These condensed consolidated financial statements should be read in conjunction with the Company’s financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Annual Report”).

Unless the context otherwise indicates, any reference in this Quarterly Report on Form 10-Q to the “Company” refers to SEACOR Marine Holdings Inc. and its consolidated subsidiaries, and any reference in this Quarterly Report on Form 10-Q to “SEACOR Marine” refers to SEACOR Marine Holdings Inc. without its consolidated subsidiaries.

On October 29, 2020, the FASB issued ASU 2020-10, Codification Improvements: Amendments that improve the consistency of the Codification by including all disclosure guidance in the appropriate Disclosure section. The guidance was effective for annual periods beginning after December 15, 2020, and interim periods within the annual periods beginning after December 15, 2022. The adoption of the standard did not have a material effect on the disclosures included herein.

On August 5, 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021. The Company adopted the new standard on January 1, 2022. The adoption of the standard by the Company did not have a material impact on its consolidated financial position or on its results of operations, cash flows and disclosures.

On December 18, 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The adoption of the standard by the Company did not have a material impact on its consolidated financial position or on its results of operations and cash flows.

On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The ASU is intended to help stakeholders during the global market-wide reference rate transition period. Therefore, it will be in effect for a limited time through December 31, 2022. As of March

31, 2022, the reference rates for the Company’s existing debt and interest rate swaps have not changed as a result of any such amendment. The Company will continue to monitor changes to reference rates in applicable agreements and adopt the standard as needed.

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 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. Such estimates include those related to deferred revenues, allowance for credit loss accounts, useful lives of property and equipment, impairments, income tax provisions and certain accrued liabilities. 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 Mexico, time charter durations and rates are typically established in the context of master service agreements that govern the terms and conditions of the charter. From time to time, the Company may also participate in pooling arrangements. In a pooling arrangement, the time charter revenues of certain of the Company’s vessels are shared with the time charter revenues of certain vessels of similar type owned by non-affiliated vessel owners based upon an agreed formula.

Contract or charter durations may range from several days to several years. Charters vary in length from short-term to multi-year periods, many with cancellation clauses and without early termination penalties. As a result of options and frequent renewals, the stated duration of charters may have little correlation with the length of time the vessel is contracted to provide services to a particular customer.

The Company also 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 efforts 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.

Revenue that does not meet these criteria is deferred until the criteria is met and is considered a contract liability and is recognized as such. Contract liabilities, which are included in other current liabilities in the accompanying consolidated balance sheets, for the three months ended March 31, 2022 and three months ended March 31, 2021 were as follows (in thousands):

	2022		2021
Balance at beginning of period	$	321	$	3,307
Revenues deferred during the period		—		50
Revenues recognized and reclassifications during the period		—		(730	)
Balance at end of period	$	321	$	2,627

As of March 31, 2022, the Company had deferred revenues of $0.3 million primarily comprised of prepaid charter modification and reservations.

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 facility requirements.

Trade and Other Receivables. Customers are primarily major integrated national and international oil companies and large independent oil and natural gas exploration and production 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 the 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. Trade receivables are deemed uncollectible and are removed from accounts receivable and the allowance for credit losses when collection efforts have been exhausted.

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 remaining useful life, typically the next survey or certification date. As of March 31, 2022, the estimated useful life (in years) 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, 2022. During the three months ended March 31, 2021 capitalized interest totaled $0.2 million.

Impairment of Long-Lived Assets. The Company performs an impairment analysis of long-lived assets used in operations, including intangible assets, 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.

For the three months ended March 31, 2022, the Company recorded impairment charges of $0.9 million related to one fast support vessel (“FSV”) classified as held for sale as of March 31, 2022, which was included in the Africa and Europe segment with a carrying value of $2.3 million. There were no impairments of other owned or leased-in vessels. For the three months ended March 31, 2021, the Company did not record an impairment on any owned or leased-in vessels. 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, 2022, 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 continue to 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, 2022 and 2021, 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, 2022, the Company’s effective income tax rate of 10.56% was primarily due to foreign taxes not creditable against U.S. income taxes and foreign losses for which there is no benefit in the U.S.

Accumulated Other Comprehensive Income (Loss). The components of accumulated other comprehensive loss were as follows (in thousands):

	SEACOR Marine Holdings Inc. Stockholders’ Equity
	Foreign Currency Translation Adjustments			Derivative Gains (Losses) on Cash Flow Hedges, net			Total Other Comprehensive Income
December 31, 2021	$	10,783		$	(2,728	)		8,055
Other comprehensive (loss) income		(714	)		1,512			798
Balance as of March 31, 2022	$	10,069		$	(1,216	)	$	8,853

Earnings (Loss) Per Share. Basic earnings/loss per share of Common Stock of the Company 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 Convertible Senior Notes (as defined in “Note 4. Long-Term Debt”) unless anti-dilutive.

The Company’s Convertible Senior Notes (“Convertible Senior Notes”) are currently convertible into 2,907,500 shares of Common Stock. For the three months ended March 31, 2022 and 2021, diluted loss per share of Common Stock excluded 2,907,500 issuable upon conversion of the Convertible Senior Notes and exercise of the related Warrants as the effect of their inclusion in the computation would be anti-dilutive. The number of shares of Common Stock issuable upon conversion of the Convertible Senior Notes and exercise of the related Warrants excluded from the calculation of diluted earnings/loss per share was incorrectly reported in certain prior periods as 2,183,708. This number of shares was adjusted in the period ended June 30, 2021 following revisions to the calculation.

In addition, for the three months ended March 31, 2022 and 2021 diluted loss per share of Common Stock excluded 1,469,647 and 1,059,077 shares of restricted stock, respectively, and 1,029,365 and 1,120,541 shares of stock, respectively, issuable upon exercise of outstanding stock options as the effect of their inclusion in the computation would be anti-dilutive.

Subsequent events. The Company has evaluated subsequent events through May 4, 2022, the date the financial statements were issued. Any material subsequent events that occurred during this time have been properly recognized and/or disclosed in these financial statements.
