Unless specifically noted otherwise, as used throughout these consolidated financial statements, “Primoris”, “the Company”, “we”, “our”, “us” or “its” refers to the business, operations and financial results of the Company and its wholly-owned subsidiaries.

Note 2—Basis of Presentation

Interim consolidated financial statements — The interim condensed consolidated financial statements for the three-month and six-month periods ended June 30, 2013 and 2012 have been prepared in accordance with Rule 10-01 of Regulation S-X of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As such, certain disclosures, which would substantially duplicate the disclosures contained in the Company’s latest audited consolidated financial statements, have been omitted.

This Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2013 (the “Second Quarter 2013 Report”) should be read in concert with the Company’s Annual Report on Form 10-K, filed on March 7, 2013, which contains the Company’s audited consolidated financial statements for the year ended December 31, 2012. The interim financial information is unaudited. In the opinion of management, the unaudited information includes all adjustments (consisting of normal recurring adjustments) necessary for the fair presentation of the interim financial information.

Revenue recognition

Fixed-price contracts — Historically, a substantial portion of the Company’s revenue has been generated under fixed-price contracts. For fixed-price contracts, the Company recognizes revenues using the percentage-of-completion method, which may result in uneven and irregular results. Unforeseen events and circumstances can alter the estimate of the costs and potential profit associated with a particular contract. Total estimated costs, and thus contract revenues and income, can be impacted by changes in any of the following: productivity, scheduling, the unit cost of labor, subcontracts, materials and equipment. Additionally, external factors such as weather, client needs, client delays in providing permits and approvals, labor availability, governmental regulation and politics may affect the progress of a project’s completion and thus the timing of revenue recognition. To the extent that original cost estimates are modified, estimated costs to complete increase, delivery schedules are delayed, or progress under a contract is otherwise impeded, cash flow, revenue recognition and profitability from a particular contract may be adversely affected.

7

Table of Contents

In the percentage-of-completion method, estimated revenues and resulting contract income is calculated based on the total costs incurred to date as a percentage of total estimated costs. If an estimate of total contract cost indicates a loss on a contract, the projected loss is recognized in full at the time of the estimate. The loss amount is recognized as an “accrued loss provision” and is included in the accrued expenses and other liabilities amount on the balance sheet. As the percentage-of-completion method is used to calculate revenues, the accrued loss provision is changed so that the gross profit for the contract is zero.

Other contract forms — The Company also uses unit-price, time and material, and cost reimbursable plus fee contracts. For these jobs, revenue is recognized based on contractual terms. For example, time and material contract revenues are recognized based on purchasing and employee time records. Similarly, unit price contracts recognize revenue based on accomplishment of specific units at a specified unit price.

For all of its contracts, the Company includes the provision for estimated losses on uncompleted contracts in accrued expenses. Changes in job performance, job conditions and estimated profitability, including those arising from final contract settlements, may result in revisions to costs and income. These revisions are recognized in the period in which the revisions are identified. Claims are included in the calculation of revenues when realization is probable and amounts can be reliably determined. Revenues in excess of contract costs incurred on claims are recognized when the amounts have been agreed upon with the customer.

The caption “Costs and estimated earnings in excess of billings” represents unbilled receivables which arise when revenues have been recorded but the amount has not been billed under the terms of the contract until a later date. Balances may represent: (a) unbilled amounts arising from the use of the percentage-of-completion method of accounting which may not be billed under the terms of the contract until a later date, (b) incurred costs to be billed under cost reimbursement type contracts, or (c) amounts arising from routine lags in billing. For those contracts in which billings exceed contract revenues recognized to date, excesses are included in the caption “Billings in excess of costs and estimated earnings”.

The Company considers unapproved change orders to be contract variations for which we have customer approval for a change in scope but for which we do not have an agreed upon price change. Costs associated with unapproved change orders are included in the estimated cost to complete the contracts and are treated as project costs as incurred. The Company recognizes revenue equal to costs incurred on unapproved change orders when realization of price approval is probable and the estimated revenue amount is equal to or greater than the costs related to the unapproved change order. Unapproved change orders involve the use of estimates, and it is reasonably possible that revisions to the estimated costs and recoverable amounts may be required in future reporting periods to reflect changes in estimates or final agreements with customers.

The Company considers claims to be amounts Primoris seeks, or will seek, to collect from customers or others for customer-caused changes in contract specifications or design, or other customer-related causes of unanticipated additional contract costs on which there is no agreement with customers on both scope and price changes. Revenue in excess of contract costs from claims is recognized when agreement is reached with customers as to the value of the claims, which in some instances may not occur until after completion of work under the contract. Costs associated with claims are included in the estimated costs to complete the contracts and are treated as project costs when incurred.

In accordance with applicable terms of construction contracts, certain retainage amounts may be withheld by customers until completion and acceptance of the project. Some payments of the retainage may not be received for a significant period after completion of our portion of a project.

Significant revision in contract estimate — As previously discussed, revenue recognition is based on the percentage-of-completion method for firm fixed-price contracts. Under this method, the costs incurred to date as a percentage of total estimated costs are used to calculate the revenue to be recognized. Total estimated costs, and thus contract income, are impacted by many factors.

For projects that were in process in the prior year, but are either completed or continue to be in process during the current year, there can be a difference in revenues and profits related to the prior year, had current year estimates of costs to complete been known in the prior year.

Customer Concentration — The Company operates in multiple industry segments encompassing the construction of commercial, industrial and public works infrastructure assets throughout primarily the United States. Typically, the top ten customers in any one calendar year generate revenues in excess of 50% of total revenues and consist of a different group of customers in each year.

During the three-months and six-months ending June 30, 2013, revenues generated by the top ten customers were $216 million and $443 million, respectively, which represented 48.6% and 51.9%, respectively, of total revenues during the periods. During the three and six month periods ending June 30, 2013, a large gas and electric utility represented 7.6% and 8.0%, respectively, of total revenues and a large pipeline company represented 8.2% and 5.0%, respectively, of total revenues.

Table of Contents

During the three and six months ending June 30, 2012, revenues generated by the top ten customers were $185 million and $364 million, respectively, which represented 54.8% and 57.9%, respectively, of total revenues during the periods. During the three and six month periods ending June 30, 2012, the Louisiana DOT represented 11.6% and 13.3%, respectively, of total revenues and a large gas and electric utility represented 12.1% and 11.9%, respectively, of total revenues.

At June 30, 2013, approximately 6.5% of the Company’s accounts receivable were due from one customer, and that customer provided 6.4% of the Company’s revenues for the six months ended June 30, 2013. At June 30, 2012, approximately 6.8% of the Company’s accounts receivable were due from one customer, and that customer provided 4.1% of the Company’s revenues for the six months ended June 30, 2012.

Multiemployer Plans — The Company participates and contributes to a number of multiemployer benefit plans for its union employees at rates determined by the various collective bargaining agreements. The trustees for each multiemployer plan determines the eligibility and allocations of contributions and benefit amounts, determines the types of benefits and administers the plan. The potential withdrawal obligation may be significant. Any withdrawal liability would be recorded when it is probable that a liability exists and can be reasonably estimated, in accordance with GAAP. In November 2011, the Company withdrew from the Central States Southeast and Southwest Areas Pension Fund multiemployer pension plan. At June 30, 2013, the Company had recorded a withdrawal liability of $7.5 million on its balance sheet. The Company has no plans to withdraw from any other agreements. See Note 19 — Commitments and Contingencies.

Inventory and uninstalled contract materials — Inventory consists of expendable construction materials and small tools that will be used in construction projects and is valued at the lower of cost, using first-in, first-out method, or market. Uninstalled contract materials include certain job specific materials not yet installed which are valued using the specific identification method.

Note 3—Recent Accounting Pronouncements

In January 2013, the FASB issued ASU 2013-01, which clarifies which instruments and transactions are subject to the offsetting disclosure requirements established by ASU 2011-11 , “Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities”. The ASU is effective for the fiscal years beginning on or after January 1, 2013, and interim periods within. Retrospective application is required for any period presented that begins before the entity’s initial application of the new requirements. The adoption of this guidance did not have a material impact on the Company’s financial statements.

In February 2013, the FASB issued ASU 2013-04, Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date (a consensus of the FASB Emerging Issues Task Force) (“ASU 2013-04”). ASU 2013-04 provides guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date. This ASU is an update to FASB ASC Topic 405, “Liabilities”. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company is currently evaluating the impact of this guidance on its financial statements.

Note 4—Fair Value Measurements

ASC Topic 820, “Fair Value Measurements and Disclosures”, defines fair value in GAAP, establishes a framework for measuring fair value and requires certain disclosures about fair value measurements. ASC Topic 820 requires that certain financial assets and financial liabilities be re-measured and reported at fair value each reporting period and that other non-financial assets and liabilities be re-measured and reported at fair value on a non-recurring basis. ASC Topic 820 also establishes three reporting levels for fair value measurements.

In general, fair values determined by Level 1 use quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs use data points that are observable such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs are “unobservable data points” for an asset or liability and include situations where there is little, if any, market activity for the asset or liability.

