or &ldquo;the Company&rdquo;), a Delaware corporation, is a leading heavy civil construction company that specializes in the building
and reconstruction of transportation and water infrastructure projects in Texas, Utah, Nevada, Arizona, California, Hawaii and
other states in which there are profitable construction opportunities. Its transportation infrastructure projects include highways,
roads, bridges, airfields and light rail. Its water infrastructure projects include water, wastewater and storm drainage systems.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The condensed consolidated financial
statements included herein have been prepared by Sterling, without audit, in accordance with the rules and regulations of the Securities
and Exchange Commission (&ldquo;SEC&rdquo;) and should be read in conjunction with the 2014 Form 10-K. Certain information and
note disclosures prepared in accordance with generally accepted accounting principles (&ldquo;GAAP&rdquo;) have been either condensed
or omitted pursuant to SEC rules and regulations. The condensed consolidated financial statements reflect, in the opinion of management,
all normal recurring adjustments necessary to present fairly the Company&rsquo;s financial position at September 30, 2015 and the
results of operations and cash flows for the periods presented. The December 31, 2014 condensed consolidated balance sheet data
herein was derived from audited financial statements, but as discussed above, does not include all disclosures required by GAAP.
Interim results may be subject to significant seasonal variations, and the results of operations for the three and nine months
ended September 30, 2015 are not necessarily indicative of the results to be expected for the full year or subsequent quarters.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><I>Principles of Consolidation</I></P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The accompanying condensed consolidated
financial statements include the accounts of subsidiaries and construction joint ventures in which the Company has a greater than
50% ownership interest or otherwise controls such entities. For investments in subsidiaries and construction joint ventures that
are not wholly-owned, but where the Company exercises control, the equity held by the remaining owners and their portions of net
income (loss) are reflected in the balance sheet line item &ldquo;Noncontrolling interests&rdquo; in &ldquo;Equity&rdquo; and the
statement of operations line item &ldquo;Noncontrolling owners&rsquo; interests in earnings of subsidiaries,&rdquo; respectively.
All significant intercompany accounts and transactions have been eliminated in consolidation. For all years presented, the Company
had no subsidiaries where its ownership interests were less than 50%.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Where the Company is a noncontrolling joint
venture partner, and otherwise not required to consolidate the joint venture entity, its share of the operations of such construction
joint venture is accounted for on a pro rata basis in the condensed consolidated statements of operations and as a single line
item (&ldquo;Receivables from and equity in construction joint ventures&rdquo;) in the condensed consolidated balance sheets. This
method is an acceptable modification of the equity method of accounting which is a common practice in the construction industry.
Refer to Note 3<FONT STYLE="color: red"> </FONT>for further information regarding the Company&rsquo;s construction joint ventures.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Under U.S. GAAP, the Company must determine
whether each entity, including joint ventures in which it participates, is a variable interest entity (&ldquo;VIE&rdquo;). This
determination focuses on identifying which owner or joint venture partner, if any, has the power to direct the activities of the
entity and the obligation to absorb losses of the entity or the right to receive benefits from the entity disproportionate to its
interest in the entity, which could have the effect of requiring us to consolidate the entity in which we have a noncontrolling
variable interest. Refer to Note 10 for further information regarding the Company&rsquo;s consolidated VIE.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><I>Use of Estimates</I></P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The preparation of the accompanying condensed
consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions 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 of the Company&rsquo;s accounting policies
require higher degrees of judgment than others in their application. These include the recognition of revenue and earnings from
construction contracts under the percentage-of-completion method, the valuation of long-term assets (including goodwill), and income
taxes. Management continually evaluates all of its estimates and judgments based on available information and experience; however,
actual results could differ from these estimates.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><I>Reclassification</I></P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 2pt 0.05in 2pt 0">A reclassification has been made
to historical financial data on our condensed consolidated statement of cash flows to conform to our current year presentation.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><I>Revenue Recognition</I></P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company is a general contractor which
engages in various types of heavy civil construction projects principally for public (government) owners. Credit risk is minimal
with public owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing
work on such projects. While most public contracts are subject to termination at the election of the government entity, in the
event of termination the Company is entitled to receive the contract price for completed work and reimbursement of termination-related
costs. Credit risk with private owners is minimized because of statutory mechanic&rsquo;s liens, which give the Company high priority
in the event of lien foreclosures following financial difficulties of private owners.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Revenues are recognized on the percentage-of-completion
method, measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost
measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs
include all direct material, labor, subcontract and other costs and those indirect costs related to contract performance, such
as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses
are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such
losses are determined. 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.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Changes in estimated revenues and gross
margin resulted in a net charge of $1.1 million and $12.3 million during the three months and nine months ended September 30,
2015, respectively, included in Operating income (loss), or $(0.06) and $(0.64) per diluted share attributable to Sterling common
stockholders, respectively, included in Net income (loss) attributable to Sterling common stockholders. Changes in estimated revenues
and gross margin resulted in a net loss of $4.5 million and a net gain of $0.4 million during the three months and nine months
ended September 30, 2014, respectively, included in Operating income (loss), or $(0.24) and $0.02 per diluted share attributable
to Sterling common stockholders, respectively, included in Net income (loss) attributable to Sterling common stockholders.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our contracts generally take 12 to 36 months
to complete. The Company generally provides a one to two-year warranty for workmanship under its contracts when completed. Warranty
claims historically have been insignificant.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><I>Financial Instruments and Fair Value</I></P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The fair value of financial instruments
is the amount at which the instrument could be exchanged in a current transaction between willing parties. The Company&rsquo;s
financial instruments are cash and cash equivalents, restricted cash used as collateral for a letter of credit and restricted cash
maintained in an escrow account, short-term and long-term contracts receivable, derivatives, accounts payable, mortgage and notes
payable, a revolving loan (the &ldquo;Revolving Loan&rdquo;) with Nations Fund I, LLC and Nations Equipment Finance, LLC, as administrative
agent and collateral agent for the lender (&ldquo;Nations&rdquo;), a term loan (the &ldquo;Term Loan&rdquo;) with Nations, and
an earn-out liability related to the acquisition of J. Banicki Construction, Inc. (&ldquo;JBC&rdquo;).</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The recorded values of cash and
cash equivalents, and restricted cash, short-term contracts receivable and accounts payable approximate their fair values based
on their liquidity and/or short-term nature. The recorded value of long-term contracts receivable was based on the amount of future
cash flows discounted using the creditor&rsquo;s borrowing rate and such recorded value approximated fair value.</P>

    <!-- Field: /Page -->

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 0 0">The Company provides credit in the
normal course of business, principally to public (government) owners, and performs ongoing credit evaluations, as deemed necessary,
but generally does not require collateral to support such receivables.&nbsp; In an effort to reduce its credit exposure, as well
as accelerate its cash flows, in August 2015, the Company completed the sale, on a non-recourse basis, of its only long-term contract
receivable pursuant to a factoring agreement with a related party. The Company received approximately $7.1&nbsp;million upon the
closing of this transaction and recorded a loss of approximately $1.4 million in &ldquo;Other operating (expense) income, net.&rdquo;&nbsp;
As such, we did not have a long-term contract receivable at September 30, 2015. The long-term contract receivable was historically
discounted at 4.25% and recorded at fair value. Interest earned related to the long-term contract receivable was less than $0.1
million and $0.2 million for the three and nine months ended September 30, 2015, respectively, and $0.1 million and $0.3 million
for the three and nine months ended September 30, 2014, respectively.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Refer to Note 5 regarding the fair
value of derivatives, Note 8 regarding the fair value of an earn-out liability along with the most current amendments, and Note
12 regarding the fair value of the Revolving Loan and the Term Loan. The Company had one mortgage outstanding at December 31, 2014
with a remaining balance of $0.1 million and was fully paid in June 2015. At December 31, 2014, the fair value of the mortgage
approximated book value. The Company also has long-term notes payable of $2.5 million related to machinery and equipment purchased
which have payment terms ranging from 3 to 5 years and associated interest rates ranging from 3.12% to 6.29%. The fair value of
the notes payable approximates their book value. The Company does not have any off-balance sheet financial instruments other than
operating leases (refer to Note 14 of the Notes to Consolidated Financial Statements in the 2014 Form 10-K).</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0; background-color: white">In order
to assess the fair value of the Company&rsquo;s financial instruments, the Company uses the fair value hierarchy established by
GAAP which prioritizes the inputs used in valuation techniques into the following three levels:</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in">Level 1 Inputs &ndash; Based
upon quoted prices for identical assets in active markets that the Company has the ability to access at the measurement date.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in">Level 2 Inputs &ndash; Based
upon quoted prices (other than Level 1) in active markets for similar assets, quoted prices for identical or similar assets in
markets that are not active, inputs other than quoted prices that are observable for the asset such as interest rates, yield curves,
volatilities and default rates and inputs that are derived principally from or corroborated by observable market data.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in">Level 3 Inputs &ndash; Based
on unobservable inputs reflecting the Company&rsquo;s own assumptions about the assumptions that market participants would use
in pricing the asset based on the best information available.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">For each financial instrument, the
Company uses the highest priority level input that is available in order to appropriately value that particular instrument. In
certain instances, Level 1 inputs are not available and the Company must use Level 2 or Level 3 inputs. In these cases, the Company
provides a description of the valuation techniques used and the inputs used in the fair value measurement.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><I>Out-of-Period Adjustment</I></P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0">During the first quarter of 2015, the Company recorded
a $2.8 million out-of-period decrease in revenue that affected our results of operations for the nine months ended September 30,
2015. The adjustment was identified during our first quarter review of projects. Management evaluated the effect of the adjustment
on the Company&rsquo;s financial statements based on SEC Staff Accounting Bulletin (&ldquo;SAB&rdquo;) No. 99 and SAB 108 and concluded
that it was immaterial to the current and prior year&rsquo;s consolidated financial statements.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><I>Recent Accounting Pronouncements</I></P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In August 2015, the Financial Accounting
Standards Board (&ldquo;FASB&rdquo;) issued Accounting Standards Update (&ldquo;ASU&rdquo;) 2015-15, &ldquo;Presentation and Subsequent
Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements.&rdquo; The guidance, which incorporates the SEC
Staff Announcement at the June 18, 2015 EITF meeting and is effective upon announcement, provides clarification related to the
presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. The guidance states
that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing
the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding
borrowings on the line-of-credit arrangement. The Company is currently accounting for its debt issuance costs for its Term Loan

