Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Organization and Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and include the accounts of Matrix Service Company and its subsidiaries (“Matrix” or the “Company”), all of which are wholly owned. Intercompany transactions and balances have been eliminated in consolidation. The Company operates in the United States, Canada, South Korea and Australia. The Company’s reportable segments are Electrical Infrastructure, Oil Gas & Chemical, Storage Solutions and Industrial. Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We believe the most significant estimates and judgments are associated with revenue recognition, the recoverability tests that must be periodically performed with respect to our goodwill and other intangible assets, valuation reserves on our accounts receivable and deferred tax assets, and the estimation of loss contingencies, including liabilities associated with litigation and with the self-insured retentions on our insurance programs. Actual results could materially differ from those estimates. Leases Adoption of New Leases Standard In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Under this guidance, lessees are required to recognize virtually all leases on the balance sheet as a right-of-use asset and an associated operating lease liability or finance lease liability. The right-of-use asset represents the lessee's right to use, or control the use of, a specified asset for the specified lease term. The lease liability represents the lessee's obligation to make lease payments arising from the lease, measured on a discounted basis. Based on certain characteristics, leases are classified as operating leases or finance leases. Operating lease liabilities and right-of-use assets are adjusted to result in a single straight-line lease expense over the life of the lease. Finance lease liabilities and right-of-use assets, which contain provisions similar to capital leases under the prior accounting standards, result in the recognition of interest expense on the lease liability and amortization expense on the right-of-use asset over the term of the lease. On July 1, 2019, the Company adopted the standard using the modified retrospective method. The modified retrospective method permits the Company to record right-of-use assets and lease liabilities for existing leases as of the date of adoption rather than at the beginning of the earliest period presented. The Company recorded operating lease right-of-use assets of $24.6 million and operating lease liabilities of $25.8 million as of July 1, 2019. The adoption of the standard did not have a material impact on the Company’s retained earnings, Condensed Consolidated Statements of Income or Condensed Consolidated Statements of Cash Flows. Financial results reported in prior periods are unchanged and reflect the prior lease accounting standards in place at the time. The Company elected the package of practical expedients permitted under the transition guidance for the new standard, which among other things, allowed the Company to carry forward the historical lease classification of its existing leases. All of the Company's existing leases were classified as operating leases prior to adoption and have retained this classification after adoption. In addition, the Company elected not to utilize the hindsight practical expedient to determine the lease term for existing leases at adoption. Lease Accounting Policy The Company enters into lease arrangements for real estate, construction equipment and information technology equipment in the normal course of business. The Company determines if an arrangement is or contains a lease at inception of the arrangement. An arrangement is determined to be a lease if it conveys the right to control the use of identified property and equipment for a period of time in exchange for consideration. Operating lease right-of-use assets are recognized as the present value of future lease payments over the lease term as of the commencement date, plus any lease payments made prior to commencement, and less any lease incentives received. Operating lease liabilities are recognized as the present value of the future lease payments over the lease term as of the commencement date. Operating lease expense is recognized based on the undiscounted future lease payments over the remaining lease term on a straight-line basis. Lease expense related to short-term leases is recognized on a straight-line basis over the lease term. Determinations with respect to lease term (including any renewals and terminations), incremental borrowing rate used to discount lease payments, variable lease expense and future lease payments require the use of judgment based on the facts and circumstances related to each lease. The Company considers various factors, including economic incentives, intent, past history and business need, to determine the likelihood that a renewal option will be exercised. Right-of-use assets are evaluated for impairment in accordance with our policy for impairment of long-lived assets. Revenue Recognition General Information about our Contracts with Customers Our revenue comes from contracts to provide engineering, procurement, fabrication and construction, repair and maintenance and other services. Our engineering, procurement and fabrication and construction services are usually provided in association with capital projects, which commonly are fixed price contracts and are billed based on project milestones. Our repair and maintenance services typically are cost reimbursable or time and material based contracts and are billed monthly or, for projects of short duration, at the conclusion of the project. The elapsed time from award to completion of performance may be in excess of one year for capital projects. Step 1: Contract Identification We do not recognize revenue unless we have identified a contract with a customer. A contract with a customer exists when it has approval and commitment from both parties, the rights and obligations of the parties are identified, payment terms are identified, the contract has commercial substance, and collectibility is probable. We also evaluate whether a contract should be combined with other contracts and accounted for as one single contract. This evaluation requires judgment and could change the timing of the amount of revenue and profit recorded for a given period. Step 2: Identify Performance Obligations Next, we identify each performance obligation in the contract. A performance obligation is a promise to provide a distinct good or service or a series of distinct goods or services to the customer. Revenue is recognized separately for each performance obligation in the contract. Many of our contracts have one clearly identifiable performance obligation. However, many of our contracts provide the customer an integrated service that includes two or more of the following services: engineering, procurement, fabrication, construction, repair and maintenance services. For these contracts, we do not consider the integrated services to be distinct within the context of the contract when the separate scopes of work combine into a single commercial objective or capability for the customer. Accordingly, we generally identify one performance obligation in our contracts. The determination of the number of performance obligations in a contract requires significant judgment and could change the timing of the amount of revenue recorded for a given period. Step 3: Determine Contract Price After determining the performance obligations in the contract, we determine the contract price. The contract price is the amount of consideration we expect to receive from the customer for completing the performance obligation(s). In a fixed price contract, the contract price is a single lump-sum amount. In reimbursable and time and materials based contracts, the contract price is determined by the agreed upon rates or reimbursements for time and materials expended in completing the performance obligation(s) in the contract. A number of our contracts contain various cost and performance incentives and penalties that can either increase or decrease the contract price. These variable consideration amounts are generally earned or incurred based on certain performance metrics, most commonly related to project schedule or cost targets. We estimate variable consideration at the most likely amount of additional consideration to be received (or paid in the case of penalties), provided that meeting the variable condition is probable. We include estimated amounts of variable consideration in the contract price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the contract price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. We reassess the amount of variable consideration each accounting period until the uncertainty associated with the variable consideration is resolved. Changes in the assessed amount of variable consideration are accounted for prospectively as a cumulative adjustment to revenue recognized in the current period. Step 4: Assign Contract Price to Performance Obligations After determining the contract price, we assign such price to the performance obligation(s) in the contract. If a contract has multiple performance obligations, we assign the contract price to each performance obligation based on the stand-alone selling prices of the distinct services that comprise each performance obligation. Step 5: Recognize Revenue as Performance Obligations are Satisfied We record revenue for contracts with our customers as we satisfy the contracts' performance obligations. We recognize revenue on performance obligations associated with fixed price contracts for engineering, procurement, fabrication and construction services over time since these services create or enhance assets the customer controls as they are being created or enhanced. We measure progress of satisfying these performance obligations by using the percentage-of-completion method, which is based on costs incurred to date compared to the total estimated costs at completion, since it best depicts the transfer of control of assets being created or enhanced to the customer. We recognize revenue over time for reimbursable and time and material based repair and maintenance contracts since the customer simultaneously receives and consumes the benefit of those services as we perform work under the contract. As a practical expedient allowed under the revenue accounting standards, we record revenue for these contracts in the amount to which we have a right to invoice for the services performed provided that we have a right to consideration from the customer in an amount that corresponds directly with the value of the performance completed to date. Costs incurred may include direct labor, direct materials, subcontractor costs and indirect costs, such as salaries and benefits, supplies and tools, equipment costs and insurance costs. Indirect costs are charged to projects based upon direct costs and overhead allocation rates per dollar of direct costs incurred or direct labor hours worked. Typically, customer contracts will include standard warranties that provide assurance that products and services will function as expected. The Company does not sell separate warranties. We have numerous contracts that are in various stages of completion which require estimates to determine the forecasted costs at completion. Due to the nature of the work left to be performed on many of our contracts, the estimation of total cost at completion for fixed price contracts is complex, subject to many variables and requires significant judgment. Estimates of total cost at completion are made each period and changes in these estimates are accounted for prospectively as cumulative adjustments to revenue recognized in the current period. 