STERLING CONSTRUCTION COMPANY, INC. & SUBSIDIARIES
NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
March 31, 2021
($ and share values in thousands, except per share data)
(Unaudited)
1.NATURE OF OPERATIONS
Business Summary
Sterling Construction Company, Inc., (“Sterling,” “the Company,” “we,” “our” or “us”), a Delaware corporation, operates through a variety of subsidiaries within three segments specializing in Heavy Civil, Specialty Services and Residential projects in the United States (the “U.S.”), primarily across the southern U.S., the Rocky Mountain States, California and Hawaii, as well as other areas with strategic construction opportunities. Heavy Civil includes infrastructure and rehabilitation projects for highways, roads, bridges, airfields, ports, light rail, water, wastewater and storm drainage systems. Specialty Services projects include land development activities (including site excavation and drainage, drilling and blasting for excavation), foundations for multi-family homes, parking structures and other commercial concrete projects. Residential projects include concrete foundations for single-family homes.
2.BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
Presentation Basis—The accompanying Condensed Consolidated Financial Statements are presented in accordance with accounting policies generally accepted in the United States (“GAAP”) and reflect all wholly owned subsidiaries and those entities the Company is required to consolidate. See Note 4 - Consolidated 50% Owned Subsidiaries and Note 5 - Construction Joint Ventures for further discussion of the Company’s consolidation policy for those entities that are not wholly owned. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation have been included. All significant intercompany accounts and transactions have been eliminated in consolidation. Values presented within tables (excluding per share data) are in thousands. Reclassifications have been made to historical financial data in the Condensed Consolidated Financial Statements to conform to the current year presentation.
Estimates and Judgments—The preparation of the accompanying Condensed Consolidated Financial Statements in conformance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Certain accounting estimates of the Company require a higher degree of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts over time, the valuation of long-lived assets, goodwill and purchase accounting estimates. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.
Significant Accounting Policies
Consistent with Regulation S-X Rule 10-1(a), the Company has omitted significant accounting policies in this quarterly report that would duplicate the disclosures contained in the Company’s annual report on Form 10-K for the year ended December 31, 2020 under “Part II, Item 8. - Notes to Consolidated Financial Statements.” This quarterly report should be read in conjunction with the Company’s most recent annual report on Form 10-K.
Accounts Receivable—Receivables are generally based on amounts billed to the customer in accordance with contractual provisions. Receivables are written off based on the individual credit evaluation and specific circumstances of the customer, when such treatment is warranted. The Company performs a review of outstanding receivables, historical collection information and existing economic conditions to determine if there are potential uncollectible receivables. At March 31, 2021 and December 31, 2020, our allowance for our estimate of expected credit losses was zero.
As is customary, we have agreed to indemnify our bonding company for all losses incurred by it in connection with bonds that are issued, and we have granted our bonding company a security interest in certain assets, including accounts receivable, as collateral for such obligation.
8


Contracts in Progress—For performance obligations satisfied over time, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Typically, Sterling bills for advances or deposits from its customers before revenue is recognized, resulting in contract liabilities. However, the Company occasionally bills subsequent to revenue recognition, resulting in contract assets.
Many of the contracts under which the Company performs work also contain retainage provisions. Retainage refers to that portion of our billings held for payment by the customer pending satisfactory completion of the project. Unless reserved, the Company assumes that all amounts retained by customers under such provisions are fully collectible. At March 31, 2021 and December 31, 2020, contract assets included $43,824 and $44,412 of retainage, respectively, and contract liabilities included $35,832 and $33,856 of retainage, respectively. Retainage on active contracts is classified as current regardless of the term of the contract and is generally collected within one year of the completion of a contract. We anticipate collecting approximately 69% of our March 31, 2021 retainage during the next twelve months. These assets and liabilities are reported on the Condensed Consolidated Balance Sheet within “Contract assets” and “Contract liabilities” on a contract-by-contract basis at the end of each reporting period.
Revenue recognized for the three months ended March 31, 2021 that was included in the contract liability balance on December 31, 2020 was $155,558. Revenue recognized for the three months ended March 31, 2020 that was included in the contract liability balance on December 31, 2019 was $146,266.
Cash and Restricted Cash—Our cash is comprised of highly liquid investments with maturities of three months or less. Restricted cash of approximately $5,800 and $6,500 is included in “Other current assets” on the Condensed Consolidated Balance Sheets at March 31, 2021 and December 31, 2020, respectively. This primarily represents cash deposited by the Company into separate accounts and designated as collateral for standby letters of credit in the same amount in accordance with contractual agreements.
3.REVENUE FROM CUSTOMERS
BacklogThe following table presents the Company’s backlog, by segment:
March 31,
2021
December 31,
2020
Heavy Civil Backlog$1,261,461 $898,183 
Specialty Services Backlog377,761 277,205 
Total Heavy Civil and Specialty Services Backlog$1,639,222 $1,175,388 
The Company expects to recognize approximately 52% of its backlog as revenue during the next twelve months, and the balance thereafter.

