OPERATING SEGMENTS

We operate our business through four reportable segments: Electrical Infrastructure, Oil Gas & Chemical, Storage Solutions, and Industrial.

The Electrical Infrastructure segment primarily encompasses high voltage services to investor owned utilities including construction of new substations, upgrades of existing substations, short-run transmission line installations, distribution upgrades and maintenance, and storm restoration services. We also provide construction and maintenance services to a variety of power generation facilities such as combined cycle plants, coal fired power stations, and renewable energy installations.

The Oil Gas & Chemical segment includes our traditional turnaround activities, plant maintenance services and construction in the downstream petroleum industry. Another key offering is industrial cleaning services, which include hydroblasting, hydroexcavating, chemical cleaning and vacuum services. We also perform work in the industrial and natural gas, gas processing and compression, and upstream petroleum markets.

The Storage Solutions segment includes new construction of crude and refined products aboveground storage tanks, as well as planned and emergency maintenance services. Also included in the Storage Solutions segment is work related to specialty storage tanks including liquefied natural gas ("LNG"), liquid nitrogen/liquid oxygen ("LIN/LOX"), liquid petroleum ("LPG") tanks and other specialty vessels including spheres. Finally, the Storage Solutions segment includes balance of plant work in storage terminals and tank farms.

The Industrial segment includes work in the mining and minerals industry, bulk material handling, fertilizer production facilities, as well as work for clients in other industrial and manufacturing markets.

OTHER BUSINESS MATTERS

Customers and Marketing

The Company provided services to approximately 500 customers in fiscal 2013 . One customer, Enbridge, accounted for $95.5 million, or 10.7% of our consolidated revenue, all of which was in the Storage Solutions segment. The loss of this major customer or other significant customers could have a material adverse effect on the Company; however, we are not dependent on any single contract or customer on an on-going basis.

Matrix markets its services and products primarily through its marketing and business development personnel, senior professional staff and its operating management. We competitively bid most of our projects; however, we have a number of preferred provider relationships with customers who award us work through long-term agreements. Our projects have durations ranging from a few days to over a year.

Segment Financial Information

Financial information for our operating segments is provided in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations, and in Note 13-Segment Information of the Notes to Consolidated Financial Statements included in Item 8. Financial Statements and Supplementary Data.

Competition

Our industry is highly fragmented and intensely competitive. We compete with local, regional, national and international contractors and service providers. Competitors vary with the markets we serve with few competitors competing in all of the markets we serve or in all of the services we provide. Contracts are generally awarded based on price, schedule, reputation for quality, customer satisfaction, and safety record and programs.

Backlog

We define backlog as the total dollar amount of revenues that we expect to recognize as a result of performing work that has been awarded to us through a signed contract, notice to proceed or other type of assurance that we consider firm. The following arrangements are considered firm:

For long-term maintenance contracts, we include only the amounts that we expect to recognize as revenue over the next 12 months. For all other arrangements, we calculate backlog as the estimated contract amount less revenues recognized as of the reporting date.

The following table provides a summary of changes in our backlog in fiscal 2013 :

Seasonality

Turnarounds and planned outages at customer facilities are typically scheduled in the spring and the fall when the demand for energy is lower. Quarterly operating results can exhibit seasonal fluctuations, especially in our Oil Gas & Chemical segment, for a variety of reasons. Also, we typically see a lower level of operating activity relating to construction projects during the winter months and early in the calendar year because many of our customers' capital budgets have not been finalized. Our business can also be affected, both positively and negatively, by seasonal factors such as energy demand or weather conditions including hurricanes, snowstorms, and abnormally low or high temperatures. Accordingly, results for any interim period may not necessarily be indicative of future operating results.

Material Sources and Availability

Steel plate and steel pipe are key materials used by the Company. Supplies of these materials are available throughout the United States and globally from numerous sources. We anticipate that adequate amounts of these materials will be available in the foreseeable future. However, the price, quantity, and the delivery schedules of these materials could change rapidly due to various factors, including producer capacity, the level of imports, worldwide demand, tariffs on imported steel and other market conditions.

Insurance

The Company maintains insurance coverage for various aspects of its operations. However, exposure to potential losses is retained through the use of deductibles, self-insured retentions and coverage limits.

Typically our contracts require us to indemnify our customers for injury, damage or loss arising from the performance of our services and provide warranties for materials and workmanship. The Company may also be required to name the customer as an additional insured up to the limits of insurance available, or we may be required to purchase special insurance policies or surety bonds for specific customers or provide letters of credit in lieu of bonds to satisfy performance and financial guarantees on some projects.

Matrix maintains a performance and payment bonding line sufficient to support the business. The Company generally requires its subcontractors to indemnify the Company and the Company's customer and name the Company as an additional insured for activities arising out of the subcontractors' work. We also require certain subcontractors to provide additional insurance policies, including surety bonds in favor of the Company, to secure the subcontractors' work. There can be no assurance that our insurance and the additional insurance coverage provided by our subcontractors will fully protect us against a valid claim or loss under the contracts with our customers.

Employees

As of June 30, 2013 , the Company had 3,587 employees of which 612 were employed in non-field positions and 2,975 were employed in field or shop positions. The number of employees varies significantly throughout the year because of the number, type and size of projects we have in progress at any particular time.

The Company's subsidiaries include both merit and union companies. The union businesses operate under collective bargaining agreements with various unions representing different groups of our employees. Union agreements provide union employees with benefits including health and welfare, pension, training programs and competitive compensation plans. We have not experienced any strikes or work stoppages in recent years. We maintain health and welfare, retirement and training programs for our merit employees and administrative personnel.

Patents and Proprietary Technology

Matrix Service Company's engineering subsidiary has several patents and patents pending, and continues to pursue new ideas and innovations to better serve our customers in all areas of our business. The Flex-A-Span ® and Flex-A-Seal ® trademarks are utilized to cover seals for floating roof tanks. Our patent of our ThermoStor ® diffuser system is for a process that receives, stores and dispenses both chilled and warm water in and from the same storage tank. The patented RS 1000 Tank Mixer ® controls sludge build-up in crude oil tanks through resuspension. The Valve Shield ® patent relates to a flexible fluid containment system that captures and contains fluid leaking from pipe and valve connections. The patent for Spacerless or Geocomposite Double Bottom for Storage Tanks relates to a replacement bottom with leak detection and containment that allows for the retrofitting of an existing tank while minimizing the loss of capacity. The patent for the Training Tank for Personnel Entry, Exit and Rescue relates to a mobile device that can be used to train personnel on equipment that is made to simulate real world hazards.

The Company holds a perpetual license to use various patents and technologies related to LNG storage tanks, LIN/LOX storage tanks, LPG storage tanks and thermal vacuum chambers. We believe that the ability to use these patents and technology enables us to expand our presence in the markets for these products and minimizes the development costs typically associated with organic growth.

While we believe that continued product development and the protection of our intellectual property is important to our business, we do not believe that these patents or licensed technologies are essential to our success.

Regulation

Health and Safety Regulations

Our operations are subject to regulation by the United States Occupational Safety and Health Administration ("OSHA") and Mine Safety and Health Administration ("MSHA"), and to regulation under state laws and by the Canadian Workers' Compensation Board and its Workplace Health, Safety and Compensation Commission. Regulations promulgated by these agencies require employers and independent contractors to implement work practices, medical surveillance systems and personnel protection programs to protect employees from workplace hazards and exposure to hazardous chemicals and materials. In recognition of the potential for accidents within various scopes of work, these agencies have enacted strict and

comprehensive safety regulations. The Company has established comprehensive programs for complying with health and safety regulations to protect the safety of its workers, subcontractors and customers. While the Company believes that it operates safely and prudently, there can be no assurance that accidents will not occur or that the Company will not incur substantial liability in connection with the operation of its businesses. In order to minimize the financial exposure resulting from potential accidents associated with the Company's work, the Company maintains liability insurance to limit losses that could result from our work.

Environmental

The Company's operations are subject to extensive and changing environmental laws and regulations. These laws and regulations relate primarily to air and water pollutants and the management and disposal of hazardous materials. The Company is exposed to potential liability for personal injury or property damage caused by any release, spill, exposure or other accident involving such pollutants, substances or hazardous materials.

In order to limit costs incurred as a result of environmental exposure, the Company maintains contractor's pollution liability insurance that covers liability that may be incurred as a result of accidental releases of hazardous materials.

