Commitments and Contingencies
Contingent Consideration Related to Business Combinations
VivaBioCell, S.p.A.
In April 2015, NantWorks, a related party, acquired a 100% interest in VivaBioCell through its wholly-owned subsidiary, VBC Holdings for $0.7 million, less working capital adjustments. In June 2015, NantWorks contributed its equity interest in VBC Holdings to the company, in exchange for cash consideration equal to its cost basis in the investment. VivaBioCell develops bioreactors and products based on cell culture and tissue engineering in Italy.
In connection with our acquisition of VBC, we are obligated to pay the former owners contingent consideration upon the achievement of certain milestones related to the GMP-in-a-Box technology. If a government agency unconditionally approves the GMP-in-a-Box technology for commercial sale (the regulatory milestone) in the future, we will be obligated to pay an additional approximately $2.3 million to the former owners.
Altor BioScience, LLC
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 the transaction was recorded as an asset acquisition, future CVR payments will be recorded when the corresponding events are probable of achievement or the consideration becomes payable. As of December 31, 2025, 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, 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.
Litigation
From time to time, we may be involved in various claims and legal proceedings relating to claims arising out of our operations. We are not currently a party to any legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business. If we are served with any such complaints, we will assess at that time any contingencies for which we may need to reserve. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.
Sorrento Therapeutics, Inc. Litigation
Sorrento, derivatively on behalf of NANTibody, filed an action in the Superior Court of California, Los Angeles County (the Superior Court) against the company’s subsidiary NantCell, Dr. Soon-Shiong, and Charles Kim. The action alleged that the defendants improperly caused NANTibody to acquire IgDraSol from NantPharma, LLC and sought to have the transaction undone and the purchase amount returned to NANTibody. In 2019, we filed a demurrer to several causes of action alleged in the Superior Court action, and Sorrento filed an amended complaint, eliminating Mr. Kim as a defendant and dropping the causes of action we had challenged in our demurrer. Trial had been set to commence in Sorrento’s Superior Court action on August 7, 2023, but on July 24, 2023 the Superior Court vacated the August 7, 2023 trial date at the parties’ request in light of the pending settlement discussed below.
Also in 2019, the company and Dr. Soon-Shiong filed cross-claims in the Superior Court action against Sorrento and its Chief Executive Officer Henry Ji, asserting claims for fraud, breach of contract, breach of the covenant of good faith and fair dealing, tortious interference with contract, unjust enrichment, and declaratory relief. Our claims alleged that Dr. Ji and Sorrento breached the terms of an exclusive license agreement between the company and Sorrento related to Sorrento’s antibody library and that Sorrento did not perform its obligations under the exclusive license agreement. The Superior Court ruled that the company’s claims should be pursued in arbitration and that Dr. Soon-Shiong’s claims could be pursued in Superior Court.
In 2019, the company, along with NANTibody, filed an arbitration against Sorrento and Dr. Ji asserting our claims relating to the exclusive license agreement. Sorrento filed counterclaims against the company and NANTibody in the arbitration. The hearings in the NANTibody arbitration commenced in April 2021 and concluded in early August 2021. After post-hearing briefing was concluded, the parties were notified on November 30, 2021 that the arbitrator in the NANTibody arbitration had passed away. A substitute arbitrator was appointed on February 25, 2022, and the parties worked with the substitute arbitrator to conclude the proceedings. Additional hearing sessions were held in May and July 2022, and summations took place on August 2, 2022.
