LOS ANGELES – (BUSINESS WIRE) – November 5, 2025 – Tutor Perini Corporation (the "Company") (NYSE: TPC), a leading civil, building and specialty construction company, today reported strong results for the third quarter of 2025 (see attached tables).

Revenue for the third quarter of 2025 was $1.42 billion, up 31% compared to $1.08 billion for the same period in 2024. The Company delivered solid year-over-year growth across all three segments through the first nine months of 2025, primarily driven by increased project execution activities on certain newer, larger and higher-margin projects, all of which have significant scope of work remaining.

Revenue for the Civil and Specialty Contractors segments for the third quarter of 2025 was up 41% and 124%, respectively, compared to the same quarter last year. The Civil segment's revenue for both the third quarter and first nine months of 2025 were the segment's highest ever for the respective periods, as market demand for construction projects remains strong and the Company continues to capitalize on major bidding opportunities.

Income from construction operations for the third quarter of 2025 was $40.1 million, up significantly compared to a loss from construction operations of $106.8 million for the third quarter of 2024. The increase was principally due to higher-margin contributions related to the increased project execution activities discussed above, as well as the absence of certain net unfavorable adjustments that impacted results for the third quarter of 2024. The Company's income from construction operations for the third quarter of 2025 reflected a $42.2 million ($0.77 per diluted share) increase in share-based compensation expense compared to the third quarter of 2024, primarily due to continued growth in the Company’s stock price, which was up 171% year-to-date through the end of the third quarter of 2025, affecting the fair value of liability-classified awards.

Net income attributable to the Company for the third quarter of 2025 was $3.6 million, or EPS of $0.07, up substantially compared to net loss attributable to the Company of $100.9 million, or a $1.92 diluted loss per share, for the third quarter of 2024.

Adjusted net income attributable to the Company, which excludes the impact of share-based compensation expense, net of associated tax benefit, for the third quarter of 2025 was $61.9 million, or $1.15 of Adjusted EPS, compared to Adjusted net loss attributable to the Company, which also excludes the impact of share-based compensation expense, net of associated tax benefit, of $84.5 million, or $1.61 of Adjusted diluted loss per share, for the third quarter of 2024. Please refer to the Non-GAAP Financial Measures section below for further information and a reconciliation of the Company's financial results reported under generally accepted accounting principles in the United States (“GAAP”) to the reported adjusted results.

The Company generated $289.1 million of cash from operating activities in the third quarter of 2025 and $574.4 million in the first nine months of 2025, both of which set new records for each respective period, and both up significantly compared to $22.6 million and $174.0 million for the same periods last year. The Company's operating cash flow for the third quarter of 2025 was the second-highest result of any quarter. The record operating cash flow for the first nine months of 2025 was largely driven by collections from newer and ongoing projects and, to a much lesser extent, from collections related to recent dispute resolutions.

The Company expects strong annual operating cash flows to continue well beyond 2025.

The Company booked $2.0 billion of new awards and contract adjustments in the third quarter of 2025, demonstrating its ongoing success in capturing significant new project opportunities resulting from a combination of its strategic bidding approach and favorable market dynamics, including limited competition in certain markets for some of the largest, most complex projects. This environment, which is supported by strong public and private customer funding and demand, has allowed the Company to differentiate itself and deliver compelling proposals that align with customers' goals and expectations.

As a result of the strong new awards activity, the Company's backlog grew to a new record of $21.6 billion as of September 30, 2025, up 54% compared to the backlog at the end of the third quarter of 2024. Backlog for the Building and Specialty Contractors segments as of September 30, 2025 also set new records. The most significant new awards and contract adjustments in the third quarter of 2025 included:

•A healthcare facility project in California valued at approximately $1 billion;

•A $182 million military defense project in Guam;

•A $155 million education facility project in California;

•Four mechanical projects in Florida collectively valued at $123 million;

•$53 million of additional funding for a mass-transit project in California; and

•$51 million of additional funding for another healthcare project in California.

The Company expects its backlog will remain strong due in part to certain Building segment projects currently in the preconstruction phase that are anticipated to advance to the construction phase later this year and in 2026 and 2027. Tutor Perini expects to continue bidding selectively on various project opportunities that will drive long-term shareholder value. The Company continues to have significant project bidding opportunities, particularly on the West Coast, in the Midwest, and in the Indo-Pacific region, and remains well positioned to continue winning its share of new projects over the next several years.

Total debt as of September 30, 2025 was $413 million, down 23% compared to $534 million at the end of 2024. As a result of the record operating cash flow in the third quarter and year-to-date in 2025, the Company's cash exceeded its total debt by $283 million as of September 30, 2025, maintaining the Company's balance sheet in a strong net cash position. In addition, the Company's balance of costs and estimated earnings in excess of billings ("CIE") was $848 million as of September 30, 2025, down $95 million, or 10%, compared to the balance at the end of 2024 and at the lowest level it has been since the second quarter of 2017.

