MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion of our financial condition and results of operations should be read together with our selected consolidated financial data and the consolidated financial statements and related notes included elsewhere herein. This discussion contains forward-looking statements that involve risks and uncertainties. As a result of many factors including, but not limited to, those set forth under the sections entitled "Risk Factors" and "Forward-Looking Statements", our actual results may differ materially from those anticipated in such forward-looking statements.
For the discussion of our financial condition and results of operations for the year ended December 31, 2024 compared to the year ended December 31, 2023, please refer to Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on March 20, 2025.
Overview
We are a clinical-stage biopharmaceutical company focused on developing innovative antibody-based therapeutics for the treatment of cancer. We generate our pipeline of product candidates from our proprietary suite of antibody technology platforms. We are currently developing therapeutics utilizing multiple modalities, including antibody-drug conjugates (ADCs) and multi-specific antibodies (which we refer to as DART and TRIDENT molecules). The combination of our technology platforms and antibody engineering expertise has allowed us to generate promising product candidates - three of which have received marketing approval by the U.S. Food and Drug Administration (FDA) - and to enter into several strategic collaborations with global biopharmaceutical companies. These collaborations have provided us with over $1.6 billion of non-dilutive funding since our inception in 2000, and have enabled us to leverage the additional expertise of our collaborators to advance the development of multiple partnered product candidates. In addition, we operate a commercial-scale cGMP antibody manufacturing facility in our Maryland headquarters to support our clinical programs. We also provide outsourced contract development and manufacturing services to our collaborators and other third parties for commercial and clinical products to offset a significant portion of the operating costs of this facility.
We are currently advancing three proprietary product candidates in clinical development: lorigerlimab, a bispecific DART molecule that targets checkpoint inhibitors PD-1 and CTLA-4; MGC026, an ADC that targets B7-H3 and delivers a novel topoisomerase I inhibitor (TOP1i)-based linker-payload, and MGC028, an ADC that targets ADAM9 and delivers a novel TOP1i-based linker-payload. We are also actively developing multiple preclinical-stage ADC and next generation T-cell engager programs.
We and our partners are developing or commercializing product candidates for which we retain certain economic rights. These include three products approved by the FDA: ZYNYZ®(retifanlimab-dlwr), an anti-PD-1 monoclonal antibody (mAb) that we out-licensed; MARGENZA®(margetuximab-cmkb), an anti-HER2 mAb that we sold to a partner; and TZIELD®(teplizumab-mzwv), an anti-CD3 mAb that we sold to a partner. We are also collaborating with Gilead Sciences, Inc. (Gilead) on the development of MGD024, a bispecific DART antibody targeting CD123 and CD3 that utilizes our next-generation T-cell engager technology, as well as two additional undisclosed pre-clinical DART and TRIDENT development programs.
Our operations to date have concentrated on developing our technology platforms, identifying potential product candidates, undertaking preclinical studies, conducting clinical trials, developing collaborations, operating manufacturing facilities, business planning and raising capital. We only began generating revenues from the sale of products in 2021. We have financed our operations primarily through the public and private offerings of our securities, and collaborations with other biopharmaceutical companies. Although it is difficult to predict our funding requirements, we anticipate that our cash, cash equivalents and marketable securities as of December 31, 2025, combined with projected and anticipated future payments from our partners, and anticipated savings from our cost-reduction initiatives, will support our cash runway into late 2027. We have implemented, and will continue to evaluate and execute, various cost-saving measures that are intended to extend our financial runway while continuing to progress our pipeline.
Through December 31, 2025, we had an accumulated deficit of $1.2 billion. We expect that over the next several years this deficit will increase as we continue to incur research and development expense in connection with our ongoing activities and several clinical trials.
Macroeconomic Conditions
The global economy, credit markets and financial markets have and may continue to experience significant volatility as a result of significant worldwide events, including, fluctuating interest rates, and geopolitical upheaval and tariffs or other
restrictions imposed by the United States government or governments of other nations (collectively, the Macroeconomic Conditions). These Macroeconomic Conditions have and may continue to create supply chain disruptions, inventory disruptions, and fluctuations in economic growth, including fluctuations in employment rates, inflation, energy prices and consumer sentiment. It remains difficult to assess or predict the ultimate duration and economic impact of the Macroeconomic Conditions. Prolonged uncertainty with respect to Macroeconomic Conditions could cause further economic slowdown or cause other unpredictable events, each of which could adversely affect our business, results of operations or financial condition.
