Note: See "Disclosure Regarding Forward-Looking Statements" in our Annual Report on Form 10-K included herein for information with respect to forward-looking statements included in this 2024 Annual Report.

1 2024 ANNUAL REPORT Across the country, roads, bridges, airports, rail systems, and other critical infrastructure are in significant need of improvement. Throughout Granite's footprint across the U.S., these infrastructure needs are recognized at the national, state, and local levels. Maintenance on roads and bridges that have been delayed are moving to execution. Projects that will support our nation's growing population are being released for construction. The country recognizes the great needs and is acting.

2 GRANITE Granite has an expanding network of construction and construction materials businesses organized in home markets across the United States serving both the public and private markets. Across our footprint, our expertise allows us to provide infrastructure solutions in a variety of markets as a diversified civil contractor and leading construction materials provider. As America's Infrastructure Company, Granite is well positioned to capitalize on the funding provided by the generational investment in America's infrastructure from the Infrastructure Investment and Jobs Act or IIJA. Robust Market Opportunities Granite serves customers in both the public and private sectors within our reportable segments: Construction and Materials.

6 GRANITE LEADING THROUGH GROWTH AND EXECUTION Granite’s teams produced record results in 2024 by building on the foundations that have driven our success for more than one hundred years. Our history demonstrates that Granite is at its best when we focus on projects in our home markets, use our vertically integrated model as a competitive advantage to grow margin, and rely on our employees — which we believe are the best in the industry — to deliver projects to our customers on time and on budget. These are the pillars that have allowed Granite to flourish for so long; they are the pillars that we built upon when we set out to transform Granite, returning to our past successes with our redesigned Strategic Plan launched in 2022. We will leverage these core strengths as we work to achieve our newly-introduced 2027 financial targets: we have what we believe to be our strongest project portfolio in our history, we continue to grow and strengthen our Construction Materials business, and we are expanding our business into new markets. The Right Projects We have assembled what we believe to be Granite’s strongest project portfolio ever by pursuing the right opportunities within our home markets. State transportation budgets across our geographies remain at record or near record levels fueled by the IIJA. The strength of both the public and private funding environments have fueled the growth of our Committed and Awarded Projects (CAP) over the past three years. We expect further growth while being selective in the projects that we pursue. A key focus is on best value, or collaborative contracting, procurement projects. These types of projects are awarded based

7 2024 ANNUAL REPORT on a combination of contractor qualifications and price, and Granite has demonstrated time and again that we can effectively partner with owners to better collaborate and mitigate construction risks during the design phase of contracts. This allows us to deliver higher quality, complex projects while minimizing disputes and claims. The combination of these best value projects and traditional bid-build procurement type projects in our transformed portfolio has facilitated significant margin expansion in our Construction segment, and we expect to see continued growth and margin expansion through 2027. Investing in Construction Materials We have focused on investment and execution in our Construction Materials business. Three years ago, we shifted the focus of our capital expenditures to aggregate reserves, new materials plants, and plant upgrades. We are already seeing margin improvement from many of these investments, including automation projects at aggregate plants that increase production per labor hour. From 2022 to 2024, we added 426 million tons of aggregate reserves, a 38% increase, and we have improved cash gross profit1 margin by 340 basis points in our Construction Materials business. In 2024, we reorganized our operational structure to better align management of our Construction Materials business, centralizing functions like sales and quality control, and allowing Materials leaders to make strategic decisions to better leverage resources across Granite. In just one year since the reorganization, we have already made significant progress growing margin in our Construction business, with much more expected in the future as we optimize the performance of plants across our portfolio. With a renewed emphasis on maximizing pull-through of aggregates into our Construction business, our Construction Materials business is positioned to support our 2027 financial targets. Kyle T.

8 GRANITE Entering New Markets In 2024, we added to our Southeastern home market with the purchase of materials-led Dickerson & Bowen. Granite has historically grown through acquisitions of materials-led, vertically integrated businesses. We are returning to our roots and will continue to grow through acquisition. There are many opportunities in the market, and we intend to be selective. We will identify and pursue like-minded companies that have strong management teams in growing markets that are immediately EBITDA margin accretive. We expect to strengthen and expand our existing footprints with bolt-on acquisitions, and to enter new geographies with new platform acquisitions. It is an exciting time of growth for Granite. Our decisions have been informed and intentional, and we are executing on our strategy to position Granite for continued revenue growth, adjusted EBITDA margin expansion, and transformative cash flow generation. We believe that we will grow revenue organically 6% to 8% per year through 2027, increase adjusted EBITDA margin to 12% to 14%1, generate operating cash flow margin of 9% to 11%, and achieve free cash flow margin2 of 6% to 8% in 2027. From the federal, state, and local levels, agencies across the nation have recognized the monumental need for new and improved infrastructure, and Granite is uniquely positioned to deliver solutions. As America’s Infrastructure Company, Granite satisfies society’s needs for mobility, power, water, and other essential services that sustain living conditions and improve quality of life. With Granite’s earnings power, cash generation, and strong balance sheet, we believe we are well positioned to capitalize on the long- term generational investments in America’s infrastructure. Thank you for your continued interest in Granite and trust in our leadership. There is much to be excited about, and we are just getting started. Kyle T.

The Company does not provide a reconciliation of forward-looking adjusted EBITDA margin or the most directly comparable forward-looking GAAP measure of net income attributable to Granite Construction Incorporated because the Company cannot predict with a reasonable degree of certainty and without unreasonable efforts certain components or excluded items that are inherently uncertain and depend on various factors. For these reasons, the Company is unable to assess the potential significance of the unavailable information. For additional information, see "Non-GAAP Financial Information" in this 2024 Annual Report. 2 Free cash flow margin is a non-GAAP financial measure and is calculated by subtracting CAPEX from operating cash flow margin. We expect 2027 CAPEX to be 3% of revenue and operating cash flow margin to be 9% to 11% of revenue.

2 Granite Construction Incorporated PART I Item 1. Business Introduction Granite Construction Company was incorporated in 1922. In 1990, Granite Construction Incorporated was formed as the holding company for Granite Construction Company and its wholly-owned and consolidated subsidiaries and was incorporated in Delaware. Unless otherwise indicated, the terms “we,” “us,” “our,” “Company” and “Granite” refer to Granite Construction Incorporated and its wholly-owned and consolidated subsidiaries. We deliver infrastructure solutions for public and private clients primarily in the United States. We are one of the largest diversified, vertically integrated civil contractors and construction materials producers in the United States. Within the public sector, we primarily concentrate on infrastructure projects, including the construction of streets, roads, highways, mass transit facilities, airport infrastructure, bridges, dams, power-related facilities, utilities, tunnels, water well drilling and other infrastructure-related projects. Within the private sector, we perform various services such as site preparation, mining services and infrastructure services for commercial and industrial sites, railways, residential development, energy development, as well as provide construction management professional services. We own and lease aggregate reserves, and we own processing plants that are vertically integrated into our construction operations. We also produce construction materials for sale to third parties. We have vertically integrated operations across Alaska, Arizona, California, Mississippi, Nevada, Oregon, Tennessee, Utah and Washington in addition to regional civil construction home markets in Illinois, Florida and Texas. Our Construction segment also operates national businesses within the Tunnel division, the Rail division, the Federal division, which performs civil construction across the continental United States and Guam, the Industrial & Energy division, which primarily focuses on commercial solar construction projects, and the Layne division, which performs water well drilling, rehabilitation services and mineral exploration services. Operating Structure Our reportable segments are the same as our operating segments and correspond with how our chief operating decision maker, or decision-making group (our “CODM”), regularly reviews financial information to allocate resources and assess performance. We identified our CODM as our Chief Executive Officer and our Chief Operating Officer. Our reportable segments are: Construction and Materials. The Construction segment focuses on construction and rehabilitation of roads, pavement preservation, bridges, rail lines, airports, marine ports, dams, reservoirs, aqueducts, infrastructure and site development for use by the general public and water-related construction for municipal agencies, commercial water suppliers, industrial facilities and energy companies. It also provides construction of various complex projects including infrastructure and site development, mining, public safety, tunnel, solar, battery storage and other power-related projects. The Materials segment focuses on production of aggregates, asphalt concrete, liquid asphalt and recycled materials for internal use in our construction projects and for sale to third parties. See Note 21 of “Notes to the Consolidated Financial Statements” for additional information about our reportable segments. During the first quarter of 2024, we reorganized our operational structure to more closely align with our two reportable segments, Construction and Materials. Previously, leaders within our three former operating groups of California, Central and Mountain managed both Construction and Materials operations within each group. This change allows us to better leverage our expertise within each reportable segment with leadership having direct oversight of their respective segment operations. As a result of the reorganization, we will no longer disclose financial information by operating group. There were no material impacts to our consolidated financial statements and no changes to our reportable segments. Customers Customers in our Construction segment are predominantly in the public sector and include certain federal agencies, state departments of transportation, local transit authorities, county and city public works departments, school districts and developers, utilities and private owners of industrial, commercial and residential sites. Customers of our Materials segment include internal usage by our own construction projects, as well as third-party customers. Our third-party Materials segment customers include, but are not limited to, contractors, landscapers, manufacturers of products requiring aggregate materials, retailers, homeowners, farmers and brokers. The majority of both our public and private customers are located in the United States.

2024 Annual Report 3 During the years ended December 31, 2024, 2023 and 2022, our largest volume customer, including both prime and subcontractor arrangements, was the California Department of Transportation (“Caltrans”). Revenue recognized from contracts with Caltrans during the years ended December 31, 2024, 2023 and 2022 represented $567.6 million (14.2% of total revenue), $458.2 million (13.1% of total revenue) and $348.0 million (10.5% of total revenue), respectively, which was primarily in the Construction segment. Other than Caltrans, none of our customers, including both prime and subcontractor arrangements, had revenue that individually exceeded 10% of total revenue during the years ended December 31, 2024, 2023 or 2022. Business Strategy As America’s Infrastructure Company (TM), Granite satisfies society’s needs for mobility, power, water and other essential services that sustain living conditions and improve quality of life. Across our footprint of regional offices, we provide horizontal civil infrastructure construction services and construction materials products to a diverse base of public, industrial and commercial clients. These clients benefit from our home market strategy which includes local relationships, market intelligence and the resources and expertise of one of the oldest and most respected U.S. contractors and materials producers. Local market knowledge, relationships, and project management expertise, supported by the financial strength of a publicly traded company with a strong balance sheet, provide a sustainable competitive advantage. By diversifying our revenue channels across geographies and clients, and by taking measured risks within our construction capabilities, we simultaneously grow our business and mitigate risk. Supported by proven operating processes, functional support systems and financial governance processes, our growing network of regional businesses focus on local market conditions, client relationships, employee development, workforce capabilities and investment opportunities to drive growth and efficiency within their home markets. Additionally, the following continue to be key objectives in our strategic plan: Selective Bidding We focus our resources on bidding jobs that meet our bidding criteria, which include analyzing the risk of a potential job relative to: (1) available personnel to estimate and prepare the proposal as well as to effectively manage and build the project; (2) project procurement methodology; (3) the competitive environment; (4) our experience with the type of work and the owner; (5) local resources and partnerships; (6) equipment resources; and (7) the size, duration, complexity and expected profitability of the job. Risk-Balanced Growth We intend to grow our business by strategically adding to our client base within our current geographic markets and expanding into new geographic areas both organically and through acquisitions. Growth opportunities are evaluated relative to their incremental impact to the execution risk and profitability profile of our operating portfolio. Vertical Integration We own and lease aggregate reserves and own processing plants that are vertically integrated into our construction operations. By ensuring the availability of these resources through strategic expansion and providing quality products, we believe we have a competitive advantage in many of our markets, as well as a source of revenue and earnings from the sale of construction materials to third parties. We also look for additional vertical integration opportunities that complement our existing construction and materials businesses. We expanded our vertically integrated home markets with the 2024 acquisition of Dickerson & Bowen, Inc. (“D&B”), an aggregates, asphalt and highway construction company serving central and southern Mississippi. Diversification To mitigate the risks inherent in the construction business as the result of general economic factors, we pursue projects: (1) in both the public and private sectors; (2) in diverse end markets such as federal, rail, power and water; (3) for a wide range of clients from the federal government to small municipalities and from large corporations to small private customers; (4) in diverse geographic markets; (5) with procurement methods that include construction management/general contractor (“CM/GC”), construction management at-risk (“CMAR”), progressive design-build, bid-build and design-build; (6) that are executed according to a fixed price, time and materials, cost reimbursable and fixed unit price; and (7) of various size, duration and complexity. Performance-Based Incentives Our incentive compensation plans align with the key objectives outlined in our strategic plan. Managers are incentivized with cash compensation and equity awards payable upon the attainment of pre-established annual financial and non-financial metrics. Code of Conduct and Core Values We strive to maintain high ethical standards through an established Code of Conduct and a company-wide compliance program, while always being guided by our core values which are integrity, safety, excellence, sustainability and inclusion.

4 Granite Construction Incorporated Human Capital Resources Employees We believe our employees are our most valuable resource and are the primary factor in the successful implementation of our business strategies. Significant resources are employed to attract, develop and retain extraordinary and diverse talent and optimize each employee’s capabilities. Our focus on an inclusive work environment, talent development, talent acquisition, and succession planning has allowed us to build a bench of talented employees. Our managerial and supervisory personnel have an average tenure of 12 years with Granite, which demonstrates our workforce’s strong dedication to, and great pride in, our company. On December 31, 2024, we employed approximately 2,300 salaried employees who work in project, functional and business unit management, estimating and administrative capacities, plus approximately 2,100 hourly employees. These totals do not include employees of unconsolidated joint ventures. The total number of hourly personnel fluctuates with the volume of work in progress and is seasonal. During 2024, the number of hourly employees ranged from approximately 2,100 to 4,300. The majority of both our salaried and hourly personnel were located in the United States during 2024. As of December 31, 2024, three of our wholly-owned subsidiaries, Granite Construction Company, Layne Christensen Company and Granite Industrial, Inc., were parties to craft collective bargaining agreements in many areas in which they operate (see Note 16 of the “Notes to the Consolidated Financial Statements”). Health and Safety Employee safety is our greatest priority and safety is ultimately about people, not statistics. Safety is one of our core values and we strive to continuously improve our safety program to better protect our people. We instill our culture of safety through relationship- based safety training, shared knowledge, and engagement at every level of our organization. A core part of our mission will always be to provide a safe and healthy work environment for all our employees. Inclusion Our culture is underpinned by our core values, including an unwavering commitment to inclusion as exemplified by strategies that address our guiding belief that diverse backgrounds, perspectives and experiences enhance creativity and innovation. We have established employee resource groups that serve employees from a variety of backgrounds and we periodically conduct pay analyses to support our commitment to legally-compliant pay practices for similar job functions. We continued to execute on our five-year strategic plan regarding inclusion, which was established in 2020, working toward increased representation of women and minorities throughout the organization (including in leadership) to be reflective of the communities in which we operate. In 2024, we continued to make progress through broadening the diversity of our pool of potential qualified applicants and identifying and addressing any impediments to employment opportunity that may exist. We also increased the number of colleges and universities we are targeting for our pool of qualified applicants. In 2024, we employed 241 interns from 108 colleges and universities. We remain fully committed to fairness and nondiscrimination in our employment practices by ensuring that the decision on who to hire and promote are based purely on merit and made without consideration of race, gender or other protected characteristic. Employee Development and Training The development of our employees is critical to our success and is a key factor in our ability to attract and retain talent. Our people are the foundation of our success, and we encourage every employee to actively participate in their own career growth and development. We offer a wide variety of training opportunities to ensure our employees are supplementing their on-the-job learning with in-person and online courses needed to promote performance and growth. In 2024, our employees completed over 30,000 training courses and more than 300 employees ranging from emerging leaders to senior leaders graduated from our multi-level leadership development program. We have a robust talent and succession planning process and have established specialized programs to accelerate the development of our talent pipeline for critical roles in general management, engineering, project management and operations. On an annual basis, we conduct succession planning reviews with senior leaders focusing on our high performing and high potential talent and succession for critical roles.

2024 Annual Report 5 Employee Engagement We routinely engage independent third parties to conduct cultural and employee engagement surveys. These include corporate culture assessments, as well as real-time feedback on employee engagement and on employee well-being which includes physical, emotional, social and financial health. Compensation and Benefits Our compensation programs are designed to align the compensation of our employees with our financial and safety performance and their individual performance to provide proper incentives to attract, retain and motivate employees to achieve superior results. The structure of our compensation programs balances guaranteed base pay with incentive compensation opportunities. Additionally, all employees are eligible for health insurance, physical, mental and financial wellness programs, paid and unpaid leave, a retirement plan, life insurance and disability/accident coverage. We also offer a variety of voluntary benefits that allow employees to select the options that meet their needs. Sustainability Sustainability is one of our core values and we are committed to contributing to the development of a more sustainable future. We are a participating member of the United Nations Global Compact. Our sustainability objectives encompass corporate social responsibility, environmental stewardship, dependable governance and the creation of enduring economic value. We envision Granite as the leading provider of sustainable infrastructure solutions, differentiated by our pursuit of social, environmental and financial excellence. To attain our objectives, we have a Sustainability department that develops, coordinates and communicates our initiatives across the Company. Our Board of Directors oversees our sustainability program, including how we manage sustainability-related risks in conjunction with our overall Enterprise Risk Management process. We utilize the Global Reporting Initiative and Sustainability Accounting Standards Board standards as frameworks to support performance, tracking and reporting, and responsible business behavior. For climate-related issues, we also utilize the recommendations from the Task Force on Climate-related Financial Disclosures. Within these frameworks, we have selected industry-specific metrics that align with stakeholder expectations, are relevant to our business, and will have the most significant impact. We publish annual Sustainability Reports, which update stakeholders on our performance. Our annual sustainability reports, along with additional information about our sustainability program, can be found on our website at https://www.graniteconstruction.com/company/building-better-future-today. The information on our website and Granite’s Sustainability Report are not incorporated into, and are not part of, this report. Committed and Awarded Projects Committed and Awarded Projects (“CAP”) consists of two components: (1) unearned revenue and (2) other awards. Unearned revenue includes the revenue we expect to record in the future on executed contracts, including 100% of our consolidated joint venture contracts and our proportionate share of unconsolidated joint venture contracts. We generally include a project in unearned revenue at the time a contract is awarded, the contract has been executed and to the extent we believe funding is probable. Contract options and task orders are included in unearned revenue when exercised or issued, respectively. Certain government contracts where funding is appropriated on a periodic basis are included in unearned revenue at the time of the award when it is probable the contract value will be funded and executed. Other awards include the general construction portion of CM/GC contracts and awarded contracts with unexercised contract options or unissued task orders. The general construction portion of CM/GC contracts are included in other awards to the extent contract execution and funding is probable. Contracts with unexercised contract options or unissued task orders are also included in other awards to the extent option exercise or task order issuance is probable, respectively. All CAP is in the Construction segment. Substantially all of the contracts in CAP may be canceled or modified at the election of the customer; however, we have not been materially adversely affected by contract cancellations or modifications in the past (see “Contract Provisions and Subcontracting”). Many projects are added to CAP and completed within the same fiscal year and, therefore, may not be reflected in our beginning or year-end CAP. Our CAP was $5.3 billion and $5.5 billion as of December 31, 2024 and 2023, respectively. Approximately $2.6 billion of the December 31, 2024 unearned revenue is expected to be completed during 2025.

6 Granite Construction Incorporated Competition and Market Trends In both our Construction and Materials segments, we have competitors within the individual markets and geographic areas in which we operate, ranging from small, local companies to larger regional, national and international companies. Although the construction business is highly competitive, there are few, if any, companies which compete in all of our market areas. The degree and type of competition is influenced by the type and scope of construction projects within the individual markets. One of our significant competitive advantages is that we own and lease aggregate reserves and own processing plants that are vertically integrated into our construction operations. The construction materials produced by our Materials segment are used in nearly all types of public and private construction. Significant barriers to entry exist in most markets due to stringent zoning and permitting regulations. Factors influencing competitiveness in both of our segments include price, knowledge of local markets and conditions, financial strength, reputation for quality, aggregate materials availability and machinery and equipment. Factors that also influence competitiveness in our Construction segment are estimating abilities and project management. Many of our Construction segment competitors have the ability to perform work in either the private or public sectors. When opportunities for work in one sector are reduced, competitors tend to look for opportunities in the other sector. This migration has the potential to reduce revenue growth and/or increase pressure on gross profit margins. Capital requirements have not historically had a significant impact on our ability to compete in the marketplace. However, because smaller projects within our Construction segment have not historically required large amounts of capital, the entry by companies possessing acceptable qualifications into this market may be relatively easy. By contrast, larger projects typically require larger amounts of capital that may make entry into the market by future competitors more difficult. Also, aggregate mining and asphalt production require significant capital investment to purchase and maintain the necessary property and equipment which presents a significant barrier to entry into the construction materials market. See “Current Economic Environment and Outlook” under “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” for further information on current market trends. Government Regulations Our business is impacted by environmental, health and safety, government procurement, anti-bribery and other government regulations and requirements. Below is a summary of some of the significant regulations that impact our business. Environmental Our operations are subject to various federal, state, local and foreign laws and regulations relating to the environment, including those relating to: (i) the discharge of materials into the air, such as equipment-related emissions and crystalline silica dust at our aggregate processing facilities; (ii) the discharge of materials into water and land; (iii) the handling and disposal of solid and hazardous waste; (iv) the handling of underground storage tanks; and (v) the cleanup of properties affected by hazardous substances. Certain environmental laws impose substantial penalties for non-compliance and others, such as the federal Comprehensive Environmental Response, Compensation and Liability Act, impose strict, retroactive, joint and several liability upon persons responsible for releases of hazardous substances. We continually evaluate whether we must take additional steps at our locations to ensure compliance with environmental laws and whether we can operate in a more sustainable manner. While compliance with applicable regulatory requirements has not materially adversely affected our operations in the past, there can be no assurance that these requirements will not change, and that compliance will not adversely affect our operations in the future. Government Procurement Approximately 75% of our Construction Segment revenue in 2024 was 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. Our operations are subject to various statutes and certain executive orders, as well as the rules and regulations promulgated by the Occupational Safety and Health Administration and the Mine Safety and Health Administration. In addition, certain of our contracts with government agencies contain minimum Disadvantaged Business Enterprise (“DBE”) participation clauses. These laws and regulations affect how we transact business and, in some instances, impose additional costs on our business operations, which may adversely affect our business, results of operations and financial condition. As further described in “Item 1A. Risk Factors,” violation of specific laws and regulations could lead to fines, contract termination, debarment of contractors and/or suspension of future contracts. Our government customers can also terminate, renegotiate or modify any of their contracts with us at their convenience.

2024 Annual Report 7 Anti-corruption and Bribery We are subject to the Foreign Corrupt Practices Act (“FCPA”). The FCPA prohibits U.S. and other business entities from making improper payments to foreign government officials, political parties or political party officials. We are also subject to the applicable anti-corruption laws in the jurisdictions in which we operate, thus potentially exposing us to liability and potential penalties in multiple jurisdictions. The anti-corruption provisions of the FCPA are enforced by the Department of Justice while other state or federal agencies may seek recourse against us for issues related to the FCPA. In addition, the Securities and Exchange Commission (“SEC”) requires strict compliance with certain accounting and internal control standards set forth under the FCPA. Failure to comply with the FCPA and other laws can expose us and/or individual employees to potentially severe criminal and civil penalties. Such penalties may have a material adverse effect on our business, results of operations and financial condition. We devote resources to the development, maintenance, communication and enforcement of our Code of Conduct, our anti- bribery compliance policies, our internal control processes and compliance related policies. We strive to conduct timely internal investigations of potential violations and take appropriate action depending upon the outcome of the investigation. Contract Provisions and Subcontracting Contracts with our customers are primarily “fixed unit price” or “fixed price.” Under fixed unit price contracts, we are committed to providing materials or services at fixed unit prices (for example, dollars per cubic yard of concrete placed or cubic yard of earth excavated). The percentage of fixed unit price contracts in our unearned revenue was 59.1% and 63.5% at December 31, 2024 and 2023, respectively. While the fixed unit price contract shifts the risk of estimating the quantity of units required for a particular project to the customer, any increase in our unit cost over the expected unit cost in the bid, whether due to inflation, inefficiency, incorrect estimates or assumptions or other factors, is borne by us unless otherwise provided in the contract. Fixed price contracts are priced on a lump-sum basis under which we bear the risk that we may not be able to perform the work for the specified contract amount and any increase in our cost over budget, whether due to inflation, inefficiency, incorrect estimates or assumptions or other factors, will reduce our profit on the project. The percentage of fixed price contracts in our unearned revenue was 33.2% and 30.5% at December 31, 2024 and 2023, respectively. All other contract types represented 7.7% and 6.0% of our unearned revenue at December 31, 2024 and 2023, respectively. Within our Construction segment, we utilize several methods of project delivery including, but not limited to, bid-build, design- build, CM/GC, CMAR and progressive design-build. Unlike traditional bid-build projects where owners first hire a design firm or design a project themselves and then put the project out to bid for construction, the design portion of design-build projects is typically only partially complete when going out to bid. This project delivery method expedites the bidding process for the owner and provides the owner with a single point of responsibility and a single contact for both final design and construction. Under the CM/GC and CMAR delivery methods, we contract with owners to assist during the design phase of the contract with construction efficiencies and risk mitigation, with the understanding that we will negotiate a contract on the construction phase when the collective design nears completion. The progressive design-build delivery method is similar to CM/GC and CMAR; however, we are responsible for the design of the project and will subcontract with a design firm, with the understanding that we will negotiate a contract that includes both the design and construction prices when the collective design nears completion. With the exception of contract change orders and affirmative claims, our construction contracts are primarily obtained through competitive bidding in response to solicitations by both public agencies and private parties and on a negotiated basis as a result of solicitations from private parties. Project owners use a variety of methods to make contractors aware of new projects, including posting bidding opportunities on agency websites, disclosing long-term infrastructure plans, advertising and other general solicitations. Our bidding activity is affected by such factors as the nature and volume of advertising and other solicitations, current CAP, available personnel, current utilization of equipment and other resources and competitive considerations. Our contract review process includes identifying risks and opportunities during the bidding process and managing these risks through mitigation efforts such as contract negotiation, bid/no bid decisions, insurance and pricing. Contracts fitting certain criteria of size, duration and complexity are reviewed by various levels of management and, in some cases, by our Board of Directors or a committee thereof. Bidding activity, CAP and revenue resulting from the award of new contracts may vary significantly from period to period. There are a number of factors that can create variability in contract performance as compared to the original bid. Such factors can positively or negatively impact costs and profitability and can create additional liability to the contractor. The most significant of these include: • changes in costs of labor and/or materials; • subcontractor costs, availability and/or performance issues; • extended overhead and other costs due to owner, weather and other delays; • changes in productivity expectations; • changes from original design on design-build projects;

8 Granite Construction Incorporated • our ability to fully and promptly recover on affirmative claims and back charges for additional contract costs; • a change in the availability and proximity of equipment and materials; • complexity in original design; • length of time to complete the project; • the availability and skill level of workers in the geographic location of the project; • site conditions that differ from those assumed in the original bid; • costs associated with scope changes; and • the customer’s ability to properly administer the contract. The ability to realize improvements on project profitability at times is more limited than the risk of lower profitability. For example, design-build contracts carry additional risks such as those associated with design errors and estimating quantities and prices before the project design is completed. We manage this additional risk by including contingencies in our bid amounts, obtaining errors and omissions insurance and obtaining indemnifications from our design consultants where possible. However, there is no guarantee that these risk management strategies will be successful. Most of our contracts, including those with the government, provide for termination at the convenience of the contract owner, with provisions to pay us for work performed through the date of termination. We have not been materially adversely affected by these provisions in the past. Many of our contracts contain provisions that require us to pay liquidated damages if specified completion schedule requirements are not met, and these amounts could be significant. We act as prime contractor on most of our construction projects. We complete the majority of our projects with our own resources and subcontract specialized activities such as electrical and mechanical work. As prime contractor, we are responsible for the performance of the entire contract, including subcontract work. Thus, we may be subject to increased costs associated with the failure of one or more subcontractors to perform as anticipated. Based on our analysis of their construction and financial capabilities, among other criteria, we may require the subcontractor to furnish a bond or other type of security to guarantee their performance and/or we retain payments, or some portion thereof, in accordance with contract terms until their performance is complete. DBE regulations may require us to use our good faith efforts to subcontract a specified portion of contract work done for governmental agencies to certain types of disadvantaged contractors or suppliers. As with all of our subcontractors, some may not be able to obtain surety bonds or other types of performance security. Joint Ventures We participate in various construction joint ventures with other construction companies of which we are a partner or limited member (“joint ventures”) typically for large, technically complex projects, including design-build 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. Generally, each construction joint venture is formed as a partnership or limited liability company to accomplish a specific project and is jointly controlled by the joint venture partners. We select our joint venture partners based on our analysis of their construction and financial capabilities, expertise in the type of work to be performed and past working relationships, among other criteria. Under each joint venture agreement, one partner is designated as the sponsor. The sponsoring partner typically provides all administrative, accounting and most of the project management support for the project and generally receives a fee from the joint venture for these services. We have been designated as the sponsoring partner in certain of our current joint venture projects and are a non-sponsoring partner in others. In alignment with our strategic plan and project bidding criteria, when entering into new joint venture agreements, we generally insist on being the sponsoring partner. We consolidate joint ventures if we determine that, through our participation, we have a variable interest and are the primary beneficiary as defined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, Consolidation, and related standards. If we have determined that we are not the primary beneficiary of a joint venture but do exercise significant influence, we account for our share of the operations of unconsolidated construction joint ventures on a pro rata basis in revenue and cost of revenue in the consolidated statements of operations. We record the corresponding investment balance in equity in construction joint ventures in the consolidated balance sheets except when a project is in a loss position, the investment balance is recorded as a deficit in unconsolidated construction joint ventures and is included in accrued expenses and other current liabilities in the consolidated balance sheets. We account for non-construction unconsolidated joint ventures under the equity method of accounting in accordance with ASC Topic 323, Investments - Equity Method and Joint Ventures and include our share of the operations in equity in income of affiliates in the consolidated statements of operations and in investment in affiliates in the consolidated balance sheets.

