NOTE 1—ORGANIZATION AND DESCRIPTION OF BUSINESS

Y-mAbs Therapeutics, Inc. (“we,” “us,” “our,” the “Company,” or “Y-mAbs”) is a commercial stage biopharmaceutical company focused on the development and commercialization of novel, antibody-based therapeutic products for the treatment of cancer. We are leveraging our proprietary antibody platforms and deep expertise in the field of antibodies to develop a broad portfolio of innovative medicines.

The Company is headquartered in New York and was incorporated on April 30, 2015 under the laws of the State of Delaware.

NOTE 2—BASIS OF PRESENTATION

The Company has incurred losses in almost all quarters since inception. Operations of the Company are subject to certain risks and uncertainties, including, among others, uncertainty of drug candidate development; technological uncertainty; uncertainty regarding patents and proprietary rights; uncertainty in obtaining the FDA approval in the United States and regulatory approval in other jurisdictions; marketing or sales capability or experience; uncertainty in getting adequate payor coverage and reimbursement; dependence on key personnel; compliance with government regulations and the need to obtain additional financing. The Company’s drug candidates currently under development will require significant additional research and development efforts, including extensive pre-clinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel infrastructure and extensive compliance reporting capabilities.

The Company’s drug candidates are in various stages of development. DANYELZA (naxitamab-gqgk) received accelerated approval by the FDA in November 2020, but there can be no assurance that the Company’s other research and development efforts will be successfully completed, that adequate protection for the Company’s intellectual property will be obtained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. Even if the Company’s product development and commercialization efforts are successful, it is uncertain when, if ever, the Company will generate significant revenue from product sales. The Company operates in an environment of rapid change in technology and substantial competition from pharmaceutical and biotechnology companies.

The Company’s consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities in the ordinary course of business. The Company has experienced negative cash flows from operations since inception, and had an accumulated deficit of $448,735,000 as of June 30, 2023, and $436,043,000 as of December 31, 2022. Through June 30, 2023, the Company has funded its operations primarily through proceeds from sales of shares of its common stock, including its initial public offering in September 2018 and its subsequent public offerings in November 2019 and February 2021, as well as additional funding from the sales of DANYELZA and from the sale of the Company’s Priority Review Voucher (“PRV”) obtained upon FDA approval of DANYELZA.

As of June 30, 2023, the Company had cash and cash equivalents of $87,909,000, and as of December 31, 2022, the Company had cash and cash equivalents of $105,762,000. As of the issuance date of the consolidated financial statements for the second quarter ended June 30, 2023, the Company expects that its cash and cash equivalents at June 30, 2023, will be sufficient to fund its operating expenses and capital expenditure requirements through at least the next 12 months, irrespective of whether any additional product approvals are obtained.

The Company may raise additional capital to fund future operations through the sale of its equity securities, incurring debt, entering into licensing or collaboration agreements with partners, grants or other sources of financing. These financing sources are in addition to successful commercialization of DANYELZA and our product candidates, for which the Company may obtain regulatory approval and marketing authorization. The Company’s commercialization

strategy may include working with a collaborator or distributor. Sufficient funds may not be available to the Company on attractive terms or at all when needed from equity or debt financing. If the Company is unable to obtain additional financing from these or other sources when needed, it will likely be necessary to take other actions to enhance the Company’s liquidity position which may include significantly reducing the current rate of spending through delaying or scaling back current operations, or suspending certain research and development programs and other operational programs.

The accompanying unaudited consolidated financial statements reflect the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information, Accounting Standards Codification (“ASC”) Topic 270-10 and the instructions to Form 10-Q. Accordingly, these consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. The unaudited interim consolidated financial statements include all adjustments (consisting only of normal recurring nature) necessary in the judgment of management for a fair statement of the results for the periods presented. All intercompany balances and transactions have been eliminated. The Company has evaluated subsequent events through the date of this filing. Operating results for the three- and six-month periods ended June 30, 2023, are not necessarily indicative of the results that may be expected for the year ending December 31, 2023, any other interim periods, or any future year or period. The December 31, 2022, consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. You should read these unaudited interim consolidated financial statements in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

NOTE 3—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company’s significant accounting policies are detailed in its Annual Report on Form 10-K for the year ended December 31, 2022.