The Company believes that it is currently in compliance, in all material aspects, with all applicable environmental laws and regulations. The Company does not expect any material charges in subsequent periods relating to environmental conditions that currently exist and does not currently foresee any significant future capital spending relating to environmental matters.

Item 1A. Risk Factors

The following risk factors should be considered with the other information included in this Annual Report on Form 10-K. As we operate in a continuously changing environment, other risk factors may emerge which could have material adverse effects on our results of operations, financial condition and cash flow.

Risk Factors Related to Our Business

Unsatisfactory safety performance may subject us to penalties, affect customer relationships, result in higher operating costs, negatively impact employee morale and result in higher employee turnover.

Workplace safety is important to the Company, our employees, and our customers. As a result, we provide comprehensive safety programs and training for all employees throughout our organization. While we focus on protecting people and property, our work is performed at construction sites and in industrial facilities and our workers are subject to the normal hazards associated with providing services at these locations. Even with proper safety precautions, these hazards can lead to personal injury, loss of life, damage to or destruction of property, plant and equipment, and environmental damage. We are intensely focused on maintaining a strong safety environment and reducing the risk of accidents to the lowest possible level.

Although we have taken what we believe are appropriate precautions to adequately train and equip our employees, we have experienced serious accidents, including fatalities, in the past and may experience additional accidents in the future. Serious accidents may subject us to penalties, civil litigation or criminal prosecution. Claims for damages to persons, including claims for bodily injury or loss of life, could result in costs and liabilities, which could materially and adversely affect our financial condition, results of operations or cash flows. Poor safety performance could also jeopardize our relationships with our customers.

Demand for our products and services is cyclical and is vulnerable to the level of capital and maintenance spending of our customers and to downturns in the industries and markets we serve, as well as conditions in the general economy.

The demand for our products and services depends upon the existence of construction and maintenance projects in the downstream petroleum, power and other heavy industries in the United States and Canada. Therefore, it is likely that our business will continue to be cyclical in nature and vulnerable to general downturns in the United States, Canadian and world economies and changes in commodity prices, which could adversely affect the demand for our products and services.

The availability of engineering and construction projects is dependent upon economic conditions in the oil, gas, and power industries, specifically, the level of capital expenditures on energy infrastructure. A prolonged period of sluggish economic conditions in North America has had and may continue to have an adverse impact on the level of capital expenditures of our customers and/or their ability to finance these expenditures. Our failure to obtain projects, the delay of project awards, the cancellation of projects or delays in the execution of contracts may result in under-utilization of our resources, which could adversely impact our revenue, operating results and cash flow. There are numerous factors beyond our control that influence the level of maintenance and capital expenditures of our customers, including:

Our results of operations depend upon the award of new contracts and the timing of those awards.

Our revenues are derived primarily from contracts awarded on a project-by-project basis. Generally, it is difficult to predict whether and when we will be awarded a new contract due to lengthy and complex bidding and selection processes, changes in existing or forecasted market conditions, access to financing, governmental regulations, permitting and environmental matters. Because our revenues are derived from contract awards, our results of operations and cash flows can fluctuate materially from period to period.

The uncertainty associated with the timing of contract awards may reduce our short-term profitability as we balance our current capacity with expectations of future contract awards. If an expected contract award is delayed or not received, we could incur costs to maintain an idle workforce that may have a material adverse effect on our results of operations. Alternatively, we may decide that our long-term interests are best served by reducing our workforce and incurring increased costs associated with severance and termination benefits, which also could have a material adverse effect on our results of operations in the period incurred. Reducing our workforce could also impact our results of operations if we are unable to adequately staff projects that are awarded subsequent to a workforce reduction.

There are integration and consolidation risks associated with our acquisition strategy. Future acquisitions may result in significant transaction expenses, and unexpected liabilities and risks associated with entering new markets. We may also be unable to profitably integrate and operate these businesses.

We may lack sufficient management, financial and other resources to successfully integrate future acquisitions, including acquisitions in markets where we have not previously operated. Any future acquisitions may result in significant transaction expenses, unexpected liabilities and other risks in addition to the integration and consolidation risks.

If we make any future acquisitions, we will likely assume liabilities of the acquired business or have exposure to contingent liabilities that may not be adequately covered by insurance or indemnification, if any, from the former owners of the acquired business. These potential liabilities could have a material adverse effect on our business.

We may need to raise additional capital in the future for working capital, capital expenditures and/or acquisitions, and we may not be able to do so on favorable terms or at all, which would impair our ability to operate our business or achieve our strategic plan.

To the extent that cash flow from operations, together with available borrowings under our credit facility, are insufficient to make future investments, acquisitions or provide needed working capital, we may require additional financing from other sources. Our ability to obtain such additional financing in the future will depend in part upon prevailing capital market conditions, as well as conditions in our business and our operating results; and those factors may affect our efforts to arrange additional financing on terms that are satisfactory to us. If adequate funds are not available, or are not available on acceptable terms, we may not be able to make future investments, take advantage of acquisitions or other opportunities, or respond to competitive challenges.

We face substantial competition in each of our business segments, which may have a material adverse effect on our business.

We face competition in all areas of our business from regional, national and international competitors. Our competitors range from small, family-owned businesses to well-established, well-financed entities, both privately and publicly held, including many major equipment manufacturers, large engineering and construction companies and specialty contractors. We

compete primarily on the basis of price, customer satisfaction, safety performance and programs, quality of our products and services, and schedule. As a result, an increase in the level of competition in one or more markets may result in lower operating margins than we have recently experienced.

Our backlog is subject to unexpected fluctuations, adjustments and cancellations and does not include the full value of our long-term maintenance contracts, and therefore, may not be a reliable indicator of our future earnings.

Backlog may not be a reliable indicator of our future performance. We cannot guarantee that the revenue projected in our backlog will be realized or profitable. Projects may remain in our backlog for an extended period of time. In addition, project cancellations or scope adjustments may occur from time to time with respect to contracts included in our backlog that could reduce the dollar amount of our backlog and the revenue and profits that we actually earn. Many of our contracts have termination rights. Therefore, project adjustments may occur from time to time to contracts in our backlog.

The loss of one or more of our significant customers could adversely affect us.

One or more customers have in the past and may in the future contribute a material portion of our revenues in any one year. Because these significant customers generally contract with us for specific projects or for specific periods of time, we may lose these customers from year to year as the projects or maintenance contracts are completed. The loss of business from any one of these customers could have a material adverse effect on our business or results of operations.

The terms of our contracts could expose us to unforeseen costs and costs not within our control, which may not be recoverable and could adversely affect our results of operations and financial condition.

A significant amount of our work is performed under fixed price contracts. Under fixed-price contracts, we agree to perform the contract for a fixed-price and, as a result, can improve our expected profit by superior execution, productivity, workplace safety and other factors resulting in cost savings. However, we could incur cost overruns above the approved contract price, which may not be recoverable. Under certain incentive fixed-price contracts, we may agree to share with a customer a portion of any savings we generate while the customer agrees to bear a portion of any increased costs we may incur up to a negotiated ceiling. To the extent costs exceed the negotiated ceiling price, we may be required to absorb some or all of the cost overruns.

Fixed-price contract prices are established based largely upon estimates and assumptions relating to project scope and specifications, personnel and productivity, material needs, and site conditions. These estimates and assumptions may prove inaccurate or conditions may change due to factors out of our control, resulting in cost overruns, which we may be required to absorb and which could have a material adverse effect on our business, financial condition and results of operations. In addition, our profits from these contracts could decrease or we could experience losses if we incur difficulties in performing the contracts or are unable to secure fixed-pricing commitments from our manufacturers, suppliers and subcontractors at the time we enter into fixed-price contracts with our customers.

Under cost-plus and time-and-material contracts, we perform our services in return for payment of our agreed upon reimbursable costs plus a profit. The profit component is typically expressed in the contract either as a percentage of the reimbursable costs we actually incur or is factored into the rates we charge for labor or for the cost of equipment and materials, if any, we are required to provide. Our profit could be negatively impacted if our actual costs exceed the estimated costs utilized to establish the billing rates included in the contracts.

We may incur significant costs in providing services in excess of original project scope without having an approved change order.

