader bladder cancer space, including BCG-naïve NMIBC. In addition, data from multiple clinical trials suggests N-803 has potential to enhance the activity of therapeutic mAbs, including checkpoint inhibitors (e.g., pembrolizumab/Keytruda), across a wide range of tumor types. We believe there is potential for N-803 to become a therapeutic foundation across all phases of treatment, including in adjunctive therapy, to amplify, reactivate or extend the efficacy of standard of care. In addition to N-803, we have active clinical programs evaluating therapeutic candidates from our DNA and RNA vaccine technology platforms and our NK cell-based therapy platforms in oncology and infectious disease indications.

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, Oberland may purchase additional Revenue Interests from us in exchange for the $100.0 million Second Payment upon satisfaction of certain conditions specified in the RIPA, including following the receipt of approval by the FDA of the company’s BLA for N-803 in combination with BCG for the treatment of patients with BCG-unresponsive NMIBC with CIS with or without Ta or T1 disease on or before June 30, 2024. Under the RIPA, Oberland has the right to receive quarterly payments from us based on, among other things, a certain percentage of our worldwide net sales, excluding those in China, during such quarter.

Also, on December 29, 2023 and in connection with the RIPA, we entered into an SPOA with Oberland pursuant to which we sold an aggregate of approximately $10.0 million of our common stock at $4.1103 per share in a private placement. Oberland also has an option to purchase up to an additional $10.0 million of our common stock, at a price per share to be determined by reference to the 30-day trailing volume weighted-average price of our common stock calculated from the date of exercise.

The Merger

On December 21, 2020, NantKwest and NantCell entered into the Merger Agreement, pursuant to which NantKwest and NantCell agreed to combine their businesses. The Merger Agreement provided that a wholly-owned subsidiary of the company would merge with and into NantCell, with NantCell surviving the Merger as a wholly-owned subsidiary of the company.

On March 9, 2021, we completed the Merger pursuant to the terms of the Merger Agreement. Under the terms of the Merger Agreement, at the effective time of the Merger (the Effective Time), each share of NantCell common stock, par value $0.001 per share, issued and outstanding immediately prior to the Effective Time, subject to certain exceptions as set forth in the Merger Agreement, was converted automatically using the Exchange Ratio into newly issued shares of Company Common Stock, with cash paid in lieu of any fractional shares. At the Effective Time, each share of the company’s common stock issued and outstanding immediately prior to the Effective Time, remained an issued and outstanding share of the combined company. At the Effective Time, each outstanding option, RSU or warrant to purchase NantCell common stock was converted using the Exchange Ratio into an option, RSU or warrant, respectively, on the same terms and conditions immediately prior to the Effective Time, to purchase shares of Company Common Stock.

Immediately following the Effective Time, the former stockholders of NantCell held approximately 71.5% of the outstanding shares of Company Common Stock and the stockholders of NantKwest as of immediately prior to the Merger held approximately 28.5% of the outstanding shares of Company Common Stock. As a result of the Merger and immediately following the Effective Time, Dr. Patrick Soon-Shiong, our Executive Chairman and Global Chief Scientific and Medical Officer, and his affiliates beneficially owned, in the aggregate, approximately 81.8% of the outstanding shares of Company Common Stock. Following the consummation of the Merger, the symbol for shares of the company’s common stock was changed to “IBRX.”

Table of Contents

During the year ended December 31, 2021, we recorded $13.0 million of costs in connection with the Merger consisting of financial advisory, legal and other professional fees.

Accounting Treatment of the Merger

The Merger represents a business combination pursuant to FASB ASC Topic 805-50, Mergers (ASC 805-50), which was accounted for as a transaction between entities under common control as Dr. Soon‑Shiong and his affiliates were the controlling stockholders of both the company and NantCell for all of the periods presented in this report. As a result, all of the assets and liabilities of NantCell were combined with ours at their historical carrying amounts on the closing date of the Merger. We recast our prior period financial statements for the year ended December 31, 2021 to reflect the conveyance of NantCell’s common shares as if the Merger had occurred as of the earliest date of the consolidated financial statements presented in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. All material intercompany accounts and transactions have been eliminated in consolidation.

COVID-19 Pandemic

The COVID-19 pandemic continues to present a public health and economic challenge around the world. Through the date of this Annual Report, we have not seen a material adverse impact to our business from the pandemic. However, given the continuously evolving nature of the pandemic, we cannot at this time predict the specific extent, duration, or full impact that this pandemic may have on our financial condition and results of operations, including ongoing and planned clinical trials. More specifically, the pandemic may result in prolonged impacts that we cannot predict at this time and we expect that such uncertainties will continue to exist for the foreseeable future.

We continue to monitor the impact of COVID-19 on our business, including our clinical trials, manufacturing facilities and capabilities, and ability to access necessary resources. For a discussion of the risks presented by the COVID-19 pandemic to our results of operations and financial condition, see Part I, Item 1A. “Risk Factors.”

Operating Results

From inception through the date of this Annual Report, we have generated minimal revenue from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables, and grant programs. We have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development. We have incurred net losses in each year since our inception and, as of December 31, 2023, we had an accumulated deficit of $3.0 billion. During the years ended December 31, 2023, 2022 and 2021, net losses attributable to ImmunityBio common stockholders were $583.2 million, $416.6 million, and $346.8 million, respectively. Substantially all of our net losses resulted principally from costs incurred in connection with our ongoing clinical trials and operations, our research and development programs, and from selling, general and administrative costs associated with our operations, including stock-based compensation expense.

As of December 31, 2023, we had 628 employees. Personnel of related companies who provide corporate, general and administrative, certain research and development, and other support services under our shared services agreement with NantWorks are not included in this number. See Note 11, Related-Party Agreements, 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. In anticipation of the commercialization of select drug candidates, we expect to continue to incur significant expenses and increasing operating losses for the foreseeable future, which may fluctuate significantly from quarter-to-quarter and year-to-year. See “—Future Funding Requirements” below for a discussion of our anticipated expenditures and sources of capital we expect to access to fund these expenditures.

Collaboration Agreements

We anticipate that strategic collaborations will continue to be an integral part of our operations, providing opportunities to leverage our partners’ expertise and capabilities to gain access to new technologies and further expand the potential of our technologies and product candidates across relevant platforms. We believe we are well positioned to become a leader in immunotherapy due to our broad and vertically-integrated platforms and through complementary strategic partnerships.

115

Table of Contents

We believe that our innovative approach to orchestrate and combine therapies for optimal immune system response will become a therapeutic foundation across multiple indications. Additionally, we believe that data from multiple clinical trials indicates N-803 has broad potential to enhance the activity of therapeutic mAbs, including checkpoint inhibitors, across a wide range of tumor types. We may also enter into supply arrangements for various investigational agents to be used in our clinical trials. See Note 6, Collaboration and License Agreements and Acquisition, 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 regarding our collaboration and license agreements.

Agreements with Related Parties

Our Executive Chairman, Global Chief Scientific and Medical Officer and principal stockholder, founded and has a controlling interest in NantWorks, which is a collection of companies in the healthcare and technology space. We have entered into arrangements with NantWorks, and certain affiliates of NantWorks. Affiliates of NantWorks are also affiliates of the company due to the common control by and/or common ownership interest of our Executive Chairman and Global Chief Scientific and Medical Officer.

Related-Party Debt

The following discussion of the company’s related-party promissory notes does not purport to be complete and is qualified in its entirety by reference to the full text of the notes, copies of which are incorporated by reference in Part IV, Item 15. “Exhibits and Financial Statement Schedules” of this Annual Report.

Related-Party Convertible Promissory Notes

On September 11, 2023, the company entered into a stock purchase agreement with Nant Capital, NantMobile and NCSC (collectively, the “related-party purchasers”), which are entities affiliated with Dr. Soon-Shiong, pursuant to which the related-party purchasers exchanged outstanding fixed-rate promissory notes held by such related-party purchasers, representing approximately $270.0 million in aggregate principal amount and accrued and unpaid interest, in exchange for an aggregate of 209,291,936 shares of common stock at an exchange price of $1.29 per share. As a result of the exchange, the company is forever released and discharged from all its obligations and liabilities under these notes.

On September 11, 2023, the company executed a $200.0 million convertible promissory note with Nant Capital. The note bears interest at Term SOFR plus 8.0% per annum. The accrued interest shall be payable monthly commencing on September 30, 2023. The outstanding principal amount and any accrued and unpaid interest are due on the earlier of (i) September 11, 2026 or (ii) upon the occurrence and during the continuance of an “event of default” (as defined in the note). We may prepay the outstanding principal amount, together with any accrued interest, at any time, in whole or in part, without premium or penalty upon five (5) days’ written notice to the noteholder. The noteholder has the sole option to convert all (but not less than all) of the outstanding principal amount and accrued but unpaid interest into shares of the company’s common stock at a conversion price of $1.9350 per share. We received net proceeds of approximately $199.0 million from this financing, net of a $1.0 million origination fee paid to the noteholder. On December 29, 2023 in connection with the RIPA, the company and Nant Capital entered into a letter amendment whereby this promissory note became subordinated to the RIPA payment obligations.

Related-Party Convertible Note at Fair Value

On March 31, 2023, the company executed a $30.0 million promissory note with Nant Capital. This note bears interest at Term SOFR plus 8.0% per annum. The outstanding principal amount and any accrued and unpaid interest are due on the earlier of December 31, 2023 or upon the occurrence and continuation of an event of default (as defined in the note). The interest on this note is paid on a quarterly basis beginning on June 30, 2023. The company may prepay the outstanding principal amount and any accrued and unpaid interest of the promissory note, at any time, in whole or in part, without penalty. Upon receipt of a written notice of prepayment from the company, the noteholder has the right, at its option, to convert the outstanding principal amount to be prepaid and the accrued and unpaid interest thereon (as specified in the notice of prepayment) into shares of the company’s common stock at a price of $2.28 per share. Additionally, the whole promissory note and any accrued interest may be converted into shares of the company’s common stock at a conversion price of $2.28 per share (subject to appropriate adjustment from time to time for any stock dividend, stock split, combination of shares, reorganization, recapitalization, reclassification or other similar event), at the option of the noteholder.

Table of Contents

The company received net proceeds of approximately $29.9 million from this financing, net of a $0.1 million origination fee paid to the noteholder, which we used, together with other available funds, to progress our pre-commercialization efforts and clinical development programs, to fund other research and development activities, for capital expenditures, and for other general corporate purposes.

On September 11, 2023, the company and Nant Capital entered into a letter agreement pursuant to which the maturity date of this promissory note was extended from December 31, 2023 to December 31, 2024. On December 29, 2023 in connection with the RIPA, the company and Nant Capital entered into a letter amendment pursuant to which the maturity date of this promissory note was extended to December 31, 2025, and the note became subordinated to the RIPA payment obligations.

This note was accounted for under the ASC 825-10-15-4 FVO election until it was amended on December 29, 2023. Under the FVO election, the note was initially measured at its issuance date estimated fair value and subsequently remeasured at estimated fair value on a recurring basis at each reporting period date. With each such remeasurement, the note was adjusted to fair value, with the change in fair value recorded in other expense, net, on the consolidated statement of operations.

On June 13, 2023, the company executed a $30.0 million promissory note with Nant Capital. The company was able to request up to three (3) advances of $10.0 million each pursuant to the note. The principal amount of each advance bears interest at Term SOFR plus 8.0% per annum. The accrued interest on any advance is payable quarterly on the last business day of June, September and December. The outstanding principal amount and any accrued and unpaid interest on advances were due on the earlier of (i) December 31, 2023 or (ii) upon the occurrence and during the continuance of an event of default (as defined in the note). We may prepay the outstanding principal amount, together with any accrued interest, on any then-outstanding advances, at any time, in whole or in part, without premium or penalty, and without the prior consent of the noteholder, upon five (5) days written notice to the noteholder.

The company received net proceeds of approximately $29.9 million from this financing, net of a $0.1 million origination fee paid to Nant Capital, which we used, together with other available funds, to progress our regulatory approval efforts, pre-commercialization activities and clinical development programs, to fund other research and development activities, for capital expenditures, and for other general corporate purposes.

On September 11, 2023, the company and Nant Capital entered into a series of letter agreements pursuant to which the maturity date of related-party nonconvertible promissory notes totaling $505.0 million in principal were extended from December 31, 2023 to December 31, 2024.

On December 29, 2023 in connection with the RIPA, the company and Nant Capital entered into an amended and restated promissory note pursuant to which the existing $30.0 million promissory note, along with other existing related-party nonconvertible promissory notes, was amended to be included in the Tranche 2 principal amount of the amended $505.0 million December 2023 promissory note. The Tranche 2 of the promissory note has a principal amount of $380.0 million, a maturity date of December 31, 2025, and an interest rate of Term SOFR plus 7.5% per annum. Based on the terms of the amended and restated promissory note, the noteholder, at its sole discretion, may convert all of the $380.0 million principal amount into shares of common stock at a conversion price of $8.2690 per share. The new note became subordinated to the RIPA payment obligations.

Immuno-Oncology Clinic, Inc.

We have entered into multiple agreements with the Clinic to conduct clinical trials related to certain of our product candidates. The Clinic is a related party as it is owned by an officer of the company and NantWorks manages the administrative operations of the Clinic.

117

Table of Contents

In 2021, we completed a review of alternative structures that could support our more complex clinical trial requirements and made a decision to explore a potential transition of clinical trials at the Clinic to a new structure (including contracting with a new, non-affiliated professional corporation) to be determined and agreed upon by all parties. While we have not yet finalized the potential transition, we continue discussions with potential partners around such alternative structures. During the years ended December 31, 2023, 2022 and 2021, we recorded $2.2 million, $2.4 million and $1.6 million, respectively, in research and development expense, on the consolidated statements of operations related to clinical trial and transition services provided by the Clinic.

Components of our Results of Operations

Revenue

From inception through the date of this Annual Report, we have generated minimal revenue from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables, and grant programs. We have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development. If we fail to complete the development of our product candidates in a timely manner or fail to obtain regulatory approval for them, we may never be able to generate substantial future revenue.

Operating Expenses

We generally classify our operating expenses into research and development, and selling, general and administrative expenses. Personnel costs, including salaries, benefits, bonuses, and stock-based compensation expense comprise a significant component of our research and development, and selling, general and administrative expense categories. We allocate expenses associated with our facilities and information technology costs between these two categories, primarily based on the nature of each cost.

Research and Development

Research and development expense consists of expenses incurred while performing research and development activities to discover and develop our technology and product candidates. This includes conducting preclinical studies and clinical trials, manufacturing development efforts and activities related to regulatory submissions for product candidates. We recognize research and development expenses as they are incurred.

118

Table of Contents

Our research and development expenses primarily consist of:

•clinical trial and regulatory-related costs;

•expenses incurred under agreements with investigative sites and consultants that conduct our clinical trials;

•expenses incurred under collaborative agreements;

•manufacturing and testing costs and related supplies and materials;

•employee-related expenses, including salaries, benefits, travel and stock-based compensation; and

•facility expenses dedicated to research and development.

The company classifies its research and development expenses as either external or internal. The company’s external research and development expenses support its various preclinical and clinical programs. The company’s internal research and development expenses include payroll and benefits expenses, facilities and equipment expense, and other indirect research and development expenses incurred in support of its research and development activities. The company’s external and internal resources are not directly tied to any one research or drug discovery program and are typically deployed across multiple programs and are not allocated to specific product candidates or development programs.

We expect our research and development expenses to increase significantly for the foreseeable future as we continue to invest in research and development activities related to developing our product candidates and conducting our ongoing and planned clinical trials.

The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. The successful development of product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs required to complete the remaining development of any product candidates. This is due to the numerous risks and uncertainties associated with the development of product candidates.

The costs of clinical trials may vary significantly over the life of a project owing to, but not limited to, the following:

•per patient trial costs;

•the number of sites included in the clinical trials;

•the countries in which the clinical trials are conducted;

•the length of time required to enroll eligible patients;

•the number of patients that participate in the clinical trials;

•the number of doses that patients receive;

•the cost of comparative agents used in clinical trials;

•the drop-out or discontinuation rates of patients;

•potential additional safety monitoring or other studies requested by regulatory agencies;

•the duration of patient follow-up; and

•the safety profile and efficacy of the product candidate.

We have only one product candidate, Anktiva in combination with BCG for the treatment of patients with BCG-unresponsive NMIBC with CIS with or without Ta or T1 disease, for which we submitted a BLA to the FDA in May 2022. 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. On October 23, 2023, we announced that we had completed the resubmission of the BLA addressing the issues in the CRL. On October 26, 2023, we announced that the FDA had accepted our BLA resubmission for review and considered it as a

119

Table of Contents

complete response to the CRL. The FDA has set a new user fee goal date (PDUFA date) of April 23, 2024. There can be no assurance that our product candidate will be approved for commercial sale by the FDA in the near term, if ever. We do not expect any of our other product candidates to be commercially available for the foreseeable future, if ever.

Selling, General and Administrative

Selling, general and administrative expense consists primarily of salaries and personnel-related costs, including employee benefits and any stock-based compensation, for employees performing functions other than research and development. This includes personnel in executive, finance, human resources, information technology, legal, and administrative support functions. Other selling, general and administrative expenses include facility-related costs not otherwise allocated to research and development expense, professional fees for auditing, tax and legal services, advertising costs, expenses associated with strategic business transactions and business development efforts, obtaining and maintaining patents, consulting costs, royalties and licensing costs, and costs of our information systems.

We expect that our selling, general and administrative expense will increase for the foreseeable future as we expand operations, build out information systems and increase our headcount to support continued research activities and the development of our clinical programs. We have incurred and expect that we will continue to incur in the future, additional costs associated with operating as a public company, including costs to comply with stock exchange listing and SEC requirements, future funding efforts, corporate governance, internal controls, investor relations, disclosure and similar requirements applicable to public companies. Additionally, if and when we believe that a regulatory approval of a product candidate appears likely, we expect to incur significant increases in our selling, general and administrative expense relating to the sales and marketing of the approved product candidate.

Other Expense, Net

Other expense, net consists primarily of interest and investment income, interest expense (including amortization of debt discounts), unrealized gains and losses from investments in equity securities and equity-method investments, changes in fair value of warrants, derivative liabilities, and a convertible note, realized gains and losses on debt and equity securities, and gains and losses on foreign currency transactions.

Income Taxes

We are subject to U.S. federal income tax, as well as income tax in Italy, South Korea, California and other states. From inception through December 31, 2023, we have not been required to pay U.S. federal and state income taxes because of current and accumulated NOLs.

Discussion of Consolidated Results of Operations

Comparison of the Years Ended December 31, 2023 and 2022

Revenue

Revenue increased $0.4 million during the year ended December 31, 2023, as compared to the year ended December 31, 2022. The increase was primarily driven by higher grant revenue received in 2023.

