[MATRIX SERVICE LOGO] QUARTERLY REPORT FOR PERIOD ENDING AUGUST 31, 2002 10701 E. Ute Street . Tulsa, Oklahoma 74116-1517 (918) 838-8822 . Fax (918) 838-8810 NASDAQ MARKET SYSTEM -- SYMBOL: MTRX

First Quarter FY 2003 Letter to Stockholders Net income for the quarter ended August 31, 2002 was $1.6 million or $0.19 per fully diluted share on consolidated revenues of $53.7 million, compared to net income of $1.2 million or $0.15 per fully diluted share on consolidated revenues of $47.7 million for the same period of the prior year. We were very pleased with our performance in the first quarter of $0.19 per fully diluted share, even though Plant Service volumes were lower than the prior year. We believe that the consolidated performance in the second quarter should be similar to the first quarter results, as the Plant Services segment will continue to be slow as no significant turnaround activity is anticipated. Our estimate of earnings for the full year remains unchanged at this time at $0.88 to $0.93 per fully diluted share and we anticipate fully diluted earnings per share for the second quarter of fiscal 2003 to be in the $0.17 to $0.21 range versus $0.20 per fully diluted share for the second quarter last year. The overall demand environment remains very positive with strong bidding activity. We are committed to continuous improvement and appreciate the continued support of our shareholders. /s/ Bradley S.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) NOTE A - BASIS OF PRESENTATION The consolidated financial statements include the accounts of Matrix Service Company ("Matrix") and its subsidiaries, all of which are wholly owned. All significant inter-company balances and transactions have been eliminated in consolidation. The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-0l 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 generally accepted accounting principles for complete financial statements. However, the information furnished reflects all adjustments, consisting only of normal recurring adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods. The accompanying financial statements should be read in conjunction with the audited financial statements for the year ended May 3l, 2002, included in Matrix's Annual Report on Form 10-K for the year then ended. Matrix's business is seasonal; therefore, results for any interim period may not necessarily be indicative of future operating results. -6-

Other comprehensive loss and accumulated other comprehensive loss consisted of foreign currency translation adjustments and fair value adjustments of derivative instruments. NOTE D - INCOME TAXES Deferred income taxes are computed using the liability method whereby deferred tax assets and liabilities are recognized based on temporary differences between financial statement and tax basis of assets and liabilities using presently enacted tax rates. -7-

NOTE E - NEW ACCOUNTING STANDARDS The Financial Accounting Standards Board (FASB) issued SFAS No. 141, "Business Combinations" and SFAS No. 142, "Goodwill and Other Intangible Assets" in June 2001. SFAS No. 141 establishes accounting and reporting standards for business combinations and requires all business combinations to be accounted for by the purchase method. The Statement is effective for all business combinations initiated after June 30, 2001, and any business combinations accounted for using the purchase method for which the date of acquisition is July 1, 2001, or later. SFAS No. 142 addresses accounting and reporting standards for goodwill and other intangible assets. Under the provisions of this Statement, goodwill and intangible assets with indefinite useful lives are no longer amortized, but will be tested annually for impairment. Matrix applied the new rules on accounting for goodwill and other intangible assets beginning June 1, 2002. Application of the nonamortization provisions of the Statement would have resulted in prior years basic and fully diluted earnings per share being $0.16 and $0.16 respectively. On August 31, 2002, Matrix completed the impairment tests of goodwill as of June 1, 2002. The results of these tests have indicated that there was no impairment impact in adopting this standard. The FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" in October, 2001. This Statement supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of," and amends Accounting Principles Board Opinion No. 30, "Reporting the Results of Operations- Reporting the Effects of Disposal of a Segment of a Business and Extraordinary, Unusual and Infrequently Occurring Events and Transactions." The Statement retains the basic framework of SFAS No. 121, resolves certain implementation issues of SFAS No. 121, extends applicability to discontinued operations, and broadens the presentation of discontinued operations to include a component of an entity. The Statement is being applied prospectively, beginning June 1, 2002. Initial adoption of the Statement did not have any impact on Matrix results of operations or financial position. NOTE F - DEBT At August 31, 2002, $8.4 million was outstanding under the Company's $20 million revolving bank credit agreement, with $7.0 million at a LIBOR interest rate of 2.81%, and $1.4 million at a prime interest rate of 3.625%. There was $11.6 million remaining in availability with $3.1 million utilized by outstanding letters of credit which mature in 2004. At August 31, 2002, the balance on the term loan stands at $5.5 million at a LIBOR interest rate of 3.89%. NOTE G - CONTINGENCIES As of August 31, 2002, accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts included revenues for unapproved change orders of approximately $0.6 million and claims of approximately $1.8 million. Generally, amounts related to unapproved change orders and claims will not be paid by the customer to Matrix until final resolution of related claims, and accordingly, collection of these amounts may extend beyond one year. -8-