&ldquo;Inventory (Topic 330): Simplifying the Measurement of Inventory.&rdquo; The guidance, which is effective for annual reporting
periods beginning after December 15, 2016 and interim periods within those fiscal years, requires an entity to measure in scope
inventory at the lower of cost and net realizable value. Early adoption is permitted as of the beginning of an interim or annual
reporting period. Although early adoption is permitted, the Company expects to adopt this guidance as required and does not expect
a material impact to the Company&rsquo;s consolidated financial statements.</P>

- Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.&rdquo; The guidance, which is effective for annual
reporting periods beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2015,
requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction
from the carrying amount of that debt liability, consistent with debt discounts. The adoption of this ASU requires retrospective
application to all periods presented. Although early adoption is permitted, the Company expects to adopt this guidance as required
and expects a change in the presentation of our consolidated balance sheets and related disclosures. The Company does not expect
a material impact to the consolidated statements of operations.</P>

&ldquo;Consolidation: Amendments to the Consolidation Analysis.&rdquo; The guidance, which is effective for annual reporting periods
beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2015, modifies the analysis
that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. Early adoption
is permitted. The Company does not expect a material impact to the Company&rsquo;s consolidated financial statements and related
disclosures.</P>

reporting periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016, requires
management to evaluate whether there is substantial doubt about the entity&rsquo;s ability to continue as a going concern and to
provide related footnote disclosures. Early adoption is permitted. Although early adoption is permitted, the Company expects to
adopt this guidance as required and does not expect a material impact to the Company&rsquo;s consolidated financial statements.</P>

2014-09, &ldquo;Revenue from Contracts with Customers.&rdquo; The guidance defines the steps to recognize revenue for entities
that have contracts with customers. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09
by one year. As a result, the amendments in ASU 2014-09 are effective for public companies for annual reporting periods beginning
after December 15, 2017, including interim periods within that reporting period. Entities would be permitted to adopt this ASU
as early as the original public entity effective date, which was annual reporting periods beginning after December 15, 2016 and
interim periods therein. Early adoption prior to that date would not be permitted.&nbsp; The Company is currently evaluating the
impact of the adoption of this ASU to the Company&rsquo;s consolidated financial statements and related disclosures.</P>

Richard Buenting revised the Second Amended and Restated Operating Agreement entered into on April 27, 2012 and their Management
Agreement entered into on February 1, 2012. The Third Amended and Restated Operating Agreement and the amended Management Agreement
eliminated the buy/sell option and instead included the obligation for the Company to purchase Mr. Buenting&rsquo;s interest upon
his death or permanent disability for $20 million or $18 million, respectively. In the event of Mr. Buenting&rsquo;s death or permanent
disability, his estate representative, trustee or designee shall become the selling representative and sell his 50% interest to
the Company. In order to fund the purchase of Mr. Buenting&rsquo;s interest, the Company has purchased term life insurance with
a payout of $20 million in the event of Mr. Buenting&rsquo;s death. The Company will be the beneficiary and will also pay the premiums
related to this life insurance contract. The life insurance proceeds of $20 million shall be used as full payment for Mr. Buenting&rsquo;s
interest in the occurrence of his death. On June 2, 2015, the Company purchased an insurance policy with a five-year term on Mr.
Buenting that provides a lump sum disability benefit in the principal sum of $20 million. &nbsp;In the event of Mr. Buenting&rsquo;s

of the policy to purchase Mr. Buenting&rsquo;s 50% member&rsquo;s interest in RHB in accordance with the terms of the amended agreements.
No other transfer of member&rsquo;s interest is permitted other than to the selling representative in the event of Mr. Buenting&rsquo;s
death or permanent disability. In the event that Mr. Buenting resigns his 50% interest in RHB or is terminated without cause (i.e.,
termination other than through cause, permanent disability or death), RHB shall be dissolved unless both members agree otherwise.
The amended agreements were entered into in order to eliminate the earnings-per-share volatility caused by the buy/sell option.</P>

30, 2015, the Company entered into two agreements, one with RHB and one with Myers, which gives the 50% owners of these entities

would ever transpire; therefore, there has been no value placed on these options which resulted in no impact to our condensed consolidated
financial statements. Refer to Note 12 for more information about the debt agreement with Nations.</P>

2011, acquisition of JBC by Ralph L. Wadsworth Construction Company, LLC (&ldquo;RLW&rdquo;), RLW agreed to additional purchase
price payments of up to $5 million to be paid over a five-year period. The additional purchase price is in the form of an earn-out
and is classified as a Level 3 fair value measurement. In making this valuation, the unobservable input consisted of forecasted
EBITDA for the periods after the period being reported on through July 31, 2016. The additional purchase price is calculated generally
as 50% of the amount by which EBITDA exceeds $2.0 million for each of the calendar years 2011 through 2015 and $1.2 million for
the seven months ended July 31, 2016.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">On January 23, 2014, RLW, the former
owner of JBC and the Company agreed to amend the above mentioned earn-out agreement in order to reduce the Company&rsquo;s recorded
liability at that time, while providing the former owner, who at the time was the chief executive officer of JBC, a greater incentive
to meet earnings benchmarks. The amendment resulted in a reduction of $0.6 million in the Company&rsquo;s earn-out liability, thereby
reducing the total earn-out liability to $1.4 million on December 31, 2013. As part of the amendment, a payment of $0.8 million
was made during the first quarter of 2014. The amendment increased the total available earn-out from $5.0 million to $10.0 million
if certain EBITDA benchmarks are met. The amendment extended the earn-out period through December 31, 2017 and reduced the benchmark
EBITDA for 2014 and 2015 to $1.5 million and increased it to $2.0 million in 2016 and 2017. This earn-out liability continues to
be classified as a Level 3 fair value measurement and the unobservable inputs continue to be the forecasted EBITDA for the periods
after the period being reported on through December 31, 2017. There was no yearly excess forecasted EBITDA in our calculation at
September 30, 2015 of the minimum EBITDA benchmarks for the years 2015 through 2017. The discounted present value of the additional
purchase price was estimated to be $0.3 million as of September 30, 2014 which included a revaluation benefit of $0.3 million recorded
in interest income on the condensed consolidated statement of operations. The undiscounted earn-out liability as of September 30,
2015 is estimated at zero and could increase by $9.3 million if EBITDA during the earn-out period increases $18.5 million or more
and could decrease by the full amount of the liability for the year if EBITDA does not exceed the minimum threshold for that year.
Each year is considered a discrete earnings period and future losses by JBC, if any, would not reduce the Company&rsquo;s liability
in years in which JBC has exceeded its earnings benchmark. Any significant increase or decrease in actual EBITDA compared to the
forecasted amounts would result in a significantly higher or lower fair value measurement of the additional purchase price. This
liability is included in other long-term liabilities on the accompanying condensed consolidated balance sheets. As part of recording
the present value of this liability, the Company incurs accreted interest expense for the passage of time until the time of settlement.
The Company incurred accreted interest expense of zero and $0.3 million for the three months and nine months ended September 30,
2014, respectively. As part of the updated EBITDA forecast, the Company reduced its liability to zero and recorded interest income
of $0.3 million in the first quarter of 2015. There has been no change in the value of this liability; therefore, the interest
income was zero and $0.3 million for the three and nine months ended September 30, 2015, respectively.</P>

plan which is administered by the Compensation Committee of the Board of Directors. Refer to Note 16 of the Notes to Consolidated
Financial Statements included in the 2014 Form 10-K for further information. The Company recorded stock-based compensation expense
of $0.8 million and $1.3 million for the three and nine months ended September 30, 2015, respectively, and $0.2 million and $0.6

compensation cost related to unvested common stock awards was $3.0 million. This cost is expected to be recognized over a weighted
average period of 2.0 years. There was no unrecognized compensation expense related to stock options at September 30, 2015 and
2014. There were no proceeds received by the Company from the exercise of stock options for the three and nine months ended September
30, 2015 and such proceeds were immaterial for the three and nine months ended September 30, 2014. No stock options were granted
in the three or nine months ended September 30, 2015 or 2014. At September 30, 2015, there were 0.8 million shares of common stock
covered by outstanding unvested common stock.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">On January 1, 2015, the Company
launched a long- and short-term incentive program for certain employees. The short-term incentive plan is paid in cash if certain
short-term achievements are met and the long-term incentive plan is paid with the Company&rsquo;s stock if certain long-term achievements
are met. The stock based awards are awarded based in two parts; 50% is based on completing a service period of three years and
50% is based on the level of achievement of the Company&rsquo;s total shareholder return (&ldquo;TSR&rdquo;) compared to the TSR
of a designated peer group over a three year period. The service based awards are recorded as usual; however, the awards based
on TSR must be valued using a Monte Carlo simulation. Based on the valuation obtained using Monte Carlo simulation and valuation
on the service based awards, the Company recorded an expense of $0.1 million and $0.3 million, which was included in the $0.8 million
and $1.3 million expense mentioned above, for the three and nine months ended September 30, 2015, respectively.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">On March 9, 2015, the Company entered
into a three-year employment agreement with Paul J. Varello, the Company&rsquo;s Chief Executive Officer (&ldquo;CEO&rdquo;). As
part of the agreement, Mr. Varello will be paid an annual salary of $1 and received 600,000 shares of the Company&rsquo;s common
stock which vest in three equal installments on the first three anniversaries of the March 9, 2015 award date. The award is a special
one-time plan for the CEO and was approved by the Company&rsquo;s stockholders at its 2015 Annual Meeting in May 2015 and was valued
at approximately $2.5 million.</P>

wholly-owned subsidiaries entered into a $40.0 million loan and security agreement with Nations, consisting of a $20.0 million
Term Loan and a $20.0 million Revolving Loan (combined, the &ldquo;Equipment-based Facility&rdquo;), which replaced its prior credit
facility with Comerica (&ldquo;Prior Credit Facility&rdquo;). The amount of the Revolving Loan that may be borrowed from time to
time is determined quarterly and may not exceed $20.0 million. In addition, the sum of the outstanding balances of the Equipment-based
Facility may not exceed the lesser of $40.0 million or 65% of the appraised value of the collateral pledged for the loans. At September
30, 2015, the Company had approximately $34.3 million of borrowing base which was the result of calculating 65% of the appraised
value (where appraised value equals net operating liquidated value) of the Company&rsquo;s collateral. The Revolving Loan may be
utilized by the Company to provide ongoing working capital and for other general corporate purposes. At September 30, 2015, the
Company had $13.1 million drawn on the Revolving Loan, $19.0 million Term Loan outstanding and $2.2 million of borrowings available.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The Equipment-based Facility bears
interest at an initial fixed annual rate of 12%, which is subject to (i) a decrease of up to two percentage points based on the
Company's fixed charge coverage ratio for each of the most recently ended four quarters beginning with the four quarters ended
June 30, 2016; and (ii) an increase of two percentage points beginning December 31, 2015 based on the fixed charge coverage ratio
at the end of the following two quarters. Principal on the Term Loan is payable in 47 monthly installments (with accrued interest)
with a final payment of the then outstanding principal amount on May 29, 2019. Up to $5.0 million of the Term Loan may be prepaid
in any year, but subject to a pre-payment fee that declines as the Term Loan nears maturity. Outstanding Revolving Loans are payable
in full thirty days before the maturity date of the Term Loan.</P>

of the Company's 50%-owned affiliates, Road and Highway Builders, LLC and Myers &amp; Sons Construction, L.P. pursuant to a separate
security agreement with those entities. If a default occurs, Nations may exercise the Company's rights in the collateral, with

at public or private sale.</P>

$20.0 million and our initial draw of $14.6 million under the Revolving Loan were utilized by the Company to repay the balance

this debt, we recorded $1.3 million in deferred debt issuance costs which are included in &ldquo;Other assets, net&rdquo; in our
condensed consolidated balance sheet, which is being amortized over the term of the Equipment-based Facility.</P>

extinguish this Prior Credit Facility debt, the Company incurred costs of $0.2 million which is included in the Company&rsquo;s

made announcements regarding the Company&rsquo;s earnings and noncompliance with one of our Prior Credit Facility covenants. On
January 27, 2015, the Company announced its preliminary fourth quarter and full year 2014 results and that the Company was not
in compliance with the Prior Credit Facility&rsquo;s tangible net worth covenant. On March 16, 2015, the Company announced actual
fourth quarter and full year 2014 results and that a waiver of the covenant breach had been obtained. As a result of these announcements,
the Company&rsquo;s stock price fluctuated greatly during the first quarter of 2015, dropping from a January 2<SUP>nd</SUP> price

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Due to the decrease in the stock price
that resulted and our first quarter loss, the Company noted that a goodwill impairment triggering event occurred during the first
quarter of 2015. Therefore, we updated our fourth quarter goodwill impairment assessment using the two methods discussed in Note
8 of the Notes to Consolidated Financial Statements in the 2014 Form 10-K. The assessment used updated first quarter information
which incorporated the Company&rsquo;s stock price at March 31, 2015 and reduced gross margins used in our discounted cash flow
model projections. Based on this revised testing, there was no goodwill impairment and we determined that the fair value of the
Company&rsquo;s equity was approximately 8% above the carrying value of the Company&rsquo;s equity.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">During the third quarter of 2015, the Company
noted that the revenue projections used in our first quarter goodwill impairment assessment were higher than our actual results
for the second and third quarters of 2015; therefore, the Company determined that a goodwill impairment triggering event occurred
during the third quarter of 2015. As such, we updated our first quarter goodwill impairment assessment with third quarter 2015
information which incorporated the Company&rsquo;s stock price at September 30, 2015 and reduced the projected revenue used in
our discounted cash flow model. The forecasted cash flows took into consideration historical and recent results, backlog and near
term projects, recent developments, strategic actions and management&rsquo;s outlook for the future. The forecast and growth assumptions
included, among other things, improved project performance, continuation of a strong base market, and margin improvements driven
by incremental margin product opportunities and pursuing work in adjacent markets. Based on this revised testing, there was no
goodwill impairment and we passed by an improved margin compared to that of our first quarter&rsquo;s 2015 assessment margin.</P>

<P STYLE="font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our third quarter goodwill impairment assessment&rsquo;s
concluded fair value could be negatively impacted if actual future performance falls short of the collective cash flow model assumptions
or if our stock price is adversely affected. If based on future assessments, our goodwill is deemed to be impaired; the impairment
would result in a charge to earnings which could be material.</P>

The amount of the Revolving Loan that may be borrowed from time to time is determined quarterly and may not exceed $20.0 million. In addition, the sum of the outstanding balances of the Equipment-based Facility may not exceed the lesser of $40.0 million or 65% of the appraised value of the collateral pledged for the loans. At September 30, 2015, the Company had approximately $34.3 million of borrowing base which was the result of calculating 65% of the appraised value (where appraised value equals net operating liquidated value) of the Company&amp;#x2019;s collateral. The Revolving Loan may be utilized by the Company to provide ongoing working capital and for other general corporate purposes.

Principal on the Term Loan is payable in 47 monthly installments (with accrued interest) with a final payment of the then outstanding principal amount on May 29, 2019. Up to $5.0 million of the Term Loan may be prepaid in any year, but subject to a pre-payment fee that declines as the Term Loan nears maturity.

The Company&amp;#x2019;s financial instruments are cash and cash equivalents, restricted cash used as collateral for a letter of credit and restricted cash maintained in an escrow account, short-term and long-term contracts receivable, derivatives, accounts payable, mortgage and notes payable, a revolving loan (the &amp;#x201c;Revolving Loan&amp;#x201d;) with Nations Fund I, LLC and Nations Equipment Finance, LLC, as administrative agent and collateral agent for the lender (&amp;#x201c;Nations&amp;#x201d;), a term loan (the &amp;#x201c;Term Loan&amp;#x201d;) with Nations, and an earn-out liability related to the acquisition of J.

The Company received approximately $7.1&amp;nbsp;million upon the closing of this transaction and recorded a loss of approximately $1.4 million in &amp;#x201c;Other operating (expense) income, net.&amp;#x201d;&amp;nbsp; As such, we did not have a long-term contract receivable at September 30, 2015. The long-term contract receivable was historically discounted at 4.25% and recorded at fair value. Interest earned related to the long-term contract receivable was less than $0.1 million and $0.2 million for the three and nine months ended September 30, 2015, respectively, and $0.1 million and $0.3 million for the three and nine months ended September 30, 2014, respectively.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;Refer to Note 5 regarding the fair value of derivatives, Note 8 regarding the fair value of an earn-out liability along with the most current amendments, and Note 12 regarding the fair value of the Revolving Loan and the Term Loan. The Company had one mortgage outstanding at December 31, 2014 with a remaining balance of $0.1 million and was fully paid in June 2015. At December 31, 2014, the fair value of the mortgage approximated book value. The Company also has long-term notes payable of $2.5 million related to machinery and equipment purchased which have payment terms ranging from 3 to 5 years and associated interest rates ranging from 3.12% to 6.29%. The fair value of the notes payable approximates their book value. The Company does not have any off-balance sheet financial instruments other than operating leases (refer to Note 14 of the Notes to Consolidated Financial Statements in the 2014 Form 10-K).&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0; background-color: white"&gt;In order to assess the fair value of the Company&amp;#x2019;s financial instruments, the Company uses the fair value hierarchy established by GAAP which prioritizes the inputs used in valuation techniques into the following three levels:&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in"&gt;Level 1 Inputs &amp;#x2013; Based upon quoted prices for identical assets in active markets that the Company has the ability to access at the measurement date.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in"&gt;Level 2 Inputs &amp;#x2013; Based upon quoted prices (other than Level 1) in active markets for similar assets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset such as interest rates, yield curves, volatilities and default rates and inputs that are derived principally from or corroborated by observable market data.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in"&gt;Level 3 Inputs &amp;#x2013; Based on unobservable inputs reflecting the Company&amp;#x2019;s own assumptions about the assumptions that market participants would use in pricing the asset based on the best information available.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;For each financial instrument, the Company uses the highest priority level input that is available in order to appropriately value that particular instrument.

