1. BUSINESS

Description of the Business

Integrated Electrical Services, Inc. is a holding company that owns and manages operating subsidiaries in business activities across a variety of end markets. Our operations are currently organized into four principal business segments, based upon the nature of our current products and services:

The words “IES”, the “Company”, “we”, “our”, and “us” refer to Integrated Electrical Services, Inc. and, except as otherwise specified herein, to our wholly-owned subsidiaries.

Our Communications segment is a leading provider of network infrastructure products and services. Services offered include the design, installation and maintenance of network infrastructure for numerous industry groups. We provide design and installation of audio/visual, telephone, fire, wireless and intrusion alarm systems as well as design/build, service and maintenance of data network systems. We perform services across the United States from our ten offices, headquartered in Tempe, Arizona.

Our Residential segment provides electrical installation services for single-family housing and multi-family apartment complexes and CATV cabling installations for residential and light commercial applications. In addition to our core electrical construction work, the Residential segment provides services for the installation of residential solar power, smart meters, electric car charging stations and stand-by generators, both for new construction and existing residences. The segment is comprised of 24 locations, with headquarters in Houston, Texas. Residential locations geographically cover Texas, the Sun-Belt, and the Western and Mid-Atlantic regions of the United States, including Hawaii.

Our Commercial & Industrial segment offers a broad range of electrical design, construction, renovation, engineering and maintenance services to the commercial and industrial markets. The Commercial & Industrial segment consists of 18 locations, headquartered in Houston, Texas. Locations geographically cover Texas, Nebraska, Colorado, Oregon and the Mid-Atlantic region. Services include the design of electrical systems within a building or complex, procurement and installation of wiring and connection to power sources, end-use equipment and fixtures, as well as contract maintenance. We focus on projects that require special expertise, such as design-and-build projects that utilize the capabilities of our in-house experts, or projects which require specific market expertise, such as transmission and distribution and power generation facilities. We also provide service, maintenance and renovation and upgrade work, which tends to be either recurring or have lower sensitivity to economic cycles, or both. We provide services for a variety of projects, including: high-rise residential and office buildings, power plants, manufacturing facilities, data centers, chemical plants, refineries, wind farms, solar facilities, municipal infrastructure and health care facilities, and residential developments. Our utility services consist of overhead and underground installation and maintenance of electrical and other utilities transmission and distribution networks, installation and splicing of high-voltage transmission and distribution lines, substation construction and substation and right-of-way maintenance. Our maintenance services generally provide recurring revenues that are typically less affected by levels of construction activity.

Our Infrastructure Solutions segment provides maintenance and repair services to several industries, including electric motor repair and rebuilding for the steel, railroad, marine, petrochemical, pulp and paper, wind energy, mining, automotive and power generation industries. Infrastructure Solutions repairs and manufactures industrial lifting magnets for the steel and scrap industries, provides locomotive maintenance, remanufacturing, and repair services to the rail industry, and manufactures and rebuilds power assemblies, engine parts, and other components for large diesel engines. Infrastructure Solutions is made up of nine total locations, which includes our Infrastructure Solutions headquarters in Ohio. These segment locations geographically cover Alabama, Indiana, Ohio, West Virginia, Maryland and California.

Related Party Transactions

On December 12, 2007, we entered into the Tontine Term Loan, with Tontine, which the Company terminated and prepaid in full in the second quarter of fiscal 2013. See Note 4, “Debt – The Tontine Term Loan,” for further discussion.

On March 29, 2012, we entered into a sublease agreement with Tontine Associates, LLC, an affiliate of Tontine Capital Partners, L.P. (together with its affiliates “Tontine”), for corporate office space in Greenwich, Connecticut. The lease extends from April 1, 2012 through March 31, 2014, with monthly payments due in the amount of $6. The lease has terms at market rates and payments by the Company are at a rate consistent with that paid by Tontine Associates, LLC to its landlord. See also Note 2, “Controlling Shareholder,” for further discussion.

Basis of Financial Statement Preparation

The accompanying unaudited condensed consolidated financial statements include the accounts of IES and its wholly-owned subsidiaries, and have been prepared in accordance with the instructions to interim financial reporting as prescribed by the SEC. These interim financial statements do not include all disclosures required by accounting principles generally accepted in the United States of America, and should be read in the context of the consolidated financial statements and notes thereto filed with the Securities and Exchange Commission (the “SEC”) in our Annual Report on Form 10-K for the year ended September 30, 2013. In the opinion of management, the unaudited condensed consolidated financial statements contained in this report include all known accruals and adjustments necessary for a fair statement of the results of operations for the periods reported herein. All such adjustments are of a normal recurring nature.

Fair Value of Financial Instruments

Our financial instruments consist of cash and cash equivalents, accounts receivable, notes receivable, investments, accounts payable, a loan agreement, and an interest rate swap agreement. We believe that the carrying value of financial instruments, with the exception of our cost method investment in EnerTech, in the accompanying Consolidated Balance Sheets, approximates their fair value due to their short-term nature.

We estimate the fair value of our investment in EnerTech Capital Partners II L.P. (“EnerTech”) (Level 3) using quoted market prices for underlying publicly traded securities, and estimated enterprise values determined using cash flow projections and market multiples of the underlying non-public companies. For additional information on our investment in EnerTech, please refer to Note 9, “Securities and Equity Investments”.

For a detailed discussion of financial assets and liabilities measured at fair value on a recurring basis, please refer to Note 11, “Fair Value Measurements” in the Notes to these Consolidated Financial Statements.

Goodwill

Goodwill attributable to each reporting unit is tested for impairment by comparing the fair value of each reporting unit with its carrying value. Fair value is determined using discounted cash flows. These impairment tests are required to be performed at least annually. Significant estimates used in the methodologies include estimates of future cash flows, future short-term and long-term growth rates, and weighted average cost of capital for each of the reportable units. On an ongoing basis (absent any impairment indicators), we perform an impairment test annually using a measurement date of September 30.

