Fairfax, Virginia, April 28, 2021

CGI (NYSE: GIB) (TSX: GIB.A) today announced its intent to acquire Sense Corp, a professional services firm focused on digital systems integration and consulting for state and local government and commercial clients. This merger further expands CGI’s footprint in Austin, Dallas, Houston, and St. Louis and grows CGI’s digital and cloud solution capabilities. The two companies signed an agreement to proceed with the transaction, which is expected to close in early May.

Sense Corp brings approximately 300 highly skilled consultants to CGI, and enhances and accelerates CGI’s position as a leading provider of comprehensive, scalable and sustainable IT and business consulting services to meet growing demand in both the state and local government and commercial sectors.

“This transaction is consistent with CGI’s well-articulated build and buy strategy to invest in both transformational and niche acquisitions that will spur future growth and expand coverage in targeted metro markets,” said Tim Hurlebaus, CGI President of U.S. Commercial and State Government Operations. “By merging forces with Sense Corp, it will have a significant positive impact on our U.S. Texas and Midwest operations while acting as a catalyst for future organic growth for the overall U.S. business.”

“One of the most closely scrutinized aspects of any merger is the alignment of culture. CGI and Sense Corp share a commitment to help clients by providing valuable insights and working together to deliver positive outcomes,” said Jody Beasley, CGI Senior Vice-President, Consulting Services and U.S. Texas Business Unit Leader. “Sense Corp brings both unique local relationships and deep industry experience to the CGI global platform.”

In the U.S., CGI has nearly 13,000 consultants and professionals across 80 offices that are organized through a client proximity model, supported by the depth of its international presence, range of services, and insights to deliver value locally.
