Our geographic reach spans availability. With one of the largest and most diverse fleets of offshore marine support vessels, we deliver a complete suite of transport services to meet the full lifecycle needs of offshore energy. Whether offshore or onshore, safety drives our operations everywhere, every day. SEACOR Marine | 1 Leading. Succeeding. Dear Fellow Stockholder, The past year saw significant improvement in our business and capital structure. We generated positive cash flow from operations in 2023 and refinanced a significant portion of our secured debt into a new five-year facility, greatly simplifying and strengthening our capital structure. We enter 2024 on solid footing and expect the improvement to continue. The durability of this upturn and whether we are at the beginning of a sustained “super” cycle are questions we are frequently asked. On the positive side, the supply of new vessels is very limited (a few specialized vessels are the only current order book) and supply is likely to remain constrained for the next 3-5 years. This period could be longer since access to financing, especially for newbuilds, continues to be very limited. Lastly, supply is in the industry’s control and the scars from the prolonged downturn are recent enough to limit ordering for a while. Demand, especially the durability of demand, is more difficult to predict. Offshore oil and gas projects and their related equipment, particularly new developments (vs. expansion of existing fields), are long cycle investments challenged by the speed and mix of the energy transition. Offshore wind is also a long cycle investment but backed by the conviction of a growing share of the energy market in the coming decades. The good news is the overall demand for energy is expected to continue to grow so all forms of energy are sharing a larger pie. We have positioned SEACOR Marine to have a young fleet compared to its peers, with the flexibility to service a wide range of geographic areas supporting multiple uses. From oil and gas activities, such as exploration, production, well plug and abandonment, and the decommissioning of offshore platforms and pipelines, to offshore wind development in the U.S., our fleet is able to capitalize on these opportunities. We think this is the best hedge at a time when clear long term demand trends are still developing in our industry. While time will tell if this is a “super” cycle for the industry, we have done our best to position SEACOR Marine for whatever the future may hold. Our dedicated team of professionals, both at sea and ashore, are responsible for making this vision a reality and I thank them for their continuing dedication and support. John Gellert President and Chief Executive Officer SEACOR Marine | 3 Financial Summary Fiscal Year Ended December 31, 2023 2022 2021 2020 2019 $ $ 279,511 35,518 $ $ 217,325 (53,999) $ $ 170,941 $ 141,837 $ 174,453 (37,148) $ (71,639) (54,328) From continuing operations (U.S. dollars in thousands) Operating Revenues Operating Income (Loss) Other (Expenses) Income: Net Interest Expense $ (36,060) $ (28,922) $ (26,809) $ (29,418) $ (27,567) (Losses) Gains on Debt Extinguishment (2,004) 10,429 61,944 Derivative Gains, Net Other 608 – (2,133) 2,414 391 8,199 – 4,310 – 71 (1,360) (2,650) Other (Expense) Income, Net $ (39,589) $ (16,079) $ 43,775 $ (26,468) $ (30,146) Net (Loss) Income Attributable to SEACOR Marine Holdings Inc.

Business The Company provides global marine and support transportation services to offshore energy facilities worldwide. 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, (iv) carry and launch equipment used underwater in drilling and well installation, maintenance, inspection and repair, and (v) handle anchors and mooring equipment for offshore rigs and platforms. Additionally, the Company’s vessels provide emergency response services and accommodations for technicians and specialists. On January 12, 2021, the Company completed the announced sale of Windcat Workboats Holdings Limited (“Windcat Workboats”), the Company’s indirect wholly owned subsidiary, and the crew transfer vessel (“CTV”) business of Windcat Workboats (the “Windcat Workboats CTV Business”), which was previously classified as assets held for sale as of the end of the fourth quarter 2020. Unless the context indicates otherwise, the results for all periods presented exclude the CTV operations of the Windcat Workboats CTV Business which are classified as CTV - Discontinued Operations. 1 For a discussion of risk and economic factors that may impact the Company’s financial position and its results of operations, see “Item 1A. Risk Factors” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Annual Report on Form 10-K. Equipment and Services The following tables identify the types of vessels that comprise the Company’s fleet as of December 31 for the indicated years. “Owned” are majority owned and controlled by the Company. “Joint-Ventured” are owned or operated by entities in which the Company does not have a controlling interest. “Leased-in” may either be vessels contracted from leasing companies to which the Company may have sold and leased back such vessels or vessels chartered-in from other third party owners. “Managed” are owned by entities not affiliated with the Company but operated by the Company for a fee. A description of vessel classes follows this table. Owned Joint- Ventured (1) Leased - in Managed Total Average Age Owned Fleet U.S.- Flag Foreign- Flag 2023 (2) PSV FSV Liftboats AHTS PSV FSV Liftboats AHTS PSV FSV Liftboats (3) AHTS Specialty (4) 2022 2021 21 22 8 3 54 21 22 9 3 55 20 23 9 4 1 57 — — — — — — — — — — 15 5 — — — 20 — — — 1 1 — 1 — 2 3 — 1 — 2 — 3 — 3 — — 3 — 2 — — 2 — 1 — — — 1 21 25 8 4 58 21 25 9 5 60 35 30 9 6 1 81 7 11 13 14 10 6 10 12 13 9 5 9 11 13 13 8 5 6 6 — 17 5 5 7 — 17 5 5 7 1 — 18 16 16 2 3 37 16 17 2 3 38 15 18 2 3 1 39 (1) (2) (3) (4) In the third quarter of 2022, the Company sold its equity interests in each of MexMar and OVH (as each are defined in “Markets” below) and acquired 100% of the equity interest in SEACOR Marlin LLC, resulting in the Company no longer operating any joint-ventured vessels. As of December 31, 2023, 51 of the Company’s owned and leased-in vessels were outfitted with dynamic positioning (“DP”) systems. DP systems enable vessels to maintain a fixed position in close proximity to a rig or platform. The most technologically advanced DP systems have enhanced redundancy in the vessel’s power, electrical, computer and reference systems enabling vessels to maintain accurate position-keeping even in the event of failure of one of those systems (“DP-2”) and, in some cases, in the event of fire and flood (“DP-3”). In the second quarter of 2021, the Company removed from service four liftboats. Removed from service vessels are not counted in the active fleet count and therefore not reflected in the above table. One owned vessel classified as a CTV - Continuing Operations as of December 31, 2020, was reclassified as a specialty vessel as of January 12, 2021, and then removed from service in the second quarter of 2022. The vessels categorized as CTV - Discontinued Operations in 2020 primarily consisted of the Windcat Workboats CTVs sold in January 2021. Platform supply vessels (“PSVs”) generally range from 190 to more than 300 feet in length and are primarily used to deliver general cargo, drilling fluids, bulk products, methanol, diesel fuel and water to rigs and platforms where drilling and work-over activity is underway. These vessels can be modified for a wide variety of other uses and missions, including, but not limited to, construction support (typically when fitted with a crane), standby, security, firefighting, and accommodation. Relevant differentiating features of PSVs are total carrying capacity (expressed as deadweight: “dwt”), available area of clear deck space, below-deck capacity for storage of mud and bulk products used in the drilling process, tank storage for water and fuel oil, accommodation capacity and fuel efficiency. To improve fuel efficiency, reduce carbon and other emissions, and provide greater redundancy, PSVs are sometimes equipped with hybrid battery power systems. As of December 31, 2023, six of the 21 owned PSVs were equipped with hybrid battery power systems. The Company has also committed to additional hybrid battery power systems to be installed on five PSVs in 2024 and 2025. Additional factors in the commercial marketability of PSVs are operating draft because certain markets are limited in the size of vessel that can work safely, local flag preference, cabotage requirements and regulations. To improve station keeping ability, many modern PSVs have DP systems capabilities. As of December 31, 2023, all 21 of the owned PSVs were equipped with DP-2. 2 Fast support vessels (“FSVs”) are aluminum hull vessels used primarily to move cargo and personnel to and from offshore drilling rigs, platforms and other installations at greater speeds than traditional steel hull support vessels. FSVs can be catamaran or mono-hull vessels ranging from 145 to 205 feet in length and capable of speeds between 20 to 45 knots with capacities to carry special cargo, support both drilling operations and production services and transport passengers. The Company’s FSV fleet includes vessels that have a passenger capacity of 36 to 150 and, on certain newer FSVs, include reclining seating, ambient lighting and other features to enhance the comfort and marketability of the FSV for passenger transport. FSVs built within the last ten years are sometimes equipped with DP-2 systems, firefighting equipment, hospitals, walk to work and ride control systems for greater comfort and performance. As of December 31, 2023, 20 of the 22 owned FSVs were equipped with DP-2 and two were equipped with DP-3. We have been a pioneer in improving the fuel efficiency of FSVs. For instance, our FSV fleet is comprised of vessels with semi-displacement hulls and many of our vessels include ride control technology that optimizes vessel trim and dampens acceleration to reduce fuel consumption. We have also been exploring additional means to cut down on fuel consumption of FSVs, such as through the installation of whole hull ultrasonic antifouling systems. This antifouling technology is currently on 17 of our FSVs. In addition to its existing fleet of FSVs, as of December 31, 2023, the Company has a construction project in progress for one U.S.-flag, DP-2 FSV with an undetermined delivery date as the Company, at its option, may defer its construction for an indefinite period of time. Liftboats provide a self-propelled, stable platform to perform offshore wind farm installation and maintenance, production platform construction, inspection, maintenance and removal, well intervention and work-over, well production enhancement, well plug and abandonment, pipeline installation and maintenance and diving operations. The length of jacking legs (235 feet to 335 feet for the Company’s liftboats) determines the water depth in which these vessels can work. Other differentiating features are crane lifting capacity and reach, clear deck area, helipad and electrical generating power and accommodation capacity. Liftboats are used in all of our operating areas. As of December 31, 2023, three of the eight owned liftboats were equipped with DP-2, one with DP-1 and the remaining liftboats were not equipped with DP. Liftboats can support projects while elevated out of the water, shutting down all main engines and relying on one generator during the project, realizing a significant reduction in fuel consumption over vessels that can perform similar missions but that would have to run all engines for the same performance. Anchor handling towing supply vessels (“AHTS”) are used primarily to support offshore drilling activities by towing, positioning and mooring drilling rigs and other marine equipment. AHTS are also used to carry and launch equipment such as remote operated vehicles (“ROVs”) used underwater in drilling and well installation, maintenance, and repair and transport supplies and equipment from shore bases to offshore drilling rigs, platforms and other installations, including floating offshore wind farm installations. The defining characteristics of AHTS are: (i) horsepower (“bhp”); (ii) Bollard pull, which is the pulling capacity of the AHTS and is important for towing and positioning rigs; (iii) winch size in terms of “line pull” and brake holding capacity; and (iv) wire storage capacity. The Company’s fleet of AHTS has varying capabilities and supports offshore mooring activities in water depths ranging from 300 to 8,000 feet. Most modern AHTS are equipped with DP systems and can also carry drilling fluids and bulk products below- deck. As of December 31, 2023, all four of the Company’s owned and leased-in AHTS were equipped with DP-2. Specialty vessels include anchor handling tugs, accommodation, line handling and other vessels. These vessels generally have specialized features adapting them to specific applications including offshore maintenance and construction services, freight hauling services and accommodation services. The Company has not had any specialty vessels in its active fleet since the second quarter of 2022. Markets The Company operates its fleet in four principal geographic regions: the United States (“U.S.”), primarily in the Gulf of Mexico; Africa and Europe; the Middle East and Asia; and Latin America, primarily in Mexico and Guyana. 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. 3 The table below sets forth vessel types by geographic market as of December 31 for the indicated years. The Company sometimes participates in joint venture arrangements in certain geographical locations in order to enhance marketing capabilities and facilitate operations in certain foreign markets or if otherwise required by law allowing for the expansion of its fleet and operations while diversifying risks and reducing capital outlays associated with such expansion. Since September 2022, the Company has not participated in any joint ventures that own or lease in vessels. Over the past three years, the Company has worked diligently to right size through vessel sales and exiting from joint ventures, and configure its fleet to meet the demands of its markets, including by focusing on environmental stewardship through the reconfiguration of vessels to utilize hybrid battery power systems. In addition, the Company’s fleet reconfiguration has enabled it to meet its goals of focusing on the highest margin vessels and deployments. The Company believes its smaller fleet, together with a simplified capital structure, will allow it to react more quickly and dynamically to a variety of investment opportunities in its industry. 2023 2022 2021 United States, primarily U.S. Gulf of Mexico: PSV FSV Liftboats AHTS Africa and Europe, continuing operations: PSV FSV AHTS Middle East and Asia: PSV FSV Liftboats AHTS Specialty Latin America: PSV FSV Liftboats Total Foreign Fleet Total Fleet 2 5 6 — 13 6 10 3 19 5 8 2 1 — 16 8 2 — 10 45 58 3 5 7 1 16 6 10 3 19 5 8 2 1 — 16 7 2 — 9 44 60 3 4 6 2 15 3 10 3 16 7 9 2 1 1 20 22 7 1 30 66 81 United States, primarily U.S. Gulf of Mexico. As of December 31, 2023, 13 vessels were located in this region, including 11 owned and two managed. The Company’s vessels in this market consist primarily of a fleet of FSVs, PSVs and liftboats that support oil and natural gas exploration and production activities, seasonal construction, decommissioning and diving support operations, as well as the construction and maintenance of offshore wind farms in the Northeast of the U.S. Africa and Europe, continuing operations. As of December 31, 2023, 19 vessels were located in this region, including 18 owned and one leased-in. The Company’s vessels in this market generally support projects for major oil companies primarily in Angola, Senegal, Namibia, Nigeria and the North Sea. On January 12, 2021, the Company completed the sale of its Windcat Workboats CTV Business, comprised of 46 CTVs (45 active vessels and one vessel previously removed from service) located in Europe providing crew transfer to offshore wind farms. Middle East and Asia. As of December 31, 2023, 16 vessels were located in this region, including 15 owned and one managed. The Company’s vessels in this area generally support exploration, personnel transport and seasonal construction activities in Saudi Arabia, United Arab Emirates, Qatar and Egypt. 4 Latin America. As of December 31, 2023, ten vessels were located in this region, all of which were owned. These vessels consist of a fleet of FSVs and PSVs that provide support for exploration and production activities primarily in Mexico, Guyana and Trinidad and Tobago. From time to time, the Company’s vessels also work in Brazil and Colombia. On September 29, 2022, the Company sold its equity interests in Mantenimiento Express Marítimo, S.A.P.I. de C.V. (“MexMar”), and Offshore Vessels Holding, S.A.P.I. de C.V. (“OVH”), and acquired 100% of the equity interest in SEACOR Marlin LLC. As a result, the Company no longer operates 19 of the joint-ventured vessels owned by MexMar and OVH, and acquired one previously joint-ventured vessel owned by SEACOR Marlin LLC. Seasonality The demand for the Company’s fleet can fluctuate with weather conditions because maintenance, construction and decommissioning activities are planned during times of the year with more favorable weather conditions. Seasonality is most pronounced for the liftboat fleet in the United States and offshore support vessels in Europe, Middle East and West Africa, with peak demand normally occurring during the summer months. As a consequence of this seasonality, the Company typically schedules drydockings or other repair and maintenance activity during the winter months. Customers and Contractual Arrangements The Company’s principal customers 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. For oil and natural gas customers, the volatility of commodity prices and an increased focus on capital discipline (e.g., limiting spending to existing free cash flow and prioritizing returning money to shareholders) could limit their field development and production activities which utilize the Company’s services, as these companies continue to focus on increasing or maintaining efficiency, controlling costs and delaying or abandoning exploration activity and facilities with less promise. However, some of our oil and natural gas customers are increasing their capital expenditures in response to higher post-pandemic demand for energy and are increasing their focus on reliable and secure energy sources while maintaining capital discipline. Additionally, increasing offshore wind farm development, particularly in the Northeast of the U.S., has provided opportunities for the Company to work with new customers. During the year ended December 31, 2023, three customers, ExxonMobil Corporation (“ExxonMobil”), SEACOR Marine Arabia LLC (“SEACOR Marine Arabia”), a joint venture that is 45% owned by a subsidiary of SEACOR Marine and through which vessels are in service to Saudi Arabian Oil Company (“Saudi Aramco”), and Azule Energy Angola S.p.A. (“Azule”), a joint venture between BP p.l.c. and Eni S.p.A., were each responsible for over 10% of the Company’s consolidated operating revenues from continuing operations. ExxonMobil, SEACOR Marine Arabia and Azule were responsible for 17%, 15% and 15%, respectively, of the Company’s consolidated revenues from continuing operations in 2023. The Company’s ten largest customers accounted for approximately 73% of the consolidated revenues from continuing operations in 2023. The loss of one or more of these customers could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. 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. 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. Competitive Conditions The market for offshore marine services is highly fragmented and competitive depending upon the region of operation. The most important competitive factors are pricing, availability and specifications of equipment to fit customer requirements. Other important factors include service, reputation, flag preference, local marine operating and regulatory conditions, the ability to provide and maintain logistical support given the complexity of a project, and the cost of moving equipment from one geographic region to another. The Company has numerous competitors in each of the geographic regions in which it operates, ranging from international companies that operate in many regions to smaller local companies that typically concentrate their activities in one specific country or region. 5 Risks of Foreign Operations For the years ended December 31, 2023, 2022, and 2021, 79%, 72%, and 88%, respectively, of the Company’s operating revenues from continuing operations and $3.6 million, $7.0 million and $15.4 million, respectively, of the Company’s equity in earnings from 50% or less owned companies, net of tax, were derived from its foreign operations. Foreign operations are subject to inherent risks, which, if they materialize, could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows or prospects. See the risk factors regarding international operations in “Item 1A. Risk Factors” of this Annual Report on Form 10-K. Government Regulation The Company’s ownership, operation, construction and staffing of vessels is subject to significant regulation under various international, federal, state and local laws, regulations and conventions, including international conventions and ship registry laws of the nations under which the Company’s vessels are flagged, especially with respect to foreign ownership, health, safety, environmental protection and vessel and port security. The following summary is intended to highlight key regulations applicable to the Company’s operations and vessels, and is not intended to be comprehensive. The Company does not expect that it will be required to make capital expenditures in the near future to comply with applicable laws and regulations that would have a material adverse effect on its financial position, results of operations, cash flows or prospects. The Company is subject to extensive federal, state, local and international environmental and safety laws and regulations and to comprehensive international conventions, including laws and regulations related to the discharge of oil and pollutants into waters regulated thereunder. Violations of these laws may result in civil and criminal penalties, fines, injunctions, or other sanctions, any of which could be material. However, because such laws and regulations frequently change and may impose increasingly strict requirements, the Company cannot predict the ultimate cost of complying with these laws and regulations. Regulatory Matters Most of the vessels operated by the Company are registered in foreign jurisdictions, with the remainder registered in the U.S. Vessels are subject to the laws of the applicable jurisdiction of registration regarding several matters, including ownership, manning, environmental protection and safety. In addition, the Company’s vessels are subject to the requirements of a number of international conventions that are applicable to vessels depending on their jurisdiction of registration. Among the more significant of these conventions are: (i) the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto (“MARPOL”); (ii) the International Convention for the Safety of Life at Sea, 1974 and 1978 Protocols (“SOLAS”); (iii) the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (“STCW”); (iv) the Maritime Labour Convention, 2006 (the “MLC”); and (v) the International Ship and Port Facility Security Code (the “ISPS Code”). Domestically registered vessels are subject to the jurisdiction of the U.S. Coast Guard (“USCG”), the U.S. Customs and Border Protection (“CBP”), the U.S. Environmental Protection Agency (“EPA”) and the U.S. Maritime Administration (“MARAD”), as well as in certain instances applicable state and local laws. The Company’s operations may be, from time to time, regulated by the U.S. Bureau of Safety and Environmental Enforcement (“BSEE”) and its Safety and Environmental Management System regulations, and the Company must also periodically certify that its maritime operations adhere to those regulations. These agencies and organizations establish safety requirements and standards and, together with the National Transportation Safety Board (“NTSB”), are authorized to investigate vessels and accidents and to recommend improved maritime safety standards. The Company is also subject to the requirements of the Occupational Safety and Health Act, and comparable state laws and regulations that govern the protection of the health and safety of employees. The Company is subject to regulation under the U.S. Merchant Marine Act of 1920 (“Jones Act”) and related U.S. cabotage laws, which restrict ownership and operation of vessels in the U.S. coastwise trade (defined as trade between points in the U.S.), including the transportation of cargo. Subject to limited exceptions, the Jones Act requires that vessels engaged in U.S. coastwise trade be built in the U.S., registered under the U.S.-flag, manned by predominantly U.S. crews, and be owned, operated and controlled by U.S. citizens. Violation of the Jones Act could prohibit operation of vessels in the U.S. coastwise trade during the period of such non- compliance, result in material fines and subject Company vessels to seizure and forfeiture. 6 SEACOR Marine’s Third Amended and Restated Certificate of Incorporation and Third Amended and Restated By-Laws include various provisions designed to facilitate compliance with the Jones Act, including provisions that: (i) limit the aggregate percentage ownership by non-U.S. citizens of any class of SEACOR Marine’s capital stock (including Common Stock) to 22.5% of the outstanding shares of each such class to ensure that ownership by non-U.S. citizens will not exceed the maximum percentage permitted by applicable maritime law (presently 25%) but authorize the Board of Directors, under certain circumstances, to increase the foregoing percentage to 24%; (ii) permit the use of a dual stock certification system to help determine such ownership; (iii) provide that any issuance or transfer of shares in excess of such permitted percentage shall be ineffective as against SEACOR Marine and prohibit SEACOR Marine and its transfer agent from registering such purported issuance or transfer of shares or be required to recognize the purported transferee or owner as a stockholder of SEACOR Marine for any purpose whatsoever except to exercise its remedies; (iv) provide that the purported transferee of any such excess shares shall not have any voting or dividend rights; (v) permit SEACOR Marine to redeem any such excess shares; and (vi) permit the Board of Directors to make such reasonable determinations as may be necessary to ascertain such ownership and implement such limitations. In addition, SEACOR Marine’s Third Amended and Restated By-Laws limit the number of non-U.S. citizens that may serve as directors and restrict any non-U.S. citizen from, among other things, holding certain specified senior officer positions. For more information, see SEACOR Marine’s Third Amended and Restated Certificate of Incorporation and Third Amended and Restated By-Laws, which are filed as exhibits to this Annual Report on Form 10-K. The Maritime Labour Convention, 2006 (the “MLC”) establishes comprehensive minimum requirements for working conditions of seafarers including, among other things, conditions of employment, hours of work and rest, grievance and complaints procedures, accommodations, recreational facilities, food and catering, health protection, medical care, welfare, and social security protection. The MLC defines seafarer to include all persons engaged in work on a vessel in addition to the vessel’s crew. Under this MLC definition, the Company may be responsible for proving that customer and contractor personnel aboard its vessels have contracts of employment that comply with the MLC requirements. The Company could also be potentially responsible for salaries and/or benefits of third parties that may board one of its vessels. The MLC requires certain vessels that engage in international trade to maintain a valid Maritime Labour Certificate issued by their flag administration. Although the U.S. is not a party to the MLC, U.S.-flag vessels operating internationally must comply with the MLC when visiting a port in a country that is a party to the MLC. As part of its safety management system (“SMS”), the Company maintains a fleetwide plan designed to comply with the MLC to the extent applicable to its vessels. The hull and machinery of most commercial vessels are classed by an international classification society authorized by its country of registry and subject to survey and inspection by shipping regulatory bodies. The international classification society certifies that a vessel is maintained in accordance with the applicable rules and regulations of the vessel’s country of registry and SOLAS. Certain of the Company's vessels are subject to the periodic inspection, survey, drydocking and maintenance requirements of the USCG, the American Bureau of Shipping (“ABS”) and other marine classification societies. Under provisions of the Merchant Marine Act of 1936 (“Merchant Marine Act”) and Chapter 563 of Title 46 of the U.S. Code, the Company’s U.S.-flag vessels are subject to requisition, charter or purchase by the U.S. government under certain terms and conditions during a national emergency as described further in “Item 1A. Risk Factors” under the heading “Under certain circumstances, the Company’s vessels are subject to requisition for ownership or use by governmental agencies” of this Annual Report on Form 10-K. Vessels registered under other flag states may also be subject to requisition or purchase in accordance with applicable local law. A wide range of domestic governmental agencies, including the USCG, the EPA, the U.S. Department of Transportation’s Office of Pipeline Safety, the BSEE and certain individual states, regulate vessels and other structures in accordance with the requirements of the Oil Pollution Act of 1990 (“OPA 90”) or analogous state law. There is currently little uniformity among the regulations issued by these agencies, which increases the Company’s compliance costs and risk of non-compliance. The International Safety Management Code (“ISM Code”), adopted by the International Maritime Organization (the “IMO”) as an amendment to SOLAS, provides international standards for the safe management and operation of ships and for the prevention of marine pollution from ships. The U.S. enforces the ISM Code for all U.S.-flag vessels and those foreign-flag vessels that call at U.S. ports. All of the Company’s vessels that are 500 or more gross tons are certified as required under the standards set forth in the ISM Code’s safety and pollution protocols. The Company also voluntarily complies with these protocols for some vessels that are under the mandatory 500-gross ton threshold and many of the Company’s customers contractually require compliance with these protocols regardless of the gross tonnage of the vessel. Under the ISM Code, vessel operators are required to develop an extensive SMS applicable to the vessel and shoreside personnel that includes, among other things, the adoption of a written system of safety and environmental protection policies setting forth instructions and procedures for operating their vessels subject to the ISM Code and describing procedures for responding to emergencies. The ISM Code also requires a Document of Compliance to be obtained for the vessel manager and a Safety Management Certificate to be obtained for each vessel subject to the ISM Code that it operates or manages. The Company believes that it has complied with these requirements in all material respects. Noncompliance with the ISM Code and other IMO regulations may subject the shipowner or charterer to increased liability, may lead to decreases in available insurance coverage for affected vessels, may cause the loss of customers, and may result in the denial of access to, or detention in, some ports. For example, the USCG authorities have indicated that vessels not in compliance with the ISM Code will be prohibited from utilizing U.S. ports. 7 Regulatory Compliance OPA 90 establishes a regulatory and liability regime for the protection of the environment from oil spills. OPA 90 applies to owners and operators of facilities operating near navigable waters of the U.S., and owners, operators and bareboat charterers of vessels operating in U.S. waters, which include the navigable waters of the U.S. and the 200-mile exclusive economic zone around the U.S. (the “EEZ”). For purposes of its liability limits and financial responsibility and response planning requirements, OPA 90 differentiates between tank vessels (such as chemical and petroleum product vessels and liquid tank barges) and “other vessels” (such as the Company’s offshore support vessels). Under OPA 90, owners and operators of regulated facilities and owners and operators or bareboat charterers of vessels are “responsible parties” and may be jointly, severally and strictly liable for removal costs and damages arising from facility and vessel oil spills or threatened spills up to certain limits of liability as discussed below. Damages are defined broadly to include: (i) injury to natural resources and the costs of remediation thereof; (ii) injury to, or economic losses resulting from, the destruction of real and personal property; (iii) net loss by various governmental bodies of taxes, royalties, rents, fees or profits; (iv) lost profits or impairment of earning capacity due to property or natural resources damage; (v) net costs of providing increased or additional public services necessitated by a spill response, such as protection from fire or other hazards or taking additional safety precautions; and (vi) loss of subsistence use of available natural resources. OPA 90 limits liability for responsible parties for non-tank vessels, such as the Company’s, to the greater of $1,300 per gross ton or $1,076,000. These liability limits do not apply (a) if an incident is caused by the responsible party’s violation (or the violation of a person acting pursuant to a contract with the responsible party) of federal safety, construction or operating regulations or by the responsible party’s gross negligence or willful misconduct, (b) if the responsible party fails or refuses to report the incident or to provide reasonable cooperation and assistance in connection with oil removal activities as required by a responsible official or (c) if the responsible party fails or refuses to comply with an order issued under OPA 90. OPA 90 requires vessel owners and operators to establish and maintain with the USCG evidence of insurance or qualification as a self-insurer or other evidence of financial responsibility sufficient to meet their potential liabilities under OPA 90. In recent years, the Company has satisfied USCG regulations by providing evidence of financial responsibility demonstrated by commercial insurance and self-insurance. OPA 90 regulations also implement the financial responsibility requirements of the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), which imposes liability for any discharge of hazardous substances, similar to OPA 90, and provides compensation for cleanup, removal and natural resource damages. Liability per vessel under CERCLA is limited to the greater of $300 per gross ton or $5.0 million, unless the incident is caused by gross negligence, willful misconduct, or a violation of certain regulations, in which case liability is unlimited. Under the USCG regulations, owners and operators of non-tank vessels are required to prepare response plans. The Company expects its current pollution liability insurance to cover spill removal costs and damage, subject to coverage deductibles and limitations, including a cap of $1.0 billion. The Company’s business, financial position, results of operations, cash flows or prospects could be material adversely affected if the Company incurs spill liability under circumstances in which the Company’s insurance does not provide coverage, the Company’s underwriters fail or refuse to pay a covered claim, or the loss exceeds the Company’s coverage limitations. MARPOL is the main international convention covering prevention of marine pollution by vessels from operational or accidental discharges. It is implemented in the U.S. pursuant to the Act to Prevent Pollution from Ships. Since the 1990s, the Department of Justice (“DOJ”) has been aggressively enforcing U.S. criminal laws against vessel owners, operators, managers, crew members, shore side personnel, and corporate officers related to violations of MARPOL. Violations have related to pollution prevention devices, such as the oily-water separator, and include falsifying records, obstructing justice, and making false statements. In certain cases, responsible shipboard officers and shoreside officials have been sentenced to prison. In addition, the DOJ has required most defendants to implement a comprehensive environmental compliance plan (“ECP”) or risk losing the ability to operate in U.S. waters. If the Company is subjected to a DOJ prosecution, it could suffer material adverse effects, including substantial criminal penalties and defense costs, reputational damages and costs associated with the implementation of an ECP. The Clean Water Act (“CWA”) prohibits the discharge of “pollutants” into the navigable waters of the U.S. The CWA also prohibits the discharge of oil or hazardous substances into navigable waters of the U.S. and the EEZ around the U.S. and imposes civil and criminal penalties for unauthorized discharges, thereby exposing the Company to potential liability that is in addition to its exposure arising under OPA 90 and CERCLA. The CWA also imposes liability for removal and cleanup costs. 8 The CWA also established the National Pollutant Discharge Elimination System (“NPDES”) permitting program, which governs discharges of pollutants into navigable waters of the U.S. Pursuant to the NPDES permitting program, the EPA has issued Vessel General Permits covering discharges incidental to normal vessel operations. The EPA issued the 2013 Vessel General Permit (“2013 VGP”) with an initial five-year term. In light of the legislation described below, the 2013 VGP continues to apply to the Company’s U.S.-flag and foreign-flag commercial vessels that are at least 79 feet in length and operate within the three-mile territorial sea of the U.S. The 2013 VGP requires vessel owners and operators to adhere to “best management practices” to manage the covered discharges that occur normally in the operation of a vessel, including ballast water, and implements various training, inspection, monitoring, record keeping, and reporting requirements, as well as corrective actions upon identification of deficiencies. The Company has filed a Notice of Intent to be covered by the 2013 VGP for each of its ships that operate in U.S. waters. On December 4, 2018, the U.S. Congress enacted the Vessel Incidental Discharge Act (“VIDA”), establishing a new framework for the regulation of discharges incidental to the normal operations of vessels. In October of 2020, the EPA published proposed performance standards for vessel incidental discharges, and in October 2023 the EPA supplemented the proposed rulemaking in response to public comments, providing additional USCG data and supplemental regulatory options being considered by the EPA for discharge from ballast tanks, hulls and niche areas, and graywater systems. The final rule is expected to be published in the Federal Register in the fall of 2024, which will be followed by a USCG rulemaking process to issue enforcement regulations, with a deadline set by the VIDA of two years after the EPA’s final rule. VIDA extends the 2013 VGP’s provisions, leaving them in effect until new regulations are final and enforceable. Non-military, non-recreational vessels greater than 79 feet in length must continue to comply with the requirements of the 2013 VGP, including submission of annual reports. The Company believes it is premature to predict what additional costs it may incur to comply with any such new regulations and performance standards. Many countries have ratified and apply the liability scheme adopted by the IMO and set out in the International Convention on Civil Liability for Oil Pollution Damage of 1969 (the “1969 Convention”). Some of these countries have also adopted the 1992 Protocol to the 1969 Convention (the “1992 Protocol”). Under both the 1969 Convention and the 1992 Protocol, a vessel’s registered owner is strictly liable for pollution damage caused in the territorial waters of a contracting state by discharge of persistent oil from ships carrying oil in bulk as cargo, subject to certain defenses. These conventions also limit the liability of the shipowner under certain circumstances, provided the discharge was not caused by the shipowner’s actual fault or intentional or reckless misconduct. Vessels trading to countries that are parties to these conventions must provide evidence of insurance covering the liability of the owner. The Company believes that its Protection and Indemnity insurance should cover any liability under these conventions, subject to applicable policy deductibles, exclusions and limitations. The U.S. is not a party to the 1969 Convention or the 1992 Protocol, and thus OPA 90, CERCLA, CWA and other federal and state laws apply in the U.S. as discussed above. In other jurisdictions where the 1969 Convention has not been adopted, various local legislative and regulatory schemes or common law govern, and liability is imposed either on the basis of fault or in a manner similar to the 1969 Convention. The International Convention on Civil Liability for Bunker Oil Pollution Damage, 2001, was adopted to ensure that adequate, prompt and effective compensation is available to persons who suffer damage caused by spills of oil when used as fuel by vessels. The convention applies to damage caused to the territory, including the territorial sea, and in the EEZs, of the countries that are party to it. Although the U.S. has not ratified this convention, U.S.-flag vessels operating internationally are subject to it when they sail within the territorial waters of those countries that have implemented its provisions. The Company believes that its vessels comply with these requirements. The U.S. National Invasive Species Act (“NISA”) was enacted in 1996 in response to growing reports of harmful organisms being released into U.S. waters through ballast water received in foreign ports. The USCG adopted regulations under NISA that impose mandatory ballast water management practices for all vessels equipped with ballast water tanks entering U.S. waters. All new vessels constructed on or after December 1, 2013, regardless of ballast water capacity, must comply with these requirements on delivery from the shipyard absent an extension from the USCG. For non-exempt vessels, ballast water treatment equipment may be required to be used on the vessel. Some U.S. states have enacted legislation or regulations to address the introduction of invasive species through ballast water and hull cleaning management, and permitting requirements, which in many cases have also become part of the state’s 2013 VGP certification. Other states may proceed with the enactment of similar requirements that could increase the Company’s costs of operating in state waters. The Company believes that all of its vessels maintain a ballast water management plan compliant with applicable regulations. The IMO ratified the International Convention for the Control and Management of Ships’ Ballast Water and Sediments, otherwise known as the Ballast Water Management Convention (the “BWM Convention”), effective September 8, 2017. Under the BWM Convention, all ships engaged in international voyages are required to manage their ballast water and sediments under a ship- specific ballast water management plan. The U.S. is not a party to the BWM Convention, but U.S. flagged vessels that undertake international voyages may have to install a USCG/EPA approved ballast water treatment system (“BWTS”) or use one of the other management options under the USCG/EPA ballast water management rules and the BWM Convention to achieve compliance. The Company installs BWTS on its vessels as required by the USCG/EPA and BWM Convention. 9 The Endangered Species Act, related regulations and comparable state laws protect species threatened with possible extinction. Protection may include restrictions on the speed of vessels in certain ocean waters and may require the Company to change the routes of vessels during particular periods. The Clean Air Act (as amended, the “CAA”) requires the EPA to promulgate standards applicable to emissions of various air contaminants. The CAA also requires states to submit State Implementation Plans (“SIPs”), which are designed to attain national health- based air quality standards throughout the U.S., including major metropolitan and industrial areas. Several SIPs regulate emissions resulting from vessel loading and unloading operations by requiring the installation of vapor control equipment. The EPA and some U.S. states have each proposed more stringent regulations of air emissions from propulsion and auxiliary engines on oceangoing vessels. MARPOL also addresses air emissions, including emissions of sulfur and nitrous oxide (“NOx”), from vessels, including a requirement to use low sulfur fuels worldwide in both auxiliary and main propulsion diesel engines on vessels. Since January 1, 2020, vessels worldwide have been required to use fuel with a sulfur content no greater than 0.5%, which is a reduction from the prior limit of 3.5%. MARPOL also imposes NOx emissions standards on installed marine diesel engines of over 130 kW output power other than those used solely for emergency purposes irrespective of the tonnage of the vessel into which such an engine is installed. The actual NOx limit is determined by a variety of factors, including the vessel’s construction date, rated engine speed, and operating area. More stringent sulfur and NOx requirements apply in certain designated Emission Control Areas (“ECAs”). There are currently four ECAs worldwide: the Baltic Sea ECA, North Sea ECA, North American ECA, and U.S. Caribbean ECA. As of January 1, 2015, vessels operating in an ECA must burn fuel with a sulfur content no greater than 0.1%. Further, marine diesel engines on vessels constructed on or after January 1, 2016 that are operated in an ECA must meet the stringent NOx standards described above. The Company’s operations occasionally generate and require the transportation, treatment and disposal of both hazardous and non-hazardous solid wastes that are subject in the U.S. to the requirements of the Resource Conservation and Recovery Act (“RCRA”) or comparable state, local or foreign requirements. From time to time the Company arranges for the disposal of hazardous waste or hazardous substances at offsite disposal facilities. As a general matter, with certain exceptions, vessel owners and operators are required to determine if their wastes are hazardous, obtain a generator identification number, comply with certain standards for the proper management of hazardous wastes, and use hazardous waste manifests for shipments to disposal facilities. Moreover, vessel owners and operators may be subject to more stringent state hazardous waste requirements. If such materials are improperly disposed of by third parties with which the Company contracts, the Company could potentially be held liable for cleanup costs under applicable laws. MARPOL also governs the discharge of garbage from ships. MARPOL defines certain sea areas, such as the “wider Caribbean region” as “special areas” requiring a higher level of protection than other areas of the sea. Applicable MARPOL regulations provide for strict garbage management procedures and documentation requirements for all vessels and fixed and floating platforms. These regulations impose a general prohibition on the discharge of all garbage unless the discharge is expressly provided for under the regulations. The regulations have greatly reduced the amount of garbage that the Company’s vessels are allowed to dispose of at sea. Various international conventions and federal, state and local laws and regulations have been considered or implemented to address the environmental effects of emissions of greenhouse gases, such as carbon dioxide and methane. At United Nations climate change conferences over the past few decades, various countries have agreed to specific international accords or protocols to establish limitations on greenhouse gas emissions. In December 1997, the Kyoto Protocol was adopted pursuant to which member parties agreed to implement national programs to reduce emissions of greenhouse gases. At the 2015 United Nations climate change conference in Paris, the U.S. and various other countries adopted the Paris Agreement, which seeks to reduce emissions in an effort to slow global warming. At the 2023 COP28 United Nations climate summit in Dubai, the U.S. and nearly 200 other countries agreed to transition away from using fossil fuels in energy systems. None of these U.N. accords specifically mention shipping. The IMO has announced its intention to develop limits on greenhouse gases from international shipping and is working on proposed mandatory technical and operational measures to achieve these limits. The first step toward this goal occurred in October 2016, when the IMO adopted a system for collecting data on ships’ fuel-oil consumption, which will be mandatory and apply globally. In 2020, the IMO proposed amendments to MARPOL that would require vessels to combine a technical and an operational approach to reduce their carbon intensity. The measures are aimed at reducing carbon intensity of international shipping by 40% by 2030, compared to 2008. The IMO’s Marine Environment Protection Committee adopted a revised strategy to reduce greenhouse gas emissions and has set a target to reach net-zero GHG emissions from shipping by or around 2050. For operation within the European Union (“E.U.”), the Company’s vessels need to meet the E.U. Ship Recycling Regulation (“E.U. SRR”) that requires survey and record of Inventory of Hazardous Materials (“IHM”). The Company’s fleet is being impacted by changes to MARPOL and the International Code for the Construction and Equipment of Ships carrying Dangerous Chemicals in Bulk (“IBC Code”) which sets out the international standards for the safe carriage, in bulk by sea, of dangerous chemicals and noxious liquid substances (“NLS”). These changes limit the number of dangerous chemicals and NLS cargoes that the Company’s vessels can carry and impose additional requirements that could, in certain instances, functionally preclude their carriage. Any future adoption of climate control treaties, legislation or other regulatory measures by the United Nations, IMO, the E.U., U.S. or other countries where the Company operates that restrict emissions of greenhouse gases could result in financial and operational impacts on the Company’s business (including potential capital expenditures to reduce such emissions). 10 The Company manages exposure to losses from the above-described treaties, laws and regulations through its development of appropriate risk management programs, including compliance programs, safety management systems and insurance programs. Although the Company believes these programs mitigate its legal risk, there can be no assurance that these programs will be able to prevent all infractions, nor can the Company provide assurances that future regulations or requirements or any discharge or emission of pollutants by the Company will not have a material adverse effect on its business, financial position, results of operations, cash flows or prospects. In addition to the above description of U.S. and E.U. laws and international conventions, the Company’s foreign operations are subject from time to time to similar laws of other countries. Security The USCG, the IMO, states and local ports continue to adopt heightened security procedures related to ports and vessels. To implement certain portions of the U.S. Maritime Transportation Security Act of 2002 (“MTSA”), the USCG issued regulations in 2003 requiring the implementation of certain security requirements aboard vessels operating in waters subject to the jurisdiction of the U.S. Similarly, in December 2002, the IMO adopted amendments to SOLAS, known as the ISPS Code, creating a new chapter dealing specifically with maritime security. The chapter imposes various detailed security obligations on vessels and port authorities. Included in the various requirements under MTSA and/or the ISPS Code are the following: • • • • • onboard installation of automatic information systems to enhance vessel-to-vessel and vessel-to-shore communications; onboard installation of ship security alert systems; the development of vessel security plans and facility security plans, as applicable; the implementation of a Transportation Worker Identification Credential program in the U.S.; and compliance with flag state security certification requirements. The USCG regulations, which are intended to align with international maritime security standards, generally deem foreign-flag vessels to be in compliance with MTSA vessel security measures provided such vessels have onboard a valid International Ship Security Certificate that attests to the vessel’s compliance with SOLAS security requirements and the ISPS Code. However, U.S.-flag vessels that are engaged in international trade must comply with all of the security measures required by MTSA, as well as SOLAS and the ISPS Code. In response to these security programs, the Company has implemented red flag security plans and other procedures designed to address applicable security standards. Industry Hazards and Insurance Vessel operations involve inherent risks associated with carrying large volumes of cargo and rendering services in a marine environment. Hazards include adverse weather conditions, collisions, fire and mechanical failures, which may result in death or injury to personnel, damage to equipment, loss of operating revenues, contamination of cargo, pollution and other environmental damages and increased costs. The Company maintains hull, liability and war risk, general liability, workers compensation and other customary insurance subject to various deductions, exclusions and coverage caps. The Company also conducts training, drills and safety awareness programs to promote a safe working environment and minimize and respond to hazards. See “Item 1A. Risk Factors – The Company is subject to hazards inherent in the operation of offshore support and related vessels and has experienced accidents that have resulted in the loss of life, disrupted operations and caused reputational harm.” Employees and Human Capital Management The Company’s sustainability council (the “Sustainability Council”), established on September 17, 2020, is mandated to oversee the Company’s enhanced environmental, social and governance (“ESG”) program. The Sustainability Council is an internal committee led by SEACOR Marine’s Chief Executive Officer with membership made up of senior executives, operational heads, and safety and health, compliance, and human resources professionals. The Sustainability Council that reports to the Nominating and Corporate Governance Committee of the Board of Directors. The Sustainability Council collaborates and drives initiatives on all matters related to sustainability, including, but not limited to environmental protection, clean energy technology, social responsibility, employee, lender, contractor and community engagement, health and safety, and community empowerment. Together with the Board of Directors, the Sustainability Council helps establish sustainability goals and integrate them into strategic and tactical business activities across the Company to contribute to risk management and long-term value for all stakeholders. 11 The Company periodically publishes a Sustainability Report, offering in-depth insights into the Company’s sustainability efforts and ESG practices. Additionally, the Company’s website features a dedicated section specifically focusing on its ESG efforts and its sustainable and responsible business practices. As part of the Company’s ESG efforts and with the assistance of the Sustainability Council, the Company’s Chief Executive Officer has the primary responsibility for developing, managing, and executing the Company’s human capital strategy. As of December 31, 2023, the Company employed 1,256 individuals directly and indirectly (through crewing or manning agreements), none of whom are members of a union under the terms of an ongoing agreement. Management considers relations with its employees to be good. The Company believes that its success is driven by its employees, and its human capital strategy focuses on the following key areas: Health and Safety: The health and safety of the Company’s employees is its highest priority. The Company’s health and safety programs, namely its SMS, are implemented to comply with applicable regulations and follow global standards, as well as address the specific hazards of the Company’s various work environments. The Company continues to implement enhanced health and safety protocols throughout its operations, including through the provision of personal protective equipment for offshore operation and installation of hydroxyl generators in vessel heating, ventilation, and air conditioning systems primarily to destroy pathogens, viruses and bacteria on surfaces and in the air. For the Company’s onshore employees, the Company has enhanced remote working capabilities as well as other arrangements. The Company regularly conducts management reviews, audits, and inspections onboard its vessels and shore side locations to ensure compliance with applicable regulations, policies, and procedures. Among other periodic audits by flag states and customers, the Company is also audited annually by an independent classification society to confirm compliance with applicable regulations and standards. The Company utilizes several metrics to assess the performance of its health and safety policies, procedures, and initiatives, including pollution incidents, lost time incidents, medical incidents, and fatalities. In fiscal year 2023, the Company worked over 5.9 million man-hours across its global businesses, and recorded zero pollution incidents, zero medical incidents, three lost time incidents and a total recordable incident rate of 0.100. Diversity, Equity and Inclusion: The Company recognizes the value of diversity, equity and inclusion within its organization and strives to ensure that its workplace reflects the diverse communities in which it operates in order to promote collaboration, innovation, creativity and belonging. The Sustainability Council has been mandated by the Nominating and Corporate Governance Committee to develop strategies to promote diversity, equity and inclusion in the workplace and oversees the Company’s Diversity, Equity and Inclusion Committee, which is responsible for developing policies and practices to recruit, support, promote and retain staff with diverse backgrounds, experiences and attributes. The Company is proud of its diverse workforce and cross-cultural competences and, as of December 31, 2023, employed individuals from over 38 countries. The Company further recognizes that the maritime industry has traditionally been male dominated, and as a result, the Company is seeking to increase the representation of females by developing practical and innovative strategies. As of December 31, 2023, 33% of SEACOR Marine’s onshore workforce was female, while only a small fraction of its at sea workforce were female seafarers. SEACOR Marine is committed to continuing to recruit and employ qualified candidates regardless of their gender or cultural background or identity. Training and Talent Development: The Company is committed to the education of its employees and has committed to provide its employees with a variety of learning opportunities, including, but not limited to, leadership training, technical skill development, soft skills development, workplace conduct guidance, and health, safety and security training. The Sustainability Council works collaboratively with SEACOR Marine’s human resources department to continually enhance and promote its training programs to attract new talent as well as develop and retain talent within the organization. Employee Benefits: The Company believes in the importance of offering its employees competitive salaries and wages, together with comprehensive insurance options. The Company recognizes the importance of comprehensive benefits, including medical, prescription drug, vision, dental, life, disability and flexible spending, employees and their family members are provided with tools and resources to assist in adopting and maintaining a healthy lifestyle. The Company pays the cost of basic life insurance, accidental death and dismemberment insurance, short-term and long-term disability for its employees. Additionally, employees may purchase supplemental life, dependent life, and additional long-term disability insurance. Other valuable benefits provided by the Company include life and travel assistance programs, will preparation and a 401(k) plan. 12 ITEM 1A.

The market for the Company’s offshore support services is impacted by the comparative price for exploring, developing, and producing oil and natural gas and by the corresponding supply and demand for oil and natural gas, both globally and regionally. The prices of these commodities are subject to significant volatility. Among other factors, the increased supply of oil and natural gas from the development of unconventional oil and natural gas supply sources, particularly shale, and technologies to improve recovery from current sources have caused volatility in the price of oil and natural gas as well as a reduction of demand and prices charged for offshore support services globally. The increased use of electric cars and the development of alternative sources of energy to hydrocarbons, such as solar and wind power and other developing technology, as well as increasing regulations on greenhouse gas emissions and actions taken and expected to be taken by companies, governments and investors to reduce dependence on hydrocarbon-based fuels, are widely expected to further diminish the demand for oil and natural gas in the coming years. Other factors that influence the supply and demand and the relative price of oil and natural gas include operational issues, natural disasters, weather, political instability, conflicts, civil unrest, the worldwide economic, political and military environment, acts of terrorism, foreign exchange rates, economic conditions and actions by major hydrocarbon-producing countries, as well as sanctions on such countries that prohibit the sale of these commodities. The price of oil and natural gas and the relative cost to extract, proximity to market and political imperatives of countries with offshore deposits affect the willingness to commit investment for contract drilling rigs and offshore support vessels used for offshore exploration, field development and production activities, which in turn affects the Company’s results of operations. Prolonged periods of low oil and natural gas prices or rising costs result in lower demand for the Company’s services and can give rise to impairments of the Company’s assets. The Company’s operations depend on the level of spending by oil and natural gas companies for exploration, development and production, maintenance and decommissioning activities. Both short-term and long-term trends in oil and natural gas prices affect these activity levels. Oil and natural gas prices, as well as the level of drilling, exploration and production activity, have been highly volatile over the past few years and are expected to continue to be volatile for the foreseeable future. The volatility of the energy markets generally makes it extremely difficult to predict future oil and natural gas price movements over the long term. For example, oil prices were as high as $107 per barrel during 2014, followed by a near ten-year low of $26 per barrel in February 2016, and then back to $76 per barrel in October 2018. The West Texas Intermediate (“WTI”) front month oil prices experienced unprecedented volatility during 2020 as a result of the COVID-19 pandemic and the related impact on the global economy, including going negative for a short period of time. Oil prices have recovered since the lows hit at the beginning of the COVID-19 pandemic and in June 2022 hit a multi-year high of $122 per barrel primarily as a result of the conflict between Russia and Ukraine as well as the related economic sanctions imposed on Russia by the U.S., Canada and European countries. During 2023, WTI oil prices hit a low of $67 per barrel and a high of $94 per barrel, ending the year in the $72 per barrel range. Declines in oil prices are primarily caused by, among other things, an excess of supply of crude oil in relation to demand. Since developing offshore oil fields, particularly in deep waters, is one of the most capital intensive sources of hydrocarbons and providing transportation and logistics services to these markets is the largest component of the Company’s business, the Company is particularly exposed to depressed oil and natural gas prices that last for some period of time. When the Company’s customers experience low commodity prices or come to believe that they will be low in the future, they generally reduce their capital spending for offshore drilling, exploration and field development. The significant decrease in oil and natural gas prices experienced in 2020 as a result of the COVID-19 pandemic and the related effects of the pandemic on the global economy caused a reduction in many of the Company’s customers’ exploratory, drilling, completion and other production activities and, as a result, reduced related spending on the Company’s services. While spending on the Company’s services has steadily improved, the Company’s overall fleet utilization for the years ended December 31, 2023, 2022 and 2021, was 75%, 75% and 66%, respectively. The prolonged reduction in the overall level of exploration and development activities has materially and adversely affected the Company by negatively impacting its fleet utilization, which in turn has negatively affected its revenues, cash flows, profitability and the fair market value of the Company’s vessels. It could also affect the collectability of the Company’s receivables and its ability to retain skilled personnel. Periods of low activity intensify price competition in the industry, which erodes operating margins, and can lead to the Company’s vessels being idle for long periods of time and, in turn, could lead to significant expenses upon reactivation. Demand for many of the Company’s services is impacted by the level of activity in the offshore oil and natural gas exploration, development and production industry. The level of offshore oil and natural gas exploration, development and production activity has historically been volatile. This volatility is likely to continue. The level of activity is subject to large fluctuations in response to relatively minor changes in a variety of factors that are beyond the Company’s control, including: • • the worldwide economic environment, trends in international trade or other economic trends, including recessions and the level of activity in energy-consuming markets; prevailing oil and natural gas prices and expectations about future prices and price volatility; 15 • • assessments of offshore drilling prospects compared with land-based opportunities; the cost of exploring for, producing and delivering oil and natural gas offshore and the relative cost of, and success in, doing so on land, including fracking and other technologies that make it more economical to produce oil from non- traditional sources; • consolidation of oil and natural gas and oil service companies operating offshore; • worldwide supply and demand for energy, petroleum products and chemical products; • • • • • • • availability and rate of discovery of new oil and natural gas reserves in offshore areas; federal, state, local and international political and economic conditions, and policies including cabotage and local content laws; technological advancements affecting exploration, development, energy production and consumption; the ability or willingness of the Organization of Petroleum Exporting Countries (“OPEC”) to set and maintain production levels and pricing; the level of oil and natural gas production by non-OPEC countries; international sanctions on oil producing countries including certain sanctions against Iran, Russia and Venezuela and the acceptance of oil produced by such countries; terrorism, civil unrest and the worldwide political and military environment, including uncertainty or instability resulting from an escalation or additional outbreak of armed hostilities involving significant oil producing regions such as the Middle East, Russia and Venezuela as well as other geographic areas, including the U.S.; • weather conditions and catastrophic events; • • • • environmental regulation and, more generally, the energy transition to non-hydrocarbon sources; regulation of drilling activities and the availability of drilling permits and concessions; the ability of oil and natural gas companies to generate or otherwise obtain funds for capital projects; and increase in the use and exploitation of renewable energy and the development of alternative fuel or energy sources. The prolonged material downturn in oil and natural gas prices until the recent recovery experienced in 2021 caused a substantial decline in expenditures for exploration, development and production activity, which resulted in a decline in demand and lower rates for the Company’s offshore energy support services and, in turn, lower utilization levels. Although activity levels and day rates have recovered somewhat over the past few years, continued under-investment by our customers or a new decrease in activity could once again reduce the Company’s day rates and its utilization, which would in turn have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. In addition, increases in commodity demand and prices will not necessarily result in an immediate increase in offshore drilling activity since project development lead and planning times, reserve replacement needs, expectations of future commodity demand, energy transition, customer capital discipline, prices and supply of available competing vessels all combine to affect demand for the Company’s vessels. The Company operates in four primary regions: the U.S., primarily the U.S. Gulf of Mexico; Africa and Europe; the Middle East and Asia; and Latin America, primarily in Mexico and Guyana. The volume of work contributed by each region changes periodically due to a number of factors including how active each region is, how many vessels are working in each region and the changing political, economic or regulatory landscape of the applicable region. For instance, for the years ended December 31, 2023, 2022, and 2021, approximately 21%, 28% and 12%, respectively, of the Company’s operating revenues were earned in the U.S. The Company has some ability to shift the location of its assets between regions depending upon local regulation and cost of doing business, among many other factors, and, while it has repositioned some assets from less active regions to other regions and may continue to do so in the future, such efforts may not be sufficient to counter any changes in demand in any particular region. The Company’s business operations and workforce face risks related to public health emergencies, which could significantly disrupt the Company’s operations. Public health emergencies, including pandemics, epidemics and other outbreaks, pose significant risks to our business through their effect on the economy and subsequent effect on supply and demand for our services, labor shortages, and operational processes, among other factors. 16 Additionally, an outbreak of contagious disease on any of the Company’s vessels may result in the vessel, or some or all of the vessel crew, being quarantined or unable to work, which would hinder the vessel’s ability to generate revenue and the crew’s ability to man any substitute vessel. The Company may also experience challenges in connection with offshore crew changes due to health and travel restrictions and precautionary measures related to a public health emergency. Any such restrictions or precautionary measures may curtail travel or impact the delivery or mobilization of vessels to and from certain countries, or geographic regions, or the ability to crew vessels appropriately. The risks posed by a public health emergency could not only materially adversely affect the demand for the Company’s services but could also impact the Company’s ability to provide such services, either of which could have a material adverse effect on the Company’s business. Adverse effects of a public health emergency could exacerbate many of the other risks set forth in this “Risk Factors” section and the Company’s other SEC filings, such as those relating to the Company’s financial performance and debt obligations and ability to crew its vessels. Restrictions imposed by the terms of the Company’s existing credit facilities or future indebtedness it may incur can limit the Company’s operating and financial flexibility. In addition, there can be no assurance that the Company will meet the requirements of its financial covenants on an ongoing basis or that if it should fail to meet such covenants in the future, the lender under the relevant credit agreement will agree to waivers or amendments with respect thereto. The Company’s existing credit facilities impose, and its future credit facilities may impose, restrictions, such as negative covenants and maintenance of financial ratio covenants, which may limit the Company’s operating and financial flexibility. Negative covenants such as limitations on the incurrence of additional indebtedness or liens may affect the Company’s ability to incur additional debt if needed, while asset sale covenants could affect its ability to sell assets to generate liquidity and properly manage its fleet size. Requirements to maintain a minimum level of liquidity could also affect cash available for working capital, capital expenditures, debt service and general corporate purposes. For instance, the 2023 SMFH Credit Facility (as defined below) contains covenants limiting the ability of the Company and its subsidiaries to incur additional indebtedness or liens (subject to important exceptions) and also requires the Company to maintain a minimum of Cash and Cash Equivalents equal to the higher of $20.0 million and 7.5% of Net Interest- Bearing Debt (as each are defined in the 2023 SMFH Credit Facility) (see “Note 6. Long-Term Debt” in the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K). While the Company was in compliance with all such covenants as of December 31, 2023, the Company’s ability to maintain compliance with these financial ratio covenants may be affected by general economic conditions or other events beyond the Company’s control and no assurance can be given that such ratios will be met in the future. If the Company is unable to meet such ratios or is otherwise unable to comply with covenants in these facilities, it may be unable to reach agreements with the lenders under such credit facilities for waivers and/or amendments to the applicable covenants. Failure to comply with these restrictions could result in the lenders accelerating all amounts due under the credit facility and potentially trigger a cross-default or acceleration of the Company’s other credit facilities. There are risks associated with the Company’s indebtedness. As of December 31, 2023, the Company has $353.0 million of outstanding indebtedness, including $90.0 million in aggregate principal amount of the Company’s 8.0% / 9.5% Senior PIK Toggle Notes due 2026 (the “Guaranteed Notes”), $35.0 million in aggregate principal amount of SEACOR Marine’s 4.25% Convertible Senior Notes due 2026 (the “New Convertible Notes”) and obligations under credit facilities secured by mortgages on various vessels. These obligations include: (i) $119.0 million of outstanding indebtedness under the loan facility entered into by SEACOR Marine Foreign Holdings Inc. (“SMFH”), a wholly owned subsidiary of the Company, on September 8, 2023 (the “2023 SMFH Credit Facility”); (ii) $14.2 million of outstanding indebtedness under the loan facility entered into by Sea-Cat Crewzer III LLC (“Sea-Cat Crewzer III”), a wholly owned subsidiary of the Company, on April 21, 2016 (the “Sea-Cat Crewzer III Loan Facility”); (iii) $68.6 million of outstanding indebtedness under the deferred purchase agreements entered into by eight vessel owning subsidiaries (the “SEACOR Delta SPVs”), each wholly owned by the Company (the “SEACOR Delta Shipyard Financing”); and (iv) $26.2 million of outstanding indebtedness under the loan facility entered into by three vessel owning subsidiaries (the “SEACOR Alpine Borrowers”), each wholly owned by the Company, on June 16, 2023 (the “SEACOR Alpine Credit Facility”). As of December 31, 2023, $68.6 million of the Company’s outstanding indebtedness bore interest at a floating rate, with the remainder bearing interest at fixed rates. The Company’s ability to meet its debt service obligations and refinance its current indebtedness, as well as any future debt that it may incur, will depend upon its ability to generate cash in the future from operations, financings or asset sales, which are subject to general economic conditions, the Company’s results of operations, industry cycles, seasonality, the interest rate environment and its effect on the Company’s floating rate debt, the general state of the capital markets at the time it seeks to refinance its debt, financial, business and other factors, some of which may be beyond the Company’s control. If the Company cannot repay or refinance its debt as it becomes due, the Company may be forced to sell assets or take other disadvantageous actions, including undertaking alternative financing plans, which may have onerous terms or may be unavailable, dedicating an unsustainable level of the Company’s cash flow from operations to the payment of principal and interest on its indebtedness and/or reducing the amount of liquidity available for working capital, capital expenditures and general corporate purposes. The Company’s failure to pay or refinance its current or future debt under a credit facility when it becomes due could potentially trigger a cross-default or acceleration of the Company’s other credit facilities. The Company’s obligations to repay indebtedness and comply with restrictive and/or financial maintenance covenants could also impair its ability to rapidly respond to changes in its business or industry and withstand competitive pressures. For additional information, see 17 “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” of this Annual Report on Form 10-K. The Company’s overall debt level and/or market conditions could limit its ability to issue additional debt in amounts and/or on terms that it considers reasonable. Unconventional crude oil and natural gas sources and improved economics of producing natural gas and oil from such sources has and will likely continue to exert downward pricing pressures on the price of crude oil and natural gas. The rise in production of crude oil and natural gas from shale in North America and the increased use of large Liquefied Natural Gas export facilities around the world are, at least to date, significant contributors of supply to the crude oil and natural gas market. Production of crude oil and natural gas from unconventional sources has benefited from improved drilling efficiencies that have lowered the costs of extraction from these sources. The rise in production of natural gas and oil from these sources not only affects the price of natural gas and oil but can also result in a reduction of capital invested in offshore oil and natural gas exploration. Because the Company provides vessels servicing offshore oil and natural gas exploration, a significant reduction in investments in offshore exploration and development in favor of investments in these unconventional resources could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company may record additional losses or impairment charges related to sold or idle vessels. Prolonged periods of low utilization or low day or charter rates, the sale of assets below their then carrying value or the decline in market value of the Company’s assets may cause the Company to record additional impairments. If there are indications that the carrying value of any of the Company’s vessels or other tangible assets may not be recoverable or if the Company sells assets for less than their carrying value, the Company may recognize additional impairment charges on its fleet. During 2023 and 2022, the Company recognized impairment charges of $0.7 million and $2.9 million, respectively, related to tangible assets. There is a high level of competition in the offshore marine service industry. The Company operates in a highly fragmented and competitive industry, and the competitive nature of its industry could depress charter and utilization rates and adversely affect the Company’s financial performance. The Company competes for business on the basis of price, reputation for excellent service, quality, suitability and technical capabilities of its vessels, availability of vessels, safety and efficiency (including with respect to fuel usage and carbon emissions), cost of mobilizing vessels from one market to a different market, and national flag preference. In addition, the Company’s ability to compete in international markets may be adversely affected by regulations requiring, among other things, local construction, flagging, ownership or control of vessels, the awarding of contracts to local contractors, the employment of local citizens and/or the purchase of supplies from local vendors. Furthermore, the Company competes with companies that have undergone significant capital restructuring which has substantially reduced their debt levels thereby vastly improving their balance sheets. The process of obtaining new charter agreements is highly competitive and generally involves an intensive screening and a competitive bidding process, which, in certain cases, may extend for several months. The Company’s existing and potential competitors may have significantly greater financial resources than the Company. In addition, competitors with greater resources may have larger fleets, or could operate larger fleets through consolidations, acquisitions, new buildings or pooling of their vessels with other companies, and, therefore, may be able to offer a more competitive service than the Company, including better charter rates. The Company expects competition from a number of experienced companies providing contracts to potential customers, including state-sponsored entities and major energy companies affiliated with the projects requiring offshore vessel services. As a result, the Company may be unable to expand its relationships with existing customers or to obtain new customers on a profitable basis, if at all. If the Company is unable to successfully compete, it could have a materially adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. Furthermore, competition may begin to emerge on the basis of information technology infrastructure as well. The Company expects its competitors to improve their information technology systems, including with the use of artificial intelligence (“AI”) and machine learning solutions, to interact with customers and vendors, capture knowledge regarding vessel operation systems including vessel positioning and scheduling, provide regular updates on maintenance status and predict maintenance requirements and to provide real time emission tracking. The Company’s ability to innovate its own technology infrastructure and appropriately address user experience will affect our ability to compete. 18 An oversupply of vessels or equipment that serve offshore oil and natural gas operations could have an adverse impact on the charter rates earned by the Company’s vessels and equipment. The Company’s industry is highly competitive, with intense price competition and highly sensitive to the supply of vessel capacity. For example, expansion of the supply of vessels and equipment that serve offshore oil and natural gas operations in the decade prior to 2017 increased competition in the Company’s markets and affected prices charged by operators. Additionally, the refurbishment of disused or “mothballed” vessels, conversion of vessels from uses other than oil and natural gas exploration and production support and related activities or construction of new vessels and equipment could add vessel and equipment capacity to current worldwide levels. While the Company does not anticipate any significant expansion of the supply of vessels in the near-term, any oversupply of vessels and equipment capacity in the offshore marine market could lower charter rates and result in lower operating revenues, which in turn could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company relies on several customers for a significant share of its revenues, the loss of any of which could adversely affect the Company’s business and operating results. The Company derives a significant portion of its revenues from a limited number of oil and natural gas exploration, development and production companies, and wind farm construction companies. During the years ended December 31, 2023, 2022, and 2021, the Company’s ten largest customers accounted for approximately 73%, 66% and 81%, respectively, of its operating revenues. During the year ended December 31, 2023, three customers, ExxonMobil, SEACOR Marine Arabia, a joint venture through which vessels are chartered to Saudi Aramco, and Azule were together responsible for 48% or more of the Company’s operating revenues from continuing operations. In addition, one or more of the Company's joint ventures may rely primarily on a single customer for their revenues. The portion of the Company’s revenues or any of its joint ventures’ revenues attributable to any single customer may change over time, depending on the level of activity by any such customer, the Company’s ability to meet the customer’s needs and other factors, many of which are beyond the Company’s control. Additionally, most of the Company’s contracts with its customers can be canceled on relatively short notice and do not commit its customers to acquire specific amounts of services or require the payment of significant liquidated damages upon cancellation. The loss of business from any of the Company’s significant customers, whether temporary or permanent, the result of competition, military conflict or changes in consumer preferences, could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. Further, to the extent any of the Company’s customers experience an extended period of operating difficulty, it may have a material adverse effect on the Company’s business, financial position, results of operation, cash flows and prospects. Consolidation of the Company’s customer base could adversely affect demand for its services and reduce its revenues. In recent years, oil and natural gas companies, energy companies, drilling contractors and other offshore service providers have undergone substantial consolidation and additional consolidation is possible. Consolidation results in fewer companies to charter or contract for the Company’s services. Also, merger activity among both major and independent oil and natural gas companies affects exploration, development and production activity as the consolidated companies integrate operations to increase efficiency and reduce costs. Less promising exploration and development projects of a combined company may be dropped or delayed. Such activity may result in an exploration and development budget for a combined company that is lower than the total budget of both companies before consolidation, which could adversely affect demand for the Company’s vessels thereby reducing its revenues. While increasing offshore wind farm development, particularly in the U.S., has provided opportunities to work with new customers, such opportunities may be insufficient to offset a decline in oil and natural gas customers. 19 The Company may be unable to maintain or replace its vessels as they age. As of December 31, 2023, the average age of the Company’s owned vessels was approximately ten years. The Company believes that after a vessel has been in service for approximately 20 years, the expense (which typically increases with age) necessary to satisfy required marine certification standards may not be economically justifiable. In addition, the Company must maintain its vessels to remain attractive to its customers and comply with regulations, including updating or replacing systems and equipment. However, the Company may be unable to carry out drydockings of its vessels, may be limited by insufficient shipyard capacity or its systems and equipment may become obsolete and unsupported by the manufacturer or other service providers, which could adversely affect its ability to maintain its vessels. In addition, market conditions may not justify these expenditures or enable the Company to operate its older vessels profitably during the remainder of their economic lives. There can be no assurance that the Company will be able to maintain its fleet by extending the economic life of existing vessels, or that its financial resources will be sufficient to enable it to make expenditures necessary for these purposes or to acquire or build replacement vessels, all of which could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The failure to successfully complete construction or conversion, repairs, maintenance or routine drydockings of the Company's vessels on schedule and on budget could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. From time to time, the Company may have a number of vessels under conversion and may plan to construct or convert other vessels in response to current and future market conditions. The Company also routinely engages shipyards to drydock vessels for regulatory compliance and to provide repair and maintenance. Construction and conversion projects, drydockings and other repair and maintenance are subject to risks of delay and cost overruns, resulting from shortages of equipment, supply chain disruptions, lack of shipyard availability, lack of sufficient skilled personnel at the shipyards, unforeseen engineering problems, work stoppages, weather interference, unanticipated cost increases arising from inflation or otherwise, inability to obtain necessary certifications and approvals and shortages of materials or skilled labor. A significant delay in construction, drydockings or other repair and maintenance could have a material adverse effect on contract commitments and revenues with respect to vessels under construction, conversion or undergoing drydockings or other repair and maintenance. Significant cost overruns or delays for such vessels could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company’s inability to attract and retain qualified personnel and crew its vessels could have an adverse effect on its business. Attracting and retaining skilled personnel is an important factor in the Company’s future success. In addition, the success of the Company is dependent upon its ability to adequately crew its vessels. The market for qualified personnel is highly competitive, particularly in the last few years, and global and/or regional conflicts, such as the conflict between Russia and Ukraine and the conflicts in the Middle East, may further reduce or restrict the availability of qualified personnel or the willingness of qualified personnel to operate in certain regions, particularly with respect to certain technical and engineering positions, including marine officers. The Company cannot be certain that it will be successful in attracting and retaining qualified personnel and crewing its vessels in the future. The Company has faced and may continue to face difficulties attracting, hiring and retaining highly-skilled personnel with appropriate qualifications and may not be able to fill open positions. To attract top talent, the Company has had to offer, and believes it will need to continue to offer, attractive compensation and benefits packages before the Company can validate the productivity of those employees. The Company has increased, and expects to continue to increase, its employee compensation levels in response to competition, as necessary. In addition, the pressures of inflation have led to increased costs of labor over the past few years and will likely continue to do so. Many of the companies with which the Company competes for personnel have greater financial and other resources than the Company does and may be able to absorb the increasing costs of labor easier than the Company can. If the Company fails to retain key personnel and hire, train and retain qualified employees, the Company may not be able to compete effectively and may have increased incident rates as well as regulatory and other compliance failures, which could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. As part of the Company’s ongoing management of its fleet and personnel, the Company may need to improve its operations and financial systems and recruit additional staff; if the Company cannot improve these systems or recruit suitable employees, the Company’s business and results of operations may be adversely affected. The Company has and may continue to need to invest in upgrading its operating and financial systems. In addition, the Company may have to recruit additional well-qualified shoreside administrative and management personnel. The Company may not be able to hire suitable employees. For example, the Company’s operations require technically skilled staff with specialized training. Competition for these employees is intense. If the Company is unable to employ such technically skilled staff, the Company may not be able to adequately support the operations of the Company’s vessels. If the Company is unable to operate its financial and operations systems effectively or is unable to recruit suitable employees, the Company’s results of operation and its ability to manage and expand its fleet may be adversely affected. 20 The operations of the Company’s fleet may be subject to seasonal factors. Demand for the Company’s offshore support services is directly affected by the levels of offshore drilling and production activity of its oil and natural gas customers, and construction and maintenance activity for its wind farm customers. Budgets of many of the Company’s customers are based upon a calendar year, and demand for the Company’s services has historically been stronger in the second and third calendar quarters when allocated budgets are expended by its customers and weather conditions are more favorable for offshore activities in the northern hemisphere. In particular, the demand for the Company’s liftboat fleet in the U.S. Gulf of Mexico and offshore support vessels in Europe, the Middle East and West Africa, are seasonal with peak demand normally occurring during the summer months. Adverse events relating to the Company’s vessels or business operations during peak demand periods could have a significant adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. In addition, seasonal volatility can create unpredictability in activity and utilization rates, which could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company has high levels of fixed costs that will be incurred regardless of its level of business activity. The Company’s business has high fixed costs, including administrative and general expenses. Maintenance downtime or low productivity due to reduced demand can have a significant negative effect on the Company’s operating results and financial condition. Some of the Company’s fixed costs will not decline during periods of reduced revenue or activity. During times of reduced utilization, the Company may not be able to reduce its costs immediately as it may incur additional costs associated with preparing vessels for cold stacking. Moreover, the Company may not be able to fully reduce the cost of its support operations in a particular geographic region due to the need to support the remaining vessels in that region or otherwise reduce its administrative and general expenses. A decline in revenue due to lower day rates and/or utilization may not be offset by a corresponding decrease in the Company’s fixed costs and could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company may be required to incur higher than expected costs to return previously cold-stacked vessels to class. As of December 31, 2023, three of 55 owned and leased-in vessels were cold-stacked worldwide and, if the industry experiences another downturn, the Company may determine to cold-stack additional vessels in response to such downturn. No assurance can be given that the Company will be able to quickly bring these cold-stacked vessels back into service or that the cost of doing so would not be significant. Cold-stacked vessels do not receive the same level of maintenance as active vessels. As a result and depending on the length of time the vessels are cold-stacked, the Company could incur deferred drydocking costs for regulatory recertification to return these vessels to active service and may incur costs to hire and train mariners to operate such vessels. These costs are difficult to estimate and could be substantial. Delay in reactivating cold-stacked vessels and the costs and other expenses related to the reactivation of cold- stacked vessels could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. 21 Inflation and increased interest rates may increase the Company’s operating and capital costs. In 2022, the U.S. and other developed countries experienced significantly heightened inflationary pressures related to the policies implemented during COVID-19 and the ensuing economic recovery, causing disruptions in demand, supply chains, and labor markets. The general economy in 2022 was also affected by the war in Ukraine and associated increase in energy costs. While the global inflation rate began to stabilize and, in some cases decline, in 2023 as a result of central bank policy tightening, core inflation has proved persistent as a result of the preceding factors, in addition to others such as the escalating number of significant conflicts throughout the globe. The Company expects these inflationary pressures to continue to impact its margins and more generally, its business in 2024. The Company may not be able to renew or replace expiring contracts for its vessels. The Company’s ability to renew or replace expiring contracts or obtain new contracts, and the terms of any such contracts, will depend on various factors, including market conditions and the specific needs of its customers. Given the highly competitive and historically cyclical nature of the industry, the Company may not be able to renew or replace expiring contracts or it may be required to renew or replace expiring contracts or obtain new contracts at rates that are below, and potentially substantially below, existing day rates, or that have terms that are less favorable to the Company than its existing contracts, or it may be unable to secure contracts for these vessels. This could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The early termination of contracts on the Company’s vessels could have a material adverse effect on its operations. Most of the long-term contracts for the Company’s vessels contain early termination options in favor of the customer. Although some of such contracts have early termination remedies or other provisions designed to discourage the customer from exercising such options, the Company cannot assure investors that its customers would not choose to exercise their termination rights in spite of such remedies or the threat of litigation with the Company. Often these remedies do not fully compensate the Company for loss of the contract. Until replacement of such business with other customers, any termination could adversely affect the Company’s financial condition and results of operations. The Company might not be able to replace such business on economically equivalent terms. In addition, during prior downturns, the Company has experienced customers requesting contractual concessions even though such concessions were contrary to existing contractual terms. While the Company may not be legally required to give concessions, commercial considerations may dictate that it do so. If the Company is unable to collect amounts owed to it or long-term contracts for its vessels are terminated and its vessels are not sufficiently utilized, this could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company relies on information technology, and if it is unable to protect against service interruptions, data corruption, cyber- based attacks or network security breaches, its operations could be disrupted and its business could be negatively affected. The Company relies on information technology networks and systems, including the Internet and cloud services, to process, transmit and store electronic and financial information, manage a variety of business processes and activities, and comply with regulatory, legal and tax requirements. The Company also depends on its information technology infrastructure to capture knowledge of its business including its vessel operation systems containing information about vessel positioning and scheduling; monitor its vessel maintenance and engine systems; to coordinate its business across its bases of operation including cargo delivery and equipment tracking; and communicate within its organization and with customers, suppliers, partners and other third parties. The Company’s ability to service customers and operate vessels is dependent on the continued operation of these systems. While the Company takes various precautions and has enhanced controls around its IT systems, like other technology systems, they are susceptible to damage, disruptions or shutdowns, hardware or software failures, power outages, computer viruses, telecommunication failures, user errors, catastrophic events, or cyber-attacks including malware, other malicious software, phishing email attacks, attempts to gain unauthorized access to its data, the unauthorized release, corruption or loss of its data, loss or damage to its data delivery systems, ransomware, and other electronic security breaches. Over time, the techniques used to conduct these cyber-attacks, as well as the sources and targets of these attacks, have changed and become increasingly sophisticated and, in some cases, are not recognized until such attacks are launched or have been in place for some time. In addition, there has been an increase in cyber-attacks conducted or sponsored by capable and well-funded “nation state” operators. The Company expects that sophistication and techniques of cyber-threats will continue to evolve as threat actors increase their use of AI and machine-learning technologies. The Company’s information technology systems are in some cases integrated, such that damage, disruption or shutdown to one system could result in a more widespread impact. If the Company’s information technology systems suffer severe damage, disruption or shutdown, and its business continuity plans do not effectively resolve the issues in a timely manner, the Company’s business could be negatively affected. In addition, cyber-attacks could lead to potential unauthorized access and disclosure of confidential information, data loss and corruption. As a result of a cyber-attack the Company could also be vulnerable to fraud. While the Company is not currently aware of any material impact from cyber-attacks and the Company continues to devote time and resources to the remediation of such risks, there is the possibility of a material impact from such an attack in the future. Recent action by the IMO’s Maritime Safety Committee and U.S. agencies indicate that cybersecurity regulations for the maritime industry are likely to be further developed in the near future in an attempt to combat cybersecurity threats. The Company is 22 unable to predict the impact of such regulations at this time. Further, as the threat of cyber-attacks continues to grow, the Company will be required to expend additional resources to continue to modify or enhance its protective measures or to investigate and remediate any vulnerabilities to cyber-attacks. Failure to comply with data protection and privacy laws could lead to financial penalties and reputational harm. Data protection laws apply to the Company in certain countries in which the Company does business. Specifically, the E.U. General Data Protection Regulation (the “GDPR”), increased penalties up to a maximum of 4% of global annual turnover for breach of the regulation. The GDPR requires mandatory breach notification, the standard for which is also followed outside the E.U., particularly in Asia. Non-compliance with data protection laws could expose the Company to regulatory investigations, which could result in fines and penalties. In addition to imposing fines, regulators may also issue orders to stop processing personal data, which could disrupt operations. The Company could also be subject to litigation from persons or corporations allegedly affected by data protection violations. Violation of data protection laws is a criminal offence in some countries, and individuals can be imprisoned or fined. Any violation of these laws or harm to the Company’s reputation could have a material adverse effect on the Company’s business, financial condition, results of operations, cash flows and prospects. Increased domestic and international laws and regulations may materially adversely impact the Company, and the Company may become subject to additional international laws and regulations in the event of high-profile incidents. Regulation of the offshore marine industry has intensified over the past several decades, and the Company expects this trend to continue. Changes in laws or regulations regarding offshore oil and natural gas exploration and development activities and technical and operational measures may increase the Company’s costs and the costs of its customers’ operations. For instance, in response to fatalities and environmental damages caused by a 2010 explosion on the Deepwater Horizon, a drilling rig operating in the U.S. Gulf of Mexico, various regulatory agencies imposed temporary moratoria on drilling operations and enacted several permanent regulations designed to enhance the safety of operations in the U.S. Gulf of Mexico. Compliance with these new regulations and new interpretations of existing regulations have materially increased the cost of drilling operations in the U.S. Gulf of Mexico. New or additional government regulations or laws concerning drilling operations in the U.S. Gulf of Mexico and other regions have in the past and could in the future materially increase the cost of drilling operations in those markets or cause additional moratoria on drilling activities. These changes could decrease offshore operations or investments by the Company’s current or prospective customers, and thereby reduce the demand for the Company’s services. Moreover, continuing changes in regulation increase our compliance costs and make it more difficult for the Company to implement long-term plans. In addition, the bodies that regulate maritime operations are considering enacting regulations meant to safeguard the industry and its participant from cyber-threats. These regulations could lead to additional costs for the Company, as well as disruption to its information technology systems. For these reasons, further changes in regulation could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Outer Continental Shelf Lands Act, as amended, provides the federal government with broad discretion in regulating the leasing of offshore resources for the production of oil and natural gas. The Outer Continental Shelf Lands Act provides the federal government with broad discretion in regulating the release or continued use of offshore resources for oil and natural gas production. Various political leaders and public interest groups oppose further leasing, which creates uncertainties regarding the current and future level of permitted offshore leasing. New offshore oil and natural gas drilling may be subject to continuing or newly enacted moratoriums. Because the Company’s operations rely on offshore oil and natural gas exploration and production, the government’s exercise of authority under the provisions of the Outer Continental Shelf Lands Act to restrict the availability of offshore oil and natural gas leases (due to accidents, environmental concerns or otherwise) could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company is subject to complex laws and regulations, including environmental laws and regulations, that can adversely affect the cost, manner or feasibility of doing business. Increasingly stringent federal, state, local and international laws and regulations governing worker safety and health and the staffing, construction and operation of vessels significantly affect the Company’s operations. Many aspects of the marine industry are subject to extensive governmental regulation and oversight, including by the USCG, Occupational Safety and Health Administration (“OSHA”), the NTSB, the IMO, the U.S. Department of Homeland Security, MARAD, CBP, BSEE, the EPA and various other foreign, state or local environmental protection agencies for those jurisdictions in which the Company operates, and to regulation by various international bodies and classification societies (such as ABS). The Company is also subject to regulation under international treaties, such as (i) MARPOL, (ii) SOLAS, (iii) MLC, (iv) BWM Convention, (v) STCW and (vi) other port regulations. These agencies, organizations, regulations and treaties establish safety requirements and standards and are authorized to investigate vessels and accidents and to recommend improved safety standards. CBP and USCG are authorized to inspect vessels at will. The Company has and will continue to spend significant funds to comply with these regulations and treaties. Failure to comply with these regulations and treaties may cause the Company to incur significant liabilities or restrictions on its operations, any of which could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. 23 The Company’s business and operations are subject to federal, state, local and international laws, regulations and treaties relating to environmental protection, including laws and regulations that govern the handling, storage and discharge of various hazardous substances. Violations of these laws may result in civil and criminal penalties, fines, injunctions, or other sanctions, or the suspension or termination of the Company’s operations. Compliance with such laws and regulations frequently requires installation of costly equipment, increased staffing, increased fuel costs, specific training, or operational changes. Some environmental laws impose strict and, under certain circumstances, joint and several liability for remediation of spills and releases of oil and hazardous materials and damage to natural resources, which could subject the Company to liability without regard to whether it is negligent or at fault. Under OPA 90, owners, operators and bareboat charterers are jointly and severally strictly liable for the removal costs and damages resulting from the discharge of oil within the navigable waters of the U.S. and the EEZ. In addition, an oil spill could result in significant liability, including fines, penalties, criminal liability and costs for natural resource and other damages under other federal and state laws and civil actions. Liability for a catastrophic spill could exceed the Company’s available insurance coverage and result in adverse impacts on the Company, including having to liquidate assets to pay claims. These laws and regulations may expose the Company to liability for the conduct of or conditions caused by others, including charterers. Because such laws and regulations frequently change and may impose increasingly strict requirements, the Company cannot predict the ongoing cost of complying with these laws and regulations. Additionally, reduced enforcement of existing safety and other laws or regulations may result in a decline in the demand for the Company’s offshore support services that are provided in connection with compliance with such laws or regulations. The Company cannot be certain that existing laws, regulations or standards (and the enforcement thereof), as currently interpreted or reinterpreted in the future, or future laws and regulations and standards will not have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. Regulation of the offshore marine services industry will likely continue to become more stringent and more expensive for the Company. In addition, a serious marine incident that results in significant pollution or injury could result in additional regulation and lead to strict governmental enforcement or other legal challenges. The variability and uncertainty of current and future shipping regulations could hamper the ability of the Company and its customers to plan for the future or establish long-term strategies. Additional environmental and other requirements, as well as more stringent enforcement policies, may be adopted that could limit the Company’s ability to operate, require the Company to incur substantial additional costs or otherwise have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. For more information, see “Item 1. Business—Governmental Regulations—Regulatory Compliance” of this Annual Report on Form 10-K. The Company is required by various governmental and quasi-governmental agencies to obtain, maintain and periodically renew certain permits, licenses and certificates with respect to its operations or vessels. In certain instances, the failure to obtain, maintain or renew these authorizations could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. There are risks associated with climate change, environmental regulations and evolving environmental expectations. Governments, supranational groups and various other parties around the world, including some of the world’s largest investment managers and proxy advisors, have, in recent years, proposed or adopted new laws, regulations and/or policies pertaining to climate change, carbon emissions or energy use that could result in a reduction in demand for hydrocarbon-based fuel. In fact, many countries and organizations have adopted, or are considering the adoption of, regulatory frameworks to reduce greenhouse gas emissions. These regulatory measures, international treaties and policies may include, among others, adoption of cap and trade regimes, carbon taxes, increased efficiency standards, and incentives or mandates for renewable energy and could include specific restrictions on shipping emissions. In addition, recent regulations proposed by, among others, the SEC, will require reporting of greenhouse gas emissions by U.S. public reporting companies annually (including us), which may result in an increased effort by such companies to reduce such emissions through energy transition initiatives. Additionally, some institutional investors and other groups have focused on matters affecting the environment, which may result in reduced investment in, or financing available to, companies engaged in the hydrocarbon-based industry, or that provide services to such companies. Many of these groups have developed environmental, social and governance standards as benchmarks and are using those benchmarks to inform their investment criteria. Customers are also becoming increasingly focused on these matters and have started choosing suppliers based on factors other than price and availability, such as supplier focus on ESG matters and use of more energy efficient equipment and vessels. If the Company is unable to keep up with best practices on a climate basis, the Company could fall behind its competitors and industry trends. Although the Company formed a new Sustainability Council in 2020 to oversee the Company’s enhanced environmental, social and governance program and published its Inaugural Sustainability Report, the Company may not meet these evolving standards or benchmarks and even if it does, these investors and groups may choose to forego investments in oil and natural gas related industries. The Company’s ability to achieve any of its stated sustainability commitments is subject to numerous factors and conditions, many of which are outside of the Company’s control. The Company’s efforts to research, establish, accomplish, and accurately report on these commitments expose it to numerous operational, reputational, financial, legal, and other risks, any of which could have a negative impact on the Company’s business takes and could negatively impact the Company’s business. Similarly, any actual or perceived failure to achieve the Company’s environmental, social or governance commitments, goals, initiatives or mandates could harm the Company’s reputation, expose it to potential claims or adversely impact its business, stock price or access to capital. Additionally, positions the Company takes or does not take on these issues could negatively impact the Company’s ability to attract or retain customers or employees. 24 Several governmental and non-governmental bodies continue to request further disclosures of information relating to environmental, social and governance matters. The Company will be exposed to higher costs and enhanced risks of the type described above to the extent it increases its required or voluntary disclosures regarding these matters. The Company’s processes and controls for reporting environmental, social and governance matters are evolving along with multiple disparate standards for identifying, measuring and reporting related metrics. The Company cannot assure you that its processes and controls will successfully permit it to report such data in a manner that complies with its standards or those of others, or is otherwise satisfactory to its various stakeholders and regulators. Governments could also pass laws or regulations encouraging or mandating the use of alternative energy sources such as wind power and solar energy. These requirements could reduce demand for oil and natural gas and therefore the services provided by the Company. In addition, new environmental or emissions control laws or regulations may require an increase in the Company’s operating costs and/or in its capital spending for additional equipment or personnel to comply with such requirements and could also result in a reduction in revenues due to downtime required for the installation of such equipment. Moreover, various international conventions and federal, state or international laws have significantly increased their regulation of vessel fuel and emissions in recent years, and the Company expects this trend to continue. Any of these developments, requirements or initiatives could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. From time to time, extreme weather causes the Company or its customers to suspend business operations. Climate change may increase the frequency and severity of these extreme weather events and certain adverse weather patterns in the future, which could increase the Company’s exposure to suspended operations and/or put the Company’s properties at risk for weather related damage. Climate change may also affect our ability to procure insurance for the Company’s vessels as well as its facilities in areas with higher exposure to the effects of climate change or to repair and rebuild such facilities if needed in the future. Concern over climate change may also result in new or increased legal or regulatory requirements, which could accelerate the above-described trends towards enhanced regulation of the Company’s operations. In addition, there may be significant physical effects of climate change from such emissions that have the potential to negatively impact the Company’s customers, personnel, and physical assets, any of which could adversely impact cargo levels, the demand for the Company’s services, or the Company’s ability to recruit personnel and operate efficiently. Climate change-related regulatory activity and developments may adversely affect the Company’s business and financial results by requiring the Company to make capital investments in new equipment or technologies, pay for carbon emissions, purchase carbon offset credits, or otherwise incur additional costs or take additional actions related to its emissions. Such activity may also impact the Company indirectly by increasing our operating costs, including fuel costs. Regulatory developments may also result in the inability to operate ships that do not meet certain standards, the acceleration of the removal of less fuel-efficient ships from the Company’s fleet and impact the resale value of its vessels in the future. In addition, regulatory developments may restrict or limit the Company’s access to certain countries or curtail the Company’s services. The Company has significant international operations, which subjects it to risks. Unstable political, military and economic conditions in foreign countries where a significant proportion of the Company’s operations is conducted could materially adversely impact its business. The Company operates vessels and transacts other business worldwide. For the years ended December 31, 2023, 2022 and 2021, 79%, 72% and 88%, respectively, of the Company’s operating revenues and $3.6 million, $7.0 million and $15.4 million, respectively, of its equity in earnings from 50% or less owned companies, net of tax, were derived from foreign operations. These operations are subject to risks, including potential vessel seizure, terrorist acts, piracy, kidnapping, nationalization of assets, currency restrictions, import or export quotas, tariffs and other forms of public and government regulation, all of which are beyond the Company’s control. Economic sanctions or an oil embargo, for example, could have significant impact on activity in the oil and natural gas industry and, correspondingly, on the Company should it operate in an area subject to any sanctions or embargo, or in the surrounding region to the extent any sanctions or embargo disrupts its operations. In addition, the Company’s ability to compete in international markets may be adversely affected by foreign government regulations that favor or require the awarding of contracts to local competitors, or that require foreign persons to employ citizens of, or purchase supplies from, a particular jurisdiction. Further, the Company’s foreign subsidiaries may face governmentally imposed restrictions on their ability to transfer funds to their parent company. Activity outside the U.S. involves additional risks, including the possibility of: • U.S. embargoes or restrictive actions and regulations by U.S. and foreign governments that could limit the Company’s ability to provide services in foreign countries or cause retaliatory actions by such governments; • • a change in, or the imposition of, withholding or other taxes on foreign income, tariffs or restrictions on foreign trade and investment; limitations on the repatriation of earnings or currency exchange controls and import/export quotas; 25 • • • • • • • • • • • • • unwaivable, burdensome local cabotage, local content and local ownership laws and requirements; nationalization, expropriation, asset seizure, blockades and blacklisting; limitations in the availability, amount or terms of insurance coverage; loss of contract rights and inability to enforce contracts; political instability, war and civil disturbances or other risks that may limit or disrupt markets, such as terrorist acts, piracy and kidnapping; fluctuations in currency exchange rates, hard currency shortages and controls on currency exchange that affect demand for the Company’s services and its profitability; potential noncompliance with a wide variety of laws and regulations, such as the FCPA, and similar non-U.S. laws and regulations, including the United Kingdom (U.K.) Bribery Act 2010; labor strikes; import or export quotas and other forms of public and government regulation; changes in general economic and political conditions; regional conflicts, including in Ukraine, Israel and around the Red Sea; difficulty in staffing and managing widespread operations, including the ability to transfer qualified labor to local operations; and inadequate or delayed response to natural disasters or other major incidents or events in less developed countries. Some of the Company’s customers are located in emerging markets, which can further exacerbate the foregoing risks. Russia’s invasion of Ukraine on February 24, 2022, and its resulting impacts, including supply chain disruptions, increased fuel prices, international sanctions and other measures that have been imposed, have adversely affected, and may continue to adversely affect, the Company’s business and services, including our employees from or located in Ukraine. These factors may also have the effect of heightening many other risks to the Company’s business, any of which could materially and adversely affect the business and results of operations. In addition, the current hostilities in Gaza Strip have and could continue to escalate and involve surrounding countries in the Middle East. For example, the Yemen-based Houthi rebels and other agitators have attacked several ships, including commercial and military vessels, in the Bab al-Mandeb strait, one of the densest shipping lanes in the world. Although the length, impact, and outcome of the hostilities in the Middle East is highly unpredictable, this conflict could lead to significant market and other disruptions, including disruptions to the Company’s operations in the region. One of our largest customers is SEACOR Marine Arabia, a joint venture that is 45% owned by a subsidiary of SEACOR Marine and through which vessels are in service to Saudi Aramco, the national oil company of Saudi Arabia. The Company is subject to hazards inherent in the operation of offshore support and related vessels and has experienced accidents that have resulted in the loss of life, disrupted operations and caused reputational harm. The operation of offshore support and related vessels is highly dangerous and is inherently subject to various risks including, but not limited to, adverse and sea conditions, catastrophic disaster, mechanical failure, navigation errors, capsizing, grounding, hazardous substance spills, and collision, each of which could result in the loss of life, injury to personnel, and damage to equipment and the environment. For instance, the Company’s operations in the U.S. Gulf of Mexico may be adversely affected by weather. The Atlantic hurricane season typically runs from June through November. Tropical storms and hurricanes may limit the Company’s ability to operate vessels in the proximity of storms, reduce oil and natural gas exploration, development and production activity, and could result in the Company incurring additional expenses to secure equipment and facilities. They may also require the Company to evacuate its vessels, personnel and equipment out of the path of a storm. If any of these events were to occur, the Company could be held liable for resulting damages, including loss of revenues from or termination of charter contracts, higher insurance rates, increased operating costs, increased governmental regulation and reporting and damage to the Company’s reputation and customer relationships. Any such events would likely result in negative publicity for the Company and adversely affect its safety record, which would affect demand for its services in a competitive industry. In addition, the affected vessels could be removed from service and would then not be available to generate revenues. 26 Our vessels have been involved in accidents in the past, some of which included loss of life, personal injury and property damage, and we, or third parties operating our vessels, may experience accidents in the future. For example, on April 13, 2021, the SEACOR Power, a liftboat owned by a subsidiary of the Company with nineteen individuals on board, capsized off the coast of Port Fourchon, Louisiana. The incident resulted in the death of several crew members, including the captain of the vessel and five other employees of the Company. The incident also resulted in the constructive total loss of the SEACOR Power. In 2023, another one of the Company’s liftboats experienced an incident that did not cause any casualties but led to significant downtime for the vessel. The NTSB and the USCG have each conducted an investigation to determine the cause of the incident and released their respective final reports. The NTSB’s report determined that the probable cause of the capsizing of the SEACOR Power was a loss of stability that occurred when the vessel was struck by severe thunderstorm winds, which exceeded the vessel’s operation wind speed limits. The NTSB further determined that contributing to the loss of life on the vessel was the speed at which the vessel capsized and the angle at which it came to rest, which made egress difficult, and the high winds and seas in the aftermath of the capsizing, which hampered rescue efforts. The USCG’s report is consistent with the determinations of the NTSB. Numerous civil lawsuits were filed against the Company and other third parties by the family members of deceased crew members and the surviving crew members employed by the Company or by third parties. On June 2, 2021, the Company filed a Limitation of Liability Act complaint in federal court in the Eastern District of Louisiana (“Limitation Action”), which had the effect of enjoining all existing civil lawsuits and requiring the plaintiffs to file their claims relating to the capsizing of the SEACOR Power in the Limitation Action. All injury and death claims in the Limitation Action for which the Company has financial exposure have been resolved, and the remaining claims are those for which the Company is owed contractual defense and indemnity or will be covered by insurance. Failure to maintain an acceptable safety record may have an adverse impact on the Company’s ability to retain customers. The Company’s customers consider safety and reliability a primary concern in selecting a service provider. The Company must maintain a record of safety and reliability that is acceptable to its customers. Should this not be achieved, the ability to retain current customers and attract new customers may be adversely affected, which in turn could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company’s insurance coverage may be inadequate to protect it from the liabilities that could arise in its business. Although the Company maintains insurance coverage against the risks related to its business, risks may arise for which it may not be insured. Claims covered by insurance are subject to deductibles, the aggregate amount of which could be material, and certain policies impose caps on coverage. Insurance policies are also subject to compliance with certain conditions, the failure of which could lead to a denial of coverage as to a particular claim or the voiding of a particular insurance policy. There also can be no assurance that existing insurance coverage can be renewed at commercially reasonable rates or that available coverage will be adequate to cover future claims. If a loss occurs that is partially or completely uninsured, or the carrier is unable or unwilling to cover the claim, the Company could be exposed to substantial liability. Further, to the extent the proceeds from insurance are not sufficient to repair or replace a damaged asset, the Company would be required to expend funds to supplement the insurance and in certain circumstances may decide that such expenditures are not justified, which, in either case, could adversely affect the Company’s business, financial position, results of operations, cash flows and prospects. The Company may not be fully indemnified by its customers for damage to their property or the property of their other contractors. The Company’s contracts are individually negotiated, and the levels of indemnity and allocation of liabilities in them can vary from contract to contract depending on market conditions, particular customer requirements and other factors existing at the time a contract is negotiated. Additionally, the enforceability of indemnification provisions in the Company’s contracts may be limited or prohibited by applicable law or may not be enforced by courts having jurisdiction, and the Company could be held liable for substantial losses or damages and for fines and penalties imposed by regulatory authorities. The indemnification provisions of the Company’s contracts may be subject to differing interpretations, and the laws or courts of certain jurisdictions may enforce such provisions while other laws or courts may find them to be unenforceable, void or limited by public policy considerations, including when the cause of the underlying loss or damage is the Company’s gross negligence or willful misconduct, when punitive damages are attributable to the Company or when fines or penalties are imposed directly against the Company. The law with respect to the enforceability of indemnities varies from jurisdiction to jurisdiction. Current or future litigation in particular jurisdictions, whether or not the Company is a party, may impact the interpretation and enforceability of indemnification provisions in the Company’s contracts. There can be no assurance that the Company’s contracts with its customers, suppliers and subcontractors will fully protect the Company against all hazards and risks inherent in its operations. There can also be no assurance that those parties with contractual obligations to indemnify the Company will be financially able to do so or will otherwise honor their contractual obligations. 27 The Company may undertake one or more significant corporate transactions that may not achieve their intended results, may adversely affect its financial condition and its results of operations, and may result in additional risks to its business. The Company continuously evaluates the acquisition and disposition of assets relevant to participants in the offshore energy industry and may in the future undertake significant transactions. Any such transaction could be material to the Company’s business and could take any number of forms, including mergers, joint ventures, investments in new lines of business and the purchase of equity interests or other assets. The form of consideration associated with such transactions may include, among other things, cash, Common Stock, securities convertible into Common Stock or other securities (privately or through a public offering), equity interests in the Company’s subsidiaries, or other assets of the Company. The Company also evaluates the disposition of its assets, in whole or in part, which could take the form of asset sales, mergers or sales of equity interests in its subsidiaries (privately or through a public offering). These types of significant transactions may present material risks and uncertainties, including distraction of management from current operations, insufficient revenue to offset liabilities assumed, potential loss of significant revenue and income streams, unexpected expenses, inadequate return of capital, potential acceleration of taxes currently deferred, regulatory or compliance issues, the triggering of certain covenants in the Company’s debt instruments (including accelerated repayment) and other unidentified issues not discovered in due diligence. If the Company was to complete such an acquisition, disposition, investment or other strategic transaction, it may require additional debt or equity financing that could result in a significant increase in the amount of debt the Company has or the number of outstanding shares of its Common Stock. As a result of the risks inherent in such transactions, the Company cannot guarantee that any such transaction will ultimately result in the realization of the anticipated benefits of the transaction or that significant transactions will not have a material adverse impact on the Company’s business, financial positions, results of operations, cash flows and prospects. If the Company does not restrict the amount of ownership of its Common Stock by non-U.S. citizens, it could be prohibited from operating offshore support vessels in the U.S., which would adversely impact the Company’s business and operating results. The Company is subject to the Jones Act, which governs, among other things, the ownership and operation of vessels used to carry passengers and cargo between points in the U.S. Subject to limited exceptions, the Jones Act requires that vessels engaged in the U.S. coastwise trade be built in the U.S., registered under the U.S.-flag, manned by predominantly U.S. crews and be owned and operated by “U.S. citizens” within the meaning of the Jones Act. Compliance with the Jones Act requires that non-U.S. citizens own no more than 25% in the entities that directly or indirectly own or operate the vessels that the Company operates in U.S. coastwise trade. Although SEACOR Marine’s Third Amended and Restated Certificate of Incorporation and Third Amended and Restated By-Laws contain provisions intended to assure compliance with these provisions of the Jones Act, a failure to maintain compliance could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects by, among other things (i) temporarily or permanently prohibiting the Company from operating vessels in the U.S. coastwise trade, (ii) subjecting the Company to fines and (iii) subjecting the Company’s vessels to seizure and forfeiture. Repeal, amendment, suspension or non-enforcement of the Jones Act would result in additional competition for the Company and could have a material adverse effect on the Company’s business. Substantial portions of the Company’s operations are conducted in the U.S. coastwise trade and thus subject to the provisions of the Jones Act (discussed above). For years, there have been attempts to repeal or amend such provisions, and such attempts are expected to continue in the future. Repeal, substantial amendment, waiver or substantial reinterpretation of provisions of the Jones Act could significantly adversely affect the Company by, among other things, resulting in additional competition from competitors with lower operating costs, because of their ability to use vessels built in lower-cost foreign shipyards, owned and manned by foreign nationals with promotional foreign tax incentives and with lower wages and benefits than U.S. citizens. In addition, the Company’s advantage as a U.S.-citizen operator of Jones Act vessels could be eroded by periodic efforts and attempts by foreign interests to circumvent certain aspects of the Jones Act. If maritime cabotage services were included in the General Agreement on Trade in Services or other international trade agreements, or if the restrictions contained in the Jones Act were otherwise altered, the shipping of maritime cargo between covered U.S. points could be opened to foreign-flag or foreign-built vessels. Because foreign vessels may have lower construction costs and operate at significantly lower costs than companies operating in the U.S. coastwise trade, such a change could significantly increase competition in the U.S. coastwise trade, which could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. 28 Restrictions on non-U.S. citizen ownership of the Company’s vessels could limit its ability to sell off any portion of its business or result in the forfeiture of its vessels. As noted above, compliance with the Jones Act requires that non-U.S. citizens own no more than 25% in the entities that directly or indirectly own or operate the vessels that the Company operates in the U.S. coastwise trade. If the Company were to seek to sell any portion of its business that owns any of these vessels, it may have fewer potential purchasers, since some potential purchasers might be unable or unwilling to satisfy the U.S. citizenship restrictions described above. As a result, the sales price for that portion of the Company’s business may not attain the amount that could be obtained through unconstrained bidding. Furthermore, if at any point the Company or any of the entities that directly or indirectly own its vessels cease to satisfy the requirements to be a U.S. citizen within the meaning of the Jones Act, the Company would become ineligible to operate in the U.S. coastwise trade and may become subject to penalties and risk forfeiture of its vessels. SEACOR Marine’s Third Amended and Restated Certificate of Incorporation and its Third Amended and Restated By-laws limit the ownership of Common Stock by individuals and entities that are not U.S. citizens within the meaning of the Jones Act. These restrictions may affect the liquidity of SEACOR Marine’s Common Stock and may result in non-U.S. citizens being required to sell their shares at a loss or relinquish their voting, dividend and distribution rights. Under the Jones Act, at least 75% of the outstanding shares of each class or series of SEACOR Marine’s capital stock must be owned and controlled by U.S. citizens within the meaning of the Jones Act. Certain provisions of SEACOR Marine’s Third Amended and Restated Certificate of Incorporation and its Third Amended and Restated By-Laws are intended to facilitate compliance with this requirement and may have an adverse effect on holders of shares of SEACOR Marine’s Common Stock. These restrictions may affect the liquidity of SEACOR Marine’s Common Stock. Under the provisions of SEACOR Marine’s Third Amended and Restated Certificate of Incorporation, the aggregate percentage of ownership by non-U.S. citizens of any class or series of SEACOR Marine’s capital stock is limited to 22.5% of the outstanding shares of each such class or series to ensure that such ownership by non-U.S. citizens will not exceed the maximum percentage permitted by the Jones Act, which is presently 25%. SEACOR Marine’s Third Amended and Restated Certificate of Incorporation also restricts ownership of shares of any class or series of its capital stock by a single non-U.S. citizen (and any other non-U.S. citizen whose ownership position would be aggregated with such non-U.S. citizen for purposes of the Jones Act) to not more than 4.9% of the outstanding shares of each such class or series. SEACOR Marine refers to such percentage limitations on ownership by persons who are not U.S. citizens within the meaning of the Jones Act as the “applicable permitted percentage.” SEACOR Marine’s Third Amended and Restated Certificate of Incorporation provides that any transfer or purported transfer of any shares of any class or series of its capital stock that would otherwise result in ownership (of record or beneficially) by non-U.S. citizens of shares of such class or series in excess of the applicable permitted percentage will be void and ineffective, and neither SEACOR Marine nor its transfer agent will register any such transfer or purported transfer in the Company records or recognize any such transferee or purported transferee as a stockholder of SEACOR Marine for any purpose (including for purposes of voting and dividends) except to the extent necessary to effect the remedies available to SEACOR Marine under its Third Amended and Restated Certificate of Incorporation. In the event such transfer restriction would be ineffective for any reason, SEACOR Marine’s Third Amended and Restated Certificate of Incorporation provides that if any transfer would otherwise result in ownership (of record or beneficially) by non-U.S. citizens of shares of such class or series in excess of the applicable permitted percentage, such transfer will cause such excess shares to be automatically transferred to a trust for the exclusive benefit of one or more charitable beneficiaries that are U.S. citizens within the meaning of the Jones Act. The proposed transferee will have no rights in the shares transferred to the trust, and the trustee, who will be a U.S. citizen chosen by SEACOR Marine and unaffiliated with SEACOR Marine or the proposed transferee, will have all voting, dividend and distribution rights associated with the shares held in the trust. The trustee will sell such excess shares to a U.S. citizen within 20 days of receiving notice from SEACOR Marine (or as soon thereafter as a sale may be effected in compliance with all applicable securities laws) and distribute to the proposed transferee the lesser of the price that the proposed transferee paid for such shares and the amount received from the sale, and any gain from the sale will be paid to the charitable beneficiary of the trust. These trust transfer provisions also apply to situations where ownership of a class or series of SEACOR Marine’s capital stock by non-U.S. citizens in excess of the applicable permitted percentage would result from a change in the status of a record or beneficial owner thereof from a U.S. citizen to a non-U.S. citizen or from a repurchase or redemption by SEACOR Marine of shares of its capital stock, in which case such person will receive the lesser of the market price of the shares on the date of such status change or such share repurchase or redemption and the amount received from the sale. As part of the foregoing trust transfer provisions, the trustee will be deemed to have offered the excess shares in the trust to the Company at a price per share equal to the lesser of (i) the market price on the date SEACOR Marine accepts the offer and (ii) the price per share in the purported transfer or original issuance of shares, as described in the preceding paragraph, or the market price per share on the date of the status change or share repurchase or redemption, that resulted in the transfer to the trust. 29 As a result of the above trust transfer provisions, a proposed transferee that is a non-U.S. citizen, or a record or beneficial owner whose citizenship status change results in excess shares, or whose shares become excess shares as a result of a repurchase or redemption by SEACOR Marine of its capital stock may not receive any return on its investment in shares it purportedly purchases or owns, as the case may be, and it may sustain a loss. To the extent that the above trust transfer provisions would be ineffective for any reason to prevent ownership (of record or beneficially) by non-U.S. citizens of the shares of any class or series of SEACOR Marine’s capital stock in excess of the applicable permitted percentage, SEACOR Marine’s Third Amended and Restated Certificate of Incorporation provides that SEACOR Marine, in its sole discretion, shall be entitled to redeem all or any portion of such excess shares most recently acquired (as determined by SEACOR Marine in accordance with guidelines that are set forth in its Third Amended and Restated Certificate of Incorporation), by non-U.S. citizens, or owned (of record or beneficially) by non-U.S. citizens as a result of a change in citizenship status or a repurchase or redemption by SEACOR Marine of shares of its capital stock, at a redemption price based on a fair market value formula that is set forth in SEACOR Marine’s Third Amended and Restated Certificate of Incorporation. The per share redemption price may be paid, as determined by the Board of Directors, by cash, promissory notes, warrants or a combination thereof. Such excess shares shall not be accorded any voting, dividend or distribution rights until they have ceased to be excess shares, provided that they have not been already redeemed by SEACOR Marine. As a result of the above provisions, a proposed transferee or owner of SEACOR Marine’s Common Stock that is a non-U.S. citizen may not receive any return on its investment in shares it purportedly purchases or owns, as the case may be, and it may sustain a loss. Further, SEACOR Marine may have to incur additional indebtedness, or use available cash (if any), to fund all or a portion of such redemption, in which case its financial condition may be materially weakened. So that SEACOR Marine may ensure its compliance with the Jones Act, its Third Amended and Restated Certificate of Incorporation permits SEACOR Marine to require that any record or beneficial owner of any shares of its capital stock provide SEACOR Marine with certain documentation concerning such owner’s citizenship. These provisions include a requirement that every person acquiring, directly or indirectly, five percent (5%) or more of the shares of any class or series of SEACOR Marine’s capital stock must provide SEACOR Marine with specified citizenship documentation. In the event that any person does not submit such requested or required documentation to SEACOR Marine, SEACOR Marine’s Third Amended and Restated Certificate of Incorporation provides it with certain remedies, including the suspension of the voting rights of such person's shares of SEACOR Marine’s capital stock and the payment of dividends and distributions with respect to those shares into an escrow account. As a result of non-compliance with these provisions, a record or beneficial owner of the shares of Common Stock may lose significant rights associated with those shares. In addition to the risks described above, the foregoing restrictions on ownership by non-U.S. citizens could delay, defer or prevent a transaction or change in control that might involve a premium price for SEACOR Marine’s Common Stock or otherwise be in the best interest of its stockholders. The Company could be forced to suspend its operations in the U.S. coastwise trade if the provisions in its organizational documents fail to prevent a violation of the Jones Act. SEACOR Marine’s Third Amended and Restated Certificate of Incorporation and its Third Amended and Restated By-Laws contain provisions prohibiting ownership of its Common Stock by persons who are not U.S. citizens within the meaning of the Jones Act, in the aggregate, in excess of 22.5% of such shares, in order to ensure that such ownership by non-U.S. citizens will not exceed the maximum percentage permitted by the Jones Act, which is presently 25%. SEACOR Marine’s Third Amended and Restated Certificate of Incorporation and its Third Amended and Restated By-Laws permit SEACOR Marine to redeem such excess shares in the event that the transfer of such excess shares to a trust for sale would be ineffective. The per share redemption price may be paid, as determined by the Board of Directors, by cash, promissory notes or warrants. However, SEACOR Marine may not be able to redeem such excess shares for cash because its operations may not have generated sufficient excess cash flow to fund such redemption. If, for any reason, SEACOR Marine is unable to effect such a redemption when such ownership of shares by non-U.S. citizens is in excess of 25% of the Common Stock, or otherwise prevent non-U.S. citizens in the aggregate from owning shares in excess of 25% of any such class or series of its capital stock, or fail to exercise its redemption rights because it is unaware that such ownership exceeds such percentage, SEACOR Marine will likely be unable to comply with the Jones Act and will likely be required by the applicable governmental authorities to suspend its operations in the U.S. coastwise trade. Any such actions by governmental authorities would likely have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. Under certain circumstances, the Company’s vessels are subject to requisition for ownership or use by governmental agencies. The Merchant Marine Act provides that, during a national emergency declared by presidential proclamation or a period for which the U.S. President has proclaimed that the security of the national defense makes it advisable, the Secretary of Transportation may requisition the ownership or use of any vessel owned by U.S. citizens (which includes the Company) and any vessel under construction in the U.S. If any of the Company’s vessels were purchased or chartered by the federal government under this law, the Company would be entitled to just compensation, which is generally the fair market value of the vessel in the case of a purchase or, in the case of a charter, the fair market value of charter hire, but the Company would not be entitled to compensation for any consequential damages it may suffer. The purchase or charter for an extended period of time by the federal government of one or more of the Company’s vessels under this law could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. Vessels registered under other flag states may also be subject to requisition or purchase in accordance with applicable local law. 30 The Company may not be able to sell vessels to improve its liquidity because it may be unable to locate buyers with access to financing or to complete any sales on acceptable terms or within a reasonable time frame. The Company may seek to sell some of its vessels to provide liquidity. However, given the volatility in the oil and natural gas industry in general, and the offshore oil and natural gas industry in particular, there may not be sufficient activity in the market to sell the Company’s vessels and the Company may not be able to identify buyers with access to financing or to complete any such sales. Even if the Company is able to locate appropriate buyers for its vessels, any sales may occur on less favorable terms than the terms that might be available in a more liquid market or at other times in the business cycle. In addition, the terms of the Company’s current and future indebtedness may limit its ability to sell assets, including vessels, or require that it use the proceeds from any such sale in a specified manner. The Company may be unable to collect amounts owed to it by its customers. The Company typically grants its customers credit on a short-term basis. Related credit risks are inherent as the Company does not typically collateralize receivables due from customers and the Company’s ten largest customers accounted for approximately 73% of the consolidated revenues from continuing operations in 2023. In addition, many of its international customers are state-controlled and, as a result, the Company’s receivables may be subject to local political priorities, which are out of the Company’s control. The Company provides estimates for uncollectible accounts based primarily on its judgment using historical losses, current economic conditions and individual evaluations of each customer as evidence supporting the receivables valuations stated on the Company’s financial statements. However, the Company’s receivables valuation estimates may not be accurate and receivables due from customers reflected in its financial statements may not be paid in a timely manner or collectible. The Company’s inability to perform under its contractual obligations, or its customers’ inability or unwillingness to fulfill their contractual commitments to the Company, may have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company participates in joint ventures, and its investments in joint ventures could be adversely affected by its lack of sole decision-making authority and disputes between its partners and itself. The Company participates in domestic and international joint ventures to further expand its capabilities, share risks and gain access to local markets. Due to the nature of joint venture arrangements, the Company does not unilaterally control the operating, strategic and financial policies of these business ventures. Decisions are often made on a collective basis, including the purchase and sale of assets, charter arrangements with customers and management of cash, including cash distributions to partners. In addition, joint ventures can often require unanimous approval of the parties to the joint venture or their representatives for certain fundamental decisions, which could lead to deadlock in the operations or strategy with respect to the joint venture or partnership. Decisions made by the managers or the governing bodies of these entities may not always be the decision that is most beneficial to the Company as one of the equity holders of the entity, may be contrary to the Company’s objectives, and may limit the Company’s ability to transfer its interests. Investments in joint ventures involve risks that would not be present were a third party not involved, including the possibility that the Company’s co-ventures might become bankrupt or fail to fund their share of required capital contributions. Any failure of such other companies to meet their obligations to the Company or to third parties, or any disputes with respect to the parties’ respective rights and obligations, could have a material adverse effect on the joint ventures or their properties and, in turn, could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company’s participation in industry-wide, multi-employer, defined benefit pension plans expose it to potential future losses. Certain of the Company’s subsidiaries are participating employers in two industry-wide, multi-employer defined benefit pension plans in the U.K., namely, the U.K. Merchant Navy Officers Pension Fund (“MNOPF”) and the U.K. Merchant Navy Ratings Pension Fund (“MNRPF”). Among other risks associated with multi-employer plans, contributions and unfunded obligations of the multi-employer plan are shared by the plan participants. As a result, the Company may inherit unfunded obligations if other plan participants withdraw from the plan or cease to participate, and in the event that the Company withdraws from participation in one or both of these plans, it may be required to pay the plan an amount based on its allocable share of the underfunded status of the plan. Depending on the results of future actuarial valuations, it is possible that the plans could experience further deficits that will require funding from the Company, which would negatively impact its financial position, results of operations and cash flows. For example, on October 19, 2021, the Company was informed by the MNRPF that two issues had been identified during a review of the MNRPF by the applicable trustee that would potentially give rise to material additional liabilities for the MNRPF. On November 23, 2023, the trustee advised that following the tri-annual valuation, $1.5 million (£1.2 million) of the potential cumulative funding deficit of the MNRPF was allocated to the Company as a participating employer, including the additional liabilities mentioned above. During 2023, the Company recognized payroll related operating expenses of $1.5 million (£1.2 million) for its allocated share of the potential cumulative funding deficit, which the Company will be invoiced for during 2024 and 2025. 31 The Company’s employees are covered by federal laws that may subject it to job-related claims in addition to those provided by state laws. Some of the Company’s employees are covered by provisions of the Jones Act, the Death on the High Seas Act and general maritime law. These laws preempt state workers’ compensation laws and permit these employees and their representatives to pursue actions against employers for job-related incidents in federal courts based on tort theories. Because the Company is not generally protected by the damage limits imposed by state workers’ compensation statutes for these types of claims, it may have greater exposure for any claims made by these employees. Risk Factors Related to the Company’s Common Stock The Company’s stock price may fluctuate significantly, and investors may not be able to sell their shares at an attractive price. The trading price of the Company’s Common Stock may be volatile and subject to wide price fluctuations in response to various factors including: • market conditions in the broader stock market; • • • • • • • • • • • • the Company’s capital structure and liquidity; commodity prices and in particular prices of oil and natural gas; actual or anticipated fluctuations in the Company’s quarterly financial condition and results of operations; introduction of new equipment or services by the Company or its competitors; issuance of new or changed securities analysts’ reports or recommendations; purchases and sales of large blocks of the Company’s Common Stock and the frequency and volume with which the Common Stock trades on the New York Stock Exchange (“NYSE”); additions or departures of key personnel; the ability or willingness of OPEC to set and maintain production levels for oil; oil and natural gas production levels by non-OPEC countries; regulatory or political developments; litigation and governmental investigations; and changing economic conditions. These and other factors may cause the market price and demand for the Company’s Common Stock to fluctuate substantially, which may limit or prevent investors from readily selling their shares of the Company’s Common Stock and may otherwise negatively affect the liquidity of the Company’s Common Stock. In addition, in the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the company that issued the stock. If any of the Company’s stockholders were to bring a lawsuit against it, the Company could incur substantial costs defending the lawsuit. Such a lawsuit could also divert the time and attention of the Company’s management from its business. An investor’s percentage of ownership in the Company may be diluted in the future as result of warrant exercise, the issuance of equity incentive awards, and sales of Common Stock, including pursuant to the Company’s ATM Program. As with any publicly traded company, an investor’s percentage ownership in the Company may be diluted in the future because of equity issuances for acquisitions, capital market transactions or otherwise, including equity awards that the Company has and will continue to grant to its directors, officers and employees. For instance, among other prior issuances of the Company’s Common Stock, in December 2021, the Company issued 1,567,935 shares of Common Stock as merger and related consideration to purchase the remaining equity and subordinated debt interests in SEACOR OSV Partners I LP, a Delaware limited partnership (“OSV Partners I”), that the Company did not already own. In November of 2023, the Company entered into an at-the-market offering program (“ATM Program”) with B. Riley Securities, Inc. under which the Company may sell up $25.0 million of Common Stock from time to time. As of December 31, 2023, remaining capacity under the ATM Program was approximately $24.9 million. 32 In addition, an investor’s percentage ownership in the Company will be diluted if any of the holders of the New Convertible Notes exercise their right to convert the principal amount of their outstanding notes, in whole or in part, into shares of Common Stock or if holders the Company’s outstanding warrants exercise their warrants. Holders of the New Convertible Notes are entitled to convert the principal amount of their outstanding notes into shares of Common Stock (or, if required to maintain Jones Act compliance, warrants to purchase such stock for $0.01) at a conversion rate of 85.1064 shares of Common Stock per $1,000 principal amount of the New Convertible Notes through July 1, 2026. Similarly, the Company has outstanding warrants to purchase 1,304,333 shares of Common Stock, which if exercised would dilute the ownership percentage of the Company’s shareholders. If securities or industry analysts do not publish research or reports about the Company’s business, if they adversely change their recommendations regarding the Company’s stock or if the Company’s results of operations do not meet their expectations, the Company’s stock price and trading volume could decline. The trading market for the Company’s Common Stock is influenced by the research and reports that industry or securities analysts publish about the Company or its business. If one or more of these analysts cease coverage of the Company or fail to publish reports on the Company regularly, the Company could lose visibility in the financial markets, which in turn could cause its stock price or trading volume to decline. Moreover, if one or more of the analysts who cover the Company downgrade recommendations regarding the Company’s stock, or if the Company’s results of operations do not meet their expectations, the Company’s stock price could decline and such decline could be material. The Company is obligated to develop and maintain proper and effective internal control over financial reporting and is subject to other requirements that will be burdensome and costly. The Company is subject to other reporting and corporate governance requirements, including the requirements of the NYSE, and certain provisions of the Sarbanes-Oxley Act and the regulations promulgated thereunder, which impose significant compliance obligations upon the Company. As a public company, the Company is required to: • • • • • • • • • prepare and distribute periodic public reports and other stockholder communications in compliance with its obligations under the federal securities laws and NYSE rules; create or expand the roles and duties of its board of directors and committees of the board of directors; institute more comprehensive financial reporting and disclosure compliance functions; supplement its internal accounting and auditing function, including hiring additional staff with expertise in accounting and financial reporting for a public company; enhance and formalize closing procedures at the end of the Company’s accounting periods; enhance the Company’s internal audit function; enhance the Company’s investor relations function; establish new internal policies, including those relating to disclosure controls and procedures; and involve and retain to a greater degree outside counsel and accountants in the activities listed above. These changes require a significant commitment of additional resources, including increased auditing and legal fees and costs associated with hiring additional accounting and administrative staff. The Company may not be successful in fully and efficiently implementing these requirements and implementing them could materially adversely affect its business, financial position, results of operations, cash flows and prospects. Failure to achieve and maintain effective internal controls over financial reporting in accordance with Section 404 could have a material adverse effect on the Company. Section 404 of the Sarbanes-Oxley Act (“Section 404”) requires the Company to establish effective internal controls over financial reporting and disclosure controls and procedures pursuant to Section 404 and management and its auditors to assess the effectiveness of such controls. 33 If the Company is unable to maintain adequate internal control over financial reporting, it may be unable to report its financial information on a timely basis, may violate applicable stock exchange listing rules or suffer other adverse regulatory consequences and may breach the covenants under its credit facilities. There could also be a negative reaction in the price of the Company’s Common Stock due to a loss of investor confidence in the Company and the reliability of its financial statements. It cannot be assumed that the Company will not have a material weakness in its internal controls over financial reporting in the future. Moreover, the Company’s internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the possibility of human error, the circumvention or overriding of controls or fraud. Even effective internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of financial statements. The existence of a material weakness could result in errors in the Company’s financial statements that could result in a restatement of financial statements, which could cause the Company to fail to meet its reporting obligations, lead to a loss of investor confidence and have a negative impact on the trading price of the Company’s Common Stock. Provisions in SEACOR Marine’s Third Amended and Restated Certificate of Incorporation and Third Amended and Restated By- Laws, and Delaware law may discourage, delay or prevent a change of control of SEACOR Marine or changes in SEACOR Marine’s management and, therefore, may depress the trading price of its Common Stock. SEACOR Marine’s Third Amended and Restated Certificate of Incorporation and Third Amended and Restated By-Laws include certain provisions that could have the effect of discouraging, delaying or preventing a change of control of SEACOR Marine or changes in its management, including, among other things: • • • • • restrictions on the ability of SEACOR Marine’s stockholders to fill a vacancy on the Board of Directors; restrictions related to the ability of non-U.S. citizens owning SEACOR Marine’s Common Stock; SEACOR Marine’s ability to issue preferred stock with terms that the Board of Directors may determine, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer; the absence of cumulative voting in the election of directors which may limit the ability of minority stockholders to elect directors; and advance notice requirements for stockholder proposals and nominations, which may discourage or deter a potential acquirer from soliciting proxies to elect a particular slate of directors or otherwise attempting to obtain control of SEACOR Marine. These provisions in SEACOR Marine’s Third Amended and Restated Certificate of Incorporation and Third Amended and Restated By-Laws may discourage, delay or prevent a transaction involving a change in control of SEACOR Marine that is in the best interest of its stockholders. Even in the absence of a takeover attempt, the existence of these provisions may adversely affect the prevailing market price of SEACOR Marine’s Common Stock if they are viewed as discouraging future takeover attempts. SEACOR Marine’s Third Amended and Restated By-Laws include a forum selection clause, which could limit SEACOR Marine’s stockholders’ ability to obtain a favorable judicial forum for disputes with SEACOR Marine. SEACOR Marine’s Third Amended and Restated By-Laws require that, unless SEACOR Marine consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of SEACOR Marine, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of SEACOR Marine to SEACOR Marine or SEACOR Marine’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, or (iv) any action asserting a claim governed by the internal affairs doctrine. 34 This exclusive forum provision will not apply to claims under the Exchange Act, but will apply to other state and federal law claims including actions arising under the Securities Act of 1933 (although SEACOR Marine’s stockholders will not be deemed to have waived SEACOR Marine’s compliance with the federal securities laws and the rules and regulations thereunder). Section 22 of the Securities Act of 1933, however, creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act of 1933 or the rules and regulations thereunder. Accordingly, there is uncertainty as to whether a court would enforce such a forum selection provision as written in connection with claims arising under the Securities Act of 1933. Any person or entity purchasing or otherwise acquiring any interest in shares of SEACOR Marine’s capital stock is deemed to have notice of and consented to the foregoing provisions. This forum selection provision in SEACOR Marine’s Third Amended and Restated By- Laws may limit SEACOR Marine’s stockholders’ ability to obtain a favorable judicial forum for disputes with SEACOR Marine. It is also possible that, notwithstanding the forum selection clause included in SEACOR Marine’s Third Amended and Restated By-Laws, a court could rule that such a provision is inapplicable or unenforceable. SEACOR Marine does not expect to pay dividends to holders of its Common Stock. SEACOR Marine currently intends to retain its future earnings, if any, for the foreseeable future, to repay indebtedness and to fund the development and growth of its business. SEACOR Marine does not intend to pay any dividends to holders of its Common Stock. As a result, capital appreciation in the price of SEACOR Marine’s Common Stock, if any, will be investor's only source of gain or income on an investment in SEACOR Marine’s Common Stock. General Risk Factors Difficult economic conditions and volatility in the capital markets could materially adversely affect the Company. The success of the Company’s business is both directly and indirectly dependent upon conditions in the global financial markets and economic conditions in the U.S. and throughout the world that are outside the Company’s control and are difficult to predict. Factors such as global and/or regional conflicts, such as the conflict between Russia and Ukraine and the hostilities in the Middle East, pandemic responses, commodity prices and demand for commodities, interest rates, availability of credit, inflation rates, changes in laws (including laws relating to taxation), trade barriers, currency exchange rates and controls, significant economic downturns or recessions and national and international political circumstances (including wars, terrorist acts, security operations or pandemics) can have a material negative impact on the Company’s business and investments, which could reduce its revenues and profitability. Uncertainty about global economic conditions may cause or require businesses to postpone capital spending in response to tighter credit and reductions in income or asset values and to cancel or renegotiate existing contracts because their access to capital is impeded. This would in turn affect the Company’s profitability or results of operations. These factors may also adversely affect the Company’s liquidity and financial condition and the liquidity and financial conditions of its customers. Volatility in the conditions of the global economic markets can also affect the Company’s ability to raise capital at attractive prices. The Company’s ongoing exposure to credit risks on its accounts receivable balances are heightened during periods when economic conditions worsen. The Company has procedures that are designed to monitor and limit exposure to credit risk on its receivables, however, there can be no assurance that such procedures will effectively limit the Company’s credit risk and avoid losses that could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. Unstable economic conditions, including an economic downturn or recession may also increase the volatility of the Company’s stock price. An economic downturn and related economic uncertainty may have a negative impact on the Company’s business. The Company’s operations are subject to certain foreign currency, interest rate, fixed-income, equity and commodity price risks. The Company is exposed to certain foreign currency, interest rate, fixed-income, equity and commodity price risks and, although some of these risks may be hedged, fluctuations could impact its financial position and its results of operations. The Company has, and anticipates that it will continue to have, contracts denominated in foreign currencies. It is often not practicable for the Company to effectively hedge the entire risk of significant changes in currency rates during a contract period. The Company’s financial position, results of operations and cash flows have been negatively impacted for certain periods and positively impacted for other periods, and may continue to be affected to a material extent by the impact of foreign currency exchange rate fluctuations. For example, strengthening of the U.S. dollar could give rise to reduced prices from shipyards and incentivize additional investment in new equipment notwithstanding the current state of such market. The Company’s financial position, results of operations and cash flows may also be affected by the cost of hedging activities that it undertakes. Volatility in the financial markets and overall economic uncertainty also increase the risk that the actual amounts realized in the future on the Company’s debt and equity instruments could differ significantly from the fair values currently assigned to them. In addition, changes in interest rates may have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. Specifically, rising interest rates, including a potential rapid rise in interest rates, could increase the Company’s cost of capital. There can be no assurance that the Company will be able to access the capital markets to provide funding for future operations that would require additional capital beyond the Company’s current existing available capital on terms acceptable or favorable to the Company. 35 The Company engages in hedging activities which exposes it to risks. For corporate purposes, the Company has in the past and may in the future use futures and swaps to hedge risks, such as escalation in fuel costs and movements in foreign exchange rates and interest rates. Such activities can themselves result in losses when a position is purchased in a declining market or a position is sold in a rising market. The Company may also purchase inventory in larger than usual levels to lock in costs when it believes there may be large increases in the price of raw materials or other material used in its business. Such purchases expose the Company to risks of meeting margin calls and drawing on its capital, counter-party risk due to failure of an exchange or institution with which it has entered into a swap, incurring higher costs than competitors or similar businesses that do not engage in such strategies, and losses on its investment portfolio. Such strategies can also cause earnings to be volatile. If the Company fails to offset such volatility, this could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. The Company’s results could be impacted by U.S. social, political, regulatory and economic conditions as well as by changes in tariffs, trade agreements or other trade restrictions imposed by the U.S. government. Changes in U.S. political, regulatory and economic conditions or in laws and policies governing foreign trade (including the U.S. trade agreements and U.S. tariff policies), travel to and from the U.S., immigration, manufacturing, development and investment in the territories and countries in which the Company operates, and any negative sentiments or retaliatory actions towards the U.S. as a result of such changes, could adversely affect the global marine and support transportation services industry. Changes in U.S. foreign policy could create uncertainty about future relationships between the U.S. and other countries, including with respect to trade policies, treaties, government regulations and tariffs. Changes in these policies may have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. A violation of the Foreign Corrupt Practices Act of 1977 (“FCPA”) or similar worldwide anti-bribery laws may adversely affect the Company’s business and operations. In order to effectively compete in certain foreign jurisdictions, the Company seeks to establish joint ventures with local operators or strategic partners. As a U.S. corporation, the Company is subject to the regulations imposed by the FCPA, which generally prohibits U.S. companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or maintaining business. The Company has stringent policies and procedures in place to enforce compliance with the FCPA. Nevertheless, the Company does business and may do additional business in the future in countries and regions where strict compliance with anti- bribery laws may not be customary and the Company may be held liable for actions taken by its strategic or local partners even though these partners may not be subject to the FCPA. The Company’s personnel and intermediaries, including its local operators and strategic partners, may face, directly or indirectly, corrupt demands by government officials, political parties and officials, tribal or insurgent organizations, or private entities in the countries in which it operates or may operate in the future. As a result, the Company faces the risk that an unauthorized payment or offer of payment could be made by one of its employees or intermediaries, even if such parties are not always subject to the Company’s control or are not themselves subject to the FCPA or other similar laws to which the Company may be subject. Any allegation or determination that the Company has violated the FCPA (or any other applicable anti-bribery laws in countries in which the Company does business, including the U.K. Bribery Act 2010) could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. Adverse results of legal proceedings could materially adversely affect the Company. The Company is subject to and may in the future be subject to a variety of legal proceedings and claims that arise out of the ordinary conduct of its business. Results of legal proceedings cannot be predicted with certainty. Irrespective of its merits, litigation may be both lengthy and disruptive to the Company’s operations and may cause significant expenditure and diversion of management attention. The Company may be faced with significant monetary damages or injunctive relief against it that which could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects should it fail to prevail in certain matters. 36 Negative publicity may adversely impact the Company. The Company’s operations involve the risk of incidents and media coverage thereof. Such incidents include, but are not limited to, the improper operation or maintenance of vessels; crew illnesses; mechanical failures, fires and collisions; repair delays, groundings and navigational errors; oil spills and other maritime and environmental issues as well as other incidents at sea, which may generate negative publicity or cause crew discomfort, injury, or death. Although the Company’s commitment to the safety of its employees is paramount to the success of the Company’s business, the Company’s vessels have been involved in accidents and other incidents in the past and the Company may experience similar or other incidents in the future. The Company’s ability to attract and retain its clients, hire and retain employees and the amounts the Company must pay its employees depend, in part, upon the perception and reputation of the Company. Media coverage and public statements that insinuate improper actions by the Company, regardless of their factual accuracy or truthfulness, may result in negative publicity, litigation or governmental investigations by regulators. Addressing negative publicity and any resulting litigation or investigations may distract management, increase costs and divert resources. Negative publicity may have an adverse impact on the Company’s reputation and the morale of its employees, which could materially adversely affect its business, financial position, results of operations, cash flows and prospects. Changes or modifications in financial account standards or practices may cause an adverse impact on reported results of operations or financial conditions. The accounting rules and regulations that the Company complies with are subject to interpretation by the Financial Accounting Standards Board, the SEC and other various bodies formed to promulgate and interpret appropriate accounting principles. A change or modification in accounting standards or practices may have a significant effect on the Company’s reported results of operations and the way that the Company conducts its business. The accounting rules and regulations and their interpretations have changed in the past and may change in the future. The Company cannot predict the impact that future changes to existing regulations or the introduction of new accounting rules or regulations might have on the Company’s business. The Company’s success depends on key members of its management, the loss of whom could disrupt its business operations. The Company depends to a large extent on the efforts and continued employment of its executive officers and key management personnel. It does not maintain key-man insurance. The loss of services of one or more of its executive officers or key management personnel could have a material adverse effect on the Company’s business, financial position, results of operations, cash flows and prospects. 37 ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 1C. CYBERSECURITY The Company relies on technology infrastructure and information systems, including the Internet and cloud services, to process, transmit and store electronic and financial information, manage a variety of business processes and activities, and comply with regulatory, legal and tax requirements. The Company also depends on its information technology infrastructure to capture knowledge of its business including its vessel operation systems, which contain information about vessel positioning and scheduling; monitor its vessel maintenance and engine systems; coordinate its business across its bases of operation including cargo delivery and equipment tracking; and communicate within its organization and with customers, suppliers, partners and other third parties. The Company’s ability to service customers and operate vessels is dependent on the continued operation of these systems. While the Company takes various precautions and has enhanced controls around its systems, like other technology systems, they are susceptible to damage, disruptions or shutdowns, hardware or software failures, power outages, computer viruses, telecommunication failures, user errors, catastrophic events, or cyber-attacks including malware, other malicious software, phishing email attacks, attempts to gain unauthorized access to its data, the unauthorized release, corruption or loss of its data, loss or damage to its data delivery systems, ransomware, and other electronic security breaches. Over time, these attacks have become increasingly sophisticated and, in some cases, have been conducted or sponsored by “nation state” operators. The Company expects that sophistication of cyber-threats will continue to evolve as threat actors increase their use of AI and machine-learning technologies. Many threat actors are well funded. The Company has implemented robust processes to assess, identify, and manage cybersecurity risks, including potentially material risks, related to the Company’s internal information systems and its services. The Board of Directors has direct oversight of the Company’s risk management process and the management of cybersecurity risks. Under the direction and supervision of the Company’s Chief Financial Officer, the Company conducts periodic risk assessments, which include cybersecurity risks. Senior management meets with the Board of Directors to review and discuss risk management on an annual basis. Management will provide a comprehensive update to the Board of Directors on cybersecurity threats and risk mitigation at least annually, and more frequently as relevant. The Company’s Director of Technology, reporting to the Chief Financial Officer, has principal responsibility for assessing and managing cybersecurity risks and threats, implementing the systems necessary to address such risks and threats, and preparing updates for the Board of Directors. The Director of Technology has a combined twenty-one years of experience leading and working on cybersecurity teams at the Company and other companies in the oil and natural gas industry, has significant experience with networking, on-premises and cloud-based infrastructure, and cybersecurity controls, and has a Bachelor of Science degree. In response to the increasing threats presented by cyber incidents, in April 2022 the Company established a Cybersecurity Committee, which meets regularly. This committee is comprised of the Director of Technology, members of management from the technology, quality, health, safety and environment and operations departments, as well as the Chief Financial Officer and the General Counsel, both of whom report to the Chief Executive Officer. The Cybersecurity Committee oversees activities related to the monitoring, prevention, detection, mitigation and remediation of cybersecurity risks. The Cybersecurity Committee develops and implements cybersecurity risk mitigation strategies and activities throughout the year, including the management of comprehensive incident response plans, oversees the cybersecurity risks posed by third-party vendors and receives regular updates on cybersecurity-related matters. The Company has adopted the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework to continuously evaluate and enhance its cybersecurity procedures. Activities include mandatory quarterly online training for all employees, technical security controls, enhanced data protection, the maintenance of backup and protective systems, policy review and implementation, periodic assessments of third-party service providers to assess cyber preparedness of key vendors, and running simulated cybersecurity drills, including vulnerability scanning, penetration testing and disaster recovery exercises, throughout the organization. These cybersecurity drills are performed both in-house and by third-party service providers. The Company uses automated tools that monitor, detect, and prevent cybersecurity risks that are monitored by the technology department and a third-party vendor. As noted above, the Cybersecurity Committee is also implementing comprehensive incident response plans that outline the appropriate communication flow and response for certain categories of potential cybersecurity incidents. The Cybersecurity Committee escalates events, including to the Chief Executive Officer and Board of Directors, as relevant, based on the materiality of the event. When the Company experiences a cybersecurity incident, the Director of Technology will inform the Cybersecurity Committee, which will then evaluate and assess the materiality of the incident to the Company, its information technology infrastructure and data integrity, and, in particular, whether the cybersecurity incident should be reported to the Board of Directors in advance of or external to the next regular cybersecurity update. Once a cybersecurity incident is reported to the Board of Directors, the Board of Directors provides oversight of the Company’s response to such incident. The Cybersecurity Committee continuously monitors incidents as they are remedied to ensure proper remediation and, if necessary, the ability to report to the Board of Directors if previously unknown material information arises during such remediation. 38 The Company engages subject matter experts such as consultants and auditors to assist us in establishing processes to assess, identify, and manage potential and actual cybersecurity threats, to actively monitor the Company’s systems internally using widely accepted digital applications, processes, and controls, and to provide forensic assistance to facilitate system recovery in the case of an incident. The Cybersecurity Committee oversees and establishes the parameters of the Company’s engagement with these experts to ensure the Company obtains the supplemental assistance needed in this area, if any. The Company’s information technology systems are in some cases integrated, such that damage, disruption or shutdown to one system could result in a more widespread impact on the Company’s systems as a whole. If the Company’s information technology systems suffer severe damage, disruption or shutdown, and its business continuity plans do not effectively resolve the issues in a timely manner, the Company’s business could be negatively affected. In addition, cyber-attacks could lead to potential unauthorized access and disclosure of confidential information, data loss and corruption (see “Item 1A. Risk Factors” under the heading “The Company relies on information technology, and if it is unable to protect against service interruptions, data corruption, cyber-based attacks or network security breaches, its operations could be disrupted and its business could be negatively affected” of this Annual Report on Form 10-K. A cybersecurity incident could materially harm the Company’s reputation and financial condition and cause us to incur legal liability and increased costs to respond to such events. ITEM 2. PROPERTIES Offshore support vessels are the principal physical properties owned by the Company as more fully described in “Item 1. Business” of this Annual Report on Form 10-K. ITEM 3. LEGAL PROCEEDINGS In the normal course of its business, the Company becomes involved in various litigation matters including, among others, claims by third parties for alleged property damages and personal injuries. In the opinion of the Company's management, while the outcome of these matters is uncertain, the likely results of these matters are not expected, either individually or in the aggregate, to have a material adverse effect on the Company's financial position, results of operations or cash flows. However, 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 such changes in estimated costs would have a material adverse effect on the Company’s business, consolidated financial position, results of operations, cash flows and prospects.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) below presents the Company’s operating results for each of the three years in the period ended December 31, 2023, and its financial condition as of December 31, 2023 and 2022. Certain statements in this MD&A constitute forward looking statements. See “Forward Looking Statements” included elsewhere in this Annual Report on Form 10-K. The following MD&A is intended to help the reader understand the results of operations and financial condition of the Company. The MD&A is provided as a supplement to, and should be read in conjunction with, the consolidated financial statements and related notes included in Part IV of this Annual Report on Form 10-K and incorporated herein by reference. Overview The Company provides global marine and support transportation services to offshore energy facilities worldwide. As of December 31, 2023, the Company operated a diverse fleet of 58 support vessels, of which 55 were owned or leased-in and three were managed on behalf of unaffiliated third parties. 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, (iv) carry and launch equipment used underwater in drilling and well installation, maintenance, inspection and repair and (v) handle anchors and mooring equipment for offshore rigs and platforms. Additionally, the Company’s vessels provide emergency response services and accommodations for technicians and specialists. Recent Developments At the Market Program On November 1, 2023, SEACOR Marine entered into an at-the-market sales agreement (the “Sales Agreement”) with B. Riley Securities, Inc. (the “Sales Agent”), relating to the potential issuance and sale from time to time by SEACOR Marine of shares of SEACOR Marine’s common stock, par value $0.01 per share (the “Common Stock”) having an aggregate gross sales price of up to $25.0 million. During the fourth quarter of 2023, SEACOR Marine sold 7,674 shares of Common Stock at an average price of $13.1891 per share for total gross proceeds to the Company of $101,213 leaving us with approximately $24.9 million of additional capacity under the ATM Program. Debt Refinancing and Maturity Extension In September 2023, SEACOR Marine, as parent guarantor, SMFH, as borrower, and certain other wholly-owned subsidiaries of SEACOR Marine, as subsidiary guarantors, entered into a $122.0 million senior secured term loan (the “2023 SMFH Credit Facility”) with certain affiliates of EnTrust Global, as lenders, Kroll Agency Services, Limited, as facility agent, and Kroll Trustee Services Limited, as security trustee. The proceeds of the 2023 SMFH Credit Facility were used to, among other things, refinance approximately $104.8 million of indebtedness under five separate credit and ship financing facilities. As a result, the new maturity of the debt refinanced is September 2028. In addition, in June 2023 the Company refinanced shipyard financing provided by COSCO Shipping Heavy Industry (Zhoushan) Co. incurred in connection with the delivery of three platform supply vessels during 2019 and 2020 with the proceeds of a $28.0 million senior secured term loan facility entered into by SEACOR Alps LLC, SEACOR Andes LLC, and SEACOR Atlas LLC, each a wholly-owned subsidiary of SEACOR Marine, as borrowers. As a result, the new maturity of the debt refinanced is June 2028. 43 Trends Affecting the Offshore Marine Business Oil and Natural Gas Prices The market for offshore oil and natural gas drilling has historically been cyclical. Demand for offshore support vessels is highly correlated to the price of oil and natural gas as those prices significantly impact the Company’s customers’ exploration and drilling activity levels. Oil and natural gas prices tend to fluctuate based on many factors, including global economic activity, levels of reserves and production activity. Price levels for oil and natural gas have and will continue to influence demand for offshore marine services. In addition to the price of oil and natural gas, the availability of acreage, local tax incentives or disincentives, in significant oil and natural gas producing regions, drilling moratoriums and other regulatory actions, and requirements for maintaining interests in leases affect activity in the offshore oil and natural gas industry. Factors that influence the level of offshore exploration and drilling activities include: • • • • expectations as to future oil and natural gas commodity prices; customer assessments of offshore drilling prospects compared with land-based opportunities, including newer or unconventional opportunities such as shale; expectations as to the future demand for oil and natural gas in the context of the transition to non-hydrocarbon based sources of energy; customer assessments of cost, geological opportunity and political stability in host countries; • worldwide demand for oil and natural gas; • the ability or willingness of OPEC to set and maintain production levels and pricing; • military conflicts and terrorism in oil producing regions, including the Middle East and Russia; • • • • the level of oil and natural gas production by non-OPEC countries; transitions to and demand for non-hydrocarbon based energy sources; the relative exchange rates for the U.S. dollar; and various U.S. and international government policies regarding exploration and development of oil and natural gas reserves. Offshore oil and natural gas market conditions are highly volatile. 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 at points during 2022 primarily as a result of the conflict between Russia and Ukraine as well as the related economic sanctions and economic uncertainty. During 2023, WTI oil prices reached a high of $94 per barrel and a low of $67 per barrel, ending the year in the $72 per barrel range. While the Company has experienced difficult market conditions over the past few years due to low and volatile oil and natural gas prices and the focus of oil and natural gas producing companies on cost and capital spending budget reductions, 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 potential new charters. Vessel Supply Dynamics and Other Industry Drivers 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 lowering 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. 44 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 farms support as the industry grows. While the Company expects that alternative forms of energy will continue to grow and add to the world’s energy mix, especially as 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 electricity from natural gas. Some alternative forms of energy such as offshore wind farms support some of the Company’s businesses and the Company expects such support to increase as development 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 inspections and related docking 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 December 31, 2023, three of the Company’s 55 owned and leased-in vessels were cold- stacked worldwide, including one vessel classified as held for sale. Inflation The Company’s operations expose it to the effects of inflation. Inflation has become a significant factor in the world economy post-pandemic and has led to an increased interest rate environment as well as inflationary pressures on the Company's operations, including but not limited to increased labor, repairs and maintenance, transportation and insurance costs. Certain Components of Revenues and Expenses The Company operates its fleet in four principal geographic regions: the U.S., primarily in the Gulf of Mexico; Africa and Europe; the Middle East and Asia; and Latin America, primarily in Mexico and Guyana. 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. 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. Time charter statistics are the key performance indicators for the Company’s time charter revenues. The rate per day worked is the ratio of total time charter revenues to the aggregate number of days worked. Utilization is the ratio of aggregate number of days worked to total available days for all vessels available for time charter. Unless vessels have been retired and removed from service, available days represents the total calendar days for which vessels available for time charter were owned or leased-in by the Company, whether marketed, under repair, cold-stacked or otherwise out-of-service. Operating Revenues. The Company generates revenues by providing services to customers primarily pursuant to two different types of contractual arrangements: time charters and bareboat charters. 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 all risks of operation. Vessel charters may range from several days to several years. Direct Operating Expenses. The aggregate cost of operating the Company’s fleet depends primarily on the size and asset mix of the fleet. The Company’s direct operating costs and expenses, other than leased-in equipment expense, are grouped into the following categories: • • • personnel (primarily wages, benefits, payroll taxes, savings plans and travel for marine personnel); repairs and maintenance (primarily routine repairs and maintenance and main engine overhauls that are performed in accordance with planned maintenance programs); drydocking (primarily the cost of regulatory drydockings performed in accordance with applicable regulations); 45 • • • insurance and loss reserves (primarily the cost of Hull and Machinery and Protection and Indemnity insurance premiums and loss deductibles); fuel, lubes and supplies; and other (brokers’ commissions, communication costs, expenses incurred in mobilizing vessels between geographic regions, third party ship management fees, freight expenses, customs and importation duties and other). The Company expenses drydocking, engine overhaul and vessel mobilization costs as incurred. If a disproportionate number of drydockings, overhauls or mobilizations are undertaken in a particular fiscal year or quarter, operating expenses may vary significantly when compared with the prior year or prior quarter. 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 17. Major Customers and Segment Information” in the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Leased-in Equipment. In addition to the Company’s owned fleet, it currently operates one leased-in vessel from a lessor under a bareboat charter arrangement that expires in 2024. This vessel was previously owned and subject to a sale and leaseback transaction with the lessor. Impairments. When reviewing its fleet for impairment, the Company groups vessels with similar operating and marketing characteristics, including cold-stacked vessels expected to return to active service, into vessel classes. All other vessels, including vessels retired and removed from service, are evaluated for impairment on a vessel by vessel basis. During 2023, the Company recorded impairment charges of $0.7 million for one leased-in AHTS. During 2022, the Company recorded impairment charges of $1.6 million for one FSV that was sold during the year and one leased-in AHTS. During 2021, the Company recorded no impairment charges associated with its fleet. Estimated fair values for the Company’s owned vessels were established by independent appraisers and other market data such as recent sales of similar vessels. For information regarding the Company’s vessel fair value measurement determinations, see “Note 9. Fair Value Measurements” in the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. If market conditions continue to decline from the presently depressed utilization and rates per day worked experienced over the last three years, fair values based on future appraisals could decline significantly. The Company’s other vessel classes and other individual vessels in active service and cold-stacked status, for which no impairment was deemed necessary, have generally experienced a less severe decline in utilization and rates per day worked based on specific market factors. The market factors include vessels with more general utility to a broader range of customers (e.g., FSVs), vessels required for customers to meet regulatory mandates and operating under multiple year contracts or vessels that service customers outside of the offshore oil and natural gas market. For vessel classes and individual vessels with indicators of impairment, but which were not impaired as of December 31, 2023, the Company has estimated that their future undiscounted cash flows exceed their current carrying values. The Company’s estimates of future undiscounted cash flows are highly subjective as utilization and rates per day worked are uncertain, including the timing of an estimated market recovery in the offshore oil and natural gas markets and the timing and cost of reactivating cold-stacked vessels. If market conditions decline further, or remain stagnant at current levels, 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. 46 Consolidated Results of Operations For the years ended December 31, the Company’s consolidated results of operations were as follows (in thousands,

In addition, the Company recognized impairment charges of $0.7 million for one AHTS to adjust for indicative future cash flows and the cost to return the vessel to its owner. During 2022, gain on asset dispositions and impairments was $1.4 million, which included gains from the sale of one FSV, one liftboat previously removed from service, office space and other equipment for net cash proceeds of $6.7 million after transaction costs, and a gain of $3.1 million. In addition, the Company sold one AHTS in exchange for the remaining equity interests in SEACOR Marlin LLC (the owner of the PSV SEACOR Marlin) and recorded a gain on the sale of MexMar, OVH and other assets of $0.8 million (see “Note 4. Investments, at Equity and Advances to 50% or Less Owned Companies” in the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K). These gains were substantially offset by impairment charges of $2.9 million for one leased-in AHTS, as well as impairment charges for one FSV sold in 2022 and for other equipment classified as assets held for sale, which was subsequently sold in 2023. During 2021, the Company recorded no impairment charges associated with its fleet. The Company sold one PSV vessel, three FSVs and set off debt payments with hull and machinery insurance proceeds received in respect of the SEACOR Power of $25.0 million, for total payments of $30.1 million in cash, resulting in gains of $20.9 million all of which was recognized currently. The insurance proceeds from the SEACOR Power were primarily used to repay associated debt under the FGUSA Credit Facility as described in “Note 6. Long-Term Debt” in the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Other Income (Expense), Net For the years ended December 31, the Company’s other income (expense) was as follows (in thousands): Other Income (Expense): Interest income Interest expense SEACOR Holdings guarantee fees (Losses) gains on debt extinguishment Derivative gains, net Foreign currency (losses) gains, net Gain from return of investments in 50% or less owned companies and other, net 2023 2022 2021 $ $ $ 1,444 (37,504) — (2,004) 608 (2,133) $ 784 (29,706) — 10,429 — 1,659 — (39,589) $ 755 (16,079) $ 1,302 (28,111) (7) 61,994 391 (1,235) 9,441 43,775 Interest Income. Interest income increased in 2023 primarily due to interest received for the loan due from MexMar, which has now been fully repaid. Interest income decreased in 2022 primarily due to interest received from the U.S. Internal Revenue Service (“IRS”) due to delays in the payment of the CARES Act tax refunds in 2021. Interest income in 2021 increased primarily due to a tax refund on a portion of interest paid. 59 Interest expense. Interest expense was higher in 2023 compared to 2022 primarily due to a higher interest rate on the 2018 SMFH Credit Facility (which bore interest at a variable rate), a higher interest rate due to the refinancing of the 2018 SMFH Credit Facility with the 2023 SMFH Credit Facility (which bears interest at a fixed rate of 11.75%), a higher interest rate due to the exchange of the Old Convertible Notes (which bore interest at a fixed rate of 4.25%) for the Guaranteed Notes and the New Convertible Notes (which bear interest at a fixed rate of 8.0% and 4.25%, respectively), and higher interest rates on other variable rate debt as a result of the interest rate environment. Interest expense was higher in 2022 compared to 2021 primarily due to the debt assumed as a result of the OSV Partners Merger, a higher interest rate on the 2018 SMFH Credit Facility as a result of the entry into an Amendment No. 4 to 2018 SMFH Credit Facility, a higher interest rate due to the exchange of the Old Convertible Notes for the Guaranteed Notes and the New Convertible Notes and higher interest rates on all other variable rate debt as a result of the increasing interest rate environment. SEACOR Holdings guarantee fees. As of December 31, 2023 and 2022, there were no SEACOR Holdings outstanding guarantee fees as the obligations were terminated in 2021. (Losses) gains on debt extinguishment. Loss on debt extinguishment was $2.0 million in 2023 due to the exchange of the $130.0 million loan facility with a syndicate of lenders administered by DNB Bank ASA, dated September 26, 2018 (as amended from time to time, the “2018 SMFH Credit Facility”) for the 2023 SMFH Credit Facility. Gain on debt extinguishment was $10.4 million in 2022 due to the exchange of the Old Convertible Notes for the Guaranteed Notes and the New Convertible Notes. Gain on debt extinguishment was $62.0 million in 2021 due to the repayment of the FGUSA Credit Facility. For further information, see “Note 6. Long-Term Debt” in the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Derivative gains, net. Net derivative gains increased in 2023 compared to 2022 due to the Company entering into an open forward currency exchange contract in the fourth quarter of 2023. Net derivative gains in 2022 decreased compared to 2021 due to the Company not having any open forward currency exchange contracts since the first quarter of 2021. Foreign currency gains (losses), net. Foreign currency losses in 2023 compared to foreign currency gains in 2022 were primarily due to the strengthening of the pound sterling in relation to the U.S. dollar. Foreign currency gains in 2022 compared to foreign currency losses in 2021 were primarily due to the weakening of the pound sterling and euro in relation to the U.S. dollar. Gain from return of investments in 50% or less owned companies and other, net. Other gains in 2022 decreased compared to 2021 primarily due to a distribution in 2021 of $12.0 million from MEXMAR Offshore International LLC (“MEXMAR Offshore”), a previous joint venture 49% owned by a previously wholly owned subsidiary of the Company, and 51% owned by a subsidiary of Proyectos Globales de Energía y Servicios CME, S.A. de C.V. (“CME”), of which $9.4 million was in excess of the Company’s investment in the joint venture. The Company no longer has any equity interest in this joint venture. Income Tax Expense For the year ending December 31, 2023, the Company’s effective income tax rate of 216.2% was primarily due to foreign withholding taxes. For the year ending December 31, 2022, the Company’s effective income tax rate of 12.3% was primarily due to foreign taxes paid that are not creditable against U.S. income taxes, foreign losses for which there is no benefit in the U.S. and the sale of investments in 50% or less owned companies. For the year ending December 31, 2021, the Company’s effective income tax rate of 173.4% was primarily due to foreign taxes paid that are not creditable against U.S. income taxes and foreign subsidiaries with current losses for which there is no current or future federal income tax benefit available. Equity in Earnings (Losses) of 50% or Less Owned Companies, Net of Tax For the years ended December 31, the Company’s equity in earnings (losses) from continuing operations of 50% or less owned companies, net of tax, was as follows (in thousands): 2023 2022 2021 SEACOR Marine Arabia MexMar (1) MEXMAR Offshore (2) OVH (1) OSV Partners (3) Other $ $ $ 60 3,401 $ — $ — — — 155 3,556 $ 1,671 2,133 — 2,571 — 636 7,011 $ $ $ 1,030 10,491 2,563 809 (1,343) 1,528 15,078 (1) (2) (3) On September 29, 2022, the Company sold its ownership in this joint venture to the majority shareholder. See details below. On December 9, 2021, the Company sold their ownership in this joint venture to the majority shareholder. See details below. On December 31, 2021, the Company purchased the remaining shares in this joint venture that it did not own and consolidated the net assets of OSV Partners. See details below. 2023 compared with 2022 SEACOR Marine Arabia. The increase in equity earnings in 2023 from SEACOR Marine Arabia was due to increased day rates and utilization. 2022 compared with 2021 MexMar, OVH and SEACOR Marlin. On September 29, 2022, each of the transactions contemplated under that certain Framework Agreement, by and among SEACOR Marine and certain of its subsidiaries, on the one hand, and Operadora de Transportes Marítimos, S.A. de C.V. (“OTM”), CME Drillship Holdings DAC (“CME Ireland”), and Offshore Vessels Holding, S.A.P.I. de C.V. (“OVH”), on the other hand, were consummated (the “Framework Agreement Transactions”). As a result, the Company no longer owns any equity interest in either MexMar or in OVH, and the Company owns all of the equity interests in SEACOR Marlin LLC. OSV Partners. On December 31, 2021, SEACOR Marine, SEACOR Offshore OSV LLC, a wholly owned subsidiary of the Company (“SEACOR Offshore OSV”) and OSV Partners I entered into a certain merger agreement pursuant to which OSV Partners I merged with and into SEACOR Offshore OSV, with SEACOR Offshore OSV surviving the merger (the “OSV Partners Merger”). As a result of the OSV Partners Merger, the five 201 feet, 1,900 tons deadweight capacity, PSVs owned by OSV Partners I are now 100% owned by the Company and no longer included as equity in earnings. MEXMAR Offshore. As of December 31, 2021, the Company does not have any ownership interest in MEXMAR Offshore. 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 debt facilities. 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 ATM Program, which has approximately $24.9 million of authority remaining for sales. 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 December 31, 2023, the Company had unfunded capital commitments of $15.5 million for miscellaneous vessel equipment, including hybrid battery power systems. Of the unfunded capital commitments, $13.5 million is payable during 2024 and $2.0 million is payable during 2025. In addition to the unfunded capital commitments above, the Company has indefinitely deferred an additional $9.2 million of capital commitments with respect to one FSV. As of December 31, 2023, the Company had outstanding debt of $315.9 million, net of debt discount and issue costs. The Company’s contractual long-term debt maturities as of December 31, 2023 are as follows (in thousands): 2024 2025 2026 2027 2028 Years subsequent to 2028 Actual 28,365 28,605 152,405 27,165 110,257 6,227 353,024 $ $ As of December 31, 2023, the Company held balances of cash, cash equivalents and restricted cash totaling $84.1 million. As of December 31, 2022, the Company held balances of cash, cash equivalents and restricted cash totaling $43.0 million. 61 For the years ended December 31, the following is a summary of the Company’s cash flows (in thousands): Cash flows provided by or (used in): Operating Activities Investing Activities Financing Activities Effects of Exchange Rate Changes on Cash, Restricted Cash and Cash Equivalents Net Change in Cash, Restricted Cash and Cash Equivalents from Discontinued Operations Net Change in Cash, Restricted Cash and Cash Equivalents Operating Activities 2023 2022 2021 $ $ $ 8,947 49,126 (16,990) (14,616) $ 57,800 (41,355) 3 (4) — 41,086 $ — 1,825 $ 9,255 71,800 (79,180) (22) (171) 1,682 Cash flows provided by operating activities increased by $23.6 million in 2023 compared with 2022 primarily due to increases in day rates, which was partially offset by working capital timing. For the years ended December 31, the components of cash flows provided by (used in) continuing operating activities were as follows (in thousands): DVP: United States, primarily Gulf of Mexico Africa and Europe, Continuing Operations Middle East and Asia Latin America Operating, leased-in equipment Administrative and general (excluding provisions for bad debts and amortization of share awards) SEACOR Holdings management and guarantee fees Other, net (excluding non-cash losses) Dividends received from 50% or less owned companies Changes in operating assets and liabilities before interest and income taxes Cash settlements on derivative transactions, net Interest paid, excluding capitalized interest (1) Interest received Income taxes (paid) refunded, net Total cash flows provided by (used in) operating activities 2023 2022 2021 $ $ 17,082 38,678 31,805 32,296 (2,362) (39,664) — — 2,241 80,076 (38,743) 577 (31,446) 1,444 (2,961) 8,947 $ $ $ 10,161 15,518 3,226 16,435 (2,384) (35,825) — 755 3,057 10,943 (1,235) (749) (25,244) 784 885 (14,616) $ 1,847 9,819 10,043 21,826 (7,456) (31,329) (7) 168 5,332 10,243 (9,092) (2,150) (23,807) 1,302 32,759 9,255 (1) During 2023 and 2022, the Company had no capitalized interest. During 2021, capitalized interest included in purchases of property and equipment from continuing operations was $0.3 million. For a detailed discussion of the Company’s financial results for the reported periods, see “Consolidated Results of Operations” included above. Changes in operating assets and liabilities before interest and income taxes are the result of the Company’s working capital requirements. Investing Activities During 2023, net cash provided by investing activities was $49.1 million primarily as a result of the following: • • • capital expenditures were $10.6 million; the Company sold one liftboat, classified as held for sale, three liftboats and one specialty vessel, previously removed from service, one FSV and other equipment, previously classified as held for sale, as well as other equipment not previously classified as such, for net cash proceeds of $44.7 million, after transaction costs, and a gain of $21.1 million; the Company received $15.0 million of principal payments under that certain MexMar Third A&R Facility Agreement, dated September 29, 2022. The facility has now been paid in full. 62 During 2022, net cash provided by investing activities was $57.8 million primarily as a result of the following: • • • • • capital expenditures were $0.5 million; the Company sold one FSV, one liftboat previously removed from service, office space and other equipment for net cash proceeds of $6.7 million, after transaction costs, and a gain of $2.2 million; the Company received $0.5 million from investments in, and advances to, its 50% or less owned companies for principal payments on note receivables; the Company received $66.0 million of cash proceeds from the sale of investments in, and advances to, its 50% or less owned companies in the Framework Agreement Transactions; and the Company deployed $28.8 million to acquire the loans under the MexMar Third A&R Facility Agreement and received $13.8 million of principal payments under such loan. During 2021, net cash provided by investing activities was $71.8 million primarily as a result of the following: • • • • • • • capital expenditures were $7.0 million. Equipment deliveries during the period included one PSVs through construction; the Company sold three FSVs, one PSV and set off debt payments with hull and machinery insurance proceeds from the SEACOR Power of $25.0 million, for a total of $30.1 million; the Company completed the sale of Windcat Workboats for net proceeds of $38.7 million ($42.2 million cash, less $3.5 million cash held at Windcat Workboats that was included in the assets purchased by the buyer); the Company made investments in, and advances to, its 50% or less owned companies of $3.0 million; the Company received a distribution from its MEXMAR Offshore joint venture in the amount of $12.0 million of which $9.4 million was in excess of the Company’s investment balance of $2.6 million; the Company received $3.3 million from investments in, and advances to, its 50% or less owned companies for principal payments on note receivables; and the Company received $0.2 million as part of an asset acquisition of a 50% or less owned company. Financing Activities During 2023, net cash used by financing activities was $17.0 million primarily as a result of the following: • • • • • • • The Company made scheduled payments on long-term debt and other obligations of $29.2 million; the Company made payments for debt extinguishment of $131.6 million; the Company made payments for debt extinguishment costs of $1.8 million; the Company received proceeds from the issuance of long-term debt of $148.5 million; the Company made payments on finance leases of $0.5 million; the Company made payments on tax withholdings for restricted stock vesting and director share awards of $2.4 million; and the Company received net proceeds of less than $0.1 million from the issuance and sale of Common Stock through the ATM Program. During 2022, net cash used by financing activities was $41.4 million primarily as a result of the following: • • • The Company made scheduled payments on long-term debt and other obligations of $38.2 million; the Company made payments for debt extinguishment costs of $2.3 million; the Company received $0.2 million proceeds from the exercise of stock options; 63 • • the Company made payments on finance leases of $0.4 million; and the Company made payments on tax withholdings for restricted stock vesting and director share awards of $0.7 million. During 2021, net cash used by financing activities was $78.9 million primarily as a result of the following: • • • The Company made scheduled payments on long-term debt and other obligations of $78.1 million; and the Company made payments on debt extinguishment costs of $0.8 million; and the Company made payments on tax withholdings for restricted stock vesting and director share awards of $0.3 million. Short and Long-Term Liquidity Requirements and Outlook 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 $24.9 million in remaining capacity under the ATM Program, will provide sufficient liquidity to meet its obligations, including to support its capital expenditures program, working capital needs, debt service requirements and covenant compliance over the short to long term. 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 credit facilities. Future Cash Requirements The Company’s primary future cash requirements will be to fund operations, debt service, capital expenditures, employee retirement benefit plans, and lease payment obligations. In addition, the Company may use cash in the future to make strategic acquisitions or investments. Specifically, the Company expects its primary cash requirements for fiscal year 2024 to be as follows: • Debt service — We expect to make principal and interest payments of approximately $59.9 million during fiscal year 2024 under our currently outstanding debt facilities based on interest rates at year end. • • • Capital expenditures — At this time, we expect capital expenditures of approximately $15.5 million for the installation of hybrid battery power systems and other capital expenditures. Employee retirement benefit plans — We estimate we will make payments under our retirement benefit plans of approximately $1.6 million during fiscal year 2024. Lease payments — We expect to make lease payments of approximately $1.9 million for our operating and finance leases during fiscal year 2024 under our effective leases as of December 31, 2023. In addition to the matters identified above, in the ordinary course of business, the Company may be involved in litigation, claims, government inquiries, investigations and proceedings relating to commercial, employment, environmental and regulatory matters. An unfavorable resolution in this or other matters could have a material adverse effect on the Company's future cash requirements. Debt Securities and Credit Agreements For a discussion of the Company’s debt securities and credit agreements, see “Note 6. Long-Term Debt” in the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Contingencies MNOPF and MNRPF. Certain of the Company’s subsidiaries are participating employers in two industry-wide, multi- employer, defined benefit pension funds in the U.K.: the MNOPF and the 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 December 31, 2023, all invoices received related to MNOPF and MNRPF have been settled in full. 64 On October 19, 2021, the Company was informed by the MNRPF that two issues had been identified during a review of the MNRPF by the applicable trustee that would potentially give rise to material additional liabilities for the MNRPF. On November 23, 2023, the trustee advised that following the tri-annual valuation, $1.5 million (£1.2 million) of the potential cumulative funding deficit of the MNRPF was allocated to the Company as a participating employer, including the additional liabilities mentioned above. During 2023, the Company recognized payroll related operating expenses of $1.5 million (£1.2 million) for its allocated share of the potential cumulative funding deficit, which the Company will be invoiced for during 2024 and 2025. Other. 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 such changes in estimated costs would have a material effect on the Company’s consolidated financial position, results of operations or cash flows. Related Party Transactions For a discussion of the Company’s transactions with related parties, see “Note 15. Related Party Transactions” in the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Critical Accounting Policies and 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. Actual results could differ from estimates and those differences may be material. For a summary of the Company’s accounting policies, see “Note 1. “Nature of Operations and Accounting Policies” in the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K, which should be read in conjunction with this MD&A. Management considers an accounting estimate to be critical if it is important to the Company’s financial condition or results of operations and requires the Company to make subjective or complex judgments or estimates about matters that are uncertain. The Company believes the following critical accounting policies are the ones that require significant judgments and estimates to prepare its consolidated financial statements. There are other items within our consolidated financial statements that require estimation and judgment, but they are not deemed critical as defined above. 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. 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 December 31, 2023, 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. 65 Business Combinations. For acquisitions constituting a business acquisition, the Company recognizes 100% of the fair value of assets acquired, liabilities assumed, and noncontrolling interests when the acquisition constitutes a change in control of the acquired entity. Shares issued in consideration for a business combination, contingent consideration arrangements and pre-acquisition loss and gain contingencies are all measured and recorded at their acquisition-date fair value. Subsequent changes to fair value of contingent consideration arrangements are generally reflected in earnings. Acquisition-related transaction costs are expensed as incurred and any changes in an acquirer’s existing income tax valuation allowances and tax uncertainty accruals are recorded as an adjustment to income tax expense. The operating results of entities acquired are included in the accompanying consolidated statements of income (loss) from the date of acquisition. If an acquisition of an asset or group of assets does not meet the definition of a business, the transaction is accounted for as an asset acquisition. The assets are measured based on their cost to the Company, including transaction costs. The acquisition cost is then allocated to the assets acquired based on their relative fair values. Income Taxes. Deferred income tax assets and liabilities have been provided in recognition of the income tax effect attributable to the book and tax basis differences of assets and liabilities reported in the accompanying consolidated financial statements. Deferred tax assets or liabilities are provided using the enacted tax rates expected to apply to taxable income in the periods in which they are expected to be settled or realized. Interest and penalties relating to uncertain tax positions are recognized in interest expense and administrative and general, respectively, in the accompanying consolidated statements of income (loss). The Company records a valuation allowance to reduce its deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Global Intangible Low Taxed Income (“GILTI”) regime effectively imposes a minimum tax on worldwide foreign earnings and subjects U.S. shareholders of controlled foreign corporations (“CFCs”) to current taxation on certain income earned through a CFC. The Company has made the policy election to record any liability associated with GILTI in the period in which it is incurred. In the normal course of business, the Company may be subject to challenges from tax authorities regarding the amount of taxes due for the Company. These challenges may alter the timing or amount of taxable income or deductions. As part of the calculation of income tax expense, the Company determines whether the benefits of its tax positions are at least more likely than not of being sustained based on the technical merits of the tax position. For tax positions that are more likely than not of being sustained, the Company accrues the largest amount of the tax benefit that is more likely than not of being sustained. Such accruals require management to make estimates and judgments with respect to the ultimate outcome of its tax benefits and actual results could vary materially from these estimates. 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. 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. 66 ITEM 7A. Quantitative and Qualitative Disclosures about Market Risk With respect to the Company’s international business, the Company is exposed to foreign currency exchange rate fluctuations and exchange rate risks on charter hire contracts and operational expenses denominated in foreign currencies. To minimize the financial impact of these items, the Company attempts to contract its services in U.S. dollars. In addition, the Company attempts to minimize the financial impact of these risks by matching the currency of the Company’s operating expenses with the currency of the revenue streams when considered appropriate. The Company generally does not hedge against any foreign currency rate fluctuations associated with foreign currency contracts that arise in the normal course of business, which exposes the Company to the risk of exchange rate losses. On occasion, the Company does, however, enter into forward currency exchange, option and future contracts with respect to various foreign currencies that are not designated as fair value hedges in connection with non-ordinary course transactions. These contracts enable the Company to buy currencies in the future at fixed exchange rates, which could offset possible consequences of changes in foreign exchange rates with respect to the Company’s international business. As of December 31, 2020, the Company had a foreign currency forward contract from which we recorded a loss of $0.9 million related to a £31.5 million swap that settled on January 12, 2021. The Company’s outstanding debt from continuing operations is primarily in fixed interest rate instruments or variable interest rate instruments. As of December 31, 2023, the Company had outstanding variable rate debt instruments (due 2028 through 2029) subject to interest rate fluctuations totaling $68.6 million that call for the Company to pay interest based on the London Interbank Offered Rate (“LIBOR”) plus applicable margins. The interest rates reset quarterly. As of December 31, 2023, the average interest rate on these variable rate borrowings was 9.7%. For each 1% increase in each of the applicable LIBOR rate, the Company’s annual interest payments on variable rate borrowings would increase by approximately $0.7 million. As a result, the Company’s operations are not significantly affected by interest rate fluctuations. ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA The consolidated financial statements and related notes are included in Part IV of this Annual Report on Form 10-K and incorporated herein by reference. ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES 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 December 31, 2023. 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 December 31, 2023 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 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. The Company’s disclosure controls and procedures have been designed to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, to allow timely decisions regarding required disclosures. All internal control systems, no matter how well designed, have inherent limitations. 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. 67 Management’s Annual Report on Internal Control Over Financial Reporting Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act). The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles in the U.S. and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and Directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements. Internal control over financial reporting is designed to provide reasonable assurance to the Company’s management and Board of Directors regarding the preparation of reliable financial statements for external purposes in accordance with generally accepted accounting principles in the U.S. Because of the inherent limitations in any internal control system, no matter how well designed, misstatements may occur and not be prevented or detected. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Management conducted an evaluation of the effectiveness of the Company’s system of internal control over financial reporting as of December 31, 2023 based on the updated framework set forth in “Internal Control-Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on its evaluation, management concluded that, as of December 31, 2023, the Company’s internal control over financial reporting was effective. Grant Thornton LLP has issued a report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2023, which is included in Part II, Item 8 of this Annual Report on Form 10-K. 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 quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated February 29, 2024 expressed an unqualified opinion. Basis for opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical audit matters Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters. GRANT THORNTON LLP (signed manually) We have served as the Company’s auditor since 2017.

