FORWARD-LOOKING STATEMENTS
This report includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements include statements that may relate to our plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs and other information that is not historical information. Many of these statements appear, in particular, under the headings "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Quarterly Report on Form 10-Q. Forward-looking statements can often be identified by the use of terminology such as "subject to", "believe", "anticipate", "plan", "expect", "intend", "estimate", "project", "may", "will", "should", "would", "could", "can", the negatives thereof, variations thereon and similar expressions, or by discussions of strategy.
All forward-looking statements, including, without limitation, our examination of historical operating trends, are based upon our current expectations and various assumptions. We believe there is a reasonable basis for our expectations and beliefs, but they are inherently uncertain. We may not realize our expectations, and our beliefs may not prove correct. Actual results could differ materially from those described or implied by such forward-looking statements. The following uncertainties and factors, among others (including those set forth under "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2021), could affect future performance and cause actual results to differ materially from those matters expressed in or implied by forward-looking statements:
our plans to develop and commercialize our product candidates;
the outcomes of our ongoing and planned clinical trials and the timing of those outcomes, including when clinical trials will be initiated or completed, and when data will be reported or regulatory filings will be made;
the timing of and our ability to obtain and maintain regulatory approvals for our product candidates and the labeling for any approved products;
our estimates regarding expenses, future revenue, capital requirements and needs for additional financing;
our ability to raise additional capital through the capital markets or through one or more corporate partnerships, equity offerings, debt financings, collaborations, licensing arrangements or asset sales and the availability of financing to fund the development of our product candidates;
our expectations regarding commercial prospects of or product revenues from MARGENZA and our product candidates if approved;
the severity and duration of the impact of the COVID-19 global pandemic on our business, operations, clinical programs, manufacturing, financial results and other aspects of our business;
our expectations regarding product candidates currently being developed by our collaborators;
our ability to enter into new collaborations or to identify additional products or product candidates with significant commercial potential that are consistent with our commercial objectives;
the potential benefits and future operation of our existing collaborations;
our ability to recover the investment in our manufacturing capabilities;
the rate and degree of market acceptance and clinical utility of our products;
our commercialization, marketing and manufacturing capabilities and strategy;
significant competition in our industry;
costs of litigation and the failure to successfully defend lawsuits and other claims against us and our expectations regarding the outcome of any regulatory or legal proceedings;
economic, political and other risks associated with our international operations;
our ability to receive research funding and achieve anticipated milestones under our collaborations;
our ability to protect and enforce patents and other intellectual property;
costs of compliance and our failure to comply with new and existing governmental regulations including, but not limited to, tax regulations;
loss or retirement of key members of management;
failure to successfully execute our growth strategy, including any delays in our planned future growth; and




our failure to maintain effective internal controls.
Consequently, forward-looking statements speak only as of the date that they are made and should be regarded solely as our current plans, estimates and beliefs. You should not place undue reliance on forward-looking statements. We cannot guarantee future results, events, levels of activity, performance or achievements. Except as required by law, we do not undertake and specifically decline any obligation to update, republish or revise forward-looking statements to reflect future events or circumstances or to reflect the occurrences of unanticipated events.

MACROGENICS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
1. Nature of Operations
Description of the business
MacroGenics, Inc. (the Company) is incorporated in the state of Delaware. The Company is a biopharmaceutical company focused on developing and commercializing innovative antibody-based therapeutics designed to modulate the human immune response for the treatment of cancer. The Company has a pipeline of product candidates being evaluated in clinical trials sponsored by MacroGenics or its collaborators. These product candidates include multiple immuno-oncology programs, some of which were created primarily using the Company’s proprietary, antibody-based technology platforms. The Company believes its product candidates have the potential, if approved for marketing by regulatory authorities, to have a meaningful effect on treating patients' unmet medical needs as monotherapy or, in some cases, in combination with other therapeutic agents. In March 2021, the Company and its commercialization partner commenced U.S. marketing of MARGENZA (margetuximab-cmkb), a human epidermal growth factor receptor 2 (HER2) receptor antagonist indicated, in combination with chemotherapy, for the treatment of adult patients with metastatic HER2-positive breast cancer who have received two or more prior anti-HER2 regimens, at least one of which was for metastatic disease.
Liquidity
The Company’s 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.
As a biotechnology company, the Company has primarily funded its operations with proceeds from the sale of its common stock in equity offerings, revenue from its multiple collaboration agreements, and contracts and grants from the National Institute of Allergy and Infectious Diseases (NIAID). Management regularly reviews the Company’s available liquidity relative to its operating budget and forecast to monitor the sufficiency of the Company’s working capital. Based on the Company’s most recent cash flow forecast, the Company believes its current resources are sufficient to fund its operating plans for a minimum of twelve months from the date that this Quarterly Report on Form 10-Q was filed. The Company plans to meet its future operating requirements by generating revenue from current and future strategic collaborations or other arrangements, and product sales. The Company anticipates continuing to draw upon available sources of capital, including equity and debt instruments, to support its product development activities. If the Company is unable to enter into new arrangements or to perform under current or future agreements or obtain additional capital, the Company will assess its capital resources and may be required to delay, reduce the scope of, or eliminate one or more of its product research and development programs or clinical studies, reduce other operating expenses, and/or downsize its organization.
Similar to the other risk factors pertinent to the Company's business, the COVID-19 pandemic and geopolitical tensions, including the ongoing military conflict between Russia and Ukraine and the related sanctions imposed against Russia, might unfavorably impact the Company's ability to generate such additional funding. Given the uncertainty in the rapidly changing market and economic conditions related to the COVID-19 pandemic and geopolitical tensions, the Company will continue to evaluate the nature and extent of the impact of these uncertainties on its business and financial position.
Basis of Presentation
The accompanying unaudited interim consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. The financial statements include all adjustments (consisting only of normal recurring adjustments) that the management of the Company believes are necessary for a fair presentation of the periods presented. These interim financial results are not necessarily indicative of results expected for the full fiscal year or for any subsequent interim period.

2. Summary of Significant Accounting Policies
During the three months ended March 31, 2022, there have been no material changes to the significant accounting policies previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.
Recent Accounting Pronouncements
There were no new accounting pronouncements that were issued or became effective since the issuance of the Company’s 2021 Annual Report on Form 10-K that had, or are expected to have, a material impact on its consolidated financial position, results of operations or cash flows.
3. Fair Value of Financial Instruments
The Company's financial instruments consist of cash and cash equivalents, marketable securities, accounts receivable, accounts payable and accrued expenses. The carrying amount of accounts receivable, accounts payable and accrued expenses are generally considered to be representative of their respective fair values because of their short-term nature.  The Company accounts for recurring and non-recurring fair value measurements in accordance with the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures (ASC 820). ASC 820 defines fair value, establishes a fair value hierarchy for assets and liabilities measured at fair value, and requires expanded disclosures about fair value measurements. The ASC 820 hierarchy ranks the quality of reliability of inputs, or assumptions, used in the determination of fair value and requires assets and liabilities carried at fair value to be classified and disclosed in one of the following three categories:
Level 1 - Fair value is determined by using unadjusted quoted prices that are available in active markets for identical assets and liabilities.
Level 2 - Fair value is determined by using inputs other than Level 1 quoted prices that are directly or indirectly observable. Inputs can include quoted prices for similar assets and liabilities in active markets or quoted prices for identical assets and liabilities in inactive markets. Related inputs can also include those used in valuation or other pricing models, such as interest rates and yield curves that can be corroborated by observable market data.
Level 3 - Fair value is determined by inputs that are unobservable and not corroborated by market data. Use of these inputs involves significant and subjective judgments to be made by a reporting entity - e.g., determining an appropriate adjustment to a discount factor for illiquidity associated with a given security.
The Company evaluates financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them each reporting period. This determination requires the Company to make subjective judgments as to the significance of inputs used in determining fair value and where such inputs lie within the ASC 820 hierarchy. There were no transfers between levels during the periods presented.

