PETALUMA, CA - July 8, 2014 - Calix, Inc. (NYSE: CALX) today announced the addition of telecommunications industry veteran Christopher J. Bowick to the company's Board of Directors, replacing Michael Ashby who served on the company’s board of directors and retired as the company’s CFO in February 2014. A seasoned executive with over 25 years of cable television industry experience, Bowick has held leadership positions at Cox Communications, Charter Communications, Jones Intercable, and Scientific-Atlanta.

“Calix has proven to be a leader in the broadband access market in North America over the course of the last decade through innovation, vision, and execution," said Bowick. "The company is well positioned to capitalize on the emerging convergence of cable and telecom markets as service providers increasingly turn to fiber based solutions to deliver the speed and quality of service being demanded by both business and residential consumers. I am looking forward to joining the Calix team as the company executes on its next phase of growth.”

Following Bowick’s 2009 retirement from Cox, where he had served as senior vice president of engineering and the chief technical officer (CTO) for 11 years, he founded and currently serves as president of The Bowick Group, LLC, who provide technology, product, business, and executive development advice and counsel to clients in the cable television and telecommunications industries. Bowick currently serves on the Boards of Directors of ViXS Systems and Minerva Networks.

During 2011, Bowick served as an Interim CTO of Charter Communications, Inc. while leading Charter’s search for a permanent CTO. He earned an M.B.A. from the University of Colorado in 1997, and a bachelor’s degree in electrical engineering from the Georgia Institute of Technology in 1977.

"Service providers of all kinds, traditional telecoms operators, cable companies, wireless providers, municipalities, and other new entrants, are all grappling with the access network implications of content moving to the cloud and with the proliferation of broadband-enabled devices," said Carl Russo, Calix president and CEO. "Our Unified Access architecture has been meeting this challenge for many years. Chris's extensive knowledge and experience in leadership roles at communications technology companies and service providers is a tremendous asset for Calix as we help our customers continue to adapt, transform, and grow.”
