November 4, 2009 “Together we can do more than any of us can do individually.” Ann Vezina, Group President ACS Enterprise Solutions and Services While change is in the air, each of our individual efforts will collectively shape the future of our company just as they have propelled ACS along its impressive journey so far. It’s this unwavering commitment of many that will help two powerhouses – ACS and Xerox – come together to create something greater than either could have alone. It may be many weeks before ACS and Xerox join forces. But that’s an eternity when you consider what we accomplish on behalf of our clients every day. How can we be the future, now? Quite simply by focusing on our ACS goals and values – working together and being responsive to our customers and teammates. 1988 ACS Founded 1990 1992 1994 ACS Goes Public 1996 ACS Lists on New York Stock Exchange 1998 2000 2002 2004 2006 2008 ACS Celebrates 20th Anniversary 2010 ACS Teams up with Xerox BE THE FUTURE.
