Notice of the 2022
Annual Meeting of Stockholders

March 25, 2022

TO OUR STOCKHOLDERS:

The 2022 Annual Meeting of Stockholders of Primoris Services Corporation, a Delaware corporation, will be held on Wednesday, May 4, 2022, at 9:00 a.m., Central Time, on the 8th floor of our office building at 2300 N. Field Street, Dallas, Texas 75201. To accommodate ongoing public health issues surrounding the COVID-19 virus, we are also providing virtual access to the meeting.

Only stockholders that owned shares of our Common Stock at the close of business on March 14, 2022 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 and will also be available at the Annual Meeting.

At the Annual Meeting, we will consider the following proposals, which are described in detail in the accompanying Proxy Statement:

to elect nine directors to hold office for a one-year term expiring at the Annual Meeting of Stockholders to be held in 2023 or until a successor is elected and qualified;

to ratify the appointment of Moss Adams LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022;

to approve the Employee Stock Purchase plan; and

to transact such other business as may properly come before the Annual Meeting and all adjournments or postponements thereof.

Attending the Annual Meeting Virtually

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. However, you will bear any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies. 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, especially as physical attendance at meetings has dwindled. 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.

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 be submitted via the meeting website either in advance of or during the Annual Meeting.

TABLE OF CONTENTS

Proxy Statement Summary

CORPORATE
PROFILE

Primoris Services Corporation is a leading specialty contractor providing critical infrastructure services to the utility, energy/renewables and pipeline services markets throughout the United States and Canada. The Company supports a diversified base of blue-chip customers with engineering, procurement, construction, and maintenance services. A focus on multi-year master service agreements and an expanded presence in higher-margin, higher-growth markets such as utility-scale solar facility installations, renewable fuels, electrical transmission and distribution systems and communications infrastructure have also increased the Company’s potential for long-term growth.

OUR
HISTORY

The Company’s roots go back to 1960 with the founding of ARB, Inc., a Bakersfield, California, pipeline construction company. ARB, Inc. met the growing demand for energy infrastructure that accompanied the mid-century oil boom in the west and quickly established a reputation for great quality and reliability. ARB, Inc.’s work and reputation fueled significant growth and laid the foundation for Primoris, which is today one of the largest specialty contractors in the country.

Primoris was formed in 2003 and it became a Delaware public company in July 2008 when it merged with a special purpose acquisition company (a non-operating shell company). Since that time, the Company has grown organically and through strategic acquisitions, which has allowed it to expand its service capabilities and geographic footprint. Primoris trades on Nasdaq under the symbol PRIM.

OUR
PEOPLE

Because Primoris believes that its employees are the most valuable resource in successfully completing its projects, the Company employs a dynamic mix of people to create the strongest company possible. As of December 31, 2021, Primoris employed 1,925 salaried employees and 8,885 hourly employees. (The total number of hourly personnel employed varies based on the volume of work in progress.)

One of Primoris’ core values is to provide a safe and healthy workplace for its people. Safety, industrial hygiene, and loss prevention are the direct responsibility of all members of management, and employees receive the appropriate training, equipment, and other resources necessary to complete assigned tasks in a safe and efficient manner. Primoris prides itself on above-average workplace safety. Total Recordable Incident Rate (“TRIR”) tracks the total number of workplace safety incidents, reported as the number of workplace safety incidents per 100 full-time workers during a one-year period. For the year ended December 31, 2021, the Company’s TRIR was 0.49, compared to an industry average of 2.7 per the U.S. Bureau of Labor construction industry statistics.

In response to the COVID-19 pandemic, Primoris maintained practices throughout 2021 to protect its employees and communities and to comply with client requirements and government regulations. These included providing additional personal protective equipment, requiring on-site health screenings, following proper social distancing practices, offering office employees flexible, remote working options, and other actions as appropriate.

Proxy Statement Summary

2021 Business Highlights

	Primoris prevailed over weather events and supply chain and permitting challenges, while maintaining its high standards for quality and achieving its best-ever safety performance in 2021. The Company established its footing in the communications market and expanded its presence in the renewables market and while doing all that, the Company maintained a solid performance in its traditional utility, energy, pipeline and heavy civil markets. Primoris wrapped up the year with a strong fourth quarter, reflecting the momentum that we built throughout 2021.

TABLE OF CONTENTS

Proxy Statement Summary

Environmental Social Governance Highlights

Primoris Services Corporation (“Primoris” or the “Company”) believes that proactive oversight of Environmental, Social and Governance (“ESG”) 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.

Primoris is proud of our record on environmental, social and governance issues. We formalized our focus on these areas in 2020 with the formation of an Environmental, Social & Governance Committee with the support of our Board of Directors and management team. During 2021, we made progress in each area.

	ENVIRONMENT
We are committed to reducing or eliminating negative environmental impacts wherever practicable. More than that, we are actively seeking projects that contribute to a lower-carbon future. In 2021 this included $1,246 million in new solar projects with targeted completion in 2022 and 2023. In addition, we have taken on several projects that support the production of biofuels and are working with clients to explore options involving hydrogen and carbon capture technology. In terms of our own environmental impacts, we have implemented energy-efficient technology in many of our own facilities and are now working with clients to reduce and offset the carbon footprint of solar energy construction projects.		$1,246M in new solar projects announced in 2021

	SOCIAL
Our primary social responsibility focus is on diversity and inclusion both within the Primoris workforce and in our supply chain. In 2020, we established a Diversity and Inclusion Committee that reports to the Chief Executive Officer. The committee promotes awareness of diversity and inclusion issues and assists in the development of initiatives that drive increased diversity for Primoris. We have standardized diversity and anti-harassment training across business units and are now tracking female and minority representation across the organization. Diversity is a required element in our procurement and subcontracting decision-making. We maintain a Supplier Diversity database that provides the information to manage our ongoing relationship development with small and diverse companies. Our proactive approach includes developing key suppliers and creating strategic alliances with various Diverse Business Enterprise (DBE) suppliers. Our approach increases diversity while creating long-term value for the supply chain and our core business.		45% of the overall workforce identified as racial minority 10% of the overall workforce identified as female

Proxy Statement Summary

	GOVERNANCE
A governance refresh undertaken in 2019 included publication of our Corporate Governance Guidelines and Code of Conduct. Additional actions taken by the Board included Board declassification, establishment of a mandatory board retirement age of 75, creation of a director stock ownership requirement, and prohibition of hedging and short-selling with Primoris stock. Maintaining security of information and mitigating against cyber risk is vital to maintaining our proprietary information and the trust of our customers and employees. We have several layers of protections in place, all overseen by our Security Steering Committee (“SSC”) that regularly informs the Executive Leadership Team, our Audit Committee, and our Board of Directors. Senior leadership briefs the Board on information security on a quarterly basis. The Audit Committee of the Board of Directors has compliance oversight for matters of Information Technology security risks including cybersecurity risks. Primoris’ cybersecurity efforts ensure the safety and security of its customers and employees. The SSC is comprised of cybersecurity strategy experts and maintains the policies and awareness of threats and vulnerabilities on an ongoing basis. Further, the SSC educates employees regarding cybersecurity using security awareness training, security bulletins and phishing simulations to reinforce training on a quarterly basis. Cybersecurity training is made available to all employees through an online training portal. Primoris conducts vulnerability scans and penetration testing and works with a third-party to perform yearly baseline assessments of the cyber program that measures improvement and evaluates the Company’s incident response plan and related solutions. The National Institute of Science and Technology (NIST) Cybersecurity Framework is the basis of the Company’s cybersecurity framework, and on a regular basis, the Audit Committee of the Board of Directors reviews and discusses any key issues related to information technology cybersecurity risks and management programs.		4.2 years average tenure of Primoris board members

PROPOSAL 1 – ELECTION OF DIRECTORS

General Information

What am I being asked to vote on?

