prospectus in a number of different ways and at varying prices. If any underwriters, dealers or agents are involved in the sale of any of the securities, their names and any applicable purchase price, fee, commission or discount arrangement between or among them will be set forth, or will be calculable from the information set forth, in any applicable prospectus supplement. See the sections of this prospectus titled “About this Prospectus” and “Plan of Distribution” for more information. No securities may be sold without delivery of this prospectus and any applicable prospectus supplement describing the method and terms of the offering of such securities. You should carefully read this prospectus and any applicable prospectus supplement before you invest in our securities.

The Offered Securities being offered by the Selling Holders were purchased by the Selling Holders at, or are exercisable at, various prices, certain of which are below the current trading price of our Class A Common Stock. The sale or the possibility of the sale of the Offered Securities being offered pursuant to this prospectus may negatively impact the market price of the Class A Common Stock. See the section titled “Purchase Price Paid by the Selling Holders” for more information.

The Class A Common Stock being offered for resale in this prospectus (including the shares of Class A Common Stock underlying the Class B Common Stock, the Warrants, the Pre-Funded Warrants, the Series A Preferred Stock and the Holdco Rollover Securities) represent approximately 70.1% of our total outstanding Common Stock on a fully diluted basis as of May 5, 2026. The sale of all the securities being offered in this prospectus could result in a significant decline in the public trading price of our Class A Common Stock. Despite such a decline in the public trading prices, the Selling Holders may still experience a positive rate of return on the securities they purchased due to the differences in the trading price and the purchase prices at which they purchased the securities as described herein. See “Risk Factors – Future sales, or the perception of future sales, of our Class A Common Stock by us or our stockholders in the public market could cause the market price for our Class A Common Stock to decline” and “Risk Factors – Certain existing securityholders acquired their securities in the Company at prices below the current trading price of such securities, and may experience a positive rate of return based on the current trading price. Future investors in our Company may not experience a similar rate of return.”

RISK FACTORS

Any investment in our securities involves a high degree of risk. You should carefully consider all of the information contained in this prospectus and any subsequent prospectus supplement, including our financial statements and related notes thereto, before investing in our securities. However, such risks and those discussed elsewhere in any subsequent prospectus supplement are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect us. If any of the risks described in any subsequent prospectus supplement or others not specified therein materialize, our business, financial condition and results of operations could be materially and adversely affected. In that case, you may lose all or part of your investment.

Unless the context otherwise requires, all references in this subsection to the “Company,” “Suncrete,” “we,” “us,” or “our” refer to the business of Suncrete and its consolidated subsidiaries.

Risks Related to Our Operations

There are risks related to our operating strategy.

A key component of our operating strategy is to operate our businesses on a decentralized basis, with local or regional management retaining responsibility for day-to-day operations, profitability and the internal growth of the individual business. If we do not implement and maintain proper overall business controls, this decentralized operating strategy could result in inconsistent operating and financial practices and our overall profitability could be adversely affected.

Our failure to successfully identify, complete, manage and integrate acquisitions could reduce our earnings and slow our growth.

We (including our predecessors) have acquired nine companies since 2016, including the recent Thunder Acquisition, Hope Acquisition and Nelson Acquisition. As part of our strategy to pursue growth opportunities in the Sunbelt region of the United States, we will continue to evaluate strategic acquisition opportunities that we believe have the potential to support and strengthen our business. We cannot predict the timing or size of any future acquisitions. Intense competition exists for acquisition opportunities in our industry. Competition for acquisitions may increase the cost of, or cause us to refrain from, completing acquisitions. We may be unable to identify and complete acquisitions on favorable terms, or at all. Our ability to complete acquisitions is dependent upon, among other things, the willingness of acquisition candidates we identify to sell, our ability to obtain financing or capital, if needed, on satisfactory terms, and, in some cases, regulatory approvals. The investigation of acquisition candidates and the negotiation, drafting and execution of relevant agreements requires substantial management time and attention and substantial costs for accountants, attorneys and others. If we fail to complete any acquisition for any reason, including events beyond our control, the costs incurred up to that point for the proposed acquisition likely would not be recoverable.

Acquisitions typically require integration of the acquired company’s estimation, project management, finance, information technology, risk management, purchasing and fleet management functions. We may be unable to successfully integrate businesses we acquire, including the businesses of the Schwarz Entities, Hope and Nelson Bros. into our existing business, and acquired businesses may not be as profitable as we had expected or at all. Acquisitions involve risks that the acquired business will not perform as expected and that our expectations concerning the value, strengths and weaknesses of the acquired business will prove incorrect.

We have expanded into the Texas and Louisiana markets in connection with the recent Hope Acquisition and Nelson Acquisition, and future acquisition targets may be in geographic regions in which we do not currently operate, which could result in unforeseen operating difficulties and difficulties in coordinating geographically dispersed operations, personnel and facilities. In addition, as we enter into new geographic markets, we have

18

become subject to, and may in the future become subject to, additional and unfamiliar legal and regulatory requirements. Compliance with regulatory requirements may impose substantial additional obligations on us and our management, cause us to expend additional time and resources in compliance activities and increase our exposure to penalties or fines for non-compliance with such additional legal requirements. Our recently completed acquisitions and any future acquisitions could cause us to become involved in labor, commercial, or regulatory disputes or litigation related to any new enterprises and could require us to invest further in operational, financial and management information systems and to attract, retain, motivate and effectively manage local or regional management and additional employees. Upon completion of an acquisition, key members of the acquired company management team may resign, which could require us to attract and retain new management and could make it difficult to maintain customer relationships. Our inability to effectively manage the integration of our completed and future acquisitions could prevent us from realizing expected rates of return on an acquired business and could have a material and adverse effect on our business, financial condition, results of operations, liquidity and cash flows.

We cannot guarantee that we will achieve synergies and cost savings in connection with recent and future acquisitions. Businesses that we may acquire could have unaudited financial statements that were prepared by management and were not independently reviewed or audited, and such financial statements could be materially different if they were independently reviewed or audited. We cannot guarantee that we will continue to acquire businesses at valuations consistent with our prior acquisitions or that we will complete future acquisitions at all. In addition, our results of operations from these acquisitions could, in the future, result in impairment charges for any of our intangible assets, including goodwill or other long-lived assets, particularly if economic conditions worsen unexpectedly.

A significant slowdown or decline in economic conditions, particularly in the southern United States, could adversely impact our results of operations.

We currently sell our ready-mix concrete and sand products to the construction industry in Arkansas, Oklahoma, Texas and Louisiana. A significant slowdown or decline in economic conditions or uncertainty regarding the economic outlook in the United States generally, or in the states in which we operate particularly, could reduce demand in the construction industry in our markets. Construction spending is also affected by changes in interest rates, demographic shifts, industry cycles, employment levels, inflation and other business, economic and financial factors, any of which could contribute to a downturn in construction activities or spending in these states. In addition, any instability in the financial and credit markets could negatively impact our customers’ ability to pay us on a timely basis, or at all, for work on projects already in progress, could cause our customers to delay or cancel projects in our contract backlog and could create difficulties for customers to obtain adequate financing to fund new projects, including through the issuance of municipal bonds.

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, plants and equipment needed to produce our products and provide our services are 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, plants 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 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.

19

Reduced demand for new home construction could adversely affect the residential construction market, which could affect our financial position, operating results and liquidity.

