Sulzbach, Germany, August 31, 2015

ArcelorMittal Bremen, a subsidiary of ArcelorMittal, the world's largest steel producer, has renewed its partnership with CGI (NYSE: GIB) (TSX: GIB.A).

ArcelorMittal Bremen outsourced its IT to CGI five years ago, and, since then, CGI has managed the company’s two data centers in Bremen, provided IT infrastructure support, and maintained all applications predominantly developed by ArcelorMittal Bremen, as well as other warehousing and automated production control systems. In addition, CGI provides field service support for approximately 2,000 Windows end-user systems.

CGI’s scope of activities for ArcelorMittal Bremen has expanded considerably over the course of the engagement. CGI was given, for example, responsibility for an additional 180 production control systems. In fact, the contract volume has doubled in size.

"Many of our systems are production critical, and a failure can lead to downtime and high follow-up costs,” said Claus Otten, head of automation processes for ArcelorMittal Bremen. “CGI operates these systems flawlessly, ensuring their consistent availability.”

"Nothing demonstrates our commitment to ArcelorMittal Bremen better than the extension of this collaboration," said Tobias Jänich, CGI Vice-President, Outsourcing, Germany. "Today we take on more tasks for ArcelorMittal Bremen, and, more importantly, we take over critical tasks. We are honored to be able to continue this very successful partnership.”
