Item 1. Business

OVERVIEW OF OUR SERVICES

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

Our businesses are managed in a decentralized manner. While sharing common goals and values, each of the Company’s segments manages its own day-to-day operations. Our corporate office is focused on significant capital allocation decisions, investment activities and selection of segment leadership, as well as strategic and operational improvement initiatives and the establishment and monitoring of risk management practices within our segments.

Integrated Electrical Services, Inc. is a Delaware corporation established in 1997 and headquartered in Houston, Texas, with an executive office in Greenwich, Connecticut.

CORPORATE STRATEGY

We seek to create shareholder value through positive returns on capital and generation of free cash flow. In addition, we seek to acquire or invest in stand-alone platform companies based in North America or acquire businesses that strategically complement our existing business segments. In evaluating potential acquisition candidates, we seek to invest in businesses with, among other characteristics:

In furtherance of this strategy, during fiscal year 2015 we acquired 100% of the stock of a motor remanufacture business that is operated under our Infrastructure Solutions business, and in the first quarter of fiscal year 2016 we acquired 100% of the stock or membership interests in two businesses, one of which is a motor assembly and remanufacture business operated in our Infrastructure Solutions business and one of which is a mechanical and electrical contracting business operated in our Commercial & Industrial business. For more information on these acquisitions, please refer to Note 20, “Subsequent Events” in the notes to our Consolidated Financial Statements.

Table of Contents

We believe that acquisitions provide an opportunity to expand into new end markets and diversify our revenue and profit streams. Further, by acquiring businesses with net income, we expect to maximize the value of our significant net operating loss carry forwards (“NOLs”). While we may use acquisitions to build our presence in the industries we serve, we will also consider potential acquisitions in other industries, which could result in changes in our operations from those historically conducted by us.

Controlling Shareholder

A majority of our outstanding common stock is owned by Tontine Capital Partners, L.P. and its affiliates (collectively, “Tontine”). On October 15, 2015, Tontine filed an amended Schedule 13D indicating its ownership level of 62.2%. As a result, Tontine can control most of our affairs, including most actions requiring the approval of shareholders, such as the approval of any potential merger or sale of all or substantially all assets, segments, or the Company itself. Most of Tontine’s shares are registered on a shelf registration statement (the “Shelf Registration Statement”) filed by the Company and declared effective in 2013 by the U.S. Securities and Exchange Commission (the “SEC”). Tontine’s sale of all or any portion of its shares could result in a change of control, which would trigger the change of control provisions in a number of our material agreements, including our credit facility, bonding agreements with our sureties and our executive severance plan. For more information see Note 3, “Controlling Shareholder” in the notes to our Consolidated Financial Statements.

Net Operating Loss Carry Forward

The Company and certain of its subsidiaries have a federal NOL of approximately $439 million at September 30, 2015, including approximately $142 million resulting from the additional amortization of personal goodwill. A change in ownership, as defined by Internal Revenue Code Section 382, could reduce the availability of net operating losses for federal and state income tax purposes. Should Tontine sell or otherwise dispose of all or a portion of its position in IES, a change in ownership could occur. In addition, a change in ownership could result from the purchase of common stock by an existing or a new 5% shareholder as defined by Internal Revenue Code Section 382. Should a change in ownership occur, all net operating losses incurred prior to the change in ownership would be subject to limitation imposed by Internal Revenue Code Section 382, which would substantially reduce the amount of NOL currently available to offset taxable income. For more information see Item 8, “Financial Statements and Supplementary Data” of this Form 10-K.

On January 28, 2013, the Company implemented a tax benefit protection plan (the “NOL Rights Plan”) that was 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. The NOL Rights Plan was filed as an Exhibit to our Current Report on Form 8-K filed with the SEC on January 28, 2013 and any description thereof is qualified in its entirety by the terms of the NOL Rights Plan.

For additional financial information by segment, see Note 10, “Operating Segments” in the notes to our Consolidated Financial Statements.

Communications

Business Description

Originally established in 1984, our Communications segment is a leading provider of network infrastructure services for data centers and other mission critical environments. Services offered include the design, installation and maintenance of network infrastructure for the financial, medical, hospitality, government, high-tech manufacturing, educational and information technology industries including for Fortune 500 corporations. We also provide the design and installation of audio/visual, telephone, fire, wireless access 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 11 offices, including our Communications headquarters located in Tempe, Arizona, allowing dedicated onsite maintenance teams at our customers’ sites.

Industry Overview

Our Communications segment is driven by demand increases for computing and storage resources as a result of technology advancements and changes in data consumption patterns. While growth of the data center market has stabilized, we are continuing to expand our offerings in this market to broaden our customer base. Additionally, demand has been growing for our audio-visual and other building technology offerings. Nevertheless, due to economic, technological and other factors, there can be no assurance that demand will continue to increase.

Sales and Marketing

Our sales strategy relies on a concentrated business development effort, with centralized marketing programs and direct end-customer communications and relationships. Due to the mission critical nature of the facilities we service, our end-customers significantly rely upon our past performance record, technical expertise and specialized knowledge. A significant portion of our Communications business volume is generated from long-term, repeat customers, some of whom use IES as a preferred provider for major projects.

Our long-term strategy is to improve our position as a preferred mission critical solutions and services provider to large national corporations and strategic local companies. Key elements of our long-term strategy include continued investment in our employees’ technical expertise and expansion of our onsite maintenance and recurring revenue model as well as opportunistic acquisitions of businesses that serve our markets, consistent with our stated corporate strategy.

Competition

Our competition consists of both large public companies and small, privately owned contractors who have limited access to capital. We compete on quality of service and/or price, and seek to emphasize our long history of delivering high quality solutions to our customers.

Seasonality and Quarterly Fluctuations

The effects of seasonality on our Communications business are insignificant, as work generally is performed inside structures protected from the weather. Our service and maintenance business is also generally not affected by seasonality. However, communications infrastructure spending has historically been highly cyclical. Our volume of business may be adversely affected by declines in projects resulting from adverse regional or national economic conditions. Quarterly results may also be materially affected by the timing of new construction projects. Accordingly, operating results for any fiscal period are not necessarily indicative of results that may be achieved for any subsequent fiscal period.

Residential

Business Description

Originally established in 1973, our Residential segment is a leading provider of electrical installation services for single-family housing and multi-family apartment complexes and cable television (“CATV”) cabling installations for residential and light commercial applications. In addition to our core electrical construction work, the Residential segment also provides services for the installation of residential solar power, smart meters, and electric car charging stations, both for new construction and existing residences. The Residential segment is made up of 26 total locations, which include the headquarters in Houston, Texas. These locations geographically cover the Sun-Belt, and the Western and Mid-Atlantic regions of the United States.

Industry Overview

Our Residential business is closely correlated to the single and multi-family housing market. Demand for both single-family and multi-family housing has increased in recent years. Nevertheless, due to economic, technological or other factors there can be no assurance that construction and demand will continue to increase in the future.

Sales and Marketing

Demand for our Residential services is highly dependent on the number of single-family and multi-family home starts in the markets we serve. Although we operate in multiple states throughout the Sun-Belt, Mid-Atlantic and Western regions of the United States, the majority of our segment revenues are derived from services provided in the state of Texas. Our sales efforts include a variety of strategies, including a concentrated focus on national homebuilders and multi-family developers and a local sales strategy for single and multi-family housing projects. Our cable, solar and electric car charging station revenues are typically generated through third parties specializing in these industries who select us as a preferred provider of installation services. A significant portion of our Residential business volume is generated from long-term, repeat customers, some of whom use IES as a preferred provider for major projects.

Our long-term strategy is to continue to be the leading national provider of electrical services to the residential market. The key elements of our long-term strategy include a continued focus on maintaining a low and variable cost structure and cash generation which has allowed us to effectively scale according to the housing cycle. During the housing downturn, we modified our strategy by expanding into markets less exposed to national building cycles, such as solar panel and cable installation services.

Competition

Our competition primarily consists of small, privately owned contractors who have limited access to capital. We believe that we have a competitive advantage over these smaller competitors due to our key employees’ long-standing customer relationships, our financial capabilities, and our local market knowledge and competitive pricing. There are few barriers to entry for electrical contracting services in the residential markets.

Seasonality and Quarterly Fluctuations

Results of operations from our Residential segment can be seasonal, depending on weather trends, with typically higher revenues generated during spring and summer and lower revenues during fall and winter. 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. In particular, a prolonged period of low oil prices and subsequent slowdown in the economy could have a negative impact on demand for housing in regions such as Texas, which is a key market for us. Quarterly results may also be materially affected by the timing of new construction projects. Accordingly, operating results for any fiscal period are not necessarily indicative of results that may be achieved for any subsequent fiscal period.

Commercial & Industrial

Business Description

Our Commercial & Industrial segment offers a broad range of expertise that enables us to provide a wide array of quality services related to electrical design, construction, and maintenance to the commercial and industrial markets. The offerings under our design services platform range from budget assistance to providing design build and LEED (Leadership in Energy & Environmental Design) solutions to our end customers. These services are typically integrated with our construction services. Our construction services range from the initial planning and procurement to installation and start-up. The construction services are offered to a variety of new and remodel construction projects, including transmission and distribution projects. The maintenance services offered include critical plant shutdown, troubleshooting, emergency testing, preventative maintenance, and constant presence. This segment provides services for a variety of project types, including: office buildings, manufacturing facilities, data centers, chemical plants, refineries, wind farms, solar facilities and municipal infrastructure and health care facilities. The Commercial & Industrial segment consists of 19 total locations, which include the segment headquarters in Houston, Texas. These locations geographically cover Texas, Nebraska, Colorado, Oregon and the Mid-Atlantic region. On November 20, 2015, we expanded our geographic and service offerings with the acquisition of Shanahan Mechanical and Electrical, Inc., a Lincoln, Nebraska-based provider of mechanical and electrical contracting services, which will operate as a subsidiary in this segment.

Industry Overview

Given the diverse end markets of our Commercial & Industrial customers, which include both commercial buildings, such as offices, healthcare facilities and schools, and industrial projects, such as power, chemical, refinery and heavy manufacturing facilities, we are subject to many trends within the construction industry. In general, demand for our Commercial & Industrial services is driven by construction and renovation activity levels, economic growth, and availability of bank lending. Due to economic, technological or other factors, there can be no assurance that construction and demand will increase.

Sales and Marketing

Our sales focus varies by location, but is primarily based upon regional and local relationships and a demonstrated expertise in certain industries, such as transmission and distribution. Our maintenance and certain renovation and upgrade work tend to be either recurring or experience lower sensitivity to economic cycles, or both. A significant portion of our larger projects are awarded from long-term, repeat customers. From time to time, we are contracted on projects with completion times extending beyond one year or over several years, which are generally more complex and difficult to estimate.

With a focus on quality service offerings, our long-term strategy is to continue to be the one of the preferred providers of electrical services in the markets where we have demonstrated expertise and/or are a local market leader. Key elements of our long-term strategy include leveraging our expertise in certain niche markets, expansion of our service and maintenance business and maintaining our focus on our returns on risk adjusted capital.

Competition

The electrical infrastructure services industry is generally highly competitive and includes a number of regional or small privately-held local firms. There are few barriers to entry for our electrical contracting services in the commercial and industrial markets, which limits our advantages when competing for projects. Industry expertise, project size, location and past performance will determine our bidding strategy, the level of involvement from competitors and our level of success in winning awards. Our primary advantages vary by location and market, but mostly are based upon local individual relationships with key customers or a demonstrated industry expertise. Additionally, due to the size of many of our projects, our financial resources help us compete effectively against local competitors.

