Collaboration and License Agreements [Abstract]
Revenue	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, which was amended in March 2018, April 2022, July 2022 and July 2024, for retifanlimab, an investigational monoclonal antibody that inhibits 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. The Company manufactured a portion of Incyte’s global commercial supply of retifanlimab until June 30, 2026 when it sold its CDMO Operations to Bora; see Note 11, Discontinued Operations, for additional information. In March 2023, the FDA approved Incyte's Biologics License Application (BLA) for ZYNYZ (retifanlimab-dlwr) for the treatment of adults with metastatic or recurrent locally advanced Merkel cell carcinoma. In May 2025, the FDA approved ZYNYZ with carboplatin and paclitaxel for the first-line treatment of adults with inoperable locally recurrent or metastatic squamous cell carcinoma of the anal canal (SCAC), and as a single agent, for adults with locally recurrent or metastatic SCAC with disease progression on or intolerance to platinum-based chemotherapy. In December 2025, Japan's Ministry of Health, Labour and Welfare approved ZYNYZ as first-line therapy for adults with locally recurrent or metastatic SCAC. In March 2026, Incyte announced that the European Commission approved ZYNYZ in combination with carboplatin and paclitaxel for the first-line treatment of adult patients with metastatic or inoperable locally recurrent SCAC. Furthermore, Incyte has stated it is pursuing development of retifanlimab in potentially registration-enabling studies, including in patients with non-small cell lung cancer. Incyte is also pursuing development of retifanlimab in combination with select product candidates from its pipeline. Under the terms of the Incyte License Agreement, as amended, Incyte leads global development of retifanlimab. From the inception of the Incyte License Agreement through June 30, 2026, the Company has recognized $215.0 million for certain development and regulatory milestones under the Incyte License Agreement. Assuming successful development and commercialization by Incyte in multiple indications, the Company is eligible to receive up to an additional $210.0 million in development and regulatory milestones and up to $330.0 million in commercial milestones. The Company was also eligible to receive tiered royalties of 15% to 24% on global net sales, but sold this right to Sagard in June 2025 as described more fully in Note 5. Royalty Monetization Arrangement. 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. The Company evaluated the Incyte License Agreement under the provisions of ASC Topic 606, Revenue from Contracts with Customers (ASC 606) at inception 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. In July 2024, the Company and Incyte executed Amendment No. 4 to the Incyte License Agreement pursuant to which certain development milestones were deemed to have been met. The Company evaluated the amendment as a contract modification under the provisions of ASC 606 which resulted in $100.0 million of revenue being recognized in 2024. From 2018 through June 30, 2026, it became probable that a significant reversal of cumulative revenue would not occur for development milestones totaling $215.0 million related to clinical and regulatory activities related to the further advancement of retifanlimab. 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. The Company recognized $7.3 million and $1.3 million in royalty revenue under the Incyte License Agreement during the three months ended June 30, 2026 and 2025 respectively. The Company recognized $13.5 million and $1.8 million in royalty revenue under the Incyte License Agreement during the six months ended June 30, 2026 and 2025, respectively. Incyte Commercial Supply Agreement In 2020, the Company entered into an agreement with Incyte pursuant to which the Company was 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 this 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 was based on a fixed price per batch of bulk drug substance to be manufactured and was recognized over time as the services were provided, as the performance by the Company did not create an asset with an alternative use and the Company had an enforceable right to payment for the performance completed to date. The transaction price was being recognized using the input method reflecting the costs incurred (including resources consumed and labor costs incurred) related to the manufacturing services. Variable consideration relating to the reimbursed materials and other reimbursed costs incurred to manufacture retifanlimab was allocated to the related manufacturing activities and was recognized as revenue as those activities occurred. Materials purchased by the Company to manufacture retifanlimab were considered inventory and were capitalized and expensed as the materials were used to provide the manufacturing services. As part of the sale of the Company's CDMO Operations, (see Note 11), the Incyte Commercial Supply Agreement was assigned to Bora. The Company recognized $10.3 million in revenue during the three months ended June 30, 2026, and recognized no revenue during the three months ended June 30, 2025 under the Incyte Commercial Supply Agreement, which is reflected in the Net income from discontinued operations, net of taxes line on the consolidated statements of operations and comprehensive income (loss). The Company recognized $14.4 million and $0.4 million in revenue under the Incyte Commercial Supply Agreement during the six months ended June 30, 2026 and 2025, respectively, which is reflected in the Net income from discontinued operations, net of taxes line on the consolidated statements of operations and comprehensive income (loss). Gilead Sciences, Inc In 2022, the Company and Gilead Sciences, Inc. (Gilead) entered into an exclusive option and collaboration agreement (Gilead Agreement) to develop and commercialize MGD024, an investigational, bispecific antibody that binds CD123 and CD3, and create bispecific cancer antibodies using the Company’s DART and TRIDENT platforms and undertake their early development under a maximum of two separate bispecific cancer target research programs. Under the agreement, the Company will continue 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 under the Company’s intellectual property to develop and commercialize MGD024 and other bispecific antibodies of MacroGenics 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 the Company 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). Gilead nominated the first of the two research programs in September 2023. 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. On August 30, 2024, the parties amended the agreement by entering into a second letter agreement under which Gilead will pay the Company to conduct certain research and which extended the period for Gilead to select its second research target combination. Under the terms of the Gilead Agreement, as amended, in October 2022 Gilead paid the Company an upfront payment of $60.0 million. Assuming Gilead exercises the CD123 Option and Research Program Option and successfully develops and commercializes MGD024, or other CD123 products developed under the agreement, and products result from the two additional research programs, the Company would be eligible to receive up to a total of $1.7 billion in target nomination, option fees, and development, regulatory and commercial milestones. Assuming exercise of the CD123 Option, the Company 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. The Company evaluated the Gilead Agreement under the provisions of ASC 606 and identified the following material promises under the agreement: (i) a license to perform any activities allocated to Gilead under the MGD024 development plan; (ii) development activities regarding MGD024, including manufacturing, research and early clinical development activities, necessary to deliver an informational package of development and clinical data, information and materials specified in the Gilead Agreement during the period in which Gilead can exercise the CD123 Option; (iii) the CD123 Option and (iv) the Research Program Option. The Company concluded that the license under the MGD024 development plan and development activities are not distinct from one another, as the license has limited value without the Company’s performance of the development activities. Therefore, the Company determined that the development term license and development activities should be combined into a single performance obligation (Development Activities). The CD123 Option is considered a material right as the value of the exclusive license exceeds the payment to be made by Gilead if they exercise their option to obtain an exclusive license to develop and commercialize MGD024 or an alternative CD123 product, and is therefore a distinct performance obligation. The Company determined that the Research Program Option does not provide a material right, as there is no discount on its standalone selling price. In accordance with ASC 606, the Company determined that the initial transaction price under the Gilead Agreement was $60.0 million, consisting of the upfront, non-refundable payment paid by Gilead. The CD123 Option and Research Program Option payments are excluded from the initial transaction price at contract inception along with any future development, regulatory, and commercial milestone payments (including royalties) following the CD123 Option and Research Program Option exercise. The Company reassesses the amount of variable consideration included in the transaction price every reporting period. The Company allocated the $60.0 million upfront payment in the transaction price to the Development Activities and the CD123 Option based on each performance obligation’s relative standalone selling price. The standalone selling price for the Development Activities was calculated using an expected cost-plus margin approach for the pre-option development timeline. For the standalone selling price of the CD123 Option, the Company utilized an income-based approach which included the following key assumptions: post-option development timeline and costs, forecasted revenues, discount rates and probabilities of technical and regulatory success. The Company is recognizing revenue related to the Development Activities performance obligation over the estimated period to complete the Development Activities using an input method reflecting the costs incurred (including resources consumed and labor hours expended) related to the Development Activities. The Company has deferred revenue recognition related to the CD123 Option. If Gilead exercises the CD123 Option and obtains an exclusive license, the Company will recognize revenue as it fulfills its obligations under the Gilead Agreement. If the CD123 Option is not exercised, the Company will recognize the entirety of the revenue in the period when the CD123 Option expires. The Company recognized $1.0 million and $0.5 million in revenue under the Gilead Agreement during the three months ended June 30, 2026 and 2025, respectively. During the six months ended June 30, 2026 and 2025, the Company recognized revenue of $1.3 million and $0.1 million, respectively. As of June 30, 2026, $55.5 million in revenue was deferred under this agreement, all of which was current. As of December 31, 2025, $56.8 million in revenue was deferred under this agreement, $1.3 million of which was current and $55.5 million of which was non-current. In September 2023, the Company and Gilead executed a letter agreement (First Letter Agreement) through which Gilead nominated the first of the two research programs contemplated in the Gilead Agreement (First Research Program), the Company granted Gilead a research license, and the parties agreed on a research plan for the First Research Program under which the Company will provide research and development services. Gilead paid the Company a $15.7 million nomination fee. The Company evaluated the First Letter Agreement under the terms of ASC 606, and concluded that it is a modification to the Gilead Agreement that results in a separate contract since the modification is for additional goods and services that are distinct and at standalone selling price. 