2024 Annual Report 9 We also participate in “line-item” joint venture agreements under which each partner is responsible for performing certain discrete items of the total scope of contracted work. The revenue for each line-item joint venture partners’ discrete items of work is defined in the contract with the project owner and each joint venture partner bears the profitability risk associated only with its own work. There is not a single set of books and records for a line-item joint venture. Each partner accounts for its items of work individually as it would for any self-performed contract. We account for our portion of these contracts as revenue and cost of revenue in the consolidated statements of operations and in relevant balances in the consolidated balance sheets. The agreements with our partner(s) for both construction joint ventures and line-item joint ventures define each partner’s management role and financial responsibility in the project. The joint venture agreements typically provide that our interests in any profits and assets, and our respective share in any losses and liabilities, that may result from the performance of the contracts are limited to our stated percentage interest in the project. However, due to the joint and several nature of the performance obligations under the related owner contracts, if any of the partners fail to perform, we and the remaining partners, if any, would be responsible for performance of the outstanding work (i.e., we provide a performance guarantee). We estimate our liability for performance guarantees for our unconsolidated and line-item joint ventures using estimated partner bond rates, which are Level 2 inputs, and include them in accrued expenses and other current liabilities with a corresponding increase in equity in construction joint ventures in the consolidated balance sheets. We reassess our liability when and if changes in circumstances occur. The liability and corresponding asset are removed from the consolidated balance sheets upon completion and customer acceptance of the project. Circumstances that could lead to a loss under these agreements beyond our stated ownership interest include the failure of a partner to contribute additional funds to the venture in the event the project incurs a loss or additional costs that we could incur should a partner fail to provide the services and resources that it had committed to provide in the agreement. We are not able to estimate amounts that may be required beyond the remaining cost of the work to be performed. These costs could be offset by billings to the customer or by proceeds from our partners’ corporate and/or other guarantees. At December 31, 2024, there was $100.6 million of remaining contract value on unconsolidated and line item construction joint venture contracts, of which $35.6 million represented our share and is included in our CAP and the remaining $65.0 million represented our partners’ share. See Note 9 of “Notes to the Consolidated Financial Statements” for more information. Insurance and Bonding We maintain insurance coverage and limits consistent with industry practice and in alignment with our overall risk management strategy. Policies include general and excess liability, property, pollution, professional, cybersecurity, executive risk, workers’ compensation and employer’s liability. Further, our policies are placed with insurers that we believe are financially stable, often in a layered or quota share arrangement which reduces the likelihood of an interruption or impact to operations. In connection with our business, we generally are required to provide various types of surety bonds that provide an additional measure of security for our performance under certain public and private sector contracts. Our ability to obtain surety bonds depends upon our capitalization, working capital, past performance, management expertise and external factors, including the capacity of the overall surety market. Surety companies consider such factors in light of the amount of our CAP that we have currently bonded and their current underwriting standards, which may change from time to time. The capacity of the surety market is subject to market-based fluctuations driven primarily by the level of surety industry losses and the degree of surety market consolidation. When the surety market capacity shrinks, it results in higher premiums and increased difficulty obtaining bonding, in particular for larger, more complex, multi-year projects throughout the market. To help mitigate this risk, we employ a co-surety structure involving three sureties. Although we do not believe that fluctuations in surety market capacity have affected our ability to grow our business, there is no assurance that it will not significantly affect our ability to obtain new contracts in the future (see “Item 1A. Risk Factors”). Raw Materials We purchase raw materials, including but not limited to, aggregate products, cement, diesel and gasoline fuel, liquid asphalt, natural gas, propane, resin and steel from numerous sources. Our owned and leased aggregate reserves supply a portion of the raw materials needed in our construction projects. The price and availability of raw materials may vary from year to year due to market conditions and production capacities. In recent years, inflation, supply chain and labor constraints have had a significant impact on the global economy including the construction industry in the United States. While it is impossible to fully eliminate the impact of these factors, where practicable, we have applied proactive measures such as fixed forward purchase contracts of oil related inputs, energy surcharges, and adjustment of project schedules for constraints related to construction materials such as concrete.

10 Granite Construction Incorporated Equipment At December 31, 2024 and 2023, we owned the following number of construction equipment and vehicles: December 31, 2024 2023 Heavy construction equipment 2,645 2,457 Trucks, truck-tractors, trailers and vehicles 4,725 4,686 Our portfolio of equipment includes backhoes, barges, bulldozers, cranes, excavators, loaders, motor graders, pavers, rollers, scrapers, trucks, drilling rigs and tunnel boring machines that are used in both of our segments. We pool certain equipment to maximize utilization. We continually monitor and adjust our fleet size so that it is consistent with the size of our business, considering both existing and expected future work. We lease or rent equipment to supplement our portfolio of equipment in response to construction activity cycles. The December 31, 2024 equipment count includes 189 pieces of heavy construction equipment and 206 vehicles from the D&B acquisition. In 2024 and 2023, we purchased $59.2 million and $71.9 million, respectively, of construction equipment and vehicles. Seasonality Our operations are typically affected more by weather conditions during the first and fourth quarters of our fiscal year which may alter our construction schedules and can create variability in our revenues, profitability and the required number of employees.

Risk Factors Set forth below and elsewhere in this report and in other documents we file with the SEC are various risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this report or otherwise adversely affect our business. RISKS RELATED TO OUR BUSINESS • Unfavorable economic conditions may have an adverse impact on our business. Volatility in the global financial system, deterioration in general economic activity, inflation, rising or high interest rates, tariffs, supply chain issues, wars or other geopolitical tensions, other political, social or economic uncertainties, and fiscal, monetary and other policies that federal, state and local governments may enact, including infrastructure spending or deficit reduction measures, may have an adverse impact on our business, financial position, results of operations, cash flows and liquidity. In particular, low tax revenues, budget deficits, financing constraints, including timing of long-term federal, state and local funding releases,

12 Granite Construction Incorporated and competing priorities could negatively impact the ability of government agencies to fund existing or new infrastructure projects in the public sector. These factors could have a material adverse effect on the financial market 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 strategy. • We work in a highly competitive marketplace. We have multiple competitors in all the areas in which we work, and some of our competitors are larger than we are and may have greater resources than we do. Government funding for public works projects is limited, contributing to competition. An increase in competition may result in a decrease in new awards, a decrease in profit margins, or both. In addition, should downturns in residential and commercial construction activity occur, the competition for available public sector work would intensify, which could impact our revenue, CAP and profit margins. • Fixed price and fixed unit price contracts subject us to the risk of increased project cost. As more fully described in “Contract Provisions and Subcontracting” under “Item 1. Business,” the profitability of our fixed price and fixed unit price contracts can be adversely affected by a number of factors, including, among others, inflation, tariffs, inefficiency and incorrect estimates or assumptions, that can cause our actual costs to materially exceed the costs estimated at the time of our original bid. This could result in reduced profits or a loss for that project and there could be a material adverse impact to our business, results of operations and financial condition. • We derive a substantial amount of our revenue from federal, state and local government agencies, and any disruption in government funding or in our relationship with those agencies could adversely affect our business. For the year ended December 31, 2024, approximately 75% of our construction revenue was funded by federal, state and local government agencies and authorities. A significant amount of this revenue is derived under multi- year contracts, many of which are appropriated on an annual basis. As a result, at the beginning of a project, the related contract may be only partially funded, and additional funding is normally committed only as appropriations are made in each subsequent year. The success and further development of our business depends, in large part, upon the continued funding of these government programs, and upon our ability to obtain contracts and perform well under these programs. A significant reduction in government spending, the absence of a bipartisan agreement on the federal government budget, a partial or full federal government shutdown or a change in budgetary priorities could reduce demand for our services, cancel or delay projects and have a material adverse effect on our business, results of operations and financial condition. There are several additional factors that could cause government agencies or authorities to delay or cancel programs, to reduce their orders under existing contracts, to exercise their rights to terminate contracts or not to exercise contract options for renewals or extensions. Such factors, which include the following, could have a material adverse effect on our business, financial condition and results of operations or the timing of contract payments from government agencies or authorities: o the failure of the U.S. government to complete its budget and appropriations process before its fiscal year-end; o changes in and delays or cancellations of government programs, procurements, requirements or appropriations; o budget constraints or policy changes resulting in delay or curtailment of expenditures related to the services we provide; o re-competes of government contracts; o the timing and amount of tax revenue received by federal, state and local governments, and the overall level of government expenditures; o curtailment in the use of government contracting firms; o delays associated with insufficient numbers of government staff to oversee contracts; o the preference by government agencies for contracting with small and disadvantaged businesses; o competing political priorities and changes in the political climate regarding the funding or operation of the services we provide; o the adoption of new laws or regulations affecting our contracting relationships with the federal, state or local governments; o unsatisfactory performance on government contracts by us or one of our subcontractors, negative government audits or other events that may impair our relationship with federal, state or local governments; o a dispute with or improper activity by any of our subcontractors; and o general economic or political conditions. • Our U.S. federal government contracts may give government agencies the right to modify, delay, curtail, renegotiate or terminate existing contracts at their convenience at any time prior to their completion, which could have a material adverse effect on our business, financial condition and results of operations. U.S. federal government projects in which we participate as a contractor or subcontractor may extend for several years. Generally, government contracts include the right to modify, delay, curtail, renegotiate or terminate contracts and subcontracts at the

2024 Annual Report 13 government’s convenience any time prior to their completion. Any decision by a U.S. federal government client to modify, delay, curtail, renegotiate or terminate our contracts at their convenience could have a material adverse effect on our business, financial condition and results of operations. • Our failure to win new contracts and renew existing contracts with private and public sector clients could have a material adverse effect on our business, financial condition and results of operations. Our business depends on our ability to win new contracts and renew existing contracts with private and public sector clients. Contract proposals and negotiations are complex and frequently involve a lengthy bidding and selection process, which is affected by a number of factors. These factors include market conditions, financing arrangements and required governmental approvals. If negative market conditions arise, or if we fail to secure adequate financial arrangements or the required government approval, we may not be able to pursue certain projects, which could have a material adverse effect on our business, financial condition and results of operations. • The U.S. government may adopt new contract rules and regulations or revise its procurement practices in a manner adverse to us at any time. From time to time, new laws and regulations are enacted, and government agencies adopt new interpretations and enforcement priorities relative to laws and regulations already in effect. Legislation, regulations and initiatives dealing with procurement reform as well as any resulting shifts in the buying practices of U.S. government agencies could have adverse effects on government contractors, including us. • The timing of new contracts and termination of existing contracts may result in unpredictable fluctuations in our cash flows and financial results. A substantial portion of our revenues are derived from project-based work that is awarded through a competitive bid process. It is generally difficult to predict the timing and geographic distribution of the projects that we will be awarded. The selection of, timing of, or failure to obtain projects, delays in awards of projects, the re-bidding or termination of projects due to budget overruns, cancellations of projects or delays in completion of contracts could result in the under-utilization of our assets, including our fleet of construction equipment, which could lower our overall profitability and reduce our cash flows. Even if we are awarded contracts, we face additional risks that could affect when, or whether, work will begin. This can present difficulty in matching workforce size and equipment location with contract needs. In some cases, we may be required to bear the cost of a ready workforce and equipment that is larger than necessary, which could have a material adverse effect on our business, financial condition and results of operations. If an expected contract award or the related work release is delayed or not received, we could incur substantial costs without receipt of any corresponding revenues. Moreover, construction projects for which our services are contracted may require significant expenditures by us prior to receipt of relevant payments from the customer. Finally, the winding down or completion of work on significant projects that were active in previous periods will reduce our revenue and earnings if such significant projects have not been replaced in the current period. Many of our contracts may be canceled upon short notice, typically 30 to 90 days, even if we are not in default under the contract, and we may be unsuccessful in replacing contracts, resulting in a decrease in our revenue, net income and liquidity. Certain of our customers assign work to us on a project-by-project basis under master service agreements. Under these agreements, our customers often have no obligation to assign a specific amount of work to us. Our operations could decline significantly if the anticipated volume of work is not assigned to us or is canceled. Many of our contracts, including our master service agreements, are open to competitive bidding at the expiration of their terms. There can be no assurance that we will be the successful bidder on our existing contracts that come up for re-bid. • Design-build contracts subject us to the risk of design errors and omissions. Design-build is a common method of project delivery as it provides the owner with a single point of responsibility for both design and construction. We generally subcontract design responsibility to architectural and engineering firms. However, in the event of a design error or omission causing damages, there is risk that the subcontractor or their errors and omissions insurance would not be able to absorb the liability. In this case, we may be responsible, resulting in a potentially material adverse effect on our business, results of operations and financial condition. • Many of our contracts have penalties for late completion. In some instances, including many of our fixed price contracts, we guarantee that we will complete a project by a certain date. If we subsequently fail to complete the project as scheduled, we may be held responsible for costs resulting from the delay, generally in the form of contractually agreed-upon liquidated damages. To the extent these events occur, the total cost of the project could exceed our original estimate and we could experience reduced profits or a loss on that project and there could be a material adverse impact to our business, results of operations and financial condition.

14 Granite Construction Incorporated • Our failure to adequately recover on affirmative claims brought by us against project owners or other project participants (e.g., back charges against subcontractors) for additional contract costs could have a negative impact on our liquidity and future operations. In certain circumstances, we assert affirmative claims to which we believe we are entitled against project owners, 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 types of affirmative claims occur due to matters such as delays or changes from the initial project scope, both of which may result in additional costs. Often, these affirmative claims can be the subject of lengthy arbitration or litigation proceedings, and it is difficult to accurately predict when and on what terms they will be fully resolved. For additional information, see “—Accounting for our revenues and costs involve significant estimates” risk factor below. The potential gross profit impact of recoveries for affirmative claims may be material in future periods when they, or a portion of them, become probable and estimable or are settled. When these types of events occur, we use working capital to cover cost overruns pending the resolution of the relevant affirmative claims and may incur additional costs when pursuing such potential recoveries. A failure to recover on these types of affirmative claims promptly and fully could have a negative impact on our business, results of operations and financial condition. In addition, while clients and subcontractors may be obligated to indemnify us against certain liabilities, such third parties may refuse or be unable to pay us. • 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, and our inability to obtain such coverage could have an adverse impact on our ability to procure new work, which could have a material adverse effect on our business, results of operations and financial condition. • An inability to obtain bonding could have a negative impact on our operations and results. As more fully described in “Insurance and Bonding” under “Item 1. Business,” we generally are required to provide surety bonds securing our performance under the majority of our public and private sector contracts. Our inability to obtain reasonably priced surety bonds in the future and, while we monitor the financial health of our insurers and the insurance market, catastrophic events could reduce available limits or the breadth of coverage, both of which could significantly affect our ability to be awarded new contracts and could, therefore, have a material adverse effect on our business, results of operations and financial condition. If we are not able to maintain a sufficient level of bonding capacity in the future, it could preclude our ability to bid for certain contracts or successfully contract with some customers. Additionally, even if we continue to be able to access bonding capacity to sufficiently bond future work, we may be required to post collateral to secure bonds, which would decrease the liquidity we would have available for other purposes. • We use certain commodity products that are subject to significant price fluctuations. We are exposed to various commodity price risks, including, but not limited to, diesel fuel, natural gas, propane, steel, cement and liquid asphalt 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 due to a number of factors, including inflation and tariffs. 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. At times we enter into supply agreements or pre-purchase commodities to secure pricing and use financial contracts to further manage a portion of the price risk. Significant price fluctuations could have a material adverse effect on our business, results of operations and financial condition. • Weather can significantly affect our revenues and profitability. Our ability to perform work is significantly affected by weather conditions such as precipitation and temperature. Changes in weather conditions can cause delays and otherwise significantly affect our project costs. The impact of weather conditions can result in variability in our quarterly revenues and profitability, particularly in the first and fourth quarters of the year. • Force majeure events, including natural disasters 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, as well as terrorist actions, could negatively impact the economies in which we operate. We typically negotiate contract language where we are allowed certain relief from force majeure events in private client contracts and review and attempt to mitigate force majeure events

2024 Annual Report 15 in both public and private client 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, which could have a material adverse effect on our business, results of operations and financial condition. • Public health events, including health epidemics or pandemics or other contagious outbreaks, could negatively impact our business, financial condition and results of operations. Our ability to perform work may be significantly affected by public health events. If a public health epidemic or pandemic or other contagious outbreak, including COVID-19, interferes with our ability, or that of our employees, contractors, suppliers, customers and other business partners to perform our and their respective responsibilities and obligations relative to the conduct of our business, our operations may be affected, which could have a material adverse effect on our business, results of operations and financial condition. • Our CAP is subject to unexpected adjustments and cancellations and could be an uncertain indicator of our future earnings. We cannot guarantee that the revenues projected in our CAP will be realized or, if realized, will be profitable. Projects reflected in our CAP may be affected by project cancellations, scope adjustments, time extensions or other changes. Such changes may adversely affect the revenue and profit we ultimately realize on these projects. • Economic factors, including inflation, rising and/or high interest rates and tariffs could have an adverse effect on our business, financial condition and results of operations. Our costs were and may continue to be subject to significant inflationary pressures and may be subject to tariff-related price increases, and 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 financial position, results of operations, cash flows and liquidity. In addition, increases in or sustained higher interest rates will result in higher interest expense related to borrowings under our Fourth Amended and Restated Credit Agreement, as amended (the “Credit Agreement”), which could have a material adverse effect on our business, results of operations and financial condition. • As part of our growth strategy, we have made and may make future acquisitions, and acquisitions involve many risks and uncertainties. These risks and uncertainties include: o our ability to complete acquisitions in accordance with our expected plans, on terms and conditions acceptable to us or our anticipated time frame, or at all; o difficulties identifying all significant risks during our due diligence activities; o that acquisitions involve significant costs and require the time and attention of our management, which may divert management’s attention from ongoing operations; o potential difficulties and increased costs associated with completion of any assumed construction projects; o our ability to successfully manage or achieve the results we expect to experience from the acquisitions and that we may lose key employees or customers of the acquired companies; o assumption of liabilities of an acquired business, including liabilities that were unknown at the time the acquisition was negotiated; o difficulties related to integrating the operations and internal controls, assimilating personnel, services, and systems of an acquired business and to assimilating marketing and other operational capabilities; o increased burdens on our staff and on our administrative, internal control and operating systems, which may hinder our legal and regulatory compliance activities; o if we issue additional equity securities, such issuances could have the effect of diluting our earnings per share as well as our existing shareholders’ individual ownership percentages in the Company; o the recording of goodwill or other non-amortizable intangible assets that will be subject to subsequent impairment testing and potential impairment charges, as well as amortization expenses related to certain other intangible assets; and o while we often obtain indemnification rights from the sellers of acquired businesses, such rights may be difficult to enforce and the indemnitors may not have the ability to financially support the indemnity. Failure to successfully manage and integrate acquisitions could harm our business, results of operations and financial condition. • As part of our strategy, we may make divestitures, and divestitures involve many risks and uncertainties. These risks and uncertainties include: o our ability to locate suitable acquirers for our divestitures; o our ability to complete the divestitures in accordance with our expected plans or anticipated time frame, or at all; o our ability to complete the divestitures on terms and conditions acceptable to us;

16 Granite Construction Incorporated o difficulties separating the assets and personnel related to businesses that we expect to divest from the businesses we expect to retain; o that divestitures involve significant costs and require the time and attention of our management, which may divert management’s attention from ongoing operations; o our ability to successfully cause a buyer of a divested business to assume the liabilities of that business, or even if such liabilities are assumed, we may have difficulties enforcing our rights, contractual or otherwise against the buyer; o the need to obtain regulatory approvals and other third-party consents, which potentially could disrupt customer and vendor relationships; o potential additional tax obligations or the loss of tax benefits; o the divestiture could negatively impact our profitability because of losses that may result from a sale, the loss of revenue or a decrease in cash flows; and o following the completion of a divestiture, we may have less diversity in our business and in the markets we serve as well as our client base. Failure to successfully manage divestitures may generate fewer benefits than expected and could harm our business, results of operations and financial condition. • In connection with acquisitions or divestitures, we may become subject to liabilities. In connection with any acquisitions, we may acquire liabilities or defects such as legal claims, including but not limited to, third party liability and other tort claims; claims for breach of contract; employment-related claims; environmental, health and safety liabilities, conditions or damage; permitting, regulatory or other compliance with law issues; or tax liabilities. If we acquire any of these liabilities, and they are not adequately covered by insurance or an enforceable indemnity or similar agreement from a creditworthy counterparty, we may be responsible for significant out-of-pocket expenditures. In connection with any divestitures, we may incur liabilities for breaches of representations and warranties or failure to comply with operating covenants under any agreement for a divestiture. We may also retain exposure on financial or performance guarantees, contractual, employment, pension and severance obligations or other liabilities of the divested business and potential liabilities that may arise under law because of the disposition or the subsequent failure of an acquiror. As a result, performance by the divested businesses or other conditions outside of our control could have a material adverse effect on our business, financial condition and results of operations. In addition, we may indemnify a counterparty in a divestiture for certain liabilities of the divested business or operations subject to the divestiture transaction. These liabilities, if they materialize, could have a material adverse effect on our business, results of operations and financial condition. RISKS RELATED TO OUR HUMAN CAPITAL, JOINT VENTURES AND SUBCONTRACTORS • Our success depends on attracting and retaining qualified personnel, joint venture partners 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 reputation, relationships and/or ability to profitably execute our work could be adversely impacted. • Failure to maintain safe work sites could result in significant losses. Construction, mining and maintenance sites are potentially dangerous workplaces and often put our employees and others in close proximity with mechanized equipment, moving vehicles, chemical and manufacturing processes, and highly regulated materials. 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, as well as expose ourselves to possible litigation. Our failure to maintain adequate safety standards through our safety programs could result in reduced profitability or the loss of projects or clients, and could have a material adverse impact on our financial position, results of operations, cash flows and liquidity. • Strikes or work stoppages could have a negative impact on our operations and results. We are party to collective bargaining agreements covering a portion of our craft workforce. Although strikes or work stoppages have not had a significant impact on our operations or results in the past, such labor actions could have a significant impact on our operations and results if they occur in the future. • Failure of our subcontractors to perform as anticipated could have a negative impact on our results. As further described in “Contract Provisions and Subcontracting” under “Item 1. Business,” we subcontract portions of many of our contracts to specialty subcontractors, but we are ultimately responsible for the successful completion of their work.

2024 Annual Report 17 Although we seek to require bonding or other forms of guarantees, we are not always successful in obtaining those bonds or guarantees from our higher-risk subcontractors. We may be responsible for the failures on the part of our subcontractors to perform as anticipated, resulting in a potentially adverse impact on our cash flows and liquidity. In addition, the total costs of a project could exceed our original estimates and we could experience reduced profits or a loss for that project, which could have an adverse impact on our financial position, results of operations, cash flows and liquidity. • Our joint venture contracts subject us to risks and uncertainties, some of which are outside of our control. As further described in Note 1 of “Notes to the Consolidated Financial Statements” and in “Joint Ventures” under “Item 1. Business,” we perform certain construction contracts as a limited or minority member of joint ventures. Participating in these arrangements exposes us to risks and uncertainties, including the risk that if our partners fail to perform under joint and several liability contracts, we could be liable for completion of the entire contract. In addition, if our partners are not able or willing to provide their share of capital investment to fund the operations of the venture, there could be unanticipated costs to complete the projects, financial penalties or liquidated damages. These situations could have a material adverse effect on our financial position, results of operations, cash flows and liquidity. To the extent we are not the controlling partner, we have limited control over many of the decisions made with respect to the related construction projects. These joint ventures may not be subject to the same compliance requirements, including those related to internal control over financial reporting. While we have controls to mitigate the risks associated with reliance on their control environment and financial information, to the extent the controlling partner makes decisions that negatively impact the joint venture or internal control problems arise within the joint venture, it could have a material adverse impact on our business, financial position, results of operations, cash flows and liquidity. • We may be unable to identify and contract with qualified DBE contractors to perform as subcontractors. Certain of our government agency projects contain minimum DBE participation clauses. Although we have programs in place to ensure compliance, if we 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 financial position, results of operations, cash flows and liquidity. • We may be required to contribute cash to meet our unfunded pension obligations in certain multi-employer plans. As of December 31, 2024, three of our wholly-owned subsidiaries, Granite Construction Company, Layne Christensen Company and Granite Industrial, Inc., participate in various domestic multi-employer pension plans on behalf of union employees. Union employee benefits generally are based on a fixed amount for each year of service. We are required to make contributions to certain plans in amounts established under collective bargaining agreements. Pension expense is recognized as contributions are made. The domestic multi-employer pension plans are subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). Under ERISA, a contributor to a multi-employer plan may be liable, upon termination or withdrawal from a plan, for its proportionate share of a multi-employer plan’s unfunded vested liability. While we currently have no intention of withdrawing from a plan and unfunded multi-employer pension obligations have not significantly affected our operations in the past, there can be no assurance that we will not be required to make material cash contributions to one or more of these plans to satisfy certain underfunded benefit obligations in the future. RISKS RELATED TO LEGAL, REGULATORY, ACCOUNTING AND TAX ISSUES • Government contractors are subject to suspension or debarment from government contracting. Government contracts expose us to a variety of risks that differ from those associated with private sector contracts. Various statutes and executive orders to which our operations are subject provide for mandatory suspension and/or debarment of contractors in certain circumstances involving statutory violations. In addition, the Federal Acquisition Regulation 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 financial position, results of operations, cash flows and liquidity. • We are involved in lawsuits, legal proceedings and indemnity claims in the ordinary course of our business and may in the future be subject to other litigation, legal proceedings and claims, and, if any of these are resolved adversely against us, it could harm our business, financial condition and results of operations. Any litigation, other legal proceedings or indemnity claim could result in an unfavorable judgment that may not be reversed upon appeal or in payments of substantial monetary damages or fines, or we may decide to settle lawsuits on similarly unfavorable terms, any

18 Granite Construction Incorporated of which could adversely affect our business, financial condition and results of operations. We could also suffer an adverse impact on our reputation and a diversion of management’s attention and resources, which could have a material adverse effect on our business, financial condition and results of operations. • Government contracts generally have strict regulatory requirements. Approximately 75% of our construction-related revenue in 2024 was 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. Claims for civil or criminal fraud may be brought for violations of regulations, requirements or statutes. We may also be subject to qui tam litigation brought by private individuals on behalf of the government under the Federal Civil 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 Occupational Safety and Health Administration, 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 financial position, results of operations, cash flows and liquidity. • We are subject to environmental, health and safety and other regulation. As more fully described in “Government Regulations” under “Item 1. Business,” we are subject to a number of federal, state, local and foreign laws and regulations relating to the environment, including the remediation of soil and groundwater contamination, emission and discharge of materials into the environment, reclamation and closure of operations, workplace health and safety and a variety of socioeconomic requirements and are required to obtain and maintain a number of environmental approvals, permits and financial assurances. Noncompliance with such laws, regulations, approvals, permits and financial assurances can result in, among other things, substantial penalties, or termination or suspension of government contracts or our operations as well as civil and criminal liability. In addition, some environmental laws and regulations impose strict, joint and several liability and responsibility on present and former owners, operators or users of facilities and sites, and entities that disposed or arranged for the disposal of hazardous substances at a third-party site, for contamination at such facilities and sites, without regard to causation or knowledge of contamination. We occasionally evaluate various alternatives with respect to our facilities, including possible dispositions or closures. Investigations undertaken in connection with these activities may lead to discoveries of contamination that must be remediated, and closures of facilities may trigger compliance requirements, including reclamation requirements, that may not be applicable to operating facilities. Environmental, health and safety requirements, laws and regulations are becoming increasingly more stringent and there can be no assurance that these requirements, laws or regulations will not change and that compliance with these requirements, laws and regulations will not materially adversely affect our operations in the future. Furthermore, from time to time, we have been involved in remediation activities and we cannot provide assurance that existing or future circumstances or developments with respect to contamination will not require us to make significant remediation or restoration expenditures. • Increasing restrictions on securing aggregate reserves could negatively affect our future operations and results. Tighter regulations and the finite nature of property containing suitable aggregate reserves are making it increasingly challenging and costly to secure aggregate reserves. Although we have thus far been able to secure reserves to support our business, our financial position, results of operations, cash flows and liquidity may be adversely affected by an increasingly difficult permitting process. • Accounting for our revenues and cost involves significant estimates. As further described in “Critical Accounting Estimates” under “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and in “Use of Estimates in Preparation of Financial Statements,” and “Revenue Recognition” within Note 1 of the “Notes to the Consolidated Financial Statements,” accounting for our contract-related revenues and costs, as well as other expenses requires management to make a variety of significant estimates and assumptions. These assumptions and estimates may change significantly in the future and could result in the reversal of previously recognized revenue and profit. Such changes could have a material adverse effect on our financial position and results of operations. • A change in tax laws or regulations of any federal, state or international jurisdiction in which we operate could increase our tax burden and otherwise adversely affect our financial position, results of operations, cash flows and liquidity. We continue to assess the impact of various U.S. federal, state, local and international legislative proposals that could result in a material increase to our U.S. federal, state, local 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,

2024 Annual Report 19 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 financial position, results of operations, cash flows and liquidity. • We may be exposed to liabilities under the FCPA and any determination that we or any of our subsidiaries has violated the FCPA could have a material adverse effect on our business. The FCPA generally prohibits companies and their affiliates from making improper payment to non-U.S. officials for the purpose of obtaining or retaining business. Our internal policies, procedures and Code of Conduct mandate compliance with these anti-corruption laws. However, we operate in one or more countries known to experience corruption. Despite our training and compliance programs, we cannot provide assurance that our internal policies and procedures will always protect us from violation of such anti-corruption laws committed by our affiliated entities or their respective officers, directors, employees and agents. We could also face fines, sanctions and other penalties from authorities in the relevant foreign jurisdictions, including prohibition of participating in or curtailment of business operations in those jurisdictions and the seizure of certain of our assets. Our customers in those jurisdictions could also seek to impose penalties or take other actions adverse to our interest. In addition, we could face other third-party claims by, among others, our stockholders, debt holders or other interest holders or constituents. Violations of FCPA laws, allegations of such violations and/or disclosure related to any relevant investigation could have a material adverse impact on our financial position, results of operations, cash flows and liquidity for reasons including, but not limited to, an adverse effect on our reputation, our ability to obtain new business or retain existing business, to attract and retain employees, to access the capital markets and/or could give rise to an event of default under the agreements governing our debt instruments. • We restated our consolidated financial statements for certain prior periods, which affected and may continue to affect our business, results of operations and financial condition. We previously restated unaudited quarterly financial information for the first three quarters of the year ended December 31, 2022 to correct (a) errors related to deferred taxes and the calculation of income tax expense in connection with the sale of our trenchless and pipe rehabilitation services business and (b) other immaterial errors. Additionally, we previously restated certain periods in 2019 and prior to correct misstatements associated with project forecasts in our former Heavy Civil operating group. Taken collectively, such restatements: o had and may continue to have the effect of eroding investor confidence in us and our financial reporting and accounting practices and processes; o negatively impacted and may continue to negatively impact the trading price of our common stock; o required that we incur significant expenses and may require that we incur significant additional expenses relating to any litigation or regulatory examinations, investigations, proceedings, orders or indemnification claims; o may make it more difficult, expensive and time consuming for us to raise capital, if necessary, on acceptable terms, if at all; o may make it more difficult to pursue transactions or implement business strategies that might otherwise be beneficial to our business; and o may negatively impact our reputation with our customers. The occurrence or continued occurrence of any of the foregoing could have a material adverse effect on our business, results of operations and financial condition. • In prior years we identified material weaknesses in our internal control over financial reporting in our Annual Reports on Form 10-K, which have been remediated. If we identify material weaknesses in the future or otherwise fail to maintain an effective system of internal controls, we may not be able to accurately and timely report our financial results, investors may lose confidence in us and the market price of our common stock may decrease. As disclosed in our Annual Reports on Form 10-K for the years ended December 31, 2019, 2020 and 2022, we identified material weaknesses, all of which have now been remediated. We may not be able to accurately and timely report our financial results and/or we may not be able to detect errors on a timely basis if in the future we: (1) identify one or more material weaknesses in our internal control over financial reporting; (2) are unable to successfully remediate any future material weaknesses; (3) are unable to comply with the requirements of Section 404 in a timely manner; or (4) are unable to assert, or our independent registered public accounting firm is unable to attest, that our internal control over financial reporting is effective. This could result in: (i) our financial statements being materially misstated; (ii) investors losing confidence in the accuracy and completeness of our financial reports; (iii) the market price of our common stock decreasing; (iv) our liquidity and access to the capital markets being adversely affected; and (v) our inability to maintain compliance with applicable stock exchange listing requirements and debt covenants. We could also become subject to stockholder or other third-party litigation as well as investigations by the stock exchange on which our securities are listed, the SEC or other regulatory authorities, which could require additional financial and management resources and could result in fines, penalties, trading suspensions or other remedies.

20 Granite Construction Incorporated Further, because of its inherent limitations, even our remediated and effective internal control over financial reporting may not prevent or detect all misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in our conditions, or that the degree of compliance with our policies or procedures may deteriorate. • We were involved in, and may in the future be subject to, litigation, regulatory examinations, investigations, proceedings or orders as a result of or relating to the restatement of our financial statements and if any of these are resolved adversely against us, it could harm our business, results of operations and financial condition. We were involved in, and may in the future be subject to, litigation, regulatory examinations, investigations, proceedings or orders, the assessment of civil monetary penalties, equitable remedies or indemnification claims, and the expenses associated with such matters as a result of or relating to the restatement of our financial statements and reported material weaknesses. Our management may be required to devote significant time and attention to these matters. We had, and may in the future have, to incur significant expenses related to these matters and if any of these matters are resolved adversely against us, it could harm our business, results of operations and financial condition. RISKS RELATED TO INFORMATION TECHNOLOGY • Changes to our outsourced software or infrastructure vendors as well as any sudden loss, breach of security, disruption or unexpected data or vendor loss associated with our information technology systems could have a material adverse effect on our business. We rely on third-party software and infrastructure to run critical accounting, project management and financial information systems. If software or infrastructure vendors decide to discontinue further development, integration or long-term maintenance support for our information systems, or there is any system interruption, delay, breach of security, loss of data or loss of a vendor, we may need to migrate some or all of our accounting, project management and financial information to other systems. These disruptions could increase our operational expense as well as impact the management of our business operations, which could have a material adverse effect on our financial position, results of operations, cash flows and liquidity. • Cybersecurity incidents or breaches of our information technology environment could result in business interruptions, remediation costs and/or legal claims. We have experienced and may continue to face cybersecurity incidents, including ransomware and unauthorized access, aimed at misappropriating information, corrupting data or causing operational disruptions. Additionally, the increased prevalence and use of artificial intelligence may heighten the risk that we may be subject to cybersecurity incidents in the future. If a failure of our cybersecurity defense 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 financial position, results of operations, cash flows and liquidity. • Artificial intelligence presents risks and challenges that could have a material adverse effect on our business, results of operations and financial condition. As of the date of this filing, we have developed pilot programs to implement certain third-party generative artificial intelligence (“AI”) and predictive analytics tools into our systems for specific purposes. These tools presently include, without limitation, (i) a knowledge retention tool, (ii) a risk detection tool and (iii) a virtual assistant tool. There is a risk that such AI tools (or AI tools used without Company approval) will be used in a manner that does not adhere to our AI policy and/or may be misused by our employees, vendors, or other third parties engaged by us. This, in turn, could result in the loss of confidential or proprietary information and subject us to competitive or reputational harm, as well as potential regulatory investigations/actions and/or legal liability. Additionally, we may not be able to control – and may lack visibility into – how third-party AI tools use, or AI features incorporated into third-party products that we use, are developed or maintained, or how such tools use, disclose and/or protect the data we input, even where we have sought contractual protections with respect to these matters. Further, AI algorithms may be flawed, and the data used to train AI tools may be inaccurate, incomplete or biased. As a result, the content, analysis or recommendations that these tools produce may be inaccurate, incomplete or biased and our use of this information may have a material adverse effect on our business, results of operations and financial condition. Similarly, given the emerging ethical issues presented by the development and use of AI tools, we expect that there will continue to be new laws or regulations concerning the use of AI that could impose on us certain obligations and costs related to monitoring and compliance. Finally, we may not be successful in, and may lack sufficient resources to pursue, adopting and implementing AI tools to the same extent as our competitors. If we are unable to adopt and implement these tools in a cost-effective, timely manner or at all, it could cause competitive harm and/or have a material adverse effect on our business, results of operations and financial condition.

2024 Annual Report 21 RISKS RELATED TO OUR CAPITAL STRUCTURE • Failure to remain in compliance with covenants under our Credit Agreement, service our indebtedness, or fund our other liquidity needs could adversely impact our business. Our failure to comply with any of the restrictive or financial covenants would constitute an event of default under our Credit Agreement. Our failure to pay principal, interest or other amounts when due or within the relevant grace period on our 3.25% Convertible Notes, our 3.75% Convertible Notes or our Credit Agreement would constitute an event of default under the indenture governing our 3.25% Convertible Notes, the indenture governing our 3.75% Convertible Notes or the Credit Agreement. A default under our Credit Agreement could result in (i) us no longer being entitled to borrow under such facility; (ii) termination of such facility; (iii) the requirement that any letters of credit under such facility be cash collateralized; (iv) acceleration of amounts owed under the Credit Agreement; and/or (v) foreclosure on any collateral securing the obligations under such facility. A default under the indenture governing our 3.25% Convertible Notes or the indenture governing our 3.75% Convertible Notes could result in acceleration of the maturity of the notes. If we are unable to service our debt obligations as a result of rising or high interest rates or any other reason or fund our other liquidity needs, 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 cause holders of our securities to experience a partial or total loss of their investment in us. See definition of 3.25% Convertible Notes and 3.75% Convertible Notes in Note 14 to “Notes to the Consolidated Financial Statements.” • Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our debt. Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including our 3.25% Convertible Notes and our 3.75% Convertible Notes and the obligations under our Credit Agreement, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Additionally, borrowings under our Credit Agreement bear interest at a variable rate. As interest rates increase or remain high, our interest expense will also increase or remain high if we continue to borrow or increase our borrowings under the credit facility. Our business may not continue to generate sufficient cash flow from operations in the future to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the financial markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. • Conversion of our 3.25% Convertible Notes and our 3.75% Convertible Notes may dilute the ownership interest of existing stockholders and may affect the trading price of our common stock. The 3.25% Convertible Notes and the 3.75% Convertible Notes are convertible at the option of the holders upon the occurrence of certain events and/or during certain periods. Upon conversion of the 3.75% Convertible Notes, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. Upon conversion of the 3.25% Convertible Notes, we will settle the principal amount of the 3.25% Convertible Notes in cash, and any conversion premium in excess of the principal amount in cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. The issuance of shares of our common stock upon conversion of our 3.25% Convertible Notes and our 3.75% Convertible Notes may dilute the ownership interests of existing stockholders. Any sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. • The capped call transactions related to our 3.25% Convertible Notes and our 3.75% Convertible Notes may affect the value of our common stock. In connection with our 3.25% Convertible Notes offering and our 3.75% Convertible Notes offering, we entered into capped call transactions with option counterparties. The capped call transactions are expected generally to reduce the potential dilution to our common stock upon conversion of the 3.25% Convertible Notes and the 3.75% Convertible Notes and/or offset any cash payments we elect or are required to make in excess of the principal amount of converted notes, as the case may be. Further, if the market price per share of our common stock exceeds the cap price of the capped call transactions ($79.83 for the capped call transactions related to the 3.75% Convertible Notes and $119.82 for the capped call transactions related to our 3.25% Convertible Notes), there would nevertheless be dilution and/or there would not be an offset of such cash payments, in each case, to the extent that such market price exceeds the cap price of the capped call transactions. Additionally, in connection with establishing the capped call transactions, the option counterparties may have entered into various derivative transactions with respect to our common stock. The option counterparties may modify their hedge positions by entering into or unwinding various derivatives with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions. This activity could cause or hinder an increase or a decrease in the market price of our common stock. The effect, if any, of these transactions and activities on the market price of our common stock will depend in part on market conditions and cannot be ascertained at this time, but these activities could adversely affect the market price of our common stock.

22 Granite Construction Incorporated • We are subject to counterparty risk with respect to the capped call transactions. The option counterparties are financial institutions or affiliates of financial institutions, and we are subject to the risk that one or more of such option counterparties may default under the capped call transactions. Our exposure to the credit risk of the option counterparties is not secured by any collateral. Past global economic conditions, including recent increases in prevailing interest rates, have resulted in the actual or perceived failure or financial difficulties of many financial institutions. If any option counterparty becomes subject to bankruptcy or other insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under the capped call transaction with such option counterparty. Our exposure will depend on many factors but, generally, an increase in our exposure will be positively correlated to an increase in our common stock market price and in the volatility of the market price of our common stock. In addition, upon a default by an option counterparty, we may suffer adverse tax consequences and dilution with respect to our common stock. We can provide no assurance as to the financial stability or viability of any option counterparty. • The price of our common stock historically has been volatile. Our stock price may continue to be volatile and subject to significant price and volume fluctuations in response to market and other factors, including the other factors discussed in “Risks Factors;” variations in our quarterly operating results from our expectations or those of securities analysts or investors; downward revisions in securities analysts’ estimates; and announcement by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments. In addition, the sale or the availability for sale of a large number of shares of common stock in the public market could cause the price of our common stock to decline. • Delaware law and our charter documents may impede or discourage a takeover, which could reduce potential increases in the market price of our common stock. We are a Delaware corporation, and the anti-takeover provisions of Delaware law impose various impediments to the ability of a third party to acquire control of us, even if a change in control would be beneficial to our existing stockholders. In addition, our Board of Directors has the power, without stockholder approval, to designate the terms of one or more series of preferred stock and issue shares of preferred stock. The ability of our Board of Directors to create and issue a new series of preferred stock and certain provisions of Delaware law and our certificate of incorporation and bylaws could impede a merger, takeover or other business combination involving us or discourage a potential acquirer from making a tender offer for our common stock, which, under certain circumstances, could reduce potential increases in the market price of our common stock. • Our bylaws include a forum selection clause, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us. Unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if and only if the Court of Chancery of the State of Delaware lacks subject matter jurisdiction, any state court located within the State of Delaware or, if and only if all such state courts lack subject matter jurisdiction, the federal district court for the District of Delaware) shall be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (a) any derivative action or proceeding brought on behalf of Granite; (b) any action asserting a breach of a fiduciary duty owed by any director, officer or other employee of Granite to Granite or its stockholders; (c) any action asserting a claim against Granite or any director or officer or other employee of Granite arising pursuant to any provision of the Delaware General Corporation Law, Granite’s certificate of incorporation or bylaws; (d) any action or proceeding to interpret, apply, enforce or determine the validity of Granite’s certificate of incorporation or bylaws (including any right, obligation, or remedy thereunder); (e) any action or proceeding as to which the Delaware General Corporation Law confers jurisdiction to the Court of Chancery of the State of Delaware; or (f) any action asserting a claim against Granite or any director or officer or other employee of Granite that is governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the indispensable parties named as defendants, except that the foregoing does not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Additionally, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, subject to and contingent upon a final adjudication in the State of Delaware of the enforceability of such exclusive forum provision. The forum selection provision in our bylaws may limit our stockholders’ ability to pursue claims in a judicial forum of their choosing for disputes with us, our directors, officers or employees. It is possible that, notwithstanding the forum selection clause included in our bylaws, a court could rule in specific circumstances that such a provision is inapplicable or unenforceable, which could require that we defend claims in other forums. RISKS RELATED TO CLIMATE CHANGE • 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, supply chain 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

2024 Annual Report 23 to our operating results 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 issues. Legislation to regulate greenhouse gas emissions has periodically been introduced and passed by the U.S. Congress and 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 supplies or projects for us and for our clients 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. • We may be unable to achieve our sustainability commitments and targets which could result in the loss of investors and customers, a negative impact to our stock price and damage to our reputation. We are committed to advancing our sustainability strategy. However, achievement of our sustainability commitments and targets is subject to risks and uncertainties, many of which are outside of our control. These risks and uncertainties include, but are not limited to: our ability to execute our operational strategies and achieve our goals within the currently projected costs and the expected timeframes; the availability and cost of alternative fuels and electric vehicles, availability of renewable energy; unforeseen design, operational and technological difficulties; the outcome of research efforts and future technology developments; compliance with, and changes or additions to, global, national, regional and local regulations, taxes, charges, mandates or requirements relating to greenhouse gas emissions, carbon costs or climate-related goals; labor-related regulations and requirements that restrict or prohibit our ability to impose requirements on third party contractors; adapting products to customer preferences and customer acceptance of sustainable supply chain solutions; and the actions of competitors and competitive pressures. There is no assurance that we will be able to successfully implement our strategies and achieve our targets. If we are unable to meet our commitments and targets and appropriately address sustainability enhancement, we may lose investors, customers or partners, our stock price may be negatively impacted, our reputation may be negatively affected and it may be more difficult for us to compete effectively, all of which could have an adverse effect on our business, financial condition and results of operations, as well as on the price of our common stock. In addition, new laws, regulations and policies relating to matters such as sustainability, climate change, human capital and diversity, are being developed and formalized in the United States, which may entail specific, target-driven frameworks and/or disclosure requirements. Any failure, or perceived failure, by us to comply fully with developing interpretations of such laws and regulations could harm our business, reputation, financial condition and results of operations and require significant time and resources to make the necessary adjustments. The foregoing list is not all-inclusive. There can be no assurance that we have correctly identified and appropriately assessed all factors affecting our business or that the publicly available and other information with respect to these matters is complete and correct. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect us. These developments could have material adverse effects on our business, financial condition, results of operations and liquidity. For these reasons, the reader is cautioned not to place undue reliance on our forward-looking statements. Item 1B. Unresolved Staff Comments None.

24 Granite Construction Incorporated Item 1C. Cybersecurity Our Board of Directors views the identification and effective management of cybersecurity threats as a critical component of overall risk management and oversight responsibilities and has delegated responsibility for oversight of this risk to the Audit/Compliance Committee of the Board of Directors (the “Audit Committee”). The Audit Committee oversees the management of risks arising from cybersecurity threats and regularly reports to the Board of Directors regarding cybersecurity. Our Risk Committee of the Board of Directors oversees our enterprise risk management (“ERM”) process, and cybersecurity represents an important component of our overall approach to ERM. Our cybersecurity policies, standards, processes and practices are based on recognized frameworks established by the National Institute of Standards and Technology and other applicable industry standards. In general, we seek to address cybersecurity risks through a comprehensive, cross-functional approach that is focused on identifying, assessing, preventing and mitigating cybersecurity threats and effectively responding to cybersecurity incidents when they occur. Risk Management and Strategy Our cybersecurity program is focused on the following key areas: Governance As discussed in more detail under the heading “Governance” below, the Board of Directors’ oversight of cybersecurity risk management is supported by the Audit Committee, the Risk Committee, our Chief Information Officer (“CIO”), other members of management and management’s Cybersecurity Committee. Technical Safeguards We deploy technical safeguards that are designed to protect our information systems from cybersecurity threats, including firewalls, intrusion prevention and detection systems, anti-malware functionality and access controls, which are evaluated and improved through vulnerability assessments and cybersecurity threat intelligence. Incident Response Planning We have established and maintain an incident response plan that outlines our response in the event of a cybersecurity incident. Third-Party Assessments We periodically assess and test our policies, standards, processes and practices that are designed to address cybersecurity threats and incidents. These efforts include a wide range of activities, including audits, assessments, tabletop exercises, threat modeling, vulnerability testing and other exercises focused on evaluating the effectiveness of our cybersecurity measures and planning. We regularly engage third parties to perform assessments on our cybersecurity measures, including information security maturity assessments, audits and independent reviews of our information security control environment and operating effectiveness. The results of such assessments, audits and reviews are reported to the Audit Committee and, if warranted, the Board of Directors, and we adjust our cybersecurity policies, standards, processes and practices as necessary based on the information provided by these assessments, audits and reviews. Third-Party Risk Management We review and evaluate material cybersecurity risks related to the use of third parties, including vendors, service providers and other external users of our systems. Education and Awareness We provide regular training regarding cybersecurity threats as a means to equip our employees with effective tools to address cybersecurity threats, and to communicate our evolving information security policies, standards, processes and practices. Governance The Audit Committee receives regular presentations and reports from management on cybersecurity risks, which address a wide range of topics including recent developments, evolving standards, vulnerability assessments, third-party and independent reviews, the threat environment, technological trends and information security considerations. The Audit Committee then provides regular reports to the Board of Directors. The Risk Committee also receives timely updates on material and potentially material cybersecurity matters from management as part of the ERM process. The Audit Committee and the Board of Directors also receive timely information regarding any cybersecurity incident that meets established reporting thresholds, as well as ongoing updates regarding any such incident until it has been resolved.

2024 Annual Report 25 The CIO, who acts as our chief information security officer, leads our Cybersecurity Committee. The Cybersecurity Committee is a multidisciplinary team of corporate and operational leaders who work collaboratively to implement a program designed to protect our information systems from cybersecurity threats and to promptly respond to any cybersecurity incidents in accordance with our incident response plan. The Cybersecurity Committee reports to our Chief Executive Officer (“CEO”), Chief Financial Officer (“CFO”), Chief Operating Officer (“COO”), Senior Vice President, Human Resources (“SVP HR”) and Senior Vice President and General Counsel. The CIO, working together with a team of cybersecurity professionals and third-party consultants, monitors the prevention, detection, mitigation and remediation of cybersecurity threats and incidents, and reports such threats and incidents to the senior leadership team when appropriate. Our CIO has served in various roles in information technology and information security for over 25 years, including serving as the Head of Cybersecurity for public and private companies. Our CIO holds an undergraduate degree in computer science and has attained a professional certification in Cybersecurity Governance. The Cybersecurity team (including the CIO) has extensive cybersecurity experience and hold multiple certifications across the cybersecurity landscape. Our CEO, CFO, COO, SVP HR and Senior Vice President and General Counsel each hold undergraduate degrees, graduate degrees or professional certifications in their respective fields, and each have significant experience managing risk. Risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected, and we do not believe are reasonably likely to materially affect, us, including our business strategy, results of operations or financial condition. However, due to evolving cybersecurity threats, it may not be possible to anticipate, prevent or stop future cybersecurity incidents, including attacks on our information systems and data or those of our relevant business partners. See “Risks Related to Information Technology” in Item 1A. Risk Factors. Item 2. Properties Quarry Properties We own or lease quarry properties that contain mineral resources that we extract and process into construction materials. As defined by the SEC, mineral resources are a concentration or occurrence of material of economic interest in or on the earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. As defined by the SEC, mineral reserves are an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of a qualified person, as defined by the SEC, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. Our mineral resources and reserves are based on estimates made by qualified persons who are employees of the Company and are based primarily on geological evidence, sampling and testing and appropriate modifying factors. Amounts presented in the tables below are based on various assumptions to determine estimated economically mineable tons including site specific prices for sand and gravel and hard rock between $5 - $40 per ton. The price per ton estimates use a saleable product (i.e., materials that are ready for sale) as a point of reference and are escalated over time by the Producer’s Price Index for Construction Sand, Gravel and Crushed Stone (product 1321). Pricing for aggregates tend to remain similar for long periods of time; therefore, we use current pricing to estimate prices and we reassess at least annually to verify there have not been material changes. Changes to the estimates and assumptions from those currently anticipated could have a material impact on the mineral resource and mineral reserve estimates. As of December 31, 2024, we had open pit quarry properties available for the extraction of sand, gravel and hard rock. Our Materials segment uses these quarry properties to extract and process sand, gravel and hard rock into construction material for internal use in our construction projects and for sale to third parties. As of December 31, 2024, we had all the permits necessary to mine and process sand, gravel and hard rock at our active quarry properties. As of December 31, 2024, no individual mining operation was considered material to our business or financial condition. Annual production of aggregates for all mining properties was 18.7 million tons, 17.5 million tons, and 16.3 million tons during the years ended December 31, 2024, 2023 and 2022, respectively. The following map shows the approximate locations of our permitted quarry properties as of December 31, 2024:

26 Granite Construction Incorporated California and Utah are the only states/provinces that individually comprise more than 10% of our total mining operations. The following tables present information about our quarry properties as of December 31, 2024 (tons in millions): Resources and Reserves for Each Product Type (tons) Percentage of Resources and Reserves Owned and Leased State/Province Number of Properties Sand & Gravel Hard Rock Owned(1) Leased(2) Acreage California 31 505.4 430.2 63% 37% 10,352 Utah 10 111.9 36.7 67% 33% 1,497 All other states/provinces 62 208.6 259.5 45% 55% 17,349 Total 103 825.9 726.4 58% 42% 29,198 (1) Owned properties are properties we own or in which we have, or it is probable that we will have, a direct or indirect economic interest. (2) Leases are defined as properties where we operate, or it is probable we will operate, under a lease or other legal agreement that grants us ownership or similar rights that authorize us, as principal, to sell or otherwise dispose of the mineral and includes properties that we sublease and from which we receive royalties, which are both considered immaterial. Our leases have terms which range from month-to-month to 50 years with most including an option to renew. The life cycle of mining sand, gravel and hard rock begins with exploration and continues through development and production. After a sand, gravel and hard rock deposit has been identified through exploration, the mine is developed before production begins. The following table presents the number of properties in each respective stage as of December 31, 2024 for all mining properties: State/Province Exploration Development Production California 5 4 22 Utah 1 2 7 All other states/provinces 6 9 47 Total 12 15 76

2024 Annual Report 27 Mineral Resources The table below presents information on measured, indicated and inferred mineral resources. Estimates of measured mineral resources are based on conclusive geological evidence, sampling and testing and may be converted to a proven mineral reserve or to a probable mineral reserve. Estimates of indicated mineral resources are based on adequate geological evidence, sampling and testing and may only be converted to a probable mineral reserve when sufficient evidence is identified including consideration of modifying factors such as mining, processing, economic and environmental factors. Modifying factors are the factors that a qualified person must apply to indicated and measured mineral resources and then evaluate to establish the economic viability of mineral reserves. Estimates of inferred mineral resources have significant geological uncertainty based on limited geological evidence, sampling and testing and therefore may not be converted to a mineral reserve. As of December 31, 2024, our qualified persons estimated our measured, indicated and inferred resources to be approximately 494.9 million tons. As of December 31, 2024, California and Utah were the only individual states/provinces that comprised more than 10% of our total mining operations. The Wine Group, Aerojet North White Rock and Coalinga Section 30 were the only mines that comprised 10% or more of our combined measured and indicated mineral resources for sand and gravel and the Euer Ranch and Bamberton Quarry were the only mines that comprised 10% or more of our combined measured and indicated mineral resources for hard rock. The following table presents information about our mineral resources at December 31, 2024 (tons in millions): Measured Mineral Resources Indicated Mineral Resources Measured + Indicated Mineral Resources Inferred Mineral Resources Amount (tons) Grades/ qualities(1) Amount (tons) Grades/ qualities(1) Amount (tons) Grades/ qualities(1) Amount (tons) Grades/ qualities(1) Sand and Gravel: California The Wine Group — — 51.4 Sand and Gravel 51.4 Sand and Gravel — — Aerojet North White Rock 32.0 Sand and Gravel — — 32.0 Sand and Gravel — — Coalinga Section 30 — — 18.0 Sand and Gravel 18.0 Sand and Gravel — — All other California 15.4 Sand and Gravel 1.6 Sand and Gravel 17.0 Sand and Gravel — — Total California 47.4 — 71.0 — 118.4 — — — All other states/provinces 12.6 Sand and Gravel 8.6 Sand and Gravel 21.2 Sand and Gravel 0.7 Sand and Gravel Total 60.0 — 79.6 — 139.6 — 0.7 — Hard Rock: California Euer Ranch 218.1 Hard Rock — — 218.1 Hard Rock — — All other California 9.9 Hard Rock — — 9.9 Hard Rock — — Total California 228.0 — — — 228.0 — — — Utah 9.6 Hard Rock — — 9.6 Hard Rock — — Bamberton Quarry (Canada) 42.4 Hard Rock 2.3 Hard Rock 44.7 Hard Rock 39.3 Hard Rock All other states/provinces — — — — — — 33.0 Hard Rock Total 280.0 — 2.3 — 282.3 — 72.3 — Grand Total 340.0 — 81.9 — 421.9 — 73.0 — (1) The grade of product produced is contingent on market needs. Sites typically sell base products that range from low to high grades including fill materials, base aggregates, hot mix aggregates and concrete aggregates. Mineral Reserves Mineral reserves are divided into proven and probable mineral reserves. Proven mineral reserves are the economically mineable part of a measured mineral resource and can only result from the conversion of a measured mineral resource. Proven mineral resources are determined by a qualified person through the testing of samples obtained from closely spaced subsurface drilling and/or exposed pit faces, and are sufficiently understood so that quantity, quality and engineering conditions are known with sufficient accuracy to be mined without the need for any further subsurface work. Probable mineral reserves are the economically mineable part of an indicated, and in some cases, a measured mineral resource. Probable mineral reserves are determined through the testing of samples obtained from subsurface drilling, but the sample points are too widely spaced to allow detailed prediction of quantity, quality and engineering conditions. Additional subsurface work may be needed prior to mining the reserve.