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. Change Orders Contracts are often modified through change orders, which are changes to the agreed upon scope of work. Most of our change orders, which may be priced or unpriced, are for goods or services that are not distinct from the existing contract due to the significant integration of services provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a change order on the contract price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis. For unpriced change orders, we estimate the increase or decrease to the contract price using the variable consideration method described in the Step 3: Determine Contract Price paragraph above. Unpriced change orders are more fully discussed in Note 7 - Commitments and Contingencies. Claims Sometimes we seek claims for amounts in excess of the contract price for delays, errors in specifications and designs, contract terminations, change orders in dispute or other causes of additional costs incurred by us. Recognition of amounts as additional contract price related to claims is appropriate only if there is a legal basis for the claim. The determination of our legal basis for a claim requires significant judgment. We estimate the change to the contract price using the variable consideration method described in the Step 3: Determine Contract Price paragraph above. Claims are more fully discussed in Note 7 - Commitments and Contingencies. Cash and Cash Equivalents The Company includes as cash equivalents all investments with original maturities of three months or less which are readily convertible into cash. We have cash on deposit at June 30, 2020 with banks in the United States, Canada, South Korea and Australia in excess of Federal Deposit Insurance Corporation ("FDIC"), Canada Deposit Insurance Corporation ("CDIC"), Korea Deposit Insurance Corporation ("KDIC") and Financial Claims Scheme ("FCS") protection limits, respectively. The United States Dollar equivalent of Canadian, South Korean and Australian deposits totaled $13.5 million as of June 30, 2020. Accounts Receivable Accounts receivable are carried on a gross basis, less the allowance for uncollectible accounts. The Company’s customers consist primarily of major integrated oil companies, independent refiners and marketers, power companies, petrochemical companies, pipeline companies, mining companies, contractors and engineering firms. The Company is exposed to the risk of individual customer defaults or depressed cycles in our customers’ industries. To mitigate this risk many of our contracts require payment as projects progress or advance payment in some circumstances. In addition, in most cases the Company can place liens against the property, plant or equipment constructed or terminate the contract if a material contract default occurs. Management estimates the allowance for uncollectible accounts based on existing economic conditions, the financial condition of its customers and the amount and age of past due accounts. Accounts are written off against the allowance for uncollectible accounts only after all reasonable collection attempts have been exhausted. Retentions Contract retentions collectible beyond one year are included in Other assets in the Consolidated Balance Sheets. Accounts payable retentions are generally settled within one year. 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. Inventories Inventories consist primarily of steel plate and pipe and aluminum coil and extrusions. Cost is determined primarily using the average cost method and inventories are stated at the lower of cost or net realizable value. Depreciation Depreciation is computed using the straight-line method over the estimated useful lives of the depreciable assets. Depreciable lives are as follows: buildings—40 years, construction equipment—3 to 15 years, transportation equipment—3 to 5 years, and office equipment and software—3 to 10 years. Leasehold improvements are amortized over the shorter of the useful life of the asset or the lease term. Impairment of Long-Lived Assets The Company evaluates long-lived assets for impairment when events or changes in circumstances indicate, in management’s judgment, that the carrying value of such assets used in operations may not be recoverable. The determination of whether an impairment has occurred is based on management’s estimate of undiscounted future cash flows attributable to the assets as compared to the carrying value of the assets. If an impairment has occurred, the amount of the impairment recognized is determined by estimating the fair value of the assets and, to the extent the carrying value exceeds the fair value of the assets, recording a loss provision. For assets identified to be disposed of in the future, the carrying value of the assets are compared to the estimated fair value less the cost of disposal to determine if an impairment has occurred. Until the assets are disposed of, an estimate of the fair value is redetermined when related events or circumstances change. 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, which is a level below our reportable segments. We perform our annual impairment test in the fourth quarter of each fiscal year, or in between annual tests whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable, to determine whether an impairment exists 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 goodwill impairment test involves comparing management’s estimate of the fair value of a reporting unit with its carrying value, including goodwill. If the fair value of a reporting unit exceeds its carrying value, then goodwill is not impaired. If the fair value of a reporting unit is less than its carrying value, then goodwill is impaired to the extent of the difference, but the impairment may not exceed the balance of goodwill assigned to that reporting unit. We utilize a discounted cash flow analysis, referred to as an income approach, and market multiples, referred to as a market approach, to determine the estimated fair value of our reporting units. For the income approach, significant judgments and assumptions including forecasted project awards, discount rate, anticipated revenue growth rate, gross margins, operating expenses, working capital needs and capital expenditures are inherent in the 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. For the market approach, significant judgments and assumptions include the selection of guideline companies, forecasted guideline company EBITDA and our forecasted EBITDA. 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 additional impairment charges in the financial statements. As a test for reasonableness, we also consider the combined carrying values of our reporting units to our market capitalization. Other Intangible Assets Intangible assets that have finite useful lives are amortized by the straight-line method over their useful lives ranging from 6 years to 15 years. A finite intangible asset is considered impaired when its carrying amount is not recoverable and exceeds the asset's fair value. The carrying amount is deemed unrecoverable if it is greater than the sum of undiscounted cash flows expected to result from use and eventual disposition of the asset. An impairment loss is equal to the excess of the carrying amount over the fair value of the asset. If quoted market prices are not available, the fair values of the intangible assets are based on present values of expected future cash flows or royalties avoided using discount rates commensurate with the risks involved. 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 case-by-case evaluations of the underlying claim data and update our evaluations as further information becomes known. Judgments and assumptions 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 future gains and losses that could be material. Stock-Based Compensation The Company has issued stock options and nonvested deferred share awards under its long-term incentive compensation plans. The fair value of these awards is calculated at grant date. The fair value of time-based, nonvested deferred shares is the value of the Company’s common stock at the grant date. The fair value of market-based nonvested deferred shares is based on several factors, including the probability that the market condition specified in the grant will be achieved, which is calculated using a Monte Carlo model. The fair value of stock options is determined based on the Black-Scholes option pricing model. For all stock-based awards, expense is recognized over the requisite service period with forfeitures recorded as they occur. Income Taxes We use the asset and liability approach for financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances based on our judgments and estimates are established when necessary to reduce deferred tax assets to the amount expected to be realized in future operating results. Company management believes that realization of deferred tax assets in excess of the valuation allowance is more likely than not. Our estimates are based on facts and circumstances in existence as well as interpretations of existing tax regulations and laws applied to the facts and circumstances, with the help of professional tax advisors. Therefore, we estimate and provide