All available-for-sale marketable debt securities held as of March 31, 2022 and December 31, 2021 had contractual maturities of less than one year. All of the Company's available-for-sale marketable debt securities in an unrealized loss position as of March 31, 2022 and December 31, 2021 were in a loss position for less than twelve months.  Unrealized losses on

available-for-sale debt securities as of March 31, 2022 and December 31, 2021 were not significant and were primarily due to changes in interest rates, including market credit spreads, and not due to increased credit risks associated with specific securities. Accordingly, no allowance for credit losses related to the Company's available-for-sale debt securities was recorded for any periods presented. The Company does not intend to sell these investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity.
5. Inventory, Net
All of the Company's inventory relates to the manufacturing of MARGENZA. The following table sets forth the Company's net inventory (in thousands):
March 31, 2022December 31, 2021
Work in process$3,724 $3,929 
Finished goods874 459 
Total inventory, net$4,598 $4,388 

Prior to U.S. Food and Drug Administration (FDA) approval of MARGENZA in December 2020, the cost of materials and expenses associated with the manufacturing of MARGENZA were recorded as research and development expense. Subsequent to FDA approval, the Company began capitalizing inventory costs related to the manufacture of MARGENZA. The inventory balance as of March 31, 2022 and December 31, 2021 is net of a reserve of $2.0 million for unsaleable inventory.
6. Stockholders' Equity
In November 2020, the Company entered into a sales agreement (Sales Agreement) with an agent to sell, from time to time, shares of its common stock having an aggregate sales price of up to $100.0 million through an “at the market offering” (ATM Offering) as defined in Rule 415 under the Securities Act of 1933, as amended. The shares that were sold under the Sales Agreement were issued and sold pursuant to the Company's shelf registration statement on Form S-3 that was filed with the SEC on November 4, 2020. During the three months ended March 31, 2021, the Company sold 3,622,186 shares of common stock at a weighted average price per share of $27.60, resulting in net proceeds of approximately $98.2 million, net of underwriting discounts and commissions and other offering expenses.
In April 2021, the Company entered into Amendment No. 1 to the Sales Agreement which increases the amount of the Company’s common stock that can be sold by the Company through its agent under the ATM Offering, from an aggregate offering price of up to $100.0 million to an aggregate offering price of up to $300.0 million. The Company has not sold any shares of common stock related to Amendment No. 1 to the Sales Agreement as of March 31, 2022.
As part of the consideration for the rights granted to Zai Lab US LLC under the collaboration and license agreement described more fully in Note 7, Revenue, the Company and Zai Lab US LLC entered into a separate stock purchase agreement (Stock Purchase Agreement) in June 2021. Under this Stock Purchase Agreement, Zai Lab US LLC paid the Company approximately $30.0 million to purchase 958,467 newly issued shares of the Company's common stock, par value $0.01, at a fixed price of $31.30 which represented a $10.4 million premium over the share price on the Stock Purchase Agreement date.

7. Revenue
Collaborative and Other Agreements
Incyte Corporation
Incyte License Agreement
In 2017, the Company entered into an exclusive global collaboration and license agreement with Incyte Corporation (Incyte) for retifanlimab, an investigational monoclonal antibody that inhibits programmed cell death protein 1 (PD-1) (Incyte License Agreement). Incyte has obtained exclusive worldwide rights for the development and commercialization of retifanlimab in all indications, while the Company retains the right to develop its pipeline assets in combination with retifanlimab. Under the terms of the Incyte License Agreement, Incyte paid the Company an upfront payment of $150.0 million in 2017. In July 2021, Incyte announced that the FDA had issued a Complete Response Letter (CRL) regarding its Biologics License Application (BLA) for retifanlimab as a potential treatment for adult patients with locally advanced or metastatic squamous cell carcinoma of the anal canal. Incyte’s announcement indicated that the FDA determined that additional data are needed to demonstrate the clinical benefit of retifanlimab for the submitted indication, and that Incyte was reviewing the CRL
8



and would discuss next steps with the FDA. Incyte subsequently withdrew its European application for marketing authorization of retifanlimab for the treatment of squamous carcinoma of the anal canal. Incyte has stated it is pursuing development of retifanlimab in potentially registration-enabling studies beyond squamous cell carcinoma of the anal canal, including in patients with MSI-high endometrial cancer, Merkel cell carcinoma and non-small cell lung cancer. Incyte is also pursuing development of retifanlimab in combination with multiple product candidates from its pipeline.
Under the terms of the Incyte License Agreement, Incyte will lead global development of retifanlimab. Assuming successful development and commercialization by Incyte, the Company could receive up to approximately $420.0 million in development and regulatory milestones and up to $330.0 million in commercial milestones. From the inception of the Incyte License Agreement through March 31, 2022, the Company has recognized $70.0 million in development milestones under the Incyte License Agreement. If retifanlimab is approved and commercialized, the Company would be eligible to receive tiered royalties of 15% to 24% on any global net sales. The Company retains the right to develop its pipeline assets in combination with retifanlimab, with Incyte commercializing retifanlimab and the Company commercializing its asset(s), if any such potential combinations are approved. In addition, the Company retains the right to manufacture a portion of both companies' global commercial supply needs of retifanlimab, subject to the separate commercial supply agreement.
The Company evaluated the Incyte License Agreement under the provisions of Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606) and identified the following two performance obligations under the agreement: (i) the license of retifanlimab and (ii) the performance of certain clinical activities through a brief technology transfer period. The Company determined that the license and clinical activities are separate performance obligations because they are capable of being distinct, and are distinct in the context of the contract. The license has standalone functionality as it is sublicensable, Incyte has significant capabilities in performing clinical trials, and Incyte is capable of performing these activities without the Company's involvement; the Company performed the activities during the transfer period as a matter of convenience. The Company determined that the transaction price of the Incyte License Agreement at inception was $154.0 million, consisting of the consideration to which the Company was entitled in exchange for the license and an estimate of the consideration for clinical activities to be performed. The transaction price was allocated to each performance obligation based on their relative standalone selling price. The standalone selling price of the license was determined using the adjusted market assessment approach considering similar collaboration and license agreements. The standalone selling price for the agreed-upon clinical activities to be performed was determined using the expected cost approach based on similar arrangements the Company has with other parties. The potential development and regulatory milestone payments are fully constrained until the Company concludes that achievement of the milestone is probable and that recognition of revenue related to the milestone will not result in a significant reversal in amounts recognized in future periods, and as such have been excluded from the transaction price. Any consideration related to sales-based milestones and royalties will be recognized when the related sales occur, as they were determined to relate predominantly to the license granted to Incyte and, therefore, have also been excluded from the transaction price. The Company re-assesses the transaction price in each reporting period and when events whose outcomes are resolved or other changes in circumstances occur. From 2018 through March 31, 2022, it became probable that a significant reversal of cumulative revenue would not occur for development milestones totaling $70.0 million related to clinical and regulatory activities related to the further advancement of retifanlimab, including Incyte’s initiation of a Phase 3 clinical trial. Therefore, the associated consideration was added to the estimated transaction price and was recognized as revenue.

