TRC ANNOUNCES THIRD-QUARTER FISCAL 2008 FINANCIAL RESULTS

Lowell, MA, May 22, 2008 - TRC (NYSE: TRR), a recognized leader in engineering, consulting and construction management, today announced financial results for the third quarter of fiscal 2008.

Third-Quarter Results

For the three months ended March 28, 2008, gross revenue decreased 3% to $108.0 million compared with $111.5 million for the three months ended March 31, 2007.  Net service revenue for the third quarter of fiscal 2008 increased to $65.5 million from $64.1 million for the third 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 the Company’s revenue performance.

Net loss applicable to common shareholders for the three months ended March 28, 2008 was $4.9 million, or $0.26 per common share, compared with a net loss applicable to common shareholders of $0.7 million, or $0.04 per common share, for the comparable period in fiscal 2007.  Results for the three months ended March 28, 2008 include an unusually high level of legal costs of $3.8 million.

Nine Months Ended March 28, 2008

For the nine months ended March 28, 2008, gross revenue increased 5% to $342.6 million from $326.7 million for the nine months ended March 31, 2007.  Net service revenue for the nine months ended March 28, 2008 grew 6% to $203.1 million from $192.0 million for the comparable period in 2007.

Net loss applicable to common shareholders for the nine months ended March 28, 2008 was $93.0 million, or $4.99 per common share, compared with a net loss applicable to common shareholders of $1.6 million, or $0.09 per common share, for the comparable period in fiscal 2007.  Net loss applicable to common shareholders for the first nine months of fiscal 2008 includes a loss of $88.8 million related to a goodwill impairment

charge and a tax provision to provide a full valuation allowance against net deferred tax assets.  Excluding the effect of those charges, TRC would have incurred a net loss applicable to common shareholders of $4.2 million for the first nine months of fiscal 2008.

Comments on Results

“We continued to make operational progress during the fiscal third quarter, which is historically a weaker quarter due to seasonality,” said Chris Vincze, TRC’s Chairman and Chief Executive Officer.  “During the third quarter, our energy and environmental sectors drove net service revenue growth and we continued to implement actions designed to further reduce costs and improve long-term margins.”

“Our cost reduction efforts implemented over the past several months should result in approximately $5 million in annualized savings,” said Vincze.  “We anticipate implementing additional cost reductions in the fourth quarter. We also have several strategic initiatives in place focused on improving utilization and pricing strategies, which we expect will have a positive impact on our ability to achieve profitable growth. “

Outlook

“We incurred some significant charges in the third quarter and we are well aware of the challenges we face in completing the transformation of the organization,” said Vincze.  “Nevertheless, we remain encouraged by the measurable progress we are making on a number of important operational fronts as we pursue our goal of optimizing the organization in 2009.”

“We continue to focus on our goals of revenue growth with sustainable profitability and continued cost reduction.  We are now into the second half of our three-year turnaround.  At this point, TRC has been rebuilt, reorganized and restrategized.  With our Vision reporting platform in place, we have better visibility into the business, and we now expect faster and more effective execution going forward.  Our focus for the fourth quarter and into fiscal 2009 will be on pricing, utilization improvement, project management and cost reduction.  For the long term, we remain confident in the promising markets in which we operate,” concluded Vincze.

Forward-Looking Statements

Certain statements in this press release may be forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. You can identify these statements by forward-looking words such as “may,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” or other words of similar import. You should consider statements that contain these words carefully because they discuss our future expectations, contain projections of our future results of operations or of our financial condition, or state other “forward-looking” information. We believe that it is important to communicate our future expectations to our investors. However, there may be events in the future that we are not able to accurately predict or control and that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. Investors are cautioned that all forward-looking statements involve risks and uncertainties, and actual results may differ materially from those discussed as a result of various factors, including, but not limited to, the availability and adequacy of insurance; the uncertainty of our operational and growth strategies; regulatory uncertainty; the availability of funding for government projects; the level of demand for our services; product acceptance; industry-wide competitive factors; the ability to continue to attract and retain highly skilled and qualified personnel; recent changes in our  senior management; the results of outstanding litigation; risks arising from either failure to identify, or from identified material weaknesses in our internal controls over financial reporting or our inability to effectively remedy such weaknesses; our inability to comply with the terms of our credit facility and our lenders’ future unwillingness to waive our noncompliance; and general political or economic conditions.  Furthermore, market trends are subject to changes, which could adversely affect future results. See additional discussion in our Annual Report on Form 10-K for the fiscal year ended June 30, 2007, Quarterly Reports on Form 10-Q, and other factors detailed from time to time in our other filings with the Securities and Exchange Commission.