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 these should be combined into a single performance obligation. Gilead also has the exclusive option to pay the Company $10.0 million to obtain a license to exploit the research molecule and research product with respect to the First Research Program. The Company determined that this exclusive option does not provide a material right, as there is no discount on its standalone selling price. In accordance with ASC 606, the Company determined that the initial transaction price for the First Research Program agreement was $15.7 million, consisting of the non-refundable payment paid by Gilead. The Company recognized revenue over the estimated period to complete the services using the input method reflecting the costs incurred (including resources consumed and labor hours expended) related to the research and development services. In June 2024, the Company received variable consideration totaling $3.3 million from Gilead upon achievement of a research plan milestone. The variable consideration was added to the transaction price and allocated to the performance obligation to determine the amount of related revenue to be recognized. A proportional amount was recognized based on the input cost to cost measurement of work completed to date. The Company completed performing the services and recognizing revenue related to the First Research Program in mid-2025. The Company recorded $5.6 million and $11.0 million in revenue related to the First Research Program during the three and six months ended June 30, 2025, respectively. In November 2025, the parties amended the Gilead Agreement by entering into a third letter agreement (Third Letter Agreement) under which Gilead nominated the second of the two research programs contemplated in the Gilead Agreement (Second Research Program) and the Company 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 the Company a total of $25.0 million related to the nomination and option exercise. The Company evaluated the Third Letter Agreement under the terms of ASC 606, and concluded that it is a modification to the Gilead Agreement that results in a separate contract since the modification is for additional goods and services that are distinct and at standalone selling price. The Company determined that there is one performance obligation under the Third Letter Agreement; to grant the research term license and exploitation license. In accordance with ASC 606, the Company determined that the initial transaction price for the Second Research Program was $25.0 million, consisting of the non-refundable payment made by Gilead. The Company recognized this amount when it satisfied its performance obligation and transferred the license to Gilead during the year ended December 31, 2025. The Company is entitled to future development, regulatory and commercial milestones related to the Second Research Program should Gilead successfully develop and commercialize the molecule. These 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 Gilead and, therefore, have also been excluded from the transaction price. Sanofi S.A. In 2018, the Company entered into an asset purchase agreement with Provention Bio, Inc. (Provention) pursuant to which Provention acquired the Company’s interest in teplizumab, a monoclonal antibody being developed for the treatment of type 1 diabetes (Provention APA). The FDA approved the BLA for TZIELD (teplizumab-mzwv) in November 2022. In March 2023, the Company sold its single-digit royalty interest in TZIELD to a wholly-owned subsidiary of DRI Healthcare Trust (DRI) and received a $100.0 million payment from DRI under a Royalty Purchase Agreement. The Company retained its other economic interests related to TZIELD, including future potential regulatory and commercial milestones, as well as the right to receive a 50% share of the royalty on global net sales above a certain annual threshold. In addition, the Company was eligible to receive an additional $50.0 million if TZIELD achieved a certain level of net sales by June 30, 2026. This milestone was not achieved and has expired. In April 2023, Sanofi S.A. (Sanofi) completed its acquisition of Provention and the Company entered into a tripartite agreement with DRI and Sanofi under which it was released of any obligations under the Royalty Purchase Agreement. In September 2023, the Company and Sanofi executed Amendment No. 2 to the Provention APA and terminated the Royalty Purchase Agreement with DRI. As a result, the remaining $50.0 million sales milestone under the Royalty Purchase Agreement was incorporated into the Provention APA. The Company evaluated the Provention APA under the provisions of ASC 606, and determined that 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. Any consideration related to sales-based milestones will be recognized when the related sales occur. The Company re-assesses the transaction price in each reporting period and when events whose outcomes are resolved or other changes in circumstances occur. During the three months ended June 30, 2026, a regulatory milestone was achieved and the Company recognized $24.5 million in revenue. Payment for this milestone is not due from Sanofi until September 2026, therefore the $24.5 million is included in accounts receivable on the consolidated balance sheet. As of June 30, 2026, the remaining future potential regulatory and commercial milestones total $255.0 million. Manufacturing Services Agreements Incyte In January 2022, the Company entered into a Manufacturing and Clinical Supply Agreement with Incyte (2022 Incyte Manufacturing and Clinical Supply Agreement) to provide manufacturing services to produce certain Incyte bulk drug substance over a three-year period. Under the terms of the 2022 Incyte Manufacturing and Clinical Supply Agreement, the Company received an upfront payment of $10.0 million and was eligible to receive annual fixed payments paid quarterly over the term of the contract totaling $14.4 million. The Company was also reimbursed for materials used to manufacture product as well as other costs incurred to provide manufacturing services. In July 2022, the Company and Incyte executed an amendment to the 2022 Incyte Manufacturing and Clinical Supply Agreement which extended the term for one year and provided for an additional annual fixed payment of $5.1 million (July 2022 Incyte Amendment). In December 2024 and March 2025, the Company and Incyte entered into letter agreements whereby Incyte reserved additional manufacturing services during 2025 with a total fixed cost of $13.5 million (Incyte Letter Agreements). The Company evaluated the 2022 Incyte Manufacturing and Clinical Supply Agreement, the July 2022 Incyte Amendment and the Incyte Letter Agreements 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 consists of the upfront payment of $10.0 million, the annual fixed payments and the payments per batch under the Incyte Letter Agreements totaling $41.7 million. The Company recognized revenue over time on a straight-line basis as the manufacturing services were provided to Incyte, as the Company determined that its efforts in providing the manufacturing services were incurred evenly throughout the performance period and therefore straight-line revenue recognition closely approximated 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 was allocated to the related manufacturing activities and was recognized as revenue as those activities occurred. Materials purchased by the Company to manufacture the product for Incyte were considered inventory and were capitalized and expensed as the materials were used to provide the manufacturing services. The 2022 Incyte Manufacturing and Clinical Supply Agreement expired on December 31, 2025. During the three and six months ended June 30, 2025, the Company recognized revenue of $13.3 million and $18.3 million, respectively, under the 2022 Incyte Manufacturing and Clinical Supply Agreement. In September 2025, the Company entered into a new Manufacturing and Clinical Supply Agreement with Incyte (2025 Incyte Manufacturing and Clinical Supply Agreement) to provide manufacturing services to produce certain Incyte bulk drug substance over a three-year period beginning in January 2026. Based on the current manufacturing schedule contemplated in the 2025 Incyte Manufacturing and Clinical Supply Agreement, Incyte was to pay a total fixed cost of $16.8 million over the term of the agreement. The Company would also be reimbursed for materials used to manufacture product as well as other costs incurred to provide manufacturing services. The Company evaluated the 2025 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 recognized revenue over time on a straight-line basis as the manufacturing services were provided to Incyte, as the Company determined that its efforts in providing the manufacturing services were incurred evenly throughout the performance period and therefore straight-line revenue recognition closely approximated 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 was allocated to the related manufacturing activities and was recognized as revenue as those activities occurred. Materials purchased by the Company to manufacture the product for Incyte were considered inventory and were capitalized and expensed as the materials were used to provide the manufacturing services. As described more fully in Note 11, Discontinued Operations, the Company sold its CDMO Operations as of June 30, 2026 and assigned the 2025 Incyte Manufacturing and Clinical Supply Agreement to Bora. During the three and six months ended June 30, 2026, the Company recognized revenue of $0.8 million and $4.7 million, respectively, under the 2025 Incyte Manufacturing and Clinical Supply Agreement, which is reflected in the Net income from discontinued operations, net of taxes line on the consolidated statements of operations and comprehensive income (loss). Emergent BioSolutions In 2024 and 2025, the Company entered into agreements with Emergent BioSolutions (Emergent) to provide manufacturing services to produce certain Emergent bulk drug substance (Emergent Agreement). Under the terms of the agreement, the Company received payments in accordance with the manufacturing schedule and was reimbursed for materials used to manufacture product, as well as other costs incurred to provide development and manufacturing services. The Company evaluated the Emergent Agreement under the provisions of ASC 606 and identified one performance obligation to manufacture bulk drug substances over the term of the contract that is part of a series of goods and services. The Company determined that the transaction price consisted of $13.5 million of fixed consideration. The Company recognized revenue over time on a straight-line basis as the manufacturing is provided to Emergent, as the Company determined that its efforts in providing the manufacturing services were incurred evenly throughout the performance period and therefore straight-line revenue recognition closely approximated the level of effort for the manufacturing services. Variable consideration relating to the reimbursed materials and other reimbursed costs incurred to manufacture product for Emergent was allocated to the related manufacturing activities and was recognized as revenue as those activities occurred. The Emergent Agreement was assigned to Bora as of June 30, 2026. During the three months ended June 30, 2026 and 2025, the Company recognized revenue of $1.9 million and $1.6 million, respectively, under the Emergent Agreement. During the six months ended June 30, 2026 and 2025 the Company recognized revenue of $7.5 million and $2.8 million, respectively, under the Emergent Agreement, which is reflected in the Net income from discontinued operations, net of taxes line on the consolidated statements of operations and comprehensive income (loss).