On December 2, 2022, the arbitrator issued a final award finding that Sorrento had breached the two exclusive license agreements with NantCell and NANTibody. The arbitrator awarded NantCell approximately $156.8 million and NANTibody approximately $16.7 million, plus post-award interest accruing at a daily rate. On December 21, 2022, NantCell and NANTibody filed petitions in the Superior Court to confirm the arbitration award; on January 16, 2023, Sorrento filed a response to the petitions and moved to vacate the award. On February 7, 2023, after a hearing, the Superior Court entered orders confirming the arbitration award and denying Sorrento’s motion to vacate. The Superior Court entered judgments against Sorrento in the
aggregate amount of approximately $176.4 million plus 10% post-judgment interest, of which approximately $159.4 million was payable to NantCell, and the remainder of which was payable to NANTibody. On February 13, 2023, Sorrento informed counsel to the company that it had filed a Chapter 11 proceeding in the United States District Court for the Southern District of Texas, In re: Sorrento Therapeutics, Inc., et al., Case No. 23-90085 (DRJ), Docket Entry 810.
On June 6, 2023, Sorrento filed a motion in its Chapter 11 proceeding for entry of an order approving and implementing a mediation settlement reached with the company and other entities. The settlement involved two possible scenarios: Either, if Sorrento were to raise an amount needed to pay its debtor in possession lender and its unsecured creditors by August 31, 2023, Sorrento would pay those obligations, including the judgments held by NantCell and NANTibody, by 2:00 p.m. ET on August 31, 2023 and be free to proceed with pending litigation; or, failing that, the judgments would be released, the litigation claims would be released, including, without limitation, the Superior Court action discussed above, Sorrento would relinquish its interests in NANTibody and certain other entities, Sorrento would forfeit its rights to any payments from NantCell arising out of its antibody exclusive license agreement with NantCell (rights to PD-L1), and certain other provisions not impacting the company would be implemented as described in the motion. On August 14, 2023, the United States Bankruptcy Court for the Southern District of Texas issued an order approving the settlement described above, such that the settlement became binding on the parties. As of 2:00 p.m. ET on August 31, 2023, Sorrento had not paid the judgments held by NantCell and NANTibody. Accordingly, in relevant part to the company and NantCell, a mutual release of claims became effective such that the aforementioned judgments were released, the litigation claims were released including, without limitation, the derivative litigation against NantCell described above, Sorrento relinquished its interests in NANTibody, and Sorrento forfeited its rights to any payments from NantCell arising out of its antibody exclusive license agreement with NantCell, including any royalties associated with the company’s engineered NK cell therapy in Phase 2 clinical trials, PD-L1 t-haNK. As a result of the settlement, the parties filed dismissals of the litigation matters discussed above. After the settlement, the company’s ownership in NANTibody increased from 60% to 100%, and, as a result, the carrying amount of the noncontrolling interest of $4.2 million was adjusted and recognized in additional paid-in capital attributable to the company, on the consolidated statement of stockholders’ deficit.
Shenzhen Beike Biotechnology Co. Ltd. Arbitration
In 2020, we received a Request for Arbitration before the International Chamber of Commerce, International Court of Arbitration. The arbitration relates to a license, development, and commercialization agreement that Altor entered into with Beike in 2014, which was amended and restated in 2017, pursuant to which Altor granted to Beike an exclusive license to use, research, develop and commercialize products based on ANKTIVA in China for human therapeutic uses. In the arbitration, Beike is asserting a claim for breach of contract under the license agreement. Among other things, Beike alleges that we failed to use commercially reasonable efforts to deliver to Beike materials and data related to ANKTIVA. Beike is seeking specific performance and declaratory relief for the alleged breaches. On September 25, 2020, the parties entered into a standstill and tolling agreement (standstill agreement) under which, among other things, the parties affirmed they will perform certain of their obligations under the license agreement by specified dates and agreed that all deadlines in the arbitration are indefinitely extended. The standstill agreement could be terminated by any party on ten calendar days’ notice, and upon termination, the parties had the right to pursue claims arising from the license agreement in any appropriate tribunal. On March 20, 2023, we terminated the standstill agreement, and on April 11, 2023, Beike served an amended Request for Arbitration. We served an Answer and Counterclaims on May 19, 2023. Beike served a Reply to our counterclaims on June 21, 2023. Beike served its Statement of Claim on March 22, 2024, the company served its Statement of Defense and Counterclaim on June 21, 2024, and Beike served its Statement of Defense to the Counterclaim on August 2, 2024. After the parties completed discovery, Beike served its Reply and Defense to Counterclaim on January 17, 2025, we served our Rejoinder and Response to Defense to Counterclaim on March 14, 2025, and Beike served its Rejoinder on Counterclaim on March 28, 2025. The hearing in the arbitration was held from June 9, 2025 through June 13, 2025. Post-hearing submissions concluded in February 2026. It remains too early to evaluate the likely outcome of the case or to estimate any range of potential loss. We believe the claims asserted against the company lack merit.
