Table of Contents/ PART I Item 1. Business. GENERAL DEVELOPMENT OF BUSINESS Oceaneering International, Inc. (“Oceaneering,” “we,” “us” or “our”) is a global technology company delivering engineered services and products and robotic solutions to the offshore energy, defense, aerospace and manufacturing industries. Oceaneering was organized as a Delaware corporation in 1969 out of the combination of three diving service companies founded in the early 1960s. Since our establishment, we have concentrated on the development and marketing of underwater services and products to meet customer needs requiring the use of advanced technology. The continued evolution of applying our advanced technologies has expanded our presence into numerous adjacent markets focused on autonomous robotics. We believe we are one of the world's largest underwater services contractors. The services and products we provide to the energy industry include remotely operated vehicles, survey and positioning services, specialty subsea hardware, engineering and project management, subsea intervention services, including manned diving and asset integrity and non-destructive testing services. Our foreign operations, principally in Africa, United Kingdom (“U.K.”), Norway, Brazil and Asia and Australia accounted for approximately 55% of our revenue, or $1.5 billion, for the year ended December 31, 2025. We operate in five business segments. Our segments are contained within two businesses—services and products provided primarily to the oil and gas industry, and to a lesser extent, the mobility solutions and offshore renewables industries, among others (“Energy”), and services and products provided to non-energy industries (“Aerospace and Defense Technologies”). Our four segments within the Energy business are Subsea Robotics, Manufactured Products, Offshore Projects Group and Integrity Management & Digital Solutions. We report our non-energy business, Aerospace and Defense Technologies, as one segment. Unallocated Expenses are expenses not associated with a specific business segment. These consist of expenses related to our incentive and deferred compensation plans, including restricted stock units, performance units and bonuses, as well as other general expenses, including corporate administrative expenses. We intend to continue our strategy of acquiring, as opportunities arise, additional assets or businesses, to improve our market position or expand into related service and product lines. Our most recent acquisition was in October 2024, when we acquired Global Design Innovation Ltd. (“GDi”), a U.K.-based provider of digital and software services, for approximately $33 million. This acquisition is a key step in Oceaneering’s strategy to advance its digital capabilities and broaden the solutions available to our global customers. We continue to focus on generating significant free cash flow and spending capital prudently to leverage our core competencies in new and existing markets. We will continue to develop and deliver technologies to help our customers produce hydrocarbons in a cleaner, safer and more cost-effective manner while increasing our investments into new markets including aerospace and defense solutions, digital asset management, energy transition and mobility solutions. Energy. The primary focus of our Energy business is to continue driving the positive momentum associated with the operational efficiency programs that leverage our asset base and capabilities for providing services and products for offshore energy operations and subsea completions. These efforts continue to benefit us during the current upstream spending cycle that is consistent with the ongoing global demand for energy. We are also focused on deploying our capabilities to grow our business in integrity management, survey services, mobile robotics, offshore wind installations, nuclear and other clean energy solutions. Subsea Robotics. Our Subsea Robotics segment consists of our work-class remotely operated vehicles (“ROVs”), survey services and ROV tooling businesses. We provide work-class ROVs, which are tethered submersible vehicles remotely operated from the surface, to customers in the offshore energy industry for drill support and vessel-based services, including subsea hardware installation, construction, pipeline inspection, survey and facilities inspection, maintenance and repair (“IMR”). We design, build, retrofit and upgrade our new and existing ROVs at in-house facilities, the largest of which is in Morgan City, Louisiana. In 2025, we retired sixteen of our conventional work-class ROV systems and replaced them with sixteen upgraded conventional work-class ROV systems. Our work-class ROV fleet size was 250 as of December 31, 2025, 2024 and 2023 and included eight Isurus work-class ROV systems (which are capable of operating in high-current conditions and are ideal for renewables projects and high-speed surveys) and our battery-operated Liberty electric ROV (“E-ROV”) system, which we developed to TM 2
Page 5
Table of Contents/ address customer objectives regarding cost and personnel efficiencies, along with safety and environmental considerations. The E-ROV system allows our customers to reduce carbon dioxide and other “greenhouse gas“ (“GHG”) emissions associated with offshore production operations. This system does not require a dedicated vessel to be on standby during ROV operations and reduces the need for ROV and other vessel-based personnel to be transported to and from marine vessels and offshore platforms, making the system more cost-efficient and safer for our customers. Additionally, we offer Freedom, a hybrid autonomous underwater vehicle (“AUV”) and ROV that can complete surveys, commissioning, inspections, maintenance, and repairs without the need for a pilot to monitor and control the entire operation. Freedom combines the data resolution and completeness of coverage in a single pass usually only obtainable using an ROV, but with the speed and efficiency of a traditional AUV. We intend to continue to expand our remote service offerings in this segment given the potentially significant savings both financially and in CO ₂ emissions available from Freedom, Liberty and Isurus systems. Our ROV tooling provides an operational interface between the ROV and subsea equipment. Our survey services business includes hydrographic survey and positioning services and autonomous underwater vehicles for geoscience. As part of our survey business, our C-Nav® satellite positioning services provide high-accuracy, global navigation satellite system (“GNSS”) corrections designed to support offshore navigation and marine operations with reliable and redundant positioning capability. Manufactured Products. Our Manufactured Products segment provides distribution systems, such as production control umbilicals and connection systems made up of specialty subsea hardware, along with clamp connectors and subsea and topside control valves. We also provide turnkey solutions that include project management, engineering design, fabrication, assembly and installation of autonomous mobile robotic technology to industrial, manufacturing, healthcare and warehousing markets. We provide various types of subsea umbilicals through our Umbilical Solutions division from facilities in the United States, Scotland and Brazil. Offshore operators use umbilicals to control subsea wellhead hydrocarbon flow rates, monitor downhole and wellhead conditions and perform chemical injection. Subsea umbilicals are also used to provide power and fluids to other subsea processing hardware, including pumps and gas separation equipment. Offshore Projects Group. Our Offshore Projects Group (“OPG”) segment provides a broad portfolio of integrated subsea project capabilities and solutions as follows: • subsea installation and intervention, including riserless light well intervention (“RLWI”) services, IMR services, principally in the United States (“U.S.”) Gulf and offshore Africa, utilizing owned and chartered vessels; • installation and workover control systems (“IWOCS”) and ROV workover control systems (“RWOCS”); • diving services; • decommissioning services; • project management and engineering; and • drill pipe riser services and systems and wellhead load relief solutions. Our OPG segment provides vessel-based services principally in the U.S. Gulf and offshore Africa, utilizing a fleet consisting of two owned and five chartered dynamically positioned deepwater vessels with integrated high-specification work-class ROVs onboard, and one owned survey vessel, other spot-chartered vessels and other assets. Our owned vessels are Jones Act- compliant. The dynamically positioned vessels are equipped with thrusters that allow them to maintain a constant position at a location without the use of anchors. They are used in the IMR of subsea facilities, pipeline or flowline tie-ins, pipeline crossings and installations. These vessels can also carry and install equipment or umbilicals required to bring subsea well completions into production (tie-back to production facilities). Integrity Management & Digital Solutions. Our Integrity Management & Digital Solutions (“IMDS”) segment provides asset integrity management, corrosion management, inspection and nondestructive testing services, principally to customers in the oil and gas, power generation and petrochemical industries. We perform these services on both onshore and offshore facilities, both topside and subsea. We also provide software, digital and connectivity solutions for the energy industry. Aerospace and Defense Technologies. Our ADTech segment provides services and products, including engineering and related manufacturing in defense and space exploration activities, principally to U.S. government agencies and their prime contractors. Many of the services and products utilized in ADTech are applied technologies TM 3

Energy exploration and development expenditures fluctuate from year to year. In particular, budgetary approval for drilling and production in deepwater, an area in which we have a high degree of focus, may be postponed or suspended during periods when exploration and production companies reduce their offshore capital spending. Over the last several years, one of our focus areas has been to increase our service and product offerings toward our energy customers' operating expenditures and the offshore renewables energy market. We market our Subsea Robotics, Manufactured Products, OPG and IMDS services and products to domestic, international and foreign national energy companies engaged in offshore exploration, development and production. We also provide services and products as a subcontractor to other oilfield service companies operating as prime contractors. In addition, we market our Manufactured Products mobile robotic solutions to domestic and international industrial, manufacturing, healthcare and warehousing industries. Customers for our energy services and products typically award contracts on a competitive-bid basis. These contracts can range from less than one year in duration to multi-year contracts. In connection with the services we perform in our Energy business, we generally seek contracts that compensate us on a dayrate basis. Under dayrate contracts, the contractor provides the ROV, vessel or equipment and the required personnel to operate the unit and compensation is based on a rate per day for each day the unit is used. The typical dayrate depends on market conditions, the nature of the operations to be performed, the duration of the work, the equipment and services to be provided, the geographical areas involved and other variables. Dayrate contracts may also contain an alternate, lower dayrate that applies when a unit is moving to a new site or when operations are interrupted or restricted by equipment breakdowns, adverse weather or water conditions or other conditions beyond the contractor's control. Contracts for our product sales are generally for a fixed price. Aerospace and Defense Technologies. We market our engineered products and services primarily to U.S. government agencies and their prime contractors in defense and space exploration activities, as well as commercial space companies. Major Customers. Our top five customers in 2025, 2024 and 2023 accounted for 31%, 31% and 36%, respectively, of our consolidated revenue. In 2025, 2024 and 2023, four of our top five customers were oil and gas exploration and production companies served by our Energy business segments, with the other one being the U.S. Government, which is served primarily by our ADTech segment. For the year ended December 31, 2025, revenue from one customer, the U.S. Government, accounted for 12% of our total consolidated annual revenue, and no other customer accounted for more than 10% of our total consolidated revenue. For the year ended December 31, 2024, no individual customer accounted for more than 10% of our consolidated revenue. For the year ended December 31, 2023, revenue from one customer, the U.S. Government, accounted for 10% of our total consolidated annual revenue, and no other customer accounted for more than 10% of our total consolidated revenue. Although we do not depend on any one customer, the loss of one of our significant customers could, at least on a short-term basis, have an adverse effect on our results of operations and cash flows. RAW MATERIALS We purchase various raw materials for use in manufacturing our products and delivering our services. The key raw materials we use include steel in various forms, polymers, copper wire, electronic components and plastics. Most of the raw materials that are critical to our business are generally readily available from multiple sources but may be subject to price volatility. In addition, global market conditions can trigger constraints in the supply of certain raw 6
Page 9
Table of Contents/ materials, and our procurement personnel are always seeking ways to ensure the availability and manage the cost of raw materials. In addition to raw materials, we also use the products and services of a number of other providers, such as forge companies, casting foundries, metal fabricators, machine shops and logistics providers, in order to produce and deliver products to our customers. Most of these materials and services are generally available from multiple sources. COMPETITION Our businesses operate in highly competitive industry segments. Energy. We are one of several companies that provide underwater services and specialty subsea hardware on a worldwide basis. We compete for contracts with companies that have worldwide operations, as well as numerous others operating locally in various areas. We believe that our ability to safely provide a wide range of underwater services and products on a worldwide basis enables us to compete effectively in multiple phases of the offshore oilfield life cycle. In some cases involving projects that require less sophisticated equipment, small companies have been able to bid for contracts at prices uneconomical to us. Additionally, in some jurisdictions we are subject to foreign governmental regulations favoring or requiring the awarding of contracts to local contractors or requiring foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. These regulations may adversely affect our ability to compete. Subsea Robotics. We believe we are the world's largest owner and operator of work-class ROVs employed in energy-related operations. As of December 31, 2025, we owned 250 work-class ROVs. We compete with several major companies on a worldwide basis and with numerous others operating locally in various areas. Competition for ROV services, including ROV tooling, historically has been based on equipment availability, location of or ability to deploy the equipment, quality of service and price. The relative importance of these factors can vary over time based on market conditions. The ability to develop improved equipment and techniques and to attract, train and retain skilled personnel is also an important competitive factor in our markets. Our survey and positioning services operate in a competitive environment, as one of several companies that provide these services. Additionally, in recent years, we have been targeting increasing our presence in international markets through the use of simultaneous operations that have enhanced our ability to conduct remote operations. Manufactured Products. With our manufactured products business, we are one of several companies that compete on a worldwide basis for the provision of steel tube and thermoplastic control umbilicals. Compared to current and forecasted market demand, coupled with competitors reducing supply capacity, we have seen improvements in the umbilical manufacturing and energy markets. We believe the reduction in capacity by some of our competitors over the last few years, coupled with an increase in demand, should help with balancing a historically over-supplied market. Within our mobility solutions business, there are many niche competitors offering specialized services and products, both on a regional and a global basis. Offshore Projects Group. We perform subsea intervention and hardware installation services, principally in the U.S. Gulf and offshore Africa, from multiservice deepwater vessels. We are one of many companies that offer these services. In general, our competitors can move their vessels to where we operate from other locations with relative ease. However, some of our competitors’ vessels are not Jones Act-compliant, which requires that vessels operating in the U.S. Gulf be built and registered in the United States and 75% U.S. owned in order to transport merchandise between points in the United States. Within our service and rental businesses, there are many competitors offering specialized services and products both on a regional and a global basis. Integrity Management & Digital Solutions. The worldwide asset integrity and inspection markets consist of a wide range of inspection and certification requirements in many industries. We currently compete in only selected portions of this market. We are expanding our integrity management services into adjacent markets and are developing our digitization services. We believe that our broad geographic sales and operational coverage, long history of operations, technical and safety reputation, application of various inspection technologies and accreditation to international quality standards enable us to compete effectively in our selected asset integrity and inspection services market segments. Aerospace and Defense Technologies. Engineering services is a very broad market with a large number of competitors. We compete in specialized areas in which we can combine our extensive knowledge of operating in 7
Page 10
Table of Contents/ harsh environments, program management experience, mechanical engineering expertise and the capability to continue the development of conceptual project designs into the manufacture of custom equipment for customers. SEASONALITY AND BACKLOG We generate a material amount of our consolidated revenue from contracts for services in the U.S. Gulf within our OPG segment. This segment typically experiences higher activity levels during the second and third quarters, as compared to the rest of the year. Notably, the fourth quarter of 2024 and the first quarter of 2025 represented a positive exception to this pattern. Revenue in our Subsea Robotics segment is subject to seasonal variations in demand, with our first quarter generally being the low quarter of the year. The level of our Subsea Robotics seasonality depends on the number of ROVs we have engaged in vessel-based subsea infrastructure IMR and installation, which is more seasonal than drill support. Revenue in each of our Manufactured Products, IMDS and ADTech segments generally has not been seasonal. The amounts for backlog orders we believed to be firm as of 2025 and 2024 were as follows (in millions): As of December 31, 2025 As of December 31, 2024 Total 1 yr 1+ yr Total 1 yr 1+ yr Energy Subsea Robotics $ 1,041 $ 550 $ 491 $ 876 $ 521 $ 355 Manufactured Products 511 411 100 604 439 165 Offshore Projects Group 375 212 163 416 261 155 Integrity Management & Digital Solutions 517 232 285 291 171 120 Total Energy 2,444 1,405 1,039 2,187 1,392 795 Aerospace and Defense Technologies 259 239 20 252 210 42 Total $ 2,703 $ 1,644 $ 1,059 $ 2,439 $ 1,602 $ 837 (1) Represents amounts that are expected to be performed within one year. (2) Represents amounts that are not expected to be performed within one year. If any of our contracts with firm orders were to be terminated, our backlog would be reduced by the expected value of the unfilled orders of such contracts. As of December 31, 2025 and 2024, not included in the table above, we had unfunded (firm orders that have not yet been paid for by our customers) contracted backlog of approximately $658 million and $279 million, respectively, in our ADTech segment. Unexercised contract options and indefinite delivery/indefinite quantity (“IDIQ”) contracts are not included in backlog until the time the option or IDIQ task order is exercised or awarded. PATENTS AND LICENSES We currently hold numerous U.S. and foreign patents and pending patent applications. We have acquired patents and licenses and granted licenses to others when we have considered it advantageous for us to do so. Although in the aggregate our patents and licenses are important to us, we do not regard any single patent or license or group of related patents or licenses as critical or essential to our business as a whole. In general, we depend on our technological capabilities and the application of know-how rather than patents and licenses in the conduct of our operations. REGULATION Our operations are affected from time to time and in varying degrees by foreign and domestic political developments and foreign, federal and local laws and regulations, including those relating to: • operating from and around offshore drilling, production and marine facilities; • national preference for local equipment and personnel; • marine vessel safety; • protection of the environment, including pollution, GHG emissions and climate change; • workplace health and safety; (1) (2) (1) (2) 8
Page 11
Table of Contents/ • data privacy; • taxation (including tariffs and retaliatory tariffs); • license requirements for importation and exportation of our equipment and technology; and • currency conversion and repatriation. In addition, our Energy business primarily depends on the demand for our services and products from the oil and gas industry and, therefore, is affected by changing taxes, price controls and other laws and regulations relating to the oil and gas industry generally. The adoption of laws and regulations curtailing offshore exploration and development drilling for oil and gas for economic and other policy reasons (such as addressing concerns about climate change or banning offshore exploration and production in certain geographic areas) would adversely affect our operations by limiting demand for our services. We cannot determine the extent to which new legislation, new regulations or changes in existing laws or regulations may affect our future operations. Our operations and properties are subject to a wide variety of increasingly complex and stringent foreign, federal, state and local environmental laws and regulations, including those governing discharges into the air and water, the handling and disposal of solid and hazardous wastes, the remediation of soil and groundwater contaminated by hazardous substances and the health and safety of employees. Sanctions for noncompliance may include revocation of permits, corrective action orders, administrative or civil penalties and criminal prosecution. Some environmental laws provide for strict, joint and several liability for remediation of spills and other releases of hazardous substances, as well as damage to natural resources. In addition, companies may be subject to claims alleging personal injury or property damage as a result of alleged exposure to hazardous substances. These laws and regulations may also expose us to liability for the conduct of or conditions caused by others, or for our acts that were in compliance with all applicable laws at the time such acts were performed. Environmental laws and regulations that apply to our operations include the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act (each, as amended) and similar laws that provide for responses to, and liability for, releases of hazardous substances into the environment. Environmental laws and regulations also include similar foreign, state or local counterparts to the above- mentioned federal laws, which regulate air emissions, water discharges, hazardous substances and waste, and require public disclosure related to the use of various hazardous substances. Our operations are also governed by laws and regulations relating to workplace safety and worker health, primarily, in the United States, the Occupational Safety and Health Act and regulations promulgated thereunder. Compliance with federal, state and local provisions regulating the discharge of materials into the environment or relating to the protection of the environment has not had a material impact on our capital expenditures, earnings or competitive position. We cannot predict all of the environmental requirements or circumstances that will exist in the future but anticipate that environmental control and protection standards will become increasingly stringent and costly. Based on our experience to date, we do not currently anticipate any material adverse effect on our business or consolidated financial position, results of operations or cash flows as a result of future compliance with existing environmental laws and regulations. However, future events, such as changes in existing laws and regulations or their interpretation, more vigorous enforcement policies of regulatory agencies, or stricter or different interpretations of existing laws and regulations, may require additional expenditures by us, which may be material. Accordingly, there can be no assurance that we will not incur significant environmental compliance costs in the future. Our quality management systems are, at a minimum, registered as being in conformance with ISO 9001:2015, with several locations also conforming with ISO 29001:2020 and cover: • our Subsea Robotics operations in the U.S. Gulf, the U.K., Norway, Angola, Ghana, Brazil, Canada, India, the United Arab Emirates, Australia, Azerbaijan, Thailand, Indonesia and Malaysia; • our Manufactured Products operations in Brazil, Canada, the U.S., the U.K., Norway, Malaysia, the Netherlands, Germany and Angola; • our Offshore Projects Group operations in the U.S. Gulf, the U.K., Norway, Angola, Ghana, Brazil, Canada, India, the United Arab Emirates, Australia, Azerbaijan, Indonesia, Singapore, Thailand and Malaysia; • our Integrity Management & Digital Solutions operations in the U.S. Gulf, the U.K., Norway, Brazil, Angola, the United Arab Emirates, Oman, Qatar, Australia, Malaysia, Indonesia and Azerbaijan; and • the Oceaneering Space Systems, Oceaneering Technologies and Marine Services divisions of our Aerospace and Defense Technologies segment in the U.S. 9

Table of Contents/ ISO 9001 is an internationally recognized system for quality management established by the International Standards Organization, and the 2015 edition emphasizes customer satisfaction, risk assessment and continual improvement. ISO 29001 is supplemental to ISO 9001 and defines requirements for product and service supply organizations to the petroleum, petrochemical and natural gas industries with increased focus on supply chain risks, operational efficiency, safety, and quality. HUMAN CAPITAL RESOURCES Human Capital Programs and Metrics. We believe our future success largely depends on our continued ability to attract and retain highly skilled employees. Our attraction and retention efforts include: • Business Ethics. As described more fully below, we foster a culture that encourages Oceaneering employees (“Oceaneers”) to act with integrity and insist upon business ethics. • Compensation and Benefits. We aim to offer competitive compensation packages, including benefit packages tailored to local markets of operation. • Career Development. We value continued learning and growth for all Oceaneers, regardless of their location, career path or background. In our global business, we develop talent and offer career advancement within local communities while offering exciting opportunities to deepen international business and cultural experiences for Oceaneers with such aspirations. We offer accelerated career paths for technicians into senior and supervisory roles as well as leadership development for personnel on professional career tracks. We regularly review our leadership bench strength and demonstrate a strong history of internal promotion. • Health, Safety, Security & Environment. We take a proactive, preventative, and people-first approach to health, safety, security and environmental (“HSSE”) risks in our business. We start by measuring leading indicators that provide opportunities to avoid HSSE events before they happen, and we keep HSSE at the forefront of our decisions. We expect full commitment to HSSE from all Oceaneers and from all of our business partners. • Diversity. Given our global footprint and the breadth of skills, qualifications, and perspectives required to achieve our business goals, we endeavor to attract, promote, and retain the best and brightest employees from all populations. Additionally, we value a culture where employees can be authentic at work, live their values, and grow and advance their careers. Our local, regional, and global employee resource groups are open to all Oceaneers and offer opportunities for networking, community-building, and knowledge enhancement. • Community Involvement. Oceaneers value addressing the needs of the communities in which they live and work. We support local, regional and global initiatives to address community needs, and we offer two paid volunteer days annually to all employees to enable them to participate in community outreach activities throughout the year. • Continual Improvement of Employee Experience. We believe that the employee value proposition can vary and evolve from place to place and from time to time. With that in mind and with a commitment to continual improvement of the employee experience, we conduct periodic employee engagement surveys to gauge engagement of Oceaneers. As of December 31, 2025, we had approximately 11,100 employees, of whom approximately 35% were employed in the United States and approximately 65% were employed outside of the United States. Our workforce varies seasonally and typically peaks during the second and third quarters of each year. In 2025, we worked in approximately 48 countries across six continents and employed people representing over 117 different nationalities. Business Ethics Our Code of Conduct applies to all of our directors, officers and employees. Additionally, our joint venture partners, consultants, agents, subcontractors and other business partners must follow applicable law and ethical business practices consistent with our Code of Conduct when working on our behalf. The Code of Conduct is approved by the Board of Directors and is regularly reviewed by the Audit Committee. Waivers of the Code of Conduct are to be granted only by our Board of Directors. We intend to satisfy the requirement under Item 5.05 of Form 8-K to disclose any amendments to our Code of Conduct and any waiver from a provision of our Code of Conduct by posting such information on our website at www.oceaneering.com under "Investors—Governance." 10

