18Investor Presentation August 2026 Utility Coal – Mississippi Lignite Mining Company (MLMC) Performance influenced by customer conditions Smaller Share of NACCO Each Year Takeaways: • Results can be uneven quarter to quarter as they are linked to customer's power plant performance • Current mine area reserves sufficient to meet contractual requirements • MLMC is one part of a larger portfolio; not the NACCO thesis MLMC and the Red Hills Power Plant are each committed through April 2032, with the Red Hills Power Plant supplying the Tennessee Valley Authority (TVA). MLMC bears the mine’s operating costs, capital needs and final reclamation. Current Focus Areas: • Red Hills Plant performance • TVA Dispatch and coal demand • Pricing formula and effect on inventory costing • Customer collectibility issues Key Facts: • Exclusive lignite supplier to Red Hills Power Plant through April 2032 • TVA Dispatch: Drives plant demand • Different Business Model: MLMC responsible for all costs and final reclamation

24Investor Presentation August 2026 Non-GAAP Disclosure This presentation contains non-GAAP financial measures. Included in this presentation are reconciliations of these non-GAAP financial measures to the most directly comparable financial measures calculated in accordance with U.S. generally accepted accounting principles ("GAAP"). Consolidated EBITDA, Consolidated Adjusted EBITDA and Segment Adjusted EBITDA are measures of income (loss) that differ from financial results measured in accordance with GAAP. Consolidated EBITDA, Consolidated Adjusted EBITDA and Segment Adjusted EBITDA in this presentation are provided solely as supplemental non-GAAP disclosures of operating results. Management believes these non-GAAP financial measures assist investors in understanding the results of operations of NACCO Industries, Inc. and its subsidiaries and aid in understanding comparability of results. In addition, management evaluates results using these non-GAAP financial measures. We have also provided certain forward-looking statements regarding Consolidated EBITDA. We have not reconciled this forward- looking non-GAAP financial measure to the corresponding GAAP financial measure because outlook for the various reconciling items is not provided. We are unable to provide outlook for these reconciling items because we cannot determine their probable significance, as certain items are outside of our control and cannot be reasonably predicted since these items could vary significantly from period to period. Accordingly, a reconciliation to the corresponding GAAP financial measure is not available without unreasonable effort. NACCO defines non-GAAP measures as follows: ▪ Consolidated EBITDA is net income before income taxes, plus net interest expense and depreciation, depletion and amortization expense; ▪ Consolidated Adjusted EBITDA is net income before asset impairment charges, pension settlement charge and income taxes, plus net interest expense and depreciation, depletion and amortization expense; and ▪ Segment Adjusted EBITDA is segment operating profit before asset impairment charges and depreciation, depletion and amortization expense.
