NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Dollars In Thousands, Except Share and Per Share Amounts)

(Unaudited)

Note 1—Nature of Business

Organization and operations — Primoris Services Corporation is a holding company of various construction and product engineering subsidiaries. The Company’s underground and directional drilling operations install, replace and repair natural gas, petroleum, telecommunications and water pipeline systems, including large diameter pipeline systems. The Company’s industrial, civil and engineering operations build and provide maintenance services to industrial facilities including power plants, petrochemical facilities, and other processing plants; construct multi-level parking structures; and engage in the construction of highways, bridges and other environmental construction activities. The Company is incorporated in the State of Delaware, and its corporate headquarters is located at 2100 McKinney Avenue, Suite 1500, Dallas, Texas 75201.

Reportable Operating Segments — The Company segregates its business into three operating segments: the West Construction Services segment (“West segment”), the East Construction Services segment (“East segment”) and the Energy segment (“Energy segment”). See Note 19 — “Reportable Operating Segments”.

The following table lists the Company’s primary operating subsidiaries and their operating segment:

Subsidiary		Operating Segment
ARB, Inc. (“ARB”)		West
ARB Structures, Inc.		West
Q3 Contracting, Inc. (“Q3C”)		West
Rockford Corporation (“Rockford”)		West
Vadnais Trenchless Services, Inc. (“Vadnais”)		West
Cardinal Contractors, Inc.		East
BW Primoris, LLC (“BWP”)		East
James Construction Group, LLC (“JCG”):
JCG Heavy Civil Division		East
JCG Infrastructure and Maintenance Division		East
Primoris Energy Services Corporation (“PES”)		Energy
PES Pipeline Services		Energy
PES Industrial Division (formerly JCG Industrial Division)		Energy
OnQuest, Inc.		Energy
OnQuest, Canada, ULC		Energy
Primoris Aevenia, Inc. (“Aevenia”); acquired February 28, 2015		Energy

The Company owned 50% of the Blythe Power Constructors joint venture (“Blythe”) created for the installation of a parabolic trough solar field and steam generation system in California, and its operations have been included as part of the West Construction Services segment. The project has been completed, the project warranty expired in May 2015 and dissolution of the joint venture was completed in the third quarter 2015.

The Company owns a 50% interest in two separate joint ventures, both formed in 2015 to engineer and construct gas-fired power generation facilities: Carlsbad Power Constructors joint venture (“Carlsbad”) and ARB Inc. & B&M Engineering Co. joint venture (“Wilmington”). Both projects are located in the Southern California area. The Carlsbad project is expected to be completed in 2017 and the Wilmington project in 2018. The joint venture operations are included as part of the West segment. As a result of determining that the Company is the primary beneficiary of the two VIE’s, the results of the Carlsbad and Wilmington joint ventures are consolidated in the Company’s financial statements. Financial information for the joint ventures is presented in Note 11— “Noncontrolling Interests”.

On February 28, 2015, the Company acquired the net assets of Aevenia, Inc. for $22.3 million in cash, and established a new entity, Primoris Aevenia, Inc. (“Aevenia”), which operates as part of the Company’s Energy segment. Headquartered in Moorhead, Minnesota, Aevenia is an energy and electrical construction company. Aevenia specializes in overhead and underground line work, substations, telecom/fiber, and certain other client-specific on-demand call out services. The majority of their work is delivered under unit-price Master Services Agreements (“MSAs”). Aevenia has operations in Minnesota, North Dakota, South Dakota and Iowa. The Company believes there are opportunities for Aevenia to grow sales by performing in-house work for other Primoris subsidiaries and to expand the Company’s offerings to

Table of Contents

new geographies in the Midwest United States. On January 29, 2016, the Company acquired the net assets of Mueller Concrete Construction Company (“Mueller”) for $4.1 million. Mueller will operate as a division of Aevenia. See Note 7 — “Business Combinations”.

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 periods ended March 31, 2016 and 2015 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 Annual Report on Form 10-K, filed on February 29, 2016, which contains the Company’s audited consolidated financial statements for the year ended December 31, 2015, have been omitted.

This First Quarter 2016 Report should be read in concert with the Company’s most recent Annual Report on Form 10-K. The interim financial information is unaudited. In the opinion of management, the interim 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 primarily using the percentage-of-completion method, which may result in uneven and irregular results. In the percentage-of-completion method, estimated contract values, estimated cost at completion and total costs incurred to date are used to calculate revenues earned. 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 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.

The Company considers unapproved change orders to be contract variations for which it has customer approval for a change in scope but for which it does 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 based on an estimated probability of realization from change order approval. 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 it 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. Claims are included in the calculation of revenues when realization is probable and amounts can be reliably determined. Revenue in excess of contract costs from claims is recognized when an 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.

Other contract forms — The Company also uses unit-price, time and material, and cost reimbursable plus fee contracts. For these jobs, revenue is recognized primarily based on contractual terms. For example, time and material contract revenues are generally recognized on an input basis, based on labor hours incurred and on purchases made. Similarly, unit price contracts generally recognize revenue on an output based measurement such as the completion of specific units at a specified unit price.

At any time, if an estimate of total contract cost indicates a loss on a contract, the projected loss is recognized in full at that time. The loss amount is recognized as an “accrued loss provision” and is included in the accrued expenses and other current liabilities amount on the balance sheet. For fixed price contracts, 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 remains zero in future periods. If we anticipate that there will be a loss for unit price or cost reimbursable contracts, the projected loss is recognized in full at that time.

Table of Contents

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.

In all forms of contracts, the Company estimates its collectability of contract amounts at the same time that it estimates project costs. If the Company anticipates that there may be issues associated with the collectability of the full amount calculated as revenues, the Company may reduce the amount recognized as revenue to reflect the uncertainty associated with realization of the eventual cash collection. For example, when a cost reimbursable project exceeds the client’s expected budget amount, the client frequently requests an adjustment to the final amount. Similarly, some utility clients reserve the right to audit costs for significant periods after performance of the work. In these situations, the Company may choose to defer recognition of revenue up to the time that the client pays for the services.

The caption “Costs and estimated earnings in excess of billings” in the Consolidated Balance Sheet represents unbilled receivables which arise when revenues have been recorded but the amount will not be billed until a later date. Balances 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 or project milestone, (b) incurred costs to be billed under cost reimbursement type contracts, (c) amounts arising from routine lags in billing, or (d) the revenue associated with unapproved change orders or claims when realization is probable and amounts can be reliably determined. For those contracts in which billings exceed contract revenues recognized to date, the excess amounts are included in the caption “Billings in excess of costs and estimated earnings”.

In accordance with applicable terms of certain construction contracts, 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. In some jurisdictions, retainage amounts are deposited into an escrow account.

Significant revision in contract estimate — 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 revenue. Total estimated costs, and thus contract revenues and margin, are impacted by many factors, which can cause significant changes in estimates during the life cycle of a project.

For projects that were in process at the end of the prior year or prior quarter there can be a difference in revenues and profits that would have been recognized in the prior year or prior quarter, had current estimates of costs to complete been used at the end of the prior year or prior quarter.

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; however, the group that comprises the top ten customers varies from year to year.

During the three months ended March 31, 2016, revenues generated by the top ten customers were $269 million, which represented 62.6% of total revenues during the period. During that period, TXDOT represented 13.5% of total revenues and a Louisiana petrochemical project represented 13.6% of total revenues.

During the three months ended March 31, 2015, revenues generated by the top ten customers were $236 million, which represented 60.2% of total revenues during the period. During that period, a large midstream pipeline company represented 13.9% of total revenues and TX DOT represented 10.9% of total revenues.

At March 31, 2016, approximately 19.5% of the Company’s accounts receivable were due from one customer, and that customer provided 13.6% of the Company’s revenues for the three months ended March 31, 2016. In addition, of total accounts receivable, approximately 14.9% are currently in dispute resolution. See Note 18 — “Commitments and Contingencies”.

