Sterling Reports Record Second Quarter 2025 Results and Increases Full Year Guidance

THE WOODLANDS, TX – August 4, 2025 – Sterling Infrastructure, Inc. (NasdaqGS: STRL) (“Sterling” or the “Company”) today announced record financial results for the second quarter of 2025.
The financial comparisons herein are to the prior year quarter, unless otherwise noted.
Due to the deconsolidation of the RHB joint venture on December 31, 2024, RHB is no longer included in consolidated revenue or backlog. As such, prior-year comparisons for these metrics have been adjusted to exclude RHB. Please see the "Historical Quarterly Backlog Information” section below for reconciliations to historical figures.
Second Quarter 2025 Results
•Revenues of $614.5 million. Revenues increased 21% excluding RHB from the prior year quarter
•Gross margin of 23.3%, up from 19.3%
•Net income of $71.0 million, or $2.31 per diluted share, increases of 37% and 38%, respectively, and a new second quarter record.
•Adjusted net income(1) of $82.8 million, or $2.69 per diluted share, increases of 39% and 41%, respectively
•EBITDA(1) of $116.2 million, an increase of 34% and a new second quarter record.
•Adjusted EBITDA(1) of $125.6 million, an increase of 35%
•Cash flows from operations totaled $170.3 million for the six months ended June 30, 2025
•Cash and cash equivalents totaled $699.4 million at June 30, 2025
•Backlog at June 30, 2025 was $2.01 billion. The book-to-burn ratio for the six months ended June 30, 2025 was 1.4x.
•Combined backlog(2) at June 30, 2025 was $2.25 billion. The book-to-burn ratio for the six months ended June 30, 2025 was 1.5x.
Acquisition Update
On June 17th, Sterling announced that it had reached an agreement to acquire all of the assets of CEC Facilities Group LLC (“CEC”), and the transaction continues to progress towards closing. Sterling’s expectations for CEC’s full year performance are unchanged. Sterling’s updated guidance figures included in this earnings release do not include any contribution from CEC.
CEO Remarks and Outlook
“Our outstanding second quarter results reflect the strength and resilience of our portfolio, as we delivered very strong top line growth of 21% and even better bottom-line growth, with adjusted diluted earnings per share reaching $2.69, a 41% increase,” stated Joe Cutillo, Sterling’s Chief Executive Officer. “Revenue growth was again fueled by strong 29% growth in E-Infrastructure Solutions and 24% growth in Transportation Solutions, which more than offset softness in the Building Solutions market. Gross profit margins in the quarter of 23% marked a new high for the company, as we have shifted the business toward higher-margin service offerings. The combination of strong revenue growth and gross margin expansion contributed to adjusted EBITDA growth of 35%.”
(1) See “Non-GAAP Measures”, “Adjusted Net Income Reconciliation”, and “EBITDA Reconciliation” sections below for more information.
(2) Combined Backlog includes Unsigned Awards of $237.3 million at June 30, 2025.

Mr. Cutillo continued, “We ended the quarter with backlog of $2.0 billion, a 24% increase compared to the prior year second quarter on a like-for-like basis. Our book-to-burn ratio in the quarter was 0.8x, reflecting the strong backlog burn in the quarter combined with the typical seasonal lull in Transportation awards in the second quarter. Notably, E-Infrastructure Solutions awards remained strong in the quarter, outpacing the strong backlog burn. The combination of our signed backlog and high-probability future phase work continues to give us visibility into a pool of E-Infrastructure work approaching $2 billion. Our operating cash flow generation in the second quarter was again excellent at $85 million, driving our net cash position to $401 million.”
Mr. Cutillo added, “In E-Infrastructure Solutions, we achieved 29% revenue growth and 57% adjusted operating income growth in the second quarter as adjusted operating margins expanded over 500 basis points to reach 28.3%. This excellent margin profile reflects our shift toward large, mission-critical projects, including data centers and manufacturing, where our scale, superior execution, and track record of delivering projects on time are extremely valuable to our customers. Notably, awards in the E-Commerce distribution space increased meaningfully in the quarter. Large, mission-critical work continues to make up the majority of our backlog.
We are very excited about our previously announced agreement to acquire CEC. We continue to believe that the combination of CEC’s leading electrical services to high-growth markets including semiconductor and data center and Sterling’s best-in-class site civil infrastructure services will allow us to accelerate project timelines and become even more valuable to our customers. Additionally, we believe CEC will help accelerate our geographic expansion into Texas.
Transportation Solutions revenue increased 24% and adjusted operating income grew 78%. We continue to see solid demand and project opportunities in our core Rocky Mountain and Arizona regions. The downsizing of our low-bid Texas heavy highway business is progressing to plan. This shift will weigh on revenue and backlog in the near term, but will continue to benefit margins as we move through 2025.
In Building Solutions, revenue declined 1% and adjusted operating income declined 28%. Our residential businesses continued to be impacted by the slowdown in the housing market, as prospective homebuyers are facing affordability challenges. We remain bullish on the multi-year demand trends in our key geographies, but expect soft market conditions to persist in the near term.”
“We believe 2025 will be another record year for Sterling as we continue to drive bottom line growth that outpaces top line growth. We are raising our 2025 guidance to reflect our strong first half performance, backlog, and visibility into future phase opportunities. The midpoints of our revised 2025 guidance would represent 13% revenue growth as adjusted for RHB, 32% adjusted diluted earnings per share growth and 30% adjusted EBITDA growth,” Mr. Cutillo concluded.
Full Year 2025 Guidance
•Revenue of $2.10 billion to $2.15 billion
•Net Income of $243 million to $252 million
•Diluted EPS of $7.87 to $8.13
•EBITDA(1) of $406 million to $421 million

