A Stable Foundation Our company is built on the strength of our legacy coal mining operations. Through North American Coal®, we operate surface mines that are the exclusive suppliers to adjacent power plants and related facilities under multi-decade contracts that generate stable and reliable recurring cash flows. This long- term approach and the operational expertise embedded within our coal business have shaped the business model we operate under today. A Distinctive Business Model Our distinctive business model is anchored by multi-year customer relationships. We work as a deeply integrated partner within our customers’ operations, often under arrangements that span decades. These partnerships generate predictable long-term income and cash flows, which we selectively Leveraging decades of coal mining expertise, North American Mining started over 30 years ago with one customer in South Florida. We now operate over 20 locations across the United States. reinvest to support continued growth. We pursue opportunities that fit our disciplined underwriting criteria, seeking long-term opportunities that match our skills with financially strong and like-minded customers, along with modest maintenance capital requirements. This model enables us to prioritize expansion via patient long-term value creation over shorter-term approaches. Our long-term perspective allows us to pursue higher return opportunities that others with shorter time horizons might overlook. Expanding the Platform Over the last 113 years we have developed operational expertise and capabilities, backed by a strong reputation, that have allowed us to evolve from a single- industry focused company to a diversified portfolio of natural resource businesses. North American Coal has been mining coal for over 100 years, and delivering coal to our longest standing customer-owned power plant since 1978. We know what it takes to build successful partnerships that will last decades. We are highly skilled surface mine operators with a consistent track record of operational excellence. Our Contract Mining segment leverages our legacy coal mining skills and capabilities to perform integrated mining services for top aggregates and industrial minerals producers. North American Mining® began in South Florida over 30 years ago using our coal mining expertise to mine limestone for an aggregates customer. This business model has now expanded across regions, materials and equipment types. In Nevada, we are developing and will operate a lithium mine adjacent to our customer’s processing facility, part of the world’s largest proven lithium reserve. While this represents our entry into the lithium sector, the model is familiar: long-term partnership, disciplined investment and predictable returns over time. Growth is often organic as existing 35425_NACCO_Rev0_3-18.pdf 5 2026/3/10 10:41˜AM

Mitigation Resources provides stream and wetland mitigation solutions and broader ecological reclamation and restoration services. It develops and manages mitigation banks and projects that create environmental mitigation credits and provides permittee-responsible mitigation work. attractive risk-adjusted returns and predictable cash flows. We target projects offering returns in excess of our 10% hurdle rate. Every year, each of our businesses adds new long-term projects that will serve us for years to come, enhancing already strong recurring cash flows. Longer- term projects are supplemented with shorter-term value creation projects that allow us to more fully capitalize on our investments in people and equipment and generate additional income. Each new relationship, contract and investment enhances our core skills and core competencies, expands our opportunities for growth, and generates recurring cash flows that reinforce the cycle of value creation we have built. We aim to drive growth and higher returns by scaling operations and expanding our footprint. As we begin to harvest returns from prior investments, these returns will support improvements in operating profit and EBITDA while enhancing customers invite us to help them at other locations. This segment’s contracts generate attractive returns, strengthened by long- term relationships and minimal maintenance needs. Our Minerals and Royalties platform grew from legacy natural gas assets that we have held for decades. Catapult Mineral Partners® manages these legacy holdings, as well as a growing portfolio of investments in high- quality mineral and royalty interests. We now hold positions in established areas including the Permian, Haynesville and Appalachian basins. Since 2020, we’ve deployed over $105 million of capital in this segment, maintaining a patient, value- oriented approach aimed at long- term upside. We anticipate these assets will generate strong cash flows for decades to come. Our Ecological Solutions business, Mitigation Resources of North America®, applies NACCO’s deep environmental management expertise to provide natural resource restoration and reclamation services, as well as stream and wetland mitigation solutions. Mitigation Resources is successfully leveraging its strong reputation and clear competitive strengths to expand into additional restoration and reclamation markets. While performance may vary period to period due to customer demands and permit and project timing, results are expected to become more consistent over time as this business matures and expands. While existing long-term contracts and investments in each of our businesses provide clear visibility into future performance, we remain focused on securing new opportunities to further accelerate future growth. Capital Allocation and Sustainable Value Creation Our approach to capital allocation has remained consistent over time. We deploy capital only when projects meet our disciplined investment criteria: long-term contracts, stable counterparties, 35425_NACCO_Rev0_3-18.pdf 6 2026/3/10 10:41˜AM
7ANNUAL REPORT Bringing Natural Resources to Life returns on invested capital. We are targeting $150 million of annual EBITDA within a five- to seven-year timeframe. We believe that we can do so with a conservative approach to our balance sheet while returning capital to shareholders through dividends and, at times, open market share repurchases. Looking Ahead As we enter 2026, NACCO is well- positioned to navigate growth with agility and purpose. Our strategies are not shaped by short-term trends. We balance stability with opportunity while maintaining a perspective on growth that is anchored in our proven long-term business model and guided by a commitment to value creation. We are not speculative, cyclical or trend-dependent. We are a unique domestic natural resources company focused on work that is essential to the foundations of American industry: electricity generation, manufacturing, construction and development, and the production of hydro- carbons, industrial minerals and chemicals. We are committed to operating as a trusted partner to our customers, an engaged employer for our people and a responsible steward of the environment and the communities where we live and work. In closing, I would like to note, with sadness, the death of our board member, Roger Rankin. As a grandson of NACCO’s founder, Roger had a deep and long-standing commitment to and passion for the Company. His contributions will be greatly missed. Lori Robinson stepped down from our Board in May 2025. I would like to thank her for her five years of service. We were privileged to have her on our Board.

8 NACCO INDUSTRIES Bringing Natural Resources to Life Our Utility Coal Mining segment, operated by North American Coal®, is the foundation of our company. This segment’s unique business model is anchored by a stable portfolio of long-term mining contracts that eliminate any exposure to spot coal market price volatility and generate dependable recurring cash flows. We operate four mine- mouth surface coal mines that provide fuel for power generation companies. Each of our mines is the exclusive fuel provider to its adjacent power plant or synfuels facility, and we are contractually designated as the exclusive coal supplier, providing substantial protection from competitive pressures. Strategic Importance and Market Position The Utility Coal Mining business operates in an environment that is experiencing strong growth in power demand needed to fuel the tech-driven future. According to the U.S. Energy Information Administration, electricity consumption is expected to continue to increase in 2026 and 2027. Under the current administration, the regulatory environment for coal-fired power generation has improved significantly. As growth in data- intensive industries accelerates, our customers provide the reliable and affordable 24/7 base-load power generation required to meet this increasing demand. Operational Integration and Competitive Advantages Our business model is purposely built for durability and resilience. Each of our mines is uniquely integrated into its customer’s operations. The coal mines and the plants they serve function as a single, interdependent system. Each facility was designed to utilize the specific coal characteristics from its dedicated mine, creating optimal operational efficiency. As a result, our operations are embedded within our customers’ daily activities, supporting the reliable delivery of affordable base-load electricity. This deep integration creates interdependent operations and ensures collaborative management for sustained success. This embedded operational structure, combined with long-term exclusive supply agreements and proven multi- decade track records, creates durable competitive advantages. We believe our customers are stable, and their power plants are essential providers of affordable and reliable base-load power. With an operating history dating back to 1913, our Utility Coal Mining business continues to play a vital role in meeting America’s growing demand for reliable and affordable electricity, while providing the stability necessary to support the Company’s long-term growth strategy. These attributes have enabled the segment to generate consistent earnings and cash flow for decades, providing the financial foundation for NACCO’s expansion into additional natural resource platforms.

9ANNUAL REPORT Bringing Natural Resources to Life Our Operating Models Coteau’s Freedom Mine, the Falkirk Mine and the Coyote Creek Mine Income is generated by fee-based management contracts that eliminate exposure to spot coal market price volatility. Management fees are paid per ton of coal delivered. These operations provide annuity-like earnings that generate steady profit and cash flow over the long term. For these operations, our customers pay all operating costs, including reclamation, and our management fees adjust in line with broad economic indicators such as the Consumer Price Index or the Producer Price Index. Our income is based on the amount of coal delivered, and our fee adjusts for periodic changes in these economic indicators. Because this unique management-fee contract structure limits our downside risk and requires minimal capital investment by us, these entities are not consolidated within our financial statements. Rather, our service-fee income from these mining operations is reported as Earnings of Unconsolidated Operations in our income statement. We also believe this contract structure is the most efficient for our customers and affords them the lowest possible fuel cost for their plants. Mississippi Lignite Mining Company’s Red Hills Mine Profitability at Mississippi Lignite Mining Company is affected by plant availability, dispatch and customer demand for coal, changes in the indices that determine sales price and actual costs incurred. The coal price adjusts monthly based on a contractually agreed formula designed to track coal production costs over time. We have invested capital in this mine and are responsible for all operating costs, capital requirements and final mine reclamation. Our coal mining operations are embedded within our customers’ daily activities. At the Falkirk Mine, above, coal is loaded into a haul truck, providing reliable fuel for the Coal Creek Station power plant, while below, a dragline efficiently removes overburden, improving access to lignite reserves. 35425_NACCO_Rev0_3-18.pdf 9 2026/3/10 10:41˜AM

11ANNUAL REPORT Bringing Natural Resources to Life Our Contract Mining segment, operated by North American Mining®, represents NACCO’s platform for growth and diversification of mining activities outside of the thermal coal industry. This business is a leading provider of a broad range of specialized, long-term contract mining services for producers of industrial minerals and products. Our operational expertise in coal mining provided the foundation for developing this business as a provider of value- added contract mining services. We provide precision mining services that integrate directly into our customers’ operations, mainly at independently owned mines and aggregates quarries. This business model allows customers to focus on their areas of expertise: materials handling and processing, product sales and distribution, while we focus on our area of expertise: mining. Business Model and Competitive Position We provide comprehensive or highly targeted mining services based on each customer’s needs, operating under multi- year contracts that align our interests with those of our customers. Depending on project requirements, contracts may be structured on a fee-for-service basis or include upfront capital investment, with contract terms and economics designed to generate long-term returns on capital, with modest sustaining capital needs. This integrated, partnership- based model has enabled us to establish strong relationships with several of the top ten aggregates producers in the United States. Many customers have relied on us for decades, including a long- standing Florida aggregates relationship that has been in place since 1995. As customers expand organically or through acquisitions, we have seen an increase in requests to extend our services to these new operations, providing a significant source of organic growth for our business. This dynamic has contributed to an accelerating pace of geographic and mineral expansion in recent years. Specialized Mining Capabilities North American Mining is a leading U.S. operator of draglines, which are large, complex machines used to move materials in a highly North American Mining uses draglines, such as the one shown above at a quarry in central Florida, to extract aggregates and industrial minerals, including material submerged below the water table.

12 NACCO INDUSTRIES Bringing Natural Resources to Life Bringing Natural Resources to Life efficient, low-cost way. We use draglines to extract aggregates and industrial minerals, including material submerged below the water table. We believe NACCO operates more draglines than any other provider in the United States, with a fleet that has grown significantly over the past decade. North American Mining alone operates over 30 draglines, supporting operations primarily in the Florida aggregates market, while continuing to expand into new regions. Our expertise in dragline operation and maintenance provides customers with a cost-effective and highly efficient mining solution. Our scale and expertise led us to partner with MTECK, a Dutch manufacturer, to develop the next generation of all-electric draglines, offering efficiency and productivity advantages over conventional machines. These draglines incorporate operational insights from our experienced mining team, resulting in machines optimized for field performance. Our decades of experience allow us to support a wide range of mining applications across aggregates, limestone, sand and gravel, and other industrial minerals. Geographic and Mineral Expansion Our geographic and mineral expansion over the past decade demonstrates that our core mining expertise is applicable beyond traditional markets, geographies and equipment types, covering a large and growing addressable market. Currently, we operate at over 20 mining locations, up from 6 quarries in 2015. We continue to expand geographically and into new mineral applications beyond our core aggregates business. A dragline moves aggregates at a customer site. Lithium and Critical Minerals Platform North American Mining’s capabilities also extend beyond industrial minerals into critical minerals. We are the exclusive miner for the Thacker Pass lithium project in northern Nevada. Sawtooth Mining, a North American Mining subsidiary, will provide comprehensive mining services at Thacker Pass, which is owned by a joint venture led by Lithium Americas Corp. This project is developing the largest measured lithium reserve and resource in the world and is expected to play a meaningful role in strengthening the domestic U.S. supply of this critical mineral. We are currently providing civil construction services for the lithium processing plant erection site and are preparing to construct the lithiummine adjacent to the processing plant. This project is providing stable income during construction and is expected to contribute enhanced operating income and long-term cash flows once lithium production commences, which is targeted for late 2027. Equipment at Thacker Pass moves material at the plant construction site. 35425_NACCO_Color_ACG.indd 12 2026/3/11 2:0 M
13ANNUAL REPORT Bringing Natural Resources to Life Strategic Expansion: Everglades Restoration Project In October 2025, North American Mining was awarded a newmulti-year contract in Palm Beach County, Florida, to provide dragline excavation services for a U.S. Army Corps of Engineers project in the Florida Everglades. This represents a strategic expansion of our services beyond aggregates into large-scale civil infrastructure projects. It also provides an opportunity to showcase the efficiency and environmental advantages of our new and fully AC-electric-drive MTECK draglines – a key factor in our selection for the project. North American Mining will provide excavation services to move more than 25 million tons of material needed to construct a 17.75-mile embankment dam and various spillways as part of this project. A surface miner at a cement plant quarry loads material onto a haul truck. Recent years have brought successful execution of new contracts and extensions of existing contracts as we capitalize on our expertise. The Contract Mining segment is poised to benefit from additional revenue streams and economies of scale as operations under new contracts begin in 2026, including work at a new Arizona quarry and in support of a large-scale civil works project in Florida. Growth Outlook We continue to expand North American Mining’s portfolio of long-term contracts, supported by a robust pipeline of potential opportunities. New contracts and contract extensions are central to the business’s organic growth strategy, with each new contract expected to contribute operating profit and EBITDA through multi- year terms that can span a decade or more. Through its disciplined capital approach, long-term customer partnerships and scalable operating model, the Contract Mining segment is positioned as a key pillar of NACCO’s strategy to generate durable growth and long- term value creation. 35425_NACCO_Rev0_3-18.pdf 13 2026/3/10 10:41˜AM
14 NACCO INDUSTRIES Bringing Natural Resources to Life Bringing Natural Resources to Life The Minerals and Royalties business, led by Catapult Mineral Partners®, acquires and promotes the development of mineral interests and other related investments. Mineral interests retained from our historical coal mining operations and expertise developed over decades in natural resources provided the foundation to develop this business. Investment Strategy and Competitive Positioning Catapult has built a high- quality, diversified portfolio of oil and gas mineral and royalty interests and investments spread across established producing basins in the United States, including the Permian, Haynesville and Appalachian. Our asset base consists of wells that generate current cash flow, as well as undeveloped and partially developed acreage that provides meaningful long-term upside. This multi-basin, multi-operator diversification strategy mitigates risk and broadens opportunities to generate attractive long-term returns on invested capital. As of December 31, 2025, the portfolio includes approximately 64,000 net royalty acres and thousands of gross wells, spanning a wide range of operators, basins and development profiles. Catapult employs a disciplined investment approach that leverages analytical capabilities. The team utilizes a data-driven methodology that integrates public and proprietary data to forecast production profiles and future development potential. A defining feature of our strategy is our long- term investment horizon, allowing the business to identify and acquire mineral interests in productive basins at valuations that we believe offer attractive risk-adjusted returns. Unlike many market participants that focus primarily on near-term production, Catapult actively pursues acquisition packages that include assets that may not be developed for several years. This patient approach will deliver returns over a longer horizon as these minerals are developed over time. Capital Deployment Discipline and Business Model The Minerals and Royalties business is supported by a flexible capital deployment model that generally targets approximately $20 million of annual investment; however, actual spending is adjusted based on opportunities and market conditions. Capital is not required to be deployed in any given period, and management retains the flexibility to invest below Oil & Gas Portfolio Diversification: Basins Minerals and Royalties Business Profile Appalachia Gulf Coast Midcontinent Permian Rockies Williston Other Reserves owned by Minerals and Royalties 35425_NACCO_Color_ACG.indd 14 2026/3/12 : AM
15ANNUAL REPORT Bringing Natural Resources to Life Bringing Natural Resources to Life or above the target level when warranted by asset quality and expected returns. The U.S. mineral and royalty market represents a multi-billion- dollar asset class with substantial remaining growth opportunities. Catapult has evaluated numerous potential transactions and has closed on less than one percent of screened opportunities, underscoring the selective nature of its capital allocation framework. This rigorous approach emphasizes value creation over volume and supports a repeatable, low-cost acquisition model capable of scaling over time. Recent acquisitions exemplify this strategy, including a $4.6 million acquisition in July 2025 of additional mineral interests in the Permian Basin that combines producing wells with future development upside through existing operators. Catapult has also made a significant investment in a growing, private upstream production company that holds operated and non-operated working interests in oil and natural gas assets, providing additional diversification and upside potential. In 2025, Catapult invested an additional $15 million in this company. Income Generation and Long- Term Value Creation The Minerals and Royalties business generates recurring income streams through investments in a diverse pool of mineral interests. These recurring cash flows, tied to both current production and future development, are expected to span decades. Through disciplined capital allocation, broad diversification and a patient investment horizon, Catapult has established a high-quality mineral and royalty platform that is positioned to deliver increasing levels of operating profit and EBITDA over time.

16 NACCO INDUSTRIES Bringing Natural Resources to Life Our work is focused in high-growth regions where population growth, infrastructure investment and commercial development create a large addressable market with potential for further growth. Since inception, Mitigation Resources has broadened its scope from only long-termmitigation banking projects to a diversified range of natural resource restoration and reclamation services across an expanded geographic footprint. After several years of steady investment and growth, we expect the reclamation and restoration business to generate increasing profits as this part of the business grows. The timing of profits from themitigation solutions part of the business is inherently more variable as project credits only become available for sale once certain permit criteria are met. Growth Outlook Mitigation Resources of North America® provides natural resource restoration and reclamation services, as well as stream and wetland mitigation solutions, for states, municipalities and other third-parties. Established as a natural extension of our legacy mining reclamation skills and award- winning environmental management expertise, this business leverages our proven capabilities in land reclamation, ecological restoration and regulatory coordination. Competitive Advantages The stream and wetland mitigation industry is regulated by the U.S. Army Corps of Engineers, and in some instances, state agencies. Successful execution of restoration and reclamation projects requires specialized skills and technical capabilities. We have decades of expertise collaborating with federal and state regulators, which allows our experienced team to restore disturbed land and waterways to their natural state. Our expertise and experience create a strong competitive advantage in a highly regulated market characterized by significant barriers to entry. Mitigation Resources operates under two complementary business platforms: Stream and Wetland Mitigation Banking: We develop stream and wetland mitigation banks primarily in high-growth markets across the southeastern United States where rapidly expanding development creates demand for mitigation solutions. We acquire properties with degraded streams or wetlands, restore them to natural conditions through agreements with the U.S. Army Corps of Engineers and then sell mitigation credits to developers and state agencies whose permits require credits. Each mitigation bank generally has a development and harvest cycle of approximately 10 to 12 years. While cash outlays occur primarily during the early years of project development, income is generated over an extended period as credits are released over the 10-to-12-year project cycle. Restoration and Reclamation Services: We provide ecological restoration and reclamation construction services for third parties as well as our own mitigation banking projects. Shorter-term projects under this platform complement the longer-term mitigation banking platform by generating nearer-term cash flows while utilizing the same equipment, technical expertise and personnel required for mitigation bank development.