Intangible Assets

Intangible assets with definite lives are amortized over their estimated useful lives based on expected economic benefit with no residual value. Customer relationships are amortized assuming gradual attrition. Intangible assets with indefinite lives are not subject to amortization. We perform a test for impairment annually, or more frequently when indicators of impairment are present.

(All Amounts in Thousands Except Share Amounts)

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities, disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates are primarily used in our revenue recognition of construction in progress, fair value assumptions in analyzing goodwill, investments, intangible assets and long-lived asset impairments and adjustments, allowance for doubtful accounts receivable, stock-based compensation, reserves for legal matters, assumptions regarding estimated costs to exit certain segments, realizability of deferred tax assets, unrecognized tax benefits and self-insured claims liabilities and related reserves.

Inventories

Inventories generally consist of raw materials, work in process, finished goods, and parts and supplies held for use in the ordinary course of business. Inventory is valued at the lower of cost or market generally using the historical average cost or first-in, first-out (FIFO) method. When circumstances dictate, we write down inventory to its estimated realizable value based on assumptions about future demand, market conditions, plans for disposal, and physical condition of the product. Where shipping and handling costs to receive materials are borne by us, these charges are included in inventory and charged to cost of services upon use in our projects or the providing of services.

Cash and Cash Equivalents

We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Comprehensive Income

Comprehensive income includes all changes in equity during a period except those resulting from investments by and distributions to stockholders.

Seasonality and Quarterly Fluctuations

Results of operations from our Residential construction segment are seasonal, depending on weather trends, with typically higher revenues generated during spring and summer and lower revenues during fall and winter. The Communications, Commercial & Industrial, and Infrastructure Solutions segments of our business are less subject to seasonal trends, as work in these segments generally is performed inside structures protected from the weather. Our service and maintenance business is generally not affected by seasonality. In addition, the construction industry has historically been highly cyclical. Our volume of business may be adversely affected by declines in construction projects resulting from adverse regional or national economic conditions. Quarterly results may also be materially affected by the timing of new construction projects. Results for our Infrastructure Solutions segment may be affected by the timing of scheduled outages at our customers’ facilities. Accordingly, operating results for any fiscal period are not necessarily indicative of results that may be achieved for any subsequent fiscal period.

New Accounting Pronouncements

In February 2013, the FASB issued accounting guidance related to the reporting of amounts reclassified out of accumulated other comprehensive income. This guidance sets forth new disclosure requirements for items reclassified from accumulated other comprehensive income by requiring disclosures for both the changes in accumulated other comprehensive income by component and where the significant items reclassified from accumulated other comprehensive income are classified in the Statements of Consolidated Comprehensive Income. See Note 7, “Other Comprehensive Income”, for further discussion.

2. CONTROLLING SHAREHOLDER

At December 31, 2013, Tontine Capital Partners, L.P. together with its affiliates (collectively “Tontine”) was the controlling shareholder of the Company’s common stock. Accordingly, Tontine has the ability to exercise significant control over our affairs, including the election of directors and any action requiring the approval of shareholders.

While Tontine is subject to restrictions under federal securities laws on sales of its shares as an affiliate, pursuant to a Registration Rights Agreement between Tontine and the Company, Tontine delivered a request to the Company for registration of all of its shares of IES common stock, and on February 21, 2013, the Company filed a shelf registration statement to register Tontine’s shares (as amended, the “Shelf Registration Statement”). The Shelf Registration Statement was declared effective by the SEC on June 18, 2013. As long as the Shelf Registration Statement remains effective, Tontine has the ability to resell any or all of its shares from time to time in one or more offerings, as described in the Shelf Registration Statement and in any prospectus supplement filed in connection with an offering pursuant to the Shelf Registration Statement.

Should Tontine sell or otherwise dispose of all or a portion of its position in IES, a change in ownership could occur. A change in ownership, as defined by Internal Revenue Code Section 382, could reduce the availability of net operating losses (“NOLs”) for federal and state income tax purposes. On January 28, 2013, the Company implemented a tax benefit protection plan (the “NOL Rights Plan”) that is designed to deter an acquisition of the Company’s stock in excess of a threshold amount that could trigger a change of control within the meaning of Internal Revenue Code Section 382. For additional information on the NOL Rights Plan, please see our Current Report on Form 8-K, filed with the SEC on January 28, 2013. There can be no assurance that the NOL Rights Plan will be effective in deterring a change of control or protecting the NOLs. Furthermore, a change in control would trigger the change of control provisions in a number of our material agreements, including our credit facility, bonding agreements with our sureties and certain employment contracts with certain officers and employees of the Company.

3. STRATEGIC ACTIONS

The 2011 Restructuring Plan

In the second quarter of our 2011 fiscal year, we began a restructuring program (the “2011 Restructuring Plan”) that was designed to consolidate operations within our Commercial & Industrial business. Pursuant to the 2011 Restructuring Plan, we began the closure of certain underperforming facilities within our Commercial & Industrial operations. The 2011 Restructuring Plan was a key element of our commitment to return the Company to profitability.

The facilities directly affected by the 2011 Restructuring Plan were in several locations throughout the country, including Arizona, Florida, Iowa, Massachusetts, Louisiana, Nevada and Texas. These facilities were selected due to business prospects at that time and the extended time frame needed to return the facilities to a profitable position. Closure costs associated with the 2011 Restructuring Plan included equipment and facility lease termination expenses, incremental management consulting expenses and severance costs for employees. The Company has completed the wind down of these facilities with minimal completion remaining. As part of our restructuring charges reported within discontinued operations for our Commercial & Industrial segment we recognized zero and $(4) in severance charges; zero and $47 in consulting services; and zero in costs related to lease terminations for the three months ended December 31, 2013 and 2012, respectively. Charges related to the 2011 Restructuring Plan in our fiscal year ended 2014 are expected to be immaterial.

The 2011 Restructuring Plan pertains only to our Commercial & Industrial segment. The following table summarizes the activities related to our restructuring activities by component:

4. DEBT

Debt consists of the following:

Future payments on debt as of December 31, 2013 are as follows:

For the three months ended December 31, 2013 and 2012, we incurred interest expense of $518 and $607, respectively.

The 2012 Revolving Credit Facility

On August 9, 2012, we entered into a Credit and Security Agreement (the “Credit Agreement”), for a $30,000 revolving credit facility (the “2012 Credit Facility”) with Wells Fargo Bank, National Association (“Wells Fargo”) with a maturity date of August 9, 2015, unless earlier terminated. We have entered into two amendments to the 2012 Credit Facility. On February 12, 2013, we entered into an amendment of our 2012 Credit Facility (the “Amendment”), to extend the term to August 9, 2016, add IES Renewable Energy, LLC as a borrower, and provide for a term loan (the “Wells Fargo Term Loan”). On September 13, 2013, we entered into an amendment of the 2012 Credit Facility (the “Second Amendment”), which amended the Wells Fargo Term Loan, removed the requirement to cash collateralize our outstanding letters of credit, and added IES Subsidiary Holdings Inc., Magnetech Industrial Services, Inc., and HK Engine Components, LLC, as borrowers.

The 2012 Credit Facility is guaranteed by our subsidiaries and secured by first priority liens on substantially all of our subsidiaries’ existing and future acquired assets, exclusive of collateral provided to our surety providers. The 2012 Credit Facility also restricts us from paying cash dividends and places limitations on our ability to repurchase our common stock.

The 2012 Credit Facility contains customary affirmative, negative and financial covenants. The 2012 Credit Facility requires that we maintain a fixed charge coverage ratio of not less than 1.0:1.0 at any time that our Liquidity (defined as the aggregate amount of unrestricted cash and cash equivalents on hand plus Excess Availability (as defined in the Credit Facility)) or Excess Availability fall

12

Notes to Consolidated Financial Statements

(All Amounts in Thousands Except Share Amounts)

below stipulated levels. The Second Amendment provided for tiered thresholds. Through December 31, 2013, our Liquidity could not fall below $15,000. Thereafter, our Liquidity must not fall below $20,000. Additionally, our Excess Availability must not fall below $5,000. As of December 31, 2013, our Liquidity was in excess of $15,000 and Excess Availability was in excess of $5,000; had we not met these thresholds at December 31, 2013, we would not have met the required 1.0:1.0 fixed charge coverage ratio test.

Borrowings under the 2012 Credit Facility may not exceed a “borrowing base” that is determined monthly by our lenders based on available collateral, primarily certain accounts receivables, inventories and personal property and equipment. Under the terms of the 2012 Credit Facility, amounts outstanding bear interest at a per annum rate equal to a Daily Three Month LIBOR (as defined in the Credit Agreement), plus an interest rate margin, which is determined quarterly, based on the following thresholds:

In addition, we are charged monthly in arrears for (1) an unused commitment fee of 0.50% per annum, (2) a collateral monitoring fee ranging from $1 to $2, based on the then-applicable interest rate margin, (3) a letter of credit fee based on the then-applicable interest rate margin and (4) certain other fees and charges as specified in the Credit Agreement.

At December 31, 2013, we had $5,811 available to us under the 2012 Credit Facility, $6,660 in outstanding letters of credit with Wells Fargo and no outstanding borrowings.

The Second Amendment to the 2012 Credit Facility increased our total Term Loan by $10,147 to $13,708 at September 30, 2013. The Wells Fargo Term Loan is payable in equal monthly installments of $292 through August 9, 2016, with the residual unpaid principal balance due on that date. The Second Amendment also extended the term and reduced the annual interest rate to 5% plus 3 Month LIBOR, through September 13, 2014. Following that time, the Wells Fargo Term Loan amounts outstanding bear interest at a per annum rate equal to a Daily Three Month LIBOR plus an interest rate margin, which is determined quarterly, based on the following thresholds:

The Tontine Term Loan

On December 12, 2007, we entered into the Tontine Term Loan, a $25,000 senior subordinated loan agreement, with Tontine, which the Company terminated and prepaid in full in the second quarter of fiscal 2013, as further described below.

The Tontine Term Loan bore interest at 11.0% per annum and was due on May 15, 2013. Interest was payable quarterly in cash or in-kind at our option. Any interest paid in-kind would bear interest at 11.0% in addition to the loan principal. The Tontine Term Loan was subordinated to the 2012 Credit Facility. The Tontine Term Loan was an unsecured obligation of the Company and its subsidiary borrowers and contained no financial covenants or restrictions on dividends or distributions to stockholders. The Tontine Term Loan was amended on August 9, 2012 in connection with the Company entering into the 2012 Credit Facility. The amendment did not materially impact the Company’s obligations under the Tontine Term Loan.

On April 30, 2010, we prepaid $15,000 of principal on the Tontine Term Loan. On May 1, 2010, Tontine assigned the Tontine Term Loan to Tontine Capital Overseas Master Fund II, L.P, also a related party. Pursuant to its terms, we were permitted to repay the Tontine Term Loan at any time prior to the maturity date at par, plus accrued interest without penalty within the restrictions of the 2012 Credit Facility. On February 13, 2013, we repaid the remaining $10,000 of principal on the Tontine Term Loan, plus accrued interest, with existing cash on hand and proceeds from the Wells Fargo Term Loan.