You are being asked to vote to elect nine 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 Nasdaq listing rules.

The Company has a mandatory retirement policy in its Corporate Governance Guidelines which requires that no person older than 75 years may be appointed to or nominated for a director position. The Company has one member, Robert A. Tinstman, who meets this criteria and is not standing for re-election at the 2022 Annual Meeting of the stockholders. Therefore, Mr. Tinstman’s term will end at the conclusion of the Annual Meeting. The Board engaged a third-party firm to search for a candidate and has nominated Michael E. Ching to fill the vacancy. Seven of these nine director nominees are independent as determined under Nasdaq listing rules.

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 2023 Annual Meeting, or until their successors are elected and qualified 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 2023 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

Our Board of Directors recommends a vote FOR the election of each of the nine director nominees as directors to hold office until our annual meeting of stockholders to be held in 2023 or until their respective successors are duly elected and qualified or upon their earlier death, resignation or removal.

PROPOSAL 3 – APPROVAL OF THE EMPLOYEE STOCK PURCHASE PLAN.

General Information

What am I being asked to vote on?

You are being asked to vote to approve the adoption of the Company’s 2022 Employee Stock Purchase Plan.

Summary

We are asking the stockholders to approve a new employee stock purchase plan, the Primoris Services Corporation Employee Stock Purchase Plan (the “2022 Employee Stock Purchase Plan”). Our Board has determined that it is in the best interests of our company and stockholders to have an employee stock purchase plan and has adopted the 2022 Employee Stock Purchase Plan, subject to approval from the stockholders at the Annual Meeting. If approved by our stockholders, the 2022 Employee Stock Purchase Plan will become effective May 4, 2022, and does not expire, unless terminated in accordance with the 2022 Employee Stock Purchase Plan.

Description of the 2022 Employee Stock Purchase Plan

The following is a summary of the principal features of the 2022 Employee Stock Purchase Plan and its operation. However, this summary is not a complete description of all of the provisions of the 2022 Employee Stock Purchase Plan and is qualified in its entirety by the specific language of the 2022 Employee Stock Purchase Plan. A copy of the 2022 Employee Stock Purchase Plan is provided as Appendix A to this proxy statement.

Purpose. The purpose of this 2022 Employee Stock Purchase Plan is to provide employees of the Company and its designated subsidiaries with an opportunity to purchase the Company’s Common Stock through one-time or accumulated contributions. The 2022 Employee Stock Purchase Plan is not intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code of 1986, as amended (the “Code”).

Shares Available for Issuance. If our stockholders approve this proposal, a total of 1,000,000 shares of the Company’s Common Stock will be reserved for issuance under the 2022 Employee Stock Purchase Plan.

Plan Administration. The “Administrator” of the 2022 Employee Stock Purchase Plan shall be the Compensation Committee of the Board (or any successor committee) or such other committee as designated by the Board. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of the 2022 Employee Stock Purchase Plan, to designate separate offerings under the 2022 Employee Stock Purchase Plan, to determine eligibility, to adjudicate all disputed claims filed under the 2022 Employee Stock Purchase Plan and to establish such procedures that it deems necessary for the administration of the 2022 Employee Stock Purchase Plan. The Administrator is specifically authorized to adopt rules and procedures regarding eligibility to participate, the definition of Compensation, handling of contributions, making of contributions to the 2022 Employee Stock Purchase Plan (including in forms other than payroll deductions), establishment of bank or trust accounts to hold contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates that vary with applicable local requirements.

Eligibility. All employees, including our executive officers, and employees of our designated subsidiaries of the Company that are designated by the Administrator to participate in the 2022 Employee Stock Purchase Plan, are eligible to participate in the 2022 Employee Stock Purchase Plan if they are employed by us or a participating subsidiary for at least 20 hours per week and more than five months in any calendar year. As of March 21, 2022, approximately 10,000 employees of the Company and its designated subsidiaries would have been eligible to participate in the 2022 Employee Stock Purchase Plan if it had been in effect on such date.

2022 PROXY STATEMENT

TABLE OF CONTENTS

Proposal 3 – Approval of the Employee Stock Purchase Plan

Offering Periods. Unless otherwise determined by the Administrator, the first offering period under the 2022 Employee Stock Purchase Plan will have a duration of approximately 30 days, commencing on the second full trading day following the filing of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31 of each year but in no cases can extend beyond March 31st of the period or year, and the second offering period will have a duration of approximately 30 days, commencing on the second full trading day following the filing of the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ended June 30th of each year.

Contributions. Our 2022 Employee Stock Purchase Plan permits participants to purchase shares in an amount specified by such participant for such offering period or to the extent permitted by the Administrator, have after-tax payroll deductions made on each pay day during the offering period in an amount equal to at least 1% but not exceeding 15% of the participant’s compensation (or such other percentage of compensation as determined by the Administrator in its sole discretion). The minimum permissible contribution by any participant for an offering period shall be $500. Non-payroll contributions must be made in a manner authorized by the Administrator no later than three calendar days prior to the exercise date of such purchase period, unless sooner terminated by the participant; provided, however, that if the participant does not deliver such non-payroll contributions by the deadline, the participant will be deemed to have withdrawn from participation for such offering period.

Change of Payroll Deduction. A participant may only decrease or increase the percentage of their payroll deductions during an offering period in accordance with the procedures established and communicated by the Administrator in advance of an offering period.

Withdrawal; Termination of Employment. A participant may withdraw all, but not less than all, the contributions credited to his or her notional account and not yet used to exercise his or her option under the 2022 Employee Stock Purchase Plan at any time by (a) submitting to the Company’s Finance department (or its delegate) a written notice of withdrawal in the form determined by the Administrator for such purpose or (b) following an electronic or other withdrawal procedure determined by the Administrator. A participant will automatically be withdrawn from an offering period upon a termination of employment with the Company prior to a purchase date, and a terminated participant’s unused payroll deductions will be refunded.

Purchase Price. The purchase price means an amount equal to 90% of the market value of a share of Common Stock at the close of the trading day the day prior to the enrollment date or at the close of the trading day the day prior to the exercise date, whichever is lower.

Non-Transferability. Neither contributions credited to a participant’s notional account nor any rights with regard to the exercise of an option or to receive shares of Common Stock under the 2022 Employee Stock Purchase Plan may be assigned, transferred, pledged or otherwise disposed of in any way by the participant.

