TULSA, OK – January 8, 2009 – Matrix Service Co. (Nasdaq: MTRX), a leading industrial services company, today reported its financial results for the second quarter ended November 30, 2008.

Second Quarter of Fiscal 2009 Results

Total revenues for the second quarter were $176.9 million compared to the $194.7 million recorded in the second quarter of fiscal 2008. Net income for the second quarter of fiscal 2009 was $10.1 million, or $0.38 per fully diluted share, a $9.9 million increase over prior year second quarter net income of $0.2 million, or $0.01 per fully diluted share. The prior year second quarter results included a pre-tax charge of $16.0 million for cost overruns on a liquefied natural gas (LNG) construction project in the Gulf Coast Region.

Michael J. Bradley, chief executive officer stated, “I am pleased to report that Matrix Service continued its solid operating performance in the second quarter of fiscal 2009. This performance on a sequential basis demonstrates the successful execution of our project backlog and our long-term business strategy. In connection with our long-term business strategy, we recently completed the acquisition of engineering and construction assets and technology from CB&I. We welcome the new employees from this acquisition to Matrix Service and expect this transaction to strengthen our service offerings in key markets.”

Construction Services revenues were $100.1 million, down 13.9% from $116.2 million in the same period a year earlier. The $16.1 million decrease was a result of lower Aboveground Storage Tank (AST) revenues, which decreased 22.8% to $45.0 million in fiscal 2009 from $58.3 million a year earlier and lower Specialty revenues, which decreased $8.9 million to $4.3 million in fiscal 2009 from $13.2 million a year earlier, partially offset by higher revenues in Downstream Petroleum, which increased 6.6% to $42.1 million in fiscal 2009 from $39.5 million a year earlier and higher Electrical and Instrumentation (E&I) revenues, which improved $3.5 million. Construction Services’ gross margins improved to 12.7% from (1.6)% due primarily to the $16.0 million charge taken on the LNG project in the second quarter of fiscal 2008.

Revenues for the Repair and Maintenance Services segment were $76.8 million compared to $78.5 million a year earlier. The change was due to lower Downstream Petroleum revenues, which decreased $8.6 million to $21.2 million in fiscal 2009 from $29.8 million a year earlier. Largely offsetting this decline was higher AST revenues, which increased 15.3% to $51.3 million in fiscal 2009 from $44.5 million in the prior fiscal year. Gross margins in the second quarter of fiscal 2009 for this segment were 17.7% as compared to 16.7% earned in the second quarter of fiscal 2008.

Consolidated SG&A expenses were $11.8 million in both the second quarter of fiscal 2009 and the second quarter of fiscal 2008. SG&A expense as a percentage of revenue increased to 6.7% in the second quarter of fiscal 2009 compared to 6.1% in the second quarter of fiscal 2008 due to the 9.1% decline in revenues.

EBITDA⁽¹⁾ increased to $17.2 million, from $1.5 million in the same period last year. Gross margins on a consolidated basis for the current quarter increased to 14.9% from 5.8% in the same quarter a year ago as gross margins in both segments improved.

Consolidated backlog at November 30, 2008 was $454.0 million as compared to $458.8 million at the end of the first fiscal quarter. The November 30, 2008 backlog does not include the $38 million contract award that was announced separately today as the award occurred in the third quarter.

Six Month Fiscal 2009 Results

Net income for the six month period was $19.6 million, or $0.74 per fully diluted share, compared to $6.5 million, or $0.24 per fully diluted share, in the comparable period last year. The prior year results for the six month period ended November 30, 2007 included pre-tax charges of $17.5 million for cost overruns on an LNG construction project in the Gulf Coast Region.

For the six months ended November 30, 2008, consolidated revenues increased 2.1% to $363.6 million from $356.1 million in the year-earlier period.

Construction Services revenues were $214.9 million for the six month period ended November 30, 2008 compared with $215.1 million in the year earlier period. Included in the $0.2 million decline were lower Specialty revenues, which decreased $23.7 million as the construction of the tanks on a Gulf Coast LNG project was completed in the fourth quarter of fiscal 2008. Largely offsetting this decline were higher revenues in Downstream Petroleum, which increased $13.5 million to $86.5 million in fiscal 2009 from $73.0 million a year earlier, higher E&I revenues, which improved $6.9 million to $14.3 million in fiscal 2009 from $7.4 million a year earlier, and higher AST revenues, which increased $3.1 million to $100.9 million in fiscal 2009 from $97.8 million a year earlier. Construction Services’ gross margins improved to 12.9% from 3.2% due primarily to $17.5 million in pre-tax charges on the LNG project in the six month period ended November 30, 2007.