On January 27, 2015, the Company announced its preliminary fourth quarter and full year 2014 results and that the Company was not in compliance with the Prior Credit Facility&amp;#x2019;s tangible net worth covenant. On March 16, 2015, the Company announced actual fourth quarter and full year 2014 results and that a waiver of the covenant breach had been obtained. As a result of these announcements, the Company&amp;#x2019;s stock price fluctuated greatly during the first quarter of 2015, dropping from a January 2&lt;div style="display: inline; bottom:.33em; font-size: 82%; position: relative; vertical-align: baseline;"&gt;nd&lt;/div&gt; price of $6.41 to a March 31&lt;div style="display: inline; bottom:.33em; font-size: 82%; position: relative; vertical-align: baseline;"&gt;st&lt;/div&gt; price of $4.52.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 19 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Due to the decrease in the stock price that resulted and our first quarter loss, the Company noted that a goodwill impairment triggering event occurred during the first quarter of 2015. Therefore, we updated our fourth quarter goodwill impairment assessment using the two methods discussed in Note 8 of the Notes to Consolidated Financial Statements in the 2014 Form 10-K. The assessment used updated first quarter information which incorporated the Company&amp;#x2019;s stock price at March 31, 2015 and reduced gross margins used in our discounted cash flow model projections. Based on this revised testing, there was no goodwill impairment and we determined that the fair value of the Company&amp;#x2019;s equity was approximately 8% above the carrying value of the Company&amp;#x2019;s equity.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;During the third quarter of 2015, the Company noted that the revenue projections used in our first quarter goodwill impairment assessment were higher than our actual results for the second and third quarters of 2015; therefore, the Company determined that a goodwill impairment triggering event occurred during the third quarter of 2015. As such, we updated our first quarter goodwill impairment assessment with third quarter 2015 information which incorporated the Company&amp;#x2019;s stock price at September 30, 2015 and reduced the projected revenue used in our discounted cash flow model. The forecasted cash flows took into consideration historical and recent results, backlog and near term projects, recent developments, strategic actions and management&amp;#x2019;s outlook for the future. The forecast and growth assumptions included, among other things, improved project performance, continuation of a strong base market, and margin improvements driven by incremental margin product opportunities and pursuing work in adjacent markets. Based on this revised testing, there was no goodwill impairment and we passed by an improved margin compared to that of our first quarter&amp;#x2019;s 2015 assessment margin.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Our third quarter goodwill impairment assessment&amp;#x2019;s concluded fair value could be negatively impacted if actual future performance falls short of the collective cash flow model assumptions or if our stock price is adversely affected. If based on future assessments, our goodwill is deemed to be impaired; the impairment would result in a charge to earnings which could be material.&lt;/div&gt;&lt;/div&gt;</us-gaap:GoodwillDisclosureTextBlock>

The Company does expect a state tax liability for 2015 in states without sufficient net operating loss carry forwards. This state tax expense has been offset with a state tax benefit related to a prior year. Therefore, a net current tax benefit has been recorded for those states for the three and nine months ended September 30, 2015.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 0 0"&gt;The Company&amp;#x2019;s deferred tax expense or (benefit) reflects the change in deferred tax assets or liabilities. The Company performs an analysis at the end of each reporting period to determine whether it is more likely than not the deferred tax assets are expected to be realized in future years. Based upon this analysis, a valuation allowance has been applied to our net deferred tax assets as of September 30, 2015 and December 31, 2014. Therefore, there has been no change in net deferred taxes for the three and nine months ended September 30, 2015.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 13 --&gt;    &lt;div style="page-break-before: always;

The Third Amended and Restated Operating Agreement and the amended Management Agreement eliminated the buy/sell option and instead included the obligation for the Company to purchase Mr. Buenting&amp;#x2019;s interest upon his death or permanent disability for $20 million or $18 million, respectively. In the event of Mr. Buenting&amp;#x2019;s death or permanent disability, his estate representative, trustee or designee shall become the selling representative and sell his 50% interest to the Company. In order to fund the purchase of Mr. Buenting&amp;#x2019;s interest, the Company has purchased term life insurance with a payout of $20 million in the event of Mr. Buenting&amp;#x2019;s death. The Company will be the beneficiary and will also pay the premiums related to this life insurance contract. The life insurance proceeds of $20 million shall be used as full payment for Mr. Buenting&amp;#x2019;s interest in the occurrence of his death. On June 2, 2015, the Company purchased an insurance policy with a five-year term on Mr. Buenting that provides a lump sum disability benefit in the principal sum of $20 million. &amp;nbsp;In the event of Mr. Buenting&amp;#x2019;s permanent total disability, the principal sum becomes payable to the Company, and in turn the Company is obligated to use the proceeds of the policy to purchase Mr. Buenting&amp;#x2019;s 50% member&amp;#x2019;s interest in RHB in accordance with the terms of the amended agreements. No other transfer of member&amp;#x2019;s interest is permitted other than to the selling representative in the event of Mr. Buenting&amp;#x2019;s death or permanent disability. In the event that Mr. Buenting resigns his 50% interest in RHB or is terminated without cause (i.e., termination other than through cause, permanent disability or death), RHB shall be dissolved unless both members agree otherwise. The amended agreements were entered into in order to eliminate the earnings-per-share volatility caused by the buy/sell option.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 14 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 0 0"&gt;The amended agreements resulted in an obligation to purchase Mr. Buenting&amp;#x2019;s 50% member&amp;#x2019;s interest that the Company is certain to incur, either because of Mr. Buenting&amp;#x2019;s permanent disability or death; therefore, the Company has classified the noncontrolling interest as mandatorily redeemable and has recorded a liability in &amp;#x201c;Member&amp;#x2019;s interest subject to mandatory redemption and undistributed earnings&amp;#x201d; on the condensed consolidated balance sheets.

for the three and nine months ended September 30, 2015 and 2014, shown in the accompanying condensed consolidated statements of operations, was $1.1 million and $2.9 million, respectively, and $1.7 million and $3.2 million, respectively, which the Company includes in &amp;#x201c;Equity&amp;#x201d;, &amp;#x201c;Noncontrolling interests&amp;#x201d; in the accompanying condensed consolidated balance sheets. There was a distribution of $1.0 million and $3.4 million to certain noncontrolling interest members during the three and nine months ended September 30, 2015 and there were no distributions and distributions of $1.2 million during the three and nine months ended September 30, 2014, respectively.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Noncontrolling Interests&amp;#x2019; &amp;#x2013; Call Options&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0 0.05in 0 0"&gt;During the nine months ended September 30, 2015, the Company entered into two agreements, one with RHB and one with Myers, which gives the 50% owners of these entities the option to buy the Company&amp;#x2019;s 50% interest in these entities for $1.00 should the Company ever become subject to the repossession or disposition of its collateral as defined in the Company&amp;#x2019;s new debt agreement with Nations or if the Company dissolves or becomes insolvent. Based on these agreements, the Company does not believe that it is likely that the exercise of these options would ever transpire; therefore, there has been no value placed on these options which resulted in no impact to our condensed consolidated financial statements. Refer to Note 12 for more information about the debt agreement with Nations.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Earn-out Agreement&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;In connection with the August 1, 2011, acquisition of JBC by Ralph L. Wadsworth Construction Company, LLC (&amp;#x201c;RLW&amp;#x201d;), RLW agreed to additional purchase price payments of up to $5 million to be paid over a five-year period. The additional purchase price is in the form of an earn-out and is classified as a Level 3 fair value measurement. In making this valuation, the unobservable input consisted of forecasted EBITDA for the periods after the period being reported on through July 31, 2016. The additional purchase price is calculated generally as 50% of the amount by which EBITDA exceeds $2.0 million for each of the calendar years 2011 through 2015 and $1.2 million for the seven months ended July 31, 2016.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 15 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;On January 23, 2014, RLW, the former owner of JBC and the Company agreed to amend the above mentioned earn-out agreement in order to reduce the Company&amp;#x2019;s recorded liability at that time, while providing the former owner, who at the time was the chief executive officer of JBC, a greater incentive to meet earnings benchmarks. The amendment resulted in a reduction of $0.6 million in the Company&amp;#x2019;s earn-out liability, thereby reducing the total earn-out liability to $1.4 million on December 31, 2013. As part of the amendment, a payment of $0.8 million was made during the first quarter of 2014. The amendment increased the total available earn-out from $5.0 million to $10.0 million if certain EBITDA benchmarks are met. The amendment extended the earn-out period through December 31, 2017 and reduced the benchmark EBITDA for 2014 and 2015 to $1.5 million and increased it to $2.0 million in 2016 and 2017. This earn-out liability continues to be classified as a Level 3 fair value measurement and the unobservable inputs continue to be the forecasted EBITDA for the periods after the period being reported on through December 31, 2017. There was no yearly excess forecasted EBITDA in our calculation at September 30, 2015 of the minimum EBITDA benchmarks for the years 2015 through 2017. The discounted present value of the additional purchase price was estimated to be $0.3 million as of September 30, 2014 which included a revaluation benefit of $0.3 million recorded in interest income on the condensed consolidated statement of operations. The undiscounted earn-out liability as of September 30, 2015 is estimated at zero and could increase by $9.3 million if EBITDA during the earn-out period increases $18.5 million or more and could decrease by the full amount of the liability for the year if EBITDA does not exceed the minimum threshold for that year. Each year is considered a discrete earnings period and future losses by JBC, if any, would not reduce the Company&amp;#x2019;s liability in years in which JBC has exceeded its earnings benchmark. Any significant increase or decrease in actual EBITDA compared to the forecasted amounts would result in a significantly higher or lower fair value measurement of the additional purchase price. This liability is included in other long-term liabilities on the accompanying condensed consolidated balance sheets. As part of recording the present value of this liability, the Company incurs accreted interest expense for the passage of time until the time of settlement. The Company incurred accreted interest expense of zero and $0.3 million for the three months and nine months ended September 30, 2014, respectively. As part of the updated EBITDA forecast, the Company reduced its liability to zero and recorded interest income of $0.3 million in the first quarter of 2015. There has been no change in the value of this liability; therefore, the interest income was zero and $0.3 million for the three and nine months ended September 30, 2015, respectively.&lt;/div&gt;&lt;/div&gt;</us-gaap:MinorityInterestDisclosureTextBlock>