Securities Class Action
On June 30, 2023, a putative securities class action complaint, captioned Salzman v. ImmunityBio, Inc. et al., No. 3:23-cv-01216-GCP-VET, was filed in the United States District Court for the Southern District of California against the company and three of its officers and/or directors, asserting violations of Sections 10(b) and 20(a) of the Exchange Act. Stemming from the company’s disclosure on May 11, 2023 that it had received an FDA CRL stating, among other things, that it could not approve the company’s BLA for its then product candidate, ANKTIVA with BCG for the treatment of adult patients with BCG-unresponsive NMIBC CIS with or without papillary tumors, in its present form due to deficiencies related to its pre-license inspection of the company’s third-party CMOs, the complaint alleges that the defendants had previously made materially false and misleading statements and/or omitted material adverse facts regarding its third-party CMOs and the prospects for regulatory approval of the BLA. The complaint did not specify the amount of damages being sought. On September 27, 2023, the court appointed a lead plaintiff, approved their selection of lead counsel, and re-captioned the case In re ImmunityBio, Inc. Securities Litigation, No. 3:23-cv-01216. On November 17, 2023, the lead plaintiff filed an amended complaint, which named the same defendants and asserted the same claims as the previous complaint. On January 8, 2024, the defendants filed a motion to dismiss the amended complaint. On June 20, 2024, the court issued an order granting in part and denying in part the motion to dismiss. On July 16, 2024, the lead plaintiff notified the court that he would proceed with his current pleading, and the defendants answered the complaint on August 29, 2024. On January 25, 2025, following a mediation and the parties’ agreement in principle to settle the securities class action for $10.5 million, the lead plaintiff filed an unopposed motion for preliminary approval of class action settlement. On March 17, 2025, the court granted preliminary approval of the settlement. On June 16, 2025, following a final approval hearing, the court granted final approval of the settlement. The lawsuit is now fully resolved.
As a result of the foregoing, the company recorded legal settlement expense of $10.5 million in selling, general and administrative expense, on the consolidated statement of operations during the year ended December 31, 2024 and a corresponding amount in accrued expenses and other liabilities, on the consolidated balance sheet. During the year ended December 31, 2025, the company settled in full the amount due under the settlement agreement. Of the $10.5 million, approximately $6.0 million were paid by the company’s insurers. The company paid the remaining $4.5 million under the settlement agreement.
Van Luven, Barbieri and Shin Derivative Actions
On October 29, 2024, a shareholder derivative action was filed in the United States District Court for the Southern District of California against the members of our Board of Directors and certain officers, captioned Van Luven v. Soon-Shiong et al., Case No. 3:24-cv-02014-GPCL-VET. The plaintiff purports to bring the action derivatively on behalf of ImmunityBio, and ImmunityBio is a nominal defendant to the action. Stemming from the company’s May 11, 2023 disclosure that it had received an FDA CRL stating, among other things, that it could not approve the company’s BLA for its then product candidate, ANKTIVA with BCG for the treatment of adult patients with BCG-unresponsive NMIBC CIS with or without papillary tumors, in its present form due to deficiencies related to its pre-license inspection of the company’s third-party CMOs, the derivative complaint alleges that the individual defendants authorized or permitted materially false and misleading statements and/or omitted material adverse facts regarding ImmunityBio’s third-party CMOs and the prospects for regulatory approval of the ANKTIVA BLA. The derivative complaint asserts claims for violations of Section 14(a) of the Exchange Act as well as claims for breach of fiduciary duty, unjust enrichment, and waste of corporate assets. The derivative complaint seeks unspecified damages on behalf of the company, disgorgement or restitution, declaratory relief, and an award of costs and expenses to the derivative plaintiff, including attorneys’ fees. The court entered an order extending the defendants’ deadline to respond to the complaint to May 30, 2025.
