PRELIMINARY PROSPECTUS

    Shares

Common Stock

This is Shimmick Corporation’s initial public offering, and prior to this offering, there has been no public market for our common stock. We are offering      shares of our common stock and anticipate that the initial public offering price will be between $   and $   per share. We intend to apply for listing of our common stock on The Nasdaq Stock Market LLC (“Nasdaq”) under the symbol “SHIM.”

We are an “emerging growth company” and a “smaller reporting company” under the federal securities laws and will be subject to reduced public company reporting requirements. See “Prospectus Summary — Implications of Being an Emerging Growth Company and a Smaller Reporting Company.”

After the completion of this offering, our controlling stockholder (see “Principal Stockholders”) will continue to control a majority of the voting power of our common stock. As a result, although we do not expect to rely on the “controlled company” exemption, we will be a “controlled company” under the listing standards of Nasdaq and the rules of the Securities and Exchange Commission (“SEC”), and we will qualify for exemptions from certain corporate governance requirements. See “Management — Controlled Company Exemption.”

Investing in our common stock involves a high degree of risk. Please read “Risk Factors” beginning on page 19 of this prospectus for a discussion of some of the risks you should consider before investing.

We have granted the underwriters an option, exercisable within 30 days of the date of this prospectus, to purchase a maximum of    additional shares of our common stock from us at the initial public offering price, less the underwriting discounts and commissions, to cover over-allotments of shares, if any.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The underwriters expect to deliver the shares of our common stock to purchasers against payment on or about     , 2023.

NON-GAAP FINANCIAL MEASURES

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We also supplement our consolidated financial statements with non-GAAP financial measures in this prospectus, including Adjusted net income (loss) and Adjusted EBITDA. For a discussion of the limitations on these measures and the rationales for using these measures see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Non-GAAP Financial Measures.”

FISCAL YEAR

We operate on a 52-week or 53-week fiscal year ending on the Friday closest to December 31 each year. Our fiscal year is divided into four quarters of 13 weeks, each beginning on a Saturday and containing one 5-week period along with two 4-week periods. When a 53-week fiscal year occurs, we report the additional week in the fourth fiscal quarter. References to fiscal year 2022 are to our 52-week fiscal year ended December 30, 2022 and references to fiscal year 2021 are to our 52-week fiscal year ended December 31, 2021.

RISK FACTORS

An investment in our common stock involves risks. You should carefully consider each of the following risks and all of the information set forth in this prospectus before deciding to invest in our common stock. The risks and uncertainties described below are not the only ones we face. If any of the following risks and uncertainties develops into actual events, our business, financial condition, results of operations and cash flows could be materially adversely affected. In that case, the price of our common stock could decline and you may lose all or part of your investment.

Risks Related to Our Projects

If we are unable to accurately estimate the overall risks, requirements or costs when we bid on or negotiate a contract that is ultimately awarded to us, we may achieve a lower than anticipated profit or incur a loss on the contract.

The majority of our revenue and backlog are derived from fixed unit price contracts and lump sum contracts. The nature of our contracts, particularly those that are fixed-price, subjects us to risks associated with cost overruns, operating cost inflation and potential claims for liquidated damages. Fixed unit price contracts require us to provide materials and services at a fixed unit price based on approved quantities irrespective of our actual per unit costs. Lump sum contracts require that the total amount of work be performed for a single price irrespective of our actual per unit costs. We realize a profit on our contracts only if we accurately estimate our costs and then successfully control actual costs and avoid cost overruns, and our revenue exceed actual costs. If our cost estimates for a contract are inaccurate, or if we do not execute the contract within our cost estimates, then cost overruns may cause us to incur losses or cause the contract not to be as profitable as we expected. The final results under these types of contracts could negatively affect our business, financial condition, results of operations and cash flows.

The costs incurred and gross margin realized on our contracts can vary, sometimes substantially, from our original projections due to a variety of factors, including, but not limited to:

19

Many of our contracts with public customers contain provisions that purport to shift some or all of the above risks from the customer to us, even in cases where the customer is partly at fault. Our experience has often been that public customers have been willing to negotiate equitable adjustments in the contract compensation or completion time provisions if unexpected circumstances arise. However, public customers may seek to impose contractual risk-shifting provisions more aggressively or there could be statutory and other legal prohibitions that prevent or limit contract changes or equitable adjustments, which could increase risks and adversely affect our business, financial condition, results of operations and cash flows.

We have a limited operating history as an independent company and have been historically dependent on our prior owner, AECOM.

We operated as a division of AECOM until our separation in January 2021. Accordingly, our business historically relied upon AECOM’s corporate infrastructure for services to support our business functions and relationships with third-party providers. Since separating from AECOM, we have worked to create and/or supplement the corporate infrastructure necessary to operate as an independent company, and have incurred related costs and expenses. That said, we have expended, and expect to continue to expend, significant efforts and costs to (i) replace or otherwise upgrade our systems, including our information technology (IT) and enterprise resource planning systems, (ii) implement additional financial, IT, and management controls, (iii) implement reporting systems and procedures, (iv) hire additional management, IT, accounting, finance, legal, human resources, and other administrative staff and third-party service providers, (v) establish employee benefit programs, (vi) create a board of directors and corporate governance programs, (vii) carry out audit, tax and legal functions, and (viii) establish banking and credit facility arrangements. Any interruption in these services could have a material adverse effect on our business, financial condition, results of operations, profitability, cash flows and growth products. We may also be unable to obtain necessary bonding as we historically were dependent on AECOM to provide the requisite credit support. See “Risks Related to our Business and Industry — An inability to obtain bonding could limit the aggregate dollar amount of contracts that we are able to pursue.”

Our customers may be adversely affected by market conditions and economic downturns, which could impair their ability to pay for our services.

Economic downturns could reduce capital expenditures in the industries we serve, which could result in decreased demand for our services. The demand for our services has been, and will likely continue to be, cyclical in nature and vulnerable to general downturns in the U.S. economy. During economic downturns, our customers may not have the ability to fund capital expenditures for infrastructure, or may have difficulty obtaining financing for planned projects. In addition, uncertain or adverse economic conditions that create volatility in the credit and equity markets may reduce the availability of debt or equity financing for our customers, causing them to reduce capital spending. This has resulted, and in the future could result, in cancellations of projects or deferral of projects to a later date. Such cancellations or deferrals could materially and adversely affect our results of operations, cash flows and liquidity. These conditions could also make it difficult to estimate our customers’ demand for our services and add uncertainty to the determination of our backlog. In addition, our customers are negatively affected by economic downturns that decrease the need for their services or the profitability of their services. During an economic downturn, our customers also may not have the ability or desire to continue to fund capital expenditures for infrastructure or may outsource less work. A decrease in related project work could negatively impact demand for the services we provide and could materially adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

20

Many of our customers are regulated by federal, state and local government agencies, and the addition of new regulations or changes to existing regulations may adversely impact the demand and profitability of our services.

Many of our customers are regulated by federal, state and local government agencies. These agencies could change the way in which they interpret the application of current regulations and/or may impose additional regulations. Interpretative changes or new regulations having an adverse effect on our customers and the profitability of the services they provide could reduce demand for our services, which could adversely affect our results of operations, cash flows and liquidity. Any future restrictions or regulations that might be adopted could lead to operational delays, increased operating costs for our customers, reduced capital spending and/or delays or cancellations of future infrastructure projects, which could materially and adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Our business depends on our ability to qualify as an eligible bidder under federal, state or local government contract criteria and to compete successfully against other qualified bidders in order to obtain federal, state or local government contracts.

Federal, state and local government agencies conduct rigorous competitive processes for awarding many contracts. Some contracts include multiple award task order contracts in which several contractors are selected as eligible bidders for future work. We will potentially face strong competition and pricing pressures for any additional contract awards from other government agencies, and we may be required to qualify or continue to qualify under various multiple award task order contract criteria. Our inability to qualify as an eligible bidder under federal, state or local government contract criteria could preclude us from competing for certain other government contract awards. In addition, our inability to qualify as an eligible bidder, or to compete successfully when bidding for certain federal, state or local government contracts and to win those contracts, could materially adversely affect our business, operations, revenue and profits.

Government contracts generally are subject to a variety of governmental regulations, requirements and statutes, the violation or alleged violation of which could have a material adverse effect on our business.

A majority of our total revenue is derived from contracts funded by federal, state and local government agencies and authorities. Government contracts are subject to specific procurement regulations, contract provisions and a variety of socioeconomic requirements relating to their formation, administration, performance and accounting and often include express or implied certifications of compliance. Further, government contracts include the right to modify, delay, curtail, renegotiate or terminate contracts and subcontracts at the government’s convenience any time prior to their completion. Claims for civil or criminal fraud may be brought for violations of regulations, requirements or statutes. We may also be subject to qui tam (whistle blower) litigation brought by private individuals on behalf of the government under the False Claims Act, which could include claims for up to treble damages. Further, if we fail to comply with any of the regulations, requirements or statutes or if we have a substantial number of accumulated OSHA, Mine Safety and Health Administration or other workplace safety violations, our existing government contracts could be terminated and we could be suspended from government contracting or subcontracting, including federally funded projects at the state level. Should one or more of these events occur, it could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Government contractors are subject to suspension or debarment from government contracting.

Our substantial dependence on government contracts exposes us to a variety of risks that differ from those associated with contracts with private owners. Various statutes to which our operations are subject, including the Davis-Bacon Act (which regulates wages and benefits), the Walsh-Healy Act (which prescribes a minimum wage and regulates overtime and working conditions), Executive Order 11246 (which establishes equal employment opportunity and affirmative action requirements) and the Drug-Free Workplace Act, provide for mandatory suspension and/or debarment of contractors in certain circumstances involving statutory violations. In addition, our

21

federal government and certain state and local agency contracts are subject to, among other regulations, regulations issued under the Federal Acquisition Regulations (“FAR”). These regulations can limit the recovery of certain specified indirect costs on contracts and subject us to ongoing multiple audits by government agencies such as the Defense Contract Audit Agency (“DCAA”). Audits by the DCAA and other agencies consist of reviews of our overhead rates, operating systems and cost proposals to ensure that we have accounted for such costs in accordance with the Cost Accounting Standards of the FAR (“CAS”). If the DCAA determines that we have not accounted for such costs consistent with CAS, the DCAA may disallow these costs. There can be no assurance that audits by the DCAA or other governmental agencies will not result in material cost disallowances in the future, which could adversely impact our business, financial condition, results of operations and cash flows.

Further, FAR and various state statutes provide for discretionary suspension and/or debarment in certain circumstances that might call into question a contractor’s willingness or ability to act responsibly, including as a result of being convicted of, or being found civilly liable for, fraud or a criminal offense in connection with obtaining, attempting to obtain or performing a public contract or subcontract. The scope and duration of any suspension or debarment may vary depending upon the facts and the statutory or regulatory grounds for debarment and could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our success depends on attracting and retaining qualified personnel, joint venture partners, advisors and subcontractors in a competitive environment.

The success of our business is dependent on our ability to attract, develop and retain qualified personnel, joint venture partners, advisors and subcontractors. Changes in general or local economic conditions and the resulting impact on the labor market and on our joint venture partners may make it difficult to attract or retain qualified individuals in the geographic areas where we perform our work. If we are unable to provide competitive compensation packages, high-quality training programs and attractive work environments or to establish and maintain successful partnerships, our ability to profitably execute our work could be adversely impacted.

We rely heavily on immigrant labor. We have taken steps that we believe are sufficient and appropriate to ensure compliance with immigration laws. However, we cannot provide assurance that we have identified, or will identify in the future, all illegal immigrants who work for us. Our failure to identify illegal immigrants who work for us may result in fines or other penalties being imposed upon us, which could have a material adverse effect on our operations, results of operations and financial condition.

Our failure to meet the schedule or performance requirements of our contracts could adversely affect us.

In most cases, our contracts require completion by a scheduled acceptance date. Failure to meet any such schedule could result in additional costs, penalties or liquidated damages being assessed against us, and these could exceed projected profit margins on the contract. Performance problems on existing and future contracts could cause actual results of operations to differ materially from those anticipated by us and could cause us to suffer damage to our reputation within the industry and among our customers.

Adverse weather conditions may cause delays, which could slow completion of our contracts and negatively affect our revenue and cash flows.

Because all of our construction projects are built outdoors, work on our contracts is subject to unpredictable weather conditions. While weather has historically had a minimal impact on our operation due to the concentration of our work in California, where the climate is generally temperate, weather could have an increasingly frequent or severe effect on our operations if general climatic changes occur or if we expand into other geographic regions that tend to experience more extreme weather conditions. Lengthy periods of wet or cold winter weather could interrupt construction, and this could lead to under-utilization of crews and equipment, resulting in less efficient rates of overhead recovery. Extreme heat could prevent us from performing certain types of operations. Changes in weather conditions could cause delays and otherwise significantly affect our

22

project costs. While revenue might be recovered following a period of bad weather, it would generally be impossible to recover the cost of inefficiencies, and significant periods of bad weather typically would reduce profitability of affected contracts both in the current period and during the future life of affected contracts. Such reductions in contract profitability would negatively affect our results of operations.

We may be unable to identify and contract with qualified Disadvantaged Business Enterprise (“DBE”) contractors to perform as subcontractors.

Certain of our government agency projects contain minimum DBE participation clauses. If we subsequently fail to complete these projects with the minimum DBE participation, we may be held responsible for breach of contract, which may include restrictions on our ability to bid on future projects as well as monetary damages. To the extent we are responsible for monetary damages, the total costs of the project could exceed our original estimates, we could experience reduced profits or a loss for that project and there could be a material adverse impact to our business, financial condition, results of operations and cash flows.

Design-build contracts subject us to the risk of design errors and omissions.

Design-build is increasingly being used as a method of project delivery as it provides the customer with a single point of responsibility for both design and construction. We normally subcontract design responsibility to architectural and engineering firms. In the event of a design error or omission by a subcontractor or by us causing damages, there is risk that we, the subcontractor or the respective professional liability insurance or errors and omissions insurance would not be able to absorb the liability. Any liabilities resulting from an asserted design defect with respect to our construction projects may have a material adverse effect on our financial condition, results of operations and cash flows.

If we are unable to attract and retain qualified managers and skilled employees or if we were to lose the benefit of the experience, efforts and abilities of one or more certain key personnel, we will be unable to operate efficiently, which could reduce our revenue, profitability and liquidity.

Our business is labor intensive, and some of our operations experience a high rate of employee turnover. In addition, given the nature of the highly specialized work we perform, many of our employees are trained in, and possess, specialized technical skills that are necessary to operate our business and maintain productivity and profitability. At times of low unemployment rates in the areas we serve, it can be difficult for us to find qualified and affordable personnel. We may be unable to hire and retain a sufficiently skilled labor force necessary to support our operating requirements and growth strategy. Our labor and training expenses may increase as a result of a shortage in the supply of skilled personnel. We may not be able to pass these expenses on to our customers, which could adversely affect our profitability. Labor shortages, increased labor or training costs, or the loss of key personnel could materially adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Additionally, our business is managed by a number of key executive and operational officers and is dependent upon retaining and recruiting qualified management. Our continuing success depends on the performance of our management team. We cannot guarantee the continued employment of any of our key executives and operational officers who may choose to leave our company for any number of reasons, such as other business opportunities, differing views on our strategic direction or other reasons. We rely on the experience, efforts and abilities of these individuals, each of whom would be difficult to replace. We intend to enter into employment agreements with our key executives prior to the completion of this offering, however, the employment agreements will not guarantee their continued service to us.

23

Our failure to adequately collect for extra or change order work or recover on claims brought by us against customers or other project participants for additional contract costs could have a negative impact on our liquidity and future operations.

In certain circumstances, we seek to collect or assert claims against customers, engineers, consultants, subcontractors or others involved in a project for additional costs exceeding the contract price or for amounts not included in the original contract price. These situations may occur due to changes in the initial project scope. Our contracts often require us to perform extra or change order work as directed by the customer even if the customer has not agreed in advance on the scope or price of the extra work to be performed. This process may result in disputes over whether the work performed is beyond the scope of the work included in the original project plans and specifications or, if the customer agrees that the work performed qualifies as extra work, the price that the customer is willing to pay for the extra work. These situations also may occur due to other matters, such as delays, which may result in additional costs. Our attempts to collect for additional costs generally are subject to protracted negotiations. Often, these claims can be the subject of lengthy arbitration or litigation proceedings, and it is difficult to accurately predict when and the terms upon which these claims will be fully resolved. These matters ultimately may not be settled to our satisfaction. When these types of events occur, we use working capital in projects to promptly and fully cover cost overruns pending the resolution of the relevant claims. This period of time may be lengthy for project changes, even when the customer agrees to pay for the extra work, as a result of the customer’s approval process. A failure to recover in these types of situations promptly and fully could have a negative impact on our liquidity and results of operations. In addition, while customers and subcontractors may be obligated to indemnify us against certain liabilities, such third parties may refuse or be unable to pay us.

To the extent that actual recoveries with respect to change orders or amounts subject to contract disputes or claims are less than the estimates used in our financial statements, the amount of any shortfall will reduce our future revenue and profits, and this could have a material adverse effect on our reported working capital and results of operations. In addition, any delay caused by the extra work may adversely impact the timely scheduling of other project work and our ability to meet specified contract milestone dates.

Our operations are subject to hazards that may cause personal injury or property damage. Failure to maintain safe work sites could subject us to liabilities and possible losses, which may not be covered by insurance.

Construction and maintenance sites, plants and quarries are potentially dangerous workplaces subject to the usual hazards associated with providing construction and related services, and our employees and others are often put in close proximity with mechanized equipment, moving vehicles, chemical and manufacturing processes and highly regulated materials. Operating hazards can cause personal injury and loss of life, damage to or destruction of property, plant and equipment and environmental damage.

On many sites, we are responsible for safety and, accordingly, must implement safety procedures. If we fail to implement these procedures or if the procedures we implement are ineffective, we may suffer the loss of or injury to our employees or others, as well as expose ourselves to possible litigation. Despite having invested significant resources in safety programs and being recognized as an industry leader, a serious accident may nonetheless occur on one of our worksites. As a result, our failure to maintain adequate safety standards could result in reduced profitability or the loss of projects or customers and could have a material adverse impact on our business, financial condition, results of operations, and cash flows.

We maintain general liability and excess liability insurance, workers’ compensation insurance, auto insurance and other types of insurance all in amounts consistent with our risk of loss and industry practice, but this insurance may not be adequate to cover all losses or liabilities that we may incur in our operations. Insurance liabilities are difficult to assess and quantify due to unknown factors, including the severity of an injury, the determination of our liability in proportion to other parties, the number of incidents not reported and the effectiveness of our safety program. If we were to experience insurance claims or costs above our estimates, we might be required to use working capital to satisfy these claims rather than to maintain or expand our operations.

24

To the extent that we experience a material increase in the frequency or severity of accidents or workers’ compensation and health claims, or unfavorable developments on existing claims, our results of operations and financial condition could be materially and adversely affected.

We could incur material costs and losses as a result of claims that our materials do not meet regulatory requirements or contractual specifications.

We provide our customers with materials designed to comply with building codes or other regulatory requirements, as well as any applicable contractual specifications. If our materials do not satisfy these requirements and specifications, material claims may arise against us, our reputation could be damaged and, if any such claims are for an uninsured, non-indemnified or product-related matter, then resolution of such claim against us could have a material adverse effect on our financial condition, results of operations or liquidity.

We may incur higher costs to lease, acquire and maintain equipment necessary for our operations, and the market value of our owned equipment may decline.

A significant portion of our projects are built with our own construction equipment rather than leased or rented equipment. To the extent that we are unable to buy construction equipment necessary for our needs, either due to a lack of available funding or equipment shortages in the marketplace, we may be forced to rent equipment on a short-term basis, which could increase the costs of performing our contracts.

The equipment that we own or lease requires continuous maintenance, for which we maintain our own repair facilities. If we are unable to continue to maintain the equipment in our fleet, we may be forced to obtain third-party repair services, which could increase our costs. In addition, the market value of our equipment may unexpectedly decline at a faster rate than anticipated.

Force majeure events, such as natural disasters, epidemics, pandemics and terrorists’ actions, could negatively impact our business, which may affect our financial condition, results of operations or cash flows.

Force majeure or extraordinary events beyond the control of the contracting parties, such as natural and man-made disasters, epidemics, pandemics and terrorists’ actions, could negatively impact the economies in which we operate. We often negotiate contract language where we are allowed certain relief from force majeure events in private customer contracts and review and attempt to mitigate force majeure events in both public and private customer contracts. We remain obligated to perform our services after most extraordinary events subject to relief that may be available pursuant to a force majeure clause. If we are not able to react quickly to force majeure events, our operations may be affected significantly, which would have a negative impact on our business, financial condition, results of operations and cash flows.

We may choose, or be required, to pay our subcontractors even if our customers do not pay, or delay paying us for the related services.

We use subcontractors to perform portions of our services. In some cases, we pay our subcontractors before our customers pay us for the related services. We could experience a material decrease in profitability and liquidity if we choose, or are required, to pay our subcontractors for work performed for customers that fail to pay, or delay paying us, for the related work.

Our subcontractors may fail to satisfy their obligations to us or other parties, or we may be unable to maintain these relationships, either of which may have a material adverse effect on our business, financial condition, results of operations, profitability, cash flows and growth prospects.

We depend on subcontractors to perform work on some of our projects. There is a risk that we may have disputes with subcontractors arising from, among other things, the quality and timeliness of the work they perform,

25

customer concerns about our subcontractors, or our failure to extend existing work orders or issue new work orders under a subcontracting arrangement. If any of our subcontractors fails to deliver the agreed-upon supplies and/or perform the agreed-upon services on a timely basis, then our ability to fulfill our obligations as a prime contractor may be jeopardized. In addition, the absence of qualified subcontractors with whom we have satisfactory relationships could adversely affect our ability to perform under some of our contracts or the quality of the services we provide. Any of these factors could have a material adverse effect on our results of operations, cash flows and liquidity.

We also rely on suppliers to obtain the necessary materials for certain projects, and on equipment manufacturers and lessors to provide us with the equipment we require to conduct our operations. Although we are not dependent on any single supplier or equipment manufacturer or lessor, any substantial limitation on the availability of required suppliers or equipment could negatively affect our operations. Market and economic conditions could contribute to a lack of available suppliers or equipment. If we cannot acquire sufficient materials or equipment, it could materially and adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

Risks Related to Our Business and Industry

Our business has been affected by numerous economic factors, including inflation, volatile financial markets, supply chain disruptions and shortages of materials and labor.

Economic conditions, including inflation, supply chain disruptions and labor and materials shortages, have negatively impacted us, and may continue to do so in the future. Following the onset of the COVID-19 pandemic and with the ongoing conflict between Ukraine and Russia in Europe, there has been a high degree of volatility in commodity and energy markets that affects our customers’ businesses. In addition, inflationary factors, such as increases in the labor costs, material costs, and overhead costs, may also adversely affect our financial condition and results of operations. Inflation in the United States has reached multi-decade highs and has been increasing since 2021. In some cases, we have had to bid more competitively than before to win work, which has compressed margins given the higher inflation. Additionally, in March 2023, the FDIC took control and was appointed receiver of Silicon Valley Bank and New York Signature Bank. While we do not have any direct exposure to these banks, if other banks and financial institutions enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, our operations may be negatively impacted, including any inability on our part, or on our customers’ parts, to access cash, cash equivalents or investments. Inflation, increases in interest rates and energy costs, bank failures, and other economic factors may have the effect of further increasing economic uncertainty and heightening the risks caused by volatility in financial markets, which may result in economic downturn or recession.

Although the water infrastructure market is relatively less susceptible to fluctuations in the market, economic downturns or reductions in government funding of infrastructure projects could reduce our revenue and profits and have a material adverse effect on our results of operations.

Our business is highly dependent on the amount and timing of infrastructure work funded by various governmental entities, which, in turn, depends on the overall condition of the economy, the need for new or replacement infrastructure, the priorities placed on various projects funded by governmental entities and federal, state or local government spending levels. Spending on infrastructure could decline for numerous reasons, including decreased revenue received by state and local governments for spending on such projects, including federal funding. The most recent recession caused a nationwide decline in home sales and an increase in foreclosures, which correspondingly resulted in decreases in property taxes and some other local taxes, which are among the sources of funding for water and other critical infrastructure construction. State spending on infrastructure can be adversely affected by decreases or delays in, or uncertainties regarding, federal funding, which could adversely affect us.

See “Business — Our Industry” beginning on page 85 for a more detailed discussion of our markets and their funding sources.

We generate a significant portion of our revenue in California and adverse changes to the economy and business environment in the state has had an adverse effect on, and could continue to adversely affect, our operations, which could lead to lower revenue and reduced profitability.

Because of our geographic concentration in California, we are susceptible to fluctuations in our business caused by adverse economic or other conditions in the state, including natural or other disasters. A stagnant or depressed economy in California has in the past adversely affected, and could continue to adversely effect, our business and results of operations as well as the availability of state and local government funding.

As a result of the current importance of our California operations and anticipated continued growth from these operations, our revenue over the next several years is expected to be largely dependent on economic and regulatory conditions in California. If California experiences an economic downturn, or if the regulatory environment changes in a way that adversely affects our ability to do business or limits our competitive advantages, our profitability and growth prospects may be materially adversely affected. Similarly, due to our geographic concentration in California, a natural disaster or major event that disrupts these markets or the related workforce could have an immediate and material adverse impact on our operations and profitability.

We work in a highly competitive marketplace.

In the past, a majority of the contracts on which we bid were awarded through a competitive bid process, with awards generally being made to the lowest bidder, but sometimes recognizing other factors, such as shorter contract schedules or prior experience with the customer. For our design-build and other alternative methods of delivering projects, reputation, marketing efforts, quality of design and minimizing public inconvenience are also significant factors considered in awarding contracts, in addition to cost. Within our markets, we compete with many international, national, regional and local construction firms. Some of these competitors have achieved greater market penetration than we have in the markets in which we compete, and some may have greater financial and other resources than we do. In addition, there are a number of international and national companies in our industry that are larger than we are and that, if they so desire, could establish a presence in our markets and compete with us for contracts.

The cancellation of significant contracts or our disqualification from bidding for new contracts could reduce our revenue and profits and have a material adverse effect on our results of operations.

Contracts that we enter into with governmental entities can usually be canceled at any time by them with payment only for the work already completed. In addition, we could be prohibited from bidding on certain governmental contracts if we fail to maintain qualifications required by those entities. A cancellation of an unfinished contract or our debarment from the bidding process could cause our equipment and work crews to be idled for a significant period of time until other comparable work becomes available, which could have a material adverse effect on our business and results of operations.

An inability to obtain bonding could limit the aggregate dollar amount of contracts that we are able to pursue.

As is customary in the construction business, we are required to provide surety bonds to our customers to secure our performance under construction contracts. Our ability to obtain surety bonds primarily depends upon our capitalization, working capital, past performance, management expertise and reputation, as well as certain external factors, including the overall capacity of the surety market. Surety companies consider such factors in relationship to the amount of our backlog and their underwriting standards, which may change from time to time. Events that adversely affect the insurance and bonding markets generally may result in bonding becoming more difficult to obtain in the future, or being available only at a significantly greater cost. If we could no longer obtain adequate bonding or if the cost of bonding materially increased, it would limit the amount that we can bid on new contracts, limit the competitiveness of our bids, and could have a material adverse effect on our future revenue and business prospects.

27

For projects that existed prior to consummation of the AECOM Sale Transactions (“legacy projects”), our ability to obtain bonding may also be impacted by AECOM, who is the credit support provider for the surety bonds in place for all our legacy projects. See “— If AECOM defaults on its contractual obligations to us or under agreements in which we are a beneficiary, our business could be materially and adversely impacted.”

We are involved in ongoing disputes with our prior owner, AECOM, which could adversely impact our business.

We are involved in ongoing disputes with our prior owner, AECOM, which could adversely impact our business. The Purchase Agreement entered into in connection with the AECOM Sale Transactions provided for, among other things, the sharing with AECOM of a portion of our ultimate recoveries in respect of claims related to our work on certain legacy projects. With respect to one of these legacy project claims, we have obtained recovery, and AECOM has asserted that it is entitled to 80% of such amounts. The total amount AECOM is seeking to recover (and therefore the maximum amount we believe we could be liable for) is $40 million. We are disputing AECOM’s claim to such proceeds on the grounds that it fails to take into account the millions of dollars in losses that we had to fund following the closing of the AECOM Sale Transactions in respect of this project, the absence of which would have impaired our ability to obtain any recovery on such claim. We have also asserted counterclaims on behalf of SCC Group, LLC (“SCC Group”) alleging fraud by AECOM due to, among other things, material misrepresentations and omissions to SCC Group regarding the total value of the claim, the status of the project, and the amount of losses that would need to be funded in order to recover on account of such claim. These disputes remain ongoing and, if the parties cannot reach a resolution, it may result in a trial to determine whether and to what extent any portion of our recovery on the subject claim must be remitted to AECOM. Currently, the case is not expected to be adjudicated until 2025. While the ultimate outcomes of these disputes are uncertain, we do not believe that it will result in a material liability owed to AECOM. However, the outcomes of these disputes remain highly uncertain, and there can be no assurance that the court will agree with our position, or that we will not be liable for payment to Seller of the full amount asserted. For additional information regarding the AECOM Sale Transactions, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — AECOM Sale Transactions.”

We may be required to make additional payments to AECOM pursuant to contractual arrangements.

We may be required to make additional payments to our prior owner, AECOM, which could adversely impact our business. Pursuant to the Purchase Agreement entered into in connection with the AECOM Sale Transactions, we are required to make payments to the Seller Entities under certain circumstances. Potential payments to the Seller Entities set forth in the Purchase Agreement include potential payments for retained claim reimbursements from legacy projects, the payment of a portion of actual income tax benefits realized (i.e., in cash or through an actual reduction in liability for tax) as a result of AECOM’s election under Treasury Regulations Section 1.1502-36(d)(6) and a one-time additional cash payment if either of the Earnout Thresholds are achieved. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — AECOM Sale Transactions.”

In addition to the disputes regarding claim sharing described in “— We are involved in ongoing disputes with our prior owner, AECOM, which could adversely impact our business,” for which we could be required to make additional payments to AECOM, we are also pursuing claims relating to our work on another legacy project that was ongoing at closing of the AECOM Sale Transactions. To the extent we recover any amounts in respect of this claim, AECOM may be entitled to a percentage of the proceeds we receive, subject to a specified cap which takes into account, among other things, the amount of additional losses we are required to fund in order to realize maximum recovery in respect of this claim. As such payments are based on the outcome of future events, the amount of additional payments owed to AECOM (if any) is uncertain. If we are required to make such additional payments to AECOM under the Purchase Agreement, such payments could limit our cash flows or impair our ability to conduct business and pursue business strategies, which could have a material adverse effect on our results of operations, cash flows, or financial condition. Our ability, together with our subsidiaries, to make these additional payments may be affected by events beyond our and their control. Failure to comply with the

28

requirement for additional payments could result in an event of default under the Purchase Agreement, which, if not cured or waived could trigger cross-acceleration or cross-default provisions in other agreements.

With respect to the retained claim reimbursement described in the immediately preceding paragraph, the maximum exposure we could have to AECOM is unknown as it is dependent on a number of factors (including total losses funded and total claim recoveries), which will not be able to be determined until completion of the project which is ongoing. Based on our current loss position on this project, we do not expect to owe any money on this claim. To the extent we do owe money to AECOM on account of this claim, it will be satisfied from our ultimate realized recoveries from this project.

In addition to the above, in connection with the settlement of a dispute regarding the amount of the closing net working capital adjustment under the Purchase Agreement, we agreed to pay AECOM up to 10% of the amounts recoverable on account of a claim related a legacy project, up to maximum of $9.5 million. Accordingly, we maintain the full remaining amount, or $9.1 million, included in contingent consideration as of June 30, 2023. However, the amount ultimately payable to AECOM will depend on the amount actually recovered by us on account of the claim, which may be less than the amount accrued as of June 30, 2023. There is no guarantee we will be successful in recovering any amounts under the claim, in which case no amounts would be payable to AECOM relating to this matter.

None of the proceeds from the offering are expected to be used to make any payments that may be determined to be owed to AECOM.

If AECOM defaults on its contractual obligations to us or under agreements in which we are a beneficiary, our business could be materially and adversely impacted.

AECOM has provided corporate guarantees and other contractual obligations for our benefit. Specifically, AECOM has provided an irrevocable, limited and conditional guaranty to us in respect of receivables and claims relating to one project. If the final amounts collected by us in respect of this project (other than as a result of a voluntary settlement for which we do not obtain AECOM approval) is less than the applicable guaranteed amount, AECOM is contractually obligated to pay us the amount by which the specific guaranty amount for the project exceeds the total amounts collected by us in respect of the project. If we are required to seek payment from AECOM, and it does not fulfill its contractual obligation, our business could be materially and adversely impacted.

In addition, as our prior owner, AECOM is the credit support provider for the surety bonds in place for all our bonded projects that were ongoing as of the closing of the AECOM Sale Transactions. In the event AECOM were to experience financial distress and/or the bonding companies otherwise determined that the creditworthiness of AECOM was not sufficient, the underlying sureties could require that we provide additional credit support in the form of guarantees, letters of credit, collateral, or otherwise which could materially and adversely impact our business.

Similarly, if the applicable agreements relating to any of the foregoing AECOM-bonded projects require that the amount of the bond with respect to such project be increased, we will need to request that AECOM provide such an increase. In the event AECOM refuses to cooperate, the lack of required bonding could result in a default by us under the underlying project agreement as well as a right of the counterparty to terminate the underlying project agreement, any of which could materially and adversely impact our business.

Timing of the award and performance of new contracts could have an adverse effect on our results of operations and cash flows.

Historically, a substantial portion of our revenue and earnings is generated from large-scale project awards. The timing of project awards is unpredictable and outside of our control. Awards, including expansions of existing projects, often involve complex and lengthy negotiations and competitive bidding processes. These processes can be impacted by a wide variety of factors including a customer’s decision to not proceed with the development of a project, governmental approvals, financing contingencies, commodity prices, environmental conditions and overall market and economic

29

conditions. We may not win contracts that we have bid upon due to price, a customer’s perception of our ability to perform and/or perceived technology advantages held by others. Many of our competitors may be more inclined to take greater or unusual risks or terms and conditions in a contract that we might not deem acceptable. Because a significant portion of our revenue is generated from large projects, our results of operations can fluctuate quarterly and annually depending on whether and when large project awards occur and the commencement and progress of work under large contracts already awarded. As a result, we are subject to the risk of losing new awards to competitors or the risk that revenue may not be derived from awarded projects as quickly as anticipated.

The uncertainty of the timing of contract awards may also present difficulties in matching the size of our equipment fleet and work crews with contract needs. In some cases, we may maintain and bear the cost of more equipment and ready work crews than are currently required, in anticipation of future needs for existing contracts or expected future contracts. If a contract is delayed or an expected contract award is not received, we would incur costs that could have a material adverse effect on our anticipated profit.

In addition, the timing of the revenue, earnings and cash flows from our contracts can be delayed by a number of factors, including adverse weather conditions, such as prolonged or intense periods of rain, snow, storms or flooding, delays in receiving material and equipment from suppliers and services from subcontractors, labor shortages and changes in the scope of work to be performed. Such delays, if they occur, could have adverse effects on our results of operations for current and future periods until the affected contracts are completed.

Our participation in construction joint ventures exposes us to liability and/or harm to our reputation for failures of our partners.

As part of our business, we are a party to joint ventures, pursuant to which we typically jointly bid on and execute particular projects with other companies in the construction industry. Success on these joint projects depends upon managing the risks discussed in the various risks described in these “Risk Factors” and on whether our joint venture partners satisfy their contractual obligations.

We and our joint venture partners are generally jointly and severally liable for all liabilities and obligations of our joint ventures. If a joint venture partner fails to perform or is financially unable to bear its portion of required capital contributions or other obligations, including liabilities stemming from lawsuits, we could be required to make additional investments, provide additional services or pay more than our proportionate share of a liability to make up for our partner’s shortfall. Furthermore, if we are unable to adequately address our partner’s performance issues, the customer may terminate the project, which could result in legal liability to us, harm to our reputation and reduction to our profit on a project.

In connection with acquisitions, certain counterparties to joint ventures, which may include our historical direct competitors, may not desire to continue such arrangements with us and may terminate the joint ventures or not enter into new arrangements. Any termination of a joint venture could cause us to reduce our backlog and could materially and adversely affect our business, results of operations and financial condition.

Our dependence on a limited number of customers could adversely affect our business and results of operations.

Due to the size and nature of our construction contracts, one or a few customers have in the past and may in the future represent a substantial portion of our consolidated revenue and gross margin in any one year or over a period of several consecutive years. Similarly, our backlog frequently reflects multiple contracts for certain customers, therefore, one customer may comprise a significant percentage of backlog at a certain point in time. The loss of business from any one of such customers could have a material adverse effect on our business or results of operations. Also, a default or delay in payment on a significant scale by a customer could materially adversely affect our business, results of operations, cash flows and financial condition.

30

Strikes or work stoppages could have a negative impact on our operations and results.

We are party to collective bargaining agreements covering a majority of our craft workforce. Although all such collective bargaining agreements prohibit strikes and work stoppages, we cannot be certain that strikes or work stoppages will not occur despite the terms of these agreements. Strikes or work stoppages could adversely affect our relationships with our customers and cause us to lose business. Additionally, as current agreements expire, the labor unions may not be able to negotiate extensions or replacements on terms favorable to their members, or at all, or avoid strikes, lockouts or other labor actions from time to time that may affect their members.

Therefore, it cannot be assured that new agreements will be reached with employee labor unions as existing contracts expire, or on desirable terms. Any action against us relating to the union workforce we employ could have a material adverse effect on our business, financial condition, results of operations, profitability, cash flows and growth prospects. Overall, although strikes, work stoppages and other labor disputes have not had a significant impact on our operations or results in the past, such labor actions, or an inability to renew the collective bargaining agreements, could have a significant impact on our operations and results if they occur in the future.

Our dependence on subcontractors and suppliers of materials could increase our costs and impair our ability to complete contracts on a timely basis or at all, which would adversely affect our profits and cash flows.

We rely on third-party subcontractors to perform some of the work on many of our contracts. We also rely on third-party suppliers to provide most of the materials (including aggregates, cement, asphalt, concrete, steel, pipe, oil and fuel) for our contracts.

We generally do not bid on contracts unless we have commitments from suppliers for the materials and subcontractors for certain of the services required to complete the contract and at prices that we have included in our bid (except in some instances for trucking arrangements). Thus, to the extent that we cannot obtain commitments from our suppliers for materials and subcontractors for certain of the services, our ability to bid for contracts may be impaired. In addition, if a supplier or subcontractor is unable to deliver materials or services according to the negotiated terms of a supply/services agreement for any reason, including the deterioration of its financial condition, we may suffer delays and be required to purchase the materials or services from another source at a higher price or incur other unanticipated costs. This may reduce the profit to be realized, or result in a loss, on a contract.

Diesel fuel and other petroleum-based products are utilized to operate the plants and equipment on which we rely to perform our construction contracts. Future increases in the costs of fuel and other petroleum-based products used in our business, particularly if a bid has been submitted for a contract and the costs of such products have been estimated at amounts less than the actual costs thereof, could result in a lower profit, or a loss, on a contract.

An inability to secure sufficient aggregates could have a negative impact on our future results of operations.

We require aggregates (raw materials that are produced from natural sources and extracted from pits and quarries such as gravel, crushed stone and sand) in connection with our business. Strict governmental regulations and the limited number of properties containing useful aggregates have made it increasingly challenging and costly to obtain sufficient aggregates to support our business, both with respect to internal use and third-party sales. If we are unable to obtain aggregates to support our business, then our financial condition, results of operations and cash flows may be adversely affected.

Unavailability of insurance coverage could have a negative effect on our operations and results.

We maintain insurance coverage as part of our overall risk management strategy and pursuant to requirements to maintain specific coverage that are contained in our financing agreements and in most of our construction contracts. Although we have been able to obtain reasonably priced insurance coverage to meet our requirements in the past, there is no assurance that we will be able to do so in the future. For example, catastrophic events can

31

result in decreased coverage limits, more limited coverage and increased premium costs or deductibles. Our inability to obtain adequate insurance coverage could subject us to increased out-of-pocket expenses in the event of a claim and could have an adverse impact on our ability to procure new work, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Acquisition activity presents certain risks to our business, operations and financial condition, and we may not realize the financial and strategic goals contemplated at the time of a transaction.