Approximately 36.7% of our revenue for the fiscal year ended December 31, 2025, was from residential construction contractors. Tightening of mortgage lending, mortgage financing requirements or higher interest rates could adversely affect the ability to obtain credit for some borrowers, or reduce the demand for new home construction, which could have a material adverse effect on our business and results of operations. In addition, the limitation of the home mortgage interest and property tax deductions could reduce the demand for new home construction, which could have a material adverse effect on our business and results of operations. Additionally, a decrease in current migration inflow patterns or increased population outflow could reduce the demand for new home construction in the areas in which we operate. A downturn in new home construction could also adversely affect our customers focused on residential construction, possibly resulting in slower payments, higher default rates in our accounts receivable and an overall increase in working capital.

Our operating results may vary significantly from one reporting period to another and may be adversely affected by the cyclical nature of the markets we serve.

The relative demand for our products is a function of the highly cyclical construction industry. As a result, our revenue may be adversely affected by declines in the construction industry generally and in our local markets. Our results also may be materially affected by:

Accordingly, our operating results in any particular quarter may not be indicative of the results that you can expect for any other quarter or for the entire year. Furthermore, negative trends in the ready-mix concrete or aggregates industries or in our geographic markets could have material adverse effects on our business, financial condition, results of operations, liquidity and cash flows.

A significant downturn in the construction industry may result in an impairment of our goodwill.

We test goodwill for impairment if events or circumstances change in a manner that would more likely than not reduce the fair value of a reporting unit below its carrying value. During such impairment testing, we may

20

identify events or changes in circumstances that could indicate the fair value of one or more of our reporting units is below its carrying value. For example, a significant downturn in the construction industry may have an adverse effect on the fair value of our reporting units. A decrease in the estimated fair value of one or more of our reporting units could result in the recognition of a material, non-cash write-down of goodwill.

Our business is seasonal and subject to adverse weather.

Because our business is primarily conducted outdoors, erratic weather patterns, seasonal changes and other weather-related conditions affect our business. Adverse weather conditions, including tornados, cold weather, snow and heavy or sustained rainfall, reduce construction activity, restrict the demand for our products and impede our ability to efficiently deliver concrete. For example, our operating results during 2025 were significantly impacted by unusually heavy and sustained rainfall across Oklahoma and Arkansas during the year, which limited construction activity and reduced delivery days. Adverse weather conditions could also increase our costs and reduce our production output as a result of power loss, needed plant and equipment repairs, delays in obtaining permits, time required to remove water from flooded operations and similar events. In addition, during periods of extended adverse weather or other operational delays, we may elect to continue to pay certain hourly employees to maintain our workforce, which may adversely impact our results of operations. Severe drought conditions can also restrict available water supplies and restrict production. Consequently, these events could adversely affect our business, financial condition, results of operations, liquidity and cash flows.

Our business depends on the availability of sand and aggregate reserves or deposits and our ability to obtain or mine them economically.

Sand and aggregates are a key component of ready-mix concrete. Because sand and aggregates are inexpensive, they are generally cost prohibitive to transport long distances, except in large quantities by railroad or water. As a result, access to local supplies of sand and aggregates, whether mined locally or shipped there by railroad or water, is critical to the operations of our ready-mix concrete business. We may face challenges finding sand and aggregate deposits that we can mine economically with appropriate permits, either within our markets or in long-haul transportation corridors that can economically serve our markets. Due to urban growth, available quarrying locations have been reduced, and communities have imposed restrictions on mining, making aggregates and sand supplies scarce in certain markets. Therefore, our future success is dependent, in part, on our ability to accurately forecast future areas of high growth in order to locate optimal facility sites and on our ability to secure operating and environmental permits to operate at those sites. If we are unable to access economical sources of sand and aggregates either internally or from third parties, our business, financial condition, results of operations, liquidity and cash flows might be materially and adversely affected.

We may lose business to competitors who underbid us, and we may be otherwise unable to compete favorably in our highly competitive industry.

Our competitive position in a given market depends largely on the location and operating costs of our plants and prevailing prices in that market. Price is the primary competitive factor among suppliers for small or less complex jobs, principally in residential construction. However, timeliness of delivery and consistency of quality and service, as well as price, are the principal competitive factors among suppliers for large or complex jobs. Concrete manufacturers like us generally obtain customer contracts through local sales and marketing efforts directed at general contractors, developers, governmental agencies and homebuilders. As a result, we depend on local relationships. We generally do not have long-term sales contracts with our customers.

Our competitors range from small, owner-operated private companies to subsidiaries or operating units of large, vertically integrated manufacturers of concrete, cement and aggregates. Our vertically integrated competitors generally have greater manufacturing, financial and marketing resources than we have, providing them with competitive advantages. Competitors having lower operating costs than we do or having the financial resources to enable them to accept lower margins than we do may have competitive advantages over us for jobs

21

that are particularly price-sensitive. Competitors having greater financial resources than we do to invest in new mixer trucks, build plants in new areas, or pay for acquisitions also may have competitive advantages over us.

If we are unable to accurately estimate the overall risks, revenues or costs on our projects, we may incur contract losses or achieve lower profits than anticipated.

Pricing on fixed unit price contracts is based on approved quantities irrespective of our actual costs, and contracts with a fixed total price require that the work be performed for an agreed-upon price irrespective of our actual costs. We generate profits on fixed unit price and fixed total price contracts only when our revenues exceed our actual costs, which requires us to accurately estimate and control our costs and avoid cost overruns. If our cost estimates are too low or if we do not perform the contract within our cost estimates, then cost overruns may cause us to incur a loss or cause the contract not to be as profitable as we expected. The costs incurred and profit realized, if any, on our contracts can vary, sometimes substantially, from our original projections due to a variety of factors, including, but not limited to:

These and other factors may cause us to incur losses, which could have a material adverse effect on our financial condition, results of operations or liquidity.

We depend on our information technology systems and processes, which are subject to cybersecurity and data leakage risks.

We depend on information technology systems and infrastructure that could be damaged or interrupted by a variety of factors. Any significant breach, breakdown, destruction or interruption of these systems has the

22

potential to negatively affect our operations. We could experience a business interruption, theft of information or reputational damage as a result of a cybersecurity attack, such as the infiltration of a data center, or data leakage of confidential information either internally or through our third-party providers. Although we have invested in the protection of our data and information technology to reduce these risks and periodically test the security of our information systems network, our efforts may not prevent breakdowns or breaches in our systems that could have a material adverse effect on our financial condition, results of operations and liquidity. Similarly, our suppliers rely extensively on computer systems to process transactions and manage their businesses and, thus, are also at risk of, and may be impacted by, cybersecurity attacks. Although we have not experienced a material cybersecurity incident or business interruption event to date, an interruption in the business operations of our suppliers and other third parties with which we do business resulting from a cybersecurity attack could indirectly impact our business operations.

We depend on third parties for concrete equipment and materials essential to operate our business.

We rely on third parties to sell or lease property, plant and equipment to us and to provide us with materials necessary for our operations, including cement, aggregates and other substances. We cannot provide assurance that our favorable working relationships with our suppliers will continue in the future. Also, there have historically been periods of supply shortages in the concrete industry, particularly in a strong economy. If we are unable to purchase or lease necessary properties or equipment, our operations could be severely impacted. If we lose our supply contracts and receive insufficient supplies from third parties to meet our customers’ needs or if our suppliers experience price increases or disruptions to their business, such as labor disputes, supply shortages, or distribution problems, our business, financial condition, results of operations, liquidity and cash flows could be materially and adversely affected.

We use large amounts of electricity and diesel fuel that are subject to potential reliability issues, supply constraints, and significant price fluctuation, which could affect our financial position, operating results and liquidity.

