Recently Adopted Accounting Standards.

On November 27, 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities to disclose information about their reportable segments’ significant expenses on an interim and annual basis. The guidance is effective for fiscal years beginning after December 15, 2023 and interim periods within the fiscal years beginning after December 15, 2024. The Company adopted the standard as of December 31, 2024 and the adoption of the standard did not have a material effect on the Company’s consolidated financial position, results of operations or disclosures.

Recently Issued Accounting Standards.

On December 14, 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities to disclose, on an annual basis, information about their effective tax rate reconciliation and information on income taxes paid. The guidance is effective for fiscal years beginning after December 15, 2024. While early adoption is permitted, the Company has determined it will not early adopt the standard. The Company does not believe the adoption of the standard will have a material effect on the Company’s consolidated financial position or results of operations.

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 Accounting Standards Codification. 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.

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 combination and 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, net of tax.

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.

Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S.”) 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 over 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 U.S. 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 Company also contracts with various customers to carry out management services regarding engineering for vessel construction and vessel conversions. 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.

As of March 31, 2025 and December 31, 2024, the Company had unearned revenue of $2.5 million and $2.5 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 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, 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, 2025, 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 no capitalized interest recognized during the three months ended March 31, 2025 or 2024.

Assets Held for Sale. As of March 31, 2025, one fast support vessel (“FSV”), with a carrying value of $1.5 million, one platform support vessel (“PSV”), with a carrying value of $5.4 million, both previously included in the Middle East and Asia segment, and one PSV, with a carrying value of $5.3 million, previously included in the United States (primarily Gulf of America) segment, were classified as assets held for sale and subsequently sold during the second quarter of 2025. See “Note 12. Subsequent Events” in the unaudited consolidated financial statements elsewhere in this Quarterly Report on Form 10-Q.

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 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, 2025 and 2024, the Company did not record impairment charges on any owned or leased-in vessels. Impairment charges are included in gains (losses) on asset dispositions and impairments in the accompanying consolidated statements of income (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, 2025, the Company estimated that their future undiscounted cash flows exceeded their current carrying values. However, the Company’s estimates of future undiscounted cash flows are highly subjective as utilization and rates per day worked are uncertain, especially in light of the continued volatility in commodity prices as well as the timing and cost of reactivating cold-stacked vessels. If market conditions decline, changes in the Company’s expectations on future cash flows may result in recognizing additional impairment charges related to its long-lived assets in future periods.

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.

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, 2025 and 2024, the Company did not recognize any impairment charges related to its 50% or less owned companies.

Income Taxes. During the three months ended March 31, 2025, the Company’s effective income tax rate of 5.8% 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 for U.S. 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 December 31, 2024, the Company no longer had New Convertible Notes as a result of the completion of the 2024 SMFH Credit Facility as previously described in the 2024 Annual Report. See “Note 12. Subsequent Events” in the unaudited consolidated financial statements elsewhere in this Quarterly Report on Form 10-Q.

For the three months ended March 31, 2024, diluted loss per share of Common Stock excluded 2,978,724 shares of Common Stock issuable upon conversion of the New Convertible Notes as the effect of their inclusion in the computation would be anti-dilutive.

In addition, for the three months ended March 31, 2025 and 2024 diluted loss per share of Common Stock excluded 1,266,954 and 1,378,797 shares of restricted stock, respectively, and 1,008,865 and 1,016,865 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.
