    STOCK OWNERSHIP

  58. Compensation Philosophy

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

  59. Processes and Procedures for Determining Executive Compensation

    | Role of Board of Directors The Board provides final approval of Compensation Committee compensation changes for the executive officers. This approval is obtained at an independent Director session without the presence of management Directors. | Role of External Advisor The Compensation Committee engages Meridian as an independent consulting resource as needed to help it with its responsibilities. When requested, information and advice provided by Meridian may include reviews and critique of our executive compensation philosophy and strategies; a competitive analyses of competition program design; and presentations to update market trends. Meridian attends Compensation Committee meetings as requested by the Compensation Committee and conducts private meetings with the Compensation Committee without management representatives at the Committee’s request. | | Role of Executives Our CEO is responsible for reviewing the compensation and performance of all the executive officers, other than himself. He makes recommendations to the Compensation Committee for adjustments in compensation and for any other compensation changes. The Compensation Committee uses the CEO’s recommendations and its evaluation of current individual and business performance and historical individual and business performance to review and approve adjustments in compensation. Our CEO is not present during and does not participate in the discussion of any elements of his compensation with the Compensation Committee. Our CFO, Chief Human Resources Officer, and other Senior Leaders facilitate the sharing of information among the Company, the compensation consultant and the Compensation Committee. In this role, the Leaders communicate with the compensation consultant at the direction of the Compensation Committee. | | | | Role of Benchmarking We believe that it is helpful when making compensation-related decisions to be aware of current practices and pay levels at similarly situated publicly held companies in engineering, construction, and related industries. In July 2025, the Compensation Committee approved a compensation peer group comprised of 15 publicly traded companies (Aecom, Inc., Ameresco, Inc., APi Group Corporation, Arcosa, Inc., Centuri Holdings, Inc., Comfort Systems USA, Inc., Dycom Industries, Inc., EMCOR Group, Inc., Everus Construction Group, Inc., Fluor Corporation, Granite Construction, Inc., IES Holding, Inc., MasTec, Inc., MYR Group, Inc., and Valmont Industries, Inc.). In determining 2025 pay levels for the NEOs, the Compensation Committee reviewed pay data at the 25th, 50th and 75th percentiles for the compensation peer group as well as broader survey data from Aon-Radford, Willis Towers Watson and Mercer. However, the Compensation Committee takes a holistic approach that, in addition to external benchmarking, also considers input from their independent advisor (Meridian), recommendations from our CEO (excluding his own compensation), each executive’s individual performance, the overall Company performance and our compensation strategy. For our NEOs, including the CEO, the Compensation Committee recommends any pay changes to the full Board of Directors for formal approval. |

  61. Annual Incentive Plan

    Annual Incentive Plan The Company’s Annual Incentive Plan (“AIP”) for senior leadership and executives is designed to provide annual awards payable in cash. An eligible NEO that begins employment during the performance year will generally be prorated for their first year based on their date of hire, unless otherwise determined by the CEO and with the approval of the Compensation Committee. Generally, a NEO must be employed by the Company on the date any cash incentive compensation is paid. Otherwise, the NEO forfeits any and all rights to such compensation unless contractual provisions entitle the NEO to a full or pro-rated amount or otherwise as determined by the CEO (other than with respect to himself) and with approval of the Compensation Committee.

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

  65. Adjusted EBITDA Component

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

  66. Adjusted EBITDA Component

    | | AIP Target | AIP Adjusted EBITDA | Achievement | AIP Adjusted EBITDA | | Name | Amount | Component | Percentage | Award Achieved(1) | | Kenneth M. Dodgen | $596,667 | 60% | 200% | $716,000 | | John M. Perisich | 608,489 | 60 | 200 | 730,186 | | Jeremy Kinch | 589,000 | 60 | 200 | 706,800 | | Thomas E. McCormick | 246,329 | 60 | 200 | 295,595 |

