Other than statements of historical fact, all information contained in this presentation, including, but not limited to, stateme nts regarding expected future financial performance (including the assumptions related thereto), including our revenue, net income and expected EBITDA; our growth prospects; our expectations regarding profitability; our continued successful adjustment to becoming a public company following our initial public offering; our expectations regarding successful partnerships with our new investors; and our capital plans and expectations related thereto, are forward-looking statements.

The Company has based these forward-looking statements largely on its current expectations and projections about future events and trends that it believes may affect its financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including but limited to, the following: our ability to accurately estimate risks, requirements or costs when we bid on or negotiate a contract; the impact of our fixed-price contracts; qualifying as an eligible bidder for contracts; the availability of qualified personnel, joint venture partners and subcontractors; inability to attract and retain qualified managers and skilled employees and the impact of loss of key management; higher costs to lease, acquire and maintain equipment necessary for our operations or a decline in the market value of owned equipment; subcontractors failing to satisfy their obligations to us or other parties or any inability to maintain subcontractor relationships; marketplace competition; our inability to obtain bonding; our limited operating history as an independent company following our separation from AECOM; our relationship and transactions with our prior owner, AECOM; AECOM defaulting on its contractual obligations to us or under agreements in which we are beneficiary; our limited number of customers; dependence on subcontractors and suppliers of materials; any inability to secure sufficient aggregates; an inability to complete a merger or acquisition or to integrate an acquired company’s business; adjustments in our contract backlog; accounting for our revenue and costs involves significant estimates, as does our use of the input method of revenue recognition based on costs incurred relative to total expected costs; material impairments; any failure to comply with covenants under any current indebtedness, and future indebtedness we may incur; the adequacy of sources of liquidity; cybersecurity attacks against, disruptions, failures or security breaches of, our information technology systems; seasonality of our business; pandemics and public health emergencies; commodity products price fluctuations and/or elevated interest rates; liabilities under environmental laws, compliance with immigration laws, and other regulatory matters, including changes in regulations and laws; climate change; deterioration of the U.S. economy; changes in state and federal laws, regulations or policies under the current Presidential administration, including changes in trade policies and regulations, including increases or changes in duties, current and potentially new tariffs or quotas and other similar measures, as well as the potential impact of retaliatory tariffs and other actions, and potential changes to the amounts provided for under the Infrastructure Investment and Jobs Act, as well as other legislation and executive orders related to governmental spending, and geopolitical risks, including those related to the war between Russia and Ukraine and the conflict in the Gaza strip and Red Sea Region; and other risks detailed in our filings with the Securities and Exchange Commission, including the “Risk Factors” section in our Annual Report on Form 10-K for the fiscal year ended January 3, 2025 and those described from time to time in our future reports with the SEC. Moreover, the Company operates in a very competitive and rapidly changing environment, and new risks emerge from time to time. It is not possible for the Company to predict all risks, nor can it assess the effect of all factors on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements it may make. In light of these risks, uncertainties, and assumptions, the future events and trends discussed in this presentation may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

2025 FULL YEAR GUIDANCE 7 In consideration of several factors, the Company has established full-year guidance for the fiscal year ending January 2, 2026. The Company considered its recent business trends and financial results, current growth plans, strategic initiatives, national economic outlook and the potential impact on results in establishing its guidance. We do not provide a reconciliation for forward-looking non-GAAP guidance because we are unable to predict certain items contained in the U.S. GAAP measures without unreasonable efforts. These items may include legal fees and other costs for a Non-Core Loss Project, acquisition-related costs, litigation charges or settlements, and certain other unusual adjustments. Non-Core Projects Gross MarginNon-Core Projects Revenue Shimmick Projects Gross MarginShimmick Projects Revenue $356M $405M - $415M 2024 2025 2024 2025 2024 2025 2024 2025 (53)% (5)% - (15)% $93M $80M - $90M 3% 9% - 12% For fiscal year ending January 2, 2026, we reaffirm our guidance and expect: Shimmick Projects revenue in the range of $405 million and $415 million, with gross margin between 9% and 12% Non-Core Projects revenue in the range of $80 million and $90 million, with gross margin between (15%) and (5%) Consolidated Adjusted EBITDA between $5 million and $15 million

