Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Organization	Note 1. Business and Organization Shimmick Corporation ("Shimmick", the “Company”) was founded in 1990 in California and operated as a regional infrastructure construction contractor throughout California for nearly 30 years. In 2017, AECOM acquired Shimmick and consolidated it with its existing construction services, which included former legacy construction operations from Morrison Knudsen, Washington Group International, and others. In January 2021, we consummated the AECOM Sale Transactions and began operating as an independent company under new private ownership (the "AECOM Sale Transactions"). The accompanying condensed consolidated financial statements include the accounts of Shimmick Corporation and its subsidiaries (“Shimmick”, “we”, “our”, “us”, “its” or the “Company”), unless otherwise indicated. On September 12, 2023, the Company changed its name from SCCI National Holdings, Inc. to Shimmick Corporation. On November 16, 2023, Shimmick completed its initial public offering of 3,575,000 shares of common stock at a price to the public of $ 7.00 per share (the "IPO"). The net proceeds to Shimmick from the IPO were approximately $ 19 million after deducting underwriting discounts and commissions of $ 2 million and other offering expenses of $ 4 million. Shimmick’s common stock began trading on the NASDAQ Global Market on November 14, 2023.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Note 2. Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”), and in conformity with the rules and regulations of the Securities and Exchange Commission. The information furnished reflects all adjustments, consisting of normal recurring adjustments, that are, in the opinion of management, necessary for a fair presentation of the results of operations, cash flows and financial position for the interim periods presented. A statement of comprehensive income is not presented as the Company’s results of operations do not contain any items classified as comprehensive income. All intercompany accounts and transactions have been eliminated. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations, although management believes the disclosures are adequate to prevent the information presented from being misleading. The accompanying condensed consolidated interim financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements and notes in our Annual Report on Form 10-K for the fiscal year ended December 29, 2023 ("Form 10-K"). Because of the seasonal nature of some of the Company's operations, the results of operations for the three and nine months ended September 27, 2024 are not necessarily indicative of the results of operations to be expected for the full fiscal year. Change in Presentation Certain prior period balances in the condensed consolidated balance sheets, statements of operations and statements of cash flows and accompanying notes have been combined, reclassified or rounded to conform to current period presentation. These changes had no impact on net (loss) income, cash flows, assets and liabilities, or equity previously reported. Summary of Significant Accounting Policies Our significant accounting policies are described in more detail in Note 2 - Basis of Presentation and Summary of Significant Accounting Policies of our Form 10-K. Use of Estimates The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts included in the condensed consolidated financial statements and accompanying notes thereto. Actual results could differ from those estimates. Recently Issued Accounting Pronouncements Accounting pronouncements not listed below were assessed and determined to be not applicable or are expected to have minimal impact on the condensed consolidated financial statements. In November 2023, the FASB issued ASU 2023-07 to enhance disclosures of significant expense and segment profitability categories and amounts for reportable business segments. The amendment is effective in interim periods in the fiscal year beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the provisions of the amendments and the impact on its future consolidated financial statements. In December 2023, the FASB issued ASU 2023-09 to improve disclosures and presentation requirements to the transparency of the income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The amendment is effective in interim periods in the fiscal year beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the provisions of the amendments and the impact on its future consolidated financial statements.

