TRC ANNOUNCES FOURTH-QUARTER AND YEAR-END FISCAL 2008 FINANCIAL RESULTS

Lowell, MA, September 29, 2008 - TRC Companies, Inc. (NYSE: TRR), a recognized leader in engineering, consulting, and construction management, today announced financial results for the fourth quarter and fiscal year ended June 30, 2008.

Fourth-Quarter Results

For the three months ended June 30, 2008, gross revenue increased 7 percent to $122.5 million compared with $115.0 million for the three months ended June 30, 2007.  Net service revenue for the fourth quarter of fiscal 2008 increased 2 percent to $65.2 million from $63.9 million for the fourth quarter of fiscal 2007.  The Company believes net service revenue, rather than gross revenue, best reflects the value of services provided to its customers and is a more accurate indicator of TRC’s revenue performance.

Net loss applicable to common shareholders for the three months ended June 30, 2008 was $16.1 million, or $0.86 per common share, compared with a net loss applicable to common shareholders of $4.3 million, or $0.23 per common share, for the comparable period in fiscal 2007.  Net loss applicable to common shareholders for the fourth quarter of fiscal 2008 was primarily consisted of a restructuring charge of approximately $3.2 million, legal expenses of $4.4 million, $6.9 million of losses on two large projects and asset impairment charges of approximately $1.6 million.

Comments on the Fourth-Quarter

“From a top-line perspective, TRC achieved 7 percent growth in gross revenue and 2 percent growth in net service revenue,” said Chairman and Chief Executive Officer Chris Vincze.  “Three of our core markets – energy, environmental and infrastructure – continued to add to our growth despite the ongoing economic turmoil and TRC’s turnaround program, indicating a strong client following in our core markets.  During the fourth quarter, the services provided in the energy and environmental markets were the strongest contributors to our net service revenue while our services to the infrastructure and real estate markets also contributed in the quarter.”

“Infrastructure project financing appeared to face significant challenges at times, but we benefited from the presence of several new highway projects in both the western and mid-Atlantic areas of the U.S.,” said Vincze.  “Overall, we remain well positioned with an excellent reputation and established brand in our key markets.  Our three primary markets are still growing and have positive long-term outlooks.  As a result, we are continuing to maintain a significant backlog.”

“Operationally, the fourth quarter was a challenging period for us as early on we experienced unusually high legal expenses, as well as losses from two large projects,” Vincze said.  “As the quarter progressed, we accelerated some of our turnaround and cost reduction activities, resulting in a greater than expected operating loss.”

“During the quarter, we took aggressive steps to right-size the business by further reducing our head count, consolidating certain office locations, and exiting some underperforming businesses,” said Vincze.  “The reduced cost structure stemming from the restructuring actions will provide costs savings in the next fiscal year as we build momentum for a return to profitability.  We also improved the health of our balance sheet by improving our accounts receivable related cash flow and reducing the level of debt outstanding under our revolving credit facility.”

“With our Vision enterprise resource planning platform operational, we can now better monitor financial performance and manage projects – improving our ability to directly manage costs and reducing the risk of performance surprises going forward,” said Vincze.

Fiscal Year 2008 Results

For the fiscal year ended June 30, 2008, gross revenue increased 5 percent to $465.1 million from $441.6 million for fiscal 2007.  Net service revenue for fiscal 2008 grew 5 percent to $268.2 million from $255.9 million for the comparable period in 2007.

Net loss applicable to common shareholders for fiscal 2008 was $109.1 million, or $5.84 per common share, compared with a net loss applicable to common shareholders of $5.9 million, or $0.33 per common share, for fiscal 2007.  In addition to the $16.1 million of fourth-quarter charges discussed above, the net loss applicable to common shareholders for fiscal 2008 included charges of $88.8 million consisting of a $76.7 million goodwill impairment charge and a $12.1 million charge to provide a full valuation allowance against our net deferred tax assets.

Comments on the Full-Year

“Fiscal 2008 represented the second year of our three-year turnaround strategy,” Vincze said.  “During the year, we continued to increase our revenues as we capitalized on opportunities within our most promising markets.  Given the substantial level of operational changes we implemented during the year, our growth reflects the unwavering focus of our employees on addressing the needs of our customers.  Overall, we were disappointed with our financial results for fiscal 2008.  However, we made considerable progress in improving our cost structure and our operating platform, which is now established as a solid foundation for profitable growth.”

Business Outlook

“TRC today is in a much better position as a result of our efforts in fiscal 2008,” said Vincze.  “While our actions clouded our financial performance for the year, we enter fiscal 2009 as a far healthier and leaner organization with significant opportunities in the energy, environmental and infrastructure markets.”

“Our goal for fiscal 2009 is to successfully complete our turnaround plan and expand upon our market opportunities,” said Vincze.  “To achieve our goals, our primary initiatives for the year include improving project profitability and performance; maintaining positive operating cash flow; expanding our service lines through prospective and existing clients; and continuing to attract and retain a top-tier workforce while continuing our cost reduction efforts.  We expect to see significantly improved results in the quarters ahead.”

You can identify these statements by forward-looking words such as “may,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” or other words of similar import.