After commencement of a contract, we may perform, without the benefit of an approved change order from the customer, additional services requested by the customer that were not contemplated in our contract price for various reasons, including customer changes or incomplete or inaccurate engineering, changes in project specifications and other similar information provided to us by the customer. Our construction contracts generally require the customer to compensate us for additional work or expenses incurred under these circumstances.

A failure to obtain adequate compensation for these matters could require us to record in the current period an adjustment to revenue and profit recognized in prior periods under the percentage-of-completion accounting method. Any such adjustments, if substantial, could have a material adverse effect on our results of operations and financial condition, particularly for the period in which such adjustments are made. We can provide no assurance that we will be successful in obtaining, through negotiation, arbitration, litigation or otherwise, approved change orders in an amount adequate to compensate us for our additional work or expenses.

Our profitability could be negatively impacted if we are not able to maintain appropriate utilization of our workforce.

The extent to which we utilize our workforce affects our profitability. If we under utilize our workforce, our project gross margins and overall profitability suffer in the short-term. If we over utilize our workforce, we may negatively impact safety, employee satisfaction and project execution, which could result in a decline of future project awards. The utilization of our workforce is impacted by numerous factors including:

Our use of percentage-of-completion accounting for fixed-price contracts and our reporting of profits for cost-plus contracts prior to contract completion could result in a reduction or elimination of previously reported profits.

Our revenues are recognized using the percentage-of-completion method of accounting. Under percentage-of-completion accounting, contract revenues and earnings are recognized ratably over the contract term based on the proportion of actual costs incurred to total estimated costs. In addition, some contracts contain penalty provisions for failure to achieve certain milestones, schedules or performance standards. We review our estimates of contract revenues, costs and profitability on a monthly basis. As a result, we may adjust our estimates on one or more occasions as a result of changes in cost estimates, change orders to the original contract, or claims against the customer for increased costs incurred by us due to customer-induced delays and other factors.

If estimates of costs to complete fixed price contracts indicate a loss, a provision is made through a contract write-down for the total loss anticipated in the period the loss is determined. Contract profit estimates are also adjusted, on a percentage of completion basis, in the fiscal period in which it is determined that an adjustment is required. No restatements are made to prior periods. Further, a number of our contracts contain various cost and performance incentives and penalties that impact the earnings we realize from our contracts, and adjustments related to these incentives and penalties are recorded on a percentage of completion basis in the period when estimable and probable.

As a result of the requirements of the percentage-of-completion method of accounting, the possibility exists that we could have estimated and reported a profit on a contract over several prior periods and later determine that all or a portion of such previously estimated and reported profits were overstated. If this occurs, the full aggregate amount of the overstatement will be reported for the period in which such determination is made.

We are exposed to credit risk from customers. If we experience delays and/or defaults in customer payments, we could suffer liquidity problems or we could be unable to recover amounts owed to us.

Under the terms of our contracts, at times we commit resources to customer projects prior to receiving payments from customers in amounts sufficient to cover expenditures on these projects as they are incurred. Many of our fixed-price or cost-plus contracts require us to satisfy specified progress milestones or performance standards in order to receive a payment. Under these types of arrangements, we may incur significant costs for labor, equipment and supplies prior to receipt of payment. If the customer fails or refuses to pay us for any reason, there is no assurance we will be able to collect amounts due to us for costs previously incurred. In some cases, we may find it necessary to terminate subcontracts with suppliers engaged by us to assist in performing a contract, and we may incur costs or penalties for canceling our commitments to them. Delays in customer payments require an investment in working capital. If we are unable to collect amounts owed to us under our contracts, we may be required to record a charge against previously recognized earnings related to the project, and our liquidity, financial condition and results of operations could be adversely affected.

Actual results could differ from the estimates and assumptions that we use to prepare our financial statements.

To prepare financial statements in conformity with generally accepted accounting principles, management is required to make estimates and assumptions, as of the date of the financial statements, which affect the reported values of assets, liabilities,

revenues and expenses and disclosures of contingent assets and liabilities. Areas requiring significant estimation by our management include:

Our actual results could materially differ from these estimates.

An inability to attract and retain qualified personnel, and in particular, engineers, project managers, linemen and skilled craft workers, could impact our ability to perform on our contracts, which could harm our business and impair our future revenues and profitability.

Our ability to attract and retain qualified engineers, project managers, linemen, skilled craftsmen and other experienced professionals in accordance with our needs is an important factor in our ability to maintain profitability and grow our business. The market for these professionals is competitive, particularly during periods of economic growth when the supply is limited. We cannot provide any assurance that we will be successful in our efforts to retain or attract qualified personnel when needed. Therefore, when we anticipate or experience growing demand for our services, we may incur additional cost to maintain a professional staff in excess of our current contract needs in an effort to have sufficient qualified personnel available to address this anticipated demand. If we do incur additional compensation and benefit costs, our customer contracts may not allow us to pass through these costs.

Competent and experienced engineers, project managers, and craft workers are especially critical to the profitable performance of our contracts, particularly on our fixed-price contracts where superior design and execution of the project can result in profits greater than originally estimated or where inferior design and project execution can reduce or eliminate estimated profits or even result in a loss.

Our project managers are involved in most aspects of contracting and contract execution including:

Work stoppages and other labor problems could adversely affect us.

Some of our employees are represented by labor unions. The Company has in excess of 50 collective bargaining agreements with various labor unions. The most significant agreements include the following:

The Company is also working under a number of other collective bargaining agreements that cover a smaller number of employees. These agreements expire within the next five years. For those agreements with upcoming expiration dates, the Company is currently negotiating renewals and expects that the renewals will be successfully completed. To date, the Company has not experienced any work stoppages or other significant labor problems in connection with its collective bargaining agreements. A lengthy strike or other work stoppage on any of our projects could have a material adverse effect on our business and results of operations due to an inability to complete contracted projects in a timely manner. From time to time, we have also experienced attempts to unionize certain of our merit employees. While these efforts have only achieved limited success to date, we cannot provide any assurance that we will not experience additional and more successful union activity in the future.

We contribute to multiemployer plans that could result in liabilities to us if those plans are terminated or if we withdraw from those plans.

We contribute to several multiemployer pension plans for employees covered by collective bargaining agreements. These plans are not administered by us and contributions are determined in accordance with provisions of negotiated labor contracts. The Employee Retirement Income Security Act of 1974, as amended by the Multiemployer Pension Plan Amendments Act of 1980, imposes certain liabilities upon employers who are contributors to a multiemployer plan in the event of the employer's withdrawal from, or upon termination of, such plan. If we terminate or withdraw from a multiemployer pension plan, we could be required to make significant cash contributions to fund that plan's unfunded vested benefit, which could materially and adversely affect our financial condition and results of operations; however, we are not currently able to determine the net assets and actuarial present value of the multiemployer pension plans' unfunded vested benefits allocable to us, if any, and we are not presently aware of the amounts, if any, for which we may be contingently liable if we were to withdraw from any of these plans. In addition, if the funding level of any of these multiemployer plans becomes classified as "critical status" under the Pension Protection Act of 2006, we could be required to make significant additional contributions to those plans.

Future events, including those associated with our strategic plan, could negatively affect our liquidity position.

We can provide no assurance that we will have sufficient cash from operations or the credit capacity to meet all of our future cash needs should we encounter significant working capital requirements or incur significant acquisition costs. Insufficient cash from operations, significant working capital requirements, and contract disputes have in the past, and could in the future, reduce availability under our credit facility.

We are involved, and are likely to continue to be involved in legal proceedings, which will increase our costs and, if adversely determined, could have a material effect on our financial condition, results of operations, cash flows and liquidity.

We are currently a defendant in legal proceedings arising from the operation of our business, and it is reasonable to expect that we would be named in future actions. Many of the actions against us arise out of the normal course of performing services on project sites, and include workers' compensation claims, personal injury claims and contract disputes with our customers. From time to time, we are also named as a defendant for actions involving the violation of federal and state labor laws related to employment practices, wages and benefits. We also are, and are likely to continue to be, a plaintiff in legal proceedings against customers seeking to recover payment of contractual amounts due to us as well as claims for increased costs incurred by us resulting from, among other things, services performed by us at the request of a customer that are in excess of original project scope that are later disputed by the customer and customer-caused delays in our contract performance.

