## Notice of the 2026 Annual Meeting of Stockholders
**March 20, 2026**

**TO OUR STOCKHOLDERS:**

|:---|:---|
| The 2026 Annual Meeting of Stockholders of Primoris Services Corporation, a Delaware corporation, will be held virtually on Thursday, April 30, 2026, at 9:00 a.m., Central Time.<br>Only stockholders that owned shares of our Common Stock at the close of business on March 9, 2026, are entitled to vote at the Annual Meeting. A list of our stockholders will be made available at our principal executive offices at 2300 N. Field Street, Suite 1900, Dallas, Texas 75201 during ordinary business hours for ten days prior to the Annual Meeting. The list will also be available for the duration of the virtual meeting via a secure link provided to stockholders who register to attend the virtual meeting.<br>At the Annual Meeting, we will consider the following proposals, which are described in detail in the accompanying Proxy Statement:<br>**1.**<br>to elect eight Directors to hold office for a one-year term expiring at the Annual Meeting of Stockholders to be held in 2027 or until a successor is qualified and elected;<br>**2.**<br>to approve, in an advisory, non-binding vote, the Company's named executive officer compensation;<br>**3.**<br>to ratify the appointment of Baker Tilly US, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026; and<br>**4.**<br>to transact such other business as may properly come before the Annual Meeting and all adjournments or postponements thereof.<br>**Attending the Annual Meeting Virtually**<br>We have created and implemented the virtual format in order to facilitate stockholder attendance and participation by enabling stockholders to participate fully, and equally, from any location around the world, at no cost. A virtual Annual Meeting makes it possible for more stockholders (regardless of size, resources or physical location) to have direct access to information more quickly, while saving the Company and our stockholders time and money. We also believe that the online tools we have selected will increase stockholder communication. For example, the virtual format allows stockholders to communicate with us during the Annual Meeting so they can ask questions of our Board of Directors or management. During the live Q&A session of the Annual Meeting, we may answer questions as they come in to the extent relevant to the business of the Annual Meeting, as time permits.<br>Both stockholders of record and stockholders who hold their shares in "street name" will need to register to be able to attend the Annual Meeting via live audio webcast, submit their questions, and vote their shares electronically at the Annual Meeting by following the instructions below. Questions by stockholders can also be submitted via the meeting website in advance of the Annual Meeting, in addition to during the Annual Meeting. | <br>![Graphic](prim-20260430xdef14a_a005.gif)<br>**WHEN IS THE MEETING?**<br>Thursday, April 30, 2026,<br>at 9:00 a.m., Central Time |

**Proxy Statement Summary**

### 2025 Business Highlights
&nbsp;&nbsp;Primoris achieved record highs for annual revenue, earnings, and backlog in 2025. This is a testament to the strength of our end markets, customer relationships and employee prioritization of safe, quality execution. The demand for infrastructure solutions remains significant and the Company continued to invest in equipment and people in 2025, including purchasing $75.8 million in construction equipment and increasing employee headcount by 2,810 from year end 2024.<br>In the Utilities segment, revenue and backlog both increased double-digits for the year. The revenue growth was driven by better than anticipated activity in gas operations and continued strength in power delivery and communications. Gross margins in the Utilities segment continued to see improvement due to productivity improvements in power delivery and solid growth in gas operations and communications. Power delivery contract renewals and rising demand led to Master Services Agreement ("MSA") backlog of $7.0 billion as we continue to see market activity accelerate to upgrade, expand, and maintain the electric grid.<br>Energy segment revenues increased by almost 25%, driven primarily by growth in our renewables business. Natural gas generation was another key contributor to growth in the segment in 2025 as power demand continued to accelerate. Although gross profit increased in 2025, gross margins declined from the prior year, primarily due to lower margins on certain renewables projects.<br>The Company's full year net income was $274.9 million, or $5.02 per fully diluted share, an increase of 52% from 2024 driven by higher operating income and lower interest expense due to lower average debt balances and lower interest rates. We also generated cash flow from operations of more than $470 million and bolstered our balance sheet by reducing our long-term debt by nearly $330 million.<br>

### Corporate Responsibility Highlights
Primoris Services Corporation ("Primoris" or the "Company") believes that proactive oversight of Corporate Responsibility matters can improve a company's internal performance as well as have a positive impact on its relationship with all stakeholders—employees, customers, investors, suppliers, and communities.

In 2023 Primoris conducted a Materiality Assessment<sup>(1)</sup> to ascertain what Corporate Responsibility topics are the most important to our stakeholders and our business.

The purpose of the materiality assessment is to engage internal and external stakeholders on corporate responsibility topics. The findings allow Primoris to focus on the most meaningful Corporate Responsibility initiatives that will provide maximum impact to the Company's constituents.

The assessment consisted of three phases: 1) benchmarking, analysis of trends and identification of topics and definitions; 2) interviews with key stakeholders and 3) in-depth analysis and summary of findings.

The list of 20 topics were identified by reviewing peer materiality assessments and sustainability reports, emerging topics, leading Corporate Responsibility reporting frameworks, topics raised as important to stakeholders through other formal and informal engagements, the Company's Corporate Responsibility strategy and reporting, and topics raised by internal subject matter experts.

The stakeholders engaged were our Board of Directors, executive management team, employees, customers, investors, and suppliers.

Focusing on employee programs that address wellness, prosperity and quality of life creates a rewarding, engaging and inclusive workplace.<br>**Safety, Health and Wellness.** We are committed to the health, safety and wellness of our employees, and we pride ourselves on above average workplace safety. We track and maintain several key safety metrics, which senior management reviews monthly, and we evaluate management on their ability to provide safe working conditions on job sites and to create a strong safety culture. Lost Time Injury Rate ("LTIR") tracks the rate of injuries in the workplace which results in the employee having to take a minimum of one full working day away from work. For the year ended December 31, 2025, our LTIR rate was 0.11 compared to an industry average of 0.90 per the U.S. Bureau of Labor construction industry statistics. Total Recordable Incident Rate ("TRIR") tracks the total number of workplace injuries which rise to the level of the Occupational Safety and Health Administration's definition of recordability, whether leading to time away from work or not. TRIR is reported as the number of workplace safety incidents per 100 full-time workers during a one-year period. For the year ended December 31, 2025, our TRIR rate was 0.53 compared to an industry average of 2.20 per the U.S. Bureau of Labor construction industry statistics.<br>**Founding Member ET&D.** Focused on improving safety for Electric Line Workers through Electrical Transmission & Distribution Partnership (formal collaboration of industry stakeholders and the Occupational Safety & Health Administration)<br>**Mental Health Care.** Our employees have 24/7/365 access to free, confidential, mental healthcare assistance from licensed clinicians to help resolve work-related pressures, depression, stress, anxiety, grief, relationship problems, substance use or other emotional health concerns. To mitigate the risks of job burnout, employees are encouraged to take their well-earned vacation to spend time with their families, enjoy recreational activities and rest.<br>**Compensation and Benefits.** As part of our compensation philosophy, we believe that we must offer and maintain market competitive total rewards programs for our employees in order to attract and retain superior talent. Our compensation programs are generally designed to align employee compensation with market practices and our performance. With respect to our executive officers, business unit management, and other senior leadership, compensation programs consist of both fixed and variable components. The fixed portion is generally set at market levels, with variable compensation designed to reward employees based on company and individual performance. In connection with these compensation programs, we grant stock-based compensation to management and key personnel at the business unit levels, which we believe helps to align incentives throughout our organization. | **0.11** <br>Lost Time Injury Rate ("LTIR")<br>**0.53** <br>Total Recordable <br>Incident Rate ("TRIR")<br>![Graphic](prim-20260430xdef14a_a033.jpg)<br>**7** <br>Employee resource <br>groups including <br>Primoris Veterans<br>![Graphic](prim-20260430xdef14a_a034.jpg) |

| &nbsp;&nbsp;&nbsp;&nbsp;A governance refresh undertaken in 2025 included publication of our Corporate Governance Guidelines dated December 2025, Audit Committee Charter dated May 2025 and Code of Conduct dated January 2026. <br>**Cybersecurity Risk Management and Strategy.** We have a multi-layered cybersecurity risk management program designed to identify risks related to the organization's digital and physical assets, review and assess existing security measures, and implement and manage solutions to mitigate cyber risks. These solutions are designed to protect our facilities, our systems, our partners, our customers, and our financial data in case we experience a cyber incident. Protection measures are designed to detect and guard against threats, including phishing, social engineering, executive targeting, brand impersonation, configuration mistakes, sensitive data leakage, leaked credentials, malicious attacks, third-party risks, vulnerabilities, insider threats (both intentional and unintentional), and password attacks. This type of ongoing vulnerability risk management is crucial as the organization and the external threat landscape evolves. This cybersecurity risk management program is incorporated as part of the Primoris Enterprise Risk Management Program.<br>Our cybersecurity policies and processes are based on the controls within the National Institute of Standards and Technology ("NIST") Framework, and we engage a number of external parties to enhance our cybersecurity oversight. For example, every other year, a third-party consulting firm performs an assessment of our cyber program, measuring our program against the NIST controls with a Capability Maturity Model Integration overlay to determine the program's maturity. The assessment findings are disclosed to the Audit Committee of the Board of Directors and our cross-functional management Security Steering Committee ("SSC"). Any improvements resulting from the assessment are identified, along with action plans. We also use a third-party to perform an annual Breach Assessment targeting our external and internal network environment to determine the strengths and any weaknesses within our cybersecurity processes. As part of the Breach Assessment, our Incident Response Plan is instigated and reviewed to ensure it remains current and effective for all situations. We also have multiple third-party managed Security Operations Centers ("SOC") in place including a SOC for protection of network credentials. <br>Our employees are also an important part of protecting our digital and technical environment. A key area of the cybersecurity program is the education of employees regarding cybersecurity using security awareness training, security bulletins and phishing simulations to reinforce training on a quarterly basis. Security awareness training covers all network users. On an annual basis an Acceptable Use Policy ("AUP") is distributed to employees through our Security Awareness Training System for understanding and acknowledgement. Additionally, all new employees are provided the AUP through the Security Awareness System included with initial security training upon being granted access to our network. | <br>**5.1 years** <br>average tenure of <br>Primoris Board members<br>**88%** <br>of Directors are <br>Independent<br>**100%** <br>of Committees are chaired <br>by independent Directors |

| &nbsp;&nbsp;**What am I being asked to vote on?** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;You are being asked to vote to elect eight Directors to hold office for a one - year term. The experience and qualifications of each Director nominee is included in the biographies in this section. |

---

Each Director of the Company's Board is elected annually to serve a term of one-year. Seven of our current Directors are independent Directors as determined under the guidelines for director independence set forth in our Corporate Governance Guidelines and under all applicable NYSE guidelines.

The Board of Directors' Nominating and Corporate Governance Committee recommended to the Board the nomination of each of the Director nominees for election as Directors for one-year terms expiring at the 2027 Annual Meeting, or until their successors are qualified and elected or their earlier death, resignation or removal. These recommendations were adopted unanimously by the Board. If the nominees become unavailable for any reason, or if any vacancy occurs before the election at the 2027 Annual Meeting (although we know of no reason to anticipate that this will occur), the proxies may be voted for such substitute nominees as the Board may designate.

Each nominee has consented to being named in this Proxy Statement and has agreed to serve if elected. If a quorum is present and entitled to vote on the election of Directors, the nominees receiving a plurality of the votes cast will be elected as Directors. Abstentions and broker non-votes have no effect on the result of the vote; however, abstentions and broker non- votes will be counted as shares present for purposes of determining the presence of a quorum.

### Recommendation of the Board of Directors
&nbsp;&nbsp;Our Board of Directors recommends a vote FOR the election of each of the eight Director nominees as Directors to hold office until our annual meeting of stockholders to be held in 2027 or until their respective successors are duly elected and qualified or upon their earlier death, resignation or removal.<br>

## PROPOSAL 2 – TO APPROVE, IN AN ADVISORY, NON-BINDING VOTE, THE COMPANY'S NAMED EXECUTIVE OFFICER COMPENSATION

### General Information

---

| | |
|:---|:---|
| &nbsp;&nbsp;**What am I being asked to vote on?** | &nbsp;&nbsp;You are being asked to vote on a non-binding, advisory resolution <br>regarding the compensation of the Company's named executive<br>officers. |

---

We believe that our compensation policies and procedures are competitive and strongly aligned with the long-term interest of our stockholders. This advisory stockholder vote, commonly known as "Say-on-Pay", gives you as a stockholder the opportunity to express approval or withhold approval of the compensation we pay our named executive officers through voting for or against the following resolution:

"Resolved, that the stockholders approve the compensation of the Company's named executive officers as disclosed in the Company's 2026 proxy statement pursuant to the disclosure rules of the Securities and Exchange Commission (which disclosure includes the Compensation Discussion and Analysis, the Summary Compensation Table and the other executive compensation tables and related discussions)."

The Company and the Compensation Committee remain committed to the compensation philosophy, policies and objectives outlined under the heading "Compensation Discussion and Analysis" in this proxy statement. The Compensation Committee will continue to review all elements of the executive compensation program and take any steps it deems necessary to continue to fulfill the objectives of the program.

Stockholders are encouraged to carefully review the "EXECUTIVE COMPENSATION" section of this proxy statement for a detailed discussion of the Company's executive compensation program.

Because your vote is advisory, it will not be binding upon the Company or the Board of Directors. However, the Compensation Committee will take into account the outcome of the vote when considering future executive compensation arrangements.

### Recommendation of the Board of Directors
&nbsp;&nbsp;Our Board of Directors recommends a vote FOR the approval of the advisory, non-binding proposal on the compensation of the Company's named executive officers.<br>

## CORPORATE GOVERNANCE PRINCIPLES AND BOARD MATTERS
&nbsp;&nbsp;**Our Board's Mission.** The Board of Directors is elected by the stockholders to oversee the stockholders' interest in the long-term health and overall success of the business and its financial strength. The Board serves as the ultimate decision-making body of the Company, except for those matters reserved to or shared with the stockholders. The Board selects and oversees the members of executive management, who are charged by the Board with conducting the business of the Company.<br>

We believe that effective corporate governance is an important element of our long-term success and ability to create value for our stockholders.

**Corporate Governance Principles and Board Matters**

### Leadership Updates
Effective March 20, 2025, Mr. McCormick separated from the Company and resigned as a director. For continuity while the Board searched for a permanent Chief Executive Officer, the Board appointed Mr. King as Interim President and Chief Executive Officer. Effective November 2025, the Board appointed Koti Vadlamudi as President and Chief Executive Officer, and Mr. King then continued to serve as Chairman of the Board.

### Board Independence
The listing standards of NYSE require that companies have a Board of directors with at least a majority of independent directors. Determining director independence requires that the Board affirmatively determine that the director has no material relationship with us, either directly or as a partner, stockholder or officer of an organization that has a relationship with us.

To assist it in making independence determinations, the Board has adopted independence standards, which include the standards required by the NYSE for independent Directors. In addition, as described in the Company's Corporate Governance Guidelines, a Director will not be deemed to have a material relationship with the Company if the Director:

---

| |
|:---|
| <br>● is an executive officer of another company which is indebted to the Company, or to which the Company is indebted, unless the total amount of either company's indebtedness to the other is more than 1% of the total consolidated assets of the company he or she serves as an executive officer; or <br>|
| <br>● serves as an officer, director or trustee of a tax-exempt organization, unless the Company's discretionary contributions to such organization are more than the greater of $1 million or 2% of that organization's consolidated gross revenues. The Company's automatic matching of employee charitable contributions will not be included in the amount of the Company's contributions for this purpose.<br>|

---

On the basis of the Board independence standards identified above, and such other factors as the Board may consider from time to time, the Board has affirmatively determined that Messrs. Ching, McCallister, Rodriguez, and Schauerman and Mss. Mashinski, Saluja, and Wagner are independent. In addition, the Board had determined that Mr. King was independent prior to his appointment as Interim President and Chief Executive Officer in March 2025 and has been independent since relinquishing that role in November 2025.

**Corporate Governance Principles and Board Matters**

### Board Structure and Committee Composition
The Board has: (i) an Audit Committee, (ii) a Compensation Committee, (iii) a Nominating and Corporate Governance Committee and (iv) a Strategy and Risk Committee. The Board and its Committees meet throughout the year on a set schedule and also hold special meetings, both telephonically and in person, and act by written consent from time to time, as appropriate. During 2025, the Board held a total of seven meetings, the Audit Committee held six meetings, the Compensation Committee held eight meetings, the Nominating and Corporate Governance Committee held four meetings, and the Strategy and Risk Committee held five meetings. The independent Directors meet in executive session at meetings of the Board and Committees as necessary. All of the independent Directors met in executive session at meetings of the Board without any management members four times during 2025.

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Separate** <br>**Chairman** <br>**and CEO** <br>**Roles** | &nbsp;&nbsp;The Board historically has separated the roles of Chairman and CEO, with Mr. King serving as our Non-Executive Chairman of the Board since November 2019, when Mr. McCormick became our CEO, until March 2025 when Mr. King succeeded Mr. McCormick and assumed the role of Interim President and Chief Executive Officer. In April 2025, Mr. McCallister was appointed by the Board as the Lead Independent Director, responsible for chairing the Board meetings in the absence of the Chairman. The Board believes it should have the flexibility to establish a leadership structure that works best for the Company at a particular time, and it reviews that structure from time to time, including in the context of changes in leadership. The Board is of the view that its current leadership structure best serves the objective of effective Board oversight of management and allowed Mr. King to leverage his experience to lead the Board and manage the Company while serving as Interim President and CEO. Following the appointment of Mr. Vadlamudi in November 2025 as CEO, we returned to separate Chairman and CEO roles. |

---

The Board and the Compensation Committee do not make decisions regarding an executive officer's compensation in the presence of such executive officer. The compensation of our Chief Executive Officer and all other executive officers is recommended to the Board of Directors for approval by the Compensation Committee. The Board of Directors acts on the recommendations in a vote in which only independent Directors participate and which takes place during executive sessions of the independent, non-executive Board members.

### Board Role in Risk Oversight
The Board believes that having a system in place for risk management and implementing strategies responsive to our risk profile and exposures is the best way to identify in a timely manner specific material risks, but we can give no assurances that we will be able to identify or mitigate all possible risks in advance. The Company has a clear approach for identifying and mitigating information security risks and four Directors on the Board have information security experience. The Company has also entered into an information security risk insurance policy. While the Board has the ultimate oversight responsibility for the risk management process, its Committees oversee risk in certain specified areas:

![Graphic](prim-20260430xdef14a_a109.jpg)

### Selection of Board Nominees
The Board believes that the Board, as a whole, should include individuals with a broad range of backgrounds and experience to give the Board both depth and breadth in the mix of skills represented for the benefit of our stockholders. The Board endeavors to have a group of Directors with significant industry knowledge and other relevant experience. Accordingly, the Board and the Nominating and Corporate Governance Committee consider the qualifications of Directors and Director nominees professional and educational background, skills, expertise, potential time commitment, and other criteria.