In 2017, the Company entered into an exclusive global collaboration and license agreement with Incyte, which was amended in March 2018, April 2022, July 2022 and July 2024, for retifanlimab, an investigational monoclonal antibody that inhibits 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. The Company manufactured a portion of Incyte’s global commercial supply of retifanlimab until June 30, 2026 when it sold its CDMO Operations to Bora; see Note 11, Discontinued Operations, for additional information. In March 2023, the FDA approved Incyte's Biologics License Application (BLA) for ZYNYZ (retifanlimab-dlwr) for the treatment of adults with metastatic or recurrent locally advanced Merkel cell carcinoma. In May 2025, the FDA approved ZYNYZ with carboplatin and paclitaxel for the first-line treatment of adults with inoperable locally recurrent or metastatic squamous cell carcinoma of the anal canal (SCAC), and as a single agent, for adults with locally recurrent or metastatic SCAC with disease progression on or intolerance to platinum-based chemotherapy. In December 2025, Japan's Ministry of Health, Labour and Welfare approved ZYNYZ as first-line therapy for adults with locally recurrent or metastatic SCAC. In March 2026, Incyte announced that the European Commission approved ZYNYZ in combination with carboplatin and paclitaxel for the first-line treatment of adult patients with metastatic or inoperable locally recurrent SCAC. Furthermore, Incyte has stated it is pursuing development of retifanlimab in potentially registration-enabling studies, including in patients with non-small cell lung cancer. Incyte is also pursuing development of retifanlimab in combination with select product candidates from its pipeline.