Capital Lease

The Company leases certain equipment under agreements, which are classified as capital leases and included in property, plant and equipment. Amortization of this equipment for the three months ended December 31, 2013 and 2012 was $22 and $ 46, respectively, and is included in depreciation expense in the accompanying statements of comprehensive income.

5. PER SHARE INFORMATION

Basic earnings per share is calculated as income (loss) available to common stockholders, divided by the weighted average number of common shares outstanding during the period. If the effect is dilutive, participating securities are included in the computation of basic earnings per share. Our participating securities do not have a contractual obligation to share in the losses in any given period. As a result, these participating securities will not be allocated any losses in the periods of net losses, but will be allocated income in the periods of net income using the two-class method.

Notes to Consolidated Financial Statements

(All Amounts in Thousands Except Share Amounts)

The following table reconciles the components of the basic and diluted earnings (loss) per share for the three months ended December 31, 2013 and 2012:

For the three months ended December 31, 2013 and 2012, 150,000 and zero stock options, respectively, were excluded from the computation of fully diluted earnings per share because the exercise prices of the options were greater than the average price of our common stock.

6. OPERATING SEGMENTS

We manage and measure performance of our business in four distinct operating segments: Communications, Residential, Commercial & Industrial, and Infrastructure Solutions. These segments are reflective of how the Company’s Chief Operating Decision Maker (“CODM”) reviews operating results for the purposes of allocating resources and assessing performance. The Company’s CODM is its Chief Executive Officer. For a description of our operating segments, please refer to Note 1, “Business – Description of the Business”

The accounting policies of the segments are the same as those described in the summary of significant accounting policies in Note 1, “Business”. We evaluate performance based on income from operations of the respective business units prior to the allocation of Corporate office expenses. Transactions between segments are eliminated in consolidation. Our Corporate office provides general and administrative as well as support services to our four operating segments. Management allocates costs between segments for selling, general and administrative expenses and depreciation expense.

7. OTHER COMPREHENSIVE INCOME

For the three months ended December 31, 2013, changes in other comprehensive income by component, net of tax, are detailed below, and represent net gains (losses) on our cash flow hedge.

Amounts reclassified from accumulated other comprehensive income, net of tax, were reported in interest expense in our consolidated statements of comprehensive income.

8. STOCKHOLDERS’ EQUITY

The 2006 Equity Incentive Plan became effective on May 12, 2006 (as amended, the “2006 Equity Incentive Plan”). The 2006 Equity Incentive Plan provides for grants of stock options as well as grants of stock, including restricted stock. We have approximately 1.0 million shares of common stock authorized for issuance under the 2006 Equity Incentive Plan.

Treasury Stock

During the three months ended December 31, 2013, we repurchased 33,568 common shares from our employees to satisfy minimum tax withholding requirements upon the vesting of restricted stock issued under the 2006 Equity Incentive Plan. We issued 7,500 shares out of treasury stock under our share-based compensation programs for restricted shares granted.

Restricted Stock

Restricted Stock Awards:

During the three months ended December 31, 2013 and 2012, we recognized $104 and $91, respectively, in compensation expense related to these restricted stock awards. At December 31, 2013, the unamortized compensation cost related to outstanding unvested restricted stock was $147. We expect to recognize $93 of this unamortized compensation expense during the remaining nine months of our 2014 fiscal year and $54 thereafter. A summary of restricted stock awards for the years ended September 30, 2013 and 2012 and the three months ended December 31, 2013 is provided in the table below:

Phantom Stock Units

Phantom stock units (“PSUs”) are primarily granted to the members of the Board of Directors as part of their overall compensation. These PSUs are paid via unrestricted stock grants to each director upon their departure from the Board of Directors. We record compensation expense for the full value of the grant on the date of grant. For the three months ended December 31, 2013 and 2012, we recognized $36 and $36 in compensation expense related to these grants.

From time to time, PSUs are granted to employees. These PSUs are paid via unrestricted stock grants to each employee upon the satisfaction of the grant terms. We record compensation expense for the PSUs granted to employees over the grant vesting period. For the three months ended December 31, 2013 and 2012, we recognized zero and $363 in compensation expense related to these grants.

Stock Options

We utilized a binomial option pricing model to measure the fair value of stock options granted. Our determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, the risk-free rate of return, and actual and projected employee stock option exercise behaviors. The expected life of stock options is not considered under the binomial option pricing model that we utilize. No options were granted in the three month period ended December 31, 2013. The assumptions used in the fair value method calculation for the years ended 2013 and 2012 are disclosed in the following table:

Stock-based compensation expense recognized during the period is based on the value of the portion of the share-based payment awards that is ultimately expected to vest during the period. Stock-based compensation expense recognized in the Consolidated Statements of Comprehensive Income is based on awards ultimately expected to vest. We estimate our forfeitures at the time of grant and revise, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

The following table summarizes activity under our stock option plans.

(All Amounts in Thousands Except Share Amounts)

The following table summarizes options outstanding and exercisable at December 31, 2013:

Our 2011 options vest over a three year period at a rate of one-third per year upon the annual anniversary date of the grant. Our 2013 options cliff vest at the end of a two year period ending at the anniversary date of the grant. All options expire ten years from the grant date if they are not exercised. Upon exercise of stock options, it is our policy to first issue shares from treasury stock, then to issue new share. Unexercised stock options expire July 2021 and May 2023.

During the three months ended December 31, 2013 and 2012, we recognized $62 and $3, respectively, in compensation expense related to our stock option awards. At December 31, 2013, the unamortized compensation cost related to outstanding unvested stock options was $317. We expect to recognize $182 of this unamortized compensation expense during the remaining nine months of our 2014 fiscal year and $135 thereafter.