Research and Development Expense

Research and development expense decreased $15.8 million during the year ended December 31, 2023, as compared to the year ended December 31, 2022. The following table summarizes our research and development expenses during the years ended December 31, 2023 and 2022, together with the changes in those items (in thousands):

121

Table of Contents

Research and development expense decreased $15.8 million primarily attributable to the following:

•A $5.1 million increase in external research and development expenses that was primarily due to higher qualification and testing costs, pre-licensing inspection costs, and outside consulting fees relating to regulatory and compliance services for the resubmission of the BLA, partially offset by a decrease in clinical trial costs and initial BLA submission fees;

•A $7.3 million decrease in personnel-related costs that was primarily due to the write off of accrued discretionary bonuses for 2022 not paid and a reduction in headcount, partially offset by an increase in stock-based compensation costs associated with new retention awards granted to existing employees;

•A $2.1 million decrease in equipment, depreciation, and facility costs that was primarily due to a reduction in activities related to facility expansion that occurred in the prior year, which resulted in lower expenditures for equipment qualification and certification, as well as lower expenses for sanitary services, partially offset by higher equipment maintenance costs; and

•An $11.5 million decrease in other research and development costs, primarily attributable to reductions in laboratory and test supplies and material supplies used for internal manufacturing, and no impairment costs from long-lived assets in the current year compared to the prior year, as well as an increase in collaboration costs allocated to a joint venture. Additionally, the write down of right-of-use assets from a lease used for R&D contributed to an additional decrease in other R&D expenses. The reduction in costs were partially offset by higher R&D activities and increased costs related to R&D licenses.

We expect our research and development expenses to increase significantly for the foreseeable future as we continue to invest in research and development activities related to developing our product candidates and conducting our ongoing and planned clinical trials.

Selling, General and Administrative Expense

Selling, general and administrative expense increased $26.9 million during the year ended December 31, 2023, as compared to the year ended December 31, 2022. The rise in expenses was primarily due to a $28.9 million increase in legal expenses, which was driven by higher defense costs and general legal services, as well as fewer legal insurance reimbursements received compared to the prior year. Additionally, there was a $1.1 million increase in personnel-related costs resulting from higher stock-based compensation expenses and travel costs, a $0.6 million increase in IT and security license fees, and a $0.2 million increase in marketing costs for pre-commercialization activities. These increases were partially offset by a $2.7 million reduction in consulting services from ERP implementations and professional fees from accounting and tax services, and a $1.2 million reduction in insurance expenses and other operating costs.

Impairment of Intangible Assets

Impairment of intangible assets increased $0.2 million during the year ended December 31, 2023, compared to the year ended December 31, 2022, due to an impairment charge of $0.9 million related to indefinite-lived intangible assets associated with the Tarmogen platform as the research and development program was limited in the current year. The $0.7 million write off of the organized workforce with definite lives during 2022 was as a result of the workforce reduction at the Dunkirk Facility.

Other Expense, Net

Other expense, net increased $155.7 million during the year ended December 31, 2023, as compared to the year ended December 31, 2022, due to a $65.7 million increase in interest expense driven by higher related-party borrowings, an increase in the Term SOFR rate, and higher amortization of related-party notes discounts. Additionally, there was a total increase in expense of $97.3 million driven by the change in the fair value of warrant liabilities and the change in the fair value of a related-party convertible note, and a $1.5 million increase in expense due to higher issuance costs associated with our registered direct offerings, and an increase in other expenses. These changes were partially offset by a $4.6 million lower loss on equity method investments and a $4.2 million increase in investment income.

Comparison of the Years Ended December 31, 2022 to 2021

See Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations” of our Annual Report filed with the SEC on March 1, 2023 for a discussion of the company’s results of operations during the year ended December 31, 2022 compared to the year ended December 31, 2021.

Financial Condition, Liquidity and Capital Resources

Sources of Liquidity

Since our inception, we have funded our operations primarily through proceeds from the issuance of related-party promissory notes and sales of our common stock under the ATM and our shelf registration statement, and through registered direct offerings.

On December 29, 2023, we entered into the RIPA to support the commercialization of Anktiva for the treatment of BCG-unresponsive NMIBC with CIS with or without Ta or T1 disease, the further development of our other product platforms, and to provide for other working capital needs.

Cash and Marketable Securities on Hand

As of December 31, 2023, we had cash and cash equivalents, and marketable securities of $267.4 million compared to $108.0 million as of December 31, 2022. We have typically invested our cash in a variety of financial instruments and classified these investments as available-for-sale. 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 risks. The general condition of the financial markets and the economy may increase those risks and may affect the value and liquidity of investments and restrict our ability to access the capital markets.

Proceeds from the ATM

During the year ended December 31, 2023, we received net proceeds of approximately $16.1 million from the issuance of 5,605,323 shares under the ATM. We used the net proceeds from this offering, together with other available funds, to progress our regulatory approval efforts, pre-commercialization activities and clinical development programs, to fund other research and development activities, for capital expenditures, and for other general corporate purposes. As of December 31, 2023, we had $208.8 million available for future stock issuances under the ATM.

Shelf Registration Statement

During February 2023, we filed a $750.0 million shelf registration statement with the SEC on Form S-3 for the offering and sale of equity and equity-linked securities, including common stock, preferred stock, debt securities, depositary shares, warrants to purchase common stock, preferred stock or debt securities, subscription rights, purchase contracts, and units. During the year ended December 31, 2023, we sold shares of our common stock and warrants valued at $184.4 million under the shelf. As of December 31, 2023, we had $565.6 million available for use under the shelf. This available shelf is in addition to the ATM.

Proceeds from Registered Direct Offerings

On February 15, 2023, we entered into a securities purchase agreement with certain institutional investors for the purchase and sale of 14,072,615 shares of our common stock, as well as warrants (the February 2023 Warrants) that allow such investors to purchase an additional 14,072,615 shares of common stock at an exercise price of $4.2636 per share, for a purchase price of $3.5530 per share and accompanying warrant. This transaction generated net proceeds of approximately $47.0 million, after deducting placement agent fees and other offering costs. Pursuant to the terms of a letter agreement dated July 25, 2023, the company and the investors agreed to reduce the exercise price of the outstanding February 2023 Warrants from $4.2636 per share to $3.2946 per share and extend the expiration date of the warrants until July 24, 2026.

On July 20, 2023, we entered into a securities purchase agreement with certain institutional investors for the purchase and sale of 14,569,296 shares of our common stock, as well as warrants that allow such investors to purchase an additional 14,569,296 shares of common stock at an exercise price of $3.2946 per share, for a purchase price of $2.7455 per share and accompanying warrant. This transaction generated net proceeds of approximately $37.5 million, after deducting placement agent fees and other offering costs.

We used the net proceeds from these registered direct offerings, together with other available funds, to progress our regulatory approval efforts, pre-commercialization activities and clinical development programs, to fund other research and development activities, for capital expenditures, and for other general corporate purposes.

Related-Party Promissory Notes

On September 11, 2023, the company entered into a stock purchase agreement with Nant Capital, NantMobile and NCSC pursuant to which the noteholders exchanged promissory notes totaling approximately $270.0 million in aggregate principal amount and accrued and unpaid interest for an aggregate of 209,291,936 shares of common stock at an exchange price of $1.29 per share. As a result of the exchange, the company was forever released and discharged from all its obligations and liabilities under the notes.

On September 11, 2023, the company and Nant Capital entered into a series of letter agreements pursuant to which the maturity date of the related-party nonconvertible notes described above totaling $505.0 million in principal was extended from December 31, 2023 to December 31, 2024. In addition, the company entered into a $200.0 million September 2023 promissory note with Nant Capital.

On December 29, 2023 in connection with the RIPA, the company and Nant Capital entered into an amended and restated promissory note and a letter amendment for the following outstanding promissory notes. Pursuant to the terms of the amended and restated promissory note, the amended $505.0 million December 2023 promissory note is comprised of a Tranche 1 principal amount of $125.0 million, which was previously the $125.0 million August 2022 promissory note before amendment, and a Tranche 2 with principal amount of $380.0 million, which is made up of the previous $300.0 million December 2021 promissory note, $50.0 million December 2022 promissory note, and $30.0 million June 2023 promissory note. In addition, the amendment allows Nant Capital, in its sole discretion, to convert all the Tranche 2 principal amount of $380.0 million of the amended promissory note into shares of the company’s common stock. The conversion price was determined subsequently at $8.2690 per share based on the agreement. The maturity date of the amended promissory note is December 31, 2025. Pursuant to the terms of the letter amendment, the maturity date of the $30.0 million March 2023 promissory note was extended from December 31, 2024 to December 31, 2025. Also, in connection with the RIPA transaction, all outstanding related-party promissory notes became subordinated to the RIPA payment obligations. After the amendment, the interest rates for the Tranche 1 principal amount and Tranche 2 principal amount of the $505.0 million December 2023 promissory note were Term SOFR plus 8.0% and Term SOFR plus 7.5%, respectively.

See Note 10, Related-Party Debt, 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 regarding our related-party debt.

Revenue Interest Purchase Agreement

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, Oberland may purchase additional Revenue Interests from us in exchange for the $100.0 million Second Payment upon satisfaction of certain conditions specified in the RIPA, including following the receipt of approval by the FDA of the company’s BLA for N-803 in combination with BCG for the treatment of patients with BCG-unresponsive NMIBC with CIS with or without Ta or T1 disease on or before June 30, 2024. Under the RIPA, Oberland has the right to receive quarterly payments from us based on, among other things, a certain percentage of our worldwide net sales, excluding those in China, during such quarter.

Also, on December 29, 2023 and in connection with the RIPA, we entered into an SPOA with Oberland pursuant to which we sold an aggregate of approximately $10.0 million of our common stock at $4.1103 per share in a private placement. Oberland also has an option to purchase up to an additional $10.0 million of our common stock, at a price per share to be determined by reference to the 30-day trailing volume weighted-average price of our common stock calculated from the date of exercise.

For more information, see Note 9, 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.

Table of Contents

Uses of Liquidity

In addition to the cash used to fund our operating activities discussed in “—Future Funding Requirements” below, we will require cash to settle the following obligations:

•As of December 31, 2023, our indebtedness payable at maturity totaled $735.0 million (excluding unamortized related-party notes discounts), held by entities affiliated with Dr. Soon-Shiong. In connection with the RIPA, all of our related-party promissory notes are now general unsecured obligations of the company that are subordinated in right of payment to indebtedness, obligations and other liabilities under the RIPA, the Revenue Interests issued pursuant to such agreement, and refinancing of the foregoing. In addition, the terms of promissory notes totaling $535.0 million were amended and restated to extend the maturity date by one year to December 31, 2025. The remaining $200.0 million promissory note and any accrued and unpaid interest are due on the earlier of (i) September 11, 2026 or (ii) upon the occurrence and during the continuance of an event of default (as defined in the note).

◦Pursuant to the terms of the amended and restated promissory note, the amended $505.0 million December 2023 promissory note is comprised of the Tranche 1 principal amount of $125.0 million and the Tranche 2 principal amount of $380.0 million. All Tranche 2 principal amount of $380.0 million and any accrued and unpaid interest can be converted into shares of the company’s stock at $8.2690 per share at the option of the noteholder. The interest rates for the Tranche 1 principal amount and Tranche 2 principal amount of the $505.0 million December 2023 promissory note were Term SOFR plus 8.0% per annum and Term SOFR plus 7.5% per annum, respectively.

◦The $200.0 million convertible promissory note bears interest at Term SOFR plus 8.0% per annum. The noteholder has the sole option to convert all of the outstanding principal amount and accrued but unpaid interest into shares of the company’s common stock at a conversion price of $1.9350 per share.

◦The $30.0 million convertible promissory note bears interest at Term SOFR plus 8.0% per annum. The noteholder has the sole option to convert all of the outstanding principal amount and accrued but unpaid interest into shares of the company’s common stock at a conversion price of $2.28 per share.

There can be no assurance that the company can refinance these promissory notes 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 refinanced indebtedness would increase. These risks could materially adversely affect the company’s financial condition, cash flows and results of operations.

•On December 29, 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 will be tiered payments initially ranging from 3.00% to 7.00% (or after funding of the Second Payment, 4.50% to 10.00%), subject to increase or decrease, following December 31, 2029 (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 True-Up Payment to Oberland in an amount equal to 100% of the Cumulative Purchaser Payments as of the Test Date, less the aggregate amount of our previous payments to Oberland as of the Test Date. See Note 9, 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 regarding the RIPA.

•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 N-803 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, 2023, 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. We may need to seek additional sources of capital to satisfy the CVR obligations if they are achieved.

•In connection with our acquisition of VivaBioCell, we are obligated to pay the former owners approximately $2.2 million of contingent consideration upon the achievement of a regulatory milestone relating to the GMP-in-a-Box technology.

Discussion of Consolidated Cash Flows

The following discussion of ImmunityBio’s cash flows is based on the consolidated statements of cash flows in Part II, Item 8. “Financial Statements and Supplementary Data” and is not meant to be an all‑inclusive discussion of the changes in its cash flows for the years presented below.

The following table sets forth our primary sources and uses of cash for the years indicated (in thousands):

Operating Activities

During the year ended December 31, 2023, net cash used in operating activities of $366.8 million consisted of a net loss of $583.9 million, partially offset by $213.1 million in adjustments for non-cash items and $3.9 million of cash provided by net working capital. Adjustments for non-cash items primarily consisted of $49.2 million in stock-based compensation expense, $47.6 million in change in fair value of warrant liabilities, $42.4 million in amortization of debt issuance costs and accretion of discounts, $36.2 million in change in fair value of convertible notes, $18.5 million in depreciation and amortization expense, $9.2 million in non-cash interest primarily related to related-party promissory notes, $6.1 million in non-cash lease expense related to operating lease right‑of‑use assets, $2.0 million of transaction costs allocable to warrant liabilities, $1.6 million in unrealized losses on equity securities driven by a decrease in the value of our investments, $0.9 million in loss on impairment of intangible assets, partially offset by $0.5 million in other items, and a decrease of $0.1 million in amortization of premiums, net of discounts on marketable debt securities. The changes in net working capital consisted primarily of an increase of $6.7 million in accrued expenses, a decrease of $5.9 million in prepaid expenses and other current assets, and a decrease of $1.9 million in other assets, partially offset by a decrease of $6.5 million in accounts payable, a decrease of $3.0 million in operating lease liabilities, and a decrease of $1.1 million in due to related parties.

The changes in net working capital consisted primarily of an increase of $16.6 million in prepaid and other current assets, and decreases of $4.3 million in operating lease liabilities and $1.2 million with related parties, partially offset by an increase of $8.0 million in accounts payable, an increase of $4.1 million in accrued expenses and other liabilities, and a decrease of $2.0 million in investment and other assets. Adjustments for non-cash items primarily consisted of $40.2 million in stock-based compensation expense, $18.3 million in depreciation and amortization expense, $16.3 million in amortization of debt issuance costs and accretion of discounts, $11.7 million in non-cash interest primarily related to related-party promissory notes, $5.9 million in non‑cash lease expense related to operating lease right-of-use assets, $4.2 million in unrealized losses on equity securities driven by a decrease in the value of our investments, $1.3 million in loss on impairment of fixed assets, $1.3 million in amortization of premiums, net of discounts, on marketable debt securities, $1.1 million in transaction costs allocable to a warrant liability, a non-cash $0.7 million loss on the impairment of intangible assets, and $0.3 million in other non-cash items, reduced by a $13.5 million change in fair value of a warrant liability.

We have historically experienced negative cash flows from operating activities, with such negative cash flows likely to continue for the foreseeable future.

Investing Activities

During the year ended December 31, 2023, net cash used in investing activities was $30.5 million, which included cash outflows of $30.6 million in purchases of property, plant and equipment (including construction in progress and the completion of a warehouse facility), and $10.4 million in purchases of marketable debt securities, partially offset by cash inflows of $10.5 million from maturities and sales of marketable debt and equity securities. Our investments in property, plant and equipment are primarily related to acquisitions of equipment that will be used for the manufacturing of our product candidates and expenditures related to the build out of our manufacturing facilities.

During the year ended December 31, 2022, net cash provided by investing activities was $27.3 million, which included cash inflows of $162.0 million from maturities and sales of marketable debt and equity securities, partially offset by $78.2 million of purchases of property, plant and equipment (including construction in progress and depreciable property acquired in the Dunkirk acquisition), $34.3 million of purchases of marketable debt securities, $21.2 million for purchase of intangible assets (related to the Dunkirk acquisition), and a $1.0 million investment in a joint venture. Our investments in property, plant and equipment are primarily related to acquisitions of equipment that will be used for the manufacturing of our product candidates and expenditures related to the build out of our manufacturing facilities.

We expect to accelerate our capital spending as we scale our cGMP manufacturing capabilities, which will require significant capital for the foreseeable future.

Financing Activities

During the year ended December 31, 2023, net cash provided by financing activities was $558.3 million, which consisted of $258.7 million in net proceeds from issuances of related-party promissory notes, $192.8 million in net proceeds from payments received pursuant to the RIPA, $84.4 million in net proceeds from registered direct offerings, $16.1 million in net proceeds from the ATM offering, $9.5 million in net proceeds from issuance of common stock in connection with the RIPA, and $0.3 million in proceeds from the exercise of stock options, partially offset by $3.4 million used for payment of payroll tax withholding in connection with the net share settlement of vested RSUs, and $0.1 million used for principal payments of finance leases.

During the year ended December 31, 2022, net cash provided by financing activities was $233.6 million, which consisted of $174.1 million in net proceeds from issuances of related-party promissory notes, $47.3 million in net proceeds from a registered direct offering, and $13.1 million in net proceeds from the ATM offering, partially offset by $0.6 million related to net share settlement of vested RSUs for payment of payroll tax withholding and a $0.3 million used in other financing activities.

We will need to raise additional capital to fund our future cash needs.

Future Funding Requirements

From inception through the date of this Annual Report we have generated minimal revenue, we have no clinical products approved for commercial sale, and we have not generated any revenue from therapeutic and vaccine product candidates that are under development. We do not expect to generate significant revenue unless and until we obtain regulatory approval of and commercialize any of our product candidates, and we do not know when, or if, this will occur. In addition, we expect our operating expenses to significantly increase in connection with our ongoing development activities, particularly as we continue the research, development and clinical trials of, and seek regulatory approval for, our product candidates. We have also incurred and expect that we will continue to incur in the future additional costs associated with operating as a public company as well as costs related to future fundraising efforts. In addition, subject to obtaining regulatory approval of our product candidates, we expect to incur significant commercialization expenses for product sales, marketing, manufacturing and distribution. We anticipate that we will need substantial additional funding in connection with our continuing operations.

We expect that our operating expenses will increase substantially if and as we:

•continue research and development, including preclinical and clinical development of our existing product candidates;

•potentially seek regulatory approval for our product candidates;

•seek to discover and develop additional product candidates;

•establish a commercialization infrastructure and scale up our manufacturing and distribution capabilities to commercialize any of our product candidates for which we may obtain regulatory approval;

•seek to comply with regulatory standards and laws;

•maintain, leverage and expand our intellectual property portfolio;

•hire clinical, manufacturing, scientific and other personnel to support our product candidates’ development and future commercialization efforts;

•add operational, financial and management information systems and personnel; and

•incur additional legal, accounting and other expenses in operating as a public company.

