PRIMORIS SERVICES CORPORATION

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. We are incorporated in the State of Delaware, and our corporate headquarters are located at 2300 N. Field Street, Suite 1900, Dallas, Texas 75201. 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.

Reportable Segments — We segregate our business into five reportable segments: the Power, Industrial and Engineering (“Power”) segment, the Pipeline and Underground (“Pipeline”) segment, the Utilities and Distribution (“Utilities”) segment, the Transmission and Distribution (“Transmission”) segment, and the Civil segment. See Note 18 – “Reportable Segments” for a brief description of the reportable segments and their operations.

The classification of revenue and gross profit for segment reporting purposes can at times require judgment on the part of management. Our segments may perform services across industries or perform joint services for customers in multiple industries. To determine reportable segment gross profit, certain allocations, including allocations of shared and indirect costs, such as facility costs, equipment costs and indirect operating expenses were made.

Acquisition of Willbros Group, Inc. — On June 1, 2018, we completed our acquisition of Willbros Group, Inc. (“Willbros”) for approximately $110.6 million, net of cash and restricted cash acquired. Willbros is a specialty energy infrastructure contractor serving the oil and gas and power industries through its utility transmission and distribution, oil and gas, and Canadian operations, which principally provides unit-price maintenance services in existing operating facilities and executes industrial and power projects. The utility transmission and distribution operations formed the Transmission segment, the oil and gas operations are included in the Pipeline segment, and the Canadian operations are included in the Power segment. See Note 5— “Business Combinations”.

Joint Ventures — We own a 50% interest in the Carlsbad Power Constructors joint venture (“Carlsbad”), which engineered and constructed a gas-fired power generation facility located in Southern California, and its operations are included as part of the Power segment. As a result of determining that we are the primary beneficiary of the variable interest entity (“VIE”), the results of the Carlsbad joint venture are consolidated in our financial statements. The project was substantially complete as of December 31, 2018 and the warranty period expires in December 2020.

We owned a 50% interest in the “ARB Inc. & B&M Engineering Co.” joint venture (“Wilmington”), which engineered and constructed a gas-fired power generation facility in Southern California, and its operations were included as part of the Power segment. As a result of determining that we were the primary beneficiary of the VIE, the results of the Wilmington joint venture were consolidated in our financial statements. The project has been completed, the project warranty period expired, and dissolution of the joint venture was completed in the first quarter of 2019.

Financial information for the joint ventures is presented in Note 11 – “Noncontrolling Interests”.

Note 2—Basis of Presentation

Interim condensed consolidated financial statements — The interim condensed consolidated financial statements for the three and six month periods ended June 30, 2019 and 2018 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 our Annual Report on Form 10-K, filed on February 28, 2019, which contains our audited consolidated financial statements for the year ended December 31, 2018, have been omitted.

This Second Quarter 2019 Report on Form 10-Q should be read in conjunction with our 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. 

10

Customer concentration — We operate in multiple industry segments encompassing the construction of commercial, industrial and public works infrastructure assets primarily throughout the United States. Typically, the top ten customers in any one calendar year generate revenue that is approximately 50% of total revenue; however, the group that comprises the top ten customers varies from year to year.

During the three and six months ended June 30, 2019, revenue generated by the top ten customers was approximately $372.4 million and $696.5 million, respectively, which represented 47.1% and 48.0%, respectively of total revenue during the period. During the three and six months ended June 30, 2019, a Midwest utility customer represented 8.0% and 6.7% of total revenue, respectively, and an electric utility customer represented 7.6% and 8.3% of total revenue, respectively.

During the three and six months ended June 30, 2018, revenue generated by the top ten customers was approximately $322.6 million and $581.6 million, respectively, which represented 50.4% and 49.7%, respectively, of total revenue during the period. During the three and six months ended June 30, 2018, a state department of transportation customer represented 9.4% and 9.3% of total revenue, respectively, and a California utility customer represented 8.7% and 9.0% of total revenue, respectively.

At June 30, 2019, approximately 8.7% of our accounts receivable was due from one customer, and that customer provided 8.3% of our revenue for the six months ended June 30, 2019.

On January 29, 2019, one of our utility customers filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. As of June 30, 2019, the utility customer comprised approximately 14.0% of our total accounts receivable. In addition to accounts receivable, there is approximately $15.8 million in unbilled revenue, net as of June 30, 2019. For the three and six months ended June 30, 2019, the customer accounted for approximately 5.9% and 5.7%, respectively, of our total revenue. A portion of the accounts receivable balance is past due, but we do not believe a reserve for the accounts receivable and unbilled revenue is appropriate at this time. However, we will closely monitor our current and future potential exposure.

Note 3—Recent Accounting Pronouncements

Recently adopted accounting pronouncements

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, with several clarifying updates. ASU 2016-02 requires 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 also requires disclosures that provide qualitative and quantitative information for the lease assets and liabilities recorded in the financial statements. The standard is effective for fiscal years beginning after December 15, 2018, and requires a modified retrospective transition method where a company applies the new lease standard at (i) the beginning of the earliest period presented in the financial statements, or (ii) the adoption date and recognizes a cumulative effect adjustment to the opening balance of retained earnings. We adopted the new standard as of January 1, 2019 using the modified retrospective transition method and elected to apply the new lease standard at the adoption date. See Note 16 — “Leases” for further details.

In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment". ASU 2017-04 removes the second step of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We adopted the standard on January 1, 2019, and it did not have an impact on our financial position, results of operations, or cash flows.

Recently issued accounting pronouncements not yet adopted

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments”, which introduced an expected credit loss methodology for the measurement and recognition of credit losses on most financial assets, including trade accounts receivables. The expected credit loss methodology under ASU 2016-13 is based on historical experience, current conditions and reasonable and supportable forecasts, and replaces the probable/incurred loss model for measuring and recognizing expected losses under current GAAP. The ASU also requires disclosure of information regarding how a company

11

developed its allowance, including changes in the factors that influenced management’s estimate of expected credit losses and the reasons for those changes. The ASU and its related clarifying updates are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. Based on our historical experience, we do not currently expect this ASU to have a material impact on our estimate of the allowance for uncollectable accounts.

In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement”, which eliminates certain disclosure requirements for recurring and nonrecurring fair value measurements. The ASU eliminates such disclosures as the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, and adds new disclosure requirements for Level 3 measurements. This ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for any eliminated or modified disclosures. We do not expect the adoption of this ASU to have a material impact on our disclosures.

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, our financial assets and liabilities that are required to be measured at fair value at June 30, 2019 and December 31, 2018 (in thousands):

	Fair Value Measurements at Reporting Date
			Significant
	Quoted Prices		Other		Significant
	in Active Markets		Observable		Unobservable
	for Identical Assets		Inputs		Inputs
	(Level 1)		(Level 2)		(Level 3)
Assets as of June 30, 2019:
Cash and cash equivalents	$	54,114	$	—	$	—
Contingent consideration	$	—	$	—	$	938
Liabilities as of June 30, 2019:
Interest rate swap	$	—	$	7,023	$	—
Assets as of December 31, 2018:
Cash and cash equivalents	$	151,063	$	—	$	—
Liabilities as of December 31, 2018:
Interest rate swap	$	—	$	2,829	$	—

Other financial instruments 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 our long-term debt approximates fair value based on comparison with current prevailing market rates for loans of similar risks and maturities.

In the second quarter of 2019, we sold certain assets that included an earnout of $2.0 million, contingent upon the buyer meeting certain performance targets. The estimated fair value of the contingent consideration on the sale date was approximately $0.9 million. We measured the fair value of the contingent consideration using the income approach, which discounts the future cash payments expected upon meeting the performance targets to present value. The fair

12

value of the contingent consideration was impacted by two unobservable inputs, management’s estimate of the probability of meeting the performance target and the estimated discount rate (a rate that approximates our cost of capital). Significant changes in either of those inputs in isolation would result in a different fair value measurement.

The interest rate swap is measured at fair value using the income approach, which discounts the future net cash settlements expected under the derivative contracts to a present value. These valuations primarily utilize indirectly observable inputs, including contractual terms, interest rates and yield curves observable at commonly quoted intervals. See Note 10 – “Derivative Instruments” for additional information.

2018 Acquisition

Acquisition of Willbros Group, Inc.

On June 1, 2018, we acquired all of the outstanding common stock of Willbros, a specialty energy infrastructure contractor serving the oil and gas and power industries for approximately $110.6 million, net of cash and restricted cash acquired. The total purchase price was funded through a combination of existing cash balances and borrowings under our revolving credit facility.

During the second quarter of 2019, we finalized the estimate of fair values of the assets acquired and liabilities assumed of Willbros. The tables below represent the purchase consideration and estimated fair values of the assets acquired and liabilities assumed. Significant changes since our initial estimates reported in the second quarter of 2018 primarily relate to fair value adjustments to our acquired contracts, which resulted in an increase to contract liabilities of $23.7 million. In addition, fair value adjustments to our acquired lease obligations and insurance liabilities reduced our liabilities assumed by approximately $11.9 million and $6.0 million, respectively, and fair value adjustments to our acquired intangible assets decreased our assets acquired by $6.8 million. As a result of these and other adjustments to the initial estimated fair values of the assets acquired and liabilities assumed, goodwill increased by approximately $18.0 million since the second quarter of 2018. Adjustments recorded to the estimated fair values of the assets acquired and liabilities assumed are recognized in the period in which the adjustments are determined and calculated as if the accounting had been completed as of the acquisition date.

We separated the operations of Willbros among two of our existing segments, and created a new segment for the utility transmission and distribution operations called the Transmission segment. The oil and gas operations are included in the Pipeline segment, and the Canadian operations are included in the Power segment. Goodwill associated with the Willbros acquisition principally consists of expected benefits from the expansion of our services into electric utility-focused offerings and the expansion of our geographic presence. Goodwill also includes the value of the assembled workforce. We allocated $59.0 million of goodwill to the Transmission segment, $1.8 million to the Power segment, and $0.9 million to the Pipeline segment. Based on the current tax treatment, goodwill is not expected to be deductible for income tax purposes.

As part of the Willbros acquisition, we acquired approximately $40.2 million of restricted cash that was pledged by Willbros to secure letters of credit. Subsequent to the acquisition, we issued new letters of credit under our Credit Facility to replace the Willbros letters of credit secured by the restricted cash. As of June 30, 2019, substantially all of the restricted cash had been released.

For the three and six months ended June 30, 2019, Willbros contributed revenue of $182.3 million and $340.0 million, respectively, and gross profit of $14.4 million and $22.0 million, respectively . For the period June 1, 2018, the acquisition date, to June 30, 2018, Willbros contributed revenue of $61.0 million and gross profit of $6.8 million.

Acquisition related costs were $7.7 million and $9.3 million for the three and six months ended June 30, 2018, respectively, related to the acquisition of Willbros and are included in “Merger and related costs” on the Condensed Consolidated Statements of Income. Such costs primarily consisted of severance and retention bonus costs for certain employees of Willbros and professional fees paid to advisors.

Supplemental Unaudited Pro Forma Information for the three and six months ended June 30, 2018

The following pro forma information for the three and six months ended June 30, 2018 presents our results of operations as if the acquisitions of Willbros had occurred at the beginning of 2018. The supplemental pro forma information has been adjusted to include:

● the pro forma impact of amortization of intangible assets and depreciation of property, plant and equipment;

● the pro forma impact of nonrecurring merger and related costs directly attributable to the acquisition;

● the pro forma impact of interest expense relating to the acquisition; and

● the pro forma tax effect of both income before income taxes, and the pro forma adjustments, calculated using a tax rate of 28.0% for the three and six months ended June 30, 2018.

The pro forma results are presented for illustrative purposes only and are not necessarily indicative of, or intended to represent, the results that would have been achieved had the Willbros acquisition been completed on January 1, 2018. For example, the pro forma results do not reflect any operating efficiencies and associated cost savings that we might have achieved with respect to the acquisition.

Note 6—Revenue

We generate revenue under a range of contracting types, including fixed-price, unit-price, time and material, and cost reimbursable plus fee contracts. A substantial portion of our revenue is derived from contracts that are fixed-price or unit-price and is recognized over time as work is completed because of the continuous transfer of control to the customer (typically using an input measure such as costs incurred to date relative to total estimated costs at completion to measure progress). For time and material and cost reimbursable plus fee contracts, revenue is recognized primarily on an input basis, based on contract costs incurred as defined within the respective contracts. Costs to obtain contracts are generally not significant and are expensed in the period incurred.

We evaluate whether two or more contracts should be combined and accounted for as one single performance obligation and whether a single contract should be accounted for as more than one performance obligation. ASC 606 defines a performance obligation as a contractual promise to transfer a distinct good or service to a customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Our evaluation requires significant judgment and the decision to combine a group of contracts or separate a contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. The majority of our contracts have a single performance obligation, as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contract and, therefore, is not distinct. However, occasionally we have contracts with multiple performance obligations. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using the observable standalone selling price, if available, or alternatively our best estimate of the standalone selling price of each distinct

15

performance obligation in the contract. The primary method used to estimate standalone selling price is the expected cost plus a margin approach for each performance obligation.

As of June 30, 2019, we had $1.93 billion of remaining performance obligations. We expect to recognize approximately 55% of our remaining performance obligations as revenue during the next four quarters and substantially all of the remaining balance by the second quarter of 2021.

Accounting for long-term contracts involves the use of various techniques to estimate total transaction price and costs. For long-term contracts, transaction price, estimated cost at completion and total costs incurred to date are used to calculate revenue 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 revenue 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 nature of our contracts gives rise to several types of variable consideration, including contract modifications (change orders and claims), liquidated damages, volume discounts, performance bonuses, incentive fees, and other terms that can either increase or decrease the transaction price. We estimate variable consideration as the most likely amount to which we expect to be entitled. We include estimated amounts in the transaction price to the extent we believe we have an enforceable right, and it is probable that a significant reversal of cumulative revenue recognized will not occur. Our estimates of variable consideration and the determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us at this time.

