2020 Year in Review

CEO Letter

And events throughout the year intensified the need for action in addressing persistent racial injustice within our communities. The impact of all of these will be with us one way or another for quite a long time.

Our Purpose

Biogen is a purpose-driven company that pioneers science for the benefit of humanity. Our steadfast commitment to caring deeply, working fearlessly and changing lives defines every action we take, and inspires us to go where others won’t.

Pioneering Science

Neurological diseases are the leading cause of disability and the second-leading cause of death worldwide. We believe no other disease area holds as much need or as much promise for medical breakthroughs.

Our People

We attract some of the world’s leading innovative minds. Diversity helps to fuel that innovation while fostering an inclusive workplace where people are empowered to learn, grow and build rewarding careers.


We care deeply about creating a healthier, more equitable world by supporting our neighbors in need and engaging the next generation in science, a commitment that spans the globe.


Passionate about improving lives and advancing health access and equity, we apply our pioneering spirit to find new ways to address patient needs and promote better health outcomes.                                         


In a year when some might have slowed environmental initiatives, we pursued firsts in climate, health and equity, launching our most ambitious environmental commitment to date.                                           


Transparency across environmental, social and governance (ESG) issues is a critical part of our ongoing collaboration with key stakeholders, helping to build a community of trust and respect.