The Company recognized the $150.0 million allocated to the license when it satisfied its performance obligation and transferred the license to Incyte in 2017. The $4.0 million allocated to the clinical activities was recognized ratably as services were performed during 2017 and 2018. No revenue was recognized under the Incyte License Agreement during the three months ended March 31, 2022. During the three months ended March 31, 2021, $10.0 million in milestone revenue was recognized under the Incyte License Agreement.
Incyte Clinical Supply Agreement
In 2018, the Company entered into an agreement with Incyte, under which the Company is to perform development and manufacturing services for Incyte’s clinical needs of retifanlimab (Incyte Clinical Supply Agreement). The Company evaluated the Incyte Clinical Supply Agreement under ASC 606 and identified one performance obligation under the agreement: to perform services related to the development and manufacturing of the clinical supply of retifanlimab. The transaction price is based on the costs incurred to develop and manufacture drug product and drug substance, and is recognized over time as the services are provided, as the performance by the Company does not create an asset with an alternative use and the Company has an enforceable right to payment for the performance completed to date. The transaction price is being recognized using the input method reflecting the costs incurred (including resources consumed and labor hours expended) related to the manufacturing services. During the three months ended March 31, 2022 and 2021, the Company recognized revenue of $0.3 million and $0.1 million, respectively, for services performed under the Incyte Clinical Supply Agreement.
9



Incyte Commercial Supply Agreement
In 2020, the Company entered into an agreement with Incyte pursuant to which the Company is entitled to manufacture a portion of the global commercial supply needs for retifanlimab (Incyte Commercial Supply Agreement). Unless terminated earlier, the term of the Incyte Commercial Supply Agreement will expire upon the expiration of Incyte’s obligation to pay royalties under the Incyte License Agreement. The Company evaluated the Incyte Commercial Supply Agreement under ASC 606 and identified one performance obligation under the agreement: to perform services related to manufacturing the commercial supply of retifanlimab. The transaction price is based on a fixed price per batch of bulk drug substance to be manufactured and is recognized over time as the services are provided, as the performance by the Company does not create an asset with an alternative use and the Company has an enforceable right to payment for the performance completed to date. The transaction price will be recognized using the input method reflecting the costs incurred (including resources consumed and labor costs incurred) related to the manufacturing services. During the three months ended March 31, 2022 , the Company recognized de minimis revenue and during the three months ended March 31, 2021 the Company recognized $3.1 million for services performed under the Incyte Commercial Supply Agreement.
Zai Lab Limited
2018 Zai Lab Agreement
In 2018, the Company entered into a collaboration and license agreement with Zai Lab Limited (Zai Lab) under which Zai Lab obtained regional development and commercialization rights in mainland China, Hong Kong, Macau and Taiwan (Zai Lab’s territory) for (i) margetuximab, an immune-optimized anti-HER2 monoclonal antibody, (ii) tebotelimab, a bispecific DART® molecule designed to provide coordinate blockade of PD-1 and LAG-3 for the potential treatment of a range of solid tumors and hematological malignancies, and (iii) an undisclosed multi-specific TRIDENT molecule in preclinical development (2018 Zai Lab Agreement). Zai Lab will lead clinical development of these molecules in its territory.
Under the terms of the 2018 Zai Lab Agreement, Zai Lab paid the Company an upfront payment of $25.0 million ($22.5 million after netting value-added tax withholdings of $2.5 million). Assuming successful development and commercialization of margetuximab, tebotelimab and the TRIDENT molecule, the Company could receive up to $140.0 million in development and regulatory milestones, of which the Company has earned $9.0 million through March 31, 2022. In addition, Zai Lab would pay the Company tiered royalties at percentage rates of mid-teens to 20% for net sales of margetuximab in Zai Lab’s territory, mid-teens for net sales of tebotelimab in Zai Lab’s territory and 10% for net sales of the TRIDENT molecule in Zai Lab’s territory, which may be subject to adjustment in specified circumstances.
The Company evaluated the 2018 Zai Lab Agreement under the provisions of ASC 606 and identified the following material promises under the arrangement for each of the two product candidates, margetuximab and tebotelimab: (i) an exclusive license to develop and commercialize the product candidate in Zai Lab’s territory and (ii) certain research and development activities. The Company determined that each license and the related research and development activities were not distinct from one another, as the license has limited value without the performance of the research and development activities. As such, the Company determined that these promises should be combined into a single performance obligation for each product candidate. Activities related to margetuximab and tebotelimab are separate performance obligations from each other because they are capable of being distinct, and are distinct in the context of the contract. The Company evaluated the promises related to the TRIDENT molecule and determined they were immaterial in context of the contract, therefore there is no performance obligation related to that molecule. The Company determined that the net $22.5 million upfront payment from Zai Lab constituted the entirety of the consideration to be included in the transaction price as of the outset of the arrangement, and the transaction price was allocated to the two performance obligations based on their relative standalone selling price. The standalone selling price of the performance obligations was determined using the adjusted market assessment approach considering similar collaboration and license agreements. The potential development and regulatory milestone payments are fully constrained until the Company concludes that achievement of the milestone is probable, and that recognition of revenue related to the milestone will not result in a significant reversal in amounts recognized in future periods, and as such have been excluded from the transaction price. Any consideration related to royalties will be recognized if and when the related sales occur, as they were determined to relate predominantly to the license granted to Zai Lab and, therefore, have also been excluded from the transaction price.
The Company re-assesses the transaction price in each reporting period and when events whose outcomes are resolved or other changes in circumstances occur. From 2020 through March 31, 2022, it became probable that a significant reversal of cumulative revenue would not occur for development and regulatory milestones totaling $9.0 million. Therefore, the associated consideration was added to the estimated transaction price and was recognized as revenue. Of this $9.0 million, $5.0 million was recognized as revenue during the three months ended March 31, 2022. No revenue was recognized during the three months ended March 31, 2021 under the 2018 Zai Lab Agreement.