We maintain insurance against operating hazards in amounts that we believe are customary in our industry. However, our insurance policies include deductibles and certain coverage exclusions, so we cannot provide assurance that we are adequately insured against all of the risks associated with the conduct of our business. A successful claim brought against us in excess of, or outside of, our insurance coverage could have a material adverse effect on our financial condition, results of operations, cash flows and liquidity.

Litigation, regardless of its outcome, is expensive, typically diverts the efforts of our management away from operations for varying periods of time, and can disrupt or otherwise adversely impact our relationships with current or potential customers, subcontractors and suppliers. Payment and claim disputes with customers may also cause us to incur increased interest costs resulting from incurring indebtedness under our revolving line of credit or receiving less interest income resulting from fewer funds invested due to the failure to receive payment for disputed claims and accounts.

Our projects expose us to potential professional liability, product liability, warranty and other claims, which could be expensive, damage our reputation and harm our business. We may not be able to obtain or maintain adequate insurance to cover these claims.

We perform construction and maintenance services at large industrial facilities where accidents or system failures can be disastrous and costly. Any catastrophic occurrence in excess of our insurance limits at locations engineered or constructed by us or where our products are installed or services performed could result in significant professional liability, product liability, warranty and other claims against us by our customers, including claims for cost overruns and the failure of the project to meet contractually specified milestones or performance standards. Further, the rendering of our services on these projects could expose us to risks and claims by third parties and governmental agencies for personal injuries, property damage and environmental matters, among others. Any claim, regardless of its merit or eventual outcome, could result in substantial costs, divert management's attention and create negative publicity, particularly for claims relating to environmental matters where the amount of the claim could be extremely large. We may not be able to or may choose not to obtain or maintain insurance coverage for the types of claims described above. If we are unable to obtain insurance at an acceptable cost or otherwise protect against the claims described above, we will be exposed to significant liabilities, which may materially and adversely affect our financial condition and results of operations.

Employee, subcontractor or partner misconduct or our overall failure to comply with laws or regulations could harm our reputation, damage our relationships with customers, reduce our revenues and profits, and subject us to criminal and civil enforcement actions.

Misconduct, fraud, non-compliance with applicable laws and regulations, or other improper activities by one of our employees, subcontractors or partners could have a significant negative impact on our business and reputation.  Such misconduct could include the failure to comply with safety standards, laws and regulations, customer requirements, regulations pertaining to the internal controls over financial reporting, environmental laws and any other applicable laws or regulations.  The precautions we take to prevent and detect these activities may not be effective, since our internal controls are subject to inherent limitations, including human error, the possibility that controls could be circumvented or become inadequate because of changed conditions, and fraud.

Our failure to comply with applicable laws or regulations or acts of misconduct could subject us to fines and penalties, harm our reputation, damage our relationships with customers, reduce our revenues and profits and subject us to criminal and civil enforcement actions.

We rely on internally and externally developed software applications and systems to support critical functions including project management, estimating, human resources, accounting, and financial reporting. Any sudden loss, disruption or unexpected costs to maintain these systems could significantly increase our operational expense as well as disrupt the management of our business operations.

We rely on various software systems to conduct our critical operating and administrative functions.  We depend on our software vendors to provide long-term software maintenance support for our information systems.  Software vendors may decide to discontinue further development, integration or long-term software maintenance support for our information systems, in which case we may need to abandon one or more of our current information systems and migrate some or all of our project management, human resources, estimating, accounting and financial information to other systems, thus increasing our operational expense as well as disrupting the management of our business operations.

Our business may be affected by difficult work sites and environments, which may adversely affect our overall business.

We perform our work under a variety of conditions, including, but not limited to, difficult terrain, difficult site conditions and busy urban centers where delivery of materials and availability of labor may be impacted. Performing work under these conditions can slow our progress, potentially causing us to incur contractual liability to our customers. These difficult conditions may also cause us to incur additional, unanticipated costs that we might not be able to pass on to our customers.

We are susceptible to adverse weather conditions, which may harm our business and financial results.

Our business may be adversely affected by severe weather in areas where we have significant operations. Repercussions of severe weather conditions may include:

Environmental factors and changes in laws and regulations could increase our costs and liabilities.

Our operations are subject to environmental laws and regulations, including those concerning emissions into the air; discharges into waterways; generation, storage, handling, treatment and disposal of hazardous material and wastes; and health and safety.

Our projects often involve highly regulated materials, including hazardous wastes. Environmental laws and regulations generally impose limitations and standards for regulated materials and require us to obtain permits and comply with various other requirements. The improper characterization, handling, or disposal of regulated materials or any other failure by us to comply with federal, state and local environmental laws and regulations or associated environmental permits could subject us to the assessment of administrative, civil and criminal penalties, the imposition of investigatory or remedial obligations, or the issuance of injunctions that could restrict or prevent our ability to operate our business and complete contracted projects.

In addition, under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), and comparable state laws, we may be required to investigate and remediate regulated materials. CERCLA and the comparable state laws typically impose liability without regard to whether a company knew of or caused the release, and liability for the entire cost of clean-up can be imposed upon any responsible party.

We are subject to numerous other laws and regulations including those related to business registrations and licenses, environment, workplace, employment, health and safety. These laws and regulations are complex, change frequently and could become more stringent in the future. It is impossible to predict the effect on us of any future changes to these laws and regulations. We can provide no absolute assurance that our operations will continue to comply with future laws and regulations or that the costs to comply with these laws and regulations and/or a failure to comply with these laws will not significantly adversely affect our business, financial condition and results of operations.

We recorded an intangible asset impairment charge of $0.3 million in fiscal 2013 related to an acquisition. Earnings for future periods may be affected by additional impairment charges.

Because we have grown in part through acquisitions, goodwill and other acquired intangible assets represent a substantial portion of our assets. We perform annual goodwill and intangible asset impairment reviews in the fourth quarter of every fiscal year. In addition, we perform an impairment review whenever events or changes in circumstances indicate the carrying value of goodwill or an intangible or fixed asset may not be recoverable. At some future date, we may determine that significant impairment has occurred, which could require us to write off an additional portion of our assets and could adversely affect our financial condition or results of operations.

Our credit facility imposes restrictions that may limit business alternatives.

Our credit facility contains covenants that restrict or limit our ability to incur additional debt, acquire or dispose of assets, repurchase equity, or make certain distributions, including dividends. In addition, our credit facility requires that we comply with a number of financial covenants. These covenants and restrictions may impact our ability to effectively execute operating and strategic plans and our operating performance may not be sufficient to comply with the required covenants.

Our failure to comply with one or more of the covenants in our credit facility could result in an event of default. We can provide no assurance that a default could be remedied, or that our creditors would grant a waiver or amend the terms of the credit facility. If an event of default occurs, our lenders could elect to declare all amounts outstanding under the facility to be immediately due and payable, terminate all commitments, refuse to extend further credit, and require us to provide cash to collateralize any outstanding letters of credit. If an event of default occurs and the lenders under the credit facility accelerate the maturity of any loans or other debt outstanding, we may not have sufficient liquidity to repay amounts outstanding under the existing agreement.

Risk Factors Related to Our Common Stock

Our common stock, which is listed on the NASDAQ Global Select Market, has experienced significant price and volume fluctuations. These fluctuations are likely to continue in the future, and our stockholders may not be able to resell their shares of common stock at or above the purchase price paid.

The market price of our common stock may change significantly in response to various factors and events beyond our control, including the following:

Some companies that have volatile market prices for their securities have been subject to security class action suits filed against them. If a suit were to be filed against us, regardless of the outcome, it could result in substantial costs and a diversion of our management's attention and resources. This could have a material adverse effect on our business, results of operations and financial condition.

Future sales of our common stock may depress our stock price.

Sales of a substantial number of shares of our common stock in the public market or otherwise, either by us, a member of management or a major stockholder, or the perception that these sales could occur, could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities.

We may issue additional equity securities, which could lead to dilution of our issued and outstanding stock.

The issuance of additional common stock, restricted stock units or securities convertible into our common stock could result in dilution of the ownership interest held by existing stockholders. We are authorized to issue, without stockholder approval 5,000,000 shares of preferred stock, par value $0.01 per share, in one or more series, which may give other stockholders dividend, conversion, voting, and liquidation rights, among other rights, which may be superior to the rights of holders of our common stock. In addition, we are authorized to issue, without stockholder approval, a significant number of additional shares of our common stock and securities convertible into either common stock or preferred stock.