Seasonality and Quarterly Fluctuations

The effects of seasonality on our Commercial & Industrial business are insignificant, as work generally is performed inside structures protected from the weather. Our service and maintenance business is also generally not affected by seasonality. However, 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. Accordingly, operating results for any fiscal period are not necessarily indicative of results that may be achieved for any subsequent fiscal period.

Infrastructure Solutions

Business Description

Our Infrastructure Solutions segment provides electrical and mechanical solutions to domestic and international customers. Services include the maintenance and repair of alternating current (AC) and direct current (DC) electric motors and generators, as well as power generating and distribution equipment; the manufacture, remanufacture, and repair of industrial lifting magnets; and maintenance and repair of railroad main and auxiliary generators, main alternators, and traction motors. In addition, Infrastructure Solutions manufactures and remanufactures EMD-style power assemblies for various engine types and offers premium replacement parts for power assemblies, primarily for the railroad and marine markets. This segment serves steel, railroad, marine, petrochemical, pulp and paper, wind energy, mining, automotive, power generation, scrap yards, and utility industries. Infrastructure Solutions is comprised of 10 locations, headquartered in Ohio. These segment locations geographically cover Alabama, Georgia, Indiana, Ohio, West Virginia, Maryland and California. On October 30, 2015, we expanded our geographic and service offerings with the acquisition of Calumet Armature & Electric, LLC (“Calumet”), an Illinois-based provider of design, manufacturing, assembly, and repair services of electric motors for the industrial and mass transit markets, which will operate as a subsidiary in this segment.

Industry Overview

Given the diverse end-markets of Infrastructure Solutions’ customers, we are subject to many economic trends. In general, demand for our services has been driven by in-house maintenance departments continuing to outsource maintenance and repair work, output levels and equipment utilization at heavy industrial facilities, railroad companies’ capital investment in locomotives, and the overall health of the economy.

Sales and Marketing

Demand for Infrastructure Solutions’ services is largely driven by the degree to which industrial and mechanical services are outsourced by our customers, production rates at steel, power generation and other heavy industrial facilities, and the need for electrical infrastructure improvements. Our sales efforts are primarily driven by personnel based at our 10 locations and independent sales representatives. Given that the majority of our customers are located within a 200 mile radius of our facilities, we believe that this structure allows us to rapidly address and respond to the needs of our customers. Our long term strategy is to be the preferred provider of outsourced electro-mechanical services, repairs, and manufacturing to our select markets and a trusted provider of aftermarket EMD-style power assemblies.

Competition

Our competition is comprised mainly of small, specialized manufacturing and repair shops, a limited number of other multi-location providers of electric motor repair, engineering and maintenance services, and various original equipment manufacturers. Participants in this industry compete primarily on the basis of capabilities, service, quality, timeliness and price. We believe that we have a competitive advantage over most small service providers due to our breadth of capabilities, focus on quality, technical support and customer service.

Table of Contents

Seasonality and Quarterly Fluctuations

Infrastructure Solutions’ revenues from industrial services may be affected by the timing of scheduled outages at its industrial customers’ facilities and by weather conditions with respect to projects conducted outdoors, but the effects of seasonality on revenues in its industrial services business are insignificant. Rail spending is generally highly cyclical, which can impact our results in this segment, although we expect our newer transit traction motor offerings to be less impacted by cyclicality than our overall rail business. Infrastructure Solutions’ quarterly results may fluctuate, and the results of one fiscal quarter may not be representative of the results of any other quarter or of the full fiscal year.

SOURCES OF SUPPLY

The raw materials and components we use within our segments include, but are not limited to, electrical fixtures and system components, copper, aluminum, and raw steel. These raw materials and components are generally available from a variety of domestic suppliers at competitive prices. Delivery times are typically short for most raw materials and standard components, but during periods of peak demand, may extend to one month or more. Our strategy to reduce commodity cost exposure includes early buying of commodities for particular projects, or for general inventory, as well as including escalation and escape provisions in project bids, quotes and contracts wherever possible.

RISK MANAGEMENT

The primary risks in our existing operations include project bidding and management, bodily injury, property and environmental damage, and construction defects. We monitor project bidding and management practices at various levels within our company. We maintain automobile, general liability and construction defect insurance for third party health, bodily injury and property damage, pollution coverage and workers’ compensation coverage, which we consider appropriate to insure against these risks. Our third-party insurance is subject to deductibles for which we establish reserves. In light of these risks, we are also committed to a strong safety and environmental compliance culture. We employ full-time and part-time regional safety managers, under the supervision of our full-time Vice President of Safety, and seek to maintain standardized safety and environmental policies, programs, procedures and personal protection equipment relative to each segment, including programs to train new employees, which apply to employees new to the industry and those new to the Company. To further emphasize our commitment to safety, we have also tied certain management incentives to specific safety performance results.

In the electrical contracting industry, our ability to post surety bonds provides us with an advantage over competitors that are smaller or have fewer financial resources. We believe that the strength of our balance sheet, as well as a good relationship with our bonding providers, enhances our ability to obtain adequate financing and surety bonds. For a further discussion of our risks, please refer to Item 1A. “Risk Factors” of this Form 10-K.

CUSTOMERS

We have a diverse customer base. During the twelve-month periods ended September 30, 2015, 2014 and 2013, no single customer accounted for more than 10% of our consolidated revenues. We emphasize developing and maintaining relationships with our customers by providing superior, high-quality service. Management at each of our segments is responsible for determining sales strategies and sales activities.

BACKLOG

Backlog is a measure of revenue that we expect to recognize from work that has yet to be performed on uncompleted contracts, and from work that has been contracted but has not started, exclusive of short-term projects. While all of our backlog is supported by documentation from customers authorizing the performance of future work, backlog is not a guarantee of future revenues, as contractual commitments may change. Not all of our work is performed under contracts included in backlog; for example, most work performed by our Infrastructure Solutions segment is performed under master service agreements on an as-needed basis. The table below summarizes our backlog by segment:

REGULATIONS

Our operations are subject to various federal, state and local laws and regulations, including:

Many state and local regulations governing electricians require permits and licenses to be held by individuals. In some cases, a required permit or license held by a single individual may be sufficient to authorize specified activities for all our electricians who work in the state or county that issued the permit or license. It is our policy to ensure that, where possible, any permits or licenses that may be material to our operations in a particular geographic area are held by multiple employees within that area.

We believe we have all licenses required to conduct our operations and are in compliance with applicable regulatory requirements. Failure to comply with applicable regulations could result in substantial fines or revocation of our operating licenses or an inability to perform government work.

CAPITAL FACILITIES

During fiscal year 2015, the Company maintained a credit facility, as described in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — The 2012 Revolving Credit Facility” of this Form 10-K. For a discussion of the Company’s capital resources, see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources” of this Form 10-K.

Item 1A. Risk Factors

You should consider carefully the risks described below, as well as the other information included in this document before making an investment decision. Our business, results of operations or financial condition could be materially and adversely affected by any of these risks, and the value of your investment may decrease due to any of these risks.

Existence of a controlling shareholder.

A majority of our outstanding common stock is owned by Tontine Capital Partners, L.P. and its affiliates (collectively, “Tontine”). On October 15, 2015, Tontine filed an amended Schedule 13D indicating its ownership level of 62.2%. As a result, Tontine can control most of our affairs, including the election of our directors, who in turn appoint executive management, and can control most actions requiring the approval of shareholders, including the adoption of amendments to our corporate charter and approval of any potential merger or sale of all or substantially all assets, segments, or the Company itself. This control also gives Tontine the ability to bring matters to a shareholder vote that may not be in the best interest of our other shareholders or stakeholders. Additionally, Tontine is in the business of investing in companies and may, from time to time, acquire and hold interests in businesses that compete directly or indirectly with us or act as suppliers or customers of the Company. Pursuant to a shelf registration statement that was declared effective by the SEC on June 18, 2013, Tontine has the ability to resell any or all of its registered shares from time to time in one or more offerings as long as the shelf registration statement remains effective, as described further in the shelf registration statement and in any prospectus supplement filed in connection with an offering pursuant to the shelf registration statement. Tontine’s sale of all or any portion of its shares could result in a change of control, which would trigger the change of control provisions in a number of our material agreements, including our credit facility, bonding agreements with our sureties and our executive severance plan.

Although publicly traded, our common stock has lower trading volume than many other stocks listed on the NASDAQ Global Market.

The trading volume in our common stock on the NASDAQ Global Market has been relatively low when compared with larger companies listed on the NASDAQ Global Market or other stock exchanges. Although we have at times experienced increased liquidity in our stock, we cannot say with any certainty that a more active and liquid trading market for our common stock will continue to develop. Because of this, it may be more difficult for shareholders to sell a substantial number of shares for the same price at which shareholders could sell a smaller number of shares.

We cannot predict the effect, if any, that future sales of our common stock in the market, or the availability of shares of our common stock for sale in the market, will have on the market price of our common stock. We can give no assurance that sales, or potential sales, of substantial amounts of our common stock in the market would not cause the price of our common stock to decline or impair our future ability to raise capital through sales of our common stock.

The market price of our common stock may fluctuate in the future, and this volatility may be unrelated to our performance. General market price declines or overall market volatility in the future could adversely affect the price of our common stock, and the current market price may not be indicative of future market prices.

We may issue additional shares of common stock or convertible securities that will dilute the percentage ownership interest of existing stockholders and may dilute the book value per share of our common stock.

Our authorized capital includes 100,000,000 shares of common stock and 10,000,000 shares of preferred stock. As of September 30, 2015, we had 21,475,741 shares of common stock outstanding and no shares of preferred stock outstanding. We have reserved for issuance 133,000 shares of common stock underlying options that are exercisable at a weighted average price of $5.79 per share. In addition, as of September 30, 2015 we had the ability to issue 472,054 shares of common stock pursuant to options and restricted stock that may be granted in the future under our existing equity compensation plans.

Table of Contents

Although we currently do not have any intention of issuing additional common stock (other than pursuant to our equity compensation plans), we may do so in the future in order to meet our capital needs. Subject to applicable NASDAQ Listing Rules, our board of directors generally has the authority, without action by or vote of the stockholders, to issue all or part of any authorized but unissued shares of common stock for any corporate purpose. We may seek additional equity capital in the future as we develop our business and expand our operations. Any issuance of additional shares of common stock or convertible securities will dilute the percentage ownership interest of our stockholders and may dilute the book value per share of our common stock.

Substantial sales of our common stock could adversely affect our stock price.

Sales of a substantial number of shares of our common stock by holders of our common stock, or the perception that such sales could occur, could adversely affect the market price of our common stock by introducing a large number of shares into the market. Such sales, or the perception that such sales could occur, could cause the market price of our common stock to decline. We cannot predict whether future sales of our common stock, or the availability of our common stock for sale, will adversely affect the market price for our common stock or our ability to raise capital by offering equity securities.

Availability of net operating losses may be reduced by a change in ownership.

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. 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 could also result from the purchase of common stock by an existing or a new 5% shareholder as defined by Internal Revenue Code Section 382. As of September 30, 2015, we have approximately $297 million of federal NOLs that are available to use to offset taxable income, exclusive of NOLs from the amortization of additional tax goodwill. Should a change in ownership occur, all NOLs incurred prior to the change in ownership would be subject to limitation imposed by Internal Revenue Code Section 382, which would substantially reduce the amount of NOL currently available to offset taxable income.

On January 28, 2013, we implemented the NOL Rights Plan, which was 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. The NOL Rights Plan is designed to effectively dilute the ownership of such an acquirer through the offering of rights to the Company’s other stockholders that could be exercised upon the acquirer’s purchase of the Company’s stock in excess of the threshold amount. We can make no assurances the NOL Rights Plan will be effective in deterring a change in control or protecting or realizing NOLs.

Any decrease in the federal statutory tax rate, or other changes in federal tax statutes, could also cause a reduction in the economic benefit of the NOL currently available to us.

Our inability to carry out plans and strategies as expected, including our inability to identify and complete acquisitions that meet our investment criteria in furtherance of our corporate strategy, may adversely impact our future growth.

Our corporate strategy involves creating shareholder value through acquiring or investing in stand-alone platform companies based in North America or acquiring businesses that we believe will strategically complement our existing business segments. While we believe that acquisitions will provide an opportunity to expand into new end markets and diversify our revenue and profit streams, potential acquisitions in new industries could result in changes in our operations from those historically conducted by us and introduce the requirement for new controls, and our failure to diversify from existing markets may limit our future growth. Further, our inability to carry out our acquisition strategy, or other plans and strategies, as expected could adversely impact our ability to maximize the value of our significant NOLs and or even to utilize our NOLs.

To service our indebtedness and to fund working capital, we will require a significant amount of cash. Our ability to generate cash depends on many factors that are beyond our control.

Our ability to make payments on and to refinance our indebtedness and to fund working capital requirements will depend on our ability to generate cash in the future. This is subject to our operational performance, as well as general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

We cannot provide assurance that our business will generate sufficient cash flow from operations or asset sales or that future borrowings will be available to us under our credit facility in an amount sufficient to enable us to pay our indebtedness or to fund our other liquidity needs. We may need to refinance all or a portion of our indebtedness, on or before maturity. We cannot provide assurance that we will be able to refinance any of our indebtedness on commercially reasonable terms, or at all. Our inability to refinance our debt on commercially reasonable terms could have a material adverse effect on our business.

We have restrictions and covenants under our credit facility.

We may not be able to remain in compliance with the covenants in our credit facility. A failure to fulfill the terms and requirements of our credit facility may result in a default under one or more of our material agreements, which could have a material adverse effect on our ability to conduct our operations and our financial condition.

The highly competitive nature of our industries could affect our profitability by reducing our profit margins.

With respect to electrical contracting services, the industries in which we compete are highly fragmented and are served by many small, owner-operated private companies. There are also several large private regional companies and a small number of large public companies from which we face competition in these industries. In the future, we could also face competition from new competitors entering these markets because certain segments, such as our electrical contracting services, have a relatively low barrier for entry while other segments, such as our services for mission critical infrastructure, have attractive dynamics. Some of our competitors offer a greater range of services, including mechanical construction, facilities management, plumbing and heating, ventilation and air conditioning services. Competition in our markets depends on a number of factors, including price. Some of our competitors may have lower overhead cost structures and may, therefore, be able to provide services comparable to ours at lower rates than we do. If we are unable to offer our services at competitive prices or if we have to reduce our prices to remain competitive, our profitability would be impaired.

The markets in which Infrastructure Solutions does business are highly competitive, and we do not expect the level of competition that we face to decrease in the future. An increase in competitive pressures in these markets or our failure to compete effectively (including managing efficiently future capital expenditures and refurbishment, repair and upgrade costs) may result in pricing reductions, reduced gross margins, and loss of market share. Many of our competitors have longer operating histories, greater name recognition, more customers, and significantly greater financial, marketing, technical, and other competitive resources than we have. These competitors may be able to adapt more quickly to new technologies and changes in customer needs or devote greater resources to the development, promotion, and sale of their services. While we believe Infrastructure Solutions’ overall product and service offerings distinguish it from its competitors, these competitors could develop new products or services that could directly compete with Infrastructure Solutions’ services.

A failure to secure new contracts may adversely affect our cash flows and financial results.

Much of our revenue is derived from projects that are awarded through a competitive bid process. Contract bidding and negotiations are affected by a number of factors, including our own cost structure and bidding policies. In addition, our ability to secure new contracts depends on our ability to maintain all required electrical, construction and business licenses. If we fail to successfully transfer, renew or obtain such licenses where applicable, we may be unable to compete for new business.

17

Table of Contents

The failure to bid and be awarded projects, cancellations of projects or delays in project start dates could affect our ability to deploy our assets profitably. Further, when we are awarded contracts, we face additional risks that could affect whether, or when, work will begin. We could experience a decrease in profitability if we are unable to replace canceled, completed or expired contracts with new work.

We may be unsuccessful at integrating other companies that we may acquire, or new types of work, products or processes into our segments.

We are actively seeking to engage in acquisitions of operations, assets and investments, or to develop new types of work or processes, and we may seek to engage in dispositions of certain operations, assets or investments from time to time. If we are unable to successfully integrate newly acquired assets or operations or if we make untimely or unfavorable investments or dispositions, it could negatively impact the market value of our common stock. Additionally, any future acquisition, investment or disposition may result in significant changes in the composition of our assets and liabilities, and as a result, our financial condition, results of operations and the market value of our common stock following any such acquisition, investment or disposition may be affected by factors different from those currently affecting our financial condition, results of operations and market value of our common stock.

The difficulties of integrating a business, assets or operations potentially will include, among other things:

Demand for our services is cyclical and vulnerable to economic downturns affecting the industries we serve.

Demand for our services has been, and will likely continue to be, cyclical in nature and vulnerable to downturns in the general economy and in the construction industry. Many of our customers depend on the availability of credit to purchase our services or electrical and mechanical products. Prolonged uncertainties or the return of constrained credit market conditions could have adverse effects on our customers, which would adversely affect our financial condition and results of operations.

Backlog may not be realized or may not result in profits.

Customers often have no obligation under our contracts to assign or release work to us, and many contracts may be terminated on short notice. Reductions in backlog due to cancellation of one or more contracts by a customer or for other reasons could significantly reduce the revenue and profit we actually receive from contracts included in backlog. In the event of a project cancellation, we may be reimbursed for certain costs, but typically have no contractual right to the total revenues reflected in our backlog.

Our use of percentage-of-completion accounting could result in a reduction or elimination of previously reported profits; we may be adversely impacted by new accounting, control and operating procedures.

A significant portion of our revenues are recognized using the percentage-of-completion method of accounting, utilizing the cost-to-cost method, which results in our recognizing contract revenues and earnings ratably over the contract term in proportion to our incurrence of contract costs. The earnings or losses recognized on individual

18

Table of Contents

contracts are based on estimates of contract revenues, costs and profitability. We review our estimates of contract revenue, costs and profitability on an ongoing basis. Prior to contract completion, we may adjust our estimates on one or more occasions as a result of change orders to the original contract, collection disputes with the customer on amounts invoiced or claims against the customer for increased costs incurred by us due to customer-induced delays and other factors. Contract losses are recognized in full when determined to be probable and reasonably estimable. Although we have historically made reasonably reliable estimates of the progress towards completion of our construction contracts, the uncertainties inherent in the estimating process make it possible for actual costs to vary materially from estimates, including reductions or reversals of previously recorded revenues and profits. In addition, we may be adversely impacted by new accounting pronouncements which change our revenue recognition or other accounting practices or otherwise alter how we report our financial results, or which require that we change our control and operating procedures, which we may be unable to do in a timely manner.

We may incur significant charges or be adversely impacted by the closure or sale of facilities or assets.

In the past, we incurred significant costs associated with the closure or disposition of facilities, and we expect from time to time to evaluate the need for future facility closures or dispositions of assets. If we were to elect to dispose of a substantial portion of any of our segments, facilities, or assets, the realized values of such actions could be substantially less than current book values, which would likely result in a material adverse impact on our financial results. In addition, we may have warranty claims or other unexpected liabilities from closed facilities beyond the closing date, which could adversely impact our financial returns.

The availability and cost of surety bonds affect our ability to enter into new contracts and our margins on those engagements.

Many of our customers require us to post performance and payment bonds issued by a surety. Those bonds guarantee the customer that we will perform under the terms of a contract and that we will pay subcontractors and vendors. We obtain surety bonds from two primary surety providers; however, there is no commitment from these providers to guarantee our ability to issue bonds for projects as they are required. Our ability to access this bonding capacity is at the sole discretion of our surety providers. Accordingly, if we were to experience an interruption or reduction in our availability of bonding capacity, we may be unable to compete for, or work on, certain projects.

Due to seasonality and differing regional economic conditions, our results may fluctuate from period to period.

Our business is subject to seasonal variations in operations and demand that affect the construction business, particularly in the Residential and Commercial & Industrial segments, as well as seasonal variations in the industrial and rail industries in which Infrastructure Solutions participates. Untimely weather delay from rain, heat, ice, cold or snow can not only delay our work but can negatively impact our schedules and profitability by delaying the work of other trades on a construction site. Our quarterly results may also be affected by regional economic conditions that affect the construction market. In particular, a prolonged period of weak demand in the oil and gas industry could dampen the housing market in certain regions, resulting in reduced demand for the services provided by our Residential segment. Infrastructure Solutions’ revenues from industrial services may be affected by the timing of scheduled outages at its industrial customers’ facilities and by weather conditions with respect to projects conducted outdoors. Industrial and rail customers may also be affected by continuing low oil prices. Accordingly, our performance in any particular quarter may not be indicative of the results that can be expected for any other quarter or for the entire year.

The estimates we use in placing bids could be materially incorrect. The use of incorrect estimates could result in reduced profits or in some cases losses on fixed price contracts.

We currently generate, and expect to continue to generate, a significant portion of our revenues under fixed price contracts. The cost of fuel, labor and materials, including copper wire or other commodities, may vary significantly from the costs we originally estimate. Variations from estimated contract costs along with other

19

Table of Contents

risks inherent in performing fixed price contracts, including our ability to successfully manage projects, may result in actual revenue and gross profits for a project differing from those we originally estimated, and could result in losses on projects. Depending upon the size of a particular project, variations from estimated contract costs can have a significant impact on our operating results.

Commodity and labor costs may fluctuate materially, and we may not be able to pass on all cost increases during the term of a contract, which could have an adverse effect on our ability to maintain our profitability.

We enter into many contracts at fixed prices, and if the costs associated with labor; and commodities such as copper, aluminum, steel, fuel and certain plastics increase, losses may be incurred. Some of these materials have been and may continue to be subject to sudden and significant price increases. Depending on competitive pressures and customer resistance, we may not be able to pass on these cost increases to our customers, which would reduce our gross profit margins and, in turn, make it more difficult for us to maintain our profitability.

Changes in operating factors that are beyond our control could hurt our operating results.

Our operating results may fluctuate significantly in the future as a result of a variety of factors, many of which are beyond management’s control. These factors include the costs of new technology; the relative speed and success with which Infrastructure Solutions can acquire customers for its products and services; capital expenditures for equipment; sales, marketing, and promotional activities expenses; changes in its pricing policies, suppliers, and competitors; changes in operating expenses; increased competition in the markets we serve; changes in regulations; and other general economic and seasonal factors. Adverse changes in one or more of these factors could hurt our operating results.

We may experience difficulties in managing our billings and collections.

Our billings under fixed price contracts in our electrical contracting business are generally based upon achieving certain milestones and will be accepted by the customer once we demonstrate those milestones have been met. If we are unable to demonstrate compliance with billing requests, or if we fail to issue a project billing, our likelihood of collection could be delayed or impaired, which, if experienced across several large projects, could have a materially adverse effect on our results of operations. Further, some of our customers may be highly leveraged, or may be subject to their own operating and regulatory risks, which may also limit their ability to pay.