The guidance states that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company is currently accounting for its debt issuance costs for its Term Loan and line-of-credit Revolver Loan in this manner and would only expect a change in presentation of the deferred amounts related to the Term Loan upon adoption as required by ASU 2015-03.

Early adoption is permitted as of the beginning of an interim or annual reporting period. Although early adoption is permitted, the Company expects to adopt this guidance as required and does not expect a material impact to the Company&amp;#x2019;s consolidated financial statements.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In April 2015, the FASB issued ASU 2015-03, &amp;#x201c;Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.&amp;#x201d; The guidance, which is effective for annual reporting periods beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2015, requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The adoption of this ASU requires retrospective application to all periods presented. Although early adoption is permitted, the Company expects to adopt this guidance as required and expects a change in the presentation of our consolidated balance sheets and related disclosures.

In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 by one year. As a result, the amendments in ASU 2014-09 are effective for public companies for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Entities would be permitted to adopt this ASU as early as the original public entity effective date, which was annual reporting periods beginning after December 15, 2016 and interim periods therein. Early adoption prior to that date would not be permitted.&amp;nbsp; The Company is currently evaluating the impact of the adoption of this ASU to the Company&amp;#x2019;s consolidated financial statements and related disclosures.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

For investments in subsidiaries and construction joint ventures that are not wholly-owned, but where the Company exercises control, the equity held by the remaining owners and their portions of net income (loss) are reflected in the balance sheet line item &amp;#x201c;Noncontrolling interests&amp;#x201d; in &amp;#x201c;Equity&amp;#x201d; and the statement of operations line item &amp;#x201c;Noncontrolling owners&amp;#x2019; interests in earnings of subsidiaries,&amp;#x201d; respectively.

This determination focuses on identifying which owner or joint venture partner, if any, has the power to direct the activities of the entity and the obligation to absorb losses of the entity or the right to receive benefits from the entity disproportionate to its interest in the entity, which could have the effect of requiring us to consolidate the entity in which we have a noncontrolling variable interest.

Certain of the Company&amp;#x2019;s accounting policies require higher degrees of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts under the percentage-of-completion method, the valuation of long-term assets (including goodwill), and income taxes. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Reclassification&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 2pt 0.05in 2pt 0"&gt;A reclassification has been made to historical financial data on our condensed consolidated statement of cash flows to conform to our current year presentation.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Revenue Recognition&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;The Company is a general contractor which engages in various types of heavy civil construction projects principally for public (government) owners. Credit risk is minimal with public owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing work on such projects. While most public contracts are subject to termination at the election of the government entity, in the event of termination the Company is entitled to receive the contract price for completed work and reimbursement of termination-related costs. Credit risk with private owners is minimized because of statutory mechanic&amp;#x2019;s liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Revenues are recognized on the percentage-of-completion method, measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs related to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. 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.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Changes in estimated revenues and gross margin resulted in a net charge of $1.1 million and $12.3 million during the three months and nine months ended September 30, 2015, respectively, included in Operating income (loss), or $(0.06) and $(0.64) per diluted share attributable to Sterling common stockholders, respectively, included in Net income (loss) attributable to Sterling common stockholders.

The Company&amp;#x2019;s financial instruments are cash and cash equivalents, restricted cash used as collateral for a letter of credit and restricted cash maintained in an escrow account, short-term and long-term contracts receivable, derivatives, accounts payable, mortgage and notes payable, a revolving loan (the &amp;#x201c;Revolving Loan&amp;#x201d;) with Nations Fund I, LLC and Nations Equipment Finance, LLC, as administrative agent and collateral agent for the lender (&amp;#x201c;Nations&amp;#x201d;), a term loan (the &amp;#x201c;Term Loan&amp;#x201d;) with Nations, and an earn-out liability related to the acquisition of J.

The Company received approximately $7.1&amp;nbsp;million upon the closing of this transaction and recorded a loss of approximately $1.4 million in &amp;#x201c;Other operating (expense) income, net.&amp;#x201d;&amp;nbsp; As such, we did not have a long-term contract receivable at September 30, 2015. The long-term contract receivable was historically discounted at 4.25% and recorded at fair value. Interest earned related to the long-term contract receivable was less than $0.1 million and $0.2 million for the three and nine months ended September 30, 2015, respectively, and $0.1 million and $0.3 million for the three and nine months ended September 30, 2014, respectively.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;Refer to Note 5 regarding the fair value of derivatives, Note 8 regarding the fair value of an earn-out liability along with the most current amendments, and Note 12 regarding the fair value of the Revolving Loan and the Term Loan. The Company had one mortgage outstanding at December 31, 2014 with a remaining balance of $0.1 million and was fully paid in June 2015. At December 31, 2014, the fair value of the mortgage approximated book value. The Company also has long-term notes payable of $2.5 million related to machinery and equipment purchased which have payment terms ranging from 3 to 5 years and associated interest rates ranging from 3.12% to 6.29%. The fair value of the notes payable approximates their book value. The Company does not have any off-balance sheet financial instruments other than operating leases (refer to Note 14 of the Notes to Consolidated Financial Statements in the 2014 Form 10-K).&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0; background-color: white"&gt;In order to assess the fair value of the Company&amp;#x2019;s financial instruments, the Company uses the fair value hierarchy established by GAAP which prioritizes the inputs used in valuation techniques into the following three levels:&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in"&gt;Level 1 Inputs &amp;#x2013; Based upon quoted prices for identical assets in active markets that the Company has the ability to access at the measurement date.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in"&gt;Level 2 Inputs &amp;#x2013; Based upon quoted prices (other than Level 1) in active markets for similar assets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset such as interest rates, yield curves, volatilities and default rates and inputs that are derived principally from or corroborated by observable market data.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in"&gt;Level 3 Inputs &amp;#x2013; Based on unobservable inputs reflecting the Company&amp;#x2019;s own assumptions about the assumptions that market participants would use in pricing the asset based on the best information available.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;For each financial instrument, the Company uses the highest priority level input that is available in order to appropriately value that particular instrument. In certain instances, Level 1 inputs are not available and the Company must use Level 2 or Level 3 inputs. In these cases, the Company provides a description of the valuation techniques used and the inputs used in the fair value measurement.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Out-of-Period Adjustment&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0"&gt;During the first quarter of 2015, the Company recorded a $2.8 million out-of-period decrease in revenue that affected our results of operations for the nine months ended September 30, 2015. The adjustment was identified during our first quarter review of projects. Management evaluated the effect of the adjustment on the Company&amp;#x2019;s financial statements based on SEC Staff Accounting Bulletin (&amp;#x201c;SAB&amp;#x201d;) No. 99 and SAB 108 and concluded that it was immaterial to the current and prior year&amp;#x2019;s consolidated financial statements.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Recent Accounting Pronouncements&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In August 2015, the Financial Accounting Standards Board (&amp;#x201c;FASB&amp;#x201d;) issued Accounting Standards Update (&amp;#x201c;ASU&amp;#x201d;) 2015-15, &amp;#x201c;Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements.&amp;#x201d; The guidance, which incorporates the SEC Staff Announcement at the June 18, 2015 EITF meeting and is effective upon announcement, provides clarification related to the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. The guidance states that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company is currently accounting for its debt issuance costs for its Term Loan and line-of-credit Revolver Loan in this manner and would only expect a change in presentation of the deferred amounts related to the Term Loan upon adoption as required by ASU 2015-03. See below for the discussion related to ASU 2015-03.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 10 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In July 2015, the FASB issued ASU 2015-11, &amp;#x201c;Inventory (Topic 330): Simplifying the Measurement of Inventory.&amp;#x201d; The guidance, which is effective for annual reporting periods beginning after December 15, 2016 and interim periods within those fiscal years, requires an entity to measure in scope inventory at the lower of cost and net realizable value. Early adoption is permitted as of the beginning of an interim or annual reporting period. Although early adoption is permitted, the Company expects to adopt this guidance as required and does not expect a material impact to the Company&amp;#x2019;s consolidated financial statements.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In April 2015, the FASB issued ASU 2015-03, &amp;#x201c;Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.&amp;#x201d; The guidance, which is effective for annual reporting periods beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2015, requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The adoption of this ASU requires retrospective application to all periods presented. Although early adoption is permitted, the Company expects to adopt this guidance as required and expects a change in the presentation of our consolidated balance sheets and related disclosures. The Company does not expect a material impact to the consolidated statements of operations.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;In February 2015, the FASB issued ASU 2015-02, &amp;#x201c;Consolidation: Amendments to the Consolidation Analysis.&amp;#x201d; The guidance, which is effective for annual reporting periods beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2015, modifies the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. Early adoption is permitted.