Certain Adjustments. In the event that any dividend or other distribution, recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the corporate structure of the Company affecting the Common Stock occurs, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the 2022 Employee Stock Purchase Plan, will, in such manner as it may deem equitable, adjust the number and class of Common Stock that may be delivered under the 2022 Employee Stock Purchase Plan, the purchase price per share and the number of shares of Common Stock covered by each option under the 2022 Employee Stock Purchase Plan that has not yet been exercised.

Merger or Change in Control. In the event of a merger, sale or other similar corporate transaction involving the Company, each outstanding option will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option, the offering period with respect to which such option relates will be shortened by setting a new exercise date on which such offering period shall end. The new exercise date will occur before the date of the Company’s proposed merger, sale or other similar corporate transaction.

Amendment or Termination. The Administrator, in its sole discretion, may amend, suspend, or terminate the 2022 Employee Stock Purchase Plan, or any part thereof, at any time and for any reason. If the 2022 Employee Stock Purchase Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding offering periods either immediately or upon completion of the purchase of shares of Common Stock on the next exercise date.

Upon its approval by the stockholders, the 2022 Employee Stock Purchase Plan will continue until terminated in accordance with the 2022 Employee Stock Purchase Plan.

Federal Income Tax Consequences.

The following summary is intended only as a general guide to the current U.S. federal income tax consequences of participation in the 2022 Employee Stock Purchase Plan and does not attempt to describe all possible federal or other

2022 PROXY STATEMENT

Proposal 3 – Approval of the Employee Stock Purchase Plan

tax consequences of such participation or tax consequences based on particular circumstances. Furthermore, the tax consequences are complex and subject to change, and a participant’s particular situation may be such that some variation of the described rules is applicable.

Our 2022 Employee Stock Purchase Plan is not intended to qualify as an “employee stock purchase plan” under Section 423 of the Code. Under the 2022 Employee Stock Purchase Plan, shares of Primoris Common Stock may be purchased by eligible participants, using after tax contributions, at a 10% discount.

The participant will recognize ordinary taxable income on the purchase date in an amount equal to the difference between the fair market value of the shares of Common Stock purchased on the purchase date and the purchase price paid for the shares of Common Stock (i.e. the “discount”). Upon subsequent resale of the shares of Common Stock, the difference between the sale price and the fair market value on the purchase date will be treated either as a capital gain or loss. The holding period to determine whether the capital gain (or loss) is a long- or short-term capital gain (or loss) will commence on the day after the purchase date when the Common Stock is acquired.

Registration with the Securities and Exchange Commission. If the 2022 Employee Stock Purchase Plan is approved by the Company’s stockholders, the Company will file a registration statement with the Securities and Exchange Commission pursuant to the Securities Act of 1933 covering the shares of the Company’s Common Stock authorized for issuance under the 2022 Employee Stock Purchase Plan.

New Plan Benefits. Benefits and purchases of shares of our Common Stock under the 2022 Employee Stock Purchase Plan depend on elections made by employees as to the amount of payroll deductions or other contributions to be taken per plan period, as well as on the fair market value of our Common Stock on dates in the future. As a result, it is not possible to determine the benefits that will be received by executive officers and other employees in the future under the 2022 Employee Stock Purchase Plan.

The number of shares of our Common Stock that can be purchased by each employee will vary based on the fair market value of the Common Stock on the day prior to the enrollment date or the close of the trading day the day prior to the exercise date. Accordingly, the dollar value and the number of shares that may be purchased in the future pursuant to the 2022 Employee Stock Purchase Plan are not currently determinable.

Fair Market Value. As of March 14, 2022, the closing price of the Company’s Common Stock on Nasdaq was $26.83.

Recommendation of the Board of Directors

Our Board of Directors recommends a vote FOR the approval of the 2022 Employee Stock Purchase Plan.

Corporate Governance

Board Independence

The listing standards of Nasdaq 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 which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

To assist it in making independence determinations, the Board has adopted independence standards, which include the standards required by Nasdaq for independent directors. Under these standards, a director is not independent if:

		• The director is, or has been within the last three years, one of our or our subsidiaries’ employees, or the director has an immediate family member who is, or has been within the last three years, one of our executive officers;
		• The director has received, or has an immediate family member who has received, during any twelve-month period within the last three years, more than $120,000 in compensation from us (other than compensation for Board or Committee service, compensation to a family member who is an employee but not an executive officer, or benefits under a tax-qualified retirement plan or non-discretionary compensation);
		• The director is, or has a family member that is, a partner in, or a controlling stockholder or an executive officer of, any organization to which we made, or from which we received, payments for property or services in the current year or in any of the last three years, that exceed 5% of the recipient’s consolidated gross revenues for that year or $200,000, whichever is greater, other than payments arising solely from investments in our securities or payments under non-discretionary charitable contribution matching programs;
		• The director, or an immediate family member, is currently employed, or has been employed within the last three years, as an executive officer of another company where any of our present executive officers serves or has served on that company’s compensation committee; or
		• The director is, or has a family member that is, a current partner of our outside auditor, or was a partner or employee of our outside auditor who worked on our audit at any time during any of the past three years.

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, Cook, McCallister, Rodriguez, Schauerman and Tinstman and Mss. Mashinski and Wagner are independent.

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 2021, the Board held a total of 11 meetings, the Audit Committee held four meetings, the Compensation Committee held five meetings, the Nominating and Corporate Governance Committee held five 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 2021.

Separate
Chairman
and CEO
Roles

The Board has separate 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. In May 2010, Mr. Cook was appointed by the Board as the Lead Director, responsible for chairing the Board meetings in the absence of the Chairman, chairing executive sessions of independent Directors, acting as the principal liaison between the Chairman and the independent Directors and serving as the contact Director for stockholders. 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 at this time and allows Mr. McCormick to focus primarily on the operations and management of the Company, while leveraging Mr. King’s experience to lead the Board.

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 act on the recommendations in a vote in which only independent Directors participate and which takes place during executive sessions of the 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:

[MISSING IMAGE: tm2130832d2-fc_oversightpn.jpg]

Selection of Board Nominees

The Board believes that the Board, as a whole, should include individuals with a diverse 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 representing a diverse background (including gender, race, ethnicity, and age) and to include in its overall composition an array of targeted skills that complement one another rather than requiring each director to possess the same skills, perspectives and interests. Accordingly, the Board and the Nominating and Corporate Governance Committee consider the qualifications of directors and director nominees both individually and in the broader context of the Board’s overall composition and the Company’s current and future needs.

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. To that end, our Corporate Governance Guidelines provide that directors may not stand for re-election if the election occurs after they reach the age of 75. In addition, 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 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:

		• Experience in corporate management;
		• Experience in our industry;
		• Experience as a board member or officer of a publicly held company;
		• Experience in financial and accounting matters;
		• Diversity of expertise and experience in substantive matters related to our business; and
		• Practical and mature business judgment.

The Nominating and Corporate Governance Committee has adopted its own 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, in-person interviews, and telephone interviews. 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. In addition, the Company periodically engages a third-party consulting firm to conduct a comprehensive Board effectiveness review.

