Tutor Perini Corporation (NYSE:TPC) (the "Company"), a leading civil, building and specialty construction company, announced today that it is offering $400 million aggregate principal amount of senior notes due 2033 (the "Notes") in a private offering. The Notes will be senior unsecured obligations of the Company and will be guaranteed by each of its wholly owned domestic subsidiaries that guarantee its revolving credit facility.

The Company intends to use the net proceeds from this offering, together with cash on hand, to redeem $400 million aggregate principal amount of its 11.875% Senior Notes due April 30, 2029 (the "2029 Notes") and pay related premiums, accrued interest and fees and expenses associated with such redemption. The Company may temporarily invest amounts that are not immediately needed for these purposes in cash or cash equivalents or other short-term investments, including marketable securities.

The Notes and related guarantees are being offered only to persons reasonably believed to be qualified institutional buyers in reliance on an exemption from registration pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"), and outside the United States in accordance with Regulation S under the Securities Act. The Notes and related guarantees have not been, and will not be, registered under the Securities Act, or the securities laws of any other jurisdiction, and may not be offered or sold in the United States without registration or an applicable exemption from registration requirements.

This press release does not constitute a redemption notice with respect to the 2029 Notes and shall not constitute an offer to sell or the solicitation of an offer to buy the Notes and the related guarantees, nor shall there be any sale of the Notes and the related guarantees in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction. Any offers of the Notes and related guarantees will be made only by means of a private offering circular.
