US Bioservices was founded in Texas in the mid-1990s as a specialty pharmaceutical services provider focused on high-cost, complex therapies. By 2002, it had built a national operation managing reimbursement support and clinical services for patients on specialty medications, generating approximately $120 million in annual revenue.
AmerisourceBergen signed a definitive agreement to acquire the company in December 2002 and completed the deal on January 17, 2003. The $160 million base purchase price came with contingent payments of up to $30 million tied to earnings targets through early 2004. At the time, roughly 58 percent of US Bioservices was owned by private equity firm Whitney and Company.
For AmerisourceBergen, the deal added a specialty pharmacy capability to complement its core drug distribution business at a moment when specialty pharmaceuticals were beginning their long climb to more than half of total US drug spending. US Bioservices gave the distributor direct patient contact: dispensing, benefits investigation, clinical support, and adherence programs.
Under the parent's umbrella, US Bioservices expanded its therapeutic coverage across oncology, hepatitis C, multiple sclerosis, immune disorders, and rare diseases, and participated in limited-distribution networks where manufacturers restrict dispensing to select pharmacies. The 2023 corporate rebrand to Cencora left the US Bioservices name unchanged, preserving its independent identity within the larger organization.

Why did AmerisourceBergen change its name to Cencora?
AmerisourceBergen changed its name to Cencora on August 30, 2023, to reflect its evolution from a primarily domestic pharmaceutical distributor into a global healthcare solutions organization. The rebranding followed the 2021 acquisition of Alliance Healthcare from Walgreens Boots Alliance for approximately $6.5 billion, which significantly expanded the company's international operations. The new name was selected from hundreds of possibilities and was inspired by the company's team members and customers around the world. The ticker symbol changed from ABC to COR on the same date.

Cencora (then AmerisourceBergen), along with McKesson and Cardinal Health, reached a $21 billion settlement with U.S. states and local governments in February 2022 to resolve claims that the three distributors failed to adequately monitor suspicious opioid orders. Cencora's share of the settlement is approximately $6.1 billion, representing its 31% portion, to be paid over 18 years. A minimum of 85% of the settlement payments must be used for addiction treatment and prevention services. The distributors did not admit liability or wrongdoing. A separate settlement with Johnson & Johnson brought the total to approximately $26 billion.
What is the RCA acquisition?
In January 2025, Cencora completed the acquisition of Retina Consultants of America (RCA), a leading management services organization of retina specialists, from Webster Equity Partners.

The acquisition added nearly 300 retina specialists to Cencora's portfolio and expanded its physician management services capabilities within the U.S. Healthcare Solutions segment.