28 Granite Construction Incorporated The modifying factors applied in the conversion of measured and indicated mineral resources to proven and probable mineral reserves during the year ended December 31, 2024 included various relevant technical and economic factors, including site infrastructure, mine design and planning, processing plant and environmental compliance and permitting. The basis of determining the modifying factors was a combination of historical experience mining aggregates and observation. As of December 31, 2024, our qualified persons estimated our proven and probable reserves to be approximately 1.1 billion tons. Waste factors for proven and probable reserves range up to 44% depending on the deposit type, market characteristics and extraction feasibility. As of December 31, 2024, California and Utah were the only individual states/provinces that comprised more than 10% of our total mining operations, Coalinga, Solari and Grantsville were the only mines that comprised 10% or more of our mineral reserves for sand and gravel and Handley Quarry, Lockwood Mustang and Bamberton Quarry were the only mines that comprised 10% or more of our mineral reserves for hard rock.

Sites typically sell base products that range from low to high grades including fill materials, base aggregates, hot mix aggregates and concrete aggregates. Internal controls Mining operations include risk in estimation of mineral reserves and mineral resources that could be impacted by unforeseen geologic circumstances, changes in regulation or changes in sales and customers. The risk that these estimates would be unreasonable based on the known information is mitigated by the following internal controls that we use in our exploration and mineral resource and mineral reserve estimation efforts: • quality control and quality assurance programs including management identifying the qualified person(s) with the appropriate background and qualifications to prepare the information used for disclosure purposes;

2024 Annual Report 29 • verification of analytical procedures including management reviewing the mineral resource and reserve report information for completeness, accuracy and appropriateness, such as categorization, inclusion of technical, economic and operational factors, discounted cash flow analysis inputs, assumptions and calculations, and mining, metallurgical, legal, environmental compliance and governmental modifying factors as well as comparison of estimates to historic production and prior period estimates; and • review of disclosures to ensure compliance with requirements. Plant Properties We operate plants at our quarry sites to process aggregates into construction materials. Some of our sites may have more than one crushing, concrete or asphalt processing plant. The following table presents the number of plants we owned and leased as of the respective dates: December 31, 2024 2023 Aggregate crushing plants 40 35 Asphalt concrete plants(1) 59 59 Cement concrete batch plants 10 6 Asphalt rubber plants 4 4 Lime slurry plants 6 6 (1) Three of our asphalt concrete plants were operated under lease agreements for the years ended December 31, 2024 and 2023. These plants are used by both of our reportable segments. Item 3.

32 Granite Construction Incorporated Item 6. Reserved Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations General We deliver infrastructure solutions for public and private clients primarily in the United States. We are one of the largest diversified, vertically integrated civil contractors and construction materials producers in the United States. Within the public sector, we primarily concentrate on infrastructure projects, including the construction of streets, roads, highways, mass transit facilities, airport infrastructure, bridges, dams, power-related facilities, utilities, tunnels, water well drilling and other infrastructure-related projects. Within the private sector, we perform various services such as site preparation, mining services and infrastructure services for commercial and industrial sites, railways, residential development, energy development, as well as provide construction management professional services. We own and lease aggregate reserves and own processing plants that are vertically integrated into our construction operations and we also produce construction materials for sale to third parties. We have vertically integrated operations across Alaska, Arizona, California, Mississippi, Nevada, Oregon, Tennessee, Utah and Washington in addition to regional civil construction home markets in Illinois, Florida and Texas. Our Construction segment also operates national businesses within the Tunnel division, the Rail division, the Federal division, which performs civil construction across the continental United States and Guam, the Industrial & Energy division, which primarily focuses on commercial solar construction projects, and the Layne division, which performs water well drilling, rehabilitation services and mineral exploration services. Our reportable segments are the same as our operating segments and correspond with how our chief operating decision maker, or decision-making group (our “CODM”), regularly reviews financial information to allocate resources and assess performance. We identified our CODM as our Chief Executive Officer and our Chief Operating Officer. Our reportable segments are: Construction and Materials. The Construction segment focuses on construction and rehabilitation of roads, pavement preservation, bridges, rail lines, airports, marine ports, dams, reservoirs, aqueducts, infrastructure and site development for use by the general public and water-related construction for municipal agencies, commercial water suppliers, industrial facilities and energy companies. It also provides construction of various complex projects including infrastructure / site development, mining, public safety, tunnel, solar, battery storage and other power-related projects. The Materials segment focuses on production of aggregates, asphalt concrete, liquid asphalt and recycled materials production for internal use in our construction projects and for sale to third parties. See Note 21 of “Notes to the Consolidated Financial Statements” for additional information about our reportable segments. During the first quarter of 2024, we reorganized our operational structure to more closely align with our two reportable segments, Construction and Materials. Previously, leaders within our three former operating groups of California, Central and Mountain managed both Construction and Materials operations within each group. This change allows us to better leverage our expertise within each reportable segment with leadership having direct oversight of their respective segment operations. As a result of the reorganization, we will no longer disclose financial information by operating group. There were no material impacts to our consolidated financial statements and no changes to our reportable segments. The five primary economic drivers of our business are (i) the overall health of the U.S. economy including access to resources (labor, supplies and subcontractors); (ii) federal, state and local public funding levels; (iii) population growth resulting in public and private development; (iv) the need to build, replace or repair aging infrastructure; and (v) the pricing of certain commodity related products. A stagnant or declining economy will generally result in reduced demand for construction and construction materials in the private sector. This reduced demand increases competition for private sector projects and will ultimately also increase competition in the public sector as companies migrate from bidding on scarce private sector work to projects in the public sector. In addition, a stagnant or declining economy tends to produce less tax revenue for public agencies, thereby decreasing a source of funds available for spending on public infrastructure improvements. Some funding sources that have been specifically earmarked for infrastructure spending, such as diesel and gasoline taxes, are not as directly affected by a stagnant or declining economy, unless actual consumption is reduced or gasoline sales tax revenues decline consistent with fuel prices. However, even these can be temporarily at risk as federal, state and local governments take actions to balance their budgets. Conversely, increased levels of public funding as well as an expanding or robust economy will generally increase demand for our services and products and provide opportunities for revenue growth and margin improvement.

2024 Annual Report 33 Critical Accounting Estimate The financial statements included in “Item 8. Financial Statements and Supplementary Data” have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of these financial statements requires management to make estimates that affect the reported amounts of assets and liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Our estimates and related judgments and assumptions are continually evaluated based on available information and experiences; however, actual amounts could differ from those estimates. We consider revenue recognition a critical accounting estimate. It involves significant management judgment and can significantly affect our reported results of operations. Revenue Recognition Our revenue is primarily derived from construction contracts that can span several quarters or years in our Construction segment and from sales of construction related materials in our Materials segment. We recognize revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, and subsequently issued additional related ASUs. The accuracy of our revenue and profit recognition in a given period depends on the accuracy of our estimates of the forecasted revenue and cost to complete each project. Cost estimates for all of our significant projects use a detailed “bottom up” approach. There are a number of factors that can contribute to changes in estimates of contract cost and profitability. The most significant of these include: • changes in costs of labor and/or materials; • subcontractor costs, availability and/or performance issues; • extended overhead and other costs due to owner, weather and other delays; • changes in productivity expectations; • changes from original design on design-build projects; • our ability to fully and promptly recover on affirmative claims and back charges for additional contract costs; • a change in the availability and proximity of equipment and materials; • complexity in original design; • length of time to complete the project; • the availability and skill level of workers in the geographic location of the project; • site conditions that differ from those assumed in the original bid; • costs associated with scope changes; and • the customer’s ability to properly administer the contract. The foregoing factors, as well as the stage of completion of contracts in process and the mix of contracts at different margins may cause fluctuations in gross profit and gross profit margin from period to period. Significant changes in revenue and cost estimates, particularly in our larger, more complex, multi-year projects have had, and in the future could have, a significant effect on our profitability. Due to the number of factors that can contribute to changes in estimates of contract cost and profitability, the sensitivity of reported amounts to the assumptions underlying the estimate’s calculation is not reasonably available or meaningful. However, Note 3 of “Notes to the Consolidated Financial Statements” presents the impact material revisions in estimates had on the periods covered by this report. Current Economic Environment and Outlook Funding for our public work projects, which account for approximately 80% of our portfolio, is dependent on federal, state, regional and local revenues. At the federal level, the continued rollout of the $1.2 trillion Infrastructure Investment and Jobs Act (“IIJA”) has increased federal highway, bridge and transit funding to its highest level in more than six decades with $550 billion in incremental funding over five years. The increased multi-year spending commitment has improved the programming visibility for state and local governments and has driven an increase in project lettings that started in 2023, continued in 2024 and we believe will carry into 2025 and beyond. At state, regional and local levels, voter-approved state and local transportation measures continue to support infrastructure spending. While each market is unique, we see a strong funding environment at the state and local levels aided by the IIJA. In California, our top revenue-generating state, despite overall budgetary concerns, a significant part of the state infrastructure spend is funded through Senate Bill 1 (SB-1), the Road Repair and Accountability Act of 2017, a 10-year, $54.2 billion program, which may only be used for transportation-related purposes, without any sunset provisions.

34 Granite Construction Incorporated Over the last several years, inflation, supply chain and labor constraints have had a significant impact on the global economy including the construction industry in the United States. While it is impossible to fully eliminate the impact of these factors, where practicable, we have applied proactive measures such as fixed forward purchase contracts of oil related inputs, energy surcharges, and adjustment of project schedules for constraints related to construction materials such as concrete. While we actively work to mitigate the impacts of oil price inflation, further price increases may adversely impact us in the future. Our Committed and Awarded Projects (“CAP”) balance continues to be strong at $5.3 billion at the end of the fourth quarter of 2024. Our CAP is supported by a positive public funding environment and resilient private market which we believe will provide further opportunities for continued CAP growth in 2025. Acquisitions On August 9, 2024, we acquired Dickerson & Bowen, Inc. (“D&B”). D&B is an aggregates, asphalt, and highway construction company serving central and southern Mississippi. On November 30, 2023, we acquired Lehman-Roberts Company and Memphis Stone & Gravel Company (collectively, “LRC/MSG”). LRC/MSG operates strategically located asphalt plants and sand and gravel mines serving the greater Memphis area and northern Mississippi. On April 24, 2023, we acquired Coast Mountain Resources (2020) Ltd. which changed its name to Granite Infrastructure Canada, Ltd. (“Granite Canada”) on May 13, 2024. Granite Canada is a construction aggregate producer based in British Columbia, Canada operating on Malahat First Nation land. The results of operations of these businesses are included in our consolidated financial statements from the dates of acquisition which impacts comparability to the applicable prior periods. See Note 1 and Note 2 of “Notes to the Consolidated Financial Statements” for further information. Results of Operations Our operations are typically affected more by inclement weather conditions during the first and fourth quarters of our fiscal year which may alter our construction schedules and can create variability in our revenues and profitability.

2024 Annual Report 35 CONSTRUCTION REVENUE Years Ended December 31, 2024 2023 2022 (dollars in thousands) Public $ 2,531,379 74.1% $ 2,064,078 69.0% $ 1,891,338 67.5% Private 883,846 25.9 928,176 31.0 912,597 32.5 Total $ 3,415,225 100.0% $ 2,992,254 100.0% $ 2,803,935 100.0% Construction revenue in 2024 increased by $423.0 million, or 14.1%, compared to 2023, primarily due to a higher level of CAP to start the year, more favorable weather conditions early in 2024 and increased revenue from acquired businesses of $114.7 million due to the timing of the acquisition of LRC/MSG in 2023 and the acquisition of D&B in 2024. MATERIALS REVENUE Materials revenue in 2024 increased by $75.5 million, or 14.6%, when compared to 2023, driven primarily by increases in revenue from newly acquired businesses of $66.9 million, in addition to higher asphalt and aggregate sales prices. Committed and Awarded Projects CAP consists of two components: (1) unearned revenue and (2) other awards. Unearned revenue includes the revenue we expect to record in the future on executed contracts, including 100% of our consolidated joint venture contracts and our proportionate share of unconsolidated joint venture contracts. We generally include a project in unearned revenue at the time a contract is awarded, the contract has been executed and to the extent we believe funding is probable. Contract options and task orders are included in unearned revenue when exercised or issued, respectively. Certain government contracts where funding is appropriated on a periodic basis are included in unearned revenue at the time of the award when it is probable the contract value will be funded and executed. Other awards include the general construction portion of construction management/general contractor (“CM/GC”) contracts and awarded contracts with unexercised contract options or unissued task orders. The general construction portion of CM/GC contracts are included in other awards to the extent contract execution and funding is probable. Contracts with unexercised contract options or unissued task orders are included in other awards to the extent option exercise or task order issuance is probable. All CAP is in the Construction segment. December 31, 2024 2023 (dollars in thousands) Unearned revenue $ 3,584,378 67.7% $ 3,596,676 64.9% Other awards 1,711,689 32.3 1,949,078 35.1 Total $ 5,296,067 100.0% $ 5,545,754 100.0% December 31, 2024 2023 (dollars in thousands) Public $ 4,120,821 77.8% $ 4,368,904 78.8% Private 1,175,246 22.2 1,176,850 21.2 Total $ 5,296,067 100.0% $ 5,545,754 100.0% CAP of $5.3 billion at December 31, 2024 was $0.2 billion, or 5% lower than December 31, 2023 due to higher revenue in 2024 and lower additions to CAP in 2024. Bidding activity remained robust in 2024, and several significant project awards are expected to be added to CAP during the first half of 2025. The most significant additions to CAP during 2024 included $196 million for six highway projects in California, $180 million for a pumping station project in Nevada, $158 million of Federal work in Guam and $114 million for a bridge project in Michigan. Non-controlling partners’ share of CAP as of December 31, 2024 and 2023 was $331.1 million and $243.8 million, respectively. At December 31, 2024 and 2023, one and six contracts with remaining CAP of $10.0 million or more per project had total forecasted losses with remaining revenue of $64.4 million, or 1.2% of total CAP, and $188.9 million, or 3.4% of total CAP, respectively. Provisions are recognized in the consolidated statements of operations for the full amount of estimated losses on uncompleted contracts whenever evidence indicates that the estimated total cost of a contract exceeds its estimated total revenue.

36 Granite Construction Incorporated Gross Profit The following table presents gross profit by reportable segment for the respective periods: Years Ended December 31, 2024 2023 2022 (dollars in thousands) Construction $ 491,002 $325,055 $303,881 Percent of segment revenue 14.4% 10.9% 10.8% Materials 81,695 71,344 65,613 Percent of segment revenue 13.8 13.8 13.2 Total gross profit $ 572,697 $396,399 $369,494 Percent of total revenue 14.3% 11.3% 11.2% Construction gross profit for the year ended December 31, 2024 increased by $165.9 million, or 51.1%, when compared to 2023, primarily due to higher revenue and improved project execution across our project portfolio resulting in net increases from revisions in estimates in the current period compared to net decreases in the prior period. For further discussion of projects with revisions in estimates which individually had an impact of $5.0 million or more on gross profit, see Note 3 of “Notes to the Consolidated Financial Statements.” Additionally, gross profit from acquired businesses increased by $11.5 million for the year ended December 31, 2024, including $8.1 million of purchase accounting related depreciation and intangible asset amortization. Materials gross profit for the year ended December 31, 2024 increased by $10.4 million, or 14.5%, when compared to 2023 and gross profit margin remained consistent at 13.8%. The improvement in gross profit was primarily due to the results of acquired businesses as well as higher revenue. Materials gross profit from acquired businesses increased by $7.8 million for the year ended December 31, 2024, including $4.1 million of purchase accounting related depreciation and intangible asset amortization. Selling, General and Administrative Expenses The following table presents the components of selling, general and administrative expenses for the respective periods: Years Ended December 31, 2024 2023 2022 (dollars in thousands) Salaries and related expenses $ 171,835 $ 157,239 $ 161,082 Incentive compensation 32,094 29,364 16,424 Stock-based compensation 17,826 9,753 6,361 Other selling, general and administrative expenses 112,407 98,110 88,743 Total selling, general and administrative expenses $ 334,162 $ 294,466 $ 272,610 Percent of revenue 8.3% 8.4% 8.3% Selling, general and administrative (“SG&A”) expenses include the costs for estimating and bidding, including offsetting customer reimbursements for portions of our selling/bid submission expenses (i.e., stipends), business development, materials facility permits, and costs related to our operational offices that are not allocated to direct contract costs and expenses related to our corporate functions. Other SG&A expenses include travel and entertainment, outside services, information technology, depreciation, occupancy, training, office supplies, changes in the fair market value of our Non-Qualified Deferred Compensation plan liability and other miscellaneous expenses. SG&A expenses can vary depending on the volume of projects in process and the number of employees assigned to estimating and bidding activities. As projects are completed or the volume of work slows down, we temporarily redeploy project employees to bid on new projects, moving their salaries and related costs from cost of revenue to selling expenses. SG&A expenses for 2024 increased $39.7 million compared to 2023, primarily due to a $17.0 million increase in SG&A expenses from acquired businesses, including $6.3 million of purchase accounting related depreciation and intangible asset amortization. The remaining increase was due to higher stock-based compensation and incentive compensation due to improved financial performance, as well as higher salaries and related expenses due to increased labor costs. Other Costs, net The following table presents other costs, net for the respective periods: Years Ended December 31, 2024 2023 2022 (in thousands) Other costs, net $ 39,936 $ 50,217 $ 24,120

2024 Annual Report 37 Other costs for the year ended December 31, 2024 decreased by $10.3 million when compared to 2023 primarily due to a $20.0 million litigation charge in the prior year that did not recur in the current year, partially offset by an increase in costs in the current year associated with the defense of a former Company officer in his ongoing civil litigation with the Securities and Exchange Commission. Gain on Sales of Property and Equipment, net The following table presents the gain on sales of property and equipment, net for the respective periods: Years Ended December 31, 2024 2023 2022 (in thousands) Gain on sales of property and equipment, net $ (8,764) $ (28,346) $ (12,617) Gain on sales of property and equipment, net for the year ended December 31, 2024 decreased by $19.6 million when compared to 2023 primarily due to the sale of a property in Texas in 2023. Other (Income) Expense The following table presents the components of other (income) expense, net for the respective periods: Years Ended December 31, 2024 2023 2022 (in thousands) Loss on debt extinguishment $ 27,552 $ 51,052 $ — Interest income (24,349) (17,538) (6,528) Interest expense 29,188 18,462 12,624 Equity in income of affiliates, net (16,982) (25,748) (13,571) Other (income) expense, net (4,238) (6,020) 1,039 Total other (income) expense, net $ 11,171 $ 20,208 $ (6,436) During 2024, we repurchased approximately $30.2 million in aggregate principal amount of our 2.75% Convertible Notes and incurred a $27.6 million loss on debt extinguishment, which was $23.5 million less than the 2023 extinguishment charge. During 2024, interest expense, net of interest income, increased $3.9 million, as a result of increased borrowings, partially offset by higher interest income due to higher cash balances. Equity in income of affiliates, net decreased by $8.8 million when compared to 2023 primarily due to lower net income of our affiliates. Income Taxes The following table presents the provision for income taxes for the respective periods: Years Ended December 31, 2024 2023 2022 (in thousands) Provision for income taxes $ 55,749 $ 30,267 $ 12,960 Effective tax rate 28.4% 50.6% 14.1% Our effective tax rate decreased from 50.6% to 28.4% when compared to 2023 primarily due to a decrease in nondeductible debt extinguishment costs along with a favorable adjustment for non-controlling interest in the current year. Amount Attributable to Non-controlling Interests The following table presents the amount attributable to non-controlling interests in consolidated subsidiaries for the respective periods: Years Ended December 31, 2024 2023 2022 (in thousands) Amount attributable to non-controlling interests $ (14,097) $ 14,012 $ 4,445 The amount attributable to non-controlling interests represents the non-controlling owners’ share of the net (income) loss of our consolidated construction joint ventures. The increase during 2024 was primarily due to the impact of less negative revisions in estimates related to consolidated construction joint ventures (see Note 3 of “Notes to the Consolidated Financial Statements”).

38 Granite Construction Incorporated Prior Years Comparison (2023 to 2022) See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2023 Annual Report on Form 10-K filed with the SEC on February 23, 2024. Liquidity and Capital Resources Our primary sources of liquidity are cash and cash equivalents, investments, available borrowing capacity under our credit facility and cash generated from operations. We may also from time to time issue and sell equity, debt or hybrid securities or engage in other capital markets transactions or sell one or more business units or assets. See Note 14 of the “Notes to the Consolidated Financial Statements” for information on our long-term debt. Our material cash requirements include paying the costs and expenses associated with our operations, servicing outstanding indebtedness, making capital expenditures and paying dividends on our capital stock. We may also from time to time prepay or repurchase outstanding indebtedness, repurchase shares of our common stock or acquire assets or businesses that are complementary to our operations. See Note 2 and Note 17 of the “Notes to the Consolidated Financial Statements” for information on our acquisitions and share repurchases, respectively. Our primary contractual obligations are as follows and are further discussed in the referenced “Notes to the Consolidated Financial Statements:” • Asset retirement obligations - see Note 11, Property and Equipment, net • Long-term debt and the associated interest payments – see Note 14, Long-Term Debt • Operating lease and royalty future minimum payments – see Note 15, Leases • Non-Qualified Deferred Compensation Plan obligations – see Note 16, Employee Benefit Plans In addition to the obligations referenced above, as of December 31, 2024 we had $16.4 million of purchase commitments for equipment and other goods and services not directly connected with our construction contracts, which are individually greater than $50,000 and have an expected fulfillment date after December 31, 2024. Of this, approximately $15.0 million, $1.0 million and $0.4 million will be paid in 2025, 2026 and 2027, respectively. There are no material purchase commitments in the periods thereafter. We believe our primary sources of liquidity will be sufficient to meet our expected working capital needs, capital expenditures, financial commitments, cash dividend payments and other liquidity requirements associated with our existing operations for the next twelve months. We also believe our primary sources of liquidity, access to debt and equity capital markets and cash expected to be generated from operations will be sufficient to meet our long-term requirements and plans. However, there can be no assurance that sufficient capital will continue to be available or that it will be available on terms acceptable to us. Cash, cash equivalents and marketable securities as of December 31, 2024 increased $132.1 million to $585.6 million from the prior year end. In addition to meeting our liquidity requirements listed above, our increased cash balances are expected to be used to invest in our business through strategic capital expenditures in 2025 and we will continue to explore acquisition opportunities in alignment with our strategic plan. As of December 31, 2024, our cash and cash equivalents consisted of deposits and money market funds held with established national financial institutions and marketable securities consisting primarily of U.S. Government and agency obligations. As of December 31, 2024, the total unused availability under our Credit Agreement was $333.7 million, resulting from $16.3 million in issued and outstanding letters of credit and nothing drawn on the Revolver. See Note 14 of “Notes to the Consolidated Financial Statements.” As of December 31, 2024, we had $1.3 million of receivables and $29.2 million of contract retention receivables from Brightline Trains Florida LLC (“Brightline”) (see Note 6 of “Notes to the Consolidated Financial Statements”), all of which has been collected as of the date of this report.

2024 Annual Report 39 In evaluating our liquidity position and needs, we also consider cash and cash equivalents held by our consolidated construction joint ventures (“CCJVs”). The following table presents our cash, cash equivalents and marketable securities, including amounts from our CCJVs, as of the respective dates: December 31, 2024 2023 (in thousands) Cash and cash equivalents excluding CCJVs $404,436 $297,439 CCJV cash and cash equivalents(1) 173,894 120,224 Total consolidated cash and cash equivalents 578,330 417,663 Short-term marketable securities(2) 7,311 35,863 Total cash, cash equivalents and marketable securities $ 585,641 $ 453,526 (1) The volume and stage of completion of contracts from our CCJVs may cause fluctuations in joint venture cash and cash equivalents between periods. The assets of each consolidated and unconsolidated construction joint venture relate solely to that joint venture. The decision to distribute joint venture assets must generally be made jointly by a majority of the members and, accordingly, these assets, including those associated with estimated cost recovery of customer affirmative claims and back charge claims, are generally not available for the working capital needs of Granite until distributed. (2) All marketable securities were classified as held-to-maturity and consisted of U.S. Government and agency obligations as of all periods presented. Granite’s portion of CCJV cash and cash equivalents was $106.0 million and $73.1 million as of December 31, 2024 and 2023, respectively. Excluded from the table above is $28.7 million and $34.2 million as of December 31, 2024 and 2023, respectively, of Granite’s portion of unconsolidated construction joint venture cash and cash equivalents. Capital Expenditures Major capital expenditures are typically for aggregate and asphalt production facilities, aggregate reserves, construction equipment, buildings and leasehold improvements and investments in our information technology systems. The timing and amount of such expenditures can vary based on the progress of planned capital projects, the type and size of construction projects, changes in business outlook and other factors. During the year ended December 31, 2024, we had capital expenditures of $136.4 million, compared to $140.4 million during 2023, a decrease of $4.0 million. We currently anticipate 2025 capital expenditures to be between approximately $140 million and $160 million, including approximately $50 million in planned strategic materials investments. Cash Flows Years Ended December 31, 2024 2023 2022 (in thousands) Net cash provided by (used in): Operating activities $ 456,343 $ 183,707 $ 55,647 Investing activities $ (228,556) $ (359,290) $ (11,000) Financing activities $ (67,120) $ 299,255 $(164,311) Operating activities As a large infrastructure contractor and construction materials producer, our revenue, gross profit and the resulting operating cash flows can differ significantly from period to period due to a variety of factors, including project progression toward completion, outstanding contract change orders and affirmative claims, and the payment terms of our contracts. Additionally, operating cash flows are impacted by the timing related to funding construction joint ventures and the resolution of uncertainties inherent in the complex nature of the construction work we perform, including claim and back charge settlements. Our working capital assets result from both public and private sector projects. Customers in the private sector can be slower paying than those in the public sector; however, private sector projects generally have higher gross profit as a percentage of revenue. While we typically invoice our customers on a monthly basis, our construction contracts frequently provide for retention that is a specified percentage withheld from each payment by our customers until the contract is completed and the work accepted by the customer. Cash provided by operating activities of $456.3 million during 2024 represents a $272.6 million increase in cash provided by operating activities when compared to 2023. The change was primarily attributable to a $132.8 million increase in net income after adjusting for non-cash items and a $121.7 million increase in cash provided by working capital, which includes receivables, net contract assets, inventories, other assets, accounts payable and accrued expenses and other liabilities. Additionally, distributions from, net of contributions to, unconsolidated construction joint ventures and affiliates increased $18.1 million from 2023.

