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.

Note 3. Revenue, Receivables and Contract Assets and Liabilities

Remaining performance obligations

The Company had $860million of remaining performance obligations yet to be satisfied as of June 28, 2024. Our remaining performance obligations have a weighted average life of 2.3 years as of June 28, 2024.

Contract Balances

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 $24 million during the six months ended June 28, 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.

Substantially all contract assets as of June 28, 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. See Note 12 - Subsequent Events for the settlement of a claim on a large Legacy Project.

Revisions in Estimates

Changes in contract estimates resulted in net decreases in gross margin of $33million for the three months ended June 28, 2024, primarily due to the settlement further described in Note 12 - Subsequent Events and increased forecasted cost to complete loss jobs. Changes in contract estimates resulted in net decreases in gross margin of $51million for the six months ended June 28, 2024, primarily due to the settlement and increased forecasted cost to complete loss jobs.

Changes in contract estimates resulted in net decreases in gross margin of $15million for the three and six months ended June 30, 2023, primarily due to increased forecasted costs to complete and an agreed upon contract settlement lower than previously estimated.

Note 4. Joint Ventures and Variable Interest Entities

The assets of the Company's consolidated joint ventures are restricted for use only by the particular joint venture and are not available for the general operations of the Company.

As of June 28, 2024 and December 29, 2023, the Company's investment in unconsolidated joint ventures was $22million and $21million, respectively.

The Company recognized equity in loss of unconsolidated joint ventures of $2million for each of the three and six months ended June 28, 2024 and equity in earnings of unconsolidated joint ventures of $8million and $7million for the three and six months ended June 30, 2023, respectively.

Contractually required support provided to the Company's joint ventures is discussed in Note 11 - Commitments and Contingencies.

Related Party Transactions

We often provide construction management and other subcontractor services to the Company's joint ventures and revenue includes amounts related to these services which is eliminated to the extent of our ownership. Revenue included related to services provided to unconsolidated joint venture related parties is as follows:

Note 5. Property, Plant and Equipment and Intangible Assets

Depreciation is recorded within cost of revenue and selling, general and administrative expenses and is calculated using the straight-line method over the estimated useful lives of the assets, or in the case of leasehold improvements and capitalized leases, the lesser of the remaining term of the lease or its estimated useful life.

Note 6. Debt

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 $30million. The Revolving Credit Facility was subsequently amended on June 30, 2023, September 22, 2023, May 20, 2024 and August 14, 2024. As amended, the Revolving Credit Facility provides for a total commitment of $2.8million 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 $7.5million. As of June 28, 2024, we were not in compliance with the Permitted Investments covenant regarding investments in joint ventures set forth in the Revolving Credit Facility. As a result of the August 14, 2024 amendment, which redefined Permitted Investments, we are not aware of any instances of noncompliance with financial covenants. The Revolving Credit Facility matures on August 31, 2024. In the three months ended June 28, 2024, we repaid $17million of the amount outstanding under the Revolving Credit Facility. As of June 28, 2024 and December 29, 2023, $15million and $30million was outstanding under the Revolving Credit Facility, respectively.

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"). The Credit Agreement provides borrowing capacity up to $60million. 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 third 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 June 28, 2024. As of June 28, 2024, $54million was outstanding under the Credit Facility.

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 six months ended June 28, 2024 and June 30, 2023.

For the six months ended June 28, 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 six months ended June 30, 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 zeroeffective 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 $147million and $124million as of June 28, 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.

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 5,477,200of 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 yearsand vest over four yearsof service.

On November 13, 2023, the Company's Board approved the Shimmick Corporation 2023 Equity Incentive Plan (the "2023 Omnibus Incentive Plan"). 3,729,149is 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 $2million and $1million for the six months ended June 28, 2024 and June 30, 2023, respectively. Unrecognized compensation expense related to stock-basedgrants to employees of Shimmick outstanding as of June 28, 2024 and June 30, 2023 was $5million and $4million, respectively, to be recognized on a straight-line basis over the awards' weighted average remaining vesting period of 0.8 years and 1.8years, respectively.

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 3.5million and 4.5million employee stock options were excluded from the calculation of diluted earnings per share for the three and six months ended June 28, 2024 and June 30, 2023, respectively, as they are antidilutive to the EPS calculation.