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS We are including the following discussion to inform our existing and potential security holders generally of some of the risks and uncertainties that can affect our company and to take advantage of the “safe harbor” protection for forward-looking statements that applicable federal securities law affords. From time to time, our management or persons acting on our behalf make forward-looking statements to inform existing and potential security holders about our company. These statements may include projections and estimates concerning the timing and success of specific projects and our future orders, revenue, income and capital spending. Forward-looking statements are generally accompanied by words such as “estimate,” “plan,” “project,” “predict,” “believe,” “expect,” “anticipate,” “plan,” “forecast,” “budget,” “goal,” “may,” “should,” or other words that convey the uncertainty of future events or outcomes. In addition, sometimes we will specifically describe a statement as being a forward-looking statement and refer to this cautionary statement. In addition, various statements this report contains, including those that express a belief, expectation or intention, or that express a future goal or commitment, are forward-looking statements. Those forward-looking statements appear in Part I of this report in Item 1—“Business,” Item 2—“Properties” and Item 3—“Legal Proceedings” and in Part II of this report in Item 7 —“Management's Discussion and Analysis of Financial Condition and Results of Operations,” Item 7A—“Quantitative and Qualitative Disclosures About Market Risk” and in the Notes to Consolidated Financial Statements incorporated into Item 8 and elsewhere in this report. These forward-looking statements speak only as of the date of this report, we disclaim any obligation to update these statements, and we caution you not to rely unduly on them. We have based these forward-looking statements on our current expectations and assumptions about future events. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control. These risks, contingencies and uncertainties relate to, among other matters, the following: • factors affecting the level of activity in the energy industry, including worldwide demand for and prices of oil and natural gas, oil and natural gas production growth and the supply and demand of offshore drilling rigs; • actions by members of the Organization of Petroleum Exporting Countries (“OPEC”), and other oil exporting countries; • decisions about offshore developments to be made by oil and gas exploration, development and production companies; • decisions about offshore developments to be made by offshore renewables companies; • the use of subsea completions and our ability to capture a share of the associated market; • factors affecting the level of activity in our government businesses, including decisions on spending and funding by the U.S. Government; • factors affecting our ability to achieve our growth expectations for our mobile robotics technology products; • general economic and business conditions and industry trends, including the ongoing transition to alternative sources of energy to reduce worldwide emissions of carbon dioxide and other “greenhouse gases,” the effects of inflation and future monetary policies and actions of the Federal Reserve; • the strength of the industry segments in which we are involved; • cancellations of contracts, change orders and other contractual modifications and the resulting adjustments to our backlog; • collections from our customers; • the availability and increased costs of chartered vessels; • our future financial performance, including as a result of the availability, terms and deployment of capital; • the consequences of significant changes in currency exchange rates; 11
Page 14
Table of Contents/ • the volatility and uncertainties of credit markets; • our ability to comply with covenants in our credit agreements and other debt instruments and the availability, terms and deployment of capital; • changes in tax laws, regulations and interpretation by taxing authorities; • changes in, or our ability to comply with, other laws and governmental regulations, including those relating to the environment (including pollution and climate change); • the continued availability of qualified personnel and our ability to attract and retain those qualified personnel; • our ability to obtain raw materials and parts on a timely basis and, in some cases, from limited sources; • increases in material costs on long-term projects at prices higher than originally forecast; • operating risks normally incident to offshore exploration, development and production operations; • hurricanes and other adverse weather and sea conditions; • cost and time associated with drydocking of our vessels; • the highly competitive nature of our businesses; • adverse outcomes from legal or regulatory proceedings; • the risks associated with integrating businesses we acquire; • the risks associated with the use of complex information technology systems, including cybersecurity risks and the risks associated with failures to protect data privacy in accordance with applicable legal requirements and contractual provisions binding upon us; • rapid technological changes; and • social, political, military and economic situations in countries where we do business and the possibilities of civil disturbances, war, other armed conflicts or terrorist attacks. We believe the items we have outlined above are important factors that could cause our actual results to differ materially from those expressed in a forward-looking statement made in this report or elsewhere by us or on our behalf. We have discussed most of these factors in more detail elsewhere in this report. These factors are not necessarily all the factors that could affect us. Unpredictable or unanticipated factors we have not discussed in this report could also have material adverse effects on actual results of matters that are the subject of our forward-looking statements. We do not intend to update our description of important factors each time a potential important factor arises. We advise our security holders that they should (1) be aware that important factors we do not refer to above could affect the accuracy of our forward-looking statements and (2) use caution and common sense when considering our forward-looking statements.

Table of Contents/ Item 1A. Risk Factors. We are subject to various risks and uncertainties in the course of our business. The following summarizes the risks and uncertainties that we consider to be material and that may materially and adversely affect our business, financial condition, results of operations or cash flows and the market value of our securities. Investors in our company should consider these matters, in addition to the other information we have provided in this report and the documents we incorporate by reference. Business and Operational Risks We derive most of our revenue from companies in the offshore oil and gas industry, a historically cyclical industry with levels of activity that are significantly affected by the levels and volatility of oil and gas prices. We derive most of our revenue from customers in the offshore oil and gas exploration, development and production industry. The offshore oil and gas industry is a historically cyclical industry characterized by significant changes in the levels of exploration and development activities. Oil and gas prices, and market expectations of potential changes in those prices, significantly affect the levels of those activities. Worldwide political, economic and military events have contributed to oil and gas price volatility and are likely to continue to do so in the future. In addition, there is ongoing uncertainty regarding the long- term outlook for offshore drilling in the United States, including the U.S. Gulf, as a result of ongoing litigation in U.S. federal courts regarding the ability of the President to reverse a previous President’s withdrawal of acreage from future oil and gas leasing under the Outer Continental Shelf Lands Act, as amended (the “OCSLA”). As a result, the impact of Executive Order No. 14148, which attempted to reverse the Biden Administration’s withdrawal of acreage from oil and gas leasing pursuant to the OCSLA, remains to be seen. Any prolonged reduction in the overall level of offshore oil and gas exploration and development activities, whether resulting from changes in oil and gas prices, limitations on access to capital for such activities, governmental actions or regulatory developments or otherwise, could materially and adversely affect our financial condition and results of operations in our operating segments within our Energy business. Some factors that have affected and are likely to continue affecting oil and gas prices and the level of demand for our services and products include the following: • worldwide demand for energy; • general economic and business conditions and industry trends; • the ability of OPEC to set and maintain production levels; • the level of production by non-OPEC countries; • the ability of oil and gas companies to generate funds for capital expenditures; • the ongoing ability to access external financing from financial institutions or the capital markets; • the cost of exploring for, developing and producing oil and gas as compared to alternative energy sources; • domestic and foreign tax policy; • laws and governmental regulations that restrict exploration and development of oil and gas in various offshore jurisdictions; • technological changes that could lead to competition from new market entrances; • technological advances that impact the demand for energy, as well as the production of oil and gas; • the political environment of oil-producing regions; • the changing environmental and social landscape; • the price and availability of alternative energy; • war, sabotage, terrorism and civil unrest, including conflicts throughout the world where we and our customers operate; and • extreme weather conditions, natural disasters, public health crises and pandemics or epidemics, such as COVID-19 and variants thereof. Our operations could be adversely impacted by increased transition to renewable or other alternative energy sources as a result of climate change and climate-related business trends. Increasing transition to renewable or other alternative energy sources has begun in recent years due to the scientific and regulatory concern regarding global warming and other climatic changes. Although it is not possible at this time to predict the timing and effect of climate-related business trends, any such developments, including the declining 16
Page 19
Table of Contents/ cost of renewable energy generation technologies (and the increased demand thereof), continued government subsidies, and the continuing electrification of various technologies that previously used hydrocarbons, could impact the long-term demand for oil and natural gas and, ultimately, the demand for the services and products of our Energy business. Climate-related business trends could result in, among other things, decreased demand for goods or services that produce significant greenhouse gas emissions, such as our fleet of vessels, increased demand for goods that result in lower emissions than competing products and increased competition to develop innovative new products that result in lower emissions. As we strive to develop innovative new product offerings, we aim to address a myriad of challenges facing our customers and the industries that we serve, including, among many others, energy efficiency, labor shortages, safety and climate change. To meet these challenges, we strive to innovate products and services that, in addition to lowering greenhouse gas emissions for our customers, offer higher energy efficiency, fewer personnel requirements due to more automation and superior safety characteristics. While this creates opportunities for our business, we face the risk that we will be unable to execute on such innovation in a timely manner, or at all, which may materially and adversely affect our business, financial condition, results of operations or cash flows if our customers turn to other suppliers for these products. If we are unable to meet increased customer expectations around the energy efficiency and carbon emissions of our new products, our business or our reputation could be negatively impacted. Further, increased demand for generation and transmission of energy from alternative energy sources could result in a decreased demand for goods or services that complement the hydrocarbon industry generally, even if those goods and services themselves do not produce significant greenhouse gas emissions, such as our remotely operated vehicles. Our business could be negatively impacted if we are unable to successfully market our products and services to customers who produce energy from alternative energy sources. Beyond financial impacts, climate change poses potential physical risks. Scientific studies forecast that these risks include increases in sea levels, stresses on water supply, rising average temperatures and other changes in weather conditions, such as increases in precipitation and extreme weather events, such as floods, heat waves, hurricanes and other tropical storms and cyclones. The projected physical effects of climate change have the potential to directly affect the operations we conduct for customers and result in increased costs related to our operations. However, because the nature and timing of changes in extreme weather events (such as increased frequency, duration, and severity) are uncertain, it is not possible for us to estimate reliably the future financial risk to our operations caused by these potential physical risks. Our international operations involve additional risks not associated with domestic operations. A significant portion of our revenue is attributable to operations in foreign countries. These activities accounted for approximately 55% of our consolidated revenue in 2025. Risks associated with our operations in foreign areas include risks of: • regional and global economic downturns; • expropriation, confiscation or nationalization of assets; • renegotiation or nullification of existing contracts; • foreign exchange restrictions; • foreign currency fluctuations, particularly in countries highly dependent on oil revenue; • foreign taxation, including the application and interpretation of tax laws; • the inability to repatriate earnings or capital; • changing political conditions; • changing foreign trade policies and tariffs and potential impacts of legal challenges thereto; • changing foreign and domestic monetary policies; • public health crises, such as COVID-19, Severe Acute Respiratory Syndrome, severe influenza and other highly communicable viruses or diseases, that could limit our access to customers', vendors' or our facilities or offices, impose travel restrictions on our personnel or otherwise adversely affect our operations or demand for our services; and • social, political, military and economic situations in foreign areas where we do business and the possibilities of civil disturbances, war, other armed conflict, terrorist attacks or acts of piracy. 17