As a result of continuing anticipated operating cash outflows, we believe that substantial doubt exists regarding our ability to continue as a going concern without additional funding or financial support. However, we believe our existing cash, cash equivalents, and investments in marketable securities, together with capital to be raised through equity offerings (including but not limited to the offering, issuance and sale by us of our common stock that may be issued and sold under the ATM, of which we had $208.8 million available for future issuance as of December 31, 2023, and a February 2023 shelf registration statement, of which we had $565.6 million available for future offerings as of December 31, 2023), and our potential ability to borrow from affiliated entities, will be sufficient to fund our operations through at least the next 12 months following the issuance date of the consolidated financial statements based primarily upon our Executive Chairman and Global Chief Scientific and Medical Officer’s intent and ability to support our operations with additional funds, including loans from affiliated entities, as required, which we believe alleviates such doubt. We may also seek to sell additional equity, through one or more follow-on public offerings, or in separate financings, or obtain a credit facility, issue other debt in compliance with the terms of the RIPA, or engage in strategic partnership transactions. However, we may not be able to secure such external financing in a timely manner or on favorable terms, if at all. Without additional funds, we may choose to delay or reduce our operating or investment expenditures. Further, because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we may need additional funds to meet our needs sooner than planned.

We will need to obtain additional financing to fund our future operations, including completing the development and commercialization of our 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.

128

Table of Contents

Our future funding requirements will depend on many factors, including, but not limited to:

•progress, timing, number, scope and costs of researching and developing our product candidates and our ongoing, planned and potential clinical trials;

•time and cost of regulatory approvals;

•our ability to successfully commercialize any product candidates, if approved and the costs of such commercialization activities;

•revenue from product candidates that we may commercialize, if any, including the selling prices for such potential products and the availability of adequate third-party coverage and reimbursement for patients;

•interest and principal payments on our related-party promissory notes, and payment of Revenue Interests, the Second Payment and Test Date payments due under the RIPA;

•cost of building, staffing and validating our own manufacturing facilities in the U.S., including having a product candidate successfully manufactured consistent with FDA and EMA regulations;

•terms, timing and costs of our current and any potential future collaborations, business or product acquisitions, CVRs, milestones, royalties, licensing or other arrangements that we have established or may establish;

•time and cost necessary to respond to technological, regulatory, political and market developments; and

•costs of filing, prosecuting, maintaining, defending and enforcing any patent claims and other intellectual property rights.

Unless and until we can generate a sufficient amount of revenues, we may finance future cash needs through public or private equity offerings, license agreements, debt financings, collaborations, strategic alliances and marketing 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, including but not limited to the offering, issuance and sale by us of our common stock that may be issued and sold under the ATM.

To the extent that we raise additional capital through the sale of equity or equity-linked securities (including warrants), convertible debt or under the ATM, our shelf registration statement, 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 terms may include liquidation or other preferences that adversely affect your rights as a stockholder. The incurrence of additional indebtedness would result in increased fixed payment obligations and could involve certain restrictive covenants, 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. 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. 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.

Contractual Obligations

We have material cash requirements to pay related-party affiliates and third parties under various contractual obligations discussed below:

•We are obligated to make payments to several related-party affiliates under written agreements and other informal arrangements. We are also obligated to pay interest and to repay principal under our related-party promissory notes. For information regarding our financing obligations, see Note 10, Related-Party Debt, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•We are obligated to make payments to Oberland associated with our revenue interest liability, which do not have a fixed repayment schedule. Oberland’s right to receive payments under the RIPA shall terminate when Oberland has received maximum payments (including any True-Up Payment) equal to 195.0% of the then Cumulative Purchaser Payments unless the RIPA is terminated prior to such date.

Under the terms of the agreement, prior to the Test Date, every $100.0 million of worldwide net sales, excluding those in China, of less than or equal to $600.0 million in a calendar year would result in a tiered Revenue Interest Payment of approximately $7.0 million or 7.0% (or $10.0 million or 10.0% after funding of the Second Payment). Worldwide net sales, excluding those in China, for a calendar year exceeding $600.0 million would result in a tiered Revenue Interest Payment of approximately $3.0 million or 3.0% (or $4.5 million or 4.5% after funding of the Second Payment) for every $100.0 million of worldwide net sales, excluding those in China, above the threshold.

In the future, cumulative worldwide net sales, excluding those in China, levels up to the Test Date will determine whether or not we are required to make a True-Up Payment and implement modified payment rates. The amount of the obligation and timing of payment is likely to change. See Note 9, 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 regarding the RIPA.

•We are obligated to make payments under our operating leases, which primarily consist of facility leases. See Note 8, Lease Arrangements, and Note 11, Related-Party Agreements, of the “Notes to Consolidated Financial Statements” that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for information regarding our lease obligations.

•In connection with the acquisitions of Altor and VivaBioCell, we are obligated to pay contingent consideration upon the achievement of certain milestones. See Note 7, Commitments and Contingencies—Contingent Consideration Related to Business Combinations, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for information regarding our contingent consideration obligations.

•We have contractual obligations to make payments to related-party affiliates and third parties under unconditional purchase arrangements. See Note 7, Commitments and Contingencies—Unconditional Purchase Obligations, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for information on these unconditional purchase obligations.

•We have certain contractual commitments that are expected to be paid in fiscal year 2024, depending on the progress of build outs, completion of services, and the realization of milestones associated with third-party agreements. This amounts totals $60.8 million and is primarily related to capital expenditures, open purchase orders as of December 31, 2023 for the acquisition of goods and services in the ordinary course of business, and near-term upfront milestone payments to third parties.

•In addition, we have contractual commitments that are expected to be paid in fiscal year 2025 and beyond based on the achievement of various development, regulatory and commercial milestones for agreements with third parties. These payments may not be realized or may be modified and are contingent upon the occurrence of various future events, substantially all of which have a high degree of uncertainty of occurring. As of December 31, 2023, the maximum amount that may be payable related to these commitments is $769.3 million.

•In connection with our leasehold interest in the Dunkirk Facility, we committed to spend an aggregate of $1.52 billion on operational expenses during the initial 10-year term, and an additional $1.50 billion on operational expenses if we elect to renew the lease for the additional 10-year term. These amounts are not included in the discussion above. See Note 6, Collaboration and License Agreements and Acquisition, 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 on these obligations.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to the valuation of equity-based awards, deferred income taxes and related valuation allowances, revenue interest liability, preclinical and clinical trial accruals, impairment assessments, CVR measurement and assessments, the measurement of right-of-use assets and lease liabilities, useful lives of long-lived assets, loss contingencies, fair value calculation of warrants and convertible promissory notes, fair value measurements, asset acquisition, and the assessment of our ability to fund our operations for at least the next 12 months from the date of issuance of these consolidated financial statements. We base our estimates on historical experience and on various other market-specific and relevant assumptions that we believe to be reasonable under the circumstances. Estimates are assessed each period and updated to reflect current information, such as the economic considerations related to the impact that any ongoing pandemic could have on our significant accounting estimates. Actual results could differ from those estimates.

While our significant accounting policies are more fully described in the notes accompanying our consolidated financial statements that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report, we believe the following accounting policies to be the most critical in understanding the judgments and estimates we use in preparing our consolidated financial statements:

Revenue Recognition

We have 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 nonexclusive license agreements with a limited number of pharmaceutical and biotechnology companies grant them the right to use our cell lines and intellectual property for non-clinical use. These agreements generally include upfront fees and annual research license fees for such use, as well as commercial license fees for sales of the licensee products developed or manufactured using our intellectual property and cell lines. We have generated revenues from product sales of our proprietary GMP-in-a-Box bioreactors and related consumables, primarily to related parties. Additionally, we also generated revenues from grant programs.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation based on relative standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied.

Under our license agreements with customers, we typically promise to provide a license to use certain cell lines and related patents, the related know-how, and future research and development data that affect the license. We have concluded that these promises represent one performance obligation due to the highly interrelated nature of the promises. We provide the cell lines and know-how immediately upon entering into the contracts. Research and development data are provided throughout the term of the contract when and if available.

The license agreements may include non-refundable upfront payments, event-based milestone payments, sales-based royalty payments, or some combination of these. The event-based milestone payments represent variable consideration and we use the most likely amount method to estimate this variable consideration. Given the high degree of uncertainly around the achievement of these milestones, we do not recognize revenue from these milestone payments until the uncertainty associated

131

Table of Contents

with these payments is resolved. We currently estimate variable consideration related to milestone payments to be zero and, as such, no revenue has been recognized for milestone payments. We recognize revenue from sales-based royalty payments when or as sales occur. On a quarterly basis, we re-evaluate our estimate of milestone variable consideration to determine whether any amount should be included in the transaction price and recorded in revenue prospectively.

We also have sold our proprietary GMP-in-a-Box bioreactors and related consumables to affiliated companies. The arrangements typically include delivery of bioreactors, consumables, and providing installation service and perpetual software licenses for using the equipment. We recognize revenue when customers obtain control and can benefit from the promised goods or services, generally upon installation of the bioreactors, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. Upfront payments and fees are recorded as deferred revenue upon receipt and recognized as revenue when we satisfy our performance obligations under these arrangements.

Grant revenue is typically paid for reimbursable costs incurred over the duration of the associated research project or clinical trial and is recognized either when expenses reimbursable under the grants have been incurred and payments under the grants become contractually due or when cash is received, depending on the certainty of payment and other factors specific to each grant.

Revenue Interest Liability

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. In addition, Oberland may purchase additional Revenue Interests from us in exchange for the $100.0 million Second Payment upon satisfaction of certain conditions specified in the RIPA. Under the RIPA, Oberland has the right to receive quarterly payments from us based on, among other things, a certain percentage of our worldwide net sales, excluding those in China, during such quarter. The RIPA is considered a sale of future revenues and is accounted for 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 this liability may vary during the term of the agreement depending on a number of factors, including the level of actual and forecasted net sales. 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, interest expense, and the time period for repayment.

Derivative Liabilities

Embedded derivatives that are required to be bifurcated from the underlying debt instrument that do not meet the derivative scope exception and equity classification criteria are accounted for and valued as separate financial instruments. The terms of an embedded derivative related to a contingent exercisable prepayment feature of a convertible note have been evaluated and deemed to require bifurcation. This embedded derivative will be initially measured at fair value and will be remeasured to fair value at each reporting date until the derivative is settled.

In addition, the RIPA contains certain features that meet the definition of being an embedded derivative requiring bifurcation as a separate compound financial instrument apart from the RIPA. The derivative liability is initially measured at fair value upon issuance and is subject to remeasurement at each reporting period with changes in fair value recognized in other expense, net, on the consolidated statement of operations.

Preclinical and Clinical Trial Accruals

As part of the process of preparing the consolidated financial statements, we are required to estimate expenses resulting from obligations under contracts with vendors, clinical research organizations and consultants. The financial terms of these contracts vary and may result in payment flows that do not match the periods over which materials or services are provided under such contracts.

132

Table of Contents

We estimate clinical trial and research agreement-related expenses based on the services performed, pursuant to contracts with research institutions and clinical research organizations and other vendors that conduct clinical trials and research on our behalf. In accruing clinical and research-related fees, we estimate the time period over which services will be performed and activity expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, we will adjust the accrual accordingly. Payments made under these arrangements in advance of the receipt of the related services are recorded as prepaid expenses until the services are rendered.

Research and Development Costs

Major components of research and development costs include cash compensation and other personnel-related expenses, stock-based compensation, depreciation and amortization expense on research and development property and equipment and intangible assets, costs of preclinical studies, clinical trials costs, including CROs and related clinical manufacturing, including third-party CMOs, costs of drug development, costs of materials and supplies, facilities cost, overhead costs, regulatory and compliance costs, and fees paid to consultants and other entities that conduct certain research and development activities on our behalf. Costs incurred in research and development are expensed as incurred.

The company classifies its research and development expenses as either external or internal. The company’s external research and development expenses support its various preclinical and clinical programs. The company’s internal research and development expenses include payroll and benefits expenses, facilities and equipment expense, and other indirect research and development expenses incurred in support of its research and development activities. The company’s external and internal resources are not directly tied to any one research or drug discovery program and are typically deployed across multiple programs and are not allocated to specific product candidates or development programs.

Included in research and development costs are clinical trial and research expenses based on the services performed pursuant to contracts with research institutions and clinical research organizations and other vendors that conduct clinical trials and research on our behalf. We record accruals for estimated costs under these contracts. When evaluating the adequacy of the accrued liabilities, we analyze the progress of the preclinical studies or clinical trials, including the phase or completion of events, invoices received, contracted costs and purchase orders. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period based on the facts and circumstances known at that time. Although we do not expect the estimates to be materially different from the amounts actually incurred, if the estimates of the status and timing of services performed differ from the actual status and timing of services performed, we may report amounts that are too high or too low in any particular period. Actual results could differ from our estimates. We adjust the accruals in the period when actual costs become known.

Contingencies

We record accruals for loss contingencies to the extent that we conclude it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. We accrue for the best estimate of a loss within a range; however, if no estimate in the range is better than any other, then we accrue the minimum amount in the range. If we determine that a material loss is reasonably possible, we disclose the possible loss or range of loss, or that the amount of loss cannot be estimated at this time. We evaluate, on a quarterly basis, developments in legal proceedings and other matters that could cause a change in the potential amount of the liability recorded or the range of potential losses disclosed. Moreover, we record gain contingencies only when they are realizable and the amount is known. Additionally, we record our rights to insurance recoveries, limited to the extent of incurred or probable losses, as a receivable when such recoveries have been agreed to with our third-party insurers and when receipt is deemed probable. This includes instances when our third-party insurers have agreed to pay, on our behalf, certain legal defense costs and settlement amounts directly to applicable law firms and a settlement fund.

Warrants

The company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in FASB ASC Topic 480, Distinguishing Liabilities from Equity (ASC 480) and FASB ASC Topic 815, Derivatives and Hedging (ASC 815). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are

133

Table of Contents

indexed to the company’s own stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For warrants that meet all criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital, on the consolidated statement of stockholders’ deficit at the time of issuance. For warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and on each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss in other expense, net, on the consolidated statement of operations. The fair value of the warrants was estimated using the Black-Scholes option pricing model.

Fair Value Option Election

The company accounted for a convertible note issued on March 31, 2023 under the FVO election of ASC 825 until it was amended and restated on December 29, 2023. Prior to its extinguishment on December 29, 2023, the convertible note was a debt host financial instrument containing embedded features wherein the entire financial instrument was initially measured at its issuance-date estimated fair value and then subsequently remeasured at estimated fair value on a recurring basis at each reporting period date.

Changes in the estimated fair value of this convertible note were recorded in other expense, net, on the consolidated statement of operations, except that changes in estimated fair value caused by changes in the instrument-specific credit risk were recorded in other comprehensive (loss) income. In accordance with ASC 470-50, when the convertible note was extinguished on December 29, 2023, the cumulative amount previously recorded in other comprehensive (loss) income resulting from changes in the instrument-specific credit risk were reclassified and reported in current earnings on the consolidated statement of operations.

Debt Modification and Extinguishment

The company evaluates amendments to its debt instruments in accordance with ASC 470-50. This evaluation includes comparing (1) if applicable, the net present value of future cash flows of the amended debt to that of the original debt and (2) the change in fair value of an embedded conversion feature to that of the carrying amount of the debt immediately prior to amendment to determine, in each case, if a change greater than 10% occurred. In instances where the net present value of future cash flows or the fair value of an embedded conversion feature, if any, changed more than 10%, the company applies extinguishment accounting. In instances where the net present value of future cash flows and the fair value of an embedded conversion feature, if any, changed less than 10%, the company accounts for the amendment to the debt as a debt modification. Gains and losses on debt amendments that are considered extinguishments are recognized in current earnings or in additional paid-in capital if the transactions are with entities under common control. Debt amendments that are considered debt modifications are accounted for prospectively through yield adjustments, based on the revised terms. The increase in fair value of the embedded conversion feature from the debt modification was accounted for as an increase in debt discount with a corresponding increase in additional paid-in capital. Legal fees and other costs incurred with third parties that are directly related to debt modifications are expensed as incurred. Amounts paid by the company to the lenders, are reflected as additional debt discount and amortized as an adjustment of interest expense over remaining term of modified debt using the effective interest rate method.

Stock-Based Compensation

We account for stock-based compensation under the provisions of FASB ASC Topic 718, Compensation—Stock Compensation (ASC 718). We estimate fair value of each stock option award on the date of grant using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the use of subjective assumptions, including, but not limited to, expected stock price volatility over the term of the awards and the expected term of the stock options. We measure the fair value of an equity-classified award at the grant date and recognize the stock-based compensation expense over the period of vesting on the straight-line basis for our outstanding share awards that do not contain a performance condition. For awards subject to performance-based vesting conditions, we assess the probability of the individual milestones under the award being achieved and stock-based compensation expense is recognized over the service period using the graded vesting method once management believes the performance criteria is probable of being met. For awards with service or performance conditions, we recognize the effect of forfeitures in compensation cost in the period that the award was forfeited.

134

Table of Contents

Business Combinations

Business combinations are accounted for using the acquisition method of accounting in accordance with ASC 805-50. These standards require that the total cost of acquisition be allocated to the tangible and intangible assets acquired and liabilities assumed based on their respective fair values at the date of acquisition, with the excess purchase price recorded as goodwill. The allocation of the purchase price is dependent upon certain valuations and other studies. Acquisition costs are expensed as incurred.

Contingent consideration incurred in connection with a business combination are recorded at their fair values on the acquisition date and re-measured at their fair values each subsequent reporting period until the related contingencies are resolved. The resulting changes in fair values are recorded as research and development expense, on the consolidated statements of operations and comprehensive income (loss). Changes in fair values reflect changes to our assumptions regarding probabilities of successful achievement of related milestones, the timing in which the milestones are expected to be achieved, and the discount rate used to estimate the fair value of the obligation.

Actual results could differ materially from those discussed in or implied by such forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Annual Report, particularly in Part I, Item 1A. “Risk Factors.” Except as required by law, we do not undertake any responsibility to update any of these factors or to announce publicly any revisions to any of the forward-looking statements contained in this or any document, whether as a result of new information, future events, or otherwise.

Our Business

ImmunityBio, Inc. is a clinical-stage biotechnology company developing next-generation therapies and vaccines that complement, harness, and amplify the immune system to defeat cancers and infectious diseases. We strive to be a vertically-integrated immunotherapy company designing and manufacturing our products so they are more effective, accessible, more conveniently stored, and more easily administered to patients.

Our broad immunotherapy and cell therapy platforms are designed to attack cancer and infectious pathogens by activating both the innate immune system—NK cells, dendritic cells, and macrophages—and the adaptive immune system—B cells and T cells—in an orchestrated manner. The goal of this potentially best-in-class approach is to generate immunogenic cell death thereby eliminating rogue cells from the body whether they are cancerous or virally infected and to ultimately establish an “immunological memory” that confers long-term benefit for the patient.

Table of Contents

Our business is based on the foundation of multiple platforms that collectively act on the entire immune response with the goal of targeted, durable, coordinated, and safe immunity against disease. These platforms and their associated product candidates are designed to overcome the limitations of the current standards of care in oncology and infectious diseases, such as checkpoint inhibitors and antiretroviral therapies. Our portfolio includes:

Our platforms include 9 first-in-human therapeutic agents that are currently being studied in 26 clinical trials—17 of which are in Phase 2 or 3 development—across 12 indications in liquid and solid tumors, including bladder, pancreatic and lung cancers. These are among the most frequent and lethal cancer types for which there are high failure rates for existing standards of care or, in some cases, no available effective treatment. In infectious diseases, our pipeline currently targets such pathogens as SARS-CoV-2 and HIV. We believe SARS-CoV-2 currently lacks a vaccine that provides long-term protection against the virus, particularly its variants, while HIV affects tens of millions of people globally and currently has no known cure.

We believe that our innovative approach to orchestrate and combine therapies for optimal immune system response will become a therapeutic foundation across multiple clinical indications. Additionally, we believe that data from multiple clinical trials indicates N-803 has broad potential to enhance the activity of therapeutic mAbs, including checkpoint inhibitors (e.g., Keytruda®), across a wide range of tumor types. N-803 is currently being studied in 21 clinical trials (both ImmunityBio and investigator-sponsored) across 12 indications. Although such designations may not lead to a faster development process or regulatory review and may not increase the likelihood that a product candidate will receive approval, Anktiva, ImmunityBio’s novel antibody cytokine fusion protein, has received Breakthrough Therapy and Fast Track designations in combination with BCG from the FDA for the treatment of patients with BCG-unresponsive NMIBC CIS with or without Ta or T1 disease. In May 2022, we announced the submission of a BLA to the FDA for our product candidate, Anktiva in combination with BCG for the treatment of patients with BCG-unresponsive NMIBC with CIS with or without Ta or T1 disease. In July 2022, we announced that the FDA had accepted our BLA for review and set a target PDUFA action date of May 23, 2023. It is unclear when the FDA will approve our BLA, if at all.

We have established GMP manufacturing capacity at scale with cutting-edge cell manufacturing expertise and ready-to-scale facilities, as well as extensive and seasoned R&D, clinical trial, and regulatory operations, and development teams.

The Merger

On December 21, 2020, NantKwest and NantCell entered into the Merger Agreement, pursuant to which NantKwest and NantCell agreed to combine their businesses. The Merger Agreement provided that a wholly-owned subsidiary of the company would merge with and into NantCell, with NantCell surviving the Merger as a wholly-owned subsidiary of the company.

On March 9, 2021, we completed the Merger pursuant to the terms of the Merger Agreement. Under the terms of the Merger Agreement, at the effective time of the Merger (the Effective Time), each share of NantCell common stock, par value $0.001 per share, issued and outstanding immediately prior to the Effective Time, subject to certain exceptions as set forth in the Merger Agreement, was converted automatically into a right to receive 0.8190 (the Exchange Ratio) newly issued shares of common stock, par value $0.0001 per share, of the company (Company Common Stock), with cash paid in lieu of any fractional shares. At the Effective Time, each share of the company’s common stock issued and outstanding immediately prior to the Effective Time, remained an issued and outstanding share of the combined company. At the Effective Time, each outstanding option, RSU or warrant to purchase NantCell common stock was converted using the Exchange Ratio into an option, RSU or warrant, respectively, on the same terms and conditions immediately prior to the Effective Time, to purchase shares of Company Common Stock.

Immediately following the Effective Time, the former stockholders of NantCell held approximately 71.5% of the outstanding shares of Company Common Stock and the stockholders of NantKwest as of immediately prior to the Merger held approximately 28.5% of the outstanding shares of Company Common Stock. As a result of the Merger and immediately following the Effective Time, Dr. Patrick Soon-Shiong, our Executive Chairman and Global Chief Scientific and Medical Officer, and his affiliates beneficially owned, in the aggregate, approximately 81.8% of the outstanding shares of Company Common Stock. Following the consummation of the Merger, the symbol for shares of the company’s common stock was changed to “IBRX.”

We incurred costs totaling $23.3 million in connection with the Merger, consisting of financial advisory, legal and other professional fees, of which $13.0 million and $10.3 million were recorded for the years ended December 31, 2021 and 2020, respectively.

Accounting Treatment of the Merger

The Merger represents a business combination pursuant to Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 805-50, Mergers, which was accounted for as a transaction between entities under common control as Dr. Soon‑Shiong and his affiliates were the controlling stockholders of both the company and NantCell for all of the periods presented in this report. As a result, all of the assets and liabilities of NantCell were combined with ours at their historical carrying amounts on the closing date of the Merger. We recast our prior period financial statements for the years ended December 31, 2021 and 2020 to reflect the conveyance of NantCell’s common shares as if the Merger had occurred as of the earliest date of the consolidated financial statements presented in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. All material intercompany accounts and transactions have been eliminated in consolidation.

COVID-19 Pandemic

The COVID-19 pandemic continues to present a substantial public health and economic challenge around the world. Through the date of this Annual Report, we have not seen a material adverse impact to our business from the pandemic. However, given the unprecedented and continuously evolving nature of the pandemic, we cannot at this time predict the specific extent, duration, or full impact that this pandemic may have on our financial condition and results of operations, including ongoing and planned clinical trials. More specifically, the pandemic may result in prolonged impacts that we cannot predict at this time and we expect that such uncertainties will continue to exist for the foreseeable future. The impact of the pandemic on our financial performance will depend on future developments, including the duration and spread of the outbreak, impact of potential variants and the related governmental advisories and restrictions. These developments and the impact of the ongoing pandemic on the financial markets and the overall economy are highly uncertain. If the financial markets and/or the overall economy are impacted for an extended period, our results may be adversely affected. In addition, we anticipate that enrollment of patients in certain studies will likely take longer than previously forecasted and that our clinical trials may require additional time to complete which would in turn impact the timeline of BLA submissions of our product candidates and subsequent revenue generation.

122

Table of Contents

These factors have been accounted for in the company’s anticipated upcoming milestones. During any such delays in our clinical trials, we will continue to incur fixed costs such as selling, general and administrative expenses and operating expenses related to our laboratory, GMP manufacturing, and office facilities.

Many of our office-based employees have been working from home since mid-March 2020. Essential staffing levels for our research and development operations remain in place, including maintaining key personnel in our laboratory and GMP manufacturing facilities. It is likely that the pandemic and resulting mitigation efforts could have an impact in the future on our third-party suppliers who manufacture laboratory supplies required for our in-house manufacturing process, which in turn could have an impact on having sufficient clinical product supply available for our clinical trials. We have addressed this in part by ensuring that we have sufficient supplies on hand to weather interruptions in our supply chain.

We continue to monitor the impact of the COVID-19 pandemic on our business, including our clinical trials, manufacturing facilities and capabilities, and ability to access necessary resources. For a discussion of the risks presented by the COVID-19 pandemic to our results of operations and financial condition, see Part I, Item 1A. “Risk Factors.”

Operating Results

From inception through the date of this Annual Report, we have generated minimal revenue from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables, and grant programs. We have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development. We have incurred net losses in each year since our inception and, as of December 31, 2022, we had an accumulated deficit of $2.4 billion. Our net losses attributable to ImmunityBio common stockholders were $416.6 million, $346.8 million, and $221.9 million for the years ended December 31, 2022, 2021 and 2020, respectively. Substantially all of our net losses resulted principally from costs incurred in connection with our ongoing clinical trials and operations, our research and development programs, and from selling, general and administrative costs associated with our operations, including stock-based compensation expense.

As of December 31, 2022, we had 725 employees. Personnel of related companies who provide corporate, general and administrative, certain research and development, and other support services under our shared services agreement with NantWorks are not included in this number. For additional information, see Note 10, Related-Party Agreements, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. In anticipation of the commercialization of select drug candidates, we expect to continue to incur significant expenses and increasing operating losses for the foreseeable future, which may fluctuate significantly from quarter-to-quarter and year-to-year. See “—Future Funding Requirements” below for a discussion of our anticipated expenditures and sources of capital we expect to access to fund these expenditures.

Collaboration Agreements

We anticipate that strategic collaborations will continue to be an integral part of our operations, providing opportunities to leverage our partners’ expertise and capabilities to gain access to new technologies and further expand the potential of our technologies and product candidates across relevant platforms. We believe we are well positioned to become a leader in immunotherapy due to our broad and vertically-integrated platforms and through complementary strategic partnerships.

We believe that our innovative approach to orchestrate and combine therapies for optimal immune system response will become a therapeutic foundation across multiple clinical indications. Additionally, we believe that data from multiple clinical trials indicates N-803 has broad potential to enhance the activity of therapeutic mAbs, including checkpoint inhibitors (e.g., Keytruda), across a wide range of tumor types. N-803 is currently being studied in 21 clinical trials (both ImmunityBio and investigator-sponsored) across 12 indications. We may also enter into supply arrangements for various investigational agents to be used in our clinical trials. See Note 6, Collaboration and License Agreements and Acquisition, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for a more detailed discussion regarding our collaboration and license agreements.

Our Executive Chairman, Global Chief Scientific and Medical Officer and our principal stockholder, founded and has a controlling interest in NantWorks, which is a collection of companies in the healthcare and technology space. We have entered into arrangements with NantWorks, and certain affiliates of NantWorks. Affiliates of NantWorks are also affiliates of the company due to the common control by and/or common ownership interest of our Executive Chairman and Global Chief Scientific and Medical Officer.

Related-Party Debt

The following discussion of the company’s related-party promissory notes does not purport to be complete and is qualified in its entirety by reference to the full text of the notes, copies of which are filed in Part IV, Item 15. “Exhibits and Financial Statement Schedules” of this Annual Report.

$50.0 million Variable-Rate Promissory Note

On December 12, 2022, the company executed a $50.0 million promissory note with Nant Capital, an entity affiliated with Dr. Soon-Shiong, our Executive Chairman and Global Chief Scientific and Medical Officer. This note bears interest at Term Secured Overnight Financing Rate (Term SOFR) plus 8.0% per annum. The accrued interest on this note shall be payable quarterly on the last business day of March, June, September and December, commencing on December 30, 2022. The outstanding principal amount and any accrued and unpaid interest are due on December 31, 2023. The company may prepay the outstanding principal amount, together with any accrued interest at any time, in whole or in part, without premium or penalty. The company must prepay the outstanding principal amount, together with any accrued interest, if requested by the holder, following the successful closing of a strategic collaboration transaction with a large biopharmaceutical company.

The company received net proceeds of $49.7 million, net of a $0.3 million origination fee paid to the lender, which the company intends to use for pre-commercialization efforts and clinical development programs, other research and development activities, capital expenditures, and other general corporate purposes.

Conversion of Fixed-Rate Promissory Note due 2025

On December 12, 2022, the company received written notice from NantWorks, the holder of the existing convertible promissory note of NantCell, Inc., a wholly-owned subsidiary of the company (the Existing Note), of its election to convert the entire outstanding principal and accrued interest under the Existing Note into shares of the company’s common stock. As of such date, the entire outstanding principal amount and accrued and unpaid interest due under the Existing Note was approximately $56.6 million, which were converted into 9,986,920 shares of the company’s common stock at a price of $5.67 per share in accordance with the terms of the Existing Note.

$125.0 million Variable-Rate Promissory Note

On August 31, 2022, the company executed a $125.0 million promissory note with Nant Capital that bears interest at Term SOFR plus 8.0% per annum. The accrued interest is payable quarterly on the last business day of March, June, September and December, commencing on September 30, 2022.

$300.0 million Variable-Rate Promissory Note

As of December 31, 2022, the company has a $300.0 million variable-rate promissory note with Nant Capital. On August 31, 2022, the terms of this promissory note were amended and restated to extend the maturity date of the loan from December 17, 2022 to December 31, 2023, increase the spread on the loan from Term SOFR plus 5.4% per annum to Term SOFR plus 8.0% per annum, and reset the quarterly interest payment date from the 17th of the month to the last business day of March, June, September and December, commencing on September 30, 2022. No other material terms or conditions of this variable-rate promissory note were modified as part of this amendment and restatement. In the event of a default on the loan (as defined in the promissory note), including if the company does not repay the loan at maturity, the company has the right, at its sole option, to convert the outstanding principal amount and accrued and unpaid interest due under this note into shares of the company’s common stock at a price of $5.67 per share.

There can be no assurance that the company can refinance the variable-rate promissory notes described above 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 refinanced indebtedness would increase. These risks could materially adversely affect the company’s financial condition, cash flows and results of operations.

Fixed-Rate Convertible Promissory Notes

As of December 31, 2022, the company has outstanding fixed-rate promissory notes with entities affiliated with Dr. Soon-Shiong in an aggregate amount of $262.4 million (consisting of principal and accrued and unpaid interest). These notes bear interest at a per annum rate ranging from 3.0% to 6.0%, provide that the outstanding principal is due and payable on September 30, 2025, and accrued and unpaid interest is payable on either upon maturity or, with respect to one of the notes, on a quarterly basis. The company may prepay the outstanding amount of any advance under such notes, together with accrued and unpaid interest, at any time, in whole or in part, without premium or penalty, now subject to an advance notice period of at least five business days, during which the lender can convert the amount requested to be prepaid by the company into shares of company common stock, as part of the amendment and restatement described below.

On August 31, 2022, the terms of each fixed-rate promissory note were amended and restated to include a conversion feature that gives each lender the right at any time, including upon notice of prepayment, at its sole option, to convert the entire outstanding principal amount and accrued and unpaid interest due under each note at the time of conversion into shares of the company’s common stock at a price of $5.67 per share. No other material terms or conditions of these fixed-rate promissory notes were modified as part of these amendments.

Immuno-Oncology Clinic, Inc.

We entered into multiple agreements with the Clinic to conduct clinical trials related to certain of our product candidates. The Clinic is a related party as it is owned by an officer of the company and NantWorks manages the administrative operations of the Clinic.

In 2021, we completed a review of alternative structures that could support our more complex clinical trial requirements and made a decision to explore a potential transition of clinical trials at the Clinic to a new structure (including contracting with a new, non-affiliated professional corporation) to be determined and agreed upon by all parties. We continue productive negotiations with potential partners around alternative structures and expect to complete the process during the year ending December 31, 2023, but there can be no assurance that we will be successful. For the year ended December 31, 2022, we incurred $2.4 million in research and development expense, on the consolidated statement of operations related to clinical trial and transition services provided by the Clinic.

See Note 9, Related-Party Debt, and Note 10, Related-Party Agreements, of the “Notes to Consolidated Financial Statements” that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for a more detailed discussion regarding our related-party agreements.

Components of our Results of Operations

Revenue

From inception through the date of this Annual Report, we have generated minimal revenue from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables, and grant programs. We have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development. If we fail to complete the development of our product candidates in a timely manner or fail to obtain regulatory approval for them, we may never be able to generate substantial future revenue.

Operating Expenses

We generally classify our operating expenses into research and development, and selling, general and administrative expenses. Personnel costs, including salaries, benefits, bonuses, and stock-based compensation expense comprise a significant component of our research and development, and selling, general and administrative expense categories. We allocate expenses associated with our facilities and information technology costs between these two categories, primarily based on the nature of each cost.

Research and Development

Research and development expense consists of expenses incurred while performing research and development activities to discover and develop our technology and product candidates. This includes conducting preclinical studies and clinical trials, manufacturing development efforts and activities related to regulatory filings for product candidates. We recognize research and development expenses as they are incurred.

Our research and development expenses primarily consist of:

•clinical trial and regulatory-related costs;

•expenses incurred under agreements with investigative sites and consultants that conduct our clinical trials;

•expenses incurred under collaborative agreements;

126

Table of Contents

•manufacturing and testing costs and related supplies and materials;

•employee-related expenses, including salaries, benefits, travel and stock-based compensation; and

•facility expenses dedicated to research and development.

The company classifies its research and development expenses as either external or internal. The company’s external research and development expenses support its various preclinical and clinical programs. The company’s internal research and development expenses include payroll and benefits expenses, facilities and equipment expense, and other indirect research and development expenses incurred in support of its research and development activities. The company’s external and internal resources are not directly tied to any one research or drug discovery program and are typically deployed across multiple programs and are not allocated to specific product candidates or development programs.

We expect our research and development expense to continue to increase significantly for the foreseeable future as we advance our product candidates through clinical development, including the conduct of our ongoing and any future clinical trials.

The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. The successful development of product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs required to complete the remaining development of any product candidates. This is due to the numerous risks and uncertainties associated with the development of product candidates.

The costs of clinical trials may vary significantly over the life of a project owing to, but not limited to, the following:

•per patient trial costs;

•the number of sites included in the clinical trials;

•the countries in which the clinical trials are conducted;

•the length of time required to enroll eligible patients;

•the number of patients that participate in the clinical trials;

•the number of doses that patients receive;

•the cost of comparative agents used in clinical trials;

•the drop-out or discontinuation rates of patients;

•potential additional safety monitoring or other studies requested by regulatory agencies;

•the duration of patient follow-up; and

•the safety profile and efficacy of the product candidate.

We have only one product candidate, Anktiva in combination with BCG for the treatment of patients with BCG-unresponsive NMIBC with CIS with or without Ta or T1 disease, for which we submitted a BLA to the FDA in May 2022. In July 2022, we announced that the FDA had accepted our BLA for review and set a target PDUFA action date of May 23, 2023. However, there can be no assurance that our product candidate will be approved for commercial sale by the target PDUFA action date, if ever. We do not expect any of our other product candidates to be commercially available for the foreseeable future, if ever.

127

Table of Contents

Selling, General and Administrative

Selling, general and administrative expense consists primarily of salaries and personnel-related costs, including employee benefits and any stock-based compensation, for employees performing functions other than research and development. This includes personnel in executive, finance, human resources, information technology, legal, and administrative support functions. Other selling, general and administrative expenses include facility-related costs not otherwise allocated to research and development expense, professional fees for auditing, tax and legal services, advertising costs, expenses associated with strategic business transactions and business development efforts, obtaining and maintaining patents, consulting costs, royalties and licensing costs, and costs of our information systems.

We expect that our selling, general and administrative expense will increase for the foreseeable future as we expand operations, build out information systems and increase our headcount to support continued research activities and the development of our clinical programs. We have incurred and expect that we will continue to incur in the future, additional costs associated with operating as a public company, including costs to comply with stock exchange listing and SEC requirements, future funding efforts, corporate governance, internal controls, investor relations, disclosure and similar requirements applicable to public companies. Additionally, if and when we believe that a regulatory approval of a product candidate appears likely, we expect to incur significant increases in our selling, general and administrative expense relating to the sales and marketing of the approved product candidate.

Other Income and Expense

Other income and expense consists primarily of interest income, interest expense, unrealized gains and losses on investments in equity securities and equity-method investments, realized gains and losses on both debt and equity securities, and gains and losses on foreign currency transactions.

Income Taxes

We are subject to U.S. federal income tax, as well as income tax in Italy, South Korea, California and other states. From inception through December 31, 2022, we have not been required to pay U.S. federal and state income taxes because of current losses from operations.

Discussion of Consolidated Results of Operations

Comparison of the Years Ended December 31, 2022 and 2021

Revenue

Revenue decreased $0.7 million for the year ended December 31, 2022, as compared to the year ended December 31, 2021. The decrease was primarily driven by less bioreactor and royalty revenue received in 2022.

Research and Development Expense

Research and development expenses were $248.1 million for the year ended December 31, 2022, compared to $196.0 million for the year ended December 31, 2021. The following table summarizes our research and development expenses for the years ended December 31, 2022 and 2021, together with the changes in those items (in thousands):

129

Table of Contents

Research and development expense increased $52.2 million primarily attributable to the following:

•A $23.0 million increase in external research and development expenses that was primarily due to a rise in CMO fees and drug materials purchased used in manufacturing, an increase in regulatory and compliance costs resulting from the BLA submission for our product candidate Anktiva, and higher equipment validation and qualification costs;

•A $13.8 million increase in personnel-related costs that was primarily the result of higher headcount additions for personnel involved in our quality control, clinical operations and drug discovery and development activities;

•An $18.3 million increase in equipment, depreciation, and facility costs that was primarily due to the expansion of our manufacturing facilities in California and New York, which resulted in increases in lease expense, maintenance costs, and depreciation expense; and

•A $2.9 million decrease in other research and development costs that was primarily attributable to greater nonclinical collaboration expenses in the current period allocated to our joint venture, partially offset by an increase in application costs associated with submitting the BLA for our product candidate Anktiva, an increase in impairment costs associated with a group of long-lived assets, and an increase in license fees.

We expect our research and development expenses to increase significantly for the foreseeable future as we continue to invest in research and development activities related to developing our product candidates and conduct our ongoing and planned clinical trials.

Selling, General and Administrative Expense

Selling, general and administrative expense decreased $32.5 million for the year ended December 31, 2022, as compared to the year ended December 31, 2021. The reduction in selling, general and administrative expense was primarily driven by a $29.5 million net decline in legal expenses as a result of greater insurance reimbursements received in the current period that offset current-period legal expenses, as well as $11.0 million in lower general consulting costs and insurance costs primarily due to Merger-related expenses incurred in the prior period. These decreases were partially offset by an increase of $4.7 million in personnel costs, including shared services costs and stock compensation costs as a result of a rise in headcount, recruiting costs and travel-related expenses, as well as an increase of $1.8 million in software license fees and an increase of $1.5 million in facility costs and other general administrative expenses.

Impairment of Intangible Assets

Impairment of intangible assets increased $0.7 million for the year ended December 31, 2022, compared to the year ended December 31, 2021, due to the write off of the organized workforce with definite lives as a result of the workforce reduction at the Dunkirk Facility.

Other Expense, Net

Other expense, net increased $46.4 million during the year ended December 31, 2022, as compared to the year ended December 31, 2021. The increase was due to a $48.7 million increase in interest expense driven by an increase in related‑party borrowings along with an increase in SOFR rates and amortization of debt discounts related to a gain on debt extinguishments, as well as an $11.3 million loss on our equity method investment in a joint venture, and an additional $0.9 million increase in other costs as a result of issuance costs allocated to the warrant liability. These increases were partially offset by a $13.5 million decrease in the fair value of our warrant liability and a $1.0 million decrease in net interest and investment losses as a result of higher interest income and lower unrealized losses related to marketable equity securities partially offset by amortization of premiums on our marketable debt securities.

Comparison of the Years Ended December 31, 2021 to 2020

See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations” of our Annual Report on Form 10-K filed with the SEC on March 1, 2022 for a discussion of the company’s results of operations for the year ended December 31, 2021 compared to the year ended December 31, 2020.

Financial Condition, Liquidity and Capital Resources

Sources of Liquidity

Our principal sources of liquidity are our existing cash, cash equivalents, and marketable securities. We have historically invested our cash primarily in investment grade short- to intermediate-term corporate debt securities, commercial paper, government-sponsored securities, U.S. treasury securities, and foreign government bonds and classify these investments as available-for-sale. Certain of these investments are subject to general credit, liquidity and other market risks. The general condition of the financial markets and the economy may increase those risks and may affect the value and liquidity of investments and restrict our ability to access the capital markets.

Cash and Marketable Securities on Hand

As of December 31, 2022, we had cash and cash equivalents, and marketable securities of $108.0 million compared to $317.9 million as of December 31, 2021. On April 30, 2021, we entered into an open market sale agreement (the Sale Agreement) with respect to an ATM offering program under which we may offer and sell, from time to time at our sole discretion, shares of our common stock, having an aggregate offering price of up to $500.0 million through our sales agent, which was subsequently reduced by $92.0 million during December 2022 in connection with a sale of our common stock. As of December 31, 2022, we had $225.4 million available for future stock issuances under the ATM. See Note 12, Stockholders’ Deficit, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

Proceeds from the ATM

For the year ended December 31, 2022, we received net proceeds totaling $13.1 million from the issuance of 2,051,894 shares under the ATM. We currently intend to use the net proceeds from this offering for pre-commercialization efforts and clinical development programs, other research and development activities, capital expenditures, and other general corporate purposes.

Proceeds from Registered Direct Offerings

On December 12, 2022, we entered into a securities purchase agreement with an institutional investor for the sale of 9,090,909 shares of our common stock, as well as warrants to purchase an additional 9,090,909 shares of common stock at an exercise price of $6.60 per share, for a purchase price of $5.50 per share and accompanying warrant, generating net proceeds of approximately $47.0 million, after deducting placement agent fees and other offering costs. We currently intend to use the net proceeds from this offering, together with other available funds, to progress our pre-commercialization efforts and clinical development programs, fund other research and development activities, for capital expenditures, and for other general corporate purposes.

On February 15, 2023, we entered into a securities purchase agreement with certain institutional investors for the sale of 14,072,615 shares of our common stock, as well as warrants to purchase an additional 14,072,615 shares of common stock at an exercise price of $4.2636 per share, for a purchase price of $3.5530 per share and accompanying warrant, generating net proceeds of approximately $47.0 million, after deducting placement agent fees and other estimated offering costs. The closing of the offering occurred on February 17, 2023. We currently intend to use the net proceeds from this offering, together with other available funds, to progress our pre-commercialization efforts and clinical development programs, fund other research and development activities, for capital expenditures, and for other general corporate purposes. We may also use a portion of the net proceeds to license intellectual property or to make acquisitions or investments. See “Subsequent Event” for further information.

In order to complete the development of our current product candidates, and implement our business plan, we will require substantial additional funding. Furthermore, changing circumstances may cause us to increase our spending significantly faster than we currently anticipate, and we may need to raise even greater amounts of funds sooner if we choose to expand more rapidly than we presently anticipate. Moreover, our fixed expenses such as rent and other contractual commitments are substantial and are expected to increase in the future.

Uses of Liquidity

In addition to the cash used to fund our operating activities discussed in “—Future Funding Requirements” below, we will require cash to settle the following obligations:

•As of December 31, 2022, our indebtedness payable at maturity totals $737.4 million (excluding unamortized related-party notes discounts), held by entities affiliated with Dr. Soon-Shiong.

Of this amount, $475.0 million is due and payable on December 31, 2023. In the event of a default on the $300.0 million loan (as defined in the promissory note), including if we do not repay the loan at maturity, the company has the right, at its sole option, to convert the outstanding principal amount and accrued and unpaid interest due under this note into shares of the company’s common stock at price of $5.67 per share. There can be no assurance that the company can refinance these promissory notes 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 refinanced indebtedness would increase. These risks could materially adversely affect the company’s financial condition, cash flows and results of operations.

The remaining $262.4 million is due and payable on September 30, 2025, including any accrued and unpaid interest. The company can prepay the outstanding principal (together with accrued and unpaid interest), in whole or in part, at any time without premium or penalty and without the prior consent of the lender. On August 31, 2022, the terms of each fixed-rate promissory note were amended and restated to include a conversion feature that gives each lender the right at any time, including upon notice of prepayment, at its sole option, to convert the entire outstanding principal amount and accrued and unpaid interest due under each note at the time of conversion into shares of the company’s common stock at a price of $5.67 per share.

•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 the successful regulatory approval of a BLA by the FDA, or foreign equivalent, for N-803 by December 31, 2022, and approximately $304.0 million of contingent consideration upon calendar-year worldwide net sales of N-803 exceeding $1.0 billion prior to December 31, 2026, with amounts payable in cash or shares of our common stock or a combination thereof.

With respect to the regulatory milestone CVR agreement, in May 2022 we announced the submission of a BLA to the FDA for our product candidate, Anktiva (N-803) in combination with BCG for the treatment of patients with BCG-unresponsive NMIBC with CIS with or without Ta or T1 disease. In July 2022 we announced that the FDA had accepted our BLA for review and set a target PDUFA action date of May 23, 2023. It is unclear when the FDA will approve our BLA, if at all. The FDA did not approve our BLA on or before December 31, 2022, and therefore the regulatory milestone was not met, and the regulatory milestone CVR agreement terminated in accordance with its terms.

With respect to the net sales milestone CVR agreement, as of December 31, 2022, 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. We may need to seek additional sources of capital to satisfy the CVR obligations if they are achieved.

•In connection with our acquisition of VivaBioCell, we are obligated to pay the former owners approximately $2.1 million of contingent consideration upon the achievement of a regulatory milestone relating to the GMP-in-a-Box technology.

Discussion of Consolidated Cash Flows

The following discussion of ImmunityBio’s cash flows is based on the consolidated statements of cash flows in Part II, Item 8. “Financial Statements and Supplementary Data” and is not meant to be an all‑inclusive discussion of the changes in its cash flows for the periods presented below.

The following table sets forth our primary sources and uses of cash for the years indicated (in thousands):

Operating Activities

For the year ended December 31, 2022, net cash used in operating activities of $337.5 million consisted of a net loss of $417.3 million and $8.0 million of cash used in net working capital, partially offset by $87.8 million in adjustments for non-cash items. The changes in net working capital consisted primarily of an increase of $16.6 million in prepaid expenses and other current assets, and decreases of $4.3 million in operating lease liabilities and $1.2 million with related parties, partially offset by an increase of $8.0 million in accounts payable, an increase of $4.1 million in accrued expenses and other liabilities, and a decrease of $2.0 million in investment and other assets. Adjustments for non-cash items primarily consisted of $40.2 million in stock-based compensation expense, $18.3 million in depreciation and amortization expense, $16.3 million in amortization of debt issuance costs and accretion of discounts, $11.7 million in non-cash interest primarily related to related-party promissory notes, $5.9 million in non-cash lease expense related to operating lease right‑of‑use assets, $4.2 million in unrealized loss on equity securities driven by a decrease in the value of our investments, $1.3 million in loss on impairment of fixed assets, $1.3 million in amortization of premiums, net of discounts, on marketable debt securities, $1.1 million in transaction costs allocable to warrant liability, a non-cash $0.7 million loss on the impairment of intangible assets, and $0.3 million in other non-cash items, reduced by a $13.5 million change in fair value of warrant liability.

For the year ended December 31, 2021, net cash used in operating activities of $274.4 million consisted of a net loss of $349.8 million and $19.1 million of cash used in net working capital, partially offset by $94.5 million in adjustments for non-cash items. The change in net working capital consisted primarily of decreases of $10.2 million with related parties and $4.2 million in operating lease liabilities, an increase of $4.0 million in investment and other assets, a decrease of $3.7 million in accounts payable, and an increase of $2.2 million in prepaid and other current assets, partially offset by an increase of $5.2 million in accrued expenses and other liabilities. Adjustments for non-cash items primarily consisted of $57.2 million in stock-based compensation expense, $14.2 million in depreciation and amortization, $12.4 million in non-cash interest primarily related to related-party loans, $4.9 million in non‑cash lease expense related to operating lease right-of-use assets, $4.6 million in unrealized losses on equity securities driven primarily by a decrease in the value of our investments, $0.8 million in other non-cash items, and $0.4 million in amortization of premiums, net of discounts, on marketable debt securities.

We have historically experienced negative cash flows from operating activities, with such negative cash flows likely to continue for the foreseeable future.

Investing Activities

For the year ended December 31, 2022, net cash provided by investing activities was $27.3 million, which included cash inflows of $162.0 million from maturities and sales of marketable debt and equity securities, partially offset by $78.2 million of purchases of property, plant and equipment (including construction in process and depreciable property acquired in the Dunkirk acquisition), $34.3 million of purchases of marketable debt securities, $21.2 million for purchase of intangible assets (related to the Dunkirk acquisition), and a $1.0 million investment in a joint venture. Our investments in property, plant and equipment are primarily related to acquisitions of equipment that will be used for the manufacturing of our product candidates and expenditures related to the build out of our manufacturing facilities.

For the year ended December 31, 2021, net cash used in investing activities was $84.9 million, which included $141.8 million in purchases of marketable debt securities and $33.6 million of purchases of property, plant and equipment, partially offset by cash inflows of $70.0 million from maturities and sales of marketable debt and equity securities and $20.5 million in proceeds from the sale of 557 Doug St, LLC that were allocated to the book value of the property. Our investments in property, plant and equipment are primarily related to acquisitions of equipment that will be used for the manufacturing of our product candidates and expenditures related to the build out of our manufacturing facilities.

We expect to accelerate our capital spending as we scale our GMP manufacturing capabilities, which will require significant capital for the foreseeable future.

Financing Activities

For the year ended December 31, 2022, net cash provided by financing activities was $233.6 million, which consisted of $174.1 million in net proceeds from issuances of related-party promissory notes, $47.3 million in net proceeds from a registered direct offering, and $13.1 million in net proceeds from the ATM offering, partially offset by $0.6 million related to net share settlement of vested RSUs for payment of payroll tax withholding and $0.3 million used in other financing activities.

For the year ended December 31, 2021, net cash provided by financing activities was $505.4 million, which consisted of $338.5 million in net proceeds from issuances of related-party promissory notes, $164.5 million in net proceeds from the ATM offering, $5.5 million in proceeds from exercises of stock options and a $1.4 million capital contribution representing excess proceeds received over book value from the sale of 557 Doug St, LLC to an entity under common control. Net cash used in financing activities consisted of $4.1 million related to net share settlement of vested RSUs for payment of payroll tax withholding and a $0.4 million payment for contingent consideration.

Comparison of the Years Ended December 31, 2021 to 2020

See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations” of our Annual Report on Form 10-K filed with the SEC on March 1, 2022 for a discussion of the company’s consolidated cash flows for the year ended December 31, 2021 compared to the year ended December 31, 2020.

Future Funding Requirements

From inception through the date of this Annual Report we have generated minimal revenue, we have no clinical products approved for commercial sale and we have not generated any revenue from therapeutic and vaccine product candidates that are under development. We do not expect to generate significant revenue unless and until we obtain regulatory approval of and commercialize any of our product candidates, and we do not know when, or if, this will occur. In addition, we expect our operating expenses to significantly increase in connection with our ongoing development activities, particularly as we continue the research, development and clinical trials of, and seek regulatory approval for, our product candidates. We have also incurred and expect that we will continue to incur in the future additional costs associated with operating as a public company as well as costs related to future fundraising efforts. In addition, subject to obtaining regulatory approval of our product candidates, we expect to incur significant commercialization expenses for product sales, marketing, manufacturing and distribution. We anticipate that we will need substantial additional funding in connection with our continuing operations.

We expect that our operating expenses will increase substantially if and as we:

•continue research and development, including preclinical and clinical development of our existing product candidates;

•potentially seek regulatory approval for our product candidates;

•seek to discover and develop additional product candidates;

•establish a commercialization infrastructure and scale up our manufacturing and distribution capabilities to commercialize any of our product candidates for which we may obtain regulatory approval;

•seek to comply with regulatory standards and laws;

•maintain, leverage and expand our intellectual property portfolio;

•hire clinical, manufacturing, scientific and other personnel to support our product candidates’ development and future commercialization efforts;

•add operational, financial and management information systems and personnel; and

•incur additional legal, accounting and other expenses in operating as a public company.

As a result of continuing anticipated operating cash outflows, we believe that substantial doubt exists regarding our ability to continue as a going concern without additional funding or financial support. However, we believe our existing cash, cash equivalents, and investments in marketable securities, together with capital to be raised through equity offerings (including the ATM) and our potential ability to borrow from affiliated entities, will be sufficient to fund our operations through at least the next 12 months following the issuance date of the consolidated financial statements based primarily upon our Executive Chairman and Global Chief Scientific and Medical Officer’s intent and ability to support our operations with additional funds, including loans from affiliated entities, as required, which we believe alleviates such doubt. We may also seek to sell additional equity, through one or more follow-on public offerings, or in separate financings, or obtain a credit facility. However, we may not be able to secure such external financing in a timely manner or on favorable terms. Without additional funds, we may choose to delay or reduce our operating or investment expenditures. Further, because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we may need additional funds to meet our needs sooner than planned.

We will need to obtain additional financing to fund our future operations, including completing the development and commercialization of our 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.

135

Table of Contents

Our future funding requirements will depend on many factors, including, but not limited to:

•progress, timing, number, scope and costs of researching and developing our product candidates and our ongoing, planned and potential clinical trials;

•time and cost of regulatory approvals;

•our ability to successfully commercialize any product candidates, if approved and the costs of such commercialization activities;

•revenue from product candidates that we may commercialize, if any, including the selling prices for such potential products and the availability of adequate third-party coverage and reimbursement for patients;

•cost of building, staffing and validating our own manufacturing facilities in the U.S., including having a product candidate successfully manufactured consistent with FDA and European Medicines Agency regulations;

•terms, timing and costs of our current and any potential future collaborations, business or product acquisitions, CVRs, milestones, royalties, licensing or other arrangements that we have established or may establish;

•time and cost necessary to respond to technological, regulatory, political and market developments; and

•costs of filing, prosecuting, maintaining, defending and enforcing any patent claims and other intellectual property rights.

Unless and until we can generate a sufficient amount of revenues, we may finance future cash needs through public or private equity offerings, license agreements, debt financings, collaborations, strategic alliances and marketing 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, including but not limited to the offering, issuance and sale by us of up to a maximum aggregate amount of $500.0 million of our common stock that may be issued and sold under the ATM, which was subsequently reduced by $92.0 million during December 2022 in connection with a sale of our common stock. As of December 31, 2022, we had $225.4 million available for future stock issuances under the ATM. See Note 12, Stockholders’ Deficit, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

To the extent that we raise additional capital through the sale of equity or equity-linked securities, including convertible debt or through the ATM or other offerings, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a stockholder. The incurrence of additional indebtedness would result in increased fixed payment obligations and could involve certain restrictive covenants, 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. 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. 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.