In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 by one year. As a result, the amendments in ASU 2014-09 are effective for public companies for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Entities would be permitted to adopt this ASU as early as the original public entity effective date, which was annual reporting periods beginning after December 15, 2016 and interim periods therein. Early adoption prior to that date would not be permitted.&amp;nbsp; The Company is currently evaluating the impact of the adoption of this ASU to the Company&amp;#x2019;s consolidated financial statements and related disclosures.&lt;/div&gt;&lt;/div&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

Credit risk is minimal with public owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing work on such projects. While most public contracts are subject to termination at the election of the government entity, in the event of termination the Company is entitled to receive the contract price for completed work and reimbursement of termination-related costs. Credit risk with private owners is minimized because of statutory mechanic&amp;#x2019;s liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Revenues are recognized on the percentage-of-completion method, measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs related to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. 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.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Changes in estimated revenues and gross margin resulted in a net charge of $1.1 million and $12.3 million during the three months and nine months ended September 30, 2015, respectively, included in Operating income (loss), or $(0.06) and $(0.64) per diluted share attributable to Sterling common stockholders, respectively, included in Net income (loss) attributable to Sterling common stockholders. Changes in estimated revenues and gross margin resulted in a net loss of $4.5 million and a net gain of $0.4 million during the three months and nine months ended September 30, 2014, respectively, included in Operating income (loss), or $(0.24) and $0.02 per diluted share attributable to Sterling common stockholders, respectively, included in Net income (loss) attributable to Sterling common stockholders.&lt;/div&gt;&lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt"&gt;Our contracts generally take 12 to 36 months to complete.

Refer to Note 16 of the Notes to Consolidated Financial Statements included in the 2014 Form 10-K for further information. The Company recorded stock-based compensation expense of $0.8 million and $1.3 million for the three and nine months ended September 30, 2015, respectively, and $0.2 million and $0.6 million for the three and nine months ended September 30, 2014, respectively.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;At September 30, 2015, total unrecognized compensation cost related to unvested common stock awards was $3.0 million. This cost is expected to be recognized over a weighted average period of 2.0 years. There was no unrecognized compensation expense related to stock options at September 30, 2015 and 2014. There were no proceeds received by the Company from the exercise of stock options for the three and nine months ended September 30, 2015 and such proceeds were immaterial for the three and nine months ended September 30, 2014. No stock options were granted in the three or nine months ended September 30, 2015 or 2014. At September 30, 2015, there were 0.8 million shares of common stock covered by outstanding unvested common stock.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;On January 1, 2015, the Company launched a long- and short-term incentive program for certain employees. The short-term incentive plan is paid in cash if certain short-term achievements are met and the long-term incentive plan is paid with the Company&amp;#x2019;s stock if certain long-term achievements are met. The stock based awards are awarded based in two parts; 50% is based on completing a service period of three years and 50% is based on the level of achievement of the Company&amp;#x2019;s total shareholder return (&amp;#x201c;TSR&amp;#x201d;) compared to the TSR of a designated peer group over a three year period. The service based awards are recorded as usual; however, the awards based on TSR must be valued using a Monte Carlo simulation. Based on the valuation obtained using Monte Carlo simulation and valuation on the service based awards, the Company recorded an expense of $0.1 million and $0.3 million, which was included in the $0.8 million and $1.3 million expense mentioned above, for the three and nine months ended September 30, 2015, respectively.&lt;/div&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;On March 9, 2015, the Company entered into a three-year employment agreement with Paul J. Varello, the Company&amp;#x2019;s Chief Executive Officer (&amp;#x201c;CEO&amp;#x201d;). As part of the agreement, Mr. Varello will be paid an annual salary of $1 and received 600,000 shares of the Company&amp;#x2019;s common stock which vest in three equal installments on the first three anniversaries of the March 9, 2015 award date. The award is a special one-time plan for the CEO and was approved by the Company&amp;#x2019;s stockholders at its 2015 Annual Meeting in May 2015 and was valued at approximately $2.5 million.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 16 --&gt;    &lt;div style="page-break-before: always; margin-top: 6pt"&gt;   &amp;nbsp;  &lt;/div&gt;  &lt;!-- Field: /Page --&gt;  &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0"&gt;On July 3, 2015&lt;div style="display: inline; font-weight: bold;"&gt;, &lt;/div&gt;the Company granted our former CFO a discretionary bonus consisting of 106,478 shares of the Company's common stock valued at $0.4 million which was included in the $0.8 million and $1.3 million expense mentioned above for the three and nine months ended September 30, 2015.&lt;/div&gt;&lt;/div&gt;</us-gaap:StockholdersEquityNoteDisclosureTextBlock>

Certain of the Company&amp;#x2019;s accounting policies require higher degrees of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts under the percentage-of-completion method, the valuation of long-term assets (including goodwill), and income taxes. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:UseOfEstimates>

The December 31, 2014 condensed consolidated balance sheet data herein was derived from audited financial statements, but as discussed above, does not include all disclosures required by GAAP.