Table of Contents/ Changes in U.S. foreign trade policies could lead to the imposition of additional trade barriers and tariffs on us. We cannot predict what changes to trade policy will be made by the current or a future presidential administration or Congress, including whether existing tariff policies will be maintained or modified (or if legal challenges to such policies will prevail), or whether the entry into new bilateral or multilateral trade agreements will occur, nor can we predict the effects that any such changes would have on our business. Changes in U.S. trade policy have resulted and could again result in reactions from U.S. trading partners, including adopting responsive trade policies making it more difficult or costly for us to export our products to countries where we currently sell products. Such changes in U.S. trade policy or in laws and policies governing foreign trade, and any resulting negative sentiments towards the United States as a result of such changes, could materially and adversely affect our business, operations, financial condition and results of operations. Additionally, in some jurisdictions we are subject to foreign governmental regulations favoring or requiring the awarding of contracts to local contractors or requiring foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. These regulations may adversely affect our ability to compete. Our exposure to the risks we described above varies from country to country. There is a risk that a continuation or worsening of these conditions could materially and adversely impact our future business, operations, financial condition and results of operations. Our backlog is subject to unexpected adjustments and cancellations and is, therefore, an uncertain indicator of our future revenue and earnings. There can be no assurance that the revenue included in our backlog will be realized or, if realized, will result in profits. Because of project cancellations or potential changes in the scope or schedule of our customers' projects, we cannot predict with certainty when or if backlog will be realized. Material delays, suspensions, cancellations or payment defaults could materially affect our financial condition, results of operations and cash flows. We may be at risk of delays, suspensions and cancellations in the current market environment. Reductions in our backlog due to cancellation by a customer or for other reasons would adversely affect, potentially to a material extent, the revenue and earnings we actually receive from contracts included in our backlog. Many of our ROV contracts have 30-day notice termination clauses. Some of the contracts in our backlog provide for cancellation fees in the event customers cancel projects. These cancellation fees usually provide for reimbursement of our out-of-pocket costs, revenue for work performed prior to cancellation and a varying percentage of the profits we would have realized had the contract been completed. However, under limited circumstances, such as certain bankruptcy events, no cancellation fee would be owed to us. Further, even if a cancellation fee is owed to us, a customer may be unable or may refuse to pay the cancellation fee. We typically have no contractual right upon cancellation to the total contract revenue as reflected in our backlog. If we experience significant project terminations, suspensions or scope adjustments to contracts reflected in our backlog, our financial condition, results of operations and cash flows may be adversely impacted. Our offshore oilfield operations involve a variety of operating hazards and risks that could cause losses. Our offshore oilfield operations are subject to the hazards inherent in the offshore oilfield business. These include blowouts, explosions, fires, collisions, capsizings and severe weather conditions. These hazards could result in personal injury and loss of life, severe damage to or destruction of property and equipment, pollution or environmental damage and suspension of operations. We may incur substantial liabilities or losses as a result of these hazards. While we maintain insurance protection against some of these risks and seek to obtain indemnity agreements from our customers requiring the customers to hold us harmless from some of these risks, our insurance and contractual indemnity protection may not be sufficient or effective to protect us under all circumstances or against all risks. The occurrence of a significant event not fully insured or indemnified against or the failure of a customer to meet its indemnification obligations to us could materially and adversely affect our results of operations and financial condition. We may be adversely affected by changes in levels of U.S. government spending or acquisition priorities, as well as significant delays in U.S. government appropriations. Our ADTech segment provides services and products, including engineering and related manufacturing in defense and space exploration activities, principally to U.S. government agencies and their prime contractors. Levels of U.S. defense and space exploration spending are difficult to predict and may be impacted by numerous factors such as 18
Page 21
Table of Contents/ the evolving nature of the national security threat environment, U.S. national security strategy, U.S. foreign policy, the domestic political environment, macroeconomic conditions and the ability of the U.S. government to enact relevant legislation such as authorization and appropriations bills. The government may also constrain discretionary spending by instituting enforceable spending caps. A reduction in overall U.S. spending, on an absolute or inflation-adjusted basis, because of shifting priorities, budget compromises or otherwise could adversely affect our business. Additionally, budget uncertainty, extended or repeated U.S. Government shutdowns, the use of continuing resolutions or the federal debt ceiling could adversely affect our industry and both the timing and quantum of funding for our programs or for the prime contractors for which we provide services. Legal and Regulatory Risks Legislative and regulatory responses to climate change and the ongoing “energy transition” could result in increased operating costs and capital expenditures and changes in demand for the services and products of our Energy business. The legislative and regulatory responses to climate change and its effects have the potential to negatively affect our business in many ways, including increasing the costs to provide the services and products of our Energy business, reducing the demand for and consumption of certain of those services and products, and the economic health of the regions in which we operate, all of which can create financial risks. Legislation to regulate greenhouse gas emissions has, from time to time, been introduced in the U.S. Congress and such legislation may be proposed or adopted in the future. It is not possible at this time to predict the timing and effect of climate change or to predict whether new greenhouse gas legislation, regulations or other measures will be adopted. However, more aggressive efforts by governments and non-governmental organizations to reduce greenhouse gas emissions may occur and any such future laws and regulations could result in increased compliance costs or additional operating restrictions applicable to our Energy business customers and/or us. Our business could also be impacted by governmental initiatives to incentivize the conservation of energy or the use of alternative energy sources. These initiatives to reduce energy consumption or incentivize a shift away from fossil fuels could reduce demand for hydrocarbons, thereby reducing demand for the goods and services of our Energy business, and adversely impact our business, financial condition, results of operations and cash flows. The adoption of additional climate change laws or regulations in the future could result in increased costs for our Energy business customers and us to (1) operate and maintain operating facilities, (2) install new emission controls or abatement technologies (such as carbon capture and storage (“CCS”) technologies) in operating facilities and (3) administer and manage greenhouse gas emissions programs. If we are unable to recover or pass through a significant level of our costs related to complying with climate change regulatory requirements imposed on us, they could have a material adverse effect on our results of operations and financial condition. Further, such legislation or regulation could prevent customer projects from going forward, thereby potentially reducing the need for our products and services. In addition, to the extent insurance carriers view climate change and the greenhouse gas emissions of our Energy business customer base as a financial risk, this could negatively impact our cost of insurance. In addition, climate change legislation and regulation may subject us to increased competition to develop innovative new products that result in lower emissions. Please refer to the risk factor entitled “Our operations could be adversely impacted by increased transition to renewable or other alternative energy sources as a result of climate change and climate-related business trends” for a discussion of the impact of other climate-related consequences on our business, financial condition, results of operations and cash flows. Concerns and negative public perception regarding us, our sustainability goals and our industry could adversely affect our business operations, which could result in reduced revenue and increased costs. Businesses across all industries are facing increasing scrutiny from investors, governmental authorities, regulatory agencies and the public related to their practices and disclosures related to climate change, sustainability, diversity and inclusion initiatives and heightened governance standards. Failure, or a perceived failure, to adequately respond to or meet evolving expectations, concerns and standards may cause us to suffer reputational damage and materially and adversely affect our business or financial condition, or the trading price of our securities. We may also communicate certain climate-related initiatives, commitments and goals in our SEC filings or in other disclosures, which subjects us to additional risks, including the risk of being accused of greenwashing. Alternatively, we may be accused of “greenhushing” for the failure to communicate certain climate-related initiatives, commitments and goals. 19
Page 22
Table of Contents/ Furthermore, negative public perception regarding us or the energy industry resulting from, among other things, concerns raised by advocacy groups about oil spills, greenhouse gas emissions, climate change and explosions of or leaks from pipelines carrying crude oil, refined petroleum products or natural gas, may lead to increased regulatory scrutiny, which may, in turn, lead to new safety and environmental laws, regulations, guidelines and enforcement interpretations. These actions may cause operational delays or restrictions, increased operating costs or capital expenditures, additional regulatory burdens and increased risk of litigation for us and our energy industry customers. Furthermore, governmental authorities exercise considerable discretion in the timing and scope of permit issuance required for the operations conducted by or for our energy industry customers and, in many cases, the public may engage in the permitting process. Negative public perception could cause such permits to be withheld, delayed, or burdened by requirements that restrict our ability to profitably conduct business for our energy industry customers. Ultimately, these risks could result in reduced demand for the services and products of our Energy business, which would adversely impact our revenues, and increased costs that may adversely affect our profitability and cash flows. Employee, agent or partner misconduct or our overall failure to comply with laws or regulations could weaken our ability to win contracts, which could result in reduced revenue and profits. Misconduct, fraud, non-compliance with applicable laws and regulations, or other improper activities by one or more of our employees, agents or partners could have a significant negative impact on our business and reputation. Such misconduct could include the failure to comply with the U.S. Foreign Corrupt Practices Act ("FCPA"), which prohibits companies and their intermediaries from making improper payments to non-U.S. officials, as well as the failure to comply with government procurement regulations, regulations on lobbying or similar activities, regulations pertaining to the internal controls over financial reporting and various other applicable laws or regulations, including the U.K. Bribery Act. We operate in some countries that international corruption monitoring groups have identified as having high levels of corruption. Our activities create the risk of unauthorized payments or offers of payments by one of our employees or agents that could be in violation of the FCPA or other applicable anti-corruption laws. The precautions we take to prevent and detect misconduct, fraud or non- compliance with applicable laws and regulations may not be effective, and we could face unknown risks or losses. In December 2024, the Chinese government placed restrictions on and sanctioned our parent company and certain executives in response to recent U.S. announcements of military sales and aid to Taiwan and in response to the recent approval of the U.S. government’s annual defense spending. Furthermore, in September 2025, the Chinese government placed us on its “Unreliable Entity List” and, as a result, we are generally prohibited from engaging in import or export activities related to China or making new investments in the country. We will continue to follow U.S. Government guidance as it relates to sales to Taiwan and do not currently expect a material impact to our business from these actions. Our failure to comply with applicable laws or regulations or acts of misconduct could subject us to fines, penalties or other sanctions, which could have a material adverse effect on our business and our consolidated financial condition, results of operations and cash flows. Laws and governmental regulations may add to our costs or adversely affect our operations. Our business is affected by changes in public policy and by federal, state, local and foreign laws and regulations, including those relating specifically to the offshore oil and gas industry. Offshore oil and gas exploration and production operations are affected by tax, environmental, safety and other laws, by changes in those laws, application or interpretation of existing laws, and changes in related administrative regulations. It is possible that such new laws and regulations, or changes to the application or interpretation of existing laws and regulations, may significantly increase our operating costs and those of our customers, or otherwise directly or indirectly affect our operations. Environmental laws and regulations can increase our costs, and our failure to comply with those laws and regulations can expose us to significant liabilities. Risks of substantial costs and liabilities related to environmental compliance issues are inherent in our operations. Our operations are subject to extensive federal, state, local and foreign laws and regulations relating to the generation, storage, handling, emission, transportation and discharge of materials into the environment. Permits are required for the operation of various facilities, and those permits are subject to revocation, modification and renewal. Governmental authorities have the power to enforce compliance with their regulations, and violations are subject to fines, injunctions or both. In some cases, those governmental requirements can impose liability for the entire cost of cleanup on any responsible party without regard to negligence or fault and impose liability on us for the conduct of or conditions others have caused, or for our acts that complied with all applicable requirements when we performed them. It is possible that other developments, such as stricter environmental laws and regulations, and claims for 20
Page 23
Table of Contents/ damages to property or persons resulting from our operations, would result in substantial costs and liabilities. Our insurance policies and the contractual indemnity protection we seek to obtain from our customers may not be sufficient or effective to protect us under all circumstances or against all risks involving compliance with environmental laws and regulations. We are currently subject to disputes, legal and regulatory claims, investigations and proceedings, some of which could be material. We are currently subject to disputes, legal and regulatory claims, investigations and proceedings and could become subject to additional disputes, claims, investigations and proceedings in the future, some of which could be material. These proceedings may be brought by the government or private parties and may arise out of a number of matters, including contract disputes, environmental claims, property disputes, antitrust claims and personal injury claims. We are currently in a contract dispute with a customer. Even if we are ultimately successful, defense of these claims can be costly and time-consuming and may divert management's attention and resources. The outcome of any pending or future claims, investigations or proceedings is inherently unpredictable, but such outcomes could have a material adverse effect on our business and our consolidated financial condition, results of operations or cash flows. Financial Risks Foreign exchange risks and fluctuations may affect our profitability on certain projects. We operate on a worldwide basis with substantial operations outside the United States that subject us to U.S. dollar translation and economic risks. In order to manage some of the risks associated with foreign currency exchange rates, we may enter into foreign currency derivative (hedging) instruments, especially when there is currency risk exposure that is not naturally mitigated via our contracts. However, these actions may not always eliminate all currency risk exposure, in particular for our long-term contracts. A disruption in the foreign currency markets, including disruptions that may occur from time to time as a result of economic policies of foreign governments or central banks, could adversely affect our hedging instruments and subject us to additional currency risk exposure. Based on fluctuations in currency, the U.S. dollar value of our backlog may from time to time increase or decrease significantly. We do not enter into derivative instruments for trading or other speculative purposes. Our operational cash flows and cash balances, though predominately held in U.S. dollars, may consist of different currencies at various points in time in order to execute our contracts globally. Non-U.S. asset and liability balances are subject to currency fluctuations when measured period to period for financial reporting purposes in U.S. dollars. Maintaining adequate letter of credit and bonding capacity is necessary for us to successfully bid on and win various contracts. In line with industry practice, we are often required to post standby letters of credit to customers or enter into surety bond arrangements in favor of customers. Those letters of credit and surety bond arrangements generally protect customers against our failure to perform our obligations under the applicable contracts. However, the terms of those letters of credit, including terms relating to the customer’s ability to draw upon the letter of credit and the amount of the letter of credit required, can vary significantly. If a letter of credit or surety bond is required for a particular project and we are unable to obtain it due to insufficient liquidity or other reasons, we may not be able to pursue that project. We have limited capacity for letters of credit, and we rely substantially on bilateral letters of credit from various issuing banks in a number of markets. Moreover, due to events that affect the credit markets generally, letters of credit may be more difficult to obtain in the future or may only be available at significant additional cost. Letters of credit, including through our bilateral arrangements (which are cancelable in the discretion of the issuing banks), may not continue to be available to us on reasonable terms. Our inability to obtain adequate letters of credit and surety bonds and, as a result, to bid on new work could have a material adverse effect on our business, cash flows, liquidity, financial condition and results of operations. Significant inflation and higher interest rates could adversely affect our business and financial condition. The United States experienced inflationary pricing and increasing construction and labor costs in 2023 and 2022. While the pace of inflation has reduced since 2022, future changes in inflation could have an adverse impact on our business and our financial condition by increasing our costs of materials and labor. In addition, changing and future monetary policies and actions of the Federal Reserve that result from such adverse market and economic conditions (such as raises to the target federal funds rate) could adversely affect our ability to obtain financing and raise our (or our customers’) cost of capital. In a highly inflationary environment, we may be unable to raise pricing for our energy services and products at or above the rate of inflation, which could reduce our profit margins and our 21
Page 24
Table of Contents/ cost of capital, labor and materials could increase, which could have an adverse impact on our business and our financial condition. Difficulty in obtaining sufficient capital could adversely impact our business and financial condition. A financial crisis or economic recession could have an adverse impact on our business and our financial condition. In particular, the cost of capital could increase substantially and the availability of funds from the capital markets could diminish significantly. Credit and capital markets have, from time to time, experienced volatility. Our ability to access the capital markets in the future could be restricted or available on terms we do not consider favorable. Limited access to the capital markets could adversely impact our ability to take advantage of business opportunities or react to changing economic and business conditions and could adversely impact our ability to continue our growth strategy. If one or more of the lenders under our revolving credit facility were to become unable or unwilling to perform their obligations under that facility, our borrowing capacity could be reduced. Our inability to borrow under our revolving credit facility could limit our ability to fund our future operations and growth. Ultimately, we could be required to reduce our future capital expenditures substantially and such a reduction could have a material adverse effect on our business and our consolidated financial condition, results of operations and cash flows. A financial crisis or economic recession could also affect our suppliers and our customers, causing them to fail to meet their obligations to us, which could have a material adverse effect on our revenue, income from operations and cash flows. In addition, we maintain our cash balances and short-term investments primarily in accounts held by major banks and financial institutions located principally in North America, Europe, Africa and Asia, and some of those accounts hold deposits that exceed available insurance. It is possible that one or more of the financial institutions in which we hold our cash and investments could become subject to bankruptcy, receivership or similar proceedings. As a result, we could be at risk of not being able to access material amounts of our cash, which could result in a temporary liquidity crisis that could impede our ability to fund operations. Strategic Risks Related to our Business Our business strategy contemplates future acquisitions or dispositions. Acquisitions of other businesses or assets and dispositions of our current businesses or assets present various risks and uncertainties. We may pursue growth through the acquisition of businesses or assets that will enable us to broaden our service and product offerings and expand into new markets, and, from time to time, we may also consider dispositions of non-strategic assets. We may be unable to implement this element of our growth strategy or our long-term strategy if we cannot identify suitable businesses or assets, reach agreement on potential strategic acquisitions on acceptable terms or for other reasons, or obtain the fair value of the assets or businesses we may sell. Moreover, acquisitions and dispositions involve various risks, including: • difficulties relating to the assimilation of personnel, services and systems of an acquired business and the assimilation of marketing and other operational capabilities; • challenges resulting from unanticipated changes in customer and other third-party relationships subsequent to acquisition; • additional financial and accounting challenges and complexities in areas such as tax planning, treasury management, financial reporting and internal controls; • assumption of liabilities of an acquired business, including liabilities that were unknown at the time the acquisition transaction was negotiated; • future realizability of noncash consideration; • possible liabilities under the FCPA and other anti-corruption laws; • diversion of management's attention from day-to-day operations; • failure to realize anticipated benefits, such as cost savings and revenue enhancements; • potentially substantial transaction costs associated with acquisitions; and • potential impairment resulting from the overpayment for an acquisition. Future acquisitions may require us to obtain additional equity or debt financing, which may not be available on attractive terms. Moreover, to the extent an acquisition transaction financed by non-equity consideration results in goodwill, it will reduce our tangible net worth, which might have an adverse effect on credit availability. 22
Page 25
Table of Contents/ Additionally, an acquisition may bring us into businesses we have not previously conducted and expose us to additional business risks that are different from those we have previously experienced. Our business strategy also includes development and commercialization of new technologies to support our growth. The development and commercialization of new technologies require capital investment and involve various risks and uncertainties. Our future growth will depend on our ability to continue to innovate by developing and commercializing new service and product offerings. Investments in new technologies involve varying degrees of uncertainties and risk. Commercial success depends on many factors, including the levels of innovation, the development costs and the availability of capital resources to fund those costs, the levels of competition from others developing similar or other competing technologies, our ability to obtain or maintain government permits or certifications, the effectiveness of production, distribution and marketing efforts, and the costs to customers to deploy and provide support for the new technologies. We may not achieve significant revenue from new service and product investments for a number of years, if at all. Moreover, new services and products may not be profitable, and, even if they are profitable, our operating margins from new services and products may not be as high as the margins we have experienced historically. The loss of the services of one or more of our key personnel, or our failure to attract, assimilate and retain trained personnel in the future, could disrupt our operations and result in loss of revenue. Our success depends on the continued active participation of our executive officers and key operating personnel. The unexpected loss of the services of any one of these persons could adversely affect our operations. Our operations require the services of employees having the technical training and experience necessary to obtain the proper operational results. As a result, if we should suffer any material loss of personnel to competitors or be unable to employ additional or replacement personnel with the requisite level of training and experience to adequately operate our equipment, our operations could be adversely affected. A significant increase in the wages paid by other employers could result in a reduction in our workforce, increases in wage rates, or both. We may not be able to compete successfully against current and future competitors, particularly competitors that may have substantially greater financial, technical and personnel resources than we do. Our businesses operate in highly competitive industry segments. Some of our competitors or potential competitors have greater financial, technical, personnel or other resources than we have. Our operations may be adversely affected if our current competitors or new market entrants introduce new products or services with better features, performance, prices or other characteristics than those of our services and products. Additionally, our competitors may have better access to financial and capital markets on more favorable terms than we are able to obtain due to their relative size or balance sheets. As a result, our cost of capital could increase substantially, and the availability of funds from the capital markets could diminish significantly, as compared to our competitors. These factors may be significant to our segments' operations, particularly in the operating segments within our Energy business, where capital investment is critical to our ability to compete. Our aspirations, goals, commitment targets and initiatives related to sustainability, including emissions reduction and our public statements and disclosures regarding the same, expose us to numerous risks. We have developed, and we will continue to develop, goals, targets and other objectives related to sustainability matters, including our 2030 emission reduction targets. Statements related to these goals, targets and objectives are made using various underlying assumptions and reflect our current intentions, and do not constitute a guarantee that they will be achieved. Our efforts to research, establish, accomplish and accurately report on these goals, targets and other objectives expose us to numerous operational, reputational, financial, legal and other risks. Our ability to achieve any stated goal, target or objective is subject to numerous factors and conditions, many of which are outside of our control, including the availability of alternative energy sources in the jurisdictions in which we operate, the capacity of electrical grids to support traditional and alternative energy sources, and the broader economic and legal circumstances affecting energy and electricity locally. We cannot predict the ultimate impact of achieving our 2030 emissions reduction targets, or the various implementation aspects, on our financial condition and results of operations. Our business may face increased scrutiny from investors and other stakeholders related to our sustainability activities, including the goals, targets and other objectives that we announce, and our methodologies and timelines for pursuing them. If our sustainability assumptions or practices do not meet investor or other stakeholder 23
Page 26
Table of Contents/ expectations and standards, which continue to evolve, our reputation, our ability to attract or retain employees and our attractiveness as an investment or business partner could be negatively affected. Similarly, our failure or perceived failure to pursue or fulfill our sustainability focused goals, targets and objectives, to comply with ethical, environmental or other standards, regulations or expectations, or to satisfy various reporting standards with respect to these matters, within the timelines we announce, or at all, could adversely affect our business or reputation, as well as expose us to government enforcement actions and private litigation. Risks Related to Intellectual Property, Information Technology and Data Privacy We rely on intellectual property law and confidentiality agreements to protect our intellectual property. We also rely on intellectual property we license from third parties. Our failure to protect our intellectual property rights, or our inability to obtain or renew licenses to use intellectual property of third parties, could adversely affect our business. We rely on a variety of intellectual property rights that we use in our services and products, and our success depends, in part, on our ability to protect our proprietary information and other intellectual property. Our intellectual property could be challenged, invalidated, circumvented or rendered unenforceable. In addition, effective intellectual property protection may be limited or unavailable in some foreign countries where we operate. Our failure to protect our intellectual property rights may result in the loss of valuable technologies or adversely affect our competitive business position. We rely significantly on proprietary technology, information, processes and know-how that are not subject to patent or copyright protection. We seek to protect this information through trade secret or confidentiality agreements with our employees, consultants, subcontractors or other parties, as well as through other security measures. These agreements and security measures may be inadequate to deter or prevent misappropriation of our confidential information. In the event of an infringement of our intellectual property rights, a breach of a confidentiality agreement or divulgence of proprietary information, we may not have adequate legal remedies to protect our intellectual property. In some instances, we have augmented our technology base by licensing the proprietary intellectual property of third parties. However, it is possible that the tools, techniques, methodologies, programs and components we use to provide our services or products may infringe on the intellectual property rights of others. In the future, we may not be able to obtain necessary licenses on commercially reasonable terms. Royalty payments under licenses from third parties, if available, or developing non-infringing technologies could materially increase our costs. Additionally, if a license or non-infringing technology were not available, we might not be able to continue providing a particular service or product, which could materially and adversely affect our financial condition, results of operations and cash flows. Litigation to determine the scope of intellectual property rights, even if ultimately successful, could be costly and could divert management's attention away from other aspects of our business. In addition, our trade secrets may otherwise become known or be independently developed by competitors. Our informational technology (“IT”) and operational technology (“OT”) systems are subject to interruption and cybersecurity risks that could adversely impact our operations. Our operations (both onshore and offshore) are highly dependent on both IT and OT systems and personnel that implement and maintain such systems, including systems that collect, process, store or use personal information, confidential or proprietary information, and other sensitive information about our business and operations, as well as our customers, employees, suppliers and others. Some of these systems are managed or provided by third-party service providers, including certain cloud platform or cloud software providers. As a result, our business operations could be negatively impacted by a breach or interruption of systems that originates from, or compromises, third-party networks or devices outside of our control. We have experienced cyber incidents in the past and, although none have been material, we may experience cybersecurity incidents and security breaches in the future. Threats to our IT and OT systems associated with cybersecurity risks, cyber incidents and cyberattacks continue to grow in sophistication and scale. Risks associated with these threats include disruptions of certain systems on our vessels or systems utilized to operate our ROVs; other impairments of our ability to conduct our operations; interruption of internal critical services; interruption of external critical services to customers; interruption of our ability to bill or collect payment from customers; loss of or damage to intellectual property, proprietary information or employee or customer data; disruption of our customers’ operations; loss or damage to our employee or customer data delivery systems; damage to our reputation or customer or other business relationships; inability to comply with our contractual or regulatory obligations in a timely 24
Page 27
Table of Contents/ manner which could result in civil litigation, regulatory investigations or other enforcement actions by governmental authorities and associated costs, fines or penalties; increased costs to prevent, respond to or mitigate cybersecurity incidents; and diversion of management or work force attention. Such a cyber incident could have a material adverse effect on our business and our consolidated financial condition, results of operations and cash flows. In addition, certain cyberattacks and related incidents, such as reconnaissance or surveillance by threat actors, may remain undetected for an extended period notwithstanding our monitoring and detection efforts. The increased use of artificial intelligence by threat actors has amplified risks, as AI-driven cyberattacks can automate the discovery of vulnerabilities, generate highly convincing phishing attempts, and evade traditional detection methods. These capabilities may enable attackers to mount more effective and persistent campaigns against our infrastructure. As a result, we may be required to incur additional costs to modify or enhance our IT or OT systems to prevent or remediate any such attacks. While we continue to evaluate potential replacements or upgrades of existing systems, the implementation of new systems or upgrades to existing systems subjects us to inherent costs and risks associated with replacing or changing these systems, including potential disruption of our internal control structure, substantial capital expenditures, demands on management time and other risks. In addition, potential upgrades or updates may not result in productivity improvements at the levels anticipated, or at all. Moreover, the implementation of new, updated, or upgraded systems may cause disruptions in our business operations. Any such disruption, and any other system disruptions, if not anticipated and appropriately mitigated, could have a material adverse effect on our operations. Finally, laws and regulations we may be subject to governing cybersecurity, such as obligations under the Cyber Incident Reporting for Critical Infrastructure Act, pose increasingly complex compliance challenges, and failure to comply with these laws and regulations could result in fines, penalties, legal liability and damage to our reputation and customer or other business relationships. Changes in data privacy and security laws, regulations and standards, and emerging laws, regulations and standards surrounding artificial intelligence (“AI”), may adversely impact our business. Data privacy and security have become significant regulatory issues and the subject of rapidly evolving laws globally and in the United States. As a result, we are subject to a growing patchwork of privacy regulations imposed by jurisdictions where we operate, including under the European Union’s and U.K.’s General Data Protection Regulation, Brazil’s General Data Protection Law and in the United States under various state privacy frameworks, such as the California Consumer Privacy Act, the Texas Data Privacy and Security Act, and many more. These regulatory frameworks apply to activities related to the collection, use, disclosure, and transfer of personal data that may be conducted by us or directly or indirectly through our vendors or subcontractors. Data privacy and security regulations may significantly impact our business activities and require substantial compliance costs that adversely affect our business, operating results, prospects and financial condition. Additionally, any failure by us to comply with these regulations, including as a result of a personal data breach, could result in significant penalties and liabilities for us. Interpretations and enforcement of these laws continue to evolve, and changes to these regulatory interpretations or enforcement of these laws could create a range of new compliance obligations, which could cause us to incur additional costs. Furthermore, foreign, federal, state and local government bodies or agencies have, in the past, adopted —and may in the future adopt—more laws and regulations affecting data privacy and security. Although these privacy and security laws share similar concepts, each applicable jurisdiction may include important variations, such as differing standards or obligations. Those variations may increase our compliance costs and place increased demand on our resources by creating complex monitoring, control and compliance challenges. Any failure by us to comply with these laws and regulations, including as a result of a personal data breach, could result in significant penalties and liabilities for us. Our business and operations could become subject to future legislation, regulation, enforcement strategies and regulatory or judicial interpretations beyond those currently proposed, adopted or contemplated in the U.S. and abroad. Emerging regulatory trends, particularly regarding AI, present new challenges. Furthermore, the costs of compliance with, and other burdens imposed by, the laws, regulations, and policies, such as audits and data transfer restrictions that could be applicable to our business, may limit the use and adoption of, and reduce the overall demand for, our solutions. Finally, if we acquire an entity that has violated or is not in compliance with applicable data privacy and, security laws or regulations (or contractual provisions), we may experience similar adverse consequences. 25

Table of Contents/ Risks Related to our Organization and Structure We may issue preferred stock whose terms could adversely affect the voting power or value of our common stock. Our certificate of incorporation authorizes us to issue, without the approval of our shareholders, one or more classes or series of preferred stock having such preferences, powers and relative, participating, optional and other rights, including preferences over our common stock respecting dividends and distributions, as our board of directors may determine. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of our common stock. For example, we might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock could affect the residual value of the common stock. Provisions in our corporate documents and Delaware law could delay or prevent a change in control of our company, even if that change would be beneficial to our shareholders. The existence of some provisions in our corporate documents and Delaware law could delay or prevent a change in control of our company, even if that change would be beneficial to our shareholders. Our certificate of incorporation and bylaws contain provisions that may make acquiring control of our company difficult, including: • provisions relating to the classification, nomination and removal of our directors; • provisions regulating the ability of our shareholders to bring matters for action at annual meetings of our shareholders; • provisions requiring the approval of the holders of at least 80% of our voting stock for a broad range of business combination transactions with related persons; and • the authorization given to our board of directors to issue and set the terms of preferred stock. In addition, the Delaware General Corporation Law imposes restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. General Risks Our internal controls may not be sufficient to achieve all stated goals and objectives. Our internal controls and procedures were developed through a process in which our management applied its judgment in assessing the costs and benefits of such controls and procedures, which, by their nature, can provide only reasonable assurance regarding the control objectives. The design of any system of internal controls and procedures is based, in part, on various assumptions about the likelihood of future events. We cannot assure that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. The use of estimates could result in future adjustments to our assets, liabilities and results of operations. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that our management make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Item 1B. Unresolved Staff Comments. None. Item 1C. Cybersecurity. Risk Management and Strategy. Oceaneering continues to make cybersecurity a priority as the threat landscape evolves and becomes increasingly complex and sophisticated. Managing Material Risks & Integrated Overall Risk Management The Company has strategically integrated cybersecurity risk management into its broader risk management framework to promote a company-wide culture of cyber risk awareness. Our Chief Information Technology Officer (“CITO”) and Chief Information Security Officer (“CISO”) work closely with our Enterprise Risk Committee to 26
Page 29
Table of Contents/ continuously evaluate and address cyber risks in alignment with business objectives, operational needs and industry- accepted standards, such as the National Institute of Standards and Technology (“NIST”) and the Cybersecurity Maturity Model Certification (“CMMC”) frameworks. The Company has processes and procedures in place to monitor the prevention, detection, mitigation and remediation of cybersecurity risks. These include but are not limited to: • Maintaining a defined and practiced incident response plan with dedicated Cybersecurity Event Response and Corporate Crisis Management Teams, including maintaining a 24/7 security operations center (“SOC”); • Maintaining cyber insurance coverage; • Employing appropriate incident prevention and detection safeguards; • Maintaining a defined disaster recovery policy and employing disaster recovery software, where appropriate; • Educating, training and testing our user community on information security practices and identification of potential cybersecurity risks and threats; and • Reviewing and evaluating new developments in the cyber threat landscape. Engaging Third Parties on Risk Management Recognizing the complexity and evolving nature of cybersecurity risk, Oceaneering engages with a range of external support, including cybersecurity consultants, in evaluating, monitoring and testing our cyber management systems and related cyber risks. The Company’s collaboration with these third parties includes audits, threat and vulnerability assessments, incident response plan testing, company-wide monitoring of cybersecurity risks and consultation on security enhancements. Managing Third Party Risk Oceaneering recognizes the risks associated with the use of vendors, service providers and other third parties that provide information system services to us, process information on our behalf, or have access to our information systems, and the Company has processes in place to oversee and manage these risks. We conduct thorough risk-weighted security assessments of various third parties and maintain ongoing monitoring to ensure compliance with our cybersecurity standards. This monitoring includes both annual assessments and assessments on an ongoing basis.

Table of Contents/ Part II Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities. Our common stock is listed on the New York Stock Exchange under the symbol “OII.” Our company website address is www.oceaneering.com. On February 13, 2026, there were approximately 222 holders of record of our common stock. On that date, the closing sales price, as quoted on the New York Stock Exchange, was $33.15. Although our Board has not declared quarterly dividends since 2017, we review our dividend position on a quarterly basis. The payment of future dividends will depend on our results of operations, financial condition, cash requirements, future business prospects, contractual and indenture restrictions and other factors deemed relevant by our Board of Directors. In December 2014, our Board of Directors approved a plan to repurchase up to 10 million shares of our common stock on a discretionary basis. The program calls for any repurchases to be made in the open market, or in privately negotiated transactions from time to time, in compliance with applicable laws, rules and regulations, including Rule 10b-18 under the Securities Exchange Act of 1934, as amended, subject to market and business conditions, levels of available liquidity, cash requirements for other purposes, applicable legal requirements and other relevant factors. The timing and amount of any repurchases will be determined by management based on its evaluation of these factors. We expect that any shares repurchased under the program will be held as treasury stock for future use. The program does not obligate us to repurchase any particular number of shares and it has no expiration date. Under the program, we had repurchased 2.0 million shares of our common stock for approximately $100 million through December 31, 2015. We did not repurchase any shares from January 2016 through August 2024. In the year ended December 31, 2024, we repurchased 0.8 million shares of our common stock for approximately $20 million. In the year ended December 31, 2025, we repurchased 1.8 million shares of our common stock for approximately $40 million. From the inception of this program through December 31, 2025, we have repurchased approximately 4.6 million shares of our common stock for a total cost of approximately $161 million. As of December 31, 2025, we had 5.4 million shares remaining for repurchase under the December 2014 authorization. Repurchases of Equity Securities. Share repurchase activity during the three-month period ending December 31, 2025, was as follows: Period Total Number ofSharesPurchased Average PricePaid perShare Total Number ofShares Purchased asPart of PubliclyAnnounced Plans orPrograms Maximum Number ofShares That May YetBe Purchased Underthe Plans orPrograms October 1 - 31, 2025 — $ — — 5,782,846 November 1 - 30, 2025 365,400 $ 23.98 365,400 5,417,446 December 1 - 31, 2025 53,605 $ 24.05 53,605 5,363,841 419,005 419,005 (1) All purchases during the covered periods were made under the share repurchase program, which was approved by our Board of Directors in December 2014 and which authorized the repurchase of up to 10 million shares of our common stock on a discretionary basis. Under the program, which has no expiration date, we had repurchased 2,000,000 shares for approximately $100 million through December 31, 2015, 825,427 shares for approximately $20 million in the year ended December 31, 2024, and 1,810,732 shares for approximately $40 million in the year ended December 31, 2025.

Table of Contents/ Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations. The following information should be read in conjunction with the information contained in “Part I. Item 1. Business,” “Part I. Item 1A. Risk Factors” and the audited consolidated financial statements and the notes thereto included under “Item 8. Financial Statements and Supplementary Data” elsewhere in this annual report on Form 10-K. For management's discussion and analysis of our financial condition and results of operations for fiscal year 2024 as compared to fiscal year 2023, please refer to Part II, Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Form 10-K and Form 10-K/A for the fiscal year ended December 31, 2024, filed with the Securities and Exchange Commission ("SEC") on February 24, 2025 and March 4, 2025, respectively. Certain statements in this annual report on Form 10-K, including, without limitation, statements regarding the following matters, are forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995: • our business strategy; • industry conditions and commodity pricing; • seasonality; • our expectations about 2026 revenue and results of operations, including items below the income from operations (“operating income”) line and segment operating results, and the factors underlying those expectations, including our expectations about demand and pricing for our energy services and products as a result of the factors we specify in “Overview of our Results” and “Results of Operations” below; • our ability to successfully manage the integration of acquisitions, including the realization of synergies and opportunities for growth and innovation, and the challenges of divestitures; • our expectations about the balance between energy transition and energy security; • our emissions reduction targets; • our backlog, to the extent backlog may be an indicator of future revenue or productivity; • projections relating to floating rig demand and subsea tree installations; • our expectations about our ROV fleet utilization, pricing and margins in the future; • the adequacy of our sources of liquidity, cash flows and capital resources to support our operations and internally generated growth initiatives; • the collectability of accounts receivable and realizability of contract assets at the amounts reflected on our most recent balance sheet; • our future working capital needs and our projected capital expenditures for 2026; • transactions we may engage in to manage our outstanding debt prior or maturity; • our plans for future operations (including planned additions to and retirements from our remotely operated vehicle (“ROV”) fleet); • our ability and intent to repatriate cash from foreign countries where we have operations; • our expectations regarding shares that may be repurchased under our share repurchase plan; and • our expectations regarding the implementation of new accounting standards and related policies, procedures and controls. These forward-looking statements are subject to various risks, uncertainties and assumptions, including those we refer to under the headings “Cautionary Statement Concerning Forward-Looking Statements” and “Risk Factors” in Part I of this report. Although we believe that the expectations reflected in such forward-looking statements are reasonable, because of the inherent limitations in the forecasting process, as well as the relatively volatile nature of the industries in which we operate, we can give no assurance that those expectations will prove to have been correct. Accordingly, evaluation of our future prospects must be made with caution when relying on forward-looking information. Our Engagement in the Energy Transition Oceaneering currently generates a substantial majority of its revenue from the oil and gas sector. Due to the continuing development of economies in developing countries, substantial projected population growth (particularly in developing countries), and the shortage of other sources of affordable, reliable, scalable and efficient energy, as well as rising worldwide demand for a myriad of products made with petrochemicals, we expect that the need for 33
Page 36
Table of Contents/ additional oil and gas exploration and development and inspection, maintenance and repair (“IMR”) activities will continue for decades to come. At the same time, due to increasing concerns about climate change, there is growing demand for cleaner hydrocarbon-based and renewable energy sources. We strive to meet the growing need for lower-carbon energy by assisting customers to reduce their carbon emissions in exploring for, developing and producing oil and natural gas, while also diversifying our business into new strategic growth areas in emerging energy and non-energy markets. We believe this measured approach ensures our resilience in an ever-changing market. Today, the impacts of climate-related risks and opportunities and balancing energy security with energy transition are influencing our strategy in the following ways: • we are continuing to support our customers in producing oil and natural gas to meet global demand for energy, while developing methods to minimize their carbon footprint through increased efficiency and technological innovation; • we are deploying our competencies and capabilities to serve the energy-transition markets, including those utilizing offshore wind installations (fixed and floating), nuclear, hydrogen, carbon capture and sequestration, and tidal energy technologies; and • we are diversifying our businesses outside the energy industry into new strategic growth areas, such as mobility solutions and digital asset management, as well as increasing our participation in the defense and aerospace sectors. We are committed to the research and development of products and services designed to assist our Energy business (defined below) customers in producing energy safely and securely, with decreased risk to humans and marine life, and reduced environmental impacts. For example, we established our first Onshore Remote Operation Center (“OROC”) in Norway in 2015 and have since set up additional dedicated sites in the United States (“U.S.”), Brazil and United Kingdom (“U.K.”) OROCs enable customers to reduce their carbon footprint by relocating offshore workers to onshore control centers, thereby enhancing human health and safety, fostering greater collaboration and enabling faster responses to real-time events. We are also committed to reducing our own energy consumption and the greenhouse gas emissions attributable to our operations. With the help of a third-party consultant over the past several years, we performed a global review of our assets and operations and identified our Scope 1 and Scope 2 emissions for our 2022 baseline in accordance with best practice greenhouse gas accounting methodologies, including the Greenhouse Gas Protocol. In 2023, we established and announced our 2030 greenhouse gas Scope 1 and Scope 2 emission reduction targets against a 2022 baseline. Our 2025 Task Force on Climate-Related Financial Disclosures Report (the “TCFD Report,” which is not incorporated by reference in this Annual Report) outlines our continued commitment to managing the risks and opportunities from climate change and contains our emissions reduction targets as well as our 2022, 2023 and 2024 Scope 1 and Scope 2 greenhouse gas emissions data. Our capital investments and expenses required to achieve our goals cannot be estimated at this time. Overview of Our Results The table that follows sets out our revenue and operating income for 2025 and 2024. Year Ended December 31, (dollars in thousands) 2025 2024 Revenue $ 2,784,156 $ 2,661,161 Operating Income (Loss) 304,552 246,270 Operating Income (Loss) % 11 % 9 % Net Income (Loss) 353,761 147,468 We operate in five business segments. Our business segments are contained within two businesses—services and products provided primarily to the oil and gas industry and, to a lesser extent, the mobility solutions and offshore renewables industries, among others (“Energy”), and services and products provided to non-energy industries (“Aerospace and Defense Technologies” or “ADTech”). Our four business segments within the Energy business are Subsea Robotics, Manufactured Products, Offshore Projects Group (“OPG”) and Integrity Management & Digital Solutions (“IMDS”). We report our ADTech business as one segment. Our Unallocated Expenses are expenses not associated with a specific business segment. These consist of expenses related to our incentive and deferred compensation plans, including restricted stock units, performance units and bonuses, as well as other general expenses, including corporate administrative expenses. 34
Page 37
Table of Contents/ Our business primarily depends on the level of spending on offshore developments and related operating activities by our customers in the energy industry. Compared to 2024, our 2025 revenue increased 5% to $2.8 billion, with revenue growth in all of our operating segments, except IMDS. Consistent with the prior year, we generated a substantial majority of our revenue from services and products we provided to the energy industry in 2025. Consolidated operating income improved during 2025 as compared to 2024 with increases in all of our segments. We had operating income of $305 million in 2025 and operating income of $246 million in 2024. In 2025, on a consolidated level, we had net income of $354 million, or diluted earnings of $3.49 per share, compared to net income of $147 million, or diluted earnings of $1.44 per share, in 2024. The increases in 2025 operating income as compared to 2024 were primarily due to higher revenue in all of our segments, except for IMDS, as a result of the realization of improved pricing in energy markets and growth in our energy businesses. The increase in net income and diluted earnings per shares in 2025 as compared to 2024, was due to increased operating income, along with an income tax benefit resulting primarily from the release of U.S. valuation allowances. All of our segments achieved improved sequential annual operating income, led by our Manufactured Products segment. During the year ended December 31, 2025, our cash balance increased $191 million as compared to December 31, 2024. We generated $319 million from operating activities, along with a $14 million cash increase as a result of favorable movements in exchange rates, and the sale of a vessel in 2025 for $8.9 million. Partially offsetting these increases were $57 million maintenance capital expenditures, $54 million of growth capital expenditures and $40 million for repurchases of shares of our common stock. We use our ROVs to provide drill support, vessel-based IMR, subsea hardware installation, construction, and pipeline inspection services to customers in the energy industry. Most of our ROVs have historically been used to provide drill support services. Therefore, the contracted number of floating drilling rigs is a leading market indicator for this business. The following table shows average floating rigs under contract and our ROV utilization. 2025 2024 Average number of floating rigs under contract 137 146 ROV days on hire (in thousands) 60 61 ROV utilization 65 % 67 % Demand for floating rigs is a leading indicator of the strength of the deepwater market. According to comprehensive industry data compiled and published by a leading provider of financial data and market intelligence, excluding rigs under construction, at the end of 2025 there were 186 floating drilling rigs in operation or available for work throughout the world, with 136 of those rigs under contract. The average contracted offshore floating rig count in 2025 decreased by 6.2% to approximately 137 rigs. Outlook In 2026, we expect ADTech to be our primary growth engine, supported by our existing backlog and increased spending across defense and government markets. We anticipate results in our energy-focused businesses to be weighted towards the second half of the year as offshore activity improves. For our energy-focused businesses, we expect 2026 financial results to reflect a global oil market that remains oversupplied through the early part of the year, with gradual tightening as the year progresses and as demand continues to rise. The number of subsea tree orders and installations is a leading indicator and is the primary demand driver for our Manufactured Products lines. According to data published by a world-leading analysis and consultancy company for the energy sector in December 2025, there are projected to be 306 tree awards and 370 subsea tree installations in 2026, compared to 190 tree awards and 343 installations in 2025 and 218 tree awards and 296 installations in 2024. In our defense business, we expect another strong year supported by sustained U.S. prioritization of maritime security, unmanned systems, and industrial-base modernization. Domestically, we see steady activity across subsea critical infrastructure protection, unmanned maritime systems, and submarine sustainment. Internationally, rising geopolitical tensions and increased allied spending continue to expand opportunities for our autonomous underwater vehicles (“AUVs”), resident systems, and subsea monitoring solutions. Based on our 2025 year-end backlog conversion, anticipated 2026 order intake and current market fundamentals, we project that our 2026 consolidated revenue will increase. For 2026, we project revenue growth in our ADTech. Subsea Robotics and IMDS segments, driven by our expectations for continued pricing progression and favorable 35
Page 38
Table of Contents/ year over year project mix. We forecast operating income growth for all of our segments, except for OPG. We will continue to prioritize safety and quality, while maintaining disciplined portfolio management and capital allocation. For our Subsea Robotics segment, we expect slightly improved revenue and relatively flat operating income in 2026 based on stable pricing for ROVs, increased volume in Tooling and improved results in our Survey business. We expect improvements in operating income on slightly lower revenue in our Manufactured Products segment in 2026, primarily due to the continued conversion of our existing backlog in energy products and benefits from cost reductions enacted in 2025 in our non-energy product lines. Our Manufactured Products backlog was $511 million as of December 31, 2025. We expect revenue and operating income for our OPG segment to decrease significantly in 2026 due to lower activity levels in the U.S. Gulf and West Africa, partially offset by higher activity levels in the Caspian and Middle East regions and Brazil. We anticipate our 2026 operating income for IMDS will improve significantly on higher revenue, with growth opportunities in digital and engineering services. We project our ADTech 2026 operating income to increase on significantly higher revenue as compared to 2025, driven by growth in all three of our government-focused businesses. For 2026, we anticipate Unallocated Expenses to average approximately $50 million per quarter, with the year-over year increase primarily due to higher costs associated with wage inflation, increased information technology costs, and foreign exchange impacts. Results of Operations Additional information on our business segments is shown in Note 10—“Operations by Business Segment and Geographic Area” in the Notes to Consolidated Financial Statements included in this report. Energy. The table that follows sets out revenue and profitability for the business segments within our Energy business. In the Subsea Robotics section of the table that follows, “ROV Days Utilized” is the number of ROV days for which we earn revenue during a specified period. “ROV Days Available” includes all days from the first day that an ROV is placed in service until the ROV is retired. All days in this period are considered available days, including periods when an ROV is undergoing maintenance or repairs. Our ROVs do not have scheduled maintenance or repair that requires significant time when the ROVs are not available for utilization. “ROV utilization” percentage is defined as “ROV days utilized” divided by “ROV days available.” 36

We believe we are the world's largest provider of work-class ROV services and this business segment is the largest contributor to our Energy business operating income. Our ROV business, within our Subsea Robotics segment, reflects the utilization percentages, fleet sizes and average pricing in the respective periods. Our ROV tooling provides an additional operational interface between an ROV and equipment located subsea. Our survey services business provides survey, positioning and geoscience services. The following table presents revenue from ROV services as a percentage of total Subsea Robotics revenue: Year ended December 31, 2025 2024 ROV 78 % 78 % Other 22 % 22 % For the year ended December 31, 2025, our Subsea Robotics operating income increased as compared to 2024, on higher revenue, as a result of higher average revenue per day for our ROV business and increased pricing and volume for tooling on our existing ROV contracts. Partially offsetting these increases were decreased activity levels in our survey business primarily due to drydocking of our survey vessel in 2025. We had lower days on hire for the year ended December 31, 2025, as compared to 2024, that included a year-over-year decrease in drill support days in the first half of 2025 and relatively flat vessel support days. Fleet utilization was 65% in the year ended December 31, 2025, as compared to 67% for the year ended December 31, 2024, resulting primarily from a decrease in ROV days utilized when compared to the corresponding period in the prior year, based on lower market activity. Our ROV fleet use during the year ended December 31, 2025, was 64% in drill support and 36% in vessel-based activity, as compared to 65% in drill support and 35% in vessel-based activity in the prior year. For each of the periods presented, we had a fleet of 250 work-class ROVs. 37
Page 40
Table of Contents/ Manufactured Products. For the year ended December 31, 2025, our Manufactured Products revenue and operating income increased, as compared to 2024, primarily due to increased activity in our energy-related businesses, execution on higher- margin backlog through our umbilical manufacturing plants and growth in our Grayloc business, partially offset by an inventory reserve of $13 million recorded in 2025 related to our theme park ride business. Our Manufactured Products backlog was $511 million as of December 31, 2025, a $93 million, or 15%, decrease from December 31, 2024. Our book-to-bill ratio was 0.84 for the year ended December 31, 2025, as compared with a book-to-bill ratio of 0.97 for the year ended December 31, 2024. Offshore Projects Group. Our OPG operating income for the year ended December 31, 2025 increased as compared to 2024, on higher revenue primarily due to an improved mix of well intervention and installation work in the U.S. Gulf, along with a reduction in drydock expense and the associated loss of vessel days that impacted the first quarter of 2024, partially offset by a reduction in international activity. We have several deepwater vessels under a mix of short-term charters where we can see firm workload and spot charters as market opportunities arise. We have a total of five long-term charters as of December 31, 2025: one that began in 2024, two that began in 2023, and two that began in 2022. We signed extensions in the third quarter of 2025 for three of these long-term vessel charters that began in the first quarter of 2026. These charters have staggered maturity dates with none extending past the first quarter of 2029. Depending on market conditions, we may add additional chartered vessels throughout the year to align with our strategy that balances vessel cost, availability and capability to capture work. We expect to do this through the continued utilization of a mix of short-term, spot and long-term charters. Integrity Management & Digital Solutions. For the year ended December 31, 2025, compared to 2024, our IMDS operating income increased on lower revenue, primarily due to the absence of a one-time, non-cash charge associated with the divestiture of our Maritime Intelligence division in September 2024. Aerospace and Defense Technologies. Revenue and operating income information for our ADTech segment are as follows: Year ended December 31, (dollars in thousands) 2025 2024 Revenue $ 459,904 $ 392,936 Operating Income 57,744 42,201 Operating Income % 13 % 11 % For the year ended December 31, 2025, compared to 2024, our ADTech segment operating income increased on higher revenue, primarily due to increased activity and margins in our Oceaneering Technologies (“OTECH”) and Marine Services Division, along with additional expenses and a reserve related to a contract dispute that were taken in 2024 and reversed in 2025 due to a subsequent change in estimate. Partially offsetting these increases were lower activity levels in our Oceaneering Space Systems businesses. As previously disclosed, we are in discussions with an ADTech customer regarding a contract dispute. The dispute is not currently the subject of pending litigation, and the amount of any loss or other damages, if any, arising from the dispute will depend on multiple factors. Unallocated Expenses. Our unallocated expenses, (i.e., those not associated with a specific business segment), within operating expenses consist of expenses related to our incentive and deferred compensation plans, including restricted stock units, performance units and bonuses, as well as other general expenses, plus general and administrative expenses related to corporate functions. 38

The following table sets forth our significant financial statement items below the operating income (loss) line: Year ended December 31, (dollars in thousands) 2025 2024 Interest income $ 14,483 $ 12,124 Interest expense, net of amounts capitalized (36,977) (37,917) Equity earnings (loss) of unconsolidated affiliates 1,046 929 Other income (expense), net 2,796 3,510 Provision (benefit) for income taxes (67,861) 77,448 Interest income for the year ended December 31, 2025 as compared to 2024, increased primarily due to higher average interest-earning cash balances in 2025. In addition to interest on borrowings, interest expense includes amortization of loan costs and debt discount, and fees for lender commitments under our senior secured revolving credit agreement and standby letters of credit and bank guarantees that banks issue on our behalf for performance bonds, bid bonds and self-insurance requirements. Interest expense was relatively flat in the year ended December 31, 2025 as compared to 2024. We recorded capitalized interest of $0.4 million beginning in 2025 related to the planned implementation of our new ERP system. Foreign currency transaction gains and losses are a component of other income (expense), net. In the year ended December 31, 2025 and 2024, we incurred foreign currency transaction gains (losses) of $2.8 million and $0.9 million, respectively. These gains (losses) primarily resulted from foreign currency fluctuations in multiple countries. We could incur further foreign currency exchange gains (losses) in countries where we operate due to foreign currency exchange fluctuations. Our tax provision is based on (1) our earnings for the period and other factors affecting the tax provision and (2) the operations of foreign branches and subsidiaries that are subject to local income and withholding taxes. Factors that affect our tax rate include our profitability levels in general and the geographical mix of our results. The effective tax rate for the twelve- month periods ended December 31, 2025 and 2024 was different than the U.S. federal statutory rate of 21%, primarily due to the geographical mix of revenue and earnings, changes in valuation allowances and uncertain tax positions, and other discrete items. We continue to make an assertion to indefinitely reinvest the unrepatriated earnings of any foreign subsidiary that would incur material tax consequences upon the distribution of such earnings. We establish valuation allowances for deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized in the future. Based on the available positive and negative evidence, including a trend of positive earnings, realization of deferred tax assets, projections of future taxable income in the U.S. and several non-U.S. jurisdictions, and the absence of objective negative evidence such as a three-year cumulative loss, we believe it is more likely than not that some of our deferred tax assets in the U.S. and several non-U.S. jurisdictions will be realized. Accordingly, during the twelve-month periods ended December 31, 2025 and 2024, we released valuation allowances for the deferred tax assets that we believe are more likely than not to be realized. In accordance with applicable accounting standards, the valuation allowance decreased by $154 million in 2025 and $23 million in 2024. The 2025 decrease in valuation allowance was primarily related to US federal and state valuation allowance release of $140 million and $10 million, respectively. The 2024 decrease in valuation allowance was primarily related to valuation release in several non-US jurisdictions. As of December 31, 2025, we continue to recognize a valuation allowance on certain identified deferred tax assets in the U.S. and non-U.S. jurisdictions where we believe that it is not more-likely-than-not that we would be able to realize the benefits of those specific deferred tax assets. In the U.S., a valuation allowance of $35 million was maintained against the deferred tax assets for U.S. federal foreign tax credit carryovers with a limited carryforward 39

Table of Contents/ period. In several non-US jurisdictions, a valuation allowance of $451 million was maintained against deferred tax assets that the Company continues to believe are not more-likely-than-not to be realized. We will continue to monitor the need for a valuation allowance against its deferred tax assets and record adjustments as appropriate in future periods. Our income tax payments for the full year of 2026 are estimated to be in the range of $95 million to $105 million, which includes taxes incurred in countries that impose tax on the basis of in-country revenue, without regard to the profitability of such operations. Liquidity and Capital Resources We consider our liquidity and capital resources adequate to support our operations, capital commitments and strategic growth initiatives as well as any opportunistic returns of capital to shareholders. Our material cash commitments consist primarily of obligations for long-term debt, purchase obligations as part of normal operations, and operating leases for land, buildings, vessels and equipment for the support and operation of our business. Our purchase obligations include agreements to purchase goods and services as well as commitments for capital assets used in the normal operations of our business. We are committed to maintaining strong liquidity and believe that our cash position, undrawn Revolving Credit Agreement (as defined below), and long-term debt maturity profile provide us with ample resources and time to address our liquidity needs, including potential future growth opportunities and working capital needs. As of December 31, 2025, we had net working capital of $751 million, including cash and cash equivalents of $689 million. Additionally, as of December 31, 2025, we had $215 million of unused commitments through our Revolving Credit Agreement, which is further described below and in Note 8—“Debt” in the Notes to Consolidated Financial Statements included in this report. Availability under the $215 million revolving credit facility (the “Revolving Credit Facility”) may be limited by certain financial covenants and the requirement that any borrowing under the Revolving Credit Facility not require the granting of any liens to secure any senior notes issued by us. The indenture governing the 2028 Senior Notes (defined below) generally limits our ability to incur secured debt for borrowed money (such as borrowings under the Revolving Credit Facility) to 15% of our Consolidated Net Tangible Assets (as defined in such indentures). Our nearest maturity of indebtedness is $500 million of our 2028 Senior Notes (defined below). As of December 31, 2025, we had $411 million of purchase obligations including $383 million payable within the next twelve months and $28 million thereafter. For more on our operating leases for land, buildings, vessels and equipment for the operation of our business and their scheduled maturities, see Note 4—”Leases” in the Notes to Consolidated Financial Statements included in this report. From time to time, we may engage in certain transactions in order to manage our outstanding debt prior to maturity, including repurchases via open-market or privately negotiated transactions, redemptions, exchanges, tender offers or otherwise. See “—Financing Activities” and Note 8—“Debt” in the Notes to Consolidated Financial Statements included in this report for additional information. We can provide no assurances as to the timing of any future repurchases or whether we will complete any repurchases at all. Changes impacting our cash and cash equivalents for the years ended December 31, 2025 and 2024 are summarized as follows: Year ended December 31, (in thousands) 2025 2024 Changes in Cash: Net Cash Provided by Operating Activities $ 318,861 $ 203,214 Net Cash Used in Investing Activities (96,233) (124,171) Net Cash Used in Financing Activities (45,551) (27,042) Effect of exchange rates on cash 14,281 (16,051) Net Increase (Decrease) in Cash and Cash Equivalents$ 191,358 $ 35,950 40

Table of Contents/ Operating activities. Our primary sources and uses of cash from operating activities for the years ended December 31, 2025 and 2024 are as follows: Year ended December 31, (in thousands) 2025 2024 Cash Flows from Operating Activities: Net income (loss) $ 353,761 $ 147,468 Noncash adjustments: Depreciation and amortization 102,255 103,443 Deferred income tax provision (benefit) (140,603) (11,293) Inventory write-downs 15,430 — Other noncash 11,800 14,584 Total noncash adjustments (11,118) 106,734 Accounts receivable and contract assets 53,869 (8,000) Inventory 5,824 (13,092) Current liabilities (32,173) 8,663 Other changes (51,302) (38,559) Net Cash Provided by Operating Activities $ 318,861 $ 203,214 Net cash provided by operating activities for the years ended December 31, 2025 and 2024 of $319 million and $203 million, respectively, was affected by the following: • Accounts receivable and contract assets - The increase (decrease) in cash related to accounts receivable and contract assets in 2025 and 2024 reflects the timing of project milestones and customer payments. • Inventory - The increase (decrease) in cash related to inventory in 2025 and 2024 corresponds with a decrease in our Manufactured Products backlog in 2025 and an increase in our Manufactured Products backlog in 2024. • Current liabilities - The decrease in cash related to current liabilities in 2025 reflects the timing of vendor payments and decreased contract liabilities due to a decrease in deferred customer prepayments. The increase in cash related to current liabilities in 2024 reflects the timing of vendor payments and increased contract liabilities due to an increase in deferred customer prepayments. Investing activities. In 2025, we used $96 million in net investing activities, primarily for capital expenditures of $111 million that included increased spending in our Subsea Robotics and OPG segments to add capabilities and maintain current operations, partially offset by $8.9 million in proceeds from disposition of property and equipment. In 2024, we used $124 million in net investing activities, primarily for capital expenditures of $107 million that included increased spending in our OPG segment to add capabilities and maintain current operations. An additional $27 million was incurred for the acquisition of Global Design Innovation Ltd. (“GDi”), a U.K.-based provider of digital and software services, and $7.0 million was incurred for purchase of Angolan bonds, partially offset by $12 million in proceeds from sale of equity investments. Our capital expenditures during 2025 and 2024 included $65 million and $64 million, respectively, in our Subsea Robotics segment, principally for upgrades to our ROV fleet and to replace certain units we retired. We currently plan to add new ROVs only to meet contractual commitments. In 2025, we retired sixteen of our conventional work-class ROV systems and replaced them with sixteen upgraded conventional work-class ROV systems. Our ROV fleet size was 250 as of December 31, 2025 and 2024. In 2026, we expect our organic capital expenditures to total between $105 million and $115 million, exclusive of business acquisitions, as compared to $111 million of organic capital expenditures in 2025. We expect to fund the 2026 capital expenditures using our available cash. We remain committed to maintaining strong liquidity and believe that our cash position, undrawn revolving credit facility, and debt maturity profile should provide us with ample resources and time to address potential future growth opportunities and to improve our returns. 41

Table of Contents/ Financing activities. In 2025 we used $46 million of cash in financing activities primarily due to the repurchase of 1.8 million shares of our common stock for approximately $40 million, along with $5.3 million for payment of tax withholding related to vesting of stock awards. In 2024 we used $27 million of cash in financing activities primarily due to the repurchase of 0.8 million shares of our common stock for approximately $20 million, along with $6.9 million for payment of tax withholding related to vesting of stock awards. 2028 Senior Notes. In February 2018, we completed the public offering of $300 million aggregate principal amount of 6.000% Senior Notes due 2028 (the “Existing 2028 Senior Notes”) and on October 2, 2023, we completed a private placement of $200 million aggregate principal amount of additional 2028 Senior Notes (the “New 2028 Senior Notes” and, together with the Existing 2028 Senior Notes, the “2028 Senior Notes”). The New 2028 Senior Notes constituted an additional issuance of the Existing 2028 Senior Notes and form a single series with such notes. We pay interest on the 2028 Senior Notes on February 1 and August 1 of each year. The 2028 Senior Notes are scheduled to mature on February 1, 2028. We may redeem some or all of the 2028 Senior Notes at specified redemption prices. We received net proceeds from the offering of the New 2028 Senior Notes of $178 million, after deducting the initial purchasers’ discounts and offering expenses. As of December 31, 2025, there was $500 million of the 2028 Senior Notes outstanding. On October 2, 2023, we used the net proceeds from the offering discussed above, together with cash on hand, to fund our offer to purchase (the “Tender Offer”) for cash any and all of the $400 million principal amount outstanding of the 4.650% Senior Notes due 2024 (the “2024 Senior Notes”). We repurchased $312 million principal amount of the 2024 Senior Notes at par plus accrued and unpaid interest of $5.5 million for approximately $318 million. The consummation of the Tender Offer was contingent upon the completion of the offering discussed above, which was satisfied on October 2, 2023. We redeemed all of the remaining $88 million principal amount outstanding of the 2024 Senior Notes at par on November 2, 2023, the (“Redemption Date”), and financed the redemption with cash on hand. Revolving Credit Agreement. On April 8, 2022, we entered into a new senior secured revolving credit agreement with a group of banks (as amended by an Agreement and Amendment No. 1 to Credit Agreement, dated September 20, 2023, the “Revolving Credit Agreement”). The commitments under the Revolving Credit Agreement are scheduled to mature on April 8, 2027. The Revolving Credit Agreement includes a $215 million revolving credit facility (the “Revolving Credit Facility”), with a $100 million sublimit for the issuance of letters of credit. Our obligations under the Revolving Credit Agreement are guaranteed by certain of our wholly owned subsidiaries and are secured by first priority liens on certain of our assets and those of the guarantors, including, among other things, intellectual property, inventory, accounts receivable, equipment and equity interests in subsidiaries. As of December 31, 2025, we had no borrowings outstanding under the Revolving Credit Facility and no letters of credit outstanding under the Revolving Credit Agreement. We may borrow under the Revolving Credit Facility at either (1) a base rate, determined as the greatest of (A) the prime rate of Wells Fargo Bank, National Association, (B) the federal funds effective rate plus ⁄ of 1% and (C) Adjusted Term Secured Overnight Financing Rate (“SOFR”) (as defined in the Revolving Credit Agreement for a one-month tenor plus 1%, in each case plus the applicable margin, which varies from 1.25% to 2.25% depending on our Consolidated Net Leverage Ratio (as defined in the Revolving Credit Agreement), or (2) Adjusted Term SOFR plus the applicable margin, which varies from 2.25% to 3.25% depending on our Consolidated Net Leverage Ratio. We will also pay a facility fee based on the amount of the underlying commitment that is being utilized, which fee varies from 0.300% to 0.375%, with the higher rate owed when we use the Revolving Credit Facility less. The Revolving Credit Agreement includes financial covenants that are tested on a quarterly basis, based on the rolling four- quarter period that ends on the last day of each fiscal quarter. The maximum permitted Consolidated Net Leverage Ratio is initially 4.00 to 1.00 and subsequently decreased to 3.25 to 1.00. As of December 31, 2025 and 2024, the maximum permitted Consolidated Net Leverage Ratio was 3.25 to 1.00 and will not change during the remaining term of the Revolving Credit Facility. The minimum Consolidated Interest Coverage Ratio (as defined in the Revolving Credit Agreement) is 3.00 to 1.00 throughout the term of the Revolving Credit Facility. Availability under the Revolving Credit Facility may be limited by these financial covenants and the requirement that any borrowing under the Revolving Credit Facility not require the granting of any liens to secure any senior notes issued by us. The indentures governing the 2028 Senior Notes generally limit our ability to incur secured debt for borrowed money (such as borrowings under the Revolving Credit Facility) to 15% of our Consolidated Net Tangible Assets (as defined in such indentures). As of December 31, 2025, the full $215 million was available to borrow under the 12 42
Page 45
Table of Contents/ Revolving Credit Facility. In addition, the Revolving Credit Agreement contains various covenants that we believe are customary for agreements of this nature, including, but not limited to, restrictions on our ability and the ability of each of our subsidiaries to incur debt, grant liens, make certain investments, make distributions, merge or consolidate, sell assets and enter into certain restrictive agreements. As of December 31, 2025, we were in compliance with all of the financial covenants set forth in the Revolving Credit Agreement. Debt Issuance Costs. Discounts and Interest. We incurred $6.9 million of issuance costs related to the 2024 Senior Notes. These costs were included as a reduction of long-term debt in our consolidated balance sheet. We were amortizing these costs to interest expense through the maturity date. In the year ended December 31, 2023, we amortized $1.3 million to interest expense, including $0.7 million, for the write-off of the debt issuance costs balance associated with the retirement of the 2024 Senior Notes discussed above. We incurred $7.1 million of issuance costs related to the 2028 Senior Notes and $4.0 million of loan costs related to the Revolving Credit Agreement. These costs, net of accumulated amortization, are included as a reduction of long-term debt in our consolidated balance sheets, as they pertain to the 2028 Senior Notes, and in other noncurrent assets as they pertain to the Revolving Credit Agreement. We are amortizing these costs to interest expense through the respective maturity dates for the 2028 Senior Notes and the Revolving Credit Agreement using the straight-line method, which approximates the effective interest rate method. As a result, we amortized $2.1 million for the years ended December 31, 2025 and 2024. We recorded a discount of $20 million related to the 2028 Senior Notes issued in October 2023. This cost, net of accumulated amortization, is included as a reduction of long-term debt in our consolidated balance sheets and is being amortized to interest expense through the maturity date of the 2028 Senior Notes using the straight-line method, which approximates the effective interest rate method. In the years ended December 31, 2025 and 2024, we amortized $4.3 million and $4.0 million, respectively, to interest expense. We have not guaranteed any debt not reflected on our consolidated balance sheets as of December 31, 2025 and 2024, and we do not have any off-balance sheet arrangements, as such term is defined by the SEC rules. Share Repurchase Program. In December 2014, our Board of Directors approved a share repurchase program under which we may repurchase up to 10 million shares of our common stock on a discretionary basis. The program calls for any repurchases to be made in the open market, or in privately negotiated transactions from time to time, in compliance with applicable laws, rules and regulations, including Rule 10b-18 under the Securities Exchange Act of 1934, as amended, subject to market and business conditions, levels of available liquidity, cash requirements for other purposes, applicable legal requirements and other relevant factors. Under this program, which has no expiration date, we repurchased 2.0 shares of our common stock for approximately $100 million in 2015. We did not repurchase any shares from January 2016 through August 2024. In the year ended December 31, 2024, we repurchased 0.8 million shares for approximately $20 million. In the year ended December 31, 2025, we repurchased 1.8 million shares for approximately $40 million. From the inception of this program through December 31, 2025, we have repurchased approximately 4.6 million shares of our common stock for a total cost of approximately $161 million. As of December 31, 2025, we retained 11 million of the shares we had repurchased through this and a prior repurchase program. We account for the shares we hold in treasury under the cost method, at average cost. The timing and amount of any future repurchases will be determined by our management. We expect that any additional shares repurchased under the plan will be held as treasury stock for possible future use. The plan does not obligate us to repurchase any particular number of shares. Foreign Currency Adjustments. Because of our significant foreign operations, we are exposed to currency fluctuations and exchange rate risks. A stronger U.S. dollar against any of the foreign currencies where we conduct business could result in lower operating income. We generally minimize these risks primarily through matching, to the extent possible, revenue and expense in the various currencies in which we operate. Cumulative translation adjustments as of December 31, 2025 relate primarily to our net investments in, including long-term loans to, our foreign subsidiaries. See Item 7A—“Quantitative and Qualitative Disclosures About Market Risk.” Critical Accounting Policies and Estimates We have based the following discussion and analysis of our financial condition and results of operations on our consolidated financial statements, which we have prepared in conformity with accounting principles generally accepted in the United States. These principles require us to make various estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the periods we present. We base our estimates on historical experience, available information and other assumptions we believe to be reasonable under the circumstances. On an ongoing 43
Page 46
Table of Contents/ basis, we evaluate our estimates; however, our actual results may differ from these estimates under different assumptions or conditions. The following discussion summarizes the accounting policies we believe (1) require our management's most difficult, subjective or complex judgments and (2) are the most critical to our reporting of results of operations and financial position. See Note 1—“Summary of Significant Accounting Policies” in the Notes To Consolidated Financial Statements included in this report for discussion of our significant accounting policies. Revenue Recognition. We account for significant fixed-price contracts, mainly relating to our Manufactured Products segment, and to a lesser extent in our OPG and ADTech segments, by recognizing revenue over time using the cost-to-cost input method to measure progress toward satisfaction of an overtime performance obligation. This commonly used method is based on the premise that costs incurred are proportionate to progress towards satisfaction of the performance obligation and is measured by comparing project costs-to-date to total estimated costs. The performance obligation is satisfied as we create a product on behalf of the customer over the life of the contract. We apply judgment in estimating project status and the costs necessary to complete projects. For the year ended December 31, 2025, we recognized approximately 17% of our revenue over time using the cost-to-cost input method. While our contracts predominantly only contain one performance obligation and a limited number have variable consideration, we apply judgment, when applicable, in the determination and allocation of transaction price to performance obligations and the subsequent recognition of revenue, based on the facts and circumstances of each contract. We routinely review estimates related to our contracts and, where required, reflect revisions to profitability in earnings immediately. If an element of variable consideration has the potential for a significant future reversal of revenue, we will constrain that variable consideration to a level intended to remove the potential future reversal. If a current estimate of total contract cost indicates an ultimate loss on a contract, we recognize the projected loss in full when we determine it. We did not have any material adjustments during the years ended December 31, 2025 and 2024, however, should our judgments and estimates regarding the elements of revenue recognition change, it could have a material effect on our results of operations for the periods involved. Impairment of Property and Equipment, Long-lived Intangible Assets and Right-of-Use Operating Lease Assets. We periodically, and upon the occurrence of a triggering event, review the realizability of our property and equipment, long-lived intangible assets and right-of-use operating lease assets to determine whether any events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. For long-lived assets to be held and used, we base our evaluation on impairment indicators such as the nature of the assets, the future economic benefits of the assets, any historical or future profitability measurements and other external market conditions or factors that may be present. If such impairment indicators are present or other factors exist that indicate that the carrying amount of an asset may not be recoverable, we determine whether an impairment has occurred through the use of an undiscounted cash flows analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the fair value of the asset. Our estimates of fair values for our asset groups require us to use significant unobservable inputs, classified as Level 3 fair value measurements, including assumptions related to future performance, risk-adjusted discount rates, future commodity prices and demand for our services and estimates of expected realizable value. These assumptions incorporate inherent uncertainties, including estimates of projected supply and demand for our products and services and future market conditions, which are subjective and difficult to predict due to volatility in overall economic environments, among other things, and could result in impairment charges in future periods if actual results differ materially from the assumptions used in our forecasts. Also, if market conditions deteriorate significantly, we could be required to record additional impairments, which could have a material adverse impact on our operating results. We did not identify any triggering events and, accordingly, no impairments of long-lived assets were recorded in the years ended December 31, 2025 or 2024. Income Taxes. Our tax provisions are based on our expected taxable income, statutory rates and tax-planning opportunities available to us in the various jurisdictions in which we operate. The determination of taxable income in any jurisdiction requires the interpretation of the related tax laws. We are at risk that a taxing authority's final determination of our tax liabilities may differ from our interpretation. We account for any applicable interest and penalties on uncertain tax positions as a component of our provision for income taxes on our financial statements. Current income tax expense represents either nonresident withholding taxes or the liabilities expected to be reflected on our income tax returns for the current year, while the net deferred 44
Page 47
Table of Contents/ income tax expense or benefit generally represents the change in the balance of deferred tax assets or liabilities, except for currency translation adjustments, as reported on our balance sheet. We establish valuation allowances to reduce deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized in the future. Changes to valuation allowances based on available positive and negative evidence impact our income tax provision in the period in which such adjustments are identified and recorded. Contractual Obligations As of December 31, 2025, we had payments due under contractual obligations as follows: (dollars in thousands) Payments due by period Total 2026 2027-2028 2029-2030 After 2030 Long-term Debt $ 500,000 $ — $ 500,000 $ — $ — Purchase Obligations 410,533 383,349 18,186 2,067 6,931 Operating Lease Liabilities 453,078 145,945 141,632 58,356 107,145 Other Long-term Obligations reflected onour Balance Sheet under U.S. GAAP 42,369 149 361 387 41,472 TOTAL $ 1,405,980 $ 529,443 $ 660,179 $ 60,810 $ 155,548 45

Table of Contents/ Item 7A. Quantitative and Qualitative Disclosures About Market Risk. We are exposed to certain market risks arising from transactions we enter into in the normal course of business. These risks relate to interest rate changes and fluctuations in foreign exchange rates. As of December 31, 2025, we do not believe these risks are material to our earnings. However, with the expansion of our international operations, we could be exposed to additional market risks from fluctuations in foreign currency exchange rates in the future. We have not entered into any market-risk-sensitive instruments for speculative or trading purposes. When we have a significant amount of borrowings, we may manage our exposure to interest rate changes through the use of a combination of fixed- and floating-rate debt. See Note 8—“Debt” in the Notes to Consolidated Financial Statements included in this report for a description of our revolving credit agreement and interest rates on our borrowings. We believe significant interest rate changes would not have a material near-term impact on our future earnings or cash flows. Because we operate in various regions in the world, we conduct a portion of our business in currencies other than the U.S. dollar. The functional currency for most of our international operations is the applicable local currency. A stronger or weaker U.S. dollar against the Brazilian real, Norwegian kroner and U.K. pound sterling could impact our operating income. We manage our exposure to changes in foreign exchange rates by primarily denominating our contracts and providing for collections from our customers in U.S. dollars or freely convertible currency and endeavoring to match our contract costs with the denominated contractual currency. We use the exchange rates in effect as of the balance sheet date to translate assets and liabilities when the functional currency is the local currency, resulting in translation adjustments that we reflect as accumulated other comprehensive income or loss in the equity section of our consolidated balance sheets. We recorded net adjustments to our equity accounts of $33 million, $(47) million and $3.9 million in 2025, 2024 and 2023, respectively. Negative adjustments reflect the net impact of the strengthening of the U.S. dollar against various foreign currencies for locations where the functional currency is not the U.S. dollar. Conversely, positive adjustments reflect the effect of a weakening U.S. dollar. Foreign currency gains (losses) in the year ended December 31, 2025, 2024 and 2023 were $2.8 million, $0.9 million and $(1.4) million, respectively. We recorded foreign currency transaction gains (losses) as a component of other income (expense), net in our consolidated statements of operations in those respective periods. To mitigate our currency exposure risk in Angola, we have used kwanza to purchase Angolan central bank (Banco Nacional de Angola) bonds. The bonds are denominated in U.S. dollars, so that, upon payment of semi-annual interest and principal upon maturity, payment will be settled and made in U.S. dollars. In the third quarter of 2024, we purchased $7.0 million of U.S. dollar equivalent Angolan bonds. These bonds mature in February 2031. Because we intend to sell the bonds if we are able to repatriate the proceeds, we have classified these bonds as available-for-sale securities, and they are recorded at fair market value in other current assets in our consolidated balance sheet as of December 31, 2025 and 2024. We did not sell any of our Angolan bonds in the years ended December 31, 2025 and 2024. We estimated the fair market value of the Angolan bonds to be $7.0 million as of December 31, 2025 and 2024, using quoted market prices. Since the market for the Angolan bonds was not an active market, the fair value of the Angolan bonds was classified within Level 2 in the fair value hierarchy under accounting principles generally accepted in the United States (“U.S. GAAP”).

Disclosure Controls and Procedures In accordance with Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we carried out an evaluation, under the supervision and with the participation of management, including our principal executive officer and principal financial officer, of the effectiveness of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2025 to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange 46

Internal Control Over Financial Reporting There has been no change in our internal control over financial reporting that occurred during the quarter ended December 31, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. Management's Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as that term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control over financial reporting is a process designed to provide reasonable, but not absolute, assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with accounting principles generally accepted in the United States of America. We developed our internal control over financial reporting through a process in which our management applied its judgment in assessing the costs and benefits of various controls and procedures, which, by their nature, can provide only reasonable assurance regarding the control objectives. You should note that the design of any system of controls is based in part on various assumptions about the likelihood of future events, and we cannot assure you that any system of controls will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. 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 and procedures may deteriorate. Under the supervision and with the participation of our management, including our principal executive, financial and accounting officers, we have conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). This evaluation included a review of the documentation surrounding our financial reporting controls, an evaluation of the design effectiveness of these controls, testing of the operating effectiveness of these controls and an evaluation of our overall control environment. Based on that evaluation, our management has concluded that our internal control over financial reporting was effective as of December 31, 2025. Ernst & Young LLP, the independent registered public accounting firm that audited our financial statements, has audited our internal control over financial reporting, as stated in their report that follows. 47

Table of Contents/ Report of Independent Registered Public Accounting Firm To the Shareholders and the Board of Directors of Oceaneering International, Inc. Opinion on Internal Control Over Financial Reporting We have audited Oceaneering International, Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Oceaneering International, Inc. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income (loss), equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and our report dated February 20, 2026 expressed an unqualified opinion thereon. 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 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. /s/ Ernst & Young LLP Houston, Texas February 20, 2026 48

Table of Contents/ REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and the Board of Directors of Oceaneering International, Inc. Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Oceaneering International, Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income (loss), equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles. 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, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 20, 2026 expressed an unqualified opinion thereon. 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 Matter The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates. 56

Table of Contents/ Revenues recognized over-time utilizing cost to cost inputs Description of the Matter For the year ended December 31, 2025, the Company recognized 17% of its revenues utilizing the cost-to-cost input method. As discussed in Note 3 of the financial statements, the Company generally recognizes this type of contract revenue based on costs incurred to date as a percentage of total estimated costs. Auditing management’s calculation of revenues recognized under the cost-to-cost method was complex and subjective due to the estimation required in determining the estimated costs remaining on the project. In particular, the estimates of remaining costs associated with materials are sensitive and may be impacted by factors outside of the Company’s control. How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s process for revenues utilizing the cost-to-cost input method, including management’s review of the estimated costs to complete and associated revenues. To test the estimated costs to complete, we performed audit procedures that included, among others, assessing the appropriate application of the revenue recognition method utilized, and testing the significant assumptions discussed above and the underlying data used by the Company in its estimation process. We compared the significant assumptions used by management to external and internal information, such as vendor quotes and invoices, manufacturing schedules, purchase orders, manufacturing bills of lading, and other similar support. Additionally, we assessed the historical accuracy of management’s estimates through a lookback analysis of prior estimates of costs to complete compared to actual results. /s/ Ernst & Young LLP We have served as the Company’s auditor since 2002.

