**PART III — NARRATIVE** 

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

SkyWater Technology, Inc. (the "Company") has determined that it will not be able to file its Quarterly Report on Form 10-Q for the quarter ended September 28, 2025 (the "Form 10-Q") by November 10, 2025, the original due date for such filing, without unreasonable effort or expense because the Company requires additional time to prepare and review its financial statements to correct certain immaterial errors arising from prior years and to ensure adequate disclosure of these errors in the financial information required to be included in the Form 10-Q. During the preparation of the consolidated financial statements for the fiscal quarter ended September 28, 2025, the Company identified immaterial errors in its previously issued financial statements for its 2022 and 2023 fiscal years ended January 1, 2023 and December 31, 2023, respectively. The errors related to overstatements of Advanced Technology Services (ATS) development revenues for a cumulative total of $1.970 million. The Company determined that the errors were not material to either its 2022 or 2023 fiscal year consolidated financial statements and that the errors were not material in the aggregate, and thus, the Company is correcting the impacted fiscal years as immaterial corrections of errors. As a result, the Company is revising the financial information for each of its 2022 and 2023 fiscal years in its interim consolidated financial statements as of and for the three- and nine-month fiscal periods ended September 28, 2025 by increasing the beginning accumulated deficit balance as of December 30, 2024 by $1.970 million and decreasing accounts receivable for the same amount. These errors relate to the previously disclosed material weakness in our revenue accounting process. The Company expects to file the Form 10-Q within the five-calendar-day extension period provided under Rule 12b-25 of the Securities Exchange Act of 1934, as amended.