Zai Lab Clinical Supply Agreements
During 2019, the Company entered into two agreements under which the Company is to perform manufacturing services for Zai Lab’s clinical needs of margetuximab and tebotelimab (Zai Lab Clinical Supply Agreements). The Company evaluated the agreements under ASC 606 and determined that they should be accounted for as a single contract and identified two performance obligations within that contract: to perform services related to manufacturing the clinical supply of each of margetuximab and tebotelimab. The transaction price is based on the costs incurred to manufacture drug product and drug substance, and is recognized over time as the services are provided, as the performance by the Company does not create an asset with an alternative use and the Company has an enforceable right to payment for the performance completed to date. The transaction price is being recognized using the input method reflecting the costs incurred (including resources consumed and labor hours expended) related to the manufacturing service. During the three months ended March 31, 2022 and 2021, the Company recognized revenue of $0.2 million and $1.1 million, respectively, related to the Zai Lab Clinical Supply Agreements.
2021 Zai Lab Agreement

In June 2021, the Company entered into a collaboration and license agreement with Zai Lab US LLC (collectively with Zai Lab Limited referred herein as Zai Lab) involving collaboration programs and license-only programs (collectively, the Programs) encompassing four separate immuno-oncology molecules (2021 Zai Lab Agreement). The first program covers a lead research molecule that incorporates the Company’s DART platform and binds CD3 and an undisclosed target that is expressed in multiple solid tumors (Lead Program). The second program covers a target to be designated by the Company. For these programs, Zai Lab receives commercial rights in Greater China, Japan, and Korea while the Company receives commercial rights in all other territories. Under the Lead Program, Zai Lab received an option upon reaching a predefined clinical milestone to convert the regional arrangement into a global 50/50 profit share. If Zai Lab elects such option, Zai Lab is to pay the Company $85.0 million plus any research costs incurred by both parties as of the option election date. Zai Lab also obtained exclusive, global licenses from the Company to develop, manufacture and commercialize two additional molecules. Zai Lab granted the Company a worldwide, royalty-free, co-exclusive license to conduct the development activities allocated to the Company.
Under the terms of the 2021 Zai Lab Agreement, the Lead Program includes joint research and development services by both the Company and Zai Lab. For the other programs, Zai Lab can separately negotiate and agree with the Company to perform research and development services in the future.
In connection with the execution of the 2021 Zai Lab Agreement, Zai Lab paid the Company an upfront payment of $25.0 million. Additionally, as part of the consideration for the rights granted to Zai Lab under the 2021 Zai Lab Agreement, the Company and Zai Lab entered into the Stock Purchase Agreement whereby Zai Lab paid the Company approximately $30.0 million to purchase shares of the Company’s common stock, par value $0.01, at a fixed price of $31.30 which represented a $10.4 million premium over the share price on the Stock Purchase Agreement date.
Assuming successful development and commercialization of the Programs, the Company could receive up to approximately $800.0 million in development and regulatory milestones and $600.0 million in commercial milestones. In addition, Zai Lab would pay the Company tiered royalties at percentage rates of low double digit teens on annual net sales of certain specified products and of mid-single digits to low double digit teens on annual net sales of other specified products in Zai Lab’s territory, which may be subject to specified royalty reduction pursuant to the 2021 Zai Lab Agreement. Per the terms of the 2021 Zai Lab Agreement, the Company may also receive reimbursements from Zai Lab for certain research and development costs incurred by the Company.
The Company evaluated the 2021 Zai Lab Agreement under the provisions of ASC 606 and identified the following material promises: (i) exclusive licenses to develop, manufacture and commercialize the products in Zai Lab’s territory for each Program and (ii) certain research and development activities for the Lead Program. The Company determined that for the Lead Program, the license is not distinct from the related research and development activities, considering the early stage of development of the molecule and the Company’s significant expertise in this area and as such, the research and development services are expected to significantly modify and customize the license. Therefore, for the Lead Program, the license and the services were combined into a single performance obligation. Since the other programs each represent distinct intellectual property and there are no other services included in the 2021 Zai Lab Agreement related to these licenses, each license is considered to be a distinct performance obligation. As such, there are four performance obligations included in the 2021 Zai Lab Agreement.
The Company concluded that the estimated transaction price is $40.4 million, consisting of the $25.0 million upfront payment, the $10.4 million premium related to the purchase of the Company’s common stock, and the $5.0 million estimated reimbursement by Zai Lab for research and development activities for the Lead Program. The potential milestone payments
11



were deemed to be fully constrained until the Company concludes that achievement of the milestone is probable, and that recognition of revenue related to the milestone will not result in a significant reversal in amounts recognized in future periods, and as such have been excluded from the transaction price. Any consideration related to royalties will be recognized if and when the related sales occur, as they were determined to relate predominantly to the license granted to Zai Lab and, therefore, have also been excluded from the transaction price. The Company will re-assess the transaction price in each reporting period and when events whose outcomes are resolved or other changes in circumstances occur.
The transaction price of $40.4 million was then allocated to the four performance obligations based on their relative standalone selling price. The standalone selling price of the performance obligations was not directly observable; therefore, the Company estimated the standalone selling price using an adjusted market assessment approach, representing the amount that the Company believes a market participant is willing to pay for the product or service. The estimate was based on consideration of observable inputs, such as, values of other preclinical collaboration arrangements adjusted for the Company’s estimate of the probability of success for each Program.
Revenue related to the Lead Program license and related research and development services performance obligation is being recognized over time as the research and development activities are performed. The Company will utilize a cost-based input method according to costs incurred to date compared to estimated total costs. The transfer of control occurs over this time period and, in management’s judgment, is the best measure of progress towards satisfying the performance obligations. The Company recognized revenue allocated to the other programs at a point in time upon transfer of the licenses to Zai Lab in June 2021. During the three months ended March 31, 2022, the Company recognized revenue of $0.3 million under the 2021 Zai Lab Agreement. As of March 31, 2022, $16.2 million in revenue was deferred under the agreement, all of which was current. As of December 31, 2021, $16.1 million in revenue was deferred, all of which was current.
Janssen Biotech, Inc.
In December 2020, the Company entered into a research collaboration and license agreement with Janssen Biotech, Inc. (Janssen) to develop a novel DART molecule (Janssen Agreement). The research collaboration will incorporate the Company’s proprietary DART platform to enable simultaneous targeting of two undisclosed targets in a therapeutic area outside oncology. Under the terms of the Janssen Agreement, Janssen paid the Company an upfront payment of $20.0 million and will be responsible for funding all research and development expenses. The Company will also be eligible to receive up to $312.0 million in potential milestone payments and tiered royalties of up to 10% on worldwide product sales.
Subject to the terms of this agreement, the Company granted Janssen an exclusive, royalty-bearing license to develop, manufacture and commercialize the preclinical bispecific molecule and the Company will perform certain research and development activities during a specified research term. The Company evaluated the Janssen Agreement under the provisions of ASC 606 and identified the following material promises under the arrangement: (i) a license to develop the preclinical bispecific molecule and (ii) performing certain research and development activities during the research term. The Company determined that the license and research and development activities are separate performance obligations because they are capable of being distinct, and are distinct in the context of the contract. The license has standalone functionality as Janssen could benefit from the license on its own without the Company’s involvement during the research term. The Company determined that the transaction price of the Janssen Agreement at inception was $22.2 million, consisting of the consideration to which the Company was entitled in exchange for the license and an estimate of the consideration for research and development activities to be performed. The transaction price was allocated to each performance obligation based on their relative standalone selling price. The standalone selling price of the license was determined using the adjusted market assessment approach considering similar collaboration and license agreements as well as current market conditions. The standalone selling price for agreed-upon research and development activities to be performed was determined using the expected cost approach based on similar arrangements the Company has with other parties. This variable consideration is fully constrained until the Company begins its work under the performance obligation. The potential milestone payments are fully constrained until the Company concludes that achievement of the milestone is probable and that recognition of revenue related to the milestone will not result in a significant reversal in amounts recognized in future periods, and as such have been excluded from the transaction price. Any consideration related to sales-based milestones and royalties will be recognized when the related sales occur, as they were determined to relate predominantly to the license granted to Janssen and, therefore, have also been excluded from the transaction price. The Company re-assesses the transaction price in each reporting period and when events whose outcomes are resolved or other changes in circumstances occur.
The Company recognized the $20.0 million allocated to the license when it satisfied its performance obligation and transferred the license to Janssen in December 2020. The $2.2 million allocated to the research and development activities is being recognized over the Company’s involvement in the research term, which is estimated to be less than two years. The Company recognized revenue of $0.3 million for each of the three-month periods ended March 31, 2022 and 2021 for research and development activities performed under the Janssen Agreement.

