Amendment to Annual Report (Form 10-K/A)

Table of Contents

Explanatory Note

On October 27, 2025, Organon & Co. ("Organon," the "Company," "we," "our," or "us") announced an internal investigation conducted by the Audit Committee (the "Audit Committee") of the Company's Board of Directors (the "Board") regarding the Company's sales practices for wholesalers as described in the Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (the "SEC") on October 27, 2025 (the "Form 8-K"). Following the Audit Committee investigation findings and as a result of the material weaknesses in our internal control over financial reporting that were identified and are described below, the Company is filing this Amendment No. 1 (this "Amendment") to our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 that was filed with the SEC on February 28, 2025 (the "Original Form 10-K").

This Amendment amends and/or restates:

This Amendment also includes the following exhibits to replace exhibits previously filed:

Except as set forth herein, this Amendment does not modify or update disclosures included in the Original Form 10-K, nor does it reflect events occurring after the filing of the Original Form 10-K. Among other things, risk factors and forward-looking statements made in the Original Form 10-K have not been revised to reflect events that occurred or facts that became known to us after the filing of the Original Form 10-K, and any such forward-looking statements should be read in their historical context. Accordingly, this Amendment should be read in conjunction with the Company's filings with the SEC that were made subsequent to the filing of the Original Form 10-K and this Amendment.

Overview of Audit Committee Investigation and Findings

As disclosed in the Form 8-K, after concerns regarding the Company's sales practices for wholesalers for Nexplanon were brought to the Board's attention, the Audit Committee oversaw an independent, internal investigation into these sales practices. The Audit Committee's investigation focused on the Company's sales of Nexplanon to wholesalers. The investigation found that the Company asked two wholesalers in the United States to purchase greater quantities of Nexplanon at the end of the fourth quarter of 2022, the third and fourth quarters of 2024 and the first, second and third quarters of 2025 (collectively, the "Relevant Periods") than they otherwise would have purchased based on wholesaler demand. In certain instances, the Company waived inventory management fee performance metrics associated with caps on days of inventory to allow wholesalers to be paid the inventory management fees they would have earned but for the Company's ask to purchase additional inventory. As a result of these purchases, the United States wholesalers significantly decreased or even halted their purchases of Nexplanon during the early weeks of the following quarters until their days of inventory on hand were reduced to levels within the contractual range. Although the incremental amount of Nexplanon sales that occurred during the Relevant Periods represented less than 1% of the Company's consolidated revenue for the year ended December 31, 2022 or December 31, 2024 as applicable (and less than 2% of the Company's consolidated revenue for the relevant quarterly periods), based on the results of the investigation, the Company has determined that without these sales practices, the Company's consolidated revenue for the fiscal year ended December 31, 2024 reported in the Original Form 10-K (and certain of the other Relevant Periods) would have fallen short of the Company's guidance range and/or certain external expectations. The Audit Committee investigation did not find that the use of these sales practices for wholesalers extended to sales other than sales of Nexplanon in the United States during the Relevant Periods, or that these sales practices for wholesalers were otherwise used for any other Company products.

Table of Contents

In connection with the investigation, the Audit Committee found that (i) the Company's former Chief Executive Officer and leader of the Company's U.S. commercial organization applied inappropriate pressure to achieve sales targets, which resulted in two United States wholesalers being asked to purchase inventory in excess of current customer demand for Nexplanon, (ii) the Company's processes with respect to reporting and documenting the sales practices for wholesalers during the Relevant Periods, including with respect to inventory management fee performance metric waivers, were not followed, (iii) the former Chief Executive Officer did not reasonably ensure that relevant information was appropriately communicated; rather, relevant information was withheld from the Company's independent directors, the Audit Committee, and the independent registered public accounting firm, and (iv) the former Chief Executive Officer and leader of the Company's U.S. commercial organization engaged in inappropriate business conduct that violated the Company's Code of Conduct. There were no investigative findings that other members of the Company's executive leadership team, including the Company's Chief Financial Officer, or any member of the Company's accounting and financial reporting group involved in the preparation of the Company's financial statements, were aware that these sales practices resulted in the United States wholesalers being asked to purchase inventory that exceeded their demand or contractual limits, or that waivers were given so that the United States wholesalers would continue to receive inventory management fees. The Audit Committee's investigation is complete.

Based on the results of the Audit Committee's investigation, the Company determined that these sales practices for wholesalers involving Nexplanon in the United States during the Relevant Periods were improper, and that certain of the Company's prior disclosures relating to these sales practices for wholesalers and their effect upon revenues and product demand in its periodic filings were inaccurate or incomplete, including certain disclosures, as listed above, that are being amended by this Amendment.

Company Determinations Following the Audit Committee Findings

Additionally, as a result of the investigation and the Audit Committee findings, Company management, in consultation with the Audit Committee, has re-assessed the effectiveness of the Company's disclosure controls and procedures and its internal control over financial reporting as of December 31, 2024, as reported in the Original Form 10-K. As a result, the Company has concluded that there were material weaknesses in the Company's internal control over financial reporting as of December 31, 2024 and that management's assessment of its disclosure controls and procedures and its internal control over financial reporting as of December 31, 2024 that were included in Item 9A of the Original Form 10-K should no longer be relied upon, as a result of the material weaknesses described herein. A "material weakness" is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis.

The Company has determined that there will be no restatement or revision to its previously-issued financial statements, including those filed with the Original Form 10-K.

Change in Management

In connection with the Audit Committee investigation, on October 26, 2025, (i) Kevin Ali resigned as Chief Executive Officer of the Company and as a member of the Company's Board of Directors, (ii) Joseph Morrissey, the then-current Executive Vice President and Head of Manufacturing & Supply of the Company, was appointed Interim Chief Executive Officer (and principal executive officer) of the Company, (iii) Carrie S. Cox, Chair of the Board, was appointed Executive Chair for an interim period, and (iv) Robert Essner, a member of the Board, was appointed to the position of Lead Independent Director. Additionally and in connection with the Audit Committee investigation, on October 26, 2025, the Company terminated the employment of its Head of U.S. Commercial & Government Affairs.

