Reported gross margin of $5 million, as compared to gross margin of $(16) million during the first quarter of 2024

•

Reported selling, general and administrative expenses of $14 million, down 11% from the first quarter of 2024 as a result of the continued implementation of the transformation plan

•

“Our business model continues to prove resilient amid broader macroeconomic factors such as tariffs and supply chain pressures, reflecting both the strength of our disciplined approach and execution of our long-term strategy. We have a robust backlog, supported by a strong 12-month bidding outlook that reflects the quality of our pipeline and the competitiveness of our offerings. Notably, we are seeing heightened demand and opportunities in electrical, water and environmental infrastructure sectors – areas where we bring deep technical expertise and a strong track record of performance.

(1) Shimmick Projects are those projects started after prior ownership that have focused on water, climate resilience, energy transition, and sustainable transportation.

(2) Legacy Projects are those projects started under prior ownership. Projects that focus on foundation drilling are referred to as "Foundations Projects". The Company entered into an agreement to sell the assets of non-core foundation projects in the second quarter of 2024 and continued to wind down remaining work during the remainder of the 2024 fiscal year and three months ended April 4, 2025. As a result, revenue from Foundations Projects will continue to decline during the remainder of the 2025 fiscal year.

Shimmick Projects

Projects started after the AECOM Sale Transaction ("Shimmick Projects") have focused on critical infrastructure aligned with our strategy, including water, climate resilience, energy transition and sustainable transportation. Revenue recognized on Shimmick Projects was $93 million and $90 million for the three months ended April 4, 2025 and March 29, 2024, respectively. The $3 million increase in revenue was primarily the result of $13 million of revenue from a California Palisades fire clean-up project and $10 million of revenue from new water and infrastructure projects ramping up, partially offset by a $20 million decrease from lower activity on existing projects and projects winding down.

Gross margin recognized on Shimmick Projects was $5 million and $(1) million for the three months ended April 4, 2025 and March 29, 2024, respectively. The $6 million increase in the gross margin was primarily the result of $3 million in gross margin from a California Palisades fire clean-up project and $3 million in gross margin from new water and infrastructure projects ramping up.

Legacy and Foundations Projects

As part of the AECOM Sale Transaction, we acquired the Legacy Projects and backlog that were started under prior ownership. The Company entered into an agreement to sell the assets of our non-core Foundations Projects in the second quarter of 2024 and continued to wind down the remaining work which is largely completed.

Legacy and Foundations Projects revenue was $29 million and $30 million for the three months ended April 4, 2025 and March 29, 2024, respectively. The $1 million decrease was due to the Company working to wind down these projects.

Gross margin was $(1) million for the three months ended April 4, 2025 as compared to $(15) million for the three months ended March 29, 2024. The $14 million increase was primarily the result of cost increases for time and design-related schedule extensions identified during the first quarter of 2024 which did not reoccur during the three months ended April 4, 2025.

A subset of Legacy Projects ("Legacy Loss Projects") have experienced significant cost overruns due to the COVID pandemic, design issues, legal costs and other factors. In the Legacy Loss Projects, we have recognized the estimated costs to complete and the loss expected from these projects. If the estimates of costs to complete fixed-price contracts indicate a further loss, the entire amount of the additional loss expected over the life of the project is recognized as a period cost in the cost of revenue. As these Legacy Loss Projects continue to wind down to completion, no further gross margin will be recognized and in some cases, there may be additional costs associated with these projects. Revenue recognized on these Legacy Loss Projects was $18 million and $15 million for the three months ended April 4, 2025 and March 29, 2024, respectively. Gross margin recognized on these Legacy Loss Projects was $(2) million and $(11) million for the three months ended April 4, 2025 and March 29, 2024, respectively. The change in gross margin was primarily the result of cost increases for time and design-related schedule extensions identified during the first quarter of 2024 which did not reoccur during the three months ended April 4, 2025.

Selling, general and administrative expenses

Selling, general and administrative expenses decreased by $2 million primarily as a result of reduced salary, bonus and legal expenses incurred during the three months ended April 4, 2025 as compared to the three months ended March 29, 2024.

Equity in earnings of unconsolidated joint ventures

Equity in earnings of unconsolidated joint ventures remained approximately flat period over period.

Gain (loss) on sale of assets

Gain (loss) on sale of assets remained approximately flat period over period.

Interest expense and Other (income) expense, net

Interest expense and other (income) expense, net remained approximately flat period over period.

Income tax expense

Due to an expected tax loss for the fiscal year ending 2025 and fiscal year ended 2024, no income tax expense was recorded in either period.

Net loss

Net loss decreased by $24 million to a net loss of $10 million for the three months ended April 4, 2025, primarily due to increase in gross margin of $21 million and decrease in salary, general and administrative expenses of $2 million as described above.

Diluted loss per common share was $(0.28) for the three months ended April 4, 2025, compared to diluted loss per common share of $(1.30) for the same period in 2024.

Adjusted net loss was $(7) million for the three months ended April 4, 2025, compared to an adjusted net loss of $(29) million for the same period in 2024.

Adjusted diluted loss per common share was $(0.22) for the three months ended April 4, 2025, compared to $(1.15) for the same period in 2024.

Adjusted EBITDA was $(3) million for the three months ended April 4, 2025, compared to $(24) million for the same period in 2024.

Fiscal Year 2025 Guidance

For the full 2025 fiscal year, we expect:

•

Shimmick Projects revenue to increase 10% to 15%, with overall gross margin between 9% and 12%

•

Legacy Projects and Foundations Projects revenue between $50 million and $60 million with gross margin between (5)% and (15)% as we complete these projects

•

Adjusted EBITDA between $15 million and $25 million.

“We are pleased with our first quarter results and the momentum it provides to start 2025. We grew our top-line, slightly, while achieving significant improvement in our gross margin for the quarter, year-over-year. The results are a testament to the work the team is doing to advance our strategy, which is centered around building a Sustainable Backlog, with a renewed focus on Operational Excellence and People and Culture. While we continue to closely monitor the fluidity of tariff policy, at this point we are reaffirming our full year guidance, and we expect to deliver results in our previously stated guidance ranges” said Todd Yoder, Executive Vice President and Chief Financial Officer.

EXPLANATORY NOTES

Non-GAAP Financial Measures

Adjusted Net Loss and Adjusted Diluted Earnings Per Common Share

Adjusted net loss represents Net loss attributable to Shimmick Corporation adjusted to eliminate stock-based compensation, legal fees and other costs for Legacy 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 Legacy 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 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 can provide a useful measure for period-to-period comparisons of our core business. Accordingly, we believe that Adjusted net loss provides useful information to investors and others in understanding and evaluating our results of operations.

Our use of Adjusted net loss 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 does not reflect changes in, or cash requirements for, our working capital needs,

•

Adjusted net loss does not reflect the potentially dilutive impact of stock-based compensation, and

•

other companies, including companies in our industry, might calculate Adjusted net loss or similarly titled measures differently, which reduces their usefulness as comparative measures.

Because of these and other limitations, you should consider Adjusted net loss alongside Net loss attributable to Shimmick Corporation, which is the most directly comparable GAAP measure.

(2) Consists of legal fees and other costs incurred in connection with claims relating to Legacy Projects.

(3) Consists of transaction-related costs and changes in fair value of contingent consideration remaining after the impact of transactions with our prior owner.

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, legal fees and other costs for Legacy 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 Legacy 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 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 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.