40 Granite Construction Incorporated Investing activities Cash used in investing activities of $228.6 million during 2024 represents a $130.7 million decrease in cash used in investing activities when compared to 2023. The change was primarily due to a $159.7 million decrease in cash used related to business acquisitions (see Note 3 of “Notes to the Consolidated Financial Statements”), partially offset by a $24.3 million decrease in proceeds from sales of property and equipment. Financing activities Cash used in financing activities of $67.1 million during 2024 represents a $366.4 million increase in cash used in financing activities when compared to 2023. The change was primarily due to a $290.3 million decrease in proceeds from debt issuances, net of debt repayments and related charges. See Note 14 to “Notes to the Consolidated Financial Statements” for further information about our long-term debt transactions and our credit facility. The year over year increase in cash used in financing activities was also due to $46.5 million increase in repurchases of common stock as well as a decrease in contributions from non- controlling partners, net of distributions, of $30.7 million. Derivatives We recognize derivative instruments as either assets or liabilities in the consolidated balance sheets at fair value using Level 2 inputs. See Note 8 to “Notes to the Consolidated Financial Statements” for further information. The capped call transactions related to the 3.75% Convertible Notes and 3.25% Convertible Notes were recorded to equity on our consolidated balance sheets based on the cash proceeds. See Note 14 to “Notes to the Consolidated Financial Statements” for further information. Surety Bonds and Real Estate Mortgages We are generally required to provide various types of surety bonds that provide an additional measure of security under certain public and private sector contracts. At December 31, 2024, approximately $3.2 billion of our $5.3 billion CAP was bonded. Performance bonds do not have stated expiration dates; rather, we are generally released from the bonds when the obligations of the underlying contract have been fulfilled. The ability to maintain bonding capacity requires that we maintain cash and working capital balances satisfactory to our sureties. Our investments in real estate ventures are subject to mortgage indebtedness. This indebtedness is non-recourse to Granite but is recourse to the real estate venture. The terms of this indebtedness are typically renegotiated to reflect the evolving nature of the real estate projects as they progress through acquisition, entitlement, development and leasing. Modification of these terms may include changes in loan-to-value ratios requiring the real estate venture to repay portions of the debt. Our unconsolidated investments in our foreign affiliates are subject to local bank debt primarily for equipment purchases and working capital. This debt is non-recourse to Granite, but it is recourse to the affiliates. The debt associated with our unconsolidated non-construction entities is included in Note 9 of “Notes to the Consolidated Financial Statements.” Covenants and Events of Default Our Credit Agreement requires us to comply with various affirmative, restrictive and financial covenants, including the financial covenants described below. Our failure to comply with these covenants would constitute an event of default under the Credit Agreement. Additionally, the 3.25% Convertible Notes and 3.75% Convertible Notes are governed by the terms and conditions of their respective indentures. Our failure to pay principal, interest or other amounts when due or within the relevant grace period on our 3.25% Convertible Notes, our 3.75% Convertible Notes or our Credit Agreement would constitute an event of default under the 3.25% Convertible Notes indenture, the 3.75% Convertible Notes indenture or the Credit Agreement. A default under our Credit Agreement could result in (i) us no longer being entitled to borrow under such facility; (ii) termination of such facility; (iii) the requirement that any letters of credit under such facility be cash collateralized; (iv) acceleration of amounts owed under the Credit Agreement; and/or (v) foreclosure on any collateral securing the obligations under such facility. A default under the 3.25% Convertible Notes indenture or the 3.75% Convertible Notes indenture could result in acceleration of the maturity of the notes. The most significant financial covenants under the terms of our Credit Agreement require the maintenance of a minimum Consolidated Interest Coverage Ratio and a maximum Consolidated Leverage Ratio. As of December 31, 2024, we were in compliance with the covenants in the Credit Agreement.

2024 Annual Report 41 Share Repurchase Program As announced on February 3, 2022, on February 1, 2022, the Board of Directors authorized us to purchase up to $300.0 million of our common stock at management’s discretion (the “2022 authorization”). During the year ended December 31, 2024, we repurchased 524,800 shares under the 2022 authorization and $189.5 million remained available under the 2022 authorization as of December 31, 2024. The specific timing and amount of any future repurchases will vary based on market conditions, securities law limitations and other factors. Recently Issued and Adopted Accounting Pronouncements See Note 1 of “Notes to the Consolidated Financial Statements” under the caption Recently Issued and Adopted Accounting Pronouncements. Item 7A. Quantitative and Qualitative Disclosures About Market Risk We maintain an investment portfolio of various holdings, types and maturities. We purchase instruments that meet high credit quality standards, as specified in our investment policy. Our investment policy also limits the amount of credit exposure to any one issue, issuer or type of instrument. The portfolio and accompanying cash balances are targeted to an average maturity of no more than one year from the date the purchase is settled. On an ongoing basis we monitor credit ratings, financial condition and other factors that could affect the carrying amount of our investment portfolio. Marketable securities, consisting of U.S. government and agency obligations, are classified as held-to-maturity and are stated at cost, adjusted for amortization of premiums and discounts to maturity. Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents, marketable securities, and accounts receivable. We maintain our cash and cash equivalents and our marketable securities with several financial institutions. Given the short-term nature of certain investments, the related income is subject to the general level of interest rates in the United States at the time of maturity and reinvestment. We manage investment interest rate market risk primarily by managing portfolio maturity. Operating in international markets involves exposure to possible volatile movements in currency exchange rates. Our Materials Segment has an insignificant amount of operations in Canada and we also have affiliates that operate in Latin America (see Note 10 of “Notes to the Consolidated Financial Statements” for further information on our affiliates). As of December 31, 2024, we do not have any outstanding foreign currency option contracts. If the volume of our international operations increases and foreign currency exchange rates change, the impact to our consolidated statements of operations could be significant and may affect year-to-year comparability of operating results. The impact from foreign currency transactions during 2024, 2023 and 2022 was immaterial. We may borrow on the Revolver, at our option, at either (a) the SOFR term rate plus a credit adjustment spread plus applicable margin ranging from 1.0% to 2.0%, or (b) a base rate plus an applicable margin ranging from 0.0% to 1.0%. The applicable margin is based on our Consolidated Leverage Ratio (as defined in our Credit Agreement), calculated quarterly. As of December 31, 2024, there was nothing drawn on the Revolver. See Note 14 of “Notes to the Consolidated Financial Statements” for further discussion on the 3.25% Convertible Notes, 3.75% Convertible Notes and Credit Agreement.

Management’s Report on Internal Control Over Financial Reporting Our management, including our principal executive and principal financial officers, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rules 13a-15(f) and 15d -15(f). Internal control over financial reporting is defined as a process designed by, or under the supervision of, the issuer’s principal executive and principal financial officers, or persons performing similar functions, and effected by the issuer’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that: (1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the issuer; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the issuer are being made only in accordance with authorizations of management and directors of the issuer; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the issuer’s assets that could have a material effect on the financial statements. Our management, under the supervision and with the participation of our principal executive and principal financial officers, has conducted an evaluation of the effectiveness of our internal control over financial reporting, using the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2024. PricewaterhouseCoopers LLP, our independent registered public accounting firm, has audited the effectiveness of our internal control over financial reporting as of December 31, 2024. Their report is included in Part IV, Item 15(a) of this Form 10-K under the heading “Report of Independent Registered Public Accounting Firm.” Changes in Internal Control Over Financial Reporting There were no changes in our internal control over financial reporting during the quarter ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

2024 Annual Report F-1 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Shareholders of Granite Construction Incorporated Opinions on the Financial Statements and Internal Control over Financial Reporting We have audited the accompanying consolidated balance sheets of Granite Construction Incorporated and its subsidiaries (the “Company”) as of December 31, 2024 and 2023, and the related consolidated statements of operations, of comprehensive income (loss), of shareholders’ equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control— Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control—Integrated Framework (2013) issued by the COSO. Basis for Opinions The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

F-2 Granite Construction Incorporated Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Revenue Recognition—Estimates of the Forecasted Revenue and Costs to Complete for Multi-Year Fixed Price Contracts in the Construction Segment As described in Notes 1, 3, and 4 to the consolidated financial statements, the revenue for the construction segment for the year ended December 31, 2024 was $3.415 billion, a portion of which related to multi-year fixed price contracts. Revenue in the Construction segment is ordinarily recognized over time as control is transferred to the customers by measuring the progress toward complete satisfaction of the performance obligation(s) using an input (i.e., cost to cost) method. Under the cost to cost method, costs incurred to date are generally the best depiction of transfer of control. The accuracy of the Company’s revenue and profit recognition in a given period depends on the accuracy of management’s estimates of the forecasted revenue and cost to complete each project. Cost estimates for all significant projects use a detailed bottom up approach in which there are a number of factors that can contribute to revisions in estimates of contract cost and profitability. Provisions for losses are recognized at the uncompleted performance obligation level for the amount of total estimated losses in the period that evidence indicates that the estimated total cost of a performance obligation exceeds its estimated total revenue. The estimates of transaction price and costs to complete can vary significantly in the normal course of business as projects progress, circumstances develop and evolve, and uncertainties are resolved. When the Company experiences significant revisions in estimates, management undergoes a process that includes reviewing the nature of the changes to ensure that no material amounts should have been recorded in a prior period rather than as a revision in estimate for the current period. Management generally uses the cumulative catch-up method for changes to the transaction price that are part of a single performance obligation. Under this method, revisions in estimates are accounted for in their entirety in the period of change. The principal considerations for our determination that performing procedures relating to estimates of the forecasted revenue and costs to complete for multi-year fixed price contracts in the Construction segment is a critical audit matter are (i) the significant judgment by management when determining the estimates of forecasted revenue and costs to complete, and revisions in those estimates and (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence related to management’s estimates of forecasted revenue and costs to complete for multi-year fixed price contracts in the Construction segment, and revisions in those estimates. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process, including controls over management’s estimates of forecasted revenue and costs to complete for multi-year fixed price contracts in the Construction segment, and revisions in those estimates. These procedures also included, among others, for a sample of multi-year fixed price contracts, testing management’s process for determining the estimates of forecasted revenue and costs to complete, which included (i) assessing management’s ability to reasonably estimate the forecasted revenue and costs to complete by evaluating management’s methodology and assessing the consistency of management’s approach over the life of the contract and (ii) evaluating the timely identification of circumstances that may warrant a modification to estimated forecasted revenue and costs to complete. /s/ PricewaterhouseCoopers LLP Houston, Texas February 13, 2025 We have served as the Company’s auditor since 1982.

F-10 Granite Construction Incorporated GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements 1. Summary of Significant Accounting Policies Description of Business Granite Construction Incorporated is one of the largest diversified, vertically integrated civil contractors and construction materials producers in the United States, engaged in infrastructure projects including the construction of streets, roads, highways, mass transit facilities, airport infrastructure, bridges, dams, power-related facilities, utilities, tunnels, water well drilling and other infrastructure-related projects, site preparation, mining services and infrastructure services for commercial and industrial sites, railways, residential development, energy development, as well as construction management professional services. We own and lease aggregate reserves and own processing plants that are vertically integrated into our construction operations and we also produce construction materials for sale to third parties. Our operations have primary offices located in Alaska, Arizona, California, Canada, Colorado, Florida, Guam, Illinois, Mississippi, Nevada, Tennessee, Texas, Utah and Washington. Unless otherwise indicated, the terms “we,” “us,” “our,” “Company” and “Granite” refer to Granite Construction Incorporated and its wholly-owned and consolidated subsidiaries. Basis of Presentation During the first quarter of 2024, we reorganized our operational structure to more closely align with our two reportable segments, Construction and Materials. Previously, leaders within our three operating groups of California, Central and Mountain managed both Construction and Materials operations within each group. This change will allow us to better leverage our expertise within each reportable segment with leadership having direct oversight of their respective segment operations. As a result of the reorganization, we will no longer disclose financial information by operating group. There were no material impacts to our consolidated financial statements and no changes to our reportable segments. Acquisitions and Divestitures On August 9, 2024, we acquired Dickerson & Bowen, Inc. (“D&B”). D&B is an aggregates, asphalt, and highway construction company serving central and southern Mississippi. See Note 2 for more information. On November 30, 2023, we acquired Lehman-Roberts Company and Memphis Stone & Gravel Company (collectively, “LRC/MSG”). LRC/MSG operates strategically located asphalt plants and sand and gravel mines serving the greater Memphis area and northern Mississippi. See Note 2 for more information. On April 24, 2023, we acquired Coast Mountain Resources (2020) Ltd. which changed its name to Granite Infrastructure Canada, Ltd. (“Granite Canada”) on May 13, 2024. Granite Canada is a construction aggregate producer based in British Columbia, Canada operating on Malahat First Nation land. See Note 2 for more information. On March 16, 2022, we sold our trenchless and pipe rehabilitation services business, Inliner, for a purchase price of $159.7 million, subject to certain adjustments. As a result of the sale and post-closing adjustments, we received cash proceeds of $140.6 million and recognized a gain of $1.8 million. This gain is included in Other costs, net in the consolidated statements of operations for the year ended December 31, 2022. Principles of Consolidation The consolidated financial statements include the accounts of Granite Construction Incorporated and its wholly-owned and consolidated subsidiaries. All material inter-company transactions and accounts have been eliminated. Additionally, we participate in various construction joint ventures of which we are a limited member (“joint ventures”). Generally, each construction joint venture is formed to accomplish a specific project and is jointly controlled by the joint venture partners. The joint venture agreements typically provide that our interests in any profits and assets and our respective share in any losses and liabilities that may result from the performance of the contracts are limited to our stated percentage interest in the project. However, due to the joint and several nature of the performance obligations under the related owner contracts, if any of the partners fail to perform, we and the remaining partners, if any, would be responsible for performance of the outstanding work (i.e., we provide a performance guarantee). Under our joint venture contractual arrangements, we provide capital to these joint ventures in return for an ownership interest. In addition, partners dedicate resources to the joint ventures necessary to complete the contracts and are reimbursed for their cost. The operational risks of each construction joint venture are passed along to the joint venture members. As we absorb our share of these risks, our investment in each venture is exposed to potential gains and losses. We consolidate

2024 Annual Report F-11 joint ventures if we determine that through our participation we have a variable interest and are the primary beneficiary as defined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, Consolidation, and related standards. The factors we use to determine the primary beneficiary of a variable interest entity (“VIE”) may include the decision authority of each partner, which partner manages the day-to-day operations of the project and the amount of our equity investment in relation to that of our partners. Although not applicable for any of the years presented, if we determine that the power to direct the significant activities is shared equally by two or more joint venture parties, then there is no primary beneficiary and no party consolidates the VIE. If we have determined we are not the primary beneficiary of a joint venture but do exercise significant influence, we account for our share of the operations of the unconsolidated construction joint ventures on a pro rata basis in revenue and cost of revenue in the consolidated statements of operations. We record the corresponding investment balance in equity in construction joint ventures in the consolidated balance sheets except when a project is in a loss position, the investment balance is recorded as a deficit in unconsolidated construction joint ventures and is included in accrued expenses and other current liabilities in the consolidated balance sheets. Our investment in unconsolidated construction joint ventures could extend beyond one year and is within the normal operating cycle of the associated construction projects. We account for non-construction unconsolidated joint ventures under the equity method of accounting in accordance with ASC Topic 323, Investments—Equity Method and Joint Ventures, and include our share of the operations in equity in income of affiliates in the consolidated statements of operations and in investment in affiliates in the consolidated balance sheets. We also participate in “line-item” joint venture agreements under which each partner is responsible for performing certain discrete items of the total scope of contracted work. The revenue for each line-item joint venture partners’ discrete items of work is defined in the contract with the project owner and each joint venture partner bears the profitability risk associated only with its own work. There is not a single set of books and records for a line-item joint venture. Each partner accounts for its items of work individually as it would for any self-performed contract. We account for our portion of these contracts as revenue and cost of revenue in the consolidated statements of operations and in relevant balances in the consolidated balance sheets. Use of Estimates in the Preparation of Financial Statements The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of these financial statements requires management to make estimates that affect the reported amounts of assets and liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Our estimates and related judgments and assumptions are continually evaluated based on available information and experiences; however, actual amounts could differ from those estimates. Revenue Recognition Our revenue is primarily derived from construction contracts that can span several quarters or years in our Construction segment and from sales of construction related materials in our Materials segment. We recognize revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, and subsequently issued additional related Accounting Standards Updates (“ASU”s) (“Topic 606”). Topic 606 provides for a five-step model for recognizing revenue from contracts with customers as follows: 1. Identify the contract 2. Identify performance obligations 3. Determine the transaction price 4. Allocate the transaction price 5. Recognize revenue Generally, our contracts contain one performance obligation. Contracts with customers in our Materials segment are typically defined by our customary business practices and are valued at the contractual selling price per unit. Our customary business practices are for the delivery of a separately identifiable good at a point in time which is typically when delivery to the customer occurs. Contracts in our Construction segment may contain multiple distinct promises or multiple contracts within a master agreement (e.g., contracts that cross multiple locations/geographies and task orders), which we review at contract inception to determine if they represent multiple performance obligations or multiple separate contracts. This review consists of determining if promises or groups of promises are distinct within the context of the contract, including whether contracts are physically contiguous, contain task orders, purchase or sales orders, termination clauses and/or elements not related to design and/or build. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

F-12 Granite Construction Incorporated The transaction price is the amount of consideration to which we expect to be entitled in exchange for transferring goods and services to the customer. The contractual consideration from customers of our Construction segment may include both fixed amounts and variable amounts (e.g., bonuses/incentives or penalties/liquidated damages) to the extent that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved (i.e., probable and estimable). When a contract has a single performance obligation, the entire transaction price is attributed to that performance obligation. When a contract has more than one performance obligation, the transaction price is allocated to each performance obligation based on estimated relative standalone selling prices of the goods or services at the inception of the contract, which typically is determined using cost plus an appropriate margin. Subsequent to the inception of a contract in our Construction segment, the transaction price could change for various reasons, including executed or unapproved change orders, and unresolved contract modifications and/or affirmative claims. Changes that are accounted for as an adjustment to existing performance obligations are allocated on the same basis at contract inception. Otherwise, changes are accounted for as separate performance obligation(s) and the separate transaction price is allocated as discussed above. Changes are made to the transaction price from unapproved change orders to the extent the amount can be reasonably estimated and recovery is probable. On certain projects we have submitted and have pending unresolved contract modifications and/or affirmative claims (“affirmative claims”) to recover additional costs and the associated profit, if applicable, to which we believe we are entitled under the terms of contracts with customers, subcontractors, vendors or others. The owners or their authorized representatives and/or other third parties may be in partial or full agreement with the modifications or affirmative claims, or may have rejected or disagree entirely or partially as to such entitlement. Changes are made to the transaction price from affirmative claims with customers to the extent that additional revenue on a claim settlement with a customer is probable and estimable. A reduction to costs related to affirmative claims with non-customers with whom we have a contractual arrangement (“back charges”) is recognized when the estimated recovery is probable and estimable. Recognizing affirmative claims and back charge recoveries requires significant judgments of certain factors including, but not limited to, dispute resolution developments and outcomes, anticipated negotiation results, and the cost of resolving such matters. Generally, performance obligations related to contracts in our Construction segment are satisfied over time because our performance typically creates or enhances an asset that the customer controls as the asset is created or enhanced. We recognize revenue as performance obligations are satisfied and control of the promised good and/or service is transferred to the customer. Revenue in our Construction segment is ordinarily recognized over time as control is transferred to the customers by measuring the progress toward complete satisfaction of the performance obligation(s) using an input (i.e., “cost to cost”) method. Under the cost to cost method, costs incurred to-date are generally the best depiction of transfer of control. All contract costs, including those associated with affirmative claims, change orders and back charges, are recorded as incurred and revisions to estimated total costs are reflected as soon as the obligation to perform is determined. Contract costs consist of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). The accuracy of our revenue and profit recognition in a given period depends on the accuracy of our estimates of the forecasted revenue and cost to complete each project. Cost estimates for all of our significant projects use a detailed “bottom up” approach. There are a number of factors that can contribute to revisions in estimates of contract cost and profitability. The most significant of these include: • changes in costs of labor and/or materials; • subcontractor costs, availability and/or performance issues; • extended overhead and other costs due to owner, weather and other delays; • changes in productivity expectations; • changes from original design on design-build projects; • our ability to fully and promptly recover on affirmative claims and back charges for additional contract costs; • a change in the availability and proximity of equipment and materials; GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-13 • complexity in original design; • length of time to complete the project; • the availability and skill level of workers in the geographic location of the project; • site conditions that differ from those assumed in the original bid; • costs associated with scope changes; and • the customer’s ability to properly administer the contract. The foregoing factors, as well as the stage of completion of contracts in process and the mix of contracts at different margins may cause fluctuations in gross profit and gross profit margin from period to period. Significant changes in revenue and cost estimates, particularly in our larger, more complex, multi-year projects have had, and can in future periods have, a significant effect on our profitability. All state and federal government contracts and many of our other contracts provide for termination of the contract at the convenience of the party contracting with us, with provisions to pay us for work performed through the date of termination including demobilization cost. Costs to obtain our contracts (“pre-bid costs”) that are not expected to be recovered from the customer are expensed as incurred and included in selling, general and administrative expenses in our consolidated statements of operations. Although unusual, pre- bid costs that are explicitly chargeable to the customer even if the contract is not obtained are included in accounts receivable in our consolidated balance sheets when we are notified that we are not the low bidder with a corresponding reduction to selling, general and administrative expenses in our consolidated statements of operations. Unearned Revenue Unearned revenue represents the aggregate amount of the transaction price allocated to unsatisfied or partially unsatisfied performance obligations at the end of a reporting period. We generally include a project in our unearned revenue at the time a contract is awarded, the contract has been executed and to the extent we believe funding is probable. Certain contracts contain contract options that are exercisable at the option of our customers without requiring us to go through an additional competitive bidding process or contain task orders related to master contracts under which we perform work only when the customer awards specific task orders to us. Contract options and task orders are included in unearned revenue when exercised or issued, respectively. As of December 31, 2024 and 2023, unearned revenue was $3.6 billion. Approximately $2.6 billion of the December 31, 2024 unearned revenue is expected to be recognized within the next twelve months and the remaining amount will be recognized thereafter. Substantially all of the contracts in our unearned revenue may be canceled or modified at the election of the customer; however, we have not been materially adversely affected by contract cancellations or modifications in the past. Many projects are added to unearned revenue and completed within the same fiscal quarter or year and, therefore, may not be reflected in our beginning or ending unearned revenue. Balance Sheet Classifications Prepaid expenses and amounts receivable and payable under construction contracts (principally retentions) that may exist over the duration of the contract and could extend beyond one year are included in current assets and liabilities. A one-year time period is used as the basis for classifying all other current assets and liabilities. Cash and Cash Equivalents Cash equivalents are securities having maturities of three months or less from the date of purchase. Our access to joint venture cash may be limited by the provisions of the joint venture agreements. Contract Assets Our contract assets include costs and estimated earnings in excess of billings as well as amounts due under contractual retention provisions. Costs and estimated earnings in excess of billings represent amounts earned and reimbursable under contracts, including customer affirmative claim recovery estimates, and have a conditional right for billing and payment such as achievement of milestones or completion of the project. Generally, with the exception of customer affirmative claims, such unbilled amounts will become billable according to the contract terms and generally will be billed and collected over the next twelve months. Settlement with the customer of outstanding affirmative claims is dependent on the claims resolution process and could extend beyond one year. Based on our historical experience, we generally consider the collection risk related to billable amounts to be low. However, GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

F-14 Granite Construction Incorporated when events or conditions indicate that it is probable that the amounts become unbillable, the transaction price and associated contract asset is reduced. Certain contracts in our Construction segment include retention provisions to provide assurance to our customers that we will perform in accordance with the contract terms and are not considered a financing benefit under ASC Topic 606. The balances billed but not paid by customers pursuant to these provisions generally become due upon completion and acceptance of the project work or products by the customer. Marketable Securities We determine the classification of our marketable securities at the time of purchase and re-evaluate these determinations at each balance sheet date. Our marketable securities are fixed income marketable securities and are classified as held-to-maturity as we have the positive intent and ability to hold the securities to maturity. Held-to-maturity investments are stated at amortized cost and are periodically assessed for other-than-temporary impairment. Amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity and is included in interest income. The cost of securities redeemed or called is based on the specific identification method. Derivative Instruments We recognize derivative instruments as either assets or liabilities in the consolidated balance sheets at fair value using Level 2 inputs. To receive hedge accounting treatment, derivative instruments that are designated as cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions. We formally document our hedge relationships at inception, including identification of the hedging instruments and the hedged items, our risk management objectives and strategies for undertaking the hedge transaction, and the initial quantitative assessment of the hedging instrument’s effectiveness in offsetting changes in the fair value of the hedged items. The effective portion of the gain or loss on cash flow hedges is reported as a component of accumulated other comprehensive income (loss) and subsequently reclassified to the consolidated statements of operations when the periodic hedged cash flows are settled. Adjustments to fair value on derivative instruments that are not part of a designated hedging relationship are reported through the consolidated statements of operations. We do not enter into derivative instruments for speculative or trading purposes. The 2023 capped call transactions associated with the 3.75% convertible senior notes due 2028 (the “3.75% Convertible Notes”) and the 2024 capped call transactions associated with the 3.25% convertible senior notes due 2030 (the “3.25% Convertible Notes”) are indexed to our stock and meet the equity classification requirements per ASC Topic 815, Derivatives and Hedging. These capped call transactions were recorded to equity in our consolidated balance sheets and are not accounted for as a bifurcated derivative. They will not be remeasured as long as they continue to meet the conditions for equity classification. Fair Value of Financial Assets and Liabilities We measure and disclose certain financial assets and liabilities at fair value. ASC Topic 820, Fair Value Measurements and Disclosures, defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC Topic 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC Topic 820 describes three levels of inputs that may be used to measure fair value: Level 1–Quoted prices in active markets for identical assets or liabilities. Level 2–Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3–Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. We utilize the active market approach to measure fair value for our financial assets and liabilities. We report separately each class of assets and liabilities measured at fair value on a recurring basis and include assets and liabilities that are disclosed but not recorded at fair value in the fair value hierarchy. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-15 Allowance for Credit Losses Financial assets, which potentially subject us to credit losses, consist primarily of short and long-term marketable securities, receivables, contract assets and long-term notes receivables included in other noncurrent assets in our consolidated balance sheets. We measure expected credit losses of financial assets based on historical loss and other information available to management using a loss rate method applied to asset groups with categorically similar risk characteristics. These expected credit losses are recorded to an allowance for credit losses valuation account that is deducted from receivables and contract assets to present the net amount expected to be collected on the financial asset in the consolidated balance sheets. Concentrations of Credit Risk Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents, marketable securities, accounts receivable and contract assets. We maintain our cash and cash equivalents and our marketable securities with several financial institutions. We invest with high credit quality financial institutions and, by policy, limit the amount of credit exposure to any one financial institution. During the years ended December 31, 2024, 2023 and 2022, our largest volume customer, including both prime and subcontractor arrangements, was the California Department of Transportation (“Caltrans”). Revenue recognized from contracts with Caltrans during the years ended December 31, 2024, 2023 and 2022 represented $567.6 million (14.2% of total revenue), $458.2 million (13.1% of total revenue), and $348.0 million (10.5% of total revenue), respectively, which was primarily in the Construction segment. Other than Caltrans, none of our customers, including both prime and subcontractor arrangements, had revenue that individually exceeded 10% of total revenue during the year ended December 31, 2024, December 31, 2023, or December 31, 2022. The majority of our receivables are from customers concentrated in the United States. None of our customers had a receivable balance in excess of 10% of our total net receivables as of December 31, 2024 and 2023. Certain construction contracts include retention provisions that were included in contract assets as of December 31, 2024 and 2023 in our consolidated balance sheets. The balances billed but not paid by customers pursuant to these provisions generally become due upon completion and acceptance of the project work or products by the owners. The majority of the December 31, 2024 contract retention balance disclosed in Note 6 is expected to be collected within one year. We perform ongoing credit evaluations of our customers and generally do not require collateral, although the law provides us the ability to file mechanics’ liens on real property improved for private customers in the event of non-payment by such customers. Foreign Currency Transactions and Translation In the periods presented we had operations in Mexico and Canada which involved exposure to possible volatile movements in foreign currency exchange rates. We account for foreign currency exchange transactions and translation in accordance with ASC Topic 830, Foreign Currency Matters. In the third quarter of 2023, we began the wind down of our international mineral services operations which operated in Mexico and Canada. Our Materials Segment continues to have international operations in Canada. In Mexico, most of our customer contracts and a significant portion of our costs were denominated in U.S. dollars; therefore, the functional currency was U.S. dollars. In Canada, the functional currency is the local currency. Foreign currency transactions are remeasured into the functional currency with gains and losses included in other income, net in the consolidated statements of operations. The impact from foreign currency transactions was immaterial for 2024, 2023 and 2022. Assets and liabilities in functional currency are translated into U.S. dollars at exchange rates prevailing at the balance sheet date. Revenues and expenses are translated into U.S. dollars at average foreign currency exchange rates prevailing during the reporting periods. The translation adjustments from functional currency to U.S. dollars are reported in accumulated other comprehensive income on the consolidated balance sheets. Inventories Inventories relating to our operations consist primarily of quarry products, contract-specific materials and water well drilling materials, supplies, as well as mineral extraction and drilling supplies located primarily in the U.S. Cost of inventories are valued at the lower of average cost or net realizable value. We reserve quarry products based on estimated quantities of materials on hand in excess of approximately one year of demand. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