Revenue DisaggregationThe following tables present the Company’s revenue disaggregated by major end market and contract type:
Three Months Ended March 31,
Revenues by major end market20212020
Heavy Highway$99,516 $96,374 
Aviation27,222 28,457 
Water Containment and Treatment14,219 21,809

Land Development96,572 76,245 
Commercial27,516 28,478 
Specialty Services Revenues124,088 104,723 
Residential Revenues44,174 36,350 
Total Revenues$315,316 $296,688 
Revenues by contract type
Fixed-Unit Price$177,547 $141,739 
Lump Sum91,155 114,252 
Residential and Other46,614 40,697 
Total Revenues$315,316 $296,688 
Each of these contract types presents advantages and disadvantages. Typically, the Company assumes more risk with lump-sum contracts. However, these types of contracts offer additional profits if the work is completed for less than originally estimated. Under fixed-unit price contracts, the Company’s profit may vary if actual labor-hour costs vary significantly from the negotiated rates. Also, because some contracts can provide little or no fee for managing material costs, the components of contract cost can impact profitability.
Variable Consideration
The Company has projects that it is in the process of negotiating, or awaiting final approval of, unapproved change orders and claims with its customers. The Company is proceeding with its contractual rights to recoup additional costs incurred from its customers based on completing work associated with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope which resulted in substantial delays and additional costs in completing the work. Unapproved change order and claim information has been provided to the Company’s customers and negotiations with the customers are ongoing. If additional progress with an acceptable resolution is not reached, legal action will be taken. Based upon the Company’s review of the provisions of its contracts, specific costs incurred and other related evidence supporting the unapproved change orders and claims, together in some cases as necessary with the views of the Company’s outside claim consultants, the Company concluded it was appropriate to include in project price amounts of $7,142, at March 31, 2021 and December 31, 2020, relating to unapproved change orders and claims. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined.
Contract Estimates
Accounting for long-term contracts and programs involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, the Company estimates the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract and recognizes such profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that often span several years. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials and the performance of subcontractors. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Changes in estimated revenues and gross margin resulted in a net increase of approximately $8,305 for the three months ended March 31, 2021, and net increase of approximately $95 for the three months ended March 31, 2020, included in “Operating income” on the Condensed Consolidated Statements of Operations.

4.CONSOLIDATED 50% OWNED SUBSIDIARIES
The Company has 50% ownership interests in two subsidiaries (“Myers” and “RHB”) that it fully consolidates as a result of its exercise of control over the entities. The earnings attributable to the 50% portions the Company does not own were approximately $1,800 and $1,700 for the three months ended March 31, 2021 and 2020, respectively, and are eliminated within “Other operating expense, net” in the Condensed Consolidated Statements of Operations. Any undistributed earnings for partners are included in “Members’ interest subject to mandatory redemption and undistributed earnings” within the Condensed Consolidated Balance Sheets and are mandatorily payable at the time of the noncontrolling owners’ death or permanent disability.
These two subsidiaries have individual mandatory redemption provisions which, under circumstances outlined in the partner agreements, are certain to occur and obligate the Company to purchase each partner’s remaining 50% interests for $20,000 ($40,000 in the aggregate). The Company has purchased two separate $20,000 death and permanent total disability insurance policies to mitigate the Company’s cash draw if such events were to occur. These purchase obligations are also recorded in “Members’ interest subject to mandatory redemption and undistributed earnings” on the Condensed Consolidated Balance Sheets.
The liability consists of the following:
March 31,
2021
December 31,
2020
Members’ interest subject to mandatory redemption$40,000 $40,000 
Net accumulated earnings11,615 11,290 
Total liability$51,615 $51,290 
The Company must determine whether any of its entities, including these two 50% owned subsidiaries, in which it participates, is a VIE. The Company determined that Myers is a VIE and that the Company is the primary beneficiary because pursuant to the terms of the Myers Operating Agreement, the Company is exposed to the majority of potential losses of the partnership.
Summary financial information for Myers is as follows:
Three Months Ended March 31,
20212020
Revenues$27,957 $44,362 
Operating income$718 $155 
Net income$352 $79 
5.CONSTRUCTION JOINT VENTURES
Joint Ventures with a Controlling Interest—We consolidate any venture that is determined to be a VIE for which we are the primary beneficiary, or which we otherwise effectively control. The equity held by the remaining owners and their portions of net income (loss) are reflected in stockholders’ equity on the Condensed Consolidated Balance Sheets line item “Noncontrolling interests” and in the Condensed Consolidated Statements of Operations line item “Net income attributable to noncontrolling interests,” respectively. The Company determined that a joint venture in which the Company’s Ralph L. Wadsworth Construction subsidiary is a 51% owner is a VIE and the Company is the primary beneficiary. Summary financial information for this construction joint venture is as follows:
Three Months Ended March 31,
20212020
Revenues$8,242 $4,064 
Operating income$2,527 $296 
Net income$2,528 $299 
11