for amounts of additional income taxes that may be assessed by the various taxing authorities. Foreign Currency The functional currencies of the Company’s operations in Canada, South Korea and Australia are the Canadian Dollar, South Korean Won and U.S. Dollar, respectively. The functional currency of the Company's Australian operations is the U.S. Dollar since its sales are primarily denominated in that currency. For subsidiaries with operations using a foreign functional currency, assets and liabilities are translated at the year-end exchange rates and the income statement accounts are translated at average exchange rates throughout the year. Translation gains and losses are reported in Accumulated Other Comprehensive Income (Loss), net of tax, in the Consolidated Statements of Changes in Stockholders’ Equity and in Other Comprehensive Income (Loss) in the Consolidated Statements of Comprehensive Income. Translation gains and losses are reversed from Accumulated Other Comprehensive Income (Loss) and are recognized in current period income in the event the Company disposes of an entity with accumulated translation gains or losses. Transaction gains and losses are reported as a component of Other income (expense) in the Consolidated Statements of Income. Recently Issued Accounting Standards Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments On June 16, 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, which will change how the Company accounts for its allowance for uncollectible accounts. The amendments in this update require a financial asset (or a group of financial assets) to be presented at the net amount expected to be collected. The income statement will reflect any increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. Previous GAAP delays the recognition of the full amount of credit losses until the loss is probable of occurring. The amendments in this update eliminate the probable initial recognition threshold and, instead, reflect the Company's current estimate of all expected credit losses. In addition, current guidance limits the information the Company may consider in measuring a credit loss to its past events and current conditions. The amendments in this update broaden the information the Company may consider in developing its expected credit loss estimate to include forecasted information. The Company adopted the standard on July 1, 2020 with no material impact to its estimate of the allowance for uncollectible accounts.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue Remaining Performance Obligations The Company had $566.4 million of remaining performance obligations yet to be satisfied as of June 30, 2020. The Company expects to recognize approximately $429.0 million of its remaining performance obligations as revenue within the next twelve months. Contract Balances Contract terms with customers include the timing of billing and payment, which usually differs from the timing of revenue recognition. As a result, we carry contract assets and liabilities in our balance sheet. These contract assets and liabilities are calculated on a contract-by-contract basis and reported on a net basis at the end of each period and are classified as current. We present our contract assets in the balance sheet as Costs and Estimated Earnings in Excess of Billings on Uncompleted Contracts ("CIE"). CIE consists of revenue recognized in excess of billings. We present our contract liabilities in the balance sheet as Billings on Uncompleted Contracts in Excess of Costs and Estimated Earnings ("BIE"). BIE consists of billings in excess of revenue recognized. The following table provides information about CIE and BIE: June 30, June 30, Change (In thousands) Costs and estimated earnings in excess of billings on uncompleted contracts $ 59,548 $ 96,083 $ (36,535) Billings on uncompleted contracts in excess of costs and estimated earnings (63,889) (105,626) 41,737 Net contract liabilities $ (4,341) $ (9,543) $ 5,202 The difference between the beginning and ending balances of the Company's CIE and BIE primarily results from the timing of revenue recognized relative to its billings. The amount of revenue recognized during the twelve months ended June 30, 2020 that was included in the prior period BIE balance was $104.4 million. This revenue consists primarily of work performed during the period on contracts with customers that had advance billings. Progress billings in accounts receivable at June 30, 2020 and June 30, 2019 included retentions to be collected within one year of $37.3 million and $21.9 million, respectively. Contract retentions collectible beyond one year are included in other assets in the Consolidated Balance Sheets and totaled $1.6 million as of June 30, 2020 and $17.7 million as of June 30, 2019. Disaggregated Revenue Revenue disaggregated by reportable segment is presented in Note 13 - Segment Information. The following series of tables presents revenue disaggregated by geographic area where the work was performed and by contract type: Geographic Disaggregation: Twelve months ended June 30, June 30, June 30, (In thousands) United States $ 1,020,083 $ 1,367,844 $ 981,292 Canada 70,133 41,410 104,208 Other international 10,722 7,426 6,053 Total $ 1,100,938 $ 1,416,680 $ 1,091,553 Contract Type Disaggregation: Twelve months ended June 30, June 30, June 30, (In thousands) Fixed-price contracts $ 685,559 $ 748,007 $ 588,039 Time and materials and other cost reimbursable contracts 415,379 668,673 503,514 Total $ 1,100,938 $ 1,416,680 $ 1,091,553 Typically, the Company assumes more risk with fixed-price contracts since increases in cost to perform the work may not be recoverable. However, these types of contracts typically offer higher profits than time and materials and other cost reimbursable contracts when completed at or below the costs originally estimated. The profitability of time and materials and other cost reimbursable contracts is typically lower than fixed-price contracts and is usually less volatile than fixed-price contracts since the profit component is factored into the rates charged for labor, equipment and materials, or is expressed in the contract as a percentage of the reimbursable costs incurred. The mix of revenue by contract type shifted since the third quarter of fiscal 2020 due to the Company's strategic initiative to exit the domestic iron and steel industry, which was comprised primarily of time and materials and other cost reimbursable contracts.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill The changes in the carrying amount of goodwill by segment are as follows: Electrical Oil Gas & Storage Industrial Total (In thousands) Net balance at June 30, 2017 $ 42,152 $ 33,604 $ 16,764 $ 20,981 $ 113,501 Goodwill impairment (17,281) — — — (17,281) Translation adjustment (1) (45) — (4) (9) (58) Net balance at June 30, 2018 24,826 33,604 16,760 20,972 96,162 Disposal of business (2) — (2,775) — — (2,775) Translation adjustment (1) 4 — (24) 1 (19) Net balance at June 30, 2019 24,830 30,829 16,736 20,973 93,368 Goodwill impairment (24,900) — — (7,981) (32,881) Translation adjustment (1) 70 — (169) (19) (118) Net balance at June 30, 2020 $ — $ 30,829 $ 16,567 $ 12,973 $ 60,369 (1) The translation adjustments relate to the periodic translation of Canadian Dollar and South Korean Won denominated goodwill recorded as a part of prior acquisitions in Canada and South Korea, in which the local currency was determined to be the functional currency. (2) In August 2018, the Company disposed of a business that marketed process heating equipment. See Note 3 - Acquisitions and Disposals for more information about the disposal. The business disposed of constituted its own reporting unit and the amount of goodwill written off was all of the goodwill assigned to that reporting unit. None of the goodwill was considered impaired since the Company recorded a gain on the disposal. The Company performed its annual goodwill impairment test as of May 31, 2020, which resulted in no impairment. The fiscal 2020 test indicated that three reporting units with a combined total of $14.2 million of goodwill as of June 30, 2020 were at higher risk of future impairment than others. If the Company's view of project opportunities or gross margins deteriorates, particularly for the higher risk reporting units, then the Company may be required to record a material impairment of goodwill. During the third quarter of fiscal 2020, the Company concluded that goodwill impairment indicators existed based on the uncertainties caused by the COVID-19 pandemic and the significant decline in the price of crude oil. These uncertainties resulted in lowered revenue expectations for the remainder of fiscal 2020 and fiscal 2021 and led to significant volatility in the Company's stock price. Accordingly, the Company performed an interim test as of March 31, 2020, which did not result in any additional impairments. In the second quarter of fiscal 2020, the Company concluded that a goodwill impairment indicator existed in the Electrical Infrastructure segment based on the recent history of depressed gross margins and the second quarter’s downward acceleration of revenue and gross margin. Accordingly, the Company performed an interim impairment test as of December 31, 2019, reflecting updated revenue and gross margin assumptions, and concluded that the reporting unit's $24.9 million of goodwill was fully impaired. Additionally, the Company concluded that a goodwill impairment indicator existed for an Industrial segment reporting unit based on several second quarter events. These events included the deterioration of our relationship with a significant customer in the iron and steel industry in the second quarter. As a result, the customer canceled other previously awarded work and the Company is expecting little to no new business from this customer in the foreseeable future. Accordingly, the Company performed an interim impairment test as of December 31, 2019 and concluded that the reporting unit's $8.0 million of goodwill was fully impaired. In fiscal 2018, the Company recorded a $17.3 million impairment of goodwill included in the Electrical Infrastructure segment. The impairment was triggered by lower financial projections as a result of the Company's decision to shift its strategy away from EPC power generation projects to smaller, individual packages that better fit the Company's strategy and risk profile, and sluggish maintenance and capital spending by some key clients in our Northeast and Mid-Atlantic high voltage markets. The estimated fair