PRESS RELEASE

ISSUED MAY 29, 2003

MATRIX SERVICE COMPANY PROVIDES

EARNINGS GUIDANCE FOR FISCAL YEAR 2004

TULSA, OK – May 29, 2003 – Matrix Service Co. (Nasdaq: MTRX), a leading industrial services company, today announces that it expects fully diluted earnings per share to be in a range of $1.50 to $1.65 for fiscal year 2004, which begins June 1, 2003. Consolidated revenues are projected to grow to between $475 million and $500 million for fiscal year 2004.

Brad Vetal, president and chief executive officer, said, “Although repair and maintenance activity remains soft, we anticipate the postponed demand for such repair and maintenance services, a strong construction market and the inclusion of the recently acquired Hake Group of Companies will drive the fiscal 2004 improvements.”

“We are pleased to note that Morgan Joseph & Co. and Sidoti & Co. have joined the list of securities firms that are currently following Matrix, which includes First Analysis Corp. and Huntleigh Securities.”