Joint Ventures with a Noncontrolling Interest—The Company accounts for unconsolidated joint ventures using a pro-rata basis in the Condensed Consolidated Statements of Operations and as a single line item (“Receivables from and equity in construction joint ventures”) in the Condensed Consolidated Balance Sheets. This method is a permissible modification of the equity method of accounting which is a common practice in the construction industry. Combined financial amounts of joint ventures in which the Company has a noncontrolling interest and the Company’s share of such amounts which are included in the Company’s Condensed Consolidated Financial Statements are shown below:
March 31,
2021
December 31,
2020
Current assets$141,199 $143,608 
Current liabilities$(100,730)$(141,295)
Sterling’s receivables from and equity in construction joint ventures$18,166 $16,653 
Three Months Ended March 31,
20212020
Revenues$49,417 $26,846 
Income before tax$4,635 $2,157 
Sterling’s noncontrolling interest:
Revenues$21,944 $13,082 
Income before tax$2,135 $1,049 
The caption “Receivables from and equity in construction joint ventures” includes undistributed earnings and receivables owed to the Company. Undistributed earnings are typically released to the joint venture partners after the customer accepts the project as completed and the warranty period, if any, has passed.
Other—The use of joint ventures exposes us to a number of risks, including the risk that our partners may be unable or unwilling to provide their share of capital investment to fund the operations of the venture or complete their obligations to us, the venture, or ultimately, the customer. Differences in opinions or views among joint venture partners could also result in delayed decision-making or failure to agree on material issues, which could adversely affect the business and operations of the joint venture. In addition, agreement terms may subject us to joint and several liability for our venture partners, and the failure of our venture partners to perform their obligations could impose additional performance and financial obligations on us. The aforementioned factors could result in unanticipated costs to complete the projects, liquidated damages or contract disputes, including claims against our partners.

Less - Unamortized debt issuance costs(5,717)(6,714)
Total long-term debt$279,175 $291,249 
Credit Facility—Our amended credit agreement (“Credit Agreement”) provides the Company with senior secured debt financing in an amount up to $475,000 in the aggregate, consisting of (i) a senior secured first lien term loan facility (the “Term Loan Facility”) in the amount of $400,000 (collectively, the “Credit Facility”) and (ii) a senior secured first lien revolving credit facility (the “Revolving Credit Facility”) in an aggregate principal amount of $75,000 (with a $75,000 limit for the issuance of letters of credit and a $15,000 sublimit for swing line loans). The obligations under the Credit Facility are secured by substantially all assets of the Company and the subsidiary guarantors, subject to certain permitted liens and interests of other parties. The Credit Facility will mature on October 2, 2024.
The Term Loan Facility bears interest at either the base rate plus a margin, or at a one-, two-, three-, six- or, if available, twelve-month LIBOR rate plus a margin, at the Company’s election. At March 31, 2021, the Company calculated interest using a one-month LIBOR rate and an applicable margin of 0.15% and 4.50% per annum, respectively. We continue to utilize an interest rate swap to hedge against $275,000 of the outstanding Term Loan Facility, which resulted in a weighted average interest rate of approximately 5.62% per annum during the three months ended March 31, 2021. Scheduled principal payments on the Term Loan Facility total $50,000, $50,000, $50,000 and $15,000 for each of the years ending 2021, 2022, 2023, and 2024, respectively, and the Company is required to make payments quarterly. The Company is required to make mandatory prepayments on the Credit Facility with proceeds received from issuances of debt, events of loss and certain dispositions. The Company also is required to prepay the Credit Facility with its excess cash flow within 5 days after receipt of its annual audited financial statements. For the three months ended March 31, 2021, the company made a scheduled term loan payment of $12,500 and an excess cash flow payment of $18,000. A final payment of all principal and interest then outstanding on the Term Loan Facility is due on October 2, 2024.
The Revolving Credit Facility bears interest at the same rate options as the Term Loan Facility. In addition to interest on debt borrowings, we are assessed quarterly commitment fees on the unutilized portion of the facility as well as letter of credit fees on outstanding instruments. At March 31, 2021, we had no outstanding borrowings under the Revolving Credit Facility, providing $75,000 of available capacity.
13


