LOS ANGELES – (BUSINESS WIRE) – November 18, 2025 – Tutor Perini Corporation (the "Company") (NYSE: TPC), a leading civil, building and specialty construction company, announced today that, in light of the Company’s strong third quarter and year-to-date 2025 results, which included record year-to-date operating cash flow of $574.4 million, of which $289.1 million was in the third quarter alone, and record backlog of $21.6 billion, the Company’s Board of Directors has declared a quarterly cash dividend of $0.06 per share and authorized a share repurchase program totaling $200 million.

Gary Smalley, Chief Executive Officer and President, said, “Our business is performing exceptionally well this year, and we recently increased our 2025 earnings guidance for the third consecutive quarter. As we continue to deliver outstanding operating results across all key metrics, including extraordinarily strong operating cash flow supported by an all-time record backlog of construction projects, our Board has determined that now is the right time to enhance our capital allocation strategy. With significant macroeconomic tailwinds based on solid customer demand and supported by tremendous amounts of federal, state and local level funding earmarked for infrastructure investments across the nation, Tutor Perini is well-positioned to generate significantly higher revenue and profit, as well as strong operating cash flow, in 2026 and 2027. As we look confidently to the future, our strategy is to combine this explosive period of growth with dividends and share repurchases to further reward our valued shareholders."

The $0.06 per share cash dividend will be payable on December 23, 2025, to all shareholders of record at the close of business on December 9, 2025. The Company currently expects that comparable cash dividends will be paid quarterly for the foreseeable future (an expected annualized dividend of $0.24 per share).

Under the $200 million share repurchase program, the Company plans to purchase outstanding common shares from time to time in open market transactions or through privately negotiated transactions at the Company’s discretion, subject to market conditions and other factors and at such times and in amounts that the Company deems appropriate.