Item 2. Properties

In addition to the locations listed above, Matrix has temporary office facilities at numerous customer locations throughout the United States and Canada. 

Item 3. Legal Proceedings

We are a party to a number of legal proceedings. We believe that the nature and number of these proceedings are typical for a company of our size engaged in our type of business and that none of these proceedings will result in a material effect on our business, results of operations, financial condition, cash flows or liquidity. 

Item 4. Mine Safety Disclosures

Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") requires domestic mine operators to disclose violations and orders issued under the Federal Mine Safety and Health Act of 1977 (the "Mine Act") by the federal Mine Safety and Health Administration. We do not act as owner of any mines, but as a result of our performing services or construction at mine sites as an independent contractor, we may be considered an "operator" within the meaning of the Mine Act.

There were no mine safety violations or other regulatory matters required to be disclosed in this Annual Report under Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Management's discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). GAAP represents a comprehensive set of accounting and disclosure rules and requirements, the application of which requires management judgments and estimates including, in certain circumstances, choices between acceptable GAAP alternatives. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, if any, at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from these estimates under different assumptions or conditions. Note 1- Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements included in Part II, Item 8 - Financial Statements and Supplementary Data in this Annual Report on Form 10-K, contains a comprehensive summary of our significant accounting policies. The following is a discussion of our most critical accounting policies, estimates, judgments and uncertainties that are inherent in our application of GAAP.

CRITICAL ACCOUNTING ESTIMATES

Revenue Recognition

Matrix records profits on fixed-price contracts on a percentage-of-completion basis, primarily based on costs incurred to date compared to the total estimated cost. The Company records revenue on cost-plus and time-and-material contracts on a proportional performance basis as costs are incurred. Contracts in process are valued at cost plus accrued profits less billings on uncompleted contracts. Contracts are generally considered substantially complete when field construction is completed. The elapsed time from award of a contract to completion of performance may be in excess of one year. Matrix includes pass-through revenue and costs on cost-plus contracts, which are customer-reimbursable materials, equipment and subcontractor costs, when Matrix determines that it is responsible for the procurement and management of such cost components.

Matrix has numerous contracts that are in various stages of completion, which require estimates to determine the appropriate cost and revenue recognition. The Company has a history of making reasonably dependable estimates of the extent of progress towards completion, contract revenues and contract costs, and accordingly, does not believe significant fluctuations are likely to materialize. However, current estimates may be revised as additional information becomes available. If estimates of costs to complete fixed-price contracts indicate a loss, a provision is made through a contract write-down for the total loss anticipated. A number of our contracts contain various cost and performance incentives and penalties that impact the earnings we realize from our contracts. Adjustments related to these incentives and penalties are recorded in the period on a percentage of completion basis when estimable and probable.

Indirect costs, such as salaries and benefits, supplies and tools, equipment costs and insurance costs, are charged to projects based upon direct labor hours and overhead allocation rates per direct labor hour. Warranty costs are normally incurred prior to project completion and are charged to project costs as they are incurred. Warranty costs incurred subsequent to project completion were not material for the periods presented. Overhead allocation rates are established annually during the budgeting process and evaluated for accuracy throughout the year based upon actual direct labor hours and actual costs incurred.

Change Orders and Claims

Change orders are modifications of an original contract that effectively change the existing provisions of the contract. Change orders may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Matrix or our clients may initiate change orders. The client's agreement to the terms of change orders is, in many cases, reached prior to work commencing; however, sometimes circumstances require that work progress prior to obtaining client agreement. Costs related to change orders are recognized as incurred. Revenues attributable to change orders that are unapproved as to price or scope are recognized to the extent that costs have been incurred if the amounts can be reliably estimated and their realization is probable. Revenues in excess of the costs attributable to change orders that are unapproved as to price or scope are recognized only when realization is assured beyond a reasonable doubt. Change orders that are unapproved as to both price and scope are evaluated as claims.

Claims are amounts in excess of the agreed contract price that we seek to collect from customers or others for delays, errors in specifications and designs, contract terminations, change orders in dispute or unapproved as to both scope and price or other causes of anticipated additional costs incurred by us. Recognition of amounts as additional contract revenue related to

claims is appropriate only if it is probable that the claims will result in additional contract revenue and if the amount can be reliably estimated. We must determine if:

If all of the these requirements are met, revenue from a claim is recorded only to the extent that we have incurred costs relating to the claim.

As of June 30, 2013 and June 30, 2012 , costs and estimated earnings in excess of billings on uncompleted contracts included revenues for unapproved change orders and claims of $9.1 million and $8.5 million, respectively. Historically, our collections for unapproved change orders and claims have approximated the amount of revenue recognized.

Loss Contingencies

Various legal actions, claims, and other contingencies arise in the normal course of our business. Contingencies are recorded in the consolidated financial statements, or are otherwise disclosed, in accordance with ASC 450-20, "Loss Contingencies". Specific reserves are provided for loss contingencies to the extent we conclude that a loss is both probable and estimable. We use a case-by-case evaluation of the underlying data and update our evaluation as further information becomes known. We believe that any amounts exceeding our recorded accruals should not materially affect our financial position, results of operations or liquidity. However, the results of litigation are inherently unpredictable and the possibility exists that the ultimate resolution of one or more of these matters could result in a material effect on our financial position, results of operations or liquidity.

Legal costs are expensed as incurred.

Insurance Reserves

We maintain insurance coverage for various aspects of our operations. However, we retain exposure to potential losses through the use of deductibles, coverage limits and self-insured retentions. We establish reserves for claims using a combination of actuarially determined estimates and management judgment on a case-by-case basis and update our evaluations as further information becomes known. Judgments and assumptions, including the assumed losses for claims incurred but not reported, are inherent in our reserve accruals; as a result, changes in assumptions or claims experience could result in changes to these estimates in the future. If actual results of claim settlements are different than the amounts estimated we may be exposed to gains or losses that could be significant. A hypothetical ten percent unfavorable change in our claim reserves at June 30, 2013 would have reduced fiscal 2013 pretax income by $0.5 million.

Goodwill

Goodwill represents the excess of the purchase price of acquisitions over the acquisition date fair value of the net identifiable tangible and intangible assets acquired. In accordance with current accounting guidance, goodwill is not amortized and is tested at least annually for impairment at the reporting unit level.

We perform our annual analysis during the fourth quarter of each fiscal year and in any other period in which indicators of impairment warrant additional analysis. Goodwill impairment reviews involve a two step process. Goodwill is first evaluated for impairment by comparing management's estimate of the fair value of a reporting unit with its carrying value, including goodwill.

Management utilizes a discounted cash flow analysis, referred to as an income approach, to determine the estimated fair value of our reporting units. Significant judgments and assumptions including the discount rate, anticipated revenue growth rate and gross margins, estimated operating and interest expense, and capital expenditures are inherent in these fair value estimates, which are based on our operating and capital budgets and on our strategic plan. As a result, actual results may differ from the estimates utilized in our income approach. The use of alternate judgments and/or assumptions could result in a fair value that differs from our estimate and could result in the recognition of an impairment charge in the financial statements. As a result of these uncertainties, we utilize multiple scenarios and assign probabilities to each of the scenarios in the income approach.

We also consider market-based approaches to assess the fair value of our reporting units. We compare market multiples from our public peer companies in the engineering and construction industry, as well as the combined carrying values of our reporting units with market capitalization.

If the carrying value of our reporting unit is higher than its fair value, there is an indication that impairment may exist and the second step must be performed to measure the amount of impairment. The amount of impairment is determined by comparing the implied fair value of the reporting unit's goodwill to the carrying value of the goodwill calculated in the same manner as if the reporting unit were being acquired in a business combination. If the implied fair value of goodwill is less than its carrying value, we would record an impairment charge for the difference.

Although we do not anticipate a future impairment charge, certain events could occur that would adversely affect the reported value of goodwill. Such events could include, but are not limited to, a change in economic or competitive conditions, a significant change in the project plans of our customers, a deterioration in the economic condition of the customers and industries we serve, and a material negative change in the relationships with one or more of our significant customers. If our judgments and assumptions change as a result of the occurrence of any of these events or other events that we do not currently anticipate, our expectations as to future results and our estimate of the implied value of one or more of our reporting units also may change.