The following table presents, for each of the fair value hierarchy levels identified under ASC Topic 820, the Company’s financial assets that are required to be measured at fair value at June 30, 2013 and December 31, 2012:

|  |  |  | Fair Value Measurements at Reporting Date |

Short-term investments consist primarily of Certificates of Deposit (“CDs”) purchased through the CDARS (Certificate of Deposit Account Registry Service) process and U.S. Treasury bills with various financial institutions that are backed by the federal government FDIC program.

Other financial instruments of the Company consist of accounts receivable, accounts payable and certain accrued liabilities. These financial instruments generally approximate fair value based on their short-term nature. The carrying value of the Company’s long-term debt approximates fair value based on comparison with current prevailing market rates for loans of similar risks and maturities.

The following table provides a rollforward of the Company’s contingent consideration liability Level 3 fair value measurements during the six months ended June 30, 2013:

Contingent Consideration |  |  |
Balance at December 31, 2012 |  | $ | 23,431 |
Additions: |  |  |
FSSI acquisition on March 11, 2013 |  | 702 |
Change in fair value of contingent consideration |  | 739 |
Reductions: |  |  |
Payment to Rockford sellers |  | (6,900 | )
Payment to Sprint sellers |  | (4,000 | )
Balance at June 30, 2013 |  | $ | 13,972 |

On a quarterly basis, the Company assesses the estimated fair value of the contractual obligation to pay the contingent consideration and any changes in estimated fair value are recorded as other non-operating expense or income in the Company’s statement of operations. Fluctuations in the fair value of contingent consideration are impacted by two unobservable inputs, management’s estimate of the probability (which range from 33% to 95%) of the acquired company meeting the contractual operating performance target and the estimated discount rate (a rate that approximates the Company’s cost of capital). Significant changes in either of those inputs in isolation would result in a significantly different fair value measurement. Generally, a change in the assumption of the probability of meeting the performance target is accompanied by a directionally similar change in the fair value of contingent consideration liability, whereas a change in assumption of the estimated discount rate is accompanied by a directionally opposite change in the fair value of contingent consideration liability.

2013 Acquisition - FSSI

On March 11, 2013, the Company’s subsidiary, PES, purchased the assets of Force Specialty Services Inc. (“FSSI”) which specializes in turn-around work at refineries and chemical plants in the Gulf Coast area. Based in the greater Houston, Texas area, FSSI’s location provides a presence and convenient access to refineries in south Texas, the Houston ship channel and Louisiana.

Table of Contents

The fair value of the consideration for the acquisition was $2,377. Consideration consisted of cash totaling $1,675, of which $1,025 was paid at closing and $650 was paid in the second quarter 2013. The agreement provides for three future potential payments, contingent upon FSSI meeting certain operating performance targets for the remainder of calendar year 2013 and calendar years 2014 and 2015.

The contingent consideration is as follows: (1) $500 in cash for the achievement of pretax income of at least $553 for the remainder of the year ending December 31, 2013; (2) a payment of $500 in cash if pretax income for the year 2014 is at least $2,502; and (3), a payment of $500 in cash if pretax income for the year 2015 is at least $4,227. The estimated fair value of the potential contingent consideration on the acquisition date was $702 and at June 30, 2013 was $721.

The asset purchase agreement also included a provision that PES pay $1,000 for a five-year employment, non-competition and non-solicitation agreement with a key employee. If the employee violates the agreement or terminates his employment prior to the end of the five-year period, he is required to repay the unamortized amount of the $1,000 payment. This agreement has been accounted for as a prepaid asset and is being amortized equally over the five-year period.

At closing the Company received $302 in small tools inventory, $448 in property, plant and equipment, and recorded accounts payable of $1,060.

The acquisition was accounted for using the acquisition method of accounting. The assets acquired and liabilities assumed were measured at their estimated fair value at the acquisition date. The FSSI purchase was included in the Company’s consolidated balance sheet as of June 30, 2013. During the period subsequent to its March 11, 2013 acquisition date, FSSI contributed revenues of $2,990 and $3,473 and gross profit of $183 and $311, for the three and six months ended June 30, 2013, respectively.

During the second quarter 2013, the Company finalized its estimates of the fair value of the contingent consideration, intangible assets and goodwill for the acquisition. The final revision resulted in a change from the estimated values recorded at March 31, 2013, including a decrease in the fair value of the contingent consideration of $136, increases in intangible assets of $800 and a decrease of $936 for goodwill.

The customer relationships were valued at $950 utilizing the “excess earnings method” of the income approach. The estimated discounted cash flows associated with existing customers and projects were based on historical and market participant data. Such discounted cash flows were net of fair market returns on the various tangible and intangible assets that are necessary to realize the potential cash flows.

The fair value of the tradename of $550 was determined based on the “relief from royalty” method. A royalty rate was selected based on consideration of several factors, including external research of third party tradename licensing agreements and their royalty rate levels, and management estimates. The useful life was estimated at five years based on management’s expectation for continuing value of the tradename in the future.

The fair value for the non-compete agreement of $100 was based on a discounted “income approach” model, including estimated financial results with and without the non-compete agreement in place. The agreement was analyzed based on the potential impact of competition that certain individuals could have on the financial results, assuming the agreement was not in place. An estimate of the probability of competition was applied and the results were compared to a similar model assuming the agreement was in place.

Goodwill of $1,087 largely consists of expected benefits from the greater presence and convenient access to south Texas, the Houston ship channel and Louisiana and FSSI’s expertise in turn-around work for refineries and chemical plants. Goodwill also includes the value of the assembled workforce of the FSSI business. Based on the current tax treatment, goodwill and other intangible assets will be deductible for income tax purposes over a fifteen-year period.

2012 Acquisition - Sprint Pipeline Services, L.P.

The March 12, 2012 acquisition of Sprint was accounted for using the acquisition method of accounting. The fair value of the consideration totaled $28,377, which included cash payments of $21,197, Company stock valued at $980 (or 62,052 shares of restricted common stock) and contingent consideration of $6,200.

The contingent consideration was as follows: If income before interest, taxes, depreciation and amortization (“EBITDA”) for 2012, as defined in the purchase agreement, was at least $7,000, we would pay $4,000 in cash to the sellers. The earnout target was achieved in 2012 and was paid in April 2013.

The 2013 earnout target provides for an additional cash payment of $4,000 to the sellers if 2013 EBITDA is at least $7,750. The estimated fair value of the 2013 contingent consideration as of the acquisition date was $2,745 and at June 30, 2013 and December 31, 2012, the estimated fair value of the contingent consideration was $3,205 and $3,020, respectively.

2012 Acquisition - Silva Companies

The May 30, 2012 acquisition of Silva was accounted for using the acquisition method of accounting. The fair value of the consideration was $14,090.

2012 Acquisition - The Saxon Group

The September 28, 2012 acquisition of Saxon was accounted for using the acquisition method of accounting. The fair value of the consideration was $550 in cash, payment of a banknote for $2,429, and contingent consideration valued at $1,950 for total consideration of $4,929.

The contingent consideration included an earnout where the Company would pay $2,500 to the sellers, contingent upon Saxon meeting one of the following two targets: (1) EBITDA for the fifteen month period ending December 31, 2013 of at least $4,000 or; (2) EBITDA for the twenty-one month period ending June 30, 2014 of at least $4,750. The estimated fair value of the contingent consideration on the acquisition date was $1,950. The estimated fair value of the contingent consideration was $2,184 and $2,028 at June 30, 2013 and December 31, 2012, respectively.

2012 Acquisition — Q3 Contracting

The November 17, 2012 acquisition of Q3C was accounted for using the acquisition method of accounting. The fair value of the consideration totaled $55,994, and included a cash payment of $48,116, a contingent earnout with a fair value of $7,448 and payment of $430 in Company common stock. In January 2013, we issued 29,273 shares of unregistered stock.

The contingent consideration included an earnout whereby the Company would pay additional cash to the sellers contingent on Q3C meeting certain operating performance targets. The targets were based on obtaining certain levels of Q3C’s EBITDA as that term is defined in the stock purchase agreement. The targets are as follows:

1. If EBITDA for the period November 18, 2012 through December 31, 2013 is at least $17,700, the Company agreed to pay $3,750 in cash to the sellers, with an additional cash payment of $1,250 if EBITDA exceeds $19,000.

2. If EBITDA for the calendar year 2014 is at least $19,000, the Company agreed to pay $3,750 in cash to the sellers, with an additional cash payment of $1,250 if EBITDA exceeds $22,000.

The fair value of the contingent consideration was estimated at $7,450 as of the purchase date and is included on the Company’s balance sheet as a liability. The fair value is based on management’s evaluation of the probability of Q3C meeting the EBITDA targets for the two periods, discounted at the Company’s estimated average cost of capital. The estimated fair value at June 30, 2013 and December 31, 2012 was $7,862 and $7,490, respectively.

