Sterling Reports First Quarter 2025 Results and Increases Full Year Guidance

THE WOODLANDS, TX – May 5, 2025 – Sterling Infrastructure, Inc. (NasdaqGS: STRL) (“Sterling” or the “Company”) today announced financial results for the first 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 are on an adjusted, pro forma basis to exclude RHB. Please see the "Historical Quarterly Backlog Information” section below for reconciliations to historical figures.

First Quarter 2025 Results

•Revenues of $430.9 million. Revenues increased 7% excluding RHB from the prior year quarter.

•Gross margin of 22.0%, up from 17.5%

•Net income of $39.5 million, or $1.28 per diluted share, increases of 27% and 28%, respectively

•Adjusted net income(1) of $50.2 million, or $1.63 per diluted share, increases of 28% and 29%, respectively

•EBITDA(1) of $72.1 million, an increase of 30%

•Adjusted EBITDA(1) of $80.3 million, an increase of 31%

•Cash flows from operations totaled $84.9 million

•Cash and cash equivalents totaled $638.6 million at March 31, 2025

•Backlog at March 31, 2025 was $2.13 billion

•Combined backlog(2) at March 31, 2025 was $2.23 billion

Drake Concrete Acquisition

During the first quarter of 2025, Sterling closed on the acquisition of Drake Concrete, LLC, a provider of concrete slabs for residential home builders in the Dallas-Fort Worth market. The acquisition strengthens Sterling’s geographic footprint within the DFW metroplex and expands and deepens the customer base, given limited customer overlap with Tealstone. Sterling anticipates that Drake will contribute approximately $55 million of revenue and $6.5 million in adjusted EBITDA in 2025. The purchase price was $25 million in cash plus a four year earn-out opportunity. Drake will be included in the Building Solutions segment.

CEO Remarks and Outlook

“Sterling is off to a great start in 2025, as we grew our first quarter adjusted net income by 28% to deliver adjusted diluted EPS of $1.63,” stated Joe Cutillo, Sterling’s Chief Executive Officer. “Revenue growth in the quarter was a solid 7%, on a pro forma basis, fueled by strong 18% growth in E-Infrastructure Solutions and 9% growth in Transportation Solutions. Gross profit margins in the quarter of 22% remained extremely strong as we have shifted the business toward higher-margin service offerings, and contributed to adjusted EBITDA growth of 31%.”

Mr. Cutillo continued, “We ended the quarter with backlog of $2.1 billion, a 17% increase compared to the prior year first quarter on a like-for-like basis. Our book-to-burn ratio in the quarter was 2.2x. Notably, E-Infrastructure Solutions had

(2) Combined Backlog includes Unsigned Awards of $103.2 million at March 31, 2025.

another strong quarter for awards, as backlog reached over $1.2 billion and grew 27% compared to the prior year. Additionally, our pipeline of high-probability future phase work continues to grow. Our operating cash flow generation in the first quarter was again excellent at $85 million, driving our net cash position to $329 million, and supporting share repurchases of $44 million.”

Mr. Cutillo added, “In E-Infrastructure Solutions, we achieved 18% revenue growth and 61% adjusted operating income growth in the first quarter as adjusted operating margins expanded nearly 618 basis points to reach 23.2%. 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. The data center market remains very active and now represents over 65% of E-Infrastructure backlog.

Transportation Solutions revenue increased 9% and adjusted operating income grew 60%. We continue to see good 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 benefit margins as we move through 2025.

In Building Solutions, revenue declined 14% and adjusted operating income declined 18%. Our residential businesses continued to be impacted by the slowdown in the housing market, as prospective homebuyers are facing affordability challenges. Additionally, weather conditions were unusually severe in the quarter. We remain bullish on the multi-year demand trends in our key geographies.”

“We believe 2025 will be another excellent 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 quarter performance, backlog, and the impact of share repurchases. The midpoint of our revised 2025 guidance would represent 12% revenue growth pro forma for the new RHB accounting methodology, 22% adjusted diluted earnings per share growth and 23% adjusted EBITDA growth,” Mr. Cutillo concluded.

Full Year 2025 Guidance

•Revenue of $2.05 billion to $2.15 billion

•Net Income of $222 million to $239 million

•Diluted EPS of $7.15 to $7.65

•EBITDA(1) of $381 million to $403 million

Full Year 2025 Adjusted Guidance

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 $262 million to $278 million

•Adjusted Diluted EPS(1) of $8.40 to $8.90

•Adjusted EBITDA(1) of $410 million to $432 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.

2Sterling | STRL: First Quarter 2025 DISCLOSURE: Forward-Looking Statements This presentation contains, and the officers and directors of the Company may from time to time make, statements that are considered forward- looking statements within the meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934. 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 presentation, 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 presentation 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 presentation 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. This presentation may contain the financial measures: adjusted net income, EBITDA, adjusted EBITDA, and adjusted EPS, which are not calculated in accordance with U.S. GAAP. When presented, a reconciliation of the non-GAAP financial measures to the most directly comparable GAAP financial measure will be provided in the Appendix to this presentation.