At March 31, 2015, approximately 10.6% of the Company’s accounts receivable were due from one customer, and that customer provided 13.9% of the Company’s revenues for the three months ended March 31, 2015. In addition, approximately 17.2% of total accounts receivable at March 31, 2015 were and continue to be in dispute resolution. See Note 18 — “Commitments and Contingencies”.

Multiemployer plans — Various subsidiaries in the West segment are signatories to collective bargaining agreements. These agreements require that the Company participate in and contribute to a number of multiemployer benefit plans for its union employees at rates determined by the agreements. The trustees for each multiemployer plan determine the eligibility and allocations of contributions and benefit amounts, determine the types of benefits and administer the plan. Federal law requires that if the Company were to withdraw from an agreement, it would incur a withdrawal obligation. The potential withdrawal obligation may be significant. In accordance with Generally Accepted Accounting Principles (“GAAP”), any withdrawal liability would be recorded when it is probable that a liability exists and can be reasonably estimated. In November 2011, the Company withdrew from the Central States Southeast and Southwest Areas Pension Fund

Table of Contents

multiemployer pension plan, as discussed in Note 18 — “Commitments and Contingencies”. The Company has no plans to withdraw from any other agreements.

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 are certain job specific materials not yet installed, primarily for highway construction projects, which are valued using the specific identification method relating the cost incurred to a specific project. In most cases, the Company has been able to invoice a state agency for the materials, but title has not yet passed to the state agency.

Deferred tax classification on the statement of financial position — Deferred tax assets and liabilities are classified as non-current in a statement of financial position, reflecting a recent change adopted by the Company at December 31, 2015. This change eliminates the need to analyze temporary differences to determine if deferred taxes should be reported as current or noncurrent. Past practice did not typically align with the time period in which deferred taxes were expected to be recovered or settled. For this reason, effective December 31, 2015 the Company classified all deferred tax assets and liabilities as a net non-current deferred tax asset.

Note 3—Recent Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”. The new standard is effective for reporting periods beginning after December 15, 2017 and early adoption is not permitted. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. Adoption will require new qualitative and quantitative disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, information about contract balances and performance obligations, and assets recognized from costs incurred to obtain or fulfill a contract. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. The Company is currently evaluating the impact of adopting the ASU and the implementation approach to use.

In August 2014, the FASB issued ASU 2014-15 “Presentation of Financial Statements — Going Concern (Subtopic 205-40)” to address the diversity in practice in determining when there is substantial doubt about an entity’s ability to continue as a going concern and when and how an entity must disclose certain relevant conditions and events. This update requires an entity to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern for a period of one year after the date that the financial statements are issued (or available to be issued). If such conditions or events exist, an entity should disclose that there is substantial doubt about the entity’s ability to continue as a going concern for a period of one year after the date that the financial statements are issued (or available to be issued), along with the principal conditions or events that raise substantial doubt, management’s evaluation of the significance of those conditions or events in relation to the entity’s ability to meet its obligations and management’s plans that are intended to mitigate those conditions or events. The guidance is effective for annual and interim periods ending after December 15, 2016. This guidance will impact the disclosure and presentation of how we report any substantial doubt about our ability to continue as a going concern, if such substantial doubt were to exist. The Company will adopt this guidance effective January 1, 2017.

In February 2015, the FASB issued ASU 2015-02 “Consolidation (Topic 810): Amendment to the Consolidation Analysis” which amends existing consolidation guidance, including amending the guidance related to determining whether an entity is a variable interest entity. The update is effective for interim and annual periods beginning after December 15, 2015. As of January 1, 2016, the Company adopted this authoritative guidance which did not have a material impact on the Company’s consolidated financial statements.

On February 25, 2016, The FASB issued ASU 2016-02 “Leases (Topic 842)”. The ASU will require recognition of operating leases with lease terms of more than twelve months on the balance sheet as both assets for the rights and liabilities for the obligations created by the leases. The ASU will require disclosures that provide qualitative and quantitative information for the lease assets and liabilities recorded in the financial statements. The guidance is effective for fiscal years beginning after December 15, 2018. The Company will establish procedures to adopt the ASU.

In March 2016, the FASB issued ASU 2016-09 “Compensation — Stock Compensation (Topic 718) — Improvements to Employee Share-Based Payment Accounting”. The ASU modifies the accounting for excess tax benefits and tax deficiencies associated with share-based payments by requiring that excess tax benefits or deficiencies be included in the income statement rather than in equity. Additionally, the tax benefits for dividends on share-based payment awards will also be reflected in the income statement. As a result of these modifications, the ASU requires that the tax-related cash flows resulting from share-based payments will be shown on the cash flow statement as operating activities rather than as financing activities. This guidance is effective for annual periods beginning after December 15, 2016, with early adoption permitted. The Company is currently evaluating the potential impact of adoption on the Company’s consolidated financial statements.

Note 4—Fair Value Measurements

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

In general, fair values determined by Level 1 inputs 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 the 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 and liabilities that are required to be measured at fair value at March 31, 2016 and December 31, 2015:

			Fair Value Measurements at Reporting Date
	Amount Recorded on Balance Sheet		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)
Assets as of March 31, 2016:
Cash and cash equivalents	$	98,809	$	98,809	—	—
Liabilities as of March 31, 2016: None

Assets as of December 31, 2015:
Cash and cash equivalents	$	161,122	$	161,122	—	—
Liabilities as of December 31, 2015: None

Other financial instruments of the Company not listed in the table 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.

There were no Level 3 amounts as of March 31, 2016 and December 31, 2015; however, the following table provides changes to the Company’s contingent consideration liability Level 3 fair value measurements during the three months ended:

	Significant Unobservable Inputs (Level 3)
	March 2016		March 2015
Contingent Consideration Liability
Beginning balance, January 1	$	—	$	6,922
Additions to contingent consideration liability:
Change in fair value of contingent consideration liability during year	—		45
Reductions in the contingent consideration liability:
Payments to Q3C sellers for meeting performance targets	—		(5,000		)
Ending balance, March 31	$	—	$	1,967

During each quarter in 2015, the Company assessed the estimated fair value of the contractual obligation to pay the contingent consideration and any changes in estimated fair value were recorded as other non-operating expense or income in the Company’s statement of income for that period. Fluctuations in the fair value of contingent consideration are impacted by two unobservable inputs, management’s estimate of the probability (which has ranged from 33% to 100%) of the acquired company meeting the contractual operating performance target and an 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 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 used of the estimated discount rate is accompanied by a directionally opposite change in the fair value of contingent consideration liability.

Note 7 — Business Combinations

On January 29, 2016, the Company acquired certain assets and liabilities of Mueller Concrete Construction Company (“Mueller”) for $4.1 million. The assets were purchased for their estimated fair value and included $2.0 million of fixed assets, $2.0 million of goodwill and $0.1 million of inventory. Mueller will operate as a division of Aevenia. Because of the short period of time between the acquisition date and this report, the estimated values are preliminary and subject to change.

On February 28, 2015, the Company acquired the net assets of Aevenia, Inc. for $22.3 million in cash, and established a new entity, Primoris Aevenia, Inc. (“Aevenia”), which operates as part of the Company’s Energy segment. The acquisition provides electrical construction expertise for the Company and provides a greater presence and convenient access to the central plains area of the United States.

The purchases were accounted for using the acquisition method of accounting. The assets were purchased for their estimated fair value and included current assets, current liabilities, plant and equipment, intangible assets and goodwill.

Note 10—Credit Arrangements

Long-term debt and credit facilities consist of the following:

Commercial Notes Payable and Mortgage Notes Payable

From time to time, the Company enters into commercial equipment notes payable with various equipment finance companies and banks. Interest rates range from 1.78% to 3.51% per annum and maturity dates range from November 30, 2016 to September 24, 2021. The notes are secured by certain construction equipment of the Company.

