Sterling Reports Record Fourth Quarter and Full Year 2024 Results
Provides Full Year 2025 Guidance
THE WOODLANDS, TX – February 25, 2025 – Sterling Infrastructure, Inc. (NasdaqGS: STRL) (“Sterling” or the “Company”) today announced financial results for the fourth quarter and full year 2024 and provided full year 2025 guidance.
The financial comparisons herein are to the prior year quarter, unless otherwise noted.
Due to the deconsolidation of our RHB joint venture on December 31, 2024, RHB is not included in year-end 2024 consolidated backlog. As such, our prior-year comparisons for these metrics are on an adjusted basis to exclude RHB. Please see the "Historical Quarterly Backlog Information” section below for reconciliations to historical figures.
Fourth Quarter 2024 Results
•Revenues of $498.8 million, an increase of 3%
•Gross margin of 21.4%, up from 18.9%
•Net income of $113.2 million, or $3.64 per diluted share, an increase of 182% and 184% respectively
•Excluding the impact of a one-time gain on the deconsolidation of a subsidiary and acquisition-related costs, net income was $45.5 million, or $1.46 per diluted share, an increase of 12% and 13%, respectively
•EBITDA(1) of $167.4 million, an increase of 145%
•Adjusted EBITDA(1) of $76.4 million, an increase of 11%
•Cash flows from operations totaled $497.1 million for the twelve months ended December 31, 2024
•Cash and cash equivalents totaled $664.2 million at December 31, 2024
•Backlog at December 31, 2024 was $1.69 billion
•Combined backlog(2) at December 31, 2024 was $1.83 billion
For the full year ended December 31, 2024, revenue increased by 7% over 2023. The Company reported net income of $257.5 million, or $8.27 per diluted share in 2024, versus $138.7 million, or $4.44 per diluted share, in 2023. Adjusted net income(1) increased 36.3% to $189.9 million, or $6.10 per diluted share in 2024, versus $139.3 million, or $4.46 per diluted share, in 2023. EBITDA(1) increased 59% to $410.9 million in 2024, versus $259.0 million in 2023. Adjusted EBITDA(1) increased 23% to $320.0 million in 2024, versus $259.9 million in 2023.
CEO Remarks and Outlook
“2024 was another record year for Sterling as we grew our adjusted net income by 36% to deliver diluted EPS of $6.10, which was above the high end of our previously guided range,” stated Joe Cutillo, Sterling’s Chief Executive Officer. “Additionally, our gross margins exceeded 20% on an annual basis, a new record, and we generated nearly $500 million of operating cash flow.”
Mr. Cutillo continued, “In the fourth quarter we delivered 3% revenue growth and a 13% increase in adjusted diluted EPS. Our focus on margin expansion continues to drive profitability growth well in excess of revenue growth, and we expect this

trend to continue in 2025. Gross profit margins in the quarter of 21.4% remained extremely strong as we have shifted the business toward higher-margin service offerings.
We closed the year with combined backlog of $1.83 billion, which was up slightly from prior year levels on a like-for-like basis. Notably, E-Infrastructure Solutions backlog reached over $1 billion and grew 27% relative to the prior year. Additionally, award activity has been strong in the first quarter of 2025 and our pipeline of high-probability future phase work continues to grow. Our operating cash flow generation in the fourth quarter of 2024 was again excellent at $174 million, driving our net cash position to $348 million, and supporting share repurchases of $20 million.”
Mr. Cutillo added, “In E-Infrastructure Solutions, we achieved 50% operating income growth in the fourth quarter as operating margins expanded nearly 700 basis points to reach 24.1%. 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.
E-Infrastructure revenue increased 8% compared to the prior year quarter, driven by strength in data center work. Notably, data center-related revenue increased over 50% compared to the prior year quarter and now represents over 60% of segment backlog.
Transportation Solutions revenue increase d 24% for the full year and operating margins were 6.5%. In the fourth quarter, revenue and operating income declined against a challenging comparison to 4Q23 which benefited from very favorable weather and project timing. We continue to see good demand and project opportunities in our core Rocky Mountain and Arizona regions. We have made the strategic decision to accelerate our shift away from low bid heavy highway work in Texas, which will weigh on revenue and backlog in the near term, but will benefit margins as we move through 2025.
In Building Solutions, full year 2024 revenue increased 1.1% and operating income increased 6.3%. In the quarter, revenue declined 3% and operating income declined 17%. The decline in operating income is entirely attributable to $1.8 million of earn-out expense related to the acquisition of PPG. Our residential businesses continued to be impacted by the slowdown in the Dallas-Fort Worth market, as prospective homebuyers are facing affordability challenges. We remain bullish on the multi-year demand trends in our key geographies and are cautiously optimistic of a rebound in the second half of 2025.”
“We believe 2025 will be another excellent year for Sterling as we continue to drive bottom line growth that outpaces top line growth. The midpoint of our 2025 guidance would represent 10% revenue growth pro forma for the new RHB accounting methodology, 18% adjusted net income growth and 18% adjusted EBITDA growth,” Mr. Cutillo concluded.
Full Year 2025 Guidance
•Revenue of $2.00 billion to $2.15 billion
•Net Income of $215 million to $230 million
•Diluted EPS of $6.75 to $7.25
•EBITDA(1) of $370 million to $395 million
Full Year 2025 Non-GAAP Guidance
Sterling is introducing new non-GAAP methodology for 2025 that includes new adjustments for non-cash stock-based compensation and amortization of intangible assets. In addition, we are expanding our definition of acquisition related costs to include earn-outs. Please see the “Adjusted Net Income Guidance Reconciliation” and “EBITDA Guidance Reconciliation” sections below for reconciliations of GAAP to non-GAAP measures and comparable 2024 results.
•Adjusted Net Income(1) of $252 million to $267 million
•Adjusted Diluted EPS(1) of $7.90 to $8.40
•Adjusted EBITDA(1) of $395 million to $420 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 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: 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.