Recent Developments

Business Development

Dermavant Sciences Ltd. ("Dermavant")

On October 28, 2024, we acquired Dermavant, a company dedicated to developing and commercializing innovative therapeutics in immuno-dermatology. Dermavant's novel product, Vtama, for the topical treatment of mild, moderate, and severe plaque psoriasis in adults, was approved by the U.S. Food and Drug Administration (the "FDA") in May 2022. 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 allows us to further expand our existing portfolio of established brands and biosimilar dermatology treatments.

Consideration for Dermavant consists of the upfront payment of $175 million and a $75 million milestone payment upon regulatory approval, 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.

During the fourth quarter of 2024, the regulatory milestone related to Vtama's atopic dermatitis indication, which was recorded as part of contingent consideration at fair value, was achieved and recorded in Accrued and other current liabilities. In January 2025, we paid $75 million related to the milestone.

In the fourth quarter of 2024, we 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.

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. SJ02 is a long-acting recombinant human follicle-stimulating hormone carboxyl-terminal peptide fusion protein (FSH-CTP) designed for controlled ovarian stimulation ("COS") in combination with a GnRH antagonist. It is used to facilitate the development of multiple follicles in women undergoing ART programs. Under the terms of the agreement, we will pay $12 million, of which $6 million was paid in the fourth quarter of 2024. In addition, the remaining $6 million is payable upon obtaining the manufacturing license, which is refundable if thereafter either the regulatory approval is not obtained or marketing authorization cannot be transferred. We may owe additional regulatory and sales-based milestones to Centergene of up to $170 million under the terms of the license and supply agreements. We will recognize regulatory and sales-based milestones when the achievement is probable.

Eli Lilly ("Lilly")

In December 2023, we announced an agreement with Lilly to become the sole distributor and promoter of the migraine medicines Emgality and Rayvow in Europe. Lilly will remain the marketing authorization holder and will manufacture the products for sale. Under the terms of the agreement, we 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, we 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, we expanded our 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. We 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, we 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, 2024, we had accrued $20 million in Accrued and Other current liabilities and $240 million in Other noncurrent liabilities in total related to the probable sales-based milestones. In January 2025, we paid $20 million related to the milestones.

in China had a $13 million negative impact on our sales during the year ended December 31, 2024. We expect VBP to continue to impact our established brands product portfolio for the next several quarters.

Our operations include a portfolio of products. Highlights of the sales of our products for the year ended December 31, 2024 and 2023 are provided below. See Note 5 "Product and Geographic Information" to the Consolidated Financial Statements for further details on sales of our products.

Women's Health

Contraception

Worldwide sales of Nexplanon, a single-rod subdermal contraceptive implant, increased 16% for the year ended December 31, 2024, compared to 2023, primarily due to increased sales, favorable price and discount rates in the United States, increased demand and favorable price in international markets and an increase in demand in our institutional business in Africa. The increased sales for Nexplanon included an estimated $15 million as of December 31, 2024 resulting from the identified sales practices for wholesalers described in the "Explanatory Note" above. The impact was estimated using average daily sales, inventory levels at the wholesaler and days on hand at the wholesaler.

Worldwide sales of NuvaRing, a vaginal contraceptive product, declined 35% for the year ended December 31, 2024, compared to 2023, due to ongoing generic competition and the negative impact of increased government discount rates in the United States. We expect a continued decline in NuvaRing sales as a result of generic competition.

Worldwide sales of Marvelon and Mercilon, combined oral hormonal daily contraceptive pills not approved or marketed in the United States, but available in certain countries outside the United States, remained consistent for the year ended December 31, 2024, compared to 2023, as a result of increased demand in various international markets offset by slight declines in China and Japan.

Fertility

Worldwide sales of Follistim AQ, a fertility treatment, declined 10% for the year ended December 31, 2024, compared to 2023, due to a one-time buy-in as a result of our exit from our interim operating model agreement in the United States with Merck, during the fourth quarter of 2023, and unfavorable discount rates in the United States, partially offset by increased demand in the United States and launches in various international markets.

Worldwide sales of ganirelix acetate injection, a fertility treatment, declined 1% for the year ended December 31, 2024, compared to 2023, primarily due to generic competition, partially offset by increased demand in the United States and various international markets.

Other Women's Health

Worldwide sales of Jada, a device intended to provide control and treatment of abnormal postpartum uterine bleeding or hemorrhage when conservative management is warranted, increased 40% for the year ended December 31, 2024, compared to 2023. The sales increase is due to continued uptake in the United States following the Jada launch in early 2022.

Biosimilars

​

Renflexis is a biosimilar to Remicade² (infliximab) for the treatment of certain autoimmune conditions. Sales declined 1% for the year ended December 31, 2024, compared to 2023, primarily due to unfavorable discount rates in the United States partially offset by demand growth in the United States and Canada. We have commercialization rights to Renflexis in countries outside of Europe, Korea, China, Turkey, and Russia.

Ontruzant is a biosimilar to Herceptin² (trastuzumab) for the treatment of HER2-overexpressing breast cancer and HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma. Sales for the year ended December 31, 2024, compared to 2023, declined 9%, driven by lower demand in the United States and Europe partially offset by increased demand as a result of tenders in Brazil. We have commercialization rights to Ontruzant in all countries except in Korea and China.

Brenzys is a biosimilar to Enbrel² (etanercept) for the treatment of certain inflammatory diseases. Sales for the year ended December 31, 2024, compared to 2023, increased 6%, driven by increased demand in Canada. We have commercialization rights to Brenzys in countries outside of the United States, Europe, Korea, China, and Japan.

Hadlima is a biosimilar to Humira² (adalimumab) for the treatment of certain autoimmune and autoinflammatory conditions. We have commercialization rights to Hadlima in countries outside of the EU, Korea, China, Turkey, and Russia. We recorded sales of $142 million during the year ended December 31, 2024, reflecting an increase due to the launch in the United States in July 2023 and a modest increase in international markets. Hadlima is currently approved in the United States, Australia, Canada, and Israel.

