Organon Launches as New Global Women s Health Company

Only company of its size focused on women s health

Launching with a commitment to listen to women to understand her health needs and help identify solutions that are urgently needed

Jersey City, N.J., June 3, 2021 Organon (NYSE: OGN), today celebrates its launch as a global women s health company with employees and women

from around the world, as the Organon executive leadership team rings the opening bell at the New York Stock Exchange (NYSE). Recognizing the need to listen to and act on women s experiences to address the challenges in women s health,

Organon gathered voices from around the world to create the Wall of Voices, a multimedia installation outside of the NYSE.

Organon focuses on women s everyday health needs, with a focus on reproductive health, health issues that are unique to women, as well as

conditions that disproportionately affect women. The Wall of Voices shares powerful perspectives, voices and images of women from around the world highlighting these health issues and serves as a symbol of Organon s commitment.

Women everywhere are invited to take the microphone to add their voice to the digital Wall of Voices at HereForHerHealth.com.

At Organon, we are here for her health. Our vision is to create a better and healthier every day for every woman around the world. There

is no other healthcare company with our global footprint dedicated to putting women at the center that will focus on identifying medicines and solutions that they so urgently need, said Kevin Ali, Chief Executive Officer, Organon. The

time is right for Organon to bring forward more options for women and healthcare providers to help shape the future of women s health.

Diverse Portfolio will Drive Sustainable Growth

At launch, Organon s portfolio will consist of more than 60 medicines and products across an international footprint that serves people in

more than 140 markets, with nearly 80% of its approximately $6.5 billion in annual revenue generated outside the U.S. Organon believes it is well positioned for organic low-to-mid-single digit growth from its 2021 base of business.

Organon has three core

pillars that will benefit from renewed management focus and commercial investment:

Women at the Center: Organon s Approach to Innovation

Organon s R&D philosophy is to build a business around patient needs, with the goal of identifying and advancing healthcare options

for women that enable them to live their best lives every day.

For too long, for too many common conditions, such as heavy,

painful, and irregular menstrual bleeding, incontinence and menopause and many others, women have been told to accept and normalize these conditions as a part of life, said Sandy Milligan, Head of Organon Research & Development.

Organon s mission is to change this. We believe this approach will be very successful we hope to discover the ability to identify diseases earlier, the ability to modify the course of diseases or healthcare conditions and to

ultimately, improve the quality of life for women at all stages.

The company s extensive global capabilities in clinical development and patient safety,

regulatory and medical affairs make it well-positioned to identify promising drugs, diagnostics and devices with the greatest potential to impact women s health.

Majority Female Board of Directors Will Guide Team of Committed Employees

Organon believes the journey to improve women s health is foundational to the gender equity it wants to see in its organization. The

representation of women on the Board comprising 70% of positions is higher than any S&P 500 healthcare company. Together with Organon s employees, a global community of approximately 9,000 strong, they are united in their

drive to better support the health of women around the globe.

A live webcast of the Opening Bell from the exchange will be available on

the NYSE website today from 9:30 a.m. EST.

Organon (NYSE: OGN) is a global healthcare company formed through a spinoff from Merck to focus on improving the health of women throughout their lives. Here

for her health, the company has a portfolio of more than 60 medicines and products across a range of therapeutic areas. Led by the reproductive health portfolio coupled with an expanding biosimilars business and stable franchise of established

medicines, Organon s products produce strong cash flows that will support investments in future growth opportunities in women s health, including business development. In addition, Organon is pursuing opportunities to collaborate with

biopharmaceutical innovators looking to commercialize their products by leveraging its scale and presence in fast growing international markets.

Organon has a global footprint with significant scale and geographic reach, world-class commercial capabilities, and approximately 9,000

employees with headquarters located in Jersey City, New Jersey.
