(3) The Company recorded a tax benefit related to the release of the income tax valuation allowance during the fourth quarter of fiscal 2013.

Comments on the Results

“TRC's strategy to drive profitable growth and performance excellence was demonstrated by our strong performance in fiscal 2013,” said Chris Vincze Chairman and Chief Executive Officer. “We finished the year with 10% NSR growth for the fourth quarter and a 6% overall increase for the year. The growth in the

fourth quarter was split nearly evenly between organic and acquisition related revenues. Net income for the quarter was positively affected by a federal and state income tax benefit of $18.7 million. This benefit was due to the release of the deferred tax asset valuation allowance that had been in place since 2008 and is the result of our consistent financial performance over the past three years.

“Our two largest segments, Energy and Environmental, continue to contribute much of the growth on our top line, while the continued profitability of our Infrastructure segment helped bolster the bottom line for the fourth quarter. Increased activity from our utility clients as they upgrade and replace electric distribution and transmission systems drove the 10% NSR increase in our Energy segment. In our Environmental segment, NSR grew by 8%, primarily as a result of new work on several remediation projects. Our Infrastructure segment also saw an NSR increase of 8%, due to modestly improved general market conditions. Efficient management of projects and revenue growth drove a 40% increase in our Infrastructure segment profit. Higher levels of project activity in our Energy and Environmental segments resulted in 5% and 10% profit growth, respectively.”

Business Outlook

“The outlook for each of TRC's three market segments continues to be positive. While the general economic picture is varying and lacking consistent positive trends, we are seeing some capital spending materialize with respect to the utility and power distribution markets as well as bridge and road construction and upgrades. Our $247 million NSR backlog is correspondingly up 5% in the fourth quarter compared with the same quarter of the prior year driven by the 23% NSR backlog increase in our Infrastructure segment. We believe our continued ability to expand TRC's geographic presence and successfully expand key client relationships for electric distribution engineering and energy efficiency services will drive growth in our Energy segment. Air and water regulation, development of natural gas pipelines and environmental management and sustainability investments are expected to create new opportunities for project work within our Environmental segment. Proposal activity for state transportation projects has been increasing in our Infrastructure segment, and we are involved with several projects to repair and upgrade bridges and roads across the country.

“TRC will continue to invest in growth opportunities including acquisitions, key account expansion, and enhanced initiatives focused on the power and oil and gas markets. We have a strong cash position, healthy balance sheet and an enhanced credit facility that provides us with flexibility to invest in our growth. Given this foundation, in the coming year we expect to further our mission to become a top tier financial performer in the engineering, consulting and construction management space,” concluded Vincze.