On February 25, 2025, a second shareholder derivative action was filed in the United States District Court for the Southern District of California against certain members of our Board of Directors and certain officers, captioned Barbieri v. Soon-Shiong, et al., Case No. 3:25-cv-00416-AGS-JLB. The plaintiff purports to bring the action derivatively on behalf of ImmunityBio, and ImmunityBio is a nominal defendant in the action. This lawsuit asserts substantially similar claims and allegations as Van Luven. The court entered an order extending the defendants’ deadline to respond to the complaint to May 30, 2025.
On February 26, 2025, a third shareholder derivative action was filed in the United States District Court for the Southern District of California against certain current and former members of our Board of Directors and certain officers, captioned Shin v. Soon-Shiong, et al., Case No. 3:25-cv-00423-JAH-DDL. The plaintiff purports to bring the action derivatively on behalf of ImmunityBio, and ImmunityBio is a nominal defendant in the action. This lawsuit asserts substantially similar claims and allegations as Van Luven. The court entered an order extending the defendants’ deadline to respond to the complaint to May 30, 2025.
On May 2, 2025, the court entered an order consolidating these three shareholder derivative actions. On May 22, 2025, the parties in the consolidated derivative action notified the court that they had entered into a Stipulation and Settlement Agreement to settle the consolidated derivative action for corporate governance reforms and attorneys’ fees. On November 6, 2025, the court entered an order and final judgment approving the settlement. As a result of the final judgment, the company was required to make various corporate governance modifications in which the company complied with.
Carlson Derivative Action
On November 20, 2024, a shareholder derivative action was filed in the Delaware Court of Chancery against the company’s Founder, Executive Chairman, Global Chief Scientific and Medical Officer and principal stockholder, Dr. Soon-Shiong, certain affiliates of Dr. Soon-Shiong, certain other members of management, and members of the company’s Board of Directors who serve on the Board of Directors’ Related Party Transaction Committee, captioned Carlson v. Soon-Shiong, et al., Case No. 2024-1195-VCL. The plaintiff purports to bring the action derivatively on behalf of ImmunityBio, and ImmunityBio is a nominal defendant to the action. The plaintiff alleges that the previously disclosed September 2023 financing transactions between the company and Dr. Soon-Shiong and his affiliates were not fair to the company. In particular, the plaintiff alleges that the transactions were timed to benefit Dr. Soon-Shiong and his affiliates during a temporary decline in the company’s stock price, resulting in an artificially low conversion price for certain convertible promissory notes that were among the transactions, when defendants knew the company’s stock price would increase following the company’s imminent resubmission of a BLA for, and the subsequent FDA approval of, ANKTIVA with BCG for the treatment of adult patients with BCG-unresponsive NMIBC CIS with or without papillary tumors. The complaint alleges that defendants breached their fiduciary duties by entering into these transactions at that time and on those terms, thereby unjustly enriching Dr. Soon-Shiong and his affiliates. The derivative complaint seeks unspecified damages on behalf of the company, corporate governance changes with respect to related-party transactions, and an award of costs and expenses to the derivative plaintiff, including attorneys’ fees. On February 17, 2025, the defendants filed a motion to dismiss the complaint.
On May 2, 2025, instead of filing an opposition to defendants’ motion to dismiss, the plaintiff filed an amended complaint. This amended complaint added certain additional members of the company’s Board of Directors as defendants but did not add new claims. On July 16, 2025, the defendants filed a motion to dismiss the amended complaint. On February 4, 2026, after complete briefing and oral argument, the court granted the defendants’ motion to dismiss. The plaintiff was not provided an opportunity to amend.