The intrinsic value of stock options outstanding and exercisable was $33 and $31 at December 31, 2013 and 2012, respectively. The intrinsic value is calculated as the difference between the fair value as of the end of the period and the exercise price of the stock options.

In April 2000, we committed to invest up to $5,000 in EnerTech. As of September 30, 2009, we fulfilled our $5,000 investment under this commitment. As our investment is 2.21% of the overall ownership in EnerTech at December 31, 2013 and September 30, 2013, we account for this investment using the cost method of accounting. EnerTech’s investment portfolio from time to time results in unrealized losses reflecting a possible, other-than-temporary, impairment of our investment. The carrying value of our investment in EnerTech at December 31, 2013 and September 30, 2013 was $919.

The following table presents the reconciliation of the carrying value and unrealized gains to the fair value of the investment in EnerTech as of December 31, 2013 and September 30, 2013:

At each reporting date, the Company performs evaluations of impairment for this investment to determine if any unrealized losses are other-than-temporary. This evaluation considers a number of factors including, but not limited to, the length of time and extent to which the fair value has been less than cost, the financial condition and near term prospects of the issuer and management’s ability and intent to hold the securities until fair value recovers. The assessment of the ability and intent to hold these securities to recovery focuses on liquidity needs, asset and liability management objectives and securities portfolio objectives. Based on the results of this evaluation, we believe the unrealized gain at December 31, 2013 indicated our investment was not impaired.

On December 31, 2013, EnerTech’s general partner, with the consent of the fund’s investors, extended the fund through December 31, 2014. The fund will terminate on this date unless extended by the fund’s valuation committee. The fund may be extended for another one-year period through December 31, 2015 with the consent of the fund’s valuation committee.

10. EMPLOYEE BENEFIT PLANS

401(k) Plan

In November 1998, we established the Integrated Electrical Services, Inc. 401(k) Retirement Savings Plan (the “401(k) Plan”). All full-time IES employees are eligible to participate on the first day of the month subsequent to completing sixty days of service and attaining age twenty-one. Participants become vested in our matching contributions following three years of service. After suspending Company matching under the 401(k) Plan in February 2009, we reinstated the employee match in March of 2013. We recognized $65, and zero, respectively in matching expenses as of December 31, 2013 and 2012.

Infrastructure Solutions has two 401(k) plans. The first provides for employees covered by collective bargaining agreements and has no provision for employer contributions. The second provides for employees outside collective bargaining agreements and has a provision for employer contributions. We recognized $19 in matching expense during the three months ended December 31, 2013.

Executive Savings Plan

Under the Executive Deferred Compensation Plan adopted on July 1, 2004 (the “Executive Savings Plan”), certain employees are permitted to defer a portion (up to 75%) of their base salary and/or bonus for a Plan Year. The Compensation Committee of the Board of Directors may, in its sole discretion, credit one or more participants with an employer deferral (contribution) in such amount as the Committee may choose (“Employer Contribution”). The Employer Contribution, if any, may be a fixed dollar amount, a fixed percentage of the participant’s compensation, base salary, or bonus, or a “matching” amount with respect to all or part of the participant’s elective deferrals for such plan year, and/or any combination of the foregoing as the Committee may choose.

Post Retirement Benefit Plans

Certain individuals at one of the Company’s locations are entitled to receive fixed annual payments that reach a maximum amount, as specified in the related agreements, for a ten year period following retirement or, in some cases, the attainment of 62 years of age. We recognize the unfunded status of the plan as a non-current liability in our Consolidated Balance Sheet. Benefits vest 50% after ten years of service, which increases by 10% per annum until benefits are fully vested after 15 years of service. We had an unfunded benefit liability of $844 and $833 recorded as of December 31, 2013 and 2012, respectively.

Multiemployer Pension Plan

Infrastructure Solutions participates in a multiemployer direct benefit pension plan for employees covered under our collective bargaining agreement. We do not administer the plan. We do not significantly participate in this plan. As of December 31, 2012, this plan was funded at 84.9%.

11. FAIR VALUE MEASUREMENTS

Fair Value Measurement Accounting

Fair value is considered the price to sell an asset, or transfer a liability, between market participants on the measurement date. Fair value measurements assume that the asset or liability is (1) exchanged in an orderly manner, (2) the exchange is in the principal market for that asset or liability, and (3) the market participants are independent, knowledgeable, able and willing to transact an exchange. Fair value accounting and reporting establishes a framework for measuring fair value by creating a hierarchy for observable independent market inputs and unobservable market assumptions and expands disclosures about fair value measurements. Considerable judgment is required to interpret the market data used to develop fair value estimates. As such, the estimates presented herein are not necessarily indicative of the amounts that could be realized in a current exchange. The use of different market assumptions and/or estimation methods could have a material effect on the estimated fair value.

We estimate the fair value of our interest rate swap agreement with Wells Fargo to be $12 at December 31, 2013, using Level 2 inputs, including an estimated market valuation from Wells Fargo Bank. For additional information, please see Note 15, “Derivative Instruments.”

We estimate the fair value of the contingent consideration related to the acquisition of certain assets from the Acro Group to be $30 at December 31, 2013, using Level 3 inputs, including a discounted revenue projection. The fair value of this contingent liability will vary depending on actual revenues earned. For additional information, please see Note 16, “Business Combinations — Acquisition of Certain Assets from the Acro Group.”

We estimate the fair value of our unfavorable MISCOR leases to be $(461), using Level 2 inputs, including estimated market valuation including market rates from comparable properties. For additional information, please see Note 16, “Business Combinations — Acquisition of MISCOR.”

Financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2013, are summarized in the following table by the type of inputs applicable to the fair value measurements:

The table below presents a reconciliation of the fair value of our contingent consideration obligation, which uses significant unobservable inputs (Level 3).

Below is a description of the inputs used to value the assets summarized in the preceding table:

Level 1 — Inputs represent unadjusted quoted prices for identical assets exchanged in active markets.

Level 2 — Inputs include directly or indirectly observable inputs other than Level 1 inputs such as quoted prices for similar assets exchanged in active or inactive markets; quoted prices for identical assets exchanged in inactive markets; and other inputs that are considered in fair value determinations of the assets.

Level 3 — Inputs include unobservable inputs used in the measurement of assets. Management is required to use its own assumptions regarding unobservable inputs because there is little, if any, market activity in the assets or related observable inputs that can be corroborated at the measurement date.

12. INVENTORY

Inventories consist of the following components:

13. INTANGIBLE ASSETS

Intangible assets consist of the following:

Amortization of intangible assets was $134 for the three months ended December 31, 2013. Our future amortization expense for years ended September 30, is as follows:

14. COMMITMENTS AND CONTINGENCIES

Legal Matters

From time to time we are a party to various claims, lawsuits and other legal proceedings that arise in the ordinary course of business. We maintain various insurance coverages to minimize financial risk associated with these proceedings. None of these proceedings, separately or in the aggregate, are expected to have a material adverse effect on our financial position, results of operations or cash flows. With respect to all such proceedings, we record reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We expense routine legal costs related to these proceedings as they are incurred.

The following is a discussion of our significant legal matters:

Ward Transformer Site

One of our subsidiaries has been identified as one of more than 200 potentially responsible parties (“PRPs”) with respect to the clean-up of an electric transformer resale and reconditioning facility, known as the Ward Transformer Site, located in Raleigh, North Carolina, due to Polychlorinated Biphenyls (“PCBs”) contamination on and off the site. The subsidiary, which we acquired in January 1999, is believed to have sent transformers to the facility during the 1990s. Based on our investigation to date, there is evidence to support our defense that our subsidiary contributed no PCB contamination to the site.

In April 2009, two PRPs, Carolina Power and Light Company and Consolidation Coal Company, filed suit against us and most of the other PRPs in the U.S. District Court for the Eastern District of North Carolina (Western Division) to contribute to the cost of the clean-up. The plaintiffs were two of four PRPs that have commenced clean-up of on-site contaminated soils under an Emergency Removal Action pursuant to a settlement agreement and Administrative Order on Consent entered into between the four PRPs and the U.S. Environmental Protection Agency (“EPA”) in September 2005. We are not a party to that settlement agreement or Order on Consent.

In addition to the on-site clean-up, the EPA has selected approximately 50 PRPs to which it sent a Special Notice Letter in late 2008 to organize the clean-up of soils off site and address contamination of groundwater and other miscellaneous off-site issues. We were not a recipient of that letter. On January 8, 2013, the EPA held a meeting with those PRPs as well as others that were not recipients of the letter to discuss potential settlement of its costs associated with the site. The Company was invited to attend this meeting and asked to confirm whether it would participate in settlement discussions, which the Company confirmed. The Company intends to present to the EPA the evidence developed in litigation to support the argument that the Company did not contribute PCB contamination to the site. The Company has tendered a demand for indemnification to the former owner of the acquired corporation that may have transacted business with the facility. As of December 31, 2013, we have not recorded a reserve for this matter, as we believe the likelihood of our responsibility for damages is not probable and a potential range of exposure is not estimable.

Hamilton Wage and Hour

The Company is a defendant in three wage-and-hour suits seeking class action certification that were filed between August 29, 2012 and June 24, 2013, in the U.S. District Court for the Eastern District of Texas. Each of these cases is among several others filed by Plaintiffs’ attorney against contractors working in the Port Arthur, Texas Motiva plant on various projects over the last few years. The claims are based on alleged failure to compensate for time spent bussing to and from the plant, donning safety wear and other activities. It does not appear the Company will face significant exposure for any unpaid wages. In a separate earlier case based on the same allegations, a federal district court ruled that the time spent traveling on the busses is not compensable. On January 11, 2013, the U.S. Court of Appeals for the Fifth Circuit upheld the district court’s ruling finding no liability for wages for time spent bussing into the facility, and on October 8, 2013, the U.S. Supreme Court declined to review plaintiffs’ appeal of the Fifth Circuit dismissal of their claims for compensation for time spent bussing to the facility, effectively reducing the Company’s risk of liability on this issue in its cases. Our investigation indicates that all claims for time spent on other activities either were inapplicable to the Company’s employees or took place during times for which the Company’s employees were compensated. We have filed responsive pleadings and, following initial discovery, are positioning the cases to obtain a dismissal of all claims. As of December 31, 2013, we have not recorded a reserve for this matter, as we believe the likelihood of our responsibility for damages is not probable and a potential range of exposure is not estimable.

Risk-Management

We retain the risk for workers’ compensation, employer’s liability, automobile liability, general liability and employee group health claims, as well as pollution coverage, resulting from uninsured deductibles per accident or occurrence which are subject to annual aggregate limits. Our general liability program provides coverage for bodily injury and property damage. Losses up to the deductible amounts are accrued based upon our known claims incurred and an estimate of claims incurred but not reported. As a result, many of our claims are effectively self-insured. Many claims against our insurance are in the form of litigation. At December 31, 2013, we had $4,873 accrued for insurance liabilities. We are also subject to construction defect liabilities, primarily within our Residential segment. As of December 31, 2013, we had $432 reserved for these claims.

Some of the underwriters of our casualty insurance program require us to post letters of credit as collateral. This is common in the insurance industry. To date, we have not had a situation where an underwriter has had reasonable cause to effect payment under a letter of credit. At December 31, 2013, $6,347 of our outstanding letters of credit were utilized to collateralize our insurance program.