Established Brands

Established brands represents a broad portfolio of well-known brands, which generally are beyond market exclusivity, including leading brands in cardiovascular, respiratory, dermatology and non-opioid pain management, for which generic competition varies by market.

Cardiovascular

Combined global sales of Zetia and Vytorin, medicines for lowering LDL cholesterol, declined 6% for the year ended December 31, 2024, compared to 2023, primarily driven by the decrease in demand and mandatory annual price reductions in Japan, partially offset by increased demand in China.

Sales of Atozet, a medicine for lowering LDL cholesterol, declined 9% for the year ended December 31, 2024, compared to 2023, primarily due to LOE in France, Spain, and Japan and the timing of tenders in the Latin America region partially offset by increased demand in certain markets in Europe. We anticipate a continued significant decline in sales of Atozet in 2025 due to LOE, which occurred late in the third quarter of 2024, in certain markets in Europe.

Table of Contents

Combined global sales of Cozaar and Hyzaar, medicines for the treatment of hypertension, declined 14% for the year ended December 31, 2024, compared to 2023, driven by the negative impact of VBP in China and mandatory annual price reductions in Japan.

Respiratory

Worldwide sales of Singulair, a once-a-day oral medicine for the chronic treatment of asthma and for the relief of symptoms of allergic rhinitis, decreased 11% for the year ended December 31, 2024, compared to 2023, due to decreased demand in China and Japan and mandatory annual price reductions in Japan.

Global sales of Nasonex, an inhaled nasal corticosteroid for the treatment of nasal allergy symptoms, increased 4% for the year ended December 31, 2024, compared to 2023, respectively, due to increased demand across international markets.

Global sales of Dulera, which is also marketed as Zenhale in certain markets outside of the United States, a combination medicine for the treatment of asthma, increased 5% for the year ended December 31, 2024, compared to 2023, primarily due to the favorable impact of increased demand in the United States and Canada.

Non-Opioid Pain, Bone and Dermatology

* Calculation not meaningful.

Sales of Arcoxia, a medicine for the treatment of arthritis and pain, increased 5% for the year ended December 31, 2024, compared to 2023, primarily due to increased demand in China and favorable pricing in the Asia Pacific region partially offset by a decrease in demand in various international markets.

Sales of Diprospan, a corticosteroid approved for treatment of a wide range of inflammatory conditions, increased 52% for the year ended December 31, 2024, compared to 2023, due to recovery from the manufacturing issues resulting from the Market Action. In the first quarter of 2023, we resolved the regulatory inspection findings.

Sales of Vtama a cream for the topical treatment of mild, moderate, and severe plaque psoriasis in adults were $12 million for the year ended December 31, 2024, reflecting the acquisition of Dermavant in the fourth quarter of 2024.

Table of Contents

Other

* Calculation not meaningful.

Sales of Emgality and Rayvow were $107 million for the year ended December 31, 2024, reflecting the acquisition of the distribution and promotion rights from Lilly in 2024, in certain markets outside of the United States.

Worldwide sales of Proscar, a medicine for the treatment of symptomatic benign prostate enlargement, declined 2% for the year ended December 31, 2024, compared to 2023, due to decreased demand in China.

Gross Profit, Expenses and Other For the Year Ended December 31, 2024 Compared to 2023

* Calculation not meaningful.

Cost of Sales

Cost of sales increased 7% for the year ended December 31, 2024, compared to 2023, primarily due to higher sales volume, higher inflation impacts to material and distribution costs and amortization of $7 million associated with the inventory fair value adjustment related to the Dermavant acquisition purchase accounting, partially offset by foreign exchange translation. Cost of sales includes amortization of intangible assets which totaled $145 million in 2024, $116 million in 2023 and $116 million in 2022. Amortization for 2024, includes $6 million related to the Dermavant acquired intangibles.

Gross Profit

Gross profit decreased 1% for the year ended December 31, 2024, compared to 2023, due to the impact of unfavorable price, foreign exchange translation and higher inflation impacts to material and distribution costs partially offset by increased sales due to volume.

Selling, General and Administrative

Selling, general and administrative expenses decreased 7% for the year ended December 31, 2024, compared to 2023, due to the $80 million charge in 2023 related to the Microspherix legal matter (as discussed in Note 18 "Contingencies" to the Consolidated Financial Statements in this report) and lower costs associated with the implementation of our Enterprise Resource Planning ("ERP") system, partially offset by increased expenses related to the Dermavant acquisition, including transaction costs of $12 million.

Research and Development

Research and development expenses decreased 11% for the year ended December 31, 2024, compared to 2023, primarily due to a decrease in clinical study activity and lower personnel costs due to a reduction in headcount related to our restructuring initiatives.

Table of Contents

Acquired In-Process Research and Development and Milestones

For the year ended December 31, 2024, acquired in-process research and development and milestones of $81 million primarily represent the research and development milestones of $70 million for our agreement with Henlius and $10 million for our agreement with Cirqle, which were determined to be probable of being achieved. For the year ended December 31, 2023 acquired in-process research and development and milestones of $8 million represent the upfront and development milestones related to the Claria transaction. See Note 3 "Acquisitions and Licensing Arrangements" to the Consolidated Financial Statements included elsewhere in this report for further information regarding our agreements with Henlius and Cirqle.

Restructuring Costs

For the year ended December 31, 2024, we incurred $31 million of headcount-related restructuring expense related to the ongoing optimization of our internal operations, primarily the research and development function. During the first quarter of 2025, we implemented additional restructuring initiatives that will drive operational efficiencies in 2025, and will result in an approximate 5% headcount reduction.