F-16 Granite Construction Incorporated Investments in Affiliates Each investment accounted for under the equity method of accounting is reviewed for impairment in accordance with ASC Topic 323, Investments—Equity Method and Joint Ventures. We account for our share of the operating results of the equity method investments in equity in income from affiliates, net in the consolidated statements of operations and as a single line item in the consolidated balance sheets as investments in affiliates. Our investments in affiliates include foreign entities, real estate ventures and an asphalt terminal entity. These investments are evaluated for impairment using the other-than-temporary impairment model, which requires an impairment charge to be recognized if our investment’s carrying amount exceeds its fair value, and the decline in fair value is deemed to be other than temporary. Recoverability is measured by comparison of carrying amounts to future undiscounted cash flows the investments are expected to generate. Events or changes in circumstances which would cause us to review undiscounted future cash flows include, but are not limited to: • significant adverse changes in legal factors or the business climate and • current period cash flow or operating losses combined with a history of losses, or a forecast of continuing losses associated with the use of the asset. In addition, events or changes in circumstances specifically related to our real estate ventures, include: • significant decreases in the market price of the asset; • accumulation of costs significantly in excess of the amount originally expected for the acquisition, development or construction of the asset; and • significant changes to the development or business plans of a project. Future undiscounted cash flows and fair value assessments for our foreign entities and for the asphalt terminal entity are estimated based on market conditions and the political climate. Future undiscounted cash flows and fair value assessments for our real estate ventures are estimated based on entitlement status, market conditions, cost of construction, debt load, development schedules, status of joint venture partners and other factors applicable to the specific project. Fair value is estimated based on the expected future cash flows attributable to the asset or group of assets and on other assumptions that market participants would use in determining fair value, such as market discount rates, transaction prices for other comparable assets, and other market data. Our estimates of cash flows may differ from actual cash flows due to, among other things, fluctuations in interest rates, decisions made by jurisdictional agencies, economic conditions, or changes to our business operations. Property and Equipment Property and equipment are stated at cost. Depreciation for construction and other equipment is calculated using accelerated methods over lives ranging from three to ten years, and the straight-line method over lives from two to twenty years for the remaining depreciable assets. We believe that accelerated methods best approximate the service provided by the construction and other equipment. Depletion of quarry property is based on the usage of depletable reserves. We frequently sell property and equipment that has reached the end of its useful life or no longer meets our needs, including depleted quarry property. At the time that an asset or an asset group meets the held for sale criteria as defined by ASC Topic 360, Property, Plant, and Equipment, depreciation is discontinued and we write it down to fair value less cost to sell, if the fair value is below the carrying value. Fair value is estimated by a variety of factors including, but not limited to, market comparative data, historical sales prices, broker quotes and third-party valuations. If material, such property is separately disclosed in the consolidated balance sheets, otherwise it is held in property and equipment until sold. The cost and accumulated depreciation or depletion of property sold or retired is removed from the consolidated balance sheets and the resulting gains or losses, if any, are reflected in operating income in the consolidated statements of operations for the period. In the case that we abandon an asset, an amount equal to the carrying amount of the asset, less salvage value, if any, will be recognized as expense in the period that the asset was abandoned. Repairs and maintenance are expensed as incurred. Costs related to the development of internal-use software during the preliminary project and post-implementation stages are expensed as incurred. Costs incurred during the application development stage are capitalized. These costs consist primarily of software, hardware and consulting fees, as well as salaries and related costs. Amounts capitalized are reported as a component of office furniture and equipment within property and equipment in the consolidated balance sheets. Capitalized software costs are depreciated using the straight-line method over the estimated useful life of the related software, which ranges from three to seven years. During the years ended December 31, 2024, 2023 and 2022, we capitalized $6.9 million, $10.1 million, $11.4 million and, respectively, of internal-use software development and related hardware costs. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-17 Long-lived Assets We review property and equipment and identifiable intangible assets for impairment at an asset group level whenever events or changes in circumstances indicate the carrying amount of an asset group may not be recoverable. Recoverability of these asset groups is measured by comparison of their carrying amounts to the future undiscounted cash flows the asset groups are expected to generate. If the asset groups are considered to be impaired, an impairment charge will be recognized equal to the amount by which the carrying amount of the asset group exceeds fair value. We group construction and plant equipment assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets. When an individual asset or group of assets is determined to no longer contribute to its vertically integrated construction and plant equipment asset group, it is assessed for impairment independently. As of December 31, 2024, identifiable intangible assets, which primarily include customer relationships, trademarks/trade names and permits, are being amortized over useful lives of one to thirty years. All identifiable intangible assets are amortized on a straight-line basis. Goodwill During the first quarter of 2024, we reorganized our operational structure to more closely align with our two reportable segments, Construction and Materials. We performed quantitative goodwill impairment tests on the affected reporting units immediately before and after the reorganization. These reporting units previously aligned with our operating group structure, but have now been combined into two legacy reporting units, Construction and Materials. For each of the affected reporting units, we calculated the estimated fair value consistent with the annual impairment assessment using the discounted cash flows and market multiple methods. These tests indicated that the estimated fair values of the affected reporting units exceeded their carrying amounts. The LRC/MSG reporting units were not impacted by the reorganization. The newly acquired D&B business has been combined with LRC/MSG to form the Granite Southeast reporting units. As of December 31, 2024, we had four reporting units in which goodwill was recorded as follows: • Legacy Construction • Legacy Materials • Granite Southeast Construction • Granite Southeast Materials We perform our goodwill impairment tests annually as of November 1 and more frequently when events and circumstances occur that indicate a possible impairment of goodwill. Examples of such events or circumstances include, but are not limited to, the following: • a significant adverse change in the business climate; • a significant adverse change in legal factors or an adverse action or assessment by a regulator; • a more likely than not expectation that a segment or a significant portion thereof will be sold; or • the testing for recoverability of a significant asset group within the segment. In accordance with ASC Topic 350, Intangibles—Goodwill and Other, we can elect to perform a qualitative assessment to test a reporting unit’s goodwill for impairment or perform a quantitative impairment test. Based on a qualitative assessment, if we determine that the fair value of a reporting unit is more likely than not to be less than its carrying amount, the quantitative impairment test will be performed. In performing the quantitative goodwill impairment tests, we calculate the estimated fair value of the reporting unit in which the goodwill is recorded using the discounted cash flows and market multiple methods. The estimated fair value is compared to the carrying amount of the reporting unit, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the fair value of the reporting unit is less than its carrying amount, goodwill is impaired and the excess of the reporting unit’s carrying amount over the fair value is recognized as a non-cash impairment charge. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

F-18 Granite Construction Incorporated Judgments inherent in these methods include the determination of appropriate discount rates, the amount and timing of expected future cash flows, revenue and margin growth rates, and appropriate benchmark companies. The cash flows used in our discounted cash flow model are based on five-year financial forecasts developed internally by management adjusted for market participant-based assumptions. Our discount rate assumptions are based on an assessment of the equity cost of capital and appropriate capital structure for our reporting units. To assess for reasonableness, we compare the estimated fair values of the reporting units to our current market capitalization. For our 2024 annual goodwill impairment test, we elected to perform a qualitative assessment on our Legacy Construction and Legacy Materials reporting units and it was determined that no impairment indicators existed and it was more likely than not that the fair values were greater than the carrying amounts; therefore, no quantitative goodwill impairment test was performed for these reporting units. Factors we considered in our qualitative assessment were macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, changes in management or key personnel, changes in strategy, changes in customers and changes in the composition or carrying amount of the reporting unit’s net assets. We performed quantitative goodwill impairment tests on both of our Granite Southeast reporting units. We calculated the estimated fair value using the discounted cash flows and market multiple methods. These tests indicated that the estimated fair values of these reporting units exceeded their carrying amounts and we concluded that goodwill was not impaired. For our 2023 annual goodwill impairment test, we elected to perform a qualitative assessment on each of our reporting units and we determined that it was more likely than not that the fair values were greater than the carrying amounts; therefore, no quantitative goodwill impairment test was performed for these reporting units. Factors we considered in our qualitative assessment were macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, changes in management or key personnel, changes in strategy, changes in customers and changes in the composition or carrying amount of the reporting unit’s net assets. In the third quarter of 2023, in connection with our decision to wind down our international mineral services operations, we performed an interim goodwill impairment test on the former Mountain Group Construction reporting unit, which resulted in a $4.5 million non-cash impairment charge. This charge is included in Other costs, net in the consolidated statements of operations. Right of use Assets and Lease Liabilities A lease contract conveys the right to use an underlying asset for a period of time in exchange for consideration. At inception, we determine whether a contract contains a lease by determining if there is an identified asset and if the contract conveys the right to control the use of the identified asset in exchange for consideration over a period of time. At lease commencement, we measure and record a lease liability equal to the present value of the remaining lease payments, generally discounted using the borrowing rate on our secured debt as the implicit rate is not readily determinable on many of our leases. We use a quarterly maturity discount rate if it is not materially different than the discount rates applied to each of the leases in the portfolio. On the lease commencement date, the amount of the right of use assets consists of the following: • the amount of the initial measurement of the lease liability; • any lease payments made at or before the commencement date, minus any lease incentives received; and • any initial direct costs incurred. On a quarterly basis, we determine if subcontractor, vendor or service provider agreements contain embedded leases by assessing if an asset is explicitly or implicitly specified in the agreement and the counterparty has the right to substitute the asset. Most of our lease contracts do not have the option to extend or renew. We assess the option for individual leases, and we generally consider the base term to be the term of lease contracts. Lease contracts may contain non-lease components for which we elected to include both the lease and non-lease components as a single component and account for it as a lease. Contract Liabilities Our contract liabilities consist of billings in excess of costs and estimated earnings, net of the related contract retention and provisions for losses. Billings in excess of costs and estimated earnings are billings to customers on contracts in advance of work performed, including advance payments negotiated as a contract condition. Generally, unearned project-related costs will be GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-19 earned over the next twelve months. Provisions for losses are recognized in the consolidated statements of operations at the uncompleted performance obligation level for the amount of total estimated losses in the period that evidence indicates that the estimated total cost of a performance obligation exceeds its estimated total revenue. Asset Retirement Obligations We account for the costs related to legal obligations to reclaim aggregate mining sites and other facilities by recording our estimated asset retirement obligation at fair value using Level 3 inputs, capitalizing the estimated liability as part of the related asset’s carrying amount and allocating it to expense over the asset’s useful life. Warranties Many of our construction contracts contain warranty provisions covering defects in equipment, materials, design or workmanship that generally run for less than two years after our customer accepts the contract. Because of the nature of our projects, including contract owner inspections of the work both during construction and prior to acceptance, we have not experienced material warranty costs for these short-term warranties and, therefore, do not believe an accrual for these costs is necessary. Certain construction contracts carry longer warranty periods, ranging from two to ten years, for which we have accrued an estimate of warranty cost. Our warranty liability is estimated based on our experience with the type of work and any known risks relative to the project. Total warranty liability was not material as of December 31, 2024 and 2023. Accrued Insurance Costs We carry insurance policies to cover various risks, including general liability, automobile liability, workers compensation and employee medical expenses under which we are liable to reimburse the insurance company for certain losses. The amounts for which we are liable range from the first $0.5 million to $1.5 million per occurrence. We accrue for probable losses, both reported and unreported, that are reasonably estimable using actuarial methods based on historic trends, modified, if necessary, by recent events. The establishment of accruals for estimated losses associated with our insurance policies are based on actuarial studies that include known facts and interpretations of circumstances, including our experience with similar cases and historical trends involving claim payment patterns, pending levels of unpaid claims, claim severity, frequency patterns and changing regulatory and legal environments. Changes in our loss assumptions caused by changes in actual experience would affect our assessment of the ultimate liability and could have an effect on our operating results and financial position. Surety Bonds We generally are required to provide various types of surety bonds that provide an additional measure of security for our performance under certain public and private sector contracts. Performance bonds do not have stated expiration dates; rather, we are generally released from the bonds after the owner accepts the work performed under contract. The ability to maintain bonding capacity to support our current and future level of contracting requires that we maintain cash and working capital balances satisfactory to our sureties. Performance Guarantees The agreements with our joint venture partners (“partner(s)”) for both construction joint ventures and line item joint ventures define each partner’s management role and financial responsibility in the project. The amount of operational exposure is generally limited to our stated ownership interest. However, due to the joint and several nature of the performance obligations under the related owner contracts, if any of the partners fail to perform, we and the remaining partners, if any, would be responsible for performance of the outstanding work (i.e., we provide a performance guarantee). We estimate our liability for performance guarantees for our unconsolidated and line item joint ventures using estimated partner bond rates, which are Level 2 inputs, and include them in accrued expenses and other current liabilities with a corresponding increase in equity in construction joint ventures in the consolidated balance sheets. We reassess our liability when and if changes in circumstances occur. The liability and corresponding asset are removed from the consolidated balance sheets upon completion and customer acceptance of the project. Circumstances that could lead to a loss under these agreements beyond our stated ownership interest include the failure of a partner to contribute additional funds to the venture in the event the project incurs a loss or additional costs that we could incur should a partner fail to provide the services and resources that it had committed to provide in the agreement. We are not able to estimate amounts that may be required beyond the remaining cost of the work to be performed. These costs could be offset by billings to the customer or by proceeds from our partners’ corporate and/or other guarantees. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

F-20 Granite Construction Incorporated Contingencies We are currently involved in various claims and legal proceedings. Loss contingency provisions are recorded if the potential loss from any asserted or un-asserted claim or legal proceeding is considered probable and the amount can be reasonably estimated. If a potential loss is considered probable but only a range of loss can be determined, the low-end of the range is recorded. These accruals represent management’s best estimate of probable loss. Disclosure is also provided when it is reasonably possible and estimable that a loss will be incurred or when it is reasonably possible that the amount of a loss will exceed the amount recorded. Significant judgment is required in both the determination of probability of loss and the determination as to whether an exposure is reasonably estimable. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to claims and litigation and may revise our estimates. We expense associated legal costs as they are incurred. See Note 20 for additional information. Stock-Based Compensation We measure and recognize compensation expense, net of forfeitures, over the requisite vesting periods for all stock-based payment awards made and we recognize forfeitures as they occur. Stock-based compensation is included in selling, general and administrative expenses and cost of revenue on our consolidated statements of operations. Other Costs Other costs, net in the consolidated statements of operations are expensed as they are incurred and include legal fees for the defense of a former Company officer in his ongoing civil litigation with the Securities and Exchange Commission, reorganization costs, strategic acquisition and divestiture expenses and non-cash impairment charges. In addition to the aforementioned costs, 2023 also included a litigation charge and 2022 included a gain on sale of a business. Income Taxes Deferred taxes are provided on a liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss carry-forwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities in the consolidated financial statements and their respective tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Disproportionate income tax effects which are stranded in accumulated other comprehensive income will be released using the item-by-item approach. We report a liability in accrued expenses and other current liabilities and in other long-term liabilities in the consolidated balance sheets for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. We recognize interest and penalties, if any, related to unrecognized tax benefits in interest expense and other income, net in the consolidated statements of operations. Computation of Earnings per Share Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares include common share equivalents under the equity incentive plans and common share equivalents issuable under our 3.25% Convertible Notes, 3.75% Convertible Notes and 2.75% Convertible Notes using the if-converted method. See Note 14 for further discussion of the convertible notes. Convertible Notes ASU 2020-06 simplified the accounting for convertible instruments resulting in accounting for convertible debt instruments as a single liability measured at its amortized cost. We adopted ASU 2020-06 effective January 1, 2022, using the modified retrospective transition approach under which financial results reported in prior periods were not adjusted. Upon adoption of this new accounting guidance, the 2.75% Convertible Notes were accounted for entirely as a liability, and the issuance costs were accounted for wholly as debt issuance costs. Recently Issued Accounting Pronouncements We closely monitor all ASUs issued by the FASB and other authoritative guidance. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-21 In August 2023, the FASB issued ASU 2023-05, Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement, which requires that a joint venture apply a new basis of accounting upon formation. As a result, a newly formed joint venture, upon formation, would initially measure its assets and liabilities at fair value. This ASU is effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. We do not expect this ASU to have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments intended to improve the effectiveness of income tax disclosures. These new disclosure requirements are effective prospectively commencing with our annual report for the year ending December 31, 2025. We do not expect the adoption of this ASU to have a material impact on our consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires public companies to disclose additional information about certain expenses in the notes to financial statements, enhancing transparency and providing more detailed insights for investors and other stakeholders. This ASU is effective commencing with our annual report for the year ending December 31, 2027, and quarterly periods thereafter. We are currently evaluating the impact of this standard on our consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-04, Induced Conversions of Convertible Debt Instruments. The new guidance clarifies the assessment of whether a transaction should be accounted for as an induced conversion or extinguishment of convertible debt when changes are made to conversion features as part of an offer to settle the instrument. The guidance is effective for fiscal years beginning after December 15, 2025, with early adoption permitted, and it can be adopted either on a prospective or retrospective basis. We are currently evaluating the impact of this standard on our consolidated financial statements and related disclosures. Recently Adopted Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting—Improvements to Reportable Segment Disclosures, which enhances the disclosures regarding an entity’s reportable segments and addresses requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. We adopted this ASU retrospectively for the year ended December 31, 2024. See Note 21 for more information. 2. Acquisitions Dickerson & Bowen, Inc. On August 9, 2024, we completed the acquisition of Dickerson & Bowen, Inc. (“D&B”) for $125.5 million in cash, subject to customary closing adjustments. D&B is an aggregates, asphalt and highway construction company serving central and southern Mississippi which expands our footprint in that region. D&B’s customers are in both the public and private sectors. We have accounted for this transaction in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations (“ASC 805”). D&B’s results have been included in the Construction and Materials segments since the acquisition date. Revenue and gross profit attributable to D&B for the year ended December 31, 2024 were $37.8 million and $9.5 million, respectively. Pro Forma Financial Information (Unaudited) The unaudited pro forma financial information in the table below summarizes the combined results of operations of Granite and D&B as though the companies had been combined as of January 1, 2023. The pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place on January 1, 2023, nor does it intend to be a projection of future results. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

F-22 Granite Construction Incorporated Years Ended December 31, 2024 2023 (unaudited, in thousands, except per share amounts) Revenue $ 4,062,791 $ 3,614,443 Net income attributable to Granite Construction Incorporated $ 134,470 $ 41,119 Basic net income per share attributable to common shareholders $ 3.07 $ 0.94 Diluted net income per share attributable to common shareholders $ 2.56 $ 0.78 These amounts have been calculated after applying Granite’s accounting policies and adjusting the results of D&B to reflect the additional depreciation and amortization that would have been recorded assuming the fair value adjustments to property and equipment and intangible assets had been applied starting on January 1, 2023. Acquisition and integration expenses related to D&B that were incurred during the year ended December 31, 2024 are reflected in the year ended December 31, 2023 due to the assumed timing of the transaction. The statutory tax rate of 26% was used for both 2024 and 2023 for the pro forma adjustments. During the year ended December 31, 2024, we incurred $2.5 million of acquisition and integration expenses included in Other costs, net associated with the D&B acquisition which were primarily related to professional services. Preliminary Purchase Price Allocation In accordance with ASC 805, the preliminary purchase price was allocated to assets acquired and liabilities assumed based on their estimated fair values as of August 9, 2024. These estimates are subject to revision, which may result in adjustments to the values disclosed below. There are certain provisional estimates that are subject to finalization. As we continue to integrate the acquired business, we may obtain additional information which may result in revisions to preliminary valuation assumptions, estimates and the resulting fair values presented herein. We expect to finalize these amounts within 12 months from the acquisition date. For the purpose of this allocation, the contractual purchase price has been adjusted to exclude cash acquired and include closing adjustments, resulting in a preliminary purchase price of $121.2 million. The tangible and identifiable intangible assets acquired, net of liabilities assumed, were $25.4 million and $27.9 million, respectively. This generated acquired goodwill of $67.9 million, none of which is tax deductible. The most significant assets acquired were $38.1 million of property and equipment and a $18.2 million customer relationship intangible asset. Goodwill Goodwill represents the excess of the purchase price over the fair value of the underlying net tangible and identifiable intangible assets. Of the acquired goodwill, $47.2 million is in the Materials segment and $20.7 million is in the Construction segment. The factors that contributed to the recognition of goodwill from this acquisition include strengthening and expanding our vertically integrated southeast home market as well as expected synergies. Identifiable Intangible Assets The following table lists identifiable intangible assets from the D&B acquisition that are included in intangible assets in the consolidated balance sheets as of December 31, 2024 (in thousands): Useful Lives (Years) Gross Value Accumulated Amortization Net Value Customer relationships 20 $ 18,200 $ (379) $ 17,821 Backlog 1 600 (231) 369 Trademarks/trade name 10 7,500 (312) 7,188 Permits 10 1,600 (58) 1,542 Total intangible assets $ 27,900 $ (980) $ 26,920 The fair value of customer relationships was estimated as of the acquisition date utilizing the multi-period excess earnings method. This method discounts to present value the projected cash flows attributable to the customer relationships. The significant estimates and assumptions used in determining the fair value included discount rates, revenue growth rates, projected earnings before interest, taxes, depreciation and amortization (“EBITDA”) margins and customer revenue attrition rates. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-23 The amortization expense related to the acquired identifiable intangible assets for the year ended December 31, 2024 was included in cost of revenue and selling, general and administrative expenses in the consolidated statements of operations. All of the acquired identifiable intangible assets will be amortized on a straight-line basis. Amortization expense related to the acquired identifiable intangible asset balances at December 31, 2024 is expected to be recorded in the future as follows: $2.2 million in 2025; $1.8 million in each year from 2026 to 2029; and $17.5 million thereafter. LRC/MSG On November 30, 2023, we completed the acquisition of LRC/MSG for $278.0 million, subject to customary closing adjustments, plus an estimated amount related to tax make-whole agreements with the seller. We purchased all of the outstanding equity interests in LRC/MSG and the purchase price was funded by a new $150.0 million senior secured term loan, a draw of $100 million under our existing revolver and the remainder from cash on hand. Both the senior secured term loan and the draw under the revolver were fully repaid during the first half of 2024. The acquired businesses are longstanding asphalt paving and asphalt and aggregates producers and suppliers. LRC/MSG operates strategically located asphalt plants and sand and gravel mines serving the greater Memphis area and northern Mississippi. LRC/MSG’s results have been included in the Construction and Materials segments since the acquisition date. LRC/MSG’s customers are in both the public and private sectors. Revenue attributable to LRC/MSG for the years ended December 31, 2024 and 2023 was $147.3 million and $7.7 million, respectively. Gross profit (loss) attributable to LRC/MSG for the years ended December 31, 2024 and 2023 was a profit of $8.7 million and loss of $1.5 million, respectively. Pro Forma Financial Information (Unaudited) The unaudited pro forma financial information in the table below summarizes the combined results of operations of Granite and LRC/MSG as though the companies had been combined as of January 1, 2022. The Granite Canada acquisition discussed below is not included in the pro forma financial information as the effects of the business would not have a material impact. The pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place on January 1, 2022, nor does it intend to be a projection of future results. Years Ended December 31, 2023 2022 (unaudited, in thousands, except per share amounts) Revenue $ 3,720,449 $ 3,485,186 Net income $ 55,025 $ 72,219 Basic net income per share attributable to common shareholders $ 1.25 $ 1.62 Diluted net income per share attributable to common shareholders $ 1.19 $ 1.49 These amounts have been calculated after applying Granite’s accounting policies and adjusting the results of LRC/MSG to reflect the additional depreciation and amortization that would have been recorded assuming the fair value adjustments to property and equipment and intangible assets had been applied starting on January 1, 2022. Additionally, these amounts reflect adjustment for additional interest that would have been incurred as a result of incurring debt for the acquisition over the periods in the pro forma financial information. Acquisition and integration expenses related to LRC/MSG that were incurred during the year ended December 31, 2023 are reflected in the year ended December 31, 2022 due to the assumed timing of the transaction. The statutory tax rate of 26% was used for both 2023 and 2022 for the pro forma adjustments. During the year ended December 31, 2023, we incurred $5.0 million of acquisition and integration expenses included in Other costs, net associated with the LRC/MSG and Granite Canada acquisitions which were primarily related to professional services. Purchase Price Allocation In accordance with ASC 805, the total purchase price and assumed liabilities were allocated to the net tangible and identifiable intangible assets based on their estimated fair values as of the acquisition date, as presented in the table below. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

F-24 Granite Construction Incorporated We recorded a $22.0 million provisional estimate related to tax make-whole agreements with the seller at the time of the acquisition. In the second quarter of 2024, the former owners of LRC/MSG determined their personal tax burden related to the sale of the businesses which allowed us to finalize our tax make-whole obligation. Our obligation was $7.1 million, which was paid in June 2024. During 2024, we made measurement period adjustments to reflect facts and circumstances in existence as of the acquisition date. These adjustments included a $4.6 million net increase from net working capital adjustments and a $2.2 million net decrease in the value of the net tangible and identifiable intangible assets acquired, offset by a $14.9 million decrease in the estimated obligation associated with the tax make-whole agreements noted above. The impact of these adjustments was a decrease in goodwill of $8.1 million. We paid $13.2 million during the 2024 associated with the acquisition of LRC/MSG, which includes $6.1 million for working capital adjustments and $7.1 million for the tax make-whole obligation. We finalized the purchase price allocation during the third quarter of 2024. The following table presents the final purchase price allocation: (in thousands) Assets Cash and cash equivalents $ 12,798 Receivables 18,373 Contract assets 3,388 Inventories 13,738 Other current assets 1,032 Property and equipment 86,329 Right of use assets 15,539 Other noncurrent assets 3,718 Total tangible assets $ 154,915 Identifiable intangible assets $ 107,460 Liabilities Accounts payable $ 6,806 Contract liabilities 3,213 Accrued expenses and other current liabilities 10,166 Long-term lease liabilities 15,558 Other long-term liabilities 5,960 Total liabilities assumed $ 41,703 Total tangible and identifiable net assets acquired $ 220,672 Goodwill 72,744 Purchase price $ 293,416 Goodwill The primary factor that contributed to the recognition of goodwill from the acquisition of LRC/MSG was expansion of our vertically integrated home market strategy into the southeastern United States. For the LRC/MSG acquisition, we recorded $72.7 million of goodwill which will be deductible for tax purposes. $46.7 million and $26.0 million were allocated to our Construction and Materials segments, respectively. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-25 Identifiable Intangible assets The following table lists identifiable intangible assets from the LRC/MSG acquisition that are included in intangible assets in the consolidated balance sheets as of December 31, 2024 (in thousands): Useful Lives (Years) Gross Value Accumulated Amortization Net Value Customer relationships 20 $ 78,860 $ (4,272) $ 74,588 Backlog 1 6,500 (6,500) — Trademarks/trade name 10 15,100 (1,636) 13,464 Permits 10 7,000 (758) 6,242 Total intangible assets $ 107,460 $ (13,166) $ 94,294 The fair value of customer relationships was estimated as of the acquisition date utilizing the multi-period excess earnings method. This method discounts to present value the projected cash flows attributable to the customer relationships. The significant estimates and assumptions used in determining the fair value included discount rates, revenue growth rates, projected EBITDA margins and customer revenue attrition rates. The amortization expense related to the acquired identifiable intangible assets for the year ended December 31, 2024 was included in cost of revenue and selling, general and administrative expenses in the consolidated statements of operations. All of the acquired identifiable intangible assets will be amortized on a straight-line basis. Amortization expense related to the acquired identifiable intangible asset balances is expected to be recorded in the future as follows: $6.2 million in each year from 2025 to 2029; and $63.5 million thereafter. Coast Mountain Resources On April 24, 2023, we acquired Coast Mountain Resources (2020) Ltd. which changed its name to Granite Infrastructure Canada, Ltd. (“Granite Canada”) on May 13, 2024. Granite Canada is a construction aggregate producer based in British Columbia, Canada operating on Malahat First Nation land. Granite Canada results are reported in the Materials segment. This acquisition did not have a material impact on our financial statements. The primary factor that contributed to the recognition of goodwill from the acquisition of Granite Canada was strengthening our existing vertically integrated home markets in the western United States. For the Granite Canada acquisition, we recorded $5.1 million in goodwill that was allocated to our Materials segment and will not be tax deductible for income tax purposes. 3. Revisions in Estimates Our profit recognition related to construction contracts is based on estimates of transaction price and costs to complete each project. These estimates can vary significantly in the normal course of business as projects progress, circumstances develop and evolve, and uncertainties are resolved. Changes in estimates of transaction price and costs to complete may result in the reversal of previously recognized revenue if the current estimate adversely differs from the previous estimate. In addition, the estimated or actual recovery related to estimated costs associated with unresolved affirmative claims and back charges may be recorded in future periods or may be at values below the associated cost, which can cause fluctuations in the gross profit impact from revisions in estimates. When we experience significant revisions in our estimates, we undergo a process that includes reviewing the nature of the changes to ensure that there are no material amounts that should have been recorded in a prior period rather than as revisions in estimates for the current period. For revisions in estimates, generally we use the cumulative catch-up method for changes to the transaction price that are part of a single performance obligation. Under this method, revisions in estimates are accounted for in their entirety in the period of change. There can be no assurance that we will not experience further changes in circumstances or otherwise be required to revise our estimates in the future. In our review of these changes for the years ended December 31, 2024, 2023 and 2022, we did not identify any material amounts that should have been recorded in a prior period. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