value of each reporting unit was derived primarily by utilizing a discounted cash flow analysis. The key assumptions used are described in Note 1 - Summary of Significant Accounting Policies, Goodwill. Other Intangible Assets In the fourth quarter of fiscal 2020, the Company fully impaired a customer relationship intangible asset with a net book value of $1.2 million. The customer relationship primarily related to services which were impacted by the Company's performance improvement plan (see Note 14 - Restructuring Costs). As a result, the customer relationship intangible asset was no longer recoverable. As of June 30, 2020, this intangible asset had a remaining useful life of approximately 2 years, a gross carrying amount of $6.3 million and accumulated amortization of $5.1 million. The impairment is included in the restructuring costs caption in the Consolidated Statements of Income. Also in the fourth quarter of fiscal 2020, the Company fully impaired a customer relationship intangible asset with a net book value of $0.4 million in connection with the closure of an underperforming operating unit. The closure was part the Company's performance improvement plan (see Note 14 - Restructuring Costs). As of June 30, 2020, this intangible asset had a remaining useful life of approximately 4 years, a gross carrying amount of $0.9 million and accumulated amortization of $0.5 million. The impairment is included in the restructuring costs caption in the Consolidated Statements of Income. In the second quarter of fiscal 2020, in connection with the factors disclosed for the Industrial segment goodwill impairment above, the Company fully impaired a customer relationship with a net book value of $5.6 million. As of December 31, 2019, this intangible asset had a remaining useful life of 9 years, a gross carrying amount of $9.4 million and accumulated amortization of $3.8 million. The impairment is included within the goodwill and other intangible asset impairment caption in the Consolidated Statements of Income. In the fourth quarter of fiscal 2018, the Company recorded a $0.7 million impairment to a customer relationship intangible asset associated with an acquisition that was completed in fiscal 2013. The impairment was triggered by lower than anticipated revenue and operating income. The impairment is included in the Oil Gas & Chemical segment and is presented within the goodwill and other intangible asset impairment caption in the Consolidated Statements of Income. Information on the carrying value of other intangible assets is as follows: At June 30, 2020 Useful Life Gross Accumulated Net Carrying (Years) (In thousands) Intellectual property 10 to 15 $ 2,579 $ (1,956) $ 623 Customer based 6 to 15 21,840 (13,626) 8,214 Non-compete Agreements 4 1,453 (1,453) — Total other intangible assets $ 25,872 $ (17,035) $ 8,837 At June 30, 2019 Useful Life Gross Accumulated Net Carrying (Years) (In thousands) Intellectual property 10 to 15 $ 2,579 $ (1,779) $ 800 Customer based 6 to 15 38,572 (19,915) 18,657 Non-compete agreements 4 1,453 (1,438) 15 Total other intangible assets $ 42,604 $ (23,132) $ 19,472 Amortization expense totaled $3.4 million, $3.3 million, and $4.8 million in fiscal 2020, 2019, and 2018, respectively. We estimate that future amortization of other intangible assets will be as follows (in thousands): For year ending: June 30, 2021 $ 2,231 June 30, 2022 1,811 June 30, 2023 1,729 June 30, 2024 1,415 June 30, 2025 1,096 Thereafter 555 Total estimated amortization expense $ 8,837

The Credit Agreement provides for a five-year senior secured revolving credit facility of $300.0 million that expires February 8, 2022. The credit facility may be used for working capital, acquisitions, capital expenditures, issuances of letters of credit and other lawful purposes. The credit facility includes a U.S. Dollar equivalent sublimit of $75.0 million for revolving loans denominated in Australian Dollars, Canadian Dollars, Euros and Pounds Sterling and letters of credit in Australian Dollars, Euros, and Pounds Sterling. The credit facility also includes a $200.0 million sublimit for total letters of credit. Each revolving borrowing under the Credit Agreement will bear interest at a rate per annum equal to: • The ABR or the Adjusted LIBO Rate, in the case of revolving loans denominated in U.S. Dollars; • The Canadian Prime Rate or the CDOR rate, in the case of revolving loans denominated in Canadian Dollars; • The Adjusted LIBO Rate, in the case of revolving loans denominated in Pounds Sterling or Australian Dollars; or • The EURIBO Rate, in the case of revolving loans denominated in Euros, in each case, plus the Applicable Margin, which is based on the Company's Leverage Ratio. The Applicable Margin on ABR loans ranges between 0.625% and 1.625%. The Applicable Margin for Adjusted LIBO, EURIBO and CDOR loans ranges between 1.625% and 2.625% and the Applicable Margin for Canadian Prime Rate loans ranges between 2.125% and 3.125%. The unused credit facility fee is between 0.25% and 0.45% based on the Leverage Ratio. At June 30, 2020, the Company was at the lowest margin tier for all categories of loans and the unused revolving credit facility fee under the Credit Agreement. The Credit Agreement includes the following covenants and borrowing limitations: • Our Leverage Ratio, determined as of the end of each fiscal quarter, may not exceed 3.00 to 1.00.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Coronavirus Aid, Relief, and Economic Security Act On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (CARES) Act (the "CARES Act") was signed into law. The purpose of the CARES Act was to provide $2.2 trillion in funding to fight the COVID-19 pandemic and provide economic relief in the form of tax relief, government loans and grants. The CARES Act contains the following key provisions which affect income taxes: • Eliminates the 80% of taxable income limitations by allowing corporations to fully utilize net operating loss carryforwards to offset taxable income in 2018, 2019, or 2020 and reinstating it for tax years after 2020; • Allows net operating losses generated in 2018, 2019 or 2020 to be carried back five years; • Increases the net interest expense deduction limit to 50% of adjusted taxable income from 30% for the 2019 and 2020 tax years; • Allows taxpayers with alternative minimum tax credits to claim a refund for the entire amount of the credit instead of recovering the credit through refunds over a period of years, as required by the 2017 Tax Cuts and Jobs Act; and • Allows entities to deduct more of their charitable cash contributions made during calendar year 2020 by increasing the taxable income limitation to 25% from 10%. The income tax provisions in the CARES Act have not had a material impact on the Company as of June 30, 2020. The CARES Act also provides certain payroll tax credits and allows companies to defer payroll tax that would otherwise be due from enactment through December 31, 2020. The Company has recognized $0.8 million of payroll tax credits during fiscal 2020 and has deferred $3.8 million of payroll tax as of June 30, 2020. The payroll tax credits are included as a reduction of selling, general and administrative expenses in the Consolidated Statements of Income and the deferred payroll taxes are included within other liabilities in the Consolidated Balance Sheets. The Company must repay half of the deferred payroll tax by December 31, 2021 and the remainder by December 31, 2022. The Company has also received $1.1 million of subsidies in Canada during fiscal 2020 as part the Canada Emergency Wage Subsidy program, which was designed to compensate Canadian employers whose business has been affected by the COVID-19 pandemic. These subsidies are included as a reduction of selling, general and administrative expenses in the Consolidated Statements of Income.

In fiscal 2018, the Company impaired $17.3 million of goodwill, which included $8.3 million of non-deductible goodwill. See Note 4 - Goodwill and Other Intangible Assets for more information about the impairments. (2) In fiscal 2020, the Company placed $3.1 million of valuation allowances on net operating loss carryforwards and foreign tax credits primarily related to Canada. In fiscal 2019, the Company placed $4.5 million of valuation allowances on net operating loss carryforwards and foreign tax credits generated by its branch operations in Canada, which will likely not be utilized prior to their expiration.

We do not provide for outside basis differences under the indefinite reinvestment assertion of ASC 740-30. The Company files tax returns in multiple domestic and foreign taxing jurisdictions. With a few exceptions, the Company is no longer subject to examination by taxing authorities through fiscal 2015. At June 30, 2020, the Company updated its evaluation of its open tax years in all known jurisdictions. As of June 30, 2020, we have a $0.5 million liability for unrecognized tax positions and the payment of related interest and penalties. We treat the related interest and penalties as income tax expense. Due to the uncertainties related to these tax matters, we are unable to make a reasonably reliable estimate as to when cash settlement with a taxing authority will occur.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Insurance Reserves 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 or as required by the subcontract. 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. Unpriced Change Orders and Claims As of June 30, 2020 and June 30, 2019, costs and estimated earnings in excess of billings on uncompleted contracts included revenue for unpriced change orders and claims of $14.5 million and $10.1 million, respectively. The amounts ultimately realized may be significantly different than the recorded amounts resulting in a material adjustment to future earnings. Generally, collection of amounts related to unpriced change orders and claims is expected within twelve months. However, customers may not pay these amounts until final resolution of related claims, and accordingly, collection of these amounts may extend beyond one year. Other During the third quarter of fiscal 2020, the Company commenced litigation in an effort to collect $17.8 million in accounts receivable from an iron and steel customer following the deterioration of the relationship in the second quarter of fiscal 2020. Based on the terms of the contract with this customer, the Company is entitled to collect the full amount owed under the contract. However, the timing of collection is uncertain.

