First quarter 2026 revenue of $1.460 billion, down 4% as-reported and down 9% excluding the impact of foreign currency. First quarter 2026 diluted earnings per share of $0.55 and non-GAAP Adjusted diluted earnings per share of $0.71. First quarter 2026 net income of $146 million and Adjusted EBITDA (non-GAAP) of $415 million, representing an Adjusted EBITDA margin of 28.4%. On April 26, 2026, the company announced its pending merger into Sun Pharmaceutical Industries Limited (together with its subsidiaries and/or associated companies, “Sun Pharma”) in an all-cash transaction (the “merger”). The merger is expected to close in early 2027, subject to customary closing conditions, including receipt of required regulatory approvals and approval by Organon stockholders. In light of the pending merger, Organon will not be providing financial guidance or hosting quarterly earnings calls. JERSEY CITY, N.J.--(BUSINESS WIRE)--Organon (NYSE: OGN) today announced its results for the first quarter ended March 31, 2026. First Quarter 2026 Revenue in $ millions Q1 2026 Q1 2025 VPY VPY ex-FX Women’s Health $ 389 $ 463 (16)% (19)% General Medicines Biosimilars 173 141 23% 21% Established Brands 880 887 (1)% (7)% Other (1) 18 22 (15)% (21)% Revenue $ 1,460 $ 1,513 (4)% (9)% Totals may not foot due to rounding and percentages are computed using unrounded amounts. (1) Other includes manufacturing sales to third parties. For the first quarter of 2026, total revenue was $1.460 billion, down 4% on an as-reported basis and down 9% excluding the impact of foreign currency (ex-FX), compared with the first quarter of 2025. Women’s Health revenue declined 16% as-reported and declined 19% ex-FX in the first quarter of 2026, compared with the first quarter of 2025. Sales of Nexplanon® (etonogestrel implant) decreased 21% ex-FX in the first quarter compared with the first quarter of 2025. In the U.S., sales of Nexplanon declined 28% primarily due to both decreased physician demand following the five-year label approval which as expected, has delayed reinsertions; and continued uncertainty around federal funding. Outside of the U.S., Nexplanon sales declined 4% ex-FX, due to the timing of shipments in selective emerging markets, partially offset by increased demand and access in Brazil. Sales of oral contraceptives Marvelon TM (desogestrel and ethinyl estradiol pill) and Mercilon TM (desogestrel and ethinyl estradiol pill) declined 36% ex-FX in the first quarter of 2026 primarily due to decreased demand and market contraction in China and the timing of shipments in Asia Pacific. Global Fertility revenue was down 9% ex-FX as a result of competition-driven price reductions in the U.S. partially offset by modest market growth in China. In January of 2026 the company completed the sale of the Jada® system to Laborie. Biosimilars revenue increased 23% as-reported and 21% ex-FX in the first quarter of 2026, compared with the first quarter of 2025, primarily due to the strong performance of Hadlima® (adalimumab-bwwd) associated with stronger demand in the U.S., and increased demand in Puerto Rico. Biosimilars also benefitted from contribution from new assets, Bildyos® (denosumab-nxxp) and Bilprevda® (denosumab-nxxp) which were approved by the U.S. Food and Drug Administration (“FDA”) in the third quarter of 2025, and Tofidence® (tocilizumab-bavi), which the company acquired in the second quarter of 2025. Established Brands revenue declined 1% as-reported and declined 7% ex-FX in the first quarter of 2026. Revenue contribution from Emgality® (1) (galcanezumab-gnlm) partially offset a decline in the respiratory portfolio, which was driven by pricing pressure, as well as volume declines related to the adoption of revised medical guidelines that deprioritize the use of montelukast, including Singulair® (montelukast sodium) , in various international markets, most recently, in China. Global sales of Dulera® (mometasone furoate and formoterol fumarate dihydrate) also declined in the first quarter of 2026 primarily due to pricing pressure and decreased demand in the U.S. VTAMA ® (tapinarof) grew modestly in the first quarter of 2026 compared with the first quarter of 2025.