Our reported operating results could be adversely affected as a result of goodwill impairment charges.

Accounting principles generally accepted in the United States of America (“GAAP”) require that goodwill attributable to each of our reporting units be tested at least annually, or when changes in circumstance indicate the carrying value of our reporting units may not be recoverable. Factors that could lead to impairment of goodwill include significant adverse changes in the business climate, declines in the financial condition of our business, and actual or projected operating results affecting our company as a whole or affecting any particular reporting unit. On an ongoing basis, we expect to perform impairment tests at least annually as of September 30. Impairment adjustments, if any, are required to be recognized as operating expenses. We cannot assure that we will not have future impairment adjustments to our recorded goodwill.

The vendors who make up our supply chain may be adversely affected by the current operating environment and credit market conditions.

We are dependent upon the vendors within our supply chain to maintain a steady supply of inventory, parts and materials. Many of our segments are dependent upon a limited number of suppliers, and significant supply disruptions could adversely affect our operations. If market conditions deteriorate, such as a slowdown in construction activity or a tightening of the credit market, it is possible that one or more of our suppliers will be unable to meet the terms of our operating agreements due to financial hardships, liquidity issues or other reasons related to market conditions.

Our operations are subject to numerous physical hazards. If an accident occurs, it could result in an adverse effect on our business.

Hazards related to our industry include, but are not limited to, electrocutions, fires, machinery-caused injuries, mechanical failures and transportation accidents. These hazards can cause personal injury and loss of life, severe damage to or destruction of property and equipment, and may result in suspension of operations. Our insurance does not cover all types or amounts of liabilities. In addition, if our safety record were to substantially deteriorate over time, our customers could cancel our contracts or not award us future business.

Our current insurance coverage may not be adequate, and we may not be able to obtain insurance at acceptable rates, or at all.

Our third-party insurance is subject to deductibles for which we establish reserves. No assurance can be given that our insurance or our provisions for incurred claims and incurred but not reported claims will be adequate to cover all losses or liabilities we may incur in our operations; nor can we provide assurance that we will be able to maintain adequate insurance at reasonable rates.

Our internal controls over financial reporting and our disclosure controls and procedures may not prevent all possible errors that could occur. Internal controls over financial reporting and disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objective will be met.

On a quarterly basis we evaluate our internal controls over financial reporting and our disclosure controls and procedures, which include a review of the objectives, design, implementation and effectiveness of the controls and the information generated for use in our periodic reports. In the course of our controls evaluation, we sought (and seek) to identify data errors, control problems and to confirm that appropriate corrective actions, including process improvements, are being undertaken. This type of evaluation is conducted on a quarterly basis so that the conclusions concerning the effectiveness of our controls can be reported in our periodic reports.

A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be satisfied. Internal controls over financial reporting and disclosure controls and procedures are designed to give reasonable assurance that they are effective and achieve their objectives. We cannot provide absolute assurance that all possible future control issues have been detected. These inherent limitations include the possibility that our judgments can be faulty, and that isolated breakdowns can occur because of human error or mistake. The design of our system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed absolutely in achieving our stated goals under all potential future or unforeseeable conditions. Because of the inherent limitations in a cost-effective control system, misstatements due to error could occur without being detected.

We have adopted tax positions that a taxing authority may view differently. If a taxing authority differs with our tax positions, our results may be adversely affected.

Our effective tax rate and cash paid for taxes are impacted by the tax positions that we have adopted. Taxing authorities may not always agree with the positions we have taken. We have established reserves for tax positions that we have determined to be less likely than not to be sustained by taxing authorities. However, there can be no assurance that our results of operations will not be adversely affected in the event that disagreement over our tax positions does arise.

Litigation and claims can cause unexpected losses.

In the construction business there are frequently claims and litigation. There are also inherent claims and litigation risks associated with the number of people that work on construction sites and the fleet of vehicles on the road every day. In all of our businesses, we are subject to potential claims and litigation. Claims are

21

Table of Contents

sometimes made and lawsuits filed for amounts in excess of their value or in excess of the amounts for which they are eventually resolved. Claims and litigation normally follow a predictable course of time to resolution. However, there may be periods of time in which a disproportionate amount of our claims and litigation are concluded in the same quarter or year. If multiple matters are resolved during a given period, then the cumulative effect of these matters may be higher than the ordinary level in any one reporting period.

Latent defect claims could expand.

Latent defect litigation is normal for residential home builders in some parts of the country; however, such litigation is increasing in certain states where we perform work. Also, in recent years, latent defect litigation has expanded to aspects of the commercial market. Should we experience similar increases in our latent defect claims and litigation, additional pressure may be placed on the profitability of the Residential and Commercial & Industrial segments of our business.

Interruptions in the proper functioning of our information systems, or security breaches of our information systems or confidential data could disrupt operations and cause increases in costs and/or decreases in revenues.

As our Company continues to increase its dependence on information technology systems, networks, and infrastructure to conduct its day to day operations, the proper functioning and security of our information technology environment is critical to the successful operation of our business. Although our information systems, networks and infrastructure are protected through physical and software safeguards, our information technology environment is still vulnerable to natural disasters, power losses, telecommunication failures, cybersecurity risks, and other problems, which could cause a loss of data, release of personally identifiable information or release of confidential customer information among other items. If critical information systems fail or are otherwise unavailable or confidential information is released, our business operations could be adversely affected.

We may be required to conduct environmental remediation activities, which could be expensive and inhibit the growth of our business and our ability to maintain profitability, particularly in our Infrastructure Solutions business.

We are subject to a number of environmental laws and regulations, including those concerning the handling, treatment, storage, and disposal of hazardous materials. These laws predominantly affect our Infrastructure Solutions business but may impact our other businesses. These environmental laws generally impose liability on present and former owners and operators, transporters and generators of hazardous materials for remediation of contaminated properties. We believe that our business is operating in compliance in all material respects with applicable environmental laws, many of which provide for substantial penalties for violations. There can be no assurance that future changes in such laws, interpretations of existing regulations or the discovery of currently unknown problems or conditions will not require substantial additional expenditures. In addition, if we do not comply with these laws and regulations, we could be subject to material administrative, civil or criminal penalties, or other liabilities. We may also be required to incur substantial costs to comply with current or future environmental and safety laws and regulations. Any such additional expenditures or costs that we may incur could hurt our operating results.

The loss of a group or several key personnel, either at the corporate or operating level, could adversely affect our business.

The loss of key personnel or the inability to hire and retain qualified employees could have an adverse effect on our business, financial condition and results of operations. Our operations depend on the continued efforts of our executive officers, senior management and management personnel at our segments. We cannot guarantee that any member of management at the corporate or subsidiary level will continue in their capacity for any particular

22

Table of Contents

period of time. We have a severance plan in place that covers certain of our senior leaders; however, this plan can neither guarantee that we will not lose key employees, nor prevent them from competing against us, which is often dependent on state and local employment laws. If we lose a group of key personnel or even one key person at a segment, we may not be able to recruit suitable replacements at comparable salaries or at all, which could adversely affect our operations. Additionally, we generally do not maintain key man life insurance for members of our management.

Item 5. Market for Registrant’s Common Equity; Related Stockholder Matters and Issuer Purchases of Equity Securities

Our common stock trades on the NASDAQ Global Select Market under the ticker symbol “IESC.” The following table sets forth the daily high and low close price for our common stock as reported on NASDAQ for each of the four quarters of the fiscal years ended September 30, 2015 and 2014.

As of December 9, 2015, the closing market price of our common stock was $7.63 per share and there were approximately 384 holders of record.

We have never paid cash dividends on our common stock and we do not anticipate paying cash dividends in the foreseeable future. We expect that we will utilize all available earnings generated by our operations and borrowings under the 2012 Credit Facility (as defined herein) for the development and operation of our business, to retire existing debt, to repurchase our common stock, or to acquire or invest in other businesses. Any future determination as to the payment of dividends will be made at the discretion of our Board of Directors and will depend upon our operating results, financial condition, capital requirements, general business conditions and other factors that the Board of Directors deems relevant. Our debt instruments restrict us from paying cash dividends and also place limitations on our ability to repurchase our common stock. See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Working Capital” and Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” of this Form 10-K.

Stock Repurchase Plan

On February 4, 2015, our Board of Directors authorized a stock repurchase program for purchasing up to 1.0 million shares of the Company’s common stock from time to time, and on December 9, 2015 authorized repurchase of an additional 500,000 shares. Share purchases are made for cash in open market transactions at prevailing market prices or in privately negotiated transactions or otherwise. The timing and amount of purchases under the program are determined based upon prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. All or part of the repurchases may be implemented under a Rule 10b5-1 trading plan, which allows repurchases under pre-set terms at times when the Company might otherwise be prevented from purchasing under insider trading laws or because of self-imposed blackout periods. The program does not require the Company to purchase any specific number of shares and may be modified, suspended or reinstated at any time at the Company’s discretion and without notice. During the year ended September 30, 2015, pursuant to the program, the Company repurchased 482,156 shares of common stock at an average of $7.22 per share for a total aggregate purchase price of $3.5 million.

OVERVIEW

Executive Overview

Please refer to Item 1. “Business” of this Form 10-K for a discussion of the Company’s services and corporate strategy. Integrated Electrical Services, Inc., a Delaware corporation, is a holding company that owns and manages diverse operating subsidiaries, comprised of providers of industrial infrastructure services to a variety of end markets. Our operations are currently organized into four principal business segments: Communications, Residential, Commercial & Industrial, and Infrastructure Solutions.

Industry Trends

Our performance is affected by a number of trends that drive the demand for our services. In particular, the markets in which we operate are exposed to many regional and national trends such as the demand for single and multi-family housing, the need for mission critical facilities as a result of technology-driven advancements, the degree to which in-house maintenance departments outsource maintenance and repair work, output levels and equipment utilization at heavy industrial facilities, demand for our railroad locomotive parts, and changes in commercial, institutional, public infrastructure and electric utility spending. Over the long term, we believe that there are numerous factors that could positively drive demand and affect growth within the industries in which we operate, including (i) population growth, which will increase the need for commercial and residential facilities, (ii) aging public infrastructure, which must be replaced or repaired, (iii) increased emphasis on environmental and energy efficiency, which may lead to both increased public and private spending, and (iv) the low price of natural gas which is expected to spur the construction of and modifications to heavy industrial facilities. However, there can be no assurance that we will not experience a decrease in demand for our services due to economic, technological or other factors, including the slowdown in the oil and gas sector, which may reduce the demand for housing in the Texas region, where our Residential division operates. For a further discussion of the industries in which we operate, please see Item 1. “Business—Operating Segments” of this Form 10-K.

Business Outlook

While differences exist among the Company’s segments, on an overall basis, demand for the Company’s services increased in fiscal 2015 as compared to fiscal 2014, resulting in aggregate year-over-year revenue growth. In addition, the Company’s previous investment in growth initiatives and other business-specific factors discussed below contributed to year-over-year revenue growth. Among our segments, year-over-year revenue growth rates during fiscal 2015 were led primarily by growth in our Communications segment followed closely by our Residential segment. The combination of increasing revenue, increasing project bid margins, effective project

execution, and efficient scaling of operations as the economy improves have resulted in a year over year increase in profitability. Provided that no significant deterioration in general economic conditions occurs, the Company expects total revenues from existing businesses to increase on a year-over-year basis during fiscal 2016 due to an increase in overall demand for the services we provide. Despite this expectation of growth within certain segments, we remain focused on controlled growth within certain markets which continue to experience highly competitive margins and increasing costs.