Contract modifications result from changes in contract specifications or requirements. We consider unapproved change orders to be contract modifications for which customers have not agreed to both scope and price. We consider claims to be contract modifications for which we seek, 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. Claims can also be caused by non-customer-caused changes, such as rain or other weather delays. Costs associated with contract modifications are included in the estimated costs to complete the contracts and are treated as project costs when incurred. In most instances, contract modifications are for goods or services that are not distinct, and, therefore, are accounted for as part of the existing contract. The effect of a contract modification on the transaction price, and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis. In some cases, settlement of contract modifications may not occur until after completion of work under the contract.

As a significant change in one or more of these estimates could affect the profitability of our contracts, we review and update our contract-related estimates regularly. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the cumulative impact of the profit adjustment is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance are recognized using the adjusted estimate. In the three and six months ended June 30, 2019, revenue recognized from performance obligations satisfied in previous periods was $4.2 million and $10.7 million, respectively. If at any time the estimate of contract profitability indicates an anticipated loss on a contract, the projected loss is recognized in full, including any previously recognized profit, in the period it is identified and recognized as an “accrued loss provision” which is included in “Contract liabilities” on the Condensed Consolidated Balance Sheets. For contract revenue recognized over time, the accrued loss provision is adjusted so that the gross profit for the contract remains zero in future periods.

At June 30, 2019, we had approximately $84.1 million of unapproved contract modifications included in the aggregate transaction prices. These contract modifications were in the process of being negotiated in the normal course of business. Approximately $79.3 million of the contract modifications had been recognized as revenue on a cumulative catch-up basis through June 30, 2019.

In all forms of contracts, we estimate the collectability of contract amounts at the same time that we estimate project costs. If we anticipate that there may be issues associated with the collectability of the full amount calculated as

16

the transaction price, we 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.

The timing of when we bill our customers is generally dependent upon agreed-upon contractual terms, milestone billings based on the completion of certain phases of the work, or when services are provided. Sometimes, billing occurs subsequent to revenue recognition, resulting in unbilled revenue, which is a contract asset. Also, we sometimes receive advances or deposits from our customers before revenue is recognized, resulting in deferred revenue, which is a contract liability.

The caption “Contract assets” in the Condensed Consolidated Balance Sheets represents the following:

● unbilled revenue, which arise when revenue has been recorded but the amount will not be billed until a later date;

● retainage amounts for the portion of the contract price earned by us for work performed, but held for payment by the customer as a form of security until we reach certain construction milestones; and

● contract materials for certain job specific materials not yet installed, which are valued using the specific identification method relating the cost incurred to a specific project.

Contract assets consist of the following (in thousands):

	June 30,		December 31,
	2019		2018
Unbilled revenue	$	311,915	$	249,577
Retention receivable		84,805		88,953
Contract materials (not yet installed)		18,422		25,715
	$	415,142	$	364,245

Contract assets increased by $50.9 million compared to December 31, 2018 due primarily to higher unbilled revenue, partially offset by a reduction in contract materials net yet installed.

The caption “Contract liabilities” in the Condensed Consolidated Balance Sheets represents deferred revenue on billings in excess of contract revenue recognized to date, and the accrued loss provision.

Contract liabilities consist of the following (in thousands):

	June 30,		December 31,
	2019		2018
Deferred revenue	$	192,772	$	182,232
Accrued loss provision		5,013		7,307
	$	197,785	$	189,539

Contract liabilities increased by $8.2 million compared to December 31, 2018 primarily due to an increase in deferred revenue, partially offset by a reduction in the accrued loss provision.

Revenue recognized for the six months ended June 30, 2019, that was included in the contract liability balance at December 31, 2018 was approximately $135.1 million.

Each of these contract types has a different risk profile. Typically, we assume more risk with fixed-price contracts. Unforeseen events and circumstances can alter the estimate of the costs and potential profit associated with a particular fixed-price contract. However, these types of contracts offer additional profits when we complete the work for less cost than originally estimated. Unit-price and cost reimbursable contracts generally subject us to lower risk. Accordingly, the associated fees are usually lower than fees earned on fixed-price contracts. Under these contracts, our profit may vary if actual costs vary significantly from the negotiated rates.

The weighted average interest rate on total debt outstanding at June 30, 2019 and December 31, 2018 was 4.2% and 4.1%, respectively.

Credit Agreement

Our credit agreement consists of a $220.0 million term loan and a $200.0 million revolving credit facility (“Revolving Credit Facility”), whereby the lenders agreed to make loans on a revolving basis from time to time and to issue letters of credit for up to the $200.0 million committed amount. The credit agreement also includes an accordion feature that would allow us to increase the borrowing capacity thereunder by $75.0 million, subject to obtaining additional or increased lender commitments. The maturity date of the credit agreement is July 9, 2023. At June 30, 2019, there was $55.0 million of outstanding borrowings under the Revolving Credit Facility, commercial letters of credit outstanding were $41.4 million, and available borrowing capacity was $103.6 million.

The credit agreement contains various restrictive and financial covenants including, among others, a senior debt/EBITDA ratio and debt service coverage requirements. In addition, the credit agreement includes restrictions on investments, change of control provisions and provisions in the event we dispose of more than 20% of our total assets. We were in compliance with the covenants for the Credit Agreement at June 30, 2019.

Canadian Credit Facility

We have a demand credit facility for $4.0 million in Canadian dollars with a Canadian bank for purposes of issuing commercial letters of credit in Canada.  At June 30, 2019, commercial letters of credit outstanding were $0.2 in Canadian dollars, and the available borrowing capacity was $3.8 million in Canadian dollars.  The credit facility contains a working capital restrictive covenant for OnQuest Canada, ULC, our wholly owned subsidiary.  At June 30, 2019, OnQuest Canada, ULC was in compliance with the covenant.

Note 10 — Derivative Instruments

We are exposed to certain market risks related to changes in interest rates. To monitor and manage these market risks, we have established risk management policies and procedures. We do not enter into derivative instruments for any purpose other than hedging interest rate risk. None of our derivative instruments are used for trading purposes.

Interest Rate Risk. We are exposed to variable interest rate risk as a result of variable-rate borrowings under our Credit Agreement. To manage fluctuations in cash flows resulting from changes in interest rates on a portion of our variable-rate debt, we entered into an interest rate swap agreement on September 13, 2018 with an initial notional amount of $165.0 million, or 75% of the debt outstanding under our Term Loan, which was not designated as a hedge for accounting purposes. The notional amount of the swap will be adjusted down each quarter by 75% of the required principal payments made on the Term Loan. The swap effectively changes the variable-rate cash flow exposure on the debt obligations to fixed rates. The fair value of outstanding interest rate swap derivatives can vary significantly from period to period depending on the total notional amount of swap derivatives outstanding and fluctuations in market

21

interest rates compared to the interest rates fixed by the swaps. As of June 30, 2019, and December 31, 2018, our outstanding interest rate swap agreement contained a notional amount of $156.8 million and $160.9 million, respectively, with a maturity date of July 10, 2023.

Credit Risk. By using derivative instruments to economically hedge exposures to changes in interest rates, we are exposed to counterparty credit risk. Credit risk is the failure of a counterparty to perform under the terms of a derivative contract. When the fair value of a derivative contract is positive, the counterparty owes us, which creates credit risk for us. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, we do not possess credit risk. We minimize the credit risk in derivative instruments by entering into transactions with high quality counterparties. We have entered into netting agreements, including International Swap Dealers Association (“ISDA”) Agreements, which allow for netting of contract receivables and payables in the event of default by either party.

The following table summarizes the fair value of our derivative contracts included in the Condensed Consolidated Balance Sheets (in thousands):

		Liability Derivatives

Note 11 — Noncontrolling Interests

We own a 50% interest in the Carlsbad joint venture and we owned a 50% interest in the Wilmington joint venture, each of which operates in the Power segment. Both joint ventures have been determined to be a VIE and we were determined to be the primary beneficiary as a result of our significant influence over the joint venture operations.

Each joint venture is a partnership, and consequently, only the tax effect of our share of the income was recognized by us. The net assets of the joint ventures are restricted for use by the specific project and are not available for our general operations.

Carlsbad Joint Venture

The Carlsbad joint venture’s operating activities began in 2015 and are included in our Condensed Consolidated Statements of Income as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Revenue	$	227	$	29,437	$	4,251	$	71,257
Net income attributable to noncontrolling interests	$	37	$	2,330	$	1,026	$	5,444

The Carlsbad joint venture made distributions of $3.5 million to the noncontrolling interest and $3.5 million to us during the three and six months ended June 30, 2019. No distributions were made during the six months ended June 30, 2018. In addition, we did not make any capital contributions to the Carlsbad joint venture during the six months ended June 30, 2019 and 2018. The project was substantially complete as of December 31, 2018 and the warranty period expires in December 2020.

Revenue	$	—	$	437	$	—	$	1,921
Net income attributable to noncontrolling interests	$	—	$	146	$	—	$	560

The project has been completed, the project warranty period has expired, and the dissolution of the joint venture was completed in the first quarter of 2019. The Wilmington joint venture made a final immaterial distribution to the noncontrolling interest and to us during the first quarter of 2019. No distributions were made during the six months ended June 30, 2018. In addition, we did not make any capital contributions to the Wilmington joint venture during the six months ended June 30, 2019 and 2018. The carrying value of the assets and liabilities associated with the operations of the Wilmington joint venture were included in our Condensed Consolidated Balance Sheet and were immaterial at December 31, 2018.

Summary – Joint Venture Balance Sheets

The following table summarizes the total balance sheet amounts for the Carlsbad and Wilmington joint ventures, which are included in our Condensed Consolidated Balance Sheets, and the total consolidated balance sheet amounts (in thousands):

Note 12—Stock-Based Compensation

In May 2013, the shareholders approved and we adopted the Primoris Services Corporation 2013 Long-term Incentive Equity Plan (“Equity Plan”). Our Board of Directors has granted 423,105 Restricted Stock Units (“Units”), net of forfeitures to employees under the Equity Plan. The grants were documented in RSU Award Agreements, which provide for a vesting schedule and require continuing employment of the employee. The Units are subject to earlier acceleration, termination, cancellation or forfeiture as provided in the underlying RSU Award Agreement.

At June 30, 2019, a total of 254,955 Units were vested. The vesting schedule for the remaining Units are as follows:

	Number of Units
For the Years Ending December 31,	to Vest
2019 (remaining six months)	4,393
2020	11,067
2021	122,649
2022	27,700
2023	2,341
	168,150

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. We recognized $0.4 million and $0.2 million in compensation expense for the three months ended June 30, 2019 and 2018, respectively, and $0.9 million and $0.4 million for the six months ended June 30, 2019 and 2018, respectively. At June 30, 2019, approximately $2.9 million of unrecognized compensation expense remained for the Units, which will be recognized over a weighted average period of 2.2 years.

Vested Units accrue “Dividend Equivalent Units” (as defined in the Equity Plan), which will be accrued as additional Units until the Units are converted to Common Stock.  At June 30, 2019, a total of 1,745 Dividend Equivalent Units were accrued.

Note 13—Income Taxes

We are subject to tax liabilities imposed by multiple jurisdictions. We determine our best estimate of the annual effective tax rate at each interim period using expected annual pre-tax earnings, statutory tax rates, and available tax planning opportunities. Certain significant or unusual items are separately recognized in the quarter in which they occur which can cause variability in the effective tax rate from quarter to quarter. We recognize interest and penalties related to uncertain tax positions, if any, as an income tax expense.

We do not include the income tax expense or benefit related to the net earnings or loss attributable to noncontrolling interest in our income tax expense as the entities are considered pass-through entities and, as such, the income tax expense or benefit is attributable to its owners. The effective tax rate on income including noncontrolling interests for the six months ended June 30, 2019 and 2018 was 28.0% and 17.5%, respectively. Excluding noncontrolling interest, the effective tax rate on income attributable to Primoris for the six months ended June 30, 2019 and 2018 was 29.0% and 24.0%, respectively. For the first six months of 2019, our tax rate differs from the U.S. federal statutory rate of 21.0% primarily due to the impact of state income taxes and nondeductible components of per diem expenses. For the first six months of 2018, our tax rate differs from the U.S. federal statutory rate of 21.0% primarily due to the impact of state income taxes, investment tax credits, and nondeductible components of per diem expenses.

Our U.S. federal income tax returns are generally no longer subject to examination for tax years before 2015. The statutes of limitation of state and foreign jurisdictions generally vary between 3 to 5 years. Accordingly, our state and foreign income tax returns are generally no longer subject to examination for tax years before 2013.

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for temporary differences between the financial reporting bases and tax bases of assets and liabilities based

24

on enacted tax rates expected to be in effect when such amounts are realized or settled. However, deferred tax assets are recognized only to the extent that it is more likely than not that they will be realized based upon consideration of available evidence, including future reversals of existing taxable temporary differences, future projected taxable income, the length of the tax asset carryforward periods, and tax planning strategies. The effects of remeasurement of deferred tax assets and liabilities resulting from changes in tax rates are recognized in income in the period of enactment.

Note 14—Dividends and Earnings Per Share

We have paid or declared cash dividends during 2019 and 2018 as follows:

Declaration Date	Record Date	Payable Date	Amount Per Share
February 21, 2018	March 30, 2018	April 13, 2018	$	0.060
May 4, 2018	June 29, 2018	July 13, 2018	$	0.060
August 2, 2018	September 28, 2018	October 15, 2018	$	0.060
November 2, 2018	December 31, 2018	January 15, 2019	$	0.060

May 3, 2019	June 28, 2019	July 15, 2019	$	0.060

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

The table below presents the computation of basic and diluted earnings per share for the three and six months ended June 30, 2019 and 2018 (in thousands, except per share amounts).