Projects that focus on foundation drilling are referred to as "Foundations Projects". Projects that started prior to consummation of the AECOM Sale Transactions are referred to as "Legacy Projects". The following table presents the Company’s revenue disaggregated by Shimmick Projects, Foundations Projects and Legacy Projects: Three Months Ended Nine Months Ended September 27, September 29, September 27, September 29, (In thousands) 2024 2023 2024 2023 Shimmick Projects $ 101,475 $ 109,884 $ 275,457 $ 301,475 Foundations Projects 10,837 11,523 25,931 40,615 Legacy Projects (1) 53,723 54,041 75,296 152,654 Total revenue $ 166,035 $ 175,448 $ 376,684 $ 494,744 (1) Legacy Projects revenue for the three and nine months ended September 27, 2024 reflects a $ 31 million increase to revenue as a result of the GGB Project settlement in which the Company will receive $ 97 million in cash and a contract change order for reduced scope of work of $ 6 million. See Note 12 – Subsequent Events for additional details. Legacy Projects revenue for the nine months ended September 27, 2024 also reflects a reduction to revenue of $ 23 million recorded during the three months ended June 28, 2024 to write off previously recorded contract assets as a result of a settlement of a claim with the United States Army Corps of Engineers. Remaining performance obligations The Company had $ 777 million of remaining performance obligations yet to be satisfied as of September 27, 2024. Our remaining performance obligations have a weighted average life of 2.0 years as of September 27, 2024. Contract Balances The following table provides information about contract assets (also referred to as costs and estimated earnings in excess of billings on uncompleted contracts and retainage receivable) and contract liabilities (also referred to as billings on uncompleted contracts in excess of costs and estimated earnings and forward loss reserve), which include assets and liabilities that are dependent upon future activity: September 27, December 29, 2024 2023 Change (In thousands) Contract assets, current and non-current: Costs and estimated earnings in excess of billings on uncompleted contracts $ 127,518 $ 125,943 $ 1,575 Retainage receivable 49,159 48,316 843 Total contract assets 176,677 174,259 2,418 Contract liabilities, current and non-current: Billings on uncompleted contracts in excess of costs and estimated earnings ( 42,998 ) ( 48,841 ) 5,843 Forward loss reserve ( 54,629 ) ( 70,159 ) 15,530 Total contract liabilities ( 97,627 ) ( 119,000 ) 21,373 Net $ 79,050 $ 55,259 $ 23,791 Contract terms with customers include the timing of billing and payment, which usually differs from the timing of revenue recognition. As a result, the Company carries contract assets and liabilities within the condensed consolidated balance sheets. These contract assets and liabilities are calculated on a contract-by-contract basis and reported on a net basis at the end of each period and are classified as current or non-current. Many of the contracts under which the Company performs work also contain retainage provisions. Retainage refers to that portion of our billings held for payment by the customer pending satisfactory completion of the project. Unless reserved, the Company assumes that all amounts retained by customers under such provisions are fully collectible. These assets and liabilities are reported in the condensed consolidated balance sheets within “Contract assets, current,” “Contract assets, non-current,” “Contract liabilities, current" and “Contract liabilities, non-current." Costs and estimated earnings in excess of billings on uncompleted contracts consists of revenue recognized in excess of billings. Billings on uncompleted contracts in excess of costs and estimated earnings consists of billings in excess of revenue recognized. The Company recognized revenue of $ 41 million during the nine months ended September 27, 2024 that was included in contract liabilities as of December 29, 2023. The Company’s timing of revenue recognition may not be consistent with its rights to bill and collect cash from its clients. Those rights are generally dependent upon advance billing terms, milestone billings based on the completion of certain phases of work or when services are performed. The Company’s accounts receivable represents amounts billed to clients that have yet to be collected and represent an unconditional right to cash from its clients as presented below. September 27, December 29, 2024 2023 (In thousands) Total accounts receivable, gross $ 54,470 $ 55,202 Allowance for credit losses ( 954 ) ( 1,024 ) Accounts receivable, net $ 53,516 $ 54,178 Substantially all contract assets as of September 27, 2024 and December 29, 2023 are expected to be collected within the Company’s estimated operating cycle, except for retainage and claims pertaining to certain contracts. The Company’s operating cycle may extend beyond one year. The Company is in the process of negotiating or awaiting approval of unapproved change orders and claims with its customers. The Company is proceeding with its contractual rights to recoup additional costs incurred from its customers based on completing work associated with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope which resulted in substantial delays and additional costs in completing the work. The Company may take legal action if it and the customer cannot reach a mutually acceptable resolution.

Changes in contract estimates resulted in net decreases in gross margin of $ 44 million for the nine months ended September 27, 2024, primarily due to the United States Army Corps of Engineers settlement and increased forecasted cost to complete loss jobs, partially offset by the GGB Project settlement. Changes in contract estimates resulted in net increases in gross margin of $ 5 million for the three months ended September 29, 2023, primarily due to a change in an outstanding claim. Changes in contract estimates resulted in net decreases in gross margin of $ 10 million for the nine months ended September 29, 2023, primarily due to increased forecasted costs to complete and an agreed upon contract settlement lower than previously estimated, partially offset by increases in gross margin on an outstanding claim.