To continue to grow our business, including through acquisitions, and to fund working capital, we may require a significant amount of cash. Our ability to generate cash depends on many factors that are beyond our control, including demand for our services, the availability of projects at margins acceptable to us, the ultimate collectability of our receivables, our ability to borrow on our 2012 Credit Facility, and our ability to raise funds in the capital markets, among many other factors. We anticipate that the combination of cash on hand, cash flows from operations and available capacity under our 2012 Credit Facility will provide sufficient cash to enable us to meet our working capital needs, debt service requirements and capital expenditures for property and equipment through the next twelve months. We expect that our fixed asset requirements will range from $2.0 to $3.0 million for the fiscal year ending on September 30, 2016, and we may acquire these assets either through capital expenditures or through lease agreements.

RESULTS OF OPERATIONS

We report our operating results across our four operating segments: Communications, Residential, Commercial & Industrial and Infrastructure Solutions. Expenses associated with our Corporate office are classified as a fifth segment. The following table presents selected historical results of operations of IES. The Infrastructure Solutions segment was added in connection with the acquisition of MISCOR Group, Ltd. in September 2013.

Consolidated revenues for the year ended September 30, 2015 were $61.5 million greater than for the year ended September 30, 2014, an increase of 12.0%. Revenues increased as both the Communications and Residential segments recognized double digit revenue growth driven by an increase in demand for their service offerings

combined with continued improvement of conditions in the markets in which they operate. The Commercial and Industrial segment also contributed to the overall year over year growth while the Infrastructure Solutions segment reported a minor decline in revenue, primarily due to a decrease in demand for power assemblies by certain of our large rail customers.

Our overall gross profit percentage increased to 17.4% during the year ended September 30, 2015 as compared to 16.2% during the year ended September 30, 2014. Gross profit as a percentage of revenue increased at all of our operating segments. This was primarily accomplished through improved project execution combined with a favorable mix of projects in progress and other services in demand.

Selling, general and administrative expenses include costs not directly associated with performing work for our customers. These costs consist primarily of compensation and benefits related to corporate, segment and branch management (including incentive-based compensation), occupancy and utilities, training, professional services, information technology costs, consulting fees, travel and certain types of depreciation and amortization. We allocate certain corporate selling, general and administrative costs across our segments as we believe this more accurately reflects the costs associated with operating each segment.

During the year ended September 30, 2015, our selling, general and administrative expenses were $81.4 million, an increase of $5.8 million, or 7.7%, as compared to the year ended September 30, 2014. The increase is primarily attributable to higher personnel costs in connection with the growth and increased profitability in our Communication and Residential segments. These increases were partially offset by a $1.0 million reduction in acquisition related costs and professional fees for the year ended September 30, 2015 compared to the year ended September 30, 2014.

Communications

2015 Compared to 2014

Revenue. Revenues increased by $25.8 million during the year ended September 30, 2015, a 22.2% increase compared to the year ended September 30, 2014. The increase is the result of both the expansion of our customer base and additional work with existing customers. The expansion of our service offerings within areas such as Voice over Internet Protocol (VoIP) resulted in $10.8 million of incremental revenue for the year ended September 30, 2015. The majority of the other service offerings such as audio-visual and security, cabling, and data center work increased due to the overall volume of projects completed or in progress during the current year. Increases in these areas more than offset a decrease in high-tech manufacturing revenue, which fell by $6.0 million for the year ended September 30, 2015 compared to the year ended September 30, 2014.

Gross Profit. Gross profit during the year ended September 30, 2015 increased $4.7 million, or 22.1%, as compared to the year ended September 30, 2014. This increase was primarily driven by the overall increase in revenues noted above. Gross profit as a percentage of revenue remained unchanged from the prior year at 18.2% for the year ended September 30, 2015. During 2015, we had an increase in wireless access and VoIP projects, which generated higher margins than our other service offerings during the year ended September 30, 2014. The gross margin increase related to the wireless access was largely offset by lower margins on certain high-tech manufacturing projects, as the scopes of work contained a larger material component than labor component when compared to similar projects in progress during the year ended September 30, 2014.

Selling, General and Administrative Expenses. Selling, general and administrative expenses increased $2.3 million, or 16.7%, during the year ended September 30, 2015 compared to the year ended September 30, 2014 as a result of higher personnel cost, including increased incentive compensation associated with higher profitability. Selling, general and administrative expenses as a percentage of revenues in the Communications segment decreased 0.5% to 11.1% of segment revenue during the year ended September 30, 2015 compared to the year ended September 30, 2014 as we benefited from increased activity.

2014 Compared to 2013

Revenue. Revenues decreased by $10.3 million during the year ended September 30, 2014, an 8.1% decrease compared to the year ended September 30, 2013. The decrease is primarily the result of the completion of certain high-tech manufacturing projects performed in 2013, which did not recur in 2014. Revenues from high-tech manufacturing projects were $7.5 million during the year ended September 30, 2014, compared to $30.6 million during the year ended September 30, 2013. However, revenues attributable to data centers increased to $43.8 million for the year ended September 30, 2014 compared to $38.7 million for the year ended September 30, 2013. Data center revenue increased due to an expansion of our customer base in this market; partly offset by the decision of a large customer to procure its own materials to be used in our work, rather than sourcing those materials through us. Additionally, increased revenues from audio-visual and security work, as well as large distribution center projects, helped offset the decline in high-tech manufacturing revenue.

Gross Profit. Gross profit during the year ended September 30, 2014 decreased $2.6 million, or 11.0%, as compared to the year ended September 30, 2013. Gross profit as a percentage of revenue decreased 0.6% to 18.2% for the year ended September 30, 2014, due primarily to the relatively high margins on certain high-tech manufacturing projects which were ongoing in the year ended September 30, 2013, but did not recur in 2014.

Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased $0.1 million, or 1.0%, during the year ended September 30, 2014 compared to the year ended September 30, 2013. Selling, general and administrative expenses as a percentage of revenues in the Communications segment increased 0.8% to 11.6% of segment revenue during the year ended September 30, 2014 compared to the year ended September 30, 2013. Although costs were reduced, cost as a percentage of revenue still increased, as revenue declined, but certain of our costs were not reduced in light of an anticipated increase in activity for 2015. Additionally, we incurred $0.5 million of costs in connection with establishing new branches in Northern California and Texas in the year ended September 30, 2014.

Residential

2015 Compared to 2014

Table of Contents

Revenue. Revenues increased $23.8 million during the year ended September 30, 2015, an increase of 13.0% as compared to the year ended September 30, 2014. Single-family construction revenues increased by $15.9 million, primarily from growth in Texas, where the economy has experienced continued growth and population expansion. We continue to monitor how demand in this region may be affected by a slowdown in the oil and gas sector; we believe that sustained low levels of oil prices could result in a tapering of regional growth and lower revenues in this segment of our business. Revenue for multi-family construction increased by $3.3 million for the year ended September 30, 2015 as compared with the same period in 2014, primarily as a result of increased demand, particularly on the East Coast and in Texas. Cable and service activity, as well as revenue from solar installations, also increased year over year.

Gross Profit. During the year ended September 30, 2015, our Residential segment experienced an $8.0 million, or 23.8%, increase in gross profit as compared to the year ended September 30, 2014. Gross profit increased due to higher volume of work across all service lines. Gross margin percentage increased within single-family, as demand for single-family housing has increased combined with improved efficiency and favorable commodity prices. However, the increase in gross margin as a percentage of revenue for our single-family business was partly offset by lower margins recognized on service and cable work during the year ended September 30, 2015 due to expansion and training costs.

Selling, General and Administrative Expenses. Our Residential segment experienced a $3.9 million, or 14.1%, increase in selling, general and administrative expenses during the year ended September 30, 2015 compared to the year ended September 30, 2014. Selling, general and administrative expenses as a percentage of revenues in the Residential segment increased 0.2% to 15.5% of segment revenue during the year ended September 30, 2015. The primary driver of the increase was the cost of incentive compensation for our operations managers, which is based on a profit-sharing model, combined with higher bonus and commission expense in connection with increased levels of activity and higher profitability.

2014 Compared to 2013

Revenue. Revenues increased $19.9 million during the year ended September 30, 2014, an increase of 12.2% as compared to the year ended September 30, 2013. Single-family construction revenues increased by $16.3 million, primarily in Texas, where the economy has experienced continued growth and population expansion. Revenues for our multi-family construction increased by $2.9 million during the year ended September 30, 2014, as overall market conditions have continued to improve. Multi-family construction projects were primarily driven by increased demand for rental housing, student housing, and senior living facilities throughout the regions in which we operate. Revenue was impacted to a lesser degree by decreases in solar installations and increases in cable and service activity.

Gross Profit. During the year ended September 30, 2014, our Residential segment experienced a $6.6 million, or 24.3%, increase in gross profit as compared to the year ended September 30, 2013. Gross profit increased due to higher volume of both single-family and multi-family projects, offset by lower volume and reduced gross margin percentage in solar projects. Total Residential gross margin increased to 18.5% for the year ended September 30, 2014, compared with 16.7% for 2013. Gross margin percentage increased by 2.9%, within single-family, and 2.2% within multi-family, offset to a lesser degree by a reduction in gross margin on cable and services activity. As demand has increased within the single-family business and copper prices have become more stable, profitability has increased.

Selling, General and Administrative Expenses. Our Residential segment experienced a $2.5 million, or 9.8%, increase in selling, general and administrative expenses during the year ended September 30, 2014 compared to

32

Table of Contents

the year ended September 30, 2013. However, selling, general and administrative expenses as a percentage of revenues in the Residential segment decreased 0.3% to 15.3% of segment revenue during the year ended September 30, 2014. The primary driver of the increase was the cost of incentive compensation for our operations managers, which grew from $6.0 million for the year ended September 30, 2013 to $10.0 million for the year ended September 30, 2014. We believe this incentive compensation structure, which is based on a profit-sharing model, is typical in the industry. While incentive and compensation cost increased as a result of increased activity and profitability, these increases were partly offset by a reduction in legal fees and bad debt expense for the year ended September 30, 2014 compared to the year ended September 30, 2013.

Commercial & Industrial

2015 Compared to 2014

Revenue. Revenues increased $12.6 million during the year ended September 30, 2015, an increase of 7.6% compared to the year ended September 30, 2014. The market for this segment’s services remains highly competitive and, as such, we continue to maintain a disciplined bid strategy. However, a continued focus on our sales strategy combined with improved market conditions in certain regions where we operate led to the year over year revenue increase.

Gross Profit. Gross profit during the year ended September 30, 2015 increased by $3.4 million, or 18.6%, as compared to the year ended September 30, 2014. The increase in gross profit in the year ended September 30, 2015 as compared to 2014 was due to an overall increase in the size of projects in progress, specific to the education, power distribution, and industrial markets. Commercial & Industrial’s gross margin percentage increased 1.1% to 12.0% during the year ended September 30, 2015. The improvement in margin percentage was primarily attributable to improved productivity, as well as a more selective bidding strategy which we believe reduced our exposure to riskier projects that have historically resulted in reduced earnings. Project bid margins have continued to improve in 2015; however, the market remains competitive, and we expect continued pressure on our ability to increase project bid margins in most of the markets we serve.

Selling, General and Administrative Expenses. Selling, general and administrative expenses during the year ended September 30, 2015 increased by $0.5 million, or 3.8%, compared to the year ended September 30, 2014. Selling, general and administrative expense as a percentage of revenues in the Commercial & Industrial segment decreased by 0.3% during the year ended September 30, 2015, as we benefited from increased activity.