The Board and Nominating and Corporate Governance Committee also understand the importance of Board refreshment and aim to achieve a balance between the knowledge that comes from longer-term service on the Board with the new experience, ideas and energy that can come from adding Directors to the Board. The Board and Nominating and Corporate Governance Committee view the consistent focus on Board membership criteria, Board composition and size, as well as the anticipation of vacancies, to be integral parts of Board refreshment.

Our Corporate Governance Guidelines contain Board membership criteria that apply to current Directors as well as Board nominees. The Nominating and Corporate Governance Committee regularly evaluates the appropriate size of the Board and whether any vacancies on the Board are expected due to retirement or otherwise. If any vacancies are anticipated or arise, the

**Corporate Governance Principles and Board Matters**

Nominating and Corporate Governance Committee will consider Director candidates suggested by current Board members, management, third-party search firms and others. The Nominating and Corporate Governance Committee will also consider Director nominations by stockholders that are made in compliance with our bylaws. All applications, recommendations or proposed nominations for Board membership received by the Company will be referred to the Nominating and Corporate Governance Committee. The manner in which the qualifications of a nominee are evaluated does not differ if the nominee is recommended by a stockholder.

The Nominating and Corporate Governance Committee's consideration of a candidate as a Director includes assessment of the individual's understanding of our business, the individual's professional and educational background, skills, expertise, potential time commitment, and other criteria established by the Nominating and Corporate Governance Committee from time to time. To provide such a contribution to us, a Director must generally possess one or more of the following, in addition to personal and professional integrity:

---

| |
|:---|
| <br>● Experience in corporate management; <br>|
| <br>● Experience in our industry; <br>|
| <br>● Experience as a Board member or officer of a publicly held company; <br>|
| <br>● Experience in financial and accounting matters; <br>|
| <br>● Broad range of expertise and experience in substantive matters related to our business; and <br>|
| <br>● Practical and mature business judgment.<br>|

---

The Nominating and Corporate Governance Committee has adopted procedures for evaluating the suitability of potential Director nominees, including qualifications for a "financial expert" and financially literate members for the Audit Committee.

The Nominating and Corporate Governance Committee will consider all stockholder recommendations for candidates for the Board, which should be sent to the Nominating and Corporate Governance Committee, c/o Secretary, Primoris Services Corporation, 2300 N. Field Street, Suite 1900, Dallas, Texas 75201.

The Nominating and Corporate Governance Committee will evaluate recommendations for Director nominees submitted by Directors, management or qualifying stockholders in the same manner, by using the criteria stated above. All Directors and Director nominees will be required to submit a completed Directors' and Officers' questionnaire as part of the nominating process. At the discretion of the Nominating and Corporate Governance Committee, the process may also include interviews and additional background and reference checks for non-incumbent nominees.

### Annual Board and Committee Evaluations
Primoris believes that regular Board evaluations are an instrumental component of building and maintaining a strong and effective Board. Each year, the Nominating and Corporate Governance Committee, together with the Company's Corporate Secretary, coordinates the Board performance evaluations that assist the Board in determining whether the Board, its Committees, and each member of the Board are functioning effectively. This process also assists the Board in determining how it can improve its processes and effectiveness. These evaluations are conducted through a combination of formal and informal processes, including questionnaires which solicit open-ended and candid feedback on an anonymous basis. The collective ratings and comments are compiled, summarized and presented to the Board and its Committees and provide the Board valuable information on a range of topics, including new Director searches, Committee composition, and subject matter for continuing Board education.

### Code of Conduct
The Company has a Code of Conduct that complies with the rules and regulations adopted by the SEC and NYSE listing standards and are applicable to all of our Directors, officers and employees. The Code of Conduct also includes a supplement with additional policies that are applicable to the CEO, CFO and all senior financial officers of the Company. The Code of Conduct is available on the Investor Relations/Governance section of our website at *www.prim.com*. We intend to post amendments to, or waivers under, if any, our Code of Conduct (to the extent applicable to our Directors or Chief Executive Officer, Principal Financial Officer, or Principal Accounting Officer) at this location on our website. Among other matters, this Code of Conduct is designed to promote:

## AUDIT COMMITTEE REPORT
*The following report of the Audit Committee does not constitute soliciting material and shall not be deemed filed or incorporated by reference into any other filing by us under the Securities Act or the Exchange Act, except to the extent we specifically incorporate this report by reference.*

The primary purpose of the Audit Committee is to assist the Board in fulfilling its responsibility to oversee (i) the integrity of our financial statements, (ii) the independent registered public accounting firm's qualifications, independence and performance, (iii) our accounting and financial reporting processes, (iv) our compliance with financial, legal and regulatory requirements, and (v) the audits of our financial statements. The Audit Committee is directly responsible for the appointment, compensation and oversight of the work of the independent registered public accounting firm. The independent registered public accounting firm reports directly to the Audit Committee.

Management has the primary responsibility for the preparation of the financial statements and the reporting process, as well as performing an evaluation and assessment of the effectiveness of the Company's internal control over financial reporting using the control criteria framework of the Committee of Sponsoring Organizations of the Treadway Commission (COSO 2013). Our management has represented to the Audit Committee that the consolidated financial statements for the fiscal year ended December 31, 2025, were prepared in accordance with generally accepted accounting principles and that the Company's internal control over financial reporting was effective as of December 31, 2025. In addition to its review and discussion with management of the audited consolidated financial statements and in the performance of its oversight function over internal controls, the Audit Committee reviewed and discussed with management the critical accounting policies that were applied in the preparation of our consolidated financial statements, and the process for certifications by our Chief Executive Officer and our Chief Financial Officer.

Our independent registered public accounting firm is responsible for auditing the consolidated financial statements for the fiscal year ended December 31, 2025, and issuing an opinion on the effectiveness of the Company's internal control over financial reporting as of December 31, 2025. The Audit Committee discussed the results of the work of the independent registered public accounting firm. The Audit Committee discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Securities and Exchange Commission and the Public Company Accounting Oversight Board ("PCAOB"), including PCAOB AS 1301 (Communications with Audit Committees). In addition, the Audit Committee received from the independent registered public accounting firm the written disclosures required by applicable requirements of the PCAOB regarding the independent accountant's communications with the Audit Committee concerning independence and discussed with them their independence from the Company and its management. The Audit Committee also evaluated whether the independent registered public accounting firm's provision of non-audit services to us was compatible with the auditor's independence and determined it was compatible. The members of the Audit Committee met in executive session (with no management in attendance) with the independent registered public accounting firm each quarter during the year.

The Board determined that the Audit Committee members meet the independence requirements of Rule 10A-3 of the Exchange Act and applicable NYSE independence rules.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board, and the Board approved, the inclusion of the audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2025, for filing with the SEC.

#### Overview
Our management compensation programs apply broadly to all officers and management persons at the Company with modifications to reflect the different management levels, experience levels, and types and breadth of responsibilities. The Company's goal is to align compensation so that the entire management team is committed to the Company's corporate objectives of achieving both near- and long-term profitable growth.

In 2023, the Compensation Committee implemented an all-cash Annual Incentive Plan ("AIP") along with an equity based Long-Term Incentive Plan ("LTIP"). The AIP provides for an annual incentive calculation that is based on Company performance metrics and is paid in cash. The LTIP provides for an annual grant of equity awards. The first grant under the LTIP occurred in March 2023. We believe this incentive structure will further enhance value for our stockholders.

#### Compensation Philosophy

---

| | |
|:---|:---|
| &nbsp;&nbsp;Our goal is to create an executive compensation program that will appropriately reward our executives for their roles in creating both near-term and long-term value for our stockholders without encouraging or rewarding excessive risk. | &nbsp;&nbsp;The Compensation Committee is charged with reviewing our executive officers' cash and equity compensation to determine whether these provide adequate incentives and motivation to our executive officers and whether they adequately compensate the executive officers relative to comparable officers in other companies within our industry in light of our performance. Our goal is to be competitive with other similarly situated companies in our industry and to attract, retain and motivate key executives. |

#### Processes and Procedures for Determining Executive Compensation
The following describes the roles of the key participants and sources of information in the process of setting compensation.

&nbsp;&nbsp;**Role of the Compensation Committee**<br>The Compensation Committee reviews and approves compensation and benefit policies and objectives, and determines whether our officers, Directors and employees are generally compensated in accordance with these objectives and carries out certain of the Board's responsibilities relating to the compensation of our executives. The Compensation Committee operates under a charter approved by the Board. All of the Compensation Committee members meet NYSE independence standards and are "Non-employee Directors" as defined by the Exchange Act.<br>For our executives' compensation, the Compensation Committee approves the structure of the compensation program. In addition, the Compensation Committee, in coordination with the recommendations by the CEO (excluding his own), directly sets the compensation for the Company's senior officers, including all NEOs. The Compensation Committee is involved in all matters where approval is appropriate for tax or regulatory reasons.<br>

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Role of Board of Directors**<br>The Board provides final approval of Compensation Committee compensation changes for the executive officers. This approval is obtained at an independent Director session without the presence of management Directors. | &nbsp;&nbsp;**Role of External Advisor**<br>The Compensation Committee engages Meridian as an independent consulting resource as needed to help it with its responsibilities. When requested, information and advice provided by Meridian may include reviews and critique of our executive compensation philosophy and strategies; a competitive analyses of competition program design; and presentations to update market trends. Meridian attends Compensation Committee meetings as requested by the Compensation Committee and conducts private meetings with the Compensation Committee without management representatives at the Committee's request. |

| &nbsp;&nbsp;**Role of Executives**<br>Our CEO is responsible for reviewing the compensation and performance of all the executive officers, other than himself. He makes recommendations to the Compensation Committee for adjustments in compensation and for any other compensation changes. The Compensation Committee uses the CEO's recommendations and its evaluation of current individual and business performance and historical individual and business performance to review and approve adjustments in compensation. Our CEO is not present during and does not participate in the discussion of any elements of his compensation with the Compensation Committee.<br>Our CFO, Chief Human Resources Officer, and other Senior Leaders facilitate the sharing of information among the Company, the compensation consultant and the Compensation Committee. In this role, the Leaders communicate with the compensation consultant at the direction of the Compensation Committee. | &nbsp;&nbsp;**Role of External Advisor**<br>The Compensation Committee engages Meridian as an independent consulting resource as needed to help it with its responsibilities.

In July 2025, the Compensation Committee approved a compensation peer group comprised of 15 publicly traded companies (Aecom, Inc., Ameresco, Inc., APi Group Corporation, Arcosa, Inc., Centuri Holdings, Inc., Comfort Systems USA, Inc., Dycom Industries, Inc., EMCOR Group, Inc., Everus Construction Group, Inc., Fluor Corporation, Granite Construction, Inc., IES Holding, Inc., MasTec, Inc., MYR Group, Inc., and Valmont Industries, Inc.). In determining 2025 pay levels for the NEOs, the Compensation Committee reviewed pay data at the 25th, 50th and 75th percentiles for the compensation peer group as well as broader survey data from Aon-Radford, Willis Towers Watson and Mercer. However, the Compensation Committee takes a holistic approach that, in addition to external benchmarking, also considers input from their independent advisor (Meridian), recommendations from our CEO (excluding his own compensation), each executive's individual performance, the overall Company performance and our compensation strategy. For our NEOs, including the CEO, the Compensation Committee recommends any pay changes to the full Board of Directors for formal approval. |

#### Annual Incentive Plan
The Company's Annual Incentive Plan ("AIP") for senior leadership and executives is designed to provide annual awards payable in cash.

An eligible NEO that begins employment during the performance year will generally be prorated for their first year based on their date of hire, unless otherwise determined by the CEO and with the approval of the Compensation Committee. Generally, a NEO must be employed by the Company on the date any cash incentive compensation is paid. Otherwise, the NEO forfeits any and all rights to such compensation unless contractual provisions entitle the NEO to a full or pro-rated amount or otherwise as determined by the CEO (other than with respect to himself) and with approval of the Compensation Committee.

#### Measurable Performance Awards
The measurable performance award for each NEO under the AIP is calculated as a percentage of such NEO's base salary earned during the year (the "AIP Target"), which is then multiplied by the weighted achievement percentage associated with the Company performance metrics, as set forth in the following calculation:

**Executive Compensation**

The Compensation Committee established the following AIP Targets for each NEO for the 2025 performance year:

---

| | | | |
|:---|:---|:---|:---|
| <br>**Name**  | <br>**Base Salary Earned**  | **AIP Target**<br>**(% of Base Salary)**  | <br>**AIP Target Amount** |

| &nbsp;&nbsp;Kenneth M. Dodgen  | 596667 | 100 | 596667 |
| &nbsp;&nbsp;John M. Perisich  | 608489 | 100 | 608489 |
| &nbsp;&nbsp;Jeremy Kinch | 589000 | 100 | 589000 |

| &nbsp;&nbsp;Thomas E. McCormick<sup>(2)</sup>  | 973000 | 120 | 246329 |

---

1 Mr. Vadlamudi and Mr. King were not eligible for AIP in 2025.

2 Mr. McCormick's 2025 AIP target bonus was prorated based on the terms of his separation agreement.

### Adjusted EBITDA Component
The Adjusted EBITDA Component of the AIP is based on annual Adjusted EBITDA, which is equal to net income (loss) before interest, income taxes, depreciation and amortization, as further adjusted for certain items, including (i) non-cash stock-based compensation expense; (ii) transaction/integration and related costs; (iii) asset impairment charges; (iv) severance and restructuring changes; (v) change in fair value of contingent consideration liabilities; and (vi) selected (gains) charges that are unusual or non-recurring. A payout occurs only if actual Adjusted EBITDA is greater than the threshold amount and payout under this component is subject to a maximum achievement percentage. Based on the performance scale adopted by the Compensation Committee for the 2025 performance year, NEOs could earn awards for this component of the AIP as follows (when performance falls between the designated payout points above the threshold amount, the awards are determined by interpolation):

---

| | | |
|:---|:---|:---|
| **If Adjusted EBITDA is (in millions)**  | **% of Target**  | **Achievement %**  |
| &nbsp;&nbsp;Below $382.2 (threshold)  | Less than 85% | 0% |
| &nbsp;&nbsp;$382.2 | 85% | 25% |
| &nbsp;&nbsp;$449.7 (target)  | 100% | 100% |
| &nbsp;&nbsp;At or above $494.7 (maximum)  | 110% | 200% |

---

For the 2025 performance year, the Compensation Committee established a target AIP Adjusted EBITDA of $449.7 million. The Compensation Committee concluded that actual AIP Adjusted EBITDA for the performance year was $531.1, which represents approximately 118.1% of the target and an achievement percentage of 200.0%.

The following table details the achievement associated with the AIP Net Income component:

---

### New Business Generated Component
The New Business Generated Component of the AIP measures the amount of new business the Company has generated in the plan year. A payout occurs only if actual new business generated is greater than the threshold amount and payout under this component is subject to a maximum achievement percentage. Based on the performance scale adopted by the Compensation Committee for the 2025 performance year, NEOs could earn awards for this component of the AIP as follows (when performance falls between the designated payout points above the threshold amount, the awards are determined by interpolation):

---

| | | |
|:---|:---|:---|
| **If New Business Taken is (in millions)**<sup>(1)</sup>  | **% of Target**  | **Achievement %**  |
| &nbsp;&nbsp;Below $5,559.5 (threshold)  | Less than 85% | 0% |
| &nbsp;&nbsp;$5559.5 | 85% | 25% |
| &nbsp;&nbsp;$6,540.6 (target)  | 100% | 100% |
| &nbsp;&nbsp;At or above $7,194.6 (maximum)  | Greater than 110% | 200% |

---

<sup>1</sup> Sum of new contracts executed where scope is adequately defined, and revenue generated under contracts where scope is not adequately defined during the plan year.

For the 2025 performance year, the Compensation Committee established a target AIP New Business Generated of $6,540.6 million. The Compensation Committee concluded that actual AIP New Business Generated for the performance year was $7,251.2 million, which represents approximately 110.9% of the target and an achievement percentage of 200.0%.

### Cash Management Component
The Cash Management Component of the AIP signifies the ability of the Company to manage cash during the 2025 plan year. A payout occurs only if actual cash management is better than the threshold amount and payout under this component is subject to a maximum achievement percentage. Based on the performance scale adopted by the Compensation Committee for the 2025 performance year, NEOs could earn awards for this component of the AIP as follows (when performance falls between the designated payout points above the threshold amount, the awards are determined by interpolation):

---

| | | |
|:---|:---|:---|
| **If Cash Management is (in days)**<sup>(1)</sup>  | **% of Target**  | **Achievement %**  |
| &nbsp;&nbsp;Above 70.0 (threshold)  | Greater than 116.7% | 0% |
| &nbsp;&nbsp;&nbsp;&nbsp;70.0 | 116.7% | 25% |
| &nbsp;&nbsp;&nbsp;&nbsp;60.0 (target) | 100% | 100% |
| &nbsp;&nbsp;At or below 50.0 (maximum)  | Less than 83.3% | 200% |

---

<sup>1</sup> Cash management is measured as the average days of accounts receivable outstanding plus the average days of unbilled contract revenue outstanding less the average days of deferred contract revenue outstanding.

For the 2025 performance year, the Compensation Committee established a target AIP Cash Management of 60 days. The Compensation Committee concluded that actual AIP Cash Management for the performance year was 42 days, which represents approximately 70.0% of the target and an achievement percentage of 200.0%.

The following table details the achievement associated with the AIP Cash Management component:

### Safety Performance Component
The final component of the AIP is based on the Company's achievement of measurable safety performance goals. Performance with respect to this component is measured by the Company's consolidated total recordable incident rate ("TRIR") for the performance year. A payout occurs only if actual TRIR is below the threshold amount and payout under this component is subject to a maximum achievement percentage. Based on the performance scale adopted by the Compensation Committee for the 2025 performance year, NEOs could earn awards for this component of the AIP as follows (when performance falls between the designated payout points below the threshold amount, the awards are determined by interpolation):

---

| | | |
|:---|:---|:---|
| **If TRIR is**<sup>(1)</sup>  | **% of Target**  | **Achievement %**  |
| &nbsp;&nbsp;Above 0.60 (threshold)  | Greater than 120% | 0% |
| &nbsp;&nbsp;&nbsp;&nbsp;0.60 | 120% | 25% |
| &nbsp;&nbsp;&nbsp;&nbsp;0.50 (target)  | 100% | 100% |
| &nbsp;&nbsp;Below 0.45 (maximum)  | Less than 90% | 200% |

---

<sup>1</sup> TRIR is defined as the number of work injuries in the performance year multiplied by 200,000 divided by reportable hours worked.

For the 2025 performance year, the Compensation Committee established a target AIP TRIR of 0.50. The Compensation Committee concluded that actual AIP TRIR for the performance year was 0.50, which represents 100.0% of the target and an achievement percentage of 100.0%.

The following table details the achievement associated with the AIP Safety component:

#### Long-Term Incentive Plan ("LTIP")
The LTIP for senior leadership is designed to provide our NEOs with long-term incentive awards payable in equity. Targets are reviewed and set by the Compensation Committee. In connection with the new LTIP design, the 2023 award values approved by the Compensation Committee included both annual and transition components. This approach was intended to be a one-time occurrence and, in 2024 and 2025, LTIP award values were based on the annual component only. As performance periods are completed, we discuss the achievement and any payouts, along with retroactively disclosing the targets for the metrics that do not cause competitive harm, after the relevant portion of the LTIP awards vest.