I-Mab Biopharma
I-Mab License Agreement

In 2019, the Company entered into a collaboration and license agreement with I-Mab Biopharma (I-Mab) to develop and commercialize enoblituzumab, an immune-optimized, anti-B7-H3 monoclonal antibody that incorporates the Company's proprietary Fc Optimization technology platform (I-Mab License Agreement). I-Mab obtained regional development and commercialization rights in mainland China, Hong Kong, Macau and Taiwan (I-Mab's territory), will lead clinical development of enoblituzumab in its territories, and will participate in global studies conducted by the Company.
Under the terms of the I-Mab License Agreement, I-Mab paid the Company an upfront payment of $15.0 million. Assuming successful development and commercialization of enoblituzumab, the Company could receive up to $135.0 million in development and regulatory milestones, of which $5.0 million has been earned from the inception of the I-Mab License Agreement through March 31, 2022. In addition, I-Mab would pay the Company tiered royalties ranging from mid-teens to 20% on annual net sales in I-Mab's territory.
The Company evaluated the I-Mab License Agreement under the provisions of ASC 606 and identified the following material promises under the arrangement: (i) an exclusive license to develop and commercialize enoblituzumab in I-Mab’s territories, (ii) perform certain research and development activities and (iii) conduct a chronic toxicology study. The Company determined that the license and the related research and development activities were not distinct from one another, as the license has limited value without the performance of the research and development activities. As such, the Company determined that the license and related research and development activities should be combined into a single performance obligation. The Company determined that the $15.0 million upfront payment from I-Mab constituted the entirety of the consideration to be included in the transaction price as of the outset of the arrangement for the license and related research and development activities. The Company has also determined that the chronic toxicology study is distinct from the other promises and has estimated the variable consideration of that performance obligation to be approximately $1.0 million. I-Mab paid the Company for the cost of this study as the costs were incurred and I-Mab received a one-time credit of eighty percent of the total amount of such costs against the milestone achieved during 2021. The Company reassessed the transaction price as it became probable that a significant reversal of cumulative revenue would not occur for a $5.0 million milestone ($4.5 million after netting a one-time credit as described above) related to development progress of enoblituzumab, therefore the associated consideration was added to the estimated transaction price and was recognized as revenue during 2021. The potential development and regulatory milestone payments are fully constrained until the Company concludes that achievement of the milestone is probable, and that recognition of revenue related to the milestone will not result in a significant reversal in amounts recognized in future periods, and as such have been excluded from the transaction price. Any consideration related to royalties will be recognized if and when the related sales occur, as they were determined to relate predominantly to the license granted to I-Mab and, therefore, have also been excluded from the transaction price. The Company re-assesses the transaction price in each reporting period and when events whose outcomes are resolved or other changes in circumstances occur.
    Revenue under the I-Mab License Agreement is being recognized using a cost-based input method according to costs incurred to date compared to estimated total costs. The transfer of control occurs over this time period and, in management’s judgment, is the best measure of progress towards satisfying the performance obligations. During the three months ended March 31, 2022 and 2021, the Company recognized revenue of $0.2 million and $0.6 million, respectively, under the I-Mab License Agreement. As of March 31, 2022, $4.4 million in revenue was deferred under the I-Mab License Agreement, all of which was current. As of December 31, 2021, $4.5 million in revenue was deferred under the I-Mab License Agreement, all of which was current.
I-Mab Clinical Supply Agreement

In October 2021, the Company entered into an agreement under which the Company is to perform development and manufacturing services for I-Mab’s clinical needs of enoblituzumab (I-Mab Clinical Supply Agreement). The Company evaluated this agreement under ASC 606 and identified one performance obligation under the agreement: to perform services related to the development and manufacturing of the clinical supply of enoblituzumab. The transaction price is based on the costs incurred to develop and manufacture drug product and drug substance, and is recognized over time as the services are provided, as the performance by the Company does not create an asset with an alternative use and the Company has an enforceable right to payment for the performance completed to date. The transaction price will be recognized using the input method reflecting the costs incurred (including resources consumed and labor hours expended) related to the manufacturing services. During the three months ended March 31, 2022, the Company recognized revenue of $0.9 million for research and development activities performed under the I-Mab Clinical Supply Agreement.
Manufacturing Services Agreement
13



Incyte
In January 2022, the Company entered into a Manufacturing and Clinical Supply Agreement with Incyte (Incyte Manufacturing and Clinical Supply Agreement) to provide manufacturing services to produce certain Incyte bulk drug substance over a three-year period at one of the Company’s manufacturing facilities. Under the terms of the Incyte Manufacturing and Clinical Supply Agreement, the Company received an upfront payment of $10.0 million and is eligible to receive annual fixed payments paid quarterly over the term of the contract totaling $14.4 million. The Company will also be reimbursed for materials used to manufacture product as well as other costs incurred to provide manufacturing services.
The Company evaluated the Incyte Manufacturing and Clinical Supply Agreement under the provisions of ASC 606 and identified one performance obligation to provide manufacturing runs to Incyte, as and when requested by Incyte, over the term of the contract that is part of a series of goods and services. The Company determined that the transaction price at inception consists of the upfront payment received of $10.0 million and the annual fixed payments totaling $14.4 million. The Company will recognize revenue over time on a straight-line basis as the manufacturing services are provided to Incyte, as the Company determined that its efforts in providing the manufacturing services will be 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 for Incyte will be allocated to the related manufacturing activities and will be recognized as revenue as those activities occur. Materials purchased by the Company to manufacture the product for Incyte are considered costs to fulfill a contract and will be capitalized and expensed as the materials are used to provide the manufacturing services.
There was no revenue recognized under the Incyte Manufacturing and Clinical Supply Agreement during the three months ended March 31, 2022. As of March 31, 2022, $11.2 million in revenue was deferred under this agreement, $4.8 million of which was current and $6.4 million of which was non-current.
Government Agreement
NIAID Contract
The Company entered into a contract with National Institute of Allergy and Infectious Diseases (NIAID), effective as of September 15, 2015, to perform product development and to advance up to two DART molecules, MGD014 and MGD020 (NIAID Contract). Under the NIAID Contract, the Company will develop these product candidates for Phase 1/2 clinical trials as therapeutic agents, in combination with latency reversing treatments, to deplete cells infected with human immunodeficiency virus (HIV) infection. NIAID does not receive goods or services from the Company under this contract, therefore the Company does not consider NIAID to be a customer and concluded this contract is outside the scope of ASC 606.
Since the inception of the NIAID Contract, NIAID has exercised the two options contemplated in the original contract and executed modifications such that the total funded contract value as of March 31, 2022 is $25.1 million. In addition, the most recent modification changed the period of performance under the NIAID Contract to end in July 2023. During the three months ended March 31, 2022 and 2021, the Company recognized revenue under the NIAID Contract of $0.4 million and $0.8 million, respectively.
8. Stock-Based Compensation
Employee Stock Purchase Plan
In May 2017, the Company’s stockholders approved the 2016 Employee Stock Purchase Plan (the 2016 ESPP). The 2016 ESPP is structured as a qualified employee stock purchase plan under Section 423 of the Internal Revenue Code of 1986, as amended (IRC), and is not subject to the provisions of the Employee Retirement Income Security Act of 1974. The Company reserved 800,000 shares of common stock for issuance under the 2016 ESPP. The 2016 ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 10% of their eligible compensation, subject to any plan limitations. The 2016 ESPP provides for six-month offering periods ending on May 31 and November 30 of each year. At the end of each offering period, employees are able to purchase shares at 85% of the fair market value of the Company’s common stock on the last day of the offering period. During the three months ended March 31, 2022, no shares of common stock were purchased under the 2016 ESPP.
Employee Stock Option Plans
Effective February 2003, the Company implemented the 2003 Equity Incentive Plan (2003 Plan), and it was amended and approved by the Company's stockholders in 2005. Stock options granted under the 2003 Plan may be either incentive stock options as defined by the IRC, or non-qualified stock options. In 2013, the 2003 Plan was terminated, and no further awards may be issued under the plan. Any shares of common stock subject to awards under the 2003 Plan that expire, terminate, or are
14



