CHARTERED REALIGNS SENIOR MANAGEMENT ROLES TO LEAD NEXT PHASE OF GROWTH

SINGAPORE – April 13, 2007 – Chartered Semiconductor Manufacturing (Nasdaq: CHRT and SGX-ST: Chartered), one of the world’s top dedicated foundries, today announced realignment of certain senior management roles, aimed at driving further customer service and operational excellence and positioning the company for the next phase of growth. The changes are effective immediately.

As part of the realignment, Kay Chai “KC” Ang becomes senior vice president of worldwide sales and marketing, and Dr. Simon Yang assumes the duties of senior vice president of fab operations, in addition to his current role as chief technology officer (CTO). Mike Rekuc becomes president of the Americas region, and Dominique Simon is appointed to a newly created position of vice president of business development and global accounts.

“With the growth and evolution of the semiconductor and foundry markets, we recognize that our customers need tighter integration between technology, customer engagement and manufacturing in order to better address their time-to-market demands. With the changes announced today, I believe Chartered will be in a better position to anticipate and respond to evolving customers demands, thus positioning the company for its next phase of growth,” said Chia Song Hwee, president & CEO of Chartered.

With today’s realignment of roles, all customer service, sales and marketing, and strategic alliances activities will be under Ang’s leadership. Ang most recently served as senior vice president of fab operations. In assuming the duties of senior vice president of fab operations, Yang has responsibility for manufacturing strategy and operational excellence across all fabs, and he will continue with his current responsibilities as CTO. Both Ang and Yang will continue to report directly to the president & CEO.

After spending nearly four years in Singapore overseeing the execution of the company’s customer strategy during a critical phase in Chartered’s transformation, Rekuc will return to Silicon Valley to assume his previous role heading the company’s largest region. Meanwhile, Dominique Simon will build on his valuable experience in the US Region to focus on broadening the company’s customer base in targeted areas and ensuring tighter alignment with major global accounts in his new position. Rekuc and Dominique Simon will report directly to Ang.
