Cleveland, Ohio, Wednesday, August 6, 2025 - NACCO Industries® (NYSE: NC) today announced consolidated results for the three and six months ended June 30, 2025.

“NACCO experienced short-term operational challenges this quarter that resulted in a temporary setback to our expectations of delivering increasing operating results," said J.C. Butler, NACCO President and Chief Executive Officer. “These results are also being compared against a particularly strong prior year period. Despite these factors, I continue to have confidence in our businesses, and believe we are well-positioned to achieve meaningful growth moving forward.”

Summary Financial Results:

*Non-GAAP financial measures are defined and reconciled on page 8.

Strong revenue growth was insufficient to overcome short-term operational disruptions and higher unallocated costs, resulting in break-even operating results. Disruptions occurred in both the Utility Coal and Contract Mining segments and included temporarily unfavorable pricing, operational inefficiencies at a customer's power plant with resulting mining inefficiencies, unexpected repairs and maintenance costs and other quarry operational delays.

The prior year quarter included the benefit of a $4.5 million pre-tax gain on sale of land. Increased other income and favorable tax effects in the 2025 second quarter helped minimize the net income decline.

At June 30, 2025, the Company had total debt outstanding of $95.5 million. Total liquidity was $139.9 million, which consisted of $49.4 million of cash and $90.5 million of availability under its revolving credit facility.

In the 2025 second quarter, the Company paid $1.9 million in dividends. As of June 30, 2025, the Company had $7.8 million remaining under its $20 million share repurchase program that expires at the end of 2025.

In the second quarter of 2025, we changed our reportable segment names to help stakeholders more easily associate the business activities with 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. The composition and historical reporting of each segment remained the same.

(1) Operating expenses consist of Selling, general and administrative expenses, Amortization of intangible assets and (Gain) loss on sale of assets.

(2) Segment Adjusted EBITDA is a non-GAAP measure and should not be considered in isolation or as a substitute for GAAP. See non-GAAP explanation and the related reconciliations to GAAP on page 9.

Second-quarter 2025 revenues rose 91% due to an increase in tons delivered at Mississippi Lignite Mining Company. Prior year deliveries were constrained as the power plant served by the mine operated with only one of its two boilers from mid-December 2023 through July 2024.

Utility Coal Mining operating profit and Segment Adjusted EBITDA decreased year-over-year mainly due to lower operating results at Mississippi Lignite Mining Company, a modest decrease in earnings of unconsolidated operations and an increase in operating expenses primarily due to higher employee-related costs.

At Mississippi Lignite Mining Company, continued inefficiencies at the customer's power plant created mining inefficiencies, and thus higher mining costs. In the second quarter of 2024, tons mined exceeded tons sold, allowing these elevated mining costs to be deferred as inventory on the balance sheet. While the cost per ton delivered improved in the second quarter of 2025, the contractual sales price per ton decreased and the volume of tons sold surpassed the volume of tons mined.

This led to the realization of the elevated costs that had been recorded in inventory in prior periods.

Earnings of unconsolidated operations decreased modestly year-over-year due to reduced customer requirements. The decrease in tons delivered was mostly offset by higher pricing, primarily at Falkirk as a result of the expiration of temporary price concessions in June 2024.

(1) Segment Adjusted EBITDA is a non-GAAP measure and should not be considered in isolation or as a substitute for GAAP. See non-GAAP explanation and the related reconciliations to GAAP on page 9.

The Contract Mining segment revenues rose primarily due to an increase in reimbursed costs, which have an offsetting amount in cost of goods sold and therefore no impact on gross profit. Revenues, net of reimbursed costs, grew 3% mainly as a result of an increase in parts sales, largely offset by fewer mined tons delivered due to reduced customer requirements, in part due to certain operational delays.

While the increase in parts sales provides additional support for the growth potential in this business model, the increased parts sales profits were insufficient to offset the effect of lower mined tons delivered, higher operating costs, including unexpected equipment repairs and maintenance costs and increased employee-related costs. This resulted in a decrease in the 2025 second-quarter operating profit and Segment Adjusted EBITDA.

Prior-year 2024 Minerals and Royalties operating profit and Segment Adjusted EBITDA included a $4.5 million gain on sale of land. Excluding this gain, 2025 operating profit and Segment Adjusted EBITDA increased year-over-year primarily due to a 30% increase in revenues principally as a result of higher natural gas prices.

NACCO is a growing diversified natural resource company, strategically positioned to deliver consistent financial returns. 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 disciplined capital allocation, operational expertise and an entrepreneurial yet cautious approach to growth, we have 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.

While the current quarter presented some unexpected operational challenges, our business model is purposely built for durability and resilience. Our foundation rests on a stable base of long-term coal-mining contracts, generating dependable recurring cash flows. As new long-term contracts are added each year in our other businesses, these multi-year agreements create a “layering” effect as their contributions compound. This, combined with income generated by our Mineral and Royalty assets, provide cash flow stability. We remain confident in our ability to deliver improving results during the second half of 2025, with momentum building as we move into 2026.

Over the remainder of the year, we anticipate a substantial increase in consolidated operating profit compared to the first half, although full-year results will be lower than the prior year due in part to $13.6 million of business interruption insurance income recognized in the third quarter of 2024. In addition, we intend to terminate our defined benefit pension plan in the fourth quarter of 2025. Although the plan is currently over funded, a significant non-cash settlement charge is anticipated upon termination. The pension settlement charge and lower operating profit are expected to lead to a substantial year-over-year decrease in net income and EBITDA compared with the 2024 second half and full year.

Our Utility Coal Mining segment, operated by North American Coal®, constitutes the foundation of our business, anchored by a stable portfolio of long-term mining contracts. We anticipate customer demand to remain steady in the second half of 2025 and throughout 2026 at the unconsolidated mining operations. At Mississippi Lignite Mining Company, results for the 2025 second half are expected to improve over the first half of 2025. However, a reduction in the 2025 contractually determined per ton sales price compared with 2024 is anticipated to continue to offset expected improvements in cost efficiencies, causing Mississippi Lignite Mining Company's and the Utility Coal Mining segment's 2025 second half and full year results to decline from the respective prior year levels, which include the business interruption insurance income. Looking ahead, we expect improving profitability for this segment in 2026, driven by continued stable earnings at our unconsolidated operations and anticipated improvements at Mississippi Lignite Mining Company in both sales price and cost per ton delivered, particularly if the customer's power plant is able to operate more consistently.

The Contract Mining segment, operated by North American Mining®, represents our mining growth platform, benefiting from ongoing geographic and mineral expansion and the signing of new, more favorable long-term contracts. Each new contract perpetuates the compounding effect that underpins our growth strategy—much like building an annuity portfolio over time. For example, in 2024, the Contract Mining segment executed three new or amended contracts, which are projected to generate approximately $20 million in after-tax net present value cash flows over contract terms ranging from 6 to 20 years. Our expanding pipeline of potential deals and continued engagement with customers position this segment as a key pillar for future growth.

Sawtooth Mining, a North American Mining subsidiary, is the exclusive provider of comprehensive mining services at Thacker Pass, which is owned through a joint venture between Lithium Americas Corp. (TSX: LAC) (NYSE: LAC) and General Motors Holdings LLC. Sawtooth will supply all of the lithium-bearing ore requirements for Thacker Pass, which is currently under construction. This project is currently providing stable income during the construction phase and will contribute enhanced income and long-term cash flows once lithium production commences.

Phase 1 lithium production is estimated to begin in late 2027.

Near term, while overall customer demand within the Contract Mining segment is expected to remain stable year-over-year, profitability improvements in the 2025 second half and full year are expected to be driven by operational efficiencies and an increased focus on parts sales. This momentum is expected to continue into 2026.

The Minerals and Royalties segment, led by Catapult Minerals Partners, has constructed a high-quality, diversified portfolio of oil and gas mineral and royalty interests in the United States. The business is a scalable platform for growth, with its data-driven approach to portfolio expansion and disciplined capital deployment providing a distinct competitive advantage in the U.S. market.

In July 2025, Catapult completed a $4.2 million acquisition of mineral interests within the Midland Basin which included 10,500 gross acres and approximately 400 net royalty acres. The acquisition includes a mix of producing wells, as well as additional upside opportunities through future development with existing operators in the area. This business also has an investment in a company that holds non-operated working interests in oil and natural gas assets. These investments are expected to contribute to the anticipated improvement in second-half operating profit compared with both the first half of 2025 and second half of 2024. Improvements in operating profit are expected to continue into 2026.

Mitigation Resources of North America® provides stream and wetland mitigation solutions, as well as comprehensive reclamation and restoration construction services. Mitigation Resources, underpinned by a strong reputation and clear competitive strengths, is an avenue for continued expansion into new markets. This business, while currently variable in performance due to permit and project timing, is expected to achieve key milestones in profitability in 2026 and move toward more consistent results over time as new projects are layered on top of existing projects.

We continue to invest in our businesses to drive future growth. Based on the current project pipeline, we anticipate capital expenditures of up to a total of $86 million in 2025, with the majority earmarked for future business development— the kind of prudent reinvestment that generates exponential, long-term value creation. We project a substantially lower use of cash for the 2025 full year compared with 2024 as we begin to harvest returns from prior investments and expect a steady increase in annual cash flow generation beginning in 2026.

Our conservative approach to maintaining a strong capital structure and operating discipline minimizes risk, while the compounding effect of layered 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, that others 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.
