Exhibit 99.1

Organon reports results for the third quarter ended September 30, 2021

Jersey City, N.J., November 11, 2021 – Organon (NYSE: OGN) (the “company”), today announced its results for the third quarter and year to date ended September 30, 2021.

Organon also announced that its Board of Directors declared a quarterly dividend of $0.28 for each issued and outstanding share of the company's common stock. The dividend is payable on December 16, 2021 to stockholders of record at the close of business on November 22, 2021.

"Just months after becoming a standalone company, we are delivering on what we set out to do. Our year to date results are very much in line with expectations, and with good visibility into the remainder of the year, we are affirming our financial guidance," said Kevin Ali, Organon's CEO. "Importantly, we have also been disciplined in actioning business development opportunities that have been in the works well prior to spin. Including today's announcement regarding the proposed acquisition of Forendo Pharma, we have executed three transactions in the last six months, demonstrating our commitment to advance innovation in large, underserved markets, which women’s health has lacked for decades."

Third quarter 2021 revenue

Total net revenue was $1,600 million for the third quarter of 2021, a decrease of 1% as-reported and 3% excluding the impacts of foreign currency (ex-FX), compared with the third quarter of 2020.

Women’s Health declined 10% as-reported and 11% ex-FX in the third quarter 2021 compared with the third quarter of 2020, driven primarily by a 17% ex-FX decline in NUVARING® (etonogestrel/ethinyl estradiol vaginal ring) which continues to be impacted by generic competition, and also NEXPLANON® (etonogestrel implant), which declined 8% ex-FX in the third quarter 2021. In September 2020, there was short-lived resurgence in patient well visits that positively impacted third quarter 2020 NEXPLANON sales, which is a physician-administered product. Throughout the current year, well visits in the US continue to be suppressed by the COVID-19 pandemic, hampering NEXPLANON sales. The decline in the company's contraception portfolio was partially offset by the fertility franchise, led by FOLLISTIM®, AQ Cartridge (follitropin beta injection) which grew 18% ex-FX, and was positively impacted by a combination of COVID-19 recovery and increased demand.

Biosimilars revenue grew 41% as-reported and 39% ex-FX in the third quarter 2021 compared with third quarter 2020, driven by continued demand growth in the US for RENFLEXIS® (infliximab-abda), since its launch in 2017 as well as growth in Canada. The biosimilars portfolio also benefited from the continued uptake of ONTRUZANT® (trastuzumab-dttb) in the US since the July 2020 launch in the US, as well as strong performance in Brazil, partially offset by a decrease in the EU reflecting increasing competitive pressures and tenders lost.

Established Brands represents a broad portfolio of well-known medicines, which are generally beyond market exclusivity, including leading brands in cardiovascular, respiratory, dermatology and non-opioid pain management, and for which generic competition varies by market. Revenue for Established Brands was down 6% as-reported and down 8% ex-FX in the third quarter of 2021. Excluding the impact of loss of exclusivity (LOE), Established Brands revenue was down 4% ex-FX. During the quarter, retail expansion in China grew 20% and partially offset impacts from decreases in the hospital channel due to Volume Based Procurement (VBP). The portfolio impacts from LOE as well as VBP were partially offset by a 3% ex-FX increase in respiratory medicines. SINGULAIR® (montelukast) was up 20% ex-FX due to higher volume and recovery from the COVID-19 pandemic in China, despite its exposure to VBP, and NASONEX® (mometasone) was up 13% ex-FX due to higher demand in China and favorable performance in Russia, partially offset by generic competition in Japan.

Third quarter 2021 profitability

⁽¹⁾ See Tables 4,5 and 6 for reconciliations of GAAP to non-GAAP measures

Gross margin was 61.9% as-reported and 64.9% on an adjusted basis in the third quarter of 2021 compared with 66.8% as-reported and 68.6% on an adjusted basis in the third quarter of 2020. The year-over-year decrease reflects costs of standing up Organon as an independent company, including certain costs related to manufacturing agreements between the company and its former parent company, which have lower gross margin percentages compared to third party product sales and purchases. Those manufacturing agreements had an approximate 180 basis point negative impact to gross margins.

Adjusted EBITDA margin was 39.8% in the third quarter of 2021 compared with 46.6% in the third quarter of 2020, which reflects costs incurred to establish Organon as a stand alone entity.

Net income from continuing operations for the third quarter of 2021 was $323 million, or $1.27 per diluted share, compared with $560 million, or $2.21 per diluted share, in the third quarter of 2020. Non-GAAP Adjusted net income from continuing operations was $424 million, or $1.67 per diluted share, compared with $604 million, or $2.38 per diluted share, in 2020.

Capital Allocation

Today, Organon’s Board of Directors declared a quarterly dividend of $0.28 for each issued and outstanding share of the company's common stock. The dividend is payable on December 16, 2021 to stockholders of record at the close of business on November 22, 2021.

As of September 30, 2021, cash and cash equivalents were $1,008 million, and debt was $9,298 million, resulting in net debt of $8,290 million.

Full year guidance – all guidance provided on a Non-GAAP basis

Organon does not provide GAAP financial measures on a forward-looking basis because the company is unable to predict with reasonable certainty and without unreasonable effort, the ultimate outcome of legal proceedings, unusual gains and losses, 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.

The company affirmed all financial guidance, and narrowed the ranges for revenue and Adjusted EBITDA margin. The financial guidance is presented on a non-GAAP basis and is proforma as if Organon was a standalone company for the entire year.

Non-GAAP results, such as Adjusted EBITDA, Adjusted Net Income, and Adjusted Diluted EPS, are presented only as a supplement to the company’s financial statements based on GAAP. Non-GAAP financial information is provided to enhance understanding of the company’s financial performance, but none of these non-GAAP financial measures are recognized terms under GAAP, and non-GAAP measures should not be considered in isolation from, or as a substitute analysis for, the company’s results of operations as determined in accordance with GAAP. Definitions and reconciliations of non-GAAP

measures to the most directly comparable GAAP measures are provided within the schedules attached to this release. The company uses non-GAAP measures in its operational and financial decision making, and believes that it is useful to exclude certain items in order to focus on what it regards to be a more meaningful representation of the underlying operating performance of the business. The company also believes that investors may find non-GAAP financial measures useful for the same reasons, although investors are cautioned that non-GAAP financial measures are not a substitute for GAAP disclosures. The non-GAAP financial measures are not presented in accordance with GAAP. Please refer to the appendix of this press release for reconciliations of non-GAAP financial measures contained herein to the most directly comparable GAAP measures. The company’s full-year 2021 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 and other items not reflective of the company's ongoing operations.