CLOSING 8 Our investments in strategic backlog growth are yielding results and will continue into Q4 and into 2026 with increased backlog and revenue, driven by growing contributions from our electrical business Margins on core work is showing consistency and stability. As the remaining revenue represented by Non-Core Projects declines, we expect our overall margins to continue improving Operational improvements we put in place will allow us to optimize G&A costs, while driving top line growth and achieve consistent results

GAPP TO NON-GAAP RECONCILIATIONS 10 (1) Consists of transformation-related costs we have incurred including advisory costs in connection with settling outstanding claims in connection with exiting certain Non-Core Projects as part of the Company’s growth strategy to address and capitalize on the nation’s growing need for water and other critical infrastructure. (2) Reflects a strategic decision to enhance the Company’s current ERP system rather than implementing a new platform which, due to prior capitalized costs and remaining contractual obligations, resulted in a one-time charge of $16 million in the third quarter of fiscal 2024. (3) Consists of legal fees and other costs incurred in connection with claims relating to Non-Core Projects. (4) Consists of transaction-related costs and changes in fair value of contingent consideration remaining after the impact of transactions with our prior owner. *Please refer to the following page for explanatory notes regarding non-GAAP financial measures

NON-GAAP FINANCIAL MEASURESEXPLANATORY NOTES Adjusted Net (Loss) Income Adjusted net (loss) income represents Net loss attributable to Shimmick Corporation adjusted to eliminate stock- based compensation, ERP pre-implementation asset impairment and associated costs, legal fees and other costs for Non-Core Projects and other costs. We have also made an adjustment for transformation costs we have incurred including advisory costs in connection with settling outstanding claims, exiting the Non-Core Projects and transforming the Company to shift our strategy to meet the nation’s growing need for water and other critical infrastructure and grow our business. We have included Adjusted net (loss) income in this press release because it is a key measure used by our management and board of directors to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short and long-term operational plans. In particular, we believe that the exclusion of the income and expenses eliminated in calculating Adjusted net (loss) income can provide a useful measure for period-to-period comparisons of our core business. Accordingly, we believe that Adjusted net (loss) income provides useful information to investors and others in understanding and evaluating our results of operations. Our use of Adjusted net (loss) income as an analytical tool has limitations, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. Some of these limitations are: • Adjusted net (loss) income does not reflect changes in, or cash requirements for, our working capital needs, • Adjusted net (loss) income does not reflect the potentially dilutive impact of stock-based compensation, and • other companies, including companies in our industry, might calculate Adjusted net (loss) income or similarly titled measures differently, which reduces their usefulness as comparative measures. Because of these and other limitations, you should consider Adjusted net (loss) income alongside Net loss attributable to Shimmick Corporation, which is the most directly comparable GAAP measure. Adjusted EBITDA Adjusted EBITDA represents our Net loss attributable to Shimmick Corporation before interest expense, income tax benefit and depreciation and amortization, adjusted to eliminate stock-based compensation, ERP pre- implementation asset impairment and associated costs, legal fees and other costs for Non-Core Projects and other costs. We have also made an adjustment for transformation costs we have incurred including advisory costs in connection with settling outstanding claims, exiting the Non-Core Projects and transforming the Company to shift our strategy to meet the nation’s growing need for water and other critical infrastructure and grow our business. We have included Adjusted EBITDA because it is a key measure used by our management and Board to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short and long-term operational plans. In particular, we believe that the exclusion of the income and expenses eliminated in calculating Adjusted EBITDA can provide a useful measure for period-to-period comparisons of our core business. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our results of operations. Our use of Adjusted EBITDA as an analytical tool has limitations, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. Some of these limitations are: • although depreciation and amortization are non-cash charges, the assets being depreciated and amortized might have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements, • Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs, • Adjusted EBITDA does not reflect the potentially dilutive impact of stock-based compensation, • Adjusted EBITDA does not reflect interest or tax payments that would reduce the cash available to us, and • other companies, including companies in our industry, might calculate Adjusted EBITDA or similarly titled measures differently, which reduces their usefulness as comparative measures. Because of these and other limitations, you should consider Adjusted EBITDA alongside Net loss attributable to Shimmick Corporation, which is the most directly comparable GAAP measure. Guidance provided is only an estimate of what we believe is reasonable as of the date of this presentation. We are not readily able to provide a reconciliation of non-GAAP measures to the most comparable GAAP metrics without unreasonable effort. Actual results will vary from the guidance, and the variations may be material. We undertake no intent or obligation to publicly update or revise any of these projections, whether as a result of new information, future events or otherwise, except as required by law.