Important Information for Investors and Stockholders
Non-GAAP Measures
This press release contains “Non-GAAP” financial measures as defined under Regulation G of the amended U.S. Securities Exchange Act of 1934. The Company reports financial results in accordance with U.S. generally accepted accounting principles (“GAAP”), but the Company believes that certain Non-GAAP financial measures provide useful supplemental information to investors regarding the underlying business trends and performance of the Company’s ongoing operations and are useful for period-over-period comparisons of those operations.
Non-GAAP measures may include adjusted net income, adjusted operating income, adjusted EPS, EBITDA and adjusted EBITDA, in each case excluding the impacts of certain identified items. The excluded items represent items that the Company does not consider to be representative of its normal operations. The Company believes that these measures are useful for investors to review, because they provide a consistent measure of the underlying financial results of the Company’s ongoing business and, in the Company’s view, allow for a supplemental comparison against historical results and expectations for future performance. Furthermore, the Company uses each of these to measure the performance of the Company’s operations for budgeting and forecasting, as well as for determining employee incentive compensation. However, Non-GAAP measures should not be considered as substitutes for net income, EPS, or other data prepared and reported in accordance with GAAP and should be viewed in addition to the Company’s reported results prepared in accordance with GAAP.
Reconciliations of Non-GAAP financial measures to the most comparable GAAP measures are provided in the tables included within this press release.



Cautionary Statement Regarding Forward-Looking Statements
This press release contains statements that are considered forward-looking statements within the meaning of the federal securities laws. These forward-looking statements are subject to a number of risks and uncertainties, many of which are beyond our control, which may include statements about: the financial estimates or projections of CEC and the anticipated closing date and benefits of the potential acquisition; our business strategy; our financial strategy; our industry outlook; our guidance; our expected margin growth; and our plans, objectives, expectations, forecasts, outlook and intentions. All of these types of statements, other than statements of historical fact included in this press release, are forward-looking statements. In some cases, forward-looking statements can be identified by terminology such as “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “project,” “intend,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “pursue,” “target,” “guidance,” “continue,” the negative of such terms or other comparable terminology. The forward-looking statements contained in this press release are largely based on our expectations, which reflect estimates and assumptions made by our management. These estimates and assumptions reflect our best judgment based on currently known market conditions and other factors. Although we believe such estimates and assumptions to be reasonable, they are inherently uncertain and involve a number of risks and uncertainties that are beyond our control. In addition, management’s assumptions about future events may prove to be inaccurate. Management cautions all readers that the forward-looking statements contained in this press release are not guarantees of future performance, and we cannot assure any reader that such statements will be realized or the forward-looking events and circumstances will occur. Actual results may differ materially from those anticipated or implied in the forward-looking statements due to factors listed in the “Risk Factors” section in our filings with the U.S. Securities and Exchange Commission and elsewhere in those filings. Additional factors or risks that we currently deem immaterial, that are not presently known to us or that arise in the future could also cause our actual results to differ materially from our expected results. Given these uncertainties, investors are cautioned that many of the assumptions upon which our forward-looking statements are based are likely to change after the date the forward-looking statements are made. The forward-looking statements speak only as of the date made, and we undertake no obligation to publicly update or revise any forward-looking statements for any reason, whether as a result of new information, future events or developments, changed circumstances, or otherwise, notwithstanding any changes in our assumptions, changes in business plans, actual experience or other changes. These cautionary statements qualify all forward-looking statements attributable to us or persons acting on our behalf.