Supplemental Unaudited Pro Forma Information for the three and six months ended June 30, 2013 and 2012

In accordance with ASC Topic 805 we are combining the pro forma information for the FSSI, Sprint, Silva, Saxon and Q3C acquisitions (“the Acquisitions”). The following pro forma information for the three and six months ended June 30, 2013 and 2012 presents the combined results of operations of the Acquisitions combined, as if the Acquisitions had each occurred at the beginning of 2012. The supplemental pro forma information has been adjusted to include:

· the pro forma impact of amortization of intangible assets and depreciation of property, plant and equipment, based on the purchase price allocations;

· the pro forma impact of the expense associated with the amortization of the discount for the fair value of the contingent consideration for potential earnout liabilities that may be achieved in 2013 for the Sprint and FSSI acquisitions and 2013 or 2014 for the Saxon, Q3C and FSSI acquisitions;

· the pro forma tax effect of both the income before income taxes and the pro forma adjustments, calculated using a tax rate of 39.0% for the three and six months ended June 30, 2012 and the applicable periods in 2013; and

· the pro forma increase in weighted average shares outstanding including 62,052 unregistered shares of common stock issued as part of the Sprint acquisition and 29,273 shares of unregistered common stock issued as part of the Q3C acquisition.

Note 11—Credit Arrangements

Revolving Credit Facility

As of June 30, 2013, the Company had a revolving credit facility (the “Credit Agreement”). The Credit Agreement was entered into by and among the Company, The PrivateBank and Trust Company, as administrative agent (the “Administrative Agent”) and co-lead arranger, The Bank of the West, as co-lead arranger and IBERIABANK Corporation (the “Lenders”). The Credit Agreement is a $75 million revolving credit facility whereby the lenders agree to make loans on a revolving basis from time to time and to issue letters of credit for up to the $75 million committed amount. The Credit Agreement also provides for an incremental facility of up to $50 million. The termination date of the Credit Agreement is December 28, 2017.

The principal amount of any loans under the Credit Agreement will bear interest at either: (i) LIBOR plus an applicable margin as specified in the Credit Agreement (based on the Company’s senior debt to EBITDA ratio), or (ii) the Base Rate (which is the greater of (a) the Federal Funds Rate plus 0.5% or (b) the prime rate as announced by the Administrative Agent). Quarterly non-use fees, letter of credit fees and administrative agent fees are payable at rates specified in the Credit Agreement.

The principal amount of any loan drawn under the Credit Agreement may be prepaid in whole or in part, with a minimum prepayment of $5 million, at any time, potentially subject to make-whole provisions.

The Credit Agreement includes customary restrictive covenants for facilities of this type, as discussed below.

Commercial letters of credit amounted to $5,659 at June 30, 2013 and $4,808 at December 31, 2012. Other than the commercial letters of credit, there were no borrowings under this line of credit during the six months ended June 30, 2013, leaving available borrowing capacity at $69,341 at June 30, 2013.

As part of the execution of the Credit Agreement, the previous Loan and Security Agreement dated October 29, 2009, as amended, between the Company and The Private Bank and Trust Company (the “PrivateBank Agreement”), was terminated. There were no borrowings outstanding at the time of the termination and all letter of credit amounts issued and outstanding under the terminated agreement were transferred to the Lenders under the Credit Agreement discussed above.

On December 28, 2012, the Company entered into a $50 million Senior Secured Notes purchase (“Senior Notes”) and a $25 million private shelf agreement (the “Notes Agreement”) by and among the Company and The Prudential Investment Management, Inc. and certain Prudential affiliates (the “Noteholders”).

A total of $50 million in Senior Notes was funded on December 28, 2012. The Senior Notes are due December 28, 2022 and bear interest at an annual rate of 3.65%, paid quarterly in arrears. Annual principal payments of $7.1 million are required beginning December 28, 2016 through December 28, 2021 with a final payment due on December 28, 2022. The principal amount may be prepaid in whole or in part, with a minimum prepayment of $5 million, at any time, subject to make-whole provisions.

The Notes Agreement provides for the issuance of additional notes of up to $25 million, during the first three years of the Notes Agreement with maturity dates no more than 10 years from the date issued, at the market interest rate for notes with equivalent terms and conditions.

All loans made under both the Credit Agreement and the Notes Agreement are secured by our assets, including, among others, our cash, inventory, goods, equipment (excluding equipment subject to permitted liens) and accounts receivable. All of our domestic subsidiaries have issued joint and several guaranties in favor of the Lenders and Noteholders for all amounts under the Credit Agreement and Notes Agreement.

Subordinated Promissory Notes

Subordinated Promissory Note — Rockford. In connection with the 2010 acquisition of Rockford, the Company executed an unsecured promissory note with an initial principal amount of $16,712. As a result of a dispute related to a certain liability at the time of the closing of the transaction, the Company ceased making principal and interest payments in May 2012, when the outstanding balance reached $5,000. In December 2012, the parties came to a resolution and the Company paid $1,500 to cancel the subordinated note.

Subordinated Promissory Note — JCG. In connection with the 2009 acquisition of JCG, the Company executed an unsecured promissory note on December 18, 2009 in favor of the sellers with an initial principal amount of $53,500. The JCG note was paid in full on March 12, 2012.

Note 12 — Noncontrolling Interests

The Company applies the provisions of ASC Topic 810-10-45, which establishes accounting and reporting standards for ownership interests of parties other than the Company in subsidiaries, such as joint ventures and partnerships.

The Company determined that the Blythe joint venture was a variable interest entity (“VIE”) and that the Company was the primary beneficiary as a result of its significant influence over the joint venture operations.

The Blythe joint venture operating activities were included in the Company’s consolidated statements of income as follows:

|  | Three months ended June 30, |  | Six months ended June 30, |
|  | 2013 |  | 2012 |  | 2013 |  | 2012 |
Revenues |  | 15,631 |  | 3,793 |  | 31,903 |  | 5,414 |
Net income attributable to noncontrolling interests |  | 329 |  | 124 |  | 599 |  | 168 |

Since Blythe is a partnership, no tax effect was recognized for the income. There were no distributions to noncontrolling interests and no capital contributions made by noncontrolling interests during the six months ended June 30, 2013 and 2012.

The carrying value of the assets and liabilities associated with the operations of the Blythe joint venture are included in the Company’s consolidated balance sheets as follows:

|  | June 30, 2013 |  | December 31, 2012 |
Cash |  | $ | 4,442 |  | $ | 3,565 |
Accounts receivable |  | 11,464 |  | 8,843 |
Current liabilities |  | 11,680 |  | 9,379 |

The net assets of the joint venture are restricted for use by the project and are not available for general operations of the Company.

As discussed in Note 7— “Equity Method Investments”, the Company owns several non-consolidated investments and has recognized revenues on work performed by the Company for those joint ventures.

Note 15—Stock-Based Compensation

On May 3, 2013, the Board of Directors granted 100,000 Restricted Stock Units (“Units”) under the 2013 Equity Incentive Plan (the “2013 Plan”). The Units vest over a service period of four equal installments in 2014 through 2017, subject to earlier acceleration, termination, cancellation or forfeiture as provided in the underlying award agreement. Each Unit represents the right to receive one share of the Company’s common stock when vested.

The fair value of the Units was based on the closing market price of our common stock on the day prior to the date of the grant, or $21.98 per Unit. Stock compensation expense for the Units is being amortized using the straight-line method over the service vesting period. For the three and six months ended June 30, 2013 the Company recognized $91 in compensation expense. The Company had approximately $2.1 million of unrecognized compensation expense related to the Units at June 30, 2013, which will be recognized over a period of 3.8 years.

Table of Contents

Vested Units accrue “Dividend Equivalents” (as defined in the 2013 Plan) which will be accrued as additional Units. At June 30, 2013, there were no accrued Dividend Equivalent Units.

Note 16—Income Taxes

The effective tax rate on income before taxes and noncontrolling interests for the six months ended June 30, 2013 was 38.22%. The effective tax rate for income attributable to Primoris is 39.0%. The rate differs from the U.S. federal statutory rate of 35% due primarily to state income taxes, the “Domestic Production Activity Deduction” and nondeductible meals and incidental per diems common in the construction industry.

To determine its quarterly provision for income taxes, the Company uses an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rate from quarter to quarter. The Company recognizes interest and penalties related to uncertain tax positions, if any, as an income tax expense.

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the financial reporting basis and tax basis of the Company’s assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of enactment date.

In September 2012, the Internal Revenue Service (“IRS”) concluded an examination of our federal income tax returns for 2008 and 2009, which did not have a material impact on our financial statements. The tax years 2010 through 2011 remain open to examination by the IRS. The statute of limitations of state and foreign jurisdictions vary generally between 3 to 5 years. Accordingly, the tax years 2007 through 2011 generally remain open to examination by the other major taxing jurisdictions in which the Company operates.

Common stock — In March 2013, the Company received $1,455 for 131,989 shares of common stock issued, under a purchase arrangement within the Company’s Long-Term Incentive Plan (“LTI Plan”) for managers and executives. The LTI Plan allows participants to purchase Company common stock at a discount from the market price. The shares purchased in March 2013 were for bonuses earned in 2012 and were calculated at 75% of the average market closing price of December 2012.

