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.

See definitions and reconciliation of non-GAAP measures elsewhere in this release.

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.

Backlog Definition

Backlog consists of projects under contract that have either (a) not been started, or (b) are in progress but are not yet complete. The Company cannot guarantee that the revenue implied by its backlog will be realized, or, if realized, will result in earnings or profitability. Backlog can fluctuate from period to period due to the timing and execution of contracts. The typical duration of the Company’s Concrete projects ranges from six to twelve months and Marine projects range from 18 to 24 months. The Company's backlog at any point in time includes both revenue it expects to realize during the next twelve-month period as well as revenue it expects to realize in future years.

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