Code of Conduct

The Company has a Code of Conduct that complies with the rules and regulations adopted by the SEC and Nasdaq 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.primoriscorp.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:

		• Honest and ethical conduct;
		• Avoidance of conflicts of interest;
		• Full, fair, accurate, timely and understandable disclosure in reports and documents that we file with, or submit to, the SEC and in our other public communications;
		• Compliance with applicable governmental laws and regulations and stock exchange rules;
		• Prompt internal reporting of violations of the Code of Conduct to an appropriate person or persons identified in the Code of Conduct; and
		• Accountability for adherence to the Code of Conduct.

Director Access To Officers, Employees, and Information

Directors have full and free access to officers, employees and the books and records of the Company. The Directors are expected to use their judgment to ensure that any such contact is not disruptive to the business operations of the Company. Non-Board member employees may be invited to attend all or portions of Board and/or Committee meetings.

Policy Regarding Director Attendance at Annual Meetings of Stockholders

Directors are strongly encouraged to attend our Annual Meetings of Stockholders. All the Directors were in attendance at the 2021 Annual Meeting.

Stockholder Communications with the Board of Directors

Stockholders may communicate with any of our Directors, either individually or as a group, by writing to them at Primoris Services Corporation, c/o Secretary, 2300 N. Field Street, Suite 1900, Dallas, Texas 75201. Please specify to whom your correspondence should be directed. The Secretary will promptly forward all correspondence to the Board or any specific committee member, as indicated in the correspondence, except for mass mailings, job inquiries, surveys, business solicitations or advertisements, or patently offensive or otherwise inappropriate material. Our Secretary may forward certain correspondence, such as product-related or service-related inquiries, elsewhere within the Company for review and possible response.

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, 2021 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, 2021. 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, 2021 and issuing an opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021. 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 Nasdaq 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, 2021 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 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 2019, the Compensation Committee approved an Incentive Compensation Plan that established a more formulaic annual incentive calculation and an increased emphasis on equity awards within the total compensation structure. We believe that our compensation practice will further enhance value for our stockholders.

Shareholder “Say-on-Pay” Vote

[MISSING IMAGE: tm2130832d2-pc_sayonpaypn.jpg]

At our Annual Meeting of Stockholders in May 2020, 85.2% of votes cast on our advisory vote on executive compensation (“say-on-pay proposal”) were voted in favor of the proposal, which our Compensation Committee has considered in designing and granting compensation to our NEOs. Consistent with the vote of our shareholders at our 2017 Annual Meeting on the proposed frequency for seeking advisory votes on executive compensation, we submit a say-on-pay proposal to a shareholder vote every three years.

Executive Compensation

Incentive Compensation Plan

The Company’s incentive compensation plan (“ICP”) for senior leadership and executives is designed to provide annual awards payable in 75% cash and 25% equity in the form of RSUs. The total annual award earned is comprised of two components:

[MISSING IMAGE: tm2130832d2-fc_incentivepn.jpg]

An eligible NEO that begins employment during the performance year will generally have to wait a year to enter the ICP, 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 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 ICP is calculated as a percentage of such NEO’s base salary earned during the year (the “ICP Target”), which is then multiplied by the weighted achievement percentage associated with the Company performance metrics, as set forth in the following calculation:

2022 PROXY STATEMENT

PRIMORIS | 45

TABLE OF CONTENTS

Executive Compensation

The Compensation Committee established the following ICP Targets for each NEO for the 2021 performance year:

Name	Base Salary Earned			ICP Target (% of Base Salary)		ICP Target Amount
Thomas E. McCormick		$	737,019		225%		$	1,658,293
Kenneth M. Dodgen			453,960		175			794,430
John F. Moreno Jr.			552,212		175			966,371
John M. Perisich			497,029		175			869,801

Net Income Component

The Net Income Component of the ICP is based on annual net income. A payout occurs only if actual net income 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 2021 performance year, NEOs could earn awards for this component of the ICP as follows (when performance falls between the designated payout points above the threshold amount, the awards are determined by interpolation):

If Net Income is (in millions)	% of Target	Achievement %
Below $94.9 (threshold)	Less than 75%		0%
$94.9	75%		20%
$126.5 (target)	100%		70%
$145.5	115%		100%
Above $145.5 (maximum)	Greater than 115%		120%

For the 2021 performance year, the Compensation Committee established a target ICP net income of $126.5 million. The Compensation Committee concluded that actual ICP net income for the performance year was $118.4, which represents approximately 93.6% of the target and an achievement percentage of 57.2%.

The following table details the actual payouts associated with the ICP Earnings per Share component:

Name	ICP Target Amount			ICP Earnings per Share Component		Achievement Percentage		Multiplier		ICP Earnings per Share Award Earned(1)
Thomas E. McCormick		$	1,658,293		60%		57.2%		75%		$	426,949

John M. Perisich			869,801		60		57.2		75			223,941

Calculations may not be exact due to the rounding of the achievement percentage input used in the calculation

New Business Generated Component

The New Business Generated Component of the ICP is based on new contracts executed where scope is adequately defined and revenue generated under contracts where scope is not adequately defined during the 2021 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 2021 performance year, NEOs could earn awards for this component of the ICP 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)	% of Target	Achievement %
Below $3,172.1 (threshold)	Less than 75%		0%

Calculations may not be exact due to the rounding of the achievement percentage input used in the calculation

Cash Management Component

The Cash Management Component of the ICP is based on the ability of the Company to manage cash during the 2021 plan year. 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. 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 2021 performance year, NEOs could earn awards for this component of the ICP 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)	% of Target	Achievement %
Above 87.5 (threshold)	Greater than 125%		0%
87.5	125%		20%
70 (target)	100%		70%
59.5	85%		100%
Below 59.5 (maximum)	Less than 85%		120%

For the 2021 performance year, the Compensation Committee established a target ICP cash management of 70 days. The Compensation Committee concluded that actual ICP cash management for the performance year was 56 days, which represents approximately 80.0% of the target and an achievement percentage of 120.0%.

The following table details the actual payouts associated with the ICP Cash Management component:

Name	ICP Target Amount			ICP Cash Management Component		Achievement Percentage		Multiplier		ICP Cash Management Award Earned
Thomas E. McCormick		$	1,658,293		10%		120.0%		75%		$	149,246

John M. Perisich			869,801		10		120.0		75			78,282

Safety Performance Component

The final component of the ICP is based on 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. TRIR is defined as the number of work injuries in the performance year multiplied by 200,000 divided by reportable hours worked. 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 2021 performance year, NEOs could earn awards for this component of the ICP as follows (when performance falls between the designated payout points below the threshold amount, the awards are determined by interpolation):

If TRIR is	% of Target	Achievement %
Above 0.75 (threshold)	Greater than 125%		0%
0.75	125%		20%
0.60 (target)	100%		70%
0.51	85%		100%
Below 0.51 (maximum)	Less than 85%		120%

For the 2021 performance year, the Compensation Committee established a target ICP TRIR of 0.60. The Compensation Committee concluded that actual ICP TRIR for the performance year was 0.49, which represents approximately 82.1% of the target and an achievement percentage of 120.0%.

