Cadmus Acquires International Development Consultancy Nathan

Longstanding International Development Leader Will Form New Operating Division, More Than Doubling Cadmus’ U.S. Federal Contracting Business

ARLINGTON, Va., February 16, 2023—Cadmus, a leading provider of technical and strategic expertise to governments, energy utilities, and private sector companies worldwide, announces its acquisition of Nathan Associates, Inc. (Nathan), an international economic and analytics consulting firm that works with government and commercial clients around the globe to deliver practical solutions and achieve lasting results.

With Nathan’s competitive edge of 75 years of technical expertise and advisory services in more than 100 countries, and Cadmus’ broad domain expertise within its established markets and mature operational infrastructure, this transaction will yield access to new markets and fuel greater impact for clients globally.

“I’m very excited about what Cadmus and our new colleagues from Nathan are capable of accomplishing together,” said Cadmus President and CEO Ian Kline. “Moving forward, we will continue to expand our presence and enhance our support for clients around the globe with a team that shares our vision, commitment to technical excellence, and drive to make an impact.”

Under the new structure, Nathan will form Cadmus’ new International Development Division led by Senior Vice President of International Development Jeffrey Singer. Current Nathan President and CEO Susan Chodakewitz will become Executive Vice President of Public Sector Strategy, serving an essential company-wide leadership role to develop and execute Cadmus’ ambitious public sector growth strategy in the U.S. and globally.

The addition of Nathan to Cadmus more than doubles Cadmus’ U.S. federal contracting business and strengthens its competitiveness as a USAID prime contractor and with other development organizations in the U.S. and abroad. In addition, Nathan will gain access to contract vehicles held by Cadmus that align well with its capabilities and open opportunities to capture new business.

“As we consider expanding our work and increasing our impact in the future, I believe that this combined new entity possesses the people, expertise, and experience to provide enhanced client support and increased opportunities for our employees to thrive,” said Chodakewitz.
