Sylmar, CA – November 4, 2010 - Tutor Perini Corporation (NYSE: TPC)(the "Company"), a leading civil and building construction company, today reported results for the third quarter ended September 30, 2010.

Third Quarter and Nine Month Results

Revenues from construction operations were $731.8 million for the third quarter of 2010, as compared to revenues of $1.17 billion for the third quarter of 2009. Net income was $30.9 million for the third quarter of 2010, as compared to net income of $26.7 million for the third quarter of 2009. Diluted earnings per common share were $0.65 for the third quarter of 2010, as compared to diluted earnings per common share of $0.54 for the third quarter of 2009.

Revenues from construction operations were $2.51 billion for the first nine months of 2010, as compared to revenues of $4.07 billion for the first nine months of 2009. Net income was $84.6 million for the first nine months of 2010, as compared to net income of $104.6 million for the first nine months of 2009. Diluted earnings per common share were $1.73 for the first nine months of 2010, as compared to diluted earnings per common share of $2.13 for the first nine months of 2009.

Revenues for the third quarter and the first nine months of 2010 were reduced from the same periods in 2009 primarily as a result of the completion of large hospitality & gaming work during 2009; however, operating margins increased due to higher margin public works building and civil contracts.

At September 30, 2010, working capital was $351.2 million, an increase of $48.1 million from $303.1 million at December 31, 2009. The Company had $304.6 million in available borrowings at September 30, 2010. Subsequent to the quarter end, the Company completed a private placement offering of $300 million of 7.625% senior unsecured notes due November 1, 2018. The notes were priced at 99.258% of par, resulting in a yield to maturity of 7.75%. The Company believes its financial position and credit arrangements are sufficient to support the Company’s current backlog, anticipated new work and acquisition strategy.

Backlog

The backlog of uncompleted construction work at September 30, 2010 was approximately $4.0 billion compared to $4.3 billion at December 31, 2009.  Additions to new work during the third quarter of 2010 include the $300 million Aqueduct Racetrack casino in New York, a $25 million power plant in California and a $23 million educational facilities project in Arizona. The decrease in our backlog reflects the fluctuations and timing of the completion of existing work and awards of new work between quarters.

Outlook

The Company is confirming its 2010 guidance for diluted earnings per share at an estimated range of $2.00 to $2.20 per share and is lowering its guidance for 2010 revenues from an estimated range of $3.4 to $3.9 billion to an estimated range of $3.1 to $3.3 billion.  Due to a number of developing project opportunities, the Company plans to release guidance for 2011 during the 4th quarter 2010 conference call.

Ronald Tutor, Chairman and CEO, said: “Our overall results reflect the growing contribution from higher margin public works civil and building projects that have allowed us to be a stronger and more diversified company. We are also pleased to return value to our shareholders through the recently announced special cash dividend.  With the added capital

resulting from our $300 million senior notes offering, we have enhanced our ability to take advantage of growth opportunities through acquisitions available in the current market."
