TABLE OF CONTENTS

# PART I

| Item 1. | Business

## General

We are a holding company of specialty electrical construction service providers that was established in 1995 through the merger of long-standing specialty contractors. Through our subsidiaries, we have served the electric utility infrastructure markets since 1891. Our operations are currently conducted through wholly-owned subsidiaries, including: The L. E. Myers Co.; Harlan Electric Company; Great Southwestern Construction, Inc.; Sturgeon Electric Company, Inc.; MYR Transmission Services, Inc.; E.S. Boulos Company; High Country Line Construction, Inc.; MYR Group Construction Canada, Ltd.; MYR Transmission Services Canada, Ltd.; and Northern Transmission Services, Ltd. We provide electrical construction services, and limited gas construction services, through a network of local offices located throughout the United States and Canada. We provide a broad range of services, which includes design, engineering, procurement, construction, upgrade, maintenance and repair services, with a particular focus on construction, maintenance and repair.

Our principal executive offices are located at 1701 Golf Road, Suite 3-1012, Rolling Meadows, Illinois 60008. The telephone number of our principal executive offices is (847) 290-1891.

## Reportable Segments

We are a leading specialty contractor serving the electrical infrastructure market in the United States. We also have operations in parts of Canada. We manage and report our operations through two industry segments: Transmission and Distribution (“T&D”) and Commercial and Industrial (“C&I”) electrical contracting services.

In the second quarter of 2015, we expanded the geographic reach of our C&I segment to the northeastern United States, while enhancing our northeastern T&D presence, with the acquisition of E.S. Boulos Company (“ESB”). In the fourth quarter of 2015 we expanded our T&D segment in the western United States with the acquisition of High Country Line Construction (“HCL”).

Transmission and Distribution segment We have operated in the T&D industry since 1891. We are one of the largest U.S. contractors servicing the T&D sector of the electric utility industry. We provide a broad range of services on electric transmission and distribution networks and substation facilities, which include design, engineering, procurement, construction, upgrade, maintenance and repair services, with a particular focus on construction, maintenance and repair, to customers in the electric utility and the renewable energy industries throughout the United States and in parts of Canada. Our T&D services include the construction and maintenance of high voltage transmission lines, substations and lower voltage underground and overhead distribution systems. We also provide storm restoration services in response to hurricane, ice or other storm-related damage.

In our T&D segment, we generally serve the electric utility industry as a prime contractor, either through traditional design-bid-build or engineering, procurement and construction (“EPC”) forms of project delivery. We have long-standing relationships with many of our T&D customers who rely on us to construct and maintain reliable electric and other utility infrastructure. We also provide many services to our customers under multi-year master service agreements (“MSAs”) and other variable-term service agreements. We generally focus on improving our profitability by selecting projects we believe will provide attractive margins, actively monitoring the costs of completing our projects, holding customers accountable for costs related to changes to contract specifications, and rewarding our employees for effectively managing costs.

Commercial and Industrial segment We have provided electrical contracting services for C&I construction in the western United States since 1912. Our C&I segment provides services such as the design, installation, maintenance and repair of commercial and industrial wiring, installation of traffic networks and the installation of bridge, roadway and tunnel lighting. Our C&I operations are primarily in the western United States where we have sufficient scale to deploy the level of resources necessary to achieve significant market share. We concentrate our efforts on projects where our technical and project management expertise are critical to successful and timely execution. Typical C&I contracts cover electrical contracting services for

1

TABLE OF CONTENTS

airports, hospitals, data centers, hotels, stadiums, convention centers, manufacturing plants, processing facilities, waste-water treatment facilities, mining facilities and transportation control and management systems.

In our C&I segment, we generally provide our electric construction and maintenance services as a subcontractor to general contractors in the C&I industry, but also contract directly with facility owners. We have a diverse customer base with many long-standing relationships.

Additional financial information related to our business segments is provided under “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in Note 14 to our Financial Statements.

## Customers

Our T&D customers include many of the leading companies in the electric utility industry. Our T&D customers include investor-owned utilities, cooperatives, private developers, government-funded utilities, independent power producers, independent transmission companies, industrial facility owners and other contractors. Our C&I customer base includes general contractors, commercial and industrial facility owners, local governments and developers. We have long-standing relationships with many of our customers, and we cultivate these relationships at all levels of our organization from senior management to project supervisors. We seek to build upon our customer relationships to secure additional projects from our current customer base. Many of our customer relationships originated decades ago and are maintained through a partnering approach, which includes project evaluation and consulting, quality performance, performance measurement and direct customer contact. At all levels of management we maintain a focus on pursuing growth opportunities with prospective customers. In addition, our management teams promote and market our services for prospective large-scale projects and national accounts. We believe that our industry experience, technical expertise, customer relationships and emphasis on safety and customer service contribute to us obtaining new contracts with both existing and new customers.

For the years ended December 31, 2015, 2014 and 2013, our top 10 customers accounted for 44.6%, 46.5%, and 57.8% of our revenues, respectively. For the years ended December 31, 2015, 2014 and 2013, no single customer accounted for more than 10.0% of annual revenues.

For the years ended December 31, 2015, 2014 and 2013, revenues derived from T&D customers accounted for 74.9%, 74.1%, and 80.0%, of our total revenues, respectively, and revenues derived from C&I customers accounted for 25.1%, 25.9% and 20.0% of our total revenues, respectively.

## Types of Service Arrangements and Bidding Process

We enter into contracts principally through a competitive bid process. Our typical construction project begins with the preparation and submission of a bid to a customer. If selected as the successful bidder, we generally enter into a contract with the customer that provides for payment upon completion of specified work or units of work as identified in the contract. Although there is considerable variation in the terms of the contracts we undertake, our contracts are primarily structured as fixed-price agreements, under which we agree to do the entire project for a fixed amount or unit-price agreements, under which we agree to do the work at a fixed price per unit of work as specified in the agreement. We also enter into time-and-equipment contracts under which we are paid for labor and equipment at negotiated hourly billing rates and for other expenses, including materials, as incurred, and time-and-materials contracts under which we are paid for labor at negotiated hourly billing rates and for other expenses, including materials, as incurred. Finally, we sometimes enter into cost-plus contracts, where we are paid for our costs plus a negotiated margin. On occasion, time-and-equipment, time-and-materials and cost-plus contracts require us to include a guaranteed not-to-exceed maximum price.

Fixed-price and unit-price contracts typically have the highest potential margins; however, they hold a greater risk in terms of profitability because cost overruns may not be recoverable. Time-and-equipment, time-and-materials and cost-plus contracts have less margin upside, but generally have a lower risk of cost overruns. Work in our T&D segment is generally completed under fixed-price, time-and-materials, time-and-equipment, unit-price and cost-plus agreements. C&I work is typically performed under fixed-price, time-and-materials, cost-plus, and unit-price agreements. Fixed-price contracts accounted for 54.2% of total

2

TABLE OF CONTENTS

revenue for the year ended December 31, 2015, including 48.4% of our total revenue for our T&D segment and 71.6% of our total revenue for our C&I segment.

Our EPC contracts are typically fixed-price. We may act as the prime contractor for an EPC project where we perform the procurement and construction functions but use a subcontractor to perform the engineering component, or we may use a subcontractor for both engineering and procurement functions. We may also act as a subcontractor on an EPC project to an engineering or construction management firm. When acting as a subcontractor for an EPC project, we typically provide construction services only, although we may also perform both the construction and procurement functions.

Our T&D segment also provides services under MSAs that cover maintenance, upgrade and extension services, as well as new construction. Work performed under MSAs is typically billed on a unit-price, time-and-materials or time-and-equipment basis. MSAs are typically one to three years in duration; however, most of our contracts, including MSAs, may be terminated by our customers on short notice, typically 30 to 90 days, even if we are not in default under the contract. Under MSAs, customers generally agree to use us for certain services in a specified geographic region. Most MSA customers have no obligation to assign specific volumes of work to us and are not required to use us exclusively, although in some cases they are subject to our right of first refusal. Many of our contracts, including MSAs, are open to public bid at expiration and generally attract numerous bidders.

A portion of the work we perform requires performance and payment bonds at the time of execution of the contract. Contracts generally include retention provisions of up to 10% which may be withheld from each progress payment as retainage until the contract work has been completed and approved.

## Materials

In many cases, our T&D customers are responsible for supplying their own materials on projects; however, under certain contracts, we may agree to provide all or a portion of the required materials. For our C&I contracts, we usually procure the necessary materials and supplies. We are not dependent on any one supplier for materials or supplies.

## Subcontracting

We are the prime contractor for the majority of our T&D projects. We may use subcontractors to perform portions of our contracts and to manage workflow, particularly for design, engineering, procurement and some foundation work. We often work with subcontractors who are sole proprietorships or small business entities. Subcontractors normally provide their own employees, vehicles, tools and insurance coverage. We are not dependent on any single subcontractor. Contracts with subcontractors often contain provisions limiting our obligation to pay the subcontractor if our client has not paid us. We hold our subcontractors responsible for their work or delays in their performance. On larger projects we may require performance and payment bonding from subcontractors, where we deem appropriate, based on the risk involved. We occasionally perform work as a subcontractor, and we may elect to do so from time-to-time on larger projects in order to manage our execution risk.

The majority of the work in our C&I segment is done as a subcontractor to a general contractor.

## Competition

Our business is highly competitive in both our T&D and C&I segments. Competition in both of our business segments is primarily based on the price of the construction services and upon the reputation for safety, quality and reliability of the contractor. The competition we encounter can vary depending upon the type and/or location of construction services.

We believe that the principal competitive factors that customers consider in our industry are:

| • | price and flexible contract terms;

| • | safety programs and safety performance;

| • | technical expertise and experience;

| • | management team experience;

3

TABLE OF CONTENTS

| • | reputation and relationships with the customer;

| • | geographic presence and breadth of service offerings;

| • | willingness to accept risk;

| • | quality of service execution;

| • | specialized equipment, tooling and centralized fleet structure;

| • | the availability of qualified and/or licensed personnel;

| • | adequate financial resources and bonding capacity;

| • | weather-damage restoration abilities and reputation; and

| • | technological capabilities.

While we believe our customers consider a number of factors when selecting a service provider, most of their work is awarded through a bid process where price is always a principal factor. See “Risk Factors-Our industry is highly competitive.”

#### T&D Competition

Our T&D segment competes with a number of companies in the local markets where we operate, ranging from small local independent companies to large national firms. The national or large regional firms that compete with us for T&D contracts include Asplundh Construction Corp., Davis H. Elliot Company, Inc., Henkels & McCoy, Inc., MasTec, Inc., MDU Resources Group, Inc., Michels Corporation, Pike Corporation, Power Line Services, Inc., Quanta Services, Inc. and Willbros Group, Inc.

There are a number of barriers to entry into the transmission services business, including the cost of equipment and tooling necessary to perform transmission work, the availability of qualified labor, the scope of typical transmission projects and the technical, managerial and supervisory skills necessary to complete the job. Larger transmission projects generally require specialized heavy duty equipment as well as strong financial resources to meet the cash flow, bonding, or letter of credit requirements of these projects. These factors sometimes reduce the number of potential competitors on these projects. The number of firms that generally compete for any one significant transmission infrastructure project varies greatly depending on a number of factors, including the size of the project, its location and the bidder qualification requirements imposed upon contractors by the customer. Some of our competitors restrict their operations to one geographic area, and others operate nationally and internationally.

Compared to the transmission markets, there are fewer significant barriers to entry into the distribution markets in which we operate. As a result, any organization that has adequate financial resources and access to technical expertise can compete for distribution projects. Instead of outsourcing to us, some of our T&D customers also employ personnel internally to perform the same type of services that we provide.

#### C&I Competition

Our C&I segment competes with a number of regional or small local firms and subsidiaries of larger national firms. Competition for our C&I construction services varies greatly. There are few significant barriers to entry in the C&I business, and there are a number of small companies that compete for C&I business. The size, location and technical requirements of the project will impact which competitors and the number of competitors that we will encounter when bidding on any particular project.

A major competitive factor in our C&I segment is the individual relationships that we and our competitors have developed with general contractors who typically manage the bid process. Additionally, the equipment requirements for C&I work are generally not as significant as that of T&D construction. Since C&I construction typically involves the purchase of materials, the financial resources to meet the materials procurement and equipment requirements of a particular project may impact the competition that we encounter. We differentiate ourselves from our competitors by bidding for larger and/or more technically complex projects, which we believe many of our smaller competitors may not be capable of executing

4

TABLE OF CONTENTS

effectively or profitably. We believe that we have a favorable competitive position in the markets that we serve due in part to our strong operating history and strong local market share as well as our reputation and relationships with our customers.

## Project Bonding Requirements

Many customers, particularly in connection with new construction, require us to post performance and payment bonds issued by a financial institution known as a surety. These bonds provide a guarantee to the customer that we will perform under the terms of a contract and that we will pay subcontractors and vendors. If we fail to perform under a contract or to pay subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. We generally must reimburse the surety for any expenses or outlays it incurs. These bonds are typically issued at the face value of the contract awarded. As of December 31, 2015, we had approximately $707.1 million in original face amount of bonds outstanding for projects in our T&D segment and $204.9 million for projects in our C&I segment. Our estimated remaining cost to complete these bonded projects for both segments was approximately $87.0 million as of December 31, 2015. As of December 31, 2014, we had approximately $636.5 million in original face amount of bonds outstanding for projects in our T&D segment and $188.6 million for projects in our C&I segment. The ability to post bonds provides us with a competitive advantage over smaller or less financially secure competitors. We believe that the strength of our balance sheet, as well as our strong and long-standing relationship with our surety, enhances our ability to obtain adequate financing and bonds.

## Backlog

We refer to our estimated revenue on uncompleted contracts, including the amount of revenue on contracts for which work has not begun, less the revenue we have recognized under such contracts, as “backlog.” We calculate backlog differently for different types of contracts. For our fixed-price contracts, we include the full remaining portion of the contract in our calculation of backlog. A customer’s intention to award us work under a fixed-price contract is not included in backlog unless there is an actual award to perform a specific scope of work at specific terms and pricing. For many of our unit-price, time-and-equipment, time-and-materials and cost-plus contracts, we only include projected revenue for a three-month period in the calculation of backlog, although these types of contracts are generally awarded as part of MSAs that typically have a one-year to three-year duration from execution. Given the duration of our contracts and MSAs and our method of calculating backlog, our backlog at any point in time may not accurately represent the revenue that we expect to realize during any period and our backlog as of the end of a fiscal year may not be indicative of the revenue we expect to generate in the following fiscal year and should not be viewed or relied upon as a stand-alone indicator. See “Item 1A. Risk Factors-Backlog may not be realized or may not result in profits and may not accurately represent future revenue.”

Certain projects that we undertake are not completed in one accounting period. Revenue on construction contracts is recorded based upon the percentage-of-completion accounting method, under which revenue is determined by the ratio of costs incurred to date on the contracts (excluding uninstalled direct materials) to management’s estimates of total contract costs. Under the percentage-of-completion method of accounting, revenue recognition is largely a function of contract costs incurred for any given period. Contract costs may include direct material, labor, subcontractor and material procurement services, equipment, and those indirect costs related to contract performance such as indirect labor, supplies, tools and repairs. While our contracts typically include labor, equipment and indirect costs, the amount of subcontractor and material costs on any individual contract can vary considerably.

5

TABLE OF CONTENTS

There can be no assurance as to the accuracy of our customers’ requirements or of our estimates of existing and future needs under MSAs, or of the values of our cost or time-dependent contracts and, therefore, our current backlog may not be realized as part of our future revenues. Subject to the foregoing discussions, the following table summarizes that amount of our backlog that we believe to be firm as of the dates shown and the amount of our current backlog that we reasonably estimate will not be recognized within the next twelve months:

|  | Backlog at December 31, 2015 |  | Total Backlog at December 31, 2014
(in thousands) |  | Total |  | Amount estimated to not be recognized within 12 months
T&D |  | $ | 323,570 |  |  | $ | 22,561 |  |  | $ | 320,435 |
C&I |  |  | 127,364 |  |  |  | 12,907 |  |  |  | 113,206 |
Total |  | $ | 450,934 |  |  | $ | 35,468 |  |  | $ | 433,641 |

Changes in backlog from period to period are primarily the result of fluctuations in the timing of awards and revenue recognition of contracts. The increase in the 2015 backlog was primarily due to acquisitions and expansion into new geographic markets, partially offset by declines in large, multi-year project activity.

## Trade Names and Intellectual Property

We operate in the U.S. under a number of trade names, including MYR Group Inc., The L. E. Myers Co., Harlan Electric Company, Great Southwestern Construction, Inc., Sturgeon Electric Company, Inc., MYR Transmission Services, Inc,. E.S. Boulos Company and High Country Line Construction, Inc. We operate in Canada under the trade names MYR Group Construction Canada, Ltd., MYR Transmission Services Canada, Ltd., and Northern Transmission Services, Ltd. We do not generally register our trade names, but instead rely on statutory and common law protection. While we consider our trade names to be valuable assets, we do not consider any single trade name to be of such material importance that its absence would cause a material disruption to our business. We also do not materially rely upon any patents, licenses or other intellectual property.

## Equipment

Our long history in the T&D industry has allowed us to be instrumental in designing much of the specialty tools and equipment used in the industry, including wire pullers, wire tensioners and aerial devices. We operate a fleet of trucks and trailers, support vehicles, bulldozers, bucket trucks, digger derricks and cranes and specialty construction equipment, such as wire pullers and wire tensioning machines. We also rely on specialized tooling, including stringing blocks, wire grips and presses. The standardization of our trucks and trailers allows us to streamline training, maintenance and parts costs. We operate a centralized fleet facility, as well as 20 regional maintenance shops throughout the United States, which are staffed by over 150 mechanics and equipment managers who service our fleet. Our ability to internally service our fleet in various markets often allows us to reduce repair costs and the time equipment is out of service by eliminating both the need to ship equipment long distances for repair and dependence on third party maintenance providers. Our maintenance shops are also able to modify standard construction equipment to meet the specific needs of our specialty applications. We are a final-stage manufacturer for several configurations of our specialty vehicles, and, in the event that a particular piece of equipment is not available to us, we can build the component on-site, which reduces our reliance on our equipment suppliers.

Our fleet of equipment is managed by our centralized fleet management group. Our fleet is highly mobile, which gives us the ability to shift resources from region-to-region quickly and to effectively respond to customer needs or major weather events. Our centralized fleet management group is designed to enable us to optimize and maintain our equipment to achieve the highest equipment utilization which helps to maintain a competitive position with respect to our equipment costs. We develop internal equipment rates which provide our business units with appropriate pricing levels to estimate their bids for new projects more accurately. We also involve our business units in prioritizing the use of our fleet assets. The fleet management group also

6

TABLE OF CONTENTS

manages the procurement and disposition of equipment and short-term rentals. All of these factors are critical in allowing us to operate efficiently and meet our customers’ needs.

## Regulation

Our operations are subject to various laws and regulations including:

| • | licensing, permitting and inspection requirements applicable to electricians and engineers;

| • | regulations relating to worker safety and environmental protection;

| • | permitting and inspection requirements applicable to construction projects;

| • | building and electrical codes;

| • | special bidding and procurement requirements on government projects; and

| • | local laws and government acts regulating work on protected sites.

We believe that we are in compliance with applicable regulatory requirements and have all material licenses required to conduct our operations. Our failure to comply with applicable regulations could result in project delays, cost overruns, remediation costs, substantial fines and/or revocation of our operating licenses.

## Environmental Matters

As a result of our current and past operations, we are subject to numerous environmental laws and regulations governing our operations, including the use, transport and disposal of non-hazardous and hazardous substances and wastes, as well as emissions and discharges into the environment, including discharges to air, surface water, groundwater and soil. We also are subject to laws and regulations that impose liability and cleanup responsibility for releases of hazardous substances into the environment. Under certain of these laws and regulations, such liabilities can be imposed for cleanup of previously owned or operated properties, or properties to which hazardous substances or wastes were discharged by current or former operations at our facilities, regardless of whether we directly caused the contamination or violated any law at the time of discharge or disposal. The presence of contamination from such substances or wastes could interfere with ongoing operations or adversely affect our ability to sell, lease or otherwise use our properties in certain ways such as collateral for possible financing. We could also be held liable for significant penalties and damages under certain environmental laws and regulations, which could materially and adversely affect our business and results of operations.

We believe that we are in substantial compliance with environmental laws and regulations and that any obligations related to environmental matters should not have a material effect on our financial condition, results of operations and cash flows.

Additionally, there are significant environmental regulations under consideration to encourage the use of clean energy technologies and regulate emissions of greenhouse gases to address climate change. We regularly monitor the various proposals in this regard. Although the impact of climate change regulations on our business will depend on the specifics of governmental policies, legislation, and regulation, we believe that we will be well-positioned to adapt our business to meet new regulations. See “Item 1A. Risk Factors-We are subject to risks associated with climate change” and “Item 1A. Risk Factors-Our failure to comply with environmental and other laws and regulations could result in significant liabilities.”

## Cyclical Nature of Business and Seasonality

The demand for construction and maintenance services from our customers is cyclical in nature and vulnerable to downturns in the industries we serve as well as the economy in general. As a result, our volume of business could be adversely affected by declines or delays in new projects in various geographic regions.

Although our revenues are primarily driven by spending patterns in our customers’ industries, our revenues and results of operations can be subject to seasonal and other variations. These variations are influenced by weather, daylight hours, availability of system outages from utilities and holidays. For example, during the winter months, demand for our T&D work may be high, but our work can be delayed due to inclement weather. During the summer months, the demand for our T&D work may be affected by fewer

7

TABLE OF CONTENTS

available system outages during which we can perform electrical line service work due to peak electrical demands caused by warmer weather conditions. During the spring and fall months, the demand for our T&D work may increase due to improved weather conditions and system availability; however, extended periods of rain and other severe weather can affect the deployment of our crews and efficiency of operations.

## Employees

We seek to attract and retain highly qualified craft employees by providing a superior work environment through our emphasis on safety, our high quality fleet of equipment, and our competitive compensation. The number of individuals we employ varies significantly throughout the year, typically with lower staffing levels at year end and through the winter months when fewer projects are active. The number of craft employees fluctuates depending on the number and size of projects at any particular time. As of December 31, 2015, we had approximately 4,075 employees, consisting of approximately 725 salaried employees, including executive officers, district managers, project managers, superintendents, estimators, office managers, and staff and clerical personnel, and approximately 3,350 craft employees. Approximately 91% of our craft employees were members of unions, with the majority being members of the International Brotherhood of Electrical Workers (“IBEW”), who are represented by many local unions under agreements with generally uniform terms and varying expiration dates. We generally are not direct parties to such local agreements, but instead these agreements are entered into by and between the IBEW local unions and the National Electrical Contractors Association (“NECA”), of which we are a member. NECA negotiates the terms of these agreements on our behalf. On occasion we will also employ individuals who are members of other trade unions pursuant to multi-employer, multi-union project agreements.

# RISK FACTORS

You should read the following risk factors carefully in connection with evaluating our business and the forward-looking information contained in this annual report on Form 10-K. We operate in a changing environment that involves numerous known and unknown risks and uncertainties that could affect our operations. The risks described below highlight some of the factors that have affected, and in the future could affect, our operations. Additional risks we do not yet know of, or that we currently think are immaterial, may also affect our business operations. If any of the events or circumstances described in the following risks actually occurs, our business, financial condition or results of operations could be affected and our stock price could decline.

### Our operating results may vary significantly from period to period.

Our business can be highly cyclical and subject to seasonal and other variations that can result in significant differences in operating results from period to period. Additionally, our results may be materially and adversely affected by:

| • | the timing and volume of work under contract;

| • | increased competition and changes in the competitive marketplace for our services;

| • | the spending patterns of customers and governments;

| • | safety performance and reputation;

| • | the amount of subcontractor and material costs in our projects;

| • | decreased equipment utilization;

| • | permitting, regulatory or customer-caused delays on projects;

| • | disputes with customers relating to payment terms under our contracts and change orders, and our ability to successfully negotiate and obtain payment or reimbursement under our contracts and change orders;

| • | variations in the margins of projects performed during any particular reporting period;

| • | a change in the demand for our services;

| • | increased costs of performance of our services caused by adverse weather conditions;

| • | increases in design and construction costs that we are unable to pass through to our customers;

| • | the termination or expiration of existing agreements;

| • | regional and general economic conditions and the condition of the financial markets;

| • | losses experienced in our operations not otherwise covered by insurance;

| • | a change in the mix of our customers, contracts and business;

| • | payment risk associated with the financial condition of our customers;

| • | cost overruns on fixed-price and unit-price contracts;

| • | availability of qualified labor for specific projects;

| • | changes in bonding requirements applicable to existing and new agreements;

| • | costs we incur to support growth internally or otherwise;

| • | the timing and integration of acquisitions and the magnitude of the related acquisition and integration costs;

| • | costs associated with our multi-employer pension plan obligations;

10

TABLE OF CONTENTS

| • | the availability of equipment;

| • | costs associated with responding to proxy contests and other actions of activist stockholders;

| • | significant fluctuations in foreign currency exchange rates;

| • | impairment of goodwill or intangible assets;

| • | warranty claims; and

| • | changes in accounting pronouncements that require us to account for items differently than historical pronouncements.

Accordingly, our operating results in any particular reporting period may not be indicative of the results that can be expected for any other reporting period.

### Our industry is highly competitive.

Our industry is highly competitive. Increased competition can place downward pressure on contract prices and profit margins and may limit the number of projects that we are awarded. Our industry is fragmented and we compete with other companies, ranging from small, independent firms servicing local markets to larger firms servicing regional, national and international markets. Relatively few barriers prevent entry into the C&I market and the distribution market. As a result, any organization that has adequate financial resources and access to technical expertise may become one of our competitors in those areas. Competition in the industry depends on a number of factors, including price. Some of our competitors, including our competitors in the transmission market, may have lower labor and overhead cost structures and, therefore, may be able to provide their services at lower prices than ours. In addition, some of our competitors may have greater financial, technological and human resources than we do. We cannot be certain that our competitors will not develop the expertise, experience and resources to provide services that are superior in both price and quality to our services. Similarly, we cannot be certain that we will be able to maintain or enhance our competitive position within the markets we serve or maintain our customer base at current levels. We also may face competition from in-house service organizations of our existing or prospective customers. Electric utility companies often employ personnel to internally perform some of the same types of services we do. If we are unable to compete successfully in our markets, our operating results could be adversely affected.

### We may be unsuccessful in generating internal growth.

Our ability to generate internal growth will be affected by, among other factors, our ability to:

| • | attract new customers;

| • | increase the number of projects performed for existing customers;

| • | hire and retain qualified personnel;

| • | successfully bid new projects;

| • | expand geographically; and

| • | adapt the range of services we offer to customers to address their evolving construction needs.

In addition, if our customers are constrained in their ability to obtain capital, it could reduce the number, timing or size of projects available to us. Many of the factors affecting our ability to generate internal growth may be beyond our control, and we cannot be certain that our strategies will be successful, or that we will be able to generate cash flow sufficient to fund our operations and to support internal growth. If we are unsuccessful, we may not be able to achieve internal growth, expand our operations or grow our business.

### Negative economic and market conditions, as well as regulatory and environmental requirements, may adversely impact our customers’ future spending and, as a result, our operations and growth.

The demand for infrastructure construction and maintenance services from our customers has been, and will likely continue to be, cyclical in nature and vulnerable to downturns in the industries we serve as well as the economy in general. Stagnant or declining economic conditions have adversely impacted the demand for

11

TABLE OF CONTENTS

our services in the past and resulted in the delay, reduction or cancellation of certain projects and may adversely affect us in the future. Unfavorable economic conditions could also cause our customers to outsource less work. Additionally, many of our customers finance their projects through the incurrence of debt or the issuance of equity. A reduction in cash flow or the lack of availability of debt or equity financing may result in a reduction in our customers’ spending for our services and may also impact the ability of our customers to pay amounts owed to us, which could have a material adverse effect on our operations and our ability to grow at historical levels. A prolonged economic downturn or recession could adversely affect our customers and their ability or willingness to fund capital expenditures in the future or pay for past services. Material fluctuations in energy markets could have an adverse impact on our customers’ spending patterns. Consolidation, competition, capital constraints or negative economic conditions in the electric power industry may also result in reduced spending by, or the loss of, one or more of our customers.

Because the vast majority of our T&D revenue is derived from the electric utility industry, regulatory and environmental requirements affecting that industry could adversely affect our results of operations. Customers in the electric utility industry we serve face stringent regulatory and environmental requirements as well as permitting processes as they implement plans for their projects, which may result in delays, reductions and cancellations of some of their projects. These regulatory factors have resulted in decreased demand for our services in the past, and they may do so in the future, potentially impacting our operations and our ability to grow at historical levels.

### Project performance issues, including those caused by third parties, or certain contractual obligations may result in additional costs to us, reductions or delays in revenues or the payment of penalties, including liquidated damages.

Many projects involve challenging engineering, procurement and construction phases that may occur over several years. We may encounter difficulties that impact our ability to complete the project in accordance with the original delivery schedule. These difficulties may be the result of delays in designs, engineering information or materials provided by the customer or a third party, delays or difficulties in equipment and material delivery, schedule changes, delays from our customer’s failure to timely obtain permits or rights-of-way or meet other regulatory requirements, weather-related delays, delays caused by difficult worksite environments and other factors, some of which are beyond our control. In addition, for some projects we contract with third-party subcontractors to assist us with the completion of contracts. Any delay or failure by suppliers or by subcontractors in the completion of their portion of the project may result in delays in the overall progress of the project or may cause us to incur additional costs, or both. We also may encounter project delays due to local opposition, which may include injunctive actions as well as public protests, to the siting of electric transmission lines, renewable energy projects, or other facilities. We may not be able to recover the costs we incur that are caused by delays. In certain circumstances, we guarantee project completion by a scheduled acceptance date or achievement of certain acceptance and performance testing levels. Failure to meet any of our schedules or performance requirements could also result in additional costs or penalties, including liquidated damages, and such amounts could exceed expected project profit. In extreme cases, the above-mentioned factors could cause project cancellations, and we may not be able to replace such projects with similar projects or at all. Such delays or cancellations may impact our reputation or relationships with customers, adversely affecting our ability to secure new contracts.

Our customers may change or delay various elements of the project after its commencement. The design, engineering information, equipment or materials that are to be provided by the customer or other parties may be deficient or delivered later than required by the project schedule, resulting in additional direct or indirect costs. Under these circumstances, we generally negotiate with the customer with respect to the amount of additional time required and the compensation to be paid to us. We are subject to the risk that we may be unable to obtain, through negotiation, arbitration, litigation or otherwise, adequate amounts to compensate us for the additional work or expenses incurred by us due to customer-requested change orders or failure by the customer to timely deliver items, such as engineering drawings or materials. Litigation or arbitration of claims for compensation may be lengthy and costly, and it is often difficult to predict when and for how much the claims will be resolved. A failure to obtain adequate compensation for these matters could require us to record a reduction to amounts of revenue and gross profit recognized in prior periods under the percentage-of-completion accounting method. Any such adjustments could be substantial. We may also

12

TABLE OF CONTENTS

be required to invest significant working capital to fund cost overruns while the resolution of change orders or claims is pending, which could adversely affect our liquidity and financial results in any given period.

### Our business is labor intensive and we may be unable to attract and retain qualified employees.

Our ability to maintain our productivity and our operating results may be limited by our ability to employ, train and retain skilled personnel necessary to meet our requirements. We may not be able to maintain an adequate skilled labor force necessary to operate efficiently and to support our growth strategy. We have from time-to-time experienced shortages of certain types of qualified personnel, such as engineers, project managers, field supervisors, and linemen, in certain regions. In addition, our projects are sometimes located in remote areas which can make recruitment and deployment of our employees challenging. During periods with large volumes of storm restoration services work, linemen are frequently recruited across geographic regions to satisfy demand. Many linemen are willing to travel to earn premium wages for such work, which from time-to-time makes it difficult for us to retain these workers for ongoing projects when storm conditions persist. The supply of experienced engineers, project managers, field supervisors, linemen and other skilled workers may not be sufficient to meet current or expected demand. The commencement of new, large-scale infrastructure projects or increased demand for infrastructure improvements, as well as the shrinking electric utility workforce, may reduce the pool of skilled workers available to us. Labor shortages could impair our ability to maintain our business or grow our revenues. If we are unable to hire employees with the requisite skills, we may also be forced to incur significant training expenses.

### The timing of new contracts and termination of existing contracts may result in unpredictable fluctuations in our cash flows and financial results.

A substantial portion of our revenues are derived from project-based work that is awarded through a competitive bid process. It is generally very difficult to predict the timing and geographic distribution of the projects that we will be awarded. The selection of, timing of, or failure to obtain projects, delays in awards of projects, the re-bidding or termination of projects due to budget overruns, cancellations of projects or delays in completion of contracts could result in the under-utilization of our assets, including our fleet of construction equipment, which could lower our overall profitability and reduce our cash flows. Even if we are awarded contracts, we face additional risks that could affect whether, or when, work will begin. This can present difficulty in matching workforce size and equipment location with contract needs. In some cases, we may be required to bear the cost of a ready workforce and equipment that is larger than necessary, which could impact our cash flow, expenses and profitability. If an expected contract award or the related work release is delayed or not received, we could incur substantial costs without receipt of any corresponding revenues. Moreover, construction projects for which our services are contracted may require significant expenditures by us prior to receipt of relevant payments from the customer. Finally, the winding down or completion of work on significant projects that were active in previous periods will reduce our revenue and earnings if such significant projects have not been replaced in the current period.

Many of our contracts may be canceled upon short notice, typically 30 to 90 days, even if we are not in default under the contract, and we may be unsuccessful in replacing our contracts if they are canceled or as they are completed or expire. We could experience a decrease in our revenue, net income and liquidity if contracts are canceled and if we are unable to replace canceled, completed or expired contracts. Certain of our customers assign work to us on a project-by-project basis under MSAs. Under these agreements, our customers often have no obligation to assign a specific amount of work to us. Our operations could decline significantly if the anticipated volume of work is not assigned to us or is cancelled. Many of our contracts, including our MSAs, are opened to competitive bid at the expiration of their terms. There can be no assurance that we will be the successful bidder on our existing contracts that come up for re-bid.

### Backlog may not be realized or may not result in profits and may not accurately represent future revenue.

Backlog is difficult to determine accurately, and companies within our industry may define backlog differently. Reductions in backlog due to cancellation, termination or scope adjustment by a customer or for other reasons could significantly reduce the revenue and profit we actually receive from contracts in backlog. In the event of a project cancellation, termination or scope adjustment, we typically have no contractual right to the total revenues reflected in our backlog. The timing of contract awards, duration of large new contracts

13

TABLE OF CONTENTS

and the mix of services, subcontracted work and material in our contracts can significantly affect backlog reporting. Given these factors and our method of calculating backlog, our backlog at any point in time may not accurately represent the revenue that we expect to realize during any period, and our backlog as of the end of a fiscal year may not be indicative of the revenue we expect to earn in the following fiscal year and should not be viewed or relied upon as a stand-alone indicator. Consequently, we cannot provide assurance as to our customers’ requirements or our estimates of backlog. See “Item 1. Business-Backlog” for a discussion on how we calculate backlog for our business.

### Our business growth could outpace the capability of our internal resources.

Our internal resources, including our workforce, specialized equipment and financial resources may not be adequate to support our operations as they expand, particularly if we are awarded a significant number of large projects in a short time period. A large project may require hiring additional qualified personnel, such as engineers, project managers, field supervisors, linemen and safety personnel, the supply of which may not be sufficient to meet our demands.

Often large transmission projects require specialized equipment. To the extent that we are unable to buy or build equipment necessary for a project, either due to a lack of available funding or equipment shortages in the marketplace, we may be forced to rent equipment on a short-term basis or to find alternative ways to perform the work without the benefit of equipment ideally suited for the job, which could increase the costs of completing the project. Furthermore, we may be unable to buy or rent the specialty equipment and tooling we require due to the limited number of manufacturers and distributors in the marketplace.

Larger projects may require substantial financial resources to meet the cash flow, bonding or letter of credit requirements imposed upon contractors by the customer. Future growth also could impose additional demands and responsibilities on members of our senior management.

### Our dependence on suppliers, subcontractors and equipment manufacturers could expose us to the risk of loss in our operations.

On certain projects, we rely on suppliers to obtain the necessary materials and subcontractors to perform portions of our services. We also rely on equipment manufacturers to provide us with the equipment required to conduct our operations. Although we are not dependent on any single supplier, subcontractor or equipment manufacturer, any substantial limitation on the availability of required suppliers, subcontractors or equipment manufacturers could negatively impact our operations. The risk of a lack of available suppliers, subcontractors or equipment manufacturers may be heightened as a result of market and economic conditions. To the extent we cannot engage subcontractors or acquire equipment or materials, we could experience losses in the performance of our operations. Additionally, successful completion of our contracts may depend on whether our subcontractors successfully fulfill their contractual obligations. If our subcontractors fail to perform their contractual obligations as a result of financial or other difficulties, or if our subcontractors fail to meet the expected completion dates or quality standards, we may be required to incur additional costs or provide additional services in order to make up such shortfall and we may suffer damage to our reputation.

### Our participation in joint ventures and other projects with third parties may expose us to liability for failures of our partners.

We may enter into joint venture or other strategic arrangements with other parties as part of our business operations. Success on a jointly performed project depends in large part on whether all parties satisfy their contractual obligations. Joint venture partners are generally jointly and severally liable for all liabilities and obligations of the joint venture. If a joint venture partner fails to perform or is financially unable to bear its portion of required capital contributions or other obligations, including liabilities relating to claims or lawsuits, we could be required to make additional investments, provide additional services or pay more than our proportionate or agreed upon share of a liability to compensate for the partner’s shortfall. In addition, if we are unable to adequately address our partner’s performance issues, the customer may terminate the project, which could result in legal liability to us, reduce our profit on the project or damage our reputation.

TABLE OF CONTENTS

### Legislative or regulatory actions relating to electricity transmission and renewable energy may impact demand for our services.

Current and potential legislative or regulatory actions may impact demand for our services. Certain legislation or regulations require utilities to meet reliability standards and encourage installation of new electric transmission and renewable energy generation facilities. However, it is unclear whether these initiatives will create sufficient incentives for projects or result in increased demand for our services.

While many states have mandates in place that require specified percentages of electricity to be generated from renewable sources, states could reduce those mandates or make them optional, which could reduce, delay or eliminate renewable energy development in the affected states. Additionally, renewable energy is generally more expensive to produce and may require additional power generation sources as backup. The locations of renewable energy projects are often remote and may not be viable unless new or expanded transmission infrastructure to transport the electricity to demand centers is economically feasible. Furthermore, funding for renewable energy initiatives may not be available. These factors could result in fewer renewable energy projects and a delay in the construction of these projects and the related infrastructure, which could negatively impact our business.

### Our use of percentage-of-completion accounting could result in a reduction or reversal of previously recognized profits.

As discussed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results from Operations — Critical Accounting Policies” and in the notes to our Financial Statements, a significant portion of our revenues is recognized on a percentage-of-completion method of accounting, using the cost-to-cost method. This method is used because management considers expended costs to be the best available measure of progress on these contracts. This accounting method is commonly used in the construction industry for fixed-price contracts. The percentage-of-completion accounting practice we use 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 contracts are based on estimates of contract revenues, costs and profitability. Contract losses are recognized in full when determined, and contract profit estimates are adjusted based on ongoing reviews of contract profitability. In addition, we record adjustments to estimated costs of contracts when we believe the change in estimate is probable and the amounts can be reasonably estimated. These adjustments could result in both increases and decreases in profit margins. Actual results could differ from estimated amounts and could result in a reduction or elimination of previously recognized earnings.

### Our actual costs may be greater than expected in performing our fixed-price and unit-price contracts.

We currently generate, and expect to continue to generate, a significant portion of our revenues and profits under fixed-price and unit-price contracts. We must estimate the costs of completing a particular project when we bid for these types of contracts. The actual cost of labor and materials, however, may vary from the costs we originally estimated and we may not be successful in recouping additional costs from our customers. These variations, along with other risks inherent in performing fixed-price and unit-price contracts, may cause actual revenue and gross profits for a project to differ from those we originally estimated and could result in reduced profitability or losses on projects due to changes in a variety of factors such as:

| • | failure to properly estimate costs of engineering, material, equipment or labor;

| • | unanticipated technical problems with the materials or services being supplied by us, which may require us to incur additional costs to remedy the problem;

| • | project modifications that create unanticipated costs;

| • | changes in the costs of equipment, materials, labor or subcontractors;

| • | the failure of our suppliers or subcontractors to perform;

| • | difficulties in our customers obtaining required governmental permits or approvals;

| • | site conditions that differ from those assumed in the original bid (to the extent contract remedies are unavailable);

15

TABLE OF CONTENTS

| • | the availability and skill level of workers in the geographic location of the project;

| • | an increase in the cost of fuel or other resources;

| • | changes in local laws and regulations;

| • | delays caused by local weather conditions, third parties or customers; or

| • | quality issues requiring rework.

### Our financial results are based upon estimates and assumptions that may differ from actual results.

In preparing our financial statements in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”), estimates and assumptions are used by management in determining the reported amounts of assets and liabilities, revenues and expenses recognized during the periods presented and disclosures of contingent assets and liabilities known to exist as of the date of the financial statements. These estimates and assumptions must be made because certain information that is used in the preparation of our financial statements is dependent on future events, cannot be calculated with a high degree of precision from data available or is not capable of being readily calculated. In some cases, these estimates are particularly difficult to determine, and we must exercise significant judgment.

The most significant estimates we use are related to costs to complete on contracts, insurance reserves, estimates surrounding stock-based compensation, the recoverability of goodwill and intangibles, and accounts receivable reserves. We also may use estimates in our assessment of the useful lives of property and equipment, the valuation allowance on deferred taxes and the provision for income taxes. From time-to-time, we may publicly provide earnings or other forms of guidance, which reflect our predictions about future revenue, operating costs and capital structure, among other factors. These predictions may be impacted by estimates, as well as other factors that are beyond our control and may not turn out to be correct. Actual results for all estimates could differ materially from the estimates and assumptions that we use.

We maintain insurance policies with respect to automobile liability, general liability, workers’ compensation, employers’ liability and other coverages, but those policies do not cover all possible claims and are subject to certain deductible limits. We also have an employee health care benefit plan for employees not subject to collective bargaining agreements, which is subject to certain deductible limits. Insurance losses are accrued based upon our estimates of the ultimate liability for claims reported and an estimate of claims incurred but not yet reported. 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 not reported and the effectiveness of our safety programs, and as a result, our actual losses may exceed our estimates.

### The loss of a key customer could have an adverse affect on us.

Our customer base is highly concentrated, with our top ten customers accounting for 44.6% of our revenue for the year ended December 31, 2015. Much of our success depends on developing and maintaining relationships with our major customers. Our revenue could significantly decline if we lose one or more of our significant customers. In addition, revenues generated from contracts with significant customers may vary from period-to-period depending on the timing and volume of work ordered by such customers in a given period and as a result of competition from the in-house service organizations of our customers.