In 2023, 75% of the equity granted was in the form of PSUs and 25% was in the form of RSUs. RSUs vest over three years in increments of 25% after year one, 25% after year two and 50% after year three. PSUs for the 2023 plan year are eligible to vest over three years in increments of 25% after year one, 25% after year two and 50% after year three. Actual vested shares under PSU awards for any vesting year are determined by performance for that year against metrics as outlined below. The Compensation Committee approved, for the 2023 plan year only, the PSU vesting schedule to be ratable with the aim to effectively transition participation from our previous incentive compensation plan. For 2024 and beyond, 65% of the equity granted was in the form of PSUs and 35% was in the form of RSUs. RSUs vest over three years in increments of 25% after year one, 25% after year two and 50% after year three and 100% of the PSUs will cliff vest after year three.

The table below represents the number of PSUs and RSUs granted under the LTIP program in 2025:

**Executive Compensation**

The following is the calculation of the shares vesting based on the 2025 performance period:

### Cumulative Net Income Component
The Net Income Component of the LTIP is based on cumulative net income. Vesting occurs only if actual cumulative net income is greater than the threshold amount and payout under this component is subject to a maximum achievement percentage. For Messrs. Dodgen and Perisich, 100% of the performance scale adopted by the Compensation Committee was based on total Company performance at the time of grant. For Mr. Kinch, 50% of the performance scale was based on total Company performance and 50% of the performance scale was based on the specific business he was responsible for at the time of grant. Based on the performance scale adopted by the Compensation Committee for the 2025 performance year, NEOs could earn PSU awards for this component of the LTIP as follows (when performance falls between the designated payout points above the threshold amount, the awards are determined by interpolation).

Awards based on total Company results are as follows:

---

| | | |
|:---|:---|:---|
| **If Net Income is (in millions)** | **% of Target**  | **Achievement %**  |
| &nbsp;&nbsp;Below $278.6 (threshold) | Less than 75% | 0% |
| &nbsp;&nbsp;$278.6  | 75% | 25% |
| &nbsp;&nbsp;$371.5 (target) | 100% | 100% |
| &nbsp;&nbsp;At or above $445.8 (maximum) | 120% | 200% |

---

Awards based on Mr. Kinch's specific business results are as follows:

---

| | | |
|:---|:---|:---|
| **If Net Income is (in millions)** | **% of Target**  | **Achievement %**  |
| &nbsp;&nbsp;Below $114.2 (threshold) | Less than 75% | 0% |
| &nbsp;&nbsp;$114.2  | 75% | 25% |
| &nbsp;&nbsp;$152.3 (target) | 100% | 100% |
| &nbsp;&nbsp;At or above $182.8 (maximum) | 120% | 200% |

---

For the 2025 performance year, the Compensation Committee established a target LTIP Total Company Cumulative Net Income of $371.5 million. The Compensation Committee concluded that actual Total Company Cumulative Net Income for the performance year was $581.3 million, which represents approximately 156.5% of the target and an achievement percentage of 200.0%.

For the 2025 performance year, the Compensation Committee established a target LTIP Cumulative Net Income for Mr. Kinch's specific business of $152.3 million. The Compensation Committee concluded that actual Cumulative Net Income for Mr. Kinch's specific business for the performance year was $322.2 million, which represents approximately 211.6% of the target and an achievement percentage of 200.0%.

The following table details the actual payouts associated with the LTIP Cumulative Net Income component which were paid to our NEOs in shares of Primoris common stock after completion of the performance period ended December 31, 2025:

**Executive Compensation**

### Operating Margin Percentage Component
The Operating Margin Percentage of the LTIP is based on the annual operating margin percentage. A vesting occurs only if actual operating margin percentage is greater than the threshold amount and payout under this component is subject to a maximum achievement percentage. For Messrs. Dodgen and Perisich, 100% of the performance scale adopted by the Compensation Committee was based on total Company performance at the time of grant. For Mr. Kinch, 50% of the performance scale was based on total Company performance and 50% of the performance scale was based on the specific business he was responsible for at the time of grant. Based on the performance scale adopted by the Compensation Committee for the 2025 performance year, NEOs could earn PSU awards for this component of the LTIP as follows (when performance falls between the designated payout points above the threshold amount, the awards are determined by interpolation):

Awards based on total Company and Mr. Kinch's specific business results are as follows:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**If Operating Margin is** | **% of Target**  | **Achievement %**  |
| &nbsp;&nbsp;Below 3.60% (threshold) | Less than 75% | 0% |
| &nbsp;&nbsp;3.60% | 75% | 25% |
| &nbsp;&nbsp;4.80% (target) | 100% | 100% |
| &nbsp;&nbsp;At or above 5.76% (maximum) | 120% | 200% |

---

For the 2025 performance year, the Compensation Committee established a target LTIP Total Company Operating Margin Percentage of 4.8%. The Compensation Committee concluded that actual Total Company Operating Margin Percentage for the performance year was 5.5%, which represents approximately 114.4% of the target and an achievement percentage of 171.9%.

For the 2025 performance year, the Compensation Committee established a target LTIP Operating Margin Percentage for Mr. Kinch's specific business of 4.8%. The Compensation Committee concluded that actual Operating Margin Percentage for Mr. Kinch's specific business for the performance year was 7.4%, which represents approximately 154.4% of the target and an achievement percentage of 200.0%.

**Executive Compensation**

### Other Compensation Items

#### Stock Ownership Guidelines
In October 2024, our Nominating and Corporate Governance Committee established minimum stock ownership guidelines for executive officers, with the goal of promoting equity ownership and aligning our executive officers' interests with our stockholders. The ownership guidelines are currently established at the following minimum levels:

---

| | |
|:---|:---|
| **Name**  | **Guideline** |
| &nbsp;&nbsp;Chief Executive Officer | 5x base salary |
| &nbsp;&nbsp;Other Executive Officers | 3x base salary |

---

Officers will have five years from adoption of these stock ownership guidelines or five years from the date of hiring or promotion to acquire the shares needed to meet the stock ownership guidelines. The Company's Secretary will evaluate compliance on an annual basis, as of April 29 of each year, and not on a running basis. If an officer achieves compliance with these stock ownership guidelines as of April 29 of any year, the officer will not be deemed to have failed to comply with these guidelines as of April 29 of any future year as a result of a decline in the Company's stock price if the officer has not sold any shares. The Secretary will provide a compliance report to the Nominating and Corporate Governance Committee prior to the annual election of executive officers.

The following are used in determining stock ownership for purposes of these guidelines:

---

| |
|:---|
| <br>● shares owned separately by the officer or owned either jointly with, or separately by, his or her immediate family members residing in the same household; <br>|
| <br>● shares held in trust for the benefit of the officer or his immediate family members; <br>|
| <br>● shares purchased on the open market; <br>|
| <br>● shares purchased through the Company's Employee Stock Purchase Plan; <br>|
| <br>● vested and unvested time-based restricted stock or restricted stock units; and <br>|
| <br>● dividend equivalent shares.<br>|

---

#### Anti-Hedging and Pledging Policy
The Company prohibits Directors and executive officers from entering into speculative transactions in Primoris securities, such as prepaid variable forwards, forward sale contracts, short sales, equity swaps, collars, zero-cost collars, exchange funds, publicly traded options, puts, calls and other derivative transactions. We believe these prohibitions ensure that levels of stock ownership in accordance with our stock ownership guidelines are effective in aligning each individual's interests with those of our stockholders.

The Company also prohibits all Covered Persons from purchasing Company securities on margin, borrowing against Company securities held in a margin account, or pledging Company securities as collateral for a loan.

#### Pay Recoupment (Clawback) Policy
The Board has adopted a Dodd-Frank Compensation Recovery Policy for NEOs, effective as of October 2, 2023.

If the Company is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the federal securities laws, the Company will recover any erroneously awarded incentive-based compensation from current or former officers subject to reporting under Section 16 of the Exchange Act that was received within the applicable recovery period. The Compensation Committee of the Board has discretion to make all decisions under this policy.

#### Risk Assessment
The Compensation Committee considered the risks associated with the Company's compensation policies and practices for executive officers and determined that it did not identify any risks that are reasonably likely to have a material adverse effect on the Company. This conclusion was based on the following considerations:

<br>● The Compensation Committee structures compensation at the senior management level to consist of both fixed and variable compensation. The base salaries of senior management are typically set at market levels and are designed to provide a steady income so that senior management does not feel pressured to focus exclusively on stock price performance to the detriment of other important business metrics. The variable portions of compensation are generally designed to reward both short-term and long-term performance <br>

62 &nbsp;&nbsp;&nbsp;&nbsp; PRIMORIS 2026 PROXY STATEMENT

[**Table of Contents**](#TOC)

**Executive Compensation**

---

| |
|:---|
| <br>as measured under several financial and operational performance metrics. Additionally, PSUs and RSUs generally vest over three years, which the Compensation Committee believes encourages senior management to focus on sustained stock appreciation and promotes retention. The Compensation Committee believes that the variable elements of compensation are a sufficient percentage of overall compensation to motivate short-term and long-term results, while the fixed element is also sufficient such that senior management is not encouraged to take unnecessary or excessive risks in doing so. <br>|
| <br>● The Compensation Committee believes the financial and operational performance measures for determining cash and equity awards earned under our incentive plans are aligned with the Company's short-term and long-term operating and strategic plans and that the targets for those measures are set at appropriate levels that do not encourage unnecessary or excessive risk taking. <br>|
| <br>● The Board has adopted stock ownership guidelines for our executive officers, which the Compensation Committee believes provide a considerable incentive for management to consider the Company's long-term interests because a meaningful portion of their personal investment portfolio consists of the Company's Common Stock. <br>|
| <br>● Individual awards are capped under our AIP, which the Compensation Committee believes mitigates excessive risk taking. <br>|
| <br>● The Company has a Clawback Policy that requires us to recover certain incentive compensation from executive officers for the achievement of certain Company financial results that were subsequently subject to a restatement.<br>|

---

#### Tax Matters
Internal Revenue Code Section 162(m) limits to $1 million the annual tax deduction for compensation paid by public companies to each "covered employee", a group which generally includes all named executive officers. The Company structured the 2013 Equity Incentive Plan with the intention that certain performance awards would qualify for tax deductibility. However, because of amendments to Section 162(m) for the Tax Cuts and Jobs Act of 2017 ("Tax Act"), the performance awards in the 2013 and 2023 Equity Incentive Plans are now subject to the deduction limitation along with other compensation. Further, the Tax Act requires that employees who become covered employees will remain covered employees until separation from the Company.