In our production and distribution processes, we consume significant amounts of electricity and diesel fuel. The availability and pricing of these resources are subject to market forces that are beyond our control. Furthermore, we are vulnerable to any reliability issues experienced by our suppliers, which also are beyond our control. Our suppliers contract separately for the purchase of such resources and our sources of supply could be interrupted should our suppliers not be able to obtain these materials due to higher demand or other factors that interrupt their availability. Variability in the supply and prices of these resources could materially affect our financial position, results of operations and liquidity from period to period.

Delays or interruptions of our transportation logistics could affect operating results.

Our products are distributed to our markets by trucks, which are Company-owned. Transportation logistics play an important role in allowing us to supply products to our customers. Any significant delays, disruptions, or the non-availability of our transportation support system could negatively affect our operations. Transportation operations are subject to factors outside of our control, including capacity constraints, high fuel costs and various hazards, including extreme weather conditions and slowdowns due to labor strikes and other work stoppages. If there are material changes in the availability or cost of transportation services, we may not be able to arrange alternative and timely means to transport our products or fuels at a reasonable cost, which could materially affect our financial position and results of operations.

Our continued success requires us to hire, train and retain qualified personnel and subcontractors in a competitive industry.

The success of our business depends on our ability to attract, train and retain qualified, reliable personnel, including, but not limited to, our executive officers and key management personnel. In addition, we rely on

23

project management personnel, skilled plant managers, technicians, drivers and other employees and qualified subcontractors who possess the necessary and required experience and expertise to perform their respective services at a reasonable and competitive rate. Competition for these and other experienced personnel is intense, and it may be difficult to attract and retain qualified individuals with the requisite expertise and within the time frame demanded by our customers. In certain geographic areas, for example, we may not be able to satisfy the demand for our services because of our inability to successfully hire, train and retain qualified personnel. Also, it could be difficult to replace personnel who hold credentials that may be required to perform certain government projects and/or who have significant government contract experience. As some of our executives and other key personnel approach retirement age, we must provide for smooth transitions, which may require that we devote time and resources to identify and integrate new personnel into vacant leadership roles and other key positions. If we are unable to attract and retain enough skilled personnel or effectively implement appropriate succession plans, our ability to pursue projects and our strategic plan may be adversely affected, the costs of executing both our existing and future projects may increase, and our financial performance may decline. In addition, the cost of providing our services, including the extent to which we utilize our workforce, affects our profitability. For example, the uncertainty of contract award timing can present difficulties in matching our workforce size with our contracts. If an expected contract award is delayed or not received, we could incur costs resulting from excess staff or redundancy of facilities that could have a material adverse impact on our business, financial condition and results of operations.

Our results of operations can be adversely affected by labor shortages, turnover and labor cost increases.

Labor is a primary component of operating our business. Several factors may adversely affect the labor force available to us or increase labor costs from time to time, including high employment levels, federal unemployment subsidies and other government regulations. Although we have not experienced material disruptions due to labor shortages to date, we have observed an overall tightening and increasingly competitive labor market. A sustained labor shortage or increased turnover rates within our employee base could lead to increased costs, such as increased overtime to meet demand and increased wage rates to attract and retain employees, and could negatively affect our ability to complete our projects according to the required schedule or otherwise efficiently operate our business. If we are unable to hire and retain employees capable of performing at a high level, or if mitigation measures we may take to respond to a decrease in labor availability, such as overtime and third-party outsourcing, have unintended negative effects, our business could be adversely affected. In addition, we distribute our products and receive raw materials primarily by truck. Reduced availability of trucking capacity due to shortages of drivers and increased fuel costs has caused an increase in the cost of transportation for us and our suppliers. An overall labor shortage, lack of skilled labor, increased turnover or labor inflation could have a material adverse impact on our operations, results of operations, liquidity or cash flows.

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 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 and cause temporary increases in our labor costs as we train new employees. 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. In addition, many of our 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. A failure to comply with these laws or to ensure compliance by our subcontractors could damage our reputation and may cause our

24

customers to cancel contracts with us or to not award future business to us. These factors could adversely affect our results of operations and financial position.

Federal, state and local employment-related laws and regulations could increase our cost of doing business and subject us to fines and lawsuits.

Our operations are subject to a variety of federal, state and local employment-related laws and regulations, including, but not limited to, the U.S. Fair Labor Standards Act, which governs such matters as minimum wages, the Family Medical Leave Act, overtime pay, compensable time, recordkeeping and other working conditions, Title VII of the Civil Rights Act, the Employee Retirement Income Security Act, the Americans with Disabilities Act, the National Labor Relations Act, regulations of the Equal Employment Opportunity Commission, regulations of the Office of Civil Rights, regulations of the Department of Labor, regulations of state attorneys general, federal and state wage and hour laws, and a variety of similar laws enacted by the federal and state governments that govern these and other employment-related matters. Compliance with these evolving federal, state and local laws and regulations could substantially increase our cost of doing business. In recent years, companies have been subject to lawsuits, including class action lawsuits, alleging violations of federal and state law regarding workplace and employment matters, overtime wage policies, discrimination and similar matters, some of which have resulted in the payment of meaningful damages by the defendants. Similar lawsuits may be threatened or instituted against us from time to time, and we may incur damages and expenses resulting from lawsuits of this type, which could have a material adverse effect on our business, financial condition or results of operations. We are currently subject to employee-related legal proceedings in the ordinary course of business. While we believe that we have adequate reserves for those losses that we believe are probable and can be reasonably estimated, the ultimate results of legal proceedings and claims cannot be predicted with certainty.

Our business depends on federal, state and local government spending for public infrastructure construction, and reductions in government funding could adversely affect our results of operations.

During the fiscal year ended December 31, 2025, we generated approximately 15.8% of our construction contract revenues from publicly funded projects and the sale of ready-mix concrete to public customers at the federal, state and local levels. As a result, if publicly funded construction decreases due to reduced federal, state or local funding or otherwise, our financial condition, results of operations and liquidity could be materially adversely affected. In November 2021, the IIJA was signed into law, which provided additional funding for highways, bridges and airports over a five-year period. The IIJA authorized approximately $1.2 trillion in federal spending for transportation and infrastructure projects across the United States. Of this, approximately $51 billion has been earmarked through 2026 for infrastructure development in Arkansas, Oklahoma, Texas and Louisiana. In addition, the Inflation Reduction Act passed in August 2022 has provided funding for a variety of infrastructure-related programs. Although these laws provide for funding for street, highway and other public works projects at historically high levels, the timing, nature and scale of the projects for which these funds under these programs or otherwise will be used remains uncertain given variations in the appropriation processes at the federal and state levels. As a result, we cannot be assured of the existence, timing or amount of future infrastructure funding. Federal infrastructure funding is also subject to uncertainties associated with congressional spending, including the potential impacts of budget deficits, government shutdowns and federal sequestration.

State and local governments fund their infrastructure spending from specially allocated amounts collected from various state and local taxes, respectively, typically fuel taxes and vehicle fees, as well as from voter-approved bond programs. Shortages in state and local tax revenues can reduce the amount spent or delay expenditures on state and local infrastructure projects, respectively. Many state and local governments have experienced state-level funding pressures caused by lower tax revenues and an inability to finance approved projects. Even if federal, state and local funding remains at historical levels, there is no guarantee that we will win bids for projects for which funding is allocated. Any reduction in federal, state or local government infrastructure funding in the areas in which we operate could have a material adverse effect on our results of operations.

25

Governmental regulations, including environmental regulations, may result in increases in our operating costs and capital expenditures and decreases in our earnings.

A wide range of federal, state and local laws, ordinances and regulations apply to our operations, including water usage; land usage; street and highway usage; noise levels; operating hours; and health, safety and environmental matters.

