Acquisitions and Licensing Arrangements

Biogen Inc. (“Biogen”)

In March 2025, Organon acquired from Biogen the regulatory and commercial rights in the United States for Tofidence® (tocilizumab-bavi). Tofidence, launched in the U.S. market in May 2024, is indicated in certain patients for the treatment of moderately to severely active rheumatoid arthritis, giant cell arthritis, polyarticular juvenile idiopathic arthritis, systemic juvenile idiopathic arthritis, and COVID-19. Under the terms of the agreement with Biogen, Organon paid an upfront payment of $51 million in July 2025, and will be obligated to pay tiered royalty payments based on net sales and tiered annual net sales milestone payments of up to $45 million from a previous in-license arrangement with Bio-Thera Solutions Ltd., the product developer for Tofidence. In the first quarter of 2025, the Company recognized an intangible asset of $51 million, related to the upfront payment to Biogen, which will be amortized over 10 years.

Dermavant Sciences Ltd. (“Dermavant”)

On October 28, 2024, Organon acquired Dermavant, a company dedicated to developing and commercializing innovative therapeutics in immuno-dermatology. Dermavant’s novel product, Vtama® (tapinarof) cream, was approved by the U.S. Food and Drug Administration (the “FDA”) in May 2022 for the topical treatment of mild, moderate, and severe plaque psoriasis in adults. In December 2024, the FDA approved Vtama for the treatment of atopic dermatitis, also known as eczema, in adults and children two years of age and older. Atopic dermatitis is one of the most common inflammatory dermatological conditions in adults, presenting a higher disease burden for women compared to men. The acquisition expanded Organon’s existing portfolio of general medicines.

Consideration for Dermavant consists of the upfront payment of $175 million and a $75 million milestone payment upon regulatory approval of the atopic dermatitis indication in the United States, which was paid in the first quarter of 2025, as well as payments of up to $950 million for the achievements of certain commercial milestones, tiered royalties on net sales, and the assumption of liabilities, including certain debt obligations, which were accounted for at fair value on the acquisition date.

The transaction was accounted for as a business combination. The aggregate consideration is calculated as follows:


(in millions)
Cash consideration paid to Dermavant at closing	$	198
Fair value of contingent consideration, as of acquisition date	383
Aggregate purchase price consideration	$	581

Contingent consideration included as part of the consideration relates to potential future milestone obligations of up to $1.025 billion, including: (i) up to $75 million in cash payable upon regulatory approval, and (ii) up to $950 million for the achievements of certain commercial milestones. The fair value of the contingent consideration recognized on the acquisition date was determined using the inputs disclosed in Note 11. “Financial Instruments.” The Company reassesses its acquisition-related contingent consideration liabilities each quarter for changes in fair value.

In the second quarter of 2025, the final allocation of the consideration transferred to the assets acquired and the liabilities assumed was completed. The Company has not made any adjustments to the allocation of the consideration since initially reported in the fourth quarter of 2024.

In the first quarter of 2025, the Company paid $75 million for the regulatory milestone related to the atopic dermatitis indication of Vtama in the United States achieved during the fourth quarter of 2024, and paid $35 million related to sales-based milestones that were achieved in the fourth quarter of 2024 related to an assumed licensing agreement.

In April 2025, Health Canada approved Nduvra® (tapinarof) cream, the first in a novel class of aryl hydrocarbon receptor agonists to be approved in Canada for the topical treatment of plaque psoriasis in adults. As a result, in the second quarter of 2025, the Company reclassified the acquired IPR&D intangible asset to product and product rights and will amortize the intangible asset over nine years.

Suzhou Centergene Pharmaceuticals (“Centergene”)

Due to changes in the evolving fertility landscape in China, the Company exited its agreement with Centergene. As a result, during the first quarter of 2025, the Company recognized $6 million in Acquired in-process research and development and milestones.

Eli Lilly (“Lilly”)

As of September 30, 2025, Organon has $240 million accrued in Other noncurrent liabilities related to the probable sales-based milestones. In January 2025, the Company paid $20 million related to the milestones.

Shanghai Henlius Biotech, Inc. (“Henlius”)

In September 2025, the FDA approved Bildyos® (denosumab-nxxp) injection 60 mg/mL and Bilprevda® (denosumab-nxxp) injection 120 mg/1.7 mL, biosimilars to Prolia2 (denosumab) and Xgeva2 (denosumab), respectively, for all indications of the reference products, and the European Commission granted marketing authorization for Bildyos and Bilprevda. As a result, sales-based milestones related to the Henlius agreement were determined to be probable of being achieved and the Company recognized intangible assets of $30 million related to these milestones. The intangible assets will be amortized over 9 years.

In February 2025, Organon paid $10 million related to the milestone for the development of HLX11, an investigational biosimilar of Perjeta2 (pertuzumab), which was recognized as Acquired in-process research and development and milestones in 2024. In March 2025, the European Medicines Agency validated the marketing authorization application for HLX11.

Oss Biotech Site

In July 2025, Organon acquired the Oss Biotech manufacturing facility in the Netherlands from Merck & Co., Inc., Rahway, NJ, US (“Merck”). This agreement covers Organon’s fertility drug substance production and associated support functions. Organon is required to pay aggregate consideration of $25 million, of which $15 million was paid in July 2025 and the remaining $10 million will be paid in the first half of 2026. In addition to the purchase of the facility, the Company also paid $71 million for the purchase of the remaining inventory at the site.
