PART II — RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Sanmina Corporation (the “Company”) has determined that it is unable to file its Quarterly Report on Form 10-Q for the fiscal quarter ended April 1, 2023 (the “Form 10-Q”) by May 11, 2023, the original due date for such filing, without unreasonable effort or expense due to the circumstances described below.

As previously announced in the Form 8-K filed by the Company with the Securities and Exchange Commission (the “SEC”) on May 11, 2023 (the “Form 8-K”), during the preparation of its unaudited consolidated financial statements for the fiscal quarter ended April 1, 2023, the Company determined that certain personnel in a division within the Company’s Components, Products and Services business had failed to properly substantiate and update cost estimates for materials and other costs over the life of certain contracts. As a result, the Company conducted an independent investigation under the direction of the Audit Committee of the Company’s Board of Directors (the “Audit Committee”). Primarily due to the findings of the independent investigation, revenue was over/(understated) by approximately $10.2 million, $18.3 million, ($29.1 million), and $5.6 million, and GAAP earnings per share was over/(understated) by approximately $0.09, $0.29, $0.25, and ($0.06) in the fiscal years ended October 3, 2020, October 2, 2021 and October 1, 2022, and the first fiscal quarter ended December 31, 2022, respectively (collectively, the “Affected Periods”). The associated interim periods for the Affected Periods were also impacted. Because these misstatements are material to the Affected Periods compared to the previously reported results of operations for such periods, on May 10, 2023, the Audit Committee concluded that the consolidated financial statements for the Affected Periods included in the Company’s Annual Reports on Form 10-K for the fiscal years ended October 3, 2020, October 2, 2021 and October 1, 2022 and the unaudited condensed consolidated financial statements included in the Company’s Quarterly Reports on Form 10-Q for the quarterly fiscal periods included in such fiscal years and for the first fiscal quarter ended December 31, 2022, should no longer be relied upon.

The Company is working to complete and file the restated consolidated financial statements for the Affected Periods on Form 10-K/A for the fiscal year ended October 1, 2022 and Form 10-Q/A for the first fiscal quarter ended December 31, 2022 and to file the Form 10-Q with the SEC as promptly as possible. However, due to the time and effort required to complete the preparation of the restated financial statements and restated financial information, the Company was unable, without unreasonable effort or expense, to complete and file the Form 10-Q within the prescribed time period. Please refer to Item 4.02 of the Form 8-K for additional details.

PART IV — OTHER INFORMATION

The Company’s unaudited earnings results for the fiscal quarter ended April 1, 2023 and the fiscal quarter ended April 2, 2022 are included in the press release furnished under Item 2.02 of the Form 8-K.

Cautionary Note Regarding Forward Looking Statements:

This Form 12b-25 contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements can be identified by the use of forward-looking terminology such as “expects,” “believes,” “estimates,” “projects,” “intends,” “plans,” “seeks,” “may,” “will,” “should” or “anticipates” or the negative or other variations of these or similar words. Although the Company believes that its expectations are based on reasonable assumptions within the bounds of the Company’s knowledge of its business, there can be no assurance that actual results, including the impact of the restatement, will not differ materially from our expectations. Meaningful factors that could cause actual results to differ from expectations include, but are not limited to, risks relating to the final impact of the restatement on the Company’s financial statements; the impact of the restatement on the Company’s evaluation of the effectiveness of its internal control over financial reporting and disclosure controls and procedures; delays in the preparation of the financial statements; the risk that additional information will come to light during the course of the independent investigation that alters the scope or magnitude of the restatement; the risk that the amounts ultimately recovered from customers are less than the amount of cost overruns that the Company is required to record in its financial statements; and the risk that the Company will be unable to obtain, if needed, any required waivers under its credit agreement with respect to a significant delay in filing periodic reports with the SEC, which could affect its liquidity. The Company does not intend to update publicly any forward-looking statements except as required by law. In light of these risks, uncertainties and assumptions, the forward-looking events discussed in this Form 12b-25 may not occur.
