TULSA, OK – September 5, 2012 – Matrix Service Company (Nasdaq: MTRX) today reported its financial results for the fourth quarter and fiscal year ended June 30, 2012.

Overview

Results for the three and twelve months ended June 30, 2012 continue to show strong revenue growth with significant increases in the Storage Solutions and Oil Gas & Chemical segments. The pace of bookings remains strong in all segments with backlog growing to a record $497.5 million as of June 30, 2012, marking six consecutive quarters of growth. Bid flow remains strong with over $831.4 million of new work booked in fiscal 2012.

John R. Hewitt, President and CEO of Matrix Service Company, said “The solid revenue and backlog growth in the quarter and fiscal year is the result of our outstanding people and commitment to providing quality services to our customers. We continue to execute our strategic plan, including our new brand rollout last month.”

Fourth Quarter of Fiscal 2012 Results

Revenues for the fourth quarter ended June 30, 2012 were $184.9 million compared to $163.6 million in the same period a year earlier, an increase of $21.3 million, or 13.0%. Net income for the fourth quarter of fiscal 2012 was $1.8 million, or $0.07 per fully diluted share. Fourth quarter earnings included an income tax charge of $3.1 million, or $0.12 per fully diluted share. The income tax charge represents adjustments of $2.1 million for prior fiscal years and $1.0 million in fiscal 2012, of which $0.2 million related to fourth quarter activity. Fourth quarter earnings were also reduced by $0.03 per fully diluted share for activity related to our strategic investments, primarily due to our investments in the mining and minerals business, industrial cleaning, corporate development, and the branding initiative. In the same period a year earlier the Company earned $5.7 million or $0.21 per fully diluted share.

Consolidated gross profit was $18.7 million in the fourth quarter of fiscal 2012 compared to $20.9 million in the same period a year earlier. The decrease in gross profit was due to lower gross margins, which decreased from 12.8% in the fourth quarter of fiscal 2011 to 10.1% in the fourth quarter of fiscal 2012 largely offset by the impact of higher revenues. The decrease in margins was primarily due to geographic expansion in the Storage Solutions segment, strategic start-up costs, and a lower volume of work in the Industrial segment. The revenue increase is due to continued growth in the Storage Solutions business in Canada, and higher revenues in the Oil Gas & Chemical and Electrical Infrastructure segments, partially offset by lower Industrial revenue, which decreased due to project timing. Selling, general and administrative expenses were $12.2 million, or 6.6% of revenue, in the fourth quarter of fiscal 2012 compared to $11.4 million, or 6.9% of revenue, in the same period a year earlier.

Fiscal 2012 Results

Fiscal year 2012 revenues were $739.0 million compared to $627.1 million in fiscal 2011, an increase of $111.9 million, or 17.8%. Net income for fiscal 2012 was $17.2 million, or $0.65 per fully diluted share. Fiscal 2012 earnings included an income tax charge of $3.1 million, or $0.12 per fully diluted share. Fiscal 2012 earnings were also reduced by $0.07 per fully diluted share for activity related to our strategic investments, primarily due to our investments in the mining and minerals business, industrial cleaning, corporate development and the branding initiative. Net income for fiscal 2011 was $19.0 million, or $0.71 per fully diluted share.

Consolidated gross profit was $79.6 million in fiscal 2012 compared to $74.9 million in the same period a year earlier. The increase in gross profit was due to the impact of higher revenues partially offset by the effect of lower gross margins, which decreased from 11.9% in fiscal 2011 to 10.8% in fiscal 2012. The revenue increase is due to higher revenues in Oil Gas & Chemical resulting from turnaround and capital construction work and higher Storage Solutions revenues, which increased due to more work across most of the business. These increases were partially offset by lower Electrical Infrastructure and Industrial revenues. Selling, general and administrative expenses were $48.0 million, or 6.5% of revenues, in fiscal 2012 compared to $44.0 million, or 7.0% of revenue, in the same period a year earlier.

Backlog

Backlog at June 30, 2012 totaled $497.5 million, an increase of $42.5 million, or 9.3%, compared to the backlog at March 31, 2012, and an increase of $92.3 million, or 22.8%, compared to backlog at June 30, 2011.

Financial Position

At June 30, 2012, Matrix Service’s cash balance was $39.7 million. The cash balance along with the availability under the senior credit facility gives the Company liquidity of $146.5 million.

Earnings Guidance

The Company expects that fiscal 2013 revenues will be between $800 million and $850 million and earnings to be between $0.83 and $0.98 per fully diluted share.

Backlog

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

• fixed-price awards;

• minimum customer commitments on cost plus arrangements; and

• certain time and material arrangements in which the estimated 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 revenues recognized as of the reporting date.