F-26 Granite Construction Incorporated The projects with increases and decreases from revisions in estimates, which individually had an impact of $5.0 million or more on gross profit, are summarized as follows (dollars in millions, except per share data): Increases Years Ended December 31, 2024 2023 2022 Number of projects with upward estimate changes 3 1 2 Range of increase in gross profit from each project, net $ 6.1 – 10.3 $ 8.1 $ 5.4 – 6.8 Increase to project profitability, net $ 25.6 $ 8.1 $ 12.1 Increase to net income $ 18.3 $ 6.9 $ 9.7 Amounts attributable to non-controlling interests $ — $ 3.2 $ 2.7 Increase to net income attributable to Granite Construction Incorporated $ 18.3 $ 3.6 $ 7.0 Increase to net income per diluted share attributable to common shareholders $ 0.35 $ 0.07 $ 0.13 The increases during the year ended December 31, 2024 were due to changes in the estimated amount of probable recovery on outstanding claims, production at a higher rate than anticipated and changes in the estimated transaction price related to contract modifications resulting from revisions to project work plans, permitting and scheduling. The increase during the year ended December 31, 2023 was due to decreases in estimated costs from mitigated risks. The increases during the year ended December 31, 2022 were due to production at a higher rate than anticipated and a decrease in estimated cost from mitigated risks. Decreases Years Ended December 31, 2024 2023 2022 Number of projects with downward estimate changes 4 6 8 Range of reduction in gross profit from each project, net $5.6 – 24.2 $5.1 – 54.9 $5.6 – 32.2 Decrease to project profitability, net $ 50.2 $ 96.9 $ 92.2 Decrease to net income $ 37.0 $ 79.6 $ 74.1 Amounts attributable to non-controlling interests $ 3.9 $ 29.8 $ 21.7 Decrease to net income attributable to Granite Construction Incorporated $ 33.1 $ 49.8 $ 52.4 Decrease to net income per diluted share attributable to common shareholders $ 0.63 $ 0.95 $ 1.00 The decreases during the year ended December 31, 2024 were due to additional costs related to changes in project duration, lower productivity than originally anticipated and increased labor and materials costs. The decreases during the year ended December 31, 2023 were due to a change in the estimated amount of probable recovery on an outstanding claim, additional costs related to changes in project durations, lower productivity than originally anticipated, increased labor and materials costs and disputed work being performed where there are ongoing legal claims. The decreases during the year ended December 31, 2022 were due to additional costs related to extended project duration, increased labor and materials costs, and disputed work being performed where there are ongoing legal claims. 4. Disaggregation of Revenue As discussed in Note 1, during the first quarter of 2024, we reorganized our operational structure to more closely align with our two reportable segments, Construction and Materials. Previously, leaders within our three former operating groups of California, Central and Mountain managed both Construction and Materials operations within each group. As a result of the reorganization, we will no longer disclose financial information by operating group and we have updated our presentation of disaggregated revenue. The prior years’ disaggregation of revenue amounts have been recast to conform with the current period presentation. Revenue is disaggregated by reportable segment (see Note 21) and customer type, which we believe best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-27 Customer Type Customers in our Construction segment are predominantly in the public sector which includes certain federal agencies, state departments of transportation, local transit authorities, county and city public works departments and school districts. Our private sector customers include, but are not limited to, developers, utilities and private owners of industrial, commercial and residential sites. Customers of our Materials segment include internal usage by our own construction projects, as well as third-party customers. Based on the nature of the Materials business, it is not meaningful to disaggregate revenue by customer type. The following table presents our revenue disaggregated by reportable segment and by customer type for the Construction segment: Years ended December 31, (in thousands) 2024 2023 2022 Construction segment revenue: Public $ 2,531,379 $ 2,064,078 $ 1,891,338 Private 883,846 928,176 912,597 Total Construction segment revenue 3,415,225 2,992,254 2,803,935 Materials segment revenue 592,349 516,884 497,321 Total revenue $ 4,007,574 $ 3,509,138 $ 3,301,256 5. Unearned Revenue The following table presents our unearned revenue as of the respective periods: (in thousands) December 31, 2024 December 31, 2023 Public $ 2,801,273 $ 2,892,255 Private 783,105 704,421 Total $ 3,584,378 $ 3,596,676 All unearned revenue is in the Construction segment. Approximately $2.6 billion of the December 31, 2024 unearned revenue is expected to be recognized within the next twelve months and the remaining amount will be recognized thereafter. 6. Contract Assets and Liabilities As a result of changes in contract transaction price related to performance obligations that were satisfied or partially satisfied prior to the end of the periods we recognized revenue of $220.7 million, $147.4 million and $182.8 million during the years ended December 31, 2024, 2023 and 2022, respectively. The changes in contract transaction price were from items such as executed or estimated change orders and unresolved contract modifications and claims. As of December 31, 2024 and 2023, the aggregate claim recovery estimates included in contract asset and liability balances were approximately $46.6 million and $77.9 million, respectively. The components of the contract asset balances as of the respective dates were as follows: (in thousands) December 31, 2024 December 31, 2023 Costs in excess of billings and estimated earnings $ 139,436 $ 100,106 Contract retention 188,917 162,881 Total contract assets $ 328,353 $ 262,987 GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

F-28 Granite Construction Incorporated The increase in contract assets is primarily due to increasing costs in excess of billings and estimated earnings balances from unresolved disputed work related to certain ongoing projects and increased retention balances from ongoing projects. As of December 31, 2024, no contract retention receivable individually exceeded 10% of total contract assets. As of December 31, 2023, contract retention receivable from Brightline Trains Florida LLC represented 11.1% of total contract assets and no other contract retention receivable individually exceeded 10% of total contract assets. The majority of the contract retention balance is expected to be collected within one year. As work is performed, revenue is recognized and the corresponding contract liabilities are reduced. During the years ended December 31, 2024 and 2023 and 2022, we recognized revenue of $276.6 million, $191.8 million and $223.7 million, respectively, that was included in the contract liability balances at December 31, 2023, 2022 and 2021, respectively. The components of the contract liability balances as of the respective dates were as follows: (in thousands) December 31, 2024 December 31, 2023 Billings in excess of costs and estimated earnings $ 288,495 $ 227,913 Provisions for losses 11,176 15,935 Total contract liabilities $ 299,671 $ 243,848 The increase in contract liabilities is primarily due to increases in billings in excess of costs on new projects partially offset by reductions in provisions for losses as certain loss projects progress towards completion. 7. Receivables, net Receivables include billed and unbilled amounts for services provided to clients for which we have an unconditional right to payment as of the end of the applicable period and generally do not bear interest. The following table presents major categories of receivables: (in thousands) December 31, 2024 December 31, 2023 Contracts completed and in progress: Billed $ 250,656 $ 343,190 Unbilled 127,776 119,170 Total contracts completed and in progress 378,432 462,360 Materials sales 55,770 61,808 Other 78,309 76,084 Total gross receivables 512,511 600,252 Less: allowance for credit losses 769 1,547 Total net receivables $ 511,742 $ 598,705 Included in other receivables at December 31, 2024 and 2023 were items such as estimated recovery from back charge claims, notes receivable, fuel tax refunds and income tax refunds. Other receivables at both December 31, 2024 and 2023 also included $25.0 million of working capital contributions in the form of a loan to a partner in one of our unconsolidated joint ventures, plus accrued interest. No receivable individually exceeded 10% of total net receivables at any of these dates. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-29 8. Fair Value Measurement The following tables summarize significant assets and liabilities measured at fair value in the consolidated balance sheets on a recurring basis for each of the fair value levels (in thousands): Fair Value Measurement at Reporting Date Using December 31, 2024 Level 1 Level 2 Level 3 Total Cash equivalents: Money market funds $ 73,031 $ — $ — $ 73,031 Total assets $ 73,031 $ — $ — $ 73,031 Accrued and other current liabilities: Heating oil swaps $ — $ 531 $ — $ 531 Diesel collars — 177 — 177 Total liabilities $ — $ 708 $ — $ 708 December 31, 2023 Cash equivalents: Money market funds $ 101,275 $ — $ — $ 101,275 Total assets $ 101,275 $ — $ — $ 101,275 Accrued and other current liabilities: Interest rate swap $ — $ 126 $ — $ 126 Heating oil swaps — 153 — 153 Diesel collars — 802 — 802 Total liabilities $ — $ 1,081 $ — $ 1,081 Interest Rate Swap In connection with entering into Amendment No. 2 of the Fourth Amended and Restated Credit Agreement in November 2023, we entered into an interest rate swap designated as a cash flow hedge with an initial notional amount of $75.0 million and an effective date of December 2023 and a maturity date of June 2027. In conjunction with the payoff of our term loan in June 2024, the interest rate swap was terminated resulting in an immaterial gain. Commodity Derivatives In 2023 and 2024, we entered into collar contracts and commodity swaps to reduce our price exposure on diesel consumption and heating oil consumption, respectively. The collars and swaps were not designated as hedges and will be treated as a mark-to- market derivative instruments through their maturity dates. The financial statement impact of the collar contracts and commodity swaps was immaterial for the years ended December 31, 2024 and 2023. In April 2024 and December 2022, we entered into commodity swaps designated as cash flow hedges to reduce our price exposure on crude oil with maturity dates of October 31, 2024 and October 31, 2023, respectively. The financial statement impact of these swaps was immaterial during the years ended December 31, 2024, 2023 and 2022.

F-30 Granite Construction Incorporated Other Assets and Liabilities The carrying values and estimated fair values of our financial instruments that are not required to be recorded at fair value in the consolidated balance sheets were as follows (in thousands): December 31, 2024 December 31, 2023 (in thousands) Fair Value Hierarchy Carrying Value Fair Value Carrying Value Fair Value Assets: Held-to-maturity marketable securities(1) Level 1 $ 7,311 $ 7,312 $ 35,863 $ 35,357 Liabilities (including current maturities): 3.75% Convertible Notes(2) Level 2 $373,750 $738,724 $373,750 $475,601 3.25% Convertible Notes(2) Level 2 $373,750 $491,582 $ — $ — 2.75% Convertible Notes(2) Level 2 $ — $ — $ 31,338 $ 51,045 Credit Agreement—Term Loan(2) Level 3 $ — $ — $150,000 $153,585 Credit Agreement—Revolver(2) Level 3 $ — $ — $100,000 $102,317 (1) All marketable securities were classified as held-to-maturity and consisted of U.S. Government and agency obligations as of December 31, 2024 and 2023. (2) The fair values of our 3.25% convertible senior notes due 2030 (the "3.25% Convertible Notes"), our 3.75% convertible senior notes due 2028 (the "3.75% Convertible Notes") and our 2.75% convertible senior notes due 2024 (the "2.75% Convertible Notes") are based on the median price of the notes in an active market. The fair value of the Credit Agreement is based on borrowing rates available to us for long-term loans with similar terms, average maturities, and credit risk. See Note 14 for more information about our convertible notes and the Credit Agreement. The carrying value of marketable securities approximates their fair value as determined by market quotes. Rates currently available to us for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt. The carrying value of receivables and other amounts arising out of normal contract activities, including retentions, which may be settled beyond one year, is estimated to approximate fair value. At least annually, we measure certain nonfinancial assets and liabilities at fair value on a nonrecurring basis. As of December 31, 2024 and 2023, the nonfinancial assets and liabilities included our asset retirement and reclamation obligations, as well as assets and corresponding liabilities associated with performance guarantees. Asset retirement and reclamation obligations were measured using Level 3 inputs and performance guarantees were measured using Level 2 inputs. Asset retirement and reclamation obligations were initially measured using internal discounted cash flow calculations based upon our estimates of future retirement costs. To determine the fair value of the obligation, we estimate the cost for a third-party to perform the legally required reclamation including a reasonable profit margin. This cost is then increased for future estimated inflation based on the estimated years to complete and discounted to fair value using present value techniques with a credit-adjusted, risk-free rate. In estimating the settlement date, we evaluate the current facts and conditions to determine the most likely settlement date. We review reclamation obligations at least annually for a revision to the cost or a change in the estimated settlement date. Additionally, reclamation obligations are reviewed in the period that a triggering event occurs that would result in either a revision to the cost or a change in the estimated settlement date. See Note 11 for details of the asset retirement obligation balances. We estimate our liability for performance guarantees for our unconsolidated construction joint ventures and line item joint ventures using estimated partner bond rates, which are Level 2 inputs, and include them in accrued expenses and other current liabilities (see Note 13) with a corresponding increase in equity in construction joint ventures in the consolidated balance sheets. See Note 1 for further discussion of performance guarantees. During the years ended December 31, 2024 and 2023, we had no material nonfinancial asset and liability fair value adjustments.

2024 Annual Report F-31 9. Construction Joint Ventures We participate in various construction joint ventures. As discussed in Note 1, we have determined that certain of these joint ventures are consolidated because they are VIEs and we are the primary beneficiary. We continually evaluate whether there are changes in the status of the VIEs or changes to the primary beneficiary designation of the VIE. Based on our assessments during the years ended December 31, 2024, 2023 and 2022, we determined no change was required for existing joint ventures. Due to the joint and several nature of the performance obligations under the related owner contracts, if any of our partners fail to perform, we and the remaining partners, if any, would be responsible for performance of the outstanding work (i.e., we provide a performance guarantee). At December 31, 2024, there was $100.6 million of remaining contract value on unconsolidated and line item construction joint venture contracts of which $35.6 million represented our share and the remaining $65.0 million represented our partners’ share. We are not able to estimate amounts that may be required beyond the current remaining forecasted cost of the work to be performed. These forecasted costs could be offset by billings to the customer or by proceeds from our partners’ corporate and/or other guarantees. See Note 13 for disclosure of the performance guarantee amounts recorded in the consolidated balance sheets and Note 1 for additional discussion regarding performance guarantees. Consolidated Construction Joint Ventures At December 31, 2024, we were engaged in nine active CCJV projects. Our proportionate share of the equity in these joint ventures was between 50.0% and 70.0%. During the years ended December 31, 2024, 2023 and 2022, total revenue from CCJVs was $349.5 million, $307.2 million and $437.1 million, respectively. During the years ended December 31, 2024, 2023 and 2022, CCJVs provided $69.8 million, and used $38.1 million and $5.7 million of operating cash flows, respectively. As of December 31, 2024, our share of revenue remaining to be recognized on these CCJVs was $337.7 million and ranged from $1.9 million to $132.9 million by project. Unconsolidated Construction Joint Ventures As discussed in Note 1, where we have determined we are not the primary beneficiary of a joint venture but do exercise significant influence, we account for our share of the operations of unconsolidated construction joint ventures on a pro rata basis in revenue and cost of revenue in the consolidated statements of operations and in equity in construction joint ventures or accrued expenses and other current liabilities in the consolidated balance sheets. As of December 31, 2024, we were engaged in five active unconsolidated construction joint venture projects. Our proportionate share of the equity in these unconsolidated construction joint ventures ranged from 30.0% to 50.0%. As of December 31, 2024, our share of the revenue remaining to be recognized on these unconsolidated construction joint ventures was $26.1 million and ranged from $0.4 million to $21.3 million by project.

2024 Annual Report F-33 10. Investments in Affiliates Our investments in affiliates balance is related to our investments in unconsolidated non-construction entities that we account for using the equity method of accounting, including investments in foreign affiliates, real estate ventures and an asphalt terminal entity. The foreign affiliates in which we are invested are engaged in mineral drilling services and the manufacture and supply of drilling equipment, parts and supplies in Latin America. The real estate ventures were formed to accomplish specific real estate development projects in which our wholly owned subsidiary, Granite Land Company, participates with third-party partners. The asphalt terminal entity is a 50% interest in a limited liability company which owns and operates an asphalt terminal and operates an emulsion plant in Nevada. We have determined that the real estate ventures are not consolidated because although they are VIEs, we are not the primary beneficiary. We have determined that the foreign affiliates and the asphalt terminal entity are not consolidated because they are not VIEs and we do not hold the majority voting interest. As such, these entities are accounted for using the equity method. Our investments in affiliates balance consists of equity method investments in the following types of entities: (in thousands) December 31, 2024 December 31, 2023 Foreign $ 72,075 $ 68,407 Real estate 4,552 7,136 Asphalt terminal 17,404 17,367 Total investments in affiliates $ 94,031 $ 92,910 The following table provides summarized balance sheet information for our affiliates accounted for under the equity method on a combined basis: (in thousands) December 31, 2024 December 31, 2023 Current assets $ 205,235 $ 204,897 Noncurrent assets 130,451 159,694 Total assets $ 335,686 $ 364,591 Current liabilities $ 68,679 $ 81,899 Long-term liabilities(1) 45,007 54,591 Total liabilities $ 113,686 $ 136,490 Net assets $ 222,000 $ 228,101 Granite’s share of net assets $ 94,031 $ 92,910 (1) This balance is primarily related to local bank debt for equipment purchases, working capital in our foreign affiliates and debt associated with our real estate investments. Of the $335.7 million in total assets as of December 31, 2024, we had investments in two real estate ventures with total assets of $29.9 million and $5.3 million, our foreign affiliates had total assets of $258.3 million, and the asphalt terminal entity had total assets of $42.2 million. As of December 31, 2024 and 2023, all of the equity method investments in real estate ventures were in residential real estate in Texas and California. As of December 31, 2024, our percent ownership in the real estate ventures ranged from 10% to 25%. We have direct and indirect investments in our foreign affiliates, and our percent ownership in foreign affiliates ranged from 25% to 50% as of December 31, 2024.

As discussed in Note 1, we have asset retirement obligations, which are liabilities associated with our legally required obligations to reclaim owned and leased quarry property and related facilities. As of December 31, 2024 and 2023, $6.6 million and $5.8 million, respectively, of our asset retirement obligations were included in accrued expenses and other current liabilities and $37.8 million and $32.7 million, respectively, were included in other long-term liabilities in the consolidated balance sheets. Of the amount included in other long-term liabilities as of December 31, 2024, $5.9 million is expected to be settled in 2026, $8.2 million in 2027, $1.2 million in 2028, $3.4 million in 2029 and the remaining $19.1 million is expected to be settled thereafter.

2024 Annual Report F-35 12. Intangible Assets Indefinite-lived Intangible Assets Indefinite-lived intangible assets primarily consist of goodwill. The following table presents the goodwill balance by reportable segment: (in thousands) December 31, 2024 December 31, 2023 Construction $ 134,977 $ 130,569 Materials 79,488 24,435 Total goodwill $ 214,465 $ 155,004 During 2024, total goodwill increased by approximately $67.9 million related to the acquisition of D&B. This increase was partially offset by a decrease of $8.1 million in goodwill as a result of our finalization of the LRC/MSG acquisition purchase price allocation in the third quarter of 2024. See Note 2 for additional information. Identifiable Intangible Assets As of December 31, 2024 and 2023, net identifiable intangible assets were $127.9 million and $117.2 million, respectively, net of accumulated amortization of $38.9 million and $24.8 million, respectively. The intangible assets balances in the consolidated balance sheets as of December 31, 2024 and 2023 also included an immaterial amount of indefinite-lived intangible assets. The increase in the 2024 identifiable intangible assets balance was primarily related to the D&B acquisition (see Note 2) which contributed $27.9 million of identifiable intangible assets. Of this, $18.2 million were customer relationship intangibles. The net amortization expense related to identifiable intangible assets for each of the years ended December 31, 2024, 2023 and 2022 was $14.1 million, $2.3 million and $2.0 million, respectively, and was primarily included in cost of revenue in the consolidated statements of operations. Amortization expense based on the identifiable intangible assets balance at December 31, 2024 is expected to be $9.4 million in 2025, $9.0 million in 2026, $8.6 million in 2027, $8.4 million in 2028, $8.4 million in 2029 and $84.1 million thereafter. 13.

F-36 Granite Construction Incorporated 14. Long-Term Debt (in thousands) December 31, 2024 December 31, 2023 3.25% Convertible Notes due 2030 $ 373,750 $ — 3.75% Convertible Notes due 2028 373,750 373,750 2.75% Convertible Notes — 31,338 Credit Agreement—Term Loan — 150,000 Credit Agreement—Revolver — 100,000 Debt issuance costs and other (8,452) (375) Total debt $ 739,048 $ 654,713 Less: current maturities 1,109 39,932 Total long-term debt $ 737,939 $ 614,781 Credit Agreement In June 2022, we entered into the Credit Agreement which matures on June 2, 2027. The Credit Agreement consisted of a $350.0 million senior secured, five-year revolving credit facility (the “Revolver”), including an accordion feature allowing us to increase borrowings up to the greater of (a) $200.0 million and (b) 100% of twelve-month trailing consolidated EBITDA, subject to lender approval. The Credit Agreement includes a $150.0 million sublimit for letters of credit ($75.0 million for financial letters of credit) and a $20.0 million sublimit for swingline loans. In May 2023, we entered into Amendment No. 1 to the Credit Agreement (“Amendment No. 1”). Amendment No. 1 amended the Credit Agreement to, among other things, permit us to exchange our 2.75% Convertible Notes for cash and shares of our common stock and to clarify that (i) the issuance of the 3.75% Convertible Notes was permitted under the terms of the Credit Agreement and (ii) that a Swap Contract (as defined in the Credit Agreement) does not include any Permitted Call Spread Transaction (as defined in the Credit Agreement). In November 2023, we entered into Amendment No. 2 to the Credit Agreement (“Amendment No. 2”) which amended the Credit Agreement to, among other things, provide for a $150.0 million senior secured term loan (the “Term Loan”), which was fully drawn on closing to fund the LRC/MSG acquisition. The Term Loan was scheduled to mature on June 2, 2027 and amortize 5% per year, payable in quarterly installments beginning in the first quarter of 2024. The Term Loan was fully repaid with the net proceeds from our 3.25% Convertible Notes in the second quarter of 2024. We may borrow on the Revolver, at our option, at either (a) the Secured Overnight Financing Rate (“SOFR”) term rate plus a credit adjustment spread plus applicable margin ranging from 1.0% to 2.0%, or (b) a base rate plus an applicable margin ranging from zero to 1.0%. The applicable margin is based on our Consolidated Leverage Ratio (as defined in our Credit Agreement), calculated quarterly. As of December 31, 2024, the total unused availability under the Credit Agreement was $333.7 million, resulting from $16.3 million in issued and outstanding letters of credit and no amount drawn under the Revolver. The letters of credit had expiration dates between March 2025 and November 2025. 3.25% Convertible Notes On June 11, 2024, we issued $373.8 million aggregate principal amount of our 3.25% Convertible Notes. The 3.25% Convertible Notes bear interest at a rate of 3.25% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on December 15, 2024. The 3.25% Convertible Notes mature on June 15, 2030, unless earlier converted, redeemed or repurchased. Prior to the close of business on the business day immediately preceding December 15, 2029, the 3.25% Convertible Notes will be convertible at the option of the holders only upon the occurrence of certain events and during certain periods. Thereafter, the 3.25% Convertible Notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding their maturity date. GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-37 The 3.25% Convertible Notes have an initial conversion rate of 12.8398 shares of our common stock per $1,000 principal amount of the 3.25% Convertible Notes, which is equivalent to an initial conversion price of approximately $77.88 per share of our common stock, subject to adjustment if certain events occur. Upon conversion, we will settle the principal amount of the 3.25% Convertible Notes in cash, and any conversion premium in excess of the principal amount in cash, or a combination of cash and shares of common stock, at our election. In addition, upon the occurrence of a “fundamental change” as defined in the indenture governing the 3.25% Convertible Notes, holders may require us to repurchase for cash all or any portion of their 3.25% Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 3.25% Convertible Notes to be repurchased plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. If certain corporate events that constitute a “make- whole fundamental change” as set forth in the indenture governing the 3.25% Convertible Notes occur prior to the maturity date of the 3.25% Convertible Notes or if we deliver a notice of redemption, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its 3.25% Convertible Notes in connection with such event or notice of redemption. We will not be able to redeem the 3.25% Convertible Notes prior to June 21, 2027. On or after June 21, 2027, we will be able to redeem for cash all or any portion of the 3.25% Convertible Notes, at our option, if the last reported sale price of Granite’s common stock is equal to or greater than 130% of the conversion price for a specified period of time at a redemption price equal to 100% of the principal amount of the 3.25% Convertible Notes to be redeemed, plus accrued but unpaid interest to, but excluding, the redemption date. The indenture governing the 3.25% Convertible Notes contains customary events of default. In the case of an event of default arising from certain events of bankruptcy, insolvency or reorganization, with respect to us or our significant subsidiaries, all outstanding 3.25% Convertible Notes will become due and payable immediately without further action or notice. If any other event of default occurs and is continuing, then the trustee or the holders of at least 25% in aggregate principal amount of the 3.25% Convertible Notes then outstanding may declare the 3.25% Convertible Notes due and payable immediately. The net proceeds from the sale of the 3.25% Convertible Notes were approximately $365.0 million, after deducting the initial purchasers’ discount. We used approximately $46.0 million of the net proceeds from the 3.25% Convertible Notes offering to pay the cost of entering into capped call transactions in connection with the 3.25% Convertible Notes. In addition, we paid approximately $57.6 million of the net proceeds from the 3.25% Convertible Notes offering to repurchase approximately $30.2 million in aggregate principal amount of our 2.75% Convertible Notes in separate and individually negotiated transactions entered into concurrently with the pricing of the offering; repaid amounts outstanding under our Term Loan of $148.1 million; repurchased $13.3 million of shares under our authorized share repurchase program; with the remainder of the net proceeds available for general corporate purposes, which may include acquisitions. 2024 Capped Call Transactions In June 2024, we entered into privately negotiated capped call transactions in connection with the offering of the 3.25% Convertible Notes (the “2024 capped call transactions”). The 2024 capped call transactions are expected generally to reduce the potential dilution to our common stock upon any conversion of the 3.25% Convertible Notes and/or offset any cash payments we are required to make in excess of the principal amount of converted 3.25% Convertible Notes, as the case may be. If, however, the market price per share of our common stock, as measured under the terms of the 2024 capped call transactions, exceeds the cap price of $119.82 of the 2024 capped call transactions, there would nevertheless be dilution and/or there would not be an offset of such cash payments, in each case, to the extent that such market price exceeds the cap price of the 2024 capped call transactions. 3.75% Convertible Notes On May 11, 2023, we issued $373.8 million aggregate principal amount of our 3.75% Convertible Notes. The 3.75% Convertible Notes bear interest at a rate of 3.75% per annum payable semiannually in arrears on May 15 and November 15 of each year, beginning on November 15, 2023 and mature on May 15, 2028, unless earlier converted, redeemed or repurchased. Prior to the close of business on the business day immediately preceding November 15, 2027, the 3.75% Convertible Notes will be convertible at the option of the holders only upon the occurrence of certain events and during certain periods. Thereafter, the 3.75% Convertible Notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding the maturity date.

