Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation and Significant Accounting Policies Basis of Presentation The condensed consolidated financial statements include the accounts of Matrix Service Company and its subsidiaries (“Matrix”, “we”, “our”, “us”, “its” or the “Company”), unless otherwise indicated. Intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission and do not include all information and footnotes required by U.S. generally accepted accounting principles ("GAAP") for complete financial statements. The information furnished reflects all adjustments, consisting of normal recurring adjustments, that are, in the opinion of management, necessary for a fair statement of the results of operations, cash flows and financial position for the interim periods presented. The accompanying condensed financial statements should be read in conjunction with the audited financial statements for the year ended June 30, 2020, included in the Company’s Annual Report on Form 10-K for the year then ended. The results of operations for the three month period ended September 30, 2020 may not necessarily be indicative of the results of operations for the full year ending June 30, 2021. Significant Accounting Policies The Company has updated its significant accounting policies to include its accounting policy for recognizing credit losses as a result of adopting the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments-Credit Losses (Topic 326) on July 1, 2020, and our change in reportable segments effective July 1, 2020. The Company's other significant accounting policies are detailed in “Note 1 - Summary of Significant Accounting Policies” of our Annual Report on Form 10-K for the year ended June 30, 2020. Credit Losses Adoption of New Credit Losses Standard On June 16, 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which changed how the Company accounts for credit losses, including those related to its accounts receivable and contract assets. Under this guidance, a financial asset (or a group of financial assets) are required to be presented at the net amount expected to be collected. The income statement reflects any increases or decreases of expected credit losses that have taken place during the period. The amendments in this update eliminate the probable initial recognition threshold and, instead, reflect the Company's current estimate of all lifetime expected credit losses on its accounts receivable and contract asset balances. 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 amounts. The Company determines its allowance for credit losses by using a loss-rate methodology, in which it assesses historical write-offs against total receivables and contract asset balances over several periods. In addition, the Company places reserves on specific balances as needed based on the most recent estimates of collectibility. The Company's adoption of this standard on July 1, 2020 did not have a material impact on its estimate of the allowance for credit losses. Change in Reportable Segments 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 began reporting our financial results under new reportable segments effective July 1, 2020. The new reportable segments along with a description of each are as follows: •Utility and Power Infrastructure: consists of power delivery services provided to investor owned utilities, including construction of new substations, upgrades of existing substations, transmission and distribution line installations, upgrades and maintenance, as well as emergency and storm restoration services. The Company also provides construction and maintenance services to a variety of power generation facilities, including gas fired facilities in simple or combined cycle design, and provides engineering, fabrication, and construction services for liquefied natural gas ("LNG") utility peak shaving facilities. •Process and Industrial Facilities: primarily serves customers 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. The Company also serves customers in various other industries such as petrochemical, sulfur, mining and minerals companies engaged primarily in the extraction of non-ferrous metals, aerospace and defense, cement, agriculture, and other industrial customers. The Company's services include plant maintenance, turnarounds, industrial cleaning services, engineering, fabrication, and capital construction. •Storage and Terminal Solutions: consists of work related to aboveground storage tanks and terminals. Also included in this segment are cryogenic and other specialty storage tanks and terminals, including LNG, 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. The Company's services include engineering, fabrication, construction, and maintenance and repair, which includes planned and emergency services for both tanks and full terminals. Finally, the Company offers tank products, including geodesic domes, aluminum internal floating roofs, floating suction and skimmer systems, roof drain systems and floating roof seals. All prior period segment information has been restated to conform with our new reportable segments. In addition, beginning July 1, 2020, the Company is reporting separately corporate selling, general and administrative expenses and other corporate expenses that were previously allocated to the segments. Refer to Note 9 - Segment Information, and Part I, Item 2 - Management's Discussion and Analysis - Results of Operations, for more information.