Surety

Many customers, particularly in connection with new construction, require us to post performance and payment bonds issued by a surety. Those bonds provide a guarantee to the customer that we will perform under the terms of our contract and that we will pay our subcontractors and vendors. If we fail to perform under the terms of our contract or to pay subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. We must reimburse the sureties for any expenses or outlays they incur on our behalf. To date, we have not been required to make any reimbursements to our sureties for bond-related costs.

As is common in the surety industry, sureties issue bonds on a project-by-project basis and can decline to issue bonds at any time. We believe that our relationships with our sureties will allow us to provide surety bonds as they are required. However, current market conditions, as well as changes in our sureties’ assessment of our operating and financial risk, could cause our sureties to decline to issue bonds for our work. If our sureties decline to issue bonds for our work, our alternatives would include posting other forms of collateral for project performance, such as letters of credit or cash, seeking bonding capacity from other sureties, or engaging in more projects that do not require surety bonds. In addition, if we are awarded a project for which a surety bond is required but we are unable to obtain a surety bond, the result can be a claim for damages by the customer for the costs of replacing us with another contractor.

As of December 31, 2013, the estimated cost to complete our bonded projects was approximately $55,195. We evaluate our bonding requirements on a regular basis, including the terms offered by our sureties. We believe the bonding capacity presently provided by our current sureties is adequate for our current operations and will be adequate for our operations for the foreseeable future. As of December 31, 2013, we had cash totaling $500 to collateralize our obligations to certain of our previous sureties (as is included in Other Non-Current Assets in our Consolidated Balance Sheet). Posting letters of credit in favor of our sureties reduces the borrowing availability under our 2012 Credit Facility.

On May 7, 2013, the Company and certain of its current and future subsidiaries and affiliates entered into a new agreement of indemnity (the “Surety Agreement”) with certain entities affiliated with Suremerica Surety Underwriting Services, LLC (“Suremerica”). Pursuant to the Surety Agreement, we have agreed to assign to Suremerica, among other things, as collateral to secure our obligations under the Surety Agreement, our rights, title and interest in, and all accounts receivable and related proceeds arising pursuant to, any contract bonded by Suremerica on our behalf. Further, under the Surety Agreement, we have also agreed that, upon written demand, we will deposit with Suremerica, as additional collateral, an amount determined by Suremerica to be sufficient to discharge any claim made against Suremerica on a bond issued on our behalf.

Other Commitments and Contingencies

Some of our customers and vendors require us to post letters of credit as a means of guaranteeing performance under our contracts and ensuring payment by us to subcontractors and vendors. If our customer has reasonable cause to effect payment under a letter of credit, we would be required to reimburse our creditor for the letter of credit. At December 31, 2013, $313 of our outstanding letters of credit were to collateralize our vendors.

On January 9, 2012, we entered into a settlement agreement with regard to $2,000 of collateral held by a surety who previously issued construction payment and performance bonds for us. The agreement called for a total settlement of $2,200 to be paid in monthly installments through February 2013, and based on subsequent payment defaults, was amended to provide for additional collateral and a total settlement amount of $2,025 ($2,200 less the $175 already received) to be paid in monthly installments beginning September 30, 2012 through July 2014 with an interest rate of 12%. Following a subsequent amendment to postpone or modify payment dates, on January 2, 2013, the Company tendered a notice of default to the surety and its coal mining operations, which had been pledged as additional collateral. Given the surety’s failure to make the payments due on December 31, 2012, and January 31, 2013, and its continued attempts to restructure the underlying settlement agreement, the Company concluded the collection of the receivable was not probable as of December 31, 2012, and recorded a reserve in the amount $1,725 for the first quarter of fiscal 2013, bringing the receivable’s net carrying value to zero. The charge was recorded as other expense within our Consolidated Statements of Comprehensive Income and the reserve was recorded within our current assets within the Consolidated Balance Sheet.

On March 8, 2013, the Company issued a notice of acceleration of the promissory notes signed by the two mining companies, and subsequently filed suit to enforce the acceleration and to domesticate the agreed judgment against the surety and its owner in Virginia. Following these actions, the surety entered into an amended agreement with the Company which provided for payment of $300, which was received on June 24, 2013, and additional monthly installments with final payment due June 30, 2014. As of the filing of this report on Form 10-Q, the Company had received installment payments totaling $550. The defendants have defaulted on payments due in November 2013, December 2013 and January 2014. The defendants have indicated that they are pursuing financing and expect to become current on all payments due in the near term. In the meantime, the Company expects to reinstate legal actions targeted at recovering the full amount due. The extent of recovery of the remaining balance, if any, cannot be determined. However, the possibility of a partial or full recovery exists, particularly if the defendants are successful in obtaining financing. We have classified the $550 received as of December 31, 2013 as other income within our Consolidated Statements of Comprehensive Income. Any subsequent recovery will be included in other income.

From time to time, we may enter into firm purchase commitments for materials such as copper or aluminum wire which we expect to use in the ordinary course of business. These commitments are typically for terms less than one year and require us to buy minimum quantities of materials at specific intervals at a fixed price over the term. As of December 31, 2013, we had no such open purchase commitments.

15. DERIVATIVE INSTRUMENTS

On March 1, 2013, we entered into an interest rate swap agreement with Wells Fargo Bank, N.A. in conjunction with our Wells Fargo Term Loan to hedge interest rate risk. Borrowings under the Wells Fargo Term Loan bore interest at a per annum rate equal to Daily Three Month LIBOR plus an applicable margin. Our interest rate swap agreement bears interest of 1.00% less the per annum rate equal to Daily Three Month LIBOR, thus mitigating the interest rate risk associated with the Daily Three Month LIBOR and ensuring a fixed rate for hedged borrowings under the Wells Fargo Term Loan.