During the three months ended September 27, 2024, Shimmick completed the sale-leaseback of the Company's equipment yard in Tracy, California. The agreement consummated the sale of the equipment yard for $ 20.5 million and allows us to continue using the property pursuant to a separately executed seven-year lease. The Company received net proceeds of $ 17 million, after adjustments for prepaid rent through February 2026 and related closing costs, which were used to repay borrowings under the Revolving Credit Facility. As a result of the sale, the Company recorded a gain of $ 17 million in Gain on sale of assets within the condensed consolidated statements of operations. During the three months ended September 27, 2024, Shimmick made the strategic decision to enhance the Company’s current enterprise resource planning (ERP) system rather than implementing a new platform which, due to prior capitalized pre-implementation costs and remaining contractual obligations of $ 5 million included in accrued expenses in the accompanying condensed consolidated balance sheets, resulted in a one-time charge of $ 16 million recorded in the three months ended September 27, 2024. The write-off is recorded in ERP pre-implementation asset impairment and associated costs within the condensed consolidated statements of operations.

Debt	Note 6. Debt Total debt outstanding is presented on the condensed consolidated balance sheets as follows: (In thousands) September 27, 2024 December 29, 2023 Credit Facility $ 42,000 $ - Revolving Credit Facility - 29,914 Unamortized debt issuance costs ( 2,097 ) ( 287 ) Long term debt, net $ 39,903 $ 29,627 Revolving Credit Facility On March 27, 2023, we entered into the Revolving Credit Facility with MidCap Financial Services, LLC, which originally provided a total commitment of $ 30 million. The Revolving Credit Facility has been subsequently amended, most recently on September 25, 2024. As amended, the Revolving Credit Facility provides for a total commitment of $ 15 million and bears interest at an annual rate of adjusted term SOFR, subject to a 1.0 % floor, plus 5.50 %. Further, the Revolving Credit Facility is subject to an annual collateral management fee of 0.50 % and an annual unused line fee of 0.50 %. The Revolving Credit Facility includes certain financial operating covenants, including a minimum liquidity requirement of $ 7.5 million. The Revolving Credit Facility matures on December 31, 2024 . The Company is not aware of any instances of noncompliance with the key financial covenants as of September 27, 2024. In the three months ended September 27, 2024, we repaid $ 15 million of the amount outstanding under the Revolving Credit Facility. As of September 27, 2024, no borrowings were outstanding under the Revolving Credit Facility. As of December 29, 2023, $ 30 million was outstanding under the Revolving Credit Facility. Credit Facility On May 20, 2024, the Company, as guarantor, and its wholly-owned subsidiaries as borrowers (“Borrowers”), Alter Domus (US) LLC, as agent, and AECOM and Berkshire Hathaway Specialty Insurance Company (“BHSI”) as lenders, entered into a revolving credit facility (the “Credit Agreement”), which was subsequently amended on September 25, 2024 to, among other things, permit the Company’s concurrent amendment to the Revolving Credit Facility. As amended, the Credit Agreement provides borrowing capacity up to $ 60 million. The obligations under the Credit Agreement bear interest at a per annum rate equal to one month Term SOFR (as defined in the Credit Agreement), subject to a 1.00 % floor, plus 3.50 %. Interest on any outstanding amounts drawn under the Credit Agreement will be payable, in kind or in cash at the election of the Company, on the last day of each month and upon prepayment. The Credit Agreement matures on May 20, 2029 (the “Maturity Date”), and the Borrowers may borrow, repay and reborrow amounts under the Credit Agreement until the Maturity Date. Obligations of the Borrowers under the Credit Agreement are guaranteed by the Company and secured by a lien on substantially all assets of the Company and the Borrowers. The Credit Agreement contains customary affirmative and negative covenants for a transaction of this type, including covenants that limit liens, asset sales and investments, in each case subject to negotiated exceptions and baskets. In addition, the Credit Agreement contains a maximum leverage ratio covenant as tested quarterly commencing with the close of the fourth quarter of 2025. The Credit Agreement also contains representations and warranties and event of default provisions customary for a transaction of this type. The Company is not aware of any instances of noncompliance with financial covenants as of September 27, 2024. As of September 27, 2024, $ 42 million was outstanding under the Credit Facility. The transactions with AECOM also included a mutual release and settlement of certain claims with AECOM and a corresponding agreement to issue 7,745,000 shares of our common shares to AECOM. 5,144,622 of the common shares were issued on May 20, 2024 and issuance of the remaining 2,600,378 shares was completed following shareholder approval on June 26, 2024. Of the total common shares issued, 1,036,949 were held in escrow which resulted in an AECOM voting interest of 19.9 % as of September 27, 2024. The Company recognized a loss of $ 1 million in Other expense, net within the condensed consolidated statements of operations as a result of the share issuance which represented the excess of the $ 13 million fair market value of the common shares at the time of issuance over the $ 12 million carrying value of the contingent consideration liabilities settled with AECOM.