Interest Expense

Interest expense decreased 1% for the year ended December 31, 2024, compared to 2023, reflecting lower interest rates as a result of refinancing a portion of our long-term debt and the impact of our cross-currency swaps, partially offset by interest related to the debt acquired as part of the Dermavant acquisition and approximately $6 million in debt issuance costs related to the refinancing of our long-term debt. Beginning in May 2024, the difference between the interest rate received of 7.3125% and paid of 5.8330% under the cross-currency swap agreements is recorded in Interest expense.

Exchange Losses

Exchange losses decreased 38% for the year ended December 31, 2024, compared to 2023, driven by less volatility in foreign exchange compared to the prior year and the favorable changes in spot rates of our forward contracts.

Other Expense, net

Other expense increased 40% for the year ended December 31, 2024, compared to 2023, due to the fair value adjustment of contingent consideration related to the Dermavant acquisition.

Taxes on Income

The effective income tax rate was (7.1)% and (52.2)% for the year ended December 31, 2024 and 2023, respectively. The effective income tax rate reflects 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 effective tax rate, which was driven by the favorable closure of two non-U.S. tax audits and a return to provision adjustment for the Switzerland entity.

In the third quarter of 2024, the Swiss tax authority confirmed to us the applicable useful life of an existing tax asset. As a result, we have now concluded it is more likely than not we will utilize the entirety of the tax asset. As such, we released a $210 million related valuation allowance.

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 Pillar 2 global corporate minimum tax rate of 15% on companies with revenues of at least €750 million. We have evaluated the impact of this for 2024 and it does not have a material effect on a full year basis.

Sales Overview For the Year Ended December 31, 2023 Compared to 2022

​

Worldwide sales were $6.3 billion for the year ended December 31, 2023, an increase of 1% compared with 2022. Worldwide sales were negatively impacted by approximately 2%, or $117 million, due to unfavorable foreign exchange.

Excluding foreign exchange, sales increases primarily reflect the performance of:

This performance was offset by decreased sales of:

The loss of exclusivity negatively impacted sales of certain of our products by approximately $18 million during the year ended December 31, 2023, compared to the year ended December 31, 2022, due to the decrease in volume period over period, which mainly impacted NuvaRing in the United States. VBP in China had a $95 million negative impact on our sales during the year ended December 31, 2023, compared to the year ended December 31, 2022. We expect VBP to impact our established brands product portfolio for the next several quarters.

Our operations include a portfolio of products. Highlights of the sales of our products for the year ended December 31, 2023 and 2022 are provided below. See Note 6 "Product and Geographic Information" to the Consolidated Financial Statements for further details on sales of our products.

Contraception

Worldwide sales of Nexplanon, a single-rod subdermal contraceptive implant, declined 1% for the year ended December 31, 2023, compared to 2022, primarily due to the impact of foreign exchange, unfavorable discount rates, the result of distributor purchasing patterns associated with the timing of the increase in Nexplanon list price in the United States and the impact of the limited participation of a tender in Mexico. This was partially offset by price increases. Nexplanon sales as of December 31, 2022 included an estimated $23 million from the identified sales practices for wholesalers described in the "Explanatory Note" above, and a wholesaler buy-in prior to a Nexplanon price increase. The impact was estimated using average daily sales, inventory levels at the wholesaler and days on hand at the wholesaler.

Worldwide sales of NuvaRing, a vaginal contraceptive product, declined 19% for the year ended December 31, 2023, compared to 2022, due to ongoing generic competition in the United States. We expect a continued decline in NuvaRing sales as a result of generic competition.

Worldwide sales of Marvelon and Mercilon, combined oral hormonal daily contraceptive pills not approved or marketed in the United States but available in certain countries outside the United States, increased 22% for the year ended December 31, 2023, compared to 2022, as a result of the transaction with Bayer Healthcare where we gained rights in China during the second quarter of 2022 and in Vietnam during the third quarter of 2022.

Fertility

Worldwide sales of Follistim AQ, a fertility treatment, increased 14% for the year ended December 31, 2023, compared to 2022, due to a one-time buy-in as a result of the exit of the IOM in the United States, increased patient demand in the United States and volume recovery in China related to the COVID-19 negative impact during the first half of the year. This was partially offset by the negative impact of unfavorable discount rates in the United States.

Worldwide sales of ganirelix acetate injection, a fertility treatment, declined 10% for the year ended December 31, 2023, compared to 2022, primarily due to unfavorable discount rates in the United States and increased generic competition in Europe.

Other Women's Health

Worldwide sales of Jada, a device intended to provide control and treatment of abnormal postpartum uterine bleeding or hemorrhage when conservative management is warranted, increased 113% for the year ended December 31, 2023, compared to 2022. The sales increase is due to continued uptake in the United States following the Jada launch in early 2022.

Biosimilars

​

Renflexis is a biosimilar to Remicade (infliximab) for the treatment of certain inflammatory diseases. Sales increased 23% for the year ended December 31, 2023, compared to 2022, driven primarily by continued demand growth in the United States and Canada. We have commercialization rights to Renflexis in countries outside Europe, Korea, China, Turkey, and Russia.

Ontruzant is a biosimilar to Herceptin (trastuzumab) for the treatment of HER2-overexpressing breast cancer and HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma. Sales for the year ended December 31, 2023, compared to 2022, increased 28% driven by the timing of tenders in Brazil and increased demand partially offset by the competitive pressures in Europe. We have commercialization rights to Ontruzant in countries outside of Korea and China.

Table of Contents

Brenzys is a biosimilar to Enbrel (etanercept) for the treatment of certain inflammatory diseases. Sales in the year ended December 31, 2023, compared to 2022, remained substantially consistent. We have commercialization rights to Brenzys in countries outside of the United States, Europe, Korea, China, and Japan.

Hadlima is a biosimilar to Humira (adalimumab) for the treatment of certain inflammatory diseases. We have commercialization rights to Hadlima in countries outside of the EU, Korea, China, Turkey, and Russia. We recorded sales of $44 million during the year ended December 31, 2023, reflecting an increase from modest sales during 2022 in markets outside of the United States and the launch in the United States in July 2023. Hadlima is currently approved in the United States, Australia, Canada, and Israel.