We expect that acquisitions will be an important part of our long-term growth strategy. Successful execution following the closing of an acquisition is essential to achieving the anticipated benefits of the transaction. We expect to make acquisitions to expand into new markets and our acquisition strategy depends on our ability to complete and integrate the acquisitions. Mergers and acquisitions are inherently risky, and any mergers and acquisitions that we complete may not be successful. The process of integrating an acquired company’s business into our operations is challenging and may result in expected or unexpected operating or compliance challenges, which may require significant expenditures and a significant amount of our management’s attention that would otherwise be focused on the ongoing operation of our business. The potential difficulties or risks of integrating an acquired company’s business include, among others:

Our acquisitions may also result in the expenditure of available cash and amortization of expenses any of which could have a material adverse effect on our results of operations or financial condition. Investments in immature businesses with unproven track records have an especially high degree of risk, with the possibility that we may lose the value of our entire investments or incur additional unexpected liabilities. Large or costly acquisitions or investments may also diminish our capital resources and liquidity or limit our ability to engage in additional transactions for a period of time. All of the foregoing risks may be magnified as the cost, size or complexity of an acquisition or acquired company increases, or where the acquired company’s market or business are materially different from ours, or where more than one integration is occurring simultaneously or within a concentrated period of time.

In addition, in the future we may require significant financing to complete an acquisition or investment, whether through bank loans, raising of debt or otherwise. We cannot assure you that such financing options will be available to us on reasonable terms, or at all. If we are not able to obtain such necessary financing, it could have an impact on our ability to consummate a substantial acquisition or investment and execute our growth strategy. Alternatively, we may issue a significant number of shares as consideration for an acquisition, which would have a dilutive effect on our existing stockholders.

32

Amounts included in our backlog may not result in actual revenue or translate into profits. Our backlog is subject to cancellation and unexpected adjustments and therefore is an uncertain indicator of future results of operations.

Our backlog consists of the remaining unearned revenue on awarded contracts, including our pro-rata share of work to be performed by unconsolidated joint ventures, less the joint venture partners’ pro-rata share of work to be performed by consolidated joint ventures. We include in backlog estimates of the amount of consideration to be received, including bonuses, awards, incentive fees, fixed-price awards, claims, unpriced change orders, penalties, minimum customer commitments on cost plus arrangements, liquidated damages and certain time and material arrangements in which the estimated value is firm or can be estimated with a reasonable amount of certainty in both timing and amounts. As construction on our contracts progresses, we increase or decrease backlog to take account of changes in estimated quantities under fixed-price contracts, as well as to reflect changed conditions, change orders and other variations from initially anticipated contract revenue and costs, including completion penalties and bonuses. Substantially all of the contracts in our backlog may be canceled or modified at the election of the customer. As of June 30, 2023, our backlog was more than $1 billion. Most of our contracts are cancelable on short or no advance notice. Reductions in backlog due to cancellation by a customer, or for other reasons, could significantly reduce the revenue that we actually receive from contracts in backlog. In the event of a project cancellation, we may be reimbursed for certain costs, but we typically have no contractual right to the total revenue reflected in our backlog. Backlog amounts are determined based on target price estimates that incorporate historical trends, anticipated seasonal impacts, experience from similar projects and from communications with our customers. These estimates may prove inaccurate, which could cause estimated revenue to be realized in periods later than originally expected, or not at all. In the past, we have occasionally experienced postponements, cancellations and reductions in expected future work due to changes in our customers’ spending plans, as well as on construction projects, due to market volatility, regulatory and other factors. There can be no assurance as to our customers’ requirements or the accuracy of our estimates. As a result, our backlog as of any particular date is an uncertain indicator of future revenue and earnings. In addition, contracts included in our backlog may not be profitable. If our backlog fails to materialize, our business, financial condition, results of operations, profitability, cash flows and growth prospects could be materially and adversely affected.

The method of recognizing revenue over time using an input method based on costs incurred relative to total expected costs involves significant estimates which may result in material adjustments, which could result in a charge against our earnings.

We recognize contract revenue over time based on costs incurred. Under this method, estimated contract revenue are recognized by applying the percentage of completion of the project for the period based on the ratio of costs incurred to the total estimated costs at completion for the contract. If estimates of costs to complete fixed-price contracts indicate a loss, a provision is made through a contract write-down for the total loss anticipated. Total contract revenue and cost estimates are reviewed and revised at a minimum on a quarterly basis as the work progresses and as change orders are approved. Adjustments based upon the percentage of completion are reflected in contract revenue in the period when these estimates are revised. To the extent that these adjustments result in an increase or a reduction in or an elimination of previously reported contract profit, we recognize a credit or a charge against current earnings, as applicable. Such credits or charges could be material and could cause our results to fluctuate materially from period to period.

Accounting for our contract related revenue and costs, as well as other expenses, require management to make a variety of significant estimates and assumptions. Although we believe we have the experience and processes to enable us to formulate appropriate assumptions and produce reasonably dependable estimates, these assumptions and estimates are subject to the risks inherent in estimates, including unanticipated delays or technical complications. Variances in actual results from related estimates on a large project, or on several smaller projects, could be material. The full amount of an estimated loss on a contract is recognized in the period that our estimates indicate such a loss. Such adjustments and accrued losses could result in reduced profitability from a reversal of previously recorded revenue and profits, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

33

We may be required to make significant future contributions to multiemployer pension plans in which we participate.

We participate in various multiemployer pension plans in the United States under union agreements that generally provide defined benefits to employees covered by collective bargaining agreements. Absent an applicable exemption, a contributor to a U.S. multiemployer plan is liable, upon termination or withdrawal from a plan, for its proportionate share of the plan’s underfunded vested liability. Funding requirements for benefit obligations of these multiemployer pension plans are subject to certain regulatory requirements, and we may be required to make cash contributions that may be material to one or more of these plans to satisfy certain underfunded benefit obligations. As of December 30, 2022 and December 31, 2021, we recorded no liability for underfunding of multiemployer pension plans in which we participate, as no events triggering our obligation to make contributions for such underfunding were deemed probable to occur.

Debt agreements governing our current indebtedness contain, and debt agreements governing our future indebtedness may contain, certain covenants and other restrictions that may limit our ability to operate our business. Failure to comply with such covenants and other restrictions, or our inability to service any current indebtedness or future indebtedness, could adversely impact our business.

In March 2023, we entered into a Revolving Credit Facility (the “Revolving Credit Facility”) and in September 2023 we entered into a Loan and Security Agreement (the “Loan Agreement”). The terms of our existing debt agreements (including our Revolving Credit Facility, which we intend to repay with a portion of the proceeds from this offering) contain, and any debt agreements governing our future indebtedness may contain, a number of restrictive covenants and other provisions that impose significant operating and financial restrictions on us, including restrictions on our ability, and the ability of our subsidiaries, to take actions that may be in our best interests, including, among others, disposing of assets, entering into change of control transactions, mergers or acquisitions, incurring additional indebtedness, granting liens on our assets, declaring and paying dividends, and agreeing to do any of the foregoing. Our ability to meet financial covenants can be affected by events beyond our control, and we may not be able to continue to meet such covenants. A breach of any of these covenants or other restrictions or the occurrence of other events (including a material adverse effect or the inability to generate cash to service our obligations under our debt agreements) specified in our debt agreements could result in an event of default. Upon the occurrence of an event of default, our lenders could elect to declare all amounts outstanding, if any, to be immediately due and payable and terminate all commitments to extend further credit under our debt agreements. If we were unable to repay those amounts, we could be forced to curtail our operations, reorganize our capital structure (including through bankruptcy proceedings) or liquidate some or all of our assets in a manner that could adversely impact our business and cause holders of our securities to experience a partial or total loss of their investment in us.

We may need to raise additional capital in the future for working capital, capital expenditures and/or acquisitions, and we may not be able to do so on favorable terms or at all, which could impair our ability to operate our business or achieve our growth objectives.

Our ongoing ability to generate cash is important for funding our continuing operations, making acquisitions and servicing our indebtedness. To the extent that existing cash balances and cash flows from operations, together with borrowing capacity under our existing debt agreements, are insufficient to make investments or acquisitions or provide needed working capital, we may require additional financing from other sources. Our ability to obtain such additional financing in the future will depend in part on prevailing market conditions, as well as conditions in our business and our results of operations. Furthermore, if global economic, political or other market conditions adversely affect the financial institutions that provide credit to us, it is possible that our ability to draw upon our existing debt and credit facility may be impacted. If adequate funds are not available, or are not available on acceptable terms, we may not be able to make certain investments, take advantage of acquisitions or other opportunities, or respond to competitive challenges, each of which could have a material adverse impact on our business, financial condition, results of operations and cash flows.

34

We must manage our liquidity carefully to fund our working capital.

The need for working capital for our business varies due to fluctuations in the following amounts, among other factors:

We may have limited cash on hand and the timing of payments on our contract receivables is difficult to predict. If the timing of payments on our receivables is delayed or the amount of such payments is less than expected, our liquidity and ability to fund working capital could be materially and adversely affected.

Because our industry is capital-intensive and we have significant fixed and semi-fixed costs, our profitability is sensitive to changes in volume.

The property, plant and equipment needed to produce our products and provide our services can be very expensive. We must spend a substantial amount of capital to purchase and maintain such assets. Although we believe our current cash balance, along with our projected internal cash flows and available financing sources, will provide sufficient cash to support our currently anticipated operating and capital needs, if we are unable to generate sufficient cash to purchase and maintain the property, plant and equipment necessary to operate our business, or if the timing of payments on our receivables is delayed, we may be required to reduce or delay planned capital expenditures or to incur additional indebtedness. In addition, due to the level of fixed and semi- fixed costs associated with our business, volume decreases could have a material adverse effect on our financial condition, results of operations or liquidity.

We rely on information technology systems to conduct our business, and disruption, failure or security breaches of these systems could adversely affect our business and results of operations.

We rely on information technology (“IT”) systems in order to achieve our business objectives. We also rely upon industry accepted security measures and technology to securely maintain confidential information maintained on our IT systems. However, our portfolio of hardware and software products, solutions and services and our enterprise IT systems may be vulnerable to damage or disruption caused by circumstances beyond our control such as catastrophic events, power outages, natural disasters, computer system or network failures, computer viruses, cyber-attacks or other malicious software programs. The failure or disruption of our IT systems to perform as anticipated for any reason could disrupt our business and result in decreased performance, significant remediation costs, transaction errors, loss of data, processing inefficiencies, downtime, litigation and the loss of suppliers or customers. A significant disruption or failure could have a material adverse effect on our business operations, financial performance and financial condition.

We have implemented processes for systems under our control intended to mitigate risks, however, we can provide no guarantee that those risk mitigation measures will be effective. While we have historically been successful in defending against cybersecurity attacks and breaches, given the frequency of cybersecurity attacks and resulting breaches reported by other businesses and governments, it is likely we will experience one or more breaches of some extent in the future. We have incurred and may in the future incur significant costs in order to implement, maintain and/or update security systems we feel are necessary to protect our information systems, or we may miscalculate the level of investment necessary to protect our systems adequately. Since the techniques

35

used to obtain unauthorized access or to sabotage systems change frequently and are often not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventive measures.

Our business also requires us to share confidential information with suppliers and other third parties. Although we take steps to secure confidential information that is provided to third parties, such measures may not always be effective and data breaches, losses or other unauthorized access to or releases of confidential information may occur and could materially adversely affect our reputation, financial condition and results of operations and could result in liability or penalties under data privacy laws.

To the extent that any system failure, accident or security breach results in material disruptions or interruptions to our operations or the theft, loss or disclosure of, or damage to our data or confidential information, including our intellectual property, our reputation, business, results of operations and/or financial condition could be materially adversely affected.

Cybersecurity attacks on or breaches of our information technology environment could result in business interruptions, remediation costs and/or legal claims.

To protect confidential customer, vendor, financial and employee information, we employ information security measures that secure our information systems from cybersecurity attacks or breaches. Even with these measures, we may be subject to unauthorized access of digital data with the intent to misappropriate information, corrupt data or cause operational disruptions. If a failure of our safeguarding measures were to occur, or if software or third-party vendors that support our information technology environment are compromised, it could have a negative impact to our business and result in business interruptions, remediation costs and/or legal claims, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our business is seasonal and is affected by adverse weather conditions and the spending patterns of our customers, exposing us to variable quarterly results.

Some of our customers reduce their expenditures and work order requests towards the end of the fiscal year. Adverse weather conditions, particularly during the fall and winter seasons, can also affect our ability to perform outdoor services in certain regions. As a result, we generally experience reduced revenue in the first quarter of each fiscal year. Natural catastrophes such as hurricanes or other severe weather could also have a negative effect on the economy overall and on our ability to perform outdoor services in affected regions or utilize equipment and crews stationed in those regions, which could negatively affect our results of operations, cash flows and liquidity.

Pandemics and public health emergencies could materially disrupt our business and negatively impact our results of operations, cash flows and financial condition.

Pandemics and public health emergencies, such as the COVID-19 pandemic, may impact our results of operations, cash flows and financial condition in ways that are uncertain, unpredictable and outside of our control. The extent of the impact of such an event depends on the severity and duration of the public health emergency or pandemic, as well as the nature and duration of federal, state and local laws, orders, rules, emergency temporary standards, regulations and mandates, together with protocols and contractual requirements implemented by our customers, that may be enacted or newly enforced in response. Additionally, our ability to perform our work during such an event may be dependent on the governmental or societal responses to these circumstances in the markets in which we operate. A pandemic or public health emergency is likely to heighten and exacerbate the risks described herein. We experienced many of these risks in connection with the COVID-19 pandemic. Any resurgence of infection rates or the spread of new variants or viruses could trigger a return of many of the risks and circumstances we experienced in connection with the COVID-19 pandemic, which could adversely affect our revenue, results of operations, and cash flows.

We have recorded intangible assets that could become impaired and adversely affect our results of operations. Assessing whether impairment has occurred requires us to make significant judgments and assumptions about the future, which are inherently subject to risks and uncertainties, and if actual events turn out to be materially less favorable than the judgments we make and the assumptions we use, we may be required to record impairment charges in the future.

As of December 30, 2022 and December 31, 2021, our intangible assets recorded consisted of trademarks and customer contracts. We assess these assets for impairment annually, or more often if required. Our assessments involve a number of estimates and assumptions that are inherently subjective, require significant judgment and involve highly uncertain matters that are subject to change. The use of different assumptions or estimates could materially affect the determination as to whether or not an impairment has occurred. In addition, if future events are less favorable than what we assumed or estimated in our impairment analysis, we may be required to record an impairment charge, which could have a material adverse impact on our consolidated financial statements.

Both we and our customers use certain commodity products that are subject to significant price fluctuations. These fluctuations may have a material adverse effect on both our and our customers’ financial condition, results of operations and cash flows. Fluctuations in commodity prices may also affect our customers’ investment decisions and therefore subject us to risks of cancellation, delays in existing work, or changes in the timing and funding of new awards.

We are exposed to various commodity price risks, including, but not limited to, cement, steel, liquid asphalt, lumber, diesel fuel, natural gas and propane arising from transactions that are entered into in the normal course of business. We use petroleum based products, such as fuels, lubricants and liquid asphalt, to power or lubricate our equipment, operate our plants and as a significant ingredient in the asphaltic concrete we manufacture for sale to third parties and use in our asphalt paving construction projects. Although we are partially protected by asphalt or fuel price escalation clauses in some of our contracts, many contracts provide no such protection. We also use steel and other commodities in our construction projects that can be subject to significant price fluctuations. In order to manage or reduce commodity price risk, we monitor the costs of these commodities at the time of bid and price them into our contracts accordingly. Additionally, some of our contracts may include commodity price escalation clauses which partially protect us from increasing prices. Significant price fluctuations could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Commodity prices can also affect our customers in a number of ways. For example, for those customers that produce commodity products such as concrete, steel products, lumber and oil and gas, fluctuations in price can have a direct effect on their profitability and cash flows and, therefore, their willingness to continue to invest or make new capital investments. To the extent commodity prices decline or fluctuate and our customers defer new investments or cancel or delay existing projects, the demand for our services decreases, which may have a material adverse impact on our business, financial condition, results of operations and cash flows.

Rising inflation and/or interest rates could have an adverse effect on our business, financial condition and results of operations.

Economic factors, including inflation and fluctuations in interest rates, could have a negative impact on our business. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Risks Related to Legal and Governmental Regulation

Environmental laws and regulations and any changes to, or liabilities arising under, such laws and regulations could have a material adverse effect on our financial condition, results of operations and liquidity.

Our operations are subject to stringent and complex federal, state and local laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection and public health

37

and safety. These laws and regulations impose numerous obligations applicable to our operations, including requirements to obtain a permit or other approval before conducting regulated activities, restrictions on the types, quantities and concentration of materials that can be released into the environment, limitations on activities on certain lands lying within wilderness, wetlands and other protected areas, and assessments of substantial liabilities for pollution resulting from our operations. For example, a number of governmental bodies have finalized, proposed or are contemplating legislative and regulatory actions to reduce emissions of greenhouse gases, such as monitoring, reporting and emissions control requirements for certain large sources of greenhouse gases and greenhouse gas cap-and-trade programs. Because we emit greenhouse gases through the combustion of fossil fuels as part of our operations, any such laws and regulations applicable to jurisdictions in which we operate could require us to incur costs to reduce greenhouse gas emissions associated with our operations.

We have in the past been, and may in the future be, required to remediate contaminated properties currently or formerly owned or operated by us or third-party facilities that receive waste generated by our operations, regardless of whether such contamination resulted from our own actions or those of others and whether such actions complied with applicable laws at the time they were taken. In connection with certain acquisitions, we could assume, or be required to provide indemnification against, environmental liabilities that could expose us to material losses. Furthermore, the existence of contamination at properties that we own, lease or operate could result in increased operational costs or restrictions on our ability to use those properties as intended, including for mining purposes.

Numerous government authorities, such as the EPA and analogous state agencies, have the power to enforce compliance with these laws and the permits issued under them. Such enforcement actions often involve difficult and costly compliance measures or corrective actions. Certain environmental laws impose strict liability (i.e., no showing of “fault” is required) or joint and several liability for costs required to remediate and restore sites where hazardous substances, hydrocarbons or solid wastes have been stored or released. Failure to comply with these laws and regulations may result in the assessment of sanctions, including administrative, civil or criminal penalties, compensatory damages, the imposition of investigatory or remedial obligations, and the issuance of orders limiting or prohibiting some or all of our operations. In addition, we may experience delays in obtaining, or be unable to obtain, required permits, which may delay or interrupt our operations and limit our growth and revenue.

In certain instances, citizen groups also have the ability to bring legal proceedings against us if we are not in compliance with environmental laws, or to challenge our ability to receive environmental permits that we need to operate. In addition, claims for damages to persons or property, including natural resources, may result from the environmental, health and safety impacts of our operations. Our insurance may not cover all environmental risks and costs or may not provide sufficient coverage if an environmental claim is made against us. Moreover, public interest in the protection of the environment has increased dramatically in recent years. The trend of more expansive and stringent environmental legislation and regulations applied to our industry could continue, resulting in increased costs of doing business and, consequently, affecting profitability.

Our failure to comply with immigration laws could result in significant liabilities, harm our reputation with our customers and disrupt our operations.

Although we take steps to verify the employment eligibility status of all our employees, some of our employees may, without our knowledge, be unauthorized workers. Unauthorized workers are subject to deportation and may subject us to fines or penalties and, if any of our workers are found to be unauthorized, we could experience adverse publicity that could make it more difficult to hire and retain qualified employees. Termination of a significant number of unauthorized employees may disrupt our operations, cause temporary increases in our labor costs as we train new employees and result in additional adverse publicity. We could also become subject to fines, penalties and other costs related to claims that we did not fully comply with all recordkeeping obligations of federal and state immigration laws. If we fail to comply with these laws, our operations may be disrupted, and we may be subject to fines or, in extreme cases, criminal sanctions. In addition, many of our

38

customer contracts specifically require compliance with immigration laws, and, in some cases, our customers audit compliance with these laws. Further, several of our customers require that we ensure that our subcontractors comply with these laws with respect to the workers that perform services for them. Failure to comply with these laws or to ensure compliance by our subcontractors could damage our reputation and may cause our customers to cancel contracts with us or to not award future business to us. These factors could adversely affect our financial condition, results of operations and cash flows.

