CORPORATE RESPONSIBILITY REPORT
Building on our legacy of inventing sustainable solutions for a healthier tomorrow.

From discovering breakthrough medicines and vaccines, to engaging in partnerships to expand access to health care, Merck's history is defined not only by the medicines and vaccines we've invented, but by the lives we've impacted around the world. Corporate responsibility is at the core of Merck's mission and drives us to find innovative solutions to the world's most pressing global health needs while building our business in a sustainable way. Our 2015/2016 Corporate Responsibility Report illustrates our ongoing quest to save and improve lives through innovation while also strengthening the health of communities around the world.

READ THE REPORT

Merck's corporate responsibility approach has four focus areas:

188 million people reached through our major programs and partnerships

99% of employees trained on our Code of Conduct

2.5 billion gallons of water saved over the past 6 years

34% of executive roles held by women

Access to Health, Environmental Sustainability, Employees, and Ethics and Transparency. These focus areas lie at the heart of our company's mission to invent, develop, manufacture and deliver the very best products to people around the world.

We're proud of the partnerships that we have forged and all that we have accomplished, as detailed in the 2015/2016 Corporate Responsibility Report. Highlights include:

Protecting the lives of mothers and children through Merck for Mothers

Attaining all three of our environmental goals ahead of schedule

Significantly increasing business with diverse suppliers and small enterprises

Initiating a volunteerism campaign in recognition of the company's 125th anniversary

Advancing our pipeline in areas of significant unmet medical need, including cancer, Alzheimer's disease, the hepatitis C virus and life-threatening infections

Recognizing retired Merck scientist William Campbell for receiving the 2015 Nobel Prize in Medicine or Physiology for his discovery leading to a treatment for river blindness

Expanding the reach of our Animal Health business through new products and educational initiatives

The greatest challenge for science is to think globally, think simply and act accordingly…One part of the world affects another part. We have a moral obligation to look after each other.

- Former Merck employee and 2015 Nobel laureate Dr. William Campbell

It was in this spirit that Dr. Campbell and his team discovered avermectin, which in turn led to a treatment for river blindness. In 1987, his discovery led to an unprecedented act of global health care leadership: the decision to donate the treatment - as much as needed for as long as needed - through the Mectizan Donation Program.

Today, we continue to seek more ways to fight diseases and support patients through our efforts to develop innovative solutions in priority disease areas, coupled with programs such as the Alliance to Advance Patient-Centered Cancer Care, the HIV Care Collaborative, and Merck for Mothers, among many others.

We believe that our scientific and business contributions have helped make the world a healthier, stronger, and more hopeful place...And we believe that our future will be even better as we continue to seek novel and sustainable solutions that improve both health and society.

- Kenneth C. Frazier, chairman and chief executive officer, Merck