Collaborations
We pursue a balanced approach between product candidates that we develop ourselves and those that we develop with our collaborators. Under our strategic collaborations to date, we have received significant non-dilutive funding and continue to have rights to additional funding upon completion of certain research, achievement of key product development milestones and royalties and other payments upon the commercial sale of products. Our current collaborations include the following:
•Incyte Corporation (Incyte). We have an exclusive global collaboration and license agreement with Incyte for retifanlimab, a monoclonal antibody that inhibits PD-1 (Incyte License Agreement). Under this agreement, as amended, Incyte has obtained exclusive worldwide rights for the development and commercialization of retifanlimab in all indications, while we retain the right to develop our pipeline assets in combination with retifanlimab. We received an upfront payment of $150.0 million and milestone payments totaling $215.0 million from Incyte through December 31, 2025, including $100.0 million received in August 2024.We are eligible to receive up to an additional $210.0 millionin development and regulatory milestones and $330.0 million in commercial milestones. We are eligible for tiered royalties of 15% to 24% on any global net sales (see Note 10, Royalty Monetization Arrangement, in our consolidated financial statements for further information about ZYNYZ royalties), and we have the option to co-promote retifanlimab with Incyte. We retain the right to develop our pipeline assets in combination with retifanlimab, with Incyte commercializing retifanlimab and us commercializing our asset(s), if any such potential combinations are approved. We also have an agreement with Incyte under which we are entitled to manufacture a portion of Incyte's global commercial supply of retifanlimab (Incyte Commercial Supply Agreement).
•Gilead. In 2022, we and Gilead entered into an exclusive option and collaboration agreement (Gilead Agreement) to develop and commercialize MGD024 and create bispecific cancer antibodies using our DART and TRIDENT platforms and undertake their early development under a maximum of two separate bispecific cancer target research programs. Under the Gilead Agreement, we are continuing the ongoing phase 1 trial for MGD024 according to a development plan, during which Gilead will have the right to exercise an option granted to Gilead to obtain an exclusive license to develop and commercialize MGD024 and other bispecific antibodies of ours that bind CD123 and CD3(CD123 Option). The agreement also granted Gilead the right, within its first two years, to nominate a bispecific cancer target set for up to two research programs conducted by us and to exercise separate options to obtain an exclusive license for the development, commercialization and exploitation of molecules created under each research program (Research Program Option). As part of the Gilead Agreement, Gilead paid us a non-refundable upfront payment of $60.0 million and we are eligible to receive up to $1.7 billion in target nomination, option fees, and development, regulatory and commercial milestones, assuming Gilead exercises the CD123 Option and Research Program Option, successfully develops and commercializes MGD024 or other CD123 products developed under the agreement, and products result from the two additional research programs. Assuming exercise of the CD123 Option, we will also be eligible to receive tiered, low double-digit royalties on worldwide net sales of MGD024 (or other CD123 products developed under the agreement) and assuming exercise of the Research Program Option, a flat royalty on worldwide net sales of any products resulting from the two research programs. In 2023, Gilead nominated the first of the two research programs contemplated in the Gilead Agreement (First Research Program) and paid us a $15.7 million nomination fee. We granted Gilead a research license, and the parties agreed on a research plan for the First Research Program under which we will provide research and development services. In January 2024, the parties amended the Gilead Agreement to revise certain matters related to intellectual property in the performance of the research plans under the agreement. In June 2024, Gilead paid us variable consideration totaling $3.3 million upon achievement of a research plan milestone. On August 30, 2024, the parties entered into a second letter agreement under which Gilead will pay us to conduct certain research and which extends the period for Gilead to select its second research target combination. In November 2025, Gilead nominated the second of the two research programs contemplated in the
Gilead Agreement (Second Research Program) and we granted Gilead a research license. Gilead also exercised their exclusive option to obtain a license to exploit the research molecule and research product with respect to the Second Research Program. Gilead paid us a total of $25.0 million related to the nomination and option exercise in December 2025.