The Company is currently in litigation in the Tulsa County district court for the State of Oklahoma over matters arising out of its worker's compensation program with a former insurance provider. These matters involve contests over certain collateral pledged to secure Matrix's obligations under this prior program. The defendants have filed a motion to transfer venue to the courts in Bermuda. A hearing on this motion and on whether current court ordered restraints on the collateral will remain in place is scheduled for October 30, 2002. The Company is not able to predict the outcome of this hearing. The Company is vigorously defending against this matter and it is the opinion of management that this legal action will not have a material effect on the Company's financial position. NOTE H - SUBSEQUENT EVENTS Under the terms of the August 31, 1999 Asset Sales Agreement between Matrix and Caldwell Tanks, Inc. ("Caldwell") relating to the sale of Brown Steel Constructors Inc. ("Brown"), Caldwell entered into a three-year lease agreement with an option to acquire for $1.7 million the real estate and buildings under lease. In August 2002, Caldwell indicated their intent to exercise the option to acquire the real estate and buildings. This sale closed on September 27, 2002. -9-

ITEM 2. Management's Discussion and Analysis of Financial Condition and Results of Operations. Forward Looking Statements Certain matters discussed in this report include forward-looking statements. Forward-looking statements can generally be identified or recognized as those statements predicated upon or preceded by words such as "believe," "expect", "plan", or "should" and like words of similar affect. Matrix is making these forward-looking statements in reliance on the "safe harbor" protections provided under the Private Securities Litigation Reform Act of 1995. Forward-looking statements are subject to a number of uncertainties that could cause actual results to differ materially from any results projected, forecasted, estimated, or budgeted, including the following: .. The timing and planning of maintenance projects at customer facilities in the refinery industry which could cause comparisons of results in one period to another to differ materially. .. Changes in general economic conditions in the United States. .. Changes in laws and regulations to which Matrix and its customers are subject, including tax, environmental, and employment laws and regulations which could cause increased costs to Matrix, a decline in customer demand for services designed to meet new laws and regulations and a decline in the amount of services outsourced by customers. .. The cost and effects of legal and administrative claims and proceedings against Matrix or its subsidiaries. .. Conditions of the capital markets Matrix utilizes to access capital to finance operations. .. The ability to raise capital in a cost-effective way. .. The effect of changes in accounting policies. .. The ability to manage growth and to assimilate personnel and operations of acquired businesses. .. The ability to control costs. .. Severe weather which could cause project delays and/or a decline in labor productivity. .. Changes in foreign economies, currencies, laws, and regulations, especially in Canada where Matrix has made direct investments. .. Political developments in foreign countries, especially in Canada where Matrix has made direct investments. .. The ability of Matrix to develop expanded markets and product or service offerings as well as its ability to maintain existing markets. .. The ability of Matrix to develop a learning curve in bidding and managing projects in a new industry. .. Technological developments, high levels of competition, lack of customer diversification, and general uncertainties of governmental regulation in the energy industry. .. The ability to recruit, train, and retain an adequate number of project supervisors with substantial experience. .. A downturn in the petroleum storage operations or hydrocarbon processing operations of the petroleum and refining industries. .. Changes in the labor market conditions that could restrict the availability of workers or increase the cost of such labor. .. The negative effects of a strike or work stoppage. .. Exposure to construction hazards related to the use of heavy equipment with attendant significant risks of liability for personal injury and property damage. -10-

