(NasdaqGS: STRL) (“Sterling” or the “Company”) today announced strong financial results for the second quarter of 2026. The financial comparisons herein are to the prior year quarter, unless otherwise noted. Second Quarter 2026 Results: • Revenues of $1.17 billion increased by 90%. Acquisitions contributed $250.8 million of revenue in the quarter. • Net income of $155.8 million, or $5.00 per diluted share, increases of 120% and 116% respectively. • EBITDA of $233.6 million, an increase of 101%. Adjusted Results: • Adjusted net income of $180.8 million, or $5.80 per diluted share, increases of 118% and 116%, respectively. • Adjusted EBITDA of $256.7 million, an increase of 104%. Additional Financial Metrics: • Cash flows from operations totaled $328.0 million for the six months ended June 30, 2026. • Cash and cash equivalents totaled $464.5 million at June 30, 2026. • Backlog at June 30, 2026 was $4.33 billion, up 116% from the prior year period. Backlog increased 50% year-over-year on an organic basis. • Combined Backlog at June 30, 2026 was $5.62 billion, up 150% from the prior year period. Combined backlog increased 36% year-over-year on an organic basis. • Second quarter 2026 book-to-burn ratios were 1.4x for Backlog and 1.3x for Combined Backlog, exclusive of the impact of the Stone Ridge acquisition. CEO Remarks and Outlook “We delivered an outstanding second quarter, with adjusted net income increasing 118% to deliver adjusted diluted EPS of $5.80. Revenue grew 90%, including organic growth of approximately 50%, and strong adjusted EBITDA margins of 22%. Year-to-date operating cash flow generation totaled $328 million,” stated Joe Cutillo, Sterling’s Chief Executive Officer. “These results are a testament to the outstanding execution of our teams across the organization, and we are incredibly proud of their continued performance.” “Demand across our end markets remains strong, as reflected in robust bidding and award activity during the quarter and continued expansion of our multi-year visibility. We ended the quarter with signed backlog of $4.3 billion, up 116%, and combined backlog of $5.6 billion, up 150%. In addition, our pipeline of high-probability future phase work continues to (1) (2) (2) (2) (3) Acquisitions includes CEC and Stone Ridge.

expand and now exceeds $1.4 billion. Collectively, our signed backlog, unsigned awards, and future phase opportunities provide visibility into a total addressable pool of work of more than $7.0 billion, an increase of more than $2.5 billion since year-end 2025.” Mr. Cutillo continued, “Looking more closely at our segment performance, E-Infrastructure Solutions delivered another outstanding quarter, with revenue increasing 192% and adjusted operating income growing 148%. These results were driven by strong performance across both organic and acquired operations. The legacy site development business generated 111% revenue growth, reflecting significant growth across all regions, and operating margins expanded both year-over-year and sequentially. Demand for CEC’s electrical services also remained exceptionally strong, with revenue increasing 140% compared to the pre-acquisition second quarter and margins improving on both a year-over-year and sequential basis. E-Infrastructure signed backlog increased 165% over the prior year quarter. Mission-critical projects—including data centers, manufacturing, and semiconductor facilities—represented 92% of E-Infrastructure backlog at quarter end. We continue to see significant opportunities for both Sterling’s best-in-class site development services and CEC’s mission-critical electrical services, reinforcing our confidence in the multi-year growth trajectory of this business. In Transportation Solutions, revenue declined 20% compared to the prior year period, while adjusted operating income increased 8%. The revenue decline reflects our ongoing reallocation of resources from transportation projects to higher- margin E-Infrastructure opportunities; this shift is now taking place at an accelerated pace. In Building Solutions, revenue declined 1%, reflecting relatively flat levels of homebuilder activity, while adjusted operating income decreased 11%. We expect market conditions to remain challenging through 2026 as housing affordability pressures continue to affect prospective homebuyers, but remain optimistic on the long-term growth opportunities in our key geographies.” “Our strong second quarter results strengthen our conviction that 2026 will be another exceptional year for Sterling. As a result, we are raising our 2026 guidance to reflect the momentum across our businesses, the continued expansion of our backlog and future phase opportunities, our increasing visibility into future growth, and the contribution from the Stone Ridge acquisition. At the midpoint, our 2026 guidance would represent 64% year-over-year revenue growth, 84% growth in adjusted diluted earnings per share, and 79% growth in adjusted EBITDA—positioning Sterling for another year of exceptional execution, profitable growth, and long-term value creation,” Mr. Cutillo concluded. Full Year 2026 Guidance • Revenue of $4.00 billion to $4.15 billion • Net Income of $536 million to $555 million • Diluted EPS of $17.25 to $17.85 • EBITDA of $829 million to $854 million Full Year 2026 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 2025 results. • Adjusted Net Income of $612 million to $631 million • Adjusted Diluted EPS of $19.70 to $20.30 • Adjusted EBITDA of $891 million to $916 million (1) (1) (1) (1) See “Non-GAAP Measures”, “Adjusted Net Income Guidance Reconciliation” and “EBITDA Guidance Reconciliation” sections below for more information.(1)

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.

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.