Debt Issuance Costs—The costs associated with the Term Loan Facility and Revolving Credit Facility are reflected on the Condensed Consolidated Balance Sheets as a direct reduction from the related debt liability and amortized over the terms of the respective facilities. Amortization of debt issuance costs was $660 and $752 for the three months ended March 31, 2021 and 2020, respectively, and was recorded as interest expense. Additionally, due to an early payment of $18,000 on the Term Loan Facility in the first quarter of 2021, we recorded a loss on debt extinguishment of $337 related to debt issuance costs.
Compliance and Other—The Credit Agreement contains various affirmative and negative covenants that may, subject to certain exceptions, restrict the ability of us and our subsidiaries to, among other things, grant liens, incur additional indebtedness, make loans, advances or other investments, make non-ordinary course asset sales, declare or pay dividends or make other distributions with respect to equity interests, purchase, redeem or otherwise acquire or retire capital stock or other equity interests, or merge or consolidate with any other person, among various other things. In addition, the Company is required to maintain certain financial covenants. As of March 31, 2021, we were in compliance with all of our restrictive and financial covenants. The Company’s debt is recorded at its carrying amount in the Condensed Consolidated Balance Sheets. At March 31, 2021 and December 31, 2020, the carrying values of our debt outstanding approximated the fair values.
9.FINANCIAL INSTRUMENTS
    Interest Rate Derivative—We continue to utilize a swap arrangement to hedge against interest rate variability associated with $275,000 of the $324,500 outstanding under the Term Loan Facility. The Company has designated its interest rate swap agreement as a cash flow hedging derivative. To the extent the derivative instrument is effective and the documentation requirements have been met, changes in fair value are recognized in other comprehensive income (loss) (“OCI”) until the underlying hedged item is recognized in earnings. At March 31, 2021 the fair value of the swap recorded in accumulated other comprehensive income (loss) (“AOCI”) was a net loss of $5,662.
Derivatives Disclosures
    Fair Value—Financial instruments are required to be categorized within a valuation hierarchy based upon the lowest level of input that is significant to the fair value measurement. The three levels of the valuation hierarchy are as follows:
Level 1—Fair value is based on quoted prices in active markets.
Level 2—Fair value is based on internally developed models that use, as their basis, readily observable market parameters. Our derivative positions are classified within level 2 of the valuation hierarchy as they are valued using quoted market prices for similar assets and liabilities in active markets. These level 2 derivatives are valued utilizing an income approach, which discounts future cash flow based on current market expectations and adjusts for credit risk.
Level 3—Fair value is based on internally developed models that use, as their basis, significant unobservable market parameters. The Company did not have any level 3 classifications at March 31, 2021 or December 31, 2020.
    The following table presents the fair value of the interest rate derivative by valuation hierarchy and balance sheet classification:

11.COMMITMENTS AND CONTINGENCIES
The Company is required by its insurance providers to obtain and hold standby letters of credit. These letters of credit serve as a guarantee by the banking institution to pay the Company’s insurance providers the incurred claim costs attributable to its general liability, workers compensation and automobile liability claims, up to the amount stated in the standby letters of credit, in the event that these claims were not paid by the Company. These letters of credit are cash collateralized, resulting in the cash being designated as restricted.
The Company, including its construction joint ventures and its consolidated 50% owned subsidiaries, is now and may in the future be involved as a party to various legal proceedings that are incidental to the ordinary course of business. Management, after consultation with legal counsel, does not believe that the outcome of these actions will have a material impact on the Condensed Consolidated Financial Statements of the Company.
12.INCOME TAXES
The Company and its subsidiaries are based in the U.S. and file federal and various state income tax returns. The components of the provision for income taxes were as follows:
Three Months Ended March 31,
20212020
Current tax expense$618 $271 
Deferred tax expense4,142 913 
Income tax expense$4,760 $1,184 
Cash paid for income taxes$ $44 
The 2021 effective income tax rate varied from the statutory rate primarily as a result of state income taxes, nondeductible compensation and other permanent differences.
Due to net operating loss carryforwards, the Company expects no cash payments for federal income taxes for 2021 or 2020. The Company makes cash payments for state income taxes in states in which the Company does not have net operating loss carry forwards.
At December 31, 2020 the Company had federal and state net operating loss (“NOL”) carryforwards of $58,719 and $36,381, respectively, which expire at various dates in the next 18 years for U.S. federal income tax and in the next 7 to 18 years for the various state jurisdictions where we operate. Such NOL carryforwards expire beginning in 2028 through 2039.
As a result of the Company’s analysis, management has determined that the Company does not have any material uncertain tax positions.

