On April 27, 2026, Celestica Inc. (the “Company”) amended its existing senior credit agreement (the “April 2026 Amendment”) with Bank of America, N.A., as Administrative Agent, and the lenders party thereto to: (1) increase the commitments under the Company’s revolving credit facility (“Revolver”) from $750.0 million to $1,750.0 million; (2) refinance the Company’s existing term A loan facility (“Term A Loan,” $228.1 million outstanding borrowings at March 31, 2026) into a new $250.0 million term A loan facility (“New Term A Loan”); and (3) extend the maturity of the Revolver and the New Term A Loan from June 2029 to April 2031. The New Term A Loan was fully drawn at closing of the April 2026 Amendment. The proceeds of the New Term A Loan were used to repay all amounts outstanding under the refinanced Term A Loan and certain fees and expenses related to the April 2026 Amendment, with any remaining proceeds to be used for general corporate purposes. Amounts drawn under the Revolver are permitted to be used for general corporate purposes.

Under the credit agreement as amended by the April 2026 Amendment (the “Amended Credit Facility”), outstanding borrowings under the Revolver bear interest at varying rates (as specified therein), plus a margin ranging from 1.00% — 1.75%, or from 0.05% — 0.75%, in each case depending on the currency of the borrowings, the rate the Company selects, and the corporate rating of the Company (as defined in the Amended Credit Facility). The current margin applicable to post-closing U.S. dollar Revolver borrowings bearing interest based on the term Secured Overnight Financing Rate (“Term SOFR”) is 1.50%. Commitment fees on undrawn funds available under the Revolver range between 0.100% to 0.275%, depending on the corporate rating of the Company (as defined in the Amended Credit Facility). The New Term A Loan bears interest at varying rates (as specified in the Amended Credit Facility), plus a margin ranging from 1.00% — 1.75%, or from 0.05% — 0.75%, in each case depending on the rate the Company selects and the corporate rating of the Company (as defined in the Amended Credit Facility). The current margin applicable to the New Term A Loan bearing interest based on Term SOFR is 1.50%.

The April 2026 Amendment does not materially modify the circumstances under which obligations under the Amended Credit Facility may be accelerated. As amended, amounts outstanding may be accelerated upon the occurrence of customary events of default, including, among others, payment default, covenant breach and insolvency. The April 2026 Amendment does not introduce any new provisions under the Amended Credit Facility that would permit lenders to require increased payments or additional collateral.

The Amended Credit Facility was provided by a syndicate of lenders, with Bank of America, N.A. acting as Administrative Agent. BofA Securities, Inc. acted as Left Lead Arranger and Left Lead Bookrunner. Canadian Imperial Bank of Commerce and CIBC World Market Corp., Crédit Agricole Corporate and Investment Bank (Canada Branch) and TD Securities acted as Joint Lead Arrangers, Joint Bookrunners and Co-Syndication Agents. BNP Paribas Securities Corp. and Royal Bank of Canada acted as Co-Documentation Agents.

The foregoing description of the April 2026 Amendment and the Amended Credit Facility does not purport to be complete and is qualified in its entirety by reference to the full text of the April 2026 Amendment, a copy of which is attached hereto as Exhibit 10.1 and incorporated herein by reference.

The disclosures contained in “Item 1.01. Entry into a Material Definitive Agreement” of this Current Report on Form 8-K are incorporated into this Item 2.03 by reference.
