I am honored to take on this additional responsibility and look forward to working closely with Laurette and the rest of the Board to execute our long-term strategy." "Mike has set an outstanding example of principled leadership and, as Lead Independent Director, I will work to ensure that the Board continues with its commitment to strong corporate governance," continued Ms. Koellner.

"We intend to execute a planned and orderly succession," said Mr. Wilson. "Rob's deep experience and strategic foresight have been vital to the Company's success, and he is an ideal choice to lead the Board in partnership with Laurette, whose deep governance expertise and industry knowledge make her ideally suited for this important role. The Board has full confidence that Rob's and Laurette's visionary leadership will be instrumental in driving the next phase of our growth strategy."

Celestica is pleased to also announce the appointment of David Reeder to the Board effective May 1, 2026.