For investments in subsidiaries and construction joint ventures that are not wholly-owned, but where the Company exercises control, the equity held by the remaining owners and their portions of net income (loss) are reflected in the balance sheet line item &#x201c;Noncontrolling interests&#x201d; in &#x201c;Equity&#x201d; and the statement of operations line item &#x201c;Noncontrolling owners&#x2019; interests in earnings of subsidiaries,&#x201d; respectively. All significant intercompany accounts and transactions have been eliminated in consolidation. For all years presented, the Company had no subsidiaries where its ownership interests were less than 50%.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Where the Company is a noncontrolling joint venture partner, and otherwise not required to consolidate the joint venture entity, its share of the operations of such construction joint venture is accounted for on a pro rata basis in the condensed consolidated statements of operations and as a single line item (&#x201c;Receivables from and equity in construction joint ventures&#x201d;) in the condensed consolidated balance sheets. This method is an acceptable modification of the equity method of accounting which is a common practice in the construction industry. Refer to Note 3<div style="display: inline; color: red"> </div>for further information regarding the Company&#x2019;s construction joint ventures.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Under U.S. GAAP, the Company must determine whether each entity, including joint ventures in which it participates, is a variable interest entity (&#x201c;VIE&#x201d;). This determination focuses on identifying which owner or joint venture partner, if any, has the power to direct the activities of the entity and the obligation to absorb losses of the entity or the right to receive benefits from the entity disproportionate to its interest in the entity, which could have the effect of requiring us to consolidate the entity in which we have a noncontrolling variable interest. Refer to Note 10 for further information regarding the Company&#x2019;s consolidated VIE.</div>    <!-- Field: Page; Sequence: 8 -->    <div style="page-break-before: always; margin-top: 6pt">   &nbsp;  </div>  <!-- Field: /Page -->  <div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><div style="display: inline; font-style: italic;">Use of Estimates</div></div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The preparation of the accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions 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 of the Company&#x2019;s accounting policies require higher degrees of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts under the percentage-of-completion method, the valuation of long-term assets (including goodwill), and income taxes. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><div style="display: inline; font-style: italic;">Reclassification</div></div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 2pt 0.05in 2pt 0">A reclassification has been made to historical financial data on our condensed consolidated statement of cash flows to conform to our current year presentation.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><div style="display: inline; font-style: italic;">Revenue Recognition</div></div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">The Company is a general contractor which engages in various types of heavy civil construction projects principally for public (government) owners. Credit risk is minimal with public owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing work on such projects. While most public contracts are subject to termination at the election of the government entity, in the event of termination the Company is entitled to receive the contract price for completed work and reimbursement of termination-related costs. Credit risk with private owners is minimized because of statutory mechanic&#x2019;s liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Revenues are recognized on the percentage-of-completion method, measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs related to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. 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.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Changes in estimated revenues and gross margin resulted in a net charge of $1.1 million and $12.3 million during the three months and nine months ended September 30, 2015, respectively, included in Operating income (loss), or $(0.06) and $(0.64) per diluted share attributable to Sterling common stockholders, respectively, included in Net income (loss) attributable to Sterling common stockholders. Changes in estimated revenues and gross margin resulted in a net loss of $4.5 million and a net gain of $0.4 million during the three months and nine months ended September 30, 2014, respectively, included in Operating income (loss), or $(0.24) and $0.02 per diluted share attributable to Sterling common stockholders, respectively, included in Net income (loss) attributable to Sterling common stockholders.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our contracts generally take 12 to 36 months to complete. The Company generally provides a one to two-year warranty for workmanship under its contracts when completed. Warranty claims historically have been insignificant.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><div style="display: inline; font-style: italic;">Financial Instruments and Fair Value</div></div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The fair value of financial instruments is the amount at which the instrument could be exchanged in a current transaction between willing parties. The Company&#x2019;s financial instruments are cash and cash equivalents, restricted cash used as collateral for a letter of credit and restricted cash maintained in an escrow account, short-term and long-term contracts receivable, derivatives, accounts payable, mortgage and notes payable, a revolving loan (the &#x201c;Revolving Loan&#x201d;) with Nations Fund I, LLC and Nations Equipment Finance, LLC, as administrative agent and collateral agent for the lender (&#x201c;Nations&#x201d;), a term loan (the &#x201c;Term Loan&#x201d;) with Nations, and an earn-out liability related to the acquisition of J. Banicki Construction, Inc. (&#x201c;JBC&#x201d;).</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The recorded values of cash and cash equivalents, and restricted cash, short-term contracts receivable and accounts payable approximate their fair values based on their liquidity and/or short-term nature. The recorded value of long-term contracts receivable was based on the amount of future cash flows discounted using the creditor&#x2019;s borrowing rate and such recorded value approximated fair value.</div>    <!-- Field: Page; Sequence: 9 -->    <div style="page-break-before: always; margin-top: 6pt">   &nbsp;  </div>  <!-- Field: /Page -->  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 0 0">The Company provides credit in the normal course of business, principally to public (government) owners, and performs ongoing credit evaluations, as deemed necessary, but generally does not require collateral to support such receivables.&nbsp; In an effort to reduce its credit exposure, as well as accelerate its cash flows, in August 2015, the Company completed the sale, on a non-recourse basis, of its only long-term contract receivable pursuant to a factoring agreement with a related party. The Company received approximately $7.1&nbsp;million upon the closing of this transaction and recorded a loss of approximately $1.4 million in &#x201c;Other operating (expense) income, net.&#x201d;&nbsp; As such, we did not have a long-term contract receivable at September 30, 2015. The long-term contract receivable was historically discounted at 4.25% and recorded at fair value. Interest earned related to the long-term contract receivable was less than $0.1 million and $0.2 million for the three and nine months ended September 30, 2015, respectively, and $0.1 million and $0.3 million for the three and nine months ended September 30, 2014, respectively.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">Refer to Note 5 regarding the fair value of derivatives, Note 8 regarding the fair value of an earn-out liability along with the most current amendments, and Note 12 regarding the fair value of the Revolving Loan and the Term Loan. The Company had one mortgage outstanding at December 31, 2014 with a remaining balance of $0.1 million and was fully paid in June 2015. At December 31, 2014, the fair value of the mortgage approximated book value. The Company also has long-term notes payable of $2.5 million related to machinery and equipment purchased which have payment terms ranging from 3 to 5 years and associated interest rates ranging from 3.12% to 6.29%. The fair value of the notes payable approximates their book value. The Company does not have any off-balance sheet financial instruments other than operating leases (refer to Note 14 of the Notes to Consolidated Financial Statements in the 2014 Form 10-K).</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0; background-color: white">In order to assess the fair value of the Company&#x2019;s financial instruments, the Company uses the fair value hierarchy established by GAAP which prioritizes the inputs used in valuation techniques into the following three levels:</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in">Level 1 Inputs &#x2013; Based upon quoted prices for identical assets in active markets that the Company has the ability to access at the measurement date.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in">Level 2 Inputs &#x2013; Based upon quoted prices (other than Level 1) in active markets for similar assets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset such as interest rates, yield curves, volatilities and default rates and inputs that are derived principally from or corroborated by observable market data.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0.25in">Level 3 Inputs &#x2013; Based on unobservable inputs reflecting the Company&#x2019;s own assumptions about the assumptions that market participants would use in pricing the asset based on the best information available.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">For each financial instrument, the Company uses the highest priority level input that is available in order to appropriately value that particular instrument. In certain instances, Level 1 inputs are not available and the Company must use Level 2 or Level 3 inputs. In these cases, the Company provides a description of the valuation techniques used and the inputs used in the fair value measurement.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><div style="display: inline; font-style: italic;">Out-of-Period Adjustment</div></div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 0">During the first quarter of 2015, the Company recorded a $2.8 million out-of-period decrease in revenue that affected our results of operations for the nine months ended September 30, 2015. The adjustment was identified during our first quarter review of projects. Management evaluated the effect of the adjustment on the Company&#x2019;s financial statements based on SEC Staff Accounting Bulletin (&#x201c;SAB&#x201d;) No. 99 and SAB 108 and concluded that it was immaterial to the current and prior year&#x2019;s consolidated financial statements.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 6pt 0.05in 6pt 0"><div style="display: inline; font-style: italic;">Recent Accounting Pronouncements</div></div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In August 2015, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) 2015-15, &#x201c;Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements.&#x201d; The guidance, which incorporates the SEC Staff Announcement at the June 18, 2015 EITF meeting and is effective upon announcement, provides clarification related to the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. The guidance states that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company is currently accounting for its debt issuance costs for its Term Loan and line-of-credit Revolver Loan in this manner and would only expect a change in presentation of the deferred amounts related to the Term Loan upon adoption as required by ASU 2015-03.

Early adoption is permitted as of the beginning of an interim or annual reporting period. Although early adoption is permitted, the Company expects to adopt this guidance as required and does not expect a material impact to the Company&#x2019;s consolidated financial statements.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In April 2015, the FASB issued ASU 2015-03, &#x201c;Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.&#x201d; The guidance, which is effective for annual reporting periods beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2015, requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The adoption of this ASU requires retrospective application to all periods presented. Although early adoption is permitted, the Company expects to adopt this guidance as required and expects a change in the presentation of our consolidated balance sheets and related disclosures.

Early adoption is permitted. Although early adoption is permitted, the Company expects to adopt this guidance as required and does not expect a material impact to the Company&#x2019;s consolidated financial statements.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">In May 2014, the FASB issued ASU 2014-09, &#x201c;Revenue from Contracts with Customers.&#x201d; The guidance defines the steps to recognize revenue for entities that have contracts with customers. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 by one year. As a result, the amendments in ASU 2014-09 are effective for public companies for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Entities would be permitted to adopt this ASU as early as the original public entity effective date, which was annual reporting periods beginning after December 15, 2016 and interim periods therein. Early adoption prior to that date would not be permitted.&nbsp; The Company is currently evaluating the impact of the adoption of this ASU to the Company&#x2019;s consolidated financial statements and related disclosures.</div></div><span></span>

<td class="text">This Amendment No. 1 on Form 10-Q/A amends the Company's Quarterly Report on Form 10-Q for the period ended September 30, 2015, which was filed with the Securities and Exchange Commission on November 9, 2015 (&#x201c;the Original Filing&#x201d;). The Company is filing this Amendment solely for the purpose of correcting typographical errors in Item 1. Financial Statements, in Note 10 to the condensed consolidated financial statements. The corrections eliminated the parenthesis around $1,108 and $2,941 for the three and nine months ended September 30, 2015, respectively, in the caption &#x201c;Net (loss) income attributable to Sterling common stockholders,&#x201d; and also removed the word "(loss)" in the caption. This Amendment is presented as of the filing date of the Original Filing. Other than as set forth above, this Amendment does not modify or update disclosures in the Original Filing and does not reflect events that may have occurred after that date.<span></span>

The amount of the Revolving Loan that may be borrowed from time to time is determined quarterly and may not exceed $20.0 million. In addition, the sum of the outstanding balances of the Equipment-based Facility may not exceed the lesser of $40.0 million or 65% of the appraised value of the collateral pledged for the loans. At September 30, 2015, the Company had approximately $34.3 million of borrowing base which was the result of calculating 65% of the appraised value (where appraised value equals net operating liquidated value) of the Company&#x2019;s collateral. The Revolving Loan may be utilized by the Company to provide ongoing working capital and for other general corporate purposes. At September 30, 2015, the Company had $13.1 million drawn on the Revolving Loan, $19.0 million Term Loan outstanding and $2.2 million of borrowings available.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The Equipment-based Facility bears interest at an initial fixed annual rate of 12%, which is subject to (i) a decrease of up to two percentage points based on the Company's fixed charge coverage ratio for each of the most recently ended four quarters beginning with the four quarters ended June 30, 2016; and (ii) an increase of two percentage points beginning December 31, 2015 based on the fixed charge coverage ratio at the end of the following two quarters. Principal on the Term Loan is payable in 47 monthly installments (with accrued interest) with a final payment of the then outstanding principal amount on May 29, 2019. Up to $5.0 million of the Term Loan may be prepaid in any year, but subject to a pre-payment fee that declines as the Term Loan nears maturity. Outstanding Revolving Loans are payable in full thirty days before the maturity date of the Term Loan.</div>    <!-- Field: Page; Sequence: 18 -->    <div style="page-break-before: always; margin-top: 6pt">   &nbsp;  </div>  <!-- Field: /Page -->  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The Equipment-based Facility is secured by all of the Company's personal property except accounts receivable, including all of its construction equipment, which forms the basis of availability under the Revolving Loan. The Equipment-based Facility is also secured by one-half of the equipment of the Company's 50%-owned affiliates, Road and Highway Builders, LLC and Myers &amp; Sons Construction, L.P. pursuant to a separate security agreement with those entities. If a default occurs, Nations may exercise the Company's rights in the collateral, with all of the rights of a secured party under the Uniform Commercial Code, including, among other things, the right to sell the collateral at public or private sale.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">The proceeds of the Term Loan of $20.0 million and our initial draw of $14.6 million under the Revolving Loan were utilized by the Company to repay the balance outstanding and terminate the Prior Credit Facility and for other general corporate purposes.