Cash and Cash Equivalents

The Company considers all highly liquid instruments with original maturities of three months or less from date of purchase to be cash equivalents. All cash and cash equivalents are held in highly rated securities including a treasury money market fund, which is unrestricted as to withdrawal or use. To date, the Company has not experienced a loss on its cash and cash equivalents. The carrying amount of cash and cash equivalents approximates its fair value due to its short-term and liquid nature. The Company maintains cash balances in excess of insured limits. The Company monitors the financial performance, credit ratings and liquidity of the money market fund to timely assess and respond to any changes in the asset values of the fund. The Company does not anticipate any loss with respect to such cash balances.

Accounts Receivable, Net

The Company’s accounts receivable, net balance consists of amounts due from sales of our approved product, DANYELZA. Receivables from product sales are recorded net of allowances which generally include chargebacks, doubtful accounts, rebates, returns, and discounts. The allowance is based primarily on assessment of specific identifiable customer accounts considered at risk or uncollectible, as well as an analysis of current receivables aging and expected future write-offs. The Company has not historically experienced any significant credit losses. All customer accounts are actively managed, and no losses are currently expected.

Concentration of Credit Risk

The Company’s product sales are made through arrangements primarily with three national specialty distributors in the United States of America. As of June 30, 2023, the accounts receivable balances from such distributors totaled 71% of the Company’s outstanding accounts receivable. The remainder of the Company’s accounts receivable as of June 30, 2023 represented balances from international distribution partners. The Company has contractual payment terms with each of its customers and the Company monitors their financial performance, historical payment terms and credit worthiness to timely assess and respond to any changes in their credit profile.

Inventories

The Company values its inventories at the lower of cost or net realizable value on a first-in, first-out basis. The Company’s inventory cost includes amounts related to materials, third-party contract manufacturing, third-party packaging services, freight, labor costs for personnel involved in the manufacturing process, and indirect overhead costs. Raw and intermediate materials that may be utilized for both commercial and clinical programs are identical and given the alternative future use such amounts are initially classified as inventory. Amounts in inventory associated with clinical development programs are charged to research and development expense when the product enters the research and development process and can no longer be used for commercial purposes and, therefore, does not have an alternative future use.

The Company capitalizes inventory costs related to products to be sold in the ordinary course of business. The Company makes a determination of capitalizing inventory costs for a product based on, among other factors, status of regulatory approval, information regarding safety, efficacy and expectations relating to commercial sales and recoverability of costs. For DANYELZA, the Company commenced capitalization of inventory at the receipt of FDA approval.

The Company performs an assessment of the recoverability of capitalized inventory during each reporting period, and writes down any excess and obsolete inventories to their estimated realizable value in the period in which the impairment occurs. Such impairment charges, should they occur, are recorded within cost of goods sold. The determination of whether inventory costs will be realizable requires estimates by management. The Company had inventory write-downs totaling $456,000 in the three and six months ended June 30, 2023, which were recorded in cost of goods sold on the Consolidated Statements of Net Loss and Comprehensive Loss.

Fair Value Measurements

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e. an exit price). The accounting guidance includes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The three levels of the fair value hierarchy are as follows:

​

• Level 1 — Unadjusted quoted prices for identical assets or liabilities in active markets;

• Level 2 — Inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly for substantially the full term of the asset or liability; and

• Level 3 — Unobservable inputs for the asset or liability, which include management's own assumption about the assumptions market participants would use in pricing the asset or liability, including assumptions about risk.

Cash equivalents held in money market funds are valued using other significant observable inputs, which represent a Level 2 measurement within the fair value hierarchy. The Company has no other cash equivalents.

The following tables present the Company’s fair value hierarchy for its cash equivalents, which are measured at fair value on a recurring basis (in thousands):

​

Table of Contents

​

During the three and six months ended June 30, 2023, there were no transfers between Level 1, Level 2, and Level 3.

Operating Lease Right-of-Use Assets and Operating Lease Liabilities

The Company determines if an arrangement includes a lease at inception. Operating lease right-of-use assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of lease payments, the Company uses its estimated incremental borrowing rate based on information available at the lease commencement date. Because most of the Company’s leases do not provide an implicit rate of return, an incremental borrowing rate is used based on the information available at the commencement date in determining the present value of lease payments on an individual lease basis. The Company’s incremental borrowing rate for a lease is the estimated rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms.