13.STOCK INCENTIVE PLAN AND OTHER EQUITY ACTIVITY
General—The Company has a stock incentive plan (the “Stock Incentive Plan”) and an employee stock purchase plan (the “ESPP”) that are administered by the Compensation and Talent Development Committee of the Board of Directors. Under the Stock Incentive Plan, the Company can issue shares to employees and directors in the form of restricted stock awards (“RSAs”), restricted stock units (“RSUs”) and performance share units (“PSUs”). Changes in common stock, additional paid in capital and treasury stock during the three months ended March 31, 2021 primarily relate to activity associated with the Stock Incentive Plan, the ESPP and shares withheld for taxes.
Share GrantsDuring the three months ended March 31, 2021, the Company had the following share grants associated with the Stock Incentive Plan:
SharesWeighted Average Grant-Date Fair Value per Share
RSUs108 $18.95 
PSUs (at target)139 $18.84 
Total shares granted247 
Share IssuancesDuring the three months ended March 31, 2021, the Company had the following share issuances associated with the Stock Incentive Plan and the ESPP:
Shares
RSUs (issued upon vesting)40 
PSUs (issued upon vesting)621 
ESPP (issued upon sale)7 
Total shares issued668 
Stock-Based Compensation Expense—During the three months ended March 31, 2021 and 2020, the Company recognized $1,835 and $2,234, respectively, of stock-based compensation expense, primarily within general and administrative expenses. The Company recognizes forfeitures as they occur, rather than estimating expected forfeitures. Included within total stock-based compensation expense for the three months ended March 31, 2021 and 2020 is $25 and $18, respectively, of expense related to the ESPP.
Shares Withheld for Taxes—The Company withheld 246 shares for taxes on RSU/PSU stock-based compensation vestings for $5,619 during the three months ended March 31, 2021.
AOCI—During the three months ended March 31, 2021, changes in AOCI were a result of net gains (losses) recognized in OCI and amounts reclassified from AOCI into earnings related to our interest rate derivative. See Note 9 - Financial Instruments for further discussion.

OVERVIEW

General—Sterling Construction Company, Inc. (“Sterling” or “the Company”), operates through a variety of subsidiaries within three segments specializing in Heavy Civil, Specialty Services and Residential projects in the United States (the “U.S.”), primarily across the southern U.S., the Rocky Mountain States, California and Hawaii, as well as other areas with strategic construction opportunities. Heavy Civil includes infrastructure and rehabilitation projects for highways, roads, bridges, airfields, ports, light rail, water, wastewater and storm drainage systems. Specialty Services projects include land development activities (including site excavation and drainage, drilling and blasting for excavation), foundations for multi-family homes, parking structures and other commercial concrete projects. Residential projects include concrete foundations for single-family homes.
Impact of COVID-19—The Company continues to monitor closely the actual and expected impacts of the COVID-19 pandemic on our business, financial condition and results of operations. Sterling’s business has been identified as a component of “Essential Critical Infrastructure” per the National Cybersecurity and Infrastructure Agency, and to date, we have not experienced significant shutdowns of project sites or operational interruptions. Consistent with governmental orders and public health guidelines, the Company has continued to operate across its footprint. While the Company has not incurred significant disruptions thus far from the COVID-19 pandemic, the pandemic may impact our business, condensed consolidated results of operations and financial condition in the future. However, the significance of the impact on our operations going forward is not yet certain and depends on numerous evolving factors as discussed in more detail in the Company’s annual report on the 2020 Form 10-K under “Part I, Item 1A. Risk Factors.”
MARKET OUTLOOK AND TRENDS
Heavy Civil—Sterling’s Heavy Civil business is primarily driven by federal, state and municipal funding. Federal funds, on average, provide 50% of annual State Department of Transportation capital outlays for highway and bridge projects. Several of the states in Sterling’s key markets have instituted actions to further increase annual spending. In November 2020, various state and local transportation measures were passed securing, and in some cases increasing, funding of major initiatives in Texas ($7.5 billion) and California ($520 million). In addition to the state locally funded actions, the $305 billion 2015 federally funded Fixing America’s Surface Transportation (“FAST”) Act increased the annual federal highway investment by 15.1% over a five-year period from 2016 to 2020. In September 2020, Congress passed a one-year extension of the FAST Act which added an additional $13.6 billion to the Highway Trust Fund. In October 2018, the Federal Aviation Administration reauthorized $3.35 billion annually through 2023. This reauthorization also includes more than $1 billion a year for airport infrastructure grants and about $1.7 billion for disaster relief. Multiple infrastructure proposals are currently underway in both the federal House and the Senate. If passed, these bills could add additional multi-year funding for highways, rail and airports starting in late 2021 or early 2022.
Specialty Services—Sterling’s Specialty Services business is primarily driven by investments from end users and developers. Key end users, including Amazon, Facebook and Home Depot, have continued implementing publicly announced multi-year capital infrastructure campaigns. In our primary market in the southeastern United States, and specifically Georgia, the availability rate is at 6.5% and for ten consecutive quarters over 20 million square feet of new construction has commenced. The outlook for the multi-family market continues to decline, as developers face economic concerns due to the COVID-19 pandemic and the availability and affordability of starter single family homes continues to rise.

Residential—Continuing revenue growth of the Company’s Residential business is directly related to the growth of new home starts in its key markets of Dallas-Fort Worth and Houston. The Company’s core customer base is primarily made up of leading national home builders as well as regional and custom home builders. The Company has continued its expansion of the residential business into the Houston market and surrounding areas. Additionally, over the last several quarters, the residential market has experienced significant price volatility and availability for key materials including concrete, lumber and steel. Generally, we pass these costs onto the Company’s customers, however, there is often a delay in the ability to recoup the full impact.
BACKLOG
At March 31, 2021, our backlog (“Backlog”) of construction projects, made up of our Heavy Civil and Specialty Services segments, was $1.6 billion, as compared to $1.2 billion at December 31, 2020. The contracts in Backlog are typically completed in 6 to 36 months. Contracts in which we are the apparent low bidder for projects (“Unsigned Low-bid Awards”) are excluded from Backlog until the contract is executed by our customer. Unsigned Low-bid Awards were $75.7 million at March 31, 2021 and $356.9 million at December 31, 2020. The combination of our Backlog and Unsigned Low-bid Awards, which we refer to as “Combined Backlog” totaled $1.7 billion and $1.5 billion as of March 31, 2021 and December 31, 2020, respectively.
20


The Company’s margin in Backlog has decreased from 12.0% at December 31, 2020 to 11.8% at March 31, 2021 and the Combined Backlog margin decreased from 11.8% at December 31, 2020 to 11.7% at March 31, 2021, driven by a greater mix of Heavy Civil awards.
RESULTS OF OPERATIONS
Consolidated Results
Summary—For the first quarter of 2021, the Company had operating income of $22.8 million, income before income taxes of $16.4 million, net income attributable to Sterling common stockholders of $10.6 million and net income per diluted share attributable to Sterling common stockholders of $0.37.
Consolidated financial highlights for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020 are as follows:

Gross margin14.3 %11.9 %

Revenues—Revenues were $315.3 million for the first quarter of 2021, an increase of $18.6 million or 6% compared with the first quarter of 2020. The increase in the first quarter of 2021 was driven by a $19.4 million increase in Specialty Services and a $7.8 million increase in Residential, partly offset by a $8.6 million decrease in Heavy Civil.
Gross profit—Gross profit was $45.0 million for the first quarter of 2021, an increase of $9.8 million or 28% compared to the first quarter of 2020. The Company’s gross margin as a percent of revenue increased to 14.3% in the first quarter of 2021, as compared to 11.9% in the first quarter of 2020. The increase in gross profit was primarily driven by higher volume from Specialty Services, and the ramp up of construction on large design-build joint venture projects as we continue to reduce the lower margin low-bid heavy highway revenues for Heavy Civil. The increase in gross margin as a percent of revenue was primarily driven by the aforementioned large design-build joint venture projects for Heavy Civil.
Contracts in progress which were not substantially completed totaled approximately 201 and 210 at March 31, 2021 and 2020, respectively. These contracts are of various sizes, of different expected profitability and in various stages of completion. The nearer a contract progresses toward completion, the more visibility the Company has in refining its estimate of total revenues (including incentives, delay penalties and change orders), costs and gross profit. Thus, gross profit as a percent of revenues can increase or decrease from comparable and subsequent quarters due to variations among contracts and depending upon the stage of completion of contracts.
Interest expense—Interest expense was $6.0 million in the first quarter of 2021 compared to $7.8 million in the first quarter of 2020. The decrease is due to the Company’s declining debt, as the Company has paid down $120.5 million of its Credit Facility balance since the first quarter of 2020.
Income taxes—The effective income tax rate was 29.0% in the first quarter of 2021 and the Company maintains its estimate of a 30% effective income tax rate for the full year 2021. Due to its net operating loss carryforwards, the Company expects no cash payments for federal income taxes for 2021 or 2020. See Note 12 - Income Taxes for more information.

