Sterling Reports Record Third Quarter 2024 Results

and Raises Full Year Profitability Guidance

THE WOODLANDS, TX – November 6, 2024 – Sterling Infrastructure, Inc. (NasdaqGS: STRL) (“Sterling” or the “Company”) today announced financial results for the third quarter 2024.

The financial comparisons herein are to the prior year quarter, unless otherwise noted.

Third Quarter 2024 Results

•Revenues of $593.7 million, an increase of 6%

•Gross margin of 21.9%, up from 16.4%

•Net Income of $61.3 million, or $1.97 per diluted share, an increase of 56% for both metrics

•EBITDA(1) of $100.8 million, an increase of 42%

•Cash flows from operations totaled $322.8 million for the nine months ended September 30, 2024

•Cash and Cash Equivalents totaled $648.1 million at September 30, 2024

•Backlog at September 30, 2024 was $2.06 billion

•Combined backlog(2) at September 30, 2024 was $2.37 billion

CEO Remarks and Outlook

“In the third quarter we delivered 6% revenue growth and a remarkable 56% increase in diluted EPS. Our focus on margin expansion continues to drive profitability growth well in excess of revenue growth. Gross profit margins of 21.9% marked a new record, and we continue to look for opportunities to drive further expansion,” stated Joe Cutillo, Sterling’s Chief Executive Officer. “We closed the third quarter with combined backlog of $2.37 billion, which was in line with prior year levels. What the backlog metrics do not capture is that our business has moved toward large, multi-phase projects. As a result, we have built a pipeline of high probability future phase work that now totals over half a billion dollars. Our operating cash flow generation in the quarter was again excellent at $152 million, driving our net cash position to $326 million, and supporting share repurchases of $20 million in the quarter. Our business is performing very well and we feel great about the opportunities ahead.”

Mr. Cutillo continued, “In E-Infrastructure Solutions, we achieved 89% operating income growth as operating margins expanded over 1,100 basis points to reach 25.8%. This excellent margin profile reflects our shift toward large mission-critical projects, including data centers and manufacturing. E-Infrastructure revenue increased 4% in the quarter, driven by strength in data center work, which more than offset a tough revenue comparison in the manufacturing market and some continued softness in the small project market. Notably, data center-related revenue increased approximately 90% in the quarter and now represents over 50% of segment backlog.

Transportation Solutions had another excellent quarter, delivering 18% revenue growth and 28% operating profit growth. The transportation markets are the strongest that they have been in our company’s history, and we still have two and a half years remaining under the Infrastructure Investment and Jobs Act (IIJA) authorization.

(1) See the “Non-GAAP Measures” and “EBITDA Reconciliation” sections below for more information.

(2) Combined Backlog includes Unsigned Awards of $319.6 million at September 30, 2024.

In Building Solutions, revenue declined 10% and operating profit declined 12%. Our residential concrete slab and plumbing businesses were impacted by a slowdown in the Dallas market in the quarter, as prospective homebuyers appear to be waiting on the sidelines in expectation of future interest rate reductions. We remain very bullish on the multi-year demand trends in our key geographies and anticipate a rebound in 2025.”

“We believe 2024 will be another excellent year for Sterling. Given our strong results through the third quarter and backlog position, we are raising our full year profitability guidance. The midpoint of our 2024 guidance would represent 10% revenue growth, 32% net income growth and 21% EBITDA growth,” Mr. Cutillo concluded.

Full Year 2024 Guidance

•Revenue of $2.150 billion to $2.175 billion

•Net Income of $180 million to $185 million

•Diluted EPS of $5.85 to $6.00

•EBITDA(1) of $310 million to $315 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.