Contractual Obligations

We have material cash requirements to pay related-party affiliates and third parties under various contractual obligations discussed below:

•We are obligated to make payments to several related-party affiliates under written agreements and other informal arrangements. We are also obligated to pay interest and to repay principal under our related-party notes payable. For information regarding our financing obligations, see Note 9, Related-Party Debt, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•We are obligated to make payments under our operating leases, which primarily consist of facility leases. For information regarding our lease obligations, see Note 8, Lease Arrangements, and Note 10, Related-Party Agreements, of the “Notes to Consolidated Financial Statements” that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•In connection with the acquisitions of Altor and VivaBioCell, we are obligated to pay contingent consideration upon the achievement of certain milestones. For information regarding our contingent consideration obligations, see Note 7, Commitments and Contingencies—Contingent Consideration Related to Business Combinations, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•We have contractual obligations to make payments to related-party affiliates and third parties under unconditional purchase arrangements. For information on these unconditional purchase obligations, see Note 7, Commitments and Contingencies—Unconditional Purchase Obligations, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•We have certain contractual commitments that are expected to be paid within one year, depending on the progress of build outs, completion of services, and the realization of milestones associated with third-party agreements. This amount totals $121.1 million and is primarily related to capital expenditures, open purchase orders as of December 31, 2022 for the acquisition of goods and services in the ordinary course of business, and near term upfront milestone payments to third parties.

•In addition, we have contractual commitments that are expected to be paid in fiscal year 2024 and beyond based on the achievement of various development, regulatory and commercial milestones for agreements with third parties. These payments may not be realized or may be modified and are contingent upon the occurrence of various future events, substantially all of which have a high degree of uncertainty of occurring. As of December 31, 2022, the maximum amount that may be payable related to these commitments is $780.3 million.

•In connection with our leasehold interest in the Dunkirk Facility, we committed to spend an aggregate of $1.52 billion on operational expenses during the initial 10-year term, and an additional $1.50 billion on operational expenses if we elect to renew the lease for the additional 10-year term. These amounts are not included in the discussion above. See Note 6, Collaboration and License Agreements and Acquisition, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to the valuation of equity-based awards, deferred income taxes and related valuation allowances, preclinical and clinical trial accruals, impairment assessments, contingent value right measurement and assessments, the measurement of right-of-use assets and lease liabilities, useful lives of long-lived assets, loss contingencies, fair value calculation of warrants, fair value measurements, asset acquisition, and the assessment of our ability to fund our operations for at least the next 12 months from the date of issuance of these consolidated financial statements. We base our estimates on historical experience and on various other market-specific and relevant assumptions that we believe to be reasonable under the circumstances. Estimates are assessed each period and updated to reflect current information, such as the economic considerations related to the impact that the ongoing coronavirus pandemic could have on our significant accounting estimates. Actual results could differ from those estimates.

While our significant accounting policies are more fully described in the notes accompanying our consolidated financial statements that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report, we believe the following accounting policies to be the most critical in understanding the judgments and estimates we use in preparing our consolidated financial statements:

Revenue Recognition

We have 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 nonexclusive license agreements with a limited number of pharmaceutical and biotechnology companies grant them the right to use our cell lines and intellectual property for non-clinical use. These agreements generally include upfront fees and annual research license fees for such use, as well as commercial license fees for sales of the licensee products developed or manufactured using our intellectual property and cell lines. We have generated revenues from product sales of our proprietary GMP-in-a-Box bioreactors and related consumables to related parties. Additionally, we also generated revenues from grant programs.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation based on relative standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied.

Under our license agreements with customers, we typically promise to provide a license to use certain cell lines and related patents, the related know-how, and future research and development data that affect the license. We have concluded that these promises represent one performance obligation due to the highly interrelated nature of the promises. We provide the cell lines and know-how immediately upon entering into the contracts. Research and development data are provided throughout the term of the contract when and if available.

The license agreements may include non-refundable upfront payments, event-based milestone payments, sales-based royalty payments, or some combination of these. The event-based milestone payments represent variable consideration and we use the most likely amount method to estimate this variable consideration. Given the high degree of uncertainly around the achievement of these milestones, we do not recognize revenue from these milestone payments until the uncertainty associated with these payments is resolved. We currently estimate variable consideration related to milestone payments to be zero and, as such, no revenue has been recognized for milestone payments. We recognize revenue from sales-based royalty payments when or as the sales occur. On a quarterly basis, we re-evaluate our estimate of milestone variable consideration to determine whether any amount should be included in the transaction price and recorded in revenue prospectively.

138

Table of Contents

We also have sold our proprietary GMP-in-a-Box bioreactors and related consumables to affiliated companies. The arrangements typically include delivery of bioreactors, consumables, and providing installation service and perpetual software licenses for using the equipment. We recognize revenue when customers obtain control and can benefit from the promised goods or services, generally upon installation of the bioreactors, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. Upfront payments and fees are recorded as deferred revenue upon receipt and recognized as revenue when we satisfy our performance obligations under these arrangements.

Grant revenue is typically paid for reimbursable costs incurred over the duration of the associated research project or clinical trial and is recognized when expenses reimbursable under the grants have been incurred and payments under the grants become contractually due.

Warrants

The company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC Topic 480, Distinguishing Liabilities from Equity (ASC 480), and ASC Topic 815, Derivatives and Hedging (ASC 815). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the company’s own stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For warrants that meet all criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and on each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss in other income (expense), net, on the consolidated statement of operations. The fair value of the warrants was estimated using the Black-Scholes option pricing model.

Business Combinations

Business combinations are accounted for using the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations (ASC 805). These standards require that the total cost of acquisition be allocated to the tangible and intangible assets acquired and liabilities assumed based on their respective fair values at the date of acquisition, with the excess purchase price recorded as goodwill. The allocation of the purchase price is dependent upon certain valuations and other studies. Acquisition costs are expensed as incurred.

Contingent consideration incurred in connection with a business combination are recorded at their fair values on the acquisition date and re-measured at their fair values each subsequent reporting period until the related contingencies are resolved. The resulting changes in fair values are recorded as research and development expense, on the consolidated statements of operations and comprehensive income (loss). Changes in fair values reflect changes to our assumptions regarding probabilities of successful achievement of related milestones, the timing in which the milestones are expected to be achieved, and the discount rate used to estimate the fair value of the obligation.

Preclinical and Clinical Trial Accruals

As part of the process of preparing the consolidated financial statements, we are required to estimate expenses resulting from obligations under contracts with vendors, clinical research organizations and consultants. The financial terms of these contracts vary and may result in payment flows that do not match the periods over which materials or services are provided under such contracts.

We estimate clinical trial and research agreement-related expenses based on the services performed, pursuant to contracts with research institutions and clinical research organizations and other vendors that conduct clinical trials and research on our behalf. In accruing clinical and research-related fees, we estimate the time period over which services will be performed and activity expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, we will adjust the accrual accordingly. Payments made under these arrangements in advance of the receipt of the related services are recorded as prepaid expenses until the services are rendered.

Research and Development Costs

Major components of research and development costs include cash compensation and other personnel-related expenses, stock-based compensation, depreciation and amortization expense on research and development property and equipment and intangible assets, costs of preclinical studies, clinical trials costs, including CROs, and related clinical manufacturing, including CMOs, costs of drug development, costs of materials and supplies, facilities cost, overhead costs, regulatory and compliance costs, and fees paid to consultants and other entities that conduct certain research and development activities on our behalf. Costs incurred in research and development are expensed as incurred.

Included in research and development costs are clinical trial and research expenses based on the services performed pursuant to contracts with research institutions and clinical research organizations and other vendors that conduct clinical trials and research on our behalf. We record accruals for estimated costs under these contracts. When evaluating the adequacy of the accrued liabilities, we analyze the progress of the preclinical studies or clinical trials, including the phase or completion of events, invoices received, contracted costs and purchase orders. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period based on the facts and circumstances known at that time. Although we do not expect the estimates to be materially different from the amounts actually incurred, if the estimates of the status and timing of services performed differ from the actual status and timing of services performed, we may report amounts that are too high or too low in any particular period. Actual results could differ from our estimates. We adjust the accruals in the period when actual costs become known.

Stock-Based Compensation

We account for stock-based compensation under the provisions of ASC Topic 718, Compensation—Stock Compensation (ASC 718). We estimate fair value of each stock option award on the date of grant using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the use of highly subjective assumptions, including, but not limited to, expected stock price volatility over the term of the awards and the expected term of the stock options. We measure the fair value of an equity-classified award at the grant date and recognize the stock-based compensation expense over the period of vesting on the straight-line basis for our outstanding share awards that do not contain a performance condition. For awards subject to performance-based vesting conditions, we assess the probability of the individual milestones under the award being achieved and stock-based compensation expense is recognized over the service period using the graded vesting method once management believes the performance criteria is probable of being met. If factors change and we employ different assumptions, share-based compensation expense may differ significantly from what we have recorded in the past. For awards with service or performance conditions, we recognize the effect of forfeitures in compensation cost in the period that the award was forfeited.

Table of Contents

Contingencies

We record accruals for loss contingencies to the extent that we conclude it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. We accrue for the best estimate of a loss within a range; however, if no estimate in the range is better than any other, then we accrue the minimum amount in the range. If we determine that a material loss is reasonably possible, we disclose the possible loss or range of loss, or that the amount of loss cannot be estimated at this time.

Because of the inherent uncertainty and unpredictability related to these matters, accruals are based on what we believe to be the best information available at the time of our assessment, including the legal facts and circumstances of the case, status of the proceedings, applicable law and the views of legal counsel. Upon the final resolution of such matters, it is possible that there may be a loss in excess of the amount recorded, and such amounts could have a material adverse effect on our results of operations, cash flows or financial position. We evaluate, on a quarterly basis, developments in legal proceedings and other matters that could cause a change in the potential amount of the liability recorded or the range of potential losses disclosed. Moreover, we record gain contingencies only when they are realizable and the amount is known. Additionally, we record our rights to insurance recoveries, limited to the extent of incurred or probable losses, as a receivable when such recoveries have been agreed to with our third-party insurers and when receipt is deemed probable. This includes instances when our third-party insurers have agreed to pay, on our behalf, certain legal defense costs and settlement amounts directly to applicable law firms and a settlement fund.

Subsequent Event

Registered Direct Offering

On February 15, 2023, we entered into a securities purchase agreement with certain institutional investors for the sale of 14,072,615 shares of our common stock, as well as warrants to purchase an additional 14,072,615 shares of common stock at an exercise price of $4.2636 per share, for a purchase price of $3.5530 per share and accompanying warrant, generating net proceeds of approximately $47.0 million, after deducting placement agent fees and other estimated offering costs. The warrants are immediately exercisable after the issuance date and expire two years after the initial issuance date. The closing of the offering occurred on February 17, 2023. We currently intend to use the net proceeds from this offering, together with other available funds, to progress our pre-commercialization efforts and clinical development programs, fund other research and development activities, for capital expenditures, and for other general corporate purposes. We may also use a portion of the net proceeds to license intellectual property or to make acquisitions or investments.

ITEM 7.     MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion and analysis of our financial condition and results of operations should be read together with the description of our business appearing in Part I, Item 1. “Business” and the consolidated financial statements and related notes thereto in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. This discussion contains forward-looking statements as a result of many factors, including those set forth under Part I, Item 1. “Business—Forward-Looking Statements” and Item 1A. “Risk Factors,” and elsewhere in this Annual Report. These statements are based on the current expectations and assumptions of management that are subject to risks and uncertainties. Actual results could differ materially from those discussed in or implied by such forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Annual Report, particularly in Part I, Item 1A. “Risk Factors.” Except as required by law, we do not undertake any responsibility to update any of these factors or to announce publicly any revisions to any of the forward-looking statements contained in this or any document, whether as a result of new information, future events, or otherwise.

Our Business

ImmunityBio, Inc. is a clinical-stage biotechnology company developing next-generation therapies and vaccines that complement, harness, and amplify the immune system to defeat cancers and infectious diseases. We strive to be a vertically-integrated immunotherapy company designing and manufacturing our products so they are more effective, accessible, more conveniently stored, and more easily administered to patients.

Our broad immunotherapy and cell therapy platforms are designed to attack cancer and infectious pathogens by activating both the innate immune system—NK cells, dendritic cells, and macrophages—and the adaptive immune system—B cells and T cells—in an orchestrated manner. The goal of this potentially best-in-class approach is to generate immunogenic cell death thereby eliminating rogue cells from the body whether they are cancerous or virally infected and to ultimately establish an “immunological memory” that confers long-term benefit for the patient.

Our business is based on the foundation of multiple platforms that collectively act on the entire immune response with the goal of targeted, durable, coordinated, and safe immunity against disease. These platforms and their associated product candidates are designed to overcome the limitations of the current standards of care in oncology and infectious disease, such as checkpoint inhibitors and antiretroviral therapies. We have established one of the most comprehensive portfolios of immunotherapy and vaccine platforms, which include:

Table of Contents

We believe that our innovative approach to orchestrate and combine therapies for optimal immune system response will become a therapeutic foundation across multiple clinical indications. Although such designations may not lead to a faster development process or regulatory review and may not increase the likelihood that a product candidate will receive approval, Anktiva, our novel antibody cytokine fusion protein, has received Breakthrough Therapy and Fast Track designations in combination with BCG from the FDA for BCG-unresponsive NMIBC CIS. Based on the reported results of the trial, we have initiated discussions with the FDA to file a BLA for Anktiva (to be branded VesAnktiva for intravesical administration) plus BCG for BCG-unresponsive NMIBC CIS. Additionally, we believe that data from multiple clinical trials indicates Anktiva has broad potential to enhance the activity of therapeutic mAbs, including checkpoint inhibitors (e.g., Keytruda®), across a wide range of tumor types.

Our platforms, which include 17 first-in-human therapeutic agents, are being studied in 26 actively recruiting clinical trials—17 of which are in Phase 2 or 3 development—across 13 indications in liquid and solid tumors, including bladder, pancreatic and lung cancers. These are among the most frequent and lethal cancer types for which there are high failure rates for existing standards of care or, in some cases, no available effective treatment. In infectious disease, our pipeline currently targets such pathogens as SARS-CoV-2 and HIV. We believe SARS-CoV-2 currently lacks a vaccine that provides long-term protection against the virus, particularly its variants, while HIV affects tens of millions of people globally and currently has no known cure.

We have established GMP manufacturing capacity at scale with cutting-edge cell manufacturing expertise and ready-to-scale facilities, as well as extensive and seasoned R&D, clinical trial, and regulatory operations, and development teams.

The Merger

On December 21, 2020, we and NantCell, Inc. (formerly known as ImmunityBio, Inc., a private company) (NantCell) entered into an Agreement and Plan of Merger (the Merger Agreement), pursuant to which we and NantCell agreed to combine our businesses. The Merger Agreement provided that a wholly-owned subsidiary of the company would merge with and into NantCell (the Merger), with NantCell surviving the Merger as a wholly-owned subsidiary of the company.

113

Table of Contents

On March 9, 2021, we completed the Merger pursuant to the terms of the Merger Agreement. Under the terms of the Merger Agreement, at the effective time of the Merger (the Effective Time), each share of NantCell common stock, par value $0.001 per share, issued and outstanding immediately prior to the Effective Time, subject to certain exceptions as set forth in the Merger Agreement, was converted automatically into a right to receive 0.8190 (the Exchange Ratio) newly issued shares of common stock, par value $0.0001 per share, of the company (Company Common Stock), with cash paid in lieu of any fractional shares. At the Effective Time, each share of the company’s common stock issued and outstanding immediately prior to the Effective Time, remained an issued and outstanding share of the combined company. At the Effective Time, each outstanding option, warrant or restricted stock unit to purchase NantCell common stock was converted using the Exchange Ratio into an option, warrant or restricted stock unit, respectively, on the same terms and conditions immediately prior to the Effective Time, to purchase shares of Company Common Stock.

Immediately following the Effective Time, the former stockholders of NantCell held approximately 71.5% of the outstanding shares of Company Common Stock and the stockholders of the company as of immediately prior to the Merger held approximately 28.5% of the outstanding shares of Company Common Stock. As a result of the Merger and immediately following the Effective Time, Dr. Patrick Soon-Shiong, our Executive Chairman and Global Chief Scientific and Medical Officer, and his affiliates beneficially owned, in the aggregate, approximately 81.8% of the outstanding shares of Company Common Stock. Following the consummation of the Merger, the symbol for shares of the company’s common stock was changed to “IBRX.”

We incurred costs totaling $23.3 million in connection with the Merger, consisting of financial advisory, legal and other professional fees, of which $13.0 million and $10.3 million were recorded for the years ended December 31, 2021 and 2020, respectively.

Accounting Treatment of the Merger

The Merger represents a business combination pursuant to Financial Accounting Standards Board Accounting Standards Codification Topic 805-50, Mergers, which is accounted for as a transaction between entities under common control as Dr. Soon‑Shiong and his affiliates were the controlling stockholders of both the company and NantCell for all of the periods presented in this report. As a result, all of the assets and liabilities of NantCell were combined with ours at their historical carrying amounts on the closing date of the Merger. We have recast our prior period financial statements to reflect the conveyance of NantCell’s common shares as if the Merger had occurred as of the earliest date of the consolidated financial statements presented in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. All material intercompany accounts and transactions have been eliminated in consolidation.

COVID-19 Pandemic

The COVID-19 pandemic continues to present a substantial public health and economic challenge around the world. Through the date of this Annual Report, we have not seen a material adverse impact to our business from the pandemic. However, given the unprecedented and continuously evolving nature of the pandemic, we cannot at this time predict the specific extent, duration, or full impact that this pandemic may have on our financial condition and results of operations, including ongoing and planned clinical trials. More specifically, the pandemic may result in prolonged impacts that we cannot predict at this time and we expect that such uncertainties will continue to exist for the foreseeable future. The impact of the pandemic on our financial performance will depend on future developments, including the duration and spread of the outbreak, impact of potential variants and the related governmental advisories and restrictions. These developments and the impact of the ongoing pandemic on the financial markets and the overall economy are highly uncertain. If the financial markets and/or the overall economy are impacted for an extended period, our results may be adversely affected. In addition, we anticipate that enrollment of patients in certain studies will likely take longer than previously forecasted and that our clinical trials may require additional time to complete which would in turn impact the timeline of BLA submissions of our product candidates and subsequent revenue generation.

These factors have been accounted for in the company’s anticipated upcoming milestones. During any such delays in our clinical trials, we will continue to incur fixed costs such as selling, general and administrative expenses and operating expenses related to our laboratory, GMP manufacturing, and office facilities.