Reported gross margin in the first quarter of 2026 was 53.6% compared with 55.6% in the prior year period. Non-GAAP Adjusted gross margin was 59.0% in the first quarter of 2026, compared to 61.7% in the first quarter of 2025. Unfavorable pricing and product mix as well as foreign exchange rates were notable drivers in the decline of both reported gross margin and non-GAAP Adjusted gross margin. Net income for the first quarter of 2026 was $146 million, or $0.55 per diluted share, compared with net income of $87 million, or $0.33 per diluted share, in the first quarter of 2025. For the first quarter of 2026, non-GAAP Adjusted net income was $188 million, or $0.71 per diluted share, compared with $265 million, or $1.02 per diluted share, for the first quarter of 2025. Non-GAAP Adjusted EBITDA margin was 28.4% in the first quarter of 2026 compared with 32.0% in the first quarter of 2025. The year-over-year decline was primarily driven by a decrease in Adjusted Gross Margin. Capital Allocation Today, Organon’s Board of Directors declared a quarterly dividend of $0.02 for each issued and outstanding share of the company's common stock. The dividend is payable on June 11, 2026, to stockholders of record at the close of business on May 11, 2026.

Cautionary Note Regarding Non-GAAP Financial Measures This press release contains “non-GAAP financial measures,” which are financial measures that either exclude or include amounts that are correspondingly not excluded or included in the most directly comparable measures calculated and presented in accordance with U.S. generally accepted accounting principles (“GAAP”). Specifically, the company makes use of the non-GAAP financial measures Adjusted EBITDA, Adjusted EBITDA margin, Adjusted gross margin, Adjusted gross profit, Adjusted net income, Adjusted EPS, and Adjusted diluted EPS, which are not recognized terms under GAAP and are presented only as a supplement to the company’s GAAP financial statements. This press release also provides certain measures that exclude the impact of foreign exchange. We calculate foreign exchange by converting our current-period local currency financial results using the prior period average currency rates and comparing these adjusted amounts to our current-period results. The company believes that these non-GAAP financial measures help to enhance an understanding of the company’s financial performance. However, the presentation of these measures has limitations as an analytical tool and should not be considered in isolation, or as a substitute for the company’s results as reported under GAAP. Because not all companies use identical calculations, the presentations of these non-GAAP measures may not be comparable to other similarly titled measures of other companies. Please refer to Table 4 and Table 5 of this press release for additional information, including relevant definitions and reconciliations of non-GAAP financial measures contained herein to the most directly comparable GAAP measures. The company’s management uses the non-GAAP financial measures described above to evaluate the company’s performance and to guide operational and financial decision making. Further, the company’s management believes that these non-GAAP financial measures, which exclude certain items, help to enhance its ability to meaningfully communicate its underlying business performance, financial condition and results of operations.

Third quarter 2025 revenue of $1.602 billion, up 1% as-reported and down 1% excluding the impact of foreign currency Third quarter 2025 diluted earnings per share of $0.61 and non-GAAP Adjusted diluted earnings per share of $1.01 Third quarter 2025 net income of $160 million and Adjusted EBITDA (non-GAAP) of $518 million, representing an Adjusted EBITDA margin of 32.3% Revenue guidance range for full year 2025 lowered to $6.200 billion to $6.250 billion; Adjusted EBITDA margin guidance lowered to ~31.0% JERSEY CITY, N.J.--(BUSINESS WIRE)--Organon (NYSE: OGN) today announced its results for the third quarter ended September 30, 2025. “I am humbled to be working alongside our talented team during this pivotal time for Organon,” said Joe Morrissey, Organon’s Interim Chief Executive Officer. “We are harnessing the company's many strengths, including a diverse portfolio that we expect will generate more than $900 million in free cash flow before one-time costs this year. We also remain committed to exercising cost discipline and reducing our debt burden proactively, where possible. These actions will create additional balance sheet capacity, positioning us to pursue future growth opportunities in women’s health and further our mission to deliver impactful medicines and solutions for a healthier every day.” Third Quarter 2025 Revenue in $ millions Q3 2025 Q3 2024 VPY VPY ex-FX Women’s Health $ 429 $ 440 (3)% (4)% General Medicines Biosimilars 196 165 19% 19% Established Brands 956 951 1% (3)% Other (1) 21 26 (15)% (18)% Revenue $ 1,602 $ 1,582 1% (1)% Totals may not foot due to rounding and percentages are computed using unrounded amounts.