Heavy Civil
Revenues—Revenues were $147.1 million for the first quarter of 2021, a decrease of $8.6 million or 5.5% compared to the first quarter of 2020. The decrease was primarily driven by lower water containment and treatment revenue for the first quarter of 2021 compared to the first quarter of 2020. Additionally, we continued to reduce our low-bid heavy highway revenue by $19.6 million and we replaced it with an increase of $22.7 million from heavy highway design build and other revenues during the first quarter of 2021.
Operating Income—Operating income was $1.1 million for the first quarter of 2021, an increase of $4.7 million, compared to the first quarter of 2020. The increase was the result of improved margin mix with the ramp up of construction on large design-build joint venture projects and the continuation of our planned revenue reduction from lower margin low-bid heavy highway work.

Revenues—Revenues were $124.1 million for the first quarter of 2021, an increase of $19.4 million or 18.5% compared to the first quarter of 2020. The increase was driven by higher volume from land development, partly offset by a decrease in commercial revenues in the first quarter of 2021.
Operating income—Operating income was $16.2 million for the first quarter of 2021, an increase of $5.1 million, compared to the first quarter of 2020. The increase was driven by the aforementioned higher volume from land development in the first quarter of 2021.
Residential
Revenues—Revenues were $44.2 million for the first quarter of 2021, an increase of $7.8 million or 21.5%, compared to the first quarter of 2020. The increase in revenue was primarily the result of a record number of slabs poured in the first quarter of 2021, reflecting the strong continuing demand for new housing in our Texas footprint.
Operating income—Operating income was $5.5 million for the first quarter of 2021, an increase of $0.4 million, compared to the first quarter of 2020. The increase was driven by the aforementioned volume increase, partly offset by higher material costs for concrete, lumber and steel, and the lack of consistent availability of these materials. As a result of the increase in material cost, operating income as a percent of revenue decreased 156 basis points compared to the first quarter of 2020. The Company has and will continue to work with Residential customers to recoup increases in material cost.

Investing activities(11,001)(6,842)
Financing activities(32,502)24,243 
Net change in cash and cash equivalents$(4,783)$28,172 
Operating Activities—During the three months ended March 31, 2021, net cash provided by operating activities was $38.7 million compared to net cash provided by operating activities of $10.8 million in the three months ended March 31, 2020. Cash flows provided by operating activities were driven by net income, adjusted for various non-cash items and changes in accounts receivable, net contracts in progress and accounts payable balances (collectively, “Contract Capital”), as discussed below, and other accrued liabilities.
Changes in Contract Capital—The change in operating assets and liabilities varies due to fluctuations in operating activities and investments in Contract Capital. The changes in the components of Contract Capital during the three months ended March 31, 2021 and 2020 were as follows:
Three Months Ended March 31,
(In thousands)20212020
Contracts in progress, net$(7,921)$(12,001)
Accounts receivable7,238 21,026 
Receivables from and equity in construction joint ventures(1,513)(1,593)
Accounts payable12,799 (14,421)
Change in Contract Capital, net$10,603 $(6,989)
During the three months ended March 31, 2021, the change in Contract Capital increased liquidity by $10.6 million. The Company’s Contract Capital fluctuations are impacted by the mix of projects in Backlog, seasonality, the timing of new awards, and related payments for work performed and the contract billings to the customer as projects are completed. Contract Capital is also impacted at period-end by the timing of accounts receivable collections and accounts payable payments for projects.