### Our failure to comply with environmental and other laws and regulations could result in significant liabilities.

Our past, current and future operations are subject to numerous environmental and other laws and regulations governing our operations, including the use, transport and disposal of non-hazardous and hazardous substances and wastes, as well as emissions and discharges into the environment, including discharges to air, surface water, groundwater and soil. We also are subject to laws and regulations that impose liability and cleanup responsibility for releases of hazardous substances into the environment. Under certain of these laws and regulations, such liabilities can be imposed for cleanup of previously owned or operated properties, or properties to which hazardous substances or wastes were discharged by current or former

16

TABLE OF CONTENTS

operations at our facilities, regardless of whether we directly caused the contamination or violated any law at the time of discharge or disposal. The presence of contamination from such substances or wastes could interfere with ongoing operations or adversely affect our ability to sell, lease or otherwise use our properties in ways such as collateral for possible financing. We could also be held liable for significant penalties and damages under certain environmental laws and regulations, which could materially and adversely affect our business and results of operations.

In addition, new laws and regulations, stricter enforcement of existing laws and regulations, the discovery of previously unknown contamination or leaks, or the imposition of new permitting or cleanup requirements could require us to incur significant costs or become the basis for new or increased liabilities that could harm our financial condition and results of operations. In certain instances, we have obtained indemnification or covenants from third parties (including our predecessor owners or lessors) for some or all of such cleanup and other obligations and liabilities. However, such third-party indemnities or covenants may not cover all of our costs.

Legislative and regulatory proposals related to address greenhouse gas emissions could result in a variety of regulatory programs, additional charges to fund energy efficiency activities, or other regulatory actions. Any of these actions could result in increased costs associated with our operations and impact the prices we charge our customers. If new regulations are adopted regulating greenhouse gas emissions from mobile sources such as cars and trucks, we could experience a significant increase in environmental compliance costs in light of our large fleet. In addition, if our operations are perceived to result in high greenhouse gas emissions, our reputation could suffer.

In addition, we are subject to laws and regulations protecting endangered species. Laws also protect Native American artifacts and archaeological sites and a part of our business is operated in the southwestern United States, where there is a greater chance of discovering those sites. We may incur work stoppages to avoid violating these laws and regulations, or we may risk fines or other sanctions for accidentally or willfully violating these laws and regulations.

### Unavailability or cancellation of third party insurance coverage would increase our overall risk exposure and could disrupt our operations.

We maintain insurance coverage from third party insurers as part of our overall risk management strategy and because some of our contracts require us to maintain specific insurance coverage limits. Although we maintain insurance policies with respect to automobile liability, general liability, workers’ compensation, our employee group health program, and other types of coverage, these policies are subject to high deductibles, and we are self-insured up to the amount of those deductibles. There can be no assurance that our current or past insurance coverage will be sufficient or effective under all circumstances or against all claims and liabilities to which we may be subject.

We renew our insurance policies on an annual basis; therefore, deductibles and levels of insurance coverage may change in future periods. There can be no assurance that any of our existing insurance coverage will be renewed upon the expiration of the coverage period or that future coverage will be affordable at the required limits. In addition, our current or past third party insurers may fail, cancel our coverage, determine to exclude certain items from coverage, or otherwise be unable to provide us with adequate insurance coverage. We may not be able to obtain certain types of insurance or incremental levels of insurance in scope or amount sufficient to cover liabilities we may incur.

If any of these events occur, our overall risk exposure would increase and our operations could be disrupted. If our risk exposure increases as a result of adverse changes in our insurance coverage, we could be subject to increased claims and liabilities that could negatively affect our results of operations and financial condition.

### We may incur liabilities and suffer negative financial or reputational impacts relating to occupational health and safety matters.

Our operations are subject to extensive laws and regulations relating to the maintenance of safe conditions in the workplace. While we have invested, and will continue to invest, substantial resources in our occupational health and safety programs, our industry involves a high degree of operational risk, and there can

17

TABLE OF CONTENTS

be no assurance that we will avoid significant liability exposure. Our business is subject to numerous safety risks, including electrocutions, fires, explosions, mechanical failures, weather-related incidents, transportation accidents and damage to equipment. These hazards can cause personal injury and loss of life, severe damage to or destruction of property and equipment and other consequential damages and could lead to suspension of operations, large damage claims and, in extreme cases, criminal liability. We have suffered serious injuries and fatalities in the past and may suffer additional serious injuries and fatalities in the future. Claims for damages to persons, including claims for bodily injury or loss of life, could result in substantial costs and liabilities. In addition, we have in the past, and we may in the future, be subject to criminal penalties relating to occupational health and safety violations, which have resulted in and could in the future result in substantial costs and liabilities. Any of the foregoing could result in financial loss, which could have a material adverse impact on our business, financial condition, results of operations and cash flows.

Our customers seek to minimize safety risks on their sites, and they frequently review the safety records of outside contractors during the bidding process. If our safety record were to substantially deteriorate, we might become ineligible to bid on certain work, and our customers could cancel our contracts and not award us future business.

### We extend trade credit to customers for purchases of our services, and may have difficulty collecting receivables from them.

We grant trade credit, generally without collateral, to our customers for the purchase of our services. We have in the past, and may in the future, have difficulty collecting receivables from customers, particularly those experiencing financial difficulties. Our customers in the T&D segment include investor-owned utilities, cooperatives, private developers, government-funded utilities, independent power producers, independent transmission companies, industrial facility owners and other contractors. Our customers in the C&I segment include general contractors, commercial and industrial facility owners, local governments and developers located in our regional markets. Our customers also include special purpose entities that own T&D projects which do not have the financial resources of traditional transmission utility operators. Consequently, we are subject to potential credit risk related to changes in business and economic factors. Due to our work on large construction projects, a few customers sometimes may comprise a large portion of our receivable balance at any point in time. If any of our major customers experience financial difficulties, we could experience reduced cash flows and losses in excess of current allowances provided. In addition, material changes in any of our customers’ revenues or cash flows could affect our ability to collect amounts due from them.

### We may not be able to compete for, or work on, certain projects if we are not able to obtain any necessary bonds, letters of credit, bank guarantees or other financial assurances.

Our contracts may require that we provide to our customers security for the performance of their projects in the form of bonds, letters of credit, bank guarantees or other financial assurances. Current or future market conditions, including losses incurred in the construction industry or as a result of large corporate bankruptcies, as well as changes in our sureties’ assessment of our operating and financial risk, could cause our surety providers and lenders to decline to issue or renew, or substantially reduce the amount of, bid or performance bonds for our work and could increase our costs associated with collateral. These actions could be taken on short notice. If our surety providers or lenders were to limit or eliminate our access to bonding, letters of credit or guarantees, our alternatives would include seeking capacity from other sureties and lenders, finding more business that does not require bonds or allows for other forms of collateral for project performance, such as cash. We may be unable to secure these alternatives in a timely manner, on acceptable terms, or at all, which could affect our ability to bid for or work on future projects requiring financial assurances.

We have also granted security interests in various of our assets to collateralize our obligations to our sureties and lenders. Furthermore, under standard terms in the surety market, sureties issue or continue bonds on a project-by-project basis and can decline to issue bonds at any time or require the posting of additional collateral as a condition to issuing or renewing any bonds. If we were to experience an interruption or reduction in the availability of bonding capacity as a result of these or any other reasons, we may be unable to compete for or work on certain projects that would require bonding.

### Inability to hire or retain key personnel could disrupt our business.

The success of our business depends upon the continued efforts and abilities of our executive officers and senior management, including the management at each operating subsidiary. The relationships between our executive officers and senior management and our customers are important to obtaining and retaining business. We are also dependent upon our project managers and field supervisors who are responsible for managing and recruiting employees to our projects. There can be no assurance that any individual will continue in his or her capacity for any particular period of time. Industry-wide competition for managerial talent is high. Given that level of competition, there could be situations where our overall compensation package may be viewed as less attractive as compared to our competition, and we may experience the loss of key personnel. The loss of key personnel, or the inability to hire and retain qualified employees, could negatively impact our ability to manage our business and relationships with our customers.

### Work stoppages or other labor issues with our unionized workforce could adversely affect our business.

As of December 31, 2015, approximately 91% of our craft labor employees were covered by collective bargaining agreements. Although the majority of these agreements prohibit strikes and work stoppages, we cannot be certain that strikes or work stoppages will not occur in the future. Strikes or work stoppages could adversely impact our relationships with our customers and could cause us to lose business, resulting in decreased revenues.

### Multi-employer pension plan obligations related to our unionized workforce could adversely impact our earnings.

Our collective bargaining agreements may require us to participate with other companies in various multi-employer pension plans. To the extent that we participate in any multi-employer pension plans that are underfunded, the Employee Retirement Income Security Act of 1974, as amended by the Multi-Employer Pension Plan Amendments Act of 1980, may subject us to substantial liabilities under those plans if we were to withdraw from them, if they were terminated or experience a mass withdrawal. Furthermore, the Pension Protection Act of 2006, as amended by the Consolidated and Further Continuing Appropriations Act of 2015 (the “PPA”) imposes additional funding and operational rules applicable to plan years beginning after 2007 for multi-employer pension plans that are classified as either “endangered,” “seriously endangered” or “critical” status. Plans in these classifications must adopt measures to improve their funded status, which may require additional employer contributions and/or modifications to employee benefits based on future union wages paid.

We have been informed that several of the multi-employer pension plans to which our subsidiaries contribute have been classified as “critical” or “endangered” status as defined by the PPA. Although we are not currently aware of any potential significant liabilities to us as a result of these plans being classified as being in a “critical” or “endangered” status, our future financial results could be impacted by the amended funding rules.

### We may fail to execute or integrate acquisitions or joint ventures successfully.

As part of our growth strategy, we may acquire companies or enter into joint ventures that expand, complement or diversify our business. The number of acquisition targets or joint venture opportunities that meet our criteria may be limited, and we may face competition for these opportunities. Acquisitions or joint ventures that we may pursue may also involve significant cash expenditures, the incurrence or assumption of debt or burdensome regulatory requirements.

Future acquisitions or joint ventures may expose us to operational challenges and risks, including the diversion of management’s attention from our existing business, the failure to retain key personnel or customers of an acquired business, difficulties integrating the operations and personnel, failure of acquired companies to achieve the results we expect, the assumption of unknown liabilities of the acquired business for which there are inadequate reserves and the potential impairment of acquired intangible assets. Our ability to grow and maintain our competitive position may be affected by our ability to successfully integrate any businesses acquired.

### Our business may be affected by seasonal and other variations, including severe weather conditions.

Although our revenues are primarily driven by spending patterns in our customers’ industries, our revenues and results of operations can be subject to seasonal variations, particularly in our T&D segment. These variations are influenced by weather, hours of daylight, customer spending patterns, available system outages from utilities and holidays, and can have a significant impact on our gross margins. Our profitability may decrease during the winter months and during severe weather conditions because work performed during these periods may be restricted and more costly to complete. Additionally, our T&D customers often cannot remove their T&D lines from service during the summer months when consumer demand for electricity is at its peak, delaying the demand for our maintenance and repair services. Working capital needs are also influenced by the seasonality of our business. We generally experience a need for additional working capital during the spring when we increase outdoor construction in weather-affected regions of the country, and we convert working capital assets to cash during the winter months.

### We may not have access in the future to sufficient funding to finance desired growth and operations.

If we cannot secure funds in the future, including financing on acceptable terms, we may be unable to support our growth strategy or future operations. Our principal sources of cash are our operating activities and borrowing availability under our credit facility, which expires on December 21, 2016. Our credit facility contains numerous covenants and requires us to meet and maintain certain financial ratios and other tests. General business and economic conditions may affect our ability to comply with these covenants or meet those financial ratios and other tests, which may limit our ability to borrow under the facility. We anticipate that we will be able to renew our credit facility before it expires, but we can give no assurance that we can do so on favorable terms, if at all.

Restrictions in the availability of bank credit could cause us to forgo otherwise attractive business opportunities and could require us to modify our business plan. We will continue to closely monitor our liquidity and the overall condition of the financial markets; however, we can give no assurance that we will be able to obtain such financing either on favorable terms or at all in the future.

### Our operations are subject to a number of operational risks which may result in unexpected costs or liabilities.

Unexpected costs or liabilities may arise from lawsuits or indemnity claims related to the services we perform or have performed in the past. We have in the past been, and may in the future be, named as a defendant in lawsuits, claims and other legal proceedings during the ordinary course of our business. These actions may seek, among other things, compensation for alleged personal injury, workers’ compensation, employment discrimination, breach of contract, property damage, environmental remediation, punitive damages, civil penalties or other losses, consequential damages or injunctive or declaratory relief. In addition, pursuant to our service arrangements, we generally indemnify our customers for claims related to the services we provide under those service arrangements. In some instances, our services are integral to the operation and performance of the electric distribution and transmission infrastructure. As a result, we may become subject to lawsuits or claims for any failure of the systems we work on, even if our services are not the cause for such failures. In addition, we may incur civil and criminal liabilities to the extent that our services contributed to any personal injury or property damage. The outcome of any of these lawsuits, claims or legal proceedings could result in significant costs and diversion of managements’ attention to the business.

### Opportunities associated with government contracts could lead to increased governmental regulation applicable to us.

Most government contracts are awarded through a regulated competitive bidding process. If we were to be successful in being awarded government contracts, significant costs could be incurred by us before any revenues were realized from these contracts. Government agencies may review a contractor’s performance, cost structure and compliance with applicable laws, regulations and standards. If government agencies determine through these reviews that costs were improperly allocated to specific contracts, they will not reimburse the contractor for those costs or may require the contractor to refund previously reimbursed costs. If government agencies determine that we engaged in improper activity, we may be subject to civil and

20

TABLE OF CONTENTS

criminal penalties. Government contracts are also subject to renegotiation of profit and termination by the government prior to the expiration of the term.

### Risks associated with operating in the Canadian market could restrict our ability to expand and harm our business and prospects.

We do not have extensive experience operating in Canada and there are numerous inherent risks in conducting our business in a different country including, but not limited to, potential instability in markets, political, economic or social conditions, and difficult or additional legal and regulatory requirements applicable to our operations. Limits on our ability to repatriate earnings, exchange controls, and complex U.S. and Canadian laws and treaties could also adversely impact our operations. Changes in the value of the Canadian dollar could increase or decrease the U.S. dollar value of our profits earned or assets held in Canada or potentially limit our ability to reinvest earnings from our operations in Canada to fund the financing requirements of our operations in the U.S. These risks could restrict our ability to provide services to Canadian customers or to operate our Canadian business profitably, and could negatively impact our results.

### Our failure to comply with the laws applicable to our Canadian activities, including the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws could have an adverse effect on us.

The U.S. Foreign Corrupt Practices Act (“FCPA”) and similar anti-bribery laws in other jurisdictions prohibit U.S.-based companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or retaining business. Our policies mandate compliance with all applicable anti-bribery laws. Although we have policies and procedures designed to ensure that we, our employees, our agents and others who work with us in foreign countries comply with the FCPA and other anti-bribery laws, there is no assurance that such policies or procedures will protect us against liability under the FCPA or other laws for actions taken by our agents, employees and intermediaries. If we are found to be liable for FCPA violations (either due to our own acts or inadvertence, or due to the acts or inadvertence of others), we could suffer from severe criminal or civil penalties or other sanctions, which could have a material adverse effect on our reputation, business, results of operations, financial condition or cash flows. In addition, detecting, investigating and resolving actual or alleged FCPA violations is expensive and could consume significant time and attention of our senior management.

### The nature of our business exposes us to warranty claims, which may reduce our profitability.

Under our contracts with customers, we typically provide a warranty for the services we provide, guaranteeing the work performed against defects in workmanship and material. As much of the work we perform is inspected by our customers for any defects in construction prior to acceptance of the project, the warranty claims that we have historically received have been minimal. Additionally, materials used in construction are often provided by the customer or are warranted against defects from the supplier. However, certain projects may have longer warranty periods and include facility performance warranties that may be broader than the warranties we generally provide. In these circumstances, if warranty claims occurred, it could require us to re-perform the services or to repair or replace the warranted item, at a cost to us, and could also result in other damages if we are not able to adequately satisfy our warranty obligations. In addition, we may be required under contractual arrangements with our customers to warrant any defects or failures in materials we provide that we purchase from third parties. While we generally require suppliers to provide us warranties that are consistent with those we provide to the customers, if any of these suppliers default on their warranty obligations to us, we may incur costs to repair or replace the defective materials for which we are not reimbursed. Costs incurred as a result of warranty claims could adversely affect our operating results, financial condition and cash flows.

### Certain provisions in our organizational documents and Delaware law could delay or prevent a change in control of our company.

The existence of certain provisions in our organizational documents and Delaware law could delay or prevent an unsolicited change in control of our company, even if a change of control might be beneficial to our shareholders. For example, provisions in our certificate of incorporation and by-laws that could delay or prevent a change in control of our company include: a staggered board of directors, the potential of our board

21

TABLE OF CONTENTS

of directors to authorize the issuance of preferred stock, the power of a majority of our board of directors to fix the number of directors, the power of our board of directors to fill a vacancy on the board of directors, including when such vacancy occurs as a result of an increase in the number of directors, the requirement that actions to be taken by our stockholders may be taken only at an annual or special meeting of our stockholders and not by written consent, and advance notice provisions for director nominations or business to be considered at a stockholder meeting. In addition, Delaware law imposes restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock, an “interested” stockholder, and prohibits us from engaging in any of a broad range of business transactions with an “interested” stockholder for a period of three years following the date such stockholder became classified as an “interested” stockholder.

### We, or our business partners, may be subject to failures, interruptions or breaches of information technology systems, which could affect our operations, competitive position or damage our reputation.

We use our own information technology systems as well as our business partners’ systems to maintain certain data and provide reports. The failure of these systems to operate effectively or problems with transitioning to upgraded or replacement systems could cause delays and reduce the efficiency of our operations, which could have a material adverse effect on our results of operations, and significant capital investments could be required to remediate the problem. Additionally, our security measures, and those of our business partners, may be compromised as a result of third-party security breaches, employee error, malfeasance, faulty password management, or other irregularity, and may result in persons obtaining unauthorized access to our data or accounts. While we devote significant resources to network security and other security measures to protect our systems and data, these security measures cannot provide absolute security. If an informational technology security breach affects our systems, or results in the unauthorized release of our proprietary information, our competitive situation or our reputation could be damaged.

### Our stock price and trading volume may be volatile and future sales of our common stock could lead to dilution of our issued and outstanding common stock.

From time to time, the price and trading volume of our common stock, as well as the stock of other companies in our industry, may experience periods of significant volatility. Company-specific issues and developments generally in our industry (including the regulatory environment) and the capital markets and the economy in general may cause this volatility. We may issue equity securities in the future, including securities that are convertible into or exchangeable for, or that represent the right to receive, common stock. The issuance of additional shares of our common stock or other equity securities, including sales of shares in connection with any future acquisitions, could be substantially dilutive to our stockholders.

### We are subject to risks associated with climate change.

Climate change may create physical and financial risk. Physical risks from climate change could, among other things, include an increase in extreme weather events (such as floods or hurricanes), rising sea levels and limitations on water availability and quality. Such extreme weather conditions may limit the availability of resources, increasing the costs of our projects, or may cause projects to be delayed or cancelled.

Additionally, legislative and regulatory responses related to climate change and new interpretations of existing laws through climate change litigation may also negatively impact our operations. The cost of additional environmental regulatory requirements could impact the availability of goods and increase our costs. International treaties or accords could also have an impact on our business to the extent they lead to future governmental regulations. Compliance with any new laws or regulations regarding the reduction of greenhouse gases could result in significant changes to our operations and a significant increase in our cost of conducting business.

| Item 2. | Properties

Our principal executive offices are located at 1701 Golf Road, Suite 3-1012, Rolling Meadows, Illinois 60008, the lease term of which expires on January 31, 2020. In addition to our executive offices, our corporate accounting and finance departments, corporate information technology department and certain legal and other personnel are located at this office. As of December 31, 2015, we owned 16 operating facilities and leased many other properties in various locations throughout our service territory. Most of our properties are used as offices or for fleet operations. We believe that our facilities are adequate for our current operating needs. We do not believe that any owned or leased facility is material to our operations and, if necessary, we could obtain replacement facilities for our leased facilities.

| Item 3. | Legal Proceedings

We are, from time-to-time, party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contract and/or property damages, punitive damages, civil and criminal penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, we record reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We do not believe that any of these proceedings, separately or in the aggregate, would be expected to have a material adverse effect on our financial position, results of operations, or cash flows.

We are routinely subject to other civil claims, litigation and arbitration, and regulatory investigations arising in the ordinary course of our past and present businesses as well as in respect of our divested businesses. Some of these include claims related to our services and operations, and asbestos-related claims concerning operations of a divested subsidiary of our predecessor. We believe that we have strong defenses to these claims as well as insurance coverage that will contribute to any settlement or liability in the event any asbestos-related claim is not resolved in our favor. These claims have not had a material impact on us to date, and we believe the likelihood that a future material adverse outcome will result from these claims is remote. However, if facts and circumstances change in the future, we cannot be certain that an adverse outcome of one or more of these claims would not have a material adverse effect on our financial condition, results of operations, or cash flows.

In January 2013, L. E. Myers was joined as a defendant in Northern States Power Company (Wisconsin) v. The City of Ashland, Wisconsin et al., filed in the U.S. District Court for the Western District of Wisconsin. Northern States Power Company alleged that named defendants, including L. E. Myers, contributed to contamination at the Ashland Lakefront Superfund Site in Ashland, Wisconsin. Specifically, the lawsuit alleged that L. E. Myers operated a manufactured gas plant at the site for 6 to 12 years of the plant’s operation during the time frame from 1885 to 1947. In April 2015, L. E. Myers negotiated a settlement of this litigation with Northern States Power Company, funded largely by L. E. Myers’ insurance carriers, with L. E. Myers’ contribution being $230,000.