In many instances, we must have various certificates, permits, or licenses to conduct our business. Our failure to maintain required certificates, permits, or licenses or to comply with applicable governmental requirements could result in substantial fines or possible revocation of our authority to conduct some of our operations. Delays in obtaining approvals for the transfer or grant of certificates, permits or licenses, or failure to obtain new certificates, permits or licenses, could impede the implementation of any acquisitions.

Governmental requirements that impact our operations include those relating to air quality, solid and hazardous waste management and cleanup and water quality. These requirements are complex and subject to change. The Trump administration may enact and implement new laws and enhanced regulations that could adversely and materially affect us. Certain laws, such as the Comprehensive Environmental Response, Compensation and Liability Act, can impose strict liability in some cases without regard to negligence or fault, including for the conduct of or conditions caused by others, or for our acts that complied with all applicable requirements when we performed them. Our compliance with amended, new or more stringent requirements, stricter interpretations of existing requirements, or the future discovery of environmental conditions may require us to make unanticipated material expenditures. In addition, we may fail to identify, or obtain indemnification for, environmental liabilities of acquired businesses.

Climate change and related laws and regulations could adversely affect us. The potential impact of climate change on our operations and our customers remains uncertain. The primary risk that climate change poses to our business is the potential for increases in the volume, frequency and intensity of rainfall and tropical storms, which would impair our ability to perform our projects. Climate change could also lead to disruptions in our supply chain, thereby impairing our production capabilities, or the distribution of our products due to major storm events or prolonged adverse conditions, changing temperature levels or flooding from sea level changes. These changes could be severe and could negatively impact demand for our products and services. In addition, governmental initiatives to address climate change could, if adopted, restrict our operations, require us to make capital or other expenditures to comply with these initiatives, increase our costs, impact our ability to compete or negatively impact efforts to obtain permits, licenses and other approvals for existing and new facilities. Our inability to timely respond to the risks posed by climate change and the costs of compliance with climate change laws and regulations could have a material adverse impact on us.

Our operations are subject to various hazards, including natural disasters, that may cause personal injury or property damage for which we have a limited amount of insurance, and our business, operating costs and profitability could be adversely affected.

Operating mixer trucks, particularly when loaded, exposes our drivers and others to traffic hazards. Our drivers are subject to the usual hazards associated with providing services on construction sites, while our plant personnel are subject to the hazards associated with moving and storing large quantities of heavy raw materials. Operating hazards can cause personal injury and loss of life, damage to or destruction of property, plant and equipment and environmental damage. Although we conduct training programs designed to reduce these risks, we cannot eliminate these risks. We maintain insurance coverage against certain workers’ compensation, automobile and general liability risks as part of our overall risk management strategy, and a portion of our contracts require us to maintain specific types and amounts of coverage. Under certain components of our insurance program, we share the risk of loss with our insurance underwriters by maintaining high deductibles subject to aggregate annual loss limitations. This insurance may not be adequate to cover all losses or liabilities we may incur in our operations, and we may not be able to maintain insurance of the types or at levels we deem

26

necessary or adequate, or at rates we consider reasonable. A partially or completely uninsured claim, if successful and of sufficient magnitude, could have a material adverse effect on us.

We maintain only a limited amount of insurance for natural disasters. A natural disaster or other serious disruption to our facilities due to earthquake, hurricane, fire, flood, severe weather or any other cause could substantially disrupt our operations. In addition, we could incur significantly higher costs during the time it takes us to reopen or replace one or more of our facilities, which may not be reimbursed by insurance.

The insurance policies we maintain are subject to varying levels of deductibles. Losses up to the deductible amounts are accrued based on our estimates of the ultimate liability for claims incurred and an estimate of claims incurred but not reported. If we were to experience insurance claims or costs above our estimates, our business, financial condition, results of operations, liquidity and cash flows might be materially and adversely affected.

Increasing insurance claims and expenses could lower our profitability and increase our business risk.

The nature of our business subjects us to product liability, property damage, business interruption, personal injury and workers’ compensation claims. Increased premiums charged by insurance carriers may further increase our expenses as coverage expires or otherwise cause us to raise our self-insured retention amounts. If the number or severity of claims within our self-insured retention increases, we could suffer losses in excess of our reserves. An unusually large liability claim or a string of claims may exceed our insurance coverage or result in direct damages if we were unable or elected not to insure against certain hazards because of high premiums or other reasons. In addition, the availability of, and our ability to collect on, insurance coverage may be subject to factors beyond our control. Further, allegations relating to workers’ compensation violations may result in investigations by insurance regulatory or other governmental authorities, which investigations, if any, could have a direct or indirect material adverse effect on our ability to pursue certain types of business which, in turn, could have a material adverse effect on our business, financial position, results of operations, liquidity and cash flows.

Financial and Liquidity Risks

Our substantial indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations.

Our debt consists primarily of our borrowings under the Amended Credit Agreement, which provides for a fully drawn senior secured first lien Term Loan facility in the aggregate principal amount of $205 million and a $25 million Revolving Credit Facility. As of December 31, 2025, $194.3 million aggregate principal amount remained on the Term Loan and $21.5 million remained available on the Revolving Credit Facility. A significant portion of our cash flow is required to pay interest and principal on our outstanding indebtedness, and we may be unable to generate sufficient cash flow from operations, or have future borrowings available, to enable us to repay our indebtedness or to fund other liquidity needs. Among other consequences, this level of indebtedness could:

27

Volatility in the credit markets, including due to changes in interest rates in the United States, may further increase our interest payments. We have secured overnight financing rate (“SOFR”)-based floating rate borrowings under the Amended Credit Agreement which expose us to variability in interest payments due to changes in the reference interest rates. SOFR has a limited history as a reference rate, and changes in SOFR have, on occasion, been more volatile than changes in other benchmark or market rates. As a result, the amount of interest we may pay on our variable rate indebtedness is difficult to predict. Although the Amended Credit Agreement restricts our ability to incur additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and we could incur substantial additional indebtedness in compliance with these restrictions. This could reduce our ability to satisfy our current obligations and further exacerbate the risks to our financial condition described above.

The Amended Credit Agreement restricts our ability to engage in some business and financial transactions.

The Amended Credit Agreement contains a number of covenants that limit, subject to certain exceptions, our ability to incur additional indebtedness or guarantees, create liens on assets, change our or our subsidiaries’ fiscal year, accounting policies or reporting practices, enter into sale and leaseback transactions, enter into certain restrictive agreements, engage in mergers or consolidations, participate in partnerships and joint ventures, sell assets, incur additional liens, pay dividends or distributions and make other restricted payments, make investments, loans or advances, repay or amend the terms of subordinated indebtedness, prepay or amend the terms of certain other indebtedness in a manner adverse to the lenders or which would shorten the final maturity of such indebtedness, make acquisitions, enter into certain hedge transactions, amend material contracts, engage in certain transactions with affiliates, engage in new lines of business, or issue any new senior preferred equity unless we are in compliance on a pro forma basis with our financial covenants and our pro forma consolidated senior leverage ratio is less than 2.50 to 1.00. The Amended Credit Agreement also requires us to maintain a consolidated fixed charge coverage ratio and a consolidated senior leverage ratio, and the Amended Credit Agreement contains certain customary representations and warranties, affirmative covenants and events of default (including, among others, an event of default upon a change of control). If an event of default occurs, the lenders under the Amended Credit Agreement will be entitled to accelerate amounts due thereunder and take other actions permitted to be taken by a secured creditor. If our indebtedness is accelerated, we cannot be certain that we will have sufficient funds available to pay the accelerated indebtedness or that we will have the ability to refinance the accelerated indebtedness on terms favorable to us or at all.

We may need to raise additional capital in the future, 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 flow from operations, together with borrowing capacity under our Revolving Credit Facility, 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 operating results. 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 Revolving 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 financial position, results of operations, cash flows and liquidity.

28

Unfavorable developments affecting the banking and financial services industry could adversely affect our business, liquidity and financial condition and overall results of operations.

Actual events, concerns or speculation about disruption or instability in the banking and financial services industry, such as liquidity constraints, the failure of individual institutions, or the inability of individual institutions or the banking and financial service industry generally to meet their contractual obligations, could significantly impair our access to capital, delay access to deposits or other financial assets, or cause actual loss of funds subject to cash management arrangements. Similarly, these events, concerns or speculation could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all. Additionally, our customers, critical vendors and business partners also could be adversely affected by these risks as described above, which in turn could result in their committing a breach or default under their contractual agreements with us, their insolvency or bankruptcy, or other adverse effects. Any decline in available funding or access to our cash and liquidity resources, or non-compliance of banking and financial services counterparties with their contractual commitments to us could, among other risks, have material adverse impacts on our ability to meet our operating expenses and other financial needs, could result in breaches of our financial and/or contractual obligations and could have material adverse impacts on our business, financial condition and results of operations.

The unaudited pro forma financial information included elsewhere in this prospectus may not be indicative of our future operating results or financial performance.

The unaudited pro forma financial information included in this prospectus is presented for illustrative purposes only and has been prepared based on a number of assumptions. Accordingly, such pro forma financial information may not be indicative of our future operating results or financial performance, and our actual financial condition and results of operations may vary materially from the unaudited pro forma results of operations and balance sheet contained elsewhere in this prospectus, including as a result of such assumptions not being accurate.

Risks Related to Ownership of our Class A Common Stock and Warrants

An active market for our Class A Common Stock may not continue to develop, which would adversely affect the liquidity and price of our securities.

Prior to the Business Combination, there was no public market for Class A Common Stock. We cannot predict the extent to which investor interest in us will lead to the development of a trading market on Nasdaq or otherwise, or how liquid that market might become. If an active market does not continue develop, stockholders may have difficulty selling any Class A Common Stock. An inactive market may also impair our ability to raise capital by selling our Class A Common Stock and may impair our ability to acquire or make investments in companies for which we may issue equity securities to pay for such acquisitions.

There can be no assurance that the shares of our Class A Common Stock will be able to comply with the continued listing rules of Nasdaq.

Our Class A Common Stock is listed on The Nasdaq Global Market. In order to maintain our listing, we are required to satisfy continued listing requirements. There can be no assurance we will continue satisfying such continued listing requirements, which include that the closing bid price of our Class A Common Stock be at least $1.00 per share, that we have at least 400 round lot holders and at least 750,000 publicly held shares, that the market value of our publicly held securities be at least $5 million, and that we meet one of these standards: stockholders’ equity of at least $10 million; market value of listed securities of at least $50 million; or total assets and total revenues of at least $50 million each in the latest fiscal year or in two of the last fiscal years.

29

If Nasdaq delists our securities from trading on its exchange and the Company is not able to list its securities on another national securities exchange, our securities could be quoted on an over-the-counter market. If this were to occur, the Company could face significant material adverse consequences, including:

As a result of these factors, if our Class A Common Stock is delisted from Nasdaq, the value and liquidity of our Class A Common Stock would likely be significantly adversely affected. A delisting of our Class A Common Stock from Nasdaq could also result in a loss of confidence by investors, employees and/or business partners.

In the event of a delisting, we can provide no assurance that any action taken by us to restore compliance with listing requirements would allow our Class A Common Stock to become listed again, stabilize the market price or improve the liquidity of our Class A Common Stock, prevent our Class A Common Stock from dropping below the Nasdaq minimum bid price requirement or prevent future non-compliance with the listing requirements of Nasdaq.

The price of our Class A Common Stock may change significantly, and you could lose all or part of your investment as a result.

The trading price of our Class A Common Stock is volatile. The stock market recently has experienced extreme volatility. This volatility often has been unrelated or disproportionate to the operating performance of particular companies. Investors may not be able to resell their shares of our Class A Common Stock at an attractive price due to a number of factors, including, but not limited to, the following:

30

These broad market and industry fluctuations may adversely affect the market price of our Class A Common Stock, regardless of our actual operating performance. In addition, price volatility may be greater if the public float and trading volume of our Class A Common Stock is low.

In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If we are involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from our business, regardless of the outcome of such litigation.

The dual class structure of our Common Stock has the effect of concentrating voting control with holders of our Class B Common Stock, which limits the ability of holders of our Class A Common Stock to influence corporate matters.

Pursuant to our Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”), each share of our Class B Common Stock has 10 votes per share, and each share of our Class A Common Stock has one vote per share. As of May 5, 2026, the outstanding Class B Common Stock represented approximately 82.6% of the total voting power of our outstanding Common Stock. The shares of our Class B Common Stock are owned primarily by Dothan Concrete Investors, LLC (“Dothan Concrete”) and Dothan Independent, which are vehicles controlled by the SunTx Group. Because of the 10-to-one voting ratio between our Class B Common Stock and our Class A Common Stock, the holders of our Class B Common Stock collectively control a majority of the combined voting power of our Common Stock and therefore control the outcome of all matters submitted to our stockholders. This concentrated control limits and precludes the ability of holders of shares of our Class A Common Stock to influence corporate matters. Transfers of shares of our Class B Common Stock will generally result in those shares converting into shares of Class A Common Stock, with limited exceptions. The conversion of shares of our Class B Common Stock into Class A Common Stock has the effect, over time, of increasing the relative voting power of each remaining share of Class B Common Stock.

Future sales, or the perception of future sales, of our Class A Common Stock by us or our stockholders in the public market could cause the market price for our Class A Common Stock to decline.

As of May 5, 2026, the Class A Common Stock being offered for resale in this prospectus represented approximately 70.1% of our total outstanding Class A Common Stock on a fully diluted basis (assuming the issuance of the maximum number of shares of Class A Common Stock underlying our outstanding Class B Common Stock, Series A Preferred Stock, Warrants, Pre-Funded Warrants and Holdco Rollover Securities, but excluding the issuance of any additional shares of Class A Common Stock issuable in connection with future earnout payments by us). After the registration statement of which this prospectus is a part is effective, and until such time that it is no longer effective or all of the Offered Securities are sold, the registration statement will permit the resale of the Offered Securities. The resale, or expected or potential resale, of a substantial number of our Class A Common Stock in the public market could adversely affect the market price for our Class A Common Stock and make it more difficult for investors to sell their Class A Common Stock at times and prices

31

that such investors feel are appropriate. Furthermore, we expect that, because there will be a large number of shares registered pursuant to the registration statement of which this prospectus forms a part, the Selling Holders will continue to offer the Offered Securities for a significant period of time, the precise duration of which cannot be predicted. Accordingly, the adverse market and price pressures resulting from the offering of the Offered Securities may continue for an extended period of time.

As restrictions on resale end and the registration statement of which this prospectus forms a part is available for use, the market price of our Class A Common Stock could decline if the holders of currently restricted shares sell them or are perceived by the market as intending to sell them. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. Further, sales of our Class A Common Stock upon expected expiration of resale restrictions could encourage short sales by market participants. Generally, short selling means selling a security, contract or commodity not owned by the seller. The seller is committed to eventually purchase the financial instrument previously sold. Short sales are used to capitalize on an expected decline in the security’s price. As such, short sales of our Class A Common Stock could have a tendency to depress the price of our Class A Common Stock, which could further increase the potential for short sales.

