Background and Nature of Operations Background and Nature of Operations
Organon & Co. (“Organon” or the “Company”) is a global healthcare company with a mission to deliver impactful medicines and solutions for a healthier every day. With a portfolio of over 70 products across women’s health and general medicines, which includes biosimilars, Organon focuses on addressing health needs that uniquely, disproportionately or differently affect women, while expanding access to essential treatments in over 140 countries and territories. The Company sells these products through various channels including drug wholesalers and retailers, hospitals, government agencies and managed healthcare providers such as health maintenance organizations, pharmacy benefit managers and other institutions. The Company operates six manufacturing facilities, which are located in Belgium, Brazil, Indonesia, Mexico, the Netherlands and the United Kingdom (“UK”). Unless otherwise indicated, trademarks appearing in italics throughout this document are trademarks of, or are used under license by, the Organon group of companies.

Organon’s operations include the following product portfolios:

Women’s Health: Organon’s health portfolio of products is sold by prescription primarily in two therapeutic areas: contraception, with key brands such as Nexplanon® (etonogestrel implant) (sold as Implanon NXT™ in some countries outside the United States) and NuvaRing® (etonogestrel / ethinyl estradiol vaginal ring); and fertility, with key brands such as Follistim AQ® (follitropin beta injection) (marketed in most countries outside the United States as Puregon™). Nexplanon is a long-acting reversible contraceptive in a class recognized as one of the most effective types of hormonal contraception available to patients with a low long-term average cost. Organon’s other women’s health products include the Jada® System, which is intended to provide control and treatment of abnormal postpartum uterine bleeding or hemorrhage when conservative management is warranted. In January 2026 the Company divested the Jada System to Laborie Medical Technologies Corporation (“Laborie”).

General Medicines: Organon’s general medicines portfolio includes biosimilars and established brands.
Biosimilars: Organon’s current biosimilars portfolio spans across immunology and oncology related treatments. Organon’s oncology biosimilars: Ontruzant® (trastuzumab-dttb), AybintioTM1 (bevacizumab), Bildyos® (denosumab-nxxp) and Bilprevda® (denosumab-nxxp) have been launched in more than 20 countries. Organon’s immunology biosimilars consist of: BrenzysTM1 (etanercept), Renflexis® (infliximab-abda), Hadlima® (adalimumab-bwwd) and Tofidence® (tocilizumab-bavi). Brenzys, Renflexis, and Hadlima have been launched in five countries. In 2025, Organon launched Bildyos injection 60 mg/mL and Bilprevda injection 120 mg/1.7 mL, biosimilars to Prolia2 (denosumab) and Xgeva2 (denosumab), respectively, in the United States. In 2025, Poherdy® (pertuzumab-dpzb) was approved by the U.S. Food and Drug Administration (“FDA”), and the Company is assessing the future commercial launch of this product.
Established Brands: Organon has a portfolio of established brands, which includes brands in cardiovascular, respiratory, dermatology and non-opioid pain management, including Emgality®2 (galcanezumab-gnlm) and Vtama® (tapinarof) cream 1%. Many brands in the established brands portfolio lost exclusivity years ago and have faced generic competition for some time.

Summary of Accounting Policies Summary of Accounting Policies
Revenue Recognition — Recognition of revenue requires evidence of a contract, probable collection of sales proceeds and completion of substantially all performance obligations. The Company acts as the principal in its customer arrangements and therefore records revenue on a gross basis. The majority of the Company’s contracts have a single performance obligation — the promise to transfer goods. Shipping is considered immaterial in the context of the overall customer arrangement and damages or loss of goods in transit are rare. Therefore, shipping is not deemed a separately recognized performance obligation.

Revenues from sales of products, including tenders, are recognized at a point in time when control of the goods is transferred to the customer, which the Company has determined is when title and risks and rewards of ownership transfer to the customer and the Company is entitled to payment.

The nature of the Company’s business gives rise to several types of variable consideration including discounts and returns, which are estimated at the time of sale generally using the expected value method, although the most likely amount method is used for prompt pay discounts.

In the United States, sales discounts are issued to customers at the point-of-sale, through an intermediary wholesaler (known as chargebacks), or in the form of rebates. Additionally, sales are generally made with a limited right of return under certain
conditions. Revenues are recorded net of provisions for sales discounts and returns, which are established at the time of sale. In addition, revenues are recorded net of time value of money discounts if collection of accounts receivable is expected to be in excess of one year.

Chargebacks are discounts that occur when a contracted customer purchases through an intermediary wholesaler. The contracted customer generally purchases product from the wholesaler at its contracted price plus a mark-up. The wholesaler, in turn, charges the Company back for the difference between the price initially paid by the wholesaler and the contract price paid to the wholesaler by the customer. The Company estimates the provision for chargebacks based on expected sell-through levels by the Company’s wholesale customers to contracted customers, as well as estimated wholesaler inventory levels. Rebates are amounts owed based upon definitive contractual agreements or legal requirements with private sector, (Managed Care), and public sector (Medicaid and Medicare Part D) benefit providers, after the final dispensing of the product by a pharmacy to a benefit plan participant. The provision for rebates is based on expected patient usage, as well as inventory levels in the distribution channel to determine the contractual obligation to the benefit providers. The Company uses historical customer segment utilization mix, sales, changes to product mix and price, inventory levels in the distribution channel, government pricing calculations and prior payment history to estimate the expected provision.

The Company continually monitors the provision for aggregate customer discounts. There were no material adjustments to estimates associated with the aggregate customer discount provision in 2025, 2024, or 2023.

Summarized information about changes in the aggregate customer discount accrual related to sales in the United States is as follows:

Balance December 31$523 $480 $504 
(1) The year ended December 31, 2024 includes $48 million of liabilities assumed as part of the 2024 Dermavant acquisition.

Amounts accrued for aggregate customer discounts are evaluated on a quarterly basis through comparison of information provided by the wholesalers, health maintenance organizations, pharmacy benefit managers, federal and state agencies, and other customers to the amounts accrued. The accrued balances relative to the provisions for chargebacks and rebates in the United States included in Accounts receivable and Accrued and other current liabilities were $111 million and $412 million, respectively, at December 31, 2025 and $100 million and $380 million, respectively, at December 31, 2024.

Outside of the United States, variable consideration in the form of discounts and rebates is a combination of commercially-driven discounts in highly competitive product classes, discounts required to gain or maintain reimbursement, or legislatively mandated rebates. The accrued balances relative to the provision for chargebacks and rebates, based on the terms and nature of the rebate, are included in Accounts receivable and Accrued and other current liabilities. Rebates may also be required based on specific product sales thresholds. The Company applies an estimated factor against its actual invoiced sales to represent the expected level of future discount or rebate obligations associated with the sale. At December 31, 2025 and 2024, the accrued balances related to the provision for rebates and discounts included in other current liabilities were approximately $180 million and $155 million, respectively.

The Company maintains a returns policy that allows customers in certain countries to return product within a specified period prior to and subsequent to the expiration date (generally, three to six months before and 12 months after product expiration). The estimate of the provision for returns is based upon historical experience with actual returns and consideration of other relevant factors.

The Company’s payment terms are typically 30 days to 90 days, although certain markets have longer payment terms. See Note 5 “Product and Geographic Information” for disaggregated revenue disclosures.

Cash Equivalents — Cash equivalents are comprised of certain highly liquid investments with original maturities of three months or less.
Inventories — Inventories are valued at the lower of cost or net realizable value. The cost of a substantial majority of U.S. inventories is determined using the last-in, first-out (“LIFO”) method for both financial reporting and tax purposes. The cost of all other inventories is determined using the first-in, first-out (“FIFO”) method.

Value Added Tax — The Company’s purchases, sales and intercompany transfers of goods are subject to value added tax (“VAT”) and VAT receivables are recognized for amounts that represent credits against future VAT obligations. VAT receivables included in Other current assets were $102 million and $103 million as of December 31, 2025 and 2024, respectively. VAT payables included in Accrued and other current liabilities were $17 million and $11 million as of December 31, 2025 and 2024, respectively. The related expense is included in the Company’s operating expenses.

Depreciation — Depreciation is provided over the estimated useful lives of the assets, principally using the straight-line method. The estimated useful lives primarily range from 25 to 40 years for buildings, and from 3 to 15 years for machinery, equipment and office furnishings. Depreciation expense was $156 million in 2025, $132 million in 2024, and $120 million in 2023. Repairs and maintenance costs are expensed as incurred as they do not extend the economic life of an asset.

Advertising and Promotion Costs — Advertising and promotion costs are expensed as incurred and included in Selling, general and administrative expenses. The Company recorded advertising and promotion expenses of $240 million, $206 million, and $209 million in 2025, 2024 and 2023, respectively.

Goodwill — Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses acquired. Goodwill is evaluated for impairment each year in the fourth quarter, or more frequently if impairment indicators exist, by first assessing qualitative factors to determine whether it is more likely than not that fair value is less than carrying value. If the Company concludes it is more likely than not that fair value is less than carrying value, a quantitative fair value test is performed. If carrying value is greater than fair value, a goodwill impairment charge will be recorded for the difference (up to the carrying value of goodwill).

The Company estimates the fair value of a reporting unit using a discounted cash flow model which relies on projected cash flows and market assumptions. Key assumptions used in projected cash flows include projected revenue growth rates, cost of sales, selling, general and administrative expenses, terminal growth rates, and discount rates. These assumptions require significant judgment and are based on best estimates of future economic and market conditions. A significant decline in forecasted performance, whether due to external economic factors or internal operational challenges, could result in the fair value of either the U.S. or International reporting unit falling below its carrying amount. In such cases, the Company would be required to recognize a non-cash impairment charge, which could materially impact our financial condition and results of operations. Additionally, the Company may be required to record impairment charges on goodwill related to a reporting unit if adverse macroeconomic or geopolitical developments materially affect our business outlook. These developments may include, but are not limited to, the implementation of tariffs, changes in trade policies, inflationary pressures, supply chain disruptions, or regulatory changes that reduce forecasts or increase operating costs. See Note 11 “Intangibles and Goodwill” for additional details.

Intangibles — Intangibles include products and product rights and licenses, which are initially recorded at fair value, assigned an estimated useful life, and amortized on a straight-line basis over their estimated useful lives. Licenses include milestone payments made to collaborative partners upon or subsequent to regulatory approval. The estimated useful lives of intangibles range from 5 to 15 years. The Company periodically evaluates whether current facts or circumstances indicate that the carrying values of its intangibles may not be recoverable. If such circumstances are determined to exist, an estimate of the undiscounted future cash flows of these assets, or appropriate asset groupings, is compared to the carrying value to determine whether an impairment exists. If the asset is determined to be impaired, the loss is measured based on the difference between the carrying value of the intangible asset and its fair value, which is determined based on the net present value of estimated future cash flows. See Note 11 “Intangibles and Goodwill” for additional details.

Acquired In-Process Research and Development (“IPR&D”) — IPR&D that the Company acquires in conjunction with the acquisition of a business represents the fair value assigned to incomplete research projects which, at the time of acquisition, have not reached technological feasibility. The amounts are capitalized and are accounted for as indefinite-lived intangible assets, subject to impairment testing until completion or abandonment of the projects. Upon successful completion of each project, Organon will make a determination as to the then-useful life of the intangible asset, generally determined by the period in which the substantial majority of the cash flows are expected to be generated, and begin amortization. The Company evaluates IPR&D for impairment as of October 1 each year, or more frequently if impairment indicators exist and it is more likely than not that the fair value is less than its carrying amount, by performing a quantitative test that compares the fair value of the IPR&D intangible asset with its carrying value. If the fair value is less than the carrying amount, an impairment loss is recognized in operating results. See Note 11 “Intangibles and Goodwill” for additional details.
Contingent Consideration — For transactions accounted for as a business acquisition, contingent consideration liabilities are recognized at the estimated fair value on the acquisition date. Subsequent changes to the fair value of contingent consideration liabilities are recognized in Other expense, net in the Consolidated Statements of Income. Contingent consideration payments made or received soon after the acquisition date are classified as Investing activities in the Consolidated Statements of Cash Flows. Contingent consideration payments not made or received soon after the acquisition date that are related to the acquisition date fair value are reported as Financing activities in the Consolidated Statements of Cash Flows, and amounts paid or received in excess of the original acquisition date fair value are reported as Operating activities in the Consolidated Statements of Cash Flows. For transactions accounted for as an asset acquisition, contingent consideration liabilities that are payable prior to regulatory approval are recognized in Acquired in-process research and development and milestones in the Consolidated Statements of Income when achievement of the milestone is deemed probable. Contingent consideration liabilities that are payable on or after regulatory approval are capitalized as intangible assets when the payments have become probable and amortized to Cost of sales over the remaining useful life of the related intangible assets.

Research and Development — Research and development costs associated with clinical development programs that have not yet received regulatory approval are expensed as incurred.

Acquired in-process research and development and milestones Acquired IPR&D and milestones includes upfront and milestone payments, related to asset acquisitions, licensing or collaborative arrangements that are not considered an acquisition of a business and involve clinical development programs that have not yet received regulatory approval.

Foreign Currency Transaction and Translation — Transactions denominated in a currency other than the entity's functional currency is considered a foreign currency transaction. Foreign currency transactions may produce cash, receivables or payables which are fixed in terms of the amount of foreign currency to be received/paid. A change in exchange rate before settlement between the functional currency and the currency in which the transaction is denominated is included in net income in the period of exchange rate change as Exchange losses. The net assets of international operations where the local currencies have been determined to be the functional currencies are translated into U.S. dollars using current exchange rates. The U.S. dollar effects that arise from translating the net assets of these subsidiaries at changing rates are recorded in the foreign currency translation account, which is included in Accumulated other comprehensive loss and reflected as a separate component of equity. For those operations that operate in highly inflationary economies and for those operations where the U.S. dollar has been determined to be the functional currency, non-monetary foreign currency assets and liabilities are translated using historical rates, while monetary assets and liabilities are translated at current rates, with the U.S. dollar effects of rate changes included in Exchange losses.

Stock-Based Compensation — Effective June 3, 2021, Organon established the 2021 Incentive Stock Plan (the “Plan”). A total of 42.8 million shares of Common Stock are authorized under the Plan, reflecting an increase of 7.8 million shares approved in the Company’s 2025 Proxy Statement. The plan provides for the grant of various types of awards, including restricted stock unit awards, stock appreciation rights, stock options, performance-based awards and cash awards. Under the Plan, the exercise price of awards, if any, is set on the grant date and may not be less than the fair market value per share on that date. The Company measures stock-based compensation for equity awards at fair value on the date of grant and records stock-based compensation as a charge to earnings net of the estimated impact of forfeited awards. Accordingly, the Company recognizes stock-based compensation cost only for those stock-based awards that are estimated to ultimately vest over their requisite service period, based on the vesting provisions of the individual grants. The cumulative effect on current and prior periods of a change in the estimated forfeiture rate is recognized as compensation cost in earnings in the period of the change. See Note 6 “Stock-Based Compensation Plans” for additional details.

Pension and Other Postretirement Benefit Plans — For certain defined benefit plans, the over funded or underfunded status of the plan was recognized as an asset or liability on the consolidated balance sheet. Organon sponsors certain non-U.S. defined benefit pension plans. See Note 14 “Pension and Other Postretirement Benefit Plans” for additional details.

Restructuring Costs — Costs associated with exit or disposal activities are recognized in the period in which they are incurred. Costs for one-time termination benefits in which the employee is required to render service until termination in order to receive the benefits are recognized ratably over the future service period. In accordance with existing benefit arrangements, future employee termination costs to be incurred in conjunction with involuntary separations are accrued when such separations are probable and estimable.

Contingencies and Legal Defense Costs — The Company records accruals for contingencies and legal defense costs expected to be incurred in connection with a loss contingency when it is probable that a liability has been incurred and the amount can be reasonably estimated.
Taxes on Income — Deferred taxes are recognized for the future tax effects of temporary differences between financial and income tax reporting based on enacted tax laws and rates. The Company establishes valuation allowances for its deferred tax assets when the amount of expected future income is not likely to support the use of the deduction or credit. The Company assesses all available evidence to estimate whether a valuation allowance should be recorded against existing deferred tax assets. The amounts of the deferred tax asset considered realizable, however, could be adjusted in future periods if estimates of future income are reduced or increased.

The Company evaluates tax positions to determine whether the benefits of tax positions are more likely than not of being sustained upon audit based on the technical merits of the tax position. For tax positions that are more likely than not of being sustained upon audit, the Company recognizes the largest amount of the benefit that is greater than 50% likely of being realized upon ultimate settlement in the Consolidated Financial Statements. For tax positions that are not more likely than not of being sustained upon audit, the Company does not recognize any portion of the benefit in the Consolidated Financial Statements.

The Company recognizes interest and penalties associated with uncertain tax positions as a component of Taxes on Income in the Consolidated Statement of Income. The Company accounts for the tax effects of the tax on global intangible low-taxed income of certain foreign subsidiaries in the income tax provision in the period the tax arises. The Company and Merck entered into the Tax Matters Agreement in connection with the Separation. See Note 17 “Third-Party Arrangements” for additional details and defined terms.

Leases — The Company has operating leases primarily for real estate. The Company determines if an arrangement is a lease at inception. When evaluating contracts for embedded leases, the Company exercises judgment to determine if there is an explicit or implicit identified asset in the contract and if the Company controls the use of that asset. Embedded leases are immaterial. The lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company has made an accounting policy election not to record short-term leases (leases with an initial term of 12 months or less) on the balance sheet. Lease expense associated with short term leases is not material for all periods presented.

Lease expense for operating lease payments is recognized on a straight-line basis over the term of the lease. Operating lease assets and liabilities are recognized based on the present value of lease payments over the lease term. Since most of the Company’s leases do not have a readily determinable implicit discount rate, the Company uses its incremental borrowing rate to calculate the present value of lease payments. On a quarterly basis, an updated incremental borrowing rate is determined based on the weighted average remaining lease term of each asset class and the Company’s pretax cost of debt for that same term. The updated rates for each asset class are applied prospectively to new leases. The Company does not separate lease components (e.g., payments for rent) from non-lease components (e.g., common-area maintenance costs) in the event that the agreement contains both. The Company includes both the lease and fixed non-lease components for purposes of calculating the lease liability and the related right-of-use asset. See Note 12 “Long-Term Debt, Short Term Borrowings and Leases” for additional details.

Principles of Consolidation — The consolidated financial statements include the accounts of the Company and all of its subsidiaries. All intercompany transactions and accounts have been eliminated.

Use of Estimates — The presentation of these Consolidated Financial Statements and accompanying notes in conformity with U.S. GAAP require management to make estimates and assumptions that affect the amounts reported. Estimates are used in determining such items as provisions for sales discounts and returns, depreciable and amortizable lives, recoverability of inventories, amounts recorded for contingencies, environmental liabilities, pension and other postretirement benefit plan assumptions, stock-based compensation assumptions, restructuring costs, impairments of long-lived or indefinite-lived assets (including intangible assets and goodwill), investments, and taxes on income. Additionally, estimates are used in acquisitions, including initial fair value determinations of assets and liabilities (primarily IPR&D, intangible assets and contingent consideration), as well as subsequent fair value measurements.

Segments — The Company operates as one operating segment comprised of two reporting units: U.S. and International. Organon is engaged in developing and delivering innovative health solutions through its portfolio of prescription therapies within women's health and general medicines. The Company’s chief operating decision‑maker (the “CODM”) is the Interim Chief Executive Officer. The CODM assesses performance and decides how to allocate resources for our one operating segment based on consolidated net income that is reported on the consolidated statements of income. The Company has also evaluated the significant segment expenses incurred by our single segment and regularly provided to the CODM. The significant segment expenses provided to the CODM are consistent with those reported on the Consolidated Statements of Income and include cost of sales, selling, general and administrative, research and development, interest expense and income
taxes. The CODM uses these metrics to make key operating decisions such as: approving a new product launch strategy, making significant capital expenditures, approving the design of key commercialization strategies, decisions about key personnel, and approving annual operating and capital budgets. Our CODM considers budget-to-actual variances and year over year performance when making decisions supporting capital resource allocation. The Company manages assets on a consolidated basis as reported on the consolidated balance sheets.

2025 Transactions

Biogen Inc. (“Biogen”)

In March 2025, Organon acquired from Biogen the regulatory and commercial rights in the United States for Tofidence. 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 arteritis, 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 is 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.

Shanghai Henlius Biotech, Inc. (“Henlius”)

In November 2025, the FDA approved the Biologics License Application for Poherdy 420 mg/14 mL injection for intravenous use, an interchangeable biosimilar to Perjeta2 (pertuzumab), for all indications of the reference product. The Company is assessing the future commercial launch of the product.

In the third quarter of 2025, the FDA approved Bildyos injection 60 mg/mL and Bilprevda injection 120 mg/1.7 mL, biosimilars to Prolia and Xgeva, 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 nine years. As of December 31, 2025, Organon paid $20 million related to these milestones.
In February 2025, Organon paid $10 million related to the milestone for the development of HLX11, an investigational biosimilar of Perjeta, 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, U.S. (“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.

2024 Transactions

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 was approved by 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 date383
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 13 “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 did not make any adjustments to the allocation of the consideration since initially reported in the fourth quarter of 2024.
The following table summarizes the fair values of the assets acquired and liabilities assumed related to the Dermavant acquisition as of the acquisition date:

($ in millions)
Cash and cash equivalents$31 
Accounts receivable46 
Inventories 97 
Other assets36 
Intangibles672 
Long-term debt(258)
Other liabilities(108)
Deferred income taxes(12)
Total identifiable net assets 504 
Goodwill77 
Purchase Consideration$581 

The carrying values of cash and cash equivalents, accounts receivables, raw materials inventory, other assets and other liabilities represented their fair values at the date of acquisition.

The fair value of finished goods inventory was determined based on its net realizable based on the estimated selling price adjusted for cost of the selling effort and a reasonable profit allowance for the selling effort.

The fair value of the identifiable intangible assets was determined primarily using the “income approach,” which requires a forecast of the expected future cash flows (including net revenue, cost of sales, operating expenses) and the appropriate discount rate.

The intangible assets acquired, as well as their fair values and estimated useful life consist of the following:
($ in millions)Fair Value Estimated Useful Life
(in years)

Vtama - Plaque Psoriasis
$216 11

61 N/A
$672 
(1) 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. As a result, the Company reclassified the Vtama - Atopic Dermatitis acquired IPR&D intangible asset to product and product rights.

The fair value of the assumed debt was determined using the option-pricing model which is determined using expected payments and timing of payments, and a discount rate.

The fair value measurement of contingent consideration arising from business combinations was determined via a probability-weighted cash flows using a Monte Carlo simulation model which was then discounted to present value. These inputs may include: (i) the estimated amount and timing of projected cash flows, (ii) the probability of the achievement of the factor(s) on which the contingency is based and (iii) the risk-adjusted discount rate used to present value the probability-weighted cash flows.

The excess of the consideration paid over the fair value of the net assets acquired was recorded as goodwill. The goodwill recognized upon acquisition is not deductible for income tax purposes.

In December 2024, the FDA approved Vtama for atopic dermatitis. As a result, the Company transferred the IPR&D amount of $395 million to Currently marketed products – products and product rights and will amortize the asset over 11 years.
During the fourth quarter of 2024, the regulatory milestone related to the atopic dermatitis indication of Vtama, which was recorded as part of contingent consideration at fair value, was achieved and recorded in Accrued and other current liabilities.

During the fourth quarter of 2024, Organon recognized an additional intangible asset of $24 million, related to a sales-based milestone that was deemed probable and was related to an assumed licensing agreement. The intangible asset will be amortized over 11 years.

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.

Unaudited Pro forma Information

The unaudited pro forma combined financial information was prepared using the acquisition method of accounting and was based on the historical financial information of Organon and Dermavant. The unaudited pro forma financial information includes adjustments to reflect incremental amortization expense to be incurred based on the current preliminary fair values of the identifiable intangible assets acquired; the incremental cost of sales related to the fair value adjustments associated with acquisition date inventory; and the reclassification of acquisition-related costs incurred during the year ended December 31, 2024 to the year ended December 31, 2023. The unaudited pro forma financial information is not necessarily indicative of what the consolidated results of operations would have been had the acquisition been completed on January 1, 2023. In addition, the unaudited pro forma financial information is not a projection of future results of operations of the combined Company nor does it reflect the expected realization of any synergies or cost savings associated with the acquisition.

Transactions Costs

Organon incurred costs associated with the Dermavant transaction of approximately $12 million, comprised of transaction fees and legal costs and were recognized in Selling, general and administrative expenses for the year ended December 31, 2024.
Suzhou Centergene Pharmaceuticals (“Centergene”)

In September 2024, we entered into license and supply agreements with Centergene, pursuant to which we acquired the exclusive commercialization rights to Centergene’s investigational asset, SJ02, in China. 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”)

In December 2023, Organon announced an agreement with Lilly to become the sole distributor and promoter of the migraine medicine Emgality in Europe. Lilly will remain the marketing authorization holder and will manufacture the products for sale. Under the terms of the agreement, Organon paid an upfront payment of $50 million upon closing of the transaction in January 2024, and will recognize sales-based milestones when the achievement is deemed probable. In the first quarter of 2024, the Company recognized an intangible asset of $220 million, comprised of the $50 million upfront payment and $170 million of sales-based milestones that were deemed probable. The intangible asset will be amortized over 10 years.

In August of 2024, Organon expanded its agreement with Lilly to become the sole distributor and promoter for Emgality in the following additional markets: Canada, Colombia, Israel, South Korea, Kuwait, Mexico, Qatar, Saudi Arabia, Taiwan, Turkey, and the United Arab Emirates. Organon paid an upfront payment of $23 million for the expansion of territory upon closing of the transaction in August 2024, and will recognize sales-based milestones when the achievement is deemed probable. In the third quarter of 2024, Organon recognized an additional intangible asset of $113 million, comprised of the $23 million upfront payment and $90 million related to the sales-based milestones that were deemed probable. The intangible asset will be amortized over 10 years.

As of December 31, 2025, Organon has $50 million accrued in Accrued and other current liabilities and $190 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.

Cirqle Biomedical (“Cirqle”)

In July 2022, the Company entered into a research collaboration and license agreement with Cirqle for a novel investigational non-hormonal, on-demand contraceptive candidate. Under the terms of the agreement, Cirqle is responsible for conducting preclinical studies according to the mutually agreed research plan. Organon obtained exclusive worldwide rights to develop and commercialize the asset. For the year ended December 31, 2024, research and development milestones related to the Cirqle agreement were determined to be probable of being achieved and the Company expensed and paid $10 million in Acquired in-process research and development and milestones expense.

Employee stock options are granted to purchase shares of Company common stock at the fair market value at the time of grant. Generally, stock options have a contractual term of ten years and vest one-third each year over a three-year period, subject to limited exceptions.

RSUs are stock awards that are granted to employees and entitle the holder to shares of common stock as the awards vest. RSU awards generally vest one-third each year over a three-year period. The fair value of the stock option and RSU awards is determined and fixed on the grant date based on the Company’s stock price.

The terms of the Company’s PSU awards allow the recipients of such awards to earn a variable number of common shares based on the cumulative results of specified performance factors.

The PSU awards are based on the following performance factors:
total stockholder return (“TSR”) of the Company relative to an index of peer companies specified in the awards; and
the results of cumulative free cash flow (“FCF”) and revenue metrics of the Company.

PSUs include awards issued where the service inception date precedes the grant date. The grant date for the performance conditions is the date grantees have a mutual understanding of the key terms and conditions of the award, which will occur when the performance condition is objectively determinable and measurable. Recognition of stock-based compensation occurs at the service inception date. Measurement of stock-based compensation attributed to the PSU’s will be based on the fair value once the grant date is determined.

For FCF and relative TSR awards, the Company recognizes compensation costs ratably over the performance period. The PSU awards will generally vest at the end of the three year performance period, however, the number of shares delivered will vary based upon the attained level of performance. For PSUs with a performance-based FCF goal, stock-based compensation expense is recognized based on the probability of the achievement of the financial performance metric for the respective vesting period and is assessed at each reporting date. For PSUs with a market-based relative TSR goal, stock-based compensation expense is recognized based on the estimated fair value of the award at the grant date regardless of the actual number of shares earned. PSU awards generally vest after three years. The Company uses the Monte Carlo simulation to determine the fair value of the relative TSR awards as of the grant date.

For RSUs and PSUs, dividends declared during the vesting period are payable to the employees only upon vesting. RSU and PSU distributions will be in shares of Company Common Stock after the end of the vesting or performance period, subject to the terms applicable to such awards.
Cash awards will be recognized and expensed over their vesting period at the fair market value of the shares on the date they are awarded and will be remeasured on a quarterly basis until the award vests or is otherwise settled.

Stock-based compensation expenses incurred by the Company were as follows:

The Company uses the Black-Scholes model to determine the fair value of the stock options as of the grant date. In applying this model, the Company uses both historical data and current market data to estimate the fair value of its options. The expected dividend yield is based on forecasted patterns of dividend payments. The risk-free interest rate is based on the rate at grant date of zero-coupon U.S. Treasury Notes with a term equal to the expected term of the option. Expected volatility is estimated using historical volatility.

In 2025 and 2024, the historical component of expected volatility is based on the historical monthly price changes of Organon and implied volatility of Organon. In 2023, due to the lack of trading history of Organon’s stock at the time of valuation efforts, the historical component of expected volatility is based on historical monthly price changes of a combination of the peer group within the industry and Organon’s historical monthly price changes. The expected term represents the amount of time that options granted are expected to be outstanding based on historical and forecasted exercise behavior.

The fair value of options granted was determined using the following assumptions:

Restructuring and Related Activities [Abstract]  
Restructuring Restructuring
During the first quarter of 2025, we implemented additional restructuring initiatives to drive an enterprise-wide operating model optimization that resulted in an approximate 6% headcount reduction. The restructuring activities were initiated to streamline and simplify the Company’s operating model to create more efficient processes and a simplified structure. Restructuring costs include separation costs associated with manufacturing-related headcount reductions.

In prior years, Organon implemented restructuring activities related to the optimization of its internal operations by reducing headcount. As a result of these combined activities, the Company’s headcount was reduced by approximately 5% by the end of 2024.

The following is a summary of changes in severance liabilities related to the restructuring activities included within Accrued and other current liabilities:

As a result of the Tax Cuts and Jobs Act (“TCJA”), the Company has made a determination it is no longer indefinitely reinvested with respect to a majority of its previously taxed undistributed earnings from foreign subsidiaries and provided for a deferred tax liability for withholding taxes due upon future remittances, net of certain foreign income tax credits. As of December 31, 2025 and 2023, the deferred tax balance was $2 million and $4 million, respectively. As of December 31, 2024, there was no deferred tax balance.

The tax effects of foreign earnings in the tax rate reconciliation above primarily reflect the effects of operations in jurisdictions with different tax rates than the United States thereby yielding a favorable impact on the effective tax rate compared with the U.S. statutory rate of 21%. The favorable impact is primarily attributable to a reduced tax rate arrangement that was agreed to in Switzerland for an active legal entity

The effective income tax rates were 56.0%, (7.1)% and (52.2)% for 2025, 2024 and 2023, respectively. These effective income tax rates reflect the beneficial impact of foreign earnings, offset by the impact of U.S. inclusions under the Global Intangible Low-Taxed Income regime and a valuation allowance recorded against non-deductible U.S. interest expense.

The 2025 effective tax rate was driven higher by a non-deductible goodwill impairment and an investment basis difference on the sale of the Jada System, offset by the favorable impact of a tax amortization benefit. In the third quarter of 2024, the Swiss tax authority confirmed to the Company the applicable useful life of an existing tax asset. As a result, the Company has now concluded it is more likely than not it will utilize the entirety of the tax asset. As such, the Company released a $210 million related valuation allowance. In the fourth quarter of 2023, $476 million tax benefit was recorded, comprised of a gross benefit of $686 million, net of a $210 million valuation allowance, resulting from the termination of a tax arrangement in Switzerland.

The Company has recognized $229 million and $224 million of deferred taxes on net operating loss (“NOL”) carryforwards in multiple jurisdictions as of December 31, 2025 and 2024, respectively. Valuation allowances of $310 million have been established on $170 million of foreign deferred tax assets and $140 million of U.S. deferred tax assets. The additions charged to expense are related to the U.S. disallowed interest expense carryforward. The reductions charged to expense of $11 million is primarily due to the $11 million release of a valuation allowance established on net operating losses, which expired in 2025. The remaining $1 million change is related to currency translation on certain non-US valuation allowances whose functional currencies are not the US dollar.

If the Company were to recognize the unrecognized tax benefits of $160 million, at December 31, 2025, the income tax provision would reflect a favorable net impact of $160 million.

In 2024 and 2023, foreign tax authorities concluded their examinations of certain foreign income tax returns. As a result, the Company reflected a payment of $27 million and $7 million in the consolidated financial statements in 2024 and 2023, respectively. A corresponding reduction in reserves of $27 million and $15 million were also reflected in 2024 and 2023, respectively, for unrecognized tax benefits for tax positions relating to the years that were under examination.

Interest and penalties associated with uncertain tax positions resulted in an expense of $12 million in 2025, a benefit of $15 million in 2024 and an expense of $3 million in 2023. These amounts reflect the beneficial impacts of various tax settlements. Liabilities for accrued interest and penalties were $30 million and $20 million as of December 31, 2025 and 2024, respectively.

Various foreign tax examinations are in progress and for these jurisdictions, income tax returns are open for examination for the period 2008 through 2025.

Following a change in executive leadership in the second quarter, the Company reassessed its segment reporting structure and determined that it operates as one operating segment comprised of two reporting units: U.S. and International. In conjunction with the segment assessment in the second quarter, the Company performed an impairment analysis and determined there was no impairment.

In the fourth quarter of 2025, the Company performed their impairment assessment and determined that the fair value of the U.S. reporting unit was below its carrying value, indicating that goodwill was impaired. The goodwill impairment resulted from the decline of the Company’s patent protected products in the U.S. in the fourth quarter for 2025 that is expected to result in a continuing impact on the products’ future forecast. The decline in fair value reflects continued pressure on the U.S. reporting unit resulting from lower-than-expected financial performance primarily from our patent-protected products, revised forward-looking projections, adverse geopolitical development market conditions, and uncertainty in the macroeconomic environment.

Accordingly, the Company recorded a goodwill impairment charge of $301 million during the fourth quarter of 2025, which represents the amount by which the carrying value of goodwill exceeded its implied fair value, or 11.7% of the reporting unit’s carrying amount. The impairment charge is included in Goodwill impairment in the Consolidated Statements of Income and resulted in a corresponding reduction of Goodwill.

The U.S. reporting unit that was impaired as of the fourth quarter 2025 impairment test was written down to its respective fair value, resulting in zero excess fair value over carrying amount. The U.S. reporting unit had an aggregate goodwill carrying amount of $921 million after the impairment change and therefore any adverse changes to the key assumptions or operating results could result in additional impairment charges. The international reporting unit had less than 20% fair value over carrying amount with an aggregate goodwill carrying amount of $3.2 billion. As a result, the U.S. reporting unit is more susceptible to future impairment than the International reporting unit.
In estimating the fair value of the U.S. and International reporting units, management utilized several key assumptions. This includes a discount rate of 13.5% and 15%, respectively, and a long term growth rate of 0% for both reporting units. Changes in these assumptions could materially affect the estimated fair value of the U.S. reporting unit and result in additional impairment in future periods

Senior Credit Agreement

On June 2, 2021, Organon entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent and collateral agent (the “Senior Credit Agreement”), providing for:

a Term Loan B Facility (“Term Loan B Facility”), consisting of (i) a U.S. dollar denominated senior secured “tranche B” term loan (“U.S. Dollar Term Loan Facility”) in the amount of $3.0 billion, and (ii) a euro denominated senior secured “tranche B” term loan (“Euro Term Loan Facility”) in the amount of €750 million, in each case with a seven-year term that matures in 2028; and
a Revolving Credit Facility (“Revolving Credit Facility” and, together with the Term Loan B Facility, the “Senior Credit Facilities”), in an aggregate principal amount of up to $1 billion, with a five-year term that matures in 2026.

On May 17, 2024, Organon entered into Amendment No. 2 to the Senior Credit Agreement (“Amendment No. 2”) which, among other things, (i) extended the maturity of the U.S. Dollar Term Loan Facility to May 17, 2031, (ii) extended the maturity of the revolving credit loans made under the Revolving Credit Facility to December 2, 2027, (iii) increased the maximum amount of the Revolving Credit Facility by $300 million and decreased the commitment fee payable in respect of the Revolving Credit Facility to 0.375%, (iv) removed the credit spread adjustment applicable to SOFR loans, and (v) reduced the interest rate in respect of the remaining $1.55 billion of loans under the U.S. Dollar Term Loan Facility (the “U.S. Dollar Term Loans”) from Term SOFR plus 3.0% to Term SOFR plus 2.50%.

On December 20, 2024, Organon entered into Amendment No. 3 to the Senior Credit Agreement (“Amendment No. 3”) which, among other things, (i) reduced the interest rate of the outstanding U.S. Dollar Term Loans from Term SOFR plus 2.50% to Term SOFR plus 2.25%, (ii) reduced the interest rate of the loans outstanding under the Euro Term Loan Facility (the “EUR Term Loans” and, together with the U.S. Dollar Term Loans, the “Term Loans”) from EURIBOR plus 3.0% to EURIBOR plus 2.75%, (iii) extended the maturity of the Euro Term Loan Facility to December 20, 2031, (iv) reduced the interest rate under the Revolving Credit Facility from Term SOFR plus 2.00% to Term SOFR plus 1.50%.
Borrowings made under the Senior Credit Agreement bear interest, in the case of:

term loans under the Term Loan B Facility (i) denominated in U.S. Dollars, at 2.25% in excess of Term SOFR (subject to a floor of 0.50%), or 1.25% in excess of an alternate base rate (“ABR”), at Organon’s option and (ii) denominated in euros, at 2.75% in excess of EURIBOR (subject to a floor of 0.00%); and
revolving loans under the Revolving Credit Facility (i) in U.S. Dollars, at 1.50% in excess of Term SOFR (subject to a floor of 0.00%), or 0.50% in excess of ABR, at Organon’s option and (ii) in euros, at 1.50% in excess of EURIBOR.

Interest payments on the Term Loans are due monthly or quarterly, depending on the interest period selected. Principal payments on the Term Loans were based on 0.25% of the original principal amount outstanding on the closing date of the Senior Credit Agreement and due on the last business day of each March, June, September and December, commencing with the last business day of September 2021 (the “Principal Payments”). These Principal Payments are reduced by the amount of any prepayments. As a result of discretionary prepayments, the quarterly Principal Payments on the U.S. Dollar Term Loans are no longer required. Effective as of the December 20, 2024 closing date of Amendment No. 3, Principal Payments on the Euro Term Loans are based on the principal amount outstanding on the Amendment No. 3 effective date, which was €725.6 million. As a result of the prepayment to the Euro Term Loan Facility described below, the next quarterly Principal Payment will not be due until June 30, 2027.

On February 6, 2026, the Company made mandatory prepayments from the proceeds of the Jada System divestiture of $20.4 million on the U.S. Dollar Term Loans and €9.6 million on the Euro Term Loan Facility. Additional mandatory prepayments totaling $55 million are required across the Company’s senior secured notes within 450 days of the January 2026 closing of the Jada System divestiture. The Company expects the remaining net proceeds will be allocated to voluntary prepayments of outstanding debt.

On June 26, 2024, the Company made a discretionary prepayment of $7.5 million on the U.S. Dollar Term Loans.

For the year ended December 31, 2025 the Company had borrowings and repayments on the revolver of $1.1 billion and $1.1 billion, respectively. There were no outstanding balances under the Revolving Credit Facility as of December 31, 2025 or December 31, 2024.

The Senior Credit Agreement contains customary financial covenants, including a total leverage ratio covenant, which measures the ratio of (i) consolidated total debt to (ii) consolidated earnings before interest, taxes, depreciation and amortization, and subject to other adjustments, that must meet certain defined limits which are tested on a quarterly basis. In addition, the Senior Credit Agreement contains covenants that limit, among other things, Organon’s ability to prepay, redeem or repurchase its subordinated and junior lien debt, incur additional debt, make acquisitions, merge with other entities, pay dividends or distributions, redeem or repurchase equity interests, and create or become subject to liens. As of December 31, 2025, the Company is in compliance with all financial covenants and no default or event of default has occurred.

Notes

In April 2021, Organon Finance 1 LLC (“Organon Finance 1”), a subsidiary of Merck, issued €1.25 billion aggregate principal amount of 2.875% senior secured notes due 2028, $2.1 billion aggregate principal amount of 4.125% senior secured notes due 2028 and $2.0 billion aggregate principal amount of 5.125% senior unsecured notes due 2031 (collectively, the “Notes”). Interest payments are due semiannually on October 30 and April 30. As part of the Separation, on June 2, 2021, Organon and a wholly-owned Dutch subsidiary of Organon, (the “Dutch Co-Issuer”) assumed the obligations under the Notes as co-issuers, Organon Finance 1 was released as an obligor under the Notes, and certain subsidiaries of Organon agreed to guarantee the Notes. Each series of Notes was issued pursuant to an indenture dated April 22, 2021, between Organon and U.S. Bank National Association. Organon and the Dutch Co-Issuer assumed the obligations under the Notes pursuant to a first supplemental indenture to the relevant indenture, and the guarantors agreed to guarantee the Notes pursuant to a second supplemental indenture to the relevant indenture.

During the second quarter of 2024, Organon issued $500 million of 6.750% senior secured notes due 2034 (the “2034 Secured Notes”) and $500 million of 7.875% senior unsecured notes due 2034 (the “2034 Unsecured Notes” and, together with the Secured Notes the “2034 Notes”). Each series of notes is guaranteed by each of the entities that guarantees the Companies’ existing senior secured credit facilities (the “Credit Facilities”). Organon used the net proceeds from the sale of the 2034 Notes to repay a portion of its borrowings under the Credit Facilities’ U.S. dollar-denominated “tranche B” term loan and to pay the fees and expenses incurred in connection with the foregoing.

As of December 31, 2024, the Company recorded approximately $38 million of deferred debt issuance costs and discounts
related to the 2034 Notes, Amendment No. 2 and Amendment No. 3. Debt issuance costs and discounts are presented as a reduction of debt on the Consolidated Balance Sheets and are amortized as a component of interest expense over the term on the related debt using the effective interest method.

During the fourth quarter of 2025, the Company repurchased and cancelled $177 million of the Company’s 5.125% notes due in 2031 (“the 2031 Notes”) prior to maturity which resulted in a pre-tax gain on extinguishment of debt of $27 million, recorded in Other (income) expense, net in the Consolidated Statements of Income for the year ended December 31, 2025.

During the second quarter of 2025, the Company repurchased and cancelled $242 million of the Company’s 5.125% notes due in 2031 (“the 2031 Notes”) prior to maturity which resulted in a pre-tax gain on extinguishment of debt of $42 million, recorded in Other (income) expense, net in the Consolidated Statements of Income for the year ended December 31, 2025.

Revenue Interest Purchase and Sale Agreement

In connection with the Dermavant acquisition, Organon assumed a revenue interest purchase and sale agreement (the “RIPSA”) with XYQ Luxco, NovaQuest Co-Investment Fund XVII, L.P., an affiliate of NovaQuest Capital Management, LLC, and MAM Tapir Lender, LLC, an affiliate of Marathon Asset Management, L.P., together with U.S. Bank National Association, as collateral agent. Under the terms of the RIPSA, Organon is obligated to pay quarterly royalties equal to $1.5 million through 2026. After 2026, quarterly royalties are based on a capped single-digit revenue interest in net sales of Vtama for all dermatological indications in the United States. Aggregate royalty payments under the RIPSA are capped at $344 million.

The RIPSA is accounted for as debt and was initially recognized at fair value of $156 million. Over the term of the arrangement, the effective interest rate will be updated prospectively each reporting period based on the carrying amount of the debt, and the estimated timing and remaining cash flows related to the debt.

Funding Agreement with NovaQuest

In connection with the Dermavant acquisition, Organon assumed the funding agreement with NovaQuest Co-Investment Fund VIII, L.P. (“NovaQuest”). Under the agreement, Organon was required to make quarterly payments totaling $118 million in aggregate, to be paid through 2028, with payments totaling $6 million in 2025, $21 million in 2026, $57 million in 2027 and $34 million in 2028. The debt was initially recognized at fair value of $102 million.

During the second quarter of 2025, the Company voluntarily repaid and terminated the funding agreement with NovaQuest (the “NovaQuest Funding Agreement”) valued at $103 million. The termination resulted in a pre-tax gain on extinguishment of debt of $4 million, recorded in Other (income) expense, net in the Consolidated Statements of Income for the year ended December 31, 2025.

Long-term debt was recorded at the carrying amount. The estimated fair value of long-term debt (including current portion) is as follows:

Level 2 was estimated using inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly for substantially the full term of the liability. Level 3 was estimated using unobservable inputs.

The Company made interest payments related to its debt instruments of $463 million for the year ended December 31, 2025. The average maturity of the Company’s long-term debt as of December 31, 2025 is approximately 4.5 years and the weighted-average interest rate on total borrowings as of December 31, 2025 is 4.9%.

Leases

Operating lease costs were $70 million, $63 million and $67 million for the year ended December 31, 2025, 2024, and 2023, respectively.

None of the Company’s lease agreements contain variable lease payments. Sublease income is immaterial and there are no sale-leaseback transactions. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Cash paid for amounts included in the measurement of operating lease liabilities was $52 million, $52 million and $56 million for the year ended December 31, 2025, 2024 and 2023, respectively. Operating lease assets obtained in exchange for new operating lease liabilities were $37 million, $25 million and $25 million for the year ended December 31, 2025, 2024 and 2023, respectively, and primarily consists of real estate operating leases. As of December 31, 2025 and 2024, the Company did not have any arrangements that met the criteria for classification as finance leases.

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Financial Instruments Financial Instruments
The Company measures fair value based on the prices that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based on a three-tier hierarchy that prioritizes the inputs used to measure fair value. These tiers include Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The following financial instruments were recorded at their estimated fair value. The recurring fair value measurement of the assets and liabilities was as follows:

Foreign Currency Risk Management

The Company uses a balance sheet risk management program to partially mitigate the exposure of net monetary assets of its subsidiaries that are denominated in a currency other than a subsidiary’s functional currency from the effects of volatility in foreign exchange. In these instances, Organon principally utilizes forward exchange contracts to partially offset the effects of exchange on exposures denominated in developed country currencies, primarily the euro, Swiss franc, and Canadian dollar. For exposures in developing country currencies, the Company enters into forward contracts to partially offset the effects of exchange on exposures when it is deemed economical to do so based on a cost-benefit analysis that considers the magnitude of the exposure, the volatility of the exchange rate and the cost of the hedging instrument.

Forward Contracts

Monetary assets and liabilities denominated in a currency other than the functional currency of a given subsidiary are remeasured at spot rates in effect on the balance sheet date with the effects of changes in spot rates reported in Exchange losses in the Consolidated Statements of Income. The forward contracts are not designated as hedges and are marked to market through Exchange losses in the Consolidated Statements of Income. Accordingly, fair value changes in the forward contracts help mitigate the changes in the value of the remeasured assets and liabilities attributable to changes in foreign currency exchange rates, except to the extent of the spot-forward differences. These differences are not significant due to the short-term nature of the contracts, which typically have average maturities at inception of less than one year. The notional amount of forward contracts was $1.7 billion and $1.4 billion as of December 31, 2025 and December 31, 2024, respectively. The cash flows and the related gains and losses from these contracts are reported as Operating activities in the Consolidated Statements of Cash Flows.

Net Investment Hedge

Euro-denominated debt instruments

Foreign exchange risk is also managed through the use of economic hedges on foreign currency balances. €717 million of the euro-denominated term loan and €1.25 billion of the 2.875% euro-denominated secured notes have been designated and are effective as a hedge of the net investment in euro-denominated subsidiaries. See Note 12 “Long-Term Debt, Short-Term
Borrowings and Leases” for additional details.

Cross-Currency Swaps

The Company entered into cross-currency swaps that mature in 2029. The Company elected to designate the fixed-for-fixed swaps as a hedge of the net investment in euro-denominated subsidiaries balance and the change in the fair value attributable to the changes in the spot rate is recorded in Other Comprehensive Income (Loss), Net of Taxes. Throughout the term of the swaps, the Company will pay a fixed interest rate of 5.8330% based on the Euro notional amount of €922 million and receive a fixed interest rate of 7.3125% based on the U.S. dollar notional amount of $1 billion. The notional amount based on the Euro leg of the cross-currency swaps has been designated and is effective as a hedge of the net investment in euro-denominated subsidiaries. The difference between the interest rate received and paid under the cross-currency swap agreements is recorded in Interest expense in the Consolidated Statements of Income. The cash flows and the related gains and losses from the periodic settlements of the cross-currency swaps are reported as Operating Activities in the Consolidated Statements of Cash Flows.

Foreign currency gain (loss) due to spot rate fluctuations on the euro-denominated debt instruments and the change in fair value of the cross-currency swaps resulting from hedge designation were included within Cumulative translation adjustment in Other comprehensive income (loss), net of taxes:

Contingent Consideration

The fair value measurement of contingent consideration arising from business combinations is determined via probability-weighted cash flows using a Monte Carlo simulation model, which are then discounted to present value. These inputs may include: (i) the estimated amount and timing of projected cash flows, (ii) the probability of the achievement of the factor(s) on which the contingency is based and (iii) the risk-adjusted discount rate used to present value the probability-weighted cash flows. Significant increases or decreases in any of those inputs in isolation could result in a significantly higher or lower fair value measurement. At December 31, 2025, the fair value measurements of acquisition-related contingent consideration were determined using discount rates ranging from 5.18% to 6.78%.

The following table presents a reconciliation of contingent consideration measured on a recurring basis using significant unobservable inputs (Level 3):

Concentrations of Credit Risk

Organon has established accounts receivable factoring agreements with financial institutions in certain countries to sell accounts receivable. Under these agreements, Organon factored $217 million and $186 million of accounts receivable as of December 31, 2025 and December 31, 2024, respectively, which reduced outstanding accounts receivable. The cash received from the financial institutions is reported within Operating Activities in the Consolidated Statements of Cash Flows. The cost of factoring such accounts receivable were not material for the year ended December 31, 2025 and 2024.

The Company monitors credit exposures through limits that were established to limit concentration with any single issuer or institution. The majority of the Company’s accounts receivable arise from product sales in the United States, Europe and China and are primarily due from drug wholesalers and retailers, hospitals, government agencies, managed healthcare providers and pharmacy benefit managers. The Company’s customers with the largest accounts receivable balances are McKesson Corporation and Cencora, Inc., which represented approximately 14% and 7%, respectively, of total gross accounts receivable at December 31, 2025. Bad debts have been minimal. The Company does not normally require collateral or other security to support credit sales.

Actuarial Assumptions

The Company reassesses its benefit plan assumptions on a regular basis. The weighted average assumptions used in determining pension plan information are as follows:
Year Ended
December 31,
($ in millions)202520242023
Net periodic benefit cost
Discount rate2.41 %2.77 %3.82 %
Expected rate of return on plan assets4.25 4.48 4.44 
Salary growth rate2.77 2.83 2.98 
Benefit obligation
Discount rate2.65 2.41 2.77 
Salary growth rate2.56 2.77 2.83 

The discount rate is evaluated on measurement dates and modified to reflect the prevailing market rate of a portfolio of high-quality, fixed-income debt instruments that would provide the future cash flows needed to pay the benefits included in the benefit obligation as they come due.

The expected rate of return represents the average rate of return to be earned on plan assets over the period the benefits included in the benefit obligation are to be paid and is determined on a plan basis. The expected rate of return for each plan is developed considering long-term historical returns data, current market conditions, and actual returns on the plan assets. Using this reference information, the long-term return expectations for each asset category and a weighted-average expected return for each plan’s target portfolio is developed according to the allocation among those investment categories. The expected portfolio performance reflects the contribution of active management as appropriate.

In accordance with the terms of the Employee Matter Agreement, prior to the Separation, Merck continued to provide service crediting to employees that transferred to Organon under Merck’s U.S. defined benefit pension plan, supplemental executive retirement, and retiree medical plans for purposes of early retirement eligibility and subsidies, as well as for certain service crediting bridges. Although Merck is responsible for providing these benefits, Organon recorded the portion of the aggregate incremental cost of providing early retirement subsidies, service crediting bridges, and retiree healthcare benefits under these programs that is attributable to future service. Accordingly, upon Separation, the Company recorded a “grow-in” provision granted to employees transferred to Organon of $50 million, which represented the future service earned with Organon for these transferred employees for the pension and other postretirement benefits. The “grow-in” provision was recorded as an asset and will be expensed over the estimated average service period of eight years since the Separation, in operating expenses. The unamortized balance of the asset is $21 million as of December 31, 2025, of which $15 million is reflected in Other Assets and $6 million is reflected in Other current assets. See Note 17 “Third-Party Arrangements” for additional details and defined terms.

Savings Plan

Organon maintains a defined contribution savings plan in the United States. The Company matches a percentage of employees’ contributions consistent with the provisions of the plan. The Company makes retirement contributions calculated based on a predetermined formula that considers years of service and the employee’s age. Total actual employer contributions to this plan in 2025, 2024 and 2023 were $39 million and $36 million and $39 million, respectively.

As of December 31, 2025 and 2024, the Company had $117 million and $187 million, respectively, in Accrued and other current liabilities of the Consolidated Balance Sheets related to annual compensation.

Under the agreement, Samsung Bioepis is responsible for preclinical and clinical development, process development and manufacturing, clinical trials and registration of product candidates, and the Company has an exclusive license for worldwide commercialization with certain geographic exceptions specified on a product-by-product basis. The Company's access rights to each product under the agreement last for 10 years from each product's launch date on a market-by-market basis. Gross profits are shared equally in all markets with the exception of certain markets in Brazil where gross profits are shared 65% to Samsung Bioepis and 35% to the Company. Since the Company is the principal on sales transactions with third parties, the Company recognizes sales, cost of sales and selling, general and administrative expenses on a gross basis. Generally, profit sharing adjustments are recorded either to Cost of sales (after commercialization) or Selling, general and administrative expenses (prior to commercialization).

Samsung Bioepis is eligible for additional payments associated with pre-specified clinical and regulatory milestones. As of December 31, 2025, there was one remaining potential future regulatory milestone payment of $25 million that remained unpaid under the agreement.

Third-Party Arrangements Third-Party Arrangements
On June 2, 2021, Organon and Merck entered into a Separation and Distribution Agreement (the “Separation and Distribution Agreement”). Pursuant to the Separation and Distribution Agreement, Merck agreed to spin off the Organon products into Organon, a new, publicly-traded company (the “Separation”).

The Separation and Distribution Agreement, contains provisions that, among other things, relate to (i) assets, liabilities and contracts to be transferred, assumed and assigned to each of Organon and Merck as part of the Separation, (ii) cross-indemnities principally designed to place financial responsibility for the obligations and liabilities of the Organon business with Organon and financial responsibility for the obligations and liabilities of Merck’s remaining business with Merck, (iii) procedures with respect to claims subject to indemnification and related matters, (iv) the allocation between Organon and Merck of rights and obligations under existing insurance policies with respect to occurrences prior to completion of the Distribution, as well as the right to proceeds and the obligation to incur certain deductibles under certain insurance policies, and (v) procedures governing Organon’s and Merck’s obligations and allocations of liabilities with respect to ongoing litigation matters that may implicate each of Merck’s business and Organon’s business.

Agreements that Organon entered into with Merck that govern aspects of Organon’s relationship with Merck following the Separation include:
Interim Operating Agreements - Merck and Organon entered into a series of interim operating model (“IOM”) agreements, pursuant to which Merck and certain of its affiliates that held licenses, permits and other rights in connection with marketing, import and/or distribution of Organon products in various jurisdictions prior to the Separation, continue to market, import and distribute such products until such time as the relevant licenses and permits are transferred to Organon or its affiliates, while permitting Organon (or Merck, as applicable) to recognize revenue relating to the sale of its respective products, to the extent practicable. Under such IOM agreements and in accordance with the Separation and Distribution Agreement, the relevant Merck entity will continue operations in the affected market on behalf of Organon, with Organon receiving all of the economic benefits and burdens of such activities. Organon began receiving these economic benefits as of June 2, 2021. Based on the terms of the IOM agreements, the Company determined it is the Principal under these arrangements. Organon holds all risks and rewards of ownership inclusive of risk of loss, market risk and benefits related to the inventory. Additionally, Organon has control in pricing, has the ability to direct Merck regarding decisions over inventory, and is responsible for all credit and collections risks and losses associated with the related receivables. As such, Organon recognizes these sales on a gross basis. As of December 31, 2025, only one jurisdiction remains under an IOM agreement.
Manufacturing and Supply Agreements - Merck and Organon and/or their applicable affiliates entered into a number of manufacturing and supply agreements pursuant to which the relevant Merck entity (a) manufactures and supplies certain active pharmaceutical ingredients for the relevant Organon entity, (b) toll manufactures and supplies certain formulated pharmaceutical products for such Organon entity, and (c) packages and labels certain finished pharmaceutical products for such Organon entity. Similarly, the relevant Organon entity (a) manufactures and supplies certain formulated pharmaceutical products for the relevant Merck entity, and (b) packages and labels certain finished pharmaceutical products for such Merck entity. Certain of these Manufacturing and Supply Agreements have terminated or expired, including agreements that no are longer required following Organon’s acquisition of the Oss Biotech manufacturing facility in the Netherlands from Merck in July 2025.
Tax Matters Agreement - The TMA allocates responsibility for all U.S. federal income, state and foreign income, franchise, capital gain, withholding and similar taxes, as well as all non-income taxes. The TMA also provides for cooperation between Merck and Organon with respect to tax matters, the exchange of information and the retention of records that may affect the tax liabilities of the parties to the TMA. Merck generally is responsible for any income taxes reportable on an originally filed consolidated, combined or unitary return that includes Merck or any of its subsidiaries (and Organon and/or any of its subsidiaries) for any periods or portions thereof ending on or prior to the Distribution. Organon generally is responsible for any income taxes that are reportable on originally filed returns that include only Organon and/or any of its subsidiaries, for all tax periods. Additionally, as a general matter, Merck is responsible for certain income and non-income taxes imposed as the direct result of the Separation or of an internal separation transaction. Organon is responsible for certain taxes that exclusively relate to Organon’s business and for taxes resulting from any breach of certain representations or covenants that Organon made in the TMA. Certain amounts are estimates and subject to possible adjustment in future periods.
Other agreements that Organon entered into with Merck include the Intellectual Property License Agreements and Regulatory Agreements.

Commitments and Contingencies Disclosure [Abstract]  
Contingencies Contingencies
Organon is involved in various claims and legal proceedings of a nature considered normal to its business, including product liability, intellectual property, and commercial litigation, as well as certain additional matters including governmental and environmental matters.

Organon records accruals for contingencies when it is probable that a liability has been incurred and the amount can be reasonably estimated. These accruals are adjusted periodically as assessments change or additional information becomes available. Individually significant contingent losses are accrued when probable and reasonably estimable. Legal defense costs expected to be incurred in connection with a loss contingency are accrued when probable and reasonably estimable.

Given the nature of the litigation discussed in this note and the complexities involved in these matters, Organon is unable to reasonably estimate a possible loss or range of possible loss for such matters until Organon knows, among other factors, (i) which claims, if any, will survive dispositive motion practice, (ii) the extent of the claims, including the size of any potential class, particularly when damages are not specified or are indeterminate, (iii) how the discovery process will affect the litigation, (iv) the settlement posture of the other parties to the litigation, and (v) any other factors that may have a material effect on the litigation.

Organon’s decision to obtain insurance coverage is dependent on market conditions, including cost and availability, existing at the time such decisions are made. Organon has evaluated its risks and has determined that the cost of obtaining product liability insurance outweighs the likely benefits of available coverage and, as such, has no insurance for most product liabilities.

Reference is made below to certain litigation in which Merck, but not Organon, is named as a defendant. Pursuant to the Separation and Distribution Agreement, Organon is required to indemnify Merck for liabilities relating to, arising from, or resulting from such litigation.

Product Liability Litigation

Fosamax

Merck is a defendant in product liability lawsuits in the United States involving Fosamax® (alendronate sodium) (the “Fosamax Litigation”). As of December 31, 2025, the Fosamax Litigation comprises approximately 527 cases in Federal court, approximately 1,520 cases in New Jersey state court, one case in Pennsylvania state court and approximately 218 cases in California state court. Plaintiffs in the vast majority of these cases generally allege that they sustained femur fractures and/or other bone injuries (“Femur Fractures”) in association with the use of Fosamax.

All federal cases involving allegations of femur fractures have been transferred to a multidistrict litigation in the U.S. District Court for the District of New Jersey (“Femur Fracture MDL”). In the only bellwether case tried to date in the Femur Fracture
MDL, Glynn v. Merck, the jury returned a verdict in Merck’s favor. In addition, in June 2013, the Femur Fracture MDL court granted Merck’s motion for judgment as a matter of law in the Glynn case and held that the plaintiff’s failure to warn claim was preempted by federal law. The Femur Fracture MDL court then dismissed with prejudice approximately 650 cases on these same preemption grounds. Following a series of appeals, including a U.S. Supreme Court (“Supreme Court”) decision in 2019, the U.S. Court of Appeals for the Third Circuit (“Third Circuit”) ruled in September 2024 that plaintiffs’ failure-to-warn claims are not preempted by federal law. Consequently, approximately 844 cases are now before the Femur Fracture MDL court for further litigation. On March 10, 2025, Organon filed a writ of certiorari to the Supreme Court seeking review of the Third Circuit decision. On June 16, 2025, the Supreme Court denied the writ.

In New Jersey state court, the cases have been consolidated before a single judge in Middlesex County. On July 28, 2025, the Company signed a Master Settlement Agreement with the New Jersey state and federal plaintiffs’ lawyers who represent eligible clients (“NJ MSA Attorneys”), which provides that in exchange for a settlement amount (which is confidential, but non-material), at least 95% of the NJ MSA Attorneys’ eligible clients will release the Company and Merck from any liability related to their filed claims.

In California state court, the cases have been consolidated before a single judge in Orange County, California. In the only bellwether case tried to date in California, Galper v. Merck, the jury returned a verdict in Merck’s favor.

Nexplanon/Implanon

Merck is a defendant in lawsuits brought by individuals relating to the use of Nexplanon and Implanon™ (etonogestrel implant). There are two filed product liability actions involving Implanon, both of which are pending in the Northern District of Ohio as well as 56 unfiled cases involving Implanon alleging similar injuries, all of which have been tolled under a written tolling agreement. There is one matter involving Nexplanon pending in state court in California. As of December 31, 2025, Merck had 17 cases pending outside the United States, of which seven relate to Implanon and eleven relate to Nexplanon.

Securities and Stockholder Derivative Litigation

On May 27, 2025, a stockholder filed a lawsuit against the Company and certain of its officers on behalf of a putative class of stockholders who purchased or otherwise acquired shares between October 31, 2024 and April 30, 2025. A separate stockholder suit was filed on July 8, 2025 on behalf of a putative class of stockholders who purchased shares between November 3, 2022 and April 30, 2025. Plaintiffs in each of these cases allege that defendants made materially false and misleading statements regarding the Company’s capital allocation strategy, including through the use of quarterly dividends, and its debt reduction strategy. Between July 22, 2025 and July 25, 2025, pursuant to the Private Securities Litigation Reform Act, six parties filed motions for consolidation of the related actions and to be appointed lead plaintiff. Five of those parties have since withdrawn their motions or filed notices stating that they do not oppose the motions for consolidation. The same allegations at issue in the securities lawsuits also form the basis for two stockholder derivative lawsuits filed against the Company, and certain of its officers and directors. The stockholder derivative suits further allege that the individual defendants breached their fiduciary duties based on the purportedly materially false and misleading statements that were made. On July 7, 2025, the court consolidated each of the stockholder derivative lawsuits. Subsequently, on September 8, 2025, the court entered an order deferring the derivative action until all motions to dismiss filed in the securities lawsuits are fully and finally resolved. Each of the foregoing actions was filed in the U.S. District Court for the District of New Jersey and each seek unspecified monetary damages and other relief.

Governmental Proceedings

From time to time, Organon and its subsidiaries receive inquiries and may be the subject of preliminary investigation activities from competitors and/or other governmental authorities, including in markets outside the United States. These authorities may include regulators, administrative authorities, and law enforcement and other similar officials, and these preliminary investigation activities may include site visits, formal or informal requests or demands for documents or materials, inquiries or interviews and similar matters. Certain of these preliminary inquiries or activities may lead to the commencement of formal proceedings. Should those proceedings be determined adversely to Organon, monetary fines and/or remedial undertakings may be required. Subject to certain exceptions specified in the Separation and Distribution Agreement, Organon assumed liability for all pending and threatened legal matters related to products transferred from Merck to Organon in connection with the spinoff, including competition investigations resulting from enforcement activity concerning Merck’s conduct involving Organon’s products. Organon could be obligated to indemnify Merck for fines or penalties, or a portion thereof, resulting from such investigations.

On October 26, 2025, Organon made a voluntary self-disclosure to the U.S. Securities and Exchange Commission (the “SEC”)
to advise it of an investigation conducted by the Audit Committee of the Company’s Board of Directors (the “Audit Committee”) regarding the Company’s Nexplanon sales to certain wholesalers in the United States. The SEC subsequently opened an investigation into these matters, and the Company intends to cooperate with any inquiries from the SEC or any other regulatory authorities. The Company cannot guarantee that it (or its directors or officers) will not be subject to future inquiries, investigations, claims, actions, or proceedings, nor can it predict the outcome of any of the foregoing; however, regardless of outcome, any inquiries, investigations, claims, actions, or proceedings relating to the Audit Committee’s investigation would likely consume a significant amount of Company resources and result in considerable legal and accounting costs.

Patent Litigation

From time to time, generic manufacturers of pharmaceutical products file Abbreviated New Drug Applications with the FDA seeking to market generic forms of Organon’s products prior to the expiration of relevant patents owned by Organon. To protect its patent rights, Organon may file patent infringement lawsuits against such generic companies. Similar lawsuits defending Organon’s patent rights may exist in other countries. Organon intends to vigorously defend its patents, which it believes are valid, against infringement by companies attempting to market products prior to the expiration of such patents. As with any litigation, there can be no assurance of the outcomes, which, if adverse, could result in significantly shortened periods of exclusivity for these products, potential payment of damages and legal fees, and, with respect to products acquired through acquisitions, potentially significant intangible asset impairment charges.

Nexplanon

On February 24, 2025, Organon received a Paragraph IV Certification Letter notifying the Company that Xiromed Pharma Espana, S.L. (“Xiromed”) filed an abbreviated new drug application (“ANDA”) to the FDA seeking approval to market a generic version of Nexplanon in the United States prior to the expiration of U.S. Patent Nos. 8,722,037 (The “‘037 patent”) and 9,757,552 (the “‘552 patent”), in 2027 and 2030, respectively. On April 2, 2025, the Company sued Xiromed in the U.S. District Court for the District of New Jersey asserting that the filing of the ANDA infringed the ‘037 patent and ‘552 patent and triggering a stay of regulatory approval of Xiromed’s ANDA for up to 30 months.

Other Matters

In addition to the matters described above, there are various other pending legal proceedings involving Organon, principally product liability and intellectual property lawsuits. While it is not feasible to predict the outcome of such proceedings, in the opinion of Organon as of December 31, 2025, either the likelihood of loss is remote or any reasonably possible loss associated with the resolution of such proceedings is not expected to be material to Organon’s financial condition, results of operations or cash flows either individually or in the aggregate.

Legal Defense Reserves

Legal defense costs expected to be incurred in connection with a loss contingency are accrued when probable and reasonably estimable. Some of the significant factors considered in the review of these legal defense reserves are as follows: the actual costs incurred by Organon; the development of Organon’s legal defense strategy and structure in light of the scope of its litigation; the number of cases being brought against Organon; and the costs and outcomes of completed trials and the most current information regarding anticipated timing, progression, and related costs of pre-trial activities and trials in the associated litigation. The legal defense reserve as of December 31, 2025 and December 31, 2024 was $10 million and $7 million, respectively, and represented Organon’s best estimate of the minimum amount of defense costs to be incurred in connection with its outstanding litigation; however, events such as additional trials and other events that could arise in the course of its litigation could affect the ultimate amount of legal defense costs to be incurred by Organon. Organon will continue to monitor its legal defense costs and review the adequacy of the associated reserves and may determine to increase the reserves at any time in the future if, based upon the factors set forth above, it believes it would be appropriate to do so.
Environmental Matters

In management’s opinion, the liabilities for all environmental matters that are probable and reasonably estimable have been accrued and totaled $16 million for both December 31, 2025 and 2024. These liabilities are undiscounted, do not consider potential recoveries from other parties and will be paid out over the periods of remediation for the applicable sites, which are expected to occur primarily over the next 12 years. It is not possible to predict with certainty the outcome of these matters, or the ultimate costs of remediation. Management also does not believe that these expenditures should result in a material adverse effect on the Company’s financial condition, results of operations or liquidity for any period presented.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Cybersecurity Risk Management and Strategy. We depend on sophisticated software applications, complex information technology systems, computing infrastructure and cloud service providers (collectively, “Information Systems”) to conduct critical operations. Certain of these systems are managed, hosted, provided, or used by third parties.

We implement processes for the assessment, identification, and management of material risks from cybersecurity threats; however, disruption, degradation, destruction or manipulation of our Information Systems through intentional or accidental means by our employees, third parties with authorized access or cyber threat actors could adversely affect key business processes. The size and complexity of our Information Systems, and those of our third-party providers with whom we contract, make such systems potentially vulnerable to service interruptions. In addition, we and our third-party providers have experienced and expect to continue to experience phishing attempts, scanning attempts of our network, and other attempts of unauthorized access to our computers, digital systems, networks, or devices. Such attacks are increasingly sophisticated and are made by groups and individuals with a wide range of motives and expertise, including state and quasi-state actors, criminal groups, “hackers” and others. These attacks could lead to loss of confidentiality, integrity and/or availability of our data and Information Systems.

In the ordinary course of business, we and our third-party providers collect, store and transmit large amounts of confidential information (including trade secrets or other intellectual property, proprietary business information and personal information), and we must do so in a secure manner to maintain the confidentiality and integrity of such confidential information. While we have controls to protect such information, and aim to ensure that the third-party providers on which we rely have taken steps to protect such information, such controls may not be adequate. A breach of our Information Systems or those of our third-party providers, such as cloud-based systems, or the accidental loss, inadvertent disclosure, unapproved dissemination, misappropriation or misuse of trade secrets, proprietary information, or other confidential information, whether as a result of theft, hacking, fraud, trickery, other forms of deception, or any other cause, could enable others to produce competing products, use our proprietary technology or information, and/or adversely affect our business position. Further, any such interruption, security breach, or loss, misappropriation, and/or unauthorized access, use or disclosure of confidential information, including personal information regarding our consumers and employees, or the modification of critical data, could result in financial, legal, business, and reputational harm to us, including loss of revenue, loss of critical or sensitive information from our or our third-party providers' databases or Information Systems, and substantial remediation and recovery costs. Although such risks have not materially affected us, including our business strategy, results of operations or financial condition, to date, we have, from time to time, experienced threats to our data and systems, including malware and computer virus attacks.
We use information security and data privacy programs and practices designed to foster the safe, secure, and responsible use of the information and data our stakeholders entrust to us. We work with our customers, governments, policymakers, and others to help develop and implement standards for safe and secure transactions, as well as privacy-centric data practices.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Revenue Recognition Recognition of revenue requires evidence of a contract, probable collection of sales proceeds and completion of substantially all performance obligations. The Company acts as the principal in its customer arrangements and therefore records revenue on a gross basis. The majority of the Company’s contracts have a single performance obligation — the promise to transfer goods. Shipping is considered immaterial in the context of the overall customer arrangement and damages or loss of goods in transit are rare. Therefore, shipping is not deemed a separately recognized performance obligation.
Revenues from sales of products, including tenders, are recognized at a point in time when control of the goods is transferred to the customer, which the Company has determined is when title and risks and rewards of ownership transfer to the customer and the Company is entitled to payment.

The nature of the Company’s business gives rise to several types of variable consideration including discounts and returns, which are estimated at the time of sale generally using the expected value method, although the most likely amount method is used for prompt pay discounts.

In the United States, sales discounts are issued to customers at the point-of-sale, through an intermediary wholesaler (known as chargebacks), or in the form of rebates. Additionally, sales are generally made with a limited right of return under certain
conditions. Revenues are recorded net of provisions for sales discounts and returns, which are established at the time of sale. In addition, revenues are recorded net of time value of money discounts if collection of accounts receivable is expected to be in excess of one year.

Chargebacks are discounts that occur when a contracted customer purchases through an intermediary wholesaler. The contracted customer generally purchases product from the wholesaler at its contracted price plus a mark-up. The wholesaler, in turn, charges the Company back for the difference between the price initially paid by the wholesaler and the contract price paid to the wholesaler by the customer. The Company estimates the provision for chargebacks based on expected sell-through levels by the Company’s wholesale customers to contracted customers, as well as estimated wholesaler inventory levels. Rebates are amounts owed based upon definitive contractual agreements or legal requirements with private sector, (Managed Care), and public sector (Medicaid and Medicare Part D) benefit providers, after the final dispensing of the product by a pharmacy to a benefit plan participant. The provision for rebates is based on expected patient usage, as well as inventory levels in the distribution channel to determine the contractual obligation to the benefit providers. The Company uses historical customer segment utilization mix, sales, changes to product mix and price, inventory levels in the distribution channel, government pricing calculations and prior payment history to estimate the expected provision.

The Company continually monitors the provision for aggregate customer discounts. There were no material adjustments to estimates associated with the aggregate customer discount provision in 2025, 2024, or 2023.

Summarized information about changes in the aggregate customer discount accrual related to sales in the United States is as follows:

The accrued balances relative to the provisions for chargebacks and rebates in the United States included in Accounts receivable and Accrued and other current liabilities were $111 million and $412 million, respectively, at December 31, 2025 and $100 million and $380 million, respectively, at December 31, 2024.

Outside of the United States, variable consideration in the form of discounts and rebates is a combination of commercially-driven discounts in highly competitive product classes, discounts required to gain or maintain reimbursement, or legislatively mandated rebates. The accrued balances relative to the provision for chargebacks and rebates, based on the terms and nature of the rebate, are included in Accounts receivable and Accrued and other current liabilities. Rebates may also be required based on specific product sales thresholds. The Company applies an estimated factor against its actual invoiced sales to represent the expected level of future discount or rebate obligations associated with the sale. At December 31, 2025 and 2024, the accrued balances related to the provision for rebates and discounts included in other current liabilities were approximately $180 million and $155 million, respectively.

The Company maintains a returns policy that allows customers in certain countries to return product within a specified period prior to and subsequent to the expiration date (generally, three to six months before and 12 months after product expiration). The estimate of the provision for returns is based upon historical experience with actual returns and consideration of other relevant factors.

The Company’s payment terms are typically 30 days to 90 days, although certain markets have longer payment terms. See Note 5 “Product and Geographic Information” for disaggregated revenue disclosures.
Cash Equivalents Cash equivalents are comprised of certain highly liquid investments with original maturities of three months or less.
Inventories Inventories are valued at the lower of cost or net realizable value. The cost of a substantial majority of U.S. inventories is determined using the last-in, first-out (“LIFO”) method for both financial reporting and tax purposes. The cost of all other inventories is determined using the first-in, first-out (“FIFO”) method.
Value Added Tax The Company’s purchases, sales and intercompany transfers of goods are subject to value added tax (“VAT”) and VAT receivables are recognized for amounts that represent credits against future VAT obligations. VAT receivables included in
Depreciation Depreciation is provided over the estimated useful lives of the assets, principally using the straight-line method. The estimated useful lives primarily range from 25 to 40 years for buildings, and from 3 to 15 years for machinery, equipment and office furnishings. Depreciation expense was $156 million in 2025, $132 million in 2024, and $120 million in 2023. Repairs and maintenance costs are expensed as incurred as they do not extend the economic life of an asset.
Advertising and Promotion Cost Advertising and promotion costs are expensed as incurred and included in Selling, general and administrative expenses.
Goodwill Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses acquired. Goodwill is evaluated for impairment each year in the fourth quarter, or more frequently if impairment indicators exist, by first assessing qualitative factors to determine whether it is more likely than not that fair value is less than carrying value. If the Company concludes it is more likely than not that fair value is less than carrying value, a quantitative fair value test is performed. If carrying value is greater than fair value, a goodwill impairment charge will be recorded for the difference (up to the carrying value of goodwill).
The Company estimates the fair value of a reporting unit using a discounted cash flow model which relies on projected cash flows and market assumptions. Key assumptions used in projected cash flows include projected revenue growth rates, cost of sales, selling, general and administrative expenses, terminal growth rates, and discount rates. These assumptions require significant judgment and are based on best estimates of future economic and market conditions. A significant decline in forecasted performance, whether due to external economic factors or internal operational challenges, could result in the fair value of either the U.S. or International reporting unit falling below its carrying amount. In such cases, the Company would be required to recognize a non-cash impairment charge, which could materially impact our financial condition and results of operations. Additionally, the Company may be required to record impairment charges on goodwill related to a reporting unit if adverse macroeconomic or geopolitical developments materially affect our business outlook. These developments may include, but are not limited to, the implementation of tariffs, changes in trade policies, inflationary pressures, supply chain disruptions, or regulatory changes that reduce forecasts or increase operating costs. See Note 11 “Intangibles and Goodwill” for additional details.
Acquired Intangibles ntangibles include products and product rights and licenses, which are initially recorded at fair value, assigned an estimated useful life, and amortized on a straight-line basis over their estimated useful lives. Licenses include milestone payments made to collaborative partners upon or subsequent to regulatory approval. The estimated useful lives of intangibles range from 5 to 15 years. The Company periodically evaluates whether current facts or circumstances indicate that the carrying values of its intangibles may not be recoverable. If such circumstances are determined to exist, an estimate of the undiscounted future cash flows of these assets, or appropriate asset groupings, is compared to the carrying value to determine whether an impairment exists. If the asset is determined to be impaired, the loss is measured based on the difference between the carrying value of the intangible asset and its fair value, which is determined based on the net present value of estimated future cash flows. See Note 11 “Intangibles and Goodwill” for additional details.
Acquired In-Process Research and Development (“IPR&D”) and Acquired in-process research and development and milestones IPR&D that the Company acquires in conjunction with the acquisition of a business represents the fair value assigned to incomplete research projects which, at the time of acquisition, have not reached technological feasibility. The amounts are capitalized and are accounted for as indefinite-lived intangible assets, subject to impairment testing until completion or abandonment of the projects. Upon successful completion of each project, Organon will make a determination as to the then-useful life of the intangible asset, generally determined by the period in which the substantial majority of the cash flows are expected to be generated, and begin amortization. The Company evaluates IPR&D for impairment as of October 1 each year, or more frequently if impairment indicators exist and it is more likely than not that the fair value is less than its carrying amount, by performing a quantitative test that compares the fair value of the IPR&D intangible asset with its carrying value. If the fair value is less than the carrying amount, an impairment loss is recognized in operating results. See Note 11 “Intangibles and Goodwill” for additional details.Acquired IPR&D and milestones includes upfront and milestone payments, related to asset acquisitions, licensing or collaborative arrangements that are not considered an acquisition of a business and involve clinical development programs that have not yet received regulatory approval
Contingent Consideration For transactions accounted for as a business acquisition, contingent consideration liabilities are recognized at the estimated fair value on the acquisition date. Subsequent changes to the fair value of contingent consideration liabilities are recognized in Other expense, net in the Consolidated Statements of Income. Contingent consideration payments made or received soon after the acquisition date are classified as Investing activities in the Consolidated Statements of Cash Flows. Contingent consideration payments not made or received soon after the acquisition date that are related to the acquisition date fair value are reported as Financing activities in the Consolidated Statements of Cash Flows, and amounts paid or received in excess of the original acquisition date fair value are reported as Operating activities in the Consolidated Statements of Cash Flows. For transactions accounted for as an asset acquisition, contingent consideration liabilities that are payable prior to regulatory approval are recognized in Acquired in-process research and development and milestones in the Consolidated Statements of Income when achievement of the milestone is deemed probable. Contingent consideration liabilities that are payable on or after regulatory approval are capitalized as intangible assets when the payments have become probable and amortized to Cost of sales over the remaining useful life of the related intangible assets.
Research and Development Research and development costs associated with clinical development programs that have not yet received regulatory approval are expensed as incurred
Foreign Currency Transaction and Translation
Foreign Currency Transaction and Translation — Transactions denominated in a currency other than the entity's functional currency is considered a foreign currency transaction. Foreign currency transactions may produce cash, receivables or payables which are fixed in terms of the amount of foreign currency to be received/paid. A change in exchange rate before settlement between the functional currency and the currency in which the transaction is denominated is included in net income in the period of exchange rate change as Exchange losses. The net assets of international operations where the local currencies have been determined to be the functional currencies are translated into U.S. dollars using current exchange rates. The U.S. dollar effects that arise from translating the net assets of these subsidiaries at changing rates are recorded in the foreign currency translation account, which is included in Accumulated other comprehensive loss and reflected as a separate component of equity. For those operations that operate in highly inflationary economies and for those operations where the U.S. dollar has been determined to be the functional currency, non-monetary foreign currency assets and liabilities are translated using historical rates, while monetary assets and liabilities are translated at current rates, with the U.S. dollar effects of rate changes included in Exchange losses.
Stock-Based Compensation Effective June 3, 2021, Organon established the 2021 Incentive Stock Plan (the “Plan”). A total of 42.8 million shares of Common Stock are authorized under the Plan, reflecting an increase of 7.8 million shares approved in the Company’s 2025 Proxy Statement. The plan provides for the grant of various types of awards, including restricted stock unit awards, stock appreciation rights, stock options, performance-based awards and cash awards. Under the Plan, the exercise price of awards, if any, is set on the grant date and may not be less than the fair market value per share on that date. The Company measures stock-based compensation for equity awards at fair value on the date of grant and records stock-based compensation as a charge to earnings net of the estimated impact of forfeited awards. Accordingly, the Company recognizes stock-based compensation cost only for those stock-based awards that are estimated to ultimately vest over their requisite service period, based on the vesting provisions of the individual grants. The cumulative effect on current and prior periods of a change in the estimated forfeiture rate is recognized as compensation cost in earnings in the period of the change. See Note 6 “Stock-Based Compensation Plans” for additional details.
Pension and Other Postretirement Benefit Plans For certain defined benefit plans, the over funded or underfunded status of the plan was recognized as an asset or liability on the consolidated balance sheet. Organon sponsors certain non-U.S. defined benefit pension plans. See Note 14 “Pension and Other Postretirement Benefit Plans” for additional details
Restructuring Costs Costs associated with exit or disposal activities are recognized in the period in which they are incurred. Costs for one-time termination benefits in which the employee is required to render service until termination in order to receive the benefits are recognized ratably over the future service period. In accordance with existing benefit arrangements, future employee termination costs to be incurred in conjunction with involuntary separations are accrued when such separations are probable and estimable.
Contingencies and Legal Defense Costs The Company records accruals for contingencies and legal defense costs expected to be incurred in connection with a loss contingency when it is probable that a liability has been incurred and the amount can be reasonably estimated.
Taxes on Income Deferred taxes are recognized for the future tax effects of temporary differences between financial and income tax reporting based on enacted tax laws and rates. The Company establishes valuation allowances for its deferred tax assets when the amount of expected future income is not likely to support the use of the deduction or credit. The Company assesses all available evidence to estimate whether a valuation allowance should be recorded against existing deferred tax assets. The amounts of the deferred tax asset considered realizable, however, could be adjusted in future periods if estimates of future income are reduced or increased.
The Company evaluates tax positions to determine whether the benefits of tax positions are more likely than not of being sustained upon audit based on the technical merits of the tax position. For tax positions that are more likely than not of being sustained upon audit, the Company recognizes the largest amount of the benefit that is greater than 50% likely of being realized upon ultimate settlement in the Consolidated Financial Statements. For tax positions that are not more likely than not of being sustained upon audit, the Company does not recognize any portion of the benefit in the Consolidated Financial Statements.

The Company recognizes interest and penalties associated with uncertain tax positions as a component of Taxes on Income in the Consolidated Statement of Income. The Company accounts for the tax effects of the tax on global intangible low-taxed income of certain foreign subsidiaries in the income tax provision in the period the tax arises. The Company and Merck entered into the Tax Matters Agreement in connection with the Separation. See Note 17 “Third-Party Arrangements” for additional details and defined terms.
Leases The Company has operating leases primarily for real estate. The Company determines if an arrangement is a lease at inception. When evaluating contracts for embedded leases, the Company exercises judgment to determine if there is an explicit or implicit identified asset in the contract and if the Company controls the use of that asset. Embedded leases are immaterial. The lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company has made an accounting policy election not to record short-term leases (leases with an initial term of 12 months or less) on the balance sheet. Lease expense associated with short term leases is not material for all periods presented.
Lease expense for operating lease payments is recognized on a straight-line basis over the term of the lease. Operating lease assets and liabilities are recognized based on the present value of lease payments over the lease term. Since most of the Company’s leases do not have a readily determinable implicit discount rate, the Company uses its incremental borrowing rate to calculate the present value of lease payments. On a quarterly basis, an updated incremental borrowing rate is determined based on the weighted average remaining lease term of each asset class and the Company’s pretax cost of debt for that same term. The updated rates for each asset class are applied prospectively to new leases. The Company does not separate lease components (e.g., payments for rent) from non-lease components (e.g., common-area maintenance costs) in the event that the agreement contains both. The Company includes both the lease and fixed non-lease components for purposes of calculating the lease liability and the related right-of-use asset. See Note 12 “Long-Term Debt, Short Term Borrowings and Leases” for additional details.
Principles of Consolidation The consolidated financial statements include the accounts of the Company and all of its subsidiaries. All intercompany transactions and accounts have been eliminated.
Use of Estimates The presentation of these Consolidated Financial Statements and accompanying notes in conformity with U.S. GAAP require management to make estimates and assumptions that affect the amounts reported. Estimates are used in determining such items as provisions for sales discounts and returns, depreciable and amortizable lives, recoverability of inventories, amounts recorded for contingencies, environmental liabilities, pension and other postretirement benefit plan assumptions, stock-based compensation assumptions, restructuring costs, impairments of long-lived or indefinite-lived assets (including intangible assets and goodwill), investments, and taxes on income. Additionally, estimates are used in acquisitions, including initial fair value determinations of assets and liabilities (primarily IPR&D, intangible assets and contingent consideration), as well as subsequent fair value measurements.
Segment information The Company operates as one operating segment comprised of two reporting units: U.S. and International. Organon is engaged in developing and delivering innovative health solutions through its portfolio of prescription therapies within women's health and general medicines. The Company’s chief operating decision‑maker (the “CODM”) is the Interim Chief Executive Officer. The CODM assesses performance and decides how to allocate resources for our one operating segment based on consolidated net income that is reported on the consolidated statements of income. The Company has also evaluated the significant segment expenses incurred by our single segment and regularly provided to the CODM. The significant segment expenses provided to the CODM are consistent with those reported on the Consolidated Statements of Income and include cost of sales, selling, general and administrative, research and development, interest expense and income
taxes. The CODM uses these metrics to make key operating decisions such as: approving a new product launch strategy, making significant capital expenditures, approving the design of key commercialization strategies, decisions about key personnel, and approving annual operating and capital budgets. Our CODM considers budget-to-actual variances and year over year performance when making decisions supporting capital resource allocation. The Company manages assets on a consolidated basis as reported on the consolidated balance sheets.