Note 15—Stockholders’ Equity

Common stock

We issued 114,106 and 71,757 shares of common stock in the six months ended June 30, 2019 and 2018, respectively, under our long-term retention plan (“LTR Plan”). The shares were purchased by the participants in the LTR Plan with payment made to us of $1.8 million and $1.5 million in the six months ended June 30, 2019 and 2018, respectively. Our LTR Plan for managers and executives allows participants to use a portion of their annual bonus amount to purchase our common stock at a discount from the market price. The shares purchased in the six months ended June 30, 2019 were for bonus amounts earned in 2018, and the number of shares was calculated at 75% of the average daily closing market price during December 2018. The shares purchased in the six months ended June 30, 2018

25

were for bonus amounts earned in 2017, and the number of shares was calculated at 75% of the average closing market price of December 2017.

In February 2019 and 2018, we issued 13,278 and 10,062 shares of common stock, respectively, as part of the quarterly compensation of the non-employee members of the Board of Directors.

During the three and six months ended June 30, 2019, a total of 122,319 Units, net of forfeitures for tax withholdings, were converted to common stock. There were no Units converted to common stock during the six months ended June 30, 2018.

As discussed in Note 12 — “Stock–Based Compensation”, as of June 30, 2019, the Board of Directors has granted a total of 423,105 shares of Units, net of forfeitures under the Equity Plan and a total of 1,745 Dividend Equivalent Units were accrued at June 30, 2019.

Note 16—Leases

We lease administrative and fabrication facilities, which are generally longer-term, project specific facilities or yards, and construction equipment under non-cancelable operating leases. On January 1, 2019, we adopted ASC 842, “Leases” using the modified retrospective method and elected to apply the new lease standard at the adoption date. The cumulative impact of adopting ASC 842 was immaterial and did not require an adjustment to retained earnings. In adopting ASC 842, we changed our accounting policy for leases. Under the modified retrospective method, results for periods prior to January 1, 2019, are not adjusted and continue to be reported in accordance with our historic accounting under ASC 840, “Leases”.

We elected certain transition practical expedients permitted with the new standard, which among other things, allowed us to carry forward the historical lease classification. In addition, we elected the hindsight practical expedient to determine the reasonably certain lease term for existing leases. We also made an accounting policy election in which leases with an initial term of 12 months or less are not recorded on the balance sheet and lease payments are recognized in the Condensed Consolidated Statements of Income on a straight-line basis over the lease term.

We determine if an arrangement is a lease at inception. We have lease agreements with lease and non-lease components, which are generally accounted for separately. Operating leases are included in operating lease assets, accrued liabilities, and noncurrent operating lease liabilities on our Condensed Consolidated Balance Sheets.

Operating lease assets and operating lease liabilities are recognized at commencement date based on the present value of the future minimum lease payments over the lease term. In determining our lease term, we include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date to determine the present value of future payments. Lease expense from minimum lease payments is recognized on a straight-line basis over the lease term.

Our leases have remaining lease terms that expire at various dates through 2029, some of which may include options to extend the leases for up to 5 years. The exercise of lease extensions is at our sole discretion. Periodically, we sublease excess facility space, but any sublease income is generally not significant. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

The components of lease expense are as follows (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,
	2019			2018			2019			2018
Operating lease expense	$	17,654	(1)	$	9,836	(2)	$	34,167	(1)	$	16,668	(2)

Note 17—Commitments and Contingencies

NTTA settlement — On February 7, 2012, we were 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”). On February 25, 2015, the Lawsuit was settled, and we recorded a liability for $17.0 million. A second defendant agreed to provide up to $5.4 million to pay for the total expected remediation cost of approximately $22.4 million. We will pay a third-party contractor approved by the NTTA to complete the remediation. In the event that the total remediation costs exceed the $22.4 million, the second defendant would pay 20% of the excess amount and we would pay for 80% of the excess amount. During the six months ended June 30, 2019, we increased our liability by $1.6 million. We also spent $5.0 million for remediation during the six months ended June 30, 2019. While we continue to monitor the progress toward remediation and the total remediation costs, at this time we cannot determine the eventual remediation cost. At June 30, 2019, the remaining accrual balance was $15.1 million.

Legal proceedings —We are subject to other claims and legal proceedings arising out of our business. We provide for costs related to contingencies when a loss from such claims is probable and the amount is reasonably estimable. In determining whether it is possible to provide an estimate of loss, or range of possible loss, we review and evaluate our 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 probable but not 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 defenses to such claims and believes that the reasonably possible outcome of such claims will not, individually or in the aggregate, have a material adverse effect on our consolidated results of operations, financial condition or cash flow.

27

Bonding — At June 30, 2019 and December 31, 2018, the Company had bid and completion bonds issued and outstanding totaling approximately $598.7 million and $554.9 million, respectively.

Note 18—Reportable Segments

We segregate our business into five reportable segments: the Power segment, the Pipeline segment, the Utilities segment, the Transmission segment, and the Civil segment. Each of our reportable segments is comprised of similar business units that specialize in services unique to the segment. Driving the end-user focused segments are differences in the economic characteristics of each segment, the nature of the services provided by each segment; the production processes of each segment; the type or class of customer using the segment’s services; the methods used by the segment to provide the services; and the regulatory environment of each segment’s customers.

The classification of revenue and gross profit for segment reporting purposes can at times require judgment on the part of management. Our segments may perform services across industries or perform joint services for customers in multiple industries. To determine reportable segment gross profit, certain allocations, including allocations of shared and indirect costs, such as facility costs, equipment costs and indirect operating expenses, were made.

The following is a brief description of the reportable segments:

The Power segment operates throughout the United States and in Canada and specializes in a range of services that include full EPC project delivery, turnkey construction, retrofits, upgrades, repairs, outages, specialty services, fabrication, material lining, and maintenance for entities in the power, solar, petroleum, petrochemical, water, and other industries.

The Pipeline segment operates throughout the United States and specializes in a range of services, including pipeline construction, pipeline maintenance, pipeline integrity, pipeline facility work, compressor stations, pump stations, metering facilities, and other pipeline related services for entities in the petroleum and petrochemical industries.

The Utilities segment operates primarily in California, the Midwest, the Atlantic Coast, and the Southeast regions of the United States and specializes in a range of services, including gas utility line installation, replacement and maintenance, gas distribution, and fiber optic cable installation.

The Transmission segment operates primarily in the Southeastern, Midwest, Atlantic Coast, and Gulf Coast regions of the United States and specializes in a range of services in electric transmission and distribution, streetlight maintenance and construction, substation construction and specialty services, fiber optic cable installation, comprehensive engineering, procurement, maintenance and construction, repair, and restoration of utility infrastructure.

The Civil segment operates primarily in the Southeastern and Gulf Coast regions of the United States and specializes in highway and bridge construction, airport runway and taxiway construction, demolition, site clearing and grading, heavy earthwork, soil stabilization, mass excavation, and drainage projects.

All intersegment revenue and gross profit, which were immaterial, have been eliminated in the following tables.

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, specialty services, fabrication, maintenance, replacement, and engineering services to major public and private utilities, petrochemical companies, refiners, energy companies, municipalities, state departments of transportation and other customers. We install, replace, repair and rehabilitate natural gas infrastructure, refined product, water and wastewater pipeline systems; large diameter gas and liquid pipeline facilities; electric transmission and distribution infrastructure; and heavy civil projects, earthwork, as well as site clearing, grading and soil stabilization. We also construct mechanical facilities and other structures, including power plants, petrochemical facilities, hydrogen plants, refineries, solar facilities, battery storage facilities, electrical substations, 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 state departments of transportation, and engineering companies. We have completed major underground and industrial projects for a number of large natural gas transmission and petrochemical companies in the United States, major electrical and gas projects for a number of large utility companies in the 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 daily work orders to as long as 60 months, or longer 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 revenue in any given year.

31

We generate revenue under a range of contracting options, including fixed-price, unit-price, time and material, and cost reimbursable plus fee contracts. A substantial portion of our revenue is derived from contracts that are fixed-price or unit-price and is recognized over time as work is completed because of the continuous transfer of control to the customer. For time and material and cost reimbursable plus fee contracts, revenue is recognized primarily on an input basis, based on contract costs incurred as defined within the respective contracts.

Our reportable segments include the Power, Industrial, and Engineering (“Power”) segment, the Pipeline and Underground (“Pipeline”) segment, the Utilities and Distribution (“Utilities”) segment, the Transmission and Distribution (“Transmission”) segment, and the Civil segment. See Note 18 – “Reportable Segments” for a brief description of the reportable segments and their operations.

The classification of revenue and gross profit for segment reporting purposes can at times require judgment on the part of management. Our segments may perform services across industries or perform joint services for customers in multiple industries. To determine reportable segment gross profit, certain allocations, including allocations of shared and indirect costs, such as facility costs, equipment costs and indirect operating expenses were made.

On June 1, 2018, we acquired Willbros Group Inc. (“Willbros”) for approximately $110.6 million, net of cash and restricted cash acquired. Willbros is a specialty energy infrastructure contractor serving the oil and gas and power industries through its utility transmission and distribution, oil and gas, and Canadian operations, which principally provides unit-price maintenance services in existing operating facilities and executes industrial and power projects. The utility transmission and distribution operations formed the Transmission segment, the oil and gas operations are included in the Pipeline segment, and the Canadian operations are included in the Power segment. Willbros expands our services into electric utility-focused offerings and increases our geographic presence in the United States and Canada.

We own a 50% interest in the Carlsbad Power Constructors joint venture (“Carlsbad”), which engineered and constructed a gas-fired power generation facility located in Southern California, and its operations are included as part of the Power segment. As a result of determining that we are the primary beneficiary of the variable interest entity (“VIE”), the results of the Carlsbad joint venture are consolidated in our financial statements. The project was substantially complete as of December 31, 2018 and the warranty period expires in December 2020.

We owned a 50% interest in the “ARB Inc. & B&M Engineering Co.” joint venture (“Wilmington”), which engineered and constructed a gas-fired power generation facility in Southern California, and its operations were included as part of the Power segment. As a result of determining that we were the primary beneficiary of the VIE, the results of the Wilmington joint venture were consolidated in our financial statements. The project has been completed, the project warranty period expired, and dissolution of the joint venture was completed in the first quarter of 2019.

Financial information for the joint ventures is presented in Note 11 – “Noncontrolling Interests”.

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 and electric 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, periodically, each of these industries and government agencies is 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.

Fluctuations in market prices of oil, gas and other fuel sources have affected demand for our services. The significant volatility in the price of oil, gas and liquid natural gas that occurred in the past few years could create uncertainty with respect to demand for our oil and gas pipeline services both in the near-term and for future projects. We have started to see increased activity in our upstream operations, such as the construction of gathering lines within the oil

32

shale formations and believe that over time, the need for pipeline infrastructure for mid-stream and gas utility companies will result in a continuing need for our services. However, a prolonged period of depressed oil prices could delay midstream pipeline opportunities.

We are also monitoring the impact of recently imposed domestic and foreign trade tariffs, which could raise the price of raw materials, such as steel, utilized on construction projects or delay the start of certain projects. The continuing changes in the regulatory environment also affect the demand for our services, either by increasing our work or delaying projects. For example, environmental laws and regulation can provide challenges to major pipeline projects, resulting in delays that impact the timing of revenue recognition. In addition, the regulatory environment in California may result in delays for the construction of gas-fired power plants while regulators continue to search for significant renewable resources, but renewable resources may also create a demand for our construction and specialty services such as the need for battery storage of renewable generated electricity.

On January 29, 2019, one of our utility customers filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. As of June 30, 2019, the utility customer comprised approximately 14.0% of our total accounts receivable. In addition to accounts receivable, there is approximately $15.8 million in unbilled revenue, net as of June 30, 2019. For the three and six months ended June 30, 2019, the customer accounted for approximately 5.9% and 5.7% of our total revenue, respectively. A portion of the accounts receivable balance is past due, but we do not believe a reserve for the accounts receivable and unbilled revenue is appropriate at this time. However, we will closely monitor our current and future potential exposure.

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 and specialty services. These seasonal impacts can affect revenue and profitability in all of our businesses since 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 calendar year due to clients’ internal budget cycles. As a result, we usually experience higher revenue and earnings in the third and fourth quarters of the year as compared to the first two quarters.

Our project values range in size from a few hundred dollars to much larger projects. The bulk of our work is comprised of project sizes that average less than $10 million. We also perform 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 our financial condition and operating results may vary from quarter to quarter. Results from one quarter may not be indicative of 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 revenue 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. Actual results could differ significantly from our estimates, and our estimates could change if they were made under different assumptions or conditions. Our critical accounting policies are described in our Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2018. There have been no material changes to our critical accounting policies since December 31, 2018.

Results of Operations

Consolidated Results

The following discussion compares the results of the three and six months ended June 30, 2019 to the three and six months ended June 30, 2018.

Revenue

Revenue was $789.9 million for the three months ended June 30, 2019, an increase of $141.1 million, or 21.7%, compared to the same period in 2018. The increase was primarily due to incremental revenue from the Willbros acquisition ($121.3 million) and organic growth in the Pipeline segment.

Revenue was $1,451.5 million for the six months ended June 30, 2019, an increase of $298.6 million, or 25.9%, compared to the same period in 2018. The increase was primarily due to incremental revenue from the Willbros acquisition ($279.0 million) and organic growth in the Pipeline segment. The overall increase was partially offset by lower revenue in our Power and Utilities segments.

Gross Profit

Gross profit was $80.5 million for the three months ended June 30, 2019, an increase of $9.1 million, or 12.8%, compared to the same period in 2018. The increase was primarily due to revenue growth. Gross profit for the three months ended June 30, 2019 from the Willbros acquisition totaled $7.7 million. Gross profit as a percentage of revenue decreased to 10.2% in the three months ended June 30, 2019 from 11.0% in the same period in 2018 due primarily to unfavorable weather conditions in the Transmission, Pipeline and Utilities segments.

