In June 2011, the boards that led Highmark Inc. and West Penn Allegheny Health System announced a “capital partnership” in which Highmark would invest $475 million in WPAHS, including an upfront $50 million payment that kept the doors open at West Penn Hospital. In 2013, the proposed acquisition became official. West Penn Allegheny Health System continues to exist as a legal entity, but as of 2013 it has been fully absorbed into the larger Allegheny Health Network, which is owned by parent company Highmark Health.
