AmerisourceBergen Receives DEA Order to Temporarily Halt Distribution of Controlled Substances from Its Orlando, Florida Facility

April 24, 2007

The DEA asserts that AmerisourceBergen did not maintain effective controls against diversion of controlled substances, specifically hydrocodone, to four internet pharmacies from January 1, 2006 through January 31, 2007.

Historically, AmerisourceBergen has proactively cooperated with the DEA in preventing diversion of hydrocodone and other controlled substances, and will fully cooperate with the agency in resolving the temporary suspension.

The Company has a diversion program and a DEA-approved suspicious-order monitoring program in place to identify customers who are suspected of inappropriately selling products sold to them by AmerisourceBergen. All of the Orlando Distribution Center's DEA audits, the most recent within the last year, were passed with no deficiencies found. AmerisourceBergen is not doing business with any of the four customers cited by the DEA, and all of the pharmacies mentioned by the agency held active DEA licenses to sell controlled substances at the time AmerisourceBergen sold product to them.