PART I Item 1. BUSINESS General NACCO Industries, Inc.® (NACCO) and its wholly owned subsidiary, NACCO Natural Resources Corporation® (NACCO Natural Resources, and with NACCO collectively, the Company, we, our or us), bring natural resources to life by delivering aggregates, minerals, reliable fuels and environmental solutions through our robust portfolio of businesses. We operate under three reportable business segments: Utility Coal Mining, Contract Mining and Minerals and Royalties. The Utility Coal Mining segment, operated by North American Coal®, manages surface coal mines that are exclusive, long-term fuel providers for power generation companies. The Contract Mining segment, operated by North American Mining®, is a leading provider of a broad range of specialized, long-term contract mining services. The Minerals and Royalties segment, which includes the Catapult Mineral Partners® (Catapult) business, acquires and promotes the development of mineral and royalty interests and other related investments. In addition to the reportable segments discussed above, we also operate other businesses that are not currently reported as separate segments. These businesses complement our existing operations and support our long-term growth strategic objectives. Mitigation Resources of North America® (Mitigation Resources) provides natural resource restoration and reclamation services that include stream and wetland mitigation solutions. ReGen Resources is pursuing opportunities to develop new power generation resources. We also have items not directly attributable to an operating segment. These items primarily include administrative costs related to public company reporting requirements, including management and board compensation, the financial results of developing businesses and Bellaire Corporation (Bellaire). Bellaire manages long-term liabilities related to former Eastern U.S. underground mining activities. During 2025, we changed the names of our reportable segments to make it easier for our stakeholders to understand the business activities within each segment. The Utility Coal Mining, Contract Mining and Minerals and Royalties segments were formerly the Coal Mining, North American Mining and Minerals Management segments, respectively. There were no changes to the composition of each segment and therefore no changes to historical segment reporting. NACCO was incorporated as a Delaware corporation in 1986 in connection with the formation of a holding company structure for a predecessor corporation organized in 1913. Business Strategy NACCO is a growing diversified natural resource company, strategically positioned to deliver stable financial returns over the long term. Our businesses operate exclusively in the U.S. and provide critical inputs for electricity generation, construction and development, and the production of industrial minerals and products. Increasing demand for electricity, on-shoring and current federal policies are creating favorable macroeconomic trends within these industries. We continue to capitalize on these tailwinds, pursuing longer-term growth opportunities. Through our proven operational expertise, disciplined capital allocation, and an entrepreneurial yet patient approach to growth, we have methodically built unique capabilities and clear competitive advantages that enable us to capture a wide range of attractive growth opportunities. Our platform is supported by multiple vectors for value creation, and we are steadfastly committed to delivering compounding returns and expanding investor value over the long term. Our business model is purposely built for durability and resilience. Our foundation rests on a stable base of long-term coal- mining contracts which, when combined with income generated by our mineral and royalty assets, provide dependable recurring cash flows. As new long-term contracts and investments are added each year in our other businesses, these multi-year agreements create a “layering” effect as their contributions compound. Each year’s new contracts and investments add to those of prior years, delivering increasingly predictable cash flows and annuity-like returns. Our competitive advantages include decades of operational expertise in complex mining operations, long-standing customer relationships with industry leaders, exclusive dealership rights for MTECK draglines in 48 U.S. states and a proven ability to structure long term contracts that align incentives and deliver value to both NACCO and our customers. We also maintain a conservative capital structure that provides flexibility to pursue opportunities while maintaining financial stability. Our Utility Coal Mining segment, anchored by our long-term mining contracts and fee-based models that provide predictable cash flows and eliminate exposure to commodity prices, provides a solid foundation of our business. We believe the increasing demand for 24/7 electricity, driven by data centers, on-shoring of manufacturing and general economic growth, combined with the current political environment, is fundamentally changing the sentiment surrounding fossil fuel-based power generation and 1
provides stability the Utility Coal Mining business. These developments are improving industry-related regulations and reinforcing coal's role as an essential part of the reliable, baseload energy mix in the United States for the foreseeable future. We remain focused on managing coal production costs and maximizing efficiencies and operating capacity at mine locations to help customers with management fee contracts be more competitive. These activities benefit both customers and our Utility Coal Mining segment, as fuel cost is a significant driver for power plant dispatch. Increased power plant dispatch results in increased demand for coal by the Utility Coal Mining segment's customers. The Contract Mining segment represents our mining growth platform. We have long-term relationships and contracts with several of the top ten U.S. aggregates producers. Our expanding pipeline of potential mining contracts and continued engagement with customers position this segment as a key pillar for future growth. Through ongoing geographic and mineral expansion, we are building a growing portfolio of long-term contracts. New contracts and contract extensions are central to the business' organic growth strategy, with each new contract expected to contribute operating profit and EBITDA through multi- year terms that can span a decade or more. The goal is to continue Contract Mining's ongoing expansion as a leading provider of contract mining services for a variety of customers. The segment’s strong momentum is evident through recent contract wins, including a multi-year dragline services contract for a U.S. Army Corps of Engineers construction project in Palm Beach County, Florida, which showcases our ability to expand into large scale infrastructure projects while highlighting the competitive advantage of our new electric drive MTECK draglines. The Minerals and Royalties segment is another solid foundation of our business. It has constructed a high-quality, diversified portfolio of oil and gas mineral and royalty interests with recurring cash flows. As an owner of mineral and royalty interests, we are entitled to a portion of the revenues received from the sale of oil, natural gas and associated natural gas liquids. The current portfolio of well-positioned assets is expected to continue to deliver solid financial results. We seek to diversify our investment and operational risk through participation in oil and gas wells with multiple operators across multiple basins. Catapult's portfolio of oil and gas mineral and royalty interests provides steady, recurring cash flows, with strategic positions in premier basins, primarily in the Permian Basin, the Haynesville Shale basin and the Appalachian basin. We also maintain equity investments in a private company that holds operated and non-operated working interests in oil and natural gas assets in the Kansas and the Oklahoma portion of the Hugoton basin. Mitigation Resources provides natural resource restoration and reclamation services that include stream and wetland mitigation solutions. Mitigation Resources is successfully leveraging its strong reputation and clear competitive strengths to expand into additional mitigation, restoration and reclamation markets. Mitigation Resources is expected to deliver increasing profitability over time from the sale of mitigation credits and as reclamation and restoration services expand. We expect the reclamation and restoration business to generate increasing profits as this part of the business grows. The timing of profits from the mitigation solutions part of the business is inherently more variable as project credits only become available for sale once certain permit criteria are met. During 2025, Mitigation Resources operated in Alabama, Florida, Georgia, Kentucky, Mississippi, Pennsylvania, Tennessee, Texas and Virginia. NACCO established ReGen Resources to address the rapidly increasing demand for power generation in the United States. Current projects in development include solar arrays, solar-gas hybrid projects, thermal generation and carbon capture primarily on reclaimed mining properties in Louisiana, Mississippi, Ohio, Pennsylvania and Texas. ReGen develops energy infrastructure projects directly as well as through joint ventures. Our investments in solar projects are dependent, in part, on federal tax incentives to preserve economic value. We believe all current solar projects have been safe harbored in order to preserve tax credit eligibility. We believe our businesses have competitive advantages that provide value to customers, and the continuing investment in our businesses can create long-term value for stockholders. We have strategically leveraged our core mining and natural resource management skills to build a robust portfolio of affiliated businesses, and opportunities for additional growth remain strong. New contracts, acquisitions of additional mineral interests, improvements in industry-related regulations, and the development of other business opportunities should be accretive to our longer-term outlook. NACCO is committed to maintaining a conservative capital structure as it continues to grow and diversify, while avoiding unnecessary risk. We believe strategic diversification will generate cash that can be re-invested at attractive returns to strengthen and grow our businesses. We also continue to maintain the highest levels of customer service and operational excellence. Business Developments During 2025, the Contract Mining segment executed a multi-year dragline services contract for a U.S. Army Corps of Engineers construction project in Palm Beach County, Florida. This project should be accretive to earnings beginning in the second quarter of 2026. 2
During 2025 and 2024, the Contract Mining segment amended and extended existing limestone contracts with multiple customers and expanded the scope of work with several other customers. See Item 2. Properties on page 38 in this Form 10-K for a list of the Contract Mining segment's locations and customers. During 2025 and 2024, the Minerals and Royalties segment invested $15.0 million and $16.6 million, respectively, in Eiger Resources, which holds operated and non-operated working interests in oil and natural gas assets in the Kansas and the Oklahoma portion of the Hugoton basin. See Note 1 to the Consolidated Financial Statements in this Form 10-K for further information on Eiger Resources. During 2025, the Minerals and Royalties segment completed $4.6 million in acquisitions of mineral interests, primarily within the Midland Basin. The acquisition includes a mix of producing wells, as well as additional upside opportunities through future development with existing operators in the area. During 2025, we terminated NACCO's Combined Defined Benefit Plan (Combined Plan) and settled all future obligations by transferring the remaining benefit obligations to a third-party insurance company. Although the plan was over funded, we recognized a $7.8 million non-cash Pension settlement charge. See Note 1 and Note 14 to the Consolidated Financial Statements in this Form 10-K for further information on the Combined Plan. Operations Utility Coal Mining Segment The Utility Coal Mining segment operates surface coal mines under exclusive, long-term contracts to supply 100% of the fuel requirements for adjacent power plants and a synfuels plant. Each mine is fully integrated with the operation of these facilities. As of December 31, 2025, the Utility Coal Mining segment's operating coal mines were: The Coteau Properties Company (Coteau), Coyote Creek Mining Company, LLC (Coyote Creek), The Falkirk Mining Company (Falkirk) and Mississippi Lignite Mining Company (MLMC). Coteau, Falkirk and Coyote Creek are in North Dakota and MLMC is in Mississippi. Each of these mines produce lignite coal. While MLMC’s coal supply contract contains a take or pay provision, all other coal supply contracts are requirements contracts. Certain coal supply contracts can be terminated early, which would result in a reduction to future earnings. The MLMC contract is the only coal supply contract in which we are responsible for all operating costs, capital requirements and final mine reclamation; therefore, MLMC is consolidated within our financial statements. MLMC sells coal to its customer at a contractually agreed-upon price which adjusts monthly, primarily based on changes in the level of established indices which reflect general U.S. inflation rates and includes adjustments for coal quality and certain reimbursable costs. Profitability at MLMC is affected by customer demand for coal, changes in the contractually determined sales price and actual costs incurred. MLMC's customer operates the Red Hills Power Plant, which supplies electricity to the Tennessee Valley Authority (TVA) under a long-term power purchase agreement. MLMC’s contract with its customer runs through April 1, 2032. Current mine area reserves are sufficient to meet contractual requirements through the 2032 contract term. TVA’s power portfolio includes coal, nuclear, hydroelectric, natural gas and renewables. The decision regarding which power plants to dispatch is determined by TVA. As a significant portion of MLMC’s costs are fixed, reduction in dispatch and/or reduced mechanical availability of the Red Hills Power Plant can materially reduce operating results at MLMC. Conversely, periods of higher dispatch can improve results. The Red Hills Power Plant operated below full capacity and experienced periods of reduced mechanical availability during 2024 and 2025. These factors increased per ton operating costs which adversely affected operating results in both 2024 and 2025. In December 2023, MLMC received notice from its customer related to a boiler issue at the Red Hills Power Plant. While this issue has been resolved, it resulted in a reduction in customer demand which had a significant impact on our results of operations during 2024. We recognized income of $13.6 million in 2024 related to business interruption insurance recoveries that partially offset losses as a result of the boiler outage. In February 2026, MLMC received notice from its customer that the Red Hills Power Plant experienced an unplanned outage, which is expected to lead to reduced demand and an anticipated operating loss for MLMC during 2026. The Sabine Mining Company (Sabine) operates the Sabine Mine in Texas. All production from Sabine was delivered to Southwestern Electric Power Company's (SWEPCO) Henry W. Pirkey Plant (the Pirkey Plant). SWEPCO is an American Electric Power (AEP) company. As a result of the early retirement of the Pirkey Plant, Sabine ceased deliveries and commenced final reclamation on April 1, 2023. Funding for mine reclamation is the responsibility of SWEPCO, and Sabine receives compensation for providing mine reclamation services. Sabine will provide mine reclamation services through September 30, 3
2026. As of October 1, 2026, SWEPCO is obligated to acquire all of the capital stock of Sabine and complete the remaining mine reclamation. At Coteau, Coyote Creek and Falkirk, we are paid a management fee per ton of coal or heating unit (MMBtu) delivered. Each contract specifies the indices and mechanics by which fees change over time, generally in line with broad measures of U.S. inflation. Our customers are responsible for funding all mine operating costs, including final mine reclamation, and directly or indirectly providing all of the capital required to build and operate the mine. This contract structure eliminates exposure to spot coal market price fluctuations while providing predictable income and cash flow with minimal capital investment. Other than at Coyote Creek, debt financing provided by or supported by the customers is without recourse to us. See Note 16 to the Consolidated Financial Statements in this Form 10-K for further discussion of Coyote Creek's guarantees. Coteau, Coyote Creek, Falkirk and Sabine each meet the definition of a variable interest entity (VIE). In each case, NACCO is not the primary beneficiary of the VIE as it does not exercise financial control; therefore, we do not consolidate the results of these operations within our financial statements. Instead, these contracts are accounted for as equity method investments. We regularly evaluate if there are reconsideration events which could change our conclusion as to whether these entities meet the definition of a VIE and the determination of the primary beneficiary. The income before income taxes associated with these VIEs is reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations and our investment is reported on the line Investments in unconsolidated subsidiaries in the Consolidated Balance Sheets. The mines that meet the definition of a VIE are referred to collectively as the Unconsolidated Subsidiaries. For tax purposes, the Unconsolidated Subsidiaries are included within our consolidated U.S. tax return; therefore, the Income tax (benefit) provision line on the Consolidated Statements of Operations includes income taxes related to these entities. See Note 16 to the Consolidated Financial Statements in this Form 10-K for further information on the Unconsolidated Subsidiaries. We perform contemporaneous reclamation activities at each mine in the normal course of operations. Under all of the Unconsolidated Subsidiaries’ contracts, our customer has the obligation to fund final mine reclamation activities. Under certain contracts, the Unconsolidated Subsidiary holds the mine permit and is therefore responsible for final mine reclamation activities. To the extent the Unconsolidated Subsidiary performs such final reclamation, it is compensated for providing those services in addition to receiving reimbursement from customers for costs incurred. See Item 2. Properties on page 25 in this Form 10-K for discussion of the Utility Coal Mining segment's mineral resources and mineral reserves. Contract Mining Segment The Contract Mining segment provides value-added contract mining and other services for producers of industrial minerals and products. The segment is a platform for our growth and diversification of mining activities outside of the thermal coal industry. Contract Mining provides contract mining services for independently owned mines and quarries, creating value for our customers by performing the mining aspects of our customers’ operations. This allows customers to focus on their areas of expertise: materials handling and processing, product sales and distribution. As of December 31, 2025, the Contract Mining segment operates at quarries in Florida, Arkansas and Nebraska and is expected to begin operations at a quarry in Arizona during the first half of 2026. Beginning in 2026, the Contract Mining segment will also provide dragline services as part of a U.S. Army Corps of Engineers construction project in Palm Beach County, Florida. In addition, Contract Mining's subsidiary, Sawtooth Mining (Sawtooth), is the exclusive provider of comprehensive mining services for the Thacker Pass lithium project in Humboldt County, Nevada. Thacker Pass is owned by a joint venture between Lithium Americas Corp. (TSX:LAC) (NYSE: LAC) and General Motors Holdings LLC. The U.S. Department of Energy holds warrants to purchase five percent non-voting, non-transferable equity in this joint venture. Thacker Pass is targeting initial lithium production in late 2027. The contract requires reimbursement for costs of mining, capital expenditures and mine closure. Sawtooth will recognize a contractually agreed upon production fee once the mine is operating. In addition to providing comprehensive mining services, Sawtooth is currently assisting with certain construction services and will transport clay tailings once lithium production commences. See Item 2. Properties on page 38 in this Form 10-K for a list of the Contract Mining segment's locations and customers. Minerals and Royalties Segment The Minerals and Royalties segment derives income primarily by leasing our royalty and mineral interests to third-party exploration and production companies, and, to a lesser extent, other mining companies, granting them the rights to explore, develop, mine, produce, market and sell gas, oil, and coal in exchange for royalty payments based on the lessees' sales of those minerals. 4
The Minerals and Royalties segment owns royalty interests, mineral interests, non-participating royalty interests and overriding royalty interests (collectively mineral and royalty interests). • Royalty Interest. Royalty interests generally result when the owner of a mineral interest leases the underlying minerals to an exploration and production company pursuant to an oil and gas lease. Typically, the resulting royalty interest is a cost-free percentage of production revenues for minerals extracted from the acreage. A holder of royalty interests is generally not responsible for capital expenditures or lease operating expenses, but royalty interests may be calculated net of post-production expenses. Royalty interests leased to producers expire upon the expiration of the oil and gas lease and revert to the mineral owner. • Mineral Interest. Mineral interests are perpetual rights of the owner to explore, develop, exploit, mine and/or produce any or all of the minerals lying below the surface of the property. The holder of a mineral interest has the right to lease the minerals to an exploration and production company. Upon the execution of an oil and gas lease, the lessee (the exploration and production company) becomes the working interest owner and the lessor (the mineral interest owner) has a royalty interest. • Non-Participating Royalty Interest (NPRIs). NPRI is an interest in oil and gas production which is created from the mineral estate. The NPRI is expense-free, bearing no operational costs of production. The term non-participating indicates that the interest owner does not share in the bonus, rentals from a lease, nor the right to participate in the execution of oil and gas leases. The NPRI owner does; however, typically receive royalty payments. • Overriding Royalty Interest (ORRIs). ORRIs are created by carving out the right to receive royalties from a working interest. Like royalty interests, ORRIs do not confer an obligation to make capital expenditures or pay for lease operating expenses and have limited environmental liability; however, ORRIs may be calculated net of post- production expenses, depending on how the ORRI is structured. ORRIs that are carved out of working interests are linked to the same underlying oil and gas lease that created the working interest, and therefore, such ORRIs are typically subject to expiration upon the expiration or termination of the oil and gas lease. We may own more than one type of mineral and royalty interest in the same tract of land. For example, where we own an ORRI in a lease on the same tract of land in which we own a mineral interest, the ORRI in that tract will relate to the same gross acres as the mineral interest in that tract. During 2025 and 2024, the Minerals and Royalties segment invested $15.0 million and $16.6 million, respectively, in Eiger Resources, which holds operated and non-operated working interests in oil and natural gas assets in the Kansas and the Oklahoma portion of the Hugoton basin. Eiger Resources meets the definition of a VIE. NACCO is not the primary beneficiary of the VIE as it does not exercise financial control; therefore, we do not consolidate the results of these operations within our financial statements. Instead, this investment is accounted for under the equity method. Our investment is reported on the line Equity method investment in Eiger Resources in the Consolidated Balance Sheets. Due to the timing and availability of financial information, earnings or losses from this investment are recorded on a one quarter lag. See Note 1 to the Consolidated Financial Statements in this Form 10-K for further information on Eiger Resources. Excluding the Eiger Resources investment described above, total consideration for the acquisitions of mineral and royalty interests was $4.6 million and $0.7 million, in 2025 and 2024, respectively. The 2025 acquisitions included 10.5 thousand gross acres and 0.4 thousand net royalty acres. The 2024 acquisitions include 13.7 thousand gross acres and 0.6 thousand net royalty acres. The Minerals and Royalties segment also manages legacy royalty and mineral interests located in Ohio (Utica and Marcellus shale natural gas), Louisiana (Haynesville shale and Cotton Valley formation natural gas), Texas (Cotton Valley and Austin Chalk formation natural gas), Mississippi (coal), Pennsylvania (coal, coalbed methane and Marcellus shale natural gas), Alabama (coal, coalbed methane and natural gas) and North Dakota (coal, oil and natural gas). The majority of our legacy reserves were acquired as part of our historical coal mining operations. Total oil and gas mineral and royalty interests include approximately 208.0 thousand gross acres and 64.4 thousand net royalty acres at December 31, 2025. Net royalty acres are calculated based on our ownership and royalty rate, normalized to a standard 1/8th royalty lease, and assumes a 1/4th royalty rate for unleased acres. See Item 2. Properties on page 40 in this Form 10-K for discussion of the Mineral and Royalties segment's proved reserves. 5
Customers The principal customers of the Utility Coal Mining segment are electric utilities and an independent power provider. The principal customers of the Contract Mining segment are limestone producers and to a lesser extent, construction firms and sand and gravel producers. In addition, the Contract Mining segment will serve as exclusive contract miner for the Thacker Pass lithium project in northern Nevada. The Minerals and Royalties segment generates income primarily from royalty-based lease payments from oil, gas and to a lesser extent, coal producers. The pricing of oil, gas and coal sales is primarily determined by supply and demand in the marketplace and can fluctuate considerably. As a mineral owner, we have limited access to timely information, involvement, and operational control over the volumes of oil, gas and coal produced and sold and the terms and conditions, including price, on which such volumes are marketed and sold. In both 2025 and 2024, three customers accounted for 10% or more of consolidated revenue. The following represents the revenue attributable to each of these entities as a percentage of consolidated revenue for those years: Percentage of Consolidated Revenues Segment 2025 2024 Utility Coal Mining customer 31 % 29 % Contract Mining customer 25 % 24 % Contract Mining customer 10 % 11 % The loss of any of these customers could have a material adverse effect on the results of operations attributable to the applicable segment and on our consolidated results of operations. Based on industry information, we believe we were one of the ten largest coal producers in the U.S. in 2025 and 2024. Based on industry information, we believe that we were the largest dragline operator in the U.S. in 2025 and 2024. Competition Coteau, Coyote Creek, Falkirk and MLMC each have only one customer. Our coal mines are directly adjacent to our customer’s property, with economical delivery methods that include conveyor belt delivery systems linked to the customer’s facilities or short-haul rail systems. All of the mines in the Utility Coal Mining segment are the most economical suppliers to each of their respective customers as a result of transportation advantages over competitors. In addition, the customers' facilities were specifically designed to use the coal. The coal industry competes with other sources of energy, particularly oil, gas, hydro-electric power and nuclear power, and, to a lesser extent, wind and solar. Natural gas-fired power plants have the most potential to displace coal-fired electric baseload power generation in the near term. Fluctuations in natural gas prices and the availability of renewable energy sources can contribute to changes in power plant dispatch and customer demand for coal. Among the factors that affect competition are the price and availability of oil and natural gas, our customers' dispatch decisions, the time and expenditures required to develop energy sources, the cost of transportation, the cost of compliance with governmental regulations and the impact of federal and state energy policies. The ability of the Utility Coal Mining segment to maintain comparable levels of coal production at existing facilities and develop our reserves will depend upon the interaction of these factors. The Contract Mining segment faces competition from producers of aggregates, lithium or other minerals that choose to self- perform mining operations and from other mining companies. In the Minerals and Royalties segment, the oil and gas industry is intensely competitive; we primarily compete with companies and investors for the acquisition of oil and gas properties, some of which have greater resources and may be able to pay more for productive oil and natural gas properties or to define, evaluate, bid for and purchase a greater number of properties than our financial resources permit. Additionally, many of the Minerals and Royalties segment's competitors are, or are affiliated with, operators that engage in the exploration and production of their oil and gas properties, which allows them to acquire larger assets that include operated properties. Larger or more integrated competitors may be able to absorb the burden of existing, and any changes to, federal, state and local laws and regulations more easily than we can, which would adversely affect our competitive position. The integrated competitors may also have a better understanding of when minerals they acquire will be developed, as they are often the developer. The Minerals and Royalties segment’s ability to acquire additional properties in the future will be dependent upon our ability to evaluate and select suitable properties and to consummate transactions in a highly 6
competitive environment. Further, oil and natural gas compete with other forms of energy available to customers, primarily based on price. Changes in the availability or price of oil and natural gas or other forms of energy, as well as business conditions, conservation, legislation, regulations, and the ability to convert to alternate fuels and other forms of energy may affect the demand for oil and natural gas. At Mitigation Resources, there are significant barriers to entry and the market is highly regulated; however, the markets we serve are highly fragmented and we compete with a number of regional companies. Some of these companies may have greater financial and other resources, while others may be smaller and more specialized and may concentrate their resources on specific areas of expertise. Our results are also affected by the number of competitors in a market, the demand for services in a particular market, the pricing practices of competitors and the entry of new competitors in a market. Seasonality We have experienced limited variability in our results due to the effect of seasonality; however, variations in coal demand can occur as a result of the timing and duration of planned or unplanned outages at our customers' facilities. Variations in coal demand can also occur as a result of changes in market prices of competing fuels such as natural gas, wind and solar power and demand for electricity, which can fluctuate based on changes in weather patterns. In addition, demand for coal-fired power generation can increase due to unusually hot or cold weather as consumers use more air conditioning or heating, respectively. Conversely, mild weather can result in weaker demand for coal-fired power generation. The Contract Mining segment extracts a significant amount of the annual limestone produced in Florida. The Florida construction industry can be affected by the cyclicality of the economy, seasonal weather conditions and significant weather events, all of which can result in variations in demand for aggregates. In the Minerals and Royalties segment, oil and natural gas wells have high initial production rates and follow a natural decline before settling into relatively stable, long-term production. Decline rates can vary due to factors like well depth, well length, geology, formation pressure and facility design. In addition to the natural production decline curve, royalty income can fluctuate favorably or unfavorably in response to a number of factors outside of our control, including the number of wells being operated by third parties, fluctuations in commodity prices (primarily oil and natural gas), fluctuations in production rates associated with operator decisions, regulatory risks, our lessees' willingness and ability to incur well-development and other operating costs and changes in the availability and continuing development of infrastructure. Weather conditions affect the demand for, and prices of, natural gas and can also delay drilling activities. Demand for natural gas is typically higher during the winter, resulting in higher natural gas prices during the first and fourth quarters. Seasonal weather conditions can limit drilling and producing activities and other oil and natural gas operations. Due to these seasonal fluctuations, the Minerals and Royalties segment's results of operations for individual quarterly periods may not be indicative of the results that may be realized on an annual basis. Human Capital As of December 31, 2025, we had approximately 1,700 employees, including approximately 1,100 employees at our unconsolidated mining operations. None of our employees are represented by a collective bargaining agreement. NACCO believes we have good relations with our employees. Market-Based Compensation: We believe our employees are critical to our success and we invest in our employees by offering a market-based competitive total rewards package that includes a combination of salaries and wages and a benefits package that promotes employee well-being across all aspects of their lives. We offer a 100% 401(k) matching contribution up to 5% of compensation, which is immediately vested. We automatically enroll new employees in our 401(k) plan at a 5% deferral rate, and in 2024, we implemented a program to re-enroll current employees who were not deferring at least 5%. Additionally, NACCO offers a generous profit-sharing contribution for all of our full-time and part-time employees. We provide employee wages that are competitive and consistent with employee positions, skill levels, experience, knowledge and geographic location. Benefits offered to employees include: • Medical, dental and vision benefits for employees, spouses and dependents; • Flexible spending accounts for both healthcare and dependent care; • Health savings accounts and health reimbursement accounts, certain of which receive company contributions; • Paid vacation and holidays; • Parental leave; • Short-term and long-term disability benefits; • Wellness incentives and programs for employees; 7
• Life and AD&D insurance benefits; • Identity protection benefits; • Charitable donation matches; and • Employee assistance program. Employee Development: We know that our people are our greatest asset and we recognize that our culture and success is strengthened when employees are respected, motivated and engaged. We work to match employees with assignments that capitalize on the skills, talents and potential of each employee, and we provide opportunities for professional growth. NACCO believes training is a critical component of employee well-being and growth. Training ranges from equipment-specific task training and enhanced safety procedures to strategic leadership and management training, ethics training and role-specific training. Employees are encouraged to pursue continued professional development, skills training and other educational opportunities. Qualified employees are eligible to participate in a tuition reimbursement program to advance their formal education. Internships are also available across our family of companies. We believe in hiring, engaging, developing and promoting people who are fully able to meet the demands of each position, regardless of race, color, religion, gender, sexual orientation, gender identity, national origin, age, veteran status or disability. Safety: Employee safety in the workplace is one of our core values. We are committed to strict compliance with applicable laws and regulations regarding workplace safety and provide on-going safety training, education and communication. Safety performance is monitored through physical observations from both internal and external parties and through the reporting of key metrics. Our mining operations are regulated by the U.S. Mine Safety and Health Administration and non-mining operations are regulated by the U.S. Occupational Safety and Health Administration. During 2025, an incident at a quarry in Florida resulted in two employee fatalities. The event is currently under investigation by the U.S. Mine Safety and Health Administration. In the aftermath of this incident, we are reviewing ways to further strengthen our safety guidelines and reinforce our safety expectations across the organization. Our employees are the nucleus of NACCO’s success, and their safety will always come before all else. We maintain insurance with respect to operating the dragline involved in this incident and related liabilities (which are subject to deductibles) and believe that our insurance coverage will be adequate to cover any liabilities. Our operations have safety personnel who train employees in safe work practices, review safety-related incidents and recommend improvements when appropriate. Hazards in the workplace are actively identified and management tracks incidents so remedial actions can be taken to improve workplace safety. As part of our efforts to continuously improve our safety programs, NACCO’s safety professionals from across the organization meet regularly to share ideas and best practices. We believe communication related to safety incidents, near misses and protocols is essential to continuously developing and maintaining robust safety practices. This communication also enables the identification and correction of operational practices that might impair employee safety or health. Every employee is responsible and accountable for safety performance. Company Ethics: We have processes in place for compliance with our Code of Corporate Conduct, Insider Trading Policy and Anti-Corruption Policy. All of our Directors and employees annually complete certifications to comply with our Code of Corporate Conduct. In addition, all of our employees are required to complete annual Code of Corporate Conduct training. The Code of Corporate Conduct, Insider Trading Policy and Anti-Corruption Policy require employees to comply with applicable laws and regulations, maintain high ethical standards and report situations of actual or potential noncompliance. The Company believes the code and these policies represent sound practices and provide a strong framework for the conduct of our Board and employees. All NACCO personnel are required to report without delay any conduct which they believe to be illegal or a violation of our policies. The identity of any NACCO personnel making such a report is kept in strict confidence except as required by law, and we utilize a third-party hotline to ensure reports can be generated anonymously. Retaliation in any form against an individual who exercises their right to make a complaint in good faith is strictly prohibited. Community Engagement: We value our local communities and provide support through volunteer activities, financial contributions and well-paying jobs. NACCO believes in making long-term investments in the areas where we operate by supporting numerous charitable efforts, including educational, arts and community organizations. Community engagement is encouraged and supported through our matching gift program. We will match employee contributions up to $5,000 per employee if program criteria are met. 8
Available Information We make our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments to those reports available through our website, www.nacco.com, as soon as reasonably practicable after such material is electronically filed with, or furnished to, the Securities and Exchange Commission (SEC). The content of our website is not incorporated by reference into this Form 10-K or in any other report or document filed with the SEC, and any reference to our website is intended to be an inactive textual reference only. The SEC maintains an internet site at http://www.sec.gov that contains reports, proxy and information statements, and other information regarding us and other issuers that file electronically with the SEC. Under Rule 12b-2 of the Exchange Act, we qualify as a smaller reporting company because our public float as of the last business day of our most recently completed second quarter was less than $250 million. For as long as we remain a smaller reporting company, we may take advantage of certain exemptions from the SEC’s reporting requirements that are otherwise applicable to public companies that are not smaller reporting companies. Government Regulation and Environmental Matters Operations on our properties, projects and mineral interests must be conducted in compliance with all applicable federal, state and local laws and regulations. These laws and regulations include matters involving the discharge of materials into the environment, employee health and safety, permits and other licensing requirements, reclamation and restoration of properties, management of materials, air quality, water quality, limitations on land use as well as the protection of wetlands, plant and wildlife. These laws and regulations, which are extensive and subject to change, could have a significant effect on our production costs and our competitive position. While it is not possible to quantify the costs of compliance with all applicable federal, state and local laws and regulations, those costs could be significant. Future legislation, regulations or orders, as well as future interpretations and more rigorous enforcement of existing laws, regulations or orders, may result in substantial increases in equipment and operating costs and delays, interruptions, or a termination of operations, the likelihood or extent of which we cannot predict. We intend to continue to comply with regulatory requirements as they evolve by timely implementing necessary modifications and/or operating procedures. The following is a summary of the more significant existing government regulations and environmental matters to which we or our customers'/lessees' business operations are subject and for which compliance may have a material adverse effect on our business, results of operations and financial condition. For additional information regarding our material risks, please refer to Item 1A - Risk Factors on page 15. Mine Health and Safety Laws The Federal Mine Safety and Health Act of 1977 imposes safety and health standards on all mining operations. Regulations are comprehensive and affect numerous aspects of mining operations, including training of mine personnel, mining procedures, blasting, the equipment used in mining operations and other matters. The Federal Mine Safety and Health Administration enforces compliance with these federal laws and regulations. Environmental Laws Our operations are subject to various federal environmental laws, as amended, including: • the Surface Mining Control and Reclamation Act of 1977 (SMCRA); • the Clean Air Act, including amendments to that act in 1990 (CAA); • the Clean Water Act of 1972 (CWA); • the Resource Conservation and Recovery Act (RCRA); • the National Environmental Policy Act of 1970 (NEPA); and • the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). In addition to these federal environmental laws, various states have enacted environmental laws that provide for higher levels of environmental compliance than similar federal laws. These state environmental laws require reporting, permitting and/or approval of many aspects of operations. We have ongoing training, compliance and permitting programs to ensure compliance with such environmental laws. Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent and costly pollution control or waste handling, storage, transport, disposal or cleanup requirements could materially adversely affect our business. Surface Mining Control and Reclamation Act (SMCRA) SMCRA establishes mining, environmental protection and reclamation standards for all aspects of surface coal mining operations. SMCRA stipulates compliance with many other major environmental programs. Where state regulatory agencies have adopted federal mining programs under SMCRA, the state becomes the primary regulatory authority. 9
Coal mine operators must obtain SMCRA permits and permit renewals for coal mining operations from the applicable regulatory agency. These SMCRA permit provisions include requirements for coal prospecting, mine plan development, topsoil removal, storage and replacement, selective handling of overburden materials, mine pit backfilling and grading, protection of the hydrologic balance, surface drainage control, mine drainage, mine discharge control and treatment and revegetation. Although mining permits have stated expiration dates, SMCRA provides for a right of successive renewal. The cost of obtaining surface mining permits can vary widely depending on the quantity and type of information that must be provided to obtain the permits. SMCRA establishes operational, reclamation and closure standards for surface coal mines. We accrue for the costs of final mine closure, including the cost of treating mine water discharges, at mines where our businesses hold the mining permit. While these obligations are largely unfunded, they can require securitization through bonding, with the exception of the final mine closure costs for the Coyote Creek Mine, which are being funded by the customers throughout the production stage. Clean Air Act (CAA) and Air Emissions The process of burning coal and drilling for oil and natural gas can cause many compounds and impurities to be released into the air, including sulfur dioxide, nitrogen oxides, methane, mercury, particulates and other matter. Federal and state laws that extensively regulate the emissions of materials into the air affect our operations both directly and indirectly. Direct impacts on operations can occur through permitting requirements and/or emission control requirements relating to air contaminants, especially particulate matter. Indirect impacts on operations can occur through regulation of the air emissions of sulfur dioxide, nitrogen oxides, methane, mercury, particulate matter and other compounds. Greenhouse Gas (GHG) Emissions and the Mercury and Air Toxics Standards (MATS) In May 2024, the Environmental Protection Agency (EPA) published the final rules for GHG emissions and MATS in the Federal Register. The GHG standards are based on technologies such as carbon capture and sequestration/storage and natural gas co-firing. The compliance deadline for existing coal-fired, steam generating electric generating units (EGUs) planning to install carbon capture and sequestration/storage technology has been extended to January 1, 2032 for plants that intend to operate beyond 2039. If a coal-fired plant intends to close prior to 2032, no controls will be required and if a plant plans to close between 2032 and 2039, they must begin co-firing with natural gas by January 1, 2030. The MATS rules finalize changes for the filterable particulate matter surrogate emission standard for non-mercury metal hazardous air pollutants for existing coal- fired EGUs, the filterable particulate matter emission standard compliance demonstration requirements and the mercury emission standard for lignite-fired EGUs. In 2023, the EPA issued its methane rules that establish new source and first-time existing source standards of performance for GHG and volatile organic compound emissions for crude oil and natural gas well sites, natural gas gathering and boosting compressor stations, natural gas processing plants, and transmission and storage facilities. The EPA also finalized a Waste Emissions Charge implementation rule in November 2024; however, the Congressional Review Act was used to disapprove EPA’s implementation rule in March 2025. As a result, no methane emission fees are being assessed or collected. In November 2025, the EPA announced a final rule to extend several compliance deadlines for the oil and gas industry. The EPA under the Trump Administration has made efforts to repeal or otherwise modify GHG and MATS regulations at the federal level. On June 11, 2025, EPA announced a plan to repeal the GHG rule but has not yet published a final repeal of the rule. On February 12, 2026, the EPA revoked the 2009 Endangerment Finding, which found that six GHGs endanger public health, thus removing the EPA’s authority to regulate GHGs. Additionally, on February 23, 2026, the EPA repealed the MATS rule. If not repealed, the 2024 GHG rule will require compliance at our customers' facilities as early as 2029 and 2032. We cannot predict whether such efforts will ultimately be successful or what effects they may have on our business or results of operations and on the business and results of operations of our customers/lessees. At the same time, many states, regions, and governmental bodies have adopted or are considering policies that regulate greenhouse gas emissions, including imposing fees or taxes on emissions from certain facilities such as coal-fired power plants through cap-and-trade programs, carbon taxes, or climate “superfund” laws. Other states are advancing plans to expand renewable energy use, which may further reduce the role of coal and other fossil fuels. Depending on future federal or state regulatory actions and the outcomes of potential legal challenges, demand for coal, oil, and natural gas could decline, adversely affecting our operations. 10
National Ambient Air Quality Standards (NAAQS) The CAA requires the EPA to set NAAQS for certain air pollutants. The EPA has set NAAQS for ozone, particulate matter, sulfur dioxide, nitrogen oxides, carbon monoxide and lead. Over the years, the EPA has made the NAAQS more stringent. Each state must develop a plan to be approved by the EPA for achieving and maintaining NAAQS within its borders. These plans impose limits on emissions from pollution sources, including fossil fuel-fired plants. Areas meeting NAAQS are designated as attainment areas. Areas not meeting NAAQS are designated as non-attainment areas, and more stringent requirements apply in those areas, including stricter controls on industrial facilities and more complicated and public permitting processes. During 2024, the EPA finalized more stringent NAAQS for particulate matter that may increase the likelihood of certain areas being designated as non-attainment areas. The more stringent NAAQS are currently subject to a legal challenge seeking to overturn the standards, but the challenge is currently being held in abeyance. On March 12, 2025, the EPA announced that it would be reconsidering the NAAQS for particulate matter and that it would release guidance to increase flexibility on NAAQS implementation and direction on permitting obligations. We are currently unable to predict any specific changes or how such changes, if any, may impact our operations. Cross-State Air Pollution Rule (CSAPR) In 2011, the EPA finalized the CSAPR to address interstate transport of pollutants. While the CSAPR affects states in the eastern half of the U.S. and Texas, it does not affect EGUs in North Dakota. This rule imposes additional emission restrictions on coal-fired power plants to attain ozone and fine particulate NAAQS. In 2023, the EPA published the Good Neighbor Plan, which decreases, over time, the ozone-season NOx allowances for EGUs in the affected states by assuming that participants in this cap-and-trade program had or would optimize existing NOx controls and later install additional NOx controls. In 2024, the U.S. Supreme Court (SCOTUS) decided to stay the Good Neighbor Plan pending further review. In March 2025, the EPA announced a rollback of the Good Neighbor Plan, leaving in place pre-Good Neighbor Plan requirements from CSAPR. Additional emission restrictions under the CSAPR or the Good Neighbor plan would increase the cost of operating the customer facility serviced by MLMC. Regional Haze The EPA promulgated a regional haze program designed to protect and to improve visibility at and around Class I Areas, which are generally National Parks, National Wilderness Areas and International Parks. State implementation of the EPA’s Regional Haze Rule could require our North Dakota customers to incur significant new costs at their respective power plants, which could result in the premature closure of such power plants and their associated mines. The North Dakota Department of Environmental Quality (NDDEQ) finalized its state implementation plan and submitted it to the EPA for approval in August 2022. The NDDEQ determined that visibility progress was being made and did not require significant emissions controls at the North Dakota power plants. In 2024, the EPA issued a proposed partial denial of the North Dakota state implementation plan. In May 2025, the EPA granted an administrative petition for the EPA to reconsider a portion of the Clean Air Act’s regional haze rule which disapproved North Dakota's state implementation plan. On a broader scale, in March 2025, the EPA announced it was reconsidering its implementation of the Regional Haze Program and intends to review and revise the regulations to streamline the program and change compliance expectations. We are currently unable to predict any specific changes or how such changes, if any, may impact our operations. Clean Water Act (CWA) The CWA affects certain of our operations by establishing in-stream water quality standards and treatment standards for wastewater discharge, including from coal mines. In many instances, mining operations require securing CWA authorization or a permit from the U.S. Army Corps of Engineers (USACE) for operations in waters of the United States (WOTUS.) In 2023, the SCOTUS issued a decision in the case of Sackett v. Environmental Protection Agency, addressing the definition of WOTUS with regards to the CWA. The decision provides a clear standard that substantially restricts the USACE and the EPA’s ability to regulate certain types of wetlands and streams. Specifically, wetlands that do not have a continuous surface connection with traditional interstate navigable water are not federally jurisdictional. As a result of the Sackett decision, the EPA and the USACE revised the definition of WOTUS and promulgated a final rule. The new rule did not go into effect in states where a stay had been issued for the previous rule, including North Dakota, Texas, Louisiana, and Mississippi. In these states, the legal challenges to this rule have resumed. In November 2025, the EPA and the USACE proposed a new definition of WOTUS that contemplates a substantially narrower jurisdiction. We are currently unable to predict any specific changes or how such changes, if any, may impact our operations. Bellaire is treating mine water drainage from coal refuse piles associated with former underground coal mines in Ohio and Pennsylvania and is treating mine water from a former underground coal mine in Pennsylvania. Bellaire anticipates that it will need to continue these activities indefinitely. In 2004, Bellaire was notified by the Pennsylvania Department of Environmental 11
Protection that it was required to establish a mine water treatment trust to serve as a long-term funding mechanism related to this obligation. See Note 7 and Note 9 to the Consolidated Financial Statements in this Form 10-K for further information on Bellaire. Resource Conservation and Recovery Act (RCRA) The RCRA affects coal mining operations by establishing requirements for the treatment, storage and disposal of wastes, including hazardous wastes. Coal mine wastes, such as overburden and coal cleaning wastes, currently are exempted from hazardous waste management. In 2020, the EPA finalized changes to the coal combustion residual (CCR) rule that classified all clay-lined surface impoundments that receive CCR as unlined. The EPA also established alternative deadlines to cease receipt of waste to include new site-specific alternatives due to lack of disposal capacity with a deadline to initiate closure and a new site-specific alternative due to permanent cessation of coal-fired boilers with deadlines to complete closure. In May 2023, the EPA published proposed regulations that would impose federal regulatory requirements for previously exempt inactive CCR surface impoundments at inactive facilities (legacy CCR surface impoundments) and CCR Management Units (CCRMUs). In May 2024, the EPA published a final rule amending CCR regulations which introduced new requirements for the management of coal ash at active coal-fired power plants and inactive coal-fired power plants with a legacy surface impoundment. The regulations impose new requirements including groundwater monitoring, closure standards, post-closure care obligations, and potential remediation activities. During 2025, the EPA announced a number of interpretation and guidance changes to its CCR Rule, including its intention to reconsider the CCR Rule, which will require a new round of notice-and- comment rulemaking. No schedule for this rulemaking has yet been announced. We are currently unable to predict any specific changes or how such changes, if any, may impact our operations. In compliance with these regulations, Falkirk's customer, the owner of the Coal Creek Station power plant, submitted a CCR Part B application to the EPA in 2020 asserting a unit complied with the CCR rules. In 2023, the EPA proposed to deny the owner’s application. The owner and other parties submitted additional information and comments supporting the owner’s position. The owner and the EPA continue to work through a path forward to provide a long-term solution. Additionally, the owner is taking operational steps to ensure there is no interruption to its disposal needs and no interruption of operations while working through the issue. National Environmental Policy Act (NEPA) The NEPA requires federal agencies to review the environmental impacts of their decisions and issue either an environmental assessment or an environmental impact statement. There are certain actions associated with surface coal mining that may trigger these types of assessments by federal agencies. Historically, this process may take several years to complete. In May 2025, the SCOTUS significantly narrowed the scope of environmental review required under NEPA, reinforcing that courts must give substantial deference to federal agencies. The SCOTUS iterated that NEPA is a procedural statute, not outcome-mandating. Furthermore, agencies are not required to analyze effects from separate, future or geographically distinct projects. Finally, agencies are permitted to limit NEPA analysis to impacts directly tied to the project and within their jurisdiction. The Council on Environmental Quality (CEQ) emphasized the need for agencies to streamline procedures and ensure that the NEPA process does not go on for too long in time or in volume. In January 2026, the CEQ published a final rule formally rescinding all NEPA implementation regulations and providing that CEQ will no longer issue government-wide NEPA regulations. This action moves all NEPA implementation to each individual federal agency and each individual federal agency must now revise its own NEPA procedures within one year, per CEQ direction. We are currently unable to predict any specific changes or how such changes, if any, may impact our operations. Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) CERCLA and similar state laws create liabilities for the investigation and remediation of releases of hazardous substances into the environment and for damages to natural resources. We must also comply with reporting requirements under the Emergency Planning and Community Right-to-Know Act and the Toxic Substances Control Act. Endangered Species Act (ESA) The ESA and analogous state laws restrict activities that may affect endangered or threatened species or their habitats. Some of our properties, projects or mineral interests may be located in areas that are or may be designated as habitats for endangered or threatened species, and previously unprotected species may later be designated as threatened or endangered in areas where we own property, projects or mineral interests. The ESA restricts activities that may affect federally identified endangered and threatened species or their habitats through the implementation of operating limitations or restrictions or a temporary, seasonal or permanent ban on operations in affected areas. Similar protections are afforded to migratory birds under the Migratory Bird Treaty Act (MBTA). Compliance with ESA and MBTA requirements can significantly delay, limit, or even prevent the development of our properties, projects and mineral interests, and also result in increased costs. 12
Drilling and Production Our third-party lessees and our equity method investee are subject to various types of regulation at the federal, state and local level. These types of regulation include requiring permits for the drilling of wells, drilling bonds and generating reports concerning operations. The states, and some counties and municipalities, in which we have mineral interests also regulate one or more of the following: • the location of wells; • the method of drilling and casing wells; • the timing of construction or drilling activities, including seasonal wildlife closures; • the rates of production; • the surface use and restoration of properties upon which wells are drilled; • the plugging and abandoning of wells; and • notice to, and consultation with, surface owners and other third parties. State laws regulate the size and shape of drilling and spacing units or proration units governing the pooling of oil and natural gas properties. Some states allow forced pooling or integration of tracts to facilitate exploration while other states rely on voluntary pooling of lands and leases. In some instances, forced pooling or unitization may be implemented by third parties and may reduce our interest in the unitized properties. In addition, state conservation laws establish maximum rates of production from oil and natural gas wells, generally prohibit the venting or flaring of natural gas and impose requirements regarding the ratability of production. These laws and regulations may limit the amount of oil and natural gas that the lessees of our mineral interests can produce from existing wells or limit the number of wells or the locations at which operators can drill. Moreover, each state generally imposes a production or severance tax with respect to the production and sale of oil, natural gas and NGLs within its jurisdiction. Federal, state and local regulations provide detailed requirements for the abandonment of wells, closure or decommissioning of production facilities and pipelines and for site restoration in areas where the operators of the acreage underlying our mineral and royalty interests operate. The USACE and many other state and local authorities also have regulations for plugging and abandonment, decommissioning and site restoration. Although the USACE does not require bonds or other financial assurances, some state agencies and municipalities do have such requirements. Regulation of Hydraulic Fracturing The operators that produce oil and gas sometimes engage in hydraulic fracturing to stimulate production of hydrocarbons from tight formations, including shales. The process involves the injection of water, sand and chemicals under pressure into formations to fracture the surrounding rock and stimulate production. The process is typically regulated by state oil and natural gas commissions. Several states where we own interests in oil and gas producing properties, including Texas, have adopted regulations that could restrict or prohibit hydraulic fracturing in certain circumstances with regard to the use of fracturing fluids or require the disclosure of the composition of hydraulic-fracturing fluids. For example, the Texas Legislature previously adopted legislation requiring oil and gas operators to publicly disclose the chemicals used in the hydraulic fracturing process. The Texas Railroad Commission subsequently adopted rules and regulations implementing this legislation that apply to all wells for which the Railroad Commission issues an initial drilling permit. This law requires that the well operator disclose the list of chemical ingredients subject to the requirements of the Occupational Safety and Health Act for disclosure on an internet website and also file the list of chemicals with the Texas Railroad Commission with the well completion report. The total volume of water used to hydraulically fracture a well must also be disclosed to the public and filed with the Texas Railroad Commission. Further, in May 2013, the Texas Railroad Commission issued a well integrity rule, which updates the requirements for drilling, putting pipe down, and cementing wells. The rule also includes new testing and reporting requirements, such as: (i) the requirement to submit cementing reports after well completion or after cessation of drilling, whichever is later; and (ii) the imposition of additional testing on wells less than 1,000 feet below usable groundwater. These existing or any new legal requirements regulating or prohibiting the time, place and manner of drilling activities in general or hydraulic fracturing activities in particular, will likely result in added costs to comply and affect the operators’ rate of production. In some instances, the operation of underground injection wells has been alleged to cause earthquakes. Such issues have sometimes led to orders prohibiting continued injection or the suspension of drilling in certain wells identified as possible sources of seismic activity. For example, Oklahoma, New Mexico and Texas have imposed certain limits on the permitting or operation of disposal wells in areas with increased instances of induced seismic events. Future orders or regulations addressing concerns about seismic activity from well injection could affect operations on the acreage underlying our mineral interests or our equity method investment. 13
There has been increasing public controversy regarding hydraulic fracturing with regard to water, including the use of a significant amount of water, impacts on drinking water and the potential for impacts to surface water and groundwater. The inability of the operators of the acreage underlying our mineral interests to locate sufficient amounts of water or dispose of or recycle water used in their drilling and production operations could adversely impact their operations. Moreover, a number of lawsuits and enforcement actions have been initiated across the country implicating hydraulic fracturing practices. If hydraulic fracturing is further regulated at the federal or state level, fracturing activities could become subject to additional permitting and financial assurance requirements, more stringent construction specifications, increased monitoring, reporting and recordkeeping obligations, plugging and abandonment requirements and also to attendant permitting delays and potential increases in costs. In addition to state laws, local land use restrictions, such as city ordinances, may restrict or prohibit the performance of well drilling in general or hydraulic fracturing in particular. We cannot predict what additional state or local requirements may be imposed in the future on oil and gas operations in the states where we own interests. In the event state, local, or municipal legal restrictions are adopted in areas where operators that produce our oil and gas conduct operations, those operators may incur substantial costs to comply with these requirements, experience delays, or curtailment, in the pursuit of exploration, development, or production activities and perhaps even be precluded from the drilling of wells. Natural Gas and Oil Sales and Transportation The availability, terms and cost of transportation significantly affect sales of oil and natural gas. The interstate transportation of oil and natural gas and the sale or resale of natural gas is subject to federal regulation, including regulation of the terms, conditions and rates for interstate transportation, storage and various other matters, primarily by the Federal Energy Regulatory Commission (FERC). Federal and state regulations govern the price and terms for access to oil and natural gas pipeline transportation. FERC’s regulations for interstate oil and natural gas transmission in some circumstances may also affect the intrastate transportation of oil and natural gas. Although oil and natural gas prices are currently unregulated, Congress historically has been active in the area of oil and natural gas regulation. We cannot predict whether new legislation to regulate oil and natural gas might be proposed, or what proposals, if any, might be enacted by Congress or the various state legislatures. Other Laws and Regulations On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was signed into law. The OBBBA includes changes to U.S. tax law including provisions for bonus depreciation, current expensing of research expenditures and changes to the interest deductibility threshold. The changes resulting from the tax provisions in OBBBA are not expected to have a material impact on our results of operations. The OBBBA includes substantial changes to U.S. solar energy tax policy which could have a material impact on the projects being developed by ReGen Resources. Current projects in development include solar arrays, solar-gas hybrid projects, thermal generation and carbon capture primarily on reclaimed mining properties in Louisiana, Mississippi, Ohio, Pennsylvania and Texas. ReGen develops energy infrastructure projects directly as well as through joint ventures. Our investments in solar projects are dependent, in part, on federal tax incentives to preserve economic value. We believe all current solar projects have been safe harbored in order to preserve tax credit eligibility. We have approximately $8.4 million of capitalized assets associated with our solar projects. We have incurred, and will continue to incur, costs in connection with these projects and the results of operations and/or return on investment could be lower than anticipated. The United States has enacted and proposed to enact significant new tariffs. Additionally, President Trump has directed various federal agencies to further evaluate key aspects of U.S. trade policy and there has been ongoing discussion and commentary regarding potential significant changes to U.S. trade policies, treaties, and tariffs. While in February 2026 the SCOTUS limited the ability of the President of the United States to implement certain tariffs without the express authorization of Congress, there continues to exist significant uncertainty about the future relationship between the U.S. and other countries with respect to such trade policies, treaties, and tariffs.These developments, or the perception that any such policies, treaties, or tariffs could be implemented, could restrict our access to suppliers and increase the cost of equipment and supplies imported into the U.S. 14
INFORMATION ABOUT OUR EXECUTIVE OFFICERS The following tables set forth as of March 1, 2026 the name, age, current position and principal occupation and employment during the past five years of our executive officers.

