The company operates through distinct business segments, each dedicated to advancing patient care through innovative therapies and preventive solutions.
In its pharmaceuticals segment, Sanofi develops and markets biologics and small molecules designed to treat chronic and acute conditions. The company’s specialty care division focuses on treatment for rare diseases, multiple sclerosis and oncology, while its general medicines unit provides treatments for established therapeutic areas such as cardiovascular health and internal medicine.

Sanofi Consumer Healthcare extends the company’s reach into over-the-counter remedies, vitamins and nutritional supplements, enhancing overall wellness and self-care.
Sanofi traces its modern structure to the 2004 merger of Sanofi-Synthélabo and Aventis, which brought together complementary portfolios in pharmaceuticals and vaccines. In 2011, the company simplified its branding to “Sanofi,” uniting its global operations under a single identity. Over the years, Sanofi has expanded through strategic acquisitions and collaborations, strengthening its pipeline in emerging fields such as gene therapy, mRNA vaccines and digital health. The company maintains an active research presence with multiple R&D centers in Europe, North America and Asia, collaborating with academic institutions and industry partners to accelerate innovation.
Today, Sanofi employs more than 100,000 people worldwide and serves patients in over 100 countries. The company has significant commercial operations across Europe, North America, Latin America, Asia and Africa, leveraging local expertise to address regional health challenges. Since September 2019, Sanofi has been led by Chief Executive Officer Paul Hudson, under whose stewardship the company has emphasized agility in research, patient-centricity and sustainable growth. Sanofi continues to pursue a long-term vision of improving global health through scientific excellence, expansive access programs and a commitment to corporate responsibility.