Our failure to comply with the regulations of OSHA and state and local agencies that oversee safety compliance could adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

The Occupational Safety and Health Act of 1970, as amended, establishes certain employer responsibilities, including maintenance of a workplace free of recognized hazards likely to cause death or serious injury, compliance with standards promulgated by OSHA and various recordkeeping, disclosure and procedural requirements. Various standards, including standards for notices of hazards and safety in excavation and demolition work, may apply to our operations. We have incurred, and will continue to incur, capital and operating expenditures and other costs in the ordinary course of business in complying with OSHA and other state and local laws and regulations, and could incur penalties and fines in the future, including, in extreme cases, criminal sanctions.

While we have invested, and will continue to invest, substantial resources in occupational health and safety programs, our industry involves a high degree of operational risk, and there can be no assurance that we will avoid significant liability. Although we have taken what we believe to be appropriate precautions, employees may suffer additional injuries in the future. Serious accidents of this nature may subject us to substantial penalties, civil litigation or criminal prosecution. Personal injury claims for damages, including for bodily injury or loss of life, could result in substantial costs and liabilities, which could materially and adversely affect our financial condition, results of operations or cash flows. In addition, if our safety record were to deteriorate, or if we suffered substantial penalties, adverse publicity or criminal prosecution for violation of health and safety regulations, customers could cancel existing contracts and not award future business to us, which could materially adversely affect our business, financial condition, results of operations, profitability, cash flows and growth prospects.

A change in tax laws or regulations of any federal or state jurisdiction in which we operate could increase our tax burden and otherwise adversely affect our business, financial condition, results of operations and cash flows.

We continue to assess the impact of various U.S. federal, state and international legislative proposals that could result in a material increase to our U.S. federal, state and/or international taxes. We cannot predict whether any specific legislation will be enacted or the terms of any such legislation. However, if such proposals were to be enacted, or if modifications were to be made to certain existing regulations, the consequences could have a material adverse impact on us, including increasing our tax burden, increasing our cost of tax compliance or otherwise adversely affecting our business, financial condition, results of operations and cash flows.

General Risk Factors

From time to time, we are involved in litigation proceedings, potential liability claims and contract disputes which may reduce our profits.

We may be subject to a variety of legal proceedings, liability claims or contract disputes. We engage in engineering and construction activities where design, construction or systems failures can result in substantial injury or damage. In addition, the nature of our business results in customers, subcontractors and suppliers occasionally presenting claims against us for recovery of costs they incurred in excess of what they expected to

39

incur, or for which they believe they are not contractually liable. We have been and may in the future be named as a defendant in legal proceedings where parties may make a claim for damages or other remedies with respect to our projects or other matters. In proceedings when it is determined that we have liability, we may not be covered by insurance or, if covered, the dollar amount of these liabilities may exceed our policy limits. In addition, even where insurance is maintained for such exposure, the policies have deductibles resulting in our assuming exposure for a layer of coverage with respect to any such claims. Any liability not covered by our insurance, in excess of our insurance limits or, if covered by insurance but subject to a high deductible, could result in a significant loss for us, and reduce our cash available for operations. In other legal proceedings, liability claims or contract disputes, we may be covered by indemnification agreements which may at times be difficult to enforce. Even if enforceable, it may be difficult to recover under these agreements if the indemnitor does not have the ability to financially support the indemnity. Litigation and regulatory proceedings are subject to inherent uncertainties, and unfavorable rulings could occur. If we were to receive an unfavorable ruling in a matter or fail to fully or promptly recover on any claims (including customer claims), our business and results of operations could be materially harmed for reasons such as a material adverse impact on our liquidity and financial results. In addition, litigation and other proceedings may take up management’s time and attention and take away from the time they are able to devote to other matters.

Although climate change and increasing regulations often drive demand for water infrastructure, climate change, and related legislative and regulatory responses to climate change, may have a long-term impact on our business.

Although we believe that we may benefit from initiatives seeking to address the effects of climate change, and we seek to mitigate our business risks associated with climate change by establishing robust environmental programs and partnering with organizations who are also focused on mitigating their own climate related risks, we recognize that there are inherent climate related risks wherever business is conducted. Access to clean water and reliable energy in the communities where we conduct our business is a priority and is not guaranteed. Any of these locations may be vulnerable to the adverse effects of climate change. For example, California, where we conduct a significant amount of business, has historically experienced, and is projected to continue to experience, climate-related events including drought and water scarcity, warmer temperatures, wildfires and air quality impacts and power shut-offs associated with wildfire prevention. Climate-related events, including the increasing frequency of extreme weather events and their impact on critical infrastructure in the U.S. and elsewhere, have the potential to disrupt our business, our third-party suppliers, and the business of our customers, and may cause us to experience higher attrition, losses and additional costs to maintain or resume operations.

Additionally, in many countries and jurisdictions, including the United States, governmental bodies are enacting new or additional legislation and regulations to reduce or mitigate the potential impacts of climate change. If we, our suppliers, or our customers are required to comply with these laws and regulations, or if we choose to take voluntary steps to reduce or mitigate our impact on climate change, we may experience increased costs for energy, production, transportation, and raw materials, increased capital expenditures, or increased insurance premiums and deductibles, which could adversely impact our operations. Inconsistency of legislation and regulations among jurisdictions may also affect the costs of compliance with such laws and regulations. Any assessment of the potential impact of future climate change legislation, regulations or industry standards is uncertain given the wide scope of potential regulatory change in the United States.

Physical, transition and regulatory risks related to climate change could have a material adverse impact on our business, financial condition and results of operations.

Physical risks related to climate change, such as changing sea levels, temperature fluctuations, severe storms, and energy and technological disruptions, could cause delays and increases in project costs, resulting in variability in our revenue and profitability, as well as potentially adverse impacts to our results of operations and financial condition. In addition, growing public concern about climate change has resulted in the increased focus of local, state, regional, national and international regulatory bodies on greenhouse gas emissions and climate change

40

issues. Legislation to regulate greenhouse gas emissions has periodically been introduced in the Congress and in the legislatures of various states in which we operate, and there has been a wide-ranging policy debate, both in the United States and internationally, regarding the regulation of greenhouse gas emissions. Such policy changes, including any enactment of increasingly stringent emissions or other environmental regulations, could increase the costs of projects for us and for our customers and, in some cases, delay or even prevent a project from going forward, thereby potentially reducing demand for our services. Consequently, this could have a material adverse effect on our business, financial condition and results of operations.

Deterioration of the United States economy could have a material adverse effect on our business, financial condition and results of operations.

To the extent that Congress is unable to lower United States debt substantially, a decrease in federal spending could result, which could negatively impact the ability of government agencies to fund existing or new infrastructure projects. In addition, such actions could have a material adverse effect on the financial markets and economic conditions in the United States as well as throughout the world, which may limit our ability and the ability of our customers to obtain financing and/or could impair our ability to execute our acquisition strategy. Deterioration in general economic activity and infrastructure spending or Congress’ deficit reduction measures could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We will incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives.

In addition to the increased cost we have incurred, and expect to continue to incur as an independent company following our separation from AECOM in January 2021, as a public company whose shares are listed on Nasdaq, we will incur additional accounting, legal and other expenses that we did not incur as a private company, including costs associated with our public company reporting requirements under the Exchange Act. We also anticipate that we will incur costs associated with corporate governance requirements, including requirements under Section 404 and other provisions of the Sarbanes-Oxley Act, as well as rules implemented by the SEC, the listing requirements of Nasdaq and other applicable securities rules and regulations. Compliance with these rules and regulations will increase our legal and financial compliance costs, introduce new costs, such as investor relations, stock exchange listing fees, stockholder reporting and directors and officers liability insurance, and will make some activities more time-consuming and costly. Furthermore, compliance with these rules will require a substantial investment of management’s time, and this investment may result in a diversion of management’s time and attention from revenue-generating activities. We are currently evaluating and monitoring developments with respect to these rules, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs, which are likely to be material.

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, creating additional legal and financial compliance costs and requiring additional investment of management’s time. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and additional costs necessitated by ongoing revisions to disclosure and governance practices. In addition, if our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us and our business may be adversely affected.

Risks Related to this Offering, the Securities Markets and Ownership of Our Common Stock

Our controlling stockholder will be able to exert substantial influence.

Following this offering, our controlling stockholder will beneficially own approximately  % of our outstanding shares of common stock (   % if the underwriters exercise their over-allotment option in full). As

41

a result, they could exert substantial influence over the outcome of any corporate matter submitted to our stockholders for approval, including the election of directors and any transaction that might cause a change in control, such as a merger or acquisition. Any stockholder in favor of a matter that is opposed by our controlling stockholder and members of our management would have to obtain a significant number of votes to overrule their votes. See “Principal Stockholders.”

Because we will be a “controlled company” under the listing standards of Nasdaq and the rules of the SEC, our stockholders may not have certain corporate governance protections that are available to stockholders of companies that are not controlled companies.

Following the completion of this offering, our controlling stockholder will continue to control a majority of the voting power of our outstanding common stock. As a result, although we do not expect to rely on the “controlled company” exemption, we will be a “controlled company” under the listing standards of Nasdaq and SEC rules, and we will qualify for exemptions from certain corporate governance requirements. Specifically, we will not be required to comply with certain provisions requiring that (i) a majority of our directors be independent, (ii) the compensation of our executives be determined by independent directors or (iii) nominees for election to our board of directors be selected by independent directors. If we elect to take advantage of some or all of these exemptions, our stockholders may not have the protections that these rules are intended to provide. Although we do not currently expect to rely on any of the “controlled company” exemptions, we may do so in the future. Our status as a “controlled company” could cause our common stock to be less attractive to certain investors or otherwise reduce the trading price of our common stock.

Prior to this offering, there has been no public market for our common stock, and we cannot assure you that a market for our common stock will develop or that the market price of shares of our common stock will not decline following the offering.

We cannot assure you that a trading market will develop for our common stock after this offering or, if one develops, that such trading market can be sustained. We intend to apply to have our common stock listed on Nasdaq, but we cannot assure you that our application will be approved. In addition, we cannot predict the prices at which our common stock will trade. The initial public offering price for our common stock will be determined through our negotiations with the underwriters based on numerous factors, including the information set forth in this prospectus, our prospects and the prospects of our industry, an assessment of our management, our prospects for future earnings, the general condition of the securities markets, the recent market prices of, and demand for, publicly traded common stock of generally comparable companies and other factors deemed relevant by the underwriters and us. Neither we nor the underwriters can assure you that the initial public offering price will bear any relationship to the market price at which our common stock may trade after our initial public offering. Shares of companies offered in an initial public offering often trade at a discount to the initial offering price due to underwriting discounts and commissions and related offering expenses.

We have broad discretion as to the use of the net proceeds from this offering and may not use them effectively.

We cannot specify with certainty the particular uses to which we will put the net proceeds from this offering. Our management will have broad discretion in the application of the net proceeds, and we may use these proceeds in ways with which you may disagree or for purposes other than those contemplated at the time of the offering. The failure by our management to apply these funds effectively could have a material adverse effect on our business, financial condition and results of operation. Pending their use, we may invest the net proceeds from this offering in a manner that does not produce income or that loses value. See “Use of Proceeds.”

The market price of our common stock may fluctuate significantly.

The market price and liquidity of the market for shares of our common stock that will prevail in the market after this offering may be higher or lower than the price you pay and may be significantly affected by numerous

42

factors, some of which are beyond our control and may not be directly related to our operating performance. These factors include:

Investors in this offering will experience immediate dilution upon the closing of the offering.

If you purchase shares of our common stock in this offering, you will experience immediate dilution of $    per share because the price that you pay will be greater than the pro forma net asset value per share of the common stock you acquire. This dilution is in large part due to the fact that our earlier investors paid substantially less than the initial public offering price when they purchased their shares. You may experience additional dilution if we issue shares of our common stock under the SCCI National Holdings, Inc. 2021 Stock Plan adopted in May 2021 (our “2021 Stock Plan”), the Shimmick Corporation 2023 Equity Incentive Plan (the “2023 Omnibus Incentive Plan”) we expect to adopt in connection with this offering or any other equity incentive plan, or we otherwise issue additional shares of our common stock at a price below the initial public offering price. For more information, see “Dilution” beginning on page 54.

If equity research analysts do not publish research or reports about our business, or if they issue unfavorable commentary or downgrade our shares, the price of our shares could decline.

The trading market for our shares will rely in part on the research and reports that equity research analysts publish about us and our business. We do not have control over these analysts, and we do not have commitments from them to write research reports about us. The price of our shares could decline if one or more equity research analysts downgrades our shares, issues other unfavorable commentary, or ceases publishing reports about us or our business.

Future sales of our shares could reduce the market price of our shares.

The price of our shares could decline if there are substantial sales of our common stock, particularly by our directors, our executive officers or their affiliates, or when there is a large number of shares of our common stock available for sale. The perception in the public market that our stockholders might sell our shares could also depress the market price of our shares. Our existing stockholder prior to this offering and members of our management team are subject to lock-up agreements with the underwriters that restrict their ability to transfer their shares for at least 180 days after the date of this prospectus. Consequently, upon expiration of the lock-up agreements,     additional shares will be eligible for sale in the public market (or     shares) if the underwriters exercise their over-allotment option in full). The market price of our shares may drop significantly when the restrictions on resale lapse and these stockholders are able to sell their shares into the market. If this

43

occurs or continues, it could impair our ability to raise additional capital through the sale of securities should we desire to do so. See “Shares Eligible for Future Sale” beginning on page 117.

Raising additional capital by issuing equity or equity-linked securities may cause dilution to our stockholders.

We may need or desire to raise substantial additional capital in the future. Our future capital requirements will depend on many factors, including, among others:

If we raise additional funds by issuing equity or equity-linked securities, we will reduce the percentage ownership of our then-existing stockholders, and the holders of those newly-issued equity or equity linked securities may have rights, preferences, or privileges senior to those possessed by our then-existing stockholders. Moreover, the existence of a substantial number of additional shares of common stock or other equity or equity-linked securities available for sale in the public market as a result of any such future capital raises could depress the market price of our common stock and impair our ability to conduct subsequent capital raises through the sale of further equity or equity-linked securities. We cannot predict the effect that future sales of our common stock or other equity or equity-linked securities would have on the market price of our common stock.

We do not anticipate paying any cash dividends in the foreseeable future after this offering. Therefore, if our share price does not appreciate, our investors may not experience gains and could potentially lose on their investment in our shares.

After this offering, we do not anticipate paying any cash dividends on our common stock in the foreseeable future. We currently intend to retain all available funds and any future earnings to fund the development and growth of our business. Any determination to pay dividends in the future will be at the discretion of our board of directors and will depend upon results of operations, financial condition, contractual restrictions, including any indebtedness we may incur, restrictions imposed by applicable law and other factors our board of directors deems relevant. As a result, capital appreciation, if any, of our shares will be investors’ sole source of gain for the foreseeable future.

Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to entrenchment of management.

Our amended and restated certificate of incorporation and amended and restated bylaws proposed to be in effect upon consummation of this offering will contain provisions that could significantly reduce the value of our shares to a potential acquirer or delay or prevent changes in control or changes in our management without the consent of our board of directors. The provisions in our charter documents will include the following:

44

In addition, these provisions would apply even if we were to receive an offer that some stockholders may consider beneficial.

We are also subject to the anti-takeover provisions contained in Section 203 of the Delaware General Corporation Law (“DGCL”). Under Section 203, a corporation may not, in general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years or, among other exceptions, our board of directors has approved the transaction. See “Description of Capital Stock”.

Our amended and restated charter documents will provide that the Court of Chancery of the State of Delaware (or if such court does not have jurisdiction, another state or the federal courts (as appropriate) located within the State of Delaware) will be the sole and exclusive forum for certain stockholder litigation matters, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees, or stockholders.

Our amended and restated charter documents will provide that unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or if such court does not have jurisdiction, another state or the federal courts (as appropriate) located within the State of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for any (i) derivative action or proceeding brought on our behalf, (ii) action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, or other employee, or stockholder of ours to us or our stockholders, (iii) action asserting a claim against us or any current or former director or officer of ours arising pursuant to any provision of the DGCL, or our amended and restated certificate of incorporation or our amended and restated bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, or (iv) action asserting a claim governed by the internal affairs doctrine of the State of Delaware. Our amended and restated certificate of incorporation further will provide that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the federal securities laws of the United States, including any claims under the Securities Act and the Exchange Act. However, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce a duty or liability created by the Securities Act or the rules and regulations thereunder and accordingly, we cannot be certain that a court would enforce such provision. See “Description of Capital Stock — Exclusive Forum.”

Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented to the forum provisions in our amended and restated charter documents, except our stockholders will not be deemed to have waived (and cannot waive) compliance with the federal securities laws and the rules and regulations thereunder. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our current or former directors, officers, other employees, or stockholders which may discourage lawsuits with respect to such claims. Alternatively, if a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, results of operations, and financial condition.

45

If, after this offering, we are unable to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act as it applies to an emerging growth company that is listed on an exchange for the first time, or if we are unable to maintain effective internal controls over financial reporting, investors may lose confidence in the accuracy of our financial statements and our share price may suffer.

After the completion of this offering, we will become subject to Section 404(a) of the Sarbanes-Oxley Act, which requires a company that is subject to the reporting requirements of the U.S. securities laws to conduct a comprehensive evaluation of its internal controls over financial reporting. To comply with this statute, we will be required to document and test our internal control procedures, and our management will be required to assess and report on the effectiveness of our internal controls over financial reporting. Although we will be required to disclose significant changes made in our internal controls and procedures on a quarterly basis, we will not be required to make our first report on the effectiveness of our internal control over financial reporting until the year following our first annual report required to be filed with the SEC.

We will need to prepare for initial compliance with Section 404(a) of the Sarbanes-Oxley Act by testing, assessing and, as necessary, strengthening our system of internal controls. Even after our initial assessment and report, we will need to test, assess and, as necessary, strengthen our internal controls on an annual basis. Furthermore, as our business continues to grow, our internal controls will become more complex and will require significantly more resources and attention to ensure that our internal controls remain effective overall. This process is complicated and time-consuming, and may divert management’s attention from revenue-generating activities. For so long as we continue to qualify as an emerging growth company or smaller reporting company, we will not be required to comply with Section 404(b) of the Sarbanes-Oxley Act, which requires a registered independent accounting firm to attest to and report on management’s assessment of its internal control over financial reporting. If we become subject to Section 404(b) of the Sarbanes-Oxley Act, we will incur additional expense in order to obtain the required attestation report.

Over the course of testing our internal controls, our management may identify material weaknesses, which may not be remediated in a timely manner to meet the deadline imposed by the Sarbanes-Oxley Act. A material weakness is a deficiency, or combination of deficiencies, in internal controls over financial reporting such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis.

In the course of preparing the financial statements that are included in this prospectus, our management has determined that we have material weaknesses in our internal control over financial reporting, which relates to the lack of a sufficient number of trained resources with assigned responsibilities and accountability for the design and operation of internal controls over financial reporting, lack of formal and effective controls over certain financial statement account balances, and lack of formal and effective controls over the Committee of Sponsoring Organizations (“COSO”) principles including control environment, risk assessment, control activities, information and communications and monitoring which resulted in material adjustments in the preparation of our condensed consolidated financial statements as of and for the six months ended June 30, 2023 and the consolidated financial statements for the fiscal years ended December 30, 2022 and December 31, 2021. In order to remediate these material weaknesses, we have hired and continue to seek out additional accounting and finance staff members with public company reporting experience, to augment our current staff and to improve the effectiveness of our closing and financial reporting processes. We are currently implementing key controls over financial reporting and COSO principles. While we have implemented a plan to remediate these material weaknesses, the steps we have taken to date, and that we are continuing to implement, may not be sufficient to remediate these material weaknesses or to avoid the identification of other material weaknesses in the future. If we fail to remediate the material weaknesses identified above in a timely manner or if we identify future deficiencies in our internal control over financial reporting, we may be unable to accurately report our financial results, or report them within the timeframes required by the SEC. We also could become subject to sanctions or investigations by the SEC or other regulatory authorities. In addition, if we are unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting, when required,

46

investors may lose confidence in the accuracy and completeness of our financial reports, we may face restricted access to the capital markets and our stock price may be adversely affected.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

Our disclosure controls and procedures are intended to be designed to reasonably assure that information required to be disclosed by us in reports we file or submit under the Exchange Act is accumulated and communicated to management, recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. These inherent limitations include the realities that there are judgments in decision-making, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements or insufficient disclosures due to error or fraud may occur and not be detected.

We are an emerging growth company and a smaller reporting company, and because we take advantage of specified reduced disclosure requirements applicable to emerging growth companies and smaller reporting companies, our financial statements may not be comparable to companies that comply with public company effective dates, which may make our common stock less attractive to investors.

We are an emerging growth company, as defined in the JOBS Act, and may remain an emerging growth company until the last day of the fiscal year following the fifth anniversary of the completion of this offering. However, if certain events occur prior to the end of such five-year period, including if we become a “large accelerated filer,” as defined under the Exchange Act, our annual gross revenue exceeds $1.235 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company. For so long as we remain an emerging growth company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include:

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of these accounting standards until they would otherwise apply to private companies. We have irrevocably elected to avail ourselves of this exemption and, therefore, we may not be subject to the same new or revised accounting standards as other public companies that are not emerging growth

47

companies. We intend to rely on other exemptions provided by the JOBS Act, including without limitation, not being required to comply with the auditor attestation requirements of Section 404(b) of Sarbanes-Oxley. Our financial statements may, therefore, not be comparable to those of companies that comply with such accounting standards and auditor attestation requirements. We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be reduced or more volatile.

We are also a smaller reporting company as defined in the Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as our voting and non-voting common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter, or our annual revenue is less than $100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter.

Our management has no prior experience operating a public company and therefore may have difficulty in successfully and profitably operating our business, or complying with regulatory requirements.

Prior to the closing of this offering, our management had no experience operating a public company. As a result, we cannot assure you that we will be able to successfully operate as a public company, execute our business strategies as a public company, or comply with regulatory requirements applicable to public companies.

USE OF PROCEEDS

We estimate that our net proceeds from the sale of shares of our common stock in this offering will be approximately $   million (or $   million if the underwriters exercise their over-allotment option in full), after deducting the underwriting discounts and commissions and our estimated offering expenses of approximately $   million (or approximately $   million if the underwriters exercise their over-allotment option in full). This estimate assumes a public offering price of $   per share, which is the mid-point of the offering price range indicated on the cover of this prospectus.

A $1.00 increase (decrease) in the assumed initial public offering price of $    per share of common stock, the midpoint of the estimated price range set forth on the cover page of this prospectus, would increase (decrease) the net proceeds to us from this offering by approximately $   million, assuming the number of shares of common stock offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting estimated underwriting discounts and commissions. Similarly, each increase (decrease) of 1,000,000 shares in the number of shares of common stock offered by us would increase (decrease) the net proceeds to us from this offering by approximately $   million, assuming the assumed initial public offering price of $   per share of common stock remains the same, and after deducting estimated underwriting discounts and commissions.

The principal purposes of this offering are to increase our capitalization and financial flexibility, create a public market for our common stock and facilitate our future access to the capital markets. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds we receive from this offering. However, we currently intend to use the net proceeds of this offering to repay all outstanding borrowings under our Revolving Credit Facility, with the remaining amounts for working capital and other general corporate purposes, including the potential funding of future opportunistic acquisitions. Currently, no specific acquisition targets have been identified and we do not have agreements or commitments to enter into any acquisitions. In the event that any net proceeds are not immediately applied, we may temporarily hold them as cash, deposit them in banks or invest them in cash equivalents or securities.

As of June 30, 2023, there was $30.0 million of borrowings outstanding under our Revolving Credit Facility. The Revolving Credit Facility bears interest at an annual rate of adjusted term SOFR, subject to a 1.0% floor, plus 4.50%, and matures on March 27, 2028. The proceeds from the Revolving Credit Facility were used for general corporate purposes.

For additional information, please read “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources.”

51

DIVIDENDS AND DIVIDEND POLICY

We currently intend to retain all available funds and future earnings, if any, to fund the development and expansion of our business, and we do not anticipate paying any additional cash dividends in the foreseeable future. Any future determination regarding the declaration and payment of dividends, if any, will be at the discretion of our board of directors and will depend on then-existing conditions, including our financial condition, results of operations, contractual restrictions, capital requirements, business prospects and other factors our board of directors may deem relevant.

52

CAPITALIZATION

The following table sets forth the cash and cash equivalents and capitalization as of June 30, 2023 (i) on an actual basis and (ii) on a pro forma basis to give effect to (a) the filing and effectiveness of our proposed amended and restated certificate of incorporation, including to increase our authorized share capital, (b) the  for     stock split of our common stock and (c) the sale by us of     shares of our common stock in this offering at an assumed initial public offering price of $    per share (which is the midpoint of the price range set forth on the cover page of this prospectus) after deducting estimated underwriting discounts and commissions and offering expenses paid by us and the application of the net proceeds from this offering to us as described under “Use of Proceeds,” in each case, as if such event had occurred on June 30, 2023.

You should read this information together with our consolidated financial statements and related notes appearing elsewhere in this prospectus and the sections titled “Prospectus Summary — Summary Selected Consolidated Financial Data” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” The following amounts are in thousands, except per share data.

Each $1.00 increase or decrease in the assumed initial public offering price of $  per share, the midpoint of the price range set forth on the cover page of this prospectus, would increase or decrease, respectively, the amount of cash and cash equivalents, additional paid-in capital, total stockholders’ equity and total capitalization by $  million, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We may also increase or decrease the number of shares we are offering.

An increase or decrease of 1,000,000 in the number of shares we are offering would increase or decrease, respectively, the amount of cash and cash equivalents, stockholders’ equity and total capitalization by approximately $  million, assuming the assumed initial public offering price per share remains the same, and after deducting underwriting discounts and commissions. The pro forma information is illustrative only, and we will adjust this information based on the actual initial public offering price and other terms of this offering determined at pricing.

53

DILUTION

If you invest in our common stock in this offering, your interest will be diluted to the extent of the difference between the initial public offering price per share of our common stock and the pro forma net tangible book value per share of our common stock immediately after the closing of this offering.

Our net tangible book value of our common stock as of June 30, 2023 was $    million, or $    per share, based on the number of shares of our common stock outstanding as of June 30, 2023. Net tangible book value per share represents our total tangible assets less our total liabilities, divided by the number of outstanding shares of common stock.

After giving effect to the receipt of the net proceeds from our sale of     shares of common stock in this offering at an assumed initial public offering price of $    per share, the midpoint of the price range set forth on the cover page of this prospectus, after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma net tangible book value as of June 30, 2023, would have been $    million, or $     per share. This represents an immediate increase in pro forma net tangible book value of $    per share to our existing stockholder and an immediate dilution of $    per share to investors purchasing common stock in this offering.

We calculate dilution per share to new investors by subtracting the pro forma net tangible book value per share from the initial public offering price paid by the new investor. The following table illustrates the dilution to new investors on a per share basis:

Each $1.00 increase (decrease) in the assumed initial public offering price of $   would increase (decrease) our pro forma net tangible book value per share after this offering by $   per share and the dilution to new investors by $   per share, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

Similarly, each increase (decrease) of 1,000,000 shares in the number of shares of common stock offered by us would increase (decrease) the pro forma net tangible book value by $   per share and the dilution to new investors by $   per share, assuming the assumed initial public offering price remains the same and after deducting underwriting discounts and commissions.

If the underwriters’ option to purchase additional shares to cover over-allotments is exercised in full, the pro forma net tangible book value per share after giving effect to this offering would be $   per share, representing an immediate increase to existing stockholder of $   per share, and immediate dilution to new investors in this offering of $   per share.

The foregoing discussion and tables assume no exercise of stock options to purchase    shares of our common stock issuable upon the exercise of stock options outstanding as of     , 2023, at a weighted average exercise price of $   per share. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities or any options are exercised, new investors will experience further dilution.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to assist in understanding and assessing the trends and significant changes in our results of operations and financial condition. Historical results may not be indicative of future performance. The statements in this discussion regarding industry outlook, our expectations regarding our future performance, liquidity and capital resources and all other non-historical statements in this discussion are forward looking statements and are based on the beliefs of our management, as well as assumptions made by, and information currently available to, our management. Actual results could differ materially from those discussed in or implied by forward looking statements as a result of various factors, including those discussed below and elsewhere in this prospectus, particularly in “Risk Factors” or in other sections of this prospectus. This discussion should be read in conjunction with “Prospectus Summary — Summary Selected Consolidated Financial Data” and our unaudited condensed consolidated and audited consolidated financial statements and the notes thereto included elsewhere in this prospectus.

In this discussion, we use certain non-GAAP financial measures. Explanation of these non-GAAP financial measures and reconciliation to the most directly comparable GAAP financial measures are included in this Management’s Discussion and Analysis of Financial Condition and Results of Operations as well as “Prospectus Summary — Summary Selected Consolidated Financial Data.” Investors should not consider non-GAAP financial measures in isolation or as substitutes for financial information presented in compliance with GAAP.

Overview

We are a leading provider of water and other critical infrastructure solutions nationwide. Through our predecessor entities we have a long history of working on complex water projects, ranging from the world’s largest wastewater recycling and purification system in California to the iconic Hoover Dam. According to Engineering News Record, in 2022 we were nationally ranked as a top ten builder of dams and reservoirs (#1), water supply (#3), water treatment and desalination plants (#8) and mass transit (#9). We are led by industry veterans, many with over 20 years of experience, and work closely with our customers to deliver complete solutions, including long-term operations and maintenance.

While our legacy companies have a long history operating in the United States, we have a limited operating history as an independent company. Following our separation from AECOM, we began a transformation to shift our strategy to meet the nation’s growing need for water and other critical infrastructure. We believe our competitive strengths, which are discussed below, position us to execute this strategy and capitalize on market opportunities. However, our limited operating history as an independent company and historical dependence on AECOM and subject us to a number of risks, such as an inability to obtain necessary bonding and the need to incur additional operating expenses to create or supplement the corporate infrastructure necessary to operating as an independent company. We are also involved in ongoing disputes with AECOM, which could adversely impact our business. See “— AECOM Sale Transactions” and “Risk Factors — Risks Related to our Projects — We have a limited operating history as an independent company and have been historically dependent on our prior owner, AECOM, “— Risks Related to Our Business and Industry — We are involved in ongoing disputes with our prior owner, AECOM, which could adversely impact our business,” “— We may be required to make additional payments to AECOM pursuant to contractual arrangements” and “— If AECOM defaults on its contractual obligations to us or under agreements in which we are a beneficiary, our business could be materially and adversely impacted” for additional information.

For the six months ended June 30, 2023 and July 1, 2022, we generated revenue of $319.3 million and $293.6 million, respectively, and net (loss) income attributable to Shimmick Corporation of $(19.6) million and $3.7 million, respectively. Adjusted EBITDA, was $(2.9) million and $31.9 million for the six months ended June 30, 2023 and July 1, 2022, respectively. Adjusted net (loss) attributable to Shimmick Corporation income was $(12.0) million and $22.7 million for the six months ended June 30, 2023 and July 1, 2022, respectively. For

55

the years ended December 30, 2022 and December 31, 2021, we generated revenue of $664.2 million and $572.7 million, respectively, and net income attributable to Shimmick Corporation of $3.8 million and $45.4 million, respectively. Adjusted EBITDA was $47.0 million and $(193.6) million for the years ended December 30, 2022 and December 31, 2021, respectively. Adjusted net income (loss) was $29.5 million and ($184.3) million for the years ended December 30, 2022 and December 31, 2021, respectively. For reconciliations of Adjusted EBITDA and Adjusted net (loss) income to net income, in each case the most directly comparable GAAP financial measure, see “— Results of Operations” below.

We operate on a 52-week or 53-week fiscal year ending on the Friday closest to December 31 each year. Our fiscal year is divided into four quarters of 13 weeks, each beginning on a Saturday and containing one 5-week period followed by two 4-week periods. When a 53-week fiscal year occurs, we report the additional week in the fourth fiscal quarter. Accordingly, the six month periods ended June 30, 2023 and July 1, 2022 each consisted of 26 weeks. References to fiscal year 2022 are to our 52-week fiscal year ended December 30, 2022 and references to fiscal year 2021 are to our 52-week fiscal year ended December 31, 2021.

AECOM Sale Transactions

Overview

On December 9, 2020, AECOM and URS Holdings, Inc., an affiliate of AECOM (the “Seller” and, together with AECOM, the “Seller Entities”), entered into a purchase and sale agreement (the “Purchase Agreement”) with SCC Group, a special purpose entity formed for the purpose of entering into and consummating the transactions contemplated by the Purchase Agreement (the “AECOM Sale Transactions”). Under the Purchase Agreement, SCC Group agreed to purchase and acquire 100% of the stock of the Company and certain other assets related to our business and our subsidiaries to the extent owned by Seller Entities or their affiliates. On January 2, 2021, the parties closed the AECOM Sale Transactions.

On November 19, 2021, SCC Group was merged with SCCI National Holdings, Inc., with SCCI National Holdings, Inc. becoming the surviving entity. In the intervening period between January 2, 2021 and November 19, 2021, SCC Group’s assets and liabilities consisted of its investment in SCCI National Holdings, Inc., as well as rights to receive any net working capital settlement and any obligation to pay contingent consideration related to its January 2, 2021 acquisition of SCCI National Holdings, Inc. The November 19, 2021 merger of SCC Group with SCCI National Holdings, Inc. was accounted for as a combination of entities under common control. Accordingly, results of the operations of the two entities have been combined from the point when they came under common control (i.e., when SCC Group acquired SCCI National Holdings, Inc. on January 2, 2021). The business combination is thus reflected in the consolidated financial statements of the combined company for the year ended December 31, 2021. SCC Group did not have substantive operations, assets or liabilities prior to the merger with SCCI National Holdings, Inc. except those pertaining to its acquisition of the SCCI National Holdings, Inc. business.

Retained Claim Reimbursements

The Purchase Agreement provides that the Seller Entities will retain the right to participate in a portion of the net proceeds of any cash, cash equivalents or other assets received or recovered from any claims relating to certain specified legacy projects that were ongoing at the time of closing. AECOM is entitled to a percentage of proceeds we may receive, subject to a specified cap for each such legacy project.

Earn Out Consideration

As additional consideration, the Seller Entities are entitled to receive a one-time additional cash payment based on the performance of the business for the 36-month period beginning October 3, 2020 and ending September 29, 2023 based on specified aggregate Adjusted EBITDA (as defined in the Purchase Agreement) thresholds set forth in the Purchase Agreement. Any such additional cash payment, if owed, will be required to be made prior to

56

January 31, 2024. Based on the Adjusted EBITDA (as defined in the Purchase Agreement) of the business to date, we do not anticipate an earnout being achieved.

Shared Tax Benefits

Pursuant to the internal reorganization of its business in early 2020, AECOM agreed to make an election under Treasury Regulations Section 1.1502-36(d)(6) that could result in certain tax benefits to us (in the form of cash or a reduction in liability for taxes). We are obligated to share with AECOM actual tax benefits realized (i.e., in cash or through an actual reduction in liability for tax).

Other Items

We have agreed to indemnify the Seller Entities for any costs or expenses incurred under any outstanding letters of credit, surety bonds, guarantees, advance payment guarantees and other contractual obligations arising from or relating to the assets purchased or the liabilities assumed under the Purchase Agreement. Further, the Seller Entities have provided a conditional guaranty required by any surety bonds and/or a bonding program relating to certain guaranteed obligations and payment obligations with respect to the certain other assets related to our business and our subsidiaries to the extent owned by Seller Entities or their affiliates.

For additional information regarding AECOM, see “Risk Factors — Risks Related to Our Business and Industry — We are involved in ongoing disputes with our prior owner, AECOM, which could adversely impact our business,” “— We may be required to make additional payments to AECOM pursuant to contractual arrangements,” “— If AECOM defaults on its contractual obligations to us or under agreements in which we are a beneficiary, our business could be materially and adversely impacted” and “Business — Transition Services Agreement.”

COVID-19 Impact

The impact of the coronavirus pandemic and measures to prevent its spread caused us to face disruption to operations, supply chain delays, travel and trade restrictions and impacted economic activity in affected regions. For example, some jurisdictions imposed a wide range of restrictions on the physical movement of our employees and vendors to limit the spread of COVID-19 and some nonessential construction and other client projects were temporarily halted as a result. Further, the coronavirus made estimating the future performance of our business and mitigating the adverse financial impact of related developments on our business operations more difficult. See “Risk Factors—Risks Related to our Business and Industry — Pandemics and public health emergencies could materially disrupt our business and negatively impact our results of operations, cash flows and financial conditions.”

Key Factors Affecting Our Performance and Results of Operations

Weather, natural disasters and emergencies. The results of our business in a given period can be impacted by adverse weather conditions, severe weather events, natural disasters or other emergencies, which include, among other things, heavy or prolonged snowfall or rainfall, hurricanes, tropical storms, tornadoes, floods, blizzards, extreme temperatures, wildfires, post-wildfire floods and debris flows, pandemics and earthquakes. These conditions and events can negatively impact our financial results due to, among other things, the termination, deferral or delay of projects, reduced productivity and exposure to significant liabilities. See “Risk Factors — Risks Related to Our Projects — Adverse weather conditions may cause delays, which could slow completion of our contracts and negatively affect our revenue and cash flows” and “— Force majeure events, such as natural disasters, epidemics, pandemics and terrorists’ actions, could negatively impact our business, which may affect our financial condition, results of operations or cash flows.”

Seasonality. Typically, our revenue is lowest in the first quarter of the year because cold, snowy or wet conditions can create challenging working environments that are more costly for our customers or cause delays

57

on projects. Second quarter revenue is typically higher than those in the first quarter, as some projects begin, but continued cold and wet weather can often impact productivity. Third quarter revenue is typically the highest of the year, as a greater number of projects are underway and operating conditions, including weather, are normally more accommodating. Project geographic location will also dictate how seasonality affects productivity and timing. Also, the holiday season and inclement weather can sometimes cause delays during the fourth quarter, reducing revenue and increasing costs. See “Risk Factors — Risks Related to Our Business and Industry — Our business is seasonal and is affected by adverse weather conditions and the spending patterns of our customers, exposing us to variable quarterly results.”

Our Ability to Fulfill Backlog Orders. Our backlog consists of the remaining unearned revenue on awarded contracts, including our pro-rata share of work to be performed by unconsolidated joint ventures, less the joint venture partners’ pro-rata share of work to be performed by consolidated joint ventures. We include in backlog estimates of the amount of consideration to be received, including bonuses, awards, incentive fees, fixed-price awards, claims, unpriced change orders, penalties, minimum customer commitments on cost plus arrangements, liquidated damages and certain time and material arrangements in which the estimated value is firm or can be estimated with a reasonable amount of certainty in both timing and amounts. As construction on our contracts progresses, we increase or decrease backlog to take account of changes in estimated quantities under fixed-price contracts, as well as to reflect changed conditions, change orders and other variations from initially anticipated contract revenue and costs, including completion penalties and bonuses. Substantially all of the contracts in our backlog may be canceled or modified at the election of the customer. Reductions in backlog due to cancellation by a customer, or for other reasons, could significantly reduce the revenue that we actually receive from contracts in backlog. In the event of a project cancellation, we may be reimbursed for certain costs, but we typically have no contractual right to the total revenues reflected in our backlog. Backlog amounts are determined based on target price estimates that incorporate historical trends, anticipated seasonal impacts, experience from similar projects and from communications with our customers. These estimates may prove inaccurate, which could cause estimated revenue to be realized in periods later than originally expected, or not at all. As a result, our backlog as of any particular date is an uncertain indicator of future revenue and earnings. In addition, contracts included in our backlog may not be profitable. If our backlog fails to materialize, our business, financial condition, results of operations and cash flows could be materially and adversely affected. See “Risk Factors — Risks Related to Our Projects — Amounts included in our backlog may not result in actual revenue or translate into profits. Our backlog is subject to cancellation and unexpected adjustments and therefore is an uncertain indicator of future results of operations.”

As of June 30, 2023, we had a backlog of projects of $1.3 billion, approximately $142 million, or 11%, of which are through our joint venture arrangements. We estimate that approximately $1.0 billion will be recognized as revenue over the next twenty four months. None of our backlog is subject to AECOM contractual obligations. Our backlog by customer type, contract type and estimated time periods recognized is presented in the following tables:

58

Our Ability to Obtain New Projects. We selectively bid on projects that we believe offer an opportunity to meet our profitability objectives or that offer the opportunity to enter promising new markets. The potential customers conduct rigorous competitive processes for awarding many contracts. We will potentially face strong competition and pricing pressures for any additional contract awards from other government agencies, and we may be required to qualify or continue to qualify under various multiple award task order contract criteria. See “Risk Factors — Risks Related to Our Projects — Our business depends on our ability to qualify as an eligible bidder under federal, state or local government contract criteria and to compete successfully against other qualified bidders in order to obtain federal, state or local government contracts,” “Risk Factors — Risks Related to Our Business and Industry — We work in a highly competitive marketplace” and “— Pandemics and public health emergencies could materially disrupt our business and negatively impact our results of operations, cash flows and financial condition.”