Patrick Sullivan, Jr. 67 Senior Vice President and Chief Financial Officer of NNRC (from prior to 2020) Item 1A. RISK FACTORS We operate in a rapidly changing environment that involves a number of risks. The following discussion highlights some of these risks and others are discussed elsewhere in this report. These and other risks could materially and adversely affect our business, financial condition, operating results or cash flows. The following risk factors are not an exhaustive list of the risks associated with our business. New factors may emerge or changes to these risks could occur that could materially affect our business. See Item 1. Business — Government Regulation and Environmental Matters on page 9 in this Form 10-K for discussion of regulations that could materially adversely affect our businesses. Risks related to the Utility Coal Mining segment MLMC is subject to risks associated with our capital investment, operating and equipment costs, changes in customer demand and inflationary adjustments. Profitability at MLMC is affected by customer demand for coal, changes in the contractually determined sales price and actual costs incurred. The MLMC contract is the only coal supply contract in which we are responsible for all operating costs, capital requirements and final mine reclamation. As such, increased costs or decreased revenues could materially reduce our profitability. As a significant portion of MLMC’s costs are fixed, reduction in dispatch and/or reduced mechanical availability of the Red Hills Power Plant can and historically has materially reduced operating results at MLMC. Conversely, periods of higher dispatch can improve results. In February 2026, MLMC received notice from its customer that the Red Hills Power Plant experienced an unplanned outage, which is expected to lead to reduced demand and an anticipated operating loss for MLMC during 2026. Any reduction in customer demand at MLMC, including fluctuations in demand due to planned and unplanned outages at the customer's Red Hills Power Plant, unanticipated weather conditions, economic conditions, governmental regulations and inflationary adjustments could have a material adverse effect on MLMC's financial condition, results of operations and cash flows. 15
Termination of or default under long-term mining contracts could adversely affect our business, financial condition, results of operation and cash flows. Substantially all of the Utility Coal Mining segment's profits are derived from long-term mining contracts. Although we have long-term contracts, any customer's premature facility closure or contract default could have a material adverse effect on our business, financial condition and results of operations. The coal mining industry is subject to ongoing complex governmental regulations and legislation that could adversely impact our long-term mining contracts and our results of operations, liquidity, financial condition and cash flow. The coal mining industry and the electric generation industry are subject to extensive regulation by federal, state and local authorities on matters concerning the health and safety of employees, land use, stream and wetland protection, permit and licensing requirements, air and water quality standards, plant and wildlife protection, reclamation and restoration of mining properties after mining, the discharge of GHGs and other materials into the environment and the effects that mining has on groundwater quality and availability. Legislation mandating certain benefits for current and retired coal miners also affects the industry. Mining operations require numerous governmental and regulatory permits and approvals. We are required to prepare and present to federal, state or local authorities data pertaining to the impact the production and combustion of coal may have upon the environment. The public, including non-governmental organizations, opposition groups and individuals, have statutory rights to comment upon and submit objections to requested permits and approvals and to legally challenge certain permits subsequent to their issuance. Compliance with these requirements is costly and time-consuming and may delay commencement or continuation of development or production. New legislation and/or regulations and orders may materially adversely affect our mining operations, cost structure or customers. All of these factors could significantly reduce our profitability. The potential impact of future laws, regulations or other policies or circumstances will depend upon the degree to which any such laws, regulations or other policies or circumstances require electricity generators to diminish their reliance on coal as a fuel source. Complicating these matters further, over the last several decades, U.S. Administrations have increasingly relied on regulations and executive orders to implement environmental policies and objectives in the absence of Congressional agreement regarding new legislation. This condition, which creates instability and unpredictability of environmental regulations, seems likely to persist and could increase due to apparent polarization between the two main political parties. As a result, we and/or our customers, often must comply with and otherwise adapt to environmental regulations without assurance of their continued effect. We and/or our customers often do not have the ability to anticipate, or prepare in advance for, changes in regulatory approaches that may be implemented following a change in Administration. In view of the significant uncertainty surrounding each of these factors, it is not possible for us to reasonably predict the impact that any such laws, regulations or other policies may have on our business, financial condition and results of operations. However, such impacts could have a material adverse effect on our business, financial condition and results of operations. The loss of, or significant reduction in, purchases by NACCO's coal customers could adversely affect our business, financial condition, results of operation and cash flows. Earnings from the Utility Coal Mining segment's customers may fluctuate from time to time based on numerous factors, including market conditions and the realignment of customers' power generation portfolios that reduce the electric power generated from coal, which may be outside of our control. If any of the Utility Coal Mining segment's customers experience declining demand due to market, economic, regulatory or competitive conditions, it could have an adverse effect on our profitability, cash flows and financial position. In addition, if any customers were to significantly reduce or eliminate their purchases of coal from us or if we are unable to renew expiring long-term sales agreements with existing customers or enter into new supply agreements, our business, financial condition, results of operations and cash flows could be adversely affected. The Utility Coal Mining segment's Unconsolidated Subsidiaries are subject to risks created by changes in customer demand and inflationary adjustments. The contracts with the Unconsolidated Subsidiaries' customers are primarily based on a management fee approach, whereby compensation includes reimbursement of all operating costs, plus a fee based on the amount of coal delivered. The fees earned adjust over time in line with various indices which reflect general U.S. inflation rates. During the production stage, the Unconsolidated Subsidiaries' customers pay us our agreed upon fee only for the coal delivered to them for consumption or use. As a result, reduced coal usage by customers for any reason, including, but not limited to, reduced availability of the customer’s power plant, dispatch of power generated by other energy sources, fluctuations in demand due to unanticipated weather conditions, planned and unplanned outages at the Utility Coal Mining segment's customers' facilities, economic conditions and governmental regulations could have a material adverse effect on our results of operations. Because of the contractual price formulas for the management fees at these Unconsolidated Subsidiaries, the profitability of these operations is also subject to fluctuations in inflationary adjustments (or lack thereof) that can impact the agreed upon management fees. These factors could materially reduce our profitability. 16
Changes in coal consumption patterns of U.S. electric power generators could adversely affect our profitability. The amount of coal consumed by the electric power generation industry is affected by general economic conditions; overall demand for electricity; availability of transmission; competition from alternative fuel sources for power generation, such as natural gas, nuclear, hydroelectric, wind and solar power, and the location, availability, quality and price of those alternative fuel sources; and environmental and other governmental regulations. Changes in the utility industry that affect NACCO's customers could also adversely affect us. Any of these risks could result in a decrease in coal consumption by our customers and could have a material adverse effect on our business, financial condition and results of operations. We are subject to burdensome federal and state mining regulations and the assumptions underlying our reclamation and mine closure obligations could be materially inaccurate. Federal and state statutes require us to restore mine property in accordance with specified standards and an approved reclamation plan, and require that we obtain and periodically renew permits for mining operations. Regulations require us to incur the cost of reclaiming current mine disturbance at operations where we hold the mining permit. Estimates of our total reclamation and mine closing liabilities are based upon permit requirements and our engineering expertise related to these requirements. While management regularly reviews the estimated reclamation liabilities and believes that appropriate accruals have been recorded for all expected reclamation and other costs associated with closed mines, the estimate can change significantly if actual costs vary from assumptions or if governmental regulations change significantly. Such changes could have a material adverse effect on our business and could significantly reduce our profitability. The Utility Coal Mining segment's customers' operations require significant capital expenditures. Maintaining power plants requires significant capital expenditures. Any delay or reduction in making capital expenditures to maintain or upgrade coal-fired power plants by the Utility Coal Mining segment's customers, principally electric utilities, could result in an increase in outage days and a corresponding decrease in coal consumption. The Red Hills Power Plant operated at below full baseload capacity and experienced periods of reduced mechanical availability during 2024 and 2025. A decrease in coal consumption could have a material adverse effect on the Utility Coal Mining segment's financial condition, results of operations and cash flows. We face numerous uncertainties in estimating economically recoverable reserves and resources, and inaccuracies in estimates could result in lower than expected revenues, higher than expected costs and decreased profitability. Information concerning our mining operations in Item 2 - Properties on page 25 has been prepared in accordance with the requirements of subpart 1300 of Regulation S-K. A mineral is economically recoverable when the price at which it can be sold exceeds the costs and expenses of mining, processing and selling the mineral. Forecasts of NACCO's future performance are based on, among other things, estimates of mineral reserves and resources. Mineral reserve and resource estimates of the remaining tons of coal at MLMC are based on many factors, including engineering, economic and geological data assembled and analyzed by internal staff, which includes various engineers and geologists, the area and volume covered by mining rights, assumptions regarding extraction rates and duration of mining operations, and the quality of in-place reserves and resources. The reserve and resource estimates as to both quantity and quality are updated from time to time to reflect, among other matters, production of minerals, new mining or other data received. There are numerous uncertainties inherent in estimating quantities and qualities of minerals and costs to mine recoverable reserves and resources, including many factors beyond our control. While we believe that our mineral reserve and resource estimates are developed using well-established practices and with appropriate controls, mineral reserve and mineral resource estimation is an imprecise and subjective process. Estimates of mineral reserves and resources depend upon a number of variable factors and assumptions, any one of which may, if incorrect, result in an estimate that varies considerably from actual results. These factors and assumptions include: • Geologic and mining conditions, including our ability to access certain mineral deposits as a result of the nature of the geologic formations of coal deposits or other factors, which may not be fully identified by available exploration data and may differ from past experience; • Demand for our minerals; • Contractual arrangements, operating costs and capital expenditures; • Development and reclamation costs; • Mining technology and processing improvements; • The effects of regulation by governmental agencies, including volatility in the political, legal and regulatory environments due to the U.S. presidential administration; • The ability to obtain, maintain and renew all required permits; • Employee health and safety; and • Our ability to convert all or any part of mineral resources to economically extractable mineral reserves. 17
As a result, actual tonnage recovered, estimated revenues, expenditures and cash flows with respect to reserves and resources may vary materially from estimates. Thus, these estimates may not accurately reflect our actual reserves and resources. Any material inaccuracy in estimates related to our reserves or resources could result in lower than expected revenues, higher than expected costs or decreased profitability and changes in future cash flow, which could materially and adversely affect our business, results of operations, financial position and cash flows. Additionally, reserve and resource estimates may be adversely affected in the future by interpretations of, or changes to, the SEC’s property disclosure requirements for mining companies. A defect in title or the loss of a leasehold interest in certain property could limit our ability to mine coal reserves or result in significant unanticipated costs. We conduct a significant part of our coal mining operations on leased properties. A title defect or the loss of a lease could adversely affect the ability to mine the associated coal reserves. We may not verify title to leased properties or associated coal reserves until we are committed to developing those properties or coal reserves. We may not commit to develop property or coal reserves until we have obtained necessary permits and completed exploration. As such, the title to property that we intend to lease or mine may contain defects prohibiting the ability to conduct mining operations. Similarly, leasehold interests may be subject to superior property rights of third parties. In order to conduct mining operations on properties where these defects exist, we may incur unanticipated costs. In addition, some leases require us to produce a minimum quantity of coal and/or pay minimum production royalties. Our inability to satisfy those requirements may cause the leasehold interest to terminate. Risks related to the Contract Mining segment We have experienced growth in our Contract Mining business in recent periods and we may not be able to sustain growth or manage future growth effectively. We have expanded our overall Contract Mining business, operations and headcount in recent periods. The Contract Mining segment's operating expenses may increase as we continue to scale the Contract Mining business. We must effectively integrate, develop and motivate employees, while integrating new equipment and customers in an efficient and effective manner. We anticipate that we will continue to incur costs and capital expenditures associated with future growth prior to realizing the full measure of anticipated long-term benefits, and the return on these investments may be lower, may develop more slowly than expected or may never be realized. If we are unable to manage this growth and the associated expenses effectively, we may not be able to take advantage of market opportunities or remain competitive. We may also fail to execute on our business plan or respond to competitive pressures, any of which could adversely affect the Contract Mining business, operating results and financial condition. Our Contract Mining business faces competition from customers that choose to self-perform mining operations and from other mining companies. We face competition from existing and prospective customers that are capable of performing, or engaging other companies to perform the services we provide. We cannot be certain that our existing customers will continue to outsource these services to us in the future, which could adversely affect the Contract Mining business, operating results and financial condition. We are subject to risks involved in the development of new mining projects. From time to time, we seek to develop new mining projects, including the Thacker Pass project. The risks associated with such projects can be substantial. New mining projects can take up to several years to complete, are complex and require significant capital expenditures. These projects are subject to significant risks, including delays or reductions in making capital expenditures by Contract Mining's customers, timely regulatory approvals, extreme weather events, unexpected increases in the cost of required materials, and disputes with third party providers of materials, equipment or services, and a completed project may not yield the anticipated operational or financial benefit, any of which could have a material adverse effect on our business, financial condition and results of operations. Contract Mining operations are currently geographically concentrated and therefore subject to regional economic risk, regulatory conditions, natural disasters, severe weather events or other circumstances affecting Florida. As of December 31, 2025, over 80% of the Contract Mining segment's quarries are located in Florida. A prolonged economic downturn or adverse change in regulatory conditions in the Florida mining or construction industry could result in a significant reduction in demand for our services. The occurrence of one or more natural disasters, severe weather events, terrorist attacks, or disruptive political events in Florida could adversely affect the Contract Mining business. 18
Risks related to the Minerals and Royalties segment We have no control over the timing of the development and operation of our natural gas, oil and coal reserves extracted by third parties. We own mineral and royalty interests in the continental United States. The Minerals and Royalties segment does not currently have any material investments under which it would be required to bear the cost of exploration, production or development. We primarily derive income from royalty-based leases under which lessees make payments to us based on their sale of natural gas, oil and coal. Future royalty-based income is dependent on the number of oil and gas wells being developed and operated on our mineral acreage. The decision to pursue development and operation of oil and gas wells is made by third-party operators, not by us, and depends on a number of factors outside of our control, including fluctuations in commodity prices, regulatory risk, our lessees' willingness and ability to incur well-development and other operating costs, the rate of production of the reserves and changes in the availability and continuing development of infrastructure. Lower commodity prices and/or increased costs may reduce the amount of oil and natural gas that third-party operators can produce economically. In addition, if a lessee were to experience financial difficulty, the lessee might not be able to pay our royalty payments or continue operations. A failure on the part of the lessee to make royalty payments may give us certain rights; and if possible, we would seek a replacement lessee. However, we may not be able to find a replacement lessee or might not be able to enter into a new lease on favorable terms within a reasonable period of time. In addition, if we are able to enter into a new lease with a new lessee, the replacement lessee may not achieve the same levels of production or sales prices as the lessee it replaced. Any of these risks could materially reduce our expected royalty income and profitability. Minerals are a depleting asset. Unless we replace existing mineral and royalty interests with new mineral and royalty interests and third-party lessees develop those mineral and royalty interests, our reserves and royalty income will decline. Producing oil and natural gas reservoirs are generally characterized by declining production rates that vary depending upon reservoir characteristics and other factors. Unless our third-party lessees conduct successful ongoing well development activities or we continually acquire mineral and royalty interests, production and income related to our mineral and royalty interests will decline as those reserves are depleted. The future cash flow and results of operations of the Minerals and Royalties segment are highly dependent on third-party operators’ success in developing our current and future mineral and royalty interests. These operators may not have access to the capital needed to develop our mineral interests. We may not be able to acquire or find sufficient additional mineral and royalty interests to replace third-party operators' current and future production. Further, the decline curve we use to project future royalty income is subject to numerous assumptions and limitations. Decline rates can vary due to factors like well depth, well length, formation pressure and facility design. Any of these risks could materially reduce our expected royalty income and profitability. Substantially all of the Minerals and Royalties segment’s revenues are derived from royalty payments that are based on the price at which oil and natural gas produced from the acreage underlying our interests are sold. Prices of oil and natural gas are volatile due to factors beyond our control. A substantial or extended decline in commodity prices may adversely affect the Minerals and Royalties segment’s financial condition or results of operations. The Minerals and Royalties segment’s revenues and operating results depend significantly upon the prevailing prices for oil and natural gas. Historically, oil and natural gas prices have been volatile and are subject to fluctuations in response to changes in: supply and demand, including if energy supply exceeds demand; market uncertainty and a variety of additional factors that are beyond our control; market expectations about future prices of oil and natural gas; the level of global oil and natural gas exploration and production; the cost of exploring for, developing, producing and delivering oil and natural gas; the price and quantity of foreign imports and U.S. exports of oil and natural gas; the level of U.S. domestic production; political and economic conditions in oil producing regions; the ability of members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls; trading in oil and natural gas derivative contracts; the level of consumer product demand; weather conditions and natural disasters; technological advances affecting energy consumption, energy storage and energy supply; domestic and foreign governmental regulations and taxes; the continued threat of terrorism and the impact of military and other action, including ongoing conflicts in foreign nations and associated oil and natural gas import bans as well as economic sanctions; the proximity, cost, availability and capacity of oil and natural gas pipelines and other transportation facilities; the price and availability of alternative fuels; volatility in the political, legal and regulatory environments; and overall domestic and global economic conditions. A substantial or extended decline in commodity prices may adversely affect the Minerals and Royalties segment’s financial condition or results of operations. The marketability of oil and natural gas production is dependent upon transportation, pipelines and refining facilities and continued operation of the U.S. power grid. Any limitation in the availability of these items could interfere with our third-party lessee’s ability to market oil and natural gas production and may adversely affect the Minerals and Royalties segment’s financial condition or results of operations. 19
The marketability of our third-party lessee’s production depends in part on the availability, proximity, and capacity of pipelines, tanker trucks, and other transportation methods, and processing and refining facilities owned by third parties as well as continued reliable operation of the U.S power grid. Any significant disruption in the U.S. power grid, gathering system or transportation, processing, or refining-facility capacity could reduce our third-party lessee’s ability to market oil production and may adversely affect the Minerals and Royalties segment’s financial condition or results of operations. Risks related to long-term growth strategy Our investments in mitigation solutions, comprehensive reclamation and restoration construction services as well as solar and other energy-related development projects are subject to substantial risks and uncertainties. There are risks associated with NACCO's ability to execute on our longer term growth strategy, including our investment in mitigation solutions, comprehensive reclamation and restoration construction services as well as other energy-related projects through our Mitigation Resources of North America and ReGen Resources businesses, and our ability to develop and manage such projects profitably. These include political and regulatory developments that may make it more costly, or impossible, to pursue these business opportunities, logistical risks and potential delays related to construction, permitting and regulatory approvals; operational risk that the projects will not perform according to expectations; weather conditions or other factors beyond our control. General concerns about the fundamental soundness of the economy may cause customers to defer projects, even if they have available financing. Prolonged uncertainties in the capital markets, or the returns of constrained capital market conditions, could have adverse effects on our customers. All of the aforementioned risks could reduce the viability of project development, which would adversely affect our financial condition and results of operations. The OBBBA includes substantial changes to U.S. solar energy tax policy which could have a material impact on the projects being developed by ReGen Resources. Current projects in development include solar arrays, solar-gas hybrid projects, thermal generation and carbon capture primarily on reclaimed mining properties in Louisiana, Mississippi, Ohio, Pennsylvania and Texas. ReGen develops energy infrastructure projects directly as well as through joint ventures. Our investments in solar projects are dependent, in part, on federal tax incentives to preserve economic value. We believe all current solar projects have been safe harbored in order to preserve tax credit eligibility. We have approximately $8.4 million of capitalized assets associated with our solar projects. We have incurred, and will continue to incur, costs in connection with these projects and the results of operations and/or return on investment could be lower than anticipated. These projects face the risk that the current state regulatory programs and tax laws may expire or be adversely modified and could have a material adverse effect on our operating results and financial condition. Operating results may vary significantly from period to period and are inherently unpredictable. Demand for our mitigation credits and mitigation services has been, and will likely continue to be, cyclical in nature and vulnerable to downturns in the general economy, as well as downturns in government infrastructure spending. We base our planned operating expenses in part on our expectations of future revenue, and a significant portion of our expenses are fixed in the short-term. We have and will continue to incur costs in connection with these projects and the results of operations and/or return on investment could be negative or lower than anticipated and we may need to write-down the value of capitalized assets associated with these projects. Furthermore, our ability to forecast results may be hindered or inaccurate and the projects may not perform as predicted. Even if these projects are profitable in the long term, they may not be profitable in the short term, and results of operations will not be even quarter over quarter, and this could have a material adverse effect on our operating results and financial condition. Risks related to corporate structure The amount and frequency of dividend payments made on NACCO's common stock could change. The Board of Directors has the power to determine the amount and frequency of the payment of dividends. Decisions regarding whether or not to pay dividends and the amount of any dividends are based on earnings, capital and future expense requirements, financial conditions and other factors the Board of Directors may consider. Accordingly, holders of our common stock should not rely on past payments of dividends in a particular amount as an indication of the amount of dividends that will be paid in the future. The price of NACCO's securities may be volatile. The price of our common stock may fluctuate due to a variety of market and industry factors that may materially reduce the market price of NACCO's common stock regardless of operating performance, including, among others: (i) actual or anticipated fluctuations in our quarterly and annual results and those of other public companies in the industry; (ii) industry cycles and trends; (iii) changes in government regulation; (iv) military conflicts, inclusive of acts of terrorism; (v) supply chain disruptions, inclusive of tariff effects; (vi) announcements concerning NACCO, our customers or competitors; (vii) lack of trading liquidity as a result of low trading volumes could make it difficult for investors to sell shares; and (viii) the general state 20
of the securities market. In addition, the stock market in general has experienced significant volatility that often has been unrelated to the operating performance of companies whose shares are traded. These market fluctuations could adversely affect the trading price of our common stock, regardless of NACCO's actual operating performance. As a result of all of these factors, investors in our common stock may not be able to resell their stock at or above the price they paid or at all. Further, we could be the subject of securities class action litigation due to any such stock price volatility, which could divert management’s attention and have a material adverse effect on our operating results. NACCO's certificate of incorporation and by-laws include provisions that may discourage a takeover attempt. Provisions contained in our certificate of incorporation and by-laws and Delaware law could make it more difficult for a third- party to acquire us, even if doing so might be beneficial to NACCO's stockholders. Provisions in our by-laws and certificate of incorporation impose various procedural and other requirements that could make it more difficult for stockholders to affect certain corporate actions. These provisions could limit the price that certain investors might be willing to pay in the future for shares of our common stock and may have the effect of delaying or preventing a change in control. Our stock repurchase program could affect the price of NACCO’s common stock and increase volatility and may not enhance long-term shareholder value. Our Board of Directors has authorized a stock repurchase program. The timing and amount of any repurchases under the stock repurchase program are determined at the discretion of our management based on a number of factors, including the availability of capital, other capital allocation alternatives, market conditions for our Class A common stock and other legal and contractual restrictions. The stock repurchase program does not require us to acquire any specific number of shares and may be modified, suspended, extended or terminated without prior notice and may be executed through open market purchases, privately negotiated transactions or otherwise. Repurchases under the stock repurchase program could affect the price of our Class A common stock. The existence of a stock repurchase program could cause the price of our Class A common stock to be higher than it would be in the absence of such a program and could potentially reduce the market liquidity for our Class A common stock. There can be no assurance that any stock repurchases will enhance shareholder value because the market price of our Class A common stock may decline below the levels at which we repurchased the shares. Although the stock repurchase program is intended to enhance long-term shareholder value, there is no assurance that it will do so and short-term price fluctuations in the Class A common stock could reduce the program’s effectiveness. Furthermore, the stock repurchase program does not obligate us to repurchase any dollar amount or number of shares of our Class A common stock, and it may be suspended or discontinued at any time and any suspension or discontinuation could cause the market price of our Class A common stock to decline. NACCO is a smaller reporting company and cannot be certain if the reduced disclosure requirements applicable to smaller reporting companies will make our common stock less attractive to investors. We are currently a smaller reporting company as defined in the Securities Exchange Act of 1934, and thus allowed to provide simplified executive compensation disclosures and other decreased disclosure in SEC filings. The reduced disclosures may make it more difficult to compare our performance with other public companies. NACCO cannot predict whether investors will find our common stock less attractive because of these exemptions. If some investors find NACCO's common stock less attractive as a result, there may be a less active trading market for our common stock and the stock price may be more volatile. Certain members of our extended founding family own a substantial amount of our Class A and Class B common stock and, if they were to act in concert, could control the outcome of director elections and other stockholder votes on significant corporate actions. We have two classes of common stock: Class A common stock and Class B common stock. Holders of Class A common stock are entitled to cast one vote per share and, as of December 31, 2025, accounted for approximately 27 percent of our voting power. Holders of Class B common stock are entitled to cast ten votes per share and, as of December 31, 2025, accounted for our remaining voting power. As of December 31, 2025, certain members of our extended founding family held approximately 35 percent of our outstanding Class A common stock and approximately 99 percent of our outstanding Class B common stock. On the basis of this common stock ownership, certain members of our extended founding family could have exercised approximately 81 percent of our total voting power. Although there is no voting agreement among such extended family members, in writing or otherwise, if they were to act in concert, they could control the outcome of director elections and other stockholder votes on significant corporate actions, such as certain amendments to our certificate of incorporation and our sale or the sale of our assets. Because certain members of our extended founding family could prevent other stockholders from exercising significant influence over significant corporate actions, we may be a less attractive takeover target, which could adversely affect the market price of our common stock. 21
General Risk Factors Our effective income tax rate could be volatile and materially change as a result of changes in tax laws, mix of earnings and other factors. We are subject to income taxes in the United States and the effective income tax rate is impacted by certain U.S. federal income tax benefits currently available to coal mining and oil and gas exploration and development companies. Future results of operations could be affected by changes in our effective income tax rate as a result of an increase in the statutory tax rate or the reduction or elimination of percentage depletion as well as changes in the mix of earnings between entities that benefit from percentage depletion and those that do not. Current and future capital and credit market conditions could adversely affect our ability to obtain bank financing on reasonable terms. We may be unable to obtain financing on reasonable terms. Historically, we have addressed our liquidity needs (including funds required to pay dividends and fund working capital and planned capital expenditures) with operating cash flow and borrowings under credit facilities. Our wholly-owned subsidiary has a revolving line of credit of up to $200.0 million that expires in September 2028. Our ability to access the capital markets and the costs and terms of available financing depends on many factors. An inability to obtain bank financing, or refinance with terms that are as favorable as the existing terms of such indebtedness, could have a material adverse effect on our operating results and financial condition. Failure to obtain financial assurance to secure reclamation and other long-term obligations, including surety bonds and letters of credit on acceptable terms, could affect NACCO's ability to mine. Federal and state laws require us to provide financial assurance or financial security to secure performance or payment of certain long-term obligations, such as mine closure or reclamation costs, federal and state workers’ compensation and black lung benefit costs, leases, transmission interconnection construction costs, power purchase agreement delivery obligations and other obligations. Future federal and state laws and regulations, regional transmission organizations and power purchase agreement customers may require higher amounts of financial security, including as a result of changes to certain factors used to calculate the bonding or security amounts. Bond issuers may demand higher fees or additional collateral, including cash or letters of credit or other terms less favorable upon renewals. As we are required by state and federal law to have bonds or other acceptable security in place before mining can commence or for certain projects to move forward, the failure to maintain surety bonds, letters of credit or other guarantees or security arrangements would materially and adversely affect NACCO's ability to mine. That failure could result from a variety of factors, including lack of availability, higher expense or unfavorable market terms, the exercise by third-party surety bond issuers of their right to refuse to renew the surety and restrictions on availability of collateral for current and future third-party surety bond issuers under the terms of our financing arrangements. Any such factors, could have a material adverse impact on our liquidity and financial position. If we are unable to meet collateral requirements and cannot otherwise obtain or retain required surety bonds, it may be unable to satisfy legal requirements necessary to conduct mining operations. Difficulty in acquiring surety bonds, or additional collateral requirements, would increase our costs and likely require greater use of alternative sources of funding for this purpose, which would reduce our liquidity. Insurance coverage is increasingly expensive, contains more stringent terms and may be difficult to obtain in the future. We hold a number of insurance policies, including director and officers’ liability and property and casualty insurance coverages. If we make significant insurance claims under our insurance policies, such claims may have a material adverse effect on our ability to obtain future insurance coverage at commercially reasonable rates. Limited, or an inability to obtain, insurance coverage, significant increases in the premiums or deductibles of insurance, or losses in excess of our liability insurance coverage limits, could have a material adverse effect on our operating results and financial condition. We may be subject to litigation seeking to hold energy companies accountable for the effects of climate change. Increasing attention to climate change risk has also resulted in a recent trend of governmental investigations and private litigation by local and state governmental agencies as well as private plaintiffs in an effort to hold energy companies accountable for the alleged effects of climate change. Other public nuisance lawsuits have been brought in the past against power, coal, oil and gas companies alleging that their operations are contributing to climate change. We could incur substantial legal costs associated with defending such lawsuits in the future. Government entities in certain states have brought similar claims seeking to hold a wide variety of companies that produce fossil fuels liable for the alleged impacts of emissions attributable to those fuels or for other grounds related to climate change, such as improper disclosure of climate change risks. Those lawsuits allege damages as a result of climate change and the plaintiffs are seeking unspecified damages and abatement under various tort theories. We have not been made a party to these suits, but it is possible that we could be included in similar future lawsuits initiated by state and local governments as well as private claimants. 22
Our business could suffer if NACCO’s information technology systems are disrupted, cease to operate effectively or if we experience a security breach, a cyber incident or cyber attack. Like many other companies, we are the target of malicious cyber attack attempts in the normal course of business. Cybersecurity incidents involving businesses and other institutions are on the rise. Cyber threats are rapidly evolving and those threats and the means for obtaining access to information in digital and other storage media are becoming increasingly sophisticated. Cyber threats and cyber attackers can be sponsored by nation states or sophisticated criminal organizations or be the work of independent hackers. The rapid evolution and increased availability of artificial intelligence (AI) may intensify cybersecurity risks by making cyber-attacks more sophisticated and cybersecurity incidents more difficult to detect, contain and mitigate. As threat actors adopt and deploy AI tools, the speed and sophistication of cyber threats and privacy risks may increase across our environment and those of our customers and vendors. Employee error or other irregularities may also result in a failure of security measures and a breach of information systems. Moreover, hardware, software or applications we may use have inherent defects of design, manufacture or operations or could be inadvertently or intentionally implemented or used in a manner that could compromise information security. A security breach and loss of information may not be discovered for a significant period of time after it occurs. Any compromise of data security could result in a violation of applicable privacy and other laws or standards, the loss of valuable business data, or a disruption of our business. A security breach involving the misappropriation, loss or other unauthorized disclosure of sensitive or confidential information could give rise to unwanted media attention, materially damage customer relationships and our reputation, and result in fines, fees, or liabilities, which may not be covered by insurance policies. We rely on information technology systems to operate our business and to record and process transactions; respond to customer inquiries; purchase supplies; provide services; deliver inventory on a timely basis; and maintain cost-efficient operations. Despite our efforts, our information technology systems may be vulnerable, from time to time, to damage or interruption from user error, computer viruses, power outages, third-party intrusions and other technical malfunctions. Through our business operations, we collect and store confidential information from our customers and vendors and personal information and other confidential information from our employees. Although we have taken steps designed to safeguard such information, there can be no assurance that such information will be protected against unauthorized access, use or disclosure. Unauthorized parties may penetrate our or our vendors’ network security and, if successful, misappropriate such information. Additionally, methods to obtain unauthorized access to confidential information change frequently and may be difficult to detect, which can impact our ability to respond appropriately. We could be subject to liability for failure to comply with privacy and information security laws, for failing to protect personal information or for failing to respond appropriately. Loss, unauthorized access to, or misuse of confidential or personal information could disrupt our operations, damage our reputation, and expose us to claims from customers, financial institutions, regulators, employees and other persons, any of which could have an adverse effect on our business, financial condition and results of operations. Security breaches, cyber incidents or cyber attacks could include, among other things, computer viruses, malicious or destructive code, ransomware, social engineering attacks (including phishing and impersonation), hacking, denial of service attacks and other attacks. Cybersecurity threats to, and incidents involving, vendors and other third-parties who support our activities could impact the business. We are continuously installing new and upgrading existing information technology systems. We use employee awareness training around phishing, malware, and other cyber risks. We believe these incidents are likely to continue and are unable to predict the direct or indirect impact of future attacks or breaches to business operations. Our operations could be disrupted by natural or human causes beyond our control. Our operations are subject to disruption from natural or human causes beyond our control, including physical risks from hurricanes, severe storms, floods and other forms of severe weather, accidents, fires, earthquakes, terrorist acts and epidemic or pandemic diseases, any of which could result in suspension of operations or harm to people or the environment. While all of our operations are located in the United States, we participate in a global supply chain, and if governments regulate or restrict the flow of labor or products or impede the travel of our personnel, our ability to conduct normal business operations could be impacted which could adversely affect our results of operations and liquidity.