Our derivative instrument is held at fair value on our consolidated balance sheet. Related cash flows are recorded as operating activities on the consolidated statement of cash flows. Gains and losses related to this derivative instrument are recognized within other comprehensive income. As of December 31, 2013, the interest rate swap agreement was 100% effective, as interest for both the Wells Fargo Term Loan and interest rate swap agreement were calculated utilizing the Daily Three Month LIBOR rate on the same principal basis.

16. BUSINESS COMBINATION

Acquisition of Certain Assets from the Acro Group

On February 8, 2013, IES Renewable Energy, LLC (“IES Renewable”), an indirect wholly-owned subsidiary of the Company, entered into an Asset Purchase Agreement with a group of entities operating under the name of the Acro Group: Residential Renewable Technologies, Inc., Energy Efficiency Solar, Inc. and Lonestar Renewable Technologies Acquisition Corp. (collectively, the “Acro Group”). Pursuant to the terms of the Asset Purchase Agreement, the Company agreed to acquire certain assets in connection with the Acro Group’s turn-key residential solar integration business (the “Acquired Assets”). The Acquired Assets include, but are not limited to, assets relating to the Acro Group’s solar installation sales and marketing platform and the backlog of contracts entered into by the Acro Group with residential solar customers, which provide for the payment of sales and marketing fees in connection with the sale, installation and third-party financing of residential solar equipment. The transaction closed on February 15, 2013 (the “Closing Date”).

Following consummation of the transaction, IES Residential, Inc. (“IES Residential”), a wholly-owned subsidiary of the Company, began offering full-service residential solar integration services, including design, procurement, permitting, installation, financing services through third parties and warranty services for residential customers. IES Residential had previously provided solar installation subcontracting services to the Acro Group, and as of February 8, 2013, was owed $3,800 for subcontracting services provided up to that date (such balance, as of the day prior to the Closing Date, the “Accounts Receivable Balance”).

Total consideration received by the Acro Group for the Acquired Assets consisted of (i) IES Residential’s release of the Accounts Receivable Balance, (ii) payment by IES Renewable to the Acro Group of a percentage of future gross revenue generated from the Acquired Assets in an amount not to exceed $2,000 over the 12-month period beginning the first full month following the Closing Date, subject to certain reductions as described in the Asset Purchase Agreement, and (iii) $828 representing amounts paid by IES Residential, to the Acro Group to fund certain of its operating expenses between January 4, 2013 and the Closing Date.

Purchase price and fair value of assets acquired and liabilities assumed

The Company accounted for the transaction under the acquisition method of accounting, which requires recording assets and liabilities at fair value (Level 3). These Level 3 fair value assessments were measured based on a third party valuation, utilizing methodologies including discounted cash flow, replacement cost, and excess earnings. The total purchase price was allocated to the tangible assets and separately identifiable intangible assets acquired and liabilities assumed based on their fair values on the Closing Date.

The valuations were derived based on assumptions made by management. While management believes that its assumptions underlying the valuations are reasonable, different estimates and assumptions could result in different values being assigned to individual assets acquired and liabilities assumed. The fair value of assets acquired and liabilities assumed on the Closing Date is as follows:

Acquisition of MISCOR

On September 13, 2013 we completed the acquisition of 100% of the voting equity interests of MISCOR Group, Ltd. (“MISCOR”), a provider of maintenance and repair services including engine parts and components to the industrial and rail services. MISCOR operates in locations in Indiana, Alabama, Ohio, West Virginia, Maryland, and California. Following the consummation of the transaction, MISCOR represents the sole component of our Infrastructure Solutions segment.

Total consideration received by MISCOR shareholders consisted of 2,795,577 shares of IES common stock valued at $11,853, combined with cash totaling $4,364.

Purchase price and fair value of assets acquired and liabilities assumed

The Company accounted for the transaction under the acquisition method of accounting, which requires recording assets and liabilities at fair value (Level 3). These Level 3 fair value assessments were measured based on a third party valuation, utilizing methodologies including discounted cash flow, replacement cost, and excess earnings, which are subject to finalization. The total estimated purchase price was allocated to the tangible assets and separately identifiable intangible assets acquired and liabilities assumed based on their preliminary estimated fair values on September 13, 2013.

The valuations derived from estimated fair value assessments and assumptions used by management are preliminary pending finalization of certain intangible asset valuations. While management believes that its preliminary estimates and assumptions underlying the valuations are reasonable, different estimates and assumptions could result in different values being assigned to individual assets acquired and liabilities assumed. This may result in adjustments to the preliminary amounts recorded and goodwill, which could be material. The preliminary valuation of the assets acquired and liabilities assumed as of September 13, 2013 is as follows:

17. DISCONTINUED OPERATIONS

In 2011, we initiated the closure of all or portions of our Commercial & Industrial and Communications facilities in Arizona, Florida, Iowa, Louisiana, Maryland, Massachusetts, Nevada and Texas. These facilities were a key aspect of our commitment to return the Company to profitability and selected based on their current business prospects and the extended time frame needed to return the facilities to a profitable position. From the time of identification through December 31, 2013, we have sub-leased or terminated our lease contracts for leased facilities. We have satisfied substantially all of our contracts through either the subcontracting or self-performance. We have completed the wind down of these facilities as of December 31, 2013. Results from operations of these facilities for the three months ended December 31, 2013 and 2012 are presented in our Consolidated Statements of Comprehensive Income as discontinued operations.

The components of the results of discontinued operations for these facilities are as follows:

Included in the Consolidated Balance Sheets at December 31, 2013 and September 30, 2013 are the following major classes of assets and liabilities associated with discontinued operations:
