Prospectus

shares

HMH Holding Inc.

Class A common stock

This is our initial public offering. We are offering shares of our Class A common stock.

Prior to this offering, there has been no public market for our Class A common stock. It is currently estimated that the initial public offering price will be between $ and $ per share of Class A common stock. We have applied to list our Class A common stock on The Nasdaq Global Select Market (“Nasdaq”) under the symbol “HMH.”

We are an “emerging growth company” as that term is used in the Jumpstart Our Business Startups Act of 2012, and as such, we have elected to take advantage of certain reduced public company reporting requirements for this prospectus and future filings. See “Risk factors” and “Summary—Emerging growth company status.”

We have two classes of common stock: Class A common stock and Class B common stock. Upon completion of this offering and the reorganization transactions described herein, holders of shares of our Class A common stock will be entitled to one vote for each share of Class A common stock, and holders of shares of our Class B common stock will be entitled to one vote for each share of Class B common stock, held of record on all matters on which stockholders are entitled to vote generally. See “Description of capital stock.” Upon consummation of this offering, the Principal Stockholders (as defined herein) will hold 100% of the shares of Class B common stock that will entitle them to % of the combined voting power of our common stock (or % if the underwriters exercise in full their option to purchase additional shares of Class A common stock). This offering is being conducted through what is commonly referred to as an umbrella partnership-C corporation, or “Up-C,” structure. The Up-C structure provides each Principal Stockholder with the tax advantage of continuing to own interests in a pass-through structure and provides potential future tax benefits for us and such Principal Stockholder when and if such Principal Stockholder ultimately exchanges its B.V. Non-Voting Shares (as defined herein) (or, in the case of Akastor (as defined herein), its B.V. Non-Voting Class B Shares (as defined herein) and Mercury HoldCo Inc. shares) and its shares of our Class B common stock for shares of Class A common stock. See “Corporate reorganization.” We intend to, among other things, use $ million of the net proceeds from this offering to pay the cash consideration portion of the purchase price to purchase an aggregate B.V. Voting Class A Shares and B.V. Voting Class B Shares (each as defined herein) from Baker Hughes (as defined herein) and/or Akastor pursuant to the corporate reorganization. See “Use of proceeds.”

Investing in our Class A common stock involves risks. See “Risk factors” beginning on page 38 to read about factors you should consider before buying shares of our Class A common stock.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

NCS = Norwegian Continental Shelf

Approximately 75% of our installed base of equipment serves the offshore drilling market, which is more highly regulated, more demanding and more technologically sophisticated than is typically encountered in the onshore market. As a result, offshore operators require highly engineered equipment and technical support services to keep their operations running safely, efficiently and productively. We believe that we are well-positioned to continue supporting and building our presence in the offshore drilling market as a result of our full, integrated suite of mission-critical drilling solutions, highly technical expertise, aftermarket services offerings and long experience providing and maintaining equipment in this industry.

We are a global company, with locations in 16 countries and sales in over 90 countries in 2024. We are headquartered in Houston, Texas, USA, with two major operational centers located close to key offshore areas in Houston, Texas, USA, and Kristiansand, Norway. In addition to our sales offices and direct sales efforts, we incorporate distributors and manufacturing sales representatives into our sales and marketing channels in certain limited locations to market our various offerings.

LOGO

We sell equipment and services to three core customer categories across the markets that we serve: (i) drilling contractors; (ii) operators, including both oil and gas exploration and production (“E&P”) companies and mining companies onshore and offshore; and (iii) manufacturers, consisting of shipyards and manufacturers of capital equipment. In addition to providing a range of equipment, spare parts, recurring aftermarket services and digital solutions to the onshore and offshore oil and gas drilling industry, we provide equipment and services to the onshore and subsea mining industry. Over our 125-year history, we believe we have developed trusted relationships with our customers and a strong reputation across industries with recognizable brand names, such as Hydril Pressure Control (“Hydril”), VetcoGray, Wirth and Maritime Hydraulics.

Health, Safety, Security and Environment (“HSSE”) is a key component of our organizational culture, and we strive to cultivate an HSSE-focused mindset among our employees and in connection with our activities. Our employees are expected to advance our corporate HSSE values and principles, including caring for the environment and prioritizing the safety and well-being of our employees and other stakeholders.

We have an asset-light business model through the leveraging of our existing operating footprint and original equipment manufacturer (“OEM”) business model and are well positioned to grow and scale our business with low incremental investment and capital expenditures. During the three months ended March 31, 2025, our net income was $5.9 million (or 3.0% of revenue) (as compared to net income of $8.5 million during the three months ended March 31, 2024) and our Adjusted EBITDA (as defined herein) was $29.9 million (or 15.1% of revenue), while capital expenditures, including development costs, represented only 1.2% of revenue. During the year ended December 31, 2024, our net income was $52.0 million (or 6.2% of revenue) (as compared to net income of $17.4 million during the year ended December 31, 2023) and our Adjusted EBITDA was $158.4 million (or 18.8% of revenue), while capital expenditures, including development costs, represented only 2.2% of revenue. Having an asset-light business allows us to generate a strong adjusted return on capital employed (“Adjusted ROCE”), a metric that we use to evaluate the profitability of our capital employed in our business operations. During the three months ended March 31, 2025 and the year ended December 31, 2024, our Adjusted ROCE was 3.5% and 19.7%, respectively. Adjusted EBITDA and Adjusted ROCE are non-GAAP financial measures. Please see “—Summary historical and pro forma financial data—Non-GAAP financial measures” for the definitions of Adjusted EBITDA and Adjusted ROCE and a reconciliation of Adjusted EBITDA and Adjusted

ROCE to our most directly comparable financial measures calculated and presented in accordance with generally accepted accounting principles in the United States of America (“GAAP”).

HMH B.V. was formed on October 1, 2021, through the combination of Baker Hughes’s Subsea Drilling Systems pressure control business and Akastor’s MHWirth drilling equipment business. As of May 20, 2025, 50% of HMH B.V.’s ordinary shares were held by Baker Hughes, and 50% of HMH B.V.’s ordinary shares were held by Akastor. Baker Hughes is an energy technology company with a diversified portfolio of technologies and services that span the energy and industrial value chain. Akastor is a Norway-based oil services investment company with a portfolio of industrial and financial holdings.

Together with our traditional business lines, we are embracing new opportunities in adjacent industries, including subsea mining. We approach all industries with a commitment to quality, safety and value. In even the most demanding environments, we strive to deliver value-adding products and services.

Our history and brands

Although the HMH trade name was created in connection with the formation of HMH B.V. in 2021, many of our product lines have been associated with the manufacture of highly engineered, mission-critical equipment for the oil and gas drilling industry for decades, and in the case of Wirth, for more than 125 years. Building on our legacy of historical brands, and with an eye towards innovation, we have created a comprehensive portfolio of products, systems and services for offshore and onshore drilling, subsea and onshore mining and certain large and complex construction applications. We continue to build on our legacy of historical brands such as Maritime Hydraulics, Wirth and Hydril, among others, giving us a unique opportunity to innovate in different segments and expand on our existing portfolio.

Many of our product lines have been in existence for decades, providing us opportunities to pursue improvements and innovations as our customers grow and undertake new challenges. Wirth developed its first mud pump in 1905, and since then has continuously worked to improve the portfolio of mud pump designs. Wirth was also one of the pioneers of pile top drill rigs and reverse circulation drilling. Hydril Company, a name derived from the term “Hydraulic Drilling Equipment,” was formed in 1933. During that decade, it produced the first hydraulically operated blowout preventer (“BOP”). We reached another milestone when we began delivering drawworks and pyramid masts and substructures for onshore rigs in 1950.

Maritime Hydraulics, which was established in 1968, launched the drilling industry in Kristiansand, Norway in support of Norway’s development of offshore oil production in the early 1970s. In the 1980s, Maritime Hydraulics built its first top drives, of which we have delivered nearly 400 units. In addition to our drawworks portfolio, we launched the award-winning RamRig^™ in 1996, a highly efficient compensating system for semisubmersible and drillship operations.

The long history of our brands and high customer recognition enables us to pursue research and development (“R&D”) efforts to innovate existing product and service offerings for our customers, such as the fully electric BOP in development that we believe is the first of its kind and will pave the way for safer, more efficient and environmentally sustainable drilling operations. As compared to traditional hydraulic systems, a fully electric BOP minimizes downtime and reduces maintenance costs by providing active monitoring, real-time data and remote-control capabilities. We are also developing several other cutting-edge technologies and solutions, such as a newly designed rotating control device for managed pressure drilling and enhanced pressure assisted shearing for BOPs.

Our global footprint and large installed base

We have a large, scalable and geographically diverse footprint with crucial customer proximity. Across our presence in 16 countries, we operate 34 physical locations and delivered sales in over 90 countries in 2024. There are over 1,100 installations with our equipment globally. Our equipment offerings can be utilized in both offshore and onshore drilling markets, and we maintain locations near strategically important offshore drilling regions, including the Gulf of Mexico, the North Sea, South America, West Africa and the Middle East.

Approximately 75% of our installed base serves the offshore market. We have delivered mission-critical rig equipment packages (defined as two or more integrated systems), either pressure control systems, topside equipment or a full suite of products, to 124 offshore drilling rigs and platforms. Offshore rigs with our equipment packages operate primarily in international markets, including 22 floaters in the North Sea and Europe, 17 in Asia, 16 in Central and South America, 15 in North America and nine in Africa and the Middle East. Jack-ups and platform rigs with our installed base also operate primarily in international markets, including 22 in the North Sea and Europe, nine in Africa and the Middle East, seven in North America and seven in Asia.

Our operations are heavily focused on aftermarket services and sales of spare parts, which accounted for 42.1% and 30.3%, respectively, of our revenue during the three months ended March 31, 2025 and 43.4% and 29.4%, respectively, of our revenue during the year ended December 31, 2024. A substantial majority of our revenues from aftermarket services and sales of spare parts are derived from the offshore oil and gas industry. Our ability to generate resilient and recurring revenues from aftermarket services and sales of spare parts is a direct result of our current and growing base of equipment installations globally. Increased drilling activity and wear-and-tear across our large installed base will continue to drive increased revenue from aftermarket services and sales of spare parts.

Our global supply chain initiates and drives innovation and cost reductions by establishing long-term partnerships with qualified suppliers and optimizing inventory.

Our products

We provide a broad suite of mission-critical, highly engineered equipment to the global oil and gas drilling and mining industries. Our equipment generally falls under two broad categories: (i) pressure control systems, including BOPs, and (ii) topside equipment, which is comprised of hoisting and rotating systems and drilling (mud) circulating systems. We have also developed a comprehensive suite of digital solutions that are integrated with, and augment the functionality of, many of the products we provide, as described under “—Digital innovation.”

LOGO

Pressure control systems

Our pressure control systems are critical pieces of safety equipment that are integral for the safe operation of oil and drilling rigs. We provide the following primary pieces of equipment under our pressure control systems:

•

Blowout Preventers (BOPs): The BOP is a series of valves designed to either shear the drillstring or close around the drillstring (via pipe rams in a ram BOP or by an annular BOP) to stop the uncontrolled flow of hydrocarbons from the wellbore. BOPs can either be placed on the seabed (a subsea BOP) or at surface as is commonly done in offshore jack-ups and onshore rigs.

•

BOP Control Systems: Given the criticality of the BOP, the control systems monitor, activate and test the BOPs. In the event of an issue, the control system will activate the BOP by either: (i) a signal sent by an operator, (ii) a loss of signal from surface or (iii) manual activation by a remotely operated vehicle.

•

Drilling Risers: The subsea riser is a buoyant pipe that the drillstring runs through and provides a conduit between the rig and the BOP or wellhead to transport drilling mud, as well as providing additional pipes that function as hydraulic fluid supply and choke and kill fluid lines.

•

Wellhead Connectors: Our H-4 type wellhead connectors are the industry leader in performance ratings and installed base. These devices connect a subsea BOP stack to the wellhead and are used on other OEMs’ BOP stacks.

Topside equipment

Our highly engineered topside equipment, which consists of hoisting and rotating systems and drilling (mud) circulating systems, is critical to a rig’s ability to lift, manage and rotate the drillstring and circulate drilling fluids through the wellbore.

Hoisting and rotating systems

We provide the following primary pieces of equipment under our hoisting and rotating systems:

•

Top Drive: The top drive sits within the upper portion of the derrick and applies rotation / torque to the drillstring during drilling operations. We have a long-standing history of providing high-spec, highly reliable top drives that are used by many of the largest global drilling contractors.

•

Iron Roughneck and Pipe Handling: The iron roughneck is used to make and later break connections in the drillstring, removing personnel from a very dangerous step in the process. The increased drilling cadence in both onshore and offshore makes the iron roughneck a key service item.

•

Derrick and Drawworks: The derrick and drawworks are the weight bearing components of the rig that provide the lifting capacity to the rig.

Drilling (mud) circulating systems

We provide the following primary pieces of equipment under our drilling (mud) circulating systems:

•

Mud Pumps: The mud pump is utilized to circulate drilling fluid (mud), which is critical as the fluid provides the primary pressure control, hole cleaning and friction reduction during drilling. As wellbores are increasingly complex and longer, operators require higher horsepower mud pumps to circulate fluid.

•

Slurry Pumps: Slurry pumps are our mud pumps that have been redesigned to be utilized in the transport of slurry in mining applications.

•

Mud Mixing and Control Systems: The drilling fluid needs to be carefully mixed and monitored to achieve required properties for the specific operation, such as weighting to avoid either the loss of well control (underweight) or loss of fluid (overweight).

Our services

Our aftermarket services generally fall under two broad categories:

•

Transactional Services: Transactional services are services on installed equipment, such as the overhaul and repair of installed equipment, recertifications and field labor.

•

Integrated Solutions: We combine various tools, software and services to provide comprehensive digital solutions designed to drive productivity, safety and efficiency in our customers’ operations.

As depicted in the graphic below, our growing portfolio of integrated solutions is designed to deliver clear value to our customers by increasing operational efficiency and reducing costs.

LOGO

Digital innovation

We have invested in developing digital solutions to support the safe and efficient operations of our equipment and are a leading provider of next-generation monitoring and control systems driving the future of drilling. Our digital solutions include products and services that enable operational optimization such as remote drilling automation and condition-based monitoring. Our real-time monitoring and analytics capabilities provide operational and service insights that can save our customers time and money. These offerings are an important part of our business as they provide recurring and stable revenue and upgrade opportunities to older equipment as our customers continue to invest in their own digitalization initiatives. In addition, the horizontal nature of this technology provides us with the opportunity to establish a presence in new adjacent end markets.

In alignment with our customers, we have taken the approach of building our digital solutions in a cloud-first, modern and open architecture. This provides our customers the ability to integrate our digital solutions into their existing workflow and monitoring systems and allows for the optimization of the entire well life cycle at lower costs. The differentiated nature of our digital solutions and value proposition for our customers provides a strong recurring base of revenue to our core business.

For example, we provided a next-generation rig equipment package to a customer as depicted below, which we believe has the potential to significantly reduce the number of personnel required to operate the rig relative to existing equipment.

LOGO

Spare parts

We provide a broad range of replacement and spare parts for installed equipment used in both onshore and offshore oil and gas drilling operations. Our spare parts replace existing installed components on rigs that have weathered the wear-and-tear involved with repetitive use throughout the lifecycle of a rig, especially in harsh offshore environments, and keep rigs functioning safely and efficiently. Additionally, our spare parts sales help customers bring back into service rigs that have been warm stacked or cold stacked. Our spare parts are compatible with our current and growing base of equipment installations globally, and such spare parts are also compatible with, and can serve as replacements for, equipment from most other major OEMs.

Our business model

We offer drilling solutions through sales of projects and products, aftermarket services on our installed base of equipment and sales of spare parts. During the three months ended March 31, 2025, we derived $54.7 million in revenue, or 27.6% of our revenue, from sales of projects and products, $83.5 million in revenue, or 42.1% of our revenue, from aftermarket services and $60.2 million in revenue, or 30.3% of our revenue, from sales of spare parts. During the year ended December 31, 2024, we derived $229.1 million in revenue, or 27.2% of our revenue, from sales of projects and products, $366.2 million in revenue, or 43.4% of our revenue, from aftermarket services and $248.0 million in revenue, or 29.4% of our revenue, from sales of spare parts.

Sales of projects and products

We define a project as the sale of two or more integrated systems that are designed to work together on a single drilling rig. Project sale revenue is derived primarily from new construction, reactivation or, less commonly, a significant capital upgrade to an existing drilling rig. Project sales are largely tied to the offshore rig newbuild cycle, particularly to the construction of floaters and jack-ups. Such projects entail substantial commissioning, manufacturing and installation, and thus shipyards or other customers seeking to outfit a newbuild or significantly upgrade an existing drilling rig prefer OEMs with differentiating expertise and reliability such as us. Production, delivery and installation on a project can span from 1.5 to 3.5 years. For a newbuild rig, we can provide an entire package of drilling equipment, which, based on the previous build cycle that ended in 2015, represents a revenue opportunity of approximately $45 million in sales for a jack-up rig, approximately $200 million to $300 million in sales for a floater and approximately $15 million to $25 million in sales for a land rig.

In addition to project sales, we sell new pieces of equipment and components to our offshore customers. As the offshore drilling market has largely avoided ordering newbuild rigs over the past seven to ten years, demand for our products has stemmed largely from wear-and-tear on the installed base as components age and operating requirements increase. Product sale revenue is derived from customers seeking to upgrade the capabilities of existing drilling rigs or replace existing equipment that is in need of major refurbishment or no longer operational, including equipment and components needed in connection with bringing warm stacked or cold stacked rigs back into service. Our project and product dynamics are similar across the onshore drilling market; however, in the current environment, onshore customers are more likely to embark on newbuild rig programs than in the offshore drilling market, especially in the Middle East.

We are one of the few global OEMs capable of delivering a comprehensive drilling equipment package that meets the stringent requirements demanded by major international oil and gas E&P companies and national oil companies to operate in harsh, offshore environments and environmentally sensitive areas. As of May 20, 2025, we and our predecessor companies have delivered integrated systems to over 140 offshore rigs (including 124 marketed rigs) since 1983, have supplied components to over 800 offshore installations since 1975 and have supplied components to over 300 onshore rigs since 2012.

Our comprehensive product offerings, manufacturing expertise and leading-edge technology allow us to provide all the critical components needed for a modern drilling rig capable of operating in challenging conditions and environmentally sensitive areas for customers who are acutely focused on safe and responsible drilling operations. These include integrated topside drilling packages for jack-ups, floaters and platforms; integrated pressure control systems deployed onshore and offshore, both at surface and subsea; and equipment certified for operation on the Norwegian Continental Shelf.

Aftermarket services

We have over 1,100 equipment installations globally. Demand for aftermarket services on existing rigs is largely driven by the installed base of our equipment already in operation, the intensity at which that equipment is being run and the age of the equipment. In the case of subsea BOPs and drilling risers, regulators in the United States and Europe mandate regular inspections and certification of the equipment, which are performed by the OEM.

In the offshore market, we are the provider of choice to inspect, maintain, recertify and repair, either by mandate or industry best practices, the equipment that we have delivered. Given the complexities of offshore equipment, even in situations where the OEM is not mandated to perform the service, it is uncommon for a customer to engage a third party to perform the work. We leverage our global operating footprint and supply chain to deliver this service to our customers in a timely and cost-effective manner. For example, on average, we provide recurring aftermarket services on our installed BOPs for over 25 years, which includes recertification every five years, regular monitoring and maintenance on an as-needed basis.

The equipment with the highest aftermarket service revenue potential is the BOP, followed by mud pumps, iron roughnecks and associated pipe handling equipment, subsea risers and top drives. As is typical in the industry, once we install equipment we tend to generate nearly all of the service revenue associated with the equipment. Following an initial construction phase, a typical rig, depending on type, will operate for around 20 to 30 years and will be subject to routine regulatory inspections and maintenance, periodic recertifications of pressure control equipment and potentially overhaul.

Sales of spare parts

LOGO

Source: Company management

We are able to partner with customers to deliver equipment sales, spare parts sales and aftermarket services through the entire operating life of a rig to provide the performance, efficiency and safety they have come to expect. Such partnership is exemplified by our contractual service agreements (“CSAs”) with customers, which are long-term agreements under which we provide a tailored, unique solution to our customers’ aftermarket service needs for between five and ten years after initial installation. We provide our customers with transparent pricing and payment structures that are predictable. We leverage our experience and expertise to take advantage of predictive analytics and continuous certification to improve equipment availability and reduce operational costs for our customers while also limiting the impact of any potential supply chain slowdowns on our customers’ equipment. With our CSA offerings, for example, we have partnered with our customers to enhance BOP system availability by transferring the responsibility for BOP performance, including the management and servicing of equipment, to us. In addition to mitigating risks associated with downtime and repair costs, our customizable structures can be fine-tuned to address long-term ownership costs.

We expect to see the cadence of aftermarket and spare parts demand from onshore rigs continue to increase in the near to medium term due to the increased pace of drilling in both the conventional and unconventional onshore markets, coupled with the drilling of more complex wells and longer laterals in challenging subsurface environments, thus increasing the wear-and-tear on equipment.

Customers and end markets

We serve customers in multiple industries and strive to provide reliable and safe solutions that satisfy our customers’ needs. Our primary end market is the upstream oil and gas industry, both offshore and onshore. A growing share of our revenue base is attributable to our businesses that support industries sitting outside, or adjacent to, the oil and gas sector, and we see further opportunity to continue to expand our footprint in these adjacent end markets.

We sell equipment and services to three core customer categories across the markets that we serve: (i) drilling contractors; (ii) operators, including both oil and gas E&P companies and mining companies onshore and offshore; and (iii) manufacturers, consisting of shipyards and manufacturers of capital equipment. Our largest customer segment is drilling contractors, both offshore and onshore. We provide projects, products and services for drilling contractors in order to support essential drilling operations for E&P customers internationally. Our primary exposure to E&P operators is derived through the equipment supplied to platform rigs and, to a lesser degree, land-based equipment in international markets. In both cases, the rigs themselves are typically owned by the E&P operator, who may operate the rig themselves or contract out drilling operations to a drilling contractor. For mining operators, we sell products and services directly to mining companies, and we typically sell equipment directly to those engaged in hard rock mining operations, in particular. Finally, for newbuilds, we provide complete projects directly to a shipyard, but with the influence of the drilling contractor or E&P operator who is driving the order.

Our industry is focused on operating in a safe, minimally impactful and efficient manner. Accordingly, our products are critical components and of strategic importance to our customers, and we are in constant and active dialogue with our customers to develop new solutions, identify improvements and optimize performance of existing equipment. These partnerships reinforce our credibility, lending assurance to reliability and performance within the industry, which in turn attracts new customers. Furthermore, our broad geographic exposure reflects that of our customers’ global presence, providing timely service across their global operations when necessary.

While we serve a variety of end markets, the majority of our equipment and services are deployed in oil and gas drilling operations, particularly offshore and international drilling operations. Beyond the core oil and gas end markets, we supply a large and growing installed base of mining customers, primarily serving hard rock mining globally. Our product offerings, such as our slurry pumps, may be retrofitted and designed to service the needs of the both the conventional mining industry and also the subsea mining and research industries. We have seen increasing demand for our equipment from mining customers. Renewable energy technologies rely heavily on the expanded production of certain minerals, including lithium, cobalt and rare earth metals.

Our competitive strengths

We have a number of strengths that we believe will help us successfully execute our business strategies, including:

Global provider of innovative drilling equipment, digital solutions and services

continuously improve existing product and service offerings for our customers while also developing innovative new technologies, such as our commercial 20,000 psi BOP capability and a fully electric BOP. With development, manufacturing and service locations distributed throughout 16 countries, our global integrated operations facilitate the efficient delivery of our products to the operating sites of our customers and servicing of our installed base of equipment.

Large global installed base and integrated operations provide recurring and resilient aftermarket service and spare parts revenues

We have over 1,100 equipment installations globally, approximately 75% of which serves offshore oil and gas drilling operations. As an OEM of premier equipment and with our large and growing installed base of equipment, we are well positioned to capture recurring revenues arising from aftermarket services for such equipment. During 2023, 2024 and the three months ended March 31, 2025, aftermarket services comprised 41.8%, 43.4% and 42.1%, respectively, of total revenues and sales of spare parts comprised 34.2%, 29.4% and 30.3%, respectively, of total revenues. We anticipate aftermarket services and spare parts sales will continue to represent a substantial portion of our revenue as increased drilling activity is expected to result in our customers requiring additional aftermarket services and spare parts to sustain an increased cadence of activity globally. Following an initial construction phase, a typical rig, depending on type, will operate for around 20 to 30 years and will be subject to routine regulatory inspections and maintenance, periodic recertifications of pressure control equipment and potentially overhaul. We are able to partner with customers to deliver equipment sales, spare parts sales and aftermarket services through the entire operating life of a rig, including the overhaul and repair of installed equipment, recertifications and field labor. Further, we collaborate with our customers to implement our proprietary integrated digital solutions, including DrillPerform, RiCon, DrillCERT, SeaLytics and DEAL, which support safe and efficient operations through remote monitoring of machine health, predictive analytics and operational optimization features such as drilling automation. The integration of our digital solutions with our equipment provides further opportunities for recurring revenues from customers.

Trusted partner for mission-critical services and products such as BOPs and BOP control systems

We believe our equipment offerings are essential, mission-critical components of a drilling rig and help promote safe and effective well construction and drilling operations. For example, our pressure control systems, including our subsea BOPs, 20,000 psi BOPs and BOP control systems, assist our customers with maintaining safe drilling operations, especially in deepwater offshore, environmentally sensitive or high-pressure applications. Due to the highly regulated, technologically demanding and sophisticated nature of the offshore drilling market, we believe we are one of only a few providers of subsea BOPs accepted by the major drilling contractors and operators for use in key offshore geographies, such as the Gulf of Mexico and the Norwegian sector of the North Sea. We believe customers prefer suppliers of BOPs and similar critical equipment and services with a demonstrated record of performance and safety, such as HMH. Through multi-year CSAs, we leverage our expertise and predictive analytics to design a unique blend of products and services for our customers aimed to increase equipment reliability, decrease downtime, reduce operational costs and ultimately lead to increased productivity and revenues for our customers. As a result of our extensive experience, track record of safety and reliability, comprehensive suite of offerings and global service network, we are a partner of choice for many of the largest independent E&P companies, national oil companies, drilling contractors, service providers and shipyards.

Exposure to strong expected growth in offshore and international onshore oil and gas drilling markets

and brownfield oil and gas capital expenditures are projected to be over $700 billion in each of 2025, 2026 and 2027, an increase of almost 60% as compared to 2020. As global capital expenditures for the oil and gas industry increase, the offshore rig market is also approaching activity levels not seen in nearly a decade. Rystad Energy forecasts a compounded annual growth rate of over 6% for floater rigs between 2024 and 2027. Such increase in oil and gas exploration and drilling activity is expected to result in increased demand for our equipment, aftermarket services and spare parts. Further, due to the longer cycle times associated with offshore oil and gas projects as compared to onshore activity, we are well poised to benefit from the duration and stability of offshore activity. We believe our recurring revenues from aftermarket services and spare parts will benefit from the expected increase in offshore activity.

Asset-light business model and scalable footprint provide earnings resilience

As a supplier of equipment, aftermarket services and spare parts with increased flowthrough of product manufacturing at our current facilities, we have an asset-light business model that is well positioned to capture incremental operating margin expansion as revenues continue to grow. With our manufacturing and supply chain facilities strategically located near key offshore and onshore markets, we are well positioned to grow our business and capitalize on increased drilling activity with limited incremental investment in expanding operations and capital expenditures. During the three months ended March 31, 2024 and 2025, our capital expenditures, including development costs, represented only 2.4% and 1.2%, respectively, of revenue, while revenue increased by 2.4%, net income decreased by 30.5% and Adjusted EBITDA decreased by 4.6% from the three months ended March 31, 2024 to the three months ended March 31, 2025. During the years ended December 31, 2023 and 2024, our capital expenditures, including development costs, represented only 3.1% and 2.2%, respectively, of revenue, while revenue increased by 7.4%, net income increased by 198.6% and Adjusted EBITDA increased by 29.3% from the year ended December 31, 2023 to the year ended December 31, 2024.

Experienced management team that is well-positioned to grow the business through new product development, organic growth and acquisitions

Most members of our executive team have been active in the drilling segment for over 20 years and are well suited to identify trends and opportunities in the drilling industry. Our management team has a proven track record of profitably scaling revenue across a global portfolio through the cultivation of long-standing customer relationships, development and successful commercialization of new technologies and optimization of international manufacturing capabilities, supply chain networks and corporate processes, including the negotiation and execution of large contracts with shipyards and drilling contractors. In addition to organic growth, our management team has an extensive track record of identifying acquisition targets and executing transactions, having executed over 100 transactions throughout their combined careers. Many of these transactions involved complex structures including joint ventures, new efforts in foreign markets and corporate carve-outs. They also have a track record of successfully integrating acquired businesses, as demonstrated by the merger of Akastor’s MHWirth drilling equipment business and Baker Hughes’s Subsea Drilling Systems pressure control business that formed HMH.

Our strategy

We intend to achieve our primary business objectives by successfully executing on the following strategies through a combination of organic and inorganic growth investments:

Leverage global footprint and large installed base to capture growth in offshore drilling capital expenditures

increase in capital expenditures and drilling activity in the offshore oil and gas market through our global footprint of manufacturing and supply chain facilities near key markets and our large installed base.

As drilling rigs work and age, and as increasingly complex wells generate more wear-and-tear, we benefit from the resulting additional demand for our products, aftermarket services and spare parts. Historically, we have seen aftermarket-driven demand growth as offshore drilling activity increases, and we expect that pattern to continue. Additionally, as our customers bring offshore rigs that are warm stacked or cold stacked back into service, the revenue base for our aftermarket services and spare parts increases. This is in addition to our benefitting from the revenue opportunities from equipment upgrades associated with such reactivations.

Furthermore, opportunities for newbuild offshore rigs may arise as rig demand increases and the market tightens further. For a newbuild rig, we can provide an entire package of drilling equipment, which, based on the previous build cycle that ended in 2015, represents a revenue opportunity of approximately $45 million in sales for a jack-up rig, approximately $200 million to $300 million in sales for a floater and approximately $15 million to $25 million in sales for a land rig. Additionally, we expect such opportunities for newbuilds to increase our ongoing service revenue stream as new rigs are generally put directly into active service.

Continue to enhance customer offerings through both improvement of existing technologies, increased digitalization and expansion into additional offshore services

We believe that we have been, and will continue to be, at the forefront of technological and digital innovation in the drilling industry. We actively invest in R&D efforts and are developing several cutting-edge technologies and solutions, such as hybrid energy solution rigs, riserless drilling, a newly designed rotating control device for managed pressure drilling, enhanced pressure assisted shearing for BOPs and an electric BOP.

We also invest in developing digital solutions, such as DrillPerform, RiCon, DrillCERT, SeaLytics and DEAL, which use real-time data and analytics that allow us to better understand our customers’ needs. Our innovative equipment offerings and integrated digital solutions create value for our customers by increasing efficiency, decreasing downtime, reducing cost and enhancing safety. In recent years, we have developed integrated digital control solutions that enable remote drilling operations and increase automation in the drilling process. We will continue pursuing technological and digital advancements that we believe will lead to additional avenues for growth and enhance our position as the partner of choice for our customers.

We continue to explore opportunities to provide other services to our existing offshore drilling contractor customer base. For example, we provide inspection services on risers that were not originally provided or installed by us.

Leverage historical capability to capture growth and market share in onshore drilling capital expenditures

Our current suite of drilling products is well-suited for large, high-torque and high-horsepower onshore rigs. While our installed base of equipment on onshore rigs is relatively small compared to offshore rigs, we have extensive capabilities in this area and will focus on both organic and inorganic investments to increase our penetration of new equipment sales for land drilling. The onshore drilling market is relatively more fragmented with a more diverse customer base than the offshore drilling market and represents a largely untapped aftermarket opportunity for us. We have the ability to provide a broad suite of products (over 110,000 drawings of parts are available), spare parts and repair services that are compatible with equipment provided by most major manufacturers. Recent expansion in the Middle East further enhances this capability, and we are pursuing multiple additional marketing channels to increase this activity on a global basis.

Utilize industry expertise and manufacturing capabilities to continue growth in current onshore and subsea mining businesses

We will continue to utilize our engineering and manufacturing expertise for the application of our products and services for use in, and the development of solutions for, adjacent and complementary markets such as onshore and subsea mining. For example, we have modified and deployed our drilling mud pumps to serve in the onshore mining sector as heavy-duty slurry pumps, which are used to transport and process mining material through high-pressure slurry lines. We are also pursuing similar opportunities in subsea mining, where our mud pump systems meet the pressure and temperature requirements for deep sea mining operations. Our technologies and products have a wide range of applications across industries, and we will actively embrace such opportunities for growth where the economics and industry outlook are favorable.

Expand into adjacent markets that are consistent with our core competencies

We are exploring adjacent segments that draw on similar skill sets as our core businesses. These include moving beyond the drilling rig for oil and gas customers and making completion, intervention and production equipment and services. We have a long-standing track record of developing, designing, manufacturing and delivering highly engineered equipment that is relied upon by customers operating in regions and environments with significant complexity, regulatory scrutiny and financial risk involved. We believe that this experience, technical know-how and reputation are a key differentiator for our organization, which positions us well to be able to expand our portfolio of oil and gas related products.

We believe it is important to focus on our core competencies around manufacturing highly engineered products, expanding market access to products globally, commercializing new technology and driving cost and operational efficiency. Other adjacent industries could include renewables, marine products and services and industrial business with equipment similar to our drilling equipment. Our global footprint, manufacturing capacity, operational capability and experience growing businesses globally allow us to assess and execute on this strategy.

Capitalize on management experience to grow business through acquisitions and integration

HMH B.V. was formed through the combination of Baker Hughes’s Subsea Drilling Systems pressure control business and Akastor’s MHWirth drilling equipment business. Our management team successfully combined these businesses and quickly established our corporate infrastructure to support the new company. Our management team has extensive mergers and acquisitions (“M&A”) and integration experience in prior roles at other companies. Given management’s experience and prior track record, we are well positioned to recognize and capitalize on trends in the industry.

Our global reach and footprint position us well to identify, source, acquire and integrate businesses that can help us continue to grow in core and adjacent markets, as exemplified by our acquisition (the “Drillform Acquisition”) of Drillform Technical Services Ltd. (“Drillform”) in 2024. We believe there is a substantial opportunity set of potential acquisition candidates that will be available over the next several years.

We intend to invest in businesses that generally have similar characteristics to our own, such as an ongoing aftermarket component, proprietary technology and a capital-light business model. We will also focus on opportunities that can be scaled across our global platform and leverage our management team’s experience in driving growth. We have a strategic and financial approach to evaluating potential acquisitions to confirm that they meet certain criteria, with a preference for potential acquisition targets that would add new products or technologies, are complementary to our core product offerings and end markets, have a strong history of generating high returns and have an asset-light business model.

Continue to use conservative balance sheet approach and target businesses with light capital needs

Our management team has established conservative financial principles to guide us through decision-making in any potential commodity cycle. Our asset-light business model, the recurring revenues associated with our aftermarket services and our Free Cash Flow generation mitigate our exposure to the impacts of commodity downturns and provide us with the flexibility to pursue growth opportunities. Even so, we remain focused on maintaining a conservative leverage profile and maintaining an asset-light business model.

The Tax Receivable Agreement will generally provide for the payment by us to the Principal Stockholders of 85% of the net cash savings, if any, in U.S. federal, state, local and foreign income tax and franchise tax that we actually realize (or are deemed to realize in certain circumstances) in periods after this offering as a result of, as applicable to each Principal Stockholder, (i) certain increases in tax basis that occur as a result of our acquisition (or deemed acquisition for U.S. federal income tax purposes) of all of such Principal Stockholder’s B.V. Voting Shares in connection with this offering or any portion of such Principal Stockholder’s B.V. Non-Voting Shares pursuant to the exercise of the Redemption Right or our Call Right, (ii) the utilization of certain net operating losses (“NOLs”) of Mercury HoldCo Inc. in the event that we acquire Mercury HoldCo Inc. shares pursuant to the exercise of the Hybrid Redemption Right and (iii) imputed interest deemed to be paid by us as a result of, and additional tax basis arising from, any payments we make under the Tax Receivable Agreement. Payments will generally be made under the Tax Receivable Agreement as we realize actual cash tax savings in periods after this offering from the tax benefits covered by the Tax Receivable Agreement. However, if we experience a change of control (as defined in the Tax Receivable Agreement) or the Tax Receivable Agreement terminates early (at our election or as a result of a material breach of our obligations thereunder), we could be required to make a substantial, immediate lump-sum payment in advance of any actual cash tax savings. Because we are a holding company with no independent

means of generating revenue, our ability to make payments under the Tax Receivable Agreement is dependent on the ability of HMH B.V. to make distributions to us in an amount sufficient to cover our obligations under the Tax Receivable Agreement.

HMH Inc. will retain the benefit of the remaining 15% of these cash savings. For additional information regarding the Tax Receivable Agreement, see “Risk factors—Risks related to this offering and ownership of our Class A common stock” and “Certain relationships and related party transactions—Tax Receivable Agreement.”

Principal executive offices and Internet address

Our principal executive offices are located at 3300 North Sam Houston Parkway East, Houston, Texas 77032, and our telephone number is (281) 449-2000. Following the closing of this offering, our website will be located

at www.hmhw.com. We expect to make our annual, quarterly and current reports, and amendments to those reports, and other information filed with or furnished to the Securities and Exchange Commission (“SEC”) available, free of charge, through our website, as soon as reasonably practicable after those reports and other information are electronically filed with or furnished to the SEC. Information on our website or any other website is not incorporated by reference into this prospectus and does not constitute a part of this prospectus.

Emerging growth company status

As a company with less than $1.235 billion in revenue during our last fiscal year, we qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As an emerging growth company, we may, for up to five years, take advantage of specified exemptions from reporting and other regulatory requirements that are otherwise applicable generally to public companies. These exemptions include:

•

in contrast to our reports under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), after we are public, the presentation in this prospectus includes only two years of audited financial statements and only two years of related Management’s Discussion and Analysis of Financial Condition and Results of Operations;

•

deferral of the auditor attestation requirement on the effectiveness of our system of internal control over financial reporting;

•

exemption from the adoption of new or revised financial accounting standards until they would apply to private companies;

•

exemption from compliance with any new requirements adopted by the Public Company Accounting Oversight Board requiring mandatory audit firm rotation or a supplement to the auditor’s report in which the auditor would be required to provide additional information about the audit and the financial statements of the issuer; and

•

reduced disclosure about executive compensation arrangements.

In addition, Section 107 of the JOBS Act also provides that an emerging growth company can use the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended (the “Securities Act”), for complying with new or revised accounting standards. This permits an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We are choosing to take advantage of this extended transition period and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for private companies.

We may take advantage of these provisions until we are no longer an emerging growth company, which will occur on the earliest of (i) the last day of the fiscal year following the fifth anniversary of this offering, (ii) the last day of the fiscal year in which we have equal to or more than $1.235 billion in annual revenue, (iii) the date on which we issue more than $1 billion of non-convertible debt over a three-year period or (iv) the date on which we are deemed to be a “large accelerated filer,” as defined in Rule 12b-2 promulgated under the Exchange Act.

We intend to (i) use $ million of the net proceeds from this offering to pay the cash consideration portion of the purchase price to purchase an aggregate B.V. Voting Class A Shares and B.V. Voting Class B Shares from Baker Hughes and/or Akastor pursuant to the corporate reorganization (see “Corporate reorganization”) and (ii) contribute all of the remaining net proceeds from this offering to HMH B.V. in exchange for a number of B.V. Voting Class A Shares and B.V. Voting Class B Shares such that the number of B.V. Voting Class A Shares and B.V. Voting Class B Shares, respectively, held by us (taking into account the B.V. Voting Class A Shares and B.V. Voting Class B Shares acquired by us from the Principal Stockholders pursuant to the corporate reorganization) equals the number of shares of Class A common stock sold by us in the offering. HMH B.V. intends to use $ million of the net proceeds received by it to repay all of the outstanding principal and accrued and unpaid interest under the Shareholder Loans (as defined herein) from Baker Hughes Holdings LLC and Akastor AS, which totaled $134.6 million as of March 31, 2025, and any remaining amounts for general corporate purposes, which may include funding for acquisitions, working capital requirements, capital expenditures and the repayment, refinancing, redemption or repurchase of indebtedness or other securities.

If the underwriters exercise in full their option to purchase additional shares of Class A common stock, we intend to contribute all of the additional net proceeds to HMH B.V. in exchange for an additional B.V. Voting Class A Shares and B.V. Voting Class B Shares. HMH B.V. intends to use such additional net proceeds for general corporate purposes, which may include funding for acquisitions, working capital requirements, capital expenditures and the repayment, refinancing, redemption or repurchase of indebtedness or other securities.

See “Use of proceeds.”

Dividend policy

Redemption rights of the Principal Stockholders

Under the Exchange Agreement, each Principal Stockholder party thereto will, subject to certain limitations, have the right, pursuant to the Redemption Right, to cause HMH B.V. to acquire or directly cancel all or a portion of its B.V. Non-Voting Shares, together with all or an equal portion of its shares of our Class B common stock, for (i) shares of our Class A common stock at a redemption ratio of one share of Class A common stock for each bundle of one B.V. Non-Voting Class A Share, one B.V. Non-Voting Class B Share and one share of our Class B common stock redeemed, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions, or, upon mutual agreement between such Principal Stockholder and us, (ii) an equivalent amount of cash, based on the trailing ten-day VWAP prior to the redemption date. Alternatively, upon the exercise of the Redemption Right, we (instead of HMH B.V.) will have the right, pursuant to the Call Right, to acquire each tendered bundle of one B.V. Non-Voting Class A Share, one B.V. Non-Voting Class B Share and one share of our Class B common stock directly from such Principal Stockholder for (a) one share of Class A common stock, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions, or, upon mutual agreement between such Principal Stockholder and us, (b) an equivalent amount of cash, based on the trailing ten-day VWAP prior to the redemption date. Under the Exchange Agreement, Akastor will, subject to certain limitations, also have the right, pursuant to the Hybrid Redemption Right (and in lieu of exercising the Redemption Right), to cause HMH Inc. to acquire all or a portion of its B.V. Non-Voting Class B Shares and all or a portion of its Mercury HoldCo Inc. shares, together with all or an equal portion of its shares of our Class B common stock, for (i) shares of our Class A common stock at an exchange ratio of one share of Class A common stock for each bundle of a specified number of Mercury HoldCo Inc. shares (representing indirectly an ownership interest in one B.V. Non-Voting Class A Share), one B.V. Non-Voting Class B Share and one share of our Class B common stock exchanged, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions and adjustments to account for any net assets held by Mercury HoldCo Inc. other than HMH B.V. Non-Voting Class A Shares, or, upon mutual agreement between Akastor and us, (ii) an equivalent amount of cash, based on the trailing ten-day VWAP prior to the exchange date. Our decision to mutually agree with a Principal Stockholder on whether to make a cash payment upon such Principal Stockholder’s election under the Redemption Right or the Hybrid Redemption Right will be made by our independent directors (within the meaning of the Nasdaq listing rules). Such independent directors will make such decision based on facts in existence at the time of the decision, which we expect would include the relative value of the Class A common stock (including trading prices for the Class A common stock at the time), the cash purchase price, the availability of other sources of liquidity (such as an issuance of preferred stock) to acquire or directly cancel the B.V. Non-Voting Shares (and, if applicable, the Mercury HoldCo Inc. shares) and alternative uses for such cash. The parties will agree to treat the exercise of the Redemption Right and the exercise of the Call Right, in each case to the extent permitted under applicable tax law, as purchases by

HMH Inc. of interests in HMH B.V. for U.S. federal income tax purposes that give rise to basis adjustments pursuant to Section 743(b) of the Code. In connection with any redemption of B.V. Non-Voting Shares and our Class B common stock pursuant to the Redemption Right, acquisition of B.V. Non-Voting Shares and our Class B common stock pursuant to our Call Right or acquisition of B.V. Non-Voting Class A Shares (indirectly through the acquisition of Mercury HoldCo Inc. shares), B.V. Non-Voting Class B Shares and our Class B common stock pursuant to the Hybrid Redemption Right, the corresponding number of shares of our Class B common stock will be cancelled. See “Certain relationships and related party transactions—Exchange Agreement.”

Tax Receivable Agreement

HMH Inc.’s acquisition (or deemed acquisition for U.S. federal income tax purposes) of the Principal Stockholders’ B.V. Voting Shares in connection with this offering or B.V. Non-Voting Shares (and, if applicable, Mercury HoldCo Inc. shares) pursuant to an exercise of the Redemption Right, the Call Right or the Hybrid Redemption Right is, in each case, expected to create tax attributes for HMH Inc. (and, with respect to any acquisition of Mercury HoldCo Inc. shares, allow HMH Inc. to share in existing tax attributes). These tax attributes would not have been available to HMH Inc. absent its acquisition or deemed acquisition of such B.V. Voting Shares and B.V. Non-Voting Shares (collectively, the “B.V. Shares”) and, if applicable, its acquisition of the Mercury HoldCo Inc. shares, and are expected to reduce the amount of cash tax that HMH Inc. and Mercury HoldCo Inc. would otherwise be required to pay in the future. In connection with the closing of this offering, we will enter into the Tax Receivable Agreement with the Principal Stockholders, which will generally provide for the payment by us to the Principal Stockholders of 85% of the net cash savings, if any, in U.S. federal, state, local and foreign income tax and franchise tax that we actually realize (or are deemed to realize in certain circumstances) in periods after this offering as a result of those tax attributes, as well as the additional tax attributes created by payments under the Tax Receivable Agreement. We will retain the benefit of the remaining 15% of these cash savings. See “Risk factors—Risks related to this offering and ownership of our Class A common stock” and “Certain relationships and related party transactions—Tax Receivable Agreement.”

For definitions of Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow and Adjusted ROCE and reconciliations to their most directly comparable financial measures calculated and presented in accordance with GAAP, see “—Non-GAAP financial measures.”

(2)

Calculated as a percentage of revenue.

Non-GAAP financial measures

Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, EBITA and Adjusted ROCE (each as defined herein) are non-GAAP financial measures and should not be considered alternatives to, or more meaningful than, net income, net income as a percentage of revenue, net cash provided by operating activities, net income as a percentage of total assets or any other measure presented in accordance with GAAP. Our computation of Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, EBITA and Adjusted ROCE may differ from computations of similarly titled measures of other companies. For a reconciliation of these non-GAAP measures to the most directly comparable GAAP measures, please see below.

Adjusted EBITDA and Adjusted EBITDA Margin

We use Adjusted EBITDA and Adjusted EBITDA Margin (each, a non-GAAP measure) as one of the indicators to evaluate and compare the results of our operations from period to period by removing the effect of our capital structure and certain non-recurring items. We define Adjusted EBITDA as net income before interest expense, net, income tax expense, depreciation and amortization and certain non-recurring items that we do not consider to be indicative of our ongoing operating performance such as, but not limited to, IT system implementation, restructuring expenses and foreign currency transaction (gain) loss. We track Adjusted EBITDA on an absolute dollar basis and as a percentage of revenue, which we refer to as Adjusted EBITDA Margin. We

define Adjusted EBITDA Margin as Adjusted EBITDA divided by revenue. We believe that Adjusted EBITDA is a supplemental measurement tool used by analysts and investors to evaluate overall operating performance, ability to pursue and service possible debt opportunities and possible future investment opportunities. In addition, we believe that Adjusted EBITDA Margin is a supplemental measurement tool used by analysts and investors to evaluate profitability of sales. Adjusted EBITDA does not represent funds available for our discretionary use and is not intended to represent or to be used as a substitute for net income, as measured under GAAP. The items excluded from Adjusted EBITDA and Adjusted EBITDA Margin, but included in the calculation of reported net income, are significant components of the consolidated statements of income and must be considered in performing a comprehensive assessment of overall financial performance.

The following table presents a reconciliation of the GAAP financial measure of net income to Adjusted EBITDA and Adjusted EBITDA Margin for each of the periods indicated:

Free Cash Flow

We use Free Cash Flow (a non-GAAP measure) to evaluate our liquidity to provide flexibility and optionality to achieve our broader capital allocation strategy. We define Free Cash Flow as cash flow from operations minus purchases of property and equipment and development costs. We believe that Free Cash Flow is a meaningful indicator of liquidity that provides information to our management and investors about the amount of cash generated from operations, after purchases of property and equipment that can be used for investment in our business and for acquisitions as well as to strengthen our balance sheet. Free Cash Flow has limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of other GAAP financial measures, such as net cash provided by operating activities. Free Cash Flow does not reflect our ability to meet future contractual commitments and may be calculated differently by other companies in our industry, limiting its usefulness as a comparative measure.

The following table presents a reconciliation of the GAAP financial measure of net cash provided by operating activities to Free Cash Flow for each of the periods indicated:

Development costs consist of charges related to the upgrade of our Enterprise Resource Planning software, coupled with internally developed software costs that will have alternative uses for our ongoing business.

Adjusted ROCE

We use Adjusted ROCE (a non-GAAP measure) to evaluate the profitability of the Company’s capital employed in its business operations compared with that of its peers. We define Adjusted ROCE as net income plus interest expense, net, income tax expense and amortization expense for intangible assets, which we refer to as EBITA (a non-GAAP measure), divided by total assets less goodwill, other intangibles and total current liabilities. We believe Adjusted ROCE is a good indicator of long-term company and management performance as it relates to capital efficiency.

You should carefully consider the risks described below, together with the other information in this prospectus, before deciding whether to purchase our Class A common stock. If any of the risks described below actually occur, our business, financial condition, results of operations or prospects could be materially adversely affected. In any such case, the trading price of our Class A common stock could decline, and you could lose all or part of your investment.

Risks related to our business

We generate substantial revenues from companies involved in oil and natural gas exploration and production, an industry known for its cyclical nature, with levels of activity that are directly affected by the fluctuating levels and volatility of oil and natural gas prices.

The demand for our products and services depends, in large part, on the demand for, and production of, oil and natural gas. In particular, demand for our products and services depends, in large part, on capital investment in offshore drilling. Oil and natural gas are commodities and, therefore, their prices are subject to wide fluctuations in response to relatively minor changes in supply and demand. Supply and demand for oil and natural gas are dependent upon a variety of factors, many of which are beyond our control. These factors include the following:

•

worldwide demand of oil and gas, including economic activity in the United States, other large energy consuming markets and in developing energy markets;

•

the action of OPEC, its members and other state-controlled oil companies relating to oil price and production controls;

•

the level of production in non-OPEC countries;

•

delay and regulatory uncertainty stemming from federal or local governmental or environmental (including non-governmental organization) opposition to offshore and onshore energy development projects;

•

the cost of exploring for, producing and delivering oil and natural gas;

•

the discovery rate, size and location of new oil and natural gas reserves, including in offshore areas;

•

the rate of decline of existing oil and natural gas reserves due to production;

•

laws and regulations related to environmental matters, including those addressing alternative energy sources and the risks of global climate change;

•

the development, exploitation and market acceptance of alternative fuels or energy sources and end-user conservation trends;

•

domestic, local and foreign governmental regulation, moratoriums on drilling, taxes, tariffs and economic sanctions;

•

technological advances, including technology related to the exploitation of shale oil, which can result in over-supply of oil and natural gas or a change in demand for oil and natural gas;

•

global or national health concerns, including health epidemics or pandemics such as the COVID-19 pandemic;

•

contractions in the credit market;

•

cost and availability of storage and transportation of oil, gas and related products;

•

inventory levels of oil, gas and related products;

•

accidents, adverse weather conditions, natural disasters and other similar incidents relating to the oil and gas industry;

•

uncertainty in commodities markets;

•

acquisition and divestiture activity among oil and natural gas producers;

•

competition among oilfield service and equipment providers;

•

the ability of oil and natural gas producers to generate funds for their capital-intensive businesses, including via their ability to raise equity capital and debt financing;

•

rough seas and adverse weather conditions, including hurricanes and typhoons;

•

expectations regarding future energy prices; and

•

worldwide financial instability or recessions.

Prices for oil and natural gas have historically been, and we anticipate they will continue to be, volatile and reactive to changes in the supply of and demand for oil and natural gas, domestic and worldwide economic conditions and political instability in oil producing countries. In particular, oil prices fluctuated during 2018 and 2019, and declined dramatically during 2020 due to the decline in demand caused by COVID-19 and associated lockdowns, dropping to $9.12 per barrel of Brent crude oil on April 21, 2020. Oil prices steadily increased significantly in 2021 and the first half of 2022 due to increased demand, domestic supply reductions, OPEC control measures and market disruptions resulting from the Russia-Ukraine war and sanctions on Russia. Since the Russia-Ukraine conflict first commenced, Brent crude oil prices have been volatile, reaching a high of $112.24 per barrel in June 2022 before declining to $65.28 per barrel as of May 12, 2025. Natural gas prices reached a high of $9.68 per MMbtu in August 2022 before declining to $3.19 per MMbtu as of May 12, 2025. Any substantial decline in oil and natural gas prices will likely have an adverse effect on demand for our products and services, and any decreases, over a sustained period of time, could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We face competition that may cause us to lose market share.

The oilfield services industry is highly competitive. The principal competitive factors impacting sales of our products and services are price, technology, service quality and safety track record. The market is also fragmented and includes numerous small companies capable of competing effectively in our markets on a local basis, especially in the onshore oil and gas market, as well as several large companies that possess substantially greater financial and other resources than we do, especially in the offshore oil and gas market. Our larger competitors’ greater resources could allow those competitors to compete more effectively than we can. For instance, our larger competitors may offer products at below-market prices or bundle ancillary products and services at no additional cost to customers. We compete with large national and multi-national companies that have longer operating histories, greater financial, technical and other resources and greater name recognition than we do. Some of our competitors provide a broader array of products and services, have a stronger presence in more geographic markets and may be able to respond more quickly to changes in customer requirements resulting from emerging technologies and services.

Most sales of products and projects are awarded on a bid basis, which further increases competition based on price. Pricing is one of the primary factors in determining which qualified contractor is awarded a job. The competitive environment may be further intensified by business combinations among oil and gas companies or other events that have the effect of reducing the number of available customers. If competition remains the same or increases as a result of future industry downturns, we may be required to lower our prices, which would adversely affect our results of operations. In the future, we may lose market share or be unable to maintain or increase prices for our present products and services or to acquire additional business opportunities, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We depend on suppliers and we may become subject to product shortages, long lead times and price increases, which could have a negative impact on our results of operations.

Our business relies on a broad range of raw materials and commodities for the products we manufacture. Shortages and transportation and supply disruptions can adversely impact supply of our manufacturing raw materials, as well as delivery of finished goods and transportation of our personnel for services. If we are unable to purchase raw materials for our products on a timely basis to meet the demands of our customers, our existing customers may, under certain circumstances (such as excessive delays) and pursuant to certain contractual provisions, be able to claim liquidated damages or terminate their contractual relationships with us, or we may not be able to compete for business from new or existing customers, which, in each case, could have a material adverse effect on our business, financial condition, results of operations and cash flows. Further, supply chain bottlenecks, such as those experienced as a result of the COVID-19 pandemic, could adversely affect our ability to obtain necessary materials, parts or other components used in our operations or increase the costs of such items. A significant increase in the price of such equipment, materials and services, as a result of supply chain and logistics disruptions or otherwise, could have a negative impact on our business, financial condition, results of operations and cash flows.

Most of the raw materials and components used in our operations are supplied by certain key vendors. Our reliance on these suppliers involves several risks, including price increases and a potential inability to obtain an adequate supply of required components in a timely manner. Weak economic conditions or widespread financial distress could reduce the liquidity of our suppliers or vendors, making it more difficult for them to meet their commitments or obligations to us. Nonperformance by suppliers or vendors who have committed to provide us with critical products or services could raise our costs, interfere with our ability to successfully conduct our business or have a negative impact on our business, financial condition, results of operations and cash flows. We do not have long-term contracts for raw materials or component parts with certain of these suppliers, and a partial or complete loss of any of these sources could have a negative impact on our results of operations and could damage our customer relationships. In addition, the preferences of our customers with respect to particular vendors may change, which could require us to find new vendors.

We depend on a limited number of customers.

We depend on a limited number of significant customers. Our top five customers accounted for approximately 52.0%, 42.0% and 32.9% of our total consolidated revenues for the three months ended March 31, 2025 and the years ended December 31, 2024 and 2023, respectively. During the three months ended March 31, 2025, three customers accounted for 14.4%, 12.3% and 11.9% of our revenues for such period, respectively, and during the year ended December 31, 2024, one customer accounted for 18.2% of our revenues for such year. The loss of business from one or more significant customers, or the failure to perform under any contract with such significant customers, could have a material adverse effect on our business, financial condition, results of operations and cash flows.

There are risks associated with certain contracts for our products and services.

As of March 31, 2025, we had a backlog of contracts in the amount of $464.2 million, of which $185.1 million was attributable to projects and products and $279.1 million was attributable to services. The following factors, among others, could reduce our margins on our contracts for the sale of products and services, adversely impact completion of these contracts, adversely affect our position in the market or subject us to contractual penalties:

•

financial challenges for consumers of our products and services;

•

failure to obtain timely payments from our customers, defaults on our customers’ payment obligations or disputes with customers involving such payment obligations;

•

credit market conditions for consumers of our products and services;

•

our failure to adequately estimate costs for making our products;

•

our inability to manufacture products that meet contracted technical requirements;

•

our inability to timely deliver finished goods;

•

our inability to transport our personnel for services;

•

our inability to maintain our quality standards during the design and manufacturing process;

•

our inability to secure parts made by third-party vendors at reasonable costs and within required timeframes;

•

unexpected increases in the costs of raw materials;

•

our inability to manage unexpected delays due to weather, shipyard access, labor shortages, public health crises such as the COVID-19 pandemic or other factors beyond our control;

•

inability or unwillingness of the customer to renew or sign additional contracts with us;

•

the imposition of tariffs, duties or economic sanctions, which could materially affect our global supply chain (e.g., steel tariffs under Section 232 of the Trade Expansion Act of 1962 (19 U.S.C. §1862), as amended, may increase our costs, reduce margins or otherwise adversely affect us); and

•

trade or travel restrictions, including export sanctions, trade controls or other supply chain interruptions, which could affect our ability to manufacture, sell or receive payment for our products or services.

Our existing contracts for products and services generally carry significant down payment and progress billing terms to facilitate the ultimate completion of these projects, and the majority do not allow customers to cancel projects for convenience. However, unfavorable market conditions or financial difficulties experienced by our customers have in the past and may in the future result in cancellation of contracts, the delay or abandonment of projects, unwillingness to enter into subsequent contracts and our inability to attract new customers. Additionally, some of our contracts allow for cancellation by the customer in the event of our insolvency or bankruptcy or a material uncured breach by us. Finally, some of our contracts include force majeure provisions where we or our customers are relieved, temporarily or sometimes permanently, of contractual obligations. Any such developments could have a material adverse effect on our operating results and financial condition.

We sometimes provide packages and other engineered products for multi-year, fixed price contracts that may require us to assume risks associated with cost over-runs, operating cost inflation, labor availability, supplier and contractor pricing and performance and potential claims for liquidated damages.

We sometimes provide packages of equipment or complex equipment in the form of multi-year contracts, without price escalation clauses. Some of these contracts are required by our customers, including national oil

companies. These projects include acting as suppliers of packages of equipment or engineered products, as well as installation and commissioning services and may require us to assume additional risks associated with cost over-runs from our vendors or due to material or labor cost escalation. In addition, national oil companies often possess substantial leverage in the event of dispute or disagreement regarding performance under an agreement and they often operate in countries with unsettled political conditions, war, civil unrest or other types of community issues. These issues may also result in cost over-runs, delays and project losses.

Providing packages of equipment and engineered products as well as services on an integrated basis may also require us to assume additional risks associated with operating cost inflation, labor availability and productivity, supplier pricing and performance and potential claims for liquidated damages. We rely on third-party subcontractors, consortium partners and equipment providers to assist us with the completion of these types of contracts. To the extent that we cannot engage subcontractors or acquire equipment or materials in a timely manner and on reasonable terms, our ability to complete a project in accordance with stated deadlines or at a profit may be impaired. If the amount we are required to pay for these goods and services exceeds the amount we have estimated in bidding for fixed-price work, we could experience losses in the performance of these contracts. These delays and additional costs may be substantial, and we may be required to compensate our customers for these delays. This may reduce the profit to be realized or result in a loss on a project.

Unionization efforts, labor interruptions and labor regulations could have a material adverse effect on our operations.

Certain of our employees and contractors in international markets, including Germany, Norway and Mexico, are represented by labor unions and work under collective bargaining or similar agreements, which are subject to periodic renegotiation. Although we have not experienced any labor disruptions, strikes or other forms of labor unrest in connection with our personnel, there can be no assurance that labor disruptions by employees and contractors will not occur in the future. Further, unionized employees of third parties on whom we rely may be involved in labor disruptions, strikes or other forms of labor unrest, causing operational disruptions. Such actions could result in the occurrence of additional costs, as well as limitations on our ability to operate or provide products and services to our customers, which may materially adversely affect our business, financial condition, results of operations and cash flows. In addition, strikes may occur in connection with any salary negotiations with respect to unionized employees or contractors. If future labor strikes force us to shut down any of our operations, such interruption in operations could materially adversely affect our business, financial condition, results of operations and cash flows.

Certain developments in the global oil and gas markets, such as the impacts we experienced from COVID-19, the Russian invasion of Ukraine and related sanctions, and the ongoing conflict in Gaza, the Red Sea and the surrounding region have had, and may continue to have, material adverse consequences for general economic, financial and business conditions, and could materially and adversely affect our business, financial condition, results of operations and cash flows and those of our customers, suppliers and other counterparties.

The outbreak of the COVID-19 pandemic in 2020 had significant global effects on demand for oil and gas and resulted in substantial reductions in demand for our products and services. While oil and gas prices and, therefore, demand for our products and services have largely recovered as the impacts of COVID-19 pandemic have been alleviated, concerns over the prolonged negative effects of the COVID-19 outbreak may persist. Such conditions have resulted in, and could again result in, reductions to our customers’ drilling and production expenditures and delays or cancellations of projects, thus decreasing demand for our products and services, and an increased risk that our customers may seek price reductions or more favorable economic terms for our products and services or terminate our contracts.

Beginning in 2014 and to a greater extent following Russia’s military action in Ukraine in 2022, the United States, the European Union (“EU”) and the United Kingdom, among others, have imposed significant economic

sanctions and export control measures on Russia and others supporting Russia’s military and political actions in Ukraine, including restrictions on the Russian energy and financial sectors, prohibitions and restrictions relating to Russian origin oil and oil products, and export controls limiting the export of a wide range of goods and technical assistance to Russia. In response, Russia has implemented certain counter-sanctions. Existing and future economic sanctions, export controls, import controls and other measures, including those that may be enacted by the Trump Administration, as well as the existing and potential further responses from Russia or other countries to such economic sanctions, and further tensions and military actions, could adversely affect the global economy and financial markets and could adversely affect our business, financial condition and results of operations.

Additionally, the ongoing conflict in Gaza, the Red Sea and the surrounding region, the Russian invasion of Ukraine and related sanctions have significantly disrupted supply chains for crude oil and natural gas in certain of the markets in which we operate. The Russia-Ukraine conflict and other geopolitical tensions, as well as the related international response, have exacerbated global supply chain disruptions, which have resulted in, and may continue to result in, shortages in materials and services and related uncertainties. Such shortages have resulted in, and may continue to result in, cost increases for labor, fuel, materials and services, and could continue to cause costs to increase and also result in the scarcity of certain materials. Any economic slowdown or recession in Europe or globally, including as a result of such supply chain disruptions or sanctions, may also impact demand and depress the price for crude oil, natural gas or other products, which could have significant adverse consequences on our financial condition and the financial condition of our customers, suppliers and other counterparties, and could diminish our liquidity. Further, the ongoing conflict in Gaza, the Red Sea and the surrounding region could escalate into a broader conflict in the Middle East that could further disrupt energy operations and supply chains globally.

Our operations may be impacted by changing macroeconomic conditions, including inflation.

Inflation has been an ongoing concern since 2021 and has continued into 2025. Ongoing inflationary pressures have resulted in, and may continue to result in, additional increases to the costs of goods, services and personnel, which in turn could cause our capital expenditures and operating costs to rise, as well as a scarcity of certain products and raw materials. Like others in our industry, in 2022, 2023 and 2024, we faced, and continue to face, considerable inflation in the cost of raw materials and personnel. International conflicts or other geopolitical events, such as the continuing Russia-Ukraine war and the ongoing conflict in Gaza, the Red Sea and the surrounding region, may also cause upward pressure on the cost of raw materials due to transportation disruptions, higher manufacturing costs, disruptions in supply chains and availability of raw materials, interruptions in manufacturing operations and heightened inflation. To the extent inflation remains elevated, we may experience further cost increases for our operations, as well as increased labor costs. Sustained levels of high inflation caused the U.S. Federal Reserve to raise its target range for the federal funds rate multiple times in 2022 and 2023, but the U.S. Federal Reserve cut rates multiple times between September and December of 2024, resulting in a total aggregate increase of 425 basis points. The U.S. Federal Reserve’s target rate is currently between 4.25% and 4.50%. Future rate hikes from the U.S. Federal Reserve (or its equivalent in other nations) or other efforts to curb inflationary pressure on the costs of goods and services could have the effect of raising the cost of capital and depressing economic growth, either of which (or the combination thereof) could hurt the financial and operating results of our business.

High oil and natural gas prices are also inflationary, and governmental or economic responses to high oil and natural gas prices could impact the operations of our customers. Sustained high oil and natural gas prices could also drive over-investment and create the potential for global oversupply, which could cause prices to fall, also impacting investment by our customers.

Any future reduction in worldwide economic growth and economic activity could, if sustained, ultimately lead to a global recession. In a global recession, it is likely that the demand for oil and natural gas would decline and the number of planned offshore energy projects would decrease. Such a scenario would negatively impact the demand for our products and services and, in turn, our financial performance.

A deterioration in global economic conditions and adverse developments affecting the financial services industry could affect our current and projected business operations and our financial condition and results of operations.

Our results of operations are materially affected by conditions in the global capital markets and the economy generally, both in the United States and elsewhere around the world. Weak economic conditions, sustained uncertainty about global economic conditions or a prolonged or further tightening of credit markets could cause our customers and potential customers to postpone or reduce spending on products or services or put downward pressure on prices, which could have an adverse effect on our business, financial condition, results of operations and cash flows. In the event of extreme prolonged adverse market events, such as a global credit crisis, we could incur significant losses. The future impact of these types of events on our business, financial condition, results of operations and cash flows depends largely on developments outside our control.

Our access to funding sources and other credit arrangements in amounts adequate to finance our current and projected future business operations could be significantly impaired by factors that affect us, any financial institutions with which we enter into credit agreements or arrangements directly, or the financial services industry or economy in general. These factors could include, among others, events such as liquidity constraints or failures affecting financial institutions, the ability of financial institutions to perform obligations under various types of financial, credit or liquidity agreements or arrangements or disruptions or instability in the financial services industry or financial markets.

The results of events or concerns that involve one or more of these factors could include a variety of material adverse effects on our current and projected business operations, financial condition and results of operations. These risks include, but may not be limited to, the following:

•

delayed access to deposits or other financial assets or the uninsured loss of deposits or other financial assets;

•

inability to enter into credit facilities or other working capital resources;

•

potential or actual breach of contractual obligations that require us to maintain letters of credit or other credit support arrangements; or

•

termination of cash management arrangements or delays in accessing or actual loss of funds subject to cash management arrangements.

In addition, investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, refusal to refinance existing indebtedness upon its maturity or on terms similar to the expiring debt or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all. Any decline in available funding or access to our cash and liquidity resources could, among other risks, adversely impact our ability to meet our operating expenses or other obligations, financial or otherwise, result in breaches of our financial or contractual obligations or could result in temporary violations of international, federal or state wage and hour laws.

Any of these impacts, or any other impacts resulting from the factors described above or other related or similar factors, could have material adverse effects on our liquidity and our current and projected business operations and financial condition and results of operations. In addition, deterioration in the macroeconomic

economy or financial services industry could lead to losses or defaults by our partners, vendors or suppliers, which in turn could have a material adverse effect on our current and projected business operations, results of operations and financial condition.

The default by customers and counterparties could adversely affect our business, financial condition, results of operations and cash flows.

The deterioration in the financial condition of one or more of our significant customers or counterparties could result in their failure to perform under the terms of their agreements with us or default in payments owed to us. Our customers and counterparties include crude oil and natural gas E&P companies, drilling contractors, equipment and raw material suppliers, shipyards and manufacturers of capital equipment whose creditworthiness may be suddenly and disparately impacted by, among other factors, commodity price volatility, deteriorating energy market conditions and public and regulatory opposition to energy producing activities. Additionally, we depend on a limited number of customers for a significant portion of our revenues. Our top five customers accounted for approximately 52.0%, 42.0% and 32.9% of our total consolidated revenues for the three months ended March 31, 2025 and the years ended December 31, 2024 and 2023, respectively. During the three months ended March 31, 2025, three customers accounted for 14.4%, 12.3% and 11.9% of our revenues for such period, respectively, and during the year ended December 31, 2024, one customer accounted for 18.2% of our revenues for such year. As a result of the volatility in the commodity market and the depressed prices for oil and natural gas following the emergence of COVID-19, some of our customers have undergone Chapter 11 bankruptcy or other reorganization procedures within the past five years. During such bankruptcies, we were considered a critical vendor and suffered only minor delays and discounts on payment collections, but we may not be considered a critical vendor in the event of any customer bankruptcies in the future.

The concentration of credit risk may be affected by changes in economic or other conditions within our industry and may accordingly affect our overall credit risk. While we have credit approval procedures and policies in place, we are unable to completely eliminate the performance and credit risk to us associated with doing business with these parties. In a low commodity price environment, certain of our customers have been or could be negatively impacted, causing them significant economic stress, resulting, in some cases, in a customer bankruptcy filing or an effort to renegotiate our contracts. The deterioration in the creditworthiness of our customers and the resulting increase in nonpayment or nonperformance by them could cause us to write down or write off accounts receivables or tangible and intangible assets. Such write-downs or write-offs could negatively affect our operating results in the periods in which they occur, and, if significant, could have a material adverse effect on our business, financial condition, results of operations and cash flows. To the extent one or more of our key customers commences bankruptcy proceedings, our contracts with the customers may be subject to rejection under applicable provisions of the United States Bankruptcy Code or, if we so agree, may be renegotiated. Further, during any such bankruptcy proceeding, prior to assumption, rejection or renegotiation of such contracts, the bankruptcy court may temporarily authorize the payment of value for our services less than contractually required, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. The resolution of our outstanding claims against such a customer or counterparty is dependent on the terms of the plan of reorganization but may include our claims being converted to equity in the reorganized entity and in addition to impacting our business, financial condition, results of operations and cash flows could require us to incur impairment charges against the associated assets or write down our goodwill.

Our estimates of market potential and forecasts of market growth may prove to be inaccurate.

Market estimates and growth forecasts, including those of Rystad Energy, the IEA and our management, are uncertain and based on assumptions and estimates that may be inaccurate. The extent of our potential market size and growth depends on a number of factors, including changes in the competitive landscape, technological

changes, customer budgetary constraints, changes in business practices, changes in the regulatory environment, changes in economic conditions, oil and gas activity levels and the price we can charge for our products and services. Our estimates relating to the extent of our potential market size and growth may prove to be inaccurate. Even if the markets in which we compete meet the size estimates and growth rates we estimate or forecast, our business could fail to grow at similar rates, if at all, which could cause the trading price of our Class A common stock to decline or be volatile.

The growth of our business through recent and potential future acquisitions may expose us to various risks, including those relating to difficulties in identifying suitable acquisition opportunities and integrating businesses, assets and personnel, as well as difficulties in obtaining financing for targeted acquisitions and the potential for increased leverage or debt service requirements.

We intend to pursue selected acquisitions of complementary assets and businesses, such as the Drillform Acquisition. The success of this strategy is dependent upon our ability to identify appropriate acquisition targets, negotiate transactions on favorable terms, finance transactions, obtain necessary regulatory approvals, complete transactions and successfully integrate them into our existing business. Acquisitions involve numerous risks, including:

•

unanticipated costs and exposure to liabilities assumed in connection with the acquired business or assets, including, but not limited to, environmental liabilities and title issues;

•

difficulties in integrating the operations and assets of the acquired business and any acquired personnel;

•

complexities associated with managing a larger, more complex, integrated business;

•

limitations on our ability to properly assess and maintain an effective internal control environment over an acquired business;

•

potential losses of key employees, customers and business partners of the acquired business;

•

performance shortfalls at one or both of the companies as a result of the diversion of management’s attention from their day-to-day responsibilities caused by completing an acquisition and integrating an acquired business into the combined company;

•

risks of entering markets in which we have limited prior experience; and

•

increases in our expenses and working capital requirements.

The process of integrating an acquired business may involve unforeseen costs and delays or other operational, technical and financial difficulties, and may require a significant or disproportionate amount of time and managerial and financial resources. We may experience difficulties in integrating recent and future acquired businesses’ operations into our business and in realizing expected benefits and synergies from such acquisitions. If we are unable to successfully integrate the operations of recent and future acquired businesses with our business, we may be unable to achieve consolidation savings and may incur unanticipated costs and liabilities.

Our failure to incorporate acquired businesses and assets into our existing operations successfully or to minimize any unforeseen operational difficulties could have a material adverse effect on our business, liquidity position, financial condition, prospects and results of operations. Furthermore, competition for acquisitions may increase the cost of, or cause us to refrain from, completing acquisitions.

In addition, we may not have sufficient capital resources to complete any additional acquisitions. Historically, we have financed our acquisitions with a combination of cash generated from operations, borrowings, performance-

based deferred payments and debt issuances. Subject to the terms of our indebtedness, we may incur substantial indebtedness to finance future acquisitions, may issue equity, debt or convertible securities in connection with such acquisitions and may incur performance-based deferred payments. Debt service requirements could represent a significant burden on our results of operations and financial condition, and the issuance of additional equity or convertible securities could be dilutive to our existing stockholders. Furthermore, we may not be able to obtain additional financing as needed or on satisfactory terms.

Our ability to grow through acquisitions and manage growth will require us to continue to invest in operational, financial and management information systems and to attract, retain, motivate and effectively manage our employees. The inability to effectively manage the integration of acquisitions could reduce our focus on current operations, which, in turn, could negatively impact our earnings and growth. Our financial position and results of operations may fluctuate significantly from period to period, based on whether or not significant acquisitions are completed in particular periods.

We are subject to risks relating to existing international operations and expansion into new geographical markets.

We continue to focus on expanding sales globally as part of our overall growth strategy and expect sales from outside the United States to continue to represent a significant and growing portion of our revenue. Our international operations and global expansion strategy are subject to general risks related to such operations, including:

•

political, social and economic instability and disruptions;

•

social unrest, acts of terrorism, war and other armed conflict;

•

nationalization and expropriation;

•

public health crises and other catastrophic events, such as the COVID-19 pandemic;

•

export controls, economic sanctions, embargoes, import controls, duties and tariffs and other trade restrictions;

•

limitations on ownership and on repatriation or dividend of earnings;

•

transportation delays and interruptions;

•

labor unrest and current and changing regulatory environments;

•

increased compliance costs, including costs associated with disclosure requirements and related due diligence;

•

difficulties in staffing and managing multinational operations;

•

limitations on our ability to enforce legal rights and remedies;

•

access to or control of networks and confidential information due to local government controls and vulnerability of local networks to cybersecurity risks;

•

inflation;

•

changes in tax laws; and

•

fluctuations in foreign currency exchange rates.

If we are unable to successfully manage the risks associated with expanding our global business or adequately manage operational risks of our existing international operations, these risks could have a material adverse effect on our growth strategy into new geographical markets, our reputation and our business, financial condition, results of operations and cash flows.

We must comply with export and import controls, economic sanctions and embargoes and other international trade laws and regulations, and any failure to comply with such laws and regulations could subject us to liability and have a material adverse impact on our business, financial condition and results of operations.

We conduct business globally, and our business activities and services must be conducted in compliance with applicable import and export control laws and regulations, as well as economic sanctions and other international trade laws of the United States, the EU, the United Kingdom, Norway and other countries. The export and import controls, economic sanctions, embargoes and other international trade laws include the U.S. Commerce Department’s Export Administration Regulations, the U.K. Strategic Export Control List, the Norwegian Export Control Act, the Norwegian Export Control Regulation, economic sanctions regulations administered by the U.S. Department of the Treasury’s Office of Foreign Assets Control, the U.S. Department of State, the United Nations (“U.N.”) Security Council, the European Commission, competent authorities of EU Member States, the U.K.’s Office of Financial Sanctions Implementation and the Norwegian Ministry of Foreign Affairs and their equivalents in other countries where we operate. Although we have instituted and implemented policies and procedures reasonably designed to promote compliance with such laws and regulations, our global operations expose us to the risk of violating, or being accused of violating, import and export controls, economic sanctions, embargoes and other international laws and regulations. Violation of import or export control laws and regulations or economic sanctions, embargoes or other international trade laws could result in negative consequences to us, including government investigations, sanctions, criminal or civil fines or penalties, more onerous compliance requirements, loss of authorizations or licenses needed to conduct aspects of our business, default under debt, reputational harm and other adverse consequences. Moreover, if any of our counterparties or jurisdictions where we do business becomes the target of economic sanctions, we may face an array of issues, including, but not limited to, having to abandon the related project, being unable to recoup prior invested time and capital or being subject to lawsuits, investigations or regulatory proceedings that could be time consuming and expensive to respond to, and which could lead to criminal or civil fines or penalties. For example, in compliance with applicable trade restrictions relating to Russia, we withdrew all operations in and sales into Russia and no longer support our equipment installed in Russia, and there are various other regions where we refrain from making sales of our products and services. Furthermore, the laws and regulations concerning import activity, export recordkeeping and reporting, export control and economic sanctions are complex and constantly changing. These laws and regulations can cause delays in shipments, unscheduled operational downtime and material impacts to our business operations. Despite our compliance efforts, we cannot assure compliance by our employees or representatives for which we may be held responsible, and any such violation could materially adversely affect our reputation, business, financial condition and results of operations.

The results of our operations are subject to market risk from changes in foreign currency exchange rates.

Our non-U.S. operations generate significant revenues and earnings, and we pay expenses, purchase assets, source raw materials and incur liabilities in countries using currencies other than the U.S. dollar, including, but not limited to, the Euro (“EUR”), the British pound sterling and the Norwegian krone (“NOK”). During 2024 and the three months ended March 31, 2025, 63.9% and 66.9%, respectively, of our revenue was derived from sales outside the United States. Because our financial statements are presented in U.S. dollars, we must translate revenues and expenses into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Thus, increases or decreases in the value of the U.S. dollar against other currencies in which our operations are conducted will affect our revenue and operating income. Because of the geographic diversity of our operations, weaknesses in some currencies might be offset by strengths in others over time. Additionally, fluctuations in

foreign currency exchange rates may affect product demand and may adversely affect the profitability in U.S. dollars of the products we provide in international markets where payment for our products is made in the local currency. We use derivative financial instruments to mitigate our net exposure to currency exchange fluctuations. We had forward contracts with a notional amount of $144.1 million (with a fair value of a net asset of $1.1 million) as of March 31, 2025, to reduce the impact of foreign currency exchange rate movements. We are also subject to risks that the counterparties to these contracts fail to meet the terms of our foreign currency contracts. We cannot assure you that fluctuations in foreign currency exchange rates would not affect our financial results.

Policy changes affecting international trade could adversely impact the demand for our products and our competitive position.

Changes in government policies on foreign trade and investment can affect the demand for our products and services, impact the competitive position of our products and services or prevent us from being able to sell products and services in certain countries. Our business benefits from free trade agreements, and efforts to withdraw from or substantially modify such agreements, in addition to the implementation of more restrictive trade policies, such as more detailed inspections, higher tariffs, import or export licensing requirements, economic sanctions, anti-boycott laws, exchange controls or new barriers to entry, could have a material adverse effect on our business, financial condition, results of operations and cash flows. For example, we are already experiencing increased tariffs on certain of our products and product components from China. In addition, in April 2025, the Trump Administration announced a baseline tariff of 10% on products imported from all countries and an individualized reciprocal tariff on the countries with which the United States has the largest trade deficits. Increased tariffs by the United States have led and may continue to lead to the imposition of retaliatory tariffs by foreign jurisdictions. Such tariffs and any retaliatory tariffs may put upwards pressure on prices in other jurisdictions from which we purchase product components, which could reduce our ability to offer competitive pricing to potential customers and affect the demand for our products. Additionally, the Trump Administration has announced and rescinded multiple tariffs on several foreign jurisdictions, which has increased uncertainty regarding the ultimate effect of the tariffs on economic conditions.

We cannot predict what changes to trade policy will be made by the Trump Administration, the U.S. Congress or other governments, including whether existing tariff policies will be maintained or modified 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 or the global economy. Changes in U.S. trade policy, or threat of such changes, 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 or import products or product components from countries where we currently purchase products or product components or sell products or services. Such changes, or threatened changes, to 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, financial condition, results of operations and liquidity.

Equipment failures or production curtailments or shutdowns at our manufacturing and production facilities could adversely affect our manufacturing capability.

Our manufacturing capacity is subject to equipment failures and the risk of catastrophic loss due to unanticipated events, such as fires, explosions and adverse weather conditions. Our manufacturing processes depend on critical pieces of equipment. Such equipment may, on occasion, be out of service as a result of unanticipated failures, which could require us to close part or all of the relevant manufacturing and production facility or cause us to reduce production on one or more of our product lines. Any interruption in manufacturing capability may require us to make significant and unanticipated capital expenditures to effect repairs, which could have a negative effect on our profitability and cash flows. We carry business interruption insurance; however, recoveries under insurance coverage that we currently maintain or may obtain in the future may not

be sufficient to completely offset the lost revenues or increased costs resulting from a disruption of our operations. See “—We may not have adequate insurance for potential environmental, product or personal injury liabilities.” A sustained disruption to our business could also result in delays to or cancellations of customer orders and contractual penalties, which may also negatively impact our reputation among our customers. Any or all of these occurrences could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The loss of senior management or technical personnel could materially adversely affect our operations.

We depend on the services of our senior management and technical personnel. In particular, we depend on our current senior management for the implementation of our strategy and the supervision of our day-to-day activities. We do not maintain, nor do we plan to obtain, any insurance against the loss of any of these individuals. We have employment agreements with our senior executives that contain restrictions on competition with us in the event they cease to be employed by us. However, as a practical matter, such employment agreements may not assure the retention of our key employees and may not be enforceable. The loss of the services of our senior management or technical personnel, or an inability to attract and retain additional senior management or technical personnel, could have a material adverse effect on our business, financial condition and results of operations.

Many of our products are mechanically complex and often must perform in extremely challenging conditions. The design and delivery of our products and the performance of our services require skilled and qualified technical personnel with specialized skills and experience, and our ability to be productive and profitable will depend upon our ability to employ and retain skilled workers. The demand for skilled workers is high, and the supply is limited. As a result, competition for experienced personnel is intense, and we face significant challenges in competing for employees and management with large and well-established competitors. There is a greater shortage of skilled workers in some regions where we operate, such as Brazil. Additionally, we are subject to local content laws in jurisdictions where we operate, including certain countries in West Africa. Noncompliance could result in monetary fines and other penalties that may restrict our ability to operate in such countries. A significant increase in the wages paid by competing employers could result in a reduction of our skilled labor force, increases in the wage rates that we must pay or both. If either of these events were to occur, our cost structure could increase, and our operations and growth potential could be impaired. Employee turnover may also lead to lost productivity and decrease employee engagement, which could adversely impact our business.

We may incur liabilities to customers as a result of warranty claims that could adversely affect our reputation, ability to obtain future business and earnings.

We provide warranties as to the proper operation and conformance to specifications of the products we manufacture or install. Failure of our products to operate properly or to meet specifications may increase costs by requiring additional engineering resources and services, replacement of parts and equipment or monetary reimbursement to a customer. We have in the past received warranty claims, and we expect to continue to receive them in the future. To the extent that we incur substantial warranty claims in any period, our reputation, ability to obtain future business and earnings could be adversely affected.

Our operations and our customers’ operations are subject to unforeseen interruptions and hazards inherent in the oil and natural gas industry, for which we or our customers may not be adequately insured and which could cause us to lose customers and substantial revenue.

Our operations and our customers’ operations are exposed to the risks inherent to our industry, such as equipment defects, vehicle accidents, fires, explosions, blowouts, surface cratering, uncontrollable flows of gas or well fluids, pipe or pipeline failures, abnormally pressured formations and various environmental hazards, such as oil spills and releases of, and exposure to, hazardous substances. In addition, our operations and our

customers’ operations are exposed to potential natural disasters, including blizzards, tornadoes, wildfires, storms, floods, other adverse weather conditions and earthquakes. The occurrence of any of these events could result in substantial losses to us or our customers due to injury or loss of life, severe damage to or destruction of property, natural resources and equipment, pollution or other environmental damage, clean-up responsibilities, regulatory investigations and penalties or other damage resulting in curtailment or suspension of our operations or our customers’ operations. The cost of managing such risks may be significant. The frequency and severity of such incidents may affect operating costs, insurability and relationships with customers, employees and regulators. Our existing and potential future customers may elect not to purchase our products and services if they view our environmental or safety record as unacceptable, which could cause us to lose customers and substantial revenues. While we maintain a portfolio of insurance policies, our insurance may not be adequate to cover all losses or liabilities we may suffer. See “—We may not have adequate insurance for potential environmental, product or personal injury liabilities.”

As a designer, manufacturer, installer and servicer of oil and gas pressure control equipment, we may be subject to liability (including for environmental contamination), personal injury, property damage and environmental contamination should such equipment fail to perform to specifications.

We provide products and systems to customers involved in oil and gas exploration, development and production, as well as in certain other non-oil and gas markets. Some of our equipment is designed to operate in high-temperature or high-pressure environments on land, on offshore platforms and on the seabed. We also provide parts and services at numerous facilities located around the world, as well as at customer sites for this type of equipment. Because of applications to which our products and services are put, particularly those involving the high temperature or pressure environments, a failure of such equipment, or a failure of our customers to maintain or operate the equipment properly, could cause damage to the equipment, damage to the property of customers and others, personal injury and environmental contamination, onshore or offshore, leading to claims against us.

We may not have adequate insurance for potential environmental, product or personal injury liabilities.

While we maintain a portfolio of insurance policies to protect our core businesses against loss of property, business interruption, injury to personnel and liability to third parties for such losses as per industry standards, this insurance is subject to coverage limits. Certain types of losses are generally not insured by us because they are either uninsurable or not economically insurable, such as losses caused as a result of inability to deliver on time or at the right quality, or losses occasioned by willful misconduct, criminal acts, fines and penalties and various perils associated with war and terrorism. In addition, certain policies do not provide coverage for damages resulting from environmental contamination or may exclude coverage for other reasons. We face the following risks with respect to our insurance coverage:

•

we may not be able to maintain or obtain insurance of the type and amount we desire on commercially reasonable terms;

•

market conditions may cause premiums and deductibles for certain of our insurance policies to increase;

•

we may be faced with types of liabilities that will not be covered by our insurance;

•

our insurance carriers may not be able to meet their obligations under the policies; or

•

the dollar amount of any liabilities may exceed our policy limits or sub-limits.

An uninsured loss, a loss that exceeds the limits of our insurance policies or a succession of such losses could have a material adverse effect on our business, operations and financial condition. Even a partially uninsured

claim, if successful and of significant size, could have a material adverse effect on our consolidated financial statements. In addition, we may not be able to secure additional insurance or bonding that might be required by new governmental regulations. This may cause us to restrict our operations, which might severely impact our financial position.

Our limited combined historical financial statements may not be indicative of future performance.

HMH B.V. was formed in October 2021, through the combination of Baker Hughes’s Subsea Drilling Systems pressure control business and Akastor’s MHWirth drilling equipment business, and have a limited combined operating history. Additionally, due to the demand for our products and services depending, in large part, on the highly fluctuating and cyclical demand for, and production of, oil and natural gas, comparisons of our current and future operating results with prior periods are difficult. As a result, our limited combined historical financial performance may make it difficult for stockholders to evaluate our business and results of operations to date and to assess our future prospects and viability. As a public company, our cost structure will be different and will include both additional recurring costs and non-recurring costs that we will incur during our transition to being a public company. Accordingly, our historical consolidated financial information may not be reflective of our financial position, results of operations, cash flows or costs had we been a public company during the periods presented, and the historical financial information may not be a reliable indicator of what our financial position, results of operations or cash flows will be in the future. See “Management’s discussion and analysis of financial condition and results of operations.”

A terrorist attack or armed conflict could harm our business.

Terrorist activities, anti-terrorist efforts and other armed conflicts involving the United States or other countries may adversely affect the United States and global economies and could prevent us from meeting our financial and other obligations. If any of these events occur, the resulting political instability and societal disruption could reduce overall demand for oil and natural gas, potentially putting downward pressure on demand for our services and causing a reduction in our revenue. Oil and gas related facilities could also be direct targets of terrorist attacks, and our operations could be adversely impacted if infrastructure integral to our customers’ operations is destroyed or damaged. Costs for insurance and other security may increase as a result of these threats, and some insurance coverage may become more difficult to obtain, if available at all.

Certain of our facilities are located in close proximity to the Gulf of Mexico and, as a result, are susceptible to damage by hurricanes and other tropical storms.

Hurricanes and other tropical storms and the threat thereof could result in the shutdown of operations in coastal regions, including the Gulf of Mexico, as well as operations within the path and the projected path of the hurricanes or tropical storms. A number of our facilities are located within close proximity of the coast of the Gulf of Mexico, such as two facilities in Houston, Texas, USA, one facility in Mobile, Alabama, USA and one facility in Veracruz, Mexico. Our results of operations could be negatively impacted in the event of a hurricane or other tropical storm in the Gulf of Mexico that strikes the coastline near our facilities.

Risks related to environmental and regulatory matters

Environmental liabilities could adversely affect our customers’ business, financial condition and results of operations, which in turn could have a negative impact on demand for our products and services.

The oil and natural gas business is subject to environmental hazards, such as oil spills, gas leaks, ruptures, fires and discharges of petroleum products and hazardous and other substances and historical disposal activities. These environmental hazards could expose our customers to material liabilities, such as for property damages, personal injuries, criminal fines and penalties or environmental remediation measures, including costs of

investigating and remediating contaminated properties. A variety of stringent laws and regulations govern the environmental aspects of our customers’ businesses and impose strict requirements for, among other things:

•

well drilling or workover, operation and abandonment;

•

handling, transporting and disposing of a variety of fluids and substances, including hydraulic fracturing fluids, such as produced water;

•

accidental spills or releases or oil or other hazardous substances, and the remediation thereof;

•

protection of natural resources, air, water, wetlands, soil, protected species and protected areas;

•

seismic activity;

•

chemical use and storage;

•

financial assurance; and

•

controlling air emissions, preventing water contamination and unauthorized waste discharges.

Our business and our customers’ businesses are subject to complex laws and regulations that can adversely affect the cost, manner or feasibility of doing business.

Our operations are subject to extensive international conventions and treaties, as well as U.S. federal, state and local laws and regulations, including complex environmental laws, occupational health and safety laws and moratoriums on drilling. We may incur substantial costs in order to maintain compliance with these existing laws and regulations. Failure to comply with these laws and regulations may also result in the suspension or termination of our operations and subject us to administrative, civil and criminal penalties. Future laws or regulations, any adverse changes in the interpretation of existing laws and regulations, inability to obtain necessary regulatory approvals or a failure to comply with existing legal requirements may harm our business, financial condition, results of operations and cash flows.

We or our customers may incur significant delays, costs and liabilities as a result of environmental and occupational health and safety laws and regulations. These delays, costs and liabilities could arise under a wide range of federal, regional, state and local laws and regulations relating to the generation, transportation and disposal of hazardous substances, waste disposal, air emissions, water discharges, remediation, restoration and reclamation of environmental contamination, including oil spill cleanup and well plugging and abandonment requirements, protection of endangered and other protected species and related matters. We are also subject to extensive regulation of worker health and safety. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, denial, modification or revocation of permits or other authorizations, imposition of cleanup and site restoration costs and liens and, in some instances, issuance of orders or injunctions limiting or requiring discontinuation of certain operations. Despite the Trump Administration’s stated opposition to some of these regulations and initiatives, individual states have the right to enforce their own laws and, in some cases, federal laws, independent of the federal government.

In January 2023, the EU enacted the Corporate Sustainability Reporting Directive (“CSRD”), which considerably expanded the scope of mandatory sustainability reporting to which certain EU companies are subject. The CSRD entered into effect for the first in-scope companies from January 1, 2024, and requires the reporting of significant amounts of sustainability or Environmental, Social and Governance (“ESG”) information, including for many companies Scope 1, Scope 2 and Scope 3 emissions and climate-related financial risks. On March 6, 2024, the SEC adopted a new set of rules that require a wide range of climate-related disclosures, including material climate-related risks, information on any climate-related targets or goals that are material to the registrant’s business,

results of operations or financial condition, Scope 1 and Scope 2 greenhouse gas (“GHG”) emissions on a phased-in basis by certain larger registrants when those emissions are material and the filing of an attestation report covering the same, and disclosure of the financial statement effects of severe weather events and other natural conditions, including costs and losses. Multiple lawsuits have been filed challenging the SEC’s new climate rules, which have been consolidated in the U.S. Court of Appeals for the Eighth Circuit. On April 4, 2024, the SEC issued an order staying the final rules until judicial review is complete. On March 27, 2025, the SEC voted to end the defense of the rules in the litigation. On April 4, 2025, a group of 18 intervenor-respondent states and the District of Columbia moved to hold the cases in abeyance until the SEC amends or rescinds the regulations, which motion was granted by the Eighth Circuit in an order issued on April 24, 2025. While the ultimate outcome of legal challenges and any resulting changes to the final rules are not yet known, we cannot predict the costs of implementation or any potential adverse impacts resulting from the rulemaking. To the extent this rulemaking is implemented, which is uncertain at this time, we could incur increased costs relating to the assessment and disclosure of climate-related risks, and we cannot predict how any information disclosed under the rules may be used by financial institutions or investors. We may face increased litigation risks, or limits or restrictions on our access to capital, related to disclosures made pursuant to the rule if finalized as proposed. While the SEC’s new climate rules may ultimately not be implemented, individual states may continue to impose climate-related disclosure mandates. In addition to the SEC climate-related rules, laws and regulations in some state jurisdictions, such as the California Climate Corporate Data Accountability Act and Climate-Related Financial Risk Act, impose obligations in future years to report GHG emissions. Calculation of some GHG emissions can involve uncertainty and lack precision because of the absence of reliable inputs or methods to perform such calculations. Accordingly, the California regulations and other similar regulations may give rise to litigation risk concerning the required disclosures.

The CSRD, adopted in 2023, has a much broader scope than the SEC’s new climate rules and requires in-scope companies to publish reports on how their business and value chains impact the environment and society, as well as the social and environmental risks and opportunities to which they are subject. The CSRD also includes the disclosure of Scope 3 emissions (which were left out of the final SEC climate rules), to the extent that climate change is determined to be a material topic for the Company as part of a double materiality assessment. We have begun implementing policies and procedures to comply with these expansive new requirements beginning in 2025 for financial periods beginning on or after January 1, 2024.

On July 25, 2024, the EU Corporate Sustainability Due Diligence Directive (“CS3D”) entered into force. The CS3D requires the use of risk-based due diligence to mitigate “adverse environmental and human rights impacts” in an in-scope company’s “chain of activities,” including certain activities of its business partners. The CS3D also mandates the adoption of climate transition plans. Nonetheless, the provisions of the CS3D will not take effect until at least July 26, 2027. France and Germany have also adopted laws requiring large companies to carry out human rights and environmental due diligence, while similar laws have been proposed in other EU Member States, such as Belgium, the Netherlands and Austria. Further, the Norwegian Transparency Act (“NTA”), which took effect on July 1, 2022, requires mapping actual and potential risks of adverse impacts on decent working conditions and human rights.

On February 26, 2025, the European Commission published a proposal involving, among other things, significant simplifications of the CSRD and the CS3D. For the CSRD, the European Commission’s proposal includes, among other things, a postponed application for certain companies, a reduced scope of companies covered, as well as revised reporting standards (ESRS). For the CS3D, the European Commission’s proposal includes, among other things, a postponed application for certain companies and less stringent requirements relating to due diligence and climate transition plans. On April 17, 2025, the proposed postponements relating to the obligations of the CSRD and the CS3D entered into force through Directive (EU) 2025/794, which requires EU member states to adopt the changes into domestic legislation by December 31, 2025 at the latest. For the other proposed simplifications of

the CSRD and the CS3D to enter into force, approval by the European Parliament and the Council of the European Union is needed. As of May 2, 2025, it is uncertain whether or not these simplifications will be approved.

Compliance with these climate disclosures and broader ESG rules and value chain-related rules could be costly and time-consuming. Such enhanced disclosure and value chain related requirements could accelerate the trend of certain stockholders and lenders restricting or seeking more stringent conditions with respect to their investments in certain carbon intensive sectors.

Laws and regulations protecting the environment have become more stringent in recent years, and may, in some circumstances, result in liability for environmental damage regardless of negligence or fault through a strict, joint and several liability scheme. Costs associated with compliance with these laws, defending against related claims, and any actual liabilities have been and will continue to be significant.

Additionally, changes in environmental laws or regulations, including laws relating to the emission of carbon dioxide and other GHGs or other climate change concerns, could require us to devote capital or other resources to comply with these laws and regulations. Thus, any changes in environmental laws and regulations or re-interpretation of enforcement policies that result in more stringent and costly pollution control equipment and operations, the occurrence of delays in the permitting or performance of projects or waste handling, storage, transport, disposal or remediation requirements could have a material adverse effect on our business, financial condition, results of operations and cash flows. These changes could also subject us to additional costs and restrictions, including increased fuel costs. Such changes in laws or regulations could increase costs of compliance and doing business for our customers and thereby decrease the demand for our services. Because our business depends on the level of activity in the offshore oil and gas industry, existing or future laws and regulations related to GHGs and climate change, including incentives to conserve energy or use alternative energy sources, could have a negative impact on our business if such laws and regulations reduce the worldwide demand for oil and gas or limit drilling opportunities for our customers, which in turn reduces demand for our products and services.

Our business may be subject to risks related to climate change, including physical risks such as increased adverse weather patterns and transition risks such as evolving climate change regulation, alternative fuel measures and mandates, shifting consumer preferences, technological advances and negative shifts in market perception towards the oil and natural gas industry and associated businesses, any of which could result in increased operating expenses and capital costs or decreased resources and adversely affect our financial results.

Climate change continues to attract considerable attention in the United States and internationally, including from regulators, legislators, companies in a variety of industries, financial market participants and other stakeholders. This focus, together with government grants, incentives and subsidies focused on alternative energy development, such as those contained in the Inflation Reduction Act of 2022 (the “IRA 2022”), and changes in consumer and industrial/commercial behavior, preferences and attitudes with respect to the generation and consumption of energy, petroleum products and the use of products manufactured with, or powered by, petroleum products, may in the long term result in (i) the enactment of additional climate change-related regulations, policies and initiatives (at the government, regulator, corporate and investor community levels), including alternative energy requirements, new fuel consumption standards, energy conservation and emissions reductions measures and responsible energy development, (ii) technological advances with respect to the generation, transmission, storage and consumption of energy (e.g., wind, solar and hydrogen power, smart grid technology and battery technology, and increasing efficiency) and (iii) increased availability of, and increased consumer and industrial/commercial demand for, alternative energy sources and products manufactured with, or powered by, alternative energy sources (e.g., electric vehicles and renewable residential and commercial power supplies).

Climate change legislation and regulatory initiatives may arise from a variety of sources, including international, national, regional and state levels of government and associated administrative bodies, seeking to monitor, restrict

or regulate existing emissions of GHGs, such as carbon dioxide and methane, as well as to restrict or eliminate future emissions. Restrictions on GHG emissions that may be imposed, or the adoption and implementation of regulations that require reporting of GHG emissions or other climate-related information or otherwise seek to limit GHG emissions (including carbon pricing schemes) from us or our customers, could adversely affect our business and the oil and gas industry. For example, in 2015, the U.N. Climate Change Conference in Paris resulted in an agreement (the “Paris Agreement”) to set a target of keeping global temperature increase to below 1.5°C of pre-industrial levels. To measure progress towards this target, the Paris Agreement requires the parties to complete a global stocktake, assessing members’ collective efforts and achievements in reducing GHG emissions and adapting to the impacts of climate change, every five years. On December 13, 2023, the 28th annual U.N. Climate Change Conference (“COP 28”) issued its first global stocktake, which calls on parties to contribute to transitioning away from fossil fuels, reduce methane emissions and increase renewable energy capacity, among other things, to achieve net zero by 2050. The Paris Agreement and other like international conventions and agreements are expected to result in additional laws and regulations or changes to existing laws and regulations, including energy conservation incentives, in the EU and other countries where we have a presence, and could have a material adverse effect on our business and the business of our customers.

In response to the growing concerns regarding the role of methane in climate change, the United States enacted the IRA 2022, which contains provisions that impose fees for excess methane emissions from oil and gas facilities and includes incentives for renewable energy development. Further, on December 2, 2023, during COP 28, the United States announced new stricter methane rules to reduce emissions from both new and existing oil and natural gas industry sources. The final rules revising the new source performance standards regulating GHGs and volatile organic compounds emissions for the Crude Oil and Natural Gas source category pursuant to the Clean Air Act were published on March 8, 2024, and the final rules implementing the waste emissions charge (the “Waste Emissions Charge”) were published on November 18, 2024. On March 14, 2025, however, President Trump signed a Joint Resolution of Disapproval under the Congressional Review Act to prohibit the Environmental Protection Agency’s (“EPA”) Waste Emissions Charge rules from taking effect. Further, on January 20, 2025, the Trump Administration issued an executive order that initiated the process to withdraw the United States from the Paris Agreement, mandated ending the United States’ financial commitments under the UN Framework Convention on Climate Change, and revoked the U.S. International Climate Finance Plan. In addition to the executive order mentioned above, as of January 25, 2025, the Trump Administration had issued a series of executive orders that signal a shift in the United States’ energy and climate change policies. Among other directives, such executive orders: (i) direct federal agencies to identify and exercise emergency authorities to facilitate conventional energy production, transportation and refining, and call for the use of emergency regulations to expedite energy infrastructure projects; (ii) promote energy exploration and production on federal lands and waters; (iii) mandate a review of existing regulations that may burden domestic energy development; and (iv) pause the disbursement of funds appropriated through the IRA 2022 and the Infrastructure Investment and Jobs Act. It is not possible to predict the impact of the Trump Administration on these climate and energy initiatives at this time. While the Trump Administration may seek to reverse some or all of the initiatives advanced by the Biden Administration, it is unknown whether such reversals will ultimately be successful, and these or additional changes in the future could impact our business and operations, and those of our customers.

Accordingly, our business and operations, and those of our customers, are subject to executive, regulatory, political and financial risks associated with onshore and offshore operations, petroleum products and the emission of GHGs. Any legislation or regulatory programs related to climate change could increase our costs and require substantial capital, compliance, operating and maintenance costs, reduce demand for petroleum and related marine transportation services, reduce our access to financial markets and create greater potential for governmental investigations or litigation.

The adoption of legislation or regulatory programs to reduce GHG emissions could require us or our customers to incur increased operating costs or acquire emissions allowances to comply with new regulatory requirements. Such regulatory initiatives could also stimulate demand for alternative forms of energy that do not rely on petroleum products and indirectly reduce demand for our products and services.

Litigation risks are also increasing as a number of entities have sought to bring suit against various oil and natural gas companies in state or federal court, alleging, among other things, that such companies created public nuisances by producing fuels that contributed to climate change or alleging that the companies have been aware of the adverse effects of climate change for some time but defrauded their investors or customers by failing to adequately disclose those impacts. Such litigation against us or our customers could reduce the demand for our products and services, which could have a material adverse effect on our business, financial condition and results of operations.

There are also increasing financial risks for fossil fuel producers as stockholders currently invested in fossil fuel energy companies may elect in the future to shift some or all of their investments into non-fossil fuel related sectors. Institutional lenders who provide financing to fossil fuel energy companies also have become more attentive to sustainable lending practices, and some of them may elect not to provide funding for fossil fuel energy companies. There is also a risk that financial institutions will be required to adopt policies that have the effect of reducing the funding provided to the fossil fuel sector. Limitation of investments in and financing for fossil fuel energy companies could result in the restriction, delay or cancellation of drilling programs or development or production activities, which could reduce the demand for our products and services and have a material adverse effect on our business, financial condition and results of operations.

Fuel conservation measures, alternative fuel requirements, increasing consumer demand for alternatives to oil and natural gas, technological advances in fuel economy and energy generation devices, and the increased competitiveness of and technological advances with respect to alternative energy sources (such as electric vehicles, wind, solar, geothermal, tidal, fuel cells and biofuels), could reduce demand for oil and natural gas, resulting in reduced demand for oilfield services. The impact of the changing demand for oil and natural gas services and products may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Finally, many scientists have concluded that increasing concentrations of GHG in the atmosphere may have significant physical climate effects, such as increased frequency and severity of storms, droughts, wildfires, floods and other climate events that could have an adverse effect on our and our customers’ operations.

Imposition of laws, executive actions or regulatory initiatives to restrict, delay or cancel leasing, permitting or drilling activities in deepwaters of the United States or foreign countries may reduce demand for our services and products and have a material adverse effect on our business, financial condition or results of operations.

We provide products and services for oil and natural gas E&P customers operating offshore in the deepwaters of the United States and in other countries. In the United States, President Biden issued an executive order in January 2021 that commits to substantial action on climate change, calling for, among other things, the elimination of subsidies provided to the fossil fuel industry and an increased emphasis on climate-related risks across government agencies and economic sectors. On January 20, 2025, the Trump Administration issued an executive order seeking to revoke the January 2021 executive order. In September 2023, the Biden Administration announced that federal agencies will be directed to consider the social cost of GHGs in agency budgeting, procurement and other agency decisions, including in environmental reviews conducted pursuant to the National Environmental Policy Act, where appropriate. On March 12, 2025, the Trump Administration announced an action to revisit the use of the social cost of GHGs. Additionally, regulatory agencies at the federal, state or local level may issue new or amended laws or rulemakings regarding deepwater leasing,

permitting or drilling, including moratoriums on drilling, which could result in more stringent or costly restrictions, delays or cancellations in offshore oil and natural gas E&P activities. Additionally, decisions regarding federal offshore leasing have been subject to legal challenges that could delay or suspend offshore lease auctions, adversely affecting our customers’ businesses and reducing demand for our services. In September 2023, the Biden Administration announced a new five-year offshore leasing plan for the U.S. Gulf of Mexico, which the Trump Administration sought to reverse via executive order in January 2025. The Biden Administration’s plan, if and to the extent retained under the Trump Administration, calls for a maximum of three offshore lease sales, in 2025, 2027 and 2029, and no lease sales were held in 2024. The five-year lease plan would represent the smallest number of planned sales in the history of the offshore leasing program. On January 6, 2025, President Biden issued a Memorandum of Withdrawal pursuant to the Outer Continental Shelf Lands Act of the entire U.S. East Coast, the eastern Gulf of Mexico, the Pacific off the coasts of Washington, Oregon and California, and additional portions of the Northern Bering Sea in Alaska from oil and gas leasing, which the Trump Administration sought to reverse by executive order in January 2025. On January 26, 2024, the Biden Administration implemented a temporary pause on the U.S. Department of Energy’s (“DOE”) review of pending decisions for authorization to export liquified natural gas (“LNG”) to non-Free Trade Agreement countries while the DOE reviews and updates the underlying analyses for such decisions using more current data to account for considerations like the environmental and climate change impacts of LNG. The temporary pause was then overturned by the U.S. District Court for the Western District of Louisiana in July 2024, and the Trump Administration restarted the review of new LNG export terminals via executive order in January 2025. On April 12, 2024, the U.S. Department of the Interior (“DOI”) published a final rule to revise the Bureau of Land Management’s oil and gas leasing regulations, which revises fiscal terms of the onshore federal oil and gas leasing program, including for bonding requirements, royalty rates and minimum bids. It is not possible to predict the impact of the Trump Administration on these climate and energy initiatives at this time. While the Trump Administration may seek to reverse some or all of these initiatives, it is unknown whether such reversals will ultimately be successful.

Any new legislation, executive actions or regulatory initiatives, whether in the United States or in other countries, that impose increased costs or more stringent operational standards or result in significant delays, cancellations or disruptions in our customers’ operations could increase the risk of losing leasing or permitting opportunities, result in expired leases due to the time required to develop new technology or increased supplemental bonding costs or cause our customers to incur penalties, fines or shut-in production at one or more of their facilities, any or all of which could reduce demand for our services. We cannot predict with any certainty the full impact of any new laws, regulations, executive actions or regulatory initiatives on our customers’ drilling operations or the opportunity to pursue such operations, or on the cost or availability of insurance to cover the risks associated with such operations. The matters described above, individually or in the aggregate, could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We face various risks associated with increased activism against oil and natural gas exploration and development activities.

Opposition toward oil and natural gas drilling and development activity, and to companies associated therewith, has been growing globally. Companies in or associated with the oil and natural gas industry are often the target of activist efforts from both individuals and non-governmental organizations regarding safety, human rights, environmental matters, sustainability and business practices. Anti-development activists are working to, among other things, delay or cancel certain operations such as offshore drilling and development.

Future activist efforts could result in the following:

•

decreased oil and gas drilling and exploration, in particular in the offshore industry;

•

increased focus of investors, customers and other stakeholders on sustainability and the energy transition;

•

decreased ability for us and our customers to access the capital markets, including the ability to raise equity capital and debt financing;

•

reputational harm, if we do not adequately identify or manage ESG-related risks or if there are negative perceptions of our response to ESG issues;

•

restrictions on the use of certain operating practices;

•

legal challenges or lawsuits against us or our customers;

•

damaging publicity about us;

•

increased regulation;

•

increased costs of doing business as a result of our efforts to address ESG issues important to our stakeholders, including providing expanded reporting on ESG issues;

•

declines in our stock price;

•

limitations on our ability to refinance our debt; and

•

reduction in demand for our products and services.

There are various corporate and non-governmental initiatives that are focused on voluntary reductions of GHG emissions. These developments, and public perception relating to climate change, may shift demand from oil and natural gas towards an investment in relatively lower carbon emitting energy sources and alternative energy solutions. If, for example, new energy sources become more competitive than oil and natural gas globally, it could have a material effect on our results of operations.

Additionally, certain segments of the investor community have recently expressed negative sentiment towards investing in the oil and gas industry and associated businesses. Climate change-related developments in particular may result in negative perceptions of the traditional oil and gas industry and in turn reputational risks involving business activities associated with petroleum product exploration and production. There have been efforts in recent years, for example, to influence the investment community, including investment advisors, institutional lenders, insurance companies and certain sovereign wealth, pension and endowment funds and other groups, by promoting divestment of fossil fuel equities and pressuring lenders to limit funding and insurance underwriters to limit coverages to companies engaged in the extraction of fossil fuel reserves. Some financial institutions have begun shifting some or all of their investment into non-fossil fuel related sectors, and additional financial institutions may elect to do so in the future. Some investors, including certain pension funds, university endowments and family foundations, have stated policies to reduce or eliminate their investments in the oil and natural gas sector based on social and environmental considerations. Institutional lenders who provide financing to companies associated with the oil and gas industry have also become more attentive to sustainable lending practices, and some may elect not to provide traditional energy producers or companies that support such producers with funding. There is also a risk that financial institutions will be required to adopt policies that have the effect of reducing the funding provided to the fossil fuel sector. Enhanced climate disclosure requirements could accelerate the trend of certain stakeholders and lenders restricting or seeking more stringent conditions with respect to their investments in certain carbon intensive sectors. Such developments could ultimately result in reduced demand for our products and services or reduce our access to, and increase the cost of, debt or capital.

Any legislation, regulatory programs, technological advances or social pressures related to climate change could increase our or our customers’ operating and compliance costs, reduce demand for our products and services and, together with negative investor sentiment, have a material adverse effect on our business, financial condition, results of operations and cash flows.

Negative public perception can lead to additional regulatory burdens and reduced business opportunities for us.

Increasing attention to climate change and natural capital, societal expectations on companies to address climate change, investor and societal expectations regarding regulatory and voluntary ESG initiatives and disclosures and consumer demand for alternative sources of energy may result in increased costs (including but not limited to increased costs associated with compliance, stakeholder engagement, contracting and insurance), reduced demand for our customers’ hydrocarbon products and our product and services, reduced profits, increased legislative and judicial scrutiny, investigations and litigation and negative impacts on our stock price and access to capital markets. Negative public perception regarding our industry and the oil and gas industry may lead to increased regulatory scrutiny, which may, in turn, lead to new state and federal safety, environmental, climate change and ESG laws, regulations, guidelines or enforcement interpretations. Additionally, environmental and other advocacy groups may oppose our or our customers’ operations through organized protests, attempt to block or sabotage our customers’ operations, intervene in regulatory or administrative proceedings involving our customers’ assets or file lawsuits or other actions designed to prevent, disrupt or delay the development or operation of our and our customers’ assets. These actions may increase our costs and reduce our customers’ production levels over time, which, as a result, may reduce demand for our products and services. Moreover, governmental authorities exercise considerable discretion in the timing and scope of permit issuance and the public may engage in the permitting process, including through intervention in the courts. Negative public perception could cause the permits that we or our customers require to conduct operations to be withheld, delayed or burdened by requirements that restrict our or our customers’ ability to profitably conduct business. Ultimately, this could make it more difficult to secure funding for our operations.

In addition, failure or a perception (whether or not valid) of failure to implement ESG strategies or achieve ESG goals or commitments, including any GHG reduction goals or commitments, could result in governmental investigations or enforcement, private litigation and damage our reputation, cause our investors or consumers to lose confidence in the Company and negatively impact our operations. While we may create and publish disclosures regarding ESG matters, it is possible that the statements in those disclosures may be considered or found to be based on hypothetical expectations and assumptions that may or may not be representative of current or actual risks or events or forecasts of expected risks or events, including the costs associated therewith. Such expectations and assumptions are necessarily uncertain and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established single approach to identifying and measuring many ESG matters. Such disclosures may also be partially reliant on third-party information that we have not or cannot independently verify. Additionally, we expect there will likely be increasing levels of regulation, disclosure-related and otherwise, with respect to ESG matters, and increased regulation will likely lead to increased compliance costs as well as scrutiny that could heighten all of the risks identified in this risk factor.

In addition, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating companies on their approach to ESG matters. Such ratings are used by some investors to inform their investment and voting decisions. Unfavorable ESG ratings and recent activism directed at shifting funding away from companies with fossil fuel-related assets could lead to increased negative investor sentiment toward us, our customers and our respective industries and to the diversion of investment to other industries, which could have a negative impact on the price of our Class A common stock and our or our customers’ access to and cost of capital. Also, institutional lenders may decide not to provide funding for fossil fuel energy companies or their suppliers based on climate change-related concerns, which could affect our or our customers’ access to capital for potential growth projects. Moreover, to the extent ESG matters negatively impact our or the fossil fuel industry’s reputation, we may not be able to compete as effectively to recruit or retain employees, which may adversely affect our operations.

The EU taxonomy system that classifies environmentally sustainable activity could have a material impact on how we conduct business.

The EU taxonomy system is a classification system that sets out a list of environmentally sustainable economic activities. It forms part of the EU’s plan to scale up sustainable investment and implement the European Green Deal. The EU Taxonomy Regulation (Regulation 2020/852) (the “EU Taxonomy”) entered into force on July 12, 2020. Since then, the EU has implemented Delegated Acts to further expand on the EU Taxonomy framework. The Climate Delegated Act, the Complementary Climate Delegated Act and the Environmental Delegated Act (each, as amended) set out a list of eligible activities along with technical screening criteria for when the activities can be considered sustainable. We continue to monitor and invest in EU Taxonomy-aligned activities.

The EU Taxonomy could have an impact on us as it sets out criteria for what is considered an environmentally sustainable economic activity, and we may either look to adjust our strategy to undertake more activities that are eligible and aligned with the EU Taxonomy or, to the extent we do not, we may be viewed more negatively by certain stakeholders in this regard. We plan to take steps to reduce our environmental impact in order to qualify. This may include reducing GHG emissions, investing in renewable energy sources and looking into other business segments.

We will be required to publicly report the EU Taxonomy-alignment of our activities in coming years as we begin undertaking CSRD reporting. As a result, to the extent that our public disclosures of EU Taxonomy-alignment do not demonstrate that we are improving, or are likely to meet any goals or targets that we have set in this regard, that may negatively impact stakeholder sentiment in relation to our environmental claims and reputation. We have assessed our economic activity and have concluded that none of our economic activities are considered eligible for 2023.

On February 26, 2025, the European Commission published a proposal involving, among other things, significant simplifications of the CSRD and the EU Taxonomy. For the CSRD, the European Commission’s proposal includes, among other things, a postponed application for certain companies, a reduced scope of companies covered, as well as revised reporting standards (ESRS). As for the EU Taxonomy, the European Commission’s proposal includes, among other things, a reduction of the scope of companies covered and simplifications of the reporting templates. On April 17, 2025, the proposed postponements relating to the obligations of the CSRD entered into force through Directive (EU) 2025/794, which requires EU member states to adopt the changes into domestic legislation by December 31, 2025 at the latest. For the other proposed simplifications of the CSRD and the EU Taxonomy to enter into force, approval by the European Parliament and the Council of the European Union is needed. As of May 2, 2025, it is uncertain whether or not these simplifications will be approved.

We are committed to continually reducing our impact on the environment. We design products and services that reduce undesirable environmental effects and provide for the safe and efficient utilization of energy and natural resources. Our operations are carried out with efficient use of materials and energy and with a focus on minimizing waste and damage to the environment. We strive to ensure that products can be recycled or safely disposed.

Risks related to legal, accounting and tax matters

We have identified material weaknesses in our internal control over financial reporting and may otherwise fail to maintain effective internal control over financial reporting, which could result in a restatement of our financial statements or cause us to fail to meet our reporting obligations.

As a public company, we will be subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) and, if approved for listing, the rules and regulations and the listing standards of Nasdaq.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. We are continuing to develop and refine our disclosure controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we will file with the SEC is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that information required to be disclosed in reports under the Exchange Act is accumulated and communicated to our principal executive and financial officers. We are also continuing to improve our internal control over financial reporting. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we have expended, and anticipate that we will continue to expend, significant resources, including accounting-related costs and significant management oversight.

In the fourth quarter of 2023, we commenced the implementation of an internal controls system that is intended to comply with the rules and requirements of the Sarbanes-Oxley Act. In connection with the preparation of HMH B.V.’s financial statements for the years ended December 31, 2022 and 2023, due in part to inadequate time to fully monitor and test such internal controls system implemented in the fourth quarter of 2023, we identified certain deficiencies in the design and operation of internal control over financial reporting that constituted material weaknesses. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected and corrected on a timely basis. The material weaknesses specifically resulted from the (i) insufficient number of qualified personnel with appropriate GAAP and SEC financial reporting and internal controls expertise; (ii) insufficient risk assessment relating to the financial reporting process; (iii) insufficient design, implementation and operating effectiveness of IT general controls and business process controls; and (iv) insufficient segregation of duties.

Because of the significant remediation efforts we undertook in 2024, we were able to remediate all the deficiencies noted above. These efforts included: (i) hiring five additional qualified personnel with appropriate knowledge of GAAP and SEC financial reporting requirements, IT general controls and business process internal controls; (ii) additional in-house training of personnel involved in the performance of internal controls and, if and to the extent that we deemed necessary, third-party training of personnel; (iii) utilizing third-party consultants to further enhance control procedures and supplement internal resources; (iv) establishing effective monitoring and oversight of controls in line with the internal controls system that we commenced implementing in the fourth quarter of 2023; and (v) enhancing our risk assessment procedures as well as design and implementation of general IT controls and process level controls through process walkthroughs and enhanced monitoring procedures.

As part of the increased internal control monitoring and oversight noted above, we identified a new material weakness related to our operational finance activities leading to ineffective operating effectiveness of process level controls, including controls over revenue cutoff, in subsidiaries in certain regions. This material weakness was a result of insufficient capacity within the operational finance organization within those subsidiaries. We anticipate remediating this deficiency through the addition of qualified personnel with relevant revenue accounting and controls experience to oversee these functions within such regions. If not remediated, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our Class A common stock could be adversely affected and we could become subject to litigation or investigations, which could require additional financial and management resources.

We may discover additional deficiencies or weaknesses in our disclosure controls and procedures and internal control over financial reporting in the future. We cannot assure you that we have identified all, or that we will not in the future have additional, deficiencies. Deficiencies or weaknesses may still exist when we report on the effectiveness of our internal control over financial reporting as required by reporting requirements under Section 404 of the Sarbanes-Oxley Act after the completion of this offering. Any failure to develop or maintain effective controls or any difficulties encountered in their implementation or improvement could harm our operating results or cause us to fail to meet our reporting obligations and may result in a restatement of our

financial statements for prior periods. Any failure to implement and maintain effective internal control over financial reporting could also adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over financial reporting that we will eventually be required to include in our periodic reports that will be filed with the SEC. Once such reporting becomes required, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our internal control over financial reporting is documented, designed or operating. For as long as we are an “emerging growth company” under the JOBS Act, our independent registered public accounting firm will not be required to attest to the effectiveness of our system of internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act. We could be an emerging growth company for up to five years. Please read “Summary—Emerging growth company status.” We must comply with Section 404 of the Sarbanes-Oxley Act (except for the requirement for an auditor’s attestation report) beginning with our fiscal year ending December 31, 2026. We are not currently required to comply with the SEC rules that implement Section 404 of the Sarbanes-Oxley Act and are therefore not required to make a formal assessment of the effectiveness of our internal control over financial reporting for that purpose. As a public company, we will be required to provide an annual management report on the effectiveness of our internal control over financial reporting commencing with our second annual report. Ineffective disclosure controls and procedures and internal control over financial reporting could cause delays in our ability to comply with public company reporting requirements (including under the Exchange Act or stock exchange rules) and could also cause investors to lose confidence in our reported financial and other information, which could have a negative effect on the trading price of our Class A common stock. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on Nasdaq.

Subjective estimates and judgments used by management in the preparation of our financial statements, including estimates and judgments that may be required by new or changed accounting standards, may impact our financial condition and results of operations.

The preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses. Due to the inherent uncertainty in making estimates, results reported in future periods may be affected by changes in estimates reflected in our financial statements for earlier periods. Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. From time to time, there may be changes in the financial accounting and reporting standards that govern the preparation of our financial statements. These changes can materially impact how we record and report our financial condition and results of operations. In some instances, we could be required to apply a new or revised standard retrospectively. If the estimates and judgments we use in preparing our financial statements are subsequently found to be incorrect or if we are required to restate prior financial statements, our financial condition or results of operations could be significantly affected.

Changes in tax laws, regulations and treaties could adversely affect our business, financial condition and results of operations.

Changes in tax laws, regulations and treaties in any of the multiple jurisdictions in which we operate could result in an unfavorable change in our effective tax rate, which could adversely affect our business, financial condition and operating results. Such changes may include (but are not limited to) the taxation of operating income, investment income, dividends received or (in the specific context of withholding tax) dividends paid or the taxation of partnerships and other pass-through entities. As a result, the tax laws in the United States and in jurisdictions in which we do business could change on a prospective or retroactive basis, and any such changes could have an adverse effect on our worldwide tax liabilities, business, financial condition and results of operations. We are unable

to predict what tax reform may be proposed or enacted in the future or what effect such changes would have on our business, but such changes, to the extent they are brought into tax legislation, regulations, policies or practices, could affect our financial position and overall or applicable tax rates in the future in countries where we have operations, reduce post-tax returns to our stockholders and increase the complexity, burden and cost of tax compliance.

For example, on October 8, 2021, the Organization for Economic Co-operation and Development (the “OECD”)/G20 Inclusive Framework on Base Erosion and Profit Shifting released a statement indicating that its members had agreed to a two-pillar solution to address the tax challenges arising from the digitalization of the economy (“Pillar Two”). Pillar Two aims to establish a minimum global tax rate of 15%, assessed through a top-up tax imposed on a country-by-country basis. On December 20, 2021, the OECD released the Pillar Two model rules providing a framework for implementing a 15% minimum tax, also referred to as the Global Anti-Base Erosion (“GloBE”) rules, on earnings of multinational companies with consolidated annual revenue exceeding €750 million. On December 14, 2022, EU Member States agreed to adopt the 15% minimum tax under the Pillar Two model rules, to be enacted into the Member States’ domestic tax law by December 31, 2023, with an effective date of January 1, 2024. For entities with a deviating fiscal year (e.g., July 1-June 30), the rules applied from the start of their first fiscal year beginning after December 31, 2023. As of the date hereof, most EU Member States have implemented the 15% minimum tax. Our global footprint includes operations within the EU, as well as other non-EU jurisdictions that have enacted GloBE related legislation. At this time, we are evaluating what effect, if any, Pillar Two or GloBE will have on our consolidated financial statements. We will continue to closely monitor Pillar Two developments and evaluate the potential impact to us as more foreign countries enact legislation and as new information and guidance becomes available.

In addition, in the United States, the IRA 2022 introduced, among other changes, a 15% corporate minimum tax on certain U.S. corporations and a 1% excise tax on certain stock redemptions by publicly traded U.S. corporations. We do not currently expect that the 15% corporate minimum tax would have an effect on our overall effective tax rate. However, we are currently unable to predict the ultimate impact of the IRA 2022, actions of the Trump Administration or the U.S. Congress or any further changes in U.S. tax law on our business, financial condition and results of operations.

A loss of a major tax dispute or a successful tax challenge to our operating structure, intercompany pricing policies or the taxable presence of our subsidiaries in certain countries could result in a higher taxes on our worldwide earnings, which could result in a significant negative impact on our earnings and cash flows from operations.

Our tax returns are subject to review and examination. We do not recognize the benefit of income tax positions we believe are more likely than not to be disallowed upon challenge by a tax authority. We have in the past been, and currently are, subject to tax audits in the ordinary course of business. If we lose a material tax dispute in any country, our taxes on our worldwide earnings could increase substantially and our earnings and cash flows from operations could be materially adversely affected.

We are subject to various anti-corruption laws and regulations and laws and regulations relating to economic sanctions. Violations of these laws and regulations could have a material adverse effect on our business, financial condition and results of operations.

We are subject to various anti-corruption laws and regulations, including the U.S. Foreign Corrupt Practices Act of 1977, the U.K. Bribery Act 2010, the U.N. Convention Against Corruption, the Norwegian Penal Code (Sections 387, 388 and 389) and the Brazil Clean Company Act. These laws and regulations generally prohibit companies and their intermediaries from engaging in bribery, in receiving or making other improper payments of cash (or anything else of value) to government officials and other persons in order to obtain or retain business or to obtain an improper business benefit. Our business operations also must be conducted in compliance with

applicable economic sanctions laws and regulations, including rules administered by the U.S. Department of the Treasury’s Office of Foreign Assets Control, the U.S. Department of State, the U.S. Department of Commerce, the U.N. Security Council, the EU and its Member States, the United Kingdom, Norway and other relevant authorities.

We strive to conduct our business activities in compliance with relevant anti-corruption laws and regulations, and we have adopted proactive procedures to promote such compliance. While we are not aware of issues of historical noncompliance, full compliance cannot be guaranteed. Violations of anti-corruption laws and regulations, or even allegations of such violations, could result in civil or criminal penalties or other fines or sanctions, including prohibition of our participating in or curtailment of business operations in those jurisdictions and the seizure of assets, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. Moreover, we may be held liable for actions taken by local partners or agents in violation of applicable anti-bribery laws and regulations, even though these partners or agents may themselves not be subject to such laws and regulations. Further, changes to the applicable laws and regulations, or significant business growth, may result in the need for increased compliance-related resources and costs.

Impairment in the carrying value of long-lived assets could reduce our earnings.

We have a significant number of long-lived assets on our consolidated balance sheet. Under GAAP, we are required to review our long-lived assets for impairment when events or circumstances indicate that the carrying value of such assets may not be recoverable or such assets will no longer be utilized by us. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If business conditions or other factors cause the expected undiscounted cash flows to decline, we may be required to record non-cash impairment charges. Events and conditions that could result in impairment in the value of our long-lived assets include changes in the industry in which we operate, long-term extended reduction in demand for oil and natural gas (and by extension, demand for our products and services), competition, advances in technology, adverse changes in the regulatory environment or other factors leading to a reduction in our expected long-term profitability.

A prolonged downturn in the economic environment could cause an impairment of goodwill or other intangible assets and reduce our earnings.

As of March 31, 2025, we had $303.2 million of goodwill and $130.3 million of other identifiable intangible assets, including customer relationships. Goodwill is recorded when the purchase price of a business exceeds the fair market value of the tangible and separately measurable intangible net assets. GAAP requires us to test goodwill for impairment on an annual basis or when events or circumstances occur indicating that goodwill might be impaired. Any event that causes a reduction in demand for our services could result in a reduction of our estimates of future cash flows and growth rates in our business. These events could cause us to record impairments of goodwill or other intangible assets.

Oilfield anti-indemnity provisions enacted by many U.S. states may restrict or prohibit a party’s indemnification of us.

We typically enter into agreements with our customers governing the provision of our services, which usually include certain indemnification provisions for losses resulting from operations. Such agreements may require each party to indemnify the other against certain claims regardless of the negligence or other fault of the indemnified party; however, many states place limitations on contractual indemnity agreements, particularly

agreements that indemnify a party against the consequences of its own negligence. Furthermore, certain states, including Louisiana, New Mexico, Texas and Wyoming, have enacted statutes generally referred to as “oilfield anti-indemnity acts” expressly prohibiting certain indemnity agreements contained in or related to oilfield services agreements. Such oilfield anti-indemnity acts may restrict or void a party’s indemnification of us, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Risks related to technology and intellectual property

New technology may cause us to become less competitive.

The oilfield equipment and services industry continues to see innovation, such as new drilling equipment, techniques and services using new technologies, some of which may be protected by patents or other intellectual property protections. Although we believe our technologies, products and services currently give us a competitive advantage, as competitors and others use or develop new or comparable technologies in the future, we may lose market share or be placed at a competitive disadvantage. Further, we may face competitive pressure to develop, implement or acquire certain new technologies at a substantial cost. Some of our competitors have greater financial, technical and human resources that may give them a competitive advantage in developing, implementing and acquiring new technologies. Alternative products and services using new technologies may compete with or displace our products and services. We may not be able to successfully differentiate our products and services from those of our competitors, or the relative value of our products and services may be eroded. We cannot be certain that we will be able to continue to develop, implement and acquire new technologies, products or services. For example, we may encounter resource constraints, technical barriers or other difficulties that would delay introduction of new products and services in the future. Additionally, the time and expense invested in product development may not result in commercial applications. Limits on our ability to develop, bring to market, implement and effectively use new technologies may have a material adverse effect on our business, financial condition, results of operations and cash flows, including a reduction in the value of assets replaced by new technologies.

Our intellectual property rights may be inadequate to protect our business.

We attempt to protect our intellectual property rights in the United States and in foreign countries through a combination of patent, trademark, copyright and trade secret laws, as well as license agreements and third-party non-disclosure and assignment agreements. Our failure to adequately protect our intellectual property could have a material adverse effect on our business, financial condition and results of operations.

While we believe that we are not dependent on any one patent to protect our material technology, obtaining patent protection for our products is an important component of our overall competitive business strategy. Patents typically give the owner the right to exclude third parties from making, using, selling and offering for sale the inventions claimed in the patents in the applicable country. Patent rights do not necessarily grant the owner of a patent the right to practice the invention claimed in a patent, but merely the right to exclude others from practicing the invention claimed in the patent. Patent laws and their implementation vary throughout the world. Some foreign countries do not protect intellectual property rights to the same extent as the United States. Further, policing the unauthorized use of our intellectual property in foreign jurisdictions may be difficult and expensive. Therefore, our intellectual property rights may not be as strong or as easily enforced outside of the United States. It may also be possible for a third party to design around our patents. Patent rights have territorial limits. While we generally apply for patents in countries where we intend to make, have made, use or sell patented products or services, we may not accurately predict all of the countries where patent protection will ultimately be desirable, and we do not have patents in every jurisdiction in which we conduct

business. Also, drilling may be conducted in international waters and therefore may not fall within the scope of any country’s patent jurisdiction. As a result, we may not be able to enforce our patents against infringement occurring in international waters. The patents we own could be challenged, invalidated or circumvented by others. In any event, our patent portfolio will not protect all aspects of our business and for the aspects it does protect, the portfolio may not provide us with meaningful protection or provide us with a commercial advantage, which would not prevent third parties from entering the same market. While we have patented some of our key technologies, we do not patent all of our proprietary technology, even when regarded as patentable. The process of seeking patent protection can be long and expensive. Further, there can be no assurance that patents will be issued from currently pending or future applications or that, if patents are issued, they will be of sufficient scope or strength to provide meaningful protection or any commercial advantage to us.

Trademarks are also of considerable importance to the marketing of our products. Although we typically register trademarks in many of the countries where the trademarked products are used or generate revenue, we have not registered our trademarks in every country where we do or intend to do business. Moreover, we cannot guarantee that our attempts to register trademarks in the future will be successful, and third parties could seek to oppose the registration of our trademarks, cancel any registrations or otherwise challenge our rights in trademarks. We also benefit from common law protection for our trademarks in those countries where such common law rights are recognized. If we lose the rights to use our trademarks or our rights are challenged, we could be forced to rebrand the corresponding products and devote resources to marketing new brands. In turn, this could result in a loss of goodwill or substantial expenditure or otherwise have a material adverse effect on our business.

We also rely on trade secret laws and contracts to protect our confidential and proprietary information. We attempt to limit access to and distribution of our technology and trade secrets by customarily entering into confidentiality agreements with our employees, consultants, partners, customers, potential customers and suppliers. There can be no assurance, however, that these agreements will provide meaningful protection for our trade secrets, in the event of any unauthorized use, misappropriation or disclosure of them. Despite our efforts to protect our proprietary rights, former employees, consultants, partners, customers, suppliers or other third parties may, in an unauthorized manner, attempt to use, copy or otherwise obtain and market or distribute our intellectual property rights or technology or otherwise develop a product with the same functionality as our technology. Moreover, trade secret protection does not prevent third parties from independently obtaining or developing similar information. Publicly available information (for example, information in expired patents, published patent applications and scientific literature) can also be used by third parties to independently develop technology. We cannot provide assurance that this independently developed technology will not be equivalent or superior to our proprietary technology. Inability to maintain the proprietary nature of our technologies could have a material adverse effect on our business.

We rely on copyright laws to protect our software and offerings, such as, among others, DEAL, SeaLytics, SeaPrime and SeaONYX, and we register the copyrights in the vast majority, but not all, of our copyrightable works. Copyrights must be registered in the United States before the copyright owner may bring an infringement suit in the United States. Furthermore, if a U.S. copyright is not registered before infringement starts or within three months of publication of the underlying work, the copyright owner is precluded from seeking statutory damages or attorneys’ fees in a U.S. enforcement action, and is limited to seeking actual damages and lost profits. Accordingly, if one of our unregistered U.S. copyrights is infringed by a third party, we will need to register the copyright before we can file an infringement suit in the United States, and our remedies in any such infringement suit may be limited.

Our inability to obtain and retain licenses to intellectual property owned by third parties for the commercialization of our products may negatively impact our prospects and financial results.

In order to commercialize certain of our products, we license third-party patents, unpatented technology and trademarks in exchange for the performance of other obligations. For example, we are a party to license agreements with a subsidiary of Baker Hughes giving us a limited right to use the terms Vetco^™ and VetcoGray^™ as trademarks on certain products traditionally sold under those trademarks and certain other intellectual property rights relating to the business line Baker Hughes contributed to HMH B.V. at the time of HMH B.V.’s formation. In addition, we are party to another license agreement with Tenaris S.A., via our predecessor in interest, General Electric Company, relating to our wholly owned subsidiary’s use of the Hydril^™ trademark. Our breach of any of these licenses may result in their termination or expose us to financial liability or legal claims and could require us to cease using the trademarks or making, using or selling products that exploit the licensed technology. Our loss of third-party intellectual property rights or inability to license such rights in the future may result in a loss of competitive advantage, decreased revenue or increased operating expenses or otherwise adversely affect our business, financial condition, results of operations, cash flow and prospects.

We may have to enforce our intellectual property against others, and defend against intellectual property challenges against us, which could materially and adversely affect our business and competitive position.

The protection of our intellectual property rights is essential to maintaining our competitive position and recognizing the value of our investments in technology and intellectual property in our existing and future

products. Intellectual property litigation and threats of litigation are becoming more common in the oilfield equipment and services industry. We may in the future be involved in litigation, in the United States or abroad, to enforce our patents or other intellectual property rights, protect our trade secrets and know-how or defend ourselves against allegations of intellectual property infringement brought by our competitors or other third parties.

Policing unauthorized use of our intellectual property rights is difficult, and nearly impossible on a worldwide basis. Therefore, we cannot be certain that the steps we have taken or will take in the future will prevent misappropriation of our technology or intellectual property rights. In the event that we need to enforce our intellectual property against an infringer or party otherwise misappropriating or violating our intellectual property rights, litigation can require multiple years to come to resolution or settlement, and even if we ultimately prevail, we may be unable to realize adequate protection of our competitive position. In addition, these actions commonly result in defendants attacking the validity of the asserted intellectual property. Even with a meritorious case, there is no guarantee of success, and intellectual property litigation can result in substantial costs and diversion of management resources. In the event that one or more of our patents are challenged, a court, the United States Patent and Trademark Office (“USPTO”) or its equivalent in foreign jurisdictions may invalidate a patent or determine that a patent is not enforceable, which could harm our competitive position. If any of our patents are invalidated, or if the scope of the claims in any of these patents is limited by a court decision, USPTO decision or decision from an equivalent authority in a foreign jurisdiction, we could be prevented from pursuing certain litigation matters or licensing the invalidated or limited portion of such patents. Such adverse decisions could negatively impact our business, financial condition, results of operations and cash flows.

We also face the risk of claims that we have infringed third parties’ patents or other intellectual property rights. Our competitors in both the United States and foreign countries, many of which have substantially greater resources and have made substantial investments in competing technologies, may have applied for or obtained, or may in the future apply for and obtain, patents that will prevent, limit or otherwise interfere with our ability to make and sell our products. The large number of patents, the rapid rate of new patent issuances, the complexities

of the technology involved and the uncertainty of litigation increase the risk of potential litigation. In the event that we or one of our customers becomes involved in a dispute over infringement, misappropriation or other violation of intellectual property rights relating to equipment or technology owned or used by us, services performed by us or products provided by us, we may lose access to important equipment or technology or our ability to provide our products or services. In addition, we could be required to cease use of some equipment or technology or forced to modify our equipment, technology, products or services, and we could be required to pay substantial damages. We could also be required to pay license fees or royalties for the use of equipment, technology or products. We may not be able to obtain the necessary licenses on acceptable terms, or at all, or be able to re-engineer our products successfully. If our inability to obtain required licenses for our technologies or products prevents us from selling our products, that could adversely impact our financial condition and results of operations. Further, we may lose a competitive advantage in the event we are unsuccessful in enforcing our rights against third parties. All of the foregoing could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We may be subject to claims that our employees, consultants or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers or claims asserting ownership of what we regard as our own intellectual property.

Some of our employees and consultants are currently or were previously employed at other companies in our field, including our competitors or potential competitors. Although we try to ensure that our employees and consultants do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these individuals have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individual’s current or former employer. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

Although, as a condition of employment or engagement, our employees and contractors acknowledge that all intellectual property developed in the scope of their employment or in performance of services belongs to us as a work for hire, those personnel involved in developing intellectual property we regard as our own may dispute whether such intellectual property is owned by us. In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of inventions to execute agreements assigning such inventions to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops inventions that we regard as our own. An employee or other party may refuse to execute an assignment of intellectual property rights, or the assignment agreements may be breached, and we may be forced to bring claims or defend claims that such parties may bring against us to determine the ownership of what we regard as our intellectual property. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Errors or failures of our proprietary software may result in liability or reputational damages or otherwise adversely affect our business.

Our software products include drilling optimization, automation and other solutions that support the drilling operations of our customers. Our development processes and quality control programs for our software are intended to avoid the introduction of defects and errors in our proprietary software. However, we cannot guarantee that we have identified all defects and errors in our software, or that ongoing maintenance and development of the software will not introduce defects and errors in it. In addition, our software uses open source software, which may contain undetected defects or errors now or in the future. Defects or errors in our software products may result in disruptions to or failures in the drilling operations that they support. Disruption

or failure of our customers’ drilling operations may result in accidents and financial liability for us and our customers, which could have a material adverse effect on our reputation, business, financial condition, results of operations and cash flows.

Cybersecurity attacks, IT system failures and network disruptions may result in potential liability or reputational damage or otherwise adversely affect our business.

Many of our business and operational processes are heavily dependent on traditional and emerging IT systems, some of which are managed by us and some of which are managed by third-party service providers, to conduct day-to-day operations, improve safety and efficiency and lower costs. We use computerized systems to help run our financial and operations functions, including the processing of payment transactions and storing confidential records, which may subject our business to increased risks. If we experience a material failure of any of our financial, operational or other technology systems, interruption of service, compromise of data security or other cybersecurity threat, our financial results could be adversely affected. These risks could occur either as a result of inadvertent error or deliberate tampering with or manipulation of our operational systems. In addition, dependence upon automated systems may further increase the risk of operational system flaws.

Cybersecurity incidents are increasing in frequency and evolving in sophistication and can include, but are not limited to, installation of malicious software, phishing scams, ransomware, attempts to gain unauthorized access to systems or data and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and corruption of data. In addition, cybersecurity risk is exacerbated with the advancement of technologies like artificial intelligence, which malicious third parties are using to create new, sophisticated and more frequent attacks. Unauthorized access to our customer or employee data or other proprietary or commercially sensitive information could lead to data integrity issues, communication interruption or other disruptions in our operations or planned business transactions, any of which could have a material adverse impact on our business and operations.

We have implemented security measures, internal controls and testing that are designed to detect and protect against cyberattacks. We regularly update and review our testing protocols; however, no security measure is infallible. Despite these measures and any additional measures we may implement or adopt in the future, our facilities and systems, and those of our third-party service providers, have been and remain potentially vulnerable to security breaches, computer viruses, lost or misplaced data, programming errors, scams, burglary, human errors, misdirected wire transfers and other adverse events, including threats to our critical operations technologies and process control networks. The increased number of employees relying on remote access to our information systems since the COVID-19 pandemic increases our exposure to potential cybersecurity breaches. Third-party systems on which we rely could also suffer such attacks or operational system failures. Such attacks and incidents may continue to occur in the future. While to date no incidents have had a material impact on our operations or financial results, we cannot guarantee that material incidents will not occur in the future.

Any of these occurrences could result in material harm to our business, including ransom payments, significant remediation and cybersecurity protection costs, loss of customer or employee data, loss of intellectual property or proprietary information, diversion of management or workforce attention, litigation and legal risks, including regulatory actions, potential liability, reputational damage or damage to our competitiveness, stock price and long-term stockholder value, or otherwise have an adverse effect on our business, operations and financial results. In addition, laws and regulations governing cybersecurity, data privacy and the unauthorized disclosure of confidential or protected information, including the EU’s General Data Protection Regulation, the United Kingdom’s General Data Protection Regulation, the Swiss Federal Act on Data Protection and recent legislation in certain U.S. states pose increasingly complex compliance challenges and may potentially elevate costs, and failure to comply with these laws and regulations could result in significant penalties and legal liability.

Use of artificial intelligence (“AI”) tools and network disruptions may result in potential liability, exposure of personal or proprietary information or otherwise adversely affect our business.

The use of third-party and open-source AI tools, such as ChatGPT, by our employees and consultants could pose risks relating to the protection of data, including the potential exposure of our proprietary, confidential or otherwise protected information to unauthorized recipients and the misuse of our or third-party intellectual property. Use of AI tools may result in allegations or claims against us related to violation of third-party intellectual property rights, unauthorized access to or use of proprietary information and failure to comply with open-source software requirements.

Risks related to our indebtedness

Our indebtedness could materially adversely affect our financial condition.

As of March 31, 2025, on a pro forma basis, after giving effect to the corporate reorganization and this offering and the application of the net proceeds therefrom, our total indebtedness was $ million, including $ million of outstanding borrowings under the Revolver (as defined herein) and $200.0 million aggregate principal amount of the Senior Secured Bonds (as defined herein), and our outstanding borrowing capacity under the Revolver was $ million. Our indebtedness could have important consequences, including the following:

•

making it more difficult for us to satisfy our other obligations;

•

limiting our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions or other general corporate purposes;

•

requiring us to dedicate a substantial portion of our cash flows to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, acquisitions and other general corporate purposes;

•

increasing our vulnerability to general adverse economic and industry conditions;

•

limiting our flexibility in planning for and reacting to changes in the industry in which we compete;

•

placing us at a disadvantage compared to other, less leveraged competitors; and

•

increasing our cost of borrowing.

We may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to satisfy our obligations under applicable debt instruments, which may not be successful.

Our ability to make scheduled payments on or to refinance our indebtedness obligations depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and certain financial, business and other factors beyond our control. We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness.

If our cash flows and capital resources are insufficient to fund debt service obligations, we may be forced to reduce or delay investments and capital expenditures, sell assets, seek additional capital or restructure or refinance indebtedness. Our ability to restructure or refinance indebtedness will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of indebtedness could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict business

operations. The terms of existing or future debt instruments may restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and principal on outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness. In the absence of sufficient cash flows and capital resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet debt service and other obligations. Our debt agreements may restrict our ability to dispose of assets and our use of the proceeds from such disposition. We may not be able to consummate those dispositions, and the proceeds of any such disposition may not be adequate to meet any debt service obligations then due.

If we are unable to meet our debt service and repayment obligations, we would be in default under the terms of our debt agreements, which would allow our creditors at that time to declare all outstanding indebtedness to be due and payable. Under these circumstances, our lenders and creditors could compel us to apply all of our available cash to repay our borrowings. In addition, our lenders could seek to foreclose on any of our assets that constitute their collateral. If the amounts outstanding under our indebtedness were to be accelerated, or were the subject of foreclosure actions, our assets may not be sufficient to repay in full the money owed to the lenders, and such payment acceleration would have a material adverse effect on our liquidity, business and financial condition.

Restrictions in our existing and future debt agreements could limit our growth and our ability to engage in certain activities.

Our existing debt agreements contain, and our future debt agreements will likely contain, a number of significant covenants, including restrictive covenants that may limit our ability to, among other things:

•

incur additional indebtedness and guarantee indebtedness;

•

pay dividends or make other distributions on, or redeem or repurchase, capital stock and make other restricted payments;

•

prepay, redeem or repurchase certain debt;

•

issue certain preferred stock or similar equity securities;

•

make loans, investments or capital expenditures;

•

consummate certain asset sales;

•

make certain acquisitions;

•

engage in transactions with affiliates;

•

grant or assume liens;

•

alter the businesses we conduct;

•

enter into agreements restricting our subsidiaries’ ability to pay dividends; and

•

consolidate, merge or transfer all or substantially all of our assets.

Furthermore, our debt agreements contain certain other operating and financial covenants, including the obligation to satisfy a certain debt-to-equity ratio, a leverage ratio, interest cover ratio and a liquidity requirement. Our ability to comply with the covenants and restrictions contained in our debt agreements may be affected by events beyond our control, including prevailing economic, financial and industry conditions. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired.

If we violate any of the restrictions, covenants, ratios or tests in our debt agreements, all or a significant portion of our indebtedness may become immediately due and payable, and our lenders’ commitment to make further loans to us may terminate. We might not have, or be able to obtain, sufficient funds to make these accelerated payments. The Revolver is secured by liens on substantially all of HMH B.V.’s assets, including the equity of its material subsidiaries, and guarantees, either directly or indirectly, from its material subsidiaries. The Senior Secured Bonds are secured by liens on substantially all of HMH B.V.’s assets, including the equity of its material subsidiaries, and guarantees, either directly or indirectly, from its material subsidiaries. Any acceleration of our debt obligations could result in a foreclosure on the collateral securing such debt. Our debt agreements also require us to make mandatory prepayments and repurchases in certain circumstances. Any future required prepayments or repurchases will reduce our cash available for investment in our business. Any subsequent replacement of our debt agreements or any new indebtedness could have similar or greater restrictions. In order to implement the corporate reorganization and the listing of our Class A common stock on Nasdaq, certain technical amendments have been made to the agreement governing the Senior Secured Bonds and the Revolver. Certain costs were associated with entering into the amendment of the Senior Secured Bonds and obtaining consent thereunder, including a one-time consent fee payable to the holders of the Senior Secured Bonds. See “Management’s discussion and analysis of financial condition and results of operations—Liquidity and capital resources—Debt agreements.”

An increase in interest rates would increase the cost of servicing our indebtedness and could reduce our net income and cash flows.

The Revolver provides for, and our future debt agreements may provide for, debt incurred thereunder to bear interest at variable rates. As a result, increases in interest rates could increase the cost of servicing such indebtedness, even though the principal amount borrowed may remain the same, and materially reduce our net income and cash flows, including cash available for servicing our indebtedness.

We and our subsidiaries may be able to incur substantial indebtedness.

We may incur substantial additional indebtedness in the future. Although the terms of the agreements governing the Revolver, the Shareholder Loans and the Senior Secured Bonds contain restrictions on our ability to incur additional indebtedness, these restrictions are subject to a number of important exceptions, and indebtedness incurred in compliance with these restrictions could be substantial. If we and our subsidiaries incur significant additional indebtedness, the related risks to our financial condition could increase.

Risks related to this offering and ownership of our Class A common stock

We are a holding company. Our only material asset after completion of this offering will be our equity interest in HMH B.V., and we will accordingly be dependent upon distributions from HMH B.V. to pay taxes, make payments under the Tax Receivable Agreement and cover our corporate and other overhead expenses.

We are a holding company and will have no material assets other than our equity interest in HMH B.V. Please see “Corporate reorganization.” We will have no independent means of generating revenue. To the extent HMH B.V. has available cash and subject to the terms of any existing and future debt instruments, we intend to cause HMH B.V. to make (i) generally pro rata distributions to its shareholders, including us, in an amount sufficient to allow its shareholders to pay taxes on their allocable share of HMH B.V.’s taxable income from U.S. and non-U.S. operations, as applicable, and to allow us to make payments under the Tax Receivable Agreement we will enter into with the Principal Stockholders in connection with the closing of this offering and (ii) non-pro rata payments to us to reimburse us for our corporate and other overhead expenses. To the extent that we need funds and HMH B.V. or its subsidiaries are restricted from making such distributions or payments under

applicable law or regulation or under the terms of any current or future financing arrangements, or are otherwise unable to provide such funds, our liquidity and financial condition could be materially adversely affected.

Moreover, because we will have no independent means of generating revenue, our ability to make payments under the Tax Receivable Agreement is dependent on the ability of HMH B.V. to make distributions to us in an amount sufficient to cover our obligations under the Tax Receivable Agreement. This ability, in turn, may depend on the ability of HMH B.V.’s subsidiaries to make distributions to it. The ability of HMH B.V., its subsidiaries and other entities in which it directly or indirectly holds an equity interest to make such distributions will be subject to, among other things, (i) the applicable provisions of Dutch law (or other applicable jurisdiction) that may limit the amount of funds available for distribution and (ii) restrictions in relevant debt instruments issued by HMH B.V. or its subsidiaries and other entities in which it directly or indirectly holds an equity interest. To the extent that we are unable to make payments under the Tax Receivable Agreement for any reason, such payments will be deferred and will accrue interest until paid.

No market currently exists for our Class A common stock, and an active, liquid trading market for our Class A common stock may not develop, which may cause shares of our Class A common stock to trade at a discount from the initial offering price and make it difficult to sell the shares of Class A common stock you purchase.

Prior to this offering, there has not been a public trading market for shares of our Class A common stock. We cannot predict the extent to which investor interest in us will lead to the development of a trading market or how active and liquid that market may become. If an active and liquid trading market does not develop or continue, you may have difficulty selling your shares of our Class A common stock at an attractive price or at all. The initial public offering price per share of Class A common stock will be determined by negotiations between us and the underwriters, and may not be indicative of the price at which shares of our Class A common stock will trade in the public market after this offering. The market price of our Class A common stock may decline below the initial offering price and you may not be able to sell your shares of our Class A common stock at or above the price you paid in this offering, or at all. An inactive market may also impair our ability to raise capital by selling our Class A common stock, and it may impair our ability to attract and motivate our employees through equity incentive awards and our ability to acquire other companies, products or technologies by using our Class A common stock as consideration.

We will be required to make payments under the Tax Receivable Agreement for certain tax benefits we may claim, and the amounts of such payments could be significant.

The term of the Tax Receivable Agreement will commence upon the completion of this offering and will continue until all tax benefits that are subject to the Tax Receivable Agreement have been utilized or expired, unless we exercise our right to terminate the Tax Receivable Agreement (or the Tax Receivable Agreement is terminated due to other circumstances, including our breach of a material obligation thereunder or certain mergers or other changes of control), and we make the termination payment specified in the Tax Receivable Agreement. In addition, payments we make under the Tax Receivable Agreement will be increased by any

interest accrued from the due date (without extensions) of the corresponding tax return. In the event that the Tax Receivable Agreement is not terminated, the payments under the Tax Receivable Agreement are anticipated to continue for 16 years after the date of the last redemption of the B.V. Non-Voting Shares.

The payment obligations under the Tax Receivable Agreement are our obligations and not obligations of HMH B.V., and we expect that the payments we will be required to make under the Tax Receivable Agreement will be substantial. Estimating the amount and timing of payments that may become due under the Tax Receivable Agreement is by its nature imprecise. For purposes of the Tax Receivable Agreement, cash savings in tax generally will be calculated by comparing our actual tax liability (determined by using the actual applicable U.S. federal, state, local and foreign income tax rates and franchise tax rates) to the amount we would have been required to pay had we not been able to utilize any of the tax benefits subject to the Tax Receivable Agreement. The amounts payable, as well as the timing of any payments, under the Tax Receivable Agreement are dependent upon significant future events and assumptions, including the timing of the redemptions of B.V. Non-Voting Shares (and, if applicable, acquisitions of Mercury HoldCo Inc. shares), the price of our Class A common stock at the time of each redemption or acquisition, the extent to which such redemptions are taxable transactions, the amount of each Principal Stockholder’s tax basis in its B.V. Non-Voting Shares at the time of the relevant redemption, the depreciation and amortization periods that apply to the increase in tax basis, the utilization of certain NOL carryovers (in the event we acquire Mercury HoldCo Inc. shares), the amount and timing of the utilization of tax attributes, the amount and timing of taxable income we generate in the future, the U.S. federal, state, local and foreign income tax rates and franchise tax rates then applicable and the portion of our payments under the Tax Receivable Agreement that constitute imputed interest or give rise to depreciable or amortizable tax basis. For additional information regarding the Tax Receivable Agreement, see “Certain relationships and related party transactions—Tax Receivable Agreement.”

In certain cases, payments under the Tax Receivable Agreement may be accelerated and significantly exceed the actual benefits, if any, we realize in respect of the tax attributes subject to the Tax Receivable Agreement.

If we experience a change of control (as defined in the Tax Receivable Agreement) or the Tax Receivable Agreement terminates early (at our election or as a result of a material breach of our obligations thereunder), we could be required to make a substantial, immediate lump-sum payment. Any early termination payment may be made significantly in advance of, and may materially exceed, the actual realization, if any, of the future tax benefits to which the termination payment relates, and such early termination payment may exceed our cash on hand and ability to pay.

If we experience a change of control (as defined in the Tax Receivable Agreement) or the Tax Receivable Agreement terminates early (at our election or as a result of a material breach of our obligations thereunder), we could be required to make payments under the Tax Receivable Agreement that exceed our actual cash tax savings under the Tax Receivable Agreement. In these situations, our obligations under the Tax Receivable Agreement could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales or other forms of business combinations or changes of control. There can be no assurance that we will be able to finance our obligations under the Tax Receivable Agreement. Please read “Certain relationships and related party transactions—Tax Receivable Agreement.”

In the event that our payment obligations under the Tax Receivable Agreement are accelerated upon certain mergers, other forms of business combinations or other changes of control, the consideration payable to holders of our Class A common stock could be substantially reduced.

If we experience a change of control (as defined in the Tax Receivable Agreement), we could be obligated to make a substantial, immediate lump-sum payment, and such payment may be significantly in advance of, and

may materially exceed, the actual realization, if any, of the future tax benefits to which the payment relates and such payment may exceed our cash on hand and ability to pay. As a result of this payment obligation, holders of our Class A common stock could receive substantially less consideration in connection with a change of control transaction than they would receive in the absence of such obligation. Accordingly, the Principal Stockholders’ interests may conflict with those of the holders of our Class A common stock. Please read “Risk factors—Risks related to this offering and our Class A common stock—In certain cases, payments under the Tax Receivable Agreement may be accelerated and significantly exceed the actual benefits, if any, we realize in respect of the tax attributes subject to the Tax Receivable Agreement” and ‘‘Certain relationships and related party transactions—Tax Receivable Agreement.”

We will not be reimbursed for any payments made under the Tax Receivable Agreement in the event that any tax benefits are subsequently disallowed.

Payments under the Tax Receivable Agreement will be based on the tax reporting positions that we will determine and the Internal Revenue Service (“IRS”) or another tax authority may challenge all or part of the tax basis increases or other tax benefits covered under the Tax Receivable Agreement, as well as other related tax positions we take, and a court could sustain such challenge. The Principal Stockholders will not reimburse us for any payments previously made under the Tax Receivable Agreement if such basis increases or other tax benefits that have given rise to payments under the Tax Receivable Agreement are subsequently disallowed, except that excess payments made to the Principal Stockholders will be netted against payments that would otherwise be made to the Principal Stockholders, if any, after our determination of such excess. As a result, in such circumstances, we could make payments that are greater than our actual cash tax savings, if any, and may not be able to recoup those payments, which could adversely affect our liquidity.

The Principal Stockholders and their affiliates are not limited in their ability to compete with us, and the corporate opportunity provisions in our amended and restated certificate of incorporation could enable the Principal Stockholders and their affiliates to benefit from corporate opportunities that might otherwise be available to us.

Our governing documents will provide that the Principal Stockholders and their affiliates are not restricted from owning assets or engaging in businesses that compete directly or indirectly with us and that we renounce any interest or expectancy in any business opportunity that may be from time to time presented to the Principal Stockholders or their affiliates. In particular, subject to the limitations of applicable law, our amended and restated certificate of incorporation will, among other things, contain provisions relating to the duties of any affiliate of Baker Hughes or Akastor who is also one of our officers or directors that becomes aware of a potential business opportunity, transaction or other matter (other than one expressly offered to that director or officer solely in his or her capacity as our director or officer).

The Principal Stockholders or their affiliates may become aware, from time to time, of certain business opportunities (such as acquisition opportunities) and may direct such opportunities to other businesses in which they have invested, in which case we may not become aware of or otherwise have the ability to pursue such opportunity. Further, such businesses may choose to compete with us for these opportunities, possibly causing these opportunities to not be available to us or causing them to be more expensive for us to pursue. As a result, our renouncing our interest and expectancy in any business opportunity that may be from time to time presented to the Principal Stockholders and their affiliates could adversely impact our business or prospects if attractive business opportunities are procured by such parties for their own benefit rather than for ours. Please read “Description of capital stock—Corporate opportunities.”

The Principal Stockholders and their affiliates are established participants in the oil and natural gas industry and have resources greater than ours, which may make it more difficult for us to compete with the Principal

Stockholders and their affiliates with respect to commercial activities as well as for potential acquisitions. We cannot assure you that any conflicts that may arise between us and our stockholders, on the one hand, and the Principal Stockholders and their affiliates, on the other hand, will be resolved in our favor. As a result, competition from the Principal Stockholders and their affiliates could adversely impact our results of operations.

In certain circumstances, HMH B.V. will be required to make tax distributions to the Principal Stockholders and us, and the tax distributions that HMH B.V. will be required to make may be substantial.

Pursuant to the partnership agreement of HMH B.V. (the “HMH B.V. Partnership Agreement”), HMH B.V. will, to the extent cash is available and to the extent permitted under applicable law, make generally pro rata cash distributions, or tax distributions, to certain of the Principal Stockholders and us in an amount sufficient to allow its shareholders to pay taxes on their allocable share of HMH B.V.’s taxable income from U.S. and non-U.S. operations, as applicable, and to allow us to make payments under the Tax Receivable Agreement we will enter into with the Principal Stockholders in connection with the closing of this offering. Under applicable tax rules, HMH B.V. is required to allocate net taxable income disproportionately to its shareholders in certain circumstances. The amount of tax distributions will be determined based on an assumed tax rate.

Funds used by HMH B.V. to satisfy its tax distribution obligations will not be available for reinvestment in our business. Moreover, the tax distributions HMH B.V. will be required to make may be substantial. In addition, because these payments will be calculated with reference to an assumed tax rate, and because applicable tax rules require HMH B.V. to allocate net taxable income disproportionately to its shareholders in certain circumstances, these payments may exceed the actual tax liability for some of the shareholders of HMH B.V. If we retain the excess cash received, the Principal Stockholders that hold B.V. Non-Voting Shares would benefit from any value attributable to such accumulated cash balances upon their exercise of the Redemption Right or HMH B.V.’s exercise of the Call Right, as applicable. However, we expect to take steps to eliminate any material cash balances.

The Principal Stockholders will, if and when their voting interests align, initially have the ability to direct the voting of a majority of the voting power of our capital stock, and their interests may conflict with those of our other stockholders.

Holders of shares of our Class A common stock and Class B common stock will vote together as a single class on all matters presented to our stockholders for their vote or approval, except as otherwise required by applicable law or our amended and restated certificate of incorporation. Upon completion of this offering, Baker Hughes will beneficially own % of the total voting power of our capital stock (or % if the underwriters exercise in full their option to purchase additional shares of Class A common stock), and Akastor will beneficially own % of the total voting power of our capital stock (or % if the underwriters exercise in full their option to purchase additional shares of Class A common stock). As a result, the Principal Stockholders will, if and when their voting interests align, initially be able to control matters requiring stockholder approval, including the election and removal of directors, changes to our organizational documents and significant corporate transactions, including any merger, consolidation or sale of all or substantially all of our assets. This concentration of ownership makes it unlikely that any other holder or group of holders of our Class A common stock will be able to affect the way we are managed or the direction of our business. For more information, see “Corporate reorganization,” “Security ownership of certain beneficial owners and management” and “Certain relationships and related party transactions.” The interests of each Principal Stockholder with respect to matters potentially or actually involving or affecting us, such as future acquisitions, financings and other corporate opportunities and attempts to acquire us, may conflict with the interests of our other stockholders.

For example, a Principal Stockholder may have different tax positions from us, especially in light of the Tax Receivable Agreement, that could influence its decisions regarding whether and when to support the disposition

of assets, the incurrence or refinancing of new or existing indebtedness or the termination of the Tax Receivable Agreement and accelerate our obligations thereunder. In addition, the determination of future tax reporting positions, the structuring of future transactions and the handling of any challenge by any taxing authority to our tax reporting positions may take into consideration a Principal Stockholder’s tax or other considerations that may differ from the considerations of us or our other stockholders. Please read “Certain relationships and related party transactions—Tax Receivable Agreement.”

Given this concentrated ownership, at least one of the Principal Stockholders would have to approve any potential acquisition of us. Furthermore, our amended and restated certificate of incorporation and the Stockholder’s Agreement will provide each of the Principal Stockholders with certain powers and protections, including the right to designate to our board of directors (i) two nominees so long as such Principal Stockholder and its affiliates collectively beneficially own at least shares of our common stock and (ii) one nominee so long as such Principal Stockholder and its affiliates collectively beneficially own at least but less than shares of our common stock, and also certain information rights. See the discussion of our amended and restated certificate of incorporation in “Description of capital stock—Anti-takeover provisions” and “Management—Board of directors” and see also “Certain relationships and related party transactions—Stockholders’ Agreement.” In addition, certain of our director nominees are currently employees of the Principal Stockholders or their affiliates. These directors’ duties as employees of the Principal Stockholders or their affiliates may conflict with their duties as our directors, and the resolution of these conflicts may not always be in our or your best interest. Finally, the existence of significant stockholders may have the effect of deterring hostile takeovers, delaying or preventing changes in control or changes in management or limiting the ability of our other stockholders to approve transactions that they may deem to be in the best interests of our company. The Principal Stockholders’ concentration of stock ownership may also adversely affect the trading price of our Class A common stock to the extent investors perceive a disadvantage in owning stock of a company with significant stockholders.

A significant reduction by the Principal Stockholders of their ownership interests in us could adversely affect us.

Upon the expiration of the lock-up restrictions on transfers or sales of or disposition or hedge of any share or any securities convertible into or exchangeable for shares of our capital stock following the completion of this offering, none of the Principal Stockholders will be subject to any contractual obligation to maintain its ownership interest in us and may elect at any time thereafter to sell all or a substantial portion of or otherwise reduce its ownership interest in us. In the event the Principal Stockholders reduce their ownership interest in us, a Principal Stockholder and its affiliates may have less incentive to assist in our success and the individuals initially appointed to our board of directors by a Principal Stockholder may resign. Such actions could adversely affect our ability to successfully implement our business strategies, which could adversely affect our business, financial condition and results of operations.

If HMH B.V. were to become a publicly traded partnership taxable as a corporation for U.S. federal income tax purposes, we and HMH B.V. might be subject to potentially significant tax inefficiencies, and we would not be able to recover payments previously made by us under the Tax Receivable Agreement even if the corresponding tax benefits were subsequently determined to have been unavailable due to such status.

We intend to operate such that HMH B.V. does not become a publicly traded partnership taxable as a corporation for U.S. federal income tax purposes. A “publicly traded partnership” is a partnership the interests of which are traded on an established securities market or are readily tradable on a secondary market or the substantial equivalent thereof. Under certain circumstances, redemptions or acquisitions of B.V. Non-Voting Shares pursuant to the Redemption Right, our Call Right, the Hybrid Redemption Right or other transfers of B.V.

Non-Voting Shares could cause HMH B.V. to be treated as a publicly traded partnership. Applicable U.S. Treasury regulations provide for certain safe harbors from treatment as a publicly traded partnership, and we intend to operate such that one or more such safe harbors shall apply. For example, we intend to limit the number of shareholders of HMH B.V., and the HMH B.V. Partnership Agreement, which will be entered into in connection with the closing of this offering, will provide for limitations on the ability of the HMH B.V. shareholders to transfer their B.V. Shares and will provide us, as owner of all B.V. Voting Shares, with the right to impose restrictions (in addition to those already in place) on the ability of shareholders of B.V. Non-Voting Shares to cause HMH B.V. or us to acquire or directly cancel their B.V. Non-Voting Shares pursuant to the Redemption Right or the Hybrid Redemption Right to the extent we believe it is necessary to ensure that HMH B.V. will continue to be treated as a partnership for U.S. federal income tax purposes. From time to time, the U.S. Congress has considered legislation to change the tax treatment of partnerships, and there can be no assurance that any such legislation will not be enacted or, if enacted, will not be adverse to us.

If HMH B.V. were to become a publicly traded partnership, significant tax inefficiencies might result for us and for HMH B.V., including as a result of our inability to file a consolidated U.S. federal income tax return with HMH B.V. In addition, we would no longer have the benefit of certain increases in tax basis covered under the Tax Receivable Agreement, and we would not be able to recover any payments previously made by us under the Tax Receivable Agreement, even if the corresponding tax benefits (including any claimed increase in the tax basis of HMH B.V.’s assets) were subsequently determined to have been unavailable.

If we were deemed to be an investment company under the Investment Company Act of 1940, as amended (the “1940 Act”), applicable restrictions could make it impractical for us to continue our business as contemplated and could have a material adverse effect on our business, prospects, financial condition, results of operations and cash flows.

Under Sections 3(a)(1)(A) and (C) of the 1940 Act, a company generally will be deemed to be an “investment company” for purposes of the 1940 Act if it (i) is, or holds itself out as being, engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities or (ii) is engaged, or proposes to engage, in the business of investing, reinvesting, owning, holding or trading in securities and it owns or proposes to acquire investment securities having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis. We do not believe that we are an “investment company,” as such term is defined in either of those sections of the 1940 Act.

As the owner of all of the B.V. Voting Shares, we will control and manage HMH B.V. On that basis, we believe that our interest in HMH B.V. is not an “investment security” under the 1940 Act. Therefore, we have less than 40% of the value of our total assets (exclusive of U.S. government securities and cash items) in “investment securities.” However, if we were to lose the right to manage and control HMH B.V., interests in HMH B.V. could be deemed to be “investment securities” under the 1940 Act.

We intend to conduct our operations so that we will not be deemed to be an investment company. However, if we were deemed to be an investment company, restrictions imposed by the 1940 Act, including limitations on our capital structure and our ability to transact with affiliates, could make it impractical for us to continue our business as contemplated and could have a material adverse effect on our business, prospects, financial condition, results of operations and cash flows.

You will incur immediate and substantial dilution.

Prior stockholders have paid substantially less per share of our Class A common stock than the price in this offering. The assumed initial public offering price per share of our Class A common stock will be substantially higher than the pro forma net tangible book value per share of outstanding Class A common stock prior to

completion of this offering. Based on our as adjusted pro forma net tangible book value as of March 31, 2025, and upon the issuance and sale of shares of our Class A common stock by us at an assumed initial public offering price of $ per share (which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus), if you purchase our Class A common stock in this offering, you will pay more for your shares than the amounts paid by our existing stockholders for their shares and you will suffer immediate dilution of $ per share. Dilution is the amount by which the offering price paid by purchasers of our Class A common stock in this offering will exceed the as adjusted pro forma net tangible book value per share of our Class A common stock upon completion of this offering. If the underwriters exercise their option to purchase additional shares, you will experience additional dilution. You may experience additional dilution in connection with any LTI Awards that may vest in connection with this offering. See “Dilution.”

Our stock price may change significantly following this offering, and you may not be able to resell shares of our Class A common stock at or above the price you paid or at all, and you could lose all or part of your investment as a result.

We and the underwriters will negotiate to determine the initial public offering price. You may not be able to resell your shares at or above the initial public offering price due to a number of factors such as those listed in “—Risks related to our business” and the following:

•

results of operations that vary from the expectations of securities analysts and investors;

•

results of operations that vary from those of our competitors;

•

changes in expectations as to our future financial performance, including financial estimates and investment recommendations by securities analysts and investors;

•

changes in economic conditions for companies in our industry;

•

changes in market valuations of, or earnings and other announcements by, companies in our industry;

•

declines in the market prices of stocks generally, particularly those of companies in our industry;

•

additions or departures of key management personnel;

•

strategic actions by us or our competitors;

•

announcements by us, our competitors or our suppliers of significant contracts, price reductions, new products or technologies, acquisitions, joint marketing relationships, joint ventures, other strategic relationships or capital commitments;

•

changes in preference of our customers;

•

changes in general economic or market conditions or trends in our industry or the economy as a whole;

•

changes in business or regulatory conditions;

•

future sales of our Class A common stock or other securities by us or the Principal Stockholders, or the perception that such sales may occur;

•

investor perceptions of or the investment opportunity associated with our Class A common stock relative to other investment alternatives;

•

the public’s response to press releases or other public announcements by us or third parties, including our filings with the SEC;

•

announcements relating to litigation or governmental investigations;

•

guidance, if any, that we provide to the public, any changes in this guidance or our failure to meet this guidance;

•

the development and sustainability of an active trading market for our stock;

•

changes in accounting principles; and

•

other events or factors, including those resulting from IT system failures and disruptions, natural disasters, war, acts of terrorism, pandemics or responses to these events.

Furthermore, the stock market may experience extreme volatility that, in some cases, may be unrelated or disproportionate to the operating performance of particular companies. These broad market and industry fluctuations may adversely affect the market price of our Class A common stock, regardless of our actual operating performance. In addition, price volatility may be greater if the public float and trading volume of our Class A common stock is low.

In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If we were to become involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from our business regardless of the outcome of such litigation.

If securities or industry analysts do not publish or cease publishing research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.

The trading market for our Class A common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not currently have and may never obtain research coverage by securities and industry analysts. If no or few securities or industry analysts commence coverage of us, the trading price for our Class A common stock would be negatively impacted. In the event we obtain securities or industry analyst coverage, if any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model or our stock performance, or if our results of operations fail to meet the expectations of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

Taking advantage of the reduced disclosure requirements applicable to “emerging growth companies” may make our Class A common stock less attractive to investors.

We qualify as an “emerging growth company” as defined in the JOBS Act. An emerging growth company may take advantage of certain reduced reporting and other requirements that are otherwise applicable generally to public companies. Pursuant to these reduced disclosure requirements, emerging growth companies are not required to, among other things, comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, provide certain disclosures regarding executive compensation, hold stockholder advisory votes on executive compensation or obtain stockholder approval of any golden parachute payments not previously approved. In addition, emerging growth companies have longer phase-in periods for the adoption of new or revised financial accounting. We will cease to be an emerging growth company upon the earliest of (i) the last day of the fiscal year following the fifth anniversary of this offering; (ii) the last day of the fiscal year in which we have equal to or more than $1.235 billion in annual revenue; (iii) the date on which we issue more than $1 billion of non-convertible debt over a three-year period; or (iv) the date on which we become a “large accelerated filer” (the fiscal year-end on which the total market value of our common equity securities held by non-affiliates is $700 million or more as of June 30).

We intend to take advantage of all of the reduced reporting requirements and exemptions, including the longer phase-in periods for the adoption of new or revised financial accounting standards under Section 107 of the JOBS Act, until we are no longer an emerging growth company. If we were to subsequently elect instead to comply with these public company effective dates, such election would be irrevocable pursuant to Section 107 of the JOBS Act.

Our election to use the phase-in periods permitted by this election may make it difficult to compare our financial statements to those of non-emerging growth companies and other emerging growth companies that have opted out of the longer phase-in periods under Section 107 of the JOBS Act and who will comply with new or revised financial accounting standards. We cannot predict if investors will find our Class A common stock less attractive because we will rely on these exemptions. If some investors find our Class A common stock less attractive as a result, there may be a less active trading market for our Class A common stock, and our Class A common stock price may be more volatile. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies.

We will incur significantly increased costs and become subject to additional regulations and requirements as a result of becoming a public company, and our management will be required to devote substantial time to new compliance matters, which could lower our profits or make it more difficult to run our business.

As a public company, we will incur significant legal, regulatory, finance, accounting, investor relations and other expenses that we have not incurred as a private company, including costs associated with public company reporting requirements. As a result of having publicly traded Class A common stock, we will also be required to comply with, and incur costs associated with such compliance with, the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), as well as rules and regulations implemented by the SEC and the exchange on which we list our shares. The expenses incurred by public companies generally for reporting and corporate governance purposes have been increasing. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. Our management will need to devote a substantial amount of time to ensure that we comply with all of these requirements, diverting the attention of management away from revenue-producing activities. These laws and regulations also could make it more difficult or costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors or our board committees or as our executive officers. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of our Class A common stock, fines, sanctions and other regulatory action and potentially civil litigation.

Future sales, or the perception of future sales, by us or our existing stockholders in the public market following this offering could cause the market price for our Class A common stock to decline.

After this offering, the sale of shares of our Class A common stock in the public market, or the perception that such sales could occur, including sales by the Principal Stockholders, could harm the prevailing market price of shares of our Class A common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

Upon completion of this offering and prior to giving effect to the vesting of any LTI Awards that may vest in connection with this offering and any future redemptions of B.V. Non-Voting Shares (and, if applicable, acquisitions of Mercury HoldCo Inc. shares) pursuant to the Exchange Agreement, we will have a total of shares of our Class A common stock outstanding ( shares if the underwriters exercise in full

their option to purchase additional shares of Class A common stock) and shares of Class B common stock ( shares if the underwriters exercise in full their option to purchase additional shares of Class A common stock). Of such outstanding shares, the shares of Class A common stock sold in this offering (or shares of Class A common stock if the underwriters exercise in full their option to purchase additional shares of Class A common stock) will be freely tradable without restriction or further registration under the Securities Act, except that any shares held by our affiliates, as that term is defined under Rule 144 under the Securities Act (“Rule 144”), including our directors, director nominees, executive officers and other affiliates (including the Principal Stockholders), may be sold only in compliance with the limitations described in “Shares eligible for future sale.”

The shares of Class A common stock beneficially held by the Principal Stockholders and certain of our directors, director nominees and executive officers after this offering, representing % of the total aggregate number of Class A common stock and Class B common stock outstanding following this offering (without giving effect to any purchases that certain of our directors, director nominees and executive officers may make through the Directed Share Program), will be “restricted securities” within the meaning of Rule 144 and subject to certain restrictions on resale. Restricted securities may be sold in the public market only if they are registered under the Securities Act or are sold pursuant to an exemption from registration such as Rule 144, as described in “Shares eligible for future sale.”

In connection with this offering, we, our directors, director nominees and executive officers and the Principal Stockholders will sign lock-up agreements with the underwriters that will, subject to certain exceptions, restrict the disposition of, or hedging with respect to, the shares of our Class A common stock or securities convertible into or exchangeable for shares of Class A common stock, each held by them for 180 days following the date of this prospectus, except with the prior written consent of each of J.P. Morgan Securities LLC, Piper Sandler & Co. and Evercore Group L.L.C. See “Underwriting” for a description of these lock-up agreements. J.P. Morgan Securities LLC, Piper Sandler & Co. and Evercore Group L.L.C., on behalf of the underwriters, may, in their sole discretion, release all or some portion of the shares subject to the 180-day lock-up agreements prior to the expiration of such period.

Upon the expiration of the lock-up agreements described above, all of such shares will be eligible for resale in a public market, subject, in the case of shares held by our affiliates, to volume, manner of sale and other limitations under Rule 144. We expect that the Principal Stockholders and their respective affiliates may be considered our affiliates based on their respective expected share ownership (consisting of shares of Class A common stock and shares of Class B common stock beneficially owned by affiliates of the Principal Stockholders), as well as their board designation rights. Certain other of our stockholders may also be considered affiliates at that time.

In connection with this offering, we plan to enter into the Registration Rights Agreement with the Principal Stockholders. We expect that the Registration Rights Agreement will contain provisions by which we agree to register under the federal securities laws the offer and resale of shares of our Class A common stock by the Principal Stockholders, their affiliates or their respective permitted transferees. See “Certain relationships and related party transactions—Registration Rights Agreement.” By exercising their registration rights and selling a large number of shares of Class A common stock, the Principal Stockholders could cause the prevailing market price of our Class A common stock to decline. Following completion of this offering, the shares of Class A common stock (including the number of shares of Class A common stock that the Principal Stockholders may receive in exchange for an equal number of B.V. Non-Voting Class A Shares, B.V. Non-Voting Class B Shares and shares of our Class B common stock) covered by registration rights would represent % of our total Class A common stock outstanding (or % if the underwriters exercise in full their option to purchase additional shares of Class A common stock). Registration of any of these outstanding shares of Class A common stock would result in such shares becoming freely tradable without compliance with Rule 144 upon effectiveness of

the registration statement. See “Shares eligible for future sale.” It is anticipated that the Principal Stockholders may exercise their registration rights to effect additional public sales of our Class A common stock.

As soon as practicable following this offering, we may file one or more registration statements on Form S-8 under the Securities Act to register the shares of our Class A common stock that may be reserved for issuance under any long-term incentive plan that may be adopted. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market. We expect that any initial registration statement on Form S-8 will cover shares of our Class A common stock.

As restrictions on resale end, or if the Principal Stockholders exercise their registration rights, the market price of our shares of Class A common stock could drop significantly if the holders of these shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of our shares of Class A common stock or other securities.

In the future, we may also issue our securities in connection with investments or acquisitions. The amount of shares of our Class A common stock issued in connection with an investment or acquisition could constitute a material portion of our then-outstanding shares of our Class A common stock. Any issuance of additional securities in connection with investments or acquisitions may result in additional dilution to you.

Anti-takeover provisions in our organizational documents could delay or prevent a change of control.

Certain provisions of our amended and restated certificate of incorporation and our amended and restated bylaws, once adopted, may have an anti-takeover effect and may delay, defer or prevent a merger, acquisition, tender offer, takeover attempt or other change of control transaction that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by our stockholders.

These provisions will, among other things:

•

authorize the issuance of undesignated preferred stock, the terms of which may be established and the shares of which may be issued without stockholder approval, and which may include super voting, special approval, dividend or other rights or preferences superior to the rights of our Class A common stock;

•

in the event that the Principal Stockholders are no longer entitled to designate for nomination at least three directors to our board of directors pursuant to the Stockholders’ Agreement, prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;

•

provide that our board of directors is expressly authorized to make, alter or repeal our amended and restated bylaws; and

•

establish advance notice requirements for nominations of directors or for proposing matters that can be acted upon by stockholders at stockholder meetings.

These anti-takeover provisions could make it more difficult for a third party to acquire us, even if the third party’s offer may be considered beneficial by many of our stockholders. As a result, our stockholders may be limited in their ability to obtain a premium for their shares in such circumstances. See “Description of capital stock.”

In addition, certain change of control events could have the effect of accelerating the payment due under the Tax Receivable Agreement, which could be substantial and accordingly serve as a disincentive to a potential acquirer of us. Please see “—In certain cases, payments under the Tax Receivable Agreement may be

accelerated and significantly exceed the actual benefits, if any, we realize in respect of the tax attributes subject to the Tax Receivable Agreement.” Further, certain of our outstanding debt agreements place restrictions on a change of control. See “Management’s discussion and analysis of financial condition and results of operations—Liquidity and capital resources—Debt agreements—Revolver.”

Our board of directors will be authorized to issue and designate shares of our preferred stock without stockholder approval.

Our amended and restated certificate of incorporation will authorize our board of directors, without the approval of our stockholders, to issue shares of our preferred stock, subject to limitations prescribed by applicable law, rules and regulations and the provisions of our amended and restated certificate of incorporation, as shares of preferred stock in series, to establish from time to time the number of shares to be included in each such series and to fix the designation, powers, preferences and rights of the shares of each such series and the qualifications, limitations or restrictions thereof. The powers, preferences and rights of these series of preferred stock may be senior to or on parity with our Class A common stock, which may reduce its value.

Our amended and restated bylaws will designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our amended and restated bylaws will provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers, employees or stockholders to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law (the “DGCL”), our amended and restated certificate of incorporation or our amended and restated bylaws or (iv) any action asserting a claim against us that is governed by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. The federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under U.S. federal securities laws, including the Securities Act and the Exchange Act. However, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce a duty or liability created by the Securities Act or the rules and regulations thereunder and, accordingly, we cannot be certain that a court would enforce such provision. Any person or entity purchasing or otherwise acquiring or holding any interest in shares of our capital stock will be deemed to have notice of, and consented to, the provisions of our amended and restated bylaws described in the preceding sentences. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of our amended and restated bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition and results of operations.

Dividends may not be declared or paid to holders of our Class A common stock in the foreseeable future, and our existing debt agreements place certain restrictions on our ability to do so.

However, our dividend policy is within the discretion of our board of directors and will depend upon then-existing conditions, including our results of operations, financial condition, capital requirements, investment opportunities, statutory or contractual restrictions on our ability to pay dividends and other factors our board of directors may deem relevant. See “Dividend policy.” In addition, our existing debt agreements place, and we expect our future debt agreements will place, certain restrictions on our ability to pay cash dividends on our Class A common stock. Consequently, unless and until our board of directors decides to declare a dividend, your only opportunity to achieve a return on your investment is if the price of our Class A common stock appreciates. There is no guarantee that the price of our Class A common stock that will prevail in the market will ever exceed the price that you pay in this offering.

Use of proceeds

We expect to receive $ million of net proceeds (assuming the midpoint of the price range set forth on the cover page of this prospectus) from the sale of Class A common stock by us in this offering, after deducting underwriting discounts and commissions and estimated offering expenses payable by us. If the underwriters exercise in full their option to purchase additional shares of Class A common stock from us, we estimate that the net proceeds will be $ million, after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to (i) use $ million of the net proceeds from this offering to pay the cash consideration portion of the purchase price to purchase an aggregate B.V. Voting Class A Shares and B.V. Voting Class B Shares from Baker Hughes and/or Akastor pursuant to the corporate reorganization (see “Corporate reorganization”) and (ii) contribute all of the remaining net proceeds from this offering to HMH B.V. in exchange for a number of B.V. Voting Class A Shares and B.V. Voting Class B Shares such that the number of B.V. Voting Class A Shares and B.V. Voting Class B Shares, respectively, held by us (taking into account the B.V. Voting Class A Shares and B.V. Voting Class B Shares acquired by us from the Principal Stockholders pursuant to the corporate reorganization) equals the number of shares of Class A common stock sold by us in the offering. HMH B.V. intends to use $ million of the net proceeds received by it to repay all of the outstanding principal and accrued and unpaid interest under the Shareholder Loans from Baker Hughes Holdings LLC and Akastor AS, which totaled $134.6 million as of March 31, 2025, and any remaining amounts for general corporate purposes, which may include funding for acquisitions, working capital requirements, capital expenditures and the repayment, refinancing, redemption or repurchase of indebtedness or other securities.

The Shareholder Loans mature on the earliest to occur of October 1, 2026 or a liquidation event (as defined in the Shareholder Loan Agreement) such as the consummation of this offering. As of March 31, 2025, the total amount of principal and accrued and unpaid interest outstanding under the Shareholder Loans was $134.6 million, which included $105.9 million outstanding under the Baker Hughes Shareholder Loan (as defined herein) and $28.7 million outstanding under the Akastor Shareholder Loan (as defined herein). The Shareholder Loans bear interest at a rate of 8.0% per annum. See “Management’s discussion and analysis of financial condition and results of operations—Liquidity and capital resources—Debt agreements—Shareholder Loans” and “Certain relationships and related party transactions—Shareholder Loans.”

A $1.00 increase or decrease in the assumed initial public offering price of $ per share would cause the net proceeds from this offering, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, to increase or decrease, respectively, by $ million, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same. If the proceeds increase due to a higher initial public offering price or due to the issuance of additional shares, we will use the additional net proceeds for general corporate purposes. If the proceeds decrease due to a lower initial public offering price or a decrease in the number of shares issued, we will contribute fewer net proceeds to HMH B.V., which may reduce by a corresponding amount the net proceeds directed to repay the Baker Hughes Shareholder Loan and the Akastor Shareholder Loan.

The expected use of net proceeds from this offering represents our intentions based upon our present plans and business conditions. We cannot predict with certainty all of the particular uses for the proceeds from this offering or the amounts that we will actually spend on the uses set forth above. Accordingly, our management will have significant flexibility in applying the net proceeds from this offering. The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business.

Dividend policy

The declaration and payment of dividends by us will be at the sole discretion of our board of directors. We currently intend to retain future earnings, if any, to finance the growth and development of our business. However, our dividend policy is within the discretion of our board of directors and will depend upon then-existing conditions, including our results of operations, financial condition, capital requirements, investment opportunities, statutory or contractual restrictions on our ability to pay dividends and other factors our board of directors may deem relevant. In addition, our existing debt agreements place, and we expect our future debt agreements will place, certain restrictions on our ability to pay cash dividends on our Class A common stock. See “Risk factors—Risks related to this offering and ownership of our Class A common stock—Dividends may not be declared or paid to holders of our Class A common stock in the foreseeable future, and our existing debt agreements place certain restrictions on our ability to do so.” Consequently, unless and until our board of directors decides to declare a dividend, your only opportunity to achieve a return on your investment is if the price of our Class A common stock appreciates.

Capitalization

The following table sets forth our cash and cash equivalents and capitalization as of March 31, 2025:

•

on an actual basis as of March 31, 2025 for our predecessor;

(2)

The as adjusted column includes the HMH B.V. interests not owned by us, which represents % of the B.V. Shares. The Principal Stockholders will hold a % equity interest in HMH B.V. HMH Inc. will hold a % equity interest in HMH B.V.

Dilution

Purchasers of our Class A common stock in this offering will experience immediate and substantial dilution in the net tangible book value (tangible assets less total liabilities) per share of our Class A common stock for accounting purposes. Our pro forma net tangible book value as of March 31, 2025 after giving pro forma effect to the corporate reorganization was $ million, or $ per share of Class A common stock.

Pro forma net tangible book value per share is determined by dividing our pro forma net tangible book value, or total tangible assets less total liabilities, by our shares of Class A common stock that will be outstanding immediately prior to the closing of this offering, including giving effect to the corporate reorganization (assuming that 100% of our Class B common stock has been cancelled in connection with a redemption of B.V. Non-Voting Shares for Class A common stock). Assuming an initial public offering price of $ per share (which is the midpoint of the price range set forth on the cover page of this prospectus), after giving pro forma effect to the sale of the shares in this offering and further assuming the receipt of the estimated net proceeds (after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us and the application of such proceeds as described in the as adjusted column in “Capitalization”), our as adjusted pro forma net tangible book value as of March 31, 2025 would have been $ million, or $ per share. This represents an immediate increase in the pro forma net tangible book value of $ per share to our existing investors and an immediate dilution to new investors purchasing shares in this offering of $ per share, resulting from the difference between the assumed offering price and the as adjusted pro forma net tangible book value after giving effect to the corporate reorganization and this offering. The following table illustrates the per share dilution to new investors purchasing shares in this offering (assuming that 100% of our Class B common stock has been cancelled in connection with a redemption of B.V. Non-Voting Shares for Class A common stock):


Assumed initial public offering price per share		$
Pro forma net tangible book value per share as of March 31, 2025 after giving effect to the corporate reorganization (before this offering)	$
Increase per share attributable to new investors in this offering	$

As adjusted pro forma net tangible book value per share (after giving effect to the corporate reorganization and this offering)		$

Dilution in pro forma net tangible book value per share to new investors in this offering(1)		$

(1)

If the initial public offering price were to increase or decrease by $1.00 per share, then dilution in pro forma net tangible book value per share to new investors in this offering would equal $ or $ , respectively.

The following table summarizes, on an adjusted pro forma basis as of March 31, 2025, the total number of shares of Class A common stock owned by our existing investors (assuming that 100% of our Class B common stock has been cancelled in connection with a redemption of B.V. Non-Voting Shares for Class A common stock) and to be owned by new investors, the total consideration paid and the average price per share paid by our existing investors and to be paid by new investors in this offering at $ per share, calculated before deduction of estimated underwriting discounts and commissions.

The data in the table excludes the shares of Class A common stock that may be reserved for issuance under any long-term incentive plan that may be adopted.

Each $1.00 increase (decrease) in the initial public offering price of $ per share of Class A common stock would increase (decrease) the total consideration paid by new investors in this offering and the total consideration paid by all holders of Class A common stock by $ million, assuming the number of shares of Class A common stock offered by us, as set forth on the cover page of this prospectus, remains the same, after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.

If the underwriters exercise in full their option to purchase additional shares of Class A common stock, the number of shares of Class A common stock being offered in this offering will be increased to , with such additional shares representing % of the total number of shares of Class A common stock.

Management’s discussion and analysis of financial condition and results of operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with “Summary—Summary historical and pro forma financial data” and the accompanying financial statements and related notes thereto included elsewhere in this prospectus.

Company overview

•

Sales of projects and products. This includes (i) comprehensive drilling equipment packages containing a full suite of components needed for a newbuild or reactivated drilling rig and (ii) individual or grouped components of drilling and pressure control equipment that facilitate customers maintaining and upgrading their existing fleet. During the three months ended March 31, 2025 and the year ended December 31, 2024, we derived 27.6% and 27.2%, respectively, of our revenue from sales of projects and products.

•

Sales of spare parts. This includes replacement parts for installed equipment used in oil and gas drilling operations. During the three months ended March 31, 2025 and the year ended December 31, 2024, we derived 30.3% and 29.4%, respectively, of our revenue from sales of spare parts.

market. As a result, offshore operators require highly engineered equipment and technical support services to keep their operations running safely, efficiently and productively. We believe that we are well-positioned to continue supporting and building our presence in the offshore drilling market as a result of our full, integrated suite of mission-critical drilling solutions, highly technical expertise, aftermarket services offerings and long experience providing and maintaining equipment in this industry.

HSSE is a key component of our organizational culture, and we strive to cultivate an HSSE-focused mindset among our employees and in connection with our activities. Our employees are expected to advance our corporate HSSE values and principles, including caring for the environment and prioritizing the safety and well-being of our employees and other stakeholders.

We have an asset-light business model through the leveraging of our existing operating footprint and OEM business model and are well positioned to grow and scale our business with low incremental investment and capital expenditures. During the three months ended March 31, 2025, our net income was $5.9 million (or 3.0% of revenue) (as compared to net income of $8.5 million during the three months ended March 31, 2024) and our Adjusted EBITDA was $29.9 million (or 15.1% of revenue), while capital expenditures, including development costs, represented only 1.2% of revenue. During the year ended December 31, 2024, our net income was $52.0 million (or 6.2% of revenue) (as compared to net income of $17.4 million during the year ended December 31, 2023) and our Adjusted EBITDA was $158.4 million (or 18.8% of revenue), while capital expenditures, including development costs, represented only 2.2% of revenue. Having an asset-light business allows us to generate a strong Adjusted ROCE, a metric that we use to evaluate the profitability of our capital employed in our business operations. During the three months ended March 31, 2025 and the year ended December 31, 2024, our Adjusted ROCE was 3.5% and 19.7%, respectively. Adjusted EBITDA and Adjusted ROCE are non-GAAP financial measures. Please see “Summary—Summary historical and pro forma financial data—Non-GAAP financial measures” for the definitions of Adjusted EBITDA and Adjusted ROCE and a reconciliation of Adjusted EBITDA and Adjusted ROCE to our most directly comparable financial measures calculated and presented in accordance with GAAP.

Our predecessor and HMH Inc.

HMH Inc. was formed on April 29, 2024, and has not conducted and will not conduct any material business operations prior to the completion of the transactions described under “Corporate reorganization” other than certain activities related to this offering. Our predecessor consists of HMH B.V. and its subsidiaries on a consolidated basis. Unless otherwise indicated, the historical consolidated financial information included in this prospectus presents the historical financial information of HMH B.V. Historical consolidated financial information is not indicative of the results that may be expected in any future periods. For more information, please see the historical consolidated financial statements and related notes thereto included elsewhere in this prospectus and “—Factors affecting the comparability of our results of operations.”

Market factors and trends

Oil and gas play a critical role in enabling modern society to function and providing increased standards of living to the global population. We believe that oil and gas will continue to play a leading role in the future global energy mix. While the world will take the needed efforts to diversify its energy supply into renewables and more sustainable forms of energy, including nuclear, the IEA estimates that oil and gas will nonetheless comprise 45% of global energy supply in 2050 and that global energy consumption is expected to increase to 533 exajoule (“EJ”) by 2050, a 20% increase from 2023 levels and a 41% increase from 2010 levels.

Our business is driven by the number of drilling rigs working globally onshore and offshore (particularly those drilling rigs on which our equipment is installed), which in turn is driven by oil and gas demand, levels of global drilling activity and spending by E&P operators associated with supplying oil and gas. As demand for contracted drilling rigs increases, our customers may seek to replace existing equipment that is in need of major refurbishment or no longer operational, upgrade the capacities of their existing drilling rigs with our highly engineered, integrated drilling solutions or retrofit a new comprehensive drilling package or entire newbuild drilling rig. We provide ongoing aftermarket services and spare part sales on drilling rigs with our installed equipment, as well rigs with equipment from other OEMs, allowing us to capture recurring revenues throughout the lifecycle of a drilling rig.

The last build cycle for offshore drilling rigs ended in 2015 when E&P operators shifted spending to short-cycle onshore shale from offshore, leading to an oversupply of floater and jack-up rigs, sending the offshore drilling industry into a prolonged downturn. This led to chronic underinvestment, which, when combined with declining rates on existing wells, created upward pressure on day rates and led to increases in activity in 2019. The decrease in customer spending as a result of the emergence of the COVID-19 pandemic in 2020 and the resulting decline in oil and gas demand caused our customers to take rigs out of service as offshore drilling activity contracted. Beginning in 2021 with the gradual reopening of supply chains, however, the offshore oil and gas industry had largely returned to its pre-COVID recovery trend.

According to Rystad Energy, after years of underinvestment, global greenfield and brownfield oil and gas capital expenditures are projected to be over $700 billion in each of 2025, 2026 and 2027, an increase of almost 60% as compared to 2020. As global capital expenditures for the oil and gas industry increase, the offshore rig market is also approaching activity levels not seen in nearly a decade. Rystad Energy forecasts a compounded annual growth rate of over 6% for floater rigs between 2024 and 2027, and offshore production is expected to grow 16% between 2024 and 2030. Rystad Energy also expects to see offshore deepwater production as the

main contributor to global non-OPEC oil supply beyond 2027 as spending shifts towards offshore in response to the relative underinvestment in long-cycle, high-volume offshore developments over the past decade. Such increase in oil and gas exploration and drilling activity, particularly offshore, is expected to result in increased demand for our equipment, aftermarket services and spare parts.

Demand related to onshore oil and gas drilling activity tends to be shorter cycle and regionally focused as each market may have specific dynamics that vary from location to location. Since the cyclical trough in activity during the last commodity price decline and COVID-19, the total number of active land rigs has increased and, in the key Middle East market, the demand for modern, high-spec land rigs capable of supporting complex drilling operations has resulted in newbuild opportunities. In the North American unconventional market, efficiency gains in drilling and completion activity have resulted in production increasing without a corresponding increase in rig counts—implying each active rig is drilling more wells and more footage in a given period than previously. This increased cadence of drilling activity in challenging subsurface environments and more complex, longer lateral wells create increased wear-and-tear on equipment, resulting in additional demand for our products, aftermarket services and spare parts.

We have an overall positive outlook for global oil and gas activity, with a specific emphasis on tailwinds in global offshore E&P spending and onshore E&P spending in the Middle East. We believe that increased E&P activity in the oil and gas industry, particularly offshore, will be required to meet expected growth in global demand. We believe that current low levels of E&P capital spending are not sustainable, and the E&P industry will require more capital investment in order to increase production capacity to meet near-term and long-term demand for oil and gas.

Tariffs and trading relationships

In April 2025, the U.S. government announced a baseline tariff of 10% on products imported from all countries and an additional individualized reciprocal tariff on the countries with which the United States has the largest trade deficits. Increased tariffs by the United States have led and may continue to lead to the imposition of retaliatory tariffs by foreign jurisdictions. Additionally, the U.S. government has announced and rescinded multiple tariffs on several foreign jurisdictions, which has increased uncertainty regarding the ultimate effect of the tariffs on economic conditions. Current uncertainties about tariffs and their effects on trading relationships may affect costs for and availability of raw materials and component parts or contribute to inflation in the markets in which we operate. Although we are continuing to monitor the economic effects of such announcements, as well as opportunities to mitigate their related impacts, costs and other effects associated with the tariffs remain uncertain.

Description of certain components of financial data

Revenues

We generate our revenue primarily from three broadly categorized offerings: (i) product revenue, which comprises revenue from sales of projects and products and includes (a) comprehensive drilling equipment packages containing a full suite of components needed for a newbuild or reactivated drilling rig and (b) individual or grouped components of drilling and pressure control equipment that facilitate customers maintaining and upgrading their existing fleet, (ii) service revenue, which comprises aftermarket services relating to installed equipment and integrated digital solutions, and (iii) spare parts revenue, which includes replacement spare parts. We also generate our revenue from related parties via sales to Baker Hughes, which primarily consists of sales of products and services consistent in nature with those of external parties.

During the three months ended March 31, 2025, we derived 27.6% of our revenue from sales of projects and products, 42.1% from aftermarket services and 30.3% from sales of spare parts. During 2024, we derived 27.2% of our revenue from sales of projects and products, 43.4% from aftermarket services and 29.4% from sales of spare parts. We are a global company, with 34 physical locations in 16 countries and with sales in over 90 countries in 2024.

Cost of sales

Our cost of sales consists of costs related to the manufacturing and procurement of our products and projects in addition to the costs of our aftermarket services and spare parts. Cost of sales related to the manufacturing and procurement of our products and projects includes the cost of components sourced from third-party suppliers and direct and indirect costs to manufacture and supply products and projects, including labor, materials, machine time, lease expense related to our manufacturing facilities, freight and other variable manufacturing costs. Cost of services includes personnel expenses for our field service organization, lease expense related to our operations facilities, materials, vehicle expenses and freight and other variable costs. Cost of sales related to spare parts includes the cost of the spare parts inventory, personnel expenses, lease expense related to our facilities, inventory management expenses, freight and other variable costs.

Selling, general and administrative expenses

Selling, general and administrative expenses consist of costs such as sales and marketing, general corporate overhead, compensation expense, IT expenses, safety and environmental expenses, insurance costs, legal expenses and other related administrative functions. As a result of becoming a public company, we anticipate incurring incremental general and administrative expenses relating to expenses associated with SEC reporting requirements, including annual and quarterly reports, tax return preparation and dividend expenses, Sarbanes-Oxley Act compliance expenses, expenses associated with listing on Nasdaq, independent auditor fees, legal expenses and investor relations expenses. These incremental general and administrative expenses are not reflected in our predecessor’s historical financial statements included elsewhere in this prospectus.

Research and development expenses

Research and development expenses consist of costs that are incurred in connection with the development of new cutting-edge technologies and solutions and the innovation of existing product and service offerings. Such costs include both the utilization of our employees, facilities and resources to create and develop new ideas and products and the engagement of third parties to perform development activities under our coordination and management.

Depreciation and amortization

Depreciation and amortization expense consists of depreciation related to our tangible assets, including investments in property and equipment, and amortization of intangible assets, including identified intangible assets step up related to the formation of HMH B.V. and acquisition purchase price accounting. Depreciation and amortization expense is included in the consolidated statements of income within cost of sales and selling, general and administrative expenses.

Other operating expenses (income), net

During the three months ended March 31, 2025 and the year ended December 31, 2024, other operating expenses (income), net consisted of additional de minimis incidental operating expenses incurred by the business. See our predecessor’s historical financial statements and related notes thereto included elsewhere in this prospectus for further information.

Other non-operating income, net

Other non-operating income, net consists of income on disposal or impairments of long-lived assets as well as other miscellaneous charges that management deems to not be part of our core business.

Foreign currency (gain) loss, net

Foreign currency (gain) loss, net consists of net gains or losses resulting from a change in exchange rates between the functional currency and the currency in which a foreign currency transaction is denominated. Our foreign subsidiaries, whose functional currency is the local currency, conduct a portion of their operations in U.S. dollars. As a result, these subsidiaries hold significant monetary assets denominated in U.S. dollars. These monetary assets are subject to changes in exchange rates between the U.S. dollar and the local currency.

Interest expense, net

Interest expense, net primarily consists of interest expense associated with the Revolver and the Senior Secured Bonds.

Income tax expense

Income tax expense consists of income tax expenses in the various jurisdictions in which we operate. We are subject to income taxes in both the United States and foreign jurisdictions in which we operate. Differences between our effective tax rate and the U.S. federal income tax rate are primarily due to state taxes, foreign jurisdiction rate differences, permanent differences between book and tax income and change in valuation allowance.

How we evaluate our results of operations

We use a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our results of operations and profitability and include:

•

Revenues. Our revenues are generated primarily from (i) projects and products, (ii) aftermarket services and (iii) spare parts. One of our measures of financial performance is the amount of revenue generated quarterly and annually as revenue is an indicator of our overall business growth.

•

Operating Income. We track operating income on an absolute dollar basis. One of our measures of financial performance is the amount of operating income generated quarterly and annually, as operating income is an indicator of profit derived from our core business operations.

•

Net Income. We track net income on an absolute dollar basis and as a percentage of revenue. One of our measures of financial performance is the amount of net income generated quarterly and annually as net income is an indicator of our overall profitability.

•

Adjusted EBITDA and Adjusted EBITDA Margin. We use Adjusted EBITDA and Adjusted EBITDA Margin (each, a non-GAAP measure) as one of the indicators to evaluate and compare the results of our operations from period to period by removing the effect of our capital structure and certain non-recurring items. We define Adjusted EBITDA as net income before interest expense, net, income tax expense, depreciation and amortization and certain non-recurring items that we do not consider to be indicative of our ongoing operating performance such as, but not limited to, IT system implementation, restructuring expenses and foreign currency transaction (gain) loss. We track Adjusted EBITDA on an absolute dollar basis and as a percentage of revenue, which we refer to as Adjusted EBITDA Margin. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by revenue. We believe that Adjusted EBITDA is a supplemental measurement tool used by analysts and investors to evaluate overall operating performance, ability to pursue and service possible debt opportunities and possible future investment opportunities. In addition, we believe that Adjusted EBITDA Margin is a supplemental measurement tool used by analysts and investors to evaluate

profitability of sales. Adjusted EBITDA does not represent funds available for our discretionary use and is not intended to represent or to be used as a substitute for net income, as measured under GAAP. The items excluded from Adjusted EBITDA and Adjusted EBITDA Margin, but included in the calculation of reported net income, are significant components of the consolidated statements of income and must be considered in performing a comprehensive assessment of overall financial performance. For a reconciliation of Adjusted EBITDA and Adjusted EBITDA Margin to net income, the most directly comparable GAAP measure, see “—Comparison of non-GAAP financial measures.”

•

Free Cash Flow. We use Free Cash Flow (a non-GAAP measure) to evaluate our liquidity to provide flexibility and optionality to achieve our broader capital allocation strategy. We define Free Cash Flow as cash flow from operations minus purchases of property and equipment and development costs. We believe that Free Cash Flow is a meaningful indicator of liquidity that provides information to our management and investors about the amount of cash generated from operations, after purchases of property and equipment that can be used for investment in our business and for acquisitions as well as to strengthen our balance sheet. Free Cash Flow has limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of other GAAP financial measures, such as net cash provided by operating activities. Free Cash Flow does not reflect our ability to meet future contractual commitments and may be calculated differently by other companies in our industry, limiting its usefulness as a comparative measure. For a reconciliation of Free Cash Flow to net cash provided by operating activities, the most directly comparable GAAP measure, see “—Comparison of non-GAAP financial measures.”

•

Adjusted ROCE. We use Adjusted ROCE (a non-GAAP measure) to evaluate the profitability of the Company’s capital employed in its business operations compared with that of its peers. We define Adjusted ROCE as net income plus interest expense, net, income tax expense and amortization expense for intangible assets, which we refer to as EBITA (a non-GAAP measure), divided by total assets less goodwill, other intangibles and total current liabilities. We believe Adjusted ROCE is a good indicator of long-term company and management performance as it relates to capital efficiency. For a reconciliation of EBITA and Adjusted ROCE to net income, the most directly comparable GAAP measure, see “—Comparison of non-GAAP financial measures.”

Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, EBITA and Adjusted ROCE are non-GAAP financial measures and should not be considered alternatives to, or more meaningful than, net income, net income as a percentage of revenue, net cash provided by operating activities, net income as a percentage of total assets or any other measure presented in accordance with GAAP. Our computation of Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, EBITA and Adjusted ROCE may differ from computations of similarly titled measures of other companies. For a reconciliation of these non-GAAP measures to the most directly comparable GAAP measures, see “—Comparison of non-GAAP financial measures.”

Factors affecting the comparability of our results of operations

The historical financial condition and results of operations of our predecessor for the periods presented may not be comparable, either from period to period or for HMH Inc. going forward, for the following reasons:

•

Corporate Reorganization. The historical consolidated financial statements included elsewhere in this prospectus are based on the financial statements of our accounting predecessor, HMH B.V. As a result, the historical consolidated financial data may not give you an accurate indication of what our actual results would have been if the corporate reorganization had been completed at the beginning of the periods presented or of what our future results of operations are likely to be. After giving effect to the corporate reorganization, HMH B.V. will be treated as a flow-through entity for U.S. federal income tax purposes and, as such, will generally not be subject to U.S. federal income tax at the entity level. The corporate reorganization

will be accounted for as a reorganization of entities under common control and, as a result, our consolidated financial statements will recognize the assets and liabilities received in the corporate reorganization at their historical carrying amounts, as reflected in the historical consolidated financial statements of HMH B.V. In addition, in connection with the corporate reorganization and this offering, we will enter into the Tax Receivable Agreement pursuant to which we will be required to pay the Principal Stockholders 85% of the net cash savings, if any, that we are deemed to realize as a result of our utilization of certain tax benefits described under “Certain relationships and related party transactions—Tax Receivable Agreement.” Finally, the corporate reorganization that will be completed in connection with the closing of this offering provides a mechanism by which the B.V. Non-Voting Shares will be allocated among the Principal Stockholders. As a result, the satisfaction of all conditions relating to the vesting of certain phantom awards in HMH B.V. held by our management and certain employees and non-employees will be probable. Accordingly, we will recognize a charge for stock compensation expense of $ related to the estimated fair value of the phantom awards at the time of grant, all of which will be non-cash. Based on an assumed initial offering price of $ per share (which is the midpoint of the price range set forth on the cover page of this prospectus), over the next year as the vesting conditions of the unvested phantom awards are satisfied, we will recognize additional non-cash charges for stock compensation expense of $ million.

•

IPO-Related Compensation Expenses. We expect to incur a one-time share-based compensation expense of $ million, based on an assumed initial offering price of $ per share (which is the midpoint of the price range set forth on the cover page of this prospectus), as a result of the successful completion of this offering. Certain of our employees and non-employees were granted Founders’ Awards, 2022 LTI Awards, 2023 LTI Awards and 2024 LTI Awards (each as defined herein and collectively, the “LTI Awards”), each of which are denominated in cash and, if the event triggering payment is an IPO (as defined in the award agreements), will settle in shares of our Class A common stock. The liability and associated compensation expense for these awards will not be recognized until an IPO is consummated. No share-based compensation expenses were recognized prior to the IPO because an IPO was not considered probable, so such general and administrative expenses are not reflected in our predecessor’s historical financial statements included elsewhere in this prospectus. See “Executive compensation—Outstanding equity awards at fiscal year-end” for more information.

•

Inflation and Macroeconomic Conditions. Our operational performance is influenced by prevailing economic conditions, including macroeconomic conditions, the overall inflationary climate and business sentiment. During 2022, 2023 and 2024, we experienced significant inflation in costs related to our products and services as a result of global inflationary trends. Ongoing inflationary pressures have resulted in, and may continue to result in, additional increases to the costs of goods, services, labor and personnel, which in turn could cause our capital expenditures and operating costs to rise, as well as a scarcity of certain products and raw materials, including steel. Like others in our industry, in 2022, 2023 and 2024, we faced, and continue to face, considerable inflation in the cost of raw materials and personnel. Sustained levels of high inflation caused the U.S. Federal Reserve to raise its target range for the federal funds rate multiple times in 2022 and 2023, but the U.S. Federal Reserve cut rates multiple times between September and December of 2024, resulting in a total aggregate increase of 425 basis points. The U.S. Federal Reserve’s target rate is currently between 4.25% and 4.50%. Future rate hikes from the U.S. Federal Reserve (or its equivalent in other nations) or other efforts to curb inflationary pressure on the costs of goods and services could have the effect of raising the cost of capital and depressing economic growth. As a result of the persistent economic and geopolitical uncertainty in many markets around the world, we have also experienced, and may in the future experience, fluctuations in foreign currency exchange rates, supply chain disruptions, lack of liquidity in the capital markets or an increase in interest rates, all of which may negatively affect us or the parties with whom we do business. Additionally, our floating rate indebtedness may subject us to increased borrowing costs.

100

•

Public Company Expenses. We expect to incur additional selling, general and administrative expenses as a result of becoming a publicly traded company. These costs include expenses associated with our annual and quarterly reporting, tax return preparation expenses, Sarbanes-Oxley Act compliance expenses, audit fees, legal fees, director and officer insurance, director compensation, national stock exchange fees, investor relations expenses and registrar and transfer agent fees. These additional selling, general and administrative expenses are not reflected in our predecessor’s historical financial statements included elsewhere in this prospectus.

•

Income Taxes. HMH Inc. is subject to U.S. federal and state income taxes as a corporation. HMH B.V. is treated as a flow-through entity for U.S. federal income tax purposes, and as such, is generally not subject to U.S. federal income tax at the entity level. Rather, the tax liability with respect to its taxable income will be passed through to the shareholders of HMH B.V., including HMH Inc., following the corporate reorganization. Accordingly, the financial data attributable to HMH B.V. contains no U.S. federal income tax expense or income tax expense in any state or locality (other than margin tax in the State of Texas). We estimate that HMH Inc. would have been subject to U.S. federal, state and local taxes at a blended statutory rate of % of 2023 pre-tax earnings and would be subject to a blended statutory rate of % of 2024 pre-tax earnings. Based on blended statutory rates of % and % for 2023 and 2024, respectively, HMH Inc. would have incurred pro forma income tax expense for the years ended December 31, 2023 and 2024 of $ million and $ million, respectively.

We have historically reported two operating segments: Equipment and System Solutions (“ESS”), which consists of the legacy MHWirth drilling equipment business, and Pressure Control Systems (“PCS”), which consists of the legacy Subsea Drilling Systems pressure control business. ESS is a supplier of drilling solutions and complete topside drilling packages and services to both onshore and offshore oil and gas producers and drilling contractors, which includes hoisting and rotating systems, drilling (mud) circulating systems, condition-based maintenance and other services. PCS is a supplier of integrated drilling products and services, and the key product offerings consist of BOPs and BOP control systems, drilling risers, wellhead connectors, technical and operational rig support that includes a 24/7 support center, CSAs and long-term service agreements.

The following table sets forth, for the periods indicated, disaggregated revenue by segment:



	Three months ended March 31,
(in thousands)	2025		2024

Revenue
Product revenue - ESS	$	36,111	$	21,579
Service revenue - ESS		41,398		50,595
Spare parts revenue - ESS		30,032		26,253

Total revenue - ESS	$	107,541	$	98,427
Product revenue - PCS	$	18,637	$	19,227
Service revenue - PCS		42,110		42,376
Spare parts revenue - PCS		30,142		33,836

Total revenue - PCS	$	90,889	$	95,439

Total revenue	$	198,430	$	193,866

During 2025, the Company continues to go through organizational changes and as a result of these changes, we anticipate discontinuing segment reporting based on ESS and PCS and the Chief Operating Decision Maker (“CODM”), who is our Chief Executive Officer, will begin assessing performance and making resource allocation decisions based on the breakdown between (i) sales of projects and products, (ii) aftermarket services and (iii) sales of spare parts. Equipment in our sales of projects and products generally falls under two broad categories: (i) pressure control systems (previously reported under the PCS segment), including BOPs, BOP control systems and drilling risers, and (ii) topside equipment (previously reported under the ESS segment), which is comprised of hoisting and rotating systems and drilling (mud) circulating systems. Aftermarket services includes services on installed equipment and integrated digital solutions. Our aftermarket services facilitate customers maintaining and improving the lifespan, safety and efficiency of their existing drilling rig fleets. Spare parts includes replacement parts for installed equipment used in oil and gas drilling operations. During the three months ended March 31, 2025, we derived 42.1% of our revenue from aftermarket services, 30.3% of our revenue from sales of spare parts and 27.6% of our revenue from sales of projects and products. Once the change is complete, prior period comparable results for segmented information will be recast to reflect the change in reportable segments. This segment reporting change will have no impact on our consolidated results.

Revenue. Revenue increased by $4.6 million, or 2.4%, to $198.4 million in the three months ended March 31, 2025 from $193.9 million in the three months ended March 31, 2024. The overall increase in revenue was driven by an increase in product revenue of $13.9 million and an increase in spare parts revenue of $0.1 million, partially offset by a decrease in service revenue of $9.5 million.

Service revenue decreased by $9.5 million, or 10.2%. This was due to decreased volume from overhaul and repair activity. As a result, service revenue accounted for 42.1% of our total revenue in the three months ended March 31, 2025, which was a decrease from 48.0% in the three months ended March 31, 2024.

Spare parts revenue increased by $0.1 million, or 0.1%. This was due to improved convertibility of existing backlog. As a result, spare parts revenue accounted for 30.3% of our total revenue in the three months ended March 31, 2025, which was a decrease from 31.0% in the three months ended March 31, 2024.

Product revenue increased by $13.9 million, or 34.2%. The higher product revenue across our business was mainly due to higher progress on ongoing projects. As a result, product revenue accounted for 27.6% of our total revenue in the three months ended March 31, 2025, which was an increase from 21.0% in the three months ended March 31, 2024.

Cost of sales. Cost of sales increased by $9.2 million, or 6.9%, to $141.9 million in the three months ended March 31, 2025, up from $132.7 million in the three months ended March 31, 2024. Cost of sales as a percentage of revenue increased to 71.5% in the three months ended March 31, 2025 as compared to 68.4% in the three months ended March 31, 2024. The increase in cost of sales and cost of sales as a percentage of revenue was primarily due to mix as we had a higher proportion of product revenue in the quarter as well as lower utilization of our service and spares facilities. This was partially offset by completion of unfavorable product contracts in 2024 that did not repeat in 2025, leading to cost reductions.

Cost of services sold increased by $1.3 million, or 2.3%, to $57.1 million in the three months ended March 31, 2025, up from $55.8 million in the three months ended March 31, 2024. The increase in cost of services sold was mainly due to mix and lower utilization of service shops in the period. Cost of services sold as a percentage of service revenue increased to 68.4% in the three months ended March 31, 2025 as compared to 60.0% in the three months ended March 31, 2024, mainly due to the change in revenue mix within service sales.

Cost of goods sold - spare parts increased by $5.4 million, or 16.6%, to $38.1 million in the three months ended March 31, 2025, up from $32.7 million in the three months ended March 31, 2024. The increase in cost of goods sold - spare parts was due to lower utilization of spare parts facilities in the period, leading to cost increases. Cost of goods sold - spare parts as a percentage of spare parts revenue increased to 63.3% in the three months ended March 31, 2025 as compared to 54.4% in the three months ended March 31, 2024, mainly due to the above mentioned facility utilization in the period.

Cost of goods sold - products increased by $2.5 million, or 5.6%, to $46.7 million in the three months ended March 31, 2025, up from $44.2 million in the three months ended March 31, 2024. The increase in cost of goods sold - products was in line with the increase in products revenue. Cost of goods sold - products as a percentage of product and related party revenue decreased to 85.3% in the three months ended March 31, 2025 as compared to 108.4% in the three months ended March 31, 2024 due to product and project contracts with lower margins that did not repeat in 2025.

Selling, general and administrative expenses. For the three months ended March 31, 2025, selling, general and administrative expenses decreased by $1.7 million, or 4.4%, to $36.2 million from $37.9 million in the three months ended March 31, 2024. This decrease was attributable mainly to continued cost optimization efforts.

Research and development expenses. For the three months ended March 31, 2025, research and development expenses decreased by $0.2 million, or 19.2%, to $1.0 million from $1.3 million in the three months ended March 31, 2024. This decrease was attributable mainly to timing of our research and development efforts.

103

Restructuring expenses. For the three months ended March 31, 2025, restructuring expenses increased to $3.3 million from zero in restructuring expenses in the three months ended March 31, 2024. This increase was attributable to restructuring expenses for lease exits and cost reduction programs.

Foreign currency gain (loss), net. For the three months ended March 31, 2025, the change in foreign currency gain (loss) was favorable by $5.6 million, or 347.4%, to an income of $4.0 million from an expense of $1.6 million in the three months ended March 31, 2024. This favorable variance was attributable mainly to currency exchange rate movements of the U.S. dollar as compared to other currencies in which we transact.

Interest expense, net. For the three months ended March 31, 2025, interest expense, net increased by $1.1 million, or 13.7%, to $9.2 million from $8.1 million in the three months ended March 31, 2024. This increase was attributable mainly to interest rate and balance variability on our revolving credit facility in the three months ended March 31, 2025 relative to the three months ended March 31, 2024.

Income tax expense. For the three months ended March 31, 2025, income tax expense increased by $1.1 million, or 27.5%, to an income tax expense of $5.3 million from an income tax expense of $4.1 million in the three months ended March 31, 2024. This increase was attributable mainly to an increase in profit during the three months ended March 31, 2025, coupled with a change in our geographic mix of revenues.

The following table sets forth, for the periods indicated, disaggregated revenue by segment:



	Year ended December 31,
(in thousands)	2024		2023

Total revenue - PCS	$	400,174	$	404,611

Total revenue	$	843,363	$	785,446

Revenue. Revenue increased by $57.9 million, or 7.4%, to $843.4 million in 2024 from $785.4 million in 2023. The overall increase in revenue was driven by an increase in service revenue of $37.5 million and an increase in product revenue of $40.8 million, partially offset by a decrease in spare parts revenue of $20.4 million.

Product revenue increased by $40.8 million, or 21.6%. The higher product revenue across our business was mainly due to volume increases driven by market demand. As a result, product revenue accounted for 27.2% of our total revenue in 2024, which was an increase from 24.0% in 2023.

Service revenue increased by $37.5 million, or 11.4%. This was due to increased volume from overhaul and repair activity and digital technology upgrades. As a result, service revenue accounted for 43.4% of our total revenue in 2024, which was an increase from 41.8% in 2023.

Spare parts revenue decreased by $20.4 million, or 7.6%. This was due to a reduction in volume in the second half of 2024 driven by flat rig activity and restrained spending by customers. As a result, spare parts revenue accounted for 29.4% of our total revenue in 2024, which was a decrease from 34.2% in 2023.

Cost of sales. Cost of sales decreased by $3.9 million, or 0.7%, to $571.2 million in 2024, down from $575.1 million in 2023. Cost of sales as a percentage of revenue decreased to 67.7% in 2024 as compared to 73.2% in 2023. The decrease in cost of sales and cost of sales as a percentage of revenue was primarily due to improvement in indirect manufacturing expenses in 2024 and completion of unfavorable product contracts in 2023 that did not repeat in 2024 leading to cost reductions, offset by the increases in cost of sales associated with revenue growth.

Cost of goods sold - products decreased by $17.6 million, or 7.9%, to $205.2 million in 2024, down from $222.7 million in 2023. The decrease in cost of goods sold - products was due to sales of product and project contracts with lower margins in 2023 that did not repeat in 2024 and improvement in indirect manufacturing expenses. Cost of goods sold - products as a percentage of product and related party revenue decreased to 89.5% in 2024 as compared to 118.3% in 2023 due to product and project contracts with lower margins that did not repeat in 2024.

Cost of services sold increased by $19.8 million, or 9.7%, to $223.4 million in 2024, up from $203.6 million in 2023. The increase in cost of services sold was mainly in line with the increase in service revenue for the year ended December 31, 2024. Cost of services sold as a percentage of service revenue decreased to 61.0% in 2024 as compared to 62.0% in 2023, mainly due to the change in revenue mix within service sales.

105

Cost of goods sold - spare parts decreased by $6.1 million, or 4.1%, to $142.6 million in 2024, down from $148.7 million in 2023. The decrease in cost of goods sold - spare parts was in line with the decrease in spare parts revenue for the year ended December 31, 2024. Cost of goods sold - spare parts as a percentage of spare parts revenue increased to 57.5% in 2024 as compared to 55.4% in 2023, mainly due to the change in revenue mix of spare parts sales.

Selling, general and administrative expenses. For 2024, selling, general and administrative expenses increased by $19.4 million, or 15.2%, to $146.8 million from $127.4 million in 2023. This increase was attributable mainly to public company readiness expenses incurred in 2024.

Research and development expenses. Research and development expenses increased by $4.0 million, or 132.4%, to $7.0 million from $3.0 million in 2023. This increase was attributable mainly to continued development work on in-process R&D efforts for our pressure control suite of products.

Other operating expenses (income), net. For 2024, other operating expenses (income), net decreased by $2.2 million, or 115.6%, to $0.3 million of other operating income, net from $1.9 million of other operating expenses, net in 2023. This decrease was attributable mainly to restructuring expenses that occurred in 2023 that did not repeat in 2024.

Foreign currency gain (loss), net. For 2024, the change in foreign currency gain (loss) was unfavorable by $6.1 million, or 764.9%, to an expense of $5.3 million in 2024 from an income of $0.8 million in 2023. This unfavorable variance was attributable mainly to currency exchange rate movements of the U.S. dollar to other currencies in which we transact.

Interest expense, net. For 2024, interest expense, net decreased by $9.0 million, or 19.5%, to $37.3 million from $46.3 million in 2023. This decrease was attributable mainly to our bond refinancing in November 2023 in which we successfully placed a new $200.0 million senior secured bond at a reduced cost of capital.

Income tax expense. For 2024, income tax expense increased by $9.2 million, or 59.8%, to an income tax expense of $24.5 million from an income tax expense of $15.4 million in 2023. This increase was attributable mainly to an increase in profit during 2024 coupled with a change in our geographic mix of revenues.

Comparison of non-GAAP financial measures

We have performed a detailed analysis of the non-GAAP measures that are relevant to our business and its operations and determined that the appropriate units of measure to analyze our performance are Adjusted EBITDA (net income before interest expense, net, income tax expense, depreciation and amortization and certain non-recurring items that we do not consider to be indicative of our ongoing operating performance such as, but not limited to, IT system implementation, restructuring expenses and foreign currency transaction (gain) loss), Adjusted EBITDA Margin (Adjusted EBITDA divided by revenue), Free Cash Flow (cash flow from operations minus purchases of property and equipment and development costs) and Adjusted ROCE (net income plus interest expense, net, income tax expense and amortization expense for intangible assets, or EBITA, divided by total assets less goodwill, other intangibles and total current liabilities). We believe that the adjustments and exclusions in each of these non-GAAP financial measures enable us to evaluate more effectively our operations period over period and to identify operating trends that could otherwise be masked by unadjusted or excluded items. It is our determination that Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow and Adjusted ROCE are more relevant measures of how we review our ability to meet commitments and pursue capital projects.

Adjusted ROCE for the three months ended March 31, 2025 was 3.5%, a decrease of 5.0% from 8.5% for the three months ended March 31, 2024. The primary reason for the decrease was a decrease in net income as a result of factors discussed above, coupled with lower intangible asset amortization and lower total current liabilities for the three months ended March 31, 2025 as compared to the three months ended March 31, 2024.

Adjusted ROCE for the year ended December 31, 2024 was 19.7%, an increase of 4.4% from 15.3% for the year ended December 31, 2023. The primary reason for the increase was an increase in net income as a result of factors discussed above, coupled with a decrease in total current liabilities for 2024 as compared to 2023.

Costs of conducting our business

The principal costs of products and services involved in operating our business are manufacturing costs, raw materials and direct labor costs. Our fixed costs are relatively low and a large portion of the costs described below are only incurred as we perform jobs for our customers.

Manufacturing costs. As an OEM, our manufacturing costs include machine time, lease expense related to our manufacturing facilities, freight and other variable manufacturing costs. Certain of these costs are constant, such as lease expense, while others are variable depending on the type and quantity of customer orders.

108

Raw materials. Our manufacturing of products relies on various raw materials and component parts, specifically various grades of steel and other raw metals.

Direct labor costs. Payroll and benefit expenses directly related to the delivery of our products and services are included in our cost of sales.

Liquidity and capital resources

Our financial objectives include the maintenance of sufficient liquidity, adequate financial resources and financial flexibility to fund our business. Our primary sources of liquidity are, and after the completion of this offering are expected to continue to be, our existing cash on hand, cash generated from operations, borrowings under the Revolver, borrowings under the Senior Secured Bonds, under which we can increase borrowings by up to $75.0 million and can also enter into separate bridge financing facilities, and proceeds from this offering. As of March 31, 2025, December 31, 2024 and December 31, 2023, our cash and cash equivalents were $47.0 million, $48.9 million and $62.5 million, respectively. As of March 31, 2025, December 31, 2024 and December 31, 2023, our availability under the Revolver was $50.0 million, $35.6 million and $28.9 million, respectively. As of March 31, 2025, December 31, 2024 and December 31, 2023, our total indebtedness was $332.1 million, $343.1 million and $338.2 million, respectively.

Our total capital expenditures are estimated to range between $15 million and $20 million for 2025. Our total capital expenditures, including development costs, were $2.4 million and $18.3 million for the three months ended March 31, 2025 and the year ended December 31, 2024, respectively, of which $2.3 million and $16.1 million, respectively, were used for the purchase or manufacture of equipment to directly support customer-related activities in addition to purchases of property, plant and equipment, inclusive of software costs. The actual amount of capital expenditures for the purchase and manufacture of equipment may fluctuate based on market conditions. We continue to focus on preserving and protecting our strong balance sheet, optimizing utilization of our existing assets and, where practical, limiting new capital expenditures.

We have certain obligations related to debt maturities, finance leases and operating leases. As of March 31, 2025, we had $7.9 million of operating lease obligations during the remainder of 2025 and, for periods after 2025, we had an additional $74.5 million of operating lease obligations. As of March 31, 2025, the incremental borrowing rate on our lease obligations ranged from 3.0% to 11.5%.

In addition, as of March 31, 2025, we had no debt maturities during the remainder of 2025, and $300.0 million aggregate principal amount of debt maturities during 2026 comprised of $200.0 million of Senior Secured Bonds maturities and $100.0 million of Shareholder Loans maturities. Any additional outstanding balances that we may draw under the Revolver would become due and payable in May 2026. Interest on the Senior Secured Bonds accrued at a fixed rate of 10.875% per annum as of March 31, 2025 (which was increased from 9.875% per annum beginning on August 17, 2024 until the Senior Secured Bonds are listed on the Oslo Stock Exchange). Our effective interest rate on the Revolver for the year ended December 31, 2024 was the compounded reference rate plus 3.75%. In November 2023, we paid off all outstanding borrowings under our $70.0 million term loan facility, which bore interest at a rate of Secured Overnight Financing Rate (“SOFR”) plus 4.01% for tranche A and SOFR plus 5.01% for tranche B. In addition, in November 2023, we refinanced our $150.0 million Senior Secured Floating Rate Bond and replaced it with our $200.0 million Senior Secured Bonds. See “Note 10—Debt” to our audited consolidated financial statements for additional information.

We believe that our existing cash on hand, cash generated from operations and available capacity under the Revolver and the Senior Secured Bonds will be sufficient to meet our liquidity needs in the short term and long term. Our ability to satisfy our liquidity requirements depends on our future operating performance, which is affected by prevailing economic conditions, market conditions in the oil and natural gas industry, availability and cost of raw materials and other factors, many of which are beyond our control.

Increase (decrease) in cash and cash equivalents	$	(1,928	)	$	(13,290	)	$	(13,612	)	$	15,188

Operating activities

Net cash provided by operating activities for the three months ended March 31, 2025 increased by $1.7 million compared to the three months ended March 31, 2024, primarily due to a $4.8 million favorable change in non-cash expenses, partially offset by a decrease in net income of $2.6 million and a $0.5 million unfavorable change in operating assets and liabilities.

Net income was unfavorable by $2.6 million as we generated net income of $5.9 million for the three months ended March 31, 2025 as compared to net income of $8.5 million for the three months ended March 31, 2024. The reasons for the decrease in net income are set forth under “—Results of operations.”

The change in operating assets and liabilities for the three months ended March 31, 2025 resulted in a $0.5 million decrease in cash as compared to the change in operating assets and liabilities for the three months ended March 31, 2024. The decrease in cash resulting from the changes in assets and liabilities was primarily due to decreases in contract assets and accounts payable and accounts payable—related party, offset by increases in accrued expenses and inventories, net.

The unfavorable cash variance in contract assets resulted from the fulfillment of performance obligations relative to the timing of milestone invoicing. The unfavorable cash variance in accounts payable and accounts payable—related party resulted from increased vendor payments made during the three months ended March 31, 2025.

The favorable cash variance resulting from inventories, net was due to a slower build of inventory in the three months ended March 31, 2025 relative to the increase in the three months ended March 31, 2024. The favorable cash variance resulting from accrued expenses was due to the timing of expense recognition relative to vendor invoices.

Non-cash expenses were favorable by $4.8 million for the three months ended March 31, 2025 compared to the three months ended March 31, 2024. The favorable variance in non-cash expenses was driven by increases in depreciation and amortization expense, restructuring expenses and deferred income tax expense.

Net cash provided by operating activities in 2024 increased by $9.3 million compared to 2023, primarily due to increases resulting from a positive change in net income of $34.6 million, a $28.8 million unfavorable change in operating assets and liabilities and a $3.5 million favorable change in non-cash expenses.

Net income was favorable by $34.6 million as we generated net income of $52.0 million in 2024 as compared to net income of $17.4 million in 2023. The reasons for the increase in net income are set forth under “—Results of operations.”

The change in operating assets and liabilities during 2024 resulted in a $28.8 million decrease in cash as compared to the change in operating assets and liabilities during 2023. The decrease in cash resulting from the changes in assets and liabilities was primarily due to a decrease in contract liabilities, offset by an increase in inventories.

110

The unfavorable cash variance in contract liabilities resulted from the fulfillment of performance obligations relative to the timing of milestone invoicing. This was offset by a favorable cash variance resulting from inventories, net due to a slower build of inventory in 2024 relative to the increase in 2023. This was due to a 2023 strategic build of inventory in anticipation of 2024 and beyond demand and deliveries.

Non-cash expenses were favorable by $3.5 million in 2024 compared to 2023. The favorable variance in non-cash expenses was driven by higher depreciation and amortization expense and deferred income tax expense in 2024.

Investing activities

Net cash used in investing activities decreased by $2.3 million for the three months ended March 31, 2025 as compared to the three months ended March 31, 2024. The decrease in net cash used in investing activities was principally the result of a $1.8 million decrease in purchase of property, plant and equipment.

Net cash used in investing activities increased by $13.9 million in 2024 as compared to 2023. The increase in net cash used in investing activities was principally the result of a $19.6 million increase in net cash paid for the Drillform business combination in 2024, offset by a $6.3 million decrease in capital expenditures in 2024.

Financing activities

Net cash used in financing activities decreased by $5.5 million for the three months ended March 31, 2025 as compared to three months ended March 31, 2024 from a net use of cash of $20.5 million for the three months ended March 31, 2024 to $15.0 million for the three months ended March 31, 2025. The results for both periods were due to the pay down of outstanding credit facilities balances.

Net cash provided by financing activities decreased by $22.0 million in 2024 as compared to 2023 from a net source of cash of $14.7 million in 2023 to a net use of cash of $7.3 million in 2024. The unfavorable variance was primarily due to the net payment of debt in 2024 versus a net cash borrowing in 2023, partially offset by decreased borrowing costs paid in 2024 versus the higher borrowing costs in 2023 due to the refinancing of our debt.

Debt agreements

Revolver

On November 20, 2023, HMH B.V., DNB Bank ASA, as agent, certain financial institutions party thereto as lenders (the “Revolver Lenders”) and DNB Carnegie, a part of DNB Bank ASA, and Nordea Bank Abp, filial i Norge, as mandated lead arrangers and bookrunners, entered into a senior facility agreement (as amended, the “Revolver”) pursuant to which the Revolver Lenders provide revolving credit financing to HMH B.V. in an aggregate principal amount of up to $50.0 million. The scheduled maturity date of the Revolver is May 16, 2026.

Borrowings under the Revolver bear interest at the compounded reference rate, which is the applicable SOFR plus the applicable credit spread adjustment, plus a margin of 3.50% to 4.25% based on HMH B.V.’s most recent leverage ratio. In addition to paying interest on outstanding principal under the Revolver, HMH B.V. is required to pay a quarterly commitment fee equal to 40% of the applicable margin on the unused available commitments.

The Revolver is secured by liens on substantially all of HMH B.V.’s assets, including the equity of its material subsidiaries, and guarantees, either directly or indirectly, from its material subsidiaries. The security of the Revolver is subject to the Intercreditor Agreement (as defined herein) with the trustee under the Senior Secured Bonds. The Revolver includes certain restrictive covenants that may limit our ability to, among other things, incur additional indebtedness, guarantee obligations, incur liens, make investments, loans or capital expenditures, sell or dispose of assets, enter into mergers or consolidations, enter into transactions with affiliates or make or declare dividends. The Revolver also requires HMH B.V. to maintain at all times a minimum

111

liquidity of not less than $30.0 million, a gearing ratio of Consolidated Net Total Borrowings to Consolidated Total Equity (each as defined in the Revolver) not to exceed 1.00 to 1.00 and an interest cover ratio of Adjusted EBITDA to Net Interest Expenses (each as defined in the Revolver) of not less than 2.50 to 1.00. The Revolver contains customary representations and warranties, affirmative covenants and events of default. If an event of default exists under the Revolver, the Revolver Lenders will be able to accelerate the maturity of the Revolver and exercise other rights and remedies. If an event of default exists under the Senior Secured Bonds, a cross-default will be triggered under the Revolver, and the Revolver Lenders will be able to accelerate the maturity of the Revolver and exercise other rights and remedies. Subject to certain notice requirements and certain partial prepayment amount restrictions, HMH B.V. may voluntarily prepay outstanding loans under the Revolver in whole or in part without premium or penalty. Following a Change of Control (as defined in the Revolver), HMH B.V. can be required to prepay the loans in whole if the parties do not reach an agreement to continue the loan.

On March 10, 2025, DNB Bank ASA agreed as agent under the Revolver to amend certain terms of the Revolver to permit implementation of the corporate reorganization and the listing of our Class A common stock on Nasdaq, and the documentation formally implementing the same became effective as of March 11, 2025.

Intercreditor Agreement

On November 22, 2023, the facility agent under the Revolver and the trustee under the Senior Secured Bonds entered into a pari passu intercreditor agreement (the “Intercreditor Agreement”) (subject to the super senior ranking of HMH B.V.’s obligations under the Revolver and the hedging liabilities, in each case, with respect to the applications of proceeds thereunder) governing (i) the relative priorities of their respective security interests in the assets securing the Revolver, the Senior Secured Bonds and certain future secured indebtedness and (ii) certain other matters relating to the administration of their respective security interests, including the occurrence of an insolvency event.

Senior Secured Bonds

On or around November 15, 2023, HMH B.V. issued $200.0 million aggregate principal amount of its senior secured bonds (the “Senior Secured Bonds”), which mature on November 16, 2026. Interest on the Senior Secured Bonds accrued at a fixed rate of 10.875% per annum as of March 31, 2025 (which was increased from 9.875% per annum beginning on August 17, 2024 as a result of our failure to list the Senior Secured Bonds on the Oslo Stock Exchange by August 16, 2024). Upon the listing of the Senior Secured Bonds on the Oslo Stock Exchange, the fixed interest rate will revert to 9.875% per annum. The Senior Secured Bonds are secured by liens on substantially all of HMH B.V.’s assets, including the equity of its material subsidiaries, and guarantees, either directly or indirectly, from its material subsidiaries. The security of the Senior Secured Bonds is subject to the Intercreditor Agreement with the facility agent under the Revolver. The agreement governing the Senior Secured Bonds includes customary representations and warranties, affirmative covenants and certain restrictive covenants that may limit our ability to, among other things, incur additional indebtedness, guarantee obligations, incur liens, make investments, loans or capital expenditures, sell or dispose of assets, enter into mergers or consolidations, enter into transactions with affiliates or make or declare dividends. The Senior Secured Bonds also require HMH B.V. to maintain at all times a minimum liquidity of not less than $30.0 million, a gearing ratio of Consolidated Net Total Borrowings to Consolidated Total Equity (each as defined in the agreement governing the Senior Secured Bonds) not to exceed 1.00 to 1.00 and an interest cover ratio of Adjusted EBITDA to Net Interest Expenses (each as defined in the agreement governing the Senior Secured Bonds) of not less than 2.50 to 1.00. Subject to compliance with certain conditions, HMH B.V. is permitted to increase its borrowings under the Senior Secured Bonds by up to $75.0 million, and HMH B.V. is also permitted to enter into certain bridge financing facilities with the lender(s) party thereto. HMH B.V. intends to list the Senior Secured Bonds on the Oslo Stock Exchange during the first half of 2025. The agreement governing the Senior Secured Bonds contains customary events of default. If an event of default exists under the Senior Secured Bonds, the lenders will be able to accelerate the maturity of the Senior Secured Bonds and exercise other rights and remedies. If an event of default exists under the Revolver, a cross-default will be triggered

112

under the Senior Secured Bonds, and the bondholders thereunder will be able to accelerate the maturity of the Senior Secured Bonds and exercise other rights and remedies.

The Senior Secured Bonds are redeemable, at our option, (i) prior to May 16, 2025, at a price equal to the make-whole amount and (ii) beginning on May 16, 2025, at a premium of 104.938%. The redemption premium then declines in steps until May 16, 2026, at which time we may redeem the bonds at a premium of 100.500%. The redemption premium then falls away at the maturity date, at which time we may redeem the bonds at par value.

Following a Change of Control or a Share De-Listing Event (each as defined in the agreement governing the Senior Secured Bonds), HMH B.V. can be required to prepay the Senior Secured Bonds at 101% of the nominal amount of the bonds being repaid.

Following a material asset sale, HMH B.V. can be required to prepay the Senior Secured Bonds at 100% of the nominal amount of the bonds being repaid, up to 50% of the gross proceeds of the material asset sale.

On December 11, 2024, the holders of the Senior Secured Bonds agreed, in exchange for a one-time consent fee, to amend certain terms of the Senior Secured Bonds to permit implementation of the corporate reorganization and the listing of our Class A common stock on Nasdaq, and the documentation formally implementing the same became effective as of February 12, 2025.

Shareholder Loans

On October 1, 2021, HMH B.V. entered into a loan agreement with Baker Hughes Holdings LLC and Akastor AS (as amended, the “Shareholder Loan Agreement”) to finance its operating and finance activities. Baker Hughes Holdings LLC provided an $80.0 million term loan under the Shareholder Loan Agreement (the “Baker Hughes Shareholder Loan”), and Akastor AS provided a $20.0 million term loan under the Shareholder Loan Agreement (the “Akastor Shareholder Loan” and, together with the Baker Hughes Shareholder Loan, the “Shareholder Loans”). The Shareholder Loans mature on the earliest to occur of October 1, 2026 or a liquidation event (as defined in the Shareholder Loan Agreement) such as the consummation of this offering. As of March 31, 2025, the total amount of principal and accrued and unpaid interest outstanding under the Shareholder Loans was $134.6 million, which included $105.9 million outstanding under the Baker Hughes Shareholder Loan and $28.7 million outstanding under the Akastor Shareholder Loan. HMH B.V. also agreed to pay Baker Hughes and Akastor for certain deferred tax assets related to the contributed businesses in the amounts of approximately $0.3 million and $2.2 million, respectively, with such payment made by way of an increase to the Shareholder Loans. Such additional amounts relating to deferred tax assets are reflected in the Shareholder Loans’ balances as of March 31, 2025. The Shareholder Loans bear interest at a rate of 8.0% per annum. The Shareholder Loans are unsecured. The Shareholder Loan Agreement includes certain restrictive covenants that may limit our ability to, among other things, incur additional indebtedness or make or declare dividends. The Shareholder Loan Agreement contains customary representations and warranties, affirmative covenants and events of default. If an event of default exists under the Shareholder Loan Agreement, the lenders will be able to accelerate the maturity of the Shareholder Loans and exercise other rights and remedies. Subject to certain notice requirements, HMH B.V. may voluntarily prepay outstanding loans under the Shareholder Loan Agreement in whole or in part without premium or penalty.

We intend to contribute a portion of the net proceeds from this offering to HMH B.V., and HMH B.V. intends to use $ million of the net proceeds received by it to repay all of the outstanding principal and accrued and unpaid interest under the Shareholder Loans, which totaled $134.6 million as of March 31, 2025. See “Use of proceeds.”

Credit Line in China

On August 22, 2023, HMH B.V. entered into a credit line agreement (the “2023 Credit Line in China”) with Bank of China Shanghai Pudong branch (the “Credit Line in China Lender”) pursuant to which the Credit Line in China Lender

113

provided a credit line in an aggregate principal amount of up to Chinese renminbi (RMB) 10.0 million. The 2023 Credit Line in China expired by its terms on July 26, 2024. The borrowing length for each withdrawal was one year. As of September 22, 2024, all borrowings under the 2023 Credit Line in China had matured and been repaid by HMH B.V.

On March 27, 2025, HMH B.V. entered into a credit line agreement (the “Credit Line in China”) with the Credit Line in China Lender pursuant to which the Credit Line in China Lender provided a credit line in an aggregate principal amount of up to Chinese renminbi (RMB) 10.0 million. The Credit Line in China has an effective period from March 27, 2025 to March 26, 2026. The borrowing length for each withdrawal is one year.

Borrowings under the Credit Line in China bear interest at the compounded reference rate, which is the applicable China Loan Prime Rate minus margin 0.4%. Interest is paid quarterly in the last month of each quarter. There is no quarterly commitment fee or guarantee requirement based on HMH B.V.’s financial status. As of March 31, 2025 and December 31, 2024, the aggregate principal amount outstanding under the Credit Line in China was zero.

The Credit Line in China is only to be used for HMH B.V.’s daily operations and cannot be used to purchase real estate, re-lend to other companies or make investments.

Contractual obligations

Our material contractual obligations as of March 31, 2025 consisted of the following:

•

total debt of $332.1 million, which included $200.0 million aggregate principal amount of the Senior Secured Bonds due in November 2026 that accrued interest at a fixed rate of 10.875% per annum as of March 31, 2025 (which was increased from 9.875% per annum beginning on August 17, 2024 until the Senior Secured Bonds are listed on the Oslo Stock Exchange), $80.0 million aggregate principal amount outstanding under the Baker Hughes Shareholder Loan that accrues interest at a rate of 8.0% per annum and $20.0 million aggregate principal amount outstanding under the Akastor Shareholder Loan that accrues interest at a rate of 8.0% per annum;

•

non-cancellable leases for our various facilities, which have future minimum payments of $10.2 million, $8.8 million, $7.0 million, $5.5 million and $3.5 million, as of December 31, 2025, 2026, 2027, 2028 and 2029, respectively;

•

purchase commitments of $81.4 million, which are due within 24 months, that primarily consist of commitments to purchase materials for the satisfaction of our contractual obligations; and

•

various bank guarantees totaling $49.3 million, such as advance payment guarantees, surety bonds, performance guarantees, bid bonds, customs and tax guarantees to guarantee the Company’s performance as it relates to contracts with customers, contract bidding, customs duties, tax appeals and obligations in various jurisdictions.

Tax Receivable Agreement

With respect to obligations we expect to incur under the Tax Receivable Agreement (except in cases where we elect to terminate the Tax Receivable Agreement early or the Tax Receivable Agreement is terminated early due to other circumstances, including our breach of a material obligation thereunder or certain mergers or other changes of control), payments are generally due within a specified period of time following the filing of our tax return for the taxable year with respect to which the payment obligation arises, and interest on such payments will accrue from the due date (without extensions) of such tax return. In certain cases, payments under the Tax Receivable Agreement may be accelerated and/or significantly exceed the actual benefits, if any, we realize in respect of the tax attributes subject to the Tax Receivable Agreement. We intend to account for any amounts

114

payable under the Tax Receivable Agreement in accordance with Accounting Standards Codification (“ASC”) Topic 450, Contingent Consideration. For further discussion regarding the potential acceleration of payments under the Tax Receivable Agreement and its potential impact, please read “Risk Factors—Risks related to this offering and our Class A common stock.” For additional information regarding the Tax Receivable Agreement, see “Certain relationships and related party transactions—Tax Receivable Agreement.”

Capital expenditures

In addition to our operating metrics and contractual obligations, we also focus on capital expenditures. Our two primary categories of capital expenditures are property and equipment and development costs. For the three months ended March 31, 2025, our capital expenditures related to property and equipment were $2.3 million, and our capital expenditures related to development costs were $0.1 million. For the years ended December 31, 2024 and 2023, our capital expenditures related to property and equipment were $16.1 million and $14.1 million, respectively. Expenditures for development costs were $2.2 million and $10.5 million for the years ended December 31, 2024 and 2023, respectively.

Implications of being an emerging growth company

We are an “emerging growth company,” as defined in the JOBS Act, and we may remain an emerging growth company for up to five years following the completion of this offering. For so long as we remain an emerging growth company, we are permitted and intend to rely on certain exemptions from various public company reporting requirements, including not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and any golden parachute payments not previously approved. In particular, in this prospectus, we have provided only two years of audited financial statements and have not included all of the executive compensation-related information that would be required if we were not an emerging growth company. Accordingly, the information contained herein may be different than the information you receive from other public companies in which you hold stock.

Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have elected to use this extended transition period for complying with certain new or revised accounting standards. As a result, our financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Critical accounting policies and estimates

The discussion and analysis of our financial condition and results of operations is derived from the review of our predecessor’s consolidated financial statements prepared in accordance with GAAP, which includes our interpretation of accounting guidance and application through accounting policies. The preparation of our predecessor’s financial statements requires the use of judgments and estimates. Our critical accounting estimates are described below to provide a better understanding of how we develop our assumptions and judgments about future events and related estimates and how they can impact our financial statements. A critical accounting estimate is one that requires our most difficult, subjective or complex judgments and assessments and is fundamental to our results of operations.

We base our estimates on historical experience and on various other assumptions we believe to be reasonable according to the current facts and circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We believe the following are the critical accounting estimates used in the preparation of our consolidated financial statements, as

115

well as the significant estimates and judgments affecting the application of these policies. This discussion and analysis should be read in conjunction with our consolidated financial statements and related notes thereto included elsewhere in this prospectus.

Our predecessor’s historical financial statements included elsewhere in this prospectus include the accounts of each wholly owned subsidiary of HMH B.V. All intercompany accounts and transactions have been eliminated in the financial statements.

Revenue recognition

Revenue from performance obligations satisfied over time, typically in project contracts and service contracts, is recognized according to progress. This requires estimates of the final total revenue, as well as measurement of progress achieved to date as a proportion of the total work to be performed. The estimated progress in long-term project and other manufacturing contracts is based on internal and external estimates of progress.

Revenue from project and other manufacturing contracts is recognized according to progress. The input method used to measure progress is determined by reference to the costs incurred to date relative to the total estimated contract cost. Because of the uniqueness of the project and the required engineering in the initial phases of construction contracts, we may defer recognition of revenue, in excess of costs, until the point that progress can be measured reliably, which is when a project is approximately 20% complete.

Variable consideration for liquidated damages is recognized as a reduction of the transaction price unless it is highly probable that it will not be incurred. Disputed amounts and claims are only recognized when negotiations have reached an advanced stage, customer acceptance is highly likely and the amounts can be measured reliably.

Income taxes

We operate through various subsidiaries in a number of countries throughout the world. Income taxes have been recorded based upon the income tax laws and rates of the countries in which we operate and earn income. Our annual income tax expense is based on taxable income, statutory income tax rates and tax planning opportunities available in the various jurisdictions in which we operate.

The financial statement effects of tax positions are recognized if the tax position is more likely than not to be realized. Recognized tax positions are measured as the largest amount of tax benefit that is greater than 50 percent likely of being realized. A valuation allowance is established for any portion of a deferred tax asset that management believes is not more likely than not to be realized. Valuation of deferred tax assets is dependent on management’s assessment of future recoverability of the deferred tax benefit. Expected recoverability may result from expected taxable income in the near future, planned transactions or planned tax optimizing measures. Economic conditions may change and lead to a different conclusion regarding recoverability, and such change may affect the results for each future reporting period.

Goodwill impairment

We perform impairment testing if any impairment indicators are identified. We first assess qualitative factors to determine whether it is more likely than not that the fair value of our reporting unit is less than its carrying value. If the qualitative assessment indicated that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, a quantitative test is required. These calculations require management to estimate future cash flows expected to arise from these reporting units and an appropriate discount rate to reflect the time value of the money. The discounted cash flow is based on management’s forecast of operating performance for each reporting unit. The two main assumptions used in measuring

116

goodwill impairment, which bear the risk of change and could impact our goodwill impairment analysis, include the cash flow from operations from each of our individual reporting units and the weighted average cost of capital. The starting point for each reporting unit’s cash flow from operations is the detailed annual plan or updated forecast. Cash flows beyond the specific operating plans were estimated using a terminal value calculation, which incorporated historical and forecasted financial cyclical trends for each reporting unit and considered long-term earnings growth rates in the oil and gas industry. The financial and credit market volatility directly impacts our fair value measurement through our weighted average cost of capital that we use to determine our discount rate. Key assumptions made by management also include assumptions for future market conditions, which require a high degree of judgment. If the carrying value of the reporting unit including goodwill exceeds its fair value, an impairment charge equal to the excess would be recognized up to a maximum amount of goodwill allocated to that reporting unit.

New accounting standards to be adopted

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 provide for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 is effective for us prospectively to all annual periods beginning after December 15, 2025. Early adoption is permitted. We are currently evaluating the impact of this standard on our disclosures.

In November 2024, the FASB issued ASU No. 2024-03, “Disaggregation of Income Statement Expenses (Subtopic 220-40).” The ASU requires public entities to disaggregate, in a tabular presentation, certain income statement expenses into different categories, such as purchases of inventory, employee compensation, depreciation and intangible asset amortization. The guidance is effective for fiscal years beginning after December 15, 2026, with early adoption permitted, and may be applied retrospectively. The Company is currently evaluating the impact of adopting the new ASU on our consolidated financial statements and related disclosures.

All other new accounting pronouncements that have been issued, but not yet effective, are currently being evaluated and at this time are not expected to have a material impact on our financial position or results of operations.

Internal controls and procedures

We are not currently required to comply with the SEC’s rules implementing Section 404 of the Sarbanes-Oxley Act and are therefore not required to make a formal assessment of the effectiveness of our internal control over financial reporting for that purpose. Upon becoming a public company, we will be required to comply with the SEC’s rules implementing Section 302 of the Sarbanes-Oxley Act, which will require our management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of our internal control over financial reporting. However, we will not be required to make our first assessment of our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act until our second annual report on Form 10-K after we become a public company.

Furthermore, our independent registered public accounting firm is not yet required to formally attest to the effectiveness of our internal control over financial reporting and will not be required to do so for as long as we are an “emerging growth company” pursuant to the provisions of the JOBS Act. See “—Implications of being an emerging growth company.”

117

preparation of HMH B.V.’s financial statements for the years ended December 31, 2022 and 2023, due in part to inadequate time to fully monitor and test such internal controls system implemented in the fourth quarter of 2023, we identified certain deficiencies in the design and operation of internal control over financial reporting that constituted material weaknesses. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected and corrected on a timely basis. The material weaknesses specifically resulted from the (i) insufficient number of qualified personnel with appropriate GAAP and SEC financial reporting and internal controls expertise; (ii) insufficient risk assessment relating to the financial reporting process; (iii) insufficient design, implementation and operating effectiveness of IT general controls and business process controls; and (iv) insufficient segregation of duties.

Inflation

During 2022, 2023 and 2024, we experienced significant inflation in costs related to our products and services as a result of global inflationary trends. Ongoing inflationary pressures have resulted in, and may continue to result in, additional increases to the costs of goods, services, labor and personnel, which in turn could cause our capital expenditures and operating costs to rise, as well as a scarcity of certain products and raw materials, including steel. Like others in our industry, in 2022, 2023 and 2024, we faced, and continue to face, considerable inflation in the cost of raw materials and personnel. To date, these costs have largely been passed on to customers and we do not believe that the effects of inflation have had a material effect on our business, financial condition or results of operations. However, if our costs remain subject to significant inflationary pressures, we may not be able to offset such increased costs through price increases. Our inability or failure to offset any such cost increases in the future could have a material adverse effect on our business, financial condition and results of operations.

Sustained levels of high inflation caused the U.S. Federal Reserve to raise its target range for the federal funds rate multiple times in 2022 and 2023, but the U.S. Federal Reserve cut rates multiple times between September and December of 2024, resulting in a total aggregate increase of 425 basis points. The U.S. Federal Reserve’s target rate is currently between 4.25% and 4.50%. Future rate hikes from the U.S. Federal Reserve (or its

118

equivalent in other nations) or other efforts to curb inflationary pressure on the costs of goods and services could have the effect of raising the cost of capital and depressing economic growth.

Off-balance sheet arrangements

Currently, we do not have any off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, cash requirements or capital resources.

Quantitative and qualitative disclosures about market risk

Commodity price risk

The market for our products and services is indirectly exposed to fluctuations in the prices of oil and natural gas to the extent such fluctuations impact drilling and completion activity levels and thus impact the activity levels of our customers in the E&P industry. We do not believe that we are particularly exposed to short-term fluctuations. We do not currently intend to hedge our indirect exposure to commodity price risk.

Foreign currency exchange rate risk

A portion of our revenues is derived internationally and, accordingly, our competitiveness and financial results may be impacted by foreign currency fluctuations where revenues and costs are denominated in local currencies rather than U.S. dollars. For the three months ended March 31, 2025, 66.9% of our revenues were denominated in foreign currencies. For the years ended December 31, 2024 and 2023, 63.9% and 62.0%, respectively, of our revenues were denominated in foreign currencies. We hedge currency risk in relevant projects using forward contracts.

We use a sensitivity analysis model to measure the potential impact on revenue and net income (loss) of a 10% adverse movement of foreign currency exchange rates against the U.S. dollar over the previous year. Based upon this model, a 10% decrease would have resulted in a decrease in revenues of $13.3 million and a decrease in net income of $3.8 million for the three months ended March 31, 2025. Based upon this model, a 10% decrease would have resulted in a decrease in revenues of $53.9 million and a decrease in net income of $17.4 million for 2024. There can be no assurance that the exchange rate decrease projected above will materialize as fluctuations in exchange rates are beyond our control.

Interest rate risk

We are primarily exposed to interest rate risk through the Revolver. As of March 31, 2025 and December 31, 2024, we had zero and $14.4 million, respectively, of aggregate principal amount outstanding under the Revolver, which bears interest at the compounded SOFR plus an applicable margin. We do not currently intend to hedge our exposure to interest rate risk.

Credit risk

Our customers are predominantly drilling contractors and drilling rig manufacturers, drilling rig owners and drilling rig operators in all segments, such as offshore and onshore oil and gas companies and production shipyards. Changes in economic, regulatory or other conditions may increase our overall credit risk from counterparties. We manage credit risk by analyzing the counterparties’ financial condition prior to accepting new customers and prior to adjusting existing credit limits.

Global energy demand and crude oil production

Our products and services primarily serve customers that support or are engaged directly in the exploration and production of oil and gas. As a result, the demand for our products and services is tied to the level of drilling activity and the spending of E&P operators associated with supplying hydrocarbons.

While there is a concerted effort in much of the world to increase the share of energy provided by renewable energy sources, it is expected that oil and gas will remain a critical component of the energy mix through 2050. According to the IEA’s 2024 World Energy Outlook, global energy consumption is expected to increase to 533 EJ by 2050, a 20% increase from 2023 levels and a 41% increase from 2010 levels. The increase in energy consumption is expected to largely be driven by expanding populations and increasing energy intensity of emerging economies. The largest increase in consumption is expected to come from electricity, with demand increasing from 91 EJ in 2023 to 168 EJ in 2050. Oil and natural gas will continue to be critical components of electricity generation and demand, as both are expected to increase through 2030 before beginning to plateau and decline gradually through 2050.

During the recent slowdown in global economic activity resulting from COVID-19 and related volatility in commodity prices, global investment activity by E&P operators decreased as the industry focused on cash preservation. Rystad Energy estimates that 2020 global upstream capital expenditures decreased 33% from 2019 levels to approximately $470 billion. Capital expenditure levels remained below 2019 levels until 2023. This resulted in the first notable annual decline in the supply of hydrocarbon liquids (crude oil, natural gas

120

liquids and related commodities) in recent history. Rystad Energy estimates that hydrocarbon liquids demand decreased approximately 9% from 2019 to 2020. However, as a result of the long lead times associated with oil and gas production, the retraction in spending during the period and the strong economic recovery from the shutdowns relating to COVID-19, Rystad Energy expects a supply shortfall in 2025 of approximately 0.6 MM Bbls/day, in addition to the 1.4 MM Bbls/day experienced in 2024.

Global production of hydrocarbons is expected to grow through 2030 to support increasing demand in power generation, transportation fuel and other consumer end products and growing energy intensity of emerging economies in South America, Africa and Asia. Total global production is expected to increase from 168 MM Boe/day in 2024 to 187 MM Boe/day in 2030. While overall global supply is expected to increase by approximately 19.3 MM Boe/day, or 12%, from 2024 to 2030, offshore production is expected to grow 16% over that same period, or 7.5 MM Boe/day.

LOGO

Source: Rystad Energy UCube

It should be noted, however, that, beyond the 2030 time horizon, Rystad Energy expects that the lack of investment in exploration-directed activity during the last cycle could result in a more pronounced shortfall in global liquids supply in a conservative demand scenario. Rystad Energy has analyzed the potential liquids demand under a +2.2 degree Celsius and +1.9 degree Celsius level (versus pre-industrial levels) and found that the currently identified

121

discoveries and the existing under-development and producing fields will not be sufficient to support demand. Deepwater offshore is one of the few target areas with the potential to meaningfully increase identified resources.

Source: Rystad Energy UCube

The expected shift in spending towards offshore and away from land-directed activity is a reversal of the shift towards unconventional land production from 2012 to 2015, which was largely driven by the significant resource identified in U.S. shale, and in particular, in the Permian basin where horizontal drilling and hydraulic fracturing allowed operators to extract significantly greater volumes from the reservoir. Given rapid decline rates in shale and tight oil reservoirs and decreasing productivity from onshore non-OPEC production, Rystad Energy expects to see offshore deepwater production as the main contributor to global non-OPEC oil supply beyond 2027.

122

As previously noted, operators prioritized investments in shorter-cycle, unconventional projects primarily in the United States. This resulted in the rapid increase in production in the United States over this period and decline in offshore-directed spending beginning in 2014 and 2015. Rystad Energy estimates that shale and tight oil spending accounted for 12% of total global E&P spending in 2010 and increased to 23% in 2024. However, Rystad Energy estimates that 17,500 additional offshore wells will be required to be drilled between 2024 and 2028 to meet future demand. Further, the costs of production offshore and declining productivity from U.S. shale resources have resulted in deepwater development costs being on par with those of shale resources, a marked shift from prior years.

123

In addition to the larger resource base and competitive cost profile of offshore production relative to shale activity, offshore production compares favorably to all other sources of production on an emissions basis. Deepwater production is estimated to have a GHG emissions intensity of 10 kg CO₂e per Boe, 15 to 20% below that of shale, and approximately 50% below conventional onshore. Given the ESG focus of E&P operators, the lower emissions intensity of offshore production is a further incentive to increase spending on offshore directed development.

Global onshore and offshore exploration and production

Rystad Energy estimates that to support the expected increase in demand for both oil and natural gas through 2030, offshore-directed spending will need to increase to $240 billion in 2027 from $212 billion in 2024, which is a 71% increase from the $140 billion spent in 2021, and 17,500 additional offshore wells will be required to be drilled between 2024 and 2028. Of these, approximately 3,200 are expected to be deepwater wells, which will require a floater, and the balance will be in shallow waters, thus supporting jack-up drilling rig activity. This increase in investment serves as a notable tailwind for our business.

Global offshore drilling market dynamics

The offshore contract drilling industry provides drilling, workover and well construction services to E&P companies primarily using jack-up rigs, semisubmersible rigs and drillships. The offshore drilling market is generally segmented into two large categories: shallow and deepwater drilling. Shallow water drilling, which is typically conducted in water depths of up to approximately 450 feet, tends to be in areas relatively close to shore and utilizes jack-up rigs. Deepwater activity requires a semisubmersible or drillship (collectively referred to as “floaters”), which are capable of drilling in water depths of up to 12,500 feet.

Semisubmersibles and drillships (floaters) market

Floaters include semisubmersibles and drillships. A semisubmersible rig is a floating platform supported on pontoons and columns submerged below sea level while the operating deck is above sea level. The rig features a ballasting system that can vary the draft of the partially submerged hull from a shallow transit draft, to the required, deeper, operational draft. Semisubmersibles move on location by tugs or, if self-propelled, can relocate independent of such vessels. The rig stays in position by either a conventional mooring system or a computer-controlled system known as a dynamic positioning system. A drillship is a self-propelled ship-shaped vessel including a drilling package and station-keeping equipment. Drillships are kept on location by either a conventional mooring system or a dynamic positioning system. Typically, drillships operate in deeper waters and are suitable for operations in remote locations because of their mobility and large deck load capacity. Once on location, the drillship utilizes either anchors or a dynamic positioning system to stay on location.

Prior to the aforementioned shift in activity focus in the mid-2010s, the offshore floater market experienced significant growth and investment. Rystad Energy estimated that 236 floaters, primarily midwater moored semisubmersible rigs, had been delivered globally from 1970 to 2005, when the technology developed. Since 2005, orders were placed for 209 modern floaters. 188 have been placed in service as of 2024, which includes six rigs that were ordered prior to 2005, and the balance of 14 remains in shipyards. Notably, there have been effectively no newbuild orders for floaters since 2014. Demand for our products, either in the form of replacement spare parts or upgrades to equipment in need of major refurbishment, increases as these floaters continue to age and are subject to the wear-and-tear of continued use, and our aftermarket services are critical to maintaining the safety, reliability and productivity of these older floaters. Additionally, some rig contractors may choose to replace the entire topside package on an older floater but retain the existing hull, which we can provide through the sale of one of our comprehensive drilling projects.

In addition to the shortage of newbuild floater activity in recent years, 197 floaters have been retired from the global fleet since 2010, leaving the available number of floaters at 187 by year-end 2024, according to Rystad Energy. We are poised to supply our integrated, comprehensive drilling projects for any newbuild rigs manufactured to replace aging or retired floaters.

The rapid pace of retirements in the industry has resulted in a significant recovery in both day rates and utilization levels across the available fleet. In particular, day rates and utilization for modern 6th generation rigs and above (defined as rigs capable of operating in over 7,500 feet of water, with dynamical positioning and built in the last 20 years) have displayed a notable recovery. Day rates for these modern high-spec floaters have recovered to levels not seen since the prior peak in the mid-2010s. Recent contract announcements crossed the $500,000 threshold at the end of 2023 and continued to climb through the course of 2024 with multiple one-year contracts in the U.S. Gulf of Mexico at or above $515,000 per day and the 8th generation Deepwater Atlas securing a one-year $635,000 contract at the end of 2024.

According to Rystad Energy, marketed contracted utilization rates for the current floaters are reported to be in the low-80% range as of December 2024 due in large part to the retirement of floaters. Utilization rates at this level have not been seen since 2014. The current fleet includes 23 cold stacked floaters. Of the cold stacked fleet, 10 were cold stacked prior to 2020, and of the remaining 13 cold stacked rigs, five are 2nd, 4th and 5th generation rigs that are not competitive in the modern drilling market. The remaining eight cold stacked floaters are potential reactivation candidates at current day rates.

Jack-up market

Jack-up rigs are bottom-supported and self-elevating units with three or four movable legs that can be extended, or ‘‘jacked,’’ above or below the drilling deck, or hull. Jack-up rigs are mobile and their legs can be lowered to the ocean floor until a foundation is established for support. Jack-up rigs are towed to the offshore drill site with the hull, which is a water-tight barge that floats on the water’s surface, lowered to the water level, and the legs extended above the hull. When the rig reaches the drill site, the crew jacks the legs downward through the water and into the sea floor. This anchors the rig and allows the hull and the drilling deck to be elevated to a height well above the waves. When the transit distances are long, the jack-up rig is placed on heavy-lift vessels for transport.

The jack-up market is categorized between standard and premium jack-ups. Standard or commodity jack-up rigs are generally capable of operating in water depths of less than 350 feet or without an independent leg cantilever design. Premium jack-ups are characterized by independent-leg cantilever designs and are generally rated to work in water depths in excess of 350 feet. Both standard and premium jack-ups are suitable for use in benign drilling environments, such as the U.S. Gulf of Mexico, Mexico and Southeast Asia. High-spec jack-ups are a subset of premium jack-ups that may feature a larger lifting capacity (hook load capacity of in excess of 1.5 million pounds, larger mud pumps and those capable of operating in water depths in excess of 350 feet) and that are rated to withstand operations in harsh environments such as those seen in the North Sea or capable of drilling very deep, high pressure gas wells. Jack-up rigs are also generally suited to working in shallow water environments.

Similar to the floater market, the jack-up market experienced significant investment through the mid-2010s with 345 jack-ups ordered between 2005 and 2016 and 332 delivered to the fleet since 2005, which includes 14 ordered prior to 2005. However, it should be noted that 26 of the jack-ups ordered between 2013 and 2016 are still in the shipyard with deliveries scheduled through 2036, indicating that these rigs are unlikely to enter service.

During the period from 2010 to 2022, 211 jack-ups rigs were formally retired from the global fleet, partially offsetting newbuilds being delivered from shipyards. The current global jack-up fleet stands at 492 rigs as of December 2024. Of these, 293 are premium or high-spec rigs, of which only 273 were delivered since 2000.

Rystad Energy estimated that the current jack-up fleet stands at 492 rigs, while demand sits at 369 rig years as of December 2024, which has resulted in the contracted utilization for the jack-up fleet to increase to 84% as of December 2024, a significant increase from the secular low of 67% during the fourth quarter of 2017 and the first quarter of 2018.

According to Rystad Energy, the market for premium and high-spec jack-ups is even tighter than the utilization would indicate for the broader jack-up fleet as operators increasingly show a willingness to pay for, and preference for, modern jack-up rigs given the increased operational window and efficiency of these rigs relative to older and lower-spec rigs in the fleet.

We believe that there is limited availability of premium, modern jack-ups that could be supportive of continued newbuild activity in the near term as operator requirements continue to increase and the availability of suitable jack-up rigs remains limited.

Critical minerals

The global critical minerals industry encompasses the extraction of valuable metals and minerals from the earth’s surface. It plays a crucial role in various sectors, including energy, manufacturing and infrastructure, automotive, aerospace, plastics and, in particular, the electrification and infrastructure for renewable energy. Accordingly, the critical minerals industry plays an active and growing role in our portfolio of products, specifically our slurry pumps. These pumps are used to extract and transport material, an activity that is increasingly crucial to supporting electrification infrastructure build-out initiatives.

Near-term demand for critical minerals already reflects this increasing demand. According to S&P Global Commodity Insights, demand for lithium and cobalt is expected to see year-over-year growth in 2024 of 30.6% and 15.6%, respectively. Electric vehicles require around six times more minerals than conventional cars, and an offshore wind power plant requires 13 times more minerals than a gas-fired power plant. Each of these illustrates alternative energies’ massive dependence on mineral supplies. Electric vehicles drive much of this demand, with global demand increasing from just 684 GWh estimated in 2023 to a projected 1,014 GWh in 2024. Nickel mining output is forecasted to grow 9.8% year-over-year in 2024, and copper production has increased 3% to 6% across the value chain in the first quarter of 2024. A significant ramp in mining activity is required to meet the increasing demand from large-scale electrification and renewable energy initiatives.

128

Source: S&P Global Markets Intelligence

From 2023 to 2028, the demand for key mineral production from end markets that we currently serve, including copper, lithium, cobalt and nickel, is expected to increase significantly. S&P Global Commodity Insights expects to see the supply of these critical minerals increase 6.7 megaton per year between 2023 and 2028, driven by a 4.1 megaton per year increase to 30.1 megaton per year for copper; a 1.3 megaton per year increase to 2.2 megaton per year for lithium; a 1.1 megaton per year increase to 4.5 megaton per year for nickel; and a 0.13 megaton per year increase to 0.34 megaton per year for cobalt.

We expect continued growth in the demand for our existing portfolio of mining related equipment, primarily our slurry pumps, as mining companies invest in expanding their facilities and developing recently-identified sites.

Having an asset-light business allows us to generate a strong Adjusted ROCE, a metric that we use to evaluate the profitability of our capital employed in our business operations. During the three months ended March 31, 2025 and the year ended December 31, 2024, our Adjusted ROCE was 3.5% and 19.7%, respectively. Adjusted EBITDA and Adjusted ROCE are non-GAAP financial measures.

Our history and brands

Many of our product lines have been in existence for decades, providing us opportunities to pursue improvements and innovations as our customers grow and undertake new challenges. Wirth developed its first mud pump in 1905, and since then has continuously worked to improve the portfolio of mud pump designs. Wirth was also one of the pioneers of pile top drill rigs and reverse circulation drilling. Hydril Company, a name derived from the term “Hydraulic Drilling Equipment,” was formed in 1933. During that decade, it produced the first hydraulically operated BOP. We reached another milestone when we began delivering drawworks and pyramid masts and substructures for onshore rigs in 1950.

The long history of our brands and high customer recognition enables us to pursue R&D efforts to innovate existing product and service offerings for our customers, such as the fully electric BOP in development that we believe is the first of its kind and will pave the way for safer, more efficient and environmentally sustainable drilling operations. As compared to traditional hydraulic systems, a fully electric BOP minimizes downtime and

132

reduces maintenance costs by providing active monitoring, real-time data and remote-control capabilities. We are also developing several other cutting-edge technologies and solutions, such as a newly designed rotating control device for managed pressure drilling and enhanced pressure assisted shearing for BOPs.

commonly, a significant capital upgrade to an existing drilling rig. Project sales are largely tied to the offshore rig newbuild cycle, particularly to the construction of floaters and jack-ups. Such projects entail substantial commissioning, manufacturing and installation, and thus shipyards or other customers seeking to outfit a newbuild or significantly upgrade an existing drilling rig prefer OEMs with differentiating expertise and reliability such as us. Production, delivery and installation on a project can span from 1.5 to 3.5 years. For a newbuild rig, we can provide an entire package of drilling equipment, which, based on the previous build cycle that ended in 2015, represents a revenue opportunity of approximately $45 million in sales for a jack-up rig, approximately $200 million to $300 million in sales for a floater and approximately $15 million to $25 million in sales for a land rig.

Source: Company management

We are able to partner with customers to deliver equipment sales, spare parts sales and aftermarket services through the entire operating life of a rig to provide the performance, efficiency and safety they have come to expect. Such partnership is exemplified by our CSAs with customers, which are long-term agreements under which we provide a tailored, unique solution to our customers’ aftermarket service needs for between five and ten years after initial installation. We provide our customers with transparent pricing and payment structures that are predictable. We leverage our experience and expertise to take advantage of predictive analytics and continuous certification to improve equipment availability and reduce operational costs for our customers while also limiting the impact of any potential supply chain slowdowns on our customers’ equipment. With our CSA offerings, for example, we have partnered with our customers to enhance BOP system availability by transferring the responsibility for BOP performance, including the management and servicing of equipment, to us. In addition to mitigating risks associated with downtime and repair costs, our customizable structures can be fine-tuned to address long-term ownership costs.

Customers and end markets

139

As the OEM of critical drilling equipment, our customers typically purchase equipment and services from us at regular intervals to support and service their existing assets. Our sales of equipment to new customers and for new drilling rigs also allow us to continually expand this installed base of equipment. In addition to our sales offices and direct sales efforts, we incorporate distributors and manufacturing sales representatives into our sales and marketing channels in certain limited locations to market our various offerings. Our top five customers accounted for approximately 52.0%, 42.0% and 32.9% of our total consolidated revenues for the three months ended March 31, 2025 and the years ended December 31, 2024 and 2023, respectively. During the three months ended March 31, 2025, three customers accounted for 14.4%, 12.3% and 11.9% of our revenues for such period, respectively, and during the year ended December 31, 2024, one customer accounted for 18.2% of our revenues for such year. We expect to maintain our relationship with this customer. During the year ended December 31, 2023, no individual customer accounted for more than 10% of our revenues for such year.

We expect our customer mix to remain consistent with recent results as global drilling activity in the coming years, particularly offshore, is expected to continue to recover from cyclical trough levels seen from 2015 to 2021. In particular, due to the higher concentration of our equipment being deployed in offshore and international drilling, we expect to be the beneficiaries of an expected 20% growth in offshore and international spending from 2023 to 2030, according to Rystad Energy. We do not currently anticipate a meaningful increase in de novo newbuild offshore rig construction activity in the near term, except for specific contract tenders to support expanded rig demand in the Middle East and Southeast Asia.

Our competitive strengths

We have a number of strengths that we believe will help us successfully execute our business strategies, including:

Global provider of innovative drilling equipment, digital solutions and services

We offer a broad portfolio of innovative drilling equipment, digital solutions and drilling rig lifecycle services designed to enhance the safety, efficiency and reliability of our customers’ operations. We deliver many of our products and services through highly recognized brands, including Hydril, VetcoGray, Wirth and Maritime Hydraulics, which have been trusted names in the energy industry for decades (in the case of Wirth, for more than 125 years). The Hydril brand, for example, produced the first hydraulically operated BOP in 1937, and Hydril continues to manufacture some of the most advanced annular BOPs for both onshore and offshore applications. The long history of our brands and high customer recognition enables us to pursue R&D efforts to continuously improve existing product and service offerings for our customers while also developing innovative new technologies, such as our commercial 20,000 psi BOP capability and a fully electric BOP. With development, manufacturing and service locations distributed throughout 16 countries, our global integrated operations facilitate the efficient delivery of our products to the operating sites of our customers and servicing of our installed base of equipment.

Large global installed base and integrated operations provide recurring and resilient aftermarket service and spare parts revenues

leverage our expertise and predictive analytics to design a unique blend of products and services for our customers aimed to increase equipment reliability, decrease downtime, reduce operational costs and ultimately lead to increased productivity and revenues for our customers. As a result of our extensive experience, track record of safety and reliability, comprehensive suite of offerings and global service network, we are a partner of choice for many of the largest independent E&P companies, national oil companies, drilling contractors, service providers and shipyards.

Exposure to strong expected growth in offshore and international onshore oil and gas drilling markets

With our large installed base and global presence, we are well positioned to capitalize on favorable dynamics in the oil and gas drilling industry, particularly in the offshore market where the substantial majority of our equipment is deployed today. According to Rystad Energy, after years of underinvestment, global greenfield and brownfield oil and gas capital expenditures are projected to be over $700 billion in each of 2025, 2026 and 2027, an increase of almost 60% as compared to 2020. As global capital expenditures for the oil and gas industry increase, the offshore rig market is also approaching activity levels not seen in nearly a decade. Rystad Energy forecasts a compounded annual growth rate of over 6% for floater rigs between 2024 and 2027. Such increase in oil and gas exploration and drilling activity is expected to result in increased demand for our equipment, aftermarket services and spare parts. Further, due to the longer cycle times associated with offshore oil and gas projects as compared to onshore activity, we are well poised to benefit from the duration and stability of offshore activity. We believe our recurring revenues from aftermarket services and spare parts will benefit from the expected increase in offshore activity.

Our strategy

We intend to achieve our primary business objectives by successfully executing on the following strategies through a combination of organic and inorganic growth investments:

Leverage global footprint and large installed base to capture growth in offshore drilling capital expenditures

Our integrated operations, including the provision of aftermarket services, enable us to understand the needs of our customers and anticipate areas for growth in our core market. We will seek to capture the expected increase in capital expenditures and drilling activity in the offshore oil and gas market through our global footprint of manufacturing and supply chain facilities near key markets and our large installed base.

Continue to enhance customer offerings through both improvement of existing technologies, increased digitalization and expansion into additional offshore services

Leverage historical capability to capture growth and market share in onshore drilling capital expenditures

143

penetration of new equipment sales for land drilling. The onshore drilling market is relatively more fragmented with a more diverse customer base than the offshore drilling market and represents a largely untapped aftermarket opportunity for us. We have the ability to provide a broad suite of products (over 110,000 drawings of parts are available), spare parts and repair services that are compatible with equipment provided by most major manufacturers. Recent expansion in the Middle East further enhances this capability, and we are pursuing multiple additional marketing channels to increase this activity on a global basis.

Utilize industry expertise and manufacturing capabilities to continue growth in current onshore and subsea mining businesses

Expand into adjacent markets that are consistent with our core competencies

Capitalize on management experience to grow business through acquisitions and integration

HMH B.V. was formed through the combination of Baker Hughes’s Subsea Drilling Systems pressure control business and Akastor’s MHWirth drilling equipment business. Our management team successfully combined these businesses and quickly established our corporate infrastructure to support the new company. Our management team has extensive M&A and integration experience in prior roles at other companies. Given management’s experience and prior track record, we are well positioned to recognize and capitalize on trends in the industry.

Our global reach and footprint position us well to identify, source, acquire and integrate businesses that can help us continue to grow in core and adjacent markets, as exemplified by the Drillform Acquisition. We believe there is a substantial opportunity set of potential acquisition candidates that will be available over the next several years.

144

Continue to use conservative balance sheet approach and target businesses with light capital needs

Competition

Our industry is highly competitive. Competition primarily involves factors such as safety and reliability of products and services offerings, technical expertise, development of innovative technological solutions, maintenance of customer relationships, ability to execute on complex projects and operations within acceptable time and cost boundaries and other related factors. In our main market segment of providing support to existing drilling rigs, we see a particularly competitive environment because our primary customers, drilling rig owners, face highly competitive day rates due to the overcapacity of available drilling rigs in the industry. As a result, the drilling rig owners must focus on their operational costs, which can lead to deferred maintenance and fewer upgrade contracts on which to bid; therefore, we must be aggressive on pricing to secure work.

We are, along with NOV Inc. (“NOV”) and Schlumberger Limited’s Cameron International (“Schlumberger”), the main providers of full equipment packages for the offshore drilling market. The offshore drilling market is becoming more highly regulated, more technologically demanding and more technologically sophisticated than the onshore market. As a result, offshore operators require highly engineered equipment and technical support services to keep their operations running safely, efficiently and productively. We believe that we are well-positioned to continue supporting and building our presence in the offshore drilling market as a result of our fully integrated suite of mission-critical equipment solutions, spare parts, highly technical expertise, aftermarket services offerings and long experience in the industry. Our comprehensive product offerings, manufacturing expertise and leading-edge technology allow us to provide customers with integrated topside drilling packages for jack-ups, floaters and platforms and integrated pressure control systems, both at surface and subsea. Our primary competitors for these products include Canrig Drilling Technology Ltd., Huisman Equipment B.V., KCA DEUTAG Drilling Group Limited, NOV, Schlumberger, Worldwide Oilfield Machine Inc. and several smaller OEMs of specific pieces of equipment. Within the global offshore drilling fleet, we have the second-largest installed base of topside drilling equipment and risers and the third largest installed base within the main pressure control equipment categories, including BOPs and diverters.

We are also growing our market presence in the onshore drilling space and are now among the leading OEMs in multiple equipment categories within the onshore drilling and pressure control equipment spaces. The onshore drilling market has less stringent regulation and less demanding technology requirements, which have allowed more companies to enter the onshore drilling equipment manufacturers market, resulting in a more fragmented market than the offshore drilling market. Many players, in addition to NOV and Schlumberger, compete against us in most product segments. Smaller manufacturers and Chinese-based manufacturers can

145

more effectively compete with us onshore. Companies like Canrig Drilling Technology Ltd., Drillmec India Pvt. Ltd., Honghua Group, KCA DEUTAG Drilling Group Limited, Rongsheng Machinery Manufacture Ltd. and Worldwide Oilfield Machine Inc., among others, have significant presence in many regions in which we deliver our products and services. To effectively compete in the onshore market, we must be aggressive in bidding.

Raw materials

We believe that materials and components used in our operations are generally available from multiple sources and that we are not dependent on any single source of supply for those materials and components. While we believe that we will be able to make satisfactory alternative arrangements in the event of any interruption in the supply of materials and components, we may not always be able to do so. Shortages and transportation and supply disruptions can adversely impact supply of our manufacturing raw materials, as well as delivery of finished goods and transportation of our personnel for services, and as a result our products or services may be disrupted or delayed, which could have a material adverse effect on our business, operations and financial condition. Should our current suppliers be unable or unwilling to provide the necessary parts, raw materials or equipment or otherwise fail to deliver the products timely and in the quantities required, any resulting delays in the provision of our products or services could have a material adverse effect on our business, financial condition, results of operations and cash flows. If we are unable to purchase raw materials for our products on a timely basis to meet the demands of our customers, our existing customers may terminate their contractual relationships with us, or we may not be able to compete for business from new or existing customers, which, in each case, could have a material adverse effect on our business, financial condition, results of operations and cash flows. Supply chain bottlenecks, such as those experienced as a result of the COVID-19 pandemic, may continue to persist as a consequence of evolving geopolitical trends.

The prices that we pay for raw materials may be affected by, among other things, energy, steel and other commodity prices; tariffs and duties on imported materials; economic sanctions; and foreign currency exchange rates. We have experienced rising, declining and stable prices for milled steel and standard grades in line with broader economic activity, and we have generally seen specialty alloy prices continue to rise, driven primarily by escalation in the price of the alloying agents. We have generally been successful in our efforts to mitigate the financial impact of higher raw materials costs on our operations by applying surcharges to, and adjusting prices on, the products that we sell. Higher prices and lower availability of steel and other raw materials that we use in our business may adversely impact future periods.

Research and development

We believe that we have been, and will continue to be, at the forefront of technological and digital innovation in the drilling industry. Our current R&D activities are conducted in Norway, Germany and the United States. We actively invest in R&D efforts and are developing several cutting-edge technologies and solutions, such as hybrid energy solution rigs, riserless drilling, a newly designed rotating control device for managed pressure drilling, enhanced pressure assisted shearing for BOPs and an electric BOP. The focus of our R&D activities is the optimization of existing products and the exploration of new opportunities.

We are committed to making those necessary investments to improve the capabilities of existing core products and to create new product offerings to fuel organic growth. In recent years, our primary R&D project was to build upon the success of our current wireline casing shear ram (“WCSR”) for our 18-inch 15,000 psi ram BOP by introducing the WCSR-X^™ shearing ram, which extended the shearing capacity of existing BOPs to up to an 18-inch outside diameter pipe and reduced required shear force up to 48%.

We have three major R&D projects currently in progress:

•

development of a rotating control device along with associated equipment to enable open water, riserless drilling. We believe it will be a “first of its kind” deployment that was enabled by our acquisition of some key technology through our purchase of Electrical Subsea Drilling AS (“ESD”) in 2022;

•

design and construction of a testbed for the development of the electric BOP actuators, motors and controllers for use in offshore surface (platforms and jack-ups), subsea and land applications. Like the rotating control device, the key technology driver for this development was our purchase of ESD. This testbed is also being used to bring in potential partners to aid in the design and qualification effort; and

•

development of automation and digitalization solutions and digitally-powered services to improve customer efficiency, reduce emissions and improve customer competitiveness.

We continue to explore potential partnership avenues to aid in our development efforts. New R&D efforts for 2025 and beyond include development and production of the fully electric BOP for both offshore surface (platforms and jack-ups) and subsea use, for which we are working with several publicly-listed oil and gas companies to help fund development. We expect a significant portion of funding to come from operator partners. As with the development of the rotating control device, the development of the electric BOP has been enabled by our acquisition of ESD. Additionally, we are developing next-generation elastomers for oilfield sealing applications, including those outside our current space, in cooperation with a major operator.

148

Our R&D objectives are focused on improving safety and efficiency, reducing emissions and cost and improving customers’ competitiveness. In pursuit of these objectives, we are exploring automation and other digital control solutions across various drilling functions.

We also invest in developing digital and automation solutions that can be integrated on operating rigs throughout the global market, such as DrillPerform, RiCon, DrillCERT, SeaLytics and DEAL, which use real-time data and analytics that allow us to better understand our customers’ needs, provide strategic recommendations and offerings, assist with lowering their costs and assist with critical decision-making. In recent years, we have developed integrated digital control solutions that enable remote drilling operations and increase automation in the drilling process. We provide our customers with the ability to integrate such digital solutions into their existing systems, which leads to mutually beneficial relationships with our customers.

Our innovative equipment offerings and integrated digital solutions create value for our customers by increasing efficiency, reducing emissions, decreasing downtime, reducing cost and enhancing safety. We will continue pursuing technological and digital advancements that we believe will lead to additional avenues for growth and enhance our position as the partner of choice for our customers. As we experience strong demand for our adjacent markets, part of our R&D efforts has focused on improving and further developing existing products, such as slurry pumps portfolio, equipment and systems for seabed mining and large pile top drill rigs. Additional work has been made to exploring new opportunities in adjoining industries where we see a good fit with our competency and our core “DNA.” This work has resulted in key priorities and market leads in 2024 that we will continue to explore in 2025. We plan to focus our development efforts in the coming years on what we believe are “game-changing” technologies like open water drilling and the electric BOP.

Backlog and inbound orders

We generate revenue and inbound orders from a combination of sales of projects and products, sales of services and sales of spare parts. Services are typically sold directly to our customers, either through individual transactions at the time of service or through long-term CSAs. During the three months ended March 31, 2025, we derived 42.1% of our revenue from services, 30.3% of our revenue from sales of spare parts and 27.6% of our revenue from sales of projects and products. During 2024, we derived 43.4% of our revenue from services, 29.4% of our revenue from sales of spare parts and 27.2% of our revenue from sales of projects and products. Due to the nature of our business, including the time required to manufacture projects and products and the long-term nature of some of our aftermarket service contracts (such as CSAs), we capture inbound orders for projects, products and services (such as CSAs) under backlog.

Backlog for our business includes unfilled customer orders for projects, products and services, excluding any purchase order that provides the customer with the ability to cancel or terminate without incurring a substantive penalty. Services backlog includes sales related to CSAs and other long-term aftermarket service contracts. While the length of these contracts can be up to ten years, our backlog includes the estimated value of the contract through the current fiscal year and does not account for the possibility of bonuses or escalation clauses (which might cause the realized amount to exceed the amount captured in backlog). Services backlog also includes the estimated amount of unsatisfied performance obligations for time and material agreements, material services agreements, multi-year maintenance programs and other services agreements, excluding any order that provides the customer with the ability to cancel or terminate without incurring a substantive penalty.

There can be no assurance that the backlog amounts will ultimately be realized as revenue, or that we will earn a profit on backlog work. Our backlog as of March 31, 2025 was $464.2 million, of which $185.1 million was attributable to projects and products and $279.1 million was attributable to services. While the full contract values are not included in our backlog, as of March 31, 2025, we had $47.2 million in contract value related to CSAs, thus providing us with enhanced levels of predictability and visibility into revenue from services for years to come.

149

Operating risks and insurance

Our operations are subject to hazards inherent in the oil and natural gas and mining industries, including accidents, breakdowns, blowouts, explosions, fires, oil spills and hazardous materials spills. These conditions can cause personal injury or loss of life, damage to or destruction of property, equipment, natural resources, the environment and wildlife and interruption or suspension of operations, among other adverse effects.

Despite what we view as our strong safety record and our efforts to maintain strong safety standards, we conduct our operations in a potentially dangerous drilling and production setting and from time to time have suffered accidents and similar incidents in the past and it is possible that we could experience accidents and incidents in the future. In addition to the property damage, personal injury and other losses from these accidents, the frequency and severity of these incidents may affect our operating costs and insurability and our relationships with customers, employees, regulatory agencies and other parties. Any significant increase in the frequency or severity of these incidents, or the general level of compensation awards or regulatory enforcement sanctions, could adversely affect the cost of, or our ability to obtain, workers’ compensation and other forms of insurance, and could have other material adverse effects on our financial condition, our results of operations or our ability to operate.

We maintain a portfolio of insurance policies to protect our core businesses against loss of property, business interruption, injury to personnel and liability to third parties for such losses as per industry standards. Risks insured generally include loss or damage to physical assets, such as buildings, plants, equipment and work in progress, and business interruption resulting therefrom, bodily injury to and death of employees and third-party liabilities. Certain types of losses are generally not insured by us because they are either uninsurable or not economically insurable, such as losses caused as a result of inability to deliver on time or at the right quality, or losses occasioned by willful misconduct, criminal acts, fines and penalties and various perils associated with war and terrorism. Our insurance policies may not be sufficient to adequately insulate us from a claim that exceeds policy limits or against every circumstance or hazard to which we could be subject. An uninsured loss, a loss that exceeds the limits of our insurance policies or a succession of such losses could have a material adverse effect on our business, operations and financial condition.

We typically enter into agreements with our customers governing the provision of our services and use of our products, which usually include certain indemnification provisions for losses resulting from operations depending on the party that is negligent or at fault. Additionally, our agreements with customers often provide certain warranties for the products and services that we sell. The warranty period is normally between 12 and 30 months depending on the specific customer contract and terms. Based on historical warranty expense experience, the warranty provision is estimated at 1.4% of product cost in long-term project construction contracts and 1% of revenue for single product equipment sales.

Environmental, health and safety regulation

Our operations are subject to domestic (including U.S. federal, state and local) and international laws and regulations with regard to air, land and water quality and other environmental protection, compliance and occupational health and safety matters. Numerous federal, state and local governmental agencies, such as the EPA, issue laws and regulations that often require difficult and costly compliance measures that carry substantial administrative, civil and criminal penalties for non-compliance and may result in injunctive action. These laws and regulations may require the acquisition of permits, authorizations or licenses before commencing operations; restrict the types, quantities and concentrations of various substances that can be stored, transported, disposed of or released into the environment in connection with our operations; limit or prohibit construction or drilling activities on certain lands lying within wilderness, wetlands, ecologically or

150

seismically sensitive areas and other protected areas or due to governmental moratoriums on drilling; require action to prevent, control or remediate pollution from current or former operations; result in the suspension or revocation of necessary permits, licenses and authorizations; or require that additional pollution controls be installed and impose substantial liabilities for pollution resulting from our operations or related to our owned or operated facilities. Liability under such laws and regulations is often strict and can also be joint and several. Neighboring landowners and other third parties may file claims for personal injury and property damage allegedly caused by the release of hazardous substances, hydrocarbons or other waste products into the environment. Changes in environmental, health and safety (“EHS”) laws and regulations occur frequently, and any changes that result in more stringent and costly requirements could materially adversely affect our operations and financial position, as well as the oil and natural gas industry in general. We have not experienced any material adverse effect from compliance with current EHS requirements. This trend, however, may not continue in the future. Changes in standards of enforcement of existing laws and regulations, as well as the enactment and enforcement of new legislation, may require us and our customers to modify, supplement or replace equipment or facilities or to change or discontinue present methods of operation. Our environmental compliance expenditures, our capital costs for environmental control equipment and the market for our products may change accordingly.

During 2024 and the three months ended March 31, 2025, 24.4% and 23.1%, respectively, of our revenue was derived from Norway, including the Norwegian Continental Shelf. In Norway, the Norwegian Pollution Control Act (“NPCA”) applies to all industries and is the cornerstone of Norway’s environmental legislation. The Norwegian Environment Agency (“NEA”) administers the NPCA, and all pollution is prohibited unless an application is specifically approved by the NEA. All emissions into air, water and soil are covered by the NPCA, including CO₂ emissions. In relation to manufacturing, specific emissions limitations are set by the NEA, and the NEA’s express permission must be obtained before commencing any operations. The NEA and the various country governors enforce compliance with the various environmental rules and regulations set forth under the NPCA. If inspections uncover non-compliance, a deadline for rectifying the matter will be imposed, and such non-compliance will subject the offender to follow-up supervision and possible fines.

Norway’s environmental and climate policies generally track that of the EU. In 2021, the European Commission adopted a series of legislative proposals depicting how it intends to achieve climate neutrality in the EU by 2050, including the intermediate target of an at least 55% net reduction in GHG emissions by 2030. These proposals have also been referred to as the “Fit for 55” package. Many of the Fit for 55 proposals have now been enacted into EU law and are currently being implemented in the Member States of the EU and European Economic Area, including Norway. This legislative package introduces new measures and revises several pieces of the EU’s pre-existing climate-related legislation, including the EU Emissions Trading System (“EU ETS”), the Effort Sharing Regulation and transport and land use legislation.

In Norway, the Norwegian Accounting Act has required large enterprises to report on corporate social responsibility. However, the ESG reporting requirements that apply to certain companies in Norway and EU are set to be broadened as a result of the CSRD. The CSRD was adopted in the EU in January 2023, and amended the pre-existing ESG reporting requirements that were set out in the Non-Financial Reporting Directive. The CSRD impacts in-scope companies in a phased manner, with the first companies becoming subject to its provisions from January 2024. In March 2024, legislation was proposed to the Norwegian Parliament to adopt the CSRD model. This legislation was adopted by the Norwegian Parliament on June 11, 2024 and came into effect on November 1, 2024. Under the CSRD, companies may be required to disclose a broad range of information in relation to sustainability and ESG topics, including in relation to their business model, sustainability objectives, progress, management’s involvement in sustainability, policies, due diligence processes, adverse impacts, mitigation measures, sustainability risks and relevant indicators. Additionally, the CSRD contains provisions regarding the disclosure of transition plans for climate change mitigation, alignment with a sustainable economy and the Paris Agreement’s goal of limiting global warming to 1.5°C and the reporting of GHG emissions (including Scope 1, Scope 2 and Scope 3), if climate change is recognized as a material concern for the reporting entity following a double materiality assessment.

151

The NTA requires enterprises to conduct due diligence assessments pertaining to fundamental human rights and decent working conditions in their own operations and in their value chain. The NTA applies to larger enterprises that are resident in Norway and that offer goods or services in or outside Norway. It also applies to larger foreign enterprises that offer goods or services in Norway and that are liable to tax in Norway pursuant to Norwegian legislation. In addition to carrying out due diligence assessments, companies must publish an account of the due diligence assessments and have a duty to provide information.

On July 25, 2024, the CS3D entered into force. The CS3D introduces mandatory requirements relating to both human rights and environmental impacts in the supply chains of in-scope companies. However, the provisions of the CS3D will not take effect until at least July 26, 2027. Following the CS3D’s entry into force on July 25, 2024, it will likely be incorporated into Norwegian law and will likely lead to amendments of the NTA, for example, by extending the focus of due diligence assessments to also cover environmental impacts.

Hazardous substances and waste handling

The Resource Conservation and Recovery Act (“RCRA”) and comparable state statutes regulate the generation, transportation, treatment, storage, disposal and cleanup of hazardous and non-hazardous wastes. We are required to manage the transportation, storage and disposal of hazardous and non-hazardous wastes generated by our operations, including our operations at customer sites, in compliance with applicable laws, including RCRA.

The Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”), also known as the Superfund law, imposes joint and several liability, without regard to fault or legality of the original conduct, on classes of persons who are considered to be responsible for the release of a hazardous substance into the environment. These persons can include the current and former owner (or lessee) or operator of the site where the release occurred, and anyone who disposed of or arranged for the disposal of a hazardous substance released at the site. We currently own, lease or operate numerous properties used for manufacturing and other operations. In the event of a release from these properties, under CERCLA, RCRA and analogous state laws, we could be required to remove substances and wastes, remediate contaminated property or perform remedial operations to prevent future contamination even if the releases are not from our operations. Such liability could require us to engage in litigation to defend the claims and to allocate our proportionate share of liability, if any. In addition, neighboring landowners and other third parties may also file claims for personal injury and property damage allegedly caused by releases into the environment. Any obligations to undertake remedial operations in the future may increase our cost of doing business and may have a material adverse effect on our financial condition and results of operations.

In Norway, if there is a danger of pollution contrary to the NPCA, those who are responsible must ensure that measures are taken to prevent pollution from occurring. If pollution has already occurred, the NEA may order those who are responsible for the pollution to implement measures, such as conducting further investigations,

152

removing the pollution or limiting its effects. The NPCA does not clearly define who is considered to be responsible for older pollution, which may be particularly difficult to determine when the pollution took place many years ago. Hence, liability for older pollution has been shaped primarily by case law and by interpretation of the NPCA by the NEA and in legal theory. Any obligations to implement measures imposed by the pollution control authorities under the NPCA may have a material adverse effect on our results of operations and financial condition.

Water discharges

The Federal Water Pollution Control Act (the “Clean Water Act”) and analogous state laws restrict and control the discharge of pollutants into “Waters of the United States” (“WOTUS”). Discharges into WOTUS associated with our operations require appropriate permits and may add material costs to our operations. The adoption of more stringent criteria in the future may also increase our costs of operation. The Clean Water Act and analogous state laws provide administrative, civil and criminal penalties for unauthorized discharges and, together with the Oil Pollution Act of 1990, impose rigorous requirements for spill prevention and response planning, as well as substantial potential liability for the costs of removal, remediation and damages in connection with any unauthorized discharges.

The EU Water Framework Directive, which has been incorporated into Norwegian law, requires that Member States of the EU and European Economic Area protect and, where necessary, restore water bodies in order to reach “good status,” and to prevent deterioration. “Good status” means both good chemical and good ecological status. These obligations will have an impact on companies applying for permits, including under the NPCA, as strict limits will be set on discharges of pollutants into water.

Air emissions

The federal Clean Air Act, as amended (“CAA”), and comparable state laws and regulations regulate emissions of various air pollutants through the issuance of permits and the imposition of other requirements. The EPA has developed, and continues to develop, stringent regulations governing emissions of air pollutants from specified sources. New facilities may be required to obtain permits before work can begin, and existing facilities may be required to obtain additional permits and incur capital costs in order to remain in compliance. These laws and regulations may increase the costs of compliance for some facilities we or our customers own or operate, and federal and state regulatory agencies can impose administrative, civil and criminal penalties for non-compliance with air permits or other requirements of the CAA and associated state laws and regulations. Obtaining or renewing permits also has the potential to delay the development of oil and natural gas projects. Additional costs or delays incurred by our customers could adversely affect demand for the oil and natural gas they produce, which could reduce demand for our products and services. We believe that we are in substantial compliance with all applicable air emissions regulations and that we hold all necessary and valid construction and operating permits for our operations.

Employee health and safety

We are subject to a number of federal and state laws and regulations, including the Occupational Safety and Health Act (“OSHA”) and comparable state statutes, establishing requirements to protect the health and safety of workers. In addition, the OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of the federal Superfund Amendment and Reauthorization Act and comparable state statutes require that information be maintained concerning hazardous materials used or produced in our operations and that this information be provided to employees, state and local government authorities and the public. Substantial fines and penalties can be imposed and orders or injunctions limiting or prohibiting certain

153

operations may be issued in connection with any failure to comply with laws and regulations relating to worker health and safety.

Climate change

Various international, national and state governments and agencies are currently evaluating or promulgating climate-related legislation and other regulatory initiatives that would restrict GHG emissions. These regulatory measures include, among others, adoption of cap and trade regimes, carbon taxes, increased efficiency standards and incentives or mandates for renewable energy. Because our business depends on the level of activity in the oil and gas industry, existing or future laws, regulations, treaties or international agreements related to GHG emissions and climate change, including incentives to conserve energy or use alternative energy sources, could have a material adverse effect on our business, financial condition and results of operations if such laws, regulations, treaties or international agreements negatively affect global demand for oil and gas. Consideration of further legislation or regulation may be impacted by the Paris Agreement, which was announced by the parties to the U.N. Framework Convention on Climate Change in December 2015 and calls on signatories to set progressive GHG emission reduction goals. In April 2021, the United States announced that it was setting an economy-wide target of reducing its GHG emissions by 50-52% below 2005 levels in 2030. On December 13, 2023, in connection with COP 28, the first global stocktake of progress towards emissions reductions goals under the Paris Agreement was published. The stocktake agreement calls on parties, including the United States, to contribute to transitioning away from fossil fuels, reduce methane emissions and increase renewable energy capacity. Further, many state and local leaders have stated their intent to intensify efforts to support the international climate commitments. These commitments could further reduce demand and prices for fossil fuels produced by our customers. More recently, however, on January 20, 2025, the Trump Administration issued an executive order that initiated the process to withdraw the United States from the Paris Agreement, mandated ending the United States’ financial commitments under the UN Framework Convention on Climate Change, and revoked the U.S. International Climate Finance Plan. In addition to the executive order mentioned above, as of January 25, 2025, the Trump Administration had issued a series of executive orders that signal a shift in the United States’ energy and climate change policies. Among other directives, such executive orders: (i) direct federal agencies to identify and exercise emergency authorities to facilitate conventional energy production, transportation and refining, and call for the use of emergency regulations to expedite energy infrastructure projects; (ii) promote energy exploration and production on federal lands and waters; (iii) mandate a review of existing regulations that may burden domestic energy development; and (iv) pause the disbursement of funds appropriated through the IRA 2022 and the Infrastructure Investment and Jobs Act. It is not possible to predict the impact of the Trump Administration on these climate and energy initiatives at this time. While the Trump Administration may seek to reverse some or all of the initiatives advanced by the Biden Administration, it is unknown whether such reversals will ultimately be successful, and these or additional changes in the future could impact our business and operations, and those of our customers. Additionally, despite the Trump Administration’s stated opposition to some of these regulations and initiatives, individual states have the right to enforce their own laws and, in some cases, federal laws, independent of the federal government.

The IRA 2022 contains billions of dollars in incentives for the development of renewable energy, clean hydrogen, clean fuels, electric vehicles, investments in advanced biofuels and supporting infrastructure and carbon capture and sequestration, among other provisions. These incentives could accelerate the transition of the economy away from the use of fossil fuels towards lower or zero-carbon emissions alternatives, which could decrease demand for, and, in turn, the prices of, oil and natural gas, which could have a material and adverse impact on us. In addition, the IRA 2022 imposes the first ever federal fee on excess methane emissions from sources required to report their GHG emissions to the EPA, including those sources in the offshore and onshore petroleum and natural gas production and gathering and boosting source categories. The final rules regarding

154

the Waste Emissions Charge were published by the EPA on November 18, 2024. On March 14, 2025, however, President Trump signed a Joint Resolution of Disapproval under the Congressional Review Act to prohibit the EPA’s Waste Emissions Charge rules from taking effect. If the Waste Emissions Charge takes effect, it could increase our customers’ operating costs, which could adversely impact our business.

On March 8, 2024, the EPA published its final GHG monitoring, reporting and emissions control rules for the oil and natural gas industry, and almost one-half of U.S. states have taken measures to reduce emissions of GHGs, primarily through the development of GHG emission inventories and regional GHG cap-and-trade programs. In addition, states have imposed increasingly stringent requirements related to the venting or flaring of gas during oil and natural gas operations.

On March 6, 2024, the SEC adopted a new set of rules that require a wide range of climate-related disclosures, including material climate-related risks, information on any climate-related targets or goals that are material to the registrant’s business, results of operations or financial condition, Scope 1 and Scope 2 GHG emissions on a phased-in basis by certain larger registrants when those emissions are material and the filing of an attestation report covering the same, and disclosure of the financial statement effects of severe weather events and other natural conditions, including costs and losses. Multiple lawsuits have been filed challenging the SEC’s new climate rules, which have been consolidated in the U.S. Court of Appeals for the Eighth Circuit. On April 4, 2024, the SEC issued an order staying the final rules until judicial review is complete. On March 27, 2025, the SEC voted to end the defense of the rules in the litigation. On April 4, 2025, a group of 18 intervenor-respondent states and the District of Columbia moved to hold the cases in abeyance until the SEC amends or rescinds the regulations, which motion was granted by the Eighth Circuit in an order issued on April 24, 2025. While the ultimate outcome of legal challenges and any resulting changes to the final rules are not yet known, we cannot predict the costs of implementation or any potential adverse impacts resulting from the rulemaking. To the extent this rulemaking is implemented, which is uncertain at this time, we could incur increased costs relating to the assessment and disclosure of climate-related risks, and we cannot predict how any information disclosed under the rules may be used by financial institutions or investors. Additionally, while the SEC’s new climate rules may ultimately not be implemented, individual states may continue to impose climate-related disclosure mandates.

The EU’s CSRD, adopted in 2023, has a much broader scope than the SEC’s new climate rules and requires in-scope companies to publish reports on how their business and value chains impact the environment and society, as well as the social and environmental risks and opportunities to which they are subject. The CSRD also includes the disclosure of Scope 3 emissions (which were left out of the final SEC climate rules), to the extent that climate change is determined to be a material topic for the Company as part of a double materiality assessment. We have begun implementing policies and procedures to comply with these expansive new requirements beginning in 2025 for financial periods beginning on or after January 1, 2024.

On July 25, 2024, the CS3D entered into force. The CS3D requires the use of risk-based due diligence to mitigate “adverse environmental and human rights impacts” in an in-scope company’s “chain of activities,” including certain activities of its business partners. The CS3D also mandates the adoption of climate transition plans. Nonetheless, the provisions of the CS3D will not take effect until at least July 26, 2027. France and Germany have also adopted laws requiring large companies to carry out human rights and environmental due diligence, while similar laws have been proposed in other EU Member States, such as Belgium, the Netherlands and Austria. Further, the NTA, which took effect on July 1, 2022, requires mapping actual and potential risks of adverse impacts on decent working conditions and human rights.

155

revised reporting standards (ESRS). For the CS3D, the European Commission’s proposal includes, among other things, a postponed application for certain companies and less stringent requirements relating to due diligence and climate transition plans. On April 17, 2025, the proposed postponements relating to the obligations of the CSRD and the CS3D entered into force through Directive (EU) 2025/794, which requires EU member states to adopt the changes into domestic legislation by December 31, 2025 at the latest. For the other proposed simplifications of the CSRD and the CS3D to enter into force, approval by the European Parliament and the Council of the European Union is needed. As of May 2, 2025, it is uncertain whether or not these simplifications will be approved.

In general, these regulatory changes do not appear to affect us in any material respect that is different, or to any materially greater or lesser extent, than other companies that are our competitors. However, to the extent our customers are subject to these or other similar proposed or newly enacted laws and regulations, the additional costs incurred by our customers to comply with such laws and regulations could impact their ability or desire to continue to operate at current or anticipated levels, which could negatively impact their demand for our products and services. In addition, any new laws or regulations establishing cap-and-trade or that favor the increased use of non-fossil fuels—such as the IRA 2022—may dampen demand for oil and natural gas production and lead to lower spending by our customers for our products and services. Similarly, to the extent we are or become subject to any of these or other similar proposed or newly enacted laws and regulations, we expect that our efforts to monitor, report and comply with such laws and regulations, and any related taxes imposed on companies by such programs, will increase our cost of doing business and may have a material adverse effect on our financial condition and results of operations. Moreover, any such regulations could ultimately restrict the exploration and production of fossil fuels, which could adversely affect demand for our products.

There have been efforts in recent years to influence the investment community, including investment advisors, institutional lenders, insurance companies and certain sovereign wealth, pension and endowment funds and other groups, by promoting divestment of fossil fuel equities and pressuring lenders to limit funding and insurance underwriters to limit coverages to companies engaged in the extraction of fossil fuel reserves. Such environmental activism and initiatives aimed at limiting climate change and reducing air pollution could interfere with our business activities, operations and ability to access capital. Furthermore, claims have been made against certain energy companies alleging that GHG emissions from oil and natural gas operations constitute a public nuisance under federal and state common law. As a result, private individuals or public entities may seek to enforce environmental laws and regulations against certain energy companies and could allege personal injury, property damages or other liabilities. While our business is not currently a party to any such litigation, we could be named in actions making similar allegations. An unfavorable ruling in any such case could significantly impact our operations or our customers’ operations and could have an adverse impact on our financial condition.

The EU ETS is a cornerstone of the EU’s climate policy and has been incorporated into Norwegian law via the Norwegian Greenhouse Gas Emission Trading Act since 2008. The EU ETS is a ‘cap-and-trade’ system, whereunder the overall volume of GHGs that may be emitted by installations covered by the system is limited by a cap on emission allowances. The cap is gradually tightened so that total emissions are reduced. Within the cap, companies are allocated or buy emission allowances, which they can trade as needed. The cap on the total volume of emissions ensures that emission allowances have a market value. At the end of each year, companies must surrender enough allowances to cover all their emissions or face fines as a penalty for the excess emissions. The price of EU ETS allowances has fluctuated over the years and reached a peak in early 2023 with approximately 100 EUR per ton of CO₂. As of May 14, 2025, the price per ton of CO₂ was approximately EUR 73. The EU ETS was subject to material amendments as part of the Fit for 55 package of policies, which included bringing additional sectors within the scope of the EU ETS, and also accelerating the phase out of free allowances and the reduction in the cap.

Offshore drilling

Various new regulations intended to improve offshore safety systems and environmental protection have been issued since 2010, which have increased the complexity of the drilling permit process and may limit the opportunity for some operators to continue deepwater drilling in the U.S. Gulf of Mexico, which could have an adverse impact on our customers’ activities. For example, in 2016, the DOI’s Bureau of Safety and Environmental Enforcement (“BSEE”) published its first well control rule, focused on BOP requirements and included reforms in well design, well control, casing, cementing, real-time well monitoring and subsea containment. In 2019, the BSEE, under the Trump Administration, published a revised well control rule and on August 23, 2023, the BSEE published a newly revised well control rule, which builds on the 2016 rule and revises or rescinds certain modifications that were made in the 2019 rule. The 2023 well control rule clarifies BOP system requirements and modifies certain specific BOP equipment capability requirements. In addition, on April 24, 2024, the DOI’s Bureau of Ocean Energy Management published a final risk management and financial assurance rule that substantially revises financial assurance requirements applicable to offshore oil and gas operations. The new well control rule and new financial assurance requirements may increase our customers’ operating costs significantly and impact our customers’ ability to obtain leases, thereby reducing demand for our products.

Further, there is ongoing uncertainty regarding the long-term outlook for the U.S. Gulf of Mexico region, as a result of a prior temporary ban on leasing of U.S. federal lands imposed by President Biden in 2021. The temporary ban has been lifted and the Biden Administration resumed selling leases to drill for oil and gas on federal lands in April 2022, but with an 80% reduction in the number of acres offered and an increase in the royalties companies must pay to drill. In August 2023, the DOI proposed a scaled back offshore lease sale for certain areas in the Gulf of Mexico due to concerns related to an endangered whale population in the area. The exclusion of certain lease blocks from the sale was successfully challenged in court, and the DOI was ordered to hold the lease sale at its original scale. This decision was upheld by the U.S. Court of Appeals for the Fifth Circuit on November 14, 2023, and the sale was held on December 20, 2023. On January 6, 2025, President Biden issued a Memorandum of Withdrawal pursuant to the Outer Continental Shelf Lands Act of the entire U.S. East Coast, the eastern Gulf of Mexico, the Pacific off the coasts of Washington, Oregon and California, and additional portions of the Northern Bering Sea in Alaska from oil and gas leasing, which the Trump Administration sought to reverse by executive order in January 2025. On January 26, 2024, the Biden Administration implemented a temporary pause on the DOE’s review of pending decisions for authorization to export LNG to non-Free Trade Agreement countries while the DOE reviews and updates the underlying analyses for such decisions using more current data to account for considerations like the environmental and climate change impacts of LNG. The temporary pause was then overturned by the U.S. District Court for the Western District of Louisiana in July 2024, and the Trump Administration restarted the review of new LNG export terminals via executive order in January 2025. On April 24, 2024, the DOI published a final rule to revise the Bureau of Land Management’s oil and gas leasing regulations, which revises fiscal terms of the onshore federal oil and gas leasing program, including for bonding requirements, royalty rates and minimum bids. If the new regulations, policies, operating procedures and possibility of increased legal liability, as well as the general uncertainty related to federal oil and gas leases in or near the Gulf of Mexico, are viewed by our current or future customers as a significant impairment to expected profitability on projects or an unjustifiable increase in risk, they could discontinue or curtail their offshore operations, thereby adversely affecting the demand for our equipment and services, which, in turn, could adversely affect our financial condition, results of operations or cash flows.

Given the wide geographical reach of our business activities, the laws and regulations in several other jurisdictions may also be relevant to our provision of aftermarket services, sales of spare parts and sales of projects and products, and the applicable legal framework and its enforcement practices may vary across different jurisdictions. For instance, we may be subject to the NPCA and the Norwegian Maritime Act of 24 June

1994 for our activities in Norway. Environmental protection laws and regulations have become increasingly stringent. Such laws and regulations are continuously evolving both nationally and internationally, particularly within the EU, to accommodate the advancing technical standards and heightened requirements for safety and environmental preservation in the energy sector. International regulations governing safety, materials discharge into the environment and other aspects of environmental protection encompass various regulations, such as the International Convention for the Safety of Life at Sea 1974, the International Convention for the Prevention of Pollution from Ships 1973, the International Safety Management Code for the Safe Operation of Ships and Pollution Prevention, the International Convention on Civil Liability for Oil Pollution Damage 1969, the International Convention on Civil Liability for Bunker Oil Pollution Damage 2001, the International Convention for the Control and Management of Ships’ Ballast Water and Sediments 2004, the Convention on the Prevention of Marine Pollution by Dumping of Waste and other Matters 1972 (as amended by the 1996 London Protocol), and the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers 1978.

Human capital and employees

We are committed to investing in our human capital and creating a supportive work environment that enables our employees to thrive. We believe that by prioritizing the well-being, development and engagement of our workforce, we can drive innovation, deliver exceptional products and services and achieve long-term success.

Workforce profile

As of March 31, 2025, we had 2,078 employees, including 1,128 manufacturing and servicing personnel and 950 corporate, administrative and management personnel. Of this total population, approximately 602 employees in Norway, Germany and Mexico are employed under their respective collective bargaining agreements. Although we have not experienced any labor disruptions, strikes or other forms of labor unrest in connection with such personnel and we consider our employee relations to be good, there can be no assurance that labor disruptions by such employees will not occur in the future.

30.8% of our employees work in North America, 45.7% in Europe, 12.6% in Central and South America, 6.6% in the Middle East and 4.4% in Asia and Australia. Our workforce is diverse and inclusive, comprising of individuals from different backgrounds, cultures and experiences. We believe that diversity strengthens our organization and enables us to better serve our customers and communities.

Ethics and compliance

We operate globally and acknowledge that bribery and corruption may pose a risk. We are committed to upholding ethical and lawful practices in all aspects of our operations, recognizing our responsibility to our employees, stockholders and the communities in which we operate.

Our policies prohibit any form of corruption, including bribery, trading in influence, facilitation payments, network corruption (nepotism), illegal kick-backs or any similar illegal activities. Our Anti-Bribery and Corruption Policy provides guidance for employees to assess risks, understand relevant laws and report concerns.

We conduct annual training on our policies, which includes anti-bribery and corruption training. Additionally, we evaluate the potential exposure to bribery and corruption when engaging with customers and suppliers, and we reject partnerships where we perceive unacceptably high risks. Furthermore, we conduct audits of our suppliers to confirm their compliance with our policies and take corrective actions when necessary.

158

Health, safety, security and environment

We recognize HSSE as a key component of our organizational culture, and we strive to cultivate an HSSE-focused mindset among our employees and in connection with our activities. Our employees are expected to advance our corporate HSSE values and principles, including caring for the environment and prioritizing the safety and well-being of our employees and other stakeholders. This commitment to HSSE is highlighted by the fact that our board of directors receives and discusses a safety report at the beginning of each quarterly board meeting. Additionally, our Chief Executive Officer, Chief Financial Officer and Chief Administration Officer, General Counsel and Corporate Secretary continuously monitor and update our safety policies and best practices.

We also work towards achieving ESG standards by providing solutions that increase efficiency and reduce our carbon footprint, growing a diverse workforce and protecting human rights.

Employee engagement and well-being

We prioritize the well-being and satisfaction of our employees. We believe that a healthy work-life balance is essential for productivity and overall happiness. To promote employee engagement, we offer flexible work arrangements, wellness programs and employee assistance programs.

We also value open communication and encourage feedback from our employees. We conduct regular pulse surveys and feedback sessions to understand their needs, concerns and suggestions. This helps us create a supportive and inclusive work environment where everyone feels heard and valued.

Talent acquisition and development

We have a comprehensive talent acquisition strategy in place to attract and hire the best candidates for our organization. We focus on identifying individuals who align with our values, possess the necessary skills and expertise and demonstrate a commitment to continuous learning and growth.

Once onboarded, we provide our employees with various opportunities for professional development and advancement. We offer training programs, mentorship initiatives and career development resources to support their growth within the Company.

Compensation and benefits

We provide competitive compensation packages tailored by location that reflect the skills, experience and contributions of our employees. Our compensation structure is designed to reward performance and promote fairness. We also offer a comprehensive benefits package that includes health insurance, retirement plans, paid time off and other perks.

Patents, trademarks and other intellectual property

Over the last several years, we have significantly invested in our research and technology capabilities, as described under “—Research and development.” As a result of these efforts, we introduced several new products and progressed on differentiating technologies that we believe will provide a competitive advantage as our customers focus on extracting oil and natural gas in the most economical and efficient ways possible, including R&D on a fully electric BOP and introduction of the WCSR-X shearing product and various digital solutions.

159

We seek patent protections for our technology when we deem it prudent, monitor for any potential infringements on patents and trademarks and aggressively pursue protection of these rights, up to and including litigation. As of May 2025, we owned over 600 U.S. and foreign patents and over 200 pending U.S. and foreign patent applications. In addition, we rely to a great extent on the technical expertise and know-how of our personnel to maintain our competitive position, and we make efforts to protect trade secrets and other confidential or proprietary information relating to the technologies we develop.

The term of individual patents depends on the legal term for patents in the countries in which they are granted. In most countries, including the United States, the patent term is generally 20 years from the earliest claimed filing date of a nonprovisional patent application in the applicable country or Patent Cooperation Treaty application. The patents in our current portfolio expire between August 27, 2025 and September 7, 2041. Once a patent expires, the protection ends, and the claimed invention enters the public domain; that is, anyone can commercially exploit the invention without infringing the patent.

Trademarks are also of considerable importance to the marketing of our products. We consider the HMH^™, MHWirth^™, Wirth^™, Hydril Pressure Control^™, Bronco^™, VetcoGray^™, mh^™, Maritime Hydraulics^™, mh-Pyramid^™, Beware^™ and Deal^™ trademarks to be important to our business as a whole. We typically register trademarks in many of the countries where the trademarked products are used or generate revenue. We are party to certain license agreements that either grant us limited rights to use certain trademarks or relate to us providing others with the license to use certain trademarks. As part of the formation of HMH B.V., we entered into worldwide, fully paid, nontransferable and non-sublicensable license agreements with a subsidiary of Baker Hughes giving us a limited right to use the terms Vetco^™ and VetcoGray^™ as trademarks on certain products traditionally sold under those trademarks and certain other intellectual property rights relating to the business line Baker Hughes contributed to HMH B.V. at the time of HMH B.V.’s formation. In addition, as part of the sale of its pressure control business to our predecessor in interest, General Electric Company, Tenaris S.A. entered into a worldwide, fully paid, nontransferable and non-sublicensable limited license agreement with Hydril USA Distribution LLC, our wholly owned subsidiary, for use of the Hydril^™ trademark with respect to pressure control products and services related thereto. These agreements contain restrictions on our use of these trademarks, which are owned by others, and we rely upon those other parties to maintain and protect them.

We also rely on trade secret laws and contracts to protect our confidential and proprietary information. To protect our information, we customarily enter into confidentiality agreements with our employees, consultants, partners, customers, potential customers and suppliers, for example. We believe our patents, trademarks and other protections for our proprietary technologies are adequate for the conduct of our business.

Cyclical nature of industry

We operate in a highly cyclical industry. Our business is particularly sensitive to factors such as oil and gas prices, the supply and demand for oil and gas, the level of exploration, development, production, investment, modification and maintenance activity and competition.

Prices for oil and gas commodities have historically been, and are expected to remain, subject to fluctuations in response to changes in the supply and demand for oil and gas, market uncertainty and a variety of other political and economic factors. Prolonged reductions in oil and gas prices typically result in decreased levels of exploration, development, production, investment, modification and maintenance activity by oil and gas companies. Any decreased levels of exploration, development and production activity or reductions or postponement of major expenditures by oil and gas companies could lead to downward pricing pressure on oil and gas service companies such as us and, therefore, could adversely affect our activity and profit.

160

Seasonality

Historically, demand for our oil and gas-related products and services have been affected by seasonal trends in levels of drilling and production activity in the oil and gas industry. Budgets of many of our customers are based upon a calendar year, and demand for our services has historically been stronger in the second and third calendar quarters when allocated budgets are expended by our customers and seasonal weather conditions are more favorable for drilling and production activities, particularly for offshore operations. Many other factors, such as national or customary holiday seasons, the expiration of drilling leases and the supply of and demand for oil and natural gas, may affect this general trend in any particular year. While we anticipate that the seasonal and other trends described above may continue, there can be no guarantee that spending by our customers will continue to follow patterns observed in the past.

Legal matters

From time to time, we are a party to ongoing legal proceedings in the ordinary course of business. We do not believe the results of currently pending proceedings, individually or in the aggregate, will have a material adverse effect on our business, financial condition, results of operations or liquidity.

so long as Akastor and its affiliates collectively beneficially own at least but less than shares of our common stock, Akastor can designate one nominee to our board of directors.

Pursuant to the Stockholders’ Agreement, we will be required to (i) include the Principal Stockholder nominees on each slate of director nominees for election in our annual meeting or special meeting proxy statement (or consent solicitation or similar document), (ii) recommend the election of such nominees to our stockholders and (iii) otherwise use our reasonable best efforts to cause such nominees to be elected to our board of directors. Each Principal Stockholder will also have the exclusive right to remove its respective designees and to fill vacancies created by the removal or resignation of its designees (unless such Principal Stockholder does not have the requisite ownership to fill such vacancies).

Furthermore, for so long as a Principal Stockholder and its affiliates collectively beneficially own at least shares of our common stock, any increase or decrease to the size of our board of directors or amendment, modification or waiver of our amended and restated bylaws that relates to the size of our board of directors will require the prior written consent of such Principal Stockholder.

See “Certain relationships and related party transactions—Stockholders’ Agreement.”

Committees of the board of directors

Upon the listing of our Class A common stock on Nasdaq, our board of directors will have three standing committees: an audit committee, a compensation committee and a nominating and governance committee. The composition and responsibilities of each of the committees of our board of directors are described below.

167

Members will serve on these committees until their resignation or until otherwise determined by our board of directors.

Pursuant to our amended and restated bylaws, our board of directors may, from time to time, establish other committees to facilitate the management of our business and operations. Pursuant to the Stockholders’ Agreement, if we establish any committee of our board of directors other than the audit committee, the compensation committee or the nominating and governance committee, such committee will consist of at least one director nominated by each Principal Stockholder if requested by such Principal Stockholder and only if such Principal Stockholder is then entitled to nominate at least one director to our board of directors. See “Certain relationships and related party transactions—Stockholders’ Agreement.”

For each committee below, the rules of the SEC and Nasdaq require us to have (i) one independent committee member (a) for the audit committee, upon the listing of our Class A common stock and (b) for each of the compensation committee and the nominating and governance committee, by the earlier of the date this offering closes and five days from the listing of our Class A common stock, (ii) a majority of independent committee members within 90 days of the effective date of the registration statement of which this prospectus forms a part and (iii) all independent committee members within one year of the effective date of the registration statement of which this prospectus forms a part.

Audit committee

Our board of directors will establish an audit committee in connection with this offering whose functions include the following:

•

assist our board of directors in its oversight responsibilities regarding the integrity of our financial statements, our compliance with legal and regulatory requirements, the independent accountant’s qualifications and independence and our accounting and financial reporting processes of and the audits of our financial statements;

•

prepare the report required by the SEC for inclusion in our annual proxy statement;

•

approve audit and non-audit services to be performed by the independent accountants; and

•

perform such other functions as our board of directors may from time to time assign to the audit committee.

Our audit committee will consist of Ms. McAllister (chairperson), Mr. Loeffler and Mr. Rabun, each of whom will satisfy the independence requirements of the Exchange Act and the Nasdaq listing standards and satisfy the financial literacy requirement for audit committee members under the Nasdaq listing standards. We anticipate that Ms. McAllister will qualify as an audit committee financial expert as defined under Item 407(d) of Regulation S-K and satisfy the financial sophistication requirement under the Nasdaq listing standards.

Prior to the listing of our Class A common stock on Nasdaq, our board of directors will adopt a written charter for the audit committee, which will satisfy the applicable rules of the SEC and the listing standards of Nasdaq. This charter will be posted on our website upon the listing of our Class A common stock on Nasdaq.

Compensation committee

Our compensation committee will consist of Mr. Rabun (chairperson), Mr. Loeffler and Ms. McAllister. This committee will establish or recommend for approval salaries, incentives and other forms of compensation for officers and directors. The compensation committee will also administer or make recommendations with respect to any long-term incentive plan that may be adopted. The specific functions and responsibilities of the compensation committee will be set forth in the compensation committee charter.

Nominating and governance committee

Our nominating and governance committee will consist of Mr. Loeffler (chairperson), Ms. McAllister and Mr. Rabun.

This charter will be posted on our website upon the listing of our Class A common stock on Nasdaq.

Compensation committee interlocks and insider participation

None of our executive officers serve on the board of directors or compensation committee of a company that has an executive officer that serves on our board of directors or compensation committee. No member of our board of directors is an executive officer of a company in which one of our executive officers serves as a member of the board of directors or compensation committee of that company.

Board role in risk oversight

Our corporate governance guidelines will provide that our board of directors is responsible for reviewing the process for assessing the major risks facing us and the options for their mitigation. This responsibility will be largely satisfied by our audit committee, which is responsible for reviewing and discussing with management and our independent registered public accounting firm our major risk exposures and the policies management has implemented to monitor such exposures, including our financial risk exposures and risk management policies.

Code of business conduct and ethics

Prior to the listing of our Class A common stock on Nasdaq, our board of directors will adopt a code of business conduct and ethics applicable to our employees, directors and officers, in accordance with applicable U.S. federal securities laws and the corporate governance rules of Nasdaq. Any waiver of this code may be made only by our board of directors or a designated committee of our board of directors and will be promptly disclosed as required by applicable U.S. federal securities laws and the corporate governance rules of Nasdaq.

Corporate governance guidelines

Prior to the listing of our Class A common stock on Nasdaq, our board of directors will adopt corporate governance guidelines in accordance with the corporate governance rules of Nasdaq.

Executive compensation

We are currently considered an “emerging growth company,” within the meaning of the Securities Act, for purposes of the SEC’s executive compensation disclosure rules. In accordance with such rules, we are required to provide a Summary Compensation Table, an Outstanding Equity Awards at Fiscal Year-End Table and a Director Compensation Table, as well as limited narrative disclosures regarding executive compensation for our last completed fiscal year. Further, our reporting obligations extend only to our “named executive officers,” who are the individuals who served as our principal executive officer and our next two other most highly compensated executive officers as of December 31, 2024.

HMH Inc. was not formed until April 2024 and, therefore, did not have executive officers in 2023. HMH Inc. has not performed operations other than tasks in connection with this offering. The operations of HMH B.V. and its subsidiaries will be carried on by HMH Inc. and its subsidiaries following this offering, and the executive officers of HMH B.V. will be our executive officers. As such, we believe that disclosure regarding our executive officers’ compensation for the full 2024 and 2023 fiscal years, which was established and paid by HMH B.V., is generally appropriate and relevant to the stockholders since we expect to generally continue these compensation arrangements following this offering and, as such, is disclosed below. Accordingly, our “Named Executive Officers” are:

•

Eirik Bergsvik, Chief Executive Officer (“CEO”);

•

Thomas W. McGee, Chief Financial Officer (“CFO”); and

•

Dwight W. Rettig, Chief Administration Officer (“CAO”), General Counsel (“GC”) and Corporate Secretary (“CS”).

2024 Compensation of named executive officers

Annual base salary

Annual base salaries are intended to provide a level of compensation sufficient to attract and retain an effective management team when considered in combination with the other components of the executive compensation program. From January 1, 2024 through June 30, 2024, Messrs. Bergsvik’s, McGee’s and Rettig’s annual base salaries were $476,904, $468,000 and $468,000, respectively, and following our board of directors’ annual review of compensation, from July 1, 2024 through December 31, 2024, Messrs. Bergsvik’s, McGee’s and Rettig’s annual base salaries were $491,211, $482,040 and $482,040, respectively. See the “Salary” column in the 2024 Summary Compensation Table for the annual base salary received by each of the Named Executive Officers in 2024. Mr. Bergsvik’s base salary was converted to U.S. dollars for the purpose of this disclosure using the average exchange ratio of 1 NOK to 0.09304 U.S. dollars for 2024.

Annual bonuses

Pursuant to their employment agreements described below, each Named Executive Officer is eligible to participate in our annual bonus program. Under our annual bonus program, participants are eligible to receive an annual cash bonus based on performance criteria established by our board of directors with a target annual incentive opportunity calculated as a percentage of their respective annual salaries. For 2024, Messrs. Bergsvik, McGee and Rettig were eligible to earn an annual performance-based bonus based on the level of achievement of the adjusted EBITDA goal set forth below, with an annual target bonus opportunity as a percentage of annual base salary equal to 100%, 75% and 75%, respectively.

Subject to achievement of International Financial Reporting Standards (IFRS) adjusted EBITDA of $135 million (U.S. dollars), 50% of the target bonus opportunity would be earned, with the percentage of the target bonus

170

opportunity earned increasing by 10% for every additional $5 million in adjusted EBITDA up to $160 million, then increasing by 5% for every additional $5 million in adjusted EBITDA up to $180 million, and finally increasing by 10% for every additional $5 million in adjusted EBITDA up to $195 million. Should adjusted EBITDA hit or exceed $220 million, the maximum payout of 200% would be achieved. To the extent adjusted EBITDA had been met between two performance levels, the payout percent would have been determined based on straight-line interpolation. To the extent adjusted EBITDA was below $135 million, no bonus would be paid.

Except as described under “—Additional narrative disclosure—Potential payments upon termination or change in control,” each Named Executive Officer must be employed on the date of payment in order to be eligible to receive an annual bonus.

Based on our 2024 adjusted EBITDA results, the 2024 annual performance-based bonuses were earned at 108% of target performance; see the “Non-equity incentive plan compensation” column in the 2024 Summary Compensation Table for the 2024 annual bonus earned by each of our Named Executive Officers.

Equity awards

We have granted phantom awards to key employees, including our Named Executive Officers, as described below. Recipients are required to satisfy service-based and, for certain awards, performance-based requirements to vest in their awards, and the awards will be paid only if a “liquidity event” occurs as described in more detail below. The value of the award paid will be based on the value of the Company at the time of a liquidity event relative to the value of the Company at the time of grant. A “liquidity event” is defined as a change in control or an IPO (each, as defined in the award agreements), in either case, that occurs before the earliest of (i) the eighth anniversary of grant, (ii) the date on which the recipient violates any restrictive covenant to which the recipient is subject and (iii) the date of the recipient’s termination, except as otherwise set forth in the award agreements and described below. In the event of a recipient’s termination for “cause” (as defined in the award agreements) prior to a liquidity event, such recipient’s awards will be forfeited, even if the vesting requirements had been met prior to such termination.

In the event of a change in control, the service-based vesting requirements will be deemed satisfied and the awards will be paid in cash or, in the discretion of our board of directors, in whole or in part in the same form of transaction proceeds received in connection with the change in control. In the event of an IPO, the awards will be paid in shares of our Class A common stock. The consummation of this offering will constitute an “IPO” under the award agreements. In either type of liquidity event, the level of achievement of the performance-based vesting criteria may be deemed satisfied at a specified level at the time of the liquidity event, as described in more detail below.

Recipients of phantom awards are subject to 12-month post-termination non-competition, non-solicitation (of employees, independent contractors and business relationships) and non-interference restrictions. Additionally, recipients are subject to non-disparagement and confidentiality restrictions. For additional information regarding the treatment of Messrs. McGee’s and Rettig’s phantom awards in connection with certain terminations of employment, see “—Additional narrative disclosure—Potential payments upon termination or change in control.”

Founders’ Awards

Effective January 31, 2022, we granted and issued phantom awards to employees, including the Named Executive Officers, subject to a service-based vesting requirement to remain employed through the date of a liquidity event (the “Founders’ Awards”). Based on a $600 million valuation of the Company’s equity, Messrs. Bergsvik’s, McGee’s and Rettig’s Founders’ Award values would be $700,000, $900,000 and $900,000, respectively. The consummation of this offering will result in the vesting of the service-based requirements of the Founders’ Awards.

171

2022 LTI program

Effective September 1, 2022, we granted and issued phantom awards that are 50% subject to the Named Executive Officer satisfying service-based vesting requirements only (the “2022 Time-based LTI”) and 50% subject to satisfaction of service- and performance-based requirements (the “2022 Performance-based LTI” and, together with the 2022 Time-based LTI, the “2022 LTI Awards”) and that are paid on the occurrence of a liquidity event (as described under “—Equity awards”). Based on a $600 million valuation of the Company’s equity, Messrs. Bergsvik’s, McGee’s and Rettig’s award values would be $600,000, $375,000 and $375,000, respectively. The service-based requirements with respect to the 2022 Time-based LTI are satisfied one-third on each of September 1, 2023, September 1, 2024 and September 1, 2025, and the 2022 Performance-based LTI may be earned up to 200% of target depending on the Company’s EBITDA growth as compared to the EBITDA growth of a set of peer companies over the three-year period from September 1, 2022 through August 31, 2025 and subject to the recipient’s continued service throughout such three-year period.

If a liquidity event occurs prior to August 31, 2025, any unvested portion of the 2022 Time-based LTI will vest and the 2022 Performance-based LTI will vest at the target level of performance, respectively. In the event a recipient is terminated other than for cause prior to a liquidity event, the recipient will keep the vested portion of his or her 2022 LTI Award, which will be paid as described herein. Any unvested portion of his or her 2022 LTI Award will be forfeited upon termination.

2023 LTI program

Effective September 1, 2023, we granted and issued phantom awards that are 50% subject to the Named Executive Officer satisfying service-based requirements (the “2023 Time-based LTI”) and 50% subject to the satisfaction of performance-based requirements (the “2023 Performance-based LTI” and, together with the 2023 Time-based LTI, the “2023 LTI Awards”). Based on a $700 million valuation of the Company’s equity, Messrs. Bergsvik’s, McGee’s and Rettig’s award values would be $570,000, $356,250 and $356,250, respectively. The service-based requirements with respect to the 2023 Time-based LTI are satisfied one-third on each of September 1, 2024, September 1, 2025 and September 1, 2026, and the 2023 Performance-based LTI may be earned up to 200% of target depending on the Company’s EBITDA growth as compared to the EBITDA growth of a set of peer companies over the three-year period from September 1, 2023 through August 31, 2026 and subject to the recipient’s continued service throughout such three-year period.

In the event of a change in control (which does not include an IPO) that occurs after August 31, 2026, the 2023 LTI Awards, as earned, pay out. If a change in control occurs on or prior to August 31, 2026, any unvested portion of the 2023 Time-based LTI will vest and the 2023 Performance-based LTI will vest at the target level of performance, respectively, and will pay out in connection with the change in control. An IPO will not accelerate the vesting or payment of the 2023 LTI Awards. In the event of an IPO, the 2023 LTI Awards are eligible for payment at the time the applicable time-based and performance-based requirements are satisfied. In the event a recipient is terminated other than for cause prior to a liquidity event, the recipient will keep the vested portion of his or her 2023 LTI Award, which will be paid as described herein. Any unvested portion of his or her 2023 LTI Award will be forfeited upon termination.

2024 LTI program

Effective as of September 1, 2024, we granted and issued phantom awards (the “2024 LTI Awards”) with substantially the same terms as the 2023 LTI Awards; provided that, with respect to the 2024 LTI Awards, the date on which the service-based vesting requirements and performance period, respectively, commenced was September 1, 2024 and the change in control measurement date is August 31, 2027. Based on a $1.0 billion valuation of the Company’s equity, Messrs. Bergsvik’s, McGee’s and Rettig’s award values would be $570,000, $356,250 and $356,250, respectively.

Outstanding equity awards at fiscal year-end

The Company did not have any share-denominated awards outstanding as of December 31, 2024. However, the Founders’ Awards, 2022 LTI Awards, 2023 LTI Awards and 2024 LTI Awards were outstanding as of such date, which, as described above, are dollar-denominated awards that are cash-settled, in the event of a change in control, or stock-settled, in the event of an IPO. The value of these awards fluctuates with, and is ultimately determined based on, the value of the Company at the time of a liquidity event relative to the value of the Company at the time of grant. Accordingly, these awards do not cover a discernible number of shares of our Class A common stock and, therefore, the aggregate estimated value of these awards as of December 31, 2024 (and not an underlying share count) are included in the table below.

Retirement benefits

United States

We maintain a qualified 401(k) retirement savings plan for all eligible employees, including Messrs. McGee and Rettig, which allows participants to defer a percentage of cash compensation up to the maximum amount allowed under IRS guidelines. We make discretionary matching contributions to our 401(k) plan, generally equal to 100% of the first 6% of the employee’s salary deferred (i.e., a 6% total match), which matching contributions are immediately vested. 401(k) plan participants are always fully vested with respect to their contributions to the plan.

Norway

Pension scheme. We maintain a defined contribution pension scheme for eligible employees, including Mr. Bergsvik, pursuant to which the employer contributes an amount corresponding to defined percentages of annual cash salary up to 12 times the base amount in the National Insurance, currently NOK 124 028, subject to annual adjustments. The pension scheme also provides for certain other elements such as disability pension. The pension scheme is within the basic requirements under Norwegian law (the Act on Defined Contribution Schemes) for tax favored pension schemes.

Contractual pension scheme (AFP). The AFP scheme covers employees in companies subject to a collective bargaining agreement that includes AFP regulations, including us. Mr. Bergsvik is eligible to participate in the AFP scheme. The AFP scheme provides additional lifelong pensions to employees. The employee must be at least 62 years old in order to start receiving the pension and fulfill certain mandatory requirements, including inter alia that the employee must be employed in a business party to the scheme when he or she reaches the age of 62 years and must have been employed in such business for at least seven of the last nine years. Employees receiving the AFP scheme can continue to work. The AFP scheme is financed by both the affiliated companies and the Norwegian government. Rules and requirements regarding pension rights and for the financing of the AFP scheme are laid out by the AFP statutes.

Potential payments upon termination or change in control

Each of the Named Executive Officers’ employment agreements provides for certain payments upon a termination of their employment.

Mr. Bergsvik

Either the Company or Mr. Bergsvik may terminate Mr. Bergsvik’s employment by providing the other party three months’ notice. If Mr. Bergsvik’s employment is terminated by the Company for a reason other than cause (as determined by the Company) or Mr. Bergsvik resigns as a result of the Company unilaterally implementing fundamental changes to his responsibilities or duties, the Company will pay Mr. Bergsvik an amount equal to six months’ base salary (the “Bergsvik Severance Payment”), which will be paid monthly in accordance with the Company’s regular payroll practices. In the event Mr. Bergsvik breaches any of these restrictive covenants, described under “—Additional narrative disclosure—Employment agreements—Eirik Bergsvik employment agreement,” he will be required to repay the Company an amount equal to the Bergsvik Severance Payment and will be required to pay liquidated damages equal to one month’s base salary for each month of breach.

Messrs. McGee and Rettig

Each of the McGee Employment Agreement and the Rettig Employment Agreement provides that, upon a termination of the employment of Messrs. McGee or Rettig, as applicable, for any reason, he will (i) receive (a) any

176

earned but unpaid base salary, (b) accrued vacation pay, (c) reimbursement for any unreimbursed business expenses and (d) accrued and vested benefits under any employee benefit plan in which he participates (subject to the terms of the plan) and (ii) remain eligible to participate in any Company-sponsored health insurance plans in accordance with U.S. law.

In addition, if the employment of Messrs. McGee or Rettig, as applicable, is terminated without “Cause” or for “Good Reason” (each as defined in his employment agreement), he will be eligible to receive a lump sum payment equal to three times the sum of (a) his base salary and (b) his average annual cash bonus received for the last three years prior to termination. Additionally, any time-based equity, phantom or long-term incentive awards will become vested, and any performance-based equity, phantom or long-term equity incentive awards will remain outstanding and eligible to vest.

Messrs. McGee and Rettig are subject to post-termination restrictive covenants as described under “—Additional narrative disclosure—Employment agreements—Thomas W. McGee and Dwight W. Rettig employment agreements.”

Recovery of erroneously awarded compensation

Our board of directors will adopt a policy for the recovery of erroneously awarded compensation, or “clawback” policy, applicable to executive officers, which will become effective on the effective date of the registration statement of which this prospectus forms a part. The policy will implement the incentive-based compensation recovery provisions of the Dodd-Frank Act as required under the listing standards of Nasdaq, and will require recovery of incentive-based compensation received after the effectiveness of the policy by current or former executive officers during the three fiscal years preceding the date it is determined that the Company is required to prepare certain accounting restatements, including to correct an error that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. The amount required to be recovered will be the excess of the amount of incentive-based compensation received over the amount that otherwise would have been received had it been determined based on the restated financial measure.

Additionally, our annual bonus program provides that, in the event any “material misconduct” results in any error in financial information used in the determination of annual bonus payments and the effect of the error was that it increased the amount of compensation paid, our board of directors may recover such increased amount. If there is a material restatement of our financial statements that affects the financial information used to determine the amount of annual bonus payments, our board of directors may take whatever action it deems appropriate to adjust such amounts. Material misconduct includes conduct that adversely affects the Company’s financial condition or results of operations or conduct that constitutes fraud or theft of Company assets, any of which requires the Company to make a restatement of its reported financial statements.

Director compensation table

The sole director of HMH Inc. and, other than Mr. Rabun, the members of the board of directors of HMH B.V. have not received any compensation for serving as a director prior to this offering. In connection with his appointment as a member and Chairman of HMH B.V.’s board of directors as of October 21, 2024, prior to the consummation of this offering, Mr. Rabun will receive from HMH B.V. a cash retainer in the annualized amount of $75,000 for his service as a member of HMH B.V.’s board of directors and an additional cash retainer in the annualized amount of $50,000 for his service as Chairman of HMH B.V.’s board of directors (for an aggregate annualized retainer equal to $125,000), each of which will be paid in quarterly installments, based on calendar quarters, in arrears on a prorated basis for any partial portion of a quarter. In addition, Mr. Rabun will receive a retainer equal to $175,000 (the “additional retainer”), which will become payable on the earliest of Mr. Rabun’s

177

resignation from HMH B.V.’s board of directors prior to the listing of our shares of Class A common stock, the consummation of this offering or October 21, 2025. In each case, the additional retainer will be paid within 30 days of the triggering event and will be prorated based on the number of days that have elapsed from October 21, 2024 through the date of such event, over 365. Subject to the requisite approvals by the Company and an effective equity incentive plan being in place, if the payment of Mr. Rabun’s additional retainer is triggered by the consummation of this offering, the retainer will be satisfied upon consummation of this offering with a restricted stock unit award that will vest immediately following grant; otherwise, Mr. Rabun’s additional retainer will be paid in cash. No arrangements have been entered into relating to payment of compensation by the Company to members of our board of directors after this offering. In connection with this offering, we expect that our board of directors will establish a compensation package for non-executive members of our board of directors.

Overview

Following this offering and the corporate reorganization, HMH Inc. will be a holding company whose sole material asset will consist of a % equity interest in HMH B.V., with such equity interest consisting of B.V. Voting Class A Shares and B.V. Voting Class B Shares. HMH B.V. will continue to wholly own all of our operating assets. After the consummation of the transactions contemplated by this prospectus, HMH Inc. will own all of the B.V. Voting Shares.

In connection with this offering:

•

HMH B.V. will recapitalize to convert (i) B.V. Voting Class A Shares to B.V. Non-Voting Class A Shares and (ii) B.V. Voting Class B Shares to B.V. Non-Voting Class B Shares;

•

HMH Inc. will issue shares of Class A common stock to purchasers in this offering in exchange for the proceeds of this offering;

•

After giving effect to these transactions and this offering and the application of the net proceeds therefrom and assuming the underwriters do not exercise their option to purchase additional shares of Class A common stock and prior to giving effect to the vesting of any LTI Awards that may vest in connection with this offering and any future redemptions of B.V. Non-Voting Shares (and, if applicable, acquisitions of Mercury HoldCo Inc. shares) pursuant to the Exchange Agreement:

•

181

•

the investors in this offering, collectively, will own all of the shares of our Class A common stock, representing % total voting power of our capital stock; and

•

HMH Inc. will own all of the B.V. Voting Shares, representing a % equity interest in HMH B.V., which will represent 100% total voting power of the equity in HMH B.V.

If the underwriters exercise in full their option to purchase additional shares of Class A common stock in the offering:

•

the investors in this offering, collectively, will own all of the shares of our Class A common stock, representing % total voting power of our capital stock; and

•

HMH Inc. will own all of the B.V. Voting Shares, representing a % equity interest in HMH B.V., which will represent 100% total voting power of the equity in HMH B.V.

Following this offering, under the Exchange Agreement, each Principal Stockholder party thereto will, subject to certain limitations, have the right, pursuant to the Redemption Right, to cause HMH B.V. to acquire or directly cancel all or a portion of its B.V. Non-Voting Shares, together with all or an equal portion of its shares of our Class B common stock, for (i) shares of our Class A common stock at a redemption ratio of one share of Class A common stock for each bundle of one B.V. Non-Voting Class A Share, one B.V. Non-Voting Class B Share and one share of our Class B common stock redeemed, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions, or, upon mutual agreement between such Principal Stockholder and us, (ii) an equivalent amount of cash, based on the trailing ten-day VWAP prior to the redemption date. Alternatively, upon the exercise of the Redemption Right, we (instead of HMH B.V.) will have the right, pursuant to the Call Right, to acquire each tendered bundle of one B.V. Non-Voting Class A Share, one B.V. Non-Voting Class B Share and one share of our Class B common stock directly from such Principal Stockholder for (a) one share of Class A common stock, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions, or, upon mutual agreement between such Principal Stockholder and us, (b) an equivalent amount of cash, based on the trailing ten-day VWAP prior to the redemption date.

182

Under the Exchange Agreement, Akastor will, subject to certain limitations, also have the right, pursuant to the Hybrid Redemption Right (and in lieu of exercising the Redemption Right), to cause HMH Inc. to acquire all or a portion of its B.V. Non-Voting Class B Shares and all or a portion of its Mercury HoldCo Inc. shares, together with all or an equal portion of its shares of our Class B common stock, for (i) shares of our Class A common stock at an exchange ratio of one share of Class A common stock for each bundle of a specified number of Mercury HoldCo Inc. shares (representing indirectly an ownership interest in one B.V. Non-Voting Class A Share), one B.V. Non-Voting Class B Share and one share of our Class B common stock exchanged, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions and adjustments to account for any net assets held by Mercury HoldCo Inc. other than HMH B.V. Non-Voting Class A Shares, or, upon mutual agreement between Akastor and us, (ii) an equivalent amount of cash, based on the trailing ten-day VWAP prior to the exchange date.

In connection with the closing of this offering, we will enter into the Tax Receivable Agreement with the Principal Stockholders. The Tax Receivable Agreement will generally provide for the payment by us to the Principal Stockholders of 85% of the net cash savings, if any, in U.S. federal, state, local and foreign income tax and franchise tax that we actually realize (or are deemed to realize in certain circumstances) in periods after this offering as a result of, as applicable to each Principal Stockholder, (i) certain increases in tax basis that occur as a result of our acquisition (or deemed acquisition for U.S. federal income tax purposes) of all of such Principal Stockholder’s B.V. Voting Shares in connection with this offering or any portion of such Principal Stockholder’s B.V. Non-Voting Shares pursuant to the exercise of the Redemption Right or our Call Right, (ii) the utilization of certain NOLs of Mercury HoldCo Inc. in the event that we acquire Mercury HoldCo Inc. shares pursuant to the exercise of the Hybrid Redemption Right and (iii) imputed interest deemed to be paid by us as a result of, and additional tax basis arising from, any payments we make under the Tax Receivable Agreement. Payments will generally be made under the Tax Receivable Agreement as we realize actual cash tax savings in periods after this offering from the tax benefits covered by the Tax Receivable Agreement. However, if we experience a change of control (as defined in the Tax Receivable Agreement) or the Tax Receivable Agreement terminates early (at our election or as a result of a material breach of our obligations thereunder), we could be required to make a substantial, immediate lump-sum payment in advance of any actual cash tax savings. Because we are a holding company with no independent means of generating revenue, our ability to make payments under the Tax

183

Receivable Agreement is dependent on the ability of HMH B.V. to make distributions to us in an amount sufficient to cover our obligations under the Tax Receivable Agreement.

The following diagram indicates our corporate structure immediately preceding this offering and the transactions related thereto:

Offering

Only Class A common stock will be sold to investors in this offering. Immediately following this offering, there will be shares of our Class A common stock, shares of our Class B common stock, B.V. Voting Class A Shares, B.V. Voting Class B Shares, B.V. Non-Voting Class A Shares and B.V. Non-Voting Class B Shares outstanding.

We estimate that our net proceeds from this offering, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, will be $ million. We intend to (i) use $ million of the net proceeds from this offering to pay the cash consideration portion of the purchase price to purchase an aggregate B.V. Voting Class A Shares and B.V. Voting Class B Shares from Baker Hughes and/or Akastor pursuant to the corporate reorganization (see “Corporate reorganization”) and (ii) contribute all of the remaining net proceeds from this offering to HMH B.V. in exchange for a number of B.V. Voting Class A Shares and B.V. Voting Class B Shares such that the number of B.V. Voting Class A Shares and

185

B.V. Voting Class B Shares, respectively, held by us (taking into account the B.V. Voting Class A Shares and B.V. Voting Class B Shares acquired by us from the Principal Stockholders pursuant to the corporate reorganization) equals the number of shares of Class A common stock sold by us in the offering. HMH B.V. intends to use $ million of the net proceeds received by it to repay all of the outstanding principal and accrued and unpaid interest under the Shareholder Loans from Baker Hughes Holdings LLC and Akastor AS, which totaled $134.6 million as of March 31, 2025, and any remaining amounts for general corporate purposes, which may include funding for acquisitions, working capital requirements, capital expenditures and the repayment, refinancing, redemption or repurchase of indebtedness or other securities. If the underwriters exercise in full their option to purchase additional shares of Class A common stock, we intend to contribute all of the additional net proceeds to HMH B.V. in exchange for an additional B.V. Voting Class A Shares and B.V. Voting Class B Shares. HMH B.V. intends to use such additional net proceeds for general corporate purposes, which may include funding for acquisitions, working capital requirements, capital expenditures and the repayment, refinancing, redemption or repurchase of indebtedness or other securities. See “Use of proceeds.”

After giving effect to the corporate reorganization and this offering and the application of the net proceeds therefrom and assuming the underwriters do not exercise their option to purchase additional shares of Class A common stock and prior to giving effect to the vesting of any LTI Awards that may vest in connection with this offering and any future redemptions of B.V.

Holding company structure

Our post-offering organizational structure will allow the Principal Stockholders to retain their equity ownership in HMH B.V., a partnership for U.S. federal income tax purposes. Investors in this offering will, by contrast, hold their equity ownership in the form of shares of Class A common stock in HMH Inc., and HMH Inc. is classified as a domestic corporation for U.S. federal income tax purposes. The Principal Stockholders and HMH Inc. will generally incur U.S. federal, state and local income taxes on their proportionate share of any taxable income of HMH B.V.’s U.S. and non-U.S. operations, as applicable.

In addition, pursuant to HMH Inc.’s amended and restated certificate of incorporation and the HMH B.V. Partnership Agreement, HMH Inc.’s capital structure and the capital structure of HMH B.V. will generally

186

replicate one another and will provide for customary anti-dilution mechanisms in order to maintain the one-for-one redemption ratio between the B.V. Shares and HMH Inc.’s Class A common stock, among other things.

The holders of B.V. Shares, including HMH Inc., will be allocated their proportionate share of any taxable income or loss of HMH B.V.’s U.S. and non-U.S. operations, as applicable, and will generally incur U.S. federal, state and local income taxes on their proportionate share of any taxable income of HMH B.V.’s U.S. and non-U.S. operations, as applicable. The HMH B.V. Partnership Agreement will provide, to the extent cash is available and to the extent permitted under applicable law, for generally pro rata distributions to the holders of B.V. Shares in an amount generally intended to allow such holders to satisfy their respective income tax liabilities with respect to their allocable share of the income of HMH B.V., based on certain assumptions and conventions, provided that, under applicable tax rules, HMH B.V. is required to allocate net income disproportionately to its shareholders in certain circumstances, and we intend to cause HMH B.V. to make non-pro rata payments to us to reimburse us for our corporate and other overhead expenses.

187

Certain relationships and related party transactions

Exchange Agreement

In connection with this offering, we will enter into the Exchange Agreement with HMH B.V. and certain of the Principal Stockholders. Under the Exchange Agreement, each Principal Stockholder party thereto will, subject to certain limitations, have the right, pursuant to the Redemption Right, to cause HMH B.V. to acquire or directly cancel all or a portion of its B.V. Non-Voting Shares, together with all or an equal portion of its shares of our Class B common stock, for (i) shares of our Class A common stock at a redemption ratio of one share of Class A common stock for each bundle of one B.V. Non-Voting Class A Share, one B.V. Non-Voting Class B Share and one share of our Class B common stock redeemed, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions, or, upon mutual agreement between such Principal Stockholder and us, (ii) an equivalent amount of cash, based on the trailing ten-day VWAP prior to the redemption date. Alternatively, upon the exercise of the Redemption Right, we (instead of HMH B.V.) will have the right, pursuant to the Call Right, to acquire each tendered bundle of one B.V. Non-Voting Class A Share, one B.V. Non-Voting Class B Share and one share of our Class B common stock directly from such Principal Stockholder for (a) one share of Class A common stock, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions, or, upon mutual agreement between such Principal Stockholder and us, (b) an equivalent amount of cash, based on the trailing ten-day VWAP prior to the redemption date.

Our decision to mutually agree with a Principal Stockholder on whether to make a cash payment upon such Principal Stockholder’s election under the Redemption Right or the Hybrid Redemption Right will be made by our independent directors (within the meaning of the Nasdaq listing rules). Such independent directors will make such decision based on facts in existence at the time of the decision, which we expect would include the relative value of the Class A common stock (including trading prices for the Class A common stock at the time), the cash purchase price, the availability of other sources of liquidity (such as an issuance of preferred stock) to acquire or directly cancel the B.V. Non-Voting Shares (and, if applicable, the Mercury HoldCo Inc. shares) and alternative uses for such cash. The parties will agree to treat the exercise of the Redemption Right and the exercise of the Call Right, in each case to the extent permitted under applicable tax law, as purchases by HMH Inc. of interests in HMH B.V. for U.S. federal income tax purposes that give rise to basis adjustments pursuant to Section 743(b) of the Code. Following a period that is 180 days after the date of this prospectus, each Principal Stockholder will be permitted to exercise its Redemption Right, and Akastor will be permitted to exercise its Hybrid Redemption Right, in each case at HMH B.V.’s expense, up to 12 times in any given fiscal year, provided that Akastor will not be permitted to exercise its Redemption Right at any time after it has exercised its Hybrid Redemption Right and each exercise of Akastor’s Hybrid Redemption Right will count as 1.5 redemptions towards its 12 maximum annual exercises of its Redemption Right at HMH B.V.’s expense. Each Principal Stockholder is permitted to exercise its Redemption Right or Hybrid Redemption Right, as applicable, more than 12 times in a given fiscal year, provided that each such exercise in excess of 12 in a given fiscal year will be at the sole expense of such exercising Principal Stockholder. As

188

a Principal Stockholder causes its B.V. Non-Voting Shares (and, if applicable, Mercury HoldCo Inc. shares) to be redeemed pursuant to the Redemption Right or the Hybrid Redemption Right, our direct or indirect equity interest in HMH B.V. will be correspondingly increased, the number of shares of Class A common stock outstanding will be increased and the number of shares of Class B common stock outstanding will be reduced.

The form of Exchange Agreement is filed as an exhibit to the registration statement of which this prospectus forms a part, and the foregoing description of the Exchange Agreement is qualified in its entirety by reference thereto.

HMH B.V. Partnership Agreement

In connection with this offering, HMH B.V., HMH Inc. and certain of the Principal Stockholders will enter into the HMH B.V. Partnership Agreement. The HMH B.V. Partnership Agreement will initially provide for four classes of HMH B.V. Shares entitling the holder to equity of HMH B.V. consisting of (i) B.V. Non-Voting Class A Shares, which track HMH B.V.’s U.S. operations, (ii) B.V. Non-Voting Class B Shares, which track HMH B.V.’s non-U.S. operations, (iii) B.V. Voting Class A Shares, which entitle the holder to one vote and track HMH B.V.’s U.S. operations and (iv) B.V. Voting Class B Shares, which entitle the holder to one vote and track HMH B.V.’s non-U.S. operations. For each pair of one B.V. Non-Voting Class A Share and one B.V. Non-Voting Class B Share, the holder of each pair shall hold one share of HMH Inc. Class B common stock.

Under the HMH B.V. Partnership Agreement, subject to the obligation of HMH B.V. to make tax distributions and to reimburse HMH Inc. for its corporate and other overhead expenses, HMH Inc., as holder of all B.V. Voting Shares, will have the right to determine when distributions will be made to the holders of B.V. Shares and the amount of any such distributions. Following this offering, if HMH Inc. authorizes a distribution, such distribution will be made to the holders of B.V. Shares, including HMH Inc., on a pro rata basis in accordance with their respective percentage ownership of B.V. Shares. Any distributable amount shall be allocated between the B.V. Share classes such that (to the fullest extent permitted by applicable law) distributions on B.V. Non-Voting Class A Shares and B.V. Voting Class A Shares shall be funded by U.S. operations and distributions on B.V. Non-Voting Class B Shares and B.V. Voting Class B Shares shall be funded by non-U.S. operations.

The holders of B.V. Shares, including HMH Inc., will be allocated their proportionate share of any taxable income or loss of HMH B.V.’s U.S. and non-U.S. operations, as applicable, and will generally incur U.S. federal, state and local income taxes on their proportionate share of any net taxable income of HMH B.V.’s U.S. and non-U.S. operations, as applicable. Net profits and net losses of HMH B.V. generally will be allocated to holders of B.V. Shares on a pro rata basis in accordance with their respective percentage ownership of B.V. Shares, except that certain non-pro rata adjustments will be required to be made to reflect built-in gains and losses and tax depletion, depreciation and amortization with respect to such built-in gains and losses. Additionally, for a discussion of the tax attributes created by the corporate reorganization and our entry into the Tax Receivable Agreement in connection with this offering, please see “—Tax Receivable Agreement.”

To the extent HMH B.V. has available cash and subject to the terms of any current and future debt instruments, we intend to cause HMH B.V. to make (i) generally pro rata distributions to its shareholders, including us, in an amount sufficient to allow its shareholders to pay taxes on their allocable share of HMH B.V.’s taxable income from U.S. and non-U.S. operations, as applicable, and to allow us to make payments under the Tax Receivable Agreement we will enter into with the Principal Stockholders in connection with the closing of this offering and (ii) non-pro rata payments to us to reimburse us for our corporate and other overhead expenses. Under applicable tax rules, HMH B.V. is required to allocate net taxable income disproportionately to its shareholders in certain circumstances. The amount of tax distributions will be determined based on an assumed tax rate.

The HMH B.V. Partnership Agreement will provide that, except as otherwise determined by us or in connection with the exercise of HMH Inc.’s Call Right pursuant to the Exchange Agreement, at any time HMH Inc. issues a share of its

189

Class A common stock (including any shares of Class A common stock issued pursuant to any long-term incentive plan, phantom incentive award (including the LTI Awards) or equity award) or any other debt or equity security, the net proceeds, if any, received by HMH Inc. with respect to such issuance shall be concurrently invested in HMH B.V., and HMH B.V. shall issue to HMH Inc. one B.V. Voting Class A Share and one B.V. Voting Class B Share or other economically equivalent debt or equity interest. Conversely, if at any time any shares of HMH Inc.’s Class A common stock are redeemed, repurchased or otherwise acquired, HMH B.V. shall redeem, repurchase or otherwise acquire or directly cancel an equal number of B.V. Voting Class A Shares and B.V. Voting Class B Shares held by HMH Inc., upon the same terms and for the same price, as the shares of HMH Inc.’s Class A common stock that are redeemed, repurchased or otherwise acquired. Furthermore, if at any time any pairs of one B.V. Non-Voting Class A Share and one B.V. Non-Voting Class B Share are transferred to another person, such redemption or transfer of any pairs of B.V. Non-Voting Shares shall include redemption or transfer of the equivalent number of HMH Inc. Class B common stock.

We intend to limit the number of shareholders of HMH B.V., and the HMH B.V. Partnership Agreement will provide for limitations on the ability of the HMH B.V. shareholders to transfer their B.V. Shares and will provide us, as owner of all B.V. Voting Shares, with the right to impose restrictions (in addition to those already in place) on the ability of shareholders of B.V. Non-Voting Shares to cause HMH B.V. to acquire or directly cancel their B.V. Non-Voting Shares pursuant to the Redemption Right to the extent we believe it is necessary to ensure that HMH B.V. will continue to be treated as a partnership for U.S. federal income tax purposes.

Under the HMH B.V. Partnership Agreement, the shareholders of HMH B.V. have agreed that the Principal Stockholders and their affiliates will be permitted to engage in business activities in which we engage or propose to engage, do business with any client of ours and otherwise compete, directly or indirectly, with us.

HMH B.V. will be dissolved only upon the first to occur of (i) the sale of substantially all of its assets and (ii) an election by us to dissolve HMH B.V. Upon dissolution, and following the payment of expenses of liquidation and allocation of profits and losses, HMH B.V. will be liquidated and the proceeds from any liquidation will be applied and distributed in the following manner: (i) first, to creditors (including to the extent permitted by law, creditors who are shareholders of HMH B.V.) in satisfaction of the liabilities of HMH B.V. in the order of priority as provided by law, except any obligations to HMH B.V.’s shareholders in respect of their capital accounts, (ii) second, to establish cash reserves that HMH Inc. reasonably deems necessary for contingent or unforeseen liabilities or future payments and (iii) third, to the shareholders of HMH B.V. in proportion to the number of B.V. Shares owned by each of them.

The form of HMH B.V. Partnership Agreement is filed as an exhibit to the registration statement of which this prospectus forms a part, and the foregoing description of the HMH B.V. Partnership Agreement is qualified in its entirety by reference thereto.

Tax Receivable Agreement

In connection with the closing of this offering, we will enter into the Tax Receivable Agreement with the Principal Stockholders. As described in “Corporate reorganization,” HMH Inc. will acquire B.V. Voting Class A Shares and B.V. Voting Class B Shares from the Principal Stockholders in connection with this offering in exchange for $ in cash and shares of our Class B common stock. In addition, each Principal Stockholder may cause us to acquire or directly cancel all or a portion of its B.V. Non-Voting Shares (or, in the case of Akastor, all or a portion of its B.V. Non-Voting Class B Shares and all or a portion of its Mercury HoldCo Inc. shares), together with all or an equal portion of its shares of our Class B common stock, for shares of Class A common stock in the future pursuant to the Redemption Right, the Call Right or the Hybrid Redemption Right. HMH B.V. intends to make for itself (and for each of its direct or indirect subsidiaries that is treated as a partnership for U.S. federal income tax purposes and that it controls) an election under Section 754 of the Code that will be effective for the taxable year of this offering and each taxable year in which a

190

redemption of B.V. Non-Voting Shares pursuant to the Redemption Right or the Call Right occurs. Pursuant to the Section 754 election, our acquisition (or deemed acquisition for U.S. federal income tax purposes) of B.V. Voting Shares for cash as a part of the corporate reorganization and acquisitions of B.V. Non-Voting Shares pursuant to the Redemption Right or the Call Right is expected to create basis adjustments with respect to our allocable share of the assets of HMH B.V. that would not have been available to us absent our acquisition or deemed acquisition of B.V. Shares as part of the corporate reorganization or pursuant to the exercise of the Redemption Right or the Call Right. The anticipated basis adjustments are expected to increase (for tax purposes) HMH Inc.’s depreciation, depletion and amortization deductions and may also decrease HMH Inc.’s gains (or increase its losses) on future dispositions of certain assets to the extent tax basis is allocated to those assets. Such increased deductions and losses and reduced gains may reduce the amount of cash tax that HMH Inc. would otherwise be required to pay in the future. If Akastor exercises the Hybrid Redemption Right, then we will acquire Mercury HoldCo Inc. shares and, as a result, we will directly or indirectly benefit from any NOLs of Mercury HoldCo Inc. (subject to any limitations under applicable tax law, including Section 382). The anticipated NOLs are expected to reduce the amount of cash tax that Mercury HoldCo Inc. (or, in certain circumstances, HMH Inc.) would otherwise be required to pay in the future in the absence of such NOLs.

The Tax Receivable Agreement will generally provide for the payment by us to the Principal Stockholders of 85% of the net cash savings, if any, in U.S. federal, state, local and foreign income tax and franchise tax that we actually realize (or are deemed to realize in certain circumstances) in periods after this offering as a result of, as applicable to each Principal Stockholder, (i) certain increases in tax basis that occur as a result of our acquisition (or deemed acquisition for U.S. federal income tax purposes) of all of such Principal Stockholder’s B.V. Voting Shares in connection with this offering or any portion of such Principal Stockholder’s B.V. Non-Voting Shares pursuant to the exercise of the Redemption Right or our Call Right, (ii) the utilization of certain NOLs of Mercury HoldCo Inc. in the event that we acquire Mercury HoldCo Inc. shares pursuant to the exercise of the Hybrid Redemption Right and (iii) imputed interest deemed to be paid by us as a result of, and additional tax basis arising from, any payments we make under the Tax Receivable Agreement. Under the Tax Receivable Agreement, we will retain the benefit of the remaining 15% of these cash savings. The rights of the Principal Stockholders to receive payment under the Tax Receivable Agreement are not assignable, except for assignments to such Principal Stockholder’s affiliates or in connection with the assignment of B.V. Non-Voting Shares in accordance with the HMH B.V. Partnership Agreement.

The payment obligations under the Tax Receivable Agreement are HMH Inc.’s obligations and not obligations of HMH B.V., and we expect that the payments we will be required to make under the Tax Receivable Agreement will be substantial. Estimating the amount and timing of payments that may become due under the Tax Receivable Agreement is by its nature imprecise. For purposes of the Tax Receivable Agreement, cash savings in tax generally will be calculated by comparing HMH Inc.’s actual tax liability (determined by using the actual applicable U.S. federal, state, local and foreign income tax rates and franchise tax rates) to the amount it would have been required to pay had it not been able to utilize any of the tax benefits subject to the Tax Receivable Agreement. The amounts payable, as well as the timing of any payments, under the Tax Receivable Agreement are dependent upon significant future events and assumptions, including the timing of the redemptions of B.V. Non-Voting Shares (and, if applicable, acquisitions of Mercury HoldCo Inc. shares), the price of our Class A common stock at the time of each redemption or acquisition, the extent to which such redemptions are taxable transactions, the amount of each Principal Stockholder’s tax basis in its B.V. Non-Voting Shares at the time of the relevant redemption, the depreciation and amortization periods that apply to the increase in tax basis, the utilization of certain NOL carryovers (in the event we acquire Mercury Holdco Inc. shares), the amount and timing of the utilization of tax attributes, the amount and timing of taxable income we generate in the future, the U.S. federal, state, local and foreign income tax rates and franchise tax rates then applicable and the portion of HMH Inc.’s payments under the Tax Receivable Agreement that constitute imputed interest or give rise to depreciable or amortizable tax basis.

191

We expect that if the Tax Receivable Agreement were terminated immediately after this offering (assuming an initial public offering price of $ per share of Class A common stock (the midpoint of the price range set forth on the cover page of this prospectus)), the estimated termination payments would be approximately $ million (calculated using a discount rate equal to the greater of (i) SOFR plus 100 basis points or (ii) 5%, applied against an undiscounted liability of approximately $ million based on a 21% U.S. federal corporate income tax rate under the Tax Cuts and Jobs Act of 2017, and applicable state and local income tax rates).

A delay in the timing of redemptions of B.V. Shares (and, if applicable, acquisitions of Mercury HoldCo Inc. shares), holding other assumptions constant, would be expected to decrease the discounted value of the amounts payable under the Tax Receivable Agreement as the benefit of the depreciation and amortization deductions would be delayed and the estimated increase in tax basis could be reduced if allocations of HMH B.V. taxable income exceed distributions and allocations of losses to the redeeming shareholder prior to the redemption. Stock price increases or decreases at the time of each redemption of B.V. Shares would be expected to result in a corresponding increase or decrease in the undiscounted amounts payable under the Tax Receivable Agreement in an amount equal to % of the tax-effected change in price. The amounts payable under the Tax Receivable Agreement are dependent upon HMH Inc. having sufficient future taxable income to utilize the tax benefits on which it is required to make payments under the Tax Receivable Agreement. If HMH Inc.’s projected taxable income is significantly reduced, the expected payments would be reduced to the extent such tax benefits do not result in a reduction of HMH Inc.’s future income tax liabilities.

The foregoing amounts are merely estimates, and the actual payments could differ materially. It is possible that future transactions or events could increase or decrease the actual tax benefits realized and the Tax Receivable Agreement payments as compared to the foregoing estimates. Moreover, there may be a negative impact on our liquidity if, as a result of timing discrepancies or otherwise, (i) the payments under the Tax Receivable Agreement exceed the actual benefits we realize in respect of the tax attributes subject to the Tax Receivable Agreement or (ii) distributions to HMH Inc. by HMH B.V. are not sufficient to permit HMH Inc. to make payments under the Tax Receivable Agreement after it has paid its taxes and other obligations. See “Risk factors—Risks related to this offering and ownership of our Class A common stock—In certain cases, payments under the Tax Receivable Agreement may be accelerated and significantly exceed the actual benefits, if any, we realize in respect of the tax attributes subject to the Tax Receivable Agreement.”

In addition, although we are not aware of any issue that would cause the IRS or other relevant tax authorities to challenge potential tax basis increases or other tax benefits covered under the Tax Receivable Agreement, the Principal Stockholders will not reimburse us for any payments previously made under the Tax Receivable Agreement if such basis increases or other tax benefits that have given rise to payments under the Tax Receivable Agreement are subsequently disallowed, except that excess payments made to the Principal Stockholders will be netted against payments that would otherwise be made to the Principal Stockholders, if any, after our determination of such excess. As a result, in such circumstances, HMH Inc. could make payments that are greater than its actual cash tax savings, if any, and may not be able to recoup those payments, which could adversely affect its liquidity. See “Risk factors—Risks related to this offering and ownership of our Class A common stock—We will not be reimbursed for any payments made under the Tax Receivable Agreement in the event that any tax benefits are subsequently disallowed.”

The term of the Tax Receivable Agreement will commence upon the completion of this offering and will continue until all tax benefits that are subject to the Tax Receivable Agreement have been utilized or expired, unless we exercise our right to terminate the Tax Receivable Agreement (or the Tax Receivable Agreement is terminated due to other circumstances, including our breach of a material obligation thereunder or certain mergers or other changes of control), and we make the termination payment specified in the Tax Receivable Agreement. In the event that the Tax Receivable Agreement is not terminated, the payments under the Tax

192

Receivable Agreement are anticipated to continue for 16 years after the date of the last redemption of the B.V. Non-Voting Shares. Accordingly, it is expected that payments will continue to be made under the Tax Receivable Agreement for more than 16 years. Payments will generally be made under the Tax Receivable Agreement as we realize actual cash tax savings in periods after this offering from the tax benefits covered by the Tax Receivable Agreement. However, if we experience a change of control (as defined in the Tax Receivable Agreement) or the Tax Receivable Agreement terminates early (at our election or as a result of a material breach of our obligations thereunder), we could be required to make a substantial, immediate lump-sum payment in advance of any actual cash tax savings. This payment would equal the present value of hypothetical future payments that could be required to be paid under the Tax Receivable Agreement (determined by applying a discount rate equal to the greater of (i) SOFR plus 100 basis points or (ii) 5%). The calculation of hypothetical future payments will be based upon certain assumptions and deemed events set forth in the Tax Receivable Agreement. Any early termination payment may be made significantly in advance of, and may materially exceed, the actual realization, if any, of the future tax benefits to which the termination payment relates.

The Tax Receivable Agreement will provide that, in the event of a material breach by us, which includes, but is not limited to, (i) our failure to make a payment under the Tax Receivable Agreement within 45 business days after such payment is due (except to the extent such payment is prohibited by applicable law or we do not have and cannot take commercially reasonable actions to obtain sufficient funds to make such payment) or (ii) our breach of any material obligation under the Tax Receivable Agreement by operation of law as a result of the rejection of the Tax Receivable Agreement in a case commenced under the Bankruptcy Code, then the Principal Stockholders may elect to treat such breach as an early termination, which would cause all our payment and other obligations under the Tax Receivable Agreement to be accelerated and become due and payable applying the same assumptions described above.

As a result of either an early termination (at our election or as a result of a material breach of our obligations under the Tax Receivable Agreement) or a change of control, we could be required to make payments under the Tax Receivable Agreement that exceed our actual cash tax savings under the Tax Receivable Agreement. In these situations, our obligations under the Tax Receivable Agreement could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales or other forms of business combinations or changes of control. There can be no assurance that we will be able to finance our obligations under the Tax Receivable Agreement.

Decisions we make in the course of running our business, such as with respect to mergers, asset sales, other forms of business combinations or other changes in control, may influence the timing and amount of payments that are received by the Principal Stockholders under the Tax Receivable Agreement. For example, the earlier disposition of assets following a redemption of B.V. Shares may accelerate payments under the Tax Receivable Agreement and increase the present value of such payments, and the disposition of assets before a redemption of B.V. Shares may increase the Principal Stockholders’ tax liability without giving rise to any rights of the Principal Stockholders to receive payments under the Tax Receivable Agreement. Such effects may result in differences or conflicts of interest between the interests of the Principal Stockholders and other stockholders.

Payments under the Tax Receivable Agreement are generally due within a specified period of time following the filing of our tax return for the taxable year with respect to which the payment obligation arises, but interest on such payments will begin to accrue at a rate of SOFR plus 100 basis points from the due date (without extensions) of such tax return. Late payments will generally accrue interest at a rate of SOFR plus 500 basis points.

Because we are a holding company with no independent means of generating revenue, our ability to make payments under the Tax Receivable Agreement is dependent on the ability of HMH B.V. to make distributions to us in an amount sufficient to cover our obligations under the Tax Receivable Agreement. This ability, in turn, may depend on the ability of HMH B.V.’s subsidiaries to make distributions to it. The ability of HMH B.V., its

193

subsidiaries and other entities in which it directly or indirectly holds an equity interest to make such distributions will be subject to, among other things, (i) the applicable provisions of Dutch law (or other applicable jurisdiction) that may limit the amount of funds available for distribution and (ii) restrictions in relevant debt instruments issued by HMH B.V. or its subsidiaries and other entities in which it directly or indirectly holds an equity interest.

The form of Tax Receivable Agreement is filed as an exhibit to the registration statement of which this prospectus forms a part, and the foregoing description of the Tax Receivable Agreement is qualified in its entirety by reference thereto.

Registration Rights Agreement

In connection with the closing of this offering, we plan to enter into a registration rights agreement with affiliates of Baker Hughes and Akastor (the “Registration Rights Agreement”). We expect that the Registration Rights Agreement will contain provisions by which we agree to register under the federal securities laws the offer and resale of shares of our Class A common stock by affiliates of Baker Hughes and Akastor or permitted transferees, as more fully described below.

The Registration Rights Agreement will include provisions by which we agree that, at any time after the 180-day lock-up period, as described in “Underwriting,” and subject to certain limitations, each of Baker Hughes and Akastor will have the right to require us to prepare and file a registration statement registering the offer and sale of their shares of our Class A common stock. Generally, we will be required to provide notice of the request to certain other holders of our Class A common stock who may, in certain circumstances, participate in the registration. Subject to certain exceptions, each of Baker Hughes and Akastor will be entitled to make three demands per calendar year that we register such securities.

In addition, each of Baker Hughes and Akastor (together with any person to whom rights under the Registration Rights Agreement are assigned in accordance therewith, the “RRA Holders”) will have certain “piggy-back” registration rights in the event that we propose to file a registration statement with respect to an offering of our equity securities for our own account or for the account of our stockholders pursuant to which we would be required to notify the RRA Holders and allow them to register for sale a number of their registrable securities as they may request in writing, subject to certain exceptions. Furthermore, not later than 180 days after the date the Registration Rights Agreement is executed, we will be required to prepare and file with the SEC a shelf registration statement on Form S-3 (or, if Form S-3 is not available to be used by us at such time, on Form S-1 or another appropriate form permitting the registration of such registrable securities for resale) to permit the public resale of all of the registrable securities thereunder in accordance with the terms of the Registration Rights Agreement.

We will not be obligated to effect a demand registration or an underwritten offering within 90 days after any other demand registration and will not be obligated to effect an underwritten offering pursuant to a resale shelf registration statement within 90 days after any other underwritten offering pursuant to a resale shelf registration statement, subject to certain requirements.

The Registration Rights Agreement will also generally obligate us to cooperate reasonably with and take such customary actions as may be reasonably requested by the RRA Holders in connection with the registration of registrable securities.

These registration rights will be subject to certain conditions and limitations, and we will generally be obligated to pay all registration expenses in connection with these registration obligations, regardless of whether a registration statement is filed or becomes effective. The Registration Rights Agreement will also require us to indemnify the RRA Holders against certain liabilities under the Securities Act.

194

Stockholders’ Agreement

HMH B.V. is party to a shareholders’ agreement, dated as of October 1, 2021, as amended February 8, 2024 (the “Existing Shareholders’ Agreement”), with Baker Hughes Holdings LLC, Akastor ASA, Akastor AS and Mercury HoldCo Inc. In connection with the closing of this offering, the Existing Shareholders’ Agreement will be terminated and we will enter into a new stockholders’ agreement (the “Stockholders’ Agreement”) with the Principal Stockholders. Among other things, the Stockholders’ Agreement will provide each of the Principal Stockholders with the right to designate nominees to our board of directors as follows:

•

so long as Baker Hughes and its affiliates collectively beneficially own at least shares of our common stock, Baker Hughes can designate two nominees to our board of directors;

•

so long as Baker Hughes and its affiliates collectively beneficially own at least but less than shares of our common stock, Baker Hughes can designate one nominee to our board of directors;

•

so long as Akastor and its affiliates collectively beneficially own at least shares of our common stock, Akastor can designate two nominees to our board of directors; and

•

so long as Akastor and its affiliates collectively beneficially own at least but less than shares of our common stock, Akastor can designate one nominee to our board of directors.

In addition, if we establish any committee of our board of directors other than the audit committee, the compensation committee or the nominating and governance committee, such committee will consist of at least one director nominated by each Principal Stockholder if requested by such Principal Stockholder and only if such Principal Stockholder is then entitled to nominate at least one director to our board of directors.

The Stockholders’ Agreement will also provide each Principal Stockholder with certain information rights.

The form of Stockholders’ Agreement is filed as an exhibit to the registration statement of which this prospectus forms a part, and the foregoing description of the Stockholders’ Agreement is qualified in its entirety by reference thereto.

Indemnification agreements

195

that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. We believe that the limitation of liability provision in our amended and restated certificate of incorporation and the indemnification agreements will facilitate our ability to continue to attract and retain qualified individuals to serve as directors and officers.

Shareholder Loans

On October 1, 2021, HMH B.V. entered into the Shareholder Loan Agreement with Baker Hughes Holdings LLC and Akastor AS to finance its operating and finance activities. Baker Hughes Holdings LLC provided the $80.0 million Baker Hughes Shareholder Loan under the Shareholder Loan Agreement, and Akastor AS provided the $20.0 million Akastor Shareholder Loan under the Shareholder Loan Agreement. The Shareholder Loans mature on the earliest to occur of October 1, 2026 or a liquidation event (as defined in the Shareholder Loan Agreement) such as the consummation of this offering. As of March 31, 2025, the total amount of principal and accrued and unpaid interest outstanding under the Shareholder Loans was $134.6 million, which included $105.9 million outstanding under the Baker Hughes Shareholder Loan and $28.7 million outstanding under the Akastor Shareholder Loan. HMH B.V. also agreed to pay Baker Hughes and Akastor for certain deferred tax assets related to the contributed businesses in the amounts of approximately $0.3 million and $2.2 million, respectively, with such payment made by way of an increase to the Shareholder Loans. Such additional amounts relating to deferred tax assets are reflected in the Shareholder Loans’ balances as of March 31, 2025. The Shareholder Loans bear interest at a rate of 8.0% per annum. The Shareholder Loans are unsecured. The Shareholder Loan Agreement includes certain restrictive covenants that may limit our ability to, among other things, incur additional indebtedness or make or declare dividends. The Shareholder Loan Agreement contains customary representations and warranties, affirmative covenants and events of default. If an event of default exists under the Shareholder Loan Agreement, the lenders will be able to accelerate the maturity of the Shareholder Loans and exercise other rights and remedies. Subject to certain notice requirements, HMH B.V. may voluntarily prepay outstanding loans under the Shareholder Loan Agreement in whole or in part without premium or penalty.

Shareholder Note

On March 17, 2023, HMH B.V. entered into a note with Baker Hughes Holdings LLC and Akastor AS (as amended, the “Shareholder Note”) whereby HMH B.V. extended credit in the principal amount of $3.45 million to Baker Hughes Holdings LLC and $3.49 million to Akastor AS. The Shareholder Note matures on the earliest to occur of October 1, 2026 or a liquidation event (as defined in the Shareholder Loan Agreement) such as the consummation of this offering and accrues interest at a rate of 8.0% per annum. Subject to certain notice requirements, Baker Hughes Holdings LLC and Akastor AS may voluntarily prepay the Shareholder Note in whole or in part without premium or penalty. There is no right of set-off against the Shareholder Loans.

(“Step Oiltools”), would be made on a delayed basis until certain Russian regulatory approvals were obtained. Subsequently, Step Oiltools’ business activities were significantly impacted by the Russian invasion of Ukraine, and it was decided that Step Oiltools would be liquidated. The parties agreed to cease seeking regulatory approval for the sale and to settle a seller’s credit in the amount of approximately $16.0 million, payable by Akastor to HMH B.V., in exchange for Akastor transferring to HMH B.V. the proceeds from the Step Oiltools liquidation. HMH B.V.’s management has assessed the expected net proceeds from the liquidation of Step Oiltools during 2022 and does not believe that such proceeds would yield net cash flows equal to the original seller’s credit receivable from Akastor and, as such, recorded a one-time charge of $16.0 million in 2022. The fair value of the receivable has been remeasured to zero as of December 31, 2024 and 2023.

Payment of pension benefits

Pursuant to the JV Transaction Agreement, as part of its contribution to HMH B.V. at the time of HMH B.V.’s formation, Akastor agreed to pay certain carved-out pension liabilities existing in MHWirth AS prior to its contribution to HMH B.V. until such time as Akastor owns less than 5% of HMH B.V.’s equity interests, at which time Akastor will be obligated to pay all estimated remaining and unpaid pension costs. HMH B.V. estimated the value of such remaining and unpaid pension costs to be $18.5 million and $20.2 million as of December 31, 2024 and 2023, respectively, and HMH B.V. recorded a receivable of $19.9 million and $21.9 million as of December 31, 2024 and 2023, respectively, related to such pension payments from Akastor, which is reduced in line with pension payments to former employees in 2024 and 2023. The difference between unpaid pension costs and receivable is due to the timing of payments made to pensioners and pension payments received from Akastor by HMH B.V.

Financial guarantees

As of March 31, 2025, Akastor had issued financial guarantees of approximately $4.8 million in favor of MHWirth AS, a wholly owned subsidiary of HMH B.V., for fulfillment of performance under certain operational support frame agreements.

Transition services agreement

On October 1, 2021, in connection with the formation of HMH B.V., HMH B.V. entered into a transition services agreement with Akastor pursuant to which, in exchange for an hourly fee, Akastor would provide HMH B.V. with certain transitional finance, IT and treasury services for a term that concluded at the end of 2023. HMH B.V. paid a total of $0.4 million to Akastor for the services provided under the transition services agreement. All services under the transition services agreement have now been performed, and there are no outstanding obligations for either party thereunder.

Policies and procedures for review of related party transactions

A “related party transaction” is a transaction, arrangement or relationship in which we or any of our subsidiaries were, are or will be a participant, the amount of which involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest. A “related person” means:

•

any person who is, or at any time during the applicable period was, one of our executive officers or one of our directors;

198

•

any person who is known by us to be the beneficial owner of more than 5.0% of our Class A common stock;

•

any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of a director, executive officer or a beneficial owner of more than 5.0% of our Class A common stock, and any person (other than a tenant or employee) sharing the household of such director, executive officer or beneficial owner of more than 5.0% of our Class A common stock; and

•

any firm, corporation or other entity in which any of the foregoing persons is a partner or principal or in a similar position or in which such person has a 10.0% or greater beneficial ownership interest.

In connection with this offering and subject to the rules of Nasdaq, we will establish an audit committee consisting solely of independent directors whose functions will be set forth in the audit committee charter. We anticipate that one of the audit committee’s functions will be to review and approve all relationships and transactions involving us and any related person. Our board of directors will adopt a written policy prior to the completion of this offering that will provide that our audit committee or, in certain cases, the disinterested members of our board of directors will review all transactions with related persons that are required to be disclosed under SEC rules and, when appropriate, initially authorize or ratify all such transactions. Any director who is a related person with respect to a transaction under review will not be permitted to participate in any discussion or approval of such transaction.

Such written policy will provide that, in determining whether or not to recommend the initial approval or ratification of a transaction with a related person, our audit committee or, if applicable, the disinterested members of our board of directors should consider all of the relevant facts and circumstances available.

Such written policy will be adopted in connection with this offering and, therefore, the transactions described above were not reviewed under such policy.

Class A common stock

Voting Rights. Holders of shares of our Class A common stock are entitled to one vote per share held of record on all matters to be voted upon by the stockholders. Holders of shares of our Class A common stock and Class B common stock vote together as a single class on all matters presented to our stockholders for their vote or approval, except with respect to the amendment of certain provisions of our amended and restated certificate of incorporation that would alter or change the powers, preferences or special rights of the Class B common stock so as to affect them adversely, which amendments must be approved by a majority of the votes entitled to be cast by the holders of the shares affected by the amendment, voting as a separate class, or as otherwise required by applicable law. The affirmative vote of the holders of a majority of our outstanding Class A common stock and Class B common stock, voting separately, is required to approve any disparate treatment with respect to dividends or the subdivision, combination or reclassification of either our Class A common stock or Class B common stock. Holders of our Class A common stock are not entitled to vote with respect to the amendment of certain provisions relating solely to outstanding series of preferred stock where the holders thereof are entitled to vote. Holders of our Class A common stock do not have cumulative voting rights.

Dividend Rights.

Class B common stock

Generally. In connection with the corporate reorganization and this offering, each Principal Stockholder will receive one share of Class B common stock for each bundle of one B.V. Non-Voting Class A Share and one B.V. Non-Voting Class B Share that it holds. Shares of Class B common stock will not be transferrable except in connection with a permitted transfer of a corresponding number of bundles of one B.V. Non-Voting Class A Share and one B.V. Non-Voting Class B Share. Accordingly, each Principal Stockholder will have a number of votes in HMH Inc. equal to the number of bundles of one B.V. Non-Voting Class A Share and one B.V. Non-Voting Class B Share that it holds.

Voting Rights. Holders of shares of our Class B common stock are entitled to one vote per share held of record on all matters to be voted upon by the stockholders. Holders of shares of our Class A common stock and Class B common stock vote together as a single class on all matters presented to our stockholders for their vote or approval, except with respect to the amendment of certain provisions of our amended and restated certificate of incorporation that would alter or change the powers, preferences or special rights of the Class B common stock so as to affect them adversely, which amendments must be approved by a majority of the votes entitled to be cast by the holders of the shares affected by the amendment, voting as a separate class, or as otherwise required by applicable law. The affirmative vote of the holders of a majority of our outstanding Class A common stock and Class B common stock, voting separately, is required to approve any disparate treatment with respect to dividends or the subdivision, combination or reclassification of either our Class A common stock or Class B common stock. Holders of our Class B common stock are not entitled to vote with respect to the amendment of certain provisions relating solely to outstanding series of preferred stock where the holders thereof are entitled to vote. Holders of our Class B common stock do not have cumulative voting rights.

Dividend Rights. Holders of our Class B common stock do not have any right to receive dividends, unless the dividend consists of shares of our Class B common stock or of rights, options, warrants or other securities convertible or exercisable into or exchangeable or redeemable for shares of Class B common stock paid proportionally with respect to each outstanding share of our Class B common stock.

Number of Authorized Shares. The number of authorized shares of our Class B common stock may be increased or decreased (but not below the number of shares thereof then outstanding or reserved) by the affirmative vote of the holders of a majority in voting power of our stock entitled to vote thereon without a separate class vote of the holders of our preferred stock (if any), Class A common stock or Class B common stock, irrespective of the provisions of Section 242(b)(2) of the DGCL.

Liquidation Rights. Holders of our Class B common stock do not have any right to receive a distribution upon a liquidation or winding up of HMH Inc.

Preferred stock

Our amended and restated certificate of incorporation will authorize our board of directors, subject to any limitations prescribed by law, without further stockholder approval, to establish and to issue from time to time one or more classes or series of preferred stock, covering up to an aggregate of 10,000,000 shares of preferred stock. Each class or series of preferred stock will cover the number of shares and will have the powers, preferences, privileges, rights, qualifications, limitations and restrictions determined by our board of directors, which may include, among others, dividend rights, liquidation preferences, voting rights, conversion rights, preemptive rights and redemption rights. The number of authorized shares of our preferred stock may be increased or decreased (but not below the number of shares thereof then outstanding or reserved) by the affirmative vote of the holders of a majority in voting power of our stock entitled to vote thereon without a separate class vote of the holders of our preferred stock (if any), Class A common stock or Class B common

201

stock, irrespective of the provisions of Section 242(b)(2) of the DGCL. Except as provided by law or in a preferred stock designation, the holders of preferred stock will not be entitled to vote at or receive notice of any meeting of stockholders.

Anti-takeover provisions

Certain provisions of the DGCL, our amended and restated certificate of incorporation and our amended and restated bylaws may have an anti-takeover effect and may delay, defer or prevent a merger, acquisition, tender offer, takeover attempt or other change of control transaction or other attempts to influence or replace our incumbent directors and officers.

These provisions will, among other things:

•

Establish advance notice procedures regarding stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of the stockholders. These procedures provide that notice of stockholder proposals must be timely given in writing to our Corporate Secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the annual meeting for the preceding year. Our amended and restated bylaws will specify the requirements as to form and content of all stockholders’ notices. These requirements may preclude stockholders from bringing matters before the stockholders at an annual or special meeting.

•

Provide our board of directors the ability to authorize undesignated preferred stock. This ability makes it possible for our board of directors to issue, without stockholder approval, preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of the Company. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of the Company.

•

Provide that subject to the rights of the holders of any series of preferred stock to elect directors under specified circumstances and the affirmative vote of any Principal Stockholder entitled to nominate at least one director under the amended and restated certificate of incorporation and the terms of the Stockholders’ Agreement, the authorized number of directors may be changed only by resolution of the board of directors.

•

Provide that all vacancies, including newly created directorships, may, except as otherwise required by law or, if applicable, the rights of holders of a series of preferred stock, and subject to the right of a Principal Stockholder to fill a vacancy created by such Principal Stockholder’s nominee under the amended and restated certificate of incorporation and the terms of the Stockholders’ Agreement, be filled by the affirmative vote of a majority of directors then in office, even if such directors constitute less than a quorum.

•

Provide that our amended and restated bylaws can be amended or repealed at any regular or special meeting of stockholders or by our board of directors; provided that any amendment by the stockholders that relates to the size of our board of directors will require the affirmative vote of each Principal Stockholder who is then entitled to designate for nomination at least one director.

•

Provide that, once the Principal Stockholders are no longer entitled to nominate at least three directors to our board of directors pursuant to the amended and restated certificate of incorporation and the terms of the Stockholders’ Agreement, any action required or permitted to be taken by the stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by any consent in writing in lieu of a meeting of such stockholders, subject to the rights of the holders of any series of preferred stock with respect to such series.

202

•

Provide that certain provisions of our amended and restated certificate of incorporation and our amended and restated bylaws may be amended by the affirmative vote of the holders of at least two-thirds of then-outstanding common stock, with the remaining provisions of our amended and restated certificate of incorporation able to be amended by the affirmative vote of the holders of a majority of the then-outstanding common stock.

•

Provide that special meetings of our stockholders may only be called by our board of directors (pursuant to a resolution adopted by a majority of our board of directors), our Chief Executive Officer or the chairman of our board of directors.

Limitation of liability and indemnification matters

Our amended and restated certificate of incorporation will limit the personal liability of our directors and officers to us or our stockholders for monetary damages for breach of their fiduciary duty as directors and officers, except for the following liabilities that cannot be eliminated or limited under the DGCL:

•

for any breach of their 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;

•

with respect to directors, for unlawful payments of dividends or unlawful stock purchases or redemptions, as provided under Section 174 of the DGCL;

•

for any transaction from which the director or officer derived an improper personal benefit; or

•

with respect to officers, in any action by or in the right of the Company.

Any amendment or repeal of these provisions will be prospective only and would not affect any limitation on liability of a director or officer for acts or omissions that occurred prior to any such amendment or repeal.

Our amended and restated certificate of incorporation and our amended and restated bylaws will also provide that we will indemnify our directors and officers to the fullest extent permitted by Delaware law. Our amended and restated bylaws will explicitly authorize us to purchase insurance to protect any of our officers, directors, employees, agents or other entities for any expense, liability or loss, regardless of whether Delaware law would permit indemnification.

We expect to enter into indemnification agreements with each of our directors and officers. These agreements will require us to indemnify these individuals to the fullest extent permitted under Delaware law against liability that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. We believe that the limitation of liability provision in our amended and restated certificate of incorporation and the indemnification agreements will facilitate our ability to continue to attract and retain qualified individuals to serve as directors and officers.

Removal of directors

Subject to the rights of any holders of preferred stock, stockholders holding a majority in voting power of our outstanding equity interests then-entitled to vote at an election of directors may remove any director from office with or without cause.

Corporate opportunities

Subject to the limitations of applicable law, our amended and restated certificate of incorporation will, among other things, contain provisions relating to the duties of any affiliate of Baker Hughes or Akastor who is also

203

one of our officers or directors that becomes aware of a potential business opportunity, transaction or other matter (other than one expressly offered to that director or officer solely in his or her capacity as our director or officer).

Registration rights

For a description of registration rights with respect to our Class A common stock, see “Certain relationships and related party transactions—Registration Rights Agreement.”

Dissenters’ rights of appraisal and payment

Under the DGCL, with certain exceptions, our stockholders will have appraisal rights in connection with a merger or consolidation. Pursuant to the DGCL, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.

Stockholders’ derivative actions

Under the DGCL, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholder’s stock thereafter devolved by operation of law.

Transfer agent and registrar

The transfer agent and registrar for our Class A common stock is Equiniti Trust Company, LLC.

Listing

We have applied to list our Class A common stock on Nasdaq under the symbol “HMH.”

204

Shares eligible for future sale

Prior to this offering, there has been no public market for our Class A common stock. Future sales of our Class A common stock in the public market, or the availability of such shares for sale in the public market, could adversely affect the market price of our Class A common stock prevailing from time to time. As described below, only a limited number of shares will be available for sale shortly after this offering due to contractual and legal restrictions on resale. Nevertheless, sales of a substantial number of shares of our Class A common stock in the public market after such restrictions lapse, or the perception that those sales may occur, could adversely affect the prevailing market price of our Class A common stock at such time and our ability to raise equity-related capital at a time and price we deem appropriate.

Sales of restricted shares

Upon the closing of this offering and after giving effect to the corporate reorganization, we will have outstanding an aggregate of shares of Class A common stock (or shares of Class A common stock if the underwriters exercise in full their option to purchase additional shares of Class A common stock). Of these shares, all of the shares of Class A common stock (or shares of Class A common stock if the underwriters exercise in full their option to purchase additional shares of Class A common stock) to be sold in this offering will be freely tradable without restriction or further registration under the Securities Act, unless the shares are held by any of our “affiliates” as such term is defined in Rule 144. In addition, under the Exchange Agreement, each Principal Stockholder party thereto will, subject to certain limitations, have the right, pursuant to the Redemption Right, to cause HMH B.V. to acquire or directly cancel all or a portion of its B.V. Non-Voting Shares, together with all or an equal portion of its shares of our Class B common stock, for (i) shares of our Class A common stock at a redemption ratio of one share of Class A common stock for each bundle of one B.V. Non-Voting Class A Share, one B.V. Non-Voting Class B Share and one share of our Class B common stock redeemed, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions, or, upon mutual agreement between such Principal Stockholder and us, (ii) an equivalent amount of cash, based on the trailing ten-day VWAP prior to the redemption date. Alternatively, upon the exercise of the Redemption Right, we (instead of HMH B.V.) will have the right, pursuant to the Call Right, to acquire each tendered bundle of one B.V. Non-Voting Class A Share, one B.V. Non-Voting Class B Share and one share of our Class B common stock directly from such Principal Stockholder for (a) one share of Class A common stock, subject to conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions, or, upon mutual agreement between such Principal Stockholder and us, (b) an equivalent amount of cash, based on the trailing ten-day VWAP prior to the redemption date.

Lock-up agreements

Following the expiration of such lock-up restrictions, the Principal Stockholders, subject to compliance with the Securities Act or exceptions therefrom, will be able to freely trade their Class A common stock, including any shares issued upon exchange of B.V. Non-Voting Shares (and, if applicable, the Mercury HoldCo Inc. shares). Other than with respect to our directors and executive officers, this restriction will not apply to the shares of our Class A common stock underlying any equity awards that may be granted in connection with the consummation of this offering. See “Underwriting” for a description of these lock-up provisions.

206

Rule 701

Accordingly, shares registered under such registration statements will be available for sale in the open market following the effective date, unless such shares are subject to vesting restrictions with us, Rule 144 restrictions applicable to our affiliates or the lock-up restrictions described above.

207

Certain ERISA considerations

The following is a summary of certain considerations associated with the acquisition and holding of shares of our Class A common stock by employee benefit plans that are subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Code, or employee benefit plans that are governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA), non-U.S. plans (as described in Section 4(b)(4) of ERISA) or other plans that are not subject to the foregoing but may be subject to provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws”), and entities whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”).

This summary is based on the provisions of ERISA and the Code (and related regulations and administrative and judicial interpretations) as of the date of this prospectus. This summary does not purport to be complete, and no assurance can be given that future legislation, court decisions, regulations, rulings or pronouncements will not significantly modify the requirements summarized below. Any of these changes may be retroactive and may thereby apply to transactions entered into prior to the date of their enactment or release. This discussion is general in nature and is not intended to be all inclusive, nor should it be construed as investment or legal advice.

General fiduciary matters

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”) and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of an ERISA Plan or the management or disposition of the assets of an ERISA Plan, or who renders investment advice for a fee or other compensation to an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

In considering an investment in shares of our Class A common stock with a portion of the assets of any Plan, a fiduciary should consider the Plan’s particular circumstances and all of the facts and circumstances of the investment and determine whether the acquisition and holding of shares of our Class A common stock is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to the fiduciary’s duties to the Plan, including, without limitation:

•

whether the investment is prudent under Section 404(a)(1)(B) of ERISA and any other applicable Similar Laws;

•

whether, in making the investment, the ERISA Plan will satisfy the diversification requirements of Section 404(a)(1)(C) of ERISA and any other applicable Similar Laws;

•

whether the investment is permitted under the terms of the applicable documents governing the Plan;

•

whether in the future there may be no market in which to sell or otherwise dispose of the shares of our Class A common stock;

•

whether the acquisition or holding of the shares of our Class A common stock will constitute a “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code (see the discussion under “—Prohibited transaction issues”); and

•

whether the Plan will be considered to hold, as plan assets, (i) only shares of our Class A common stock or (ii) an undivided interest in our underlying assets (see the discussion under “—Plan asset issues”).

208

Prohibited transaction issues

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is available. A party in interest or disqualified person who engages in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engages in such a non-exempt prohibited transaction may be subject to excise taxes, penalties and liabilities under ERISA and the Code. The acquisition and/or holding of shares of our Class A common stock by an ERISA Plan with respect to which the issuer, the initial purchaser or a guarantor is considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption.

Because of the foregoing, shares of our Class A common stock should not be acquired or held by any person investing “plan assets” of any Plan, unless such acquisition and holding will not constitute a non-exempt prohibited transaction under ERISA and the Code or a similar violation of any applicable Similar Laws.

Plan asset issues

Additionally, a fiduciary of a Plan should consider whether the Plan will, by investing in us, be deemed to own an undivided interest in our assets, with the result that we would become a fiduciary of the Plan and our operations would be subject to the regulatory restrictions of ERISA, including its prohibited transaction rules, as well as the prohibited transaction rules of the Code and any other applicable Similar Laws.

The U.S. Department of Labor (the “DOL”) regulations provide guidance with respect to whether the assets of an entity in which ERISA Plans acquire equity interests would be deemed “plan assets” under some circumstances. Under these regulations, an entity’s assets generally would not be considered to be “plan assets” if, among other things:

(a)

the equity interests acquired by ERISA Plans are “publicly offered securities” (as defined in the DOL regulations)—i.e., the equity interests are part of a class of securities that is widely held by 100 or more investors independent of the issuer and each other, are freely transferable and are either registered under certain provisions of the federal securities laws or sold to the ERISA Plan as part of a public offering under certain conditions;

(b)

the entity is an “operating company” (as defined in the DOL regulations)—i.e., it is primarily engaged in the production or sale of a product or service, other than the investment of capital, either directly or through a majority-owned subsidiary or subsidiaries; or

(c)

there is no significant investment by “benefit plan investors” (as defined in the DOL regulations)—i.e., immediately after the most recent acquisition by an ERISA Plan of any equity interest in the entity, less than 25% of the total value of each class of equity interest (disregarding certain interests held by persons (other than benefit plan investors) with discretionary authority or control over the assets of the entity or who provide investment advice for a fee (direct or indirect) with respect to such assets, and any affiliates thereof) is held by ERISA Plans, individual retirement accounts and certain other Plans (but not including governmental plans, foreign plans and certain church plans), and entities whose underlying assets are deemed to include plan assets by reason of a Plan’s investment in the entity.

Due to the complexity of these rules and the excise taxes, penalties and liabilities that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries, or other

209

persons considering acquiring and/or holding shares of our Class A common stock on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the acquisition and holding of shares of our Class A common stock. Purchasers of shares of our Class A common stock have the exclusive responsibility for ensuring that their acquisition and holding of shares of our Class A common stock complies with the fiduciary responsibility rules of ERISA and does not violate the prohibited transaction rules of ERISA, the Code or applicable Similar Laws. The sale of shares of our Class A common stock to a Plan is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by any such Plan or that such investment is appropriate for any such Plan.

Material U.S. federal income tax considerations for non-U.S. holders

The following is a summary of the material U.S. federal income tax considerations related to the purchase, ownership and disposition of our Class A common stock by a non-U.S. holder (as defined herein) that acquires such Class A common stock pursuant to this offering and holds our Class A common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally property held for investment). This summary is based on the provisions of the Code, U.S. Treasury regulations promulgated thereunder, administrative rulings and pronouncements and judicial decisions, all as in effect on the date hereof, and all of which are subject to change and differing interpretations, possibly with retroactive effect. Any such change or differing interpretation may alter the tax considerations that we describe in this summary. We have not sought and do not intend to seek any ruling from the IRS with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will agree with such statements and conclusions.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to non-U.S. holders in light of their personal circumstances. In addition, this summary does not address the Medicare tax on certain investment income, U.S. federal estate or gift tax laws, any state, local or non-U.S. tax laws or any tax treaties. This summary also does not address tax considerations applicable to investors that may be subject to special treatment under the U.S. federal income tax laws, such as:

•

banks, insurance companies or other financial institutions;

•

tax-exempt or governmental organizations;

•

dealers in securities;

•

“controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax;

•

traders in securities that use the mark-to-market method of accounting for U.S. federal income tax purposes;

•

persons subject to the alternative minimum tax;

•

entities or other arrangements treated as a partnership or pass-through entity for U.S. federal income tax purposes or holders of interests therein;

•

persons deemed to sell our Class A common stock under the constructive sale provisions of the Code;

•

certain former citizens or long-term residents of the United States;

•

persons that hold our Class A common stock as part of a straddle, appreciated financial position, synthetic security, conversion transaction or other integrated investment or risk reduction transaction;

•

“qualified foreign pension funds” as defined in Section 897(l)(2) of the Code and entities all the interest of which are held by qualified foreign pension funds; and

•

persons subject to special tax accounting rules as a result of any item of gross income with respect to the stock being taken into account in an applicable financial statement.

PROSPECTIVE INVESTORS ARE ENCOURAGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS (INCLUDING ANY POTENTIAL CHANGES THERETO) TO THEIR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR CLASS A COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS

211

OR UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

Non-U.S. holder defined

For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of our Class A common stock that is not for U.S. federal income tax purposes a partnership (or a partner therein) or any of the following:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•

an estate the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust (i) the administration of which is subject to the primary supervision of a U.S. court and which has one or more United States persons (within the meaning of Section 7701(a)(30) of the Code, a “United States person”) who have the authority to control all substantial decisions of the trust or (ii) which has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our Class A common stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner, upon the activities of the partnership and upon certain determinations made at the partner level. Accordingly, we urge partners in partnerships (including entities or arrangements treated as partnerships for U.S. federal income tax purposes) considering the purchase of our Class A common stock to consult their tax advisors regarding the U.S. federal income tax considerations of the purchase, ownership and disposition of our Class A common stock by such partnership.

Distributions on Class A common stock

The payment of distributions on our Class A common stock will be at the sole discretion of our board of directors. If we do make distributions of cash or other property (other than certain stock distributions) on our Class A common stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed our current and accumulated earnings and profits, the distributions will instead be treated as a non-taxable return of capital to the extent of the non-U.S. holder’s tax basis in our Class A common stock (and will reduce such tax basis, until such basis equals zero) and thereafter as capital gain from the sale or exchange of such Class A common stock. See “—Gain on disposition of Class A common stock.”

Subject to the discussions below under “—Backup withholding and information reporting” and “—Additional withholding requirements under FATCA” and with respect to effectively connected dividends (as discussed below), any distribution made to a non-U.S. holder on our Class A common stock generally will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the distribution unless an applicable income tax treaty provides for a lower rate. To claim the benefit of such a reduced treaty rate, a non-U.S. holder must timely provide the applicable withholding agent with a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form) certifying qualification for the reduced rate. A non-U.S. holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. holders are urged to consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

212

Dividends paid to a non-U.S. holder that are effectively connected with a trade or business conducted by the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment maintained by the non-U.S. holder in the United States) generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons (as defined under the Code). Such effectively connected dividends will not be subject to U.S. federal withholding tax (including backup withholding discussed below) if the non-U.S. holder satisfies certain certification requirements by providing the applicable withholding agent with a properly executed IRS Form W-8ECI certifying eligibility for exemption. If the non-U.S. holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include effectively connected dividends.

Gain on disposition of Class A common stock

Subject to the discussions below under “—Backup withholding and information reporting” and “—Additional withholding requirements under FATCA,” a non-U.S. holder generally will not be subject to U.S. federal income or withholding tax on any gain realized upon the sale, exchange or other taxable disposition of our Class A common stock unless:

•

the non-U.S. holder is an individual who is present in the United States for a period or periods aggregating 183 days or more during the calendar year in which the sale or disposition occurs and certain other conditions are met;

•

the gain is effectively connected with a trade or business conducted by the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by the non-U.S. holder in the United States); or

•

our Class A common stock constitutes a United States real property interest because we are or have been a United States real property holding corporation (a “USRPHC”) for U.S. federal income tax purposes at any time within the shorter of the five-year period preceding such disposition and the non-U.S. holder’s holding period for the Class A common stock.

A non-U.S. holder described in the first bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate as specified by an applicable income tax treaty) on the amount of such gain, which generally may be offset by U.S. source capital losses.

A non-U.S. holder whose gain is described in the second bullet point above generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons unless an applicable income tax treaty provides otherwise. If the non-U.S. holder is a corporation for U.S. federal income tax purposes whose gain is described in the second bullet point above, then such gain would also be included in its effectively connected earnings and profits (as adjusted for certain items), which may be subject to a branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty).

With respect to the third bullet above, a corporation generally is a USRPHC if the fair market value of its United States real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business. We believe that we currently are not a USRPHC for U.S. federal income tax purposes, and we do not expect to become a USRPHC for the foreseeable future. However, in the event that we become a USRPHC, as long as our Class A common stock is and continues to be “regularly traded on an established securities market” (within the meaning of the U.S. Treasury regulations), only a non-U.S. holder that actually or constructively owns, or owned at any time during

213

the shorter of the five-year period ending on the date of the disposition or the non-U.S. holder’s holding period for the Class A common stock, more than 5% of our Class A common stock will be treated as disposing of a U.S. real property interest and will be subject to tax on gain realized on the disposition of our Class A common stock as a result of our status as a USRPHC in the manner described in the preceding paragraph (except that the branch profits tax would not apply to a non-U.S. holder that is a corporation). If we were to become a USRPHC and our Class A common stock were not considered to be regularly traded on an established securities market, such holder (regardless of the percentage of stock owned) would be treated as disposing of a U.S. real property interest and would be subject to U.S. federal income tax in such manner on a taxable disposition of our Class A common stock, and a 15% withholding tax would apply to the gross proceeds from such disposition.

Backup withholding and information reporting

Any dividends paid to a non-U.S. holder must be reported annually to the IRS and to the non-U.S. holder. Copies of these information returns may be made available to the tax authorities in the country in which the non-U.S. holder resides or is established. Payments of dividends to a non-U.S. holder generally will not be subject to backup withholding if the non-U.S. holder establishes an exemption by properly certifying its non-U.S. status on an IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form).

Payments of the proceeds from a sale or other disposition by a non-U.S. holder of our Class A common stock effected by or through a U.S. office of a broker generally will be subject to information reporting and backup withholding (at the applicable rate, which is currently 24%) unless the non-U.S. holder establishes an exemption by properly certifying its non-U.S. status on an IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form) and certain other conditions are met. Information reporting and backup withholding generally will not apply to any payment of the proceeds from a sale or other disposition of our Class A common stock effected outside the United States by a non-U.S. office of a broker. However, unless such broker has documentary evidence in its records that the non-U.S. holder is not a United States person and certain other conditions are met, or the non-U.S. holder otherwise establishes an exemption, information reporting will apply to a payment of the proceeds of the disposition of our Class A common stock effected outside the United States by such a broker if it has certain connections with the United States.

Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability (if any) of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained, provided that the required information is timely furnished to the IRS. Non-U.S. holders should consult their tax advisors regarding the application of the information reporting and backup withholding rules to them.

Additional withholding requirements under FATCA

Sections 1471 through 1474 of the Code, and the U.S. Treasury regulations and administrative guidance issued thereunder (“FATCA”), impose a 30% withholding tax on any dividends paid on our Class A common stock if paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code) (including, in some cases, when such foreign financial institution or non-financial foreign entity is acting as an intermediary), unless (i) in the case of a foreign financial institution, such institution enters into an agreement with the U.S. government to withhold on certain payments, and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are non-U.S. entities with U.S. owners), (ii) in the case of a non-financial foreign entity, such entity certifies that it does not have any “substantial United States owners” (as defined in the Code) or timely provides the applicable withholding agent with a certification identifying the direct and indirect substantial United States owners of the entity (in either case,

214

generally on an IRS Form W-8BEN-E), or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules and provides appropriate documentation (such as an IRS Form W-8BEN-E). Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing these rules may be subject to different rules. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. Non-U.S. holders are encouraged to consult their own tax advisors regarding the effects of FATCA on an investment in our Class A common stock.

Although FATCA withholding generally could apply to gross proceeds on the disposition of our Class A common stock, proposed U.S. Treasury regulations (the “Proposed Regulations”) eliminate FATCA withholding on the gross proceeds from a sale or other disposition of our Class A common stock. The preamble to the Proposed Regulations states that taxpayers may rely on the Proposed Regulations pending finalization. However, there can be no assurance that the Proposed Regulations will be finalized in their present form.

If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally may obtain a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden). You should consult your tax advisor regarding the effects of FATCA on your investment in our Class A common stock.

The underwriters may agree to allocate a number of shares of Class A common stock to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make Internet distributions on the same basis as other allocations.

Morgan Securities LLC, Piper Sandler & Co. and Evercore Group L.L.C. for a period of 180 days after the date of this prospectus, other than the shares of our common stock to be sold in this offering.

The restrictions on our actions, as described above, do not apply to certain transactions, including (i) the issuance of shares of common stock or securities convertible into or exercisable for shares of our common stock pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options (including net exercise) or the settlement of phantom incentive awards, restricted stock units (“RSUs”) (including net settlement), in each case outstanding on the date of the underwriting agreement and described in this prospectus; (ii) grants of stock options, stock awards, restricted stock, RSUs or other equity awards and the issuance of shares of our common stock or securities convertible into or exercisable or exchangeable for shares of our common stock (whether upon the exercise of stock options or otherwise) to our employees, officers, directors, advisors or consultants pursuant to the terms of any equity compensation plan in effect as of the closing of this offering and described in this prospectus; (iii) our filing of any registration statement on Form S-8 relating to securities granted or to be granted pursuant to any plan in effect as of the closing of this offering and described in this prospectus or any assumed benefit plan pursuant to an acquisition or similar strategic transaction; or (iv) the issuance of shares of our common stock or securities convertible into or exercisable or exchangeable for shares of our common stock in connection with the corporate reorganization.

Our directors, director nominees and executive officers and the Principal Stockholders (such persons, the “lock-up parties”) have entered into lock-up agreements with the underwriters prior to the commencement of this offering pursuant to which each lock-up party, with limited exceptions, for a period of 180 days after the

217

date of this prospectus (such period, the “restricted period”), may not (and may not cause any of their direct or indirect affiliates to), without the prior written consent of each of J.P. Morgan Securities LLC, Piper Sandler & Co. and Evercore Group L.L.C., (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock, B.V. Shares or any securities convertible into or exercisable or exchangeable for our common stock or B.V. Shares (including, without limitation, common stock, B.V. Shares or such other securities which may be deemed to be beneficially owned by the lock-up party in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant (collectively with the common stock and B.V. Shares, the “lock-up securities”)), (2) enter into any hedging, swap or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of the lock-up securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of lock-up securities, in cash or otherwise, (3) make any demand for, or exercise any right with respect to, the registration of any lock-up securities (other than, in the case of each Principal Stockholder, preparation of a registration statement for the non-underwritten resale of our common stock, as set forth in the Registration Rights Agreement; provided that no such registration statement may be confidentially submitted or publicly filed until after the restricted period, and no preparation of an underwritten offering may take place), or (4) publicly disclose the intention to do any of the foregoing. Such persons or entities have further acknowledged that these undertakings preclude them from engaging in any hedging or other transactions or arrangements (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) designed or intended, or which would reasonably be expected to lead to or result in, a sale or disposition or transfer (by any person or entity, whether or not a signatory to such agreement) of any economic consequences of ownership, in whole or in part, directly or indirectly, of any lock-up securities, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of lock-up securities, in cash or otherwise.

The restrictions described in the immediately preceding paragraph and contained in the lock-up agreements between the underwriters and the lock-up parties do not apply, subject in certain cases to various conditions, to certain transactions, including (a) transfers of lock-up securities: (i) as a bona fide gift or gifts, or for bona fide estate planning purposes, (ii) by will, testamentary document or intestacy, (iii) to any immediate family member, or to any trust for the direct or indirect benefit of the lock-up party or its immediate family member, (iv) to a corporation, partnership, limited liability company or other entity of which the lock-up party and its immediate family members are the legal and beneficial owner of all of the outstanding equity securities or similar interests, (v) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (iv), (vi) if the lock-up party is a corporation, partnership, limited liability company, trust or other business entity, (A) to another corporation, partnership, limited liability company, trust or other business entity that is an affiliate of the lock-up party, or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the lock-up party or its affiliates or (B) as part of a distribution to members or shareholders or other equityholders of the lock-up party, (vii) by operation of law, such as pursuant to a qualified domestic order, divorce settlement, divorce decree or separation agreement, (viii) to us from an employee upon death, disability or termination of employment of such employee, (ix) as part of a sale of lock-up securities acquired in open market transactions after the completion of this offering, (x) to us in connection with the vesting, settlement or exercise of phantom incentive awards, RSUs, options, warrants or other rights to purchase shares of our common stock (including, in each case, by way of “net” or “cashless” exercise), including for the payment of exercise price and tax and remittance payments, provided that any shares of our common stock received upon such exercise, vesting or settlement would be subject to the restrictions in the immediately preceding paragraph, (xi) pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction approved by our board of

218

directors and made to all stockholders involving a change in control, provided that if such transaction is not completed, all such lock-up securities would remain subject to the restrictions in the immediately preceding paragraph, (xii) in the case of Akastor, to DNB Bank ASA in a bona fide transaction as collateral to secure obligations in connection with the multicurrency revolving credit facility agreement originally dated September 28, 2021 (as amended or amended and restated from time to time), or in connection with any restructuring, refinancing or amendment of such financing arrangement, provided that contemporaneously with foreclosure or other transfer (but not the pledge itself), the pledgee or other party must execute and deliver to the representatives of the underwriters a lock-up agreement, (xiii) to the lock-up party’s employer or an affiliate thereof if the lock-up party is a director or director nominee designated for appointment to our board of directors pursuant to the Stockholders’ Agreement, provided that the transferee must execute and deliver to the representatives of the underwriters a lock-up agreement, or (xiv) in connection with the corporate reorganization; (b) exercise of outstanding options, settlement of phantom incentive awards, RSUs or other equity awards or the exercise of warrants granted pursuant to letter agreements, plans or other equity compensation arrangements, as applicable, described in this prospectus, provided that any lock-up securities received upon such exercise, vesting or settlement would be subject to the restrictions in the immediately preceding paragraph; (c) the conversion of outstanding preferred stock, warrants to acquire preferred stock or convertible securities into shares of our common stock or warrants to acquire shares of our common stock, provided that any common stock or warrant received upon such conversion would be subject to the restrictions in the immediately preceding paragraph; and (d) the establishment by lock-up parties of trading plans pursuant to Rule 10b5-1 under the Exchange Act for the transfer of the lock-up securities, provided that such plan does not provide for the transfer of lock-up securities during the restricted period.

J.P. Morgan Securities LLC, Piper Sandler & Co. and Evercore Group L.L.C., in their sole discretion, may release the securities subject to any of the lock-up agreements with the underwriters described above, in whole or in part at any time.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act.

We have applied to list our Class A common stock on Nasdaq under the symbol “HMH.”

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of Class A common stock in the open market for the purpose of preventing or retarding a decline in the market price of the Class A common stock while this offering is in progress. These stabilizing transactions may include making short sales of Class A common stock, which involves the sale by the underwriters of a greater number of shares of Class A common stock than they are required to purchase in this offering, and purchasing shares of Class A common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares of Class A common stock referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares of Class A common stock, in whole or in part, or by purchasing shares of Class A common stock in the open market. In making this determination, the underwriters will consider, among other things, the price of shares of Class A common stock available for purchase in the open market compared to the price at which the underwriters may purchase shares of Class A common stock through the option to purchase additional shares of Class A common stock. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the Class A common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares of Class A common stock in the open market to cover the position.

219

The underwriters have advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the Class A common stock, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase Class A common stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares of Class A common stock as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the Class A common stock or preventing or retarding a decline in the market price of the Class A common stock, and, as a result, the price of the Class A common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on Nasdaq, in the over the counter market or otherwise.

Prior to this offering, there has been no public market for our Class A common stock. The initial public offering price will be determined by negotiations between us and the representatives. In determining the initial public offering price, we and the representatives expect to consider a number of factors, including:

•

the information set forth in this prospectus and otherwise available to the representatives;

•

our prospects and the history and prospects for the industry in which we compete;

•

an assessment of our management;

•

our prospects for future earnings;

•

the general condition of the securities markets at the time of this offering;

•

the recent market prices of, and demand for, publicly traded common stock of generally comparable companies; and

•

other factors deemed relevant by the underwriters and us.

Neither we nor the underwriters can assure investors that an active trading market will develop for our shares of Class A common stock, or that the shares of Class A common stock will trade in the public market at or above the initial public offering price.

At our request, J.P. Morgan Securities LLC, a participating underwriter, has reserved for sale, at the initial public offering price, up to approximately % of the shares of Class A common stock to be issued by the Company and offered by this prospectus for sale to certain entities and individuals, including some of our directors, director nominees, officers, employees, distributors, dealers, business associates and other parties related to HMH Inc. We expect the list of potential participants to be approximately 100 entities and individuals. These shares will be reserved for sale through the Directed Share Program to certain entities and individuals identified by management. Management will provide the list of potential participants to J.P. Morgan Securities LLC, which will administer the Directed Share Program. At this time, no indications of interest will be taken. Once the preliminary prospectus has been filed, an invitation package will be made available or sent to each person identified by management, which will include the preliminary prospectus and other Directed Share Program documentation. An invitation to participate in the Directed Share Program does not guarantee that the participant will receive an allocation of shares. Accordingly, we cannot provide any assurance that any director, director nominee, officer, employee or participant will receive an invitation or an allocation in the Directed Share Program. If a potential participant is interested in participating, that participant will be required to complete the required documentation and will be required to return such documentation to the program administrator. The program administrator will not accept funds from any participant until after the registration

statement of which this prospectus forms a part is declared effective, this offering is priced, and the participants are notified of their final allocation and given an opportunity to confirm that they wish to purchase the shares allocated to them. After the registration statement of which this prospectus forms a part has been declared effective and this offering is priced, we and the program administrator will prepare a final approved list of allocations. The program administrator will notify each participant who has been allocated shares of the number of shares that have been allocated and the total purchase price due upon confirmation of their participation. Thereafter, participants will be required to wire or transfer their funds to the program administrator. The shares under the Directed Share Program will be allocated following pricing and settle in the same manner as the shares sold to the general public. If purchased by our directors, director nominees, executive officers or the Principal Stockholders, these shares will be subject to a 180-day lock-up restriction. If these persons purchase reserved shares of Class A common stock, it will reduce the number of shares of Class A common stock available for sale to the general public. Any reserved shares of Class A common stock that are not so purchased will be offered by the underwriters to the general public on the same terms as the other shares of Class A common stock offered by this prospectus. The underwriters will receive the same discount from such reserved shares as they will from other shares of our Class A common stock sold to the public in this offering.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Certain of the underwriters and their respective affiliates have provided, and may in the future provide, a variety of these services to us and to persons and entities with relationships with us, for which they received or will receive customary fees and expenses. In addition, from time to time, certain of the underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future.

Other than in the United States, no action has been taken by us or the underwriters that would permit a public offering of the securities offered by this prospectus in any jurisdiction where action for that purpose is required. The securities offered by this prospectus may not be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction.

Glossary of selected terms

Bbl. One stock tank barrel, of 42 U.S. gallons liquid volume, used in this prospectus in reference to crude oil or other liquid hydrocarbons.

Bcm. Billion cubic meters of natural gas.

Bcm/MM Boe. Billion cubic meters of natural gas per million barrels of oil equivalent.

Blowout. An uncontrolled flow of reservoir fluids into the wellbore, and sometimes catastrophically to the surface. A blowout may consist of salt water, oil, natural gas or a mixture of these. Blowouts can occur in all types of E&P operations, not just during drilling operations. If reservoir fluids flow into another formation and do not flow to the surface, the result is called an underground blowout. If the well experiencing a blowout has significant open-hole intervals, it is possible that the well will bridge over (or seal itself with rock fragments from collapsing formations) down-hole and intervention efforts will be averted.

Boe. Barrel of oil equivalent.

Brent crude oil. Brent crude oil is the benchmark used for the light oil market in Europe, Africa and the Middle East, originating from oil fields in the North Sea between the Shetland Islands and Norway.

Brownfield. An oil or gas accumulation that has matured to a production plateau or even progressed to a stage of declining production.

Btu. British thermal unit. One Btu is the heat required to raise the temperature of one pound of liquid water by one degree Fahrenheit.

CAPEX. Capital expenditure.

Casing. Large-diameter, steel pipe lowered into an uncased portion of a well and cemented in place. Casing is run to provide structural integrity to the wellbore, protect fresh water formations, isolate a zone of lost returns or isolate formations with significantly different pressure gradients.

Cementing. To prepare and pump cement into place in a wellbore (primarily to fill and seal the gap between casing and the borehole wall).

CO₂e. Carbon dioxide equivalent.

Cold stacked. Describes an idled rig for which steps have been taken to preserve the rig and reduce certain costs, such as crew costs and maintenance expenses. Depending on the amount of time that a rig is cold stacked, significant expenditures may be required to return the rig to a “ready” state.

Completion. A generic term used to describe the assembly of down-hole tubulars and equipment required to enable safe and efficient production from an oil or gas well. The point at which the completion process begins may depend on the type and design of the well.

Day rates. The daily cost to the operator of renting the drilling rig and the associated costs of personnel and routine supplies.

DEAL. A technology platform that enables the installation of performance enhancing software modules called Smart Modules for topside drilling equipment. Smart Modules communicate with the drilling equipment controllers to optimize the operations required to drill a well. The platform is an open interface that enables a reliable, simple and effective gateway to the HMH drilling equipment. With DEAL^™ installed, adding of select Smart Modules is done with reduced downtime and risk.

A-1

DrillCERT. A global, continuous American Petroleum Institute certification program for marine drilling risers. Based on condition-based inspection methodology, the traditional five-year calendar-based inspection interval can often be extended up to a 12-year interval.

DrillPerform. A continuous improvement process carried out in close collaboration with our customers, ensuring that operational performance is assessed regularly to increase efficiency of well delivery, aid in incident investigations, support scenario training and improve safety while reducing operating expenses and environmental impact through data analytics and visualization of machine and crew analysis as well as implementation of performance enhancing technology.

Drilling rig. The machine used to drill a wellbore.

Drilling risers. The subsea riser is a buoyant pipe that the drillstring runs through and provides a connection between the rig and the blowout preventer or wellhead and transports hydraulic choke and kill fluid lines.

Drillstring. The combination of the drillpipe, the bottomhole assembly and any other tools used to make the drill bit turn at the bottom of the wellbore.

Greenfield. A new oil and gas field development.

GWh. Gigawatt hours.

Horizontal drilling. A subset of the more general term “directional drilling,” used where the departure of the wellbore from vertical exceeds about 80 degrees. Note that some horizontal wells are designed such that after reaching true 90-degree horizontal, the wellbore may actually start drilling upward. In such cases, the angle past 90 degrees is continued, as in 95 degrees, rather than reporting it as deviation from vertical, which would then be 85 degrees. Because a horizontal well typically penetrates a greater length of the reservoir, it can offer significant production improvement over a vertical well.

Hydraulic fracturing. A stimulation treatment routinely performed on oil and gas wells in low permeability reservoirs. Specially engineered fluids are pumped at high pressure and rate into the reservoir interval to be treated, causing a vertical fracture to open.

Hydrocarbon. A naturally occurring organic compound comprising hydrogen and carbon. Hydrocarbons can be as simple as methane, but many are highly complex molecules, and can occur as gases, liquids or solids. Petroleum is a complex mixture of hydrocarbons. The most common hydrocarbons are oil and natural gas.

MMbtu. One million British thermal units.

MM Bbls/day. Millions of barrels of crude oil or other liquid hydrocarbons per day.

MM Boe/day. Millions of barrels of oil equivalent per day.

Pile top drill rig. Specialized drilling equipment designed for setting up deep and large-diameter foundations in hard rock.

Psi. Pound per square inch.

Reverse circulation drilling. A form of percussion drilling that uses compressed air to flush material cuttings out of the drill hole in a safe and efficient manner.

RiCon. Our proprietary drilling riser lifecycle offering, which provides a current view of the riser condition. Software then identifies when maintenance is required and where to focus maintenance activities, reducing inspection costs.

A-2

Rig years. Represent a measure of the number of equivalent rigs operating during a given period.

Scope 1 emissions. Direct GHG emissions that occur from sources that are controlled or owned by an organization.

Scope 2 emissions. Indirect GHG emissions associated with the purchase of electricity, steam, heat or cooling.

Scope 3 emissions. GHG emissions that result from the end use of an organization’s products, as estimated per Category 11 (Use of Sold Product), as well as emissions from other business activities from assets not owned or controlled by the organization but that the organization indirectly impacts in its value chain.

SeaLytics. A technology platform that provides access to a customer’s control system data while maintaining critical cybersecurity protocol in an easily installed edge device. The system features real-time visualization, BOP systems status and the ability to manage maintenance activities. With optional cloud connectivity, stakeholders onshore can view and retrieve BOP data that has been historically difficult to retrieve securely. SeaLytics enables collaboration between onshore and offshore personnel, driving the quality, speed of decisions and corrective actions, resulting in reduced non-productive time. Additionally, we can process the data feed through proprietary analytics to help the customer operate and plan maintenance based on actual usage of a customer’s equipment.

SeaONYX. Our next-generation surface control system and operator interface software for well control equipment, based on an industry-proven programmable logic controller platform. Designed for reliability and ease-of-use, SeaONYX has SeaLytics built into it, providing all the benefits of real time monitoring and analytics.

Shale. A fine-grained, fissile, sedimentary rock formed by consolidation of clay- and silt-sized particles into thin, relatively impermeable layers.

Warm stacked. Describes a rig that is idled (not contracted) and maintained in a “ready” state with a crew sized to enable the rig to be quickly placed into service when contracted.

We have audited the accompanying balance sheets of HMH Holding Inc. (the Company) as of December 31, 2024, and as of April 29, 2024, and the related notes (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and as of April 29, 2024, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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.

Actual results could differ materially from those estimates.

Offering costs

In connection with the Company’s initial public offering, affiliates of the Company have or will incur accounting, legal and other costs, which will be reimbursed by the Company upon consummation of the initial public offering. Such costs will be deferred and recorded as a reduction to stockholder’s equity and recorded against the proceeds from the offering.

Unaudited pro forma consolidated financial statements

Introduction

HMH Holding Inc. (“HMH Inc.” or the “Company”), the issuer in the Offering (as defined below), is a holding company formed to own an interest in, and act as the sole managing member of, HMH Holding B.V. (“HMH B.V.”). The Company’s historical financial statements are those of HMH B.V., which is the Company’s accounting predecessor for financial reporting purposes.

The unaudited pro forma consolidated financial statements of the Company reflect the historical results of the Company on a pro forma basis to give effect to the following transactions (collectively, the “Transactions”), which are described in further detail below, as if they had occurred on March 31, 2025, for pro forma consolidated balance sheet purposes, and on January 1, 2024, for pro forma consolidated statements of income purposes:

•

the corporate reorganization as described under “Corporate reorganization” in this prospectus (the “Corporate Reorganization”);

•

the initial public offering of shares of the Company’s Class A common stock, par value $0.01 per share (“Class A common stock”), and the use of the net proceeds therefrom as described under “Use of proceeds” in this prospectus (the “Offering”). The net proceeds from the sale of the shares of Class A common stock (based on an assumed initial public offering price of $ per share) are expected to be $ , net of underwriting discounts of $ and other offering expenses payable by the Company of $ ; and

•

the recognition of share-based compensation expense totaling $ related to historical HMH B.V. shares.

The pro forma consolidated financial statements have been adjusted to include transaction accounting adjustments in accordance with generally accepted accounting principles in the United States of America (“GAAP”), linking the effects of the Transactions to the historical consolidated financial statements of HMH B.V.

The unaudited pro forma consolidated balance sheet of the Company is based on the historical consolidated balance sheet of HMH B.V., the Company’s accounting predecessor for financial reporting purposes, as of March 31, 2025 and includes pro forma adjustments to give effect to the Transactions as if they had occurred on March 31, 2025. The unaudited pro forma consolidated statements of income of the Company for the year ended December 31, 2024 and the three months ended March 31, 2025 are based on the historical consolidated statements of income of HMH B.V., giving effect to the Transactions as if they had occurred January 1, 2024.

The pro forma results are not necessarily indicative of financial results that would have been attained had the Transactions occurred on the date indicated or that could be achieved in the future because they necessarily exclude various operating expenses, such as incremental general and administrative expenses associated with being a public company. The transaction accounting adjustments are based on available information and certain assumptions that management believes are factually supportable. Therefore, the actual adjustments may differ from the pro forma adjustments. However, management believes that the assumptions provide a reasonable basis for presenting the significant effects of the Transactions as contemplated and the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma consolidated financial statements.

The unaudited pro forma consolidated financial statements and related notes are presented for illustrative purposes only. If the Transactions contemplated herein had occurred in the past, the Company’s operating results might have been materially different from those presented in the unaudited pro forma consolidated financial statements. The unaudited pro forma consolidated financial statements should not be relied upon as an indication of operating results that the Company would have achieved if the Transactions contemplated herein had taken place on the specified date. In addition, future results may vary significantly from the results

F-7

reflected in the unaudited pro forma consolidated statements of income and should not be relied upon as an indication of the future results the Company will have after the completion of the Transactions contemplated by the unaudited pro forma consolidated financial statements.

As described further under “Certain relationships and related party transactions—Tax Receivable Agreement” in this prospectus, in connection with the closing of the Offering, the Company will enter into a tax receivable agreement (the “Tax Receivable Agreement”) with the Principal Stockholders (as defined herein). The Tax Receivable Agreement will generally provide for the payment by the Company to the Principal Stockholders of 85% of the net cash savings, if any, in U.S. federal, state, local and foreign income tax and franchise tax that it actually realizes (or is deemed to realize in certain circumstances) in periods after the Offering as a result of, as applicable to each Principal Stockholder, (i) certain increases in tax basis that occur as a result of the Company’s acquisition (or deemed acquisition for U.S. federal income tax purposes) of all of such Principal Stockholder’s B.V. Voting Shares (as defined herein) in connection with the Offering or any portion of such Principal Stockholder’s B.V. Non-Voting Shares (as defined herein) pursuant to the exercise of the Redemption Right or the Company’s Call Right (each as defined elsewhere in this prospectus), (ii) the utilization of certain net operating losses of Mercury HoldCo Inc. in the event that the Company acquires Mercury HoldCo Inc. shares pursuant to the exercise of the Hybrid Redemption Right (as defined elsewhere in this prospectus) and (iii) imputed interest deemed to be paid by the Company as a result of, and additional tax basis arising from, any payments the Company makes under the Tax Receivable Agreement. The actual amount of deferred tax assets and related liabilities that the Company will recognize will differ based on, among other things, the timing of the redemptions of B.V. Non-Voting Shares (and, if applicable, acquisitions of Mercury HoldCo Inc. shares), the price of the Company’s shares of Class A common stock at the time of each redemption or acquisition and the applicable tax rates then in effect.

HMH Holding Inc.

Notes to unaudited pro forma consolidated financial statements

1. Basis of presentation, the offering and corporate reorganization

The historical financial information is derived from the financial statements of HMH B.V. included elsewhere in this prospectus. For purposes of the unaudited pro forma consolidated balance sheet, it is assumed that the Transactions had taken place on March 31, 2025. For purposes of the unaudited pro forma consolidated statements of income, it is assumed that the Transactions had taken place on January 1, 2024.

Immediately prior to the Offering and the corporate reorganization, (i) Baker Hughes Company (Nasdaq: BKR) and its wholly owned subsidiary, Baker Hughes Holdings LLC (collectively, “Baker Hughes”), and (ii) Akastor ASA (OSE: AKAST) and its wholly owned subsidiaries, Akastor AS, Mercury HoldCo AS and Mercury HoldCo Inc. (collectively, “Akastor” and, together with Baker Hughes, the “Principal Stockholders”), will collectively own all of the equity interests in HMH B.V.

Following the closing of the Offering, we anticipate incurring incremental general and administrative expenses as a result of operating as a publicly traded company, such as expenses associated with U.S. Securities and Exchange Commission (“SEC”) reporting requirements, including annual and quarterly reports, compliance expenses relating to the Sarbanes-Oxley Act of 2002, expenses associated with listing the Company’s Class A common stock on a stock exchange, independent auditor fees, legal fees, investor relations expenses, registrar and transfer agent fees, director and officer insurance expenses and director and officer compensation expenses. These incremental general and administrative expenses are not reflected in the historical financial statements of the Company’s predecessor. The Company estimates these direct, incremental general and administrative expenses initially will total approximately $ million per year. These direct, incremental general and administrative expenses are not reflected in the historical financial statements or in the unaudited pro forma consolidated financial statements.

HMH Inc. was incorporated as a Delaware corporation and wholly owned subsidiary of HMH B.V. in April 2024. Following the Offering and the Corporate Reorganization, HMH Inc. will be a holding company whose sole material asset will consist of a % equity interest in HMH B.V., with such equity interest consisting of Class A ordinary shares, which entitle the holder to one vote per share and track HMH B.V.’s U.S. operations (the “B.V. Voting Class A Shares”), and Class B ordinary shares, which entitle the holder to one vote per share and track HMH B.V.’s non-U.S. operations (the “B.V. Voting Class B Shares” and, together with the B.V. Voting Class A Shares, the “B.V. Voting Shares”). HMH B.V. will continue to wholly own all of the Company’s operating assets. After the consummation of the Transactions, HMH Inc. will own all of the B.V. Voting Shares. In connection with the Offering, we will engage in the following as part of the Corporate Reorganization:

•

HMH Inc. will issue shares of Class A common stock to purchasers in the Offering in exchange for the proceeds of the Offering;

F-12

•

Baker Hughes will sell B.V. Voting Class A Shares and B.V. Voting Class B Shares to HMH Inc. in exchange for $ in cash and will receive shares of the Company’s Class B common stock, par value $0.01 per share (“Class B common stock”), in exchange for relinquishing voting rights on of its B.V. Voting Class A Shares and of its B.V. Voting Class B Shares;

•

Akastor will sell B.V. Voting Class A Shares and B.V. Voting Class B Shares to HMH Inc. in exchange for $ in cash and will receive shares of Class B common stock in exchange for relinquishing voting rights on of its B.V. Voting Class A Shares and of its B.V. Voting Class B Shares; and

•

HMH Inc. will contribute, directly or indirectly, the remaining net proceeds from the Offering to HMH B.V. in exchange for newly issued B.V. Voting Shares, consisting of B.V. Voting Class A Shares and B.V. Voting Class B Shares, such that, after the exchange, HMH Inc. will hold, after taking into account the B.V. Voting Shares acquired from Baker Hughes and/or Akastor, one B.V. Voting Class A Share and one B.V. Voting Class B Share, respectively, for each share of Class A common stock outstanding following the Offering.

After giving effect to these Transactions and the Offering and the application of the net proceeds therefrom and assuming the underwriters’ do not exercise their option to purchase additional shares of Class A common stock in the Offering and prior to giving effect to the vesting of any LTI Awards (as defined elsewhere in this prospectus) that may vest in connection with the Offering and any future redemptions of B.V. Non-Voting Shares (and, if applicable, acquisitions of Mercury HoldCo Inc. shares) pursuant to the exchange agreement to be entered into in connection with the Offering by and among the Company, HMH B.V. and the Principal Stockholders:

•

the Principal Stockholders, collectively, will own all of the shares of Class B common stock, representing % total voting power of the Company’s capital stock, and will own all of the B.V. Non-Voting Shares, representing a % equity interest in HMH B.V. and 0% voting power of the equity in HMH B.V.;

•

Baker Hughes will own shares of Class B common stock, representing % total voting power of the Company’s capital stock, and will own B.V. Non-Voting Shares, representing a % equity interest in HMH B.V. and 0% voting power of the equity in HMH B.V.;

•

Akastor will own shares of Class B common stock, representing % total voting power of the Company’s capital stock, and will own B.V. Non-Voting Shares, representing a % equity interest in HMH B.V. and 0% voting power of the equity in HMH B.V.;

•

the investors in the Offering, collectively, will own all of the shares of Class A common stock, representing % total voting power of the Company’s capital stock; and

•

HMH Inc. will own all of the B.V. Voting Shares, representing a % equity interest in HMH B.V., which will represent 100% total voting power of the equity in HMH B.V.

If the underwriters exercise in full their option to purchase additional shares of Class A common stock in the Offering:

•

F-13

•

investors in the Offering, collectively, will own all of the shares of Class A common stock, representing % total voting power of the Company’s capital stock; and

•

HMH Inc. will own all of the B.V. Voting Shares, representing a % equity interest in HMH B.V., which will represent 100% total voting power of the equity in HMH B.V.

2. Transaction accounting adjustments

The unaudited pro forma consolidated financial statements have been adjusted to reflect the Transactions as follows:

Offering transactions

(a) Reflects the issuance and sale of shares of Class A common stock at an assumed initial public offering price of $ per share, net of underwriting discounts and commissions of $ million in the aggregate, and additional estimated expenses payable by the Company related to the Offering of approximately $ million and the use of the net proceeds therefrom as follows:

•

use $ million of the net proceeds from the Offering to pay the cash consideration portion of the purchase price to purchase an aggregate B.V. Voting Class A Shares and B.V. Voting Class B Shares from Baker Hughes and/or Akastor pursuant to the Corporate Reorganization; and

•

contribute all of the remaining net proceeds from the Offering to HMH B.V. in exchange for a number of B.V. Voting Class A Shares and B.V. Voting Class B Shares such that the number of B.V. Voting Class A Shares and B.V. Voting Class B Shares, respectively, held by the Company (taking into account the B.V. Voting Class A Shares and B.V. Voting Class B Shares acquired by the Company from the Principal Stockholders pursuant to the Corporate Reorganization) equals the number of shares of Class A common stock sold by the Company in the Offering. HMH B.V. intends to use $ million of the net proceeds received by it to repay all of the outstanding principal and accrued and unpaid interest under the Shareholder Loans (as defined elsewhere in this prospectus) from Baker Hughes Holdings LLC and Akastor AS, which totalled $134.6 million as of March 31, 2025, and any remaining amounts for general corporate purposes, which may include funding for acquisitions, working capital requirements, capital expenditures and the repayment, refinancing, redemption or repurchase of indebtedness or other securities.

In connection with the closing of the Offering, the Principal Stockholders exchanged % of their interests and HMH B.V. recognized a % increase in the tax basis of its assets in the unaudited pro forma consolidated financial statements. Assuming exchanges occur in future periods, the Company will not be obligated to make any payments under the Tax Receivable Agreement until the tax benefits arising from such transactions that gave rise to the payment are realized. For financial reporting purposes, the Company will assess its tax attributes in accordance with Accounting Standards Codification (“ASC”) Topic 740, Income Taxes, 740-10-30-5(e) to determine if it is more likely than not that it will realize any deferred tax assets. Following that assessment, the Company may recognize a liability under the Tax Receivable Agreement, reflecting the expected future realization of such tax benefits in accordance with ASC Topic 450, Contingencies. Amounts payable under the Tax Receivable Agreement are contingent upon, among other things, (i) generation of sufficient future taxable income during the term of the Tax Receivable Agreement and (ii) future changes in tax laws. In addition, the Company does not expect obligations under the Tax Receivable Agreement to impact earnings per share because those obligations will be recorded against the Company’s equity in accordance with ASC Topic 810, Consolidation, as these are common control transactions.

F-14

Share-based compensation expense

(b) Reflects share-based compensation expense related to historical share awards issued by HMH B.V.

In 2022, 2023 and 2024, the Company issued share-based compensation awards to management and certain employees which will vest when certain strategic goals are achieved. All of the awards are contingent on a liquidity event, which is defined as an IPO or a change of control of the Company. Upon completion of the Offering, the Company will recognize $ million in share-based compensation expense.

Report of independent registered public accounting firm

To the Shareholders and Board of Directors of HMH Holding B.V.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of HMH Holding B.V. and subsidiaries (the Company) as of December 31, 2024 and 2023, the related consolidated statements of income (loss), comprehensive income, changes in shareholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2024, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 consolidated financial statements are free of material misstatement, whether due to error or fraud.

HMH Holding B.V. and Subsidiaries

Notes to consolidated financial statements

1. Basis of presentation and summary of significant accounting policies

Description of business

HMH Holding B.V. (“HMH,” the “Company,” “we” or “our”) is a leading global provider of offshore and onshore drilling equipment and services.

The Company was operationally established with effect from October 1, 2021, through its acquisition of all shares in the MHWirth business from Akastor ASA and the Subsea Drilling Systems business from Baker Hughes Company. After these transactions, the shareholders were Baker Hughes Holdings LLC (50%), Akastor AS (25%) and Mercury HoldCo Inc. (25%). Baker Hughes Holdings LLC is a wholly owned subsidiary of Baker Hughes Company (together with Baker Hughes Holdings LLC, “Baker Hughes”), and Akastor AS and Mercury HoldCo Inc. are wholly owned subsidiaries of Akastor ASA (together with Akastor AS, Mercury HoldCo AS and Mercury HoldCo Inc., “Akastor”).

Basis of presentation

The accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S.” and such principles, “U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for annual financial information. The consolidated financial statements include the accounts of HMH and all of its subsidiaries and affiliates that it controls or variable interest entities for which the Company has determined it is the primary beneficiary. All intercompany accounts and transactions have been eliminated.

In the notes to the consolidated financial statements, all dollar amounts in tables are in thousands of dollars unless otherwise indicated. Certain columns and rows in the financial statements and notes thereto may not add due to the use of rounded numbers.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. Although management believes these assumptions to be reasonable, given historical experience, actual amounts and results could differ from these estimates. Estimates are used for, but are not limited to, determining the following: allowance for credit losses and inventory valuation reserves; recoverability of long-lived assets; revenue recognition on long-term contracts; valuation of goodwill; useful lives used in depreciation and amortization; income taxes and related valuation allowances; accruals for contingencies; actuarial assumptions to determine costs and liabilities related to employee benefit plans; stock-based compensation expense; warranty liabilities; valuation of derivatives; and the fair value of assets acquired and liabilities assumed in business combinations.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised and in any future periods affected.

Foreign currency

The consolidated financial statements are presented in U.S. dollars (“USD”). Assets and liabilities of non-U.S. operations with a functional currency other than USD have been translated into USD using the Company’s

F-22

period end exchange rates, and revenue, expenses and cash flows have been translated at average rates for the respective periods. Any resulting translation gains and losses are included in other comprehensive income (loss). The impact of remeasurement of monetary assets and liabilities denominated in currencies other than the functional currency of the Company or its subsidiaries is included in the consolidated statements of income.

Business combinations

Business combinations are accounted for using the acquisition method as of the acquisition date, which is the date when control is transferred to the Company.

Transaction costs are expensed as incurred.

Offering costs

In connection with the HMH Holding Inc.’s initial public offering, the Company has incurred or will incur accounting, legal and other costs, which will be reimbursed by HMH Holding Inc. upon consummation of the initial public offering. Such costs will be deferred and recorded as a reduction to stockholder’s equity and recorded against the proceeds from the offering. In the event the offering is aborted, such deferred offering costs will be expensed.

Cash and cash equivalents

Cash and cash equivalents include cash on hand, demand deposits held at banks and other short-term highly liquid investments with original maturity of three months or less. Restricted cash may include legally restricted deposits held as compensating balances against short-term borrowing arrangements, contracts entered into with others or company statements of intention with regard to particular deposits. The Company held an immaterial balance of restricted cash as of December 31, 2024 and December 31, 2023.

Accounts receivable

Accounts receivable is recorded at the invoiced amount, net of any allowance for credit losses. The Company evaluates the expected credit losses of accounts receivable, considering historical credit losses, current customer-specific information and other relevant factors when determining the allowance. The Company monitors customer payment history and current creditworthiness to determine that collectability of the related financial assets is reasonably assured. The Company also considers the overall business climate in which customers operate. For accounts receivable, a loss allowance matrix is utilized to measure lifetime expected credit losses. The matrix contemplates historical credit losses by age of receivables, adjusted for any forward-looking information and management expectations. Accounts receivable has been reduced by an allowance of $5.6 million and $6.7 million as of December 31, 2024 and 2023, respectively.

Interest-bearing receivables

Interest-bearing receivables include loans to related parties and are generally classified as financial assets measured at amortized costs using the effective interest method, less any impairment losses.

Derivative financial instruments

The Company uses derivative financial instruments such as currency forward contracts to hedge its exposure to foreign exchange risks arising from operational, financial and investment activities. These derivative financial instruments are accounted for as cash flow hedges since highly probable future cash flows are hedged (rather than committed revenues and expenses).

F-23

Derivative financial instruments are initially and subsequently measured at fair value. The effective portion of the hedge is recognized in accumulated other comprehensive income (loss) (“AOCI”) and reclassified into earnings when the hedged item affects earnings. Any gain or loss relating to the ineffective portion of derivative hedging instruments is recognized immediately in the consolidated statements of income as other non-operating income. Financial instruments, including derivatives, are only used to mitigate risk and are not used for trading and/or speculation purposes.

Hedge accounting is discontinued when the hedge no longer qualifies for hedge accounting. Disqualification occurs when the hedging instrument expires, is sold, terminated or exercised, or when a forecast transaction is no longer expected, or the hedge is no longer effective. When a hedge is discontinued, the gain or loss is deferred in the hedging reserve if the hedged transaction remains highly probable, until that transaction occurs; otherwise, it is expensed immediately. For cash flow hedges associated with forecast transactions that subsequently result in recognition of a non-financial asset, the amounts accumulated in the cash flow hedge reserve are included directly in the initial cost of the non-financial asset when recognized.

Interest-bearing borrowings

Interest-bearing borrowings are recognized initially at fair value less attributable transaction costs. Subsequent to initial recognition, interest-bearing borrowings are measured at amortized cost with any difference between cost and redemption value being recognized in the consolidated statements of income over the period of the borrowings on an effective interest basis.

Share capital

Ordinary shares are classified as equity. A repurchase of share capital is recognized as a reduction in equity and is classified as treasury shares. The Company has Class A ordinary shares and Class B ordinary shares, with equal rights for all shares. The holders of ordinary shares are entitled to receive dividends and are entitled to one vote per share at general meetings. Total outstanding shares are 200 shares, par value EUR 1 per share. As of December 31, 2024 and 2023, the Company had 100 Class A ordinary shares and 100 Class B ordinary shares outstanding.

Inventories

Inventories are recognized at the average acquisition cost or net realizable value, whichever is lower. The net sales value for raw materials and work in progress (goods under production) is calculated as the net realizable value of the finished products less the remaining production and sales costs. In the case of manufactured inventories and work in progress, costs include an appropriate share of attributable costs based on normal operating capacity.

Credit risk

The Company’s current receivables are spread over a broad and diverse group of customers across many countries. The Company grants credit to its customers and performs periodic credit evaluations of its customers’ financial conditions, including monitoring its customers’ payment history and current creditworthiness to manage this risk. The Company does not generally require collateral in support of its current receivables, but the Company may require payment in advance or security in the form of a letter of credit or a bank guarantee.

Having a concentration of customers in the energy industry may impact the Company’s overall exposure to credit risk as its customers may be similarly affected by prolonged changes in economic and industry

F-24

conditions. Some of the Company’s customers may experience extreme financial distress as a result of falling commodity prices and may be forced to seek protection under applicable bankruptcy laws, which may affect the Company’s ability to recover any amounts due from such customers. Furthermore, countries that rely heavily upon income from hydrocarbon exports have been and may in the future be negatively and significantly affected by a drop in oil prices, which could affect the Company’s ability to collect, timely or at all, from its customers in these countries, particularly national oil companies. Laws in some jurisdictions in which the Company operates or will operate could make collection difficult or time consuming.

The maximum exposure to credit risk at the reporting date equals the carrying amounts of financial assets. The Company does not hold collateral as security. Contract assets and liabilities are stated in Note 11—“Revenue from contracts with customers.”

Leases

Right-of-use assets

The Company recognizes a right-of-use asset at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any prepaid lease payments made at or before the commencement date, plus any initial direct costs. The right-of-use asset is subject to impairment assessment of non-financial assets and adjusted for certain remeasurement of the lease liability.

Lease liabilities

At the lease commencement date, the Company recognizes lease liability measured at the present value of the lease payments over the lease term, discounted using the Company’s incremental interest rate. Generally, the lease payments include fixed payments and variable lease payments that depend on an index or rate. Changes in future lease payments arising from a change in an index or rate are reflected as expense in the period the change occurs.

Short-term leases

The Company applies the recognition exemption to its leases that have a lease term of 12 months or less from the commencement date. Lease payments associated with the short-term leases are recognized as expenses on a straight-line basis over the lease term.

Lease term

The Company determines the lease term as the non-cancellable term of the lease, together with any periods covered by an option to extend the lease, if it is reasonably certain to be exercised, or any period covered by an option to terminate the lease if it is reasonably certain not to be exercised. The Company applies judgment in evaluating whether it is reasonably certain to exercise an extension option, considering all relevant factors that create economic incentive to exercise the extension option.

Property, plant and equipment

Property, plant and equipment are measured at cost less accumulated depreciation and impairment losses. The cost of self-constructed assets includes the cost of materials, direct labor, borrowing costs on qualifying assets, production overheads and the estimated costs of dismantling and removing the assets and restoring the site on which they are located.

F-25

If the components of property, plant and equipment have different useful lives, they are accounted for as separate components.

Subsequent costs

The Company capitalizes the cost of a replacement part or a component of property, plant and equipment when incurred if it can be measured reliably and it extends the useful life of the asset or qualifies as an asset improvement. All other costs are expensed as incurred.

Depreciation

Depreciation is normally recognized on a straight-line basis over the estimated useful lives of property, plant and equipment.

Estimates for useful life, depreciation method and residual values are reviewed annually. Assets are depreciated on a straight-line basis over their expected economic lives as follows:



Asset Classification	Useful life
Buildings		16-33 years
Machinery, equipment and software		3-16 years

Impairment

The Company reviewed the recoverability of long-lived assets, including finite-lived acquired intangible assets and property, plant and equipment, when events or changes in circumstances occur that indicate the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on the Company’s ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows (undiscounted) of the related operations. If these cash flows are less than the carrying value of such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. The Company concluded there were no indicators evident or other circumstances present that these assets were not recoverable and, accordingly, no impairment charges of long-lived assets were recognized for 2024 and 2023.

Goodwill

Goodwill represents the excess of purchase price paid by the Company over the fair market value of the net assets acquired. Goodwill is tested for impairment annually or whenever events or circumstances change indicating that the fair value of a reporting unit with goodwill could be below its carrying amount.

The Company performs impairment testing if any impairment indicators are identified. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the Company’s reporting unit is less than its carrying value. If the qualitative assessment indicates that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, a quantitative test is required. These calculations require management to estimate future cash flows expected to arise from these reporting units and an appropriate discount rate to reflect the time value of the money. The discounted cash flow is based on management’s forecast of operating performance for each reporting unit. The two main assumptions used in measuring goodwill impairment, which bear the risk of change and could impact the Company’s goodwill impairment analysis, include the cash flow from operations from each of the Company’s individual reporting units and the weighted average cost of capital. The starting point for each reporting unit’s cash flow from operations is the detailed annual plan or updated forecast. Cash flows beyond the specific operating plans were estimated using a terminal value calculation, which incorporated historical and forecasted financial cyclical

F-26

trends for each reporting unit and considered long-term earnings growth rates in the oil and gas industry. The financial and credit market volatility directly impacts the Company’s fair value measurement through the weighted average cost of capital that the Company uses to determine its discount rate. Key assumptions made by management also include assumptions for future market conditions, which require a high degree of judgment. If the carrying value of the reporting unit including goodwill exceeds its fair value, an impairment charge equal to the excess would be recognized up to a maximum amount of goodwill allocated to that reporting unit.

Other intangible assets, patents and rights and customer relationships

Acquired intangible assets are measured at cost less accumulated amortization and impairment losses.

Subsequent expenditures

Subsequent expenditures on intangible assets are capitalized only when they increase the future economic benefits embodied in the specific asset to which they relate. All other expenditures are expensed as incurred.

Amortization

Amortization is recognized in the consolidated statements of income on a straight-line basis over the estimated useful lives of intangible assets unless such useful lives are indefinite. Intangible assets are amortized from the date they are available for use. Amortization methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.

Research and development expenses

Expenditures on research activities undertaken with the prospect of obtaining new scientific or technical knowledge and understanding are recognized in the consolidated statements of income as incurred. These costs amounted to $7.1 million and $3.0 million for the years ended December 31, 2024 and 2023, respectively.

Development activities involving a plan or design for the production of new or substantially improved products or processes are expensed as incurred, unless the costs relate to an item that has an alternative future use. The Company follows Accounting Standards Codification (“ASC”) 350-40 to account for development costs incurred for the costs of computer software developed or obtained for internal use. ASC 350-40 requires such costs to be capitalized once certain criteria are met. Capitalized internal-use software costs are primarily comprised of cost of materials, direct labor overhead costs that are directly attributable to preparing the asset for its intended use and capitalized interest on qualifying assets. Costs are capitalized once the project is defined, funding is committed, and it is confirmed the software will be used for its intended use. Capitalization of these costs concludes once the project is substantially complete and the software is ready for its intended purpose.

Capitalized development expenditures are measured at cost less accumulated amortization and accumulated impairment losses.

Revenue from contracts with customers

Revenue recognition

F-27



Type of contract/revenue	Nature of performance obligations, including significant payment terms	Significant revenue recognition policies

Project and other manufacturing contracts	Under project and other manufacturing contracts, specialized products are built to a customer’s specifications and the assets have no alternative use to the Company. If a project or other manufacturing contract is terminated by the customer, the Company has an enforceable right to payment for the work completed to date. The contracts establish a legally enforceable milestone payment schedule as well as a legally enforceable right to receive payment for work completed. Each of the project or other manufacturing contracts normally includes a single, combined output for the customer, such as an integrated drilling equipment package. A single performance obligation, satisfied over time, is identified in each contract. Project and other manufacturing contracts revenue is presented in product revenue on the consolidated statements of income. Normal payment terms for project and other manufacturing contracts are 30 to 45 days.	Revenue from project and other manufacturing contracts is recognized according to progress. The input method used to measure progress is determined by reference to the costs incurred to date relative to the total estimated contract cost. Because of the uniqueness of the project and the required engineering in the initial phases of construction contracts, the Company may defer recognition of revenue, in excess of costs, until the point that progress can be measured reliably, which is when a project is approximately 20% complete. The Company considers milestone payments as variable consideration, with the full milestone payment representing the most likely outcome based on the Company’s historical experience. In addition, liquidated damages are recognized as a reduction of the transaction price unless it is highly probable that it will not be incurred. Disputed amounts and claims are only recognized when negotiations have reached an advanced stage, customer acceptance is highly likely and the amounts can be measured reliably.

Service revenue	Service revenue is generated from the rendering of various aftermarket services for installed products to customers. This offering includes field service, maintenance, overhaul and repair. Field service, maintenance and overhaul and repair services are satisfied over time as the customers simultaneously receive and consume the benefits provided by these services. For service contracts with multiple performance obligations, the Company allocates the transaction price based on the standalone selling price of each performance obligation. The Company determines the standalone selling price based on observable prices or will use an	Service revenue associated with field service, maintenance and overhaul and repair is recognized according to progress or the as-invoiced amounts, when the invoiced amounts directly correspond with the benefit of the services that are transferred to the customers.

Spare parts revenue	Revenue from spare parts, which involve physical transfer of goods, is satisfied at a point of time when control transfers to the customers, according to the contract terms. Normal payment terms for spare parts revenue are 30 to 45 days.	Revenue from spare parts is recognized when the customers obtain control of the goods, according to the contract terms, typically at physical shipment of goods.

Sale of products	This revenue type involves sale of products or equipment that are of a standard nature, not made to the customer’s specifications. Customers obtain control of these products according to the contract terms. The Company has assessed that these performance obligations are satisfied at a point of time. Revenue for sale of products is presented in product revenue on the consolidated statements of income. For contracts with multiple performance obligations, the Company allocates the transaction price based on the standalone selling price of each performance obligation. The Company determines the standalone selling price based on observable prices or will use an estimation method if observable prices are not available. Normal payment terms for sale of products are 30 to 45 days.	Revenue from these performance obligations is recognized when the customers obtain control of the goods, according to the contract terms.

Contract assets

Contract assets represent the amounts recognized as revenue by the Company for which the rights to payment have not become unconditional as of the reporting date. The contract assets are transferred to receivables when the rights to payment become unconditional, which usually occurs when invoices are issued to the customers.

Contract liabilities

A contract liability is recognized if a payment is received or a payment is due (whichever is earlier) from a customer before the Company transfers the related goods or services. Contract liabilities are recognized as revenue when the Company performs under the contract (i.e., transfers control of the related goods or services to the customer).

F-29

Income taxes

The Company operates through various subsidiaries in a number of countries throughout the world. Income taxes have been recorded based upon the income tax laws and rates of the countries in which the Company operates and earns income. The Company’s annual income tax expense is based on taxable income, statutory income tax rates and tax planning opportunities available in the various jurisdictions in which it operates. The determination and evaluation of the annual income tax expense and tax positions involves the interpretation of the tax laws in the various jurisdictions in which the Company operates. It requires significant judgment in determining the Company’s income tax expense and in evaluating its tax positions, including evaluating uncertainties and the use of estimates and assumptions regarding significant future events such as the amount, timing and character of income, deductions and tax credits. The Company’s tax filings are subject to examination by the taxing authorities in the jurisdictions where it conducts business. These examinations may result in assessments of additional income taxes that are resolved with the taxing authorities or through the courts.

Accrued liabilities

Warranties

Provision for warranties is recognized when the underlying products or services are sold. The provision is based on historical warranty data and a weighting of all possible outcomes against their associated probabilities.

A provision is made for expected warranty expenditures. The warranty period is normally 12 to 30 months depending on the specific customer contract and terms. See Note 12—“Accrued expenses” for further

information about provisions for warranty expenditures.

Restructuring

A restructuring provision is recognized when the Company has developed a detailed formal plan for the restructuring and has raised a valid expectation in those affected that the entity will carry out the restructuring by starting to implement the plan or announcing its main features to those affected by it. The measurement of a restructuring provision includes only the direct expenditures arising from the restructuring, which are those amounts that are both necessarily entailed by the restructuring and not associated with the ongoing activities of the entity.

