FAIRFAX, Va. – ICF International (NASDAQ:ICFI), a leading provider of consulting services and technology solutions to government and commercial clients, announced that it has named Ronald P. Vargo to the position of executive vice president and chief financial officer effective April 1, 2010. He will replace Alan Stewart, currently executive vice president and chief financial officer, who previously announced that he would retire from the company at the end of March 2010.

Mr. Vargo, 55, brings 30 years of experience as a financial and business executive to ICF International. Most recently, he was executive vice president and chief financial officer of EDS, a $22 billion global technology services company that was acquired by Hewlett-Packard Company in 2008. In his position at EDS, Mr. Vargo was responsible for the company’s overall financial plans, policies, and accounting practices and oversaw EDS’s global finance organization.

Commenting on this appointment, ICF International Chairman and Chief Executive Officer Sudhakar Kesavan said, “Adding a leader of Ron Vargo’s caliber and range to our executive management team is an important element of our growth strategy. His global experience in finance, business development, and government and commercial services enhances our ability to continue to post strong organic growth and to serve as an effective platform for additional acquisitions.”

Prior to joining EDS as vice president and treasurer in 2004, Mr. Vargo spent 12 years with TRW, a $17 billion multi-industry global company, serving as vice president and treasurer and vice president of strategic planning and business development during his tenure. Before that, Mr. Vargo had a 10-year career at The Standard Oil Company and British Petroleum PLC, where he held several finance and line positions. Mr. Vargo graduated from Dartmouth College and received an MBA in Finance and General Management from Stanford University.

Mr. Vargo currently serves on the Board of Directors of Ferro Corporation, a publicly traded, leading global supplier of technology-based performance materials for manufacturers, headquartered in Cleveland.