The Company’s leases may include options to extend or terminate the lease which are included in the lease term when it is reasonably certain that it will exercise any such options. None of the Company’s leases contain any residual value guarantees. Lease expense is recognized on a straight-line basis over the expected lease term. Related variable lease costs incurred are not material to the Company.

The Company currently elects the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company will not recognize right-of-use assets or liabilities, and this includes not recognizing right-of-use assets or liabilities for existing short-term leases of those assets in transition. The Company also elects the practical expedient to not separate lease and non-lease components for all of our leases. The Company has made an accounting policy election to account for each separate lease component of a contract and its associated non-lease components as a single lease component. See the Lease Agreements section in NOTE 9—LICENSE AGREEMENTS AND COMMITMENTS for the related disclosures.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, net product revenues, the accrual for research and development expenses, the accrual of milestone and royalty payments, and the valuation of stock options. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.

Revenue Recognition

Product revenue, net

To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The company only applies the five-step model to arrangements that meet the definition of a contract with a

12

Table of Contents

customer under ASC 606, including when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the company assesses the goods or services promised within each contract, determines those that are performance obligations, and assesses whether each promised good or service is distinct. The company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Under the practical expedient permitted under Topic 606, the Company expenses incremental costs of obtaining a contract as and when incurred if the expected amortization period of the assets is one year or less. If there are multiple distinct performance obligations, we allocate the transaction price to each distinct performance obligation based on its relative standalone selling price. The Company also considers the intended benefit of the contract in assessing whether a promised good or service is separately identifiable from other promises in the contract. If a promised good or service is not distinct, the Company combines that good or service with other promised goods or services until it identifies a bundle of goods or services that is distinct. The standalone selling price is generally determined based on the prices charged to customers.

The Company recognizes revenue from sales of DANYELZA at a point in time when its customer is deemed to have obtained control of the product, which generally occurs upon receipt at the end-user hospital.

The amount of revenue the Company recognizes from sales of DANYELZA varies due to rebates, chargebacks and discounts provided under governmental and other programs, distribution-related fees and other sales-related deductions. In order to determine those deductions, the Company estimates, utilizing the expected value method, the amount of revenue that it will ultimately be entitled to. This estimate is based upon contracts with customers and government agencies, statutorily-defined discounts applicable to government-funded programs, estimated payor mix, and other relevant factors. Calculating these amounts involves estimates and judgments, and the Company reviews these estimates quarterly. If actual results vary from its original estimates, the Company will adjust these estimates quarterly, which would affect net product revenue and earnings in the period such variances occur.

The Company contracts with United States governmental agencies to ensure that DANYELZA will be eligible for coverage under the various programs administered by the agencies. The Company estimates the rebates and chargebacks to be provided and deducts these estimated amounts from its gross product revenues. These reserves are recorded in the same period the revenue is recognized, resulting in a reduction of product revenue and the establishment of accrued liabilities for the rebates and a reduction of accounts receivable for the chargebacks. The Company develops estimates for rebates and chargebacks based upon (i) the Company’s contracts with these agencies, (ii) the government-mandated discounts applicable to government-funded programs, and (iii) information obtained from hospitals and third-party consultants regarding the payor mix. The Company’s liability for these rebates and chargebacks mainly consists of claims for which invoices have not yet been received and paid. The Company does not maintain material levels of inventory in the wholesale or retail channel.

The Company provides invoice discounts on DANYELZA sales to its distributors for prompt payment and fees for distribution services and invoice discounts reduce the original accounts receivable balances. The payment terms for sales to distributors generally include a 2% discount for prompt payment or fees for distribution services which are based on contractual rates agreed with the respective distributors. Based on historical data and experiences with the distributors, the Company expects its distributors to earn these discounts and fees and deduct the full amount of these discounts and fees from its gross product revenue at the time such revenues are recognized.

13

Table of Contents

The Company offers its customers limited product return rights for damaged, defective, or expiring products. The Company estimates returns on sales of DANYELZA mainly based on information provided to the Company from the hospitals and distributors. The return reserves are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and establishment of an accrued liability.

​

In December 2022, the Company announced a distribution agreement with WEP Clinical Ltd., or WEP, in connection with an early access program for DANYELZA in Europe. There are no regulatory-based or sales-based milestone payments or royalty arrangements under this distribution agreement. The Company recognizes revenue when the customer obtains control of the product upon delivery to WEP. The Company invoices WEP based on the terms of the distribution agreement, where a portion is billed upon shipment of product and the unbilled portion is billed at a later date based on terms of the distribution agreement. The Company has an unconditional right to the unbilled portion of the receivable and the Company estimates that the receivable will be collected within one year and therefore has recorded the balance at June 30, 2023, within accounts receivable on the Consolidated Balance Sheets.

License revenue

In December 2020, the Company entered into a development and commercialization arrangement with SciClone International Pharmaceuticals Ltd., or SciClone, for certain indications of DANYELZA and omburtamab for Greater China, including Mainland China, Taiwan, Hong Kong and Macau. Based on the terms of the agreement, the Company may receive regulatory-based milestone payments up to $40,000,000 and sales-based milestone payments up to $60,000,000 and is entitled to royalties based upon the net sales generated by SciClone related to the product indications in the territory. In December 2022, the Company received a regulatory-based milestone payment of $15,000,000 for the conditional approval of DANYELZA in China. The Company determined that the achievement of the remaining regulatory-based milestones within the agreement are constrained as they are contingent upon regulatory approvals which are not within its control and therefore not deemed probable. The Company expects that the sales-based milestones and royalty payments will be recognized when the milestone is achieved or the related sales occur. The Company re-evaluates the transaction price each quarter and as uncertain events are resolved or other changes in circumstances occur, it assesses whether this resolves the constraint and it is appropriate to recognize revenue.

In November 2020, we entered into an exclusive license and distribution agreement for DANYELZA and omburtamab with Takeda Israel, a wholly-owned subsidiary of Takeda Pharmaceutical Company Limited covering the State of Israel, West Bank and Gaza Strip. Based on the terms of the arrangement, the Company may receive regulatory-based milestone payments up to $750,000, of which $250,000 has already been recognized, and sales-based milestone payments up to $500,000 and is entitled to royalties based upon the net sales generated by Takeda related to the product in the territory. The Company expects that the remaining regulatory-based and sales-based milestones will be recognized when the milestone is achieved, or the related sales occur.

In December 2020, the Company entered into a distribution agreement for DANYELZA and omburtamab with Swixx BioPharma AG for the Eastern European territories Bosnia & Herzegovina, Bulgaria, Croatia, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Russia, Serbia, Slovakia and Slovenia. There are no regulatory-based or sales-based milestone payments or royalty arrangements under this distribution agreement.

In May 2021, the Company entered into an exclusive distribution agreement with Adium Pharma S.A. (“Adium”) for Adium to be the exclusive distributor in Latin America of the Company’s antibodies omburtamab, if approved, and DANYELZA. Under the terms of the agreement, the Company may receive regulatory-based milestone payments up to an aggregate of $3,000,000. The Company received the first of these milestone payments totaling $1,000,000 in April 2022 upon the submission of the updated FDA Biologics License Application (“BLA”) dossier for DANYELZA. In addition, the Company is entitled to royalties based upon DANYELZA net sales generated by Adium in Latin America. The Company determined that the achievement of the remaining regulatory-based milestones within the agreement are constrained as they are contingent upon regulatory approvals which are not within the Company’s

14

Table of Contents

control and therefore not deemed probable. The agreement with Adium does not contain a regulatory-based milestone related to the Brazilian Health Regulatory Agency’s approval for marketing authorization, which was granted during the three months ended June 30, 2023. The Company expects that the sales-based milestones and royalty payments will be recognized when and if the milestones are achieved or the related sales occur. The Company reevaluates the transaction price each quarter and as uncertain events are resolved or other changes in circumstances occur, the Company assesses whether this resolves the constraint and it is appropriate to recognize revenue.

The Company did not recognize license revenue in the three and six months ended June 30, 2023.

Segment Information

The Company is engaged solely in the discovery, development, distribution and commercialization of novel antibody-based therapeutic products for the treatment of cancer. Accordingly, the Company has determined that it operates in one operating segment.

Recently Issued Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board, or FASB, and are adopted by the Company as of the specific effective date. The Company adopted ASU 2022-04, ASU 2022-02, ASU 2022-01 and ASU 2021-08 effective January 1, 2023, and the adoption of these new standards did not have a material impact on the Company’s consolidated financial statements or disclosures.

The Company has evaluated accounting pronouncements recently issued but not yet adopted and believes that these pronouncements do not apply to the Company’s operations and therefore will not have a material impact on the Company’s consolidated financial statements or disclosures.

