NEWS RELEASE

For Immediate Release:

May 1, 2023

Sterling Reports Record First Quarter 2023 Results

THE WOODLANDS, TX – May 1, 2023 – Sterling Infrastructure, Inc. (NasdaqGS: STRL) (“Sterling” or the “Company”) today announced financial results for the first quarter 2023.

The financial information herein is from continuing operations and comparisons are to the prior year quarter, unless otherwise noted.

First Quarter 2023 Results

•Revenues of $403.6 million, an increase of 10%

•Gross margin of 15.3%, an increase from 15.1%

•Net Income of $19.6 million, or $0.64 per diluted share, an increase of 11% and 8%, respectively

•EBITDA(1) of $45.9 million, an increase of 14%; Adjusted EBITDA(1) of $46.1 million, an increase of 13%

•Cash flows from operations of $49.1 million for the first quarter

•Cash and Cash Equivalents totaled $202.6 million at March 31, 2023

•Backlog at March 31, 2023 was $1.62 billion, an increase of 15% over December 31, 2022

•Combined backlog(2) at March 31, 2023 was $1.75 billion, an increase of 4% over December 31, 2022

CEO Remarks and Outlook

“Our first quarter results reflect excellent execution from our teams despite the ongoing economic challenges. Our performance drove strong revenue growth of 10% and gross margin expansion of 20 basis points, yielding first quarter EPS of $0.64,” stated Joe Cutillo, Sterling’s Chief Executive Officer.

“E-Infrastructure Solutions, our largest, fastest-growing and highest-margin segment, grew 22%. This reflects high levels of demand from data center and advanced manufacturing customers. Our Transportation Solutions segment saw a 4% decline in revenue due to the reallocation of resources into higher-margin E-Infrastructure work and the timing of project execution. Our continued efforts to improve mix drove an increase in Transportation Solutions operating income of 19%. Our Building Solutions segment grew revenue by 7%, reflecting higher levels of commercial revenue. Our residential revenues were essentially flat despite a mid-single digit decline in slab volumes. Buildings Solutions margins were lower relative to the prior year quarter due to mix impacts, as we anticipated,” continued Mr. Cutillo.

“Our year is off to a strong start with record backlog, new high-value E-Infrastructure project awards, increased transportation funding, and emerging improvement in housing starts. Our solid first quarter results and the favorable growth opportunities across our markets give us confidence that we are trending toward the higher end of our guidance range. The high end of our guidance ranges would offer an improvement in revenue by 13.0% and net income by 13.7% over 2022,” Mr. Cutillo concluded.

(1) The Company defines EBITDA as GAAP net income from Continuing Operations, adjusted for depreciation and amortization, net interest expense and taxes. The Company defines Adjusted EBITDA as EBITDA excluding acquisition related costs. See the “Non-GAAP Measures” and “EBITDA Reconciliation” sections below for more information.

(2) Combined Backlog includes Unsigned Awards of $130.5 million and $275.0 million at March 31, 2023 and December 31, 2022, respectively.

Full Year 2023 Guidance

•Revenue of $1.9 billion to $2.0 billion

•Net Income of $104 million to $110 million

•EPS of $3.33 to $3.53

•EBITDA(1) of $220 million to $235 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 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; 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,” “should,” “expect,” “plan,” “project,” “intend,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “pursue,” “target,” “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 2023 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,” “should,” “expect,” “plan,” “project,” “intend,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “pursue,” “target,” “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. If 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.