Legal disputes and contingent liabilities

Given the scope of the Company’s worldwide operations, its subsidiaries are inevitably involved in legal disputes in the course of their business activities. In addition, the Company from time to time engages in mergers, acquisitions and other transactions that could expose the Company to financial and other non-operational risks, such as indemnity claims and price adjustment mechanisms resulting in recognition of deferred settlement

F-30

obligations. Provisions have been made to cover the expected outcome of the legal claims and disputes to the extent negative outcomes are likely and reliable estimates can be made. However, the final outcomes of these cases are subject to uncertainties, and resulting liabilities may exceed provisions recognized. The Company follows the development of these disputes on case-by-case basis and makes assessment based on all available evidence as at the reporting date.

Employee benefits

Defined contribution plans

Obligations for contributions by the Company to defined contribution plans are recognized as an expense in the consolidated statements of income as incurred.

Defined benefit plans

The Company’s net obligation in respect of defined benefit pension plans is calculated separately for each plan by estimating the amount of future benefit that employees have earned in the current and prior periods, discounting that amount and deducting the fair value of any plan assets.

The calculation of defined benefit obligations is performed annually by a qualified actuary using the projected unit credit method. The discount rate is the yield at the reporting date on government bonds or high-quality corporate bonds with maturities consistent with the terms of the obligations.

Remeasurement of the net defined benefit liability, which comprises actuarial gains and losses, and the return on plan assets (excluding interest) are recognized immediately in other comprehensive income. The Company determines the net interest expense (income) on the net defined benefit liability (asset) for the period by applying the discount rate used to measure the defined benefit obligation at the beginning of the annual period to the then-net defined benefit liability (asset), taking into account any changes in the net defined benefit liability (asset) during the period as a result of contributions and benefit payments. Net interest expense and other expenses related to defined benefit plans are recognized in the consolidated statements of income. When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in the consolidated statements of income. The Company recognizes gains and losses on the settlement of a defined benefit plan when the settlement occurs.

Fair value measurement

When available, the Company measures the fair value of a financial instrument using the quoted price in an active market for that instrument. If there is no quoted price in an active market, then the Company uses valuation techniques that maximize the use of relevant observable inputs and minimize the use of unobservable inputs. The chosen valuation technique incorporates all of the factors that market participants would take into account in pricing a transaction.

The best evidence of the fair value of a financial instrument on initial recognition is normally the transaction price. If the Company determines that the fair value on initial recognition differs from the transaction price and the fair value is evidenced neither by a quoted price in an active market for an identical asset or liability nor based on a valuation technique that uses only data from observable markets, the financial instrument is initially measured at fair value, and the difference between the fair value on initial recognition and the transaction price is recognized as a deferred gain or loss. Subsequently, the deferred gain or loss is recognized in profit or loss on an appropriate basis over the life of the instrument.

F-31

The determination of the fair value and the useful lives of the assets and liabilities acquired is performed, which requires the application of judgment. Fair values have been estimated by a range of different valuation techniques, such as the market approach, income approach and cost approach based on the techniques that have been assessed to be most appropriate for the type of assets or liability measured. All of these methods include a range of various assumptions where significant estimation has been exercised.

A number of the Company’s accounting policies and disclosures requires the measurement of fair values, for both financial and non-financial assets and liabilities, including:

(a)

Derivatives

(b)

Acquisitions

When measuring the fair value of an asset or a liability, the Company uses observable market data as far as possible. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows.

•

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities.

•

Level 2: Quoted prices for similar instruments in active markets; quoted prices of identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

•

Level 3: Significant inputs to the valuation model are unobservable.

If the inputs used to measure the fair value of an asset or a liability fall into different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement.

The Company recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

Investment in subsidiaries

For investments in subsidiaries that are not wholly owned, but where the Company exercises control, the equity held by the minority owners and their portion of net income are reflected as non-controlling interests.

On March 28, 2024, Hydril PCB Limited (“Hydril UK”), a subsidiary of the Company, issued shares representing a 30% non-controlling interest in its subsidiary, Hydril Pressure Controlling Arabia Limited (“Hydril Arabia”), to Tanajib Holding Company CJSC (“Tanajib”), in exchange for total consideration of $9.2 million, comprising $2.3 million of upfront consideration and $6.9 million of deferred consideration. The Company recognized cash of $2.3 million, related party accounts receivable—current of $2.2 million and related party notes receivable of $4.7 million.

Concentration risk

The Company had one customer that accounted for approximately 18.2% and $153.9 million of revenue for the year ended December 31, 2024. The Company expects to maintain its relationship with this customer. No customers accounted for more than 10% of revenue for the year ended December 31, 2023.

Recently adopted accounting standards

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosure.” The

F-32

ASU updates reportable segment disclosure requirements, primarily through requiring enhanced disclosures about significant segment expenses and information used to assess segment performance. The amendments do not change how segments are determined or aggregated, or how thresholds are applied to determine reportable segments. The Company adopted ASU No. 2023-07 during the year ended December 31, 2024. See Note 19—“Segment information and geographic data” for further detail.

New accounting standards to be adopted

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 provide for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 is effective for the Company prospectively to all annual periods beginning after December 15, 2025. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its disclosures.

In November 2024, the FASB issued ASU No. 2024-03, “Disaggregation of Income Statement Expenses (Subtopic 220-40).” The ASU requires public entities to disaggregate, in a tabular presentation, certain income statement expenses into different categories, such as purchases of inventory, employee compensation, depreciation and intangible asset amortization. The guidance is effective for fiscal years beginning after December 15, 2026, with early adoption permitted, and may be applied retrospectively. The Company is currently evaluating the impact of adopting the new ASU on its consolidated financial statements and related disclosures.

All other new accounting pronouncements that have been issued, but not yet effective, are currently being evaluated and at this time are not expected to have a material impact on the Company’s financial position or results of operations.

2. Inventories

Inventories, net of reserves of $105.4 million and $115.5 million in 2024 and 2023, respectively, consisted of the following as of December 31, 2024 and 2023:



	2024		2023
Stock of raw materials	$	26,354	$	38,859
Goods under production (work in progress)		45,585		7,982
Finished goods		208,018		195,387

Inventories, net	$	279,957	$	242,228

For the years ended December 31, 2024 and 2023, the Company recorded inventory write-downs of $5.7 million and $0.8 million, respectively.

3. Property, plant and equipment

Property, plant and equipment consisted of the following as of December 31, 2024 and 2023:



	2024			2023
Buildings and land	$	151,638		$	166,325
Machinery, equipment and software		85,822			83,673
Assets under construction		3,317			5,694

Total cost	$	240,777		$	255,692

Less: Accumulated depreciation		(42,093	)		(40,858	)

Property, plant and equipment, net	$	198,684		$	214,834

F-33

Depreciation expense relating to property, plant and equipment was $18.7 million and $18.9 million for the years ended December 31, 2024 and 2023, respectively, and was recorded in the consolidated statements of income within cost of sales and selling, general and administrative expenses.

4. Business combinations

Drillform Technical Services Ltd.

On July 17, 2024, Hydril PCB Canada Inc., a wholly owned subsidiary of HMH, completed its acquisition of all of the issued and outstanding shares of Drillform Technical Services Ltd. (“Drillform”) for a total purchase price of $24.7 million, consisting of $21.0 million in cash and $3.7 million in contingent consideration. Drillform holds a portfolio of patents and intellectual property related to equipment used in the handling of drill pipe during drilling operations and has a significant installed base of automated floor wrenches and catwalks. Drillform is based in Alberta, Canada and has facilities in Tulsa, Oklahoma and Abu Dhabi, United Arab Emirates. The Company accounted for the transaction as a business combination and allocated the total purchase price to assets acquired, liabilities and contingent consideration assumed based on their fair values at the date of acquisition. The purchase price allocation as of the date of acquisition was based on a preliminary valuation and is subject to revision as more detailed analyses are completed and additional information about the fair value of assets acquired and liabilities assumed becomes available.

The purchase price has been preliminarily allocated to major classes of assets and liabilities as follows:



Assets
Cash and cash equivalents	$	1,377
Accounts receivable		836
Inventory		3,043
Prepaid expenses and other current assets		110

Total current assets		5,366
Property and equipment		439
Intangible assets		11,000

Total assets	$	16,805


Liabilities and equity

Current liabilities
Customer deposits		3,885
Accounts payable		1,307
Deferred tax liability		1,036

Total current liabilities		6,228
Total debt and leases		2
Contingent consideration		3,700

Total liabilities	$	9,930

Equity consideration	$	21,000
Goodwill	$	14,125

The following table summarizes the fair value of acquired identifiable intangible assets as of the date of acquisition:


Development costs⁽¹⁾	$	6,000
Customer relationships⁽¹⁾		5,000

Total acquired intangible assets	$	11,000

(1)

The weighted-average amortization period for developed technology and customer relationships are 5 years and 2 years, respectively.

F-34

The contingent consideration consists of deferred payments by the Company to the acquiree’s prior equity and debt holders for three years, contingent on meeting the prescribed realized sales price and margin targets for certain types of units sold. The Company estimated the fair value of the contingent consideration using a probability-weighted discounted cash flow method under the income approach. The Company considered a range of outcomes, with the maximum being $12 million, and determined the most likely amount of undiscounted contingent consideration is $4.7 million.

Goodwill generated from this business combination is primarily attributable to expected synergies from the transaction and incremental revenue and profit to be derived from the Company’s expansion into global markets. The goodwill is not expected to be deductible for U.S. income tax purposes; however, it can be deducted for Canadian income tax purposes.

The Company incurred $3.6 million in transaction costs in connection with the acquisition, which were expensed as incurred and included in Selling, general and administrative expenses in the consolidated statement of income.

Following is the net impact of the Drillform acquisition on the Company’s consolidated statement of income since the date of acquisition:



	For the year ended December 31, 2024
Revenues	$	7,906
Net income		(2,760	)

Following are the supplemental consolidated financial results of the Company on an unaudited pro forma basis, as if the acquisition had been consummated on January 1, 2023:



	For the years ended December 31,
	2024		2023
Revenues	$	849,860	$	802,842
Net income attributable		49,753		10,829
Net income per common share—basic and diluted	$	248,765	$	54,145

These pro forma results were based on estimates and assumptions, which the Company believes are reasonable. They are not the results that would have been realized had the companies been combined during the periods presented and are not necessarily indicative of the Company’s consolidated results of operations in future periods. The pro forma results include adjustments related to purchase accounting, primarily amortization of intangible assets. Acquisition costs and other nonrecurring charges were immaterial and are included in the earliest period presented.

5. Goodwill

The changes in carrying value of goodwill are detailed by segment below:



	ESS			PCS		Total
Balance as of December 31, 2022,	$	184,296		$	103,229	$	287,525
Acquisition through business combinations		—			—		—
Currency translation differences		323			—		323

Balance as of December 31, 2023	$	184,619		$	103,229	$	287,848

Acquisition through business combinations⁽¹⁾		—			14,125		14,125
Currency translation differences		(1,034	)		—		(1,034	)

Balance as of December 31, 2024	$	183,585		$	117,354	$	300,939

(1)

Goodwill acquired was assigned to PCS segment. See Note 4—“Business combinations” for more information.

F-35

Goodwill is defined as an asset representing the future economic benefits arising from other assets acquired in a business combination or an asset acquisition by a not-for-profit entity that are not individually identified and separately recognized.

Goodwill mainly arose from the formation of the Company in 2021 as this was considered to be a business combination and accounted for using the acquisition method. For the purpose of impairment testing, goodwill has been allocated to the Company’s reporting units, Equipment and System Solutions (“ESS”) and Pressure Control Systems (“PCS”), which represents the lowest level at which goodwill is monitored in management reporting.

As a result of the Company’s goodwill impairment assessment performed in the years ended December 31, 2024 and 2023, there were no goodwill impairments deemed necessary.

6. Intangible assets

Intangible assets consisted of the following as of December 31, 2024 and 2023:



			2024									2023
	Useful life		Gross carrying amount		Accumulated amortization			Net carrying amount		Gross carrying amount		Accumulated amortization			Net carrying amount
Patents and rights		3-5 years	$	20,107	$	(11,627	)	$	8,480	$	20,550	$	(8,890	)	$	11,660
Customer relationships		2-20 years		112,893		(37,135	)		75,758		107,893		(25,081	)		82,812
Development costs		3-8 years		66,049		(15,133	)		50,916		65,903		(13,131	)		52,772

Amortization expense recognized for the years ended December 31, 2024 and 2023 was $20.7 million and $19.9 million, respectively, and was recorded in the consolidated statements of income within cost of sales and selling, general and administrative expenses.

The following table outlines the estimated future amortization expense related to intangible assets held as of December 31, 2024:



Year ending December 31,	Amortization expense
2025	$	25,293
2026		25,255
2027		23,051
2028		9,968

Total	$	135,154

7. Financial instruments

Accounting classifications and fair values

For financial instruments measured at fair value, the levels in the fair value hierarchy are as shown below.

Level 1—Fair values are based on prices quoted in an active market for identical assets or liabilities.

F-36

Level 2—Quoted prices for similar instruments in active markets; quoted prices of identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3—Fair values are based on unobservable inputs, mainly based on internal assumptions used in the absence of quoted prices from an active market or other observable price inputs

The following tables set forth the Company’s financial instruments that are measured at fair value on a recurring basis by level within the fair value hierarchy as of December 31, 2024 and 2023:



							2024
	Level 1		Level 2		Level 3⁽¹⁾		Total

The fair value (Level 3) of the seller’s receivable against Akastor AS on proceeds from the sales or liquidation of Step Oiltools B.V. (“Step Oiltools”) has been remeasured to zero as of December 31, 2024 and 2023.

The carrying value of cash and cash equivalents, current receivables, accounts payable and accrued expenses approximates fair value based on the short-term nature of these accounts.

Cash flow hedges

The Company uses cash flow hedging primarily to mitigate the effects of foreign exchange rate changes on future transactions denominated in foreign currencies. Accordingly, the vast majority of the Company’s derivative activity in this category consists of forward currency exchange contracts. Changes in the fair value of cash flow hedges are recorded in the hedge reserve in AOCI and are recorded in earnings in the period in which the hedged transaction occurs. See the statements of change in shareholders’ equity for further information on activity in AOCI for cash flow hedges. The maximum term of cash flow hedges is under 24 months as of December 31, 2024 and 2023.

The Company hedges its future transactions in foreign currencies with external banks. The foreign exchange derivatives are subject to hedge accounting. Hedges qualifying for hedge accounting are classified as cash flow hedges (hedges of highly probable future revenues and/or expenses).

F-37

The hedged transactions in foreign currency that are subject to cash flow hedge accounting are highly probable future transactions expected to occur at various dates during the next one to four years, depending on progress in the projects. Gains and losses on forward foreign exchange contracts are recognized in other comprehensive income and reported as measurement adjustments within AOCI in equity until they are recognized in the consolidated statements of income in the period or periods during which the hedged transactions affect the consolidated statements of income. If the forward foreign exchange contract is rolled due to a change in timing of the forecasted cash flow, the settlement effect is included in contract assets or contract liabilities.

Derivative financial assets and liabilities are included in the other current assets and other current liabilities on the consolidated balance sheet.

The following table presents the fair value of the derivative financial instruments and a maturity analysis of the derivatives cash flows. Valuation techniques and inputs of forward contracts are based on the quoted forward exchange rate.

9. Leases

The Company has mostly property leases on a number of locations worldwide. The leases typically run for a period of two to ten years and some of the leases have extension options. The Company also has an immaterial amount of lease agreements related to cars, machinery, information technology (“IT”) equipment and office equipment. These leases have an average lease period of two to three years, generally with no renewal options included.

F-39

The Company applies the short-term lease recognition exemptions for leases of property or machinery with a lease term of 12 months or less. Short-term lease expense for the years ended December 31, 2024 and 2023

was $0.2 million and $0.9 million, respectively.

The lease agreements do not impose any covenants or restrictions.

Lease liabilities expiring within the following periods from the balance dates

Some property leases contain extension or termination options exercisable before the end of the non-cancellable period. They are used to maximize operational flexibility in terms of managing the assets used in the Company’s operations. The extension and termination options held are exercisable only by the Company and not by the respective lessor. The Company assesses at the lease commencement date whether it is reasonably certain to exercise the extension or termination options.

Most extension options in office leases have not been included in the lease liability, because the Company expects to be able to replace the assets without significant cost or business disruption. Most of the early termination options are not considered in the lease term either as the Company assesses it as reasonably certain that the leases will not be terminated early. If the Company had exercised the extension options in significant property leases as of December 31, 2024, the Company estimates potential future lease payments (undiscounted) would have had an immaterial impact to the lease liability.

Debt agreements

Senior Secured Floating Rate Bonds (HMH01)

The Company’s $150.0 million aggregate principal amount of its senior secured bonds (ISIN code: NO0012428996) (the “Senior Secured Floating Rate Bonds”) were refinanced on or around November 15, 2023 and were repaid at 104.71562% of the nominal amount (plus accrued and unpaid interest of the redeemed amount) on November 22, 2023 and November 28, 2023. This transaction resulted in a $6.4 million loss on extinguishment of the debt, which is recognized in the consolidated statement of income for the year ended December 31, 2023.

Senior Secured Bonds (HMH02)

On or around November 15, 2023, the Company issued $200.0 million aggregate principal amount of its senior secured bonds (ISIN code: NO0013063495) (the “Senior Secured Bonds”), which accrue interest at a fixed rate of 9.875% per annum and mature on November 16, 2026. The Company will also incur additional interest of 1% per annum until the Senior Secured Bonds are listed on the Oslo Stock Exchange. The Senior Secured Bonds are secured by liens on substantially all of the Company’s assets, including the equity of its material subsidiaries,

F-41

and guarantees, either directly or indirectly, from its material subsidiaries. The security of the Senior Secured Bonds is subject to the Intercreditor Agreement (as defined herein) with the facility agent under the Revolver (as defined herein). The agreement governing the Senior Secured Bonds includes customary representations and warranties, affirmative covenants and certain restrictive covenants that may limit the Company’s ability to, among other things, incur additional indebtedness, guarantee obligations, incur liens, make investments, loans or capital expenditures, sell or dispose of assets, enter into mergers or consolidations, enter into transactions with affiliates or make or declare dividends. The Senior Secured Bonds also require the Company to maintain at all times a minimum liquidity of not less than $30.0 million, a gearing ratio of Consolidated Net Total Borrowings to Consolidated Total Equity (each as defined in the agreement governing the Senior Secured Bonds) not to exceed 1.00 to 1.00 and an interest cover ratio of Adjusted EBITDA to Net Interest Expenses (each as defined in the agreement governing the Senior Secured Bonds) of not less than 2.50 to 1.00. Subject to compliance with certain conditions, the Company is permitted to increase its borrowings under the Senior Secured Bonds by up to $75.0 million, and the Company is also permitted to enter into certain bridge financing facilities with the lender(s) party thereto. The Company intends to list the Senior Secured Bonds on the Oslo Stock Exchange during the first half of 2025. The agreement governing the Senior Secured Bonds contains customary events of default. If an event of default exists under the Senior Secured Bonds, the lenders will be able to accelerate the maturity of the Senior Secured Bonds and exercise other rights and remedies. If an event of default exists under the Revolver, a cross-default will be triggered under the Senior Secured Bonds, and the bondholders thereunder will be able to accelerate the maturity of the Senior Secured Bonds and exercise other rights and remedies.

The Senior Secured Bonds are redeemable, at the Company’s option, (i) prior to May 16, 2025, at a price equal to the make-whole amount and (ii) beginning on May 16, 2025, at a premium of 104.938%. The redemption premium then declines in steps until May 16, 2026, at which time the Company may redeem the bonds at a premium of 100.500%. The redemption premium then falls away at the maturity date, at which time the Company may redeem the bonds at par value.

Following a Change of Control or a Share De-Listing Event (each as defined in the agreement governing the Senior Secured Bonds), the Company can be required to prepay the Senior Secured Bonds at 101% of the nominal amount of the bonds being repaid.

Following a material asset sale, the Company can be required to prepay the Senior Secured Bonds at 100% of the nominal amount of the bonds being repaid, up to 50% of the gross proceeds of the material asset sale.

On December 11, 2024, the holders of the Senior Secured Bonds agreed, in exchange for a one-time consent fee, to amend certain terms of the Senior Secured Bonds to permit implementation of the corporate reorganization and the listing of HMH Holding Inc.’s Class A common stock on The Nasdaq Global Select Market (“Nasdaq”), and the documentation formally implementing the same became effective as of February 12, 2025.

Shareholder Loans

On October 1, 2021, the Company entered into a loan agreement with related parties, Baker Hughes Holdings LLC and Akastor AS (as amended, the “Shareholder Loan Agreement”), to finance its operating and finance activities. Baker Hughes Holdings LLC provided an $80.0 million term loan under the Shareholder Loan Agreement (the “Baker Hughes Shareholder Loan”), and Akastor AS provided a $20.0 million term loan under the Shareholder Loan Agreement (the “Akastor Shareholder Loan” and, together with the Baker Hughes Shareholder Loan, the “Shareholder Loans”). The Shareholder Loans mature on the earliest to occur of October 1, 2026 or a liquidation event (as defined in the Shareholder Loan Agreement) such as the consummation of HMH Holding Inc.’s initial public offering. As of December 31, 2024, the total amount of principal and accrued and unpaid interest outstanding under the Shareholder Loans was $131.9 million, which

F-42

included $103.8 million outstanding under the Baker Hughes Shareholder Loan and $28.1 million outstanding under the Akastor Shareholder Loan. The Company also agreed to pay Baker Hughes and Akastor for certain deferred tax assets related to the contributed businesses in the amounts of approximately $0.2 million and $2.2 million, respectively, with such payment made by way of an increase to the Shareholder Loans. Such additional amounts relating to deferred tax assets are reflected in the Shareholder Loans’ balances as of December 31, 2024. The Shareholder Loans bear interest at a rate of 8.0% per annum. The Shareholder Loans are unsecured. The Shareholder Loan Agreement includes certain restrictive covenants that may limit the Company’s ability to, among other things, incur additional indebtedness or make or declare dividends. The Shareholder Loan Agreement contains customary representations and warranties, affirmative covenants and events of default. If an event of default exists under the Shareholder Loan Agreement, the lenders will be able to accelerate the maturity of the Shareholder Loans and exercise other rights and remedies. Subject to certain notice requirements, the Company may voluntarily prepay outstanding loans under the Shareholder Loan Agreement in whole or in part without premium or penalty.

Revolving Credit Facility 2023 ($50 million)

On November 20, 2023, the Company, DNB Bank ASA, as agent, certain financial institutions party thereto as lenders (the “Revolver Lenders”) and DNB Markets, a part of DNB Bank ASA, and Nordea Bank Abp, filial i Norge, as mandated lead arrangers and bookrunners, entered into a senior facility agreement (the “Revolver”) pursuant to which the Revolver Lenders provide revolving credit financing to the Company in an aggregate principal amount of up to $50.0 million. The scheduled maturity date of the Revolver is May 16, 2026.

Borrowings under the Revolver bear interest at the compounded reference rate, which is the applicable Secured Overnight Financing Rate ("SOFR") plus the applicable credit spread adjustment, plus a margin of 3.50% to 4.25% based on the Company’s most recent leverage ratio. In addition to paying interest on outstanding principal under the Revolver, the Company is required to pay a quarterly commitment fee equal to 40% of the applicable margin on the unused available commitments.

The Revolver is secured by liens on substantially all of the Company’s assets, including the equity of its material subsidiaries, and guarantees, either directly or indirectly, from its material subsidiaries. The security of the Revolver is subject to the Intercreditor Agreement with the trustee under the Senior Secured Bonds. The Revolver includes certain restrictive covenants that may limit the Company’s ability to, among other things, incur additional indebtedness, guarantee obligations, incur liens, make investments, loans or capital expenditures, sell or dispose of assets, enter into mergers or consolidations, enter into transactions with affiliates or make or declare dividends. The Revolver also requires the Company to maintain at all times a minimum liquidity of not less than $30.0 million, a gearing ratio of Consolidated Net Total Borrowings to Consolidated Total Equity (each as defined in the Revolver) not to exceed 1.00 to 1.00 and an interest cover ratio of Adjusted EBITDA to Net Interest Expenses (each as defined in the Revolver) of not less than 2.50 to 1.00. The Revolver contains customary representations and warranties, affirmative covenants and events of default. If an event of default exists under the Revolver, the Revolver Lenders will be able to accelerate the maturity of the Revolver and exercise other rights and remedies. If an event of default exists under the Senior Secured Bonds, a cross-default will be triggered under the Revolver, and the Revolver Lenders will be able to accelerate the maturity of the Revolver and exercise other rights and remedies. Subject to certain notice requirements and certain partial prepayment amount restrictions, the Company may voluntarily prepay outstanding loans under the Revolver in whole or in part without premium or penalty. Following a Change of Control (as defined in the Revolver), the Company can be required to prepay the loans in whole if the parties do not reach an agreement to continue the loan.

F-43

Intercreditor Agreement

On November 22, 2023, the facility agent under the Revolver and the trustee under the Senior Secured Bonds entered into a pari passu intercreditor agreement (the “Intercreditor Agreement”) (subject to the super senior ranking of the Company’s obligations under the Revolver and the hedging liabilities, in each case, with respect to the applications of proceeds thereunder) governing (i) the relative priorities of their respective security interests in the assets securing the Revolver, the Senior Secured Bonds and certain future secured indebtedness and (ii) certain other matters relating to the administration of their respective security interests, including the occurrence of an insolvency event.

Credit Line in China

On August 22, 2023, the Company entered into a credit line agreement (the “Credit Line in China”) with Bank of China Shanghai Pudong branch (the “Credit Line in China Lender”) pursuant to which the Credit Line in China Lender provided a credit line in an aggregate principal amount of up to Chinese renminbi (RMB) 10.0 million.

Borrowings under the Credit Line in China bore interest at the compounded reference rate, which was the applicable China Loan Prime Rate minus margin 0.4%. Interest was paid quarterly in the last month of each quarter. There was no quarterly commitment fee or guarantee requirement based on the Company’s financial status. The borrowing length for each withdrawal was one year. The Credit Line in China could only be used for the Company’s daily operations and could not be used to purchase real estate, re-lend to other companies or make investments.

As of December 31, 2023, the aggregate principal amount outstanding under the Credit Line in China was $1.0 million. As of December 31, 2024, there is no balance outstanding for the Credit Line in China. The Credit Line in China expired by its terms on July 26, 2024, and all borrowings under the Credit Line in China have matured and been repaid by the Company as of September 22, 2024.

Fair values

The fair value of the Senior Secured Bonds was based on Bloomberg on December 31 2024. The fair value of the Senior Secured Bonds derived from Bloomberg amounts to 104.02%. The fair value of the Senior Secured Bonds was derived from the price of Senior Secured Bonds as listed on the Oslo Stock Exchange, as applicable, on December 21, 2024. For the remaining debt instruments, the book values of each instrument approximate its respective carrying amount, as these interest rates are variable in nature and are reflective of market rates.

14. Share-based compensation

The Company had the following share-based payment arrangements during the periods presented:

Founders’ phantom equity award program

On January 31, 2022, the grant date, the Board of Directors of the Company (“Board”) established an award program to management and certain employees to entitle them to payment when certain strategic goals are achieved.

On January 31, 2022, the Board awarded and issued $10.0 million to the participants of the program based on an equity value of $600.0 million, which was deemed to be the fair value of the Company’s equity.

On September 1, 2024, the Board awarded and issued $1.3 million to the participants of the program based on an equity value of $600.0 million, consistent with the original grants.

The amount of the payment is determined based on the increase/decrease of the equity value of the Company. Vesting requires continuous service through the vesting date and is contingent upon the occurrence of a change in control or an IPO (each as defined in the applicable award agreement). The program expires at the end of the eight-year period after the grant date. In the event of a change of control, the settlement may be in cash, shares or other form of consideration at the discretion of the Board. In the event of an IPO, the settlement shall be made in shares of the resulting public company.

2022 Long-term incentive program

On September 1, 2022, the grant date, the Board established a share-based incentive program covering certain key personnel employees to entitle them to payment when certain strategic goals are achieved.

On September 1, 2022, the Board awarded and issued $5.0 million to the participants of the program based on an equity value of $600.0 million, which was deemed to be the fair value of the Company’s equity. The award contains two components: a time-based restricted equity award (“RSU”) and a performance-based award (“PSU”). Vesting requires continuous service through the vesting date. The RSU has a three-year ratable vesting from the grant date and the PSU has a three-year cliff vesting based on specified performance metrics. Both components are contingent upon a change in control or an IPO or event making equity ownership interest in the Company publicly available. The program expires at the end of the eight-year period after the grant date. In the event of a change in control, the settlement may be in cash, shares or other form of consideration at the discretion of the Board. In the event of an IPO or other public liquidity event, the settlement shall be made in shares of the resulting public company.

F-47

2023 Long-term incentive program

On September 1, 2023, the grant date, the Board established a share-based incentive program covering certain key personnel employees to entitle them to payment when certain strategies goals are achieved.

On September 1, 2023, the Board awarded and issued $5.0 million to the participants of the program based on an equity value of $700.0 million, which was deemed to be the fair value of the Company’s equity. The award contains two components: an RSU award and a PSU award. The RSU has a three-year ratable vesting from the grant date, whereas the PSU has a three-year cliff vesting based on specified performance metrics. Both awards are contingent upon a change of control. The program will fully vest over three years and upon a change of control event. The program expires at the end of the eight-year period after the grant date. In the event of a change in control, the settlement may be in cash, shares or other form of consideration at the discretion of the Board. In the event of an IPO, the settlement shall be made in cash or shares of the resulting public company at the discretion of the Board.

All of the awards above are contingent on a liquidity event, which is defined as an IPO or a change of control of the Company. As of December 31, 2024, the Company did not believe that a liquidity event as defined in the award agreements was probable and will not be probable until the occurrence of the liquidity event. Therefore, the Company did not recognize any compensation expense related to these awards.

2024 Long-term incentive program

On September 1, 2024, the grant date, the Board established a share-based incentive program covering certain key personnel employees to entitle them to payment when certain strategies goals are achieved.

On September 1, 2024, the Board awarded and issued $5.0 million to the participants of the program based on an equity value of $1.0 billion, which was deemed to be the fair value of the Company’s equity. The award contains two components: an RSU award and a PSU award. The RSU has a three-year ratable vesting from the grant date, whereas the PSU has a three-year cliff vesting based on specified performance metrics. Both awards are contingent upon a change of control. The program will fully vest over three years and upon a change of control event. The program expires at the end of the eight-year period after the grant date. In the event of a change in control, the settlement may be in cash, shares or other form of consideration at the discretion of the Board. In the event of an IPO, the settlement shall be made in cash or shares of the resulting public company at the discretion of the Board.

Unvested equity awards

The compensation expense not yet recognized for all awards listed above was approximately $15.5 million in the aggregate as of December 31, 2024.

15. Employee benefit expenses

Pension plans in Germany and Norway

Pension costs represent the future pension entitlement earned by employees in the financial year. In a defined contribution plan, the Company is responsible for paying an agreed contribution to the employee’s pension

F-48

assets. In such a plan, this annual contribution is also the cost. In a defined benefit plan, it is the Company’s responsibility to provide a certain pension. The measurement of the cost and the pension liability for such arrangements is subject to actuarial valuations. The main pension liabilities relate to Norway and Germany. The welfare and support fund is closed for new entries. The welfare and support fund is recorded as other non-current liabilities and not as pension.

Pension plans in Germany

The main pension arrangement in Germany is a general pension plan organized by the German Government. This arrangement provides the main general pension entitlement of all Germans. All pension arrangements by employers consequently represent limited additional pension entitlements. German employers are not obliged to provide an employment pension plan.

ATZ (Altersteilzeit)—early retirement arrangement

ATZ is an early retirement arrangement organized by German employers, Trade/Labor Unions in Germany and the German Government. The ATZ plan is providing additional lifelong pensions to employees who retire before the general retirement age, to compensate for the reduction of the ordinary pension entitlements. The employees are given a choice of retirement age, with lower pension at earlier retirement.

The principle that, during the current employment relationship, the work performed by the employee is equivalent to the remuneration paid by the employer (principle of equivalence) and that there is therefore no impact on the balance sheets does not apply in the case of partial retirement.

The backlog of performance in the block model of ATZ represents an obligation on the part of the employer. The employee has already performed work for which he or she has not yet received any remuneration. For the fee to be paid in the release phase, a provision must be made during the work phase and increased pro rata temporis until the release phase is reached.

The estimated contributions expected to be paid to the German plan during 2025 amount to $0.8 million.

Pension plans in Norway

The main pension arrangement in Norway is a general pension plan organized by the Norwegian Government. This arrangement provides the main general pension entitlement of all Norwegian employees. All pension arrangements by employers consequently represent limited additional pension entitlements.

Norwegian employers are obliged to provide an employment pension plan, which can be organized as a defined benefit plan or as a defined contribution plan. The Company’s subsidiaries located in Norway closed the earlier defined benefit plans in 2008 and are now providing defined contribution plans for all employees.

Defined benefit plan

Employees who were 58 years or older in 2008, when the change to the contribution plan took place, are still in the defined benefit plan, which is a funded plan. There are no longer any active employees in this plan. The estimated contributions expected to be paid to the Norwegian plan during 2025 amount to $0.2 million.

Compensation plan

To ensure that the employees were treated fairly on the change to the contribution plan in 2008, the Company introduced a compensation plan. The basis for deciding the compensation amount is the difference between

F-49

calculated pension capital in the defined benefit plan and the value of the defined benefit plan at the age of 67 years. The compensation amount will be adjusted annually in accordance with the adjustment of the employees’ pensionable income, and accrued interest according to market interest. If the employee leaves the Company voluntarily before the age of 67 years, the compensation amount will be reduced.

AFP—early retirement arrangement

AFP is an early retirement arrangement organized by Norwegian employers, the main Labor Union organization in Norway (LO) and the Norwegian Government. The AFP plan provides additional lifelong pensions to employees who retire before the general retirement age, to compensate for the reduction of the ordinary pension entitlements. The employees are given a choice of retirement age, with lower pension at earlier retirement.

The AFP plan exposes the participating entities to actuarial risk associated with employees of other entities with the result that there is no consistent and reliable basis for allocating the obligation, plan assets and costs to individual participating entities. Sufficient information is not available to use defined benefit accounting, and the AFP plan is accounted for as a defined contribution plan

The following table sets forth the accumulated benefit obligation in Norway and Germany as of December 31, 2024 and 2023:

The components of net periodic cost consisted of the following for the years ended December 31, 2024 and 2023:



Pension benefits	2024		2023
Service cost	$	492	$	199
Interest cost		764		528
Amortization of net actuarial loss		54		102

Net periodic cost	$	1,310	$	829

The defined benefit plans are unfunded and consequently there are no pension plan assets to be disclosed.

As part of the agreement between Akastor and Baker Hughes at the time of the formation of the Company, Akastor is responsible for all pension liabilities accrued and unsettled pension liabilities pre-October 1, 2021. The Company has booked a receivable towards Akastor for its part of the total pension liability. See Note 18— “Related party transactions—Indemnification asset.”

Defined benefit obligation—actuarial assumptions

The following table sets forth the weighted average assumptions used to determine net periodic cost for these plans for the years ended December 31, 2024 and 2023:



	2024				2023
	Norway		Germany		Norway		Germany
Discount rate		4.7%		3.1%		4.4%		3.7%
Expected long-term return on plan assets		—		—		—		—
Interest crediting rate		3.5%		2.6%		0.6%		2.6%

Accumulated other comprehensive income (loss)

The amount recorded before-tax in accumulated other comprehensive income (loss) related to the Company’s defined benefit plans consisted of the following for the years ended December 31, 2024 and 2023:



	2024		2023
Net actuarial loss	$	70	$	(182	)
Net prior service cost	$	—	$	—

The discount rates and other assumptions for Norway in 2024 and 2023 are based on the Norwegian high quality corporate bond rate and recommendations from the Norwegian Accounting Standards Board. It should be expected that fluctuations in the discount rates would also lead to fluctuations in the pension indexations. The total effect of fluctuations in economic assumptions is consequently unlikely to be very significant.

F-51

Assumptions regarding future mortality have been based on published statistics and mortality tables. The current life expectancy after retirement underlying the values of the defined benefit obligation at the reporting date is shown below in years.



	2024				2023
	Norway		Germany		Norway		Germany
Life expectancy of male pensioners after retirement		22.8		20.9		22.7		20.6
Life expectancy of female pensioners after retirement		26.1		24.3		26.0		24.0

Sensitivity analysis

Reasonably possible changes at the reporting date to one of the relevant actuarial assumptions, holding other assumptions constant, would have affected the defined benefit obligation as of December 31, 2024 and 2023. Amounts shown below are for the pension plans in Norway.



2024	Change in defined benefit obligation
Change in actuarial assumptions		Increase		Decrease
Discount rate (1% increase/decrease movement)	$	8,412	$	8,656

For the year ended December 31, 2024, the net change in valuation allowance of $2.8 million was comprised of $3.4 million of additions less $0.9 million of reversals which impacted the effective tax rate. Additional activity included $4.1 million of additions related to an acquisition less $7.5 million of reversals related to reductions in carryforward amounts and $1.9 million of foreign currency translation adjustments. For the year ended December 31, 2023, the net change in valuation allowance of $10.0 million was comprised of $12.0 million of additions less $0.7 million of reversals and $1.3 million of foreign currency translation adjustments.

For the years ended December 31, 2024 and 2023, the Company recognized $0.9 million and $0.7 million, respectively, in net loss benefits in Brazil.

At December 31, 2024, the Company had zero non-U.S. tax credits. Additionally, the Company had $42.5 million of net operating loss carryforwards (“NOLs”), of which approximately $18.1 million will expire between 2030 and 2042, and the remainder can be carried forward indefinitely. The Company also had interest carryforwards of $75.4 million, of which $19.6 million will expire between 2025 and 2030, and the remainder can be carried forward indefinitely.

At December 31, 2023, the Company had approximately $1.4 million of non-U.S. tax credits that will expire between 2024 and 2025 under applicable foreign law. Additionally, the Company had $69.0 million of NOLs, of which approximately $1.9 million will expire between 2035 and 2042, and the remainder can be carried forward indefinitely. The Company also had interest carryforwards of $89.5 million, of which $21.8 million will expire between 2025 and 2030, and the remainder can be carried forward indefinitely.

F-54

The Company operates and is subject to income taxes in multiple jurisdictions. Income tax return periods from 2019 generally remain open for examination in Norway and periods from 2020 generally remain open for examination in other jurisdictions.

As of December 31, 2024, the Company had undistributed earnings of foreign subsidiaries of $77.9 million, which continue to be indefinitely reinvested. The Company makes a determination each period whether to indefinitely reinvest these earnings. If, as a result of these reassessments, the Company distributes these earnings in the future, additional tax liabilities could result. No additional income taxes have been provided for any additional outside basis differences inherent in the Company’s foreign subsidiaries, as these amounts continue to be indefinitely reinvested. Determining the amount of unrecognized deferred tax liability related to any additional outside basis differences in these entities is not practicable.

At December 31, 2024, the Company had approximately $0.8 million of unrecognized tax benefits and does not expect to recognize any significant increases in unrecognized tax benefits during the next twelve-month period. Interest and penalties, in the amount of $0.8 million related to income taxes, are recorded in income tax expense. The total liability recognized for unrecognized tax benefits including interest and penalties is $1.6 million. If recognized, the $0.8 million of unrecognized tax benefits would favorably impact the effective tax rate. During 2024, the aggregate changes in the Company’s total amount of unrecognized benefits are summarized as follows (in thousands):



	Year ended December 31, 2024
Beginning balance	$	—
Increases in unrecognized tax benefits - current year positions		110
Increases in unrecognized tax benefits - prior year positions		661

The Organization for Economic Co-operation and Development has advanced reforms focused on global profit allocation and implementing a global minimum tax rate of at least 15% for large multinational corporations on a jurisdiction-by-jurisdiction basis, known as “Pillar Two.” On December 15, 2022, the European Council formally adopted a European Union directive on the implementation of the plan by January 1, 2024. This is not expected to materially increase the taxes the Company owes and for 2024 HMH is not in scope for implementation of Pillar Two.

17. Commitments and contingencies

Restructuring

The Company has accrued a restructuring provision specific to ESS. The restructuring primarily pertains to a substantial workforce decrease and reorganization, driven by the desire to increase efficiency and flexibility. This provision involves a new organization structure that converts the “Major Projects and Products” division under ESS to “Product and Innovation, Engineering Disciplines and Product Management.” The restructuring is expected to impact 100 individuals, comprising 80 employees in Norway and 20 employees in Germany, and is accrued for a cost of $1.0 million and $1.6 million as of December 31, 2024 and 2023, respectively.

Restructuring costs are contained within other operating expenses (income), net for both 2023 and 2024.

Other

F-55

and tax guarantees to guarantee the Company’s performance as it relates to contracts with customers, contract bidding, customs duties, tax appeals and obligations in various jurisdictions. These arrangements totaled $43.2 million at December 31, 2024. As of December 31, 2024, none of these guarantees either has, or is likely to have, a material impact on the Company’s financial position, results of operations or cash flows as the Company expects to comply with the underlying performance requirements.

Related party transactions

Shareholder Note

On March 17, 2023, the Company entered into a note with Baker Hughes Holdings LLC and Akastor AS (as amended, the “Shareholder Note”) whereby the Company extended credit in the principal amount of $3.45 million to Baker Hughes Holdings LLC and $3.49 million to Akastor AS. The Shareholder Note matures on the earliest to occur of October 1, 2026 or a liquidation event (as defined in the Shareholder Loan Agreement) such as the consummation of HMH Holding Inc.’s initial public offering, and accrues interest at a rate of 8.0% per annum. Subject to certain notice requirements, Baker Hughes Holdings LLC and Akastor AS may voluntarily prepay the Shareholder Note in whole or in part without premium or penalty. There is no right of set-off against the Shareholder Loans.

Baker Hughes

License agreements

On October 1, 2021, in connection with the formation of the Company, the Company entered into worldwide, fully paid, nontransferable and non-sublicensable license agreements with a subsidiary of Baker Hughes giving the Company a limited right to use the terms Vetco^™ and VetcoGray^™ as trademarks on certain products traditionally sold under those trademarks and certain other intellectual property rights relating to certain of Baker Hughes’s intellectual property related to the Subsea Drilling Systems pressure control business that Baker Hughes contributed to the Company at the time of the Company’s formation. The license agreement relating to other intellectual property rights is perpetual in term, and the trademark license agreement relating to use of the terms Vetco^™ and Vetco Gray^™ has an initial five-year term that is renewable by the Company for successive five-year terms as long as the trademarks remain in use for the products traditionally sold under those trademarks.

F-57

Remarketing agreement

On October 1, 2021, in connection with the formation of the Company, the Company entered into a remarketing agreement with Baker Hughes relating to certain BOPs, their associated control systems and other personal property. Such equipment is currently subject to a lease between two unrelated third parties, and the lessor of such equipment has the right to return such equipment to Baker Hughes at the end of the lease term. In the event such equipment is returned to Baker Hughes, the Company has agreed to provide certain services to Baker Hughes with respect to the sale, leasing or remarketing of such equipment in exchange for reimbursement of out-of-pocket costs and expenses.

Transition services agreement

On October 1, 2021, in connection with the formation of the Company, the Company entered into a transition services agreement with Baker Hughes pursuant to which, in exchange for a monthly fee, Baker Hughes would provide the Company with certain transitional administrative, finance and other digital services for a term of up to 12 months. The Company paid a total of $15.8 million to Baker Hughes for the services provided under the transition services agreement. All services under the transition services agreement have now been performed, and there are no outstanding obligations for either party thereunder.

Servicing agreement and long-term incentive offset

On October 1, 2021, in connection with the formation of the Company, the Company entered into a servicing agreement with Baker Hughes pursuant to which the Company agreed to service, administer and collect on certain account receivables owned by Baker Hughes and contributed to the Company in connection with the Company’s formation, and to act as custodian with respect to any related collateral until the account is resolved, a successor is appointed or the parties agree to terminate. The total value of the account receivables pursuant to the servicing agreement as of October 1, 2021 was $54.6 million.

On March 17, 2023, Baker Hughes agreed, as full payment for the approximately $2.5 million in excess long-term incentive liability identified in the post-closing statement relating to the formation of the Company, to assign to the Company all right, title and interest in the aggregate $6.8 million of account receivables remaining to be serviced by the Company under the servicing agreement, including all collections therefrom. The Company also agreed to pay to Baker Hughes by March 31, 2023 approximately $2.3 million as payment for certain property taxes due and payable by the Company.

Akastor

Step Oiltools

In connection with the formation of the Company and pursuant to that certain transaction agreement by and between Akastor and Baker Hughes, dated as of March 2, 2021, as amended on April 27, 2021, September 30, 2021 and September 23, 2022 (the “JV Transaction Agreement”), to which the Company became a party pursuant to a joinder agreement dated as of October 1, 2021, and that certain share purchase agreement by and between Akastor AS and MHWirth AS, dated as of October 1, 2021, Akastor and Baker Hughes agreed that the contribution of one of Akastor’s subsidiaries, Step Oiltools, would be made on a delayed basis until certain Russian regulatory approvals were obtained. Subsequently, Step Oiltools’ business activities were significantly impacted by the Russian invasion of Ukraine, and it was decided that Step Oiltools would be liquidated. The parties agreed to cease seeking regulatory approval for the sale and to settle a seller’s credit in the amount of approximately $16.0 million, payable by Akastor to the Company, in exchange for Akastor transferring to the

F-58

Company the proceeds from the Step Oiltools liquidation. The Company’s management has assessed the expected net proceeds from the liquidation of Step Oiltools during 2022 and does not believe that such proceeds would yield net cash flows equal to the original seller’s credit receivable from Akastor and, as such, recorded a one-time charge of $16.0 million in 2022. The fair value of the receivable has been remeasured to zero as of December 31, 2024 and 2023.

Payment of pension benefits

Pursuant to the JV Transaction Agreement, as part of its contribution to the Company at the time of the Company’s formation, Akastor agreed to pay certain carved-out pension liabilities existing in MHWirth AS prior to its contribution to the Company until such time as Akastor owns less than 5% of the Company’s equity interests, at which time Akastor will be obligated to pay all estimated remaining and unpaid pension costs. The Company estimated the value of such remaining and unpaid pension costs to be $18.5 million and $20.2 million as of December 31, 2024 and 2023, respectively, and the Company recorded a receivable of $19.9 million and $21.9 million as of December 31, 2024 and 2023, respectively, related to such pension payments from Akastor, which is reduced in line with pension payments to former employees in 2024 and 2023. The difference between unpaid pension costs and receivable is due to the timing of payments made to pensioners and pension payments received from Akastor by the Company.

Financial guarantees

As of December 31, 2024, Akastor had issued financial guarantees of approximately $35.1 million in favor of MHWirth AS, a wholly owned subsidiary of the Company, for fulfillment of certain lease obligations and performance under certain operational support frame agreements.

Transition services agreement

On October 1, 2021, in connection with the formation of the Company, the Company entered into a transition services agreement with Akastor pursuant to which, in exchange for an hourly fee, Akastor would provide the Company with certain transitional finance, IT and treasury services for a term that concluded at the end of 2023. The Company paid a total of $0.4 million to Akastor for the services provided under the transition services agreement. All services under the transition services agreement have now been performed, and there are no outstanding obligations for either party thereunder.

Indemnification asset

The Company obtained an indemnification asset that is related to the pension liabilities Akastor sold to the Company. As a result, Akastor is contractually obligated to indemnify the Company for that specific liability. An asset was recognized at the same time and measured using the same measurement basis as the liability. This ensured that both the asset and the liability were measured on a consistent basis using similar assumptions.

After initial recognition, an indemnification asset continues to be measured based on the assumptions used to measure the related liability, subject to management’s assessment of collectability of the asset, limited to the amount of the liability to which it relates. As the receivable offsets the liability movement and thus reflecting that the Company is being compensated for this by Akastor, the pension receivable is also remeasured at each reporting date. Therefore, the receivable is accounted for in a similar way in the consolidated statements of income. The indemnification asset is included in related party notes receivable—current and related party notes receivable on the consolidated balance sheets.

19. Segment information and geographic data

Operating segments are defined as components of an entity for which separate financial information is available and evaluated on a regular basis by the Chief Operating Decision Maker (“CODM”) to allocate resources and assess performance. As of December 31, 2024 and December 31, 2023, the Company had two operating segments, ESS and PCS. The Company has identified its reportable segments based on the nature of the products and services, markets served and pricing and go-to-market strategies.

•

ESS is a supplier of drilling solutions and complete topside drilling packages and services to both onshore and offshore oil and gas customers. Key product offerings consist of overhaul, equipment installation and commissioning, services account management, 24/7 technical support, logistics, engineering upgrades, spare parts supply and training and condition-based maintenance. The ESS segment is derived from the acquisition of MHWirth AS.

•

PCS is a supplier of integrated drilling products and services. Key product offerings consist of BOP systems, controls and drilling riser equipment, spare parts supply for rig operations and maintenance programs, overhaul and recertification and reactivation of rigs and technical and operational rig support. The PCS segment is derived from the acquisition of Subsea Drilling Systems.

In addition to its reportable segments, the Company has corporate operations (Headquarters) which include general corporate expenses. Headquarters includes other items necessary to reconcile the reportable segments to the Company’s total amounts.

The CODM, who is the company’s Chief Executive Officer, uses segment operating income as the primary financial measure to evaluate segment performance. Segment operating income is defined as income before taxes, net other operating expenses (income), net foreign currency gain/(loss), net other non-operating income (loss), and net interest income (expense). Inter-segment pricing is determined on an arm’s length basis. The CODM uses segment operating income in the budget and forecasting process and to monitor budget versus actual results, which are used in assessing the performance of the segments and to allocate resources to the segments.

Segment assets are not reported to, or used by, the CODM to allocate resources to or assess performance of the Company’s segments. During the year ended December 31, 2024, one customer accounted for 18.2% of the Company’s revenues, which is included in both ESS and PCS revenue. There were no customers that individually accounted for more than 10% of the Company’s consolidated revenue during the year ended December 31, 2023.

The accounting policies of the reportable segments are the same as described under Note 1—“Basis of presentation and summary of significant accounting policies.”

For purposes of calculating earnings per share, Class A ordinary shares and Class B ordinary shares are identical. Therefore, the Company has calculated basic earnings per share on the basis of 200 shares. Basic earnings per ordinary share is calculated by dividing the net income to the Company during the period by the weighted average number of ordinary shares outstanding during the same period. There are no adjustments required to be made to net income or the ordinary shares outstanding for purposes of computing basic and diluted earnings per share.

21. Subsequent events

The Company evaluated subsequent events through March 17, 2025, the date that the consolidated financial statements were available to be issued.

In January 2025, the Company announced a restructuring plan primarily focused on the reorganization of facilities in Horten and Fornebu, Norway and global workforce reductions. The restructuring will optimize the Company’s global indirect headcount and rationalize its footprint.

On March 10, 2025, DNB Bank ASA agreed as agent under the Revolver to amend certain terms of the Revolver to permit implementation of the corporate reorganization and the listing of HMH Holding Inc.’s Class A common stock on Nasdaq, and the documentation formally implementing the same became effective as of March 11, 2025.

Notes to condensed consolidated financial statements (unaudited)

1. Basis of presentation and summary of significant accounting policies

Description of business

HMH Holding B.V. (“HMH,” the “Company,” “we” or “our”) is a leading global provider of offshore and onshore drilling equipment and services.

Basis of presentation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S.” and such principles, “U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Certain information and note disclosures normally included in the Company’s annual financial statements have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2024.

In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, which are necessary for the fair statement of the condensed consolidated balance sheets, statements of income, statements of comprehensive income, statements of change in shareholders’ equity and statements of cash flows for these interim periods. The results for the interim period are not necessarily indicative of the results that may be expected for a full year.

The unaudited condensed consolidated financial statements include the accounts of the Company and all of its subsidiaries and affiliates that it controls or variable interest entities for which the Company has determined it is the primary beneficiary. All intercompany accounts and transactions have been eliminated.

In the notes to the unaudited condensed consolidated financial statements, all dollar amounts in tables are in thousands of dollars unless otherwise indicated. Certain columns and rows in the financial statements and notes thereto may not add due to the use of rounded numbers.

Certain amounts in prior periods have been reclassified to conform with current period presentation.

Summary of significant accounting policies

Refer to Note 1—“Basis of presentation and summary of significant accounting policies” to the Company’s audited consolidated financial statements for the year ended December 31, 2024, included elsewhere in this prospectus.

Concentration risk

The Company had three customers that accounted for approximately 14.4%, 12.3% and 11.9%, respectively, of total revenue for the three months ended March 31, 2025, and two customers that accounted for approximately 20.3% and 10.6%, respectively, of total revenue for the three months ended March 31, 2024.

F-69

The Company had one customer that accounted for approximately 11.2% of current accounts receivable, net as of March 31, 2025, and one customer that accounted for approximately 10.4% of current accounts receivable, net as of December 31, 2024.

The Company expects to maintain its relationships with these customers.

New accounting standards to be adopted

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 provide for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 is effective for the Company prospectively to all annual periods beginning after December 15, 2025. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its disclosures.

In November 2024, the FASB issued ASU No. 2024-03, “Disaggregation of Income Statement Expenses (Subtopic 220-40).” The ASU requires public entities to disaggregate, in a tabular presentation, certain income statement expenses into different categories, such as purchases of inventory, employee compensation, depreciation and intangible asset amortization. The guidance is effective for fiscal years beginning after December 15, 2026, with early adoption permitted, and may be applied retrospectively. The Company is currently evaluating the impact of adopting the new ASU on its consolidated financial statements and related disclosures.

2. Business combinations

Drillform Technical Services Ltd.

On July 17, 2024, Hydril PCB Canada Inc., a wholly-owned subsidiary of the Company, completed its acquisition of all of the issued and outstanding shares of Drillform Technical Services Ltd. (“Drillform”) for a total purchase price of $24.7 million, consisting of $21.0 million in cash and $3.7 million in contingent consideration. Drillform holds a portfolio of patents and intellectual property related to equipment used in the handling of drill pipe during drilling operations and has a significant installed base of automated floor wrenches and catwalks. Drillform is based in Alberta, Canada and has facilities in Tulsa, Oklahoma and Abu Dhabi, United Arab Emirates. The Company accounted for the transaction as a business combination and allocated the total

F-70

purchase price to assets acquired, liabilities and contingent consideration assumed based on their fair values at the date of acquisition. The purchase price allocation as of the date of acquisition was based on a preliminary valuation and is subject to revision as more detailed analyses are completed and additional information about the fair value of assets acquired and liabilities assumed becomes available.

The following table provides the preliminary allocation of the purchase price to major classes of assets and liabilities as of the acquisition date. The goodwill reflected below increased by $2.4 million from the original preliminary purchase price allocation as a result of measurement period adjustments related to warranty liabilities.



Assets
Cash and cash equivalents	$	1,377
Accounts receivable		836
Inventory		3,043
Prepaid expenses and other current assets		110

Total current assets		5,366

Total debt and leases		2
Contingent consideration		3,700

Total liabilities	$	11,803
Equity consideration	$	21,000
Goodwill	$	15,998

The following table summarizes the fair value of acquired identifiable intangible assets as of the date of acquisition:


Development costs⁽¹⁾	$	6,000
Customer relationships⁽¹⁾		5,000

Total acquired intangible assets	$	11,000

(1)

The weighted-average amortization period for developed technology and customer relationships are 5 years and 2 years, respectively.

The contingent consideration consists of deferred payments by the Company to the acquiree’s prior equity and debt holders for three years, contingent on meeting the prescribed realized sales price and margin targets for certain types of units sold. The Company estimated the fair value of the contingent consideration using a probability-weighted discounted cash flow method under the income approach. The Company considered a range of outcomes, with the maximum being $12.0 million, and determined the most likely amount of undiscounted contingent consideration is $4.7 million.

F-71

3. Goodwill

Changes in the carrying amount of goodwill were as follows:



	December 31, 2024		Other		March 31, 2025
Goodwill	$	300,939	$	2,245	$	303,184

The measurement periods for the valuation of assets acquired and liabilities assumed end as soon as information on the facts and circumstances that existed as of the acquisition dates becomes available, but do not exceed 12 months. Adjustments in purchase price allocations may require a change in the amounts allocated to goodwill during the periods in which the adjustments are determined.

Any change in the goodwill amounts resulting from foreign currency translations and purchase accounting adjustments are presented as “Other” in the table above. For the three months ended March 31, 2025, goodwill increased $2.4 million as a result of measurement period adjustments, offset by a reduction of $0.2 million related to foreign currency translation. See Note 2—“Business combinations” for a discussion of purchase accounting adjustments.

4. Inventories

Inventories, net of reserves of $102.0 million and $105.4 million as of March 31, 2025 and December 31, 2024, respectively, consisted of the following as of March 31, 2025 and December 31, 2024:



	March 31, 2025		December 31, 2024
Stock of raw materials	$	66,092	$	26,354
Goods under production (work in progress)		41,513		45,585
Finished goods		173,666		208,018

Inventories, net	$	281,271	$	279,957

For the three months ended March 31, 2025, the Company recorded inventory write-downs of $1.9 million. There were no inventory write-downs for the three months ended March 31, 2024.

F-72

5. Financial instruments

The following tables set forth the Company’s financial instruments that are measured at fair value on a recurring basis by level within the fair value hierarchy as of March 31, 2025 and December 31, 2024:

The carrying value of cash and cash equivalents, current receivables, accounts payables and accrued expenses approximates fair value based on the short-term nature of these accounts.

Cash flow hedges

The Company uses cash flow hedging primarily to mitigate the effects of foreign exchange rate changes on future transactions denominated in foreign currencies. Accordingly, the vast majority of the Company’s derivative activity in this category consists of forward currency exchange contracts. Changes in the fair value of cash flow hedges are recorded in the hedge reserve in accumulated other comprehensive income (“AOCI”) and are recorded in earnings in the period in which the hedged transaction occurs. See the condensed consolidated statements of changes in shareholders’ equity above for further information on activity in AOCI for cash flow hedges. The maximum term of cash flow hedges is under 24 months as of both March 31, 2025 and December 31, 2024.

F-73

in the projects. Gains and losses on forward foreign exchange contracts are recognized in other comprehensive income and reported as measurement adjustments within AOCI in equity until they are recognized in the consolidated statements of income in the period or periods during which the hedged transactions affect the consolidated statements of income. If the forward foreign exchange contract is rolled due to a change in timing of the forecasted cash flow, the settlement effect is included in contract assets or contract liabilities.

Derivative financial assets and liabilities are included in the other current assets and other current liabilities on the consolidated balance sheet.

The table below presents the fair value of the derivative financial instruments and a maturity analysis of the derivatives cash flows. Valuation techniques and inputs of forward contracts are based on the quoted forward exchange rate.

Lender provided a credit line in an aggregate principal amount of up to Chinese renminbi (RMB) 10.0 million. The Credit Line in China has an effective period from March 27, 2025 to March 26, 2026. The borrowing length for each withdrawal is one year.

Borrowings under the Credit Line in China bear interest at the compounded reference rate, which is the applicable China Loan Prime Rate minus margin 0.4%. Interest is paid quarterly in the last month of each quarter. There is no quarterly commitment fee nor guarantee requirement based on the Company’s financial status.

The fair value was determined using a market approach based on observable inputs. For the remaining debt instruments, the book values of each instrument approximate its respective carrying amount, as these interest rates are variable in nature and are reflective of market rates.

The tax provision for the three months ended March 31, 2025 and 2024 was $5.3 million and $4.1 million, respectively. The increase in the tax provision was primarily attributable to a change in the Company’s geographic mix of revenues.

The effective tax rate for the three months ended March 31, 2025 and 2024 was 47.2% and 32.8%, respectively. The Company’s effective tax rates for the three months ended March 31, 2025 and 2024 were negatively

F-80

impacted by the changes in valuation allowance related to losses in certain jurisdictions for which the Company cannot currently recognize a tax benefit.

In the normal course of business with customers, vendors and others, the Company has issued various bank guarantees, such as advance payment guarantees, surety bonds, performance guarantees, bid bonds, customs and tax guarantees to guarantee the Company’s performance as it relates to contracts with customers, contract bidding, customs duties, tax appeals and obligations in various jurisdictions. These arrangements totaled $49.3 million at March 31, 2025. As of March 31, 2025, none of these guarantees either has, or is likely to have, a material impact on the Company’s financial position, results of operations or cash flows as the Company expects to comply with the underlying performance requirements.

17. Segment information

Operating segments are defined as components of an entity for which separate financial information is available and evaluated on a regular basis by the Chief Operating Decision Maker (“CODM”) to allocate resources and assess performance. As of March 31, 2025 and March 31, 2024, the Company had two operating segments, ESS and PCS. The Company has identified its reportable segments based on the nature of the products and services, markets served and pricing and go-to-market strategies.

•

F-82

engineering upgrades, spare parts supply, training and condition-based maintenance. The ESS segment is derived from the acquisition of MHWirth AS.

•

In addition to its reportable segments, the Company has corporate operations (Headquarters) which include general corporate expenses. Headquarters includes certain corporate stewardship items discussed below necessary to reconcile the reportable segments to the Company’s total amounts.

The CODM, who is the company’s Chief Executive Officer, uses segment operating income as the primary financial measure to evaluate segment performance. Segment operating income is defined as income before taxes (excluding certain corporate stewardship costs which are not allocable to the segments, such as legal, certain corporate finance functions and centrally managed initiatives, other non-operating items, and depreciation and amortization related to certain long-lived assets, including the headquarters office space), net other operating expenses (income), net foreign currency gain/(loss), net other non-operating income (loss), and net interest income (expense). Inter-segment pricing is determined on an arm’s length basis. The CODM uses segment operating income in the budget and forecasting process and to monitor budget versus actual results, which are used in assessing the performance of the segments and to allocate resources to the segments. Segment assets are not reported to, or used by, the CODM to allocate resources to or assess performance of the Company’s segments.

The accounting policies of the reportable segments are the same as described under Note 1—“Basis of presentation and summary of significant accounting policies.”

The following tables present segment performance for the three months ended March 31, 2025 and 2024:

18. Earnings per share

For purposes of calculating earnings per share, Class A ordinary shares and Class B ordinary shares are identical. Therefore, the Company has calculated basic earnings per share on the basis of 200 shares. Basic earnings per ordinary share is calculated by dividing the net income attributable to the Company during the period by the weighted average number of ordinary shares outstanding during the same period. There are no adjustments required to be made to net income or the ordinary shares outstanding for purposes of computing basic and diluted earnings per share.

In accordance with Section 102(b)(7) of the DGCL, our amended and restated certificate of incorporation that will be in effect at the completion of this offering will provide that no director or officer shall be personally liable to us or any of our stockholders for monetary damages resulting from breach of their fiduciary duty as directors or officers, as applicable, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as it now exists or may hereafter be amended. The effect of this provision of our amended and restated certificate of incorporation will be to eliminate our rights and those of our stockholders (through stockholders’ derivative suits on our behalf) to recover monetary damages against a director or officer for breach of the fiduciary duty of care as a director or officer, including breaches resulting from negligent or grossly negligent behavior, except, as restricted by Section 102(b)(7) of the DGCL. However, this provision will not limit or eliminate our rights or the rights of any stockholder to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of a director’s or officer’s duty of care. Any amendment, repeal or modification of provisions of our amended and restated certificate of incorporation that purports to limit the

II-1

liability of a director or officer will be prospective only and will not affect any limitation on liability of a director or officer, as applicable, for acts or omissions occurring prior to the date of such amendment, repeal or modification.

Indemnification

Section 145 of the DGCL permits a corporation, under specified circumstances, to indemnify its directors, officers, employees or agents against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by them in connection with any action, suit or proceeding brought by third parties by reason of the fact that they were or are directors, officers, employees or agents of the corporation, if such directors, officers, employees or agents acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reason to believe their conduct was unlawful. In a derivative action, i.e., one by or in the right of the corporation, indemnification may be made only for expenses actually and reasonably incurred by directors, officers, employees or agents in connection with the defense or settlement of an action or suit, and only with respect to a matter as to which they shall have acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made if such person shall have been adjudged liable to the corporation, unless and only to the extent that the court in which the action or suit was brought shall determine upon application that the defendant directors, officers, employees or agents are fairly and reasonably entitled to indemnity for such expenses despite such adjudication of liability.

We intend to enter into indemnification agreements, to be effective upon the completion of this offering, with our directors and officers containing provisions that are in some respects broader than the specific indemnification provisions contained in the DGCL. The indemnification agreements will require us, among other things, to indemnify our directors and officers against certain liabilities that may arise by reason of their status or service as directors or officers and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified. We also intend to enter into indemnification agreements with our future directors and officers.

We intend to maintain liability insurance policies that indemnify our directors and officers against various liabilities, including certain liabilities arising under the Securities Act or the Exchange Act that may be incurred by them in their capacity as such.

The rights to indemnification and advancement of expenses will not be deemed exclusive of any other rights which any person covered by our amended and restated certificate of incorporation or the indemnification agreements may have or hereafter acquire under law, our amended and restated certificate of incorporation, our amended and restated bylaws that will be in effect at the completion of this offering, an agreement, vote of stockholders or disinterested directors, or otherwise.

Our amended and restated bylaws will include provisions relating to advancement of expenses and indemnification rights consistent with those to be set forth in our amended and restated certificate of incorporation and the indemnification agreements. In addition, our amended and restated bylaws will provide for the right of an indemnitee to bring a suit in the event a claim for indemnification or advancement of expenses is not paid in full by us within a specified period of time. Our amended and restated bylaws will also permit us to purchase and maintain insurance, at our expense, to protect us and any person who is or was serving as a director, officer, employee or agent of our corporation or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, other enterprise or non-profit entity, including with respect to an employee benefit plan, against any expense, liability or loss

II-2

asserted against them and incurred by them in such capacity, or arising out of their status as such, whether or not we would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Any repeal or modification of the provisions of our amended and restated bylaws affecting indemnification rights will not adversely affect any right or protection thereunder in respect of any proceeding (regardless of when such proceeding is first threatened, commenced or completed) arising out of, or related to, any act or omission occurring prior to the time of such repeal or modification.

Under the underwriting agreement, the underwriters are obligated, under certain circumstances, to indemnify directors and officers of the registrant against certain liabilities, including liabilities under the Securities Act. Reference is made to the form of underwriting agreement filed as Exhibit 1.1 to this registration statement.

Financial Statement Schedules

See the index to the financial statements included on page F-1 for a list of the financial statements included in this registration statement.

Item 17. Undertakings

The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

(1)

For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2)

For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
