Accounting Policies [Abstract] |
Principles of Consolidation | Principles of Consolidation The interim condensed consolidated financial statements include the Company’s assets, liabilities, revenues, and expenses, as well as the assets, liabilities, revenues, and expenses of subsidiaries in which it has a controlling financial interest, SkyWater Technology Foundry, Inc. (“SkyWater Technology Foundry”), SkyWater Federal, LLC (“SkyWater Federal”), SkyWater Florida, Inc. (“SkyWater Florida”), Spansion Fab 25, LLC (“Fab 25”) and Oxbow Realty Partners, LLC (“Oxbow Realty”), a variable interest entity (“VIE”) for which SkyWater is the primary beneficiary and an affiliate of the Company’s principal stockholder. The Company reports noncontrolling interests for amounts that are attributable to ownership interests other than the Company’s common shareholders. All intercompany accounts and transactions have been eliminated in consolidation.
Liquidity and Cash Requirements | Liquidity and Cash Requirements The accompanying interim condensed consolidated financial statements have been prepared on the basis of the realization of assets and the satisfaction of liabilities and commitments in the normal course of business and do not include any adjustments to the recoverability and classifications of recorded assets and liabilities as a result of uncertainties. For the three- and six-month periods ended June 28, 2026, the Company incurred net losses attributable to SkyWater Technology, Inc. of $6,378 and $18,686, respectively. For the three- and six-month periods ended June 29, 2025, the Company incurred net losses attributable to SkyWater Technology, Inc. of $9,978 and $17,323, respectively. As of June 28, 2026 and December 28, 2025, the Company had cash and cash equivalents of $12,582 and $23,224, respectively. SkyWater’s ability to execute its operating strategy is dependent on its ability to maintain liquidity and continue to access capital through the Revolver (as defined in Note 7 – Debt), and other sources of financing. The current business plans indicate that the Company maintains sufficient liquidity to continue its operations and maintain compliance with financial covenants for the next twelve months from the date the consolidated financial statements are issued. As a result of amendments made on June 30, 2025, the Revolver matures on June 30, 2030 and provides for a maximum revolving facility amount of $350,000. Based upon SkyWater’s operational forecasts, cash and cash equivalents on hand, and available borrowings on the Revolver, management believes SkyWater will have sufficient liquidity to fund its operations for the next twelve months from the date these condensed consolidated financial statements are issued.
Use of Estimates | Use of Estimates The preparation of the interim condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the interim condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods then ended. Management evaluates these estimates and judgments on an ongoing basis and bases its estimates on experience, current and expected future conditions, third-party evaluations, and various other assumptions that management believes are reasonable under the circumstances. Actual results could differ from those estimates.
Net Loss Per Share | Net Loss Per Share Basic net loss per common share is calculated by dividing the net loss attributable to SkyWater Technology, Inc. by the weighted-average number of shares outstanding during the reporting periods, without consideration for potentially dilutive securities. Diluted net loss per common share is computed by dividing the net loss attributable to SkyWater Technology, Inc. by the weighted-average number of shares and potentially dilutive securities outstanding during the reporting periods determined using the treasury-stock method. Because the Company reported a net loss attributable to SkyWater Technology, Inc. for the three- and six-month periods ended June 28, 2026 and June 29, 2025, the number of shares used to calculate diluted net loss per common share is the same as the number of shares used to calculate basic net loss per common share because the potentially dilutive shares would have been anti-dilutive if included in the calculation. For the three- and six- month periods ended June 28, 2026, there were restricted stock units and stock options totaling 2,090,546 and 2,105,615, respectively, excluded from the computation of diluted weighted-average shares outstanding because their inclusion would have been anti-dilutive. For the three- and six-month periods ended June 29, 2025, there were restricted stock units and stock options totaling 1,843,813 and 1,410,985, respectively, excluded from the computation of diluted weighted-average shares outstanding because their inclusion would have been anti-dilutive.
Recently Issued Accounting Standards Not Yet Adopted | Recently Issued Accounting Standards Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (“ASU 2023-09”). The amendments in this update improve existing income tax disclosures, notably with respect to the income tax rate reconciliation and income taxes paid disclosures, and are effective for annual periods beginning after December 15, 2025. As an emerging growth company, SkyWater will adopt the amendments in ASU 2023-09 for its fiscal year ending January 3, 2027. The Company is evaluating the impacts of the amendments on its consolidated financial statements and the accompanying notes to the financial statements. In November 2024, the FASB issued ASU No. 2024-03, Income Statement — Reporting Comprehensive Income—Expense Disaggregation Disclosures (“ASU 2024-03”). The amendments in this update require disaggregated disclosure of income statement expenses for public business entities. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. The amendments in ASU 2024-03 are effective for annual periods beginning after December 15, 2026. SkyWater will adopt the amendments in this update for its fiscal year ending January 2, 2028. The Company is evaluating the impacts of the amendments on its consolidated financial statements and the accompanying notes to the financial statements. In July 2025, the FASB issued ASU No. 2025-05, Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”). The amendments in this update provide registrants with a practical expedient in its application of FASB Accounting Standards Codification (“ASC”) Topic 326, Financial Instruments – Credit Losses, and allow it to assume that conditions as of the balance sheet date will remain the same over the future life of the asset when estimating potential collections and losses. The amendment in ASU 2025-05 will become effective for the Company’s fiscal year ended January 3, 2027. SkyWater is currently evaluating whether it will adopt the practical expedient introduced by ASU 2025-05. In September 2025, the FASB issued ASU No. 2025-06, Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). The amendments in this update introduce a more principles-based framework to the capitalization of software intended for internal use focused on management’s authorization and commitment to fund a development project and the probability of whether the project will be completed and used for its intended function. The amendment in ASU 2025-06 will become effective for the Company’s fiscal year ended December 31, 2028. SkyWater is currently evaluating the impacts of the amendments on its consolidated financial statements and the accompanying notes to the financial statements. In December 2025, the FASB issued ASU No. 2025-10, Accounting for Government Grants Received by Business Entities (“ASU 2025-10”). The amendments in this update establish guidance on the recognition, measurement and presentation of government grants received by business entities. The amendments in ASU 2025-10 will become effective for the Company’s fiscal year ended December 30, 2029. The Company is evaluating the impacts of the amendments on its consolidated financial statements and the accompanying notes to the financial statements. In December 2025, the FASB issued ASU No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”). The amendments in this update clarify the interim reporting requirements of ASC Topic 270, Interim Reporting, and more clearly specifies what disclosures are required for an interim reporting period. The amendments in ASU 2025-11 will become effective during the Company’s fiscal year ended December 31, 2028. The Company is evaluating the impacts of the amendments on its consolidated financial statements and the accompanying notes to the financial statements.