NOTE 4—PRODUCT REVENUE, NET

The Company’s product revenue, net was generated from sales of DANYELZA and totaled $20,751,000 and $9,797,000 for the three months ended June 30, 2023 and 2022, respectively.

NOTE 5—NET LOSS PER SHARE

Basic net loss per share (“EPS”) is calculated by dividing net income or loss attributable to common stockholders by the weighted average common stock outstanding. Diluted EPS is calculated by adjusting weighted average common shares outstanding for the dilutive effect of common stock options and restricted stock units. In periods in which a net loss is recorded, no effect is given to potentially dilutive securities, since the effect would be antidilutive. Securities that could potentially dilute basic EPS in the future were not included in the computation of diluted EPS because to do so would have been antidilutive. The calculations of basic and diluted net loss per share are as follows (in thousands, except per share amounts):

Changes in noncurrent assets are reflected on the Consolidated Statements of Cash Flows within the caption of other assets.

NOTE 7—INTANGIBLE ASSETS, NET

The Company’s intangible assets, net as of June 30, 2023 totaled $2,809,000, which were net of $491,000 of accumulated amortization, and related to capitalized milestone payments made following FDA and other regulatory approvals and commercialization of DANYELZA.

NOTE 9—LICENSE AGREEMENTS AND COMMITMENTS

The Company has entered into three license agreements and certain other agreements with Memorial Sloan Kettering Cancer Center (“MSK”). The license agreements are the MSK License Agreement, dated August 20, 2015, between the Company and MSK (the “MSK License”), the License Agreement, dated November 13, 2017, between the Company and MSK (the “CD33 License Agreement”), and the License Agreement, dated April 15, 2020, between the Company, MSK and Massachusetts Institute of Technology (“MIT”) (the “SADA License Agreement”). Through the Settlement and Assumption and Assignment of the MSK License and Y-mAbs Sublicense Agreement, dated December 2, 2019, among MabVax Therapeutics Holdings, Inc. and MabVax Therapeutics, Inc., (together “MabVax”), the Company and MSK (the “SAAA”), the Company has established a direct license with MSK relating to the GD2-GD3 Vaccine, which was originally sublicensed by the Company in 2018 from MabVax. In addition, the Company entered the SADA License Agreement with MSK and Massachusetts Institute of Technology (“MIT”) in 2020. These license agreements with MSK and MIT grant the Company certain patent rights and intellectual property rights, and in consideration thereof, the Company agreed to make certain payments and issue shares of the Company’s common stock to MSK and MIT. Certain payments are contingent milestone and royalty payments, as disclosed in the table below. Amounts disclosed in NOTE 8—ACCRUED LIABILITIES for accrued milestone and royalty payments are inclusive of obligations under the MSK License Agreement, CD33 License Agreement, MabVax/MSK Agreement and SADA License Agreement, collectively.

In the past, the Company had defined MSK as a related-party under the Company’s related-party policy. During the three months ended June 30, 2023, the Company updated the related-party policy to remove MSK as a related-party as MSK does not participate on the Company’s Board of Directors, does not have a significant ownership in the Company and MSK is not in a position to exert decision making power. The Company has entered into several agreements with MSK, which include the MSK License Agreement, the SADA License Agreement, the CD33 License Agreement, and the MabVax Agreement, all as noted above.

The Company’s material license agreements are detailed in Note 9—License Agreements and Commitments to the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. There has not been substantive clinical activity or expenses incurred by the Company related to the CD33 License or the MabVax/MSK License Agreement for the three and six months ended June 30, 2023.

MSK License Agreement

The MSK License relates to intellectual property for DANYELZA and requires the Company to pay to MSK mid to high single-digit royalties based on annual net sales of licensed products or the performance of licensed services by the Company and the Company’s affiliates and sublicensees. The Company is required to pay annual minimum royalties of $80,000 over the royalty term, which amounts are non-refundable but are creditable against royalty

payments otherwise due thereunder. The Company is also obligated to pay to MSK certain clinical, regulatory and sales-based milestone payments under the MSK License, which payments become due upon achievement of the related clinical, regulatory or sales-based milestones. As product candidates developed using technology from the MSK License progress through clinical development, and potential regulatory approval and commercialization, certain of these clinical and regulatory milestone payments become due at the earlier of completion of the related milestone activity or the date indicated in the MSK License.