Our Ability to Successfully Expand our Footprint. We review our bidding opportunities to attempt to minimize concentration of work with any one customer, in any one industry, or in tight labor markets. We believe that by carefully positioning ourselves in markets that have meaningful barriers to entry, like those with highly technical or specialized scopes of work, we can continue to be competitive. For example, we target projects with significant, highly-technical work that we can self-perform. We believe this provides us with a distinct pricing advantage, as well as better risk management. In addition, as a result of federal and state-level infrastructure initiatives, we believe that funding for technical construction projects may exceed capacity, enabling us to opportunistically target smaller specialized projects with less risk at higher margins. We may be limited in our ability to expand our footprint by barriers to entry to new markets, competition, and availability of capital and skilled labor.

We primarily compete for new contracts independently, seeking to win and complete new projects directly for our customers. Our customers primarily award contracts using one of two methods: the traditional public “competitive bid” method, in which price is the major determining factor, or through a “best value” proposal, where contracts are awarded based on a combination of technical qualifications, proposed project team, schedule, the ability to obtain surety bonds, past performance on similar projects and price, which we believe creates a barrier to entry. Contracts are principally awarded on a fixed-price basis, and we earn and recognize revenue using an input measure of total costs incurred divided by total costs expected to be incurred. See “Risk Factors — Risks Related to Our Projects — Our business depends on our ability to qualify as an eligible bidder under federal, state or local government contract criteria and to compete successfully against other qualified bidders in order to obtain federal, state or local government contracts” and “Risk Factors — Risks Related to Our Business and Industry — We work in a highly competitive marketplace.”

Our Ability to Obtain Approval of Change Orders and Successfully Pursue Claims. We are subject to variation in scope and cost of projects from our original projections. In certain circumstances, we seek to collect or assert claims against customers, engineers, consultants, subcontractors or others involved in a project for additional costs exceeding the contract price or for amounts not included in the original contract price. Our experience has often been that public customers have been willing to negotiate equitable adjustments in the contract compensation or completion time provisions if unexpected circumstances arise. However, this process may result in disputes over whether the work performed is beyond the scope of the work included in the original project plans and specifications or, if the customer agrees that the work performed qualifies as extra work, the price that the customer is willing to pay for the extra work. Public customers may seek to impose contractual risk-shifting provisions more

aggressively or there could be statutory and other legal prohibitions that prevent or limit contract changes or equitable adjustments. See “Risk Factors — Risks Related to Our Projects — Our failure to adequately collect for extra or change order work or recover on claims brought by us against customers or other project participants for additional contract costs could have a negative impact on our liquidity and future operations.”

Our Ability to Control Project Costs. Our costs primarily consist of payroll, equipment, materials, and other project related expenses. With a consistent focus on profitability by our management team, we leverage information technology and utilize financial systems to improve project execution and control costs. However, if we are unable to accurately estimate the overall risks, requirements or costs when we bid on or negotiate a contract that is ultimately awarded to us, we may achieve a lower than anticipated profit or incur a loss on the contract. Also, our labor and training expenses may increase as a result of a shortage in the supply of skilled personnel. We may not be able to pass these expenses on to our customers, which could adversely affect our profitability. To the extent that we are unable to buy construction equipment necessary for our needs, either due to a lack of available funding or equipment shortages in the marketplace, we may be forced to rent equipment on a short-term basis, which could increase the costs of performing our contracts. If we are unable to continue to maintain the equipment in our fleet, we may be forced to obtain third-party repair services, which could increase our costs. In addition, the market value of our equipment may unexpectedly decline at a faster rate than anticipated. See “Risk Factors — Risks Related to Our Projects — We may incur higher costs to lease, acquire and maintain equipment necessary for our operations, and the market value of our owned equipment may decline.”

Our Ability to Control Selling General and Administrative Costs. Following our initial public offering, we will incur significant expenses on an ongoing basis that we did not incur as a private company. Those costs include additional director and officer liability insurance expenses, stock exchange listing expenses, as well as third-party and internal resources related to accounting, auditing, Sarbanes-Oxley Act compliance, legal and investor and public relations expenses. These costs will generally be selling, general and administrative expenses. We plan to implement the 2023 Omnibus Incentive Plan to align our equity compensation program with public company plans and practices, which is expected to increase our stock-based compensation expense. See “Risk Factors — General Risk Factors — We will incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives.”

How We Assess Performance of Our Business

Revenue

We currently derive our revenue predominantly by providing construction, operations and management services around the United States. We generally recognize revenue over time as performance obligations are satisfied and control over promised goods or services are transferred to our customers.

Gross Margin

Gross margin represents revenue less cost of revenue. Cost of revenue consist of all direct and indirect costs on construction contracts, including raw materials, labor, equipment costs, and subcontractor costs.

Selling, General, and Administrative Expenses

Selling, general and administrative expenses consist primarily of salaries and personnel costs for our administrative, finance and accounting, legal, information systems, human resources and certain managerial employees. Additional expenses include audit, consulting and professional fees, travel, insurance, office space rental costs, property taxes and other corporate and overhead expenses.

Equity in earnings of unconsolidated joint ventures includes our return on investment in unconsolidated joint ventures.

Results of Operations

Six Months Ended June 30, 2023 Compared to the Six Months Ended July 1, 2022

The following table sets forth selected financial data for the six months ended June 30, 2023 compared to the six months ended July 1, 2022:

Net (loss) income

Net income decreased by $22.7 million to a $19.6 million net loss for the six months ended June 30, 2023 compared to $3.1 million in net income for the six months ended July 1, 2022, primarily driven by a lower equity in earnings of unconsolidated joint ventures of $31.8 million and an increase in selling, general and administrative expenses of $3.6 million. These decreases were partially offset by a $9.3 million reduction in other expense, net and a higher gross margin of $0.4 million for the six months ended June 30, 2023.

Revenue

Revenue for the six months ended June 30, 2023 increased $25.7 million, or 9%, compared to six months ended July 1, 2022 primarily due to $54.0 million in new activity from eight new projects. Those increases were partially offset by $24.6 million driven by three projects winding down and nearing completion and an agreed upon contract settlement lower than originally estimated.

61

Cost of revenue

Cost of revenue for the six months ended June 30, 2023 increased $25.3 million, or 9%, compared for the six months ended July 1, 2022 primarily due to a $45.4 million increase in activity from seven new projects and an increased $5.9 million from a new terminal project that experienced losses during the period. Those increases were partially offset by $17.2 million decrease in costs on projects winding down or nearing completion in fiscal year 2022 and $6.4 million decreases in cost due mainly to $4.0 million of additional cost taken on a large bridge project for the six months ended July 1, 2022 that did not occur in the six months ended June 30, 2023.

Selling, general and administrative expenses

Selling, general and administrative expense for the six months ended June 30, 2023 increased by $3.6 million, or 12%, to $32.5 million compared to $28.9 million for the six months ended July 1, 2022, primarily resulting from higher legal, accounting, professional services and transaction costs.

Equity in earnings of unconsolidated joint ventures

Equity in earnings of unconsolidated joint ventures was $7.0 million for the six months ended June 30, 2023, compared to equity in earnings of unconsolidated joint ventures of $38.8 million for the six months ended July 1, 2022. This decrease of $31.8 million compared to the six months ended July 1, 2022 was primarily due to a settlement of a claim for a bridge project during the six months ended July 1, 2022 that did not re-occur in the six months ended June 30, 2023.

Gain on sale of property, plant and equipment

Gain on sale of property, plant and equipment was $1.7 million for the six months ended June 30, 2023, compared to $10,000 for the six months ended July 1, 2022, driven by a one-time gain on sale of an office building for $1.7 million.

Other expense, net

Other expense, net was $0.3 million for the six months ended June 30, 2023, compared to $9.6 million in the six months ended July 1, 2022. Other expense, net in the six months ended June 30, 2023 was primarily related to interest expense. Other expense, net in the six months ended July 1, 2022 was primarily driven by changes in fair value of contingent consideration from the AECOM Sale Transactions.

Income tax expense

Income tax expense was $0 in the six months ended June 30, 2023, compared to $1.3 million in the six months ended July 1, 2022. This decrease is due to the company having taxable income as of July 1, 2022, for which utilization of NOL carryforwards is generally limited to 80% of taxable income, with the remaining 20% creating current tax expense. No taxable income is anticipated for 2023, thus no income tax expense was recorded.

Fiscal Year Ended December 30, 2022 Compared to Fiscal Year Ended December 31, 2021

The following table sets forth selected financial data for the fiscal years ended December 30, 2022 and December 31, 2021:

Net income

Net income decreased by $42.9 million to $2.9 million for the fiscal year ended December 30, 2022 compared to $45.8 million for the fiscal year ended December 31, 2021, primarily as a result of the $233.1 million bargain purchase gain recognized in connection with AECOM Sale Transactions in fiscal year 2021, along with an income tax benefit of $24.1 million. The large one-time gains related to the AECOM Sale Transactions were partially offset by higher gross margin of $156.3 million and higher equity in earnings of unconsolidated joint ventures of $51.4 million in fiscal year 2022.

Revenue

Revenue was $664.2 million for the fiscal year ended December 30, 2022 compared to $572.7 million for the fiscal year ended December 31, 2021. Revenue increased by $91.5 million, or 16%, compared to the fiscal year ended December 31, 2021. Revenue increased primarily due to $48 million from two new foundation projects, $19 million from two new dam projects, a $9 million new infrastructure pier upgrade, $11 million in customer directed work at a light rail project, $82 million in ramp up of three projects, and $67 million for a lock replacement which became a loss job in fiscal year 2021. Those increases were partially offset by three projects winding down and nearing completion during fiscal year 2022 reducing revenue by $117 million and one fixed-

63

price project that had increased estimation of total cost at completion (“EAC”) cost during fiscal year 2022 resulting in a $15 million decrease in revenue.

Cost of revenue

Cost of revenues for the fiscal year ended December 30, 2022 decreased by $64.8 million, or 9%, to $640.6 million compared to $705.5 million for the fiscal year ended December 31, 2021. Cost of revenue decreased primarily due to $75 million decrease in the costs on a lock replacement project compared to prior year, which became a loss job resulting from COVID-19 related delays and the impact of higher expenses during fiscal year 2021 and a $121 million decrease in costs on projects winding down or nearing completion in fiscal year 2022 and $31 million of decreases in cost due to higher costs on three jobs in the prior year, partially offset by a $163 million increase in fiscal year 2022, which was primarily due to new projects and ramp up of existing projects.

Selling, general and administrative expenses

Selling, general and administrative expense for the fiscal year ended December 30, 2022 decreased by $17.1 million, or 22%, to $60.4 million compared to $77.5 million for the fiscal year ended December 31, 2021, primarily resulting from higher one-time legal, accounting, professional services and transaction costs in 2021 related to the AECOM Sale Transactions.

Equity in earnings of unconsolidated joint ventures

Equity in earnings of unconsolidated joint ventures was $52.5 million for the fiscal year ended December 30, 2022, compared to equity in earnings of unconsolidated joint ventures of $1.1 million for the fiscal year ended December 31, 2021. Equity in earnings from unconsolidated joint venture arrangements for the fiscal year ended December 30, 2022 increased $51.4 million, compared to the fiscal year ended December 31, 2021, primarily due to a settlement of a claim for a bridge project that had losses in the prior year from increased EAC cost.

Bargain purchase gain

Bargain purchase gain of $233.1 million recorded in fiscal year ended December 31, 2021 was a one-time gain from the AECOM Sale Transactions with no comparable transaction in fiscal year ended December 30, 2022.

Other (expense) income, net

Other expense was $8.7 million for the fiscal year ended December 30, 2022, compared to other income of $0.5 million in fiscal year 2021. Other expenses in fiscal year 2022 primarily related to the changes in fair value of contingent consideration. Other income in fiscal year 2021 was primarily driven by changes in fair value of contingent consideration partially offset by a non-recurring expense that was incurred in connection with the resolution of a dispute.

Income tax (expense) benefit

Income tax expense was $1.3 million in fiscal year ended December 30, 2022, compared to income tax benefit of $24.1 million for the fiscal year ended December 31, 2021. This is primarily due to:

Non-GAAP Financial Measures

We report our financial results in accordance with GAAP. However, management believes that certain non-GAAP financial measures provide investors with additional useful information in evaluating our performance. Therefore, to supplement our condensed consolidated and consolidated financial statements, we provide investors with certain non-GAAP financial measures, including Adjusted net income (loss) and Adjusted EBITDA.

Adjusted Net (Loss) Income

Adjusted net (loss) income represents (loss) income attributable to Shimmick Corporation adjusted to eliminate the bargain purchase gain, changes in fair value of contingent consideration, IPO and transaction-related costs, stock-based compensation, and legal fees and other costs for a legacy project.

We have included Adjusted net (loss) income in this prospectus 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:

Because of these and other limitations, you should consider Adjusted net (loss) income alongside other GAAP- based financial performance measures, including (loss) income attributable to Shimmick Corporation.

Adjusted EBITDA

Adjusted EBITDA represents our earnings before interest and other expense (income), income taxes and depreciation and amortization expense, adjusted to eliminate the bargain purchase gain, changes in fair value of contingent consideration, IPO and transaction-related costs, stock-based compensation, and legal fees and other costs for a legacy project.

We have included Adjusted EBITDA in this prospectus 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.

65

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:

Because of these and other limitations, you should consider Adjusted EBITDA alongside Net (loss) income attributable to Shimmick Corporation, which is the most directly comparable GAAP measure. See reconciliation below:

Liquidity and Capital Resources

Capital Requirements and Sources of Liquidity

During the six months ended June 30, 2023, our capital expenditures were approximately $3.2 million compared to $5.3 million for the six months ended July 1, 2022. During the fiscal years ended December 30, 2022 and December 31, 2021, our capital expenditures were approximately $10.4 million and $2.9 million, respectively. Historically, we have had significant cash requirements in order to organically expand our business to undertake new construction projects. Our cash requirements include costs related to increased expenditures for equipment, facilities and information systems, purchase of materials and production of materials and cash to fund our organic expansion into new markets, including through joint ventures. Our working capital needs are driven by the seasonality and growth of our business, with our cash requirements greater in periods of growth. Additional cash requirements resulting from our growth include the costs of additional personnel, enhancing our information systems and, in the future, our integration of any acquisitions and our compliance with laws and rules applicable to being a public company.

We have historically relied upon cash available through operating activities, in addition to credit facilities and existing cash balances, to finance our working capital requirements and to support our growth. We regularly monitor potential capital sources, including equity and debt financing, in an effort to meet our planned expenditures and liquidity requirements. Our future success will be highly dependent on our ability to access outside sources of capital.

As is customary in the construction business, we are required to provide surety bonds to secure our performance under construction contracts. Our ability to obtain surety bonds primarily depends upon our capitalization, working capital, past performance, management expertise and reputation and certain external factors, including the overall capacity of the surety market. Surety companies consider such factors in relationship to the amount of our backlog and their underwriting standards, which may change from time to time. We have pledged proceeds and other rights under our construction contracts to our bond surety company. Events that affect the insurance and bonding markets may result in bonding becoming more difficult to obtain in the future, or being available only at a significantly greater cost. To date, we have not encountered difficulties or material cost increases in obtaining new surety bonds, and we believe our strong cash position supports our ability to fulfill our surety bond requirements.

We believe that our operating, investing and financing cash flows are sufficient to fund our operations for at least the next twelve months. However, future cash flows are subject to a number of variables, and significant additional expenditures will be required to conduct our operations. There can be no assurance that operations and other capital resources will provide cash in sufficient amounts to maintain planned or future levels of expenditures. In the event we make one or more acquisitions and the amount of capital required is greater than the amount we have available for acquisitions at that time, we could be required to reduce the expected level of expenditures and/or seek additional capital. If we seek additional capital, we may do so through joint ventures, asset sales, offerings of debt or equity securities or other means. We cannot guarantee that this additional capital will be available on acceptable terms or at all. If we are unable to obtain the funds we need, we may not be able to complete acquisitions that may be favorable to us or finance the expenditures necessary to conduct our operations.

Total debt outstanding is presented on the condensed consolidated balance sheets as follows:

67

Loan and Security Agreement

On September 13, 2023, we entered into a Loan and Security Agreement (“Loan Agreement”) with Hudson Bridge Capital, which provides a maximum commitment of $75.0 million and bears interest at an annual rate of 13.0%. Further, the Loan Agreement is subject to a closing fee of 1.50% on proceeds of the Loan. The Loan Agreement matures 36 months from the date of the first draw and repayment of principal does not commence until after the first twelve months of servicing the loan. The Company has not drawn any funds as of September 14, 2023.

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 $30.0 million. The Revolving Credit Facility was subsequently amended on June 30, 2023. As amended, the Revolving Credit Facility provides for a total commitment of $35.3 million and bears interest at an annual rate of adjusted term SOFR, subject to a 1.0% floor, plus 4.50%. 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%. Key financial covenants under the Revolving Credit Facility include maintaining a leverage ratio that does not exceed 1.75 to 1.0 and a minimum cash balance of $25.0 million. The Revolving Credit Facility matures on March 27, 2028. The Company is not aware of any instances of noncompliance with the key financial covenants as of September 14, 2023.

Revolving Line of Credit

We had a $25.0 million Revolving Line of Credit with BMO Harris Bank, N.A., under which the Company had no outstanding borrowings as of June 30, 2023 or December 30, 2022. Borrowings under the Revolving Line of Credit bear interest at a rate based on SOFR or a combination of rates (prime rate, federal fund rate, and SOFR) at the Company’s election, with an added margin depending on the Company’s leverage ratio. The unused balance of the Revolving Line of Credit bears a commitment fee of between 0.25% and 0.40% per year, depending on the Company’s leverage ratio. Key financial covenants under the Revolving Line of Credit include maintaining a leverage ratio that does not exceed 2.0 to 1.0 and a minimum cash balance of $35.0 million. The Revolving Line of Credit terminated on March 27, 2023 upon the Company entering into the Revolving Credit Facility. The Company is not aware of any instances of noncompliance with the key financial covenants as of December 30, 2022.

Cash Flows Analysis

The following table sets forth our cash flows for the periods indicated:

Operating Activities

Our net cash used in operating activities of $60.7 million during six months ended June 30, 2023 was higher than the $18.5 million in net cash used in operating activities during the six months ended July 1, 2022.

68

This change of $42.2 million was due primarily to:

Our net cash used in operating activities of $3.1 million during fiscal year 2022 was comparatively lower than the $54.0 million in net cash used in operating activities during fiscal year 2021.

This change of $50.8 million was due primarily to:

Investing Activities

For the six months ended June 30, 2023, net cash provided by investing activities was $12.6 million, which primarily consisted of cash proceeds from an advance on the sale of non-core business contracts of $20.0 million, proceeds from sale of property, plant and equipment of $4.9 million, and return of investment in unconsolidated joint ventures of $4.3 million, partially offset by unconsolidated joint venture equity contributions of $13.3 million and purchases of property, plant and equipment of $3.2 million. For the six months ended July 1, 2022, net cash provided by investing activities was $14.3 million, which primarily consisted of a net working capital settlement in association with the AECOM Sale Transactions of $32.0 million partially offset by unconsolidated joint venture equity contributions of $13.3 million and purchases of property, plant and equipment of $5.3 million.

For the fiscal year ended December 30, 2022, net cash provided by investing activities was $4.2 million which primarily consisted of proceeds from the net working capital settlement in association with the AECOM Sale Transactions of $32.0 million, partially offset by purchases of property, plant and equipment of $10.4 million and

69

unconsolidated joint venture equity contributions of $19.7 million. For the fiscal year ended December 31, 2021, net cash provided by investing activities was $136.2 million, which primarily consisted of cash acquired in the AECOM Sale Transactions of $160.4 million, partially offset by unconsolidated joint venture equity contributions of $23.0 million.

Financing Activities

For the six months ended June 30, 2023, net cash provided by financing activities was $29.0 million, which primarily consisted of proceeds from the Revolving Credit Facility borrowings of $30.0 million. For the six months ended July 1, 2022, net cash used in financing activities was $0.2 million, which consisted solely of payments on our finance lease obligation.

