KEY Tronic Corp

Key Tronic Corporation (the “Company”) is filing this Notification of Late Filing on Form 12b-25 (the “Form 12b-25”) with respect to its Annual Report on Form 10-K for the year ended June 29, 2024 (the “Form 10-K”) because the Company was unable to timely file its Form 10-K without unreasonable effort and expense, as further described below. The Company requires additional time to finalize its financial statements and related disclosure for inclusion in the Form 10-K due to a number of factors. Specifically, the Company became aware of a material weakness in its internal controls related to an aggregation of issues including classification of the recovery of material price variances on the income statement, and estimates for current expected credit losses. The Company and its independent auditor are analyzing the accounting and disclosure requirements that may apply to each of these items, and the Company anticipates that restatement of prior periods may be required. Finance staff turnover and management transitions have additionally contributed to the delay. As a result of the foregoing, the Company requires additional time to complete its year-end reporting procedures and to provide its independent auditor with the necessary information in order for the auditor to complete its audit procedures relating to the audit of the Company’s financial statements for the year ended June 29, 2024

Key Tronic Corporation (the “Company”) is unable to file its Quarterly Report on Form 10-Q for the quarter ended April 3, 2021 by the prescribed due date without unreasonable effort or expense. As previously disclosed, the Audit Committee of the Company’s Board of Directors (the “Audit Committee”) is conducting an internal investigation related to a notification from an employee regarding irregularities of the classification of inventory at a production facility. The investigation is ongoing, and the Audit Committee continues to work diligently with independent counsel and advisors to complete the investigation as soon as possible. As a result, the Company has not finalized its financial statements or its assessment of the effectiveness of its disclosure controls and procedures and any impact on its internal control over financial reporting relating to the Form 10-Q for the quarter ended December 26, 2020, as well as the Form 10-Q for the quarter ended April 3, 2021. The Company is not in a position to file its Quarterly Reports on Form 10-Q at this stage of the internal investigation and as the Company’s independent public accounting firm undertakes its required procedures. The Company expects that it will finalize its financial statements and review procedures for the second and third quarters of fiscal 2021 and file the related Quarterly Reports on Form 10-Q as soon as practicable after the conclusion of the internal investigation.
