Framingham, MA – May 8, 2007 – Perini Corporation (NYSE: PCR), a leading building, civil construction and construction management company, today reported results for the first quarter ended March 31, 2007.

First Quarter Results

Revenues from construction operations were $987.4 million for the first quarter of 2007, compared to revenues of $612.8 million for the first quarter of 2006. The increase in revenues is primarily due to an increased volume of work in the hospitality and gaming market as a result of the significant new contract awards received in the latter half of 2005 which are now well into the construction phase.

Net income was $22.7 million for the first quarter of 2007, as compared to net income of $8.1 million for the first quarter of 2006. Diluted earnings per common share were $0.84 for the first quarter of 2007, as compared to $0.30 for the first quarter of 2006.

Robert Band, President and Chief Operating Officer, stated that, “We are pleased to report a strong performance for the first quarter of 2007, led by our building and management services segments. The increase in our revenues and profit primarily reflects the conversion of our substantial building segment backlog into revenues and profit as anticipated, and an exceptionally strong management services segment performance resulting in a significant contribution to our first quarter operating results. In addition, our backlog of $8.6 billion remains near its all-time record level. Given the visibility provided from this backlog, we continue to look forward to what we anticipate will be a record year in 2007 for revenues and earnings per share.”

Backlog at $8.6 Billion

The backlog of uncompleted construction work at March 31, 2007 was $8.6 billion, up from the $8.5 billion backlog reported at December 31, 2006. The March 31, 2007 backlog includes new contract awards added during the first quarter of 2007 totaling approximately $1.1 billion, which includes approximately $580 million of additional work in the hospitality and gaming market in Las Vegas, as well as approximately $435 million of various new awards at Rudolph and Sletten including the healthcare, high-tech and office building markets.

Financial Condition Remains Strong in 2007

The Company’s financial condition remained strong at March 31, 2007. Working capital increased to $203.4 million at March 31, 2007, from $194.0 million at December 31, 2006. The Company improved its solid base of shareholders’ equity to $271.3 million at March 31, 2007. In addition, the Company has $113.5 million available to borrow under its new expanded credit facility at March 31, 2007. The Company believes its strong financial position and credit arrangements are more than adequate to support its substantial backlog.

Outlook

Based on the strong first quarter performance, the Company increases its guidance for 2007 revenues from a range of $3.8 to $4.0 billion to a range of $4.0 to $4.2 billion, and diluted earnings per share from a range of $2.00 to $2.20 to a range of $2.40 to $2.60.
