CELESTICA INC 8-K

What Happened Celestica Inc. (CLS) filed an 8-K on March 24, 2026, announcing that Board Chair Michael M. Wilson will not stand for re-election and will retire effective immediately prior to the company's 2026 annual meeting of shareholders. In connection with his departure, President and CEO Robert A. Mionis was appointed Chair of the Board and Laurette T. Koellner was appointed Lead Independent Director, both effective immediately prior to the 2026 AGM. The Board also appointed David Reeder as a director effective May 1, 2026.

Key Details

• Michael M. Wilson informed the company on March 24, 2026 that he will retire consistent with the company's director retirement policy; no disagreement with the company was reported.
• Robert A. Mionis (President & CEO) will serve as Board Chair; Laurette T. Koellner will serve as Lead Independent Director, effective immediately before the 2026 AGM.
• David Reeder joins the Board effective May 1, 2026, and is deemed independent under Canadian securities laws and NYSE rules; he will serve on the Audit Committee, Human Resources & Compensation Committee, and Nominating & Corporate Governance Committee.
• Reeder’s background: current President & CEO and board member of Entegris, Inc.; former CFO of Chewy (2024–2025) and GlobalFoundries (2020–2024, oversaw 2021 IPO); prior executive roles at Tower Hill, Lexmark, EFI, Cisco, Broadcom and Texas Instruments; served on Alphawave’s board (2023–2025). No related-party transactions or special arrangements were reported. Compensation will follow the company’s director compensation policies.

Why It Matters These changes update Celestica’s board leadership and maintain independent oversight: the CEO will also chair the Board while a separate Lead Independent Director has been named, and a seasoned industry executive (David Reeder) is joining key governance committees. For investors, this is a governance and leadership development—important to monitor for any future commentary from the company about strategic direction or governance updates, but the filing notes the change is a planned retirement under company policy and not due to disputes. Exhibit 99.1 (press release) was attached to the filing.