Under the terms of the Incyte License Agreement, as amended, Incyte leads global development of retifanlimab. From the inception of the Incyte License Agreement through June 30, 2026, the Company has recognized $215.0 million for certain development and regulatory milestones under the Incyte License Agreement. Assuming successful development and commercialization by Incyte in multiple indications, the Company is eligible to receive up to an additional $210.0 million in development and regulatory milestones and up to $330.0 million in commercial milestones. The Company was also eligible to receive tiered royalties of 15% to 24% on global net sales, but sold this right to Sagard in June 2025 as described more fully in Note 5. Royalty Monetization Arrangement. 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.

The Company evaluated the Incyte License Agreement under the provisions of ASC Topic 606, Revenue from Contracts with Customers (ASC 606) at inception 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. In July 2024, the Company and Incyte executed Amendment No. 4 to the Incyte License Agreement pursuant to which certain development milestones were deemed to have been met. The Company evaluated the amendment as a contract modification under the provisions of ASC 606 which resulted in $100.0 million of revenue being recognized in 2024. From 2018 through June 30, 2026, it became probable that a significant reversal of cumulative revenue would not occur for development milestones totaling $215.0 million related to clinical and regulatory activities related to the further advancement of retifanlimab. 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. The Company recognized $7.3 million and $1.3 million in royalty revenue under the Incyte License Agreement during the three months ended June 30, 2026 and 2025 respectively. The Company recognized $13.5 million and $1.8 million in royalty revenue under the Incyte License Agreement during the six months ended June 30, 2026 and 2025, respectively.

In 2020, the Company entered into an agreement with Incyte pursuant to which the Company was 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 this 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 was based on a fixed price per batch of bulk drug substance to be manufactured and was recognized over time as the services were provided, as the performance by the Company did not create an asset with an alternative use and the Company had an enforceable right to payment for the performance completed to date. The transaction price was being recognized using the input method reflecting the costs incurred (including resources consumed and labor costs incurred) related to the manufacturing services. Variable consideration relating to the reimbursed materials and other reimbursed costs incurred to manufacture retifanlimab was allocated to the related manufacturing activities and was recognized as revenue as those activities occurred. Materials purchased by the Company to manufacture retifanlimab were considered inventory and were capitalized and expensed as the materials were used to provide the manufacturing services. As part of the sale of the Company's CDMO Operations, (see Note 11), the Incyte Commercial Supply Agreement was assigned to Bora. The Company recognized $10.3 million in revenue during the three months ended June 30, 2026, and recognized no revenue during the three months ended June 30, 2025 under the Incyte Commercial Supply Agreement, which is reflected in the Net income from discontinued operations, net of taxes line on the consolidated statements of operations and comprehensive income (loss). The Company recognized $14.4 million and $0.4 million in revenue under the Incyte Commercial Supply Agreement during the six months ended June 30, 2026 and 2025, respectively, which is reflected in the Net income from discontinued operations, net of taxes line on the consolidated statements of operations and comprehensive income (loss).

In 2022, the Company and Gilead Sciences, Inc. (Gilead) entered into an exclusive option and collaboration agreement (Gilead Agreement) to develop and commercialize MGD024, an investigational, bispecific antibody that binds CD123 and CD3, and create bispecific cancer antibodies using the Company’s DART and TRIDENT platforms and undertake their early development under a maximum of two separate bispecific cancer target research programs. Under the agreement, the Company will continue 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 under the Company’s intellectual property to develop and

commercialize MGD024 and other bispecific antibodies of MacroGenics 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 the Company 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). Gilead nominated the first of the two research programs in September 2023. 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. On August 30, 2024, the parties amended the agreement by entering into a second letter agreement under which Gilead will pay the Company to conduct certain research and which extended the period for Gilead to select its second research target combination.

Under the terms of the Gilead Agreement, as amended, in October 2022 Gilead paid the Company an upfront payment of $60.0 million. Assuming Gilead exercises the CD123 Option and Research Program Option and successfully develops and commercializes MGD024, or other CD123 products developed under the agreement, and products result from the two additional research programs, the Company would be eligible to receive up to a total of $1.7 billion in target nomination, option fees, and development, regulatory and commercial milestones. Assuming exercise of the CD123 Option, the Company 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.

The Company evaluated the Gilead Agreement under the provisions of ASC 606 and identified the following material promises under the agreement: (i) a license to perform any activities allocated to Gilead under the MGD024 development plan; (ii) development activities regarding MGD024, including manufacturing, research and early clinical development activities, necessary to deliver an informational package of development and clinical data, information and materials specified in the Gilead Agreement during the period in which Gilead can exercise the CD123 Option; (iii) the CD123 Option and (iv) the Research Program Option.

The Company concluded that the license under the MGD024 development plan and development activities are not distinct from one another, as the license has limited value without the Company’s performance of the development activities. Therefore, the Company determined that the development term license and development activities should be combined into a single performance obligation (Development Activities). The CD123 Option is considered a material right as the value of the exclusive license exceeds the payment to be made by Gilead if they exercise their option to obtain an exclusive license to develop and commercialize MGD024 or an alternative CD123 product, and is therefore a distinct performance obligation. The Company determined that the Research Program Option does not provide a material right, as there is no discount on its standalone selling price.

In accordance with ASC 606, the Company determined that the initial transaction price under the Gilead Agreement was $60.0 million, consisting of the upfront, non-refundable payment paid by Gilead. The CD123 Option and Research Program Option payments are excluded from the initial transaction price at contract inception along with any future development, regulatory, and commercial milestone payments (including royalties) following the CD123 Option and Research Program Option exercise. The Company reassesses the amount of variable consideration included in the transaction price every reporting period. The Company allocated the $60.0 million upfront payment in the transaction price to the Development Activities and the CD123 Option based on each performance obligation’s relative standalone selling price. The standalone selling price for the Development Activities was calculated using an expected cost-plus margin approach for the pre-option development timeline. For the standalone selling price of the CD123 Option, the Company utilized an income-based approach which included the following key assumptions: post-option development timeline and costs, forecasted revenues, discount rates and probabilities of technical and regulatory success.

The Company is recognizing revenue related to the Development Activities performance obligation over the estimated period to complete the Development Activities using an input method reflecting the costs incurred (including resources consumed and labor hours expended) related to the Development Activities. The Company has deferred revenue recognition related to the CD123 Option. If Gilead exercises the CD123 Option and obtains an exclusive license, the Company will recognize revenue as it fulfills its obligations under the Gilead Agreement. If the CD123 Option is not exercised, the Company will recognize the entirety of the revenue in the period when the CD123 Option expires.

The Company recognized $1.0 million and $0.5 million in revenue under the Gilead Agreement during the three months ended June 30, 2026 and 2025, respectively. During the six months ended June 30, 2026 and 2025, the Company recognized revenue of $1.3 million and $0.1 million, respectively. As of June 30, 2026, $55.5 million in revenue was deferred under this agreement, all of which was current. As of December 31, 2025, $56.8 million in revenue was deferred under this agreement, $1.3 million of which was current and $55.5 million of which was non-current.

In September 2023, the Company and Gilead executed a letter agreement (First Letter Agreement) through which Gilead nominated the first of the two research programs contemplated in the Gilead Agreement (First Research Program), the Company granted Gilead a research license, and the parties agreed on a research plan for the First Research Program under which the Company will provide research and development services. Gilead paid the Company a $15.7 million nomination fee. The Company evaluated the First Letter Agreement under the terms of ASC 606, and concluded that it is a modification to the Gilead Agreement that results in a separate contract since the modification is for additional goods and services that are distinct and at standalone selling price. 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 these should be combined into a single performance obligation. Gilead also has the exclusive option to pay the Company $10.0 million to obtain a license to exploit the research molecule and research product with respect to the First Research Program. The Company determined that this exclusive option does not provide a material right, as there is no discount on its standalone selling price.

In accordance with ASC 606, the Company determined that the initial transaction price for the First Research Program agreement was $15.7 million, consisting of the non-refundable payment paid by Gilead. The Company recognized revenue over the estimated period to complete the services using the input method reflecting the costs incurred (including resources consumed and labor hours expended) related to the research and development services. In June 2024, the Company received variable consideration totaling $3.3 million from Gilead upon achievement of a research plan milestone. The variable consideration was added to the transaction price and allocated to the performance obligation to determine the amount of related revenue to be recognized. A proportional amount was recognized based on the input cost to cost measurement of work completed to date.

In November 2025, the parties amended the Gilead Agreement by entering into a third letter agreement (Third Letter Agreement) under which Gilead nominated the second of the two research programs contemplated in the Gilead Agreement (Second Research Program) and the Company 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 the Company a total of $25.0 million related to the nomination and option exercise.

The Company evaluated the Third Letter Agreement under the terms of ASC 606, and concluded that it is a modification to the Gilead Agreement that results in a separate contract since the modification is for additional goods and services that are distinct and at standalone selling price. The Company determined that there is one performance obligation under the Third Letter Agreement; to grant the research term license and exploitation license. In accordance with ASC 606, the Company determined that the initial transaction price for the Second Research Program was $25.0 million, consisting of the non-refundable payment made by Gilead. The Company recognized this amount when it satisfied its performance obligation and transferred the license to Gilead during the year ended December 31, 2025. The Company is entitled to future development, regulatory and commercial milestones related to the Second Research Program should Gilead successfully develop and commercialize the molecule. These 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 Gilead and, therefore, have also been excluded from the transaction price.

In 2018, the Company entered into an asset purchase agreement with Provention Bio, Inc. (Provention) pursuant to which Provention acquired the Company’s interest in teplizumab, a monoclonal antibody being developed for the treatment of type 1 diabetes (Provention APA). The FDA approved the BLA for TZIELD (teplizumab-mzwv) in November 2022. In March 2023, the Company sold its single-digit royalty interest in TZIELD to a wholly-owned subsidiary of DRI Healthcare Trust (DRI) and received a $100.0 million payment from DRI under a Royalty Purchase Agreement. The Company retained its other economic interests related to TZIELD, including future potential regulatory and commercial milestones, as well as the right to receive a 50% share of the royalty on global net sales above a certain annual threshold. In addition, the Company was eligible to receive an additional $50.0 million if TZIELD achieved a certain level of net sales by June 30, 2026. This milestone was not achieved and has expired.

In April 2023, Sanofi S.A. (Sanofi) completed its acquisition of Provention and the Company entered into a tripartite agreement with DRI and Sanofi under which it was released of any obligations under the Royalty Purchase Agreement. In September 2023, the Company and Sanofi executed Amendment No. 2 to the Provention APA and terminated the Royalty Purchase Agreement with DRI. As a result, the remaining $50.0 million sales milestone under the Royalty Purchase Agreement was incorporated into the Provention APA.

The Company evaluated the Provention APA under the provisions of ASC 606, and determined that 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. Any consideration related to sales-based milestones will be recognized when the related sales occur. The Company re-assesses the transaction price in each reporting period and when events whose outcomes are resolved or other changes in circumstances occur.

In January 2022, the Company entered into a Manufacturing and Clinical Supply Agreement with Incyte (2022 Incyte Manufacturing and Clinical Supply Agreement) to provide manufacturing services to produce certain Incyte bulk drug substance over a three-year period. Under the terms of the 2022 Incyte Manufacturing and Clinical Supply Agreement, the Company received an upfront payment of $10.0 million and was eligible to receive annual fixed payments paid quarterly over the term of the contract totaling $14.4 million. The Company was also reimbursed for materials used to manufacture product as well as other costs incurred to provide manufacturing services. In July 2022, the Company and Incyte executed an amendment to the 2022 Incyte Manufacturing and Clinical Supply Agreement which extended the term for one year and provided for an additional annual fixed payment of $5.1 million (July 2022 Incyte Amendment). In December 2024 and March 2025, the Company and Incyte entered into letter agreements whereby Incyte reserved additional manufacturing services during 2025 with a total fixed cost of $13.5 million (Incyte Letter Agreements).

The Company evaluated the 2022 Incyte Manufacturing and Clinical Supply Agreement, the July 2022 Incyte Amendment and the Incyte Letter Agreements 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 consists of the upfront payment of $10.0 million, the annual fixed payments and the payments per batch under the Incyte Letter Agreements totaling $41.7 million. The Company recognized revenue over time on a straight-line basis as the manufacturing services were provided to Incyte, as the Company determined that its efforts in providing the manufacturing services were incurred evenly throughout the performance period and therefore straight-line revenue recognition closely approximated 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 was allocated to the related manufacturing activities and was recognized as revenue as those activities occurred. Materials purchased by the Company to manufacture the product for Incyte were considered inventory and were capitalized and expensed as the materials were used to provide the manufacturing services.

In September 2025, the Company entered into a new Manufacturing and Clinical Supply Agreement with Incyte (2025 Incyte Manufacturing and Clinical Supply Agreement) to provide manufacturing services to produce certain Incyte bulk drug substance over a three-year period beginning in January 2026. Based on the current manufacturing schedule contemplated in the 2025 Incyte Manufacturing and Clinical Supply Agreement, Incyte was to pay a total fixed cost of $16.8 million over the term of the agreement. The Company would also be reimbursed for materials used to manufacture product as well as other costs incurred to provide manufacturing services.

The Company recognized revenue over time on a straight-line basis as the manufacturing services were provided to Incyte, as the Company determined that its efforts in providing the manufacturing services were incurred evenly throughout the performance period and therefore straight-line revenue recognition closely approximated 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 was allocated to the related manufacturing activities and was recognized as revenue as those activities occurred. Materials purchased by the Company to manufacture the product for Incyte were considered inventory and were capitalized and expensed as the materials were used to provide the manufacturing services.

As described more fully in Note 11, Discontinued Operations, the Company sold its CDMO Operations as of June 30, 2026 and assigned the 2025 Incyte Manufacturing and Clinical Supply Agreement to Bora. During the three and six months ended June 30, 2026, the Company recognized revenue of $0.8 million and $4.7 million, respectively, under the 2025 Incyte Manufacturing and Clinical Supply Agreement, which is reflected in the Net income from discontinued operations, net of taxes line on the consolidated statements of operations and comprehensive income (loss).