As part of the acquisition of Q3C, the Company agreed to issue shares of common stock with a value of $430 based on the average December 2012 closing prices, or $14.69 per share. On January 7, 2013, we issued 29,273 unregistered shares of stock.

Note 19—Commitments and Contingencies

Leases — The Company leases certain property and equipment under non-cancellable operating leases which expire at various dates through 2019. The leases require the Company to pay all taxes, insurance, maintenance and utilities and are classified as operating leases in accordance with ASC Topic 840 “Leases”.

Total lease expense during the three and six months ended June 30, 2013 was $3,700 and $7,545, respectively, compared to $2,517 and $4,759 for the same periods in 2012. The amounts for the three and six months ended June 30, 2013 included lease payments made to related parties of $398 and $797, respectively, and $323 and $648 for the three and six months ended June 30, 2012, respectively.

Letters of credit — At June 30, 2013, the Company had letters of credit outstanding of $9,023 and at December 31, 2012, the Company had letters of credit outstanding of $6,168. The outstanding amounts include the U.S. dollar equivalents for letters of credit issued in Canadian dollars.

Litigation— The Company is subject to claims and legal proceedings arising out of its business. Management believes that the Company has meritorious defenses to such claims. Although management is unable to ascertain the ultimate outcome of such matters, after review and consultation with counsel and taking into consideration relevant insurance coverage and related deductibles, management believes that the outcome of these matters will not have a materially adverse effect on the consolidated financial position of the Company.

Bonding— At June 30, 2013 and December 31, 2012, the Company had bid and completion bonds issued and outstanding totaling approximately $1,388,279 and $1,298,589, respectively.

Withdrawal liability for multiemployer pension plan — In November 2011, Rockford and ARB, along with other members of the Pipe Line Contractors Association (“PLCA”), withdrew from the Central States Southeast and Southwest Areas Pension Fund multiemployer pension plan (the “Plan”). In connection with the withdrawal, the Company has recorded an estimated liability of $7,500 based on information provided by the Plan. The Company withdrew from the Plan in order to mitigate its liability in connection with the Plan, which is significantly underfunded. The Plan has asserted that the PLCA members did not affect a withdrawal in 2011, although the Company believes that a legally effective withdrawal occurred in November 2011 and has recorded the withdrawal liability on that basis. If the Plan were to prevail in its assertion and the withdrawal of the Company were deemed to occur after 2011, the amount of any withdrawal liability could increase.

Prior to its acquisition, Q3C had also withdrawn from the Plan. In November 2012, Q3C estimated a withdrawal liability of $85. Subsequently, in the first quarter of 2013, the Plan asserted that the liability was $119. Without agreeing to the amount, Q3C is making payments toward the liability amount.

Contingent Consideration — Earnouts related to acquisitions are discussed in Note 8 — Business Combinations and Note 13 — Contingent Earnout Liabilities.

Introduction

Primoris Services Corporation (“Primoris”, the “Company”, “we”, “us” or “our”) is a holding company of various subsidiaries, which form one of the largest publicly traded specialty contractor and infrastructure companies in the United States. Serving diverse end-markets, Primoris provides a wide range of construction, fabrication, maintenance, replacement, water and wastewater, and engineering services to major public utilities, petrochemical companies, energy companies, municipalities, state departments of transportation and other customers. We install, replace, repair and rehabilitate natural gas, refined product, water and wastewater pipeline systems, large diameter gas and liquid pipeline facilities, heavy civil projects, earthwork and site development and also construct mechanical facilities and other structures, including power plants, petrochemical facilities, refineries and parking structures. In addition, we provide maintenance services, including inspection, overhaul and emergency repair services, to cogeneration plants, refineries and similar mechanical facilities. One of our subsidiaries provides engineering and design services for fired heaters and furnaces primarily used in refinery applications.

Including our predecessor companies, we have been in business for more than 65 years. We became a publicly traded company in 2008. At that time, our operations were focused primarily on the West Coast through our subsidiaries ARB, Inc. (“ARB”) and ARB Structures, Inc. We also provided product engineering services through a subsidiary, OnQuest, Inc. and its wholly owned subsidiary, OnQuest Canada, ULC (formerly Born Heaters Canada, ULC) to international customers and water and waste water construction services in Florida through Cardinal Contractors, Inc. ARB and ARB Structures are headquartered in Lake Forest, CA, OnQuest is headquartered in San Dimas, CA, OnQuest Canada, ULC is headquartered in Calgary, Canada and Cardinal Contractors is headquartered in Sarasota, FL.

Since July 2008, we have continued to strategically expand both our capabilities and our geographic presence. This expansion has resulted in significant increases in revenues and profitability. The following is a discussion of the major acquisitions.

· On December 18, 2009, we acquired James Construction Group, LLC, a privately-held Florida limited liability company (“JCG”). JCG is one of the largest general contractors based in the Gulf Coast states and is engaged in highway, industrial and environmental construction, primarily in Louisiana, Texas and Florida.

· On November 8, 2010, we acquired privately-held Rockford Corporation (“Rockford). Based in Hillsboro (outside Portland), Oregon, Rockford specializes in construction of large diameter natural gas and liquid pipeline projects and related facilities throughout most of North America.

· In 2012, we made four acquisitions:

· On March 12, 2012, we purchased certain assets of Sprint Pipeline Services, L.P. (“Sprint”), headquartered in Pearland (outside Houston), Texas. Sprint provides a comprehensive range of pipeline construction, maintenance, upgrade, fabrication and specialty services primarily in Texas and the southeastern United States.

· On May 30, 2012, we purchased certain assets of Silva Contracting Company, Inc., Tarmac Materials, LLC and C3 Interest, LLC (collectively, “Silva”). Based outside of Houston, Texas, Silva provides transportation infrastructure maintenance, asphalt paving, and material sales in the Gulf Coast region of the United States. Following this acquisition, Silva was merged with the operations of JCG.

· On September 28, 2012, we purchased certain assets of The Saxon Group, Inc. (“Saxon”). Based in Suwannee, Georgia (outside Atlanta), Saxon is a full service industrial construction enterprise with special expertise in the industrial gas processing and power plant sectors.

· On November 17, 2012, we purchased all of the stock of Q3 Contracting, Inc., a privately-held Minnesota corporation (“Q3C”). The sellers agreed to treat the acquisition as an asset purchase under Section 338(h)(10) of the Internal Revenue Code. Based in Little Canada, Minnesota, north of St. Paul, Minnesota, Q3C specializes in small diameter pipeline and gas distribution construction, restoration and other services, primarily for utilities in the upper Midwest region of the United States.

· In March 2013, the Company’s subsidiary, Primoris Energy Services Inc. (PES) purchased the assets of Force Specialty Services, Inc. (“FSSI”) which specializes in turn-around work at refineries and chemical plants in the Gulf Coast area.

The Company is a party to the Blythe Power Constructors joint venture (“Blythe”) for the installation of a parabolic trough solar field and steam generation system in California.

During the past five years, we have also created legal entities to consolidate or focus our efforts. For example, in 2009 we created Primoris Renewables, Inc. to focus on alternative energy projects, and in 2012, we created PES which is the legal entity that owns Sprint, Saxon and FSSI. Additionally, some of our subsidiaries have increased their focus on certain industries or geographies. For example, during the past year, Cardinal Contractors has opened a facility near Dallas to better serve water and wastewater construction opportunities in Texas.

Historically, we have longstanding relationships with major utility, refining, petrochemical, power and engineering companies. We have completed major underground and industrial projects for a number of large natural gas transmission and petrochemical companies. With our acquisitions of JCG and Q3C we have expanded our ability to provide services to our historical customers in additional geographies. Our diversified customer base includes many of the leading pipeline, power generation and utility companies in the United States. We often provide services under multi-year master service agreements (“MSA”).

In the second quarter of 2013, we closed two of our small subsidiaries, Calidus and All Day Electric Company, Inc. For 2012, their combined revenue was less than 0.3% of total consolidated Primoris revenue and the costs of closure were not material.

End-Markets

We are a diversified specialty construction company, and our strategy is to serve customers in different end markets. Our primary focus is on the following end markets:

· Underground construction. This market consists of two types of projects. The first is the construction of major capital projects primarily underground infrastructure for the oil and gas, telecommunication and water and wastewater industries. The second is installation, repair and maintenance of underground services, typically for utility customers. Our subsidiaries ARB, Rockford and Sprint provide construction services to the major capital projects market while ARB, Q3C and Sprint provide services to utility customers.

Reportable Segments

We present our operations in three reportable segments: West Construction Services (West), East Construction Services (East) and Engineering. Our segment structure has been determined in accordance with ASC 280, Segment Reporting. All of our segments derive their revenues primarily from construction and product engineering in the United States.

Our two Construction Services segments provide the following:

· installation of underground pipeline, cable and conduits for entities in the petroleum, petrochemical and water industries;

· installation and maintenance of industrial facilities for entities in the petroleum, petrochemical and water industries;

· installation of complex commercial and industrial cast-in-place structures; and

· construction of highways and industrial and environmental construction.

East Construction Services

The East Construction Services segment consists of businesses located primarily in the southeastern United States and along the Gulf Coast. Included in this segment are the operations of JCG’s Heavy Civil, Industrial and Infrastructure & Maintenance divisions; Cardinal Contractor’s water and wastewater construction activities; and the services provided by the 2012 and 2013 acquisitions (Sprint; Silva, Saxon and FSSI).

Table of Contents

West Construction Services

The West Construction Services segment consists of businesses located primarily in the western United States. The segment includes the underground and industrial operations of ARB, Inc.; the operations of Rockford (which performs its major capital underground work throughout the United States); the operations of ARB Structures, Alaska Continental Pipeline, Inc., All Day Electric Company, Inc. (100% owned in 2011 and 50% in prior years), the 2012 acquisition of Q3C, Stellaris, LLC, Primoris Renewables, Inc. and Juniper Rock, Inc. The segment also includes the operations of the Blythe Power Constructors joint venture.

Engineering

The Engineering segment includes the results of OnQuest, Inc. and OnQuest Canada, ULC.

Material trends and uncertainties

We generate our revenue from both large and small construction and engineering projects. The award of these contracts is dependent on a number of factors, many of which are not within our control. Business in the construction industry is cyclical. We depend in part on spending by companies in the energy and oil and gas industries, as well as on municipal water and wastewater customers. Over the past several years, each segment has benefited from demand for more efficient and more environmentally friendly energy and power facilities, local highway and bridge needs and from the strength of the oil and gas industry; however, each of these industries and the government agencies periodically are adversely affected by macroeconomic conditions. Economic factors outside of our control affect the amount and size of contracts in any particular period.

We and our customers are operating in a challenging business environment in light of the on-going economic uncertainty, fluctuations in capital markets and potential regulatory changes and uncertainties. We are closely monitoring our customers and the effect that changes in economic and market conditions and regulatory environment may have on them. We have experienced delays in project awards and the start of awarded projects as customers carefully consider their overall environment prior to investing in new infrastructure. However, we believe that most of our customers, some of whom are regulated utilities, remain financially stable and will be able to continue with their business plans in the long-term without substantial constraints.

Within these trends for the economy in general, we believe that there are positive opportunities within our end markets over the next five-year horizon. The development of shale oil and gas has a positive impact on the capital projects in our underground market both in large diameter pipeline projects and the well fields. The increased emphasis on pipeline integrity by utility companies provides growth potential in our utility underground markets. The apparent long-term nature of reduced natural gas prices should lead to increased opportunities for our industrial markets in the Gulf Coast region, and the impact of regulatory rules in California provides an opportunity for continuing upgrades to power plants. At present, the heavy civil market growth is moderate as state funding is restrained and the timing of any federal funding growth is uncertain. Finally, the continuing drought in the western United States may lead to future opportunities in the water and wastewater market.

We believe that we are positioned to take advantage of the opportunities in our end market segments; however, these opportunities may not occur in a linear fashion. As a contractor, we are dependent on the owners for project development, project funding and project timing. Owners’ decisions and market opportunities tend to cause significant fluctuations in revenues, profits and cash flows.

Seasonality and cyclicality

Our results of operations can be subject to quarterly variations. Some of the variation is the result of weather, particularly rain, which can impact our ability to perform construction services. The weather also limits our ability to bid for and perform pipeline integrity testing and routine maintenance for our utility customers’ underground systems since the systems are used for heating. The acquisitions of Sprint and Q3C have added to the seasonality of our business. Q3C’s primary operations are in the Midwest United States, an area usually affected by inclement weather during the first quarter. Similarly, a significant portion of Sprint’s revenues is derived from utility customers. In most years, utility owners obtain bids and award contracts for major maintenance, integrity and replacement work after the heating season, and the work must be completed by the following winter. In addition, demand for new projects can be lower during the early part of the year due to clients’ internal budget cycles. As a result, we usually experience higher revenues and earnings in the third and fourth quarters of the year as compared to the first two quarters.

We are also dependent on large construction projects which tend not to be seasonal, but can fluctuate from year to year based on general economic conditions. Because of the cyclical nature of our business, the financial results for any period may fluctuate from prior periods, and our financial condition and operating results may vary from quarter-to-quarter.

26

Table of Contents

Our volume of business may be adversely affected by declines or delays in new projects in various geographic regions in the United States. Project schedules, in particular in connection with larger, longer-term projects, can also create fluctuations in the services provided, which may adversely affect us in a given period. The financial condition of our customers and their access to capital, variations in the margins of projects performed during any particular period, regional, national and global economic and market conditions, timing of acquisitions, the timing and magnitude of acquisition assimilation costs, interest rate fluctuations and other factors may also materially affect our periodic results. Accordingly, our operating results for any particular period may not be indicative of the results that can be expected for any other period.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and also affect the amounts of revenues and expenses reported for each period. These estimates and assumptions must be made because certain information that is used in the preparation of our financial statements cannot be calculated with a high degree of precision from data available, is dependent on future events, or is not capable of being readily calculated based on generally accepted methodologies. Often, these estimates are particularly difficult to determine, and we must exercise significant judgment. We use estimates in our assessments of revenue recognition under percentage-of-completion accounting, the allowance for doubtful accounts, useful lives of property and equipment, fair value assumptions in analyzing goodwill and long-lived asset impairments, self-insured claims liabilities and deferred income taxes. Actual results could differ significantly from our estimates, and our estimates could change if there were made under different assumptions or conditions.

Our critical accounting policies, as described in our Annual Report on Form 10-K for the year ended December 31, 2012, relate primarily to revenue recognition for fixed price contracts, income taxes, goodwill, long-lived assets, reserves for uninsured risks and litigation and contingencies. There have been no material changes to our critical accounting policies since December 31, 2012.

Results of operations

In the discussion of our results of operations, we provide separate information for the results of the companies that we have acquired since June 2012. Silva, Saxon, Q3C and FSSI are identified as “Acquired Companies.” For the business units that were part of Primoris at the end of June 2012, results of operations are identified as “Comparable Companies.”

Revenues

Revenues for the three months ended June 30, 2013 increased by $107.6 million, or 31.9%, compared to the same period in 2012. The Acquired Companies contributed $55.5 million, or 16.5%, while the Comparable Companies contributed growth of $52.1 million, or 15.4%. Revenues increased at our two construction segments while decreasing in our engineering segment. The primary increases were in underground pipeline revenue for Rockford, which saw a $60.6 million increase primarily in its work in Pennsylvania, and Sprint, which had a $20.7 million increase, while the Blythe joint venture revenue increased by $11.8 million. These increases were partially offset by a decrease of $17.7 million at the JCG Heavy Civil division and of $9.3 million in ARB Underground projects.

Revenues for the six months ended June 30, 2013 increased by $226.0 million, or 35.9%, compared to the same period in 2012. Growth from Comparable Companies contributed $146.1 million, or 23.2%, and the Acquired Companies contributed $79.9 million, or 12.7%. Revenues increased at our two construction segments while decreasing at our engineering segment. The primary increases were in underground pipeline, where Rockford saw a $94.9 million increase, Sprint, which had a revenue increase of $60.5 million (we acquired Sprint during the first quarter of 2012), and the Blythe joint venture, where revenues increased by $26.5 million. These increases were somewhat offset by a reduction in revenues at ARB of $42.8 million.

Gross Profit

Gross profit increased by $15.5 million, or 35.2%, for the three months ended June 30, 2013 compared to the same period in 2012. The Acquired Companies contributed $5.6 million, or 12.9%, while the profit increase from growth at the Comparable Companies was $9.9 million, or 22.5%. The Comparable Companies growth increase included $12.2 million from the West segment primarily attributable to the increase in underground pipeline revenues at Rockford and the approaching completion of a major power project at the ARB Industrial division. Gross profit for the Comparable Companies in the East segment declined by $2.4 million, due primarily to lower volume and lower gross profit margins at the JCG Heavy Civil division.

Gross profit increased by $24.0 million, or 29.4%, for the six months ended June 30, 2013 compared to the same period in 2012. The Acquired Companies contributed $6.2 million, or 7.6%, while the profit increase from growth at the Comparable Companies was $17.8 million, or 21.8%. The Comparable Companies growth increase was $16.9 million from the West segment primarily attributable to the benefit of nearing completion of a major power project and increases in Rockford pipeline revenues. The Comparable Companies of the East and Engineering segments combined gross profit increased by $0.9 million.

Selling, general and administrative expenses

Selling, general and administrative expenses (“SG&A”) increased $8.2 million, or 34.9%, for the three months ended June 30, 2013, compared to the same period in 2012. The increase of SG&A expenses as a result of the Acquired Companies was $4.2 million, or 18.0%, with the balance of the increase of $4.0 million due primarily to a $3.3 million increase in compensation and compensation-related expenses, and increases in other SG&A expenses of $0.7 million.

