Item 2.02 Results of Operations and Financial Condition.

On July 28, 2026, Orion Group Holdings, Inc. (the “Company”) issued a press release announcing its financial results for the second quarter ended June 30, 2026. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.

The information contained in this Item 2.02 to the Company’s Current Report on Form 8-K, including Exhibit 99.1 attached hereto, is being furnished and shall not be deemed “filed” for any purpose, and shall not be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Securities Exchange Act of 1934, as amended  (the “Exchange Act”), except as expressly set forth by specific reference in such filing.

Use of Non-GAAP Financial Information

To help understand the Company’s financial performance, the Company has supplemented its financial results that it provides in accordance with generally accepted accounting principles (“GAAP”) with non-GAAP financial measures. Such financial measures include Adjusted Net Income (Loss), Adjusted Earnings (Loss) Per Common Share, earnings before interest, taxes, depreciation and amortization (“EBITDA”), Adjusted EBITDA, and Adjusted EBITDA Margin.

We believe these non-GAAP financial measures are frequently used by investors, securities analysts and other parties in the evaluation of our performance and liquidity with that of other companies in our industry. Management uses these measures to evaluate our operating performance, liquidity and capital structure. In addition, our incentive compensation plan measures performance based on our consolidated EBITDA, along with other factors. The methods we use to produce these non-GAAP financial measures may differ from methods used by other companies. These measures should be considered in addition to, not as a substitute for, financial measures prepared in accordance with GAAP. Applicable reconciliations to the nearest GAAP financial measure of each non-GAAP financial measure are included in the attached Exhibit 99.1.

Item 7.01 Regulation FD Disclosure.

On July 29, 2026, the Company posted the second quarter 2026 investor presentation to its website. The presentation is attached as Exhibit 99.2 to this Current Report on Form 8-K and is incorporated herein by reference. All information included in the presentation is presented as of the dates indicated, and the Company does not assume any obligation to correct or update such information in the future. In addition, the Company disclaims any inferences regarding the materiality of such information that may arise as a result of it furnishing such information under Item 7.01 of this Current Report on Form 8-K.

The information contained in this Item 7.01, including Exhibit 99.2 attached hereto, is being furnished and shall not be deemed “filed” for any purpose, and shall not be deemed incorporated by reference in any filing under the Securities Act or the Exchange Act, except as expressly set forth by specific reference in such filing.

ORION GROUP HOLDINGS REPORTS

SECOND QUARTER 2026 RESULTS

HOUSTON – July 28, 2026 – Orion Group Holdings, Inc. (NYSE: ORN) (the “Company” or “Orion”), a leading specialty construction company, today reported its financial results for the second quarter ended

June 30, 2026, and updated its full-year 2026 outlook.

Highlights for the quarter ended June 30, 2026

Revenue of $221.9 million, GAAP net loss of $4.1 million, or $0.10 per diluted share, Adjusted EBITDA of $7.9 million and Adjusted EPS of $0.02 per diluted share
Booked awards and change orders of $277 million; book-to-bill of 1.25X in the quarter
Reset full-year 2026 guidance

“In the quarter, Orion delivered solid year-over-year revenue growth and project bookings, reflecting favorable demand in our end markets. Our confidence in the long-term opportunities across our Marine and Concrete businesses remains robust, and our pipeline of opportunities has grown to approximately $27 billion. Recent awards across both of our businesses reinforce our competitive position in attractive end markets, spanning defense infrastructure, port and transportation infrastructure, data centers, healthcare and advanced manufacturing. With a growing opportunity pipeline, expanded capabilities, and an outstanding team delivering projects that matter, our conviction in Orion's long-term growth trajectory is strong,” said Travis Boone, Chief Executive Officer of Orion.

“Our Concrete business posted excellent results reporting over 30% revenue growth and over 45% adjusted EBITDA growth in the quarter benefitting from expansion of site civil services, favorable utilization and solid execution. Marine contract revenue and adjusted EBITDA were down primarily due to the timing of project start-ups and lower equipment utilization, and we have reset our full year 2026 guidance accordingly.  Today, we have strong visibility into the remainder of the year with nearly 90% of Marine work under contract and strong Concrete momentum to achieve our updated guidance,” concluded Boone.

Contract revenues of $221.9 million in the second quarter of 2026 increased $16.6 million, or 8%, from $205.3 million in the second quarter of last year. The increase was driven by the Concrete segment, reflecting strong demand, new project awards and higher volumes. This increase was partially offset by a reduction in Marine revenue, primarily attributable to the timing of project start-ups due to client-related issues such as site readiness and timing of delivery of client-provided materials.

Gross profit was $22.9 million in the second quarter of 2026, a decrease of $2.9 million, or 11%, from $25.8 million in the second quarter of 2025. The decrease was primarily driven by lower Marine volume and equipment utilization. The decrease was partially offset by favorable project execution within the Concrete segment.

Selling, general and administrative expenses were $24.4 million for the second quarter of 2026, up from $22.8 million in the second quarter of last year, primarily attributable to costs to support business growth.

GAAP net loss for the quarter ended June 30, 2026 was $4.1 million, or $0.10 per diluted share, compared to net income of $0.8 million, or $0.02 per diluted share, in the second quarter of last year.  