For the third quarter of 2025, total revenue was $1.602 billion, up 1% on an as-reported basis and down 1% excluding the impact of foreign currency (ex-FX), compared with the third quarter of 2024. Women’s Health revenue declined 3% as-reported and declined 4% ex-FX in the third quarter of 2025, compared with the third quarter of 2024. Sales of Nexplanon® (etonogestrel implant) decreased 9% ex-FX in the quarter compared with the prior year period primarily due to lower demand in the United States primarily driven by decreased funding of government programs, partially offset by increased demand in Brazil and the timing of tenders, primarily in Mexico. Third quarter Nexplanon performance was partially offset with 5% ex-FX growth in NuvaRing® (etonogestrel / ethinyl estradiol vaginal ring), 4% ex-FX growth in MarvelonTM (desogestrel and ethinyl estradiol pill) and MercilonTM (desogestrel and ethinyl estradiol pill), as well as a 29% ex-FX increase in Jada® system. *Estimated net impact from pull-forward Nexplanon revenue associated with the company's sales practices for wholesalers in the U.S. as referenced in the company’s Current Report on Form 8-K, filed with the SEC on October 27, 2025, was approximately $2 million during the third quarter ended September 30, 2025. The company has ceased these sales practices for wholesalers. Biosimilars revenue increased 19% on both an as-reported basis and ex-FX in the third quarter of 2025, compared with the third quarter of 2024, primarily due to strong performance of Hadlima® (adalimumab-bwwd) and the favorable timing of an international tender for Ontruzant® (trastuzumab-dttb). To a lesser extent, during the third quarter the Biosimilars portfolio also benefitted from contribution from new assets; Bildyos® (denosumab-nxxp) and Bilprevda® (denosumab-nxxp), which was approved by the FDA in September 2025, and Tofidence® (tocilizumab-bavi), which the company acquired in the second quarter of 2025. Established Brands revenue increased 1% as-reported and declined 3% ex-FX in the third quarter of 2025. Revenue contribution of Emgality®(1) (galcanezumab-gnlm) and Vtama®(2) (tapinarof) partially offset the impact of the loss of exclusivity (“LOE”) of Atozet™ (ezetimibe and atorvastatin) in key markets in Europe as well as declines in the respiratory portfolio. Performance in the respiratory portfolio was primarily driven by an approximate 40% ex-FX decline in Singulair® (montelukast sodium), due to lower demand outside of the United States and the negative impact from price reductions in Japan and China as well as performance of Dulera® (formoterol and fumarate dihydrate), which declined 30% ex-FX primarily due to the loss of a customer contract in the first part of the year, combined with increased discount rate pressure in the United States, as well as supply constraints.

Reported gross margin in the third quarter of 2025 was 53.5% compared with 58.3% in the prior year period. One-time costs associated with optimizing the company’s manufacturing and supply network was the most significant driver in the year-over-year decline in reported gross margin. Non-GAAP Adjusted gross margin was 60.3% in the third quarter of 2025, compared to 61.7% in the third quarter of 2024. Unfavorable foreign exchange in inventory turns, pricing pressure and product mix were drivers in the decline of both reported gross margin and non-GAAP Adjusted gross margin. Net income for the third quarter of 2025 was $160 million, or $0.61 per diluted share, compared with $359 million, or $1.38 per diluted share, in the third quarter of 2024. For the third quarter of 2025, non-GAAP Adjusted net income was $263 million, or $1.01 per diluted share, compared with $226 million, or $0.87 per diluted share, in 2024. Non-GAAP Adjusted EBITDA margin was 32.3% in the third quarter of 2025 compared with 29.0% in the third quarter of 2024. The year-over-year improvement in Adjusted EBITDA margin was primarily driven by a 14% reduction in non-GAAP operating expenses. Capital Allocation Today, Organon’s Board of Directors declared a quarterly dividend of $0.02 for each issued and outstanding share of the company's common stock. The dividend is payable on December 11, 2025, to stockholders of record at the close of business on November 20, 2025. As of September 30, 2025, cash and cash equivalents were $672 million, and debt was $8.83 billion. Full Year Guidance Organon does not provide GAAP financial measures on a forward-looking basis because the company cannot predict with reasonable certainty and without unreasonable effort, the ultimate outcome of legal proceedings, unusual gains and losses, the occurrence of matters creating GAAP tax impacts, and acquisition-related expenses. These items are uncertain, depend on various factors, and could be material to Organon’s results computed in accordance with GAAP. Full year 2025 financial guidance is presented below on a non-GAAP basis, except revenue. Previous Guidance as of August 5, 2025 Current Guidance Revenue $6.275B - $6.375B $6.200B - $6.250B Nominal revenue growth (2.0%) - (0.4%) (3.2%) - (2.4%) FX translation impact ~$50M headwind ~ $35M - $45M tailwind Ex-FX revenue growth (1.2%) - 0.3% (3.7%) - (3.1%) Adjusted gross margin 60.0%-61.0% Unchanged SG&A Mid 20% range Unchanged R&D Upper single-digit Unchanged IPR&D* $6 million Unchanged Adjusted EBITDA margin (Non-GAAP) 31.0%-32.0% ~31.0% Interest ~$510M Unchanged Depreciation ~$135M Unchanged Effective non-GAAP tax rate 22.5%-24.5% Unchanged Fully diluted weighted average shares outstanding ~263M Unchanged *The company does not provide guidance for forward-looking IPR&D and milestone expense.