#### Equity Grant Practices
The Company grants annual equity awards at approximately the same time each year following the approval by the Compensation Committee. The Compensation Committee and the Board do not have a policy or practice to take into account material non-public information when determining the timing or terms of equity awards nor to time disclosure of material non-public information for the purpose of affecting the value of executive compensation with such equity awards. In 2025, the Company did not grant stock options, stock appreciation rights, or similar option-like awards.

### Employment Agreements for Named Executive Officers
Effective November 10, 2025, the Company entered into an employment agreement with Koti Vadlamudi, setting out his annual base salary, plus a performance bonus opportunity. In the event of termination without cause, resignation with good reason or by reason of death or disability, severance benefits will be paid, including a lump sum equal to 200% of the annual base salary, a pro-rated bonus for the current year, up to one year of the employee's share of the premium for COBRA medical benefits, and accelerated vesting of any unvested RSUs and PSUs. In the event of termination due to a change in control, severance benefits will be paid, including a lump sum equal to 2.5 times the sum of the annual base salary in effect upon the termination date and the target bonus for the year in which the termination date occurs, a bonus, if any, which would have been payable to the employee for the calendar year in which the termination date occurs, up to 30 months of the employee's share of the premium for COBRA medical benefits and accelerated vesting of any unvested RSUs and PSUs.

Effective April 1, 2022, the Company entered into employment agreements with Kenneth M. Dodgen and John M. Perisich setting out their annual base salary, plus a performance bonus opportunity. Effective January 6, 2025, the Company entered into an employment agreement with Jeremy Kinch setting out his annual base salary, plus a performance bonus opportunity. In the event of termination without cause, resignation with good reason or by reason of death or disability, severance benefits will be paid, including a lump sum equal to 100% of the annual base salary, a pro-rated bonus for the current year, up to one year of the employee's share of the premium for COBRA medical benefits, and accelerated vesting of any unvested RSUs and PSUs. In the event of termination due to a change in control, severance benefits will be paid, including a lump sum equal to 2.0 times the sum of the annual base salary in effect upon the termination date and the target bonus for the year in which the termination date occurs, a pro-rated bonus, if any, which would have been payable to the employee for the calendar year in which the termination date occurs, up to 24 months of the employee's share of the premium for COBRA medical benefits and accelerated vesting of any unvested RSUs and PSUs.

All of the employment agreements contain certain restrictive covenants that prohibit the executives from disclosing information that is confidential to us and our subsidiaries and generally prohibits them, during the employment term and for two years thereafter, in the event of a termination for cause or resignation without good reason from soliciting or hiring our employees or our subsidiary employees and from using our confidential information to divert any customer business from us, or to otherwise alter the manner in which a customer does business with us.

The grant date fair value was based on the market closing price of our stock one day prior to the grant date. This amount reflects our accounting expense to be recognized over the vesting period of the RSUs awarded and does not correspond to the actual value that will be recognized by the NEO. The awards for Messrs. Dodgen and Perisich, were granted on March 1, 2025, 2024, and 2023. The awards for Mr. King and Mr. Vadlamudi were granted on April 1, 2025, and November 10, 2025, respectively. A portion of Mr. Kinch's awards was granted on March 1, 2025, and a portion was granted on April 1, 2025, in connection with his promotion to Chief Operating Officer. |

<sup>4</sup> The amounts shown reflect the aggregate grant date fair value of PSUs granted during the fiscal year ended December 31, 2025, and 2024, calculated in accordance with FASB ASC Topic 718. The grant date fair value is based on the closing price of our common stock one day prior to the grant date. Grant date fair value of PSUs was based on probable achievement of the applicable performance goals, and the value ultimately realized by the NEO upon actual vesting of the awards may or may not be equal to this determined value. PSUs vest upon completion of a performance period (subject to continued service), with the amount that vests based on the achievement of certain Company performance conditions. The final amount of earned PSUs can range from 0% to a maximum of 200% (assuming the highest level of performance) of the target amount of unearned PSUs that were granted, and upon settlement, shares of our common stock are issued for each earned PSU. With respect to the PSUs awarded during fiscal year 2025, the grant date fair value, assuming the highest level of Company performance conditions were to be achieved, would be as follows: for Mr. Dodgen, $1,197,628; for Mr. Perisich, $1,524,044; and for Mr. Kinch, $1,299,822.

<sup>1</sup> The threshold, target and maximum amounts in these columns show the range of cash payouts targeted for 2025 that could have been earned based on the achievement of performance goals under the AIP, which is discussed in further detail in "Compensation Discussion and Analysis—Compensation Committee Pay Decisions—Annual Bonuses". The actual amounts paid are described in the "Non-Equity Incentive Plan Compensation" column of the "Summary Compensation Table."

<sup>2</sup> The amounts shown represent the number of shares of our common stock that could be earned with respect to PSUs granted under the 2025 long-term incentive plan. The number of PSUs that will become earned and vest, and the resulting number of shares of common stock to be issued, will be determined as soon as administratively practical after completion of the three-year performance period ending December 31, 2027, and the number of shares can range from 0% to a maximum of 200% of the target number. PSUs are described in further detail under Compensation Discussion & Analysis—Long-Term Incentive Plan.

<sup>3</sup> The amounts shown represent the number of RSUs and PSUs that were granted under the 2025 long-term incentive plan. The RSUs awarded vest 25% after year one, 25% after year two and 50% after year three, assuming the NEO continues to meet the requirements for vesting, and the initial vesting occurs one year from the grant date.

<sup>4</sup> The amount shown in this column represents the aggregate grant date fair value of the RSUs and PSUs granted by our Board of Directors computed in accordance with FASB ASC Topic 718.

<sup>1</sup> Market value is calculated by multiplying the number of RSUs and PSUs, as applicable, that have not vested by the closing market price of our Common Stock on December 31, 2025 (the last business day of our most recently completed fiscal year), which was $124.14 per share.

<sup>2</sup> The amounts shown represent the maximum number of shares of common stock that could be earned with respect to PSUs granted under the long-term incentive plan, which has a performance period ending December 31, 2026 and 2027. Pursuant to SEC disclosure instructions, because the Company's performance in previous years on the metrics governing our PSUs granted under the long-term incentive plan exceeded target performance, the number of such unearned PSUs and payout value of such unearned PSUs is calculated assuming maximum performance criteria is achieved. The target number of PSUs granted under the long-term incentive plan that were outstanding as of December 31, 2025, were as follows: Mr. Dodgen—22,782; Mr. Perisich—28,990; and Mr. Kinch—18,685. The actual number of PSUs that will ultimately become earned will be determined as soon as administratively practicable after completion of the performance periods and can range from 0% to a maximum of 200% of the target number.

<sup>3</sup> Includes unvested awards of RSUs covering (i) 1,794 shares that vest on November 10, 2026; (ii) 1,794 shares that vest on November 10, 2027, and (iii) 3,587 shares that vest on November 10, 2028.

### Potential Payments Upon Termination
The Company has entered into employment agreements with Messrs. Vadlamudi, Dodgen, Perisich and Kinch. The terms of the employment agreements provide that we must pay certain severance benefits in the event the NEO is terminated by us for any reason other than for "cause".

The following table shows amounts that would be payable to each of the following NEOs under the scenario that the executive is terminated without cause or leaves due to death or disability. The table assumes that the terminating event occurred on December 31, 2025, and the NEO returned an executed release of claims (other than if leaving due to death), on which these termination payments are conditioned.

The actual number of unearned PSUs that would become earned upon occurrence of the event would be based on the achievement of target performance goals, pro-rated for the number of months of the applicable performance period that have elapsed as of the termination date divided by the total number of months in the applicable performance period. The value is based on the closing price of our Common Stock at December 31, 2025 (the last business day of our most recently completed fiscal year).

<sup>3</sup> In the event of termination without cause, or by death or disability, calculated as a lump sum payment equal to the bonus amount that would have been paid for the calendar year.

<sup>4</sup> In the event of the executive's termination without cause or disability, he is entitled to up to one year of healthcare benefits. The amount reflects both the employee and employer portion of health care premium costs.

<sup>5</sup> Each executive is allowed an accrual of up to five weeks of vacation. For purposes of this table, it was assumed that the full five weeks would be paid upon termination.

<sup>2</sup> Represents accelerated vesting, as of December 31, 2025, of RSUs and PSUs granted to each of the NEOs. The actual number of unearned PSUs that would become earned upon occurrence of the event would be based on the forecasted achievement of performance goals for the remainder of the performance periods and can range from 0% to a maximum of 200% (assuming the highest level of performance) of the target amount of unearned PSUs. The amounts included assume performance at target, without reference to forecasted achievement. The value is based on the closing price of our Common Stock at December 31, 2025 (the last business day of our most recently completed fiscal year).

