Framingham, MA – August 7, 2007 – Perini Corporation (NYSE: PCR), a leading building, civil construction and construction management company, today reported results for the second quarter ended June 30, 2007.

Second Quarter Results

Revenues from construction operations were $1.15 billion for the second quarter of 2007, as compared to revenues of $712 million reported for the second quarter of 2006. The increase in revenues is due primarily 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 $27.6 million for the second quarter of 2007, as compared to second quarter net income of $4.6 million in 2006. Diluted earnings per common share were $1.01 for the second quarter of 2007, as compared to $0.16 for the second quarter of 2006.

Robert Band, President and Chief Operating Officer, stated that, “We are pleased to report the largest quarter for revenues and net income in the 113-year history of the Company, led again by our building and management services segments. The increase in our revenues and profit continues to primarily reflect the conversion of our substantial building segment backlog into revenues and profit as anticipated. In addition, our backlog of $8.7 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.”

Six Month Results

Revenues from construction operations were $2.14 billion for the first six months of 2007, as compared to revenues of $1.33 billion for the first six months of 2006. The increase in revenues is due primarily 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.

For the first six months of 2007, net income was $50.2 million, as compared to $12.7 million for the first six months of 2006. Diluted earnings per common share were $1.84 for the first six months of 2007, as compared to $0.46 for the first six months of 2006.

Backlog at $8.7 Billion

The backlog of uncompleted construction work at June 30, 2007 was $8.7 billion, a 2.6% increase from the backlog of $8.5 billion reported at December 31, 2006. The June 30, 2007 backlog includes new contract awards and adjustments to contracts in process added during the second quarter of 2007 totaling $1.3 billion, which includes approximately $960 million of additional work in the hospitality and gaming market in Las Vegas and California, as well as approximately $300 million in various new awards at Rudolph & Sletten including the healthcare and office building markets.

Financial Condition Remains Strong in 2007

The Company’s financial condition remained strong at June 30, 2007. Working capital increased to $235.8 million at June 30, 2007, from $194.0 million at December 31, 2006. The Company improved its solid base of shareholders’ equity to $306.3 million at June 30, 2007. In addition, the Company has $113.5 million available to borrow under its credit facility at June 30, 2007. The Company believes its strong financial position and credit arrangements are adequate to support its substantial backlog.

Outlook

As a result of the strong performance in the first six months by the building and management services segments, the Company is increasing its guidance for 2007 revenues from a range of $4.0 to $4.2 billion to a range of $4.1 to $4.3 billion, and diluted earnings per share from a range of $2.40 to $2.60 to a range of $2.80 to $3.00.
