Chiesi Farmaceutici S.p.A. is an Italian family controlled[1][2] global pharmaceutical company based in Parma, Emilia-Romagna. Chiesi has 30 affiliates[3] in the world, nearly 6,389 total employees[4] and provides medicines to patients in 90 nations. Chiesi currently has revenues of 2.229 billion euros.[4] According to 2020 official data from the European Patent Office (EPO), Chiesi Group, with 38 patents filed, is confirmed the first Italian Pharmaceutical Company and fourth among Italian Companies across all sectors for filing the highest number of patents.[5]

In June 2019, Chiesi became a certified B Corporation, thus choosing to adopt a new legal status under US and Italian law. This ensures Chiesi a legal protection to pursue a business model placing social and environmental values on equal footing with profits.[6]

Following the acquisition, in 1999, of Huddersfield based Trinity Pharmaceuticals, Chiesi has also had a significant presence in Manchester, United Kingdom.