otherwise surrendered, canceled, forfeited or repurchased without having been fully exercised, or resulting in any common stock being issued, will become available for issuance under the 2013 Stock Incentive Plan (2013 Plan), up to a specified number of shares.  As of March 31, 2022, under the 2003 Plan, there were options to purchase an aggregate of 160,357 shares of common stock outstanding.
In October 2013, the Company implemented the 2013 Plan.  The 2013 Plan provides for the grant of stock options and other stock-based awards, as well as cash-based performance awards.  The number of shares of common stock reserved for issuance under the 2013 Plan will automatically increase on January 1 of each year from January 1, 2014 through and including January 1, 2023, by the lesser of (a) 1,960,168 shares, (b) 4.0% of the total number of shares of common stock outstanding on December 31 of the preceding calendar year, or (c) the number of shares of common stock determined by the Company's Board of Directors. During the three months ended March 31, 2022, the maximum number of shares of common stock authorized to be issued by the Company under the 2013 Plan was increased to 15,816,949.   If an option expires or terminates for any reason without having been fully exercised, if any shares of restricted stock are forfeited, or if any award terminates, expires or is settled without all or a portion of the shares of common stock covered by the award being issued, such shares are available for the grant of additional awards. However, any shares that are withheld (or delivered) to pay withholding taxes or to pay the exercise price of an option are not available for the grant of additional awards. As of March 31, 2022, there were options to purchase an aggregate of 10,346,223 shares of common stock outstanding.

Restricted Stock Units
The Company grants restricted stock units (RSUs) under the 2013 Plan to employees from time to time as a component of their compensation. During the three months ended March 31, 2022, the Company awarded RSUs to employees in conjunction with the annual performance review process. Each RSU vests over a two-year period and entitles the holder to receive one share of the Company's common stock when the RSU vests. Compensation expense is recognized on a straight-line basis over the vesting period.

9. Commitments and Contingencies
On September 13, 2019, a securities class action complaint was filed in the U.S. District Court for the District of Maryland (District Court) by Todd Hill naming the Company, its Chief Executive Officer, Dr. Koenig, and its Chief Financial Officer, Mr. Karrels, as defendants for allegedly making false and materially misleading statements regarding the Company’s SOPHIA trial. On August 17, 2020, the Employees’ Retirement System of the City of Baton Rouge and Parish of East Baton Rouge was appointed as Lead Plaintiff, and on October 16, 2020, the Lead Plaintiff filed an amended complaint. The amended complaint asserts a putative class period stemming from February 6, 2019 to June 4, 2019. The Company filed a Motion to Dismiss on November 30, 2020. On September 29, 2021, the District Court issued an Order dismissing the case, with prejudice. On October 28, 2021 the Lead Plaintiff filed a Notice of Appeal. The appeal is now pending in the Fourth Circuit. The Company intends to vigorously defend against this action. However, the outcome of this legal proceeding is uncertain at this time and the Company cannot reasonably estimate a range of loss, if any. Accordingly, the Company has not accrued any liability associated with this action.

ITEM 2.MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion of our financial condition and results of operations is based upon our unaudited consolidated financial statements included in this Quarterly Report on Form 10-Q, which have been prepared by us in accordance with U.S. generally accepted accounting principles (GAAP), for interim periods and with Regulation S-X promulgated under the Securities Exchange Act of 1934, as amended. This discussion and analysis should be read in conjunction with these unaudited consolidated financial statements and the notes thereto as well as in conjunction with our audited consolidated financial statements and related notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021. 

Overview
We are a biopharmaceutical company focused on developing and commercializing innovative antibody-based therapeutics for the treatment of cancer. We have a pipeline of product candidates being evaluated in clinical trials sponsored by us or our collaborators. These product candidates include multiple immuno-oncology programs, some of which were created primarily using our proprietary, antibody-based technology platforms. We believe our product candidates have the potential, if approved for marketing by regulatory authorities, to have a meaningful effect on treating patients' unmet medical needs as monotherapy or, in some cases, in combination with other therapeutic agents. In March 2021, we and our commercialization partner commenced U.S. marketing of MARGENZA (margetuximab-cmkb), a human epidermal growth factor receptor 2 (HER2) receptor antagonist indicated, in combination with chemotherapy, for the treatment of adult patients with metastatic HER2-positive breast cancer who have received two or more prior anti-HER2 regimens, at least one of which was for metastatic disease.
We commenced active operations in 2000, and have since devoted substantially all of our resources to staffing our company, developing our technology platforms, identifying potential product candidates, undertaking preclinical studies, conducting clinical trials, developing collaborations, 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, collaborations with other biopharmaceutical companies, and government grants and contracts. Although it is difficult to predict our funding requirements, we anticipate that our cash, cash equivalents and marketable securities as of March 31, 2022, combined with anticipated and potential collaboration payments and product revenues, should enable us to fund our operations through 2023. Our expected funding requirements do not reflect anticipated expenditures related to the full Phase 2/3 development of MGC018 in metastatic castration-resistant prostate cancer (mCRPC) anticipated to begin by year-end 2022, or further expansion of our other studies currently ongoing. However, we believe that we can reasonably obtain funding for the planned Phase 2 portion of the MGC018 mCRPC study through a combination of existing financial resources, a variety of external funding or potential revenue sources, and project prioritization.

Through March 31, 2022, we had an accumulated deficit of $1.0 billion. We expect that over the next several years this deficit will increase as we increase our expenditures in research and development in connection with our ongoing activities with several clinical trials, and incur costs related to commercial product sales. 
COVID-19 Pandemic

The COVID-19 pandemic has negatively impacted the global economy, created significant financial market volatility, disrupted global supply chains, and resulted in a significant number of infections and deaths worldwide. In addition, several national, state and local governments have placed restrictions on people from gathering in groups or interacting within a certain physical distance.
To date, although there has been some negative impact on our business and operations, including, for example, slowed clinical trial enrollment, we have been able to mitigate against more severe impacts of the COVID-19 pandemic on our business and operations. However, the COVID-19 pandemic could have a more significant negative impact on our business in the future depending on the depth of the effects and the duration of the crisis. In response to the COVID-19 pandemic, we have been focused on keeping our employees safe, continuing patients on trials, and maintaining our manufacturing capabilities and research efforts. The COVID-19 pandemic and its variants continue to evolve and we continue to monitor our business very closely to try and mitigate any potential impacts. We expect the pandemic to continue to have some near-term impact on the initiation of new studies and on clinical trial enrollment. Significant delays in the timing of our clinical trials and in regulatory reviews could adversely affect our ability to commercialize the product candidates in our pipeline. We are classified as a government contractor and are required to comply with Executive Order 14042. The contract terms include the requirement that all our employees that may be on site at the same location as any employee supporting the government contract be fully vaccinated against COVID-19, unless legally entitled to an accommodation due to a disability or religious belief, practice or
17



observance. In anticipation of deadlines associated with the contract terms and Executive Order 14042, we implemented a company-wide vaccination requirement by the end of 2021, with certain exceptions. To date, we do not believe our vaccination requirement has resulted in workforce attrition nor will it result in material difficulty securing future labor needs. If attrition is significant, our business could be adversely affected.
Notwithstanding the foregoing, we cannot precisely predict the impact that the COVID-19 pandemic will have in the future due to numerous uncertainties, including the severity, duration and resurgences of the disease and new variants, actions that may be taken by governmental authorities, the impact to the business of potential variations or disruptions in our supply chain, and other factors identified in Part II, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021. Given these uncertainties, the COVID-19 pandemic could disrupt the business of certain of our collaborators and impact our business operations and our ability to execute on our associated business strategies and initiatives, and adversely impact our consolidated results of operations and/or our financial condition in the future. We will continue to closely monitor and evaluate the nature and extent of the impact of the COVID-19 pandemic to our business, consolidated results of operations, and 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. In 2017, we entered into an exclusive global collaboration and license agreement with Incyte Corporation (Incyte) for retifanlimab, an investigational monoclonal antibody that inhibits programmed cell death protein 1 (PD-1) (Incyte License Agreement). 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. Incyte paid us an upfront payment of $150.0 million under the terms of the agreement. In July 2021, Incyte announced that the U.S. Food and Drug Administration (FDA) had issued a Complete Response Letter (CRL) regarding its Biologics License Application (BLA) for retifanlimab as a potential treatment for adult patients with locally advanced or metastatic squamous cell carcinoma of the anal canal. Incyte’s announcement indicated that the FDA determined that additional data were needed to demonstrate the clinical benefit of retifanlimab for the submitted indication, and that Incyte was reviewing the CRL and would discuss next steps with the FDA. Incyte subsequently withdrew its European application for marketing authorization of retifanlimab for the treatment of squamous carcinoma of the anal canal. Incyte has stated it is pursuing development of retifanlimab in potentially registration-enabling studies beyond squamous cell carcinoma of the anal canal, including in patients with MSI-high endometrial cancer, Merkel cell carcinoma and non-small cell lung cancer. Incyte is also pursuing development of retifanlimab in combination with multiple product candidates from its pipeline.

Under the terms of the Incyte License Agreement, Incyte leads global development of retifanlimab. Assuming successful development and commercialization of retifanlimab by Incyte, we could receive total development and regulatory milestones of up to approximately $420.0 million and up to $330.0 million in commercial milestones. We received $70.0 million of the total development milestones through March 31, 2022. If retifanlimab is approved and commercialized, we would be eligible to receive tiered royalties of 15% to 24% on any global net sales 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 to perform development and manufacturing services for Incyte's clinical needs of retifanlimab (Incyte Clinical Supply Agreement) and another agreement under which we are entitled to manufacture a portion of Incyte’s global commercial supply of retifanlimab (Incyte Commercial Supply Agreement).
Zai Lab. In 2018, we entered into a collaboration and license agreement with Zai Lab Limited (Zai Lab) under which Zai Lab obtained regional development and commercialization rights in mainland China, Hong Kong, Macau and Taiwan (Zai Lab’s territory) for (i) margetuximab, an immune-optimized anti-HER2 monoclonal antibody, (ii) tebotelimab, a bispecific DART molecule designed to provide coordinate blockade of PD-1 and LAG-3 for the potential treatment of a range of solid tumors and hematological malignancies, and (iii) an undisclosed multi-specific TRIDENT molecule in preclinical development (2018 Zai Lab Agreement). Zai Lab will lead clinical development in its territory.

Under the terms of the 2018 Zai Lab Agreement, Zai Lab paid us an upfront payment of $25.0 million less foreign withholding tax of $2.5 million. Assuming successful development and commercialization of margetuximab, tebotelimab and the TRIDENT molecule, we could receive up to $140.0 million in development and regulatory milestones, of which we have already earned $9.0 million. In addition, Zai Lab would pay us tiered royalties at percentage rates of mid-teens to 20% for net sales of margetuximab in Zai Lab’s territory, mid-teens for net sales of tebotelimab in Zai Lab’s territory and 10% for net sales of the TRIDENT molecule in Zai Lab’s territory, which may be subject to adjustment in specified circumstances.
In 2019, we entered into two agreements under which we are to perform manufacturing services for Zai Lab’s clinical needs of margetuximab and tebotelimab (Zai Lab Clinical Supply Agreements).
In June 2021, we entered into a collaboration and license agreement with Zai Lab US LLC (collectively with Zai Lab Limited referred herein as Zai Lab) involving collaboration programs and license-only programs (collectively, the Programs) encompassing four separate immuno-oncology molecules (2021 Zai Lab Agreement). The first program covers a lead research molecule that incorporates our DART platform and binds CD3 and an undisclosed target that is expressed in multiple solid tumors (Lead Program). The second program covers a target to be designated by us. For these programs, Zai Lab receives commercial rights in Greater China, Japan, and Korea while we receive commercial rights in all other territories. Under the Lead Program, Zai Lab received an option upon reaching a predefined clinical milestone to convert the regional arrangement into a global 50/50 profit share. If Zai Lab elects such option, Zai Lab is to pay us $85.0 million plus any research costs incurred by both parties as of the option election date. Zai Lab also obtained exclusive, global licenses from us to develop, manufacture and commercialize two additional molecules (license-only programs). Zai Lab granted us a worldwide, royalty-free, co-exclusive license to conduct the development activities allocated to us.

Under the terms of the 2021 Zai Lab Agreement, the Lead Program includes joint research and development services by both us and Zai Lab. For the other programs, Zai Lab can separately negotiate and agree with us to perform research and development services in the future.
In connection with the execution of the 2021 Zai Lab Agreement, Zai Lab paid us an upfront payment of $25.0 million. Additionally, as part of the consideration for the rights granted to Zai Lab under the 2021 Zai Lab Agreement, we and Zai Lab entered into a separate stock purchase agreement (Stock Purchase Agreement) whereby Zai Lab paid us approximately $30.0 million to purchase 958,467 newly issued shares of our common stock, par value $0.01, at a fixed price of $31.30 which represented a $10.4 million premium over the share price on the Stock Purchase Agreement date.
Assuming successful development and commercialization of the Programs under the 2021 Zai Lab Agreement, we could receive up to $1.4 billion in development, regulatory and commercial milestones. In addition, Zai Lab would pay us tiered royalties at percentage rates of low double digit teens on annual net sales of certain specified products and of mid-single digits to low double digit teens on annual net sales of other specified products in Zai's territory, subject to specified royalty reduction pursuant to the 2021 Zai Lab Agreement. Per the terms of the 2021 Zai Lab Agreement, we may also receive reimbursements from Zai Lab for certain research and development costs incurred by us.
I-Mab Biopharma. In 2019, we entered into a collaboration and license agreement with I-Mab Biopharma (I-Mab) to develop and commercialize enoblituzumab, an immune-optimized, anti-B7-H3 monoclonal antibody that incorporates our proprietary Fc Optimization technology platform (I-Mab License Agreement). I-Mab obtained regional development and commercialization rights in mainland China, Hong Kong, Macau and Taiwan (I-Mab's territory), will lead clinical development of enoblituzumab in its territories, and will participate in global studies conducted by us.

Under the terms of the agreement, I-Mab paid us an upfront payment of $15.0 million. Assuming successful development and commercialization of enoblituzumab, we could receive up to $135.0 million in development and regulatory milestones of which $5.0 million has been earned from the inception of the I-Mab License Agreement through
March 31, 2022. In addition, I-Mab would pay us tiered royalties ranging from mid-teens to 20% on annual net sales in its territories.
In October 2021, we entered into an agreement under which we are to perform development and manufacturing services for I-Mab’s clinical needs of enoblituzumab.
19



Janssen. In December 2020, we entered into a research collaboration and global license agreement to develop a preclinical bispecific molecule with Janssen Biotech, Inc. (Janssen). The research collaboration will incorporate our proprietary DART platform to enable simultaneous targeting of two undisclosed targets in a therapeutic area outside oncology. Under the terms of the agreement, Janssen paid us an upfront payment of $20.0 million and will be responsible for funding all expenses. We will also be eligible to receive up to $312.0 million in potential milestone payments and tiered royalties of up to 10% on worldwide product sales.

Critical Accounting Estimates
Our critical accounting estimates are policies which require the most significant judgments and estimates in the preparation of our consolidated financial statements. A summary of our critical accounting estimates is presented in Part II, Item 7, of our Annual Report on Form 10-K for the year ended December 31, 2021. There have been no material changes with respect to our critical accounting estimates during the three months ended March 31, 2022.

Results of Operations
Revenue
The following represents a comparison of our revenue for the three months ended March 31, 2022 and 2021 (dollars in millions):
Three Months Ended March 31,Increase/(Decrease)
20222021
Revenue from collaborative and other agreements$7.1 $15.2 $(8.1)(53)%
Product revenue, net3.6 0.9 2.7 300 %
Revenue from government agreements0.4 0.8 (0.4)(47)%
Total revenue$11.1 $16.9 $(5.8)(34)%

The decrease in revenue of $5.8 million for the three months ended March 31, 2022 compared to the three months ended March 31, 2021 was primarily due to:
a decrease of $10.0 million in development milestones recognized under the Incyte License Agreement; and
a decrease of $3.0 million in revenue recognized under the Incyte Commercial Supply Agreement due to timing of manufacturing activities.
These decreases were partially offset by:
recognition of a $5.0 million milestone under the 2018 Zai Lab Agreement during the three months ended March 31, 2022; and
an increase of $2.7 million in net product revenue from sales of MARGENZA.
Cost of Product Sales
Cost of product sales for the three months ended March 31, 2022 and 2021 consisted primarily of product royalties and fill finish costs. Product sold during these periods consisted of drug product that was previously charged to research and development expense prior to FDA approval of MARGENZA, which favorably impacted our gross margin for the three months ended March 31, 2022 and 2021. We expect cost of product sales to continue to be positively impacted as we sell through this drug product.
Research and Development Expense
The following represents a comparison of our research and development expense for the three months ended March 31, 2022 and 2021 (dollars in millions):
20



Three Months Ended March 31,Increase/(Decrease)
20222021
MGC018$16.5 $4.7 $11.8 251 %
Margetuximab8.2 12.2 (4.0)(33)%
Flotetuzumab5.1 9.4 (4.3)(46)%
Lorigerlimab5.0 3.1 1.9 61 %
Enoblituzumab4.9 4.1 0.8 20 %

IMGC9362.4 0.9 1.5 167 %
Retifanlimab1.5 3.9 (2.4)(62)%
MGD0241.3 0.9 0.4 44 %
DART molecules under HIV government contract0.9 1.5 (0.6)(40)%
Other programs (a)11.4 7.1 4.3 61 %
Total research and development expense$61.4 $53.1 $8.3 16 %
(a) Includes research and discovery projects, as well as early preclinical and terminated molecules.
Our research and development expense for the three months ended March 31, 2022 increased by $8.3 million compared to the three months ended March 31, 2021 primarily due to:
increased development, manufacturing and clinical trial costs related to MGC018;
increased development of discovery projects and preclinical molecules; and
increased clinical trial enrollment costs related to lorigerlimab.
These increases were partially offset by:
decreased development, manufacturing and clinical trial costs related to flotetuzumab, which development has been discontinued;
decreased margetuximab manufacturing costs related to the Zai Lab Clinical Supply Agreement; and
decreased retifanlimab manufacturing costs related to the Incyte Commercial Supply Agreement.
We expect our research and development expense will continue to increase as we progress our pipeline of product candidates.
Selling, General and Administrative Expense
Selling, general and administrative expenses increased by $1.2 million for the three months ended March 31, 2022 compared to the three months ended March 31, 2021 primarily due to MARGENZA selling costs, as well as increased stock-based compensation and consulting expenses.

Liquidity and Capital Resources
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. As a biotechnology company, we have primarily funded our operations with proceeds from the sale of our common stock in equity offerings, revenue from our multiple collaboration agreements, and contracts and grants from the National Institute of Allergy and Infectious Diseases. 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
21



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 March 31, 2022, as well as anticipated and potential collaboration payments, and product revenues should enable us to fund our operations through 2023. Our expected funding requirements do not reflect anticipated expenditures related to the full Phase 2/3 development of MGC018 in mCRPC anticipated to begin by year-end 2022, or further expansion of our other studies currently ongoing. However, we believe that we can reasonably obtain funding for the planned Phase 2 portion of the MGC018 mCRPC study through a combination of existing financial resources, a variety of external funding or potential revenue sources, and project prioritization.
Material Cash Requirements
During the three months ended March 31, 2022, there were no significant changes to our material cash requirements, including contractual and other obligations, as presented in Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021.
Cash Flows
The following table represents a summary of our cash flows for the three months ended March 31, 2022 and 2021:
