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. 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.

Basis of Presentation Basis of Presentation
The accompanying unaudited financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and disclosures required by GAAP for complete consolidated financial statements are not included herein. The results of operations for any interim period are not necessarily indicative of the results of operations for the full year. In the Company’s opinion, all adjustments necessary for a fair statement of these interim statements have been included and are of a normal and recurring nature. All intercompany transactions and accounts within Organon have been eliminated. These interim statements should be read in conjunction with the audited financial statements and notes thereto included in Organon’s Annual Report on Form 10-K for the year ended December 31, 2025.

Use of Estimates

The presentation of these Condensed Consolidated Financial Statements and accompanying notes in conformity with GAAP require management to make estimates and assumptions that affect the amounts reported, as further described in the Annual Report on Form 10-K for the year ended December 31, 2025. Accordingly, actual results could differ materially from management’s estimates and assumptions.

Among other things, the ASU adds the scope exception from derivative accounting for contracts that are not exchange-traded and having features based on operations or activities specific to one of the parties involved, reducing complexity and diversity in practice. The amendments in this ASU are effective for annual periods beginning on January 1, 2027, and should be applied on a prospective basis, with the option to apply the amendments on a modified retrospective basis; early adoption is permitted. The Company is currently assessing the impact of this ASU on its consolidated financial statements and related disclosures.

The amendments modernize the accounting for internal-use software to better reflect contemporary development practices, such as agile and iterative methodologies. Key changes include revised cost capitalization thresholds, enhanced guidance for assessing development uncertainty, and new disclosure requirements intended to improve transparency and consistency across entities. The amendments in this ASU are effective for annual periods beginning on January 1, 2028 and interim reporting periods within those periods, and may be applied either prospectively, retrospectively or on a modified retrospective basis; early adoption is permitted. The Company is currently assessing the impact of this ASU on its consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures, Additionally, in January 2025, the FASB issued ASU 2025-01 to clarify the effective date of ASU 2024-03.

This guidance is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. This guidance should be applied either prospectively to financial statements issued for reporting periods after the effective date or retrospectively to any or all prior periods presented in the consolidated financial statements. This ASU will have no impact on the Company’s consolidated financial condition or results of operations. The Company is currently evaluating the effects of this guidance on its related disclosures.

Acquisitions and Licensing Arrangements Acquisitions and Licensing Arrangements
Shanghai Henlius Biotech, Inc. (“Henlius”)

In the first quarter of 2026, in anticipation of the expected launch of HLX-11 in the United States, the Company entered into an agreement with Henlius that amended the terms of the existing license agreement to modify the previous commercial milestone payments. Under the amended agreement, the Company will make payments of $17 million total, with $10 million payable in December 2026, and $7 million, payable in February 2028. The Company capitalized the $17 million as an intangible asset.

In April 2026, the European Commission granted marketing authorization for Poherdy® (pertuzumab) 420 mg/14 mL injection for intravenous use, the first and only approved biosimilar to Perjeta (pertuzumab) in Europe, for all indications of the product.

Sebela Pharmaceuticals (“Sebela”)

On February 19, 2026, Organon entered into an exclusive license agreement with Sebela for the global rights to Miudella®2, a hormone-free copper intrauterine device (“IUD”) that was approved by the FDA on February 24, 2025. Under the terms of the agreement, Organon will pay $27.5 million at closing, with potential sales-based milestone payments of up to $505 million, as well as tiered double-digit royalties based on net sales. The transaction closing is subject to regulatory approvals, FDA approval of alternate supply chain entities for Miudella and other customary closing conditions. There can be no assurance that such regulatory approvals and other closing conditions will be received or satisfied.

Laborie Medical Technologies Corporation (“Laborie”)

In January 2026, the Company divested the Jada System to Laborie for an aggregate payment of up to $465 million, comprised of consideration of $440 million, subject to certain customary closing adjustments, including inventory value, plus potential contingent consideration payments of up to $25 million based on the achievement of certain 2026 net sales targets. Approximately 100 employees transferred to Laborie as part of this transaction.
Upon the closing of the divestiture, the Company recognized a net gain on the sale of the Jada System of $81 million recognized in Other (income) expense, net in the Condensed Consolidated Statement of Income as of March 31, 2026.

As part of the divestiture of the Jada System in January 2026, the Company is eligible to receive potential contingent consideration of up to $25 million based on the achievement of certain net sales targets for the Jada System during 2026. This contingent consideration is recorded as a financial asset at fair value. The fair value of the contingent consideration was estimated using the projected future net sales of the Jada System and the probability of various achievement scenarios for the sales targets. See Note 11. “Financial Instruments” for further information.

In connection with the Jada divestiture, certain related assets and liabilities met the criteria for held for sale classification as of December 31, 2025. The disposal group is measured at the lower of carrying amount or fair value less cost to sell. No impairment was recognized.

During the first quarter of 2026, the Company implemented restructuring initiatives that will result in an approximate 3% headcount reduction, to streamline and optimize the Company's research and development and manufacturing operations, focusing on enhancing efficiency and aligning resources with strategic priorities. The Restructuring costs primarily consist of employee termination benefits and other associated expenses.

During the first quarter of 2025, the Company implemented 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.

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

Taxes on Income Taxes on Income
The effective income tax rates were 31.4% and 13.4% for the three months ended March 31, 2026 and 2025, 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. Also included in the first quarter tax rate is the beneficial impact of the sale of the Jada System. There was a favorable impact to the 2025 year-to-date effective tax rate driven by a tax amortization benefit.

On July 4, 2025, U.S. House Resolution 1, referred to as the One Big Beautiful Bill Act (“OBBBA”), was signed into law. The OBBBA includes significant corporate tax provisions such as modifications to interest deductibility, the option to fully expense U.S.-based R&D costs, and changes to the taxation of foreign earnings. For 2026 and beyond, the impacts of the OBBBA are reflected in the Company’s U.S. cash tax liability and income tax provision primarily reflected as an increase in the Company’s interest expense limitation offset by a decrease in the Company’s foreign income inclusions.

The nature and terms of Organon’s long-term debt are described in detail in Note 12. “Long-Term Debt and Leases” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

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.

For the three months ended March 31, 2026 the Company had no borrowings or repayments on the Company’s Revolving Credit Facility (the “Revolving Credit Facility”). There were no outstanding balances under the Revolving Credit Facility as of March 31, 2026 or 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:

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 March 31, 2026, the Company is in compliance with all financial covenants, and no default or event of default has occurred.

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:

(a) As part of the divestiture of the Jada System in January 2026, the Company is eligible to receive potential contingent consideration based on the achievement of certain net sales targets for the Jada System during 2026. See Note 3. “Acquisitions and Licensing Arrangements” for further information.

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 (gains) in the Condensed Consolidated Statements of Income. The forward contracts are not designated as hedges and are marked to market through Exchange losses (gains) in the Condensed 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 $1.9 billion and $1.7 billion as of March 31, 2026 and December 31, 2025, respectively. The cash flows and the related gains and losses from these contracts are reported as Operating activities in the Condensed 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. €707 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 10 “Long-Term Debt and Short-Term Borrowings” 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 Condensed 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 Condensed 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 March 31, 2026, 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):

($ in millions)March 31, 2026

In the first quarter of 2026, the Company identified an approximate $12 million error related to the fair value remeasurement of tax‑related contingent consideration, including expected net operating loss utilization. An adjustment was recorded to increase Other (income) expense, net during the first quarter of 2026 and relates to amounts that should have been reflected in the fourth quarter of 2025. The contingent consideration liability is appropriately stated as of March 31, 2026. The error was determined to not be material to the current or previously issued financial statements. 

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 $216 million and $217 million of accounts receivable as of March 31, 2026 and December 31, 2025, respectively, which reduced outstanding accounts receivable. The cash received from the financial institutions is reported within Operating Activities in the Condensed Consolidated Statements of Cash Flows. The cost of factoring such accounts receivable were not material for the three months ended March 31, 2026 and 2025.

Samsung Collaboration Samsung Collaboration
The Company has an agreement with Samsung Bioepis Co., Ltd. (“Samsung Bioepis”) to develop and commercialize multiple pre-specified biosimilar candidates, which have since launched and are part of the Company's product portfolio. 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 March 31, 2026, there was one remaining potential future regulatory milestone payment of $25 million that remained unpaid under the 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 was completed pursuant to the Separation and Distribution Agreement and other agreements with Merck related to the Separation. As of March 31, 2026, only one jurisdiction remains under an Interim Operating Model Agreement.

Under the manufacturing and supply agreements, the Company manufactures certain products for Merck, or its applicable affiliate, and Merck manufactures certain products for the Company, or its applicable affiliate.

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 March 31, 2026, the Fosamax Litigation comprises approximately 508 cases in Federal court, approximately 1,482 cases in New Jersey state court, one case in Pennsylvania state court and approximately 219 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”) associated with the use of Fosamax.

All federal cases alleging femur fractures have been transferred to a multidistrict litigation in the U.S. District Court for the District of New Jersey (the “Femur Fracture MDL”) where the only bellwether case tried to date, Glynn v. Merck, resulted in a verdict in Merck’s favor. Although many cases were previously dismissed on federal preemption grounds, subsequent appellate rulings — including a September 2024 Third Circuit decision and the U.S. Supreme Court’s June 2025 denial of certiorari — resulted in those cases being reinstated and proceeding before the court.

In New Jersey state court, the cases have been consolidated before a single judge in Middlesex County. On July 28, 2025, the Company entered into a Master Settlement Agreement with the New Jersey state and federal plaintiffs’ lawyers who represent eligible clients (“NJ MSA Attorneys”), pursuant to which, in exchange for a confidential, but non-material settlement payment, 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. On February 18, 2026, the Company entered into a Master Settlement Agreement with the California plaintiffs’ lawyers and claimants pursuant to which, in exchange for a confidential, non-material settlement payment, at least 95% of the claimants will release the Company and Merck from any liability related to their claims.

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 California state court. On March 12, 2026, the Company signed a Master Settlement Agreement with the attorneys representing plaintiffs and all but two of the claimants with unfiled cases, pursuant to which, in exchange for a confidential, but non-material settlement payment, all 56 plaintiffs and claimants will release the defendant parties from any liability for their filed and unfiled claims. As of March 31, 2026, Merck had 19 of such cases pending outside the United States, of which seven relate to Implanon and twelve 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 acquired Company 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 acquired Company shares between November 3, 2022 and April 30, 2025. Both actions allege that the 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.

The court consolidated the securities class actions on March 6, 2026, appointed a lead plaintiff and, directed the lead plaintiff to file an amended complaint by May 8, 2026.

The same alleged misconduct also forms the basis of two stockholder derivative lawsuits filed against the Company, and certain of its officers and directors asserting breach of fiduciary duties arising from purportedly materially false and misleading statements. On July 7, 2025, the court consolidated each of the stockholder derivative lawsuits. Subsequently, on September 8, 2025, the court stayed the proceedings pending the final resolution of all motions to dismiss filed in the securities lawsuits.

All of the foregoing actions were filed in the U.S. District Court for the District of New Jersey and 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 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 “Nexplanon matter”). The SEC subsequently opened an investigation into the Nexplanon matter, 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 relating to the Nexplanon matter, 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 Nexplanon matter would likely consume a significant amount of Company resources and result in considerable legal and other 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 March 31, 2026, 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 March 31, 2026 and December 31, 2025 was $9 million and $10 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, other events that could arise in the course of pending litigation, or the filing of new matters, 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.

Basis of Accounting
The accompanying unaudited financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and disclosures required by GAAP for complete consolidated financial statements are not included herein. The results of operations for any interim period are not necessarily indicative of the results of operations for the full year. In the Company’s opinion, all adjustments necessary for a fair statement of these interim statements have been included and are of a normal and recurring nature. All intercompany transactions and accounts within Organon have been eliminated. These interim statements should be read in conjunction with the audited financial statements and notes thereto included in Organon’s Annual Report on Form 10-K for the year ended December 31, 2025.
Use of Estimates
Use of Estimates

The presentation of these Condensed Consolidated Financial Statements and accompanying notes in conformity with GAAP require management to make estimates and assumptions that affect the amounts reported, as further described in the Annual Report on Form 10-K for the year ended December 31, 2025. Accordingly, actual results could differ materially from management’s estimates and assumptions.

Among other things, the ASU adds the scope exception from derivative accounting for contracts that are not exchange-traded and having features based on operations or activities specific to one of the parties involved, reducing complexity and diversity in practice. The amendments in this ASU are effective for annual periods beginning on January 1, 2027, and should be applied on a prospective basis, with the option to apply the amendments on a modified retrospective basis; early adoption is permitted. The Company is currently assessing the impact of this ASU on its consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The amendments modernize the accounting for internal-use software to better reflect contemporary development practices, such as agile and iterative methodologies. Key changes include revised cost capitalization thresholds, enhanced guidance for assessing development uncertainty, and new disclosure requirements intended to improve transparency and consistency across entities. The amendments in this ASU are effective for annual periods beginning on January 1, 2028 and interim reporting periods within those periods, and may be applied either prospectively, retrospectively or on a modified retrospective basis; early adoption is permitted. The Company is currently assessing the impact of this ASU on its consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures, Additionally, in January 2025, the FASB issued ASU 2025-01 to clarify the effective date of ASU 2024-03. The standard requires entities to disaggregate operating expenses into specific categories to provide enhanced transparency into the nature and function of expenses. This guidance is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. This guidance should be applied either prospectively to financial statements issued for reporting periods after the effective date or retrospectively to any or all prior periods presented in the consolidated financial statements. This ASU will have no impact on the Company’s consolidated financial condition or results of operations. The Company is currently evaluating the effects of this guidance on its related disclosures.
