Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background and Nature of Operations	Background and Nature of Operations Organon & Co. (“Organon” or the “Company”) is an independent global healthcare company with a focus on improving the health of women throughout their lives. Organon develops and delivers innovative health solutions through a portfolio of prescription therapies and medical devices within women’s health, biosimilars and established brands (the “Organon Products”). Organon has a portfolio of more than 60 medicines and products across a range of therapeutic areas. The Company sells these products through various channels including drug wholesalers and retailers, hospitals, government agencies and managed health care 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. Unless otherwise indicated, trademarks appearing in italics throughout this document are trademarks of, or are used under license by, the Organon group of companies. The Company’s operations include the following product portfolios: • Women’s Health : Organon’s women’s health products are 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, which is a class of contraceptives that is recognized as one of the most effective types of hormonal contraception available to patients with a low long-term average cost. 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, and a license from Daré Biosciences for the global commercial rights to Xaciato ® (clindamycin phosphate vaginal gel, 2%), an FDA-approved medication for the treatment of bacterial vaginosis (“BV”) in females 12 years of age and older. In October 2023, Xaciato was launched in the United States. • Biosimilars : Organon’s current portfolio spans across immunology and oncology treatments. Organon’s oncology biosimilars, Ontruzant® (trastuzumab-dttb) and Aybintio TM 1 (bevacizumab), have been launched in more than 20 countries, Organon’s immunology biosimilars, Brenzys TM 1 (etanercept), Renflexi s ® (infliximab-abda) and Hadlima® (adalimumab-bwwd), have been launched in five countries. All five biosimilars in Organon’s portfolio have launched in Canada, and three biosimilars, Ontruzant , Renflexis and Hadlima have launched in the United States. • Established Brands : Organon has a portfolio of established brands, which generally are beyond market exclusivity, including leading brands in cardiovascular, respiratory, dermatology and non-opioid pain management. A number of Organon’s established brands lost exclusivity years ago and have faced generic competition for some time.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 of 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, 2023. 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, 2023. Accordingly, actual results could differ materially from management’s estimates and assumptions. Recently Issued Accounting Standards Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Improvements to Income Tax Disclosures , which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. The amendments in this ASU are effective for annual periods beginning on January 1, 2025, and should be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. This ASU will have no impact on the Company’s consolidated financial condition or results of operations. The Company is currently evaluating the impact to its income tax disclosures. In November 2023, the FASB issued ASU No. 2023-07, Improvements to Reportable Segment Disclosure s, which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. The amendments in this ASU are effective for annual periods beginning on January 1, 2024 and interim periods beginning on January 1, 2025, and should be applied on a retrospective basis for all periods presented. This ASU will have no impact on the Company’s consolidated financial condition or results of operations. The Company is currently evaluating the impact to its segment disclosures. Recent Securities and Exchange Commission (“SEC”) Final Rules Not Yet Adopted In March 2024, the SEC adopted final rules under SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors , which requires registrants to provide certain climate-related information in their registration statements and annual reports. The rules require information about a registrant's climate-related risks that are reasonably likely to have a material impact on its business, results of operations, or financial condition. The required information about climate-related risks will also include disclosure of a registrant's greenhouse gas emissions. In addition, the rules will require registrants to present certain climate-related financial metrics in their audited financial statements. These requirements are effective for the Company in various fiscal years, starting with its fiscal year beginning January 1, 2025. However, the climate rule is currently stayed which could potentially impact the effective date. Disclosures will be required prospectively, with information for prior periods required only to the extent it was previously disclosed in an SEC filing. The Company is currently evaluating the impact of these final rules on its consolidated financial statements and disclosures.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation Plans	Stock-Based Compensation Plans The Company grants stock option awards, performance share units (“PSUs”) and restricted share units (“RSUs”) pursuant to its 2021 Incentive Stock Plan. The PSU awards are based on the following performance factors: • total stockholder return of the Company relative to an index of peer companies specified in the awards; and • the results of cumulative free cash flow 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 PSUs will be based on the fair value of the underlying common stock once the grant date is determined. Stock-based compensation expenses incurred by the Company were as follows: Three Months Ended Six Months Ended ($ in millions) 2024 2023 2024 2023 Stock-based compensation expense recognized in: Cost of sales $ 5 $ 4 $ 9 $ 8 Selling, general and administrative 18 17 36 32 Research and development 5 4 9 7 Total $ 28 $ 25 $ 54 $ 47 Income tax benefits $ 6 $ 5 $ 11 $ 10 The fair value of options granted was determined using the following assumptions: Six Months Ended June 30, 2024 2023 Expected dividend yield 6.00 % 4.82 % Risk-free interest rate 4.12 3.56 Expected volatility 41.02 42.30 Expected life (years) 5.89 5.89 A summary of the equity award transactions for the six months ended June 30, 2024 is as follows: Stock Options RSUs PSUs (shares in thousands) Shares Weighted average exercise price Weighted average grant date fair value Shares Weighted average grant date fair value Shares Weighted average grant date fair value Outstanding as of January 1, 2024 5,758 $ 32.20 $ 8.51 7,511 $ 25.05 1,122 $ 30.16 Granted/Issued 1,503 18.80 4.59 4,683 18.80 184 31.25 Vested/Exercised — — — (2,898) 29.52 — — Forfeited/Cancelled (301) 28.81 7.57 (648) 22.23 (75) 27.08 Outstanding as of June 30, 2024 6,960 $ 29.45 $ 7.70 8,648 $ 20.38 1,231 $ 30.51 The following table summarizes information about equity awards outstanding that are vested and expected to vest and equity awards outstanding that are exercisable as of June 30, 2024: Equity Awards Vested and Expected to Vest Equity Awards That are Exercisable (awards in thousands; aggregate intrinsic value in millions) Awards Weighted Average Exercise Price Aggregate Intrinsic Value Remaining Term (in years) Awards Weighted Average Exercise Price Aggregate Intrinsic Value Remaining Term (in years) Stock Options 6,734 $ 29.45 $ 3 7.08 4,310 $ 33.40 $ — 5.88 RSUs 7,909 179 2.16 PSUs 912 21 1.66 The amount of unrecognized compensation costs as of June 30, 2024 was $191 million, which will be recognized in operating expense ratably over the weighted average vesting period of 2.14 years.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring In the first quarter of 2024, Organon implemented additional restructuring activities related to the ongoing optimization of its internal operations by reducing headcount, primarily in the Research and Development function. In the fourth quarter of 2023, Organon implemented restructuring activities related to the ongoing optimization of its internal operations by reducing headcount in certain markets and functions. As a result of these combined activities, the Company’s headcount will be reduced by approximately 5% by the end of 2024. Organon expects the remaining severance payments associated with the restructuring activities to be paid 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 : June 30, 2024 December 31, 2023 Beginning balance $ 61 $ 20 Severance & severance related costs 23 62 Cash payments and other (46) (21) Ending Balance $ 38 $ 61

Income Tax Disclosure [Abstract]
Taxes on Income	Taxes on Income The effective income tax rates were 17.3% and 5.0% for the three months ended June 30, 2024 and 2023, respectively, and 16.0% and 14.4% for the six months ended June 30, 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 partial valuation allowance recorded against non-deductible U.S. interest expense. There was a favorable impact to the 2024 year-to-date effective tax rate which was driven by the favorable closure of the two non-US tax audits and a return to provision adjustment for the Switzerland entity. Effective January 1, 2024, multiple jurisdictions, most notably, a majority of the European Union member states, implemented the Organization for Economic Co-operation and Development’s (“OECD”) Pillar 2 global corporate minimum tax rate of 15% on companies with revenues of at least €750 million. The Company has evaluated the effect of this for the first two quarters of 2024 and does not expect that it will have a material effect on a full year basis.

The nature and terms of Organon’s long-term debt are described in detail in Note 16. “Long-Term Debt and Leases” in the 2023 Annual Report on Form 10-K for the year ended December 31, 2023. 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 are 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. On May 17, 2024, Organon entered into Amendment No. 2 to the Senior Secured Credit Agreement (“Amendment No. 2”) which, among other things, (i) extended the maturity of the U.S. Dollar Term Loan B Facility to May 17, 2031, (ii) extended the maturity of the revolving credit loans made under the senior secured credit facility (the “Revolving Facility”) to December 2, 2027, (iii) increased the maximum amount of the Revolving Facility by $300 million and decreased the commitment fee payable in respect of the Revolving 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 B Facility from Term SOFR plus 3.0% to Term SOFR plus 2.50%. During the second quarter of 2024, the Company borrowed $36 million on the Revolving Facility and subsequently repaid the amount on June 17, 2024. As of June 30, 2024 there were no outstanding balances under the Revolving Facility. During the second quarter of 2024, the Company recorded approximately $36 million of deferred debt issuance costs and discounts related to the long-term debt. Debt issuance costs and discounts are presented as a reduction of debt on the Condensed Consolidated Balance Sheets and are amortized as a component of interest expense over the term on the related debt using the effective interest method. Long-term debt was recorded at the carrying amount. The estimated fair value of long-term debt (including current portion) is as follows: ($ in millions) June 30, 2024 December 31, 2023 Long-term debt $ 8,333 $ 8,253 Fair value 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 asset or liability and would be considered Level 2 in the fair value hierarchy. The Company made interest payments related to its debt instruments of $247 million for the six months ended June 30, 2024. The average maturity of the Company’s long-term debt as of June 30, 2024 is approximately 5.7 years and the weighted-average interest rate on total borrowings as of June 30, 2024 is 5.4%. On June 26, 2024, the Company made a discretionary prepayment of $7.5 million on the U.S. Dollar-denominated term loan. The schedule of principal payments required on long-term debt for the next five years and thereafter is as follows: ($ in millions) 2024 $ 5 2025 9 2026 9 2027 9 2028 4,187 Thereafter 4,545 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 June 30, 2024, the Company is in compliance with all financial covenants and no default or event of default has occurred.

Financial Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	Financial Instruments 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 Japanese yen. 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 (gains) losses in the Condensed Consolidated Statements of Income . The forward contracts are not designated as hedges and are marked to market through Exchange (gains) losses 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 $1.5 billion and $1.4 billion as of June 30, 2024 and December 31, 2023, 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. €728 of the euro-denominated term loan and €1,250 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” for additional details. Cross-Currency Swaps In conjunction with the issuance of the 2034 Notes, 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 will be recorded in Other Comprehensive Income. 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 $1 billion. The notional amount based on the Euro leg of the cross-currency swaps has been designated and is effective as a hedge of the net investment in euro-denominated subsidiaries. The difference between the interest rate received and paid under the cross-currency swap agreements is recorded in Interest expense in the Condensed Consolidated Statements of Income. The cash flows and the related gains and losses from the cross-currency swaps are reported as operating activities in the Condensed Consolidated Statements of Cash Flows. The Company measures fair value based on the prices that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based on a three-tier hierarchy that prioritizes the inputs used to measure fair value. These tiers include Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. The following financial instruments were recorded at their estimated fair value. The recurring fair value measurement of the assets and liabilities were as follows: ($ in millions) Fair Value Measurement Level June 30, 2024 December 31, 2023 Forward contracts in Other current assets 2 $ 18 $ 9 Cross-currency swap in Long term assets 2 4 — Forward contracts in Accrued and other current liabilities 2 9 16 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: Three Months Ended Six Months Ended ($ in millions) 2024 2023 2024 2023 Euro-denominated debt instruments $ 26 $ (16) $ 75 $ (58) Cross-currency swaps 4 — 4 — The Condensed Consolidated Statements of Income include the impact of net (gains) losses of Organon’s derivative financial instruments: Three Months Ended Six Months Ended ($ in millions) 2024 2023 2024 2023 Derivative gain in Exchange (gains) losses $ (8) $ (13) $ (9) $ (13) Derivative gain in Interest expense (2) — (2) — Concentrations of Credit Risk Organon has established accounts receivable factoring agreements with financial institutions in certain countries to sell accounts receivable.

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 June 30, 2024, potential future regulatory milestone payments of $25 million remain under the agreement.

Contingencies

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) what 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 the coverage that is available 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 June 30, 2024, approximately 3,115 cases comprising the Fosamax Litigation are pending against Merck in either federal or 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 or will be transferred to a multidistrict litigation in 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. In August 2013, the Femur Fracture MDL court entered an order requiring plaintiffs in the Femur Fracture MDL to show cause why those cases asserting claims for a femur fracture injury that took place prior to September 14, 2010, should not be dismissed based on the court’s preemption decision in the Glynn case. Pursuant to the show cause order, in March 2014, the Femur Fracture MDL court dismissed with prejudice approximately 650 cases on preemption grounds. Plaintiffs in approximately 515 of those cases appealed that decision to the U.S. Court of Appeals for the Third Circuit (“Third Circuit”). In March 2017, the Third Circuit issued a decision reversing the Femur Fracture MDL court’s preemption ruling and remanding the appealed cases back to the Femur Fracture MDL court. In May 2019, the U.S. Supreme Court decided that the Third Circuit had incorrectly concluded that the issue of preemption should be resolved by a jury, and accordingly vacated the judgment of the Third Circuit and remanded the proceedings back to the Third Circuit to address the issue in a manner consistent with the Supreme Court’s opinion. In November 2019, the Third Circuit remanded the cases back to the District Court in order to allow that court to determine in the first instance whether the plaintiffs’ state law claims are preempted by federal law under the standards described by the Supreme Court in its opinion. On March 23, 2022, the District Court granted Merck’s motion and ruled that plaintiffs’ failure to warn claims are preempted as a matter of law to the extent they assert that Merck should have added a Warning or Precaution regarding atypical femur fractures prior to October 2010. On July 11, 2022, the District Court entered an Order to Show Cause as to why the Court should not dismiss either with prejudice or conditionally all of plaintiffs’ claims that are not dependent on the preempted failure to warn claims. On November 18, 2022, as a result of the Order to Show Cause, the District Court entered a Final Judgment resulting in the dismissal with prejudice of all plaintiffs in the MDL. On December 16, 2022, those plaintiffs filed their Notice of Appeal to the Third Circuit challenging the District Court’s preemption ruling. 974 of the 975 cases previously pending in the Femur Fracture MDL have either been dismissed or are on appeal to the Third Circuit. Plaintiff’s motion to remand one case back to its transferor court is pending. The appeal to the Third Circuit has been fully briefed and oral arguments occurred on March 5, 2024. As of June 30, 2024, approximately 1,860 cases alleging Femur Fractures have been filed in New Jersey state court and are pending in Middlesex County. The parties selected an initial group of cases to be reviewed through fact discovery, and Merck continues to select additional cases to be reviewed. As of June 30, 2024, approximately 275 cases alleging Femur Fractures have been filed and are pending in California state court. All of the Femur Fracture cases filed in California state court have been consolidated before a single judge in Orange County, California. Additionally, there are four Femur Fracture cases pending in other state courts. Discovery is presently stayed in the Femur Fracture MDL and in the state court in California. 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. As of June 30, 2024, Merck had 21 cases pending outside the United States, of which 11 relate to Implanon and 10 relate to Nexplanon . Governmental Proceedings From time to time, Organon’s subsidiaries may receive inquiries and may be the subject of preliminary investigation activities from competition 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. 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 In June 2017, Microspherix LLC (“Microspherix”) sued Organon in the U.S. District Court for the District of New Jersey asserting that the manufacturing, use, sale and importation of Nexplanon infringed several of Microspherix’s patents that claim radio-opaque, implantable drug delivery devices. Microspherix claimed damages from September 2014 until the patents expired in May 2021. In December 2023, the parties executed a settlement agreement and the district court dismissed the case. Organon made its first payment of $35 million in December 2023, its second payment of $25 million in August 2024, and has reserved $20 million to cover the remainder of the settlement. Other Litigation 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 June 30, 2024, 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 June 30, 2024 and December 31, 2023 was $18 million and $20 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, it believes it would be appropriate to do so.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 of 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, 2023.
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, 2023. Accordingly, actual results could differ materially from management’s estimates and assumptions.
Recently Issued Accounting Standards Not Yet Adopted	Recently Issued Accounting Standards Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Improvements to Income Tax Disclosures , which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. The amendments in this ASU are effective for annual periods beginning on January 1, 2025, and should be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. This ASU will have no impact on the Company’s consolidated financial condition or results of operations. The Company is currently evaluating the impact to its income tax disclosures. In November 2023, the FASB issued ASU No. 2023-07, Improvements to Reportable Segment Disclosure s, which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. The amendments in this ASU are effective for annual periods beginning on January 1, 2024 and interim periods beginning on January 1, 2025, and should be applied on a retrospective basis for all periods presented. This ASU will have no impact on the Company’s consolidated financial condition or results of operations. The Company is currently evaluating the impact to its segment disclosures. Recent Securities and Exchange Commission (“SEC”) Final Rules Not Yet Adopted In March 2024, the SEC adopted final rules under SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors , which requires registrants to provide certain climate-related information in their registration statements and annual reports. The rules require information about a registrant's climate-related risks that are reasonably likely to have a material impact on its business, results of operations, or financial condition. The required information about climate-related risks will also include disclosure of a registrant's greenhouse gas emissions. In addition, the rules will require registrants to present certain climate-related financial metrics in their audited financial statements. These requirements are effective for the Company in various fiscal years, starting with its fiscal year beginning January 1, 2025. However, the climate rule is currently stayed which could potentially impact the effective date. Disclosures will be required prospectively, with information for prior periods required only to the extent it was previously disclosed in an SEC filing. The Company is currently evaluating the impact of these final rules on its consolidated financial statements and disclosures.