For the six months ended June 30, 2013, the increase was $16.5 million, or 37.8% compared to the first six months of 2012. The amount of the increase attributable to the Acquired Companies was $7.3 million, or 16.7%. The Comparable Companies increase of $9.2 million, or 21.1%, compared to the same period in 2012, was primarily due to $6.3 million of compensation and compensation-related expenses. These costs increased as a result of increased administrative support costs related to labor-intensive pipeline integrity work and service-related projects, increased incentive compensation expense for a larger number of participants in the management incentive compensation program and cost of living increases. Expenses also increased due to increased transportation expenses of $1.1 million, and consulting, legal and other SG&A expenses of $1.8 million.

SG&A as a percentage of revenue was 7.1% and 7.0% for the three and six months ended June 30, 2013, respectively, compared to 6.9% for both the corresponding periods in 2012. Excluding the impact of the Acquired Companies, SG&A as a percentage of revenue was 7.0% and 6.8% for the three and six months ended June 30, 2013, respectively.

Other income and expense

Non-operating income and expense items for the three and six months ended June 30, 2013 and 2012 were as follows:

|  | Three months ended June 30, |  | Six months ended June 30, |
|  | 2013 |  | 2012 |  | 2013 |  | 2012 |
|  | (Thousands) |  | (Thousands) |
Income (loss) from non-consolidated entities |  | $ | (213 | ) | $ | (47 | ) | $ | 56 |  | $ | 1,054 |
Foreign exchange loss |  | (29 | ) | $ | (6 | ) | $ | (88 | ) | $ | (48 | )
Other expense |  | (377 | ) | (371 | ) | (433 | ) | (579 | )
Interest income |  | 23 |  | 25 |  | 63 |  | 47 |
Interest expense |  | (1,498 | ) | $ | (1,006 | ) | $ | (2,922 | ) | $ | (2,107 | )
Total other income (expense) |  | $ | (2,094 | ) | $ | (1,405 | ) | $ | (3,324 | ) | $ | (1,633 | )

For the three months ended June 30, 2013, the loss from non-consolidated investments was primarily due to a loss recorded at WesPac while for the six months ended June 30, 2013, $0.6 million income from the investment in Alvah offset WesPac losses.

The Company uses the U.S. dollar as its functional currency in Canada since most monetary transactions are made in U.S. dollars. For accounting purposes, transactions made in Canadian dollars are converted to U.S. dollars and we recorded foreign exchange losses for the periods presented.

Other expense represents the increase in the estimated fair value of the contingent earnout liabilities for the acquisitions of Sprint, Saxon, Q3C and FSSI.

For the three and six months ended June 30, 2013, interest expense was $1.5 million and $2.9 million, respectively, compared to $1.0 million and $2.1 million for the same periods in 2012. The increases were due primarily to interest on the $50 million 3.65% Senior Secured Notes, dated December 29, 2012.

Provision for income taxes

Our provision for income taxes increased $2.6 million for the three months ended June 30, 2013 to $10.0 million compared to $7.4 million in the same period in 2012 primarily as a result of higher income before taxes.

Our provision for income taxes increased $2.3 million for the six months ended June 30, 2013 to $16.2 million, compared to $13.9 million for the same period in 2012. The $2.3 million increase results from higher income before taxes and a higher effective tax rate, which contributed to the increase by $2.1 million and $0.2 million, respectively. The tax rate applied to income attributable to Primoris in the six months ended June 30, 2013 was 39.0%, compared to 38.5% for the same period in 2012. The 0.5% increase in the effective tax rate results primarily from the variability of estimated nondeductible per diems.

To determine our quarterly provision for income taxes, we use an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which we operate. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rate from quarter to quarter.

Revenues for the East segment increased by $19.3 million, or 12.4%, for the three months ended June 30, 2013 compared to the same period in the prior year. The acquisitions of Saxon and FSSI added $14.8 million of this increase in revenues. For the quarter, Sprint revenues increased by $20.7 million from increased activity in gas and crude-oil pipeline capital projects in the Eagle Ford area located in south Texas. Cardinal Contractors revenues increased by $4.0 million due to increased work on water treatment facilities in Florida and Texas, and revenues increased by $5.7 million at the JCG Industrial division. These revenue increases were offset by decreases of $17.7 million at the JCG Heavy Civil division and $8.2 million at the JCG Infrastructure and Maintenance division. Compared to the previous year quarter, revenues at Louisiana DOT decreased by $25.8 million which was only partially offset by an increase of $12.2 million from Texas DOT revenues.

Revenues increased by $87.7 million, or 31.6%, for the six months ended June 30, 2013 compared to the same period of the prior year. The acquisitions of Saxon and FSSI contributed $23.7 million, or 8.5%, in revenues. Sprint provided an increase in revenues of $60.5 million, Cardinal Contractors revenues increased by $7.6 million and revenues for the JCG Industrial division increased by $32.9 million. These increases were offset by revenue decreases at the JCG Heavy Civil division of $25.4 million and at the JCG Infrastructure and Maintenance division of $11.7 million due to weather and delays on project startup. Compared to the first six months of 2012, revenues from Louisiana DOT decreased by $46.3 million while revenues from Texas DOT increased by $26.1 million.

Gross profit for the East segment decreased by $2.1 million, or 12.4%, for the three months ended June 30, 2013 compared to the same period in the prior year. This includes a gross profit contribution of $0.2 million from Saxon and FSSI. The gross profit at Cardinal Contractors increased by $0.8 million and the gross profit at the JCG Industrial division increased by $1.0 million. Gross profit from the JCG Heavy Civil division decreased by $4.3 million due primarily from the reduced revenues and the transition from completed projects with higher margins in Louisiana in 2012 and the startup of the Belton area projects.

Gross profit increased by $1.4 million, or 5.0%, for the six months ended June 30, 2013 compared to the same period of the prior year. The acquisitions of Saxon and FSSI contributed $1.1 million in gross profit Sprint contributed $2.2 million in increased gross profit, Cardinal Contractors increased gross profit by $1.5 million and the JCG Industrial division gross profit increased by $3.8 million due to completion of a large industrial facility in south Louisiana. These increases in gross profit were offset by a decrease of $6.8 million at the JCG Heavy Civil division and $0.4 million at the JCG Infrastructure and Maintenance division. The decrease for the JCG Heavy Civil division resulted from the startup of the I-35 projects in Texas and a gross profit reduction for three projects in North Louisiana due to weather conditions and the handling of embankment materials.

Gross profit as a percent of revenues decreased to 8.7% compared to 11.1% in the prior year quarter and decreased to 8.3% for the six months ended June 30, 2013 compared to 10.4% in the same period in the previous year. Gross profit margins at Sprint’s pipeline projects for the first six months of 2013 were at 8.2% due to reduced productivity, adverse weather conditions and project delays. The JCG Heavy Civil division gross profit margins for the first six months of 2013 were at 6.5% due to startup of the I-35 projects in Texas and the impact of the North Louisiana projects.

West Segment

Revenue and gross profit for the West segment for the three and six months ended June 30, 2013 and 2012 were as follows:

Revenue for the West segment increased by $90.9 million, or 54.3%, for the three months ended June 30, 2013, compared to the same period in 2012. The Q3C acquisition added revenues of $40.7 million during the three months ended June 30, 2013. Excluding Q3C, the revenue increase was $50.2 million or 30.0% for the three months ended June 30, 2013, compared to the same period in 2012. Rockford revenues increased by $60.6 million, and parking structure projects adding $2.3 million. The Rockford increase is primarily attributable to pipeline construction projects for major gas utilities in the Pennsylvania shale area. These increases were offset by decreases in the ARB Underground division of $9.3 million and a decrease of $3.3 million for the ARB Industrial division. The reduced revenues at ARB Underground are primarily the result of a $6.9 million reduction in revenues from fewer MSA work authorizations at its largest customer, and the reduction at ARB Industrial reflects the completion of power projects at the end of 2012 and reduced revenues at a large power plant project nearing completion.

Revenue for the West segment increased by $140.6 million, or 43.2%, for the six months ended June 30, 2013, compared to the same period in 2012. Of this increase, $56.2 million was attributable to the acquisition of Q3C. Excluding Q3C, the revenue increase was $84.3 million, or 25.9%, for the six months ended June 30, 2013, compared to the same period in 2012. The increase in revenues was from Rockford’s increase of $94.9 million and parking structure projects adding $6.7 million. These increases were offset by decreases at ARB Underground of $9.4 million and at ARB Industrial of $7.9 million.

Gross profit for the West segment increased by $17.6 million, or 72.6%, during the three months ended June 30, 2013, compared to the same period in 2012. Of this increase, gross profit at Q3C contributed $5.4 million while gross profit excluding Q3C increased by $12.2 million, or 50.2%, for the three months ended June 30, 2013 compared to the same period in 2012. The increases were mainly due to gross profit growth of $5.6 million at Rockford as a result of its increased revenues, increased profit at the ARB Industrial division of $9.7 million as a result of the approaching completion of a major power project and increased gross profit in parking structure projects of $0.6 million For the second quarter of 2013, the gross profit for the ARB Underground business decreased by $3.7 million compared to the same period in 2012, mainly due to the lower revenues.