Leases [Abstract]
Operating Leases	Leases The Company enters into lease arrangements for real estate, construction equipment and information technology equipment in the normal course of business. Real estate leases accounted for approximately 87% of all right-of-use assets as of June 30, 2020. Most real estate and information technology equipment leases generally have fixed payments that follow an agreed upon payment schedule and have remaining lease terms ranging from less than a year to 16 years. Construction equipment leases generally have "month-to-month" lease terms that automatically renew as long as the equipment remains in use. The Company recorded $3.2 million of impairments to right-of-use assets related to leased office space that was closed in connection with the Company's restructuring activities, see Note 14 – Restructuring Costs for additional information. The components of lease expense in the Consolidated Statements of Income are as follows: Fiscal Year Ended June 30, 2020 Lease expense Location of Expense in Statements of Income (in thousands) Operating lease expense Cost of revenue and selling, general and administrative expenses $ 12,274 Short-term lease expense (1) Cost of revenue 37,371 Total lease expense $ 49,645 (1) Primarily represents the lease expense of construction equipment that is subject to month-to-month rental agreements with expected rental durations of less than one year.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders’ Equity Preferred Stock The Company has 5.0 million shares of preferred stock authorized, none of which was issued or outstanding at June 30, 2020 or June 30, 2019. Treasury Shares On November 6, 2018, the Board of Directors approved a stock buyback program (the "November 2018 Program"), which replaced the previous program that had been in place since December 2016 and was set to expire in December 2018. Under the November 2018 Program, the Company may repurchase common stock up to a maximum of $30.0 million per calendar year provided that the aggregate number of shares repurchased may not exceed 10%, or approximately 2.7 million, of the Company's shares outstanding as of November 6, 2018. The Company may repurchase its stock from time to time in the open market at prevailing market prices or in privately negotiated transactions and is not obligated to purchase any shares. The November 2018 Program will continue unless and until it is modified or revoked by the Board of Directors. In fiscal 2020, the Company repurchased 1,047,606 shares of its common stock for $17.0 million under the November 2018 Program. There were 1,349,037 shares available for repurchase under the November 2018 Program as of June 30, 2020. 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. The Company withheld 181,081 and 79,111 shares of common stock during fiscal 2020 and 2019, respectively, to satisfy these obligations. These shares were returned to the Company’s pool of treasury shares. The Company has 1,746,689 treasury shares as of June 30, 2020 and intends to utilize these treasury shares in connection with equity awards under the Company’s stock incentive plans and for sales to the Employee Stock Purchase Plan.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Total stock-based compensation expense for the fiscal years ended June 30, 2020, June 30, 2019, and June 30, 2018 was $9.9 million, $11.9 million and $8.6 million, respectively. Measured but unrecognized stock-based compensation expense at June 30, 2020 was $11.9 million, all of which related to nonvested deferred shares which are expected to be recognized as expense over a weighted average period of 1.6 years. The Company recognized excess tax expense of $0.2 million and $0.5 million related to stock-based compensation vesting for the fiscal years ended June 30, 2020 and 2018, respectively. The Company recognized excess tax benefits of $0.3 million for the fiscal year ended June 30, 2019 related to stock-based compensation vesting. Plan Information In October 2018, the Company's stockholders approved the Matrix Service Company 2018 Stock and Incentive Compensation Plan (the "2018 Plan"), which provides stock-based and cash-based incentives for officers, directors and other key employees. Stock options, restricted stock, restricted stock units, stock appreciation rights, performance shares and cash-based awards can be issued under this plan. Upon approval of the 2018 Plan, the 2016 Stock and Incentive Compensation Plan ("2016 Plan") was frozen with the exception of normal vesting and other activity associated with awards previously granted under the 2016 Plan. The 2016 Plan was preceded by the 2012 Stock Incentive Plan ("2012 Plan"), which was frozen upon approval of the 2016 Plan with the exception of normal vesting, forfeiture and other activity associated with awards previously granted under the 2012 Plan. Shares awarded under either the 2016 Plan or the 2012 Plan that are subsequently forfeited or net settled for tax withholding purposes are returned to the treasury share pool and become available for grant under the 2018 Plan. The 2012 Plan was preceded by the 2004 Stock Incentive Plan ("2004 Plan"), which was frozen upon approval of the 2012 Plan with the exception of normal vesting, forfeiture and other activity associated with awards previously granted under the 2004 Plan. Awards totaling 1,600,000 shares have been authorized under the 2018 Plan. There were 1,473,424 shares available for grant under the 2018 Plan as of June 30, 2020. Stock Options Stock options are granted at the market value of the Company’s common stock on the grant date and expire after 10 years. The Company’s policy is to issue shares upon the exercise of stock options from its treasury shares, if available. The Company did not award any new stock options in fiscal years 2020, 2019, or 2018. Stock option activity and related information for the fiscal year ended June 30, 2020 is as follows: Number of Weighted-Average Weighted-Average Aggregate (Years) (In thousands) Outstanding at June 30, 2019 53,700 2.4 $ 10.19 $ 541 Granted — — — Exercised — — — Canceled — — — Outstanding at June 30, 2020 53,700 1.4 $ 10.19 $ — Vested at June 30, 2020 53,700 1.4 $ 10.19 $ — Exercisable at June 30, 2020 53,700 1.4 $ 10.19 $ — The total intrinsic value of stock options exercised was $0.1 million and $0.3 million during fiscal year 2019 and fiscal 2018, respectively. No stock options were exercised in fiscal 2020. Nonvested Deferred Shares The Company has issued nonvested deferred shares under the following types of arrangements: • Time-based awards—Employee awards generally vest in four one one • Market-based awards—These awards are in the form of performance units which vest 3 years after the grant date only if the Company’s common stock achieves certain levels of total shareholder return when compared to the total shareholder return of a peer group of companies as selected by the Compensation Committee of the Board of Directors. The payout can range from zero to 200% of the original award depending on the Company's relative total shareholder return during the performance period. These awards are settled in stock. As of June 30, 2020, there are approximately 232,000, 170,000, and 200,000 performance units that are scheduled to vest in fiscal 2021, fiscal 2022, and fiscal 2023, respectively, assuming target performance. All awards vest upon the death or disability of the participant or upon a change of control of the Company. The grant date fair value of the time-based awards is determined by the market value of the Company's common stock on the grant date. The grant date fair value of stock options is determined based on the Black-Scholes option pricing model. The grant date fair value of the market-based awards is calculated using a Monte Carlo model. For the fiscal 2020 grant, the model estimated the fair value of the award based on approximately 100,000 simulations of the future prices of the Company's common stock compared to the future prices of the common stock of its peer companies based on historical volatilities. The model also took into account the expected dividends over the performance period of those peer companies which pay cash dividends. Nonvested deferred share activity for the fiscal year ended June 30, 2020 is as follows: Shares Weighted Average Grant Nonvested shares at June 30, 2019 1,459,511 $ 19.88 Shares granted 490,322 $ 21.79 Shares vested and released (542,279) $ 19.43 Shares canceled (172,636) $ 19.51 Nonvested shares at June 30, 2020 1,234,918 $ 20.89 There were 602,148 and 715,539 deferred shares granted in fiscal 2019 and 2018 with average grant date fair values of $25.10 and $13.64 per share, respectively. There were 314,711 and 253,241 deferred shares that vested and were released in fiscal 2019 and 2018 with weighted average fair values of $16.23 and $19.60 per share, respectively.