Gross profit was $133.0 million for the six months ended June 30, 2019, an increase of $17.0 million, or 14.7%, compared to the same period in 2018. The increase was primarily due to revenue growth. Gross profit for the six months ended June 30, 2019 from the Willbros acquisition totaled $15.2 million. Gross profit as a percentage of revenue decreased to 9.2% in the six months ended June 30, 2019 from 10.1% in the same period in 2018 due to unfavorable weather conditions in the Transmission, Pipeline and Utilities segments.

Selling, general and administrative expenses

Selling, general and administrative (“SG&A”) expenses were $48.7 million during the three months ended June 30, 2019, an increase of $5.2 million, or 12.0%, compared to 2018 primarily due to $3.7 million of incremental expense from the Willbros acquisition and a $1.7 million increase in compensation related expenses, including discretionary incentive compensation. SG&A expense as a percentage of revenue decreased to 6.2% compared to 6.7% for the corresponding period in 2018 due to increased revenue.

SG&A expenses were $91.7 million during the six months ended June 30, 2019, an increase of $11.2 million, or 13.9%, compared to 2018 primarily due to $10.9 million of incremental expense from the Willbros acquisition. SG&A expense as a percentage of revenue decreased to 6.3% compared to 7.0% for the corresponding period in 2018 due to increased revenue.

Merger and related costs

No merger and related costs were incurred for the three and six months ended June 30, 2019, compared to $7.7 million and $9.4 million in the same periods in 2018, which consisted primarily of severance and retention bonus costs for certain employees of Willbros and professional fees paid to advisors associated with the acquisition of Willbros.

34

Other income and expense

Non-operating income and expense items for the three and six months ended June 30, 2019 and 2018 were as follows (in thousands):

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2019		2018		2019		2018
Foreign exchange (loss) gain		(403)		1,256	$	(588)	$	1,513
Other income (expense), net		177		(771)		(193)		(783)
Interest income		219		340		568		612
Interest expense		(6,716)		(3,191)		(12,308)		(5,189)
Total other income (expense)	$	(6,723)	$	(2,366)	$	(12,521)	$	(3,847)

Foreign exchange gains reflect currency exchange fluctuations associated with our Canadian engineering operation, which operates principally in United States dollars.

Interest expense for the three and six months ended June 30, 2019 increased compared to the same periods in 2018 due to higher average debt balances and weighted average interest rates in 2019. In addition, we had a $2.7 million and $4.2 million unrealized loss on the change in the fair value of our interest rate swap agreement during the three and six months ended June 30, 2019, respectively.

Provision for income taxes

We are subject to tax liabilities imposed by multiple jurisdictions. We determine our best estimate of the annual effective tax rate at each interim period using expected annual pre-tax earnings, statutory tax rates, and available tax planning opportunities. Certain significant or unusual items are separately recognized in the quarter in which they occur which can cause variability in the effective tax rate from quarter to quarter. We recognize interest and penalties related to uncertain tax positions, if any, as an income tax expense.

The effective tax rate on income attributable to Primoris (excluding noncontrolling interests) was 29.0% for the six months ended June 30, 2019. The rate differs from the U.S. federal statutory rate of 21.0% primarily due to state income taxes and nondeductible components of per diem expenses.

We recorded income tax expense for the three months ended June 30, 2019 of $7.3 million compared to $3.7 million for the three months ended June 30, 2018. The $3.6 million increase in income tax expense was primarily driven by a $9.6 million increase in pre-tax income (excluding noncontrolling interests).

We recorded income tax expense for the six months ended June 30, 2019 of $8.1 million compared to $3.9 million for the six months ended June 30, 2018. The $4.2 million increase in income tax expense was primarily driven by a $11.5 million increase in pre-tax income (excluding noncontrolling interests).

Revenue increased by $5.2 million, or 3.1%, for the three months ended June 30, 2019, compared to the same period in 2018. The increase is primarily due to a West Texas solar facility project that began in 2019 ($34.1 million) and revenue from the acquisition of Willbros in June of 2018 ($26.4 million). The overall increase was partially offset by the substantial completions of our Carlsbad joint venture project and a West Texas solar facility project in 2018 ($47.2 million combined) and lower revenue from a LNG plant project in the Northeast in 2019.

Revenue decreased by $16.0 million, or 4.8%, for the six months ended June 30, 2019, compared to the same period in 2018. The decrease is primarily due to the substantial completion of our Carlsbad joint venture project in 2018 ($67.0 million), partially offset by revenue from the acquisition of Willbros in June of 2018 ($52.2 million).

Gross profit for the three months ended June 30, 2019, increased by $2.6 million, or 12.9% compared to the same period in 2018. The increase is primarily due to higher revenue and margins. Gross profit as a percentage of revenue increased to 13.5% during the three months ended June 30, 2019, compared to 12.3% in the same period in 2018 primarily due to more favorable margins realized by our solar project in 2019 compared to the solar project completed in 2018.

Gross profit for the six months ended June 30, 2019, decreased by $1.2 million, or 2.8% compared to the same period in 2018. The decrease is attributable to lower revenue. Gross profit as a percentage of revenue during the six months ended June 30, 2019 was comparable to the same period in 2018.

Revenue increased by $3.0 million, or 2.5%, for the three months ended June 30, 2019, compared to the same period in 2018. The increase is primarily due to a project with a major refining customer that began in 2019 ($9.0 million) and progress on a port project and an ethylene plant project that began in 2018, partially offset by lower Texas Department of Transportation (“DOT”) volumes.

Revenue increased by $6.4 million, or 2.8%, for the six months ended June 30, 2019, compared to the same period in 2018. The increase is primarily due to a project with a major refining customer that began in 2019 ($17.2 million), and progress on a port project and an ethylene plant project that began in 2018, partially offset by lower Texas DOT and Arkansas DOT volumes.

Gross profit increased by $4.8 million for the three months ended June 30, 2019, compared to the same period in 2018 primarily due to higher revenue and margins. Gross profit as a percentage of revenue increased to 3.9% during the three months ended June 30, 2019, compared to (0.1%) in the same period in 2018 due primarily to higher costs on an airport project in the second quarter of 2018.

Gross profit increased by $3.7 million for the six months ended June 30, 2019, compared to the same period in 2018 primarily due to higher revenue and margins. Gross profit as a percentage of revenue increased to 3.0% during the six months ended June 30, 2019, compared to 1.5% in the same period in 2018 due primarily to higher costs on an airport project in 2018.

Revenue at the five Belton area projects was $15.9 million and $31.9 million for the three and six months ended June 30, 2019, respectively, representing 12.9% and 13.3% of total Civil revenue, respectively. Revenue for which no margin was recognized was $9.3 million and $15.1 million for the three and six months ended June 30, 2019, respectively. During the three and six months ended June 30, 2019, four Belton area jobs were in a loss position and reported $3.7 million and $2.0 million of gross profit, respectively. Two of the Belton area jobs in a loss position were completed during 2017, and the two remaining loss jobs are scheduled to be completed in 2019. At June 30, 2019, the accrued loss provision for the two open loss jobs was $0.1 million and estimated remaining revenue for the jobs was $0.6 million. The remaining Belton area job is not in a loss position and contributed ($0.7) million and ($0.2) million gross profit during the three and six months ended June 30, 2019, respectively. At June 30, 2019, estimated remaining revenue for the remaining Belton area job was $10.7 million, with completion scheduled for 2019.

At June 30, 2019, we had approximately $50.2 million of unapproved contract modifications included in the aggregate transaction prices associated with the Belton area projects. Approximately $49.1 million of the contract modifications had been recognized as revenue on a cumulative catch-up basis through June 30, 2019.

Geographic area financial information

The majority of our revenue is derived from customers in the United States with approximately 5.0% generated from sources outside of the United States during the six months ended June 30, 2019, principally in Canada.

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. We define backlog as a combination of: (1) anticipated revenue from the uncompleted portions of existing contracts for which we have known revenue amounts for fixed-price and unit-price contracts (“Fixed Backlog”), and (2) the estimated revenue on MSA work 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 final revenue amount is difficult to estimate in advance. However, 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 reportable segment as of December 31, 2018 and June 30, 2019 and the changes in Fixed Backlog for the six months ended June 30, 2019 are as follows (in millions):

	Beginning Fixed						Ending Fixed				Revenue				Total Revenue
	Backlog at		Contract		Revenue		Backlog at				Recognized from				for Six Months
	December 31,		Additions to		Recognized from		June 30,				Non-Fixed				ended June 30,
Reportable Segment	2018		Fixed Backlog		Fixed Backlog		2019		00	00	Backlog Projects		00	00	2019
Power	$	245.3	$	359.2	$	224.7	$	379.8			$	92.9			$	317.6
Pipeline		672.5		341.5		230.0		784.0				42.0				272.0
Utilities		31.1		94.1		76.6		48.6				291.9				368.5
Transmission		21.5		48.0		41.2		28.3				212.6				253.8
Civil		505.6		300.0		231.6		574.0				8.0				239.6
Total	$	1,476.0	$	1,142.8	$	804.1	$	1,814.7			$	647.4			$	1,451.5

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

At June 30, 2019, our total Fixed Backlog was $1.81 billion, representing an increase of $338.7 million, or 22.9%, compared to $1.48 billion at December 31, 2018. 

MSA Backlog

The following table outlines historical MSA revenue for the past six quarters (in millions):

	Quarterly MSA Revenue
	2018		2019
First Quarter	$	146.4	$	292.9
Second Quarter	$	238.7	$	348.3
Third Quarter	$	390.4
Fourth Quarter	$	353.1

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

41

The following table shows our estimated MSA Backlog at June 30, 2019 by reportable segment (in millions):

	MSA Backlog
	at June 30,
Reportable Segment:	2019
Power	$	119.0
Pipeline		82.3
Utilities		733.8
Transmission		444.7
Civil		2.0
Total	$	1,381.8

Total Backlog

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

Reportable Segment:	June 30, 2018		September 30, 2018		December 31, 2018		March 31, 2019		June 30, 2019
Power	$	387.2	$	358.7	$	367.1	$	557.8	$	498.8
Pipeline		910.3		868.6		702.8		659.5		866.3
Utilities		683.4		698.0		789.3		802.3		782.4
Transmission		325.9		341.1		394.9		468.9		473.0
Civil		527.2		440.2		505.6		451.5		576.0
Total	$	2,834.0	$	2,706.6	$	2,759.7	$	2,940.0	$	3,196.5

We expect that during the next four quarters, we will recognize as revenue approximately 73% of the total backlog at June 30, 2019, comprised of backlog of approximately: 78% of the Power segment; 32% of the Pipeline segment; 100% of the Utilities segment; 100% of the Transmission segment; and 71% of the Civil segment.

Backlog should not be considered a comprehensive indicator of future revenue, as a percentage of our revenue is derived from projects that are not part of a backlog calculation. The backlog estimates include amounts from estimated MSA revenue, 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 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 revenue 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 revenue from projects completed under time and material 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. At June 30, 2019, there was $55.0 million of outstanding borrowings under the Revolving Credit Facility, commercial letters of credit outstanding were $41.4 million, and available borrowing capacity was $103.6 million. 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 $54.1 million at June 30, 2019, compared to $151.1 million at December 31, 2018. 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 settle our commitments and contingencies for at least the next twelve months. In evaluating our liquidity needs, we do not consider cash and cash equivalents held by our consolidated VIEs. These amounts, which

42

totaled $2.2 million and $3.1 million as of June 30, 2019 and December 31, 2018, respectively, were not available for general corporate purposes.

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 six months ended June 30, 2019, we spent approximately $56.9 million for capital expenditures, which included $38.2 million for construction equipment. The total of our depreciation, amortization and equipment sales was approximately $64.6 million. Capital expenditures for the remaining six months of 2019 are expected to total between $15.0 million and $20.0 million.

Cash Flows

Cash flows during the six months ended June 30, 2019 and 2018 are summarized as follows (in thousands):

	Six months ended
	June 30,
	2019		2018
Change in cash:
Net cash used in operating activities	$	(96,524)	$	(716)
Net cash used in investing activities		(35,711)		(151,326)
Net cash provided by financing activities		34,432		156,738
Effect of exchange rate changes		854		(185)
Net change in cash and cash equivalents	$	(96,949)	$	4,511

Operating Activities

The source of our cash flows from operating activities for the six months ended June 30, 2019 and 2018 were as follows (in thousands):

	Six months ended
	June 30,
	2019		2018		Change
Operating Activities:
Net income	$	20,760	$	18,407	$	2,353
Depreciation and amortization		43,392		35,175		8,217
Changes in assets and liabilities		(156,981)		(53,216)		(103,765)
Other		(3,695)		(1,082)		(2,613)
Net cash used in operating activities	$	(96,524)	$	(716)	$	(95,808)

Net cash used in operating activities for the six months ended June 30, 2019 was $96.5 million compared to $0.7 million for the six months ended June 30, 2018. The change year-over-year was primarily due to an unfavorable impact from the changes in assets and liabilities.

The significant components of the $157.0 million change in assets and liabilities for the six months ended June 30, 2019 are summarized as follows:

● Accounts receivable increased by $98.0 million from December 31, 2018, due primarily to an increase in revenue and a $58.9 million increase from the delay in payments from one of our utility customers while they go through bankruptcy proceedings. We continue to maintain an excellent collection history, and we have certain lien rights that provide additional security for collections, if necessary;

● Contract assets increased by $51.0 million from December 31, 2018, primarily due to an increase in unbilled revenue;

● Accounts payable and accrued liabilities decreased by $17.9 million from December 31, 2018, due to the timing of payments.

43

Investing activities

For the six months ended June 30, 2019, we used $35.7 million in cash from investing activities compared to $151.3 million for the six months ended June 30, 2018.

During the six months ended June 30, 2019, we purchased property and equipment for $56.9 million in cash compared to $46.1 million during the same period in the prior year.  We believe the ownership of equipment is generally preferable to renting equipment on a project-by-project basis, as ownership helps to ensure the equipment is available for our projects when needed. In addition, ownership has historically resulted in lower overall equipment costs.

During the six months ended June 30, 2018, we used $111.0 million of cash for the acquisition of Willbros.

In connection with the acquisition of Willbros, we agreed to provide, at our discretion, up to $20.0 million in secured bridge financing to support Willbros’ working capital needs through the closing date. In March 2018 and May 2018, we provided $10.0 million and $5.0 million, respectively, in secured bridge financing to Willbros. The $15.0 million was repaid in its entirety on June 1, 2018.

Financing activities

Financing activities provided cash of $34.4 million for the six months ended June 30, 2019, which was primarily due to the following:

● Net borrowings under our revolving credit facility of $55.0 million;

● Proceeds from the issuance of debt secured by our equipment of $23.1 million;

● Repayment of long-term debt of $34.3 million;

● Dividend payments to our stockholders of $6.1 million; and

● Cash distributions to non-controlling interest holders of $3.5 million.

Financing activities provided cash of $156.7 million for the six months ended June 30, 2018, which was primarily due to the following:

● Borrowings under our revolving credit facility of $170.0 million;

● Proceeds from the issuances of debt secured by our equipment of $19.5 million

● Repayment of long-term debt of $28.0 million; and

● Dividend payments to our stockholders of $6.2 million.

Credit Agreements

For a description of our credit agreements, see Note 9 — “Credit Arrangements” in Item 1, Financial Statements of this Second Quarter 2019 Report.

Common stock

For a discussion of items affecting our common stock, please see Note 15 — “Stockholders’ Equity” in Item 1, Financial Statements of this Second Quarter 2019 Report.

Off-balance sheet transactions

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

● At June 30, 2019, we had letters of credit outstanding of $41.6 million under the terms of our credit agreements. These letters of credit are used by our insurance carriers 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

44

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 Second Quarter 2019 Report, we do not believe that it is likely that any material claims will be made under a letter of credit;

● In the ordinary course of our business, we may be required by our customers to post surety bid or completion bonds in connection with services that we provide. At June 30, 2019, we had $598.7 million in outstanding bonds.  As of the date of this Second Quarter 2019 Report, we do not anticipate that we would have to fund material claims under our surety arrangements;

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

● We enter into employment agreements with certain employees which provide for compensation and benefits under certain circumstances and which may contain a change of control clause. We may be obligated to make payments under the terms of these agreements; and

● From time to time, we make other guarantees, such as guaranteeing the obligations of our subsidiaries.

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. To date, our operations have not been materially impacted by the effects of increases in prices.

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.

Interest rate risk. Our revolving credit facility and term loan bear interest at a variable rate and exposes us to interest rate risk. From time to time, we may use certain derivative instruments to hedge our exposure to variable interest rates. As of June 30, 2019, $156.8 million of our variable rate debt outstanding was economically hedged. Based on our variable rate debt outstanding as of June 30, 2019, a 1.0% increase or decrease in interest rates would change annual interest expense by approximately $1.1 million.

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

45

Item 4. Controls and Procedures

Disclosure Controls and Procedures

As of June 30, 2019, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of our “disclosure controls and procedures”, as such term is defined under Exchange Act Rules 13a-15(e) and 15d-15(e).

Based on this evaluation, our CEO and CFO concluded that, at June 30, 2019, 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. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their stated objectives.

Changes in Internal Control Over Financial Reporting

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 during the six months ended June 30, 2019.

Part II. Other Information

Item 1. Legal Proceedings

The information required for this item is provided in Note 17 — “Commitments and Contingencies”, included in the unaudited notes to our condensed consolidated financial statements included under Part I of this Form 10-Q, which is incorporated herein by reference.

Item 1A. Risk Factors.

In addition to the information set forth in this Report, you should carefully consider the factors discussed in the section entitled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2018, which to our knowledge have not materially changed. Those risks, which could materially affect our business, financial condition or future results, are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Exhibit 10.1

AGREEMENT FOR SERVICES 

This Agreement for Services (“Agreement”) is made and entered into as of July 1, 2019 between Primoris Services Corporation, a Delaware corporation (“PRIM”), and Brian Pratt, an individual (hereinafter referred to as “Director/Advisor”) and supersedes, in its entirety, the agreement entered into between PRIM and Director/Advisor dated August 1, 2015.  PRIM and Director/Advisor may be individually referred to as “Party” or collectively referred to herein as the “Parties.”

A.  INTRODUCTION

WHEREAS, PRIM is engaged in the business of providing, among other services, site development, heavy civil construction, water and wastewater construction, fabrication, infrastructure construction, including highways and bridges, oil and gas pipeline construction and replacement, directional drilling, construction of industrial facilities, equipment installation, storage facilities, process piping, engineering, project management, inspection services, structural steel and maintenance services (the “Business”).

(i)In the event  this Agreement terminates before the end of the term,  A)  By PRIM, with Cause (including removal in accordance with the bylaws and corporate charters of PRIM),  or B)  as a result of death, disability or voluntary termination by Director/Advisor, and regardless of whether such termination relates  to the services provided herein as a Director of the Board of Directors, or the services provided herein as Strategic Advisor, or both, PRIM shall pay, and Director/Advisor shall only be entitled to, all of the compensation to which Director/Advisor has been paid through the date of such termination, including any accelerated payments that may have been paid to Director/Advisor.

(ii)In the event this Agreement terminates before the end of the term by PRIM, without Cause, and such termination relates to the services provided herein as a Director of the Board of Directors, PRIM shall pay, and Director/Advisor shall be entitled to, all of the compensation to which Director/Advisor

2

has been paid through the date of such termination, including any accelerated payments that may have been paid to Director/Advisor.

(iii)In the event this Agreement terminates before the end of the term by PRIM, without Cause, and such termination relates to the services provided herein as Strategic Advisor, PRIM shall pay, and Director/Advisor shall be entitled to, all of the compensation to which Director/Advisor would have been paid through the entire term of this Agreement.

Director/Advisor hereby irrevocably assigns to PRIM, in each case without additional consideration, all right, title and interest throughout the world in and to all such results and proceeds of the services performed under this Agreement, including all Intellectual Property Rights therein.

b.Director/Advisor shall make full and prompt disclosure to PRIM of any inventions or processes, as such terms are defined in 35 U.S.C. § 100 (the “Patent Act”), made or conceived by Director/Advisor alone or with others during the Term relating to the Business or in connection with Director/Advisor’s performance of services pursuant to this Agreement,  whether or not such inventions or processes are patentable or protected as trade secrets and whether or not such inventions or processes are made or conceived during normal working hours or on the premises of PRIM.

In the event PRIM is unable, after reasonable effort, to obtain Director/Advisor’s signature on any such documents, Director/Advisor hereby irrevocably designates and appoints PRIM as Director/Advisor’s agent and attorney-in-fact, to act for and on Director/Advisor’s behalf solely to execute and file any such application or other document and do all other lawfully permitted acts to further the prosecution and issuance of patents, copyrights or other intellectual property protected related to any deliverables delivered by Director/Advisor to PRIM with the same legal force and effect as if Director/Advisor had executed them.

Director/Advisor acknowledges that the services to be rendered by Director/Advisor pursuant to this Agreement are unique and, accordingly, Director/Advisor may not assign this Agreement or assign or delegate any of Director/Advisor’s rights or duties or obligations under this Agreement, without the prior written consent of PRIM, which consent may be withheld in PRIM’s sole and absolute discretion.

5

b.  This Agreement and the rights and obligations hereunder may not be assigned or delegated by PRIM without the prior written consent of Director/Advisor; provided, however, that PRIM may assign this Agreement and assign and/or delegate any of its rights or obligations this Agreement without the prior consent of Director/Advisor to: (i) any one or more of its Affiliates, or (ii) a purchaser of or successor to all or substantially all of the business, assets, stock of PRIM, whether by asset sale, stock sale, merger or other transaction, regardless of form.

14.Severability.  If any provision contained herein is held to be invalid or unenforceable by a court of competent jurisdiction, such provision will be severed herefrom and such invalidity or unenforceability will not affect any other provision of this Agreement, the balance of which will remain in and have its intended full force and effect; provided, however, if such invalid or unenforceable provision may be modified so as to be valid and enforceable as a matter of law, such provision will be deemed to have been modified so as to be valid and enforceable to the maximum extent permitted by law. 

15.Governing Law.  This Agreement will be governed, construed and interpreted in accordance with the laws and decisions of the State of Texas, without regard to conflict of law principles that would require the law of another state or jurisdiction to be applied.

16.Dispute Resolution. Any controversy or claim arising out of or relating to this Agreement or the breach thereof (a “Dispute”) shall be decided by mandatory, final and binding arbitration in accordance with the Comprehensive Arbitration Rules and Procedures of JAMS, as supplemented below, with exclusive venue for such arbitration in Dallas, Texas.

a.Independent Nature of Arbitrator.  The arbitrator shall be independent of the Parties and under no circumstance shall any mediator or arbitrator have any connection to or relationship with any of the Parties, or their respective principals or employees.

b.Arbitration Proceeding.

(i)If any Party desires to arbitrate any Dispute, such Party shall notify the other Party of the Dispute desired to be arbitrated, including a brief statement of the matter in controversy.  If the Parties are not able to resolve the Dispute within five (5) days after the Party notifies the other Party of its desire to arbitrate (an “Arbitration Notice”) then, within five (5) days immediately after the expiration of the aforesaid five (5) day period, the Parties shall attempt to agree upon an independent arbitrator.  Unless the Parties can agree in writing on a single arbitrator within five (5) days, then, within five (5) days after thereafter, each Party shall notify the other in writing of the name of the independent arbitrator chosen by them to identify the independent arbitrator.  If either Party fails to timely give the other notice of such appointment, then the Party who timely gave such notice shall be

6

entitled to require that its arbitrator act as the sole arbitrator hereunder.  If an arbitrator is timely appointed by each of the Parties, the two named arbitrators shall select the independent arbitrator within five (5) days after they have both been appointed, and they shall promptly notify the Parties thereof.  Each Party shall promptly notify the other Party and the Party-selected arbitrators in writing if the independent arbitrator has any relationship to or affiliation with such Party (a “Notice of Relationship”) in which event another arbitrator shall be selected within five (5) days after receipt of such Notice of Relationship by the Party-selected arbitrators.  If the two initially appointed arbitrators cannot agree on an independent arbitrator, then any Party may request that JAMS select the independent arbitrator.

(ii)Arbitration demanded hereunder by any Party shall be final and binding on the Parties and may not be appealed.

(iii)The Parties agree that the independent arbitrator may render and the Parties shall abide by any interim ruling that the independent arbitrator deems necessary or prudent regarding discovery, summary proceedings, or other pre-arbitration matters.

(iv) The Parties hereby submit to the in personam jurisdiction of the state and federal courts located in Dallas County, Texas, and agree that any such court may enter all such orders as may be necessary or appropriate to enforce the provisions hereof and/or to confirm any pre-arbitration ruling or decision or any award rendered by the independent arbitrator.  Any court of law of Texas or the United States of America shall enforce the decision of the independent arbitrator (or single arbitrator, as applicable) in its entirety and only in its entirety; provided, however, that if a court for any reason refuses to enforce any equitable remedies ordered by the independent arbitrator, such refusal shall not affect any damage or attorney fee award made by the independent arbitrator.

(v)Any costs or other expenses, including reasonable attorneys’ fees and costs incurred by the successful Party, arising out of or occurring because of the arbitration proceedings may be assessed against the unsuccessful Party, borne equally, or assessed in any manner within the sound discretion of the independent arbitrator and shall be included as part of any order or decision rendered by the independent arbitrator.  The independent arbitrator may also order any Party who is ordered to pay any other Party’s attorneys’ fees and costs to pay interest on such award at a rate not to exceed ten percent (10%) per annum from the date of the award until paid.  As an initial matter (and until ordered differently by the independent arbitrator in connection with an award), the Parties shall each pay the fees, costs and expenses charged by the arbitrator chosen by it, and, in advance, one-half (1/2) of the fees, costs and expenses charged by the independent arbitrator.

(vi)Third parties dealing with any Party shall be entitled to fully rely on any written arbitration order or decision with regard to the matters addressed therein, whether or not such arbitration order or decision has been confirmed or adopted by a court, or incorporated in any order of any court. 

c.Power and Authority of Arbitrator.  The arbitrator shall not have any power to alter, amend, modify or change any of the terms of this Agreement nor to grant any remedy which is either prohibited by the terms of this Agreement, or not available in a court of law.

d.Attorneys’ Fees.  If a Party to this Agreement shall bring any action, suit, counterclaim, appeal, arbitration, or mediation for any relief against the other Party, declaratory or otherwise, to enforce the terms hereof or to declare rights hereunder (“Action”), the non-prevailing Party in such Action shall pay to the prevailing Party in such Action a reasonable sum for the prevailing Party’s attorneys’ fees and expenses (at the prevailing Party’s attorneys’ then-current rates, as increased from time to time by the giving of advance written notice by such counsel to such Party) incurred in prosecuting or defending such Action and/or enforcing any judgment, order, ruling or award (“Decision”) granted therein, all of which shall be deemed to have accrued from the commencement of such Action, and shall be paid whether or not such Action is prosecuted to a Decision.  Any Decision entered into in such Action shall contain a specific provision providing for the recovery of attorneys’ fees and expenses incurred in enforcing such Decision.  The court or arbitrator may fix the amount of reasonable attorneys’ fees and expenses upon the request of any Party.  For purposes of this Section 16, attorneys’ fees shall include, without limitation, fees incurred in connection with (i) post-judgment motions and collection actions, (ii) contempt proceedings, (iii) garnishment, levy and debtor and third party examination, (iv) discovery, and (v) bankruptcy litigation.