114

Table of Contents

Many of our office-based employees have been working from home since mid-March 2020. Essential staffing levels for our research and development operations remain in place, including maintaining key personnel in our laboratory and GMP manufacturing facilities. It is likely that the pandemic and resulting mitigation efforts could have an impact in the future on our third-party suppliers who manufacture laboratory supplies required for our in-house manufacturing process, which in turn could have an impact on having sufficient clinical product supply available for our clinical trials. We have addressed this in part by ensuring that we have sufficient supplies on hand to weather interruptions in our supply chain.

We continue to monitor the impact of the COVID-19 pandemic on our business, including our clinical trials, manufacturing facilities and capabilities, and ability to access necessary resources. For a discussion of the risks presented by the COVID-19 pandemic to our results of operations and financial condition, see Part I, Item 1A. “Risk Factors.”

Operating Results

From inception through the date of this Annual Report, we have generated minimal revenue from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables, and grant programs. We have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development. We have incurred net losses in each year since our inception and, as of December 31, 2021, we had an accumulated deficit of $2.0 billion. Our net losses attributable to ImmunityBio common stockholders were $346.8 million, $221.9 million, and $157.8 million for the years ended December 31, 2021, 2020 and 2019, respectively. Substantially all of our net losses resulted principally from costs incurred in connection with our ongoing clinical trials and operations, our research and development programs, and from selling, general and administrative costs associated with our operations, including stock-based compensation expense.

As of December 31, 2021, we had 587 employees. Personnel of related companies who provide corporate, general and administrative, manufacturing strategy, research and development, regulatory and clinical trial strategy and other support services under our shared services agreement with NantWorks are not included in this number. For additional information, see Note 8, Related-Party Agreements, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report. In anticipation of the commercialization of select drug candidates, we expect to continue to incur significant expenses and increasing operating losses for the foreseeable future, which may fluctuate significantly from quarter-to-quarter and year-to-year. See “—Future Funding Requirements” below for a discussion of our anticipated expenditures and sources of capital we expect to access to fund these expenditures.

Collaboration Agreements

As we continue the development of our pipeline, we anticipate that strategic collaborations with established biopharma companies and other research-based entities will become integral to our operations and the development of novel combination therapies. These collaborations will provide ImmunityBio with a range of opportunities to leverage our partners’ expertise and capabilities to further expand the potential of our technologies and product candidates. We are currently pursuing this aspect of our business in 13 clinical trials studying our IL-15 superagonist fusion protein Anktiva in combination with complementary, approved therapies to determine if Anktiva may have broad potential to enhance the activity of those therapies, including mAbs and other standard-of-care therapeutics across a wide range of tumor types. We believe we are well positioned to become a leader in immunotherapy through the combined strength of our broad and vertically-integrated platform and complementary strategic partnerships. We may also enter into supply arrangements for various investigational agents to be used in our clinical trials. See Note 6, Collaboration and License Agreements, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report for a more detailed discussion regarding our collaboration and license agreements.

Agreements with Related Parties

Our Executive Chairman, Global Chief Scientific and Medical Officer and our principal stockholder, founded and has a controlling interest in NantWorks, which is a collection of companies in the healthcare and technology space. We have entered into arrangements with NantWorks, and certain affiliates of NantWorks, to facilitate the development of new immunotherapies for our product pipeline. Affiliates of NantWorks are also affiliates of the company due to the common control by and/or common ownership interest of our Executive Chairman and Global Chief Scientific and Medical Officer.

Related-Party Promissory Notes

As of December 31, 2021, we have outstanding fixed-rate promissory notes with entities affiliated with Dr. Soon-Shiong in an aggregate amount of $306.3 million, including accrued interest. These notes bear interest at a per annum rate ranging from 3.0% to 6.0%, provide that the outstanding principal is due and payable on September 30, 2025, and accrued and unpaid interest is payable on either upon maturity or, with respect to one of the notes, on a quarterly basis beginning June 30, 2021. We may prepay the outstanding amount of any advance under such notes, together with accrued and unpaid interest, at any time, in whole or in part, without premium or penalty.

In addition, as of December 31, 2021 we have a $300.0 million variable-rate promissory note with an entity affiliated with Dr. Soon-Shiong that is due and payable on December 17, 2022. This loan bears interest at Term SOFR + 5.4%, which is compounded annually and payable quarterly commencing on March 17, 2022. As of December 31, 2021, the interest rate on this loan was 5.47%. In the event of a default on the loan (as defined in the promissory note), including if we do not repay the loan at maturity, the company has the right, at its sole option, to convert the outstanding principal amount and accrued and unpaid interest due under this note into shares of the company’s common stock at price of $5.67 per share. There can be no assurance that we can refinance this promissory note 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 refinanced indebtedness would increase. These risks could materially adversely affect our financial condition, cash flows and results of operations.

Immuno-Oncology Clinic, Inc.

We entered into multiple agreements with Immuno-Oncology Clinic, Inc. (the Clinic) to conduct clinical trials related to certain of our product candidates. The Clinic is a related party as it is owned by an officer of the company and NantWorks manages the administrative operations of the Clinic.

In the second quarter of 2021, based on a review of our then updated clinical trial programs post-Merger, we updated our estimates of the investigator fees for the clinical trials that were underway or planned at the Clinic. As certain programs costs are excluded from and certain services are subject to credit adjustments under the Clinic agreements, we determined the expected future fees for services to be performed were less than the carrying value of the prepaid asset on the consolidated balance sheets. As a result, we partially wrote down the value of our prepayments under the Clinic agreements and recorded approximately $1.9 million in research and development expense, on the consolidated statement of operations for the three months ended June 30,2021. In November 2021, we completed a review of alternative structures that could support our more complex clinical trial requirements and made a decision to explore a potential transition of clinical trials at the Clinic to a new structure (including contracting with a new, non-affiliated professional corporation) to be determined and agreed upon by all parties and currently planned for the first half of 2022. Based on this decision to explore a potential transition, we determined that it was more likely than not that the previously recorded prepaid asset would not result in the collection of fees for services performed by the Clinic as contemplated in the original agreements. As a result, we wrote down the remaining value of our prepaid asset and recorded approximately $2.5 million in research and development expense, on the consolidated statement of operations for the three months ended December 31, 2021.

Components of our Results of Operations

Revenue

From inception through the date of this Annual Report, we have generated minimal revenue from non-exclusive license agreements related to our cell lines, the sale of our bioreactors and related consumables, and grant programs. We have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development. If we fail to complete the development of our product candidates in a timely manner or fail to obtain regulatory approval for them, we may never be able to generate substantial future revenue.

Operating Expenses

We generally classify our operating expenses into research and development, and selling, general and administrative expenses. Personnel costs, including salaries, benefits, bonuses, and stock-based compensation expense comprise a significant component of our research and development, and selling, general and administrative expense categories. We allocate expenses associated with our facilities and information technology costs between these two categories, primarily based on the nature of each cost.

Research and Development

Research and development expense consists of expenses incurred while performing research and development activities to discover and develop our technology and product candidates. This includes conducting preclinical studies and clinical trials, manufacturing development efforts and activities related to regulatory filings for product candidates. We recognize research and development expenses as they are incurred. Our research and development expenses primarily consist of:

•clinical trial and regulatory-related costs;

•expenses incurred under agreements with investigative sites and consultants that conduct our clinical trials;

•expenses incurred under collaborative agreements;

•manufacturing and testing costs and related supplies and materials;

•employee-related expenses, including salaries, benefits, travel and stock-based compensation; and

•facility expenses dedicated to research and development.

We typically use our employee, consultant and infrastructure resources across our development programs. We track outsourced development costs by product candidate or development program, but we do not allocate personnel costs, other internal costs or external consultant costs to specific product candidates or development programs.

We expect our research and development expense to continue to increase significantly for the foreseeable future as we advance our product candidates through clinical development, including the conduct of our ongoing and any future clinical trials.

The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. The successful development of product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs required to complete the remaining development of any product candidates. This is due to the numerous risks and uncertainties associated with the development of product candidates.

118

Table of Contents

The costs of clinical trials may vary significantly over the life of a project owing to, but not limited to, the following:

•per patient trial costs;

•the number of sites included in the clinical trials;

•the countries in which the clinical trials are conducted;

•the length of time required to enroll eligible patients;

•the number of patients that participate in the clinical trials;

•the number of doses that patients receive;

•the cost of comparative agents used in clinical trials;

•the drop-out or discontinuation rates of patients;

•potential additional safety monitoring or other studies requested by regulatory agencies;

•the duration of patient follow-up; and

•the efficacy and safety profile of the product candidate.

We have only one product candidate, Anktiva, currently planned for a BLA submission to the FDA in the near future. However, there can be no assurance that it will be approved for commercial sale in the near term, if ever. We do not expect any of our other product candidates to be commercially available for the foreseeable future, if ever.

Selling, General and Administrative

Selling, general and administrative expense consists primarily of salaries and personnel-related costs, including employee benefits and any stock-based compensation, for employees performing functions other than research and development. This includes personnel in executive, finance, human resources, information technology, legal, and administrative support functions. Other selling, general and administrative expenses include facility-related costs not otherwise allocated to research and development expense, professional fees for auditing, tax and legal services, advertising costs, expenses associated with strategic business transactions and business development efforts, obtaining and maintaining patents, consulting costs, royalties and licensing costs, and costs of our information systems.

We expect that our selling, general and administrative expense will increase for the foreseeable future as we expand operations, build out information systems and increase our headcount to support continued research activities and the development of our clinical programs. We have incurred and expect that we will continue to incur in the future, additional costs associated with operating as a public company, including costs to comply with stock exchange listing and SEC requirements, future funding efforts, corporate governance, internal controls, investor relations, disclosure and similar requirements applicable to public companies. Additionally, if and when we believe that a regulatory approval of a product candidate appears likely, we expect to incur significant increases in our selling, general and administrative expense relating to the sales and marketing of the approved product candidate.

Other Income and Expense

Other income and expense consists primarily of interest income, interest expense, unrealized gains and losses on investments in equity securities and equity-method investments, realized gains and losses on both debt and equity securities, and gains and losses on foreign currency transactions.

Income Taxes

We are subject to U.S. federal income tax, as well as income tax in Italy, South Korea, California and other states. From inception through December 31, 2021, we have not been required to pay U.S. federal and state income taxes because of current and accumulated net operating losses.

Discussion of Results of Operations

Comparison of the Years Ended December 31, 2021 and 2020

Revenue

Revenue increased $0.3 million for the year ended December 31, 2021, as compared to the year ended December 31, 2020. The increase was primarily driven by royalty revenue in 2021 from a sublicense agreement.

Research and Development Expense

Research and development expense increased $56.5 million for the year ended December 31, 2021, as compared to the year ended December 31, 2020. The increase in research and development expense was primarily driven by a $32.1 million increase in compensation expense, including an $18.6 million increase in stock-based compensation expense due to new grants issued to employees and executives and a $13.5 million increase in personnel costs due to higher headcount in support of our continued research and development efforts, a $6.9 million increase in clinical trial expenses and regulatory costs related to our Anktiva and COVID-19 programs, including a $4.4 million expense associated with the write down of a prepaid asset with the Clinic, a $6.6 million increase in facilities expense, primarily related to the expansion of one of our manufacturing facilities in El Segundo, California during 2021 and increased maintenance costs at our various facilities, a $5.5 million increase in quality control and research and development-related technology expense, a $3.5 million increase in laboratory supply expense related to our COVID-19 programs ramp up and NK-92 and M-ceNK cell therapy research, and a $2.4 million increase in shared services costs to support our growth. These increases were partially offset by a $0.5 million decrease in consulting costs.

We expect our research and development expense to increase significantly for the foreseeable future as we advance our product candidates through clinical development and conduct our ongoing and planned clinical trials.

Table of Contents

Selling, General and Administrative Expense

Selling, general and administrative expense increased $63.9 million for the year ended December 31, 2021, as compared to the year ended December 31, 2020. The increase in selling, general and administrative expense was primarily attributable to a $42.2 million increase in compensation expense, including a $36.4 million increase in stock-based compensation expense driven by awards granted to employees and executives and option modifications resulting in incremental stock-based compensation expense in 2021 and a $5.8 million increase in personnel costs related to higher headcount needed to support our business activities, a $19.3 million increase in professional services fees related to Merger costs, SOX compliance, the combined company audit, our recruitment and business growth strategy, various legal matters, and new system implementations, and a $3.2 million increase in insurance costs, primarily due to higher directors’ and officers’ insurance renewal rates and increased insurance coverage. These increases were partially offset by an $0.8 million decrease in shared service costs and other general and administrative expense.

Impairment of Intangible Assets

During the year ended December 31, 2020, the company recorded an impairment charge totaling $10.7 million to write down the carrying value of indefinite-lived in-process research and development intangible assets associated with the acquisition of Receptome, LLC to zero in connection with the decision to discontinue certain programs based on results gathered from preclinical data.

Other Expense, Net

Other expense, net increased $14.4 million for the year ended December 31, 2021, as compared to the year ended December 31, 2020. The increase was due to a $6.5 million decrease in interest and investment income, driven primarily by a $6.2 million net unrealized loss from equity securities and a $0.9 million decrease in interest income, partially offset by a $0.4 million decrease in accretion of investment premiums and $0.2 million of net realized gains on investments; a $5.8 million increase in interest expense driven primarily by higher related-party borrowings; an $0.8 million loss on equity method investment; and a $1.3 million decrease in other income in our subsidiaries and foreign exchanges losses.

Comparison of the Years Ended December 31, 2020 to 2019

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations” in the Management’s Discussion and Analysis of Financial Condition and Results of Operations of ImmunityBio, Inc. filed as Exhibit 99.3 to our Current Report on Form 8-K/A filed with the SEC on April 22, 2021 for a discussion of the company’s results of operations for the year ended December 31, 2020 compared to the year ended December 31, 2019.

Financial Condition, Liquidity and Capital Resources

Sources of Liquidity

Our principal sources of liquidity are our existing cash, cash equivalents, and marketable securities. We have historically invested our cash primarily in investment grade short- to intermediate-term corporate debt securities, commercial paper, government-sponsored securities, U.S. treasury securities, and foreign government bonds and classify these investments as available-for-sale. Certain of these investments are subject to general credit, liquidity and other market risks. The general condition of the financial markets and the economy may increase those risks and may affect the value and liquidity of investments and restrict our ability to access the capital markets.

121

Table of Contents

As of December 31, 2021, we had cash and cash equivalents, and marketable securities of $317.9 million compared to $97.0 million as of December 31, 2020. On April 30, 2021, we entered into an Open Market Sale Agreement (the Sale Agreement) with respect to an at-the-market (the ATM) offering program under which we may offer and sell, from time to time at our sole discretion, shares of our common stock, having an aggregate offering price of up to $500.0 million through our sales agent. For the year ended December 31, 2021, we received net proceeds totaling $164.5 million from the issuance of 13,295,817 shares under the ATM, which we expect to use for general corporate purposes, including to progress our clinical development programs, fund other research and development activities, make capital expenditures and fund working capital. We may also use a portion of the net proceeds to license intellectual property or to make acquisitions or investments. Although we made a decision to pause our ATM offering in the fourth quarter of 2021 after our $300.0 million promissory note financing with Nant Capital and do not have an active issuance notice with our sales agent, we expect to re-initiate activity at any time based on market dynamics and/or capital requirements. As of December 31, 2021, we had $330.8 million available for future stock issuances under the ATM.

In order to complete the development of our current product candidates, and implement our business plan, we will require substantial additional funding. Furthermore, changing circumstances may cause us to increase our spending significantly faster than we currently anticipate, and we may need to raise even greater amounts of funds sooner if we choose to expand more rapidly than we presently anticipate. Moreover, our fixed expenses such as rent and other contractual commitments are substantial and are expected to increase in the future.

Uses of Liquidity

In addition to the cash used to fund our operating activities discussed in “—Future Funding Requirements” below, we will require cash to settle the following obligations:

•As of December 31, 2021, our indebtedness totals $605.6 million (consisting of related-party promissory notes and accrued and unpaid interest, less unamortized debt issuance costs), held by entities affiliated with Dr. Soon-Shiong. Of this amount, $300.0 million is due and payable on December 17, 2022. In the event of a default on the loan (as defined in the promissory note), including if we do not repay the loan at maturity, the company has the right, at its sole option, to convert the outstanding principal amount and accrued and unpaid interest due under this note into shares of the company’s common stock at price of $5.67 per share. There can be no assurance that we can refinance this promissory note 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 refinanced indebtedness would increase. These risks could materially adversely affect our financial condition, cash flows and results of operations.

The remaining $306.3 million is due and payable on September 30, 2025, including any accrued and unpaid interest. We may prepay the outstanding amount of any advance under such notes, together with accrued and unpaid interest, at any time, in whole or in part, without premium or penalty.

•In connection with our acquisition of Altor, we issued CVRs under which we have agreed to pay the prior stockholders of Altor approximately $304.0 million upon successful approval of the BLA, or foreign equivalent, for Anktiva by December 31, 2022 and approximately $304.0 million upon the first calendar year prior to December 31, 2026 in which worldwide net sales of Anktiva exceed $1.0 billion (with payments payable in cash or shares of our common stock or a combination thereof). Dr. Soon-Shiong and his related party hold approximately $279.5 million in the aggregate of CVRs, and they have both irrevocably agreed to receive shares of common stock in satisfaction of their CVRs. We may be required to pay the other prior Altor stockholders up to $164.2 million in settlement of the CVRs relating to the regulatory milestone and up to $164.2 million of the CVRs relating to the sales milestone should they choose to have the CVRs paid in cash instead of common stock. We may need to seek additional sources of capital to satisfy the CVR obligations if they are achieved.

•In connection with our acquisition of VivaBioCell, we are obligated to pay the former owners approximately $2.3 million of contingent consideration upon the achievement of a regulatory milestone relating to the GMP-in-a-Box technology.

Discussion of Consolidated Cash Flows

The following discussion of ImmunityBio’s cash flows is based on the consolidated statements of cash flows in Part II, Item 8. “Financial Statements and Supplementary Data” and is not meant to be an all‑inclusive discussion of the changes in its cash flows for the periods presented below.

The following table sets forth our primary sources and uses of cash for periods indicated:

Operating Activities

For the year ended December 31, 2021, net cash used in operating activities of $274.4 million consisted of a net loss of $349.8 million and $19.1 million of cash used in net working capital changes, partially offset by $94.5 million in adjustments for non-cash items. The changes in net working capital consisted primarily of decreases of $10.2 million with related parties, $4.2 million in operating lease liabilities, $4.0 million in investment and other assets, $3.7 million in accounts payable, and $2.2 million in prepaid and other current assets, partially offset by an increase of $5.2 million in accrued expenses and other liabilities. Adjustments for non-cash items primarily consisted of $57.2 million in stock-based compensation expense, $14.2 million in depreciation and amortization expense, $12.5 million in non-cash interest related primarily to related-party promissory notes, $4.9 million in non-cash lease expense related to operating lease right-of-use assets, $4.6 million in unrealized losses on equity securities driven primarily by a decrease in the value of our investments, $0.8 million loss on our equity investment in the joint venture and $0.3 million in other non-cash items.