  67. New Business Generated Component

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

  68. New Business Generated Component

McCormick | 246,329 | | 15 | | 200 | 73,899 |

  69. Cash Management Component

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

  70. Cash Management Component

  71. Safety Performance Component

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

  72. Safety Performance Component

  75. Long-Term Incentive Plan (“LTIP”)

    Long-Term Incentive Plan (“LTIP”) The LTIP for senior leadership is designed to provide our NEOs with long-term incentive awards payable in equity. Targets are reviewed and set by the Compensation Committee. In connection with the new LTIP design, the 2023 award values approved by the Compensation Committee included both annual and transition components. This approach was intended to be a one-time occurrence and, in 2024 and 2025, LTIP award values were based on the annual component only. As performance periods are completed, we discuss the achievement and any payouts, along with retroactively disclosing the targets for the metrics that do not cause competitive harm, after the relevant portion of the LTIP awards vest. In 2023, 75% of the equity granted was in the form of PSUs and 25% was in the form of RSUs. RSUs vest over three years in increments of 25% after year one, 25% after year two and 50% after year three. PSUs for the 2023 plan year are eligible to vest over three years in increments of 25% after year one, 25% after year two and 50% after year three. Actual vested shares under PSU awards for any vesting year are determined by performance for that year against metrics as outlined below. The Compensation Committee approved, for the 2023 plan year only, the PSU vesting schedule to be ratable with the aim to effectively transition participation from our previous incentive compensation plan. For 2024 and beyond, 65% of the equity granted was in the form of PSUs and 35% was in the form of RSUs. RSUs vest over three years in increments of 25% after year one, 25% after year two and 50% after year three and 100% of the PSUs will cliff vest after year three. The table below represents the number of PSUs and RSUs granted under the LTIP program in 2025:

  76. Long-Term Incentive Plan (“LTIP”)

    | | Total Grant | PSUs Granted | RSUs Granted | | Name | (in units at target) | (in units at target) | (in units) | | Kenneth M. Dodgen | 12,842 | 8,347 | 4,495 | | John M.

Dodgen | 22,364 | 70% | 200% | 31,310 | | John M. Perisich | 25,159 | 70% | 200% | 35,224 | | Jeremy Kinch (2) | 5,182 | 70% | 200% | 7,256 | | Jeremy Kinch (3) | 5,181 | 70% | 200% | 7,254 |

  80. Cumulative Net Income Component

    | 2 | Represents PSUs measured based on total Company performance. |

  81. Cumulative Net Income Component

    | 3 | Represents PSUs measured based on Mr. Kinch’s specific business performance. |

  83. Operating Margin Percentage Component

    | 2 | Represents PSUs measured on total Company performance. |

  84. Operating Margin Percentage Component

    | 3 | Represents PSUs measured on Mr. Kinch’s specific business performance. |

  85. Risk Assessment

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

  86. Equity Grant Practices

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

  95. Summary Compensation Table

    | 3 | The amounts shown in this column represent 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 16 to our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2025. The grant date fair value was based on the market closing price of our stock one day prior to the grant date. This amount reflects our accounting expense to be recognized over the vesting period of the RSUs awarded and does not correspond to the actual value that will be recognized by the NEO. The awards for Messrs. Dodgen and Perisich, were granted on March 1, 2025, 2024, and 2023. The awards for Mr. King and Mr. Vadlamudi were granted on April 1, 2025, and November 10, 2025, respectively. A portion of Mr. Kinch’s awards was granted on March 1, 2025, and a portion was granted on April 1, 2025, in connection with his promotion to Chief Operating Officer. |

  96. Summary Compensation Table

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

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

  131. Pay Ratio Disclosure

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

  132. Pay Ratio Disclosure

    | 2026 PROXY STATEMENT | PRIMORIS | 69 |

  133. Pay Ratio Disclosure

    total compensation were calculated consistent with the disclosure requirement of executive compensation under the Summary Compensation Table. Since we had multiple CEOs during 2025, we chose to combine the total annual compensation for Mr. Vadlamudi, Mr. King and Mr. McCormick to calculate the ratio. After applying the methodology described above, our median employee compensation using the Summary Compensation Table requirements was $62,382. Mr. Vadlamudi’s, Mr. King’s and Mr. McCormick’s combined compensation as disclosed in the Summary Compensation Table was $17,488,087. Based on this information, the estimate of the ratio of compensation for our CEO to the median employee for 2025 was 280:1. The 2025 CEO compensation and pay ratio was temporarily inflated by combining Mr. Vadlamudi’s, Mr. King’s and Mr. McCormick’s 2025 compensation. We do not expect this to repeat in 2026. This ratio is specific to our Company and may not be comparable to any ratio disclosed by another company.