In addition to any milestone payments, to the extent the Company enters into sublicense arrangements, the Company is required to pay to MSK a percentage of certain payments that the Company receives from sublicensees of the rights licensed to the Company by MSK under the MSK License, which percentage will be based upon the achievement of certain clinical milestones. The Company has entered into sublicenses and distribution agreements related to DANYELZA and omburtamab under the MSK License with Takeda Israel, Swixx BioPharma AG and SciClone in 2020, with Adium in 2021, and with WEP in 2022.

The MSK License will expire, on a country-by-country basis, and on a licensed-product by licensed-product or licensed-service by licensed-service basis, on the later of (i) the expiration of the last to expire of the patents and patent applications covering such licensed product or service in such country, (ii) the expiration of any market exclusivity period granted by a regulatory authority for such licensed product or service in such country, or (iii) 15 years from the first commercial sale of such licensed product or service in such country.

MSK may terminate the MSK License upon prior written notice in the event of the Company’s uncured material breach, or upon prior written notice if such breach is of a payment obligation. MSK may also terminate the MSK License upon written notice in the event of the Company’s bankruptcy or insolvency or the Company’s conviction of a felony relating to the licensed products, or if the Company challenges the validity or enforceability of any licensed patent right. In addition, the Company has the right to terminate the MSK License in its entirety at will upon prior written notice to MSK, but if the Company has commenced the commercialization of licensed products and/or licensed services the Company can only terminate at will if the Company ceases all development and commercialization of such licensed products and/or licensed services.

The Company’s failure to meet certain conditions under the MSK License could cause the license related to such licensed product to be canceled and could result in termination of the MSK License by MSK.

SADA License Agreement

Pursuant to the SADA License Agreement, the Company was granted an exclusive worldwide, sublicensable license to MSK’s and MIT’s rights to certain patent and intellectual property to develop, make, and commercialize licensed products and to perform services for all therapeutic and diagnostic uses in the field of cancer diagnostics and cancer treatments using the SADA-BiDE Pre-targeted Radioimmunotherapy Platform (“SADA Technology”). At the time of entering into the arrangement, the Company assessed the licensing and other rights acquired and given the lack of outputs upon acquisition and that no employees were acquired, among other factors, the Company has concluded that the licensing rights represented an asset acquisition. The Company concluded that the technology acquired under the licensing arrangement had no alternative future use. This conclusion was based on consideration of the rights conveyed under the agreement, extent of further development necessary and presence of uncertainty prior to obtaining regulatory approval for any product.

The SADA License Agreement requires the Company to pay to MSK and MIT mid to high single-digit royalties based on annual net sales of licensed products or the performance of licensed services by the Company and its affiliates and sublicensees. The Company is obligated to pay annual minimum royalties of $40,000, increasing to $60,000 once a patent has been issued, over the royalty term, commencing on the tenth anniversary of the license agreement. These amounts are non-refundable but are creditable against royalty payments otherwise due under the SADA License Agreement. The Company is also obligated to pay MSK and MIT certain clinical, regulatory and sales-based milestone payments under the SADA License Agreement. As product candidates developed using technology from the SADA License Agreement progress through clinical development, and potential regulatory approval and

commercialization, certain of these clinical and regulatory milestone payments become due at the earlier of completion of the related milestone activity or the date indicated in the SADA License Agreement.

In addition to any milestone payments, to the extent the Company enters into sublicense arrangements, it is obligated to pay to MSK and MIT a percentage of certain payments received from sublicensees of the rights licensed to it by MSK and MIT, which percentage will be based upon the achievement of certain clinical milestones. The Company has not entered into any sublicenses related to the SADA License Agreement. For each of the constructs previously generated by MSK using the SADA Technology and sold for the Company by a sublicensee, the Company may pay sales milestones up to $60,000,000, in total, based on the achievement of various levels of cumulative net sales made by the sublicensee.

Failure by the Company to meet certain conditions under the arrangement could cause the related license to such licensed products to be canceled and could result in termination of the entire arrangement with MSK and MIT. In addition, the Company may terminate the SADA License Agreement with prior written notice.

Summary of Significant License Agreements and Related Commitments

The Company has the following significant license agreements and related commitments which include all obligations that have been paid or accrued for the three and six months ended June 30, 2023 and 2022, and as of June 30, 2023 and December 31, 2022 (in thousands):

​

Minimum royalties and certain clinical and regulatory milestones that become due based upon the passage of time under the CD33 License Agreement, the SADA Agreement and the MabVax/MSK License Agreement are excluded from the above table as the Company does not consider such obligations to be probable as of June 30, 2023.