.. The risk of using significant production estimates for determining percent complete on construction contracts could differ materially upon final determination of project scope. .. The inherent inaccuracy of estimates used to project the timing and cost of exiting operations of non-core businesses. .. Fluctuations in quarterly results. Results of Operations Consolidated Overview Matrix operates in three segments - AST Services, Construction Services and Plant Services. All operations are contained within these segments, therefore, significant fluctuations in gross revenues, gross profits, selling, general and administrative costs and operating income will be discussed below. Other income in the first quarter of 2003 consists largely of $0.2 million in proceeds from an insurance settlement for flood damage sustained in the previous year in Houston. The effective tax rates for the quarters ended August 31, 2002 and 2001 were 38.5% and 38.8% respectively. AST Services Fiscal Year 2003 vs. 2002 Gross revenues for AST Services in the quarter ended August 31, 2002 were $42.6 million, compared to $38.5 million in the comparable quarter of the prior year, an increase of $4.1 million or 10.6% due to a strong business environment in the western and eastern United States. Gross margins for the quarter ended August 31, 2002 of 13.4% were slightly worse than the 13.5% for the quarter ended August 31, 2001 as a direct result of tighter margins in our midwestern division. Increased sales volumes slightly offset by the margin declines resulted in gross profit for the quarter ended August 31, 2002 of $5.7 million exceeding the $5.2 million for the quarter ended August 31, 2001 by $0.5 million or 9.6%. Selling, general and administrative expense as a percent of revenues increased to 7.6% in the quarter ended August 31, 2002 vs. 7.1% in the quarter ended August 31, 2001 primarily due to higher fixed salary costs. Operating income and income before income tax expense for the quarter ended August 31, 2002 of $2.5 million and $2.7 million respectively, were similar to the $2.4 million and $2.3 million respectively produced for the quarter ended August 31, 2001, when excluding the insurance settlement discussed above. Construction Services Fiscal Year 2003 vs. 2002 Gross revenues for Construction Services in the quarter ended August 31, 2002 were $7.6 million, compared to $3.9 million in the comparable quarter of the prior year, an increase of $3.7 million or 94.9% due to continued business development efforts. Gross margins for the quarter ended August 31, 2002 of 11.8% were significantly better than the 7.7% produced for the quarter ended August 31, 2001 as a direct result of higher margin work. These margin improvements along with the increased sales volumes -11-

resulted in gross profit for the quarter ended August 31, 2002 of $0.9 million exceeding the $0.3 million for the quarter ended August 31, 2001 by $0.6 million or 200%. Operating income and income before income tax expense for the quarter ended August 31, 2002 of $0.5 million and $0.5 million respectively, were significantly better than the $0.0 million and $0.0 million respectively produced for the quarter ended August 31, 2001 primarily as a result of the higher gross profits discussed above. Plant Services Fiscal Year 2003 vs. 2002 Gross revenues for Plant Services in the quarter ended August 31, 2002 were $4.0 million, compared to $5.4 million in the comparable quarter of the prior year, a decrease of $1.4 million or (25.9)% due to lower maintenance and turnaround work in the first quarter of this year. Gross margins for the quarter ended August 31, 2002 of 0.0% were worse than the 7.4% produced for the quarter ended August 31, 2001 as a direct result of less absorption of fixed costs due to reduced volumes. These margin declines along with the decreased sales volumes resulted in gross profit for the quarter ended August 31, 2002 of $0.0 million falling short of the $0.4 million in gross profit for the quarter ended August 31, 2001. Operating income and income before income tax expense for the quarter ended August 31, 2002 of $(0.6) million and $(0.6) million respectively, were slightly worse than the $(0.3) million and $(0.4) million respectively produced for the quarter ended August 31, 2001. Financial Condition & Liquidity Matrix's cash and cash equivalents totaled approximately $1.0 million at August 31, 2002 and $0.8 million at May 31, 2002. Matrix has financed its operations recently with cash from operations and from advances under a credit agreement. Matrix has a credit agreement with a commercial bank under which a total of $20.0 million may be borrowed on a revolving basis based on the level of Matrix's eligible receivables and costs in excess of billings. Matrix can elect revolving loans which bear interest on a Prime or LIBOR based option and mature on October 31, 2004. At August 31, 2002, $8.4 million was outstanding under the revolver with $7.0 million at a LIBOR interest rate of 2.81%, and $1.4 million at a prime interest rate of 3.625%. There was $11.6 million remaining in availability with $3.1 million utilized by outstanding letters of credit which mature in 2004. The agreement requires maintenance of certain financial ratios, limits the amount of additional borrowings and the payment of dividends. The credit facility is secured by all accounts receivable, inventory, intangibles, certain real property, and proceeds related thereto. In fiscal 2002, the Company also borrowed $5.9 million under a term loan that matures June 6, 2006. The term loan is secured by a mortgage on certain facilities under construction at the Port of Catoosa in Oklahoma. The term loan bears interest at LIBOR + 1.5%. Effective June 1, 2001, the Company entered into an interest rate swap agreement for an initial notional amount of $6 million with a commercial bank, effectively providing a -12-