The following table details the actual payouts associated with the ICP Safety component:

Name	ICP Target Amount			ICP Safety Component		Achievement Percentage		Multiplier		ICP Safety Award Earned
Thomas E. McCormick		$	1,658,293		5%		120.0%		75%		$	74,623

John M. Perisich			869,801		5		120.0		75			39,141

Discretionary Amounts

Under the ICP, 25% of each NEOs total annual award is discretionary, as evaluated and approved by the Compensation Committee. There is not a requirement that there be a relationship between the measurable performance and the discretionary performance. For example, a discretionary performance bonus could be awarded even if most, or all, of the measurable performance goals were not attained. Similarly, an excellent measurable performance would not necessarily result in awarding a maximum discretionary performance amount.

The following table lists the discretionary performance award amounts for 2021 and 2020.

Name	2021 Discretionary Performance Amount			2020 Discretionary Performance Amount			$ increase (decrease)
Thomas E. McCormick		$	352,387		$	349,142		$	3,245
Kenneth M. Dodgen			178,747			175,375			3,372

John M. Perisich			206,578			200,227			6,351

Equity Awards

Under the ICP, all of the NEOs are paid their total awards (measurable and discretionary) 75% in cash and 25% in RSUs. The RSUs generally vest over three years in equal annual installments, as long as the NEO is employed by the Company, subject to accelerated vesting upon the reporting person’s termination without cause, death, disability, or retirement from the Company. The number of RSUs are determined using a 25% discount to the average December 2021 closing price for Primoris shares.

Executive Compensation

The following table shows the total RSUs earned by each of the NEOs under the ICP in 2021 and granted in March 2022:

Kenneth M. Dodgen		8,774
John F. Moreno, Jr		10,332
John M. Perisich		9,759

During 2021, the Compensation Committee further evaluated the equity compensation of our NEOs compared to our peer companies. Based on this evaluation, it was determined that additional equity compensation should be awarded to each of our NEOs to more closely align with the equity compensation of our peer companies. As a result, each NEO received an additional one-time RSU grant in June 2021.

Other Compensation Items

Stock Ownership Guidelines

In August 2019, 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
	Chief Executive Officer			3x base salary
	Other Executive Officers			2x 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:

		• 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;
		• shares held in trust for the benefit of the officer or his immediate family members;
		• shares purchased on the open market;
		• shares purchased or awarded through the Company’s Long-term Retention Plan (the “LTR Plan”);
		• vested and unvested time-based restricted stock or restricted stock units; and
		• dividend equivalent shares.

Anti-Hedging 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 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.

Pay Recoupment (Clawback) Policy

The Company employs the following clawback policy that applies to NEOs. If the Company is required to prepare an accounting restatement due to the material noncompliance of the Company as a result of misconduct with any financial reporting requirement under the securities laws, any participant who knowingly or through gross negligence engaged in the misconduct, or who knowingly or through gross negligence failed to prevent the misconduct, and any participant who is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002, shall reimburse the Company for the amount of any payment in settlement of an award earned or accrued during the twelve (12) month

period following the first public issuance or filing with the SEC (whichever first occurred) of the financial document embodying such financial reporting requirement. The Board has sole discretion to make any and all decisions under this policy.

The SEC has proposed new rules that could affect the Company’s clawback policies. When the rules are finalized, the Company will update its policies to be in compliance with such rules.

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:

		• 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 as measured under several financial and operational performance metrics. Additionally, RSUs generally vest over three years in equal annual installments, 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.
		• The Compensation Committee believes the financial and operational performance measures for determining cash and equity awards earned under our ICP 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.
		• 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.
		• Individual awards are capped under our ICP, which the Compensation Committee believes mitigates excessive risk taking.
		• The Company has a clawback policy that allows us to recover certain incentive compensation from executive officers and other senior management for the achievement of certain Company financial results that were subsequently subject to a restatement.

Tax Matters

Generally, Internal Revenue Code Section 162(m) limits a tax deduction to public companies for compensation of each “covered employee” to $1 million in any one year. Amendments to Section 162(m) for the Tax Cuts and Jobs Act of 2017 (“Tax Act”) became effective in tax years beginning on or after January 1, 2018. As amended, Section 162(m) no longer allows performance-based compensation to be exempt from the deduction limitation. Further, for tax years beginning on or after January 1, 2018, the deduction limitation applies to compensation of a public company’s CEO, CFO and each of the next three highest compensated executive officers. Beginning in 2017, an employee who becomes a covered employee will remain a covered employee until separation from the Company. The Company structured the 2013 Equity Plan with the intention that certain performance awards made under the plan would qualify for tax deductibility. As a result of changes within the Tax Act, the performance awards are now subject to the deduction limitation along with other compensation.

Employment Agreements for Named Executive Officers

At the time of his selection as CEO, effective November 4, 2019, the Company entered into a five-year employment agreement with Thomas E. McCormick, setting out his annual base salary, plus a performance bonus opportunity. In the event of termination without cause, by death, disability or change of control, certain severance benefits will be paid, including a lump sum payment of 100% of base salary, a pro rata portion of a bonus, up to one year of the employee’s share of the premium for COBRA medical benefits, and accelerated vesting of any RSUs.

At the time of his hire as Chief Operating Officer, effective April 1, 2019, the Company entered into a five-year employment agreement with John F. Moreno, Jr., setting out his annual base salary, issuance of RSUs plus a performance bonus opportunity. In the event of termination without cause, by death, disability or change of control, certain severance benefits will be paid, including a lump sum payment of 100% of base salary, a pro rata portion of a bonus, up to one year of the employee’s share of the premium for COBRA medical benefits, and accelerated vesting of any RSUs.

Salary includes all regular wages paid to the NEO and any amount that was voluntarily deferred by the NEO pursuant to our 401(k) Plan.

The amounts shown in this column represents the discretionary cash awards earned under the Company’s ICP, which is discussed in further detail in the preceding section “Compensation Discussion and Analysis—Compensation Committee Pay Decisions—Incentive Compensation Plan”.

The amounts shown in this column represents the aggregate grant date fair value of the RSUs granted by our Board of Directors computed in accordance with FASB ASC Topic 718, as described in Note 17 to our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2021. The 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. A portion of these awards were granted on March 1, 2021 based on 2020 performance under the Company’s ICP and a portion was a one-time grant on June 29, 2021 to more closely align each NEO’s compensation with our peer companies.

Amounts shown in this column reflect the measurable cash awards earned under the Company’s ICP, which is discussed in further detail in the preceding section “Compensation Discussion and Analysis—Compensation Committee Pay Decisions—Incentive Compensation Plan”.

The threshold, target and maximum amounts in these columns show the range of cash payouts targeted for 2021 that could have been earned based on the achievement of performance goals under the ICP, which is discussed in further detail in “Compensation Discussion and Analysis—Compensation Committee Pay Decisions—Annual Bonuses”.