Financial Operations Overview
Revenue
Our revenue consists of the following:
•revenue from collaborative and other agreements which includes amounts recognized relating to upfront nonrefundable payments for licenses or options to obtain future licenses, amounts earned by performing development and manufacturing services, research and development funding and milestone payments earned under our collaboration and license agreements with our strategic collaborators;
•contract manufacturing revenue which is earned from providing development and manufacturing services to third parties and manufacturing their drug substance;
•product sales, net which reflects sales of MARGENZA. Product revenue is recorded net of applicable reserves for variable consideration, including discounts and other allowances. In November 2024, we sold global rights to MARGENZA to TerSera Therapeutics, LLC (TerSera) for an upfront payment of $40.0 million, and accordingly, no longer have product sales; and
•sales-based royalty revenue that is recognized when the related sales occur or when the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied.
Cost of Manufacturing Services
Cost of manufacturing services consists of the costs to provide manufacturing services to produce certain bulk drug substance under manufacturing and clinical supply agreements with third parties, including salaries and benefits and related stock-based compensation, materials, overhead and other related costs.
Research and Development Expense
Research and development expense consists of expenses incurred in performing research and development activities. These expenses include conducting preclinical experiments and studies, clinical trials, manufacturing efforts and regulatory filings for all product candidates, and other indirect expenses in support of our research and development activities. We capture research and development expense on a program-by-program basis for our product candidates and recognize these expenses as they are incurred. The following are items we include in research and development expense:
•employee-related expenses, such as salaries and benefits;
•employee-related overhead expenses, such as facilities and other allocated items;
•stock-based compensation expense to employees engaged in research and development activities;
•depreciation of laboratory and manufacturing equipment, computers and leasehold improvements;
•fees paid to consultants, subcontractors, clinical research organizations (CROs) and other third party vendors for work performed under our preclinical and clinical trials including, but not limited to, investigator grants, laboratory work and analysis, database management, statistical analysis, and other items;
•amounts paid to vendors and suppliers for laboratory supplies;
•internal and third party costs related to manufacturing clinical trial materials, including vialing, packaging and testing;
•license fees and other third party vendor payments related to in-licensed product candidates and technology; and
•costs related to compliance with regulatory requirements.
It is difficult to determine with certainty the duration and completion costs of our current or future preclinical programs and clinical trials of our product candidates, or if, when or to what extent we will generate revenues from the commercialization and sale of any of our product candidates that obtain regulatory approval. The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including the uncertainties of future clinical trials and preclinical studies, uncertainties in clinical trial enrollment rates and significant and changing government regulation. In addition, the probability of success for each product candidate will depend on numerous factors, including competition, manufacturing capability and commercial viability. We will determine which programs to pursue and how much to fund each program in response to the scientific and clinical success of each product candidate, as well as an assessment of each product candidate's commercial potential.
Selling, General and Administrative Expense
Selling, general and administrative expense consists of salaries and related benefit costs for employees in our executive, finance, legal and intellectual property, business development, human resources, information technology and other support functions. Selling, general and administrative expense also includes legal and professional fees and included costs incurred under the arrangement with our commercialization partner, Eversana Life Science Services, LLC in 2023 and 2024.
Critical Accounting Estimates
Our management's discussion and analysis of financial conditions and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The preparation of these consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheets and the reported amount of the revenue and expenses recorded during the reporting period. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable. We review and evaluate these estimates on an on-going basis. These assumptions and estimates form the basis for making judgments about the carrying values of assets and liabilities and amounts that have been recorded as revenues and expenses. Actual results and experiences may differ from these estimates. We did not make any material changes to these assumptions during the year ended December 31, 2025, and do not expect any material changes in the near term to the underlying assumptions. If we were to adjust our assumptions, the results of any material revisions would be reflected in the consolidated financial statements prospectively from the date of the change in estimate. Management considers an accounting estimate to be critical if:
•it requires a significant level of estimation uncertainty; and
•changes in the estimate are reasonably likely to have a material effect on our financial condition or results of operations.
While a summary of significant accounting policies is described fully in Note 2 in our consolidated financial statements, we believe that the following accounting policies are the most critical to assist you in fully understanding and evaluating our financial results and the effect of the estimates and judgments we used in preparing our consolidated financial statements.
Revenue Recognition
We recognize revenue under Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers, (ASC 606) when our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue recognition for arrangements that we determine are within the scope of ASC 606, management 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) we satisfy a performance obligation. 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.
