1.Description of Business and Basis of Presentation

Description of Business

Orion Group Holdings, Inc. and its subsidiaries (hereafter collectively referred to as the “Company”), is a leading specialty construction company serving the infrastructure, industrial, and building sectors, providing services both on and off the water in the continental United States, Alaska, Hawaii, Canada and the Caribbean Basin through our marine and concrete segments. We are headquartered in Houston, Texas with regional offices throughout our operating areas.

Basis of Presentation

The accompanying condensed consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Accordingly, these financial statements do not include certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and should be read together with our 2024 Annual Report on Form 10-K. For the periods presented, there were no items of other comprehensive income.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows for the periods presented. Such adjustments are of a normal recurring nature. Interim results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results realizable for the year ending December 31, 2025.

2.Recent Accounting Pronouncements

The Financial Accounting Standards Board (“FASB”) issues accounting standards and updates (each, an “ASU”) from time to time to its Accounting Standards Codification (“ASC”), which is the primary source of U.S. GAAP. The Company regularly monitors ASUs as they are issued and considers applicability to its business. All ASUs are adopted by their respective due dates and in the manner prescribed by the FASB.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments require disclosure of specific categories in the rate reconciliation and provides additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. This will not impact our financial position or results of operations, but is expected to result in expanded tax disclosures in the full year financial statements for the year ended December 31, 2025.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The amendments require entities to provide enhanced disaggregation of certain expense categories presented in the income statement, including details on significant

Table of Contents

components within those categories, to provide greater transparency and decision-useful information to users of financial statements. The ASU is effective for fiscal years beginning after December 15, 2026, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures within its consolidated financial statements.

3.Revenue

Contract revenues are recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The following table represents a disaggregation of the Company’s contract revenues by service line for the marine and concrete segments:


	Three Months Ended June 30,				Six Months Ended June 30,
	2025		2024		2025		2024
Marine Segment
Construction	$	114,830	$	116,025	$	219,312	$	204,814
Dredging		17,700		12,077		34,611		26,747
Specialty services		2,772		2,851		8,542		5,717
Marine segment contract revenues	$	135,302	$	130,953	$	262,465	$	237,278

Concrete Segment
Structural	$	12,582	$	16,895	$	26,303	$	28,468
Light commercial		57,402		44,319		105,171		87,093
Concrete segment contract revenues	$	69,984	$	61,214	$	131,474	$	115,561

Total contract revenues	$	205,286	$	192,167	$	393,939	$	352,839

The Company has determined that it has two reportable segments as described in Note 15, but has disaggregated its contract revenues in the above chart in terms of services provided within such segments. Additionally, both the marine and concrete segments have limited contracts with multiple performance obligations. The Company’s contracts are often estimated and bid as one project and performance is evaluated as one project, not by individual services performed by each.

Additionally, the table below represents contract revenue by type of customer for the three and six months ended June 30, 2025 and 2024, respectively:


	Three Months Ended June 30,								Six Months Ended June 30,
	2025		%		2024		%		2025		%		2024		%
Federal Government	$	39,429	19	%	$	67,021	35	%	$	81,313	21	%	$	120,403	34	%
State Governments		36,322	18	%		15,453	8	%		65,283	17	%		29,437	8	%
Local Government		43,127	21	%		26,892	14	%		80,164	20	%		55,865	16	%
Private Companies		86,408	42	%		82,801	43	%		167,179	42	%		147,134	42	%
Total contract revenues	$	205,286	100	%	$	192,167	100	%	$	393,939	100	%	$	352,839	100	%

On March 10, 2023, the United States Navy awarded the Dragados/Hawaiian Dredging/Orion Joint Venture a contract to complete the construction of a dry dock at Pearl Harbor Naval Shipyard. The Company’s joint venture with Dragados/Hawaiian Dredging is a related-party transaction. The Company’s portion of work as a dedicated subcontractor totals $458.7 million.

Table of Contents

For the three months ended June 30, 2025 and 2024, the United States Navy, included in the Federal Government category, accounted for 16.4% and 28.9% of total contract revenues, respectively. For the six months ended June 30, 2025 and 2024, the United States Navy, included in the Federal Government category, accounted for 16.9% and 26.5% of total contract revenues, respectively.

For the three months ended June 30, 2025 and 2024, the Company’s revenue related to the joint venture subcontract was approximately $33.3 million and $55.5 million, respectively. For the six months ended June 30, 2025 and 2024, the Company’s revenue related to the joint venture subcontract was approximately $66.6 million and $93.5 million, respectively.

The Company does not believe that the loss of any one of its customers would have a material adverse effect on the Company or its subsidiaries and affiliates since no single specific customer sustains such a large portion of receivables or contract revenue over time.

Contract revenues generated outside the United States totaled 5.6% and 8.6% of total revenues for the three months ended June 30, 2025 and 2024, respectively, and 5.9% and 7.4% for the six months ended June 30, 2025 and 2024, respectively, and were primarily located in the Caribbean Basin.

4.Concentration of Risk and Enterprise-Wide Disclosures

Accounts receivable include amounts billed to governmental agencies and private customers and do not bear interest. Balances billed to customers but not paid pursuant to retainage provisions generally become payable upon contract completion and acceptance by the owner.

The table below presents the concentrations of current receivables (trade and retainage) at June 30, 2025 and December 31, 2024, respectively:


	June 30, 2025				December 31, 2024
Federal Government	$	56,499	26	%	$	19,874	14	%
State Governments		19,692	9	%		9,553	7	%
Local Governments		36,760	17	%		24,641	17	%
Private Companies		100,618	48	%		88,424	62	%
Gross receivables		213,569	100	%		142,492	100	%
Allowance for credit losses		(1,099)				(555)
Net receivables	$	212,470			$	141,937

At June 30, 2025, the United States Navy, which is included in the Federal Government category, accounted for 25.8% of total current receivables. At December 31, 2024, the United States Navy, accounted for 11.1% of total current receivables.

7.Fair Value

Recurring Fair Value Measurements

The fair value of financial instruments is the amount at which the instrument could be exchanged in a current transaction between willing parties. Due to their short-term nature, the Company believes that the carrying value of its accounts receivable, other current assets, accounts payable and other current liabilities approximate their fair values.

The Company classifies financial assets and liabilities into the following three levels based on the inputs used to measure fair value in the order of priority indicated:

●

Level 1- fair values are based on observable inputs such as quoted prices in active markets for identical assets or liabilities;

●

Level 2 - fair values are based on pricing inputs other than quoted prices in active markets for identical assets and liabilities and are either directly or indirectly observable as of the measurement date; and

●

Level 3 - fair values are based on unobservable inputs in which little or no market data exists.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value requires judgment and may affect the placement of assets and liabilities within the fair value hierarchy levels.

Our concrete segment has life insurance policies with a combined face value of $11.1 million as of June 30, 2025. These policies are invested in mutual funds and the fair value measurement of the cash surrender balance associated with these policies is determined using Level 2 inputs within the fair value hierarchy and will vary with investment performance. The fair value of the cash surrender value of these policies at June 30, 2025 and December 31, 2024 was $1.3 million and $1.2 million, respectively. These assets are included in the "Other non-current" asset section in the Company’s Condensed Consolidated Balance Sheets.

Other Fair Value Measurements

The fair value of the Company’s debt at June 30, 2025 and December 31, 2024 approximated its carrying value of $36.6 million and $26.8 million, respectively, as interest is based on current market interest rates for debt with similar risk and maturity.

(1)	Total debt issuance costs include underwriter fees, legal fees, syndication fees and fees related to the execution of the Credit Agreement and the termination and repayment of the Company’s prior credit facility.

On May 15, 2023, the Company entered into a Credit Agreement (the “Credit Agreement”) with White Oak ABL, LLC and White Oak Commercial Finance, LLC, providing for a $65.0 million asset-based revolving credit facility (the “Revolver”) and a $38.0 million fixed asset term loan (the “Term Loan”). The Credit Agreement, as subsequently amended, matures on May 15, 2028 and is secured by substantially all of the assets of the Company and its subsidiaries, including fixed assets and accounts receivable.

The Company has a maximum borrowing capacity under the Revolver of $65.0 million. There is a letter of credit sublimit that is equal to the lesser of $5.0 million and the aggregate unused amount of the revolving commitments then in effect.

The Company is subject to a commitment fee for the unused portion of the maximum borrowing availability under the Revolver. The Revolver termination date is the earlier of the Credit Agreement termination date, May 15, 2028, or the date the outstanding balance is permanently reduced to zero, in accordance with the terms of the Credit Agreement.

As of June 30, 2025, the Company had $10.0 million in borrowings under the Revolver. The Company’s borrowing availability under the Revolver at June 30, 2025 was approximately $21.9 million.

Table of Contents

The Credit Agreement is used to finance working capital and general corporate purposes, capital expenditures, permitted acquisitions and associated transaction fees, and to refinance existing indebtedness. Borrowings under the Revolver may be repaid and reborrowed, subject to the borrowing base and other conditions.

As amended, the Revolver and Term Loan bear interest at rates based on 30-day SOFR plus applicable margins, subject to a SOFR floor. As of June 30, 2025, the applicable margin is 4.25% for the Revolver and 6.50% for the Term Loan, with a 4.00% SOFR floor.

The quarterly weighted average interest rate for the Credit Agreement, as of June 30, 2025 and 2024 was 10.46% and 12.07%, respectively.

The Credit Agreement contains customary affirmative and negative covenants, including limitations on indebtedness, liens, investments, asset sales, and dividends, as well as financial maintenance covenants. The financial covenants, as amended, include a minimum Consolidated Fixed Charge Coverage Ratio and/or Consolidated EBITDA thresholds and a minimum liquidity requirement, each tested periodically.

Financial covenants

Restrictive financial covenants under the amended Credit Agreement include:

●

A Consolidated Fixed Charge Coverage Ratio to not be less than the following during each noted period:

Sale-Leaseback Arrangements

On May 15, 2023, the Company entered into a $13.0 million sale-leaseback of certain equipment pursuant to which the Company leased-back the equipment for terms ranging from one to three years. The transaction above was recorded as a failed sale-leaseback.

Concurrent with the sale of Company’s Port Lavaca South Yard property, the Company entered into a twenty-year lease agreement whereby the Company leased back the property at an annual rental rate of approximately $1.1 million, subject to annual rent increases of 2.5%. Under the lease agreement, the Company has four consecutive options to extend the term of the lease by five years for each such option. The portion of the above transaction related to the building was recorded as a failed sale-leaseback.

On September 27, 2019, the Company entered into a purchase and sale agreement (the “Purchase and Sale Agreement”). Pursuant to the terms of the Purchase and Sale Agreement, the Company sold its 17300 and 17140 Market Street location in Channelview, Texas for a purchase price of $19.1 million. Concurrent with the sale of the property, the Company entered into a fifteen-year lease agreement whereby the Company leased back the property at an annual rental rate of approximately $1.5 million, subject to annual rent increases of 2.0%. Under the lease agreement, the Company has two consecutive options to extend the term of the lease by ten years for each such option. The transaction above was recorded as a failed sale-leaseback.

Related to the failed sale-leasebacks, the Company recorded liabilities for the amounts received, will continue to depreciate the non-land portion of the assets, and has imputed an interest rate so that the net carrying amount of the financial liability and remaining assets will be zero at the end of the initial lease terms.

11.Income Taxes

The Company’s effective tax rate is based on expected income, statutory rates and tax planning opportunities available to it. For interim financial reporting, the Company estimates its annual tax rate based on projected taxable income for the full year and records a quarterly tax provision in accordance with the anticipated annual rate.

Income tax (benefit) expense included in the Company’s accompanying Condensed Consolidated Statements of Operations was as follows:


	Three Months Ended						Six Months Ended
	June 30,						June 30,
		2025			2024			2025			2024
Income tax (benefit) expense	$	(212)		$	617		$	(72)		$	265
Effective tax rate		(33.7)	%		(10.3)	%		11.2	%		(2.1)	%

The effective rate for the three and six months ended June 30, 2025 differed from the Company’s statutory federal rate of 21% primarily due to the tax impact from the valuation allowance for current year activity, state income taxes and the non-deductibility of other permanent items.

The Company assessed the realizability of its deferred tax assets and determined that it was more likely than not that some portion or all the deferred tax assets would not be realized and therefore recorded a valuation allowance on the net deferred tax assets. The Company assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. The Company considers the scheduled reversal of deferred tax liabilities, available carryback periods, and tax-planning strategies in making this assessment. For the three and six months ended June 30, 2025 the Company evaluated positive and negative evidence in determining the amount of deferred tax assets more likely than not to be realized. Based on the review of available evidence, management believes that a valuation allowance on the net deferred tax assets at June 30, 2025 remains appropriate.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes provisions, that may impact our tax rate such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The Company is currently assessing the potential impact on its consolidated financial statements.

12.Earnings Per Share

Basic earnings per share is based on the weighted average number of common shares outstanding during each period. Diluted earnings per share is based on the weighted average number of common shares outstanding as well as the effect of all dilutive common stock equivalents during each period net income is generated. For the three months ended June 30, 2025 and 2024, the Company had 48,940 and 181,025 shares, respectively, that were potentially dilutive in earnings per share calculations. For the six months ended June 30, 2025 and 2024, the Company had 52,103 and 201,550 shares, respectively, that were potentially dilutive in earnings per share calculations. Such dilution is dependent on the excess of the market price of our stock over the exercise price and other components of the treasury stock method. The exercise price for certain stock options awarded by the Company exceeded the average market price of the Company’s common stock for the three and six months ended June 30, 2025 and 2024. Such stock options are antidilutive and are not included in the computation of earnings per share for those periods. The Company reported a net loss for the three months

Table of Contents

ended June 30, 2024 and the six months ended June 30, 2025 and 2024; therefore, all potentially dilutive securities are antidilutive and are excluded from the computation of diluted loss per share for such periods.

The following table reconciles the denominators used in the computations of both basic and diluted earnings per share:


	Three Months Ended June 30,		Six Months Ended June 30,
	2025	2024	2025	2024

13.Share-Based Compensation

The Compensation Committee of the Company’s Board of Directors is responsible for the administration of the Company’s stock incentive plans. In general, the Company’s 2022 LTIP provides for grants of restricted stock and performance-based awards to be issued with a per-share price not less than the fair market value of a share of common stock on the date of grant. The Company accounts for forfeitures of awards as they are incurred.

In May 2024 shareholders approved the ESPP, which became effective on September 16, 2024. The Company has reserved a total of 1,000,000 shares under the ESPP, all of which are authorized and available for future issuance under the ESPP. During the six months ended June 30, 2025, there were 71,133 shares issued under the ESPP generating proceeds to the Company of $0.3 million. The Company has an outstanding liability pertaining to the ESPP of $0.3 million as of June 30, 2025, included in accrued expenses, for employee contributions to the ESPP, pending issuance at the end of the offering period.

The table below presents the share-based compensation expense included in the Company’s accompanying condensed consolidated statements of operations:


	Three Months Ended June 30,				Six Months Ended June 30,

A maximum of 1.2 million common shares could be awarded based upon the Company’s achievement of set performance-metrics.

On March 20, 2025, the Company granted certain executives a total of 293,073 performance-based units. The performance-based units will potentially vest 100% if the target is met, with 50% of the units to be earned based on the achievement of an absolute adjusted EBITDA target, measured in the final year of a three-year performance period and 50% of the units to be earned based on the achievement of an objective, tiered return on relative total shareholder return, measured over a three-year performance period. The Company evaluates the probability of achieving targeted award levels each reporting period. The fair value of the grants awarded related to the adjusted EBITDA target was $5.89 per share and the fair value of the grants awarded related to the relative total shareholder return target was $8.45 valued using a Monte Carlo simulation model.

The following table presents the assumptions related to the performance share units granted in 2025 related to the relative total shareholder return, as indicated in the previous summary table:


		2025
Grant-date fair value	$	5.89
Risk-free interest rate		3.86	%
Volatility factor		65.52	%
Contractual term (years)		2.78

14.Commitments and Contingencies

The Company is involved in various legal and other proceedings that are incidental to the conduct of its business, none of which in the opinion of management will have a material effect on the Company’s financial condition, results of operations or cash flows. Management believes that it has recorded adequate accrued liabilities and believes that it has adequate insurance coverage or has meritorious defenses for these claims and contingencies.

15.Segment Information

The Company has determined that it has two reportable segments pursuant to ASC Topic 280, Segment Reporting. The tools used by the chief operating decision maker (“CODM”) to allocate resources and assess performance are based on two reportable and operating segments: marine and concrete, which operate under the Orion brand and logo.

In making this determination, the Company considered the similar economic characteristics of each segment’s operations, including internal processes, customer base, regulatory oversight, and macroeconomic factors that drive each. Both the marine and concrete segments have a single individual responsible for managing the entire segment. Resources are allocated by segment and financial and budgetary information is compiled and reviewed by segment.

Marine Segment

Our marine segment provides construction, dredging and specialty services. Construction services include construction, restoration, maintenance, dredging and repair of marine transportation facilities, marine pipelines, bridges and causeways and marine environmental structures. Dredging services generally enhance or preserve the navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. Specialty services include design, salvage, demolition, surveying, towing, diving and underwater inspection, excavation and repair.

Concrete Segment

Our concrete segment provides turnkey concrete construction services, including concrete surface place and finish, site preparation, layout, forming, and rebar placement for large commercial, structural and other associated business areas.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

Unless the context otherwise indicates, all references in this Quarterly Report on Form 10-Q to “Orion,” “the Company,” “we,” “our,” or “us” are to Orion Group Holdings, Inc. and its subsidiaries as a whole.

Certain information in this Quarterly Report on Form 10-Q, including but not limited to Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), may constitute forward-looking statements as such term is defined 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.

All statements other than statements of historical facts, including those that express a belief, expectation, or intention are forward-looking statements. The forward-looking statements may include projections and estimates concerning the timing and success of specific projects and our future production, our pipeline of opportunities, conversion of backlog, revenues, income and capital spending. Our forward-looking statements are generally accompanied by words such as “estimate,” “project,” “predict,” “believe,” “expect,” “anticipate,” “potential,” “plan,” “goal” or other words that convey the uncertainty of future events or outcomes.

We have based these forward-looking statements on our current expectations and assumptions about future events. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control, including unforeseen productivity delays and other difficulties encountered in project execution, challenges incurred by virtue of our position as a substantial subcontractor that reports to a significantly larger project contractor, levels of government funding or other governmental budgetary constraints, contract modifications and changes, including change orders and contract cancellation at the discretion of the customer, and the general economic impact of tariffs and trade wars. These and other important factors, including those described under “Risk Factors” in Part 1, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024 may cause our actual results, performance- or achievements to differ materially from any future results, performance or achievements expressed or implied by these forward-looking statements. The forward-looking statements in this Quarterly Report on Form 10-Q speak only as of the date of this report; we disclaim any obligation to update these statements unless required by securities law, and we caution you not to rely on them unduly.

MD&A provides a narrative analysis explaining the reasons for material changes in the Company’s (i) financial condition since the most recent fiscal year-end, and (ii) results of operations during the current fiscal year-to-date period and current fiscal quarter as compared to the corresponding periods of the preceding fiscal year. In order to better understand such changes, this MD&A should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in our 2024 Form 10-K, Part II, Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our 2024 Form 10-K and with our unaudited condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q.

Overview

Table of Contents

services both on and off the water in the continental United States, Alaska, Hawaii, Canada and the Caribbean Basin through our marine segment and our concrete segment.

Our contracts are obtained primarily through competitive bidding in response to “requests for proposals” by federal, state and local agencies and through negotiation and competitive bidding with private parties and general contractors. Our bidding activity and strategies are affected by factors such as our backlog, current utilization of equipment and other resources, job location, our ability to obtain necessary surety bonds and competitive considerations. The timing and location of awarded contracts may result in unpredictable fluctuations in the results of our operations.

Most of our revenue is derived from fixed-price contracts. We record revenue on construction contracts over time, measured by the percentage of actual contract costs incurred to date to total estimated costs for each contract. There are a number of factors that can create variability in contract performance and therefore impact the results of our operations. The most significant of these include the following:

●

completeness and accuracy of the original bid;

●

increases in commodity prices such as concrete, steel and fuel;

●

customer delays, work stoppages, and other costs due to weather and environmental restrictions;

●

subcontractor performance;

●

unforeseen site conditions;

●

availability and skill level of workers; and

●

a change in availability and proximity of equipment and materials.

All of these factors can have a negative impact on our contract performance, which can adversely affect the timing of revenue recognition and ultimate contract profitability. We plan our operations and bidding activity with these factors in mind and they generally have not had a material adverse impact on the results of our operations in the past.

Consolidated Results of Operations

Backlog Information

Our contract backlog represents our estimate of the revenues we expect to realize under the portion of contracts remaining to be performed. Given the typical duration of our contracts, which is generally less than a year, our

Table of Contents

backlog at any point in time usually represents only a portion of the revenue that we expect to realize during a twelve-month period. We have not been adversely affected by contract cancellations or modifications in the past, however we may be in the future, especially in periods of economic uncertainty.

Backlog as of the periods ended below are as follows (in millions):


	June 30, 2025		December 31, 2024
Marine segment	$	554.8	$	582.8
Concrete segment		190.9		146.3
Consolidated	$	745.7	$	729.1

Backlog is not necessarily indicative of future results. In addition to our backlog under contract, we also have a substantial number of projects in negotiation or pending award at any given time.

Contract Revenues. Contract revenues for the three months ended June 30, 2025 of $205.3 million increased $13.1 million, or 6.8%, as compared to $192.2 million in the prior year period. The increase was primarily due to new awards and higher volume across the marine and concrete segments.

Gross Profit. Gross profit was $25.8 million for the three months ended June 30, 2025 compared to $18.3 million in the prior year period, an increase of $7.5 million, or 41.1%. The increase in gross profit was primarily driven by increased revenue, improvement in marine projects, and reduced indirect expenses, partially offset by favorable concrete project close-outs in 2024 that did not reoccur in 2025.

Selling, General and Administrative Expense. Selling, general and administrative (“SG&A”) expenses were $22.8 million for the three months ended June 30, 2025 compared to $21.1 million in the prior year period, an increase of $1.7 million or 7.8%. The increase in SG&A was primarily due to increased spending to support business growth.

Table of Contents

Gain on Disposal of Assets, net. During the three months ended June 30, 2025 and 2024 we realized $0.4 million and $0.1 million, respectively, of net gains on disposal of assets.

Other Income, net of Expense. Other expense primarily reflects interest on our borrowings, partially offset by interest income and non-operating gains or losses.

Income Tax (Benefit) Expense. We recorded a tax benefit of $0.2 million in the three months ended June 30, 2025, compared to a tax expense of $0.6 million in the prior year period. Our effective tax rate for the three months ended June 30, 2025 differs from the federal statutory rate primarily due to the tax impact from the valuation allowance for current year activity, state income taxes and the non-deductibility of other permanent items.

Contract Revenues. Contract revenues for the six months ended June 30, 2025 of $393.9 million increased $41.1 million or 11.6% as compared to $352.8 million in the prior year period. The increase was primarily due to new awards and higher volume across the marine and concrete segments.

Gross Profit. Gross profit was $48.8 million for the six months ended June 30, 2025 compared to $33.8 million in the prior year period, an increase of $15.0 million, or 44.3%. The increase in gross profit was primarily driven by increased revenue, improvement in marine projects, and reduced indirect expenses, partially offset by favorable concrete project close-outs in 2024 that did not reoccur in 2025.

Selling, General and Administrative Expense. SG&A expenses were $45.3 million for the six months ended June 30, 2025 compared to $40.1 million in the prior year period, an increase of $5.2 million, or 12.9%. The increase in SG&A was primarily due to increased spending to support business growth.

Concrete Segment

Revenues for our concrete segment for the three months ended June 30, 2025 were $70.0 million compared to $61.2 million for the three months ended June 30, 2024, an increase of $8.8 million, or 14.3%. This increase was primarily due to new awards and higher volume on our concrete contracts.

Operating loss for our concrete segment for the three months ended June 30, 2025 was $2.8 million, compared to operating income of $2.7 million for the three months ended March 31, 2024, a decrease of $5.5 million. This decrease was primarily driven by favorable concrete project close-outs in 2024 that did not reoccur in 2025.

Marine Segment

Revenues for our marine segment for the six months ended June 30, 2025 were $262.5 million compared to $237.3 million for the six months ended June 30, 2024, an increase of $25.2 million, or 10.6%. The increase was primarily due to new awards and higher volume on our marine construction contracts.

Operating income for our marine segment for the six months ended June 30, 2025 was $11.0 million, compared to an operating loss of $10.3 million for the six months ended June 30, 2024, an increase of $21.3 million. The increase in gross profit was primarily driven by increased revenue, reduced indirect expenses, and project delays in 2024 that did not reoccur in 2025.

Concrete Segment

Revenues for our concrete segment for the six months ended June 30, 2025 were $131.5 million compared to $115.6 million for the six months ended June 30, 2024, an increase of $15.9 million, or 13.8%. This increase was primarily due to new awards and higher volume on our concrete contracts.

Table of Contents

Operating loss for our concrete segment for the six months ended June 30, 2025 was $6.7 million, compared to operating income of $4.4 million for the six months ended June 30, 2024, a decrease of $11.1 million. This decrease was primarily driven by favorable concrete project close-outs in 2024 that did not reoccur in 2025.

Liquidity and Capital Resources

Changes in working capital are normal within our business given the varying mix in size, scope, seasonality and timing of delivery of our projects. At June 30, 2025, our working capital was $76.9 million, as compared to $78.2 million at December 31, 2024. As of June 30, 2025, we had unrestricted cash on hand of $1.7 million. Our borrowing availability under the revolving portion of our Credit Agreement at June 30, 2025 was approximately $21.9 million.

Our primary liquidity needs are to finance our working capital and fund capital expenditures. Historically, our sources of liquidity have been cash provided by our operating activities, sale of underutilized assets, borrowings under our credit facilities, and equity issuances. The assessment of our liquidity requires us to make estimates of future activity and judgments about whether we are compliant with financial covenant calculations under our debt and other agreements and have adequate liquidity to operate. Significant assumptions used in our forecasted model of liquidity include forecasted sales, costs, and capital expenditures, as well as expected timing and proceeds of planned asset sale transactions. As of June 30, 2025, management believes the Company will have adequate liquidity for its operations for at least the next 12 months.

Cash Flow

The following table provides information regarding our cash flows and our capital expenditures for the three and six months ended June 30, 2025 and 2024:


	Six months ended

Cash flows (used in) provided by financing activities	$	(2,603)	$	18,189

Capital expenditures (included in investing activities above)	$	(16,165)	$	(6,487)

Operating Activities. During the six months ended June 30, 2025 we used approximately $9.0 million of cash in our operating activities. The net cash outflow was comprised of $26.9 million of outflows related to changes in net working capital, partially offset by $17.9 million of cash inflows from net income, after adjusting for non-cash items. The changes in net working capital, which are reflected as changes in operating assets and liabilities in our Condensed Consolidated Statements of Cash Flows, were primarily driven by a $58.8 million cash outflow related to a decrease in our net position of accounts receivable and accounts payable plus accrued liabilities during the period and a $3.2 million decrease in operating lease liabilities, partially offset by $34.8 million of cash inflows pursuant to the relative timing and significance of project progression and billings during the period.

Table of Contents

Investing Activities. During the six months ended June 30, 2025, we used approximately $15.0 million of cash in our investing activities. Capital asset additions and betterments to our fleet were $16.2 million and $6.5 million in the six months ended June 30, 2025 and 2024, respectively.

Financing Activities. During the six months ended June 30, 2025, we used approximately $2.6 million of cash in our financing activities. During the six months ended June 30, 2025, we had borrowings on credit of $77.0 million and repayments of $67.0 million on the White Oak revolving credit line, payments on finance lease liabilities of $5.3 million, payments made on failed sale-leaseback arrangements of $7.2 million.

Sources of Capital

On May 15, 2023, we entered into a new three-year $103.0 million Credit Agreement with White Oak, which includes a $65.0 million asset based revolving credit line and a $38.0 million fixed asset term loan. Please see “Note 9 – Debt” in our unaudited condensed consolidated financial statements for a more detailed description of the Credit Facility.

We were in compliance with all financial covenants under the amended agreement as of June 30, 2025.

Bonding Capacity

We are often required to provide various types of surety bonds that provide additional security to our customers for our performance under certain government and private sector contracts. Our ability to obtain surety bonds depends on our capitalization, working capital, past performance and external factors, including the capacity of the overall surety market. At June 30, 2025, the capacity under our current bonding arrangement was $1.1 billion, with approximately $485 million of projects being bonded. While we believe that our current bonding capacity is sufficient to satisfy current demand for our services, any new major project opportunities may require us to seek additional bonding capacity in the future. We believe our balance sheet and working capital position will allow us to access additional bonding capacity as needed in the future.

Effect of Inflation

We are subject to the effects of inflation through increases in the cost of raw materials, and other items such as fuel, concrete and steel. Due to the relative short-term duration of our projects, we are generally able to include anticipated cost increases in the pricing of our bids.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, our results of operations are subject to risks related to fluctuations in commodity prices and fluctuations in interest rates. Historically, our exposure to foreign currency fluctuations has not been material and has been limited to temporary field accounts located in foreign countries where we perform work. Foreign currency fluctuations were immaterial in this reporting period.

Commodity price risk

We are subject to fluctuations in commodity prices for concrete, steel products and fuel. Although we routinely attempt to secure firm quotes from our suppliers, we generally do not hedge against increases in prices for commodity products. Commodity price risks may have an impact on our results of operations due to the fixed-price nature of many of our contracts, although the short-term duration of our projects may allow us to include cost increases to the pricing of our bids.

Table of Contents

Interest rate risk

At June 30, 2025, we had $33.0 million in outstanding borrowings under our Credit Agreement, with a weighted average ending interest rate of 10.25%. Based on the amounts outstanding under our Credit Agreement as of June 30, 2025, a 100 basis-point increase in SOFR (or an equivalent successor rate) would increase the Company’s annual interest expense by approximately $0.3 million.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As required, the Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, have conducted an evaluation of the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2025.

Changes in Internal Control over Financial Reporting

During the quarter ended June 30, 2025, we implemented new reporting systems and made changes to related internal controls. There have been no other changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of Business and Basis of Presentation
1.Description of Business and Basis of Presentation
Description of Business
Orion Group Holdings, Inc. and its subsidiaries (hereafter collectively referred to as the “Company”), is a leading specialty construction company serving the infrastructure, industrial, and building sectors, providing services both on and off the water in the continental United States, Alaska, Hawaii, Canada and the Caribbean Basin through our marine and concrete segments. We are headquartered in Houston, Texas with regional offices throughout our operating areas.
Basis of Presentation
The accompanying condensed consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Accordingly, these financial statements do not include certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and should be read together with our 2024 Annual Report on Form 10-K. For the periods presented, there were no items of other comprehensive income.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows for the periods presented. Such adjustments are of a normal recurring nature. Interim results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results realizable for the year ending December 31, 2025.

Summary of Significant Accounting Principles
2.Recent Accounting Pronouncements
The Financial Accounting Standards Board (“FASB”) issues accounting standards and updates (each, an “ASU”) from time to time to its Accounting Standards Codification (“ASC”), which is the primary source of U.S. GAAP. The Company regularly monitors ASUs as they are issued and considers applicability to its business. All ASUs are adopted by their respective due dates and in the manner prescribed by the FASB.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments require disclosure of specific categories in the rate reconciliation and provides additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. This will not impact our financial position or results of operations, but is expected to result in expanded tax disclosures in the full year financial statements for the year ended December 31, 2025.
In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The amendments require entities to provide enhanced disaggregation of certain expense categories presented in the income statement, including details on significant
components within those categories, to provide greater transparency and decision-useful information to users of financial statements. The ASU is effective for fiscal years beginning after December 15, 2026, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures within its consolidated financial statements.

The Company has determined that it has two reportable segments as described in Note 15, but has disaggregated its contract revenues in the above chart in terms of services provided within such segments. Additionally, both the marine and concrete segments have limited contracts with multiple performance obligations. The Company’s contracts are often estimated and bid as one project and performance is evaluated as one project, not by individual services performed by each.
Additionally, the table below represents contract revenue by type of customer for the three and six months ended June 30, 2025 and 2024, respectively:

On March 10, 2023, the United States Navy awarded the Dragados/Hawaiian Dredging/Orion Joint Venture a contract to complete the construction of a dry dock at Pearl Harbor Naval Shipyard. The Company’s joint venture with Dragados/Hawaiian Dredging is a related-party transaction. The Company’s portion of work as a dedicated subcontractor totals $458.7 million.
For the three months ended June 30, 2025 and 2024, the United States Navy, included in the Federal Government category, accounted for 16.4% and 28.9% of total contract revenues, respectively. For the six months ended June 30, 2025 and 2024, the United States Navy, included in the Federal Government category, accounted for 16.9% and 26.5% of total contract revenues, respectively.
For the three months ended June 30, 2025 and 2024, the Company’s revenue related to the joint venture subcontract was approximately $33.3 million and $55.5 million, respectively. For the six months ended June 30, 2025 and 2024, the Company’s revenue related to the joint venture subcontract was approximately $66.6 million and $93.5 million, respectively.
The Company does not believe that the loss of any one of its customers would have a material adverse effect on the Company or its subsidiaries and affiliates since no single specific customer sustains such a large portion of receivables or contract revenue over time.
Contract revenues generated outside the United States totaled 5.6% and 8.6% of total revenues for the three months ended June 30, 2025 and 2024, respectively, and 5.9% and 7.4% for the six months ended June 30, 2025 and 2024, respectively, and were primarily located in the Caribbean Basin.

Fair Value Disclosures [Abstract]

Fair Value
7.Fair Value
Recurring Fair Value Measurements
The fair value of financial instruments is the amount at which the instrument could be exchanged in a current transaction between willing parties. Due to their short-term nature, the Company believes that the carrying value of its accounts receivable, other current assets, accounts payable and other current liabilities approximate their fair values.
The Company classifies financial assets and liabilities into the following three levels based on the inputs used to measure fair value in the order of priority indicated:
● Level 1- fair values are based on observable inputs such as quoted prices in active markets for identical assets or liabilities;
● Level 2 - fair values are based on pricing inputs other than quoted prices in active markets for identical assets and liabilities and are either directly or indirectly observable as of the measurement date; and
● Level 3 - fair values are based on unobservable inputs in which little or no market data exists.
Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value requires judgment and may affect the placement of assets and liabilities within the fair value hierarchy levels.
Our concrete segment has life insurance policies with a combined face value of $11.1 million as of June 30, 2025. These policies are invested in mutual funds and the fair value measurement of the cash surrender balance associated with these policies is determined using Level 2 inputs within the fair value hierarchy and will vary with investment performance. The fair value of the cash surrender value of these policies at June 30, 2025 and December 31, 2024 was $1.3 million and $1.2 million, respectively. These assets are included in the "Other non-current" asset section in the Company’s Condensed Consolidated Balance Sheets.
Other Fair Value Measurements
The fair value of the Company’s debt at June 30, 2025 and December 31, 2024 approximated its carrying value of $36.6 million and $26.8 million, respectively, as interest is based on current market interest rates for debt with similar risk and maturity.

(1) Total debt issuance costs include underwriter fees, legal fees, syndication fees and fees related to the execution of the Credit Agreement and the termination and repayment of the Company’s prior credit facility.
On May 15, 2023, the Company entered into a Credit Agreement (the “Credit Agreement”) with White Oak ABL, LLC and White Oak Commercial Finance, LLC, providing for a $65.0 million asset-based revolving credit facility (the “Revolver”) and a $38.0 million fixed asset term loan (the “Term Loan”). The Credit Agreement, as subsequently amended, matures on May 15, 2028 and is secured by substantially all of the assets of the Company and its subsidiaries, including fixed assets and accounts receivable.
The Company has a maximum borrowing capacity under the Revolver of $65.0 million. There is a letter of credit sublimit that is equal to the lesser of $5.0 million and the aggregate unused amount of the revolving commitments then in effect.
The Company is subject to a commitment fee for the unused portion of the maximum borrowing availability under the Revolver. The Revolver termination date is the earlier of the Credit Agreement termination date, May 15, 2028, or the date the outstanding balance is permanently reduced to zero, in accordance with the terms of the Credit Agreement.
As of June 30, 2025, the Company had $10.0 million in borrowings under the Revolver. The Company’s borrowing availability under the Revolver at June 30, 2025 was approximately $21.9 million.
The Credit Agreement is used to finance working capital and general corporate purposes, capital expenditures, permitted acquisitions and associated transaction fees, and to refinance existing indebtedness. Borrowings under the Revolver may be repaid and reborrowed, subject to the borrowing base and other conditions.
As amended, the Revolver and Term Loan bear interest at rates based on 30-day SOFR plus applicable margins, subject to a SOFR floor. As of June 30, 2025, the applicable margin is 4.25% for the Revolver and 6.50% for the Term Loan, with a 4.00% SOFR floor.
The quarterly weighted average interest rate for the Credit Agreement, as of June 30, 2025 and 2024 was 10.46% and 12.07%, respectively.
The Credit Agreement contains customary affirmative and negative covenants, including limitations on indebtedness, liens, investments, asset sales, and dividends, as well as financial maintenance covenants. The financial covenants, as amended, include a minimum Consolidated Fixed Charge Coverage Ratio and/or Consolidated EBITDA thresholds and a minimum liquidity requirement, each tested periodically.
Financial covenants
Restrictive financial covenants under the amended Credit Agreement include:

● A Consolidated Fixed Charge Coverage Ratio to not be less than the following during each noted period:
- Trailing Four Quarter Test Period Ending September 30, 2025 and each Fiscal Quarter thereafter, to not be less than 1.00 to 1.00.

● A Revolver Loan Turnover Ratio to not be less than the following during each noted period:
- Fiscal Quarter Ending June 30, 2023 and each Fiscal Quarter thereafter, to not be less than 2.50 to 1.00.

● A Term Loan Loan-to-Value Ratio to not be greater than the following during each noted period:
- Fiscal Quarter Ending June 30, 2023 and each Fiscal Quarter thereafter, to not be more than 60%.

● A Minimum EBITDA to not be less than the following during each noted period:

- Trailing Four Quarter Test Period ending June 30, 2025 - $31,691,000.

Under the Credit Agreement, the Company may not permit Liquidity (as defined in the Credit Agreement) to fall below $15.0 million (i) for more than three (3) consecutive Business Days (as defined in the Credit Agreement) nor (ii) as of the close of business on Friday of each week.
In addition, the Credit Agreement contains events of default that are usual and customary for similar arrangements, including non-payment of principal, interest or fees; breaches of representations and warranties that are not timely cured; violation of covenants; bankruptcy and insolvency events; and, events constituting a change of control.
The Company was in compliance with all financial covenants under the Credit Agreement as of June 30, 2025.

Other debt
The Company has entered into debt agreements with Mobilease for the purpose of financing equipment purchased. As of June 30, 2025 and December 31, 2024, the carrying value of this debt was $1.2 million and $1.4 million, respectively. The agreements are secured by the financed equipment assets and the debt is included as a component of current debt and long-term debt on the Condensed Consolidated Balance Sheets.
On June 23, 2023, the Company closed on a land-sale leaseback contract for the Company’s Port Lavaca South Yard property located in Port Lavaca, Texas for a purchase price of $12.0 million. A portion of the operating lease above the fair value of the land was financed by the Company. As of both June 30, 2025 and December 31, 2024, the carrying value of this debt was $2.4 million.

Sale-Leaseback Arrangements
On May 15, 2023, the Company entered into a $13.0 million sale-leaseback of certain equipment pursuant to which the Company leased-back the equipment for terms ranging from one to three years. The transaction above was recorded as a failed sale-leaseback.
Concurrent with the sale of Company’s Port Lavaca South Yard property, the Company entered into a twenty-year lease agreement whereby the Company leased back the property at an annual rental rate of approximately $1.1 million, subject to annual rent increases of 2.5%. Under the lease agreement, the Company has four consecutive options to extend the term of the lease by five years for each such option. The portion of the above transaction related to the building was recorded as a failed sale-leaseback.
On September 27, 2019, the Company entered into a purchase and sale agreement (the “Purchase and Sale Agreement”). Pursuant to the terms of the Purchase and Sale Agreement, the Company sold its 17300 and 17140 Market Street location in Channelview, Texas for a purchase price of $19.1 million. Concurrent with the sale of the property, the Company entered into a fifteen-year lease agreement whereby the Company leased back the property at an annual rental rate of approximately $1.5 million, subject to annual rent increases of 2.0%. Under the lease agreement, the Company has two consecutive options to extend the term of the lease by ten years for each such option. The transaction above was recorded as a failed sale-leaseback.
Related to the failed sale-leasebacks, the Company recorded liabilities for the amounts received, will continue to depreciate the non-land portion of the assets, and has imputed an interest rate so that the net carrying amount of the financial liability and remaining assets will be zero at the end of the initial lease terms.

The Company’s effective tax rate is based on expected income, statutory rates and tax planning opportunities available to it. For interim financial reporting, the Company estimates its annual tax rate based on projected taxable income for the full year and records a quarterly tax provision in accordance with the anticipated annual rate.

Income tax (benefit) expense included in the Company’s accompanying Condensed Consolidated Statements of Operations was as follows:

The effective rate for the three and six months ended June 30, 2025 differed from the Company’s statutory federal rate of 21% primarily due to the tax impact from the valuation allowance for current year activity, state income taxes and the non-deductibility of other permanent items.
The Company assessed the realizability of its deferred tax assets and determined that it was more likely than not that some portion or all the deferred tax assets would not be realized and therefore recorded a valuation allowance on the net deferred tax assets. The Company assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. The Company considers the scheduled reversal of deferred tax liabilities, available carryback periods, and tax-planning strategies in making this assessment. For the three and six months ended June 30, 2025 the Company evaluated positive and negative evidence in determining the amount of deferred tax assets more likely than not to be realized. Based on the review of available evidence, management believes that a valuation allowance on the net deferred tax assets at June 30, 2025 remains appropriate.
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes provisions, that may impact our tax rate such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The Company is currently assessing the potential impact on its consolidated financial statements.

Earnings Per Share [Abstract]

Earnings Per Share
12.Earnings Per Share
Basic earnings per share is based on the weighted average number of common shares outstanding during each period. Diluted earnings per share is based on the weighted average number of common shares outstanding as well as the effect of all dilutive common stock equivalents during each period net income is generated. For the three months ended June 30, 2025 and 2024, the Company had 48,940 and 181,025 shares, respectively, that were potentially dilutive in earnings per share calculations. For the six months ended June 30, 2025 and 2024, the Company had 52,103 and 201,550 shares, respectively, that were potentially dilutive in earnings per share calculations. Such dilution is dependent on the excess of the market price of our stock over the exercise price and other components of the treasury stock method. The exercise price for certain stock options awarded by the Company exceeded the average market price of the Company’s common stock for the three and six months ended June 30, 2025 and 2024. Such stock options are antidilutive and are not included in the computation of earnings per share for those periods. The Company reported a net loss for the three months
ended June 30, 2024 and the six months ended June 30, 2025 and 2024; therefore, all potentially dilutive securities are antidilutive and are excluded from the computation of diluted loss per share for such periods.
The following table reconciles the denominators used in the computations of both basic and diluted earnings per share:

Share-Based Compensation
13.Share-Based Compensation
The Compensation Committee of the Company’s Board of Directors is responsible for the administration of the Company’s stock incentive plans. In general, the Company’s 2022 LTIP provides for grants of restricted stock and performance-based awards to be issued with a per-share price not less than the fair market value of a share of common stock on the date of grant. The Company accounts for forfeitures of awards as they are incurred.
In May 2024 shareholders approved the ESPP, which became effective on September 16, 2024. The Company has reserved a total of 1,000,000 shares under the ESPP, all of which are authorized and available for future issuance under the ESPP. During the six months ended June 30, 2025, there were 71,133 shares issued under the ESPP generating proceeds to the Company of $0.3 million. The Company has an outstanding liability pertaining to the ESPP of $0.3 million as of June 30, 2025, included in accrued expenses, for employee contributions to the ESPP, pending issuance at the end of the offering period.

(1) A maximum of 1.2 million common shares could be awarded based upon the Company’s achievement of set performance-metrics.
On March 20, 2025, the Company granted certain executives a total of 293,073 performance-based units. The performance-based units will potentially vest 100% if the target is met, with 50% of the units to be earned based on the achievement of an absolute adjusted EBITDA target, measured in the final year of a three-year performance period and 50% of the units to be earned based on the achievement of an objective, tiered return on relative total shareholder return, measured over a three-year performance period. The Company evaluates the probability of achieving targeted award levels each reporting period. The fair value of the grants awarded related to the adjusted EBITDA target was $5.89 per share and the fair value of the grants awarded related to the relative total shareholder return target was $8.45 valued using a Monte Carlo simulation model.

Segment Information
15.Segment Information
The Company has determined that it has two reportable segments pursuant to ASC Topic 280, Segment Reporting. The tools used by the chief operating decision maker (“CODM”) to allocate resources and assess performance are based on two reportable and operating segments: marine and concrete, which operate under the Orion brand and logo.
In making this determination, the Company considered the similar economic characteristics of each segment’s operations, including internal processes, customer base, regulatory oversight, and macroeconomic factors that drive each. Both the marine and concrete segments have a single individual responsible for managing the entire segment. Resources are allocated by segment and financial and budgetary information is compiled and reviewed by segment.

Marine Segment
Our marine segment provides construction, dredging and specialty services. Construction services include construction, restoration, maintenance, dredging and repair of marine transportation facilities, marine pipelines, bridges and causeways and marine environmental structures. Dredging services generally enhance or preserve the navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. Specialty services include design, salvage, demolition, surveying, towing, diving and underwater inspection, excavation and repair.
Concrete Segment
Our concrete segment provides turnkey concrete construction services, including concrete surface place and finish, site preparation, layout, forming, and rebar placement for large commercial, structural and other associated business areas.

Summary of Significant Accounting Principles (Policies)

Jun. 30, 2025

Accounting Policies [Abstract]

Basis of Presentation
Basis of Presentation
The accompanying condensed consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Accordingly, these financial statements do not include certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and should be read together with our 2024 Annual Report on Form 10-K. For the periods presented, there were no items of other comprehensive income.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows for the periods presented. Such adjustments are of a normal recurring nature. Interim results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results realizable for the year ending December 31, 2025.

Recent Accounting Pronouncements
The Financial Accounting Standards Board (“FASB”) issues accounting standards and updates (each, an “ASU”) from time to time to its Accounting Standards Codification (“ASC”), which is the primary source of U.S. GAAP. The Company regularly monitors ASUs as they are issued and considers applicability to its business. All ASUs are adopted by their respective due dates and in the manner prescribed by the FASB.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments require disclosure of specific categories in the rate reconciliation and provides additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. This will not impact our financial position or results of operations, but is expected to result in expanded tax disclosures in the full year financial statements for the year ended December 31, 2025.
In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The amendments require entities to provide enhanced disaggregation of certain expense categories presented in the income statement, including details on significant
components within those categories, to provide greater transparency and decision-useful information to users of financial statements. The ASU is effective for fiscal years beginning after December 15, 2026, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures within its consolidated financial statements.

Summary of Significant Accounting Principles (Policies)	Jun. 30, 2025
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Accordingly, these financial statements do not include certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and should be read together with our 2024 Annual Report on Form 10-K. For the periods presented, there were no items of other comprehensive income. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows for the periods presented. Such adjustments are of a normal recurring nature. Interim results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results realizable for the year ending December 31, 2025.
Recent Accounting Pronouncements	The Financial Accounting Standards Board (“FASB”) issues accounting standards and updates (each, an “ASU”) from time to time to its Accounting Standards Codification (“ASC”), which is the primary source of U.S. GAAP. The Company regularly monitors ASUs as they are issued and considers applicability to its business. All ASUs are adopted by their respective due dates and in the manner prescribed by the FASB. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments require disclosure of specific categories in the rate reconciliation and provides additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. This will not impact our financial position or results of operations, but is expected to result in expanded tax disclosures in the full year financial statements for the year ended December 31, 2025. In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The amendments require entities to provide enhanced disaggregation of certain expense categories presented in the income statement, including details on significant components within those categories, to provide greater transparency and decision-useful information to users of financial statements. The ASU is effective for fiscal years beginning after December 15, 2026, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures within its consolidated financial statements.