For the fiscal year ended December 30, 2022, net cash used in financing activities was $0.9 million, which consisted of payments on our finance lease obligation of $0.3 million and distributions to non-controlling interests of $0.7 million. For the fiscal year ended December 31, 2021, net cash used in financing activities was $0.3 million, which consisted solely of payments on our finance lease obligation.

Letters of Credit

We obtain standby letters of credit required by our insurance carriers. As of June 30, 2023, December 30, 2022 and December 31, 2021, the total amount of standby letters of credit outstanding were $ 14.1 million, $8.2 million and $5.0 million, respectively.

Contractual Obligations

Contractual obligations of the Company consisted of liabilities associated with remaining lease payments for the six months ending December 29, 2023 through the fiscal years ending through December 31, 2027 of approximately $6.2 million, $9.6 million, $7.6 million, $3.1 million and $1.8 million, respectively, and approximately $2.5 million in the aggregate thereafter based on balances outstanding as of June 30, 2023.

Off-Balance Sheet Arrangements

In our joint ventures, the liability of each partner is usually joint and several. This means that 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. We are unable to estimate the maximum potential amount of future payments that we 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 our joint venture partners, resource availability, potential performance delays caused by the defaults, the location of the projects, and the terms of the related contracts.

70

Critical Accounting Estimates

The discussion of our financial condition and results of operations is based upon our condensed consolidated and consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We evaluate our estimates and assumptions on an ongoing basis. The results of our analysis form the basis for making assumptions about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions, and the impact of such differences may be material to our condensed consolidated and consolidated financial statements.

Revenue Recognition

The Company recognizes revenue from signed contracts with customers, change orders (approved and unapproved) and claims on those contracts that we conclude to be enforceable under the terms of the signed contracts. Many of the Company’s contracts have one clearly identifiable performance obligation. However, some contracts provide the customer an integrated service that includes two or more of services associated with construction, operations and management. The determination of the number of performance obligations in a contract requires significant judgment and could change the timing of the amount of revenue recorded for a given period.

Determination of the contract price is dependent upon a number of factors, including the accuracy of a variety of estimates made at the balance sheet date, such as estimated costs at completion. Additionally, the Company is required to make estimates for the amount of consideration to be received, including variable compensation such as bonuses, awards, incentive fees, claims, unapproved change orders, unpriced change orders, penalties, and liquidated damages. The Company’s estimates of variable consideration and determination of whether to include such amounts in the contract price are based largely on the Company’s assessment of legal enforceability, anticipated performance, and any other information (historical and forecasted) that is reasonably available to the Company. Management continuously monitors factors that may affect the quality of its estimates, and makes adjustments accordingly.

The Company has numerous contracts that are in various stages of completion which require estimates to determine the forecasted costs at completion. Due to the nature of the work left to be performed on many of the Company’s contracts, the EAC for fixed-price contracts is complex, subject to many variables and requires significant judgment. Estimates of total cost at completion are made each period and changes in these estimates are accounted for prospectively as cumulative adjustments to revenue recognized in the current period. If estimates of costs to complete fixed-price contracts indicate a loss, a provision is made through a contract write-down for the total loss anticipated in cost of revenue.

Change Orders

Contracts are often modified to account for changes in contract specifications and requirements. Most of the Company’s contract modifications are for goods or services that are not distinct from existing contracts due to the significant integration provided in the context of the contract and are accounted for as if they were part of the original contract. The effect of a contract modification on the transaction price and the Company’s measure of progress for the performance obligation to which it relates are recognized as an adjustment to revenue (either as an increase or decrease) on a cumulative catch-up basis.

Claims Recognition

Sometimes the Company seeks claims for amounts in excess of the contract price for delays, errors in specifications and designs, contract terminations, change orders in dispute or other causes of additional costs incurred. Costs attributable to claims from customers are treated as costs of contract performance as incurred. The transaction price does not include any amounts collected on behalf of third parties, such as sales tax.

71

Income Taxes

The Company accounts for income taxes under the asset and liability method prescribed by the Accounting Standards Codification Topic 740 — Income Taxes (“ASC 740”). This method requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the condensed consolidated and consolidated financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the condensed consolidated and consolidated financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse.

The Company recognizes deferred tax assets to the extent that its management believes these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, it will make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

Emerging Growth Company and Smaller Reporting Company

We are an “emerging growth company,” as defined in the JOBS Act. For so long as we are an emerging growth company, we will, among other things:

In addition, Section 107 of the JOBS Act provides that an emerging growth company can use the extended transition period provided in Section 7(a)(2)(B) of the Securities Act, for complying with new or revised accounting standards. This permits an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

We are also a smaller reporting company as defined in the Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as our voting and non-voting common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter, or our annual revenue is less than

$100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter. See “Risk Factors — General Risk Factors — We are on emerging growth company and because we take advantage of specified reduced disclosure requirements applicable to emerging growth companies and smaller reporting companies, our financial statements may not be comparable to companies that comply with public company effective dates, which may make our common stock less attractive to investors.”

Internal Controls and Procedures

As an emerging growth company and smaller reporting company, we are not currently required to maintain an effective system of internal controls as defined by Section 404(b) of the Sarbanes-Oxley Act. We will be required to comply with the internal control requirements as defined by Section 404(a) of the Sarbanes-Oxley Act for the fiscal year ending December 29, 2023. Only in the event that we are deemed to be a large accelerated filer or an accelerated filer, and no longer qualify as an emerging growth company and smaller reporting company, would we be required to comply with the independent registered public accounting firm attestation requirement on the effectiveness of our system of internal control over financial reporting. Further, for as long as we remain an emerging growth company as defined in the JOBS Act, we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies or smaller reporting company including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirement on the effectiveness of our system of internal control over financial reporting. See “Risk Factors — General Risk Factors — If, after this offering, we are unable to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act as it applies to an emerging growth company that is listed on an exchange for the first time, or if we are unable to maintain effective internal controls over financial reporting, investors may lose confidence in the accuracy of our financial statements and our share price may suffer.”

In the course of preparing the condensed consolidated and consolidated financial statements that are included in this prospectus, our management has determined that we have material weaknesses in our internal control over financial reporting, which relate to the lack of a sufficient number of trained resources with assigned responsibilities and accountability for the design and operation of internal controls over financial reporting, lack of formal and effective controls over certain financial statement account balances, and lack of formal and effective controls over the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) principles including control environment, risk assessment, control activities, information and communications and monitoring which resulted in material adjustments in the preparation of our condensed consolidated financial statements as of and for the six months ended June 30, 2023 and July 1, 2022 and consolidated financial statements as of and for the fiscal years ended December 30, 2022 and December 31, 2021.

In order to remediate these material weaknesses, we have hired and continue to seek out additional accounting and finance staff members with public company reporting experience to augment our current staff and to improve the effectiveness of our closing and financial reporting processes and are currently implementing key controls over financial reporting and COSO principles. While we have implemented a plan to remediate these material weaknesses, the steps we have taken to date, and that we are continuing to implement, may not be sufficient to remediate these material weaknesses or to avoid the identification of other material weaknesses in the future.

Notwithstanding the material weaknesses that existed at June 30, 2023 and December 30, 2022, our management has concluded that the condensed consolidated financial statements included elsewhere in this prospectus present fairly, in all material respects, our financial position, results of operations and cash flows in conformity with GAAP.

If we fail to fully remediate these material weaknesses or fail to maintain effective internal controls in the future, it could result in a material misstatement of our condensed consolidated and consolidated financial statements that would not be prevented or detected on a timely basis, which could cause investors to lose confidence in our

73

financial information or cause our stock price to decline. Our independent registered public accounting firm has not assessed the effectiveness of our internal control over financial reporting and, under the JOBS Act, will not be required to provide an attestation report on the effectiveness of our internal control over financial reporting so long as we qualify as an emerging growth company, which may increase the risk that material weaknesses or significant deficiencies in our internal control over financial reporting go undetected.

Quantitative and Qualitative Disclosures about Market Risk

BUSINESS

Our Company

We are a leading provider of water and other critical infrastructure solutions nationwide. Through our predecessor entities, we have a long history of working on complex water projects, ranging from the world’s largest wastewater recycling and purification system in California to the iconic Hoover Dam. According to Engineering News Record, in 2022 we were nationally ranked as a top ten builder of dams and reservoirs (#1), water supply (#3), water treatment and desalination plants (#8) and mass transit (#9). We are led by industry veterans, many with over 20 years of experience, and work closely with our customers to deliver complete solutions, including long-term operations and maintenance.

The United Nations has stated that climate change is primarily a water crisis as water becomes more scarce, unpredictable, polluted, or a combination of all three. Climate change, along with other emerging issues like drinking water contamination, requires significant and complex solutions like those we provide. We believe we are entering a period of substantial investment in water solutions, with more than $60 billion already authorized by federal legislation. In addition to organic growth opportunities, the existing water industry is highly fragmented by geography and capability, and we believe there is significant opportunity to both further expand our core infrastructure services and provide new services through acquisitions.

We selectively focus on the following types of infrastructure projects:

We were founded in 1990 in California. In 2017, AECOM acquired Shimmick and consolidated us with its existing construction services, which included former legacy construction operations from Morrison Knudsen, Washington Group International, and others. In January 2021, we began operating as an independent company under new private ownership. While our legacy companies have a long history operating in the United States, we have a limited operating history as an independent company. Following our separation from AECOM, we began a transformation to shift our strategy to meet the nation’s growing need for water and other critical infrastructure. We believe our competitive strengths, which are discussed below, position us to execute this strategy and capitalize on market opportunities. However, our limited operating history as an independent company and historical dependence on AECOM subject us to a number of risks, such as an inability to obtain necessary bonding and the need to incur additional operating expenses to create or supplement the corporate infrastructure necessary to operate as an independent company. We are also involved in ongoing disputes with AECOM,

75

which could adversely impact our business. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — AECOM Sale Transactions” for a definition and discussion of the AECOM Sale Transactions and “Risk Factors — Risks Related to our Projects — We have a limited operating history as an independent company and have been historically dependent on our prior owner, AECOM,” “— Risks Related to Our Business and Industry — We are involved in ongoing disputes with our prior owner, AECOM, which could adversely impact our business,” “— We may be required to make additional payments to AECOM pursuant to contractual arrangements” and “— If AECOM defaults on its contractual obligations to us or under agreements in which we are a beneficiary, our business could be materially and adversely impacted” for a discussion of risks related to AECOM.

For the six months ended June 30, 2023 and July 1, 2022, we generated revenue of $319.3 million and $293.6 million, respectively, and net (loss) income attributable to Shimmick Corporation of $(19.6) million and $3.7 million, respectively. Adjusted EBITDA was $(2.9) million and $31.9 million for the six months ended June 30, 2023 and July 1, 2022, respectively. Adjusted net (loss) income was $(12.0) million and $22.7 million for the six months ended June 30, 2023 and July 1, 2022, respectively. For the years ended December 30, 2022 and December 31, 2021, we generated revenue of $664.2 million and $572.7 million, respectively, and net income attributable to Shimmick Corporation of $3.8 million and $45.4 million, respectively. Adjusted EBITDA was $47.0 million and $(193.6) million for the years ended December 30, 2022 and December 31, 2021, respectively. Adjusted net income (loss) was $29.5 million and ($184.3) million for the years ended December 30, 2022 and December 31, 2021, respectively. For reconciliations of Adjusted EBITDA and Adjusted net (loss) income to net (loss) income, the most directly comparable GAAP financial measure, see “Prospectus Summary — Summary Selected Consolidated Financial Data.”

As of June 30, 2023, we had a backlog of projects in excess of $1 billion, with over half of that amount comprised of water projects. We believe we have the ability to self-perform many of these projects, enabling us to compete for complex projects and differentiating us from many of our competitors. Self-performance also enables us to better control the critical aspects of our projects, reducing the risk of cost and schedule overruns.

Our Customers

Our project revenue and contracts come primarily from public customers such as federal, state, and local governments, including water districts, sanitation districts, irrigation districts, and flood control districts. Government backing provides financial stability and reliability, as public projects are funded by government entities with the authority to collect taxes and allocate funds. Diverse funding sources — grants, appropriations, loans, state and local taxes, and user fees — reduce dependence on a single source and enhance overall market stability.

Throughout our history, we have maintained and cultivated a strong presence in California. In 2022, more than half of our revenue was generated in California, the largest construction market in the United States. The amount of construction put in place for water infrastructure in California was $4.9 billion in 2022, according to S&P. Our revenue from water projects in California was less than 10% of the total California water market, indicating ample opportunity for us to grow our market share in California, where we believe we possess significant competitive advantages.

For example, we have detailed knowledge of the California market and have developed long-standing relationships with significant customers, including the OCSD, the OCWD, the MWD, the Port of Long Beach, the Port of Los Angeles, the City of San Francisco, the City and County of Los Angeles, and other public agencies across the state. In addition to long-standing relationships with our customers, our decades of industry experience have supplied us with deep knowledge of the local workforce, subcontractors, and suppliers throughout the state, which we believe provides us with a distinct pricing advantage and enables us to better manage risk.

We also have a long history of delivering solutions for the federal government, primarily building locks, dams, levees, and flood protection along the nation’s inland waterways and coasts. Our federal clients include the Navy and numerous USACE districts, including the Louisville District in Kentucky, the Rock Island District in Illinois, and the Nashville District in Tennessee. This work supports efficient transportation, which helps boost trade, reduce congestion on roads, and enhance our nation’s economy.

Our Growth Strategy

Following consummation of the AECOM Sale Transactions, we began a transformation to shift our strategy to meet the nation’s growing need for water and other critical infrastructure and grow our business. We are beginning to see the benefits of that transition. Projects that were secured prior to the AECOM Sale Transactions, including large scale projects with higher risk and lower margins, is being worked off and replaced with smaller and mid-sized projects with less risk and higher margins. As a result of our renewed strategic focus on water infrastructure, for the first time in company history, in September 2022, Shimmick was ranked in the top ten for dams and reservoirs, water supply, and water treatment and desalination by Engineering News Record.

Our growth strategies are as follows:

Organically Grow Core Water and Critical Infrastructure Business. We seek to further expand our market share in water and other critical infrastructure to meet the nation’s needs for clean water, economic development, disaster mitigation, trade, and resilience. We anticipate a prolonged and growing demand for the markets we currently serve, due to, among other things, growing coastal populations, climate change, drought and severe weather events, and increased activity along the inland waterways, where, according to the most recent ASCE Report Card for Inland Waterways nearly 830 million tons of the nation’s goods are transported every year. Accordingly, we aim to increase the share of water projects as a percentage of our overall backlog. We plan to continue focusing on building infrastructure that meets our customer’s needs — like water reuse, recycling, and conservation — and capitalize on significant opportunities within our core market of California.

We believe that by carefully positioning ourselves in markets that have meaningful barriers to entry, as discussed below, we can realize meaningful advantages. For example, we target projects requiring highly technical or specialized scopes of work or in our core market of California, where we can leverage our deep knowledge of and relationships with customers, workforces, subcontractors, and suppliers. We believe this provides us with a distinct pricing advantage, as well as better risk management.

Enhance Profitability. With a consistent focus on profitability by our management team and growing demand for critical infrastructure, we believe we can further enhance margins through disciplined project selection and bidding. We believe that the need and funding for projects may exceed the industry’s capacity, enabling us to opportunistically target smaller specialized projects with less risk at higher margins.

We maintain a disciplined project evaluation process during which we look at a wide range of factors when determining which projects to bid. Certain criteria are considered at each stage of the pursuit process, which may include project size, location, customer, scope of work, availability of resources, anticipated competition, and project duration, among others. We selectively bid on projects that we believe offer an opportunity to meet our profitability objectives or that offer the opportunity to strategically grow our market share. In addition, we review our bidding opportunities to attempt to minimize concentration of work with any one customer or in tight labor markets.

We also believe that complex projects require companies like ours to have specific technical experience, the ability to obtain surety bonds, a trained workforce, geographic presence in key markets, and specialty equipment. These requirements, among others, present certain barriers to entry, which limits competition and enables us to maintain selectivity and a desired level of profitability. Additionally, we believe the demand for services like ours is outpacing the industry’s ability to supply those services. As illustrated by a few of our recent bids, we were one of just three bidders on the Folsom Dam for USACE, one of two bidders for Control Upgrades at Plant No. 2 for the Orange County Sanitation District, and the sole bidder on the Regional Water Reclamation Facility for the Elsinore Valley Municipal Water District.

Expand Service Offerings for Water and Critical Infrastructure Through Strategic Acquisitions. Upon completion of this offering, we intend to complement our organic growth through strategic acquisitions. We will opportunistically evaluate strategic acquisitions that would enable us to pursue complementary markets or enter

77

new geographies where we do not have an existing footprint. Specifically, we plan to target companies that expand our existing solutions to provide additional capabilities along the water value chain, such as solutions for influent and effluent water conveyance, physical, chemical and/or biological water treatment, water testing, commissioning and operations and maintenance or other services which provide additional recurring revenue opportunities. Our industry includes a number of companies whose growth potential we believe has plateaued absent additional capital infusion or that otherwise may be seeking a liquidity event, which we believe presents opportunities for us to further our growth through strategic acquisitions. We believe the proceeds from this offering, along with existing cash on hand, publicly traded stock and access to capital markets, will enable us to leverage our established platform and the acquisition experience of our management team positions us well to capitalize on future acquisition opportunities and accelerate our growth.

Our Competitive Strengths

With decades of industry experience and a track record of delivering water and other critical infrastructure projects, we believe we are well-positioned to address market trends and meet the growing needs of our current and prospective customers. We believe our long-standing customer relationships, revenue stability, market-leading positions in key markets, effective risk management, presence in key geographies, and a commitment to talent development further contribute to our future success.

Track Record of Water and Other Critical Infrastructure. Through our decades of experience, we have developed efficient processes and controls that allow us to successfully deliver critical infrastructure projects. Our strategy shift to focus on water treatment facilities, dams, locks, and levees, coupled with recent and strong underlying market dynamics, has helped us become a market leader.

Self-Performance of Contracts. We believe we are differentiated from our competitors by our ability to self-perform virtually all aspects of the critical infrastructure projects we build. We believe our ability to self-perform these project scopes makes us more competitive, as we are able to confidently estimate the cost of each job package given our expertise, track record, and expectation that we will self-perform up to 80% of the elements in a typical construction contract. Self-performance offers numerous benefits, both internally and for our customers, including: better cost and quality control, greater control over work sequencing to reduce potential delays, increased flexibility and responsiveness, and a single point of accountability for our customers, all of which simplify project management. Self-performance also creates additional value by enabling us to capture profit margin that would typically be shared with subcontractors.

Customer and Revenue Stability. In 2022, the vast majority of our revenue was derived from public projects. Our public customers include water districts, sanitation districts, irrigation districts, flood control districts, USACE, cities, counties, and others. Government backing provides financial stability and reliability, since public projects are funded by government entities with the authority to collect taxes and allocate funds. Long-term planning and public interest behind infrastructure projects help ensure consistent funding allocation. Governments also have legal obligations to provide and maintain essential infrastructure, further solidifying the stability of public funding. Diverse funding sources — grants, appropriations, loans, state and local taxes, and user fees — reduce dependence on a single source and enhance overall market stability. Additionally, countercyclical investment, like federal stimulus during economic downturns, contributes to the stability of public funding. We believe this strategy enables us to better manage our business through market cycles.

Framework for Managing Construction Projects and Contract Risk. Our long history in these markets provides us with an understanding of the various risks of infrastructure construction. Following the AECOM Sale Transactions, we enhanced our monitoring and risk management practices applied throughout the entire project lifecycle, including the bid process, pre-construction planning activities, and construction. Our senior management reviews all bid proposals prior to submission, thereby increasing accountability and an understanding of the financial and operating risks and opportunities of our contracts. We maintain a database of prior contract proposals and records from completed projects, such as raw material requirements and costs, labor

78

requirements and costs, and equipment needs, enabling us to rely on our institutional knowledge when estimating project costs in developing new proposals.

Long-Term Relationships with Customers and Partners. Over the past 30 years, we have developed strong relationships with major infrastructure owners including the OCWD, the City of San Diego, Bay Area Rapid Transit, the Ports of Long Beach and Los Angeles, the City of San Francisco and the City and County of Los Angeles. Elsewhere, we have delivered work for numerous USACE districts, including Louisville, Kentucky, Rock Island, Illinois, Omaha, Nebraska, and Nashville, Tennessee. In fact, most of our revenue in 2022 was generated from repeat customers, leveraging established relationships, familiarity with expectations, and enhanced collaboration for improved outcomes.

Strong Culture and Values with a Commitment to Talent Development. We seek to foster a culture of professional development for each employee. We focus on hiring and retaining highly talented employees with diverse backgrounds and empowering them to create value for our stockholders. We believe our success is dependent on employee understanding of and investment in their role in that value creation. We recruit many of our new employees from a network of approximately two dozen college campuses, where we seek to identify diverse candidates with a desire to develop as construction and engineering professionals and who have key intangible qualities in addition to academic credentials. We believe that our culture, combined with the opportunity to work on complex projects, provides unique opportunities for our employees to grow within our organization. We also encourage our employees to take proactive steps to advance their development and we support our employees in achieving the Professional Engineer designation. Our commitment to career and leadership development is evidenced in our core values, which include Safety, Achievement, Transparency, Empowerment and Responsibility, Authentic Relationships and Mutual Trust and Support. As a guiding principle, we are committed to supporting our employees as they develop their careers.

Experienced Executive Team with Significant Equity Incentive. Many members of our senior leadership team have over 20 years of industry experience and have worked together for over a decade. Additionally, as of June 30, 2023, members of our management team currently held vested and unvested stock options representing over 15% of our common stock on a fully-diluted basis (or  % after giving effect to this offering), which will significantly align their interests with stockholders.

Our Projects

We have historically pursued publicly funded water and other critical infrastructure projects. These projects include water and wastewater treatment, water conveyance (pipes, pump stations, irrigation and drainage channels), water storage (dams, reservoirs, weirs), flood protection (levees, flood walls), and environmental projects (species protection, fish ladders, hatcheries), as well as other critical infrastructure. These projects enhance connectivity, trade and economic growth.

As noted above, we have the ability to self-perform virtually all aspects of the critical infrastructure projects we build. However, at times, we may enter into joint venture arrangements on certain projects where it is necessary or desirable to share expertise, risk and resources. Joint venture partners typically provide independently prepared estimates, shared equipment, and often bring local knowledge and expertise. The services we self-perform versus those we rely upon subcontractors and joint venture partners to perform vary from project to project. Our decision regarding whether to self-perform work required depends on multiple factors, including location, availability of subcontractors, availability of craft, size of project, risk management objectives, scope and cost of self-performing versus subcontracting. For example, we joined with a joint venture partner on one of our current projects for their expertise on structural steel related specifically to retrofitting tainter gates. As of June 30, 2023, we had a backlog of projects of $1.3 billion, approximately $142 million, or 11%, of which are through our joint venture arrangements.

Water Treatment

Our experience in the water treatment space includes a wide range of treatment technologies. For example, for Orange County’s Groundwater Replenishment System Expansion, we delivered a three-step advanced process

79

consisting of microfiltration, reverse osmosis and ultraviolet light with hydrogen peroxide to produce water that meets and exceeds state and federal drinking water standards. The new 30 MGD expansion, completed in 2023, created an additional 31,000 acre-feet per year of new water supply and expanded the facility’s capacity to provide water for one million people.

Desalination, another treatment process, removes salt and other impurities from seawater or brackish water to produce freshwater and provides a reliable and alternative source of freshwater in regions facing water scarcity. Desalination also supports economic development and population growth in arid coastal areas. Although desalination plants come with unique environmental and regulatory challenges, desalination remains an important part of a larger, multi-billion dollar strategy to address drought and water scarcity in California, according to the California Water Board Water Supply strategy, published in August 2022. For example, in 2020 the California Department of Water Resources awarded over $82 million in Proposition 1 desalination grants to support 20 projects. One of the projects that has received Proposition 1 funding is the Antioch Desalination Plant. To combat the increase in water salinity, Shimmick is adding a desalination reverse osmosis treatment train to this existing plant in Antioch. This work will enable the plant to continue to provide a drought-resistant water supply, reduce reliance on imported water, enhance water reliability, support agricultural needs, and contribute to the overall water security and sustainability in the San Joaquin Delta System and surrounding areas. Also, in 2018, we expanded the Robert W. Goldsworthy Desalter facility in Los Angeles County. Using reverse osmosis, the facility processes salty, brackish groundwater to create fresh, potable water. We also improved the facility’s reverse osmosis capabilities, installing new filter membranes and analysis and monitoring instrumentation.

Water Resources

According to Engineering News Record, we were the nation’s largest builder of dams and reservoirs and third largest builder of water supply systems in 2022. These critical infrastructure projects control flooding, store and supply water, and improve water quality to meet public demands. We also improve locks along the nation’s inland waterways, enabling the efficient and emissions-reducing transportation of goods, supporting commerce, and connecting regions for economic growth and trade.

At the LaGrange Lock and Dam in Illinois, USACE chose us to perform a major rehabilitation of the more than 80-year-old dam along one of the main inland waterways where barges transport nearly 830 million tons of the nation’s goods every year, according to the most recent ASCE Report Card for Inland Waterways. Additionally, we recently completed the Rapid Disaster Infrastructure program, building more than five miles of levees in Missouri to protect the area from flooding. A Shimmick-led joint venture also replaced an aging lock and dam and constructed the new Olmsted Dam on the Ohio River, where according to USACE, more commerce traverses than any other location on the entire U.S. inland waterways. With the Olmsted lock and dam replacement, economic net benefits to the nation are estimated to be more than $640 million annually, according to the same ASCE Report Card.

In California, as part of a joint venture, we recently secured a project for USACE to raise the main dam in Folsom. The project, set for completion in 2027, will enhance flood control by increasing temporary storage capacity of the reservoir by 43,000 acre-feet, reducing flood risk in the greater Sacramento area.

Other Critical Infrastructure

Critical infrastructure refers to the systems, assets, and facilities that are essential for the functioning and well-being of our nation. They are vital for maintaining national security, public health and safety, and economic stability. Disruptions or failures in critical infrastructure can have significant consequences and impact the functioning of society.

Our most recent example of critical infrastructure delivered for the military was the Point Loma Navy Fuel Pier Replacement. This project was necessary to ensure the safe and efficient refueling of naval ships and to meet current operational and safety standards. We demolished and removed the existing pier, installed a new fueling pier, and performed other security improvements to enhance the Navy’s ability to maintain its fleet of surface ships, submarines, and other vessels.

We have included project details below for projects currently in progress or recently completed. These projects represent a typical cross-section of the common types of projects we deliver in terms of scope, customer type, and geography.

81

Our Market Opportunity

Due to water’s essential nature, climate change, coastal population growth, aging infrastructure, regulatory requirements, infrastructure resilience needs, and technological advancements, we anticipate the demand for

82

water infrastructure to continue to grow. Aging infrastructure requires maintenance and upgrades, while regulatory standards, as well as new extreme weather patterns like droughts, drive the need for conveyance, new facilities and treatment technologies. Additionally, water infrastructure is critical and, in many cases, life-sustaining, less impacted by economic downturns than other markets like residential or commercial construction. We believe these and other factors contribute to the sustained demand for water infrastructure, for which we have already seen a significant increase in authorized spending.

The Infrastructure Investment and Jobs Act (“IIJA”), passed in November 2021, authorized the spending of $1.2 trillion over five years to expand access to clean drinking water, rebuild the nation’s transportation system, and address climate change, among other initiatives. Of the $1.2 trillion in supplemental spending authorized by the IIJA, more than $50 billion will go to the EPA to strengthen the nation’s drinking water and wastewater systems, representing the single largest investment in water ever by the federal government and representing a significant, multi-year market opportunity for Shimmick. Specifically, it provides more than $20 billion for safe drinking water, with $12 billion going to a state clean water revolving fund, to which states can apply for grants and loans for critical water infrastructure projects. The remainder, around $9 billion, will address emerging contaminants, including PFAS in drinking water. Another $15 billion is included to replace lead pipes, more than $12 billion to ensure clean water for communities, and nearly $2 billion for regional water protection.

According to S&P, water and other critical infrastructure spending is forecasted to have a compound annual growth rate (“CAGR”) of 5% between 2023 and 2027. Additionally, because projects often take several years to plan and advertise, we believe the bulk of the newly authorized spending is yet to come. According to Dodge Data’s 2023 second quarter forecast, just 35% of the IIJA funding has flowed to projects thus far, with the bulk of spending coming in future years. Despite economic uncertainty surrounding federal monetary policy and inflationary pressures, nonbuilding infrastructure starts, defined by Dodge Data as public works like dams, sewerage and waste disposal, water supply, and bridges, are forecasted to see a 16% increase to $281 billion in 2023. Furthermore, nonbuilding infrastructure will be “more insulated from economic turmoil than other sectors” due to the recent passage of several federal legislative efforts, according to Dodge Construction Network’s 2023 Construction Outlook.

In addition to the IIJA, the American Rescue Plan Act of 2021 provided another $6.5 billion in grants for state and local governments for water projects through 2024. Although the bill was originally designed to address impacts related to the COVID-19 pandemic, the final version provides state and local governments with “wide latitude to identify investments in water and sewer infrastructure that are of the highest priority for their own communities.” By permitting funds to be used for water and sewer infrastructure needs, the revised rule states that, “Congress recognized the critical role that clean drinking water and services for the collection and treatment of wastewater and stormwater play in protecting public health.”

Management considers the size of our market opportunity to be the total market opportunity for all companies similarly situated to meet the demand for water infrastructure, which includes our current competitors and any future market entrants. We estimate that the total market opportunity for water infrastructure is $60 billion, and given current competitors and future market entrants, we will likely only be able to convert on a portion of that market opportunity. Furthermore, the federal government and our private clients may face challenges implementing the funding allocated to them, which would decrease the size of the total estimated market opportunity.

California

One of California’s major economic drivers is water availability. Seventy-five percent of California’s water supply comes from watersheds north of Sacramento, while the state’s highest demand comes from the south. This requires an extensive network of water conveyance, storage, and other infrastructure to deliver water where it is most needed. As the most populous state in the U.S., California delivers drinking water to around 40 million people through a robust network of water facilities. California maintained more than 420 wastewater treatment plants and processed more than five million acre-feet, or nearly two trillion gallons, of influent and effluent water in 2021.

83

California’s water infrastructure has deteriorated over the last several decades. The EPA 2018 Drinking Water Infrastructure Needs Survey and Assessment determined that the cost of California’s water infrastructure needs to be increased to over $51.0 billion. California’s needs include an estimated $31.6 billion to improve drinking water transmission, $9.2 billion for water treatment and $7.0 billion for water storage. According to S&P, the size of the California water and transportation infrastructure market, the largest market in which we operate, will be approximately $23 billion in 2024. It is projected to grow nearly 30% faster than the national average, with a nominal CAGR of approximately 7% between 2023 and 2027.

In 2017, the Public Policy Institute of California (“PPIC”) reported that “every county has been declared a flood disaster area multiple times.” And that “transportation, energy, water supply, and sewer networks are also at risk of disruption.” Due to these factors, proactive steps are being taken to fund water projects and programs. According to the PPIC, Californians have approved $27.0 billion in water bonds since 2020.

Additionally, California is the federal government’s largest recipient of formula-based funds for infrastructure, with $39.0 billion expected from the IIJA over the next five years and another $3.5 billion in federal funding for clean water infrastructure. In November 2022, California received $609 million in supplemental state revolving funds from the EPA for water projects, by far the most allocated to any state.

Since the passage of the California Infrastructure Planning Act in 1999, the California Governor’s office has been required to submit a five-year infrastructure plan with the annual budget bill to the California Legislature for consideration. California enacted a 2023-2024 total budget of $310 billion, which allocates more than $32 billion for infrastructure.

Additionally, the federal Bipartisan Budget Act of 2018 allocated $3.5 billion to improve water infrastructure in California and $8 billion for western water infrastructure. The Inflation Reduction Act provides another $4 billion for drought relief throughout western states, including California. According to the PPIC, over the past three years the California state legislature has authorized more than $8 billion to improve water supply and river and wetland ecosystems.

Funding for water-related projects also comes from revenue generated from water sales. In California, the vast majority (84%) of water projects are funded from local water bills and taxes. The balance comes from state (13%) and federal (3%) contributions.

Federal

According to an April 2023 Congressional Resource Service report, the IIJA provided $17.1 billion in direct, emergency appropriations to USACE for construction (68%), operations and maintenance (23%) and Mississippi River and Tributaries (5%). Much of this funding is being allocated directly to the core markets in which we operate, including $2.5 billion to inland waterways and another $5 billion for coastal and inland flood management. The remainder is slated for aquatic ecosystem restoration, pilot programs for flood risk, and other programs.

In addition to the IIJA, the Bipartisan Budget Act, passed in 2018, authorized $15 billion for construction for projects like the Sabine Pass to Galveston Bay Coastal Storm Risk Management Program that will reduce risk from coastal storm surges along the Texas coast. Shimmick is currently pursuing this important project, and if prequalified, will be granted the opportunity to bid task orders under the $7 billion MATOC. The USACE has already prequalified Shimmick for two other MATOCs this year — the Huntington Land Based Construction MATOC and the Nashville Construction MATOC. Shimmick is one of two large businesses prequalified on Huntington MATOC and one of four large businesses prequalified for Nashville MATOC. MATOCs limit competition to a subset of prequalified competitors and offer significant, long-term project and revenue opportunities.

Both the IIJA and the Bipartisan Budget Act are supplemental to the USACE’s annual budget, which in recent years has been approximately seven to eight billion dollars annually, historically reflecting modest year-over-year increases. This funding is directly appropriated to USACE for projects outlined in its annual work plans.

Our Industry

Several long-term trends, including the impact of climate change, the deterioration of aging infrastructure, and coastal population growth, have resulted in a renewed focus on infrastructure development and funding in the United States. Droughts and flooding in the west, along with extreme weather along coastal states, have demonstrated the need for expanded water and storm water infrastructure, flooding mitigation and disaster recovery efforts. In addition, our nation’s infrastructure, much of it built more than 50 years ago, has deteriorated over the last several decades.

The demand for water infrastructure stems from multiple factors driving the need for reliable water management systems. Growing urbanization and industrialization have amplified water consumption, putting pressure on existing water supply networks. Furthermore, aging infrastructure in many regions requires significant upgrades and modernization to ensure clean water delivery, effective flood control, and efficient navigation.

Critical infrastructure ensures the efficient movement of goods and people, supports economic growth, and enhances connectivity between regions. Major economic drivers for these projects include increasing international trade, urbanization, and population growth. As governments and private entities continue to invest in upgrading and expanding infrastructure to meet these demands, opportunities for innovative solutions and technologies are expected to flourish.

Based on these and other factors, we believe that demand for construction and ongoing maintenance of water and other critical infrastructure projects will continue to increase.

Water Treatment

In the United States, the delivery of drinking water, wastewater treatment, and stormwater services rely on a comprehensive network of treatment plants, pumps, pipes, storage facilities, and other essential components. According to an ASCE Report, more than 50,000 drinking water systems distribute 39 billion gallons of drinking water to U.S. homes, industries, and other businesses. These systems are regulated by the EPA and state agencies under the Safe Drinking Water Act. The drinking water systems in the United States have been assessed as poor/at-risk, with a grade of C- by the ASCE.

With over 16,000 publicly owned wastewater treatment systems, centralized plants are expected to handle a larger share of wastewater treatment due to urban growth. These systems are currently operating at an average of 81% of their design capacity, with 15% exceeding capacity. Many systems built in the 1970s under the Clean Water Act are reaching the end of their expected 40- to 50-year lifespan. Nationwide, water pipes average 45 years old, and some components are over a century old, despite an expected lifespan of 50 to 100 years.

Water Resources

According to the America’s ASCE Infrastructure Report Card, there are over 91,000 dams with an average age of 57 years across the U.S. Approximately 15,600 dams in the United States are classified as high-hazard structures, with an estimated rehabilitation cost for non-federal dams of nearly $20 billion.

The inland waterway network in the United States is comprised of approximately 12,000 miles of inland navigation channels as well as an additional 11,000 miles of intracoastal waterways owned and operated by the USACE. Most of the locks and dams are well past their 50-year design life. According to the ASCE’s 2021 America’s Infrastructure Report Card, the USACE backlog of authorized projects that are waiting for appropriations funding, which includes the nation’s inland waterway locks and dams, is $6.8 billion. The ASCE reports a navigation backlog of $2.7 billion annually in unmet maintenance work activities. Estimates show the need to rehabilitate federal dams is approximately $27.6 billion.

Industry Drivers and Trends

We believe our core markets of water and other critical infrastructure are in the midst of a prolonged expansion, driven by several macro-economic and geopolitical trends, including the following:

Climate change and extreme weather events. The U.N. Intergovernmental Panel on Climate Change 2023 report highlighted that climate change has affected water security due to warming, changing precipitation patterns, and greater frequency and intensity of climatic extremes. Sea-level rise, droughts and flooding continue to affect highly populated areas, including coastal populations. As of July 2023, the U.S. National Oceanic and Atmospheric Administration (“NOAA”) indicated that more than 70 million people are currently being affected by droughts and 38 states are experiencing moderate droughts or worse. At the same time, other parts of the country are seeing extreme flooding. According to NOAA, there were 40 tropical cyclone and flooding events in the United States from 2013 to 2023, with an aggregate cost of approximately $730.0 billion.

In coastal regions, rising sea levels and storm surges pose risks to low-lying areas. For example, California has a coastal population of more than 25 million people according to the Office of Coastal Management’s 2023 estimate, which is anticipated to be significantly affected by climate change.

Aging infrastructure. Our nation’s infrastructure — much of it built more than 50 years ago — has deteriorated over the last several decades and is in need of major upgrades and expansions. In its 2021 America’s Infrastructure Report Card, the ASCE graded America’s overall infrastructure as a C- with many of our target markets graded in the Ds. The report estimated that the cumulative needed investment in infrastructure in the United States for the 10 years from 2020 to 2029 was in excess of $2.6 trillion. The ASCE report estimated that by 2039, failure to improve our infrastructure could cost over $10.0 trillion in lost U.S. GDP.

Additionally, the replacement of old, lead pipes is required to protect public health. The EPA estimates that 9 million lead pipes currently deliver drinking water to homes and businesses across the U.S., putting millions at risk for neurological damage and coronary heart disease. Recognized as a serious public health risk, the IIJA includes $15 billion to replace lead pipes across the United States.

Increasing regulations to safeguard public health and address contaminants. Given the widespread exposure to PFAS — harmful, long-lasting chemicals that have been found in our nation’s water supply — state legislatures and the federal government are acting to mitigate the public health impacts and environmental degradation that these chemicals have caused, according to the National Conference for State Legislatures. The IIJA dedicates $10 billion in funding for communities impacted by emerging contaminants in water, including PFAS. In 2021, the EPA released a PFAS roadmap to prevent unsafe new PFAS chemicals from entering the market and protect public health.

As part of this roadmap, in 2023 the EPA took steps to designate PFAS chemicals as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”). CERCLA establishes liability for owners, operators, generators and others, potentially making entities that handle designated PFAS liable for recovery and remediation costs related to PFAS.

Water conservation and efficiency. According to a 2021 Nasdaq report, contracts for water reuse have surpassed those for desalination. Water recycling offers cost savings, lower energy requirements, and enhanced environmental benefits. In addition to being more economical than desalination, it minimizes the necessity for expanding production capacity and transforms wastewater treatment plants from cost centers into profit centers.

Commitment to ESG

We seek to deploy operational best practices for winning, executing, and supporting the work we do, much of which is designed to achieve environmental or social goals such as clean water or building infrastructure to

withstand extreme weather events or other natural disasters. These best practices, tools, and techniques have been developed for key areas of Shimmick’s operations. One of these key areas is Safety, Health, and Environmental (“SH&E”). We seek to achieve SH&E success through a comprehensive, internal program that incorporates SH&E standards and innovative techniques, with the ultimate goal of achieving zero work-related injuries or illnesses and preventing damage to property and the environment. Our SH&E program includes specific guidelines to protect people and the environment and includes environmental compliance maps, environmental impact assessments, environmental management plans, environmental compliance checklists, and a workflow outlining how to manage environmental compliance.

Additionally, we aim to create an inclusive and equitable workplace. For example, in 2021, Shimmick established a mission to empower and support women by providing professional and personal development opportunities. We founded Women at Shimmick, an employee resource group charged with improving the experiences of women at Shimmick, providing programs, events, activities, and other opportunities for professional and personal development for women. The group aims to build awareness of women’s experience among the general employee population, recruit and retain more high performing women, and increase the number of women in leadership positions. In the group’s first year, survey results indicated improvement in key areas including welcoming, leadership and development opportunities, building awareness among the general employee population, and recognition.