Collaborative and Other Agreements
We enter into licensing agreements that are within the scope of ASC 606, under which we may license rights to research, develop, manufacture and commercialize our product candidates to third parties. The terms of these arrangements typically include payment to us of one or more of the following: non-refundable, upfront license fees; reimbursement of certain costs; customer option exercise fees; development, regulatory and commercial milestone payments; and royalties on net sales of licensed products. We may also enter into development and manufacturing service agreements with our collaborators.
For each arrangement that results in revenues, we identify all performance obligations, which may include a license to intellectual property and know-how, research and development activities, transition activities and/or manufacturing services. In order to determine the transaction price, in addition to any upfront payment, management estimates the amount of variable consideration at the outset of the contract either utilizing the expected value or most likely amount method, depending on the facts and circumstances relative to the contract. We constrain (reduce) the estimates of variable consideration such that it is probable that a significant reversal of previously recognized revenue will not occur. When determining if variable consideration should be constrained, management considers whether there are factors outside our control that could result in a significant reversal of revenue. In making these assessments, management considers the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period as required.
Once the estimated transaction price is established, amounts are allocated to the performance obligations that have been identified. The transaction price is generally allocated to each separate performance obligation on a relative standalone selling price basis. We must develop assumptions that require judgment to determine the standalone selling price in order to account for these agreements. To determine the standalone selling price, management's assumptions may include (i) the probability of obtaining marketing approval for the product candidate, (ii) estimates regarding the timing and the expected costs to develop and commercialize the product candidate, and (iii) estimates of future cash flows from potential product sales with respect to the product candidate. Standalone selling prices used to perform the initial allocation are not updated after contract inception. We do not include a financing component to its estimated transaction price at contract inception unless we estimate that certain performance obligations will not be satisfied within one year.
Amounts received prior to revenue recognition are recorded as deferred revenue. Amounts expected to be recognized as revenue within the 12 months following the balance sheet date are classified as current portion of deferred revenue in the accompanying consolidated balance sheets. Amounts not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue, net of current portion.
Licenses. When we grant a license to our intellectual property, we determine whether the nature of the intellectual property to which the customer will have rights is functional intellectual property (functional IP), which has significant standalone functionality, or symbolic intellectual property (symbolic IP) which does not have significant standalone functionality. Revenue from functional IP is recognized at the point in time when control of the distinct license is transferred to the customer. Revenue from symbolic IP is recognized over the access period to our intellectual property. If the license to our intellectual property is determined to be distinct from the other promises or performance obligations identified in the arrangement, we recognize revenue from non-refundable, upfront fees allocated to the license when the license is transferred to the customer and when (or as) the customer is able to use and benefit from the license. In assessing whether a promise or performance obligation is distinct from the other promises, we consider factors such as the research, development, manufacturing and commercialization capabilities of the licensee and the availability of the associated expertise in the general marketplace. In addition, we consider whether the licensee can benefit from a promise for its intended purpose without the receipt of the remaining promise, whether the value of the promise is dependent on the unsatisfied promise, whether there are other vendors that could provide the remaining promise, and whether it is separately identifiable from the remaining promise. For licenses that are combined with other promises, management utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. We evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition. The measure of progress, and thereby periods over which revenue should be recognized, are subject to estimates by management and may change over the course of the research and development and licensing agreement. Such a change could have a material impact on the amount of revenue we record in future periods.
Research, Development and/or Manufacturing Services. The promises under our agreements may include research and development or manufacturing services to be performed by us on behalf of the counterparty. If these services are determined to be distinct from the other promises or performance obligations identified in the arrangement, we recognize the transaction price allocated to these services as revenue over time based on an appropriate measure of progress when the performance by us does not create an asset with an alternative use and we have an enforceable right to payment for the performance completed to date. If these services are determined not to be distinct from the other promises or performance obligations identified in the arrangement, we recognize the transaction price allocated to the combined performance obligation as the related performance obligations are satisfied.
Customer Options. If an arrangement contains customer options, we evaluate whether the options are material rights because they allow the customer to acquire additional goods or services for free or at a discount. If the customer options are determined to represent a material right, the material right is recognized as a separate performance obligation at the outset of the arrangement. We allocate the transaction price to material rights based on the relative standalone selling price, which is
determined using assumptions regarding estimated costs, discount rates, post-option development timeline, the probability of technical and regulatory success and the probability that the customer will exercise the option. Amounts allocated to a material right are not recognized as revenue until, at the earliest, the option is exercised or expires. If the options are deemed not to be a material right, they are excluded as performance obligations at the outset of the arrangement.