The RSU awards reported in this column and the “Grant Date Fair Value of Stock Awards” column represent long-term equity incentive awards granted by the Board of Directors under the 2013 Equity Plan. The RSU awards granted on March 1, 2021 vest in three equal installments on each of the first through third anniversaries of March 1, 2021. The RSU awards granted on June 29, 2021 vest 25 percent on June 29, 2023 and 75 percent on June 29, 2024. Excluded from this table are the Dividend Equivalent Units provided for under the RSU Agreement grant. These Divided Equivalent Units are included in the All Other Compensation column of the Summary Compensation Table and the Outstanding Equity Awards at Fiscal Year-End table and therefore do not constitute additional compensation not otherwise reported in this Proxy Statement.

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

Potential Payments Upon Termination

The Company has an employment agreement with Messrs. McCormick, Dodgen, Moreno, and Perisich. 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”, including salary continuation for a twelve-month period.

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, for a change in control, or leaves due to death or disability. The table assumes that the terminating event occurred on December 31, 2021, and the NEO returned an executed release of claims (other than if leaving due to death), on which these termination payments are conditioned.

	Base Salary(1)			Equity(2)			Bonus(3)			Health Care Benefits(4)			Accrued Vacation(5)			Total
Thomas E. McCormick		$	750,000		$	1,456,689		$	1,687,500		$	22,089		$	43,269		$	3,959,547

Represents accelerated vesting, as of December 31, 2021, of RSUs granted to each of the NEOs. The value is based on the closing price of our Common Stock at December 31, 2021.

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

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.

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

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 2021, 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. We are using the same median employee for our 2021 pay ratio as we used for 2020. In this regard, we do not reasonably believe there have been changes in our employee population or compensation that would significantly change our pay ratio. 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 total compensation were calculated consistent with the disclosure requirement of executive compensation under the Summary Compensation Table.

After applying the methodology described above, our median employee compensation using the Summary Compensation Table requirements was $56,828. Our CEO’s compensation as disclosed in the Summary Compensation Table was $3,446,638. Based on this information, the estimate of the ratio of compensation for our CEO to the median employee for 2020 was 61:1. 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.

2013 Equity Incentive Plan

Background. In May 2013, the stockholders approved, and the Company adopted the 2013 Equity Plan.

The principal purpose of our 2013 Equity Plan 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 2013 Equity Plan permits us to grant options or other equity securities to our Directors.

The following table gives information about our Common Stock that may be issued upon the exercise of options, warrants, and rights, or upon settlement of RSUs, all as part of the Company’s 2013 Equity Plan as of December 31, 2021.

Plan category	Number of securities to be issued upon exercise of outstanding options, warrants and rights under equity plan(1) (a)	Weighted-average exercise price per share of outstanding options, warrants and rights (b)	Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in column (a)) (c)

TABLE OF CONTENTS

OTHER MATTERS

This Proxy Statement, being mailed and made available electronically (on our Company website at www.primoriscorp.com) to stockholders on or about March 25, 2022, is being sent to you by the Board of Directors (the “Board”) of Primoris Services Corporation in connection with our 2022 Annual Meeting of Stockholders (the “Annual Meeting”). The Annual Meeting will take place at 9:00 a.m. Central Time, on Wednesday, May 4, 2022, on the 8th floor of our offices at 2300 N. Field Street, Dallas, Texas 75201. To accommodate ongoing public health issues surrounding the COVID-19 virus, we will also provide alternative access for remote participation in the meeting. 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 nine directors to hold office for a one-year term expiring at the Annual Meeting of Stockholders to be held in 2023, or until a successor is elected and qualified, will vote to ratify the appointment of Moss Adams LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022, and will vote to approve the adoption of the Company’s proposed 2022 Employee Stock Purchase Plan. 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 14, 2022 (the “Record Date”), or their duly appointed proxies, may attend the Annual Meeting. You will need to bring personal identification. Gaining admission to the Annual Meeting depends on how your stock ownership is recorded with our transfer agent, Continental Stock Transfer & Trust Company (the “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 proof of ownership, such as a current brokerage account statement or certification from your broker. If your stock is registered directly in your name with our Transfer Agent, all you need is proof of identity; no proof of ownership is needed.

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 53,308,136 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, in person 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.

2022 PROXY STATEMENT

PRIMORIS | 59

TABLE OF CONTENTS

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 in person at the Annual Meeting. We have enclosed a proxy card for you to use.

Voting in person at the Annual Meeting—You may vote in person at the Annual Meeting. If you choose to do so, please bring the enclosed proxy card and proof of identification. 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 by ballot in person 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 at the Annual Meeting in person by following the instructions in the next section below.

Voting in person at the Annual Meeting—You may vote in person at the Annual Meeting by obtaining a signed “legal proxy” from the record holder (e.g., your broker, bank or nominee) prior to the meeting. Please bring your signed “legal proxy” and proof of identification to the meeting.

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 represented in person or by proxy, other than the election of Directors, which is determined by a plurality of shares represented in person or 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 2, the ratification of Moss Adams 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 2, and not on Proposals 1 or 3.

Inspector of elections

Our Executive Vice President, Chief Legal 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.

EMPLOYEE STOCK PURCHASE PLAN

Purpose

The purpose of this 2022 Primoris Services Corporation Employee Stock Purchase Plan (the “Plan”) is to provide employees of the Company and its Designated Subsidiaries with an opportunity to purchase Common Stock through one-time or accumulated Contributions. The Plan is not intended to qualify as an “employee stock purchase plan” as set forth in Section 423 of the Code.

Definitions.

(a)

“Administrator” means the Compensation Committee of the Board (or any successor committee) or such other committee as designated by the Board to administer the Plan under Section 14.

(b)

“Applicable Laws” means the requirements relating to the administration of equity-based awards under U.S. state corporate laws, U.S. federal and state securities laws, the Code, any stock exchange or quotation system on which the Common Stock is listed or quoted and the applicable laws of any foreign country or jurisdiction where options are, or will be, granted under the Plan.

(c)

“Board” means the Board of Directors of the Company.

(d)

“Code” means the Internal Revenue Code of 1986 and the rulings and regulations issued thereunder.

“Compensation” means an Eligible Employee’s base salary or base hourly rate of pay before deduction for any salary deferral contributions made by the Eligible Employee to any tax-qualified or nonqualified deferred compensation plan, but excluding commissions, overtime, incentive compensation, bonuses and other forms of compensation. The Administrator, in its discretion, may, on a uniform and nondiscriminatory basis, establish a different definition of Compensation for an Offering Period.

For purposes of the Plan, the employment relationship shall be treated as continuing intact while the individual is on sick leave or other leave of absence approved by the Company. Where the period of leave exceeds 90 days and the individual’s right to reemployment is not guaranteed either by statute or by contract, the employment relationship shall be deemed to have terminated on the 91st day of such leave. “Eligible Employee” shall not include any person who is a citizen or resident of a foreign jurisdiction if granting them an option under the Plan would violate the law of such jurisdiction, or if compliance with the laws of the jurisdiction would cause the Plan to violate Applicable Law.

TABLE OF CONTENTS

(or, if no sale of Common Stock is reported for such date, on the next preceding date on which any sale shall have been reported); and (ii) in the absence of an established market for the Common Stock, the Fair Market Value thereof shall be determined in good faith by the Administrator.

(p)

“New Exercise Date” means a new Exercise Date if the Administrator shortens any Offering Period then in progress.