On June 2, 2015, the Company purchased an insurance policy with a five-year term on Mr. Buenting that provides a lump sum disability benefit in the principal sum of $20 million. &nbsp;In the event of Mr. Buenting&#x2019;s permanent total disability, the principal sum becomes payable to the Company, and in turn the Company is obligated to use the proceeds of the policy to purchase Mr. Buenting&#x2019;s 50% member&#x2019;s interest in RHB in accordance with the terms of the amended agreements. No other transfer of member&#x2019;s interest is permitted other than to the selling representative in the event of Mr. Buenting&#x2019;s death or permanent disability. In the event that Mr. Buenting resigns his 50% interest in RHB or is terminated without cause (i.e., termination other than through cause, permanent disability or death), RHB shall be dissolved unless both members agree otherwise. The amended agreements were entered into in order to eliminate the earnings-per-share volatility caused by the buy/sell option.</div>    <!-- Field: Page; Sequence: 14 -->    <div style="page-break-before: always; margin-top: 6pt">   &nbsp;  </div>  <!-- Field: /Page -->  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 0 0">The amended agreements resulted in an obligation to purchase Mr. Buenting&#x2019;s 50% member&#x2019;s interest that the Company is certain to incur, either because of Mr. Buenting&#x2019;s permanent disability or death; therefore, the Company has classified the noncontrolling interest as mandatorily redeemable and has recorded a liability in &#x201c;Member&#x2019;s interest subject to mandatory redemption and undistributed earnings&#x201d; on the condensed consolidated balance sheets.

Based on these agreements, the Company does not believe that it is likely that the exercise of these options would ever transpire; therefore, there has been no value placed on these options which resulted in no impact to our condensed consolidated financial statements.

Wadsworth Construction Company, LLC (&#x201c;RLW&#x201d;), RLW agreed to additional purchase price payments of up to $5 million to be paid over a five-year period. The additional purchase price is in the form of an earn-out and is classified as a Level 3 fair value measurement. In making this valuation, the unobservable input consisted of forecasted EBITDA for the periods after the period being reported on through July 31, 2016. The additional purchase price is calculated generally as 50% of the amount by which EBITDA exceeds $2.0 million for each of the calendar years 2011 through 2015 and $1.2 million for the seven months ended July 31, 2016.</div>    <!-- Field: Page; Sequence: 15 -->    <div style="page-break-before: always; margin-top: 6pt">   &nbsp;  </div>  <!-- Field: /Page -->  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">On January 23, 2014, RLW, the former owner of JBC and the Company agreed to amend the above mentioned earn-out agreement in order to reduce the Company&#x2019;s recorded liability at that time, while providing the former owner, who at the time was the chief executive officer of JBC, a greater incentive to meet earnings benchmarks. The amendment resulted in a reduction of $0.6 million in the Company&#x2019;s earn-out liability, thereby reducing the total earn-out liability to $1.4 million on December 31, 2013. As part of the amendment, a payment of $0.8 million was made during the first quarter of 2014. The amendment increased the total available earn-out from $5.0 million to $10.0 million if certain EBITDA benchmarks are met. The amendment extended the earn-out period through December 31, 2017 and reduced the benchmark EBITDA for 2014 and 2015 to $1.5 million and increased it to $2.0 million in 2016 and 2017. This earn-out liability continues to be classified as a Level 3 fair value measurement and the unobservable inputs continue to be the forecasted EBITDA for the periods after the period being reported on through December 31, 2017. There was no yearly excess forecasted EBITDA in our calculation at September 30, 2015 of the minimum EBITDA benchmarks for the years 2015 through 2017. The discounted present value of the additional purchase price was estimated to be $0.3 million as of September 30, 2014 which included a revaluation benefit of $0.3 million recorded in interest income on the condensed consolidated statement of operations. The undiscounted earn-out liability as of September 30, 2015 is estimated at zero and could increase by $9.3 million if EBITDA during the earn-out period increases $18.5 million or more and could decrease by the full amount of the liability for the year if EBITDA does not exceed the minimum threshold for that year. Each year is considered a discrete earnings period and future losses by JBC, if any, would not reduce the Company&#x2019;s liability in years in which JBC has exceeded its earnings benchmark. Any significant increase or decrease in actual EBITDA compared to the forecasted amounts would result in a significantly higher or lower fair value measurement of the additional purchase price. This liability is included in other long-term liabilities on the accompanying condensed consolidated balance sheets. As part of recording the present value of this liability, the Company incurs accreted interest expense for the passage of time until the time of settlement. The Company incurred accreted interest expense of zero and $0.3 million for the three months and nine months ended September 30, 2014, respectively. As part of the updated EBITDA forecast, the Company reduced its liability to zero and recorded interest income of $0.3 million in the first quarter of 2015. There has been no change in the value of this liability; therefore, the interest income was zero and $0.3 million for the three and nine months ended September 30, 2015, respectively.</div></div><span></span>

There were no proceeds received by the Company from the exercise of stock options for the three and nine months ended September 30, 2015 and such proceeds were immaterial for the three and nine months ended September 30, 2014.

The stock based awards are awarded based in two parts; 50% is based on completing a service period of three years and 50% is based on the level of achievement of the Company&#x2019;s total shareholder return (&#x201c;TSR&#x201d;) compared to the TSR of a designated peer group over a three year period. The service based awards are recorded as usual; however, the awards based on TSR must be valued using a Monte Carlo simulation. Based on the valuation obtained using Monte Carlo simulation and valuation on the service based awards, the Company recorded an expense of $0.1 million and $0.3 million, which was included in the $0.8 million and $1.3 million expense mentioned above, for the three and nine months ended September 30, 2015, respectively.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0.05in 2pt 0">On March 9, 2015, the Company entered into a three-year employment agreement with Paul J.

On January 27, 2015, the Company announced its preliminary fourth quarter and full year 2014 results and that the Company was not in compliance with the Prior Credit Facility&#x2019;s tangible net worth covenant. On March 16, 2015, the Company announced actual fourth quarter and full year 2014 results and that a waiver of the covenant breach had been obtained. As a result of these announcements, the Company&#x2019;s stock price fluctuated greatly during the first quarter of 2015, dropping from a January 2<div style="display: inline; bottom:.33em; font-size: 82%; position: relative; vertical-align: baseline;">nd</div> price of $6.41 to a March 31<div style="display: inline; bottom:.33em; font-size: 82%; position: relative; vertical-align: baseline;">st</div> price of $4.52.</div>    <!-- Field: Page; Sequence: 19 -->    <div style="page-break-before: always; margin-top: 6pt">   &nbsp;  </div>  <!-- Field: /Page -->  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Due to the decrease in the stock price that resulted and our first quarter loss, the Company noted that a goodwill impairment triggering event occurred during the first quarter of 2015. Therefore, we updated our fourth quarter goodwill impairment assessment using the two methods discussed in Note 8 of the Notes to Consolidated Financial Statements in the 2014 Form 10-K. The assessment used updated first quarter information which incorporated the Company&#x2019;s stock price at March 31, 2015 and reduced gross margins used in our discounted cash flow model projections. Based on this revised testing, there was no goodwill impairment and we determined that the fair value of the Company&#x2019;s equity was approximately 8% above the carrying value of the Company&#x2019;s equity.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">During the third quarter of 2015, the Company noted that the revenue projections used in our first quarter goodwill impairment assessment were higher than our actual results for the second and third quarters of 2015; therefore, the Company determined that a goodwill impairment triggering event occurred during the third quarter of 2015. As such, we updated our first quarter goodwill impairment assessment with third quarter 2015 information which incorporated the Company&#x2019;s stock price at September 30, 2015 and reduced the projected revenue used in our discounted cash flow model. The forecasted cash flows took into consideration historical and recent results, backlog and near term projects, recent developments, strategic actions and management&#x2019;s outlook for the future. The forecast and growth assumptions included, among other things, improved project performance, continuation of a strong base market, and margin improvements driven by incremental margin product opportunities and pursuing work in adjacent markets. Based on this revised testing, there was no goodwill impairment and we passed by an improved margin compared to that of our first quarter&#x2019;s 2015 assessment margin.</div>  <div style=" font-size: 10pt; text-align: justify; text-indent: 0.25in; margin: 5pt 0 2pt">Our third quarter goodwill impairment assessment&#x2019;s concluded fair value could be negatively impacted if actual future performance falls short of the collective cash flow model assumptions or if our stock price is adversely affected. If based on future assessments, our goodwill is deemed to be impaired; the impairment would result in a charge to earnings which could be material.</div></div><span></span>
