AmeriSource Health Corporation and Bergen Brunswig Corporation announced a merger agreement in March 2000. The deal closed on August 29, 2001, creating AmerisourceBergen Corporation. At the time of the merger, AmeriSource traced its origins to 1977 and Bergen Brunswig dated to 1907 as a pharmaceutical wholesaler.
The combined company became one of the three dominant US pharmaceutical distributors alongside McKesson Corporation and Cardinal Health. This three-company structure for US wholesale drug distribution has remained stable for two decades.
In 2012, Walgreens Company (now Walgreens Boots Alliance) entered a strategic partnership with AmerisourceBergen that gave Walgreens the right to purchase up to 19.5% of AmerisourceBergen shares over time in exchange for long-term distribution contracts. Walgreens ultimately accumulated approximately 28% of the company's shares, making it the largest single shareholder.
In 2014, AmerisourceBergen acquired PharMEDium Services, a specialty compounding and sterile drug preparation company, for approximately $2.58 billion. In 2017, it acquired MWI Veterinary Supply and H.D. Smith, expanding into veterinary supply and community pharmacy distribution.
In 2021, AmerisourceBergen acquired Alliance Healthcare, a European pharmaceutical distribution company, from Walgreens Boots Alliance for approximately $6.5 billion. This acquisition marked a significant expansion into international markets.
On August 21, 2023, the company officially changed its name from AmerisourceBergen Corporation to Cencora Inc. The company stated the new name was intended to reflect its broader international scope and its identity beyond the original pharmaceutical distribution brands. The NYSE ticker changed from ABC to COR.

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.

Opioid Distribution Lawsuits and Settlement (2021-2022): AmerisourceBergen was a defendant in litigation filed by thousands of state and local governments alleging that the three major drug distributors (McKesson, AmerisourceBergen, and Cardinal Health) contributed to the opioid epidemic by distributing excessive quantities of opioid painkillers without adequate suspicious order monitoring. In July 2021, the three distributors announced a settlement framework of approximately $21 billion to be paid over 18 years to states, counties, and municipalities. AmerisourceBergen's portion was approximately $6.1 billion. The companies did not admit liability in the settlement.
DEA Suspicious Order Monitoring Settlement (2020): In September 2020, AmerisourceBergen agreed to pay $25.6 million to settle DEA-related allegations concerning suspicious order reporting requirements for Schedule II controlled substances. The settlement related to a subsidiary, Rochester Drug Co-operative, which AmerisourceBergen had acquired. This was separate from the broader state opioid litigation.
Cencora Cybersecurity Incident (2024): In February 2024, Cencora's internal IT systems were breached. The company disclosed the incident in May 2024, reporting that patient data from pharmaceutical manufacturer patient support programs, which Cencora administers, was exfiltrated. The breach affected approximately 30 pharmaceutical companies' patient support program data. Cencora notified affected individuals and regulators and paid remediation costs. Multiple pharmaceutical manufacturers disclosed the incident in their own filings. The total costs of the breach, including litigation, were not fully resolved as of June 2026.
Market Concentration Scrutiny: Federal and state regulators have periodically raised concerns about the concentration of US pharmaceutical distribution among three companies. As of June 2026, no antitrust enforcement action has been taken directly against Cencora.