Gross profit for the West segment increased by $22.0 million, or 45.1%, during the six months ended June 30, 2013, compared to the same period in 2012. Of this increase, gross profit at Q3C contributed $5.1 million for the period. Excluding Q3C, gross profit increased by $16.9 million, or 34.7%, for the six months ended June 30, 2013, compared to the first six months of 2012. The total increase was due to gross profit contributions at ARB Industrial of $11.5 million, Rockford of $3.2 million, ARB Structures of $1.4 million and ARB Underground of $0.8 million. While the ARB Industrial major power plant project is nearing completion, successful completion of the total project could result in a benefit from remaining contingent cost items.

Gross profit as a percent of revenue increased to 16.2% and 15.2% during the three and six months ended June 30, 2013, respectively, from 14.5% and 15.0%, in the same periods of 2012. These increased percentages were due primarily to the impact of the near completion of the ARB Industrial power plant project.

Engineering Segment

Revenue and gross profit for the Engineering segment for the three and six months ended June 30, 2013 and 2012 were as follows:

|  | Three Months Ended June 30, |
|  | 2013 |  | 2012 |
|  | (Thousands) |  | % of Revenue |  | (Thousands) |  | % of Revenue |
Revenue |  | $ | 11,421 |  |  |  | $ | 14,092 |  |  |

Gross profit |  | 4,748 |  | 20.2 | % | 4,127 |  | 16.0 | %

Revenue for the Engineering segment decreased by $2.7 million, or 19.0%, for the three months ended June 30, 2013, and by $2.3 million, or 8.8%, for the six months ended June 30, 2013, compared to the same periods in 2012. This decrease is mainly due to delays in the start date of certain capital projects but which are expected to begin later in 2013.

Table of Contents

Gross profit for the Engineering segment for the three months ended June 30, 2013 increased as a percentage of revenue from 16.7% to 21.0%, compared to the same period in 2012, due to the close-out of smaller projects in the period. For the six months ended June 30, 2013, gross profit increased by $0.6 million, or 15.0%, compared to the same period in 2012.

Geographic area financial information

Revenue by geographic area for the six months ended June 30, 2013 and 2012 was as follows:

|  | Six Months Ended June 30, |
|  | 2013 |  | 2012 |
|  | (Thousands) |  | % of Revenue |  | (Thousands) |  | % of Revenue |
Country: |  |  |  |  |  |  |  |  |
United States |  | $ | 845,461 |  | 98.9 | % | $ | 624,293 |  | 99.3 | %
Non—United States |  | 9,547 |  | 1.1 | % | 4,716 |  | 0.7 | %
Total revenues |  | $ | 855,008 |  | 100.0 | % | $ | 629,009 |  | 100.0 | %

All non-United States revenue has been generated in the Engineering Segment. For the table above, we use revenues generated by OnQuest’s Canadian subsidiary, OnQuest Canada, ULC, to estimate non-United States revenues. Traditionally, much of that work was done in the Far East and Australia.

Backlog

For companies in the construction industry backlog can be an indicator of the future revenue stream. Different companies define and calculate backlog in different manners. For the past few years, we considered backlog as the anticipated revenue from the uncompleted portions of existing contracts for which we had known revenue amounts. Thus, we included in our backlog amount the unearned revenue from our fixed price and fixed unit price contracts. We did not include time-and-equipment, time-and-materials and cost-plus contracts in the calculation of backlog, since their ultimate revenue amount is difficult to determine. We also did not include any anticipated revenue from our master service agreements (“MSA”) until we had been given a specific work order or contract. An MSA provides a framework for future work in that contractual terms and conditions have been agreed on, but there is not a minimum amount to which a customer commits. In some instances, a signed MSA has led to no revenues from the customer.

Using the calculations as we have in the past, the following table shows backlog by operating segment at December 31, 2012 and June 30, 2013 and the changes in backlog for the six months ended June 30, 2013 (in millions):

Segment |  | Backlog at December 31, 2012 |  | Contract Additions to Backlog |  | Revenue Recognized from Backlog |  | Backlog at June 30, 2013 |  | Revenue Recognized from Non-Backlog Projects |  | Total Revenue for 6 months ended June 30, 2013 |
East |  | $ | 970 |  | $ | 342 |  | $ | 313 |  | $ | 999 |  | $ | 53 |  | $ | 366 |
West |  | 361 |  | 368 |  | 368 |  | 361 |  | 98 |  | 466 |
Engineering |  | 15 |  | 26 |  | 19 |  | 22 |  | 4 |  | 23 |
Total |  | $ | 1,346 |  | $ | 736 |  | $ | 700 |  | $ | 1,382 |  | $ | 155 |  | $ | 855 |

At June 30, 2013, our total backlog was $1.38 billion representing an increase of $36 million, or 2.7%, from $1.35 billion at December 31, 2012. We expect that during the next four quarters, we will recognize as revenue approximately 45% of the East backlog at June 30, 2013; approximately 97% of the West backlog and approximately 100% of the Engineering backlog.

With the acquisitions of Sprint and Q3C, we have increased the percentage of revenues derived from MSAs which we historically have not included in our backlog calculations. For the first six months of 2013, Q3C derived approximately 77% of its revenue from MSAs, Sprint derived approximately 26% of its revenue from MSAs and ARB derived approximately 55% of its revenue from MSAs.

The following table shows MSA revenue ($ in millions) for the past six quarters:

Quarter |  | MSA Revenue |
2012 Q1 |  | 73 |
2012 Q2 |  | 88 |
2012 Q3 |  | 111 |
2012 Q4 |  | 139 |
2013 Q1 |  | 98 |
2013 Q2 |  | 123 |

Table of Contents

Based on the historical information and to better reflect the transition to an increased level of MSA contract revenue, we believe that changing our backlog calculation to include an estimated MSA level provides a better indication of our future revenue stream. The following table shows the revised backlog by operating segment at June 30, 2013 (in millions). The estimated MSA revenues for the next four quarters, shown in the table below are net of approximately $50 million for MSA projects already included in the traditional backlog calculation.

Segment: |  | Backlog at June 30, 2013 — As Reported Above |  | Estimated Annual MSA Revenues at June 30, 2013 |  | Revised Backlog at June 30, 2013 |
East |  | $ | 999 |  | $ | 92 |  | $ | 1,091 |
West |  | 361 |  | 329 |  | 690 |
Engineering |  | 22 |  | — |  | 22 |
Total |  | $ | 1,382 |  | $ | 421 |  | $ | 1,803 |

We expect that during the next four quarters, we will recognize as revenue approximately 50% of the East revised backlog at June 30, 2013; approximately 98% of the West revised backlog and approximately 100% of the Engineering revised backlog.

Backlog should not be considered a comprehensive indicator of future revenues. The backlog estimates include amounts from estimated MSA revenues, but our customers are not contractually obligated to purchase an amount of services from us under the MSAs. Any of our contracts, MSA, fixed price or fixed unit price, may be terminated by our customers on relatively short notice. In the event of a project cancellation, we may be reimbursed for certain costs, but typically we have no contractual right to the total revenues reflected in backlog. Projects may remain in backlog for extended periods of time as a result of customer delays, regulatory requirements or project specific issues. Even with the inclusion of estimated MSA amounts, future revenues from projects completed under time-and-equipment, time-and-materials and cost-reimbursable-plus-fee contracts are not included in our estimated backlog amount.

Our estimated backlog amount does not include anticipated contract awards

Liquidity and Capital Resources

Liquidity represents our ability to pay our liabilities when they become due, fund business operations, meet our contractual obligations and execute our business plan. Specifically, we need liquidity for working capital, income taxes, debt service, capital expenditures and earn-out obligations. Our primary sources of liquidity are our cash balances at the beginning of each period and our net cash flow; however, we have availability under our lines of credit and shelf facility to meet additional liquidity needs. In order to maintain sufficient liquidity, we evaluate our working capital requirements on a regular basis. We may elect to raise additional capital by issuing common stock, convertible notes, term debt or increasing our credit facility as necessary to fund our operations or to fund the acquisition of new businesses.

At June 30, 2013, our balance sheet included cash and cash equivalents of $113.8 million. We currently have the following credit facilities:

· a $75 million credit facility that expires on December 28, 2017, under which we can issue letters of credit for up to the full amount of the facility. At June 30, 2013, we have issued letters of credit of $5.7 million on this facility, resulting in $69.3 million in available borrowing capacity. The credit agreement also provides for an incremental facility of up to $50 million.

· the Company entered into $50 million Senior secured Notes purchase, funded on December 28, 2012, and a $25 million shelf agreement credit facility, which could be funded during the first three years of the Note Agreement with a maturity no more than 10 years from the date issued. On July 25, 2013, the Company exercised its option to draw down the remaining $25 million under the shelf agreement credit facility, and;

· a $10 million (Canadian dollars) facility for commercial letters of credit in Canada. The credit facility has an annual renewal and provides for the issuance of commercial letters of credit for a term of up to five years. At June 30, 2013, $3.5 million of letters of credit (Canadian dollars) were outstanding, with $6.5 million available under this credit facility for additional letters of credit.

We believe that with our cash on hand, short-term investments, operating cash flows and availability under our existing credit facilities, that we will be able to support our ongoing working capital needs for the next twelve month period.

The most significant components of the $11.6 million use of cash from operations was the $61.2 million change in assets and liabilities from the December 31, 2012 balance sheet to the June 30, 2013 balance sheet. The change is summarized as follows:

· accounts payable decreased by $50.4 million. As noted in both the 2012 Annual Report and the Form 10-Q for the quarter ended March 31, 2013, increased operating activity at the end of the year had resulted in an unusually high level of accounts payable at the end of 2012. Accounts payable aging at the end of June 2013 reflect more historical aging of accounts payable;

· a $17.0 million decrease in accounts receivable. At June 30, 2013, accounts receivable represented 27.1% of our total assets compared to 28.8% at the end of 2012. We continue to maintain an excellent collection history, and we have certain lien rights that can provide additional security for collections;

· a $28.6 million increase in costs and estimated earnings in excess of billings. This increase is the offset to the decrease in the accounts receivable. The increase was approximately $5.1 million for the ARB Underground division, $4.6 million for Q3C and $1.4 million for Sprint primarily representing a time lag from when revenues were earned until the utility customer can be billed. At Rockford, the increase was approximately $15.8 million for a fixed fee contract with billing allowed at certain milestones.

· a $10.1 million decrease in contingent earn-out liabilities, as a result of payments made in April 2013 for $10.9 million to the former owners of Rockford and Sprint upon achievement of 2012 operating targets;

Table of Contents

· a $7.9 million decrease in customer retention deposits representing both normal retention payments and release of the $5 million escrow associated with the Rockford note;

· and a net increase in liabilities resulting from small increases in accrued expenses and billings in excess of costs and estimated earnings offset by small increases in inventory and other current assets and other long term liabilities.

During the first six months of 2013, we paid $18.0 million for income taxes compared to $11.1 million in the same period of the previous year, as a result of taxes on increased income for the six months ended June 30, 2013, compared to the same period in 2012, which included the additional activities of the acquisitions of Sprint, Saxon, Q3C and FSSI.

Investing activities

During the six months ended June 30, 2013, we purchased property and equipment for $49.3 million in cash, compared to $12.4 million during the same period in 2012. These purchases were principally for construction equipment. For the past few years, it has been our practice to invest in property and equipment on a net basis at a level approximating our combined depreciation and amortization expense levels. In the first six months of 2013, we invested $22.4 million in equipment at Q3C. This investment was made to allow Q3C to expand its operations for both new and ongoing customer opportunities. Excluding the Q3C purchases, our purchases level is not far from our past practice. With the Q3C purchases, we expect that our net purchases for 2013 will be approximately $65 million.

We believe the ownership of equipment is generally preferable to renting equipment on a project by project basis, as ownership helps to ensure the equipment is available for our workloads when needed. In addition, ownership has historically resulted in lower overall equipment costs.

As part of our normal equipment upgrade program, during the six months ended June 30, 2013, we received proceeds from the sale of used equipment of $1.7 million compared to $6.7 million for same period in 2012.

We invest excess cash in short-term investments consisting primarily of CDs purchased through the CDARS (Certificate of Deposit Account Registry Service) process and U.S. Treasury bills with various financial institutions that are backed by the federal government. During the first six months of 2013, our sale of short-term investments and movement to cash was $4.2 million compared to sales and movements to cash of $23.0 million in the same period of 2012.

In March 2013, we used $1.0 million in cash for the acquisition of FSSI.

Financing activities

Financing activities provided $16.5 million of cash during the six months ended June 30, 2013. Significant transactions providing and using cash flows from financing activities included:

· $42.4 million proceeds from the issuance of long term debt for equipment financing.

· $25.8 million in repayment of long-term debt and capital leases.

· $1.45 million in proceeds from the issuance of 131,989 shares purchased by the participants in the Primoris Long-Term Retention Plan.

· Dividends paid of $1.55 million.

Off-balance sheet transactions

The following represent transactions, obligations or relationships that could be considered material off-balance sheet arrangements.

· Letters of credit issued under our lines of credit. At June 30, 2013, we had letters of credit outstanding of $9.0 million, primarily for international projects in our Engineering segment and for providing security to our insurance carriers.

· Equipment operating leases with a balance of $14.9 million at June 30, 2013.

· Employment agreements which provide for compensation and benefits under certain circumstances and which may contain a change of control clause. We may be obligated to make payments under the terms of these agreements.

· In the ordinary course of our business, we may be required by our customers to post surety bid or completion bonds in connection with services that we provide. At June 30, 2013, we had $1.4 billion in outstanding bonds.

· Certain of our subsidiaries are parties to collective bargaining agreements with unions. In most instances, these agreements require that we contribute to multi-employer pension and health and welfare plans. For many plans, the contributions are determined annually and required future contributions cannot be determined since contribution rates depend on the total number of union employees and actuarial calculations based on the demographics of all participants. The Employee Retirement Income Security Act of 1974 (ERISA), as amended by the Multi-Employer Pension Amendments Act of 1980, subject employers to potential liabilities in the event of an employer’s complete or partial withdrawal of an underfunded multi-employer pension plan. The Pension Protection Act of 2006 added new funding rules for plan years after 2007 for multi-employer plans that are classified as “endangered”, “seriously endangered”, or “critical” status. As discussed in footnote 19 of the Financial Statements in Item 1, we have recognized a withdrawal liability for one plan. We currently do not anticipate withdrawal from any other multi-employer pension plans. Withdrawal liabilities or requirements for increased future contributions could negatively impact our results of operations and liquidity.

· Other guarantees that we make from time to time, such as guaranteeing the obligations of our subsidiaries.

Impact of Inflation

The primary inflationary factors affecting our operations are labor and fuel costs. The price of fuel is subject to fluctuations for factors beyond our control, but we closely monitor changes and include the available information in our bidding activities. Some of our longer-term contracts with state departments of transportation include clauses which allow us to recover some of the additional costs incurred due to inflation. To date, we have not had a significant impact from inflationary pressures on our cost of labor; and at this time, we cannot estimate the impact of government fiscal policies on wage rates in future periods. In some of our contracts we are responsible for procurement of materials or equipment. For these contracts, we attempt to reduce the risk of inflation by placing firm price purchase orders, or in some cases, purchasing the materials or equipment at the time of the contract.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

In the ordinary course of business, we are exposed to risks related from financial market conditions. For us, these risks primarily include fluctuations in foreign currency exchange rates, interest rates and commodity prices. From time to time, we may seek to manage these risks through the use of financial derivative instruments such as foreign currency exchange contracts and interest rate swaps. At June 30, 2013, we had no such derivative financial instruments.

We do not execute transactions or use financial derivative instruments for trading or speculative purposes. We enter into transactions with counter parties that are generally financial institutions in a manner to limit significant exposure with any one party.

Due to their generally short maturities, the carrying amounts for cash and cash equivalents, accounts receivable, short-term debt and accounts payable and accrued liabilities shown in the consolidated balance sheets approximate fair value at June 30, 2013 and December 31, 2012. At June 30, 2013 and December 31, 2012, we held short term investments which were primarily in four to six month certificates of deposits (“CDs”) through the CDARS (Certificate of Deposit Account Registry Service) program and U. S. Treasury bills with various financial institutions that are backed by the federal government FDIC program. We expect to hold our investments to maturity.

At June 30, 2013, all of our long-term debt was under fixed interest rates.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

As of June 30, 2013, we carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer (“CEO”) and chief financial officer (“CFO”), of the effectiveness of the design and operation of our “disclosure controls and procedures”, as such term is defined under Exchange Act Rules 13a-15(e) and 15d-15(e).

Based on this evaluation, our CEO and CFO concluded that, at June 30, 2013, the disclosure controls and procedures were effective at the reasonable assurance level to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

In designing and evaluating the disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and in reaching a reasonable level of assurance our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. The Company’s disclosure controls and procedures are designed to provide reasonable assurance of achieving their stated objectives.

Changes in Internal Control Over Financial Reporting

During the fiscal quarter ended June 30, 2013, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II. Other Information

Item 1. Legal Proceedings

From time to time, we are subject to claims and legal proceedings arising out of our business. Our management believes that we have meritorious defenses to such claims. Although we are unable to ascertain the ultimate outcome of such matters, after review and consultation with counsel and taking into consideration relevant insurance coverage and related deductibles, our management believes that the outcome of these matters will not have a materially adverse effect on our financial condition or results of operations.

Item 1A. Risk Factors.

In addition to the other information set forth in this Report, you should carefully consider the factors discussed in the section entitled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2012, which to our knowledge have not materially changed. Those risks, which could materially affect our business, financial condition or future results, are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

As part of the consideration for the acquisition of Q3C, the Company issued 29,273 shares of unregistered common stock in February 2013.

Item 3. Defaults Upon Senior Securities.

None.

Item 4. (Removed and Reserved).

Item 5. Other Information.