In addition, shares of our Common Stock are reserved for future issuance under the 2026 Plan and will become eligible for sale in the public market once those shares are issued, subject to any applicable vesting requirements, lock-up agreements and other restrictions imposed by law. We expect to file one or more registration statements on Form S-8 under the Securities Act to register shares of our Common Stock or securities convertible into or exchangeable for shares of our Common Stock issued pursuant to the 2026 Plan. Any such registration statements on Form S-8 will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market.

In addition, registration rights we may grant in the future, including in the ordinary course of our business, may further depress market prices if these registration rights are exercised or shares of our Class A Common Stock are sold under resale registration statements. The presence of additional shares trading in the public market may also adversely affect the market price of our Class A Common Stock.

As part of our acquisition business strategy, we have in the past and may in the future acquire businesses and issue equity securities to pay for any such acquisition. We may also raise capital through equity financing in the future. Any such issuances of additional capital stock may cause stockholders to experience significant dilution in their percentage of ownership of our stock and cause the per share value of our Class A Common Stock to decline.

Furthermore, while certain of the Selling Holders may experience a positive rate of return based on the current trading price of our Class A Common Stock, public stockholders may not experience a similar rate of return on the securities purchased in the open market due to potential differences in the purchase prices paid by public stockholders for shares of Class A Common Stock bought in the open market and the Selling Holders in transactions in which they purchased or received their Offered Securities and the current trading price of our Class A Common Stock.

The SunTx Group controls the Company, and their interests may conflict with the interests of the Company or yours in the future.

As of May 5, 2026, Dothan Concrete and Dothan Independent, which are vehicles controlled by SunTx, and Ned N. Fleming III, our Executive Chairman (collectively, the “SunTx Group”), beneficially owned approximately 0.8% of the outstanding shares of Class A Common Stock and 98.8% of the outstanding Class B Common Stock, representing approximately 82.6% of the combined voting power of our Common Stock. Each share of our Class B Common Stock has 10 votes per share, and each share of our Class A Common Stock has one vote per share. Therefore, the SunTx Group has the ability to elect all of the members of our Board and

32

thereby control our policies and operations, including the appointment of management, future issuances of Class A Common Stock or other securities, the payment of dividends, if any, on the Class A Common Stock, our ability to incur or issue debt, amendments to our Certificate of Incorporation or our Amended and Restated By-Laws (the “Bylaws,” and together with the Certificate of Incorporation, our “Organizational Documents”) and entry into extraordinary transactions. This concentration of voting control could deprive investors of an opportunity to receive a premium for their shares of Class A Common Stock as part of a sale of the Company and ultimately might affect the market price of our Class A Common Stock.

In addition, the Company has engaged in related party transactions involving the SunTx Group and certain companies controlled by its members. As a result, the interests of the SunTx Group may not in all cases be aligned with your interests. In addition, the SunTx Group may have an interest in pursuing acquisitions, divestitures and other transactions that, in its judgment, could enhance its investment, even though such transactions might involve risks to you. For example, the SunTx Group could cause us to make acquisitions that increase our indebtedness or cause us to sell revenue-generating assets. SunTx is in the business of making investments in companies and may from time to time acquire and hold interests in businesses that compete directly or indirectly with ours. The Organizational Documents provide that SunTx, any of its affiliates or any director who is not employed by the Company or his or her affiliates do not have a duty to refrain from engaging, directly or indirectly, in the same business activities or similar business activities or lines of business in which we operate. The SunTx Group also may pursue acquisition opportunities that may be complementary to our business, and, as a result, those acquisition opportunities may not be available to us.

So long as the SunTx Group beneficially owns enough shares of our Class B Common Stock, the SunTx Group will continue to effectively control our decisions, even if the number of shares of outstanding Class B Common Stock is limited in proportion to the total number of shares of Common Stock outstanding. Pursuant to the Organizational Documents, shares of our Class B Common Stock may be transferred to an unrelated third party if SunTx consents to such transfer.

If securities or industry analysts do not publish research or reports about our business, if they change their recommendations regarding our Class A Common Stock or if our operating results do not meet their expectations, the price and trading volume of our Class A Common Stock could decline.

The trading market for our Class A Common Stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If no securities or industry analysts commence coverage of us, the trading price for our Class A Common Stock could be negatively impacted. In the event securities or industry analysts initiate coverage, if one or more of the analysts who cover us downgrade our securities or publish unfavorable research about our businesses, or if our operating results do not meet analyst expectations, the trading price of our Class A Common Stock would likely decline. If one or more of these analysts cease coverage of us or fails to publish reports on us regularly, demand for our Class A Common Stock could decrease, which might cause our Class A Common Stock price and trading volume to decline.

We may issue preferred stock with terms that could adversely affect the voting power or value of our Class A Common Stock.

Our Certificate of Incorporation authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over our Class A Common Stock with respect to dividends and distributions, as our Board may determine. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of our Class A Common Stock. For example, we might grant holders of preferred stock the right to elect some number of our directors in all events or upon the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock could affect the residual value of our Class A Common Stock.

33

We are currently an emerging growth company within the meaning of the Securities Act, and to the extent we have taken advantage of certain exemptions from disclosure requirements available to emerging growth companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We are currently an “emerging growth company” within the meaning of the Securities Act, as modified by the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. As a result, our stockholders may not have access to certain information they may deem important. We cannot predict whether investors will find our securities less attractive because we rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company that is either not an emerging growth company or is an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Provisions in our Organizational Documents and Delaware corporate law make it more difficult to effect a change in control, which could adversely affect the price of our Class A Common Stock.

Certain provisions in our Organizational Documents and Delaware corporate law could delay or prevent a change in control, even if that change would be beneficial to our stockholders. The Organizational Documents contain provisions that may make acquiring control of us difficult, including:

34

These provisions also could discourage proxy contests and make it more difficult for stockholders to elect directors and take other corporate actions. As a result, these provisions could make it more difficult for a third party to acquire us, even if doing so would benefit our stockholders, which may limit the price that investors are willing to pay for shares of our Class A Common Stock.

The Certificate of Incorporation designates certain courts as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit the ability of our stockholders to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.

The Certificate of Incorporation provides that, subject to limited exceptions, state courts within the State of Delaware (or, if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware) will 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 fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders; (iii) action asserting a claim against us arising pursuant to any provision of the Delaware General Corporation Law; or (iv) action asserting a claim against us that is governed by the internal affairs doctrine, and that if any action specified above is filed in a court other than a court located within the State of Delaware (each is referred to herein as a foreign action), the claiming party will be deemed to have consented to (a) the personal jurisdiction of state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce the exclusive forum provision described above and (b) having service of process made upon such claiming party by service upon such claiming party’s counsel in the foreign action as agent for such claiming party. In addition, our Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States will be, to the fullest extent permitted by law, the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. These provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and employees. Alternatively, if a court were to find these provisions inapplicable to, or unenforceable in respect of, one or more covered proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business and financial condition.

We are a “controlled company” under Nasdaq listing rules. As a result, our stockholders do not have, and may never have, certain corporate governance protections that are available to stockholders of companies that are not controlled companies.

The SunTx Group controls a majority of the voting power of our Common Stock. Therefore, we are a “controlled company” under Nasdaq listing rules. As a controlled company, we are not 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 be selected by independent directors. Because we intend to continue to take advantage of these exemptions, our stockholders

35

may not have the protections that these rules are intended to provide. Our status as a controlled company could cause our Class A Common Stock to be less attractive to certain investors or otherwise reduce the trading price of our Class A Common Stock.

We do not intend to pay cash dividends on our Class A Common Stock in the foreseeable future, and therefore only appreciation, if any, of the price of our Class A Common Stock will provide a return to our stockholders.

We do not intend to pay cash dividends on our Class A Common Stock in the foreseeable future. Any future determination as to the declaration and payment of cash dividends will be at the discretion of our Board and will depend upon our financial condition, results of operations, contractual restrictions, capital requirements, business prospects and other factors deemed relevant by our Board. As a result, only appreciation of the price of our Class A Common Stock, which may not occur, will provide a return to our stockholders.

A substantial number of shares of our securities are restricted securities and, as a result, there may be limited liquidity for our Class A Common Stock.

A substantial portion of our outstanding shares of Class A Common Stock currently constitute restricted securities and “control” securities for purposes of Rule 144 of the Securities Act or are otherwise subject to a contractual lockup. As a result, there may initially be limited liquidity in the trading market for our Class A Common Stock until these shares are sold pursuant to an effective registration statement under the Securities Act or the shares become available for resale without volume limitations or other restrictions under Rule 144 and are otherwise no longer subject to a lockup agreement. Even once these are no longer restricted or a registration statement for such shares has become effective, the liquidity for our Class A Common Stock may remain limited given the substantial holdings of such stockholders, which could make the price of our Class A Common Stock more volatile and may make it more difficult for investors to buy or sell large amounts of our Class A Common Stock.

Certain existing securityholders acquired their securities in the Company at prices below the current trading price of such securities, and may experience a positive rate of return based on the current trading price. Future investors in our Company may not experience a similar rate of return.

Certain securityholders in the Company, including certain of the Selling Holders, acquired Class A Common Stock and the Warrants at prices below the current trading price of such securities and may experience a positive rate of return based on the current trading price. On May 7, 2026, the closing price of our Common Stock was $15.40 per share.

Given the relatively lower purchase prices that many of our Selling Holders paid to acquire their shares of Class A Common Stock or Warrants compared to their current trading prices, these Selling Holders in some instances may earn a significant positive rate of return on their investment depending on the market price of our Class A Common Stock at the time that such Selling Holders choose to sell their securities. The Selling Holders purchased, or were given as consideration, as applicable, the securities offered for resale at effective purchase prices ranging from significantly below to above current trading prices, as set forth in further detail in the section titled “Purchase Price Paid By the Selling Holders.” Investors who purchase our Class A Common Stock on Nasdaq following our Business Combination may not experience a similar rate of return on the securities they purchased due to differences in the purchase prices and the current trading price.

USE OF PROCEEDS

All of the Offered Securities offered by the Selling Holders pursuant to this prospectus will be sold by the Selling Holders for their respective accounts. We will not receive any of the proceeds from these sales.

We will receive proceeds from the exercise of the Warrants to the extent they are exercised for cash, if any. Assuming the exercise of all of the Warrants being offered pursuant to this prospectus for cash at the $11.50 exercise price per share, we would receive an aggregate of approximately $5.4 million before expenses. However, we will not receive any proceeds from the sale of the shares of Class A Common Stock issuable upon the exercise of the Warrants. We have broad discretion over the use of any proceeds from the exercise of the Warrants, which we anticipate will be used for general corporate purposes.

There is no assurance that the holders of the Warrants will elect to exercise for cash any or all of such Warrants, especially when the trading price of our Class A Common Stock is less than the $11.50 exercise price per share of such Warrants. We believe the likelihood that warrantholders will exercise their respective Warrants, and therefore the amount of cash proceeds that we would receive, is dependent upon the trading price of our Class A Common Stock. If the trading price for our Class A Common Stock is less than the $11.50 exercise price per share of a Warrant, we expect that a warrantholder would not exercise their Warrants. To the extent that any Warrants are exercised on a “cashless basis” under certain conditions, we would not receive any proceeds from the exercise of such Warrants.

As of the date of this prospectus, we have neither included nor intend to include any potential cash proceeds from the exercise of our Warrants in our short-term or long-term liquidity sources or capital resource planning. We do not expect to rely on the cash exercise of Warrants to fund our operations. Instead, we intend to seek additional funds, primarily through the issuance of debt or equity securities for cash to operate our business, including through the business development activities discussed above to continue to support our operations. Therefore, the availability or unavailability of any proceeds from the exercise of our Warrants is not expected to affect our ability to fund our operations. We will continue to evaluate the probability of Warrant exercise over the life of our Warrants and the merit of including potential cash proceeds from the exercise thereof in our liquidity sources and capital resources planning.

The Selling Holders will pay any brokerage fees or commissions and expenses incurred by them for brokerage, accounting, tax or legal services or any other expenses incurred in selling the Offered Securities. We will bear the costs, fees and expenses incurred in effecting the registration of the securities covered by this prospectus, including all registration and filing fees, Nasdaq listing fees and fees and expenses of our counsel and our independent registered public accounting firm.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Previously Completed Business Combination

On October 9, 2025, Haymaker Acquisition Corp. 4, a Cayman Islands exempted company (“Haymaker” or “SPAC”), Haymaker Merger Sub I, Inc. (“Merger Sub I”), Haymaker Merger Sub II, LLC (“Merger Sub II”), Suncrete, Inc. (“PubCo or Suncrete”) and Concrete Partners Holding, LLC (“CPH” or “Company”) entered into a business combination agreement (the “Business Combination Agreement”) pursuant to which (1) at the closing of the transactions contemplated by the Business Combination Agreement (the “Closing”) and following the Domestication (as defined below), Haymaker merged with Merger Sub I, a wholly-owned subsidiary of PubCo (the “Initial Merger”), with Haymaker surviving the Initial Merger as a wholly owned subsidiary of Suncrete (the time at which the Initial Merger became effective, the “Initial Merger Effective Time”) and immediately after, CPH merged into Merger Sub II, a wholly-owned subsidiary of PubCo (the “Acquisition Merger,” together with the Initial Mergers, the “Mergers,” and the time at which the Acquisition Merger became effective, the “Acquisition Merger Effective Time”) resulting in a combined company whereby Haymaker and CPH are wholly-owned subsidiaries of Suncrete, as more fully described in the this prospectus; (2) Haymaker domesticated (the “Domestication”) as a Delaware corporation in accordance with the General Corporation Law of the State of Delaware, the Companies Act (As Revised) of the Cayman Islands and the amended and restated memorandum and articles of association of Haymaker (as amended from time to time); and (3) the other transactions contemplated by the Business Combination Agreement and documents related thereto were consummated (collectively, with the Mergers, the Domestication and all other transactions contemplated by the Business Combination Agreement, the “Business Combination”).

On April 8, 2026, as contemplated by the Business Combination Agreement, Haymaker filed a notice of deregistration with the Cayman Islands Registrar of Companies, together with the necessary accompanying documents, and filed a certificate of incorporation and a certificate of corporate domestication with the Secretary of State of the State of Delaware, pursuant to which Haymaker was domesticated and continued as a Delaware corporation.

Subject to and in accordance with the terms and conditions of the Business Combination Agreement, Initial Merger and Acquisition Merger:

39

Haymaker entered into subscription agreements (the “PIPE Subscription Agreements”) with certain institutional investors (collectively, the “PIPE Investors”), pursuant to which, among other things, Haymaker agreed to (i) issue and sell, in private placements to close immediately prior to or substantially concurrently with the Closing, an aggregate of 14,853,582 shares of Class A Common Stock, par value $0.0001 per share, for a purchase price of $10.00 per share and (ii) 2,525,094 pre-funded common stock purchase warrants, each to purchase one share of Class A Common Stock (the “Pre-Funded Warrants”) at a per share exercise price equal to $0.0001, at a purchase price per Pre-Funded Warrant equal to the Purchase Price less the Exercise Price. Concurrently with the Closing, Suncrete received an aggregate amount of $167.1 million from the PIPE Investors.

40

Suncrete previously entered into a Securities Exchange Agreement (the “Exchange Agreement”) with holders of the its Senior Preferred Units (the “Senior Preferred Units”), pursuant to which Suncrete agreed to issue an aggregate of 26,000 shares of Series A Convertible Perpetual Preferred Stock, par value $0.0001 per share (the “Series A Preferred Stock”), to such Senior Preferred Unit holders in exchange for their Senior Preferred Units (the “Exchange”). On April 8, 2026, the Exchange occurred immediately prior to the closing of the Acquisition Merger, and Suncrete issued 26,000 shares of Series A Preferred Stock to the Senior Preferred Unit holders, following the acceptance by the Secretary of State of the State of Delaware of the Certificate of Designation for the Series A Convertible Perpetual Preferred Stock.

Immediately prior to the Domestication, on April 8, 2026, Haymaker redeemed all of its issued and outstanding public warrants to purchase Class A Ordinary Shares of Haymaker, par value $0.0001 per share (“SPAC Class A Ordinary Shares” and such warrants, the “SPAC Public Warrants”), in exchange for (i) $2.25 in cash and (ii) 0.075 SPAC Class A Ordinary Shares per SPAC Public Warrant (the “Warrant Redemption”).

On April 6, 2026, Haymaker and Suncrete entered into a forward purchase agreement (the “Forward Purchase Agreement”) with each of Harraden Circle Investors, LP (“HCI”), Harraden Circle Special Opportunities, LP (“HCSO”), Harraden Circle Strategic Investments, LP (“HCSI”) and Harraden Circle Concentrated, LP (“HCC”) (with HCI, HCSO, HCSI, HCC, collectively as “Forward Purchase Agreement Seller”) for a prepaid share forward transaction. Pursuant to the terms of the Forward Purchase Agreement, the Forward Purchase Agreement Seller has agreed to purchase up to 5,000,000 Shares (as defined in the Forward Purchase Agreement) in accordance with the terms and conditions therein. The Forward Purchase Agreement provides that the Forward Purchase Agreement Seller will be prepaid an aggregate cash amount (the “Prepayment Amount”) equal to the (i) number of Shares, multiplied by (ii) the per-share redemption price at the closing of the Business Combination (the “Initial Price”). The Forward Purchase Agreement Seller was paid the Prepayment Amount directly from Haymaker’s trust account. From time to time and on any business day on which Nasdaq and commercial banks in the City of New York are open for business (an “Exchange Business Day”), following the closing of the Business Combination (any such date, an “OET Date”), and subject to the terms and conditions therein, the Forward Purchase Agreement Seller shall terminate the Transaction in whole or in part with respect to any number of Shares that are sold by Forward Purchase Agreement Seller on such OET Date by giving notice of such termination and the specified number of Shares (such quantity, the “Terminated Shares”). As of each OET Date, Suncrete will be entitled to from the Forward Purchase Agreement Seller, and the Forward Purchase Agreement Seller shall pay to Suncrete an amount equal to (a) the Initial Price multiplied by (b) the Terminated Shares. The Forward Purchase Agreement maturity date will be the earlier of (a) 6 months after the closing of the Business Combination, or (b) ten Exchange Business Days following the date upon which Suncrete, in its sole discretion, delivers written notice to Forward Purchase Agreement Seller that Suncrete is accelerating the maturity date; provided that such notice will not be effective until three months after the closing of the Business Combination. In addition, Suncrete has the right, in its sole discretion, to extend the maturity up to two times by three months each time by delivering written notice to Forward Purchase Agreement Seller at least ten Exchange Business Days in advance of the then-scheduled maturity date. At maturity, in exchange for the return of the number of remaining Shares under the Forward Purchase Agreement, the Forward Purchase Agreement Seller shall retain an amount equal to (i) the number of Shares multiplied by (ii) the Initial Price. The Forward Purchase Agreement Seller also agreed to waive any redemption rights with respect to the Shares during the term of the Forward Purchase Agreement.

The Business Combination was accounted for as a reverse recapitalization under GAAP. Under this method of accounting, Haymaker was treated as the “acquired” company for accounting purposes. Accordingly, for accounting purposes, the financial statements of the post-combination company represent a continuation of the financial statements of CPH with the Business Combination treated as the equivalent of CPH issuing stock for the net assets of Haymaker, accompanied by a recapitalization. The net assets of Haymaker were stated at historical costs, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination will be presented as those of CPH in future reports of PubCo.

CPH has been determined to be the accounting acquirer based on evaluation of the following facts and circumstances:

Unaudited Pro Forma Condensed Combined Financial Statements

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures and Acquired and Disposed Businesses” to depict the accounting for the transactions described herein (“Transaction Accounting Adjustments”) and do not present any synergies expected to occur as a result of the Business Combination, the Thunder Acquisition, the Hope Concrete Acquisition or the Nelson Bros. Acquisition.

The unaudited pro forma condensed combined financial information presented herein for Suncrete reflects the combination of financial information of Haymaker and CPH, adjusted to give effect to the Business Combination and related transactions, including the Thunder Acquisition and is denoted in the accompanying unaudited pro forma condensed combined financial information as “Suncrete Pro Forma”.

The unaudited pro forma condensed combined balance sheet as of December 31, 2025, gives effect to the Business Combination and related transactions, the Thunder Acquisition, the Hope Concrete Acquisition and the Nelson Bros.

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2025 give effect to the Business Combination and related transactions, the Thunder Acquisition, the Hope Concrete Acquisition and the Nelson Bros. Acquisition as if they had occurred on January 1, 2025, the beginning of the earliest period presented.

The unaudited pro forma condensed combined statement of operations does not reflect a provision for income taxes or any amounts that would have resulted had Suncrete filed consolidated income tax returns during the period presented. The unaudited pro forma condensed combined balance sheet does not reflect any potential deferred taxes as a result of the Business Combination and related transactions, the Thunder Acquisition, the Hope Concrete Acquisition and the Nelson Bros. Acquisition since it is likely that Suncrete will record a valuation allowance against federal and state deferred tax assets given its history of net operating losses.

The unaudited pro forma condensed combined financial information has been presented for informational purposes only and is not necessarily indicative of what Suncrete’s financial position or results of operations actually would have been had the Business Combination and related transactions, the Thunder Acquisition, the Hope Concrete Acquisition or the Nelson Bros. Acquisition been completed as of the dates indicated. In addition, the unaudited pro forma condensed combined financial information does not purport to project the future financial position or operating results of Suncrete following the Business Combination and related transactions, the Thunder Acquisition, the Hope Concrete Acquisition or the Nelson Bros. Acquisition. The actual financial position and results of operations of Suncrete may differ significantly from the pro forma amounts reflected herein due to a variety of factors.

The unaudited pro forma condensed combined financial information does not reflect the benefits of potential cost savings or the costs that may be necessary to achieve such savings, opportunities to increase revenue generation or other factors that may result from the Business Combination and related transactions, the Thunder Acquisition, the Hope Concrete Acquisition or the Nelson Bros. Acquisition and, accordingly, does not attempt to predict or suggest future results.