Earnings Per Share [Abstract]
Earnings per Common Share	Earnings per Common Share Basic earnings per share (“EPS”) is calculated based on the weighted average shares outstanding during the period. Diluted earnings per share includes the dilutive effect of employee and director stock options and nonvested deferred shares. Stock options are considered dilutive whenever the exercise price is less than the average market price of the stock during the period and antidilutive whenever the exercise price exceeds the average market price of the common stock during the period. Nonvested deferred shares are considered dilutive (antidilutive) whenever the average market value of the shares during the period exceeds (is less than) the sum of the related average unamortized compensation expense during the period plus the related hypothetical estimated excess tax benefit that will be realized when the shares vest. Stock options and nonvested deferred shares are considered antidilutive in the event we report a net loss. The computation of basic and diluted EPS is as follows: Fiscal Years Ended June 30, June 30, June 30, (In thousands, except per share data) Basic EPS: Net income (loss) $ (33,074) $ 27,982 $ (11,480) Weighted average shares outstanding 26,621 26,891 26,769 Basic earnings (loss) per share $ (1.24) $ 1.04 $ (0.43) Diluted EPS: Weighted average shares outstanding—basic 26,621 26,891 26,769 Dilutive stock options — 28 — Dilutive nonvested deferred shares — 668 — Diluted weighted average shares 26,621 27,587 26,769 Diluted earnings (loss) per share $ (1.24) $ 1.01 $ (0.43) The following securities are considered antidilutive and have been excluded from the calculation of diluted earnings (loss) per share: Fiscal Years Ended June 30, June 30, June 30, (In thousands of shares) Stock options 19 — 31 Nonvested deferred shares 662 160 424 Total antidilutive securities 681 160 455

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans Defined Contribution Plans The Company sponsors defined contribution savings plans for all eligible employees meeting length of service requirements. Under the primary plan, participants may contribute an amount up to 25% of pretax annual compensation subject to certain limitations. The Company matches 100% of the first 3% of employee contributions and 50% of the next 2% of employee contributions. The Company matching contributions vest immediately. The Company’s matching contributions were $6.2 million in each of the fiscal years ended June 30, 2020 and 2019 and $5.8 million for the fiscal year ended June 30, 2018. Multiemployer Pension Plans The Company contributes to various union sponsored multiemployer benefit plans in the U.S. and Canada. Benefits under these plans are generally based on compensation levels and years of service. For the Company, the financial risks of participating in multiemployer plans are different from single-employer plans in the following respects: • Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers. • If a participating employer discontinues contributions to a plan, the unfunded obligations of the plan may be borne by the remaining participating employers. • If a participating employer chooses to stop participating in a plan, a withdrawal liability may be created based on the unfunded vested benefits for all employees in the plan. Under federal legislation regarding multiemployer pension plans, in the event of a withdrawal from a plan or plan termination, companies are required to continue funding their proportionate share of such plan’s unfunded vested benefits. We are a participant in multiple union sponsored multiemployer plans, and, as a plan participant, our potential obligation could be significant. The amount of the potential obligation is not currently ascertainable because the information required to determine such amount is not identifiable or readily available. Our participation in significant plans for the fiscal year ended June 30, 2020 is outlined in the table below. The “EIN/Pension Plan Number” column provides the Employer Identification Number (“EIN”) and the three digit plan number. The zone status is based on the latest information that the Company received from the plan and is certified by the plan’s actuary. Plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are generally less than 80 percent funded, and plans in the green zone are generally at least 80 percent funded. The “FIP/RP Status Pending/Implemented” column indicates plans for which a financial improvement plan (“FIP”) or a rehabilitation plan (“RP”) is either pending or has been implemented. The “Surcharge Imposed” column includes plans in a red zone status that require a payment of a surcharge in excess of regular contributions. The last column lists the expiration date of the collective-bargaining agreement to which the plan is subject.

For Local 55 Iron Workers Pension Plan and Local 654 IBEW Pension Plan, the Company has not received a funding notification that covers the Company's fiscal year 2019 either. Under Federal pension law, if a multiemployer pension plan is determined to be in critical or endangered status, the plan must provide notice of this status to participants, beneficiaries, the bargaining parties, the Pension Benefit Guaranty Corporation, and the Department of Labor. The Company also observed that these plans have not submitted any Critical or Endangered Status Notices to the Department of Labor for calendar years that we have not received notification. The Critical or Endangered Status Notices can be accessed at https://www.dol.gov/agencies/ebsa/about-ebsa/our-activities/public-disclosure/critical-status-notices.

(4) The Company's collective bargaining agreement with Pipe Fitters Local 597 does not have an expiration date. The agreement was last renegotiated in 2019. Employee Stock Purchase Plan The Matrix Service Company 2011 Employee Stock Purchase Plan (“ESPP”) was effective January 1, 2011. The ESPP allows employees to purchase shares through payroll deductions and members of the Board of Directors to purchase shares from amounts withheld from their cash retainers. Share purchases are limited to an aggregate market value of no greater than $60,000 per calendar year per participant and are purchased from the Company at the current market value with no discount to the participant. Contributions are with after tax earnings and are accumulated in non-interest bearing accounts for quarterly purchases of company stock. Upon the purchase of shares, the participants receive all stockholder rights including dividend and voting rights, and are permitted to sell their shares at any time. The Company has made 1,000,000 shares available under the ESPP. The ESPP can be terminated at any time at the discretion of the Board of Directors and will automatically terminate on January 2, 2021. Shares are issued from Treasury Stock under the ESPP. There were 20,733 shares issued in fiscal 2020, 15,812 shares in fiscal 2019, and 21,920 shares in fiscal 2018.

Segment Reporting [Abstract]
Segment Information	Segment Information In fiscal 2020, we operated our business through four reportable segments: Electrical Infrastructure; Oil Gas & Chemical; Storage Solutions; and Industrial. The Electrical Infrastructure segment consists of power delivery services provided to investor owned utilities, including construction of new substations, upgrades of existing substations, short-run transmission line installations, distribution upgrades and maintenance, as well as emergency and storm restoration services. We also provide construction and maintenance services to a variety of power generation facilities, such as combined cycle plants and other natural gas fired power stations. The Oil Gas & Chemical segment serves customers primarily in the downstream and midstream petroleum industries who are engaged in refining crude oil and processing, fractionating, and marketing of natural gas and natural gas liquids. We also perform work in the petrochemical, and sulfur extraction, recovery and processing markets. Our services include plant maintenance, turnarounds, engineering and capital construction. We also offer industrial cleaning services, including hydro-blasting, hydro-excavating, advanced chemical cleaning and vacuum services. The Storage Solutions segment consists of work related to aboveground storage tanks ("AST") and terminals. Also included in this segment are cryogenic and other specialty storage tanks and terminals including liquefied natural gas, liquid nitrogen/liquid oxygen, liquid petroleum and other specialty vessels such as spheres as well as marine structures and truck and rail loading/offloading facilities. Our services include engineering, fabrication and construction, and maintenance and repair, which includes planned and emergency services for both tanks and full terminals. Finally, we offer AST products, including geodesic domes, aluminum internal floating roofs, floating suction and skimmer systems, roof drain systems and floating roof seals. The Process and Industrial Facilities segment includes engineering, maintenance, turnarounds and capital projects for the refining, chemical and petrochemical industries; midstream natural gas processing; other industrial processing facilities including biofuels, fertilizer, and sulfur; mining and minerals infrastructure; and thermal vacuum chambers. This segment is similar to the former Oil Gas & Chemical segment described above, but includes mining and minerals, thermal vacuum chambers, and work in other industrial facilities which were historically reported in the Industrial segment. Due to changing markets facing our clients and to better align the financial reporting of the Company with our long-term strategic growth areas, we are changing our reporting segments. Beginning in fiscal 2021, the Company’s financial results will be reported under the following three segments: Utility and Power Infrastructure; Process and Industrial Facilities; and Storage and Terminal Solutions. The services provided by each of these segments is described below. The Utility and Power Infrastructure segment includes services provided in power delivery and power generation, as well as natural gas utility peak shaving. This segment is similar to the former Electrical Infrastructure segment described above, but includes natural gas utility peak shaving facilities that have been historically reported in the Storage Solutions segment. The Process and Industrial Facilities segment includes engineering, maintenance, turnarounds and capital projects for the refining, chemical and petrochemical industries; midstream natural gas processing; other industrial processing facilities including biofuels, fertilizer, and sulfur; mining and minerals infrastructure; and thermal vacuum chambers. This segment is similar to the former Oil Gas & Chemical segment described above, but includes mining and minerals as well as thermal vacuum chambers, which were historically reported in the Industrial segment. The Storage and Terminal Solutions segment includes engineering, construction, maintenance and repair for aboveground storage tanks and terminals; LNG facilities for import/export fueling and bunkering; NGL and other specialty vessels; aboveground storage tank products; and other renewable energy storage and terminal solutions. This segment is similar to the former Storage Solutions segment described above, but does not include the natural gas utility peak shaving facilities, which will be reported as part of the Utility and Power Infrastructure segment. The Company evaluates performance and allocates resources based on operating income. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. Intersegment sales and transfers are recorded at cost; therefore, no intercompany profit or loss is recognized. Segment assets consist primarily of accounts receivable, costs and estimated earnings in excess of billings on uncompleted contracts, property, plant and equipment, goodwill and other intangible assets.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	Restructuring Costs In February 2020, the Company announced a business improvement plan for the Electrical Infrastructure segment and its strategic initiative to exit the domestic iron and steel industry. Planned activities under the business improvement plan and the wind down of the domestic iron and steel industry were expanded in the second half of the year due to lower revenue in fiscal 2020 and uncertainties caused by the COVID-19 pandemic. The business improvement plan consisted of discretionary cost reductions, workforce reductions and closures of certain offices in order to increase the utilization of the Company's staff and bring the cost structure of the business in line with the near-term revenue expectation. The restructuring costs are primarily comprised of severance and personnel-related costs related to reductions in workforce and impairments of operating lease right-of-use assets, other intangible assets and other fixed assets related to the closure of certain offices. The Company incurred $14.0 million of restructuring costs in fiscal 2020 and has substantially completed its business improvement plan and the wind down of the domestic iron and steel business as of June 30, 2020. Restructuring costs incurred are classified as follows: Fiscal Year Ended (in thousands) Electrical Infrastructure Severance costs and other benefits $ 1,571 Facility costs 234 Other intangible asset impairments 1,150 Total Electrical Infrastructure $ 2,955 Oil Gas & Chemical Severance costs and other benefits $ 1,767 Facility costs 1,708 Other intangible asset impairments 375 Total Oil Gas & Chemical $ 3,850 Storage Solutions Severance costs and other benefits $ 576 Facility costs 720 Other intangible asset impairments — Total Storage Solutions $ 1,296 Industrial Severance costs and other benefits $ 4,861 Facility costs 1,048 Other intangible asset impairments — Total Industrial $ 5,909 Total restructuring costs $ 14,010 Restructuring Costs by Type: Total severance costs and other benefits $ 8,775 Total facility costs 3,710 Total other intangible asset impairments 1,525 Total restructuring costs $ 14,010 The table below is a reconciliation of the beginning and ending restructuring reserve balance (in thousands): Balance as of June 30, 2019 $ — Restructuring costs incurred 14,010 Non-cash restructuring costs (5,215) Cash payments (6,392) Balance as of June 30, 2020 (1) $ 2,403 (1) The restructuring reserve is included within other accrued expenses in the Consolidated Balance Sheets.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jun. 30, 2020
Accounting Policies [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and include the accounts of Matrix Service Company and its subsidiaries (“Matrix” or the “Company”), all of which are wholly owned. Intercompany transactions and balances have been eliminated in consolidation. The Company operates in the United States, Canada, South Korea and Australia. The Company’s reportable segments are Electrical Infrastructure, Oil Gas & Chemical, Storage Solutions and Industrial.
Use of Estimates	Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We believe the most significant estimates and judgments are associated with revenue recognition, the recoverability tests that must be periodically performed with respect to our goodwill and other intangible assets, valuation reserves on our accounts receivable and deferred tax assets, and the estimation of loss contingencies, including liabilities associated with litigation and with the self-insured retentions on our insurance programs. Actual results could materially differ from those estimates.
Leases	Lease Accounting Policy The Company enters into lease arrangements for real estate, construction equipment and information technology equipment in the normal course of business. The Company determines if an arrangement is or contains a lease at inception of the arrangement. An arrangement is determined to be a lease if it conveys the right to control the use of identified property and equipment for a period of time in exchange for consideration. Operating lease right-of-use assets are recognized as the present value of future lease payments over the lease term as of the commencement date, plus any lease payments made prior to commencement, and less any lease incentives received. Operating lease liabilities are recognized as the present value of the future lease payments over the lease term as of the commencement date. Operating lease expense is recognized based on the undiscounted future lease payments over the remaining lease term on a straight-line basis. Lease expense related to short-term leases is recognized on a straight-line basis over the lease term. Determinations with respect to lease term (including any renewals and terminations), incremental borrowing rate used to discount lease payments, variable lease expense and future lease payments require the use of judgment based on the facts and circumstances related to each lease. The Company considers various factors, including economic incentives, intent, past history and business need, to determine the likelihood that a renewal option will be exercised. Right-of-use assets are evaluated for impairment in accordance with our policy for impairment of long-lived assets.
Revenue Recognition	Revenue Recognition General Information about our Contracts with Customers Our revenue comes from contracts to provide engineering, procurement, fabrication and construction, repair and maintenance and other services. Our engineering, procurement and fabrication and construction services are usually provided in association with capital projects, which commonly are fixed price contracts and are billed based on project milestones. Our repair and maintenance services typically are cost reimbursable or time and material based contracts and are billed monthly or, for projects of short duration, at the conclusion of the project. The elapsed time from award to completion of performance may be in excess of one year for capital projects. Step 1: Contract Identification We do not recognize revenue unless we have identified a contract with a customer. A contract with a customer exists when it has approval and commitment from both parties, the rights and obligations of the parties are identified, payment terms are identified, the contract has commercial substance, and collectibility is probable. We also evaluate whether a contract should be combined with other contracts and accounted for as one single contract. This evaluation requires judgment and could change the timing of the amount of revenue and profit recorded for a given period. Step 2: Identify Performance Obligations Next, we identify each performance obligation in the contract. A performance obligation is a promise to provide a distinct good or service or a series of distinct goods or services to the customer. Revenue is recognized separately for each performance obligation in the contract. Many of our contracts have one clearly identifiable performance obligation. However, many of our contracts provide the customer an integrated service that includes two or more of the following services: engineering, procurement, fabrication, construction, repair and maintenance services. For these contracts, we do not consider the integrated services to be distinct within the context of the contract when the separate scopes of work combine into a single commercial objective or capability for the customer. Accordingly, we generally identify one performance obligation in our contracts. The determination of the number of performance obligations in a contract requires significant judgment and could change the timing of the amount of revenue recorded for a given period. Step 3: Determine Contract Price After determining the performance obligations in the contract, we determine the contract price. The contract price is the amount of consideration we expect to receive from the customer for completing the performance obligation(s). In a fixed price contract, the contract price is a single lump-sum amount. In reimbursable and time and materials based contracts, the contract price is determined by the agreed upon rates or reimbursements for time and materials expended in completing the performance obligation(s) in the contract. A number of our contracts contain various cost and performance incentives and penalties that can either increase or decrease the contract price. These variable consideration amounts are generally earned or incurred based on certain performance metrics, most commonly related to project schedule or cost targets. We estimate variable consideration at the most likely amount of additional consideration to be received (or paid in the case of penalties), provided that meeting the variable condition is probable. We include estimated amounts of variable consideration in the contract price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the contract price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. We reassess the amount of variable consideration each accounting period until the uncertainty associated with the variable consideration is resolved. Changes in the assessed amount of variable consideration are accounted for prospectively as a cumulative adjustment to revenue recognized in the current period. Step 4: Assign Contract Price to Performance Obligations After determining the contract price, we assign such price to the performance obligation(s) in the contract. If a contract has multiple performance obligations, we assign the contract price to each performance obligation based on the stand-alone selling prices of the distinct services that comprise each performance obligation. Step 5: Recognize Revenue as Performance Obligations are Satisfied We record revenue for contracts with our customers as we satisfy the contracts' performance obligations. We recognize revenue on performance obligations associated with fixed price contracts for engineering, procurement, fabrication and construction services over time since these services create or enhance assets the customer controls as they are being created or enhanced. We measure progress of satisfying these performance obligations by using the percentage-of-completion method, which is based on costs incurred to date compared to the total estimated costs at completion, since it best depicts the transfer of control of assets being created or enhanced to the customer. We recognize revenue over time for reimbursable and time and material based repair and maintenance contracts since the customer simultaneously receives and consumes the benefit of those services as we perform work under the contract. As a practical expedient allowed under the revenue accounting standards, we record revenue for these contracts in the amount to which we have a right to invoice for the services performed provided that we have a right to consideration from the customer in an amount that corresponds directly with the value of the performance completed to date. Costs incurred may include direct labor, direct materials, subcontractor costs and indirect costs, such as salaries and benefits, supplies and tools, equipment costs and insurance costs. Indirect costs are charged to projects based upon direct costs and overhead allocation rates per dollar of direct costs incurred or direct labor hours worked. Typically, customer contracts will include standard warranties that provide assurance that products and services will function as expected. The Company does not sell separate warranties. We have numerous contracts that are in various stages of completion which require estimates to determine the forecasted costs at completion. Due to the nature of the work left to be performed on many of our contracts, the estimation of total cost at completion for fixed price contracts is complex, subject to many variables and requires significant judgment. Estimates of total cost at completion are made each period and changes in these estimates are accounted for prospectively as cumulative adjustments to revenue recognized in the current period. 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. Change Orders Contracts are often modified through change orders, which are changes to the agreed upon scope of work. Most of our change orders, which may be priced or unpriced, are for goods or services that are not distinct from the existing contract due to the significant integration of services provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a change order on the contract price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis. For unpriced change orders, we estimate the increase or decrease to the contract price using the variable consideration method described in the Step 3: Determine Contract Price paragraph above. Unpriced change orders are more fully discussed in Note 7 - Commitments and Contingencies. Claims Sometimes we seek claims for amounts in excess of the contract price for delays, errors in specifications and designs, contract terminations, change orders in dispute or other causes of additional costs incurred by us. Recognition of amounts as additional contract price related to claims is appropriate only if there is a legal basis for the claim. The determination of our legal basis for a claim requires significant judgment. We estimate the change to the contract price using the variable consideration method described in the Step 3: Determine Contract Price paragraph above. Claims are more fully discussed in Note 7 - Commitments and Contingencies.
Cash Equivalents	Cash and Cash Equivalents The Company includes as cash equivalents all investments with original maturities of three months or less which are readily convertible into cash. We have cash on deposit at June 30, 2020 with banks in the United States, Canada, South Korea and Australia in excess of Federal Deposit Insurance Corporation ("FDIC"), Canada Deposit Insurance Corporation ("CDIC"), Korea Deposit Insurance Corporation ("KDIC") and Financial Claims Scheme ("FCS") protection limits, respectively. The United States Dollar equivalent of Canadian, South Korean and Australian deposits totaled $13.5 million as of June 30, 2020.
Accounts Receivable	Accounts Receivable Accounts receivable are carried on a gross basis, less the allowance for uncollectible accounts. The Company’s customers consist primarily of major integrated oil companies, independent refiners and marketers, power companies, petrochemical companies, pipeline companies, mining companies, contractors and engineering firms. The Company is exposed to the risk of individual customer defaults or depressed cycles in our customers’ industries. To mitigate this risk many of our contracts require payment as projects progress or advance payment in some circumstances. In addition, in most cases the Company can place liens against the property, plant or equipment constructed or terminate the contract if a material contract default occurs. Management estimates the allowance for uncollectible accounts based on existing economic conditions, the financial condition of its customers and the amount and age of past due accounts. Accounts are written off against the allowance for uncollectible accounts only after all reasonable collection attempts have been exhausted.
Retentions	Retentions Contract retentions collectible beyond one year are included in Other assets in the Consolidated Balance Sheets. Accounts payable retentions are generally settled within one year.
Loss Contingencies	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.
Inventories	Inventories Inventories consist primarily of steel plate and pipe and aluminum coil and extrusions. Cost is determined primarily using the average cost method and inventories are stated at the lower of cost or net realizable value.
Depreciation	Depreciation Depreciation is computed using the straight-line method over the estimated useful lives of the depreciable assets. Depreciable lives are as follows: buildings—40 years, construction equipment—3 to 15 years, transportation equipment—3 to 5 years, and office equipment and software—3 to 10 years. Leasehold improvements are amortized over the shorter of the useful life of the asset or the lease term.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company evaluates long-lived assets for impairment when events or changes in circumstances indicate, in management’s judgment, that the carrying value of such assets used in operations may not be recoverable. The determination of whether an impairment has occurred is based on management’s estimate of undiscounted future cash flows attributable to the assets as compared to the carrying value of the assets. If an impairment has occurred, the amount of the impairment recognized is determined by estimating the fair value of the assets and, to the extent the carrying value exceeds the fair value of the assets, recording a loss provision.
Goodwill	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, which is a level below our reportable segments. We perform our annual impairment test in the fourth quarter of each fiscal year, or in between annual tests whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable, to determine whether an impairment exists 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 goodwill impairment test involves comparing management’s estimate of the fair value of a reporting unit with its carrying value, including goodwill. If the fair value of a reporting unit exceeds its carrying value, then goodwill is not impaired. If the fair value of a reporting unit is less than its carrying value, then goodwill is impaired to the extent of the difference, but the impairment may not exceed the balance of goodwill assigned to that reporting unit. We utilize a discounted cash flow analysis, referred to as an income approach, and market multiples, referred to as a market approach, to determine the estimated fair value of our reporting units. For the income approach, significant judgments and assumptions including forecasted project awards, discount rate, anticipated revenue growth rate, gross margins, operating expenses, working capital needs and capital expenditures are inherent in the 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. For the market approach, significant judgments and assumptions include the selection of guideline companies, forecasted guideline company EBITDA and our forecasted EBITDA. 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 additional impairment charges in the financial statements. As a test for reasonableness, we also consider the combined carrying values of our reporting units to our market capitalization.
Other Intangible Assets	Other Intangible Assets Intangible assets that have finite useful lives are amortized by the straight-line method over their useful lives ranging from 6 years to 15 years. A finite intangible asset is considered impaired when its carrying amount is not recoverable and exceeds the asset's fair value. The carrying amount is deemed unrecoverable if it is greater than the sum of undiscounted cash flows expected to result from use and eventual disposition of the asset. An impairment loss is equal to the excess of the carrying amount over the fair value of the asset. If quoted market prices are not available, the fair values of the intangible assets are based on present values of expected future cash flows or royalties avoided using discount rates commensurate with the risks involved.
Insurance Reserves	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 case-by-case evaluations of the underlying claim data and update our evaluations as further information becomes known. Judgments and assumptions 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 future gains and losses that could be material.
Stock-Based Compensation	Stock-Based Compensation The Company has issued stock options and nonvested deferred share awards under its long-term incentive compensation plans. The fair value of these awards is calculated at grant date. The fair value of time-based, nonvested deferred shares is the value of the Company’s common stock at the grant date. The fair value of market-based nonvested deferred shares is based on several factors, including the probability that the market condition specified in the grant will be achieved, which is calculated using a Monte Carlo model. The fair value of stock options is determined based on the Black-Scholes option pricing model. For all stock-based awards, expense is recognized over the requisite service period with forfeitures recorded as they occur.
Income Taxes	Income TaxesWe use the asset and liability approach for financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances based on our judgments and estimates are established when necessary to reduce deferred tax assets to the amount expected to be realized in future operating results. Company management believes that realization of deferred tax assets in excess of the valuation allowance is more likely than not. Our estimates are based on facts and circumstances in existence as well as interpretations of existing tax regulations and laws applied to the facts and circumstances, with the help of professional tax advisors. Therefore, we estimate and provide for amounts of additional income taxes that may be assessed by the various taxing authorities.
Foreign Currency	Foreign Currency The functional currencies of the Company’s operations in Canada, South Korea and Australia are the Canadian Dollar, South Korean Won and U.S. Dollar, respectively. The functional currency of the Company's Australian operations is the U.S. Dollar since its sales are primarily denominated in that currency. For subsidiaries with operations using a foreign functional currency, assets and liabilities are translated at the year-end exchange rates and the income statement accounts are translated at average exchange rates throughout the year. Translation gains and losses are reported in Accumulated Other Comprehensive Income (Loss), net of tax, in the Consolidated Statements of Changes in Stockholders’ Equity and in Other Comprehensive Income (Loss) in the Consolidated Statements of Comprehensive Income. Translation gains and losses are reversed from Accumulated Other Comprehensive Income (Loss) and are recognized in current period income in the event the Company disposes of an entity with accumulated translation gains or losses. Transaction gains and losses are reported as a component of Other income (expense) in the Consolidated Statements of Income.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments On June 16, 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, which will change how the Company accounts for its allowance for uncollectible accounts. The amendments in this update require a financial asset (or a group of financial assets) to be presented at the net amount expected to be collected. The income statement will reflect any increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. Previous GAAP delays the recognition of the full amount of credit losses until the loss is probable of occurring. The amendments in this update eliminate the probable initial recognition threshold and, instead, reflect the Company's current estimate of all expected credit losses. In addition, current guidance limits the information the Company may consider in measuring a credit loss to its past events and current conditions. The amendments in this update broaden the information the Company may consider in developing its expected credit loss estimate to include forecasted information. The Company adopted the standard on July 1, 2020 with no material impact to its estimate of the allowance for uncollectible accounts.