Investing Activities—During the three months ended March 31, 2021, net cash used in investing activities was $11.0 million, compared to net cash used of $6.8 million in the three months ended March 31, 2020. The use of cash was driven by purchases of capital equipment and buildings and improvements. Capital equipment is acquired as needed to support changing levels of production activities and to replace retiring equipment.
Financing Activities—During the three months ended March 31, 2021, net cash used in financing activities was $32.5 million, compared to net cash provided of $24.2 million in the prior year. The financing cash outflow was driven by $30.5 million of repayments on the Term Loan Facility and $2.0 million in distributions to noncontrolling interest owners.
Capital StrategyThe Company will continue to explore additional revenue growth and capital alternatives to improve leverage and strengthen its financial position in order to take advantage of trends in the civil infrastructure and specialty services markets. The Company expects to pursue strategic uses of its cash, such as, strategic acquisitions in its existing segments, or adding a new segment, of businesses that meet its gross margin targets and overall profitability and managing its debt balances.

JOINT VENTURES
We participate in various construction joint venture partnerships in order to share expertise, risk and resources for certain highly complex projects. The joint venture’s contract with the project owner typically requires joint and several liability among the joint venture partners. Although our agreements with our joint venture partners provide that each party will assume and fund its share of any losses resulting from a project, if one of our partners was unable to pay its share, we would be fully liable for such share under our contract with the project owner. Circumstances that could lead to a loss under these guarantee arrangements include a partner’s inability to contribute additional funds to the venture in the event that the project incurred a loss or additional costs that we could incur should the partner fail to provide the services and resources toward project completion that had been committed to in the joint venture agreement. See the 2020 Form 10-K under “Part I, Item 1A. Risk Factors”.
 At March 31, 2021, there was approximately $477 million of construction work to be completed on unconsolidated construction joint venture contracts, of which $206.1 million represented our proportionate share. Due to the joint and several liability under our joint venture arrangements, if one of our joint venture partners fails to perform, we and the remaining joint venture partners would be responsible for completion of the outstanding work. As of March 31, 2021, we are not aware of any situation that would require us to fulfill responsibilities of our joint venture partners pursuant to the joint and several liability under our contracts.
NEW ACCOUNTING STANDARDS
There have been no material changes to the Company’s discussion of new accounting standards from those described in Note 2 - Basis of Presentation and Significant Accounting Policies of our Annual Report on Form 10-K for the year ended December 31, 2020.
CRITICAL ACCOUNTING ESTIMATES
There have been no material changes to the Company’s discussion of critical accounting estimates from those described in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2020.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
Interest Rate Risk
We continue to utilize a swap arrangement to hedge against interest rate variability associated with $275 million of the $324.5 million outstanding under the Term Loan Facility. The Company has designated its interest rate swap agreement as a cash flow hedging derivative. To the extent the derivative instrument is effective and the documentation requirements have been met, changes in fair value are recognized in other comprehensive income (loss) until the underlying hedged item is recognized in earnings. The total fair value of the contract was a net loss of approximately $5.7 million at March 31, 2021. For the $49.5 million remaining portion of the Term Loan Facility not associated with the interest rate swap hedge, at March 31, 2021 a 100-basis point (or 1%) increase or decrease in the interest rate would increase or decrease interest expense by approximately $495 thousand per year.
Other
The carrying values of the Company’s cash and cash equivalents, accounts receivable and accounts payable approximate their fair values because of the short-term nature of these instruments. At March 31, 2021, the fair value of the term loan, based upon the current market rates for debt with similar credit risk and maturities, approximated its carrying value as interest is based on LIBOR plus an applicable margin.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures include, but are not limited to, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the issuer’s management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
The Company’s principal executive officer and principal financial officer reviewed and evaluated the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of March 31, 2021. Based on that evaluation, the Company’s principal executive officer and principal financial officer
24


concluded that the Company’s disclosure controls and procedures were effective at March 31, 2021 to ensure that the information required to be disclosed by the Company in this Report is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and is accumulated and communicated to the Company’s management including the principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended March 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitations on Effectiveness of Controls
Internal control over financial reporting may not prevent or detect all errors and all fraud. Also, projections of any evaluation of effectiveness of internal control to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
PART II—OTHER INFORMATION
Item 1. Legal Proceedings

In the opinion of management, after consultation with legal counsel, there are currently no threatened or pending legal matters that would reasonably be expected to have a material adverse impact on the Company’s Consolidated Results of Operations, Financial Position or Cash Flows.
Item 1A. Risk Factors
There have not been any material changes from the risk factors previously disclosed in “Part I, Item 1A. Risk Factors” of the 2020 Form 10-K. You should carefully consider such risk factors, which could materially affect the business, financial condition or future results.
