CELESTICA INC

Canadian Defined Contribution Plans

Mr. Chawla participates in the Corporation’s registered pension plan for Canadian employees (the “Canadian Pension Plan”) which is a defined contribution plan. The Canadian Pension Plan allows employees to choose how the Corporation’s contributions are invested on their behalf within a range of investment options provided by third-party fund managers. Retirement benefits depend upon the performance of the investment options chosen. Mr. Chawla also participates in an unregistered supplementary pension plan (the “Canadian Supplementary Plan”). This is also a defined contribution plan through which the Corporation provides an annual contribution of an amount equal to the difference between (i) the maximum annual contribution limit as determined in accordance with the formula set out in the Canadian Pension Plan and with the Canada Revenue Agency rules and (ii) 8% of the total base salary and paid annual incentives. Notional accounts are maintained for each participant in the Canadian Supplementary Plan. Participants are entitled to select from among the investment options available in the Canadian Pension Plan for the purpose of determining the return on their Canadian Supplementary Plan notional accounts.

U.S. Defined Contribution Plans

Messrs. Mionis, Phillips, Cooper and Etienvre participate in the Corporation’s U.S. retirement plans comprised of two defined contribution retirement programs, one of which qualifies as a deferred salary arrangement under section 401(k) of the U.S. Internal Revenue Code (the “401(k) Plan”). Under the 401(k) Plan, participating employees may defer 100% of their pre-tax earnings subject to any statutory limitations. The Corporation may make contributions for the benefit of eligible employees. The 401(k) Plan allows employees to choose how their account balances are invested on their behalf within a range of investment options provided by third-party fund managers. The Corporation contributes: (i) 3% of eligible compensation for the participant, and (ii) up to an additional 3% of eligible compensation by matching 50% of the first 6% contributed by the participant. The maximum contribution to the 401(k) Plan, based on the Internal Revenue Code rules and the 401(k) Plan formula for 2025 was $23,500 (plus an additional $7,500 for an individual over the age of 50). Messrs. Mionis, Phillips, Cooper and Etienvre also participate in a supplementary retirement plan that is also a defined contribution plan (the “U.S. Supplementary Plan”). Under the U.S. Supplementary Plan, the Corporation contributes to the participant an annual amount equal to the difference between 8% of the participant’s salary and paid incentive and the amount that Celestica would contribute to the 401(k) Plan assuming the participant contributes the amount required to receive the matching 50% contribution by Celestica. A notional account is maintained for Messrs. Mionis, Phillips, Cooper and Etienvre, and they are entitled to select from among the investment options available in the 401(k) Plan for the purpose of determining the return on their notional accounts.