Revenue (Notes)

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

Revenue

Remaining Performance Obligations

The Company had $490.4 million of remaining performance obligations yet to be satisfied as of September 30, 2020. The Company expects to recognize $386.0 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:


	September 30, 2020		June 30, 2020		Change
	(in thousands)
Costs and estimated earnings in excess of billings on uncompleted contracts	$	57,694	$	59,548	$	(1,854)
Billings on uncompleted contracts in excess of costs and estimated earnings	(63,523)		(63,889)		366
Net contract liabilities	$	(5,829)	$	(4,341)	$	(1,488)

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 three months ended September 30, 2020 that was included in the June 30, 2020 BIE balance was $41.2 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 September 30, 2020 and June 30, 2020 included retentions to be collected within one year of $33.0 million and $37.3 million, respectively. Contract retentions collectible beyond one year are included in other assets in the Condensed Consolidated Balance Sheet and totaled $3.8 million as of September 30, 2020 and $1.6 million as of June 30, 2020.

Disaggregated Revenue

Revenue disaggregated by reportable segment is presented in Note 9 - Segment Information. The following series of tables presents revenue disaggregated by geographic area where the work was performed and by contract type:

Geographic Disaggregation:


	Three Months Ended
	September 30, 2020		September 30, 2019
	(In thousands)
United States	$	161,377	$	314,416
Canada	19,611		21,170
Other international	1,783		2,511
Total Revenue	$	182,771	$	338,097

Contract Type Disaggregation:


	Three Months Ended
	September 30, 2020		September 30, 2019
	(In thousands)
Fixed-price contracts	$	133,356	$	176,320
Time and materials and other cost reimbursable contracts	49,415		161,777
Total Revenue	$	182,771	$	338,097

Typically, the Company assumes more risk with fixed-price contracts since increases in costs 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.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Leases [Abstract]

Lessee, Operating Leases [Text Block]

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 90% of all right-of-use assets as of September 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 15 years. Construction equipment leases generally have "month-to-month" lease terms that automatically renew as long as the equipment remains in use.

During the three months ended September 30, 2020, the Company recognized a $0.2 million impairment of a right-of-use asset in connection with the closure of a leased office space. The impairment is included in restructuring costs in the condensed consolidated statements of income.

The components of lease expense in the condensed consolidated statements of income are as follows:


		Three Months Ended

Short-term lease expense(1)	Cost of revenue	5,975		9,608
Total lease expense		$	8,463	$	12,725

(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.

The future undiscounted lease payments, as reconciled to the discounted operating lease liabilities presented in the Company's Condensed Consolidated Balance Sheets, were as follows:

Net balance at September 30, 2020	$	6,926	$	26,853	$	26,658	$	60,437

(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.

The Company tests its goodwill for impairment annually in May. While there continues to be uncertainty around the near-term level of spending by some of our customers due to the impacts of the COVID-19 pandemic on our markets and the economy, this uncertainty did not result in any impairment indicators as of September 30, 2020. We will continue to monitor the latest developments and perform interim tests for goodwill impairment as needed.

Debt (Notes)

Debt Disclosure [Abstract]

Debt

On November 2, 2020, the Company entered into the Fifth Amended and Restated Credit Agreement (the "Credit Agreement"), by and among the Company and certain foreign subsidiaries, as Borrowers, various subsidiaries of the Company, as Guarantors, JPMorgan Chase Bank, N.A., as Administrative Agent, Sole Lead Arranger and Sole Bookrunner, and the other Lenders party thereto, which replaced the Fourth Amended and Restated Credit Agreement (the "Prior Credit Agreement") that was in place at September 30, 2020, and which is described in Part II, Item 8. Financial Statements and Supplementary Data, Note 5 - Debt, in the Company's Annual Report on Form 10-K for the year ended June 30, 2020.

The Credit Agreement provides for a three-year senior secured revolving credit facility of $200.0 million that expires November 2, 2023. 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 or the Adjusted EURIBOR Rate, in the case of revolving loans denominated in Pounds Sterling or Australian Dollars; or

•The Adjusted EURIBOR 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 1.00% and 2.00%. The Applicable Margin for Adjusted LIBO, Adjusted EURIBOR and CDOR loans ranges between 2.00% and 3.00% and the Applicable Margin for Canadian Prime Rate loans ranges between 2.50% and 3.50%.

The unused credit facility fee is between 0.35% and 0.50% based on the Leverage Ratio.

Covenants and limitations under the Credit Agreement are effective for the quarter ended September 30, 2020 and include the following:

•Our Leverage Ratio, determined as of the end of each fiscal quarter, may not exceed 3.00 to 1.00. The Leverage Ratio covenant requires that Consolidated Funded Indebtedness, as defined in the Credit Agreement, as of the end of any fiscal quarter, may not exceed 3.0 times Consolidated EBITDA, as defined in the Credit Agreement, or "Covenant EBITDA," over the previous four quarters.

•We are required to maintain a Fixed Charge Coverage Ratio ("FCCR"), determined as of the end of each fiscal quarter, greater than or equal to 1.25 to 1.00. The FCCR is calculated as follows:

◦If no borrowings are outstanding at quarter end, then the FCCR covenant requires that, as of the end of any fiscal quarter, Covenant EBITDA, after deducting capital expenditures and dividends for the previous four quarters, may not be less than 1.25 times the total of interest expense and cash paid for income taxes over the previous four quarters plus scheduled maturities of certain indebtedness for the next four quarters.

◦If borrowings are outstanding at quarter end:

▪for the fiscal quarters ending September 30, 2020 through June 30, 2021, Covenant EBITDA, after deducting capital expenditures, dividends, and share repurchases in excess of $7.5 million for the previous four quarters, may not be less than 1.25 times the total of interest expense and cash paid for income taxes over the previous four quarters plus scheduled maturities of certain indebtedness for the next four quarters.

▪for all fiscal quarters ending on or after September 30, 2021, the FCCR is calculated the same except that all share repurchases for the previous four quarters are deducted from Covenant EBITDA.

•Asset dispositions (other than dispositions in which all of the net cash proceeds therefrom are reinvested into the Company and dispositions of inventory and obsolete or unneeded equipment in the ordinary course of business) are limited to $20.0 million per 12-month period.

•Share repurchases are limited to $30.0 million per calendar year.

As of September 30, 2020, the Company is in compliance with all affirmative, negative, and financial covenants under the Credit Agreement.

Availability at September 30, 2020 under the senior secured revolving credit facility established under the Prior Credit Agreement was as follows:


	September 30, 2020		June 30, 2020
	(In thousands)
Senior secured revolving credit facility	$	300,000	$	300,000

Borrowings outstanding	9,383		9,208
Availability under the senior secured revolving credit facility	$	51,716	$	93,399

Availability under the new $200.0 million senior secured revolving credit facility at September 30, 2020 would have been the same if the Credit Agreement had been in place on such date due to the capacity constraint.

Income Tax Disclosure [Abstract]
Income Tax Disclosure	Income Taxes Effective Tax Rate Our effective tax rates for the three months ended September 30, 2020 and September 30, 2019 were (9.8)% and 30.6%, respectively. We expect our effective tax rate to be approximately 27.0% in fiscal 2021. The effective tax rate for the three months ended September 30, 2020 was negatively impacted by a $1.0 million deferred tax asset adjustment. Deferred Payroll Taxes The Company has deferred $7.4 million of U.S. payroll tax as of September 30, 2020 through provisions of the Coronavirus Aid, Relief, and Economic Security (CARES) Act (the "CARES Act"). 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.

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 Costs and estimated earnings in excess of billings on uncompleted contracts included revenues for unpriced change orders and claims of $13.9 million at September 30, 2020 and $14.5 million at June 30, 2020. Generally, collection of amounts related to unpriced change orders and claims is expected within twelve months. However, since customers may not pay these amounts until final resolution of related claims, 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. Litigation is unpredictable, however, based on the terms of the contract with this customer, the Company is entitled to collect the full amount owed under the contract. The Company and its subsidiaries are participants in various legal actions. It is the opinion of management that none of the other known legal actions, including a contract dispute with a customer involving the construction of a crude terminal, will have a material impact on the Company’s financial position, results of operations or liquidity.

Earnings Per Share [Abstract]

Earnings per Common Share

Basic earnings per share (“Basic EPS”) is calculated based on the weighted average shares outstanding during the period. Diluted earnings per share (“Diluted EPS”) includes the dilutive effect of stock options and nonvested deferred shares. In the event we report a loss, stock options and nonvested deferred shares are not included since they are anti-dilutive.

The computation of basic and diluted earnings per share is as follows:

Segment Reporting [Abstract]

Segment Information

Change in Reportable Segments

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 began reporting our financial results under new reportable segments effective July 1, 2020. The new reportable segments along with a description of each are as follows:

•Utility and Power Infrastructure: consists of power delivery services provided to investor owned utilities, including construction of new substations, upgrades of existing substations, transmission and distribution line installations, upgrades and maintenance, as well as emergency and storm restoration services. The Company also provides construction and maintenance services to a variety of power generation facilities, including gas fired facilities in simple or combined cycle design, and provides engineering, fabrication, and construction services for LNG utility peak shaving facilities.

•Process and Industrial Facilities: primarily serves customers 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. The Company also serves customers in various other industries such as petrochemical, sulfur, mining and minerals companies engaged primarily in the extraction of non-ferrous metals, aerospace and defense, cement, agriculture, and other industrial customers. The Company's services include plant maintenance, turnarounds, industrial cleaning services, engineering, fabrication, and capital construction.

•Storage and Terminal Solutions: consists of work related to aboveground storage tanks and terminals. Also included in this segment are cryogenic and other specialty storage tanks and terminals, including LNG, 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. The Company's services include engineering, fabrication, construction, and maintenance and repair, which includes planned and emergency services for both tanks and full terminals. Finally, the Company offers tank products, including geodesic domes, aluminum internal floating roofs, floating suction and skimmer systems, roof drain systems and floating roof seals.

All prior period segment information has been restated to conform with our new reportable segments. In addition, beginning July 1, 2020, the Company is reporting separately corporate selling, general and administrative expenses and other corporate expenses that were previously allocated to the segments.

The Company evaluates performance and allocates resources based on operating income. 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, right-of-use lease assets, goodwill and other intangible assets.

Restructuring Costs (Notes)	Sep. 30, 2020
Restructuring and Related Activities [Abstract]
Restructuring Costs	Restructuring Costs During the second half of fiscal 2020, the Company implemented a business improvement plan related to: •its strategic initiative to exit the domestic iron and steel industry; •the implementation of business improvements in the power delivery portion of the Utility and Power Infrastructure segment; and •the reduction of its cost structure following the decline in revenue caused by the COVID-19 pandemic and related market disruption and the decline in the price of crude oil. 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 expected near-term decrease in revenue. The Company incurred $14.0 million of restructuring costs during fiscal 2020 and substantially completed its restructuring activities under the business improvement plan. However, the Company recognized a $0.3 million gain on restructuring activities during the three months ended September 30, 2020 as a result of various trailing restructuring expenses and credits. The restructuring reserve was $0.9 million as of September 30, 2020, which primarily relates to the unpaid portion of severance costs.

Disclosure Text Block [Abstract]
New Accounting Pronouncements, Policy	Credit Losses Adoption of New Credit Losses Standard On June 16, 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which changed how the Company accounts for credit losses, including those related to its accounts receivable and contract assets. Under this guidance, a financial asset (or a group of financial assets) are required to be presented at the net amount expected to be collected. The income statement reflects any increases or decreases of expected credit losses that have taken place during the period. The amendments in this update eliminate the probable initial recognition threshold and, instead, reflect the Company's current estimate of all lifetime expected credit losses on its accounts receivable and contract asset balances. 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 amounts. The Company determines its allowance for credit losses by using a loss-rate methodology, in which it assesses historical write-offs against total receivables and contract asset balances over several periods. In addition, the Company places reserves on specific balances as needed based on the most recent estimates of collectibility. The Company's adoption of this standard on July 1, 2020 did not have a material impact on its estimate of the allowance for credit losses.