Adjusted EBITDA for the second quarter of 2026 was $7.9 million, compared to $11.0 million in the second quarter of 2025.

Non-GAAP Financial Measures

This press release includes the financial measures “adjusted net income/loss,” “adjusted earnings/loss per share,” “EBITDA,” “Adjusted EBITDA,” and “Adjusted EBITDA margin.”  These measurements are determined by methods other than in accordance with U.S. generally accepted accounting principles (“GAAP”) and are “non-GAAP financial measures” under rules of the U.S. Securities and Exchange Commission, including Regulation G. The non-GAAP financial information may be determined or calculated differently by other companies that use similarly titled measures. By reporting such non-GAAP financial information, the Company does not intend to give such information greater prominence than comparable GAAP financial information. Investors are urged to consider these non-GAAP measures in addition to and not in substitute for measures prepared in accordance with GAAP.

Adjusted net income/loss and adjusted earnings/loss per share should not be viewed as an equivalent financial measure to net income/loss or earnings/loss per share. Adjusted net income/loss and adjusted earnings/loss per share exclude certain items that management believes are one-time items or items whose timing or amount cannot be reasonably estimated. The Company believes these adjusted financial measures are a useful supplement to earnings/loss calculated in accordance with GAAP.

Orion defines EBITDA as net income/loss before net interest expense, income taxes, depreciation and amortization. Adjusted EBITDA is calculated by adjusting EBITDA for certain items that management believes are one-time items or items whose timing or amount cannot be reasonably estimated, such as non-cash share-based compensation, enterprise resource planning implementation, severance, process improvement initiatives and acquisition and integration costs. Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA for the period by contract revenues for the period. The GAAP financial measure that is most directly comparable to EBITDA and Adjusted EBITDA is net income, while the GAAP financial measure that is most directly comparable to Adjusted EBITDA margin is operating margin, which represents operating income divided by contract revenues. EBITDA, Adjusted EBITDA and Adjusted EBITDA margin are used internally to evaluate current operating expense, operating efficiency, and operating profitability on a variable cost basis, by excluding the depreciation and amortization expenses, primarily related to capital expenditures and acquisitions, and net interest and tax expenses. Additionally, EBITDA, Adjusted EBITDA and Adjusted EBITDA margin provide useful information regarding the Company's ability to meet future debt service and working capital requirements while providing an overall evaluation of the Company’s financial condition. In addition, EBITDA is used internally for incentive compensation purposes. The Company includes EBITDA, Adjusted EBITDA and Adjusted EBITDA margin to provide transparency to investors as they are commonly used by investors and others in assessing performance. EBITDA, Adjusted EBITDA and Adjusted EBITDA margin have certain limitations as analytical tools and should not be used as a substitute for operating margin, net income, cash flows, or other data prepared in accordance with GAAP, or as a measure of the Company’s profitability or liquidity.

Forward-Looking Statements

The matters discussed in this press release may constitute or include projections or other forward-looking statements within the meaning of the “safe harbor” provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, of which provisions the Company is availing itself. Certain forward-looking statements can be identified by the use of forward-looking terminology, such as “believes,” ”expects,” “may,” ”will,” ”could,” ”should,” ”seeks,” ”approximately,” ”intends,” “plans,” ”estimates,” or “anticipates,” or the negative thereof or other comparable terminology, or by discussions of strategy, plans, objectives, intentions, estimates, forecasts, guidance, outlook, assumptions, or goals. In particular, statements regarding our pipeline of opportunities, achievement of strategic priorities, position for growth, financial guidance and future operations or results, including those set forth in this press release, and any other statement, express or implied, concerning financial guidance or future operating

results or the future generation of or ability to generate revenues, income, net income, gross profit, EBITDA, Adjusted EBITDA, Adjusted EBITDA margin, or cash flow, including to service debt or maintain compliance with debt covenants, and including any estimates, guidance, forecasts or assumptions regarding future revenues or revenue growth, are forward-looking statements. Forward-looking statements also include project award announcements, estimated project start dates, ramp-up of contract activity and contract options, which may or may not be awarded in the future. Forward-looking statements involve risks, including those associated with the Company's fixed price contracts that impacts profits, unforeseen productivity delays that may alter the final profitability of the contract, cancellation of the contract by the customer for unforeseen reasons, delays or decreases in funding by the customer, levels and predictability of government funding or other governmental budgetary constraints, and any potential contract options that may or may not be awarded in the future, and are at the sole discretion of award by the customer. Past performance is not necessarily an indicator of future results. Considering these and other uncertainties, the inclusion of forward-looking statements in this press release should not be regarded as a representation by the Company that the Company's plans, estimates, forecasts, goals, intentions, or objectives will be achieved or realized. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. The Company assumes no obligation to update information contained in this press release whether as a result of new developments or otherwise, except as required by law.

Please refer to the Company's 2025 Annual Report on Form 10-K, filed on March 4, 2026 which is available on its website at www.oriongroupholdingsinc.com or at the SEC's website at www.sec.gov, and filings and press releases subsequent to such Annual Report on Form 10-K for additional and more detailed discussion of risk factors that could cause actual results to differ materially from our current expectations, estimates or forecasts.

2 DISCLAIMER 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; and our expected margin growth; our pipeline of opportunity; the expected benefits, results, growth and integration of our acquisition of J.E. McAmis; 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.