The Company also entered into two secured mortgage notes payable to a bank, with interest rates of 4.3% per annum and maturity dates of January 1, 2031. The mortgage notes are secured by two buildings.

Revolving Credit Facility

As of March 31, 2016, the Company had a revolving credit facility, as amended on December 12, 2014 (the “Credit Agreement”) with 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, Branch Banking and Trust Company and UMB Bank, N.A. (the “Lenders”). The Credit Agreement is a $125 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 $125 million committed amount. 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 as that term is defined in the Credit Agreement), 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 outstanding were $15,883 at March 31, 2016 and $12,105 at December 31, 2015. Other than commercial letters of credit, there were no borrowings under this line of credit during the three months ended March 31, 2016, and available borrowing capacity at March 31, 2016 was $109,117.

Senior Secured Notes and Shelf Agreement

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, The Prudential Investment Management, Inc. and certain Prudential affiliates (the “Noteholders”). On June 3, 2015, the Notes Agreement was amended to provide for the issuance of additional notes of up to $75 million over the three year period ending June 3, 2018 (“Additional Senior Notes”).

The Senior Notes amount 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 from December 28, 2016 through

Table of Contents

December 28, 2021 with a final payment due on December 28, 2022. The principal amount may be prepaid, with a minimum prepayment of $5 million, at any time, subject to make-whole provisions.

Seven annual principal payments of $3.6 million are required from November 9, 2019 with a final payment due on November 9, 2025.

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.

Both the Credit Agreement and the Notes Agreement contain various restrictive and financial covenants including among others, minimum tangible net worth, senior debt/EBITDA ratio, debt service coverage requirements and a minimum balance for unencumbered net book value for fixed assets. In addition, the agreements include restrictions on investments, change of control provisions and provisions in the event the Company disposes more than 20% of its total assets.

The Company was in compliance with the covenants for the Credit Agreement and Notes Agreement at March 31, 2016.

Canadian Credit Facility

The Company has a demand credit facility for $8,000 in Canadian dollars with a Canadian bank for purposes of issuing 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. The facility provides for an annual fee of 1% for any issued and outstanding commercial letters of credit. Letters of credit can be denominated in either Canadian or U.S. dollars. At March 31, 2016 and December 31, 2015, letters of credit outstanding totaled $1,917 and $2,179 in Canadian dollars, respectively. At March 31, 2016, the available borrowing capacity was $6,083 in Canadian dollars. The credit facility contains a working capital restrictive covenant for our Canadian subsidiary, OnQuest Canada, ULC. At March 31, 2016, OnQuest Canada, ULC was in compliance with the covenant.

Note 11 — Noncontrolling Interests

The Company is currently involved in several joint ventures, each of which have been determined to be a variable interest entity (“VIE”) and the Company was determined to be the primary beneficiary in each as a result of its significant influence over the joint venture operations.

Each joint venture is a partnership, and consequently, no tax effect was recognized for the income attributable to the noncontrolling interests. The net assets of the joint ventures are restricted for use by the specific project and are not available for general operations of the Company.

The Carlsbad joint venture operating activities began in September 2015 and are included in the Company’s consolidated statements of income as follows for the three months ending:

	March 31, 2016

Revenues	$	3,518
Net income attributable to noncontrolling interests	$	155

The Carlsbad joint venture made no distributions to the partners and the Company made no capital contributions to the Carlsbad joint venture during the three months ending March 31, 2016. The project is expected to be completed in 2017.

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

	March 31, 2016

Revenues	$	1,959
Net income attributable to noncontrolling interests	$	68

The Wilmington joint venture made no distributions to the partners and the Company made no capital contributions to the Wilmington joint venture during the three months ending March 31, 2016. The project is expected to be completed in 2018.

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

	March 31, 2016		December 31, 2015

Cash	$	3,551	$	2,339
Accounts receivable	$	1,752	$	2,003
Current liabilities	$	5,072	$	4,247

Note 12 — Contingent Earnout Liabilities

In March 2015, the Company paid $5,000 to the sellers of Q3C based on achievement of an operating performance target for the 2014 calendar year, as outlined in the purchase agreement.

The June 2014 acquisition of Vadnais Company included an earnout of $900, with $450 payable in September 2015 and $450 payable in September 2016, contingent upon meeting a certain performance targets for each of the two periods. The estimated fair value of the contingent consideration on the acquisition date was $679. In September 2015, the Company determined that the operations of Vadnais did not meet the September 2015 performance targets. As a result, the contingent consideration balance of $396 was credited to non-operating income at September 30, 2015. In December 2015, the Company determined that the September 2016 target was not likely to be achieved, and the remaining balance of $368 was credited to non-operating income.

The purchase of Surber in July 2014 provided a contingent earnout amount of up to $1.4 million that could be earned during the period 2014 through 2016. The estimated fair value for the contingent earnout was $1.0 million on the acquisition date. In the fourth quarter 2015, the Company determined that none of the targets for the Surber operations were likely to be achieved, and the remaining balance of $1,083 was credited to non-operating revenue.

The August 2014 purchase of Ram-Fab provided for a contingent earnout amount of $0.2 million which could be earned based on estimated earnings of a six-month operating project. Because the operating results for the Ram-Fab project were not met during the acquisition measurement period, the contingent earnout liability was reduced in June 2015 and the value of intangible assets of the acquisition was reduced by the same amount.

Note 13—Related Party Transactions

Primoris leases property from the sellers of the Mueller acquisition, which commenced January 29, 2016 on a month to month basis. The property is located in Iowa. During the three months ended March 31, 2016, the Company paid three thousand dollars in lease payments to the sellers.

Note 14—Stock-Based Compensation

In July 2008, the shareholders approved and the Company adopted the Primoris Services Corporation 2008 Long-term Incentive Equity Plan, which was replaced by the Primoris Services Corporation 2013 Long-term Incentive Equity Plan (“Equity Plan”), after approval by the shareholders and adoption by the Company on May 3, 2013.

On May 3, 2013, the Board of Directors granted 100,000 Restricted Stock Units (“Units”) to an executive under the Equity Plan. Commencing annually on May 10, 2014 and ending April 30, 2017, the Units vest in four equal installments subject to continuing employment of the executive. At March 31, 2016, a total of 50,000 Units were vested, with an additional 25,000 vested on April 30, 2016. On March 24, 2014, the Board of Directors granted 48,512 Units to a second executive under the Equity Plan. At March 31, 2016, a total of 24,256 Units were vested. The remaining 24,256 Units will vest on March 23, 2017 subject to continuing employment of the executive. On April 5, 2016, the Board of Directors granted 92,321 Units to a third executive under the Equity Plan. Such Units will vest 25% after 12 months, 25% after 24 months and the final 50% after 36 months, subject to earlier acceleration, termination, cancellation or forfeiture as provided in the underlying RSU Award Agreement. At March 31, 2016, none of such Units were vested. Vesting of the grants is also subject to earlier acceleration, termination, cancellation or forfeiture as provided in the underlying Primoris Restricted Stock Unit agreement (“RSU Award Agreement”). Each Unit represents the right to receive one share of the Company’s common stock when vested.

Under guidance of ASC Topic 718 “Compensation — Stock Compensation”, stock-based compensation cost is measured at the date of grant, based on the calculated fair value of the stock-based award, and is recognized as expense over the employee’s requisite service period (generally the vesting period of the award).

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. Stock compensation expense for the Units is being amortized using the straight-line method over the service period. For both the three months ended March 31, 2016 and 2015, the Company recognized $262 in compensation expense. At March 31, 2016, approximately $1.1 million of unrecognized compensation expense remains for the Units, which will be recognized over the next 13 months through April 30, 2017.

Vested Units accrue “Dividend Equivalents” (as defined in the Equity Plan) which will be accrued as additional Units. At March 31, 2016, a total of 891 Dividend Equivalent Units were accrued.

Note 15—Income Taxes

The effective tax rate on income before taxes and noncontrolling interests for the three months ended March 31, 2016 was 38.3%. The effected tax rate for income attributable to Primoris was 40.5%. 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

Table of Contents

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.

The Company’s federal income tax returns are no longer subject to examination for tax years before 2013. The statutes of limitation of state and foreign jurisdictions vary generally between 3 to 5 years. Accordingly, the tax years 2010 through 2014 generally remain open to examination by the other taxing jurisdictions in which the Company operates.

Note 16—Dividends and Earnings Per Share

The Company has paid or declared cash dividends during 2015 and 2016 as follows:

Declaration Date	Payable Date	Record Date	Type
February 24, 2015	April 15, 2015	March 31, 2015	$	0.040 per share

February 22, 2016	April 15, 2016	March 31, 2016	$	0.055 per share

The payment of future dividends is contingent upon our revenues and earnings, capital requirements and general financial condition of the Company, as well as contractual restrictions and other considerations deemed relevant by the Board of Directors.

Note 17—Stockholders’ Equity

Common stock —The Company issued 85,907 shares of common stock in February 2016 and 96,828 shares of common stock in March 2015 under the Company’s LTR Plan. The shares were purchased by the participants of the LTR Plan with payment made to the Company of $1,439 in February 2016 and $1,621 in March 2015. The Company’s LTR Plan for managers and executives allows participants to use a portion of their annual bonus amount to purchase Company common stock at a discount from the market price. The shares purchased in March 2016 were for bonus amounts earned in 2015 and the number of shares was calculated at 75% of the average market price of December 2015.

Note 18—Commitments and Contingencies

Leases — The Company leases certain property and equipment under non-cancellable operating leases which expire at various dates through 2023. 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 months ended March 31, 2016 and 2015 was $5,319 and $4,144, respectively, including amounts paid to related parties of $368 and $360, respectively.

Letters of credit — At March 31, 2016, the Company had letters of credit outstanding of $17,361 and at December 31, 2015, the Company had letters of credit outstanding of $13,679. The outstanding amounts include the U.S. dollar equivalents for letters of credit issued in Canadian dollars.

Bonding — At March 31, 2016 and December 31, 2015, the Company had bid and completion bonds issued and outstanding totaling approximately $1,528,820 and $1,483,877, respectively.

NTTA Settlement — On February 7, 2012, the Company was sued in an action entitled North Texas Tollway Authority (“NTTA”), Plaintiff v. James Construction Group, LLC, and KBR, Inc., Defendants, v. Reinforced Earth Company, Third-Party Defendant (the “Lawsuit”). The Company participated in court-ordered mediation for 18 months, and on February 25, 2015 the Lawsuit was settled for an expected cost to the Company of $9 million which was the accrued liability balance at December 31, 2014. As part of the settlement, one of the defendants paid us $8 million to remove all of their liability. Additionally, a second defendant agreed to provide up to $5.4 million to pay for the total expected remediation cost of approximately $22.4 million. The Company will use the $17 million to pay for a third-party contractor approved by the NTTA. At March 31, 2016, the remaining accrual balance was $16.5 million. In the event that the total remediation costs exceed the estimated amount, the second defendant would pay 20% of the excess amount and the Company would pay for 80% of the excess amount.

Litigation — At March 31, 2016, the Company is engaged in dispute resolution to enforce collection for two construction projects completed by the Company in 2014. For one project, a cost reimbursable contract, the Company has recorded a receivable of $32.9 million, and for the other project, the Company has a receivable balance due of $17.9 million. At March 31, 2016, the Company has not recorded revenues in excess of cost for these two projects; however, the Company has specific reserves for both projects of approximately $26 million included in “billings in excess of costs and estimated earnings.” At this time, the Company cannot predict the amount that it will collect nor the timing of any collection.

The dispute resolution for the $32.9 million receivable involves contractually required international arbitration for four separate construction projects. As part of the process of filing claims and counter-claims with the arbitration tribunal, the Company determined in the fourth quarter of 2015 that there were no remaining claims from the owner for two of the smaller projects for which the Company had been paid in full. As a result, the Company recorded approximately $2 million in revenues and margin in that quarter. During the three months ended March 31, 2016, the owner sought bankruptcy protection in U.S. bankruptcy court. In addition, the Company has pending litigation against the sureties who provided lien and stop payment release bonds for the total amount owed.

The second project (reflecting the balance due of $17.9 million) involved two small jobs (with separate contracts) that were part of the larger project. A dispute over the termination of these two small jobs was mediated by the owner and Company in April 2016. As a result of the mediation, the Company recorded additional revenue and profit of $0.5 million during the first quarter 2016.

The Company is subject to other claims and legal proceedings arising out of its business. The Company provides for costs related to contingencies when a loss from such claims is probable and the amount is reasonably determinable. In determining whether it is possible to provide an estimate of loss, or range of possible loss, the Company reviews and evaluates its litigation and regulatory matters on a quarterly basis in light of potentially relevant factual and legal developments. If we determine an unfavorable outcome is not probable or reasonably estimable, we do not accrue for a potential litigation loss. Management is unable to ascertain the ultimate outcome of other claims and legal proceedings; however, after review and consultation with counsel and taking into consideration relevant insurance coverage and related deductibles/self-insurance retention, management believes that it has meritorious defense to the claims and believes that the reasonably possible outcome of such claims will not, individually or in the aggregate, have a materially adverse effect on the consolidated results of operations, financial condition or cash flows of the Company.

Withdrawal liability for multiemployer pension plan—In November 2011, members of the Pipe Line Contractors Association “PLCA” including ARB, Rockford and Q3C (prior to the Company’s acquisition in 2012), withdrew from the Central States Southeast and Southwest Areas Pension Fund multiemployer pension plan (“Plan”). These withdrawals were made in order to mitigate additional liability in connection with the significantly underfunded Plan. The Company recorded a withdrawal liability of $7,500, which was increased to $7,585 after the acquisition of Q3C, based on information provided by the Plan. The Plan asserted that the PLCA members did not affect a proper withdrawal in 2011, and in May 2014, the Plan asserted that the total liability for the Company was $11,819. A legal proceeding commenced, and a United States District Court ruled that the withdrawal of the PLCA members in 2011 was not effective. The PLCA appealed this decision,

but as required by the Plan, the Company began making monthly payments, including interest, which totaled $1,834 through December 31, 2015. The payments were expensed as they were made.

On September 2, 2015, the U.S. Court of Appeals for the 7th Circuit reversed the decision of the District Court and ruled that the withdrawal was effective in 2011 as had been asserted by the PLCA. The Plan provided the Company with a revised withdrawal liability amount which was approximately the amount originally accrued. During the first quarter of 2016, the Company received a revised payment schedule reflecting all the prior payments. Based on this schedule, the Company determined that its liability was $6,468 at March 31, 2016. While the Company and other members of the PLCA are engaged in arbitration to further reduce the amount owed, the Company will make payments as required by the Plan-provided payment schedule. The Company has no plans to withdraw from any other agreements.

Contingent Consideration — Earnouts related to acquisitions are discussed in Note 12 — “Contingent Earnout Liabilities”.

Note 19—Reportable Operating Segments

The Company segregates its business into three operating segments: the West Construction Services segment (“West segment”), the East Construction Services segment (“East segment”) and the Energy segment (“Energy segment”).

The West segment includes the underground and industrial operations and construction services performed by ARB, ARB Structures, Inc., Rockford, Q3C, and Vadnais, acquired in June 2014. Most of the entities perform work primarily in California; however, Rockford operates throughout the United States and Q3C operates in Colorado and the upper Midwest United States. The Blythe, Carlsbad and Wilmington joint ventures are also included as part of the segment.

