Serono operated in 44 countries, with manufacturing facilities in eight countries and sales in over 90 countries. Main manufacturing sites were in Switzerland, Italy, Spain and France; a fifth facility in Israel was closed in 2004 owing to its obsolescence. Research and development facilities were maintained in Geneva, Switzerland, Boston, USA, and Ivrea, Italy. It employed over 4,750 people with worldwide revenues of USD 2,586.4 million (2005). It had eight biotechnology products on the market, and more than 25 ongoing preclinical and clinical development projects at the end of 2005.
Serono Headquarters and the Geneva research site moved to a brand new campus (Horizon Secheron) in the heart of Geneva in 2006. This facility and the headquarters were closed by Merck KGaA in 2013. The building was sold back to a consortium composed of the Bertarelli family and Hansjörg Wyss, who retained it as a life sciences hub for the Lake Geneva region, now called Campus Biotech.

In 2005, Serono agreed to a $704 million settlement with the Department of Justice to resolve civil and criminal allegations that the company engaged in a fraudulent scheme to promote the drug Serostim for off-label uses and paid out illegal kickbacks for prescribing the drug in violation of the False Claims Act. The settlement is, to date, the ninth largest pharmaceutical settlement in U.S. history.