(q)

“Offering” means an offer under the Plan of an option that may be exercised during an Offering Period as further described in Section 4.

(u)

“Purchase Price” means an amount equal to 90% of the Fair Market Value of a share of Common Stock on the Enrollment Date or on the Exercise Date, whichever is lower; provided however, that the Purchase Price may be determined for subsequent Offering Periods by the Administrator subject to compliance with Applicable Law or pursuant to Section 18.

(v)

“Subsidiary” means any business association (including a corporation or a partnership, other than the Company) in an unbroken chain of such associations beginning with the Company if each of the associations other than the last association in the unbroken chain owns equity interests (including stock or partnership interests) possessing 50% or more of the total combined voting power of all classes of equity interests in one of the other associations in such chain.

Eligibility.

(a)

Offering Periods. Any Eligible Employee on a given Enrollment Date will be eligible to participate in the Plan if he or she was employed by the Company for at least 30 calendar days immediately preceding the Enrollment Date, subject to the requirements of Section 5, or for such other period preceding the Enrollment Date as determined by the Administrator.

(b)

Non-U.S. Employees. Employees who are citizens or residents of a non-U.S. jurisdiction (without regard to whether they also are citizens or residents of the United States or resident aliens (within the meaning of Section 7701(b)(1)(A) of the Code)) may be excluded from participation in the Plan or an Offering if the participation of such employees is prohibited under the laws of the applicable jurisdiction or if complying with the laws of the applicable jurisdiction would cause the Plan or an Offering to violate Applicable Laws. In addition, as provided in Section 14, the Administrator may establish one or more sub-plans of the Plan to provide benefits

TABLE OF CONTENTS

to employees of Designated Subsidiaries located outside the United States in a manner that complies with local law. Any such sub-plan will be a component of the Plan and will not be a separate plan.

Offering Periods

The Plan will be implemented by specified Offering Periods, with new Offering Periods commencing at such times as determined by the Administrator. The Administrator will have the power to change the duration of Offering Periods (including the commencement dates thereof) without stockholder approval.

Participation

An Eligible Employee may participate in the Plan by (i) submitting to the Company’s Finance department (or its delegate), on or before a date determined by the Administrator prior to an applicable Enrollment Date, a properly completed subscription agreement authorizing or agreeing to remit Contributions in the form provided by the Administrator for such purpose, or (ii) following an electronic or other enrollment procedure determined by the Administrator.

Contributions

(a)

At the time a Participant enrolls in the Plan pursuant to Section 5, such Participant will elect (i) to make Contributions during the Offering Period in an amount specified by such Participant for such Offering Period or (ii) to the extent permitted by the Administrator, have payroll deductions made on each pay day during the Offering Period in an amount equal to at least 1% but not exceeding 15% of the Compensation (or such other percentage of Compensation as determined by the Administrator in its sole discretion), which he or she receives on each pay day during the Offering Period that occurs prior to an Exercise Date. The minimum permissible Contribution by any Participant for an Offering Period shall be $500. The maximum permissible Contribution by any Participant for all Offering Periods during any calendar year shall be $25,000. The Administrator, in its sole discretion, may permit all Participants in a specified Offering to contribute amounts to the Plan through payment by cash, check or other means set forth in the subscription agreement prior to each Exercise Date of each Purchase Period. The Administrator, in its sole discretion, may provide in advance of an applicable Enrollment Date that a Participant’s subscription agreement will remain in effect for the following Offering Periods unless terminated as provided in Section 10.

(b)

Non-payroll Contributions must be made in a manner authorized by the Administrator no later than three calendar days prior to the Exercise Date of such Purchase Period, unless sooner terminated by the Participant as provided in Section 10; provided, however, that if the Participant does not deliver such non-payroll Contributions by the deadline set forth in this Section 6(b), the Participant will be deemed to have withdrawn from participation for such Offering Period under Section 10. To the extent ever permitted by the Administrator, payroll deductions for a Participant will commence on the first pay day following the Enrollment Date and will end on the last pay day prior to the Exercise Date of such Purchase Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in Section 10.

(c)

All Contributions made for a Participant will be credited to his or her notional account under the Plan and payroll deductions, if applicable, will be made in whole percentages only.

(d)

A Participant may discontinue his or her participation in the Plan as provided in Section 10. Participants shall not be permitted to increase or to otherwise decrease their elected Contributions during an Offering Period unless otherwise determined by the Administrator in its sole discretion.

(e)

Notwithstanding the foregoing, a Participant’s Contributions may be reduced or decreased to 0% at any time during a Purchase Period in order to comply with the maximum Contribution limitations set forth in the Plan. The Administrator, in its sole discretion, may provide that such Contributions will recommence at the rate or in the amount originally elected by the Participant effective as of the beginning of the first Purchase Period scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 10.

(f)

Unless determined otherwise by the Administrator, at the time an option under the Plan is exercised, the Company’s or Employer’s federal, state, local or any other tax liability payable to any authority including taxes imposed by jurisdictions outside of the United States, national insurance, social security or other tax withholding obligations, if any, which arise upon the exercise of the option shall be satisfied by having the Company withhold from the Participant a number of shares of Common Stock otherwise deliverable upon such exercise having a Fair Market Value equal to such tax withholding obligation.

Grant of Option

On the Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price)

TABLE OF CONTENTS

up to a number of shares of Common Stock determined by dividing (i) such Eligible Employee’s Contributions made or accumulated prior to such Exercise Date and retained in the Eligible Employee’s notional account as of the Exercise Date by (ii) the applicable Purchase Price; provided, however, that in no event will an Eligible Employee be permitted to purchase during each Purchase Period more than 1,000 shares of Common Stock (subject to any adjustment pursuant to Section 18); provided, further, that such purchase will be subject to the limitations set forth in Sections 3(c) and 13. The Eligible Employee will be deemed to have accepted the grant of such option by electing to participate in the Plan in accordance with the requirements of Section 5. The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of Common Stock that an Eligible Employee may purchase during each Purchase Period of an Offering Period. Exercise of the option will occur as provided in Section 8, unless the Participant has withdrawn pursuant to Section 10. The option will expire on the last day of the Offering Period.

Exercise of Option

(a)

Unless a Participant withdraws from the Plan as provided in Section 10, such Participant’s option for the purchase of shares of Common Stock will be exercised automatically on the Exercise Date, and the maximum number of full shares subject to the option will be purchased for such Participant at the applicable Purchase Price with the accumulated Contributions from his or her notional account. No fractional shares of Common Stock will be purchased; unless determined by the Administrator, any Contributions accumulated in a Participant’s notional account that are not sufficient to purchase a full share will be retained in the Participant’s notional account for the subsequent Purchase Period or Offering Period, subject to earlier withdrawal by the Participant as provided in Section 10. Any other funds left over in a Participant’s notional account after the Exercise Date will be returned to the Participant (without interest thereon, except as otherwise required under local laws, as further set forth in Section 12). During a Participant’s lifetime, a Participant’s option to purchase shares hereunder is exercisable only by him or her.