For the year ended December 31, 2020, net cash used in operating activities of $171.7 million consisted of a net loss of $224.2 million, partially offset by $36.1 million in adjustments for non-cash items and $16.4 million of cash provided by net working capital changes. Adjustments for non-cash items primarily consisted of $12.7 million in depreciation and amortization, an impairment of intangible assets totaling $10.7 million, $8.5 million in non-cash interest items related primarily to related-party promissory notes, $5.2 million in non-cash lease expense related to operating lease right-of-use assets, $2.2 million in stock-based compensation expense, a $1.4 million unrealized loss on non-marketable equity investment, and $1.2 million in other non-cash items, partially offset by a $2.9 million change in deferred tax liability, and a $2.9 million unrealized gain on equity securities. The changes in net working capital consisted primarily of increases related to $12.5 million in accrued expenses and other liabilities, $3.4 million with related parties, and $2.6 million in accounts payable, and a decrease related to $4.2 million in prepaid expenses and other current assets, partially offset by decreases related to $5.6 million in operating lease liabilities and $0.7 million in investment and other assets.

We have historically experienced negative cash flows from operating activities, with such negative cash flows likely to continue for the foreseeable future.

Investing Activities

For the year ended December 31, 2021, net cash used in investing activities was $84.9 million, which included $141.8 million of purchases of marketable debt securities and $33.6 million of purchases of property, plant and equipment, partially offset by cash inflows of $70.0 million from maturities and sales of marketable debt and equity securities, and $20.5 million in proceeds from the sale of 557 Doug St, LLC that were allocated to the book value of the property. Our investments in property, plant and equipment are primarily related to acquisitions of equipment that will be used for the manufacturing of our product candidates and expenditures related to the build out of our manufacturing facilities.

For the year ended December 31, 2020, net cash used in investing activities was $19.8 million, which included $91.8 million of purchases of marketable debt securities and $1.7 million of purchases of property, plant and equipment, partially offset by cash inflows of $73.7 million from maturities and sales of marketable debt securities.

We expect to accelerate our capital spending as we scale our GMP manufacturing capabilities, which will require significant capital for the foreseeable future.

Financing Activities

For the year ended December 31, 2021, net cash provided by financing activities was $505.4 million, which consisted of $338.5 million in net proceeds from issuances of related-party promissory notes, $164.5 million in net proceeds from the ATM offering, $5.5 million in proceeds from exercises of stock options and a $1.4 million capital contribution representing excess proceeds received over book value from the sale of 557 Doug St, LLC to an entity under common control. Net cash used in financing activities consisted of $4.1 million related to net share settlement of vested RSUs for payment of payroll tax withholding and a $0.4 million payment for contingent consideration.

For the year ended December 31, 2020, net cash provided by financing activities was $150.7 million, which consisted primarily of $86.3 million in net proceeds from an equity offering, $63.7 million in proceeds from issuances of related-party promissory notes and $1.2 million in proceeds from exercises of stock options, partially offset by $0.5 million related to net share settlement of vested RSUs for payment of payroll tax withholding.

Future Funding Requirements

From inception through the date of this Annual Report, we have generated minimal revenue, and we have no clinical products approved for commercial sale and have not generated any revenue from therapeutic and vaccine product candidates that are under development. We do not expect to generate significant revenue unless and until we obtain regulatory approval of and commercialize any of our product candidates, and we do not know when, or if, this will occur. In addition, we expect our operating expenses to significantly increase in connection with our ongoing development activities, particularly as we continue the research, development and clinical trials of, and seek regulatory approval for, our product candidates. We have also incurred and expect that we will continue to incur in the future additional costs associated with operating as a public company as well as costs related to future fundraising efforts. In addition, subject to obtaining regulatory approval of our product candidates, we expect to incur significant commercialization expenses for product sales, marketing, manufacturing and distribution. We anticipate that we will need substantial additional funding in connection with our continuing operations. We expect that our operating expenses will increase substantially if and as we:

•continue research and development, including preclinical and clinical development of our existing product candidates;

•potentially seek regulatory approval for our product candidates;

•seek to discover and develop additional product candidates;

•establish a commercialization infrastructure and scale up our manufacturing and distribution capabilities to commercialize any of our product candidates for which we may obtain regulatory approval;

•seek to comply with regulatory standards and laws;

•maintain, leverage and expand our intellectual property portfolio;

•hire clinical, manufacturing, scientific and other personnel to support our product candidates’ development and future commercialization efforts;

•add operational, financial and management information systems and personnel; and

•incur additional legal, accounting and other expenses in operating as a public company.

As a result of continuing anticipated operating cash outflows, we believe that substantial doubt exists regarding our ability to continue as a going concern without additional funding or financial support. However, we believe our existing cash, cash equivalents, and investments in marketable securities, together with capital to be raised through equity offerings (including the ATM) and our potential ability to borrow from affiliated entities, will be sufficient to fund our operations through at least the next 12 months following the issuance date of the consolidated financial statements based primarily upon our Executive Chairman and Global Chief Scientific and Medical Officer’s intent and ability to support our operations with additional funds, including loans from affiliated entities, as required, which we believe alleviates such doubt. We may also seek to sell additional equity, through one or more follow-on public offerings, or in separate financings, or obtain a credit facility. However, we may not be able to secure such external financing in a timely manner or on favorable terms. Without additional funds, we may choose to delay or reduce our operating or investment expenditures. Further, because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we may need additional funds to meet our needs sooner than planned.

We will need to obtain additional financing to fund our future operations, including completing the development and commercialization of our 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.

125

Table of Contents

Our future funding requirements will depend on many factors, including, but not limited to:

•progress, timing, number, scope and costs of researching and developing our product candidates and our ongoing, planned and potential clinical trials;

•time and cost of regulatory approvals;

•our ability to successfully commercialize any product candidates, if approved and the costs of such commercialization activities;

•revenue from product candidates that we may commercialize, if any, including the selling prices for such potential products and the availability of adequate third-party coverage and reimbursement for patients;

•cost of building, staffing and validating our own manufacturing facilities in the U.S., including having a product candidate successfully manufactured consistent with FDA and European Medicines Agency regulations;

•terms, timing and costs of our current and any potential future collaborations, business or product acquisitions, CVRs, milestones, royalties, licensing or other arrangements that we have established or may establish;

•time and cost necessary to respond to technological, regulatory, political and market developments; and

•costs of filing, prosecuting, maintaining, defending and enforcing any patent claims and other intellectual property rights.

Unless and until we can generate a sufficient amount of revenues, we may finance future cash needs through public or private equity offerings, license agreements, debt financings, collaborations, strategic alliances and marketing 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, including but not limited to the offering, issuance and sale by us of up to a maximum aggregate amount of $500.0 million of our common stock that may be issued and sold under the ATM. Although we made a decision to pause our ATM offering in the fourth quarter of 2021 after our $300.0 million promissory note financing with Nant Capital and do not have an active issuance notice with our sales agent, we expect to re-initiate activity at any time based on market dynamics and/or capital requirements. As of December 31, 2021, we had $330.8 million available for future stock issuances under the ATM. See Note 9, Stockholders’ Deficit, of the “Notes to Consolidated Financial Statements” that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

To the extent that we raise additional capital through the sale of equity or equity-linked securities, including convertible debt or through the ATM or other offerings, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a stockholder. The incurrence of additional indebtedness would result in increased fixed payment obligations and could involve certain restrictive covenants, 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. 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. 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.

Contractual Obligations

We have material cash requirements to pay related party affiliates and third parties under various contractual obligations discussed below:

•We are obligated to make payments to several related party affiliates under written agreements and other informal arrangements. We are also obligated to pay interest and to repay principal under our related-party notes payable. For information regarding our financing obligations, see Note 8, Related-Party Agreements—Related-Party Notes Payable, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•We are obligated to make payments under our operating leases, which primarily consist of facility leases. For information regarding our lease obligations, see Note 7, Commitments and Contingencies—Lease Arrangements, and Note 8, Related-Party Agreements, of the “Notes to Consolidated Financial Statements” that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•In connection with the acquisitions of Altor and VivaBioCell, we are obligated to pay contingent consideration upon the achievement of certain milestones. For information regarding our contingent consideration obligations, see Note 7, Commitments and Contingencies—Contingent Considerations Related to Business Combinations, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•We have contractual obligations to make payments to related party affiliates and third parties under our unconditional purchase arrangements. For information on these unconditional purchase obligations, see Note 7, Commitments and Contingencies—Contingent Consideration Related to Business Combinations, of the “Notes to Consolidated Financial Statements” that appears in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

•We have certain contractual commitments that are expected to be paid within one year, depending on the progress of build outs, completion of services, and the realization of milestones associated with third-party agreements. This amount totals $72.7 million and is primarily related to capital expenditures, open purchase orders as of December 31, 2021 for the acquisition of goods and services in the ordinary course of business, and near term up-front milestone payments to third parties.

•In addition, we have contractual commitments that are expected to be paid in fiscal year 2023 and beyond based on the achievement of various development, regulatory and commercial milestones for agreements with third parties. These payments may not be realized or may be modified and are contingent upon the occurrence of various future events, substantially all of which have a high degree of uncertainty of occurring. As of December 31, 2021, the maximum amount that may be payable related to these commitments is $570.7 million.

On February 14, 2022, we acquired a leasehold interest in the Dunkirk Facility. In connection with this lease, we committed to spend an aggregate of $1.52 billion on operational expenses during the initial 10-year term, and an additional $1.50 billion on operational expenses if we elect to renew the lease for the additional 10-year term. These amounts are not included in the discussion above. See “—Subsequent Events—Acquisition of cGMP ISO Class 5 Manufacturing Facility”.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of our consolidated financial statements requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses for the reporting period. On an ongoing basis, we evaluate our estimates, including those related to the valuation of equity-based awards, deferred income taxes and related valuation allowances, preclinical and clinical trial accruals, impairment assessments, contingent value right measurement and assessments, the measurement of right-of-use assets and lease liabilities, useful lives of long-lived assets, loss contingencies, fair value measurements, and the assessment of our ability to fund our operations for at least the next 12 months from the date of issuance of these financial statements. Actual results could differ from those estimates. While our significant accounting policies are more fully described in the notes accompanying our consolidated financial statements that appear in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report, we believe the following accounting policies to be the most critical in understanding the judgments and estimates we use in preparing our consolidated financial statements:

Revenue Recognition

We have 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 nonexclusive license agreements with a limited number of pharmaceutical and biotechnology companies grant them the right to use our cell lines and intellectual property for non-clinical use. These agreements generally include upfront fees and annual research license fees for such use, as well as commercial license fees for sales of the licensee products developed or manufactured using our intellectual property and cell lines. We have generated revenues from product sales of our proprietary GMP-in-a-Box bioreactors and related consumables to related parties. Additionally, we also generated revenues from grant programs.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation based on relative standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied.

Under our license agreements with customers, we typically promise to provide a license to use certain cell lines and related patents, the related know-how, and future research and development data that affect the license. We have concluded that these promises represent one performance obligation due to the highly interrelated nature of the promises. We provide the cell lines and know-how immediately upon entering into the contracts. Research and development data are provided throughout the term of the contract when and if available.

The license agreements may include non-refundable upfront payments, event-based milestone payments, sales-based royalty payments, or some combination of these. The event-based milestone payments represent variable consideration and we use the most likely amount method to estimate this variable consideration. Given the high degree of uncertainly around the achievement of these milestones, we do not recognize revenue from these milestone payments until the uncertainty associated with these payments is resolved. We currently estimate variable consideration related to milestone payments to be zero and, as such, no revenue has been recognized for milestone payments. We recognize revenue from sales-based royalty payments when or as the sales occur. On a quarterly basis, we re-evaluate our estimate of milestone variable consideration to determine whether any amount should be included in the transaction price and recorded in revenue prospectively.

We also have sold our proprietary GMP-in-a-Box bioreactors and related consumables to affiliated companies. The arrangements typically include delivery of bioreactors, consumables, and providing installation service and perpetual software licenses for using the equipment. We recognize revenue when customers obtain control and can benefit from the promised goods or services, generally upon installation of the bioreactors, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. Upfront payments and fees are recorded as deferred revenue upon receipt and recognized as revenue when we satisfy our performance obligations under these arrangements.

128

Table of Contents

Business Combinations

Business combinations are accounted for using the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations (ASC 805). These standards require that the total cost of acquisition be allocated to the tangible and intangible assets acquired and liabilities assumed based on their respective fair values at the date of acquisition, with the excess purchase price recorded as goodwill. The allocation of the purchase price is dependent upon certain valuations and other studies. Acquisition costs are expensed as incurred. Estimating fair value requires us to make significant judgments and assumptions.

Contingent consideration obligations incurred in connection with a business combination are recorded at their fair values on the acquisition date and re-measured at their fair values each subsequent reporting period until the related contingencies are resolved. The resulting changes in fair values are recorded as research and development expense, on the consolidated statements of operations and comprehensive loss. Changes in fair values reflect changes to our assumptions regarding probabilities of successful achievement of related milestones, the timing in which the milestones are expected to be achieved, and the discount rate used to estimate the fair value of the obligation.

Preclinical and Clinical Trial Accruals

As part of the process of preparing the consolidated financial statements, we are required to estimate expenses resulting from obligations under contracts with vendors, clinical research organizations and consultants. The financial terms of these contracts vary and may result in payment flows that do not match the periods over which materials or services are provided under such contracts.

We estimate clinical trial and research agreement-related expenses based on the services performed, pursuant to contracts with research institutions and clinical research organizations and other vendors that conduct clinical trials and research on our behalf. In accruing clinical and research-related fees, we estimate the time period over which services will be performed and activity expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, we will adjust the accrual accordingly. Payments made under these arrangements in advance of the receipt of the related services are recorded as prepaid expenses until the services are rendered.

Research and Development Costs

Major components of research and development costs include cash compensation and other personnel-related expenses, stock-based compensation, depreciation and amortization expense on research and development property and equipment and intangible assets, costs of preclinical studies, clinical trials costs, including CROs, and related clinical manufacturing, including CMOs, costs of drug development, costs of materials and supplies, facilities cost, overhead costs, regulatory and compliance costs, and fees paid to consultants and other entities that conduct certain research and development activities on our behalf. Costs incurred in research and development are expensed as incurred.

Included in research and development costs are clinical trial and research expenses based on the services performed pursuant to contracts with research institutions and clinical research organizations and other vendors that conduct clinical trials and research on our behalf. We record accruals for estimated costs under these contracts. When evaluating the adequacy of the accrued liabilities, we analyze the progress of the preclinical studies or clinical trials, including the phase or completion of events, invoices received, contracted costs and purchase orders. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period based on the facts and circumstances known at that time. Although we do not expect the estimates to be materially different from the amounts actually incurred, if the estimates of the status and timing of services performed differ from the actual status and timing of services performed, we may report amounts that are too high or too low in any particular period. Actual results could differ from our estimates. We adjust the accruals in the period when actual costs become known.

Stock-Based Compensation

We account for stock-based compensation under the provisions of ASC Topic 718, Compensation—Stock Compensation (ASC 718). We estimate fair value of each stock option award on the date of grant using the Black-Scholes option pricing model. The Black-Scholes model requires the use of highly subjective assumptions, including, but not limited to, expected stock price volatility over the term of the awards and the expected term of the stock options. We measure the fair value of an equity-classified award at the grant date and recognize the stock-based compensation expense over the period of vesting on the straight-line basis for our outstanding share awards that do not contain a performance condition. For awards subject to performance-based vesting conditions, we assess the probability of the individual milestones under the award being achieved and stock-based compensation expense is recognized over the service period using the graded vesting method once management believes the performance criteria is probable of being met. If factors change and we employ different assumptions, share-based compensation expense may differ significantly from what we have recorded in the past. For awards with service or performance conditions, we recognize the effect of forfeitures in compensation cost in the period that the award was forfeited.

Contingencies

We record accruals for loss contingencies to the extent that we conclude it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. We accrue for the best estimate of a loss within a range; however, if no estimate in the range is better than any other, then we accrue the minimum amount in the range. If we determine that a material loss is reasonably possible, we disclose the possible loss or range of loss, or that the amount of loss cannot be estimated at this time.

Because of the inherent uncertainty and unpredictability related to these matters, accruals are based on what we believe to be the best information available at the time of our assessment, including the legal facts and circumstances of the case, status of the proceedings, applicable law and the views of legal counsel. Upon the final resolution of such matters, it is possible that there may be a loss in excess of the amount recorded, and such amounts could have a material adverse effect on our results of operations, cash flows or financial position. We evaluate, on a quarterly basis, developments in legal proceedings and other matters that could cause a change in the potential amount of the liability recorded or of the range of potential losses disclosed. As of December 31, 2021, we recorded an accrual of $7.1 million contingency related to the dissenting share obligations in accrued and other current liabilities, on our consolidated balance sheets.

See further information in Note 7, Commitments and Contingencies, of the “Notes to Consolidated Financial Statements” included in Part II, Item 8. “Financial Statements and Supplementary Data” of this Annual Report.

Subsequent Events

Increase in Shares of Common Stock Authorized for Issuance

Effective February 1, 2022, ImmunityBio amended its Amended and Restated Certificate of Incorporation to increase the number of shares that the company is authorized to issue from 500,000,000 shares of common stock, $0.0001 par value per share, to 900,000,000 shares of common stock, $0.0001 par value per share. The number of shares of preferred stock, $0.0001 par value per share, that the company is authorized to issue remained unchanged at 20,000,000 shares.

Acquisition of cGMP ISO Class 5 Manufacturing Facility

On February 14, 2022, we acquired a leasehold interest in approximately 409,000 rentable square feet of cGMP ISO Class 5 pharmaceutical manufacturing space in western New York from Athenex. The facility provides us with a state-of-the-art biotech production center that substantially expands and diversifies our existing manufacturing capacity in the U.S.

We paid approximately $40.0 million to Athenex, and the leasehold interest in the Dunkirk Facility was transferred to us. Our annual lease payment will be $2.00 per year for an initial 10-year term, with an option to renew the lease under substantially the same terms and conditions for an additional 10-year term. As part of the transaction, we assumed obligations under various third-party agreements, and committed to spend $1.52 billion on operational expenses during the initial term, and an additional $1.50 billion on operational expenses if we elect to renew the lease for the additional 10-year term. We also committed to hiring 450 employees at the Dunkirk Facility within the first five years of operations, with 300 such employees to be hired within the first 2.5 years of operation. We are eligible for certain sales-tax exemption savings during the development of the Dunkirk Facility, and certain property tax savings over the next 20 years, subject to certain terms and conditions, including performance of certain of the obligations described above.
