VALLEY FORGE, Pa. -- AmerisourceBergen Corporation (NYSE:ABC) today announced a more streamlined organizational structure designed to drive increased efficiency and effectiveness and better position the Company to continue to achieve its long-term financial goals.

David Yost, AmerisourceBergen President and Chief Executive Officer. "It is with that singular focus that we are further integrating our organization."

The organizational changes, effective immediately are as follows:

* Michael D. DiCandilo, Executive Vice President and Chief Financial Officer of AmerisourceBergen, expands his responsibilities with the added position of Chief Operating Officer for AmerisourceBergen Drug Corporation (ABDC) and continues to report directly to Yost. The ABDC functions reporting to DiCandilo in his new role as ABDC Chief Operating Officer are Supply Chain Management; Operations, including the distribution network; and Financial Operations, which previously reported to him.

Said Yost, "Terry has made an extraordinary contribution to AmerisourceBergen. He played a key role in the integration of the legacy companies to create AmerisourceBergen; successfully provided leadership for ABDC after integration was well on its way to successful completion; and provided critical leadership to the launch of our Business Transformation effort. I will miss Terry both professionally and personally."

Murphy, Senior Vice President and Chief Information Officer, expands his responsibilities to include the leadership of Business Transformation, the Company's multi-year process improvement project, which includes design of an ERP (Enterprise Resource Planning) system for ABDC and the Corporation.