Established Brands

Established brands represents a broad portfolio of well-known brands, which generally are beyond market exclusivity, including leading brands in cardiovascular, respiratory, dermatology and non-opioid pain management, for which generic competition varies by market.

Cardiovascular

Combined global sales of Zetia and Vytorin, medicines for lowering LDL cholesterol, declined 10% for the year ended December 31, 2023, compared to 2022, primarily driven by the negative impact of VBP in China.

Sales of Atozet, a medicine for lowering LDL cholesterol, increased 14% for the year ended December 31, 2023, compared to 2022, primarily due to increased demand in various international markets.

Combined global sales of Cozaar and Hyzaar, medicines for the treatment of hypertension, declined 13% for the year ended December 31, 2023, compared to 2022, primarily due to ongoing generic competition.

​

Worldwide sales of Singulair, a once-a-day oral medicine for the chronic treatment of asthma and for the relief of symptoms of allergic rhinitis, declined 2% for the year ended December 31, 2023, compared to 2022, due to the impact of foreign exchange partially offset by increased demand due to higher incidences of respiratory conditions across many international markets during the fourth quarter of 2023 compared to 2022.

Global sales of Nasonex, an inhaled nasal corticosteroid for the treatment of nasal allergy symptoms, increased 2% for the year ended December 31, 2023, compared to 2022, due to increased demand across several markets partially offset by a $10 million milestone related to a regulatory approval received during the first quarter of 2022.

Table of Contents

Global sales of Dulera, a combination medicine for the treatment of asthma, increased 8% for the year ended December 31, 2023, compared to 2022, primarily due to the favorable impact from price and increased demand in the United States.

Non-Opioid Pain, Bone and Dermatology

Gross Profit, Expenses and Other For the Year Ended December 31, 2023 Compared to 2022

​

* Calculation not meaningful.

Cost of Sales

Cost of sales increased 10% for the year ended December 31, 2023, compared to 2022, primarily due to foreign exchange translation, higher employee-related and material and distribution related costs, which increased as a result of inflationary pressures, and product mix. During the year ended December 31, 2022, we recorded a $36 million inventory charge relating to the Market Action and an impairment charge of $9 million related to a product right for a biosimilar product. Cost of sales includes amortization of intangible assets which totaled $116 million in 2023, $116 million in 2022 and $103 million in 2021.

Table of Contents

Selling, General and Administrative

Selling, general and administrative expenses increased 11% for the year ended December 31, 2023, compared to 2022, due to higher employee-related costs, costs incurred in connection with the separation from Merck, which includes the implementation of the enterprise resource planning system, and the $80 million charge related to the Microspherix legal matter as discussed in Note 20. "Contingencies" to the Consolidated Financial Statements. This was partially offset by lower promotional expenses.

Research and Development

Research and development expenses increased 12% for the year ended December 31, 2023, compared to 2022, primarily due to higher costs associated with our acquisitions of clinical stage assets, increased clinical study activity and higher employee-related costs.

Acquired In-Process Research and Development and Milestones

For the year ended December 31, 2023, acquired in-process research and development and milestones of $8 million related to the Claria transaction. For the year ended December 31, 2022 acquired in-process research and development and milestones represents the upfront and development milestones related to our research collaboration and license agreement with Cirqle and our agreement with Henlius for the license of certain biosimilar candidates.

Restructuring Costs

For the year ended December 31, 2023, we incurred $62 million of headcount-related restructuring expense, of which $58 million is due to activities initiated in the fourth quarter related to the ongoing optimization of our internal operations.

Interest Expense

Interest expense increased 25% for the year ended December 31, 2023, compared to 2022, due to increased interest rates, and debt fees and discounts expensed as part of the prepayment on the U.S. Dollar-denominated term loan and the impact of exchange rates.

Exchange Losses

For the year ended December 31, 2023, the change in exchange losses was driven by foreign currency exchange translation losses and the impact of the portion of Euro-denominated debt not designated as a net investment hedge in the prior year period.

Other Expense, net

For the year ended December 31, 2023, other expense, net, remained relatively consistent with the prior year.

Taxes on Income

The effective income tax rates were (52.2)% and 18.3% for the year ended December 31, 2023 and 2022, 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. In the fourth quarter of 2023, we recorded a $476 million tax benefit comprised of a gross benefit of $686 million, net of a $210 million valuation allowance, resulting from the termination of a Swiss tax arrangement. Our valuation allowance was determined based on expected future income and the terms of the remaining tax arrangement.

On August 16, 2022, the United States enacted the Inflation Reduction Act of 2022. Provisions of the bill that relate to tax include the minimum tax on book income, a 1% excise tax on stock buybacks and certain tax incentives to promote clean energy. There are no impacts of the legislation to the 2023 results. We will continue to assess future impacts of this legislation.

Liquidity and Capital Resources

As of December 31, 2024, we had cash and cash equivalents of $675 million. We have historically generated and expect to continue to generate positive cash flow from operations. Our ability to fund our operations and anticipated capital needs is reliant upon the generation of cash from operations, supplemented as necessary by periodic utilization of our revolving credit facility. Our principal uses of cash in

Table of Contents

the future will be primarily to fund our operations, working capital needs, capital expenditures, repayment of borrowings, payment of dividends and strategic business development transactions. We believe that our financing arrangements, future cash from operations, and access to capital markets will provide adequate resources to fund our future cash flow needs.

During the second and fourth quarters of 2024, we refinanced a portion of our long-term debt. These transactions extended certain maturity dates, resulted in lower interest rates for certain of our long-term debt and increased the capacity of our revolving credit facility. See Note 12 "Long-Term Debt and Leases" to the Consolidated Financial Statements included elsewhere in this report for further information on our long-term debt transactions.

Working capital is defined as current assets less current liabilities and was $1.6 billion as of December 31, 2024 and December 31, 2023, respectively. Working capital was impacted by our active cash cycle management, including the factoring of receivables and timing of vendor payments.

We have accounts receivable factoring agreements with financial institutions in certain countries. Under these agreements, we have factored $186 million of our accounts receivable as of December 31, 2024.

Net cash provided by operating activities was $939 million for the year ended December 31, 2024, compared to $799 million for the same period in the prior year. The increase in cash provided by operating activities was primarily attributable to our favorable operating performance and cash cycle working capital, partially offset by higher cash taxes paid and higher severance-related payments.

Net cash used in investing activities was $513 million for the year ended December 31, 2024, compared to $260 million for the same period in the prior year, primarily due to the Dermavant acquisition, the $73 million upfront payments related to the agreement with Lilly and the additional $71 million payments related to milestones, partially offset by lower capital spending as a result of the completion of the implementation of our ERP system.

Net cash used in financing activities was $368 million for the year ended December 31, 2024, compared to $569 million for the same period in the prior year. The decrease in cash used in financing activities was driven by the $250 million voluntary prepayment on the U.S. dollar-denominated term loan in the year ended December 31, 2023, compared to a $7.5 million discretionary prepayment on the U.S. dollar-denominated term loan and $38 million of debt issuance costs related to the long-term debt refinancing in the year ended December 31, 2024.

As part of our post-spinoff plan, we have approved an initiative to further optimize our manufacturing and supply network. As part of this initiative, we will continue to separate our supply chain through planned exits from supply agreements from Merck through 2031. This will enable us to redefine our appropriate sourcing strategy, and move to fit-for-purpose supply chains, while focusing on delivering efficiencies. We anticipate we will incur costs associated with this separation, including but not limited to accelerated depreciation, exit premiums and fees, technology transfer costs, stability and qualification batch costs, one-time resourcing costs, regulatory and filing costs, capital investment, and inventory stock bridges.

For the year ended December 31, 2024 and 2023, our combined revenues from Ukraine, Russia and Israel were approximately 2% of total revenues. While we will continue to monitor the impacts of the Ukraine-Russia war and the Hamas-Israel conflict, as of December 31, 2024, our assets in Ukraine, Russia and Israel are not material.

Contractual Obligations

Our contractual obligations as of December 31, 2024, which require material cash requirements in the future, consist of contractual milestones, purchase obligations and lease obligations.

Contractual milestones are potential payments based upon the achievement of specified milestones associated with business development transactions. Such milestone payments will only be payable in the event that our collaborative partners achieve contractually defined success-based milestones such as the advancement of the specified research and development programs or the receipt of regulatory approval for the specified compounds or products and/or we reach a sales threshold of the specified compounds or products. The timing of the payments of the contractual milestones are uncertain and the likelihood of achieving the milestones cannot be determined. As of December 31, 2024, total potential payments for contractual milestones are $3.4 billion. Potential amounts to be paid within the next twelve months are $218 million.

Table of Contents

Purchase obligations are enforceable and legally binding obligations for purchases of goods and services which include inventory purchase commitments. As of December 31, 2024, total payments due for purchase obligations are $850 million and extend through 2032. Amounts due within the next twelve months are $356 million.

Long-term debt consists of both fixed and variable-rate instruments. As of December 31, 2024, total payments due for debt obligations are $9.0 billion and extend through 2034. Amounts due within the next twelve months are $8 million.

Lease obligations exclude reasonably certain lease renewals that have not yet been executed. As of December 31, 2024, total payments due for lease obligations are $177 million and extend through 2041. Amounts due within the next twelve months are $49 million.

During 2024, we paid cash dividends of $1.12 per share. On February 13, 2025, our Board of Directors declared a quarterly dividend of $0.28 for each issued and outstanding share of our common stock. The dividend is payable on March 13, 2025, to stockholders of record at the close of business on February 24, 2025.

Critical Accounting Estimates

The audited annual consolidated financial statements are prepared in conformity with U.S. GAAP and, accordingly, include certain amounts that are based on management's best estimates and judgments. A discussion of accounting estimates considered critical because of the potential for a significant impact on the financial statements due to the inherent uncertainty in such estimates are disclosed below. Because of the uncertainty inherent in such estimates, actual results may differ from these estimates.

Revenue Recognition

Our accounting policy for revenue recognition has a substantial impact on reported results and relies on certain estimates. Revenue is recognized following a five-step model: (i) identify the customer contract; (ii) identify the contract's performance obligation; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligation; and (v) recognize revenue when or as a performance obligation is satisfied. Revenue is reduced for gross-to-net sales adjustments discussed below, all of which involve significant estimates and judgment after considering applicable laws and regulations and definitive contractual agreements with private sector and public sector benefit providers. These types of variable consideration 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 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. Estimates are assessed each period and adjusted as required to revise information or actual experience.

In the United States, revenue is reduced by sales discounts issued to customers at the point-of-sale, through an intermediary wholesaler (known as chargebacks), or in the form of rebate amounts owed based upon definitive contractual agreements or legal requirements with private sector (Managed Care) and public sector (Medicaid and Medicare Part D) customers. Additionally, sales are generally made with a limited right of return under certain conditions.

The provision for aggregate customer discounts in the United States covers chargebacks and rebates. We determine the provision for chargebacks based on expected sell-through levels by our wholesale customers to contracted customers, as well as estimated wholesaler inventory levels. 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. We use 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 in order to estimate the expected provision. 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.

We continually monitor our provision for aggregate customer discounts. There were no material adjustments to estimates associated with the aggregate customer discount provision in 2024, 2023, or 2022.

Table of Contents

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

Accruals for chargebacks are reflected as a direct reduction to accounts receivable and accruals for rebates as current liabilities. The accrued balances relative to these provisions included in accounts receivable and accrued and other current liabilities were $100 million and $380 million, respectively, at December 31, 2024, $87 million and $417 million, respectively, at December 31, 2023 and $78 million and $307 million, respectively, at December 31, 2022. The increase in accrued rebates in 2023 is attributable to a wholesaler buy-in in conjunction with the exit of the interim operating model with Merck for the Follistim product.

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. In certain European countries, legislatively mandated rebates are calculated based on an estimate of the government's total unbudgeted spending and our specific payback obligation. Rebates may also be required based on specific product sales thresholds. We apply an estimated factor against our actual invoiced sales to represent the expected level of future discount or rebate obligations associated with the sale.

We maintain a returns policy that allows our 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. Additionally, we consider factors such as levels of inventory in the distribution channel, product dating and expiration period, whether products have been discontinued, entrance in the market of generic competition, changes in formularies or launch of over-the-counter products, among others.

See Note 2 "Summary of Accounting Policies" to the Consolidated Financial Statements included in this report for additional details on our revenue recognition policy.

Contingencies and Environmental Liabilities

We are involved in various claims and legal proceedings of a nature considered normal to our business, including product liability, intellectual property, and commercial litigation, as well as certain additional matters including governmental and environmental matters. See Note 18 "Contingencies" to the Consolidated Financial Statements included in this report. We record accruals for contingencies when it is probable that a liability has been incurred and the amount can be reasonably estimated.

Legal defense costs expected to be incurred in connection with a loss contingency are accrued when probable and reasonably estimable.

We believe that there are no compliance issues associated with applicable environmental laws and regulations that would have a material adverse effect on us. Expenditures for remediation and environmental liabilities were $3 million in 2024, and are estimated at $14 million in the aggregate for the years 2025 through 2029. Liabilities for all environmental matters that are probable and reasonably estimable have been accrued and totaled $16 million and $19 million at December 31, 2024 and 2023, respectively. 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 13 years. Although it is not possible to predict with certainty the outcome of these matters, or the ultimate costs of remediation, we do not believe that any reasonably possible expenditures that may be incurred in excess of the liabilities accrued should exceed $23 million in the aggregate. We also do not believe that these expenditures should result in a material adverse effect on our financial condition, results of operations or liquidity for any year.

Impairments of Long-Lived Assets

We assess changes in economic, regulatory and legal conditions and make assumptions regarding estimated future cash flows in evaluating the value of our property, plant and equipment, goodwill and intangible assets. The judgments made in evaluating impairment of long-lived intangibles can materially affect our results of operations.

Table of Contents

We periodically evaluate whether current facts or circumstances indicate that the carrying values of our long-lived assets to be held and used 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 asset's fair value and its carrying value. If quoted market prices are not available, we estimate fair value using a discounted value of estimated future cash flows approach.

Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses acquired. Goodwill is evaluated for impairment as of October 1 each year, 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. Some of the factors considered in the assessment include general macroeconomic conditions, conditions specific to the industry and market, cost factors which could have a significant effect on earnings or cash flows, and overall financial performance. If we conclude 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). We completed the annual qualitative goodwill impairment test as of October 1, 2024 and concluded that there was no impairment to goodwill as the fair value of the reporting unit was significantly in excess of the carrying value.

Intangible assets are initially recorded at fair value, assigned an estimated useful life, and amortized primarily on a straight-line basis over their estimated useful lives. When events or circumstances warrant a review, we will assess recoverability from future operations using pretax undiscounted cash flows derived from the lowest appropriate asset groupings. Potential risks leading to impairment could include LOE occurring earlier than expected, competition, pricing reductions, and other macroeconomic changes. Impairments are recognized in operating results to the extent that the carrying value of the intangible asset exceeds its fair value, which is determined based on the net present value of estimated future cash flows. We did not have impairment charges as of December 31, 2024 and 2023. We recorded impairment charges of $9 million as of December 31, 2022. See Note 11 "Intangibles" to the Consolidated Financial Statements included in this report for additional details on Intangibles.

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. We establish valuation allowances for our deferred tax assets when the amount of expected future income is not likely to support the use of the deduction or credit. We evaluate 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, we recognize the largest amount of the benefit that is greater than 50% likely of being realized upon ultimate settlement in the financial statements. For tax positions that are not more likely than not of being sustained upon audit, we do not recognize any portion of the benefit in the financial statements. We recognize interest and penalties associated with uncertain tax positions as a component of Taxes on Income in the consolidated statement of income.

Inventory Valuation

Inventories consist of currently marketed products and are valued at the lower of cost or net realizable value. Inventories are assessed regularly for impairment and valuation reserves are established when necessary based on a number of factors including, but not limited to, product obsolescence and changes in estimates of future product demand and expiry. The determination of events and the assumptions utilized in our quantification of valuation reserves may require judgment. No material adjustments have been required to our inventory reserve estimates for the periods presented. Adverse changes in assumptions utilized in our inventory reserve calculations could result in an increase to our inventory valuation reserves and higher cost of sales.

Acquisitions

Business combinations are evaluated in order to determine whether transactions should be accounted for as acquisitions of assets or businesses. We make certain judgments, which include assessment of the inputs, processes, and outputs associated with the acquired set of activities. If we determine that substantially all of the fair value of gross assets included in a transaction is concentrated in a single asset (or a group of similar assets), we account for the transaction as an asset acquisition. In an asset acquisition, acquired in-process research and development ("IPR&D") with no alternative future use is charged to expense and contingent consideration is not recognized at the acquisition date. Product development milestones are recognized upon achievement and sales-based milestones are recognized when the milestone is deemed probable of being achieved. No goodwill is recorded in an asset acquisition.

To be considered a business, the assets in a transaction need to include an input and a substantive process that together significantly contribute to the ability to create outputs. Businesses acquired are consolidated upon obtaining control. The fair value of assets acquired

Table of Contents

and liabilities assumed are recognized at the date of acquisition. Assets acquired and liabilities assumed in a business combination that arise from contingencies are generally recognized at fair value. If fair value cannot be determined, the asset or liability is recognized if probable and reasonably estimable; if these criteria are not met, no asset or liability is recognized. Any excess of the purchase price over the estimated fair values of the net assets acquired is recognized as goodwill. Business acquisition costs are expensed when incurred.

The fair values of identifiable intangible assets related to currently marketed products are primarily determined by using an income approach through which fair value is estimated based on each asset's discounted projected net cash flows. Our estimates of market participant net cash flows consider historical and projected pricing, margins and expense levels; the performance of competing products and the current and expected competition environment where applicable; relevant industry and product growth drivers and factors; product life cycles; the ability to obtain additional marketing and regulatory approvals; the ability to manufacture and commercialize the products; and the life of each asset's underlying patent and related patent term extension, if any. The net cash flows are then discounted to present value utilizing an appropriate discount rate.

The fair values of identifiable intangible assets related to IPR&D are also determined using an income approach, through which fair value is estimated based on each asset's probability-adjusted future net cash flows, which reflect the different stages of development of each product and the associated probability of successful completion. The net cash flows are then discounted to present value using an appropriate discount rate. Amounts allocated to acquired IPR&D are capitalized and accounted for as indefinite-lived intangible assets, subject to impairment testing until completion or abandonment of the projects. Upon successful completion of each IPR&D project, we 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.

Certain of our business combinations involve the potential for future payment of consideration that is contingent upon the achievement of performance milestones, including product development milestones and royalty payments on future product sales. The fair value of contingent consideration liabilities is determined at the acquisition date using unobservable inputs. These inputs include the estimated amount and timing of projected cash flows, the probability of success (achievement of the contingent event) and the risk-adjusted discount rate used to present value the probability-weighted cash flows. Subsequent to the acquisition date, at each reporting period until the contingency is resolved, the contingent consideration liability is remeasured at current fair value with changes (either expense or income) recorded in earnings in Other expense, net. Changes in any of the inputs may result in a significantly different fair value adjustment.

Pension

Our pension plans are calculated using actuarial assumptions including a discount rate for plan benefit obligations and an expected rate of return on plan assets. These significant assumptions are reviewed annually and are disclosed in Note 14 "Pension and Other Postretirement Benefit Plans" to the Consolidated Financial Statements included in this report.

For our pension plans, the discount rate is evaluated on measurement dates 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 for the pension plans 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. In developing the expected rate of return, we consider long-term compound annualized returns of historical market data, current market conditions and actual returns on our plan assets. Using this reference information, we develop forward-looking return expectations for each asset category and a weighted-average expected long-term rate of return for a target portfolio allocated across these investment categories. The expected portfolio performance reflects the contribution of active management as appropriate.

Stock-Based Compensation

We expense all stock-based payment awards to employees, including grants of stock options, over the requisite service period based on the grant date fair value of the awards. The fair value of certain stock-based awards is determined using the Black-Scholes option-pricing model which uses both historical and current market data to estimate the fair value. This method incorporates various assumptions such as the risk-free interest rate, expected volatility, expected dividend yield and expected life of the options.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Organon & Co.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Organon & Co. and its subsidiaries (the "Company") as of December 31, 2024 and 2023, and the related consolidated statements of income, of comprehensive income, of stockholders' equity (deficit) and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company did not maintain, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO because material weaknesses in internal control over financial reporting existed as of that date related to the Company (i) failing to set an appropriate tone at the top which resulted in violations of the Company's code of conduct, and (ii) not designing or maintaining effective controls related to providing complete information and appropriate communication between the former CEO and certain senior members of the Company's U.S. commercial organization and the Company's disclosure committee and financial reporting group to evaluate disclosures and financial reporting conclusions related to sales practices for wholesalers.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses referred to above are described in Management's Report on Internal Control Over Financial Reporting appearing under Item 9A. We considered these material weaknesses in determining the nature, timing, and extent of audit tests applied in our audit of the 2024 consolidated financial statements, and our opinion regarding the effectiveness of the Company's internal control over financial reporting does not affect our opinion on those consolidated financial statements.

Restatement of Management's Conclusion Regarding Internal Control over Financial Reporting

Management and we previously concluded that the Company maintained effective internal control over financial reporting as of December 31, 2024. However, management has subsequently determined that material weaknesses in internal control over financial reporting existed as of that date related to the Company (i) failing to set an appropriate tone at the top which resulted in violations of the Company's code of conduct and (ii) not designing or maintaining effective controls related to providing complete information and appropriate communication between the former CEO and certain senior members of the Company's U.S. commercial organization and the Company's disclosure committee and financial reporting group to evaluate disclosures and financial reporting conclusions related to sales practices for wholesalers. Accordingly, management's report has been restated and our present opinion on internal control over financial reporting, as presented herein, is different from that expressed in our previous report.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in management's report referred to above. Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Table of Contents

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

U.S. Rebate Accruals - Medicaid and Managed Care Rebates

As described in Note 2 to the consolidated financial statements, the Company records certain variable consideration including discounts, which are estimated at the time of sale generally using the expected value method. Amounts accrued, included in accrued and other current liabilities, for aggregate customer discounts as of December 31, 2024 in the United States was $380 million, of which the majority related to U.S. rebate accruals for Medicaid and Managed Care. These rebate accruals 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. Certain of these discounts are in the form of rebates, which 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. Management 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 in order to estimate the expected provision.

The principal considerations for our determination that performing procedures relating to U.S. rebate accruals for Medicaid and Managed Care is a critical audit matter are (i) the significant judgment by management when developing these rebate accruals; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management's significant assumptions related to pricing information and historical customer segment utilization mix; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Table of Contents

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to provisions for U.S. Medicaid and Managed Care rebates. These procedures also included, among others (i) developing an independent estimate of the U.S. rebate accruals for Medicaid and Managed Care by utilizing third-party data on historical customer segment utilization mix in the U.S., pricing information, the terms of the specific rebate programs, and the historical trends of actual rebate claims paid; (ii) comparing the independent estimate to the U.S. rebate accruals for Medicaid and Managed Care recorded by management; and (iii) testing, on a sample basis, actual rebate claims paid for U.S. Medicaid and Managed Care, including evaluating those claims for consistency with the contractual terms of the Company's rebate agreements. Professionals with specialized skill and knowledge were used to assist in evaluating the reasonableness of the pricing information used in the Medicaid portion of the accrual.