<sup>3</sup> Calculated as a lump sum payment equal to 250% of Mr. Valdalmudi's target bonus amount that would have been paid for the calendar year and 200% of Messrs. Dodgen's and Perisich's target bonus amount that would have been paid for the calendar year.

<sup>5</sup> Each executive is allowed an accrual of up to five weeks of vacation. For purposes of this table, it was assumed that the full five weeks would be paid upon termination.

Effective March 20, 2025, Mr. McCormick separated from the Company and entered into a Separation and Release of Claims Agreement with the Company dated March 19, 2025 (the "Separation Agreement"). Mr. McCormick was entitled to receive the severance benefits for a termination without cause, as set forth in Section 6(c) of his Amended and Restated Employment Agreement with the Company, dated April 1, 2022. These severance benefits include severance pay of $1,946,880 (200% of Mr. McCormick's then-prevailing annualized base salary); a pro-rated bonus for calendar year 2025 performance that was paid to him in February 2026 in the amount of $468,025; and the Company's payment of premiums for continuation of coverage under the Company's group health plans pursuant to COBRA. In addition, consistent with the terms of his outstanding equity award agreements that apply in connection with a termination without cause, the Separation Agreement provides that Mr. McCormick was entitled to receive accelerated vesting of (i) all outstanding restricted stock units ("RSUs") granted to him on each of March 1, 2023 and March 1, 2024, (ii) a pro-rata portion of RSUs granted to him on March 1, 2025, and (iii) a pro-rata portion of performance stock units granted to him on each of March 1, 2023, March 1, 2024 and March 1, 2025, assuming achievement of target performance thereunder. Under the Separation Agreement, Mr. McCormick was also entitled to up to $10,000 in attorneys' fees for negotiating the Separation Agreement and retention of certain Company-provided computer equipment. The Separation Agreement included customary provisions regarding confidentiality and a release of claims against the Company. The severance benefits under the Separation Agreement were subject to Mr. McCormick's satisfaction of the "Severance Conditions" set forth in the Separation Agreement, including providing and not revoking certain releases thereunder. Under the terms of the Separation Agreement, Mr. McCormick was paid $8,800,402 a portion of which was paid through accelerated vesting of 104,036 RSUs and PSUs previously awarded to Mr. Mr. McCormick. The RSUs and PSUs were valued at $6,703,039 calculated pursuant to the share price at market close on March 20, 2025. The remaining $2,097,363 was paid in cash.

### Pay Ratio Disclosure
We are providing the following information to comply with Section 953(b) of Dodd-Frank and Item 402(u) of Regulation S-K. For 2025, our last completed fiscal year, we determined the ratio of the annual total compensation of our CEO relative to the annual total compensation of our median employee. In determining the median employee, a ranked list was prepared of all of our employees (other than the CEO) based on their W-2 compensation as of December 31, 2025. Such employees include all full-time, part-time, seasonal, and temporary employees. Based on the broad range of our businesses across our service territories, W-2 earnings provide a fixed and fair representation of compensation across our enterprise and thus is an appropriate measure to determine the median employee. No other assumptions, adjustments, or estimates, including any cost-of-living adjustments, were made in identifying the median employee. For purposes of reporting annual total compensation and the ratio of annual total compensation of the CEO to the median employee, both the CEO's and median employee's annual

2026 PROXY STATEMENT PRIMORIS&nbsp;&nbsp;&nbsp;&nbsp; 69

[**Table of Contents**](#TOC)

**Compensation Tables**

total compensation were calculated consistent with the disclosure requirement of executive compensation under the Summary Compensation Table. Since we had multiple CEOs during 2025, we chose to combine the total annual compensation for Mr. Vadlamudi, Mr. King and Mr. McCormick to calculate the ratio.

After applying the methodology described above, our median employee compensation using the Summary Compensation Table requirements was $62,382. Mr. Vadlamudi's, Mr. King's and Mr. McCormick's combined compensation as disclosed in the Summary Compensation Table was $17,488,087. Based on this information, the estimate of the ratio of compensation for our CEO to the median employee for 2025 was 280:1. The 2025 CEO compensation and pay ratio was temporarily inflated by combining Mr. Vadlamudi's, Mr. King's and Mr. McCormick's 2025 compensation. We do not expect this to repeat in 2026. This ratio is specific to our Company and may not be comparable to any ratio disclosed by another company.

### Retirement Plans
We sponsor multiple defined contribution plans for eligible employees not covered by collective bargaining agreements. Our plans include various features such as voluntary employee pre-tax and Roth-based contributions and matching contributions made by us. The plans do not provide any benefits for any executives other than those provided to all employees.

In May 2023, we adopted a non-qualified deferred compensation plan under which eligible Directors and key employees may defer their receipt of certain cash compensation. This plan is an unfunded and unsecured compensation arrangement. Individuals participating in the plan may allocate deferred cash amounts among a group of notional accounts that mirror the gains and losses of various investment alternatives. Generally, participants receive distributions of deferred balances based on predetermined payout schedules or other events.

### Equity Compensation Plans
*Equity Incentive Plans.* In May 2013, the stockholders approved, and the Company adopted the 2013 Equity Incentive Plan. In May of 2023, the stockholders approved, and the Company adopted the 2023 Equity Incentive Plan. Upon the adoption of the 2023 Equity Incentive Plan, awards were no longer granted under the 2013 Equity Incentive Plan, and the only plan pursuant to which the Company may currently grant new equity-based awards is the 2023 Equity Incentive Plan.

The principal purpose of our equity incentive plans is to provide incentives for our officers, employees and consultants, as well as the officers, employees and consultants of any of our subsidiaries. In addition to awards made to officers, employees or consultants, the equity incentive plans permit us to grant options or other equity securities to our Directors.

*2022 Employee Stock Purchase Plan.* In 2022, our stockholders adopted the 2022 Employee Stock Purchase Plan (the "ESPP"), under which eligible full-time employees can purchase shares of our common stock at a discount on a semi-annual basis.

The following table gives information about our Common Stock that may be issued under our existing equity compensation plans, including upon the exercise of options, warrants, and rights, or upon settlement of RSUs, as of December 31, 2025, pursuant to the Company's existing equity compensation plans.

Valuation assumptions used to calculate fair values did not materially differ from those used to calculate fair values at the time of grant as reflected in our Summary Compensation Table amounts.

<sup>3</sup> Pursuant to SEC rules, total stockholder return (TSR) amounts reported assume an initial fixed investment of $100 and that all dividends were reinvested. The Company and peer group total stockholder return for 2021 represents the one-year return for January 1, 2021 to December 31, 2021; for 2022 the returns shown represents the two-year return from January 1, 2021 to December 31, 2023, for 2023 the returns shown represents the three-year return from January 1, 2021 to December 31, 2024; for 2024 the return shown represents the four-year return from January 1, 2024 to December 31, 2024; and for 2025 the return shown represents the five-year return from January 1, 2021 to December 31, 2025.

<sup>4</sup> For purposes of this pay versus performance disclosure, our peer group consists of five companies which are: MasTec, Inc., MYR Group, Inc., Dycom Industries, Inc., Sterling Construction Company, Inc., and Granite Construction, Inc. This Peer Group is consistent with the peer group used in Item 5 of our 2025 Form 10-K.

## STOCKHOLDER PROPOSALS FOR OUR 2027 ANNUAL MEETING
The rules of the SEC establish the eligibility requirements and the procedures that must be followed for inclusion of a stockholder's proposal in a public company's proxy materials. Under those rules, proposals submitted for inclusion in our 2027 proxy materials must be received on or before the close of business on November 20, 2026. Proposals for inclusion in our 2027 proxy materials must comply with the procedures set forth in Rule 14a-8 under the Exchange Act.

Our Amended and Restated Bylaws ("Bylaws") provide that in order for nominations of persons for election to the Board and a proposal of business to be properly brought before an Annual Meeting of Stockholders, it must be either: (1) specified in the notice of the meeting given by us, (2) otherwise brought before the meeting by or at the direction of our Board, or (3) properly brought before the meeting by a stockholder entitled to vote at the meeting who complies with the following notice procedures: (i) the stockholder must give timely notice thereof in writing of the nomination or business to be brought before such meeting to our Secretary, and (ii) such business must be a proper matter for stockholder action under the Delaware General Corporation Law. Our Bylaws provide that to be timely, a stockholder's notice must be delivered to our Secretary at our principal executive offices not less than 45 days prior to the first anniversary of the date on which we first mailed our proxy materials for the preceding year's Annual Meeting. If the date of the subsequent year's Annual Meeting of Stockholders is changed by more than 30 days from the date of the prior year's meeting, notice by the stockholder for the subsequent year's Annual Meeting must be delivered to our Secretary within a "reasonable time" prior to our mailing of the proxy materials for the subsequent year's Annual Meeting of Stockholders. To be properly brought before the 2027 Annual Meeting, notice must be received no later than February 3, 2027. In addition, stockholders who intend to solicit proxies in reliance on the SEC's universal proxy rule for Director nominees submitted under the advance notice requirements of our by-laws must also comply with the additional requirements of Rule 14a-19, including delivery of written notice that sets forth all information required by Rule 14a-19(b) under the Exchange Act no later than March 1, 2027.

Any stockholder who intends to present a proposal or nominate persons for election to the Board at the 2027 Annual Meeting of Stockholders must send notice, with all required information, via standard mail, overnight delivery or other courier service, to Primoris Services Corporation, 2300 N. Field Street, Suite 1900, Dallas, Texas 75201, Attention: Secretary.

2026 PROXY STATEMENT PRIMORIS&nbsp;&nbsp;&nbsp;&nbsp; 75

[**Table of Contents**](#TOC)

## OTHER MATTERS
**This Proxy Statement, being mailed and made available electronically (on our Company website at *www.prim.com*) to stockholders on or about March 20, 2026, is being sent to you by the Board of Directors (the "Board") of Primoris Services Corporation in connection with our 2026 Annual Meeting of Stockholders (the "Annual Meeting"). The Annual Meeting will be held virtually at 9:00 a.m. Central Time, on Thursday, April 30, 2026. You are cordially invited to attend the Annual Meeting and are requested to vote on the proposals described in this Proxy Statement.**

#### Purpose of the Annual Meeting
At the Annual Meeting, our stockholders will vote to elect eight Directors to hold office for a one-year term expiring at the Annual Meeting of Stockholders to be held in 2027, or until a successor is elected and qualified, will vote on an advisory, non-binding basis, on the Company's executive compensation program and will vote to ratify the appointment of Baker Tilly US, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. In addition, management will respond to any questions from stockholders.

#### Materials provided
The Board is sending you this Proxy Statement and the enclosed proxy card in order to solicit your proxy to vote your shares at the Annual Meeting. As a stockholder, you are invited to attend the meeting and are entitled to vote on the items of business described in this Proxy Statement.

#### Annual Meeting attendance
All stockholders as of March 9, 2026 (the "Record Date"), or their duly appointed proxies, may attend the Annual Meeting. You will need to register to be able to attend the Annual Meeting virtually. Gaining admission to the Annual Meeting depends on how your stock ownership is recorded with our transfer agent. If your stock is held in the name of a bank, broker or other holder of record and you plan to attend the Annual Meeting, please obtain a legal proxy from your broker, bank, or other nominee and provide when registering for the virtual meeting. If your stock is registered directly in your name with our transfer agent, you need to provide the control number found on your proxy card when registering for the virtual meeting.

#### Voting at the Annual Meeting
Holders of our common stock ("Common Stock") as of the close of business on the Record Date will be entitled to vote at the Annual Meeting. On the Record Date, there were 54,231,528 shares of Common Stock outstanding, each of which is entitled to one vote with respect to each matter to be voted on at the Annual Meeting. There is no stockholder statutory right of appraisal or dissent with respect to any matters to be voted on at the Annual Meeting.

#### Quorum requirement
The presence at the Annual Meeting, virtually or by proxy, of the holders of a majority of the voting power of all outstanding shares of Common Stock entitled to vote at the Annual Meeting shall constitute a quorum for the transaction of business. Proxies marked as abstaining (including proxies containing broker non-votes) on any matter to be acted upon by stockholders will be treated as present at the meeting for purposes of determining a quorum.

#### Stockholder of record & beneficial owner
All stockholders are invited to attend the Annual Meeting. All shares that have been properly voted and not revoked will be voted at the Annual Meeting. Most of our stockholders hold their shares through a stockbroker, bank or other nominee rather than directly in their own name. As summarized below, there are distinctions between shares held of record and those owned beneficially.

76 &nbsp;&nbsp;&nbsp;&nbsp; PRIMORIS 2026 PROXY STATEMENT

[**Table of Contents**](#TOC)

**Other Matters**

#### Stockholder of Record
If your shares are registered directly in your name with the Transfer Agent, you are considered the stockholder of record, and these proxy materials are being sent directly to you by us. As the stockholder of record, you have the right to grant your voting proxy directly to us or to vote virtually at the Annual Meeting. We have enclosed a proxy card for you to use.

Voting electronically at the Annual Meeting—You may vote your shares electronically at the Annual Meeting by visiting the link provided during the Annual Meeting while the polls are open and providing the control number found on your proxy card. Even if you plan to attend the Annual Meeting, we recommend that you vote your shares in advance as described below so that your vote will be counted if you later decide not to attend the Annual Meeting.

Voting without attending the Annual Meeting—Please complete and properly sign and date the accompanying proxy card and return it to the Transfer Agent in the accompanying pre-addressed envelope.

Changing your vote after returning your proxy card—You can revoke your proxy before it is exercised at the meeting by:

● delivering written notice of revocation of the proxy to our Secretary prior to the Annual Meeting;

● executing and delivering a later dated proxy card to our Secretary; or

● attending and voting electronically at the Annual Meeting.

#### Beneficial Owner of Shares
If your shares are held in a stock brokerage account, by a bank or other nominee, you are considered the beneficial owner of shares held in "street name" and these proxy materials are being forwarded to you by your broker, bank or nominee who is considered, with respect to your shares, the stockholder of record. As the beneficial owner, you have the right to direct the stockholder of record how to vote your shares. Your broker, bank or nominee has enclosed a voting instruction card for your use.

Voting without attending the Annual Meeting—Please follow the instructions provided by your broker, bank or nominee. You may vote by mail by completing, signing and dating the voting instruction card provided by your broker, bank or nominee and mailing the card to such entities in the accompanying pre-addressed envelopes.

Changing your vote after returning your proxy card—You may submit new voting instructions by contacting your broker, bank or other nominee. You may also vote electronically at the Annual Meeting by following the instructions in the next section below.

Voting electronically at the Annual Meeting—You may vote electronically at the Annual Meeting by visiting the link provided during the Annual Meeting while the polls are open and providing your virtual control number assigned to you in the registration confirmation email.

#### Required votes to approve each item
Each outstanding share of Common Stock is entitled to one vote on each proposal at the Annual Meeting. All matters require the existence of a quorum at the Annual Meeting. All proposals require an affirmative vote of the majority of shares virtually present at the Annual Meeting or represented by proxy and entitled to vote on the subject matter, other than the election of Directors, which is determined by a plurality of shares virtually present at the Annual Meeting or represented by proxy. The individual receiving the largest number of votes for each position will be elected.

In voting on Proposal 1, the election of Directors, you may vote "FOR" the nominee or your vote may be "WITHHELD" with respect to the nominee. In voting on any other proposal, you may vote "FOR", "AGAINST", or "ABSTAIN". A properly executed proxy marked "ABSTAIN" with respect to any other proposal will not be voted, although it will be counted for purposes of determining whether there is a quorum. An abstention will have the effect of a negative vote on that matter. If you are a beneficial owner, shares represented by broker non-votes (when the broker indicates they do not have their customer's direction on how to vote, nor has discretionary authority on how to vote) will be counted in determining whether there is a quorum, but will not be counted as votes cast on any proposal where the broker indicated they do not have discretionary voting authority. Brokers and other nominees who are New York Stock Exchange members are expected to have discretionary voting power only for Proposal 3, the ratification of Baker Tilly US, LLP as our independent registered public accounting firm, but not for any other proposals. As a result, if you do not provide specific voting instructions to your record holder, New York Stock Exchange rules will allow the record holder to vote only on Proposal 3, and not on Proposals 1 or 2.

**Other Matters**

#### Inspector of elections
Our Executive Vice President, Chief Legal and Administrative Officer and Secretary, John M. Perisich, will act as Inspector of Elections and oversee the voting results. The Inspector of Elections will also determine the presence of a quorum.

#### Voting results of the Annual Meeting
We will announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on a Form 8-K filing with the Securities and Exchange Commission ("SEC") within four business days of the Annual Meeting.

● FOR Proposal No. 1, to elect each of the eight director nominees to hold office for a one-year term expiring at the Annual Meeting of Stockholders to be held in 2027 or until a successor is elected and qualified.

● FOR Proposal No. 2, to approve, in an advisory, non-binding vote, the Company's named executive officer compensation.

● FOR Proposal No. 3, to ratify the appointment of Baker Tilly US, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

Unless you give other instructions on your proxy card, the individual(s) named as proxy holder on the proxy card will vote in accordance with the recommendations of the Board.

#### Expense of soliciting proxies
We will pay the costs for the solicitation of proxies, including the cost of preparing and mailing this Proxy Statement. Proxies are being solicited primarily by mail, but the solicitation by mail may be followed-up by solicitation in person, or by telephone or facsimile, by our regular employees without additional compensation for such proxy solicitation activity or by a proxy solicitation firm. We will reimburse brokers, banks and other custodians and nominees for their reasonable out-of-pocket expenses incurred in sending proxy materials to our stockholders.

**Other Matters**

#### Other Information
We are not aware of any matters other than those discussed in the foregoing materials contemplated for action at the 2026 Annual Meeting. The person(s) named in your proxy will vote in accordance with the recommendation of the Board on any other matters incidental to the conduct of, or otherwise properly brought before, the Annual Meeting. Discretionary authority for them to do so is contained in the proxy.

SEC rules permit companies, brokers, banks or other intermediaries to deliver a single copy of this Proxy Statement and Annual Report to households at which two or more stockholders reside. This practice, known as "householding," is designed to reduce duplicate mailings and save significant printing and postage costs as well as natural resources. Stockholders sharing an address who have been previously notified by their broker, bank or other intermediary and have consented to householding will receive only one copy of our Proxy Statement and Annual Report. If you would like to opt out of this practice for future mailings and receive separate Proxy Statements and Annual Reports for each stockholder sharing the same address, please contact your broker, bank or other intermediary.

Stockholders sharing an address that are receiving multiple copies of the Proxy Statement or Annual Report can request delivery of a single copy of the Proxy Statement or Annual Report by contacting their broker, bank or other intermediary or sending a written request to the Company at Primoris Services Corporation, 2300 N. Field Street, Suite 1900, Dallas, Texas 75201, Attention: Investor Relations, or by contacting us at (214) 740-5600. You may also obtain a separate Proxy Statement or Annual Report without charge by sending a written request to the above address. We will promptly send additional copies of the Proxy Statement or Annual Report upon receipt of such request.

Our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, is being mailed to all stockholders of record with this Proxy Statement. The Annual Report on Form 10-K does not constitute, and should not be considered, a part of this proxy solicitation material.

A copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the SEC is available without charge upon written request to:

Primoris Services Corporation

2300 N. Field Street, Suite 1900