2014 Compared to 2013

Revenue. Revenues decreased $37.2 million during the year ended September 30, 2014, a decrease of 18.3% compared to the year ended September 30, 2013. Our Commercial & Industrial segment is impacted not only by construction industry trends, but also specific industry and local economic trends. Impacts from these trends on

33

Table of Contents

our revenues may be delayed due to the long lead time of our projects. During the year ended September 30, 2014, our revenue decrease was the result of large commercial projects for which we recognized substantial revenue in the year ended September 30, 2013, but are now complete or nearing completion.

Gross Profit. Gross profit during the year ended September 30, 2014 increased by $2.6 million, or 17.0%, as compared to the year ended September 30, 2013. Commercial & Industrial’s gross margin percentage increased 3.3% to 10.9% during the year ended September 30, 2014. The increase in margin was primarily the result of improved productivity, as well as a more selective bidding strategy. In particular, we recognized improved margins in the year ended September 30, 2014 as compared to 2013 on our ongoing major project related to the construction of an infectious disease facility which has been underway since 2009. However, gross margin on this project is still below average for our commercial projects in both 2013 and 2014. Project bid margins have continued to improve in 2014; however, the market remains competitive, and we expect continued pressure on our ability to increase project bid margins in most of the markets we serve.

Selling, General and Administrative Expenses. Selling, general and administrative expenses during the year ended September 30, 2014 increased by $0.1 million, or 0.8%, compared to the year ended September 30, 2013. Selling, general and administrative expense as a percentage of revenues in the Commercial & Industrial segment increased by 1.6% during the year ended September 30, 2014, reflective of higher incentive compensation costs in connection with increased profitability.

Infrastructure Solutions

2015 Compared to 2014

Revenue. Revenues in our Infrastructure Solutions segment decreased by $0.7 million during the year ended September 30, 2015, a decrease of 1.5% compared to the year ended September 30, 2014. The decrease in revenue was driven primarily by a decrease in demand for power assemblies by certain of our large rail customers. This decrease was partially offset by improved demand for electric motor repair services and the expansion of our customer base. Revenue for the year ended September 30, 2015 includes $2.9 million from Southern Industrial Sales and Services, Inc. (“Southern Rewinding”), a Columbus, Georgia-based motor repair and related field services company, which we acquired in May, 2015. We believe the reduction in demand for power assemblies from our current large rail customers will continue for the foreseeable future, as they shift the majority of their ongoing maintenance and repair work to a single preferred vendor.

Gross Profit. Our Infrastructure Solutions segment’s gross profit during the year ended September 30, 2015 increased by $0.7 million, or 6.8%, as compared to the year ended September 30, 2014. Gross profit increased due to higher volume of electric motor repair services combined with the addition of Southern Rewinding, which contributed $0.9 million of gross margin for the year ended September 30, 2015. Gross profit as a percentage of revenue increased from 20.9% for the year ended September 30, 2014 to 22.7% for the year ended September 30, 2015. Although revenues were down, we were able to improve our margins through a focus on workflow and process improvement, as well as cost management. Further, the favorable service and project mix at Southern Rewinding contributed to the higher margin percentage year over year. Although margins have continued to improve year over year, the markets in which we operate remain competitive due to the current economic conditions of some of the larger industries we serve, particularly the steel and rail industries. As such, we expect continued pressure on our ability to increase margins.

Table of Contents

Selling, General and Administrative Expenses. Our Infrastructure Solutions segment’s selling, general and administrative expenses during the year ended September 30, 2015 increased by $0.2 million compared to the year ended September 30, 2014. Selling, general and administrative expense as a percentage of revenue increased from 19.7% for the year ended September 30, 2014 to 20.3% for the year ended September 30, 2015. The increases were a result of certain one-time legal expenses and costs associated with the acquisition of Southern Rewinding, combined with the addition of selling, general and administrative expenses associated with Southern Rewinding’s operations. These increases were partially offset by cost reductions made at our locations that service our large rail and steel industry customers, due to the decrease in demand for our services during the year ended September 30, 2015.

2014 Compared to 2013

Our Infrastructure Solutions business was created on September 13, 2013 with the acquisition of MISCOR Group, Ltd. Therefore, amounts shown above include the results of operations beginning September 13, 2013 only. Revenues for our Infrastructure Solutions segment were $47.6 million for the year ended September 30, 2014, and include $34.4 million from industrial services and $13.2 million from engine components services. Our gross profit from industrial services was $7.2 million at a 20.2% margin, reflecting both revenue growth and an improvement in gross margins subsequent to our acquisition. This gross profit included an impact of $0.5 million of additional costs associated with the sale of inventory that was written up to fair value in purchase accounting upon the acquisition of the business in 2013. The business climate for engine components services has been more challenging during the second half of the year ended September 30, 2014, as we have experienced a decrease in demand for our engine repair services from certain large customers. However, demand has begun to increase subsequent to September 30, 2014. The engine components service line reported gross profit of $2.8 million at a margin of 21.3% for the year ended September 30, 2014. The Infrastructure Solutions segment reported $9.3 million of general and administrative expense for the year ended September 30, 2014.

Interest and Other Expense, net

Interest Expense

During the year ended September 30, 2015, we incurred interest expense of $1.1 million primarily comprised of interest expense from our term loan facility with Wells Fargo, an average letter of credit balance of $6.9 million under the 2012 Credit Facility and an average unused line of credit balance of $45.5 million. This compares to interest expense of $1.6 million for the year ended September 30, 2014, on a debt balance primarily comprised of our term loan facility with Wells Fargo, an average letter of credit balance of $6.8 million under the 2012 Credit Facility and an average unused line of credit balance of $23.8 million.

35

Table of Contents

For the year ended September 30, 2013, we incurred interest expense of $1.8 million on a debt balance primarily comprised of the Tontine Term Loan (as defined herein), financing agreements related to our commercial insurance policy premiums, an average letter of credit balance of $7.4 million under our 2006 revolving credit facility with Bank of America, N.A., and an average unused line of credit balance of $22.6 million.

PROVISION FOR INCOME TAXES

Our provision for income taxes was $0.7 million for the years ended September 30, 2015 and 2014. Tax expense increased by $0.1 million related to the federal income tax provision, $0.5 million related to the state income tax provision, and $0.1 million related to uncertain tax benefits. However, these increases were offset by a $0.7 million benefit from a reduction in our valuation allowance as a result of deferred tax liabilities added in connection with the acquisition of Southern Rewinding.

Our provision for income taxes increased from $0.3 million for the year ended September 30, 2013 to $0.7 million for the year ended September 30, 2014. The increase includes a $0.3 million increase related to the federal income tax provision and a $0.1 million increase related to the state income tax provision. We provided a valuation allowance for the federal income tax benefit resulting from the loss from operations for the year ended September 30, 2013. As a result, we did not recognize any net benefit for federal income taxes for the year ended September 30, 2013.

WORKING CAPITAL

During the year ended September 30, 2015, working capital increased by $8.9 million from September 30, 2014, reflecting a $21.1 million increase in current assets and an $12.2 million increase in current liabilities during the period.

During the year ended September 30, 2015, our current assets increased by $21.1 million, or 12.6%, to $189.0 million, as compared to $168.0 million as of September 30, 2014. The increase in current assets is driven by current trade accounts receivables, net, which increased by $15.5 million at September 30, 2015, as compared to September 30, 2014. The increase in receivables was most notable in our Communications segment, which reported significantly higher revenues year over year. Days sales outstanding (“DSOs”) increased to 56 as of September 30, 2015 from 54 as of September 30, 2014. While the rate of collections may vary, our secured position, resulting from our ability to secure liens against our customers’ overdue receivables, reasonably assures that collection will occur eventually to the extent that our security retains value. Costs and estimated earnings in excess of billings on uncompleted contracts increased by $3.5 million at September 30, 2015 as compared to September 30, 2014, primarily as a result of increased activity at our Communications segment.

During the year ended September 30, 2015, our total current liabilities increased by $12.2 million to $108.1 million, compared to $95.9 million as of September 30, 2014. The increase was driven primarily by an increase in accounts payable and accrued expenses, which increased by $8.9 million at September 30, 2015 as compared with September 30, 2014. The increase is driven by increased activity at our Communications segment.

Surety

Many customers, particularly in connection with new construction, require us to post performance and payment bonds issued by a surety. These 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

36

Table of Contents

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 could be a claim for damages by the customer for the costs of replacing us with another contractor.

As of September 30, 2015, the estimated cost to complete our bonded projects was approximately $85.9 million. We believe the bonding capacity currently provided by our sureties is adequate for our current operations and will be adequate for our operations for the foreseeable future.

LIQUIDITY AND CAPITAL RESOURCES

As of September 30, 2015, we had cash and cash equivalents of $49.4 million and $22.8 million of availability under our 2012 Credit Facility. We anticipate that the combination of cash on hand, cash flows and available capacity under our 2012 Credit Facility will provide sufficient cash to enable us to meet our working capital needs, debt service requirements and capital expenditures for property and equipment through the next twelve months. Our ability to generate cash flow is dependent on many factors, including demand for our services, the availability of projects at margins acceptable to us, the ultimate collectability of our receivables, and our ability to borrow on our 2012 Credit Facility or raise funds in the capital markets, if needed.

We continue to monitor the financial markets and general national and global economic conditions. To date, we have experienced no loss or lack of access to our invested cash or cash equivalents; however, we can provide no assurances that access to our invested cash and cash equivalents will not be impacted in the future by adverse conditions in the financial markets.

The 2012 Revolving Credit Facility

On August 9, 2012, we entered into a Credit and Security Agreement (the “Credit Agreement”), for a credit facility (as amended, the “2012 Credit Facility”) with Wells Fargo Bank, National Association (“Wells Fargo”). We have subsequently entered into four amendments to the 2012 Credit Facility and entered into an Amended and Restated Credit and Security Agreement (the “Amended Credit Agreement”) as of September 24, 2014, which increased the maximum revolver amount under the 2012 Credit Facility from $30 million to $60 million, and extended the maturity date by one year to August 9, 2018. In addition, under the Amended Credit Agreement, the Company eliminated its term loan facility so that borrowings that would previously have been made under the term loan facility, including borrowings for acquisitions, are now made under the revolving credit facility with terms more favorable than the term loan facility, including a lower interest rate, as described below.

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. At September 30, 2015, we were subject to the financial covenant under the 2012 Credit Facility requiring, at any time that our Liquidity (the aggregate amount of unrestricted cash and cash equivalents on hand plus Excess Availability, as defined in the Amended Credit Agreement) is less than $20 million or our Excess Availability is less than $5 million, that we maintain a Fixed Charge Coverage Ratio of not less than 1.0:1.0. At September 30, 2015, our Liquidity was $72.2 million and our Excess Availability was $22.8 million, and as such, we were not required to maintain a Fixed Charge Coverage Ratio of 1.0:1.0 as of such date. Nonetheless, at September 30, 2015, our Fixed Charge Coverage Ratio was 4.0:1.0. Compliance with our Fixed Charge Coverage Ratio, while not

37

required at September 30, 2015, provides us with the ability to use cash on hand or to draw on our 2012 Credit Facility such that we can fall below the Excess Availability and Liquidity minimum thresholds described above without violating our financial covenant.

Our Fixed Charge Coverage Ratio is calculated as (i) our trailing twelve month EBITDA (as defined in the Amended Credit Agreement), less non-financed capital expenditures (other than capital expenditures financed by means of an advance under the 2012 Credit Facility) cash taxes and certain pass-through tax liabilities, divided by (ii) the sum of our cash interest and principal debt payments (other than repayment of principal on advances under the 2012 Credit Facility) and all Restricted Junior Payments (as defined in the Amended Credit Agreement) (other than pass-through tax liabilities) and other cash distributions. As defined in the Amended Credit Agreement, EBITDA is calculated as consolidated net income (or loss), less extraordinary gains, interest income, non-operating income and income tax benefits and decreases in any change in LIFO reserves, plus stock compensation expense, non-cash extraordinary losses, interest expense, income taxes, depreciation and amortization and increases in any change in LIFO reserves.

If in the future our Liquidity or Excess Availability fall below $20 million or $5 million, respectively, and at that time our Fixed Charge Coverage Ratio is less than 1.0:1.0, or if we otherwise fail to perform or otherwise comply with certain of our covenants or other agreements under our 2012 Credit Facility, it would result in an event of default under our 2012 Credit Facility, which could result in some or all of our indebtedness becoming immediately due and payable.

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 Amended 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 thousand to $2 thousand, 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 Amended Credit Agreement.

At September 30, 2015, we had $22.8 million under the 2012 Credit Facility that was available to us without triggering or violating our financial covenant, $6.9 million in outstanding letters of credit with Wells Fargo and outstanding borrowings of $10.2 million

The Tontine Term Loan

On December 12, 2007, we entered into the Tontine Term Loan, a $25 million senior subordinated loan agreement, with Tontine, which the Company terminated and prepaid in full through a final payment of $10 million in February, 2013.

Rights Offering

On August 7, 2014, we completed a $20 million rights offering (the “Rights Offering”). In the Rights Offering, we distributed, at no charge, to the holders of shares of our common stock one non-transferable subscription right for each share of common stock owned as of the record date. Each right entitled the holder thereof to purchase from the Company 0.214578135 shares of common stock at a subscription price of $5.20 per share (the “Basic Subscription Rights”), which represented a discount to the market price of our common stock at the closing of the offering. In addition, holders who purchased all of the shares of common stock available to them pursuant to their Basic Subscription Rights were entitled to subscribe, at the same subscription price of $5.20 per share, for a portion of any shares of common stock that other holders did not purchase through the exercise of their Basic Subscription Rights, subject to certain limitations (the “Over-Subscription Privilege”). The Rights Offering was fully subscribed, after giving effect to the exercise of Over-Subscription Privileges, and we received net proceeds of approximately $19.6 million, after deducting estimated offering expenses, for the issuance of 3,846,150 shares of common stock in the Rights Offering.

Immediately after giving effect to the Rights Offering, we had 21,768,642 shares of common stock issued and outstanding. Tontine beneficially owned approximately 60% of the shares of common stock outstanding immediately prior to launch of the Rights Offering, and immediately after giving effect to the Rights Offering, Tontine beneficially owned approximately 61% of the Company’s outstanding shares.

Investments

From time to time, the Company may invest in non-controlling positions in the debt or equity securities of other businesses. In October 2014, our Board of Directors approved an investment policy that permits the Company to invest our cash in liquid and marketable securities that include equities and fixed income securities, subject to Board approval of any such investment over $0.5 million. Equity securities may include unrestricted, publicly traded stock that is listed on a major exchange or a national, over-the-counter market and that is appropriate for our portfolio objectives, asset class, and/or investment style, and fixed income securities are required to have an investment grade credit quality at the time of purchase.

Operating Activities

Our cash flow from operations is not only influenced by cyclicality, demand for our services, operating margins and the type of services we provide, but can also be influenced by working capital needs such as the timing of our receivable collections. Working capital needs are generally lower during our fiscal first and second quarters due to the seasonality that we experience in many regions of the country.

Operating activities provided net cash of $11.5 million during the year ended September 30, 2015, as compared to $12.6 million of net cash provided in the year ended September 30, 2014. Although we reported higher net income in the year ended September 30, 2015 as compared to the year ended September 30, 2014, we ended fiscal 2015 with higher levels of working capital in connection with increased levels of activity, as well as working capital requirements at our Southern Rewinding acquisition, where we used $1.1 million to pay down accounts payable and accrued liabilities immediately upon closing the acquisition.

Operating activities provided net cash of $12.6 million during the year ended September 30, 2014, as compared to $2.0 million of net cash provided in the year ended September 30, 2013. In addition to higher net income in the year ended September 30, 2014 as compared to the year ended September 30, 2013, we ended fiscal 2014 with lower levels of working capital in connection with decreased inventory and other current asset balances.

Investing Activities

In the year ended September 30, 2015, net cash used in investing activities was $5.9 million as compared to $2.0 million of net cash used by investing activities in the year ended September 30, 2014. Investing activities for the year ended September 30, 2015 include $3.1 million for the purchase of Southern Rewinding, as well as

$2.8 million of capital expenditures. Investing activities of $2.0 million in the year ended September 30, 2014 relate to capital expenditures. Investing activities for the year ended September 30, 2013 were comprised of $5.2 million used in conjunction with the acquisition of MISCOR Group, Ltd. and the acquisition of certain assets from the Acro Group, and $0.4 million used for capital expenditures, partly offset by $0.8 million in proceeds from the sale of a building.

Financing Activities

Financing activities used net cash of $3.6 million in the year ended September 30, 2015 compared to $16.0 million provided in the year ended September 30, 2014. For the year ended September 30, 2015, we used $3.6 million for repurchases of the Company’s common stock under the authorized stock repurchase program. Common stock of $3.5 million was repurchased from an unrelated, third-party investor and in open market transactions, pursuant to the stock repurchase program, and we used an additional $0.1 million for the repurchase of common stock to satisfy employee payroll tax withholding obligations. For the year ended September 30, 2014, we raised $19.6 million through our Rights Offering. This was partly offset by $3.5 million used for repayments on our 2012 Credit Facility and $0.2 million used for the repurchase of common stock to satisfy employee payroll tax withholding obligations. For the year ended September 30, 2013, we entered into our term loan facility with Wells Fargo, repaid the Tontine Term Loan, and repaid $5.6 million in debt acquired immediately subsequent to the MISCOR acquisition. Financing activities in the year ended September 30, 2013 also included the release of $7.1 million in restricted cash, as the requirement to cash collateralize borrowings on our 2012 Credit Facility was removed.

CONTROLLING SHAREHOLDER

On October 15, 2015, Tontine filed an amended Schedule 13D indicating its ownership level of 62.2% of the Company’s outstanding common stock. As a result, Tontine can control most of our affairs, including most actions requiring the approval of shareholders, such as the approval of any potential merger or sale of all or substantially all assets, segments, or the Company itself.

On March 13, 2013, the Company announced the entry into the Agreement and Plan of Merger with MISCOR, which was amended by the First Amendment to Agreement and Plan of Merger, dated as of July 10, 2013 (as amended, the “Merger Agreement”). As of July 24, 2013, Tontine beneficially owned 49.9% of the issued and outstanding shares of MISCOR common stock. Given Tontine’s significant holdings in both the Company and MISCOR, only the disinterested members of the IES Board of Directors voted on, and unanimously approved, the Merger Agreement. In addition, MISCOR established a special committee of independent directors that voted on and approved the Merger Agreement and recommended approval of the Merger Agreement by the MISCOR full board of directors. After receiving approval from the special committee, the disinterested members of the MISCOR board of directors unanimously approved the Merger Agreement. The merger was finalized on September 13, 2013. In connection with the merger, Tontine elected to receive stock consideration in exchange for 100% of its shares of MISCOR common stock tendered pursuant to the merger, such that, according to its amended Schedule 13D filed on September 13, 2013, its ownership of IES common stock increased from approximately 56.7% immediately prior to the merger to approximately 58.0% immediately following the merger.

We are a party to a sublease agreement with Tontine Associates, LLC, an affiliate of our controlling shareholder, for corporate office space in Greenwich, Connecticut. The sublease extends through March, 2016, with terms at market rates, and payments by the Company are at a rate consistent with that paid by Tontine Associates, LLC to its landlord.

David B. Gendell has served as a member of the Board of Directors since February 2012 and as the Company’s non-executive Chairman of the Board since January, 2015. Mr. Gendell, who is the brother of Jeffrey Gendell, the founder and managing member of Tontine, is also an employee of Tontine.

OFF-BALANCE SHEET ARRANGEMENTS AND CONTRACTUAL OBLIGATIONS

As is common in our industry, we have entered into certain off-balance sheet arrangements that expose us to increased risk. Our significant off-balance sheet transactions include commitments associated with non-cancelable operating leases, letter of credit obligations, firm commitments for materials and surety guarantees.

We enter into non-cancelable operating leases for many of our vehicle and equipment needs. These leases allow us to retain our cash when we do not own the vehicles or equipment, and we pay a monthly lease rental fee. At the end of the lease, we have no further obligation to the lessor. We may cancel or terminate a lease before the end of its term. Typically, we would be liable to the lessor for various lease cancellation or termination costs and the difference between the fair market value of the leased asset and the implied book value of the leased asset as calculated in accordance with the lease agreement.

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 September 30, 2015, $0.6 million of our outstanding letters of credit were to collateralize our customers and vendors.

Some of the underwriters of our casualty insurance program require us to post letters of credit as collateral, as 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 September 30, 2015, $6.3 million of our outstanding letters of credit were to collateralize our insurance programs.

From time to time, we may enter into firm purchase commitments for materials such as copper wire and aluminum wire, among others, 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 specified intervals at a fixed price over the term. As of September 30, 2015, we did not have any open purchase commitments.

Many of our customers require us to post performance and payment bonds issued by a surety. Those bonds guarantee the customer that we will perform under the terms of a contract and that we will pay subcontractors and vendors. In the event that we fail to perform under a contract or pay subcontractors and vendors, the customer may demand the surety to pay or perform under our bond. Our relationship with our sureties is such that we will indemnify the sureties for any expenses they incur in connection with any of the bonds they issue on our behalf. To date, we have not incurred any costs to indemnify our sureties for expenses they incurred on our behalf.

As of September 30, 2015, our future contractual obligations due by September 30 of each of the following fiscal years include (in thousands) (1):

CRITICAL ACCOUNTING POLICIES

The discussion and analysis of our financial condition and results of operations are based on our Consolidated Financial Statements, which have been prepared in accordance with Generally Accepted Accounting Principles in the U.S. (“GAAP”). The preparation of our Consolidated Financial Statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities known to exist as of the date the Consolidated Financial Statements, and the reported amounts of revenues and expenses recognized during the periods presented. We review all significant estimates affecting our Consolidated Financial Statements on a recurring basis and record the effect of any necessary adjustments prior to their publication. Judgments and estimates are based on our beliefs and assumptions derived from information available at the time such judgments and estimates are made. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of financial statements. There can be no assurance that actual results will not differ from those estimates.

Accordingly, we have identified the accounting principles which we believe are most critical to our reported financial status by considering accounting policies that involve the most complex or subjective decisions or assessments. We identified our most critical accounting policies to be those related to revenue recognition, the assessment of goodwill and asset impairment, our allowance for doubtful accounts receivable, the recording of our insurance liabilities and estimation of the valuation allowance for deferred tax assets, and unrecognized tax benefits. These accounting policies, as well as others, are described in Note 2, “Summary of Significant Accounting Policies” in the notes to our Consolidated Financial Statements, and at relevant sections in this discussion and analysis.

Revenue Recognition. We enter into contracts principally on the basis of competitive bids. We frequently negotiate the final terms and prices of those contracts with the customer. Although the terms of our contracts vary considerably, over 90% of our revenues are based on either a fixed price or unit price basis in which we agree to do the work for a fixed amount for the entire project (fixed price) or for units of work performed (unit price). Approximately 5% of our revenues are earned from contracts where we are paid on a time and materials basis, and from time to time, we may enter into contracts on a cost plus basis. Our most significant cost drivers are the cost of labor, the cost of materials and the cost of casualty and health insurance. These costs may vary from the costs we originally estimated. Variations from estimated contract costs along with other risks inherent in performing fixed price and unit price contracts may result in actual revenue and gross profits or interim projected revenue and gross profits for a project differing from those we originally estimated and could result in losses on projects. Depending on the size of a particular project, variations from estimated project costs could have a significant impact on our operating results for any fiscal quarter or year.

We complete most of our projects within one year. We frequently provide service and maintenance work under open-ended, unit price master service agreements which are renewable annually. We recognize revenue on service, time and material work when services are performed. Work performed under a construction contract generally provides that the customers accept completion of progress to date and compensate us for services rendered, measured in terms of units installed, hours expended or some other measure of progress. Revenues from construction contracts are recognized on the percentage-of-completion method. Revenues recognized on a percentage-of-completion basis, all of which are fixed price arrangements, comprised approximately 67% of our total revenue for the year ended December 31, 2015. The percentage-of-completion method for construction contracts is measured principally by the percentage of costs incurred and accrued to date for each contract to the estimated total costs for each contract at completion. We generally consider contracts substantially complete

42

upon departure from the work site and acceptance by the customer. Contract costs include all direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation costs. Changes in job performance, job conditions, estimated contract costs, profitability and final contract settlements may result in revisions to costs and income, and the effects of such revisions are recognized in the period in which the revisions are determined. Provisions for total estimated losses on uncompleted contracts are made in the period in which such losses are determined.

The current asset “Costs and estimated earnings in excess of billings on uncompleted contracts” represents revenues recognized in excess of amounts billed that management believes will be billed and collected within the next twelve months. The current liability “Billings in excess of costs and estimated earnings on uncompleted contracts” represents billings in excess of revenues recognized. Costs and estimated earnings in excess of billings on uncompleted contracts are amounts considered recoverable from customers based on different measures of performance, including achievement of specific milestones, completion of specified units or completion of the contract. Also included in this asset, from time to time, are claims and unapproved change orders, which include amounts that we are in the process of collecting from our customers or agencies for changes in contract specifications or design, contract change orders in dispute or unapproved as to scope and price, or other related causes of unanticipated additional contract costs. Claims and unapproved change orders are recorded at estimated realizable value when collection is probable and can be reasonably estimated. We do not recognize profits on construction costs incurred in connection with claims. Claims made by us involve negotiation and, in certain cases, litigation. Such litigation costs are expensed as incurred.

Valuation of Intangibles and Long-Lived Assets. We evaluate goodwill for potential impairment at least annually at year end, however, if impairment indicators exist, we will evaluate as needed. In evaluating goodwill for impairment, we have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is greater than its carrying value. If we determine that it is more likely than not that the carrying value of a reporting unit is greater than its fair value, then we perform an impairment test by calculating the fair value of the reporting unit and comparing this calculated fair value with the carrying value of the reporting unit. We estimate the fair value of the reporting unit based on the market approach and income approach. Included in this evaluation are certain assumptions and estimates to determine the fair values of reporting units such as estimates of future cash flows and discount rates, as well as assumptions and estimates related to the valuation of other identified intangible assets. Changes in these assumptions and estimates or significant changes to the market value of our common stock could materially impact our results of operations or financial position. We did not record goodwill impairment during the years ended September 30, 2015, 2014 or 2013.

For our Infrastructure Solutions reporting unit, even a small decline in estimated fair value as of the September 30, 2015 testing date could trigger an impairment of goodwill. The fair value calculation for Infrastructure Solutions is highly sensitive to changes in projections for revenue growth rates and gross margins. Our current expectation is for Infrastructure Solutions to average high single digit revenue growth for 2016, with average low single digit rates in the following years, excluding the impact of our recent acquisition of Calumet. Our ability to achieve the projected revenue growth may be affected by, among other factors, (a) pricing and product competition; (b) the timing and extent of recovery of the steel and rail markets; and (c) our ability to diversify our customer base.

We believe that if Infrastructure Solutions is unable to achieve the projected financial performance, either in the near term or long term, impairment is likely to result. Total recorded goodwill for the Infrastructure Solutions reporting unit as of September 30, 2015 is $8.6 million.

Each reporting period, we assess impairment indicators related to long-lived assets and intangible assets. If we determine impairment indicators exist, we conduct an evaluation to determine whether any impairment has occurred. This evaluation includes certain assumptions and estimates to determine fair value of asset groups, including estimates about future cash flows and discount rates, among others. Changes in these assumptions and estimates could materially impact our results of operations or financial projections. We recorded long-lived or intangible asset impairment during the year ended September 30, 2013 of $0.2 million, which was primarily

43

Table of Contents

attributable to real estate we sold at September 30, 2013. The impairment charges were recorded to reduce the carrying value of the property to its current expected fair value. No impairment charges were recorded in the year ended September 30, 2015 or 2014.

Current and Non-Current Accounts Receivable and Provision for Doubtful Accounts. We provide an allowance for doubtful accounts for unknown collection issues, in addition to reserves for specific accounts receivable where collection is considered doubtful. Inherent in the assessment of the allowance for doubtful accounts are certain judgments and estimates including, among others, our customers’ access to capital, our customers’ willingness to pay, general economic conditions, and the ongoing relationships with our customers. In addition to these factors, the method of accounting for construction contracts requires the review and analysis of not only the net receivables, but also the amount of billings in excess of costs and costs in excess of billings. The analysis management utilizes to assess collectability of our receivables includes detailed review of older balances, analysis of days sales outstanding where we include in the calculation, in addition to accounts receivable balances net of any allowance for doubtful accounts, the level of costs in excess of billings netted against billings in excess of costs, and the ratio of accounts receivable, net of any allowance for doubtful accounts plus the level of costs in excess of billings, to revenues. These analyses provide an indication of those amounts billed ahead of or behind the recognition of revenue on our construction contracts and are important to consider in understanding the operational cash flows related to our revenue cycle.

Risk-Management. We are insured for workers’ compensation, automobile liability, general liability, construction defects, pollution, employment practices and employee-related health care claims, subject to deductibles. Our general liability program provides coverage for bodily injury and property damage. Losses up to the deductible amounts are accrued based upon our estimates of the liability for claims incurred and an estimate of claims incurred but not reported. The accruals are derived from actuarial studies, known facts, historical trends and industry averages utilizing the assistance of an actuary to determine the best estimate of the ultimate expected loss. We believe such accruals to be adequate; however, insurance liabilities are difficult to assess and estimate due to unknown factors, including the severity of an injury, the determination of our liability in proportion to other parties, the number of incidents incurred but not reported and the effectiveness of our safety program. Therefore, if actual experience differs from the assumptions used in the actuarial valuation, adjustments to the reserve may be required and would be recorded in the period that the experience becomes known.

Valuation Allowance for Deferred Tax Assets. We regularly evaluate valuation allowances established for deferred tax assets for which future realization is uncertain. We perform this evaluation quarterly. The estimation of required valuation allowances includes estimates of future taxable income. In assessing the realizability of deferred tax assets at September 30, 2015, we considered that it was more likely than not that some or all of the deferred tax assets would not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. We consider the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment.

Over the ten-year period from 2004 through 2013, the Company reported net losses each year, finally returning to profitability in the year ended September 30, 2014. Although we have recently returned to profitability, GAAP guidelines place considerably more weight on historical results and less weight on future projections and as such the cumulative pretax losses provide sufficient negative evidence to support the appropriateness of a full valuation allowance. We will release this valuation allowance when management determines that it is more likely than not that our deferred tax assets will be realized. We may be required to release all or a portion of this valuation allowance in the next 12 months, although the exact timing and the portion of the valuation allowance released are subject to the level of profitability that we are able to achieve for the year and our visibility into future period results.

We expect that the release of the valuation allowance will be recorded as an income tax benefit at the time of release, significantly increasing our reported net income, thus, significantly reducing our effective tax rate and likely resulting in a negative effective tax rate. However, we expect our effective tax rate to increase in

44

Table of Contents

subsequent periods following any significant release of the valuation allowance. Our net income and effective tax rate will be affected negatively in periods following the release. However, any valuation allowance release will not affect the amount of cash paid for income taxes.

Income Taxes. GAAP specifies the methodology by which a company must identify, recognize, measure and disclose in its financial statements the effects of any uncertain tax return reporting positions that it has taken or expects to take. GAAP requires financial statement reporting of the expected future tax consequences of uncertain tax return reporting positions on the presumption that all relevant tax authorities possess full knowledge of those tax reporting positions, as well as all of the pertinent facts and circumstances, but it prohibits discounting of any of the related tax effects for the time value of money.

The evaluation of a tax position is a two-step process. The first step is the recognition process to determine if it is more likely than not that a tax position will be sustained upon examination by the appropriate taxing authority, based on the technical merits of the position. The second step is a measurement process whereby a tax position that meets the more likely than not recognition threshold is calculated to determine the amount of benefit/expense to recognize in the financial statements. The tax position is measured at the largest amount of benefit/expense that is more likely than not of being realized upon ultimate settlement.

We are currently not under federal audit by the Internal Revenue Service. The tax years ended September 30, 2012 and forward are subject to audit as are prior tax years, to the extent of unutilized net operating losses generated in those years.

We anticipate that approximately $6 thousand in liabilities for unrecognized tax benefits, including accrued interest, may be reversed in the next twelve months. This reversal is predominantly due to the expiration of the statutes of limitation for unrecognized tax benefits.

New Accounting Pronouncements. Recent accounting pronouncements are described in Note 2, “Summary of Significant Accounting Policies — New Accounting Pronouncements” in the notes to our Consolidated Financial Statements, and at relevant sections in this discussion and analysis.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Management is actively involved in monitoring exposure to market risk and continues to develop and utilize appropriate risk management techniques. Our exposure to significant market risks includes fluctuations in labor costs, commodity prices for copper, aluminum, steel and fuel. Commodity price risks may have an impact on our results of operations due to the fixed price nature of many of our contracts. We are also exposed to interest rate risk with respect to our outstanding debt obligations on the 2012 Credit Facility. For additional information see “Risk Factors” in Item 1A of this Form 10-K.

Commodity Risk

Our exposure to significant market risks includes fluctuations in commodity prices for copper, aluminum, steel and fuel. Commodity price risks may have an impact on our results of operations due to fixed nature of many of our contracts. Over the long-term, we expect to be able to pass along a portion of these costs to our customers, as market conditions in the construction industry will allow.

Interest Rate Risk

We are subject to interest rate risk on our floating interest rate borrowings. Floating rate debt, where the interest rate fluctuates periodically, exposes us to short-term changes in market interest rates.

All of the long-term debt outstanding under our 2012 Credit Facility is structured on floating interest rate terms. A one percentage point increase in the interest rates on our long-term debt outstanding under our 2012 Credit Facility as of September 30, 2015 would cause a $0.1 million pre-tax annual increase in interest expense.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of

Integrated Electrical Services, Inc.

We have audited the accompanying consolidated balance sheets of Integrated Electrical Services, Inc. and subsidiaries (“the Company”) as of September 30, 2015 and 2014, and the related consolidated statements of comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended September 30, 2015. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Integrated Electrical Services, Inc. and subsidiaries at September 30, 2015 and 2014, and the consolidated results of their operations and their cash flows for each of the three years in the period ended September 30, 2015, in conformity with U.S. generally accepted accounting principles.
