Item 2.02 Results of Operations and Financial Condition.

On October 28, 2025, Orion Group Holdings, Inc. (the “Company”) issued a press release announcing its financial results for the third quarter ended September 30, 2025. 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 October 29, 2025, the Company posted the third quarter 2025 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.

Contract revenues were $225.1 million in the third quarter of 2025 compared with $226.7 million in the third quarter last year and up 10% sequentially from $205.3 million in the second quarter of 2025, driven by increased volume in our Marine and Concrete segments.

Gross profit was $29.8 million, up 10% from $27.1 million in the third quarter of 2024 and up 16% from $25.8 million in the second quarter of 2025. The increases in gross profit were driven by strong project execution primarily in our Marine business.

Selling, general and administrative (“SG&A”) expenses were $25.1 million for the quarter, up from $20.8 million in the third quarter of 2024 primarily due to increased investment to support business growth.

GAAP net income for the third quarter was $3.3 million, or $0.08 per diluted share, compared to net income of $4.3 million, or $0.12 per diluted share, in the third quarter of 2024.

Adjusted EBITDA for the third quarter was $13.1 million, compared to $15.2 million in the third quarter of 2024 and up 19% from $11.0 million in the second quarter of 2025. The year-over-year decrease is primarily attributable to favorable project close outs in 2024 that did not reoccur in 2025. The sequential increase was driven by revenue growth and strong execution.

Balance Sheet Update

As of September 30, 2025, current assets were $269.7 million, including unrestricted cash and cash equivalents of $4.9 million. Total debt outstanding as of September 30, 2025 was $23.6 million and the Company had no borrowings under its revolving credit facility.

Recent Developments

In September 2025, the Company announced the appointment of Robert Ledford to its Board of Directors, effective November 19, 2025. Mr. Ledford’s decades of experience leading complex global businesses in the construction industry and driving strategic growth through mergers and acquisitions will provide valuable insight for our Board and executive team as Orion executes its growth strategy.

In October 2025, the Company increased its aggregate bonding capacity by $400 million, which enables the Company to bid on and capture larger projects to accelerate Orion’s long-term growth.  

In October 2025, the Company closed on the sale of its East and West Jones property for an aggregate purchase price of $23.5 million. Proceeds are expected to be used to reduce debt and for general corporate purposes.  In connection with the sale of the property, the Company entered into an Exclusive Dredge Spoils Agreement with the purchaser. Under the Agreement, the Company has the right to deliver dredge spoils to the property for ten years, which is expected to decrease the Company’s disposal costs.

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 projects ranges from three to nine months on shorter projects to multiple years on larger projects. 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 “non-GAAP financial measures” under rules of the 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.

3


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 Group Holdings 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. 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, 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 which 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.

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, 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. 2