Opinion on internal control over financial reporting We have audited the internal control over financial reporting of SEACOR Marine Holdings Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2023, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated financial statements of the Company as of and for the year ended December 31, 2023, and our report dated February 29, 2024 expressed an unqualified opinion on those financial statements. Basis for opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and limitations of internal control over financial reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. NATURE OF OPERATIONS AND ACCOUNTING POLICIES Nature of Operations and Segmentation. The consolidated financial statements include the accounts of SEACOR Marine Holdings Inc. (“SEACOR Marine”), and its consolidated subsidiaries (collectively referred to as the “Company”). The Company provides global marine and support transportation services to offshore energy facilities worldwide. 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, (iv) carry and launch equipment used underwater in drilling and well installation, maintenance, inspection and repair and (v) handle anchors and mooring equipment for offshore rigs and platforms. Additionally, the Company's vessels provide emergency response services and accommodations for technicians and specialists. Accounting standards require public business enterprises to report information about each of their operating business segments that exceed certain quantitative thresholds or meet certain other reporting requirements. Operating business segments have been defined as a component of an enterprise about which separate financial information is available and is evaluated regularly by the chief operating decision maker in assessing performance. Upon the Company’s sale of Windcat Workboats Holdings Limited (“Windcat Workboats”) on January 12, 2021, the Company’s European operations were no longer analyzed by the chief operating decision maker on a standalone basis but rather as part of the Africa and Europe segment. As a result, for purposes of segment reporting, European operations are now combined with the Africa segment and reported as a combined segment and prior period information has been conformed to the new consolidated reporting segment. The Company has identified the following four principal geographic regions as its reporting segments: United States, primarily Gulf of Mexico. As of December 31, 2023, 13 vessels were located in this region, including 11 owned and two managed. The Company’s vessels in this market support oil and natural gas exploration and production activities, seasonal construction, decommissioning and diving support operations, as well as the construction and maintenance of offshore wind farms in the Northeast of the U.S. Africa and Europe, continuing operations. As of December 31, 2023, 19 vessels were located in this region, including 18 owned and one leased-in. The Company’s vessels in this market generally support projects for major oil companies, primarily in Angola, Nigeria and the North Sea. Middle East and Asia. As of December 31, 2023, 16 vessels were located in this region, including 15 owned and one managed. The Company’s vessels in this area generally support exploration, personnel transport and seasonal construction activities in Saudi Arabia, United Arab Emirates, Qatar, Egypt and Israel. Latin America. As of December 31, 2023, ten owned vessels were located in this region. The Company’s vessels in this area generally provide support for exploration and production activities primarily in Mexico, Guyana and Trinidad and Tobago. From time to time, the Company’s vessels also work in Brazil and Colombia. 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. 83 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. 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. 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 unearned revenue in the accompanying consolidated balance sheets, for the years ended December 31 were as follows (in thousands): Balance at beginning of year Unearned revenues during the year Revenues recognized during the year Balance at end of year 2023 2022 2021 2,333 6,501 (8,147) 687 $ $ 1,606 4,288 (3,561) 2,333 $ $ 4,452 10,167 (13,013) 1,606 $ $ As of December 31, 2023, December 31, 2022 and December 31, 2021, the Company had unearned revenue of $0.7 million, $2.3 million and $1.6 million, respectively, primarily related to mobilization of vessels. 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. 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. During the year ended December 31, 2023, the Company recognized an aggregate amount of business interruption insurance recoveries of $6.5 million included in operating revenues in the accompanying consolidated statements of income (loss). Direct Operating Expenses. Direct operating costs and expenses, other than leased-in expense, consist primarily of costs such as personnel; repairs and maintenance; drydocking; insurance and loss reserves; fuel, lubes and supplies; and other vessel expenses, which include 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. 84 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. Cash equivalents consist of U.S. treasury securities, money market instruments, time deposits and overnight investments. A portion of the Company’s cash is maintained at federally insured financial institutions. The deposits held at these institutions are in excess of federally insured limits. The Company has not experienced any losses in such accounts and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institution in which those deposits are held. Restricted Cash. Restricted cash primarily relates to banking facility requirements. For the years ended December 31, cash, cash equivalents and restricted cash consists of: Cash Restricted cash Total 2023 2022 67,455 16,676 84,131 $ $ 39,963 3,082 43,045 $ $ 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, but excludes our short-term note receivable. 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. Trade receivables that are deemed uncollectible and are removed from accounts receivable and the allowance for credit losses when collection efforts have been exhausted. Derivative Instruments. The Company accounts for derivatives through the use of a fair value concept whereby all of the Company’s derivative positions are stated at fair value in the accompanying consolidated balance sheets. Realized and unrealized gains and losses on derivatives not designated as hedges are reported in the accompanying consolidated statements of income (loss) as Derivative gains (losses), net. Realized and unrealized gains and losses on derivatives designated as fair value hedges are recognized as corresponding increases or decreases in the fair value of the underlying hedged item to the extent they are effective, with any ineffective portion reported in the accompanying consolidated statements of income (loss) as Derivative gains (losses), net, and related cash flows are classified in the same category on the cash flow statement as the cash flows from the items being hedged. Realized and unrealized gains and losses on derivatives designated as cash flow hedges are reported as a component of other comprehensive income (loss) in the accompanying consolidated statements of comprehensive income (loss) to the extent they are effective and reclassified into earnings on the same line item associated with the hedged transaction and in the same period the hedged transaction affects earnings and related cash flows are classified in the same category on the cash flow statement as the cash flows from the items being hedged. Any ineffective portions of cash flow hedges are reported in the accompanying consolidated statements of income (loss) as Derivative gains (losses), net. Realized and unrealized gains and losses on derivatives designated as cash flow hedges that are entered into by the Company’s 50% or less owned companies are also reported as a component of the Company’s other comprehensive income (loss) in proportion to the Company’s ownership percentage, with reclassifications and ineffective portions being included in Equity in earnings of 50% or less owned companies, net of tax, in the accompanying consolidated statements of income (loss). Concentrations of Credit Risk. The Company is exposed to concentrations of credit risk associated with its cash and cash equivalents, restricted cash and derivative instruments. The Company minimizes its credit risk relating to these positions by monitoring the financial condition of the financial institutions and counterparties involved and by primarily conducting business with large, well- established financial institutions and diversifying its counterparties. The Company does not currently anticipate nonperformance by any of its significant counterparties. The Company is also exposed to concentrations of credit risk relating to its receivables due from customers described above. The Company does not generally require collateral or other security to support its outstanding receivables. The Company minimizes its credit risk relating to receivables by performing ongoing credit evaluations and, to date, credit losses have not been material. Inventories. Inventories, which consist of fuel and supplies, are stated at the lower of cost (using the first-in, first-out method) or net realizable value. The Company records write-downs, as needed, to adjust the carrying amount of inventories to the lower of cost or net realizable value. In the years ended December 31, 2023, 2022 and 2021, there were no inventory reserves. 85 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 December 31, 2023, the estimated useful life of the Company’s new offshore support vessels was 20 years. The Company’s property and equipment as of December 31 was as follows (in thousands): 2023 2022 Offshore support vessels: AHTS(2) FSV(3) PSV (4) Liftboats General machinery and spares Other (5) Offshore support vessels: AHTS(2) FSV(3) PSV (4) Specialty Liftboats General machinery and spares Other (5) Historical Cost (1) Accumulated Depreciation Net Book Value $ $ $ $ 12,112 340,411 301,461 243,295 9,343 12,201 918,823 27,281 354,473 295,875 3,163 264,142 10,148 12,601 967,683 $ $ $ $ (4,578) $ (142,096) (53,100) (103,459) (9,161) (11,747) (324,141) $ (18,139) $ (130,599) (36,112) (3,138) (102,156) (8,565) (12,069) (310,778) $ 7,534 198,315 248,361 139,836 182 454 594,682 9,142 223,874 259,763 25 161,986 1,583 532 656,905 (1) (2) (3) (4) (5) Includes property and equipment acquired in business acquisitions at acquisition date fair value and net of the impact of recognized impairment charges. Some of the Company’s vessels are pledged as security for certain loans. Anchor Handling Towing Supply vessels (“AHTS”). Fast support vessels (“FSVs”). Platform support vessels (“PSVs”). Includes buildings, leasehold improvements, vehicles and other property and equipment. Depreciation and amortization expense totaled $53.8 million, $56.0 million and $57.4 million in 2023, 2022 and 2021, respectively. There was no depreciation and amortization expense from discontinued operations in 2023, 2022 or 2021. 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 in 2023 or 2022. Capitalized interest totaled $0.3 million in 2021. Assets Held for Sale. As of December 31, 2023, one AHTS previously included in the Africa and Europe segment, with a carrying value of $0.5 million, was classified as assets held for sale as the Company expects to sell the vessel 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 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. 86 As a result of the difficult conditions experienced in the offshore oil and natural gas markets beginning in the second half of 2014 and the corresponding reductions in utilization and rates per day worked of its fleet, the Company identified indicators of impairment and recognized impairment charges primarily associated with its AHTS fleet, its liftboat fleet, certain specialty vessels and vessels removed from service. When reviewing its fleet for impairment, the Company groups vessels with similar operating and marketing characteristics, including cold-stacked vessels expected to return to active service, into vessel classes. All other vessels, including vessels retired and removed from service, are evaluated for impairment on a vessel by vessel basis. During the year ended December 31, 2023, the Company recorded impairment charges totaling $0.7 million for one leased-in AHTS to adjust for indicative future cash flows and the cost to return the vessel to its owner. During the year ended December 31, 2022, the Company recorded impairment charges totaling $2.9 million. The Company recorded impairment charges of $0.9 million for one FSV classified as held for sale and sold during 2022. In addition, the Company recorded impairment charges of $0.7 million for one leased-in AHTS as it is not expected to return to active service during its remaining lease term. Additionally, the Company recorded impairment charges of $1.3 million for other equipment and classified such equipment as assets held for sale as the Company expects to sell the equipment within one year. The impairment charges for the assets held for sale are included in (losses) gains on asset dispositions and impairments in the accompanying consolidated statements of income (loss). There were no impairments of other owned or leased-in vessels. The Company’s other vessel classes and other individual vessels in active service and cold-stacked status, for which no impairment was deemed necessary, have generally experienced a less severe decline in utilization and rates per day worked based on specific market factors. The market factors include vessels with more general utility to a broad range of customers (e.g., FSVs), vessels required for customers to meet regulatory mandates and operating under multiple year contracts or vessels that service customers outside of the offshore oil and natural gas market. For vessel classes and individual vessels with indicators of impairment as of December 31, 2023, 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. No impairment charges of investments in 50% or less owned companies were incurred for the years ended December 31, 2023, 2022 and 2021. Business Combinations. For acquisitions constituting a business acquisition, the Company recognizes 100% of the fair value of assets acquired, liabilities assumed, and noncontrolling interests when the acquisition constitutes a change in control of the acquired entity. Shares issued in consideration for a business combination, contingent consideration arrangements and pre-acquisition loss and gain contingencies are all measured and recorded at their acquisition-date fair value. Subsequent changes to fair value of contingent consideration arrangements are generally reflected in earnings. Acquisition-related transaction costs are expensed as incurred and any changes in an acquirer’s existing income tax valuation allowances and tax uncertainty accruals are recorded as an adjustment to income tax expense. The operating results of entities acquired are included in the accompanying consolidated statements of income (loss) from the date of acquisition. If an acquisition of an asset or group of assets does not meet the definition of a business, the transaction is accounted for as an asset acquisition. The assets are measured based on their cost to the Company, including transaction costs. The acquisition cost is then allocated to the assets acquired based on their relative fair values. Debt Discount and Issue Costs. Debt discounts and costs incurred in connection with the issuance of debt are amortized over the life of the related debt using the effective interest rate method for term loans and straight-line method for revolving credit facilities and are included in interest expense in the accompanying consolidated statements of income (loss). 87 Self-insurance Liabilities. The Company maintains marine hull, liability and war risk, general liability, workers compensation and other insurance customary in the industry in which it operates. Both the marine hull and liability policies have annual aggregate deductibles. Marine hull annual aggregate deductibles are accrued as claims are incurred while marine liability annual aggregate deductibles are accrued based on historical loss experience. Exposure to the health benefit plans are limited by maintaining stop-loss and aggregate liability coverage. To the extent that estimated self-insurance losses, including the accrual of annual aggregate deductibles, differ from actual losses realized, the Company’s insurance reserves could differ significantly and may result in either higher or lower insurance expense in future periods. Income Taxes. Deferred income tax assets and liabilities have been provided in recognition of the income tax effect attributable to the book and tax basis differences of assets and liabilities reported in the consolidated financial statements. Deferred tax assets or liabilities are provided using the enacted tax rates expected to apply to taxable income in the periods in which they are expected to be settled or realized. Interest and penalties relating to uncertain tax positions are recognized in interest expense and administrative and general, respectively, in the accompanying consolidated statements of income (loss). The Company records a valuation allowance to reduce its deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Global Intangible Low Taxed Income (“GILTI”) regime effectively imposes a minimum tax on worldwide foreign earnings and subjects U.S. shareholders of controlled foreign corporations (“CFCs”) to current taxation on certain income earned through a CFC. The Company has made the policy election to record any liability associated with GILTI in the period in which it is incurred. In the normal course of business, the Company may be subject to challenges from tax authorities regarding the amount of taxes due for the Company. These challenges may alter the timing or amount of taxable income or deductions. As part of the calculation of income tax expense, the Company determines whether the benefits of its tax positions are at least more likely than not of being sustained based on the technical merits of the tax position. For tax positions that are more likely than not of being sustained, the Company accrues the largest amount of the tax benefit that is more likely than not of being sustained. Such accruals require management to make estimates and judgments with respect to the ultimate outcome of its tax benefits and actual results could vary materially from these estimates. Foreign Currency Translation. The assets, liabilities and results of operations of certain consolidated subsidiaries are measured using their functional currency, which is the currency of the primary foreign economic environment in which they operate. Upon consolidating these subsidiaries with the Company, their assets and liabilities are translated to U.S. dollars at currency exchange rates as of the consolidated balance sheet dates and their revenues and expenses are translated at the weighted average currency exchange rates during the applicable reporting periods. Translation adjustments resulting from the process of translating these subsidiaries’ financial statements are reported in other comprehensive income in the accompanying consolidated statements of comprehensive income (loss). Foreign Currency Transactions. Certain consolidated subsidiaries enter into transactions denominated in currencies other than their functional currency. Gains and losses resulting from changes in currency exchange rates between the functional currency and the currency in which a transaction is denominated are included in foreign currency losses, net in the accompanying consolidated statements of income (loss) in the period in which the currency exchange rates change. Accumulated Other Comprehensive (Loss) Income. The components of accumulated other comprehensive (loss) income were as follows (in thousands): SEACOR Marine Holdings Inc. Stockholders’ Equity Noncontrolling Interests Year Ended December 31, 2020 Other comprehensive income Income tax (expense) Year Ended December 31, 2021 Other comprehensive loss Income tax benefit (expense) Year Ended December 31, 2022 Other comprehensive income Income tax benefit (expense) Year Ended December 31, 2023 Foreign Currency Translation Adjustments 6,797 $ 3,986 — 10,783 (4,451) — 6,332 1,245 — 7,577 $ Derivative (Losses) Gains on Cash Flow Hedges, net $ Foreign Currency Translation Adjustments $ Derivative Losses on Cash Flow Hedges, net Other Comprehensive Income (Loss) 1,242 5,265 — 5,265 (1,208) — (1,208) 730 — 730 (11) $ — — (11) $ — $ — (11) $ — — (11) $ (1,445) $ — — (1,445) — — (1,445) — — (1,445) $ (4,007) $ 1,279 — (2,728) 3,243 — 515 (515) — — $ Total 2,790 5,265 — 8,055 (1,208) — 6,847 730 — 7,577 88 $ $ Earnings (Loss) Per Share. Basic earnings/loss per share of the common stock, par value $0.01 per share, of SEACOR Marine (“Common Stock”) 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 Old Convertible Notes and the New Convertible Notes (as defined in “Note 6. Long-Term Debt”) unless anti-dilutive. For the years ended December 31, 2023 and 2022, diluted loss per common share of the Company excluded 2,978,274 shares issuable upon the conversion of the New Convertible Notes as the effect of their inclusion in the computation would be anti-dilutive. For the year ended December 31, 2021, diluted earnings per common share of the Company excluded 2,907,500 shares issuable upon the conversion of the Old Convertible Notes as the effect of their inclusion in the computation would be anti-dilutive. In addition, for the years ended December 31, 2023, 2022 and 2021, diluted (loss) earnings per common share of the Company excluded 1,642,084 shares, 1,682,193 shares and 1,112,256 shares, respectively, of restricted stock and 1,026,031, 1,026,865 and 1,061,357 of outstanding stock options as the effect of their inclusion in the computation would be anti-dilutive. For the year ended December 31, 2021, diluted earnings per share of Common Stock of the Company included 50,834 shares of restricted stock as the effect of their inclusion in the computation is dilutive, with no related income effect. In 2023, 2022 and 2021, the Company issued 156,620, 184,930 and 157,455 performance share awards, of which 156,620 were not considered outstanding as of December 31, 2023. These performance share awards are not considered outstanding until such time as they would be probable of being exercised, therefore they were not included in the computation of earnings (loss) per share. Recently Adopted Accounting Standards Recently Issued Accounting Standards. On December 14, 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities to disclose 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 has not yet determined the impact that the adoption of the standard will have on the Company’s consolidated financial position, results of operations and disclosures. On November 27, 2023, the 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. While early adoption is permitted, the Company has determined it will not early adopt the standard. The Company has not yet determined the impact that the adoption of the standard will have on the Company’s consolidated financial position, results of operations and disclosures. On October 9, 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s 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 disclosures included herein. 2. NOTE RECEIVABLE In connection with the closing of the Framework Agreement Transactions (as defined in “Note 4. Investments, at Equity and Advances to 50% or Less Owned Companies”), on September 29, 2022, SEACOR Marine Capital Inc., a wholly owned subsidiary of the Company (“SEACOR Marine Capital”) purchased all of the outstanding loans under the Second Amended and Restated Term Loan Credit Facility Agreement, made as of July 8, 2022, by and among Mantenimiento Express Marítimo, S.A.P.I. de C.V.

Excludes four liftboats that were previously removed from service, of which three were sold in 2023 and one was sold in 2022. On January 12, 2021, a wholly owned subsidiary of the Company, completed the sale of the Company’s Windcat Workboats crew transfer vessel (“CTV”) business through the sale of 100% of the equity of Windcat Workboats, a wholly owned subsidiary of the Company (“Windcat” and together with its subsidiaries, the “Windcat Group”), to CMB N.V. (the “Windcat Buyer”) pursuant to a Sale and Purchase Agreement entered into on December 18, 2020. At closing, the Windcat Buyer paid to the Company an aggregate purchase price of £32.8 million. After deducting transaction costs and expenses and giving effect to foreign exchange rate hedges, the Company received net cash proceeds of approximately $42.6 million. The Windcat Buyer also assumed all of the approximately £20.4 million of debt outstanding under Windcat Workboat’s existing revolving credit facility. As of December 31, 2020, the Windcat Group owned a total of 41 CTVs and held interests in an additional five CTVs through its joint ventures, all of which were included in the sale.

OTM and CME Ireland are affiliates of Proyectos Globales de Energía y Servicios CME, S.A. de C.V. (“CME”). Alfredo Miguel Bejos is the President and Chief Executive Officer of CME and also serves as a member of SEACOR Marine’s board of directors (“Board of Directors”).

The Company also owned a minority interest in SEACOR Marlin LLC (“SEACOR Marlin LLC”), the owner of the PSV SEACOR Marlin, and the remaining ownership interests of SEACOR Marlin LLC were held by MexMar. The Framework Agreement provided for, among other things, (i) the sale by SEACOR Marine LLC, a wholly owned subsidiary of the Company (“SMLLC”), of all of the outstanding equity interests of SEACOR Marine International to OTM for a purchase price of $66.0 million in cash, (ii) the sale of the AHTS SEACOR Davis to CME Ireland in exchange for the remaining equity interests in SEACOR Marlin LLC, such that SEACOR Marlin LLC became a wholly owned subsidiary of the Company, (iii) the transfer of a hybrid battery power system from OVH to SEACOR Marine Capital as repayment in full of a certain vessel loan agreement provided by the Company to its former joint venture, and (iv) entry into a bareboat charter agreement between SEACOR Marlin LLC and MexMar (collectively, the “Framework Agreement Transactions”).

As a result of the Framework Agreement Transactions, the Company no longer owns any equity interest in either MexMar or in OVH, and the Company owns all of the equity interests in SEACOR Marlin LLC, which owns the PSV SEACOR Marlin. Accordingly, the Company does not currently operate any joint-ventured vessels, which prior to the transactions were comprised solely of the 19 offshore support vessels owned by MexMar and OVH and the one PSV owned by SEACOR Marlin LLC. The vessel owned by SEACOR Marlin LLC became wholly owned in the transaction. The Company recognized a gain on the sale of MexMar, OVH and other assets of approximately $0.8 million, calculated as follows: 91 Total Cash Received 51% ownership in SEACOR Marlin Joint Venture Hybrid Battery Power System Less: Transaction Fees and other Costs Total Net Proceeds Less: Net Equity in MexMar and OVH Joint Ventures Less: Net Book Value of SEACOR Davis Less: OVH Note Receivable Gain on Sale of MexMar, OVH and Other Assets September 29, 2022 66,000 7,000 1,394 1,159 73,235 65,546 5,507 1,394 788 $ $ MexMar Management Fees.

As a result of the Framework Agreement Transactions, the Company owns all of the equity interests in SEACOR Marlin LLC. The results of operations of SEACOR Marlin LLC are included in net income (loss) in the “Combined Condensed Financial Information of Other Investees” for the year ended December 31, 2021 and for the portion of 2022 that the entity was a 50% or less owned company.

(“CME”), UP Offshore (Bahamas) Ltd. (“UP Offshore”), a provider of offshore support vessel services to the energy industry in Brazil and a wholly owned subsidiary of MEXMAR Offshore, and certain subsidiaries of UP Offshore, completed the sale of eight vessels and certain Brazilian entities to OceanPact Servícos Marítimos S.A. and its subsidiary, OceanPact Netherlands B.V., for a total purchase price of $30.2 million (the “UP Offshore Sale Transaction”). The UP Offshore Sale Transaction resulted in an equity earnings gain from 50% or less owned companies of $2.6 million. MEXMAR Offshore – Distribution and Winddown. On July 23, 2021, the Company received a distribution from MEXMAR Offshore in connection with the UP Offshore Sale Transaction in the amount of $12.0 million of which $9.4 million was in excess of the Company’s investment balance of $2.6 million. The excess was recorded by the Company in the third quarter as a gain from return of investments in 50% or less owned companies. After giving effect to the UP Offshore Sale Transaction, MEXMAR Offshore, indirectly through certain subsidiaries of UP Offshore, retained ownership of three vessels. As part of the winddown of the MEXMAR Offshore joint venture, ownership of two of these vessels was transferred from subsidiaries of UP Offshore to OVH on October 26, 2021, and the remaining vessel was transferred from a subsidiary of UP Offshore to OVH on November 2, 2021. Upon completion of these transactions, MEXMAR Offshore no longer held income producing assets and as a result, on December 9, 2021, the Company transferred its 49% interest in MEXMAR Offshore to a subsidiary of CME for nominal consideration and a transaction fee of $0.2 million. As of December 31, 2021, the Company does not have any ownership interest in MEXMAR Offshore. The results of operations of MexMar Offshore are included in net income (loss) in the “Combined Condensed Financial Information of Other Investees” for the year ended December 31, 2021 for the period the entity was a 50% or less owned company.

LEASES The Company assesses at contract inception whether a contract is, or contains, a lease, defined as a contract that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. In calculating the present value of lease payments, the Company uses its incremental borrowing rate at the lease commencement date when the interest rate implicit in the lease is not readily determinable and includes the Company’s assessment and impact of any extensions, escalations or special terms. The Company applies the short-term lease recognition exemption to its short-term leases of machinery and equipment (i.e., those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered to be low value. As of December 31, 2023, the Company leased-in one AHTS and certain facilities and other equipment. The leases typically contain purchase and renewal options or rights of first refusal with respect to the sale or lease of the equipment. As of December 31, 2023, the lease terms of the vessel had a remaining duration of nine months. The lease terms of certain facilities and other equipment range in duration from two to 276 months.

The Company’s contractual long-term debt maturities from continuing operations for the years ended December 31 were as follows (in thousands): 2024 2025 2026 2027 2028 Years subsequent to 2028 $ $ 28,365 28,605 152,405 27,165 110,257 6,227 353,024 94 As of December 31, 2023, the Company was in compliance with all debt covenants and lender requirements. The Carlyle Investment. On December 1, 2015, the Company issued $175.0 million in aggregate principal amount of its convertible senior notes due 2023 (the “Old Convertible Notes”), at an annual interest rate of 3.75%, initially due December 1, 2022, (subsequently amended to December 2, 2023 as described below) to certain funds affiliated with The Carlyle Group Inc. (“Carlyle” and such funds, the “Carlyle Investors”). The Old Convertible Notes were convertible into shares of Common Stock at a conversion rate of 23.26 shares per $1,000 in principal amount of such notes, subject to certain conditions, or, into warrants to purchase an equal number of shares of Common Stock at an exercise price of $0.01 per share in order to facilitate the Company’s compliance with the provisions of the Jones Act. The Company bifurcated the embedded conversion option liability of $27.3 million from the Old Convertible Notes and recorded an additional debt discount (see “Note 8. Derivative Instruments and Hedging Strategies” and “Note 9. Fair Value Measurements”). The adjusted unamortized debt discount and issue costs of the Old Convertible Notes were amortized as additional non-cash interest expense over the remaining term of the debt for an overall effective interest rate of 7.95% and the changes in the fair value of the bifurcated derivative were recorded as derivative income or loss. On May 2, 2018, the Company and the Carlyle Investors entered into an exchange transaction (the “Exchange”) pursuant to which Carlyle Investors exchanged $50.0 million in principal amount of the Old Convertible Notes for Warrants to purchase 1,886,792 shares of Common Stock (to facilitate compliance with the provisions of the Jones Act) at an exercise price of $0.01 per share, subject to adjustments (the “Carlyle Warrants”), representing an implied exchange rate of approximately 37.73 shares per $1,000 in principal amount of the Old Convertible Notes (equivalent to an exchange price of $26.50 per share). The Carlyle Warrants have a 25-year term, which commenced May 2, 2018. The Company and Carlyle Investors also amended the $125.0 million in principal amount of Old Convertible Notes that remained outstanding following the Exchange to (i) increase the interest rate from 3.75% per annum to 4.25% per annum and (ii) extend the maturity date of the Old Convertible Notes by 12 months to December 1, 2023. The adjusted unamortized debt discount and issue costs of the Old Convertible Notes were amortized as additional non-cash interest expense over the remaining term of the debt for an overall effective interest rate of 9.29% and the changes in the fair value of the bifurcated derivative were recorded as derivative income or loss. On October 5, 2022, SEACOR Marine and the Carlyle Investors entered into two agreements pursuant to which SEACOR Marine issued the Carlyle Investors (i) $90.0 million in aggregate principal amount of the Company’s 8.0% / 9.5% Senior PIK Toggle Notes due 2026 (the “Guaranteed Notes”) and (ii) $35.0 million aggregate principal amount of SEACOR Marine’s 4.25% Convertible Senior Notes due 2026 (the “New Convertible Notes”) in exchange for all of SEACOR Marine’s Old Convertible Notes (the “Exchange Transactions”). During the year ended December 31, 2022, the Company recognized contractual interest expense of $4.0 million and amortization of debt discount and issue costs of $4.0 million, for total interest expense of $8.0 million. Guaranteed Notes. The Guaranteed Notes were issued pursuant to the Exchange Agreement (Guaranteed Notes) among SEACOR Marine, as issuer, Falcon Global Robert LLC, a wholly owned subsidiary of the Company (“FG Robert”), as the guarantor, and the Carlyle Investors (the “Guaranteed Notes Exchange Agreement”). Pursuant to the Guaranteed Notes Exchange Agreement, SEACOR Marine has the right to pay interest on the Guaranteed Notes (i) in cash at a rate of 8.0% per annum (“Cash Interest”) or (ii) partly in cash and partly in-kind by increasing the principal amount of the Guaranteed Notes or issuing additional Guaranteed Notes at a rate of 9.5% per annum (“Hybrid Interest”) with the cash portion of the Hybrid Interest bearing interest at a rate of 4.25% per annum and in the in-kind portion of the Hybrid Interest bearing interest at a rate of 5.25% per annum. The Guaranteed Notes mature on July 1, 2026. The Guaranteed Notes are guaranteed on a senior unsecured basis by FG Robert, the owner of the LB Robert liftboat. SEACOR Marine may redeem some or all of the Guaranteed Notes at any time in minimum denominations of $10.0 million, upon not less than 30 nor more than 60 calendar days’ notice, at a price equal to (a) 101% of the principal amount of the Guaranteed Notes redeemed, if redeemed prior to October 1, 2024 and (b) 100% of the principal amount of the Guaranteed Notes redeemed, if redeemed on or after October 1, 2024, in either case plus accrued and unpaid interest, if any, to, but not including, the redemption date, provided, SEACOR Marine may not redeem the Guaranteed Notes if the principal amount of Guaranteed Notes and New Convertible Notes outstanding will be equal to or less than $50.0 million in the aggregate, unless SEACOR Marine redeems all of the Guaranteed Notes in whole. The Guaranteed Notes Exchange Agreement contains certain customary covenants that among others, limit the ability of (i) SEACOR Marine and FG Robert to incur indebtedness, (ii) FG Robert to create or incur liens, (iii) SEACOR Marine to create liens on the ownership interest of FG Robert, (iv) FG Robert to sell assets, and (v) SEACOR Marine to sell the ownership interest of FG Robert, as well as customary representations and warranties made by SEACOR Marine, FG Robert and the Carlyle Investors and customary events of default. 95 New Convertible Notes. The New Convertible Notes were issued pursuant to the Exchange Agreement (Convertible Notes) among SEACOR Marine, as issuer, and the Carlyle Investors (the “Convertible Notes Exchange Agreement”). The New Convertible Notes bear interest at a rate of 4.25% per annum payable semi-annually in arrears and mature on July 1, 2026. The New Convertible Notes are convertible into shares of Common Stock at the option of the holders at a conversion rate of 85.1064 shares per $1,000 in principal amount of New Convertible Notes (equivalent to a “Conversion Price” of $11.75) or into warrants to purchase an equal number of shares of Common Stock at an exercise price of $0.01 per share in order to facilitate SEACOR Marine’s compliance with the provisions of the Jones Act. In addition, SEACOR Marine has the right to cause the mandatory conversion of the New Convertible Notes into Common Stock if the daily volume-weighted average price (“VWAP”) of the Common Stock equals or exceeds (A) in the case of New Convertible Notes held by affiliates of Carlyle, 150% of the Conversion Price and (B) in the case of New Convertible Notes held by any Person other than affiliates of Carlyle, 115% of the Conversion Price, in each case for each of the 20 consecutive trading days. If SEACOR Marine undergoes a Company Fundamental Change (as defined in the Convertible Notes Exchange Agreement), the holders of the New Convertible Notes may require SEACOR Marine to purchase for cash all or part of the New Convertible Notes at a price equal to 100% of the principal amount the New Convertible Notes to be purchased, plus accrued and unpaid interest to the date of purchase. The New Convertible Notes may be redeemed, in whole but not in part and only if certain conditions are met, as more fully described in the Convertible Notes Exchange Agreement, at a price equal to 100% of the principal amount of the New Convertible Notes to be redeemed, plus accrued and unpaid interest to the date of redemption. Under the Convertible Notes Exchange Agreement, the Carlyle Investors have the ability to nominate one director to the Board of Directors but currently do not exercise this right. The Convertible Notes Exchange Agreement contains customary representations and warranties made by SEACOR Marine and the Carlyle Investors and contains customary events of default and covenants. The conversion option of the New Convertible Notes qualified as an exception from the derivative accounting treatment under Accounting Standards Codification 815. Accordingly, the conversion option was not bifurcated and the debt was recorded at fair value. The adjusted unamortized debt discount and issue costs are being amortized as additional non-cash interest expense over the remaining term of the New Convertible Notes for an overall effective interest rate of 9.46%. As of December 31, 2023, the unamortized discount and issue costs were $3.7 million and $0.4 million, respectively, for a total net carrying amount of $30.9 million. In addition, during the year ended December 31, 2023, the Company recognized contractual interest expense of $2.9 million and amortization of debt discount and issue costs of $1.4 million, for total interest expense of $4.3 million. As of December 31, 2022, the unamortized discount and issue costs were $4.9 million and $0.6 million, respectively, for a total net carrying amount of $29.5 million. In addition, during the year ended December 31, 2022, the Company recognized contractual interest expense of $0.7 million and amortization of debt discount and issue costs of $0.3 million, for total interest expense of $1.0 million. 2023 SMFH Credit Facility. On September 8, 2023, SEACOR Marine, as parent guarantor, SEACOR Marine Foreign Holdings Inc. (“SMFH”), as borrower, and certain other wholly owned subsidiaries of SEACOR Marine, as subsidiary guarantors, entered into a credit agreement providing for a $122.0 million senior secured term loan (the “2023 SMFH Credit Facility”) with certain affiliates of EnTrust Global, as lenders, Kroll Agency Services, Limited, as facility agent, and Kroll Trustee Services Limited, as security trustee for the purposes of creating a more rational and efficient capital structure for the Company by consolidating a number of different credit facilities with different lending groups into a single facility. The proceeds of the 2023 SMFH Credit Facility were used to: (x) refinance approximately $104.8 million of existing principal indebtedness comprised of: (a) $61.1 million incurred under the 2018 SMFH Credit Facility (as defined below), (b) $11.0 million incurred under the SEACOR 88/888 Term Loan (as defined below), (c) $15.1 million incurred under the SEACOR OSV Credit Facility (as defined below), (d) $13.7 million incurred under the SEACOSCO Acquisition Debt (as defined below), and (e) $3.9 million incurred under the Tarahumara Shipyard Financing (as defined below), which payoff amount reflects a 7% discount to book value, (y) acquire 100% ownership of the Amy Clemons McCall, a 2014 built FSV, previously operated under lease and now pledged as collateral under the 2023 SMFH Credit Facility, and 96 (z) satisfy accrued and unpaid interest, fees, and general corporate purposes. The funds available under the 2023 SMFH Credit Facility were fully drawn on September 14, 2023. The 2023 SMFH Credit Facility matures on September 14, 2028, with quarterly amortization of 2.5% of the initial loan advanced thereunder, with the remaining outstanding principal amount due on the maturity date. The 2023 SMFH Credit Facility bears interest at a fixed rate of 11.75% per annum. The loan may be prepaid at any time in amounts of $1,000,000 or greater, subject to: (a) prior to the 12-month anniversary of funding, a premium equal to the remaining unpaid interest due over the first 15 months of the loan, and (b) after the 12-month anniversary of funding and prior to the 30-month anniversary of funding, a decreasing premium ranging from 3.00% to 1.00% of the amount prepaid. The 2023 SMFH Credit Facility contains customary covenants for financings of this type including financial maintenance and restrictive covenants, such as the aggregate collateral vessel value to the sum of the outstanding principal amounts of the loans. The 2023 SMFH Credit Facility restricts the payment of dividends and distributions and the ability of the borrower and subsidiary guarantors to make certain investments, subject to important exceptions. In addition, the 2023 SMFH Credit Facility includes customary events of default. SEACOR Marine issued a guaranty with respect to the obligations of the Borrower under the 2023 SMFH Credit Facility and related documents (the “2023 SMFH Credit Facility Guaranty”). The 2023 SMFH Credit Facility Guaranty includes, among other customary covenants, various financial covenants, including (A) minimum Cash and Cash Equivalents (as defined in the 2023 SMFH Credit Facility) of the greater of $20.0 million and 7.5% of Net Interest-Bearing Debt (as defined in the 2023 SMFH Credit Facility), (B) minimum Equity Ratio (as defined in the 2023 SMFH Credit Facility) of 35%, and (C) maximum Debt-to-Capitalization Ratio (as defined in the 2023 SMFH Credit Facility) of 65%. The Company was in compliance with all such covenants as of December 31, 2023. The 2023 SMFH Credit Facility Guaranty also restricts the payment of dividends and distributions and includes certain restrictions on the prepayment of unsecured indebtedness. During the year ended December 31, 2023, the Company expensed $1.8 million of payments for early terminations fees and $0.2 million of unamortized debt issue costs related to the debt extinguishment. 2018 SMFH Credit Facility.

SEACOR Alpine Credit Facility. On June 16, 2023, SEACOR Alps LLC (“SEACOR Alps”), SEACOR Andes LLC (“SEACOR Andes”), and SEACOR Atlas LLC (“SEACOR Atlas” and, together with SEACOR Alps and SEACOR Andes, the “SEACOR Alpine Borrowers”), each a wholly owned subsidiary of the Company, as borrowers, entered into a $28.0 million senior secured term loan facility, by and among the SEACOR Alpine Borrowers, SEACOR Marine, as a guarantor, SEACOR Marine Alpine LLC, a wholly owned subsidiary of the Company, and Mountain Supply LLC, an affiliate of Hudson Structured Capital Management, as lender, facility agent and security trustee (the “SEACOR Alpine Credit Facility”). The proceeds of the SEACOR Alpine Credit Facility were made available to the SEACOR Alpine Borrowers in three tranches and were used to satisfy in full amounts outstanding under the SEACOR Alpine Shipyard Financing (as defined below). The funds available under the SEACOR Alpine Credit Facility were fully drawn on June 27, 2023. The SEACOR Alpine Credit Facility matures on June 27, 2028 (the “SEACOR Alpine Maturity Date”). The principal amount of each of the three tranches of the SEACOR Alpine Credit Facility is to be repaid in monthly installments of (i) $100,000 for the first eight (8) installments, (ii) $140,000 for the following twenty-four (24) installments, and (iii) $100,000 for each installment thereafter until the SEACOR Alpine Maturity Date. The SEACOR Alpine Credit Facility bears interest at a fixed rate of 10.25% per annum. The loan may be prepaid at any time in amounts of $500,000 or greater, subject to the payment of prepayment interest in respect of the loan or tranche (or portions thereof) being prepaid as follows: (A) if such prepayment is made prior to the first anniversary of the drawdown date, an amount equal to the greater of (x) the amount of unpaid interest which would have accrued until the first anniversary of the drawdown date and (y) 1.5% of the principal amount of the loan being prepaid, (B) if such prepayment is made on or after the first anniversary of the drawdown date but prior to the third anniversary of the drawdown date, 1.0% of the principal amount of the loan being prepaid, and (C) if such prepayment is made on or after the third anniversary of the drawdown date, no prepayment interest shall be payable. The SEACOR Alpine Credit Facility contains customary covenants for financings of this type including financial maintenance and restrictive covenants, including the maintenance of certain ratios such as the aggregate collateral vessel value to the sum of the outstanding principal amounts of the loans. The SEACOR Alpine Credit Facility restricts the payment of dividends and distributions and the ability of the SEACOR Alpine Borrowers to make certain investments. In addition, the SEACOR Alpine Credit Facility includes customary events of default. In connection with the SEACOR Alpine Credit Facility, SEACOR Marine issued a guaranty with respect to the obligations of the SEACOR Alpine Borrowers under the SEACOR Alpine Credit Agreement and related documents. This guaranty includes, among other customary covenants, various financial covenants, including minimum liquidity, and debt-to-capitalization and interest coverage ratios. On September 8, 2023, SEACOR Marine entered into an amended and restated guaranty (“A&R SEACOR Alpine Credit Facility Guaranty”) with respect to the SEACOR Alpine Credit Facility. The A&R SEACOR Alpine Credit Facility Guaranty aligns the financial covenants and conditions relating to the payment of dividends and distributions reflected therein with those reflected in the 2023 SMFH Credit Facility Guaranty described above. SEACOR Alpine Shipyard Financing. In 2019, the Company committed to take possession of three Rolls Royce UT 771 CDL designed diesel electric powered PSVs of 3,800 tons delivered deadweight capacity with dynamic position class 2 and firefighting class 1 notations. As part of this transaction, the shipbuilder, COSCO Shipping Heavy Industry (Zhoushan) Co. Ltd., agreed to finance 70% of the cost of each of these vessels pursuant to a deferred payment agreement (the “SEACOR Alpine Shipyard Financing”). The SEACOR Alpine Shipyard Financing called for increasing quarterly payments of principal and interest payments that bear interest at a 98 fixed annual rate of 5% over a four-year term from delivery. The payment obligations were secured by a first priority mortgage on the three vessels acquired. The Company took delivery of the three vessels, namely the SEACOR Alps, the SEACOR Andes and the SEACOR Atlas on September 30, 2019, April 20, 2020 and August 10, 2020, respectively. Proceeds from the SEACOR Alpine Credit Facility were used to satisfy in full the SEACOR Alpine Shipyard Financing. SEACOSCO Acquisition Debt. On June 30, 2020, the Company completed the acquisition of the 50% membership interest in SEACOR Offshore Delta LLC, formerly known as SEACOSCO Offshore LLC (such remaining interests, the “SEACOSCO Interests”) that it did not already own. SEACOR Offshore Delta LLC is the owner of the eight SEACOR Delta PSVs. The price payable by the Company for the SEACOSCO Interests was $28.2 million (the “SEACOSCO Purchase Price”), $8.4 million of which was paid to the sellers (the “SEACOSCO Sellers”) at the closing. The deferred portion of the SEACOSCO Purchase Price was payable in annual installment payments of $1.0 million, $2.5 million and $2.5 million in the first, second and third year after the signing date of the acquisition, respectively, with the remaining $13.7 million due four years after such date (such deferred portion of the SEACOSCO Purchase Price, “SEACOSCO Acquisition Debt”). The SEACOSCO Acquisition Debt accrued interest at a fixed annual rate of 1.5%, 7.0%, 7.5% and 8.0% for the first through fourth years after the signing date, respectively. Proceeds from the 2023 SMFH Credit Facility were used to satisfy in full the SEACOSCO Acquisition Debt. SEACOR 88/888 Term Loan Facility. On July 5, 2018, SEACOR 88 LLC and SEACOR 888 LLC, each a wholly owned subsidiary of the Company, entered into a certain $11.0 million senior secured loan agreement with DNB Bank ASA, New York Branch and DNB Capital LLC (as amended, the “SEACOR 88/888 Term Loan”), and used the funds to acquire two AHTS vessels, the SEACOR 88 and SEACOR 888, that were previously managed (but not owned) by the Company. The SEACOR 88/888 Term Loan was secured by the SEACOR 88 and SEACOR 888 vessels, and SEACOR Marine provided a limited guaranty of such loan under which claims recoverable from SEACOR Marine shall not exceed the lesser of (x) $5.5 million and (y) 50% of the obligations outstanding at the time a claim is made thereunder. The SEACOR 88/888 Term Loan was amended on August 2, 2022 to provide for, among other things, (i) the extension of the maturity date of the SEACOR 88/888 Term Loan from June 29, 2023 to July 1, 2024, (ii) the change in the reference rate from LIBOR to SOFR and (iii) the amendment of the applicable annual interest rate margin over SOFR (previously LIBOR) from 3.75% to 4.75%. Proceeds from the 2023 SMFH Credit Facility were used to satisfy in full the SEACOR 88/888 Term Loan. Tarahumara Shipyard Financing. On July 9, 2021, SMLLC took delivery of the vessel named SEACOR Tarahumara, a 2021 built PSV. Effective upon such delivery and as partial consideration for the acquisition of the vessel, SMLLC entered into a loan agreement with Master Boat Builders, Inc. with respect to a term loan in the amount of $6.5 million. This term loan matures in 2025 with interest-only payments for the first year, with the loan fully amortizing on a straight-line basis over the remaining term. The term loan bears interest at a fixed annual rate of 6% and is secured by a first lien mortgage on the vessel. SMLLC is the sole borrower under the loan agreement (the “Tarahumara Shipyard Financing”). Proceeds from the 2023 SMFH Credit Facility were used to satisfy in full the Tarahumara Shipyard Financing, at a 7% discount to book value. SEACOR Offshore OSV. In connection with the OSV Partners Merger, completed on December 31, 2021, SEACOR Marine and SEACOR Offshore OSV assumed and guaranteed approximately $18.1 million of OSV Partners I’s third-party indebtedness outstanding under that certain second amended and restated credit facility agreement with DNB Capital LLC and Comerica Bank, as lenders, and administered by DNB Bank ASA, New York Branch, dated as of December 31, 2021 (as amended from time to time, the “SEACOR OSV Credit Facility”). The Company’s payment obligations under the SEACOR OSV Credit Facility were secured by a first lien mortgage on the five acquired vessels. On December 22, 2022, the SEACOR OSV Credit Facility was amended to provide for, among other things, the division of the loans under the SEACOR OSV Credit Facility into two tranches of debt, Class A Debt (as defined in the SEACOR OSV Credit Facility) deemed loaned under the SEACOR OSV Credit Facility by DNB Capital LLC in an amount of approximately $10.9 million as of the date of the amendment, and Class B Debt (as defined in the SEACOR OSV Credit Facility) deemed loaned under the SEACOR OSV Credit Facility by Comerica Bank in an amount of approximately $5.6 million as of the date of the amendment.

INCOME TAXES (Loss) Income before income tax expense (benefit) and equity in earnings (losses) of 50% or less owned companies derived from U.S. and foreign companies for the years ended December 31 were as follows (in thousands): United States Foreign Eliminations 2023 2022 2021 (3,576) $ (335) (160) (4,071) $ (48,037) $ (21,881) (160) (70,078) $ 34,955 (29,425) 1,097 6,627 $ $ The components of income tax expense (benefit) for the years ended December 31 were as follows (in thousands): Current: Federal State Foreign Deferred: Federal State Foreign 2023 2022 2021 $ $ (18) $ 47 13,831 13,860 (5,062) 8 (7) (5,061) 8,799 $ 90 (78) 8,473 8,485 7 90 — 97 8,582 $ $ — 271 6,362 6,633 4,892 (32) — 4,860 11,493 100 The following table reconciles the difference between the statutory federal income tax rate for the Company and the effective income tax rate for the years ended December 31: Statutory rate Income (loss) of foreign subsidiaries not includable in U.S. return and foreign withholding tax Non-Deductible Expenses JV equity earnings Sale of investments in 50% or less owned companies 162(m) - Executive compensation Return to provision State Taxes Subpart F Income Share Award Plans Other Effective Tax Rate 2023 2022 2021 (21.0)% 223.4% 1.2% —% —% 17.8% —% 1.1% 6.6% (12.9)% — 216.2% (21.0)% 20.8% 0.3% —% 11.1% —% —% —% 0.7% 0.3% 0.1% 12.3% 21.0% 141.6% 0.4% 3.8% —% —% 0.4% 2.7% 2.0% 1.5% —% 173.4% For the year ending December 31, 2023, the Company’s effective income tax rate of 216.2% was primarily due to foreign withholding taxes. For the year ending December 31, 2022, the Company’s effective income tax rate of 12.3% was primarily due to foreign taxes paid that are not creditable against U.S. income taxes, foreign losses for which there is no benefit in the U.S. and the sale of investments in 50% or less owned companies. For the year ending December 31, 2021, the Company’s effective income tax rate of 173.4% was primarily due to foreign taxes not creditable against U.S. income taxes and foreign subsidiaries with current losses for which there is no current or future federal income tax benefit. The components of net deferred income tax liabilities as of December 31 were as follows (in thousands): Deferred tax liabilities: Property and equipment Other Total deferred tax liabilities Deferred tax assets: Federal Net Operating Loss Carryforwards Other Valuation Allowance Total deferred tax assets Net deferred tax liabilities 2023 2022 48,779 3,533 52,312 10,887 10,632 21,519 (4,925) 16,594 35,718 $ $ 56,618 6,094 62,712 14,822 9,619 24,441 (2,508) 21,933 40,779 $ $ The Section 163(j) interest deduction limitations were amended to limit the ability of the Company to deduct net interest expense to 30% of adjusted taxable income.

Net operating losses generated in 2017 and prior may be carried forward 20 years (expiring in 2037). Future utilization of net operating losses (“NOL”) arising in tax years after December 31, 2017 are limited to 80% of taxable income and are allowed to be carried forward indefinitely. As of December 31, 2023, the Company has utilized all of its remaining net operating losses generated prior to December 31, 2017, and has $51.8 million of net operating losses generated after 2017.

DERIVATIVE INSTRUMENTS AND HEDGING STRATEGIES Derivative instruments are classified as either assets, which are included in other receivables in the accompanying consolidated balance sheets, or liabilities based on their individual fair values. The fair values of the Company’s derivative instruments as of December 31 were as follows (in thousands): Derivatives designated as hedging instruments: Interest rate swap agreements (cash flow hedges) Derivatives not designated as hedging instruments: Forward Exchange Contract 2023 2022 Derivative Asset Derivative Liability Derivative Asset Derivative Liability $ $ — $ — $ 526 $ 608 $ — $ — $ — — Economic Hedges. The Company may enter and settle forward currency exchange, option and future contracts with respect to various foreign currencies. These contracts enable the Company to buy currencies in the future at fixed exchange rates, which could offset possible consequences of changes in currency exchange rates with respect to the Company’s business conducted outside of the U.S. The Company generally does not enter into contracts with forward settlement dates beyond 12 to 18 months. During the fourth quarter of 2023, the Company entered into a forward exchange contract related to the purchase of hybrid battery power systems. During the years ended December 31, 2023 and December 31, 2021, the Company recognized gains of $0.6 million and $0.4 million, respectively, on these contracts which were recognized concurrently in earnings. As of December 31, 2022, the Company had no open forward currency exchange contracts. Cash Flow Hedges. The Company may from time to time enter into interest rate swap agreements designated as cash flow hedges. By entering into interest rate swap agreements, the Company can convert the variable interest component of certain of their outstanding borrowings to a fixed interest rate. The Company recognized losses on derivative instruments designated as cash flow hedges of $0.5 million for the year ended December 31, 2023 and gains of $2.3 million for the years ended December 31, 2022 and 2021 as a component of other comprehensive income (loss). As of December 31, 2023, there were no interest rate swaps held by the Company. Derivative Instruments. The Company utilizes derivative instruments to manage the volatility of cash flows due to fluctuating interest rates. All derivative instruments not qualifying for the normal purchase and normal sale exception are recorded on the balance sheets at fair value. The treatment of the periodic changes in fair value will depend on whether the derivative is designated and effective as a hedge for accounting purposes. If a derivative qualifies for hedge accounting and is designated as a cash flow hedge, the effective portion of the change in fair value of the derivative is deferred in Accumulated Other Comprehensive Income (“AOCI”), a component of owners’ equity, and reclassified to earnings when the forecasted transaction occurs. Cash flows from a derivative instrument designated as a hedge are classified in the same category as the cash flows from the item being hedged. As such, we include the cash flows from interest rate derivative instruments in interest expense. If a derivative does not qualify as a hedge or is not designated as a hedge, the gain or loss resulting from the change in fair value on the derivative is recognized currently in earnings as a component of other income (expense). We formally document all relationships between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking the hedge. This documentation includes the specific identification of the hedging instrument and the hedged item, the nature of the risk being hedged and the manner in which the hedging instrument’s effectiveness will be assessed. At the inception of the hedge, and on an ongoing basis, we assess whether the derivatives used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. The relationship between the hedging instrument and the hedged item must be highly effective in achieving the offset of changes in cash flows attributable to the hedged risk both at the inception of the contract and on an ongoing basis. We measure hedge ineffectiveness on a quarterly basis and reclassify any ineffective portion of the gain or loss related to the change in fair value to earnings in the current period. We will discontinue hedge accounting on a prospective basis when a hedge instrument is terminated or ceases to be highly effective. Gains and losses deferred in AOCI related to cash flow hedges for which hedge accounting has been discontinued remain deferred until the forecasted transaction occurs. If it is no longer probable that a hedged forecasted transaction will occur, deferred gains or losses on the hedging instrument are reclassified to earnings immediately. 102 For balance sheet classification purposes, we analyze the fair values of the derivative instruments on a contract-by-contract basis and report the related fair values and any related collateral by counterparty on a gross basis. Realized and unrealized gains and losses on derivatives designated as cash flow hedges that are entered into by the Company’s 50% or less owned companies are also reported as a component of the Company’s other comprehensive loss in proportion to the Company’s ownership percentage, with reclassifications and ineffective portions being included in equity in earnings (losses) of 50% or less owned companies, net of tax, in the accompanying consolidated statements of income (loss). The fair value of our derivative instruments, depending on the type of instrument, is determined by the use of present value methods or standard option valuation models with assumptions about commodity prices based on those observed in underlying markets. The estimated fair value is net of an adjustment for credit risk based on the default probabilities by year as indicated by market quotes for the counterparties’ credit default swap rates. The following tables reflect amounts recorded in Other Comprehensive Income (Loss) (“OCI”) and amounts reclassified from OCI to revenue and expense for the periods indicated: Derivatives in Cash Flow Hedging Relationships Interest rate swap contracts Joint venture interest rate swap contracts Location of (Gains) Losses Interest expense Gains (Losses) Recognized in OCI on Derivatives (Effective Portion) 2022 2023 2021 $ $ 56 — 1,608 941 $ 219 (588) (Gains) Losses Reclassified from OCI into Income (Effective Portion) 2022 2021 2023 $ (571) $ 694 $ 1,648 Our consolidated earnings are also affected by the use of the mark-to-market method of accounting for derivative instruments that do not qualify for hedge accounting or that have not been designated as hedges. The changes in fair value of these instruments are recorded on the balance sheet and through earnings rather than being deferred until the anticipated transaction settles. The use of mark-to- market accounting for financial instruments can cause non-cash earnings volatility due to changes in the underlying commodity price indices. Other Derivative Instruments. The Company recognized gains on derivative instruments not designated as hedging instruments for the years ended December 31 as follows (in thousands): Conversion option liability on Old Convertible Notes Forward currency exchange, option and future contracts Derivative gains (losses), net 2022 2021 2023 $ $ — $ 608 608 $ — $ — — $ 2 390 392 The conversion option liability related to the bifurcated embedded conversion option in the Old Convertible Notes, issued to investment funds managed and controlled by Carlyle, was exchanged for the New Convertible Notes (see “Note 6. Long-Term Debt”). The forward currency exchange contract in 2023 relates to the purchase of hybrid battery power systems. The forward currency exchange contract in 2021 relates to £31.5 million swap related to the proceeds received from the sale of Windcat Workboats (see “Note 3. Equipment Acquisitions and Dispositions”). 9. 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.

SAVINGS AND MULTI-EMPLOYER PENSION PLANS Noncontrolling Interests 2023 2022 1.8% $ 321 $ 321 SEACOR Marine Savings Plan. On January 1, 2016, the Company’s eligible U.S. based employees were transferred from the SEACOR Holdings sponsored defined contribution plan to the “SEACOR Marine 401(k) Plan,” a new Company sponsored defined contribution plan (the “Savings Plan”). Effective upon the June 1, 2017 spin-off from SEACOR Holdings, the Company discontinued its contribution to the Savings Plan up until January 1, 2019, at which time the Company’s contribution were limited to 1% of an employee’s wages. In 2020, the Company increased its matching contributions to 2% of an employee’s wages. Effective January 1, 2022, the Company increased its matching contributions to 3% of an employee’s wages and effective July 1, 2022 the Company increased such contribution to 4%. The Savings Plan costs for the years ended December 31, 2023, 2022 and 2021 were $1.1 million, $0.8 million and $0.2 million, respectively. MNOPF and MNRPF. Certain of the Company’s subsidiaries are participating employers in two industry-wide, multi- employer, defined benefit pension funds in the United Kingdom (“U.K.”): 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 December 31, 2023, all invoices received related to MNOPF and MNRPF have been settled in full. On October 19, 2021, the Company was informed by the MNRPF that two issues had been identified during a review of the MNRPF by the applicable trustee that would potentially give rise to material additional liabilities for the MNRPF. On November 23, 2023, the trustee advised that following the tri-annual valuation, $1.5 million (£1.2 million) of the potential cumulative funding deficit of the MNRPF was allocated to the Company as a participating employer, including the additional liabilities mentioned above. During 2023, the Company recognized payroll related operating expenses of $1.5 million (£1.2 million) for its allocated share of the potential cumulative funding deficit, which the Company will be invoiced for during 2024 and 2025. Other Plans. Certain employees participate in other defined contribution plans in various international regions. During the years ended December 31, 2023, 2022 and 2021, the Company incurred costs, primarily from employer matching contributions of $0.7 million, $0.3 million and $0.4 million, respectively. 14. STOCK BASED COMPENSATION Equity Incentive Plan. During 2017, the Company adopted the SEACOR Marine Holdings Inc. 2017 Equity Incentive Plan (the “2017 Plan”) and at the annual meeting of shareholders held on June 9, 2020, the Company’s shareholders approved the SEACOR Marine Holdings Inc. 2020 Equity Incentive Plan (the “2020 Plan”). At the annual meeting of shareholders held on June 7, 2022 (the “Approval Date”), the Company’s shareholders approved the SEACOR Marine Holdings Inc. 2022 Equity Incentive Plan (the “2022 Plan”), which authorized the issuance of 2,450,000 shares of Common Stock under the 2022 Plan plus 6,005 shares of Common Stock remaining available for issuance under the 2020 Plan as of the Approval Date that will be available for issuance under the 2022 Plan. The types of awards under the 2022 Plan may include stock options, stock appreciation rights, restricted stock and restricted stock units, performance awards and other stock-based awards. As of December 31, 2023, 1,812,963 shares of Common Stock remained available for issuance under the 2022 Plan. 106 Restricted stock typically vests from one to four years after the date of grant, and stock options to purchase shares of Common Stock typically vest and become exercisable from one to four years after date of grant and expire no later than the tenth anniversary of the date of grant for both employees and directors. Performance restricted stock units (“PRSUs”) typically vest on a cliff-basis after three years, subject to certain stock price performance goals. Pursuant to the applicable award agreements, restricted stock and stock options vest subject to the participant’s continued employment with the Company on the applicable vesting date, subject to accelerated vested upon the executive’s death or qualified retirement or, with respect to restricted stock, upon termination by the Company without “cause” (including for disability). Upon any such termination, PRSUs that have been earned with respect to the stock price performance goal(s) will be settled on the third anniversary of the grant date, without regard to the participants employment with the Company as of such date. For options granted, the fair value is estimated on the date of the grant using the Black-Scholes option pricing model with the following assumptions: (a) no dividend yield; (b) weighted average expected volatility; (c) weighted average discount rate; and (d) expected life. The fair value of restricted stock, earned PRSUs and stock options issued to employees and directors, as applicable, is recognized as compensation expense over the period of service that generally coincides with the vesting period of the award. For all award types, forfeitures are recognized as incurred. Distribution of SEACOR Marine Restricted Stock by SEACOR Holdings. Certain officers and employees of the Company previously received compensation through participation in SEACOR Holdings share award plans. Pursuant to the Employee Matters Agreement with SEACOR Holdings, participating Company personnel vested in all outstanding SEACOR Holdings share awards upon the spin-off in 2017 and received SEACOR Marine restricted stock from the spin-off distribution in connection with outstanding SEACOR Holdings restricted stock held. The Company paid SEACOR Holdings $2.7 million upon completion of the spin-off for the distribution of 120,693 shares of SEACOR Marine restricted stock, which was fully amortized as of December 31, 2022. Employee Stock Purchase Plan. During 2017, the Company adopted the SEACOR Marine Holdings Inc. 2017 Employee Stock Purchase Plan (the “Marine ESPP”). The Marine ESPP, if implemented by the Board of Directors, will permit the Company to offer shares of its Common Stock for purchase by eligible employees at a price equal to 85% of the lesser of (i) the fair market value of a share of its Common Stock on the first day of the offering period or (ii) the fair market value of a share of its Common Stock on the last day of the offering period. There are 300,000 shares of the Company’s Common Stock reserved for issuance under the Marine ESPP during the ten years following its adoption. Share Award Transactions.

The Related Party Transactions Policy supplements the Company’s other conflict of interest policies set forth in the Company’s Corporate Governance Guidelines, its Code of Business Conduct and Ethics and its other internal procedures. Transactions with SEACOR Holdings 108 On June 26, 2020, the Company entered into the Tax Refund Agreement with SEACOR Holdings, the Company’s former parent company. The Tax Refund Agreement enabled the Company to utilize NOL generated in 2018 and 2019 to claim refunds for tax years prior to the Company’s spin-off from SEACOR Holdings in 2017 (at which time the Company was included in SEACOR Holdings consolidated tax returns) that were permitted to be carried back pursuant to the provisions of the CARES Act and for which SEACOR Holdings needed to claim the refund on behalf of the Company. As a result, the Company received an aggregate amount of cash tax refunds of $32.3 million (including $1.1 million of interest paid by the IRS in respect of refund payment delays due in part to the COVID-19 pandemic), of which $12.5 million was received prior to March 31, 2021 and the remaining $19.8 million was received in April 2021. SEACOR Holdings will retain certain of the funds to facilitate tax savings realized by SEACOR Holdings of no less than 35% of the amount of its own 2019 NOL. Additionally, a $3.0 million transaction fee was paid to SEACOR Holdings concurrently with the signing of the Tax Refund Agreement as consideration for its cooperation in connection with the filing of the applicable tax refund returns. The Tax Refund Agreement did not restrict the use of approximately $23.1 million of the refund and required the remaining approximately $8.1 million to be deposited into an account to be used solely to satisfy certain of the Company’s obligations that remained guaranteed by SEACOR Holdings which primarily related to vessel operating leases. Two of these vessel operating leases expired in the fourth quarter of 2020, which reduced the remaining guarantee on the three remaining vessels to $7.0 million. The remaining three vessel operating leases that SEACOR Holdings guaranteed expired in 2021 and the Company applied the amount deposited to satisfy these obligations. Transactions regarding OSV Partners OSV Partners. In 2013, OSV Partners I was formed to own and operate offshore support vessels with the Company (then a subsidiary of SEACOR Holdings) holding 30.4% of the initial limited partner interests (“Initial LP Interests”) and a majority of the general partner interests, and the remaining Initial LP Interests held by unrelated third parties. The Company was also appointed the manager of the vessels owned by OSV Partners I entitled to a market management fee. In December 2014, Charles Fabrikant (a former Non-Executive Chairman of SEACOR Marine), John Gellert (President, Chief Executive Officer and Director of SEACOR Marine), Jesús Llorca (Executive Vice President and Chief Financial Officer of SEACOR Marine) and other individuals (some of who were affiliated with the Company’s former parent, SEACOR Holdings), invested in Caroline International Holdings LLC (“Caroline”) and Caroline International Holdings II LLC (“Caroline II” and together with Caroline, the “Caroline Entities”), two entities managed by Mr. Fabrikant and formed solely for the purposes of investing in OSV Partners I. As of December 31, 2021, the aggregate investments of Messrs. Fabrikant, Gellert and Llorca in the Caroline Entities were $0.3 million, $0.4 million and $0.2 million, respectively. No other current executive officer or member of the Board of Directors invested in or has any interests in the Caroline Entities.

Beginning in January 2019, the Company agreed not to charge OSV Partners I the management fee it was contractually entitled to through December 31, 2021 due to continuing liquidity issues of OSV Partners I. For the years ended December 31, 2018 and 2017, the Company received $0.6 million of vessel management fees from OSV Partners I for each year. On October 29, 2021, in exchange for $2.2 million, the Company acquired from a third party lender approximately $4.1 million of the $22.1 million of principal owed under OSV Partner I’s amended and restated senior secured term loan credit facility agreement dated as of September 28, 2018 (the “SEACOR OSV Credit Facility” and such acquisition, the “First Lien Debt Acquisition”). OSV Partners Merger. On December 31, 2021, pursuant to the OSV Partners Merger Agreement OSV Partners I merged with and into SEACOR Offshore OSV with SEACOR Offshore OSV surviving the OSV Partners Merger. In connection with the consummation of the OSV Partners Merger, the Company issued an aggregate of 1,567,935 shares of Common Stock to the limited partners of OSV Partners I as follows: 109 (i) (ii) 531,872 shares of Common Stock as consideration for the OSV Partners Merger (“Merger Consideration”), 80% of which was paid in respect of Preferred Interests and Class A Preferred Interests, and 20% in respect of the Initial LP Interests partners (other than the Company and its subsidiaries); and 1,036,063 shares of Common Stock as consideration to settle all amounts outstanding under the PIK Loan Agreement (“PIK Loan Consideration”). In connection with the consummation of the OSV Partners Merger, (i) Caroline received an aggregate number of 73,107 shares of Common Stock and (ii) Caroline II received an aggregate of 36,570 shares of Common Stock.

In addition, a trust of which Mr. Gellert is one of several beneficiaries received an aggregate number of 26,557 shares of Common Stock. In connection with the OSV Partners Merger, the Company and SEACOR Offshore OSV assumed and guaranteed approximately $18.1 million of indebtedness outstanding under the SEACOR OSV Credit Facility. The First Lien Debt Acquisition and the OSV Partners Merger were subject to the oversight and received advance approval of the Audit Committee of the Board of Directors (“Audit Committee”) as related party transactions under the Company’s Related Party Transaction Policy. Mr. Gellert recused himself from deliberations by the Audit Committee and ultimately the Board of Directors with respect to the Merger, and the Board of Directors received a third party fairness opinion with respect thereto. Mr. Llorca was also not involved in the related discussions. Mr. Fabrikant no longer served on the Board of Directors as of June 8, 2021 and therefore had no participation in any of the approval processes for these transactions. Transactions with Carlyle Old Convertible Notes. On October 5, 2022, SEACOR Marine and the Carlyle Investors entered into two agreements pursuant to which SEACOR Marine issued the Carlyle Investors (i) $90.0 million in aggregate principal amount of the Guaranteed Notes and (ii) $35.0 million aggregate principal amount of the New Convertible Notes in exchange for all $125.0 million in aggregate principal amount of SEACOR Marine’s Old Convertible Notes outstanding.

SEACOR Marine may redeem some or all of the Guaranteed Notes at any time in minimum denominations of $10.0 million, upon not less than 30 nor more than 60 calendar days’ notice, at a price equal to (a) 101% of the principal amount of the Guaranteed Notes redeemed, if redeemed prior to October 1, 2024 and (b) 100% of the principal amount of the Guaranteed Notes redeemed, if redeemed on or after October 1, 2024, in each case plus accrued and unpaid interest, if any, to, but not including, the redemption date, provided, SEACOR Marine may not redeem the Guaranteed Notes if the principal amount of Guaranteed Notes and New Convertible Notes outstanding will be equal to or less than $50.0 million in the aggregate, unless SEACOR Marine redeems all of the Guaranteed Notes in whole. The Guaranteed Notes Exchange Agreement contains certain customary covenants that among others, limit the ability of (i) SEACOR Marine and FG Robert to incur indebtedness, (ii) FG Robert to create or incur liens, (iii) SEACOR Marine to create liens on the ownership interest of FG Robert, (iv) FG Robert to sell assets, and (v) SEACOR Marine to sell the ownership interest of FG Robert, as well as customary representations and warranties made by SEACOR Marine, FG Robert and the Carlyle Investors and customary events of default. 110 New Convertible Notes. The New Convertible Notes were issued pursuant to the Exchange Agreement (Convertible Notes) among SEACOR Marine, as issuer, and the Carlyle Investors. The New Convertible Notes bear interest at a rate of 4.25% per annum payable semi-annually in arrears and mature on July 1, 2026. The New Convertible Notes are convertible into shares of Common Stock at the option of the holders at a conversion rate of 85.1064 shares per $1,000 in principal amount of New Convertible Notes (equivalent to a “Conversion Price” of $11.75) or into warrants to purchase an equal number of shares of Common Stock at an exercise price of $0.01 per share in order to facilitate SEACOR Marine’s compliance with the provisions of the Jones Act. In addition, SEACOR Marine has the right to cause the mandatory conversion of the New Convertible Notes into Common Stock if the daily VWAP of the Common Stock equals or exceeds (A) in the case of New Convertible Notes held by affiliates of Carlyle, 150% of the Conversion Price and (B) in the case of New Convertible Notes held by any Person other than Carlyle, 115% of the Conversion Price, in each case for each of the 20 consecutive trading days. If SEACOR Marine undergoes a Company Fundamental Change (as defined in the Convertible Notes Exchange Agreement), the holders of the New Convertible Notes may require SEACOR Marine to purchase for cash all or part of the New Convertible Notes at a price equal to 100% of the principal amount the New Convertible Notes to be purchased, plus accrued and unpaid interest to the date of purchase. The New Convertible Notes may be redeemed, in whole but not in part and only if certain conditions are met, as more fully described in the Convertible Notes Exchange Agreement, at a price equal to 100% of the principal amount of the New Convertible Notes to be redeemed, plus accrued and unpaid interest to the date of redemption. Under the Convertible Notes Exchange Agreement, the Carlyle Investors have the ability to nominate one director to the Board of Directors if the Carlyle Investors, solely as a result of their ownership of shares of Common Stock owned by the Investors as of October 5, 2022 and ownership of the New Convertible Notes and warrants (including the shares of common stock of the Company issuable upon conversion or exercise thereof), beneficially own collectively 10% or more of the outstanding shares of common stock of the Company. The Carlyle Investors have not exercised this right. Ms. Anna Mire has been designated by the Carlyle Investors to observe meetings of the Board of Directors pursuant to the Carlyle Investors’ observer rights under the Convertible Notes Exchange Agreement and the Guaranteed Notes Exchange Agreement. This observation right will terminate at the time the Carlyle Investors own less than $50.0 million in aggregate principal amount of the New Convertible Notes and Guaranteed Notes or a combination of the New Convertible Notes and our Common Stock representing less than 5.0% of the Company’s Common Stock outstanding on a fully diluted basis, assuming the conversion of all of the New Convertible Notes and warrants to purchase Common Stock held by the Carlyle Investors. The Convertible Notes Exchange Agreement contains customary representations and warranties made by SEACOR Marine and the Carlyle Investors and contains customary events of default and covenants. The Convertible Notes Exchange Agreement and the transactions contemplated thereby were subject to the oversight of, and received advance approval from, the Audit Committee. During 2023 and 2021, the Carlyle Investors exercised 135,150 and 48,809 warrants, respectively. During 2022, the Carlyle Investors did not exercise any warrants. As of December 31, 2023, the Carlyle Investors had 1,304,333 outstanding warrants. Transactions with CME Mr. Alfredo Miguel Bejos, a member of the Board of Directors, currently serves as President and Chief Executive Officer of CME. In accordance with the Related Transaction Policy, the Audit Committee has adopted guidelines for addressing ongoing CME- related transactions. On December 20, 2018, MEXMAR Offshore, a joint venture that was 49.0% owned by a subsidiary of the Company and 51.0% owned by a subsidiary of CME, acquired UP Offshore. UP Offshore was acquired for nominal consideration. In connection with the acquisition, UP Offshore’s existing debt was refinanced with $95.0 million of new indebtedness composed of (i) a $70.0 million six- year debt facility provided by UP Offshore’s existing lenders that is non-recourse to the Company, CME or any of their respective subsidiaries, (ii) a $15.0 million loan from MexMar, a joint venture between CME and the Company, to fund capital expenditures on two vessels and (iii) a $10.0 million loan from MEXMAR Offshore to fund working capital requirements funded by an approximate $5.0 million capital contribution to MEXMAR Offshore by each of the Company and CME. Due to losses from equity earnings, the Company’s investment in MEXMAR Offshore was written down to $0 in 2019. In July 2020, MEXMAR Offshore purchased from a consortium of banks in Brazil, $70.0 million of UP Offshore’s debt for $5.5 million, of which the Company’s commitment was $2.7 million to fund this purchase. As of December 31, 2020, the Company had loaned its proportional share of this commitment to MEXMAR Offshore of $1.96 million. The Company funded its remaining commitment in February 2021. On June 1, 2021, MEXMAR Offshore completed the sale of eight vessels and certain Brazilian entities to OceanPact Serviços Marítimos S.A. and its subsidiary, OceanPact Netherlands B.V., for a total purchase price of $30.2 million (the “UP Offshore Sale Transaction”), which resulted in an equity earnings gain from 50% or less owned companies of $2.6 million. On July 23, 2021, the Company received a distribution from MEXMAR Offshore in the amount of $12.0 million of which $9.4 million was in excess of the Company’s investment balance of $2.6 million. The excess was recorded by the Company as a gain from return of investments in 50% or less owned companies. 111 After giving effect to the UP Offshore Sale Transaction, MEXMAR Offshore, indirectly through certain subsidiaries of UP Offshore, retained ownership of three vessels. As part of the winddown of the MEXMAR Offshore joint venture, ownership of two of these vessels was transferred from subsidiaries of UP Offshore to OVH on October 26, 2021, and the remaining vessel was transferred from a subsidiary of UP Offshore to OVH on November 2, 2021. Upon completion of these transactions, MEXMAR Offshore no longer held income producing assets and as a result, on December 9, 2021, the Company transferred its 49% interest in MEXMAR Offshore to a subsidiary of CME for nominal consideration and a transaction fee of $0.2 million. As of December 31, 2021, the Company does not have any ownership interest in MEXMAR Offshore. Prior to the consummation of the Framework Agreement Transactions described below, the Company also participated in a variety of other joint ventures with CME, including MexMar, SEACOR Marlin LLC and OVH. The joint venture agreements for each of these joint ventures were negotiated at arms-length in the ordinary course of business. MexMar is a joint venture company that was 49% owned by a wholly owned subsidiary of the Company and 51% owned by subsidiaries of CME. SEACOR Marlin LLC was a joint venture company that was 49% owned by a wholly owned subsidiary of the Company and 51% owned by a wholly owned subsidiary of MexMar. During the year ended December 31, 2021, there was a distribution to the Company from SEACOR Marlin LLC of $2.5 million. OVH is a joint venture company that is 49% owned by a wholly owned subsidiary of the Company and 51% owned by a subsidiary of CME. On December 10, 2021, OVH and OPEM settled the $10.0 million loan in exchange for OPEM making an early repayment of $10.5 million, reflecting repayment of the principal amount in full and a prepayment discount and forgiveness of approximately $4.1 million of accrued interest. On September 29, 2022, SEACOR Marine and certain of its subsidiaries, on the one hand, and OTM, CME Ireland, and OVH, on the other hand, entered into the Framework Agreement. OTM and CME Ireland are affiliates of CME. Prior to the closing of the Framework Agreement Transactions, the Company owned 49% of each of MexMar and OVH through SEACOR Marine International, a wholly owned subsidiary of the Company, and the remaining 51% ownership interests were held by OTM. The Company also owned a minority interest in SEACOR Marlin LLC, the owner of the PSV SEACOR Marlin, and the remaining ownership interests of SEACOR Marlin LLC were held by MexMar. The Framework Agreement provided for, among other things, (i) the sale by the Company of all of the outstanding equity interests of SEACOR Marine International to OTM for a purchase price of $66.0 million, (ii) the sale by the Company of the AHTS SEACOR Davis to CME Ireland in exchange for the remaining equity interests in SEACOR Marlin LLC, such that SEACOR Marlin LLC would become a wholly owned subsidiary of the Company, (iii) the transfer of a hybrid battery power system from OVH to the Company as repayment in full of a certain vessel loan agreement by the Company to its former joint venture, and (iv) entry into a bareboat charter agreement between SEACOR Marlin LLC and MexMar. Each of the Framework Agreement Transactions was consummated on September 29, 2022. As a result of the Framework Agreement Transactions, the Company no longer owns any equity interest in either of MexMar or OVH, and the Company owns all of the equity interests in SEACOR Marlin LLC, which owns the PSV SEACOR Marlin. In connection with the closing of the Framework Agreement Transactions, on September 29, 2022, SEACOR Marine Capital, a wholly owned subsidiary of SEACOR Marine, purchased all of the outstanding loans under the Second Amended and Restated Term Loan Credit Facility Agreement, made as of July 8, 2022, by and among MexMar, as the borrower, DNB Capital LLC and The Governor and Company of the Bank of Ireland, each as lenders, and DNB Bank ASA, New York Branch, as facility agent (as amended from time to time, the “MexMar Original Facility Agreement”) for an aggregate amount of $28.8 million, representing par value of the loan. The purchase was funded using proceeds received from the Framework Agreement Transactions. On the same date the facility was amended pursuant to a Third Amended and Restated Facility Agreement (“MexMar Third A&R Facility Agreement”) to, among other things, (i) provide for the prepayment by MexMar of approximately $8.8 million of the outstanding loan amount, to reduce the outstanding principal on the loan to $20.0 million, (ii) modify the definition of “Change of Control”, (iii) modify the maturity date from January 23, 2025 to September 30, 2023, (iv) decrease the minimum cash requirement from $10.0 million to $2.5 million, (v) modify the interest margin from 4.7% per annum to 5.0% per annum and (vi) modify the principal repayment profile to reflect four quarterly installments of $5.0 million to repay the loan by the maturity date. All collateral and security arrangements remained in place from the MexMar Original Facility Agreement, including a first priority mortgage on 13 offshore support vessels owned by MexMar. As a result, SEACOR Marine Capital was the sole lender to MexMar under the MexMar Third A&R Facility Agreement. This loan was repaid in full as of September 30, 2023. Each of the Framework Agreement Transactions and the transactions entered into in connection with the MexMar Third A&R Facility Agreement (the “MexMar Facility Agreement Transactions”) were subject to the oversight of, and received advance approval from, the Audit Committee as related party transactions subject to the Company’s Related Party Transaction Policy. Mr. Miguel recused himself from the Audit Committee and the Board of Directors deliberations with respect to the Framework Agreement Transactions and the Mexmar Facility Agreement Transactions. The Board of Directors received a third party fairness opinion with respect to the Framework Agreement Transactions. 16. COMMITMENTS AND CONTINGENCIES As of December 31, 2023, the Company had unfunded capital commitments of $15.5 million for miscellaneous vessel equipment, including hybrid battery power systems. Of the unfunded capital commitments, $13.5 million is payable during 2024 and $2.0 million is payable during 2025. The Company has indefinitely deferred an additional $9.2 million of capital commitments with respect to one FSV. 112 In December 2015, the Brazilian Federal Revenue Office issued a tax-deficiency notice to Seabulk Offshore do Brasil Ltda, a wholly owned subsidiary of the Company (“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 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$23.5 million based on a historical potential levy of R$12.87 million (USD $4.8 million and USD $2.7 million, respectively, based on the exchange rate as of December 31, 2023). In the normal course of its business, the Company becomes involved in various 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 December 31, 2023, all invoices received related to MNOPF and MNRPF have been settled in full. On October 19, 2021, the Company was informed by the MNRPF that two issues had been identified during a review of the MNRPF by the applicable trustee that would potentially give rise to material additional liabilities for the MNRPF. On November 23, 2023, the trustee advised that following the tri-annual valuation, $1.5 million (£1.2 million) of the potential cumulative funding deficit of the MNRPF was allocated to the Company as a participating employer, including the additional liabilities mentioned above. During 2023, the Company recognized payroll related operating expenses of $1.5 million (£1.2 million) for its allocated share of the potential cumulative funding deficit, which the Company will be invoiced for during 2024 and 2025. 17. MAJOR CUSTOMERS AND SEGMENT INFORMATION During the year ended December 31, 2023, ExxonMobil Corporation (“ExxonMobil”), SEACOR Marine Arabia, a joint venture of which the Company owns 45% and through which vessels are in service to Saudi Arabian Oil Company, and Azule Energy Angola S.p.A., a joint venture between BP p.l.c. and Eni S.p.A., were responsible for $47.7 million or 17%, $43.2 million or 15% and $42.4 million or 15%, respectively, of the Company’s total consolidated operating revenues from continuing operations. During the year ended December 31, 2022, ExxonMobil and SEACOR Marine Arabia were responsible for $39.6 million or 18% and $30.1 million or 14%, respectively, of the Company’s total consolidated operating revenues from continuing operations. During the year ended December 31, 2021, ExxonMobil and SEACOR Marine Arabia were each responsible for $35.2 million or 21% and $29.7 million or 17%, respectively, of the Company’s total consolidated operating revenues from continuing operations. For the years ended December 31, 2023, 2022 and 2021, the ten largest customers of the Company accounted for approximately 73%, 66% and 81%, respectively, of the Company’s operating revenues from continuing operations. The loss of one or more of these customers could have a material adverse effect on the Company’s results of operations and cash flows. For the years ended December 31, 2023, 2022 and 2021, approximately 79%, 72% and 88%, respectively, of the Company’s operating revenues and $3.6 million, $7.0 million and $15.4 million, respectively, of equity in earnings from 50% or less owned companies, net of tax, were derived from its continuing foreign operations. The Company’s offshore support vessels are highly mobile and regularly and routinely move between countries within a geographic region of the world. In addition, these vessels may be redeployed among the geographic regions, subject to flag restrictions, as changes in market conditions dictate. Because of this asset mobility, operating revenues and long-lived assets in any one country and capital expenditures for long-lived assets and gains or losses on asset dispositions and impairments in any one geographic region are not considered meaningful. 113 Direct vessel profit is the Company’s measure of segment profitability when applied to reportable segments. Direct vessel profit is defined as operating revenues less direct operating expenses excluding leased-in equipment expense. The Company utilizes direct vessel profit as its primary financial measure to analyze and compare the operating performance of its regions.