Cautionary Note Regarding Non-GAAP Financial Measures This press release contains “non-GAAP financial measures,” which are financial measures that either exclude or include amounts that are correspondingly not excluded or included in the most directly comparable measures calculated and presented in accordance with U.S. generally accepted accounting principles (“GAAP”). Specifically, the company makes use of the non-GAAP financial measures Adjusted EBITDA, Adjusted EBITDA margin, Adjusted gross margin, Adjusted gross profit, Adjusted net income, and Adjusted diluted EPS, which are not recognized terms under GAAP and are presented only as a supplement to the company’s GAAP financial statements. This press release also provides certain measures that exclude the impact of foreign exchange. We calculate foreign exchange by converting our current-period local currency financial results using the prior period average currency rates and comparing these adjusted amounts to our current-period results. The company believes that these non-GAAP financial measures help to enhance an understanding of the company’s financial performance. However, the presentation of these measures has limitations as an analytical tool and should not be considered in isolation, or as a substitute for the company’s results as reported under GAAP. Because not all companies use identical calculations, the presentations of these non-GAAP measures may not be comparable to other similarly titled measures of other companies. Please refer to Table 4 and Table 5 of this press release for additional information, including relevant definitions and reconciliations of non-GAAP financial measures contained herein to the most directly comparable GAAP measures. In addition, the company’s full-year 2025 guidance measures (other than revenue) are provided on a non-GAAP basis because the company is unable to reasonably predict certain items contained in the GAAP measures. Such items include, but are not limited to, acquisition-related expenses, restructuring and related expenses, stock-based compensation, the ultimate outcome of legal proceedings, unusual gains and losses, the occurrence of matters creating GAAP tax impacts and other items not reflective of the company's ongoing operations. The company’s management uses the non-GAAP financial measures described above to evaluate the company’s performance and to guide operational and financial decision making. Further, the company’s management believes that these non-GAAP financial measures, which exclude certain items, help to enhance its ability to meaningfully communicate its underlying business performance, financial condition and results of operations. Cautionary Note Regarding Forward-Looking Statements Except for historical information, this press release includes “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995, including, but not limited to, statements about management’s expectations about Organon’s full-year 2025 guidance estimates and predictions regarding other financial information and metrics, as well as expectations regarding Organon’s franchise and product performance and strategy expectations for future periods.

Organon’s ability to access the public securities and other capital and credit markets in accordance with its financial plans, the cost of such capital and overall condition of the capital and credit markets; actions that may be taken by credit rating agencies that could negatively affect either Organon’s access to or terms of financing or its financial condition and liquidity; Organon’s ability to meet its revenue and growth expectations and outlook; unfavorable publicity and media reports; the potential impact that actions by activist stockholders could have on the pursuit of our business strategies; the loss of key personnel or highly skilled employees;

difficulties with performance of third parties Organon relies on for its business growth; the failure of any supplier to provide substances, materials, or services as agreed, or otherwise meet their obligations to us; the increased cost of supply, manufacturing, packaging, and operations; difficulties developing and sustaining relationships with commercial counterparties; competition from generic products as Organon’s products lose patent protection; any failure by Organon to retain market exclusivity for Nexplanon® (etonogestrel implant) or to obtain an additional period of exclusivity in the United States for Nexplanon subsequent to the expiration of the rod patents in 2027; the continued impact of the September 2024 LOE for Atozet™ (ezetimibe and atorvastatin); the success of our efforts to adapt our business and sales strategies to address the changing market and regulatory landscape in order to achieve our business objectives and remain “competitive;” restructurings or other disruptions at the U.S. Food and Drug Administration (“FDA”), the SEC and other U.S. and comparable government agencies;