This reduction in CIE was primarily driven by the resolution and billing of various previously disputed matters.

"Tutor Perini's third-quarter results were outstanding across all key metrics and demonstrate our continued business momentum and success in delivering solid operating performance, with healthy profit margins in the Civil and Building segments and a return to profitability in the Specialty Contractors segment," said Gary Smalley, Tutor Perini's Chief Executive Officer and President.

"We are benefiting from favorable macroeconomic tailwinds, which are driving strong market demand for construction services across all our segments. We remain focused on capitalizing on a range of attractive bidding opportunities, which resulted in Tutor Perini securing $2 billion of new awards this quarter, increasing our backlog to a new record of $21.6 billion. We continue to expect the long-duration and higher-margin nature of projects in backlog to translate into significantly higher revenue and earnings over the next several years."

"Our record operating cash flow for the first nine months of 2025 is already well in excess of last year's full-year record cash flow, and we expect to continue generating strong cash flow for the rest of this year and beyond. Furthermore, our earnings to date are considerably higher than expected, enabling us to confidently raise our full-year earnings guidance for the third consecutive quarter," added Mr. Smalley.

Tutor Perini's business has continued to perform extremely well through the first nine months of 2025, and the Company anticipates solid operating performance and financial results over the rest of this year, with significantly higher revenue and earnings still expected in 2026 and 2027 as various newer large projects advance to the construction phase.

Based on the Company's excellent year-to-date results in 2025 and management's increased confidence in its performance trajectory for the remainder of the year, the Company is raising its 2025 Adjusted EPS guidance, with Adjusted EPS now expected in the range of $4.00 to $4.20 (up from $3.65 to $3.95). Based on current projections, the Company continues to expect that Adjusted EPS for 2026 and 2027 will be significantly higher than the upper end of its increased 2025 guidance. The Company's increased guidance continues to factor in a significant amount of contingency for various unknown or unexpected developments in 2025 and beyond.

The Company is no longer providing forward-looking guidance for GAAP EPS or a quantitative reconciliation of Adjusted EPS guidance to GAAP EPS guidance because of the inherent difficulty in forecasting share-based compensation expense, which fluctuates with future share price movements, without unreasonable efforts. Variations in share-based compensation expense could have a material impact on GAAP reported results for the guidance period.

The Company continues to see strong demand for its services, driven by well-funded state, local and federal customers that have numerous large-scale, high-priority infrastructure projects planned over the next several years, as well as by certain commercial customers that continue to advance projects for new or renovated buildings in vibrant end markets, such as healthcare, education, and hospitality and gaming.

Tutor Perini still does not currently anticipate any significant impacts from recently imposed tariffs, the curtailment of federal funding for certain projects, or the recent federal government shutdown, but continues to closely monitor these issues.

To supplement our unaudited condensed consolidated financial statements presented under GAAP, we are presenting certain non-GAAP financial measures. These non-GAAP financial measures are intended to provide additional insights that facilitate the comparison of our past and present performance, and they are among the indicators management uses to assess the Company’s financial performance and to forecast future performance.

By including these non-GAAP financial measures, we aim to provide investors and stakeholders a clearer understanding of our operating results and enhance transparency with respect to the key financial metrics used by our management in its financial and operational decision-making.

These non-GAAP financial measures, which exclude share-based compensation expense (as well as the tax benefit associated with the expense), include adjusted net income (loss) attributable to the Company and adjusted earnings (loss) per share. We exclude share-based compensation expense because this expense could result in significant volatility in our reported earnings, driven primarily by fluctuations in the expense recognized for certain long-term incentive compensation awards with payouts that are indexed to the Company’s common stock. By adjusting for share-based compensation, our non-GAAP measures present a supplemental depiction of our operational performance and financial health. This approach allows stakeholders to focus on our core operational efficiency and profitability without the variable impact to earnings caused by significant changes in our stock price. Our non-GAAP measures are intended to offer a consistent basis for evaluating the Company’s performance, which management believes is meaningful to stakeholders.

The non-GAAP financial measures included in this earnings release as calculated by the Company are not necessarily comparable to similarly titled measures reported by other companies. Additionally, these non-GAAP financial measures are not meant to be considered as indicators of performance in isolation from or as a substitute for the most directly comparable measures prepared in accordance with GAAP and should be read only in conjunction with financial information presented on a GAAP basis.

Reconciliations of these non-GAAP financial measures are found in the table below:

(a)The amount represents share-based compensation expense recorded during the three and nine months ended September 30, 2025 and 2024. This includes expense associated with certain long-term incentive compensation awards that have payouts indexed to the Company’s common stock. As such, significant fluctuations in the price of the Company’s common stock during any reporting period have caused and could continue to cause significant fluctuations in the reported expense. The increase in the expense for the three and nine months ended September 30, 2025 as compared to the prior-year periods was driven by the substantial increase in the price of the Company’s stock during the 2025 periods.