fixed interest rate of 7.23% for the five year period on the term note. The company will pay 7.23% and receive LIBOR + 1.5%, calculated on the notional amount. Net receipt or payments under the agreement will be recognized as an adjustment to interest expense. The related debt was initially drawn under the credit agreement revolving loan, and was rolled into the term loan on September 26, 2001. At August 31, 2002, the balance on the term loan stands at $5.5 million at a LIBOR interest rate of 3.89%. The swap agreement expires in 2006. If LIBOR decreases, interest payments received and the market value of the swap position decrease. Operations of Matrix used $0.5 million of cash for the three months ended August 31, 2002 as compared with $2.4 million of cash for the three months ended August 31, 2001, representing a decrease of approximately $1.9 million. The decrease was due primarily to higher net income and reduced working capital needs. Capital expenditures during the quarter ended August 31, 2002 totaled approximately $3.7 million. Of this amount, approximately $2.3 million was used in the construction of the Port of Catoosa facility, $0.2 million was used to purchase transportation equipment for field operations, and approximately $0.7 million was used to purchase welding, construction, and fabrication equipment. Matrix invested approximately $0.5 million in office equipment, computer hardware and software, and furniture and fixtures during the quarter. Matrix has budgeted approximately $15.8 million for capital expenditures for fiscal 2003 of which $7.3 million is included for the Tulsa Port of Catoosa construction. Matrix signed a 40-year lease for a 50-acre facility planned in Tulsa, Oklahoma in order to consolidate Matrix's four facilities in the Tulsa market now containing fabrication, operations and administration. Currently, the Tank Construction Division and Tulsa Regional office have relocated to the Port of Catoosa in a new 33,000 square foot facility and construction is in progress on the new 153,000 square foot fabrication facility . Matrix believes that its existing funds, amounts available from borrowings under its existing credit agreement and cash generated by operations will be sufficient to meet the working capital needs through fiscal 2003 and for the foreseeable time thereafter. The preceding discussion contains forward-looking statements including, without limitation, statements relating to Matrix's plans, strategies, objectives, expectations, intentions, and adequate resources, that are made pursuant to the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. Readers are cautioned that such forward-looking statements contained in the financial condition and liquidity section are based on certain assumptions, which may vary from actual results. Specifically, the capital expenditure projections are based on management's best estimates, which were derived utilizing numerous assumptions of future events, including the successful remediation of environmental issues relating to the Brown sale and other factors. However, there can be no guarantee that these estimates will be achieved, or that there will not be a delay in, or increased costs associated with, the successful remediation of the remaining Brown property. Outlook The current backlog in the Construction Services suggests that the second quarter will show stronger sales volumes and higher profitability. The performance experienced in Matrix's AST Services Division in the first quarter should continue as our customers' -13-

maintenance budgets are spent during the last four months of the calendar year. It is unclear, however, whether or not these maintenance budgets will be approved at levels comparable, greater, or lower in the upcoming calendar year of 2003 in light of the current state of uncertainty that exists. Environmental Matrix is a participant in certain environmental activities in various stages involving assessment studies, cleanup operations and/or remedial processes. In connection with the Company's sale of Brown and affiliated entities in 1999, an environmental assessment was conducted at Brown's Newnan, Georgia facilities. The assessment turned up a number of deficiencies relating to storm water permitting, air permitting and waste handling and disposal. An inspection of the facilities also showed friable asbestos that needed to be removed. In addition, Phase II soil testing indicated a number of volatile organic compounds, semi-volatile organic compounds and metals above the State of Georgia notification limits. Ground water testing also indicated a number of contaminants above the State of Georgia notification limits. Appropriate State of Georgia agencies have been notified of the findings and corrective and remedial actions have been completed, are currently underway, or plans for such actions have been submitted to the State of Georgia for approval on the remaining property. The current estimated total cost for cleanup and remediation is $2.1 million, $0.1 million of which remains accrued at August 31, 2002. Matrix closed or sold the business operations of its San Luis Tank Piping Construction Company, Inc. and West Coast Industrial Coatings, Inc. subsidiaries, which are located in California. Although Matrix does not own the land or building, it would be liable for any environmental exposure while operating at the facility, a period from June 1, 1991 to the present. At the present time, the environmental liability that could result from the testing is unknown, however, Matrix has purchased a pollution liability insurance policy with $5.0 million of coverage for all operations. Matrix has other fabrication operations in Tulsa, Oklahoma; Bristol, Pennsylvania; and Orange, California which could subject the Company to environmental liability. It is unknown at this time if any such liability exists, but based on the types of fabrication and other manufacturing activities performed at these facilities and the environmental monitoring that the Company undertakes, Matrix does not believe it has any material environmental liabilities at these locations. Matrix builds aboveground storage tanks and performs maintenance and repairs on existing aboveground storage tanks. A defect in the manufacturing of new tanks or faulty repair and maintenance on an existing tank could result in an environmental liability if the product stored in the tank leaked and contaminated the environment. Matrix currently has liability insurance with pollution coverage of $1 million, but the amount could be insufficient to cover a major claim. -14-