F-38 Granite Construction Incorporated The initial conversion rate applicable to the 3.75% Convertible Notes is 21.6807 shares of our common stock per $1,000 principal amount of the 3.75% Convertible Notes, which is equivalent to an initial conversion price of approximately $46.12 per share of our common stock, subject to adjustment if certain events occur. Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. In addition, upon the occurrence of a “fundamental change” as defined in the indenture governing the 3.75% Convertible Notes, holders may require us to repurchase for cash all or any portion of their 3.75% Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 3.75% Convertible Notes to be repurchased plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. If certain corporate events that constitute a “make-whole fundamental change” as set forth in the indenture governing the 3.75% Convertible Notes occur prior to the maturity date of the 3.75% Convertible Notes or if we deliver a notice of redemption, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its 3.75% Convertible Notes in connection with such event or notice of redemption. We will not be able to redeem the 3.75% Convertible Notes prior to May 20, 2026. On or after May 20, 2026, we have the option to redeem for cash all or any portion of the 3.75% Convertible Notes if the last reported sale price of our common stock is equal to or greater than 130% of the conversion price for a specified period of time at a redemption price equal to 100% of the principal amount of the 3.75% Convertible Notes to be redeemed, plus any accrued but unpaid interest to, but excluding, the redemption date. The indenture governing the 3.75% Convertible Notes contains customary events of default. In the case of an event of default arising from certain events of bankruptcy, insolvency or reorganization, with respect to us or our significant subsidiaries, all outstanding 3.75% Convertible Notes will become due and payable immediately without further action or notice. If any other event of default occurs and is continuing, then the trustee or the holders of at least 25% in aggregate principal amount of the 3.75% Convertible Notes then outstanding may declare the 3.75% Convertible Notes due and payable immediately. The net proceeds from the sale of the 3.75% Convertible Notes were approximately $364.4 million after deducting the initial purchasers’ discount. We used approximately $53.0 million of the net proceeds from the offering to pay the cost of the 2023 capped call transactions (as described below). In addition, we used approximately $198.8 million of the net proceeds and issued 1,390,500 shares of Granite common stock in exchange for approximately $198.7 million aggregate principal amount of our 2.75% Convertible Notes concurrent with the offering in separate and individually negotiated transactions (the “Exchange Transaction”). In connection with the Exchange Transaction, we entered into partial unwind agreements (the “Unwind Agreements”) with certain financial institutions to unwind a portion of the convertible note hedge and warrant transactions entered into in connection with the offering of the 2.75% Convertible Notes. Pursuant to the Unwind Agreements, we received 1,390,516 shares of our common stock (and cash in lieu of any fractional shares) in respect of the unwind of the portion of the existing convertible note hedge transactions that correspond to the 2.75% Convertible Notes that were exchanged in the Exchange Transaction described above and paid $13.2 million in cash in respect of the unwind of the portion of the existing warrant transactions that correspond to the 2.75% Convertible Notes that were exchanged in the Exchange Transaction described above. 2023 Capped Call Transactions In May 2023, we entered into capped call transactions (the “2023 capped call transactions”) in connection with the offering of the 3.75% Convertible Notes. The 2023 capped call transactions are expected generally to reduce the potential dilution to our common stock upon conversion of the 3.75% Convertible Notes and/or offset any cash payments we are required to make in excess of the principal amount of converted 3.75% Convertible Notes, as the case may be. If, however, the market price per share of our common stock, as measured under the terms of the 2023 capped call transactions, exceeds the cap price of $79.83 of the 2023 capped call transactions, there would nevertheless be dilution and/or there would not be an offset of such cash payments, in each case, to the extent that such market price exceeds the cap price of the 2023 capped call transactions. 2.75% Convertible Notes The 2.75% Convertible Notes were issued in November 2019 in an aggregate principal amount of $230.0 million, with an interest rate of 2.75% and a maturity date of November 1, 2024, unless earlier converted, redeemed or repurchased. In June 2024, we called the 2.75% Convertible Notes for redemption. As of December 31, 2024, no 2.75% Convertible Notes remained outstanding.

2024 Annual Report F-39 Real Estate Indebtedness Our unconsolidated investments in real estate ventures are subject to mortgage indebtedness. This indebtedness is non-recourse to Granite but is recourse to the real estate venture. The terms of this indebtedness are typically renegotiated to reflect the evolving nature of the real estate project as it progresses through acquisition, entitlement, development and leasing. Modification of these terms may include changes in loan-to-value ratios requiring the real estate venture to repay portions of the debt. The debt associated with our unconsolidated non-construction entities is disclosed in Note 10. Covenants and Events of Default Our Credit Agreement requires us to comply with various affirmative, restrictive and financial covenants, including the financial covenants described below. Our failure to comply with these covenants would constitute an event of default under the Credit Agreement. Additionally, the 3.25% Convertible Notes and 3.75% Convertible Notes are governed by the terms and conditions of their respective indentures. Our failure to pay principal, interest or other amounts when due or within the relevant grace period on our 3.25% Convertible Notes, our 3.75% Convertible Notes or our Credit Agreement would constitute an event of default under the 3.25% Convertible Notes indenture, the 3.75% Convertible Notes indenture or the Credit Agreement. A default under our Credit Agreement could result in (i) us no longer being entitled to borrow under such facility; (ii) termination of such facility; (iii) the requirement that any letters of credit under such facility be cash collateralized; (iv) acceleration of amounts owed under the Credit Agreement; and/or (v) foreclosure on any collateral securing the obligations under such facility. A default under the 3.25% Convertible Notes indenture or the 3.75% Convertible Notes indenture could result in acceleration of the maturity of the notes. The most significant financial covenants under the terms of our Credit Agreement require the maintenance of a minimum Consolidated Interest Coverage Ratio and a maximum Consolidated Leverage Ratio. As of December 31, 2024, we were in compliance with all covenants contained in the Credit Agreement. We are not aware of any non-compliance by any of our unconsolidated real estate ventures with the covenants contained in their debt agreements. Debt Issuance Costs During the years ended December 31, 2024 and December 31, 2023, we capitalized $10.5 million and $10.9 million, respectively, in third party offering costs related to the issuance of the 3.25% Convertible Notes, 3.75% Convertible Notes and the Term Loan. Capitalized issuance costs are amortized over the life of the related debt. During the years ended December 31, 2024, 2023 and 2022, we recorded $3.9 million, $3.5 million and $2.5 million, respectively, of amortization related to debt issuance costs. The years ended December 31, 2024 and 2023 included an immaterial amount and $1.7 million, respectively, of accelerated amortization of debt issuance costs associated with the 2.75% Convertible Notes that were repaid and are included in the loss on debt extinguishment. 15. Leases We have leases for office and shop space, as well as for equipment primarily utilized in our construction projects. As of December 31, 2024, our lease contracts were primarily classified as operating leases and had terms ranging from month-to-month to 31 years. As of December 31, 2024 and 2023, right of use assets and long term lease liabilities were separately presented and short term lease liabilities of $20.2 million and $16.8 million, respectively, were included in accrued expenses and other current liabilities in our consolidated balance sheets. As of December 31, 2024, we had no lease contracts that had not yet commenced but created significant rights and obligations. Lease expense was $24.5 million, $21.4 million, $21.9 million for the years ended December 31, 2024, 2023 and 2022, respectively. As of December 31, 2024 and 2023 our weighted-average remaining lease term was 8.4 years and 9.4 years, respectively, and the weighted-average discount rate was 5.34% and 4.92%, respectively. As of December 31, 2024, the lease liability is equal to the present value of the remaining lease payments, discounted using the incremental borrowing rate on our secured debt, using one maturity discount rate that is updated quarterly, as it is not materially different than the discount rates applied to each of the leases in the portfolio.

Employee Benefit Plans Granite Construction Profit Sharing and 401(k) Plan The Granite Construction Profit Sharing and 401(k) Plan (the “401(k) Plan”) is a defined contribution plan covering all employees except employees covered by collective bargaining agreements and certain employees of our CCJVs, LRC/MSG and D&B. Our 401(k) matching contributions can be up to 6% of an employee’s gross pay at the discretion of the Board of Directors. Our 401(k) matching contributions to the 401(k) Plan for the years ended December 31, 2024, 2023 and 2022 were $20.0 million, $18.6 million, and $17.7 million, respectively. Profit sharing contributions from us may be made to the 401(k) Plan in an amount determined by the Board of Directors. We made no profit sharing contributions during the years ended December 31, 2024, 2023 and 2022. Lehman-Roberts/Memphis Stone & Gravel 401(k) Retirement Plan The Lehman-Roberts Company sponsors a defined contribution plan for the benefit of its employees. Matching contributions to this plan were immaterial for the year ended December 31, 2024, as well as the period between our acquisition of LRC/MSG (see Note 2) and December 31, 2023. This plan also covers the employees of D&B. Non-Qualified Deferred Compensation Plan We offer a Non-Qualified Deferred Compensation Plan (“NQDC Plan”) to a select group of our highly compensated employees and non-employee directors. The NQDC Plan provides participants the opportunity to defer payment of certain compensation as defined in the NQDC Plan. Our NQDC Plan obligations are funded through a Rabbi Trust which was fully funded as of December 31, 2024. The assets held by the Rabbi Trust at December 31, 2024 and 2023 are substantially in the form of Company-owned life insurance and are included in other noncurrent assets in the consolidated balance sheets. As of December 31, 2024, there were 68 active participants in the NQDC Plan. NQDC Plan obligations were $27.8 million and $25.2 million as of December 31, 2024 and 2023, respectively, and were primarily included in other long-term liabilities in the consolidated balance sheets. In addition, we had supplemental retirement benefits of $3.4 million and $3.7 million in other long-term liabilities in the consolidated balance sheets as of December 31, 2024 and 2023, respectively. Our significant obligations related to the NQDC Plan are $3.6 million in 2025, $2.5 million in 2026, $2.3 million in 2027, $2.2 million in 2028, $1.3 million in 2029 and $15.9 million thereafter.

2024 Annual Report F-41 Multi-employer Pension Plans As of December 31, 2024, three of our wholly-owned subsidiaries, Granite Construction Company, Layne Christensen Company and Granite Industrial, Inc. contribute to various multi-employer pension plans on behalf of union employees. The risks of participating in these multi-employer plans are different from single-employer plans in the following aspects: • Assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers. • If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. • If we chose to stop participating in some of the multi-employer plans, we may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability. The following table presents our participation in these plans (dollars in thousands): Pension Protection Act (“PPA”) Certified Zone Status(1) Expiration Date of Collective Bargaining Agreement(3) Pension Plan Employer Identification Number FIP/RP Status Pending/ Implemented(2) Contributions Surcharge ImposedPension Trust Fund 2024 2023 2024 2023 2022 Pension Trust Fund for Operating Engineers 94-6090764 Green Yellow Yes $ 10,972 $ 10,434 $ 9,783 No 3/31/2025 3/31/2026 6/30/2026 9/30/2026 1/31/2027 10/31/2027 Locals 302 and 612 IUOE-Employers Construction Industry Retirement Plan 91-6028571 Green Green No 6,976 6,520 5,204 No 3/31/2026 5/31/2028 Operating Engineers Pension Trust Fund 95-6032478 Green Green No 5,759 5,357 4,768 No 6/30/2025 All other funds (44 as of December 31, 2024) 22,105 20,466 18,270 Total contributions: $ 45,811 $ 42,777 $ 38,025 (1) The most recent PPA zone status available in 2024 and 2023 is for the plan’s year-end during 2023 and 2022, respectively. The zone status is based on information that we received from the plan and is certified by the plan’s actuary. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the orange zone are less than 80 percent funded and have an Accumulated Funding Deficiency in the current year or projected into the next six years, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded. (2) The “FIP/RP Status Pending/Implemented” column indicates plans for which a financial improvement plan (“FIP”) or a rehabilitation plan (“RP”) is either pending or has been implemented. (3) Lists the expiration date(s) of the collective-bargaining agreement(s) to which the plans are subject. Pension trust funds with a range of expiration dates have various collective bargaining agreements. Based upon the most recently available annual reports, our contribution to each of the individually significant plans listed in the table above was less than 5% of each plan’s total contributions. We currently have no intention of withdrawing from any of the multi-employer pension plans in which we participate that would result in a significant withdrawal liability. In addition, we do not have any significant future obligations or funding requirements related to these plans other than the ongoing contributions that are paid as hours are worked by plan participants.

F-42 Granite Construction Incorporated 17. Shareholders’ Equity Stock-based Compensation On June 2, 2021, our stockholders approved the 2021 Equity Incentive Plan (the “2021 Plan”), which replaced the Amended and Restated 2012 Equity Incentive Plan (the “2012 Plan”) and no further awards may be granted under the 2012 Plan. The 2021 Plan provides for the issuance of restricted stock, RSUs and stock options to eligible employees and to members of our Board of Directors. During the years ended December 31, 2024, 2023 and 2022, we did not grant any stock options or restricted stock awards and as of December 31, 2024, there were no stock options or restricted stock awards outstanding. On June 5, 2024, our stockholders approved the 2024 Equity Incentive Plan (the “2024 Plan”), which replaced the 2021 Plan and no further awards may be granted under the 2021 Plan. The 2024 Plan provides for the issuance of restricted stock, RSUs and stock options to eligible employees and to members of our Board of Directors. During the year ended December 31, 2024, we did not grant any stock options or restricted stock awards and as of December 31, 2024, there were no stock options or restricted stock awards outstanding. A total of 2,249,883 shares of our common stock were reserved for issuance under the 2024 Plan of which 2,211,325 remained available as of December 31, 2024. Restricted Stock Units RSUs are issued for compensatory purposes. RSU stock compensation cost is measured at our common stock’s fair value based on the market price at the date of grant. We recognize stock compensation cost only for RSUs that we estimate will ultimately vest. We estimate the number of shares that will ultimately vest at each grant date based on our historical experience and adjust stock compensation cost based on changes in those estimates over time. RSU stock compensation cost is recognized ratably over the shorter of the vesting period (generally ranging from immediate vesting to three years) or the period from grant date to the first date after the holder reaches age 62 and has completed certain specified years of service, when all RSUs become fully vested. Vesting of RSUs is not subject to any market or performance conditions and vesting provisions are at the discretion of the Compensation Committee. A recipient of RSUs may not sell or otherwise transfer unvested RSUs and, in the event a recipient’s employment or board service is terminated prior to the end of the vesting period, any unvested RSUs are surrendered to us, subject to limited exceptions. A summary of the changes in our RSUs during the years ended December 31, 2024, 2023 and 2022 is as follows (shares in thousands): Years Ended December 31, 2024 2023 2022 RSUs Weighted- Average Grant-Date Fair Value per RSU RSUs Weighted- Average Grant-Date Fair Value per RSU RSUs Weighted- Average Grant-Date Fair Value per RSU Outstanding, beginning balance 568 $ 37.05 568 $ 31.64 553 $ 30.09 Granted 394 55.57 315 40.86 311 31.70 Vested (399) 45.84 (289) 30.83 (263) 28.98 Forfeited (16) 42.63 (27) 36.09 (33) 28.21 Outstanding, ending balance 546 $ 43.97 568 $ 37.05 568 $ 31.64 Compensation cost related to RSUs was $19.6 million ($14.5 million net of statutory tax rate), $10.5 million ($7.8 million net of statutory tax rate), and $7.5 million ($5.6 million net of statutory tax rate) for the years ended December 31, 2024, 2023 and 2022, respectively. The grant date fair value of RSUs vested during the years ended December 31, 2024, 2023 and 2022 was $18.3 million, $8.9 million and $7.6 million, respectively. As of December 31, 2024, there was $10.6 million of unrecognized compensation cost related to RSUs which will be recognized over a remaining weighted-average period of 1.4 years.

2024 Annual Report F-43 401(k) Plan As of December 31, 2024, the 401(k) Plan owned 634,808 shares of our common stock. Dividends on shares held by the 401(k) Plan are charged to retained earnings and all shares held by the 401(k) Plan are treated as outstanding in computing our earnings per share. Share Repurchase Program As announced on February 3, 2022, on February 1, 2022, the Board of Directors authorized us to purchase up to $300.0 million of our common stock at management’s discretion. During the year ended December 31, 2024, we repurchased 524,800 shares for $42.0 million under this authorization. As of December 31, 2024, $189.5 million of the authorization remained available. The specific timing and amount of any future repurchases will vary based on market conditions, securities law limitations and other factors. 18. Weighted Average Shares Outstanding and Net Income Per Share The following table presents a reconciliation of net income and the weighted average shares of common stock used in calculating basic and diluted net income per share as well as the calculation of basic and diluted net income per share. Years Ended December 31, 2024 2023 2022 Numerator Net income attributable to common shareholders for basic earnings per share $126,346 $43,599 $ 83,302 Add: Interest expense, net of tax, related to Convertible Notes (1) 11,472 7,622 5,890 Net income attributable to common shareholders for diluted earnings per share $137,818 $51,221 $ 89,192 Denominator Weighted average common shares outstanding, basic 43,846 43,879 44,485 Add: Dilutive effect of RSUs 565 583 532 Add: Dilutive effect of Convertible Notes(1) 8,103 8,103 7,309 Weighted average common shares outstanding, diluted 52,514 52,565 52,326 Net income per share, basic $ 2.88 $ 0.99 $ 1.87 Net income per share, diluted $ 2.62 $ 0.97 $ 1.70 (1) The dilutive effect of the convertible notes was determined using the if-converted method. As the 3.75% Convertible Notes will be convertible into cash, shares of our common stock or a combination thereof at our election, the 3.75% Convertible Notes are assumed to be converted into common stock at the beginning of the reporting period, and the resulting shares are included in the denominator of the calculation. In addition, interest charges, net of any income tax effects are added back to the numerator of the calculation. For the 3.25% Convertible Notes, we are required to settle the principal amount in cash and any conversion premium in excess of the principal amount in cash, shares of common stock, or a combination of cash and shares of common stock, at our election. As such, the 3.25% Convertible Notes only have an impact on diluted earnings per share when the average share price of our common stock exceeds the conversion price. The 2.75% Convertible Notes will be convertible into cash, shares of our common stock or a combination thereof at our election. The shares associated with the 2.75% Convertible Notes were not included in our calculation of diluted net income per share for the year ended December 31, 2023 because their effect would have been anti-dilutive. The number of shares used in calculating diluted net income per share for the year ended December 31, 2022 includes the dilutive effect of the 2.75% Convertible Notes. In connection with the issuance of the 3.25% Convertible Notes and 3.75% Convertible Notes, we entered into the 2024 capped call transactions and 2023 capped call transactions, respectively, which were not included for purposes of calculating the number of diluted shares outstanding, as their effect would have been anti-dilutive.

2024 Annual Report F-45 The following is a summary of the deferred tax assets and liabilities: (in thousands) December 31, 2024 December 31, 2023 Deferred tax assets: Receivables $ 1,270 $ 1,328 Insurance 15,307 15,018 Deferred compensation 11,884 10,424 Convertible debt—capped call amortization 19,852 11,963 Accrued compensation 5,048 3,811 Other accrued liabilities 2,073 1,218 Contract income recognition 16,822 16,986 Lease liabilities 19,678 16,272 Net operating loss carryforwards 29,182 40,541 Valuation allowance (23,450) (24,569) Other 4,199 3,587 Total deferred tax assets 101,865 96,579 Deferred tax liabilities: Property and equipment 96,908 76,067 Right of use assets 18,831 16,041 Total deferred tax liabilities 115,739 92,108 Net deferred tax assets (liabilities) $ (13,874) $ 4,471 The following is a summary of the net operating loss carryforwards at December 31, 2024: (in thousands) Expiration Gross Carryforward Tax Effected Carryforward Federal net operating loss carryforwards N/A $ 10,793 $ 2,267 State net operating loss carryforwards 2025–2044 $ 238,153 11,005 Foreign tax loss carryforwards 2025–2044 $ 54,135 15,910 Total net operating loss carryforwards $ 29,182 The federal, state and foreign net operating loss carryforwards above include unrecognized tax benefits taken in prior years and the net operating loss carryforward deferred tax asset is presented net of these unrecognized tax benefits in accordance with ASC Topic 740, Income Taxes. The federal and state net operating losses acquired during the Layne Christensen Company acquisition in 2018 are subject to Internal Revenue Code Section 382 limitations and may be limited in future periods and a portion may expire unused. As we expect to use the federal net operating loss carryforwards prior to expiration we believe that it is more likely than not that these deferred tax assets will be realized and no valuation allowance was deemed necessary. We have provided a valuation allowance on the net operating loss deferred tax asset or the net deferred tax assets for certain foreign, state and local jurisdictions because we do not believe it is more likely than not that they will be realized. The following is a summary of the change in valuation allowance: (in thousands) December 31, 2024 December 31, 2023 Beginning balance $ 24,569 $ 19,919 Additions (deductions), net (1,119) 4,650 Ending balance $ 23,450 $ 24,569 GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

F-46 Granite Construction Incorporated The change in the valuation allowance in 2024 is mainly due to the reversal of valuation allowances related to the utilization of state and local net operating loss carryforwards and a decrease in net deferred tax assets associated with our foreign operations which we do not believe are more likely than not to be used in future years. We intend to indefinitely reinvest certain earnings of our foreign subsidiaries and affiliates. There are generally no federal income taxes on dividends from foreign subsidiaries therefore we would only be subject to other taxes, such as withholding and local taxes, upon distribution of these earnings. We have $54.4 million of accumulated undistributed earnings that we consider indefinitely reinvested as of December 31, 2024. It is not practicable to determine the amount of taxes that would be payable upon remittance of these earnings. Deferred foreign withholding taxes have been provided on undistributed earnings of certain foreign subsidiaries and foreign affiliates where the earnings are not considered to be invested indefinitely. Uncertain tax positions We file income tax returns in the U.S. and various state and local jurisdictions. We are currently under examination by various state taxing authorities for various tax years. We do not anticipate that any of these audits will result in a material change in our financial position. We are no longer subject to U.S. federal examinations by tax authorities for years before 2021 except for the 2018 tax year. With few exceptions, as of December 31, 2024, we are no longer subject to state examinations by taxing authorities for years before 2018. We file income tax returns in foreign jurisdictions where we operate. The returns are subject to examination which may be ongoing at any point in time and tax liabilities are recorded based on estimates of additional taxes which will be due upon settlement of those examinations. The tax years subject to examination by foreign tax authorities vary by jurisdiction, but generally we are no longer subject to examinations by taxing authorities for years before 2016. We had approximately $22.4 million and $22.6 million of total gross unrecognized tax benefits as of December 31, 2024 and 2023, respectively. There were approximately $5.2 million and $5.5 million of unrecognized tax benefits that would affect the effective tax rate in any future period at December 31, 2024 and 2023, respectively. It is reasonably possible that our unrecognized tax benefit could decrease by approximately $1.2 million in 2025, which would impact our effective tax rate in 2025. The decrease relates to anticipated statute expirations and anticipated resolution of outstanding unrecognized tax benefits. The following is a tabular reconciliation of unrecognized tax benefits (in thousands). The balances in the reconciliation are the gross amounts before considering reductions related to available net operating losses. The balance of unrecognized tax benefits net of available net operating losses is included in other long-term liabilities and accrued expenses and other current liabilities in the consolidated balance sheets: December 31, 2024 2023 2022 Beginning balance $ 22,591 $ 22,756 $ 22,724 Gross increases—current period tax positions — — — Gross decreases—current period tax positions — — — Gross increases—prior period tax positions — — — Gross decreases—prior period tax positions (162) 77 (426) Settlements with taxing authorities/lapse of statute of limitations (70) (242) (60) Reclassification of balances from held for sale — — 518 Ending balance $ 22,359 $ 22,591 $ 22,756 GRANITE CONSTRUCTION INCORPORATED Notes to the Consolidated Financial Statements (Continued)

2024 Annual Report F-47 20. Contingencies—Legal Proceedings Liabilities relating to legal proceedings and government inquiries, to the extent that we have concluded such liabilities are probable and the amounts of such liabilities are reasonably estimable, are recorded in the consolidated balance sheets. It is possible that future developments in our legal proceedings and inquiries could require us to (i) adjust or reverse existing accruals, or (ii) record new accruals that we did not originally believe to be probable or that could not be reasonably estimated. Such changes could be material to our financial condition, results of operations and/or cash flows in any particular reporting period. In addition, disclosure is required when a material loss is probable but not reasonably estimable, a material loss is reasonably possible but not probable, or when it is reasonably possible that the amount of a loss will exceed the amount recorded. The total liabilities for legal proceedings were immaterial as of December 31, 2024 and 2023. The total range of possible loss related to (i) matters considered reasonably possible, and (ii) reasonably possible amounts in excess of accrued losses recorded for probable loss contingencies, including those related to liquidated damages, could have a material impact on our consolidated financial statements if they become probable and the reasonably estimable amount is determined. Ordinary Course Legal Proceedings In the ordinary course of business, we and our affiliates are involved in various legal proceedings alleging, among other things, liability issues or breach of contract or tortious conduct in connection with the performance of services and/or materials provided, the various outcomes of which often cannot be predicted with certainty. For information on our accounting policies regarding affirmative claims and back charges that we are party to in the ordinary course of business, see Note 1. We and our affiliates are also subject to government inquiries in the ordinary course of business seeking information concerning our compliance with government construction contracting requirements and various laws and regulations, the outcomes which often cannot be predicted with certainty. Some of the matters in which we or our joint ventures and affiliates are involved may involve compensatory, punitive, or other claims or sanctions that, if granted, could require us to pay damages or make other expenditures in amounts that are not probable to be incurred or cannot currently be reasonably estimated. In addition, in some circumstances our government contracts could be terminated, we could be suspended, debarred or incur other administrative penalties or sanctions, or payment of our costs could be disallowed. While any of our pending legal proceedings may be subject to early resolution as a result of our ongoing efforts to resolve the proceedings, whether or when any legal proceeding will be resolved is neither predictable nor guaranteed. 21. Reportable Segment Information We manage our operations under two reportable segments, Construction and Materials, which are distinguished by differences in business activities. Our reportable segments are the same as our operating segments and correspond with how our chief operating decision maker, or decision-making group (our “CODM”) regularly reviews financial information to allocate resources and assess performance. We identified our CODM as our Chief Executive Officer and our Chief Operating Officer. The Construction segment focuses on construction and rehabilitation of roads, pavement preservation, bridges, rail lines, airports, marine ports, dams, reservoirs, aqueducts, infrastructure and site development for use by the general public and water-related construction for municipal agencies, commercial water suppliers, industrial facilities and energy companies. It also provides construction of various complex projects including infrastructure / site development, mining, public safety, tunnel, solar, battery storage and other power-related projects. The Materials segment focuses on production of aggregates, asphalt concrete, liquid asphalt and recycled materials production for internal use in our construction projects and for sale to third parties. The accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies (see Note 1). In connection with our adoption of ASU 2023-07, Segment Reporting—Improvements to Reportable Segment Disclosures (see Note 1), we have enhanced our segment disclosures about significant segment expenses. Our CODM evaluates segment performance and makes business decisions based on operating income, which excludes non-operating income or expense. Segment assets include property and equipment, intangibles, goodwill, inventory and equity in construction joint ventures.

Granite Construction Incorporated Non-GAAP Financial Information The tables below contain financial information calculated other than in accordance with U.S. generally accepted accounting principles (“GAAP”). Specifically, management believes that non-GAAP financial measures such as EBITDA and EBITDA margin are useful in evaluating operating performance and are regularly used by securities analysts, institutional investors and other interested parties, and that such supplemental measures facilitate comparisons between companies that have different capital and financing structures and/or tax rates. We are also providing adjusted EBITDA and adjusted EBITDA margin, non-GAAP measures, to indicate the impact of a loss on debt extinguishment in 2023 and 2024, stock-based compensation expense and other costs, net, which include legal fees for the defense of a former Company officer in his ongoing civil litigation with the Securities and Exchange Commission, reorganization costs, strategic acquisition and divestiture expenses and non-cash impairment charges. In addition to the aforementioned costs, 2023 also included a litigation charge and 2022 include a gain on sale of a business. We also provide materials segment cash gross profit to exclude the impact of the segment’s depreciation, depletion and amortization from the segment’s gross profit. Management believes that non-GAAP financial measures such as materials segment cash gross profit are useful in evaluating operating performance and are regularly used by securities analysts, institutional investors and other interested parties, and that such supplemental measures facilitate comparisons between companies that have different capital and financing structures. Management believes that these additional non-GAAP financial measures facilitate comparisons between industry peer companies, and management uses these non-GAAP financial measures in evaluating the Company’s performance. However, the reader is cautioned that any non-GAAP financial measures provided by the Company are provided in addition to, and not as alternatives for, the Company’s reported results prepared in accordance with GAAP. Items that may have a significant impact on the Company’s financial position, results of operations and cash flows must be considered when assessing the Company’s actual financial condition and performance regardless of whether these items are included in non-GAAP financial measures. The methods used by the Company to calculate its non-GAAP financial measures may differ significantly from methods used by other companies to compute similar measures. As a result, any non-GAAP financial measures provided by the Company may not be comparable to similar measures provided by other companies. GRANITE CONSTRUCTION INCORPORATED