the impact of higher selling and promotional costs; changes in government laws and regulations in the United States and other jurisdictions, including laws and regulations governing the research, development, approval, clearance, manufacturing, supply, distribution, and/or marketing of our products and related intellectual property, environmental regulations, and the enforcement thereof affecting Organon’s business; efficacy, safety or other quality concerns with respect to our marketed products, whether or not scientifically justified, leading to product recalls, withdrawals, labeling changes, or declining sales; delays or failures to demonstrate adequate efficacy and safety of Organon’s product candidates in pre-clinical and clinical trials, which may prevent or delay the development, approval, clearance, or commercialization of Organon’s product candidates; future actions of third parties, including significant changes in customer relationships or changes in the behavior and spending patterns of purchasers of health care products and services, including delaying medical procedures, rationing prescription medications, reducing the frequency of physician visits and forgoing health care insurance coverage; legal factors, including product liability claims, antitrust litigation and governmental investigations, including tax disputes, environmental claims and patent disputes with branded and generic competitors, any of which could preclude commercialization of products or negatively affect the profitability of existing products; lost market opportunity resulting from delays and uncertainties in clinical trials and the approval or clearance process of the FDA and other regulatory authorities; the failure by Organon or its third party collaborators and/or their suppliers to fulfill our or their regulatory or quality obligations, which could lead to a delay in regulatory approval or commercial marketing of Organon’s products; cyberattacks on, or other failures, accidents, or security breaches of, Organon’s or third-party providers’ information technology systems, which could disrupt Organon’s operations and those of third parties upon which it relies; increased focus on privacy issues in countries around the world, including the United States, the European Union, and China, and a more difficult legislative and regulatory landscape for privacy and data protection that continues to evolve with the potential to directly affect Organon’s business, including recently enacted laws in a majority of states in the United States requiring security breach notification; changes in tax laws including changes related to the taxation of foreign earnings; the impact of any future pandemic, epidemic, or similar public health threat on Organon’s business, operations and financial performance; loss of key employees or inability to identify and recruit new employees; changes in accounting pronouncements promulgated by standard-setting or regulatory bodies, including the Financial Accounting Standards Board and the SEC, that are adverse to Organon;

For the nine months ended September 30, 2025 and 2024, the GAAP income tax rates were 31.6% and (11.3)%, respectively, and the non-GAAP income tax rates were 24.0% and 19.3%, respectively. These adjustments represent the estimated tax impacts on the reconciling items by applying the statutory rate and applicable law of the originating territory of the non-GAAP adjustments.

(2) Spin-related costs reflect certain costs incurred in connection with activities taken to separate Organon from Merck & Co., Inc., Rahway, NJ, US. These costs include, but are not limited to, $7 million and $47 million for the three and nine months ended September 30, 2024, respectively, for information technology infrastructure, primarily related to the implementation of a stand-alone enterprise resource planning system and redundant software licensing costs, as well as $20 million for the nine months ended September 30, 2024, associated with temporary transition service agreements with Merck & Co., Inc., Rahway, NJ, US. (3) Manufacturing network related costs, including exiting of temporary manufacturing and supply agreements with Merck & Co., Inc., Rahway, NJ, US, reflect accelerated depreciation, exit premiums, technology transfer costs, stability and qualification batch costs, and third-party contractor costs. (4) Acquisition related costs for the three and nine months ended September 30, 2025, reflect the amortization pertaining to the fair value inventory purchase accounting adjustment for the Dermavant transaction. (5) Other costs for the nine months ended September 30, 2025 include $46 million pre-tax gain related to the repurchase and cancellation of approximately $242 million of the 2031 Notes and the repayment and termination of the funding agreement with NovaQuest Co-Investment Fund VIII, L.P. and legal settlement reserves. As the costs described in (1) through (5) above are directly related to the separation of Organon and acquisition related activities and therefore arise from a one-time event outside of the ordinary course of the company’s operations, the adjustment of these items provides meaningful, supplemental, information that the company believes will enhance an investor's understanding of the company's ongoing operating performance.