We performed our annual impairment test in the fourth quarter to determine whether an impairment existed and to determine the amount of headroom. We define "headroom" as the percentage difference between the fair value of a reporting unit and its carrying value. The amount of headroom varies by reporting unit. Approximately 39% of our goodwill balance is attributable to one reporting unit. This unit had headroom of 64%. We have four additional reporting units with goodwill representing 19%, 13%, 10% and 10% of the total goodwill balance with headroom of 224%, 144%, 149% and 123%, respectively.

Our significant assumptions, including revenue growth rates, gross margins, unanticipated operating and interest expense and other factors may change in light of changes in the economic and competitive environment in which we operate. Assuming that all other components of our fair value estimate remain unchanged, a change in the following assumptions would have the following effect on headroom:

Other Intangible Assets

Intangible assets that have finite useful lives are amortized by the straight-line method over their useful lives ranging from 1 to 15 years. Intangible assets that have indefinite useful lives are not amortized but are tested at least annually for impairment. Each reporting period, we evaluate the remaining useful lives of intangible assets not being amortized to determine whether facts and circumstances continue to support an indefinite useful life and review both amortizing and non-amortizing intangible assets for impairment indicators. In fiscal 2013, we reclassified an intangible asset from an indefinite-lived intangible to a finite-lived intangible resulting in an impairment charge of $0.3 million.

Recently Issued Accounting Standards

Accounting Standards Update 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income

In February 2013, the FASB issued Accounting Standards Update No. 2013-02,"Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" (ASU 2013-02). ASU 2013-02 requires companies to report the effect of significant reclassifications out of accumulated other comprehensive income, by component, either on the face of the financial statements or in the notes to the financial statements and is intended to help entities improve the transparency of changes in other comprehensive income. ASU 2013-02 does not amend any existing

requirements for reporting net income or other comprehensive income in the financial statements. ASU 2013-02 is effective for reporting periods beginning after December 15, 2012. We currently do not expect the adoption of this standard to have a material impact on our consolidated financial statements.

Accounting Standards Update 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities

In December 2011, the FASB issued Accounting Standards Update No. 2011-11,"Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities" (ASU 2011-11) and in January 2013, the FASB issued Accounting Standards Update No. 2013-01, "Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities." ASU 2011-11, as clarified, enhances disclosures surrounding offsetting (netting) assets and liabilities. The standard applies to derivatives, repurchase

agreements and securities lending transactions and requires companies to disclose gross and net information about financial

instruments and derivatives eligible for offset and to disclose financial instruments and derivatives subject to master netting

arrangements in financial statements. ASU 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013. We will adopt this standard beginning our first interim period of fiscal 2014. We currently do not expect the adoption of this standard to have a material impact on our consolidated financial statements.

Results of Operations

Overview

We operate our business through four reportable segments: Electrical Infrastructure, Oil Gas & Chemical, Storage Solutions, and Industrial:

The Electrical Infrastructure segment primarily encompasses high voltage services to investor owned utilities, including construction of new substations, upgrades of existing substations, short-run transmission line installations, distribution upgrades and maintenance, and storm restoration services. We also provide construction and maintenance services to a variety of power generation facilities such as combined cycle plants, coal fired power stations, and renewable energy installations.

The Oil Gas & Chemical segment includes our traditional turnaround activities, plant maintenance services and construction in the downstream petroleum industry. Another key offering is industrial cleaning services, which include hydroblasting, hydroexcavating, chemical cleaning, and vacuum services. We also perform work in the industrial and natural gas, gas processing and compression, and upstream petroleum markets.

The Storage Solutions segment includes new construction of crude and refined products aboveground storage tanks, as well as planned and emergency maintenance services. Also included in the Storage Solutions segment is work related to specialty storage tanks including LNG, LIN/LOX, and LPG tanks and other specialty vessels including spheres. Finally, the Storage Solutions segment includes balance of plant work in storage terminals and tank farms.

The Industrial segment includes work in the mining and minerals industry, bulk material handling, fertilizer production facilities, as well as work for clients in other industrial markets.

The majority of the work for all segments is performed in the United States, with 8.7% of revenues generated in Canada during fiscal 2013 , 8.5% in fiscal 2012 and 4.8% in fiscal 2011. Significant period to period changes in revenues, gross profits and operating results are discussed below on a consolidated basis and for each segment.

Results of Operations

(In thousands)

Fiscal 2013 Versus Fiscal 2012

Consolidated

Consolidated revenues were $892.6 million in fiscal 2013, an increase of $153.6 million, or 20.8%, from consolidated revenues of $739.0 million in fiscal 2012. The increase in consolidated revenues was a result of increases in all four segments: Oil Gas & Chemical, Electrical Infrastructure, Industrial and Storage Solutions which increased $68.0 million, $36.1 million, $34.3 million and $15.0 million, respectively.

Consolidated gross profit increased from $79.6 million in fiscal 2012 to $94.7 million in fiscal 2013. The increase of $15.1 million, or 19.0%, was due to higher revenues, partially offset by lower gross margins which decreased to 10.6% in fiscal 2013 compared to 10.8% a year earlier.

Consolidated SG&A expenses were $58.0 million in fiscal 2013 compared to $48.0 million in the same period a year earlier. The increase of $10.0 million, or 20.8%, was primarily related to our planned investments in the branding initiative, strategic growth areas and related support functions coupled with a higher business volume. The Company also incurred a bad debt charge of $0.7 million in fiscal 2013. SG&A expense as a percentage of revenue was 6.5% in both fiscal 2013 and fiscal 2012.

Net interest expense was $0.8 million in both fiscal 2013 and fiscal 2012.

The effective tax rates for fiscal 2013 and fiscal 2012 were 33.2% and 43.6%, respectively. The current year effective tax rate was positively impacted by the effect of retroactive tax legislation enacted in the third quarter of fiscal 2013 and a change in estimate related to an available tax credit. The fiscal 2012 effective tax rate was higher than the statutory rate due to cumulative non-deductible expenses totaling $3.1 million related to deductibility limitations applying to certain items that had previously been fully deducted, of which $2.1 million was related to prior fiscal years (fiscal 2009 to fiscal 2011). The fiscal 2012 effective tax rate was positively impacted by the release of a valuation allowance on foreign tax credit carryovers of $0.5 million.

Electrical Infrastructure

Revenues for the Electrical Infrastructure segment increased $36.1 million, or 26.7%, to $171.2 million in fiscal 2013 compared to $135.1 million in the same period a year earlier. The higher revenue was primarily due to an increase in high voltage work related primarily to storm restoration services and higher transmission and distribution work in the Northeast United States. Gross margins were 12.7% in fiscal 2013 compared to 12.3% in fiscal 2012. The improvement in gross margins in fiscal 2013 is due to higher margins related to storm restoration work and the improved recovery of overhead costs caused by a higher business volume, partially offset by lower direct margins related to other electrical work.

Oil Gas & Chemical

Revenues for the Oil Gas & Chemical segment increased to $273.8 million in fiscal 2013 compared to $205.8 million in the same period a year earlier. The increase of $68.0 million, or 33.0%, was primarily due to a higher level of turnaround work, geographic expansion of turnaround services, and capital construction projects. Gross margins were 12.0% in fiscal 2013 compared to 9.8% in fiscal 2012. The improvement in gross margins is primarily due to the favorable effect of the improved recovery of overhead costs caused by a higher business volume and improved project execution.

Storage Solutions

Revenues for the Storage Solutions segment increased to $393.2 million in fiscal 2013 compared to $378.2 million in the same period a year earlier. The increase of $15.0 million, or 4.0%, was primarily due to higher levels of work in Canada in our aboveground storage tank business. Gross margins decreased from 11.2% in fiscal 2012 to 9.5% in the same period in the current year. The lower margins in fiscal 2013 was primarily due to unrecovered overhead costs, a legal charge of $1.0 million and lower direct margins caused primarily by a $3.7 million charge on one project. The legal charge is discussed under the heading "Legal Settlement" and the project charge is discussed under the heading "Western Canada Aboveground Storage Tank Project" in Note 3 of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Report on Form 10-K.

Industrial

Revenues for the Industrial segment totaled $54.3 million in fiscal 2013 compared to $20.0 million in the same period a year earlier. The increase of $34.3 million, or 172.0%, was primarily due to higher revenues in our mining and minerals

business. Gross margins were 4.8% in fiscal 2013 compared to 2.4% in fiscal 2012. Although negatively impacted by lower than anticipated business ramp up, gross margins improved throughout fiscal 2013 as the volume of business increased. We also incurred a $0.4 million project charge in fiscal 2013 for this segment. Fiscal 2012 and fiscal 2013 margins were negatively impacted by startup costs related to entry into the bulk material handling and mining and minerals markets.

Fiscal 2012 Versus Fiscal 2011

Consolidated

Consolidated revenues were $739.0 million in fiscal 2012, an increase of $111.9 million, or 17.8%, from consolidated revenues of $627.1 million in fiscal 2011. The increase in consolidated revenues was a result of increases in Storage Solutions and Oil Gas & Chemical revenues, which increased $79.4 million and $62.5 million, respectively. These increases in revenues were partially offset by lower Electrical Infrastructure and Industrial revenues, which decreased $16.0 million and $14.0 million, respectively.

Consolidated gross profit increased from $74.9 million in fiscal 2011 to $79.6 million in fiscal 2012. The increase of $4.7 million was primarily due to higher revenues, partially offset by a decrease in gross margins from 11.9% in fiscal 2011 to 10.8% in fiscal 2012.

Consolidated SG&A expenses were $48.0 million in fiscal 2012 compared to $44.0 million in fiscal 2011. The increase of $4.0 million, or 9.1%, was primarily due to higher operating costs in fiscal 2012 related to increased business volumes, costs related to our investment in high growth areas of the business and related investment in support functions such as safety, marketing, corporate development, systems and training, and a non-routine stock compensation charge, partially offset by lower legal costs. SG&A expense as a percentage of revenue decreased to 6.5% in fiscal 2012 compared to 7.0% in fiscal 2011.

Net interest expense was $0.8 million in fiscal 2012 and $0.7 million in fiscal 2011.

Other expense in fiscal 2012 was $0.4 million and related primarily to foreign currency transaction losses. Fiscal 2011 had other income of $0.4 million, which related primarily to foreign currency transaction gains.

The effective tax rates for fiscal 2012 and fiscal 2011 were 43.6% and 38.0%, respectively. The fiscal 2012 effective tax rate was higher than the statutory rate due to cumulative non-deductible expenses totaling $3.1 million related to deductibility limitations applying to certain items that had previously been fully deducted, of which $2.1 million was related to prior fiscal years (fiscal 2009 to fiscal 2011) and $1.0 million was for the current fiscal year. The fiscal 2012 effective tax rate was positively impacted by the release of a valuation allowance on foreign tax credit carryovers of $0.5 million.

Electrical Infrastructure

Revenues for the Electrical Infrastructure segment decreased from $151.1 million in fiscal 2011 to $135.1 million in fiscal 2012. The decrease of $16.0 million, or 10.6%, was primarily due to the completion of a cogeneration project in the prior year and unfavorable conditions in our east coast operations related to a decline in spending by electric utilities due to warm winter weather, the impact of low natural gas prices, as well as timing delays of various project start dates and contract awards. Gross margins were 12.3% in fiscal 2012 compared to 12.1% in fiscal 2011.

Oil Gas & Chemical

Revenues for the Oil Gas & Chemical segment increased to $205.8 million in fiscal 2012 compared to $143.4 million in fiscal 2011. The increase of $62.4 million, or 43.5%, was due to a significantly higher volume of turnaround work and a higher level of capital construction projects. Gross margins were 9.8% in fiscal 2012 compared to 9.5% in fiscal 2011.

Storage Solutions

Revenues for the Storage Solutions segment increased to $378.2 million in fiscal 2012 compared to $298.7 million in fiscal 2011. The increase of $79.5 million, or 26.6%, was due to higher levels of work both domestically and in Canada in our core aboveground storage tank business and an increase in domestic tank farm and terminal balance of plant work. Gross margins decreased from 13.0% in fiscal 2011 to 11.2% in fiscal 2012. The lower margins in fiscal 2012 were primarily due to geographic expansion, costs associated with unexpected warranty work, and isolated margin fades.

Industrial

Revenues for the Industrial segment decreased from $33.9 million in fiscal 2011 to $20.0 million in fiscal 2012. The decrease of $13.9 million, or 41.0%, was largely due to the timing of revenues on a single project in 2011. This project accounted for $10.8 million of revenues in fiscal 2011 and $2.4 million in fiscal 2012. Gross margins decreased from 12.2% in fiscal 2011 to 2.4% in the current year. Gross margins in fiscal 2012 were negatively impacted by startup costs related to our entry into the bulk material handling and mining and minerals markets.

Non-GAAP Financial Measure

EBITDA is a supplemental, non-GAAP financial measure. EBITDA is defined as earnings before interest expense, income taxes, depreciation and amortization. We have presented EBITDA because it is used by the financial community as a method of measuring our performance and of evaluating the market value of companies considered to be in similar businesses. We believe that the line item on our Consolidated Statements of Income entitled "Net Income" is the most directly comparable GAAP measure to EBITDA. Since EBITDA is not a measure of performance calculated in accordance with GAAP, it should not be considered in isolation of, or as a substitute for, net earnings as an indicator of operating performance. EBITDA, as we calculate it, may not be comparable to similarly titled measures employed by other companies. In addition, this measure is not necessarily a measure of our ability to fund our cash needs. As EBITDA excludes certain financial information compared with net income, the most directly comparable GAAP financial measure, users of this financial information should consider the type of events and transactions that are excluded. Our non-GAAP performance measure, EBITDA, has certain material limitations as follows:

A reconciliation of EBITDA to net income follows:

FINANCIAL CONDITION AND LIQUIDITY

Overview

We define liquidity as the ability to pay our liabilities as they become due, fund business operations and meet all contractual or financial obligations. Our primary sources of liquidity in fiscal 2013 were cash on hand at the beginning of the year, capacity under our credit facility, and cash generated from operations. Cash on hand at June 30, 2013 totaled $63.8 million and availability under the credit facility totaled $111.6 million , resulting in total liquidity of $175.4 million . We expect to fund our operations for the next twelve months through the use of cash generated from operations, existing cash balances and borrowings under our credit facility, as necessary.

Factors that routinely impact our short-term liquidity and that may impact our long-term liquidity include, but are not limited to:

Other factors that may impact both short and long-term liquidity include:

We have an effective shelf registration statement on file with the SEC under which we may issue, from time to time, up to $400 million of senior debt securities, subordinated debt securities, common stock, preferred stock and warrants. This shelf gives us additional flexibility, when capital market conditions are favorable, to grow our business, finance acquisitions or to optimize our balance sheet in order to improve or maintain our financial flexibility. We may also elect to issue term debt or increase the amount of our credit facility.

Cash Flows Provided by Operating Activities

Cash flows provided by operating activities for the twelve months ended June 30, 2013 totaled $57.1 million . Major components of cash flows from operating activities for the year ending June 30, 2013 are as follows:

The cash effect of significant changes in operating assets and liabilities include the following:

Cash Flows Used for Investing Activities

Investing activities used $32.4 million of cash in the twelve months ended June 30, 2013 due to capital expenditures of $23.2 million and the purchase of certain assets of Pelichem in the amount of $9.4 million as discussed in Note 2 - Acquisitions, partially offset by proceeds from asset dispositions of $0.2 million. Capital expenditures included $12.9 million for the purchase of construction equipment, $6.1 million for transportation equipment, $3.8 million for office equipment and software and $0.4 million for land and buildings.

Cash Flows Used for Financing Activities

Financing activities used $0.2 million of cash in the twelve months ended June 30, 2013 primarily due to treasury share purchases of $1.2 million, offset in part by proceeds recived from stock issuances of $0.9 million. Borrowings during fiscal 2013 were limited to Canadian dollar advances under our Credit Agreement to mitigate foreign exchange rate risks related to cross-border purchases of materials and services.

Senior Revolving Credit Facility

The Company has a five-year, $125.0 million senior secured revolving credit facility (the "Credit Agreement") that expires November 7, 2016. Advances under the Credit Agreement may be used for working capital, issuance of letters of credit and other lawful corporate purposes.

The credit agreement includes the following covenants and borrowing limitations:

Amounts borrowed under the credit facility bear interest at LIBOR or an Alternate Base Rate, plus in each case, an additional margin based on the Senior Leverage Ratio. The Credit Agreement includes additional margin ranges on Alternate Base Rate loans between 0.75% and 1.5% and between 1.75% and 2.5% on LIBOR-based loans.

The Credit Agreement also permits us to borrow in Canadian dollars with a sublimit of U.S. $15.0 million. Amounts borrowed in Canadian dollars will bear interest either at the CDOR Rate, plus an additional margin based on the Senior Leverage Ratio ranging from 1.75% to 2.5%, or at the Canadian Prime Rate, plus an additional margin based on the Senior Leverage Ratio ranging from 2.25% to 3.0%. The CDOR Rate is equal to the sum of the annual rate of interest which is the rate determined as being the arithmetic average of the quotations of all institutions listed in respect of the relevant CDOR interest period for Canadian Dollar denominated bankers' acceptances, plus 0.1%. The Canadian Prime Rate is equal to the greater of (i) the rate of interest per annum most recently announced or established by JPMorgan Chase Bank, N.A., Toronto Branch as its reference rate in effect on such day for determining interest rates for Canadian Dollar denominated commercial loans in Canada and (ii) the CDOR Rate plus 1.0%.

The Unused Revolving Credit Facility Fee is between 0.30% and 0.45% based on the Senior Leverage Ratio.

The Credit Agreement includes a Senior Leverage Ratio covenant, which provides that Consolidated Funded Indebtedness may not exceed 2.5 times Consolidated EBITDA, as defined in the Credit Agreement, over the previous four quarters. For the four quarters ended June 30, 2013 , Consolidated EBITDA, as defined in the Credit Agreement, was $53.3 million . Accordingly, at June 30, 2013 , the Company had full availability of the $125.0 million credit facility. Consolidated Funded Indebtedness at June 30, 2013 was $6.6 million .

Availability under the credit facility is as follows:

The Company is in compliance with all affirmative, negative, and financial covenants under the Credit Agreement and is at the lowest margin tier for the LIBOR, Alternate Base Rate, CDOR and Canadian Prime Rate loans and the lowest tier for the Unused Revolving Credit Facility Fee.

Dividend Policy

We have never paid cash dividends on our common stock, and the terms of our Credit Agreement limit the amount of cash dividends we can pay. Under our Credit Agreement, we may declare and pay dividends on our capital stock during any fiscal year up to an amount which, when added to all other dividends paid during such fiscal year, does not exceed 50% of our cumulative net income for such fiscal year to such date. While we currently do not intend to pay cash dividends, any future dividend payments will depend on our financial condition, capital requirements and earnings as well as other relevant factors.

Treasury Shares

On November 6, 2012, our Board of Directors approved an extension of a stock buyback program that allows the Company to purchase up to 2,113,497 shares provided that such purchases do not exceed $25.0 million in any calendar year through the end of calendar year 2014 if sufficient liquidity exists and we believe that it is in the best interest of the stockholders. The Company may elect to purchase shares under this program.

In addition to the stock buyback program, the Company may withhold shares of common stock to satisfy the tax withholding obligations upon vesting of an employee's deferred shares. Matrix withheld 107,344 shares during fiscal 2013 to satisfy these obligations. These shares were returned to the Company's pool of treasury shares.

The Company has 1,779,593 treasury shares as of June 30, 2013 and intends to utilize these treasury shares solely in connection with equity awards under the Company's stock incentive plans.

Commitments and Off-Balance Sheet Arrangements

As of June 30, 2013 , the following commitments and off-balance sheet arrangements were in place to support our ordinary course obligations:

Contractual obligations at June 30, 2013 are summarized below:

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

Our interest rate risk results primarily from our variable rate indebtedness under our credit facility, which is influenced by movements in short-term rates. Borrowings under our $125.0 million revolving credit facility are based on an Alternate Base Rate, LIBOR, CDOR or Canadian Prime Rate as elected by the Company plus an additional margin based on our Senior Leverage Ratio. Although there were no amounts outstanding under the facility at June 30, 2013 , we sometimes borrow against our revolving credit line to fund short-term working capital needs, and we may borrow in the future.

Financial instruments with interest rate risk at June 30, 2013 were as follows:

Financial instruments with interest rate risk at June 30, 2012 were as follows:

Foreign Currency Risk

Matrix Service Company has subsidiaries with operations in Canada with the Canadian dollar as their functional currency. Historically, movements in the foreign currency exchange rate have not significantly impacted results. However, further growth in our Canadian operations and significant fluctuations in the Canadian Dollar/U.S. Dollar exchange rate could impact the Company's financial results in the future. Management has not entered into derivative instruments to hedge foreign currency risk, but periodically evaluates the materiality of our foreign currency exposure. To mitigate our risk, on occasion we borrow Canadian dollars under our credit facility to settle U.S. dollar account balances. A 10% unfavorable change in the Canadian dollar against the U. S. dollar would not have had a material impact on the financial results of the Company for the fiscal year ended June 30, 2013 .

Commodity Price Risk

The Company has no direct commodity exposure, but we do have exposure to materials derived from certain commodities including steel plate and steel pipe, which are key materials used by the Company. Supplies of these materials are available throughout the United States and worldwide. We anticipate that adequate amounts of these materials will be available in the foreseeable future. However, the price, quantity, and delivery schedules of these materials could change rapidly due to various factors, including producer capacity, the level of foreign imports, worldwide demand, the imposition or removal of tariffs on imported steel and other market conditions. We mitigate these risks primarily by procuring materials upon contract execution to ensure that our purchase price approximates the costs included in the project estimate.

Item 8. Financial Statements and Supplementary Data

Financial Statement Schedules

The financial statement schedule is filed as a part of this report under Schedule II – Valuation and Qualifying Accounts for the three fiscal years ended June 30, 2013 ,  June 30, 2012 and June 30, 2011 immediately following Quarterly Financial Data (Unaudited). All other schedules are omitted because they are not applicable or the required information is shown in the financial statements, or notes thereto, included herein.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Matrix Service Company (the "Company") and its wholly-owned subsidiaries are responsible for establishing and maintaining adequate internal control over financial reporting. The 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 U.S. generally accepted accounting principles. Internal control over financial reporting includes 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. 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 (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.

All internal control systems, no matter how well designed, have inherent limitations and cannot provide absolute assurance that all objectives will be met. Internal control over financial reporting is a process that involves diligence and is subject to lapses in judgment and human error. Internal control over financial reporting can also be circumvented by collusion or management override of controls. Because of these limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis.

The Company's management assessed the effectiveness of the Company's internal control over financial reporting as of June 30, 2013 . In making this assessment, the Company's management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control-Integrated Framework.

Management's assessment included an evaluation of such elements as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, overall control environment and information systems control environment. Based on this assessment, the Company's management has concluded that the Company's internal control over financial reporting as of June 30, 2013 was effective.

Deloitte & Touche LLP, an independent registered public accounting firm, has issued an attestation report on the effectiveness of the Company's internal control over financial reporting as of June 30, 2013 . Deloitte & Touche LLP's report on the Company's internal control over financial reporting is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Matrix Service Company:

We have audited the internal control over financial reporting of Matrix Service Company and subsidiaries ("the Company") as of June 30, 2013 based on criteria established in Internal Control-Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company'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 by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the 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, the Company maintained, in all material respects, effective internal control over financial reporting as of June 30, 2013 , based on the criteria established in Internal Control-Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended June 30, 2013 of the Company and our report dated September 6, 2013 expressed an unqualified opinion on those financial statements and financial statement schedule.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Matrix Service Company:

We have audited the accompanying consolidated balance sheets of Matrix Service Company and subsidiaries (the "Company") as of June 30, 2013 and June 30, 2012 , and the related consolidated statements of income, comprehensive income, changes in stockholders' equity, and cash flows for each of the three years in the period ended June 30, 2013 .  Our audits also included the financial statement schedule listed in the Index at Item 15.  These financial statements and financial statement schedule are the responsibility of the Company's management.  Our responsibility is to express an opinion on the financial statements and the financial statement schedule 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, such consolidated financial statements present fairly, in all material respects, the financial position of Matrix Service Company and subsidiaries as of June 30, 2013 and 2012 , and the results of their operations and their cash flows for each of the three years ended June 30, 2013 , in conformity with accounting principles generally accepted in the United States of America.  Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of June 30, 2013 , based on the criteria established in Internal Control-Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated September 6, 2013 expressed an unqualified opinion on the Company's internal control over financial reporting.