Table of Contents/ NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation. The consolidated financial statements include the accounts of Oceaneering International, Inc. (“Oceaneering,” “we,” “us” or “our”) and our 50% or more owned and controlled subsidiaries. We also consolidate entities that are determined to be variable interest entities if we determine that we are the primary beneficiary; otherwise, we account for those entities using the equity method of accounting. We use the equity method to account for our investments in unconsolidated affiliated companies where our equity ownership interest ranges from 20% to 50% and we exercise significant influence without control over operations. We use the cost method for all other long-term investments. Investments in entities that we do not consolidate are presented in other noncurrent assets on our balance sheet. All significant intercompany accounts and transactions have been eliminated. Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires that our management make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Reclassifications. Certain amounts from prior periods have been reclassified to conform with the current year presentation. Cash and Cash Equivalents. Cash and cash equivalents include demand deposits and highly liquid investments with original maturities of three months or less from the date of investment. Allowance for Credit Losses—Financial Assets Measured at Amortized Costs. We identify our allowance for credit losses based on future expected losses when accounts receivable, contract assets or held-to-maturity loan receivables are created rather than when losses are probable. We use the loss-rate method in developing the allowance for credit losses, which involves identifying pools of assets with similar risk characteristics, reviewing historical losses within the last three years and consideration of reasonable supportable forecasts of economic indicators. Changes in estimates, developing trends and other new information could have material effects on future evaluations. We monitor the credit quality of our accounts receivable and other financing receivable amounts by frequent customer interaction, following economic and industry trends and reviewing specific customer data. Our other receivable amounts include contract assets and held-to-maturity loans receivable, which we consider to have a low risk of loss. We consider macroeconomic conditions when assessing our credit risk exposure, including any impacts from the conflicts in Russia and Ukraine and in the Middle East, volatility in the financial services industry and the oil and natural gas markets, U.S. economic and monetary policies, and the effects thereof on our customers and various counterparties. We have determined the impacts to our credit loss expense are de minimis for the years ended December 31, 2025, 2024 and 2023. As of December 31, 2025, our allowance for credit losses was $1.6 million for accounts receivable and $0.5 million for other receivables. As of December 31, 2024, our allowance for credit losses was $1.5 million for accounts receivable and $1.4 million for other receivables. Our allowance for credit losses as of December 31, 2025 decreased when compared to the balance as of December 31, 2024, primarily due to a corresponding decrease in contract assets partially offset by a slight increase in accounts receivable. Financial assets are written off when deemed uncollectible and there is no reasonable expectation of recovering the contractual cash flows. During the years ended December 31, 2025, 2024 and 2023, we recognized credit losses of less than $0.1 million, $0.1 million and $1.3 million, respectively. We have elected to apply the practical expedient available under Accounting Standard Update (“ASU”) No. 2016-13, “Financial Instruments—Credit Losses (Topic 326: Measurement of Credit Losses on Financial Instruments,” as amended (“ ASC 326”) to exclude the accrued interest receivable balance that is included in our held-to-maturity loans receivable. The amounts excluded as of December 31, 2025 and 2024 were less than $0.1 million. 63
Page 67
Table of Contents/ Accounts receivable are considered to be past-due after the end of the contractual terms agreed to with the customer. There were no material past-due amounts that we consider uncollectible for our financial assets as of December 31, 2025. We generally do not require collateral from our customers. Inventory. Inventory is valued at the lower of cost or net realizable value. We determine cost using the weighted-average method. We periodically review the value of items in inventory and record write-downs or write-offs of inventory based on our assessment of market conditions. Write-downs and write-offs are charged to cost of services and products. In the year ended December 31, 2025, we recorded increases to our inventory reserve of $12 million related primarily to $13 million in write- downs associated with our theme park ride business in our Manufactured Products segment and $2.6 million related to write- downs of inventory deemed to be obsolete in our OPG and Manufactured Products segments. We did not record any write- downs or write-offs of inventory in the years ended December 31, 2024 or 2023. Our inventory reserve was $48 million and $36 million as of December 31, 2025 and 2024, respectively. Business Acquisitions. We account for business combinations using the acquisition method of accounting, with acquisition prices being allocated to the assets acquired and liabilities assumed based on their fair values at the respective dates of acquisition. In October 2024, we acquired Global Design Innovation Ltd. (“GDi”), a United Kingdom (“U.K.”)-based provider of digital and software services, for approximately $33 million, including a holdback liability of $4.6 million that we recorded in accrued liabilities and other long-term liabilities on our consolidated balance sheets. As of December 31, 2025, the remaining holdback liability was $3.7 million recorded in accrued liabilities on our consolidated balance sheets, and we expect to make the final payment of this balance in 2026. We acquired cash of $1.0 million from GDi as part of this acquisition. GDi is a U.K.-based provider of asset management, engineering and software services. As the only provider certified by the U.K. Accreditation Service to perform remote visual inspection using point cloud data and photographic images, GDi brings advanced algorithms and data solutions that, when combined with Oceaneering’s engineering expertise, will strengthen Oceaneering’s ability to optimize asset management for customers in industries including oil and gas, utilities, and power generation. GDi’s suite of solutions, including its Vision software, complements Oceaneering’s portfolio by supporting enhanced safety, data quality and integrity, and cost efficiency for customers worldwide. We accounted for this acquisition by allocating the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. As part of this acquisition, we recorded goodwill for $16 million and intangible assets relating primarily to GDi’s software and trade name for $17 million to be amortized over their useful lives of 5 years. GDi’s operating results are included in our IMDS segment, and its activity subsequent to the date of acquisition was not significant. Property and Equipment, Long-Lived Intangible Assets and Right-of-Use Operating Lease Assets. We depreciate property and equipment using the straight-line method over estimated useful lives. Remotely Operated Vehicles (“ROVs”) are depreciated over eight years, marine services equipment (such as vessels) over three to 25 years and buildings improvements, manufacturing equipment and other equipment for three to 25 years. We charge the costs of repair and maintenance of property and equipment to operations as incurred, and we capitalize the costs of improvements that extend asset lives or functionality. Upon the disposition of property and equipment, the related cost and accumulated depreciation accounts are relieved and any resulting gain or loss is recognized in income. We capitalize interest on assets where the construction period is anticipated to be more than three months. We do not allocate general administrative costs to capital projects. We did not capitalize interest in 2025, 2024 or 2023 related to construction of assets. We had construction in progress of $67 million and $60 million as of December 31, 2025 and 2024, respectively, primarily related to projects in our Subsea Robotics and OPG segment. Long-lived intangible assets, primarily acquired in connection with business combinations, include trade names, intellectual property and customer relationships and are being amortized over their respective estimated useful lives. Our management periodically, and upon the occurrence of a triggering event, reviews the realizability of our property and equipment, long-lived intangible assets and right-of-use operating lease assets to determine whether any events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable. For long-lived assets to be held and used, we base our evaluation on impairment indicators such as the nature of the assets, the future economic benefits of the assets, any historical or future profitability measurements and other external market conditions or factors that may be present. If such impairment indicators are present or other factors exist that indicate that the carrying amount of an asset may not be recoverable, we determine whether an 64
Page 68
Table of Contents/ impairment has occurred using an undiscounted cash flow analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the fair value of the asset. We did not identify indicators of impairment for property and equipment, long-lived intangible assets or right-of-use operating lease assets for the years ended December 31, 2025, 2024 and 2023. For assets held for sale or disposal, the fair value of the asset is measured using fair market value less estimated costs to sell. Assets are classified as held-for-sale when we have a plan for disposal of certain assets and those assets meet the held for sale criteria. For additional information regarding right-of-use operating lease assets, see “Leases” below. Cloud-Based Service Contract Costs. We capitalized certain implementation costs related to a service-only cloud computing arrangement in the year ended December 31, 2025. Capitalized costs are included on our consolidated balance sheets in other noncurrent assets and will be amortized to selling, general and administrative expense on a straight-line basis over the contract term. In the year ended December 31, 2025, we capitalized $17 million of deferred software implementation costs related to cloud computing arrangements, including $0.4 million, respectively, of interest. We did not capitalize any cloud-based service contract costs in the year ended December 31, 2024 or 2023. Goodwill. Our goodwill is evaluated for impairment annually and whenever we identify certain triggering events or circumstances that would more likely than not reduce the fair value of a reporting unit below its carrying amount. In our annual evaluation of goodwill, we perform a qualitative or quantitative impairment test. Under the qualitative approach, if we determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we are required to perform the quantitative analysis to determine the fair value of the reporting unit. We then compare the fair value of the reporting unit with its carrying amount and recognize an impairment loss for the amount by which the carrying amount exceeds the fair value of the reporting unit. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. We also consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. During the fourth quarters of 2025 and 2024, we performed our annual goodwill impairment assessment using qualitative tests that did not indicate a more detailed quantitative analysis was necessary. No goodwill impairment was recognized for the years ended December 31, 2025, 2024 and 2023. Revenue Recognition. All of our revenue is realized through contracts with customers. We recognize our revenue according to the contract type. On a daily basis, we recognize service revenue over time for contracts that provide for specific time, material and equipment charges, which we bill periodically. We use the input method to recognize revenue, because each day of service provided represents value to the customer. The performance obligations in these contracts are satisfied, and revenue is recognized, as the work is performed. When appropriate, we apply the practical expedient to recognize revenue for the amount invoiced when the invoice corresponds directly to the value of our performance to date. We account for significant fixed-price contracts, primarily within our Manufactured Products segment, and to a lesser extent in our Offshore Projects Group (“OPG”) and Aerospace and Defense Technologies (“ADTech”) segments, by recognizing revenue over time using the cost-to-cost input method. The performance obligation is satisfied as we create a product on behalf of the customer over the life of the contract. In 2025, 2024 and 2023, we accounted for 17%, 19% and 19%, respectively, of our revenue using the cost-to-cost input method to measure progress toward satisfying the related performance obligations on our contracts. The remainder of our revenue is recognized at the point in time when control transfers to the customer, thus satisfying the performance obligation. We have elected to recognize the cost for freight and shipping as an expense when incurred. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, and that are collected by us from customers, are excluded from revenue. In our service-based business lines, we principally charge on a dayrate basis for services provided. In our product-based business lines, predominantly in our Manufactured Products segment, we recognize revenue and profit using the percentage- of-completion method and exclude uninstalled materials and significant inefficiencies from the measure of progress. While our contracts predominantly only contain one performance obligation and a limited number have variable consideration, we apply judgment, when applicable, in the determination and allocation of transaction price to 65
Page 69
Table of Contents/ performance obligations and the subsequent recognition of revenue, based on the facts and circumstances of each contract. We routinely review estimates related to our contracts and, when required, reflect revisions to profitability in earnings immediately. If an element of variable consideration has the potential for a significant future reversal of revenue, we will constrain that variable consideration to a level intended to remove the potential future reversal. If a current estimate of total contract cost indicates an ultimate loss on a contract, we recognize the projected loss in full when we determine it. During the year ended December 31, 2025, we recognized a projected loss of $4.3 million for contracts in our Manufactured Products segment. During the year ended December 31, 2024, we recognized a projected loss of $13 million for contracts in our Manufactured Products segment. During the year ended December 31, 2023, we recognized a projected loss of $9.8 million for contracts in our Manufactured Products segment. There could be adjustments to overall contract costs in the future, due to changes in facts and circumstances. In general, our payment terms consist of those services billed regularly as provided and those products delivered at a point in time, which are invoiced after the performance obligation is satisfied. Our product and service contracts with milestone payments due at agreed progress points during the contract are invoiced when those milestones are reached, which may differ from the timing of revenue recognition. Our payment terms generally do not provide financing of contracts to customers, nor do we receive financing from customers as a result of these terms. See Note 3—“Revenue” for more information on our revenue from contracts with customers. Leases. We determine whether a contract is or contains a lease at inception, whether as a lessee or a lessor. We take into consideration the elements of an identified asset, right to control and the receipt of economic benefit in making those determinations. As a lessor, we lease certain types of equipment along with the provision of services and utilize the expedient allowing us to combine the lease and non-lease components into a combined component that is accounted for (1) under the accounting standard “Leases” (“ASC 842”), when the lease component is predominant, and (2) under the accounting standard “Revenue from Contracts with Customers” (“ASC 606”), when the service component is predominant. In general, when we have a service component, it is typically the predominant element and leads to accounting under ASC 606. As a lessor, we lease certain types of equipment, often providing services at the same time. These leases can be priced on a dayrate or lump-sum basis for periods ranging from a few days to multi-year contracts. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our customer's discretion. These leases generally do not contain options to purchase, material restrictions or covenants that impact our accounting for leases. As a lessee, we lease land, buildings, vessels and equipment for the operation of our business and to support some of our service line revenue streams. These generally carry lease terms that range from days for operational and support equipment up to twenty years for land and buildings. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our discretion. When the exercise of those options is reasonably certain, we include them in the lease assessment. Our leases do not contain material restrictions or covenants that impact our accounting for them, nor do we provide residual value guarantees. As a lessee, we utilize the practical expedients to not recognize leases with an initial lease term of 12 months or less on the balance sheet and to combine lease and non-lease components together and account for the combined component as a lease for all asset classes, except real estate. Right-of-use operating lease assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement or modification date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate, based on the information available at commencement or modification date in determining the present value of future payments. In determining the incremental borrowing rate, we considered our external credit ratings, bond yields for us and our identified peers, the risk-free rate in geographic regions where we operate and the impact associated with providing collateral over a similar term as the lease for an amount equal to the future lease payments. Our right-of-use operating lease assets also include any lease prepayments made and exclude lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease. These options are included in the lease term when it is reasonably certain we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. See Note 4—“Leases” for more information on our operating leases. 66

Table of Contents/ Stock-Based Compensation. We recognize all share-based payments to directors, officers and employees over their vesting periods in the income statement based on their estimated fair values. For more information on our employee benefit plans, see Note 11—“Employee Benefit Plans.” Income Taxes. We provide income taxes at appropriate tax rates in accordance with our interpretation of the respective tax laws and regulations after review and consultation with our internal tax department, tax advisors and, in some cases, legal counsel in various jurisdictions. We provide for deferred income taxes for differences between carrying amounts of assets and liabilities for financial and tax reporting purposes and provide a valuation allowance against deferred tax assets when it is more likely than not that the asset will not be realized. We recognize an expense or benefit for an uncertain tax position if it is more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the uncertain tax position is then measured and recognized at the largest amount that we believe is greater than 50% likely of being realized upon ultimate settlement. We account for any applicable interest and penalties on these uncertain tax positions as a component of our provision for income taxes on our financial statements. We have elected to account for U.S. federal income tax on global intangible low ‑ taxed income (“GILTI”) as a current period expense when incurred. For more information on income taxes, see Note 6—“Income Taxes.” Foreign Currency Translation. The functional currency for most of our foreign subsidiaries is the applicable local currency. Results of operations for foreign subsidiaries with functional currencies other than the U.S. dollar are translated into U.S. dollars using average exchange rates during the period. Assets and liabilities of these foreign subsidiaries are translated into U.S. dollars using the exchange rates in effect as of the balance sheet date, and the resulting translation adjustments are recognized, net of tax, in accumulated other comprehensive income (loss) as a component of shareholders' equity. All foreign currency transaction gains and losses are recognized currently in the consolidated statements of operations. We recorded $2.8 million, $0.9 million and $(1.4) million of foreign currency transaction gains (losses) in the years ended December 31, 2025, 2024 and 2023, respectively. Those amounts are included as a component of other income (expense), net in our consolidated statements of operations. Earnings (Loss) per Share. For each year presented, the only difference between our annual calculated weighted-average basic and diluted number of shares outstanding is the effect of outstanding restricted stock units. Share Repurchase Plan. In December 2014, our Board of Directors approved a plan to repurchase up to 10 million shares of our common stock on a discretionary basis. Under the program, which has no expiration date, we had repurchased 2.0 million shares for approximately $100 million through December 2015. In the year ended December 31, 2024, we repurchased 0.8 million shares for approximately $20 million. In the year ended December 31, 2025, we repurchased 1.8 million shares for approximately $40 million. As of December 31, 2025, there were approximately 5.4 million shares remaining available for repurchase under this plan and we retained approximately eleven million of the shares we had repurchased through this and a prior repurchase program. We expect to hold the shares repurchased and any additional shares repurchased under the plan as treasury stock for possible future use. The timing and amount of any future repurchases will be determined by our management. We are not obligated to make any future repurchases. We account for the shares we hold in treasury under the cost method, at average cost. Financial Instruments. We recognize all derivative instruments as either assets or liabilities in the balance sheet and measure those instruments at fair value. Subsequent changes in fair value are reflected in current earnings or other comprehensive income (loss), depending on whether a derivative instrument is designated as part of a hedge relationship and, if it is, the type of hedge relationship. See Note 8—“Debt” for information relative to the interest rate swaps we had in effect. We currently have no derivative instruments outstanding as of December 31, 2025 or 2024. Consolidated Variable Interest Entity. We hold a 45% interest in one variable interest entity (“VIE”) located in Angola. The remaining 55% noncontrolling interest is held by a service and logistics provider located in Angola. We are the primary beneficiary and wholly consolidate the VIE as we have the power to direct the activities that most significantly affect the VIE’s economic performance and have the obligation to absorb the VIE’s losses and the right to receive benefits at 100%. 67

Table of Contents/ 2. ACCOUNTING STANDARDS UPDATE Recently Adopted Accounting Standards. In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“Topic 740”), which applies to all entities subject to income taxes. Topic 740 requires disaggregated information about a reporting entity’s effective tax rate reconciliation, including percentages and amounts, as well as information on income taxes paid, net of refunds disaggregated by federal, state, local and foreign and by jurisdiction if the amount is 5% or more of total income tax payments, net of refunds. Topic 740 is effective for annual periods beginning after December 15, 2024. We adopted ASU 2023-09 prospectively, effective for the year ended December 31, 2025. For more information on this adoption, see Note 6—“Income Taxes.” Recently Issued Accounting Standards. In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses” (“ASU 2024-03”), which requires additional disclosure of the nature of certain expenses presented on the face of the income statement into specified categories in the footnotes to the financial statements. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. We anticipate that ASU 2024-03 will only impact our disclosures and therefore do not expect that ASU 2024-03 will have a material impact on our consolidated financial statements. 3. REVENUE Revenue by Category The following table presents revenue disaggregated by business segment, geographical region, and timing of transfer of goods or services. Year Ended December 31, (in thousands) 2025 2024 2023 Business Segment: Energy: Subsea Robotics $ 855,216 $ 829,822 $ 752,521 Manufactured Products 568,971 555,500 493,692 Offshore Projects Group 616,045 591,037 546,366 Integrity Management & Digital Solutions 284,020 291,866 255,282 Total Energy 2,324,252 2,268,225 2,047,861 Aerospace and Defense Technologies 459,904 392,936 376,845 Total $ 2,784,156 $ 2,661,161 $ 2,424,706 Year Ended December 31, (in thousands) 2025 2024 2023 Geographic Operating Areas: Foreign: Africa $ 417,615 $ 434,536 $ 331,891 United Kingdom 289,575 291,464 205,886 Norway 259,201 233,134 189,802 Brazil 248,064 229,534 202,892 Asia and Australia 228,445 210,582 274,160 Other 97,811 134,106 189,694 Total Foreign 1,540,711 1,533,356 1,394,325 United States 1,243,445 1,127,805 1,030,381 Total $ 2,784,156 $ 2,661,161 $ 2,424,706 68

Year Ended December 31, (in thousands) 2025 2024 2023 Timing of Transfer of Goods or Services: Revenue recognized over time $ 2,582,447 $ 2,474,830 $ 2,272,160 Revenue recognized at a point in time 201,709 186,331 152,546 Total $ 2,784,156 $ 2,661,161 $ 2,424,706 Contract Balances Our contracts with milestone payments have, in the aggregate, a significant impact on the contract asset and the contract liability balances. Milestones are contractually agreed with customers and relate to significant events across the contract lives. Some milestones are achieved before revenue is recognized, resulting in a contract liability, while other milestones are achieved after revenue is recognized resulting in a contract asset. The following table provides information about contract assets and contract liabilities from contracts with customers. Year Ended December 31, (in thousands) 2025 2024 Total contract assets, beginning of period $ 275,280 $ 234,505 Revenue accrued 2,643,062 2,540,010 Amounts billed (2,701,534) (2,499,235) Total contract assets, end of period $ 216,808 $ 275,280 Total contract liabilities, beginning of period $ 140,697 $ 164,631 Deferrals of milestone payments 111,914 109,641 Recognition of revenue for goods and services (137,578) (133,575) Total contract liabilities, end of period $ 115,033 $ 140,697 Performance Obligations As of December 31, 2025, the aggregate amount of the transaction price allocated to remaining performance obligations that were unsatisfied (or partially unsatisfied) was $396 million. In arriving at this value, we have used two expedients available to us and are not disclosing amounts in relation to performance obligations: (1) that are part of contracts with an original expected duration of one year or less; or (2) on contracts where we recognize revenue in line with the billing. Of this amount, we expect to recognize revenue of $309 million over the next 12 months, $86 million within the next 24 months, and substantially all of the remaining balance of $1.2 million within the next 36 months. In our Manufactured Products and ADTech segments, we have long-term contracts that extend beyond one year, and these make up the majority of the performance obligations balance reported as of December 31, 2025. We also have shorter-term product contracts with an expected original duration of one year or less that have been excluded. Where appropriate, we have made estimates within the transaction price of elements of variable consideration within the contracts and constrained those amounts to a level where we consider it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The amount of revenue recognized in the years ended December 31, 2025 and 2024 that was associated with performance obligations completed or partially completed in prior periods was not significant. As of December 31, 2025, there were no significant outstanding liability balances for refunds or returns due to the nature of our contracts and the services and products we provide. Our warranties are limited to assurance warranties that are of a standard length and are not considered to be material rights. The majority of our contracts consist of a single performance obligation. While our contracts predominantly only contain one performance obligation and a limited number have variable consideration, when there are multiple obligations, we look for observable evidence of stand-alone selling prices on which to base the allocation. This involves judgment as to the 69
Page 73
appropriateness of the observable evidence relating to the facts and circumstances of the contract. If we do not have observable evidence, we estimate stand-alone selling prices by taking a cost-plus-margin approach, using typical margins from the type of product or service, customer and regional geography involved. Costs to Obtain or Fulfill a Contract In line with the available practical expedient, we capitalize incremental costs to obtain a contract that would not have been incurred if the contract had not been obtained when those amounts are significant and the contract is expected at inception to exceed one year in duration. Our costs to obtain a contract primarily consist of bid and proposal costs, which are generally expensed in the period incurred. There were no balances or amortization of costs to obtain a contract in the current reporting periods. Costs to fulfill a contract primarily consist of certain mobilization costs incurred to provide services or products to our customers. These costs are deferred and amortized over the period of contract performance. The closing balance of costs to fulfill a contract was $2.1 million and $3.2 million as of December 31, 2025 and 2024, respectively. For the years ended December 31, 2025, 2024 and 2023, we recorded amortization expense of $2.9 million, $4.9 million, and $5.8 million, respectively. No impairment costs were recognized. 4. LEASES Supplemental information about our operating leases follows: December 31, (in thousands) 2025 2024 Assets: Right-of-use operating lease assets $ 349,751 $ 334,721 Liabilities: Current $ 128,453 $ 131,415 Noncurrent 257,269 238,325 Lease liabilities $ 385,722 $ 369,740 December 31, 2025 2024 Lease Term and Discount Rate: Weighted-average remaining lease term (years) 5.8 6.0 Weighted-average discount rate 6.0 % 5.9 % No impairments of right-of-use operating leases were recorded in the years ended December 31, 2025 and 2024. Operating lease cost reflects the lease expense resulting from amortization over the respective lease terms of our operating leases with initial lease terms greater than 12 months. Our short-term lease cost consists of expense for our operating leases with initial lease terms of 12 months or less that are not recorded on our balance sheet.

The carryforwards include $69 million that do not expire and $464 million that will expire from 2026 through 2045. 75
Page 79
Table of Contents We assess the realizability of our deferred tax assets, considering all relevant factors, at each reporting period. Based on the available positive and negative evidence, including a trend of positive earnings, as well as our outlook and expectations for future taxable income positively influenced by favorable macroeconomic conditions, anticipated continued growth in demand for energy-related products, improving deepwater offshore activity expected toward the end of 2026 and beyond, and continued expansion of non-energy-related businesses, we believe it is more likely than not that some of our deferred tax assets in the U.S. and several non-U.S. jurisdictions will be realized. Accordingly, during the twelve-month periods ended December 31, 2025 and 2024, we released valuation allowances for the deferred tax assets that we believe are more likely than not to be realized. Our valuation allowance decreased by $154 million in 2025 and $23 million in 2024. The 2025 decrease in valuation allowance was primarily related to US federal and state valuation allowance releases of $140 million and $10 million, respectively. The 2024 decrease in valuation allowance was primarily related to valuation releases for certain non-US jurisdictions. As of December 31, 2025, we continue to recognize a valuation allowance on certain identified deferred tax assets in the U.S. and non-U.S. jurisdictions where we believe that it is not more-likely-than-not that we would be able to realize the benefits of those specific deferred tax assets. In the U.S., a valuation allowance of approximately $35 million was maintained against the deferred tax assets for U.S. federal foreign tax credit carryovers with a limited carryforward period. In several non-US jurisdictions, a valuation allowance of approximately $451 million was maintained against deferred tax assets that the Company continues to believe are not more-likely-than-not to be realized. We will continue to monitor the need for a valuation allowance against its deferred tax assets and record adjustments as appropriate in future periods During the twelve-month period ended December 31, 2023, we received refunds of $23 million, including interest of $1.7 million which was recorded as a tax benefit, under the U.S. Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). We continue to make an assertion to indefinitely reinvest the unrepatriated earnings of any foreign subsidiary that would incur material tax consequences upon the distribution of such earnings. As of December 31, 2025, we did not provide for deferred taxes on earnings of our foreign subsidiaries that are indefinitely reinvested. If we were to make a distribution from the unremitted earnings of these subsidiaries, we could be subject to taxes in various jurisdictions. If our expectations were to change regarding future tax consequences, we may be required to record additional deferred taxes that could have a material effect on our consolidated financial statements. We recognize the expense or benefit for an uncertain tax position if it is more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the uncertain tax position is then measured and recognized at the largest amount that we believe is greater than 50% likely of being realized upon ultimate settlement. We account for any applicable interest and penalties on these positions as a component of our provision for income taxes in our consolidated financial statements. A reconciliation of the beginning and ending amount of gross uncertain tax positions, excluding penalties and interest, is as follows: Year Ended December 31, (in thousands) 2025 2024 2023 Balance at beginning of year $ 18,537 $ 25,457 $ 15,846 Additions based on tax positions related to the current year 805 1,782 4,391 Reductions for expiration of statutes of limitations (410) (505) (130) Additions based on tax positions related to prior years 517 2,790 12,576 Reductions based on tax positions related to prior years (2,812) (7,020) (135) Settlements (8,311) (3,967) (7,091) Balance at end of year $ 8,326 $ 18,537 $ 25,457 We increased (decreased) income tax expense by $(2.7) million, $1.0 million and $5.4 million in 2025, 2024 and 2023, respectively, for penalties and interest on uncertain tax positions. Our total liabilities for penalties and interest on uncertain tax positions were $2.9 million and $5.6 million in other long-term liabilities on our balance sheets as of December 31, 2025 and 2024, respectively. All additions or reductions to those liabilities would affect our effective income tax rate in the periods of change. 76

Table of Contents Our tax returns are subject to audit by taxing authorities in multiple jurisdictions. These audits often take years to complete and settle. The following table lists the earliest tax years open to examination by tax authorities where we have significant operations: Jurisdiction Periods United States 2022 United Kingdom 2023 Norway 2020 Angola 2015 Brazil 2020 Australia 2021 On July 4, 2025, President Trump signed into law the legislation commonly referred to as the One Big Beautiful Bill Act (“OBBBA”). The OBBBA includes various provisions that impact the timing and magnitude of certain tax deductions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The OBBBA has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. We have incorporated the provisions that were effective beginning in the third quarter of 2025 and assessed that the impacts did not have a material impact on our consolidated financial statements. We continue to assess any future impacts on our consolidated financial statements and will recognize the income tax effects beginning in the period in which they are effective. 7. SELECTED INCOME STATEMENT INFORMATION The following schedule shows our revenue and costs of services and products: Year Ended December 31, (in thousands) 2025 2024 2023 Revenue: Services $ 2,208,190 $ 2,098,501 $ 1,920,348 Products 575,966 562,660 504,358 Total revenue 2,784,156 2,661,161 2,424,706 Cost of Services and Products: Services 1,632,842 1,598,530 1,498,094 Products 461,202 475,860 428,686 Unallocated expenses 121,670 101,277 98,955 Total cost of services and products 2,215,714 2,175,667 2,025,735 8. DEBT The carrying value of long-term debt consisted of the following: December 31, (in thousands) 2025 2024 6.000% Senior Notes due 2028 $ 500,000 $ 500,000 Unamortized discount and debt issuance costs (12,583) (17,991) Long-term Debt $ 487,417 $ 482,009 2024 Senior Notes. In November 2014, we completed the public offering of $500 million aggregate principal amount of 4.650% Senior Notes due 2024 (the “2024 Senior Notes”). We paid interest on the 2024 Senior Notes on May 15 and November 15 of each year. The 2024 Senior Notes were scheduled to mature on November 15, 2024. In the year ended December 31, 2021, we repurchased $100 million in aggregate principal amount of the 2024 Senior Notes in open-market transactions. The aggregate purchase price in the year ended December 31, 2021 included accrued and unpaid interest to the repurchase date of $0.7 million, and we recorded loss on extinguishment of debt of $1.1 million (including premiums and fees associated with the repurchases). On October 2, 2023, we repurchased $312 million principal amount of the 2024 Senior Notes at par plus accrued and unpaid interest of $5.5 million for approximately $318 million in the Tender Offer (as defined herein). On November 2, 2023 77

Table of Contents (the “Redemption Date”), after delivering a notice to the holders of the 2024 Senior Notes, we redeemed all of the remaining $88 million principal amount outstanding of the 2024 Senior Notes at par, pursuant to our optional redemption right under the indenture governing the 2024 Senior Notes. The redemption price was equal to 100% of the principal amount of the 2024 Senior Notes plus accrued and unpaid interest up to but not including the Redemption Date plus a “make-whole premium.” 2028 Senior Notes. In February 2018, we completed the public offering of $300 million aggregate principal amount of 6.000% Senior Notes due 2028 (the “Existing 2028 Senior Notes”) and on October 2, 2023, we completed a private placement of $200 million aggregate principal amount of additional 2028 Senior Notes (the “New 2028 Senior Notes” and, together with the Existing 2028 Senior Notes, the “2028 Senior Notes”). The New 2028 Senior Notes constituted an additional issuance of the Existing 2028 Senior Notes and form a single series with such notes. We pay interest on the 2028 Senior Notes on February 1 and August 1 of each year. The 2028 Senior Notes are scheduled to mature on February 1, 2028. The indentures governing our 2028 Senior Notes generally limit our ability to incur secured debt for borrowed money (such as borrowings under our revolving credit facility) to 15% of our Consolidated Net Tangible Assets (as defined in such indentures) and contain various other covenants and events of default. We used the net proceeds from the Existing 2028 Senior Notes to repay our term loan indebtedness described further below. We may redeem some or all of the 2028 Senior Notes at specified redemption prices. We received net proceeds from the offering of the New 2028 Senior Notes of $178 million, after initial purchasers’ discounts and debt issuance costs. We used the net proceeds from the New 2028 Senior Notes, together with cash on hand, to fund the Tender Offer (as defined herein). On October 2, 2023, we used the net proceeds from the offering discussed above, together with cash on hand, to fund our offer to purchase (the “Tender Offer”) for cash any and all of the $400 million principal amount outstanding of the 2024 Senior Notes. The consummation of the Tender Offer was contingent upon the completion of the offering discussed above, which was satisfied on October 2, 2023. Revolving Credit Agreement. On April 8, 2022, we entered into a new senior secured revolving credit agreement with a group of banks (as amended by an Agreement and Amendment No. 1 to Credit Agreement, dated September 20, 2023, the “Revolving Credit Agreement”). The commitments under the Revolving Credit Agreement are scheduled to mature on April 8, 2027. The Revolving Credit Agreement includes a $215 million revolving credit facility (the “Revolving Credit Facility”) with a $100 million sublimit for the issuance of letters of credit. Our obligations under the Revolving Credit Agreement are guaranteed by certain of our wholly owned subsidiaries and are secured by first priority liens on certain of our assets and those of the guarantors, including, among other things, intellectual property, inventory, accounts receivable, equipment and equity interests in subsidiaries. As of December 31, 2025 and 2024, we had no borrowings outstanding under the Revolving Credit Facility and no letters of credit outstanding under the Revolving Credit Agreement. We may borrow under the Revolving Credit Facility at either (1) a base rate, determined as the greatest of (A) the prime rate of Wells Fargo Bank, National Association, (B) the federal funds effective rate plus ⁄ of 1% and (C) Adjusted Term Secured Overnight Financing Rate (“SOFR”) (as defined in the Revolving Credit Agreement for a one-month tenor plus 1%, in each case plus the applicable margin, which varies from 1.25% to 2.25% depending on our Consolidated Net Leverage Ratio (as defined in the Revolving Credit Agreement), or (2) Adjusted Term SOFR plus the applicable margin, which varies from 2.25% to 3.25% depending on our Consolidated Net Leverage Ratio. We will also pay a facility fee based on the amount of the underlying commitment that is being utilized, which fee varies from 0.300% to 0.375%, with the higher rate owed when we use the Revolving Credit Facility less. The Revolving Credit Agreement includes financial covenants that are tested on a quarterly basis, based on the rolling four- quarter period that ends on the last day of each fiscal quarter. The maximum permitted Consolidated Net Leverage Ratio was initially 4.00 to 1.00 and subsequently decreased to 3.25 to 1.00. As of December 31, 2025 and 2024, the maximum permitted Consolidated Net Leverage Ratio was 3.25 to 1.00 and will not change during the remaining term of the Revolving Credit Facility. The minimum Consolidated Interest Coverage Ratio (as defined in the Revolving Credit Agreement) is 3.00 to 1.00 throughout the term of the Revolving Credit Facility. Availability under the Revolving Credit Facility may be limited by these financial covenants and the requirement that any borrowing under the Revolving Credit Facility not require the granting of any liens to secure any senior notes issued by us. The indentures governing the 2028 Senior Notes, and prior to November 2, 2023, the 2024 Senior Notes, generally limit our ability to incur secured debt for borrowed money (such as borrowings under the Revolving Credit Facility) to 15% of our Consolidated Net Tangible Assets (as defined in such indentures). As of December 31, 2025, the full $215 million was available to borrow under the Revolving Credit Facility. In addition, the Revolving Credit Agreement contains various covenants that we believe are customary for agreements of this nature, including, but not limited to, restrictions on our ability and the ability of each of our subsidiaries to incur debt, grant liens, make 12 78
Page 82
Table of Contents certain investments, make distributions, merge or consolidate, sell assets and enter into certain restrictive agreements. As of December 31, 2025, we were in compliance with all of the covenants set forth in the Revolving Credit Agreement. Interest Rate Swaps. We had two interest rate swaps in place relating to a total of $200 million of the 2024 Senior Notes for the period to November 2024. The agreements swapped the fixed interest rate of 4.65% on $100 million of the 2024 Senior Notes to the floating rate of one-month London Interbank Offered Rate (“LIBOR”) plus 2.426% and on another $100 million to one-month LIBOR plus 2.823%. In March 2020, we settled both interest rate swaps with the counterparty for cash proceeds of $13 million. The settlement resulted in a $13 million increase to our long-term debt balance that was being amortized as a reduction to interest expense prospectively through the maturity date for the 2024 Senior Notes using the effective interest method. In the year ended December 31, 2023, we amortized $4.4 million to interest expense, including $2.7 million, for the write-off of interest rate swap settlement gains associated with the retirement of the 2024 Senior Notes discussed above. Debt Issuance Costs, Discount and Interest. We incurred $6.9 million of issuance costs related to the 2024 Senior Notes. These costs were included as a reduction of long-term debt in our consolidated balance sheet. We were amortizing these costs to interest expense through the maturity date. In the year ended December 31, 2023, we amortized $1.3 million to interest expense, including $0.7 million, for the write-off of the debt issuance costs balance associated with the retirement of the 2024 Senior Notes discussed above. We incurred $7.1 million of issuance costs related to the 2028 Senior Notes and $4.0 million of loan costs related to the Revolving Credit Agreement. These costs, net of accumulated amortization, are included as a reduction of long-term debt in our consolidated balance sheets, as they pertain to the 2028 Senior Notes, and in other noncurrent assets, as they pertain to the Revolving Credit Agreement. We are amortizing these costs to interest expense through the respective maturity dates for the 2028 Senior Notes and the Revolving Credit Agreement using the straight-line method, which approximates the effective interest rate method. In the years ended December 31, 2025 and 2024, we amortized $2.1 million to interest expense. We recorded a discount of $20 million related to the 2028 Senior Notes issued in October 2023. This cost, net of accumulated amortization, is included as a reduction of long-term debt in our consolidated balance sheets and is being amortized to interest expense through the maturity date of the 2028 Senior Notes using the straight-line method, which approximates the effective interest rate method. In the years ended December 31, 2025 and 2024, we amortized $4.3 million and $4.0 million, respectively, to interest expense. We made cash interest payments of $32 million, $32 million and $34 million in 2025, 2024 and 2023, respectively. 9. COMMITMENTS AND CONTINGENCIES Lease Commitments. As of December 31, 2025, we occupied several facilities under noncancellable operating leases expiring at various dates through 2040. See Note 4—“Leases” for more information on our operating leases. Insurance. The workers' compensation, maritime employer's liability and comprehensive general liability insurance policies that we purchase each include a deductible layer, for which we would be responsible, that we consider financially prudent. Insurance above the deductible layers can be by occurrence or in the aggregate. We determine the level of accruals for claims exposure by reviewing our historical experience and current year claim activity. We do not record accruals on a present-value basis. We review larger claims with insurance adjusters and establish specific reserves for known liabilities. We establish an additional reserve for incidents incurred but not reported to us for each year using our estimates and based on prior experience. We believe we have established adequate accruals for expected liabilities arising from those obligations. However, it is possible that future earnings could be affected by changes in our estimates relating to these matters. Litigation. In the ordinary course of business, we are, from time to time, involved in litigation or subject to disputes, governmental investigations or claims related to our business activities, including, among other things: • performance- or warranty-related matters under our customer and supplier contracts and other business arrangements; and • workers’ compensation claims, Jones Act claims, occupational hazard claims, premises liability claims and other claims. Although we cannot predict the ultimate outcome of these matters, we believe that our ultimate liability, if any, that may result from these other actions and claims will not have a material adverse effect on our consolidated financial 79
Page 83
Table of Contents condition, results of operations or cash flows. However, because of the inherent uncertainty of litigation and other dispute resolution proceedings and, in some cases, the availability and amount of potentially available insurance, we can provide no assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material effect on our consolidated financial condition, results of operations or cash flows for the fiscal period in which that resolution occurs. Letters of Credit. We had $77 million and $72 million in letters of credit outstanding as of December 31, 2025 and 2024, respectively, which related to self-insurance requirements and various bid and performance bonds, which are usually for the duration of the applicable contract. Financial Instruments and Risk Concentration. In the normal course of business, we manage risks associated with foreign exchange rates and interest rates through a variety of strategies, including the use of hedging transactions. As a matter of policy, we do not use derivative instruments unless we have an underlying exposure. Other financial instruments that potentially subject us to concentrations of credit risk are principally cash and cash equivalents and accounts receivable. The carrying values of cash and cash equivalents approximate their fair values due to the short-term maturity of the underlying instruments. Accounts receivable are generated from a broad group of customers, primarily from the energy industry and the U.S. Government, which are major sources of our revenue. Due to their short-term nature, carrying values of our accounts receivable and accounts payable approximate fair market values. We estimated the aggregate fair market value of the 2028 Senior Notes to be $508 million as of December 31, 2025 based on quoted prices. Since the market for the 2028 Senior Notes is not an active market, the fair value of the 2028 Senior Notes is classified within Level 2 in the fair value hierarchy under U.S. GAAP (inputs other than quoted prices in active markets for similar assets and liabilities that are observable or can be corroborated by observable market data for substantially the full terms for the assets or liabilities). Foreign currency gains (losses) were $2.8 million, $0.9 million and $(1.4) million in the years ended December 31, 2025, 2024 and 2023, respectively. We recorded foreign currency transaction gains (losses) as a component of other income (expense), net in our consolidated statements of operations in those respective periods. Any conversion of cash balances in deposit accounts in Angola from kwanza to U.S. dollars is controlled by the central bank in Angola. As of December 31, 2025 and 2024, we had the equivalent of approximately $28 million and $19 million of kwanza cash balances, respectively, in Angola reflected on our consolidated balance sheets. To mitigate our currency exposure risk in Angola, we have used kwanza to purchase Angolan central bank (Banco Nacional de Angola) bonds. These bonds are denominated in U.S. dollars, so that, upon payment of semi-annual interest and principal upon maturity, payment will be made in U.S. dollars. In the third quarter of 2024, we purchased $7.0 million of U.S. dollar equivalent Angolan bonds. These bonds mature in February 2031. Because we intend to sell the bonds if we are able to repatriate the proceeds, we have classified these bonds as available-for-sale securities, and they are recorded at fair market value in other current assets in our Consolidated Balance Sheets as of December 31, 2025 and 2024. We did not sell any of our Angolan bonds in the year ended December 31, 2025 or 2024. We estimated the fair market value of the Angolan bonds to be $7.0 million as of December 31, 2025 and 2024, using quoted market prices. Since the market for the Angolan bonds was not an active market, the fair value of the Angolan bonds was classified within Level 2 in the fair value hierarchy under U.S. GAAP. As of December 31, 2022, we had $6.2 million of U.S. dollar equivalent Angolan bonds that were classified as available-for- sale securities and recorded at fair market value in other current assets in our consolidated balance sheets. These bonds matured on September 1, 2023, and we received cash proceeds of kwanza equivalent to $6.2 million in U.S. dollars. In the three-month period ended June 30, 2021, we were notified by a customer in our Manufactured Products segment that it was suspending a contract that was substantially complete. Specific to this contract, we billed and received approximately $12 million in the years ended December 31, 2025 and 2024. As of December 31, 2025, we had outstanding contract assets of approximately $1.7 million for the contract and contract liabilities of $0.4 million prepaid for storage of components. As of December 31, 2024, we had outstanding contract assets of approximately $1.3 million for the contract and contract liabilities of $2.2 million prepaid for storage of components. During the first quarter of 2025, the customer restarted portions of this project, including the scope for our Manufactured Products segment. We continue to believe we will realize these contract assets at their book values, although we can provide no assurance as to the timing of receipt of the remaining payments. 80

Our Energy business leverages our asset base and capabilities for providing services and products for offshore energy operations, inclusive of the offshore renewables energy market. Our Energy segments are: • Subsea Robotics—Our Subsea Robotics segment provides the following: ◦ ROVs for drill support and vessel-based services, including subsea hardware installation, construction, pipeline inspection, survey and facilities inspection, maintenance and repair; ◦ ROV tooling; and ◦ survey services, including hydrographic survey and positioning services and autonomous underwater vehicles for geoscience. • Manufactured Products—Our Manufactured Products segment provides the following: ◦ distribution and connection systems including production control umbilicals and field development hardware and pipeline connection and repair systems, along with clamp connectors and subsea and topside control valves primarily to the energy industry; and ◦ autonomous mobile robotic technology to a variety of industries. • Offshore Projects Group—Our OPG segment provides the following: ◦ subsea installation and intervention, including riserless light well intervention services, inspection, maintenance and repair (“IMR”) services, principally in the U.S. Gulf and offshore Africa, utilizing owned and charter vessels; ◦ installation and workover control systems and ROV workover control systems; ◦ diving services; ◦ project management and engineering; and ◦ drill pipe riser services and systems and wellhead load relief solutions. • Integrity Management & Digital Solutions—Our Integrity Management & Digital Solutions (“IMDS”) segment provides the following: ◦ asset integrity management services; and ◦ ◦ software, digital and connectivity solutions for the energy industry. Our Aerospace and Defense Technologies segment provides services and products, including engineering and related manufacturing in defense and space exploration activities, principally to U.S. Government agencies and their prime contractors. Unallocated Expenses are those not associated with a specific business segment. These consist of expenses related to our incentive and deferred compensation plans, including restricted stock units, performance units and bonuses, as well as other general expenses, including corporate administrative expenses. Our chief operating decision maker (“CODM”) is our chief executive officer. Our CODM analyzes each segment’s performance using revenue and operating income (loss). Operating income (loss) for each business segment includes certain regional shared services cost allocations directly attributable to each segment. Intersegment revenue and expenses have been eliminated in the reported revenue and operating income (loss). We determine operating income (loss) for each business segment before interest income or expense, equity in income (losses) of unconsolidated affiliates, other income (expense) and provision for income taxes. Our CODM uses both revenue and operating income (loss) for each segment in the annual budgeting and forecasting processes. The CODM considers budget-to-actual and forecast-to-actual variances on a quarterly basis when making decisions about the allocation of operating and capital resources to each segment. 81

Table of Contents Revenue. For the year ended December 31, 2025, revenue from one customer, the U.S. Government, which is served primarily by our ADTech segment, accounted for 12% of our total consolidated annual revenue, and no other customer accounted for more than 10% of our total consolidated revenue. No individual customer accounted for more than 10% of our consolidated revenue for the year ended December 31, 2024. For the year ended December 31, 2023, revenue from one customer, the U.S. Government, which is served primarily by our ADTech segment, accounted for 10% of our total consolidated annual revenue, and no other customer accounted for more than 10% of our total consolidated revenue. Depreciation and Amortization Expense. Depreciation expense on property and equipment, reflected in the Depreciation and Amortization Expense table above, was $86 million, $89 million and $99 million in 2025, 2024 and 2023, respectively. Amortization expense primarily relating to long-lived intangible assets and debt issuance costs and discounts, reflected in the Depreciation and Amortization Expense table above, was $16 million, $14 million and $6.4 million 2025, 2024 and 2023, respectively. Assets, Property and Equipment, Net and Goodwill. All assets specifically identified with a particular business segment have been segregated. Cash and cash equivalents, certain other current assets, certain investments and certain other assets have not been allocated to particular business segments and are included in Corporate and Other. The changes in our reporting units’ goodwill balances are from the acquisition of GDi in the fourth quarter of 2024 and currency exchange rate changes for all of the periods presented. Geographic Operating Areas. For 2025 and 2024, $350 million and $335 million, respectively, of right-of-use operating lease assets are included in the following table which summarizes Property and Equipment, Net and Right-of-Use Operating Lease Assets by geographic area: December 31, (in thousands) 2025 2024 Property and Equipment, Net and Right-of-Use Operating Lease Assets Foreign: Brazil $ 89,564 $ 72,449 United Kingdom 85,389 77,584 Norway 79,949 74,754 Africa 67,523 87,354 Asia and Australia 45,221 36,197 Other 9,231 10,982 Total Foreign 376,877 359,320 United States 424,567 395,499 Total $ 801,444 $ 754,819 Revenue is based on location where services are performed and products are manufactured. See Note 3—”Revenue” for disclosure of revenue by geographic area . 11. EMPLOYEE BENEFIT PLANS Retirement Investment Plans. We have several employee retirement investment plans that, taken together, cover most of our full-time employees. The Oceaneering Retirement Investment Plan is a 401(k) plan in which U.S. employees may participate by deferring a portion of their gross monthly salary and directing us to contribute the deferred amount to the plan. We match a portion of the employees' deferred compensation. Our contributions to the 401(k) plan were $26 million, $24 million and $23 million for the plan years ended December 31, 2025, 2024 and 2023, respectively. We also make matching contributions to foreign employee savings plans similar in nature to a 401(k) plan. In 2025, 2024 and 2023, these contributions, principally related to plans associated with the U.K. and Norwegian subsidiaries, were $16 million, $14 million and $12 million, respectively. 86
Page 90
The Oceaneering International, Inc. Supplemental Executive Retirement Plan covers selected key management employees and executives, as approved by the Compensation Committee of our Board of Directors (the “Compensation Committee”). Under this plan, we accrue an amount determined as a percentage of the participant's gross monthly salary and the amounts accrued are treated as if they are invested in one or more investment vehicles pursuant to this plan. Net expenses related to this plan during 2025, 2024 and 2023 were $3.2 million, $1.9 million and $1.3 million, respectively. Incentive Plans. Under our Second Amended and Restated 2010 Incentive Plan and our 2020 Incentive Plan (together the “Incentive Plans”), shares of our common stock are made available for awards to employees and nonemployee members of our Board of Directors. The Incentive Plans are administered primarily by the Compensation Committee; however, the full Board of Directors makes determinations regarding awards to nonemployee directors under the Incentive Plans. The Compensation Committee or our Board of Directors, as applicable, determines the type(s) of award(s) to be made to each participant and sets forth in the related award agreement the terms, conditions and limitations applicable to each award. Stock options, stock appreciation rights and stock and cash awards may be made under the Incentive Plans. There are no options outstanding under either Incentive Plan. We have not granted any stock options since 2005 and the Compensation Committee has expressed its intention to refrain from using stock options as a component of employee compensation for our executive officers and other employees for the foreseeable future. Additionally, the Board of Directors has expressed its intention to refrain from using stock options as a component of nonemployee director compensation for the foreseeable future. In 2025, 2024 and 2023, the Compensation Committee granted awards of performance units to certain of our key executives and employees. The performance units awarded are scheduled to vest in full on the third anniversary of the applicable award dates, or pro rata over three years if the participant meets certain age and years of service requirements. The Compensation Committee and the Board of Directors approved specific financial goals and measures (as defined), for each of the three-year periods ending December 31, 2027, 2026 and 2025 to be used as the basis for the final value of the performance units. The final value of the performance unit granted may range from $0 to $200 in each of 2025, 2024 and 2023. Upon vesting and determination of value, the value of the performance units will be payable in cash. Compensation expense related to the performance units was $12 million, $10 million and $12 million in 2025, 2024 and 2023, respectively. As of December 31, 2025, there were 264,767 performance units outstanding. Annually, the Compensation Committee of our Board of Directors grants restricted units of our common stock to certain of our key executives and employees and restricted common stock to our nonemployee directors. Over 80%, 78% and 80% of the grants made to our employees in 2025, 2024 and 2023, respectively, vest in full on the third anniversary of the award date, conditional upon continued employment through such vesting date. The remainder of the grants made to employees are scheduled to vest pro rata over three years, if the participant meets certain age and years-of-service requirements. For the grants of restricted stock units to each of the participant employees, the participant will be issued one share of our common stock for each of the participant's vested restricted stock units at the earlier of three years or, if the participant vested earlier after meeting the age and service requirements, following termination of employment or service; however, the restricted stock units outstanding have no voting or dividend rights. The grants of restricted stock to our nonemployee directors generally vest in full on the first anniversary of the award date, conditional upon continued service as a director, except for the 2023 grant to one director who retired from our board of directors as of the date of our annual meeting in May 2023, which vested on that date. Each grantee of shares of restricted stock to our nonemployee directors is deemed to be the record owner of those shares during the restriction period, with the right to vote and receive any dividends on those shares. The Compensation Committee has a policy that Oceaneering will not provide U.S. federal income tax gross-up payments to any of its directors or executive officers in connection with future awards of restricted stock or stock units. The additional tax charge(benefit) realized from tax deductions less than or in excess of the financial statement expense of our restricted stock grants was $(1.1) million, $(2.0) million and $(1.4) million in 2025, 2024 and 2023, respectively. The 2025, 2024 and 2023 charges were recognized in our consolidated statements of operations. 87

The grants in 2025, 2024 and 2023 were subject only to vesting conditioned on continued employment or service as a nonemployee director; therefore, these grants were valued at the grant date fair market value using the closing price of our stock on the New York Stock Exchange. Compensation expense under the restricted stock plans was $13 million, $12 million and $11 million for 2025, 2024 and 2023, respectively. As of December 31, 2025, we had $12 million of future expense to be recognized related to our restricted stock unit plans over a weighted-average remaining life of 1.6 years. Post-Employment Benefit. Pursuant to a service agreement we entered into with a former Chairman of the Board of Directors, we are obligated to provide for medical coverage on an after-tax basis to him, his spouse and two adult children for their lives. Our total accrued liabilities, current and long-term, under this post-employment benefit were $1.8 million as of both December 31, 2025 and 2024. 88

Exhibit 4.01 Description of Securities Registered Pursuant to Section 12 of the Securities Exchange Act of 1934 Oceaneering International, Inc., a Delaware corporation (“Oceaneering,” “we,” “our” or “us”), has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”): common stock, par value $0.25 per share (our “common stock”). The following contains a description of our common stock, as well as certain related additional information. This description is a summary only and does not purport to be complete. We encourage you to read the complete text of Oceaneering’s restated certificate of incorporation, as amended (our “certificate of incorporation”), and amended and restated bylaws (our “bylaws”), which we have incorporated by reference as exhibits to our Annual Report on Form 10-K. References to “stockholders” refer to holders of our common stock, unless the context otherwise requires. General Under our certificate of incorporation, we have the authority to issue 363,000,000 shares of capital stock, consisting of 360,000,000 shares of our common stock and 3,000,000 shares of preferred stock, par value $1.00 per share (“preferred stock”). All of the outstanding shares of our common stock are fully paid and nonassessable. Voting Rights Our stockholders are entitled to one vote for each share of our common stock held on all matters submitted to a vote of the stockholders, including the election of directors. Holders of our common stock have no right to cumulate their votes in an election of directors. Under our bylaws, in connection with an election of directors at any meeting of our stockholders at which a quorum is present, each nominee for election is elected by the vote of a plurality of votes cast. However, our Corporate Governance Guidelines provide that, in an uncontested election of directors, any director nominee who does not receive a “for” vote by a majority of shares present in person or by proxy and entitled to vote and actually voting on the matter shall promptly tender his or her resignation to the nominating and corporate governance committee of Oceaneering’s board of directors (our “board of directors”), subject to acceptance by our board of directors. The nominating and corporate governance committee would then make a recommendation to our board of directors with respect to the director’s resignation and our board of directors would consider the recommendation and take appropriate action within 120 days from the date of the certification of the election results. Our bylaws also provide that, in the case of any question to come before any meeting of our stockholders at which a quorum is present and to which the stockholder approval policy of any national securities exchange or quotation system on which our capital stock is traded or quoted on our application, the requirements under the Exchange Act, or any provision of the Internal Revenue Code of 1986, as amended, or the rules and regulations thereunder (the “Code”), applies, in each case for which question our certificate of incorporation, our bylaws or the General Corporation Law of the State of Delaware, as amended (the “DGCL”), does not specify a higher voting requirement, that question will be decided by the requisite vote that such stockholder approval policy, Exchange Act requirement or Code provision, as the case may be, specifies (or the highest requisite vote if more than one applies). A majority of the votes cast on the question whether to approve the appointment of independent public accountants (if that question is submitted for a vote of our stockholders at any such meeting) will be sufficient to approve such appointment. All other elections and questions that have properly come before any meeting at which a quorum is present will, unless our certificate of incorporation, our bylaws or applicable law otherwise provides, be decided by the vote of the holders of shares of our capital stock present in person or by proxy at that meeting and having a majority of the votes entitled to vote on such matters. Our board of directors may grant holders of any series of preferred stock, in the resolutions creating that series of preferred stock, the right to vote on the election of directors or any questions affecting us. For additional discussion, see “Effects of Certain Provisions of our Certificate of Incorporation and Bylaws and Delaware Law – Issuance of Preferred Stock.”
Page 93
Dividend Rights Subject to the preferred rights of the holders of shares of any class or series of preferred stock, holders of our common stock are entitled to receive, out of our funds legally available therefor, such dividends (payable in cash, stock or otherwise) as our board of directors may from time to time determine, payable to stockholders of record on such record dates as shall be established by our board of directors. The declaration and amount of future dividends is at the discretion of our board of directors and will depend on, among other factors, our financial condition, results of operations, cash flows, current and anticipated expansion plans, requirements under Delaware law and other factors that our board of directors may deem relevant. In addition, the payment of dividends on our common stock may be limited by obligations we may have to holders of any preferred stock or by the provisions of our debt instruments. Liquidation Rights Our stockholders would be entitled to share ratably in our net assets upon a liquidation or dissolution, after the payment or provision for all liabilities and subject to any preferential liquidation rights of any preferred stock that at the time may be outstanding. No Preemptive, Conversion or Redemption Rights Our stockholders have no preemptive, subscription, conversion or redemption rights, and are not subject to further calls or assessments by us. There are no sinking fund provisions applicable to our common stock. Listing Our common stock is traded on the New York Stock Exchange under the symbol “OII.” Effects of Certain Provisions of Our Certificate of Incorporation and Bylaws and Delaware Law Our certificate of incorporation, our bylaws and Delaware law contain provisions that may delay, defer or prevent a change of control of Oceaneering, including pursuant to one or more proposals a stockholder might consider to be in his or her best interest, impede or lengthen a change in membership of our board of directors or make removal of our management more difficult. Action by Stockholders Without a Meeting Our bylaws provide that stockholders may take action without a meeting of stockholders only if the holders of a majority of the stock which would have been entitled to vote upon such action consent in writing to such action. The bylaw provisions require that any stockholder proponent seeking to effect an action by written consent must deliver to our corporate secretary a written notice (together with accompanying materials, in the case of the election of directors) containing substantially the same information or meeting substantially the same requirements as described below under “Advance- Notice Provisions” and request that our board of directors fix a record date for determining stockholders entitled to consent in writing to such action. If our board of directors determines that such notice and request are in proper form, our bylaws provide that the board of directors shall promptly adopt a resolution fixing the record date. No written consent will be effective to take the specified corporate action unless written consents signed by a sufficient number of stockholders of record to take such action are delivered to us within a 60-day period, beginning with the first date on which a written consent with respect to such action is delivered to us. Special Meetings of Stockholders Our bylaws provide that special meetings of stockholders may be called at any time by: • our board of directors, pursuant to a resolution to call a special meeting that a majority of the total number of our directors has duly adopted; • any committee of our board of directors that is duly designated and empowered to call special meetings; • the chairman of our board of directors; and • our chief executive officer.
Page 94
No other person or persons may call a special meeting of stockholders. The business to be transacted at any special meeting of stockholders will be confined to the purpose stated in the notice of the meeting. Advance-Notice Provisions Our bylaws contain advance-notice and other procedural requirements that apply to stockholder nominations of persons for election to the board of directors at any annual or special meeting of stockholders and to stockholder proposals that stockholders take any other action at any annual meeting. Generally, in the case of an annual meeting, stockholders must deliver to our corporate secretary a written notice between 180 and 90 days before the anniversary date of our immediately preceding annual meeting of the stockholders. In the case of an annual meeting that is more than 30 days before or more than 60 days after such anniversary date, stockholders must deliver such notice 90 days prior to such annual meeting or 10 days following the day on which public announcement of the date of such meeting is first made by us. If the chairman of our board of directors, a majority of our board of directors or our chief executive officer calls a special meeting of stockholders for the election of directors, a stockholder proposing to nominate a person for that election must give our corporate secretary written notice of the proposal not earlier than 180 days prior to that special meeting and not later than the last to occur of (1) 90 days prior to that special meeting or (2) the 10th day following the day we publicly disclose the date of the special meeting. In no event will the adjournment of a meeting of stockholders, or postponement or recess of a meeting of stockholders for which notice was given, or the public announcement of such adjournment, postponement or recess, commence a new time period for any stockholder to give notice. To be in proper form, the notice must include, among other things, (1) the name and address of the stockholder, certain information regarding the shares owned by the stockholder or any “associate” (generally defined to mean any person with whom the stockholder has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting or disposing of any of our capital stock), (2) a description of any agreement, arrangement or understanding relating to any hedging or certain other transactions that have been entered into or made by the stockholder or any associate of the stockholder, (3) a description of specified types of agreements, arrangements or understandings between the stockholder or any associate of the stockholder and each proposed nominee of the stockholder (in the case of nominations for election of directors) or any other person (in the case of other business proposed to be brought before the meeting), including any agreements, arrangements or understandings relating to acquiring, holding or voting shares, or changing or influencing control of Oceaneering, (4) a list of all transactions by the stockholder or any associate of the stockholder involving any of our securities or any of the hedging or other transactions referred to above within the six-month period immediately prior to the date of the notice, (5) certain representations made by the stockholder (including, among other things, a representation that the stockholder or a qualified representative of the stockholder intends to appear in person at that meeting to bring that other business or nomination before that meeting and a representation that the stockholder is a holder of record of capital stock entitled to vote at the meeting and will continue to be a holder of record of capital stock entitled to vote at the meeting through the date of the meeting (and, with regard to nomination notices, an additional representation as to whether such person intends to (a) deliver a proxy statement to holders representing at least 67% of the voting power of the shares of capital stock of the Company entitled to vote thereon, (b) otherwise solicit proxies or votes in support of the nomination or (c) engage in a solicitation with respect to such nomination, and if so, the name of each participant in such solicitation)) and (6) all other information, if any, relating to the stockholder or any associate of the stockholder that would be required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act. To nominate one or more directors, the notice must also include, as to each person whom the stockholder proposes to nominate for election as a director, the name, age, and business and residence addresses of such person, the principal occupation or employment of such person, certain information regarding the shares owned by the stockholder and all other information, if any, relating to such person that would be required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act. Any such notice relating to one or more director nominations must be accompanied by the following documents (which we will provide in standard form upon request), each completed and signed by the nominee(s): (1) a questionnaire (with respect to the background and qualifications of such person) and (2) a representation and agreement (with respect to (a) certain voting commitments, (b) agreements as to compensation, reimbursement or indemnification in connection with service or action as a director, (c) compliance with applicable law and applicable stock exchange rules, the applicable provisions of our bylaws and certain of our policies and guidelines and (d) the intention, if elected as a director, to serve the full term for which such person is elected. Additionally, the notice must include such other information about the stockholder, each proposal and nominee as required by the Securities and Exchange Commission. Our
Page 95
bylaws also require notification from a stockholder proponent if any of the information provided in its business proposal or nomination notice changes, within a specified time period prior to the meeting of stockholders. Director nominations and stockholder proposals that are late or that do not include all required information may be rejected. Additionally, if any stockholder that provided a nomination notice subsequently notifies us that they no longer intend to comply with (or fails to provide in the required time period reasonable evidence of compliance with) certain requirements of Exchange Act Rule 14a-19(a), then we may disregard any proxies or votes solicited for such proposed nominees. The advance-notice provisions may have the effect of precluding a contest for the election of directors or the consideration of stockholder proposals if the proper procedures are not followed, and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors or to approve its own proposal. Classified Board of Directors Our certificate of incorporation and bylaws provide for a classified board of directors. Except for directors that the holders of preferred stock may elect, our board of directors is divided into three classes, with the directors of each class as nearly equal in number as possible. The directors of each class serve a term that expires at the third succeeding annual meeting of our stockholders after their election, and each director holds office until his or her successor is duly elected and qualified. At each annual meeting of our stockholders, the term of a different class of our directors expires. Our certificate of incorporation also provides that: • the classified board provisions may not be amended without the affirmative vote of the holders of at least 80% of the outstanding shares of our common stock; • no decrease in the number of our directors will shorten the term of any incumbent director; and • a director may be removed only for cause. As described below under “Vacancies on our Board of Directors,” our certificate of incorporation also provides generally that any vacancies will be filled only by the affirmative vote of a majority of our remaining directors, even if less than a quorum. Therefore, without an amendment to our certificate of incorporation, our board of directors could prevent any stockholder from enlarging our board of directors and filling the new directorships with that stockholder's own nominees. The classification of our board of directors could prevent a party who acquires control of a majority of our outstanding “voting stock” (defined to include all outstanding shares of capital stock of Oceaneering or another corporation entitled to vote generally in the election of directors) from obtaining control of our board of directors until the second annual stockholders' meeting following the date that party obtains that control. Vacancies on our Board of Directors Our bylaws provide that, subject to the rights of the holders of any outstanding series of preferred stock and unless otherwise required by law or resolution of our board of directors, newly created vacancies on the board of directors arising through death, resignation or removal, an increase in the number of directors or otherwise may be filled by a majority of the directors then in office, even if less than a quorum. Business Combination Transactions Requiring More Than a Majority Vote. Under our certificate of incorporation, the holders of at least 80% of the voting power of the then outstanding shares of our capital stock who are eligible to vote generally in the election of directors are required to approve some types of business transactions between Oceaneering and a “related person” (defined to include any person or entity that, together with its affiliates and associates, beneficially owns 20% or more of our outstanding voting stock), including: • any merger or consolidation of Oceaneering or any of our subsidiaries with a related person; • any sale, lease, exchange, mortgage, transfer or other disposition of assets, including voting securities of our subsidiaries, representing more than 30% of the fair market value of our total assets to a related person;
Page 96
• specified types of asset acquisitions, including acquisitions of securities of a related person, from a related person; and • the issuance by us or any of our subsidiaries of any of our securities or securities of any of our subsidiaries to a related person. The same level of stockholder approval is also required for: • the adoption of any plan or proposal for our liquidation or dissolution if, as of the record date for the determination of stockholders entitled to vote on that plan or proposal, any person is a related person; • any recapitalization that would have the effect of increasing the voting power of a related person; and • any amendment of these super-majority approval requirements. The continuing directors, as defined in our certificate of incorporation, may waive the provisions described above by special vote approving the business combination transaction. In addition, these provisions will not apply if specific fair price requirements are met. The super-majority requirements described above could cause the following: • a delay, deferral or prevention of a change in control of our company; • entrench management; or • make it more difficult to effect a business transaction even if the transaction is favored by a majority of our independent stockholders. Delaware Business Combination Statute We are a Delaware corporation and are subject to Section 203 of the DGCL (“Section 203”). Section 203 prohibits a “business combination” between a corporation and an “interested stockholder” within three years of the time the stockholder became an interested stockholder, unless: • prior to such time, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder; • upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, exclusive of shares owned by directors who are also officers and by certain employee stock plans; or • at or subsequent to such time, the business combination is approved by the board of directors and authorized at a stockholders’ meeting by at least two ‑ thirds of the outstanding voting stock that is not owned by the interested stockholder. Under Section 203, the restrictions described above also do not apply to specific business combinations proposed by an interested stockholder following the announcement or notification of designated extraordinary transactions involving the corporation and a person who had not been an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation's directors, if a majority of the directors who were directors prior to any person's becoming an interested stockholder during the previous three years, or were recommended for election or elected to succeed those directors by a majority of those directors, approve or do not oppose that extraordinary transaction. Generally under Section 203: (1) a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder; and (2) an “interested stockholder” is a person who owns 15% or more of the corporation’s outstanding voting stock, together with the affiliates or associates of such person.
Page 97
Issuance of Preferred Stock Our certificate of incorporation authorizes up to 3,000,000 shares of preferred stock. Preferred stock may, by resolution, from time to time, be issued in one or more series as may be determined by our board of directors, and the board of directors, without further approval of the stockholders, is authorized to fix by resolution or resolutions providing for the classification, liquidation and dividend rights, voting rights, conversion or exchange rights, and any other rights, restrictions and qualifications of and the terms of any redemption and liquidation preferences and any purchase, retirement or sinking fund which may be provided for such shares of preferred stock, to the fullest extent permitted by applicable law. The issuance of shares of preferred stock may adversely affect the rights of the holders of our common stock. For example, any preferred stock issued may rank prior to our common stock as to dividend rights, liquidation preference or both, may have full or limited voting rights and may be convertible into shares of common stock. As a result, the issuance of shares of preferred stock may discourage bids for shares of our common stock or may otherwise adversely affect the market price of our common stock. Furthermore, undesignated preferred stock may enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a tender offer, proxy contest, merger or otherwise, and to thereby protect the continuity of our management. Limitations on Directors’ Liability Delaware law authorizes Delaware corporations to limit or eliminate the personal liability of their directors to them and their stockholders for monetary damages for breach of a director's fiduciary duty of care. The duty of care requires that, when acting on behalf of the corporation, directors must exercise an informed business judgment based on all material information reasonably available to them. Absent the limitations Delaware law authorizes, directors of Delaware corporations are accountable to those corporations and their stockholders for monetary damages for conduct constituting gross negligence in the exercise of their duty of care. Delaware law enables Delaware corporations to limit available relief to equitable remedies such as injunction or rescission. Our certificate of incorporation limits the liability of our directors to us or our stockholders to the fullest extent Delaware law permits. Specifically, no member of our board of directors will be personally liable for monetary damages for any breach of the member's fiduciary duty as a director, except for liability: • for any breach of the member's duty of loyalty to us or our stockholders; • for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; • for unlawful payments of dividends or unlawful stock repurchases or redemptions or provided in Section 174 of the DGCL; and • for any transaction from which the member derived an improper personal benefit. This provision could have the effect of reducing the likelihood of derivative litigation against our directors and may discourage or deter our stockholders or management from bringing a lawsuit against our directors for breach of their duty of care, even though such an action, if successful, might otherwise have benefited our stockholders and us. Our bylaws provide indemnification to our officers and directors and other specified persons with respect to their conduct in various capacities, and we have entered into agreements with each of our directors and officers which indemnify them to the fullest extent Delaware law permits.

g. “Effective Date” means October 2, 2023. h. “Erroneously Awarded Compensation” means the Compensation Eligible for Recovery less the amount of such compensation as it would have been determined based on the restated amounts, computed without regard to any taxes paid. i. “Exchange Act” means the Securities Exchange Act of 1934, as amended. j. “Executive Officer” means the Company’s principal executive officer, principal financial officer, principal accounting officer (or if there is no such accounting officer, the controller), any vice-president of the Company in charge of a principal business unit, division, or function (such as sales, administration or finance) and any other officer who performs a significant policy-making function, and any other person who performs similar policy-making functions for the Company. For purposes of this policy, Executive Officers would include, at a minimum, executive officers identified pursuant to 17 C.F.R. 229.401(b). k. “Financial Reporting Measure” means measures that are determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measures that are derived wholly or in part from such measures. Stock price and total shareholder return are considered Financial Reporting Measures. For the avoidance of doubt, a Financial Reporting Measure need not be presented within the financial statements or included in a filing with the Commission. l. “Incentive-based Compensation” means any compensation that is granted, earned, or vested based wholly or in part upon the attainment of a Financial Reporting Measure. m.“NYSE” means the New York Stock Exchange LLC. n. “Policy” means this Policy for the Recovery of Erroneously Awarded Compensation, as the same may be amended or amended and restated from time to time. o. “Recovery Period” means the three completed fiscal years immediately preceding the Restatement Date and any transition period (that results from a change in the Company’s fiscal year) of less than nine months within or immediately following those three completed fiscal years. p. “Restatement” means an accounting restatement: i. due to material noncompliance of the Company with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or 2
Page 106
ii. that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. q. “Restatement Date” means the earlier of: i. the date the Audit Committee concludes, or reasonably should have concluded, that the Company is required to prepare a Restatement, or ii. the date a court, regulator, or other legally authorized body directs the Company to prepare a Restatement. 4. Recovery of Erroneously Awarded Compensation. a. The Chief Financial Officer or Chief Accounting Officer of the Company shall promptly report to the Audit Committee any instance in which the Company is required to prepare a Restatement. b. Upon learning of a required Restatement, the Audit Committee shall determine the Restatement Date and shall promptly report to the Compensation Committee such determination. c. The Chief Financial Officer or Chief Accounting Officer (or another appropriate officer or third party designated by the Compensation Committee) shall promptly (but in any event within ninety (90) days following the Restatement) calculate the Erroneously Awarded Compensation for each affected individual, which calculation shall be subject to Compensation Committee approval. For purposes of calculating Erroneously Awarded Compensation: i. Incentive-based Compensation shall be deemed received in the Company’s fiscal period during which the Financial Reporting Measure specified in the Incentive-based Compensation award is attained, even if the payment or grant of the Incentive-based Compensation occurs after the end of that period. ii. Incentive-based Compensation based on (or derived from) stock price or total shareholder return, where the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in a Restatement, shall be based on a reasonable estimate of the effect of the Restatement on the stock price or total shareholder return upon which the Incentive-based Compensation was received. The Company shall maintain documentation of the determination of such reasonable estimate and provide such documentation to the NYSE. 3
Page 107
d. Promptly following the Compensation Committee’s approval of the Erroneously Awarded Compensation calculated by the Chief Financial Officer or Chief Accounting Officer (or another appropriate officer or third party designated by the Compensation Committee), the Company shall notify in writing each individual who received Erroneously Awarded Compensation of the amount of Erroneously Awarded Compensation received by such individual and shall demand payment or return, as applicable, of such Erroneously Award Compensation. e. The Company shall demand recovery and recover Erroneously Awarded Compensation in compliance with this Policy except to the extent that the Compensation Committee determines that (I) recovery of the Erroneously Awarded Compensation would be duplicative of compensation recovered by the Company from the individual pursuant to Section 304 of the Sarbanes-Oxley Act or pursuant to other recovery obligations (in which case, the amount of Erroneously Awarded Compensation shall be appropriately reduced to avoid such duplication), or (II) recovery would be impracticable, and one of the following conditions applies: i. the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be recovered. Before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation based on expense of enforcement, the Company must make a reasonable attempt to recover such Erroneously Awarded Compensation, document such reasonable attempt(s) to recover, and provide that documentation to the NYSE; ii. recovery would violate home country law where that law was adopted prior to November 28, 2022. Before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation based on violation of home country law, the Company must obtain an opinion of home country counsel, acceptable to the NYSE, that recovery would result in such a violation, and must provide such opinion to the NYSE; or iii.recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder. f. Except as provided in Section 4(e), in no event may the Company accept repayment from the affected individual of less than the full amount of the Erroneously Awarded Compensation received by such individual. g. The Compensation Committee shall determine, in its sole discretion, the method of recovering any Erroneously Awarded Compensation pursuant to this Policy, taking into account all facts and circumstances (including the time value of 4
Page 108
money and the cost to shareholders of delayed recovery), so long as such method complies with the terms of Section 303A.14 of the NYSE Listing Standards. If the Compensation Committee determines that an appropriate method of recovery is one other than the prompt repayment by the affected individual in cash or property, the Company may offer to enter into a repayment agreement with the affected individual (in a form and with terms reasonably acceptable to the Compensation Committee). h. If the affected individual fails to repay to the Company when due the full amount of the Erroneously Awarded Compensation received by such affected individual, the Company shall take all actions reasonable and appropriate to recover the full amount of the Erroneously Awarded Compensation from the affected individual. 5. Disclosure. The Company shall file all disclosures with respect to this Policy in accordance with the requirements of the securities laws, including the disclosure required by the applicable Commission filings. 6. No Indemnification. The Company shall not indemnify any current or former Executive Officer against the loss of Erroneously Awarded Compensation, and shall not pay, or reimburse any current or former Executive Officers for premiums for any insurance policy to fund such Executive Officer’s potential recovery obligations. 7. Effective Date. This Policy shall be effective as of the Effective Date. 8. Amendment and Interpretation. The Compensation Committee may amend this Policy from time to time in its discretion and shall amend this Policy as it deems necessary or advisable to reflect the regulations adopted by the Commission and to comply with any rules or standards adopted by the NYSE. The Compensation Committee may at any time in its sole discretion, supplement, amend or terminate any provision of this Policy in any respect as the Compensation Committee determines to be necessary or appropriate. The Compensation Committee shall interpret and construe this Policy and make all determinations necessary or advisable for the administration of this Policy. It is intended that this Policy be interpreted in a manner that is consistent with the requirements of Section 10D of the Exchange Act and Rule 10D-1 thereunder and Section 303A.14 of the NYSE Listed Company Manual and any other applicable rules adopted by the Commission. 9. Other Recoupment Rights. The Compensation Committee intends that this Policy will be applied to the fullest extent of the law. The Compensation Committee may require that any employment agreement, equity award agreement or similar agreement entered into on or after the Effective Date shall, as a condition to the grant of any benefit thereunder, require the party thereto to agree to abide by the terms of this Policy or implement arrangements designed to facilitate the administration hereof. Although not a prerequisite to enforcement of this Policy, each Executive Officer shall be required to sign and return to the Company the Acknowledgment Form attached hereto as Exhibit A pursuant to which 5
Page 109
such Executive Officer will agree to be bound by the terms and comply with this Policy. Any right of recovery under this Policy is in addition to, and not in lieu of, any other remedies or rights of recovery that may be available to the Company pursuant to the terms of any employment agreement, equity award agreement, or similar agreement and any other legal remedies available to the Company. 10.Successors. This Policy shall be binding and enforceable against all current and former Executive Officers and their beneficiaries, heirs, executors, administrators or other legal representatives. 6