Item 1C. CYBERSECURITY Cybersecurity continues to be a key governance priority for us. NACCO maintains a cybersecurity program that is aligned with our business and has established policies and processes for assessing, identifying, and managing material risk from cybersecurity threats, which have been integrated into our overall risk management processes and governance structure. We have implemented and invested in, and will continue to implement and invest in, controls, technologies, and resources (both internal and external) that are designed to identify, protect against, detect, respond to and mitigate cybersecurity risks, in alignment with frameworks established by the National Institute of Standards and Technology. These include, but are not limited to, internal reporting mechanisms, monitoring and detection tools, threat intelligence, and general and role-based training. NACCO's commitment to cybersecurity emphasizes cultivating a security-minded culture through education and training that reflect best practices and improved cybersecurity awareness. We also maintain third party management processes to identify and manage the cybersecurity risks associated with third party service providers. We periodically evaluate our cybersecurity program internally and by engaging with consultants to conduct reviews and assessments of the program. Such reviews and assessments may include penetration testing, maturity assessments as well as table-top and other exercises with subsequent remediation of key findings. Additionally, we have a Cybersecurity Task Force in place that is comprised of individuals across various departments within our organization including information systems, legal, finance, human resources and internal audit which meets regularly to further advance our cybersecurity strategy. Our Board of Directors (Board) oversees NACCO's risk management. Our full Board regularly reviews information provided by management to oversee risk identification, risk management and risk mitigation strategies. The Audit Review Committee assists the Board with cybersecurity risk oversight. The Audit Review Committee is responsible for regularly reviewing and discussing with management risk exposure relating to cybersecurity. This process includes reviewing the state of our cybersecurity program, discussing emerging cybersecurity developments, including AI, and monitoring the steps that management has taken to mitigate such exposure. In 2025, our Board and the Audit Review Committee received periodic updates throughout the year on cybersecurity matters and these updates are part of their standing agendas. Our Chief Information Security Officer (CISO) leads NACCO's cybersecurity program and is responsible for the management of our cybersecurity risks. The CISO has extensive cybersecurity knowledge and skills gained from over 30 years of technical and business experience, including as General Manager & President of MLMC, Vice President of Mississippi Operations and Vice President of Innovation & Technology. The CISO holds a bachelor’s degree in engineering, an executive MBA, and certifications in cybersecurity from Harvard. Additionally, the CISO successfully completed an Executive course through Northwestern’s Kellogg School of Management focused on artificial intelligence during 2024. The CISO reports directly to the President and Chief Executive Officer. The CISO manages a team of internal and external resources that have expertise and experience in cybersecurity. The CISO is informed of cybersecurity incidents by the cybersecurity team, which is generally responsible for monitoring the prevention, detection, mitigation, and remediation of cybersecurity incidents. We have an established process governing our assessment, response and internal and external notifications upon the occurrence of a cybersecurity incident, including evaluation of the potential impacts of cybersecurity incidents to determine materiality. Depending on the nature and severity of an incident, this process provides for escalation procedures upon discovery of material cybersecurity risks, including notification to our executive management and/or Board. As of the date of this filing, our business strategy, results of operations, and financial condition have not been materially impacted as a result of any previously identified cybersecurity incidents; however, NACCO cannot provide assurance that we will not be materially impacted in the future by such risks or any future material incidents. We recognize the constantly evolving nature of cyber threats and are committed to cultivating a strong security culture, maintaining vigilance and continuously enhancing our cybersecurity systems and controls. For additional information regarding our cybersecurity risks, please refer to Item 1A - Risk Factors on page 15. 24
Item 2. PROPERTIES Utility Coal Mining Segment - Operations NACCO-owned Properties 1.0 INTRODUCTION Information concerning our mining properties in this Form 10-K have been prepared in accordance with the requirements of subpart 1300 of Regulation S-K. As used in this Report on Form 10-K, the terms mineral resource, measured mineral resource, indicated mineral resource, inferred mineral resource, mineral reserve, proven mineral reserve and probable mineral reserve are defined and used in accordance with subpart 1300 of Regulation S-K. Under subpart 1300 of Regulation S-K, mineral resources may not be classified as mineral reserves unless the determination has been made by a qualified person that the mineral resources can be the basis of an economically viable project. Readers are specifically cautioned not to assume that any part or all of the mineral deposits (including any mineral resources) in these categories will ever be converted into mineral reserves, as defined by the subpart 1300 of Regulation S-K. Readers are cautioned that, except for that portion of mineral resources classified as mineral reserves, mineral resources do not have demonstrated economic value. Inferred mineral resources are estimates based on limited geological evidence and sampling and have too high of a degree of uncertainty as to their existence to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Estimates of inferred mineral resources may not be converted to a mineral reserve. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. A significant amount of exploration must be completed in order to determine whether an inferred mineral resource may be upgraded to a higher category. Therefore, readers are cautioned not to assume that all or any part of an inferred mineral resource exists, that it can be the basis of an economically viable project, or that it will ever be upgraded to a higher category. Likewise, readers are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted to mineral reserves. See Item 1A - Risk Factors on page 15. The information that follows is derived, for the most part, from, and in some instances is an extract from, the technical report summary (TRS) prepared in compliance with the Item 601(b)(96) and subpart 1300 of Regulation S-K. The TRS was prepared by certain of our employees. Portions of the following information are based on assumptions, qualifications and procedures that are not fully described herein. Reference should be made to the full text of the TRS, incorporated herein by reference and made a part of this Report on Form 10-K. The information regarding MLMC was reviewed by our employees that are qualified persons as defined by subpart 1300 of Regulation S-K. Coteau, Falkirk, Coyote Creek and MLMC, each wholly-owned subsidiaries of NACCO, operate surface coal mines under long-term contracts with power generation companies pursuant to a service-based business model. Locations of the properties subject to SEC Section 1300 reporting are shown in Figure 1.1 Surface Coal Mines Operational During 2025 Subject to SEC Section 1300 Reporting. 25
Figure 1.1 Surface Coal Mines Operational During 2025 Subject to SEC Section 1300 Reporting A summary of coal production at the Mines subject to SEC Section 1300 Reporting for the past three years has been tabulated and is presented on Table 1.1 Production Summary.

The Red Hills Mine is a lignite surface mine in production. Prior to MLMC, there were no previous mining operations on the Red Hills Mine property. The MLMC contract is the only operating coal contract in which we are responsible for all operating costs, capital requirements and final mine reclamation; therefore, MLMC is consolidated within our financial statements. MLMC sells coal to its customer at a contractually agreed-upon price which adjusts monthly, primarily based on changes in the level of established indices which reflect general U.S. inflation rates. Profitability at MLMC is affected by customer demand for coal and changes in the indices that determine sales price and actual costs incurred. 26
A summary of coal production at MLMC for the past three years has been tabulated and is presented on Table 2.1 Production Summary. Tons (in millions) 2023 2024 2025 Mississippi Lignite Mining Company 2.7 1.9 2.7 Table 2.1 Production Summary The Red Hills Mine generally produces between 2 million and 3 million tons of lignite coal annually. The Red Hills Mine started operations in 2000 for plant commissioning, with initial commercial deliveries starting in 2001, and full production and commercial deliveries starting in 2002. All production from the mine is delivered to MLMC's customer's Red Hills Power Plant. The Red Hills Mine, operated by MLMC, is located approximately 120 miles northeast of Jackson, Mississippi (Figure 2.1). The entrance to the mine is by means of a paved road located approximately one mile west of Highway 9. MLMC owns in fee approximately 8,337 acres of surface interest and 5,436 acres of coal interests. MLMC holds leases granting the right to mine approximately 4,660 acres of coal interests and the right to utilize approximately 4,384 acres of surface interests. MLMC holds subleases under which it has the right to mine approximately 1,860 acres of coal interest. The majority of the leases held by MLMC were originally acquired during the mid-1970s to the early 1980s with terms extending 50 years, many of which can be further extended by the continuation of mining operations. The lignite deposits of the Gulf Coast are found primarily in a narrow band of strata that outcrops/subcrops along the margin of the Mississippi Embayment. The potentially exploitable tertiary lignites in Mississippi are found in the Wilcox Group. The outcropping Wilcox is composed predominately of non- marine sediments deposited on a broad flat plain. The towns of Ackerman, Eupora, Starkville, Louisville, Kosciusko, and numerous smaller communities are within a 40-mile radius of the Red Hills Mine and provide a vast employment base. Furthermore, Mississippi State University (MSU) is located approximately 30 miles east of the mine in Starkville. MLMC has a history of partnership with MSU as well as the local community colleges for science, technology, engineering, and mathematics (STEM) research and skilled trades training. The Red Hills Mine sources power for mine office facilities and operations from 4-County Electric Power Association, and water for the mine office facilities from the Reform Water Association. Fuel for equipment is supplied by a local vendor. The Red Hills Mine has, or is currently constructing, all supporting infrastructure for mining operations. Local access to the Red Hills Mine is by way of Highway 9 between Ackerman, Mississippi and Eupora, Mississippi which connects to Pensacola Road that leads to the Red Hills Mine paved access road. Pensacola Road connects with Highway 9 approximately 5 miles north of Ackerman, MS. The mine road is approximately 1 mile west from Highway 9 along Pensacola Road. Travel to the Red Hills Mine by air is possible using the Jackson-Medgar Wiley Evers International Airport in Jackson, Mississippi, approximately 104 miles south of the mine, and then using ground transportation, traveling via Highway 25, Highway 15, and Highway 9. Alternatively, the Golden Triangle Regional Airport is a smaller airport approximately 50 miles from the Red Hills Mine by means of Highway 82 west, Highway 15 south, and Highway 9 north. The Red Hills Mine is in close proximity to river ports of the Tennessee-Tombigbee Waterway and the Mississippi River. The Lowndes County Port is approximately 60 miles east of the mine. The Port of Greenville is approximately 135 miles west of the mine, and the Port of Vicksburg, approximately 150 miles southwest of the mine. All ports are connected by major state and federal highways. In addition to transportation via roadways, air and waterways, the Kansas City Southern (KCS) railroad has a depot located approximately 5 miles south of the mine in Ackerman, and is accessible by Highway 9 and Highway 15. MLMC currently has all permits in place for the Red Hills Mine to operate and adhere to a mine plan projected through April 1, 2032. No mineral processing occurs at the Red Hills Mine. The geology encountered at the Red Hills Mine is stratigraphic in nature with depositional sequences of sands, silts, clays, and lignite. The vertical repetition of geologic strata facilitated a straightforward setting to establish and study the baseline geological, geochemical, geotechnical, and geohydrological conditions at the Red Hills Mine. Development of the Red Hills Mine began in 1997, with full commercial deliveries commencing in 2002. The mining operation is comprised of four major equipment fleets. Primary removal of burden is achieved with one 82-cubic yard electric-powered 27
dragline, four large track-type push dozers, and a truck and shovel fleet utilizing a 41-cubic yard electric rope shovel. Lignite is mined using a surface miner or a hydraulic backhoe to load a fleet of end dump haul trucks, and is directly shipped to the RHPP or the lignite stockpile. The overall average quality of the mined lignite seams meets the required power plant quality specifications. Therefore, no mineral processing is performed by MLMC. The mine office facilities and original equipment fleets at the Red Hills Mine were constructed, acquired, or purchased new during the development stage of the mine. The facilities and equipment are maintained to allow for safe and efficient operation. The equipment is well maintained, in good physical condition and is either updated or replaced periodically with newer models or upgrades available to keep up with modern technology. As equipment wears out, MLMC evaluates what replacement option will be the most cost-efficient, including the evaluation of both new and used equipment. The total cost of the property and equipment, net of applicable accumulated amortization, depreciation and impairment as of December 31, 2025 is $54.4 million. The Red Hills Mine currently has no significant encumbrances to the property. No mining permit violations have been issued at the Red Hills Mine in the past ten years. One notice of violation (NOV) was issued in April 2020 for a water quality exceedance that was determined to not be the fault of Red Hills Mine and no further action was required. A second NOV was issued in June 2022 for a water sampling violation. Both NOVs were not related to the mining permit. Permitting requirements are discussed in Section 17.0 of the TRS. Figure 2.1 – Red Hills Mine Location Mineral Resources and Reserves have been summarized from the December 31, 2024 TRS for MLMC and have been modified from mining depletion. The Mineral Resources and Mineral Reserves as of December 31, 2025 are included as Table 2.2 and Table 2.3. Coal qualities are reported on an as-received moisture basis. Based on the December 31, 2024 TRS, prices in Table 2.2 are based on economic cut-off grades of $34.02 per ton at MLMC and prices in Table 2.3 are based on economic cut-off grades of $34.40 per ton at MLMC. 28
Material assumptions and criteria used in the determination of Mineral Resource and Mineral Reserves reported herein are provided within the filed TRS for the MLMC – Red Hills Mine dated December 31, 2024. Section 11.0 of the TRS describes the key assumptions, parameters, and methods used for the estimation of Mineral Resources. Assumptions include a maximum cumulative stripping ratio of 18:1 based on an assumed lignite sales price of $34.02 per ton. A further description of the verified drilling data used to model the lignite deposit for estimation of Mineral Resources is provided in Section 7.2 Drilling Exploration, 8.0 Sample Preparation, Analyses, and Security, and Section 9.0 Data Verification. Section 12.0 of the TRS describes the key assumptions, parameters, and methods used for the estimation of Mineral Reserves, and include the following: • Maximum stripping ratio: 14:1; • Mining production rates on a cubic yard and per ton basis remain relatively consistent with historical performance; • Mining costs on a unit basis remain relatively consistent with historical performance; • Minimum minable lignite thickness: 1.0 feet; • Minimum parting thickness before seams are composited: 6.0 inches; • Maximum depth of mining: approximately 320 feet; • Lignite density defined by seam from coal core drilling data and modified by dilution parameters and approximately 80 lb/ft³; and • Recovery rates by seam ranging from 67% to 100%. Modifying factors including dilution parameters and technical information related to the mining process are described in detail under Section 13.0 Mining Methods. Economic factors to support the Mineral Reserve estimates are described in Section 18.0 Capital and Operating Costs and 19.0 Economic Analyses. The Mineral Resources as of December 31, 2025 presented in Table 2.2 below have been estimated by applying a series of geologic and physical limits as well as high-level mining and economic constraints. The mining and economic constraints were limited to a level sufficient to support reasonable prospect for future economic extraction of the estimated Mineral Resources. The categorized Mineral Resources reported herein are exclusive of Mineral Reserves.

Net difference of reported Mineral Resources and Mineral Reserves from previous reporting period to current reporting period. The Mineral Resources and Mineral Reserves as of December 31, 2025 reflect modifications from mining extraction of Mineral Reserves. No updates to Mineral Resources were made for 2025. Additionally, MLMC delivered 2.7 million tons during 2025. 30
2.2 Material Properties with no Mineral Resources or Mineral Reserves The lignite coal tonnages at Coteau, Falkirk and Coyote Creek have not been classified as measured resources, indicated resources, or inferred resources as defined in Items 1300 through 1305 of Regulation S-K, and as a result, do not have any proven or probable reserves under such definition and are therefore classified as an Exploration Stage Property pursuant to Items 1300 through 1305 of Regulation S-K. Coteau, Falkirk and Coyote Creek will continue to be classified as exploration stage properties until such time as proven or probable mineral reserves have been established in accordance with subpart 1300 of Regulation S-K, even though they continue to deliver lignite to their respective customers. At Coteau, Coyote Creek and Falkirk, we are paid a management fee per ton of coal or heating unit (MMBtu) delivered. Each contract specifies the indices and mechanics by which fees change over time, generally in line with broad measures of U.S. inflation. The customers are responsible for funding all mine operating cost, including final mine reclamation, and directly or indirectly providing all of the capital required to build and operate the mine. This contract structure eliminates our exposure to spot coal market price fluctuations. Coteau, Coyote Creek and Falkirk each have only one customer for which they extract and deliver coal. These customers operate coal-fired electric generation power plants adjacent to each mine location (and in the case of Coteau, a synthetic natural gas and chemical/fertilizer production facility). The sales price under the Coteau, Coyote Creek and Falkirk contracts are not market driven. Unlike traditional sales made based on market factors, under the provisions of the long-term mining agreements, the coal sales price at Coteau, Coyote Creek and Falkirk includes (i) all costs incurred to extract, process and deliver coal (i.e. the cost of production) and (ii) the agreed-upon profit per ton of coal or MMBtu unit delivered to the customer. Cost of production includes all the costs actually incurred in the operation of the mine including mining, processing and delivery of coal. Costs included within revenue include all production, transportation and maintenance costs including, without limitation, the following types of costs: ◦ Labor, which include wages and all related payroll taxes, benefits and fringes, including welfare plans; group insurance, vacations and other comparable benefits of employees ◦ Materials and supplies, ◦ Tools, ◦ Machinery and equipment not capitalized or leased, ◦ Costs of acquiring interests in coal reserves and surface lands, ◦ Rental of machinery and equipment, ◦ Power costs, ◦ Reasonable and necessary services by third parties ◦ Insurance including worker’s compensation ◦ Certain taxes, and ◦ Cost of reclamation The contractually-determined coal sales price includes reimbursement of all costs incurred and the agreed-upon profit. The agreed-upon profit adjusts based on changes in the level of established indices (e.g., CPI-U and/or PPI indices). The cost-plus nature of the contracts provide assurance that all costs incurred, including contemporaneous and final reclamation, will be reimbursed by the respective customer and negates any risk of loss which allows the mines to remain cash flow positive through the end of the contract terms. The coal sales price as well as profitability at Coteau, Falkirk and Coyote Creek are not subject to any change based on market factors. Profitability at these mines is affected by two factors: demand for coal (because this impacts units of agreed profit that are charged) and changes in the indices that determine coal sales price (because this adjusts the agreed-upon per unit profit). Under any scenario, Coteau, Coyote Creek and Falkirk will be cash flow positive as a result of the terms of the mining agreements. Extraction of Coteau, Coyote Creek and Falkirk’s lignite tonnages is only economically viable as a result of the long-term mining agreements in place with each mine’s respective customer. The development of the Coteau, Coyote Creek and Falkirk mines was conducted in tandem with the development of the respective mine mouth power plants each serve. The power plants were designed to operate exclusively on the coal provided by the adjacent mines. No other market exists for the lignite at Coteau, Coyote Creek and Falkirk as the cost of transportation makes sales to any entity other than the current mine-mouth operator unprofitable. Coteau, Coyote Creek and Falkirk meet the definition of a VIE. In each case, NACCO is not the primary beneficiary of the VIE as it does not exercise financial control; therefore, NACCO does not consolidate the results of these operations within our financial statements. Instead, these contracts are accounted for as equity method investments. The income before income taxes 31
associated with these VIEs is reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations, and our investment is reported on the line Investments in unconsolidated subsidiaries in the Consolidated Balance Sheets. Coteau The Freedom Mine, operated by Coteau, generally produces between 11.0 million and 13.0 million tons of lignite coal annually. The mine started delivering coal in 1983. All production from the mine is delivered to Dakota Coal Company, a wholly owned subsidiary of Basin Electric. Dakota Coal Company then sells the coal to the Synfuels Plant, Antelope Valley Station and Leland Olds Station, all of which are operated by affiliates of Basin Electric. The Synfuels Plant is a coal gasification plant that manufactures synthetic natural gas and produces fertilizers, solvents, phenol, carbon dioxide, and other chemical products for sale. In March 2025, the term of the existing lignite sales agreement was extended until 2032. The term may be extended for an additional five year period, or until 2037, at the option of Coteau. The Freedom Mine is located approximately 90 miles northwest of Bismarck, North Dakota (Figure 2.2). The main entrance to the Freedom Mine is accessed by means of a paved road and is located on County Road 15. Coteau holds 354 leases granting the right to extract approximately 33,451 acres of coal interests and the right to utilize approximately 23,085 acres of surface interests. In addition, Coteau owns in fee 33,888 acres of surface interests and 4,237 acres of coal interests. Substantially all of the leases held by Coteau were acquired in the early 1970s and have been replaced with new leases or have lease terms for a period sufficient to meet Coteau’s contractual production requirements. Figure 2.2 – Freedom Mine Location The towns of Beulah, Hazen, and Stanton along with other smaller communities are within a 40-mile radius of the Freedom Mine and provide a vast supply of the employment base. Employees also come from the cities of Bismarck, Minot, and Dickinson, all of which are less than 100 miles away from the mine. The Freedom Mine sources power for mine office facilities and operations from Roughrider Electric Cooperative, and water for the mine office facilities from the Southwest Water Authority. Fuel for equipment is supplied by multiple local vendors. The Freedom Mine has, or is currently constructing, all supporting infrastructure for mining operations. 32
The main entrance to the Freedom Mine is accessed by traveling north of Beulah on Highway 49 for one mile, then north on County Road 21 for two miles, then west on County Road 26 for three miles, and then north on County Road 15 for two miles as shown on Figure 2.2. Location of the Freedom Mine. Travel to the Freedom Mine by air is possible by means of the Bismarck Municipal Airport, Bismarck, ND, which is approximately 90 miles southeast of the mine. From the airport, the mine is accessed by means of ground transportation by traveling west approximately 50 miles via Interstate 94, taking exit 110 and traveling north approximately 28 miles on ND Highway 49 to Beulah, ND, and so on as explained in the previous paragraph. Travel to the Freedom Mine by rail is possible using the Amtrak Network, which runs through northern North Dakota mostly along the US Highway 2 corridor, and passes through the larger cities of Williston, Minot, Grand Forks, and Fargo, and smaller cities of Stanley, Rugby, and Devils Lake. From these locations, the mine can be accessed via ground transportation on Interstate 29 or Interstate 94 and various highways. The main highways are US Highway 2, US Highway 83, US Highway 85, US Highway 200, and US Highway 281. North Dakota’s freight rail service is largely provided by Burlington Northern Santa Fe Railway and Canadian Pacific Railway. The coal tonnages are located in Mercer County, North Dakota, starting approximately two miles north of Beulah, North Dakota. The formations of sedimentary origin were deposited in the Williston Basin, the dominant structural feature of western North Dakota. The center of the basin is located near the city of Williston, North Dakota, approximately 100 miles northwest of the Freedom Mine. The economically mineable coal occurs in the Sentinel Butte Formation, and is overlain by the Coleharbor Formation. The Coleharbor Formation unconformably overlies the Sentinel Butte Formation. It includes all of the unconsolidated sediments resulting from deposition during glacial and interglacial periods. Lithologic types include gravel, sand, silt, clay and till. The modified glacial channels are in-filled with gravels, sands, silts and clays overlain by till. The coarser gravel and sand beds are generally limited to near the bottom of the channel fill. The general stratigraphic sequence in the upland portions of the reserve area consists of till, silty sands and clayey silts. Fill-in drilling programs are routinely conducted by Coteau for the purpose of refining guidance related to ongoing operations. It is common practice at the Freedom Mine to tighten the drilling density within the three to four-year block ahead of active operations to an average drill hole spacing of 660-feet. However, additional exploration may also be scheduled in areas farther out to increase confidence in future mine plan projections. Coteau utilizes standard surface mining techniques to extract coal from the proposed permit area. Mining operations will typically occur in a sequence of seven events: suitable plant growth material removal, overburden removal, coal removal, overburden replacement, final grading, suitable plant growth material replacement and revegetation. The mine office facilities and original equipment fleets at the Freedom Mine were constructed, acquired, or purchased new during the development stage of the mine. The facilities and equipment are maintained to allow for safe and efficient operation. The equipment is well maintained, in good physical condition and is either updated or replaced periodically with newer models or upgrades available to keep up with modern technology. As equipment wears out, Coteau evaluates what replacement option will be the most cost-efficient, including the evaluation of both new and used equipment. The total cost of the property, plant and equipment, net of applicable accumulated amortization, depreciation and impairment as of December 31, 2025 is $195.5 million. The Freedom Mine currently has no significant encumbrances to the property. No NOVs have been issued at the Freedom Mine in the past three years. Coteau currently has all permits in place for the Freedom Mine to operate through 2031. Permit expansions required to extend the life of the mine through 2042 will be acquired as needed. No mineral processing occurs at the Freedom Mine. Falkirk Mine The Falkirk Mine generally produces between 7 million and 8 million tons of lignite coal annually. The mine started delivering coal in 1978 primarily for the Coal Creek Station, an electric power generating station. Coal Creek Station was owned by GRE until May 1, 2022 when it was purchased by Rainbow Energy. The initial production period is expected to run through May 1, 2032, but the coal sales agreement may be extended or terminated early under certain circumstances. In 2014, Falkirk began delivering coal to Spiritwood Station, another electric power generating station owned by GRE. 33
The Falkirk Mine, operated by Falkirk, is located approximately 50 miles north of Bismarck, North Dakota on a paved access road off U.S. Highway 83 (Figure 2.3). Falkirk holds 341 leases granting the right to extract approximately 43,600 acres of coal interests and the right to utilize approximately 22,475 acres of surface interests. In addition, Falkirk owns in fee 40,722 acres of surface interests and 2,148 acres of coal interests. Substantially all of the leases held by Falkirk were acquired in the early 1970s with initial terms that have been further extended by the continuation of mining operations. The towns of Underwood and Washburn are located within ten miles of the mine, with other small communities also nearby. Numerous employees also reside in Bismarck and Mandan, a distance of about 50 miles. The Falkirk Mine receives both power and water from Coal Creek Station. However, Falkirk’s East shift change building receives water from McLean-Sheridan Rural Water. Fuel for equipment is supplied by multiple local vendors including: Farstad Oil, Missouri Valley Petroleum, and Enerbase Cooperative Resources. The main entrance to the Falkirk Mine is accessed by traveling north from Bismarck on State Highway 83 for approximately 50 miles, then going west on the access road, 1st Street SW located four miles south of Underwood. The mine office is located two miles to the west. Travel to the Falkirk Mine by air is possible using the Bismarck Airport in Bismarck, ND, approximately 55 miles south of the mine, and then using ground transportation, traveling via US Highway 83. The main railway systems near the Falkirk Mine are Canadian Pacific, BNSF, and Dakota Missouri Valley & Western (DMVW). DMVW crosses through the Falkirk Mine Reserve. The coal tonnages are located in McLean County, North Dakota, from approximately nine miles northwest of the town of Washburn, North Dakota to four miles north of the town of Underwood, North Dakota. Structurally, the area is located on an intercratonic basin containing a thick sequence of sedimentary rocks. The economically mineable coal occurs in the Sentinel Butte Formation and the Bullion Creek Formation and are unconformably overlain by the Coleharbor Formation. The Sentinel Butte Formation conformably overlies the Bullion Creek Formation. The general stratigraphic sequence in the upland portions of the reserve area (Sentinel Butte Formation) consists of till, silty sands and clayey silts, main hagel lignite bed, silty clay, lower lignite of the hagel lignite interval and silty clays. Beneath the Tavis Creek, there is a repeating sequence of silty to sand clays with generally thin lignite beds. Operationally, overburden and interburden removal are accomplished using scrapers, dozers, front end loaders, truck shovel fleets, and draglines. Lignite is mined with front end loaders or hydraulic backhoes, and loaded into haul trucks to transport to the stockpile or directly to the customer via truck dumps and conveyors. Fill-in drilling programs are routinely conducted by Falkirk for the purpose of refining guidance related to ongoing operations. It is common practice at the Falkirk Mine to tighten the drilling density within the three to four-year block ahead of active operations to an average drill hole spacing of 1320-feet. However, additional exploration may also be scheduled in areas farther out to increase confidence in future mine plan projections. The mine office facilities and original equipment fleets at the Falkirk Mine were constructed, acquired, or purchased new during the development stage of the mine. The facilities and equipment are maintained to allow for safe and efficient operation. The equipment is well maintained, in good physical condition and is either updated or replaced periodically with newer models or upgrades available to keep up with modern technology. As equipment wears out, Falkirk evaluates what replacement option will be the most cost-efficient, including the evaluation of both new and used equipment. The total cost of the property, plant and equipment, net of applicable accumulated amortization, depreciation and impairment as of December 31, 2025 is $70.7 million. The Falkirk Mine currently has no significant encumbrances to the property. No Notice of Violations (NOVs) have been issued at the Falkirk Mine in the past three years. There are no outstanding permits related to the LOM plan awaiting regulatory approval. The Falkirk Mining Company currently has all permits in place to operate and adhere to the current mine plan. No mineral processing occurs at the Falkirk Mine. 34
Figure 2.3 – Falkirk Mine Location Coyote Creek The Coyote Creek Mine generally produces between 1.5 million and 2.0 million tons of lignite annually. The mine began delivering coal in 2016 to the Coyote Station owned by Otter Tail Power Company, Northern Municipal Power Agency, Montana-Dakota Utilities Company and Northwestern Corporation. The term of the existing lignite sales agreement terminates in 2040. The Coyote Creek Mine is located approximately 70 miles northwest of Bismarck, North Dakota (Figure 2.4). The main entrance to the Coyote Creek Mine is accessed by means of a four-mile paved road extending west off of State Highway 49. Coyote Creek holds a sublease to 86 leases granting the right to mine approximately 8,129 acres of coal interests and the right to utilize approximately 15,168 acres of surface interests. In addition, Coyote Creek Mine owns in fee 160 acres of surface interests and has four easements to conduct coal mining operations on approximately 352 acres. 35
Figure 2.4 – Coyote Creek Mine Location The towns of Beulah, Hazen, and Stanton along with other smaller communities are within a 40-mile radius of the Coyote Creek Mine and provide a vast supply and employment base. A vast supply and employment base also come from some of the major cities of Bismarck, Minot, and Dickinson, all of which are less than 100 miles away from the mine. The Coyote Creek Mine sources power for mine office facilities and operations from Roughrider Electric Cooperative and Montana-Dakota Utilities Co., and water for the mine office facilities from the Southwest Water Authority. Fuel for equipment is supplied by multiple local vendors. The Coyote Creek Mine has all supporting infrastructure for mining operations.

Coyote currently has all permits in place for the Coyote Creek Mine to operate and adhere to a mine plan projected through 2040. No mineral processing occurs at the Coyote Creek Mine. 3.0 Internal Control Disclosure Over Mineral Resources and Reserves The modeling and analysis of our resources and reserves has been developed by our mine personnel and reviewed by several levels of internal management, including the QPs. The development of such resources and reserves estimates, including related assumptions, was a collaborative effort between the QPs and Company staff. This section summarizes the internal control considerations for our development of estimations, including assumptions, used in resource and reserve analysis and modeling. When determining resources and reserves, as well as the differences between resources and reserves, management developed specific criteria, each of which must be met to qualify as a resource or reserve, respectively. These criteria, such as demonstration of economic viability, points of reference and grade, are specific and attainable. The QPs and our management team agree on the reasonableness of the criteria for the purposes of estimating resources and reserves. Calculations using these criteria are reviewed and validated by the QPs. Estimations and assumptions were developed independently for each significant mineral location. All estimates require a combination of historical data and key assumptions and parameters. When possible, resources and data from generally accepted industry sources were used to develop these estimations. Review teams were created by utilizing subject matter experts from across all of NACCO to review the cost assumptions and estimations used as the basis of the classification of mineral resources and reserves. Geological modeling and mine planning efforts serve as a base assumption for resource estimates at MLMC. These outputs have been prepared and reviewed by Company personnel. Mine planning decisions are determined and agreed upon by our management. Management adjusts forward-looking models by reference to historic mining results, including by reviewing actual versus predicted levels of production from the mineral deposit, and if necessary, re-evaluating mining methodologies if production outcomes were not realized as predicted. Ongoing mining of the mineral deposit, coupled with product quality validation pursuant to our and our customer expectations, provides further empirical evidence as to the homogeneity, continuity and characteristics of the deposit. Geologic modeling assumptions are evaluated to historic mining results and are adjusted if necessary to better reflect actual mining results. Ongoing quality validation of production also provides a means to monitor for 37
any potential changes in quality. Also, ongoing monitoring of ground conditions within the mine, surveying for evidence of subsidence and other visible signs of deterioration that may signal the need to re-evaluate rock mechanics and structure of the mine ultimately inform extraction ratios and mine design, which underpin mineral reserve estimates. Management also assesses risks inherent in mineral resource and reserve estimates, such as the accuracy of geophysical data that is used to support mine planning, changes in QPs, identifying hazards and informing operations of the presence of mineable deposits. Also, management is aware of risks associated with potential gaps in assessing the completeness of mineral extraction licenses, entitlements or rights, or changes in laws or regulations that could directly impact the ability to assess mineral resources and reserves or impact production levels. Risks inherent in overestimated reserves can impact financial performance when revealed, such as changes in amortizations that are based on life of mine estimates. 4.0 Customer-owned Properties South Hallsville No. 1 Mine — The Sabine Mining Company The Sabine Mining Company (Sabine) operated the Sabine Mine in Texas. All production from Sabine was delivered to Southwestern Electric Power Company's (SWEPCO) Henry W. Pirkey Plant (the Pirkey Plant). SWEPCO is an American Electric Power (AEP) company. As a result of the early retirement of the Pirkey Plant, Sabine ceased deliveries and commenced final reclamation on April 1, 2023. Funding for mine reclamation is the responsibility of SWEPCO, and Sabine receives compensation for providing mine reclamation services. Sabine will provide mine reclamation services through September 30, 2026. As of October 1, 2026, SWEPCO is obligated to acquire all of the capital stock of Sabine and complete the remaining mine reclamation. 5.0 Facilities and Equipment The facilities and equipment for each of the coal mines are maintained to allow for safe and efficient operation. The equipment is well maintained, in good physical condition and is either updated or replaced periodically with newer models or upgrades available to keep up with modern technology. As equipment wears out, the mines evaluate what replacement option will be the most cost-efficient, including the evaluation of both new and used equipment, and proceed with that replacement. The mining method and total cost of the property, plant and equipment, net of applicable accumulated amortization, depreciation and impairment as of December 31, 2025 is set forth in the chart below: Location Mining Method Total Historical Cost of Mine Property, Plant and Equipment, Net of Applicable Accumulated Amortization, Depreciation and Impairment Unconsolidated Mining Operations (in millions) Freedom Mine — The Coteau Properties Company Dragline operation with 3 draglines $ 195.5 Falkirk Mine — The Falkirk Mining Company Dragline operation with 3 draglines $ 70.7 Coyote Creek Mine — Coyote Creek Mining Company, LLC Dragline operation with 1 dragline $ 97.0 Consolidated Mining Operations Red Hills Mine — Mississippi Lignite Mining Company Dragline operation with 1 dragline $ 54.4 Contract Mining Segment - Operations Contract Mining provides contract mining services for independently owned mines and quarries, primarily operating and maintaining draglines at limestone quarries and utilizing other mining equipment at sand and gravel quarries.

We do not have information that would be available to a company with oil and natural gas operations because detailed information is not generally available to owners of royalty and mineral interests. Consequently, the exact number of wells producing from or drilling on our mineral interests at a given point in time is not determinable. The following table sets forth our estimate of the number of gross and net productive wells: December 31, 2025 December 31, 2024 Gross Net Gross Net Oil 1,663 4.7 1,295 4.3 Natural Gas 851 19.2 922 18.5 Total 2,514 23.9 2,217 22.8 Gross wells are the total wells in which an interest is owned. Net wells are calculated based on our net royalty interest, factoring in both ownership percentage of gross wells and royalty rate. The majority of our producing mineral and royalty interest acreage now, or in the future, can be pooled with third-party acreage to form pooled units. Pooling proportionately reduces our royalty interest in wells drilled in a pooled unit, and it proportionately increases the number of wells in which we have such reduced royalty interest.

Barrel of Oil Equivalent, a conversion factor of 6 MCF of gas was used for 1 equivalent bbl of oil. (4) As an owner of mineral and royalty interests, our access to information concerning activity and operations of our royalty and mineral interests is limited. As a result, we estimated the last two months of 2025 and 2024 production and pricing data using projections based on decline rates of wells and prior expense information. Evaluation and Review of Reserves The reserve estimates as of December 31, 2025 were prepared by Haas & Cobb Petroleum Consultants (Haas & Cobb). Haas & Cobb is an independent, third-party, petroleum engineering firm that meets industry-standards for qualifications, independence, objectivity and confidentiality. The primary technical person, Franklin Stagg, responsible for preparing the Reserve Report, Licensed Professional Engineer in the State of Texas, has been practicing consulting petroleum engineering at Haas & Cobb since 2016 and has over 10 years of industry experience. Haas & Cobb does not own an interest in NACCO or any of our properties, nor is it employed on a contingent basis. A copy of Haas & Cobb's estimated proved reserve report as of December 31, 2025 is incorporated by reference herein to Exhibit 99.1 to this Form 10-K. The properties evaluated for proved reserves are located in Alabama, Louisiana, New Mexico, Ohio, Pennsylvania, Texas, Utah and Wyoming and represent all of our oil and gas reserves. A reserves audit is not the same as a financial audit. Reserve engineering is a subjective process of estimating volumes of economically recoverable oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserve estimate is a function of the quality of available data and of 41
engineering and geological interpretation. As a result, the estimates of different engineers often vary. In addition, the results of drilling, testing, and production may justify revisions of such estimates. Accordingly, reserve estimates often differ from the quantities of oil and natural gas that are ultimately recovered. Estimates of economically recoverable oil and natural gas and of future net revenues are based on several variables and assumptions, all of which may vary from actual results, including geologic interpretation, prices, and future production rates and costs. The reserves estimates have been prepared using standard engineering practices generally accepted by the petroleum industry. Decline curve analysis was used to estimate the remaining reserves of pressure depletion reservoirs with enough historical production data to establish decline trends. Reservoirs under non-pressure depletion drive mechanisms and non-producing reserves were estimated by volumetric analysis, research of analogous reservoirs, or a combination of both. Reserves have been estimated using deterministic and probabilistic methods. The appropriate methodology was used, as deemed necessary, to estimate reserves in conformance with SEC regulations. The maximum remaining reserves life assigned to wells included in this report is 50 years. Total net proved reserves are defined as our natural gas and hydrocarbon liquid reserves after deducting all royalties, overriding royalties, and reversionary interests owned by outside parties that become effective upon payout of specified monetary balances. All reserves estimates have been prepared using standard engineering practices generally accepted by the petroleum industry and conform to guidelines developed and adopted by the SEC. Technologies Used in Reserve Estimation The SEC’s reserves rules allow the use of techniques that have been proved effective by actual production from projects in the same reservoir or an analogous reservoir or by other evidence using reliable technology that establishes reasonable certainty. The term reasonable certainty implies a high degree of confidence that the quantities of oil, natural gas and/or NGLs actually recovered will equal or exceed the estimate. To achieve reasonable certainty, we employed technologies that have been demonstrated to yield results with consistency and repeatability. The technologies and economic data used in the estimation of our proved reserves include, but are not limited to, well logs, geologic maps, seismic data, well test data, production data, historical price and cost information and property ownership interests. The accuracy of the estimates of our reserves is a function of: • the quality and quantity of available data and the engineering and geological interpretation of that data; • estimates regarding the amount and timing of future operating costs, development costs and workovers, all of which may vary considerably from actual results; • future prices of oil, natural gas and NGLs, which may vary considerably from those estimated; and • the judgment of the persons preparing the estimates. The following table presents our estimated net proved oil and natural gas reserves based on the reserve report prepared by Haas & Cobb, our independent petroleum engineering firm. All of our reserves are located in the United States.

One stock tank barrel, or 42 U.S. gallons liquid volume. (2) Mcf. One thousand cubic feet of natural gas at the contractual pressure and temperature bases. We do not currently have any material investments under which it would be required to bear the cost of exploration, production or development. We did not make capital expenditures to convert proved undeveloped reserves from undeveloped to developed. Internal Control Disclosure Our internal staff works closely with Haas & Cobb to ensure the integrity, accuracy and timeliness of the data used to calculate proved reserves relating to NACCO's assets. Internal technical team members met with independent reserve engineers periodically during the period covered by the reserves report to discuss the assumptions and methods used in the proved reserve estimation process. 42
The preparation of our proved reserve estimates is completed in accordance with internal control procedures. These procedures, which are intended to ensure reliability of reserve estimations, include the following: • Review and verification of historical production data, which data is based on actual production as reported by third- party producers who lease our royalty and mineral interests; • Preparation of reserve estimates by Haas & Cobb under the direct supervision of internal staff; and • Verification of property ownership by our land department. The Minerals and Royalties Segment’s Vice President of Engineering and Finance is the technical person primarily responsible for overseeing the preparation of the internal reserve estimates and for coordinating with Haas & Cobb in the preparation of the third-party reserve report. The Vice President of Engineering and Finance has over 15 years of industry experience with positions of increasing responsibility and reports directly to the President of Catapult Mineral Partners, our business unit focused on managing and expanding our portfolio of oil and gas mineral and royalty interests. Estimated Proved Reserves The following table summarizes changes in proved reserves during the year ended December 31, 2025: Estimated Proved Reserves Oil (bbl) (1) NGL (bbl) (1) Residue gas (Mcf) (2) December 31, 2024 695,190 473,930 27,627,670 Purchases 31,899 29,325 117,191 Extensions and discoveries 140,256 46,110 3,679,131 Revisions of previous estimates (3) (217,574) 21,880 (5,460,266) Production (32,077) (15,687) (1,843,911) Other 55,999 29,246 3,387,813 December 31, 2025 673,693 584,804 27,507,628 Estimated Proved Undeveloped Reserves (PUDs) The following table summarizes changes in PUDs during the year ended December 31, 2025: Estimated Proved Undeveloped Reserves Oil (bbl) (1) NGL (bbl) (1) Residue gas (Mcf) (2) December 31, 2024 74,400 30,280 135,830 Extensions and discoveries 54,481 7,547 172,125 Revisions of previous estimates (3) (45,322) (20,299) (55,991) December 31, 2025 83,559 17,528 251,964 (1) Bbl.

(3) Revisions of previous estimates include technical revisions due to changes in commodity prices, historical and projected performance and other factors. As an owner of mineral and royalty interests, we generally do not have evidence or approval of operators’ development plans. As a result, proved undeveloped reserve estimates are limited to those relatively few locations for which drilling permits have been publicly filed. As of December 31, 2025, PUD reserves consists of 126 wells in various stages of drilling or completions. As of December 31, 2025, approximately 2% of our total proved reserves were classified as PUDs. Headquarter locations NACCO leases office space in Highland Hills, Ohio, a suburb of Cleveland, Ohio, which serves as our corporate headquarters. Utility Coal Mining and Minerals and Royalties lease corporate headquarters office space in Plano, Texas. Contract Mining leases office and warehouse space in Medley, Florida. 43

OVERVIEW Management's Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are based upon management's current expectations and are subject to various uncertainties and changes in circumstances. Important factors that could cause actual results to differ materially from those described in these forward-looking statements are set forth below under the heading Forward-Looking Statements. Management's Discussion and Analysis of Financial Condition and Results of Operations include NACCO Industries, Inc.® (NACCO) and its wholly owned subsidiary, NACCO Natural Resources Corporation® (NACCO Natural Resources, and with NACCO collectively, the Company, we, our or us). NACCO Natural Resources brings natural resources to life by delivering aggregates, minerals, reliable fuels and environmental solutions through our robust portfolio of businesses. We operate under three reportable business segments: Utility Coal Mining, Contract Mining and Minerals and Royalties. The Utility Coal Mining segment, operated by North American Coal®, manages surface coal mines that are exclusive, long-term fuel providers for power generation companies. The Contract Mining segment, operated by North American Mining®, is a leading provider of a broad range of specialized, long-term contract mining services. The Minerals and Royalties segment, which includes the Catapult Mineral Partners® (Catapult) business, acquires and promotes the development of mineral and royalty interests and other related investments. In addition to the reportable segments discussed above, we also operate other businesses that are not currently reported as separate segments. These businesses complement our existing operations and support our long-term growth strategic objectives. Mitigation Resources of North America® (Mitigation Resources) provides natural resource restoration and reclamation services that include stream and wetland mitigation solutions. ReGen Resources is pursuing opportunities to develop new power generation resources. We also have items not directly attributable to an operating segment. These items primarily include administrative costs related to public company reporting requirements, including management and board compensation, the financial results of developing businesses and Bellaire Corporation (Bellaire). Bellaire manages long-term liabilities related to former Eastern U.S. underground mining activities. All financial statement line items below operating profit (other expense, including interest expense and interest income, the benefit for income taxes and net income) are presented and discussed within this Form 10-K on a consolidated basis. See Item 1. Business beginning on page 1 in this Form 10-K for further discussion of NACCO's subsidiaries. Additional information relating to financial and operating data on a segment basis (including unallocated items) is set forth in Note 15 to the Consolidated Financial Statements contained in this Form 10-K. CRITICAL ACCOUNTING POLICIES AND ESTIMATES Our discussion and analysis of our financial condition and results of operations are based upon the consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities (if any). On an ongoing basis, we evaluate our estimates based on historical experience, actuarial valuations and various other assumptions that are believed to be reasonable under the 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. Actual results may differ from those estimates. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of the consolidated financial statements. Revenue recognition: Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. We account for revenue in accordance with Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers. See Note 3 to the Consolidated Financial Statements in this Form 10-K for further discussion of our revenue recognition. Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share and Percentage Data) 46
Long-lived assets: We periodically evaluate long-lived assets for impairment when changes in circumstances or the occurrence of certain events indicate the carrying amount of an asset or asset group may not be recoverable. Upon identification of indicators of impairment, we evaluate the carrying value of the asset by comparing the estimated future undiscounted cash flows generated from the use of the asset or asset group and its eventual disposition with the asset's net carrying value. If the carrying value of an asset is considered impaired, an impairment charge is recorded for the amount that the carrying value of the long-lived asset or asset group exceeds its fair value. Fair value is estimated as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Income taxes: We file income tax returns in the U.S. federal jurisdiction, and in various state and foreign jurisdictions. Tax law requires certain items to be included in the tax return at different times than the items are reflected in the financial statements. Some of these differences are permanent, such as the benefit associated with percentage depletion (tax deductions for depletion that may exceed the tax basis in the mineral reserve) and expenses that are not deductible for tax purposes, and some differences are temporary, reversing over time, such as depreciation expense. These temporary differences create deferred tax assets and liabilities using currently enacted tax rates. The objective of accounting for income taxes is to recognize the amount of taxes payable or refundable for the current year, and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the financial statements or tax returns. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the provision for income taxes in the period that includes the enactment date. Management is required to estimate the timing of the recognition of deferred tax assets and liabilities, make assumptions about the future deductibility of deferred tax assets and assess deferred tax liabilities based on enacted laws and tax rates for the appropriate tax jurisdictions to determine the amount of such deferred tax assets and liabilities. Changes in the calculated deferred tax assets and liabilities may occur in certain circumstances, including statutory income tax rate changes, statutory tax law changes, or changes in the structure or tax status. Our tax assets, liabilities, and tax expense are supported by historical earnings and losses and our best estimates and assumptions of future earnings. We assess whether a valuation allowance should be established against our deferred tax assets based on consideration of all available evidence, both positive and negative, using a more likely than not standard. This assessment considers, among other matters, scheduled reversals of deferred tax liabilities, projected future taxable income, tax- planning strategies, and results of recent operations. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates we use to manage the underlying businesses. When we determine, based on all available evidence, that it is more likely than not that deferred tax assets will not be realized, a valuation allowance is established. Since significant judgment is required to assess the future tax consequences of events that have been recognized in our financial statements or tax returns, the ultimate resolution of these events could result in adjustments to our financial statements and such adjustments could be material. We believe the current assumptions, judgments and other considerations used to estimate the current year accrued and deferred tax positions are appropriate. If the actual outcome of future tax consequences differs from these estimates and assumptions, due to changes or future events, the resulting change to the provision for income taxes could have a material impact on our results of operations and financial position. Since 2021, we have participated in a voluntary program with the IRS called Compliance Assurance Process (CAP). The objective of CAP is to contemporaneously work with the IRS to achieve federal tax compliance and resolve all or most issues prior to the filing of the tax return. See Note 13 to the Consolidated Financial Statements in this Form 10-K for further discussion of our income taxes. Item 7.

CONSOLIDATED FINANCIAL SUMMARY Our results of operations were as follows for the years ended December 31: 2025 2024 Revenues: Utility Coal Mining $ 88,188 $ 68,611 Contract Mining 140,013 119,600 Minerals and Royalties 37,630 34,579 Unallocated Items 15,080 17,707 Eliminations (3,713) (2,789) Total revenue $ 277,198 $ 237,708 Operating profit (loss): Utility Coal Mining $ 17,155 $ 24,311 Contract Mining 5,767 5,772 Minerals and Royalties 29,108 28,927 Unallocated Items (29,962) (23,317) Eliminations (87) 12 Total operating profit $ 21,981 $ 35,705 Interest expense 5,754 5,566 Interest income (3,052) (4,428) Closed mine obligations 457 2,381 Loss (gain) on equity securities 726 (1,805) Gain on settlement of excess funding liability (3,590) — Pension settlement charge 7,804 — Other, net 738 345 Other expense, net 8,837 2,059 Income before income tax benefit 13,144 33,646 Income tax benefit (4,430) (95) Net income $ 17,574 $ 33,741 Effective income tax rate (33.7) % (0.3) % The components of the change in revenues and operating profit are discussed below in Segment Results. Other expense, net Interest expense increased modestly in 2025 compared with 2024 due to higher average borrowings, partially offset by an increase in capitalized interest and lower average interest rates. Interest income decreased in 2025 compared with 2024 due to lower earnings on reduced cash balances. Loss (gain) on equity securities represents changes in the market price of invested assets reported at fair value. The change during 2025 compared with 2024 was due to fluctuations in the market prices of the exchange-traded equity securities. See Note 9 to the Consolidated Financial Statements in this Form 10-K for further discussion of our invested assets reported at fair value. Closed mine obligations decreased in 2025 compared with 2024 due to a change in the estimate of future water treatment costs at Bellaire. See Note 7 to the Consolidated Financial Statements in this Form 10-K for further discussion of our asset retirement obligations. Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share and Percentage Data) 48
During 2025, we terminated the NACCO Combined Defined Benefit Plan (Combined Plan) and settled all future obligations by transferring the remaining benefit obligations to a third-party insurance company. Although the plan was over funded, we recognized a $7.8 million non-cash Pension settlement charge. See Note 1 and Note 14 to the Consolidated Financial Statements in this Form 10-K for further information on the Combined Plan. During 2025, $14.5 million of excess funds from the terminated Falkirk Defined Benefit Plan were directly transferred to the NACCO 401(k) plan. The NACCO 401(k) plan is a qualified replacement plan; therefore, these funds will be utilized to offset future profit sharing contributions to eligible 401(k) plan participants. During 2025, NACCO and Falkirk’s former customer agreed to settle the corresponding liability for $10.9 million, resulting in a $3.6 million Gain on settlement of excess funding liability. See Note 1 to the Consolidated Financial Statements in this Form 10-K for further information on the excess funds. Income Taxes We recorded an income tax benefit of $4.4 million for the year ended December 31, 2025 on income before income tax of $13.1 million, or (33.7)%, compared to an income tax benefit of $0.1 million on income before income tax of $33.6 million, or (0.3)%, for the year ended December 31, 2024. The years ended December 31, 2025 and 2024 included $1.9 million and $4.0 million of discrete tax benefits, primarily for deferred tax adjustments and the reversal of uncertain tax provisions, respectively. Excluding the respective $1.9 million and $4.0 million of discrete tax benefits, the effective income tax rate was (19.5)% and 11.5% in 2025 and 2024, respectively. The change in the effective income tax rate for 2025 compared to 2024, excluding the impact of discrete items, is primarily due to an increase in losses at entities that do not benefit from percentage depletion. Losses generated by these entities generate tax deductions at the statutory rate. This shift in the mix of pre-tax income resulted in a benefit tax rate in 2025. In addition, the benefit from percentage depletion is not directly related to the amount of pre-tax income recorded in a period. Accordingly, in periods where income or loss before income tax is relatively small, the proportional effect of the benefit from percentage depletion on the effective tax rate may be significant. When income tax expense is recorded, the benefit from percentage depletion decreases the effective income tax rate, while the effect is to increase the effective income tax rate when a benefit for income taxes is recorded. See Note 13 to the Consolidated Financial Statements in this Form 10-K for further discussion of our income taxes. Item 7.

LIQUIDITY AND CAPITAL RESOURCES Cash Flows The following tables detail the change in cash flow for the years ended December 31: 2025 2024 Change Operating activities: Net income $ 17,574 $ 33,741 $ (16,167) Depreciation, depletion and amortization 25,277 24,652 625 Deferred income taxes 58 1,517 (1,459) Stock-based compensation 8,280 5,832 2,448 Gain on sale of assets (286) (5,146) 4,860 Inventory impairment charges 6,986 9,643 (2,657) Pension settlement charge 7,804 — 7,804 Other 8,006 (3,352) 11,358 Changes in operating assets and liabilities (22,790) (44,598) 21,808 Net cash provided by operating activities 50,909 22,289 28,620 Investing activities: Expenditures for property, plant and equipment and acquisition of mineral interests (53,286) (55,419) 2,133 Proceeds from the sale of assets 2,799 822 1,977 Equity method investment (16,702) (16,556) (146) Return of equity method investment 3,295 — 3,295 Other (282) (139) (143) Net cash used for investing activities (64,176) (71,292) 7,116 Cash flow before financing activities $ (13,267) $ (49,003) $ 35,736 The $28.6 million favorable change in net cash provided by operating activities during 2025 compared with 2024 was primarily due to changes in operating assets and liabilities. Inventory levels at December 31, 2025 and December 31,2024 were relatively consistent, whereas inventories increased during 2024. Accounts receivable decreased during 2025 due to the timing of collections, whereas accounts receivable increased during 2024. These favorable items were partially offset by an unfavorable change in accrued expenses, mainly attributable to a decrease in accrued payroll during the 2025 period, whereas accrued payroll increased during 2024. 2025 2024 Change Financing activities: Net additions to long-term debt and revolving credit agreements $ 11 $ 55,710 $ (55,699) Debt issuance costs — (2,415) $ 2,415 Cash dividends paid (7,335) (6,624) (711) Purchase of treasury shares (2,534) (9,944) 7,410 Net cash (used for) provided by financing activities $ (9,858) $ 36,727 $ (46,585) The change in net cash (used for) provided by financing activities was primarily due to relatively consistent debt borrowings during 2025 compared with additions during 2024. This change was partially offset by decreases in share repurchases and debt Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share and Percentage Data) 50
issuance costs during 2025. See Note 12 to the Consolidated Financial Statements in this Form 10-K for a discussion of our stock repurchase programs. Financing Activities In September 2024, NACCO Natural Resources amended its secured revolving line of credit (Facility) to increase the revolving credit commitments to $200.0 million and extend the maturity to September 2028. Borrowings outstanding under the Facility were $75.0 million at December 31, 2025. At December 31, 2025, the excess availability under the Facility was $74.5 million, which reflects a reduction for outstanding letters of credit of $50.5 million. NACCO has not guaranteed any borrowings of NACCO Natural Resources. The Facility allows for the payment to NACCO of dividends and advances under certain circumstances. Dividends (to the extent permitted by the Facility) and management fees are the primary sources of cash for NACCO and enable us to pay dividends to stockholders and repurchase shares. The Facility has performance-based pricing, which sets interest rates based upon NACCO Natural Resources achieving various levels of debt to EBITDA ratios, as defined in the Facility. Borrowings bear interest at a floating rate plus a margin based on the level of debt to EBITDA ratio achieved. The applicable margins, effective December 31, 2025, for base rate and Term Secured Overnight Financing Rate loans were 1.50% and 2.50%, respectively. The Facility has a commitment fee which is based upon achieving various levels of net debt to EBITDA ratios. The commitment fee was 0.40% on the unused commitment at December 31, 2025. During the years ended December 31, 2025 and December 31, 2024, the average borrowing under the Facility was $57.3 million and $27.2 million, respectively, and the weighted-average annual interest rate was 7.21% and 8.83%, respectively. The Facility contains restrictive covenants, which require, among other things, NACCO Natural Resources to maintain a maximum net debt to EBITDA ratio of 2.75 to 1.00 and an interest coverage ratio of not less than 4.00 to 1.00. The Facility provides the ability to make loans, dividends and advances to NACCO, with some restrictions based on maintaining a maximum net debt to EBITDA ratio of 1.50 to 1.00, or if greater than 1.50 to 1.00, a Fixed Charge Coverage Ratio of 1.10 to 1.00. At December 31, 2025, NACCO Natural Resources was in compliance with all financial covenants in the Facility. The obligations under the Facility are guaranteed by certain of NACCO Natural Resources' direct and indirect, existing and future domestic subsidiaries, and is secured by certain assets of NACCO Natural Resources and the guarantors, subject to customary exceptions and limitations. We believe funds available from cash on hand, the Facility and operating cash flows will provide sufficient liquidity to meet our operating needs and commitments arising during the next twelve months and until the expiration of the Facility in September 2028. See Note 8 and Note 10 to the Consolidated Financial Statements in this Form 10-K for further information on our other financing arrangements and leases, respectively. Expenditures for property, plant and equipment and mineral interests Following is a table which summarizes expenditures (in millions): Planned Actual Actual 2026 2025 2024 NACCO $ 89.0 $ 53.3 $ 55.4 Actual expenditures for 2025 were $8.0 million in the Utility Coal Mining Segment, $32.0 million in the Contract Mining segment, $7.7 million in the Minerals and Royalties segment and $5.6 million in growth business included in Unallocated Items. Capital expenditures were primarily for a dragline and dragline related improvements in the Contract Mining segment. Capital expenditures for 2026 are expected to be up to $6 million in the Utility Coal Mining segment, $36 million in the Contract Mining segment, $20 million in the Minerals and Royalties segment and $27 million in growth businesses included in Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share and Percentage Data) 51
Unallocated Items. The majority of these expenditures relate to business development opportunities and will only be made if the projects meet our growth investment criteria. Expenditures are expected to be funded from internally generated funds and/ or bank borrowings. Capital Structure NACCO's consolidated capital structure is presented below: December 31 2025 2024 Change Cash and cash equivalents $ 49,708 $ 72,833 $ (23,125) Other net tangible assets 500,411 451,962 48,449 Intangible assets, net 4,725 5,475 (750) Net assets 554,844 530,270 24,574 Total debt (100,895) (99,514) (1,381) Closed mine obligations (24,706) (25,809) 1,103 Total equity $ 429,243 $ 404,947 $ 24,296 Debt to total capitalization 19 % 20 % (1) % The increase in other net tangible assets was mainly the result of increases in Property, plant and equipment, the Equity method investment in Eiger Resources and the establishment of the Prepaid profit sharing asset during 2025. During 2025, we invested an additional $15.0 million in Eiger Resources, which holds operated and non-operated working interests in oil and natural gas assets in the Kansas and the Oklahoma portion of the Hugoton basin. This resulted in an increase in Equity method investment in Eiger Resources. See Note 1 to the Consolidated Financial Statements in this Form 10-K for further information on Eiger Resources. The excess funds from the terminated Combined Plan as well as the excess funds from the Falkirk Defined Benefit Plan will be utilized by the NACCO 401(k) plan, which is a qualified replacement plan. These funds will be used for future profit sharing contributions to eligible 401(k) plan participants, which resulted in an increase in Prepaid profit sharing. See Note 1 to the Consolidated Financial Statements in this Form 10-K for further information on the excess funds. Contractual Obligations, Contingent Liabilities and Commitments NACCO has asset retirement obligations. See Note 7 to the Consolidated Financial Statements in this Form 10-K for further discussion of our asset retirement obligations. NACCO has unrecognized tax benefits, including interest and penalties. See Note 13 to the Consolidated Financial Statements in this Form 10-K for further discussion of our income taxes. We are a party to certain guarantees related to Coyote Creek. We believe that the likelihood of future performance under the guarantees is remote, and no amounts related to these guarantees have been recorded. See Note 16 to the Consolidated Financial Statements in this Form 10-K for further discussion of our guarantees. We utilize letters of credit to support commitments made in the ordinary course of business. As of December 31, 2025 and 2024, outstanding letters of credit totaled $50.5 million and $30.9 million, respectively. ENVIRONMENTAL MATTERS We are affected by the regulations of numerous agencies, particularly the Federal Office of Surface Mining, the U.S. Environmental Protection Agency, the U.S. Army Corps of Engineers and associated state regulatory authorities. In addition, we closely monitor proposed legislation and regulation concerning SMCRA, CAA, ACE, CWA, RCRA, CERCLA, OBBBA and other regulatory actions. See Item 1 and Item 1A. in Part I of this Form 10-K for further discussion of these matters. Item 7.

SEGMENT RESULTS UTILITY COAL MINING SEGMENT FINANCIAL REVIEW See Item 2. Properties on page 25 in this Form 10-K for discussion of our mineral resources and mineral reserves. Tons of coal delivered by the Utility Coal Mining segment were as follows for the years ended December 31: 2025 2024 Unconsolidated mines 20,400 21,308 Consolidated mines 2,730 1,922 Total tons delivered 23,130 23,230 The results of operations for the Utility Coal Mining segment were as follows for the years ended December 31: 2025 2024 Revenues $ 88,188 $ 68,611 Cost of sales 94,155 79,375 Gross loss (5,967) (10,764) Earnings of unconsolidated operations(a) 54,471 51,821 Business interruption insurance recoveries — 13,612 Selling, general and administrative expenses 30,702 30,112 Amortization of intangible assets 750 531 Gain on sale of assets (103) (285) Operating profit $ 17,155 $ 24,311 (a) See Note 16 to the Consolidated Financial Statements in this Form 10-K for a discussion of our unconsolidated subsidiaries, including summarized financial information. 2025 Compared with 2024 Revenues increased 28.5% in 2025 compared with 2024 primarily due to an increase in customer requirements at MLMC partially offset by a reduction in the contractually determined per ton sales price. A boiler issue at the customer's Red Hills Power Plant reduced customer requirements in 2024. The following table identifies the components of change in Operating profit for 2025 compared with 2024: Operating Profit 2024 $ 24,311 Increase (decrease) from: Business interruption insurance recoveries in 2024 (13,612) Selling, general and administrative expenses (590) Amortization of intangibles (219) Net change on sale of assets (182) Gross loss 4,797 Earnings of unconsolidated operations 2,650 2025 $ 17,155 Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share and Percentage Data) 53
Operating profit decreased by $7.2 million in 2025 compared with 2024 primarily due to the absence of MLMC's business interruption insurance recoveries for the boiler issue at the Red Hills Power Plant. This unfavorable change was partially offset by a decrease in gross loss and an increase in earnings of unconsolidated operations. Gross loss was favorable during 2025 compared with the 2024 period, primarily due to an increase in customer requirements and a reduction in cost per ton delivered. The increase in earnings of unconsolidated operations was primarily due to a higher per ton management fee at Falkirk as temporary price concessions ended in the second quarter of 2024. CONTRACT MINING SEGMENT FINANCIAL REVIEW Aggregate tons delivered by the Contract Mining segment were as follows for the years ended December 31: 2025 2024 Total tons delivered 54,885 54,963 The results of operations for the Contract Mining segment were as follows for the years ended December 31: 2025 2024 Total revenues $ 140,013 $ 119,600 Reimbursable costs 91,116 74,636 Revenues excluding reimbursable costs $ 48,897 $ 44,964 Revenues $ 140,013 $ 119,600 Cost of sales 129,876 110,821 Gross profit 10,137 8,779 Earnings of unconsolidated operations(a) 4,789 5,010 Selling, general and administrative expenses 9,321 8,365 Gain on sale of assets (162) (348) Operating profit $ 5,767 $ 5,772 (a) See Note 16 to the Consolidated Financial Statements in this Form 10-K for a discussion of our unconsolidated subsidiaries, including summarized financial information. 2025 Compared with 2024 Total revenues increased in 2025 compared with 2024, primarily due to an increase in reimbursable costs, which have an offsetting amount in cost of sales and have no impact on gross profit. Revenues excluding reimbursable costs increased 8.7% in 2025 compared with 2024, mainly due to an increase in part sales. The following table identifies the components of change in Operating profit for 2025 compared with 2024. Operating Profit 2024 $ 5,772 Increase (decrease) from: Gross profit 1,358 Selling, general and administrative expenses (956) Net change on sale of assets (186) Earnings of unconsolidated operations (221) 2025 $ 5,767 Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share and Percentage Data) 54
Operating profit was comparable during 2025 and 2024. An increase in gross profit was largely offset by an increase in selling, general and administrative expenses. The improvement in gross profit was mainly the result of an increase in part sales partially offset by a $1.1 million charge to establish a loss contingency in 2025. The increase in selling, general and administrative expenses during 2025 was primarily the result of higher employee-related costs, partially offset by the absence of a $0.9 million prior year charge to establish an allowance against a customer receivable. MINERALS AND ROYALTIES SEGMENT FINANCIAL REVIEW Oil and natural gas prices have been historically volatile and may continue to be volatile in the future. The table below shows the average price as reported by the United States Energy Information Administration for the years ended December 31: 2025 2024 West Texas Intermediate Average Crude Oil Price $ 65.46 $ 76.55 Henry Hub Average Natural Gas Price $ 3.53 $ 2.19 These indicated prices do not necessarily reflect the contract terms for our sales. As an owner of royalty and mineral interests, our access to information concerning activity and operations of our royalty and mineral interests is limited. We do not have information that would be available to a company with working interests in oil and natural gas operations because detailed information is not generally available to owners of royalty and mineral interests. See Item 2. Properties on page 40 in this Form 10-K discussion of our proved reserves. The results of operations for the Minerals and Royalties segment were as follows for the years ended December 31: 2025 2024 Oil and natural gas revenues $ 31,307 $ 27,157 Other revenues 6,323 7,422 Total Revenues $ 37,630 $ 34,579 Total Revenues $ 37,630 $ 34,579 Cost of sales 5,666 5,234 Gross profit 31,964 29,345 Earnings of unconsolidated operations 2,571 647 Selling, general and administrative expenses 5,444 5,577 Gain on sale of assets (17) (4,512) Operating profit $ 29,108 $ 28,927 Revenues increased 8.8% in 2025 compared with 2024 primarily due to an increase in natural gas revenue as a result of higher natural gas prices and increased production, partially offset by a decrease in oil revenue as a result of lower oil prices and decreased production. Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share and Percentage Data) 55
The following table identifies the components of change in Operating profit for 2025 compared with 2024. Operating Profit 2024 $ 28,927 Increase (decrease) from: Gross profit 2,619 Earnings of unconsolidated operations 1,924 Selling, general and administrative expenses 133 Gain on sale of assets (4,495) 2025 $ 29,108 Operating profit increased by $0.2 million in 2025 compared with 2024, primarily due to improvements in gross profit and earnings of unconsolidated operations. The increase in gross profit was mainly due to higher natural gas revenues. The increase in earnings of unconsolidated operations was primarily related to an additional investment in Eiger Resources during the fourth quarter of 2024. These increases were partially offset by the absence of a $4.5 million prior year gain on sale of land. UNALLOCATED ITEMS AND ELIMINATIONS FINANCIAL REVIEW Unallocated Items and Eliminations were as follows for the years ended December 31: 2025 2024 Operating loss $ (30,049) $ (23,305) 2025 Compared with 2024 Operating loss increased during 2025 compared with 2024 primarily due to an increase in selling, general and administrative expenses. This increase was mainly the result of higher employee-related costs and increased costs related to our business development projects. Employee-related costs increased primarily due to elevated medical costs and higher share-based incentive compensation expense as a result of an increase in our share price during 2025. NACCO Industries, Inc. Outlook NACCO Industries is a growing diversified natural resources company with a unique business model strategically positioned to deliver stable and growing financial returns over the long term. Our business model is purposely built for durability and resilience with an expanding portfolio of long-term contracts, relationships and investments that leverage our proven operational expertise, disciplined capital allocation and an entrepreneurial yet patient approach. We have methodically built unique capabilities and clear competitive advantages that allow us to pursue a wide range of growth opportunities, often completely integrated into customers’ operations in partnership-based relationships. We have multiple vectors for value creation, and we are steadfastly committed to delivering compounding returns and expanding investor value over the long term. Our foundation rests on a stable base of long-term coal-mining contracts and legacy mineral and royalty assets, which generate dependable recurring cash flows. As new long-term contracts and investments are added across the Company, these new multi-year agreements create a “layering” effect as their contributions compound. This provides cash flow stability. The momentum our operations experienced in 2025, particularly in the second half, is expected to continue into 2026, with meaningful year-over-year improvements in consolidated operating profit, net income and EBITDA. At our Utility Coal Mining segment, operated by North American Coal, we expect an increase in operating profit compared with 2025. Improvements at MLMC as a result of an increase in the contractually determined per ton sales price are expected Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share and Percentage Data) 56
to be partly offset by lower earnings at the unconsolidated mining operations due to reduced income associated with the wind down of reclamation services at Sabine. While we expect modest year-over-year improvements at MLMC, the customer's power plant began a maintenance outage in mid-February 2026. The power plant is expected to resume operations in mid-March. Any delay or further changes in demand, dispatch and/or reduced mechanical availability at the power plant could decrease current expectations. The Contract Mining segment, operated by North American Mining, serves as our primary mining growth platform. Through continued geographic and mineral expansion, we are building a growing portfolio of long-term contracts that strengthen the foundation for sustained profitability. In October 2025, we secured a multi-year dragline services contract as part of a U.S. Army Corps of Engineers construction project in Palm Beach County, Florida. We also anticipate commencing operations at a new limestone quarry in Arizona in 2026. We expect the segment to deliver a significant year-over-year increase in operating profit and Segment Adjusted EBITDA as a result of higher customer demand, earnings contributions from new contracts and continued momentum from 2025 activities. Sawtooth, a North American Mining subsidiary, provides exclusive comprehensive mining services at Thacker Pass, which is owned by a joint venture led by Lithium Americas Corp. (TSX: LAC; NYSE: LAC). Sawtooth will supply all of the lithium- bearing ore requirements for our customer's Thacker Pass lithium processing facility, which is currently under construction. This project is providing stable income during construction and is expected to contribute increased income and long-term cash flows once lithium production commences, which is targeted for late 2027. The Minerals and Royalties segment, managed by Catapult, has constructed a high-quality, diversified portfolio of oil and gas mineral and royalty interests in the United States. The Catapult team is expanding its portfolio by leveraging a data-driven approach to capital deployment that incorporates a longer-term view of production and development. We believe this provides a competitive advantage in the U.S. market. In July 2025, Catapult completed a $4.2 million acquisition of mineral interests within the Permian Basin. The acquisition includes a mix of producing wells, as well as additional development opportunities with existing operators in the area. This segment also has an investment in a company that holds operated and non-operated working interests in oil and natural gas assets. While these investments are expected to contribute favorably to 2026, commodity price forecasts as well as development and production assumptions are expected to result in an overall year-over-year decrease in Minerals and Royalties' operating profit and Segment Adjusted EBITDA, particularly in the second half of the year. Our forecast was developed prior to recent events in the Middle East. Any changes in commodity prices or production as a result of this conflict could alter current expectations. Mitigation Resources provides natural resource restoration and reclamation services that include stream and wetland mitigation solutions. Mitigation Resources is successfully leveraging its strong reputation and clear competitive strengths to expand into additional mitigation, restoration and reclamation markets. Mitigation Resources is expected to deliver increasing profitability over time from the sale of mitigation credits and as reclamation and restoration services expand. This business, while currently variable in performance due to permit and project timing, is expected to generate a profit in the second half of 2026 and move toward more consistent results over time as the business expands. We continue to invest in our businesses to drive future growth. In 2026, we anticipate total capital expenditures of up to $89 million. The majority of these expenditures relate to business development opportunities and will only be made if the projects meet our growth investment criteria. These anticipated capital investments are expected to result in a use of cash before financing greater than in 2025. Our businesses provide critical inputs for electricity generation, construction and development, and the production of industrial minerals and chemicals. As the need for uninterrupted energy grows, industry fundamentals for natural resources are expected to continue to strengthen, reinforcing the critical need to keep existing, reliable baseload resources online. In 2026, the National Coal Council, an advisory committee to the U.S. Secretary of Energy, was re-established. This council is focused on advising the Department of Energy on reinforcing coal’s strategic role in U.S. energy policy and providing actionable advice on sustaining coal plant operations and prioritizing coal to support grid reliability to support our country’s economic competitiveness and national security. The re-establishment of this council and the underlying improving regulatory Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share and Percentage Data) 57
environment reinforce our confidence in our prospects for 2026, our overall business trajectory and longer-term growth opportunities. Our conservative approach to maintaining a strong capital structure and operating discipline minimizes risk, while the compounding effect of a growing portfolio of long-term contracts and deliberate growth investments create a robust foundation for cash flow growth. With a perspective that spans decades, we are methodically building a strong, stable business that is expected to deliver annuity-like returns. This long-term view allows us to leverage our core skills for strategic, measured expansion and pursue opportunities with longer-term horizons and higher returns. We pursue opportunities that other companies with shorter time horizons might overlook. Our commitment is to generate increasing cash flows and return value to stockholders, whether through reinvestment for growth or direct returns such as share repurchases and payment of dividends. We remain confident in our ability to drive growth, expand our capabilities and reward shareholders over the long run.

Report of Independent Registered Public Accounting Firm To the Stockholders and the Board of Directors of NACCO Industries, Inc. Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of NACCO Industries, Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income, equity and cash flows for each of the two years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(b) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated March 4, 2026 expressed an unqualified opinion thereon. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit review committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Unconsolidated subsidiaries – accounting for variable interest entities Description of the Matter As discussed in Note 1 and 16 to the consolidated financial statements, certain of the operating coal mines and entities within the Contract Mining segment, collectively referred to as the “Unconsolidated Subsidiaries,” are variable interest entities (VIEs) and are accounted for under the equity method. In each case, NACCO is not the primary beneficiary of the VIE as it does not exercise financial control. Although NACCO owns 100% of the equity and manages the daily operations of the Unconsolidated Subsidiaries, the Company has determined that the equity capital provided by NACCO is not sufficient to adequately finance the ongoing activities or absorb any expected losses without additional support from the customers. The customers have a controlling financial interest and have the power to direct activities that most significantly affect the economic performance of the entities. As a result, the Company is not the primary beneficiary and therefore does not consolidate these entities’ financial position or results of operations. The Company regularly evaluates if there are reconsideration events which could change the Company's conclusion as to whether these entities meet the definition of a VIE and the determination of the primary beneficiary. The income before income taxes associated with these VIEs is reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations, and the Company’s investment is reported on the line Investments in unconsolidated subsidiaries in the Consolidated Balance Sheets. Evaluating the Company’s judgments in determining whether an entity is a VIE and the primary beneficiary of the VIE at formation and reconsideration events requires a high degree of complex auditor judgment. The Company also monitors for reconsideration events relating to the Unconsolidated Subsidiaries, which necessitates on-going critical judgments over whether any such events have arisen that require a re-evaluation of prior accounting judgments. How We Addressed the Matter in Our Audit We obtained an understanding, evaluated and tested the design and operating effectiveness of the controls surrounding the Company’s application of the variable interest model and the processes to continually assess the implications of significant transactions and events that could trigger a VIE reconsideration event. For those entities where the Company has determined it is not the primary beneficiary, we evaluated the Company’s accounting for and disclosure of the Unconsolidated Subsidiaries under the equity method in accordance with the generally accepted accounting principles. To test the identification of reconsideration events, we obtained and inspected amendments to the agreements with customers, if any, and evaluated evidence from other parts of the audit to determine if a reconsideration event arose that necessitated a re- evaluation of previous accounting judgments. These procedures included, among others, reading board minutes, inquiring of management about transactions or events that could require a reconsideration of previous consolidation conclusions and obtaining direct confirmation of the total annual support provided in accordance with the contractual arrangements from the customers. /s/ Ernst & Young LLP We have served as the Company’s auditor since 2002.

Report of Independent Registered Public Accounting Firm To the Stockholders and the Board of Directors of NACCO Industries, Inc. Opinion on Internal Control Over Financial Reporting We have audited NACCO Industries, Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, NACCO Industries, Inc. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2025 consolidated financial statements of the Company and our report dated March 4, 2026 expressed an unqualified opinion thereon. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s report on internal control over financial reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young LLP Cleveland, Ohio March 4, 2026 F-5

NOTE 1—Principles of Consolidation and Nature of Operations The accompanying Consolidated Financial Statements include the accounts of NACCO Industries, Inc.® (NACCO) and its wholly owned subsidiary, NACCO Natural Resources Corporation® (NACCO Natural Resources, and with NACCO collectively, the Company, we, our or us). NACCO Natural Resources brings natural resources to life by delivering aggregates, minerals, reliable fuels and environmental solutions through our robust portfolio of businesses. We operate under three business segments: Utility Coal Mining, Contract Mining and Minerals and Royalties. The Utility Coal Mining segment, operated by North American Coal®, manages surface coal mines that are exclusive, long-term fuel providers for power generation companies. The Contract Mining segment, operated by North American Mining®, is a leading provider of a broad range of specialized, long-term contract mining services. The Minerals and Royalties segment, which includes the Catapult Mineral Partners® (Catapult) business, acquires and promotes the development of mineral and royalty interests and other related investments. In addition to the reportable segments discussed above, we also operate other businesses that are not currently reported as separate segments. These businesses complement our existing operations and support our long-term growth strategic objectives. Mitigation Resources of North America® (Mitigation Resources) provides natural resource restoration and reclamation services that include stream and wetland mitigation solutions. ReGen Resources is pursuing opportunities to develop new power generation resources. We also have items not directly attributable to an operating segment. These items primarily include administrative costs related to public company reporting requirements, including management and board compensation, the financial results of developing businesses and Bellaire Corporation (Bellaire). Bellaire manages long-term liabilities related to former Eastern U.S. underground mining activities. During 2025, we changed the names of our reportable segments to make it easier for our stakeholders to understand the business activities within each segment. The Utility Coal Mining, Contract Mining and Minerals and Royalties segments were formerly the Coal Mining, North American Mining and Minerals Management segments, respectively. There were no changes to the composition of each segment and therefore no changes to historical segment reporting. See Note 15 to the Consolidated Financial Statements for further discussion of segment reporting. Our operating segments are further described below: Utility Coal Mining Segment The Utility Coal Mining segment operates surface coal mines under exclusive, long-term contracts to supply 100% of the fuel requirements for adjacent power plants and a synfuels plant. Each mine is fully integrated with the operation of these facilities. As of December 31, 2025, the Utility Coal Mining segment's operating coal mines were: The Coteau Properties Company (Coteau), Coyote Creek Mining Company, LLC (Coyote Creek), The Falkirk Mining Company (Falkirk) and Mississippi Lignite Mining Company (MLMC). Coteau, Falkirk and Coyote Creek are in North Dakota and MLMC is in Mississippi. Each of these mines produce lignite coal. While MLMC’s coal supply contract contains a take or pay provision, all other coal supply contracts are requirements contracts. Certain coal supply contracts can be terminated early, which would result in a reduction to future earnings. The MLMC contract is the only coal supply contract in which we are responsible for all operating costs, capital requirements and final mine reclamation; therefore, MLMC is consolidated within our financial statements. MLMC sells coal to its customer at a contractually agreed-upon price which adjusts monthly, primarily based on changes in the level of established indices which reflect general U.S. inflation rates and includes adjustments for coal quality and certain reimbursable costs. Profitability at MLMC is affected by customer demand for coal, changes in the contractually determined sales price and actual costs incurred. MLMC's customer operates the Red Hills Power Plant, which supplies electricity to the Tennessee Valley Authority (TVA) under a long-term power purchase agreement. MLMC’s contract with its customer runs through April 1, 2032. Current mine area reserves are sufficient to meet contractual requirements through the 2032 contract term. TVA’s power portfolio includes coal, nuclear, hydroelectric, natural gas and renewables. The decision regarding which power plants to dispatch is determined by TVA. As a significant portion of MLMC’s costs are fixed, reduction in dispatch and/or reduced mechanical availability of the Red Hills Power Plant can materially reduce operating results at MLMC. Conversely, periods of higher NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share, Percentage Data and Oil and Gas Disclosures) F-11
dispatch can improve results. The Red Hills Power Plant operated at below full baseload capacity and experienced periods of reduced mechanical availability during 2024 and 2025. These factors increased per ton operating costs which adversely affected operating results in both 2024 and 2025. In December 2023, MLMC received notice from its customer related to a boiler issue at the Red Hills Power Plant. While this issue has been resolved, it resulted in a reduction in customer demand which had a significant impact on our results of operations during 2024. We recognized income of $13.6 million in 2024 related to business interruption insurance recoveries that partially offset losses related to the boiler outage. The Sabine Mining Company (Sabine) operates the Sabine Mine in Texas. All production from Sabine was delivered to Southwestern Electric Power Company's (SWEPCO) Henry W. Pirkey Plant (the Pirkey Plant). SWEPCO is an American Electric Power (AEP) company. As a result of the early retirement of the Pirkey Plant, Sabine ceased deliveries and commenced final reclamation on April 1, 2023. Funding for mine reclamation is the responsibility of SWEPCO, and Sabine receives compensation for providing mine reclamation services. Sabine will provide mine reclamation services through September 30, 2026. As of October 1, 2026, SWEPCO is obligated to acquire all of the capital stock of Sabine and complete the remaining mine reclamation. At Coteau, Coyote Creek and Falkirk, we are paid a management fee per ton of coal or heating unit (MMBtu) delivered. Each contract specifies the indices and mechanics by which fees change over time, generally in line with broad measures of U.S. inflation. Our customers are responsible for funding all mine operating costs, including final mine reclamation, and directly or indirectly providing all of the capital required to build and operate the mine. This contract structure eliminates exposure to spot coal market price fluctuations while providing predictable income and cash flow with minimal capital investment. Other than at Coyote Creek, debt financing provided by or supported by the customers is without recourse to us. See Note 16 to the Consolidated Financial Statements in this Form 10-K for further discussion of Coyote Creek's guarantees. Coteau, Coyote Creek, Falkirk and Sabine each meet the definition of a variable interest entity (VIE). In each case, NACCO is not the primary beneficiary of the VIE as we do not exercise financial control; therefore, we do not consolidate the results of these operations within our financial statements. Instead, these contracts are accounted for as equity method investments. We regularly evaluate if there are reconsideration events which could change our conclusion as to whether these entities meet the definition of a VIE and the determination of the primary beneficiary. The income before income taxes associated with these VIEs is reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations and our investment is reported on the line Investments in unconsolidated subsidiaries in the Consolidated Balance Sheets. The mines that meet the definition of a VIE are referred to collectively as the Unconsolidated Subsidiaries. For tax purposes, the Unconsolidated Subsidiaries are included within our consolidated U.S. tax return; therefore, the Income tax benefit line on the Consolidated Statements of Operations includes income taxes related to these entities. See Note 16 to the Consolidated Financial Statements in this Form 10-K for further information on the Unconsolidated Subsidiaries. We perform contemporaneous reclamation activities at each mine in the normal course of operations. Under all of the Unconsolidated Subsidiaries’ contracts, the customer has the obligation to fund final mine reclamation activities. Under certain contracts, the Unconsolidated Subsidiary holds the mine permit and is therefore responsible for final mine reclamation activities. To the extent the Unconsolidated Subsidiary performs such final reclamation, it is compensated for providing those services in addition to receiving reimbursement from customers for costs incurred. Contract Mining Segment The Contract Mining segment provides value-added contract mining and other services for producers of industrial minerals and products. The segment is a platform for our growth and diversification of mining activities outside of the thermal coal industry. Contract Mining provides contract mining services for independently owned mines and quarries, creating value for our customers by performing the mining aspects of our customers’ operations. This allows customers to focus on their areas of expertise: materials handling and processing, product sales and distribution. As of December 31, 2025, the Contract Mining segment operates at quarries in Florida, Arkansas and Nebraska and is expected to begin operations at a quarry in Arizona during the first half of 2026. Beginning in 2026, the Contract Mining segment will also provide dragline services as part of a U.S. Army Corps of Engineers construction project in Palm Beach County, Florida. In addition, Contract Mining's subsidiary, Sawtooth, is the exclusive provider of comprehensive mining services for the Thacker Pass lithium project in Humboldt County, Nevada. Thacker Pass is owned by a joint venture between Lithium NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share, Percentage Data and Oil and Gas Disclosures) F-12
Americas Corp. (TSX:LAC) (NYSE: LAC) and General Motors Holdings LLC. The U.S. Department of Energy holds warrants to purchase five percent non-voting, non-transferable equity in this joint venture. Thacker Pass is targeting initial lithium production in late 2027. The contract requires reimbursement for costs of mining, capital expenditures and mine closure. Sawtooth will recognize a contractually agreed upon production fee once the mine is operating. In addition to providing comprehensive mining services, Sawtooth is currently assisting with certain construction services and will transport clay tailings once lithium production commences. Minerals and Royalties Segment The Minerals and Royalties segment derives income primarily by leasing our royalty and mineral interests to third-party exploration and production companies, and, to a lesser extent, other mining companies, granting them the rights to explore, develop, mine, produce, market and sell gas, oil, and coal in exchange for royalty payments based on the lessees' sales of those minerals. The Minerals and Royalties segment owns royalty interests, mineral interests, non-participating royalty interests and overriding royalty interests (collectively mineral and royalty interests). • Royalty Interest. Royalty interests generally result when the owner of a mineral interest leases the underlying minerals to an exploration and production company pursuant to an oil and gas lease. Typically, the resulting royalty interest is a cost-free percentage of production revenues for minerals extracted from the acreage. A holder of royalty interests is generally not responsible for capital expenditures or lease operating expenses, but royalty interests may be calculated net of post-production expenses. Royalty interests leased to producers expire upon the expiration of the oil and gas lease and revert to the mineral owner. • Mineral Interest. Mineral interests are perpetual rights of the owner to explore, develop, exploit, mine and/or produce any or all of the minerals lying below the surface of the property. The holder of a mineral interest has the right to lease the minerals to an exploration and production company. Upon the execution of an oil and gas lease, the lessee (the exploration and production company) becomes the working interest owner and the lessor (the mineral interest owner) has a royalty interest. • Non-Participating Royalty Interest (NPRIs). NPRI is an interest in oil and gas production which is created from the mineral estate. The NPRI is expense-free, bearing no operational costs of production. The term non-participating indicates that the interest owner does not share in the bonus, rentals from a lease, nor the right to participate in the execution of oil and gas leases. The NPRI owner does; however, typically receive royalty payments. • Overriding Royalty Interest (ORRIs). ORRIs are created by carving out the right to receive royalties from a working interest. Like royalty interests, ORRIs do not confer an obligation to make capital expenditures or pay for lease operating expenses and have limited environmental liability; however, ORRIs may be calculated net of post- production expenses, depending on how the ORRI is structured. ORRIs that are carved out of working interests are linked to the same underlying oil and gas lease that created the working interest, and therefore, such ORRIs are typically subject to expiration upon the expiration or termination of the oil and gas lease. We may own more than one type of mineral and royalty interest in the same tract of land. For example, where we own an ORRI in a lease on the same tract of land in which we own a mineral interest, the ORRI in that tract will relate to the same gross acres as the mineral interest in that tract. As of December 31, 2025 and 2024, the Minerals and Royalties segment holds an equity investment of $33.7 million and $19.1 million, respectively, in Eiger Resources, which holds operated and non-operated working interests in oil and natural gas assets in the Kansas and the Oklahoma portion of the Hugoton basin. Although we own less than 20%, Eiger Resources meets the definition of a VIE. NACCO is not the primary beneficiary of the VIE as it does not exercise financial control; therefore, we do not consolidate the results of these operations within our financial statements. Instead, this contract is accounted for as an equity method investment. Our investment is reported on the line Equity method investment in Eiger Resources in the Consolidated Balance Sheets. The Minerals and Royalties segment records its share of earnings as Earnings of unconsolidated operations on the Consolidated Statements of Operations. Due to the timing and availability of financial information, earnings or losses from this investment are recorded on a one quarter lag.

Changes in the Eiger Resources equity method investment balance are summarized as follows: December 31 2025 2024 Beginning balance $ 19,147 $ 2,800 Share of earnings 2,571 647 Capital contributions 15,000 15,700 Distributions received (2,995) — Ending balance $ 33,723 $ 19,147 Excluding the Eiger Resources investment described above, total consideration for acquisitions of mineral and royalty interests was $4.7 million and $0.7 million, in 2025 and 2024, respectively. The 2025 acquisitions include 10.5 thousand gross acres and 0.4 thousand net royalty acres. The 2024 acquisitions included 13.7 thousand gross acres and 0.6 thousand net royalty acres. The Minerals and Royalties segment also manages legacy royalty and mineral interests located in Ohio (Utica and Marcellus shale natural gas), Louisiana (Haynesville shale and Cotton Valley formation natural gas), Texas (Cotton Valley and Austin Chalk formation natural gas), Mississippi (coal), Pennsylvania (coal, coalbed methane and Marcellus shale natural gas), Alabama (coal, coalbed methane and natural gas) and North Dakota (coal, oil and natural gas). The majority of our legacy reserves were acquired as part of our historical coal mining operations. Total oil and gas mineral and royalty interests include approximately 208.0 thousand gross acres and 64.4 thousand net royalty acres at December 31, 2025. Net royalty acres are calculated based on our ownership and royalty rate, normalized to a standard 1/8th royalty lease, and assumes a 1/4th royalty rate for unleased acres. See Note 17 for further discussion of Minerals and Royalties. Other items: At December 31, 2025 and 2024, we had $12.8 million and $14.2 million classified as Assets held for sale on the Consolidated Balance Sheets. During 2025, we sold three draglines that were classified as Assets held for sale as of December 31, 2024 and recognized a $0.1 million gain in the Contract Mining segment, which is included on the line Gain on sale of assets within the Consolidated Statements of Operations. At December 31, 2025, Assets held for sale consists of two draglines not in use in the Contract Mining Segment and an office building in North Dakota in Unallocated Items. During 2025, we terminated the NACCO Combined Defined Benefit Plan (Combined Plan) and settled all future obligations by transferring the remaining benefit obligations to a third-party insurance company. Although the plan was overfunded, we recognized a non-cash, pension settlement charge of $7.8 million on the line Pension settlement charge within the Consolidated Statements of Operations. The $7.8 million settlement charge accelerated the recognition of the net loss recorded in Accumulated other comprehensive loss that would have otherwise been recognized in subsequent periods. See Note 14 to the Consolidated Financial Statements in this Form 10-K for further information on the Combined Plan. During 2025, the Company and Falkirk’s former customer agreed to settle the Falkirk Defined Benefit Plan for $10.9 million, resulting in a gain of $3.6 million on the line Gain on settlement of excess funding liability within the Consolidated Statements of Operations. In accordance with the agreement reached with the former customer, $5.5 million was paid to the former customer during 2025. The remaining $5.4 million, recorded on the line Excess funding liability on the Consolidated Balance Sheets at December 31, 2025, will be paid to the former customer in 2026. The excess funds from the terminated Combined Plan and the Falkirk Defined Benefit Plan will be utilized by the NACCO 401(k) plan, which is a qualified replacement plan. These funds will be used for future profit sharing contributions to eligible 401(k) plan participants. Total remaining funds are $14.6 million as of December 31, 2025. The current portion of $11.5 million is recorded on the line Prepaid profit sharing and the long-term portion of $3.1 million is recorded on the line Other non-current assets on the Consolidated Balance Sheet as of December 31, 2025. During 2024, we sold land for $7.0 million and recognized a $4.5 million gain in the Minerals and Royalties segment, which is included on the line Gain on sale of assets within the Consolidated Statements of Operations.

NOTE 2—Significant Accounting Policies Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and judgments. These estimates and judgments affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities (if any) at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents: Cash and cash equivalents include cash in banks and highly liquid investments with original maturities of three months or less. Property, Plant and Equipment, Net: Property, plant and equipment are initially recorded at cost. Depreciation, depletion and amortization are provided in amounts sufficient to amortize the cost of the assets, including assets recorded under finance leases, over their estimated useful lives using the straight-line method or the units-of-production method. Buildings and building improvements are depreciated over the life of the asset, which is generally 30 years. Estimated lives for machinery and equipment generally range from three to 15 years. The units-of-production method is used to amortize certain assets based on estimated recoverable tonnages. Repairs and maintenance costs are expensed when incurred, unless such costs extend the estimated useful life of the asset, in which case such costs are capitalized and depreciated. Asset retirement costs associated with asset retirement obligations are capitalized with the carrying amount of the related long-lived asset and depreciated over the asset's estimated useful life. Royalty Interests in Oil and Natural Gas Properties: We follow the successful efforts method of accounting for royalty and mineral interests. Under this method, costs to acquire mineral and royalty interests in oil and natural gas properties are capitalized when incurred. Acquisitions of royalty interests of oil and natural gas properties are considered asset acquisitions and are recorded at cost. Acquisition costs of proved royalty and mineral interests are amortized using the units of production method over the life of the property, which is estimated using proved reserves. For purposes of amortization, interests in oil and natural gas properties are grouped in a reasonable aggregation of properties. We review and evaluate our royalty interests in oil and natural gas properties for impairment when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Proved oil and gas properties are reviewed for impairment when events and circumstances indicate a potential decline in the fair value of such properties below the carrying value, such as a downward revision of the reserve estimates or lower commodity prices. When such events or changes in circumstances occur, we estimate the undiscounted future cash flows expected in connection with the properties and compare such future cash flows to the carrying amounts of the properties to determine if the carrying amounts are recoverable. If the carrying value of the properties is determined to not be recoverable based on the undiscounted cash flows, an impairment charge is recognized by comparing the carrying value to the estimated fair value of the properties. See Note 17 for further discussion of our royalty and mineral interests. Long-Lived Assets: We periodically evaluate long-lived assets for impairment when changes in circumstances or the occurrence of certain events indicate the carrying amount of an asset or asset group may not be recoverable. Upon identification of indicators of impairment, we evaluate the carrying value of the asset by comparing the estimated future undiscounted cash flows generated from the use of the asset or asset group and its eventual disposition with the asset's net carrying value. If the carrying value of an asset is considered impaired, an impairment charge is recorded for the amount that the carrying value of the long-lived asset or asset group exceeds its fair value. Fair value is estimated as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Self-insurance Liabilities: We are generally self-insured for medical claims, certain workers’ compensation claims and certain closed mine liabilities. An estimated provision for claims reported and for claims incurred but not yet reported under the self- insurance programs is recorded and revised periodically based on industry trends, historical experience and management judgment. In addition, industry trends are considered within management's judgment for valuing claims. Changes in assumptions for such matters as legal judgments and settlements, inflation rates, medical costs and actual experience could cause estimates to change in the near term. Revenue Recognition: See Note 3 to the Consolidated Financial Statements for discussion of our revenue recognition. Stock Compensation: We maintain a long-term incentive program that allow for the grant of shares of Class A common stock, subject to restrictions, as a means of retaining and rewarding selected employees for long-term performance and to increase their ownership in NACCO. Shares awarded under the plans are fully vested and entitle the stockholder to all rights of common NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share, Percentage Data and Oil and Gas Disclosures) F-15
stock ownership except that shares may not be assigned, pledged or otherwise transferred during the restriction period. In general, for shares awarded for years ended December 31, 2025 and December 31, 2024, the restriction period ends at the earliest of (i) three years after the participant's retirement date, (ii) three, five or ten years from the award date, or (iii) the participant's death or permanent disability. Pursuant to the plans, we issued 124,401 and 162,670 shares related to the years ended December 31, 2025 and 2024, respectively. After the issuance of these shares, there were 492,280 shares of Class A common stock available for issuance under these plans. Compensation expense related to these share awards was $7.1 million ($5.6 million net of tax) and $5.2 million ($4.1 million net of tax) for the years ended December 31, 2025 and 2024, respectively. Compensation expense represents fair value based on the market price of the shares of Class A common stock at the grant date. We also have a stock compensation plan for non-employee directors under which a portion of the annual retainer for each non- employee director is paid in restricted shares of Class A common stock. For the year ended December 31, 2025, $112,000 ($195,000 for the Chairman) of the non-employee director's annual retainer of $179,000 ($300,000 for the Chairman) was paid in restricted shares of Class A common stock. For the year ended December 31, 2024, $110,000 ($150,000 for the Chairman) of the non-employee director's annual retainer of $175,000 ($250,000 for the Chairman) was paid in restricted shares of Class A common stock. Shares awarded under the plan are fully vested and entitle the stockholder to all rights of common stock ownership except that shares may not be assigned, pledged, hypothecated or otherwise transferred during the restriction period. In general, the restriction period ends at the earliest of (i) ten years from the award date, (ii) the date of the director's death or permanent disability, (iii) five years (or earlier with the approval of the Board of Directors) after the director's date of retirement from the Board of Directors, (iv) the date the director has both retired from the Board of Directors and has reached age 70, or (v) at such other time as determined by the Board of Directors in their sole and absolute discretion. Pursuant to this plan, we issued 35,372 and 44,731 shares related to the years ended December 31, 2025 and 2024, respectively. In addition to the mandatory retainer fee received in restricted stock, directors may elect to receive shares of Class A common stock in lieu of cash for up to 100% of the balance of their annual retainer, committee retainer and any committee chairman's fees. These voluntary shares are not subject to any restrictions. There were no shares issued under voluntary elections in 2025 and 2024. After the issuance of these shares, there were 175,687 shares of Class A common stock available for issuance under this plan. Compensation expense related to these awards was $1.5 million ($1.2 million net of tax) and $1.3 million ($1.0 million net of tax) for the years ended December 31, 2025 and 2024, respectively. Compensation expense represents fair value based on the market price of the shares of Class A common stock at the grant date. Financial Instruments: Financial instruments held by us include cash and cash equivalents, accounts receivable, equity securities, accounts payable, revolving credit agreements and long-term debt. Fair Value Measurements: We account for the fair value measurement of our financial assets and liabilities in accordance with U.S. generally accepted accounting principles, which defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value hierarchy requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. Described below are the three levels of inputs that may be used to measure fair value: Level 1 - Quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities. Level 2 - Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. Level 3 - Unobservable inputs are used when little or no market data is available. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement. See Note 9 for further discussion of fair value measurements. Recently Issued Accounting Standards Accounting Standards Adopted in 2025: During 2025, we adopted ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09) on a prospective basis, which requires entities to disclose more detailed information about their effective tax rate reconciliation as well as information on income taxes paid. The adoption of this standard only impacts disclosures and did not have a material impact on our Financial Statements. Accounting Standards Not Yet Adopted: In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) (ASU 2024-03), which requires NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share, Percentage Data and Oil and Gas Disclosures) F-16
entities to disclose disaggregated information about certain income statement expense line items in the notes to their financial statements on an annual and interim basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. We are currently in the process of evaluating the impact of this ASU on our Financial Statements and related disclosures. Reclassification: Certain reclassifications have been made to the prior periods’ Consolidated Financial Statements to conform to the current period's presentation. NOTE 3—Revenue Recognition Nature of Performance Obligations: At contract inception, we assess the goods and services promised in our contracts with customers and identify a performance obligation for each promised good or service that is distinct. To identify the performance obligations, we consider all of the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. Each mine or mine area has a contract with our respective customer that represents a contract under ASC 606. For our consolidated entities, our performance obligations vary by contract and consist of the following: At MLMC, each MMBtu delivered during the production period is considered a separate performance obligation. Revenue is recognized at the point in time that control of each MMBtu of lignite transfers to the customer. Fluctuations in revenue from period to period generally result from changes in customer demand. In the Contract Mining segment, the management service to oversee the operation of the equipment and delivery of aggregates or other minerals is the performance obligation accounted for as a series. Performance momentarily creates an asset that the customer simultaneously receives and consumes; therefore, control is transferred to the customer over time. Consistent with the conclusion that the customer simultaneously receives and consumes the benefits provided, an input-based measure of progress is appropriate. As each month of service is completed, revenue is recognized for the amount of actual costs incurred, plus the management fee or fixed fee and the general and administrative fee (as applicable). Fluctuations in revenue from period to period result from changes in customer demand primarily due to increases and decreases in activity levels on individual contracts and variances in reimbursable costs. Revenue from equipment sales and part sales is recognized upon transfer of control to the customer. The Minerals and Royalties segment enters into contracts which grant the right to explore, develop, produce and sell minerals controlled by us. These arrangements result in the transfer of mineral rights for a period of time; however, no rights to the actual land are granted other than access for purposes of exploration, development, production and sales. The mineral rights revert back to us at the expiration of the contract. Under these contracts, granting exclusive right, title, and interest in and to minerals, if any, is the performance obligation. The performance obligation under these contracts represents a series of distinct goods or services whereby each day of access that is provided is distinct. The transaction price consists of a variable sales-based royalty and, in certain arrangements, a fixed component in the form of an up-front lease bonus payment. As the amount of consideration we will ultimately be entitled to is entirely susceptible to factors outside of our control, the entire amount of variable consideration is constrained at contract inception. We believe that the pricing provisions of royalty contracts are customary in the industry. Mitigation Resources provides natural resource restoration and reclamation services that include stream and wetland mitigation solutions. For restoration and reclamation services, the service contracts are generally structured as an agreement under which Mitigation Resources is reimbursed for all costs incurred plus a fixed fee. The services provided represent the performance obligation and are accounted for as a series. Performance momentarily creates an asset that the customer simultaneously receives and consumes; therefore, control is transferred to the customer as work is completed. Consistent with the conclusion that the customer simultaneously receives and consumes the benefits provided, an input-based measure of progress is appropriate. As each month of service is completed, revenue is recognized for the amount of actual costs incurred, plus the fixed fee. Fluctuations in revenue from period to period result from increases and decreases in activity levels of individual contracts and variances in reimbursable costs. Mitigation Resources also generates and sells stream and wetland mitigation credits (known as mitigation banking). In mitigation banking, each mitigation credit sale is considered a separate performance obligation. Mitigation banks are regulated NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share, Percentage Data and Oil and Gas Disclosures) F-17
and approved by the U.S. Army Corps of Engineers and other federal, state and local agencies. Mitigation credits are released in phases over the life of the mitigation bank. Revenue is recognized at the point in time that control of each mitigation credit transfers to the customer. Fluctuations in revenue from period to period generally result from changes in timing of mitigation credit releases and/or customer demand. Significant Judgments: The contracts with our customers in the Utility Coal Mining and Contract Mining segments contain different types of variable consideration including, but not limited to, management fees that adjust based on volumes or MMBtu delivered. However, the terms of these variable payments relate specifically to our efforts to satisfy one or more, but not all, of the performance obligations (or to a specific outcome from satisfying the performance obligations) in the contract. Therefore, we allocate each variable payment (and subsequent changes to that payment) entirely to the specific performance obligation to which it relates. Management fees, as well as general and administrative fees, are also adjusted based on changes in specified indices (e.g., CPI) to compensate for general inflation changes. Index adjustments, if applicable, are effective prospectively. In the Minerals and Royalties segment, we have the right to receive revenues from the sale of oil and natural gas through sales of the third-party lessees in which we own a mineral or royalty interest. Revenue is recognized at the point control of the product is transferred from the operator to the purchaser. Those purchasers remit payment to the operator and the operator, in turn, remits payment to us. Receivables from third-party lessees for which we did not receive actual production information, either due to timing delays or due to the unavailability of data at the time when revenues are recognized, are estimated using expected sales volumes and estimated prices. The difference between our estimates and the actual amounts received is recorded in the month that payment is received from the third-party lessee. We typically receive payment for oil and natural gas sales within 90 days of the month of delivery. For the years ended December 31, 2025 and 2024, differences between our estimates and the actual amounts received from operators were immaterial. Cost Reimbursement: Certain contracts include reimbursement from customers of actual costs incurred for the purchase of supplies, equipment and services in accordance with contractual terms. Such reimbursable revenue is variable and subject to uncertainty, as the amounts received and timing thereof is highly dependent on factors outside of our control. Accordingly, reimbursable revenue is fully constrained and not recognized until the uncertainty is resolved, which typically occurs when the related costs are incurred on behalf of a customer. We are considered a principal in such transactions and record the associated revenue at the gross amount billed to the customer with the related costs recorded as an expense within cost of sales. At the Thacker Pass lithium project, in addition to management fee income, the customer will reimburse Sawtooth for certain capital expenditures. Sawtooth will recognize revenue over the estimated useful life of the asset on a straight-line basis as the performance obligation is satisfied over time. In prior years, the customer received a $3.5 million advance from Sawtooth, which is included in the long-term contract asset. The customer will pay a $4.7 million success fee to Sawtooth if commercial mining milestones are met, at which time Sawtooth will recognize the revenue for the difference between the success fee and the amount advanced. If commercial mining milestones are not met, the customer will only repay the $3.5 million advance. Prior Period Performance Obligations: As discussed above, we record royalty income in the month production is delivered to the purchaser. The expected sales volumes and prices for these properties are estimated and recorded in Other current assets in the Consolidated Balance Sheets. The difference between our estimates and the actual amounts received is recorded in the month that payment is received from the third-party lessee. During the years ended December 31, 2025 and 2024, royalty income recognized in the reporting period relating to production satisfied in prior periods was $1.5 million and immaterial, respectively. Disaggregation of Revenue: In accordance with ASC 606-10-50, we disaggregate revenue from contracts with customers into major goods and service lines and timing of transfer of goods and services. We determined that disaggregating revenue into these categories achieves the disclosure objective of depicting how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. Our business consists of the Utility Coal Mining, Contract Mining and Minerals and Royalties segments as well as Unallocated Items. Revenue included in Unallocated Items is primarily related to Mitigation Resources. See Note 15 to the Consolidated Financial Statements for further discussion of segment reporting.

The following table disaggregates revenue by major sources for the years ended December 31: Major Goods/Service Lines 2025 2024 Utility Coal Mining $ 88,188 $ 68,611 Contract Mining 140,013 119,600 Minerals and Royalties 37,630 34,579 Unallocated Items 15,080 17,707 Eliminations (3,713) (2,789) Total revenues $ 277,198 $ 237,708 Timing of Revenue Recognition Transferred at a point in time $ 92,331 $ 66,506 Transferred over time 184,867 171,202 Total revenues $ 277,198 $ 237,708 Contract Balances The opening and closing balances of our current and long-term contract assets and liabilities and receivables are as follows: Contract balances Trade accounts receivable Contract asset (current) Contract asset (long-term) Contract liability (current) Contract liability (long-term) Balance at January 1, 2025 $ 49,706 $ 313 $ 3,500 $ 484 $ 5,119 Balance at December 31, 2025 42,921 382 3,500 1,358 10,593 Increase (decrease) $ (6,785) $ 69 $ — $ 874 $ 5,474 We expect to recognize $1.4 million in 2026, $0.3 million in 2027, $1.2 million in 2028, $0.2 million in 2029 and 2030 and $8.7 million thereafter related to the contract liability remaining at December 31, 2025. The difference between the opening and closing balances of our contract balances results from the timing difference between our performance and the customer’s payment. We have no contract assets recognized from the costs to obtain or fulfill a contract with a customer. NOTE 4—Inventories Inventories are summarized as follows: December 31 2025 2024 Coal $ 24,585 $ 27,076 Mining supplies 73,858 67,532 Total inventories $ 98,443 $ 94,608 The weighted average method is used for inventory valuation. During the year ended December 31, 2025 and 2024, we recorded $7.0 million and $9.6 million of inventory impairment charges, respectively, in the line Cost of sales in the Consolidated Statements of Operations as mining costs exceeded net realizable value of coal inventory at MLMC. Mining supplies inventory consists primarily of critical spare parts to support Contract Mining’s dragline operations and other general supplies used on day-to-day operations. Mining supplies inventory not expected to be utilized within the next 12 months is classified as long-term on the Consolidated Balance Sheet.

NOTE 5—Property, Plant and Equipment, Net Property, plant and equipment, net includes the following: December 31 2025 2024 Coal lands and real estate $ 72,490 $ 70,766 Mineral interests 73,850 69,148 Plant and equipment 354,447 317,933 Property, plant and equipment, at cost 500,787 457,847 Less allowances for depreciation, depletion and amortization 213,241 198,390 $ 287,546 $ 259,457 Total depreciation, depletion and amortization expense on property, plant and equipment was $24.5 million and $24.1 million during 2025 and 2024, respectively. NOTE 6—Intangible Assets We have a coal supply agreement intangible asset which is subject to amortization based on units of production over the term of the lignite sales agreement which expires in 2032. The gross and net balances are set forth in the following table: Gross Carrying Amount Accumulated Amortization and Impairment Net Balance Balance at December 31, 2025 Coal supply agreement $ 84,200 $ (79,475) $ 4,725 Balance at December 31, 2024 Coal supply agreement $ 84,200 $ (78,725) $ 5,475 Amortization expense for intangible assets was $0.8 million and $0.5 million in 2025 and 2024, respectively. NOTE 7—Asset Retirement Obligations Our obligations associated with the retirement of long-lived assets are recognized at fair value at the time the legal obligations are incurred. Upon initial recognition of a liability, a corresponding amount is capitalized as part of the carrying value of the related long-lived asset within Property, Plant and Equipment, net in the Consolidated Balance Sheets. The asset is depreciated either by the straight-line method or the units-of-production method. The liability is accreted each period until the liability is settled, at which time the liability is removed. The depreciation of the asset and the accretion of the liability are both recorded in the line Cost of sales in the Consolidated Statements of Operations. If the liability is settled for an amount other than the recorded amount, a gain or loss is recognized. Our asset retirement obligations are principally for costs to close our consolidated surface mines and reclaim the land as a result of our normal mining activities. Management’s estimate involves a high degree of subjectivity. In particular, the obligation’s fair value is determined using a discounted cash flow technique and is based upon mining permit requirements and various assumptions including credit adjusted risk-free-rates, estimates of disturbed acreage, life of the mine, estimated reclamation costs, the application of various environmental laws and regulations and assumptions regarding equipment productivity.