The below table represents the maximum clinical, regulatory or sales-based milestones as reflected within the agreements, certain of which have been paid in prior periods or are accrued as presented in the table above (in thousands):

​

Research and development is inherently uncertain and should such research and development fail the MSK License Agreement, the CD33 License Agreement, the SADA License Agreement and the MabVax Agreement as well as the MabVax/Y-mAbs Sublicense are cancelable at the Company’s option. The Company will also consider the development risk and each party’s termination rights under the respective agreement when considering whether any clinical or regulatory-based milestone payments, certain of which also contain time-based payment requirements, are probable. The Company records milestones in the period in which the contingent liability is probable and the amount is reasonably estimable.

Table of Contents

The Company did not recognize any expense related to milestones under the SADA License Agreement during the three and six months ended June 30, 2023 and 2022, as no additional milestones were determined to be probable. The Company had $605,000, in accrued liabilities as of December 31, 2022, which was accrued upon entry into the arrangement in 2020. The Company made a payment of $605,000 in the quarter ended June 30, 2023 related to achievement of the milestone for dosing the first patient in the Phase 1 trial of GD2-SADA in April 2023, and did not have any accrued liabilities as of June 30, 2023 related to milestones under SADA License Agreement. During the second half of 2023, the Company anticipates having the necessary data for a further assessment of clinical progress to determine whether any other milestones under the agreement are deemed probable. The Company did not consider any other milestones under the SADA License Agreement to be probable as of June 30, 2023 and December 31, 2022.

Lease Agreements

In July 2019, the Company entered a development, manufacturing and supply agreement with SpectronRx in South Bend, Indiana, to secure access to clinical and commercial scale radiolabeling capacity for omburtamab. Under the terms of the agreement, SpectronRx had established a manufacturing unit designated for the Company within its existing facilities, at which both clinical and commercial supply of radiolabeled omburtamab could be produced. Since the Company possessed the right to substantially all the economic benefits and directs the use of the production area, the Company accounted for the payments related to the access to the manufacturing space under ASC 842 as an operating lease. The original term of the lease was two years from the commencement date of August 31, 2020, which was subsequently extended to December 2022. The Company entered into an additional one-month extension that terminated in January 2023 for a de minimis cost.

In February 2019, the Company entered into a lease agreement in connection with its 4,548 square feet laboratory in New Jersey. In December 2019, the Company expanded the space with an additional 235 square feet. The original term of the lease was three years from the date the Company occupied the premises, with an option to extend for an additional two years which was to expire in January 2024, which the Company exercised and had included in the determination of the related lease liability. In July 2023, the Company entered into a lease amendment to extend the term to February 2025. Fixed rent payable under the lease is approximately $177,000 per annum and is payable in equal monthly installments of approximately $15,000 per month.

In January 2018, the Company entered into a lease agreement in connection with its corporate headquarters in New York. The term of the lease was six years from the date the Company began to occupy the premises and the lease was to expire in April 2024. Fixed rent payable under the lease is approximately $384,000 per annum and is payable in equal monthly installments of approximately $32,000, which are recognized on a straight-line basis.

In February 2018, the Company entered into a lease agreement for certain office space in Denmark, which has been amended several times. The lease was renewed on November 1, 2021 with a four-year term that expires in November 2025. The lease is payable in monthly installments of approximately $41,000, which is recognized on a straight-line basis. In January 2023, the Company notified the landlord of its intention to reduce the leased premise as a result of the Company’s strategic restructuring, which was approved by the Company’s Board of Directors on January 4, 2023. The lease modification resulted in an immaterial charge in the six months ended June 30, 2023.

Total operating lease costs were $220,000 and $701,000 for the three months ended June 30, 2023 and 2022, respectively. Total operating lease costs were $560,000 and $1,406,000 for the six months ended June 30, 2023 and 2022, respectively. The decrease in operating lease costs in three and six months ended June 30, 2023 compared to the same periods in 2022 was due to the SpectronRx lease which we terminated in January 2023 as discussed above.

For the three months ended June 30, 2023, the operating lease expenses were recorded as $163,000 in research and development expense and $57,000 in selling, general and administrative expense. For the three months ended June 30, 2022, the expenses were recorded as $641,000 in research and development expense and $60,000 in selling, general and administrative expense.