Revenues for the Repair and Maintenance Services segment increased $7.7 million, or 5.5%, to $148.7 million, for the six month period ended November 30, 2008 from $141.0 million for the same period of fiscal 2008. The improvement was due to higher AST revenues, which increased 15.3% to $99.2 million in fiscal 2009 from $86.0 million in the prior fiscal year. This increase was partially offset by lower Downstream Petroleum revenues, which decreased 10.4% to $42.4 million in fiscal 2009 from $47.3 million a year earlier and lower E&I revenues, which decreased $0.6 million to $7.0 million in fiscal 2009 from $7.6 million a year earlier. Gross margins in fiscal 2009 for the segment were 17.0% as compared to 16.5% earned in the year earlier period.

Consolidated SG&A expenses increased $3.9 million in fiscal 2009 to $23.8 million from $19.9 million for fiscal 2008. The increase was primarily due to costs relating to our expansion into Western Canada and the Gulf Coast Region and higher employee related and facility costs incurred to build the infrastructure and sales force necessary to support our long-term growth plan. SG&A expense as a percentage of revenue increased to 6.6% in fiscal 2009 compared to 5.6% in fiscal 2008.

EBITDA⁽¹⁾ increased to $35.0 million, from $14.1 million in the same period last year. Gross margins on a consolidated basis increased to 14.6% from 8.5% reported a year earlier ago as gross margins in both segments improved.

(1) The Company believes that EBITDA (earnings before net interest, income taxes, depreciation and amortization) is used by the financial community as a method of measuring the Company’s performance and of evaluating the market value of companies considered to be in similar businesses. EBITDA should not be considered as an alternative to net income or cash provided by operating activities, as defined by accounting principles generally accepted in the United States (“GAAP”). A reconciliation of EBITDA to net income is included at the end of this release.

Mr. Bradley added, “In these challenging economic times, we are focused now, more than ever, on continuing with our long-term strategies to grow and diversify our business while producing quality earnings. We have invested in our infrastructure to ensure we are positioned to execute on this strategy and develop additional business opportunities. As a result, we have been able to maintain backlog and continue to see opportunity for long-term future growth. Our bid flow remains very strong and we are currently tracking more than $2 billion of projects.”

Mr. Bradley continued, “As evident in the economy, we experienced a slow down toward the end of the year with anticipated capital awards and maintenance pushed into calendar 2009. Furthermore, there has been a lack of guidance from some of our customers on their capital and maintenance plans as they assess the impact of the economic turmoil on their businesses. Despite these issues and the limited visibility, we expect to achieve earnings around the lower end of our previously stated EPS guidance. Given the expected slowdown in capital spending and lower material costs, we are forecasting fiscal 2009 revenues 10% to 15% below our previous guidance. Our SG&A costs incurred during the first six months of fiscal 2009 included some costs which will not recur. While we remain committed to growing and diversifying our business, we have taken steps to reduce other costs and expect SG&A in the range of 6.0% to 6.5% of revenues. While we are also decreasing our expected capital spending for fiscal 2009 from $25 million to $13 million, the reduction will not impact our business strategy going forward. We are actively managing our liquidity to maintain our strong financial position and to be opportunistic in this economic environment.”

Backlog

We define backlog as the total dollar amount of revenues that we expect to recognize as a result of performing work that has been awarded to us through a signed contract that we consider firm. The following contract types are considered firm:

• fixed-price arrangements;

• minimum customer commitments on cost plus arrangements; and

• certain time and material contracts in which the estimated contract value is firm or can be estimated with a reasonable amount of certainty in both timing and amounts.

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

The following provides a rollforward of our backlog for the three-months ended November 30, 2008:

Non-GAAP Financial Measure

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

• It does not include interest income or expense. Because we borrow money from time to time to finance our operations, interest expense is a necessary and ongoing part of our costs and has assisted us in generating revenue. Therefore, any measure that excludes interest expense has material limitations.

• It does not include income taxes. Because the payment of income taxes is a necessary and ongoing part of our operations, any measure that excludes income taxes has material limitations.

• It does not include depreciation expense. Because we use capital assets to generate revenue, depreciation expense is a necessary element of our cost structure. Therefore, any measure that excludes depreciation expense has material limitations.

A reconciliation of EBITDA to net income follows:
