On October 9, 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the United States Securities and Exchange Commission’s (“SEC”) Disclosure Update and Simplification Initiative, which amends the disclosure or presentation requirements related to various subtopics in the FASB ASC. The effective date is contingent on when the SEC removes the related disclosure from Regulation S-X or Regulation S-K, with early adoption prohibited. The Company does not believe the adoption of the standard will have a material effect on the Company’s consolidated financial position, results of operations or disclosures.

Accounting Policies.

Basis of Consolidation. The consolidated financial statements include the accounts of SEACOR Marine and its controlled subsidiaries. Control is generally deemed to exist if the Company has greater than 50% of the voting rights of a subsidiary. All significant intercompany accounts and transactions are eliminated in the consolidation.

Noncontrolling interests in consolidated subsidiaries are included in the consolidated balance sheets as a separate component of equity. The Company reports consolidated net income (loss) inclusive of both the Company’s and the noncontrolling interests’ share, as well as the amounts of consolidated net income (loss) attributable to each of the Company and the noncontrolling interests. If a subsidiary is deconsolidated upon a change in control, any retained noncontrolling equity investment in the former controlled subsidiary is measured at fair value and a gain or loss is recognized in net income (loss) based on such fair value. If a subsidiary is consolidated upon the business acquisition of controlling interests by the Company, any previous noncontrolled equity investment in the subsidiary is measured at fair value and a gain or loss is recognized in net income (loss) based on such fair value.

The Company employs the equity method of accounting for investments in 50% or less owned companies that it does not control but has the ability to exercise significant influence over the operating and financial policies of the business venture. Significant influence is generally deemed to exist if the Company has between 20% and 50% of the voting rights of a business venture but may exist when the Company’s ownership percentage is less than 20%. In certain circumstances, the Company may have an economic interest in excess of 50% but may not control and consolidate the business venture. Conversely, the Company may have an economic interest less than 50% but may control and consolidate the business venture. The Company reports its investments in and advances to these business ventures in the accompanying consolidated balance sheets as investments, at equity, and advances to 50% or less owned companies. The Company reports its share of earnings from investments in 50% or less owned companies in the accompanying consolidated statements of income (loss) as equity in earnings of 50% or less owned companies.

Certain reclassifications were made to previously reported amounts in the consolidated financial statements and notes thereto to make them consistent with the current period presentation.

7

Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from estimates and those differences may be material.

Revenue Recognition. Revenue is recognized when (or as) the Company transfers promised goods or services to its customers in amounts that reflect the consideration to which the Company expects to be entitled to in exchange for those goods or services, which occurs when (or as) the Company satisfies its contractual obligations and transfers control of the promised goods or services to its customers. The Company recognizes revenue, net of sales taxes, based on its estimates of the consideration the Company expects to receive. Costs to obtain or fulfill a contract are expensed as incurred.

The Company earns revenue primarily from the time charter and bareboat charter of vessels to customers. Since the Company charges customers based upon daily rates of hire, vessel revenues are recognized on a daily basis throughout the contract period. Under a time charter, the Company provides a vessel to a customer and is responsible for all operating expenses, typically excluding fuel. Under a bareboat charter, the Company provides a vessel to a customer and the customer assumes responsibility for all operating expenses and assumes all risks of operation. In the Gulf of America, time charter durations and rates are typically established in the context of master service agreements that govern the terms and conditions of the charter.

In the Company’s operating areas, contracts or charters vary in length from several days to multi-year periods. Many of the Company’s contracts and charters include cancellation clauses without early termination penalties. As a result of cancellations, options and frequent renewals, the stated duration of charters may not correlate with the length of time the vessel is contracted for to provide services to a particular customer.

The Company contracts with various customers to carry out management services for vessels as agents for and on behalf of ship owners. These services include crew management, technical management, commercial management, insurance arrangements, sale and purchase of vessels, provisions and bunkering. As the manager of the vessels, the Company undertakes to use its best endeavors to provide the agreed management services as agents for and on behalf of the owners in accordance with sound ship management practice and to protect and promote the interest of the owners in all matters relating to the provision of services thereunder. The vast majority of the ship management agreements span one to three years and are typically billed on a monthly basis. The Company transfers control of the service to the customer and satisfies its performance obligation over the term of the contract, and therefore recognizes revenue over the term of the contract while related costs are expensed as incurred.

Revenue that does not meet these criteria is deferred and is considered a contract liability and is recognized as such until the criteria are met. Contract liabilities, which are included in unearned revenue in the accompanying consolidated balance sheets, as of March 31, 2026 and December 31, 2025 were as follows (in thousands):

|  | March 31, 2026 |  |  | December 31, 2025 |
Balance at beginning of period |  | $ | 1,096 |  |  | $ | 2,534 |
Unearned revenues during the period |  |  | 6 |  |  |  | 6,935 |
Revenues recognized during the period |  |  | (180 | ) |  |  | (8,373 | )
Balance at end of period |  | $ | 922 |  |  | $ | 1,096 |

As of March 31, 2026 and December 31, 2025, the Company had unearned revenue of $0.9 million and $1.1 million, respectively, primarily related to mobilization of vessels.

Direct Operating Expenses. Direct operating costs and expenses that are considered significant, other than leased-in equipment expense, consist primarily of costs and expenses such as: personnel; repairs and maintenance; drydocking; insurance and loss reserves; and fuel, lubes and supplies. Other direct operating

8

expenses consist of costs such as brokers’ commissions, communication costs, expenses incurred in mobilizing vessels between geographic regions, third party ship management fees, freight expenses, and customs and importation duties. Direct operating costs are expensed as incurred.

Cash and Cash Equivalents. The Company considers all highly liquid investments, with an original maturity of three months or less from the date purchased, to be cash equivalents.

Restricted Cash. Restricted cash primarily relates to banking and credit facility requirements.

Trade and Other Receivables and Allowance for Credit Losses. Customers are primarily major integrated national and international oil companies, large independent oil and natural gas exploration and production companies and established wind farm construction companies. Customers are granted credit on a short-term basis and the related credit risks are minimal. Other receivables consist primarily of operating expenses the Company incurs in relation to vessels it manages for other entities, as well as insurance and income tax receivables. The Company routinely reviews its receivables and makes provisions for expected credit losses utilizing the Current Expected Credit Losses model (“CECL”). The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for loans and other receivables at the time the financial asset is originated or acquired. However, those provisions are estimates and actual results may materially differ from those estimates. After collection efforts have been exhausted, trade receivables that are deemed uncollectible are removed from both accounts receivable and the allowance for credit losses.

Property and Equipment. Equipment, stated at cost, is depreciated using the straight-line method over the estimated useful life of the asset to an estimated salvage value. With respect to each class of asset, the estimated useful life is based upon a newly built asset being placed into service and represents the time period beyond which it is typically not justifiable for the Company to continue to operate the asset in the same or similar manner. From time to time, the Company may acquire older vessels that have already exceeded the Company’s useful life policy, in which case the Company depreciates such assets based on its best estimate of the asset’s remaining useful life, typically the period until the next survey or certification date. As of March 31, 2026, the estimated useful life of the Company’s new offshore support vessels was 20 years.

Equipment maintenance and repair costs and the costs of routine overhauls, drydockings and inspections performed on vessels and equipment are charged to operating expense as incurred. Expenditures that extend the useful life or improve the marketing and commercial characteristics of equipment as well as major renewals and improvements to other properties are capitalized.

Certain interest costs incurred during the construction of equipment are capitalized as part of the assets’ carrying values and are amortized over such assets’ estimated useful lives. There was $1.0 million of capitalized interest recognized during the three months ended March 31, 2026 and no capitalized interest recognized during the three months ended March 31, 2025.

Assets Held for Sale. As of March 31, 2026, one platform supply vessel (“PSV”) and two liftboats previously included in the United States (“U.S.”), primarily Gulf of America segment, with carrying values of $5.5 million, $3.2 million and $3.2 million, respectively, one fast support vessel (“FSV”) previously included in the Africa and Europe segment, with a carrying value of $0.9 million, and one PSV previously included in the Middle East and Asia segment, with a carrying value of $0.5 million, were classified as assets held for sale as the Company expects to sell the vessels within one year.

Impairment of Long-Lived Assets. The Company performs an impairment analysis of long-lived assets used in operations when indicators of impairment are present. These indicators may include a significant decrease in the market price of a long-lived asset or asset group, a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition, or a current period operating or cash flow loss combined with a history of operating or cash flow losses or a forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group. If the carrying values of the assets are not

9

recoverable, as determined by their estimated future undiscounted cash flows, the estimated fair value of the assets or asset groups are compared to their current carrying values and impairment charges are recorded if the carrying value exceeds fair value.

During the three months ended March 31, 2026 and 2025, the Company did no t record impairment charges on any owned vessels. Impairment charges are included in gains (losses) on asset dispositions and impairments in the accompanying consolidated statements of inco me (loss). Estimated fair values for the Company-owned vessels were established by independent appraisers based on researched market information, replacement cost information and other data.

For vessel classes and individual vessels with indicators of impairment as of March 31, 2026, the Company assessed that their estimated fair value exceeds their current carrying values. For any vessel or vessel class that has indicators of impairment and is deemed not recoverable through future operations, the Company determines the fair value of the vessel or vessel class. If the fair value determination is less than the carrying value of the vessel or vessel class, an impairment is recognized to reduce the carrying value to fair value. Fair value determination is primarily accomplished by obtaining independent valuations of vessel or vessel classes from qualified third-party appraisers and other market data such as recent sales of similar vessels.

Impairment of 50% or Less Owned Companies. Investments in 50% or less owned companies are reviewed periodically to assess whether there is an other-than-temporary decline in the carrying value of the investment. In its evaluation, the Company considers, among other items, recent and expected financial performance and returns, impairments recorded by the investee and the capital structure of the investee. When the Company determines the estimated fair value of an investment is below carrying value and the decline is other-than-temporary, the investment is written down to its estimated fair value. Actual results may vary from the Company’s estimates due to the uncertainty regarding projected financial performance, the severity and expected duration of declines in value and the available liquidity in the capital markets to support the continuing operations of the investee, among other factors. Although the Company believes its assumptions and estimates are reasonable, the investee’s actual performance compared with the estimates could produce different results and lead to additional impairment charges in future periods. During the three months ended March 31, 2026 and 2025, the Company did no t recognize any impairment charges related to its 50% or less owned companies.

Income Taxes. During the three months ended March 31, 2026, the Company’s effective income tax rate of 16.2% was primarily due to foreign taxes paid that are not creditable against U.S. income taxes and foreign losses for which there is no benefit in the U.S. for income tax purposes.

Earnings (Loss) Per Share. Basic earnings/loss per share of Common Stock of SEACOR Marine is computed based on the weighted average number of shares of Common Stock and warrants to purchase Common Stock at an exercise price of $0.01 per share (“Warrants”) issued and outstanding during the relevant periods. The Warrants are included in the basic earnings/loss per share of Common Stock because the shares issuable upon exercise of the Warrants are issuable for de minimis cash consideration and therefore not anti-dilutive. Diluted earnings/loss per share of Common Stock is computed based on the weighted average number of shares of Common Stock and Warrants issued and outstanding plus the effect of other potentially dilutive securities through the application of the treasury stock method and the if-converted method that assumes all shares of Common Stock have been issued and outstanding during the relevant periods pursuant to the conversion of the New Convertible Notes unless anti-dilutive. As of June 30, 2025, the Company no longer had any warrants to purchase Common Stock outstanding as a result of the completion of the Securities Repurchase as previously described in the 2025 Annual Report.

For the three months ended March 31, 2026 and 2025, diluted loss per share of Common Stock excluded 1,027,186 and 1,266,954 shares of restricted stock, respectively, and 1,006,365 and 1,008,865 shares of Common Stock, respectively, issuable upon exercise of outstanding stock options, as the effect of their inclusion in the computation would be anti-dilutive.

FAIR VALUE MEASUREMENTS

The fair value of an asset or liability is the price that would be received to sell an asset or transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value and defines three levels of inputs that may be used to measure fair value. Level 1 inputs are quoted prices in active markets

13

for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, or inputs derived from observable market data. Level 3 inputs are unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. The Company had no financial assets and liabilities as of March 31, 2026 and December 31, 2025 that are measured at fair value on a recurring basis.

The estimated fair values of the Company’s other financial assets and liabilities as of March 31, 2026 and December 31, 2025 were as follows (in thousands):

|  |  |  |  | Estimated Fair Value |
March 31, 2026 |  | Carrying Amount |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
LIABILITIES |  |  |  |  |  |  |  |  |  |  |  |
Long-term debt, including current portion |  |  | 327,422 |  |  |  | — |  |  |  | 337,201 |  |  |  | — |
December 31, 2025 |  |  |  |  |  |  |  |  |  |  |  |
LIABILITIES |  |  |  |  |  |  |  |  |  |  |  |
Long-term debt, including current portion |  |  | 334,644 |  |  |  | — |  |  |  | 346,257 |  |  |  | — |

The carrying value of cash, cash equivalents, restricted cash and trade receivables approximates fair value. The fair value of the Company’s long-term debt was estimated based upon quoted market prices or by using discounted cash flow analysis based on estimated current rates for similar types of arrangements. Considerable judgment was required in developing certain of the estimates of fair value, and, accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Company could realize in a current market exchange.

Property and equipment. As of March 31, 2026 and December 31, 2025, the Company recognized no impairment charges on any owned vessels.

COMMITMENTS AND CONTINGENCIES

As of March 31, 2026, the Company had unfunded capital commitments of $44.3 million consisting of $42.3 million in respect of the construction of two PSVs, $1.7 million in respect of two hybrid battery power systems and $0.3 million for miscellaneous vessel equipment. Of the unfunded capital commitments, $26.1 million is payable during the remainder of 2026 and the remainder is payable during 2027. As of March 31, 2026, $30.9 million remained in a restricted account designated to make payments on the construction of the two PSVs, of which $11.3 million was deposited during the first quarter of 2026 from the sale of one PSV, and the remainder from prior vessel sales, in accordance with the terms of the 2024 SMFH Cre dit Facility as previously described in the 2025 Annual Report. Additionally, the 2024 SMFH Credit Facility includes a dedicated $41.0 million tranche that may be used to pay up to 50% of the purchase price of these vessels. $16.4 million of this tranche was drawn as of March 31, 2026, with the remaining $24.6 million of this tranche remaining undrawn and available.

In December 2015, the Brazilian Federal Revenue Office issued a tax-deficiency notice to Seabulk Offshore do Brasil Ltda., an indirect wholly-owned subsidiary of SEACOR Marine (“Seabulk Offshore do Brasil”), with respect to certain profit participation contributions (also known as “PIS”) and social security financing contributions (also known as “COFINS”) requirements alleged to be due from Seabulk Offshore do Brasil (“Deficiency Notice”) in respect of the period of January 2011 until December 2012. In January 2016, the Company administratively appealed the Deficiency Notice on the basis that, among other arguments, (i) such contributions were not applicable in the circumstances of a 70%/30% cost allocation structure, and (ii) the tax inspector had incorrectly determined that values received from outside of Brazil could not be classified as expense refunds. The initial appeal was dismissed by the Brazilian Federal Revenue Office and the Company appealed such dismissal and is currently awaiting an administrative trial. A local Brazilian law has been enacted that

14

supports the Company’s position that such contribution requirements are not applicable, but it is uncertain whether such law will be taken into consideration with respect to administrative proceedings commenced prior to the enactment of the law. Accordingly, the success of Seabulk Offshore do Brasil in the administrative proceedings cannot be assured and the matter may need to be addressed through judicial court proceedings. The potential levy arising from the Deficiency Notice is R$30.5 million based on a historical potential levy of R$12.87 million (USD $5.8 million and USD $2.5 million, respectively, based on the exchange rate as of March 31, 2026).

In the normal course of its business, the Company becomes involved in various other litigation matters including, among others, claims by third parties for alleged property damages and personal injuries. Management has used estimates in determining the Company’s potential exposure to these matters and has recorded reserves in its financial statements related thereto where appropriate. It is possible that a change in the Company’s estimates of that exposure could occur, but the Company does not expect that such changes in estimated costs would have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

Certain of the Company’s subsidiaries are participating employers in two industry-wide, multi-employer, defined benefit pension funds in the United Kingdom: the U.K Merchant Navy Officers Pension Fund (“MNOPF”) and the U.K. Merchant Navy Ratings Pension Fund (“MNRPF”). The Company’s participation in the MNOPF began with the acquisition of the Stirling group of companies (the “Stirling Group”) in 2001 and relates to certain officers employed between 1978 and 2002 by the Stirling Group and/or its predecessors. The Company’s participation in the MNRPF also began with the acquisition of the Stirling Group in 2001 and relates to ratings employed by the Stirling Group and/or its predecessors through today. Both of these plans are in deficit positions and, depending upon the results of future actuarial valuations, it is possible that the plans could experience funding deficits that will require the Company to recognize payroll related operating expenses in the periods invoices are received. As of March 31, 2026, all invoices received related to MNOPF and MNRPF have been settled in full.

COST REDUCTION MEASURES

During the fourth quarter of 2025, the Company initiated certain cost reduction measures to better align its operating expenses with the current state of the offshore marine industry, in general, and its business, in particular. These measures include a reduction of workforce, reorganization of the management structure and streamlining of operations. As a result of the cost reduction measures taken in the fourth quarter of 2025, the Company recognized savings of $1.0 million in wages and benefits expenses for the first quarter of 2026. Management continues to focus on optimizing the cost structure and regional footprint of the business to help maintain the Company’s competitiveness in the industry, improve its operating leverage and position itself to take advantage of market opportunities.

Overview

The Company provides global marine and support transportation services to offshore energy facilities worldwide. As of March 31, 2026, the Company operated a fleet of 43 support vessels, of which all were owned. The primary users of the Company’s services are major integrated national and international oil companies, independent oil and natural gas exploration and production companies, oil field service and construction companies, as well as offshore wind farm operators and offshore wind farm installation and maintenance companies.

The Company operates and manages a diverse fleet of offshore support vessels that (i) deliver cargo and personnel to offshore installations, including offshore wind farms, (ii) assist offshore operations for production and storage facilities, (iii) provide construction, well work-over, offshore wind farm installation and decommissioning support and (iv) carry and launch equipment used underwater in drilling and well installation, maintenance, inspection and repair. Additionally, the Company’s vessels provide emergency response services and accommodations for technicians and specialists.

The Company operates its fleet in four principal geographic regions: the United States (“U.S.”), primarily Gulf of America; Africa and Europe; the Middle East and Asia; and Latin America, primarily in Brazil, Mexico, Guyana, and Central and South America. The Company’s vessels are highly mobile and regularly and routinely move between countries within a geographic region. In addition, the Company’s vessels are redeployed among geographic regions, subject to flag restrictions, as changes in market conditions dictate.

19

Significant items affecting our results of operations

The number and type of vessels operated, their rates per day worked and their utilization levels are the key determinants of the Company’s operating results and cash flows. Unless a vessel is cold-stacked, there is little reduction in daily running costs for the vessels and, consequently, operating margins are most sensitive to changes in rates per day worked and utilization. The Company manages its fleet utilizing a global network of shore side support, administrative and finance personnel.

Offshore oil and natural gas market conditions are highly volatile. For example, oil prices experienced unprecedented volatility during 2020 due to the COVID-19 pandemic and the related effects on the global economy, with the price per barrel going negative for a short period of time. Oil prices steadily increased since the lows hit at the beginning of the COVID-19 pandemic and hit a multi-year high of $122 per barrel during 2022 primarily as a result of the conflict between Russia and Ukraine as well as the related economic sanctions and economic uncertainty but subsequently decreased to pre-conflict levels. During the three months ended March 31, 2026, WTI oil prices reached a high of $105 per barrel and a low of $56 per barrel, ending the period at $102 per barrel. Volatility of oil prices has increased with the onset of the conflict with Iran.

While the Company has experienced difficult market conditions over the past few years due to volatile oil and natural gas prices and the focus of oil and natural gas producing companies on cost and capital discipline, the increases since the lows experienced during the COVID-19 pandemic in oil and natural gas prices has led to an increase in utilization, day rates and customer inquiries about new projects.

The Company closely monitors the availability of vessels in the offshore support vessel market as the utilization and day rates of the Company’s fleet is dependent on the supply and demand dynamics for its vessels. For example, low oil and natural gas prices and a corresponding decline in offshore exploration may reduce demand for the Company’s vessels and in the past such declines have forced many operators in the industry to restructure, liquidate assets or consolidate with other operators. Additionally, the delivery of newly built offshore support vessels to the industry-wide fleet has in the past contributed to an oversupply of vessels in the market, thereby further decreasing the demand for the Company’s existing offshore support vessel fleet. A combination of low customer exploration and drilling activity levels, and excess supply of offshore support vessels whether from laid up fleets or newly built vessels could, in isolation or together, have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and growth prospects. Alternatively, increasing activity levels and a stable supply of offshore support vessels could support higher utilization and day rates and improved financial performance of the Company’s business.

Certain macro drivers somewhat independent of oil and natural gas prices may support the Company’s business, including: (i) underspending by oil and natural gas producers over the last five to ten years leading to pent up demand for maintenance and growth capital expenditures; (ii) improved extraction technologies; and (iii) the need for offshore wind farm support as the industry grows. While the Company expects that alternative forms of energy will continue to develop and add to the world’s energy mix, especially as certain governments, supranational groups, institutional investors, and various other parties focus on climate change causes and concerns, the Company believes that for the foreseeable future demand for gasoline and oil will be sustained, as will demand for natural gas, particularly in the context of expanded power generation demand worldwide. Some alternative forms of energy such as offshore wind farms support some of the Company’s operations and the Company expects such support to increase to the extent that development of these forms of renewable energy expands.

The Company adheres to a strategy of cold-stacking vessels (removing from active service) during periods of weak utilization in order to reduce the daily running costs of operating the fleet, primarily personnel, repairs and maintenance costs, as well as to defer some drydocking costs into future periods. The Company considers various factors in determining which vessels to cold-stack, including upcoming dates for regulatory vessel

20

inspections and related drydocking requirements. The Company may maintain class certification on certain cold-stacked vessels, thereby incurring some drydocking costs while cold-stacked. Cold-stacked vessels are returned to active service when market conditions improve, or management anticipates improvement, typically leading to increased costs for drydocking, personnel, repair and maintenance in the periods immediately preceding the vessels’ return to active service. Depending on market conditions, vessels with similar characteristics and capabilities may be rotated between active service and cold-stack. On an ongoing basis, the Company reviews its cold-stacked vessels to determine if any should be designated as retired and removed from service based on the vessel’s physical condition, the expected costs to reactivate and restore class certification, if any, and its viability to operate within current and projected market conditions. As of March 31, 2026, none of the Company’s 43 owned vessels were cold-stacked worldwide. In addition, the Company had five vessel classified as held for sale as of March 31, 2026.

Recent Developments

Cost Reduction Measures

During the fourth quarter of 2025, the Company initiated certain cost reduction measures to better align its operating expenses with the current state of the offshore marine industry, in general, and its business, in particular. These measures include a reduction of workforce, reorganization of the management structure and streamlining of operations. For the year ended December 31, 2025, the Company incurred one-time charges totaling $1.2 million related to severance charges arising from a reduction in workforce resulting in a decrease in annualized wages and benefits expenses of at least $3.9 million. Management continues to focus on optimizing the cost structure and regional footprint of the business to help maintain the Company’s competitiveness in the industry, improve its operating leverage and position itself to take advantage of market opportunities.

Vessel Sales

On February 24, 2026, the Company completed the sale of one 201 foot, DP-2 platform supply vessel (“PSV”) built in 2015 for total proceeds of $14.6 million for a gain of approximately $7.3 million. Approximately $11.3 million of these sale proceeds were designated to make future payments on the construction of two PSVs and deposited in a restricted account.

On December 19, 2025, the Company completed the sale of one 201 foot, DP-2 platform supply vessel (“PSV”) built in 2013 for total proceeds of $13.4 million for a gain of approximately $8.1 million. Approximately $11.0 million of these sale proceeds were designated to make future payments on the construction of two PSVs and deposited in a restricted account.

On September 29, 2025, the Company completed the sale of the U.S. flag liftboat LB Jill and the U.S. flag liftboat LB Robert (together, the “Liftboat Sales”) for total proceeds of $76.0 million. In addition, concurrently with the closing of the Liftboat Sales, the Company sold certain uninstalled vessel equipment for total proceeds of $1.0 million (the “Equipment Sale”). After deducting transaction costs and expenses, the Company received net cash proceeds of $74.7 million and recognized a gain of $30.5 million for the Liftboat Sales and the Equipment Sale. None of the sale proceeds from the Liftboat Sales and the Equipment Sale are encumbered by the Company’s 2024 SMFH Credit Facility or required to be used to repay such facility.

Direct Vessel Profit. Direct vessel profit (defined as operating revenues less operating expenses excluding leased-in equipment, “DVP”) is the Company’s measure of segment profitability. DVP is a critical financial measure used by the Company to analyze and compare the operating performance of its regions, without regard to financing decisions (depreciation and interest expense for owned vessels vs. lease expense for leased-in vessels). See “Note 11. Segment Information” in the unaudited consolidated financial statements included in Part I. Item 1. “Financial Statements” elsewhere in this Quarterly Report on Form 10-Q.

Current Year Quarter compared with Prior Year Quarter

Operating Revenues. Charter revenues were $0.8 million lower in the Current Year Quarter compared with the Prior Year Quarter. Charter revenues were $1.6 million lower for the Regional Core Fleet, which consists of six vessels, primarily due to lower utilization of 60% in the Current Year Quarter compared to 70% in the Prior Year Quarter and lower average day rates of $21,255 in the Current Year Quarter compared to $22,686 in the Prior Year Quarter. Charter revenues were $0.8 million higher due to the repositioning of two vessels into the region subsequent to the Prior Year Quarter. Other marine services were $1.4 million lower primarily due to lower mobilization revenues. As of March 31, 2026 and 2025, the Company had no vessels cold-stacked in this region.

Direct Operating Expenses. Direct operating expenses were $2.8 million higher in the Current Year Quarter compared with the Prior Year Quarter. Direct operating expenses were $2.5 million higher due to the repositioning of vessels between geographic regions and $0.3 million higher for the Regional Core Fleet primarily due to the timing of certain repair expenditures.

Other Operating Expenses

Lease expense. Leased-in equipment expense for the Current Year Quarter was nearly flat compared to the Prior Year Quarter.

Administrative and general. Administrative and general expenses for the Current Year Quarter were $1.5 million lower compared to the Prior Year Quarter primarily due to decreases in wages and benefits expenses partially offset by increases in allowance for credit losses.

Depreciation and amortization. Depreciation and amortization expense for the Current Year Quarter were $2.5 million lower compared to the Prior Year Quarter due to net fleet changes.

Gains (Losses) on Asset Dispositions and Impairments, Net. During the Current Year Quarter, the Company sold one PSV, previously classified as held for sale, and other equipment for net cash proceeds of $12.8 million, after transaction costs, for a gain of $7.4 million.

Income Tax Expense

During the three months ended March 31, 2026, the Company’s effective income tax rate of 16.2% was primarily due to foreign taxes paid that are not creditable against U.S. income taxes and foreign losses for which there is no benefit in the U.S. for income tax purposes.

Liquidity and Capital Resources

General

The Company’s ongoing liquidity requirements arise primarily from working capital needs, capital commitments and its obligations to service outstanding debt and comply with covenants under its 2024 SMFH Credit Facility. The Company may use its liquidity to fund capital expenditures, make acquisitions or to make other investments. Sources of liquidity are cash balances, cash flows from operations and sales under the Company’s at-the-market offering program entered into on February 7, 2025 (the “ATM Program”), which has approximately $25.0 million of remaining sales capacity as of March 31, 2026. From time to time, the Company may secure additional liquidity through asset sales or the issuance of debt, shares of Common Stock or common stock of its subsidiaries, preferred stock or a combination thereof.

As of March 31, 2026 and March 31, 2025, the Company held balances of cash, cash equivalents and restricted cash totaling $75.4 million and $45.4 million, respectively.

As of March 31, 2026, the Company had outstanding debt of $327.4 million, net of debt discount and issue costs. The Company’s contractual long-term debt maturities as of March 31, 2026, are as follows (in thousands):

As of March 31, 2026, $30.9 million remained in a restricted account designated to make payments on the construction of the two PSVs, of which $11.3 million were deposited during the first quarter of 2026 from the sale of one PSV, and the remainder from prior vessel sales, in accordance with the terms of the 2024 SMFH Credit Facility as previously described in the 2025 Annual Report. Additionally, the 2024 SMFH Credit Facility includes a dedicated $41.0 million tranche that may be used to pay up to 50% of the purchase price of these vessels. $16.4 million of this tranche was drawn as of March 31, 2026, with the remaining $24.6 million of this tranche remaining undrawn and available.

•
capital expenditures were $6.1 million; and
•
the Company sold one PSV, previously classified as held for sale, and other equipment for net cash proceeds of $12.8 million, after transaction costs, for a gain of $7.4 million.

33

During the Prior Year Quarter, net cash used in investing activities was $12.3 million, primarily as a result of the following:

Financing Activities

During the Current Year Quarter, net cash used in financing activities was $9.2 million, primarily as a result of the following:

•

Short and Long-Term Liquidity Requirements

The Company believes that a combination of cash balances on hand, cash generated from operating activities and access to the credit and capital markets, including the $25.0 million in remaining sales capacity under the ATM Program, will provide sufficient liquidity to meet its obligations, including to support its capital expenditures, working capital needs, debt service requirements and covenant compliance over the short to long term. With respect to the remaining $42.3 million in capital expenditures related to the construction of two PSVs, up to $24.6 million remains available under Tranche B of the 2024 SMFH Credit Facility and $30.9 million of proceeds from vessel sales remained in a restricted account designated for these capital expenditures as of March 31, 2026. The Company continually evaluates possible acquisitions and dispositions of certain businesses and assets. The Company’s sources of liquidity may be impacted by the general condition of the markets in which it operates and the broader economy as a whole, which may limit its access to or the availability of the credit and capital markets on acceptable terms. Management continuously monitors the Company’s liquidity and compliance with covenants in its 2024 SMFH Credit Facility.

Evaluation of Disclosure Controls and Procedures

With the participation of the Company’s principal executive officer and principal financial officer, management evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of March 31, 2026. Based on their evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2026 to provide reasonable assurance that information required to be disclosed by the Company in reports filed or submitted under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the United States Securities and Exchange Commission’s (“SEC”) rules and forms and (ii) accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Therefore, even those internal control systems determined to be effective can provide only a level of reasonable assurance with respect to financial statement preparation and presentation.

Changes in Internal Control Over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the Current Year Quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