Milestone Payments. At the inception of each arrangement that includes development milestone payments, management evaluates whether the milestones are considered probable of being achieved and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within our control or the licensee's control, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. We evaluate factors such as the scientific, clinical, regulatory, commercial, and other risks that must be overcome to achieve the particular milestone in making this assessment. There is considerable judgment involved in determining whether it is probable that a significant revenue reversal would not occur. At the end of each subsequent reporting period, management reevaluates the probability of achievement of all milestones subject to constraint and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.
Royalties. For arrangements that include sales-based royalties which are the result of a customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, we recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied.
We analyze our collaboration arrangements to assess whether such arrangements involve joint operating activities performed by parties who are both active participants in the activities and are both exposed to significant risks and rewards dependent on the commercial success of such activities. Such arrangements generally are within the scope of ASC 808, Collaborative Arrangements(ASC 808). While ASC 808 defines collaborative arrangements and provides guidance on income statement presentation, classification, and disclosures related to such arrangements, it does not address recognition and measurement matters, such as (1) determining the appropriate unit of accounting or (2) when the recognition criteria are met. Therefore, the accounting for these arrangements is either based on an analogy to other accounting literature or an accounting policy election by management. We account for certain components of the collaboration agreement that are reflective of a vendor-customer relationship (e.g., licensing arrangement) based on ASC 606. We account for other components based on a reasonable, rational and consistently applied accounting policy election. Reimbursements from the counter-party that are the result of a collaborative relationship with the counter-party, instead of a customer relationship, such as co-development activities, are recorded as a reduction to research and development expense as the services are performed.
Contract Manufacturing Revenue
We enter into agreements with third parties to manufacture their drug substance at our Good Manufacturing Practice (GMP) facility. The terms of these arrangements can include an upfront payment to us to reserve manufacturing capacity, scheduled payments during the manufacturing process and reimbursement for materials used to manufacture product. We recognize revenue over time on a straight-line basis as the manufacturing services are performed, as we believe that our efforts in providing the manufacturing services are incurred evenly throughout the performance period and therefore straight-line revenue recognition closely approximates the level of effort for the manufacturing services. Variable consideration relating to the reimbursed materials and other reimbursed costs incurred to manufacture product are allocated to the related manufacturing activities and are recognized as revenue as those activities occur.
Research and Development Expense, Including Clinical Trial Accruals/Expenses
Research and development expense consists of costs we incur for our own research and development activities and costs incurred by our collaborators under cost sharing arrangements. Research and development costs consist of salaries and benefits, including related stock-based compensation, laboratory supplies and facility costs, as well as fees paid to other entities that conduct certain research and development activities on our behalf, such as CROs, and the cost of acquiring and manufacturing clinical trial materials, including costs incurred under agreements with contract manufacturing organizations (CMOs). Research and development costs are expensed as incurred. We receive estimates from our collaborators when we are sharing development expenses, and use these estimates to record an increase or decrease in research and development expense, depending on how much we have each spent during the period.
Clinical trial expenses are a significant component of research and development expense, and we outsource a significant portion of these costs to third parties. Third party clinical trial expenses include investigator fees, site and patient
costs, CRO costs, costs for central laboratory testing, data management and CMO costs. The accrual for site and patient costs includes inputs such as estimates of patient enrollment, patient cycles incurred, clinical site activations, and other pass-through costs. These inputs are required to be estimated due to a lag in receiving the actual clinical information from third parties. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected on the consolidated balance sheets as a prepaid asset or accrued expenses. These third-party agreements are generally cancelable, and related costs are recorded as research and development expense as incurred. Non-refundable advance clinical payments for goods or services that will be used or rendered for future research and development activities are recorded as a prepaid asset and recognized as expense as the related goods are delivered or the related services areperformed.When evaluating the adequacy of the accrued expenses, we analyze progress of the studies, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates may be made in determining the accrued balances at the end of any reporting period. Actual results could differ from the estimates made. The historical clinical accrual estimates have not been materially different from the actual costs.
Liability related to the sale of future royalties and related interest expense
The liability related to future royalties is presented net of unamortized issuance costs on our consolidated balance sheets. Interest expense on the liability related to future royalties is recognized using the effective interest rate method over the life of the arrangement. We calculate an effective interest rate which will amortize our related obligation to zero over the anticipated repayment period. The liability related to future royalties and the related interest expense are based on our current estimates of future royalties expected to be received over the life of the arrangement, which we determine by using internal sales projections and external information from market data sources, which are considered Level 3 inputs. We periodically assess the expected payments and to the extent our estimates of future royalty payments are greater or less than previous estimates or the estimated timing of such payments is materially different than previous estimates, we will adjust the effective interest rate and recognize related non-cash interest expense on a prospective basis.

NM: Not Meaningful
The decrease of $32.7 million in revenue from collaborative and other agreements for the year ended December 31, 2025 compared to the year ended December 31, 2024 was primarily due to $100.0 million recognized from milestones under the Incyte License Agreement in 2024 compared to $50.0 million recognized from milestones under the Provention (Sanofi) Asset Purchase Agreement and $25.0 million from the Gilead Agreement in 2025.
Revenue from collaborative and other agreements may vary substantially from period to period depending on the progress made by our collaborators with their product candidates and the timing of milestones achieved under current agreements, and whether we enter into additional collaboration agreements.
Contract manufacturing revenue increased by $39.5 million for the year ended December 31, 2025 compared to the year ended December 31, 2024, reflecting increased production for external clients in 2025.
The decrease in product sales, net is due to the fact that we sold the global rights to MARGENZA to TerSera in November 2024, and accordingly, no longer have product sales.
Royalty revenue increased by $9.1 million for the year ended December 31, 2025 compared to December 31, 2024 due to higher sales of ZYNYZ. During 2025, $7.9 million of the royalty revenue was non-cash due to the sale of our royalty rights to Sagard Healthcare Partners (Sagard) in June 2025. See Note 10, Royalty Monetization Arrangement, to the consolidated financial statements for additional information.
Cost of Manufacturing Services
Cost of manufacturing services was $36.0 million and $11.5 million for the years ended December 31, 2025 and 2024, respectively. Cost of manufacturing services includes the costs to provide manufacturing services to our customers. The increase in the cost of manufacturing services is due to increased production for external clients in 2025. We expect cost of manufacturing services to vary from period to period based on the agreed-upon manufacturing schedule.

(a) Includes research and discovery projects, as well as early preclinical molecules and molecules not advanced to clinical development.
(b) Includes discontinued projects.
Research and development expense for the year ended December 31, 2025 decreased by $30.0 million compared to the year ended December 31, 2024. This decrease was primarily attributable to:
•decreased vobra duo costs due to the decision to discontinue further internal development of that program;
•decreased development costs related to the wind down of margetuximab activities after the sale of MARGENZA to TerSera; and
•decreased development, manufacturing and IND-enabling costs related to MGC028.
These decreases were partially offset by
•increased clinical trial costs related to MGC026 and MGC028; and
•increased development costs related to MGC030.
There are uncertainties associated with our research and development expenses for future periods which are impacted by multiple variables, including timing of wind down activities for recently closed studies and current and expected expenditures associated with our ongoing clinical studies.
Selling, General and Administrative Expense
Selling, general and administrative expenses were $39.2 million and $71.0 million for the years ended December 31, 2025 and 2024, respectively. The decrease is primarily due to lower stock-based compensation expense and reduced professional fees. The decrease in stock-based compensation expense was largely driven by additional stock-based compensation expense and accrued severance related to the separation agreement with our Chief Executive Officer recorded in 2024. The reduction in professional fees was largely driven by the cessation of commercialization activities for MARGENZA.
Gain on Sale of MARGENZA
In October 2024, we entered into an Asset Purchase and Sale Agreement (ASA) with TerSera Therapeutics, LLC (TerSera) which closed in November 2024. Under the terms of the ASA, we sold the global rights to MARGENZA, inclusive of our business of researching, developing, commercializing, manufacturing, packaging, distributing, promoting, marketing and selling the MARGENZA product, as well as using and licensing the intellectual property relating to MARGENZA. In addition to MARGENZA's intellectual property, TerSera also acquired all existing MARGENZA inventory. We recognized a gain of $36.3 million related to the ASA with TerSera during the year ended December 31, 2024.
Interest and Other Expense
In June 2025, we entered into a Purchase and Sale Agreement (Royalty Purchase Agreement) with Sagard, pursuant to which we sold to Sagard our right to receive royalties on global net sales of ZYNYZ (retifanlimab-dlwr) occurring on and after July 1, 2025 under our Incyte License Agreement, dated as of October 24, 2017, as amended. We are recognizing non-cash interest expense over the life of the Royalty Purchase Agreement, $8.3 million of which was recognized during the year ended December 31, 2025. The increase in Interest and Other Expense of $7.4 million from the year ended December 31, 2024 to the year ended December 31, 2025 is primarily due to this non-cash interest expense, partially offset by a decrease in other expense. See Note 10, Royalty Monetization Arrangement, for more information.

Operating Activities
Net cash used in operating activities consists of our net loss adjusted for non-cash items such as depreciation and amortization expense and stock-based compensation, gain on royalty monetization arrangement which is classified as a financing activity, gain on sale of MARGENZA which is classified as an investing activity, and changes in working capital. Net cash used in operating activities for the year ended December 31, 2025 benefited from $50.0 million in milestones from Sanofi and a $25.0 million payment related to the nomination and option exercise from Gilead. Net cash used in operating activities for the year ended December 31, 2024 benefited from a $100.0 million milestone payment received from Incyte under the Incyte License Agreement.
Investing Activities
Net cash used in investing activities during the year ended December 31, 2025 is primarily due to purchases of marketable securities, partially offset by maturities of marketable securities. Net cash provided by investing activities during the
year ended December 31, 2024 is primarily due to proceeds from the sale of MARGENZA to TerSera and maturities of marketable securities, partially offset by purchases of marketable securities.
Financing Activities
Net cash provided by financing activities for the year ended December 31, 2025 is primarily due to $70.0 million received from Sagard upon sale of our right to receive royalties on global net sales of ZYNYZ (retifanlimab-dlwr). Net cash provided by financing activities for the year ended December 31, 2024 includes proceeds from stock option exercises and ESPP purchases, offset by taxes paid related to net share settlement of equity awards.
Our multiple product candidates currently under development will require significant additional research and development efforts that include extensive preclinical studies and clinical testing, and regulatory approval prior to commercial use. Our future success is dependent on our ability to identify and develop our product candidates, and ultimately upon our ability to attain profitable operations. We have devoted substantially all of our financial resources and efforts to research and development and general and administrative expenses to support such research and development. Net losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders' equity and working capital, and accordingly, our ability to execute our future operating plans.
As a biotechnology company, we have primarily funded our operations with proceeds from the sale of our common stock in equity offerings and revenue from our multiple collaboration agreements. Management regularly reviews our available liquidity relative to our operating budget and forecast to monitor the sufficiency of our working capital and anticipates continuing to draw upon available sources of capital, including equity and debt instruments, to support our product development activities. There can be no assurances that new sources of capital will be available to us on commercially acceptable terms, if at all. Also, any future collaborations, strategic alliances and marketing, distribution or licensing arrangements may require us to give up some or all rights to a product or technology at less than its full potential value. If we are unable to enter into new arrangements or to perform under current or future agreements or obtain additional capital, we will assess our capital resources and may be required to delay, reduce the scope of, or eliminate one or more of our product research and development programs or clinical studies, and/or downsize our organization. Although it is difficult to predict our funding requirements, we anticipate that our cash, cash equivalents and marketable securities as of December 31, 2025, combined with projected and anticipated future payments from our partners, and anticipated savings from our cost-reduction initiatives, supports our cash runway into late 2027. We have implemented, and will continue to evaluate and execute, various cost-saving measures that are intended to extend our financial runway while continuing to progress our pipeline.
Material Cash Requirements
Our short-term and long-term material cash requirements consist of operational and capital expenditures, some of which contain contractual obligations. Our primary uses of cash relate to paying salaries and benefits, conducting research activities, administering clinical trials and providing the technology and facilities necessary to support our operations. The most significant contractual obligations are the operating leases at our facilities in Maryland. Our future minimum lease payments as of December 31, 2025 totaled $5.5 million related to short-term lease liabilities, and $59.8 million related to long-term lease liabilities. See Note 5, Commitments and Contingencies, in the Notes to the Financial Statements in this Annual Report on Form 10-K for additional information about our contractual obligations. We expect to fund these requirements with current cash, cash equivalents and marketable securities as well as anticipated and potential collaboration payments.
We do not have any off-balance sheet arrangements, as defined under the rules and regulations of the Securities and Exchange Commission.