The East segment includes the JCG Heavy Civil division, the JCG Infrastructure and Maintenance division, BW Primoris and the Cardinal Contractors, Inc. construction business, located primarily in the southeastern United States and in the Gulf Coast region of the United States.

The Energy segment includes the operations of the PES pipeline and gas facility construction and maintenance operations and the PES Industrial division, whose operations are located primarily in the southeastern United States and in the Gulf Coast region. The segment also includes the Aevenia, Surber and Ram-Fab operations as well as the OnQuest, Inc. and OnQuest Canada, ULC operations, which provide for the design and installation of LNG facilities and high-performance furnaces and heaters for the oil refining, petrochemical and power generation industries.

Introduction

Primoris is a holding company of various subsidiaries, which form one of the larger publicly traded specialty contractors and infrastructure companies in the United States. Serving diverse end-markets, we provide 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; and heavy civil projects, earthwork and site development. We also construct mechanical facilities and other structures, including power plants, petrochemical facilities, refineries, water and wastewater treatment facilities and parking structures. Finally, we provide specialized process and product engineering services.

We have longstanding customer 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 in the western United States, as well as significant projects for our engineering customers. We enter into a large number of contracts each year and the projects can vary in length — from several weeks, to as long as 48 months for completion on larger projects. Although we have not been dependent upon any one customer in any year, a small number of customers tend to constitute a substantial portion of our total revenues.

We recognize revenues and profitability on our contracts depending on the type of contract. For our fixed price, or lump sum, contracts, we record revenue as the work progresses on a percentage-of-completion basis which means that we recognize revenue based on the percentage of costs incurred to date in proportion to the total estimated costs expected to complete the contract. Fixed price contracts may include retainage provisions under which customers withhold a percentage of the contract price until the project is complete. For our unit price, time and material, and cost-plus contracts, we recognize revenue as units are completed or services are performed.

The Company segregates its business into three operating segments, which include: The West Construction Services segment (“West segment”), the East Construction Services segment (“East segment”) and the Energy segment. The following is a brief description of each of our reportable segments and business activities.

The West segment includes the underground and industrial operations and construction services performed by ARB, Inc. (“ARB”), ARB Structures, Inc., Rockford Corporation (“Rockford”), Q3 Contracting, Inc. (“Q3C”), and Vadnais Trenchless

Table of Contents

Services, Inc. (“Vadnais”). ARB and ARB Structures perform work primarily in California; while, Rockford operates throughout the United States and Q3C operates in Colorado and the upper Midwest United States. The segment also included two joint venture operations. The West segment consists of business headquartered primarily in the western United States.

The East segment includes the James Construction Group (“JCG”) Heavy Civil division, the JCG Infrastructure and Maintenance division, BW Primoris, LLC and Cardinal Contractors, Inc. construction business, located primarily in the southeastern United States and in the Gulf Coast region of the United States and includes heavy civil construction and infrastructure and maintenance operations.

The Energy segment businesses are located primarily in the southeastern United States and in the Gulf Coast region of the United States. The segment includes the operations of the Primoris Energy Services (“PES”) pipeline and gas facility construction and maintenance operations, the PES Industrial division, the Ram-Fab operations and the Primoris Aevenia, Inc. (“Aevenia”) operations. Additionally, the segment includes the OnQuest, Inc. (“OnQuest”) and OnQuest Canada, ULC operations for the design and installation of high-performance furnaces and heaters for the oil refining, petrochemical and power generation industries.

The following table lists the Company’s primary operating subsidiaries and their operating segment:

Subsidiary		Operating Segment
ARB, Inc. (“ARB”)		West
ARB Structures, Inc.		West
Q3 Contracting, Inc. (“Q3C”)		West
Rockford Corporation (“Rockford”)		West

The Company owned 50% of the Blythe Power Constructors joint venture (“Blythe”) created for the installation of a parabolic trough solar field and steam generation system in California, and its operations have been included as part of the West segment. The project has been completed, the project warranty expired in May 2015 and dissolution of the joint venture was completed in the third quarter 2015.

For some end markets we perform the same services in each of our West, East and Energy segments, while for other end markets, such as poured-in-place parking structures, only one of our segments currently serves the market. The following table shows the approximate percentage of revenues over three years derived from our major end-markets, with prior periods conformed to the current year market breakdown:

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 many factors, most of which are not within our control. We depend in part on spending by companies in the energy and oil and gas industries, the gas utility industry, as well as 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 activity level in 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 may affect the amount and size of contracts we are awarded in any particular period.

We closely monitor our customers to assess the effect that changes in economic, market and regulatory conditions may have on them. We have experienced reduced spending by some of our customers over the last several years, which we attribute to negative economic and market conditions, and we anticipate that these negative conditions may continue to affect demand for our services in the near-term. Major fluctuations in market prices of oil, gas and other fuel sources have affected demand for our services. The recent significant reduction in the price of oil, gas and liquid natural gas has created uncertainty with respect to demand for our oil and gas pipeline and roustabout services in the near term, with additional uncertainty resulting over the length of time that prices will remain depressed. We believe that our upstream operations, such as the construction of gathering lines within the oil shale formations will remain at lower levels for an extended period. While there was some improvement in the price of oil in the first quarter of 2016, the increase has not resulted in a significant change in the contracting activities of our customers. We believe that over time, the need for pipeline infrastructure for mid-stream and utility companies will result in a continuing need for our services, but the impact of the low oil prices and the bankruptcy of some smaller oil and gas producers may delay midstream pipeline opportunities. The continuing changes in the regulatory environment also affects the demand for our services, either by increasing our work or delaying projects. For example, the regulatory environment in California may well result in delays for the construction of gas-fired power plants while the regulators continue to search for significant renewable resources, but the renewable resources may also create a demand for our construction services. Finally, we believe that regulated utility customers will continue to invest in our maintenance and replacement services.

Seasonality, cyclicality and variability

Our results of operations are subject to quarterly variations. Some of the variation is the result of weather, particularly rain, ice and snow, which can impact our ability to perform construction services. While the majority of the Company’s work is in the southern half of the United States, these seasonal impacts affect revenues and profitability since gas and other utilities defer routine replacement and repair during their period of peak demand. Any quarter can be affected either negatively or positively by atypical weather patterns in any part of the country. In addition, demand for new projects tends to be lower during the early part of the year due to clients’ internal budget cycles. As a result, the Company usually experiences higher revenues and earnings in the third and fourth quarters of the year as compared to the first two quarters.

The Company is also dependent on large construction projects which tend not to be seasonal, but can fluctuate from year to year based on general economic conditions. Our business may be affected by declines or delays in new projects or by client project schedules. Because of the cyclical nature of our business, the financial results for any period may fluctuate from prior periods, and the Company’s financial condition and operating results may vary from quarter-to-quarter. Results from one quarter may not be indicative of its financial condition or operating results for any other quarter or for an entire year.

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 that 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 they were made under different assumptions or conditions.

Table of Contents

As described in our Annual Report on Form 10-K for the year ended December 31, 2015, our critical accounting policies relate primarily to revenue recognition for fixed and unit 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, 2015.

Results of operations

Revenues, gross profit, operating income and net income for the three months ended March 31, 2016 and 2015 were as follows:

	Three Months Ended March 31,
	2016					2015
	(Thousands)			% of Revenue		(Thousands)			% of Revenue
Revenues	$	430,446		100.0	%	$	392,780		100.0	%

Net income attributable to Primoris	$	2,693		0.6	%	$	1,672		0.4	%

Revenues

Revenues for the three months ended March 31, 2016 increased by $37.7 million, or 9.6% compared to the same period in 2015. Revenues increased in both the East and Energy segments while revenue decreased in the West segment. The East and Energy segments were not as significantly impacted by rainy weather in 2016 compared to the prior period and benefitted from a large construction project in southern Louisiana, in part resulting in increases in revenue compared to the decreases in the prior period with more severe, rainy weather. West segment revenues were impacted primarily by the prior year completion of a large Rockford pipeline project in the Houston area.

From an end-market perspective, our end-market revenues during the first quarter of 2016 compared to the prior year increased by $22.4 million for the industrial end-market, $9.5 million for the underground utility end-market, $20.1 million for the heavy civil end-market and $20.0 million for other markets. Revenues decreased by $20.7 million with underground capital end-market and by $13.6 million with the engineering end-market.

Gross Profit

For the three months ended March 31, 2016, gross profit grew slightly by $1.3 million, with the East and Energy segments increasing by $9.0 million as a result of the increased revenues, offset by a decrease of $7.7 million in the West segment. Gross profit as a percent of revenue decreased to 9.1% for the three months ended March 31, 2016, compared to 9.7% for the same period in 2015, reflecting the impact of changes in the mix of work done for two large utility customers in California.

Selling, general and administrative expenses

Selling, general and administrative expenses (“SG&A”) decreased $1.1 million, or 3.3%, for the three months ended March 31, 2016, compared to the same period in 2015. As a result of the completion of settlement discussions by the PLCA, the pension withdrawal liability was reduced by $0.8 million during the first quarter of 2016. Reductions in administration and payroll related expenses primarily accounted for the remainder of the decreased amount.

SG&A as a percentage of revenue for the three months ended March 31, 2016 decreased to 7.6% compared to 8.6% for the corresponding period in 2015 as a result of the decreases in SG&A expenses for the period.

Other income and expense

Non-operating income and expense items for the three months ended March 31, 2016 and 2015 were as follows:

	Three Months Ended March 31,
	2016			2015
	(Thousands)
Foreign exchange gain	$	359		$	436
Other expense	—			(44		)
Interest income	39			12
Interest expense	(2,268		)	(1,922		)
Total other income (expense)	$	(1,870	)	$	(1,518	)

Table of Contents

For the three months ended March 31, 2016, foreign exchange gains and losses reflect currency exchange fluctuations of the United States dollar compared to the Canadian dollar. Many of our contracts in Calgary, Canada are sold based on United States dollars, but a portion of the work is paid for with Canadian dollars creating a positive currency exchange difference as the value of the Canadian dollar is less than the US dollar.

Interest income is derived from interest earned on excess cash invested primarily in short term U.S. Treasury bills, backed by the federal government and other investments that may not be backed by the federal government.

The increase in interest expense for the three months ended March 31, 2016 is due to a higher debt level for equipment debt and senior secured notes.

Provision for income taxes

Our provision for income taxes increased $0.7 million for the three months ended March 31, 2016 to $1.8 million compared to $1.1 million in the same period in 2015 primarily as a result of higher income before taxes and a higher effective tax rate. The tax rate applied to income attributable to Primoris in the three months ended March 31, 2016 was 40.5%, compared to 38.7% for the same period in 2015. The 1.8% increase in the effective tax rate resulted primarily from the variability of state taxes and the partial non-deductibility of meals and incidental per diem expenses.

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.

Segment results

West Segment

Revenue and gross profit for the West segment for the three months ended March 31, 2016 and 2015 were as follows:

	Three Months Ended March 31,
	2016				2015
	(Thousands)		% of Revenue		(Thousands)		% of Revenue

Revenue	$	165,955			$	186,385
Gross profit	$	13,798	8.3	%	$	21,464	11.5	%

Revenue for the West segment decreased by $20.4 million, or 11.0%, for the three months ended March 31, 2016, compared to the same period in 2015. The decrease was primarily the result of a decrease in volume at Rockford of $46.2 million, the result of the 2015 completion of an 88-mile pipeline project in the Houston, Texas area. The decrease was partially offset by increased revenues of $14.6 million at the ARB Structures division from the construction of several parking structures in southern California; increased revenues of $8.9 million at Q3C as the weather improved earlier in 2016 and increased revenue of $3.5 million at the ARB Underground division, primarily from work for its two largest utility customers.

Gross profit for the West segment decreased by $7.7 million, or 35.7%, during the three months ended March 31, 2016, compared to the same period in 2015. While the improved weather resulted in an increase of $2.6 million at Q3C, Rockford gross margin was reduced by $2.4 million, primarily from completion of the 88-mile pipeline project in the prior year. In addition, gross margin at the ARB Underground division was reduced by $4.4 million, primarily from a change in the mix of work done for its two largest utility customers. As occurs frequently in the first quarter of a year, this mix of work reflects a significant reduction in the higher margin work, such as pipeline integrity services. At the ARB Industrial division gross margin was reduced by $2.5 million, primarily from an increase in costs to complete a southern California power plant project during 2016.

Table of Contents

Gross profit as a percentage of revenue decreased to 8.3% during the three months ended March 31, 2016, from 11.5% in the same period in 2015 primarily as a result of decreased margins at the entities discussed above.

East Segment

Revenue and gross profit for the East segment for the three months ended March 31, 2016 and 2015 were as follows:

	Three Months Ended March 31,
	2016				2015
	(Thousands)		% of Revenue		(Thousands)		% of Revenue

Revenue	$	147,971			$	123,700
Gross profit	$	11,522	7.8	%	$	9,108	7.4	%

East Segment revenue increased by $24.3 million, or 19.6 %, for the three months ended March 31, 2016 compared to the same period in 2015. JCG’s Heavy Civil division revenue increased by $16.3 million as increases of $20.4 million from Texas DOT and municipal projects, $4.1 million from LA DOT projects and $3.2 million from Arkansas DOT projects were partially offset by a decrease of $13.1 million from MS DOT projects. Revenue at the JCG Infrastructure & Maintenance division increased by $3.1 million primarily as a result of an increase at a large petrochemical project in Louisiana. Cardinal Contractors revenue increased $3.8 million primarily from an increase in wastewater facility work in the Texas market.

Gross profit increased by $2.4 million or 26.5% for the three months ended March 31, 2016. The gross profit increase was primarily at JCG’s Infrastructure and Maintenance division, which increased $2.3 million. Some of the increase at both the JCG Heavy Civil division and Cardinal Contractors was for jobs for which loss provisions were recognized in earlier quarters, and as a result, for these jobs no gross margin is recognized in the current period.

Gross profit as a percent of revenues increased to 7.8% during the three months ended March 31, 2016 from 7.4% in the same period ended March 31, 2015 due to increased margins at the JCG Infrastructure and Maintenance division.

Energy Segment

Revenue and gross profit for the Energy segment for the three months ended March 31, 2016 and 2015 were as follows:

	Three Months Ended March 31,
	2016				2015
	(Thousands)		% of Revenue		(Thousands)		% of Revenue

Revenue	$	116,520			$	82,695
Gross profit	$	13,957	12.0	%	$	7,433	9.0	%

Revenue for the Energy segment increased by $33.8 million, or 40.9%, for the three months ended March 31, 2016, compared to the same period in 2015. Revenues for the PES Pipeline division increased by $24.7 million primarily as a result of increased revenues from capital projects. The Industrial division of PES experienced an increase in revenues of $23.6 million as increased work on a petrochemical project in south Louisiana offset decreases from the completion of prior year projects. Revenues decreased at OnQuest by $13.6 million primarily as a result of the completion of an LNG project in the first quarter of 2015.

Gross profit for the Energy segment for the three months ended March 31, 2016 increased by $6.5 million or 87.8%, compared to the same period in 2015. The increase is mainly the result of the increased revenues from PES, offset by reduced gross profit on the decreased revenues at OnQuest.

Gross profit as a percent of revenues increased to 12.0% during the three months March 31, 2016, from 9.0% in the prior period, primarily from the impact of the south Louisiana project.

Geographic area financial information

The majority of the Company’s revenues are derived from customers in the United States with approximately 1% generated from sources outside of the United States.

Backlog

For companies in the construction industry, backlog can be an indicator of future revenue streams. Different companies define and calculate backlog in different manners. For the Company, backlog is defined as a combination of: (1) anticipated revenue from the uncompleted portions of existing contracts for which we have known revenue amounts such as for fixed price and fixed unit price contracts (“Fixed Backlog”), and (2) the estimated revenues on master service agreements (“MSA”) for the next four quarters (“MSA Backlog”). We normally do not include time-and-equipment, time-and-materials and cost reimbursable plus fee contracts in the calculation of backlog, since their ultimate revenue amount is difficult to estimate in advance. We will include these types of contracts in backlog if the customer specifies an anticipated revenue amount.

The two components of backlog, Fixed Backlog and MSA Backlog, are detailed below.

Fixed Backlog

Fixed Backlog by operating segment as of December 31, 2015 and March 31, 2016 and the changes in Fixed Backlog for the three months ended March 31, 2016 (in millions) are as follows:

Segment	Beginning Fixed Backlog at December 31, 2015		Contract Additions to Fixed Backlog		Revenue Recognized from Fixed Backlog		Ending Fixed Backlog at March 31, 2016		Revenue Recognized from Non-Fixed Backlog Projects		Total Revenue for three months ended March 31, 2016

West	$	577.1	$	214.3	$	72.2	$	719.2	$	93.7	$	165.9
East	752.3		111.9		144.0		720.2		4.0		148.0
Energy	187.8		43.3		106.3		124.8		10.2		116.5
Total	$	1,517.2	$	369.5	$	322.5	$	1,564.2	$	107.9	$	430.4

Revenues recognized from non-Fixed Backlog projects shown above are generated by projects completed under time-and-equipment, time-and-materials and cost-reimbursable-plus-fee contracts or are revenue from the sale of construction materials, such as rock or asphalt to outside third parties.

As of March 31, 2016, our total Fixed Backlog was $1.56 billion representing an increase of $47.0 million, or 3.1% compared to the $1.52 billion as of December 31, 2015. We expect that approximately 67% of the total Fixed Backlog at March 31, 2016, will be recognized as revenue over the next four quarters, with approximately $522 million expected for the West segment, $404 million for the East segment and $122 million for the Energy segment.

MSA Backlog

The following table outlines historical MSA revenues for the past five quarters ($ in millions):

		Quarterly MSA Revenues
First Quarter — 2015		90.7
Second Quarter — 2015		134.1
Third Quarter — 2015		175.6
Fourth Quarter — 2015		164.7
First Quarter — 2016		105.2

MSA Backlog includes anticipated MSA revenues for the next twelve months. We estimate MSA revenues based on historical trends, anticipated seasonal impacts and estimates of customer demand based on information from our customers.

The following table shows our estimated MSA Backlog at March 31, 2016 by operating segment (in millions):

Segment:	MSA Backlog at March 31, 2016

West	$	564.6
East	4.0
Energy	61.9
Total	$	630.5

Table of Contents

Total Backlog

The following table shows total backlog (Fixed Backlog plus MSA Backlog), by operating segment as of the quarter-end dates shown below (in millions):

Segment:	March 31, 2015		June 30, 2015		September 30, 2015		December 31, 2015		March 31, 2016

West	$	848.6	$	972.7	$	949.3	$	1,077.3	$	1,283.8
East	962.9		935.7		810.9		756.3		724.2
Energy	331.8		290.6		289.6		254.3		186.7
Total	$	2,143.3	$	2,199.0	$	2,049.8	$	2,087.9	$	2,194.7

Backlog should not be considered a comprehensive indicator of future revenues, as a percentage of our revenues are derived from projects that are not part of a backlog calculation. 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. Future revenues from projects completed under time-and-equipment, time-and-materials and cost-reimbursable-plus-fee contracts may not be included in our estimated backlog amount.

Liquidity and Capital Resources

Cash Needs

Liquidity represents our ability to pay our liabilities when they become due, fund business operations and meet our contractual obligations and execute our business plan. Our primary sources of liquidity are our cash balances at the beginning of each period and our net cash flow. If needed, we have availability under our lines of credit to augment 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.

Our cash and cash equivalents totaled $98.8 million at March 31, 2016 compared to $161.1 million at December 31, 2015. The primary reason for the decrease was to fund the working capital needs of construction projects and other operating needs of the Company. We anticipate that our cash and investments on hand, existing borrowing capacity under our credit facility and our future cash flows from operations will provide sufficient funds to enable us to meet our operating needs, our planned capital expenditures and our ability to grow for at least the next twelve months.

The construction industry is capital intensive, and we expect to continue to make capital expenditures to meet anticipated needs for our services. Historically, we have invested an amount that approximated the sum of depreciation and amortization expenses plus proceeds from equipment sales. During the three months ended March 31, 2016, capital expenditures were approximately $12.3 million while the amount of depreciation, amortization and equipment sales during this period was approximately $20.2 million. Capital expenses are expected to total $55 to $60 million for the 2016 year.

Cash Flows

Cash flows during the three months ended March 31, 2016 and 2015 are summarized as follows:

	Three months Ended March 31,

Operating Activities

The source of our cash flow from operating activities and the use of that cash in our operations for the three months ended March 31, 2016 and 2015 were as follows:

	Three months Ended
	March 31,
	2016			2015			Change
	(Thousands)
*Operating Activities:*
Operating income	$	6,619		$	4,245		$	2,374

Net cash (used by) provided by operating activities	$	(35,608	)	$	2,018		$	(37,626	)

The net change in assets and liabilities during the three months ended March 31, 2016 resulted in a use of cash of $55.0 million, compared to $15.9 million in the prior year, an increase in the usage of cash of $39.0 million. The $39.0 million change in assets and liabilities is outlined below:

· The increased use of cash relating to construction projects, which included the change in accounts receivable, customer retention deposits, costs and estimated earnings in excess of billings and billings in excess of costs and estimated earnings totaled $59.1 million. This increase in the use of cash was primarily due to the increase in revenues of $37.7 million for the three months ended March 31, 2016 compared to the same period in 2015 and a greater activity level at the end of March 2016 compared to December 2015 resulting in a greater level of unbilled revenues at the end of the first quarter.

The primary changes for the use of cash of $59.1 million from December 31, 2015 to March 31, 2016 were as follows:

· Accounts receivable increased by $20.5 million reflecting the higher revenues during the three months ended March 31, 2016 compared to the first quarter of 2015. The primary reason for the increase was the increase in accounts receivable for the large south Louisiana project. The customer was in compliance with the contractual terms at the end of the first quarter. At March 31, 2016 accounts receivable represented 30.6% of our total assets compared to 28.3% at the end of 2015. With the exception of two specific collection issues on two large projects (see the discussion in the “Receivable Collection Actions” below), we continue to maintain an excellent collection history, and we have certain lien rights that can provide additional security for collections;

· Costs and estimated earnings in excess of billings increased by $24.2 million. The increases are primarily associated with the time lag from when revenues were earned until the customer can be billed, which are the result of either contractual terms or the billing lag at the end of each month. The increase during the quarter was approximately $9.2 million for ARB, $7.2 million for PES, $5.4 million for Rockford and $2.4 million for the other operations; and

· Billings in excess of costs and estimated earnings decreased by $14.2 million reflecting the completion of work paid for in advance.

· Primarily as a result of increased revenues, accounts payable increased by $12.0 million in the first quarter of 2016, compared to a decrease in accounts payable of $8.5 million in the first quarter of 2015. This resulted in a decrease of $20.5 million of cash usage for the first quarter of 2016 compared to the same quarter in 2015.

· At March 31, 2016 there were no earn-out liabilities, which was a decrease of $5.0 million compared to the liability at March 31, 2015.

· Uninstalled inventory decreased by $0.5 million in the first quarter of 2016 compared to an increase of $2.5 million in the first quarter of 2015. This resulted in a decrease of $3.0 million of cash usage for the first quarter of 2016 compared to the same quarter in 2015.

· Accrued expenses and other current liabilities decreased by $3.5 million in the first quarter of 2016, compared to a decrease of $6.4 million in the first quarter of 2015. This resulted in an increase of $2.9 million of cash for the first quarter of 2016 compared to the same quarter in 2015.

Investing activities

During the three months ended March 31, 2016, we purchased property and equipment for $12.3 million in cash compared to $16.6 million during the same period in the prior year. We believe that 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. Over the past years, ownership has resulted in lower overall equipment costs.

Historically, we have invested an amount that approximated the sum of depreciation and amortization expenses plus proceeds from equipment sales. Capital expenditures, primarily for construction equipment, are expected to total $55 million to $60 million for 2016 which would be in line with our historical practice.

We periodically sell and acquire equipment, typically to update our fleet. We received proceeds from the sale of used equipment of $3.3 million during the three months ending March 31, 2016 and $2.8 million during the same period in 2015.

On January 29, 2016, we purchased the net assets of Mueller for $4.1 million in cash and in the prior year, on February 28, 2015, we purchased the net assets of Aevenia for $22.3 million in cash.

Financing activities

Financing activities used cash of $13.6 million for the three months ended March 31, 2016, which was net of several transactions, which included:

· $12.0 million in repayment of long-term debt and the repayment of $0.3 million in capital leases;

· Dividend payments of $2.8 million to our stockholders during the three months ended March 31, 2016; and

· $1.4 million in proceeds from the issuance of 85,907 shares of common stock purchased by the participants in the Primoris Long-term Retention Plan.

Contractual Obligations

As of March 31, 2016, we had $263.0 million of outstanding long-term debt and capital lease obligations and there were no short-term borrowings.

A summary of contractual obligations as of March 31, 2016 was as follows:

	Total		1 Year		2 - 3 Years		4 - 5 Years		After 5 Years
	(In Thousands)
Long-term debt and capital lease obligations	$	263,040	$	52,989	$	95,449	$	65,410	$	49,192

Letters of credit	$	17,361	$	12,361	$	5,000	$	—	$	—

(1) The interest amount represents interest payments for our fixed rate debt assuming that principal payments are made as originally scheduled.

The table does not include obligations under multi-employer pension plans in which some of our employees participate. Our multi-employer pension plan contribution rates are generally specified in our collective bargaining agreements, and contributions are made to the plans based on employee payrolls. Our obligations for future periods cannot be determined because we cannot predict the number of employees that we will employ at any given time nor the plans in which they may participate.

We may also be required to make additional contributions to multi-employer pension plans if they become underfunded, and these contributions will be determined based on our union payroll. The Pension Protection Act of 2006 added special funding and operational rules for multi-employer plans that are classified as “endangered,” “seriously endangered” or “critical” status. Plans in these classifications must adopt measures to improve their funded status through a funding improvement or rehabilitation plan, which may require additional contributions from employers. The amounts of additional funds that we may be obligated to contribute cannot be reasonably estimated and is not included in the table above.

In November 2011, members of the Pipe Line Contractors Association “PLCA” including ARB, Rockford and Q3C (prior to the Company’s acquisition in 2012), withdrew from the Central States Southeast and Southwest Areas Pension Fund multiemployer pension plan (“Plan”). These withdrawals were made in order to mitigate additional liability in connection with the significantly underfunded Plan. The Company recorded a withdrawal liability of $7.5 million, which was increased to $7.6 million after the acquisition of Q3C, based on information provided by the Plan. The Plan asserted that the PLCA members did not affect a proper withdrawal in 2011, and in May 2014, the Plan asserted that the total liability for the Company was $11.8 million. A legal proceeding commenced, and a United States District Court ruled that the withdrawal of the PLCA members in 2011 was not effective. The PLCA appealed this decision, but as required by the Plan, the Company began making monthly payments, including interest, which totaled $1.8 million through December 31, 2015. The payments were expensed as they were made.

We have also excluded from the table any interest and fees associated with letters of credit and commitment fees under our credit facility since these amounts are variable.

Off-balance sheet transactions

As is common in our industry, we enter into certain off-balance sheet arrangements in the ordinary course of business that result in risks not directly reflected on our balance sheet. We have no off-balance sheet financing arrangement with variable interest entities. 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 March 31, 2016, we had letters of credit outstanding of $17.4 million, primarily for international project engineering jobs in our Energy segment and for providing security to our insurance carriers. These letters of credit are used by some of our vendors to ensure reimbursement for amounts that they are disbursing on our behalf, such as beneficiaries under our self-funded insurance program. In addition, from time to time, certain customers require us to post a letter of credit to ensure payments to our subcontractors or guarantee performance under our contracts. Letters of credit reduce our borrowing availability under our Credit Agreement and Canadian Credit Facility. If these letters of credit were drawn on by the beneficiary, we would be required to reimburse the issuer of the letter of credit, and we may be required to record a charge to earnings for the reimbursement. As of the date of this First Quarter 2016 Report, we do not believe that it is likely that any material claims will be made under a letter of credit;

· We enter into non-cancellable operating leases for some of our facilities, equipment and vehicles, including leases with related parties. At March 31, 2016, equipment operating leases had a remaining commitment of $12.2 million and facility rental commitments were $17.8 million;

· 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 March 31, 2016, we had $1.5 billion in outstanding bonds. As of the date of this First Quarter 2016 Report, we do not believe that it is likely that we would have to fund material claims under our surety arrangements;

· As discussed in the previous section, “Contractual Obligations”, certain of our subsidiaries are parties to collective bargaining agreements with unions which may create future obligations not recorded on our balance sheet;

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

· Employment agreements with executive officers or with executives from acquired companies may create obligations.

Receivable Collection Actions

At March 31, 2016, the Company is engaged in dispute resolution to enforce collection for two construction projects completed by the Company in 2014. For one project, a cost reimbursable contract, the Company has recorded a receivable of $32.9 million, and for the other project, the Company has a receivable balance due of $17.9 million. At March 31, 2016, the Company has not recorded revenues in excess of cost for these two projects; however, the Company has specific reserves for both projects of approximately $26 million included in “billings in excess of costs and estimated earnings.” At this time, the Company cannot predict the amount that it will collect nor the timing of any collection.

Effects of Inflation and Changing Prices

Our operations are affected by increases in prices, whether caused by inflation or other economic factors. We attempt to recover anticipated increases in the cost of labor, equipment, fuel and materials through price escalation provisions in certain major contracts or by considering the estimated effect of such increases when bidding or pricing new work or by entering into back-to-back contracts with suppliers and subcontractors.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

In the ordinary course of business, we are exposed to risks related to market conditions. These risks primarily include fluctuations in foreign currency exchange rates, interest rates and commodity prices. We may seek to manage these risks through the use of financial derivative instruments. These instruments may include foreign currency exchange contracts and interest rate swaps.

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 matter to limit significant exposure with any one party.

At March 31, 2016, we had no derivative financial instruments.

The carrying amounts for cash and cash equivalents, accounts receivable, short-term debt, accounts payable and accrued liabilities shown in the consolidated balance sheets approximate fair value at March 31, 2016 and December 31, 2015, due to the generally short maturities of these items. At March 31, 2016, we held no short term investments. In the periods where we have, we generally invest in in U.S. Treasury bills with various financial institutions that are backed by the federal government. We expect to hold our investments to maturity.

At March 31, 2016, all of our long-term debt was subject to fixed interest rates.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

As of March 31, 2016, 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 March 31, 2016, 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. 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. We anticipate continuing enhancement of our controls, especially as we complete the process of integrating our financial and operations information systems onto a common platform.

Changes in Internal Control Over Financial Reporting

During the fiscal quarter ended March 31, 2016, there were no changes to our internal control over financial reporting practices or processes that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