A reconciliation of our beginning and ending aggregate carrying amount of the asset retirement obligations are as follows: Utility Coal Mining Unallocated Items NACCO Consolidated Balance at January 1, 2024 $ 33,044 $ 19,569 $ 52,613 Liabilities settled during the period (6,115) (960) (7,075) Accretion expense 2,530 1,510 4,040 Revision of estimated cash flows 79 (130) (51) Balance at December 31, 2024 $ 29,538 $ 19,989 $ 49,527 Liabilities settled during the period (5,491) (1,269) (6,760) Accretion expense 2,284 1,553 3,837 Revision of estimated cash flows 2,246 (1,149) 1,097 Balance at December 31, 2025 $ 28,577 $ 19,124 $ 47,701 Bellaire's legacy liabilities include obligations for water treatment and other environmental remediation that arose as part of the normal course of closing these underground mining operations. Since Bellaire's properties are no longer active operations, no associated asset has been capitalized. Bellaire’s asset retirement obligation is included in the table above in the Unallocated Items column. In a previous period, Bellaire established a $5.0 million Mine Water Treatment Trust, which is legally restricted for purposes of settling the Bellaire asset retirement obligation, to assure the long-term treatment of post-mining discharges. The fair value of Bellaire's Mine Water Treatment assets are $13.5 million and $12.3 million at December 31, 2025 and December 31, 2024, respectively, and is recognized as a component of Equity securities in the Consolidated Balance Sheets. See Note 9 for further discussion of the Mine Water Treatment Trust. NOTE 8—Current and Long-Term Financing Financing arrangements are obtained and maintained at the subsidiary level. NACCO has not guaranteed any borrowings of our subsidiaries.

Interest capitalized was $1.5 million during 2025. In September 2024, NACCO Natural Resources amended its secured revolving line of credit (Facility) to increase the revolving credit commitments to $200.0 million and extend the maturity to September 2028. Borrowings outstanding under the Facility were $75.0 million at December 31, 2025. At December 31, 2025, the excess availability under the Facility was $74.5 million, which reflects a reduction for outstanding letters of credit of $50.5 million. The Facility has performance-based pricing, which sets interest rates based upon NACCO Natural Resources achieving various levels of debt to EBITDA ratios, as defined in the Facility. Borrowings bear interest at a floating rate plus a margin based on the level of debt to EBITDA ratio achieved. The applicable margins, effective December 31, 2025, for base rate and Term Secured Overnight Financing Rate loans were 1.50% and 2.50%, respectively. The Facility has a commitment fee which is based upon achieving various levels of net debt to EBITDA ratios. The commitment fee was 0.40% on the unused commitment at December 31, 2025. During the year ended December 31, 2025 and December 31, 2024, the average borrowing under the Facility was $57.3 million and $27.2 million, respectively, and the weighted-average annual interest rate, including the floating rate margin, was 7.21% and 8.83%, respectively. The Facility contains restrictive covenants, which require, among other things, NACCO Natural Resources to maintain a maximum net debt to EBITDA ratio of 2.75 to 1.00 and an interest coverage ratio of not less than 4.00 to 1.00. The Facility provides the ability to make loans, dividends and advances to NACCO, with some restrictions based on maintaining a maximum debt to EBITDA ratio of 1.50 to 1.00, or if greater than 1.50 to 1.00, a Fixed Charge Coverage Ratio of 1.10 to 1.00. At December 31, 2025, NACCO Natural Resources was in compliance with all financial covenants in the Facility. The obligations under the Facility are guaranteed by certain of NACCO Natural Resources' direct and indirect, existing and future domestic subsidiaries, and is secured by certain assets of NACCO Natural Resources and the guarantors, subject to customary exceptions and limitations. We have a demand note payable to Coteau, one of the unconsolidated subsidiaries, which bears interest based on the applicable quarterly federal short-term interest rate as announced from time to time by the IRS. At December 31, 2025 and 2024, the balance of the note was $7.3 million and $7.7 million and the interest rate was 3.75% and 4.15%, respectively. We have ten notes payable that are secured by twelve specified units of equipment, bear interest at a weighted average rate of 5.48%, and expire at various dates through 2030. One note includes a principal payment of $4.4 million at the end of the term on December 15, 2026. At December 31, 2025 and 2024, the outstanding balances of the notes payable were $18.5 million and $21.8 million, respectively. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC.

The fair value of the Mine Water Treatment Trust was $13.5 million and $12.3 million at December 31, 2025 and December 31, 2024, respectively, and is recognized as a component of Equity securities in the Consolidated Balance Sheets. We recognized gains of $1.4 million and $1.5 million in the years ended December 31, 2025 and 2024, respectively, related to the Mine Water Treatment Trust. See Note 7 for further discussion of Bellaire's Mine Water Treatment Trust. In a previous period, we invested $2.0 million in equity securities of a public company with a diversified portfolio of royalty producing mineral interests. The investment is reported at fair value based upon quoted market prices in active markets for identical assets; therefore, it is classified as Level 1 within the fair value hierarchy. The fair value of this investment was $4.2 million and $6.3 million at December 31, 2025 and December 31, 2024, respectively, and is recognized as a component of Equity securities in the Consolidated Balance Sheets. We recognized a loss of $2.1 million and a gain of $0.3 million in the years ended December 31, 2025 and 2024, respectively, related to the investment in these equity securities. The change in fair value of equity securities is reported on the line Loss (gain) on equity securities in the Other expense (income) section of the Consolidated Statements of Operations. In 2025, excess funds from the terminated Combined Plan and the Falkirk Defined Benefit Plan were transferred to a separate investment account. These funds will be utilized for future profit sharing contributions to eligible 401(k) plan participants. The Prepaid profit sharing balance is reported at fair value based upon quoted market prices in active markets for identical assets; therefore, it is classified as Level 1 within the fair value hierarchy. See Note 1 for further discussion of the Prepaid profit sharing balance. There were no transfers into or out of Levels 1, 2 or 3 during the years ended December 31, 2025 and 2024. Other Fair Value Measurement Disclosures: The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term maturities of these instruments. The fair values of revolving credit agreements and long-term debt, excluding finance leases, were determined using current rates offered for similar obligations taking into account subsidiary credit risk, which is Level 2 as defined in the fair value hierarchy. The fair value and the book value of revolving credit agreements and long-term debt, excluding finance leases, was $100.1 million and $100.8 million, respectively, at December 31, 2025 and $97.9 million and $99.4 million, respectively, at December 31, 2024.

Financial instruments that potentially subject us to concentration of credit risk consist principally of accounts receivable. Under our mining contracts, we recognize revenue and a related receivable as coal or other aggregates are delivered or predevelopment services are provided. These mining contracts generally provide for settlements within 60 days. Our significant credit concentration is uncollateralized; however, historically minimal credit losses have been incurred. To further reduce credit risk associated with accounts receivable, we perform periodic credit evaluations of our customers, but do not generally require advance payments or collateral. NOTE 10—Leases We recognize right-of-use assets (ROU assets) and lease liabilities for operating leases of real estate, mining and other equipment that expire at various dates through 2036. The majority of our leases are operating leases. NACCO does not recognize leases with a term of 12 months or less on the balance sheet. Instead, we recognize the related lease expense on a straight-line basis over the lease term. We account for lease and non-lease components as a single lease component. Our lease agreements do not contain lease payments that depend on an index or a rate, as such, minimum lease payments do not include variable lease payments. Leased assets and liabilities include the following at December 31: Description Location 2025 2024 Assets Operating Operating lease right-of-use assets $ 9,595 $ 9,661 Finance Property, plant and equipment, net (a) 52 79 Liabilities Current Operating Other current liabilities $ 2,470 $ 1,973 Finance Current maturities of long-term debt 29 27 Non-current Operating Operating lease liabilities $ 7,950 $ 9,042 Finance Long-term debt 28 57 (a) Finance leased assets are recorded net of accumulated amortization of less than $0.1 million as of December 31, 2025 and December 31, 2024.

These proceedings and claims are incidental to the ordinary course of our business. Management believes that it has meritorious defenses and will vigorously defend us in these actions. Any costs that management estimates will be paid as a result of these claims are accrued when the liability is considered probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is probable or reasonably possible and which are material, we disclose the nature of the contingency and, in some circumstances, an estimate of the possible loss. These matters are subject to inherent uncertainties, and unfavorable rulings could occur. If an unfavorable ruling were to occur, there exists the possibility of an adverse impact on our financial position, results of operations and cash flows of the period in which the ruling occurs, or in future periods.

NOTE 12—Stockholders' Equity and Earnings Per Share NACCO Industries, Inc. Class A common stock is traded on the New York Stock Exchange under the ticker symbol NC. Because of transfer restrictions on Class B common stock, no trading market has developed, or is expected to develop, for our Class B common stock. The Class B common stock is convertible into Class A common stock on a one-for-one basis at any time at the request of the holder. Our Class A common stock and Class B common stock have the same cash dividend rights per share. As the liquidation and dividend rights are identical, any distribution of earnings would be allocated to Class A and Class B stockholders on a proportionate basis, and accordingly the net income per share for each class of common stock is identical. The Class A common stock has one vote per share and the Class B common stock has ten votes per share. The total number of authorized shares of Class A common stock and Class B common stock at December 31, 2025 was 25,000,000 shares and 6,756,176 shares, respectively. Treasury shares of Class A common stock totaling 2,356,755 and 2,488,013 at December 31, 2025 and 2024, respectively, have been deducted from shares outstanding. Stock Repurchase Program: On November 18, 2025, our Board of Directors approved a stock purchase program (2025 Stock Repurchase Program) providing for the purchase of up to $20.0 million of our outstanding Class A common stock through December 31, 2027. NACCO's previous repurchase program would have expired on December 31, 2025 but was terminated and replaced by the 2025 Stock Repurchase Program. During 2025, we repurchased 61,554 shares of Class A Common Stock for an aggregate purchase price of $2.5 million. During 2024, we repurchased 316,950 shares of Class A Common Stock for an aggregate purchase price of $9.9 million. The timing and amount of any repurchases under the 2025 Stock Repurchase Program are determined at the discretion of our management based on a number of factors, including the availability of capital, other capital allocation alternatives, market conditions for our Class A common stock and other legal and contractual restrictions. The 2025 Stock Repurchase Program does not require us to acquire any specific number of shares and may be modified, suspended, extended or terminated by us without prior notice and may be executed through open market purchases, privately negotiated transactions or otherwise. All or part of the repurchases under the 2025 Stock Repurchase Program may be implemented under a Rule 10b5-1 trading plan, which would allow repurchases under pre-set terms at times when we might otherwise be restricted from doing so under applicable securities laws.

NOTE 13—Income Taxes We provide for income taxes and the related accounts under the asset and liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates expected to be in effect during the year in which the basis differences reverse. Valuation allowances are established when management determines it is more likely than not that some portion, or all, of the deferred tax assets will not be realized.

The provision for income taxes differs from the amount computed by applying the statutory federal income tax rate to income before the provision for income taxes. A reconciliation of the federal statutory and effective income tax rate, applying ASU 2023-09 prospectively, for the year ended December 31 is as follows: 2025 Amount Percent Income before income tax benefit $ 13,144 Statutory taxes $ 2,760 21.0 % State and local income taxes, net of federal income tax effect (a) 339 2.6 % Tax credits: Research and development credit (604) (4.6) % Nondeductible compensation 856 6.5 % Nondeductible meals 137 1.0 % Changes in unrecognized tax benefits (57) (0.4) % Other reconciling items: Percentage depletion (5,398) (41.1) % Deferred tax adjustments (2,429) (18.5) % Other, net (34) (0.3) % Income tax benefit at the effective income tax rate $ (4,430) (33.7) % (a) During the year ended December 31, 2025, state taxes in Louisiana, North Dakota, Mississippi and Pennsylvania made up the majority of the tax effect in this category. The reconciliation from the statutory federal income tax rate to our effective income tax rate, applying ASC 740 prior to the adoption of ASU 2023-09, is as follows: 2024 Income before income tax benefit $ 33,646 Statutory taxes at 21.0% $ 7,066 State and local income taxes 556 Non-deductible expenses 927 Percentage depletion (4,683) R&D and other federal credits (796) Settlements and uncertain tax positions (2,273) Other, net (892) Income tax benefit $ (95) Effective income tax rate (0.3) % We recorded an income tax benefit of $4.4 million for the year ended December 31, 2025 on income before income tax of $13.1 million, or (33.7)%, compared to an income tax benefit of $0.1 million on income before income tax of $33.6 million, or (0.3)%, for the year ended December 31, 2024. The years ended December 31, 2025 and 2024 included $1.9 million and $4.0 million of discrete tax benefits, primarily for deferred tax adjustments and the reversal of uncertain tax provisions, respectively. Excluding the respective $1.9 million and $4.0 million of discrete tax benefits, the effective income tax rate was (19.5)% and 11.5% in 2025 and 2024, respectively. The change in the effective income tax rate for 2025 compared to 2024, excluding the impact of discrete items, is primarily due to an increase in losses at entities that do not benefit from percentage depletion. Losses generated by these entities generate tax deductions at the statutory rate. This shift in the mix of pre-tax income resulted in a benefit tax rate in 2025. In addition, the benefit from percentage depletion is not directly related to the amount of pre-tax income recorded in a period. Accordingly, in periods where income or loss before income tax is relatively small, the proportional effect of the benefit from percentage depletion on the effective tax rate may be significant. When income tax expense is recorded, the benefit from percentage depletion decreases the effective income tax rate, while the effect is to increase the effective income tax rate when a benefit for income taxes is recorded.

Based upon the review of historical earnings and the relevant expiration of carryforwards, including utilization limitations in the various state taxing jurisdictions, we believe the valuation allowances are appropriate and do not expect to release valuation allowances within the next twelve months that would have a significant effect on our financial position or results of operations. Since 2021, we have participated in a voluntary program with the IRS called Compliance Assurance Process (CAP). The objective of CAP is to contemporaneously work with the IRS to achieve federal tax compliance and resolve all or most issues prior to the filing of the tax return. In general, we operate in taxing jurisdictions that provide a statute of limitations period ranging from three to five years for the taxing authorities to review the applicable tax filings. Our tax returns are under routine examination by various taxing authorities. We have not been informed of any material assessment for which an accrual has not been previously provided and would vigorously contest any material assessment. Management believes any potential adjustment would not materially affect our financial condition or results of operations. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC.

The following is a reconciliation of our total gross unrecognized tax benefits, defined as the aggregate tax effect of differences between tax return positions and the benefits recognized in the financial statements for the years ended December 31, 2025 and 2024. Approximately $0.6 million of the gross unrecognized tax benefits as of December 31, 2025 and 2024 relate to permanent items that, if recognized, would impact the effective income tax rate. This amount differs from the gross unrecognized tax benefits presented in the table below due to (1) the deferred tax asset which would be available if the position were not sustained upon audit and (2) the decrease in U.S. federal income taxes which would occur upon the recognition of the state tax benefits included herein. 2025 2024 Balance at January 1 $ 752 $ 6,148 Decreases based on lapse of applicable statute of limitations (61) (5,396) Balance at December 31 $ 691 $ 752 We record interest and penalties on uncertain tax positions as a component of the income tax provision. We recognized a net benefit of less than $0.1 million in interest and penalties related to uncertain tax positions during 2025 and 2024. The total amount of interest and penalties accrued was less than $0.1 million and $0.2 million as of December 31, 2025 and 2024, respectively. We expect the amount of unrecognized tax benefits will change within the next 12 months; however, the change is not expected to have a significant effect on our financial position, results of operations or cash flows. NOTE 14—Retirement Benefit Plans Defined Benefit Plans: During 2025, we terminated the Combined Plan and settled all future obligations by transferring the remaining benefit obligations to a third-party insurance company. The $8.3 million in excess funds from the Combined Plan will be utilized by the NACCO 401(k) plan, which is a qualified replacement plan. These funds will be used for future profit sharing contributions to eligible 401(k) plan participants. The current portion of $5.2 million is recorded on the line Prepaid profit sharing and the long-term portion of $3.1 million is recorded on the line Other non-current assets on the Consolidated Balance Sheets as of December 31, 2025. Although the Combined Plan was over funded, we recognized a non-cash pension settlement charge of $7.8 million on the Pension settlement charge line within the Consolidated Statements of Operations. The $7.8 million settlement charge accelerated the recognition of the net loss recorded in Accumulated other comprehensive loss that would have otherwise been recognized in subsequent periods. As of December 31, 2025, we continue to maintain a Supplemental Retirement Benefit Plan (SERP) that provides benefits based on years of service and average compensation during certain periods. In a previous period, the SERP was amended to freeze all pension benefits. The SERP pays monthly benefits to participants directly out of corporate funds.

Postretirement Health Care: We maintain health care plans which provide benefits to grandfathered eligible retired employees. All of our health care plans have a cap on our share of the costs. The health care plans have network provided benefits which result in cost savings for us. These plans have no assets. Plan benefits are funded at the time they are due to participants.

Defined Contribution Plans: We maintain a defined contribution (401(k)) plan for substantially all employees and provide employer matching contributions based on plan provisions. The plan also provides for a minimum employer contribution. Our matching contributions for these plans were $3.9 million and $3.6 million in 2025 and 2024, respectively. NOTE 15—Business Segments Our operating segments are: (i) Utility Coal Mining, (ii) Contract Mining and (iii) Minerals and Royalties. We determine our reportable segments by first identifying our operating segments, and then by assessing whether any components of these segments constitute a business for which discrete financial information is available and where segment management regularly reviews the operating results of that component. Our President and Chief Executive Officer, who is the Chief Operating Decision Maker (CODM), utilizes Operating profit (loss) to evaluate segment performance and allocate resources. Our CODM considers actual, budgeted and forecasted Operating profit (loss) from operations on a monthly basis for evaluating the performance of each segment and making decisions about allocating capital and other resources to each segment. All financial statement line items below operating profit (other income including interest expense and interest income, the provision (benefit) for income taxes and net income) are presented and discussed within this Form 10-K on a consolidated basis. See Note 1 for additional discussion of our reportable segments. All current operations reside in the U.S. The accounting policies of the reportable segments are described in Note 2. In both 2025 and 2024, three customers accounted for 10% or more of consolidated revenue. The following represents the revenue attributable to each of these entities as a percentage of consolidated revenue for those years: Percentage of Consolidated Revenue Segment 2025 2024 Utility Coal Mining customer 32 % 29 % Contract Mining customer 25 % 24 % Contract Mining customer 10 % 11 % NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC.

NOTE 16—Unconsolidated Subsidiaries Each of our wholly owned Unconsolidated Subsidiaries, within the Utility Coal Mining and Contract Mining segments, meet the definition of a VIE. The Unconsolidated Subsidiaries are capitalized primarily with debt financing provided by or supported by their respective customers, and generally without recourse to us. Although we own 100% of the equity and manage the daily operations of the Unconsolidated Subsidiaries, we have determined that the equity capital provided by us is not sufficient to adequately finance the ongoing activities or absorb any expected losses without additional support from the customers. The customers have a controlling financial interest and have the power to direct the activities that most significantly affect the economic performance of the entities. As a result, we are not the primary beneficiary and therefore do not consolidate these entities' financial positions or results of operations. See Note 1 for a discussion of these entities. The Investment in the unconsolidated subsidiaries and related tax positions totaled $14.8 million and $14.1 million at December 31, 2025 and 2024, respectively. Our risk of loss relating to these entities is limited to our invested capital, which was $6.7 million and $5.5 million at December 31, 2025 and 2024, respectively. NACCO Natural Resources is a party to certain guarantees related to Coyote Creek. Under certain circumstances of default or termination of Coyote Creek’s Lignite Sales Agreement (LSA), NACCO Natural Resources would be obligated to pay a make- NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share, Percentage Data and Oil and Gas Disclosures) F-35
whole amount to Coyote Creek’s third-party lenders. The make-whole amount is based on the excess, if any, of the discounted value of the remaining scheduled debt payments over the principal amount. In addition, in the event Coyote Creek’s LSA is terminated by Coyote Creek’s customers, NACCO Natural Resources is obligated to purchase Coyote Creek’s dragline and rolling stock for the then net book value of those assets. To date, no payments have been required from NACCO Natural Resources since the inception of these guarantees. We believe that the likelihood NACCO Natural Resources would be required to perform under the guarantees is remote, and no amounts related to these guarantees have been recorded. Summarized financial information for the Unconsolidated Subsidiaries is as follows: 2025 2024 Statement of Operations Revenue $ 567,841 $ 542,643 Gross profit $ 71,953 $ 60,256 Income before income taxes $ 59,260 $ 56,831 Net income $ 52,801 $ 49,284 Balance Sheet Current assets $ 121,331 $ 145,655 Non-current assets $ 842,471 $ 816,430 Current liabilities $ 132,158 $ 158,591 Non-current liabilities $ 824,898 $ 798,043 Revenue includes all mine operating costs that are reimbursed by the customers of the Unconsolidated Subsidiaries as well as the compensation per ton of coal, heating unit (MMBtu) or ton of limestone delivered. Reimbursed costs have offsetting expenses and have no impact on income before income taxes. Income before income taxes represents the Earnings of the unconsolidated operations within the Utility Coal Mining and Contract Mining segments. We received dividends of $51.5 million and $48.8 million from the Unconsolidated Subsidiaries in 2025 and 2024, respectively. NOTE 17—Supplemental Oil and Gas Disclosures (Unaudited) The Minerals and Royalties segment derives income primarily by leasing our royalty and mineral interests to third-party exploration and production companies, and, to a lesser extent, other mining companies, granting them the rights to explore, develop, mine, produce, market and sell gas, oil and coal in exchange for royalty payments based on the lessees' sales of those minerals. As an owner of royalty and mineral interests, our access to information concerning activity and operations of our royalty and mineral interests is limited. We do not have information that would be available to a company with working interests in oil and natural gas operations because detailed information is not generally available to owners of royalty and mineral interests. See Note 1, Note 2 and Note 15 for additional discussion of the Minerals and Royalties segment. Capitalized Oil and Natural Gas Costs: Aggregate capitalized costs related to oil and gas royalty and mineral interests with applicable accumulated depreciation, depletion and amortization at December 31 are as follows: 2025 2024 Proved developed $ 17,532 $ 16,720 Proved undeveloped 56,318 52,428 Proved reserves 73,850 69,148 Less: accumulated depreciation, depletion and amortization 9,865 6,061 Net royalty interests in oil and natural gas properties $ 63,985 $ 63,087 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC. AND SUBSIDIARIES (Tabular Amounts in Thousands, Except Per Share, Percentage Data and Oil and Gas Disclosures) F-36
Oil and Natural Gas Reserves: Total net proved reserves are defined as those natural gas and hydrocarbon liquid reserves to Company interests after deducting all royalties, overriding royalties, and reversionary interests owned by outside parties that become effective upon payout of specified monetary balances. Decline curve analysis was used to estimate the remaining reserves of pressure depletion reservoirs with enough historical production data to establish decline trends. Reservoirs under non-pressure depletion drive mechanisms and non-producing reserves were estimated by volumetric analysis, research of analogous reservoirs, or a combination of both. Reserves have been estimated using deterministic and probabilistic methods. All reserves estimates have been prepared using standard engineering practices generally accepted by the petroleum industry and conform to guidelines developed and adopted by the SEC. The following table presents our estimated net proved oil and natural gas reserves as of December 31 based on the reserve report prepared by Haas & Cobb Petroleum Consultants, our independent petroleum engineering firm. All of our reserves are located in the United States.

(1) Bbl. One stock tank barrel, or 42 U.S. gallons liquid volume. (2) Mcf. One thousand cubic feet of natural gas at the contractual pressure and temperature bases. (3) Revisions of previous estimates include technical revisions due to changes in commodity prices, historical and projected performance and other factors. As an owner of mineral and royalty interests, we generally do not have evidence of approval of operators’ development plans. As a result, proved undeveloped reserve estimates are limited to those relatively few locations for which drilling permits have been publicly filed. As of December 31, 2025, PUD reserves consists of 126 wells in various stages of drilling or completions. As of December 31, 2025, approximately 2% of our total proved reserves were classified as PUDs. Standardized Measure of Discounted Future Net Cash Flows: Future cash inflows represent expected revenues from production of period-end quantities of proved reserves based on the 12-month unweighted average of first-day-of-the-month commodity prices for the periods presented. Future cash inflows are computed by applying applicable prices relating to proved reserves to the year-end quantities of those reserves. Future production and costs are derived based on current costs assuming continuation of existing economic conditions. Federal income tax expenses are deducted from future production revenues in the calculation of the standardized measure using the statutory tax rate. We are subject to certain state-based taxes; however, these amounts are not material. The projections should not be viewed as realistic estimates of future cash flows, nor should the standardized measure be interpreted as representing current value to us. Material revisions to estimates of proved reserves may occur in the future; development and production of the reserves may not occur in the periods assumed; actual prices realized are expected to vary significantly from those used; and actual costs may vary. The following table provides the future net cash flows relating to proved oil and gas reserves based on the standardized measure of discounted cash flows as of December 31, 2025: Gross Amounts Statutory tax rate Net Amounts Future cash inflows(3) $ 118,744 Future production costs 5,842 Future net cash flows before income tax expense 112,902 21 % $ 89,193 10% discount to reflect timing of cash flows (43,457) 21 % (34,331) Standardized measure of discounted cash flows $ 69,445 21 % $ 54,862 The following table provides the future net cash flows relating to proved oil and gas reserves based on the standardized measure of discounted cash flows as of December 31, 2024: Gross Amounts Statutory tax rate Net Amounts Future cash inflows(3) $ 119,534 Future production costs 33,308 Future net cash flows before income tax expense 86,226 21 % $ 68,119 10% discount to reflect timing of cash flows (32,580) 21 % (25,739) Standardized measure of discounted cash flows $ 53,646 21 % $ 42,380 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NACCO INDUSTRIES, INC.

The following summarizes the principal sources of change in the standardized measure of discounted future net cash flows during 2025: Gross amounts 2025 2024 January 1 $ 53,646 $ 61,278 Purchases 1,528 522 Extensions and discoveries 13,539 18,426 Revisions of previous estimates (3)(4) 22,696 10,172 Production (30,005) (30,885) Conversions 8,041 (5,867) December 31 $ 69,445 $ 53,646 (3) Requirements for oil and gas reserve estimation and disclosure require that reserve estimates and future cash flows be based on the average market prices for sales of oil and gas on the first calendar day of each month during the year. The benchmark price for WTI crude oil sold at Cushing, OK during 2025 and 2024 was $65.34 and $75.48 per bbl, respectively. The benchmark price for natural gas delivered at Henry Hub during 2025 and 2024 was $3.39 and $2.13 per MMBTU, respectively. Actual future prices and costs are likely to be substantially different from historical prices and costs utilized in the computation of reported amounts. Any analysis or evaluation of the reported amounts should give specific recognition to the computational methods utilized and the limitations inherent therein. (4) Revisions of previous estimates include technical revisions due to changes in commodity prices, historical and projected performance and other factors.

Exhibit 95 MINE SAFETY DISCLOSURES Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, each operator of a coal or other mine is required to include certain mine safety results in its periodic reports filed with the Securities and Exchange Commission. The operation of our mines are subject to regulation by the Federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (the Mine Act). MSHA inspects our mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. The Company has presented information below regarding certain mining safety and health matters for our mining operations for the year ended December 31, 2025. In evaluating this information, consideration should be given to factors such as: (i) the number of citations and orders will vary depending on the size of the mine, (ii) the number of citations issued will vary from inspector to inspector and from mine to mine, and (iii) citations and orders can be contested and appealed, and in that process, are often reduced in severity and amount, and are sometimes vacated. During the year ended December 31, 2025, neither the Company's current mining operations nor our closed mines: (i) were assessed any Mine Act section 104(b) orders for alleged failure to totally abate the subject matter of a Mine Act section 104(a) citation within the period specified in the citation; (ii) were assessed any Mine Act section 110(b)(2) penalties for failure to correct the subject matter of a Mine Act section 104(a) citation within the specified time period, which failure was deemed flagrant (i.e., reckless or repeated failure to make reasonable efforts to eliminate a known violation that substantially and proximately caused, or reasonably could have been expected to cause, death or serious bodily injury); (iii) received any Mine Act section 107(a) imminent danger orders to immediately remove miners; or (iv) received any MSHA written notices under Mine Act section 104(e) of a pattern of violation of mandatory health or safety standards or of the potential to have such a pattern. For the year ended December 31, 2025, we experienced two mining-related fatalities at the Mid Coast Aggregates Quarry. MSHA was properly notified and the event is currently under investigation by MSHA.
The following table sets forth the total number of specific citations and orders, the total dollar value of the proposed civil penalty assessments that were issued by MSHA, the total number of legal actions initiated and resolved before the Federal Mine Safety and Health Review Commission (FMSHRC) during the year ended December 31, 2025, and the total number of legal actions pending before the FMSHRC at December 31, 2025, pursuant to the Mine Act, by individual location: Name of Mine or Quarry (1) Mine Act Section 104 Significant & Substantial Citations (2) Mine Act Section 104(d) Citations Total Dollar Value of Proposed MSHA Assessment Number of Legal Actions Initiated before the FMSHRC for the year ended at December 31, 2025 Number of Legal Actions Resolved before the FMSHRC for the year ended at December 31, 2025 Number of Legal Actions Pending before the FMSHRC at December 31, 2025(3) Coteau (Freedom Mine) — — $ 2,701 — — — Falkirk (Falkirk Mine) — — 2,180 — — — Sabine (South Hallsville No. 1 Mine) — — 726 — — — Demery (Five Forks Mine) — — 912 — — — Caddo Creek (Marshall Mine) — — — — — — Coyote Creek (Coyote Creek Mine) — — 1,762 — — — MLMC (Red Hills Mine) — — — — — — North American Mining Operations: — — — — — — Alico Quarry — — — — — — Center Hill Quarry — — — — — — FEC Quarry — — 765 — — — Inglis Quarry — — — — — — Krome Quarry — — — — — — SCL Quarry — — 642 — — — St. Catherine Quarry — — 549 — — — Seven Diamonds Quarry — — — — — — Central State Aggregates Quarry — — — — — — Little River Quarry — — 245 — — — Mid Coast Aggregates Quarry — — — — — — Newberry Quarry — — 177 — — — Palm Beach Aggregates Quarry — — — — — — Perry Quarry — — — — — — SDI Aggregates Quarry — — — — — — West Florida Aggregates Quarry — — — — — — Titan Corkscrew Quarry — — — — — — White Rock Quarry - North 1 — 4,264 — — — Ash Grove — — 793 — — 1 Fort Myers Quarry — — — — — — Sawtooth — — — — — — Total 1 — $ 15,716 — — 1 (1) Bellaire's and Centennial's closed mines are not included in the table above and did not receive any of the indicated citations.