7

17.WAIVER OF JURY TRIAL.  THE PARTIES HERETO CONSENT TO TRIAL WITHOUT A JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY ANY PARTY HERETO AGAINST THE OTHER OR THEIR SUCCESSORS IN RESPECT OF ANY MATTER ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT, REGARDLESS OF THE FORM OF ANY ACTION OR PROCEEDING.

18.Construction; Miscellaneous.

a.The numbers, headings, titles or designations of the various Sections are not a part of this Agreement, but are for convenience and reference only, and do not and will not be used to define, limit or construe the contents of the Sections.

b.This Agreement constitutes the entire agreement between PRIM and Director/Advisor with respect to the subject matter hereof, and supersedes any and all prior and contemporaneous oral or written agreements between Director/Advisor and PRIM; provided, however, that Director/Advisor acknowledges and agrees that the non-competition and non-solicitation provisions set forth in Section 4 shall not affect or supersede any non-competition, non-solicitation or other similar restrictive covenants or provisions contained in any other agreement entered into by and between Director/Advisor and PRIM and/or any of its Affiliates, including any Non-Competition Agreement entered into in connection with the sale of the assets of the Seller to PRIM or one of its Affiliates.

c.This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument.

d.This Agreement may not be amended, changed, modified discharged or terminated except by a writing signed by PRIM and Director/Advisor.

e.The recitals set forth at the beginning of this Agreement are hereby incorporated in full into and made a part of this Agreement by this reference as if fully set forth in the body of this Agreement.

19.Survival.  The rights and obligations of the Parties set forth in Sections 5 - 8 and 10 - 19 shall indefinitely survive the expiration or any earlier termination of this Agreement. The obligations of PRIM set forth in Section 3 shall survive until fully performed by PRIM or otherwise discharged. The obligations of the Parties set forth in Section 4 and Section 9 shall survive for the periods of time set forth in each such Section.

IN WITNESS WHEREOF, PRIM and Director/Advisor have executed this Agreement as of the date first written above.

Nature of Business

Note 1—Nature of Business

Organization and operations — Primoris Services Corporation is a holding company of various construction and product engineering subsidiaries. We are incorporated in the State of Delaware, and our corporate headquarters are located at 2300 N. Field Street, Suite 1900, Dallas, Texas 75201. 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.

Reportable Segments — We segregate our business into five reportable segments: the Power, Industrial and Engineering (“Power”) segment, the Pipeline and Underground (“Pipeline”) segment, the Utilities and Distribution (“Utilities”) segment, the Transmission and Distribution (“Transmission”) segment, and the Civil segment. See Note 18 – “Reportable Segments” for a brief description of the reportable segments and their operations.

The classification of revenue and gross profit for segment reporting purposes can at times require judgment on the part of management. Our segments may perform services across industries or perform joint services for customers in multiple industries. To determine reportable segment gross profit, certain allocations, including allocations of shared and indirect costs, such as facility costs, equipment costs and indirect operating expenses were made.

Acquisition of Willbros Group, Inc. — On June 1, 2018, we completed our acquisition of Willbros Group, Inc. (“Willbros”) for approximately $110.6 million, net of cash and restricted cash acquired. Willbros is a specialty energy infrastructure contractor serving the oil and gas and power industries through its utility transmission and distribution, oil and gas, and Canadian operations, which principally provides unit-price maintenance services in existing operating facilities and executes industrial and power projects. The utility transmission and distribution operations formed the Transmission segment, the oil and gas operations are included in the Pipeline segment, and the Canadian operations are included in the Power segment. See Note 5— “Business Combinations”.

Joint Ventures — We own a 50% interest in the Carlsbad Power Constructors joint venture (“Carlsbad”), which engineered and constructed a gas-fired power generation facility located in Southern California, and its operations are included as part of the Power segment. As a result of determining that we are the primary beneficiary of the variable interest entity (“VIE”), the results of the Carlsbad joint venture are consolidated in our financial statements. The project was substantially complete as of December 31, 2018 and the warranty period expires in December 2020.

We owned a 50% interest in the “ARB Inc. & B&M Engineering Co.” joint venture (“Wilmington”), which engineered and constructed a gas-fired power generation facility in Southern California, and its operations were included as part of the Power segment. As a result of determining that we were the primary beneficiary of the VIE, the results of the Wilmington joint venture were consolidated in our financial statements. The project has been completed, the project warranty period expired, and dissolution of the joint venture was completed in the first quarter of 2019.

Financial information for the joint ventures is presented in Note 11 – “Noncontrolling Interests”.

Note 2—Basis of Presentation

Interim condensed consolidated financial statements — The interim condensed consolidated financial statements for the three and six month periods ended June 30, 2019 and 2018 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 our Annual Report on Form 10-K, filed on February 28, 2019, which contains our audited consolidated financial statements for the year ended December 31, 2018, have been omitted.

This Second Quarter 2019 Report on Form 10-Q should be read in conjunction with our 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. 

Customer concentration — We operate in multiple industry segments encompassing the construction of commercial, industrial and public works infrastructure assets primarily throughout the United States. Typically, the top ten customers in any one calendar year generate revenue that is approximately 50% of total revenue; however, the group that comprises the top ten customers varies from year to year.

During the three and six months ended June 30, 2019, revenue generated by the top ten customers was approximately $372.4 million and $696.5 million, respectively, which represented 47.1% and 48.0%, respectively of total revenue during the period. During the three and six months ended June 30, 2019, a Midwest utility customer represented 8.0% and 6.7% of total revenue, respectively, and an electric utility customer represented 7.6% and 8.3% of total revenue, respectively.

During the three and six months ended June 30, 2018, revenue generated by the top ten customers was approximately $322.6 million and $581.6 million, respectively, which represented 50.4% and 49.7%, respectively, of total revenue during the period. During the three and six months ended June 30, 2018, a state department of transportation customer represented 9.4% and 9.3% of total revenue, respectively, and a California utility customer represented 8.7% and 9.0% of total revenue, respectively.

At June 30, 2019, approximately 8.7% of our accounts receivable was due from one customer, and that customer provided 8.3% of our revenue for the six months ended June 30, 2019.

On January 29, 2019, one of our utility customers filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. As of June 30, 2019, the utility customer comprised approximately 14.0% of our total accounts receivable. In addition to accounts receivable, there is approximately $15.8 million in unbilled revenue, net as of June 30, 2019. For the three and six months ended June 30, 2019, the customer accounted for approximately 5.9% and 5.7%, respectively, of our total revenue. A portion of the accounts receivable balance is past due, but we do not believe a reserve for the accounts receivable and unbilled revenue is appropriate at this time. However, we will closely monitor our current and future potential exposure.

Note 3—Recent Accounting Pronouncements

Recently adopted accounting pronouncements

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, with several clarifying updates. ASU 2016-02 requires 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 also requires disclosures that provide qualitative and quantitative information for the lease assets and liabilities recorded in the financial statements. The standard is effective for fiscal years beginning after December 15, 2018, and requires a modified retrospective transition method where a company applies the new lease standard at (i) the beginning of the earliest period presented in the financial statements, or (ii) the adoption date and recognizes a cumulative effect adjustment to the opening balance of retained earnings. We adopted the new standard as of January 1, 2019 using the modified retrospective transition method and elected to apply the new lease standard at the adoption date. See Note 16 — “Leases” for further details.

In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment". ASU 2017-04 removes the second step of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We adopted the standard on January 1, 2019, and it did not have an impact on our financial position, results of operations, or cash flows.

Recently issued accounting pronouncements not yet adopted

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments”, which introduced an expected credit loss methodology for the measurement and recognition of credit losses on most financial assets, including trade accounts receivables. The expected credit loss methodology under ASU 2016-13 is based on historical experience, current conditions and reasonable and supportable forecasts, and replaces the probable/incurred loss model for measuring and recognizing expected losses under current GAAP. The ASU also requires disclosure of information regarding how a company

developed its allowance, including changes in the factors that influenced management’s estimate of expected credit losses and the reasons for those changes. The ASU and its related clarifying updates are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. Based on our historical experience, we do not currently expect this ASU to have a material impact on our estimate of the allowance for uncollectable accounts.

In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement”, which eliminates certain disclosure requirements for recurring and nonrecurring fair value measurements. The ASU eliminates such disclosures as the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, and adds new disclosure requirements for Level 3 measurements. This ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for any eliminated or modified disclosures. We do not expect the adoption of this ASU to have a material impact on our disclosures.

Fair Value Measurements

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, our financial assets and liabilities that are required to be measured at fair value at June 30, 2019 and December 31, 2018 (in thousands):

	Fair Value Measurements at Reporting Date
			Significant
	Quoted Prices		Other		Significant
	in Active Markets		Observable		Unobservable
	for Identical Assets		Inputs		Inputs
	(Level 1)		(Level 2)		(Level 3)
Assets as of June 30, 2019:
Cash and cash equivalents	$	54,114	$	—	$	—
Contingent consideration	$	—	$	—	$	938
Liabilities as of June 30, 2019:
Interest rate swap	$	—	$	7,023	$	—
Assets as of December 31, 2018:
Cash and cash equivalents	$	151,063	$	—	$	—
Liabilities as of December 31, 2018:
Interest rate swap	$	—	$	2,829	$	—

Other financial instruments 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 our long-term debt approximates fair value based on comparison with current prevailing market rates for loans of similar risks and maturities.

In the second quarter of 2019, we sold certain assets that included an earnout of $2.0 million, contingent upon the buyer meeting certain performance targets. The estimated fair value of the contingent consideration on the sale date was approximately $0.9 million. We measured the fair value of the contingent consideration using the income approach, which discounts the future cash payments expected upon meeting the performance targets to present value. The fair

value of the contingent consideration was impacted by two unobservable inputs, management’s estimate of the probability of meeting the performance target and the estimated discount rate (a rate that approximates our cost of capital). Significant changes in either of those inputs in isolation would result in a different fair value measurement.

The interest rate swap is measured at fair value using the income approach, which discounts the future net cash settlements expected under the derivative contracts to a present value. These valuations primarily utilize indirectly observable inputs, including contractual terms, interest rates and yield curves observable at commonly quoted intervals. See Note 10 – “Derivative Instruments” for additional information.

2018 Acquisition

Acquisition of Willbros Group, Inc.

On June 1, 2018, we acquired all of the outstanding common stock of Willbros, a specialty energy infrastructure contractor serving the oil and gas and power industries for approximately $110.6 million, net of cash and restricted cash acquired. The total purchase price was funded through a combination of existing cash balances and borrowings under our revolving credit facility.

During the second quarter of 2019, we finalized the estimate of fair values of the assets acquired and liabilities assumed of Willbros. The tables below represent the purchase consideration and estimated fair values of the assets acquired and liabilities assumed. Significant changes since our initial estimates reported in the second quarter of 2018 primarily relate to fair value adjustments to our acquired contracts, which resulted in an increase to contract liabilities of $23.7 million. In addition, fair value adjustments to our acquired lease obligations and insurance liabilities reduced our liabilities assumed by approximately $11.9 million and $6.0 million, respectively, and fair value adjustments to our acquired intangible assets decreased our assets acquired by $6.8 million. As a result of these and other adjustments to the initial estimated fair values of the assets acquired and liabilities assumed, goodwill increased by approximately $18.0 million since the second quarter of 2018. Adjustments recorded to the estimated fair values of the assets acquired and liabilities assumed are recognized in the period in which the adjustments are determined and calculated as if the accounting had been completed as of the acquisition date.

We separated the operations of Willbros among two of our existing segments, and created a new segment for the utility transmission and distribution operations called the Transmission segment. The oil and gas operations are included in the Pipeline segment, and the Canadian operations are included in the Power segment. Goodwill associated with the Willbros acquisition principally consists of expected benefits from the expansion of our services into electric utility-focused offerings and the expansion of our geographic presence. Goodwill also includes the value of the assembled workforce. We allocated $59.0 million of goodwill to the Transmission segment, $1.8 million to the Power segment, and $0.9 million to the Pipeline segment. Based on the current tax treatment, goodwill is not expected to be deductible for income tax purposes.

As part of the Willbros acquisition, we acquired approximately $40.2 million of restricted cash that was pledged by Willbros to secure letters of credit. Subsequent to the acquisition, we issued new letters of credit under our Credit Facility to replace the Willbros letters of credit secured by the restricted cash. As of June 30, 2019, substantially all of the restricted cash had been released.

For the three and six months ended June 30, 2019, Willbros contributed revenue of $182.3 million and $340.0 million, respectively, and gross profit of $14.4 million and $22.0 million, respectively . For the period June 1, 2018, the acquisition date, to June 30, 2018, Willbros contributed revenue of $61.0 million and gross profit of $6.8 million.

Acquisition related costs were $7.7 million and $9.3 million for the three and six months ended June 30, 2018, respectively, related to the acquisition of Willbros and are included in “Merger and related costs” on the Condensed Consolidated Statements of Income. Such costs primarily consisted of severance and retention bonus costs for certain employees of Willbros and professional fees paid to advisors.

Supplemental Unaudited Pro Forma Information for the three and six months ended June 30, 2018

The following pro forma information for the three and six months ended June 30, 2018 presents our results of operations as if the acquisitions of Willbros had occurred at the beginning of 2018. The supplemental pro forma information has been adjusted to include:

● the pro forma impact of amortization of intangible assets and depreciation of property, plant and equipment;

● the pro forma impact of nonrecurring merger and related costs directly attributable to the acquisition;

● the pro forma impact of interest expense relating to the acquisition; and

● the pro forma tax effect of both income before income taxes, and the pro forma adjustments, calculated using a tax rate of 28.0% for the three and six months ended June 30, 2018.

The pro forma results are presented for illustrative purposes only and are not necessarily indicative of, or intended to represent, the results that would have been achieved had the Willbros acquisition been completed on January 1, 2018. For example, the pro forma results do not reflect any operating efficiencies and associated cost savings that we might have achieved with respect to the acquisition.