#### Performance Graph

The following Performance Graph and related information shall be deemed “furnished” and not “filed” for purposes of Section 18 of the Exchange Act, and such information shall not be incorporated by reference into any future filing under the Securities Act or the Exchange Act except to the extent that we specifically incorporate it by reference into such filing.

The following graph compares, for the period from December 31, 2010 to December 31, 2015, the cumulative total stockholder return on our common stock with the cumulative total return on the Standard & Poor’s 500 Index (the “S&P 500 Index”), the Russell 2000 Index, and a peer group index selected by our management that includes fourteen publicly traded companies within our industry (the “Peer Group”). The comparison assumes that $100 was invested on December 31, 2010 and further assumes any dividends were reinvested quarterly. The stock price performance reflected on the following graph is not necessarily indicative of future stock price performance.

The companies in the Peer Group were selected because they comprise a broad group of publicly traded companies, each of which has some operations similar to ours. When taken as a whole, the Peer Group more closely resembles our total business than any individual company in the group while reducing the impact of a significant change in any one of the Peer Group company’s stock price. The Peer Group is composed of the following companies:

Aegion Corporation |  | Granite Construction Incorporated |  | Quanta Services, Inc.*
Astec Industries, Inc. |  | Integrated Electrical Services, Inc. |  | Tetra Tech, Inc.
Comfort Systems USA, Inc. |  | MasTec, Inc.* |  | TRC Companies, Inc.
Dycom Industries, Inc. |  | Matrix Service Company |  | Willbros Group, Inc.*
EMCOR Group* |  | Primoris Services Corporation |  |

| * | Considered our core group of peers with a more significant portion of operations being similar to ours than the overall group. Graph presents entire Peer Group.

| (1) | Working capital represents total current assets less total current liabilities.

| (2) | EBITDA, a performance measure used by management, is defined as net income (loss) plus: interest income and expense, provision (benefit) for income taxes and depreciation and amortization, as shown in the table below. EBITDA, a non-GAAP financial measure, does not purport to be an alternative to net income as a measure of operating performance or to net cash flows provided by operating activities as a measure of liquidity. Because not all companies use identical calculations, this presentation of EBITDA may not be comparable to other similarly-titled measures of other companies. We use, and we believe investors benefit from the presentation of, EBITDA in evaluating our operating performance because it provides us and our investors with an additional tool to compare our operating performance on a consistent basis by removing the impact of certain items that management believes do not directly reflect our core operations. We believe that EBITDA is useful to investors and other external users of our financial statements in evaluating our operating performance and cash flow because EBITDA is widely used by investors to measure a company’s operating performance without regard to items such as interest expense, taxes, depreciation and amortization, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired.

Using EBITDA as a performance measure has material limitations as compared to net income, or other financial measures as defined under U.S. GAAP as it excludes certain recurring items which may be meaningful to investors. EBITDA excludes interest expense or interest income; however, as we have borrowed money in order to finance transactions and operations, or invested available cash to generate interest income, interest expense and interest income are elements of our cost structure and can affect our ability to generate revenue and returns for our stockholders. Further, EBITDA excludes depreciation and amortization; however, as we use capital and intangible assets to generate revenues, depreciation and amortization are a necessary element of our costs and ability to generate revenue. Finally, EBITDA excludes income taxes; however, as we are organized as a corporation, the payment of taxes is a necessary element of our operations. As a result of these exclusions from EBITDA, any measure that excludes interest expense, interest income, depreciation and amortization and income taxes has material limitations as compared to net income. When using EBITDA as a performance measure, management compensates for these limitations by comparing EBITDA to net income in each period, so as to allow for the comparison of the performance of the underlying core operations with the overall performance of the

company on a full-cost, after-tax basis. Using both EBITDA and net income to evaluate the business allows management and investors to (a) assess our relative performance against our competitors and (b) monitor our capacity to generate returns for our stockholders. The following table provides a reconciliation of net income to EBITDA:

|  | For the year ended December 31,
(in thousands) |  | 2015 |  | 2014 |  | 2013 |  | 2012 |  | 2011

We also use EBITDA as a liquidity measure. We believe that EBITDA is important in analyzing our liquidity because it is a key component of certain material covenants (interest coverage ratio and leverage ratio) contained within our credit facility. Noncompliance with these financial covenants under our credit facility could result in our lenders requiring us to immediately repay all amounts borrowed. If we anticipated a potential covenant violation, we would seek relief from our lenders, which may cause us to incur additional cost, and such relief might not be available, or if available, might not be on terms as favorable as those in our credit facility. In addition, if we cannot satisfy these financial covenants, we would be prohibited under our credit facility from engaging in certain activities, such as incurring additional indebtedness, making certain payments, and acquiring or disposing of assets. Based on the information above, management believes that the presentation of EBITDA as a liquidity measure would be useful to investors and relevant to their assessment of our capacity to service, or incur, debt.

# MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussions should be read in conjunction with the other sections of this report, including the Financial Statements and related notes contained in Item 8 of this annual report on Form 10-K. In addition to historical information, this discussion contains forward-looking statements that involve risks, uncertainties and assumptions that could cause actual results to differ materially from management’s expectations. Factors that could cause such differences are discussed in “Forward-Looking Statements” and “Risk Factors.” We assume no obligation to update any of these forward-looking statements.

## Overview — Introduction

We are a leading specialty contractor serving the electrical infrastructure market. We manage and report our operations through two industry segments: T&D and C&I. We have operated in the T&D industry since 1891. We are one of the largest contractors servicing the T&D sector of the electric utility industry in the United States, and our customers include many of the leading companies in the industry. We have provided C&I electrical contracting services to facility owners and general contractors in the western United States since 1912. On April 13, 2015, we acquired substantially all the assets of ESB, which enhanced our T&D presence in the northeast U.S. and expanded our C&I presence outside of our existing markets. On November 24, 2015 we acquired all of the common stock of HCL, which added to our T&D capacity, predominantly in the western United States. In the second quarter of 2015 we were awarded our first project in Canada and have commenced work on this project in Manitoba as well as on several smaller projects in Canada.

We believe that we have a number of competitive advantages in both of our segments, including our skilled workforce, extensive centralized fleet, proven safety performance and reputation for timely completion of quality work that allow us to compete favorably in our markets. In addition, we believe that we are better capitalized than some of our competitors, which provides us with valuable flexibility to take on additional and complex projects.

We had revenues, for the year ended December 31, 2015, of $1.062 billion compared to $944.0 million for the year ended December 31, 2014. For the year ended December 31, 2015, our net income was $27.3 million compared to $36.5 million for the year ended December 31, 2014. While benefiting from increased spending by our customers in 2015, our project mix shifted away from large, multi-year transmission projects and included more shorter-duration projects. Shorter duration jobs often negatively affect gross margin and net income due to fleet utilization issues, labor productivity and mobilization and demobilization costs. In addition, increased competition in many of our markets resulted in lower bid margins, causing lower gross margins on those projects. The year ended December 31, 2014 benefited from unusually high gross margins that were primarily the result of favorable closeouts on several large, multi-year transmission projects, including several large claims or change orders.

## Overview — Segments

Transmission and Distribution segment. Our T&D segment provides comprehensive solutions to customers in the electric utility industry and the renewable energy industry. Our T&D segment generally serves the electric utility industry as a prime contractor to customers such as investor-owned utilities, cooperatives, private developers, government-funded utilities, independent power producers, independent transmission companies, industrial facility owners and other contractors. Our T&D segment provides a broad range of services on electric transmission and distribution networks and substation facilities which include design, engineering, procurement, construction, upgrade, maintenance and repair services with a particular focus on construction, maintenance and repair. The demand for transmission construction and maintenance services increased over the past several years due to the modernization of the existing electric utility infrastructure and the need to integrate renewable generation into the electric power grid.

30

TABLE OF CONTENTS

For the year ended December 31, 2015, our T&D revenues were $794.9 million or 74.9% of our revenue, compared to $699.6 million or 74.1% of our revenue for the year ended December 31, 2014 and $722.4 million or 80.0% of our revenue for the year ended December 31, 2013. Revenues from transmission projects represented 73.9%, 77.8% and 84.8% of T&D segment revenue for the years ended December 31, 2015, 2014 and 2013, respectively.

Our T&D segment also provides storm restoration services in response to hurricanes, ice or other storm related events, which typically account for less than 5% of our annual revenues. In 2015, 2014 and 2013, we recognized revenues from storm restoration services of approximately $7.7 million, $13.3 million and $14.6 million, respectively, which represented approximately 0.7%, 1.4% and 1.6% of our annual revenues, respectively.

Measured by revenues in our T&D segment, we provided 48.4%, 53.1% and 55.4% of our T&D services under fixed-price contracts during the years ended December 31, 2015, 2014 and 2013, respectively. We also provide many services to our customers under multi-year maintenance service agreements and other variable service agreements.

Commercial and Industrial segment. Our C&I segment provides services such as the design, installation, maintenance and repair of commercial and industrial wiring, installation of traffic networks and the installation of bridge, roadway and tunnel lighting. In our C&I segment, we generally provide our electric construction and maintenance services as a subcontractor to general contractors in the C&I industry as well as to facility owners. Our C&I operations are primarily in the western and northeastern United States where we have sufficient scale to deploy the level of resources necessary to achieve significant market share. We concentrate our efforts on projects where our technical and project management expertise are critical to successful and timely execution. The majority of C&I contracts cover electrical contracting services for airports, hospitals, data centers, hotels, stadiums, convention centers, manufacturing plants, processing facilities, waste-water treatment facilities, mining facilities and transportation control and management systems.

For the year ended December 31, 2015, our C&I revenues were $266.8 million or 25.1% of our revenue, compared to $244.4 million or 25.9% of our revenue for the year ended December 31, 2014 and $180.3 million or 20.0% of our revenue for the year ended December 31, 2013.

Measured by revenues in our C&I segment, we provided 71.6%, 41.7% and 45.9% of our services under fixed-price contracts for the years ended December 31, 2015, 2014 and 2013, respectively.

## Overview — Revenue and Gross Margins

Revenue Recognition. We recognize revenue on a percentage-of-completion method of accounting, which is commonly used in the construction industry. The percentage-of-completion accounting method results in recognizing contract revenues and earnings ratably over the contract term in proportion to our incurrence of contract costs (excluding uninstalled direct materials). The profits or losses recognized on individual contracts are based on estimates of contract revenues, costs and profitability. Contract losses are recognized in full when determined, and contract profit estimates are adjusted based on ongoing reviews of contract profitability. Changes in job performance, labor costs, equipment costs, job conditions, weather, estimated profitability and final contract settlements may result in revisions to costs and income and their effects are recognized in the period in which the revisions are determined. We record adjustments to estimated costs of contracts when we believe the change in estimate is probable and the amounts can be reasonably estimated. These adjustments could result in either increases or decreases in profit margins. The gross margins we record in the current period may not be indicative of margins in future periods.

Gross Margins. Our gross margin can vary between periods as a result of many factors, some of which are beyond our control. These factors include: the mix of revenue derived from the industries we serve, the size and duration of our projects, the mix of business conducted in different parts of the country, the mix in service and maintenance work compared to new construction work, the amount of work that we subcontract, the amount of material we supply, changes in labor, equipment or insurance costs, seasonal weather patterns, changes in fleet utilization, pricing pressures due to competition, efficiency of work performance, fluctuations in commodity prices of materials, delays in the timing of projects and other factors.

TABLE OF CONTENTS

## Overview — Economic, Industry and Market Factors

We operate in competitive markets, which can result in pricing pressures for the services we provide. Work is often awarded through a bidding and selection process, where price is always a principal factor. We generally focus on managing our profitability by: selecting projects that we believe will provide attractive margins; actively monitoring the costs of completing our projects; holding customers accountable for costs related to changes to contract specifications; and rewarding our employees for controlling costs.

The demand for construction and maintenance services from our customers has been, and will likely continue to be, cyclical in nature and vulnerable to downturns in the markets we serve as well as the economy in general. The financial condition of our customers and their access to capital, variations in the margins of projects performed during any particular period, and regional and national economic conditions may materially affect results. Project schedules, particularly in connection with larger, multi-year projects, can also create fluctuations in our revenues. Other market and industry factors, such as changes to our customers’ capital spending plans or delays in regulatory approvals can affect project schedules. Changes in technology, tax and other incentives and new or changing regulatory requirements affecting the industries we serve can impact demand for our services. While we actively monitor economic, industry and market factors affecting our business, we cannot predict the impact such factors may have on our future results of operations, liquidity and cash flows. As a result of economic, industry and market factors, our operating results in any particular period or year may not be indicative of the results that can be expected for any other period or for any other year.

## Overview — Seasonality

Although our revenues are primarily driven by spending patterns in our customers’ industries, our revenues, particularly those derived from our T&D segment, and results of operations can be subject to seasonal variations. These variations are influenced by weather, daylight hours, availability of system outages from utilities, and holidays. During the winter months, demand for our T&D work may be high, but our work can be delayed due to inclement weather. During the summer months, the demand for our T&D work may be affected by fewer available system outages during which we can perform electrical line service work due to peak electrical demands caused by warmer weather conditions. During the spring and fall months, the demand for our T&D work may increase due to improved weather conditions and system availability; however, extended periods of rain and other severe weather can affect the deployment of our crews and efficiency of operations.

We also provide storm restoration services to our T&D customers. These services tend to have a higher profit margin. However, storm restoration service work that is performed under an MSA typically has similar rates to other work under the agreement. In addition, deploying employees on storm restoration work may, at times, delay work on other transmission and distribution work. Storm restoration service work is unpredictable and can affect results of operations.

## Outlook

In the last few years we benefited from increased activity and spending in the electrical transmission markets we serve. We continue to expect long-term growth in the transmission market, although the timing of large bids and subsequent construction is likely to be highly variable from year to year. We believe several multi-year transmission projects will be available for bid in the 2016 to 2017 timeframe. We also expect bidding activity in small- to medium-sized transmission and distribution projects to continue in 2016 In 2015, we expanded our T&D presence organically through establishing new or additional operating locations in California, Kansas, Texas and Canada; and with the acquisitions of ESB and HCL. We also started work on our first project in Canada. In 2015, we expanded our C&I presence into the northeast with the acquisition of ESB, further increased our C&I business through organic growth in our existing markets and expanded geographically into Oregon, Minnesota and Washington. We believe that legislative and regulatory actions, state renewable portfolio standards, the aging of the electric grid, and the general improvement of the economy will positively impact the level of spending by our customers. Although competition remains strong, we see these trends as positive factors for us in the future.

32

TABLE OF CONTENTS

Our business is directly impacted by the level of spending on T&D infrastructure across the U.S. and Canada and the level of commercial and industrial electrical construction activity in the markets we serve. The electric grid is aging and requires significant upgrades and maintenance to meet current and future demands for electricity. In addition, regulatory pressures and low energy prices may accelerate the shut-down of coal-fired generating plants, which could result in the need for line upgrades and new substations. Over the past several years, many utilities have begun to implement plans to improve their transmission systems, improve reliability and reduce congestion. These utilities have started or planned new construction, line upgrades and maintenance projects on many transmission systems. We believe that our customers remain committed to the expansion and strengthening of their transmission infrastructure, with planning, engineering and funding for many of their projects already in place.

We believe we will continue to see significant bidding activity on large transmission projects in 2016 and 2017. The timing of multi-year transmission project awards and substantial construction activity is difficult to predict due to regulatory requirements and right-of-way permits needed to commence construction. Significant construction on any large, multi-year projects awarded in 2016 will not likely occur until 2017. Bidding and construction activity for small to medium-size transmission projects and upgrades remains strong, and we expect this trend to continue in 2016, primarily due to reliability and economic drivers. Competition in the transmission market continues to make winning projects difficult and has increased pressure on contract margins.

We continue to see opportunities in the Canadian transmission market which we expect will extend over the next several years driven by load center delivery requirements, aging infrastructure, additional hydropower generation development and hydropower interconnection projects to serve Canadian load and the import of hydro power to the U.S. In 2015, our efforts to expand our service offerings within Canada resulted in the award of a large switchyard related to the Bipole III initiative in Manitoba, and we are evaluating several near- and long-term Canadian projects and opportunities that we believe would fit our portfolio of work.

Legislative or regulatory actions may affect demand for the services provided by our T&D segment in the long term, particularly in connection with electric power infrastructure. Federal Energy Regulatory Commission (FERC) Order No. 1000 promotes more efficient and cost-effective development of new transmission facilities, which we believe could have a long-term positive impact on electric transmission line development. We also anticipate increased infrastructure spending over the long term as a result of legislation requiring the electric power industry to meet national and local reliability standards for its transmission and distribution systems and incentives to the industry to invest in and improve maintenance on its systems. The U.S. Environmental Protection Agency’s Mercury and Air Toxics Standards (“MATS”) may force retirement of some coal-fired and oil-fired generating plants in the U.S. This compliance planning and implementation could result in increased spending by the affected utilities to strengthen their transmission infrastructure to alleviate congestion and deliver new and existing power sources to their regions.

We believe that renewable resources in the U.S. will be a driver for large transmission project activity. State renewable portfolio standards, which set required or voluntary standards for how much electricity is to be generated from renewable energy sources, as well as general environmental concerns, are driving the development of renewable energy projects. The economic feasibility of renewable energy projects, and therefore the attractiveness of investment in the projects, may depend on the availability of tax incentive programs or the ability of the projects to take advantage of such incentives. The late-2015 congressional approval of a five-year extension to the Production Tax Credit and Investment Tax Credit should help spur additional wind and solar development, and we believe we will benefit from an increase in these projects.

As a result of reduced spending by U.S. utilities on their distribution systems for several years, we believe there is a growing need for sustained investment by utilities on their distribution systems to properly maintain or meet reliability requirements. In 2015 we saw increased bidding activity in some of our electric distribution markets, as economic conditions improved in those areas. We believe that a recovery in the U.S. economy, and in the housing market in particular, over the next few years could provide additional stimulus for spending by our customers on their distribution systems. In addition, we believe there will be a push to strengthen utility distribution systems against major storm-related damage. Several industry and market trends are also prompting customers in the electric utility industry to seek outsourcing partners rather

33

TABLE OF CONTENTS

than performing projects internally. These trends include an aging electric utility workforce, increasing costs and labor issues. We believe electric utility employee retirements could increase with further economic recovery, which may result in an increase in outsourcing opportunities. We expect to see an incremental increase in distribution opportunities in the U.S. in 2016 and we believe these opportunities will continue to be bid in a competitive market.

We saw increased activity in many of our C&I markets in 2015. Results in our C&I segment improved significantly over the prior year as economic conditions improved. We expect to see continued improvement in both bidding opportunities and margins in our C&I segment in 2016. We expect the long-term growth in our C&I segment to generally track the economic growth of the regions we serve and benefit to the extent economic conditions continue to improve in the markets we serve. In the event economic conditions in these regions continue to improve, we ecpect our operations will benefit.

We continue to invest in developing key management and craft personnel in both our T&D and C&I markets and in procuring the specialty equipment and tooling needed to win and execute projects of all sizes and complexity. In 2015 and 2014, we invested in capital expenditures of approximately $46.6 million and $39.0 million, respectively. Most of our capital expenditures supported opportunities in our T&D business. We plan to continue to invest in additional equipment and tooling, substantially through cash flows from operations and cash on hand, with a focus on transmission and distribution but we expect our capital expenditures in 2016 will be reduced from our 2015 capital expenditures as we look to expand our fleet through alternative financing approaches such as leasing. For some years we have been entering into operating leases for some of our facility, vehicle and equipment needs. These leases allow us to conserve cash by paying a monthly lease rental fee for the use of facilities, vehicles and equipment rather than purchasing them. We intend to increase our use of leasing arrangements in 2016, particularly for the acquisition of shorter-lived assets, but will continue to purchase specialty equipment, which provides us with valuable flexibility to take on additional and complex projects.

Our investment strategy is based on our belief that spending in transmission and distribution projects will continue to remain strong over the next several years as electric utilities, cooperatives and municipalities make up for the lack of infrastructure spending in the past, combined with the overall need to integrate new generation into the electric power grid, and our belief that distribution demand will increase over the next several years.

Our future growth may be organic or through strategic acquisitions or joint ventures that we expect will improve our competitive position within our existing markets or expand our geographic footprint. We ended 2015 in a strong financial position, which included cash and cash equivalents of $39.8 million and availability of $155.7 million under our credit facility. We believe that our financial and operational strengths will enable us to manage the current challenges and uncertainties in the markets we serve and give us the flexibility for further strategic investments.

## Understanding Backlog

We define backlog as our estimated revenue on uncompleted contracts, including the amount of revenue on contracts for which work has not begun, less the revenue we have recognized under such contracts. Backlog may not accurately represent the revenues that we expect to realize during any particular period. Several factors, such as the timing of contract awards, the type and duration of contracts, and the mix of subcontractor and material costs in our projects, can impact our backlog at any point in time. Some of our revenue does not appear in our periodic backlog reporting because the award of the project, as well as the execution of the work, can all take place within the period. For many of our unit-price, time-and-equipment, time-and-materials and cost-plus contracts, we only include projected revenue for a three-month period in the calculation of backlog, although these types of contracts are generally awarded as part of MSAs that typically have a one-year to three-year duration from execution. Our backlog only includes projects that have a signed contract or an agreed upon work order to perform work on mutually accepted terms and conditions.

Changes in backlog from period to period are primarily the result of fluctuations in the timing of awards and revenue recognition of contracts.

## Understanding Gross Margins

Our gross margin is gross profit expressed as a percentage of revenues. Gross profit is calculated by subtracting contract costs from revenue. Contract costs consist primarily of salaries, wages and benefits to employees, depreciation, fuel and other equipment expenses, equipment rentals, subcontracted services, insurance, facilities expenses, materials and parts and supplies. Various factors affect our gross margins on a quarterly or annual basis, including those listed below.

Performance Risk. Margins may fluctuate because of the volume of work and the impacts of pricing and job productivity, which can be impacted both favorably and negatively by customer decisions and crew productivity, as well as other factors. When comparing a service contract between periods, factors affecting the gross margins associated with the revenues generated by the contract may include pricing under the contract, the volume of work performed under the contract, the mix of the type of work specifically being performed, the availability of labor resources at expected labor rates and the productivity of the crews performing the work. Productivity can be influenced by many factors including the experience level of the crew, whether the work is on an open or encumbered right of way, weather conditions, geographical conditions and effects of environmental restrictions or regulatory delays.

Seasonal, Weather and Geographical. Seasonal patterns, primarily related to weather conditions and the availability of system outages, can have a significant impact on gross margins in a given period. It is typical during the winter months that parts of the country may experience snow or rainfall, which can affect our crews’ ability to work efficiently. Additionally, our T&D customers often cannot remove their T&D lines from service during the summer months, when consumer demand for electricity is at its peak, delaying the demand for our maintenance and repair services. In both cases, projects may be delayed or temporarily placed on hold. Conversely, in periods when weather remains dry and temperatures are moderate, more work can be done, sometimes with less cost, which would have a favorable impact on gross margins. The mix of business conducted in different parts of the country will also affect margins, as some parts of the country offer the opportunity for higher margins than others due to the geographic characteristics associated with the physical location where the work is being performed. Such characteristics include whether the project is performed in an urban versus a rural setting; in a mountainous area or in open terrain; or in normal soil conditions or rocky terrain. Site conditions, including unforeseen underground conditions, can also impact margins.

Depreciation and Amortization. We include depreciation on equipment in contract costs. This is common practice in our industry, but can make comparability to other companies difficult. Over the last few years, we have spent a significant amount of capital on property, facilities and equipment, with the majority of such expenditures being used to purchase additional specialized equipment to enhance our fleet and to reduce our reliance on lease arrangements and short term equipment rentals. In 2016 we intend to redeploy our capital by purchasing less equipment and increasing the use of alternative financing approaches, such as leasing, to meet our capital needs. We believe the investment in specialized equipment helps to reduce our costs and improve our margins and provides us with valuable flexibility to take on additional and complex projects. However, in 2016 we intend to procure more of our shorter-lived equipment through leasing arrangements, which will decrease our depreciation expense.

Revenue Mix. The mix of revenue derived from the industries we serve will impact gross margins. Changes in our customers’ spending patterns in each of the industries we serve can cause an imbalance in supply and demand and, therefore, affect margins and mix of revenue by industry served. Storm restoration services typically command higher profit margins than other maintenance services. Seasonal and weather factors, as noted above, can impact the timing at which customers perform maintenance and repairs, which can cause a shift in the revenue mix.

Service and Maintenance Compared to New Construction. In general, new construction work has a higher gross margin than maintenance and repair work. New construction work is often obtained on a fixed-price basis, which carries a higher risk than other types of pricing arrangements because a contractor can bear the risk of increased expenses. As such, we generally bid fixed-price contracts with higher profit margins. We typically derive approximately 10% to 35% of our revenue from maintenance and repair work that is performed under pre-established or negotiated prices or cost-plus pricing arrangements which generally allow

35

TABLE OF CONTENTS

us a set margin above our costs. Thus, the mix between new construction work, at fixed-price, and maintenance and repair work, at cost-plus, in a given period will impact gross margin in that period.

Material and Subcontract Costs. Projects that include a greater amount of material or subcontractor costs can experience lower overall project gross margins as we typically add less mark up to material and subcontractor costs in our bids than what we would to our labor and equipment cost. In addition, successful completion of our contracts may depend on whether our subcontractors successfully fulfill their contractual obligations. If our subcontractors fail to satisfactorily perform their contractual obligations as a result of financial or other difficulties, we may be required to incur additional costs and provide additional services in order to make up such shortfalls.

Cost of Material. On fixed-price contracts where we are required to provide materials, our overall gross margin may be affected if we experience increases in material quantity or higher commodity costs.

Materials versus Labor. Projects that include a greater amount of material cost can experience lower overall project gross margins as we typically add less mark up to material cost in our bids than what we would to our labor and equipment cost.

Insurance. Gross margins could be impacted by fluctuations in insurance accruals related to our deductibles in the period in which such adjustments are made. We carry insurance policies, which were subject to certain deductibles, for workers’ compensation, general liability, automobile liability and other coverages. Losses up to the deductible amounts are accrued based upon estimates of the ultimate liability for claims reported and an estimate of claims incurred but not yet reported.

Fleet Utilization, Estimation, and Bidding. We operate a centrally-managed fleet in an effort to achieve the highest equipment utilization. We also develop internal equipment rates which provide our business units with appropriate cost information to estimate bids for new projects. Availability of equipment for a particular contract is determined by our internal fleet ordering process which is designed to optimize the use of internal fleet assets and allocate equipment costs to individual contracts. We believe these processes allow us to utilize our equipment efficiently, which leads to improved gross margins.

Our team of trained estimators helps us to determine potential costs and revenues and make informed decisions on whether to bid for a project and, if bid, the rates to use in estimating the costs for that bid. The ability to accurately estimate labor, equipment, subcontracting and material costs in connection with a new project may affect the gross margins achieved for the project.

## Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of compensation, related benefits and employee costs for management and administrative personnel, office rent and utilities, stock compensation, communications, professional fees, depreciation, marketing costs and bad debt expense.

## Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014

Revenues. Revenues increased $117.7 million, or 12.5%, to $1.062 billion for the year ended December 31, 2015 from $944.0 million for the year ended December 31, 2014. The increase was primarily due to higher T&D revenues and the acquisition of ESB. We benefited from increased spending by our customers and organic growth from new geographic markets, however, our project mix of shorter-duration projects increased while the number of large, multi-year transmission projects declined.

Gross margin. Gross margin decreased to 11.5% for the year ended December 31, 2015 from 14.0% for the year ended December 31, 2014. Gross margin in 2014 benefited from favorable closeouts on several large, multi-year transmission projects. The remaining year-over-year decline in gross margin was primarily due to lower bid margins caused by increased competition in many of our markets and an increase in the number of shorter duration projects (which affects fleet utilization, labor productivity and mobilization and demobilization costs). Additionally, some of our jobs underperformed in 2015 due to labor productivity below previous estimates as a result of excessive labor turnover, rework on certain jobs and severe weather conditions in some of our markets. Changes in estimates of gross profit on certain projects resulted in gross margin increases of 0.5% for the year ended December 31, 2015. Changes in estimates of gross profit on certain projects, including several large claims or change orders, resulted in gross margin increases of 1.9% for the year ended December 31, 2014.

Gross profit. Gross profit decreased $10.1 million, or 7.6%, to $122.3 million for year ended December 31, 2015 from $132.4 million for the year ended December 31, 2014, primarily due to lower gross margin partially offset by higher revenues.

Selling, general and administrative expenses. Selling, general and administrative expenses, which were $79.2 million for the year ended December 31, 2015, increased $5.4 million from $73.8 million for the year ended December 31, 2014. The increase in selling, general and administrative expenses for the year ended December 31, 2015 as compared to the year ended December 31, 2014 was primarily due to higher personnel

37

TABLE OF CONTENTS

and overhead costs to support our organic and acquisitive geographic market expansion, the impact of reversing a $2.3 million legal reserve in the fourth quarter in 2014, $1.4 million related to an executive officer transition and costs associated with the ESB and HCL acquisitions, partially offset by lower bonus and profit sharing costs. As a percentage of revenues, selling, general and administrative expenses decreased to 7.5% for the year ended December 31, 2015 from 7.8% for the year ended December 31, 2014.

Gain on sale of property and equipment. Gains from the sale of property and equipment in the year ended December 31, 2015 were $2.3 million compared to $0.1 million in the year ended December 31, 2014. Gains from the sale of property and equipment are attributable to routine sales of property and equipment no longer useful or valuable to our ongoing operations.

Interest expense. Interest expense was $0.7 million for both of the years ended December 31, 2015 and 2014.

Income tax expense. The provision for income taxes was $17.0 million for the year ended December 31, 2015, with an effective tax rate of 38.4%, compared to a provision of $21.4 million for the year ended December 31, 2014, with an effective tax rate of 36.9%. The increase in the effective rate was primarily caused by changes in the mix of business between states and the impact of the foreign tax differential.

Net income. Net income decreased to $27.3 million for the year ended December 31, 2015 from $36.5 million for the year ended December 31, 2014. The decrease was primarily for the reasons stated above.

#### Transmission & Distribution

Revenues for our T&D segment for the year ended December 31, 2015 were $794.9 million compared to $699.6 million for the year ended December 31, 2014, an increase of $95.3 million or 13.6%. While we benefited from increased spending by our customers, our project mix shifted away from large, multi-year transmission projects and included more shorter-duration projects.

Revenues from transmission projects represented 73.9% and 77.8% of T&D segment revenue for the years ended December 31, 2015 and 2014, respectively. Additionally, for the year ended December 31, 2015, measured by revenue in our T&D segment, we provided 48.4% of our T&D services under fixed-price contracts, as compared to 53.1% for the year ended December 31, 2014.

Operating income for our T&D segment for the year ended December 31, 2015 was $63.1 million compared to $75.4 million for the year ended December 31, 2014. Operating income in 2014 benefited from large, multi-year transmission projects. The remaining year-over-year decline in operating income was primarily due to lower bid margins caused by increased competition in many of our markets and an increase

38

TABLE OF CONTENTS

in the number of shorter duration projects (which affects fleet utilization, labor productivity and mobilization and demobilization costs). Additionally, some of our jobs underperformed in 2015 due to labor productivity below previous estimates, incremental costs associated with expansion into new geographic markets and severe weather conditions in some of our markets, partially offset by higher revenues. Operating income, as a percentage of revenues, for our T&D segment decreased to 7.9% for the year ended December 31, 2015 from 10.8% for the year ended December 31, 2014.

#### Commercial & Industrial

Revenues for our C&I segment for the year ended December 31, 2015 were $266.8 million compared to $244.4 million for the year ended December 31, 2014, an increase of $22.4 million or 9.2%, due primarily to the acquisition of ESB. For the year ended December 31, 2015, measured by revenue in our C&I segment, we provided 71.6% of our services under fixed-price contracts, as compared to 41.7% for the year ended December 31, 2014.

Operating income for our C&I segment for the year ended December 31, 2015 was $13.6 million compared to $16.5 million for the year ended December 31, 2014, a decrease of $2.9 million, or 17.6%. The year-over-year decline in operating income compared to the year ended December 31, 2014 was primarily due to lower bid margins caused by increased competition in many of our markets and certain underperforming jobs due to labor productivity below previous estimates as a result of excessive labor turnover and rework and incremental costs associated with expansion into new geographic markets, partially offset by higher revenues. As a percentage of revenues, operating income for our C&I segment decreased to 5.1% for the year ended December 31, 2015 from 6.8% for the year ended December 31, 2014.

#### Corporate

The decrease in corporate expenses in 2015 was primarily attributable to lower bonus and profit sharing costs.

## Year Ended December 31, 2014 Compared to the Year Ended December 31, 2013

Revenues. Revenues increased $41.3 million, or 4.6%, to $944.0 million for the year ended December 31, 2014 from $902.7 million for the year ended December 31, 2013 due to higher C&I revenues, partially offset by lower transmission revenues. Material and subcontractor cost comprised approximately 33% of total contract cost in the year ended December 31, 2014, compared to approximately 31% in the year ended December 31, 2013.

Gross profit. Gross profit increased $7.5 million, or 6.0%, to $132.4 million for the year ended December 31, 2014 from $124.9 million for the year ended December 31, 2013. Gross margin increased to 14.0% in the year ended December 31, 2014 from 13.8% in the year ended December 31, 2013. Gross margins in 2014 and 2013 included net benefits of approximately 1.9% and 0.8%, respectively, from improved contract margins on several transmission projects due to change orders, resolution of claims, cost efficiencies, additional work and effective contract management. The gross margin benefit in 2014 was partially offset by lower equipment utilization, particularly large specialty transmission equipment as several large transmission projects were nearing completion, and higher equipment repair and maintenance costs.

Selling, general and administrative expenses. Selling, general and administrative expenses increased approximately $4.0 million, or 5.7%, to $73.8 million for the year ended December 31, 2014 from $69.8 million for the year ended December 31, 2013 primarily due to an increase in employee compensation and fringe benefits related to the increased number of personnel assigned to support operations and higher profit sharing and stock compensation costs. In the third quarter of 2013, we recorded a $2.3 million legal reserve which represented estimated punitive damages, interest and cost of an appeal bond pertaining to an adverse judgment involving a traffic accident in Florida. On February 27, 2015, a Florida appeals court unanimously reversed this judgment, determined that punitive damages were not available and remanded the case for a new trial. As a result, the $2.3 million legal reserve was reversed in the fourth quarter of 2014. As a percentage of revenues, selling, general and administrative expenses increased to 7.8% for the year ended December 31, 2014 from 7.7% for the year ended December 31, 2013.

Gain on sale of property and equipment. Gains from the sale of property and equipment decreased $0.8 million to $0.1 million for the year ended December 31, 2014 from $0.9 million for the year ended

39

TABLE OF CONTENTS

December 31, 2013. Gains from the sale of property and equipment are the result of routine sales of property and equipment that are no longer useful or valuable to our ongoing operations.

Interest expense. Interest expense was $0.7 million for both the years ended December 31, 2014 and 2013.

Income tax expense. The provision for income taxes was $21.4 million for the year ended December 31, 2014, with an effective tax rate of 36.9%, compared to a provision of $20.1 million for the year ended December 31, 2013, with an effective tax rate of 36.7%.

Net income. Net income in 2014 increased to $36.5 million for the year ended December 31, 2014 from $34.8 million for the year ended December 31, 2013 for the reasons stated above.

#### Transmission & Distribution

Revenues for our T&D segment for the year ended December 31, 2014 were $699.6 million compared to $722.4 million for the year ended December 31, 2013, a decrease of $22.8 million or 3.2%. The decline in revenue was primarily due to lower revenues on several large transmission projects that were substantially complete or nearing completion, which were partially offset by higher distribution revenues. Material and subcontractor costs in our T&D segment comprised approximately 28% of total contract costs in the year ended December 31, 2014, compared to approximately 27% in the year ended December 31, 2013.

Revenues from transmission projects represented 77.8% and 84.8% of T&D segment revenue for the years ended December 31, 2014 and 2013, respectively. Additionally, for the year ended December 31, 2014, measured by revenue in our T&D segment, we provided 53.1% of our T&D services under fixed-price contracts, as compared to 55.4% for the year ended December 31, 2013.

Operating income for our T&D segment for the year ended December 31, 2014 was $75.4 million compared to $81.4 million for the year ended December 31, 2013 primarily due to lower equipment utilization, particularly large specialty transmission equipment as several large transmission projects were nearing completion, as well as higher equipment repair and maintenance costs. The impact of lower equipment utilization was partially offset by improved contract margins on several transmission projects due to change orders, resolution of claims, cost efficiencies, additional work and effective contract management. Operating income, as a percentage of revenues, for our T&D segment decreased to 10.8% for the year ended December 31, 2014 from 11.3% for the year ended December 31, 2013.

#### Commercial & Industrial

Revenues for our C&I segment for the year ended December 31, 2014 were $244.4 million compared to $180.3 million for the year ended December 31, 2013, an increase of $64.1 million or 35.5%. The increase in revenues was largely due to increased activity in most of our service offerings as well as improved market conditions in Colorado and Arizona. Material and subcontractor cost in our C&I segment comprised approximately 48% of total contract cost in the year ended December 31, 2014, compared to approximately 44% in the year ended December 31, 2013.

For the year ended December 31, 2014, measured by revenue in our C&I segment, we provided 41.7% of our services under fixed-price contracts, as compared to 45.9% for the year ended December 31, 2013.

Operating income for our C&I segment for the year ended December 31, 2014 was $16.5 million compared to $10.4 million for the year ended December 31, 2013, an increase of $6.1 million, or 58.7%. As a percentage of revenues, operating income for our C&I segment increased to 6.8% for the year ended December 31, 2014 from 5.8% for the year ended December 31, 2013. The increase in operating income was primarily due to increased revenue compared to 2013 and improved efficiency on the jobs we performed in 2014.

#### Corporate

The decrease in corporate expenses in 2014 was primarily attributable to the reversal in the fourth quarter of 2014 of the $2.3 million legal reserve, which had been accrued in 2013. The year over year impact of the legal reserve was partially offset by increased employee compensation and fringe benefits related to the increased number of personnel assigned to support operations and higher profit sharing and stock compensation costs.

## Liquidity and Capital Resources

As of December 31, 2015, we had cash and cash equivalents of $39.8 million and working capital of $123.6 million. During the year ended December 31, 2015, consolidated operating activities of our business resulted in net cash flow from operations of $43.0 million compared to $55.0 million for the year ended December 31, 2014. The $12.0 million decline in cash provided by operating activities was primarily due to the $9.2 decline in net income. Cash flow from operations is primarily influenced by demand for our services, operating margins and the type of services we provide our customers. The changes in various working capital accounts (such as: accounts receivable, including retention; costs and estimated earnings in excess of billings on uncompleted contracts; accounts payable; and billings in excess of costs and estimated earnings on uncompleted contracts) are due to both the volume and timing of work performed, the mix of the types of projects and customers and their varying billing requirements as well as settlements of payables and other obligations. In particular, the gross amount of accounts receivable, net, costs and estimated earnings in excess of billings on uncompleted contracts, and billings in excess of costs and estimated earnings on uncompleted contracts used cash of $21.3 million in 2015, net of acquired balances, compared to $3.2 million of cash used in 2014, a year-over-year decline in cash used of $18.1 million.

Days sales outstanding (DSO) was 66.7 days as of December 31, 2015, as compared to 59.8 days at December 31, 2014. The increase of 6.9 days has an impact of approximately $20.3 million in increased working capital, unrelated to volume. This increase is primarily due to timing of collections on our accounts receivable for various projects due to resolution of change orders and project close outs as well as customer mix and size of projects. In addition, billings are impacted by new customer billing processes that require additional efforts to process invoices, as well as requirements under various contracts. DSO is calculated by using the sum of current accounts receivable, net of allowances, retention receivables plus costs and estimated earnings in excess of billings on uncompleted contracts less billing in excess of costs and estimated earnings on uncompleted contracts, divided by average revenues per day during the last quarter.

Accounts payable, which provided $6.7 million in cash in 2015 compared to using $17.3 million in 2014, accounted for a $24.0 million year-over-year change in cash used as a result of an increase in revenue volume and the timing of material purchases and subcontractor payments on contracts. Additionally, year-over-year changes in self-insurance reserves and other liabilities contributed to the year-over-year decline in cash provided by operating activities.

TABLE OF CONTENTS

During the years ended December 31, 2015 and 2014, we used net cash of $56.9 million and $38.7 million, respectively, in investing activities. The $56.9 million of cash used in investing activities in the year ended December 31, 2015 consisted of $46.6 million for capital expenditures and $13.1 million to acquire ESB and HCL, partially offset by $2.8 million of proceeds from the sale of equipment.

During the years ended December 31, 2015 and 2014, we used net cash of $23.9 million and $15.1 million, respectively, in financing activities. The $23.9 million of cash used in financing activities in the year ended December 31, 2015 consisted of $27.6 million of cash used to purchase shares of our common stock, which was partially offset by proceeds from stock options and tax benefits related to our stock compensation programs. The $27.6 million of cash used to purchase shares of our common stock consisted of $26.1 million purchased under our Repurchase Program and $1.5 million to purchase shares surrendered by employees to satisfy employee tax obligations under our stock compensation program. On July 30, 2015, our Board of Directors approved an amended Repurchase Program, which increased the program from $25.0 million to $42.5 million and extended the term of the program through August 31, 2016. On December 10, 2015, our Board of Directors approved an amended Repurchase Program, which increased the program from $42.5 million to $67.5 million. As of December 31, 2015, we had $24.8 million of remaining availability to purchase shares under the Repurchase Program. As of December 31, 2015, the Company has spent $42.7 million to repurchase 1,835,120 shares at an average repurchase price of $23.22 since the inception of this program.

We anticipate that our cash and cash equivalents on hand, borrowing capacity under our credit facility, and future cash flow from operations will provide sufficient cash to enable us to meet our future operating needs, debt service requirements, share repurchases and planned capital expenditures. We expect our capital expenditures in 2016 will be lower than the last few years as we look to expand our fleet through an increased use of alternative financing approaches, such as leasing. For some years we have been using operating leases for some of our facility, vehicle and equipment needs. These leases allow us to conserve cash by paying a monthly lease rental fee for the use of facilities, vehicles and equipment rather than purchasing them. We intend to increase our use of leasing arrangements in 2016, particularly for the acquisition of shorter-lived assets, but will continue to purchase specialty equipment, which provides us with valuable flexibility to take on additional and complex projects.

Although we believe that we have adequate cash and availability under our credit facility to meet our liquidity needs, our involvement in any multi-year transmission projects or the acquisition of other companies may require additional capital, depending upon the size of the project or the acquisition and the financial terms of the underlying agreement.

#### Share Repurchase Amendment

On February 10, 2016 the Board approved amendments to our Repurchase Program to increase the capacity by $75.0 million, modify its provisions to accelerate the pace of share repurchases, and extend the term through April 30, 2017. The amendments increased the overall size of the Repurchase Program to $142.5 million. The Company intends to fund the repurchase program from cash on hand and through borrowings under its credit facility.

#### Debt Instruments

On December 21, 2011, we entered into a five-year syndicated credit agreement (the “Credit Agreement”) for an initial facility of $175.0 million (the “Facility”). The entire Facility is available for revolving loans and the issuance of letters of credit. We have an option to increase the commitments under the Facility or enter into incremental term loans, subject to certain conditions, by up to an additional $75.0 million upon receipt of additional commitments from new or existing lenders. Up to $25.0 million of the Facility is available for swingline loans.

Revolving loans under the Facility bear interest, at our option, at either (1) ABR, which is the greatest of the Prime Rate, the Federal Funds Effective Rate plus 0.50% or adjusted LIBOR plus 1.00%, plus in each case an applicable margin ranging from 0.00% to 1.00%; or (2) adjusted LIBOR plus an applicable margin ranging from 1.00% to 2.00%. The applicable margin is determined based on our leverage ratio (the “Leverage Ratio”), defined under the Credit Agreement as consolidated total indebtedness divided by consolidated EBITDA as defined by the Credit Agreement (“Consolidated EBITDA”). Letters of credit issued

42

TABLE OF CONTENTS

under the Facility are subject to a letter of credit fee of 1.00% to 2.00%, based on our Leverage Ratio and a fronting fee of 0.125%. Swingline loans will bear interest at the ABR Rate. We are required to pay a 0.2% commitment fee on the unused portion of the Facility.

Subject to certain exceptions, the Facility is secured by substantially all of our assets and the assets of all of our subsidiaries and by a pledge of all of the capital stock of our subsidiaries. Our subsidiaries also guarantee the repayment of all amounts due under the Facility. The Credit Agreement provides for customary events of default. If an event of default occurs and is continuing, on the terms and subject to the conditions set forth in the Credit Agreement, amounts outstanding under the Facility may be accelerated and may become or be declared immediately due and payable.

Under the Credit Agreement, we are subject to certain financial covenants, a Leverage Ratio and an interest coverage ratio (“Interest Coverage Ratio”), defined under the Credit Agreement as Consolidated EBITDA divided by interest expense. The Credit Agreement also contains a number of covenants including limitations on asset sales, investments, indebtedness and liens. We were in compliance with all covenants at December 31, 2015.

As of December 31, 2015 and 2014, we had no debt outstanding, $155.7 million available for borrowing under our Credit Agreement and approximately $19.3 million in irrevocable standby letters of credit outstanding under our Credit Agreement at an interest rate of 1.125%. The Facility expires on December 21, 2016 and we anticipate that we will be able to renew the Facility before it expires, but we can give no assurance that we can do so on favorable terms, if at all.

## Off-Balance Sheet Arrangements

As is common in our industry, we enter into certain off-balance sheet arrangements in the ordinary course of business that result in risks not directly reflected in our balance sheets. Our significant off-balance sheet transactions include liabilities associated with non-cancelable operating leases, letter of credit obligations and bond guarantees entered into in the normal course of business. We have not engaged in any off-balance sheet financing arrangements through special purpose entities.

#### Leases

We enter into non-cancelable operating leases for some of our facility, vehicle and equipment needs. These leases allow us to conserve cash by paying a monthly lease rental fee for the use of facilities, vehicles and equipment rather than purchasing them. We may decide to cancel or terminate a lease before the end of its term, in which case we are typically liable to the lessor for the remaining lease payments under the term of the lease. At December 31, 2015, we had no leases with residual value guarantees.

We typically have purchase options on the equipment underlying our long-term operating leases and many of our short-term rental arrangements. We exercise some of these purchase options when the need for equipment is on-going and the purchase option price is attractive.

#### Purchase Commitments for Construction Equipment

As of December 31, 2015, we had approximately $2.2 million in outstanding purchase obligations for certain construction equipment to be paid, with most of the cash outlay scheduled to occur over the first three months of 2016.

#### Letters of Credit

Some of our vendors require letters of credit to ensure reimbursement for amounts they are disbursing on our behalf, such as to beneficiaries under our insurance programs. In addition, from time-to-time certain customers require us to post letters of credit to ensure payment to our subcontractors and vendors under those contracts and to guarantee performance under our contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit commits the issuer to pay specified amounts to the holder of the letter of credit if the holder claims that we have failed to perform specified actions in accordance with the terms of the letter of credit. If this were to occur, we would be required to reimburse the issuer of the letter of credit. Depending on the circumstances of such a reimbursement, we may also have to record a charge to earnings for the reimbursement. Currently, we do not believe that it is likely that any claims will be made under any letter of credit in the foreseeable future.

43

TABLE OF CONTENTS

At December 31, 2015, we had $19.3 million in irrevocable standby letters of credit outstanding under our Credit Agreement at an interest rate of 1.125%, including $17.5 million related to the Company’s payment obligation under its insurance programs and approximately $1.8 million related to contract performance obligations.

#### Performance and Payment Bonds

Many customers, particularly in connection with new construction, require us to post performance and payment bonds issued by a financial institution known as a surety. These bonds provide a guarantee to the customer that we will perform under the terms of a contract and that we will pay subcontractors and vendors. If we fail to perform under a 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 surety for any expenses or outlays it incurs. Under our continuing indemnity and security agreement with the surety, with the consent of our lenders under the Credit Agreement, we have granted security interests in certain of our assets to collateralize our obligations to the surety. We may be required to post letters of credit or other collateral in favor of the surety or our customers. Posting letters of credit in favor of the surety or our customers reduces the borrowing availability under the Facility. To date, we have not been required to make any reimbursements to the surety for bond-related costs. We believe that it is unlikely that we will have to fund significant claims under our surety arrangements in the foreseeable future. As of December 31, 2015, an aggregate of approximately $912.0 million in original face amount of bonds issued by the surety were outstanding. Our estimated remaining cost to complete these bonded projects was approximately $87.0 million as of December 31, 2015.

#### Indemnities

From time to time, pursuant to our service arrangements, we indemnify our customers for claims related to the services we provide under those service arrangements. These indemnification obligations may subject us to indemnity claims, liabilities and related litigation. We are not aware of any material unrecorded liabilities for asserted claims in connection with these indemnification obligations.

## Contractual Obligations

As of December 31, 2015, our future contractual obligations are as follows:

(in thousands) |  | Total |  | Less than 1 Year |  | 1 – 3 Years |  | 3 – 5 Years |  | More than 5 Years |  | Other
Operating lease obligations |  | $ | 4,567 |  |  | $ | 1,717 |  |  | $ | 1,977 |  |  | $ | 807 |  |  | $ | 66 |  |  | $ | — |
Purchase obligations |  |  | 2,164 |  |  |  | 2,164 |  |  |  | — |  |  |  | — |  |  |  | — |  |  |  | — |
Income tax contingencies |  |  | 564 |  |  |  | — |  |  |  | — |  |  |  | — |  |  |  | — |  |  |  | 564 |
Total |  | $ | 7,295 |  |  | $ | 3,881 |  |  | $ | 1,977 |  |  | $ | 807 |  |  | $ | 66 |  |  | $ | 564 |

Excluded from the above table are our multi-employer pension plan contributions, which are determined annually, based on our union employee payrolls, and which cannot be determined for future periods in advance.

The amount of income tax contingencies has been presented in the “Other” column in the table above due to the fact that the period of future payment cannot be reliably estimated. For further information, refer to Note 10 to the Financial Statements.

## Concentration of Credit Risk

We grant trade credit under normal payment terms, generally without collateral, to our customers, which include high credit quality electric utilities, governmental entities, general contractors and builders, owners and managers of commercial and industrial properties. Consequently, we are subject to potential credit risk related to changes in business and economic factors. However, we generally have certain statutory lien rights with respect to services provided. Under certain circumstances such as foreclosures or negotiated settlements, we may take title to the underlying assets in lieu of cash in settlement of receivables. As of December 31, 2015, one customer individually exceeded 10.0% of accounts receivable with approximately 13.0% of the total accounts receivable amount (excluding the impact of allowance for doubtful accounts). As of December 31,

44

TABLE OF CONTENTS

2014, one customer individually exceeded 10.0% of accounts receivable with approximately 14.2% of the total accounts receivable amount (excluding the impact of allowance for doubtful accounts). Management believes the terms and conditions in its contracts, billing and collection policies are adequate to minimize the potential credit risk.

## Inflation

Inflation did not have a significant effect on our results during the years ended December 31, 2015, 2014 or 2013.

## New Accounting Pronouncements

For a discussion of recent accounting pronouncements, see Note 1 — Summary of Significant Accounting Policies in the Notes to the Financial Statements.

## Critical Accounting Policies

The discussion and analysis of our financial condition and results of operations are based on our Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these 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 at the date of the Financial Statements and the reported amounts of revenues and expenses during the reporting period. We evaluate our estimates on an ongoing basis, based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. There can be no assurance that actual results will not differ from those estimates. We believe the following accounting policies affect our more significant judgments and estimates used in the preparation of our Financial Statements:

Revenue Recognition. Revenues under long-term contracts are accounted for under the percentage-of-completion method of accounting. Under the percentage-of-completion method, we estimate profit as the difference between total estimated revenue and total estimated cost of a contract and recognize that profit over the contract term based on either input (e.g., costs incurred under the cost-to-cost method) or output (e.g., units delivered under the units-of-delivery method), as appropriate under the circumstances.

Revenues from our construction services are performed under fixed-price, time-and-equipment, time-and-materials, unit-price, and cost-plus fee contracts. For fixed-price contracts, we use the ratio of cost incurred to date on the contract (excluding uninstalled direct materials) to management’s estimate of the contract’s total cost, to determine the percentage of completion on each contract. This method is used as management considers expended costs to be the best available measure of progression of these contracts. Contract cost includes all direct costs on contracts, including labor and material, subcontractor costs and those indirect costs related to contract performance, such as supplies, fuel, tool repairs and depreciation. We recognize revenues from construction services with fees based on time-and-materials, unit prices, or cost-plus fee as the services are performed and amounts are earned. If contracts include contract incentive or bonus provisions, they are included in estimated contract revenues only when the achievement of such incentive or bonus is reasonably certain.

Contract costs incurred to date and expected total contract costs are continuously monitored during the term of the contract. Changes in job performance, job conditions and final contract settlements are factors that influence management’s assessment of total contract value and the total estimated costs to complete those contracts and therefore, our profit recognition. These changes, which include contracts with estimated costs in excess of estimated revenues, are recognized in contract costs in the period in which the revisions are determined. At the point we anticipate a loss on a contract, we estimate the ultimate loss through completion and recognize that loss in the period in which the possible loss was identified.

A change order is a modification to a contract that changes the provisions of the contract, typically resulting from changes in scope, specifications, design, manner of performance, facilities, equipment, materials, sites, or period of completion of the work under the contract. A claim is an amount in excess of the agreed-upon contract price that the Company seeks to collect from its clients or others for client-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes. Costs related to change orders and claims are

45

TABLE OF CONTENTS

recognized when incurred. Revenue from a change order is included in total estimated contract revenue when it is probable that the change order will result in an addition to contract value and can be reliably estimated. Revenue from a claim is included in total estimated contract revenues, only to the extent that contract costs related to the claim have been incurred, when it is probable that the claim will result in an addition to contract value which can be reliably estimated. No profit is recognized on a claim until final settlement occurs.

The accuracy of our revenue and profit recognition in a given period is dependent on the accuracy of our estimates of the cost to complete each project. Cost estimates for all of our significant projects use a detailed “bottoms up” approach and we believe our experience typically allows us to provide materially reliable estimates. There are a number of factors that can contribute to changes in estimates of contract cost and profitability. The most significant of these include, among others:

| • | the completeness and accuracy of the original bid;

| • | costs associated with scope changes, change orders or claims;

| • | costs of labor and/or materials;

| • | extended overhead due to owner, weather and other delays;

| • | subcontractor performance issues;

| • | changes in productivity expectations;

| • | site conditions that differ from those assumed in the original bid (to the extent contract remedies are unavailable);

| • | the availability and skill level of workers in the geographic location of the project; and

| • | a change in the availability and proximity of equipment and materials.

The foregoing factors as well as the stage of completion of contracts in process and the mix of contracts at different margins may cause fluctuations in gross profit between periods.

We provide warranties to customers on a basis customary to the industry; however, the warranty period does not typically exceed one year. Historically, warranty claims have not been material.

Total revenues do not include sales tax as we consider ourselves a pass-through conduit for collecting and remitting sales taxes.

Insurance. We carry insurance policies, which are subject to certain deductibles, for workers’ compensation, general liability, automobile liability and other coverages. Our deductible for each line of coverage is up to $1.0 million, except for certain health benefit plans, which are subject to a $0.1 million deductible for qualified individuals. Losses up to the deductible amounts are accrued based upon our estimates of the ultimate liability for claims reported and an estimate of claims incurred but not yet reported.

The insurance and claims accruals are based on known facts, actuarial estimates and historical trends. While recorded accruals are based on the ultimate liability, which includes amounts in excess of the deductible, a corresponding receivable for amounts in excess of the deductible is included in current assets in the consolidated balance sheets.

Stock-Based Compensation. We determine compensation expense for stock-based awards based on their estimated fair value at the grant date and recognize the related compensation expense over the vesting period or requisite service period, whichever is shorter. We use the straight-line attribution method to recognize compensation expense related to stock-based awards that have graded vesting and only service conditions. This method recognizes stock compensation expense on a straight-line basis over the requisite service period for the entire award. Stock-based compensation expense is adjusted for changes in estimated and actual forfeitures. We use historical data to estimate the forfeiture rate that we use; however, these estimates are subject to change and may impact the value that will ultimately be recognized as stock compensation expense. We recognize stock-based compensation expense related to performance awards based upon our determination of the potential achievement of the performance target at each reporting date, net of estimated forfeitures.

46

TABLE OF CONTENTS

Impairment of Goodwill and Intangibles. Goodwill and intangible assets with indefinite lives are not amortized. Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives. We review goodwill and intangible assets with indefinite lives for impairment on an annual basis at the beginning of the fourth quarter, or when circumstances change, such as a significant adverse change in the business climate or the decision to sell a business, both of which would indicate that impairment may have occurred. We perform a qualitative assessment to determine whether it is necessary to perform a two-step goodwill impairment test. The qualitative assessment considers financial, industry, segment and macroeconomic factors. If the qualitative assessment indicates a potential for impairment, the two-step method is used to determine if impairment exists. The two-step method begins with a comparison of the fair value of the reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds its fair value, the second step of the process involves a comparison of the implied fair value and carrying value of the goodwill of that reporting unit. The company also performs a qualitative assessment on intangible assets with indefinite lives. If the qualitative assessment indicates a potential for impairment, a quantitative impairment test would be performed to compare the fair value of the indefinite-lived intangible asset with its carrying value. If the carrying value of goodwill or other indefinite lived assets exceeds its implied fair value, an impairment charge would be recorded in the statement of operations.

In 2015, we determined, based on our qualitative analysis, that it was appropriate to perform a two-step analysis. The first step involves a comparison of the fair value of the reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds its fair value, the second step of the process involves a comparison of the implied fair value and carrying value of the goodwill of that reporting unit. If the carrying value of goodwill exceeds its implied fair value, an impairment charge is recorded in the statement of operations. The step one analysis did not indicate that our goodwill or indefinite lived intangible assets were impaired. As a result, no step two analysis was performed.

As a result of the annual qualitative review process in 2014 and 2013, we determined it was not necessary to perform a two-step analysis.

Accounts Receivable and Allowance for Doubtful Accounts. We do not generally charge interest to our customers, and we carry our customer receivables at their face amounts, less an allowance for doubtful accounts. Included in accounts receivable are balances billed to customers pursuant to retainage provisions in certain contracts that are due upon completion of the contracts and acceptance by the customer, or earlier, as provided by the contract. Based on our experience in recent years, the majority of customer balances at each balance sheet date are collected within twelve months. We grant trade credit, on a non-collateralized basis (with the exception of lien rights against the property in certain cases) to our customers, and we are subject to potential credit risk related to changes in business and overall economic activity. We analyze specific accounts receivable balances, historical bad debts, customer credit-worthiness, current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. In the event that a customer balance is deemed to be uncollectible the account balance is written-off against the allowance for doubtful accounts.

| Item 7A. | Quantitative and Qualitative Disclosures About Market Risk

As of December 31, 2015, we were not parties to any derivative instruments. We did not use any material derivative financial instruments during the years ended December 31, 2015, 2014 or 2013.

Borrowings under our Facility are based upon an interest rate that will vary depending upon the prime rate, federal funds rate and LIBOR. If the prime rate, federal funds rate or LIBOR rises, our interest payment obligations will increase and have a negative effect on our cash flow and financial condition. We currently do not maintain any hedging contracts that would limit our exposure to variable rates of interest. We had no borrowings outstanding under the Facility as of December 31, 2015. If we had borrowings outstanding under the Facility as of December 31, 2015, the borrowings would have accrued annual interest at the one-month LIBOR in effect at each month end plus a spread of 1.00%, based upon our current Leverage Ratio, as defined in the Credit Agreement.

# Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our Financial Statements for external purposes in accordance with U.S. GAAP. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we have conducted an evaluation of the effectiveness of our internal control over financial reporting based upon the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this evaluation, our management has concluded that our internal control over financial reporting was effective as of December 31, 2015 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. GAAP.

Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable assurances and may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

Ernst & Young LLP, an independent registered public accounting firm, who audited and reported on the Financial Statements included in this report on Form 10-K, has audited the effectiveness of MYR Group’s internal control over financial reporting as of December 31, 2015 as stated in their report which appears herein.

We have audited the accompanying consolidated balance sheets of MYR Group Inc. as of December 31, 2015 and 2014, and the related consolidated statements of operations and comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 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. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the Financial Statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as 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 MYR Group Inc. at December 31, 2015 and 2014, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), MYR Group Inc.’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 3, 2016 expressed an unqualified opinion thereon.

# Report of Independent Registered Public Accounting Firm

To Board of Directors and Stockholders of
MYR Group Inc.

We have audited MYR Group Inc.’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). MYR Group Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of Financial Statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, MYR Group Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of MYR Group Inc. as of December 31, 2015 and 2014, and the related consolidated statements of operations and comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2015 of MYR Group Inc. and our report dated March 3, 2016 expressed an unqualified opinion thereon.

T&D customers include investor-owned utilities, cooperatives, private developers government-funded utilities, independent power producers, independent transmission companies, industrial facility owners and other contractors. The Company provides a broad range of services, which include design, engineering, procurement, construction, upgrade, maintenance and repair services, with a particular focus on construction, maintenance and repair. The Company also provides C&I electrical contracting services to general contractors, commercial and industrial facility owners, local governments and developers in the western and northeastern United States.

## Significant Accounting Policies

### Consolidation

The accompanying Financial Statements include the results of operations of the Company and its subsidiaries. Significant intercompany transactions and balances have been eliminated.

### Reclassification

A reclassification was made in the current year presentation of the consolidated balance sheets and consolidated statements of stockholder’s equity. The Company adjusted the classification of the impact of shares repurchased, which had previously been recorded as a deduction to additional paid-in capital, to a deduction allocated between additional paid-in capital and retained earnings. As a result of this reclassification, retained earnings were reduced by $14.0 million and additional paid-in capital was increased by the same amount. Additionally, comprehensive income associated with the start-up of the Company’s Canadian operations, which was included in additional paid-in capital in the December 31, 2014 balance sheet, was reclassified to accumulated other comprehensive income.

### Revenue Recognition

Revenues under long-term contracts are accounted for under the percentage-of-completion method of accounting. Under the percentage-of-completion method, the Company estimates profit as the difference between total estimated revenue and total estimated cost of a contract and recognizes that profit over the contract term based on either input (e.g., costs incurred under the cost-to-cost method) or output (e.g., units delivered under the units-of-delivery method), as appropriate under the circumstances.

Revenues from the Company’s construction services are performed under fixed-price, time-and-equipment, time-and-materials, unit-price, and cost-plus fee contracts. For fixed-price contracts, the Company uses the ratio of cost incurred to date on the contract (excluding uninstalled direct materials) to management’s estimate of the contract’s total cost, to determine the percentage of completion on each contract. This method is used as management considers expended costs to be the best available measure of progression of these contracts. Contract cost includes all direct costs on contracts, including labor and material, subcontractor costs and those indirect costs related to contract performance, such as supplies, fuel, tool repairs and depreciation. The Company recognizes revenues from construction services with fees based on time-and-materials, unit prices, or cost-plus fee as the services are performed and amounts are earned.

## 1. Organization, Business and Significant Accounting Policies – (continued)

Contract costs incurred to date and expected total contract costs are continuously monitored during the term of the contract. Changes in job performance, job conditions and final contract settlements are factors that influence management’s assessment of total contract value and the total estimated costs to complete those contracts and therefore, the Company’s profit recognition. These changes, which include contracts with estimated costs in excess of estimated revenues, are recognized in contract costs in the period in which the revisions are determined. At the point the Company anticipates a loss on a contract, the Company estimates the ultimate loss through completion and recognizes that loss in the period in which the possible loss was identified. If contracts include contract incentive or bonus provisions, they are included in estimated contract revenues only when the achievement of such incentive or bonus is reasonably certain.

A change order is a modification to a contract that changes the provisions of the contract, typically resulting from changes in scope, specifications, design, manner of performance, facilities, equipment, materials, sites, or period of completion of the work under the contract. A claim is an amount in excess of the agreed-upon contract price that the Company seeks to collect from its clients or others for client-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes. Costs related to change orders and claims are recognized when incurred. Revenue from a change order is included in total estimated contract revenue when it is probable that the change order will result in an addition to contract value and can be reliably estimated. Revenue from a claim is included in total estimated contract revenues, only to the extent that contract costs related to the claim have been incurred, when it is probable that the claim will result in an addition to contract value which can be reliably estimated. No profit is recognized on a claim until final settlement occurs.

The Company provides warranties to customers on a basis customary to the industry; however, the warranty period does not typically exceed one year. Historically, warranty claims have not been material to the Company.

Total revenues do not include sales tax as the Company considers itself a pass-through conduit for collecting and remitting sales taxes. Sales tax and value added tax collected from customers is included in other current liabilities on our consolidated balance sheets.

### Foreign Currency

The functional currency for the Company’s Canadian operations is the Canadian dollar. Assets and liabilities denominated in Canadian dollars are translated into U.S. dollars at the end-of-period exchange rate. Revenues and expenses are translated using average exchange rates for the periods reported. Cumulative translation adjustments are included as a separate component of accumulated other comprehensive income in shareholders’ equity. Foreign currency transaction gains and losses, arising primarily from changes in exchange rates on foreign currency denominated balances, are recorded in the “other, net” line on the consolidated statements of operations. For the year ended December 31, 2015, the Company recorded $0.3 million of foreign currency losses.

### Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the period reported. Actual results could differ from those estimates.

The most significant estimates are related to estimates of costs to complete on contracts, insurance reserves, income tax reserves, estimates surrounding stock-based compensation, the recoverability of goodwill and intangibles and accounts receivable reserves. Actual results could differ from these estimates.

During 2015, 2014 and 2013, the Company revised its cost estimates on several large multi-year transmission projects, which resulted in the recognition of approximately 0.5%, 1.9% and 0.8% of incremental

57

gross margin, respectively. During 2015, the incremental gross margin resulted in $5.9 million of additional income from operations, $3.6 million of additional net income, and increased diluted earnings per share by $0.17. During 2014, the incremental gross margin resulted in $18.4 million of additional income from operations, $11.6 million of additional net income, and increased diluted earnings per share by $0.54. During 2013, the incremental gross margin resulted in $7.7 million of additional income from operations, $4.9 million of additional net income, and increased diluted earnings per share by $0.23.

### Advertising

Advertising costs are expensed when incurred. Advertising costs, included in selling, general and administrative expenses, were $0.5 million, $0.4 million and $0.3 million for the years ended December 31, 2015, 2014 and 2013, respectively.

### Income Taxes

The Company follows the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recorded for future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, and are measured using the enacted tax rates and laws that are expected to be in effect when the underlying assets or liabilities are recovered or settled.

Interest and penalties related to uncertain income tax positions are included in income tax expense in the accompanying consolidated statements of operations. Interest and penalties actually incurred are charged to interest expense and the “other, net” line, respectively.

### Stock-Based Compensation

The Company determines compensation expense for stock-based awards based on their estimated fair value at the grant date and recognizes the related compensation expense over the vesting period or requisite service period, whichever is shorter. The Company uses the straight-line attribution method to recognize compensation expense related to stock-based awards that have graded vesting and only service conditions. This method recognizes stock compensation expense on a straight-line basis over the requisite service period for the entire award. Stock-based compensation expense is adjusted for changes in estimated and actual forfeitures. The Company uses historical data to estimate the forfeiture rate that it uses; however, these estimates are subject to change and may impact the value that will ultimately be recognized as stock compensation expense. The Company recognizes stock-based compensation expense related to market-based performance awards based on the grant date fair value, which is computed using a Monte Carlo simulation, net of forfeitures. The Company recognizes stock-based compensation expense related to non-market-based performance awards according to its determination of the potential achievement of the performance target at each reporting date, net of estimated forfeitures.

### Earnings Per Share

The Company computes earnings per share using the treasury stock method unless the two-class method is more dilutive. The Company computed earnings per share for the year ended December 31, 2015 using the treasury stock method. Under the treasury stock method, basic earnings per share are computed by dividing net income available to shareholders by the weighted average number of common shares outstanding during the period, and diluted earnings per share are computed by dividing net income available to shareholders by the weighted average number of common shares outstanding during the period plus all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be anti-dilutive.

For the years ended December 31, 2014 and 2013, the Company computed earnings per share using the two-class method because that method resulted in a more dilutive effect than the treasury stock method. The two-class method is an earnings allocation formula that determines earnings per share for common stock and

58

## 1. Organization, Business and Significant Accounting Policies – (continued)

participating securities according to dividends declared and participation rights in undistributed earnings. Under the two-class method, the Company’s unvested grants of restricted stock that contained non-forfeitable rights to dividends were treated as participating securities and were excluded from the computation of basic and diluted earnings per share. All shares of restricted stock granted since 2013 are not participating because the grant agreements contain provisions that dividends, if declared, will be forfeited if the grantee leaves the Company before the stock is vested.

### Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. As of December 31, 2015 and 2014, the Company held its cash in checking accounts or in highly liquid money market funds.

### Accounts Receivable and Allowance for Doubtful Accounts

The Company does not charge interest to its customers and carries its customer receivables at their face amounts, less an allowance for doubtful accounts. Included in accounts receivable are balances billed to customers pursuant to retainage provisions in certain contracts that are due upon completion of the contract and acceptance by the customer, or earlier as provided by the contract. Based on the Company’s experience in recent years, the majority of customer balances at each balance sheet date are collected within twelve months. As is common practice in the industry, the Company classifies all accounts receivable, including retainage, as current assets. The contracting cycle for certain long-term contracts may extend beyond one year, and accordingly, collection of retainage on those contracts may extend beyond one year. The Company estimates that approximately 90% of retainage recorded at December 31, 2015 will be collected within one year.

The Company grants trade credit, on a non-collateralized basis (with the exception of lien rights against the property in certain cases), to its customers and is subject to potential credit risk related to changes in business and overall economic activity. The Company analyzes specific accounts receivable balances, historical bad debts, customer credit-worthiness, current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. In the event that a customer balance is deemed to be uncollectible, the account balance is written-off against the allowance for doubtful accounts.

### Classification of Construction Contract-related Assets and Liabilities

Costs and estimated earnings in excess of billings on uncompleted contracts are presented as a current asset in the accompanying consolidated balance sheets, and billings in excess of costs and estimated earnings on uncompleted contracts are presented as a current liability in the accompanying consolidated balance sheets. The Company’s contracts vary in duration, with the duration of some larger contracts exceeding one year. Consistent with industry practices, the Company includes the amounts realizable and payable under contracts, which may extend beyond one year, in current assets and current liabilities. These balances are generally settled within one year.

### Construction Materials Inventory

When required, the Company provides construction materials for projects. Construction materials which have not yet been installed are included in construction materials inventory. Construction materials inventories are stated at the lower of cost or market, as determined by the specific identification method. As of December 31, 2015 and 2014, the Company did not carry any construction materials inventory.

### Property and Equipment

Property and equipment is carried at cost. Depreciation is computed using the straight-line method over estimated useful lives. Major modifications or refurbishments which extend the useful life of the assets are capitalized and depreciated over the adjusted remaining useful life of the assets. Upon retirement or

59

disposition of property and equipment, the cost and related accumulated depreciation are removed and any resulting gain or loss is recognized into income from operations. The cost of maintenance and repairs is charged to expense as incurred. Additional financial information related to our property and equipment is provided in Note 6 to the Financial Statements.

The Company leases certain real estate, construction equipment and office equipment. Real estate is generally leased for terms up to ten years in duration. No new construction equipment leases have been entered into since 2010, although the Company continues to rent some equipment under short-term, cancelable agreements. The terms and conditions of leases, if material, are reviewed at inception to determine the classification (operating or capital) of the lease. Nonperformance-related default covenants, cross-default provisions, subjective default provisions and material adverse change clauses contained in material lease agreements, if any, are also evaluated to determine whether those clauses affect lease classification in accordance with Accounting Standards Codification (“ASC”) Topic 840-10-25.

### Insurance

The Company carries insurance policies, which are subject to certain deductibles, for workers’ compensation, general liability, automobile liability and other coverages. The deductible for each line of coverage is up to $1.0 million, except for certain of the Company’s health insurance benefit plans, which are subject to a $0.1 million deductible for qualified individuals. Losses up to the deductible amounts are accrued based upon the Company’s estimates of the ultimate liability for claims reported and an estimate of claims incurred but not yet reported.

The insurance and claims accruals are based on known facts, actuarial estimates and historical trends. While recorded accruals are based on the ultimate liability, which includes amounts in excess of the deductible, a corresponding receivable for amounts in excess of the deductible is included in current assets in the consolidated balance sheets.

### Goodwill and Intangible Assets

Goodwill and intangible assets with indefinite lives are not amortized. Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives. The Company reviews goodwill and intangible assets with indefinite lives for impairment on an annual basis at the beginning of the fourth quarter, or when circumstances change, such as a significant adverse change in the business climate or the decision to sell a business, both of which would indicate that impairment may have occurred. The Company performs a qualitative assessment to determine whether it is necessary to perform a two-step goodwill impairment test. The qualitative assessment considers financial, industry, segment and macroeconomic factors. If the qualitative assessment indicates a potential for impairment, the two-step method is used to determine if impairment exists. The two-step method begins with a comparison of the fair value of the reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds its fair value, the second step of the process involves a comparison of the implied fair value and carrying value of the goodwill of that reporting unit. The company also performs a qualitative assessment on intangible assets with indefinite lives. If the qualitative assessment indicates a potential for impairment, a quantitative impairment test would be performed to compare the fair value of the indefinite-lived intangible asset with its carrying value. If the carrying value of goodwill or other indefinite-lived assets exceeds its implied fair value, an impairment charge would be recorded in the statement of operations.

In 2015, the Company determined, based on our qualitative analysis, that it was appropriate to perform a two-step analysis. The first step involves a comparison of the fair value of the reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds its fair value, the second step of the process involves a comparison of the implied fair value and carrying value of the goodwill of that reporting unit. If the carrying value of goodwill exceeds its implied fair value, an impairment charge is recorded in the

## 1. Organization, Business and Significant Accounting Policies – (continued)

statement of operations. The step one analysis did not indicate that the Company’s goodwill or indefinite lived intangible assets were impaired. As a result, no step two analysis was performed.

As a result of the annual qualitative review process in 2014 and 2013, the Company determined it was not necessary to perform a two-step analysis. Additional financial information related to our goodwill and intangible assets is provided in Note 7 to the Financial Statements.

### Concentrations

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company maintains substantially all of its cash and cash equivalent balances with large financial institutions which are believed to be high quality institutions.

The Company grants trade credit under normal payment terms, generally without collateral, to its customers, which include high credit quality electric utilities, governmental entities, general contractors and builders, owners and managers of commercial and industrial properties. Consequently, the Company is subject to potential credit risk related to changes in business and economic factors. However, the Company generally has certain statutory lien rights with respect to services provided. Under certain circumstances such as foreclosures or negotiated settlements, the Company may take title to the underlying assets in lieu of cash in settlement of receivables. As of December 31, 2015, one customer individually exceeded 10.0% of consolidated accounts receivable with an aggregate of approximately 13.0% of the total consolidated accounts receivable amount (excluding the impact of allowance for doubtful accounts). As of December 31, 2014, one customer individually exceeded 10.0% of consolidated accounts receivable with an aggregate of approximately 14.2% of the total consolidated accounts receivable amount (excluding the impact of allowance for doubtful accounts). The Company believes the terms and conditions in its contracts, billing and collection policies are adequate to minimize the potential credit risk.

The Company is subject to a concentration of risk because it derives a significant portion of its revenues from a few customers. The Company’s top ten customers accounted for approximately 44.6%, 46.5% and 57.8% of consolidated revenues for the years ended December 31, 2015, 2014 and 2013, respectively. For the years ended December 31, 2015, 2014 and 2013, no single customer accounted for more than 10.0% of annual revenues.

As of December 31, 2015, approximately 91% of the Company’s craft labor employees were covered by collective bargaining agreements. Although the majority of these agreements prohibit strikes and work stoppages, the Company cannot be certain that strikes or work stoppages will not occur in the future.

## Recent Accounting Pronouncements

Changes to U.S. GAAP are typically established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). The Company considers the applicability and impact of all ASUs. The Company, based on its assessment, determined that any recently issued or proposed ASUs not listed below are either not applicable to the Company or have minimal impact on its Financial Statements.

### Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments under this pronouncement will change the way all leases with a duration of one year of more are treated. Under this guidance, lessees will be required to recognize virtually all leases on the balance sheet as a right-of-use asset and an associated financing lease liability or capital lease liability. The right-of-use asset represents the lessee’s right to use, or control the use of, a specified asset for the specified lease term. The lease liability represents the lessee’s obligation to make lease payments arising from the lease, measured on a discounted

61

## 1. Organization, Business and Significant Accounting Policies – (continued)

basis. Based on certain characteristics, leases are classified as financing leases or operating leases. Financing lease liabilities, those that contain provisions similar to capitalized leases, are amortized like capital leases are under current accounting, as amortization expense and interest expense in the statement of operations. Operating lease liabilities are amortized on a straight-line basis over the life of the lease as lease expense in the statement of operations. This update is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2018. The Company is evaluating the impact this pronouncement will have on its policies and procedures pertaining to its existing and future lease arrangements, disclosure requirements and on the Company’s Financial Statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The amendments under this pronouncement may change how an entity recognizes revenue from contracts it enters to transfer goods, services or nonfinancial assets to its customers. These changes created a comprehensive framework for all entities in all industries to apply in the determination of when to recognize revenue, and, therefore, supersede virtually all existing revenue recognition requirements and guidance. This framework is expected to result in less complex guidance in application while providing a consistent and comparable methodology for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: Step 1: Identify the contract(s) with the customer; Step 2: Identify the performance obligations in the contract; Step 3: Determine the transaction price; Step 4: Allocate the transaction price to the performance obligations in the contract; Step 5: Recognize revenue when, or as, the entity satisfies the performance obligations. In addition, the amendments require expanded disclosure to enable the users of the financial statements to understand the nature, timing and uncertainty of revenue and cash flow arising from contracts with customers. The update is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2016. On August 16, 2015, the FASB deferred the effective date by one year to December 15, 2017 for annual reporting periods beginning after that date, permitting early adoption of the standard, but not before the original effective date of December 15, 2016. The Company is evaluating the impact of this pronouncement on its policies and procedures pertaining to recognition of revenue from contracts with customers, the pronouncement’s expanded disclosure requirements and the impact on the Company’s Financial Statements.

### Recently Adopted Accounting Pronouncements

In November 2015, the FASB issued ASU 2015-17 Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The amendments in ASU 2015-17 simplify the accounting for, and presentation of, deferred taxes by eliminating the need to separately classify the current amount of deferred tax assets or liabilities. Instead, aggregated deferred tax assets and liabilities are classified and reported as non-current assets or liabilities. The update is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2016. Early adoption is permitted for financial statements that have not been issued. The Company elected to prospectively adopt ASU 2015-17 on December 31, 2015 and reclassified all deferred tax assets in current assets to deferred income tax liabilities. The adoption of ASU 2015-17 did not have a significant impact on the Company’s Financial Statements.

In September 2015, the FASB issued ASU 2015-16 Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The amendments in ASU 2015-16 simplify the accounting for adjustments to provisional amounts by eliminating the requirements to record those adjustments retrospectively. The update is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been issued. The Company elected to adopt ASU 2015-16 in September 2015, which did not have a significant impact on the Company’s Financial Statements.

62

## 1. Organization, Business and Significant Accounting Policies – (continued)

In February 2013, the FASB issued ASU No. 2013-04, Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date. This update requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. Obligations within the scope of this update include debt arrangements, other contractual obligations and settled litigation and judicial rulings. The Company adopted this ASU in January 2014 and there was no impact on its Financial Statements.

## 2. Acquisitions

#### E.S. Boulos Company

On April 13, 2015, the Company acquired substantially all of the assets of E.S. Boulos Company (“ESB”), one of New England’s largest and most experienced electrical contractors with over 95 years in operation, from a subsidiary of Eversource Energy. The total consideration paid was approximately $11.4 million, subject to working capital adjustments, which was funded through existing cash resources of the Company. Headquartered in Westbrook, Maine, ESB offers construction capabilities under the Company’s T&D segment, including substation, transmission and distribution construction. ESB also provides commercial and industrial electrical construction under its C&I segment, including a wide range of commercial electrical construction services.

The results of operations for ESB are included in the Company’s consolidated statement of operations and the T&D and C&I segments from the date of acquisition. Costs of approximately $0.4 million related to the acquisition were included in selling, general and administrative expenses in the consolidated statement of operations. The purchase accounting for ESB was complete as of December 31, 2015. The following table summarizes the allocation of the opening balance sheet from the date of acquisition through December 31, 2015:

(in thousands) |  | (as of acquisition date) April 13, 2015 |  | Measurement Period Adjustments |  | (adjusted acquisition amounts as of) December 31, 2015

#### High Country Line Construction, Inc.

On November 24, 2015, the Company acquired all of the outstanding common stock of High Country Line Construction, Inc. (HCL). The acquisition of HCL expands the Company’s T&D construction services, predominantly in the western United States. The preliminary acquisition date fair value of consideration transferred was $1.7 million, net of cash acquired, of which $0.5 million was preliminarily allocated to goodwill. The Company’s process of valuing the acquired assets and liabilities is in its preliminary stages. Costs of approximately $0.2 million related to the acquisition were included in selling, general and administrative expenses in the consolidated statement of operations.

## 3. Fair Value Measurements

The Company uses the three-tier hierarchy of fair value measurement, which prioritizes the inputs used in measuring fair value based upon their degree of availability in external active markets. These tiers include: Level 1 (the highest priority), defined as observable inputs, such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3 (the lowest priority), defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

As of December 31, 2015 and 2014, the Company determined that the carrying value of cash and cash equivalents approximated fair value based on Level 1 inputs.

## 4. Accounts Receivable

Accounts receivable consisted of the following at December 31:

(in thousands) |  | 2015 |  | 2014
Contract receivables |  | $ | 159,794 |  |  | $ | 120,295 |

The increase in the gross carrying amount of goodwill and intangible assets as of December 31, 2015 compared to December 31, 2014 was due to the ESB and HCL acquisitions. Additional financial information related to the these acquisitions is provided in Note 2 to the Financial Statements.

Customer relationships and backlog are being amortized on a straight-line method over an estimated useful life of approximately 12 years and 1 year, respectively, and have been determined to have no residual value. Amortizable trade names are being amortized on a straight-line method over an estimated useful life of approximately 15 years. Infinite-lived trade names have been determined to have indefinite lives and, therefore, are not being amortized. Intangible asset amortization expense was $0.6 million for the year ended December 31, 2015 and $0.3 million for the years ended December 31, 2014 and 2013. Intangible asset amortization expense for the years subsequent to December 31, 2015 is expected to be approximately $0.5 million in 2016, $0.4 million for the years 2017 and 2018 and $0.1 million for each of the years from 2019 to 2026.

## 9. Debt and Borrowing Arrangements

On December 21, 2011, the Company entered into a five-year syndicated credit agreement (the “Credit Agreement”) with a facility of $175.0 million (the “Facility”). The entire Facility is available for revolving loans and the issuance of letters of credit. The Company has an option to increase the commitments under the Facility or enter into incremental term loans, subject to certain conditions, by up to an additional $75.0 million upon receipt of additional commitments from new or existing lenders. Up to $25.0 million of the Facility is available for swingline loans.

Revolving loans under the Credit Agreement bear interest, at the Company’s option, at either (1) the ABR, which is the greatest of the Prime Rate, the Federal Funds Effective Rate plus 0.50% or LIBOR plus 1.00%, plus in each case an applicable margin ranging from 0.00% to 1.00%; or (2) LIBOR plus an applicable margin ranging from 1.00% to 2.00%. The applicable margin is determined based on the Company’s leverage ratio (the “Leverage Ratio”), defined under the Credit Agreement as consolidated total indebtedness divided by consolidated EBITDA as defined by the Credit Agreement (“Consolidated EBITDA”). Letters of credit issued under the Facility are subject to a letter of credit fee of 1.00% to 2.00%, based on the Company’s leverage ratio and a facing fee of 0.125%. Swingline loans bear interest at the ABR rate. The Company is currently required to pay a 0.2% commitment fee on the unused portion of the Facility.

Subject to certain exceptions, the Facility is secured by substantially all of the United States assets of the Company and its subsidiaries and by a pledge of all of the capital stock of the Company’s subsidiaries. The Company’s subsidiaries also guarantee the repayment of all amounts due under the Credit Agreement. The Credit Agreement provides for customary events of default. If an event of default occurs and is continuing, on the terms and subject to the conditions set forth in the Credit Agreement, amounts outstanding under the Facility may be accelerated and may become or be declared immediately due and payable.

Under the Credit Agreement, the Company is subject to certain financial covenants and must maintain a maximum Leverage Ratio of 3.0 and a minimum interest coverage ratio of 3.0, (“Interest Coverage Ratio”), defined under the Credit Agreement as Consolidated EBITDA divided by interest expense. The Company was in compliance with the financial covenants at December 31, 2015, as well as in all previous quarters. The Credit Agreement also contains a number of covenants including limitations on asset sales, investments, indebtedness and liens.

The Company had no revolving loans outstanding as of December 31, 2015 and 2014. As of December 31, 2015 and 2014, the Company had approximately $19.3 million in irrevocable standby letters of credit outstanding at an interest rate of 1.125%. The Company had $155.7 million available for borrowing under the Facility as of December 31, 2015.

## 10. Income Taxes – (continued)

As of December 31, 2015, the Company had no undistributed earnings of our Canadian subsidiary. We expect future earnings to be reinvested. Accordingly, no provision for U.S. income taxes or foreign withholding taxes has been made.

The Company is subject to taxation in various jurisdictions. The Company is currently under examination by U.S. federal authorities for the open tax years 2012 through 2014 and subject to examination by various state authorities for the years 2011 through 2014.

The Company has recorded a liability for unrecognized tax benefits related to tax positions taken on its various income tax returns. If recognized, the entire amount of unrecognized tax benefits would favorably impact the effective tax rate that is reported in future periods. The Company anticipates the total unrecognized tax benefits will be reduced within the next 12 months due to the lapses in the applicable statutes of limitations, as well as pending federal tax settlements for the three years under examination. The adjustment related to these items is estimated at approximately $0.3 million. Interest and penalties related to uncertain income tax positions are included as a component of income tax expense in the Financial Statements.

The following is a reconciliation of the beginning and ending liability for unrecognized tax benefits at December 31:

(in thousands) |  | 2015 |  | 2014
Balance at beginning of period |  | $ | 507 |  |  | $ | 657 |
Gross increases in current period tax positions |  |  | 62 |  |  |  | 93 |
Gross increases in prior period tax positions |  |  | 19 |  |  |  | — |
Gross decreases in prior period tax positions |  |  | (163 | ) |  |  | (243 | )
Balance at end of period |  |  | 425 |  |  |  | 507 |
Accrued interest and penalties at end of period |  |  | 139 |  |  |  | 223 |
Total liability for unrecognized tax benefits |  | $ | 564 |  |  | $ | 730 |

The liability for unrecognized tax benefits, including accrued interest and penalties, was included in other liabilities in the accompanying consolidated balance sheets. The amount of interest and penalties charged or credited to income tax expense as a result of the unrecognized tax benefits was not significant in the years ended December 31, 2015, 2014 and 2013.

## 11. Commitments and Contingencies

### Letters of Credit

As of both December 31, 2015 and 2014, the Company had irrevocable standby letters of credit outstanding of approximately $19.3 million, including $17.5 million related to the Company’s payment obligation under its insurance programs and approximately $1.8 million related to contract performance obligations.

### Leases

The Company leases real estate, construction equipment and office equipment under operating leases with remaining lease terms ranging from one to less than six years. As of December 31, 2015, future minimum lease payments for these operating leases were as follows: $1.7 million for 2016, $1.1 million for 2017, $0.9 million for 2018, $0.7 million for 2019, $0.1 million for 2020 and $0.1 million for 2021. The Company had no leases in effect in 2015 or 2014 that included guaranteed residual values.

Rent expense includes lease payments as well as rent on items that are rented under cancellable rental agreements. Total rent expense for the years ended December 31, 2015, 2014 and 2013, was $57.2 million, $41.1 million and $51.2 million, respectively.

## 11. Commitments and Contingencies – (continued)

### Purchase Commitments for Construction Equipment

As of December 31, 2015, the Company had approximately $2.2 million in outstanding purchase obligations for certain construction equipment, with most of the cash outlay scheduled to occur during the next three months.

### Insurance and Claims Accruals

The Company carries insurance policies, which are subject to certain deductibles, for workers’ compensation, general liability, automobile liability and other coverages. The deductible for each line of coverage is up to $1.0 million, except for certain health benefit plans which are subject to a $0.1 million deductible for qualified individuals. Losses up to the deductible amounts are accrued based upon the Company’s estimates of the ultimate liability for claims reported and an estimate of claims incurred but not yet reported.

The insurance and claims accruals are based on known facts, actuarial estimates and historical trends. While recorded accruals are based on the ultimate liability, which includes amounts in excess of the deductible, a corresponding receivable for amounts in excess of the stop loss deductible is included in current assets in the consolidated balance sheets at December 31:

(in thousands) |  | 2015 |  | 2014 |  | 2013
Balance at beginning of period |  | $ | 39,480 |  |  | $ | 39,111 |  |  | $ | 39,583 |
Net increases in reserves |  |  | 15,686 |  |  |  | 16,220 |  |  |  | 16,861 |
Net payments made |  |  | (18,199 | ) |  |  | (15,851 | ) |  |  | (17,333 | )
Balance at end of period |  | $ | 36,967 |  |  | $ | 39,480 |  |  | $ | 39,111 |

Insurance expense, including premiums, for workers’ compensation, general liability, automobile liability, employee health benefits, and other coverages for the years ended December 31, 2015, 2014 and 2013 was $23.6 million, $21.0 million and $20.1 million, respectively.

### Performance and Payment Bonds

In certain circumstances, the Company is required to provide performance and payment bonds in connection with its future performance on contractual commitments. The Company has indemnified its sureties for any expenses paid out under these bonds. As of December 31, 2015, an aggregate of approximately $912.0 million in original face amount of bonds issued by the surety were outstanding. Our estimated remaining cost to complete these bonded projects was approximately $87.0 million as of December 31, 2015.

### Indemnities

From time to time, pursuant to its service arrangements, the Company indemnifies its customers for claims related to the services it provides under those service arrangements. These indemnification obligations may subject the Company to indemnity claims, liabilities and related litigation. The Company is not aware of any material unrecorded liabilities for asserted claims in connection with these indemnification obligations.

### Collective Bargaining Agreements

Many of the Company’s subsidiaries’ craft labor employees are covered by collective bargaining agreements. The agreements require the subsidiaries to pay specified wages, provide certain benefits and contribute certain amounts to multi-employer pension plans. If a subsidiary withdraws from one or more multi-employer pension plans or if the plans were to otherwise become underfunded, the subsidiary could be assessed the funding status of liabilities for additional contributions related to the underfunding of these plans. Although we have been informed that several of the multi-employer pension plans to which our subsidiaries contribute have been classified as being in a “critical” status, we are not currently aware of any potential

significant liabilities related to this issue. See Note 13 to the Financial Statements for further information related to the Company’s participation in multi-employer plans.

### Litigation and Other Legal Matters

The Company is from time-to-time party to various lawsuits, claims, and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contract and/or property damages, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, the Company records reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company does not believe that any of these proceedings, separately or in the aggregate, would be expected to have a material adverse effect on the Company’s financial position, results of operation or cash flows.

The Company is routinely subject to other civil claims, litigation and arbitration, and regulatory investigations arising in the ordinary course of our present business as well as in respect of our divested businesses. Some of these claims and litigations include claims related to the Company’s current services and operations, and asbestos-related claims concerning historic operations of a predecessor affiliate. The Company believes that it has strong defenses to these claims as well as insurance coverage that could contribute to any settlement or liability in the event any asbestos-related claim is not resolved in the Company’s favor. These claims have not had a material impact on the Company to date, and the Company believes that the likelihood that a future material adverse outcome will result from these claims is remote. However, if facts and circumstances change in the future, the Company cannot be certain that an adverse outcome of one or more of these claims would not have a material adverse effect on the Company’s financial condition, results of operations or cash flows.

In January 2013, The L. E. Myers Co. (“L. E. Myers”) was joined as a defendant in Northern States Power Company (Wisconsin) v. The City of Ashland, Wisconsin et al., filed in the U.S. District Court for the Western District of Wisconsin. Northern States Power Company alleged that named defendants, including L. E. Myers, contributed to contamination at the Ashland Lakefront Superfund Site in Ashland, Wisconsin. Specifically, the lawsuit alleged that L. E. Myers operated a manufactured gas plant at the site for 6 to 12 years of the plant’s operation during the time frame from 1885 to 1947. In April 2015, L. E. Myers negotiated a settlement of this litigation with Northern States Power Company, funded largely by L. E. Myers’ insurance carriers, with L. E. Myers’ contribution being $230,000.

## 12. Stock-Based Compensation

The Company maintains two equity compensation plans under which stock-based compensation has been granted, the 2006 Stock Option Plan (the “2006 Plan”) and the 2007 Long-Term Incentive Plan (Amended and Restated as of May 1, 2014) (the “LTIP”). Upon the adoption of the LTIP, awards were no longer granted under the 2006 Plan. The LTIP was approved by our stockholders and provides for grants of (a) incentive stock options qualified as such under U.S. federal income tax laws, (b) stock options that do not qualify as incentive stock options, (c) stock appreciation rights, (d) restricted stock awards, (e) performance awards, (f) phantom stock, (g) stock bonuses, (h) dividend equivalents, or (i) any combination of such awards. The LTIP permits the granting of up to 4,000,000 shares to directors, officers and other employees of the Company. Grants of awards to employees are approved by the Compensation Committee of the Board of Directors and grants to independent members of the Board of Directors are approved by the Board of Directors. All awards are made with an exercise price or base price, as the case may be, that is not less than the full fair market value per share on the date of grant. No stock option or stock appreciation right may be exercised more than 10 years from the date of grant.

NOTES TO FINANCIAL STATEMENTS

## 12. Stock-Based Compensation – (continued)

Shares issued as a result of stock option exercises or stock grants may be made available from authorized unissued shares of common stock or treasury stock. The Company believes that it currently has adequate authorized unissued shares to meet any requirements to issue shares during 2016.

### Stock Options

The Company did not award any stock options in 2015 or 2014. Stock options granted prior to 2014 to employees or directors vest ratably over a three- or four-year vesting period and were granted with an exercise price equal to the market price of the Company’s stock on the date of grant. The Company used the Black-Scholes-Merton option-pricing model to estimate the fair value of options as of the date of grant. The resulting compensation costs are amortized on a straight-line basis over the vesting period. The expected term of awards granted under the LTIP was determined using the simplified method as outlined in the applicable guidance because the Company did not have sufficient historical exercise data when the options were granted. The expected volatility was determined based on the historical volatility of the Company’s stock. The risk-free interest rate was based on U.S. Treasury zero-coupon issues with a remaining term commensurate with the expected term of the award. The expected dividend yield was based on the Company’s intent to not issue cash dividends.

The following summarizes the assumptions used in determining the fair value of stock options granted for fixed awards with graded vesting schedules during the year ended December 31, 2013:

|  | 2013
Risk-free interest rate |  |  | 1.0% |
Expected dividend yield |  |  | 0.0% |
Weighted average expected volatility |  |  | 50% |
Expected term |  |  | 6.0 years |
Weighted average grant-date fair value |  | $ | 11.74 |

Following is a summary of stock option activity for the three-year period ending December 31, 2015:

### Restricted Stock

Restricted stock awards granted to non-employee directors and eligible employees in 2015 vest ratably, on an annual basis, over three years. The grant date fair value of the restricted stock was equal to the closing market price of the Company’s common stock on the date of grant. During the restriction period, the restricted stockholders are entitled to the same rights as a common stockholder with respect to the shares, including the right to vote and receive dividends: however, starting with the 2014 grants, any dividends on restricted stock will be deferred and paid only when the stock vests. Restricted stock awards are also subject to certain claw-back provisions, as defined in the grant agreements.

Following is a summary of restricted stock activity for the three-year period ending December 31, 2015:

|  | Shares |  | Per Share Weighted- Average Grant Date Fair Value
Outstanding unvested at January 1, 2013 |  |  | 185,764 |  |  | $ | 19.54 |

### Phantom Stock Units

Phantom stock unit awards granted to Canadian non-employee directors in 2015 vest ratably, on an annual basis, over three years and are settled in stock. The phantom stock unit agreements contain tandem dividend provisions which allow grantees to accrue and receive dividends, if any are declared and paid. The grant date fair value of the phantom stock units was equal to the closing market price of the Company’s common stock on the date of grant. A total of 3,804 phantom stock units were issued during 2015, at a grant date fair value of $29.57, and are outstanding as of December 31, 2015.

### Performance Awards

The Company has granted performance awards under which shares of the Company’s common stock may be earned based on the Company’s performance compared to certain metrics. The number of shares actually earned under a performance award may vary from zero to 200% of the target shares awarded, based upon the Company’s performance compared to the metrics. The metrics used are determined at grant by the Compensation Committee of the Board of Directors and may be either based on performance compared to an internal measure, such as return on invested capital (“ROIC”) or return on equity (“ROE”), or the metric may be based on market performance, such as total shareholder return (“TSR”). The 2015 performance award grants were allocated evenly between two performance metrics; ROIC and relative TSR.

ROIC is defined by the Company as net income, less any dividends, divided by stockholders’ equity plus net debt (total debt less cash and marketable securities) at the beginning of the performance period. The ROIC-based target shares awarded in 2015 were valued at $30.16, which represented the closing price of the Company’s stock on the date of grant and are measured over a three-year performance period ending December 31, 2017.

TSR is defined by the Company as the change in the fair market value, adjusted for dividends, of a company’s stock. The TSR of the Company’s stock will be compared to the TSR of a peer group of companies defined at the time of the grant. For the 2015 grant of TSR-based performance awards, TSR will be calculated using the average stock price of the 20 trading days prior to January 1, 2015 and compared to the average stock price of the 20 trading days prior to December 31, 2017. Because TSR is a market-based performance metric, the Company used a Monte Carlo simulation model to calculate the fair value of the grant made in 2015, which resulted in a fair value of $47.24 per share.

The 143,608 performance awards outstanding as of December 31, 2015 are split evenly between ROIC performance shares and TSR performance shares.

### Stock-based Compensation Expense

The Company recognized stock-based compensation expense of approximately $4.8 million, $4.7 million and $3.5 million for the years ended December 31, 2015, 2014 and 2013, respectively, in selling, general and administrative expenses. As of December 31, 2015, there was approximately $5.7 million of total unrecognized stock-based compensation expense related to awards granted under the LTIP, net of estimated forfeitures. This included $0.1 million of unrecognized compensation cost related to unvested stock options to be recognized over a remaining weighted average vesting period of approximately 0.2 years, $2.9 million of unrecognized compensation cost related to unvested restricted stock expected to be recognized over a remaining weighted average vesting period of approximately 1.6 years and $2.7 million of unrecognized compensation cost related to unvested performance awards, expected to be recognized over a remaining weighted average vesting period of approximately 1.5 years. Award agreements for restricted stock and phantom stock granted to non-employee directors after 2013 contained provisions which call for the vesting of all shares awarded upon change in control or resignation from the board for any reason except breach of fiduciary duty. As a result of these provisions, the fair value of restricted stock granted to the non-employee directors after 2013 was expensed on the date of the grant.

## 13. Employee Benefit Plans

The Company has a profit sharing and thrift employee benefit plan in effect for all eligible employees. Company contributions under this defined contribution plan are based upon a percentage of income with limitations as defined by the plan. Contributions for the years ended December 31, 2015, 2014 and 2013 amounted to $3.4 million, $6.9 million, and $4.9 million, respectively. The Company also has an employee benefit plan in effect for certain non-union hourly employees. Company contributions under this defined contribution plan are based upon a percentage of income with limitations as defined by the plan. Contributions for the years ended December 31, 2015, 2014 and 2013 amounted to $0.7 million, $0.6 million and $0.6 million, respectively.

The Company contributes to a number of multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover its union-represented employees, who are represented by over 100 local unions. The related collective-bargaining agreements between those organizations and the Company, which specify the rate at which the Company must contribute to the multi-employer defined pension plan, expire at different times between 2016 and 2018.

The risks of participating in these multiemployer defined benefit pension plans are different from single-employer plans in the following aspects:

| 1) | Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.

| 2) | If a participating employer stops contributing to a plan, the unfunded obligations of the plan may be borne by the remaining participating employers.

| 3) | If the Company chooses to stop participating in a multiemployer plan, it may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

The amount of additional funds, if any, that the Company may be obligated to contribute to these plans in the future cannot be estimated due to uncertainty of the future levels of work that require the specific use of union employees covered by these plans, as well as the future contribution levels and possible surcharges on contributions applicable to these plans.

## 13. Employee Benefit Plans – (continued)

The following table summarizes plan information relating to the Company’s participation in multi-employer defined benefit pension plans, including company contributions for the last three years, the status under the Pension Protection Act (PPA) of the plans and whether the plans are subject to a funding improvement or rehabilitation plan, or contribution surcharges. The most recent zone status is for the plan’s year-end indicated in the table. The zone status is based on information that the Company received from the plan, as well as from publicly available information on the U.S. Department of Labor website. The PPA zone status for plan years ending on December 31, 2015 has not been listed because Forms 5500 were not yet available. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded. Also listed in the table below are the Company’s contributions to defined contribution plans.

## 14. Segment Information

MYR Group is a specialty contractor serving the U.S. electrical infrastructure market. It also has operations in parts of Canada. The Company has two reporting segments, each a separate operating segment, which are referred to as T&D and C&I. Performance measurement and resource allocation for the reporting segments are based on many factors. The primary financial measures used to evaluate the segment information are contract revenues and income from operations, excluding general corporate expenses. General corporate expenses include corporate facility and staffing costs, which includes safety, professional fees, management fees, and intangible amortization. The accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies.

Transmission and Distribution: The T&D segment provides a broad range of services on electric transmission and distribution networks and substation facilities which include design, engineering, procurement, construction, upgrade, maintenance and repair services with a particular focus on construction, maintenance and repair. T&D services include the construction and maintenance of high voltage transmission lines, substations and lower voltage underground and overhead distribution systems. The T&D segment also provides emergency restoration services in response to hurricane, ice or other storm-related damage. T&D customers include investor-owned utilities, cooperatives, private developers, government-funded utilities, independent power producers, independent transmission companies, industrial facility owners and other contractors.

Commercial and Industrial: The C&I segment provides services such as the design, installation, maintenance and repair of commercial and industrial wiring, installation of traffic networks and the installation of bridge, roadway and tunnel lighting. Typical C&I contracts cover electrical contracting services for airports, hospitals, data centers, hotels, stadiums, convention centers, manufacturing plants, processing facilities, waste-water treatment facilities, mining facilities and transportation control and management systems.

The Company does not identify capital expenditures and total assets by segment in its internal financial reports due in part to the shared use of a centralized fleet of vehicles and specialized equipment. Identifiable assets, consisting of contract receivables, costs and estimated earnings in excess of billings on uncompleted contracts, construction materials inventory, goodwill and intangibles for each segment are as follows as of December 31:

For the year ended December 31, 2015, the Company had Canadian contract revenues of $1.5 million, of which $1.4 million and $0.1 million is attributable to the T&D and C&I segments, respectively. The Company had no Canadian contract revenues in the years ended December 31, 2014 and 2013. As of December 31, 2015, $1.9 million of identifiable assets were attributable to Canadian operations.

## 15. Earnings Per Share

The Company computes earnings per share using the treasury stock method unless the two-class method is more dilutive. The Company computed earnings per share for the year ended December 31, 2015 using the treasury stock method. Under the treasury stock method, basic earnings per share are computed by dividing net income available to shareholders by the weighted average number of common shares outstanding during the period, and diluted earnings per share are computed by dividing net income available to shareholders by share is computed using the weighted average number of common shares outstanding during the period adjusted for plus all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be anti-dilutive.

For the years ended December 31, 2014 and 2013, the Company computed earnings per share using the two-class method because that method resulted in a more dilutive effect than the treasury stock method. The two-class method is an earnings allocation formula that determines earnings per share for common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under the two-class method, the Company’s unvested grants of restricted stock that contained non-forfeitable rights to dividends were treated as participating securities and were excluded from the computation of basic and diluted earnings per share. All shares of restricted stock granted since 2013 are not participating because the grant agreements contain provisions that dividends, if declared, will be forfeited if the grantee leaves the Company before the stock is vested.

For the years ended December 31, 2015, 2014 and 2013, certain common stock equivalents were excluded from the calculation of dilutive securities because their inclusion would either have been anti-dilutive or, for stock options, the exercise prices of those stock options were greater than the average market price of the Company’s common stock for the period. All of the Company’s non-participating unvested restricted shares were included in the computation of weighted average dilutive securities. The following table summarizes the shares of common stock underlying the Company’s unvested stock options and performance awards that were excluded from the calculation of dilutive securities:

### Share Repurchase Program

On July 30, 2015, the Company increased its stock repurchase program (the “Repurchase Program”) from $25.0 million to $42.5 million, and extended the term of the program through August 31, 2016. On December 10, 2015 the Company increased the Repurchase Program by $25.0 million to $67.5 million

During 2015 the Company repurchased 1,183,862 shares of common stock (at a weighted-average price of $22.84 per share) under the Repurchase Program. The total cost of $27.0 million, $26.1 million of which had settled as of December 31, 2015, was recorded as a reduction of common stock, additional paid-in capital and retained earnings in 2015. Under the Repurchase Program, all shares repurchased are retired and returned to authorized but unissued stock. The remaining availability to purchase shares under the Repurchase Program was $24.8 million as of December 31, 2015.

On February 10, 2016 the Company increased the Repurchase Program by $75.0 million to $142.5 million, amended the provisions of the plan to accelerate the pace of repurchases, and extended the program through April 30, 2017.

Earnings per share amounts for each quarter are required to be computed independently using the weighted average number of shares outstanding during the period. As a result, the sum of the individual quarterly earnings per share amounts may not agree to the earnings per share calculated for the year.

Gross profit in the fourth quarter of 2014 benefited from higher levels of claim settlements and change orders.

| Item 9. | Changes in and Disagreements With Accountants on Accounting and Financial Disclosure

None.

| Item 9A. | Controls and Procedures

### Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in the reports we file or submit pursuant to the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management, together with our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this annual report on Form 10-K. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance related to the matters stated in the above paragraph as of December 31, 2015.

### Evaluation of Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework set forth in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management’s annual report on internal control over financial reporting and the report of our independent registered public accounting firm appear in Part II, Item 8 “Financial Statements and Supplementary Data” of this Annual Report on Form 10-K.

This annual report on Form 10-K includes a report of management’s assessment regarding internal control over financial reporting (see “Management’s Report on Internal Control over Financial Reporting”) and an attestation report of our independent registered public accounting firm regarding internal control over financial reporting (see “Report of Independent Registered Public Accounting Firm”).

### Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting during the fourth quarter ended December 31, 2015 that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.

### Limitations on the Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will detect or prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