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Note 7. Income Taxes We compute the year-to-date income tax provision by applying our estimated annual effective tax rate to our year-to-date pre-tax income and adjust for discrete tax items in the period in which they occur. The effective tax rate was 0 % for the three and nine months ended September 27, 2024 and September 29, 2023. For the nine months ended September 27, 2024, the deferred tax provision resulting from the current year loss is completely offset by the valuation allowance, resulting in zero tax expense. For the nine months ended September 29, 2023, the deferred tax provision resulting from the loss was completely offset by the valuation allowance, resulting in zero tax expense. The Company generally anticipates a zero effective tax rate due to a full valuation allowance. However, the Company may recognize a current tax expense in a specific period if its taxable income, net of available deferred tax assets in that period, exceeds the allowable utilization of tax attributes such as NOL carryforwards. The allowable limitation typically restricts the use of NOL carryforwards to 80 % of taxable income. Deferred Tax Assets and Liabilities We recognize deferred tax assets and liabilities for future tax consequences arising from differences between the carrying amounts of existing assets and liabilities under U.S. GAAP and their respective tax bases, and for net operating loss carryforwards and tax credit carryforwards. We evaluate the recoverability of our deferred tax assets, weighing all positive and negative evidence, and are required to establish or maintain a valuation allowance for these assets if we determine that it is more likely than not that some or all the deferred tax assets will not be realized. As of each reporting date, we consider new evidence, both positive and negative, that could impact our view with regard to the future realization of deferred tax assets. We will maintain our positions with regard to future realization of deferred tax assets, including those with respect to which we continue maintaining valuation allowances, until there is sufficient new evidence to support a change in expectations. Such a change in expectations could arise due to many factors, including those impacting our forecasts of future earnings, as well as changes in the tax laws under which we operate and tax planning. It is not reasonably possible to forecast any such changes at the present time, but it is possible that, should they arise, our view of their effect on the future realization of deferred tax assets may impact materially our condensed consolidated financial statements. After weighing all the evidence, giving more weight to the evidence that was objectively verifiable, a valuation allowance of $ 147 million and $ 124 million as of September 27, 2024 and December 29, 2023, respectively, has been recorded to recognize only the portion of the deferred tax asset that is more likely than not to be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased or if the objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as our projections for growth.

Stock-Based Compensation	Note 8. Stock-Based Compensation On April 12, 2021, the Company’s Board approved the Company’s 2021 Stock Plan (the “2021 Stock Plan”). The 2021 Stock Plan reserves 5,477,200 of the Company’s shares for issuance of incentive instruments, including Incentive Stock Options (“ISOs”), Non-statutory Stock Options, Stock Appreciation Rights, Restricted Stock Awards, and Restricted Stock Unit Awards. ISOs granted under the Plan have a term of 10 years and vest over four years of service. On November 13, 2023, the Company’s Board approved the Shimmick Corporation 2023 Equity Incentive Plan (the “2023 Omnibus Incentive Plan”). 3,729,149 is the maximum aggregate number of shares of Common Stock available under the 2023 Omnibus Incentive Plan (equal to ten percent (10%) of the Company’s Common Stock outstanding immediately following the completion of the Company’s IPO on November 16, 2023 plus (ii) the reserved and authorized shares for awards under the Company’s 2021 Stock Plan that were not granted as of November 13, 2023). The maximum aggregate number of shares of Common Stock that may be issued under the 2023 Omnibus Incentive Plan will automatically increase annually on the first day of each fiscal year, beginning with the 2024 fiscal year in an amount equal to five percent (5%) of Common Stock outstanding on the last day of the immediately preceding fiscal year unless the plan administration determines that a lesser amount should instead be issued. The shares reserved under the 2023 Omnibus Incentive Plan are for issuance of incentive instruments, including stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance units and other share-based awards. Total compensation expense related to stock-based grants was $ 3 millio n and $ 2 million for the nine months ended September 27, 2024 and September 29, 2023, respectively. Unrecognized compensation expense related to stock-based grants to employees of Shimmick outstanding as of September 27, 2024 and September 29, 2023 was $ 7 million and $ 3 million, respectively, to be recognized on a straight-line basis over the awards’ weighted average remaining vesting period of 1 year and 1.6 years, respectively.

Earnings Per Share [Abstract]
Earnings Per Share	Note 9. Earnings Per Share Basic earnings per share (“EPS”) is calculated based on the weighted average shares outstanding during the period. Diluted earnings per share includes the dilutive effect of employee and director stock options and restricted stock units. Stock options are considered dilutive whenever the exercise price is less than the average market price of the stock during the period and antidilutive whenever the exercise price exceeds the average market price of the common stock during the period. All 3.4 million and 4.3 million employee stock options for the three and nine months ended September 27, 2024 and September 29, 2023, respectively, and 2.4 million restricted stock units for the three and nine months ended September 27, 2024 were excluded from the calculation of diluted earnings per share as they are antidilutive to the EPS calculation.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 11. Commitments and Contingencies In the Company’s joint venture arrangements, the liability of each partner is usually joint and several. This means as each joint venture partner may become liable for the entire risk of performance guarantees provided by each partner to the customer. Typically, each joint venture partner indemnifies the other partners for any liabilities incurred in excess of the liabilities the other party is obligated to bear under the respective joint venture agreement. In addition, the Company may be required to guarantee performance directly to the customer. The Company is unable to estimate the maximum potential amount of future payments that the Company could be required to make under outstanding performance guarantees related to joint venture projects due to a number of factors, including but not limited to, the nature and extent of any contractual defaults by the other joint venture partners, resource availability, potential performance delays caused by the defaults, the location of the projects, and the terms of the related contracts. In the ordinary course of business, the Company is subject to other claims, lawsuits, investigations and disputes arising out of the conduct of its business, including matters relating to commercial transactions, government contracts, and employment matters. The Company recognizes a liability for contingencies that are probable of occurrence and reasonably estimable. To date, no such matters are material to the condensed consolidated statements of operations. In certain contracts, there are provisions that require the Company to pay liquidated damages if the Company is responsible for the failure to meet specified contractual milestone dates and the applicable customer asserts a conforming claim under these provisions. These contracts define the conditions under which customers may make claims against the Company for liquidated damages. Based upon the evaluation of performance and other commercial and legal analysis, management has recognized relevant probable liquidated damages as of September 27, 2024 and December 29, 2023, and believes that the ultimate resolution of such matters will not materially affect the Company's condensed consolidated financial position, results of operations, or cash flows. The Company has recorded contingent consideration as of September 27, 2024 and December 29, 2023 at its estimated fair value. The Company is unable to reasonably determine an estimated range of amounts of the payments that could be made due to the uncertainty of future events. Guarantees The Company obtains bonding on construction contracts through third-party bonding companies. As is customary in the construction industry, the Company indemnifies the third-party bonding companies for any losses incurred by it in connection with bonds that are issued. The Company has granted the third-party bonding companies a security interest in accounts receivable, contract assets and contract rights for that obligation. The Company typically indemnifies contract owners for claims arising during the construction process and carries insurance coverage for such claims. Letters of Credit In the ordinary course of business and under certain contracts, the Company is required to post standby letters of credit for its insurance carriers. The Company did not have any letters of credit outstanding as of September 27, 2024 or December 29, 2023.

Subsequent Events [Abstract]
Subsequent Events	Note 12. Subsequent Events Legacy Project Settlement On October 31, 2024, the Company entered into a settlement agreement in its Golden Gate Bridge Project (the “GGB Project”). Under the terms of the settlement and through its consolidated joint venture with Danny’s Construction Co. LLC, Shimmick/Danny’s Joint Venture (“SDJV”), SDJV will receive total settlement proceeds of $ 97 million, a contract change order for reduced scope of work of $ 6 million and a contract change order for extension of project completion and costs incurred on the GGB Project. The GGB Project owner is required to pay SDJV $ 25 million within 14 business days of the executed agreement and the remaining $ 72 million cash payment to SDJV on or before December 17, 2024. After paying subcontractor pass-through claims, Shimmick plans to use the remaining proceeds for ongoing operations, including completion of the GGB Project. The settlement amount and reduction of outstanding scope of work are recorded in Contract assets, current and Contract liabilities, current within the condensed consolidated balance sheets. As a result of the GGB Project settlement and after accounting for subcontractor, legal and other costs as well as previously recorded revenue, the Company recognized an increase in gross margin of $ 11 million on the project during the three months ended September 27, 2024 within the condensed consolidated statements of operations.

The information furnished reflects all adjustments, consisting of normal recurring adjustments, that are, in the opinion of management, necessary for a fair presentation of the results of operations, cash flows and financial position for the interim periods presented. A statement of comprehensive income is not presented as the Company’s results of operations do not contain any items classified as comprehensive income. All intercompany accounts and transactions have been eliminated.