Revenue

Note 6—Revenue

We generate revenue under a range of contracting types, including fixed-price, unit-price, time and material, and cost reimbursable plus fee contracts. A substantial portion of our revenue is derived from contracts that are fixed-price or unit-price and is recognized over time as work is completed because of the continuous transfer of control to the customer (typically using an input measure such as costs incurred to date relative to total estimated costs at completion to measure progress). For time and material and cost reimbursable plus fee contracts, revenue is recognized primarily on an input basis, based on contract costs incurred as defined within the respective contracts. Costs to obtain contracts are generally not significant and are expensed in the period incurred.

We evaluate whether two or more contracts should be combined and accounted for as one single performance obligation and whether a single contract should be accounted for as more than one performance obligation. ASC 606 defines a performance obligation as a contractual promise to transfer a distinct good or service to a customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Our evaluation requires significant judgment and the decision to combine a group of contracts or separate a contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. The majority of our contracts have a single performance obligation, as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contract and, therefore, is not distinct. However, occasionally we have contracts with multiple performance obligations. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using the observable standalone selling price, if available, or alternatively our best estimate of the standalone selling price of each distinct

performance obligation in the contract. The primary method used to estimate standalone selling price is the expected cost plus a margin approach for each performance obligation.

As of June 30, 2019, we had $1.93 billion of remaining performance obligations. We expect to recognize approximately 55% of our remaining performance obligations as revenue during the next four quarters and substantially all of the remaining balance by the second quarter of 2021.

Accounting for long-term contracts involves the use of various techniques to estimate total transaction price and costs. For long-term contracts, transaction price, estimated cost at completion and total costs incurred to date are used to calculate revenue 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 revenue 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 nature of our contracts gives rise to several types of variable consideration, including contract modifications (change orders and claims), liquidated damages, volume discounts, performance bonuses, incentive fees, and other terms that can either increase or decrease the transaction price. We estimate variable consideration as the most likely amount to which we expect to be entitled. We include estimated amounts in the transaction price to the extent we believe we have an enforceable right, and it is probable that a significant reversal of cumulative revenue recognized will not occur. Our estimates of variable consideration and the determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us at this time.

Contract modifications result from changes in contract specifications or requirements. We consider unapproved change orders to be contract modifications for which customers have not agreed to both scope and price. We consider claims to be contract modifications for which we seek, 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. Claims can also be caused by non-customer-caused changes, such as rain or other weather delays. Costs associated with contract modifications are included in the estimated costs to complete the contracts and are treated as project costs when incurred. In most instances, contract modifications are for goods or services that are not distinct, and, therefore, are accounted for as part of the existing contract. The effect of a contract modification on the transaction price, and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis. In some cases, settlement of contract modifications may not occur until after completion of work under the contract.

As a significant change in one or more of these estimates could affect the profitability of our contracts, we review and update our contract-related estimates regularly. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the cumulative impact of the profit adjustment is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance are recognized using the adjusted estimate. In the three and six months ended June 30, 2019, revenue recognized from performance obligations satisfied in previous periods was $4.2 million and $10.7 million, respectively. If at any time the estimate of contract profitability indicates an anticipated loss on a contract, the projected loss is recognized in full, including any previously recognized profit, in the period it is identified and recognized as an “accrued loss provision” which is included in “Contract liabilities” on the Condensed Consolidated Balance Sheets. For contract revenue recognized over time, the accrued loss provision is adjusted so that the gross profit for the contract remains zero in future periods.

At June 30, 2019, we had approximately $84.1 million of unapproved contract modifications included in the aggregate transaction prices. These contract modifications were in the process of being negotiated in the normal course of business. Approximately $79.3 million of the contract modifications had been recognized as revenue on a cumulative catch-up basis through June 30, 2019.

In all forms of contracts, we estimate the collectability of contract amounts at the same time that we estimate project costs. If we anticipate that there may be issues associated with the collectability of the full amount calculated as

the transaction price, we 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.

The timing of when we bill our customers is generally dependent upon agreed-upon contractual terms, milestone billings based on the completion of certain phases of the work, or when services are provided. Sometimes, billing occurs subsequent to revenue recognition, resulting in unbilled revenue, which is a contract asset. Also, we sometimes receive advances or deposits from our customers before revenue is recognized, resulting in deferred revenue, which is a contract liability.

The caption “Contract assets” in the Condensed Consolidated Balance Sheets represents the following:

● unbilled revenue, which arise when revenue has been recorded but the amount will not be billed until a later date;

● retainage amounts for the portion of the contract price earned by us for work performed, but held for payment by the customer as a form of security until we reach certain construction milestones; and

● contract materials for certain job specific materials not yet installed, which are valued using the specific identification method relating the cost incurred to a specific project.

Contract assets consist of the following (in thousands):

	June 30,		December 31,
	2019		2018
Unbilled revenue	$	311,915	$	249,577

Contract materials (not yet installed)		18,422		25,715
	$	415,142	$	364,245

Contract assets increased by $50.9 million compared to December 31, 2018 due primarily to higher unbilled revenue, partially offset by a reduction in contract materials net yet installed.

The caption “Contract liabilities” in the Condensed Consolidated Balance Sheets represents deferred revenue on billings in excess of contract revenue recognized to date, and the accrued loss provision.

Contract liabilities consist of the following (in thousands):

	June 30,		December 31,
	2019		2018
Deferred revenue	$	192,772	$	182,232
Accrued loss provision		5,013		7,307
	$	197,785	$	189,539

Contract liabilities increased by $8.2 million compared to December 31, 2018 primarily due to an increase in deferred revenue, partially offset by a reduction in the accrued loss provision.

Revenue recognized for the six months ended June 30, 2019, that was included in the contract liability balance at December 31, 2018 was approximately $135.1 million.

Each of these contract types has a different risk profile. Typically, we assume more risk with fixed-price contracts. Unforeseen events and circumstances can alter the estimate of the costs and potential profit associated with a particular fixed-price contract. However, these types of contracts offer additional profits when we complete the work for less cost than originally estimated. Unit-price and cost reimbursable contracts generally subject us to lower risk. Accordingly, the associated fees are usually lower than fees earned on fixed-price contracts. Under these contracts, our profit may vary if actual costs vary significantly from the negotiated rates.

Credit Agreement

Our credit agreement consists of a $220.0 million term loan and a $200.0 million revolving credit facility (“Revolving Credit Facility”), whereby the lenders agreed to make loans on a revolving basis from time to time and to issue letters of credit for up to the $200.0 million committed amount. The credit agreement also includes an accordion feature that would allow us to increase the borrowing capacity thereunder by $75.0 million, subject to obtaining additional or increased lender commitments. The maturity date of the credit agreement is July 9, 2023. At June 30, 2019, there was $55.0 million of outstanding borrowings under the Revolving Credit Facility, commercial letters of credit outstanding were $41.4 million, and available borrowing capacity was $103.6 million.

The credit agreement contains various restrictive and financial covenants including, among others, a senior debt/EBITDA ratio and debt service coverage requirements. In addition, the credit agreement includes restrictions on investments, change of control provisions and provisions in the event we dispose of more than 20% of our total assets. We were in compliance with the covenants for the Credit Agreement at June 30, 2019.

Canadian Credit Facility

We have a demand credit facility for $4.0 million in Canadian dollars with a Canadian bank for purposes of issuing commercial letters of credit in Canada.  At June 30, 2019, commercial letters of credit outstanding were $0.2 in Canadian dollars, and the available borrowing capacity was $3.8 million in Canadian dollars.  The credit facility contains a working capital restrictive covenant for OnQuest Canada, ULC, our wholly owned subsidiary.  At June 30, 2019, OnQuest Canada, ULC was in compliance with the covenant.

Derivative Instruments

Note 10 — Derivative Instruments

We are exposed to certain market risks related to changes in interest rates. To monitor and manage these market risks, we have established risk management policies and procedures. We do not enter into derivative instruments for any purpose other than hedging interest rate risk. None of our derivative instruments are used for trading purposes.

Interest Rate Risk. We are exposed to variable interest rate risk as a result of variable-rate borrowings under our Credit Agreement. To manage fluctuations in cash flows resulting from changes in interest rates on a portion of our variable-rate debt, we entered into an interest rate swap agreement on September 13, 2018 with an initial notional amount of $165.0 million, or 75% of the debt outstanding under our Term Loan, which was not designated as a hedge for accounting purposes. The notional amount of the swap will be adjusted down each quarter by 75% of the required principal payments made on the Term Loan. The swap effectively changes the variable-rate cash flow exposure on the debt obligations to fixed rates. The fair value of outstanding interest rate swap derivatives can vary significantly from period to period depending on the total notional amount of swap derivatives outstanding and fluctuations in market

interest rates compared to the interest rates fixed by the swaps. As of June 30, 2019, and December 31, 2018, our outstanding interest rate swap agreement contained a notional amount of $156.8 million and $160.9 million, respectively, with a maturity date of July 10, 2023.

Credit Risk. By using derivative instruments to economically hedge exposures to changes in interest rates, we are exposed to counterparty credit risk. Credit risk is the failure of a counterparty to perform under the terms of a derivative contract. When the fair value of a derivative contract is positive, the counterparty owes us, which creates credit risk for us. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, we do not possess credit risk. We minimize the credit risk in derivative instruments by entering into transactions with high quality counterparties. We have entered into netting agreements, including International Swap Dealers Association (“ISDA”) Agreements, which allow for netting of contract receivables and payables in the event of default by either party.

The following table summarizes the fair value of our derivative contracts included in the Condensed Consolidated Balance Sheets (in thousands):

Noncontrolling Interests

Note 11 — Noncontrolling Interests

We own a 50% interest in the Carlsbad joint venture and we owned a 50% interest in the Wilmington joint venture, each of which operates in the Power segment. Both joint ventures have been determined to be a VIE and we were determined to be the primary beneficiary as a result of our significant influence over the joint venture operations.

Each joint venture is a partnership, and consequently, only the tax effect of our share of the income was recognized by us. The net assets of the joint ventures are restricted for use by the specific project and are not available for our general operations.

Carlsbad Joint Venture

The Carlsbad joint venture’s operating activities began in 2015 and are included in our Condensed Consolidated Statements of Income as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,

Net income attributable to noncontrolling interests	$	37	$	2,330	$	1,026	$	5,444

The Carlsbad joint venture made distributions of $3.5 million to the noncontrolling interest and $3.5 million to us during the three and six months ended June 30, 2019. No distributions were made during the six months ended June 30, 2018. In addition, we did not make any capital contributions to the Carlsbad joint venture during the six months ended June 30, 2019 and 2018. The project was substantially complete as of December 31, 2018 and the warranty period expires in December 2020.

The carrying value of the assets and liabilities associated with the operations of the Carlsbad joint venture are included in our Condensed Consolidated Balance Sheets as follows (in thousands):

The project has been completed, the project warranty period has expired, and the dissolution of the joint venture was completed in the first quarter of 2019. The Wilmington joint venture made a final immaterial distribution to the noncontrolling interest and to us during the first quarter of 2019. No distributions were made during the six months ended June 30, 2018. In addition, we did not make any capital contributions to the Wilmington joint venture during the six months ended June 30, 2019 and 2018. The carrying value of the assets and liabilities associated with the operations of the Wilmington joint venture were included in our Condensed Consolidated Balance Sheet and were immaterial at December 31, 2018.

Stock-Based Compensation.

Stock-Based Compensation

Note 12—Stock-Based Compensation

In May 2013, the shareholders approved and we adopted the Primoris Services Corporation 2013 Long-term Incentive Equity Plan (“Equity Plan”). Our Board of Directors has granted 423,105 Restricted Stock Units (“Units”), net of forfeitures to employees under the Equity Plan. The grants were documented in RSU Award Agreements, which provide for a vesting schedule and require continuing employment of the employee. The Units are subject to earlier acceleration, termination, cancellation or forfeiture as provided in the underlying RSU Award Agreement.

At June 30, 2019, a total of 254,955 Units were vested. The vesting schedule for the remaining Units are as follows:

	Number of Units
For the Years Ending December 31,	to Vest
2019 (remaining six months)	4,393
2020	11,067
2021	122,649
2022	27,700
2023	2,341
	168,150

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. We recognized $0.4 million and $0.2 million in compensation expense for the three months ended June 30, 2019 and 2018, respectively, and $0.9 million and $0.4 million for the six months ended June 30, 2019 and 2018, respectively. At June 30, 2019, approximately $2.9 million of unrecognized compensation expense remained for the Units, which will be recognized over a weighted average period of 2.2 years.

Vested Units accrue “Dividend Equivalent Units” (as defined in the Equity Plan), which will be accrued as additional Units until the Units are converted to Common Stock.  At June 30, 2019, a total of 1,745 Dividend Equivalent Units were accrued.

Income Taxes

Income Taxes

Note 13—Income Taxes

We are subject to tax liabilities imposed by multiple jurisdictions. We determine our best estimate of the annual effective tax rate at each interim period using expected annual pre-tax earnings, statutory tax rates, and available tax planning opportunities. Certain significant or unusual items are separately recognized in the quarter in which they occur which can cause variability in the effective tax rate from quarter to quarter. We recognize interest and penalties related to uncertain tax positions, if any, as an income tax expense.

We do not include the income tax expense or benefit related to the net earnings or loss attributable to noncontrolling interest in our income tax expense as the entities are considered pass-through entities and, as such, the income tax expense or benefit is attributable to its owners. The effective tax rate on income including noncontrolling interests for the six months ended June 30, 2019 and 2018 was 28.0% and 17.5%, respectively. Excluding noncontrolling interest, the effective tax rate on income attributable to Primoris for the six months ended June 30, 2019 and 2018 was 29.0% and 24.0%, respectively. For the first six months of 2019, our tax rate differs from the U.S. federal statutory rate of 21.0% primarily due to the impact of state income taxes and nondeductible components of per diem expenses. For the first six months of 2018, our tax rate differs from the U.S. federal statutory rate of 21.0% primarily due to the impact of state income taxes, investment tax credits, and nondeductible components of per diem expenses.

Our U.S. federal income tax returns are generally no longer subject to examination for tax years before 2015. The statutes of limitation of state and foreign jurisdictions generally vary between 3 to 5 years. Accordingly, our state and foreign income tax returns are generally no longer subject to examination for tax years before 2013.

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for temporary differences between the financial reporting bases and tax bases of assets and liabilities based

on enacted tax rates expected to be in effect when such amounts are realized or settled. However, deferred tax assets are recognized only to the extent that it is more likely than not that they will be realized based upon consideration of available evidence, including future reversals of existing taxable temporary differences, future projected taxable income, the length of the tax asset carryforward periods, and tax planning strategies. The effects of remeasurement of deferred tax assets and liabilities resulting from changes in tax rates are recognized in income in the period of enactment.

Common stock

We issued 114,106 and 71,757 shares of common stock in the six months ended June 30, 2019 and 2018, respectively, under our long-term retention plan (“LTR Plan”). The shares were purchased by the participants in the LTR Plan with payment made to us of $1.8 million and $1.5 million in the six months ended June 30, 2019 and 2018, respectively. Our LTR Plan for managers and executives allows participants to use a portion of their annual bonus amount to purchase our common stock at a discount from the market price. The shares purchased in the six months ended June 30, 2019 were for bonus amounts earned in 2018, and the number of shares was calculated at 75% of the average daily closing market price during December 2018. The shares purchased in the six months ended June 30, 2018

were for bonus amounts earned in 2017, and the number of shares was calculated at 75% of the average closing market price of December 2017.

In February 2019 and 2018, we issued 13,278 and 10,062 shares of common stock, respectively, as part of the quarterly compensation of the non-employee members of the Board of Directors.

During the three and six months ended June 30, 2019, a total of 122,319 Units, net of forfeitures for tax withholdings, were converted to common stock. There were no Units converted to common stock during the six months ended June 30, 2018.

As discussed in Note 12 — “Stock–Based Compensation”, as of June 30, 2019, the Board of Directors has granted a total of 423,105 shares of Units, net of forfeitures under the Equity Plan and a total of 1,745 Dividend Equivalent Units were accrued at June 30, 2019.

Leases

Note 16—Leases

We lease administrative and fabrication facilities, which are generally longer-term, project specific facilities or yards, and construction equipment under non-cancelable operating leases. On January 1, 2019, we adopted ASC 842, “Leases” using the modified retrospective method and elected to apply the new lease standard at the adoption date. The cumulative impact of adopting ASC 842 was immaterial and did not require an adjustment to retained earnings. In adopting ASC 842, we changed our accounting policy for leases. Under the modified retrospective method, results for periods prior to January 1, 2019, are not adjusted and continue to be reported in accordance with our historic accounting under ASC 840, “Leases”.

We elected certain transition practical expedients permitted with the new standard, which among other things, allowed us to carry forward the historical lease classification. In addition, we elected the hindsight practical expedient to determine the reasonably certain lease term for existing leases. We also made an accounting policy election in which leases with an initial term of 12 months or less are not recorded on the balance sheet and lease payments are recognized in the Condensed Consolidated Statements of Income on a straight-line basis over the lease term.

We determine if an arrangement is a lease at inception. We have lease agreements with lease and non-lease components, which are generally accounted for separately. Operating leases are included in operating lease assets, accrued liabilities, and noncurrent operating lease liabilities on our Condensed Consolidated Balance Sheets.

Operating lease assets and operating lease liabilities are recognized at commencement date based on the present value of the future minimum lease payments over the lease term. In determining our lease term, we include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date to determine the present value of future payments. Lease expense from minimum lease payments is recognized on a straight-line basis over the lease term.

Our leases have remaining lease terms that expire at various dates through 2029, some of which may include options to extend the leases for up to 5 years. The exercise of lease extensions is at our sole discretion. Periodically, we sublease excess facility space, but any sublease income is generally not significant. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

The components of lease expense are as follows (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,

Note 17—Commitments and Contingencies

NTTA settlement — On February 7, 2012, we were 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”). On February 25, 2015, the Lawsuit was settled, and we recorded a liability for $17.0 million. A second defendant agreed to provide up to $5.4 million to pay for the total expected remediation cost of approximately $22.4 million. We will pay a third-party contractor approved by the NTTA to complete the remediation. In the event that the total remediation costs exceed the $22.4 million, the second defendant would pay 20% of the excess amount and we would pay for 80% of the excess amount. During the six months ended June 30, 2019, we increased our liability by $1.6 million. We also spent $5.0 million for remediation during the six months ended June 30, 2019. While we continue to monitor the progress toward remediation and the total remediation costs, at this time we cannot determine the eventual remediation cost. At June 30, 2019, the remaining accrual balance was $15.1 million.

Legal proceedings —We are subject to other claims and legal proceedings arising out of our business. We provide for costs related to contingencies when a loss from such claims is probable and the amount is reasonably estimable. In determining whether it is possible to provide an estimate of loss, or range of possible loss, we review and evaluate our 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 probable but not 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 defenses to such claims and believes that the reasonably possible outcome of such claims will not, individually or in the aggregate, have a material adverse effect on our consolidated results of operations, financial condition or cash flow.

Bonding — At June 30, 2019 and December 31, 2018, the Company had bid and completion bonds issued and outstanding totaling approximately $598.7 million and $554.9 million, respectively.

Reportable Segments

Note 18—Reportable Segments

We segregate our business into five reportable segments: the Power segment, the Pipeline segment, the Utilities segment, the Transmission segment, and the Civil segment. Each of our reportable segments is comprised of similar business units that specialize in services unique to the segment. Driving the end-user focused segments are differences in the economic characteristics of each segment, the nature of the services provided by each segment; the production processes of each segment; the type or class of customer using the segment’s services; the methods used by the segment to provide the services; and the regulatory environment of each segment’s customers.

The classification of revenue and gross profit for segment reporting purposes can at times require judgment on the part of management. Our segments may perform services across industries or perform joint services for customers in multiple industries. To determine reportable segment gross profit, certain allocations, including allocations of shared and indirect costs, such as facility costs, equipment costs and indirect operating expenses, were made.

The following is a brief description of the reportable segments:

The Power segment operates throughout the United States and in Canada and specializes in a range of services that include full EPC project delivery, turnkey construction, retrofits, upgrades, repairs, outages, specialty services, fabrication, material lining, and maintenance for entities in the power, solar, petroleum, petrochemical, water, and other industries.

The Pipeline segment operates throughout the United States and specializes in a range of services, including pipeline construction, pipeline maintenance, pipeline integrity, pipeline facility work, compressor stations, pump stations, metering facilities, and other pipeline related services for entities in the petroleum and petrochemical industries.

The Utilities segment operates primarily in California, the Midwest, the Atlantic Coast, and the Southeast regions of the United States and specializes in a range of services, including gas utility line installation, replacement and maintenance, gas distribution, and fiber optic cable installation.

The Transmission segment operates primarily in the Southeastern, Midwest, Atlantic Coast, and Gulf Coast regions of the United States and specializes in a range of services in electric transmission and distribution, streetlight maintenance and construction, substation construction and specialty services, fiber optic cable installation, comprehensive engineering, procurement, maintenance and construction, repair, and restoration of utility infrastructure.

The Civil segment operates primarily in the Southeastern and Gulf Coast regions of the United States and specializes in highway and bridge construction, airport runway and taxiway construction, demolition, site clearing and grading, heavy earthwork, soil stabilization, mass excavation, and drainage projects.

All intersegment revenue and gross profit, which were immaterial, have been eliminated in the following tables.

Basis of Presentation

Revenue recognition

We generate revenue under a range of contracting types, including fixed-price, unit-price, time and material, and cost reimbursable plus fee contracts. A substantial portion of our revenue is derived from contracts that are fixed-price or unit-price and is recognized over time as work is completed because of the continuous transfer of control to the customer (typically using an input measure such as costs incurred to date relative to total estimated costs at completion to measure progress). For time and material and cost reimbursable plus fee contracts, revenue is recognized primarily on an input basis, based on contract costs incurred as defined within the respective contracts. Costs to obtain contracts are generally not significant and are expensed in the period incurred.

We evaluate whether two or more contracts should be combined and accounted for as one single performance obligation and whether a single contract should be accounted for as more than one performance obligation. ASC 606 defines a performance obligation as a contractual promise to transfer a distinct good or service to a customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Our evaluation requires significant judgment and the decision to combine a group of contracts or separate a contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. The majority of our contracts have a single performance obligation, as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contract and, therefore, is not distinct. However, occasionally we have contracts with multiple performance obligations. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using the observable standalone selling price, if available, or alternatively our best estimate of the standalone selling price of each distinct

performance obligation in the contract. The primary method used to estimate standalone selling price is the expected cost plus a margin approach for each performance obligation.

As of June 30, 2019, we had $1.93 billion of remaining performance obligations. We expect to recognize approximately 55% of our remaining performance obligations as revenue during the next four quarters and substantially all of the remaining balance by the second quarter of 2021.

Accounting for long-term contracts involves the use of various techniques to estimate total transaction price and costs. For long-term contracts, transaction price, estimated cost at completion and total costs incurred to date are used to calculate revenue 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 revenue 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 nature of our contracts gives rise to several types of variable consideration, including contract modifications (change orders and claims), liquidated damages, volume discounts, performance bonuses, incentive fees, and other terms that can either increase or decrease the transaction price. We estimate variable consideration as the most likely amount to which we expect to be entitled. We include estimated amounts in the transaction price to the extent we believe we have an enforceable right, and it is probable that a significant reversal of cumulative revenue recognized will not occur. Our estimates of variable consideration and the determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us at this time.

Contract modifications result from changes in contract specifications or requirements. We consider unapproved change orders to be contract modifications for which customers have not agreed to both scope and price. We consider claims to be contract modifications for which we seek, 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. Claims can also be caused by non-customer-caused changes, such as rain or other weather delays. Costs associated with contract modifications are included in the estimated costs to complete the contracts and are treated as project costs when incurred. In most instances, contract modifications are for goods or services that are not distinct, and, therefore, are accounted for as part of the existing contract. The effect of a contract modification on the transaction price, and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis. In some cases, settlement of contract modifications may not occur until after completion of work under the contract.

As a significant change in one or more of these estimates could affect the profitability of our contracts, we review and update our contract-related estimates regularly. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the cumulative impact of the profit adjustment is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance are recognized using the adjusted estimate. In the three and six months ended June 30, 2019, revenue recognized from performance obligations satisfied in previous periods was $4.2 million and $10.7 million, respectively. If at any time the estimate of contract profitability indicates an anticipated loss on a contract, the projected loss is recognized in full, including any previously recognized profit, in the period it is identified and recognized as an “accrued loss provision” which is included in “Contract liabilities” on the Condensed Consolidated Balance Sheets. For contract revenue recognized over time, the accrued loss provision is adjusted so that the gross profit for the contract remains zero in future periods.

At June 30, 2019, we had approximately $84.1 million of unapproved contract modifications included in the aggregate transaction prices. These contract modifications were in the process of being negotiated in the normal course of business. Approximately $79.3 million of the contract modifications had been recognized as revenue on a cumulative catch-up basis through June 30, 2019.

In all forms of contracts, we estimate the collectability of contract amounts at the same time that we estimate project costs. If we anticipate that there may be issues associated with the collectability of the full amount calculated as

the transaction price, we 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.

The timing of when we bill our customers is generally dependent upon agreed-upon contractual terms, milestone billings based on the completion of certain phases of the work, or when services are provided. Sometimes, billing occurs subsequent to revenue recognition, resulting in unbilled revenue, which is a contract asset. Also, we sometimes receive advances or deposits from our customers before revenue is recognized, resulting in deferred revenue, which is a contract liability.

The caption “Contract assets” in the Condensed Consolidated Balance Sheets represents the following:

● unbilled revenue, which arise when revenue has been recorded but the amount will not be billed until a later date;

● retainage amounts for the portion of the contract price earned by us for work performed, but held for payment by the customer as a form of security until we reach certain construction milestones; and

● contract materials for certain job specific materials not yet installed, which are valued using the specific identification method relating the cost incurred to a specific project.

Customer concentration

Customer concentration — We operate in multiple industry segments encompassing the construction of commercial, industrial and public works infrastructure assets primarily throughout the United States. Typically, the top ten customers in any one calendar year generate revenue that is approximately 50% of total revenue; however, the group that comprises the top ten customers varies from year to year.

During the three and six months ended June 30, 2019, revenue generated by the top ten customers was approximately $372.4 million and $696.5 million, respectively, which represented 47.1% and 48.0%, respectively of total revenue during the period. During the three and six months ended June 30, 2019, a Midwest utility customer represented 8.0% and 6.7% of total revenue, respectively, and an electric utility customer represented 7.6% and 8.3% of total revenue, respectively.

During the three and six months ended June 30, 2018, revenue generated by the top ten customers was approximately $322.6 million and $581.6 million, respectively, which represented 50.4% and 49.7%, respectively, of total revenue during the period. During the three and six months ended June 30, 2018, a state department of transportation customer represented 9.4% and 9.3% of total revenue, respectively, and a California utility customer represented 8.7% and 9.0% of total revenue, respectively.

At June 30, 2019, approximately 8.7% of our accounts receivable was due from one customer, and that customer provided 8.3% of our revenue for the six months ended June 30, 2019.

On January 29, 2019, one of our utility customers filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. As of June 30, 2019, the utility customer comprised approximately 14.0% of our total accounts receivable. In addition to accounts receivable, there is approximately $15.8 million in unbilled revenue, net as of June 30, 2019. For the three and six months ended June 30, 2019, the customer accounted for approximately 5.9% and 5.7%, respectively, of our total revenue. A portion of the accounts receivable balance is past due, but we do not believe a reserve for the accounts receivable and unbilled revenue is appropriate at this time. However, we will closely monitor our current and future potential exposure.