SRS/Altor Shareholder CVR Arbitration
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 ANKTIVA by December 31, 2022, and $304.0 million of contingent consideration upon calendar-year worldwide net sales of ANKTIVA exceeding $1.0 billion prior to December 31, 2026. As of December 31, 2025, Dr. Soon-Shiong, our Founder, Executive Chairman and Global Chief Scientific and Medical Officer, and his related party hold approximately $139.8 million of FDA approval CVRs and $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. Because the FDA did not approve our BLA on or before December 31, 2022, the first CVR milestone was not met.
On December 27, 2022, Shareholder Representative Services, LLC (SRS), in its capacity as shareholder representative on behalf of former Altor BioScience Corp. shareholders, sent the company’s subsidiary NantCell a notice of claims relating to the regulatory milestone CVR. The notice of claims asserted that SRS was exploring, and might pursue, claims on behalf of Altor shareholders for additional merger consideration in the amount of the $2.00 per share milestone payment under the regulatory CVR milestone. The notice stated that any such claim would be based on NantCell’s alleged failure to use commercially reasonable efforts to secure FDA approval of ANKTIVA on or before December 31, 2022. In a separate October 2022 letter, SRS requested that NantCell preserve all documents and information relating to its efforts to achieve milestones set forth in the regulatory milestone CVR, and requested that the company provide certain categories of documents under the information-sharing provisions of the CVR agreement.
After the company provided many of the requested documents, on September 29, 2023, SRS filed a demand for arbitration with JAMS, seeking to compel the company to produce additional documents identified in its October 2022 letter relating to its efforts to obtain FDA approval for ANKTIVA. The arbitration demand did not include any claims beyond SRS’s claim that it had a right to obtain additional documents, and sought a ruling that the company was obligated to provide additional documents. After the arbitrator issued a preliminary ruling regarding the scope of the company’s obligation to provide information under the CVR Agreements, the company produced additional documents responsive to SRS’s requests.
On August 27, 2025, several months after SRS’s document-access claim had been resolved, SRS requested leave to amend its JAMS arbitration demand to state a claim for breach of contract. SRS’s proposed amended demand alleged that the company and NantCell had failed to exercise commercially reasonable efforts to obtain FDA approval ANKTIVA on or before December 31, 2022. The JAMS arbitrator presiding over the document-access arbitration denied SRS’s motion for leave to amend its claims, and on September 26, 2025, the parties filed a joint stipulation asking that the JAMS document-access arbitration be closed.
After SRS’s motion for leave to amend was denied, on September 26, 2025, SRS sent the company a further notice of claims and essentially the same arbitration demand, asserting that the company had breached its obligations to exercise commercially reasonable efforts to achieve FDA approval of ANKTIVA on or before December 31, 2022. SRS’s arbitration demand seeks relief in the form of payment, in the amount of approximately $164.2 million plus interest exceeding $50.0 million, to former Altor shareholders not affiliated with Dr. Soon-Shiong. SRS filed its most recent arbitration demand with JAMS on November 5, 2025. The company filed its response on November 19, 2025, and an arbitrator was appointed on January 16, 2026. It remains too early to evaluate the likely outcome of the case or to estimate any range of potential loss. We believe the company exercised commercially reasonable efforts in its pursuit of FDA approval of ANKTIVA, and that the claims asserted against the company lack merit.
Dunkirk Facility Leasehold Interest
In 2022, we completed the acquisition of the Dunkirk Facility (approximately 409,000 rentable square feet) from Athenex. We believe this facility has the potential to provide us with a state-of-the-art biotech production center that will expand and diversify our existing manufacturing capacity in the U.S. and the ability to scale production associated with certain of our product candidates. The company accounted for the transaction as an asset acquisition because the Dunkirk Facility’s integrated set of assets and activities does not meet the definition of a business.
Upon the closing of the Dunkirk transaction, the company became the tenant of the Dunkirk Facility under the Fort Schuyler Management Corporation Lease, dated October 1, 2021 and as amended as of the February 14, 2022 closing date (as amended, the Dunkirk Lease), with the FSMC as landlord. The Dunkirk Facility, as well as certain equipment, is owned by the FSMC and is leased to us under the Dunkirk Lease. We believe that the Dunkirk Facility has construction needs that may require approximately 12 to 18 months to complete in order for it to be used as intended as a result of an ongoing dispute with the Dunkirk Facility’s general contractor and a stay in resolving the dispute related to Athenex’s ongoing bankruptcy proceedings.
In December 2025, we entered into a second amendment to the Dunkirk Lease (the “second amendment”). Under the second amendment, the annual lease payment was increased to $0.5 million for a revised lease term through December 31, 2028. The company has the option to purchase the Dunkirk Facility at $1.00 on either January 1, 2028, or January 1, 2029. The second amendment was accounted for as a modification of a single lease contract. The lease is classified as an operating lease. As of December 31, 2025, we recognized an operating right-of-use lease asset and lease liability of $1.4 million, respectively, on the consolidated balance sheet. See Note 12Lease Arrangements” for more information. The second amendment also removed the original spending obligations assumed from Athenex totaling $1.52 billion and replaced them with a series of spending targets totaling $55.0 million, including minimum of $40.0 million cumulative capital spending to be complied through December 31, 2028, and minimum of $5.0 million of annual operating spending to be complied from 2026 to 2028. As of December 31, 2025, we are in compliance with the requirements of such targets.
We also agreed to meet certain headcount targets by hiring at least 100 full-time employees by the end of the three-year term of the amended lease. If the option to purchase is exercised, we are required to hire at least 450 full-time employees by December 31, 2032 through December 31, 2033; and we are prohibited from conveying the premises for a five-year period without obtaining the prior written consent of FSMC and Empire State Development.
Unconditional Purchase Obligations
Unconditional purchase obligations are defined as an agreement to purchase goods or services that are enforceable and legally binding (non-cancelable, or cancellable only in certain circumstances). Estimated future minimum unconditional purchase obligations as of December 31, 2025 are as follows (in thousands):
Years Ending December 31,
20262027202820292030
Software license fees and installation costs$7,312 $916 $159 $93 $— 
Facilities services732 — — — — 
Reserved cGMP manufacturing capacity at
   third-party CMO facilities
396 — — — — 
Commercial launch and product services199 — — — — 
Other73 73 73 — — 
The purchase obligation amounts do not represent the entire anticipated purchases in the future but represent only those items for which we are contractually obligated. The majority of our goods and services are purchased as needed, with no unconditional commitment. For this reason, these amounts do not provide an indication of our expected future cash outflows related to purchases.
Commitments
During the year ended December 31, 2025, we did not enter into any significant contracts, other than those disclosed in these consolidated financial statements.
In addition to those commitments already disclosed, we have conditional contractual commitments that are expected to be paid in fiscal year 2027 and beyond based on royalties on potential future net sales or 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, 2025, the maximum amount that may be payable related to the various development, regulatory, and commercial milestones commitments is $40.8 million.

About Commitments Disclosures

Commitments and contingencies disclosures catalog a company's off-balance-sheet obligations and legal exposures — purchase commitments, guarantee arrangements, pending litigation, and regulatory proceedings. These items represent potential future cash outflows that may not appear as liabilities on the balance sheet until they become probable and estimable.

Key signals: litigation reserves and disclosed loss ranges quantify management's estimate of legal exposure, but unquantified "reasonably possible" losses often represent the larger risk. Watch for changes in language around pending cases — shifts from "remote" to "reasonably possible" or increases in estimated loss ranges signal deteriorating outcomes. Unconditional purchase obligations and take-or-pay contracts create fixed cost structures that reduce operational flexibility. Guarantee arrangements for subsidiaries or joint ventures can create cascading obligations. Compare the total commitment schedule against projected free cash flow to assess whether the company can meet its obligations without additional financing.