(b)

If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to be exercised may exceed (i) the number of shares of Common Stock that were available for sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of shares of Common Stock available for sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering Periods then in effect, or (y) provide that the Company will make a pro rata allocation of the shares available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 19. The Company may make a pro rata allocation of the shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s stockholders subsequent to such Enrollment Date.

Delivery

As soon as reasonably practicable after each Exercise Date on which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each Participant of the shares purchased upon exercise of his or her option in a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. The Company may utilize electronic or automated methods of share transfer. Unless otherwise determined by the Administrator, shares of Common Stock must be retained until one year following the Exercise Date on which such shares were purchased. No Participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the Participant as provided in this Section 9.

10.

Withdrawal

A Participant may withdraw all, but not less than all, the Contributions credited to his or her notional account and not yet used to exercise his or her option under the Plan at any time by (a) submitting to the Company’s Finance department (or its delegate) a written notice of withdrawal in the form determined by the Administrator for such purpose, or (b) following an electronic or other withdrawal procedure determined by the Administrator. All of the Participant’s Contributions credited to his or her notional account will be paid to such Participant as soon as reasonably practicable after receipt of notice of withdrawal and such Participant’s option for the Offering Period will be automatically terminated, and no further Contributions for the purchase of shares will be made for such Offering Period. If a Participant withdraws from an Offering Period, Contributions will not resume at the beginning of the succeeding Offering Period, unless the Participant re-enrolls in the Plan in accordance with the provisions of Section 5.

TABLE OF CONTENTS

11.

Termination of Employment

Upon a Participant’s ceasing to be an Eligible Employee, for any reason, he or she will be deemed to have elected to withdraw from the Plan, and the Contributions credited to such Participant’s notional account during the Offering Period but not yet used to purchase shares of Common Stock under the Plan will be returned to such Participant or, in the case of his or her death, to the person or persons entitled thereto under Section 15 (without interest thereon, except as otherwise required under local laws, as further set forth in Section 12), and such Participant’s option will be automatically terminated.

12.

Interest

No interest will accrue on the Contributions of a Participant in the Plan, except as may be required by Applicable Law, as determined by the Company, and if so required by the laws of a particular jurisdiction, shall apply to all Participants in the relevant Offering.

13.

Stock

(a)

Subject to adjustment upon changes in capitalization of the Company as provided in Section 18 hereof, the maximum number of shares of Common Stock that will be made available for sale under the Plan shall be equal to One Million (1,000,000) shares of Common Stock.

(b)

Until the shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), a Participant will only have the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares.

(c)

Shares of Common Stock to be delivered to a Participant under the Plan will be registered in the name of the Participant or in the name of the Participant and his or her spouse.

14.

Administration

The Plan shall be administered by the Administrator. The Board shall fill vacancies on, and from time to time may remove or add members to, the Administrator. Any power of the Administrator may also be exercised by the Board. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to designate separate Offerings under the Plan, to determine eligibility, to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems necessary for the administration of the Plan (including to adopt such procedures and sub-plans as are necessary or appropriate to permit the participation in the Plan by employees who are foreign nationals or employed outside the United States, the terms of which sub-plans may take precedence over other provisions of this Plan, with the exception of Section 13(a), but unless otherwise superseded by the terms of such sub-plan, the provisions of this Plan shall govern the operation of such sub-plan). Unless otherwise determined by the Administrator, the employees eligible to participate in each sub-plan will participate in a separate Offering. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding eligibility to participate, the definition of Compensation, handling of Contributions, making of Contributions to the Plan (including in forms other than payroll deductions), establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates that vary with applicable local requirements. The Administrator also is authorized to determine that the terms of an option granted under the Plan or an Offering to citizens or residents of a non-U.S. jurisdiction will be less favorable than the terms of options granted under the Plan or the same Offering to employees resident solely in the United States. The Administrator hereby delegates to and designates the Chief Financial Officer of the Company (or such other officer with similar authority), and to his or her delegates or designates, the authority to assist the Administrator in the day-to-day administration of the Plan. The Administrator may also delegate some or all of its responsibilities to one or more other persons (which may include Company personnel) and, to the extent there has been any such delegation, any reference in the Plan to the Administrator shall include the delegate of the Administrator. Every finding, decision and determination made by the Administrator will, to the full extent permitted by Applicable Laws, be final and binding upon all parties.

15.

Designation of Beneficiary

(a)

If permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any shares of Common Stock and cash, if any, from the Participant’s notional account under the Plan in the event of such Participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such Participant of such shares and cash. In addition, if permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any cash from the Participant’s notional account under the Plan in the event of such Participant’s death prior to exercise of the option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective.

TABLE OF CONTENTS

(b)

Such designation of beneficiary may be changed by the Participant at any time by notice in a form determined by the Administrator. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company will deliver such shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

(c)

All beneficiary designations will be in such form and manner as the Administrator may designate from time to time. Notwithstanding Sections 15(a) and 15(b), the Company and/or the Administrator may decide not to permit such designations by Participants in non-U.S. jurisdictions.

16.

Transferability

Neither Contributions credited to a Participant’s notional account nor any rights with regard to the exercise of an option or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 hereof.

17.

Use of Funds

The Company may use all Contributions received or held by it under the Plan for any corporate purpose, and the Company will not be obligated to segregate such Contributions except under Offerings in which applicable local law requires that Contributions to the Plan by Participants be segregated from the Company’s general corporate funds and/or deposited with an independent third party for Participants in non-U.S. jurisdictions. Until shares of Common Stock are issued, Participants will only have the rights of an unsecured creditor with respect to such shares.

18.

Adjustments, Dissolution, Liquidation, Merger or Other Corporate Transaction

(a)

Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the corporate structure of the Company affecting the Common Stock occurs, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number and class of Common Stock that may be delivered under the Plan, the Purchase Price per share and the number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and the numerical limits of Sections 7 and 13.

(b)

Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any Offering Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Administrator will notify each Participant in writing or electronically, prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10.

(c)

Merger or Other Corporate Transaction. In the event of a merger, sale or other similar corporate transaction involving the Company, each outstanding option will be assumed or an equivalent option substituted by the successor corporation or a parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option, the Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date on which such Offering Period shall end. The New Exercise Date will occur before the date of the Company’s proposed merger, sale or other similar corporate transaction. The Administrator will notify each Participant in writing or electronically prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10.

19.

Amendment or Termination

(a)

The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and for any reason. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Common Stock on the next Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to Section 18). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ notional accounts that have not been used to purchase shares of Common Stock will be returned to the Participants (without interest thereon, except as otherwise required under local laws, as further set forth in Section 12) as soon as administratively practicable.

(b)

Without stockholder consent and without limiting Section 19(a), the Administrator will be entitled to change the Offering Periods or Purchase Periods, designate separate Offerings, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with Contribution amounts, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable that are consistent with the Plan.

(c)

In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequence including:

(i)

amending the Plan to conform with the safe harbor definition under the Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time;

(ii)

altering the Purchase Price for any Offering Period or Purchase Period including an Offering Period or Purchase Period underway at the time of the change in Purchase Price;

(iii)

(iv)

reducing the maximum percentage of Compensation or other Contributions that a Participant may elect to set aside as Contributions; and

(b)
