Perini Corporation Announces 2006 Results

•

Record revenues of $3.0 billion; record pretax income of $69.7 million

•

Net income of $41.5 million; diluted EPS of $1.54 per share

•

Backlog of $8.5 billion, up 7% from prior year end

Framingham, MA – February 15, 2007 – Perini Corporation (NYSE: PCR), a leading building, civil construction and construction management company, today reported results for the year ended December 31, 2006.

2006 Results

Net income was $41.5 million for the year ended December 31, 2006, as compared to net income of $4.0 million in 2005. Diluted earnings per common share were $1.54 for the year ended December 31, 2006, as compared to $0.20 for the year ended December 31, 2005. Revenues from construction operations were a record $3.0 billion for the year ended December 31, 2006, compared to revenues of $1.7 billion for the year ended December 31, 2005. The increase in revenues is due primarily to the addition of Rudolph and Sletten, and to an increased volume of work in the building segment’s hospitality and gaming market as a result of the significant new contract awards received in the latter half of 2005. Net income for the year ended December 31, 2006 was reduced by a $9.9 million after-tax charge, or $0.37 per diluted share, as a result of stock-based compensation expense from restricted stock unit awards granted in 2006. The 2005 results were severely impacted by an after-tax charge of $23.6 million, or $0.90 per diluted share, relating to the judgment against two Perini joint ventures in the matter of Mergentime Corporation, et al. vs. Washington Metropolitan Area Transit Authority (“WMATA”). The diluted earnings per share calculation for the year ended December 31, 2005 was favorably impacted by $0.09 per share due to the reversal of a portion of accumulated but unpaid dividends on the Company’s $21.25 Preferred Stock as a result of the settlement of the lawsuit brought by holders of the Company’s $21.25 Preferred Stock.

Robert Band, President and Chief Operating Officer, stated that, “We are pleased to report a record pretax profit for 2006, led by our building and our management services segments. Our strong backlog of $7.9 billion entering 2006 converted to revenue as expected during the year. In addition, we have added new work to our backlog during 2006 at a faster pace than our revenue burn-off, resulting in an increased backlog of $8.5 billion at December 31, 2006. Given the visibility provided from this backlog, we look forward to what we anticipate will be a record year in 2007 for revenues and earnings per share.”

Fourth Quarter Results

Net income was $19.3 million for the fourth quarter of 2006, as compared to fourth quarter net loss of $13.9 million in 2005. Diluted earnings per common share were $0.72 for the fourth quarter of 2006, as compared to a loss per common share of $0.45 for the fourth quarter of 2005. Revenues from construction operations were $944.3 million for the fourth quarter of 2006, compared to revenues of $603.2 million reported for the fourth quarter of 2005. The fourth quarter of 2006 results were reduced by a $2.4 million after-tax charge, or $0.09 per diluted share, as a result of stock-based compensation expense from restricted stock unit awards granted in 2006. As with the full year 2005

results, the fourth quarter of 2005 operating results were severely impacted by an after-tax charge of $23.6 million, or $0.89 per diluted share, as a result of the WMATA judgment. The diluted loss per share calculation for the fourth quarter of December 31, 2005 was favorably impacted by $0.09 per share due to the reversal of a portion of accumulated but unpaid dividends on the Company’s $21.25 Preferred Stock.

Backlog at $8.5 Billion

The backlog of uncompleted construction work at December 31, 2006 was $8.5 billion, a 7% increase from the backlog of $7.9 billion reported at December 31, 2005. The December 31, 2006 backlog includes new contract awards added during the fourth quarter of 2006 totaling $440 million which encompassed all of the Company’s operating segments, primarily the Company’s building segment which added approximately $172 million of additional work in the hospitality and gaming market in Las Vegas, Nevada, California and Maryland along with $122 million of various new awards at Rudolph and Sletten including the healthcare and high-tech markets, and $85 million in school construction work in Florida.

Financial Condition Remains Strong in 2006

The Company’s financial condition strengthened during the year ended December 31, 2006. Working capital increased to $194.0 million at December 31, 2006 from $153.3 million at December 31, 2005. The Company improved its solid base of shareholders’ equity to $243.9 million at December 31, 2006, reflecting the outstanding operating results achieved over the past five years. The Company expects to close in the next few days on a new $125.0 million credit facility that can be expanded to $175.0 million in the future. The Company believes its strong financial position and credit arrangements are more than sufficient to support the Company’s substantial backlog.

Outlook

Looking ahead to 2007, led by continued growth in its building segment and strong profit contributions from all of its operating segments, the Company affirms its initial guidance for 2007 revenues in the range of $3.8 to $4.0 billion and diluted earnings per share ranging from $2.00 to $2.20.
